                                    PART I

ITEM 1.     BUSINESS

General

      NL  Industries,  Inc.,  organized  as a New  Jersey  corporation  in 1891,
conducts its operations through its principal wholly-owned subsidiaries, Kronos,
Inc. and Rheox,  Inc. Valhi,  Inc. and Tremont  Corporation,  each affiliates of
Contran Corporation,  hold 56% and 18%, respectively, of NL's outstanding common
stock.  Contran holds,  directly or through  subsidiaries,  approximately 91% of
Valhi's and 44% of Tremont's  outstanding  common  stock.  Substantially  all of
Contran's outstanding voting stock is held by trusts established for the benefit
of the children and  grandchildren  of Harold C. Simmons of which Mr. Simmons is
the sole trustee.  Mr. Simmons, the Chairman of the Board of NL and the Chairman
of the Board, President and Chief Executive Officer of each of Contran and Valhi
and a director of Tremont,  may be deemed to control each of such companies.  NL
and its consolidated  subsidiaries are sometimes referred to herein collectively
as the "Company."

      Kronos is the world's fourth largest producer of titanium dioxide pigments
("TiO2")  with an estimated  11% share of  worldwide  TiO2 sales volume in 1996.
Approximately  one-half of Kronos' 1996 sales volume was in Europe, where Kronos
is the second largest producer of TiO2. In 1996, Kronos accounted for 86% of the
Company's  sales and 63% of its operating  income.  Rheox is the world's largest
producer of rheological additives for solvent-based systems.

      The Company's  objective is to maximize total  shareholder  returns by (i)
focusing on continued  cost control,  (ii)  investing in certain cost  effective
debottlenecking  projects to increase TiO2 production capacity and productivity,
and (iii) deleveraging as excess liquidity becomes available.

Kronos

  Industry

      Titanium  dioxide  pigments  are  chemical  products  used  for  imparting
whiteness, brightness and opacity to a wide range of products, including paints,
plastics,   paper,   fibers  and   ceramics.   TiO2  is   considered   to  be  a
"quality-of-life"  product with demand affected by the gross domestic product in
various regions of the world.

      Demand,  supply and  pricing  within the TiO2  industry is  cyclical,  and
changes in industry economic  conditions can significantly  impact the Company's
earnings and operating cash flow. The Company's average TiO2 selling prices have
been  declining  since the last half of 1995,  which  followed an upturn in TiO2
prices that began in the third quarter of 1993. The Company  expects TiO2 prices
will  begin to  increase  during  the  second  quarter  of 1997 as the impact of
recently-announced  price  increases  begin to take  effect.  Despite the recent
decline in TiO2 average  selling prices,  industry-wide  demand for TiO2 grew in
1996, and Kronos' record 1996 sales volume was about 6% higher than 1995. The

                                    -1-





Company's expectations as to the future prospects of the TiO2 industry are based
upon  several  factors  beyond  the  Company's  control,  principally  continued
worldwide  growth of gross  domestic  product and the  absence of  technological
advancements in or modifications to TiO2 processes that would result in material
and  unanticipated  increases  in  production  efficiencies.  To the extent that
actual  developments differ from the Company's  expectations,  the Company's and
the TiO2 industry's future performance could be unfavorably affected.

      Kronos has an  estimated  18% share of European  TiO2 sales  volume and an
estimated 12% share of North American TiO2 sales volume.  Consumption per capita
in the United  States and Western  Europe far exceeds that in other areas of the
world and these regions are expected to continue to be the largest  consumers of
TiO2. A significant market for TiO2 could emerge in Eastern Europe, the Far East
and  China if the  economies  in these  countries  develop  to the  point  where
quality-of-life products, including TiO2, are in greater demand. Kronos believes
that, due to its strong  presence in Western  Europe,  it is well  positioned to
participate  in  growth  in the  Eastern  European  market.  Geographic  segment
information is contained in Note 3 to the Consolidated Financial Statements.

  Products and operations

      The Company  believes  that there are no effective  substitutes  for TiO2.
However,  extenders  such as  kaolin  clays,  calcium  carbonate  and  polymeric
opacifiers  are used in a number of Kronos'  markets.  Generally,  extenders are
used to reduce to some extent the  utilization  of higher cost TiO2.  The use of
extenders has not  significantly  affected TiO2 consumption over the past decade
because  extenders  generally  have,  to date,  failed to match the  performance
characteristics of TiO2. The Company believes that the use of extenders will not
materially alter the growth of the TiO2 business in the foreseeable future.

      Kronos  currently  produces over 40 different TiO2 grades,  sold under the
Kronos and Titanox trademarks, which provide a variety of performance properties
to meet  customers'  specific  requirements.  Kronos'  major  customers  include
domestic and international paint, plastics and paper manufacturers.

      Kronos is one of the world's  leading  producers  and  marketers  of TiO2.
Kronos and its distributors and agents sell and provide  technical  services for
its  products to over 4,000  customers  with the majority of sales in Europe and
North America.  Kronos'  international  operations are conducted  through Kronos
International,  Inc., a  Germany-based  holding company formed in 1989 to manage
and  coordinate  the  Company's  manufacturing  operations  in Germany,  Canada,
Belgium and Norway, and its sales and marketing activities in over 100 countries
worldwide.  Kronos and its predecessors have produced and marketed TiO2 in North
America and Europe for over 70 years.  As a result,  Kronos believes that it has
developed  considerable  expertise  and  efficiency  in the  manufacture,  sale,
shipment and service of its products in domestic and international  markets.  By
volume,  approximately  one-half of Kronos' 1996 TiO2 sales were to Europe, with
37% to North America and the balance to export markets.

      Kronos is also  engaged  in the  mining  and sale of  ilmenite  ore (a raw
material used in the sulfate pigment  production  process),  and the manufacture
and sale of iron-based  water treatment  chemicals  (derived from co-products of
the

                                    -2-





pigment production  processes).  Water treatment chemicals are used as treatment
and conditioning agents for industrial effluents and municipal wastewater and in
the manufacture of iron pigments.

  Manufacturing process and raw materials

      TiO2 is  manufactured  by Kronos using both the  chloride  process and the
sulfate process. Approximately two-thirds of Kronos' current production capacity
is based on its chloride  process  which  generates  less waste than the sulfate
process.  Although most end-use applications can use pigments produced by either
process,  chloride-process  pigments are generally preferred in certain coatings
and plastics applications,  and sulfate-process pigments are generally preferred
for  certain  paper,  fibers and  ceramics  applications.  Due to  environmental
factors and customer  considerations,  the  proportion  of TiO2  industry  sales
represented   by   chloride-process   pigments   has   increased   relative   to
sulfate-process pigments in the past few years, and chloride-process  production
facilities in 1996 represented approximately 56% of industry capacity.

      Kronos  produced  373,000  metric  tons of TiO2 in 1996,  compared  to the
record  393,000  metric tons  produced in 1995 and 357,000  metric tons in 1994.
Kronos  reduced its  production  rates in early 1996 in  response  to  softening
demand and its high  inventory  levels at the end of 1995.  As demand  increased
during 1996 and inventories declined, Kronos' production rates were increased to
near  full  capacity  in  late  1996.  Kronos  believes  its  annual  attainable
production capacity is approximately 400,000 metric tons, including its one-half
interest in the joint  venture-owned  Louisiana  plant (see "TiO2  manufacturing
joint  venture").  Following the  completion of the $35 million  debottlenecking
expansion of its Leverkusen,  Germany  chloride-process  plant in late 1997, the
Company expects its worldwide annual attainable  production capacity to increase
to approximately 410,000 metric tons.

      The primary raw materials used in the TiO2 chloride production process are
chlorine,  coke  and  titanium-containing  feedstock  derived  from  beach  sand
ilmenite and natural  rutile ore.  Chlorine and coke are available from a number
of  suppliers.  Titanium-containing  feedstock  suitable for use in the chloride
process  is  available  from a limited  number of  suppliers  around  the world,
principally in Australia,  Africa,  Canada, India and the United States.  Kronos
purchases  slag  refined  from beach sand  ilmenite  from  Richards Bay Iron and
Titanium  (Proprietary)  Limited (South Africa),  approximately  50% of which is
owned by RTZ Iron and  Titanium  Inc.  ("RTZ"),  an indirect  subsidiary  of RTZ
Corp.,  under a long-term  supply contract that expires in 2000.  Natural rutile
ore, another chloride  feedstock,  is purchased primarily from RGC Mineral Sands
Limited (Australia), under a long-term supply contract that expires in 2000. Raw
materials under these contracts are expected to meet Kronos' chloride  feedstock
requirements  over the next  several  years.  The  Company  does not  expect  to
encounter  difficulties  obtaining new long-term  supply  contracts prior to the
expiration of its existing contracts.

      The primary raw materials used in the TiO2 sulfate  production process are
sulfuric acid and titanium-containing  feedstock derived primarily from rock and
beach sand  ilmenite.  Sulfuric  acid is available  from a number of  suppliers.
Titanium-containing feedstock suitable for use in the sulfate process is

                                    -3-





available from a limited number of suppliers  around the world.  Currently,  the
principal  active sources are located in Norway,  Canada,  Australia,  India and
South   Africa.   As  one  of  the  few   vertically-integrated   producers   of
sulfate-process  pigments,  Kronos operates a Norwegian rock ilmenite mine which
provided  all of Kronos'  feedstock  for its  European  sulfate-process  pigment
plants in 1996.  Kronos  also  purchases  sulfate  grade  slag  under  contracts
negotiated  annually with RTZ and,  through 1997,  with Tinfos Titanium and Iron
K/S.

      Kronos believes the availability of titanium-containing feedstock for both
the chloride  and sulfate  processes  is adequate  through the  remainder of the
decade.  Kronos does not anticipate  experiencing  any  interruptions of its raw
material supplies because of its long-term supply contracts.  However, political
and economic  instability in the countries from which the Company  purchases its
raw material supplies could adversely affect the availability of such feedstock.

  TiO2 manufacturing joint venture

      Subsidiaries of Kronos and Tioxide Group, Ltd., a wholly-owned  subsidiary
of Imperial Chemicals  Industries PLC ("Tioxide"),  each own a 50%-interest in a
manufacturing   joint   venture.   The  joint   venture   owns  and  operates  a
chloride-process TiO2 plant located in Lake Charles, Louisiana.  Production from
the plant is shared equally by Kronos and Tioxide (the  "Partners")  pursuant to
separate offtake agreements.

      A  supervisory  committee,  composed  of four  members,  two of  whom  are
appointed  by each  Partner,  directs  the  business  and  affairs  of the joint
venture,  including production and output decisions.  Two general managers,  one
appointed and  compensated by each Partner,  manage the daily  operations of the
joint venture acting under the direction of the supervisory committee.

      The manufacturing joint venture is intended to be operated on a break-even
basis and, accordingly, Kronos' transfer price for its share of TiO2 produced is
equal to its share of the joint venture's production costs and interest expense.
Kronos'  share of the  production  costs  are  reported  as cost of sales as the
related TiO2 acquired from the joint venture is sold, and its share of the joint
venture's interest expense is reported as a component of interest expense.

  Competition

      The TiO2 industry is highly  competitive.  During the early 1990s,  supply
exceeded  demand,   primarily  due  to  new  chloride-process   capacity  coming
on-stream. Relative supply/demand relationships, which had a favorable impact on
industry-wide  prices  during the late 1980s,  had a negative  impact during the
subsequent  downturn.  During  1994 and the first  half of 1995,  strong  demand
growth  improved  industry  capacity  utilization  and  resulted in increases in
worldwide TiO2 prices.  Kronos believes that the increased  demand was partially
due to customers stocking inventories. In the second half of 1995 and first half
of 1996, customers reduced inventory levels, which reduced industry-wide demand.
Demand improved in the second half of 1996,  indicating,  Kronos believes,  that
customer  inventories had returned to more-normal  levels.  Price increases were
announced in late 1996 by most major TiO2 producers,  including Kronos,  and the
results  of such  announcements  are  expected  to  impact  second-quarter  1997
operating results.

                                    -4-





No  assurance  can be given  that price  trends  will  conform to the  Company's
expectations.

      Capacity additions that are the result of construction of grassroot plants
in the  worldwide  TiO2 market  require  significant  capital  expenditures  and
substantial   lead  time  (typically  three  to  five  years  in  the  Company's
experience) for, among other things, planning, obtaining environmental approvals
and construction. No grassroot plants have been announced, but industry capacity
can  be  expected  to   increase   as  Kronos  and  its   competitors   complete
debottlenecking  projects at  existing  plants.  Based on the factors  described
under the caption  "Kronos-Industry" above, the Company expects that the average
annual  increase in industry  capacity from announced  debottlenecking  projects
will be less than the average  annual demand growth for TiO2 during the next few
years.

      Kronos  competes  primarily  on the basis of price,  product  quality  and
technical  service,  and the  availability of high  performance  pigment grades.
Although certain TiO2 grades are considered specialty pigments,  the majority of
grades and  substantially  all of Kronos'  production are  considered  commodity
pigments with price generally  being the most  significant  competitive  factor.
Kronos has an estimated 11% share of worldwide  TiO2 sales volume,  and believes
that it is the  leading  marketer  of TiO2 in a number of  countries,  including
Germany and Canada.

      Kronos'  principal  competitors  are E.I.  du Pont de  Nemours & Co.  ("Du
Pont");   Imperial  Chemical   Industries  PLC  (Tioxide)  ("ICI");   Millennium
Chemicals,  Inc.  (Millennium  Inorganic  Chemicals,  Inc.),  formerly a unit of
Hanson PLC; Kemira Oy;  Kerr-McGee  Corporation;  Ishihara Sangyo Kaisha,  Ltd.;
Bayer AG; and Thann et Mulhouse. In January 1997, ICI announced its intention to
spin off to its  shareholders  its  Tioxide  unit in the  next  six to  eighteen
months.  These eight competitors have estimated  individual  worldwide shares of
TiO2 sales volume  ranging from 3% to 21%, and an estimated  aggregate 75% share
of TiO2 sales volume.  Du Pont has about one-half of total U.S. TiO2  production
capacity and is Kronos' principal North American competitor.

Rheox

  Products and operations

      Rheological additives control the flow and leveling  characteristics for a
variety of products, including paints, inks, lubricants, sealants, adhesives and
cosmetics. Organoclay rheological additives are clays which have been chemically
reacted  with  organic  chemicals  and  compounds.  Rheox  produces  rheological
additives for both solvent-based and water-based  systems.  Rheox is the world's
largest producer of rheological  additives for solvent-based systems and is also
a supplier of rheological  additives used in  water-based  systems.  Rheological
additives for solvent-based  systems accounted for about 80% of Rheox's sales in
1996, with the remainder being principally rheological additives for water-based
systems.  Rheox  introduced a number of new products  during the past few years,
the majority of which are for water-based systems,  which are sold into a larger
market than solvent-based  systems. The Company believes  water-based  additives
will account for an increasing portion of its sales in the long term.


                                    -5-





      Sales of rheological  additives  generally  follow gross domestic  product
growth  in  Rheox's  principal  markets  and are  influenced  by the  volume  of
shipments  of the  worldwide  coatings  industry.  Since a  portion  of  Rheox's
rheological  additives  are used in  industrial  coatings,  plant and  equipment
spending has an influence on demand for this product line.

  Manufacturing process and raw materials

      The  primary  raw  materials  utilized in the  production  of  rheological
additives are bentonite clays, hectorite clays, quaternary amines,  polyethylene
waxes and castor oil derivatives.  Bentonite clays are currently purchased under
a three-year  contract,  renewable  through  2004,  with a subsidiary of Dresser
Industries,  Inc.  ("Dresser"),  which has  significant  bentonite  reserves  in
Wyoming.  This  contract  assures  Rheox the right to purchase  its  anticipated
requirements  of  bentonite  clays for the  foreseeable  future,  and  Dresser's
reserves are believed to be  sufficient  for such purpose.  Hectorite  clays are
mined from  Company-owned  reserves in Newberry Springs,  California,  which the
Company  believes are adequate to supply its needs for the  foreseeable  future.
The Newberry Springs ore body contains the largest known  commercial  deposit of
hectorite clays in the world.  Quaternary amines are purchased  primarily from a
joint venture that is 50%-owned by Rheox and are also generally available on the
open market from a number of suppliers.  Castor oil-based  rheological additives
are  purchased  from  sources  outside  the  United  States.  Rheox has a supply
contract  with a  manufacturer  of these  products  which may not be  terminated
without 180 days notice by either party.

  Competition

      Competition  in the  specialty  chemicals  industry  generally  focuses on
product uniqueness,  quality and availability,  technical service,  knowledge of
end-use  applications and price.  Rheox's principal  competitors for rheological
additives for  solvent-based  systems are Laporte PLC and Sud-Chemie AG. Rheox's
principal  competitors  for  water-based  systems  are Rohm  and  Haas  Company,
Hercules Incorporated, and Union Carbide Corporation.

Research and Development

      The  Company's  expenditures  for  research  and  development  and certain
technical  support  programs have averaged  approximately  $11 million  annually
during  the  past  three  years  with  Kronos   accounting   for   approximately
three-quarters  of the annual  spending.  Research  and  development  activities
related to TiO2 are conducted  principally at the Leverkusen,  Germany facility.
Such activities are directed  primarily  toward  improving both the chloride and
sulfate  production  processes,  improving  product  quality  and  strengthening
Kronos' competitive position by developing new pigment applications.  Activities
relating to rheological  additives are conducted  primarily in the United States
and are  directed  towards  the  development  of new  products  for  water-based
systems,  environmental  applications and new end-use  applications for existing
product lines.


                                    -6-





Patents and Trademarks

      Patents  held for  products and  production  processes  are believed to be
important to the Company and contribute to the continuing business activities of
Kronos and Rheox.  The  Company  continually  seeks  patent  protection  for its
technical developments, principally in the United States, Canada and Europe, and
from time to time enters into  licensing  arrangements  with third  parties.  In
connection with the formation of the  manufacturing  joint venture with Tioxide,
Kronos and certain of its subsidiaries  exchanged  proprietary  chloride process
and product technologies with Tioxide and certain of its affiliates. Use by each
recipient of the other's  technology in Europe was  restricted  through  October
1996. The Company does not expect that the technology  sharing  arrangement with
Tioxide will  materially  impact the Company's  competitive  position within the
TiO2 industry. See "Kronos - TiO2 manufacturing joint venture."

      The Company's major trademarks,  including Kronos,  Titanox and Rheox, are
protected by  registration  in the United States and  elsewhere  with respect to
those products it manufactures and sells.

Foreign Operations

      The Company's chemical  businesses have operated in international  markets
since the  1920s.  Most of Kronos'  current  production  capacity  is located in
Europe and Canada,  and approximately  one-third of Rheox's sales in each of the
past   three   years   have  been  from   European   production.   Approximately
three-quarters  of the  Company's  1996  consolidated  sales  were  to  non-U.S.
customers,  including  13% to  customers  in areas other than Europe and Canada.
Foreign  operations are subject to, among other things,  currency  exchange rate
fluctuations and the Company's  results of operations have in the past been both
favorably and unfavorably  affected by fluctuations in currency  exchange rates.
Effects of fluctuations in currency  exchange rates on the Company's  results of
operations  are discussed in Item 7.  "Management's  Discussion  and Analysis of
Financial Condition and Results of Operations."

      Political and economic  uncertainties in certain of the countries in which
the Company operates may expose it to risk of loss. The Company does not believe
that there is currently any  likelihood  of material  loss through  political or
economic  instability,  seizure,  nationalization  or similar event. The Company
cannot predict,  however, whether events of this type in the future could have a
material  effect on its  operations.  The  Company's  manufacturing  and  mining
operations are also subject to extensive and diverse environmental regulation in
each of the  foreign  countries  in which  they  operate.  See  "Regulatory  and
Environmental Matters."

Customer Base and Seasonality

      The Company  believes that neither its aggregate sales nor those of any of
its principal  product groups are  concentrated in or materially  dependent upon
any single customer or small group of customers.  Neither the Company's business
as a whole nor that of any of its  principal  product  groups is seasonal to any
significant  extent.  Due in part to the  increase  in paint  production  in the
spring to meet the spring and summer painting season demand, TiO2 sales are

                                    -7-





generally higher in the second and third calendar quarters than in the first and
fourth calendar quarters.  Sales of rheological  additives are influenced by the
worldwide industrial protective coatings industry, where second calendar quarter
sales are generally the strongest.

Employees

      As of December 31, 1996, the Company employed approximately 3,100 persons,
excluding the joint venture  employees,  with approximately 400 employees in the
United States and approximately 2,700 at sites outside the United States. Hourly
employees in production facilities worldwide,  including the TiO2 joint venture,
are  represented  by a variety of labor  unions,  with labor  agreements  having
various expiration dates. The Company believes its labor relations are good.

Regulatory and Environmental Matters

      Certain  of the  Company's  businesses  are and have been  engaged  in the
handling,  manufacture  or use of substances or compounds that may be considered
toxic or hazardous within the meaning of applicable  environmental laws. As with
other  companies  engaged  in  similar  businesses,  certain  past  and  current
operations and products of the Company have the potential to cause environmental
or other damage.  The Company has implemented and continues to implement various
policies  and programs in an effort to minimize  these risks.  The policy of the
Company  is  to  achieve  compliance  with  applicable  environmental  laws  and
regulations  at all its  facilities  and to strive to improve its  environmental
performance.  It  is  possible  that  future  developments,   such  as  stricter
requirements of environmental laws and enforcement  policies  thereunder,  could
adversely   affect   the   Company's   production,   handling,   use,   storage,
transportation,  sale or disposal of such  substances  as well as the  Company's
consolidated financial position, results of operations or liquidity.

      The  Company's  U.S.  manufacturing  operations  are  governed  by federal
environmental and worker health and safety laws and regulations, principally the
Resource  Conservation and Recovery Act, the Occupational Safety and Health Act,
the Clean Air Act, the Clean Water Act, the Safe  Drinking  Water Act, the Toxic
Substances   Control   Act  and  the   Comprehensive   Environmental   Response,
Compensation  and  Liability  Act, as amended by the  Superfund  Amendments  and
Reauthorization  Act  ("CERCLA"),  as well as the  state  counterparts  of these
statutes.  The Company  believes  that all of its U.S.  plants and the Louisiana
plant owned and operated by the joint venture are in substantial compliance with
applicable  requirements of these laws or compliance  orders issued  thereunder.
From time to time,  the  Company's  facilities  may be subject to  environmental
regulatory enforcement under such statutes. Resolution of such matters typically
involves the establishment of compliance programs. Occasionally,  resolution may
result in the payment of penalties, but to date such penalties have not involved
amounts having a material adverse effect on the Company's consolidated financial
position, results of operations or liquidity.

      The Company's  European and Canadian  production  facilities operate in an
environmental  regulatory framework in which governmental  authorities typically
are granted broad discretionary powers which allow them to issue operating

                                    -8-





permits  required for the plants to operate.  The Company  believes that all its
plants are in substantial compliance with applicable environmental laws.

      While the laws  regulating  operations of industrial  facilities in Europe
vary from country to country, a common regulatory denominator is provided by the
European  Union (the  "EU").  Germany,  Belgium and the United  Kingdom,  each a
member of the EU,  follow the  initiatives  of the EU.  Norway,  although  not a
member,  generally  patterns its environmental  regulatory actions after the EU.
The Company  believes that Kronos is in substantial  compliance  with agreements
reached  with  European  environmental  authorities  and with an EU directive to
control the effluents produced by TiO2 production  facilities.  The Company also
believes  that  Rheox  is  in  substantial  compliance  with  the  environmental
regulations in Germany and the United Kingdom.

      The  Company  has a contract  with a third  party to treat  certain of its
Leverkusen and Nordenham,  Germany sulfate-process  effluents.  Either party may
terminate  the  contract  after  giving  four years  notice  with  regard to the
Nordenham plant. After December 1998 and under certain circumstances, Kronos may
terminate  the  contract  after  giving six  months  notice  with  regard to the
Leverkusen plant.

      In order to reduce sulfur dioxide emissions into the atmosphere consistent
with applicable environmental regulations, Kronos is completing the installation
of off-gas  desulfurization  systems at its  Norwegian  and German  plants at an
estimated cost of $30 million.  The manufacturing  joint venture installed a $16
million  off-gas  desulfurization  system  at the  Louisiana  plant  and  Kronos
completed an $11 million water treatment  chemical  purification  project at its
Leverkusen, Germany facility in 1996.

      The Quebec provincial  government has environmental  regulatory  authority
over Kronos' Canadian chloride and  sulfate-process  TiO2 production facility in
Varennes,  Quebec. The provincial  government  regulates discharges into the St.
Lawrence River. In May 1992, the Quebec provincial  government  extended Kronos'
right to discharge effluents from its Canadian  sulfate-process  TiO2 plant into
the  St.  Lawrence  River  until  June  1994.  Kronos  completed  a  waste  acid
neutralization  facility  and  discontinued  discharging  untreated  waste  acid
effluents  into  the St.  Lawrence  River  in  June  1994.  Notwithstanding  the
foregoing,  in March 1993, Kronos' Canadian  subsidiary and two of its directors
were charged by the Canadian  federal  government  with five  violations  of the
Canadian  Fisheries Act relating to discharges  into the St. Lawrence River from
the  Varennes  sulfate-process  TiO2  plant.  The  monetary  penalty  for  these
violations, if proven, could be up to Canadian $15 million.  Additional charges,
if brought,  could involve additional penalties.  The Company believes that this
charge is  inconsistent  with the extension  granted by provincial  authorities,
referred to above,  and is vigorously  contesting  the charge.  A trial date has
been set for May 1997.

      The Company's capital  expenditures  related to its ongoing  environmental
protection and improvement  programs are currently  expected to be approximately
$3 million in 1997 and $5 million in 1998.


                                    -9-





      The Company has been named as a defendant,  potentially  responsible party
("PRP"),  or both, pursuant to CERCLA and similar state laws in approximately 75
governmental  and private actions  associated with waste disposal sites,  mining
locations and facilities currently or previously owned,  operated or used by the
Company, or its subsidiaries, or their predecessors, certain of which are on the
U.S.   Environmental   Protection   Agency's  ("U.S.  EPA")  Superfund  National
Priorities List or similar state lists. See Item 3. "Legal Proceedings."

ITEM 2.     PROPERTIES

      Kronos currently  operates four TiO2 facilities in Europe  (Leverkusen and
Nordenham, Germany;  Langerbrugge,  Belgium; and Fredrikstad,  Norway). In North
America,  Kronos has a facility in  Varennes,  Quebec,  Canada and,  through the
manufacturing  joint venture  described above, a one-half interest in a plant in
Lake  Charles,  Louisiana.  Certain of the  Company's  properties  collateralize
long-term debt agreements and the Company's Nordenham TiO2 plant has a lien that
secures  the  German  tax  authorities,   pending   resolution  of  certain  tax
litigation. See Notes 10 and 13 to the Consolidated Financial Statements.

      Kronos'  principal German operating  subsidiary  leases the land under its
Leverkusen  TiO2 production  facility  pursuant to a lease expiring in 2050. The
Leverkusen  facility,  with about  one-third of Kronos'  current TiO2 production
capacity,  is located within an extensive  manufacturing  complex owned by Bayer
AG,  and  Kronos  is the only  unrelated  party so  situated.  Under a  separate
supplies  and  services  agreement  expiring in 2011,  Bayer  provides  some raw
materials, auxiliary and operating materials and utilities services necessary to
operate the  Leverkusen  facility.  Both the lease and the supplies and services
agreement  restrict  Kronos'  ability  to  transfer  ownership  or  use  of  the
Leverkusen facility.

      All of Kronos' principal production  facilities described above are owned,
except for the land under the  Leverkusen  facility.  Kronos has a  governmental
concession with an unlimited term to operate its ilmenite mine in Norway.

      Specialty  chemicals are produced by Rheox at  facilities  in  Charleston,
West Virginia;  Newberry Springs,  California; St. Louis, Missouri;  Livingston,
Scotland and  Nordenham,  Germany.  A portion of the land under the  Livingston,
Scotland  facility  is leased  from an  unrelated  party;  all of the  remaining
production facilities are owned.

ITEM 3.     LEGAL PROCEEDINGS

  Lead pigment litigation

      The Company was formerly  involved in the manufacture of lead pigments for
use in paint and lead-based  paint. The Company has been named as a defendant or
third party defendant in various legal proceedings alleging that the Company and
other  manufacturers  are  responsible  for personal  injury and property damage
allegedly  associated  with the use of lead pigments.  The Company is vigorously
defending such litigation. Considering the Company's previous involvement in the
lead pigment and  lead-based  paint  businesses,  there can be no assurance that
additional  litigation,  similar to that described below,  will not be filed. In
addition, various legislation and administrative regulations  have, from time to

                                    -10-





time,  been enacted or proposed that seek to (a) impose  various  obligations on
present  and former  manufacturers  of lead  pigment and  lead-based  paint with
respect to asserted health concerns associated with the use of such products and
(b) effectively  overturn court decisions in which the Company and other pigment
manufacturers  have  been  successful.  Examples  of such  proposed  legislation
include  bills which would  permit civil  liability  for damages on the basis of
market share. No legislation or regulations  have been enacted to date which are
expected  to  have a  material  adverse  effect  on the  Company's  consolidated
financial  position,  results of operations  or  liquidity.  The Company has not
accrued  any  amounts  for  the  pending  lead  pigment  and  lead-based   paint
litigation.  There is no  assurance  that the  Company  will  not  incur  future
liability  in  respect  of this  pending  litigation  in  view  of the  inherent
uncertainties  involved in court and jury rulings in pending and possible future
cases. However,  based on, among other things, the results of such litigation to
date, the Company  believes that the pending lead pigment and  lead-based  paint
litigation  is  without  merit.  Liability  that  may  result,  if  any,  cannot
reasonably be estimated.

      In 1989 and 1990,  the Housing  Authority  of New Orleans  ("HANO")  filed
third-party  complaints for indemnity and/or  contribution  against the Company,
other alleged  manufacturers  of lead pigment  (together  with the Company,  the
"pigment  manufacturers") and the Lead Industries  Association (the "LIA") in 14
actions  commenced by residents of HANO units seeking  compensatory and punitive
damages for injuries allegedly caused by lead pigment.  The actions,  which were
pending  in the  Civil  District  Court  for the  Parish  of  Orleans,  State of
Louisiana,  were  dismissed by the district  court in 1990.  Subsequently,  HANO
agreed to consolidate  all the cases and appealed.  In March 1992, the Louisiana
Court of Appeals,  Fourth  Circuit,  dismissed  HANO's  appeal as untimely  with
respect to three of these cases. With respect to the other cases included in the
appeal,  the court of appeals  reversed the lower court decision  dismissing the
cases. These cases were remanded to the District Court for further  proceedings.
In November  1994,  the District  Court granted  defendants'  motion for summary
judgment  in one of the  remaining  cases  and in June 1995 the  District  Court
granted  defendants'  motion for summary  judgment  in several of the  remaining
cases. After such grant, only two cases remain pending.

      In June 1989, a complaint  was filed in the Supreme  Court of the State of
New York,  County of New York,  against the pigment  manufacturers  and the LIA.
Plaintiffs seek damages, contribution and/or indemnity in an amount in excess of
$50 million for monitoring and abating  alleged lead paint hazards in public and
private  residential  buildings,  diagnosing  and  treating  children  allegedly
exposed to lead paint in city  buildings,  the costs of educating city residents
to the hazards of lead paint,  and liability in personal  injury actions against
the City and the  Housing  Authority  based on alleged  lead  poisoning  of city
residents (The City of New York, the New York City Housing Authority and the New
York City Health and Hospitals  Corp. v. Lead Industries  Association,  Inc., et
al., No. 89-4617). In December 1991, the court granted the defendants' motion to
dismiss claims alleging negligence and strict liability and denied the remainder
of the motion. In January 1992,  defendants appealed the denial. The Company has
answered the remaining  portions of the  complaint  denying all  allegations  of
wrongdoing, and the case is in discovery. In May 1993, the Appellate Division of
the  Supreme  Court  affirmed  the denial of the  motion to dismiss  plaintiffs'
fraud,  restitution  and  indemnification  claims.  In May 1994, the trial court
granted the

                                    -11-





defendants'  motion to dismiss the plaintiffs'  restitution and  indemnification
claims, and plaintiffs  appealed.  In June 1996, the Appellate Division reversed
the trial  court's  dismissal of  plaintiffs'  restitution  and  indemnification
claims, reinstating those claims. Defendants' motion for summary judgment on the
fraud claim was denied in August 1995;  defendants  have  appealed.  In December
1995,  defendants  moved for summary  judgment on the basis that the fraud claim
was  time-barred.  In February 1996,  the motion was denied and defendants  have
appealed. Discovery is proceeding.

      In March 1992,  the Company was served with a complaint  in  Skipworth  v.
Sherwin-Williams Co., et al. (No. 92-3069), Court of Common Pleas,  Philadelphia
County. Plaintiffs are a minor and her legal guardians seeking damages from lead
paint and pigment producers, the LIA, the Philadelphia Housing Authority and the
owners of the plaintiffs' premises for bodily injuries allegedly suffered by the
minor from lead-based paint. Plaintiffs' counsel has asserted that approximately
200 similar complaints would be served shortly,  but no such complaints have yet
been served.  In April 1994,  the court granted  defendants'  motion for summary
judgment and the dismissal  was affirmed by the Superior  Court in October 1995.
In February  1997,  the  Pennsylvania  Supreme  Court  unanimously  affirmed the
Superior Court's decision.

      In August  1992,  the  Company  was served  with an amended  complaint  in
Jackson,  et al. v. The Glidden  Co., et al.,  Court of Common  Pleas,  Cuyahoga
County,  Cleveland,  Ohio (Case No. 236835).  Plaintiffs seek  compensatory  and
punitive  damages for personal  injury caused by the  ingestion of lead,  and an
order directing  defendants to abate lead-based  paint in buildings.  Plaintiffs
purport to represent a class of similarly  situated persons throughout the State
of Ohio.  The amended  complaint  identifies 18 other  defendants  who allegedly
manufactured  lead products or lead-based  paint,  and asserts  causes of action
under theories of strict  liability,  negligence per se,  negligence,  breach of
express  and implied  warranty,  fraud,  nuisance,  restitution,  and  negligent
infliction of emotional  distress.  The complaint  asserts  several  theories of
liability including joint and several,  market share, enterprise and alternative
liability.  In October  1992,  the  Company  and the other  defendants  moved to
dismiss the complaint  with  prejudice.  In July 1993,  the court  dismissed the
complaint.  In December 1994, the Ohio Court of Appeals reversed the trial court
dismissal  and  remanded the case to the trial  court.  In July 1996,  the trial
court granted  defendants'  motion to dismiss the property damage and enterprise
liability  claims,  but  denied  the  remainder  of  the  motion.  Discovery  is
proceeding with respect to class certification.

      In November 1993,  the Company was served with a complaint in Brenner,  et
al. v. American  Cyanamid,  et al., (No.  12596-93) Supreme Court,  State of New
York, Erie County alleging injuries to two children  purportedly  caused by lead
pigment.  The  complaint  seeks $24 million in  compensatory  and $10 million in
punitive damages for alleged negligent failure to warn, strict liability,  fraud
and   misrepresentation,   concert  of  action,  civil  conspiracy,   enterprise
liability,  market share liability,  and alternative liability. In January 1994,
the Company answered the complaint, denying liability. Discovery is proceeding.


                                    -12-





      In January 1995, the Company was served with  complaints in Wright (Alvin)
and Wright (Allen) v. Lead  Industries,  et. al.,  (Nos.  94-363042 and 363043),
Circuit  Court,  Baltimore  City,  Maryland.  Plaintiffs  are two brothers  (one
deceased) who allege  injuries due to exposure to lead pigment.  The complaints,
as amended  in April  1995,  seek more than $100  million  in  compensatory  and
punitive damages for alleged strict liability, negligence, conspiracy, fraud and
unfair and  deceptive  trade  practices  claims.  In July 1995,  the trial court
granted,  in  part,  the  defendants'  motion  to  dismiss,  and  dismissed  the
plaintiffs' fraud and unfair and deceptive trade practices claims. In June 1996,
the trial court granted defendants' motions for summary judgement on plaintiffs'
conspiracy  claim,  and dismissed the Company and certain other  defendants from
the cases. In September 1996, the trial court granted the remaining  defendants'
motions for summary judgment. Plaintiffs have appealed as to all defendants.

      In November  1995,  the Company was served with the complaint in Jefferson
v. Lead Industry Association,  et. al. (No. 95-2835), filed in the U.S. District
Court for the Eastern  District  of  Louisiana.  The  complaint  asserts  claims
against the LIA and the lead pigment defendants on behalf of a putative class of
allegedly injured children in Louisiana. The complaint purports to allege claims
for strict liability, negligence, failure to warn, breach of alleged warranties,
fraud and  misrepresentation,  and  conspiracy,  and seeks  actual and  punitive
damages.  The complaint  asserts several theories of liability,  including joint
and several and market share  liability.  In June 1996,  the trial court granted
defendants'  motions to dismiss the complaint  and entered  judgment in favor of
all defendants. Plaintiffs appealed to the Fifth Circuit Court of Appeals, which
affirmed the judgment in favor of all defendants in March 1997.

      In January  1996,  the Company  was served  with a complaint  on behalf of
individual  intervenors in German,  et. al. v. Federal Home Loan Mortgage Corp.,
et. al., (U.S.  District Court,  Southern District of New York, Civil Action No.
93 Civ.  6941 (RWS)).  This class  action  lawsuit had  originally  been brought
against the City of New York and other  landlord  defendants.  The  intervenors'
complaint  alleges claims against the Company and other former  manufacturers of
lead pigment for medical monitoring,  property  abatement,  and other injunctive
relief,  based on various causes of action,  including negligent product design,
negligent  failure  to warn,  strict  liability,  fraud  and  misrepresentation,
concert  of  action,  civil  conspiracy,   enterprise  liability,  market  share
liability,   breach  of  express  and  implied  warranties,  and  nuisance.  The
intervenors  purport to  represent a class of children  and  pregnant  women who
reside  in New  York  City.  In May  1996,  the  Company  and the  other  former
manufacturers  of lead  pigments  filed  motions  to  dismiss  the  intervenors'
complaint. Class discovery is proceeding.

      In April  1996,  the  Company  was  served  with a  complaint  in Gates v.
American  Cyanamid Co., et al., (No.  I1996-2114)  Supreme  Court,  State of New
York, Erie County, an action alleging personal injury arising out of exposure to
lead  pigment.  Plaintiff  seeks  compensatory  and  punitive  damages  from the
Company,  other former lead pigment manufacturers and the LIA based on claims of
negligence,  strict  liability,  fraud,  concert  of action,  civil  conspiracy,
enterprise  liability,   market  share  liability  and  alternative   liability.
Plaintiff also asserts claims against the landlords of the apartments in which

                                    -13-





plaintiff  has lived  since  1977.  In July 1996,  the  Company  filed an answer
denying  plaintiff's  allegations  of  wrongdoing  and  liability.  Discovery is
proceeding.

      In September  1996,  the Company was served with a complaint in Ritchie v.
NL  Industries,  et al.  (U.S.  District  Court,  Northern  District  of Western
Virginia,  Civil Action No.  5:96-CV-166),  an action  originally  filed in West
Virginia  state  court on behalf  of a minor  allegedly  injured  as a result of
exposure to lead pigment.  Plaintiffs  seeks  compensatory  and punitive damages
from the Company and five other former  manufacturers  of lead pigment  based on
claims of negligence,  strict liability,  breach of warranty, fraud, conspiracy,
market  share  liability  and  alternative  liability.   In  October  1996,  the
defendants  removed  the case to federal  court and filed  motions  to  dismiss.
Plaintiffs has filed a motion to remand the case to state court. The motions are
pending.

      The Company  believes that the foregoing lead pigment  actions are without
merit  and  intends  to  continue  to deny all  allegations  of  wrongdoing  and
liability and to defend such actions vigorously.

      The Company  has filed  actions  seeking  declaratory  judgment  and other
relief against various  insurance  carriers with respect to costs of defense and
indemnity coverage for certain of its environmental and lead pigment litigation.
NL Industries,  Inc. v. Commercial  Union Insurance Cos., et al., Nos.  90-2124,
- -2125 (HLS) (District Court of New Jersey).  The action relating to lead pigment
litigation  defense costs filed in May 1990 against  Commercial  Union Insurance
Company ("Commercial Union") seeks to recover defense costs incurred in the City
of New York lead pigment case and two other cases which have since been resolved
in the Company's favor. In July 1991, the court granted the Company's motion for
summary judgment and ordered  Commercial  Union to pay the Company's  reasonable
defense  costs for such  cases.  In June  1992,  the  Company  filed an  amended
complaint  in the United  States  District  Court for the District of New Jersey
against  Commercial  Union seeking to recover costs  incurred in defending  four
additional  lead pigment  cases which have since been  resolved in the Company's
favor.  In August  1993,  the court  granted  the  Company's  motion for summary
judgment and ordered  Commercial  Union to pay the reasonable costs of defending
those cases.  In July 1994,  the court entered  judgment on the order  requiring
Commercial  Union to pay  previously-incurred  Company costs in defending  those
cases.  In  September  1995,  the U.S.  Court of Appeals  for the Third  Circuit
reversed and remanded for further  consideration the decision by the trial court
that  Commercial  Union was  obligated to pay the Company's  reasonable  defense
costs in  certain  of the lead  pigment  cases.  The  trial  court  had made its
decision  applying New Jersey law; the appeals court concluded that New York and
not New  Jersey  law  applied  and  remanded  the case to the trial  court for a
determination under New York law. On remand from the Court of Appeals, the trial
court in April 1996 granted the Company's motion for summary  judgment,  finding
that  Commercial  Union had a duty to defend the  Company in the four lead paint
cases which were the subject of the  Company's  second  amended  complaint.  The
court also  issued a partial  ruling on  Commercial  Union's  motion for summary
judgment in which it sought  allocation of defense costs and  contribution  from
the Company and two other  insurance  carriers in connection with the three lead
paint  actions on which the court had granted the  Company  summary  judgment in
1991. The court

                                    -14-





ruled that Commercial  Union is entitled to receive such  contribution  from the
Company and the two carriers,  but reserved  ruling with respect to the relative
contributions to be made by each of the parties,  including contributions by the
Company  that  may  be  required  with  respect  to  periods  in  which  it  was
self-insured and contributions from one carrier which were reinsured by a former
subsidiary  of the  Company,  the  reinsurance  costs of which the  Company  may
ultimately be required to bear. Other than granting motions for summary judgment
brought by two excess liability insurance  carriers,  which contended that their
policies contained absolute pollution  exclusion  language,  and certain summary
judgment  motions  regarding  policy  periods,  the court has not made any final
rulings on defense  costs or indemnity  coverage  with respect to the  Company's
pending  environmental  litigation.  The Court has not made any final  ruling on
indemnity coverage in the lead pigment litigation. No trial dates have been set.
Other than rulings to date, the issue of whether insurance  coverage for defense
costs or  indemnity  or both will be found to exist  depends  upon a variety  of
factors,  and there can be no assurance that such insurance  coverage will exist
in  other  cases.  The  Company  has  not  considered  any  potential  insurance
recoveries for lead pigment or environmental  litigation in determining  related
accruals.

  Environmental matters and litigation

      The  Company  has been named as a  defendant,  PRP,  or both,  pursuant to
CERCLA and  similar  state laws in  approximately  75  governmental  and private
actions  associated with waste disposal sites,  mining  locations and facilities
currently  or  previously  owned,  operated  or  used  by  the  Company,  or its
subsidiaries,  or their  predecessors,  certain  of which are on the U.S.  EPA's
Superfund  National  Priorities List or similar state lists.  These  proceedings
seek cleanup costs,  damages for personal  injury or property  damage,  or both.
Certain of these proceedings  involve claims for substantial  amounts.  Although
the Company may be jointly and severally liable for such costs, in most cases it
is only one of a number of PRPs who may also be jointly and severally liable.

      The extent of CERCLA liability  cannot  accurately be determined until the
Remedial  Investigation and Feasibility Study ("RIFS") is complete, the U.S. EPA
issues a record of decision and costs are  allocated  among PRPs.  The extent of
liability under analogous state cleanup  statutes and for common law equivalents
are  subject to similar  uncertainties.  The Company  believes  it has  provided
adequate  accruals for reasonably  estimable  costs for CERCLA matters and other
environmental  liabilities.  At December 31, 1996,  the Company had accrued $113
million for those  environmental  matters which are  reasonably  estimable.  The
Company  determines the amount of accrual on a quarterly  basis by analyzing and
estimating the range of possible costs to the Company. Such costs include, among
other things, remedial investigations,  monitoring,  studies,  clean-up, removal
and remediation. During the first quarter of 1997, the Company's accrual will be
increased  to include  legal fees and other  costs of  managing  and  monitoring
environmental  remediation  sites as  required  by the  adoption  of the AICPA's
Statement of Position 96-1, "Environmental  Remediation Liabilities." See Note 2
to the  Consolidated  Financial  Statements.  It is not possible to estimate the
range of costs for certain  sites.  The Company has estimated that the upper end
of the range of reasonably  possible costs to the Company for sites for which it
is possible to estimate  costs is  approximately  $160  million.  The  Company's
estimate of such liability has not been discounted to present value and the

                                    -15-





Company has not recognized any potential insurance recoveries.  No assurance can
be given that actual costs will not exceed either  accrued  amounts or the upper
end of the range for sites for which  estimates have been made, and no assurance
can be given that costs will not be incurred  with  respect to sites as to which
no estimate presently can be made. The imposition of more stringent standards or
requirements  under  environmental  laws or  regulations,  new  developments  or
changes respecting site cleanup costs or allocation of such costs among PRPs, or
a determination  that the Company is potentially  responsible for the release of
hazardous  substances at other sites could result in  expenditures  in excess of
amounts  currently  estimated  by the Company to be required  for such  matters.
Further,  there can be no assurance that additional  environmental  matters will
not arise in the future. More detailed descriptions of certain legal proceedings
relating to environmental matters are set forth below.

      At  Pedricktown,  the U.S. EPA divided the site into two  operable  units.
Operable unit one addresses  contaminated ground water, surface water, soils and
stream  sediments.  In July 1994, the U.S. EPA issued the Record of Decision for
operable unit one. The U.S. EPA estimates the cost to complete operable unit one
is $18.7 million.  In May 1996, certain PRPs, but not the Company,  entered into
an administrative consent order with the U.S. EPA to perform the remedial design
phase of operable unit one. In addition, the U.S. EPA incurred past costs in the
estimated  amount of $5 million.  The U.S.  EPA issued an order with  respect to
operable  unit two in March  1992 to the  Company  and 30 other  PRPs  directing
immediate removal activities  including the cleanup of waste,  surface water and
building  surfaces.  The Company has complied with the order,  and the work with
respect to operable  unit two is completed.  The Company has paid  approximately
50% of operable unit two costs, or $2.5 million.

      At Granite City, the RIFS is complete, and in 1990 the U.S. EPA selected a
remedy estimated at that time to cost  approximately $28 million.  In July 1991,
the United  States filed an action in the U.S.  District  Court for the Southern
District of Illinois against the Company and others (United States of America v.
NL  Industries,  Inc., et al., Civ. No. 91-CV 00578) with respect to the Granite
City smelter.  The complaint seeks injunctive relief to compel the defendants to
comply with an  administrative  order issued  pursuant to CERCLA,  and fines and
treble damages for the alleged failure to comply with the order. The Company and
the other parties did not implement the order believing that the remedy selected
by the U.S.  EPA was  invalid,  arbitrary,  capricious  and was not  selected in
accordance  with law.  The  complaint  also seeks  recovery  of past costs and a
declaration that the defendants are liable for future costs. Although the action
was filed against the Company and ten other defendants, there are 330 other PRPs
who have  been  notified  by the U.S.  EPA.  Some of those  notified  were  also
respondents to the  administrative  order. In February 1992, the court entered a
case  management  order  directing  that the remedy  issues be tried  before the
liability  aspects are presented.  In September  1995, the U.S. EPA released its
amended decision  selecting  cleanup remedies for the Granite City site. At that
time,  the cost of the  remedies  selected by the U.S.  EPA  aggregated,  in its
estimation,  $40.8 million to $67.8 million,  although its decision  stated that
the higher amount was not considered to be representative of expected costs. The
Company  presently is challenging  portions of the U.S.  EPA's  selection of the
remedy.  The U.S. EPA's current  estimate for completion of the cleanup is $24.3
million,  and in January  1997,  the  Company  was  informed  that the U.S.  EPA
incurred

                                    -16-





cleanup and other past costs  approximating  $30 million.  There is currently no
allocation among the PRPs for these costs.

      Having  completed the RIFS at Portland,  the Company  conducted  predesign
studies to explore the viability of the U.S. EPA's selected remedy pursuant to a
June 1989 consent decree  captioned U.S. v. NL  Industries,  Inc.,  Civ. No. 89-
408, United States District Court for the District of Oregon.  Subsequent to the
completion of the predesign  studies,  the U.S. EPA issued  notices of potential
liability to  approximately  20 PRPs,  including the Company,  directing them to
perform the remedy,  which was  initially  estimated to cost  approximately  $17
million,  exclusive  of  administrative  and overhead  costs and any  additional
costs, for the disposition of recycled materials from the site. In January 1992,
the U.S.  EPA issued  unilateral  administrative  orders to the  Company and six
other PRPs directing the  performance  of the remedy.  The Company and the other
PRPs  commenced  performance  of the  remedy.  In  August  1994,  the  U.S.  EPA
authorized  the Company and the other PRPs to cease  performing  most aspects of
the  selected  remedy.  The U.S.  EPA has issued a proposed  Record of  Decision
Amendment  changing  portions of the cleanup  remedy  selected for the site. The
U.S. EPA  currently  estimates  the cost of the  proposed  remedy to be from $10
million to $13 million.  Pursuant to an interim allocation,  the Company's share
of remedial  costs is  approximately  50%. In November  1991,  Gould,  Inc., the
current owner of the site, filed an action,  Gould Inc. v. NL Industries,  Inc.,
No. 91-1091,  United States  District Court for the District of Oregon,  against
the Company for damages for alleged fraud in the sale of the smelter, rescission
of the sale,  past CERCLA response costs and a declaratory  judgment  allocating
future response costs and punitive damages.  The court granted Gould's motion to
amend the complaint to add additional  defendants  (adjoining current and former
landowners and generators). The amended complaint deletes the fraud and punitive
damages claims asserted  against NL; thus, the pending action is essentially one
for  reallocation of past and future cleanup costs.  Discovery is proceeding.  A
trial  date has been set for  September  1997.  The  Company  and the other PRPs
performing  the cleanup have reached  settlement  in principle  with many of the
generators and adjoining landowner defendants.

      The Company and other PRPs entered into an  administrative  consent  order
with the U.S. EPA requiring the  performance  of a RIFS at two sites in Cherokee
County,  Kansas,  where the Company and others  formerly  mined lead and zinc. A
former  subsidiary of the Company mined at the Baxter Springs subsite,  where it
is the largest  viable PRP. The final RIFS was  submitted to the U.S. EPA in May
1993.  In August 1994,  the U.S. EPA issued its proposed plan for the cleanup of
the Baxter Springs and Treece sites in Cherokee  County.  The proposed remedy is
estimated by U.S. EPA to cost $6 million.

      In January  1989,  the State of  Illinois  brought an action  against  the
Company and several other subsequent owners and operators of the former plant in
Chicago, Illinois (People of the State of Illinois v. NL Industries, et al., No.
88-CH-11618,  Circuit Court, Cook County).  The complaint seeks recovery of $2.3
million of cleanup  costs  expended  by the  Illinois  Environmental  Protection
Agency, plus penalties and treble damages. In October 1992, the Supreme Court of
Illinois reversed the Appellate  Division,  which had affirmed the trial court's
earlier  dismissal  of  the  complaint,   and  remanded  the  case  for  further
proceedings. In December 1993, the trial court denied the State's petition to

                                    -17-





reinstate the  complaint,  and dismissed  the case with  prejudice.  In November
1996, the appeals court reversed the dismissal. The U.S. EPA has issued an order
to the  Company to perform a removal  action at the  Company's  former  facility
involved in the State of Illinois case. The Company is complying with the order.


      In 1980, the State of New York commenced litigation against the Company in
connection with the operation of a plant in Colonie,  New York formerly owned by
the Company. Flacke v. NL Industries,  Inc., No. 1842-80 ("Flacke I") and Flacke
v. Federal Insurance Company and NL Industries, Inc., No. 3131-92 ("Flacke II"),
New York Supreme  Court,  Albany  County.  The plant  manufactured  military and
civilian products from depleted uranium and was acquired from the Company by the
U.S.  Department of Energy ("DOE") in 1984. Flacke I seeks penalties for alleged
violations of New York's Environmental  Conservation Law, and of a consent order
entered into to resolve these alleged violations.  Flacke II seeks forfeiture of
a $200,000  surety  bond  posted in  connection  with the  consent  order,  plus
interest from February 1980. The Company denied  liability in both actions.  The
litigation  had been inactive from 1984 until July 1993 when the State moved for
partial summary judgment for approximately $1.5 million on certain of its claims
in Flacke I and for summary  judgment in Flacke II. In January 1994, the Company
cross-moved for summary judgment in Flacke I and Flacke II. All summary judgment
motions have been denied. The Company has reached a settlement in principle with
the State.

      Residents  in the  vicinity  of the  Company's  former  Philadelphia  lead
chemicals  plant  commenced a class  action  allegedly  comprised  of over 7,500
individuals seeking medical monitoring and damages allegedly caused by emissions
from the plant.  Wagner, et al. v. Anzon, Inc. and NL Industries,  Inc., No. 87-
4420,  Court  of  Common  Pleas,   Philadelphia  County.  The  complaint  sought
compensatory  and punitive damages from the Company and the current owner of the
plant, and alleged causes of action for, among other things, negligence,  strict
liability,  and nuisance.  A class was certified to include persons who resided,
owned or rented property,  or who work or have worked within up to approximately
three-quarters  of a mile from the plant  from 1960  through  the  present.  The
Company answered the complaint,  denying  liability.  In December 1994, the jury
returned  a  verdict  in  favor  of  the  Company.  Plaintiffs  appealed  to the
Pennsylvania  Superior Court,  requesting a new trial and in September 1996, the
Superior Court affirmed the judgment in favor of the Company.  In December 1996,
plaintiffs filed a petition for allowance of appeal to the Pennsylvania  Supreme
Court.  Plaintiffs'  petition  is  pending.  Residents  also filed  consolidated
actions  in the  United  States  District  Court  for the  Eastern  District  of
Pennsylvania,  Shinozaki  v. Anzon,  Inc. and Wagner and Antczak v. Anzon and NL
Industries,  Inc. Nos. 87-3441,  87-3502,  87-4137 and 87-5150. The consolidated
action is a putative  class action  seeking  CERCLA  response  costs,  including
cleanup and medical  monitoring,  declaratory  and  injunctive  relief and civil
penalties for alleged  violations of the Resource  Conservation and Recovery Act
("RCRA"),  and also asserting  pendent  common law claims for strict  liability,
trespass,  nuisance and punitive  damages.  The court  dismissed  the common law
claims without prejudice,  dismissed two of the three RCRA claims as against the
Company  with  prejudice,  and stayed the case  pending the outcome of the state
court litigation.


                                    -18-





      In July 1991, a complaint  was filed in the United States  District  Court
for the Central  District of California,  United States of America v. Peter Gull
and NL Industries,  Inc.,  Civ. No. 91-4098,  seeking  recovery of $2 million in
costs  incurred  by the United  States in  response  to the  alleged  release of
hazardous  substances  into the  environment  from a facility  located in Norco,
California,  treble  damages and $1.75  million in penalties  for the  Company's
alleged  failure to comply with the U.S. EPA's  administrative  order No. 88-13.
The order, which alleged that the Company arranged for the treatment or disposal
of materials  at the Norco site,  directed  the  immediate  removal of hazardous
substances from the site. The Company carried out a portion of the remedy at the
Norco site, but did not complete the ordered activities because it believed they
were in  conflict  with  California  law.  The court  ruled that the Company was
liable for approximately  $2.7 million in response costs plus approximately $3.6
million in penalties  for failure to comply with the  administrative  order.  In
April 1994,  the court  entered  final  judgment in this  matter  directing  the
Company to pay $6.3 million plus  interest.  Both the Company and the government
have appealed.  In August 1994, this matter was referred to mediation,  which is
pending.

      At a municipal and industrial  waste  disposal site in Batavia,  New York,
the  Company  and six others  have been  identified  as PRPs.  The U.S.  EPA has
divided the site into two operable units. Pursuant to an administrative  consent
order entered into with the U.S. EPA, the Company  conducted a RIFS for operable
unit one, the closure of the industrial  waste disposal section of the landfill.
The Company's RIFS costs were  approximately $2 million.  In June 1995, the U.S.
EPA issued the record of decision for operable  unit one,  which is estimated by
the U.S. EPA to cost  approximately  $12.3 million.  In September 1995, the U.S.
EPA and certain  PRPs entered  into an  administrative  order on consent for the
remedial  design phase of the remedy for operable  unit one and the design phase
is  proceeding.  The Company and other PRPs entered into an interim cost sharing
arrangement  for this phase of work.  With respect to the second  operable unit,
the extension of the municipal water supply, the U.S. EPA estimated the costs at
$1.2 million plus annual  operation and maintenance  costs.  The Company and the
other PRPs are  performing the work  comprising  operable unit two. The U.S. EPA
has also demanded approximately $.9 million in past costs from the PRPs.

      See Item 1.  "Business - Regulatory and Environmental Matters."

  Other litigation

      Rhodes,  et al. v. ACF  Industries,  Inc., et al. (Circuit Court of Putnam
County,  West Virginia,  No. 95-C-261).  Twelve  plaintiffs  brought this action
against the Company and various other defendants in July 1995. Plaintiffs allege
that they were employed by demolition and disposal  contractors,  and claim that
as a result of the  defendants'  negligence they were exposed to asbestos during
demolition and disposal of materials from defendants' premises in West Virginia.
Plaintiffs allege personal injuries and seek compensatory damages totaling $18.5
million and punitive  damages  totaling $55.5 million.  The Company has filed an
answer denying plaintiffs' allegations. Discovery is proceeding.


                                    -19-





      The  Company has been named as a defendant  in various  lawsuits  alleging
personal  injuries  as a result of  exposure  to  asbestos  in  connection  with
formerly-owned  operations.  Various of these actions remain  pending.  One such
case, In re:  Monongalia  Mass II,  (Circuit  Court of Monongalia  County,  West
Virginia,   Nos.  93-C-362,   et  al.),  involves  the  consolidated  claims  of
approximately  3,100  plaintiffs.  The Company  intends to defend these  matters
vigorously.

      Plaintiff brought the complaint in Frank D. Seinfeld v. Harold C. Simmons,
et al.  (Superior  Court of New York,  Bergen  County,  Chancery  Division,  No.
C-336-96) in September 1996 on behalf of himself and derivatively,  on behalf of
NL,  against the Company,  Valhi and certain  current and former  members of the
Company's Board of Directors.  The complaint alleges,  among other things,  that
the Company's  purchase of shares in an August 1991 "Dutch auction" tender offer
was an unfair and wasteful expenditure of the Company's funds that constituted a
breach  of the  defendants'  fiduciary  duties  to the  Company's  shareholders.
Plaintiff  seeks,  among  other  things,  to rescind the  Company's  purchase of
approximately 10.9 million shares of its common stock from Valhi pursuant to the
Dutch  auction,  and plaintiff has stated that damages  sought are $149 million.
The Company and the other defendants have answered the complaint and have denied
all allegations of wrongdoing.  The Company believes,  and understands that each
of the other  defendants  believes,  that the  complaint is without  merit.  The
Company  intends,  and believes that each of the other  defendants  intends,  to
defend the action vigorously. Trial is scheduled to begin in November 1997.

