                      NL INDUSTRIES, INC. AND SUBSIDIARIES

                   NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

Note 1 -  Organization and basis of presentation:

     At June 30, 2004,  NL  Industries,  Inc.  (NYSE:  NL) conducts its titanium
dioxide pigments ("TiO2") operations through its 50.5% owned subsidiary,  Kronos
Worldwide,  Inc. (NYSE:  KRO) ("Kronos").  At June 30, 2004,  Valhi,  Inc. and a
wholly-owned  subsidiary  of Valhi held  approximately  83% of NL's  outstanding
common stock, and Contran  Corporation and its subsidiaries  held  approximately
90% of  Valhi's  outstanding  common  stock.  At  June  30,  2004,  Valhi  and a
wholly-owned  subsidiary  of Valhi  also  held an  additional  43.6% of  Kronos'
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 Harold C. Simmons,  of which Mr. Simmons is sole trustee, or is
held by Mr. Simmons or persons or other  entities  related to Mr.  Simmons.  Mr.
Simmons,  the Chairman of the Board of Valhi,  Contran and the  Company,  may be
deemed to control each of such companies.

     The  consolidated  balance  sheet  of NL at  December  31,  2003  has  been
condensed from the Company's audited  consolidated  financial statements at that
date.  The  consolidated  balance sheet at June 30, 2004,  and the  consolidated
statements of income,  comprehensive income, stockholders' equity and cash flows
for the interim  periods ended June 30, 2003 and 2004, have been prepared by the
Company,  without audit,  in accordance  with  accounting  principles  generally
accepted in the United States of America ("GAAP"). In the opinion of management,
all adjustments,  consisting only of normal recurring adjustments,  necessary to
present fairly the consolidated  financial  position,  results of operations and
cash flows have been made.

     The  results of  operations  for the interim  periods  are not  necessarily
indicative  of the  operating  results for a full year or of future  operations.
Certain  information  normally  included  in  financial  statements  prepared in
accordance  with GAAP has been  condensed  or omitted,  and  certain  prior year
amounts have been reclassified to conform to the current year presentation.  The
accompanying  consolidated  financial  statements  should be read in conjunction
with the Company's  Annual  Report on Form 10-K for the year ended  December 31,
2003 (the "2003 Annual Report").

     In March  2004,  the  Company  paid its $.20 per  share  regular  quarterly
dividend  in the form of shares of Kronos  common  stock in which  approximately
345,000  shares  (approximately  .7% of Kronos'  outstanding  common stock) were
distributed to NL stockholders in the form of a pro-rata dividend. The Company's
distribution  of such shares of Kronos  common  stock is taxable to the Company,
and the Company is required to recognize a taxable gain equal to the  difference
between the fair market value of the shares of Kronos distributed on the date of
distribution and the Company's  adjusted tax basis in such shares at the date of
distribution.  Pursuant to the Company's tax sharing  agreement with Valhi,  the
Company is not  required  to pay taxes on the tax  liability  generated  for the
shares  of Kronos  distributed  to Valhi and its  wholly-owned  subsidiary.  The
Company is required  to  recognize a tax  liability  with  respect to the Kronos
shares  distributed  to NL  stockholders  other than Valhi and its  wholly-owned
subsidiary, and such tax liability was approximately $598,000 for the March 2004
distribution.  In accordance with GAAP, the net carrying value of such shares of
Kronos  distributed  ($1.1  million) and the $598,000  tax  liability  have been
recognized  as a reduction  of the  Company's  stockholders'  equity and charged
directly  to retained  earnings.  The Company  paid its next  regular  quarterly
dividend of $.20 per share in July 2004, in which  approximately  322,000 Kronos
shares (approximately .7% of Kronos' outstanding common stock) were distributed.
The effect of such  distribution  will be recognized by the Company in the third
quarter of 2004.  After  considering the July 2004  distribution,  the Company's
ownership of Kronos will be reduced to approximately  49.8% and the Company will
no longer own a majority  of Kronos'  outstanding  common  stock.  Consequently,
effective  in the third  quarter of 2004 the Company  will cease to  consolidate
Kronos' financial position, results of operations and cash flows and instead the
Company  will  commence  accounting  for its  interest  in Kronos by the  equity
method.

