                                    PART I

ITEM 1.     BUSINESS

General

      NL  Industries,  Inc.,  organized  as a New  Jersey  corporation  in 1891,
conducts  its   continuing   operations   through  its  principal   wholly-owned
subsidiary,  Kronos,  Inc. In January 1998 the specialty  chemicals  business of
Rheox,  Inc.,  a  wholly-owned  subsidiary  of NL, was sold for $465  million to
Elementis plc,  including $20 million  attributable to a five-year  agreement by
the Company not to compete in the rheological  products  business.  See "Rheox -
discontinued  operations"  for related  discussion.  At December 31, 1997 Valhi,
Inc. and Tremont Corporation,  each affiliates of Contran Corporation,  held 57%
and 18%,  respectively,  of NL's  outstanding  common stock, and together may be
deemed to control the Company.  At December 31, 1997 Contran and other  entities
related  to Harold C.  Simmons  held  approximately  93% of  Valhi's  and 49% of
Tremont's  outstanding common stock.  Substantially all of Contran's outstanding
voting stock is held by trusts  established for the benefit of certain  children
and  grandchildren of Mr. 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  12% share of  worldwide  TiO2 sales volume in 1997.
Approximately  one-half of Kronos' 1997 sales volume was in Europe, where Kronos
is the second largest producer of TiO2.

      The Company's  objective is to maximize total  shareholder  returns by (i)
focusing on continued cost control,  (ii) acquiring  additional  TiO2 production
capacity, (iii) investing in certain cost effective  debottlenecking projects to
also  increase  TiO2  production  capacity and  productivity  and (iv)  reducing
outstanding indebtedness.

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 gross  domestic  product in
various regions of the world.

      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 increased during
the last

                                    -1-





three  quarters  of 1997,  following a downturn in prices that began in the last
half of 1995. The Company  expects TiO2 prices will continue to increase  during
1998 as the impact of  announced  price  increases  take  effect.  Industry-wide
demand for TiO2  continued to grow in 1997, and Kronos' record 1997 sales volume
was 10% higher than the previous record set in 1996. The Company's  expectations
as to the  future  prospects  of the TiO2  industry  and prices are based upon a
number of factors beyond the Company's control,  including  continued  worldwide
growth of gross domestic product, competition in the market place, unexpected or
earlier-than-expected  capacity additions and technological  advances. If actual
developments  differ  from the  Company's  expectations,  industry  and  Company
performance could be unfavorably affected.

      Kronos has an  estimated  18% share of European  TiO2 sales  volume and an
estimated 13% 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  region for TiO2 consumption could emerge in Eastern Europe,
the Far East or 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  consumption of TiO2 in Eastern  Europe.
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  changed  anticipated TiO2 consumption over the
past decade  because  extenders  generally  have,  to date,  failed to match the
performance  characteristics of TiO2. As a result, 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

                                    -2-





service of its  products  in  domestic  and  international  markets.  By volume,
approximately  one-half of Kronos'  1997 TiO2 sales were to Europe,  with 36% 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 described below),  and
the manufacture and sale of iron-based water treatment  chemicals  (derived from
co-products of the 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 1997 represented almost 60% of industry capacity.

      Kronos produced a record 408,000 metric tons of TiO2 in 1997,  compared to
373,000  metric tons produced in 1996 and 393,000  metric tons in 1995.  Kronos'
production  rates were  increased to near full  capacity in late 1996 and Kronos
maintained near full capacity  production  rates  throughout 1997 in response to
strong demand. Kronos believes its current annual attainable production capacity
is  approximately  420,000 metric tons,  including its one-half  interest in the
joint  venture-owned  Louisiana plant (see "TiO2  manufacturing joint venture").
Kronos substantially  completed a $34 million  debottlenecking  expansion of its
Leverkusen,  Germany  chloride-process  plant  in 1997  which  increased  annual
production capacity by approximately 20,000 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,  South 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)  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 also expires in 2000.  Raw materials  purchased
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  extensions  to  existing  long-term  supply
contracts prior to the expiration of the contracts.

                                    -3-





      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
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 rock ilmenite mine in Norway which
provided  all of Kronos'  feedstock  for its  European  sulfate-process  pigment
plants in 1997. For its Canadian plant, Kronos also purchases sulfate grade slag
from  Q.I.T.-Fer et Titane Inc. under a long-term  supply contract which expires
in 2002.

      Kronos believes the availability of titanium-containing feedstock for both
the  chloride and sulfate  processes  is adequate  for the next  several  years.
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 certain  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. ("Tioxide"), a wholly-owned
subsidiary of Imperial Chemicals Industries plc ("ICI"), each own a 50%-interest
in a manufacturing  joint venture,  Louisiana Pigment Company ("LPC").  LPC 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.  ICI has agreed to sell
Tioxide's  non-North  American  operations  to E.I.  du Pont  de  Nemours  & Co.
("DuPont"), subject to regulatory approval. ICI has announced it intends to sell
Tioxide's 50% interest in LPC and its remaining  North American  operations in a
separate  transaction.  The Company has advised ICI of its interest in acquiring
the portion of LPC it does not currently own.

      A  supervisory  committee,  composed  of four  members,  two of  whom  are
appointed by each  Partner,  directs the  business and affairs of LPC  including
production  and output  decisions.  Two  general  managers,  one  appointed  and
compensated  by each Partner,  manage the 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.


                                    -4-





  Competition

      The TiO2 industry is highly competitive. During the early 1990s, supply of
TiO2 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 and  throughout  1997,  and selling
prices  of TiO2  began to  increase  during  the last  three  quarters  of 1997.
Additional  price  increases have been  announced by most major TiO2  producers,
including Kronos,  that are expected to be implemented  during the first half of
1998, and which Kronos expects to favorably impact operating income  comparisons
in 1998 versus 1997. No assurance can be given that price trends will conform to
the Company's expectations.  See "Industry" for the Company's views of risks and
uncertainties within the TiO2 industry.

      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
three to five 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.
During 1997 Kronos had an estimated  12% share of worldwide  TiO2 sales  volume,
and  Kronos  believes  that it is the  leading  seller  of TiO2 in a  number  of
countries, including Germany and Canada.

      Kronos'  principal  competitors  are  DuPont;  ICI  (Tioxide);  Millennium
Chemicals, Inc. (Millennium Inorganic Chemicals,  Inc.); Kerr-McGee Corporation;
Kemira Oy; Ishihara Sangyo Kaisha,  Ltd.; and Bayer AG. These seven  competitors
have estimated individual shares of TiO2 production capacity ranging from 23% to
4%, and an estimated  aggregate 74% share of worldwide TiO2  production  volume.
DuPont has about one-half of total U.S. TiO2 production  capacity and is Kronos'
principal North American competitor.

      In July 1997 DuPont  announced  an  agreement  had been reached to acquire
Tioxide's TiO2 business in Europe, Asia and Africa, that it expects to close in

                                    -5-





early 1998 subject to regulatory approval.  In January 1998 Kerr-McGee announced
an  agreement to acquire  approximately  80% of the  European  TiO2  business of
Bayer.

Rheox - discontinued operations

      On January 30, 1998 the specialty  chemicals business of Rheox was sold to
Elementis plc (formerly known as Harrisons and Crosfield, plc) for $465 million,
including $20 million  attributable to a five-year  agreement by the Company not
to compete in the rheological  products  business.  As a result of the sale, the
Company has reported its Rheox operation as discontinued  operations.  Following
the sale, Rheox, Inc. was renamed NL Capital Corporation. The Company intends to
use the  after-tax  proceeds  of about  $400  million  primarily  to  invest  in
additional TiO2 production capacity and reduce its outstanding indebtedness.

Research and Development

      The  Company's  expenditures  for  research  and  development  and certain
technical support programs,  excluding  discontinued  operations,  have averaged
approximately  $8 million  annually  during the past three  years.  Research and
development  activities  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.

Patents and Trademarks

      Patents  held for  products and  production  processes  are believed to be
important to the Company and to the  continuing  business  activities of Kronos.
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.

      The  Company's  major  trademarks,   including  Kronos  and  Titanox,  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.   Approximately   three-quarters   of  the  Company's  1997
consolidated  sales,  excluding  discontinued   operations,   were  to  non-U.S.
customers,  including  13% to  customers  in areas other than Europe and Canada.
Sales to customers in Asia accounted for 5% of consolidated  net sales.  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

                                    -6-





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
generally higher in the second and third calendar quarters than in the first and
fourth calendar quarters.

Employees

      As of December 31, 1997 the Company employed  approximately 2,600 persons,
excluding  the  joint  venture  employees  and  discontinued  operations,   with
approximately  100  employees in the United  States and  approximately  2,500 at
sites  outside the United  States.  Hourly  employees in  production  facilities
worldwide,  including the TiO2 manufacturing 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.


                                    -7-





      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 the  Louisiana  plant owned and operated by the
joint venture is in substantial compliance with applicable requirements of these
laws or compliance orders issued thereunder. Following the sale of its specialty
chemicals business,  the Company has no U.S. plants other than LPC. 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
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  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 advance 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 respect to treatment
of effluent from the Leverkusen plant.

      In order to reduce sulfur dioxide emissions into the atmosphere consistent
with applicable environmental regulations,  Kronos completed the installation of
off-gas desulfurization systems in 1997 at its Norwegian and German plants at an
estimated cost of $30 million.  The  manufacturing  joint venture  completed the
installation  of a $16 million off-gas  desulfurization  system at the Louisiana
plant in 1996.

      The Company's capital  expenditures  related to its ongoing  environmental
protection and improvement  programs are currently  expected to be approximately
$5 million in each of 1998 and 1999.


                                    -8-





      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 liens on it
that  secure  claims  by the  City of  Leverkusen  and the  German  federal  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. 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.

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
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

                                    -9-





manufacturers  have  been  successful.  Examples  of such  proposed  legislation
include  bills which would  permit civil  liability  for damages on the basis of
market share,  rather than  requiring  plaintiffs to prove that the  defendant's
product caused the alleged damage. While 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 imposition of market share liability could have such an effect.  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 and have been inactive
since 1992,  Hall v. HANO,  et al. (No.  89-3552) and Allen V. HANO, et al. (No.
89-427) Civil District Court for the Parish of Orleans, State of Louisiana.

      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. In May 1993 the Appellate Division of the Supreme Court affirmed the

                                    -10-





denial  of  the   motion  to  dismiss   plaintiffs'   fraud,   restitution   and
indemnification  claims.  In May 1994 the trial court  granted  the  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. 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.  In July 1997 the denial of defendants' two summary  judgment
motions on the fraud claim were affirmed by the Appellate Division. Discovery is
proceeding.

      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.

      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'

                                    -11-





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 and in October 1997 the Maryland  Special Court of
Appeals affirmed. Plaintiffs did not seek further review of the dismissal of the
conspiracy claims against the Company and other defendants.  Plaintiffs' request
for review of the  affirmance of the dismissal of the remaining  defendants  was
denied by the Maryland Court of Appeals in February 1998.

      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 alleged  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.  In May 1997 plaintiffs moved for class  certification and defendants
moved for summary  judgment.  In June 1997 the Court stayed all further activity
in the case pending  reconsideration  of its 1995 decision  permitting filing of
the  complaint  against  the  manufacturer  defendants  and  joinder  of the new
complaint  with the  pre-existing  complaint  against  New York  City and  other
landlords.

      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,  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 plaintiff has lived since 1977.
In July 1996 the Company  filed an answer  denying  plaintiff's  allegations  of
wrongdoing and liability.  In November 1997 plaintiffs  dismissed this case with
prejudice as to all defendants.

      In April 1997 the  Company  was served  with a  complaint  in Parker v. NL
Industries,  et al.  (Circuit  Court,  Baltimore  City,  Maryland,  No. 97085060
CC915).  Plaintiff,  now an adult, and his wife, seek  compensatory and punitive
damages from the Company,  another former manufacturer of lead paint and a local
paint retailer,  based on claims of negligence,  strict liability and fraud, for
plaintiff's alleged ingestion of lead paint as a child. In June 1997 the Company
answered the complaint denying  liability.  In February 1998 the Court dismissed
the fraud claim. The case is set for trial in July 1998.


                                    -12-





      In January 1998 the Company was served with an amended  complaint in Adams
v. NL Industries,  Inc., et at., (No. A9701785), Court of Common Pleas, Hamilton
County,  Ohio,  alleging  injury to a minor arising out of exposure to lead, and
seeking  compensatory  and punitive  damages from the Company,  and other former
manufacturers of lead products and the LIA based on claims of negligence, strict
liability,  breach of  warranty,  failure to warn,  and  nuisance.  The  amended
complaint also asserts various claims against plaintiff's  landlord. In February
1998 the Company filed a motion to dismiss the action on procedural  grounds. In
March  1998  plaintiffs  informed  the Court  that they  intend to  dismiss  the
complaint.

      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  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

                                    -13-





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.

      In June  1997 the  Company  reached a  settlement  in  principle  with its
insurers  regarding  allocation  of defense  costs in the lead pigment  cases in
which reimbursement of defense costs had been sought.

      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. Nor has the Court 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,  and/or
damages for injury to natural  resources.  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, 1997 the Company had accrued  $135
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 was
increased  by $30 million 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

                                    -14-





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  $175 million.  The Company's
estimate of such  liability  has not been  discounted  to present  value and the
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.

      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,  Illinois  lead  smelter  formerly  owned by the
Company.  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.  The
Company  presently is challenging  portions of the U.S.  EPA's  selection of the
remedy. In September 1997 the U.S. EPA informed the Company that past and future
cleanup  costs are  estimated to total  approximately  $63.5  million.  There is
currently no allocation among the PRPs for these costs.

      At the  Pedricktown,  New Jersey lead smelter site  formerly  owned by the
Company the U.S. EPA has 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 January 1998 the Company and the other PRPs were
informed  that U.S.  EPA  would  begin  negotiations  in 1998  with  respect  to
performance of the remedial action phase of operable unit one. In addition,  the
U.S. EPA has indicated that it has incurred approximately $6.2 million in past

                                    -15-





costs.  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.

      Having completed the RIFS at the Company's  former  Portland,  Oregon lead
smelter site, 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.  In May 1997 the
U.S.  EPA issued an Amended  Record of Decision  ("ARD") for the soils  operable
unit  changing  portions  of the  cleanup  remedy  selected.  The  ARD  requires
construction of an onsite  containment  facility estimated to cost between $10.5
million and $12 million,  including  capital costs and operating and maintenance
costs.  The Company and certain other PRPs have entered into a consent decree to
perform  the  remedial  action in the ARD. 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. In February 1998 the Company and the
other  defendants  reached an agreement in principle to settle the litigation by
agreeing  to pay a portion of future  costs,  which are  estimated  to be within
previously-accrued amounts.

      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.  In August  1997 the U.S.  EPA issued the record of
decision for the Baxter Springs and Treece subsites.  The U.S. EPA has estimated
that the selected  remedy will cost an aggregate of  approximately  $7.1 million
for both subsites  ($5.4 million for the Baxter Springs  subsite).  In addition,
the Company  received a notice in March 1998 from the U.S.  EPA that it may be a
PRP in three additional subsites in Cherokee County.

      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

                                    -16-





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  reinstate  the
complaint,  and dismissed the case with prejudice.  In November 1996 the appeals
court reversed the dismissal. In August 1997 the trial court again dismissed the
case and the state has appealed. 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.

      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 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,  which was
declined.  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.

      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 $1.8 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

                                    -17-





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
February 1998 the parties  reached  agreement in principle to settle this matter
within previously-accrued amounts.

      At a municipal and industrial  waste  disposal site in Batavia,  New York,
the Company and 50 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.  The  Company  and the  other  PRPs  have
completed the work comprising  operable unit two (the extension of the municipal
water supply) with the exception of annual operation and  maintenance.  The U.S.
EPA has also demanded approximately $.9 million in past costs from the PRPs.

  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.  An agreement  has been
reached  settling  this matter,  with the Company being  indemnified  by another
party.

      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 has reached an agreement to settle
this case.

      In March 1997 the Company was served with a complaint in Ernest Hughes, et
al. v. Owens-Corning Fiberglass, Corporation, et al., No. 97-C-051, filed in the
Fifth Judicial District Court of Cass County,  Texas, on behalf of approximately
4,000  plaintiffs and their spouses  alleging injury due to exposure to asbestos
and seeking  compensatory and punitive damages.  The Company has filed an answer
denying the material allegations. The case has been stayed, and the plaintiffs

                                    -18-





are  refiling  their  cases  in  Ohio.  The  Company  is  also  a  defendant  in
approximately  1,000  additional  asbestos  cases pending in Ohio,  the first of
which is scheduled for trial in the third quarter of 1998.

      Plaintiff brought the complaint in Frank D. Seinfeld v. Harold C. Simmons,
et al.  (Superior Court of New Jersey,  Bergen County,  Chancery  Division,  No.
C-336-96) in September 1996 on behalf of himself and derivatively,  on behalf of
the Company,  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.  In March 1998 Valhi reached an
agreement to settle this matter.  Under the stipulation of settlement,  in which
the  defendants  denied any  wrongdoing,  Valhi  would  transfer  to the Company
750,000  shares  of the  Company's  common  stock  held  by  Valhi,  subject  to
adjustment  based upon the market price of the  Company's  shares at the time of
closing,  up to a maximum  of  825,000  shares of the  Company  and a minimum of
675,000 shares of the Company.  Valhi may, at its option,  transfer cash or cash
equivalents  in lieu of all or a portion of such shares of the Company  based on
the market price of the  Company's  common  stock at the time of  transfer.  The
settlement  is subject  to,  among other  things,  approval by the court and, if
approved,  is expected to close in the second or third quarter of 1998. Pursuant
to the  agreement  and subject to court  approval,  the Company  will  reimburse
plaintiffs for attorneys' fees of up to $3 million and related costs.  There can
be no assurance that any such settlement will become effective.

      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.

      NL's common stock is listed and traded on the New York Stock  Exchange and
the  Pacific  Exchange  under the symbol  "NL." As of March 18,  1998 there were
approximately  8,000 holders of record of NL common stock.  The following  table
sets  forth the high and low sales  prices  for NL common  stock on the New York
Stock Exchange  ("NYSE")  Composite Tape. On March 18, 1998 the closing price of
NL common stock according to the NYSE Composite Tape was $16-3/8.

The Company's Senior Notes generally limit the ability of the Company to pay dividends and at December 31, 1997 no amounts were available for dividends. The Company paid three quarterly cash dividends during 1996 of $.10 per share, beginning with a dividend paid on March 1, 1996. The Company suspended its quarterly dividend in October 1996. The Company did not pay dividends in 1995 or 1997. The declaration and payment of future dividends and the amount thereof will be dependent upon the Company's results of operations, financial condition, contractual restrictions and other factors deemed relevant by the Company's Board of Directors. -20- ITEM 6.