      The Company is also involved in various other environmental,  contractual,
product  liability  and other claims and disputes  incidental to its present and
former businesses, and the disposition of past properties and former businesses.

-22- (1) EBITDA, as presented, represents operating income less corporate expense, net, plus depreciation, depletion and amortization. EBITDA is presented as a supplement to the Company's operating income and cash flow from operations because the Company believes that EBITDA is a widely accepted financial indicator of cash flows and the ability to service debt. EBITDA should not be considered as an alternative to, or more meaningful than, generally accepted accounting principles ("GAAP") operating income or net income as an indicator of the Company's operating performance, or GAAP cash flows from operating, investing and financing activities as a measure of liquidity. EBITDA is not intended to depict funds available for reinvestment or other discretionary uses, as the Company has significant debt requirements and other commitments. Investors should consider certain factors in evaluating the Company's EBITDA, including interest expense, income taxes, noncash income and expense items, changes in assets and liabilities, capital expenditures, investments in joint ventures and other items included in GAAP cash flows as well as future debt repayment requirements and other commitments, including those described in Notes 10, 13 and 17 to the Consolidated Financial Statements. The Company believes that the trend of its EBITDA is consistent with the trend of its GAAP operating income. See "Management's Discussion and Analysis" for a discussion of operating income and cash flows during the last three years and the Company's outlook. EBITDA as a measure of a company's performance may not be comparable to other companies, unless substantially all companies and analysts determine EBITDA as computed and presented herein. (2) Net debt represents notes payable and long-term debt less cash, cash equivalents (including restricted cash) and current marketable securities. (3) Interest expense, net represents interest expense less general corporate interest and dividend income. (4) Cash interest expense, net represents interest expense, net less noncash interest expense (deferred interest expense on the Senior Secured Discount Notes and amortization of deferred financing costs). -23- ITEM 7. MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS RESULTS OF OPERATIONS General The Company's operations are conducted in two business segments - TiO2 conducted by Kronos and specialty chemicals conducted by Rheox. As discussed below, TiO2 selling prices increased during 1994 and the first half of 1995, but declined in the last half of 1995 and during 1996. Kronos' operating income and margins improved during 1995, but declined in 1996. Many factors influence TiO2 pricing levels, including industry capacity, worldwide demand growth and customer inventory levels and purchasing decisions. Kronos believes the decline in prices in 1996 was due, in part, to the impact of recent debottlenecking projects increasing capacity, TiO2 customers reducing inventory levels in a period of declining prices, and greater competition for sales volume with more industry capacity available. Kronos believes that the TiO2 industry has long-term growth potential, as discussed in "Item 1. Business - - Kronos - Industry" and "Competition." Net sales and operating income
Years ended December 31, % Change ------------------------------ ---------------- 1994 1995 1996 1995-94 1996-95 -------- -------- -------- ------- ------- (In millions) Net sales: Kronos .................... $ 770.1 $ 894.1 $ 851.2 +16% -5% -------- -------- -------- Rheox ..................... 117.9 129.8 134.9 +10% +4% $ 888.0 $1,023.9 $ 986.1 +15% -4% ======== ======== ======== Operating income: Kronos .................... $ 80.6 $ 161.2 $ 71.6 +100% -56% Rheox ..................... 30.8 38.5 41.8 +25% +8% -------- -------- -------- $ 111.4 $ 199.7 $ 113.4 +79% -43% ======== ======== ======== Percent change in TiO2: Sales volume .............. -3% +6% Average selling prices (in billing currencies) .. +15% -9%
Kronos' operating income in 1996 was lower than 1995 primarily due to lower average TiO2 selling prices, partially offset by higher sales volumes. In billing currency terms, Kronos' 1996 average TiO2 selling prices were approximately 9% lower than in 1995. Average selling prices in the fourth quarter of 1996 were 17% lower than the fourth quarter of 1995 and were 3% lower than the third quarter of 1996. Selling prices at the end of 1996 were 17% below year-end 1995 levels, 8% below the average for 1996 and were 1% below the average selling prices during the fourth quarter of 1996. The improvement in Kronos' 1995 results over 1994 was primarily due to 15% higher average TiO2 selling -24- prices and higher TiO2 production volumes, partially offset by lower TiO2 sales volumes. Kronos' cost of sales in 1996 was higher than 1995 due to higher sales volumes and higher unit costs, primarily due to lower production levels. Kronos' costs of sales in 1995 was higher than 1994 due to slightly higher manufacturing costs, partially offset by lower sales volumes. As a percentage of net sales, cost of sales increased in 1996 and decreased in 1995 primarily due to the impact on net sales of changes in the average selling price during the respective years. Kronos' selling, general and administrative expenses declined in 1996 from the previous year, as a result of continuing cost containment efforts, while 1995's expense was higher than 1994 due to the unfavorable effect of changes in currency exchange rates. Record sales volume of 388,000 metric tons of TiO2 in 1996 increased 6% compared to 1995, with improvements in all major markets, including a 10% increase in North America. Sales volumes in the second half of 1996 were 16% higher than the same period in 1995. In response to soft demand in the first half of 1996 and its high inventory levels at the end of 1995, Kronos curtailed production rates in early 1996. As demand increased during the last half of 1996 and inventories declined, Kronos' production rates were increased to near full capacity in late 1996 and the average capacity utilization was 95% for the year. Kronos' production rates were 94% of its capacity in 1994 and at full capacity in 1995. Approximately one-half of Kronos' 1996 TiO2 sales, by volume, were attributable to markets in Europe with approximately 37% attributable to North America and the balance to other regions. Demand, supply and pricing of TiO2 have historically been cyclical. Kronos anticipates its TiO2 operating margins will begin to improve in the second quarter of 1997 as the impact of recently-announced TiO2 price increases takes effect; however, Kronos expects its 1997 operating income will be below that of 1996, primarily because of lower anticipated average TiO2 prices for 1997 compared to 1996 and lower technology fee income. Demand for TiO2 in 1996 increased over 1995 and Kronos expects demand to remain strong in 1997. Kronos believes continued growth in demand should result in significant improvement in average selling prices over the longer term. Rheox's operating income improved in 1996 compared to 1995 due to 5% higher sales volumes, lower selling, general and administrative expenses and a $2.7 million gain related to the curtailment of certain U.S. employee pension benefits, partially offset by slightly higher manufacturing costs. Operating income increased in 1995 over 1994 due to 5% higher sales volumes and higher average selling prices, partially offset by higher raw material costs. Rheox's cost of sales increased in 1995 and 1996 over the respective prior year primarily due to higher sales volumes, and cost of sales as a percentage of net sales were approximately the same level in 1994, 1995 and 1996. Selling, general and administrative expenses decreased slightly in 1996 compared to 1995 due to lower variable compensation expense, and selling, general and administrative expenses in 1995 approximated 1994 amounts. -25- The Company has substantial operations and assets located outside the United States (principally Germany, Norway, Belgium and Canada). The U.S. dollar value of the Company's foreign sales and operating costs is subject to currency exchange rate fluctuations which may slightly impact reported earnings and may affect the comparability of period-to-period operating results. A significant amount of the Company's sales are denominated in currencies other than the U.S. dollar (61% in 1996), principally major European currencies and the Canadian dollar. Certain purchases of raw materials, primarily titanium-containing feedstocks, are denominated in U.S. dollars, while labor and other production costs are primarily denominated in local currencies. Fluctuations in the value of the U.S. dollar relative to other currencies decreased 1996 sales by $14 million compared to 1995 and increased 1995 sales by $54 million compared to 1994. General corporate The following table sets forth certain information regarding general corporate income (expense).

Securities earnings fluctuate in part based upon the amount of funds invested and yields thereon. Corporate expenses, net in 1996 were lower than 1995 due to lower provisions for environmental remediation cost. Corporate expenses, net were significantly lower in 1995 compared to 1994 due to lower provisions for environmental remediation and litigation costs. The Company expects corporate expenses, net in 1997 will exceed that of 1996, primarily due to approximately $30 million of additional environmental remediation accruals related to the adoption of a new accounting standard. See Note 2 to the Consolidated Financial Statements. Interest expense Interest expense in 1996 declined compared to 1995 principally due to lower interest rates on variable rate debt, principally Kronos' Deutsche mark-denominated debt, partially offset by higher levels of such DM-denominated debt. Interest expense in 1995 declined compared to 1994 due to lower levels of debt, principally DM-denominated debt, and lower interest rates on such DM-denominated debt. In January 1997, the Company refinanced certain U.S. debt and prepaid certain DM-denominated debt, as discussed in "Liquidity and Capital Resources," and expects its interest expense will be higher in 1997 compared to 1996 as a result of higher anticipated interest rates and average debt levels. -26- Provision for income taxes The principal reasons for the difference between the U.S. federal statutory income tax rates and the Company's effective income tax rates are explained in Note 13 to the Consolidated Financial Statements. The Company's operations are conducted on a worldwide basis and the geographic mix of income can significantly impact the Company's effective income tax rate. In 1994 and 1996, the geographic mix of income, including losses in certain jurisdictions for which no current refund was available and recognition of a deferred tax asset was not considered appropriate, contributed to the Company's effective tax rate varying from a normally-expected rate. Due to the Company's higher U.S. earnings before taxes in 1995, the Company's valuation allowance was reduced by approximately $10 million due to a change in estimate of the future tax benefit of certain U.S. tax credits which the Company believes satisfies the "more-likely-than-not" recognition criteria. During 1995, the Company also recorded deferred tax benefits of $6.6 million due to the reduction in dividend withholding tax rates pursuant to ratification of the U.S./Canada income tax treaty. The Company's deferred income tax status at December 31, 1996 is discussed in "Liquidity and Capital Resources." LIQUIDITY AND CAPITAL RESOURCES The Company's consolidated cash flows provided by operating, investing and financing activities for each of the past three years are presented below.

The TiO2 industry is cyclical and changes in economic conditions within the industry significantly impact the earnings and operating cash flows of the Company. During 1996, declining TiO2 selling prices unfavorably impacted Kronos' operating income and cash flows from operations compared to 1995. Average selling prices began a downward trend in the last half of 1995 and continued throughout 1996. The Company expects prices will begin to increase in the second quarter of 1997; however, no assurance can be given that price trends will conform to the Company's expectations and future cash flows will be adversely affected should price trends be lower than the Company's expectations. Changes in the Company's inventories, receivables and payables (excluding the effect of currency translation) also contributed to the cash provided by operations in 1994 and 1996; however, such changes used cash in 1995 primarily due to increased inventory levels. In 1994 and 1995, net proceeds of $15 million and $26 million, respectively, from the sale of trading securities are components of the cash provided from operations. Certain German income tax refunds and -27- payments, discussed below, significantly increased cash flows from operating activities during 1994 and decreased cash flows from operating activities in 1996. The Company's capital expenditures during the past three years include an aggregate of $67 million ($26 million in 1996) for the Company's ongoing environmental protection and compliance programs, including a Canadian waste acid neutralization facility, a Norwegian onshore tailings disposal system and German and Norwegian off-gas desulfurization systems. The Company's estimated 1997 and 1998 capital expenditures are $35 million and $36 million, respectively, and include $3 million and $5 million, respectively, in the area of environmental protection and compliance primarily related to the off-gas desulfurization systems. The Company spent $9 million in 1995, $18 million in 1996 and plans to spend an additional $8 million in 1997 in capital expenditures related to a debottlenecking project at its Leverkusen, Germany chloride-process TiO2 facility that is expected to increase the Company's worldwide annual attainable production to approximately 410,000 metric tons in 1998. Capital expenditures of the manufacturing joint venture are not included in the Company's capital expenditures. Rheox acquired the minority interests of certain of its non-U.S. subsidiaries for $5.2 million in 1996. In 1996, the Company borrowed DM 144 million ($96 million when borrowed) under its DM credit facility and used DM 49 million ($32 million) to fund the German tax settlement payments described below, and used the remainder of the proceeds primarily to fund operations. Repayments of indebtedness in 1996 included payments of $23 million on the Rheox bank term loan, $15 million in payments on the joint venture term loan and DM 16 million ($10 million when repaid) in payments on DM-denominated notes payable. Net repayments of indebtedness in 1995 included $30 million in payments on the Rheox bank term loan and $15 million in payments on the joint venture term loan. In addition, the Company borrowed a net DM 56 million ($40 million when borrowed) under DM-denominated short-term credit lines. In 1994, the Company borrowed DM 75 million ($45 million when borrowed) under the DM credit facility, and repayments of indebtedness included DM 225 million ($140 million when paid) in payments on the DM credit facility, $15 million in payments on the Rheox bank term loan and $15 million in payments on the joint venture term loan. In order to improve its near-term liquidity, during January 1997, the Company refinanced its Rheox subsidiary, obtaining a net $125 million of new long-term financing. The net proceeds, along with other available funds, were used to prepay DM 207 million ($127 million when paid) of the Company's DM term loan and to repay DM 43 million ($26 million when paid) of the Company's DM revolving credit facility, leaving DM 130 million ($80 million) available for borrowing at January 31, 1997. As a result of the refinancing and prepayment, the Company's aggregate scheduled debt payments for 1997 and 1998 decreased by $103 million ($64 million in 1997 and $39 million in 1998). In connection with the prepayment, the Company and its lenders modified certain financial covenants of the DM credit agreement and NL guaranteed the facility. At December 31, 1996, the Company had cash and cash equivalents aggregating $114 million (44% held by non-U.S. subsidiaries) including restricted cash and cash equivalents of $11 million. At December 31, 1996, after giving pro forma -28- effect for the refinancing discussed above, the Company had cash and cash equivalents aggregating $87 million and the Company's subsidiaries had $9 million and $102 million available for borrowing under U.S. and non-U.S. credit facilities, respectively. At December 31, 1996, the Company had complied with, or had obtained waivers for, all financial covenants governing its debt agreements. Dividends paid during 1996 totaled $15.3 million. No dividends were paid in 1994 or 1995. In October 1996, the Company's Board of Directors suspended the Company's quarterly dividend and the Company is currently unable to pay dividends due to certain restrictions under the indentures of the Senior Notes. Based upon the Company's expectations for the TiO2 industry and anticipated demands on the Company's cash resources as discussed herein, the Company expects to have sufficient liquidity to meet its near-term obligations including operations, capital expenditures and debt service. To the extent that actual developments differ from Company's expectations, the Company's liquidity could be adversely affected. Certain of the Company's income tax returns in various U.S. and non-U.S. jurisdictions are being examined and tax authorities have proposed or may propose tax deficiencies. During 1994, the German tax authorities withdrew certain proposed tax deficiencies of DM 100 million and remitted tax refunds aggregating DM 225 million ($136 million when received), including interest, on a tentative basis while examination of the Company's German income tax returns continued. The Company subsequently reached an agreement with the German tax authorities regarding such examinations which resolved certain significant tax contingencies for years through 1990. The Company received final assessments and paid certain tax deficiencies of approximately DM 50 million ($32 million), including interest, in settlement of these issues in 1996. The Company considers the agreement to be a favorable resolution of the contingencies and the payment was within previously-accrued amounts for such matters. Certain other German tax contingencies remain outstanding and will continue to be litigated. Although the Company believes that it will ultimately prevail in the litigation, the Company has granted a DM 100 million ($64 million at December 31, 1996) lien on its Nordenham, Germany TiO2 plant in favor of the German tax authorities until the litigation is resolved. No assurances can be given that this litigation will be resolved in the Company's favor in view of the inherent uncertainties involved in court rulings. The Company believes that it has adequately provided accruals for additional income taxes and related interest expense which may ultimately result from all such examinations and believes that the ultimate disposition of such examinations should not have a material adverse effect on the Company's consolidated financial position, results of operations or liquidity. At December 31, 1996, the Company had net deferred tax liabilities of $152 million. The Company operates in numerous tax jurisdictions, in certain of which it has temporary differences that net to deferred tax assets (before valuation allowance). The Company has provided a deferred tax valuation allowance of $207 million at December 31, 1996, principally related to the U.S. and Germany, -29- partially offsetting deferred tax assets which the Company believes do not currently meet the "more-likely-than-not" recognition criteria. In addition to the chemicals businesses conducted through Kronos and Rheox, the Company also has certain interests and associated liabilities relating to certain discontinued or divested businesses and other holdings of marketable equity securities including securities issued by Valhi and other Contran subsidiaries. The Company has been named as a defendant, PRP, or both, in a number of legal proceedings associated with environmental matters, including waste disposal sites, mining locations and facilities currently or previously owned, operated or used by the Company, certain of which are on the U.S. EPA's Superfund National Priorities List or similar state lists. On a quarterly basis, the Company evaluates the potential range of its liability at sites where it has been named as a PRP or defendant. The Company believes it has adequate accruals for reasonably estimable costs of such matters, but the Company's ultimate liability may be affected by a number of factors, including changes in remedial alternatives and costs and the allocation of such costs among PRPs. The Company is also a defendant in a number of legal proceedings seeking damages for personal injury and property damage arising out of the sale of lead pigments and lead-based paints. There is no assurance that the Company will not incur future liability in respect of this pending litigation in view of the inherent uncertainties involved in court and jury rulings in pending and possible future cases. However, based on, among other things, the results of such litigation to date, the Company believes that the pending lead pigment and paint litigation is without merit. The Company has not accrued any amounts for such pending litigation. Liability that may result, if any, cannot reasonably be estimated. The Company currently believes the disposition of all claims and disputes, individually or in the aggregate, should not have a material adverse effect on the Company's consolidated financial position, results of operations or liquidity. There can be no assurance that additional matters of these types will not arise in the future. See Item 3. "Legal Proceedings" and Note 17 to the Consolidated Financial Statements. As discussed above, the Company has substantial operations located outside the United States for which the functional currency is not the U.S. dollar. As a result, the reported amount of the Company's assets and liabilities related to its non-U.S. operations, and therefore the Company's consolidated net assets, will fluctuate based upon changes in currency exchange rates. The carrying value of the Company's net investment in its German operations is a net liability due principally to its DM credit facility, while its net investment in its other non-U.S. operations are net assets. The Company periodically evaluates its liquidity requirements, alternative uses of capital, capital needs and availability of resources in view of, among other things, its debt service and capital expenditure requirements and estimated future operating cash flows. As a result of this process, the Company in the past has sought and in the future may seek to reduce, refinance, repurchase or restructure indebtedness, raise additional capital, issue additional securities, modify its dividend policy, restructure ownership interests, sell interests in subsidiaries or other assets, or take a combination of such steps or other steps -30- to manage its liquidity and capital resources. In the normal course of its business, the Company may review opportunities for the acquisition, divestiture, joint venture or other business combinations in the chemicals industry. In the event of any such transaction, the Company may consider using available cash, issuing equity securities or increasing its indebtedness to the extent permitted by the agreements governing the Company's existing debt.

See accompanying notes to consolidated financial statements. F-9 NL INDUSTRIES, INC. AND SUBSIDIARIES NOTES TO CONSOLIDATED FINANCIAL STATEMENTS Note 1 - Organization and basis of presentation: NL Industries, Inc. conducts its operations primarily through its wholly- owned subsidiaries, Kronos, Inc. (titanium dioxide pigments or "TiO2") and Rheox, Inc. (specialty chemicals). Valhi, Inc. and Tremont Corporation, each affiliates of Contran Corporation, hold 56% and 18%, respectively, of NL's outstanding common stock. Contran holds, directly or through subsidiaries, approximately 91% of Valhi's and 44% of Tremont's outstanding common stock. Substantially all of Contran's outstanding voting stock is held by trusts established for the benefit of the children and grandchildren of Harold C. Simmons, of which Mr. Simmons is the sole trustee. Mr. Simmons, the Chairman of the Board of NL and the Chairman of the Board, President, and Chief Executive Officer of Contran and Valhi and a director of Tremont, may be deemed to control each of such companies. Note 2 - Summary of significant accounting policies: Principles of consolidation and management's estimates The accompanying consolidated financial statements include the accounts of NL and its majority-owned subsidiaries (collectively, the "Company"). All material intercompany accounts and balances have been eliminated. The preparation of financial statements in conformity with generally accepted accounting principles requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements, and the reported amount of revenues and expenses during the reporting period. Ultimate actual results may in some instances differ from previously estimated amounts. Translation of foreign currencies Assets and liabilities of subsidiaries whose functional currency is deemed to be other than the U.S. dollar are translated at year-end rates of exchange and revenues and expenses are translated at weighted average exchange rates prevailing during the year. Resulting translation adjustments and the related income tax effects are accumulated in the currency translation adjustment component of shareholders' deficit. Currency transaction gains and losses are recognized in income currently. F-10 Cash and cash equivalents Cash equivalents, including restricted cash, include U.S. Treasury securities purchased under short-term agreements to resell, bank deposits, and government and commercial notes and bills with original maturities of three months or less. Restricted cash of approximately $6 million in 1995 and 1996 is restricted under the Company's joint venture indebtedness agreement and restricted cash of approximately $4 million in 1995 and $5 million in 1996 secures undrawn letters of credit. Marketable securities and securities transactions Marketable securities are classified as either "available-for-sale" or "trading" and are carried at market based on quoted market prices. Unrealized gains and losses on trading securities are recognized in income currently. Unrealized gains and losses on available-for-sale securities, and the related deferred income tax effects, are accumulated in the marketable securities adjustment component of shareholders' deficit. See Note 4. Realized gains or losses are computed based on specific identification of the securities sold. Inventories Inventories are stated at the lower of cost (principally average cost) or market. Amounts are removed from inventories at average cost. Investment in joint ventures Investments in 20% to 50%-owned entities are accounted for by the equity method. Intangible assets Intangible assets, included in other noncurrent assets, are amortized by the straight-line method over the periods expected to be benefitted, not exceeding ten years. Property, equipment, depreciation and depletion Property and equipment are stated at cost. Interest costs related to major, long-term capital projects are capitalized as a component of construction costs. Maintenance, repairs and minor renewals are expensed; major improvements are capitalized. Depreciation is computed principally by the straight-line method over the estimated useful lives of ten to forty years for buildings and three to twenty years for machinery and equipment. Depletion of mining properties is computed by the unit-of-production and straight-line methods. F-11 Long-term debt Long-term debt is stated net of unamortized original issue discount ("OID"). OID is amortized over the period during which cash interest payments are not required and deferred financing costs are amortized over the term of the applicable issue, both by the interest method. Employee benefit plans Accounting and funding policies for retirement plans and postretirement benefits other than pensions ("OPEB") are described in Note 11. The Company accounts for stock-based employee compensation in accordance with Accounting Principles Board Opinion ("APBO") No. 25, "Accounting for Stock Issued to Employees," and its various interpretations. Under APBO No. 25, no compensation cost is generally recognized for fixed stock options in which the exercise price is not less than the market price on the grant date. Compensation cost recognized by the Company in accordance with APBO No. 25 has not been significant in each of the past three years. Environmental remediation costs Environmental remediation costs are accrued when estimated future expenditures are probable and reasonably estimable. The estimated future expenditures are not discounted to present value. Recoveries of remediation costs from other parties, if any, are reported as receivables when their receipt is deemed probable. At December 31, 1995 and 1996, no receivables for recoveries have been recognized. The Company will adopt the recognition and disclosure requirements of AICPA's Statement of Position No. 96-1, "Environmental Remediation Liabilities," in the first quarter of 1997. The new rule, among other things, expands the types of costs which must be considered in determining environmental remediation accruals. As a result of adopting the new Statement of Position, the Company expects to recognize a noncash cumulative charge of approximately $30 million in the first quarter of 1997. The charge is not expected to materially change the Company's 1997 tax expense due to existing net operating losses for which no benefit is expected to be recognized. Such charge is comprised primarily of estimated future undiscounted expenditures associated with managing and monitoring existing environmental remediation sites. The expenditures consist principally of legal and professional fees, but do not include litigation defense costs with respect to situations in which the Company asserts that no liability exists. Currently, such expenditures are expensed as incurred. Net sales Sales are recognized as products are shipped. Income taxes Deferred income tax assets and liabilities are recognized for the expected future tax consequences of temporary differences between the income tax and financial reporting carrying amounts of assets and liabilities, including investments in subsidiaries and unconsolidated affiliates not included in the F-12 Company's U.S. tax group (the "NL Tax Group"). The Company periodically evaluates its deferred tax assets and adjusts any related valuation allowance. The Company's valuation allowance is equal to the amount of deferred tax assets which the Company believes do not meet the "more-likely-than-not" realization criteria. Income (loss) per share of common stock Income (loss) per share of common stock is based on the weighted average number of common shares and equivalents outstanding. Common stock equivalents, consisting of nonqualified stock options, are excluded from the computation when their effect is antidilutive. Note 3 - Business and geographic segments: The Company's operations are conducted in two business segments - TiO2 conducted by Kronos and specialty chemicals conducted by Rheox. Titanium dioxide pigments are used to impart whiteness, brightness and opacity to a wide variety of products, including paints, plastics, paper, fibers and ceramics. Specialty chemicals include rheological additives which control the flow and leveling characteristics of a variety of products, including paints, inks, lubricants, sealants, adhesives and cosmetics. General corporate assets consist principally of cash, cash equivalents and marketable securities. At December 31, 1995 and 1996, the net assets of non-U.S. subsidiaries included in consolidated net assets approximated $121 million and $124 million, respectively.

Kronos Louisiana, Inc. ("KLA"), a wholly-owned subsidiary of Kronos, owns a 50% interest in Louisiana Pigment Company, L.P. ("LPC"). LPC is a manufacturing joint venture that is also 50%-owned by Tioxide Group, Ltd., a wholly-owned subsidiary of Imperial Chemicals Industries PLC ("Tioxide"). LPC owns and operates a chloride-process TiO2 plant in Lake Charles, Louisiana. F-15 LPC has long-term debt that is collateralized by the partnership interests of the partners and substantially all of the assets of LPC. The long-term debt consists of two tranches, one attributable to each partner, and each tranche is serviced through (i) the purchase of the plant's TiO2 output in equal quantities by the partners and (ii) cash capital contributions. KLA is required to purchase one-half of the TiO2 produced by LPC. KLA's tranche of LPC's debt is reflected as outstanding indebtedness of the Company because Kronos has guaranteed the purchase obligation relative to the debt service of its tranche. See Note 10. LPC is intended to be operated on a break-even basis and, accordingly, Kronos' transfer price for its share of the TiO2 produced is equal to its share of LPC's production costs and interest expense. Kronos' share of the production costs are reported as cost of sales as the related TiO2 acquired from LPC is sold, and its share of the interest expense is reported as a component of interest expense. Summary balance sheets of LPC are shown below.

The Company's $250 million principal amount of 11.75% Senior Secured Notes due 2003 and $188 million principal amount at maturity ($100 million proceeds at issuance) of 13% Senior Secured Discount Notes due 2005 (collectively, the "Notes") are collateralized by a series of intercompany notes from Kronos International, Inc. ("KII"), a wholly-owned subsidiary of Kronos, to NL, the interest rate and payment terms of which mirror those of the respective Notes (the "Mirror Notes"). The Senior Secured Notes are also collateralized by a first priority lien on the stock of Kronos and a second priority lien on the stock of Rheox. In the event of foreclosure, the Note holders would have access F-18 to the consolidated assets, earnings and equity of the Company. The Company believes the collateralization of the Notes, as described above, is the functional economic equivalent to a full, unconditional and joint and several guarantee of the Notes by Kronos and Rheox. The Senior Secured Notes and the Senior Secured Discount Notes are redeemable, at the Company's option, after October 2000 and October 1998, respectively. The redemption prices range from 101.5% (starting October 2000) declining to 100% (after October 2001) of the principal amount for the Senior Secured Notes and range from 106% (starting October 1998) declining to 100% (after October 2001) of the accreted value of the Senior Secured Discount Notes. In the event of a Change of Control, as defined, the Company would be required to make an offer to purchase the Notes at 101% of the principal amount of the Senior Secured Notes and 101% of the accreted value of the Senior Secured Discount Notes. The Notes are issued pursuant to indentures which contain a number of covenants and restrictions which, among other things, restrict the ability of the Company and its subsidiaries to incur debt, incur liens, pay dividends or merge or consolidate with, or sell or transfer all or substantially all of their assets to, another entity. At December 31, 1996, no amounts were available for payment of dividends pursuant to the terms of the indentures. The Senior Secured Discount Notes do not require cash interest payments through October 1998. The net carrying value of the Senior Secured Discount Notes per $100 principal amount at maturity was $70.42 and $79.87 at December 31, 1995 and 1996, respectively. At December 31, 1996, the quoted market price of the Senior Secured Notes was $106.08 per $100 principal amount and the quoted market price of the Senior Secured Discount Notes was $86.34 per $100 principal amount (1995 - - $107.06 and $80.95, respectively). At December 31, 1996, the DM credit facility consists of a DM 396 million term loan and a DM 250 million revolving credit facility, of which DM 144 million is outstanding. Borrowings bear interest at DM LIBOR plus 1.625% (5.5% and 4.76% at December 31, 1995 and 1996, respectively), and are collateralized by the stock of certain KII subsidiaries. In January 1997, the Company completed an amendment to the DM credit facility in which the Company prepaid a net DM 207 million ($127 million) of the term loan and DM 43 million ($26 million) of the revolver, leaving DM 188 million and DM 100 million outstanding, respectively. In addition, the aggregate amount available for borrowing under the revolver was reduced to DM 230 million. The majority of the cash generated from a refinancing of the Rheox term loan, discussed below, was used for a portion of such prepayments. As amended, the term loan is due in 1998 and 1999 and the revolver is due in 2000, borrowings bear interest at DM LIBOR plus 2.75%, additional collateral in the form of pledges of certain Canadian and German assets was granted and NL has guaranteed the facility. At December 31, 1996, Rheox's term loan is due in quarterly installments through December 1997, and is collateralized principally by the stock of Rheox and its U.S. subsidiaries. The term loan bears interest, at Rheox's option, at the prime rate plus 1.5% or LIBOR plus 2.5% (1995 - 8.3% with LIBOR rate borrowings; 1996 - 9.8% with prime rate borrowings). In January 1997, the Company completed a refinancing of this facility which increased the term loan to $125 million and provided for a $25 million revolving facility, generating a net $135 million in cash proceeds and credit availability. As amended, the term F-19 loan is due in quarterly installments commencing in September 1997 through January 2004 and the revolver is due no later than January 2004. The margin on LIBOR-based borrowings will range from .75% to 1.75%, depending upon the level of a certain Rheox financial ratio. After giving effect for the Rheox term loan and the amendment to the DM credit facility, unused lines of credit available for borrowing under the Rheox U.S. facility and under the Company's non-U.S. credit facilities, including the DM facility, approximated $9 million and $102 million, respectively, at December 31, 1996. Borrowings under KLA's tranche of LPC's term loan bear interest at U.S. LIBOR plus 1.625% (7.315% and 7.245% at December 31, 1995 and 1996, respectively) and are repayable in quarterly installments through September 2000. See Note 6. Notes payable at December 31, 1995 and 1996 consists of DM 56 million and DM 40 million, respectively, of short-term borrowings due within one year from non-U.S. banks with interest rates ranging from 4.25% to 4.856% in 1995 and from 3.25% to 3.70% in 1996. The aggregate maturities of long-term debt at December 31, 1996 on a historical and a pro forma basis, giving effect for the January 1997 refinancing described above, are shown in the table below.

Note 11 - Employee benefit plans: Company-sponsored pension plans The Company maintains various defined benefit and defined contribution pension plans covering substantially all employees. Personnel employed by non-U.S. subsidiaries are covered by separate plans in their respective countries and U.S. employees are covered by various plans including the Retirement Programs of NL Industries, Inc. (the "NL Pension Plan"). A majority of U.S. employees are eligible to participate in a contributory savings plan. The Company partially matches employee contributions to the Plan, and, beginning April 1996, the Company contributes to each employee's account an amount equal to approximately 3% of the employee's annual eligible earnings. The Company also has an unfunded defined contribution plan covering certain F-20 executives, and contributions are based on a formula involving eligible earnings. The Company's expense related to these plans was $.8 million in 1994, and $1.2 million in 1995 and $1.3 million in 1996. Defined pension benefits are generally based upon years of service and compensation under fixed-dollar, final pay or career average formulas, and the related expenses are based upon independent actuarial valuations. The funding policy for U.S. defined benefit plans is to contribute amounts which satisfy funding requirements of the Employee Retirement Income Security Act of 1974, as amended, and the Retirement Protection Act of 1994. Non-U.S. defined benefit pension plans are funded in accordance with applicable statutory requirements. Certain actuarial assumptions used in measuring the defined benefit pension assets, liabilities and expenses are presented below.
Years ended December 31, 1994 1995 1996 ---------- ---------- ---------- (Percentages) Discount rate ..................... 8.5 7.0 to 8.5 6.5 to 8.5 Rate of increase in future compensation levels .............. 5.0 to 6.0 3.5 to 6.0 3.5 to 6.0 Long-term rate of return on plan assets ...................... 8.5 to 9.0 8.0 to 9.0 7.0 to 9.0
During 1996, the Company curtailed certain U.S. employee pension benefits and recognized a $4.6 million gain. Plan assets are comprised primarily of investments in U.S. and non-U.S. corporate equity and debt securities, short-term investments, mutual funds and group annuity contracts. Statement of Financial Accounting Standards ("SFAS") No. 87, "Employers' Accounting for Pension Costs" requires that an additional pension liability be recognized when the unfunded accumulated pension benefit obligation exceeds the unfunded accrued pension liability. Variances from actuarially-assumed rates, including the rate of return on pension plan assets, will result in additional increases or decreases in accrued pension liabilities, pension expense and funding requirements in future periods. At December 31, 1996, 79% of the projected benefit obligations in excess of plan assets relate to non-U.S. plans. The funded status of the Company's defined benefit pension plans is set forth below.

F-22 Incentive bonus programs The Company has incentive bonus programs for certain employees providing for annual payments, which may be in the form of NL common stock, based on formulas involving the profitability of Kronos and Rheox in relation to the annual operating plan of the employee's business unit and, for most of these employees, individual performance. Postretirement benefits other than pensions In addition to providing pension benefits, the Company currently provides certain health care and life insurance benefits for eligible retired employees. Certain of the Company's U.S. and Canadian employees may become eligible for such postretirement health care and life insurance benefits if they reach retirement age while working for the Company. In 1989, the Company began phasing out such benefits for currently active U.S. employees over a ten-year period. The majority of all retirees are required to contribute a portion of the cost of their benefits and certain current and future retirees are eligible for reduced health care benefits at age 65. The Company's policy is to fund medical claims as they are incurred, net of any contributions by the retirees. For measuring the OPEB liability at December 31, 1996, the expected rate of increase in health care costs is 8% in 1997, gradually declining to 5% in 2000. Other assumptions used to measure the liability and expense are presented below.
Years ended December 31, ------------------------ 1994 1995 1996 ------- ------ ----- (Percentages) Discount rate ....................................... 8.5 7.5 7.5 Long-term rate for compensation increases ........... 6.0 4.5 6.0 Long-term rate of return on plan assets ............. 9.0 9.0 9.0
Variances from actuarially-assumed rates will result in additional increases or decreases in accrued OPEB liabilities, net periodic OPEB expense and funding requirements in future periods. If the health care cost trend rate was increased by one percentage point for each year, postretirement benefit expense would have increased approximately $.2 million in 1996, and the actuarial present value of accumulated benefit obligations at December 31, 1996 would have increased by approximately $2.2 million. During 1996, the Company curtailed certain Canadian employee OPEB benefits and recognized a $1.3 million gain. F-23

F-24 Common stock options The 1989 Long Term Performance Incentive Plan of NL Industries, Inc. (the "NL Option Plan") provides for the discretionary grant of restricted common stock, stock options, stock appreciation rights ("SARs") and other incentive compensation to officers and other key employees of the Company. Although certain stock options granted pursuant to a similar plan which preceded the NL Option Plan ("the Predecessor Option Plan") remain outstanding at December 31, 1996, no additional options may be granted under the Predecessor Option Plan. Up to five million shares of NL common stock may be issued pursuant to the NL Option Plan and at December 31, 1996, an aggregate of 2.5 million shares were available for future grants. The NL Option Plan provides for the grant of options that qualify as incentive options and for options which are not so qualified. Generally, stock options and SARs (collectively, "options") are granted at a price equal to or greater than 100% of the market price at the date of grant, vest over a five year period and expire ten years from the date of grant. Restricted stock, forfeitable unless certain periods of employment are completed, is held in escrow in the name of the grantee until the restriction period expires. No SARs have been granted under the NL Option Plan. In addition to the NL Option Plan, the Company maintains a stock option plan for its nonemployee directors. At December 31, 1996, there were options to acquire 10,000 shares of common stock outstanding of which 8,000 were fully vested. Changes in outstanding options granted pursuant to the NL Option Plan, the Predecessor Option Plan and the nonemployee director plan are summarized in the table below. F-25

At December 31, 1994, 1995 and 1996, options to purchase 850,582, 1,189,907 and 1,660,068 shares, respectively, were exercisable and options to purchase 298,698 shares become exercisable in 1997. Of the exercisable options at December 31, 1996, options to purchase 1,161,398 shares had exercise prices less than the Company's December 31, 1996 quoted market price of $10.875 per share. Outstanding options at December 31, 1996 expire at various dates through 2006, with a weighted-average remaining life of six years. The pro forma information required by SFAS No. 123, "Accounting for Stock-Based Compensation," is based on an estimation of the fair value of options issued during 1995 and 1996. The weighted average fair values of options granted during 1995 and 1996 were $6.02 and $8.38 per share, respectively. The fair values of employee stock options were calculated using the Black-Scholes stock option valuation model with the following weighted average assumptions for grants in 1995 and 1996: stock price volatility of 31% and 42% in 1995 and 1996, respectively; risk-free rate of return of 5%; no dividend yield; and an expected term of 9 years. If the fair value-based method of accounting in SFAS No. 123 had been applied, the Company's earnings per share would not have changed in 1995 and would have been reduced by $.01 per share in 1996. The pro forma impact on earnings per share for 1996 is not necessarily indicative of future effects on earnings per share. Preferred stock The Company is authorized to issue a total of five million shares of preferred stock. The rights of preferred stock as to dividends, redemption, liquidation and conversion are determined upon issuance.

The Company's valuation allowance increased in the aggregate by $31 million in each of 1994 and 1995 and $12 million in 1996. During 1995, both the Company's gross deferred tax assets and the offsetting valuation allowance were increased by $34 million as a result of recharacterizations of certain tax attributes primarily due to changes in certain tax return elections. In addition, the valuation allowance increased during 1995 by $6 million due to foreign currency translation and was reduced by approximately $10 million due to a change in estimate of the future tax benefit of certain tax credits which the Company believes satisfies the "more-likely-than-not" recognition criteria. In 1996, both the Company's gross deferred tax assets and the offsetting valuation allowance were increased by $14 million due to certain non-U.S. tax losses of its dual resident subsidiary. In addition, the valuation allowance decreased during F-28 1996 by $6 million due to foreign currency translation and was increased by $3 million as a result of increases in certain other deductible temporary differences during the year which the Company believes do not currently satisfy the "more-likely-than-not" recognition criteria. Certain of the Company's income tax returns in various U.S. and non-U.S. jurisdictions are being examined and tax authorities have proposed or may propose tax deficiencies. During 1994, the German tax authorities withdrew certain proposed tax deficiencies of DM 100 million and remitted tax refunds aggregating DM 225 million ($136 million), including interest, on a tentative basis while examination of the Company's German income tax returns continued. The Company subsequently reached an agreement with the German tax authorities regarding such examinations which resolved certain significant tax contingencies for years through 1990. The Company received final assessments and paid certain tax deficiencies of approximately DM 50 million ($32 million when paid), including interest, in settlement of these issues in 1996. The Company considers the agreement to be a favorable resolution of the contingencies and the payment was within previously-accrued amounts for such matters. Certain other German tax contingencies remain outstanding and will continue to be litigated. Although the Company believes that it will ultimately prevail in the litigation, the Company has granted a DM 100 million ($64 million at December 31, 1996) lien on its Nordenham, Germany TiO2 plant in favor of the German tax authorities until the litigation is resolved. No assurances can be given that this litigation will be resolved in the Company's favor in view of the inherent uncertainties involved in court rulings. The Company believes that it has adequately provided accruals for additional income taxes and related interest expense which may ultimately result from all such examinations and believes that the ultimate disposition of such examinations should not have a material adverse effect on the Company's consolidated financial position, results of operations or liquidity. During 1995, the Company recorded tax benefits of $6.6 million due to the reduction in dividend withholding tax rates pursuant to ratification of the U.S./Canada income tax treaty. During 1995, the Company utilized $14 million of foreign tax credit carryforwards and U.S. net operating loss carryforwards from prior years to reduce its 1995 U.S. federal income tax expense. At December 31, 1996, for U.S. federal income tax purposes, the Company had approximately $27 million of foreign tax credit carryforwards expiring during 1997 through 2001 and approximately $10 million of alternative minimum tax credit carryforwards with no expiration date. The Company also had approximately $400 million of income tax loss carryforwards in Germany with no expiration date. F-29 Note 14 - Other income, net:

Litigation settlement gains includes $20 million related to the Company's 1994 settlement of its lawsuit against Lockheed Corporation. Technology fee income was amortized by the straight-line method over a three-year period ending October 1996. Note 15 - Other items: Advertising costs, expensed as incurred, were $2 million in each of 1994, 1995 and 1996. Research, development and certain sales technical support costs, expensed as incurred, approximated $10 million in 1994, and $11 million in each of 1995 and 1996. Interest capitalized in connection with long-term capital projects was $1 million in each of 1994 and 1995, and $2 million in 1996. Note 16 - Related party transactions: The Company may be deemed to be controlled by Harold C. Simmons. Corporations that may be deemed to be controlled by or affiliated with Mr. Simmons sometimes engage in (a) intercorporate transactions such as guarantees, management and expense sharing arrangements, shared fee arrangements, joint ventures, partnerships, loans, options, advances of funds on open account, and sales, leases and exchanges of assets, including securities issued by both related and unrelated parties and (b) common investment and acquisition strategies, business combinations, reorganizations, recapitalizations, securities repurchases, and purchases and sales (and other acquisitions and dispositions) of subsidiaries, divisions or other business units, which transactions have involved both related and unrelated parties and have included transactions which resulted in the acquisition by one related party of a publicly-held minority equity interest in another related party. While no transactions of the type described above are planned or proposed with respect to the Company other than as set forth in this Annual Report on Form 10-K, the Company from time to time F-30 considers, reviews and evaluates and understands that Contran, Valhi and related entities consider, review and evaluate, such transactions. Depending upon the business, tax and other objectives then relevant, and restrictions under the indentures and other agreements, it is possible that the Company might be a party to one or more such transactions in the future. It is the policy of the Company to engage in transactions with related parties on terms, in the opinion of the Company, no less favorable to the Company than could be obtained from unrelated parties. The Company is a party to an intercorporate services agreement with Contran (the "Contran ISA") whereby Contran provides certain management services to the Company on a fee basis. Management services fee expense related to the Contran ISA was $.4 million in each of 1994, 1995 and 1996. The Company is a party to an intercorporate services agreement with Valhi (the "Valhi ISA") whereby Valhi and the Company provide certain management, financial and administrative services to each other on a fee basis. Net management services fee expense related to the Valhi ISA was $.2 million in 1994, and $.1 million in each of 1995 and 1996. The Company is party to an intercorporate services agreement with Tremont (the "Tremont ISA"). Under the terms of the contract, the Company provides certain management and financial services to Tremont on a fee basis. Management services fee income related to the Tremont ISA was nil in 1994, and $.1 million in each of 1995 and 1996. Baroid Corporation, a former wholly-owned subsidiary of the Company and currently a subsidiary of Dresser Industries, Inc., and the Company were parties to an intercorporate services agreement (the "Baroid ISA") pursuant to which, as amended, Baroid agreed to make certain services available to the Company on a fee basis. The agreement was terminated in 1994. Management services fee expense pursuant to the Baroid ISA approximated $.2 million in 1994. Sales to Baroid in the ordinary course of business were $1.8 million in 1994, $1.6 million in 1995 and $1.1 million in 1996. Purchases in the ordinary course of business from unconsolidated joint ventures, including LPC, were approximately $74 million in 1994, $79 million in 1995 and $81 million in 1996. Certain employees of the Company have been granted options to purchase Valhi common stock under the terms of Valhi's stock option plans. The Company and Valhi have agreed that the Company will pay Valhi the aggregate difference between the option price and the market value of Valhi's common stock on the exercise date of such options. For financial reporting purposes, the Company accounts for the related expense (income) ($64,000 in 1994, $(25,000) in 1995 and $1,000 in 1996) in a manner similar to accounting for SARs. At December 31, 1996, employees of the Company held options to purchase 365,000 shares of Valhi common stock at exercise prices ranging from $4.76 to $14.66 per share. At December 31, 1996, 30,000 of the vested options were exercisable at prices less than Valhi's quoted market price per share of $6.375. F-31 The Company and NLI Insurance, Ltd., a wholly-owned subsidiary of Tremont, are parties to an Insurance Sharing Agreement with respect to certain loss payments and reserves established by NLI Insurance, Ltd. that (i) arise out of claims against other entities for which the Company is responsible and (ii) are subject to payment by NLI Insurance, Ltd. under certain reinsurance contracts. Also, NLI Insurance, Ltd. will credit the Company with respect to certain underwriting profits or credit recoveries that NLI Insurance, Ltd. receives from independent reinsurers that relate to retained liabilities. Net amounts payable to affiliates are summarized in the following table.

Amounts payable to LPC are generally for the purchase of TiO2 (see Note 6), and amounts payable to Tremont principally relate to the Company's Insurance Sharing Agreement described above. Note 17 - Commitments and contingencies: Leases The Company leases, pursuant to operating leases, various manufacturing and office space and transportation equipment. Most of the leases contain purchase and/or various term renewal options at fair market and fair rental values, respectively. In most cases management expects that, in the normal course of business, leases will be renewed or replaced by other leases. Kronos' principal German operating subsidiary leases the land under its Leverkusen TiO2 production facility pursuant to a lease expiring in 2050. The Leverkusen facility, with approximately one-third of Kronos' current TiO2 production capacity, is located within the lessor's extensive manufacturing complex, and Kronos is the only unrelated party so situated. Under a separate supplies and services agreement expiring in 2011, the lessor provides some raw materials, auxiliary and operating materials and utilities services necessary to operate the Leverkusen facility. Both the lease and the supplies and services agreements restrict the Company's ability to transfer ownership or use of the Leverkusen facility. F-32 Net rent expense aggregated $8 million in 1994, $9 million in 1995 and $12 million in 1996. At December 31, 1996, minimum rental commitments under the terms of noncancellable operating leases were as follows:

Capital expenditures At December 31, 1996, the estimated cost to complete capital projects in process approximated $16 million, including a $8 million debottlenecking expansion project at the Company's Leverkusen, Germany chloride-process TiO2 facility and $2 million related to environmental protection and compliance programs. Purchase commitments The Company has long-term supply contracts that provide for the Company's chloride feedstock requirements through 2000. The agreements require the Company purchase certain minimum quantities of feedstock with average minimum annual purchase commitments aggregating approximately $115 million. Legal proceedings Lead pigment litigation. Since 1987, the Company, other past manufacturers of lead pigments for use in paint and lead-based paint and the Lead Industries Association have been named as defendants in various legal proceedings seeking damages for personal injury and property damage allegedly caused by the use of lead-based paints. Certain of these actions have been filed by or on behalf of large United States cities or their public housing authorities and certain others have been asserted as class actions. These legal proceedings seek recovery under a variety of theories, including negligent product design, failure to warn, breach of warranty, conspiracy/concert of action, enterprise liability, market share liability, intentional tort, and fraud and misrepresentation. The plaintiffs in these actions generally seek to impose on the defendants responsibility for lead paint abatement and asserted health concerns associated with the use of lead-based paints, including damages for personal injury, contribution and/or indemnification for medical expenses, medical monitoring expenses and costs for educational programs. Most of these legal proceedings are in various pre-trial stages; several are on appeal. The Company believes that these actions are without merit, intends to continue to deny all allegations of wrongdoing and liability and to defend all F-33 actions vigorously. The Company has not accrued any amounts for the pending lead pigment litigation. Considering the Company's previous involvement in the lead and lead pigment businesses, there can be no assurance that additional litigation similar to that currently pending will not be filed. Environmental matters and litigation. Some of the Company's current and former facilities, including several divested secondary lead smelters and former mining locations, are the subject of civil litigation, administrative proceedings or investigations arising under federal and state environmental laws. Additionally, in connection with past disposal practices, the Company has been named a potential responsible party ("PRP") pursuant to the Comprehensive Environmental Response, Compensation and Liability Act, as amended by the Superfund Amendments and Reauthorization Act ("CERCLA") in approximately 75 governmental and private actions associated with hazardous waste sites and former mining locations, certain of which are on the U.S. Environmental Protection Agency's Superfund National Priorities List. These actions seek cleanup costs and/or damages for personal injury or property damage. While the Company may be jointly and severally liable for such costs, in most cases it is only one of a number of PRPs who are also jointly and severally liable. In addition, the Company is a party to a number of lawsuits filed in various jurisdictions alleging CERCLA or other environmental claims. At December 31, 1996, the Company had accrued $113 million for those environmental matters which are reasonably estimable. It is not possible to estimate the range of costs for certain sites. The upper end of the range of reasonably possible costs to the Company for sites which it is possible to estimate costs is approximately $160 million. The Company's estimates of such liabilities have not been discounted to present value, and the Company has not recognized any potential insurance recoveries. The imposition of more stringent standards or requirements under environmental laws or regulations, new developments or changes respecting site cleanup costs or allocation of such costs among PRPs, or a determination that the Company is potentially responsible for the release of hazardous substances at other sites could result in expenditures in excess of amounts currently estimated by the Company to be required for such matters. No assurance can be given that actual costs will not exceed accrued amounts or the upper end of the range for sites for which estimates have been made and no assurance can be given that costs will not be incurred with respect to sites as to which no estimate presently can be made. Further, there can be no assurance that additional environmental matters will not arise in the future. As discussed in Note 2, the Company will adopt the AICPA's Statement of Position 96-1, "Environmental Remediation Liabilities," during the first quarter of 1997, increasing its environmental liability by approximately $30 million. Certain of the Company's businesses are and have been engaged in the handling, manufacture or use of substances or compounds that may be considered toxic or hazardous within the meaning of applicable environmental laws. As with other companies engaged in similar businesses, certain operations and products of the Company have the potential to cause environmental or other damage. The Company continues to implement various policies and programs in an effort to minimize these risks. The Company's policy is to comply with environmental laws and regulations at all of its facilities and to continually strive to improve environmental performance in association with applicable industry initiatives. It is possible that future developments, such as stricter requirements of F-34 environmental laws and enforcement policies thereunder, could affect the Company's production, handling, use, storage, transportation, sale or disposal of such substances as well as the Company's consolidated financial position, results of operations or liquidity. Other litigation. The Company is also involved in various other environmental, contractual, product liability and other claims and disputes incidental to its present and former businesses. The Company currently believes the disposition of all claims and disputes individually or in the aggregate, should not have a material adverse effect on the Company's consolidated financial condition, results of operations or liquidity. Concentrations of credit risk Sales of TiO2 accounted for almost 90% of net sales during the past three years. TiO2 is sold to the paint, plastics and paper industries. Such markets are generally considered "quality-of-life" markets whose demand for TiO2 is influenced by the relative economic well-being of the various geographic regions. TiO2 is sold to over 4,000 customers, none of which represents a significant portion of net sales. In each of the past three years, approximately one-half of the Company's TiO2 sales by volume were to Europe and approximately 36% in both 1994 and 1995 and 37% in 1996 of sales were attributable to North America. Consolidated cash, cash equivalents and restricted cash includes $103 million and $53 million invested in U.S. Treasury securities purchased under short-term agreements to resell at December 31, 1995 and 1996, respectively, of which $88 million and $41 million, respectively, of such securities are held in trust for the Company by a single U.S. bank.

The Borrower has a registered office in Leverkusen, Germany, and is an indirect wholly-owned subsidiary of NL Industries, Inc., a New Jersey corporation ("NL INDUSTRIES"). As of May 30, 1990, and prior to January 1, 1992, the Borrower was a wholly-owned subsidiary of Kronos (US), Inc., a Delaware corporation formerly and then known as Kronos, Inc. ("KRONOS (US)"). Effective as of January 1, 1992, Kronos (US) assigned the Stock of the Borrower to Kronos, Inc., a Delaware corporation formerly (prior to such assignment) known as Kronos (USA), Inc. ("KRONOS") and a subsidiary of Kronos (US), whereupon the Borrower became (and is now) a wholly-owned subsidiary of Kronos. The Borrower, the Banks (or their predecessors in interest), the Agent and Banque Paribas, Co-Agent for the Banks (the "CO-AGENT") were parties to that certain Loan Agreement dated as of May 30, 1990, as amended by that certain (a) First Amendment Agreement (herein so called) dated as of December 31, 1990, (b) Second Amendment Agreement (herein so called) dated as of March 22, 1991, and (c) Third Amendment Agreement (herein so called) dated as of June 15, 1992 (as amended thereby, the "ORIGINAL AGREEMENT"). Pursuant to the Original Agreement, the Borrower requested that the Banks (and/or their predecessors in interest) make, and the Banks (and/or their predecessors in interest) made, advances to the Borrower in Deutsche Mark in the aggregate principal amount of DM 1,600,000,000 on the terms and subject to the conditions and for the purposes set forth in the Original Agreement. Pursuant to the First Amendment Agreement, certain financial covenants in the Original Agreement were amended for the year 1990. Pursuant to the Second Amendment Agreement, INTER ALIA, certain financial covenants in the Original Agreement were amended, the repayment schedule for the Loan was amended and the NL/Kronos Guaranty and the Investment Account Agreement (as defined in the Original Agreement) were executed. Pursuant to the Third Amendment Agreement, INTER ALIA, certain financial covenants in the Original Agreement were amended, the repayment schedule for the Loan was amended, certain U.S. Dollar denominated tranches of the Loan were permitted, the Borrower was given the right to reborrow certain prepayments of the final repayment installment of the Loan and a Liquidity Undertaking was executed by NL Industries and Kronos (US). Effective as of January 1, 1992, the Borrower became a wholly-owned subsidiary of Kronos as explained in the second paragraph of the preamble of this Agreement. 1 During February 1993, the Borrower notified the Agent and the Co-Agent of certain proposed transactions involving its Subsidiaries, certain of which transactions were required to be approved by the requisite Banks. As a result, the First Approval Agreement was executed and the transactions described in the First Approval Agreement have been consummated (except for the transactions referred to in Step 10 of Schedule 1 to the First Approval Agreement, which transactions have not been, and need not be, consummated). The Borrower, the Banks, the Agent and the Co-Agent are parties to that certain Amended and Restated Loan Agreement dated as of October 15, 1993 (the "FIRST RESTATED AGREEMENT"), which amends and restates the Original Agreement. Pursuant to or in connection with the First Restated Agreement, (a) the Agent and the Banks (or their predecessors in interest) were requested by NL Industries, Kronos (US) and Kronos to approve, and did approve, certain transactions pursuant to which NL Industries assigned, contributed or otherwise transferred the Stock of Kronos (US) to Kronos and Kronos (US) assigned or otherwise transferred the Stock of Kronos to NL Industries, (b) a substantial prepayment of the Loan was made from proceeds of a public debt offering made by NL Industries and the maturity of the principal amount of the Loan that remained outstanding after giving effect to such prepayment was extended, and (c) the Original Agreement was amended in certain other respects. During 1994, the Borrower notified the Agent of (a) the Borrower's receipt of the Tentative Tax Refund (as hereinafter defined) relating to German income taxes for the calendar year 1990 and (b) the Borrower's position that the Tentative Tax Refund did not constitute the Tax Refund for purposes of the First Restated Agreement. In addition, in consideration of the Agent, the Co-Agent and the Banks not challenging that position and in accordance with the terms and provisions of the Tentative Tax Refund Letter (as hereinafter defined), the Borrower agreed to apply the amount of the Tentative Tax Refund as an optional prepayment of the Revolving Portion and, notwithstanding Section 2.04 of the First Restated Agreement, further agreed to not borrow all or any portion of the Tentative Tax Refund Availability Amount (as hereinafter defined) except for the purpose of (i) prior to the Final Determination Date (as defined in the Tentative Tax Refund Letter), repaying amounts constituting the Tentative Tax Refund which the Borrower became obligated to repay to the German tax authorities in respect of German tax assessments or liabilities of the Borrower and certain of its Consolidated Subsidiaries for calendar years 1989 and 1990 or (ii) at the Borrower's election, treating the amount so borrowed as a portion of the Tax Refund and prepaying the Loan pursuant to SECTION 8.01(D) of the First Restated Agreement. During 1994, the Borrower paid DM 175,000,000 to the Agent for application against the Revolving Portion in accordance with the Tentative Tax Refund Letter. On October 31, 1994, the Borrower drew down DM 50,000,000 of the Revolving Portion from the Banks under the Tentative Tax Refund Availability Amount and applied such amount (which constituted part of the Tax Refund) as a prepayment of the Term Portion in accordance with SECTION 8.01(D) of the First Restated Agreement. 2 During 1996, the Borrower notified the Agent of certain proposed transactions involving its Subsidiaries, certain of which transactions were required to be approved by the requisite Banks. As a result, the Second Approval Agreement (as hereinafter defined) was executed and the transactions described in the Second Approval Agreement have been or are in the process of being consummated. On October 22, 1996, the Borrower drew down DM 49,361,653 of the Revolving Portion from the Banks under the Tentative Tax Refund Availability Amount to pay German income taxes in accordance with the Tentative Tax Refund Letter. On January 22, 1997, the Borrower repaid DM 1,649,238 of such amount drawn on October 22, 1996, which DM 1,649,238 amount was applied to the Revolving Portion and thereby increased the Tentative Tax Refund Availability Amount by DM 1,649,238. Immediately prior to the Second Restatement Date, (a) the outstanding principal amount of the Term Portion was DM 395,537,463 and (b) the outstanding principal amount of the Revolving Portion was DM 142,784,415. In addition, immediately prior to the Second Restatement Date, the undrawn portion of the Revolving Portion was DM 107,215,585, DM 77,287,585 of which constituted the Tentative Tax Refund Availability Amount, the reborrowing of which was restricted in accordance with the terms and provisions of the Tentative Tax Refund Letter. Notwithstanding that the Final Determination Date may not have occurred, the Borrower, in consideration of the agreements of the Banks set forth in this Agreement, is willing and desires to treat the amount of DM 77,287,585 as a portion of the Tax Refund as of the Second Restatement Date subject to the terms and conditions of this Agreement. Accordingly, in accordance with SECTION 8.01(D) of the First Restated Agreement and this Agreement, the Borrower shall, on the Second Restatement Date, make a DM 77,287,585 prepayment of the Term Portion, all of which shall be applied, on a pro rata basis as provided in SECTION 8.01(D), to reduce the remaining Repayment Installments of the Term Portion, with the proceeds of a drawdown of the Revolving Portion (in accordance with the Tentative Tax Refund Letter) in the amount of DM 57,287,585 and with DM 20,000,000 of the proceeds of the NL Subordinated Loan referred to in the immediately succeeding paragraph. The Borrower, the Agent and the Banks have discussed, and desire to provide for, (a) a DM 150,000,000 prepayment of the Term Portion of the Loan to be made on the Second Restatement Date from a subordinated loan in the principal amount of DM 260,000,000 to be made by NL Industries to the Borrower and (b) certain other amendments to the First Restated Agreement. DM 20,000,000 of such prepayment will be (as stated in the immediately preceding paragraph) applied, on a pro rata basis, to reduce the remaining Repayment Installments of the Term Portion as a mandatory prepayment of part of the Tax Refund in accordance with SECTION 8.01(D) of the First Restated Agreement and this Agreement and the remaining DM 130,000,000 of such prepayment will be applied as a mandatory prepayment of the Term Portion in accordance with SECTION 8.01(H) of this Agreement and will be applied to the outstanding Repayment 3 Installments of the Term Portion in the direct order of the maturities of such installments. In order to accomplish the foregoing and to address additional matters relating thereto, the Borrower, the Banks and the Agent now desire to amend and restate the First Restated Agreement as provided in this Agreement.