     The  Company   complied  with  the   consolidation   requirements  of  FASB
Interpretation ("FIN") No. 46R, "Consolidation of Variable Interest Entities, an
interpretation of ARB No. 51," as amended, as of March 31, 2004. See Note 15.

     As  disclosed  in  the  2003  Annual  Report,   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 greater than
or equal to the  market  price on the grant  date.  Prior to 2003,  the  Company
commenced  accounting for its stock options using the variable accounting method
of APBO No. 25, which  requires the  intrinsic  value of all  unexercised  stock
options  (including  stock options with an exercise  price at least equal to the
market price on the date of grant) to be accrued as an expense,  with subsequent
increases  (decreases) in the Company's market price resulting in recognition of
additional  compensation  expense (income).  Net compensation cost recognized by
the Company in accordance with APBO No. 25 was approximately $500,000 and nil in
the  second  quarter  and  first  six  months  of  2003,  respectively,  and net
compensation  cost  recognized  by the Company  was nil and $1.1  million in the
second quarter and first six months of 2004, respectively.

     The following  table presents what the Company's  consolidated  net income,
and related per share amounts,  would have been in the first quarter of 2003 and
2004 if the Company and its  subsidiaries  and  affiliates  had each  elected to
account for their respective  stock-based employee compensation related to stock
options in accordance with the fair value-based  recognition  provisions of SFAS
No. 123,  "Accounting  for  Stock-Based  Compensation,"  for all awards  granted
subsequent to January 1, 1995.

     Certain of the Company's  U.S. and non-U.S.  tax returns are being examined
and tax authorities have or may propose tax  deficiencies,  including  penalties
and interest. For example:

o    NL's and NL's  majority-owned  subsidiary's,  NL  Environmental  Management
     Services,  Inc.  ("EMS"),  1998 U.S.  federal  income tax returns are being
     examined  by  the  U.S.  tax  authorities,  and  NL and  EMS  have  granted
     extensions  of the  statute  of  limitations  for  assessments  of tax with
     respect to their 1998, 1999 and 2000 income tax returns until September 30,
     2005. During the course of the examination,  the IRS proposed a substantial
     tax deficiency, including interest, related to a restructuring transaction.
     In an effort to avoid  protracted  litigation  and  minimize the hazards of
     such  litigation,  NL applied to take part in an IRS settlement  initiative
     applicable to transactions similar to the restructuring transaction, and in
     April 2003 NL received  notification from the IRS that NL had been accepted
     into such settlement initiative.  Under the initiative,  a final settlement
     with  the IRS is to be  reached  through  expedited  negotiations  and,  if
     necessary,  through a specified  arbitration  procedure.  NL has reached an
     agreement with the IRS concerning the settlement of this matter pursuant to
     which,  among other things,  the Company  agreed to pay  approximately  $24
     million,  including  interest,  up  front  as  a  partial  payment  of  the
     settlement  amount  (which  amount  is  expected  to be paid in the next 12
     months and is classified as a current  liability at June 30, 2004),  and NL
     will be  required  to  recognize  the  remaining  settlement  amount in its
     taxable income over the next 15 years  beginning in 2004. NL has signed the
     settlement  agreement  that was  prepared by the IRS. The IRS will sign the
     settlement agreement after certain procedural matters are concluded,  which
     procedural  matters  both NL and its  outside  legal  counsel  believe  are
     perfunctory.  NL had  previously  provided  accruals to cover its estimated
     additional tax liability (and related interest)  concerning this matter. As
     a result of the settlement,  NL has decreased its previous  estimate of the
     amount of additional  income taxes and interest it will be required to pay,
     and NL recognized a $12.6 million tax benefit in the second quarter of 2004
     related to the revised estimate. In addition,  during the second quarter of
     2004,  the Company  recognized a $30.5  million tax benefit  related to the
     reversal  of a deferred  income tax asset  valuation  allowance  related to
     certain   tax   attributes   of  EMS  which  NL   believes   now  meet  the
     "more-likely-than-not"  recognition  criteria.  A majority of the  deferred
     income  tax  asset  valuation  allowance  relates  to  net  operating  loss
     carryforwards  of EMS. As a result of the settlement  agreement,  NL (which
     previously was not allowed to utilize such net operating loss carryforwards
     of EMS) will fully  utilize such  carryforwards  in its 2003 taxable  year,
     eliminating   the  need  for  a   valuation   allowance   related  to  such
     carryforwards.  The  remainder of the deferred  income tax asset  valuation
     allowance  relates to  deductible  temporary  differences  associated  with
     accrued  environmental  obligations  of EMS which NL now believes  meet the
     "more-likely-than-not"  recognition  criteria  since,  as a  result  of the
     settlement agreement,  such obligations and the related tax deductions will
     be included in NL's taxable income.
o    Kronos has received a preliminary  tax assessment  related to 1993 from the
     Belgian tax  authorities  proposing  tax  deficiencies,  including  related
     interest,  of  approximately  euro 6 million ($7 million at June 30, 2004).
     Kronos  has  filed  a  protest  to  this  assessment  and  believes  that a
     significant  portion of the  assessment is without  merit.  The Belgian tax
     authorities  have filed a lien on the fixed assets of Kronos'  Belgian TiO2
     operations  in  connection  with this  assessment.  In April  2003,  Kronos
     received a notification from the Belgian tax authorities of their intent to
     assess a tax  deficiency  related  to 1999  that,  including  interest,  is
     expected to be approximately euro 13 million ($16 million). Kronos believes
     the proposed  assessment is  substantially  without  merit,  and Kronos has
     filed a written response.
o    The  Norwegian  tax  authorities  have  notified  Kronos of their intent to
     assess tax deficiencies of  approximately  kroner 12 million ($2 million at
     June 30, 2004)  relating to the years 1998 to 2000.  Kronos has objected to
     this proposed assessment.