(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, operating income or net income determined under generally accepted accounting principles ("GAAP") as an indicator of the Company's operating performance, or cash flows from operating, investing and financing activities determined under GAAP 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). -22- ITEM 7. MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS RESULTS OF OPERATIONS General The Company's continuing operations are conducted by Kronos in the TiO2 business segment. As discussed below, average TiO2 selling prices declined in 1996 and 1997 compared to the prior year, but average selling prices increased during each of the last three quarters of 1997 compared to the immediately preceding quarter. Kronos' operating income and margins declined during 1996, but improved in 1997. Many factors influence TiO2 pricing levels, including industry capacity, worldwide demand growth and customer inventory levels and purchasing decisions. 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 ------------------------ ---------------- 1995 1996 1997 1996-95 1997-96 ---- ---- ---- ------- ------- (In millions) Net sales - Kronos $894.1 $851.2 $837.2 -5% -2% Operating income - Kronos $161.2 $ 71.6 $ 82.5 -56% +15% Percent change in TiO2: Sales volume +6% +10% Average selling prices (in billing currencies) -9% -4%
Kronos' operating income for 1997 increased on record production and sales volumes and $12.9 million of income resulting from the refunds of German trade capital taxes related to prior years, offset by lower average TiO2 selling prices compared to 1996. In billing currency terms, Kronos' 1997 average TiO2 selling prices were 4% lower than in 1996. Average selling prices in the fourth quarter of 1997 were 10% higher than the fourth quarter of 1996 and were 5% higher than the third quarter of 1997. Selling prices at the end of 1997 were 12% higher than year-end 1996 levels, 7% higher than the average for 1997 and were 1% higher than the average selling prices for the fourth quarter of 1997. Kronos' operating income in 1996 was lower than 1995, primarily due to 9% lower average TiO2 selling prices, partially offset by higher sales volumes. Kronos' 1997 operating income includes $12.9 million of income resulting from German trade capital tax refunds related to prior years, including interest. The German tax authorities were required to remit refunds based on (i) recent court decisions which resulted in reducing the trade capital tax base and (ii) prior agreements between the Company and the German tax authorities regarding payment of disputed taxes. -23- Kronos' cost of sales in 1997 was lower than 1996 due to the favorable effects of foreign currency translation and lower unit costs, primarily due to higher production levels, partially offset by higher 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. As a percentage of net sales, cost of sales decreased in 1997 primarily due to lower unit costs and increased in 1996 primarily due to the impact on net sales of decreased average selling prices. Kronos' selling, general and administrative expenses declined in 1997 from the previous year due to favorable effects of foreign currency translation and German trade capital tax refunds, partially offset by higher distribution expenses associated with higher 1997 sales volumes, while 1996 expenses were lower than 1995 as a result of continuing cost containment efforts. Record sales volume of 427,000 metric tons of TiO2 in 1997 was 10% higher than 1996, with improvements in all major markets, including a 12% increase in Europe. Approximately one-half of Kronos' 1997 TiO2 sales, by volume, were attributable to markets in Europe with approximately 36% attributable to North America, approximately 5% to Asia and the balance to other regions. Strong demand growth during 1994 and the first half of 1995 allowed Kronos to maintain full capacity production rates in 1995. 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 and Kronos responded by reducing production rates. Kronos' average capacity utilization was approximately 95% in 1996. Demand improved in the second half of 1996 and throughout 1997. Kronos produced near full capacity in 1997. Pricing of TiO2 has historically been cyclical. Kronos anticipates its TiO2 operating income and margins will continue to improve in 1998 compared to 1997 as the impact of announced TiO2 price increases take effect. Demand for TiO2 in 1997 increased over 1996 and Kronos expects demand will increase in 1998, although Kronos' 1998 sales volume is expected to be slightly lower as a result of Kronos' lower inventory levels at the beginning of the year. Kronos believes continued growth in demand should result in significant improvement in average selling prices over the longer term. The Company has substantial operations and assets located outside the United States (principally Germany, Norway, Belgium and Canada). The U.S. dollar translated 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 revenues and expenses. A significant amount of the Company's sales are denominated in currencies other than the U.S. dollar (67% in 1997), 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 sales by $12 million and $58 million during 1996 and 1997, -24- respectively, compared to the year-earlier period. Fluctuation in the value of the U.S. dollar relative to other currencies similarly impacted the Company's operating expenses and the net impact of currency exchange rate fluctuations on operating income comparisons was not significant in 1996 or 1997. General corporate The following table sets forth certain information regarding general corporate income (expense).
Years ended December 31, Change ------------------------ ---------------- 1995 1996 1997 1996-95 1997-96 ---- ---- ---- ------- ------- (In millions) Securities earnings $ 7.4 $ 4.7 $ 5.4 $(2.7) $ .7 Corporate expenses, net (26.6) (17.2) (49.8) 9.4 (32.6) Interest expense (75.8) (69.3) (65.8) 6.5 3.5 ------ ------ ------- ----- ------ $(95.0) $(81.8) $(110.2) $13.2 $(28.4) ====== ====== ======= ===== ======
Securities earnings fluctuate in part based upon the amount of funds invested and yields thereon. Corporate expenses, net in 1997 exceeded that of 1996, primarily due to the $30 million noncash charge related to the Company's adoption of SOP 96-1, "Environmental Remediation Liabilities." See Note 2 to the Consolidated Financial Statements. This charge is included in selling, general and administrative expense in the Company's Consolidated Statements of Operations. Corporate expenses, net in 1996 were lower than 1995 due to lower provisions for environmental remediation cost. In 1998 the Company expects corporate expenses, net will be lower than 1997 due to the absence of the $30 million noncash charge. Interest expense Interest expense declined in 1997 from 1996 due to lower levels of Kronos' Deutsche mark-denominated debt, partially offset by higher variable interest rates on such debt. Interest expense in 1996 declined compared to 1995 principally due to lower interest rates on variable rate debt, principally Kronos' DM-denominated debt, partially offset by higher levels of such DM-denominated debt. Interest expense in 1998 is expected to be lower compared to 1997 due to lower expected levels of outstanding indebtedness, including required payments on the DM term loan and anticipated prepayments of the joint venture term loan. 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 1996 and 1997, 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 -25- 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 changed its estimate of the future tax benefit of certain U.S. tax credits which the Company believes satisfies the "more-likely-than-not" recognition criteria. Accordingly, the Company's valuation allowance was reduced by approximately $10 million. 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, 1997 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. Although average selling prices were 4% lower in 1997 compared to 1996, average selling prices in each of the last three quarters of 1997 were higher than the preceding quarter, reflecting the impact of industry-wide price increases announced beginning in late 1996. The upturn in prices follows a downward trend in prices that began in the last half of 1995. Operating cash flows were favorably impacted in 1997 versus 1996 due to higher production and sales volumes and $12.9 million of refunds of German trade capital taxes related to prior years. The Company expects prices will continue to increase in 1998; however, no assurance can be given that price trends will conform to the Company's expectations and future cash flows could be adversely affected should prices trend downward. Changes in the Company's inventories, receivables and payables (excluding the effect of currency translation) also contributed to the cash provided by operations in 1996 and 1997. Such changes used cash in 1995 primarily due to increased inventory levels. In 1995 net proceeds of $26 million from the sale of trading securities is included in cash provided from operations. Certain German income tax payments, discussed below, significantly decreased cash flows from operating activities in 1996. -26- The Company sold its specialty chemicals business to Elementis plc in January 1998 for cash proceeds of $465 million, including $20 million attributable to a five-year agreement by the Company not to compete in the rheological products business, and expects to recognize an after-tax gain of approximately $300 million in the first quarter of 1998. With the after-tax net proceeds of about $400 million, the Company prepaid and terminated its $117.5 million Rheox credit facility and terminated the related interest rate collar agreements. With the remaining proceeds, the Company intends to reduce outstanding indebtedness and invest in additional TiO2 production capacity. The Company has advised ICI of its interest in acquiring the portion of LPC it does not currently own. The indentures under which the Company's Senior Secured Notes and Senior Secured Discount Notes (collectively, the "Senior Notes") were issued provide that, if by November 1998 the Company has not applied the net cash proceeds from the sale of its specialty chemicals business in a manner permitted by the indentures, the Company must use the proceeds not so applied to offer to acquire the Senior Notes for cash on a pro rata basis at par value. Permitted uses of the proceeds include the acquisition of additional TiO2 capacity and the permanent reduction of certain debt other than the Senior Notes. The Senior Secured Discount Notes can first be redeemed at the option of the Company in October 1998 at a price of 106% of their principal amount, which the Company presently intends to do, depending on market conditions, availability of resources and other factors. The Company may acquire Senior Notes in the open market. The Company has notified the lender of its joint venture term loan that it intends to prepay the $42.4 million balance in March 1998. The Company's capital expenditures during the past three years include an aggregate of $58 million ($6 million in 1997) for the Company's ongoing environmental protection and compliance programs, including German and Norwegian off-gas desulfurization systems. The Company's estimated 1998 and 1999 capital expenditures are $30 million for each year and include $5 million for each year in the area of environmental protection and compliance primarily related to the off-gas desulfurization systems. In the last three years the Company spent $34 million ($7 million in 1997) in capital expenditures related to its substantially-completed debottlenecking project at its Leverkusen, Germany chloride-process TiO2 facility. The debottlenecking project increased the Company's annual attainable production by approximately 20,000 metric tons, and the Company estimates its worldwide annual attainable capacity is 420,000 metric tons. Capital expenditures of the manufacturing joint venture and the Company's discontinued operations are not included in the Company's capital expenditures. In 1997 the Company prepaid DM 207 million ($127 million when paid) of its DM term loan, repaid DM 43 million ($26 million when paid) of its DM revolving credit facility, repaid $15 million of its joint venture term loan and repaid DM 15 million ($9 million when paid) of its short-term DM-denominated notes payable. In the first quarter of 1997 Rheox refinanced its debt obtaining $125 million of new long-term financing and, with the proceeds, repaid a note payable -27- to NL. Rheox's financing activities are accumulated as "Rheox, net" in the Company's Consolidated Statements of Cash Flows. In 1996 the Company borrowed DM 144 million ($96 million when borrowed) under its DM credit facility. It 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 $15 million 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 $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. At December 31, 1997 the Company had cash and cash equivalents aggregating $106 million (45% held by non-U.S. subsidiaries) including restricted cash equivalents of $10 million. Excluding cash and cash equivalents of discontinued operations, the Company had $97 million in cash and cash equivalents (44% held by non-U.S. subsidiaries) including restricted cash equivalents of $10 million. At December 31, 1997 the Company's subsidiaries, excluding discontinued operations, had $84 million available for borrowing under non-U.S. credit facilities. At December 31, 1997 the Company had complied with all financial covenants governing its debt agreements. No dividends were paid in 1995 or 1997. Dividends paid during 1996 totaled $15.3 million. At December 31, 1997 the Company was 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 tax returns in various U.S. and non-U.S. jurisdictions are being examined and tax authorities have proposed or may propose tax deficiencies. The Company previously reached an agreement with the German tax authorities and paid certain tax deficiencies of approximately DM 44 million ($28 million when paid), including interest, which resolved significant tax contingencies for years through 1990. During 1997 the Company reached a tentative agreement with the German tax authorities regarding the years 1991 through 1994, and expects to pay DM 9 million ($5 million at December 31, 1997) during 1998 in settlement of certain tax issues. Certain other significant German tax contingencies remain outstanding for the years 1990 through 1996 and will continue to be litigated. With respect to these contingencies, the Company has received certain revised tax assessments aggregating DM 119 million ($66 million at December 31, 1997), including non-income tax related items and interest, for years through 1996. The Company expects to receive tax assessments for an additional DM 20 million ($11 million at December 31, 1997), including non-income tax related items and interest, for the years 1991 through 1994. No -28- payments of tax or interest deficiencies related to these assessments are expected until the litigation is resolved. During 1997 a German tax court proceeding involving a tax issue substantially the same as that involved in the Company's primary remaining tax contingency was decided in favor of the taxpayer. The German tax authorities have appealed that decision to the German Supreme Court; the Company believes that the decision by the German Supreme Court will be rendered within two years and will become a legal precedent which will likely determine the outcome of the Company's primary dispute with the German tax authorities, which assessments, including non-income tax related items and interest, aggregate DM 121 million. Although the Company believes that it will ultimately prevail, the Company has granted a DM 94 million ($53 million at December 31, 1997) lien on its Nordenham, Germany TiO2 plant in favor of the City of Leverkusen, and a DM 5 million ($3 million at December 31, 1997) lien in favor of the German federal tax authorities. During 1997 the Company received a tax assessment from the Norwegian tax authorities proposing tax deficiencies of NOK 51 million ($7 million at December 31, 1997) relating to 1994. The Company has appealed this assessment and expects to litigate this issue. No assurance can be given that these tax matters will be resolved in the Company's favor in view of the inherent uncertainties involved in court proceedings. The Company believes that it has adequately provided accruals for additional 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, 1997 the Company had net deferred tax liabilities of $132 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 $189 million at December 31, 1997, principally related to the U.S. and Germany, 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 business conducted through Kronos, the Company also has certain interests and associated liabilities relating to certain discontinued or divested businesses, and 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 -29- 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. As a result of certain computer programs being written using two digits rather than four to define the applicable year, certain of the Company's computer programs that have date-sensitive software may recognize a date using "00" as the year 1900 rather than the year 2000 (the "Year 2000 Issue"). This could result in a system failure or miscalculations causing disruptions of operations, including, among other things, a temporary inability to process transactions, send invoices or engage in normal business activities. The Company has completed the process of evaluating the modifications to critical software required to mitigate the Year 2000 Issue. The Company is in the process of communicating with its significant customers and suppliers to determine the extent to which the Company is vulnerable to those third parties' failure to minimize their own Year 2000 Issue. The Company is utilizing both internal and external resources to reprogram or replace and test its software and expects to complete substantially all of the requirements by the first quarter of 1999. However, if such modifications are not made or are not completed timely, the Year 2000 Issue could have a material adverse impact on the operations of the Company. In addition, there can be no assurance that the systems of other companies on which the Company's systems rely will be timely converted, or that a failure to convert by another company, or a conversion that is incompatible with the Company's systems, would not have a material adverse effect on the Company. The Company's estimate of the costs to complete the modifications to critical software required to address the Year 2000 Issue is not significant. -30- The date on which the Company plans to complete any necessary Year 2000 Issue modifications is based on management's best estimates, which were derived utilizing numerous assumptions of future events, including the continued availability of certain resources, third party modification plans and other factors. However, there can be no assurance that these estimates will be achieved and actual results could differ materially from those plans. Specific factors that might cause such material differences include, but are not limited to, the availability and cost of personnel trained in this area, the ability to locate and correct all relevant computer codes, and similar uncertainties. 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 in light of its capital resources 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 to manage its liquidity and capital resources. In the normal course of its business, the Company may review opportunities for 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.

These financial statements are the responsibility of the Company's management. Our responsibility is to express an opinion on these financial statements based on our audits. We conducted our audits in accordance with generally accepted auditing standards. Those standards require that we plan and perform the audit to obtain reasonable assurance about whether the financial statements are free of material misstatement.

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 titanium dioxide pigments ("TiO2") operations primarily through its wholly-owned subsidiary, Kronos, Inc. In January 1998 the specialty chemicals business of Rheox, Inc., a wholly-owned subsidiary of NL, was sold. See Note 20. At December 31, 1997 Valhi, Inc. and Tremont Corporation, each affiliates of Contran Corporation, held 57% and 18%, respectively, of NL's outstanding common stock, and together may be deemed to control the Company. At December 31, 1997 Contran and other entities related to Harold C. Simmons held approximately 93% of Valhi's and 49% of Tremont's outstanding common stock. Substantially all of Contran's outstanding voting stock is held by trusts established for the benefit of certain children and grandchildren of Mr. 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. Certain prior-year amounts have been reclassified to conform to the current year presentation, including reporting Rheox as a discontinued operation. 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 and bank deposits with original maturities of three months or less. Cash equivalents of approximately $6 million in 1996 and $5 million in 1997 is restricted under the Company's joint venture indebtedness agreement and, in addition, cash equivalents of approximately $5 million in 1996 and 1997 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. Realized and 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. Gains and losses on available-for-sale securities are recognized in income upon realization and 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, 1996 and 1997 no receivables for recoveries have been recognized. The Company adopted a new method of accounting as required by the AICPA's Statement of Position ("SOP") No. 96-1, "Environmental Remediation Liabilities," in the first quarter of 1997. The SOP, among other things, expands the types of costs which must be considered in determining environmental remediation accruals. As a result of adopting the SOP, the Company recognized a noncash cumulative charge of $30 million in the first quarter of 1997. The charge did not impact the Company's 1997 income tax expense because the Company believes the resulting deferred income tax asset does not currently satisfy the more-likely-than-not recognition criteria and, accordingly, the Company has established an offsetting valuation allowance. 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. Previously, such expenditures were expensed as incurred. Net sales Sales are recognized as products are shipped. F-12 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 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" recognition criteria. Interest rate swaps and contracts The Company periodically uses interest rate swaps and contracts (such as caps and floors) to manage interest rate risk with respect to financial assets or liabilities. The Company does not enter into these contracts for speculative purposes. Income or expense on swaps and contracts designated as hedges of assets or liabilities is recorded as an adjustment to interest income or expense. If the swap or contract is terminated, the resulting gain or loss is deferred and amortized over the remaining life of the underlying asset or liability. If the hedged instrument is disposed of, the swap or contract agreement is marked to market with any resulting gain or loss included with the gain or loss from the disposition. Any cost associated with the swap or contract is deferred and amortized over the life of the agreement. Earnings per common share The Company adopted Statement of Financial Accounting Standard ("SFAS") No. 128, "Earnings per Share", in the fourth quarter of 1997 and retroactively restated its reported earnings per common share. The new accounting standard requires both "basic" and "diluted" earnings per share presentation. Basic earnings per share is based on the weighted average number of common shares outstanding during each period. Diluted earnings per share is based on the weighted average common shares outstanding and the dilutive impact of outstanding stock options. The weighted average number of shares resulting from outstanding stock options which were excluded from the calculation of diluted earnings per share because their impact would have been antidilutive aggregated 1,878,000, 2,483,000 and 2,709,000 in 1995, 1996 and 1997, respectively. There were no adjustments to income (loss) from continuing operations or net income (loss) in the computation of earnings per common share. Both basic and diluted earnings per share from discontinued operations were $.37 per share, $.44 per share and $.40 per share in 1995, 1996 and 1997, respectively. New accounting principles not yet adopted The Company will adopt SFAS No. 130, "Reporting Comprehensive Income," in the first quarter of 1998. Upon adoption of SFAS No. 130, the Company will present a new Statement of Comprehensive Income which will report all changes in the Company's shareholders' deficit other than transactions with its shareholders. Comprehensive income pursuant to SFAS No. 130 would include the Company's consolidated net income (loss), as reported in the Consolidated F-13 Statement of Operations, plus the net change in the currency translation, pension liabilities and marketable securities components of shareholders' deficit. The Company will adopt SFAS No. 131, "Disclosures about Segments of an Enterprise and Related Information," no later than the fourth quarter of 1998. SFAS No. 131 will supersede the business segment disclosure requirements currently in effect under SFAS No. 14. SFAS No. 131, among other things, establishes standards regarding the information a company is required to disclose about its operating segments. SFAS No. 131 also provides guidance regarding what constitutes a reportable operating segment. The Company expects to have one operating segment pursuant to SFAS No. 131, the same one segment currently in effect under SFAS No. 14. Accordingly, segment disclosures pursuant to SFAS No. 131 are not expected to be materially different from the current disclosures pursuant to SFAS No. 14. The Company will adopt the disclosure requirements of SFAS No. 132, "Employers' Disclosures about Pensions and Other Postretirement Benefits," in the fourth quarter of 1998. SFAS No. 132 revises disclosure requirements for such pension and postretirement benefit plans to, among other things, standardize certain disclosures and eliminate certain other disclosures no longer deemed useful. SFAS No. 132 does not change the measurement or recognition criteria for such plans. Note 3 - Business and geographic segments: The Company's operations are conducted by Kronos in one operating business segment - TiO2. Titanium dioxide pigments are used to impart whiteness, brightness and opacity to a wide variety of products, including paints, plastics, paper, fibers and ceramics. General corporate assets consists principally of cash, cash equivalents and marketable securities. Discontinued operations consists of the Company's specialty chemicals business owned by Rheox which was sold in January 1998. See Note 20. At December 31, 1996 and 1997 the net assets of non-U.S. subsidiaries included in consolidated net assets approximated $124 million and $287 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. ("Tioxide"), a wholly-owned subsidiary of Imperial Chemicals Industries PLC F-16 ("ICI"). LPC owns and operates a chloride-process TiO2 plant in Lake Charles, Louisiana. ICI has agreed to sell Tioxide's non-North American operations to E.I. du Pont de Nemours & Co., subject to regulatory approval. ICI has announced it intends to sell Tioxide and the remaining North American operations in a separate transaction. The Company had advised ICI of its interest in acquiring the portion of LPC it does not currently own. 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. F-19 In the event of foreclosure, the Note holders would have access 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. The Company presently intends to redeem the Senior Secured Discount Notes in October 1998, depending on market conditions, availability of resources and other factors. 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, 1997 no amounts were available for payment of dividends pursuant to the terms of the indentures. Rheox sold its specialty chemicals business in January 1998. See Note 20. Under the terms of the indentures, the Company is required to make an offer to tender for a portion of the Notes, on a pro rata basis, (at par value for the Senior Secured Notes and at accreted value for the Senior Secured Discount Notes) to the extent that the amount of the net proceeds from the disposal of Rheox, as defined, are not used to either permanently pay down certain indebtedness of the Company or its subsidiaries or invest in additional productive assets by November 1998. The Senior Secured Discount Notes do not require semiannual cash interest payments until April 1999. The net carrying value of the Senior Secured Discount Notes per $100 principal amount at maturity was $79.87 and $90.59 at December 31, 1996 and 1997, respectively. At December 31, 1997 the quoted market price of the Senior Secured Notes was $111.17 per $100 principal amount and the quoted market price of the Senior Secured Discount Notes was $99.59 per $100 principal amount (1996 - $106.08 and $86.34, respectively). At December 31, 1997 the DM credit facility consisted of a DM 188 million term loan and a DM 230 million revolving credit facility, of which DM 100 million is outstanding. Borrowings bear interest at DM LIBOR plus 2.75% (1.625% margin at December 31, 1996) (4.76% and 6.28% at December 31, 1996 and 1997, respectively), and are collateralized by the stock of certain KII subsidiaries, pledges of certain Canadian and German assets and NL has guaranteed the facility. The term loan is due in semiannual installments commencing in September 1998 through September 1999 and the revolver is due in 2000. In accordance with the provisions of the DM credit agreement and as a result of higher than expected operating income in 1997 for KII, the Company intends to prepay in March 1998 F-20 DM 81 million ($45 million at December 31, 1997) of the term loan, of which DM 49 million ($27 million at December 31, 1997) will satisfy the September 1998 scheduled term loan payment and the remaining DM 32 million ($18 million at December 31, 1997) will reduce the March 1999 scheduled term loan payment. Unused lines of credit available for borrowing under the Company's non-U.S. credit facilities, including the DM facility, approximated $84 million at December 31, 1997. Borrowings under KLA's tranche of LPC's term loan bear interest at U.S. LIBOR plus 1.625% (7.245% and 7.438% at December 31, 1996 and 1997, respectively) and are repayable in quarterly installments through September 2000. The Company has notified the lender that it intends to prepay the loan in March 1998. Notes payable at December 31, 1996 and 1997 consists of DM 40 million and DM 25 million, respectively, of short-term borrowings due within one year from non-U.S. banks with interest rates ranging from 3.25% to 3.70% in 1996 and from 3.75% to 3.875% in 1997. The Company used a portion of the net proceeds from the January 1998 sale of substantially all of Rheox's net assets to prepay and terminate the Rheox bank credit facility. See Note 20. At December 31, 1997 this facility consisted of a $117.5 million term loan due in quarterly installments through January 2004 and a $25 million revolver (nil outstanding) due no later than January 2004. Borrowings bore interest at LIBOR plus a margin of .75% to 1.75%, depending upon the level of a certain Rheox financial ratio (the margin was 1.5% at December 31, 1997 resulting in a rate of 7.3%), and were collateralized principally by the stock of Rheox and its U.S. subsidiaries. The interest rate on outstanding prime-rate borrowings under a prior Rheox bank credit facility at December 31, 1996 was 9.8%. The aggregate maturities of long-term debt at December 31, 1997 on a historical and a pro forma basis, giving effect for the January 1998 sale of Rheox described above and in Note 20, are shown in the table below.