ARTICLE 2. THE FACILITY 2.01 (a) The Banks (or their predecessors in interest) previously granted, through their respective Lending Offices, to the Borrower, upon the terms and subject to the conditions of the Original Agreement (as and to the extent amended by this Agreement), the Loan in the maximum aggregate principal amount of DM 1,600,000,000 (Deutsche Mark One Billion Six Hundred Million), of which DM 1,100,000,000 (Deutsche Mark One Billion One Hundred Million) was outstanding as of the First Restatement Date (prior to giving effect to the First Prepayment). On the First Prepayment Date and in accordance with SECTION 2.01 of the First Restated Agreement, but immediately prior to the making of the First Prepayment, the Loan was deemed to be divided into two portions, the Term Portion in the outstanding principal amount of DM 850,000,000 (Deutsche Mark Eight Hundred Fifty Million) and the Revolving Portion in the outstanding principal amount of DM 250,000,000 (Deutsche Mark Two Hundred Fifty Million). On the First Prepayment Date and in accordance with SECTION 2.01 of the First Restated Agreement, and promptly upon the consummation of the NL Debt Offering, NL Industries or Kronos wire transferred to the Agent (to the Agent's account specified in SECTION 11.04) immediately available funds in the amount equal to the First Prepayment Amount. The Borrower agreed that it had absolutely no control over such funds used to make the First Prepayment and that its estate was not, in any way, diminished as a result of such transfer of funds or the First Prepayment. Immediately upon the Agent's receipt of the First Prepayment, the First Prepayment was applied in accordance with SECTION 2.1 of the First Restated Agreement as a prepayment of the principal of the Loan, as follows: (i) first, DM 400,000,000 (Deutsche Mark Four Hundred Million) of the First Prepayment Amount was applied to the Term Portion; (ii) second, DM 150,000,000 (Deutsche Mark One Hundred Fifty Million) of the First Prepayment Amount was applied to the Revolving Portion as a prepayment of the Loans pursuant to SECTION 8.02; and (iii) third, an amount equal to DM 2,000,000 (Deutsche Mark Two Million) of the First Prepayment Amount was applied to the Term Portion. 40 After giving effect to such application of the First Prepayment and other prepayments made in accordance with the First Restated Agreement, the outstanding principal balance of the Term Portion was, immediately prior to the Second Restatement Date, DM 395,537,463 (Deutsche Mark Three Hundred Ninety-Five Million Five Hundred Thirty-Seven Thousand Four Hundred Sixty-Three). (b) The Banks shall continue to maintain the Loan in accordance with and subject to the terms and provisions of this Agreement. On or before the Second Restatement Date, NL Industries shall wire transfer to the Agent's account with respect to payments in Deutsche Mark specified in SECTION 11.04, in immediately available funds, proceeds of the NL Subordinated Loan in the amount equal to the Second Prepayment Amount. The Borrower agrees that it shall have absolutely no control over such funds used to make the Second Prepayment and that its estate shall not be, in any way, diminished as a result of such transfer of funds or the Second Prepayment. Immediately upon the Agent's receipt of the Second Prepayment, the Second Prepayment shall be promptly and automatically applied by the Agent as a prepayment of the principal of the Term Portion of the Loan as follows: first, DM 20,000,000 (Deutsche Mark Twenty Million) of the Second Prepayment Amount shall be applied as a mandatory prepayment of a portion of the amount equal to the Tax Refund in accordance with SECTION 8.01(D) and, second, DM 130,000,000 (Deutsche Mark One Hundred Thirty Million) of the Second Prepayment Amount shall be applied as a mandatory prepayment pursuant to SECTION 8.01(H). Also concurrently herewith, the Borrower shall cause NL Industries to wire transfer to the Borrower's account number 5803610284 maintained at Bayerische Hypotheken-und Wechselbank AG, Munich, in immediately available funds, the remainder of the proceeds of the NL Subordinated Loan in the amount of DM 110,000,000 (Deutsche Mark One Hundred Ten Million), which proceeds shall be available for general corporate purposes of the Borrower without any restriction on use of proceeds imposed by any Affiliate of the Borrower. The proceeds of the Kronos Subordinated Loan in the amount of DM 25,000,000 (Deutsche Mark Twenty-Five Million) also shall be available for working capital purposes of the Borrower without any restriction on use of proceeds imposed by any Affiliate of the Borrower. 2.02 Upon the terms and subject to the conditions of this Agreement, the Revolving Portion shall be made available to the Borrower severally by each Bank in the amount of such Bank's Revolving Commitment under this Agreement. 2.03 The failure of any Bank to perform its obligations under this Agreement shall not affect the obligations of the Borrower toward the Agent or any other Bank or the obligations of any other Bank toward the Borrower, nor shall the Agent or any other Bank be liable for the failure of such Bank to perform its obligation under this Agreement. 41 2.04 (a) The Revolving Portion may be, from time to time, prepaid in whole or in part at the option of the Borrower pursuant to SECTION 8.02 and thereafter the amounts so prepaid may be reborrowed pursuant to, and in compliance with all terms and conditions of, SECTION 2.04 and the other provisions of this Agreement. Notwithstanding anything to the contrary contained in SECTION 2.04 or elsewhere in this Agreement, the amount of the Loan that may be reborrowed by the Borrower pursuant to SECTION 2.04 at any time shall not exceed the Revolving Portion Availability at such time. The Borrower may not reborrow any amounts prepaid pursuant to SECTION 8.01 or any other provision of this Agreement (other than SECTION 8.02, to the extent permitted in the immediately preceding sentences). The Borrower and the Banks hereby acknowledge and agree that, as of the Second Restatement Date and after giving effect to the prepayment in an amount equal to the Tax Refund as referred to in SECTION 8.01(D), the Revolving Portion Availability is DM 29,928,000 (Deutsche Mark Twenty-Nine Million Nine Hundred Twenty-Eight Thousand) (i.e., the remainder of DM 230,000,000, the maximum principal amount of the Revolving Portion as of the Second Restatement Date, minus DM 200,072,000, the outstanding principal amount of the Revolving Portion as of the Second Restatement Date). (b) Upon the terms and subject to the conditions set forth in this SECTION 2.04 and elsewhere in this Agreement (including, without limitation, the Borrower's satisfaction of all conditions precedent to such reborrowing), and upon request of the Borrower made pursuant to a Notice of Borrowing delivered to the Agent in compliance with SECTION 4.02(C), each Bank agrees, severally and not jointly, to make advances of the Revolving Portion (including the Kronos Titan Revolving Portion) to or for the account of the Borrower from the First Prepayment Date to August 15, 2000, by making such amounts available to the Agent on the respective Drawdown Dates therefor pursuant to SECTION 11.06; provided, however, that (i) the principal amount of each advance of the Revolving Portion made by each Bank pursuant to this SECTION 2.04 at any time may not exceed such Bank's pro rata share (based upon its Revolving Commitment as a percentage of the aggregate Revolving Commitments of all Banks) of the Revolving Portion Availability at such time and the aggregate principal amount of all advances of the Revolving Portion made by each Bank pursuant to this SECTION 2.04 and outstanding from time to time may not exceed such Bank's pro rata share (based upon its Revolving Commitment as a percentage of the aggregate Revolving Commitments of all Banks) of the Revolving Portion and (ii) the aggregate principal amount of all advances of the Revolving Portion made by all Banks pursuant to this SECTION 2.04 at any time may not exceed the Revolving Portion Availability at such time and the aggregate principal amount of all advances of the Revolving Portion made by all Banks pursuant to this SECTION 2.04 and outstanding from time to time may not exceed the aggregate Revolving Commitments of all Banks. Unless the Agent 42 determines that any applicable condition precedent to any such reborrowing has not been satisfied, the Agent shall make the funds so received from the Banks available to the Borrower pursuant to SECTION 11.05; provided, however, that such funds consisting of drawdowns under the Kronos Titan Revolving Portion requested by Kronos Titan (together with the Borrower) shall be made available directly to Kronos Titan in accordance with SECTION 2.04(C). Each advance of the Revolving Portion made pursuant to this SECTION 2.04 shall be made as a part of a borrowing consisting of advances made by the Banks in accordance with their respective pro rata shares thereof; provided, however, that the failure of any Bank to advance its pro rata share of any such advance shall not in itself relieve any other Bank of its obligation under this SECTION 2.04 (it being agreed, however, that no Bank shall be responsible for the failure of any other Bank to do so). Prior to August 15, 2000, the Borrower may repay and reborrow under this SECTION 2.04 and the Banks shall make advances in accordance with the terms of this Agreement. The Banks shall not be obligated to make any advances of the Revolving Portion under this SECTION 2.04 subsequent to the August 15, 2000. (c) It is acknowledged and agreed by the parties hereto that Kronos Titan may utilize certain proceeds of drawdowns under the Revolving Portion. Accordingly, as of the Second Restatement Date, an amount of the Revolving Portion not to exceed DM 20,000,000 (Deutsche Mark Twenty Million) shall be designated as the "Kronos Titan Revolving Portion". The Kronos Titan Revolving Portion is, and shall be deemed to be for all purposes of this Agreement, a part of the Revolving Portion and is available to be drawn down by the Borrower in accordance with this Agreement. The Borrower and Kronos Titan agree that, notwithstanding anything to the contrary contained in this SECTION 2.04, the Borrower shall use its best efforts to ensure that the proceeds of all drawdowns under the Revolving Portion that are to be utilized by Kronos Titan, unless the Kronos Titan Revolving Portion is then fully drawn, shall be requested by Kronos Titan (together with the Borrower) to be advanced by the Agent directly to Kronos Titan. Notwithstanding anything to the contrary contained in this Agreement or any other Loan Document, each of the Borrower and Kronos Titan hereby jointly and severally agrees to repay the principal of the Kronos Titan Revolving Portion, to pay all interest accrued on such principal that is outstanding from time to time and to pay all fees accrued with respect to the Kronos Titan Revolving Portion from time to time, all in accordance with the terms and provisions of this Agreement; provided, however, that Kronos Titan so agrees only if and to the extent that such indebtedness, liabilities and obligations relate to advances under the Kronos Titan Revolving Portion advanced directly to Kronos Titan. Furthermore, the Borrower acknowledges and agrees that advances of the Kronos Titan Revolving Portion to Kronos Titan shall directly benefit the Borrower to the same extent as if such advances had been made directly to the Borrower, and that the indebtedness, liabilities and obligations of the Borrower with respect to the Kronos Titan Revolving Portion shall be identical to 43 the Borrower's indebtedness, liabilities and obligations with respect to the portion of the Revolving Portion that is not the Kronos Titan Revolving Portion. 2.05 The Borrower may, in connection with and concurrently with any Notice of Borrowing with respect to any reborrowing of the Revolving Portion pursuant to SECTION 2.04 and in connection with and concurrently with any selection of a new Interest Period pursuant to SECTION 5.02, deliver to the Agent a written request that such reborrowing or such portion of the Loan subject to such new Interest Period, as the case may be, be denominated or redenominated (as the case may be) in U.S. Dollars (as opposed to Deutsche Mark), provided, however, that the aggregate principal amount of the Loan at any time outstanding that is denominated in U.S. Dollars may not, without the prior written consent of the Banks that hold at least 80% (eighty percent) of the aggregate unpaid principal amount of the Loans, immediately upon giving effect to any such reborrowing or any such Interest Period, exceed the Base Deutsche Mark Amount of DM 350,000,000 (Deutsche Mark Three Hundred Fifty Million). Each such written request for a U.S. Dollar denominated tranche shall specify the Base Deutsche Mark Amount of such tranche. If such a written request for a U.S. Dollar denominated tranche is not received by the Agent at least five (5) Business Days prior to the proposed Drawdown Date, with respect to a Notice of Borrowing, or no later than 10:00 a.m., Luxembourg time, on the fourth (4th) Business Day prior to the beginning of the relevant Interest Period, with respect to the selection of a new Interest Period, then the tranche shall be denominated in Deutsche Mark, provided, however, that if the corresponding tranche for the Interest Period then ending is denominated in U.S. Dollars, then the tranche for the next succeeding Interest Period shall also be denominated in U.S. Dollars unless the Borrower notifies the Agent, pursuant to SECTION 5.02, that such tranche shall be redenominated in Deutsche Mark for the next succeeding Interest Period. Any agreement or obligation of the Banks to provide any portion of the Loan in Deutsche Mark or U.S. Dollars pursuant to this Agreement shall in all cases be subject to the condition that no circumstance described in SECTION 7.01 shall have occurred (as determined in good faith by the Agent) in the London interbank Euro-currency market or otherwise after request therefor by the Borrower and before the relevant Drawdown Date or the first day of the relevant Interest Period, as the case may be. If the Agent has determined that such a change has occurred, then it shall forthwith give notice thereof to the Borrower and each Bank and the procedures set forth in ARTICLE 7 shall be applicable. 2.06 (a) If the Borrower requests (pursuant to SECTION 2.05) that any reborrowing of the Revolving Portion (pursuant to SECTION 2.04) be denominated in U.S. Dollars, the Banks shall, subject to compliance by the Borrower with SECTION 2.05 and the other terms and conditions of this Agreement, make their advances of the reborrowing in U.S. Dollars in an aggregate amount equal to the Equivalent Amount of the Base Deutsche Mark Amount of the advances to be funded in U.S. Dollars. 44 (b) In the event of any advance of the Loan being redenominated in whole or in part in U.S. Dollars for the next succeeding Interest Period and such advance having been denominated in Deutsche Mark during the Interest Period then ending, each Bank will make an amount equal to the Equivalent Amount in U.S. Dollars of the Base Deutsche Mark Amount of its advance (or the relevant portion thereof) to be denominated in U.S. Dollars during the next succeeding Interest Period available to the Agent on the first day of such next succeeding Interest Period. The Agent shall, subject to the provisions of SECTION 2.06(F), make each such amount of U.S. Dollars available to the Borrower on such date and in like currency and funds as received by the Agent from the Banks in the manner provided in SECTION 11.06, and the Borrower on the last day of the Interest Period then ending shall repay the amount of such advance (or the relevant portion thereof) outstanding in Deutsche Mark during the Interest Period then ending (with accrued interest thereon in Deutsche Mark). (c) In the event that (i) any advance of the Loan denominated in U.S. Dollars is to continue to be denominated in U.S. Dollars for the next succeeding Interest Period, and (ii) as of the last day of the Interest Period then ending, the aggregate Deutsche Mark Amount of all outstanding advances of the Loan then denominated in U.S. Dollars is more than one hundred and five percent (105%) of the aggregate Base Deutsche Mark Amount of all outstanding advances of the Loan then denominated in U.S. Dollars, then the Borrower shall repay to the Agent, on the last day of such Interest Period then ending, an amount of U.S. Dollars as will result in (after giving effect to such repayment) the aggregate Deutsche Mark Amount of all outstanding advances of the Loan then denominated in U.S. Dollars, as of the last day of the Interest Period then ending, being equal to one hundred percent (100%) of the aggregate Base Deutsche Mark Amount of all outstanding advances of the Loan then denominated in U.S. Dollars. The amount to be repaid by the Borrower pursuant to this SECTION 2.06(C) shall be in addition to any Repayment Installment or other amount due and payable by the Borrower on the last day of such Interest Period then ending. In the event that (A) any advance of the Loan denominated in U.S. Dollars is to continue to be denominated in U.S. Dollars for the next succeeding Interest Period, (B) as of the last day of the Interest Period then ending, the aggregate Deutsche Mark Amount of all outstanding advances of the Loan then denominated in U.S. Dollars is less than ninety-five percent (95%) of the aggregate Base Deutsche Mark Amount of all outstanding advances of the Loan then denominated in U.S. Dollars, and (C) no Default shall have occurred and be continuing as of the last day of the Interest Period then ending, then each Bank shall make available to the Agent, and the Agent shall make available to the Borrower, on the last day of such Interest Period then ending, such Bank's pro rata share (based upon its Commitment as a percentage of the aggregate Commitments of all Banks) of an amount of U.S. Dollars as will result in (after giving effect to the delivery of such amount to the Borrower) the aggregate Deutsche Mark 45 Amount of all outstanding advances of the Loan then denominated in U.S. Dollars, as of the last day of the Interest Period then ending, being equal to one hundred percent (100%) of the aggregate Base Deutsche Mark Amount of all outstanding advances of the Loan then denominated in U.S. Dollars. The obligation of the Banks and the Agent to make such additional amounts available to the Agent and the Borrower, respectively, shall be subject, in all respects, to the condition precedent that no circumstances described in SECTION 7.01, as determined in good faith by the Agent, shall have occurred in the London interbank Euro-currency market or otherwise on or about the last day of such Interest Period then ending. (d) In the event of any advance of the Loan being redenominated in whole or in part in Deutsche Mark for the next succeeding Interest Period and such advance having been denominated in U.S. Dollars during the Interest Period then ending, each Bank will make its advance in Deutsche Mark in an amount equal to such Bank's pro rata share of the Base Deutsche Mark Amount of the aggregate advance to commence on the first day of such next succeeding Interest Period. The Agent shall, subject to the provisions of SECTION 2.06(F), make each such amount of Deutsche Mark available to the Borrower on such date and in like currency and funds as received by the Agent in the manner provided in SECTION 11.06, and the Borrower on the last day of the Interest Period then ending shall repay the amount of such advance (or the relevant portion thereof) outstanding in U.S. Dollars during the Interest Period then ending (with accrued interest therein on U.S. Dollars). (e) In the event that, with respect to any tranche requested to be denominated in U.S. Dollars, any of the events specified in SECTION 7.01 shall occur relating to U.S. Dollar deposits, then the Agent, with the consent of Majority Banks and by the giving of notice to the Borrower, may require that (i) each advance shall be made to the Borrower in Deutsche Mark in an amount equal to such Bank's pro rata share of the Base Deutsche Mark Amount of the aggregate advance requested to be made in U.S. Dollars, (ii) each advance which shall have been denominated in Deutsche Mark during the Interest Period then ending shall continue to be denominated in Deutsche Mark and (iii) each Bank shall make available to the Agent in Deutsche Mark the Base Deutsche Mark Amount of its advance which shall have been outstanding in U.S. Dollars during the Interest Period then ending on the first day of the next succeeding Interest Period. The Agent shall, subject to the provisions of SECTION 2.06(F), make such Base Deutsche Mark Amount available to the Borrower on the same date and in like currency and funds as received by the Agent from such Bank in the manner provided in SECTION 11.06 and the Borrower on the last day of the Interest Period then ending shall repay the amount of such advance denominated in U.S. Dollars during the Interest Period then ending (with accrued interest thereon in U.S. Dollars). 46 (f) In the event the Borrower is required to repay any amounts on the last day of any Interest Period pursuant to this SECTION 2.06, the Agent shall make any amounts to be advanced by the Banks available to the Borrower on the first day of the next succeeding Interest Period only if the Agent receives, concurrently therewith in accordance with this Agreement, the relevant amounts to be repaid by the Borrower pursuant to this SECTION 2.06. The Borrower hereby agrees that it shall indemnify the Agent and each Bank, and hold the Agent and each Bank harmless from and against, any and all funding or foreign exchange costs, losses or expenses that the Agent and the Banks may suffer, sustain or incur as a consequence of a failure by the Borrower to promptly pay, when due, any amounts required to be paid by the Borrower.

(c) The Borrower shall (except to the extent waived as permitted by this Agreement) cause the conditions precedent set forth in SECTION 4.01(B) to be satisfied concurrently with the Borrower's execution of this Agreement, and the Borrower shall, concurrently with its execution of this Agreement, so certify to the Agent and the Banks. 4.02 Each Drawdown of the Revolving Portion (including, without limitation, the Kronos Titan Revolving Portion) is subject to: (a) no Default having occurred; (b) all representations and warranties made by the Borrower and/or any Affiliate in the Loan Documents being true and correct as of the Drawdown Date (other than the representations and the warranties that are expressly made only in reference to another specific date); (c) the receipt by the Agent of a notice of borrowing in the form set forth in EXHIBIT P ("Notice of Borrowing"), duly completed, not less than 5 (five) Business Days prior to the proposed Drawdown Date; (d) the conditions that (i) immediately prior to giving effect to such drawdown, the outstanding principal amount of the Loan is not less than DM 100,000 (Deutsche Mark One Hundred Thousand), (ii) the Agent, as Agent for the Banks, shall have a first priority perfected security interest in the Stock of the respective Subsidiaries pledged under the Pledge Agreements as security for the Loan (including, without limitation, the Revolving Portion and any reborrowings of the Revolving Portion to be advanced on the date of any drawdown thereof), which Stock shall be free and clear of all Liens (other than such security interest securing the Loan) except for any Permitted Liens referred to in CLAUSE (D), (E), (F) OR (I) of the definition of such term in this Agreement, and (iii) the Agent, as Agent for the Banks, shall have the additional Liens as security for the Loans (including, without limitation, the Revolving Portion and any reborrowings of the Revolving Portion to be advanced on the date of any drawdown thereof) provided in SECTION 17.05, which Liens shall have the priority specified in such SECTION 17.05; and 51 (e) the condition that no Excess Adjusted Restricted Payments have been directly or indirectly paid or made by the Borrower or any of its Subsidiaries to any Affiliate of the Borrower (other than the Borrower or Subsidiaries of the Borrower) from and after January 1, 1996 (subject to the 30 (thirty) day cure period specified in the definition of "Excess Adjusted Restricted Payments"). 4.03 Each Notice of Borrowing shall be irrevocable and the Borrower shall be bound to borrow in accordance with such notice. 4.04 Upon the Agent's receipt of each (a) Notice of Borrowing, (b) notice of selection of a new Interest Period pursuant to SECTION 5.02 or (c) request that any tranche be denominated (or redenominated) in U.S. Dollars pursuant to SECTION 2.05, the Agent shall promptly notify each Bank of the contents thereof and, if applicable, of such Bank's pro rata share of any advance of the Loan to be made. Furthermore, upon the determination of the interest rate applicable to any tranche, the Agent shall promptly notify each Bank of such interest rate. ARTICLE 5. INTEREST PERIODS 5.01 The Loan proceeds shall be made available to the Borrower in no more than 4 (four) tranches for Interest Periods of 1 (one), 3 (three), 6 (six) or 12 (twelve) months with respect to each such tranche, except as provided in SECTION 5.04 and provided that the Borrower may select Interest Periods of 1 (one) month or 3 (three) months only with respect to any tranche denominated or to be denominated in U.S. Dollars. Each tranche shall be in a minimum principal amount of DM 100,000,000 (Deutsche Mark One Hundred Million) and integral multiples of DM 10,000,000 (Deutsche Mark Ten Million) in excess thereof (or the Equivalent Amount thereof in U.S. Dollars); provided, however, that any tranche evidencing a reborrowing of the Revolving Portion pursuant to SECTION 2.04 shall be in a minimum principal amount of DM 5,000,000 (Deutsche Mark Five Million) and integral multiples of DM 1,000,000 (Deutsche Mark One Million) in excess thereof (or the Equivalent Amount thereof in U.S. Dollars) and provided, further, however, that any concurrent reborrowing under the Kronos Titan Revolving Portion and reborrowing under the Revolving Portion that does not constitute the Kronos Titan Revolving Portion shall be aggregated for purposes of the immediately preceding proviso. Each tranche shall be denominated in Deutsche Mark or, if permitted by SECTION 2.05 and upon compliance by the Borrower with SECTION 2.05, U.S. Dollars, provided, however, that each tranche shall be entirely denominated in either Deutsche Mark or U.S. Dollars. 5.02 The Borrower shall inform the Agent no later than 10:00 a.m., Luxembourg time, on the 4th (fourth) Business Day prior to the beginning of the relevant Interest Period of the tenor of the next Interest Period, including, without limitation, the duration of such Interest Period and the currency (whether Deutsche Mark or U.S. Dollars) in which the tranche to be outstanding during such Interest Period is to be denominated. Unless the Agent is notified to the contrary by such time, the relevant Interest Period shall have a duration of 52 1 (one) month and the currency in which the tranche to be outstanding during such Interest Period is to be denominated shall be the same currency in which the corresponding tranche was denominated for the Interest Period then ending. 5.03 Each Interest Period for any tranche, other than the initial Interest Period, shall commence on the expiration of the immediately preceding Interest Period for such tranche. If an Interest Period would end on a day which is not a Business Day, such Interest Period shall be extended to the next succeeding Business Day unless such day falls into the next calendar month, in which event such Interest Period shall end on the immediately preceding Business Day. If any other date on which interest is payable under this Agreement is not a Business Day, then payment shall be due on the next succeeding Business Day unless such day falls into the next calendar month, in which event payment shall be due on the immediately preceding Business Day. 5.04 The Borrower may not select an Interest Period which begins prior to a Repayment Date and ends after such Repayment Date unless the aggregate amount of the tranches which have Interest Periods ending on or prior to such Repayment Date shall at least equal the principal amount of the Loan required to be paid on such Repayment Date. Notwithstanding anything herein to the contrary, the Borrower may select an Interest Period other than one, three or six months, but not to exceed six months (subject to the ability of the Reference Banks to determine the Interbank Rate for such period), for that portion of the Loan not in excess of the amount of the Loan which is scheduled to come due pursuant to ARTICLE 9 within six months of the first day of such Interest Period and which Interest Period shall end on such scheduled Repayment Date. ARTICLE 6. INTEREST 6.01 On each Interest Payment Date, the Borrower shall pay to the Agent for the account of the Banks for the Interest Period ending thereon, accrued interest, on the applicable tranche as provided in this Agreement, provided, however, that if any Interest Period is longer than 3 (three) months, accrued interest shall be payable (a) on the date in the third succeeding calendar month numerically corresponding to the commencement date of such Interest Period, or, if there exists no date numerically corresponding to the commencement date of such Interest Period in any such third succeeding month, such accrued interest shall be payable on the last Business Day of such third succeeding calendar month after the first day of such Interest Period and (b) on the Interest Payment Date. Interest shall be paid in the currency in which the applicable tranche is denominated on the applicable Interest Payment Date. 6.02 The rate of interest applicable to each tranche of the Loan during any Interest Period relating thereto shall be the Interbank Rate plus the Margin. 53 6.03 Interest payable pursuant to this Agreement shall be calculated for the actual number of days elapsed on the basis of a 360 (three hundred sixty) day year. 6.04 The Agent shall promptly notify the Borrower and each Bank of each determination of an interest rate made by the Agent under this Agreement. 6.05 All agreements between the Borrower, the Agent and the Banks, whether now existing or hereafter arising and whether written or oral, are hereby limited so that in no contingency, whether by reason of acceleration of the maturity of the Loan or otherwise, shall the interest contracted for, charged or received by the Agent, the Banks or any of them from the Borrower exceed the maximum amount permissible under applicable law. If, from any circumstance whatsoever, interest would otherwise be payable to the Agent, the Banks or any of them in excess of the maximum lawful amount, the interest payable to the Agent, the Banks or any of them shall be reduced to the maximum amount permitted under applicable law; and if from any circumstance the Agent, the Banks or any of them shall ever receive anything of value deemed interest by applicable law in excess of the maximum lawful amount, an amount equal to any excessive interest shall be applied to the reduction of the principal of the Loan and to the payment of interest, or if such excessive interest exceeds the unpaid principal balance of the Loan, such excess shall be refunded to the Borrower. All interest paid or agreed to be paid to the Agent, the Banks or any of them shall, to the extent permitted by applicable law, be amortized, prorated, allocated and spread throughout the full period until payment in full of the principal (including the period of any renewal or extension hereof) so that the interest on the Loan for such full period shall not exceed the maximum amount permitted by applicable law. This paragraph shall control all agreements between the Borrower, the Agent, the Banks or any of them. ARTICLE 7. SUBSTITUTE BASIS 7.01 If any of the following should occur: (a) the Reference Banks determine and notify the Agent that, at or about 11:00 a.m. (London time) on the Interest Determination Date for an Interest Period, no Deutsche Mark deposits (as to the portion of the Loan proposed to be denominated in Deutsche Mark) or no U.S. Dollar deposits (as to the portion of the proposed Loan to be denominated in U.S. Dollars) in the required amount for the required Interest Period are being offered to the Reference Banks by prime banks in the London interbank Euro-currency market; (b) before the close of business in Luxembourg on the Interest Determination Date for an Interest Period, the Majority Banks determine and notify the Agent that the rate at which such deposits were being so offered does not accurately reflect the cost to them of obtaining such deposits; or 54 (c) the Reference Banks shall determine and notify the Agent that, by reason of circumstances affecting the London interbank Euro-currency market generally, such deposits are not available to banks in such market or that adequate and reasonable means do not or will not exist for ascertaining the interest rate applicable to the next succeeding Interest Period; then, notwithstanding the provisions of ARTICLES 5 and 6, the Agent shall forthwith give notice of any such event to the Borrower and each Bank. 7.02 With respect to the circumstances described in SECTIONS 7.01(A) or 7.01(B) above, the Borrower may, subject to the rights of the Agent and the Banks pursuant to SECTION 2.06(E): (a) elect to prepay the applicable portion of the Loan, without premium or penalty, at the end of the then current Interest Period; or (b) select an alternative Interest Period, to the extent available as determined by the Reference Banks 2 (two) Business Days prior to the first day of the next succeeding Interest Period, during which Interest Period the applicable interest rate for the applicable portion of the Loan shall be the Interbank Rate, if available for such alternative Interest Period, plus the applicable Margin; or (c) request that the Agent, on behalf of the Banks, enter into negotiations regarding the applicable interest rate, in which event the Interest Period for the applicable portion of the Loan shall be one month and during such Interest Period the Agent, on behalf of the Banks, and the Borrower shall negotiate in good faith to agree upon an interest rate that will adequately reflect the cost to the Banks of maintaining or funding the applicable portion of the Loan for such Interest Period, and if the Borrower and the Majority Banks (662/3%) are able to agree on such interest rate, the interest rate that shall apply to the applicable portion of the Loan for such Interest Period shall be the sum of the applicable Margin and the interest rate so agreed. If the Borrower and the Agent, on behalf of the Banks, are unable to agree upon an interest rate by the day which is 2 (two) Business Days before the end of the one-month Interest Period referred to above, the interest rate that shall apply to the Loan for such Interest Period shall be (i) the rate determined by the Agent to be the arithmetic mean (rounded upwards, if necessary, to the nearest four decimal places) per annum of the respective rates notified to the Agent by each Reference Bank as that which expresses as a percentage rate per annum the cost to such Reference Bank of obtaining such deposits from such sources as it may select having reasonable regard to the interests of the Borrower, plus (ii) the applicable Margin. 55 7.03 With respect to circumstances described in SECTION 7.01(C) above, the duration of such next succeeding Interest Period shall be one month or, if the period until the next Repayment Date is less than one month, shall end on the next Repayment Date and, during such Interest Period, the Borrower and the Agent, on behalf of the Banks and subject to the consent of the Majority Banks (662/3%), shall negotiate in good faith in order to redenominate the applicable portion of the Loan in an alternative currency which is freely convertible into Deutsche Mark (which alternative currency may include, without limitation, Deutsche Mark as to the portion of the Loan proposed to be denominated in U.S. Dollars) and in which deposits are available to the Reference Banks for determining the interest rate from time to time applicable thereto (but excluding any such currency for which any central bank or other governmental authorization in the country of issue is required to permit use of such currency by a Bank for lending hereunder, if such authori zation has not been obtained and any currency the use of which as contemplated hereunder is restricted or prohibited pursuant to any request, directive, regulation or guideline of any governmental authority (whether or not having the force of law) with which any Bank is accustomed to act), and the interest rate that shall apply to the applicable portion of the Loan for such Interest Period shall be the sum of the applicable Margin and the interest rate for the alternative currency so agreed. If the Borrower and the Agent, on behalf of the Banks and with the consent of the Majority Banks (662/3%), are unable to agree on such alternative currency or an interest rate for such alternative currency by the day which is 2 (two) Business Days before the end of the Interest Period referred to above, the Borrower shall repay the applicable portion of the Loan together with accrued interest thereon at the rate determined by the Agent to be the arithmetic mean (rounded upwards, if necessary to the nearest four decimal places) of the respective rates notified to the Agent by each Reference Bank as being that which expresses as a percentage rate per annum the cost to such Reference Bank of obtaining such deposits from such sources as it may select having reasonable regard to the interests of the Borrower, plus the applicable Margin, on the next Interest Payment Date, without premium or penalty except as otherwise provided in SECTION 12.04. 7.04 During the period when any alternative interest rate or Interest Period or redenomination of the Loan or any applicable portion thereof is in force pursuant to SECTION 7.02 or 7.03 above, the Agent, in consultation with the Banks, shall periodically review whether circumstances are such that an Interbank Rate may again be determined in accordance with ARTICLES 5 and 6. If such a determination may again be made, the Agent shall forthwith give written notice thereof to the Borrower and each Bank and the Interbank Rate, plus the applicable Margin, shall be the applicable interest rate commencing with the beginning of the next Interest Period for the Loan or the applicable portion thereof. ARTICLE 8. PREPAYMENT 8.01 From and after the Prepayment Date, the Borrower shall make mandatory prepayments of the Loan as follows: 56 (a) An amount equal to the Net Proceeds (with respect to CLAUSES (2) and (3) below, only to the extent that the aggregate Net Proceeds exceed DM 15,000,000 (Deutsche Mark Fifteen Million) during any calendar year, from: (1) the Disposition by the Borrower or any of its Subsidiaries of any Stock of any Subsidiary, other than: (i) Dispositions of Stock of any of the Subsidiaries from the Borrower to any Subsidiary, from a Subsidiary to the Borrower, or between Subsidiaries; or (ii) Dispositions which constitute Restricted Payments permitted in accordance with SECTION 16.20 or Dispositions permitted in accordance with SECTION 16.15(C); (2) the Disposition by the Borrower or any of its Subsidiaries of any assets, individually or in the aggregate, or of any Stock of any Subsidiary (other than a Major Subsidiary or a Pledged Subsidiary), other than: (i) Dispositions of assets in the ordinary course of business; (ii) Dispositions from the Borrower to any Subsidiary, from a Subsidiary to the Borrower or between Subsidiaries; (iii) Dispositions which constitute Restricted Payments permitted in accordance with SECTION 16.20 or Dispositions permitted in accordance with SECTION 16.15(C); (iv) Dispositions which constitute interest payments on Subordinated Debt permitted in accordance with SECTION 16.09(D); (v) Dispositions or other events described in CLAUSES (1) or (3) of SECTION 8.01(A); or (vi) Dispositions prior to the Second Restatement Date of the distributorship/marketing arrangements existing as of the First Restatement Date between Rheox, Inc. and/or its subsidiaries and certain Subsidiaries of the Borrower; and/or (3) the Disposition, termination, shortening or other modification of the Leverkusen Lease or any agreement providing for the Disposition, termination, shortening or other modification of the Leverkusen Lease; 57 shall be used, to the extent permitted by law, to prepay the Loan, without premium or penalty except as set forth in SECTION 12.04, on the Interest Payment Date(s) immediately following the receipt by the Borrower or any Subsidiary of such Net Proceeds, in accordance with SECTION 8.01(B). If the Net Proceeds from the aforementioned Dispositions described in CLAUSES (2) or (3) of this SECTION 8.01(A) or from other transactions described in CLAUSE (3) of this SECTION 8.01(A) exceed DM 15,000,000 (Deutsche Mark Fifteen Million) in any calendar year, or, if there are any Net Proceeds from the aforementioned Dispositions described in CLAUSE (1) of this SECTION 8.01(A), then the Borrower shall in accordance with SECTION 8.01(B) make a mandatory prepayment in cash equal to the amount of such excess in the case of CLAUSES (2) and (3) or equal to the amount of such Net Proceeds in the case of CLAUSE (1), in each case whether or not the Net Proceeds are comprised of cash or non-cash proceeds. For purposes of this SECTION 8.01(A), the value of the non-cash proceeds received shall be determined in good faith by the chief financial officer of the Borrower. (b) Amounts payable under SECTION 8.01(A) shall be deposited promptly into an interest bearing account maintained in the name of the Banks with the Agent for the benefit of the Banks and shall remain on deposit with the Agent until the next Interest Payment Date(s), at which time such amounts together with interest thereon shall be applied at the Borrower's request to interest or, on a pro-rata basis, to reduce the remaining Repayment Installments of the Term Portion or, after such installments are paid in full, to permanently reduce the Revolving Portion. (c) On the Interest Payment Date(s) immediately following delivery of the financial statements in accordance with SECTION 16.01(A), the Borrower shall prepay the Loan, without premium or penalty except as set forth in SECTION 12.04, in an amount equal to 70% (seventy percent) of the amount by which Excess Cash Flow for the immediately preceding fiscal year exceeds DM 20,000,000 (Deutsche Mark Twenty Million); provided, however, that this sentence shall apply only to Excess Cash Flow for fiscal year 1996 and fiscal years prior thereto. On the earlier to occur of (a) 5 (five) days after the date upon which EBITDA for the immediately preceding fiscal year (commencing with the fiscal year 1997) has been finally determined or (b) 90 (ninety) days after the immediately preceding fiscal year end, the Borrower shall prepay the Loan, without premium or penalty except as set forth in SECTION 12.04, in an amount equal to 70% (seventy percent) of Excess EBITDA for the immediately preceding fiscal year. In addition, on or before March 31, 1997, the Borrower shall prepay the Loan, without premium or penalty except as set forth in SECTION 12.04, in an amount equal to the amount (if any) by which EBITDA of NL Industries and its subsidiaries for fiscal year 1996 exceeds $140,000,000 (One Hundred Forty Million Dollars). All such prepayments shall be applied to the Repayment Installments of the Term Portion in the inverse order 58 of the maturities of such installments or, after such installments are paid in full, to permanently reduce the Revolving Portion. (d) An amount equal to the amount of each payment received by the Borrower with respect to the Tax Refund at any time shall be used by the Borrower to prepay the Loan, without premium or penalty except as set forth in SECTION 12.04, on the Interest Payment Date(s) immediately following the date(s) upon which such payment(s) is (are) received by the Borrower. Amounts payable under this SECTION 8.01(D) shall be deposited promptly into an interest bearing account maintained in the name of the Banks with the Agent for the benefit of the Banks and shall remain on deposit until the next Interest Payment Date(s), at which time such amounts together with interest thereon shall be applied, on a pro-rata basis, to reduce the remaining Repayment Installments of the Term Portion or, after such installments are paid in full, to permanently reduce the Revolving Portion. The Borrower represents and warrants to the Agent and the Banks that all amounts drawn under the Tentative Tax Refund Availability Amount prior to the Second Restatement Date have been used to pay German income taxes or have been paid to the Agent and applied to reduce the Revolving Portion in accordance with paragraph 2 of the Tentative Tax Refund Letter. Accordingly, the Borrower, the Agent and the Banks hereby agree that (although the Final Determination Date may not yet have occurred) DM 77,287,585 (Deutsche Mark Seventy-Seven Million Two Hundred Eighty-Seven Thousand Five Hundred Eighty-Five) shall be deemed to be the remaining amount of the Tax Refund received by the Borrower as of the Second Restatement Date and not previously applied to prepay the Term Portion and that, on the Second Restatement Date, DM 57,287,585 (Deutsche Mark Fifty-Seven Million Two Hundred Eighty-Seven Thousand Five Hundred Eighty-Five) of the Tax Refund shall be drawn under the Tentative Tax Refund Availability Amount of the Revolving Portion Availability and applied to the Term Portion in accordance with this SECTION 8.01(D) and DM 20,000,000 (Deutsche Mark Twenty Million) of the proceeds of the Second Prepayment shall be applied to the Term Portion in accordance with this SECTION 8.01(D). As of the Second Restatement Date, DM 20,000,000 (Deutsche Mark Twenty Million) of the Tentative Tax Refund Availability Amount shall be deemed to have been cancelled by virtue of the reduction in the maximum principal amount of the Revolving Portion from DM 250,000,000 (Deutsche Mark Two Hundred Fifty Million) to DM 230,000,000 (Deutsche Mark Two Hundred Thirty Million). (e) On March 15, 2000, the Borrower shall prepay, and permanently reduce, the Revolving Portion in an amount equal to the positive remainder (if any) of (i) the then outstanding principal amount of the Revolving Portion minus (ii) DM 125,000,000 (Deutsche Mark One Hundred Twenty-Five Million). 59 (f) Upon the occurrence of a "Change of Control", as such term is defined in either of the Indentures, the Borrower shall promptly so notify the Agent and each of the Banks of such occurrence and shall (whether or not the Borrower complies with its obligation to give such notice) prepay the Loans, and all accrued and unpaid interest thereon to the date of the prepayment, in full on the date upon which the holders of any of the NL Notes may receive prepayment of any of the NL Notes as a result of such Change of Control (assuming such holders elect to receive such prepayment but whether or not such holders so elect) unless the Majority Banks (662/3%) shall have expressly waived such right of prepayment on or before the date upon which such prepayment is required to be made. (g) On or before 2 (two) Business Days after the last day of each calendar month upon which the aggregate cash balances of the Borrower and its Subsidiaries (excluding any cash balances of the Borrower and its Canadian Subsidiaries which are pledged to the Agent as security for the Loans and excluding U.S. Dollar cash balances held in the ordinary course of business) exceed DM 40,000,000 (Deutsche Mark Forty Million) (or the equivalent amount in any currency), the Borrower shall prepay, without premium or penalty except as set forth in SECTION 12.04, the outstanding principal amount of the Revolving Portion by the entire amount of such excess; provided, however, that the cash balances held by the Borrower immediately prior to a Repayment Date or a date upon which payments are required to be made on the Mirror Notes which are to be applied and are actually applied to make repayments of the Loan or such required payments on the Mirror Notes, respectively, shall be excluded for purposes of determining the cash balances of the Borrower and its Subsidiaries pursuant to this SECTION 8.01(G). For purposes of this SECTION 8.01(G) and SECTION 16.40, "cash balances" shall mean the aggregate of the collected cash balance in bank accounts (net of checks issued and uncleared), other cash (exclusive of petty cash maintained in reasonable amounts in the ordinary course of business) and Temporary Cash Investments. Amounts payable under this SECTION 8.01(G) shall be deposited, within such 2 (two) Business Days, into an interest bearing account maintained in the name of the Banks with the Agent for the benefit of the Banks and shall remain on deposit with the Agent until the next Interest Payment Date(s), at which time such amounts together with interest thereon shall be applied to the Revolving Portion as provided herein. The Borrower covenants and agrees that it will not, and will not permit any of its Subsidiaries to, convert non-U.S. Dollar cash balances to U.S. Dollar cash balances except to the extent reasonably necessary in the ordinary conduct of their business. (h) On the Second Restatement Date, the Borrower shall prepay the Loan, without premium or penalty except as set forth in SECTION 12.04, in the amount of DM 130,000,000 (Deutsche Mark One Hundred Thirty Million). Such prepayment 60 shall be applied to the Repayment Installments of the Term Portion in the direct order of the maturities of such installments. 8.02 The Borrower may make optional prepayments (including the portion of the First Prepayment applied toward the Revolving Portion pursuant to SECTION 2.01(A) and optional prepayments deemed made with funds provided by NL Industries and/or Kronos resulting from capital contributions made or Subordinated Debt, other than the Kronos Subordinated Loan and the NL Subordinated Loan, extended by NL Industries and/or Kronos to the Borrower) as follows: On giving not less than 5 (five) days prior written notice to the Agent, the Borrower may prepay all or any part (but in any case not less than DM 5,000,000 (Deutsche Mark Five Million) (or the Equivalent Amount thereof in U.S. Dollars) and in integral multiples of DM 1,000,000 (Deutsche Mark One Million) (or the Equivalent Amount thereof in U.S. Dollars) in excess thereof per prepayment) of the Loan on any Interest Payment Dates, without premium or penalty, except as otherwise provided in SECTION 12.04, provided that: (a) except as expressly permitted by SECTION 2.04 with respect to the Revolving Portion, each prepayment made under this Agreement may not be reborrowed under this Agreement; (b) unless the Borrower expressly informs the Agent, in connection with the aforesaid notice of such prepayment, that such prepayment shall be applied to the Revolving Portion, any prepayment under this SECTION 8.02 shall be applied to the outstanding Repayment Installments of the Term Portion in inverse order of the maturities of such installments; and (c) notice of prepayment given by the Borrower shall be irrevocable and the Borrower shall be bound to prepay in accordance with each such notice. 8.03 To the extent that the amounts available to prepay the Loan pursuant to SECTIONS 8.01 or 8.02 shall exceed the principal of the tranche relating to the immediately following Interest Payment Date, such amounts shall be applied to prepay the principal of such tranche and the remainder, if any, shall be applied to prepay the principal of the tranche relating to the next immediately following Interest Payment Date or Dates, as the case may be, until all amounts allocated for prepayment have been applied. The requirement that prepayments be applied pro rata under SECTION 8.01(B) or 8.01(D), in inverse order of maturity under SECTION 8.01(C) and SECTION 8.02 or in direct order of maturity under SECTION 8.01(H) shall not be affected by the fact that prepayments may be made on an Interest Payment Date which is also a Repayment Date. 61 ARTICLE 9. REPAYMENT Subject to the prepayment provisions set forth in ARTICLE 8, the Term Portion shall be repaid in 6 (six) installments due and payable on each of the following Repayment Dates in the following amounts: REPAYMENT DATE REPAYMENT INSTALLMENT March 15, 1997 DM 50,000,000 September 15, 1997 DM 50,000,000 March 15, 1998 DM 75,000,000 September 15, 1998 DM 75,000,000 March 15, 1999 DM 100,000,000 minus 50% (fifty percent) of the Excess Term Prepayment (if any) September 15, 1999 DM 100,000,000 minus 50% (fifty percent) of the Excess Term Prepayment (if any) Subject to the prepayment provisions set forth in ARTICLE 8, the Revolving Portion (which shall be reduced to DM 105,000,000 (Deutsche Mark One Hundred Five Million) on March 15, 2000) shall be repaid (as provided in SECTION 8.01(E)) on March 15, 2000 to the extent necessary to cause the outstanding principal amount of the Revolving Portion, after giving effect to such repayment, to equal DM 105,000,000 (Deutsche Mark One Hundred Five Million), and shall be repaid in full on September 15, 2000. All amounts owed under this Agreement with respect to the Term Portion shall be due and payable on or before September 15, 1999, in accordance with the terms of this Agreement, and all amounts owed under this Agreement with respect to the Revolving Portion shall be due and payable on or before September 15, 2000, in accordance with the terms of this Agreement. After giving effect to the mandatory prepayments to be made on the Second Restatement Date pursuant to SECTIONS 8.01(D) and 8.10(H) (including the Second Prepayment), (a) the Repayment Installments of the Term Portion previously (immediately prior to the Second Amendment Date) due on each of March 15, 1997, September 15, 1997, and March 15, 1998 shall have been paid in full and (b) the Repayment Installments of the Term Portion previously (immediately prior to the Second Amendment Date) due on each of September 15, 1998, March 15, 1999, and September 15, 1999, shall have been paid in part.