     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  settlement
initiatives,  court  and  tax  proceedings.  The  Company  believes  that it has
provided  adequate  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  its  consolidated  financial  position,  results  of  operations  or
liquidity.

     At December 31, 2003, Kronos had a significant amount of net operating loss
carryforwards for German corporate and trade tax purposes,  all of which have no
expiration  date. These net operating loss  carryforwards  were generated by KII
principally  during  the 1990's  when KII had a  significantly  higher  level of
outstanding indebtedness than is currently outstanding.  For financial reporting
purposes,  however, the benefit of such net operating loss carryforwards had not
previously  been  recognized  because  Kronos  did  not  believe  they  met  the
"more-likely-than-not"  recognition  criteria,  and  accordingly  Kronos  had  a
deferred income tax asset valuation allowance offsetting the benefit of such net
operating loss carryforwards and Kronos' other tax attributes in Germany.  Prior
to the end of 2003, Kronos believed there was significant  uncertainty regarding
its ability to utilize such net operating  loss  carryforwards  under German tax
law and,  principally  because of this  uncertainty,  Kronos had  concluded  the
benefit   of  the  net   operating   loss   carryforwards   did  not   meet  the
"more-likely-than-not"  criteria.  By the end of 2003, and primarily as a result
of a  favorable  German  court  ruling  in 2003 and the  procedures  Kronos  had
completed  during 2003 with respect to the filing of certain  amended German tax
returns  (as  discussed  below),  Kronos  had  concluded  that  the  significant
uncertainty   regarding  its  ability  to  utilize  such  net   operating   loss
carryforwards  under German tax law had been eliminated.  However, at the end of
2003,  Kronos  believed that it would  generate a taxable loss in Germany during
2004.  Such  expectation  was based primarily upon then current levels of prices
for TiO2, and the fact that Kronos was experiencing a downward trend in its TiO2
selling  prices and Kronos did not have any  indication  that the downward trend
would improve. Accordingly, Kronos continued to conclude at the end of 2003 that
the  benefit of the German net  operating  loss  carryforwards  did not meet the
"more-likely-than-not"  criteria.  The expectation for a taxable loss in Germany
continued through the end of the first quarter of 2004. By the end of the second
quarter of 2004,  however,  Kronos' TiO2 selling prices had started to increase,
and Kronos  believes  its selling  prices will  continue to increase  during the
second  half  of 2004  after  Kronos  and its  major  competitors  announced  an
additional round of price increases.  Consequently,  Kronos' revised projections
now reflect  taxable  income for  Germany in 2004 as well as 2005.  Accordingly,
based on all available  evidence,  Kronos  concluded that the benefit of the net
operating  loss  carryforwards  and other  German  tax  attributes  now meet the
"more-likely-than-not"  recognition  criteria,  and Kronos reversed the deferred
income tax asset valuation  allowance  related to Germany.  Accordingly,  in the
first six months of 2004,  Kronos recognized a $254.3 million income tax benefit
related to the reversal of such deferred  income tax asset  valuation  allowance
attributable  to Kronos' income tax attributes in Germany  (principally  the net
operating loss  carryforwards).  Of such $254.3  million,  $8.7 million  relates
primarily to the  utilization  of the German net  operating  loss  carryforwards
during the first six months of 2004, the benefit of which had previously not met
the  "more-likely-than-not"  recognition criteria, and $245.6 million relates to
the German  deferred income tax asset  valuation  allowance  attributable to the
remaining German net operating loss carryforwards and other tax attributes as of
June  30,  2004,  the  benefit  of  which  Kronos  has  concluded  now  meet the
"more-likely-than-not" recognition criteria. At June 30, 2004, the net operating
loss  carryforwards  for German corporate and trade tax purposes  aggregated the
equivalent of $594 million and $255 million,  respectively, all of which have no
expiration date.