F-21 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 in 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 executives, and contributions are based on a formula involving eligible earnings. The Company's expense related to these plans included in continuing operations was $.7 million in 1995, $.8 million in 1996 and $.7 million in 1997. Expense related to these plans included in discontinued operations was $.5 million in each of 1995, 1996 and 1997. 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 the funding requirements of the Employee Retirement Income Security Act of 1974, as amended. 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, ----------------------------------------- 1995 1996 1997 ---------- --------- ---------- (Percentages) Discount rate 7.0 to 8.5 6.5 to 8.5 6.0 to 8.5 Rate of increase in future compensation levels 3.5 to 6.0 3.5 to 6.0 3.0 to 6.0 Long-term rate of return on plan assets 8.0 to 9.0 7.0 to 9.0 6.0 to 9.0
During 1996 the Company curtailed certain U.S. employee pension benefits and recognized a gain of $4.6 million, of which $2.7 million is included in discontinued operations. 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. 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 F-22 assets, will result in additional increases or decreases in accrued pension liabilities, pension expense and funding requirements in future periods. At December 31, 1997 77% 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-23 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 in relation to the annual operating plan 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, 1997, the expected rate of increase in health care costs is 7% in 1998, 6% in 1999 and 5% in 2000 and years thereafter. Other assumptions used to measure the liability and expense are presented below.
Years ended December 31, ------------------------ 1995 1996 1997 ---- ---- ---- (Percentages) Discount rate ....................................... 7.5 7.5 7.0 Long-term rate for compensation increases ........... 4.5 6.0 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 $.1 million in 1997, and the actuarial present value of accumulated benefit obligations at December 31, 1997 would have increased by approximately $1.2 million. During 1996 the Company curtailed certain Canadian employee OPEB benefits and recognized a $1.3 million gain. 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, 1997, 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, 1997, an aggregate of 1.9 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, 1997 there were options to acquire 9,000 shares of common stock outstanding of which 7,000 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-26

At December 31, 1995, 1996 and 1997 options to purchase 1,189,907, 1,660,068 and 1,801,955 shares, respectively, were exercisable and options to purchase 301,002 shares become exercisable in 1998. Of the exercisable options at December 31, 1997, options to purchase 1,380,296 shares had exercise prices less than the Company's December 31, 1997 quoted market price of $13.625 per share. Outstanding options at December 31, 1997 expire at various dates through 2007, with a weighted-average remaining life of five 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, 1996 and 1997. The weighted average fair values of options granted during 1995, 1996 and 1997 were $6.02, $8.38 and $6.35 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, 1996 and 1997: stock price volatility of 31%, 42% and 37% in 1995, 1996 and 1997, respectively; risk-free rate of return of 5%; no dividend yield; and an expected term of 9 years. For purposes of pro forma disclosures, the estimated fair value of the options is amortized to expense over the options' vesting period. F-27 The Company's pro forma net income (loss) and basic net income (loss) per common share were as follows. The pro forma impact on earnings per common share for 1995, 1996 and 1997 is not necessarily indicative of future effects on earnings per share.

Certain of the Company's tax returns in various U.S. and non-U.S. jurisdictions are being examined and tax authorities have proposed or may propose tax deficiencies. The Company previously reached an agreement with the German tax authorities and paid certain tax deficiencies of approximately DM 44 million ($28 million when paid), including interest, which resolved significant tax contingencies for years through 1990. During 1997 the Company received DM 19 million ($11 million when received) in trade capital tax refunds based on (i) recent court decisions which resulted in reducing the trade capital tax base and (ii) prior agreements between the Company and the German tax authorities regarding payment of disputed taxes. The Company also reached a tentative agreement with the German tax authorities regarding the years 1991 through 1994, and expects to pay DM 9 million ($5 million at December 31, 1997) during 1998 in settlement of certain tax issues. Certain other significant German tax contingencies remain outstanding for the years 1990 through 1996 and will continue to be litigated. With respect to these contingencies, the Company has received certain revised tax assessments aggregating DM 119 million ($66 million at December 31, 1997), including non-income tax related items and interest, for years through 1996. The Company expects to receive tax assessments for an additional DM 20 million ($11 million at December 31, 1997), including non-income tax related items and interest, for the years 1991 through 1994. No payments of F-31 tax or interest deficiencies related to these assessments are expected until the litigation is resolved. During 1997 a German tax court proceeding involving a tax issue substantially the same as that involved in the Company's primary remaining tax contingency was decided in favor of the taxpayer. The German tax authorities have appealed that decision to the German Supreme Court; the Company believes that the decision by the German Supreme Court will be rendered within two years and will become a legal precedent which will likely determine the outcome of the Company's primary dispute with the German tax authorities, which assessments, including non-income tax related items and interest, aggregate DM 121 million. Although the Company believes that it will ultimately prevail, the Company has granted a DM 94 million ($53 million at December 31, 1997) lien on its Nordenham, Germany TiO2 plant in favor of the City of Leverkusen, and a DM 5 million ($3 million at December 31, 1997) lien in favor of the German federal tax authorities. During 1997 the Company received a tax assessment from the Norwegian tax authorities proposing tax deficiencies of NOK 51 million ($7 million at December 31, 1997) relating to 1994. The Company has appealed this assessment and expects to litigate this issue. No assurance can be given that these tax matters will be resolved in the Company's favor in view of the inherent uncertainties involved in court proceedings. The Company believes that it has adequately provided accruals for additional 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. The Company utilized foreign tax credit carryforwards of $11 million in 1995, $2 million in 1996 and $5 million in 1997, and utilized U.S. net operating loss carryforwards of $8 million in 1995 and $26 million in 1997, to reduce U.S. federal income tax expense. At December 31, 1997 for U.S. federal income tax purposes, the Company had approximately $19 million of unutilized foreign tax credit carryforwards expiring during 1998 through 2001 and approximately $12 million of alternative minimum tax credit carryforwards with no expiration date. The Company also had approximately $350 million of income tax loss carryforwards in Germany with no expiration date. F-32 Note 14 - Other income, net:

Technology fee income was amortized by the straight-line method over a three-year period ending October 1996. Note 15 - Other items: Advertising costs included in continuing operations, expensed as incurred, were $1 million in each of 1995, 1996 and 1997. Research, development and certain sales technical support costs included in continuing operations, expensed as incurred, approximated $9 million in 1995, $8 million in 1996 and $7 million in 1997. Interest capitalized related to continuing operations in connection with long-term capital projects was $1 million in 1995 and $2 million in each of 1996 and 1997. 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 F-33 as set forth in this Annual Report on Form 10-K, the Company from time to time 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 1995 and 1996 and $.5 million in 1997. 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 (income) related to the Valhi ISA was $.1 million in each of 1995 and 1996 and $(.1) million in 1997. 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 $.1 million in each of 1995 and 1996 and $.2 million in 1997. The Company is party to an intercorporate services agreement (the "Timet ISA") with Titanium Metals Corporation ("Timet"), approximately 30% of the outstanding common stock of which is held by Tremont. Under the terms of the contract, the Company provides certain management and financial services to Timet on a fee basis. Management services fee income related to the Timet ISA was $.3 million in 1997. Purchases from LPC were $69.7 million in 1995, $69.8 million in 1996 and $78.1 million in 1997. Certain employees of the Company have been granted options to purchase Valhi common stock under the terms of Valhi's stock option plans. The Company and Valhi have agreed that the Company will pay Valhi the aggregate difference between the option price and the market value of Valhi's common stock on the exercise date of such options. For financial reporting purposes, the Company accounts for the related expense (income) ($(25,000) in 1995, $1,000 in 1996 and $68,000 in 1997) in a manner similar to accounting for SARs. At December 31, 1997 an employee of the Company held vested options to purchase 15,000 shares of Valhi common stock at an exercise price of $14.66 per share which exceeded Valhi's December 31, 1997 quoted market price per share of $9.4375. F-34 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-35 Net rent expense included in continuing operations aggregated $7 million in 1995, $8 million in 1996 and $7 million in 1997. At December 31, 1997 minimum rental commitments under the terms of noncancellable operating leases, excluding discontinued operations, were as follows:

Capital expenditures At December 31, 1997 the estimated cost to complete capital projects in process approximated $4 million, including $2 million to complete a debottlenecking expansion project at the Company's Leverkusen, Germany chloride-process TiO2 facility. 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 $101 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. F-36 The Company believes that these actions are without merit, intends to continue to deny all allegations of wrongdoing and liability and to defend all 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, damages for personal injury or property damage and/or damages for injury to natural resources. 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, 1997 the Company had accrued $135 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 $175 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 adopted the AICPA's Statement of Position 96-1, "Environmental Remediation Liabilities," in the first quarter of 1997, increasing its environmental liability by $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 F-37 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 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 more than 90% of net sales from continuing operations during each of 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 1995, 37% in 1996 and 36% in 1997 of sales were attributable to North America. Consolidated cash, cash equivalents and restricted cash includes $63 million and $53 million invested in U.S. Treasury securities purchased under short-term agreements to resell at December 31, 1996 and 1997, respectively, of which $53 million and $45 million, respectively, of such securities are held in trust for the Company by a single U.S. bank.

Fair value of the Company's marketable securities and Notes are based upon quoted market prices and the fair value of the Company's common shareholder's equity (deficit) is based upon quoted market prices for NL's common stock. In connection with its credit facility, Rheox entered into interest rate collar agreements in 1997 which effectively set minimum and maximum U.S. LIBOR interest rates of 5.25% and 8%, respectively, on $50 million principal amount of its variable-rate bank term loan through May 2001. The margin on such borrowings ranged from .75% to 1.75%, depending upon the level of a certain Rheox financial ratio. The Company was exposed to interest rate risk in the event of nonperformance by the other parties to the agreements. At December 31, 1997 the estimated fair value of such agreements was estimated to be a $.1 million payable. Such fair value represented the amount the Company would pay if it terminated the collar agreements at that date, and is based upon quotes obtained from the counter party financial institutions. The Company terminated these agreements in the first quarter of 1998 concurrently with the prepayment and termination of the underlying credit facility. See Note 20. The Company held no derivative financial instruments at December 31, 1996. F-39 Note 19 - Quarterly financial data (unaudited):

F-40 Note 20 - Subsequent event: The specialty chemical business of Rheox was sold to Elementis plc for $465 million in January 1998, including $20 million attributable to a five-year agreement by the Company not to compete in the rheological products business. A portion of the net proceeds were used to prepay and terminate Rheox's bank credit facility. The Company expects to recognize an after-tax gain of approximately $300 million on the disposal of this business segment in the first quarter of 1998. Had the sale occurred at December 31, 1997, the Company's pro forma unaudited cash and cash equivalents would have been $326 million; notes payable and long-term debt, including the current portion, would have been $641 million; and shareholders' equity would have been $40 million. As a result of the sale, the Company has presented the results of this business segment as discontinued operations for all periods presented. Following the sale, Rheox, Inc. was renamed NL Capital Corporation. Condensed income statements related to discontinued operations for 1995, 1996 and 1997 are as follows. Interest expense has been allocated to discontinued operations based on the amount of debt specifically attributed to Rheox's operations.

                       AGREEMENT TO DEFER BONUS PAYMENT

      This AGREEMENT TO DEFER BONUS PAYMENT (this "Agreement") is made effective
as of the 20th day of February  1998 between NL  Industries,  Inc., a New Jersey
corporation (the "Corporation") and Dr. Lawrence A. Wigdor ("Executive").

      WHEREAS,  Executive  was  awarded a Special  Bonus in  recognition  of his
performance which substantially contributed to the success of the Corporation;

      WHEREAS, The Corporation and Executive desire to defer payment of $850,000
(the  "Deferred  Special  Bonus")  which  Executive,  in  the  absence  of  this
Agreement,  would be entitled to receive  immediately  with  respect to services
performed by Executive for the Corporation; and

      WHEREAS,  the Corporation and Robert D. Hardy as trustee,  will enter into
an agreement (the "Trust Agreement") which establishes an irrevocable trust (the
"Trust")  which is  intended  to hold and invest an amount of funds equal to the
Deferred  Special  Bonus until such bonus is paid to Executive  pursuant to this
Agreement;

      NOW,  THEREFORE,  in  consideration of the agreements set forth herein and
for other good and valuable consideration,  the receipt and sufficiency of which
is hereby acknowledged, the parties hereto agree as follows:

            1. The Deferred  Special  Bonus shall be paid to  Executive,  or his
designated  beneficiaries,  upon the earliest to occur of (a) the termination of
Executive's employment (including  Executive's  resignation) for any reason, (b)
Executive's  death,  or (c) such date as shall be determined  by the  Management
Development  and   Compensation   Committee  of  the  Board  of  Directors  (the
"Committee")  in its sole  discretion  but in no event later than ten (10) years
after the effective date of this Agreement.

            2. The Deferred  Special  Bonus shall accrue  interest  beginning on
February 20, 1998 up to and  including the date such amount is paid to Executive
pursuant  to  Paragraph 1 hereof (the  "Deferred  Payment  Date") and the entire
amount of such accrued  interest  shall be paid to Executive,  or his designated
beneficiaries,  on the Deferred  Payment Date. Such interest shall accrue at the
rate of eight and one-half percent (8.50%) per annum.  Interest accrued pursuant
to this Paragraph 2 shall compound on a semi-annual  basis and shall be computed
for the actual  number of days elapsed on the basis of a year  consisting of 365
or 366 days.

            3. The Corporation  shall immediately enter into the Trust Agreement
and thereby  establish the Trust.  The  Corporation  shall  contribute an amount
equal to the Deferred Special Bonus to the Trust.

            4. Subject to the terms of the Trust Agreement,  the Corporation may
satisfy  its  payment   obligations   to   Executive,   or  to  his   designated
beneficiaries, under this Agreement by (a)






directing  the Trustee to make such payments from the principal and /or earnings
of the Trust, (b) making such payments directly from the Corporation's  internal
funds, or (c) by any  combination of (a) and (b),  provided that all payments to
Executive, or to his designated beneficiaries,  pursuant to this Agreement shall
be made in immediately available funds.

            5. The Corporation shall withhold,  either from the Deferred Special
Bonus in the year such  amount is paid to  Executive  pursuant  to  Paragraph  1
hereof,  or from  any  salary,  bonus  or  other  compensatory  payment  made to
Executive as the Corporation in its sole discretion may determine,  such amounts
as is  required  by law to be  withheld  in 1996 or  after,  as the case may be,
pursuant to Code SS 3101 and 3121(v)(2) or successor provisions thereof.

            6. Title to and beneficial ownership of any assets,  whether cash or
investments  and  whether  held  by the  Corporation  or the  Trust,  which  the
Corporation may earmark to meet its payment  obligations to Executive under this
Agreement,  shall at all  times  remain  in the  Corporation  or the  Trust,  as
applicable,  and Executive and his designated  beneficiaries  shall not have any
property  interest  whatsoever in any specific  assets of the Corporation or the
Trust.  Any right of the  Executive or any of his  designated  beneficiaries  to
receive  payments from the Corporation  under this Agreement shall be no greater
than the right of any unsecured general creditor of the Corporation.

            7. The right of Executive  or any other person to any payment  under
this Agreement shall not be assigned, transferred,  pledged or encumbered except
by will or by the laws of descent and distribution.

            8. If the  Committee  shall find that any person to whom any payment
is payable under this Agreement is unable to care for his or her affairs because
of illness or  accident,  or is a minor,  any  payment due (unless a prior claim
therefor  shall  have  been made by a duly  appointed  guardian  or other  legal
representative)  may be paid to the  spouse,  a child,  a parent,  a brother  or
sister, or the person or persons designated by the Executive in writing,  or, in
the absence of any of the  foregoing,  to any one or more persons  deemed by the
Committee to be appropriate.  Any such payment shall be a complete  discharge of
the liabilities of the Corporation under this Agreement.

            9. Nothing  contained  herein shall be construed as conferring  upon
Executive the right to continue in the employ of the Corporation as an executive
or in any other capacity.

            10 This Agreement  shall be binding upon and inure to the benefit of
the  Corporation,  it successors  and assigns,  and the Executive and his heirs,
executors, administrators and legal representatives.

            11. This Agreement  contains the entire agreement of and between the
parties with respect to the subject  matter  hereof,  and  supersedes  any prior
understandings,  agreements,  or  representations  by or  between  the  parties,
written or oral, which may have related to the subject matter hereof in any way.
In the event of any conflict between the terms and provisions of this

                                      2





Agreement and the terms and provisions of any employment or severance  agreement
entered into by the parties  hereto,  the terms and provisions of this Agreement
shall govern.

            12.  The  Agreement  shall be  governed  by the laws of the State of
Texas without giving effect to any choice of law or conflict of law provision or
rule (whether of the State of Texas or any other  jurisdiction) that would cause
the application of the laws of any jurisdiction other than the State of Texas.

as of the date first written above.

                                TRUST AGREEMENT


            This  Agreement  is made  effective  as of the 20th day of February,
1998 by and between NL Industries,  Inc. (the "Corporation") and Robert D. Hardy
(the "Trustee");

            WHEREAS,  the Corporation  and Lawrence A. Wigdor (the  "Executive")
have  entered  into  the  Agreement  to  Defer  Bonus  Payment  (the   "Deferral
Agreement") attached hereto as Exhibit A;

            WHEREAS,  the Corporation has incurred or expects to incur liability
under the terms of such Deferral Agreement with respect to the Executive;

            WHEREAS,  the Corporation  wishes to establish a trust  (hereinafter
called the  "Trust")  and to  contribute  to the Trust assets that shall be held
therein,  subject to the claims of the  Corporation's  creditors in the event of
the Corporation's Insolvency, as herein defined, until paid to the Executive and
his  beneficiaries in such manner and at such times as specified in the Deferral
Agreement;

            WHEREAS,  it is the  intention  of the parties that this Trust shall
constitute  an  unfunded  arrangement  and shall not  affect  the  status of the
Deferral  Agreement as an unfunded plan  maintained for the purpose of providing
deferred  compensation  for a member of the select group of management or highly
compensated  employees for purposes of Title I of the Employee Retirement Income
Security Act of 1974;

            WHEREAS,   it  is  the   intention  of  the   Corporation   to  make
contributions to the Trust to provide itself with a source of funds to assist it
in the meeting of its liabilities under the Deferral Agreement;

            NOW, THEREFORE,  the parties do hereby establish the Trust and agree
that the Trust shall be comprised, held and disposed of as follows:

            Section 1.  Establishment of Trust

            (a) The  Corporation  hereby deposits with the Trustee in trust $100
or such other amount as  determined by the  Corporation,  which shall become the
principal of the Trust to be held,  administered  and disposed of by the Trustee
as provided in this Trust Agreement.

            (b) The Trust hereby established shall be irrevocable.

            (c) The  Trust is  intended  to be a  grantor  trust,  of which  the
Corporation is the grantor,  within the meaning of subpart E, part I, subchapter
J, chapter 1, subtitle A of the Internal  Revenue Code of 1986, as amended,  and
shall be construed accordingly.


                                      1





            (d) The  principal of the Trust,  and any earnings  thereon shall be
held  separate and apart from other funds of the  Corporation  and shall be used
exclusively for the uses and purposes of the Executive and general  creditors as
herein set forth.  The Executive and his  beneficiaries  shall have no preferred
claim on, or any beneficial  ownership interest in, any assets of the Trust. Any
rights created under the Deferral  Agreement and this Trust  Agreement  shall be
mere unsecured contractual rights of the Executive and his beneficiaries against
the  Corporation.  Any assets held by the Trust will be subject to the claims of
the Corporation's  general creditors under federal and state law in the event of
Insolvency, as defined in Section 3(a) herein.

            (e) The Corporation shall make additional  deposits of cash or other
property in trust with the Trustee in accordance  with the terms of the Deferral
Agreement to augment the principal to be held,  administered  and disposed of by
the  Trustee as provided  in this Trust  Agreement.  Neither the Trustee nor the
Executive or any of his beneficiaries  shall have any right to compel additional
deposits, except as may be required by the terms of the Deferral Agreement.

            Section 2.  Payments to Executive and His Beneficiaries.

            (a) The Corporation  shall deliver to the Trustee a written schedule
(the "Payment  Schedule")  that indicates the amounts  payable in respect of the
Executive  (and his  beneficiaries),  that provides the amounts so payable,  the
form in which  such  amount is to be paid,  and the dates  for  payment  of such
amounts. Except as otherwise provided herein, the Trustee shall make payments to
the Executive and his  beneficiaries  in accordance with such Payment  Schedule.
The Corporation  may amend or modify such Payment  Schedule from time to time by
providing the Trustee with written  notice of such  amendments.  The Trustee may
conclusively rely on such Payment Schedule. The Trustee shall make provision for
the reporting and  withholding of any federal,  state or local taxes that may be
required to be withheld with respect to the payment of benefits  pursuant to the
terms  of  the  Deferral  Agreement  and  shall  pay  amounts  withheld  to  the
appropriate  taxing  authorities  or  determine  that  such  amounts  have  been
reported, withheld and paid by the Corporation.

            (b)  The  entitlement  of  the  Executive  or his  beneficiaries  to
benefits under the Deferral  Agreement shall be determined by the Corporation in
accordance  with the  terms of the  Deferral  Agreement,  and any claim for such
benefits  shall be  considered  and  reviewed  under the  terms of the  Deferral
Agreement.

            (c) The  Corporation  may make  payment of benefits  directly to the
Executive  or his  beneficiaries  as they  become  due  under  the  terms of the
Deferral Agreement.  The Corporation shall notify the Trustee of its decision to
make payment of benefits  directly  prior to the time amounts are payable to the
Executive or his beneficiaries. Such payments by the Corporation shall not amend
the Payment Schedule unless the Corporation specifically amends said Schedule in
writing.  In addition,  if the principal of the Trust, and any earnings thereon,
are not  sufficient to make payments of benefits in accordance  with the Payment
Schedule,  the  Corporation  shall make the  balance of each such  payment as it
falls due. The Trustee shall notify the Corporation where principal and earnings
are not sufficient.

                                      2





            Section  3.  Trustee  Responsibility  Regarding  Payments  to  Trust
            Beneficiary When the Corporation Is Insolvent.