EVIDENCE OF DEBT 10.01 Each Bank shall maintain, in accordance with its usual practice, accounts evidencing the amounts from time to time lent by and owing to it under this Agreement, including such amounts with respect to each of the Term Portion and the Revolving Portion, which accounts shall be prima facie evidence of such amounts. Such amounts shall be designated in Deutsche Mark or U.S. Dollars, as appropriate, and, if designated in U.S. Dollars, shall also be designated in the corresponding Base Deutsche Mark Amount. 10.02 The Agent shall maintain on its books an account in which shall be recorded: (a) the amount of the Loan (and the currency in which each portion of the Loan is denominated or redenominated from time to time), including the amount of each of the Term Portion and the Revolving Portion outstanding from time to time, and each Bank's share therein; (b) the amount of any principal or interest due or to become due from the Borrower to the Banks under this Agreement (and the currency in which such amount is denominated or redenominated from time to time) with respect to each of the Term Portion and the Revolving Portion and each Bank's share therein; and (c) the amount of any sum received or recovered by the Agent (and the currency in which such amount is denominated) under this Agreement and each Bank's share therein. 10.03 In any legal action or proceeding arising out of or in connection with this Agreement, the entries made in the accounts maintained pursuant to SECTIONS 10.01 and 10.02 shall be prima facie evidence of the existence and amounts of the obligations and the payments of the Borrower therein recorded. In the case of any conflict between accounting under SECTION 10.01 and 10.02, the accounts of each Bank under SECTION 10.01 shall control. ARTICLE 11. PAYMENTS 11.01 Any and all payments by the Borrower and/or Kronos Titan under this Agreement shall be made without setoff or counterclaim, and free and clear of and without deduction for any and all present or future taxes, levies, imposts, deductions, charges or withholdings, and all liabilities with respect thereto, whether under U.S. or German law or otherwise, 63 excluding, in the case of each Bank and the Agent, taxes imposed on its overall net income and franchise taxes imposed on it by the jurisdiction under the laws of which such Bank or the Agent (as the case may be) is organized or any political subdivision thereof and, in the case of each Bank, taxes imposed on its overall net income and franchise taxes imposed on it by the jurisdiction of such Bank's Lending Office or any political subdivision thereof (all such excluded taxes being hereunder referred to as "Excluded Taxes" and all such non-excluded taxes, levies, imposts, deductions, charges, withholdings and liabilities being hereinafter referred to as "Taxes"). If the Borrower and/or Kronos Titan shall be required by law (whether U.S. or German or otherwise) to deduct any Taxes from or in respect of any sum payable hereunder to any Bank or the Agent, (a) and if the deductions are the result of a change in circumstances after May 30, 1990 of the type described in CLAUSE (1) of SECTION 14.01(A), the sum payable shall be increased as may be necessary so that, after making all required deductions, such Bank or the Agent (as the case may be) receives an amount equal to the sum it would have received had no such deductions been made; (b) the Borrower and/or Kronos Titan shall make such deductions; and (c) the Borrower and/or Kronos Titan shall pay the full amount deducted to the relevant taxation authority or other authority in accordance with applicable law. Any Bank claiming any additional amounts payable pursuant to this SECTION 11.01 shall use reasonable efforts (consistent with its internal policy and legal and regulatory restrictions) to transfer its portion of the Loan to a Lending Office in another jurisdiction where no such deductions are required. The Borrower and/or Kronos Titan shall forward promptly to the Agent official receipts of the relevant taxation or other authority or other evidence acceptable to the respective recipient of the amount deducted or withheld as described above, when and as such receipts or other evidence are made available to the Borrower and/or Kronos Titan by the relevant authority. 11.02 From time to time upon the request of the Borrower, Kronos Titan or the Agent, (a) each Bank organized under the laws of a jurisdiction outside the United States shall provide the Agent and the Borrower and/or Kronos Titan with a certificate, signed by an officer of each such Bank, stating that payments to be made to such Bank hereunder are expected, in the reasonable judgment of such Bank, to be exempt from United States withholding tax, if such Bank is so exempt, and the forms (if any) prescribed by the Internal Revenue Service of the United States certifying as to such Bank's status; and (b) each Bank organized under the laws of a jurisdiction outside Germany shall provide the Agent and the Borrower and/or Kronos Titan with a certificate, signed by an 64 officer of each such Bank, stating that payments to be made to such Bank hereunder are expected, in the reasonable judgment of such Bank, to be exempt from German withholding tax, if such Bank is so exempt, and the forms (if any) prescribed by the appropriate German governmental tax authority certifying as to such Bank's status. Unless the Borrower, Kronos Titan or the Agent (as applicable) has received forms or other documents satisfactory to it indicating that payments hereunder are not subject to United States or German withholding tax, as applicable, the Borrower, Kronos Titan or the Agent (as applicable) shall, unless the Borrower, Kronos Titan or the Agent (as applicable) determines that no such withholding is required, withhold taxes from such payments at the applicable statutory rate in the case of payments to or for any Bank organized under the laws of a jurisdiction outside the United States or the Federal Republic of Germany, as the case may be. If any Bank fails to furnish to the Borrower, Kronos Titan or the Agent (as applicable) forms or other documents necessary for claiming exemption from United States or German withholding tax, then payments to such Bank shall be net of any amounts the Borrower, Kronos Titan or the Agent (as applicable) is required to withhold under applicable law, provided, however, that, notwithstanding anything in this Agreement to the contrary, any Bank that is subject to withholding as a result of a change in circumstances occurring after May 30, 1990 of the type described in SECTION 14.01 shall be entitled to payments pursuant to SECTION 11.01(A). Each Bank hereby represents and warrants to the Borrower and Kronos Titan that, on the date that it became or becomes a Bank in accordance with the terms of the Original Agreement, the First Restated Agreement or this Agreement, respectively (as may be applicable), its Lending Office was or is entitled to receive payments of principal of, and interest on, Loans made by such Bank from such Lending Office without withholding or deduction for or on account of Taxes imposed by the United States of America, Germany or any respective political subdivisions of the United States of America or Germany. 11.03 If the Borrower and/or Kronos Titan makes an increased payment to any Bank pursuant to SECTION 11.01 and such Bank determines in its reasonable discretion that it has received or been granted a credit against or relief or remission for, or payment of tax paid or payable by it in respect of or calculated with reference to the deduction or withholding giving rise to such payment, such Bank shall, to the extent that it can in its sole discretion do so without prejudice to the retention of the amount of such credit, relief, remission or repayment, pay to the Borrower and/or Kronos Titan (as applicable) such amount as such Bank shall have calculated to be attributable to such deduction or withholding. If Taxes are incorrectly or illegally paid or assessed, and if any Bank or the Agent contests the payment or assessment of such Taxes, such Bank or the Agent shall refund, to the extent of any refund made to such Bank or the Agent, any amounts paid by the Borrower and/or Kronos Titan under SECTION 11.01 in respect of such Taxes. Amounts payable pursuant 65 to this SECTION 11.03 shall be paid within 30 (thirty) days from the date of receipt of the relevant refund by such Bank or the Agent (as the case may be). 11.04 All payments to be made by the Borrower and/or Kronos Titan under this Agreement shall be made in the appropriate currency (Deutsche Mark or U.S. Dollars, as applicable) and in immediately available funds not later than 10:00 a.m. (local time at Munich) on the date upon which the relevant payment is due, (a) with respect to payments in Deutsche Mark, to the Agent's account no. 6450025141 with Bayerische Hypotheken-und Wechselbank AG, Munich, or (b) with respect to payments in U.S. Dollars, to the Agent's account no. 001 1 329 026 with The Chase Manhattan Bank N.A., New York, or (in either case) to such other bank and account as the Agent may from time to time designate by written notice to the Borrower and/or Kronos Titan (as applicable). All payments (including prepayments) of principal or interest accrued with respect to the Revolving Portion of the Loans shall be applied (i) first, to the payment of interest accrued with respect to the Revolving Portion other than the Kronos Titan Revolving Portion (until such interest is paid in full), (ii) second, to the payment of the outstanding principal amount of the Revolving Portion other than the Kronos Titan Revolving Portion (until such principal is paid in full), (iii) third, to the payment of interest accrued with respect to the Kronos Titan Revolving Portion (until such interest is paid in full), and (iv) fourth, to the payment of the outstanding principal of the Kronos Titan Revolving Portion (until such principal is paid in full). 11.05 All payments to be made by the Agent to the Borrower (or, with respect to advances under the Kronos Titan Revolving Portion, Kronos Titan) under this Agreement shall be made not later than 10:00 a.m. (local time at Munich) on the date upon which the relevant payment is due and, at the risk of the Borrower (and, with respect to advances under the Kronos Titan Revolving Portion, Kronos Titan), remitted to, in the case of the Borrower, an account in Munich or Luxembourg maintained at Hypobank International S.A. or an affiliate of Hypobank International S.A. which is pledged to secure the Loans in accordance with SECTION 16.40 or, in the case of Kronos Titan, an account of Kronos Titan. 11.06 Each Bank shall make available to the Agent in the appropriate currency (Deutsche Mark or U.S. Dollars, as the case may be) as the Agent may from time to time designate its portion of the Loan hereunder prior to 10:00 a.m. (local time at Munich) on the Drawdown Date or, with respect to any redenomination of any advance pursuant to SECTION 2.06, on the first day of the next succeeding Interest Period, as the case may be, to such account as the Agent may from time to time designate for the account of the Borrower and/or Kronos Titan (as applicable). Not less than 2 (two) Business Days prior to the effective date of any initial advance of the Loan in U.S. Dollars, each Bank shall notify the Agent of the identity and location of the Lending Office for such Bank in relation to all advances and payments to be denominated in U.S. Dollars in the event that such Lending Office is different from the Lending Office previously designated for the 66 Loan, provided, however, that (a) each Bank shall utilize the Lending Office previously designated for the Loan unless it is prohibited from doing so by applicable regulatory requirements, (b) if the use of such previously designated Lending Office is so prohibited, such Bank shall use its best efforts to use a Lending Office entitled to an exemption from United States and German withholding taxes (but no Bank shall be required to establish an office or branch or obtain any authorization to engage in banking activities in any jurisdiction in order to be entitled to any exemption from United States withholding taxes), and (c) such Bank shall give written notice to the Borrower and/or Kronos Titan (as applicable) if it is unable to utilize its Lending Office previously designated for the Loan and if its Lending Office utilized for the Loan is not entitled to an exemption from U.S. and German withholding taxes, and further provided that the Borrower shall not be in any way relieved of any obligation to gross up any payments to be made to the Agent or any Bank under this Agreement. All advances to be made by each Bank in U.S. Dollars shall be made available through the Lending Office of such Bank so designated for advances in U.S. Dollars. 11.07 Except for payments received by the Agent for its account or for the account of a specific Bank in accordance with this Agreement, the Agent shall promptly distribute in like funds and currency each payment received by it for the account of the Banks ratably in proportion to their portion of the Loan or, as the case may be, their respective Commitments. 11.08 Where an amount is to be made available under this Agreement by the Agent to a Person, the Agent shall not be bound to make such amount available to such Person until the Agent has been able to establish whether or not such amount has been made available to the Agent. If the Agent makes an amount available to the Borrower and/or Kronos Titan which has not, but should have, been made available to the Agent by a Bank, the Borrower and/or Kronos Titan (as applicable) shall (without prejudice to any rights the Borrower and/or Kronos Titan (as applicable) may have against that Bank) refund that amount to the Agent on request. If the Agent makes an amount available to a Bank which has not, but should have, been made available to the Agent by the Borrower and/or Kronos Titan, that Bank shall (without prejudice to any rights it may have against the Borrower and/or Kronos Titan, as applicable) refund that amount to the Agent on a date to be determined by the Agent after consultation with such Bank. Where, in accordance with the foregoing, an amount is to be refunded to the Agent, the Agent in addition shall be indemnified by the Person who has failed to make an amount available as required under this Agreement against any reasonable interest costs actually incurred and paid by the Agent by reason of any lapse of time between the date on which the amount was made available to any Person by the Agent and the date on which the amount was refunded to the Agent in full (including, without limitation, any interest paid by the Agent in respect of funds borrowed by the Agent in order to fund such amount during such period). 11.09 Any currency specified in accordance with this Agreement shall be the currency of account and of payment in all events. The payment obligations of the Borrower and Kronos Titan hereunder shall not be discharged by an amount paid in another currency, whether 67 pursuant to a judgment or otherwise, to the extent that the amount so paid upon conversion by the Agent or the Banks (as applicable) to the specified currency under normal and reasonable banking procedures does not yield at the place when payment is due the amount of the specified currency due hereunder. In the event that any payment by or on behalf of the Borrower and/or Kronos Titan, whether pursuant to a judgment or otherwise, upon such conversion and after the deduction of all fees, costs and expenses relating thereto does not result in payment of such amount of the specified currency at the place payment is due, the Agent and each Bank shall be entitled to receive from the Borrower and/or Kronos Titan (as applicable), and shall have a separate cause of action for, the deficiency in respect of the payments due to each, respectively. ARTICLE 12. DEFAULT INTEREST AND INDEMNITY 12.01 In the event of a failure by the Borrower to pay any sum on the date on which such sum is due and payable pursuant to this Agreement and irrespective of any notice by the Agent or any other Person to the Borrower in respect of such failure, the Borrower shall pay interest on such sum, on demand, from the date of such failure up to the date of actual payment (both after and before any judgment) at the rate, increased by the sum of the Margin plus 2% (two percent), determined by the Agent to be the arithmetic mean (rounded upwards, if necessary, to the nearest four decimal places) of the rates notified to the Agent by the Reference Banks to be those at which deposits in Deutsche Mark or U.S. Dollars as the Agent may select in its discretion (after consultation with the Banks) for such period as the Agent may select in its discretion (after consultation with the Banks) are so offered to each Reference Bank by prime banks in the London interbank Euro-currency market at or about 11:00 a.m. (London time) for value 2 (two) Business Days after the Business Day immediately succeeding that on which the Agent becomes aware of such failure and, so long as the failure continues, such rate shall be recalculated on the same basis thereafter, provided that: (a) if any Reference Bank is unable or otherwise fails to furnish a quotation for the purposes of this SECTION 12.01, the interest rate shall be determined on the basis of the quotation(s) furnished by the remaining Reference Bank(s); and (b) if for any such period, none of the Reference Banks was offered deposits in the required amount and for the required period, the rate of interest applicable thereto shall be the weighted average (having regard to the respective portions of such unpaid sum) (rounded upwards, if necessary to the nearest four decimal places) per annum of the respective rates notified to the Agent by each Reference Bank as being that which expresses as a percentage rate per annum the cost to such Reference Bank of obtaining such deposits from such sources as it may select having reasonable regard to the interests of the Borrower. Interest accruing under this SECTION 12.01 shall be due and payable at the end of each period by reference to which it is calculated. 68 12.02 Without prejudice to the foregoing and irrespective of any notice by the Agent or any other Person to the Borrower in respect of the Borrower's failure to make any payment when due or in respect of any other matter relating to this SECTION 12.02, the Borrower shall indemnify the Agent and the Banks against any and all damages, losses or expenses (including, without limitation, losses incurred in paying default interest or in liquidating or employing deposits from third parties acquired to make, fund or maintain the Loan or any part thereof, including interest and penalties on unpaid Taxes, if any, and including losses on foreign currency exchanges, if any, with respect to portions of the Loan denominated in U.S. Dollars) which any of them may properly and reasonably sustain or incur as a consequence of (a) the failure by the Borrower to borrow pursuant to any Notice of Borrowing, (b) the failure by the Borrower to pay any sum, including Taxes, if any, when due and payable under this Agreement upon the occurrence of any Event of Default, (c) the funding of the Loan or any portion thereof in U.S. Dollars as opposed to Deutsche Mark or (d) the liquidation or employment of amounts borrowed or contracted for relating to, or the termination or unwinding of any contract entered into in order to fund, an advance in U.S. Dollars requested by the Borrower that, by reason of the occurrence of any event specified in SECTION 7.01, is not funded as requested. 12.03 If for the purposes of filing a claim or proof for obtaining or enforcing any judgment in any court, it is necessary to convert a sum due under this Agreement in Deutsche Mark or U.S. Dollars (as the case may be) (the "Original Currency") into another currency (the "Other Currency"), the parties hereto agree, to the fullest extent that they may effectively do so, that the rate of exchange used shall be the rate of exchange offered by any one or more of the Reference Banks to the Agent, in respect of the relevant sums, at which, in accordance with normal banking procedures, the Agent could purchase the greatest amount of the Original Currency with the Other Currency at or about 11:00 a.m. in London on the Business Day preceding that on which final judgment is given. The obligation of the Borrower in respect of any sum due in the Original Currency from it to any Bank or the Agent under this Agreement shall, notwithstanding any judgment in any Other Currency, be discharged only to the extent that on the Business Day following receipt by such Bank or the Agent (as the case may be) of any sum adjudged to be so due in such Other Currency, such Bank or the Agent (as the case may be) may in accordance with normal banking procedures purchase the Original Currency with such Other Currency. If the amount of the Original Currency so purchased is less than the sum originally due to such Bank or the Agent (as the case may be) in the Original Currency, the Borrower agrees, as a separate obligation and notwithstanding any such judgment, to indemnify immediately such Bank or the Agent (as the case may be) against such loss, and if the amount of the Original Currency so purchased exceeds the sum originally due to any Bank or the Agent (as the case may be) in the Original Currency, such Bank or the Agent (as the case may be) agrees to remit to the Borrower such excess. The above indemnity shall constitute a separate and independent obligation of the Borrower from its other obligations under this Agreement and shall apply irrespective of any grace period granted by the Agent or the Banks. 69 12.04 Any prepayment or repayment of principal made under this Agreement, if made otherwise than on an Interest Payment Date relative to the amounts prepaid or repaid, shall be made together with accrued interest thereon and such additional amount as each Bank may certify as necessary to compensate it for any damages or losses incurred or to be incurred by it in connection with such prepayment or repayment (including loss of Margin and losses on account of funds borrowed in order to make, fund or maintain its proportion of the Loan or any part thereof prepaid or repaid). ARTICLE 13. SET-OFF AND REDISTRIBUTION OF PAYMENTS 13.01 Upon the occurrence and during the continuance of any Event of Default specified in SECTION 18.01 consisting of the failure to pay principal of the Loan or any portion thereof and subject to the prior written consent of the Agent or the Majority Banks or upon the occurrence and during the continuance of any Event of Default and the acceleration of the maturity of the Loan pursuant to the provisions of ARTICLE 18, each Bank is hereby authorized at any time and from time to time, to the fullest extent permitted by law, to set off and apply any and all deposits (general or special, time or demand, provisional or final) at any time held and other indebtedness at any time owing by such Bank (at any office or branch) to or for the credit or the account of the Borrower against all or any portion of the Loan outstanding under this Agreement and other amounts payable hereunder. Each Bank agrees promptly to notify the Borrower after any such set-off and application made by such Bank, provided that the failure to give such notice shall not affect the validity of such set-off and application. The rights of each Bank under this ARTICLE 13 are in addition to other rights and remedies (including, without limitation, other rights of set-off) which such Bank may have. Each Bank agrees that if it shall, by exercising any right of set-off or counterclaim or otherwise, receive payment of a proportion of the aggregate amount of principal and interest due with respect to any portion of the Loan held by it which is greater than the proportion received by any other Bank in respect of the aggregate amount of principal and interest due with respect to any portion of the Loan held by such other Bank, the Bank receiving such proportionately greater payment shall purchase such participation in the portion of the Loan held by the other Banks, and such other adjustments shall be made, as may be required so that all such payments of principal and interest with respect to the Loans held by the Banks shall be shared by the Banks pro rata; provided that nothing in this ARTICLE 13 shall impair the right of any Bank to exercise any right of set-off or counterclaim it may have and to apply the amount subject to such exercise to the payment of indebtedness hereunder. Subject to SECTION 13.02 hereof, the Borrower agrees, to the fullest extent such holder may effectively do so under applicable law, that any holder of a participation in a Loan, whether or not acquired pursuant to the foregoing arrangements, may exercise rights of set-off or counterclaim and other rights with respect to such participation as fully as if such holder of a participation were a direct creditor of the Borrower in the amount of such participation. Anything herein to the contrary notwithstanding, nothing in this ARTICLE 13 shall impair the right of the Borrower to receive notice and to have the opportunity to cure certain Events of Default as provided in ARTICLE 18 or otherwise prior to the declaration of an acceleration of maturity. 70 13.02 Except for payments to a Bank from the Agent which were received by the Agent for the account of such Bank in accordance with the provisions of this Agreement, if any Bank shall at any time receive payment or satisfaction of all or a part of its share of the Loan, interest thereon or any other amount payable hereunder, whether by setoff, counterclaim or otherwise, in a proportion which, in relation to any amounts received by any other Bank or Banks at the same time, represents more than its percentage participation in the Loan, then such Bank shall notify the Agent thereof and shall pay to the Agent not later than 10 (ten) days after request by the Agent for account of the other Banks such amount as determined by the Agent as will ensure that each Bank will receive a proportion of such payment equal to its percentage participation. 13.03 In the event that at any time any Bank shall be required to refund to the Borrower any amount which has been paid to or received by it by set-off, counterclaim or otherwise on account of any part of the Loan, interest thereon or any other amount payable hereunder and which has been paid to any other Bank pursuant to this ARTICLE 13, such other Bank shall repay a proportionate amount of the amounts so refunded without interest. 13.04 The Borrower and the Banks expressly agree that payments by or recoveries from the Borrower shall be distributed in accordance with the provisions of this ARTICLE 13 without the need for further consent or the completion of any other formalities whatsoever. 13.05 If a Bank is required to make any payment to any other Bank pursuant to this ARTICLE 13, then, subject to SECTION 13.02, the liability of the Borrower to the Bank making such payment under this Agreement shall be treated as not having been reduced by the amount of such payment and the liability of the Borrower to any Bank receiving such payment shall be treated as having been reduced by the amount of the payment received by such Bank. ARTICLE 14. CHANGE OF CIRCUMSTANCES; ILLEGALITY; RESERVE REQUIREMENTS 14.01 Change of Circumstances (a) If, after May 30, 1990, the adoption of any applicable law, rule or regulation, or any change therein, or any change in the interpretation or administration by any governmental authority, central bank or comparable agency charged with the interpretation or administration thereof, or compliance by any Bank (or its Lending Office) with any request or directive (whether or not having the force of law) of any such authority, central bank or comparable agency: (1) shall subject any Bank (or its Lending Office) to any tax, duty or other charge with respect to the Loan or its obligation to make such Loan, or any part thereof, or shall change the basis of taxation of payments to any Bank (or its Lending Office) of the principal of or interest on its Loan, or any 71 part thereof, or any other amounts due under this Agreement in respect of its Loan or its obligation to make the Loan, or any part thereof (except for changes in the rate of tax on the overall net income of such Bank or its Lending Office imposed by the jurisdiction in which such Bank's principal executive office or Lending Office is located); or (2) shall impose, modify or deem applicable any reserve, special deposit or similar requirement, (including, without limitation, any such requirement imposed by the Federal Reserve) against assets of, deposits with or for the accounts of, or credit extended by any Bank (or its Lending Office) or shall impose on any Bank (or its Lending Office) or on the London interbank market any other condition affecting its Loan, or any part thereof, or other indebtedness under the Agreement or its obligations to make the Loan; and the result of any of the foregoing is to increase the cost to such Bank (or its Lending Office) of making or maintaining the Loan, or any portion thereof, or to reduce the amount of any sum received or receivable by such Bank (or its Lending Office) under this Agreement with respect thereto, then, within 15 (fifteen) days after demand by such Bank (with a copy to the Agent), the Borrower shall pay promptly for the account of such Bank such additional amount or amounts as will compensate such Bank for such increased cost or reduction. Such Bank shall submit to the Borrower and the Agent a certificate showing, in reasonable detail, the calculation of the amount of such increased cost. (b) If, after May 30, 1990, the adoption of any law, rule or regulation of any general applicability regarding capital adequacy, or any change therein, or any change in the interpretation or administration thereof by a governmental authority, central bank or comparable agency charged with the interpretation or administration thereof, or compliance by a Bank (or its Lending Office) with any request or directive regarding capital adequacy (whether or not having the force of law) of any such authority, central bank or comparable agency (including, without limitation, and whether promulgated or made before or after the Second Restatement Date, any law, regulation, interpretation, guideline or request contemplated by the report dated July 1988 entitled "International Convergence of Capital Measurement and Capital Standards" issued by the Basle Committee on Banking Regulations and Supervisory Practices), shall, in the determination of a Bank, have the effect of reducing the rate of return of such Bank's capital to a level below that which such Bank could have achieved as a consequence of its obligations hereunder but for such adoption, change or compliance (taking into consideration such Bank's policies with respect to capital adequacy), by an amount deemed by such Bank to be material in its sole and absolute discretion, then, within 15 (fifteen) days after demand by such Bank (with a copy to the Agent), the Borrower shall pay to such Bank such additional amount or amounts as will compensate such Bank for such reduction. 72 (c) Each Bank will notify the Borrower and the Agent promptly of any event of which it has knowledge, occurring after the First Restatement Date, which will entitle such Bank to compensation pursuant to this SECTION 14.01 and will designate a different Lending Office if such designation will avoid the need for, or reduce the amount of, such compensation and will not, in the judgment of such Bank, be otherwise disadvantageous to such Bank. A certificate of any Bank claiming compensation under this SECTION 14.01 and setting forth the additional amount or amounts to be paid to it under this Agreement shall be conclusive in the absence of manifest error. (d) Upon the occurrence of any of the events described in SECTION 14.01(A) or (B), the Borrower may prepay without premium or penalty except as otherwise provided in SECTION 12.04 such Bank's portion of the Loan together with all interest accrued thereon and all fees and other amounts (including amounts payable under SECTION 14.01(A) or (B) above) payable to such Bank hereunder, on giving not less than 10 (ten) days prior written notice to the Agent. Such Bank's Commitment shall be canceled on the giving of such notice. 14.02 ILLEGALITY (a) Notwithstanding anything to the contrary contained in this Agreement, if any change in law, regulation or treaty or in the interpretation or application thereof after May 30, 1990, by any authority charged with the administration thereof shall make it unlawful for any Bank to make, fund or maintain its portion of the Loan (although such Bank may lawfully maintain its Commitment) or to give effect to its obligations through its Lending Office as contemplated hereby, such Bank may give written notice thereof to the Agent to be forwarded by the Agent to the Borrower and the other Banks. Before giving such notice to the Agent, such Bank, to the reasonable extent possible, shall designate a different Lending Office if such designation will avoid the need for giving such notice. (b) Until such Bank notifies the Borrower and the Agent that the circumstances of the type described above no longer exist, the obligation of such Bank to make its portion of the Loan shall be suspended and the Borrower may, at its option, terminate such Bank's Commitment, by notice to such Bank and to the Agent, to be given within 30 (thirty) days after the date of notice by the Agent to the Borrower, as provided above. (c) If such Bank shall determine that it may not lawfully continue: (1) to maintain and fund its portion of the outstanding Loan to maturity; and (2) to maintain its Commitment to maturity, and shall so specify in such notice, the Borrower shall prepay, without premium or penalty except as otherwise provided in SECTION 12.04, forthwith (or if permitted by law, on the next 73 following Interest Payment Date) such Bank's portion of the Loan, together with all interest accrued thereon and all fees and other amounts payable to such Bank under this Agreement. Such Bank's obligations under this Agreement and its Commitment shall be canceled on the giving of such notice. 14.03 RESERVE REQUIREMENTS The Borrower shall pay to the Agent for the account of each Bank, so long as such Bank shall be required under regulations of the Federal Reserve to maintain reserves with respect to liabilities or assets consisting of or including Eurocurrency Liabilities, interest in addition to the applicable interest rate plus the applicable Margin on the unpaid principal amount of the applicable portion of the Loan advanced by such Bank, from the date of such Loan until such principal amount is paid in full, an amount equal to an interest rate per annum equal at all times to the remainder obtained by subtracting (i) the rate (not including the applicable Margin) for the Interest Period for such Loan, from (ii) the rate obtained by dividing the rate described in CLAUSE (I) of this SECTION 14.03 by a percentage equal to 100% (one hundred percent) minus the Eurocurrency Rate Reserve Percentage of such Bank for such Interest Period, payable on each date on which interest is payable. A certificate of each Bank setting forth in reasonable detail the calculation of the amount of such increased costs and such amounts as shall be necessary to compensate such Bank for such costs, shall be delivered to the Borrower and the Agent. The Borrower shall pay each Bank the amount shown as due on any such certificate within 30 (thirty) days after its receipt of the same. Each Bank that became a "Bank" pursuant to the Original Agreement prior to the Primary Syndication Completion Date waives the right to claim additional amounts based upon reserve requirements in effect on the date it became a Bank; provided, however, that such waiver does not apply with respect to reserve requirements to which such Bank is entitled pursuant to Regulation D. ARTICLE 15.

THE AGENT AND THE BANKS 21.01 Each Bank hereby irrevocably appoints the Agent to act as its agent in connection with this Agreement and the Loan Documents and authorizes the Agent to exercise such rights, remedies, powers and discretion as are specifically delegated to the Agent by the terms of this Agreement and the Loan Documents together with all such rights, powers and discretion as are reasonably incidental thereto. 21.02 When acting in connection with the Loan Documents, the Agent may: (a) assume that no Default has occurred and that the parties thereto are not in breach or default of their respective obligations thereunder unless the officers of the Agent immediately responsible for matters concerning this Agreement shall have actual knowledge or shall have been notified in writing by a Bank that such Bank considers that a Default exists and is continuing and specifying the nature thereof; (b) assume that each Bank's Lending Office is that identified with its signature below and on SCHEDULE 1 until it has received from such Bank written notice designating some other office of such Bank as its Lending Office and continue to act upon such notice until the same is superseded by a further such notice; 115 (c) subject to the provisions of SECTION 20.02, engage and pay for the advice or services of any lawyers, accountants or other experts whose advice or services may to it seem necessary, expedient or desirable and fully rely upon any advice so obtained;

(e) rely upon any communication or document believed by it to be genuine; (f) refrain from exercising any right, power or discretion vested in it hereunder unless and until instructed by the Majority Banks as to the manner in which such right, power or discretion should be exercised; and (g) refrain from acting in accordance with any instructions of the Majority Banks to begin any legal action or proceeding arising out of or in connection with the Loan Documents until it shall have been indemnified by the Banks to its reasonable satisfaction against any and all costs, claims, expenses (including legal fees) and liabilities which it will or may expend or incur in complying with such instructions. 21.03 The Agent shall: (a) subject to the provisions of this Agreement, promptly inform each Bank of the contents of any written notice or document received by it from the Borrower hereunder; (b) promptly notify each Bank of the occurrence of any Default under this Agreement of which the Agent has received written notice from a Bank pursuant to SECTION 21.02; (c) subject to the provisions of this Agreement, act in accordance with any written instructions given to it by the Majority Banks; (d) if so instructed by the Majority Banks in writing, refrain from exercising any right, power or discretion vested in it hereunder; and (e) administer and service the Loan in accordance with its customary procedures and practices in the administration and servicing of loans of a similar nature made by the Agent, and the Agent shall have the authority to make decisions hereunder in connection with the day-to-day administration and servicing of the Loan, and each Bank shall be bound thereby. 21.04 Neither the Agent nor any of its directors, officers, employees, agents or Affiliates, shall: 116 (a) be bound to inquire as to the occurrence or otherwise of any Default or Event of Default or as to any failure of the Borrower or any Affiliate duly to perform its obligations hereunder or under the Loan Documents; (b) be bound to account to any Bank for any sum or the profit element of any sum received by it for its own account; (c) be bound to disclose to any other Person any information relating to the Borrower or any of the Borrower's Affiliates received by it if such disclosure would or might in the opinion of any of the above Persons constitute a breach of any law or regulation or be otherwise actionable by suit of any Person; (d) be under any fiduciary duty towards any Bank or under any obligations other than those for which express provision is made herein; (e) be liable for any action taken or omitted to be taken except for their own gross negligence or wilful misconduct; or (f) be liable for any error in computing any amount payable to any Bank, provided, that the Agent, the Borrower and any affected Bank, upon discovery of such error, shall make such adjustments as may be required to correct such error. 21.05 Each Bank agrees to indemnify the Agent and its directors, officers, employees, agents and Affiliates to the extent not reimbursed by the Borrower in the proportion of its share in the Loan (or, if no amount is outstanding, its Commitment) for any and all liabilities, obligations, losses, damages, penalties, actions, judgments, suits, costs, expenses or disbursements of any kind and nature whatsoever which may be imposed on, incurred by or asserted against the Agent and its directors, officers, employees, agents or Affiliates in any way relating to or arising out of the First Restated Agreement, this Agreement or any other Loan Documents, or any other documents contemplated by or referred to herein or the transactions contemplated hereby (including, without limitation, the costs and expenses which the Borrower is obligated to pay under ARTICLE 20 but excluding, unless an Event of Default has occurred and is continuing, normal administrative costs and expenses incident to the performance of its Agent's agency duties hereunder) or the enforcement of any of the terms of the First Restated Agreement, this Agreement, the Loan Documents or of any such other documents, provided that no Bank shall be liable for any of the foregoing to the extent they arise from the Agent's gross negligence or wilful misconduct. 21.06 Each Bank agrees that the Agent shall not be responsible for the accuracy or completeness of any representation made (whether orally or otherwise) herein or in connection herewith, for the proper form, validity, effectiveness, adequacy or enforceability of the Original Agreement, the First Restated Agreement, this Agreement, any Guaranty, the Pledge Agreements, the Nordenham Mortgage, the Canadian Security Documents, the Cash Pledge Agreements or any of the other Loan Documents or for the creditworthiness of the Borrower, any Guarantor, Pledgor, Pledged Subsidiary or any Affiliate of the foregoing 117 entities. Neither the Agent nor any of its directors, officers, employees, agents or Affiliates shall be under any liability for or in respect of any action taken or omitted by any of them in relation to the Original Agreement, the First Restated Agreement, this Agreement, any Guaranty, the Pledge Agreements, the Nordenham Mortgage, the Canadian Security Documents, the Cash Pledge Agreements or any of the other Loan Documents except for their gross negligence or wilful misconduct. 21.07 The Agent may accept deposits from, lend money to and generally engage in any kind of banking or other business with the Borrower or any Affiliate, independently of the transactions contemplated herein. 21.08 It is understood and agreed by each Bank that it has been, and will continue to be, solely responsible, without reliance upon the Agent, for making its own independent appraisal of and investigations into the financial condition, creditworthiness and affairs of the Borrower, any Guarantor, the Pledgors, Pledged Subsidiaries and Affiliates of the foregoing entities and the value of the Collateral or the validity, enforceability or genuineness of the Original Agreement, the First Restated Agreement, this Agreement or any of the Loan Documents and accordingly each Bank confirms to the Agent that it has not relied, and will not hereafter rely, on the Agent: (a) to check or inquire on its behalf into the adequacy, accuracy or completeness of any information provided by the Borrower or any Affiliates, director, officer, employee or agent thereof in connection with the Loan Documents or the transactions therein contemplated whether or not such information has been or is hereafter circulated to such Bank by the Agent; or (b) to assess or keep under review on its behalf the financial condition, creditworthiness or affairs of the Borrower or its Affiliates and the value and/or enforceability of the Collateral. 21.09 The Agent may at any time be removed by the Majority Banks upon at least 30 (thirty) days prior written notice to such Agent of such removal but only for cause consisting of gross negligence or wilful misconduct or following a declaration of insolvency by the appropriate regulators. The Agent may at any time resign from the agency upon not less than 45 (forty-five) days' notice to the Banks of its intention to do so and, if any such notice is given by the Agent, the Agent shall, upon the appointment of a successor agent as hereinafter provided for, cease to be under any further obligation as Agent hereunder. Within such period, the Majority Banks may appoint a successor agent with the consent of the Borrower, which consent will not be unreasonably withheld or delayed and if, before the expiry of such notice, such successor agent notifies the parties hereto that it accepts such appointment: (a) each reference herein to the "Agent" shall thereafter be construed as a reference to the successor agent; and 118 (b) the successor agent and the parties hereto other than the retiring Agent shall thereafter have such rights and obligations inter se as they would have if the successor agent had been named herein as the Agent. If no successor agent, appointed by the Majority Banks, notifies the parties hereto, prior to the expiry of the Agent's notice of its intention to retire from the agency giving rise to the need to appoint the same, of its acceptance of such appointment, the Agent may appoint any experienced and reputable bank having offices in London, Munich, New York City or Luxembourg to be the successor agent and, if it does and such successor agent notifies the parties hereto that it accepts such appointment: (i) each reference herein to the "Agent" shall thereafter be construed as a reference to the successor agent so appointed; and (ii) the successor agent so appointed upon execution of a counterpart of this Agreement and the parties hereto other than the retiring Agent shall thereafter have such rights and obligations inter se as they would have if the successor agent so appointed had been named herein as the Agent. Until the Borrower receives written notice of the appointment of a new Agent, the Borrower shall be entitled to continue to send notices and payments to the previously appointed Agent and otherwise to treat such Agent as the Agent for purposes of this Agreement. 21.10 If any Reference Bank shall be prepaid under this Agreement or shall cease to have any Commitment or after the Second Restatement Date cease to have any principal or interest owing to it hereunder, the Agent may in consultation with the Banks and the Borrower appoint a substitute Reference Bank. 21.11 The provisions of this ARTICLE 21 are solely for the benefit of the Agent and the Banks and neither the Borrower nor any Subsidiary or Affiliate of the Borrower shall have any rights (whether as third party beneficiary or otherwise) except as specifically provided herein. ARTICLE 22. NO WAIVER No failure to exercise and no delay in exercising on the part of the Agent or any Bank of any right, power or privilege hereunder shall operate as a waiver thereof, nor shall any single or partial exercise of any right, power or privilege preclude any other or future exercise thereof, or the exercise of any other right, power or privilege. The rights and privileges herein provided are cumulative and not exclusive of any rights or remedies provided by law in equity or otherwise. This Agreement may be amended and any provision of this Agreement may be waived only with the consent of the Majority Banks, provided, however, that no amendment or waiver shall, unless in writing and signed by each Bank affected thereby, do any of the following: (1) reduce the principal or the rate of interest payable by the Borrower on any Loan or reduce any fees payable to the Banks under this Agreement; 119 (2) postpone the date fixed for the payment of principal of or interest on the Loan or any fees to the Banks under this Agreement; (3) increase the Commitment of any Bank or subject any Bank to any additional obligation to make Loans; or (4) amend this ARTICLE 22; provided, further, that no amendment or waiver shall be effected which releases or impairs or otherwise compromises any Collateral or substitutes Collateral without the prior written consent of the Majority Banks (662/3%) other than in the case of the NL Undertaking for which the consent of the Majority Banks shall be required; and provided further that no such amendment or waiver or consent, as the case may be, which has the effect of (i) increasing the duties or obligations of the Agent under this Agreement or of the Agent under any other Loan Document, or (ii) increasing the standard of care or performance required on the part of the Agent under this Agreement or of the Agent under any other Loan Document, or (iii) reducing or eliminating the indemnities or immunities to which the Agent is entitled hereunder (including any amendment or modification of this ARTICLE 22), shall be effective unless the same shall be signed by or on behalf of the Agent. ARTICLE 23. PARTIAL INVALIDITY; CHANGE IN ACCOUNTING PRINCIPLES 23.01 If at any time any provision of this Agreement or other Loan Documents to which the Borrower or any of its Affiliates is a signatory is or becomes illegal, invalid or unenforceable in any respect under the law of any jurisdiction, the legality, validity or enforceability of the remaining provisions under this Agreement or such Loan Document shall not in any way be affected or impaired thereby. Such illegal, invalid or unenforceable provisions shall be replaced by legal, valid and enforceable provisions, the economic and legal effects of which are as close as possible to that of the invalid illegal or unenforceable provisions. 23.02 If any changes in German GAAP or other applicable accounting principles after the First Restatement Date result in a change of the interpretation, calculation or method of calculation of financial covenants, ratios, standards or terms contained in this Agreement (the "Financial Covenants") which is materially different from the interpretation, calculation or method of calculation of the Financial Covenants on the First Restatement Date, the parties hereto agree to enter into negotiations with a view to amending the Financial Covenants so that the criteria for evaluating the financial condition of the Borrower and its Subsidiaries shall be the same as if such change had not been made. ARTICLE 24. ASSIGNMENTS, PARTICIPATION 24.01 The Borrower may not assign or transfer all or any of its rights, benefits and obligations under this Agreement without the prior written consent of the Majority Banks (662/3%); provided, however, that nothing in this SECTION 24.01 shall affect the ability of the 120 Borrower to merge or consolidate in accordance with the terms of SECTION 16.10. 24.02 (a) Notwithstanding any other provision contained in this Agreement or any other documents, no Bank may assign or transfer any of its interests under this Agreement except in accordance with the provisions of this SECTION 24.02 and no Bank may transfer, assign or grant participations in its rights and/or delegations under this Agreement except in accordance with this SECTION 24.02; provided, however, that nothing in this SECTION 24.02 or in this Agreement shall prevent, subject to SECTION 24.03, any Bank assigning or granting participations in such Bank's interests under this Agreement to such Bank's parent bank holding company or to any affiliate in which such Bank or parent bank holding company has the power to vote at least 33 1/3% of the voting securities issued by such affiliate for the election of the board of directors (or members of an equivalent governing body), provided, however, that such affiliate assignee may only further assign or subparticipate its interests in Loans pursuant to the terms of this ARTICLE 24 and provided, however, that such affiliate assignee cannot further assign or subparticipate its interests in Loans to any Person which is an affiliate pursuant to the provisions of SECTION 24.02(A). (b) Each Bank shall have the right to transfer, assign or grant participations in all or any part of its remaining rights and obligations under this Agreement on the basis and subject to the conditions set forth below in this SUBSECTION 24.02(B). (i) Each Bank may assign all or a portion of its rights and obligations under this Agreement to any Person in accordance with the terms of this SECTION 24.02.

The records shall be available for inspection by the Borrower or any Bank at any reasonable time and from time to time upon reasonable prior notice. 24.06 Upon its receipt of an Assignment and Acceptance executed by an assigning Bank and an assignee, the Agent shall, if such Assignment and Acceptance has been completed and is 123 in substantially the form of EXHIBIT A hereto, as the case may be, (i) accept such Assignment and Acceptance, (ii) record the information contained therein, and (iii) give prompt notice thereof to the Borrower. 24.07 Each of the Agent and each Bank which is a signatory to this Agreement shall execute a Confidentiality Agreement in the form of EXHIBIT S attached hereto on or prior to the date of its execution of this Agreement.

                              means,  with  respect to any  Person,  the amount,
                              expressed in Deutsche Mark, equal to the remainder
                              of (A) the  sum of such  Person's  cash  and  cash
                              equivalents  (determined in accordance with German

                              without  duplication,  the aggregate amount of any

                              Lien in favor of Agent as security  for the Loans,
                              affecting  such  cash,  cash  equivalents   and/or
                              Marketable  Securities (in each case not to exceed

                              As used herein,  the term "Marketable  Securities"
                              means all stocks, bonds, notes or other securities
                              which  are  regularly  traded  on  any  recognized
                              national or  international  market or exchange and
                              are  otherwise  freely  transferable.  The  market
                              value of Marketable Securities shall be determined
                              as of each Date of Determination by reference to a
                              market   price   quoted  as  of  such  date  in  a
                              recognized  national  or  international  market or
                              exchange for the Marketable Securities in question
                              and otherwise on a basis  reasonably  satisfactory
                              to  the  Majority   Banks.   If  any  cash,   cash
                              equivalent or the value of  Marketable  Securities
                              is denominated in any currency other than Deutsche
                              Mark,  then, for purposes of calculating  the Cash
                              Position  under  this  Agreement,  the  equivalent
                              amount of  Deutsche  Mark shall be  determined  by
                              using the Spot Rate existing as of the  applicable
                              Date of Determination.  As used in this Agreement,
                              the term "Spot Rate", with respect to any currency
                              and any day,  means the rate  determined  based on
                              the "Frankfurt  Foreign  Exchange  Fixing" for the
                              offered rates to purchase  Deutsche Mark with such
                              currency as reflected on the display designated as
                              page "1011" on the Telerate Systems,  Incorporated
                              service  (or such other page as may  replace  page
                              "1011"  on  that   service  for  the  purposes  of
                              displaying  such offered  rates) at or about 11:00
                              a.m.  London  time on such  date.  If at least two
                              such  offered  rates appear on such  display,  the
                              rate for such date will be the arithmetic  mean of
                              such offered rates.

                        (ii)  Borrower Liquidity Deficit;  Required  Investment.
                              If  Borrower's  Liquidity  Level  is less  than DM
                              25,000,000  (Deutsche Mark Twenty Five Million) as
                              of any Date of Determination,  Shareholders  shall
                              on a joint, several, irrevocable and unconditional
                              basis  (but  subject to  subparagraph  (d) of this
                              Paragraph  2),  within ten (10) days  after  being
                              given the applicable  Liquidity Report (or if such

                              days after being given written  notice from Agent)
                              either  make  Capital  Contributions  to  Borrower
                              and/or make  Subordinated  Loans to  Borrower,  in
                              either case in an aggregate  amount  sufficient so
                              that,  after giving  effect to such  contributions
                              and/or such loans and the receipt of such funds by
                              Borrower,  Borrower's  Liquidity Level (calculated
                              as if such contributions and/or

                              loans  were  made  as of the  applicable  Date  of
                              Determination) shall equal or exceed DM 25,000,000
                              (Deutsche Mark Twenty Five Million); provided that
                              the aggregate amount of Capital  Contributions and
                              Subordinated   Loans  made  by   Shareholders   to
                              Borrower  after  January  31,  1997  and  prior to
                              January 1, 2001 pursuant to this  Agreement  shall
                              not  exceed  an  aggregate   amount  equal  to  DM

                              Million)   (the   "Maximum   Required   Investment
                              Amount");  and provided further that Shareholders'
                              obligations to make Capital  Contributions  and/or
                              Subordinated  Loans  up to  the  Maximum  Required
                              Investment Amount shall be satisfied by any of the
                              following:  (A) to  the  extent  and in an  amount
                              equal  to,  as of the date of  determination,  the
                              positive  remainder  (if any) of (1) the aggregate
                              amount   of    Shareholders'    optional   Capital
                              Contributions  and/or  Subordinated  Loans made to
                              Borrower   after  January  31,  1997  for  general
                              corporate purposes (including, without limitation,
                              optional  prepayments)  minus  (2)  the sum of the
                              aggregate  amount of  Restricted  Payments made by
                              Borrower  prior to the date of  determination  but
                              after   January  31,  1997   pursuant  to  Section
                              16.20(b) of the Loan  Agreement plus the aggregate
                              amount of Restricted Payments permitted (as of the
                              date of  determination)  to be made by Borrower on
                              or after  the date of  determination  pursuant  to
                              Section 16.20(b) of the Loan Agreement, and (B) an
                              amount equal to the Liquidity  Undertaking  Credit
                              in  effect  as of the date of  determination.  The
                              term "Capital  Contributions"  means contributions
                              by a  Shareholder  to the equity of Borrower.  The
                              term   "Subordinated   Loans"  means  loans  by  a
                              Shareholder  to Borrower  on terms and  provisions
                              acceptable  to  such   Shareholder  and  Borrower;
                              provided that such loans are "Subordinated  Debt",
                              as such term is defined in the Loan Agreement.

                        (iii) Event    of    Default;    Required    Investment.
                              Notwithstanding anything to the contrary contained
                              elsewhere  in  this  Agreement,  if  an  Event  of
                              Default has occurred and is  continuing  and Agent
                              shall have given Borrower and Shareholders written
                              notice  requesting or requiring  performance under
                              this   subparagraph   (c),   then   Borrower   and
                              Shareholders'   jointly  and  severally  agree  as
                              follows:


SECOND AMENDED AND RESTATED LIQUIDITY UNDERTAKING - Page 4







                  (i) a  Liquidity  Report  shall be  provided  by  Borrower  to
            Shareholders  and Agent  within two Business  Days after  Borrower's
            receipt of such notice referred to in this  subparagraph  (c), which
            Liquidity Report shall identify Borrower's Liquidity Level as of the
            Business  Day  immediately  succeeding  the date of such notice (the
            "Default  Date  of  Determination");  provided,  however  that,  for
            purposes of this  subparagraph (c), the term "Liquidity Level" shall
            mean (without  duplication)  (A) the  Liquidity  Level as defined in
            subparagraph (a) of this Paragraph 2 minus, (B) the aggregate unpaid
            principal  amount  of the  Loans,  minus  (C) the  aggregate  of the
            accrued and unpaid  interest and fees under the Loan  Agreement  and
            the other Loan Documents; and

                  (ii)  based  upon  the  Liquidity  Level as so  determined  in
            accordance with clause (i) immediately  preceding,  the Shareholders
            shall, on a joint, several, irrevocable and unconditional basis (but
            subject to  subparagraph  (d) of this  Paragraph 2), within ten (10)
            days after being given such notice from Agent,  either make  Capital
            Contributions  to  Borrower  and/or  make   Subordinated   Loans  to
            Borrower,  in either case in an aggregate amount sufficient so that,
            after giving effect to such contributions  and/or such loans and the
            receipt of such funds by Borrower,  Borrower's  Liquidity  Level (as
            defined  in  this   subparagraph  (c)  and  calculated  as  if  such
            contributions  and/or loans were made as of the  applicable  Default
            Date of Determination) shall equal or exceed DM 25,000,000 (Deutsche
            Mark Twenty Five  Million);  provided that the  aggregate  amount of
            Capital Contributions and Subordinated Loans made by Shareholders to
            Borrower  after  January  31,  1997 and  prior to  January  1,  2001
            pursuant to this  Agreement  shall not exceed the  Maximum  Required
            Investment Amount. Notwithstanding anything to the contrary that may
            be contained in this Agreement,  payments by NL Industries under the
            NL Guaranty will not reduce or otherwise affect the Maximum Required
            Investment Amount.

                        (iv)  Priority of Contributions  by  Shareholders.  Each
                              time the Shareholders are required to make Capital
                              Contributions or Subordinated Loans (the "Required
                              Contributions")  under subparagraphs (b) or (c) of
                              this  Paragraph  2, Kronos  shall be  obligated to
                              make so much of the Required  Contributions  as it
                              is  able  to  make  from  funds  received  from or
                              otherwise attributable to its operations before NL
                              Industries  (i) makes any portion of the  Required
                              Contributions or (ii) contributes  funds to Kronos
                              to   enable    Kronos   to   make   the   Required
                              Contributions.  Kronos  agrees  that it  will  not
                              utilize any funds  received  from NL Industries to
                              make  any  Required  Contributions  until  it  has
                              utilized  all the then  available  funds which are
                              received  from or  otherwise  attributable  to its
                              operations.   After  Kronos  has   satisfied   its
                              obligations under the preceding two sentences or

SECOND AMENDED AND RESTATED LIQUIDITY UNDERTAKING - Page 5







                              if   Kronos    is   unable   to   make    Required
                              Contributions,   then  NL   Industries   will,  if
                              necessary,  promptly  (within  the  ten  (10)  day
                              period  specified  in  subparagraph  (c)  of  this
                              Paragraph  2) make the Required  Contributions  or
                              the remainder thereof left unpaid.

                        (v)   Payments. All payments by either Shareholder under
                              this Agreement  shall be in immediately  available
                              funds  and made  directly  to  Borrower's  account
                              number   5803610284   maintained   at   Bayerische
                              Hypotheken-und  Wechselbank AG in Munich, Germany.
                              All payments by the  Shareholders  hereunder shall
                              be made without setoff,  deduction or counterclaim
                              for amounts owed to any  Shareholder  by Borrower.
                              Each  Shareholder   irrevocably   waives,  to  the
                              fullest  extent  permitted by law,  all  defenses,
                              rights of setoff and counterclaims,  which may now
                              exist or  hereafter  arise  with  respect  to such
                              payments   or   other   obligations   under   this
                              Agreement.  All payments by each Shareholder under
                              this  Agreement  shall also be made free and clear
                              of, and without withholding or deduction for or on
                              account  of, any  present  or future  taxes now or
                              hereafter  imposed on  Borrower  or its  property,
                              except  to the  extent  that such  withholding  or
                              deduction is required by applicable law.

                        (vi)  Borrower Obligations.  Borrower hereby irrevocably
                              and unconditionally agrees to either (i) authorize
                              (to the extent necessary),  issue and sell capital
                              stock  to  Shareholders,  in  connection  with any
                              Capital Contributions, or (ii) authorize and issue
                              promissory notes and any other necessary documents
                              to evidence the  Subordinated  Loans or (iii) take
                              such other action at such time as is necessary for
                              Shareholders to comply with the provisions of this
                              Paragraph 2. Neither the  obligations  of Borrower
                              under this  subparagraph  (f), any other provision
                              of this  Agreement or any other Loan  Document nor
                              the  performance  thereof  shall be a condition to
                              the obligations of Shareholders to pay to Borrower
                              the  amounts   required   under  this   Agreement;
                              provided  that  either  Shareholder's  performance
                              shall  not  constitute  a  waiver  of  any  rights
                              against Borrower.

                        (vii) Termination. The obligations of Shareholders under
                              this  Paragraph  2 shall  terminate  on January 1,
                              2001 (the "Termination  Date") except with respect
                              to any  obligation  under this  Paragraph  2 which
                              remains unsatisfied on the

SECOND AMENDED AND RESTATED LIQUIDITY UNDERTAKING - Page 6







                              Termination   Date  and  except  as   provided  in
                              subparagraph (j) and (k) below.

                        (viii)Failure to Perform; No Proof of Damages;  Specific
                              Performance.   Borrower   and   each   Shareholder
                              recognize and agree that in the event  Borrower or
                              any Shareholder fails to perform or observe any or
                              all of its obligations  under this Agreement,  and
                              if for any  reason  Agent or any Bank  shall  have
                              failed to receive when due and payable (whether at
                              stated maturity,  by  acceleration,  or otherwise)
                              the  payment  of all or any part of  principal  or
                              interest or any other  amount  payable by Borrower
                              under  the  Loan   Agreement  or  the  other  Loan
                              Documents,  then in each  such  case it  shall  be
                              assumed  conclusively  without  necessity of proof
                              that such failure by Borrower or Shareholders  was
                              the  sole  and  direct  cause of Agent or any Bank
                              failing  to   receive   such   payment   when  due
                              irrespective   of  any   other   contributing   or
                              intervening cause  whatsoever.  As a result of the
                              forgoing,  Shareholders  and Borrower  irrevocably
                              waive to the full extent  permitted by  applicable
                              law  any  right  or  defense   that   Borrower  or
                              Shareholders  may have to cause  Agent or any Bank
                              to prove the cause or amount of any  damages or to
                              mitigate  the  same.  In  addition,   and  without
                              limiting the  forgoing,  the parties  hereto agree
                              that in the  event  of such a  failure,  (i) it is
                              impossible  to measure in money the  damages  that
                              would be  suffered  by Agent and the  Banks,  (ii)
                              Agent and the Banks  will be  irreparably  damaged
                              and  (iii) any  remedy  at law will be  inadequate
                              relief and, as a result,  this Agreement  shall be
                              enforceable  by Agent  and the Banks in a court of
                              equity by a decree of specific performance without
                              the  need  of  proving  that  a  remedy  at law is
                              inadequate,  Borrower and each Shareholder  hereby
                              waiving and agreeing not to raise the defense that
                              an adequate remedy at law exists.

                        (ix)  Non-impairment  of Obligations  upon Bankruptcy of
                              Borrower.  The obligations of  Shareholders  under
                              this  Agreement  shall not be released,  impaired,
                              limited, reduced, discharged or otherwise affected
                              on   account   of  the   insolvency,   bankruptcy,
                              arrangement,     adjustment,     composi     tion,
                              liquidation,  disability,  dissolution  or lack of
                              authority of Borrower or any Shareholder,  whether
                              now   existing  or   hereafter   arising  and,  in
                              furtherance  of the  foregoing,  each  Shareholder
                              waives, to the fullest extent permitted by

SECOND AMENDED AND RESTATED LIQUIDITY UNDERTAKING - Page 7







                              applicable  law and for the  benefit  of, and as a
                              separate  undertaking  with,  Agent and the Banks,
                              any defense to the  performance  of this Agreement
                              which may be available to either  Shareholder as a
                              consequence  of Borrower not being in existence or
                              this  Agreement  being  rejected or otherwise  not
                              assumed  by  Borrower  or  any  trustee  or  other
                              similar   official   for   Borrower   or  for  any
                              substantial  part of the property of Borrower,  or
                              as a consequence of this Agreement being otherwise
                              terminated  or  modified,  in  any  bankruptcy  or
                              insolvency   proceeding  whether  such  rejection,
                              non-assumption,  termination or modification be by
                              reason  of  this  Agreement  being  held  to be an
                              executory  contract  or by  reason  of  any  other
                              circumstance;  provided  that,  if  Borrower is no
                              longer in  existence  or this  Agreement  shall be
                              rejected or otherwise  not assumed,  or terminated
                              or  modified,  each  Shareholder  agrees  for  the
                              benefit  of, and as a separate  undertaking  with,
                              Agent and the Banks, that it will unconditionally,
                              jointly and severally pay to Agent an amount equal
                              to each payment  which would  otherwise be payable
                              by  Shareholders  under or in connection with this
                              Agreement to Borrower if this  Agreement  were not
                              so  rejected  or  otherwise  not  assumed  or were
                              otherwise  not so  terminated  or  modified  (such
                              amount to be payable to Agent to be applied to the
                              indebtedness,  liabilities and  obligations  owing
                              under or pursuant to the Loan Documents (the "Loan
                              Obligations"))  and in such event,  Borrower shall
                              comply with its  obligations  under  subparagraphs
                              (f) of  this  Paragraph  2.  Shareholders  further
                              agree   that   their    obligations   under   this
                              subparagraph (i) shall continue to be effective or
                              be   reinstated   (if  a  release,   discharge  or
                              termination has occurred but only to the extent of
                              the amount discharged),  as the case may be, if at
                              any time any payment (or any part of such payment)
                              to  Agent or any Bank  previously  paid by  either
                              Shareholder  under the terms of this  subparagraph
                              (i) is rescinded or must  otherwise be restored or
                              disgorged  by Agent or any  Bank  pursuant  to any
                              bankruptcy,      insolvency,       reorganization,
                              receivership,  liquidation  or other debtor relief
                              granted to any  Shareholder  or its  successors or
                              assigns.  If, pursuant to the foregoing  sentence,
                              the   obligations  of   Shareholders   under  this
                              subparagraph (i) shall continue to be effective or
                              be   reinstated   (if  a  release,   discharge  or
                              termination  has  occurred),  any  prior  release,
                              discharge or termination from

SECOND AMENDED AND RESTATED LIQUIDITY UNDERTAKING - Page 8







                              the   terms  of  this   Agreement   given  to  any
                              Shareholder  by Agent or any Bank shall be without
                              effect.

                        (x)   No Effect or Impairment. Each Shareholder consents
                              to and  agrees  that its  obligations  under  this
                              Agreement  will also not be discharged or affected
                              by: (i) any acceptance,  forbearance or release in
                              respect of the rights of Agent or any of the Banks
                              under  the  Loan   Agreement  or  the  other  Loan
                              Documents; (ii) any waiver or release of any right
                              or option  of Agent or any of the Banks  under the
                              terms  of  the  Loan   Agreement   or  other  Loan
                              Documents;  (iii)  any  modification,   extension,
                              renewal  or  amendment  of the  terms  of the Loan
                              Agreement or other Loan  Documents;  (iv) the fact
                              that the Loan Agreement or any other Loan Document
                              shall be  invalid,  illegal or  unenforceable,  in
                              whole or in part, for any reason; or (v) except as
                              otherwise   provided  herein,  any  other  act  or
                              omission  of  any  kind  by  Agent,  any  Bank  or
                              Borrower  or  any  other  circumstance  whatsoever
                              which  might   constitute  a  legal  or  equitable
                              discharge of the Shareholders.

                        (xi)  Liquidity Report; Liquidity Level. Borrower agrees
                              to  provide  to Agent and  Shareholders,  promptly
                              upon  any   request   therefor  by  Agent  or  any
                              Shareholders,  such  information in such detail as
                              Agent or any  Shareholder  may reasonably  request
                              from time to time relating to the determination of
                              the   Liquidity   Level   from   time   to   time.
                              Furthermore,  and notwithstanding  anything to the
                              contrary contained elsewhere in this Agreement, in
                              the event that Borrower  fails to timely provide a
                              Liquidity  Report or an accurate  Liquidity Report
                              in accordance with this Agreement  within five (5)
                              days after being given  written  notice from Agent
                              to do so, then for all purposes of this Agreement,
                              the  Liquidity  Level  as of the  applicable  date
                              shall be  deemed  to be the  Liquidity  Level,  as
                              reasonably  determined  by  Agent  in good  faith,
                              specified  in a  written  notice to  Borrower  and
                              Shareholders.

      iii.  Representations  and Warranties of Shareholders.  In connection with
            this Agreement,  Shareholders hereby jointly and severally represent
            and  warrant to Agent and the Banks as follows,  provided,  however,
            that any  representation  or warranty  contained in this Paragraph 3
            made as to a  particular  Shareholder  shall be deemed  made in this
            Agreement only by such Shareholder:

                        (i)   NL  Industries is the sole  shareholder  of Kronos
                              and Kronos is the sole  shareholder  of  Borrower,
                              and  Shareholders  have received and will continue
                              to receive a direct and indirect  material benefit
                              from the making of this  Agreement,  the Loans and
                              the transactions  evidenced by and contemplated in
                              the Loan  Agreement and the other Loan  Documents;
                              this  Agreement  is  given  by   Shareholders   in
                              furtherance  of the direct and  indirect  business
                              interests and corporate  purposes of Shareholders,
                              and is  necessary to the  conduct,  promotion  and
                              attainment  of the business of  Shareholders;  and
                              the value of the consideration  received and to be
                              received  by  Shareholders  pursuant  to the  Loan
                              Agreement is reasonably  worth at least as much as
                              the liability and obligation of Shareholders under
                              this Agreement;

                        (ii)  Each  Shareholder is a corporation duly organized,
                              validly  existing and in good  standing  under the
                              laws of the jurisdiction of its  incorporation and
                              has the corporate  power and authority to execute,
                              deliver  and perform  its  obligations  under this
                              Agreement. The execution, delivery and performance
                              by each  Shareholder  of this  Agreement have been
                              duly  authorized  by all  requisite  action on the
                              part of each  Shareholder  and do not and will not
                              violate  or   conflict   with  the   articles   of
                              incorporation  or bylaws of either  Shareholder or
                              any law, rule or  regulation  or any order,  writ,
                              injunction  or decree of any  court,  governmental
                              authority or arbitrator to which such  Shareholder
                              is  subject  and do not and will not result in the
                              creation or imposition of any Lien upon any of the
                              revenues  or  assets of  either  Shareholder.  The
                              execution  and delivery of this  Agreement and the
                              performance  of and  compliance  with the terms of
                              this Agreement will not conflict with,  constitute
                              a default  (or an event which with notice or lapse
                              of time or both would constitute a default) under,
                              or result in the breach of, any material contract,
                              agreement  or  other   instrument   to  which  any
                              Shareholder  is a party or which may be applicable
                              to any Shareholder or any of its assets;

                        (iii) This  Agreement,  when  executed and  delivered by
                              each Shareholder and Borrower, will constitute the
                              joint and  several  and valid,  legal and  binding
                              obligation  of  each  Shareholder  enforceable  in
                              accordance  with its  terms,  except to the extent
                              that enforcement may be limited by

SECOND AMENDED AND RESTATED LIQUIDITY UNDERTAKING - Page 10







                              bankruptcy, insolvency, reorganization, moratorium
                              or other similar laws affecting the enforcement of
                              creditors'  rights  generally and by principles of
                              equity;

                        (iv)  As of the date of this Agreement, and after giving
                              effect  to  this   Agreement  and  the  contingent
                              obligations  evidenced  by  this  Agreement,  each
                              Shareholder is not, and will not be, insolvent (as
                              such  term is used or  defined  in all  applicable
                              bankruptcy,   fraudulent   transfer,   insolvency,
                              fraudulent  conveyance and similar laws), and each
                              Shareholder has and will have assets which, fairly
                              valued,  exceed its indebtedness,  liabilities and
                              obligations;

                        (v)   All corporate acts and  conditions  required to be
                              performed and satisfied prior to the execution and
                              delivery of this Agreement, and to constitute this
                              Agreement  as the valid,  binding and  enforceable
                              obligation of each  Shareholder in accordance with
                              its terms,  except to the extent that  enforcement
                              may  be   limited   by   bankruptcy,   insolvency,
                              reorganization,  moratorium  or other similar laws
                              affecting the  enforcement  of  creditors'  rights
                              generally and by  principles of equity,  have been
                              performed  and  satisfied in  accordance  with all
                              applicable laws;

                        (vi)  Each   Shareholder   is  familiar  with,  and  has
                              independently    reviewed    books   and   records
                              regarding, the financial condition of Borrower and
                              is  familiar   with  the  value  of  any  and  all
                              Collateral  and  other   collateral  and  security
                              intended  to secure or to be created to secure the
                              Loans;   however,  each  of  Shareholders  is  not
                              relying  on  such  financial   condition  or  such
                              Collateral,   collateral   or   security   as   an
                              inducement to enter into this Agreement; and

                        (vii) Except for the execution of the Loan  Agreement by
                              Agent and Majority  Banks,  neither Agent,  any of
                              the  Banks  nor any  other  Person  has  made  any
                              representation,   warranty  or  statement  to,  or
                              promise,   covenant   or   agreement   with,   any
                              Shareholder  in order to  induce  Shareholders  to
                              execute this Agreement.

      iv.   Representations and Warranties of Borrower.  In connection with this
            Agreement,  Borrower hereby represents and warrants to Shareholders,
            Agent and the Banks as follows:


SECOND AMENDED AND RESTATED LIQUIDITY UNDERTAKING - Page 11







                        (i)   Borrower is a corporation duly organized,  validly
                              existing  and in good  standing  under the laws of
                              the  jurisdiction  of its  incorporation,  has all
                              requisite corporate power and authority to own its
                              assets and carry on its  business  as now being or
                              as proposed to be conducted, and has the corporate
                              power  and  authority  to  execute,   deliver  and
                              perform its obligations under this Agreement;

                        (ii)  The   execution,   delivery  and   performance  by
                              Borrower   of  this   Agreement   have  been  duly
                              authorized by all requisite  action on the part of
                              Borrower  and do  not  and  will  not  violate  or
                              conflict  with the  articles of  incorporation  or
                              bylaws of Borrower or any law,  rule or regulation
                              or any order,  writ,  injunction  or decree of any
                              court,  governmental  authority or  arbitrator  to
                              which Borrower is subject, and do not and will not
                              result in the creation or  imposition  of any lien
                              upon any of the  revenues  or assets of  Borrower.
                              The execution  and delivery of this  Agreement and
                              the  performance of and compliance  with the terms
                              of  this   Agreement   will  not  conflict   with,
                              constitute  a  default  (or an  event  which  with
                              notice or lapse of time or both would constitute a
                              default)  under,  or result in the  breach of, any
                              material  contract,  agreement or other instrument
                              to  which  Borrower  is a party  or  which  may be
                              applicable to Borrower or any of its assets;

                        (iii) This  Agreement,  when  executed and  delivered by
                              each Shareholder and Borrower, will constitute the
                              valid,  legal and binding  obligation  of Borrower
                              enforceable in accordance  with its terms,  except
                              to the extent that  enforcement  may be limited by
                              bankruptcy, insolvency, reorganization, moratorium
                              or other similar laws affecting the enforcement of
                              creditors'  rights  generally and by principles of
                              equity; and

                        (iv)  All corporate acts and  conditions  required to be
                              performed and satisfied prior to the execution and
                              delivery of this Agreement, and to constitute this
                              Agreement  as the valid,  binding and  enforceable
                              obligation  of  Borrower  in  accordance  with its
                              terms,  except to the extent that  enforcement may
                              be    limited    by    bankruptcy,     insolvency,
                              reorganization,  moratorium  or other similar laws
                              affecting the  enforcement  of  creditors'  rights
                              generally and by

SECOND AMENDED AND RESTATED LIQUIDITY UNDERTAKING - Page 12







                              principles  of  equity,  have been  performed  and
                              satisfied in accordance with all applicable laws.

      v.    Cumulative Remedies; No Election.  The rights of Agent and the Banks
            under this Agreement shall be cumulative of any and all other rights
            that Agent and the Banks may ever have  against any  Shareholder  or
            Borrower  or  arising  under  the  Loan  Documents,  or at law or in
            equity.  The  exercise  by Agent or any Bank of any  right or remedy
            under this Agreement or under any other Loan Document,  or at law or
            in equity,  shall not preclude the concurrent or subsequent exercise
            of any other right or remedy.  This  Agreement  may be enforced from
            time to time as often as  occasion  therefor  may  arise,  and it is
            agreed  that it shall not be  necessary  for  Agent or any Bank,  in
            order to enforce the provisions of this Agreement, first to exercise
            any rights against Borrower,  any Shareholder or any other Person or
            institute suit or to exhaust any available remedies against security
            in its  possession  or under its control,  or to resort to any other
            sources or means of obtaining  payment of the Loans. The obligations
            and duties of  Shareholders  under this Agreement are independent of
            the  obligations  and duties of Borrower under the Loan Agreement or
            this Agreement,  and a separate action or actions may be brought and
            prosecuted  against  Shareholders  or either of them, on a joint and
            several basis,  whether or not action is brought against Borrower or
            any other Person obligated in respect of the Loan and whether or not
            Borrower is joined in any such action or actions. In furtherance and
            not in limitation of the foregoing, the obligations and duties of NL
            Industries  under this Agreement are  independent of the obligations
            and duties of NL Industries under the NL Guaranty,  payments made by
            NL Industries under the terms of this Agreement will not be credited
            against  payments made or required to be made under the NL Guaranty,
            payments  made by NL  Industries  under the NL Guaranty  will not be
            credited  against payments made or required to be made hereunder and
            the  rights  of  Agent  and  the  Banks  under  this  Agreement  are
            cumulative  of all  rights  Agent and the Banks may have  against NL
            Industries under the NL Guaranty.

      vi.   Binding Effect. This Agreement is for the benefit of Borrower, Agent
            and the Banks, and their successors and assigns, and in the event of
            an assignment by Agent or any Bank,  its  successors or assigns,  of
            the Loans,  or any part of the Loans,  the rights and benefits under
            this  Agreement,  to the  extent  applicable  to  the  indebtedness,
            liabilities  and  obligations so assigned,  may be transferred  with
            such  indebtedness,  liabilities and obligations.  This Agreement is
            binding,  not only upon  Shareholders  and Borrower,  but upon their
            respective  successors and assigns;  provided that neither  Borrower
            nor any  Shareholder  may assign  any of its  rights or  obligations
            hereunder without the prior written consent of the Majority Banks.

      vii.  Right of Setoff.  With respect to all  obligations  of  Shareholders
            hereunder owed to Agent or the Banks, each Shareholder hereby grants
            to Agent and the Banks a right of  setoff  upon any and all  monies,
            securities or other property of

SECOND AMENDED AND RESTATED LIQUIDITY UNDERTAKING - Page 13







            such Shareholder,  and the proceeds therefrom, now or hereafter held
            or  received  by or in  transit to Agent or any Bank from or for the
            account  of such  Shareholder,  whether  for  safekeeping,  custody,
            pledge, transmission, collection or otherwise, and also upon any and
            all deposits  (general or special) and credits of such  Shareholder,
            and any and all  claims  of such  Shareholder  against  Agent or any
            Banks at any time existing.

      viii. Further  Assurances.  Upon the  reasonable  request  of Agent,  each
            Shareholder  will,  at any time and from time to time,  duly execute
            and deliver to Agent any and all such further agreements,  documents
            and instruments,  and supply such additional information,  as may be
            necessary  or  advisable,  in the  reasonable  opinion of Agent,  to
            obtain the full benefits of this Agreement,  provided, however, that
            delivery of such additional  information is subject to receipt of an
            executed  Confidentiality  Agreement  with  respect to  confidential
            information of any Shareholder or any Person Controlled  directly or
            indirectly by such Shareholder.

      ix.   Invalid Provisions. If any provision of this Agreement is held to be
            illegal,  invalid or  unenforceable  under  present  or future  laws
            effective during the term of this Agreement, such provision shall be
            fully  severable,  this Agreement shall be construed and enforced as
            if such  illegal,  invalid  or  unenforceable  provision  had  never
            comprised a part of this Agreement,  and the remaining provisions of
            this  Agreement  shall remain in full force and effect and shall not
            be affected by the illegal, invalid or unenforceable provision or by
            its  severance  from this  Agreement.  Furthermore,  in lieu of such
            illegal,  invalid or  unenforceable  provision  there shall be added
            automatically  as a part of this Agreement a provision as similar in
            terms to such illegal,  invalid or unenforceable provision as may be
            possible and be legal, valid and enforceable.

      x.    Modification  in Writing.  No  modification,  consent,  amendment or
            waiver of any  provision  of this  Agreement,  and no consent to any
            departure  by any  Shareholder  or  Borrower  from the terms of this
            Agreement,  shall be  effective  unless the same shall be in writing
            and signed by the Majority Banks and then shall be effective only in
            the specific  instance and for the specific purpose for which given;
            provided  that no  amendment,  waiver or other  modification  of, or
            consent to any departure from, the provisions of Paragraph 2 of this
            Agreement or this  Paragraph  10 shall be effective  unless the same
            shall  be in  writing  and  signed  by Banks  who hold at least  80%
            (eighty  percent) of the aggregate  unpaid  principal  amount of the
            Loans.

      xi.   No Waiver,  Etc.  No notice to or demand on any  Shareholder  in any
            case  shall,  of itself,  entitle  any  Shareholder  to any other or
            further notice or demand in similar or other circumstances. No delay
            or  omission by Agent or any Bank in  exercising  any power or right
            under  this  Agreement  shall  impair  any such power or right or be
            construed as a waiver thereof or any acquiescence therein, and no

SECOND AMENDED AND RESTATED LIQUIDITY UNDERTAKING - Page 14







            single or partial exercise of any such power or right shall preclude

Borrower the principal amount of DM 1,600,000,000 (Deutsche Mark One Billion Six
Hundred  Million) (the aggregate of any and all amounts advanced by the Banks or
their  predecessors  in interest  under the Loan  Agreement,  the First Restated
Agreement and/or the Original  Agreement and outstanding at any time,  including
without limitation any and all amounts outstanding under the Term Portion or the
Revolving  Portion  (as  such  terms  are  defined  in the Loan  Agreement),  is
hereinafter called the "Loans"); and

      WHEREAS,  in order to  induce  the Banks to amend  and  restate  the First
Restated  Agreement,  the Guarantor is required to guarantee the prompt  payment
when due of all principal,  interest and other amounts that shall be at any time
payable by the Borrower or any of its  Subsidiaries  under the Loan Documents on
the terms and conditions set forth in this Guaranty;

      NOW  THEREFORE,  for and in  consideration  of the above,  and any and all
financial accommodations or extensions of credit (including, without limitation,
any loan or advance by  renewal,  refinancing  or  extension  of the  agreements
described herein) heretofore, now or hereafter made to or for the benefit of the
Borrower and/or Kronos Titan by the Banks,  the Guarantor  hereto  covenants and
agrees as follows:


                                      1





                                   ARTICLE I

                                 The Guaranty

      SECTION 1.1 The Guaranty. The Guarantor hereby unconditionally  guarantees
to the  Agent and the Banks and their  respective  successors  and  assigns  the
punctual payment, as and when due (whether by acceleration or otherwise), of

            (i)  The  principal  amount  of  the  Loans  and  all  interest  and
prepayment and other charges accruing thereunder;

            (ii) All charges,  payments,  and other  obligations of the Borrower
and/or  Kronos  Titan  accruing  under the Loan  Agreement,  the First  Restated
Agreement and/or the Original Agreement; and

            (iii) All charges,  payments and other  obligations of the Borrower,
Kronos Titan and/or any of the Subsidiaries of the Borrower  accruing under this
Guaranty or any of the other Loan Documents (all of the foregoing, collectively,
the "Secured Indebtedness").