     In the first quarter of 2003, KII was notified by the German Federal Fiscal
Court that the Court had ruled in KII's favor concerning a claim for refund suit
in which KII sought  refunds of prior taxes paid during the periods 1990 through
1997. KII and KII's German  operating  subsidiary  were required to file amended
tax returns with the German tax  authorities to receive  refunds for such years,
and all of such amended  returns were filed  during 2003.  Such amended  returns
reflected an aggregate  net refund of taxes and related  interest to KII and its
German  operating  subsidiary  of euro 26.9  million  ($32.1  million),  and the
Company  recognized  the benefit  for these net  refunds in its 2003  results of
operations.  During  the first six  months of 2004,  the  Company  recognized  a
benefit of euro 2.5 million ($3.1  million)  related to additional  net interest
which has accrued on the  outstanding  refund  amounts.  Assessments and refunds
will be  processed  by year as the  respective  returns are  reviewed by the tax
authorities.  Certain interest components may also be refunded  separately.  The
German tax  authorities  have  reviewed and  accepted  the amended  returns with
respect  to the 1990 and  1991  tax  years.  Through  June  2004,  KII's  German
operating  subsidiary  had  received  net  refunds of euro 24.5  million  ($28.4
million when  received).  KII believes it will receive the  remainder of the net
refunds of taxes and related  interest during the remainder of 2004. In addition
to the refunds for the 1990 to 1997 periods, the court ruling also resulted in a
refund of 1999  income  taxes and  interest  for  which KII  received  euro 21.5
million ($24.6  million) in 2003, and the Company  recognized the benefit of the
refund in the second quarter of 2003.

     The Medicare  Prescription Drug,  Improvement and Modernization Act of 2003
(the "Medicare 2003 Act") introduced a prescription  drug benefit under Medicare
(Medicare  Part D) as well as a federal  subsidy to sponsors  of retiree  health
care  benefit  plans  that  provide  a  benefit  that  is at  least  actuarially
equivalent to Medicare Part D. Detailed  regulations  necessary to implement the
Medicare 2003 Act have not been issued,  including  those that would specify the
manner in which actuarial equivalency would be determined, the evidence required
to  demonstrate  actuarial   equivalence  and  the  documentation   requirements
necessary to receive the subsidy.  Until such definitive regulations are issued,
the Company is unable to determine whether the prescription drug benefit offered
under its  postretirement  benefit plans is at least  actuarially  equivalent to
Medicare Part D. Accordingly,  the Company's accumulated  postretirement benefit
obligation  and net periodic  postretirement  benefit  cost, as reflected in the
accompanying consolidated financial statements, do not reflect any effect of the
federal  subsidy.  When such definitive  regulations are issued or at such other
time that the  Company  can  determine  whether the  prescription  drug  benefit
offered  under  its  postretirement   benefit  plans  is  at  least  actuarially
equivalent  to Medicare  Part D, the Company would account for the effect of the
federal subsidy,  if any,  prospectively  from that date, as permitted by and in
accordance with FASB Staff Position No. 106-2.