            (a) The Trustee  shall not make any payments to the Executive or his
beneficiaries  if  the  Corporation  is  Insolvent.  Notwithstanding  any  other
provision of this Trust Agreement,  all determinations by the Trustee under this
Trust Agreement regarding whether the Corporation is solvent or Insolvent should
be  based  solely  on  the  written  representation  to  the  Trustee  from  the
Corporation's   Controller  or  Chief  Financial  Officer  without   independent
investigation by the Trustee.  The Corporation  shall be considered  "Insolvent"
for purposes of this Trust Agreement if (i) the Corporation is unable to pay its
debts as they  become  due,  or (ii) the  Corporation  is  subject  to a pending
proceeding as a debtor under the United States Bankruptcy Code.

            (b) At all times during the  continuance of this Trust,  as provided
in Section 1(d) hereof,  the  principal and income of the Trust shall be subject
to claims of general creditors of the Corporation under federal and state law as
set forth below.

                  (1) The Board of Directors,  the Chief Executive Officer,  the
Chief Financial Officer ("CFO") and the Controller of the Corporation shall have
the duty to inform the Trustee in writing of the  Corporation's  Insolvency with
respect to any payment date on the Payment Schedule.  If a person claiming to be
a  creditor  of the  Corporation  alleges in  writing  to the  Trustee  that the
Corporation  has become  Insolvent,  the  Trustee  shall  determine  whether the
Corporation  is  Insolvent;  such  determination  shall be made based  solely on
written  representation  from the  Corporation's  Controller or Chief  Financial
Officer. Pending such determination,  the Trustee shall not make any payments to
Executive or his beneficiaries.

                  (2)  Unless  the   Trustee  has   received   notice  from  the
Corporation that the Corporation is Insolvent, the Trustee shall have no duty at
any time to inquire whether the  Corporation is Insolvent.  The Trustee shall in
all  events  rely on such  representation  from  the  Corporation  in  making  a
determination concerning the Corporation's solvency.

                  (3) In the event that the  Corporation's  Controller  or Chief
Financial  Officer  has  notified  the  Trustee in writing of the  Corporation's
Insolvency,  the Trustee  shall not make any  payments to the  Executive  or his
beneficiaries  and shall  hold the  assets of the Trust for the  benefit  of the
Corporation's  general  creditors.  Nothing in this Trust Agreement shall in any
way  diminish  or impair any rights of the  Executive  or his  beneficiaries  to
pursue their  rights as general  creditors  of the  Corporation  with respect to
payments due under the Deferral Agreement or otherwise.

                  (4) The Trustee shall resume making  payments to the Executive
or his  beneficiaries  in accordance with Section 2 of this Trust Agreement only
after the Trustee has determined that the Corporation is not Insolvent (or is no
longer Insolvent).

            (c)  Provided  that  there are  sufficient  assets,  if the  Trustee
discontinues  making payments from the Trust pursuant to Section 3(b) hereof and
subsequently resumes such payments,

                                      3





the first  payment  following  such  discontinuance  shall include the aggregate
amount of all payments due to the Executive or his beneficiaries under the terms
of the  Deferral  Agreement  for the  period  of such  discontinuance,  less the
aggregate  amount of any payments made to the Executive or his  beneficiaries by
the Corporation in lieu of the payments  provided for hereunder  during any such
period of discontinuance.

            Section 4.  Payments to the Corporation.

            Except as provided in Section 3 hereof,  the Corporation  shall have
no right or power to direct  the  Trustee  to return  to the  Corporation  or to
divert to others any of the Trust assets  before all payments  have been made to
the  Executive  or his  beneficiaries  pursuant  to the  terms  of the  Deferral
Agreement.

            Section 5.  Investment Authority.

            In no event may the Trustee invest in securities (including stock or
rights to acquire stock) or obligations issued by the Corporation,  other than a
de  minimis  amount  held in common  investment  vehicles  in which the  Trustee
invests.  All rights  associated  with assets of the Trust  shall be  exercised,
solely in accordance with the directions of the  Corporation,  by the Trustee or
the person designated by the Trustee, and shall in no event be exercisable by or
rest with the Executive.

            Section 6.  Disposition of Income.

            During the term of this Trust, all income received by the Trust, net
of expenses and taxes, shall be accumulated and reinvested.

            Section 7.  Accounting by the Trustee.

            The  Trustee  shall  keep  records  of such  investments,  receipts,
disbursements,  and all  other  transactions  required  to be made,  as shall be
agreed upon in writing between the  Corporation and the Trustee.  Within 60 days
following  the close of each  calendar year and within 60 days after the removal
or  resignation of the Trustee,  the Trustee shall deliver to the  Corporation a
written  account of its  administration  of the Trust during such year or during
the period from the close of the last preceding year to the date of such removal
or resignation, setting forth all investments, receipts, disbursements and other
transactions  effected by it,  including a  description  of all  securities  and
investments  purchased and sold with the cost or net proceeds of such  purchases
or sales  (accrued  interest paid or  receivable  being shown  separately),  and
showing all cash,  securities and other property held in the Trust at the end of
such year or as of the date of such removal or resignation,  as the case may be.
In the event  the  Trustee  delegates  the  obligations  of this  section  to an
employee of the Corporation, such obligations shall be deemed to be fulfilled by
the Trustee.


                                      4





            Section 8.  Responsibility of the Trustee.

            (a) The  Trustee  shall  act  with the  care,  skill,  prudence  and
diligence under the  circumstances  then prevailing that a prudent person acting
in like  capacity and familiar  with such matters would use in the conduct of an
enterprise of a like character and with like aims, provided,  however,  that the
Trustee shall incur no liability to any person for any action taken  pursuant to
a  direction,  request  or  approval  given by the  Corporation  in  connection,
directly or indirectly, with, the terms of the Deferral Agreement or this Trust.
In the event of a dispute between the  Corporation and a party,  the Trustee may
apply to a court of competent jurisdiction to resolve the dispute.

            (b) The  Corporation  agrees  to  indemnify  and  hold  the  Trustee
harmless from any and all costs,  fees,  expenses  (including without limitation
attorney's  fees and  expenses),  claims or  lawsuits  by any  person or entity,
liabilities or obligations of any type or nature arising or related, directly or
indirectly,  to the Deferral  Agreement,  this Trust or any action or failure to
act by  the  Trustee  in  connection  in  any  way  with  any of the  foregoing.
Furthermore,  if the Trustee  undertakes  or defends any  litigation  arising in
connection  with this Trust,  the  Corporation  agrees to indemnify  the Trustee
against the  Trustee's  costs,  expenses  and  liabilities  (including,  without
limitation,  attorneys'  fees and  expenses)  relating  thereto and to be solely
liable for such payments.  If the Corporation does not pay such costs,  expenses
and  liabilities in a reasonably  timely manner,  the Trustee may obtain payment
from the Trust.

            (c) The  Trustee  may consult  with legal  counsel  (who may also be
counsel  for the  Corporation  generally)  with  respect to any of its duties or
obligations hereunder.

            (d) The Trustee may hire and the  Corporation  may make available to
the Trustee  agents,  accountants,  actuaries,  investment  advisors,  financial
consultants or other  professionals to assist it in performing any of its duties
or  obligations  hereunder.  In  addition,  the Trustee may  delegate any of its
duties under this Trust to employees and management of the  Corporation  and the
Trustee may  conclusively  rely on the reports of such  employees and management
without further investigation.

            (e) The Trustee shall have, without exclusion,  all powers conferred
on the Trustees by applicable law, unless expressly  provided  otherwise herein,
provided, however, that if an insurance policy is held as an asset of the Trust,
the Trustee shall have no power to name a  beneficiary  of the policy other than
the Trust,  to assign the policy (as distinct from conversion of the policy to a
different form) other than to a successor Trustee,  or to loan to any person the
proceeds of any borrowing against such policy.

            (f)  Notwithstanding  any powers granted to the Trustee  pursuant to
this Trust  Agreement or to applicable law, the Trustee shall not have any power
that could give this Trust the  objective of carrying on a business and dividing
the gains therefrom,  within the meaning of section  301.7701-2 of the Procedure
and  Administrative  Regulations  promulgated  pursuant to the Internal  Revenue
Code.

                                      5





            Section 9.  Compensation and Expenses of Trustee.

            The Corporation shall pay all  administrative and Trustee's fees and
expenses. If not so paid, the fees and expenses shall be paid from the Trust.

            Section 10.  Resignation and Removal of Trustee.

            (a) The  Trustee  may  resign at any time by  written  notice to the
Corporation,  which  shall be  effective  15 days after  receipt of such  notice
unless the Corporation and the Trustee agree otherwise.

            (b) The Trustee may be removed by the  Corporation on 15 days notice
to the Trustee or upon shorter notice accepted by the Trustee.

            (c) Upon a Change of Control, as defined herein, the Trustee may not
be removed by the Corporation for 18 months.

            (d) Upon  resignation or removal of the Trustee and appointment of a
successor Trustee, all assets shall subsequently be transferred to the successor
Trustee.  The transfer shall be completed within 30 days after receipt of notice
of resignation,  removal or transfer,  unless the  Corporation  extends the time
limit.

            (e) If the  Trustee  resigns or is  removed,  a  successor  shall be
appointed,  in  accordance  with  Section 11 hereof,  by the  effective  date of
resignation or removal under  paragraphs (a) or (b) of this section.  If no such
appointment  has been  made,  the  Trustee  may  apply  to a court of  competent
jurisdiction for appointment of a successor or for instructions. All expenses of
the Trustee in connection with the proceeding shall be allowed as administrative
expenses of the Trust.

            Section 11.  Appointment of Successor.

            (a) If the Trustee  resigns or is removed in accordance with Section
10(a) or (b) hereof, the Corporation may appoint any third party, such as a bank
trust  department or other party that may be granted  corporate  trustee  powers
under state law, as a successor  to replace  the  Trustee  upon  resignation  or
removal.  The appointment shall be effective when accepted in writing by the new
Trustee,  who shall have all of the  rights  and  powers of the former  Trustee,
including ownership rights in the Trust assets. The former Trustee shall execute
any  instrument  necessary or  reasonably  requested by the  Corporation  or the
successor Trustee to evidence the transfer.

            (b) The  successor  Trustee need not examine the records and acts of
any prior Trustee and may retain or dispose of existing Trust assets, subject to
Sections 7 and 8 hereof.  The successor Trustee shall not be responsible for and
the Corporation  shall indemnify and defend the successor Trustee from any claim
or liability  resulting from any action or inaction of any prior Trustee or from
any other past event, or any condition existing at the time it becomes successor
Trustee.

                                      6





            Section 12.  Amendment or Termination.

            (a) This Trust  Agreement  may be  amended  by a written  instrument
executed by the Trustee and the Corporation.  Notwithstanding the foregoing,  no
such amendment shall conflict with the terms of the Deferral  Agreement or shall
make the Trust revocable.

            (b) The  Trust  shall  not  terminate  until  the date on which  the
Executive and his  beneficiaries are no longer entitled to any payments pursuant
to the terms of the Deferral Agreement. Upon termination of the Trust any assets
remaining in the Trust shall be returned to the Corporation.

            Section 13.  Miscellaneous.

            (a) Any provision of this Trust Agreement prohibited by law shall be
ineffective  to the extent of any such  prohibition,  without  invalidating  the
remaining provisions hereof.

            (b) No amount  payable to the Executive or any of his  beneficiaries
under this Trust  Agreement may be  anticipated,  assigned  (either at law or in
equity), alienated, pledged, encumbered or subjected to attachment, garnishment,
levy, execution or other legal or equitable process.

            (c) This Trust  Agreement  shall be  governed  by and  construed  in
accordance with the laws of Texas.

            (d) For  purposes  of this Trust,  Change of Control  shall mean the
purchase or other acquisition by any person, entity or group of persons,  within
the meaning of section  13(d) or 14(d) of the  Securities  Exchange  Act of 1934
("Act"), or any comparable successor provisions, of beneficial ownership (within
the  meaning of Rule 13d-3  promulgated  under the Act) of 30 percent or more of
either the  outstanding  shares of common stock or the combined  voting power of
the Corporation's then outstanding voting securities entitled to vote generally,
or the approval by the  stockholders  of the  Corporation  of a  reorganization,
merger, or  consolidation,  in each case, with respect to which persons who were
stockholders of the Corporation immediately prior to such reorganization, merger
or consolidation do not, immediately thereafter, own more than 50 percent of the
combined voting power entitled to vote generally in the election of directors of
the  reorganized,   merged  or  consolidated   Corporation's   then  outstanding
securities, or a liquidation or dissolution of the Corporation or of the sale of
all or substantially all of the Corporation's assets.

            Section 14.  Effective Date.

                        AGREEMENT TO DEFER BONUS PAYMENT

      This AGREEMENT TO DEFER BONUS PAYMENT (this "Agreement") is made effective
as of the 20th day of February  1998 between NL  Industries,  Inc., a New Jersey
corporation (the "Corporation") and J. Landis Martin ("Executive").

      WHEREAS,  Executive  was  awarded a Special  Bonus in  recognition  of his
performance which substantially contributed to the success of the Corporation;

      WHEREAS,  The  Corporation  and  Executive  desire  to  defer  payment  of
$1,508,300  (the "Deferred  Special Bonus") which  Executive,  in the absence of
this  Agreement,  would be  entitled  to  receive  immediately  with  respect to
services performed by Executive for the Corporation; and

      WHEREAS,  the Corporation and Robert D. Hardy as trustee,  will enter into
an agreement (the "Trust Agreement") which establishes an irrevocable trust (the
"Trust")  which is  intended  to hold and invest an amount of funds equal to the
Deferred  Special  Bonus until such bonus is paid to Executive  pursuant to this
Agreement;

      NOW,  THEREFORE,  in  consideration of the agreements set forth herein and
for other good and valuable consideration,  the receipt and sufficiency of which
is hereby acknowledged, the parties hereto agree as follows:

            1. The Deferred  Special  Bonus shall be paid to  Executive,  or his
designated  beneficiaries,  upon the earliest to occur of (a) the termination of
Executive's employment (including  Executive's  resignation) for any reason, (b)
Executive's  death,  or (c) such date as shall be determined  by the  Management
Development  and   Compensation   Committee  of  the  Board  of  Directors  (the
"Committee") in its sole discretion.

            2. The Deferred  Special  Bonus shall accrue  interest  beginning on
February 20, 1998 up to and  including the date such amount is paid to Executive
pursuant  to  Paragraph 1 hereof (the  "Deferred  Payment  Date") and the entire
amount of such accrued  interest  shall be paid to Executive,  or his designated
beneficiaries,  on the Deferred  Payment Date. Such interest shall accrue at the
rate of eight and one-half percent (8.50%) per annum.  Interest accrued pursuant
to this Paragraph 2 shall compound on a semi-annual  basis and shall be computed
for the actual  number of days elapsed on the basis of a year  consisting of 365
or 366 days.

            3. The Corporation  shall immediately enter into the Trust Agreement
and thereby  establish the Trust.  The  Corporation  shall  contribute an amount
equal to the Deferred Special Bonus to the Trust.

            4. Subject to the terms of the Trust Agreement,  the Corporation may
satisfy  its  payment   obligations   to   Executive,   or  to  his   designated
beneficiaries,  under this  Agreement by (a)  directing the Trustee to make such
payments from the principal and /or earnings of the Trust, (b)






making such payments directly from the  Corporation's  internal funds, or (c) by
any combination of (a) and (b),  provided that all payments to Executive,  or to
his  designated  beneficiaries,  pursuant  to this  Agreement  shall  be made in
immediately available funds.

            5. The Corporation shall withhold,  either from the Deferred Special
Bonus in the year such  amount is paid to  Executive  pursuant  to  Paragraph  1
hereof,  or from  any  salary,  bonus  or  other  compensatory  payment  made to
Executive as the Corporation in its sole discretion may determine,  such amounts
as is  required  by law to be  withheld  in 1996 or  after,  as the case may be,
pursuant to Code 3101 and 3121(v)(2) or successor provisions thereof.

            6. Title to and beneficial ownership of any assets,  whether cash or
investments  and  whether  held  by the  Corporation  or the  Trust,  which  the
Corporation may earmark to meet its payment  obligations to Executive under this
Agreement,  shall at all  times  remain  in the  Corporation  or the  Trust,  as
applicable,  and Executive and his designated  beneficiaries  shall not have any
property  interest  whatsoever in any specific  assets of the Corporation or the
Trust.  Any right of the  Executive or any of his  designated  beneficiaries  to
receive  payments from the Corporation  under this Agreement shall be no greater
than the right of any unsecured general creditor of the Corporation.

            7. The right of Executive  or any other person to any payment  under
this Agreement shall not be assigned, transferred,  pledged or encumbered except
by will or by the laws of descent and distribution.

            8. If the  Committee  shall find that any person to whom any payment
is payable under this Agreement is unable to care for his or her affairs because
of illness or  accident,  or is a minor,  any  payment due (unless a prior claim
therefor  shall  have  been made by a duly  appointed  guardian  or other  legal
representative)  may be paid to the  spouse,  a child,  a parent,  a brother  or
sister, or the person or persons designated by the Executive in writing,  or, in
the absence of any of the  foregoing,  to any one or more persons  deemed by the
Committee to be appropriate.  Any such payment shall be a complete  discharge of
the liabilities of the Corporation under this Agreement.

            9. Nothing  contained  herein shall be construed as conferring  upon
Executive the right to continue in the employ of the Corporation as an executive
or in any other capacity.

            10 This Agreement  shall be binding upon and inure to the benefit of
the  Corporation,  it successors  and assigns,  and the Executive and his heirs,
executors, administrators and legal representatives.

            11. This Agreement  contains the entire agreement of and between the
parties with respect to the subject  matter  hereof,  and  supersedes  any prior
understandings,  agreements,  or  representations  by or  between  the  parties,
written or oral, which may have related to the subject matter hereof in any way.
In the event of any conflict  between the terms and provisions of this Agreement
and the terms and  provisions of any employment or severance  agreement  entered
into by the parties  hereto,  the terms and provisions of this  Agreement  shall
govern.

                                      2





            12.  The  Agreement  shall be  governed  by the laws of the State of
Texas without giving effect to any choice of law or conflict of law provision or
rule (whether of the State of Texas or any other  jurisdiction) that would cause
the application of the laws of any jurisdiction other than the State of Texas.

                  *          *         *         *         *

            IN WITNESS WHEREOF,  the parties hereto have executed this Agreement
as of the date first written above.

                                 TRUST AGREEMENT


            This  Agreement  is made  effective  as of the 20th day of February,
1998 by and between NL Industries,  Inc. (the "Corporation") and Robert D. Hardy
(the "Trustee");

            WHEREAS, the Corporation and J. Landis Martin (the "Executive") have
entered into the  Agreement to Defer Bonus  Payment (the  "Deferral  Agreement")
attached hereto as Exhibit A;

            WHEREAS,  the Corporation has incurred or expects to incur liability
under the terms of such Deferral Agreement with respect to the Executive;

            WHEREAS,  the Corporation  wishes to establish a trust  (hereinafter
called the  "Trust")  and to  contribute  to the Trust assets that shall be held
therein,  subject to the claims of the  Corporation's  creditors in the event of
the Corporation's Insolvency, as herein defined, until paid to the Executive and
his  beneficiaries in such manner and at such times as specified in the Deferral
Agreement;

            WHEREAS,  it is the  intention  of the parties that this Trust shall
constitute  an  unfunded  arrangement  and shall not  affect  the  status of the
Deferral  Agreement as an unfunded plan  maintained for the purpose of providing
deferred  compensation  for a member of the select group of management or highly
compensated  employees for purposes of Title I of the Employee Retirement Income
Security Act of 1974;

            WHEREAS,   it  is  the   intention  of  the   Corporation   to  make
contributions to the Trust to provide itself with a source of funds to assist it
in the meeting of its liabilities under the Deferral Agreement;

            NOW, THEREFORE,  the parties do hereby establish the Trust and agree
that the Trust shall be comprised, held and disposed of as follows:

            Section 1.  Establishment of Trust

            (a) The  Corporation  hereby deposits with the Trustee in trust $100
or such other amount as  determined by the  Corporation,  which shall become the
principal of the Trust to be held,  administered  and disposed of by the Trustee
as provided in this Trust Agreement.

            (b) The Trust hereby established shall be irrevocable.

            (c) The  Trust is  intended  to be a  grantor  trust,  of which  the
Corporation is the grantor,  within the meaning of subpart E, part I, subchapter
J, chapter 1, subtitle A of the Internal  Revenue Code of 1986, as amended,  and
shall be construed accordingly.

            (d) The  principal of the Trust,  and any earnings  thereon shall be
held  separate and apart from other funds of the  Corporation  and shall be used
exclusively for the uses and purposes of

                                      1





the Executive and general  creditors as herein set forth.  The Executive and his
beneficiaries  shall have no  preferred  claim on, or any  beneficial  ownership
interest  in, any assets of the Trust.  Any rights  created  under the  Deferral
Agreement and this Trust Agreement shall be mere unsecured contractual rights of
the Executive and his beneficiaries against the Corporation.  Any assets held by
the Trust will be subject to the claims of the  Corporation's  general creditors
under  federal and state law in the event of  Insolvency,  as defined in Section
3(a) herein.

            (e) The Corporation shall make additional  deposits of cash or other
property in trust with the Trustee in accordance  with the terms of the Deferral
Agreement to augment the principal to be held,  administered  and disposed of by
the  Trustee as provided  in this Trust  Agreement.  Neither the Trustee nor the
Executive or any of his beneficiaries  shall have any right to compel additional
deposits, except as may be required by the terms of the Deferral Agreement.

            Section 2.  Payments to Executive and His Beneficiaries.