      Upon failure by the Borrower,  Kronos Titan and/or any of the Subsidiaries
of the Borrower to pay punctually any such amount,  the Guarantor agrees that it
will  forthwith  on demand  pay the  amount  not so paid at the place and in the
manner specified in the Loan Documents or as otherwise notified to the Guarantor
by the Agent.

      SECTION  1.2  Guarantor's  Obligation.   The  Guarantor  agrees  that  its
liability  hereunder  shall be as a sole and  primary  obligor and not merely as
surety and that its  liability is absolute and  unconditional,  and shall not be
subject to any right of set-off or  counterclaim  and shall remain in full force
and effect until the entire Secured Indebtedness shall have been paid in full.

      SECTION 1.3 Waiver.  The Guarantor  hereby  waives,  to the fullest extent
permitted  by law,  notice of the  acceptance  hereof,  diligence,  presentment,
demand of payment or  otherwise,  and any right to  require a  proceeding  first
against the Borrower,  Kronos Titan and/or any other Person  (including  without
limitation any other Guarantor).

      SECTION 1.4 No Effect or Impairment.  The Guarantor hereby consents to and
agrees  that its  obligations  under this  Guaranty  will not be  discharged  or
affected by: (i) any acceptance, forbearance or release in respect of the rights
of the Agent or the Banks or any  subsequent  holder under the Loan Agreement or
the Loan Documents,  including,  without  limitation,  any release of any of the
Collateral or any other guaranty of the Loans; (ii) any waiver or release of any
right or option of the Agent or the  Banks or any  subsequent  holder  under the
terms  of the  Loan  Agreement  or  other  Loan  Documents,  including,  without
limitation,  any release of any of the  Collateral or any other  guaranty of the
Loans; (iii) any modification,  extension,  renewal or amendment of the terms of
the  Loan  Agreement  or other  Loan  Documents;  (iv)  the  fact  that the Loan
Agreement   or  any  other  Loan   Documents   shall  be  invalid,   illegal  or
unenforceable,  in  whole  or in  part,  for any  reason;  (v) the  receipt  and
acceptance of notes, checks or other instruments for

                                      2





the payment of money by the  Borrower,  Kronos Titan and/or any  Subsidiary  and
extensions and renewals  thereof;  or (vi) except as otherwise  provided herein,
any  other  act or  omission  of any  kind  by the  Agent  or the  Banks  or any
subsequent  holder or the  Borrower  or Kronos  Titan or any other  circumstance
whatsoever  which  might  constitute  a  legal  or  equitable  discharge  of the
Guarantor, including, without limitation, the bankruptcy of the Borrower, Kronos
Titan and/or any Subsidiary.

      SECTION 1.5  Payments.  All payments  provided for herein shall be made in
immediately  available funds in Deutsche Mark ("DM");  provided,  however,  that
payments  provided for herein shall be made in  immediately  available  funds in
U.S.  Dollars if and to the extent that the payment  provided for herein relates
to an amount payable by the Borrower  and/or Kronos Titan in U.S.  Dollars.  The
obligation  of the  Guarantor to make payment in DM of any amounts due hereunder
to the Agent shall not be discharged or satisfied by any tender, or any recovery
pursuant to any judgment,  which is expressed in or converted  into any currency
other than DM, except to the extent that such tender or recovery shall result in
the actual receipt by the Agent of the full amount of DM expressed to be due and
owing in respect of the  principal  amount of and interest  accrued on the Loans
and in regard to the other parts of the Secured  Indebtedness  expressed  in DM.
The Guarantor  agrees that the  obligations  to make payments in DM as aforesaid
shall be enforceable  as an  alternative  or additional  cause of action for the
purpose of recovery  in DM of the amount (if any) by which such  actual  receipt
shall fall short of the full amount of DM  expressed to be payable in respect of
any  amount due  hereunder,  and shall not be  affected  by any  judgment  being
obtained for other sums in any other currency in enforcement of this Guaranty.

      SECTION  1.6 Net  Payments.  All  payments  by the  Guarantor  under  this
Agreement  shall be made without setoff or  counterclaim  and free and clear of,
and without withholding or deduction for or on account of, any present or future
taxes (other than Excluded  Taxes) now or hereafter  imposed on the recipient of
such payment or its income, property, assets or franchises, except to the extent
that such withholding or deduction is required by applicable law or is permitted
under the Loan Agreement.

      If any such  withholding  or deduction is required by applicable law or is
permitted under the Loan Agreement, the Guarantor will:

            (i) pay to the relevant tax  authorities the full amount so required
to be withheld or deducted  when and as the same shall become due and payable to
such tax authorities;

            (ii) promptly forward to the Agent and each of the affected Banks an
official  receipt or other  documentation  satisfactory to the Agent  evidencing
such payment to such tax authorities; and

            (iii) except to the extent that such withholding or deduction is for
Excluded Taxes or, under the terms of the Loan Agreement, for additional amounts
which are not payable or have been  waived,  pay to the Agent for the account of
the relevant recipient such additional amount as is necessary to ensure that the
net amount actually received by each recipient will equal

                                      3





the full amount such  recipient  would have received had no such  withholding or
deduction been required.

      SECTION 1.7  Subrogation.  The Guarantor  shall not have any right to, and
will not,  exercise any rights that it may acquire by way of  subrogation  under
this Guaranty (by any payment made hereunder or otherwise) until all the Secured
Indebtedness  shall have been paid in full.  If any amount  shall be paid to the
Guarantor on account of such subrogation rights at any time when all the Secured
Indebtedness  shall  not have been paid in full,  such  amount  shall be held in
trust for the benefit of the Agent and the Banks and shall  forthwith be paid to
the Agent to be credited and applied to the payment of the Secured Indebtedness,
whether  matured  or  unmatured,  in  accordance  with  the  terms  of the  Loan
Agreement.  If (i) all the Secured Indebtedness shall be paid in full, the Agent
and the Banks  will,  at the  Guarantor's  request,  execute  and deliver to the
Guarantor appropriate documents,  without recourse and without representation or
warranty,  necessary to evidence the transfer by subrogation to the Guarantor of
an interest  in the  Secured  Indebtedness  resulting  from such  payment by the
Guarantor.

      SECTION  1.8  Revival of  Obligation.  If,  after the Agent's or the other
Banks'  receipt  of any  payment  from  the  Borrower  of all or any part of the
amounts  paid  under this  Guaranty,  or after the  Agent's or the other  Banks'
collection of the proceeds  from the sale of any  Collateral or from the payment
under any other guaranty,  the Agent or the Banks are petitioned or compelled to
return any such  payment or  proceeds,  because  such  payment  or  proceeds  is
invalidated,  declared fraudulent,  set aside, determined to be void or voidable
as a preference, an impermissible setoff, or for any reason whatsoever, then the
Borrower's obligations (and Kronos Titan's obligations,  if applicable) shall be
deemed to be revived and this Guaranty  shall  continue in full force as if such
payment  or  proceeds  had not been  received  by the Agent or the  Banks  until
payment in full is made by the Guarantor.  In addition,  the Guarantor agrees to
indemnify and hold the Agent and the Banks harmless from and against and for any
and all  damages,  losses,  costs or  expenses  (including  without  limitation,
reasonable  attorneys'  fees) incurred by them in connection with such surrender
or return.

                                  ARTICLE II

                           Jurisdiction and Service

      SECTION 2.1 Consent to Jurisdiction,  Venue. The Guarantor  represents and
warrants  that it is not  entitled to immunity  from  judicial  proceedings  and
agrees  that,  should  the Agent  bring any suit,  action or  proceeding  in the
jurisdiction  described  below to enforce any  obligation  or  liability  of the
Guarantor under this Guaranty,  no immunity from such suit, action or proceeding
will be claimed by or on behalf of the  Guarantor  or with respect to its assets
or  property.  The  Guarantor  irrevocably  submits to the  jurisdiction  of any
federal or state court sitting in the City of New York, State of New York, or in
the City of Dallas,  State of Texas, over any suit, action or proceeding arising
out of or relating to this Guaranty.  The Guarantor  irrevocably  waives, to the
fullest  extent  permitted by law, any  objection  which it has or may hereafter
have to the laying of the venue of any such suit,  action or proceeding  brought
in such court and any claim that any such suit, action or proceeding  brought in
such court has been

                                      4





brought  in  an  inconvenient   forum.  The  Guarantor  agrees  that  final  and
non-appealable judgment in any such suit, action or proceeding brought in such a
court shall be conclusive  and binding upon the Guarantor and may be enforced in
any other courts to the jurisdiction of which the Guarantor is subject by a suit
upon such  judgment,  provided  that  service of process  is  effected  upon the
Guarantor  in one of the manners  specified in Section 2.3 below or as otherwise
permitted by law.

      SECTION  2.2  Appointment  of  Agent.  The  Guarantor  hereby  irrevocably
designates  and  appoints  The  Prentice-Hall   Corporation  System,  Inc.,  c/o
Corporation Service Company, 500 Central Avenue,  Albany, New York 12206, as its
authorized  agent to accept and acknowledge on its behalf service of any and all
process  which may be served in any suit,  action or  proceeding  of the  nature
referred to in Section 2.1 in any court  sitting in The City of New York,  State
of New York. Said  designation and  appointment  shall be irrevocable  until the
Secured  Indebtedness  shall have been paid in full.  If such agent for  service
shall  cease  so to act,  the  Guarantor  covenants  and  agrees  that it  shall
irrevocably  designate and appoint without delay another such agent satisfactory
to the Agent and shall deliver promptly to the Agent evidence in writing of such
other agent's acceptance of such appointment.

      SECTION 2.3 Service of Process.  The Guarantor  hereby consents to process
being  served in any suit,  action or  proceeding  of the nature  referred to in
Section  2.1 either  (a) by the  mailing of a copy  thereof by  registered  mail
(registered  airmail  if  addressed  to a location  in a country  other than the
country of mailing),  postage prepaid,  return receipt requested, to the address
for the Guarantor set forth on the signature page hereof or to any other address
of which the Guarantor  shall have given written  notice to Agent or such holder
or (b) by serving a copy  thereof  upon The  Prentice-Hall  Corporation  System,
Inc., c/o Corporation  Service  Company,  500 Central Avenue,  Albany,  New York
12206,  as the Guarantor's  agent for service of process  (provided that, to the
extent  lawful and possible,  written  notice of said service upon said agent of
the  Guarantor  shall be  mailed  by  registered  mail  (registered  airmail  if
addressed to a location in a country other than the country of mailing), postage
prepaid,  return receipt  requested,  to the Guarantor at its address  specified
above or to any other  address of which the  Guarantor  shall have given written
notice to the Agent.  The Guarantor  irrevocably  waives,  to the fullest extent
permitted by law, all claim of error by reason of any such service (but does not
waive any right to assert lack of subject matter  jurisdiction)  and agrees that
such service (i) shall be deemed in every respect  effective  service of process
upon the Guarantor in any such suit, action or proceeding and (ii) shall, to the
fullest extent  permitted by law, be taken and held to be valid personal service
upon and personal delivery to the Guarantor.

      SECTION 2.4 No Limitation on Service or Suit. Nothing in Sections 2.1, 2.2
or 2.3 above shall affect the right of the Agent to serve  process in any manner
permitted  by law or limit  the  right of the  Agent  or other  holder  to bring
proceedings against the Guarantor in the courts of any other jurisdiction.


                                      5

of  any  amount  payable  by  the  Borrower,  Kronos  Titan  and/or  any  of the
Subsidiaries  of the  Borrower  under  the Loan  Documents  is  stayed  upon the
insolvency,  bankruptcy or reorganization  of the Borrower,  Kronos Titan and/or
any such Subsidiary,  all such amounts otherwise  subject to acceleration  under
the terms of the Loan  Documents  shall  nonetheless be payable by the Guarantor
hereunder forthwith on demand by the Agent.

state law.

any breach of any term,  covenant,  representation or warranty  contained in the
instruments  evidencing the Loans, the Loan Agreement,  this Guaranty, or any of

construed as a further or continuing  waiver of any such  condition or breach or
waiver of any other  condition  or of any  breach of any other  term,  covenant,
representation  or warranty  thereof;  nor shall any single or partial  exercise
thereof  preclude any other or further  exercise  thereof or the exercise of any

reimburse  the  Agent  for all  reasonable  out-of-pocket  costs  and  expenses,
including  without  limitation  reasonable  attorneys'  fees  and  court  costs,
incurred by the Agent in enforcing this Guaranty, and the Guarantor acknowledges
and agrees that all such sums to be so reimbursed by it to the Agent are part of
the Secured Indebtedness.

      SECTION 3.15 Limitation of Special Damages.  The Guarantor hereby releases
each of the Agent and all of the Banks from any liability  for, and waives,  and
agrees not to claim or sue for any special,  indirect or consequential  damages,
suffered by the undersigned,  in connection with any claim (whether  sounding in
tort, contract or otherwise) in any way arising out of, related to, or connected
with  the  Loan  Documents,  whether  such  claim is  asserted  before  or after
repayment in full of all of the Borrower's  and/or Kronos Titan's  indebtedness,
liabilities and obligations. This waiver shall inure to the benefit of the Agent
and the Banks and their  respective  successors and assigns and shall be binding
on the Guarantor and its successors and assigns.

(a) Each Lender shall make each Loan to be made by it hereunder on the proposed date thereof by wire transfer of immediately available funds by 1:00 p.m., New York City time, to the account of the Administrative Agent most recently designated by it for such purpose by notice to the Lenders. The Administrative Agent will make such Loans available to the Borrower by promptly crediting the amounts so received, in like funds, to an account of the Borrower maintained with the Administrative Agent in New York City and designated by the Borrower in the applicable Borrowing Request; provided that Revolving Credit Base Rate Loans made to finance the reimbursement of an LC Disbursement under any Letter of Credit as provided in Section 2.04(e) shall be remitted by the Administrative Agent to the LC Issuing Lender. (b) Unless the Administrative Agent shall have received notice from a Lender prior to the proposed date of any Borrowing that such Lender will not make available to the Administrative Agent such Lender's share of such Borrowing, the Administrative Agent may assume that such Lender has made such share available on such date in accordance with paragraph (a) of this Section 2.05 and may, in reliance upon such assumption, make available to the Borrower a corresponding amount. In such event, if a Lender has not in fact made its share of the applicable Borrowing available to the Administrative Agent, then the applicable Lender and the Borrower severally agree to pay to the Administrative Agent forthwith on demand such corresponding amount with interest thereon, for each day from and including the date such amount is made available to the Borrower to but excluding the date of payment to the Administrative Agent, at (i) in the case of such Lender, the Federal Funds Effective Rate or (ii) in the case of the Borrower, the interest rate applicable to Base Rate Loans. If such Lender pays such amount to the Administrative Agent, then such amount shall constitute such Lender's Loan included in such Borrowing. Credit Agreement - 35 - SECTION 2.06. Interest Elections. (a) Each Borrowing initially shall be of the Type specified in the applicable Borrowing Request and, in the case of a Eurodollar Borrowing, shall have an initial Interest Period as specified in such Borrowing Request. Thereafter, the Borrower may elect to convert such Borrowing to a different Type or to continue such Borrowing and, in the case of a Eurodollar Borrowing, may elect Interest Periods therefor, all as provided in this Section 2.06. The Borrower may elect different options for continuations and conversions with respect to different portions of the affected Borrowing, in which case each such portion shall be allocated ratably among the Lenders holding the Loans comprising such Borrowing, and the Loans comprising each such portion shall be considered a separate Borrowing. (b) To make an election pursuant to this Section 2.06, the Borrower shall notify the Administrative Agent of such election by telephone by the time that a Borrowing Request would be required under Section 2.03 if the Borrower were requesting a Borrowing of the Type resulting from such election to be made on the effective date of such election. Each such telephonic Interest Election Request shall be irrevocable and shall be confirmed promptly by hand delivery or telecopy to the Administrative Agent of a written Interest Election Request in a form approved by the Administrative Agent and signed by the Borrower. (c) Each telephonic and written Interest Election Request shall specify the following information in compliance with Section 2.02: (i) the Borrowing to which such Interest Election Request applies and, if different options for continuations or conversions are being elected with respect to different portions thereof, the portions thereof to be allocated to each resulting Borrowing (in which case the information to be specified pursuant to clauses (iii) and (iv) below shall be specified for each resulting Borrowing); (ii) the effective date of the election made pursuant to such Interest Election Request, which shall be a Business Day; (iii) whether the resulting Borrowing is to be a Base Rate Borrowing or a Eurodollar Borrowing; and (iv) if the resulting Borrowing is a Eurodollar Borrowing, the Interest Period to be applicable thereto after giving effect to such election, which shall be a period contemplated by the definition of the term "Interest Period". If any such Interest Election Request requests a Eurodollar Borrowing but does not specify an Interest Period, then the Borrower shall be deemed to have selected an Interest Period of one month's duration. Credit Agreement - 36 - (d) Promptly following receipt of an Interest Election Request, the Administrative Agent shall advise each affected Lender of the details thereof and of such Lender's portion of each resulting Borrowing. (e) If the Borrower fails to deliver a timely Interest Election Request with respect to a Eurodollar Borrowing prior to the end of the Interest Period applicable thereto, then, unless such Borrowing is repaid as provided herein, at the end of such Interest Period such Borrowing shall be converted to a Base Rate Borrowing. Notwithstanding any contrary provision hereof, if an Event of Default has occurred and is continuing and the Administrative Agent, at the request of the Required Lenders, so notifies the Borrower, then, so long as an Event of Default is continuing (i) no outstanding Borrowing may be converted to or continued as a Eurodollar Borrowing and (ii) unless repaid, each Eurodollar Borrowing shall be converted to a Base Rate Borrowing at the end of the Interest Period applicable thereto. SECTION 2.07. Termination and Reduction of Commitments. (a) Unless previously terminated, (i) the Revolving Credit Commitments shall terminate at the close of business on the Final Maturity Date and (ii) the Term Loan Commitments shall terminate at the close of business on the Term Loan Commitment Termination Date. (b) The Borrower may at any time terminate, or from time to time reduce, the Commitments of any Class; provided that (i) each reduction of the Commitments of such Class shall be in an amount that at least equal to $1,000,000 or any greater integral multiple of $500,000, (ii) the Borrower shall not terminate or reduce the Term Loan Commitments if, after giving effect to any concurrent prepayment of Term Loans in accordance with Section 2.09, the outstanding Term Loans would exceed the total Term Loan Commitments and (iii) the Borrower shall not terminate or reduce the Revolving Credit Commitments if, after giving effect to any concurrent prepayment of the Revolving Credit Loans in accordance with Section 2.09, the total Revolving Credit Exposures would exceed the total Revolving Credit Commitments. (c) The Borrower shall notify the Administrative Agent of any election to terminate or reduce Commitments under paragraph (b) of this Section 2.07 at least three Business Days prior to the effective date of such termination or reduction, specifying such election and the effective date thereof. Promptly following receipt of any such notice, the Administrative Agent shall advise the Lenders of the contents thereof. Each notice delivered by the Borrower pursuant to this Section 2.07 shall be irrevocable; provided that a notice of termination of Commitments delivered by the Borrower may state that such notice is conditioned upon the effectiveness of other credit facilities, in which case such notice may be revoked by the Borrower (by notice to the Administrative Agent on or prior to the specified effective date) if such condition is not satisfied. Any termination or reduction of Commitments shall be permanent. Each reduction of Commitments of any Class shall be Credit Agreement - 37 - made ratably among the Lenders in accordance with their respective Commitments of such Class. SECTION 2.08. Repayment of Loans; Evidence of Debt. (a) The Borrower hereby unconditionally promises to pay to the Administrative Agent for the account of each Revolving Credit Lender the then unpaid principal amount of such Lender's Revolving Credit Loans on the Final Maturity Date.

Credit Agreement - 38 - (c) Each Lender shall maintain in accordance with its usual practice an account or accounts evidencing the indebtedness of the Borrower to such Lender resulting from each Loan made by such Lender, including the amounts of principal and interest payable and paid to such Lender from time to time hereunder. (d) The Administrative Agent shall maintain accounts in which it shall record (i) the amount of each Loan made hereunder, the Class and Type thereof and the Interest Period applicable thereto, (ii) the amount of any principal or interest due and payable or to become due and payable from the Borrower to each Lender hereunder and (iii) the amount of any sum received by the Administrative Agent hereunder for the account of the Lenders and each Lender's share thereof. (e) The entries made in the accounts maintained pursuant to paragraph (c) or (d) of this Section 2.08 shall be prima facie evidence of the existence and amounts of the obligations recorded therein; provided that the failure of any Lender or the Administrative Agent to maintain such accounts or any error therein shall not in any manner affect the obligation of the Borrower to repay the Loans in accordance with the terms of this Agreement. (f) Any Lender may request that Loans of any Class made by it be evidenced by a promissory note. In such event, the Borrower shall prepare, execute and deliver to such Lender a promissory note payable to the order of such Lender (or, if requested by such Lender, to such Lender and its registered assigns) and in a form reasonably acceptable to the Administrative Agent. Thereafter, the Loans of such Class evidenced by such promissory note and interest thereon shall at all times (including after assignment pursuant to Section 10.04) be represented by one or more promissory notes in such form payable to the order of the payee named therein (or, if such promissory note is a registered note, to such payee and its registered assigns). SECTION 2.09. Prepayment of Loans. (a) Optional Prepayments. The Borrower shall have the right at any time and from time to time to prepay any Borrowing in whole or in part, subject to prior notice in accordance with paragraph (c) of this Section 2.09.

Upon request by the Borrower, the Administrative Agent shall (unless a Default shall have occurred and be continuing) release the Net Available Proceeds to the Borrower in an amount not exceeding the amount required for repair or replacement of the property for which such Net Available Proceeds were received; provided that if such Net Available Proceeds have not been released or committed to be expended in respect of such repair or replacement in an amount and manner reasonably acceptable to the Administrative Agent within 180 days of receipt by the Borrower or such Subsidiary, as the case may be, such Net Available Proceeds, to the extent that such Net Available Proceeds, together with all other Net Available Proceeds received by the Borrower or any Subsidiary in respect of Casualty Events, not released or committed to be expended in respect of repair or replacement within 180 days of receipt by the Borrower or any Subsidiary exceeds $500,000, shall be used to prepay the Loans (and/or provide cover for LC Exposure as specified in Section 2.04(i)) and automatically reduce the Revolving Credit Commitments in an aggregate amount, if any, equal to 100% of the Net Available Proceeds of such Casualty Event not theretofore applied to the repair or replacement of such property (such prepayment and reduction to be effected in each case in the manner and to the extent specified in clause (vi) of this Section 2.09).

Without limiting the obligation of the Borrower to obtain the consent of the Required Lenders to any Disposition not otherwise permitted hereunder, the Borrower agrees, on or prior to the occurrence of any Disposition which, together with the aggregate Net Available Proceeds of all other Dispositions to date in the then current fiscal year, would generate Net Available Proceeds in excess of $100,000 to deliver to the Administrative Agent a statement certified by a Financial Officer, in form and detail reasonably satisfactory to the Administrative Agent, of the estimated amount of the Net Available Proceeds of such Disposition that will (on the date of such Disposition) be received by the Borrower or any Subsidiary in cash and the Borrower will prepay the Loans hereunder (and provide cover for LC Exposure as specified in Section 2.04(i)), and the Commitments hereunder shall be subject to automatic reduction, as follows: (x) upon the date of such Disposition, in an aggregate amount equal to 100% of the amount of the Net Available Proceeds of such Disposition which, Credit Agreement - 40 - together with the aggregate Net Available Proceeds of all other Dispositions to date in the then current fiscal year, would generate Net Available Proceeds in excess of $100,000, to the extent received by the Borrower or any of its Subsidiaries in cash on the date of such Disposition; and (y) thereafter, quarterly, on the date of the delivery by the Borrower to the Administrative Agent pursuant to Section 6.01 of the financial statements for any quarterly fiscal period or fiscal year, to the extent the Borrower or any Subsidiary shall receive Net Available Proceeds during the quarterly fiscal period ending on the date of such financial statements in cash under deferred payment arrangements or Disposition Investments entered into or received in connection with any Disposition, an amount equal to (A) 100% of the aggregate amount of such Net Available Proceeds received during such quarterly fiscal period minus (B) any transaction expenses associated with Dispositions and not previously deducted in the determination of Net Available Proceeds plus (or minus, as the case may be) (C) any other adjustment received or paid by the Borrower or any Subsidiary pursuant to the respective agreements giving rise to Dispositions and not previously taken into account in the determination of the Net Available Proceeds of Dispositions, provided that if prior to the date upon which the Borrower would otherwise be required to make a prepayment under this clause (y) with respect to any quarterly fiscal period the aggregate amount of such Net Available Proceeds (after giving effect to the adjustments provided for in this clause (y)) shall exceed $1,000,000, then the Borrower shall within three Business Days after receipt of such aggregate amount make a prepayment under this clause (y) in an amount equal to such required prepayment. Prepayments of Loans (and cover for LC Exposure) and reductions of Commitments shall be effected in each case in the manner and to the extent specified in clause (vi) of this Section 2.09(b). (iii) Excess Cash Flow.

The Borrower shall notify the Administrative Agent by telephone (confirmed by telecopy) of any prepayment under this Section 2.09 (i) in the case of prepayment of a Eurodollar Borrowing, not later than 11:00 a.m., New York City time, three Business Days before the date of prepayment and (ii) in the case of a Base Rate Borrowing, not later than 11:00 a.m., New York City time, one Business Day before the date of prepayment. Each such notice shall be irrevocable and shall specify the prepayment date and the principal amount of each Borrowing or portion thereof to be prepaid; provided that, if a notice of prepayment is given in connection with a conditional notice of termination of the Commitments as contemplated by Section 2.07, then such notice of prepayment may be revoked if such notice of termination is revoked in accordance with Section 2.07. Promptly following receipt of any such notice related to a prepayment, the Administrative Agent shall advise the Lenders of the contents thereof. Each partial prepayment of a Borrowing shall be in an amount that would be permitted in the case of a Borrowing of the same Class and Type as provided in Section 2.02.

Accrued commitment fees shall be payable in arrears on each Quarterly Date and, in respect of any Commitments, on the date such Commitments terminate, commencing on the first such date to occur after the date hereof.

(b) The Loans comprising each Eurodollar Borrowing shall bear interest at a rate per annum equal to the Adjusted LIBO Rate for the Interest Period in effect for such Borrowing plus the Applicable Rate. (c) Notwithstanding the foregoing, if any principal of or interest on any Loan or any fee or other amount payable by the Borrower hereunder is not paid when due, whether at stated maturity, upon acceleration or otherwise, such overdue amount shall bear interest, after as well as before judgment, at a rate per annum equal to (i) in the case of overdue principal of any Loan, 2% plus the rate otherwise applicable to such Loan as provided above or (ii) in the case of any other amount, 2% plus the rate applicable to Base Rate Loans as provided above. (d) Accrued interest on each Loan shall be payable in arrears on each Interest Payment Date for such Loan; provided that (i) interest accrued pursuant to paragraph (c) of this Section 2.11 shall be payable on demand, (ii) in the event of any repayment or prepayment of any Loan (other than a prepayment of a Base Rate Revolving Credit Loan prior to the end of the Revolving Credit Availability Period), accrued interest on the principal amount repaid or prepaid shall be payable on the date of such repayment or prepayment, (iii) in the event of any conversion of any Eurodollar Loan prior to the end of the current Interest Period therefor, accrued interest on such Loan shall be payable on the effective date of such conversion and (iv) all accrued interest on Revolving Credit Loans shall be payable upon termination of the Revolving Credit Commitments.

The applicable Adjusted Base Rate, Adjusted LIBO Rate or LIBO Rate shall be determined by the Administrative Agent, and such determination shall be conclusive absent manifest error. Credit Agreement - 44 - SECTION 2.12. Alternate Rate of Interest. If prior to the commencement of any Interest Period for a Eurodollar Borrowing: (a) the Administrative Agent determines (which determination shall be conclusive absent manifest error) that adequate and reasonable means do not exist for ascertaining the Adjusted LIBO Rate or the LIBO Rate, as applicable, for such Interest Period; or (b) if such Borrowing is of a particular Class of Loans, the Administrative Agent is advised by the Required Revolving Credit Lenders or the Required Term Loan Lenders, as the case may be, that the Adjusted LIBO Rate or the LIBO Rate, as applicable, for such Interest Period will not adequately and fairly reflect the cost to such Lenders of making or maintaining their Loans of such Class included in such Borrowing for such Interest Period; then the Administrative Agent shall give notice thereof to the Borrower and the affected Lenders by telephone or telecopy as promptly as practicable thereafter and, until the Administrative Agent notifies the Borrower and such Lenders that the circumstances giving rise to such notice no longer exist, (i) any Interest Election Request that requests the conversion of any such Borrowing to, or continuation of any such Borrowing as, a Eurodollar Borrowing shall be ineffective and (ii) if any Borrowing Request requests a Eurodollar Borrowing, such Borrowing shall be made as a Base Rate Borrowing. SECTION 2.13. Increased Costs. (a) If any Change in Law shall: (i) impose, modify or deem applicable any reserve, special deposit or similar requirement against assets of, deposits with or for the account of, or credit extended by, any Lender (except any such reserve requirement reflected in the Adjusted LIBO Rate) or the LC Issuing Lender; or (ii) impose on any Lender or the LC Issuing Lender or the London interbank market any other condition affecting this Agreement or Eurodollar Loans made by such Lender or any Letter of Credit or participation therein; and the result of any of the foregoing shall be to increase the cost to such Lender of making or maintaining any Eurodollar Loan (or of maintaining its obligation to make any such Loan) or to increase the cost to such Lender or the LC Issuing Lender of participating in, issuing or maintaining any Letter of Credit or to reduce the amount of any sum received or receivable by such Lender or the LC Issuing Lender hereunder (whether of principal, interest or otherwise), then, upon delivery of the certificate provided for in Section 2.13(c), the Borrower will pay to such Lender or the LC Issuing Lender, as the case may be, such additional amount Credit Agreement - 45 - or amounts as will compensate such Lender or the LC Issuing Lender, as the case may be, for such additional costs incurred or reduction suffered. (b) If any Lender or the LC Issuing Lender reasonably determines that any Change in Law regarding capital requirements has or would have the effect of reducing the rate of return on such Lender's or the LC Issuing Lender's capital or on the capital of such Lender's or the LC Issuing Lender's holding company, if any, as a consequence of this Agreement or the Loans made by, or participations in Letters of Credit held by, such Lender, or the Letters of Credit issued by the LC Issuing Lender, to a level below that which such Lender or the LC Issuing Lender or such Lender's or the LC Issuing Lender's holding company could have achieved but for such Change in Law (taking into consideration such Lender's or the LC Issuing Lender's policies and the policies of such Lender's or the LC Issuing Lender's holding company with respect to capital adequacy), then from time to time the Borrower will pay to such Lender or the LC Issuing Lender, as the case may be, such additional amount or amounts as will compensate such Lender or the LC Issuing Lender, or such Lender's or the LC Issuing Lender's holding company, for any such reduction suffered. (c) A certificate of a Lender or the LC Issuing Lender setting forth the amount or amounts necessary to compensate such Lender or the LC Issuing Lender or its holding company, as the case may be, as specified in paragraph (a) or (b) of this Section 2.13 shall be delivered to the Borrower and shall be conclusive so long as it reflects a reasonable basis for the calculation of the amounts set forth therein and does not contain any manifest error. The Borrower shall pay such Lender or the LC Issuing Lender the amount shown as due on any such certificate within 10 days after receipt thereof. (d) Failure or delay on the part of any Lender or the LC Issuing Lender to demand compensation pursuant to this Section 2.13 shall not constitute a waiver of such Lender's or the LC Issuing Lender's right to demand such compensation; provided that the Borrower shall not be required to compensate a Lender or the LC Issuing Lender pursuant to this Section 2.13 for any increased costs or reductions incurred more than six months prior to the date that such Lender or the LC Issuing Lender, as the case may be, notifies the Borrower of the Change in Law giving rise to such increased costs or reductions and of such Lender's or the LC Issuing Lender's intention to claim compensation therefor; provided further that, if the Change in Law giving rise to such increased costs or reductions is retroactive, then the six-month period referred to above shall be extended to include the period of retroactive effect thereof. SECTION 2.14. Break Funding Payments. In the event of (a) the payment of any principal of any Eurodollar Loan other than on the last day of an Interest Period applicable thereto (including as a result of an Event of Default), (b) the conversion of any Eurodollar Loan other than on the last day of the Interest Period applicable thereto or (c) the failure to borrow, convert, continue or prepay any Loan on the date specified in any notice delivered pursuant hereto (regardless of whether such notice is permitted to be revocable and Credit Agreement - 46 - is revoked in accordance herewith), then, in any such event, the Borrower shall compensate each Lender for the loss, cost and expense attributable to such event. In the case of a Eurodollar Loan, the loss to any Lender attributable to any such event shall be deemed to include an amount determined by such Lender to be equal to the excess, if any, of (i) the amount of interest that such Lender would pay for a deposit equal to the principal amount of such Loan for the period (the "Breakage Period") from the date of such payment, conversion, failure or assignment to the last day of the then current Interest Period for such Loan (or, in the case of a failure to borrow, convert or continue, the duration of the Interest Period that would have resulted from such borrowing, conversion or continuation) if the interest rate payable on such deposit were equal to the Adjusted LIBO Rate for such Interest Period, over (ii) the amount of interest that such Lender would earn on such principal amount for the Breakage Period if such Lender were to invest such principal amount for the Breakage Period at the interest rate that would be bid by such Lender (or an affiliate of such Lender) for U.S. dollar deposits from other banks in the eurodollar market at the commencement of the Breakage Period. A certificate of any Lender setting forth any amount or amounts that such Lender is entitled to receive pursuant to this Section 2.14 shall be delivered to the Borrower and shall be conclusive absent manifest error. The Borrower shall pay such Lender the amount shown as due on any such certificate within 10 days after receipt thereof. SECTION 2.15. Taxes. (a) Any and all payments by or on account of any obligation of the Borrower hereunder shall be made free and clear of and without deduction for any Indemnified Taxes or Other Taxes; provided that if the Borrower shall be required to deduct any Indemnified Taxes or Other Taxes from such payments, then (i) the sum payable shall be increased as necessary so that after making all required deductions (including deductions applicable to additional sums payable under this Section 2.15) the Administrative Agent, Lender or the LC Issuing Lender (as the case may be) receives an amount equal to the sum it would have received had no such deductions been made, (ii) the Borrower shall make such deductions and (iii) the Borrower shall pay the full amount deducted to the relevant Governmental Authority in accordance with applicable law. (b) In addition the Borrower shall pay any Other Taxes to the relevant Governmental Authority in accordance with applicable law. Credit Agreement - 47 - (c) The Borrower shall indemnify the Administrative Agent, each Lender and the LC Issuing Lender, within 10 days after written demand therefor, for the full amount of any Indemnified Taxes or Other Taxes (including Indemnified Taxes or Other Taxes imposed or asserted on or attributable to amounts payable under this Section 2.15) paid by the Administrative Agent, such Lender or the LC Issuing Lender, as the case may be, and any penalties, interest and reasonable expenses arising therefrom or with respect thereto, whether or not such Indemnified Taxes or Other Taxes were correctly or legally imposed or asserted by the relevant Governmental Authority. A certificate as to the amount of such payment or liability delivered to the Borrower by a Lender or the LC Issuing Lender, or by the Administrative Agent on its own behalf or on behalf of a Lender or the LC Issuing Lender, shall be conclusive absent manifest error. (d) As soon as practicable after any payment of Indemnified Taxes or Other Taxes by the Borrower to a Governmental Authority, the Borrower shall deliver to the Administrative Agent the original or a certified copy of a receipt issued by such Governmental Authority evidencing such payment, a copy of the return reporting such payment or other evidence of such payment reasonably satisfactory to the Administrative Agent. (e) Any Foreign Lender that is entitled at any time under then current law to an exemption from or reduction of withholding tax under the law of the jurisdiction in which the Borrower is located, or any treaty to which such jurisdiction is a party, with respect to payments under this Agreement shall deliver to the Borrower (with a copy to the Administrative Agent), on or before Effective Date or such later date on which such Person becomes a Foreign Lender and at the time or times prescribed by applicable law or reasonably requested by the Borrower, such properly completed and executed documentation prescribed by applicable law as will permit such payments to be made without withholding or at a reduced rate. SECTION 2.16. Payments Generally; Pro Rata Treatment; Sharing of Set-Offs. (a) The Borrower shall make each payment required to be made by it hereunder (whether of principal, interest, fees or reimbursement of LC Disbursements, or under Section 2.13, 2.14 or 2.15, or otherwise) prior to 12:00 noon, New York City time, on the date when due, in immediately available funds, without set-off or counterclaim. Any amounts received after such time on any date may, in the discretion of the Administrative Agent, be deemed to have been received on the next succeeding Business Day for purposes of calculating interest thereon. All such payments shall be made to the Administrative Agent at such of its offices in New York City as shall be notified to the relevant parties from time to time, except payments to be made directly to the LC Issuing Lender as expressly provided herein and except that payments pursuant to Sections 2.13, 2.14, 2.15, 3.03 and 10.03 shall be made directly to the Persons entitled thereto. The Administrative Agent shall distribute any such payments received by it for the account of any other Person to the appropriate recipient promptly following receipt thereof. If any payment hereunder shall be due on a day that is Credit Agreement - 48 - not a Business Day, the date for payment shall be extended to the next succeeding Business Day, and, in the case of any payment accruing interest, interest thereon shall be payable for the period of such extension. All payments hereunder shall be made in U.S. dollars. (b) If at any time insufficient funds are received by and available to the Administrative Agent to pay fully all amounts of principal, unreimbursed LC Disbursements, interest and fees then due hereunder, such funds shall be applied (i) first, to pay interest and fees then due hereunder, ratably among the parties entitled thereto in accordance with the amounts of interest and fees then due to such parties, and (ii) second, to pay principal and unreimbursed LC Disbursements then due hereunder, ratably among the parties entitled thereto in accordance with the amounts of principal and unreimbursed LC Disbursements then due to such parties. (c) Except to the extent otherwise provided herein: (i) each borrowing of Loans of a particular Class from the Lenders under Section 2.01 shall be made from the relevant Lenders, each payment of commitment fee under Section 2.10 in respect of Commitments of a particular Class shall be made for account of the relevant Lenders, and each termination or reduction of the amount of the Commitments of a particular Class under Section 2.03 shall be applied to the respective Commitments of such Class of the relevant Lenders, pro rata according to the amounts of their respective Commitments of such Class; (ii) Eurodollar Loans of any Class having the same Interest Period shall be allocated pro rata among the relevant Lenders according to the amounts of their Commitments of such Class (in the case of the making of Loans) or their respective Loans of such Class (in the case of conversions and continuations of Loans); (iii) each payment or prepayment by the Borrower of principal of Loans of a particular Class shall be made for account of the relevant Lenders pro rata in accordance with the respective unpaid principal amounts of the Loans of such Class held by them; (iv) each payment by the Borrower of interest on Loans of a particular Class shall be made for account of the relevant Lenders pro rata in accordance with the amounts of interest on such Loans then due and payable to the respective Lenders; and (v) each payment by the Borrower of participation fees in respect of Letters of Credit shall be made for the account of the Revolving Credit Lenders pro rata in accordance with the amount of participation fees then due and payable to the Revolving Credit Lenders. (d) If any Lender shall, by exercising any right of set-off or counterclaim or otherwise, obtain payment in respect of any principal of or interest on any of its Loans (or participations in LC Disbursements) of any Class resulting in such Lender receiving payment of a greater proportion of the aggregate principal amount of its Loans (and participations in LC Disbursements) of such Class and accrued interest thereon than the proportion of such amounts received by any other Lender of any other Class, then the Lender receiving such greater proportion shall purchase (for cash at face value) participations in the Loans (and LC Disbursements) of the other Lenders to the extent necessary so that the benefit of such payments shall be shared by all the Lenders ratably in accordance with the aggregate amount of principal of and accrued interest on their respective Loans (and participations in LC Disbursements); provided that (i) if any such participations are purchased and all or any Credit Agreement - 49 - portion of the payment giving rise thereto is recovered, such participations shall be rescinded and the purchase price restored to the extent of such recovery, without interest, and (ii) the provisions of this paragraph shall not be construed to apply to any payment obtained by a Lender as consideration for the assignment of or sale of a participation in any of its Loans (or participations in LC Disbursements) to any assignee or participant, other than to any Credit Party or any subsidiary or Affiliate thereof (as to which the provisions of this paragraph shall apply). The Borrower consents to the foregoing and agrees, to the extent it may effectively do so under applicable law, that any Lender acquiring a participation pursuant to the foregoing arrangements may exercise against the Borrower rights of set-off and counterclaim with respect to such participation as fully as if such Lender were a direct creditor of the Borrower in the amount of such participation. (e) Unless the Administrative Agent shall have received notice from the Borrower prior to the date on which any payment is due to the Administrative Agent for the account of the Lenders or the LC Issuing Lender entitled thereto (the "Applicable Recipient") hereunder that the Borrower will not make such payment, the Administrative Agent may assume that the Borrower has made such payment on such date in accordance herewith and may, in reliance upon such assumption, distribute to the Applicable Recipient the amount due. In such event, if the Borrower has not in fact made such payment, then each Applicable Recipient severally agrees to repay to the Administrative Agent forthwith on demand the amount so distributed to such Applicable Recipient with interest thereon, for each day from and including the date such amount is distributed to it to but excluding the date of payment to the Administrative Agent, at the Federal Funds Effective Rate. (f) If any Lender shall fail to make any payment required to be made by it pursuant to Section 2.04(d), 2.04(e), 2.05(b) or 2.16(e), then the Administrative Agent may, in its discretion (notwithstanding any contrary provision hereof), apply any amounts thereafter received by the Administrative Agent for the account of such Lender to satisfy such Lender's obligations under such Section until all such unsatisfied obligations are fully paid. (g) Anything in this Agreement to the contrary notwithstanding, each Lender hereby agrees with each other Lender that no Lender shall take any action to protect or enforce its rights arising out of this Agreement or any promissory notes prepared pursuant to Section 2.09(f) (including, without limitation, exercising any rights of setoff) without first obtaining the prior written consent of the Administrative Agent or the Required Lenders, it being the intent of the Lenders that any such action to protect or enforce rights under this Agreement and any promissory notes prepared pursuant to Section 2.09(f) shall be taken in concert and at the direction or with the consent of the Administrative Agent or the Required Lenders and not individually by a single Lender. SECTION 2.17. Mitigation Obligations. Upon the earliest to occur of (i) notice or knowledge by Lender of any event that could result in or provide a basis for a request for compensation under Section 2.13 and a determination by such Lender that it will request such compensation, (ii) a request by Lender for compensation under Section 2.13, or Credit Agreement - 50 - (iii) the Borrower being required to pay any additional amount to any Lender or any Governmental Authority for the account of any Lender pursuant to Section 2.15, then such Lender shall use reasonable efforts to designate a different lending office for funding or booking its Loans hereunder or to assign its rights and obligations, hereunder to another of its offices, branches or affiliates, if, in the judgment of such Lender, such designation or assignment (i) would eliminate or reduce amounts payable pursuant to Section 2.13 or 2.15, as the case may be, in the future and (ii) would not subject such Lender to any unreimbursed cost or expense and would not otherwise be disadvantageous to such Lender; provided that such Lender shall not be required to make any such designation or assignment unless the Borrower agrees to pay all reasonable out-of-pocket costs and expenses incurred by any Lender in connection therewith. ARTICLE III Guarantee by Subsidiary Guarantors SECTION 3.01. The Guarantee. The Subsidiary Guarantors hereby jointly and severally guarantee to each Lender, the LC Issuing Lender and the Administrative Agent and their respective successors and assigns the prompt payment in full when due (whether at stated maturity, by acceleration or otherwise) of the principal of and interest on the Loans made by the Lenders to the Borrower, all LC Disbursements and all other amounts from time to time owing to the Lenders, the LC Issuing Lender or the Administrative Agent by the Borrower hereunder or under any other Loan Document, and all obligations of the Borrower to any Lender under any Hedging Agreement, in each case strictly in accordance with the terms thereof and including any interest accruing after the commencement of any proceeding referred to in Article VIII (h) or (i), whether or not allowed as a claim in such proceeding (such obligations being herein collectively called the "Guaranteed Obligations"). The Subsidiary Guarantors hereby further jointly and severally agree that if the Borrower shall fail to pay in full when due (whether at stated maturity, by acceleration or otherwise) any of the Guaranteed Obligations, the Subsidiary Guarantors will promptly pay the same, without any demand or notice whatsoever, and that in the case of any extension of time of payment or renewal of any of the Guaranteed Obligations, the same will be promptly paid in full when due (whether at extended maturity, by acceleration or otherwise) in accordance with the terms of such extension or renewal. SECTION 3.02. Obligations Unconditional. The obligations of the Subsidiary Guarantors under Section 3.01 are absolute and unconditional, joint and several, irrespective of the value, genuineness, validity, regularity or enforceability of this Agreement, the other Loan Documents or any other agreement or instrument referred to herein or therein, or any substitution, release or exchange of any other guarantee of or security for any of the Guaranteed Obligations, and, to the fullest extent permitted by applicable law, irrespective of any other circumstance whatsoever that might otherwise constitute a legal or equitable Credit Agreement - 51 - discharge or defense of a surety or guarantor, it being the intent of this Section 3.02 that the obligations of the Subsidiary Guarantors hereunder shall be absolute and unconditional, joint and several, under any and all circumstances. Without limiting the generality of the foregoing, it is agreed that the occurrence of any one or more of the following shall not alter or impair the liability of the Subsidiary Guarantors hereunder which shall remain absolute and unconditional as described above: (a) at any time or from time to time, without notice to the Subsidiary Guarantors, the time for any performance of or compliance with any of the Guaranteed Obligations shall be extended, or such performance or compliance shall be waived; (b) any of the acts mentioned in any of the provisions hereof or of the other Loan Documents or any other agreement or instrument referred to herein or therein shall be done or omitted; (c) the maturity of any of the Guaranteed Obligations shall be accelerated, or any of the Guaranteed Obligations shall be modified, supplemented or amended in any respect, or any right hereunder or under the other Loan Documents or any other agreement or instrument referred to herein or therein shall be waived or any other guarantee of any of the Guaranteed Obligations or any security therefor shall be released or exchanged in whole or in part or otherwise dealt with; or (d) any lien or security interest granted to, or in favor of, the Administrative Agent, the LC Issuing Lender or any Lender or Lenders as security for any of the Guaranteed Obligations shall fail to be perfected. The Subsidiary Guarantors hereby expressly waive diligence, presentment, demand of payment, protest and all notices whatsoever, and any requirement that the Administrative Agent, the LC Issuing Lender or any Lender exhaust any right, power or remedy or proceed against the Borrower hereunder or under the other Loan Documents or any other agreement or instrument referred to herein or therein, or against any other Person under any other guarantee of, or security for, any of the Guaranteed Obligations. SECTION 3.03. Reinstatement. The obligations of the Subsidiary Guarantors under this Article III shall be automatically reinstated if and to the extent that for any reason any payment by or on behalf of the Borrower in respect of the Guaranteed Obligations is rescinded or must be otherwise restored by any holder of any of the Guaranteed Obligations, whether as a result of any proceedings in bankruptcy or reorganization or otherwise, and the Subsidiary Guarantors jointly and severally agree that they will indemnify the Administrative Agent, the LC Issuing Lender and each Lender on demand for all reasonable costs and expenses (including fees of counsel) incurred by the Administrative Agent, any Lender or the LC Issuing Lender in connection with such rescission or restoration, including any such costs and expenses incurred in defending against any claim alleging that such payment constituted a Credit Agreement - 52 - preference, fraudulent transfer or similar payment under any bankruptcy, insolvency or similar law. SECTION 3.04. Subrogation. Each Subsidiary Guarantor hereby waives all rights of subrogation or contribution, whether arising by contract or operation of law (including any such right arising under the Federal Bankruptcy Code of 1978, as amended) or otherwise by reason of any payment by it pursuant to the provisions of this Article III and further agrees, to the extent valid under applicable law, with the Borrower for the benefit of each of its creditors (including the LC Issuing Lender, each Lender and the Administrative Agent) that any such payment by it shall constitute a dividend by such Subsidiary Guarantor to the Borrower. SECTION 3.05. Remedies. The Subsidiary Guarantors jointly and severally agree that, as between the Subsidiary Guarantors on the one hand and the Administrative Agent, the Lenders and the LC Issuing Lender on the other hand, the obligations of the Borrower hereunder may be declared to be forthwith due and payable as provided in Article VIII or Section 2.04(i), as applicable (and shall be deemed to have become automatically due and payable in the circumstances provided in Article VIII or Section 2.04(i), as applicable) for purposes of Section 3.01 notwithstanding any stay, injunction or other prohibition preventing such declaration (or such obligations from becoming automatically due and payable) as against the Borrower and that, in the event of such declaration (or such obligations being deemed to have become automatically due and payable), such obligations (whether or not due and payable by the Borrower) shall forthwith become due and payable by the Subsidiary Guarantors for purposes of Section 3.01. SECTION 3.06. Instrument for the Payment of Money. Each Subsidiary Guarantor hereby acknowledges that the guarantee in this Article III constitutes an instrument for the payment of money, and consents and agrees that the LC Issuing Lender, any Lender or the Administrative Agent, at its sole option, in the event of a dispute by the Subsidiary Guarantors in the payment of any moneys due hereunder, shall have the right to bring a motion-action under New York CPLR Section 3213. SECTION 3.07. Continuing Guarantee. The guarantee in this Article III is a continuing guarantee, and shall apply to all Guaranteed Obligations whenever arising. SECTION 3.08. Rights of Contribution. The Subsidiary Guarantors hereby agree, as between themselves, that if any Subsidiary Guarantor shall become an Excess Funding Guarantor (as defined below) by reason of the payment by such Subsidiary Guarantor of any Guaranteed Obligations, each other Subsidiary Guarantor shall, on demand of such Excess Funding Guarantor (but subject to the next sentence), pay to such Excess Funding Guarantor an amount equal to such Subsidiary Guarantor's Pro Rata Share (as defined below and determined, for this purpose, without reference to the properties, debts and liabilities of such Excess Funding Guarantor) of the Excess Payment (as defined below) in respect of such Credit Agreement - 53 - Guaranteed Obligations. The payment obligation of a Subsidiary Guarantor to any Excess Funding Guarantor under this Section 3.08 shall be subordinate and subject in right of payment to the prior payment in full of the obligations of such Subsidiary Guarantor under the other provisions of this Article III and such Excess Funding Guarantor shall not exercise any right or remedy with respect to such excess until payment and satisfaction in full of all of such obligations. For purposes of this Section 3.08, (a) "Excess Funding Guarantor" means, in respect of any Guaranteed Obligations, a Subsidiary Guarantor that has paid an amount in excess of its Pro Rata Share of such Guaranteed Obligations, (b) "Excess Payment" means, in respect of any Guaranteed Obligations, the amount paid by an Excess Funding Guarantor in excess of its Pro Rata Share of such Guaranteed Obligations and (c) "Pro Rata Share" means, for any Subsidiary Guarantor, the ratio (expressed as a percentage) of (i) the amount by which the aggregate fair saleable value of all properties of such Subsidiary Guarantor (excluding any shares of stock of, or ownership interest in, any other Subsidiary Guarantor) exceeds the amount of all the debts and liabilities of such Subsidiary Guarantor (including contingent, subordinated, unmatured and unliquidated liabilities, but excluding the obligations of such Subsidiary Guarantor hereunder and any obligations of any other Subsidiary Guarantor that have been Guaranteed by such Subsidiary Guarantor) to (ii) the amount by which the aggregate fair saleable value of all properties of all of the Credit Parties exceeds the amount of all the debts and liabilities (including contingent, subordinated, unmatured and unliquidated liabilities, but excluding the obligations of the Borrower and the Subsidiary Guarantors hereunder and under the other Loan Documents) of all of the Credit Parties, determined (x) with respect to any Subsidiary Guarantor that is a party hereto on the Effective Date, as of the Effective Date, and (y) with respect to any other Subsidiary Guarantor, as of the date such Subsidiary Guarantor becomes a Subsidiary Guarantor hereunder. SECTION 3.09. General Limitation on Guarantee Obligations. In any action or proceeding involving any state corporate law, or any state or Federal bankruptcy, insolvency, reorganization or other law affecting the rights of creditors generally, if the obligations of any Subsidiary Guarantor under Section 3.01 would otherwise, taking into account the provisions of Section 3.08, be held or determined to be void, invalid or unenforceable, or subordinated to the claims of any other creditors, on account of the amount of its liability under Section 3.01, then, notwithstanding any other provision hereof to the contrary, the amount of such liability shall, without any further action by such Subsidiary Guarantor, any Lender, the Administrative Agent or any other Person, be automatically limited and reduced to the highest amount that is valid and enforceable and not subordinated to the claims of other creditors as determined in such action or proceeding.

Without limiting the generality of the foregoing, in the event that the Borrower shall form or acquire any new Domestic Subsidiary after the date hereof which the Borrower or such Subsidiary anticipates will not be an Inactive Subsidiary (or in the event that any theretofore Inactive Subsidiary that is a Domestic Subsidiary shall cease to be an Inactive Subsidiary), the Borrower will, and will cause each of its Subsidiaries to, cause such new Domestic Subsidiary (or such theretofore Inactive Subsidiary) within ten Business Days of such formation or acquisition notify the Administrative Agent of such formation or acquisition and promptly take all such actions as the Administrative Agent may request to cause such Subsidiary to become a "Subsidiary Guarantor" (and thereby, a "Credit Party") hereunder and under the Security Agreement pursuant to a written instrument in form and substance reasonably satisfactory to the Administrative Agent, to become a party to the Security Agreement and to deliver such proof of corporate action, incumbency of officers, opinions of counsel and other documents (including Uniform Commercial Code Financing Statements) as are consistent with those delivered by Credit Party pursuant to Section 5.01 or as the Required Lenders or the Administrative Agent shall have requested.