Note 14 - Commitments and contingencies:

     Lead pigment  litigation.  The  Company's  former  operations  included the
manufacture of lead pigments for use in paint and lead-based paint.  Since 1987,
NL, other former manufacturers of lead pigments for use in paint, and lead-based
paint,  and  the  Lead  Industries   Association  (which  discontinued  business
operations in 2002) have been named as  defendants in various legal  proceedings
seeking  damages  for  personal   injury,   property  damage  and   governmental
expenditures  allegedly caused by the use of lead-based paints. Certain of these
actions  have been filed by or on behalf of states,  large U.S.  cities or their
public housing  authorities and school  districts,  and certain others have been
asserted as class  actions.  These  lawsuits  seek  recovery  under a variety of
theories,  including  public and private  nuisance,  negligent  product  design,
negligent   failure   to   warn,   strict   liability,   breach   of   warranty,
conspiracy/concert of action, aiding and abetting,  enterprise liability, market
share liability,  intentional  tort, fraud and  misrepresentation  violations of
state consumer protection statutes, supplier negligence and similar claims.

     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.  Several  former cases have been
dismissed or  withdrawn.  Most of the remaining  cases are in various  pre-trial
stages.  Some are on appeal  following  dismissal or summary judgment rulings in
favor of the defendants. In addition,  various other cases are pending (in which
the Company is not a defendant)  seeking recovery for injury allegedly caused by
lead pigment and  lead-based  paint.  Although the Company is not a defendant in
these cases,  the outcome of these cases may have an impact on additional  cases
being filed against the Company.

     NL believes  these actions are without  merit,  intends to continue to deny
all  allegations  of wrongdoing  and liability and to defend against all actions
vigorously.  NL has  neither  lost nor settled  any of these  cases.  NL has not
accrued  any  amounts  for  the  pending  lead  pigment  and  lead-based   paint
litigation.  Liability that may result,  if any, cannot reasonably be estimated.
There can be no assurance that NL 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.

     Environmental matters and litigation. The Company's operations are governed
by various federal, state, local and foreign environmental laws and regulations.
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 Company's  policy is to
comply  with  environmental  laws and  regulations  at all of its  plants and to
continually  strive to improve  environmental  performance in  association  with
applicable industry initiatives. The Company believes that its operations are in
substantial compliance with applicable  requirements of environmental laws. From
time to time, the Company may be subject to environmental regulatory enforcement
under various statutes, resolution of which typically involves the establishment
of  compliance  programs.  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.

     The  Company's  production   facilities  operate  within  an  environmental
regulatory  framework in which  governmental  authorities  typically are granted
broad  discretionary  powers that allow them to issue  operating  permits  under
which the plants must  operate.  The Company  believes  all of its plants are in
substantial  compliance with applicable  environmental laws. With respect to the
Company's  plants,  neither the Company  nor any of its  subsidiaries  have been
notified  of  any  environmental  claim  in the  United  States  or any  foreign
jurisdiction  by  the  U.S.  Environmental  Protection  Agency  ("EPA")  or  any
applicable foreign authority or any state, provincial or local authority.

     Some of the Company's  current and former  facilities,  including  divested
primary and 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 as a  defendant,  potentially
responsible party ("PRP") or both,  pursuant to the Comprehensive  Environmental
Response, Compensation and Liability Act, as amended by the Superfund Amendments
and  Reauthorization  Act ("CERCLA") and similar state laws in  approximately 60
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.