            (a) The Corporation  shall deliver to the Trustee a written schedule
(the "Payment  Schedule")  that indicates the amounts  payable in respect of the
Executive  (and his  beneficiaries),  that provides the amounts so payable,  the
form in which  such  amount is to be paid,  and the dates  for  payment  of such
amounts. Except as otherwise provided herein, the Trustee shall make payments to
the Executive and his  beneficiaries  in accordance with such Payment  Schedule.
The Corporation  may amend or modify such Payment  Schedule from time to time by
providing the Trustee with written  notice of such  amendments.  The Trustee may
conclusively rely on such Payment Schedule. The Trustee shall make provision for
the reporting and  withholding of any federal,  state or local taxes that may be
required to be withheld with respect to the payment of benefits  pursuant to the
terms  of  the  Deferral  Agreement  and  shall  pay  amounts  withheld  to  the
appropriate  taxing  authorities  or  determine  that  such  amounts  have  been
reported, withheld and paid by the Corporation.

            (b)  The  entitlement  of  the  Executive  or his  beneficiaries  to
benefits under the Deferral  Agreement shall be determined by the Corporation in
accordance  with the  terms of the  Deferral  Agreement,  and any claim for such
benefits  shall be  considered  and  reviewed  under the  terms of the  Deferral
Agreement.

            (c) The  Corporation  may make  payment of benefits  directly to the
Executive  or his  beneficiaries  as they  become  due  under  the  terms of the
Deferral Agreement.  The Corporation shall notify the Trustee of its decision to
make payment of benefits  directly  prior to the time amounts are payable to the
Executive or his beneficiaries. Such payments by the Corporation shall not amend
the Payment Schedule unless the Corporation specifically amends said Schedule in
writing.  In addition,  if the principal of the Trust, and any earnings thereon,
are not  sufficient to make payments of benefits in accordance  with the Payment
Schedule,  the  Corporation  shall make the  balance of each such  payment as it
falls due. The Trustee shall notify the Corporation where principal and earnings
are not sufficient.


                                      2





            Section  3.  Trustee  Responsibility  Regarding  Payments  to  Trust
            Beneficiary When the Corporation Is Insolvent.

            (a) The Trustee  shall not make any payments to the Executive or his
beneficiaries  if  the  Corporation  is  Insolvent.  Notwithstanding  any  other
provision of this Trust Agreement,  all determinations by the Trustee under this
Trust Agreement regarding whether the Corporation is solvent or Insolvent should
be  based  solely  on  the  written  representation  to  the  Trustee  from  the
Corporation's   Controller  or  Chief  Financial  Officer  without   independent
investigation by the Trustee.  The Corporation  shall be considered  "Insolvent"
for purposes of this Trust Agreement if (i) the Corporation is unable to pay its
debts as they  become  due,  or (ii) the  Corporation  is  subject  to a pending
proceeding as a debtor under the United States Bankruptcy Code.

            (b) At all times during the  continuance of this Trust,  as provided
in Section 1(d) hereof,  the  principal and income of the Trust shall be subject
to claims of general creditors of the Corporation under federal and state law as
set forth below.

                  (1) The Board of Directors,  the Chief Executive Officer,  the
Chief Financial Officer ("CFO") and the Controller of the Corporation shall have
the duty to inform the Trustee in writing of the  Corporation's  Insolvency with
respect to any payment date on the Payment Schedule.  If a person claiming to be
a  creditor  of the  Corporation  alleges in  writing  to the  Trustee  that the
Corporation  has become  Insolvent,  the  Trustee  shall  determine  whether the
Corporation  is  Insolvent;  such  determination  shall be made based  solely on
written  representation  from the  Corporation's  Controller or Chief  Financial
Officer. Pending such determination,  the Trustee shall not make any payments to
Executive or his beneficiaries.

                  (2)  Unless  the   Trustee  has   received   notice  from  the
Corporation that the Corporation is Insolvent, the Trustee shall have no duty at
any time to inquire whether the  Corporation is Insolvent.  The Trustee shall in
all  events  rely on such  representation  from  the  Corporation  in  making  a
determination concerning the Corporation's solvency.

                  (3) In the event that the  Corporation's  Controller  or Chief
Financial  Officer  has  notified  the  Trustee in writing of the  Corporation's
Insolvency,  the Trustee  shall not make any  payments to the  Executive  or his
beneficiaries  and shall  hold the  assets of the Trust for the  benefit  of the
Corporation's  general  creditors.  Nothing in this Trust Agreement shall in any
way  diminish  or impair any rights of the  Executive  or his  beneficiaries  to
pursue their  rights as general  creditors  of the  Corporation  with respect to
payments due under the Deferral Agreement or otherwise.

                  (4) The Trustee shall resume making  payments to the Executive
or his  beneficiaries  in accordance with Section 2 of this Trust Agreement only
after the Trustee has determined that the Corporation is not Insolvent (or is no
longer Insolvent).

            (c)  Provided  that  there are  sufficient  assets,  if the  Trustee
discontinues  making payments from the Trust pursuant to Section 3(b) hereof and
subsequently resumes such payments,

                                      3





the first  payment  following  such  discontinuance  shall include the aggregate
amount of all payments due to the Executive or his beneficiaries under the terms
of the  Deferral  Agreement  for the  period  of such  discontinuance,  less the
aggregate  amount of any payments made to the Executive or his  beneficiaries by
the Corporation in lieu of the payments  provided for hereunder  during any such
period of discontinuance.

            Section 4.  Payments to the Corporation.

            Except as provided in Section 3 hereof,  the Corporation  shall have
no right or power to direct  the  Trustee  to return  to the  Corporation  or to
divert to others any of the Trust assets  before all payments  have been made to
the  Executive  or his  beneficiaries  pursuant  to the  terms  of the  Deferral
Agreement.

            Section 5.  Investment Authority.

            In no event may the Trustee invest in securities (including stock or
rights to acquire stock) or obligations issued by the Corporation,  other than a
de  minimis  amount  held in common  investment  vehicles  in which the  Trustee
invests.  All rights  associated  with assets of the Trust  shall be  exercised,
solely in accordance with the directions of the  Corporation,  by the Trustee or
the person designated by the Trustee, and shall in no event be exercisable by or
rest with the Executive.

            Section 6.  Disposition of Income.

            During the term of this Trust, all income received by the Trust, net
of expenses and taxes, shall be accumulated and reinvested.

            Section 7.  Accounting by the Trustee.

            The  Trustee  shall  keep  records  of such  investments,  receipts,
disbursements,  and all  other  transactions  required  to be made,  as shall be
agreed upon in writing between the  Corporation and the Trustee.  Within 60 days
following  the close of each  calendar year and within 60 days after the removal
or  resignation of the Trustee,  the Trustee shall deliver to the  Corporation a
written  account of its  administration  of the Trust during such year or during
the period from the close of the last preceding year to the date of such removal
or resignation, setting forth all investments, receipts, disbursements and other
transactions  effected by it,  including a  description  of all  securities  and
investments  purchased and sold with the cost or net proceeds of such  purchases
or sales  (accrued  interest paid or  receivable  being shown  separately),  and
showing all cash,  securities and other property held in the Trust at the end of
such year or as of the date of such removal or resignation,  as the case may be.
In the event  the  Trustee  delegates  the  obligations  of this  section  to an
employee of the Corporation, such obligations shall be deemed to be fulfilled by
the Trustee.


                                      4





            Section 8.  Responsibility of the Trustee.

            (a) The  Trustee  shall  act  with the  care,  skill,  prudence  and
diligence under the  circumstances  then prevailing that a prudent person acting
in like  capacity and familiar  with such matters would use in the conduct of an
enterprise of a like character and with like aims, provided,  however,  that the
Trustee shall incur no liability to any person for any action taken  pursuant to
a  direction,  request  or  approval  given by the  Corporation  in  connection,
directly or indirectly, with, the terms of the Deferral Agreement or this Trust.
In the event of a dispute between the  Corporation and a party,  the Trustee may
apply to a court of competent jurisdiction to resolve the dispute.

            (b) The  Corporation  agrees  to  indemnify  and  hold  the  Trustee
harmless from any and all costs,  fees,  expenses  (including without limitation
attorney's  fees and  expenses),  claims or  lawsuits  by any  person or entity,
liabilities or obligations of any type or nature arising or related, directly or
indirectly,  to the Deferral  Agreement,  this Trust or any action or failure to
act by  the  Trustee  in  connection  in  any  way  with  any of the  foregoing.
Furthermore,  if the Trustee  undertakes  or defends any  litigation  arising in
connection  with this Trust,  the  Corporation  agrees to indemnify  the Trustee
against the  Trustee's  costs,  expenses  and  liabilities  (including,  without
limitation,  attorneys'  fees and  expenses)  relating  thereto and to be solely
liable for such payments.  If the Corporation does not pay such costs,  expenses
and  liabilities in a reasonably  timely manner,  the Trustee may obtain payment
from the Trust.

            (c) The  Trustee  may consult  with legal  counsel  (who may also be
counsel  for the  Corporation  generally)  with  respect to any of its duties or
obligations hereunder.

            (d) The Trustee may hire and the  Corporation  may make available to
the Trustee  agents,  accountants,  actuaries,  investment  advisors,  financial
consultants or other  professionals to assist it in performing any of its duties
or  obligations  hereunder.  In  addition,  the Trustee may  delegate any of its
duties under this Trust to employees and management of the  Corporation  and the
Trustee may  conclusively  rely on the reports of such  employees and management
without further investigation.

            (e) The Trustee shall have, without exclusion,  all powers conferred
on the Trustees by applicable law, unless expressly  provided  otherwise herein,
provided, however, that if an insurance policy is held as an asset of the Trust,
the Trustee shall have no power to name a  beneficiary  of the policy other than
the Trust,  to assign the policy (as distinct from conversion of the policy to a
different form) other than to a successor Trustee,  or to loan to any person the
proceeds of any borrowing against such policy.

            (f)  Notwithstanding  any powers granted to the Trustee  pursuant to
this Trust  Agreement or to applicable law, the Trustee shall not have any power
that could give this Trust the  objective of carrying on a business and dividing
the gains therefrom,  within the meaning of section  301.7701-2 of the Procedure
and  Administrative  Regulations  promulgated  pursuant to the Internal  Revenue
Code.

                                      5





            Section 9.  Compensation and Expenses of Trustee.

            The Corporation shall pay all  administrative and Trustee's fees and
expenses. If not so paid, the fees and expenses shall be paid from the Trust.

            Section 10.  Resignation and Removal of Trustee.

            (a) The  Trustee  may  resign at any time by  written  notice to the
Corporation,  which  shall be  effective  15 days after  receipt of such  notice
unless the Corporation and the Trustee agree otherwise.

            (b) The Trustee may be removed by the  Corporation on 15 days notice
to the Trustee or upon shorter notice accepted by the Trustee.

            (c) Upon a Change of Control, as defined herein, the Trustee may not
be removed by the Corporation for 18 months.

            (d) Upon  resignation or removal of the Trustee and appointment of a
successor Trustee, all assets shall subsequently be transferred to the successor
Trustee.  The transfer shall be completed within 30 days after receipt of notice
of resignation,  removal or transfer,  unless the  Corporation  extends the time
limit.

            (e) If the  Trustee  resigns or is  removed,  a  successor  shall be
appointed,  in  accordance  with  Section 11 hereof,  by the  effective  date of
resignation or removal under  paragraphs (a) or (b) of this section.  If no such
appointment  has been  made,  the  Trustee  may  apply  to a court of  competent
jurisdiction for appointment of a successor or for instructions. All expenses of
the Trustee in connection with the proceeding shall be allowed as administrative
expenses of the Trust.

            Section 11.  Appointment of Successor.

            (a) If the Trustee  resigns or is removed in accordance with Section
10(a) or (b) hereof, the Corporation may appoint any third party, such as a bank
trust  department or other party that may be granted  corporate  trustee  powers
under state law, as a successor  to replace  the  Trustee  upon  resignation  or
removal.  The appointment shall be effective when accepted in writing by the new
Trustee,  who shall have all of the  rights  and  powers of the former  Trustee,
including ownership rights in the Trust assets. The former Trustee shall execute
any  instrument  necessary or  reasonably  requested by the  Corporation  or the
successor Trustee to evidence the transfer.

            (b) The  successor  Trustee need not examine the records and acts of
any prior Trustee and may retain or dispose of existing Trust assets, subject to
Sections 7 and 8 hereof.  The successor Trustee shall not be responsible for and
the Corporation  shall indemnify and defend the successor Trustee from any claim
or liability  resulting from any action or inaction of any prior Trustee or from
any other past event, or any condition existing at the time it becomes successor
Trustee.

                                      6





            Section 12.  Amendment or Termination.

            (a) This Trust  Agreement  may be  amended  by a written  instrument
executed by the Trustee and the Corporation.  Notwithstanding the foregoing,  no
such amendment shall conflict with the terms of the Deferral  Agreement or shall
make the Trust revocable.

            (b) The  Trust  shall  not  terminate  until  the date on which  the
Executive and his  beneficiaries are no longer entitled to any payments pursuant
to the terms of the Deferral Agreement. Upon termination of the Trust any assets
remaining in the Trust shall be returned to the Corporation.

            Section 13.  Miscellaneous.

            (a) Any provision of this Trust Agreement prohibited by law shall be
ineffective  to the extent of any such  prohibition,  without  invalidating  the
remaining provisions hereof.

      and  relating  to  the  period  prior  to  the  Closing  Date)  and  (iii)
      post-retirement medical and/or life insurance benefits coverage of current
      or former non-bargaining unit Employees and their eligible dependents.


                         ARTICLE III.  PURCHASE PRICE

      3.1.  Unadjusted  Purchase Price. At the Closing,  in addition to assuming
the Assumed  Liabilities,  Purchaser  (together with the H&C Assignees) will pay
for the  Purchased  Assets  and the  covenants  of  Seller  included  herein  an
aggregate  purchase price in the amount of U.S.  $445,000,000  (the  "Unadjusted
Purchase  Price"),  subject to adjustment as provided in Section 3.2 and Section
10.6 (as adjusted, the "Purchase Price"). The Unadjusted Purchase Price shall be
paid by wire transfer of  immediately  available  funds to such account as shall
have  been  designated  by  Seller  to  Purchaser  prior to the  Closing.  In so
designating such account, Seller shall be acting as agent for RII and shall have
the  exclusive  responsibility  for the  delivery to RII of such  portion of the
Unadjusted Purchase Price to which it may be entitled.

      3.2.    Adjustments to the Purchase Price

              (a)  If  the  amount  of  the  Net  Book  Value  of  the  Business
(determined in accordance  with Section 3.2(b) as of the Closing  Statement Date
(as hereinafter defined) is: (i) less than $62,343,000,  the Unadjusted Purchase
Price shall be decreased by an amount equal to the amount by which such Net Book
Value is less than $62,343,000,  (the "Downward Book Value Adjustment"); or (ii)
is greater than $62,343,000, the Unadjusted Purchase Price shall be increased by
an amount  equal to the  amount by which  such Net Book  Value is  greater  than
$62,343,000,  but such increased amount shall not in any event exceed the amount
of cash and cash equivalents  included in the Closing  Statement plus $5,000,000
(the "Upward Book Value  Adjustment" and,  together with the Downward Book Value
Adjustment,  the "Book Value Adjustment").  Payment of any Book Value Adjustment
shall be made pursuant to Section 3.2(f).




                                     10











              (b) As used  herein,  the term "Net Book Value" shall mean the sum
of the  consolidated  assets of the Business  minus the sum of the amount of the
consolidated  liabilities of the Business as reflected on the Closing Statement,
(i)  provided  there shall be excluded  from the  consolidated  assets:  (A) any
Excluded Assets;  and, (B) any assets of the Acquired  Subsidiaries  relating to
Income Taxes and deferred Income Taxes with respect to the Business attributable
to periods ending on or prior to the Closing Date or to the pre-Closing  portion
of any taxable  period that includes but does not end on the Closing  Date;  and
(ii) provided there shall be excluded from the consolidated liabilities: (A) any
Retained  Liabilities  and  (B) any  liabilities  of the  Acquired  Subsidiaries
relating to Income Taxes and deferred  Income Taxes with respect to the business
attributable  to  periods  ending  on or  prior  to the  Closing  Date or to the
pre-Closing  portion of any taxable period that includes but does not end on the
Closing Date.

              (c) The term "Closing  Statement"  shall mean the statement of Net
Book Value as of the Closing  Date or, if the Closing  Date does not fall on the
last business day of the month,  as of the month-end  following the Closing Date
(as applicable,  the "Closing  Statement Date").  The Closing Statement shall be
prepared  by  Purchaser  and  shall  be  delivered  to  Seller  as  promptly  as
practicable,  and in any event within 60 days after the Closing  Statement Date.
The Closing  Statement  (i) shall be prepared in  accordance  with United States
generally accepted accounting principles ("GAAP") applied in a manner consistent
with the  application  of those  principles in the audited  balance sheet of the
Seller and its  Subsidiaries  as of  December  31,  1996 and (ii) shall  present
fairly the Net Book Value as of the Closing Statement Date and the amount of the
Book Value Adjustment resulting therefrom;  provided,  however,  that no prepaid
expense  shall be  included  on the  Closing  Statement  unless  Purchaser  will
actually  realize the  benefit  thereof  subsequent  to the  Closing  Date.  For
illustrative purposes, set forth on Schedule 3.2(b) hereof is calculation of the
projected Net Book Value of the Business as of December 31, 1997.

              (d) If the  Closing  Date  occurs on any date  other than the last
business day of the month,  then the Book Value Adjustment shall be decreased by
an  amount  equal to the  "Profit  Adjustment"  as  defined  below.  The  Profit
Adjustment  shall be  calculated by using the  Consolidated  Statement of Income
(which will be present in the form set out in Schedule  3.2(d)) for the month in
which the Closing Date occurs (the "Closing Month"). Purchaser shall prepare the
Consolidated Statement of Income in accordance with GAAP and consistent with the
principles applied in the audited  consolidated  financial  statements of Seller
and its  Subsidiaries  for  the  year  ended  December  31,  1996.  The  "Profit
Adjustment" shall be the amount obtained by taking the net income (as set out in
the  Consolidated  Statement of Income) for the Closing Month  multiplied by the
adjustment  factor.  The  adjustment  factor will be calculated as the number of
days from the Closing Date to and including the Closing  Statement  Date divided
by the total number of days in the Closing Month.




                                     11











              (e) Seller shall have the  opportunity to examine the work papers,
schedules,  and other  documents  prepared by Purchaser,  in connection with its
preparation of the Closing Statement and Profit Adjustment,  as applicable.  The
Closing  Statement  and  Profit  Adjustment  shall be final and  binding  on the
parties  unless,  within 60 days after delivery to Seller notice is given by the
Seller  of its  objection  setting  forth in  reasonable  detail  its  basis for
objection.  If notice of objection is given, the parties shall consult with each
other with  respect to the items in dispute.  If the parties are unable to reach
agreement within 20 days after the notice of objection has been given, the items
in dispute shall be referred for resolution to the U.S.  national office of KPMG
Peat Marwick LLP (the "Accountants") as promptly as practicable. The Accountants
will  make  a  determination  as  to  each  of  the  items  in  dispute,   which
determination  will be (i) in  writing,  (ii)  furnished  to each of the parties
hereto as promptly as practicable  after the items in dispute have been referred
to the  Accountants,  (iii) made in  accordance  with this  Agreement,  and (iv)
conclusive and binding upon each of the parties hereto. In connection with their
determination  of the disputed items,  the Accountants  will be entitled to rely
on, if any, the workpapers,  trial balances,  and similar materials  prepared by
Purchaser's auditors in connection with such firm's examination of the financial
statements of Seller and Purchaser, and the fees and expenses of the Accountants
will be shared by Purchaser and Seller in such  proportions  as the  Accountants
determine and deem equitable (after taking into account, among other things, the
difference  between  the  positions  taken  by  Purchaser  and  Seller,  and the
conclusion  determined by the Accountants to be appropriate).  Each of Purchaser
and Seller will use commercially  reasonable efforts to cause the Accountants to
render  their  decision as soon as  reasonably  practicable,  including  without
limitation by promptly complying with all reasonable requests by the Accountants
for information, books, records, and similar items.

              (f) Parent and Seller jointly and severally  agree,  within 5 days
after the date of  determination  of the Book  Value  Adjustment  and the Profit
Adjustment,  to pay to Purchaser (or to the H&C Assignees,  as  applicable)  the
amount of any Downward Book Value  Adjustment,  plus  interest  thereon from the
Closing  Statement Date to the date of  determination  at a rate of five percent
(5%) per annum  (subject to applicable  withholding  Taxes as may be required by
Law), accruing daily and compounding  annually, as an adjustment to the Purchase
Price  by wire  transfer  of  immediately  available  funds to such  account  or
accounts as shall be designated by Purchaser to Seller.  Purchaser,  H&C and H&C
America  jointly  and  severally  agree,   within  5  days  after  the  date  of
determination of the Book Value  Adjustment,  to pay (or cause to be paid in the
case of the  H&C  Assignees)  to  Seller  (or to  such  Persons  as  Seller  may
designate) the amount of any Upward Book Value Adjustment, plus interest thereon
from the Closing  Statement Date to the date of  determination at a rate of five
percent  (5%) per  annum  (subject  to  applicable  withholding  Taxes as may be
required by Law), accruing daily and compounding  annually,  as an adjustment to
the  Purchase  Price by wire  transfer of  immediately  available  funds to such
account or accounts as shall be designated by Seller to Purchaser.