Chase shall have the same rights and powers in its capacity as a Lender hereunder as any other Lender and may exercise the same as though Chase were not the Administrative Agent, and Chase and its Affiliates may accept deposits from, lend money to and generally engage in any kind of business with any Credit Party or any Subsidiary or other Affiliate of any thereof as if it were not the Administrative Agent hereunder. The Administrative Agent shall not have any duties or obligations except those expressly set forth in this Agreement and the other Loan Documents. Without limiting the Credit Agreement - 87 - generality of the foregoing, (a) the Administrative Agent shall not be subject to any fiduciary or other implied duties, regardless of whether a Default has occurred and is continuing, (b) the Administrative Agent shall not have any duty to take any discretionary action or exercise any discretionary powers, except discretionary rights and powers expressly contemplated by this Agreement and the other Loan Documents that the Administrative Agent is required to exercise in writing by the Required Lenders, and (c) except as expressly set forth herein and in the other Loan Documents, the Administrative Agent shall not have any duty to disclose, and shall not be liable for the failure to disclose, any information relating to any Credit Party, NL or any of their respective Subsidiaries that is communicated to or obtained by Chase or any of its Affiliates in any capacity. The Administrative Agent shall not be liable for any action taken or not taken by it with the consent or at the request of the Required Lenders or, if provided herein, with the consent or at the request of the Required Revolving Credit or the Required Term Loan Lenders, or in the absence of its own gross negligence or wilful misconduct. The Administrative Agent shall not be deemed to have knowledge of any Default unless and until written notice thereof is given to the Administrative Agent by the Borrower or a Lender (whereupon the Administrative Agent shall promptly deliver a copy thereof to the Lenders), and the Administrative Agent shall not be responsible for or have any duty to ascertain or inquire into (i) any statement, warranty or representation made in or in connection with this Agreement or the other Loan Documents, (ii) the contents of any certificate, report or other document delivered hereunder or under any of the other Loan Documents or in connection herewith of therewith, (iii) the performance or observance of any of the covenants, agreements or other terms or conditions set forth herein or in any other Loan Document, (iv) the validity, enforceability, effectiveness or genuineness of this Agreement, the other Loan Documents or any other agreement, instrument or document, or (v) the satisfaction of any condition set forth in Article V or elsewhere herein, other than to confirm receipt of items expressly required to be delivered to the Administrative Agent. The Administrative Agent shall not, except to the extent expressly instructed by the Required Lenders with respect to collateral security under the Security Documents, be required to initiate or conduct any litigation or collection proceedings hereunder or under any other Loan Document. The Administrative Agent shall be entitled to rely upon, and shall not incur any liability for relying upon, any notice, request, certificate, consent, statement, instrument, document or other writing believed by it to be genuine and to have been signed or sent by the proper Person. The Administrative Agent also may rely upon any statement made to it orally or by telephone and believed by it to be made by the proper Person, and shall not incur any liability for relying thereon. The Administrative Agent may consult with legal counsel (who may be counsel for the Borrower), independent accountants and other experts selected by it, and shall not be liable for any action taken or not taken by it in accordance with the advice of any such counsel, accountants or experts. Credit Agreement - 88 - The Administrative Agent may perform any and all of its duties, and exercise its rights and powers, by or through any one or more sub-agents appointed by the Administrative Agent. The Administrative Agent and any such sub-agent may perform any and all its duties and exercise its rights and powers through its Related Parties. The exculpatory provisions of the preceding paragraphs shall apply to any such sub-agent and to the Related Parties of the Administrative Agent and any such sub-agent, and shall apply to its activities in connection with the syndication of the credit facilities provided for herein as well as activities as the Administrative Agent. Subject to the appointment and acceptance of a successor Administrative Agent, as provided in this paragraph, the Administrative Agent may resign at any time by notifying the Lenders, the LC Issuing Lender and the Borrower. Upon any such resignation, the Required Lenders shall have the right, in consultation with the Borrower, to appoint a successor Administrative Agent. If no successor shall have been so appointed and shall have accepted such appointment within 30 days after such retiring Administrative Agent gives notice of its resignation, then such retiring Administrative Agent may, on behalf of the Lenders and the LC Issuing Lender, appoint a successor Administrative Agent, which shall be a bank with an office in New York, New York, or an Affiliate of any such bank. Upon the acceptance of its appointment as Administrative Agent, by a successor, such successor shall succeed to and become vested with all the rights, powers, privileges and duties of the retiring Administrative Agent, and the retiring Administrative Agent shall be discharged from its duties and obligations hereunder and under the other Loan Documents. The fees payable by the Borrower to a successor Administrative Agent shall be the same as those payable to its predecessor unless otherwise agreed between the Borrower and such successor. After an Administrative Agent's resignation hereunder, the provisions of this Article IX and Sections 3.03 and 10.03 shall continue in effect for its benefit in respect of any actions taken or omitted to be taken by it while it was acting as Administrative Agent. Each Lender acknowledges that it has, independently and without reliance upon the Administrative Agent, the LC Issuing Lender or any other Lender and based on such documents and information as it has deemed appropriate, made its own credit analysis and decision to enter into this Agreement. Each Lender also acknowledges that it will, independently and without reliance upon the Administrative Agent, the LC Issuing Lender or any other Lender and based on such documents and information as it shall from time to time deem appropriate, continue to make its own decisions in taking or not taking action under or based upon this Agreement and the other Loan Documents, any related agreement or any document furnished hereunder or thereunder. The Documentation Agent identified on the cover page of this Agreement shall have no duties or responsibilities hereunder other than as a Lender hereunder. Credit Agreement - 89 - ARTICLE X Miscellaneous SECTION 10.01. Notices. Except in the case of notices and other communications expressly permitted to be given by telephone, all notices and other communications provided for herein shall be in writing and shall be delivered by hand or overnight courier service, mailed by certified or registered mail or sent by telecopy, as follows: (a) if to the Borrower, (i) to Rheox, Inc. c/o NL Industries, Inc. at 70 East 55th Street, New York, New York 10022, Attention of Susan E.

All notices and other communications given to any party hereto in accordance with the provisions of this Agreement shall be deemed to have been given on the date of receipt. SECTION 10.02. Waivers; Amendments. (a) No failure or delay by the Administrative Agent, the LC Issuing Lender or any Lender in exercising any right or power hereunder shall operate as a waiver thereof, nor shall any single or partial exercise of any such right or power, or any abandonment or discontinuance of steps to enforce such a right or power, preclude any other or further exercise thereof or the exercise of any other right or power. The rights and remedies of the Administrative Agent, the LC Issuing Lender and the Lenders hereunder are cumulative and are not exclusive of any rights or remedies that they would otherwise have. No waiver of any provision of this Agreement or consent to any departure by any Credit Party therefrom shall in any event be effective unless the same shall be permitted by paragraph (b) of this Section 10.02, and then such waiver or consent shall be effective only in the specific instance and for the purpose for which given. Without limiting the generality of the foregoing, the making of Credit Agreement - 90 - a Loan or issuance of a Letter of Credit shall not be construed as a waiver of any Default, regardless of whether the Administrative Agent, any Lender or the LC Issuing Lender may have had notice or knowledge of such Default at the time. (b) Neither this Agreement nor any provision hereof may be waived, amended or modified except pursuant to an agreement or agreements in writing entered into by the Borrower and the Required Lenders or by the Borrower and the Administrative Agent with the consent of the Required Lenders; provided that no such agreement shall: (i) increase the Commitment of any Lender without the written consent of such Lender; (ii) reduce the principal amount of any Loan or LC Disbursement or reduce the rate of interest thereon, or reduce any fees payable hereunder, without the written consent of each Lender affected thereby; (iii) postpone the scheduled date of payment of the principal amount of any Loan or LC Disbursement, or any interest thereon, or any fees payable hereunder, or reduce the amount of, waive or excuse any such payment, or postpone the scheduled date of expiration of any Commitment, without the written consent of each Lender affected thereby; (iv) change Section 2.09 in a manner that would reduce or alter the application of prepayments thereunder, or change Section 2.16(b), (c) or (d) in a manner that would alter the pro rata sharing of payments required thereby, without in each case the written consent of each Lender; (v) alter the rights or obligations of the Borrower to prepay Loans without the written consent of each Lender; (vi) change any of the provisions of this Section 10.02 or the definition of "Required Lenders", "Required Revolving Credit Lenders", or "Required Term Loan Lenders", or any other provision hereof specifying the number or percentage of Lenders required to waive, amend or modify any rights hereunder or under any other Loan Document or make any determination or grant any consent hereunder or thereunder, without the written consent of each Lender; or (vii) release all or substantially all of the Subsidiary Guarantors from their obligations in respect of their Guarantee under Article III, without the written consent of each Lender; Credit Agreement - 91 - provided further that no such agreement shall amend, modify or otherwise affect the rights or duties of the Administrative Agent or the LC Issuing Lender hereunder without the prior written consent of the Administrative Agent or the LC Issuing Lender, as the case may be. Anything in this Agreement to the contrary notwithstanding, no waiver or modification of any provision of this Agreement that has the effect (either immediately or at some later time) of enabling the Borrower to satisfy a condition precedent to the making of Revolving Credit Loans or Term Loans shall be effective against the Revolving Credit Lenders or Term Loan Lenders, respectively, unless the Required Revolving Credit Lenders or Required Term Loan Lenders, respectively, shall have concurred with such waiver or modification. (c) Neither any Security Document nor any provision thereof may be waived, amended or modified except pursuant to an agreement or agreements in writing entered into by the Credit Parties party thereto, and by the Administrative Agent with the consent of the Required Lenders, provided that, without the prior consent of each Lender, the Administrative Agent shall not (except as provided herein or in the applicable Security Document) release all or substantially all of the collateral thereunder or otherwise terminate any Lien under any Security Document, agree to additional obligations being secured by such collateral (unless the Lien for such additional obligations shall be junior to the Lien in favor of the other obligations secured by such Security Document, in which event the Administrative Agent may consent to such junior Lien provided that it obtains the consent of the Required Lenders thereto), alter the relative priorities of the obligations entitled to the benefits of the Liens created under such Security Document, except that no such consent shall be required, and the Administrative Agent is hereby authorized, to release any Lien covering property that is the subject of either a Disposition of property permitted hereunder or a Disposition to which the Required Lenders have consented. SECTION 10.03. Expenses; Indemnity; Damage Waiver. (a) The Credit Parties jointly and severally agree to pay, or reimburse the Administrative Agent or Lenders for paying, (i) all reasonable out-of-pocket expenses incurred by the Administrative Agent and its Affiliates, including the reasonable fees, charges and disbursements of Special Counsel, in connection with the syndication of the credit facilities provided for herein, the preparation of this Agreement and the other Loan Documents (and any Uniform Commercial Code financing statements required by any Security Document to be filed with respect to the security interests in personal property and fixtures created pursuant thereto) or any amendments, modifications or waivers of the provisions hereof or thereof (whether or not the transactions contemplated hereby or thereby shall be consummated), (ii) all out-of-pocket expenses incurred by the LC Issuing Lender in connection with the issuance, amendment, renewal or extension of any Letter of Credit or any demand for payment thereunder, (iii) all out-of-pocket expenses incurred by the Administrative Agent, the LC Issuing Lender or any Lender, including the fees, charges and disbursements of any Credit Agreement - 92 - counsel for such Administrative Agent, LC Issuing Lender or Lender, in connection with the enforcement or protection of its rights in connection with this Agreement and the other Loan Documents, including its rights under this Section 10.03, or in connection with the Loans made or Letters of Credit issued hereunder, including in connection with any workout, restructuring or negotiations in respect thereof, and (iv) all transfer, stamp, documentary or other similar taxes, assessments or charges levied by any governmental or revenue authority in respect of this Agreement or any of the other Loan Documents or any other document referred to herein or therein and all costs, expenses, taxes, assessments and other charges incurred in connection with any filing, registration, recording or perfection of any security interest contemplated by any Security Document, by any Uniform Commercial Code financing statements required by any Security Document to be filed with respect to the security interests in personal property and fixtures created pursuant thereto, or by any other document referred to therein. Notwithstanding anything to the contrary in this Section 10.03(a), the Borrower shall not be obligated to pay the fees and expenses of more than one law firm representing the Administrative Agent and the Lenders (which law firm shall be selected by the Administrative Agent, or if the Required Lenders so decide, by the Required Lenders) unless (x) the Administrative Agent or the Required Lenders reasonably determine that the retention of more than one law firm is advisable because questions arise under laws of jurisdictions in which the principal law firm engaged is not authorized to practice law or (y) in the case of the foregoing clause (iii), the Administrative Agent or any Lender or Lenders have different or conflicting interests. (b) The Credit Parties jointly and severally agree to indemnify the Administrative Agent, the LC Issuing Lender and each Lender, and each Related Party of any of the foregoing Persons (each such Person being called an "Indemnitee") against, and hold each Indemnitee harmless from, any and all losses, claims, damages, liabilities and related expenses, including the fees, charges and disbursements of any counsel for any Indemnitee, incurred by or asserted against any Indemnitee arising out of, in connection with, or as a result of (i) the execution or delivery of this Agreement, the other Loan Documents or any agreement or instrument contemplated hereby, the performance by the parties hereto and thereto of their respective obligations hereunder or thereunder or the consummation of the Transactions or any other transactions contemplated hereby or thereby, (ii) any Loan or Letter of Credit or the use of the proceeds therefrom (including any refusal by the LC Issuing Lender to honor a demand for payment under a Letter of Credit if the documents presented in connection with such demand do not strictly comply with the terms of such Letter of Credit), (iii) any actual or alleged presence, Release or threatened Release of Hazardous Materials related to any property owned or operated by any Credit Party or any of their Subsidiaries, or any Environmental Liability related in any way to any Credit Party or any of their Subsidiaries, or (iv) any actual or prospective claim, litigation, investigation or proceeding relating to any of the foregoing, whether based on contract, tort or any other theory and regardless of whether any Indemnitee is a party thereto; provided that such indemnity shall not, as to any Indemnitee, be available to the extent that such losses, claims, damages, liabilities or related expenses (are determined by a court of competent jurisdiction by final and Credit Agreement - 93 - nonappealable judgment to have) resulted from the gross negligence or wilful misconduct of such Indemnitee. Notwithstanding anything to the contrary in this Section 10.03(b), the Borrower shall not be obligated to pay or otherwise indemnify the Administrative Agent or any Lender for the fees and expenses of more than one law firm representing the Administrative Agent and the Lenders (which law firm shall be selected by the Administrative Agent, or if the Required Lenders so decide, by the Required Lenders) unless (x) the Administrative Agent or the Required Lenders reasonably determine that the retention of more than one law firm is advisable because questions arise under laws of jurisdictions in which the principal law firm engaged is not authorized to practice law or (y) the Administrative Agent or any Lender or Lenders have different or conflicting interests. (c) To the extent that the Credit Parties fail to pay any amount required to be paid by them to the Administrative Agent under paragraph (a) or (b) of this Section 10.03, each Lender severally agrees to pay to the Administrative Agent such Lender's Applicable Percentage (determined as of the time that the applicable unreimbursed expense or indemnity payment is sought) of such unpaid amount; provided that the unreimbursed expense or indemnified loss, claim, damage, liability or related expense, as the case may be, was incurred by or asserted against the Administrative Agent in its capacity as such. To the extent that the Credit Parties fail to pay any amount required to be paid by them to the LC Issuing Lender under paragraph (a) or (b) of this Section 10.03, each Revolving Credit Lender severally agrees to pay to the LC Issuing Lender such Lender's Applicable Percentage (determined as of the time that the applicable unreimbursed expense or indemnity payment is sought) of such unpaid amount; provided that the unreimbursed expense or indemnified loss, claim, damage, liability or related expense, as the case may be, was incurred by or asserted against the Administrative Agent in its capacity as such. (d) To the extent permitted by applicable law, none of the Credit Parties shall assert, and each Credit Party hereby waives, any claim against any Indemnitee, on any theory of liability, for special, indirect, consequential or punitive damages (as opposed to direct or actual damages) arising out of, in connection with, or as a result of, this Agreement, the other Loan Documents or any agreement or instrument contemplated hereby or thereby, the Transactions, any Loan or Letter of Credit or the use of the proceeds thereof. (e) All amounts due under this Section 10.03 shall be payable promptly after written demand therefor. SECTION 10.04. Successors and Assigns. (a) The provisions of this Agreement shall be binding upon and inure to the benefit of the parties hereto and their respective successors and assigns permitted hereby, except that the Borrower may not assign or otherwise transfer any of its rights or obligations hereunder without the prior written consent of each Lender (and any attempted assignment or transfer by the Borrower without such consent shall be null and void). Nothing in this Credit Agreement - 94 - Agreement, expressed or implied, shall be construed to confer upon any Person (other than the parties hereto, their respective successors and assigns permitted hereby and, to the extent expressly contemplated hereby, the Related Parties of each of the Administrative Agent, the Issuing Lender and the Lenders) any legal or equitable right, remedy or claim under or by reason of this Agreement. (b) Any Lender may assign to one or more assignees all or a portion of its rights and obligations under this Agreement (including all or a portion of its Commitment and the Loans at the time owing to it); provided that (i) except in the case of an assignment to a Lender or an Affiliate of a Lender, the Borrower and the Administrative Agent (and, in the case of an assignment of all or a portion of a Commitment or any Lender's obligations in respect of its LC Exposure, the LC Issuing Lender) must give its prior written consent to such assignment (which consent shall not be unreasonably withheld or delayed), (ii) except in the case of an assignment to a Lender or an Affiliate of a Lender or an assignment of the entire remaining amount of the assigning Lender's Commitment and Loans, the amount (without duplication) of the Commitment and Loans of the assigning Lender subject to each such assignment (determined as of the date the Assignment and Acceptance with respect to such assignment is delivered to the Administrative Agent) shall not be less than $10,000,000 unless each of the Borrower and the Administrative Agent otherwise consent, (iii) the parties to each assignment shall execute and deliver to the Administrative Agent an Assignment and Acceptance, together with a processing and recordation fee of $3,500, (iv) the assignee, if it shall not be a Lender, shall deliver to the Administrative Agent an Administrative Questionnaire, and (v) written notice of each assignment and the forms required under Section 2.15(e) are given to the Borrower. provided further that any consent of the Borrower otherwise required under this paragraph shall not be required if an Event of Default has occurred and is continuing.

Any assignment or transfer by a Lender of rights or obligations under this Agreement that does not comply with this paragraph (b) shall be treated for purposes of this Agreement as a sale by such Lender of a participation in such rights and obligations in accordance with paragraph (e) of this Section. (c) The Administrative Agent, acting for this purpose as an agent of the Borrower, shall maintain at one of its offices in The City of New York a copy of each Assignment and Acceptance delivered to it and a register for the recordation of the names and addresses of the Lenders, and the Commitment of, and principal amount of the Loans and LC Disbursements owing to, each Lender pursuant to the terms hereof from time to time (the "Register"). The entries in the Register shall be conclusive, and the Borrower, the Administrative Agent, the LC Issuing Lender and the Lenders may treat each Person whose name is recorded in the Register pursuant to the terms hereof as a Lender hereunder for all purposes of this Agreement, notwithstanding notice to the contrary. The Register shall be available for inspection by the Borrower, the LC Issuing Lender and any Lender, at any reasonable time and from time to time upon reasonable prior notice. (d) Upon its receipt of a duly completed Assignment and Acceptance executed by an assigning Lender and an assignee, the assignee's completed Administrative Questionnaire (unless the assignee shall already be a Lender hereunder), the processing and recordation fee referred to in paragraph (b) of this Section 10.04 and any written consent to such assignment required by paragraph (b) of this Section 10.04, the Administrative Agent shall accept such Assignment and Acceptance and record the information contained therein in the Register. No assignment shall be effective for purposes of this Agreement unless and until it has been recorded in the Register as provided in this paragraph. (e) Any Lender may, without the consent of the Borrower, the Administrative Agent or the LC Issuing Lender, sell participations to one or more banks or other entities (a "Participant") in all or a portion of such Lender's rights and obligations under this Agreement (including all or a portion of its Commitment and the Loans owing to it); provided that (i) such Lender's obligations under this Agreement shall remain unchanged, (ii) such Lender shall remain solely responsible to the other parties hereto for the performance of such obligations; and (iii) the Borrower, the Administrative Agent, the LC Issuing Lender and the other Lenders shall continue to deal solely and directly with such Lender in connection with such Lender's rights and obligations under this Agreement. Any agreement or instrument pursuant to which a Lender sells such a participation shall provide that such Lender shall retain the sole right to enforce this Agreement and to approve any amendment, modification or waiver of any provision of this Agreement; provided that such agreement or instrument may provide that such Lender will not, without the consent of the Participant, agree to any amendment, modification or waiver described in the first proviso to Section 10.02(b), or the Credit Agreement - 96 - first provision to Section 10.02(c), that affects such Participant. Subject to paragraph (f) of this Section 10.04, the Borrower agrees that each Participant shall be entitled, subject to the obligations of Section 2.17, to the benefits of Sections 2.13, 2.14 and 2.15 to the same extent as if it were a Lender and had acquired its interest by assignment pursuant to paragraph (b) of this Section 10.04. (f) A Participant shall not be entitled to receive any greater payment under Section 2.13 or 2.15 than the applicable Lender would have been entitled to receive with respect to the participation sold to such Participant, and shall be subject to the obligations of Section 2.17, unless the sale of the participation to such Participant is made with the Borrower's prior written consent. A Participant that would be a Foreign Lender if it were a Lender shall not be entitled to the benefits of Section 2.15 unless the Borrower is notified of the participation sold to such Participant and such Participant agrees, for the benefit of the Borrower, to comply with Section 2.15(e) and Section 2.17 as though it were a Lender. (g) Any Lender may at any time pledge or assign a security interest in all or any portion of its rights under this Agreement to secure obligations of such Lender, including any such pledge or assignment to a Federal Reserve Bank, and this Section shall not apply to any such pledge or assignment of a security interest; provided that no such pledge or assignment of a security interest shall release a Lender from any of its obligations hereunder or substitute any such assignee for such Lender as a party hereto. (h) Anything in this Section 10.04 to the contrary notwithstanding, no Lender may assign or participate any interest in any Loan held by it hereunder to the Borrower or any of its Affiliates or Subsidiaries without the prior consent of each Lender. SECTION 10.05. Survival. All covenants, agreements, representations and warranties made by the Credit Parties herein and in the other Loan Documents, and in the certificates or other instruments delivered in connection with or pursuant to this Agreement and the other Loan Documents, shall be considered to have been relied upon by the other parties hereto and shall survive the execution and delivery of this Agreement and the other Loan Documents and the making of any Loans and issuance of any Letters of Credit, regardless of any investigation made by any such other party or on its behalf and notwithstanding that the Administrative Agent, the LC Issuing Lender or any Lender may have had notice or knowledge of any Default or incorrect representation or warranty at the time any credit is extended hereunder, and shall continue in full force and effect so long as the principal of or any accrued interest on any Loan or any fee or any other amount payable under this Agreement or the other Loan Documents is outstanding and unpaid or any Letter of Credit is outstanding and so long as the Commitments have not expired or terminated. The provisions of Sections 2.13, 2.14, 2.15, 2.17, 3.03 and 10.03 and Article IX shall survive and remain in full force and effect regardless of the consummation of the transactions contemplated hereby, the repayment of the Loans, the expiration or termination of the Letters Credit Agreement - 97 - of Credit and the Commitments or the termination of this Agreement or any other Loan Document or any provision hereof or thereof. SECTION 10.06. Counterparts; Integration; Effectiveness. This Agreement may be executed in counterparts (and by different parties hereto on different counterparts), each of which shall constitute an original, but all of which when taken together shall constitute a single contract. This Agreement and any separate letter agreements with respect to fees payable to the Administrative Agent constitute the entire contract among the parties relating to the subject matter hereof and supersede any and all previous agreements and understandings, oral or written, relating to the subject matter hereof. Except as provided in Section 5.01, this Agreement shall become effective when it shall have been executed by the Administrative Agent and when the Administrative Agent shall have received counterparts hereof which, when taken together, bear the signatures of each of the other parties hereto, and thereafter shall be binding upon and inure to the benefit of the parties hereto and their respective successors and assigns. Delivery of an executed counterpart of a signature page of this Agreement by telecopy shall be effective as delivery of a manually executed counterpart of this Agreement. SECTION 10.07. Severability. Any provision of this Agreement held to be invalid, illegal or unenforceable in any jurisdiction shall, as to such jurisdiction, be ineffective to the extent of such invalidity, illegality or unenforceability without affecting the validity, legality and enforceability of the remaining provisions hereof; and the invalidity of a particular provision in a particular jurisdiction shall not invalidate such provision in any other jurisdiction. SECTION 10.08. Right of Setoff. If an Event of Default shall have occurred and be continuing, each Lender is hereby authorized at any time and from time to time, to the fullest extent permitted by law, to set off and apply any and all deposits (general or special, time or demand, provisional or final) at any time held and other indebtedness at any time owing by such Lender to or for the credit or the account of the Borrower against any of and all the obligations of the Borrower now or hereafter existing under this Agreement held by such Lender, irrespective of whether or not such Lender shall have made any demand under this Agreement and although such obligations may be unmatured. The rights of each Lender under this Section 10.08 are in addition to any other rights and remedies (including other rights of setoff) which such Lender may have. SECTION 10.09. Governing Law; Jurisdiction; Consent to Service of Process. (a) This Agreement shall be construed in accordance with and governed by the law of the State of New York. (b) Each party hereto hereby irrevocably and unconditionally submits, for itself and its property, to the nonexclusive jurisdiction of the Supreme Court of the State of New Credit Agreement - 98 - York sitting in New York County and of the United States District Court of the Southern District of New York, and any appellate court from any thereof, in any action or proceeding arising out of or relating to this Agreement or the other Loan Documents, or for recognition or enforcement of any judgment, and each of the parties hereto hereby irrevocably and unconditionally agrees that all claims in respect of any such action or proceeding may be heard and determined in such New York State court (or, to the extent permitted by law, in such Federal court). Each of the parties hereto agrees that a final judgment in any such action or proceeding shall be conclusive and may be enforced in other jurisdictions by suit on the judgment or in any other manner provided by law. Nothing in this Agreement shall affect any right that the Administrative Agent, the LC Issuing Lender or any Lender may otherwise have to bring any action or proceeding relating to this Agreement against any Credit Party or its properties in the courts of any jurisdiction.

Each of the parties hereto hereby irrevocably waives, to the fullest extent permitted by law, the defense of an inconvenient forum to the maintenance of such action or proceeding in any such court.

                                   PREAMBLE


      1.  Formation  of the Plan.  The Plan is a  successor  plan to the  former
"Savings Plan for Employees of NL Industries, Inc.", which is referred to herein
as the  "Predecessor  Plan." In connection with the Plan of  Restructuring of NL
Industries,  Inc. which was approved by  shareholders  on December 22, 1988, the
Predecessor   Plan  was  renamed  the  Savings  Plan  for  Employees  of  Baroid
Corporation  and  adopted  and  assumed  by  Baroid  Corporation.   Pending  the
implementation  of the Plan,  eligible  employees  of NL  Industries,  Inc.  and
subsidiaries  formerly eligible to participate in the Predecessor Plan continued
to participate in the  Predecessor  Plan. The Plan was established as of January
1, 1989 to permit eligible  employees of NL Industries,  Inc. and  participating
subsidiaries to continue their  participation  in a tax-qualified  savings plan.
The Plan includes  amendments which reflect the  restructuring and other changes
which were communicated to eligible employees in November of 1988.  Accordingly,
the Plan governs the rights and obligations of the Company and Plan participants
for  all  periods  on  and  after  January  1,  1989,  except  with  respect  to
participants' accounts held in Investment Funds of the Predecessor Plan, pending
their transfer to the Plan. All  participants  who were  participants  under the
Predecessor Plan automatically  become  participants under the new Plan. Account
balances  under the  Predecessor  Plan were  transferred  to the Plan as soon as
practicable after the implementation of the Plan.

      2. Change of Investment Structure.  Effective as of July 1, 1990, the Plan
was amended and restated to restructure the investments  available,  and to make
related and other amendments.

      3. Baroid Stock Fund. Baroid Corporation restructured in 1990, as a result
of which holders of the Common Stock of Baroid Corporation under the Plan became
holders of shares of both Baroid  Corporation  and Tremont  Corporation.  Baroid
Corporation  was later  acquired  by or merged  with  Dresser  Industries,  Inc.
Therefore,  the Baroid Stock Fund was renamed the Dresser/Tremont  Stock Fund to
reflect the names of the companies whose shares are held in that fund.

      4. IRS  Required  changes.  As part of their  review  of the  amended  and
restated Plan in 1991, the Internal  Revenue  Service  required  several wording
changes that had no operational  effect, but also required  substantial  changes
the forfeitures provisions of Section 8.4.

      5. TRA 86 Update.  To meet the  requirements of the Tax Reform Act of 1986
and subsequent legislation and regulations, the Plan was amended and restated in
December, 1994.

      6. Additional Defined Contribution  Feature.  Effective April 1, 1996, the
defined  benefit  plan was frozen and the Savings Plan amended to provide for an
additional Company Contribution,  to be called a "pension feature contribution";
this  contribution is a profit sharing  contribution  not subject to the minimum
funding  standards of Section 412 of the  Internal  Revenue  Code.  The Plan was
renamed the NL Industries,  Inc. Retirement Savings Plan to reflect inclusion of
the new benefit

                                      vi





formula.  Other minor changes,  including  deleting certain obsolete portions of
the historical plan document, are made at the same time.

                                   ARTICLE I

                                    PURPOSE

      1.1 The purpose of the NL Industries,  Inc., Retirement Savings Plan is to
provide  eligible  employees  with a  convenient  way to save on a  regular  and
long-term  basis by providing such  employees with a beneficial  interest in the
profits of the  business,  all as set forth  herein  and in the Trust  Agreement
adopted in connection with the Plan. The Plan and its related Trust are intended
to qualify as a plan and trust which meet the  requirements of Sections  401(a),
401(k) and 501(a), respectively, of the Internal Revenue Code of 1986, as now in
effect  or  hereafter  amended,  and  all  other  applicable  provisions  of law
including,  without  limitation,  the Employee Retirement Income Security Act of
1974, as now in effect or hereafter amended.

all as determined under Sections 414(b), (c) and (m) of the Code,  respectively;
provided,  however,  that for purposes of  determining  the annual  contribution
limitations  set  forth in  Article  XIV,  such  determination  shall be made in
accordance with Section 415(h) of the Code.

      2.2   "Authorized Leave of Absence" means any absence from employment:

            (a) Authorized by the Committee for education  purposes or by reason
      of family  obligations,  sickness,  short  term  disability,  accident  or
      emergency  (including  any  leave of  absence  to which  the  Employee  is
      eligible under the Family and Medical Leave Act of 1993); or

            (b) On account of a period of  military  service  required by law or
      under leave  granted by the  Committee,  provided the Employee  returns to
      employment with the Company or an Affiliated  Company within 90 days after

      his right to reemployment is legally protected.

to all Participants in similar circumstances.

      2.3  "Basic   Contributions"   means  the  aggregate  of  a   Contributing

Participant's  Compensation  which  he  elects  to  reduce  in  accordance  with
Paragraph 4.2 hereof and have contributed to the Trust Fund on his behalf by his
Employer on a pre-tax basis, in compliance with the provisions of Section 401(k)
of the Code.


                                     II-1





      2.6  "Beneficiary"  means the  Spouse  of the  Participant  if  surviving;
provided,  however,  that if there is no  surviving  Spouse or if the  surviving
Spouse cannot be located, the person or persons designated by the Participant in
the form of a Qualified Election,  as such term is defined in Paragraph 2.31, to
receive any death benefit  payable  hereunder.  A Participant may also designate
any person or persons as his Beneficiary in the form of a written designation to
receive any death benefit payable  hereunder,  provided he obtains the notarized
written  consent  of  his  Spouse.  A  Participant  may  revoke  or  change  his
Beneficiary  designation only with the consent of the Spouse by filing a revised
designation  with the  Committee.  The last  such  designation  received  by the
Committee shall be controlling;  provided, however, that no designation,  change
or revocation thereof, shall be effective unless received by the Committee prior
to the  Participant's  death, and in no event shall it be effective as of a date
prior to such receipt. In the absence of an effective designation or if no named
beneficiary  shall  survive  the  Participant,  the  Beneficiary  shall  be  the
Participant's  Spouse, or, if there is no Spouse, then the following persons (if

(ii) parents, in equal shares, (iii) the persons designated as beneficiary under
the  group  life  insurance  plan of the  Employer,  and (iv) the  Participant's
estate.  If the  Committee  is in doubt as to the right of any person to receive
such amount, the Committee may direct the Trustee to retain such amount, without
liability for any interest thereon, until the rights thereto are determined,  or
the  Committee  may direct  the  Trustee  to pay such  amount  into any court of
appropriate  jurisdiction and such payment shall be a complete  discharge of the
liability of the Plan and the Trust therefor.

      2.7 "Board"  means the Board of  Directors  of the Company as  constituted
from time to time, or the duly appointed delegate of such Board of Directors.

      2.8 "Break in Service"  means any Plan Year during which an Employee fails
to  receive  credit  for at least  three (3)  Months of  Service or 501 Hours of
Service,  except that a Break in Service shall not be deemed to occur on account
of any Authorized Leave of Absence. Solely for purposes of determining whether a
Break in Service has  occurred in any Plan Year,  an Employee who is absent from
work on account of a "maternity or paternity absence" shall be credited with the
number of Hours of Service which would have been completed but for such absence,
or, if the Committee is unable to determine  such Hours of Service,  eight Hours
of Service for each day of such absence;  provided,  however,  that no more than
501 hours  shall be  credited  hereunder  on  account of any such  absence,  and
further  provided  that the  Employee  furnishes  to the  Committee  such timely
information  as may be required by the  Committee  to properly  administer  this
provision.  Hours of Service for a  "maternity  or paternity  absence"  shall be
credited  entirely in the Plan Year in which the absence  begins if necessary to
prevent  the  occurrence  of a Break in Service  in such year,  or, in any other
case, in the immediately following Plan Year. A "maternity or paternity absence"
shall mean any  absence  from work by reason of the  Employee's  pregnancy,  the
birth of the  Employee's  child,  the  placement of a child with the Employee in
connection  with the adoption of such child by the Employee,  or for purposes of
caring  for any such child for the period  immediately  following  such birth or
placement.


                                     II-2





      2.9 "Code" means the Internal Revenue Code of 1986, as now in effect or as

time be amended or renumbered.

Industries, Inc. as established in accordance with Article XI hereof.

for  stock  splits,  stock  dividends,  reclassifications  and  similar  changes

employees  which is  ineligible  to  participate  in the Plan.  For  purposes of
subparagraph   (c),   employment  with  an  Affiliated   Company  which  is  not
participating  in the Plan or as an employee  ineligible to  participate  in the
Plan

                                    III-3





shall  count as Hours of Service  and Months of Service  toward  satisfying  the
requirement of Paragraph 3.1.

                                    III-4





                                  ARTICLE IV

                           PARTICIPANT CONTRIBUTIONS

      4.1 Amount of Basic After-Tax Contributions:  Subject to the provisions of
Paragraph  5.2(c)(i)  and Article  XIV,  any  Employee who is, or is eligible to
become, a Contributing  Participant may make through payroll  deductions,  Basic
After-Tax  Contributions,  for any Plan  Year,  equal to any  percentage  of his
Compensation,  in  increments  of 0.5%,  from 1% up to and including 8% (or such
other maximum amount as may be established by the Committee) less the percentage
of  Compensation  elected as Basic Pre-Tax  Contributions  pursuant to Paragraph
4.2, if any.

      4.2   Amount of Basic Pre-Tax Contributions:

            (a) Contribution Limits:  Subject to the provisions of Paragraph 4.5
      and  Article  XIV,  any  Employee  who is, or is  eligible  to  become,  a
      Contributing  Participant may elect, in accordance with procedures adopted
      by the  Company,  to reduce  his  Compensation  by an amount  equal to any
      percentage, in increments of 0.5%, from 1% up to and including 8%, or such
      other maximum amount as may be  established  by the  Committee;  provided,
      however, that the maximum amount elected as Basic Pre-Tax Contributions in
      no event shall exceed the difference between (i) 8% (or such other maximum
      amount as may be  established by the Committee) and (ii) the percentage of
      Compensation  elected  as  Basic  After-Tax   Contributions   pursuant  to
      Paragraph 4.1, if any. Subject to subparagraph  4.5(b),  the amount of any
      such  reduction  shall  be  contributed  to  the  Plan  as  Basic  Pre-Tax
      Contributions on behalf of such Contributing  Participant by his Employer.
      Notwithstanding the foregoing, Basic Pre-Tax Contributions in any calendar
      year shall not exceed the limitation on elective  deferrals  under Section
      402(g)(1)  of the Code  adjusted  for  increases  in the cost of living in
      accordance with Section 402(g)(5) of the Code.

            (b) Refund of Excess Contributions:  In the event that the aggregate
      amount  of Basic  Pre-Tax  Contributions  for a  Participant  exceeds  the
      limitation in the previous sentence, the amount of such excess,  increased
      by any  income and  decreased  by any losses  attributable  thereto  (but,
      effective  January 1, 1992,  before the gap period  between the end of the
      calendar  year and the date of  distribution),  shall be  refunded  to the
      Participant  no later than the April 15th of the calendar  year  following
      the calendar year for which the Basic Pre-Tax  Contributions were made. If
      a Participant also participates,  in any calendar year, in any other plans
      subject to the limitations set forth in Section 402(g) of the Code and has
      made excess  deferrals  under this Plan when combined with the other plans
      subject  to  such  limits,  to the  extent  the  Participant,  in  writing
      submitted to the  Committee no later than the March 1 of the calendar year
      following the calendar year for which the Basic Pre-Tax Contributions were
      made, designates any Basic Pre-Tax Contributions under this Plan as excess
      deferrals,  the amount of such designated excess,  increased by any income
      and decreased by any losses attributable thereto, shall be refunded to the
      Participant  no later than the April 15 of the calendar year following the
      calendar year for which the Basic Pre-Tax Contributions were

                                     IV-1





      made. Alternatively,  a Participant may request refund of excess deferrals
      before the end of the Plan Year.

      4.3 Supplemental Contributions:  Subject to the provisions of Article XIV,
a Participant who is an Employee and whose Basic  Contributions  are at least 8%
may elect to make Supplemental  After-Tax or Supplemental Pre-Tax  Contributions
through  payroll  deductions.  A Participant  who is an Employee and whose Basic
Contributions  are  less  than  8% may  elect  to  make  Supplemental  After-Tax
Contributions by personal check.  Supplemental  Pre-Tax  Contributions  shall be
made  in  accordance  with  procedures  adopted  by  the  Company.  Supplemental
Contributions  are not  matched by the  Company.  The  amount of a  Contributing
Participant's  Supplemental  Contributions may be made by payroll  deductions in
increments  of 0.5%  from 1% to 4% of  Compensation,  or by  personal  check  in
multiples of $100, or in such other percentages or amounts as may be established
by the Committee.

      If Basic Contributions are reduced below 8%, a Participant's  Supplemental
Contributions  by  payroll  deduction  will  be  suspended.   Such  Supplemental
Contributions  may  resume  once  Basic  Contributions  equal at least  8%.  The
provisions of Section 4.2(b) apply to Supplemental Pre-Tax Contributions, also.

      4.4  Separate   Accounting:   The  Committee  and  the  Trustee  shall  be
responsible for maintaining  separate records of the Basic After-Tax and Pre-Tax
Contributions,  Supplemental  After-Tax and Pre-Tax  Contributions  and Rollover
Contributions  (including  Direct Rollovers and direct  transfers) made by or on
behalf of the Participant and paid over to the Trustee.  All amounts contributed
by or on behalf of the  Participant  to the Trust  Fund with  respect to any pay
period shall be allocated to the  Participant's  account as soon as  practicable
after the end of the pay  period in  respect  of which the  payroll  deductions,
salary reductions or cash payments are effectuated.

      4.5  Special  Provisions   Related  to  Basic  and  Supplemental   Pre-Tax
Contributions:

            (a)  Vesting  and  Withdrawal  Limitation:  Basic  and  Supplemental
      Pre-Tax Contributions, including increments earned thereon, shall be fully
      vested  at all  times  and may not be  withdrawn  by or  distributed  to a
      Participant,  except as permitted by an election  made pursuant to Section
      9.6,  until the earliest to occur of his  Retirement,  death,  Disability,
      separation from service, attainment of age 59 1/2 or hardship.

            (b)  (i) ADP  Test:  Notwithstanding  any  other  provision  of this
            Article  IV, the actual  deferral  percentage  for the Plan Year for
            Highly  Compensated  Employees  shall not exceed the  greater of the
            following actual deferral  percentage tests: (a) the actual deferral
            percentage  for such Plan Year of those  eligible  Employees who are
            not Highly  Compensated  Employees  multiplied  by 1.25;  or (b) the
            actual  deferral  percentage  for the Plan  Year of  those  eligible
            Employees  who are not Highly  Compensated  Employees  multiplied by
            2.0,  provided  that  the  actual  deferral  percentage  for  Highly
            Compensated Employees does not exceed the actual deferral

                                     IV-2





            percentage  for  such  other  eligible  Employees  by  more  than  2
            percentage  points.  For  purposes  of this  Article IV, the "actual
            deferral percentage" for a Plan Year means, for each specified group
            of employees,  the average of the ratios (calculated  separately for
            each Employee in such group) of (a) the amount of the  Participant's
            Basic and Supplemental  Pre-Tax  Contributions for the Plan Year, to
            (b) the  amount of the  Participant's  Compensation  (as  defined in
            Section  414(s)  of  the  Code)  for  the  Plan  Year.  An  eligible
            Employee's  actual  deferral  percentage  shall  be zero if no Basic
            Pre-Tax Contribution or Supplemental Pre-Tax Contribution is made on
            his behalf for such Plan Year.

                  (ii)  Recharacterization  and Refund  (Leveling  Method):  The
            Committee  shall  determine  as of the end of the Plan Year,  and at
            such  time or times in its  discretion,  whether  one of the  actual
            deferral  percentage  tests specified in  subparagraph  4.5(b)(i) is
            satisfied for such Plan Year. This determination shall be made after
            first  determining  the  treatment  of excess  deferrals  within the
            meaning of Section  402(g) of the Code under  Paragraph  4.2. In the
            event  that  neither of such  actual  deferral  percentage  tests is
            satisfied,  the Committee shall, to the extent permissible under the
            Code   and   the   Regulations,   and  to  the   extent   any   such
            recharacterization  would  not  cause a  violation  of  subparagraph
            5.2(a) or,  together  with Basic  After-Tax  Contributions  actually
            made, exceed the limitations on Basic After-Tax Contributions stated
            in Paragraph 4.1 determined  prior to  application  of  subparagraph
            5.2(a),  if the  Participant so elects,  recharacterize  such excess
            contributions as Basic or Supplemental After-Tax  Contributions,  in
            the manner  described in  subparagraph  4.5(b)(iv) or, to the extent
            such  recharacterization is not possible or the Participant does not
            so elect, refund the excess contributions in the manner described in
            subparagraph  4.5(b)(v).  For purposes of this  Article IV,  "excess
            contributions"  means,  with respect to any Plan Year, the excess of
            the aggregate amount of Basic and Supplemental Pre-Tax Contributions
            (and any  earnings  and  losses  allocable  thereto  but,  effective
            January  1,  1992,  before  the gap  period  between  the end of the
            calendar year and the date of distribution) made on behalf of Highly
            Compensated Participants for such Plan Year, over the maximum amount
            of such  contributions  that  could  be  made  to such  Participants
            without  violating  the  requirements  of  subparagraph   4.5(b)(i),
            determined by reducing Basic and Supplemental Pre-Tax  Contributions
            made on behalf of Highly  Compensated  Participants  in order of the
            actual  deferral  percentages  beginning  with the  highest  of such
            percentages.  The  reduction  shall be  determined  by the  leveling
            method,  under  which  the  actual  deferral  ratio  of  the  Highly
            Compensated  Employee  with the  highest  actual  deferral  ratio is
            reduced to the extent required to (i) enable the Plan to satisfy the
            ADP test, or (ii) cause such Highly  Compensated  Employee's  actual
            deferral ratio to equal the ratio of the Highly Compensated Employee
            with the next highest actual deferral ratio.  This leveling  process
            shall be repeated until the Plan  satisfies the ADP test.  Provided,
            however,  that for years after 1996, if a different  leveling method
            is mandated by the Code,  such  different  leveling  method shall be
            used instead.

                                     IV-3





                  (iii)  Forfeiture  of  Matching  Contributions:  If any  Basic
            Pre-Tax  Contributions are to be refunded as an excess contribution,
            the corresponding matching contributions that were contributed under
            Section 5.1 (and any  earnings  and losses  attributed  thereto but,
            effective  January 1, 1992, before the gap period between the end of
            the calendar year and the date of distribution) will be forfeited.

                  (iv) Tax Treatment of Recharacterized Deferrals: To the extent
            provided in subparagraph 4.5(b)(ii), in accordance with the Code and
            the Regulations,  if a Highly  Compensated  Participant so elects in
            writing no later than the 15th day of the second  month  immediately
            following   the  end  of  the  Plan  Year  for  which  such   excess
            contributions were made, the Committee shall  recharacterize  excess
            contributions  of  such  Participant  for a Plan  Year as  Basic  or
            Supplemental  After-Tax   Contributions  in  order  to  satisfy  the
            requirements of subparagraph 4.5(b)(i), in which event the amount of
            excess  contributions  so  recharacterized   shall,  to  the  extent
            permitted by the Code and the Regulations, be treated as having been
            refunded to the Participant and then  contributed by the Participant
            as Basic or Supplemental  After-Tax  Contributions,  as appropriate.
            Earnings related to any recharacterized  amount shall not be treated
            as a recharacterized amount.

                  (v) Timing of  Refunds:  If a Highly  Compensated  Participant
            does not elect recharacterization under subparagraph 4.5(b)(iv), or,
            if required in order to comply with the  provisions of  subparagraph
            4.5(b)(i),   and  the  Code,  the  Committee   shall  refund  excess
            contributions  for a Plan  Year.  The  distribution  of such  excess
            contributions  shall be made to Highly  Compensated  Participants to
            the  extent  practicable  before  the  15th day of the  third  month
            immediately   following   the  Plan  Year  for  which  such   excess
            contributions  were made,  but in no event later than the earlier of
            (a) the end of the Plan Year  following such Plan Year or (b) in the
            case of the termination of the Plan in accordance with Article XIII,
            no  later  than  the  end of  the  twelve-month  period  immediately
            following the date of such termination.  Any such distribution shall
            be made to each Highly  Compensated  Participant on the basis of the
            respective portions of such amounts attributable to each such Highly
            Compensated Participant.

                  (vi)  Effect  of  Prior   Distribution  of  Excess  Deferrals:
            Notwithstanding  the  foregoing   provisions  of  this  subparagraph
            4.5(b), the amount of excess  contributions to be recharacterized or
            distributed  pursuant to subparagraph  4.5(b)(iii) with respect to a
            Participant for a Plan Year shall be reduced by any excess deferrals
            previously distributed to such Participant for such Plan Year.

                  (vii)    Continued    Impact    of    Excess    Contributions:
            Notwithstanding  the  foregoing  provisions of this  Paragraph  4.5,
            excess  contributions that are  recharacterized  shall then be taken
            into  account for purposes of Paragraph  5.2,  shall  continue to be
            subject to Paragraph 8.1 and Paragraph 10.3, and shall continue to

                                     IV-4





            count toward the limits in Paragraph 14.2. Excess contributions that
            are refunded  shall continue to count toward the limits in Paragraph
            14.2.

                  (viii)Family Aggregation Rules: Only to the extent that family
            aggregation  rules are mandated by the Code,  if an eligible  Highly
            Compensated  Employee is subject to the family  aggregation rules of
            Section  414(q)(6)  of the Code  because  such  employee is either a
            five-percent  owner  or one  of  the  ten  most  Highly  Compensated
            Employees,  the combined  actual deferral ratio for the family group
            (which is  treated  as one  Highly  Compensated  Employee)  shall be
            determined   by  combining  the  Basic  and   Supplemental   Pre-Tax
            Contributions,   Compensation  and  amounts  treated  as  Basic  and
            Supplemental  Pre-Tax  Contributions  of  all  the  eligible  family
            members.

                  The Basic and Supplemental Pre-Tax Contributions, Compensation
            and amounts treated as Basic and Supplemental Pre-Tax  Contributions
            of all  family  members  shall be  disregarded  for the  purpose  of
            determining the actual deferral percentage for the group of eligible
            Employees who are not Highly Compensated Employees.

                  If an Employee is  required  to be  aggregated  as a member of
            more than one family group in a plan, all eligible Employees who are
            members of those family groups that include that  Employee  shall be
            aggregated as one family group.

                  (ix) Family  Correction:  The  determination and correction of
            excess  contributions of a Highly Compensated  Employee whose actual
            deferral ratio is determined under  subparagraph  4.5(b)(viii) shall
            be  accomplished  as  follows:  the actual  deferral  ratio shall be
            reduced as required  under  subparagraph  4.5(b)(ii)  and the excess
            contributions  for the  family  unit  shall be  allocated  among the
            family members in proportion to the Basic and  Supplemental  Pre-Tax
            Contributions  of each family  member that are combined to determine
            the actual deferral ratio.

      4.6 Change in Amount of  Contributions:  A  Contributing  Participant  may
change  the rate of his Basic or  Supplemental  Contributions  for any  calendar
month by filing the appropriate Plan form with the local  administrator at least
15 days prior to the first day of any such  calendar  month for which the change
in payroll  deductions is intended to be  effective.  All elections of Basic and
Supplemental  Contribution  rates made  under the Plan  shall  remain in effect,
notwithstanding  any change in Compensation,  until changed as permitted in this
Paragraph 4.6 or Paragraph 4.5.

      4.7  Suspension of Basic or  Supplemental  Contributions:  A  Contributing
Participant may suspend his Basic or Supplemental  Contributions  to the Plan by
filing the appropriate  Plan form with the local  administrator at least 15 days
prior to the first day of the pay period for which such  suspension  is intended
to be effective. Suspension of Basic After-Tax Contributions shall not prevent a
Contributing  Participant  from  continuing  or  increasing  his  Basic  Pre-Tax
Contributions

                                     IV-5





and suspension of Basic Pre-Tax  Contributions  shall not prevent a Contributing
Participant from continuing or increasing his Basic After-Tax Contributions.

      4.8  Remittance  of  Contributions  to Trustee:  Basic  Contributions  and
Supplemental  Contributions  shall  be  remitted  to  the  Trustee  as  soon  as
practicable after the end of the month in which the payroll deductions, personal
checks,  salary  reductions  or cash payments are  effectuated,  but in no event
later than 90 days from the date such contributions are received by the Employer
(in the case of Basic and Supplemental  After-Tax  Contributions) or the date on
which such contributions  would otherwise have been paid to the Employee in cash
(in the case of Basic and  Supplemental  Pre-Tax  Contributions).  The aggregate
amounts  contributed  hereunder,  shall  be  employed  by the  Trustee  to  make
purchases for the  Investment  Fund or Funds in accordance  with the  respective
investment  elections of each Contributing  Participant for such pay period. All
such  contributions  shall be  allocated  to the  accounts  of each  Participant
established in accordance with Article VII.

      4.9 Cessation of  Contributions  Made by a Contributing  Participant:  All
Contributions of a Contributing Participant shall cease effective with the first
day of the pay period coincident with or next following the date of:

            (a) the timely  filing of a notice of voluntary  suspension of Basic
      Contributions as described in Paragraph 4.7;

            (b) the election to make certain withdrawals pursuant to Article X;

            (c) the involuntary  suspension of Basic Contributions  because of a
      transfer in  employment  or  employment  classification  as  described  in
      subparagraph 3.4(b); or

            (d)  the   termination  of  employment  for  any  reason   including
      Retirement, death or Disability.

      Notwithstanding  the  foregoing,  subparagraph  (b) shall not affect Basic
Pre-Tax Contributions, except as provided in Paragraph 10.2.

      4.10  Participant Rollover Contributions:

            (a)  General:  With  the  consent  of  the  Committee,  an  Employee
      described in subparagraphs  3.1(a) or (b) may contribute cash to the Trust
      Fund  other  than as Basic or  Supplemental  Contributions  provided  such
      contribution   constitutes   a  Rollover   Contribution   (as  defined  in
      subparagraph  (b) of this  Paragraph) or a Direct  Rollover (as defined in
      subsection  (c) of this  Paragraph)  or a direct  transfer  (as defined in
      subparagraph (d) of this Paragraph).  All Rollover  Contributions,  Direct
      Rollovers,  and direct  transfers  to the Trust Fund shall be allocated to
      the  Employee's  account  as of the  Valuation  Date  coincident  with  or
      immediately  preceding  the  date  of  the  contribution.  To  the  extent
      prohibited  under the Code, no Rollover  Contribution,  Direct Rollover or
      direct transfer shall be allowed if the

                                     IV-6





      assets involved are is  attributable  directly or indirectly to a trust or
      annuity  forming part of a plan under which the Employee was a 5% owner at
      the time the  distribution  from  such  trust or  annuity  was  made.  For
      purposes of the preceding  sentence,  a 5% owner shall mean any individual
      who was a 5% owner  (within  the  meaning of Section  416(i)(1)(B)  of the
      Code) of the employer  maintaining  such other plan at any time during the
      five plan years preceding the plan year in which the distribution is made.
      If an Employee  described in  subparagraphs  3.1(a) or (b) is permitted to
      make such a Rollover Contribution, Direct Rollover or direct transfer, the
      Committee shall obtain such evidence,  assurances or  certifications as it
      may deem  necessary  from such  Employee to establish to its  satisfaction
      that the  amounts to be  contributed  qualify as  Rollover  Contributions,
      Direct  Rollovers or direct  transfers within the meaning of subparagraphs
      (b) or (c) and will not  affect the  qualification  of the Plan or the tax
      exempt  status of the Trust Fund under  Sections  401(a) and 501(a) of the
      Code, respectively,  or substantially increase the administrative expenses
      of the Plan.  The amount so transferred  must consist of cash  distributed
      from such other plan or any portion of the cash  proceeds from the sale of
      distributed  property other than cash, to the extent  permitted by Section
      402(a)(6)(D) of the Code.

            (b) Rollover Contributions: As used in this Paragraph 4.10, the term
      "Rollover Contribution" shall mean the following:

                  (i) all or any portion of a "qualified total distribution" (as
            said term is defined in Section  402(a)(5)(E)(i)(I)  and (II) of the
            Code inclusive of Section 402(a)(6) of the Code, and, after December
            31, 1984, including a rollover distribution  attributable to a trust
            forming  part of a plan under  which the  Employee  was an  employee
            within the meaning of Section  401(c)(1)  at the time  contributions
            were made on his  behalf)  which is  contributed  to the Trust  Fund
            within 60 days or receipt of the distribution from a trust described
            in  Section  401(a) of the Code and  exempt  from tax under  Section
            501(a) of the Code. A qualified total distribution shall not include
            any amount  considered  to be  contributed  by the  Employee  to the
            qualified trust described above;

                  (ii) an  amount  (described  in  Section  408(d)(3)(A)(ii)  or
            Section  409(b)(3)(C) of the Code) which is contributed to the Trust
            Fund  and  represents  all  or any  portion  of  the  amount  of the
            Employee's  distribution  from an individual  retirement  account or
            individual retirement annuity (defined in Sections 408(a) and 408(b)
            of the Code,  respectively) the value of which account or annuity is
            attributable  solely to a qualified total  distribution  received by
            such Employee from a trust  described in Section  401(a) of the Code
            and  exempt  from tax under  Section  501(a) of the Code,  and which
            amount  is  contributed  to the  Trust  Fund  within  60 days of the
            distribution from the Employee's individual account or annuity.


            (c) Direct  Rollovers:  Special Rules  Regarding  Eligible  Rollover
      Distributions:

                                     IV-7





                  (i) This Section 4.10(c) applies to  distributions  made on or
            after January 1, 1993.  Notwithstanding any provision of the Plan to
            the contrary that would  otherwise  limit a  distributee's  election
            under this Section 4.10(c), a distributee may elect, at the time and
            in the  manner  prescribed  by the  Committee,  to have any  portion
            (provided  that  such  portion  is at  least  $500)  of an  eligible
            rollover  distribution paid directly to an eligible  retirement plan
            specified by the distributee in a Direct  Rollover.  Only one Direct
            Rollover shall be allowed for each eligible rollover distribution.

                  (ii)  Definitions:

                        (a) Eligible rollover distribution: An eligible rollover
                  distribution  is any  distribution of all or any portion (that
                  is at  least  $500)  of  the  balance  to  the  credit  of the
                  distributee,  except  that an eligible  rollover  distribution
                  does not include: (1) any distribution that is one of a series
                  of substantially  equal periodic payments (not less frequently
                  than annually)  made for the life (or life  expectancy) of the
                  distributee or the joint lives (or joint life expectancies) of
                  the distributee and the distributee's  designated beneficiary,
                  or for a  specified  period  of ten  years  or  more;  (2) any
                  distribution to the extent such distribution is required under
                  Section  401(a)(9)  of  the  Code;  (3)  the  portion  of  any
                  distribution   that  is  not   includable   in  gross   income
                  (determined  without regard to the exclusion of new unrealized
                  appreciation with respect to employer securities), and (4) any
                  other amounts that are treated as not being eligible  rollover
                  distributions under Temporary  Regulation Section 1.401(a)(31)
                  - IT or other guidance issued under Section  401(a)(31) of the
                  Code.

                        (b) Eligible  retirement  plan:  An eligible  retirement
                  plan is an individual  retirement account described in Section
                  408(a) of the Code, an individual retirement annuity described
                  in Section  408(b) of the Code,  an annuity plan  described in
                  Section 403(a) of the Code, or a qualified  trust described in
                  Section  401(a) of the Code  that  accepts  the  distributee's
                  eligible  rollover  distribution.  However,  in the case of an
                  eligible  rollover  distribution to the surviving  spouse,  an
                  eligible  retirement plan is an individual  retirement account
                  or individual retirement annuity.

                  (iii)  Distributee:  A  distributee  includes  an  Employee or
            former Employee.  In addition,  the Employee's or former  Employee's
            surviving spouse and the Employee's or former  Employee's  spouse or
            former spouse who is the alternate payee under a qualified  domestic
            relations  order,  as  defined in  Section  414(p) of the Code,  are
            distributees  with  regard to the  interest  of the spouse or former
            spouse.


                                     IV-8





                  (iv) Direct  Rollover:  A Direct  Rollover is a payment by the
            Plan to the eligible retirement plan specified by the distributee.

            (d) Direct Transfers:  Subject to subparagraph  4.10(e), in addition
      to the Rollover  Contribution  described in subparagraphs (a) and (b), and
      the Direct  Rollover  described in  subparagraph  (c), the  Committee,  in
      accordance  with a uniform  and  nondiscriminatory  policy  applicable  to
      Employees  described  in  subparagraphs  3.1(a)  and (b),  may  direct the
      Trustee to accept a cash  contribution  transferred  directly to the Trust
      Fund from the trustee of another trust  described in Section 401(a) of the
      Code and  exempt  from tax under  Section  501(a) of the Code on behalf of
      such Employee who  participated in that trust.  Prior to the acceptance of
      such a contribution  the Committee shall obtain such evidence,  assurances
      or   certifications   as  it  may  deem  necessary  to  establish  to  its
      satisfaction  that  the  amount  to be  contributed  will not  affect  the
      qualification of the Plan or the tax-exempt status of the Trust Fund under
      Sections  401(a) and 501(a) of the Code,  respectively,  or  substantially
      increase the administrative expenses of the Plan.