     Environmental obligations are difficult to assess and estimate for numerous
reasons including the complexity and differing  interpretations  of governmental
regulations,  the number of PRPs and the PRPs'  ability or  willingness  to fund
such  allocation of costs,  their financial  capabilities  and the allocation of
costs among PRPs,  the  solvency of other  PRPs,  the  multiplicity  of possible
solutions,  and the years of  investigatory,  remedial and  monitoring  activity
required.   In  addition,   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,
solvency of other PRPs,  the results of future  testing and analysis  undertaken
with respect to certain sites 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. In addition,  with respect to other PRPs and the fact
that the Company may be jointly and severally  liable for the total  remediation
cost at certain  sites,  the Company  could  ultimately be liable for amounts in
excess of its accruals due to, among other things,  reallocation  of costs among
PRPs or the  insolvency  of one or more  PRPs.  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.

     A summary of the  activity in the  Company's  accrued  environmental  costs
during the first six months of 2004 is presented in the table below. The Company
recognized a net reduction in its accrued environmental costs credited to income
during the first six months of 2004 due  primarily to the $1.5 million  recovery
discussed  below.  The amount shown in the table below for payments  against the
Company's accrued environmental costs is net of such $1.5 million recovery.


                                                          Amount

     The  Company  records  liabilities  related  to  environmental  remediation
obligations  when  estimated  future  expenditures  are probable and  reasonably
estimable.  Such accruals are adjusted as further  information becomes available
or  circumstances  change.  Estimated  future  expenditures  are  generally  not
discounted to their present value.  Recoveries of  remediation  costs from other
parties, if any, are recognized as assets when their receipt is deemed probable.
At June 30, 2004, NL had recognized a $1.5 million receivable from other PRPs at
one site for recovery of remediation costs previously expended by NL pursuant to
an agreement  entered into by NL and such other PRPs.  NL expects to receive the
$1.5 million recovery during the third quarter of 2004.

     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,  including
sites for which EMS has contractually assumed NL's obligation. At June 30, 2004,
the Company had accrued $73 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 for which it is possible  to estimate  costs is  approximately
$101  million.  The  Company's  estimates  of such  liabilities  have  not  been
discounted to present value.

     The exact time frame over which the Company makes  payments with respect to
its accrued  environmental  costs is unknown and is dependent upon,  among other
things,  the timing of the actual  remediation  process which in part depends on
factors  outside the control of the  Company.  At each balance  sheet date,  the
Company makes an estimate of the amount of its accrued environmental costs which
will be paid out over the subsequent 12 months,  and the Company classifies such
amount as a current liability.  The remainder of the accrued environmental costs
is classified as a noncurrent liability.

     At June 30, 2004, there are approximately 15 sites for which the Company is
unable  to  estimate  a  range  of  costs.   For  these  sites,   generally  the
investigation is in the early stages,  and it is either unknown as to whether or
not the Company  actually had any  association  with the site, or if the Company
did have  association with the site, the nature of its  responsibility,  if any,
for the contamination at the site and the extent of contamination. The timing on
when  information  would become available to the Company to allow the Company to
estimate a range of loss is unknown and dependent on events  outside the control
of the Company,  such as when the party alleging liability provides  information
to the Company.

     At  June  30,  2004,  the  Company  had $17  million  in  restricted  cash,
restricted cash  equivalents  and restricted  marketable debt securities held by
special purpose trusts,  the assets of which can only be used to pay for certain
of the  Company's  future  environmental  remediation  and  other  environmental
expenditures  (December 31, 2003 - $24 million). Use of such restricted balances
does not affect the Company's Consolidated Statements of Cash Flows.

     Other  litigation.  The Company  has been named as a  defendant  in various
lawsuits in a variety of  jurisdictions,  alleging personal injuries as a result
of  occupational  exposure to asbestos,  silica  and/or mixed dust in connection
with formerly owned  operations.  Approximately  485 of these cases  involving a
total of approximately  30,000  plaintiffs and their spouses remain pending.  Of
these plaintiffs, approximately 18,400 are represented by eight cases pending in
Mississippi  state  court.  The  Company  has not  accrued  any amounts for this
litigation because liability that might result to the Company, if any, cannot be
reasonably estimated.  In addition,  from time to time, the Company has received
notices  regarding  asbestos or silica claims  purporting to be brought  against
former subsidiaries of the Company,  including notices provided to insurers with
which the Company has entered into settlements  extinguishing  certain insurance
policies. These insurers may seek indemnification from the Company.