                                     12











      3.3.  Allocation of Purchase  Price.  Seller and Purchaser  agree that the
Unadjusted  Purchase Price shall be allocated to and among the shares of capital
stock of the Acquired  Subsidiaries as set forth on Schedule 3.3 hereof.  Seller
and Purchaser agree that the remaining portion of the Unadjusted  Purchase Price
of the Purchased Assets  (including the amount of the Assumed  Liabilities) will
be allocated  among the Purchased  Assets and the covenants of Parent and Seller
included  herein  within  60  Business  Days  after the  Closing  Date by mutual
agreement  between  Purchaser  and Seller,  and Purchaser and Seller agree to be
bound by such allocation.  Such allocation shall comply with Section 1060 of the
Internal Revenue Code of 1986, as amended (the "Code"), and Treasury Regulations
promulgated  thereunder.  Subject to the requirements of any applicable tax law,
all Tax Returns and reports including,  without limitation, IRS form 8594, filed
by the  Purchaser  and the  Seller  shall be  prepared  consistently  with  such
allocation  and  neither  the  Purchaser  nor the  Seller  shall take a position
contrary thereto. In the event of any purchase price adjustment  hereunder,  the
Purchaser  (and the H&C  Assignees,  as the case may be) and the Seller agree to
adjust such  allocation to reflect such purchase  price  adjustment  and to file
consistently any tax returns and reports including, without limitation, IRS form
8594,  required as a result of such  purchase  price  adjustment.  Any  disputes
regarding  the  allocation  of the  Unadjusted  Purchase  Price of the Purchased
Assets and the Assumed  Liabilities  shall be  referred  for  resolution  to the
Accountants,  and the fees and  expenses  of the  Accountants  will be shared by
Purchaser and Seller in such  proportions as the Accountants  determine and deem
equitable  (after  taking into  account,  among other  matters,  the  difference
between the allocation proposed by Seller and Purchaser,  respectively,  and the
allocation  determined by the Accountants to be appropriate).  Each of Purchaser
and Seller will use commercially  reasonable efforts to cause the Accountants to
render  their  decision as soon as  reasonably  practicable,  including  without
limitation by promptly complying with all reasonable requests by the Accountants
for information, books, records, and similar items.


                           ARTICLE IV.  THE CLOSING

      4.1.  Date of Closing.  The  consummation  of the purchase and sale of the
Purchased Assets contemplated hereby (the "Closing") shall take place on January
30, 1998, at the offices of Weil,  Gotshal & Manges LLP, 767 Fifth  Avenue,  New
York, New York 10155 (or at such other place as the parties may designate) or on
such  other  date  designated  by the  parties  in  writing,  after  each of the
conditions  specified in Article VII has been  fulfilled (or waived by the party
entitled to waive that condition).  The date on which the Closing is effected is
referred to in this Agreement as the "Closing Date." At the Closing, the parties
shall execute and deliver the documents referred to in Article VIII.





                                     13

lease, or otherwise hold the Purchased Assets owned,  leased,  or otherwise held

described on Schedule 5.1.1, each of Seller and RII is in good standing and duly
qualified  to conduct  business as a foreign  corporation  in every state of the
United  States in which its  ownership  or lease of  property  or conduct of its
business activities makes such qualification necessary, except where the failure
to be so qualified would not, individually or in the aggregate,  have a material
adverse effect on the Purchased Assets or the condition (financial or otherwise)
or results of operations of the Business, taken as a whole, or on the ability of
Purchaser to conduct the Business after the Closing ("Material Adverse Effect").
The states in which  Seller  and RII are so  qualified  are  listed on  Schedule
5.1.1.

              5.1.2.A  Acquired  Subsidiaries  and Enenco.  Each of the Acquired

Subsidiaries and Enenco has the requisite  corporate power and authority to own,
lease, or otherwise hold the assets owned,  leased,  or otherwise held by it and

Subsidiaries  has  filed in the last ten  years for  bankruptcy  or  composition
proceedings.  Except as  described  on  Schedule  5.1.2A,  each of the  Acquired
Subsidiaries  and  Enenco is duly  qualified  to conduct  business  as a foreign
corporation in each  jurisdiction in which its ownership or lease of property or
assets or the  conduct  of its  business  activities  makes  such  qualification
necessary,  except where the failure to be so qualified would not,  individually
or in the aggregate,  have a Material Adverse Effect. The jurisdictions in which
the Acquired Subsidiaries are so qualified are listed on Schedule 5.1.2A. Except
for the  Subsidiaries  and Enenco,  and except as otherwise set forth in Section
1.2.10 and on Schedule 5.1.2A,  no shares of any corporation or any ownership or
other investment interest, either of record, beneficially,  or equitably, in any
association,  partnership,  joint venture,  limited liability company, trust, or
other legal entity are owned or held, directly or indirectly, by Seller or RII.



                                     14

the  Enenco  Shares  are free and  clear of all  Liens.  Except  as set forth on
Schedule  5.1.2B,  there are no outstanding  securities,  rights  (preemptive or
other), subscriptions, calls, warrants, options, or other agreements (except for
this  Agreement)  that give any person the right to purchase,  subscribe for, or
otherwise  receive  or be issued any  shares of  capital  stock of any  Acquired
Subsidiary  or  Enenco  or any  security  convertible  into or  exchangeable  or
exercisable  for any  shares of  capital  stock of any  Acquired  Subsidiary  or
Enenco.  Except  as  set  forth  on  Schedule  5.1.2B,  there  are  no  proxies,
stockholder agreements,  voting trusts, or other agreements or understandings to

bound  relating  to the voting of any shares of  capital  stock of any  Acquired
Subsidiary  or Enenco  and,  except for rights  held by Parent,  Seller,  or any

Parent has the requisite  corporate  power to execute and deliver this Agreement
and the  agreements  to be entered into by them at the Closing  pursuant  hereto
(the "Seller Ancillary Documents") and to perform the transactions  contemplated
hereby and thereby to be performed by it. The  execution and delivery by each of
Seller and Parent of this Agreement and the Seller  Ancillary  Documents and the
performance by each of them of the transactions  contemplated hereby and thereby
to be  performed  by it  have  been  or,  in the  case of the  Seller  Ancillary
Documents, will at the Closing be duly authorized by any necessary corporate and
shareholder  action on the part of Seller and Parent.  This  Agreement has been,
and each Seller  Ancillary  Document  will at the Closing be, duly  executed and
delivered by duly authorized officers of each of Seller and Parent and, assuming
the due execution and delivery of this Agreement and, as applicable,  any Seller
Ancillary Document, by Purchaser,  constitutes a valid and binding obligation of
Seller and Parent enforceable  against them in accordance with its terms, except
as may be limited by  bankruptcy,  insolvency,  reorganization,  moratorium,  or
other similar laws affecting the enforcement of creditors' rights in general and

                                     15











              5.1.4.  No  Restrictions  Against  Sale of the  Purchased  Assets;
Required Consents.  The execution and delivery of this Agreement and each Seller
Ancillary  Document  by Seller or Parent  does not or, in the case of the Seller
Ancillary  Documents,  will not, and the performance by Seller,  Parent,  or any
Subsidiary of the transactions contemplated hereby or thereby to be performed by
any of them will not (a) conflict  with or violate any provision of the articles
or certificate of incorporation or by-laws (or other  organizational  documents)
of Seller, Parent, any Subsidiary, or Enenco (b) except as set forth on Schedule
5.1.4,  conflict  with,  or result in any  violation of, or constitute a default
(with or  without  notice or lapse of time,  or both)  under,  or give rise to a
right of termination, cancellation, or acceleration of any obligation or to loss
of a benefit  under,  any  provision  of any  Contract or Permit to which any of
Seller, Parent, any Subsidiary,  or Enenco is a party or by which any of them or
any of their respective  properties are bound, (c) constitute a violation of any
Law  applicable to any of Seller,  Parent,  any  Subsidiary,  or Enenco,  or the
Purchased  Assets,  or (d) result in the  creation  of any Lien  (other than any
Permitted Lien) upon any of the Purchased Assets,  except in the case of clauses
(b)  or  (c)  above,  for  such  conflicts,   violations,   breaches,  defaults,
accelerations,  terminations,  modifications,  or cancellations  that would not,
individually  or in the  aggregate,  (i) have a Material  Adverse  Effect,  (ii)
materially  impair the  ability of Parent or Seller to perform  its  obligations
hereunder or under any Seller Ancillary Document, or (iii) prevent or materially
delay  the  consummation  of the  purchase  and  sale  of the  Purchased  Assets
contemplated  hereby.  No consent,  approval,  order,  or  authorization  of, or
registration,  declaration,  or filing with, any Governmental Entity is required
to be obtained or made by or with respect to Seller, Parent, any Subsidiary,  or
Enenco in connection  with the  execution and delivery of this  Agreement or any
Seller  Ancillary  Document  by  Seller,   Parent,  or  any  Subsidiary  or  the
performance  by  Seller,   Parent,   or  any  Subsidiary  of  the   transactions
contemplated  hereby to be performed  by either of them,  except for (i) such of
the foregoing as are listed or described on Schedule 5.1.4 and (ii) any filings,
if  required,  with the  Federal  Trade  Commission  and  Department  of Justice
pursuant to the Hart-Scott-Rodino Antitrust Improvements Act of 1976, as amended
(the "HSR Act").

              5.1.5.  No Third Party  Options.  Except as  described on Schedule
5.1.5,  there  are no  existing  agreements  with,  options,  or  rights  of, or
commitments to any Person to acquire any of the Purchased Assets or any interest
therein,  except  for  those  Contracts  entered  into in the  normal  course of
business consistent with past practice.

              5.1.6.A  Seller  Financial  Statements.  Seller has  delivered  to
Purchaser  true and complete  copies of (a) the  consolidated  balance sheets of
Seller and its Subsidiaries at December 31, 1994, 1995, and 1996 and the related
statements of income, changes in stockholder's equity (deficit),  and cash flows
for the fiscal  years then ended,  audited by Coopers & Lybrand  LLP; and (b) an
unaudited balance sheet of Seller and its consolidated Subsidiaries at September
30, 1997 and  related  statements  of income,  changes in  stockholder's  equity
(deficit),  and  cash  flows  for  the  period  then  ended  (collectively,  the
"Financial



                                     16











Statements").  Except as set forth on Schedule 5.1.6, such Financial  Statements
have been prepared in accordance  with GAAP and such balance  sheets,  including
the  related  notes,  fairly  present  the  financial   position,   assets,  and
liabilities of Seller and its  consolidated  Subsidiaries at the dates indicated
and such statements of income,  changes in stockholder's  equity (deficit),  and
cash flow fairly  present the results of  operations,  changes in  stockholder's
equity (deficit), and cash flow of Seller and its consolidated  Subsidiaries for
the  periods  indicated;   provided,   however,  that  the  unaudited  financial
statements  included in the Financial  Statements are subject to normal year-end
adjustments (none of which  individually or in the aggregate could reasonably be
expected to have a Material Adverse Effect). References in this Agreement to the
"Interim  Balance  Sheet"  shall mean the  balance  sheet of the  Business as of
September 30, 1997 referred to above,  and  references in this  Agreement to the
"Interim Balance Sheet Date" shall be deemed to refer to September 30, 1997. The
books,  records,  and accounts of Seller and its  Subsidiaries  maintained  with
respect to the Business fairly reflect,  in reasonable  detail, the transactions
and the assets and  liabilities of Seller and its  Subsidiaries  with respect to
the  Business.  Neither  Seller nor RII has engaged in any material  transaction
with respect to the Business,  maintained any bank account for the Business,  or
used any of the funds of Seller or any Subsidiary in the conduct of the Business
except  for  transactions,  bank  accounts,  and funds  which  have been and are
reflected in the normally maintained books and records of the Business.

              5.1.6.B  Enenco  Financial  Statements.  Seller has  delivered  to
Purchaser  true and complete  copies of (a) the  consolidated  balance sheets of
Enenco at December 31, 1994, 1995, and 1996 and the related statements of income
and retained earnings and cash flows for the fiscal years then ended, audited by
Ernst & Young LLP ("Audited Enenco Financial Statements");  and (b) an unaudited
balance sheet of Enenco at September  30, 1997 and related  statements of income
and retained  earnings  and cash flows for the period then ended.  Except as set
forth on Schedule  5.1.6.B.,  to the actual  knowledge of Debbie  Young  without
inquiry,  there is no  reason to  believe  that such  Audited  Enenco  Financial
Statements  have not been  prepared  in  accordance  with GAAP and such  balance
sheets,  including  the  related  notes,  do not fairly  present  the  financial
position,  assets,  and  liabilities  of Enenco at the dates  indicated and such
statements of income and retained  earnings and cash flows do not fairly present
the results of operations and retained earnings and cash flows of Enenco for the
periods indicated.

              5.1.7. Accounts Receivable.  The accounts receivable of Seller and
its  Subsidiaries  arising from the Business as set forth on the Interim Balance
Sheet or arising since the date thereof are valid; and have arisen solely out of
bona fide sales and  deliveries  of goods,  performance  of services,  and other
business  transactions in the ordinary  course of business  consistent with past
practice.




                                     17











              5.1.8.  Inventory.  All  Inventory of Seller and its  Subsidiaries
used in the conduct of the Business, including without limitation raw materials,
work-in process,  and finished goods,  reflected on the Interim Balance Sheet or
acquired  since the date  thereof was acquired  and has been  maintained  in the
ordinary course of the Business; is of good and merchantable  quality;  consists
substantially of a quality, quantity, and condition usable, leasable or saleable
in the ordinary course of the Business;  and, net of related inventory valuation
reserves,  is valued  at the lower of cost or  market.  Except as  described  on
Schedule  5.1.8,  neither  Seller nor any Subsidiary is under any liability with
respect to the return of Inventory in the possession of wholesalers,  retailers,
or other customers.

              5.1.9. Absence of Undisclosed Liabilities.  Except as set forth on
Schedule  5.1.9,  to the knowledge of Parent or Seller,  neither  Seller nor any
Subsidiary  has any  liabilities  with respect to the Business  except (a) those
liabilities  set forth on the Interim  Balance Sheet and not heretofore  paid or
discharged and (b) those liabilities incurred in the ordinary course of business
consistent with past practice since the Interim Balance Sheet Date.

developed,  or offered for sale or license by Seller or RII in  connection  with
the conduct of the Business as presently conducted,  except the Excluded Assets;
provided,  however,  that such  representations  and warranties  with respect to
Intellectual Property are provided in Section 5.1.12(a) above. All the Purchased
Assets  and all of the  assets  held or  used  by the  Subsidiaries  are in good

              5.1.14.Real Property.

              (a) Title to Owned Real Property.  At Closing,  title to the Owned
Real Property and to all real property  owned by the Acquired  Subsidiaries  and
Enenco listed and described on Schedule 5.1.14(a), together with all appurtenant
easements  thereunto and all  structures,  fixtures,  and  improvements  located
thereon,  and any  minerals and mining  rights with respect  thereto (the "Other
Owned Real Property") shall be good and marketable,  free and clear of all Liens
and other matters affecting Seller's,  the Subsidiaries' or Enenco's title to or
possession of such Owned Real Property and other Owned Real Property, including,
but  not  limited  to,  all   encroachments,   boundary   disputes,   covenants,
restrictions,   burdens,  conditions,  servitudes,  occupancy  rights,  charges,
diligences,  easements,  rights of way, mortgages,  security interests,  leases,
encumbrances and title  objections,  excepting only the Permitted Liens and such
easements,  restrictions,  and covenants  presently of record,  which easements,
restrictions,  and covenants are listed on Schedule 5.1.14(a).  Without limiting
the  generality  of the  foregoing,  to Parent's  and  Seller's  knowledge,  all
unpatented  mining  claims  included in the Owned Real  Property are believed by
Seller to be  properly  located,  have  been  properly  maintained,  and in good
standing. At Closing, (i) title to the Owned Real Property shall be insurable by
Lawyers Title Insurance Company, pursuant to the most recent version of the ALTA
Owner's form of policy, and (ii) title to the Other Owned Real Property owned by
the Acquired  Subsidiaries (to the extent available in the country in which such
Other Owned Real  Property is located)  shall be insurable by a title  insurance
company selected by Purchaser



                                     22











pursuant to such  owner's form of policy as is customary in such country at such
insurer's  customary  rates,  in each case  free of all  exceptions  except  the
aforesaid easements,  restrictions, and covenants; provided that, in the case of
each  of the  foregoing  clauses  (i)  and  (ii),  Parent  and  Seller  make  no
representation as to the availability of such title insurance to the extent that
Purchaser  seeks to obtain  title  insurance in an amount and scope that is more
comprehensive  in the  aggregate  than the  title  insurance  obtained  by Chase
Manhattan Bank pursuant to the title policies listed on Schedule 5.1.14(a).

              (b) Leased Real Property. With respect to the Leased Real Property
and all real property  leased by any Acquired  Subsidiary and Enenco (the "Other
Leased Real  Property"  and,  together with the Other Owned Real  Property,  the
"Other Real Property"):

                        (i)Schedule 5.1.14(b) describes each Real Property Lease
      and each lease with respect to the Other Leased Real Property ("Other Real
      Property  Leases") by listing the name of the landlord or  sublandlord,  a
      description of the leased  premises,  and the  commencement and expiration
      dates of the current term;

                       (ii)each Real Property Lease and each Other Real Property
      Lease is, and at Closing shall be, in full force and effect and, except as
      contemplated  hereby, has not been assigned,  modified,  supplemented,  or
      amended,  and none of  Seller,  the  Subsidiaries  or Enenco is in default
      (with or without  notice or lapse of time,  or both) under any of the Real
      Property Leases or Other Real Property Leases; and

                     (iii)the   applicable  Acquired  Subsidiary  has  good  and
      marketable  title  to the  real  property  lease  located  in  Livingston,
      Scotland.

              (c) Utility Services. The water, electric,  gas, and sewer utility
services and the septic tank and storm drainage  facilities  currently available
to each  material  parcel of the Real  Property  and  Other  Real  Property  are
adequate  for the present use of the Real  Property  and Other Real  Property by
Seller, the Subsidiaries,  and Enenco, are not being appropriated by Seller, any
Subsidiary, or Enenco but rather are being supplied to Seller, the Subsidiaries,
and Enenco by utility  companies  or  municipalities,  and to the  knowledge  of
Parent and Seller there is no condition  which could  reasonably  be expected to
result in the  termination  of the present  access from the Real Property or the
Other Real Property to such utility services and other facilities,  except where
the termination would not have a Material Adverse Effect.

              (d) Assessments or Hazards.  None of Seller,  any  Subsidiary,  or
Enenco has received any written  notices from any  Governmental  Entity that the
assessed  value of any  material  parcel  of the  Real  Property  or Other  Real
Property  has been  determined  to be  materially  greater  than that upon which
county, township or school tax was paid for the 1996



                                     23











tax year applicable to each such tax, or, within past twelve months,  in writing
from any insurance carrier of Seller, any Subsidiary,  or Enenco of fire hazards
with respect to the Real Property or Other Real Property, except as set forth on
Schedule 5.1.14 hereto.

              (e) Eminent Domain. None of Seller, any Subsidiary,  or Enenco has
received any written  notices from any  Governmental  Entity having the power of
eminent  domain  over the Real  Property  or the Other Real  Property  that such
Governmental  Entity has  commenced  or intends to exercise the power of eminent
domain or a similar  power with respect to all or any material  part of the Real
Property or Other Real Property.

              (f) No Violations. To the knowledge of Seller and Parent, the Real
Property or Other Real  Property  and the  present  uses  thereof  comply in all
material respects with all applicable Laws, and none of Seller,  any Subsidiary,
or Enenco has received any written notices from any Governmental Entity that the
Real  Property  or Other Real  Property or any  improvements  erected or situate
thereon, or the uses conducted thereon or therein,  violate any applicable Laws,
except for  violations  that could not reasonably be expected to have a Material
Adverse Effect.

              (g) Flood Plain. To the knowledge of Seller and Parent, and except
as set forth on Schedule  5.1.14(g),  no material  part of the Real  Property or
Other Real Property (other than the Hightstown  leased  property)  contains,  is
located  within,  or abuts any flood plain,  navigable  water,  or other body of
water,  tideland,  wetland,  marshland,  or any other  area  which is subject to
special state, federal, or municipal regulation, control, or protection.

              5.1.15.Insurance.  Set forth in  Schedule  5.1.15 is a list of all
fire, liability,  and other forms of insurance and all fidelity bonds held by or
applicable to Seller, the Subsidiaries,  the Purchased Assets, the Business,  or
Enenco setting forth,  in respect of each such policy,  the policy name,  policy
number,  carrier, term, type of coverage, and annual premium. Except as noted on
Schedule 5.1.15,  all such insurance will remain, to the knowledge of Seller and
Parent,  in full force and effect with  respect to periods  before the  Closing;
provided,  that Parent and Seller will continue to pay premiums on policies held
by or  applicable  to Seller  and RII when due and will not  otherwise  take any
action to modify or cancel any such  insurance  policies  except for renewals or
replacements  of such policies made in the ordinary  course of business.  To the
knowledge  of Seller  and  Parent,  no event has  occurred,  including,  without
limitation,  the  failure by  Seller,  or any  Subsidiary  or Enenco to give any
notice or information or Seller, any Subsidiary, or Enenco giving any inaccurate
or  erroneous  notice or  information,  which  materially  limits or impairs the
rights of Seller, such Subsidiary, or Enenco under any such insurance policies.




                                     24

Purchaser  reasonable  access,  after  consultation  with Seller,  during normal
business hours to the employees, the Purchased Assets, facilities, and the books
and  records of Seller and its  Subsidiaries  so as to afford  Purchaser  a full
opportunity to make such review, examination,  and investigation of the Business
as Purchaser may desire to make,  including without  limitation an environmental
evaluation of Seller and its Subsidiaries  reasonably satisfactory to Seller and
Parent.  Purchaser  will be permitted to make extracts from or to make copies of
such books and records as may be reasonably  necessary in connection  therewith.

Subsidiaries to:

              (a) not fail to pay or discharge when due any liabilities of which

              (h) not take or omit to take any  action  as a result of which any

      such shares; and

      6.3.    Notification.

              (a) Parent and Seller shall provide  prompt written notice to H&C,
H&C America and  Purchaser,  and H&C, H&C America and  Purchaser  shall  provide
prompt  written  notice to Parent  and  Seller  (in each case  within 5 business
days), of any litigation,  arbitration, or administrative proceeding pending or,
to its knowledge,  threatened against Parent, Seller, or any Subsidiary,  on the
one hand, or H&C, H&C America, or Purchaser, on the other hand, which challenges
the transactions contemplated hereby.