            (e) Restrictions:  Notwithstanding  anything herein to the contrary,
      the  Committee,  pursuant  to  uniform  and  nondiscriminatory  guidelines
      established by it, shall not permit any direct or indirect  transfers from
      another trust  described in Section 401(a) of the Code and exempt from tax
      under Section  501(a) of the Code,  which provides for a life annuity form
      of payment to the  Employee,  other than the trust  under the  Predecessor
      Plan.




                                     IV-9





                                   ARTICLE V

                            EMPLOYER CONTRIBUTIONS

      5.1   Employer Contributions:

            (a)  Employer  Matching  Contributions:  For  each  plan  year,  and
      generally  during  the  first  quarter  of the  Plan  Year,  the  Board of
      Directors in its sole  discretion,  shall  establish  three  profitability
      thresholds which are referred to herein as "Level A", "Level B" and "Level
      C". The highest Profitability Level which is attained, as determined at or
      after the end of the Plan Year,  shall  determine the Employer's  matching
      contribution obligations to the Plan.

            Subject  to the  provisions  of Article  XIV,  each  Employer  shall
      contribute to the Trust Fund based upon the  Profitability  Level attained
      in accordance with the following formula:


                  (i)  Twenty-five  cents for each one dollar of a  Contributing
            Participant's Basic Contributions which are based on the first 8% of
            his Compensation,  provided the  Profitability  Level is equal to or
            above Level A but below Level B;

                  (ii)  Fifty  cents  for  each  one  dollar  of a  Contributing
            Participant's  Basic Contributions which is based on the first 8% of
            his  Compensation  provided the  Profitability  Level is equal to or
            above Level B but below Level C;

                  (iii) Seventy-five cents for each one dollar of a Contributing
            Participant's  Basic Contributions which is based on the first 8% of
            his  Compensation  provided the  Profitability  Level is equal to or
            above Level C.

            In a "below A" year,  no  Employer  Matching  Contributions  will be
      contributed to the Plan or allocated to any Participant's account.

            No Employer Matching  Contributions  shall be made with respect to a
      Contributing   Participant's  Supplemental   Contributions.   No  Employer
      matching  contributions  shall  be made  with  respect  to a  Contributing
      Participant's Basic After-Tax  Contributions to the extent that such Basic
      After-Tax Contributions were withdrawn before the end of the calendar year
      in which they were contributed.

            (b) Employer Pension Feature Contributions:  Effective April 1, 1996
      for  periods  after  March  31,  1996,   the  Employer   Pension   Feature
      Contribution  shall be that amount which, in combination with forfeitures,
      provides for a percentage of  Compensation  profit  sharing  allocation as
      calculated  for each  Participant  who is an active  employee  during  the
      calendar year, by adding together two formulas, "A" and "B", where:

                                     V-1





      "A" is 3% of the Participant's Compensation for the calendar year, and

      "B" is calculated in accordance with the following steps:

            1) The prospective  benefit that would have been earned (starting on
            April 1, 1996) from the Retirement Programs of NL Industries,  Inc.,
            for Salaried  Employees if that plan had not been frozen as of April
            1, 1996,  for service on and after April 1, 1996,  was calculated as
            of March 31, 1996,  using data  available on January 22, 1996.  1996
            annual  compensation  was estimated and was projected to increase at
            3% per year.  Corporate  profitability  was assumed to be "B" level,
            resulting  in 2%  accruals  per year.  Continuous  employment  until
            retirement at age 65 was assumed.  (For anyone  already over age 65,
            the April 1, 1996 age was  used.)  These  assumptions  and data will
            remain  fixed;  they will not be  adjusted in later years to reflect
            actual corporate  profitability rates,  employment  experiences,  or
            changes in other assumptions used to calculate the benefit under the
            Retirement  Programs.  The result of this  calculation is called the
            "Old Plan Benefit."

            2) The value of the Old Plan  benefit  was  converted  to a lump sum
            payable  at age 65 using a  discount  rate of 9% and the 1983  Group
            Annuity Mortality Table (50% male, 50% female).  (For any individual
            not a participant  in the  Retirement  Program as of March 31, 1996,
            the Old Plan Benefit is zero.)

            3)  The  account  balance  that  will  be  provided  by  the  3%  of
            Compensation  contribution  in item A above was projected to the end
            of the year  prior to age 65,  assuming  accruals  start  January 1,
            1996, with an assumed  contribution date at the end of each calendar
            year while the  Participant is under age 65, and an assumed  account
            earnings  rate of 9% per year.  This total amount is called the "New
            Plan Benefit."

            4) The New Plan Benefit  (calculated  in Item 3 above) is subtracted
            from  two-thirds  of the  lump sum  value  of the Old  Plan  Benefit
            (calculated  in  item  2  above).   The  difference  is  called  the
            "Transition Benefit."

            5) If the Transition Benefit (calculated in item 4 above) is zero or
            less,  no additional  contribution  will be added to the amount in A
            above for 1996 or any later year.

            6) If the  Transition  Benefit  (calculated in item 4 above) is more
            than zero, the current value of the Transition Benefit is calculated
            by discounting  the value the Transition  Benefit at age 65 to April
            1, 1996, at 9% interest. This result is called the "Current Value of
            the Transition Benefit."

            7) The Current Value of the  Transition  Benefit was converted to an
            increasing  annuity payable  annually for a number of years equal to
            65 minus the  Participant's  age as of the most  recent  birthday on
            April 1, 1996, assuming 3% annual

                                     V-2





            compensation  increases and 9% annual asset growth. That annuity was
            converted to a percentage of pay ("Transition  Benefit  Percentage")
            by  dividing  the  annual  1996  payment by  estimated  1996 pay and
            rounding to one decimal place.

            8)  Participants  with a Transition  Benefit  Percentage  of 1.0% or
            greater  will receive the  transition  benefit for 1996,  1997,  and
            later  years,  so long as they remain  employed  and  eligible for a
            benefit under the terms of the Plan governing eligibility to receive
            an allocation.

            9) Participants  with a Transition  Benefit  Percentage of less than
            1.0%  will  receive  the  Current  Value of the  Transition  Benefit
            (calculated  in item 6 above) in 1996 if they  remain  employed  and
            eligible  for a  benefit  for  1996  under  the  terms  of the  Plan
            governing eligibility to receive an allocation,  and will receive no
            transition  benefit  for any year  after  1996  even if they  remain
            employed for future years.

      The purpose of the pension feature  contribution is to help ameliorate the
      effect  of the  freeze  of  the  Retirement  Programs  by  creating  a new
      contribution to the Retirement  Savings Plan equal to not less than 2/3 of
      the  future  benefit  lost due to the freeze of the  Retirement  Programs.
      Therefore,  notwithstanding  the preceding  provisions of this  subsection
      5.1(b), any employee whose compensation  during the period January 1, 1996
      through March 31, 1996 exceeded  $150,000 shall receive no pension feature
      contribution for 1996.

      The contributions  calculated under this subsection 5.1(b) are intended to
      meet the general  test under Code  Section  401(a)(4)  both in 1996 and in
      1997 and later years.

      5.2   Average Contribution Test:

            (a)  ACP:  Subject  to  Paragraph  5.7,  the  average   contribution
      percentage for the Plan Year for Highly  Compensated  Employees  shall not
      exceed the greater of the following average contribution percentage tests:
      (i) the  average  contribution  percentage  for  such  Plan  Year of those
      eligible Employees who are not Highly Compensated  Employees multiplied by
      1.25;  or (ii) the average  contribution  percentage  for the Plan Year of
      those  eligible  Employees  who  are  not  Highly  Compensated   Employees
      multiplied by 2.0, provided that the average  contribution  percentage for
      Highly  Compensated  Employees  does not exceed the  average  contribution
      percentage  for such other  eligible  Employees  by more than 2 percentage
      points. The test in clause (ii) shall not be used if the parallel test was
      used  under  Section  4.5(b)(i),  to  the  extent  such  multiple  use  is
      prohibited  by the Code.  For  purposes  of this  Article V, the  "average
      contribution  percentage" for a Plan Year means,  for each specified group
      of employees,  the average of the ratios  (calculated  separately for each
      Employee  in  such  group)  of  (i)  the  sum  of  (A)  Employer  Matching
      Contributions  described  in Section 5.1 for the Plan Year,  (B) Basic and
      Supplemental  After-Tax  Contributions  for the Plan Year,  and (C) if the
      Committee so elects in accordance with and to the extent  permitted by the
      Regulations,  Basic and Supplemental  Pre-Tax  Contributions,  to (ii) the
      amount of the

                                     V-3





      Participant's  compensation (as defined in Section 414(s) of the Code) for
      the Plan Year.  In accordance  with  regulation  1.401(m)-1(b)(5)  and the
      related  Example 3, for the purpose of passing the ACP test the  Committee
      may elect to treat as Matching  Contributions some or all of the Basic and
      Supplemental  Pre-Tax  Contributions  of  HCEs as  well  as of  NHCEs.  An
      eligible  Employee's average  contribution  percentage shall be zero if no
      contributions are made on his behalf for such Plan Year.

            (b) Refund  (Leveling  Method) or  Forfeiture:  The Committee  shall
      determine as of the end of the Plan Year, and at such time or times in its
      discretion,  whether  one of the  average  contribution  percentage  tests
      specified in  subparagraph  5.2(a) is satisfied  for such Plan Year.  This
      determination  shall be made after  first  determining  the  treatment  of
      excess  deferrals  within the meaning of Section  402(g) of the Code under
      Paragraph 4.2 and then  determining the treatment of excess  contributions
      under  subparagraph  4.5(b).  In the event  that  neither  of the  average
      contribution percentage tests is satisfied,  the Committee shall refund or
      forfeit the excess  contributions  in the manner described in subparagraph
      5.2(d).  For purposes of this Article V, "excess aggregate  contributions"
      means,  with respect to any Plan Year and with respect to any Participant,
      the excess of the aggregate  amount (and any earnings and losses allocable
      thereto before the gap period between the end of the calendar year and the
      date of distribution) of (a) Employer  Matching  Contributions,  (b) Basic
      and   Supplemental   After-Tax   Contributions   and  (c)  the  Basic  and
      Supplemental  Pre-Tax  Contributions  (if the  Regulations  permit and the
      Committee  elects to take into  account  Basic  and  Supplemental  Pre-Tax
      Contributions  when  calculating the average  contribution  percentage) of
      Highly  Compensated  Participants  for such Plan  Year,  over the  maximum
      amount of such Employer  Contributions,  Basic and Supplemental  After-Tax
      Contributions and Basic and Supplemental Pre-Tax  Contributions that could
      be made to the account of Participants  without violating the requirements
      of   subparagraph   5.2(a).   The  amount  of  each   Highly   Compensated
      Participant's  excess  aggregate  contributions  shall  be  determined  by
      reducing the average  contribution  percentage of each Highly  Compensated
      Participant  whose  average  compensation  percentage  is in excess of the
      percentage  otherwise  permitted under subparagraph  5.2(a) to the maximum
      amount permitted by that paragraph.

            The  reduction  shall be determined  by the leveling  method,  under
      which the actual  contribution  ratio of the Highly  Compensated  Employee
      with the  highest  actual  contribution  ratio is  reduced  to the  extent
      required  to (i) enable the Plan to  satisfy  the ACP test,  or (ii) cause
      such Highly Compensated  Employee's actual contribution ratio to equal the
      ratio of the Highly  Compensated  Employee  with the next  highest  actual
      contribution ratio. This leveling process shall be repeated until the Plan
      satisfies the ACP test. Provided, however, that for years after 1996, if a
      different leveling method is mandated by the Code, such different leveling
      method shall be used instead.

            (c)  Forfeiture  of  Non-vested  Matching  Contributions:   Matching
      contributions that were not forfeited under Section 4.5(b)(iii) may not be
      forfeited  except  to the  extent  that  they are not  vested.  Non-vested
      matching contributions (and any earnings and losses

                                     V-4





      allocated thereto) may be forfeited,  but such forfeited contributions are
      still counted as annual additions under Sections 404 and 415 of the Code.

            (d) Timing of Refund or Forfeiture:  If the Committee is required to
      refund  or  forfeit  excess   aggregate   contributions   for  any  Highly
      Compensated   Participant  for  a  Plan  Year  in  order  to  satisfy  the
      requirement of subparagraph  5.2(a), then the refund or forfeiture of such
      excess aggregate  contributions  shall be made with respect to such Highly
      Compensated  Participants to the extent practicable before the 15th day of
      the third month immediately  following the Plan Year for which such excess
      aggregate  contributions  were made, but in no event later than the end of
      the Plan Year following such Plan Year, or, in the case of the termination
      of the Plan in accordance  with Article XIII, no later than the end of the
      twelve-month  period  immediately  following the date of such termination.
      For each of such  Participants,  amounts so refunded or forfeited shall be
      made in the following  order of priority:  (A) to the extent  permitted by
      law, by forfeiting nonvested Employer Matching Contributions, and earnings
      thereon; (B) by distributing vested Employer Matching  Contributions,  and
      earnings thereon, of Highly Compensated Participants;  (C) by distributing
      Supplemental or Basic After-Tax  Contributions,  and earnings thereon; and
      (D) by distributing  Supplemental or Basic Pre-Tax  Contributions  (to the
      extent such amounts are included in the average  contribution  percentage)
      and earnings thereon. All such distributions and forfeitures shall be made
      to or be with respect to Highly  Compensated  Participants on the basis of
      the respective  portions of such amounts  attributable to each such Highly
      Compensated  Participant.  The amount of any forfeitures  made pursuant to
      this Paragraph 5.2 shall be used to reduce Employer Matching Contributions
      in accordance with Paragraph 5.4.


            (e)  Family  Aggregation  Rules:  Only  to the  extent  that  family
      aggregation  rules  are  mandated  by  the  Code,  if an  eligible  Highly
      Compensated Employee is subject to the family aggregation rules or Section
      414(q)(6) of the Code because such employee is either a five-percent owner
      or one of the ten most Highly Compensated  Employees,  the combined actual
      contribution  ratio for the family  group  (which is treated as one Highly
      Compensated  Employee)  shall be  determined  by  combining  the Basic and
      Supplemental  After-Tax  Contributions and Employer Matching Contributions
      of all the eligible family members.

            The Basic and Supplemental After-Tax Contributions, Compensation and
      amounts treated as Employer  Matching  Contributions of all family members
      shall be disregarded for purposes of determining  the actual  contribution
      percentage for the group of Highly Compensated Employees, and the group of
      eligible Employees.

            If an Employee is required to be aggregated as a member of more than
      one family  group in a plan,  all  eligible  Employees  who are members of
      those family groups that include that Employee  shall be aggregated as one
      family group.

            (f)  The   determination   and   correction   of  excess   aggregate
      contributions of a Highly Compensated  Employee whose actual  contribution
      ratio is  determined  under the family  aggregation  rules of (e) shall be
      accomplished as follows: the actual contribution ratio shall be reduced as
      required under subparagraph 5.2(b) and the excess aggregate

                                     V-5





      contributions  for the  family  unit shall be  allocated  among the family
      members   in   proportion   to  the  Basic  and   Supplemental   After-Tax
      Contributions  and Employer  Matching  Contributions of each family member
      that are combined to determine the actual contribution ratio.

      5.3   Remittance   of  Employer   Contributions   to   Trustee:   Employer
Contributions, if any, shall be made solely in cash and shall be remitted to the
Trustee,  as  soon as  practicable  after  the end of the  year  for  which  the
Company's  Profitability Level was attained;  provided,  however,  that Employer
Contributions  to the NL Stock Fund, may be made in shares of Common Stock of NL
or in cash.

      5.4   Allocation of Employer Contributions and Forfeitures:

            (a) General: All Employer Contributions shall be used by the Trustee
      to make purchases for the Investment  Fund or Funds in accordance with the
      respective  investment  elections of the  Participant to whose account the
      Employer Contributions are allocated.  All Employer Contributions shall be
      allocated to the accounts  established  in accordance  with Article VII of
      each Participant entitled to share in such contributions.

            (b) December 31 Rule: Employer Pension Feature Contributions accrued
      on  behalf  of a  Participant  shall be  allocated  to such  Participant's
      account whether or not such  Participant  remains employed on the last day
      of the Plan Year.  Notwithstanding  any other  provision  of the Plan,  no
      Employer Matching  Contributions  shall be made for the benefit of, and no
      Employer Matching  Contributions or forfeitures shall be allocated,  added
      or otherwise  credited to the account of, a Participant under the Plan who
      was not an  Employee  of an  Employer  on the last  day of the Plan  Year;
      provided,  however,  a Participant who terminated  Service during any Plan
      Year on his Retirement Date or by reason of his death or Disability  shall
      be treated as if he was an active Participant on the last day of such Plan
      Year.  In addition,  any  Participant  who is, on the last day of the Plan
      Year on a leave of absence to which such  Employee is  entitled  under the
      Family and Medical Leave Act of 1993 ("FMLA") shall be deemed to be in the
      employ of the  Employer on such last day unless final  regulations  issued
      under the FMLA do not require such treatment for this purpose.

            (c) Use of  forfeitures:  Amounts in the  accounts  of  Participants
      which are  forfeited in accordance  with Article VIII and  Paragraph  16.6
      shall be  applied  during  the  continuance  of the Plan in the  following
      order: (i) to restore the accounts of reemployed  participants pursuant to
      subparagraph  8.4(b),  (ii) to restore  the  accounts of  Participants  or
      Beneficiaries who apply for forfeited  benefits pursuant to Paragraph 16.6
      and (iii) to reduce the amount of Employer Contributions otherwise payable
      by their Employer. If upon complete  discontinuance of contributions under
      the Plan or termination of the Plan any such  forfeitures have not been so
      applied,  such  unapplied  amount shall be allocated  among all  remaining
      Employees who are Participants in accordance with Paragraph 13.2.

                                     V-6





      5.5 Investment and  Administrative  Expenses:  All brokerage  commissions,
taxes and other expenses related to the purchase and sale of securities shall be
paid out of the assets of the Trust  Fund,  as directed  by the  Committee.  All
other expenses,  including any taxes which may be imposed upon the Trust Fund or
upon the income therefrom,  compensation of the Trustee,  investment  management
fees,  fees for legal and  accounting  purposes and all other costs and expenses
incurred in administering the Plan,  unless paid by the Employer,  shall be paid
out of the Trust Fund, as directed by the Committee.

      5.6   Multiple Use:

            (a)  Notwithstanding  any other  provision  under this Plan,  in the
      event there is multiple use, as defined and determined in accordance  with
      Section  1.401(m)-2  of  the  Regulations,  such  multiple  use  shall  be
      corrected to the extent required by the Regulations by reducing the actual
      contribution  percentage,  as defined in  subparagraph  5.2(a),  of Highly
      Compensated Employees in the manner prescribed in subparagraph 5.6(b).

            (b)  The  amount  of  the  reduction  to  the  actual   contribution
      percentage  of Highly  Compensated  Employees  shall be  calculated in the
      manner described in subparagraph  5.2(b) so that there is no multiple use.
      The reduction shall be treated as an excess aggregate contribution.

      5.7 Qualified Non-Elective Contributions:  At the election of the Board of
the  Plan  Sponsor,  in lieu of  distributing  excess  contributions  to  Highly
Compensated Employees in order to satisfy the actual deferral percentage test or
the  actual  contribution  percentage  test,  the  Employer  may make  Qualified
Non-Elective  Contributions  on  behalf  of one or more  non-Highly  Compensated
Employees who are  Participants in such amounts as are sufficient to satisfy the
actual deferral percentage test or the actual contribution percentage test.

                                     V-7





                                  ARTICLE VI

                          INVESTMENT OF CONTRIBUTIONS



      6.1  Investment   Funds:  Each  Participant  at  the  time  he  becomes  a
Participant  under the Plan shall submit written  instructions  to the Committee
(unless the Committee  establishes a different way to submit such  instructions)
to  invest  any and all  contributions  made by him or on his  behalf  in  whole
percentages  in any one or a combination  of Investment  Funds (which conform to
any portfolio  standards and  guidelines  established  by the Trustee) as may be
determined  from time to time by the  Committee  and made  available on an equal
basis to all individuals  with accounts in the Plan. The Investment  Funds shall
include at least the following  five,  but may include  additional  funds at the
Committee's discretion:


            (a)  Money  Market  Fund:  an  income  producing   diversified  fund
      comprised of short-term money market  instruments that seeks to maintain a
      constant $1 per share value.  Acceptable  securities include,  but are not
      limited  to,  U.S.  Government  and U.S.  Government  Agency  obligations,
      commercial  paper,  time  deposits,  certificates  of deposit,  Eurodollar
      deposits,  repurchase  agreements,  banker's  acceptances  and  guaranteed
      investment contracts.

            (b) Fixed  Income  Fund:  a  diversified  fund that may  invest in a
      variety of short-,  intermediate-  or long-term fixed income  instruments,
      that may seek a mixture of capital  gains and current  income.  Acceptable
      securities  include,  but are not  limited to,  U.S.  Government  and U.S.
      Government Agency obligations, corporate bonds and notes and mortgage- and
      asset-backed  securities  and other  money  market  instruments.  The fund
      assumes a higher  degree of risk  than a money  market  fund and its share
      value may fluctuate considerably.

            (c) Equity Fund: a diversified fund that invests primarily in equity
      securities  traded in public  markets in the U.S.  or in foreign  markets,
      that seeks growth in asset value and possibly  current income.  The fund's
      investments  can be  comprised  of  common  stock  from a  wide  array  of
      companies and industries.  The fund will typically  assume a higher degree
      of risk  than a money  market  fund and a fixed  income  fund but may also
      achieve a higher long term rate of return.  The fund's  share value can be
      expected to fluctuate considerably.

            (d) NL Stock Fund: A fund invested  primarily in Common  Stock.  All
      dividends  declared  and paid on Common  Stock held in the NL Stock  Fund,
      shall  be  used,  as soon  as  practicable,  by the  Trustee  to  purchase
      additional  Common  Stock,  the value of which shall be  allocated to such
      Participant's account.


                                     VI-1





            (e) The  Dresser/Tremont  Stock Fund: A fund which shall hold shares
      of Common Stock which were received by the Trustee as a result of the Plan
      of Restructuring of NL Industries,  Inc.,  approved by the shareholders of
      the Company at the special  meeting held on December  22, 1988,  and which
      Participants  elected to retain in the form of Baroid  Corporation  Common
      Stock in lieu of exchanging it for Common Stock of the Company (the Baroid
      Corporation common stock having later been acquired by Dresser Industries,
      Inc.),   and  shares  of  Common  Stock  of  Tremont   Corporation   which
      Participants  received  due to the  subsequent  reorganization  of  Baroid
      Corporation into Tremont Corporation and Baroid Corporation. No additional
      contributions  or  transfers  to the  Dresser/Tremont  Stock  Fund will be
      permitted.  Dividends paid on the securities in the Dresser/Tremont  Stock
      Fund  will be  allocated  to the  respective  Participant's  accounts  and
      invested in accordance  with the  Participant's  most recent  instructions
      directing the  investment of new  contributions  to the Plan. No shares of
      Dresser or Tremont  Common Stock will be purchased on or after  January 1,
      1994.

      6.2  Temporary  Investments:  After the  allocation of assets of the Trust
Fund  to any of the  Investment  Funds,  but  prior  to  investment  or  pending
reinvestment of monies in securities of a type consistent with the objectives of
any such Fund,  the Trustee or  Investment  Manager may  temporarily  invest and
reinvest  any such  assets in  securities  with  maturities  of one year or less
issued or guaranteed by the Government of the United States of America or by any
agency or instrumentality  thereof, or in the name of the Trustee in any savings
accounts or  certificates of deposit in any banks, or may maintain cash balances
consistent with the liquidity needs of the Plan.

      6.3 Change in Investment Election for Future Contributions: Any investment
election filed by a Participant  for investment of current  contributions  shall
continue in effect until changed by the  Participant.  A Participant  may change
his current investment  election as to future  contributions.  Effective July 1,
1990,   changes  in  investment   elections  may  be  made  by  telephoning  the
representative  of the  Trustee  at  the  number  stated  in  the  summary  plan
description of the Plan, and following the instructions of that  representative.
Written  confirmation of the transaction  will be sent to the Participant by the
Trustee  and  such  written  confirmation  is  binding  unless  the  Participant
demonstrates  an error in such  written  confirmation  within the number of days
stated on the written confirmation.

      6.4  Inter-Fund  Transfers:  Effective  July 1, 1990,  a  Participant  may
transfer all or any portion of his account balance in any Fund (in increments of
1%) to any other Fund upon submission to the investment  manager appointed under
Section 11.2 the appropriate  information in the form required by the investment
manager under uniform procedures.

      Transfers may be made as often as daily. Instructions must be received one
business  day in  advance of the  business  day on which the  transfer  is to be
effected.  A business day is a period of time during a calendar day when the New
York financial markets are open.


                                     VI-2





      Notwithstanding the preceding  paragraph,  only one transfer per month may
affect a  Participant's  accounts in the NL Stock Fund, and only one transfer is
permitted out of a  Participant's  Dresser/Tremont  Stock Fund. No transfer into
the Dresser/Tremont Stock Fund will be permitted. Transfers under this paragraph
are permitted any business day of the quarter  requested by the Participant with
one  business day advance  notice,  and  settlement  will take place within five
business days. Any commissions charged will be paid by the forfeiture account of
the Plan or by the Employer.

      6.5 Suspension of Investments  and Investment  Transfers into the NL Stock
Fund or the  Dresser/Tremont  Stock  Fund:  Notwithstanding  any  election  by a
Participant,  during  any  period  of time  when  (a) a  Registration  Statement
covering the Plan is not in effect,  (b) although in effect,  information in the
Prospectus  forming  part of such  Registration  Statement  does  not  meet  the
requirements of the Securities Act of 1933, as amended,  or is not available for
delivery,  or (c) in the judgment of the Company, a proceeding by the Securities
and  Exchange  Commission  for  the  issuance  of a stop  order  suspending  the
effectiveness  of the Registration  Statement is threatened or contemplated,  no
future Basic, Supplemental, or Employer Contributions may be invested in, and no
such prior  contributions,  or income earned  thereon,  may be  transferred  for
investment  in the NL Stock  Fund or the  Dresser/Tremont  Stock  Fund.  In lieu
thereof,  the Trustee  shall  invest such amounts in short term  investments  in
accordance  with  Paragraph  6.2. At such time as (a) a  Registration  Statement
covering the plan shall become  effective,  (b) the  Prospectus  forming part of
such Registration  Statement shall have been amended to meet the requirements of
the Act or shall be available  for  delivery,  or (c) no stop order  proceedings
shall be threatened or contemplated, such amount shall be invested as previously
directed,  until such prior  direction is changed in accordance  with  Paragraph
6.3.

      6.6 Proxy Material for Those  Participants for Whom an Investment Has Been
Made in the NL Stock Fund or the Dresser/Tremont  Stock Fund: Before each annual
or special  shareholders'  meeting of the applicable company,  the Trustee shall
furnish  to  each  Participant  with  an  account  in the NL  Stock  Fund or the
Dresser/Tremont Stock Fund, a copy of the proxy solicitation material,  together
with a form  requesting  confidential  instructions  to the  Trustee on how such
Common Stock (including fractional shares, to 1/10th of a share) is to be voted.
Such proxy  solicitation  material will be furnished to participants in a timely
manner so as to comply with  applicable  federal and/or state laws.  Upon timely
receipt  of such  instructions,  the  Trustee  shall vote such  Common  Stock as
instructed.  The instructions received by the Trustee from Participants shall be
held by the Trustee in strict  confidence  and shall not be divulged or released
to any person  including  officers or employees of the Company or any Affiliated
Company.  The Trustee shall not make  recommendations to Participants on whether
to vote or how to vote. If voting instructions for Common Stock for a particular
shareholders  meeting are not timely  received  from  Participants,  the Trustee
shall not vote such Common  Stock,  except that  effective  January 1, 1994,  if
timely  instructions  are not  received  from  Participants,  or if the  Trustee
determines that the instructions  received violate ERISA, the trustee shall vote
such Common  Stock for which  valid  instructions  are not  received in the same
proportion as are voted the shares for which valid instructions are received.


                                     VI-3





      6.7 Exercise of Tender Rights:  Each Participant shall have the right from
time to time with respect to the shares of Common Stock allocated to his account
in the NL Stock Fund or the  Dresser/Tremont  Stock Fund to instruct the Trustee
in writing as to the manner in which to respond to any tender or exchange offers
which shall be pending or which may be made in the future for all such shares of
Common Stock or any portion thereof.  A Participant's  instructions shall remain
in force until  superseded  in writing by the  Participant.  The  Trustee  shall
tender  or  exchange  such  shares  of  Common  Stock  as and to the  extent  so
instructed.  If the Trustee  shall not receive  instructions  from a Participant
regarding  tender or exchange offers for Common Stock, the Trustee shall have no
discretion in such matter and shall take no action in response  thereto.  Unless
and until  shares of Common  Stock are  tendered or  exchanged,  the  individual
instructions  received by the  Trustee  from  Participants  shall be held by the
Trustee  in strict  confidence  and shall not be  divulged  or  released  to any
person,  including  officers  or  employees  of the  Company  or any  Affiliated
Company;  provided,  however,  that the Trustee shall advise the Company, at any
time upon  request,  of the total  number of shares of Common Stock which it has
been  instructed  to tender or exchange  and the total number of such shares not
subject to  instructions  to tender or exchange.  The Trustee  shall notify each
Participant  of each  tender or exchange  offer and utilize its best  efforts to
timely distribute or cause to be distributed to such Participant all information
distributed to shareholders of the Company in connection with any such tender or
exchange offer.

      6.8 Best  Interests  of  Participants:  In the event that the Trustee or a
court of  competent  jurisdiction  determines  that the  Trustee  shall have the
discretion or power to sell,  convey or transfer any shares of Common Stock held
in the NL Stock  Fund or the  Dresser  Tremont  Stock  Fund of the Trust Fund in
response  to a tender or  exchange  offer,  notwithstanding  the  provisions  of
Section 6.7, the Trustee in exercising such discretion or power shall be obliged
to consider not only any increased value in the accounts of the  Participants in
the NL Stock  Fund or the  Dresser  Tremont  Stock  Fund of the Trust  Fund as a
result of a tender or exchange of the shares of Common  Stock in the accounts of
such  Participants,  but also the  impact  of any  change in the  management  or
control of the Company on the status of the  Participants  as  employees  of the
Company  in the  long  run,  not  over a  short  period,  such as  whether  such
Participants will be retained or dismissed as employees of the Company,  whether
such  Participants  will receive  greater or fewer benefits than they receive as
employees of the Company at present,  including coverage under pension,  savings
or thrift,  or employee stock  ownership  plans similar to the Company's  plans,
whether  such  plans are as well  funded as the  Company's  plans,  whether  the
Participants  will receiver  greater or lower levels of compensation and whether
the  Participants  will continue to be covered by a savings or thrift plan, such
as the Plan.  To the maximum  extent  permitted  by law,  the  Trustee  shall be
obliged  to  treat  the   instructions  of  Participants  who  have  given  such
instructions as indicative of whether  tendering shares of Common Stock would be
in the best interests of other Participants.

      6.9 Assumption of Investment Risk by Participants:  Upon the withdrawal or
distribution  of benefits under the Plan, a Participant  or  Beneficiary  may be
entitled  to  receive  shares  of  Common  Stock or cash as  provided  for under
Articles IX and X. The Employer does not guarantee that the current market value
of Common  Stock or any other  investment  will be equal to the  purchase  price
thereof or that the total amount  withdrawn or distributed in cash will be equal
to or greater than the

                                     VI-4





amount  of  the  Participant's   Basic  or  Supplemental   Contributions.   Each
Participant  assumes  all risks in  connection  with any  decrease in the market
price of any common stocks or other  investments or Investment Funds held on his
behalf in accordance with the provisions of the Plan.

      If a Participant or Employee  submits invalid  instructions  directing the
investment  of his  account,  his  account  shall  continue  to be  invested  in
accordance with the most recent valid instructions  received by the Committee or
in  accordance  with  Section  6.3.  If no valid  instructions  have  ever  been
received, such Participant or Employee shall be deemed to have elected to invest
his account in the Money Market Fund, or if none is offered, the Investment Fund
that the  Committee  determines to be closest to a money market fund in expected
risk.

      6.10 Section 404(c) of ERISA: Except as may otherwise be prescribed by the
Committee, categories of assets, election procedures and other rules relating to
investment  elections  shall comply with the  requirements  of Section 404(c) of
ERISA.

                                  ARTICLE VII

                TRUST FUND ACCOUNTS AND ALLOCATION OF EARNINGS

      7.1 Participant's  Account:  The Committee shall cause to be maintained in
an equitable manner a separate account for each Participant in which there shall
be kept a separate  record of the share of such  Participant in each  Investment
Fund of the Trust  Fund  which is  attributable  to his  Basic and  Supplemental
After-Tax  and Pre-Tax  Contributions,  Roll-over  Contributions,  if any,  made
pursuant to Article IV hereof and the Employer Contributions made on his behalf.

      7.2 Valuation of Investment  Funds:  The Committee shall cause the Trustee
to value  separately  the  Investment  Funds  described in Article VI as of each
Valuation Date by  determining  the fair market value of the Trust Fund's assets
then held in each of the Investment Funds.

      7.3 Valuation of Accounts:  The difference  between the value of each such
Investment  Fund on any  Valuation  Date and its value as of the last  preceding
Valuation  Date  together with  interest,  dividends and other sums received and
accrued but not yet invested,  less expenses,  shall be credited or debited,  as
the case may be,  to the  account  balances  of the  Participants  in each  such
Investment Fund.

      7.4 Statement of Participant's  Account:  As soon as practicable after the
completion of a Plan Year, an individual statement of account shall be issued to
each Participant showing the value of his interest in each Fund.



                                    VII-1





                                 ARTICLE VIII

                                    VESTING

      8.1 Vesting With Respect to Predecessor  Plan  Contributions,  Participant
Contributions  and  Pre-Tax  Contributions  Made  After  December  31,  1973:  A
Participant  shall at all  times be fully  vested in the  current  value of that
portion  of  his  account  which  is   attributed  to  Basic  and   Supplemental
Contributions, Rollover Contributions, Direct Rollovers, and direct transfers to
the Trust Fund (as described in subparagraph 4.10(c)).

      8.2 Vesting With Respect to Employer  Contributions:  A Participant  shall
have no vested interest with respect to the value of that portion of his account
which is  attributed  to  Employer  Contributions,  unless  he shall  have  been
credited  with at least three years of Vesting  Service (as defined in Paragraph
8.3).  If a  Participant  has been credited with at least three years of Vesting
Service,  he shall be vested in 50% of the value of all Employer  Contributions.
If a Participant has been credited with at least four years of Vesting  Service,
he  shall  be  vested  in 75% of the  value  of all  Employer  Contributions.  A
Participant  who has been credited  with at least five years of Vesting  Service
shall be vested in 100% of the value of all Employer Contributions.

      8.3 Years of Vesting Service: Subject to the last sentence of subparagraph
10.1(c), an Employee shall be credited with one year of Vesting Service for each
Plan Year or part thereof  following his  commencement  of  employment  with the
Employer or with an Affiliated  Company during which he shall have been credited
with at least 1,000 Hours of Service or six Months of Service. For this purpose,
an Employee  shall receive credit for all Hours of Service and Months of Service
with an Employer or an  Affiliated  Company,  whether or not such  Employee  was
eligible to participate in the Plan during each such Plan Year. In addition, any
Employee may be credited  with up to five years of employment  with Valhi,  Inc,
Tremont Corporation, Louisiana Pigment Company, L.P., or Baroid Corporation (but
only if such employment with Baroid Corporation preceded Baroid's acquisition by
or merger with Dresser  Industries,  Inc.) prior to such Employee's date of hire
by the  Employer.  Notwithstanding  the fact that a  Participant  has incurred a
forfeiture  under the rules described in Paragraph 8.4, years of Vesting Service
shall  include  years of Vesting  Service  prior to a one-year  Break in Service
subject to the following rules:

            (a) If a vested  Participant  has a one-year  Break in Service,  his
      pre-break and  post-break  service  shall be used for  computing  years of
      Vesting Service upon his date of reemployment.

            (b)  After  five   consecutive   one-year   Breaks  in  Service,   a
      Participant's  vested interest in the value of his Employer  Contributions
      attributable  to pre-break  service  shall not be increased as a result of
      post-break service.

      8.4  Forfeitures  Upon  Distribution  Prior to Full Vesting and Repayment:
Except as provided in Paragraphs 8.5 and 8.6, any termination of employment of a
Participant, prior to the time

                                    VIII-1





his account attributable to the Employer  Contributions made with respect to him
is 100%  vested  in  accordance  with  Paragraphs  8.2 or 8.5,  may  result in a
forfeiture  of  the  current  value  of the  nonvested  amounts  subject  to the
following provisions, effective January 1, 1992.

            (a) General Rule: The value of his vested  interest in his Basic and
      Supplemental  After-Tax  Contributions,  and in the Basic and Supplemental
      Pre-Tax  Contributions and Employer  Contributions made on his behalf will
      be paid to him in accordance with Paragraph 9.1. Notwithstanding any other
      provisions  of the Plan to the contrary,  any nonvested  amounts that were
      held under the Plan (as in effect  immediately prior to the Plan Year that
      commenced on January 1, 1992), in Accounts maintained for Participants who
      had incurred at least five (5)  consecutive  one year Breaks in Service on
      or before January 1, 1992,  shall be deemed to have been forfeited  during
      the first Plan Year that commenced immediately after December 31, 1991 and
      shall be applied as herein provided.

            (b) Cashouts Within Two Plan Years After Employment Terminates:  The
      Participant shall not be entitled to the value of the nonvested portion of
      his account attributable to Employer Contributions which nonvested portion
      shall be  forfeited  as of the date  distribution  of his  vested  account
      balance  is  made  or  commenced  (due  to  such  person's   cessation  of
      participation  in the Plan) by the close of the second  complete Plan Year
      following the Plan Year in which his employment terminated, and applied in
      accordance  with Paragraph 5.4.  Otherwise,  with respect to the nonvested
      portion of such account of a Participant  who received a  distribution  of
      all or a portion of the vested  portion of such account  other than by the
      close of the second  complete  Plan Year  following the Plan Year in which
      his  employment  terminated,  such  forfeiture  shall occur on the date on
      which such Participant incurs five consecutive  one-year Breaks in Service
      following the date of termination of employment.  Provided,  however, that
      if the  Participant  (1) received a  distribution  which includes the full
      amount of his  entire  vested  interest  in his  account  attributable  to
      Employer  Contributions as a result of his termination of participation in
      the Plan, which distribution is $3,500 or less, or is more than $3,500 but
      is consented to, (2) returns to active  employment  before  incurring five
      consecutive  one-year  Breaks in Service and (3) not later than the end of
      the  five-year  period   beginning  with  the  Employee's   resumption  of
      employment  covered  by the Plan,  repays to the  Trust  Fund,  in cash or
      shares of  Employer  Stock (but only to the extent of the number of shares
      received upon  distribution),  the entire value of his account  balance at
      the time of  distribution  to him,  the amount  repaid  and the  nonvested
      portion of the Employer Contributions previously made on the Participant's
      behalf shall be restored to such Participant's accounts in an amount equal
      to the  value of his  accounts  on the date of  distribution  and shall be
      invested in accordance  with the option in effect for such  Participant at
      the time of repayment.  In addition,  if such  Participant  (1) received a
      distribution  by the close of the second Plan Year following the Plan Year
      in which his employment  terminated,  which distribution was less than the
      full amount of his entire vested  interest in his account  attributable to
      Employer Contributions,  which interest is $3,500 or less, or is more than
      $3,500 but is consented  to, and (2) returns to active  employment  before
      incurring five consecutive one-year Breaks in Service following the date

                                    VIII-2





      his  employment   terminated,   the  nonvested  portion  of  the  Employer
      Contributions  previously  made  on  the  Participant's  behalf  shall  be
      restored to such Participant's accounts in an amount equal to the value of
      his  accounts  on  the  date  the  distribution   commenced   without  any
      requirement that he repay to the Trust Fund any amount of the distribution
      attributable  to Employer  Contributions;  provided,  however,  any future
      distributions  attributable to Employer  Contribution  shall be subject to
      offset  by the  amount  of the  prior  distribution  that  was not  repaid
      incident to  restoration  to the  Participant's  account  pursuant to this
      sentence.  There shall be no adjustment  for any gains or losses which may
      be incurred between the date of distribution and the date of repayment.

            (c)  Deemed  Cashouts:  If the  Participant  did not  have a  vested
      interest in any  contributions  credited to his account at the time of his
      termination  of  participation  in the  Plan he shall  be  deemed  to have
      received  distribution of a vested interest in any contributions  credited
      to his account equal to zero (although  actually receiving no distribution
      from his account as a result of his  termination of  participation  in the
      Plan), and his account will be restored if he resumes  employment  covered
      under the Plan prior to  incurring a period of five  consecutive  one-year
      Breaks in Service following the date of the termination.

            (d)  Distribution  Made or Begun  More  Than Two  Plan  Years  After
      Employment Terminates: With respect to a Participant whose vested interest
      in his account  attributable to Employer  Contributions  is less than 100%
      and who receives a termination  distribution from his account attributable
      to Employer  Contributions other than by the close of the second Plan Year
      following  the Plan Year in which his  employment  terminated,  any amount
      remaining  in his account  attributable  to Employer  Contributions  shall
      continue to be maintained  as a separate  account.  At any relevant  time,
      such Participant's  nonforfeitable  portion of such separate account shall
      be determined in accordance with the following formula:

                               X = P(AB + D) - D

      For purposes of applying the formula: X is the  nonforfeitable  portion of
      such separate account at the relevant time; P is the Participant's  vested
      interest in his account  attributable  to  Employer  Contributions  at the
      relevant time; AB is the balance of such separate  account at the relevant
      time; and D is the amount of the  distribution.  For all other purposes of
      the Plan, a Participant's  separate account shall be treated as an account
      attributable to Employer  Contributions.  The forfeitable  portion of such
      terminated  Participant's  separate account shall be forfeited on the date
      on which such  Participant  incurs  five  consecutive  one-year  Breaks in
      Service following the date of termination of employment.

            (e) Deferred Vested Distributions: With respect to a Participant who
      terminates  employment  with the  Employer  with a vested  interest in his
      account  attributable to Employer  Contributions  greater than 0% but less
      than 100% and who is not otherwise subject to the forfeiture provisions of
      paragraph (b) or paragraph (d) above, the forfeitable portion of such

                                    VIII-3





      terminated  Participant's  account attributable to Employer  Contributions
      shall be  forfeited  on the date on which  such  Participant  incurs  five
      consecutive  one-year Breaks in Service  following the date of termination
      of employment.

            (f)  Investment  of  Forfeitable  Account  Balances:   A  terminated
      Participant  shall be entitled to direct the  investment of his Account up
      until  such  time  as  investments  are  liquidated,  if  applicable,  and
      distribution  of his entire  vested  interest is made in  accordance  with
      Article IX. Thereafter,  the forfeitable  portion of such Account shall be
      invested by the Committee.

      8.5 Full  Vesting:  Notwithstanding  the  provisions  of Paragraph  8.2, a
Participant  shall  be  fully  vested  in  all  Employer  Contributions  if  his
employment is terminated as a result of his  Retirement,  Disability or death. A
Participant  shall also be fully vested upon attainment of his normal retirement
age  regardless  of whether he  actually  retires on such date,  except that for
Participants  first  hired  by an  Employer  on or  after  January  1,  1997,  a
Participant shall be fully vested upon attainment of the later of (i) his normal
retirement age (regardless of whether he actually retires on such date) and (ii)
the completion of five years of Vesting  Service.  For purposes of the preceding
sentence,  a Participant's  normal retirement age shall be the earlier of age 65
or the age  treated as his normal  retirement  age under the  provisions  of any
formal retirement plan the Company under which he may be covered.

      8.6  Other   Provisions   Affecting   Vesting:   If  the   termination  of
participation  of any  Participant is occasioned by a change in ownership of the
outstanding  stock  of an  Affiliated  Company  by  which  such  Participant  is
employed,  or if the  termination of employment of any Participant is occasioned
by  the  sale  or  other  transfer  to  an  acquiring   corporation  of  all  or
substantially  all of the  assets  used by the  Company  in a  division,  plant,
location, or other identifiable unit of the Company by which such Participant is
employed, and if such former Affiliated Company or acquiring corporation, either
prior to or within 60 days from the date of such  change,  evidences  in writing
its intention to continue in effect for its employees a profit  sharing,  thrift
or savings plan for their benefit in accordance  with the terms of the Plan, the
Committee  upon  approval by the Board  shall  direct the Trustee to transfer to
itself, or to such other trustee as such former Affiliated  Company or acquiring
corporation  shall  designate  in a  trust  agreement  containing  the  same  or
substantially  similar  terms and  provisions  as are contained in the agreement
establishing  the Trust  forming part of the Plan,  such assets then held by the
Trustee for such Participant,  without reduction for the nonvested  amounts,  if
any, of his account balance, as the Committee shall determine and certify to the
Trustee, constitute the appropriate share of the Trust Fund then held in respect
of such former Affiliated  Company's or the acquiring  corporation's  employees,
who, prior to the change in ownership, participated under the Plan.


                                    VIII-4





                                  ARTICLE IX

                DISTRIBUTION OF BENEFITS OTHER THAN WITHDRAWALS

      9.1 Normal Form of Payment: Subject to Paragraphs 5.2, 8.6, 13.2, 17.2 and
17.3, distributions shall be made under the Plan only upon the occurrence of one
of the events  described in Paragraph 10.3. In addition,  to the extent required
by  Section  401(k)  of the  Code and  Regulations  or  other  authority  issued
thereunder  by  the  appropriate  governmental  authority,  the  limits  of  the
immediately  preceding  sentence  shall  continue  to apply even if Trust  Funds
attributable  to any  Participant's  account  are  transferred  to another  plan
pursuant to  applicable  provisions  of Paragraph  4.12(c) or 17.3.  Neither the
Committee,  Trustee nor any  Employer  shall have any duty to ensure  compliance
with the  requirements of the immediately  preceding  sentence after the initial
transfer therein described.

      Unless a Participant  otherwise elects, in the case of a Participant whose
employment is terminated  for any reason,  including  Retirement,  the Committee
shall value his account balance as of the Valuation Date coincident with or next
following the date on which such  termination of employment  occurs (or would be
deemed to have occurred).

            (a) If a  Participant's  termination of employment is for any reason
      other than death, all vested amounts then credited to his account shall be
      distributed  in one  lump-sum  payment;  provided,  however,  that no such
      lump-sum  payment  shall  be  made  without  the  written  consent  of the
      Participant where the portion of the payment  attributable to (i) Employer
      Contributions,  (ii)  Basic  and  Supplemental  Contributions,  and  (iii)
      Rollover  Contributions,  exceeds  $3,500.  Such written  consent shall be
      obtained by the Committee within the 90 day period  commencing  before the
      date the  lump-sum  payment  is to be made to the  Participant.  If such a
      Participant  does not  provide  the  Committee  with the  written  consent
      described  above,  the  Participant  shall be  deemed  to have  elected  a
      deferred distribution and all amounts credited to his account at that time
      shall  remain  in the  Investment  Funds,  subject  to his  right  to make
      inter-fund  transfers  pursuant to Paragraph 6.4,  until such  Participant
      either (i) dies (ii)  attains  age 65 or (iii)  consents  in writing to an
      earlier date for distribution;  provided,  however,  if any Participant or
      Beneficiary  elects a deferred  lump-sum  payment  described in Paragraphs
      9.2(b), such amounts credited to the Participant's account shall remain in
      said  Investment  Funds,  subject  to  inter-fund  transfers  pursuant  to
      Paragraph 6.4, until the Valuation Date  designated by the  Participant or
      the  Beneficiary for  distribution  of benefits,  with payment to occur as
      soon as practicable  thereafter.  If such  Participant dies or attains age
      65,  without  having made a timely  election to defer  distribution  under
      Paragraph  9.2, all amounts  credited to his account at that time shall be
      distributed pursuant to this subparagraph no later than the 60th day after
      the close of the Plan Year in which such  Participant  dies or attains age
      65. Such  Participant's  account balance shall be valued for  distribution
      purposes as of the Valuation Date either (i) designated by the Participant
      for distribution of benefits under this  subparagraph or Paragraph 9.2, or
      (ii)  coincident  with or next following his date of death, as applicable.
      Any such distributions

                                     IX-1





      shall be made as soon as practicable after the applicable  Valuation Date.
      All amounts  distributable  as a lump-sum  under this  Paragraph  9.1 from
      Investment  Funds  other  than the NL Stock  Fund and the  Dresser/Tremont
      Stock Fund shall be paid in cash. Amounts  distributable from the NL Stock
      Fund and the  Dresser/Tremont  Stock Fund shall be paid either entirely in
      cash,  or  entirely  in whole  shares of  Common  Stock and in cash to the
      extent of any fractional  shares (to 1/10th of a share) as the Participant
      shall elect.  Absent such an election,  amounts  distributable from the NL
      Stock  Fund  and the  Dresser/Tremont  Stock  Fund  shall be paid in whole
      shares of Common Stock (and fractional shares to 1/10th of a share paid in
      cash).

            (b) If the value of a Participant's  vested benefit  attributable to
      any Employer  Contributions,  Basic and  Supplemental  Contributions,  and
      Rollover  Contributions,  is less than $3,500,  the  Committee in its sole
      discretion may distribute  such benefit in a cash lump-sum,  regardless of
      any election to the contrary.

      9.2 Alternative  Forms of Payment:  Each Participant  whose vested account
balance  exceeds  $3,500 shall be given,  not less than 30 days nor more than 90
days before the first day of the first  period for which an amount is to be paid
as a partial or complete distribution, a general description of the distribution
options.  After receiving the notice,  a Participant or his Beneficiary may file
with the Committee an election to have his distribution  paid to the Participant
or his  Beneficiary,  as the case may be, in one or more of the forms  described
below in lieu of the immediate  lump-sum payment  provided in Paragraph  9.1(a);
provided,  however, that in the case of termination of employment for any reason
other than death,  Disability or Retirement,  the  Participant may not elect the
annuity form of  distribution  described in  subparagraph  (a) of this Paragraph
9.2. Any such election may be revoked, by the Participant or the Beneficiary, as
the case may be,  at any time  prior to the  commencement  of  benefits  or,  if
sooner,  the purchase of any annuity  contract  pursuant to subparagraph  (a) of
this Paragraph 9.2. Similarly, a Participant whose Beneficiary is other than his
Spouse may  designate,  at the time he  designates  such  Beneficiary,  that the
distribution to such Beneficiary be paid in one or more of such forms in lieu of
the form prescribed in subparagraph 9.1(a). If the designation  permitted in the
previous  sentence is not made  irrevocably  by a  Participant  with  respect to
actions of his Beneficiary or if the  Participant's  Spouse is his  Beneficiary,
and such Participant dies prior to his Retirement, then his Beneficiary may file
with the  Committee  the same  election not more than 60 days  subsequent to the
date of the Participant's death.
The alternate forms of distribution are:

            (a) Annuity: A nontransferable annuity contract,  provided, however,
      that:  (i)  if  a  Participant's  termination  of  employment  is  due  to
      Retirement  and if  such  Participant  has a  Spouse  at the  time of such
      distribution  then, unless the Participant files a written election not to
      receive his  benefits in this form in the manner  prescribed  in Paragraph
      9.3,  such annuity  shall be paid on a fixed annuity basis with 50% of the
      annuity  continued  after  the  Participant's  death to his  Spouse.  Such
      annuity shall be in the form of a "qualified joint and survivor  annuity",
      as that term is defined in Section 417(b) of the Code, and shall be

                                     IX-2





      actuarially  equivalent  to the single life annuity which would be payable
      for the life of the Participant.

            All payments under an annuity contract distributed hereunder must be
      payable not less  frequently  than  annually and must be of  approximately
      equal  amounts,  except  that the  earlier  payments  may exceed the later
      payments and no  contingent  annuitant  option may be elected  which would
      allocate to the  Participant  less than 50% of the actuarial  value of the
      benefits  payable under such contract.  This limitation shall not preclude
      the  election  of an annuity for the life of the  Participant  under which
      payments in equal or lesser amounts are  thereafter  made to his surviving
      Spouse;

            (b) Lump Sum: A lump sum payment payable in the manner prescribed in
      subparagraph 9.1(a) valued as of the Valuation Date designated as the date
      for  distribution of benefits by the Participant or the Beneficiary but no
      later than the April 1st of the calendar year  following the calendar year
      in which the  Participant  attains  age 70 1/2;  provided,  however,  if a
      Participant  was born prior to July 1, 1917, and is not a 5% owner subject
      to the rule set forth in subparagraph  9.5(a), any benefit payable to such
      Participant  shall  commence  no later than the April 1st of the  calendar
      year following the later of (i) the calendar year in which the Participant
      attains  age 70 1/2 or (ii) the  calendar  year in which  the  Participant
      retires. The Committee may accelerate the lump-sum payment in the event of
      hardship; or

            (c) Installments:  Approximately  equal annual  installments paid in
      cash over a fixed period of years subject to minimum payment  requirements
      under the Regulations as prescribed by the Committee. Such period of years
      for the payment of  installments  may  commence as of any  Valuation  Date
      after the  Participant's  termination  of  employment,  as  elected by the
      Participant  or the  Beneficiary,  but no later  than the April 1st of the
      calendar year following the calendar year in which the Participant attains
      age 70 1/2; provided,  however, if a Participant attained age 70 1/2 prior
      to January 1, 1988, except as otherwise  provided in subparagraph  9.4(a),
      any benefit payable to such  Participant  shall commence no later than the
      April 1st of the  calendar  year  following  the later of (i) the calendar
      year in which the Participant attains age 70 1/2 or (ii) the calendar year
      in which the Participant retires. Such installments shall be paid over the
      period of years elected by the  Participant  or the  Beneficiary  provided
      that such period shall not exceed the lesser of (i) 15 years,  or (ii) the
      life  expectancy of the  Participant,  the  Beneficiary  or the joint life
      expectancy of the  Participant  and the  Beneficiary  as determined by the
      Committee  in  accordance  with the Code.  In the event of  hardship,  the
      Committee may accelerate the payment of one or more installments or reduce
      the installment payment period.

      Any Participant or Beneficiary  electing an alternate form of distribution
described  in  subparagraphs  (b)  or  (c)  shall  continue  to  participate  in
Investment Fund  performance with respect to all  undistributed  portions of his
account balance.  In no event shall any payment pursuant to subparagraphs (b) or
(c) be permitted after the Participant's attainment of age 65 unless the method

                                     IX-3





of payment,  on an actuarial basis,  will provide the Participant with more than
50% of the present value of the total payments to be made to the Participant and
the Beneficiary.

      9.3 Notice of Right to Elect Not to Receive  Benefits in Form of Qualified
Joint and Survivor Annuity: Each Participant who elects to have his distribution
paid in the form of an annuity  contract set forth in  Paragraph  9.2(a) and who
would otherwise  receive the qualified  joint and survivor  annuity set forth in
subparagraph  9.2(a)(i)  shall  have a period of 90 days  ending on the  annuity
starting  date to make a  Qualified  Election  not to take such form of  annuity
under the Plan,  and to elect any other  permissible  form of  annuity  or other
optional form of benefit  provided under Paragraph 9.2. A Participant may revoke
his election to take an optional form of benefit at any time during the election
period.  The  Committee  shall  provide to the  Participant  within a reasonable
period prior to the  commencement of benefits a written  explanation of: (i) the
terms  and  conditions  of  qualified  joint  and  survivor  annuity;  (ii)  the
Participant's  right to make,  and the effect of, a Qualified  Election to waive
such form of benefit; (iii) the rights of the Participant's Spouse; and (iv) the
right to make, and the effect of, a revocation of a previous  Qualified Election
to waive the qualified joint and survivor  annuity.  The election of an optional
form of benefit  which  includes  the  payment of an annuity  shall not be given
effect if the  Participant  or any other person who would receive  benefits from
such annuity dies before the purchase of an annuity contract.

      9.4   Distributions Upon Death:

            (a) Except in the case of a Participant  whose  benefits are paid in
      the form of an annuity, as described in subparagraph  9.2(a), in the event
      of the  death  of a  Participant  prior  to  complete  payment  under  any
      allowable form of distribution, the balance of his account under the Trust
      Fund shall be distributed to his Beneficiary in accordance with Paragraphs
      9.1(a) and 9.2; provided,  however,  that such balance will continue to be
      distributed  at least as rapidly as under the  method of  distribution  in
      effect on the Participant's death.

            (b) In the event of the death of a Participant prior to commencement
      of the distribution of his benefit, the Participant's entire benefit shall
      be  distributed  to the  Beneficiary  no later than five  years  after the
      Participant's death; provided,  however, that any such distribution may be
      made in installments  pursuant to subparagraph 9.2(c) if such distribution
      is commenced not later than one year after such Participant's death or, if
      such Beneficiary is the Participant's surviving Spouse, not later than the
      date on which such Participant would have attained age 70 1/2 (or any such
      later date prescribed in the  Regulations.)  If the surviving  Spouse dies
      before payments begin,  subsequent  distributions  shall be made as if the
      Spouse had been the Participant.

            (c) For purposes of this  Paragraph  9.4, any amount paid to a child
      of the  Participant  shall  be  treated  as if it  had  been  paid  to the
      surviving  Spouse if such amount becomes  payable to the surviving  Spouse
      upon  the  child's  attaining  the age of  majority  or such  other  event
      prescribed in the Regulations.

                                     IX-4





      9.5   Commencement of Certain Distributions:

            (a) If a  Participant  who is a 5% owner  attained age 70 1/2 before

      time  during the Plan Year in which such owner  attains  age 66 1/2 or any
      subsequent Plan Year.

            (b)  Unless  a  Participant  or  Beneficiary   elects  otherwise  in
      accordance   with  this  Article  IX,  the  payment  of  the  value  of  a
      Participant's  vested  interest  under the Plan shall begin not later than
      the 60th day after the latest of the close of the Plan Year in which:  (i)
      the Participant attains age 65; (ii) the Participant terminates employment
      with the  Employer  or  other  Affiliated  Company;  or  (iii)  the  tenth
      anniversary of the year in which the Participant  commenced  participation

      and 9.2, a Participant or his  Beneficiary may elect, on or after the date
      of occurrence of an event specified in Paragraph  9.5(b),  to receive,  as
      soon as practicable after the filing of an election with the Committee,  a
      distribution  in one  lump-sum  payment  of all  amounts  credited  to his
      account in Investment Funds B,C,E and G or, effective July 1, 1990, in all
      Investment Funds.


            (b) A  Participant  or his  Beneficiary  may make an election  under
      Paragraph  9.5(a) if one of the following events shall have occurred on or
      after  January  1,  1985:   (i)  the  Plan  is   terminated   without  the
      establishment  of or  maintenance  of another  defined  contribution  plan
      (other than a plan defined in Section 4975(e)7 of the Code); (ii) there is
      a disposition  by the Company of  substantially  all of the assets (within
      the  meaning of Section  409(d)(2)  of the Code) used by the  Company in a
      trade or  business,  and the  Participant  continues  employment  with the
      corporation  acquiring the assets;  or (iii) there is a disposition by the
      Company of the Company's  interest in a subsidiary  (within the meaning of
      Section 409(d)(3) of the Code), and the Participant  continues  employment
      with the subsidiary.