     In addition to the litigation described above, the Company is also involved
in various other environmental, contractual, product liability, patent (or other
intellectual  property),  employment and other claims and disputes incidental to
its present and former  businesses.  In certain cases, the Company has insurance
coverage for such items. The Company  currently  believes the disposition of all
of these 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.

     Note 15 - Accounting principle newly adopted in 2004:

     The Company  complied with the  consolidation  requirements of FIN No. 46R,
"Consolidation of Variable Interest Entities,  an interpretation of ARB No. 51,"
as amended, as of March 31, 2004. The Company does not have any involvement with
any variable interest entity (as that term is defined in FIN No. 46R) covered by
the scope of FIN No. 46R which had not  already  been  consolidated  under prior
applicable  GAAP,  and  therefore  the  impact to the  Company of  adopting  the
consolidation requirements of FIN No. 46R was not material.







ITEM 2. MANAGEMENT'S  DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS
OF OPERATIONS
- --------------------------------------------------------------------------------

RESULTS OF OPERATIONS:

Executive summary

     At June 30, 2004, the Company  conducts  operations for the manufacture and
sales of TiO2, its principal product,  through its subsidiary,  Kronos. Relative
changes in the Company's  sales and income from  operations  related to its TiO2
business  during  the second  quarter  and first six months of 2003 and 2004 are
primarily  due to (i)  relative  changes in average TiO2  selling  prices,  (ii)
relative  changes in TiO2 sales  volumes and (iii)  relative  changes in foreign
currency  exchange rates.  Selling prices were generally  increasing  during the
first quarter of 2003,  were  generally  flat during the second quarter of 2003,
were generally  decreasing  during the third and fourth quarters of 2003 and the
first quarter of 2004 and were generally flat during the second quarter of 2004.

     The Company  reported  net income of $179.0  million,  or $3.70 per diluted
share, in the second quarter of 2004 compared to net income of $28.8 million, or
$.60 per diluted share,  in the second quarter of 2003. For the first six months
of 2004, the Company reported net income of $183.1 million, or $3.79 per diluted
share,  compared to net income of $38.3 million,  or $.80 per diluted share,  in
the first six months of 2003. The increase in the Company's diluted earnings per
share from the first quarter and first six months of 2003 to the same periods in
2004 is due primarily to the net effects of (i) significantly higher tax benefit
generated  from the  reversal  of  Kronos'  German  deferred  income  tax  asset
valuation  allowance  and tax benefits  related to EMS, (ii) lower gross margins
generated at Kronos, (iii) higher selling,  general and administrative  expenses
at  Kronos,  (iv)  income  from a  contract  dispute  settlement  with a  Kronos
customer, (iv) lower environmental  remediation and legal expenses of NL and (v)
higher minority interest in Kronos. Overall, the Company believes its net income
in 2004 will be higher  than 2003 as the impact of the  reversal  of Kronos' and
EMS' deferred  income tax asset  valuation  allowances are expected to more than
offset the effect of Kronos' expected lower income from operations.

     The Company  believes the  analysis  presented  in the  following  table is
useful in understanding  the  comparability of its results of operations for the
2003 and 2004 periods  presented.  Each of these items are more fully  discussed
below in the applicable  sections of this "Management's  Discussion and Analysis
of Financial  Condition and Results of Operations - Results of Operations" or in

_______________________________

(1)  Kronos'  reversal  of  its  German  deferred  income  tax  asset  valuation
     allowance as of June 30, 2004.
(2)  Reversal of the deferred  income tax asset valuation  allowance  related to
     EMS and adjustment of estimated tax due upon IRS settlement.
(3)  Kronos' income from settlement of customer contract.
(4)  Refund of prior year German income taxes received.

     As discussed in Note 1 to the Consolidated  Financial  Statements,  in July
2004 the Company  paid its regular  quarterly  dividend of $.20 per share in the
form of shares of Kronos common stock in which approximately 322,000 shares were
distributed.  After considering such 2004 distribution,  the Company's ownership
of Kronos will be reduced  from 50.5% to  approximately  49.8%,  and the Company
will no longer own a majority of Kronos' outstanding common stock. Consequently,
effective  in the third  quarter of 2004 the Company  will cease to  consolidate
Kronos' financial position, results of operations and cash flows and instead the
Company  will  commence  accounting  for its  interest  in Kronos by the  equity
method.