              (b) Parent and Seller will promptly notify Purchaser (in any event
within 15 business  days) of any  development  or upon  learning  of  additional
information  causing or which  constitutes or would at the Closing  constitute a
breach of any of its representations and warranties  contained in Sections 5.1.4
through 5.1.25 above. Unless Purchaser has the right to terminate this Agreement
pursuant to Section 11.1 below by reason of the  development or information  and
exercises  that right  pursuant to such Section 11.1 below,  the written  notice
pursuant  to  this  Section   6.3(b)  will  be  deemed  to  have  qualified  the
representations  and  warranties  as to which such notice  relates,  and to have
cured any  misrepresentation  or breach of warranty  that  otherwise  might have
existed hereunder by reason of the development.

              (c) Each Party will give prompt  written notice to the other Party
of any material adverse development causing or which constitutes a breach of any
of its own  representations  and  warranties in Sections 5.1.1 through 5.1.3 and
5.2.1 through 5.2.3 above.  No disclosure by any party  pursuant to this Section
6.3(c),  however,  shall be deemed to amend or supplement the representations or
warranties of that Party or to prevent or cure any  misrepresentation  or breach
of warranty.

      6.4. Governmental Filings. Each of H&C, H&C America, and Purchaser, on the
one hand,  and  Parent and  Seller,  on the other  hand,  shall as  promptly  as
practicable  following the execution and delivery of this  Agreement,  file with
the United States Federal Trade  Commission and the United States  Department of
Justice,  the  notification  and report form under the HSR Act  required for the
transactions  contemplated hereby and any supplemental  information requested in
connection  therewith  pursuant  to the HSR Act.  Each of H&C,  H&C  America and
Purchaser,  on the one hand, and Parent and Seller,  on the other hand, shall as
promptly  as  practicable  comply  with any other  Laws of any  country  and the
European  Union which are  applicable  to any of the  transactions  contemplated
hereby and pursuant to which any consent,  approval, order, or authorization of,
or  registration,  declaration,  or filing with any  Governmental  Entity or any
other Person in connection with such transactions is necessary. Each of H&C, H&C
America and  Purchaser,  on the one hand,  and Parent and  Seller,  on the other
hand,  shall  furnish to the other such  necessary  information  and  reasonable
assistance as



                                     38











the  other  may  request  in  connection  with its  preparation  of any  filing,
registration,  or declaration  which is necessary under the HSR Act or any other
such Laws.  Each of H&C, H&C America and Purchaser,  on the one hand, and Parent
and Seller,  on the other hand,  shall keep each other apprised of the status of
any   communications   with,  and  any  inquiries  or  requests  for  additional
information  from, any Governmental  Entity,  and shall comply promptly with any
such inquiry or request.

      6.5. Third Party Consents. Each of H&C, H&C America, and Purchaser, on the
one hand, and Parent and Seller, on the other hand, will cooperate and use their
respective  commercially reasonable efforts to obtain as promptly as practicable
all consents,  approvals,  and waivers required by third Persons to transfer the
Purchased  Assets  (including  the  Contracts,  the Leased  Real  Property,  the
Permits, the Environmental  Permits, and the Intellectual Property) to Purchaser
in a manner that will avoid any default,  conflict,  or termination of rights in
respect thereof.

      6.6.  Compliance  with  Industrial  Site Recovery Act.  Seller will comply
promptly with all requirements of the Industrial Site Recovery Act ("ISRA"),  NJ
Stat. Ann. SS 13:1K-7 et seq., in connection with the transactions  contemplated
by  this  Agreement  as  may  be  required  by  the  New  Jersey  Department  of
Environmental Protection ("NJDEP") and shall take all actions necessary to cause
the transaction  contemplated hereby to be effected in compliance with ISRA. The
Seller, after consultation with Purchaser,  will determine which actions must be
taken prior to or after the Closing to comply  with ISRA,  it being  agreed that
the scope,  extent,  and method of such actions are matters to be agreed upon by
and between Seller (after  consultation with Purchaser) and the NJDEP,  provided
that such actions do not  unreasonably  interfere with the use of the facilities
by Purchaser.  Seller will provide  Purchaser with any documents to be submitted
to the NJDEP in a reasonable time (in any event within five days or such shorter
period necessary to meet the deadlines of NJDEP) prior to submission.  All costs
and  expenses  incurred  in  connection  with  compliance  with ISRA,  including
reasonable  attorneys fees,  engineering and other  professional or expert fees,
prior to or after the Closing  will be borne solely and  exclusively  by Seller.
From and after the Closing Date,  Purchaser  will cooperate with Seller and will
provide  Seller  access  to the  facilities  at  reasonable  times  in  order to
accomplish  any actions  required to comply with ISRA, in  connection  with this
transaction, or in connection with ECRA/ISRA Case No. 86917.

      6.7. Confidentiality.  Each of H&C, H&C America, and Purchaser, on the one
hand,  and Parent and Seller,  on the other hand,  shall keep  confidential  all
information  obtained by it or them with respect to the other in connection with
this Agreement and the negotiations preceding this Agreement,  and will use such
information  solely in connection  with the  transactions  contemplated  by this
Agreement, and if the transactions contemplated hereby are not consummated, each
shall,  upon  request,  return to the other or destroy (and certify to the other
that it has so  destroyed),  without  retaining a copy thereof,  any  schedules,
documents, or



                                     39











other written  information,  and any reports,  notes,  computer  files, or other
evidence, whether written or electronic,  that reflect, refer to or contain such
information  obtained from the other in connection  with this  Agreement and the
transactions contemplated hereby.  Notwithstanding the foregoing, no party shall
be required to keep confidential or return any information which (a) is required
to be disclosed by Law, pursuant to an order or request of a judicial  authority
or Governmental Entity having competent  jurisdiction,  or pursuant to the rules
and  regulations  of any national  stock  exchange  applicable to the disclosing
party  and  its  Affiliates   (provided  the  party  seeking  to  disclose  such
information  provides the other party with reasonable prior notice thereof),  or
(b) which can be shown to have been generally  available to the public otherwise
than as a result of a breach of this Section 6.7.

      6.8. No  Solicitation.  Except for the  transactions  contemplated by this
Agreement, from and after the date of this Agreement,  neither Parent nor Seller
shall, nor shall they authorize or permit any officer, director, or employee of,
or any investment banker, attorney, accountant, or other representative retained
by,  Parent,  Seller,  or any Subsidiary  to,  directly or indirectly,  solicit,
initiate,  encourage or entertain  (including by way of furnishing  information)
discussions,  inquiries, offers, or proposals, or participate in any discussions
or negotiations for the purpose or with the intention of leading to any proposal
or offer from any Person which  constitutes  or concerns,  or may  reasonably be
expected to lead to, any  proposal  for a merger or other  business  combination
involving  Seller or any  Subsidiary  or any proposal or offer to acquire any of
the  outstanding  shares of  capital  stock of Seller or any  Subsidiary  or any
material portion of the Purchased Assets.

      6.9.  Publicity.  Prior to the Closing,  no party to this  Agreement  will
issue or cause the publication of any press release or other public announcement
with respect to this Agreement or the transactions  contemplated  hereby without
the prior consent of all other parties,  which consent will not be  unreasonably
withheld;  provided,  however,  that nothing herein will prohibit any party from
issuing or causing  publication of any such press release or public announcement
to the extent  that such party  determines  such action to be required by Law or
the rules of any national stock exchange applicable to it or its Affiliates,  in
which event the party making such  determination  will allow all other parties a
period of time that is  reasonable  under the  circumstances  to comment on such
release or announcement in advance of its issuance.

      6.10.  Satisfaction  of  Conditions.  Without  limiting the  generality or
effect of any  provision  of  Article  VII,  prior to the  Closing,  each of the
parties will use commercially  reasonable efforts with due diligence and in good
faith to satisfy promptly all conditions required hereby to be satisfied by such
party in order to expedite the  consummation  of the  transactions  contemplated
hereby.  Without  limiting the generality of the foregoing,  if any Governmental
Entity having  jurisdiction  over any party issues or otherwise  promulgates any
injunction,  decree,  or similar order prior to the Closing which  prohibits the
consummation of



                                     40











the  transactions  contemplated  hereby,  the parties will use their  respective
commercially  reasonable efforts to have such injunction  dissolved or otherwise
eliminated as promptly as possible and, prior to or after the Closing, to pursue
the underlying litigation diligently and in good faith.

      6.11.  Repayment  of  Indebtedness;  Release  of Liens.  Parent and Seller
shall,  at or  immediately  prior to the  Closing,  cause  each of the  Acquired
Subsidiaries to pay all amounts owing in respect of  indebtedness  including (A)
all  obligations  of any Acquired  Subsidiary for borrowed money or evidenced by
bonds,  debentures,  notes, letters of credit, or similar  instruments,  (B) all
obligations  as lessee under  capital  leases,  (C) all  obligations  to pay the
deferred  purchase  price of property or  securities,  except  accounts  payable
arising in the ordinary course of business  consistent  with past practice,  and
(D) all similar  obligations to others guaranteed by any Acquired  Subsidiary or
secured by a Lien or any of the assets of any Acquired Subsidiary.  In addition,
Parent and Seller shall, at or immediately  prior to the Closing,  cause each of
the  Acquired  Subsidiaries  to obtain  the  release  of any Liens  (other  than
Permitted Liens) on the properties and assets of the Acquired Subsidiaries.

      6.12. RII Distribution of Assets and Liabilities. Notwithstanding anything
to the contrary  contained in this Agreement,  it is  contemplated  that Parent,
Seller and RII will,  prior to Closing,  take or cause to be taken the following
actions:

                        (i)RII will  distribute to Seller,  by dividend,  all of
      its assets and liabilities  (including,  without  limitation,  the license
      from RIMC); and

                       (ii)RII will be dissolved or liquidated.

      6.13. Termination of Intercompany Agreements. Except as otherwise provided
on Schedule 6.13,  all Contracts  entered into prior to the Closing Date between
or among  Parent,  Seller,  or RII or any  Affiliate of Parent,  Seller,  or RII
(other  than  any  Acquired  Subsidiary),  on the one  hand,  and  any  Acquired
Subsidiary,  on the other hand,  shall be  terminated at or prior to the Closing
(without penalty, prejudice or cost to Purchaser).

      6.14.  Cancellation  of Intercompany  Notes.  Parent and Seller shall take
such action as is necessary to cancel the  intercompany  notes of Rheox Ltd. and
Rheox GmbH listed on Schedule 6.14 hereto (the "Intercompany Notes") in exchange
for the issuance to Seller or RII of additional shares of capital stock of Rheox
Ltd. or Rheox Gmbh, as the case may be. Upon issuance of such additional  shares
of capital stock,  Seller shall promptly provide to Purchaser  amended Schedules
5.1.2.B and 1.1.11.A to reflect the foregoing transactions.






                                     41

      9.1.    Employee Benefits Plans and Practices.

              (a)    Employment.




                                     46











              Bargaining Unit  Employees.  Purchaser shall assume on the Closing
Date the collective  bargaining  agreements set forth on Schedule  5.1.18(a) and
shall  employ  each of the  United  States  bargaining  unit  Employees  who are
employed  on the  Closing  Date and are  covered by such  agreements;  provided,
however,  except to the extent of the amount  accrued on the  Closing  Statement
prepared in accordance with Section 3.2(c),  Seller shall remain responsible for
employee  welfare  benefits  for  U.S.  bargaining  unit  Employees  who are not
actively  at work on the  Closing  Date until the date such  employees  commence
active work with Purchaser or any of its Affiliates.

              Non-Bargaining  Unit  Employees.  All of the  non-bargaining  unit
Employees  (other than the  individuals  set forth on  Schedule  9.1(a)) who are
actively  working  on the  Closing  Date shall be  offered  employment  with the
Purchaser as of the Closing Date,  and such  Employees  who continue  employment
after the Closing Date shall be hereafter referred to as "Continued  Employees."
Each such offer of employment to such  non-bargaining unit Employees shall be at
the same salary and cash bonus  opportunity  (in the  aggregate)  or hourly wage
rate and  position in effect on the  Closing  Date.  Purchaser  shall also offer
employment  to  each  non-bargaining  unit  Employee  who  is  employed  but  is
temporarily  absent from active  employment on the Closing Date upon termination
of such temporary  absence  within 6 months  following the Closing Date provided
such Employee is able to perform the  essential  functions of the position he or
she  previously  held with the Seller prior to such  absence,  and any such U.S.
Employee shall be treated as a Continued Employee from and after his or her date
of employment with Purchaser.

              (b)    [Intentionally Omitted]

              (c)  Purchaser  Benefit  Plans.  Effective  immediately  as of the
Closing  Date,  except as otherwise  specifically  provided in this Section 9.1,
Purchaser  will provide or cause any of its  subsidiaries  to provide  Continued
Employees at such time with  coverage  initially  under the  applicable  benefit
plans described in Schedule 9.1(c)  ("Purchaser  Benefit Plans").  Purchaser has
provided  or will  provide  prior to Closing (to the extent  available  prior to
Closing) a copy (or, if a copy is not available,  a written description) of each
Purchaser Benefit Plan to Seller.

              (d) Past Service  Credit and  Continued  Credit.  Purchaser  shall
amend the Purchaser  Benefit  Plans to the extent  necessary or  appropriate  to
credit Continued  Employees under such plans for their period of employment with
the Seller or any of its  Subsidiaries  or  Affiliates  solely for  purposes  of
eligibility, vesting and eligibility for levels of benefits under such plans and
will waive  pre-existing  conditions  to the same extent  waived by Seller under
similar  Employee  Plans.  Seller  shall,  subject  to the  Closing,  fully vest
Continued  Employees in their  accrued  benefits  under the Seller's  retirement
plans and  continue  to  credit  those  Continued  Employees  who are  presently
eligible for early retirement with their service



                                     47











with  Purchaser  and its  subsidiaries  or  affiliates  solely for  purposes  of
eligibility  for  early  or  normal  retirement   benefits  under  the  Seller's
retirement plans.

              (e) Unpaid Wages. On the Closing Date,  Purchaser agrees that with
respect to current  bargaining  unit Employees on the Closing Date and Continued
Employees it shall be  responsible  and liable for (and  Purchaser  shall pay or
cause the  relevant  subsidiary  to pay in the  ordinary  course)  solely to the
extent  accrued on the  Closing  Statement  all  accrued  and  unpaid  wages for
services rendered, vacation, and cash bonuses. Seller shall pay all other salary
continuation payments (including,  but not limited to, disability or paid leaves
of absence) to Employees with respect to the period prior to their  commencement
of active work with Purchaser or any of its Affiliates.

              (f) Union  Benefit  Plans.  In the case of  contracts  relating to
employee benefits coverage for bargaining unit Employees,  Purchaser may seek to
adopt or cause a subsidiary  to adopt  substantially  identical  contracts  with
respect to the period  following the Closing Date,  and Seller shall  reasonably
cooperate with and assist Purchaser with respect to such contracts.

              (g) Medical and Death Benefits.  Schedule 9.1.(g) lists the former
bargaining  unit  Employees  or  their  surviving  spouses  who are  covered  by
post-retirement medical and life insurance benefits.  Schedule 9.1.(g) lists the
type of  post-retirement  medical and life  insurance  plan  applicable  to such
former bargaining unit Employees  (including the type of coverage (i.e.,  single
or family).

                     (i) Seller shall provide  post-retirement  medical benefits
      in  accordance  with  the  current  terms  of the  Employee  Plans  to any
      Continued  Employee who retires from Purchaser or its Affiliates  prior to
      1999 and was eligible for such benefits if they had retired on the Closing
      Date.

                     (ii) Medical Claims. Seller shall continue to administer in
      accordance  with past practices all claims for medical and dental services
      rendered before the Closing Date with respect to Employees.

              (h)  401(k)   Plan.   After  the  Seller   receives  a   favorable
determination  by the Internal  Revenue Service on the  qualification  of the NL
Industries  Retirement  Savings Plan under Section 401 of the Code, Seller shall
promptly cause such plan to transfer to Purchaser's  401(k) plan which Purchaser
shall cause to accept such transfer, in a trust-to-trust  transfer in compliance
with  applicable  Laws,  an amount in cash equal to the  vested  and  non-vested
account  balances  as of the  last  day of a  calendar  month  of all  Continued
Employees and all bargaining unit Employees,  together with earnings  thereon at
the applicable rate available under such plan to the actual date of transfer.
Seller and Purchaser shall each provide the



                                     48











other with  reasonable  assurances  that its 401(k) plan qualifies under Section
401 of the Code.  Purchaser  shall  cause its  401(k)  plan to comply  with Code
Section 411(d)(6) with respect to the amounts so transferred.

              (i) Amendment of Plans,  Severance Pay.  Nothing in this Agreement
shall limit,  subject to applicable  Laws,  Purchaser's  right,  at any time, to
dismiss any or all Continued Employees or Subsidiary Employees at any time, with
or without  cause,  and to change the terms and  conditions of their  employment
(including  compensation and employee benefits provided to them);  provided that
any such  Continued  Employee or  Subsidiary  Employee  dismissed  without cause
within 12 months  following  the Closing  Date shall be entitled to receive from
Purchaser  severance pay, in accordance with the severance  policy  disclosed on
Schedule  5.1.18 (a  complete  and  correct  copy of each such  policy  has been
provided to Purchaser).  Nothing in this Agreement  shall preclude  amendment or
termination of any of Purchaser Benefit Plans or the Employee Plans, as to which
Purchaser has no present  intention to amend or  terminate,  at any time without
notice to Employees or any other affected  individual.  Purchaser has no present
intention to materially  reduce the  compensation  of any Continued  Employee or
Subsidiary Employee after Closing.

              (j)  Cooperation.  Purchaser,  Parent,  Acquired  Subsidiaries and
Seller agree to cooperate in  collecting  and  providing  information  as may be
required by any of them in order to discharge its respective  obligations  under
this Section  9.1.  Purchaser,  Parent,  Acquired  Subsidiaries  and Seller each
agrees to promptly make all payments and perform all obligations with respect to
which they have retained liability under Section 9.1.

              (k)  Employee  Notices  and   Certificates.   Purchaser  shall  be
responsible for issuing certificates or notices in lieu of certificates intended
to comply with the Health  Insurance  Portability  and  Accountability  Act with
respect  to  Continued  Employees,  and Seller and  Purchaser  shall  reasonably
cooperate with each other to ensure that such certificates or notices are timely
provided to such Employees.  Purchaser  agrees not to take any action or omit to
take any action in connection  with the hiring process that would subject Seller
to any  responsibility or liability under the Workers  Adjustment and Retraining
Notification Act with respect to Continued Employees.

              (l)  Withholding.  Seller  agrees to  transfer  to  Purchaser  any
records  (including,  but not limited  to,  Forms W-4 and  Employee  Withholding
Allowance  Certificates)  relating  to  withholding  and  payment  of income and
employment  taxes  (federal,  state,  and local) and FICA taxes with  respect to
wages paid by Seller during the current  calendar  year to Continued  Employees.
Purchaser  agrees,  to the extent  permitted by applicable  Law, to provide such
employees with Forms W-2, Wage and Tax Statements for the current  calendar year
setting forth the wages and taxes  withheld  with respect to such  employees for
the current calendar year by Seller and Purchaser,  as predecessor and successor
employers, respectively.



                                     49











Seller and Purchaser also agree to comply with the filing requirements set forth
in Revenue Procedure 96-60 to implement this Section.

              (m) Insurance.  Seller shall maintain  through the last day of the
calendar month in which the Closing Date occurs the insurance  policies (and not
administration  service obligation contracts) in effect immediately prior to the
Closing Date under the applicable Employee Plan.

              (n) No  Third  Party  Beneficiaries.  Nothing  contained  in  this
Section 9.1 shall be  construed to grant to any  Continued  Employees a right to
employment  by  Purchaser  for any  particular  length  of time or to  otherwise
provide to any such Continued Employee any rights or remedies under or by reason
of this Agreement.

              (o) U.K. Pension  Schedule.  The parties will take such actions as
may be  required  to be taken  pursuant to the U.K.  pension  schedule  attached
hereto as Exhibit  F,  which  schedule  is deemed to be  incorporated  into this
Agreement for all purposes (including for the purposes of Article X hereof).

      9.2.  Maintenance  of Books and Records.  Seller shall and shall cause RII
to, and Purchaser  shall and shall cause each Acquired  Subsidiary to,  preserve
until the eighth  anniversary of the Closing Date all records possessed or to be
possessed  by such party  relating  to any of the assets or  liabilities  of the
Business, or the operation of the Business, prior to the Closing Date. After the
Closing Date, where there is a legitimate purpose,  such party shall provide the
other parties with access,  upon prior reasonable written request specifying the
need therefor,  during regular business hours, to (a) the officers and employees
of such party and (b) the books of account and  records of such  party,  but, in
each case, only to the extent relating to the assets, liabilities or business of
the  Business  prior to the  Closing  Date,  and the  other  parties  and  their
representatives  shall have the right to make copies of such books and  records;
provided,  however,  that the foregoing right of access shall not be exercisable
in such a manner as to interfere  unreasonably  with the normal  operations  and
business  of such  party;  and  provided,  further  that,  as to so much of such
information as constitutes trade secrets or confidential business information of
such  party,   the   requesting   party  and  its   officers,   directors,   and
representatives will use due care to not disclose such information except to the
extent such information (a) is required to be disclosed by Law or pursuant to an
order or request of a judicial authority or Governmental Entity having competent
jurisdiction  (provided the party seeking to disclose such information  provides
the other party or parties with  reasonable  prior notice  thereof) or (b) which
can be shown to have been generally  available to the public otherwise than as a
result of a breach  of this  Section  9.2.  Such  records  may  nevertheless  be
destroyed by a party if such party sends to the other parties  written notice of
its intent to destroy records, specifying with particularity the contents of the
records to be destroyed.  Such records may then be destroyed  after the 30th day
after such notice is given unless another party



                                     50











objects  to the  destruction,  in which case the party  seeking  to destroy  the
records shall either agree to retain such records or deliver such records to the
objecting party.