      9.7 Minimum Distribution Requirements:  All distributions under Article IX
shall be determined and made in accordance  with Section  401(a)(9) of the Code,

                                     IX-5





      9.8 Waiver of 30 Day Notice:  If a  distribution  is one to which Sections
401(a)(11) and 417 of the Internal Revenue Code do not apply,  such distribution
may  commence  less  than  30 days  after  the  notice  required  under  Section
1.411(a)-11(c) of the Income Tax Regulations is given, provided that:

            (1) the plan administrator  clearly informs the participant that the
      participant  has a right to a period of at least 30 days  after  receiving
      the  notice  to  consider  the  decision  of  whether  or not to  elect  a
      distribution (and, if applicable, a particular distribution option), and

            (2) the  participant,  after  receiving  the  notice,  affirmatively
      elects a distribution.

                                   ARTICLE X

                                  WITHDRAWALS

      10.1  Withdrawals of Contributions:

            (a) General:  Subject to the limitations set forth in Paragraph 10.3
      with  respect  to  Basic  and  Supplemental   Pre-Tax   Contributions,   a
      Participant may make  withdrawals  from his account balance in the various
      Investment  Funds at any  time  prior to his  termination  of  employment,
      without  the  consent of the  Committee,  as  hereinafter  set forth.  The
      provisions of this Article X shall apply to deferred  vested  Participants
      who are not current employees on the same basis that such provisions apply
      to currently employed Participants.

            (b) Procedure:  All requests for  withdrawals  shall be initiated by
      submission  of the  appropriate  Plan form to the local  administrator  at
      least 5 days  before the 15th of the month or the end of the month that is
      the  Valuation  Date with respect to the proposed  withdrawal,  unless the
      Committee  resolves  that  requests  for  withdrawals  may be initiated by
      telephoning the  representative of the Trustee at the number stated in the
      summary plan  description  of the Plan and following the  instructions  of
      that representative.  Written confirmation of the transaction will be sent
      to  the   Contributing   Participant  by  the  Trustee  and  such  written
      confirmation is binding unless the Contributing  Participant  demonstrates
      an error in such written  confirmation within the number of days stated on
      the written  confirmation.  The value of a Participant's  accounts will be
      valued on the Valuation  Date next following the date on which the request
      is approved.  Distribution shall be made in a lump-sum cash payment within
      15 days or as soon as  practicable.  All such  withdrawals  shall be taken
      proportionately  from each of the Participant's  Investment Funds,  except
      that  if  the  Committee  determines  in its  sole  discretion  that  such
      proportionate   withdrawal  would  violate  any  Securities  and  Exchange
      Commission  ("SEC")  rule  concerning  the sale of stock by an  officer or
      member of the board of directors of any company of which the stock is held
      in the Plan, the withdrawal  shall be taken  proportionately  from each of
      the affected  Participant's  Investment Funds other than the NL Stock Fund
      or the Dresser/Tremont Stock Fund or any other company stock fund in which
      transactions would violate any SEC rule.

            (c) Limitations:  A Participant is not allowed to take more than two
      withdrawals  in any calendar year, nor any withdraw an amount of less than
      one hundred dollars ($100).

            (d) Source of funds: All withdrawals  shall be made in the following
      sequence and for  purposes of this  Paragraph  where  reference is made to
      Basic and  Supplemental  Pre-Tax  Contributions  or Basic and Supplemental
      After-Tax  Contributions,  such terms  shall mean the lesser of the actual
      amount of such  unwithdrawn  contributions  or the  current  market  value
      thereof as of the applicable Valuation Date:


                                     X-1





                  (i) all of his Basic and Supplemental After-Tax  Contributions
            made prior to 1987;

                  (ii)  all or  part  of his  post-1986  Supplemental  After-Tax
            Contributions,  and  all or  part of the  increments  earned  on all
            Supplemental  After-Tax  Contributions;  

                  (iii)   all  or  part  of  his   post-1986   Basic   After-Tax
            Contributions, and all or part of the increments earned on all Basic
            After-Tax Contributions;

                  (iv)  all or part  of  that  portion  of his  account  balance
            attributable  to  Employer  Contributions  which are  fully  vested,
            including  increments  earned thereon,  subject to the provisions of
            Paragraph 10.4. For purposes of determining his vested percentage at
            the time of such  withdrawal,  a  Participant  who has  completed at
            least 1,000 Hours of Service or six Months of Service at the time of
            the withdrawal shall be deemed to have completed one year of Vesting
            Service;

                  (v)  all or part  of  Employer  Contributions  made  prior  to
            January 1, 1974 to the Predecessor Plan, including increments earned
            thereon,   Rollover  Contributions,   Direct  Rollovers  and  direct
            transfers from another qualified trust as described in subparagraphs
            4.10(b), (c) and (d) including increments earned thereon;

                  (vi)  all  or  part  of his  Basic  and  Supplemental  Pre-Tax
            Contributions,   provided  he  has  satisfied  the  requirements  of
            Paragraphs 10.3 or 10.6.

      10.2 Suspensions:  A Participant who makes a withdrawal shall be suspended
from making any further  Basic  After-Tax or  Supplemental  Contributions  for a
period of three  months,  effective  as of the  Valuation  Date  upon  which the
withdrawal is based. A Participant who makes a withdrawal  pursuant to Paragraph
10.6 shall be suspended from making any further Basic Pre-Tax,  Basic  After-Tax
or Supplemental  Contributions for a period of three months, effective as of the
Valuation Date upon which the withdrawal is based.

      10.3  Withdrawal  of  Basic  and   Supplemental   Pre-Tax   Contributions:
Notwithstanding the provisions of Paragraph 10.1, Basic and Supplemental Pre-Tax
Contributions, including the increments earned thereon, may not be withdrawn by,
or otherwise  distributed  to, a Participant  until the earliest to occur of the
Participant's Retirement, Disability, death, separation from service, attainment
of age 59 1/2 or hardship (as  determined by the  Committee in  accordance  with
Paragraph 10.6).  Notwithstanding the foregoing,  in the case of a withdrawal on
account of hardship,  no  post-1988  earnings on Basic or  Supplemental  Pre-Tax
Contributions  may be withdrawn by, or otherwise  distributed  to, a Participant
except to the extent permitted by Regulations.

      10.4 Restrictions on Withdrawal of Employer Contributions: Notwithstanding
the  provisions  of Paragraphs  10.1,  10.2 and 10.6,  no  Participant  shall be
permitted to make a withdrawal under  subparagraph  10.1(c) until the amounts to
be  withdrawn  have been held in the Trust Fund for a period of 24 full  months.
Such period shall be measured  from the day such amounts are actually  deposited
in  the  Trust  Fund  until  the  day of  withdrawal;  provided,  however,  that
Participants with

                                     X-2





not less  than 60  months  of  participation  in the Plan  (including,  for this
purpose,  participation  in the Prior  Plan)  may make  withdrawals  subject  to
Paragraph 10.2 under  subparagraph  10.1(c)  without  regard to the  restriction
imposed by this Paragraph 10.4.

      10.5 Special Rules Affecting Withdrawals:  Except as provided in Paragraph
10.6, no withdrawal other than as provided in subparagraph (d) of Paragraph 10.1
may be made by a  Participant  while a suspension  for a prior  withdrawal is in
effect.  If a Participant  was suspended  from making Basic  Contributions  as a
result of a withdrawal  described under  Paragraph 10.1, and thereafter  resumes
making Basic  Contributions,  such Basic Contributions shall be, for a period of
time equal to the period of suspension,  at a rate of  contribution  not greater
than the rate  contributed  as Basic  Contributions  at the time the  suspension
began.

      10.6  Hardship Withdrawals:

            (a)  General  rules:   After  all  withdrawals   permissible   under
      Paragraphs  10.1 and 10.4, a  Participant,  in the case of  immediate  and
      heavy  financial  need,  may apply to the Committee to withdraw all or any
      portion of his vested  account  balance  under the Plan.  If the Committee
      determines in accordance with  nondiscriminatory  and objective guidelines
      promulgated  by  the  Committee   (which  shall  be  consistent  with  the
      Regulations subject to differences in rules and regulations  applicable to
      different  classifications of contributions and increments,  and uniformly
      applicable  to all  Participants),  in accordance  with any  guidelines or
      Regulations issued by the Secretary of the Treasury, and with the facts of
      the particular  case,  that an immediate and heavy  financial need exists,
      the  Committee  may direct the Trustee to  distribute  such portion of the
      Participant's  account balance at such time and subject to such conditions
      as the Committee in its sole  discretion  shall  determine is necessary to
      satisfy  such  immediate  and  heavy  financial  need  and  which  may not
      reasonably  be obtained by other  resources of the  Participant  including
      resources of the Participant's  spouse,  children or dependents reasonably
      available to the  Participant.  The Committee may require any  Participant
      who applies for a withdrawal pursuant to this Paragraph 10.6 to provide it
      with  such  financial   information  as  may  be  required  to  make  such
      determination.

            (b)  Hardship  amounts  and  purposes:  Subject  to the  Committee's
      guidelines,  such withdrawals may be made in the event of an immediate and
      heavy  financial  need  arising  from (i) medical  expenses  described  in
      Section 213(d) of the Code previously  incurred (or,  effective January 1,
      1992, previously incurred or necessary to be incurred) by the Participant,
      his spouse, or dependents, (ii) the purchase (excluding mortgage payments)
      of the  Participant's  primary  residence,  whether  such  residence  is a
      previously existing structure or a proposed structure under contract to be
      newly  constructed (iii) payment of tuition or, effective January 1, 1992,
      related  educational  fees, for the next semester or quarter or, effective
      January 1, 1992, year, of post-secondary education of the Participant, his
      spouse,  or  dependents,  (iv) the need to  prevent  the  eviction  of the
      Participant from his principal residence or foreclosure on the mortgage of
      the Participant's principal residence, or (v) any other event specifically
      identified in  regulations  or other  guidance  from the Internal  Revenue
      Service as a  hardship  for which a  qualified  pension  benefit  plan may
      permit a hardship  withdrawal under Section 401(k) of the Code and related
      regulations.  Effective  January 1, 1992,  the  withdrawal  may include an
      additional  amount  necessary to pay any federal,  state,  or local income
      taxes or penalties (including  additional taxes under Section 72(t) of the
      Code) that are reasonably expected to result from the withdrawal.

                                  ARTICLE XI

                      NAMED FIDUCIARY AND ADMINISTRATION

      11.1 Pension and Employee Benefits  Committee:  The Committee shall be the
Pension and Benefits Committee of NL Industries,  which is a committee appointed
by the Board. The charter and bylaws of the Committee shall govern wherever such
investments  are in direct  conflict with the provisions of this Article XI. If,
however, the Pension and Employee Benefits Committee should cease to exist then,
the Board shall  appoint at least three  persons as members of the Committee who
shall be subject to removal by the Board at any time. A member of the  Committee
may resign by giving the Board not less than 30 days written  notice  unless the
Board accepts a lesser period of notice.

      Names of the  current  members of the  Committee  are  available  from the
Secretary of the Committee.  The Committee shall be the Plan's "named fiduciary"
as that term is defined  in ERISA and shall,  except as  provided  in  Paragraph
11.2,  provide for the funding,  maintenance and administration of the Plan. Any
act which the Plan  authorizes  or requires the Committee to do may be done at a
meeting of the  Committee by a majority of the members then voting.  The members
of the Committee  shall serve without  compensation  for their services as such,
but all expenses of the Committee in the  performance  of their duties under the
Plan (including  compensation  for legal counsel,  accountants,  consultants and
agents) shall be paid  proportionately  by each Employer or, at the  Committee's
direction, out of the Trust Fund.

      11.2  Authority of the Committee:

            (a) The  Committee  shall have the  following  powers of the Company
      with respect to the Plan:

                  (i)   to appoint, remove or replace any Trustee;

                  (ii) to appoint,  remove or replace any one or more investment
            advisors or investment managers under the Plan;

                  (iii) to  appoint,  remove or replace any other  fiduciary  or
            named fiduciary of the Plan;

                  (iv) to amend  the Plan and the Trust as may be  necessary  or
            appropriate to facilitate  their  administration  or operation or to
            ensure the continued  qualification  of the Plan and the  tax-exempt
            status of the Trust  under  Sections  401(a) and 501(a) of the Code,
            respectively,  provided such amendment does not increase  materially
            the cost to the Company funding or administering the Plan; and

                  (v) to secure and maintain the qualification of the Plan under
            applicable law.

            (b) The  Board  shall  retain  power  and,  except  as  provided  in
      subparagraph (a)(iv) above, the Committee shall not have the power:

                  (i) to amend, suspend or terminate the Plan, any contributions
            thereunder  or the Trust,  in whole or in part,  at any time and for
            any reason;

                  (ii)  to provide the proper funding of the Plan; and

                  (iii) to monitor periodically the performance of the Committee
            and to determine,  in connection  with such  monitoring,  whether to
            continue any delegation to or  responsibility  of the Committee with
            respect to the Plan.

      11.3 Delegation of Authority: The Committee shall appoint a Secretary, who
need be neither a Participant nor a member of the Committee.  The Secretary,  or
such other person as the Committee may designate, duly shall record all acts and
determinations  of the  Committee  and  maintain  all record  books or documents
necessary  for the  administration  of the Plan.  The  Committee  may  establish
procedures for allocating  fiduciary  responsibilities  among the members of the
Committee  and may  designate  any one or more  persons to  exercise  any of its
powers,  including any of its powers as administrator,  or to execute or deliver
any  instrument or make any payment on its behalf;  provided,  however,  that no
person  other  than a member of the  Committee,  the  Trustee  or an  investment
manager  shall have any  authority  or  control,  whether or not  discretionary,
respecting the management or disposition of the Plan's assets.

      11.4  Administrator:  The Committee shall serve as  "administrator" of the
Plan as that term is defined in ERISA. The Committee,  as  administrator,  shall
have the authority and responsibility to:

            (a)  control  the  operation  and  administration  of  the  Plan  in
      accordance with the terms of the instruments and resolutions governing the
      Plan and any related Trust;

            (b) determine benefit eligibility and to certify such eligibility to
      any other fiduciaries;

            (c) establish  procedures and adopt rules and regulations of uniform
      application  as it  deems  necessary  or  appropriate  for  the  effective
      administration of the Plan;

            (d) hire persons and  organizations  to provide  legal,  accounting,
      investment  advisory and other  services  necessary or  beneficial  to the
      Plan;

            (e) issue directions to the Trustee to pay any fees, taxes,  charges
      or other costs  incidental to the operation and  management of the Plan by
      the administrator pursuant to this Paragraph 11.4;

            (f) issue  directions to the Trustee as to the amount of Plan assets
      to be held in cash to assure proper liquidity;

            (g) prepare and file all reports and returns required to be filed by
      the Plan with any agency of government;

            (h)  comply  with all  disclosure  requirements  imposed by state or
      federal law;

            (i) maintain all records of the Plan other than those required to be
      maintained by the Trustee or by any fiduciary of the Plan; and

            (j) perform all other acts  required by law to be  performed  by the
      administrator of the Plan.

      The Committee shall have all powers  necessary to carry out the provisions
of the Plan and shall have the absolute,  unilateral,  and  exclusive  right and
power to interpret, construe and construct the terms and provisions of the Plan,
including,  without  limitation,  correcting any error or defect,  supplying any
omission or reconciling any inconsistency,  and making all  determinations  that
may impact a claim for benefits,  including factual  determinations.  Subject to
Paragraph 11.5, the Committee's decisions,  interpretations,  determinations and
actions in respect  thereof shall be conclusive  and binding upon each Employer,
Participant, Beneficiary and all other persons and entities.

      11.5 Appeals  Procedure:  The Committee,  as  administrator,  shall act as
claims  fiduciary  except to the extent that the  Committee  has  delegated  the
function to someone else. All claims for benefits under the Plan must be made in
writing and shall be directed to the  attention  of the claims  fiduciary.  Upon
receipt of the claim, the claims fiduciary shall notify the claimant in a timely
fashion of the time periods within which any notice of denial of claim,  request
for review of claim,  or  decision on review of denial of claim must be given in
accordance with subparagraphs (a) through (c) below.

            (a) If the claims  fiduciary  determines that any individual who has
      claimed a right to  receive  benefits  under the Plan is not  entitled  to
      receive  all or any part of the  benefits  claimed,  it shall  inform  the
      claimant in writing of its  determination  and of the reasons  therefor in
      layman's terms,  with specific  reference to pertinent Plan provisions and
      any additional  material  necessary for the claimant to perfect his claim.
      The notice of denial shall also include a summary description or a copy of
      the text of the review  procedures  set forth below.  Such notice shall be
      made within a  reasonable  period of time but not later than 90 days after
      receipt of the claim, unless special circumstances require
      an  extension  of time for  processing.  If such an  extension  of time is
      required,  the  claims  fiduciary  shall  furnish  written  notice  of the
      extension to the claimant  prior to the  termination of the initial 90 day
      period.  In no event shall such extension  exceed a period of 90 days from
      the end of such initial  period.  The extension  notice shall indicate the
      special circumstances requiring an extension of time and the date by which
      the claims fiduciary expects to render a final decision.  If notice of the
      denial of claim is not furnished  within the time limits  specified above,
      the claim shall be deemed  denied and the  claimant  shall be permitted to
      proceed to the  review  process  described  in  subparagraphs  (b) and (c)
      below.

            (b) Within 60 days of the  receipt by the  claimant  of the  written
      notice of denial of the claim,  the  claimant  may file a written  request
      with the claims  fiduciary to conduct a full and fair review of the denial
      of the  claimant's  claim for benefit.  In connection  with the claimant's
      appeal, the claimant may review pertinent  documents and may submit issues
      and comments in writing.

            (c) The claims  fiduciary  shall promptly advise the claimant of its
      decision on the  claimant's  request for review.  Such  decision  shall be
      written in a manner  calculated to be  understood  by the claimant,  shall
      include  specific  reasons for the decision,  and shall  contain  specific
      references to pertinent Plan  provisions upon which the decision is based.
      The  decision  on  review  shall be made no later  than 60 days  following
      receipt of the  claimant's  request for review.  If special  circumstances
      require an extension of time for processing,  a decision shall be rendered
      not later than 120 days  following  receipt  of the  request  for  review.
      Written  notice of any such  extension  shall be furnished to the claimant
      prior to the commencement of the extension.

      11.6 Reliance on Reports and Certificates: The Committee shall be entitled
to rely conclusively  upon all tables,  valuations,  certificates,  opinions and
reports  furnished  by any  Trustee,  accountant,  controller,  counsel or other
person who is employed or engaged for such purposes.

      11.7 Member's Own Participation:  No member of the Committee may act, vote
or otherwise influence a decision of the Committee  specifically relating to his
own participation under the Plan.

      11.8 Exemption from Bond: No member of the Committee  shall be required to
give bond for the  performance of his duties  hereunder,  unless required by law
which cannot be waived.

      11.9  Persons  Serving  in Dual  Fiduciary  Roles:  Any  person,  group of
persons,  corporations,  firm or  other  entity,  may  serve  in more  than  one
fiduciary capacity with respect to the Plan, excluding the ability to serve both
as Trustee and as a member of the Committee.

      11.10  Indemnification:  Each member of the  Committee  and any  Employee,
director  or officer  of an  Employer,  who is  considered  to have  served in a
fiduciary capacity with respect to the Plan, shall be indemnified by the Company
against expenses (including the amount of any liability imposed in the form of a
money  judgment,  civil  penalty,  excise  tax,  as  well  as  amounts  paid  in
settlement)  reasonably  incurred by him in connection with any action,  suit or
proceeding  to which he may be a party or with which he shall be  threatened  by
reason of his being  considered to have served in a fiduciary  capacity,  to the
fullest  extent  permitted  by the  By-Laws of the  Company  and by law. No such
individual  shall be liable with respect to a breach of fiduciary duty if such a
breach  occurred  before  he  became a  fiduciary  or after  he  ceased  to be a
fiduciary.

      11.11  Liability of  Fiduciaries:  No person,  including any Trustee,  who
shall at any time be considered to be or to have been a fiduciary,  as such term
is  defined   under  ERISA,   shall  be  liable  for  the  breach  of  fiduciary
responsibility  of any other  person who is at any time  considered  to be or to
have been a fiduciary, except as provided in Section 405(a) of ERISA.

      11.12  Liability of Named  Fiduciaries:  No  fiduciary  who at any time is
considered to be or to have been a "named fiduciary," as that term is defined in
ERISA, shall be liable for an act or omission of any person,  designated by such
fiduciary  to  carry  out  fiduciary  responsibilities,  or to whom  such  named
fiduciary has allocated the  performance of his own fiduciary  responsibilities,
except as provided in Section 405(c)(2) of ERISA.

                                  ARTICLE XII

                                THE TRUST FUND

      12.1 The Trust: All assets of the Plan, including earnings thereon,  shall
comprise the Trust Fund.  Except as provided in Paragraph  12.2,  no part of the
principal  or income of the  Trust  Fund  shall be used  for,  or  diverted  to,
purposes  other  than  the  exclusive  benefit  of the  Participants  and  their
Beneficiaries.  No person shall have any interest in or right to any part of the
earnings of the Trust Fund, except as and to the extent provided in the Plan and
under federal law. The Trustee shall invest, reinvest,  manage, control and make
disbursements  from the Trust Fund in accordance with the provisions of the Plan
and the Trust,  subject,  however,  to the power of the  Committee to appoint an
investment manager pursuant to subparagraph 11.2(a)(ii).

      12.2  Irrevocability  of Company  Contributions:  All contributions by the
Company or any Employer  shall be  irrevocable  when made, and the Company shall
have no  right,  title or  interest  of any kind in the  Trust  Fund;  provided,
however, that if the Plan and Trust shall not initially, or after any amendment,
be determined by the Internal  Revenue Service to be qualified under  applicable
provisions  of the Code,  or if a  contribution  made by any  Employer  shall be
disallowed  as a deduction  under  applicable  provisions  of the Code,  or if a
contribution  of any  Employer  is  made by  mistake  of  fact,  then  upon  the
Employer's  written  request  such  affected  Employer  contributions  shall  be
returned to the Company or to the  appropriate  Employer  within 30 days of such
request; provided,  however, that no contributions may be returned more than one
year after the date of the  determination of  disqualification,  disallowance of
the deduction of mistaken payment, respectively.

      12.3 Exclusive  Benefit:  Subject to the provisions of Paragraph  12.2, it
shall be  impossible at any time for any part of the Trust Fund to revert to the
Company or to any  Employer,  or to be used for or diverted to any purpose other
than the  exclusive  benefit  of  Participants,  former  Participants  and their
Beneficiaries,  or for defraying  expenses of  administering  the Plan and Trust
Fund.  No person  shall have any  interest  in or right to any part of the Trust
Fund,  except as, and to the extent,  provided in the Plan and under  federal or
state law.



                                    XII-1





                                 ARTICLE XIII

                       AMENDMENT AND TERMINATION OF PLAN

      13.1 Right to Amend or Terminate:  The Board shall have the right,  at any
time  and  from  time  to  time,  to  amend  in  whole  or in part of any of the
provisions of the Plan or to terminate the Plan, provided that no such amendment
may affect the rights,  duties or  responsibilities  of the Trustee  without its
consent.  Any  amendment  or  termination  of the Plan,  other than an amendment
described in subparagraph  11.2(a)(iv),  shall become effective upon delivery to
the  Committee and the Trustee of a written  instrument  executed by the Company
pursuant to written resolutions of the Board, as of the effective date specified
therein.  To the extent that the Board  delegates  authority to the Committee to
amend the Plan,  the  written  instrument  shall be  executed  by the  Committee
pursuant to written resolution of the Committee. The written instrument may be a
certified copy of the applicable  resolutions.  Amendments of the Plan described
in subparagraph 11.2(a)(iv) shall become effective as of the effective date of a
written  instrument  executed  by the  Committee.  Any  amendment  of  the  Plan
requiring the Trustee's consent shall become effective as of such specified date
immediately  upon such  consent.  Except as may be  necessary  to  maintain  the
qualification of the Plan pursuant to Sections 401(a) and 501(a) of the Code and
subject to the provisions of Paragraph 12.2, no such amendment or termination of
the Plan shall  authorize or permit any part of the Trust Fund to be used for or
directed to purposes other than the exclusive  benefit of Participants and their
Beneficiaries,  or,  except as may be required  by  governmental  authority,  to
affect  adversely either the benefits of Participants  already  retired,  or the
Trust Fund securing such benefit.

      13.2 Mandatory Amendments:  The Contributions of each Employer to the Plan
are intended to be:

            (a)   deductible under the applicable provisions of the Code;

            (b) except as otherwise  prescribed by applicable  law,  exempt from
      the Federal Social Security Act;

            (c) except as otherwise  prescribed by applicable  law,  exempt from
      withholding under the Code; and

            (d) excludible from any  Participant's  regular rate of pay, as that
      term is defined under the Fair Labor Standards Act of 1938, as amended.

      The Company shall make such  amendments to the Plan as may be necessary to
carry out this intention, and all such amendments may be made retroactively.

      13.3 Distribution of Accounts Upon Plan  Termination:  In the event of and
upon the Company's  termination  or partial  termination of the Plan or complete
discontinuance  of  contributions  other than by reason of being merged into, or
consolidated  with, the plan of another Affiliated  Company,  whether or not the
Trust also  terminates  concurrently  therewith,  the interest in the portion of
each  Participant's  account  balance  attributable  to  Employer  Contributions
theretofore  made on behalf  of such  Participant  shall  become  fully  vested.
Subject to the provisions of Article XIV, any unallocated  forfeitures  shall be
reallocated  to the accounts of Employees  who are  Participants  on the date of
such termination or complete  discontinuance  in the proportion that the account
balances of each such individual  Participant  bears to the account  balances of
all persons who are Participants on such date,  provided that such  reallocation
does not discriminate in favor of Employees who are officers,  shareholders,  or
highly  compensated.  Unless  the  Board  directs  otherwise,  such  a  complete
discontinuance  of  contributions or a termination of the Plan shall not, except
as  otherwise   permitted  under  Paragraph  9.5,  accelerate  any  payments  or
distributions to or for the benefit of the  Participants or their  Beneficiaries
or estates,  but the Trust Fund shall continue to be held for  distribution  and
application in the manner to be prescribed by the Board.



                                    XIII-1





                                  ARTICLE XIV

                         LIMITATIONS ON CONTRIBUTIONS

      14.1  Priority of this Article:  The  provisions of this Article XIV shall
govern notwithstanding any other provisions of the Plan.

      14.2 Limitation to Annual  Additions:  Annual Additions to a Participant's
account in respect of any Plan Year may not exceed the lesser of:

            (a)  $30,000,  or, if greater,  one-fourth  of the  defined  benefit
      dollar  limitation  set forth in  Section  415(b)(1)(A)  of the Code as in
      effect for such Plan Year; or

            (b) 25  percent  of the  Participant's  compensation  as  defined in
      Section  415(c)(3)  of the Code for such Plan  Year,  but in no event more
      than the first $150,000 of compensation, as adjusted for cost of living to
      the extent permitted by the Code and the Regulations.

      For this purpose,  the term "Annual  Additions"  shall mean the sum of the
following  amounts  which,  without  regard to this Article XIV, would have been
credited to the Participant's Account for any Plan Year under the Plan and under
any other  defined  contribution  plans of the  Employer  or an  Affiliate:  (i)
Employer Contributions; (ii) Basic Pre-Tax Contributions;  (iii) Basic After-Tax
Contributions;  (iv) Supplemental Contributions; (v) forfeitures, if applicable;
and, with respect to any plan  maintained by the Employer or an Affiliate;  (vi)
contributions  allocated to any individual  medical  account  defined in Section
415(l)(1)  of the  Code;  and (vii) in the case of a  Participant  who is a "key
employee," as defined in Section 416(i) of the Code,  the amount  allocated to a
separate  account  established  for  postretirement  medical  or life  insurance
benefits  or such  Participant  described  in  Section  419A(d)(1)  of the Code.
Without  limiting  the  scope of the  immediately  preceding  sentence,  for the
purpose of clarity,  in addition to other  amounts set forth in  regulations  or
other  guidance  issued  under  Section  415 of  the  Code  by  the  appropriate
governmental  authority,  amounts  paid to the Trust  pursuant  to the terms and
provisions  of the Plan to pay brokerage  commissions  on purchases and sales of
Employer  Stock  shall not be  treated  as  annual  additions.  The term  Annual
Additions  shall  not  include  any  Rollover  Contributions  made  pursuant  to
Paragraph  4.10.  Solely  for  the  purposes  of  subparagraph  14.4(a),  Annual
Additions  shall  include  a  participant's   contributions  under  a  qualified
cost-of-living   arrangement   described  in  Section  415(k)(2)  of  the  Code.
Contributions  shall continue to be treated as Annual Additions  notwithstanding
that such contributions are excess deferrals,  excess  contributions,  or excess
aggregate contributions or notwithstanding that such excess deferrals and excess
contributions have been corrected through distribution or recharacterization.

      14.3 Adjustments of Annual Additions:  In the event that the amounts which
would  otherwise  be  allocated  to a  Participant's  account must be reduced by
reason of the limitations of Paragraph 14.2, such reduction shall be made in the
following order of priority, but only to the extent necessary:

            (1)  The  amount  of  the   Participant's   Supplemental   After-Tax
      Contributions,  exclusive of any  earnings of the Trust Fund  attributable
      thereto, shall be refunded to the Participant; then

            (2) The amount of the Participant's  Basic After-Tax  Contributions,
      exclusive of any earnings of the Trust Fund attributable thereto, shall be
      refunded to the Participant; then

            (3) To the extent  permitted  by the Code and the  Regulations,  the
      amount of Basic and Supplemental Pre-Tax  Contributions,  exclusive of any
      earnings of the Trust Fund attributable thereto,  shall be refunded to the
      Participant or, to the extent required by law shall be held unallocated in
      a suspense  account and shall be applied,  as directed by the Committee in
      accordance  with  the law and  regulations,  as a  credit  to  reduce  the
      contributions  of the  Employer for the next Plan Year and in the event of
      termination of the Plan shall be returned to the Employer; and then

            (4)  Employer  Pension  Feature  Contributions   allocable  to  such
      Participant  in respect of such Plan Year shall be reduced  and the amount
      of such reduction  shall be utilized to reduce  Employer  Pension  Feature
      Contributions which would otherwise be made to the Plan.

            (5) Employer Matching Contributions allocable to such Participant in
      respect  of such  Plan  Year  shall  be  reduced  and the  amount  of such
      reduction  shall be utilized  to reduce  Employer  Matching  Contributions
      which would otherwise be made to the Plan.


      14.4  Participant Covered Under Defined Benefit Plan:

            (a) Subject to subparagraphs 14.4(c) and 14.4(d), in the event that,
      in any Plan  Year  and with  respect  to any  Participant,  the sum of the
      "Defined  Contribution  Fraction" (as defined in subparagraph 14.4(b)) and
      the "Defined Benefit Fraction" (as defined in subparagraph  14.4(b)) would
      otherwise  exceed 1.0, then the benefit  payable under the defined benefit
      plan or plans shall be reduced in accordance  with the  provisions of that
      plan or those plans,  but only to the extent necessary to ensure that such
      limitation is not  exceeded.  If this  reduction  does not ensure that the
      limitation  set forth in this  Paragraph  14.4 is not  exceeded,  then the
      Annual  Addition to any defined  contribution  plan,  other than the Plan,
      shall be reduced in accordance  with the  provisions of that plan but only
      to the extent necessary to ensure that such limitation is not exceeded.

            (b) For purposes of Paragraph  14.4, the following  terms shall have
      the following meanings:

                  (1)  "Defined  Contribution  Fraction"  shall mean,  as to any
            Participant  for any Plan Year,  a fraction,  (A) the  numerator  of
            which is the sum of  Annual  Additions,  for the  Plan  Year and all
            prior  Plan  Years,  as of the  close of the  Plan  Year and (B) the
            denominator  of  which  is the sum of the  lesser  of the  following
            amounts,  determined  for such Plan Year and for each  prior Year of
            Service (i) the product of 1.25 multiplied by the dollar  limitation
            in  effect  for such year  under  subparagraph  14.2(a)  or (ii) the
            product  of 1.4  multiplied  by the  amount  which may be taken into
            account under  subparagraph  14.2(b) with respect to the Participant
            for such year;  provided,  however,  that for years  ending prior to
            January 1, 1976, the numerator of such fraction shall in no event be
            deemed to exceed the  denominator  of such  fraction;  and,  further
            provided,   that  the   Committee,   in   determining   the  Defined
            Contribution  Fraction  may  elect to use the  special  transitional
            rules  permitted  by  Section  415 of the Code  and the  Regulations
            thereunder; and

                  (2)  "Defined   Benefit   Fraction"  shall  mean,  as  to  any
            Participant  for any Plan Year,  a fraction,  (A) the  numerator  of
            which is the projected annual benefit (determined as of the close of
            the  Plan  Year  and in  accordance  with  the  Regulations)  of the
            Participant  under any defined  benefit plan (as defined in Sections
            414(j) and 415(k) of the Code)  maintained  by the Company or any of
            its  Affiliates  and (B) the  denominator  is the  lesser of (i) the
            product of 1.25 multiplied by the dollar  limitation in effect under
            Section  415(b)(1)(A)  of the Code for  such  Plan  Year or (ii) the
            product of 1.4  multiplied  by an amount equal to 100 percent of the
            Participant's  average  compensation for his high 3 years within the
            meaning of Section 415(b)(3) of the Code for such Plan Year.

            (c) In the case of a Participant with respect to whom the sum of the
      Defined Contribution Fraction and the Defined Benefit Fraction exceeds 1.0
      with respect to the last Plan Year  beginning  before  January 1, 1983, an
      amount,  determined in accordance with the Regulations,  may be subtracted
      from the numerator of the Defined  Contribution  Fraction  (not  exceeding
      such numerator) so that the sum of such Participant's Defined Contribution
      Fraction and his Defined Benefit Fraction  computed under paragraph (a) of
      this  Paragraph  14.4 does not exceed 1.0 for the last Plan Year beginning
      before January 1, 1983.

            (d) Notwithstanding the foregoing provisions of this Paragraph 14.4,
      in  determining  the maximum  Annual  Addition for any Plan Year beginning
      before  January 1, 1987,  the Annual  Addition  shall not be recomputed to
      treat  all  Basic  After-Tax   Contributions  and  Supplemental  After-Tax
      Contributions as an Annual Addition.

                                  ARTICLE XV

                             TOP-HEAVY PROVISIONS

      15.1  Applicability of Top-Heavy  Provisions:  If the Plan is or becomes a
Top-Heavy  Plan  in any  Plan  Year,  the  provisions  of this  Article  XV will
supersede any conflicting  provisions in the Plan during each Plan Year in which
the Plan is a Top-Heavy Plan. In the event that any provision of this Article XV
is no longer  necessary for the Plan to meet the  requirements of Section 401(a)
or other  applicable  sections of the Code,  such  provision  shall  immediately
become null and void and shall no longer apply  without the necessity of further
amendment of the Plan.

      15.2  Definitions:  As used in this Article XV, the following  terms shall
have the meanings set forth below:

            (a) "Determination  Date" shall mean, with respect to any Plan Year,
      the last day of the preceding Plan Year.

            (b) "Key  Employee"  shall  have the  meaning  set forth in  Section
      416(i) of the Code. For purposes of determining Key Employees  pursuant to
      this  subparagraph,  "compensation"  shall have the meaning  prescribed in
      Section 414(s) of the Code or, to the extent  required by the Code and the
      Regulations, Section 1.415-2(d) of the Regulations.

            (c) "Non-Key Employee" shall mean a "Non-Key Employee" as defined in
      Section 416(i)(2) of the Code and the Regulations promulgated thereunder.

            (d)   "Top-Heavy Plan" shall mean a "top-heavy plan" as defined in
      Section 416(g) of the Code.

            (e)  "Aggregation  Group"  shall  mean the  group  composed  of each
      qualified  retirement  plan of the Company or an  Affiliate in which a Key
      Employee is a participant and each other qualified  retirement plan of the
      Company  or an  Affiliate  which  enables  a  plan  of the  Company  or an
      Affiliate in which a Key  Employee is a  participant  to satisfy  Sections
      401(a)(4) or 410 of the Code. In addition, the Company may choose to treat
      any other qualified  retirement plan as a member of the Aggregation  Group
      if such Aggregation Group will continue to satisfy Sections  401(a)(4) and
      410 of the Code with such plan being taken into account.

      15.3 Determination of Top-Heavy Status: The Plan shall be a Top-Heavy Plan
for  any  Plan  Year  if it is  determined  to be a  Top-Heavy  Plan  as of  the
Determination Date applicable to such year. For purposes of determining  whether
the Plan is a Top-Heavy Plan, all qualified  retirement  plans maintained by the
Company or an  Affiliated  Company  shall be  aggregated to the extent that such
aggregation is required  under the  applicable  provisions of Section 416 of the
Code.  All other  qualified  retirement  plans  maintained  by the Company or an
Affiliated  Company shall be aggregated  only if elected by the Company and only
to the extent  permitted by Section 416 of the Code. In determining  whether the
Plan is a Top-Heavy  Plan,  the  provisions  of Section 416 of the Code shall be
applied.

      15.4 Minimum  Vesting:  For any Plan Year in which the Plan is a Top-Heavy
Plan,  each  Participant who is credited with at least one Hour of Service on or
after the date the Plan becomes a Top-Heavy Plan shall have his vested  interest
in his account attributable to Employer Contributions determined as follows:

  Years of Vesting Service    Vested Interest

      less than 2                    0%
      2 but less than 3             20%
      3 but less than 4             50%
      4 but less than 5             75%
      5 or more                    100%

      If in any subsequent  Plan Year,  the Plan ceases to be a Top-Heavy  Plan,
the above vesting schedule shall continue to apply.

      15.5 Minimum Contribution:  The aggregate Employer Contributions allocable
to the account of each  Employee  (other than a Key  Employee) who has satisfied
the  eligibility  requirements  of Paragraph 3.1,  whether or not a Contributing
Participant in the Plan, and who is in Service at the end of the Plan Year shall
not be less  than  the  lesser  of (i) 3% of such  Employee's  compensation  (as
defined in Section  414(s) of the Code or to the extent  required by the Code or
the  Regulations,  Section  1.415-2(d) of the  Regulations)  or (ii) the largest
percentage of Employer Contributions, as a percentage of Compensation, allocated
to the  accounts  of any Key  Employee  for such  Plan  Year.  For  purposes  of
determining  the percentage  under clause (ii), all defined  contribution  plans
required  to be included  in an  Aggregation  Group shall be treated as a single
plan. Clause (ii) shall not be applicable if the Plan is required to be included
in an Aggregation Group which enables a defined benefit plan also required to be
included in said Aggregation  Group to satisfy Sections  401(a)(4) or 410 of the
Code.  Any  required  minimum   contribution  shall  be  made  even  though  the
Participant would not be eligible otherwise to receive a contribution,  or would
have  received  a lesser  contribution  in such  Plan  Year as a  result  of the
Participant's  failure to make Basic  Contributions to the Plan. For the purpose
of clarity and without  limiting the scope of the  preceding  provisions of this
paragraph,  with respect to Plan Years  beginning  after  December 31, 1988, any
elective deferral (described in Section 402(g)(3) of the Code) under the Plan or
any other defined  contribution  plan that is aggregated with the Plan under the
provisions  stated above on behalf of any  Participant who is not a Key Employee
shall not be treated as Employer  Contributions  for purposes of this paragraph,
but will be treated as an Employer  Contribution for purposes of determining the
percentage at which  Employer  Contributions  are made for the Key Employee with
the highest percentage.

      15.6 Maximum Benefit and Contribution  Limitations:  If for any Limitation
Year the Plan is a Top-heavy  Plan,  then for  purposes of applying  the overall
limitations on benefits and  contributions  under Paragraph 14.4(a) of the Plan,
"1.0" shall be substituted for "1.25" in each applicable  place in subparagraphs
14.4(b)(1)  and  14.4(b)(2) of the Plan unless the Plan would not be a Top-Heavy
Plan if 90% were  substituted for 60% in each applicable place in Section 416(g)
of the Code and 4% were substituted for 3% in each applicable place in Paragraph
15.6 of the Plan.

      15.7  Coordination  of Plans:  If, with respect to a Non-Key  Employee who
benefits  in a Plan Year  under both a defined  contribution  plan and a defined
benefit  plan which are  determined  to be  Top-Heavy  Plans  maintained  by the
Employer,  a top-heavy  minimum benefit is not provided for such Plan year under
both  plans,  then  such  determination  for  such  Plan  Year  shall be made in
conformity  with the  comparability  analysis  described  in Q&A M-12 of Section
1.416-1 of the Regulations.

      Such  analysis  shall be modified,  where a factor of 1.25 is utilized for
such Plan Year in connection with the  satisfaction of the limitations set forth
in Section 415(e) of the Code, in accordance  with the last sentence of Q&A M-14
of Section 1.416-1 of the Regulations.



                                     XV-1




                                  ARTICLE XVI

                              GENERAL PROVISIONS

      16.1 Employment Relationships. Nothing contained herein shall be deemed to
give any  Employee the right to be retained in the service of any Employer or to
interfere with the right of an Employer to discharge any Employee at any time.

      16.2 Benefits  Provided Solely From Trust:  All benefits payable under the
Plan shall be paid or provided  for solely from the Trust;  no Employer  assumes
any liability or responsibility therefor.

      16.3  Non-Alienation  of Benefits.  Except as otherwise may be required by
law or  pursuant  to the terms of a  "qualified  domestic  relations  order," no
amount  payable  under the Plan shall be subject in any manner to  anticipation,
alienation, sale, transfer, assignment, pledge, encumbrance,  charge or seizure.
Except with respect to any indebtedness owing to the Trust by a Participant or a
Beneficiary,  no amount payable under the Plan shall be liable in any manner for
or subject to the debts,  contracts,  liabilities,  engagements  or torts of any
Employee  or  Beneficiary.  For  purposes  of the Plan,  a  "qualified  domestic
relations order" means any judgment,  decree, or order (including  approval of a
property  settlement  agreement) which has been determined by the Committee,  in
accordance  with  procedures  established  by it,  to  constitute  a  "qualified
domestic  relations  order" ("QDRO") within the meaning of Section 414(p) of the
Code.  The  Committee  shall comply with the terms and  provisions  of any order
which  requires  distribution  to an  alternate  payee  prior  to  the  affected
Participant's  "earliest  retirement  age," as such term is  defined  in Section
206(d)(3)(E)(ii)  of the Act and Section  414(p)(4)(B) of the Code, if the order
would  have  been  determined  to be  valid  QDRO  if  the  order  had  required
distribution at or after the  Participant's  "earliest  retirement date." If the
Committee receives notice that a domestic relations order that is intended to be
a QDRO is being prepared and will be provided to the Committee within 30 days or
such other short time as the Committee deems reasonable, the Committee may put a
temporary  hold on the  distribution  of benefits under the Plan to the affected
Participant,  pending (a) the determination of whether such order is a QDRO, and
(b) the rights of the alternate payee under such order.

      16.4 Merger,  Consolidation  or Transfer of Assets or Liabilities.  In the
event of any merger or consolidation  with, or transfer of assets of the Plan to
another  plan,  each  Participant  in the Plan  shall  receive a benefit  in the
surviving plan (if such plan were then terminated) at least equal to the benefit
which  he  would  have  been  entitled  to  receive  immediately  prior  to  the
transaction if the Plan had then terminated.

      16.5 Payments to Minors and Incompetents.  If a Participant or Beneficiary
entitled to receive any  benefits  hereunder  is deemed by the  Committee  or is
adjudged to be legally  incapable of giving valid receipt and discharge for such
benefits or is a minor,  such benefit shall be paid to such person or persons as
the Committee may designate or to a duly appointed guardian.

      16.6  Employee's  Records.   Each  of  the  Employers  and  the  Committee
respectively shall keep such records, and shall give the other reasonable access
to such  information  as is necessary or desirable to effectuate the purposes of
the Plan and the Trust including,  without  limiting the foregoing,  records and
information  with respect to the employment  date, date of  participation in the
Plan  and  Compensation  of  Employees,  elections  by  Participants  and  their
Beneficiaries  and consents granted and  determinations  made under the Plan and
the  Trust.  Neither  the  Employers  nor the  Committee  shall be  required  to
duplicate any records kept by the other.

      16.7 Missing  Persons.  Each  Participant and  Beneficiary  shall keep the
Committee advised of his current address. If amounts become  distributable under
the Plan and the Committee is unable,  after reasonable  efforts,  to locate the
Participant or Beneficiary to whom  distribution  is payable for a period of two
years from the time such  distribution  first becomes payable,  all such amounts
shall be  forfeited  and  applied  in  accordance  with  Paragraph  5.4.  If the
Participant  or  his  Beneficiary   thereafter  applies  for  the  Participant's
distributable  account,  the amount  forfeited  shall be paid to him pursuant to
Article IX.

      16.8  Severability  of  Provisions.  If any  provision of the Plan is held
invalid or unenforceable,  such invalidity or unenforceability  shall not affect
any other  provisions,  and the Plan shall be construed  and enforced as if such
provision had not been included.

      16.9 Receipt and Release.  As a condition  precedent to the payment to any
Participant or to his legal  representative  or Beneficiary,  such  Participant,
legal  representative  or  Beneficiary  may be  required  to  execute  a receipt
therefor and a release in such form as shall be determined by the Committee.

      16.10  Fiduciary  Capacities.  Any person or group of persons may serve in
more than one fiduciary capacity with respect to the Plan.

      16.11  Titles  and  Headings.  The  titles to  Articles  and  headings  of
Paragraphs of the Plan are for  convenience  of reference.  In case of conflict,
the text of the Plan, rather than such titles and headings, shall control.

      16.12 Gender and Number.  Wherever used herein, the masculine gender shall
include the feminine  gender and the singular  shall include the plural,  unless
the context indicates otherwise.

      16.13  Governing  Law.  To the  extent  that New  Jersey  law has not been
preempted by federal law,  the  provisions  of the Plan shall be governed by and
construed in accordance with the laws of the State of New Jersey.

      16.14 Counterparts:  If this Agreement is executed,  it may be executed in
two or more  counterparts,  each of which shall be deemed an original and all of
which together shall constitute one and the same instrument.

                                                                   EXHIBIT 10.40

                      INTERCORPORATE SERVICES AGREEMENT

      This INTERCORPORATE SERVICES AGREEMENT (the "Agreement"),  effective as of
January 1, 1996,  amends and  supersedes  that certain  Intercorporate  Services
Agreement effective as of January 1, 1995 by and between VALHI, INC., a Delaware
corporation ("Valhi"), and NL INDUSTRIES, INC., a New Jersey corporation ("NL").

                                   Recitals

            Employees  and  agents  of Valhi  and  affiliates  of Valhi  perform
management,  financial  and  administrative  functions  for  NL  without  direct
compensation from NL.

            NL does not  separately  maintain the full  internal  capability  to
perform all necessary management, financial and administrative functions that NL
requires.

            Valhi desires to have the services of certain personnel of NL and NL
is willing to provide such services under the terms of this Agreement.

            The  cost of  maintaining  the  additional  personnel  necessary  to
perform the  functions  provided for by this  Agreement  would exceed the amount
charged to such party that is contained in the net fee set forth in Section 4 of
this  Agreement and that the terms of this  Agreement  are no less  favorable to
each party than could  otherwise be obtained  from a third party for  comparable
services.

            Each party desires to continue  receiving the management,  financial
and  administrative  services  presently  provided  by the  other  party and its
affiliates  and each party is willing to continue to provide such services under
the terms of this Agreement.

                                  Agreement

      For and in  consideration  of the  mutual  premises,  representations  and
covenants herein contained, the parties hereto mutually agree as follows:

      Section Valhi  Services to be Provided.  Valhi agrees to make available to
NL, upon request,  the following  services (the "Valhi Services") to be rendered

                  Consultation   and   assistance   in   the   development   and
      implementation   of  NL's  corporate   business   strategies,   plans  and
      objectives;

                  Consultation  and  assistance  in  management  and  conduct of
      corporate affairs and corporate governance consistent with the charter and
      bylaws of NL;

                  Consultation   and  assistance  in  maintenance  of  financial
      records  and  controls,  including  preparation  and  review  of  periodic
      financial  statements  and reports to be filed with public and  regulatory
      entities and those required to be prepared for financial  institutions  or
      pursuant to indentures and credit agreements;








                  Consultation   and  assistance  in  cash   management  and  in
      arranging financing necessary to implement the business plans of NL;

                  Consultation    and   assistance   in   tax   management   and
      administration,  including, without limitation,  preparation and filing of
      tax returns, tax reporting, examinations by government authorities and tax
      planning; and

                  Such other  services  as may be  requested  by NL from time to

                  The services of Joseph S. Compofelice to act as Executive Vice
      President of Valhi,  which Valhi and NL agree shall involve  substantially
      such  time as has  been  allocated  in the  past  and is  currently  being
      devoted;

                  The  services of NL's  internal  audit  personnel in providing
      consultation  and  assistance in  performing  internal  audit  projects as

with routine management,  financial and administrative  functions related to the
ongoing  operations  of the  Receiving  Party and not with  respect  to  special
projects,  including corporate investments,  acquisitions and divestitures.  The

adjusted  for  internal  corporate  growth  or  contraction,  but not for  major
corporate acquisitions or divestitures,  and that adjustments may be required to
the terms of this Agreement in the event of such major  corporate  acquisitions,
divestitures or special projects. Each Receiving Party will continue to bear all
other costs  required for outside  services  including,  but not limited to, the
outside services of attorneys, auditors, trustees, consultants,  transfer agents
and registrars, and it is expressly understood that each Providing Party assumes

Agreement to be provided by such party.  In addition to the amounts charged to a
Receiving Party for Services provided pursuant to this Agreement, such Receiving
Party will pay the Providing Party the amount of out-of-pocket costs incurred by
the Providing Party in rendering such Services.

      Section  Net  Fee for  Services.  Valhi  agrees  to pay to NL a net fee of
$2,500 quarterly,  commencing as of January 1, 1996, pursuant to this Agreement,
which net fee  includes  reimbursements  of  $36,000  for  certain  NL  Services
provided in 1995. In addition to the net fee:

                  Valhi shall pay to NL an  additional  amount  equal to the sum
of:

            NL's  internal  auditors  to  providing  NL  Services  described  in
            Subsection  2(b) and (z) the number of internal  auditors  providing

1996.

      Section   Extensions.    This   Agreement   shall   be   extended   on   a
quarter-to-quarter  basis  after the  expiration  of its  original  term  unless
written  notification is given by Valhi or NL thirty (30) days in advance of the
first day of each successive  quarter or unless it is superseded by a subsequent
written agreement of the parties hereto.

      Section  Limitation of Liability.  In providing Services  hereunder,  each
Providing  Party shall have a duty to act,  and to cause its agents to act, in a
reasonably  prudent manner,  but no Providing  Party nor any officer,  director,
employee  or agent of such  party  nor or its  affiliates  shall be  liable to a
Receiving  Party for any error of  judgment  or  mistake  of law or for any loss
incurred  by the  Receiving  Party in  connection  with the matter to which this
Agreement relates,  except a loss resulting from willful misfeasance,  bad faith
or gross negligence on the part of the Providing Party.

      Section  Indemnification.  Each Receiving  Party shall  indemnify and hold
harmless the Providing  Party,  its  affiliates and their  respective  officers,
directors  and  employees  from and  against  any and all  losses,  liabilities,

expenses of litigation) to which such Providing Party may become subject arising

                      INTERCORPORATE SERVICES AGREEMENT

      This INTERCORPORATE SERVICES AGREEMENT (the "Agreement"),  effective as of
January 1, 1996,  amends and  supersedes  that certain  Intercorporate  Services
Agreement effective as of January 1, 1995 by and between CONTRAN CORPORATION,  a
Delaware  corporation  ("Contran"),  and  NL  INDUSTRIES,  INC.,  a  New  Jersey
corporation.
("Recipient"),

                                   Recitals

            Harold C.  Simmons,  an employee  of Contran and a director  and the
Chairman of the Board of  Recipient,  performs  certain  advisory  functions for
Recipient,  which  functions are unrelated to his function as a director and the
Chairman of the Board of Recipient, without direct compensation from Recipient.

            Recipient does not separately  maintain the full internal capability
to perform all necessary advisory functions that Recipient requires.

            The cost of engaging the advisory services of someone possessing Mr.
Simmons'  expertise  and the cost of  maintaining  the  personnel  necessary  to
perform the functions  provided for by this  Agreement  would exceed the fee set
forth in Section 3 of this Agreement and the terms of this Agreement are no less
favorable to Recipient  than could  otherwise be obtained from a third party for
comparable services.

            Recipient  desires to continue  receiving  the advisory  services of
Harold C.  Simmons and Contran is willing to continue to provide  such  services
under the terms of this Agreement.

                                  Agreement

      For and in  consideration  of the  mutual  premises,  representations  and
covenants herein contained, the parties hereto mutually agree as follows:

      Section  Services to be  Provided.  Contran  agrees to make  available  to
Recipient,  upon request, the following services (the "Services") to be rendered
by Harold C. Simmons:

                  Consultation   and   assistance   in   the   development   and
      implementation of Recipient's  corporate  business  strategies,  plans and
      objectives; and

                  Such other services as may be requested by Recipient from time
to time.

This  Agreement  does not apply to and the  Services  provided for herein do not
include any services that Harold C. Simmons may provide to Recipient in his role
as a director on  Recipient's  Board of Directors,  as Chairman of such Board of
Directors or any other activity related to such Board of Directors.








Section  Miscellaneous  Services.  It is the intent of the  parties  hereto that
Contran  provide only the Services  requested  by Recipient in  connection  with
routine  functions  related to the ongoing  operations of Recipient and not with
respect to special projects,  including corporate investments,  acquisitions and
divestitures.  The parties  hereto  contemplate  that the  Services  rendered in
connection with the conduct of Recipient's  business will be on a scale compared
to that existing on the effective date of this Agreement,  adjusted for internal
corporate  growth or contraction,  but not for major  corporate  acquisitions or
divestitures,  and  that  adjustments  may be  required  to the  terms  of  this
Agreement in the event of such major  corporate  acquisitions,  divestitures  or
special  projects.  Recipient will continue to bear all other costs required for
outside  services  including,  but not  limited  to,  the  outside  services  of
attorneys, auditors, trustees, consultants,  transfer agents and registrars, and
it is expressly understood that Contran assumes no liability for any expenses or
services  other than those  stated in Section 1. In  addition to the fee paid to

original  term of this  Agreement  shall be from January 1, 1996 to December 31,
1996.

      Section   Extensions.    This   Agreement   shall   be   extended   on   a
quarter-to-quarter  basis  after the  expiration  of its  original  term  unless
written  notification  is given by  Contran  or  Recipient  thirty  (30) days in
advance of the first day of each  successive  quarter or unless it is superseded
by a subsequent written agreement of the parties hereto.

      Section  Limitation  of Liability.  In providing  its Services  hereunder,
Contran  shall  have a duty  to act,  and to  cause  its  agents  to  act,  in a
reasonably  prudent  manner,  but  neither  Contran nor any  officer,  director,
employee or agent of Contran or its affiliates  shall be liable to Recipient for
any error of judgment or mistake of law or for any loss incurred by Recipient in
connection  with the  matter  to which  this  Agreement  relates,  except a loss
resulting from willful misfeasance, bad faith or gross negligence on the part of
Contran.

      Section Indemnification of Contran by Recipient. Recipient shall indemnify
and hold  harmless  Contran,  its  affiliates  and  their  respective  officers,
directors  and  employees  from and  against  any and all  losses,  liabilities,
claims,  damages,  costs  and  expenses  (including  attorneys'  fees and  other
expenses of litigation)  to which such party may become  subject  arising out of
the Services  provided by Contran to  Recipient  hereunder,  provided  that such
indemnity  shall not protect  any person  against  any  liability  to which such
person would otherwise be subject by reason of willful misfeasance, bad faith or
gross negligence on the part of such person.

      Section  Further  Assurances.  Each of the  parties  will  make,  execute,
acknowledge and deliver such other instruments and documents,  and take all such
other actions,  as the other party may reasonably  request and as may reasonably
be required in order to effectuate  the purposes of this  Agreement and to carry
out the terms hereof.

      WHEREAS,  Tremont desires that NL provide certain services to Tremont, and

            a.    certain administration and management services with respect to
                  Tremont's insurance and risk management needs, including:

                  (i)  management of claims (including insured
                       and self-insured workers compensation and
                       liability claims);
                  (ii) budgeting and related activities;
                  (iii)administration of Tremont's captive

                  (iv) coordination of property loss control
                       program; and
                  (v)  administration of Tremont's insurance program,  excluding
                       all employee benefit and welfare related programs.

            b.    certain administration and management services with respect to
                  Tremont's real properties and interests.

            c.    consultation and assistance in performing internal audit
                  projects, as requested.

            d.    certain executive secretarial and administrative services.

      2. Fees for Services and  Reimbursement of Expenses.  Tremont shall pay to
NL an annual fee of $88,400  (the "Annual  Fee") for the  Services  described in
paragraphs 1.a, 1.b , and 1.d above payable in quarterly installments of $22,100
during the term of this Agreement plus all  out-of-pocket  expenses  incurred in
connection with the performance of such Services. In addition,  Tremont will pay
to NL within  thirty  (30) days after  receipt of an invoice  (such  invoices to
occur no more frequently than once per month)

                                      1

by NL's internal auditors to providing Services described in paragraph 1.c above
times  the  number  of  internal  auditors  providing  such  Services  plus  all
out-of-pocket  expenses incurred in the performance of such Services;  provided,
however, in the event that Tremont determines,  in its sole discretion,  that it
no  longer  desires  certain  of the  Services  or NL  determines,  in its  sole
discretion,  that it no longer desires to provide certain of the Services,  then
Tremont or NL, as appropriate,  shall provide the other party with a ninety (90)
day  prior  written  notice  of  cancellation  describing  the  Services  to  be
terminated  or  discontinued  and Tremont and NL during such  ninety-day  period
shall  agree  to a  pro-rata  reduction  of the  fees  due  hereunder  for  such
terminated or discontinued Services.

      3. Limitation of Liability. In providing Services hereunder, NL shall have
a duty to act, and to cause its agents to act, in a reasonably  prudent  manner,
but  neither  NL nor any  officer,  director,  employee  or agent of NL shall be
liable to Tremont or its  subsidiaries  for any error of  judgment or mistake of
law or for any loss incurred by Tremont or its  subsidiaries  in connection with
the  matters to which  this  Agreement  relates,  except a loss  resulting  from
willful  misfeasance,  bad faith or gross  negligence  on the part of NL or from
NL's reckless disregard of obligations and duties under this Agreement.

      4.  Indemnification  of NL by Tremont.  Tremont  shall  indemnify and hold
harmless NL, its  subsidiaries  and their  respective  officers,  directors  and
employees  from and against any and all losses,  liabilities,  claims,  damages,
costs and expenses (including  reasonable  attorneys' fees and other expenses of
litigation) to which such party may become subject  arising out of the provision
by NL to Tremont and its subsidiaries of any of the Services, provided that such
indemnity  shall not protect any such party  against any liability to which such
person would otherwise by subject by reason of willful  misfeasance,  bad faith,
gross negligence or reckless disregard of obligations and duties hereunder.

      5. Further Assurance. Each of the parties will make, execute,  acknowledge
and  deliver  such  other  instruments  and  documents,  and take all such other
actions,  as the other party may  reasonably  request and as may  reasonably  by
required in order to effectuate  the purposes of this Agreement and to carry out