      9.3. Payments Received.  After the Closing, Seller will and will cause RII
to, and  Purchaser  will and will cause each  Acquired  Subsidiary  to, hold and
promptly  transfer  and  deliver  to the  other,  from  time to time as and when
received by them, any cash,  checks with appropriate  endorsements  (using their
best efforts not to convert such checks into cash),  or other property that they
may receive on or after the Closing which  properly  belongs to the other party,
including  without  limitation any insurance  proceeds,  and will account to the
other for all such receipts.

      From and after the Closing,  Purchaser  shall have the right and authority
to  endorse  without  recourse  the name of  Seller or RII on any check or other
evidence of indebtedness received by the Purchaser on account of the Business or
the Purchased Assets transferred to the Purchaser hereunder.

      9.4. Use of Name. From and after the Closing Date, Parent and Seller will,
and will cause RII and each of its  Affiliates  to, sign such  consents and take
such  other  action as  Purchaser  shall  reasonably  request in order to permit
Purchaser to use the name "Rheox,"  "Bentone,"  and variants  thereof.  From and
after the  Closing  Date,  Seller  will not  itself,  and will cause RII and its
Affiliates not to, use the name "Rheox," "Bentone," or any names similar thereto
or variants  thereof and shall use commercially  reasonable  efforts to promptly
amend  and  cause  RII  and  each  Affiliate  to  amend  its  charter  or  other
organizational documents to remove such reference.

      9.5. UCC Matters.  From and after the Closing  Date,  Seller will and will
cause RII to promptly  refer all  inquiries  with  respect to  ownership  of the
Purchased Assets or the Business to Purchaser. In addition, Seller will and will
cause RII to execute such documents and financing and termination  statements as
Purchaser may reasonably  request from time to time to evidence  transfer of the
Purchased Assets to Purchaser and the release of any Liens therefrom.

      9.6.  Covenant Not to Compete.  Until the fifth anniversary of the Closing
Date  (such  period of time  being  referred  to  herein as the  "Noncompetition
Term"),  each of Parent and Seller severally agrees to refrain from, anywhere in
the world,  directly or indirectly  through any  controlled  Affiliate  (whether
individually  or  as a  principal,  officer,  director,  employee,  shareholder,
investor, consultant,  advisor, partner, joint venturer, agent, equity owner, or
in any other capacity whatsoever):

              (a) engaging or  participating in any activity with respect to the
      development, manufacturing, marketing, and sale of rheological products or
      products



                                     51











      using the same or similar  chemistry  ("Products")  that  compete with the
      Business as presently  conducted;  provided,  however,  that the foregoing
      shall  not be  construed  to  preclude  Parent,  Seller,  or any of  their
      respective Affiliates from (i) making any investments in the securities of
      any person,  whether or not engaged in  competition  with the  Business as
      presently  conducted,  to the extent  that such  securities  are  actively
      traded on a national securities exchange or in the over-the-counter market
      in  the  United  States  or  any  foreign  securities  exchange  and  such
      investment  does not exceed  five  percent  of the issued and  outstanding
      shares of such Person or give Parent,  Seller,  or any of their respective
      Affiliates the right or power to control or participate directly in making
      the policy decisions of such Person or (ii) acquiring all or substantially
      all of the assets or voting stock of any person which is engaged primarily
      in a business not in competition with the Business as presently  conducted
      but which has a direct or indirect division, subsidiary, or other business
      unit which  competes with the Business (the  "Competing  Business  Unit"),
      provided  that  Parent,   Seller,  or  such  Affiliates  shall  use  their
      respective commercially reasonable efforts to sell or otherwise dispose of
      such  Competing  Business  promptly  following  the  consummation  of such
      acquisition; or

              (b) causing or  attempting  to cause (A) any  customer to whom the
      Business  supplies  Products to terminate  any  purchase or other  similar
      Contract,  or  relationship  with the  Business  after the  Closing  or to
      replace the Business as a supplier of Products,  in whole or in part, with
      any other Person, or (B) any supplier from whom the Business purchases raw
      materials  and other  products to  terminate  any supply or other  similar
      Contract or relationship with the Business; or

              (c)   except  as   otherwise   contemplated   by  this   Agreement
      encouraging,  soliciting, or inducing any manager, officer, supervisor, or
      other  employee  of the  Business  to  terminate  his  or  her  employment
      relationship  with the Business or to become  employed by any Person other
      than the Business.

Each of Parent and Seller severally acknowledges that the geographic boundaries,
scope of prohibited  activities  and the  Noncompetition  Term contained in this
Section  9.6 are  reasonable  and no  broader  than  necessary  to  protect  the
investment by Purchaser in the Purchased Assets being acquired  pursuant to this
Agreement and Purchaser's and its Affiliates  ongoing  interests in the Business
and do not and will not  impose  any  unreasonable  burden  upon any of  Parent,
Seller,  or their  respective  Affiliates.  Each of Parent and Seller  severally
agree  that (i) any  breach  by it of any of the  provisions  contained  in this
Section 9.6 would  cause  irreparable  damage to  Purchaser  for which  monetary
damages and other  remedies at law may not be adequate,  and (ii) Purchaser will
be entitled to seek a restraining order, an injunction, specific performance, or
other form of  equitable  or  extraordinary  relief from any court of  competent
jurisdiction  to restrain any  threatened or further  breach of this Section 9.6
above or to  require  any of Parent or Seller to perform  his or its  respective
obligations under this Section 9.6,



                                     52











which right to  equitable or  extraordinary  relief will not be exclusive of but
will be in addition to all other  remedies  to which  Purchaser  may be entitled
under this  Agreement,  at law,  or in equity  (including,  the right to recover
monetary damages). As consideration for the agreements set forth in this Section
9.6, Purchaser agrees to pay to Parent at the Closing $20,000,000 by delivery of
cash payable by wire transfer of immediately available funds.

              (b)  Subject  to  Section  10.1 and 10.2,  H&C,  H&C  America  and

partners, employees, agents, and representatives from



                                     59











and  against  any  and all  Indemnifiable  Losses  to the  extent  relating  to,
resulting from, or arising out of:

                        (i)any breach of  representation or warranty of H&C, H&C
      America or Purchaser under the terms of this Agreement and any certificate
      delivered pursuant hereto;

                       (ii)any  breach or  nonfulfillment  of any  agreement  or
      covenant  of H&C,  H&C  America  or  Purchaser  under  the  terms  of this
      Agreement and any certificate delivered pursuant hereto; and

                      (iii)any Assumed Liabilities.

      10.4.   Defense of Claims.

              (a) If any Indemnitee receives notice of assertion or commencement
of any Third  Party  Claim  against  such  Indemnitee  with  respect to which an
Indemnifying Party is obligated to provide indemnification under this Agreement,
the  Indemnitee  will give such  Indemnifying  Party  reasonably  prompt written
notice  thereof,  but in any event not later than 10 calendar days after receipt
of such notice of such Third Party  Claim.  Such notice will  describe the Third
Party Claim in reasonable  detail,  will include copies of all material  written
evidence  thereof,  and  will  indicate  the  estimated  amount,  if  reasonably
practicable,  of the Indemnifiable Loss that has been or may be sustained by the
Indemnitee. The Indemnifying Party will have the right to participate in, or, by
giving written  notice to the  Indemnitee,  to assume,  the defense of any Third
Party Claim at such  Indemnifying  Party's own expense and by such  Indemnifying
Party's  own  counsel  (reasonably  satisfactory  to the  Indemnitee),  and  the
Indemnitee will cooperate in good faith in such defense.

              (b) If,  within 10 calendar  days after  giving  notice of a Third
Party Claim to an Indemnifying Party pursuant to Section 10.4(a),  an Indemnitee
receives written notice from the Indemnifying  Party that the Indemnifying Party
has  elected to assume the  defense of such Third Party Claim as provided in the
last sentence of Section 10.4(a),  the Indemnifying Party will not be liable for
any legal expenses  subsequently  incurred by the Indemnitee in connection  with
the defense thereof; provided,  however, that if the Indemnifying Party fails to
take  reasonable  steps  necessary to defend  diligently  such Third Party Claim
within 10 calendar days after receiving  written notice from the Indemnitee that
the Indemnitee  believes the Indemnifying Party has failed to take such steps or
if the  Indemnifying  Party has not undertaken fully to indemnify the Indemnitee
in respect of all  Indemnifiable  Losses relating to the matter,  the Indemnitee
may assume its own defense,  and the  Indemnifying  Party will be liable for all
reasonable costs or expenses paid or incurred in connection  therewith.  Without
the prior written consent of the  Indemnitee,  the  Indemnifying  Party will not
enter into any



                                     60











settlement  of any Third Party Claim which would lead to liability or create any
obligation  on the  part of the  Indemnitee  for  which  the  Indemnitee  is not
entitled to indemnification hereunder.

              (c) A failure to give timely  notice or to include  any  specified
information  in any notice as provided in Sections  10.4(a) or 10.4(b)  will not
affect the rights or obligations of any party  hereunder  except and only to the
extent  that,  as a result of such  failure,  any party  which was  entitled  to
receive such notice was actually prejudiced as a result of such failure.

              (d) The Indemnifying  Party will have a period of 30 calendar days
within which to respond in writing to any claim by an  Indemnitee  on account of
an Indemnifiable  Loss which does not result from a Third Party Claim (a "Direct
Claim").  If the Indemnifying  Party does not so respond within such 30 calendar
day period,  the Indemnifying  Party will be deemed to have rejected such claim,
in which event the  Indemnitee  will be free to pursue  such  remedies as may be
available to the  Indemnitee on the terms and subject to the  provisions of this
Article X.

              (e)  If  the  amount  of  any  Indemnifiable  Loss,  at  any  time
subsequent  to the making of an  Indemnity  Payment,  is  reduced  by  recovery,
settlement,  or  otherwise  under or  pursuant  to any  insurance  coverage,  or
pursuant to any claim, recovery,  settlement, or payment by or against any other
Person,  the amount of such  reduction,  less any costs,  expenses,  premiums or
taxes incurred in connection therewith will promptly be repaid by the Indemnitee
to the Indemnifying  Party.  Upon making any Indemnity  Payment the Indemnifying
Party will, to the extent of such Indemnity Payment, be subrogated to all rights
of the Indemnitee  against any Person that is not an Affiliate of the Indemnitee
in respect of the  Indemnifiable  Loss to which the Indemnity  Payment  related;
provided,  however,  that (i) the Indemnifying Party shall then be in compliance
with its obligations under this Agreement in respect of such  Indemnifiable Loss
and (ii) until the Indemnitee  recovers fully payment of its Indemnifiable Loss,
any and all claims of the Indemnifying  Party against any such Person on account
of said  Indemnity  Payment  will be  subrogated  and  subordinated  in right of
payment to the  Indemnitee's  rights against such Person.  Without  limiting the
generality or effect of any other  provision  hereof,  each such  Indemnitee and
Indemnifying  Party will duly execute upon  request all  instruments  reasonably
necessary  to  evidence  and  perfect  the   above-described   subrogation   and
subordination rights.

      10.5.   Conduct of Remedial Actions.

              (a) The  obligations  of Seller  and Parent to  indemnify  the H&C
Indemnified  Parties for any Remedial Action pursuant to Sections 10.3(a)(i) (as
it relates to a breach of any  representation  or warranty  contained in Section
5.1.22) or 10.3(a)(iv) hereof shall be subject to the following:



                                     61











                        (i)any  Remedial  Action  (1)  must  be  required  by  a
      Governmental Authority or Environmental Laws or be necessary to achieve or
      maintain  compliance with Environmental  Laws; (2) shall be performed in a
      commercially reasonable,  cost-effective manner; and (3) shall use cleanup
      criteria  no  more  stringent  than  (A) if  specific  applicable  cleanup
      criteria are specified by  applicable  Environmental  Laws,  that specific
      cleanup criteria, or (B) otherwise, cleanup criteria that are commercially
      reasonable and  appropriate to comply with applicable  Environmental  Laws
      (in all cases where permitted and appropriate  such cleanup criteria shall
      be that applicable to real property that is used for industrial purposes);

                       (ii)if a need for Remedial Action arises, Purchaser shall
      provide Seller notice thereof as soon as reasonably  practicable under the
      circumstances;  provided,  however that the failure to give such notice to
      Seller should not affect the obligations  hereunder unless Seller has been
      materially prejudiced as a result thereof; and

                      (iii)prior  to the  commencement  of any Remedial  Action,
      Purchaser  shall provide  Seller with a plan as to its intended  course of
      action. Seller shall have the right to review such plan with Purchaser, to
      consult with Purchaser with respect to the finalization and implementation
      of such plan and, if Seller does not concur in  Purchaser's  proposed plan
      of action,  to  provide  alternative  proposals  for the  undertaking  and
      completion of such Remedial  Action.  Notwithstanding  the  foregoing,  if
      Purchaser  and  Seller,  after due  consultation,  cannot  agree as to the
      method of proceeding,  or the reasonable costs and expenses to be incurred
      in  connection  therewith,  Purchaser  shall  have the right to assume the
      obligation  to  complete  such  Remedial  Action,   which  is  subject  to
      indemnification hereunder.

              (b) The party  conducting the Remedial  Action shall (i) comply in
all material respects with  Environmental  Laws, (ii) in a timely manner, but no
less often than once every three  months,  provide the other party with progress
reports with respect to the Remedial  Action,  and (iii) provide the other party
with all substantive  correspondence to or from any Governmental Authority,  all
reports, all sampling results, and all other relevant and significant  documents
relating to the Remedial Action and endeavor to provide the other party with the
opportunity to participate in any material  discussions  with such  Governmental
Authority.

              (c) Any party incurring costs hereunder,  a portion of which is to
be  paid by  another  party  hereto  (for  purposes  of this  Section  10.5,  an
"Obligated  Party") pursuant to Article X, shall deliver to the Obligated Party,
on a quarterly  basis,  invoices for any Remedial  Action  effected  during such
quarterly period, along with appropriate back-up documentation, setting forth in
reasonable detail the work done during such period and a detailed break-down



                                     62











of the fees and expenses  incurred in connection  therewith and included in such
invoice.  The  Obligated  Party  shall pay such  invoices  within 30 days  after
receipt thereof,  except with respect to any portion thereof which they claim by
written notice to the other party, delivered within 20 days after receipt of any
such invoice, does not conform to the terms of this indemnification plus, in the
event payment is not made within such 30 day period as required hereby, interest
thereon  at a  rate  of  seven  percent  (7%)  per  annum,  accruing  daily  and
compounding annually.

              (d) With  respect to any invoices  disputed by an Obligated  Party
hereunder,  the parties shall use  reasonable  efforts to resolve such matter or
matters on or before the due date of the relevant invoice; if the parties cannot
resolve any such dispute,  said matters  shall be referred for  resolution to an
independent  engineering  consulting  firm mutually  agreed upon by the parties,
whose determination with respect to any such disputed matters shall be final and
binding upon Parent, Seller, H&C and Purchaser.

      10.6.  Adjustment to Purchase Price. Any Indemnity Payment hereunder shall
be treated as an adjustment to the Purchase Price.

              (c) By H&C, H&C America, and Purchaser, on the one hand, or Parent
      and Seller,  on the other hand,  if there shall have been entered a final,
      nonappealable  order or injunction of any Governmental  Entity restraining
      or prohibiting the consummation of the transactions contemplated hereby or
      any material part thereof;

              (d) By H&C, H&C America, and Purchaser by giving written notice to

                                     63











      previous  15  business  days given  Buyer any notice  pursuant  to Section
      6.3(b)  above and (B) the  development  that is the subject of the notice,
      together with any  developments  that are or were the subject of any prior
      notice  pursuant to Section 6.3(b) (whether or not such prior notices were
      given during the previous 15 business days),  has had or could  reasonably
      be expected to have a Material Adverse Effect; or

              (e) By H&C, H&C America, and Purchaser, on the one hand, or Parent
      and Seller,  on the other hand,  if, prior to the Closing Date,  the other
      party  is in  breach  in  any  material  respect  of  any  representation,
      warranty,   covenant,   or  agreement   herein  contained  (other  than  a
      representation  and warranty which is subject to the notice  provisions of
      Section 6.3(b) and the  termination  provisions of Section  11.1(d) above)
      and such breach shall not be cured  within 5 business  days of the date of
      notice of breach served by the party claiming such breach.

      11.2.  Effect of  Termination.  If this  Agreement  is validly  terminated

and 12.17, shall become null and void and of no further force and effect and all
obligations  of the  parties  hereto  shall  terminate  and  there  shall  be no

any of its  representations,  warranties,  covenants,  or agreements  under this
Agreement prior to its termination.


                    ARTICLE XII.  MISCELLANEOUS PROVISIONS

      12.1. Specific Performance.  The parties recognize that if any other party
refuses to perform under the  provisions  of this  Agreement,  monetary  damages
alone will not be adequate to compensate such party for its injuries. Each party
shall  therefore  be  entitled,  in addition to any other  remedies  that may be
available, to obtain specific performance of the terms of this Agreement. If any
action is brought to obtain specific performance of the terms of this Agreement,
the parties  against  whom such action is brought  shall waive the defense  that
there is an adequate  remedy at Law. In the event of a default  which results in
the filing of a lawsuit for damages,  specific  performance,  or other remedies,
the prevailing party shall be entitled to  reimbursement  by the  non-prevailing
party of reasonable legal fees and expenses incurred by them.

      12.2. Notices. All notices and other communications  required or permitted
hereunder will be in writing and, unless  otherwise  provided in this Agreement,
will be  deemed  to have  been  duly  given  when  delivered  in  person or when
dispatched  by  electronic  facsimile  transfer or one business day after having
been dispatched by an internationally recognized

herein.

      12.4.  Successors  and Assigns.  This  Agreement  will be binding upon and
inure to the benefit of the parties hereto and their  respective  successors and
permitted assigns,  but will not be assignable or delegable by any party without
the prior  written  consent of the other party  which shall not be  unreasonably
withheld;  provided,  however, that (a) nothing in this Agreement is intended to
limit  Purchaser's  ability to sell or to transfer  any or all of the  Purchased
Assets  following  the Closing  Date,  (b) prior to the Closing,  upon notice to
Seller,  Purchaser may assign or delegate to any direct or indirect wholly owned
subsidiary of H&C America, H&C, or Purchaser the right to acquire part or all of

assignment.  Seller agrees to execute  acknowledgments of such assignment(s) and
collateral  assignments  reflecting all of the conditions of such  assignment(s)
and  collateral  assignments  in such forms as H&C, H&C America and Purchaser or
H&C, H&C America's or  Purchaser's  lender(s)  may from time to time  reasonably
request.  In the event of such a proposed  assignment  by H&C,  H&C  America and
Purchaser, the provisions of this Agreement shall inure to the benefit of and be
binding upon H&C's, H&C America's and Purchaser's assigns.

      12.5.  Waiver.  Purchaser  (on behalf of itself,  H&C and H&C America) and
Seller  (on behalf of itself,  Parent,  and RII) by written  notice to the other

modification  of  performance  with  respect  to its (or any of its  Affiliates)
representations,  warranties,  conditions,  or  covenants  hereunder.  Except as
provided in the immediately preceding sentence, no action taken pursuant to this
Agreement  will be  deemed  to  constitute  a  waiver  of  compliance  with  any
representations,   warranties,   conditions,  or  covenants  contained  in  this
Agreement  and will not operate or be  construed  as a waiver of any  subsequent
breach, whether of a similar or dissimilar nature.

      12.6.  Entire  Agreement.  This  Agreement  (including  the  Exhibits  and
Schedules  hereto and any other  documents and  instruments  delivered  pursuant
hereto)  supersedes any other agreement,  whether written or oral, that may have
been made or entered into by any party or any of their respective Affiliates (or
by any director,  officer,  or  representative  thereof) relating to the matters
contemplated  hereby.  This Agreement  (together with the Exhibits and Schedules
hereto  and any other  documents  and  instruments  delivered  pursuant  hereto)

Agreement signed by the parties hereto.

      12.8.  Rights of the Parties.  Except as provided in Articles II, IX and X
or in Section 12.4,  nothing  expressed or implied in this Agreement is intended
or will be  construed to confer upon or give any person or entity other than the
parties hereto and their  respective  Affiliates any rights or remedies under or
by reason of this Agreement or any transaction contemplated hereby.

severally  indemnify and hold harmless Parent and Seller,  and Seller and Parent
agree to jointly and severally  indemnify and hold harmless H&C, H&C America and
Purchaser,  from and against any  liability,  claim,  loss,  damage,  or expense

respectively, relating to any fees or commissions owed or allegedly



                                     67

      12.11.  Governing Law. This Agreement  shall be governed by, and construed

laws.

      12.12.  Severability.  The  parties  agree that if one or more  provisions
contained in this  Agreement  shall be deemed or held to be invalid,  illegal or
unenforceable  in any respect under any applicable  Law, this Agreement shall be
construed with the invalid, illegal, or unenforceable provision deleted, and the
validity,  legality and  enforceability  of the remaining  provisions  contained
herein shall not be affected or impaired thereby.

      12.13. Execution in Counterparts. This Agreement may be executed in two or
more  counterparts,  each of which will be deemed an original,  but all of which
together will constitute one and the same agreement.

      12.14.  Titles and  Headings.  Titles and headings to sections  herein are
inserted for convenience of reference only, and are not intended to be a part of
or to affect the meaning or interpretation of this Agreement.

      12.15.  Passage of Title and Risk of Loss.  Legal title,  equitable title,
and risk of loss with respect to the Purchased Assets will not pass to Purchaser
(or  the  H&C  Assignees,   as  applicable)  until  such  Purchased  Assets  are
transferred at the Closing, which transfer, once it has occurred, will be deemed
effective for tax, accounting,  and other computational  purposes as of the time