Forward-looking information

     As  provided  by the  safe  harbor  provisions  of the  Private  Securities
Litigation  Reform Act of 1995, the Company cautions that the statements in this
Quarterly  Report on Form 10-Q relating to matters that are not historical facts
are  forward-looking   statements  that  represent   management's   beliefs  and
assumptions based on currently available information. Forward-looking statements
can be  identified  by the use of words such as  "believes,"  "intends,"  "may,"
"should," "could,"  "anticipates,"  "expects" or comparable  terminology,  or by
discussions  of  strategies  or trends.  Although the Company  believes that the
expectations  reflected in such  forward-looking  statements are reasonable,  it
cannot give any  assurances  that these  expectations  will prove to be correct.
Such statements by their nature involve substantial risks and uncertainties that
could  significantly  impact expected  results,  and actual future results could
differ materially from those described in such forward-looking statements. While
it is not possible to identify all factors,  the Company  continues to face many
risks and  uncertainties.  Among the  factors  that could  cause  actual  future
results to differ materially are the risks and  uncertainties  discussed in this
Quarterly  Report and those  described from time to time in the Company's  other
filings with the Securities and Exchange  Commission ("SEC") including,  but not
limited to, the following:

o    Future supply and demand for the Company's products,
o    The cyclicality of the Company's businesses,
o    Customer  inventory  levels (such as the extent to which Kronos'  customers
     may,  from  time to  time,  accelerate  purchases  of TiO2  in  advance  of
     anticipated  price  increases  or defer  purchases  of TiO2 in  advance  of
     anticipated price decreases),
o    Changes in raw material and other operating costs (such as energy costs),
o    The possibility of labor disruptions,
o    General global  economic and political  conditions  (such as changes in the
     level of gross  domestic  product in  various  regions of the world and the
     impact of such changes on demand for TiO2),
o    Competitive products and substitute products,
o    Customer and competitor strategies,
o    The impact of pricing and production decisions,
o    Competitive technology positions,
o    Fluctuations  in currency  exchange  rates (such as changes in the exchange
     rate between the U.S. dollar and each of the euro, the Norwegian kroner and
     the Canadian dollar),
o    Operating  interruptions  (including,  but not limited to, labor  disputes,
     leaks,   fires,   explosions,   unscheduled   or  unplanned   downtime  and
     transportation interruptions),
o    The ability of the Company to renew or refinance credit facilities,
o    The ultimate  outcome of income tax audits,  tax settlement  initiatives or
     other tax matters,
o    The ultimate ability to utilize income tax attributes, the benefit of which
     has been recognized under the "more-likely-than-not" recognition criteria,
o    Environmental  matters  (such as those  requiring  emission  and  discharge
     standards for existing and new facilities),
o    Government  laws and  regulations  and possible  changes  therein  (such as
     changes in government regulations which might impose various obligations on
     present and former  manufacturers  of lead  pigment and  lead-based  paint,
     including NL, with respect to asserted health concerns  associated with the
     use of such products),
o    The ultimate  resolution of pending  litigation  (such as NL's lead pigment
     litigation and litigation surrounding environmental matters) and
o    Possible future litigation.

     Should one or more of these risks  materialize (or the consequences of such
a development  worsen),  or should the underlying  assumptions  prove incorrect,
actual results could differ  materially from those  forecasted or expected.  The
Company   disclaims  any  intention  or  obligation  to  update  or  revise  any
forward-looking statement whether as a result of new information,  future events
or otherwise.

 *  Thousands of metric tons

     Kronos' sales  increased  $29.2 million (11%) in the second quarter of 2004
compared to the second  quarter of 2003 and increased  $39.5 million (8%) in the
first six months of 2004  compared to the same period in 2003,  as the favorable
effect of fluctuations in foreign currency exchange rates, which increased sales
by  approximately  $13 million  and $35  million,  respectively,  (as more fully
discussed  below) and increased  sales  volumes,  more than offset the impact of
lower average TiO2 selling  prices.  Excluding the effect of fluctuations in the
value of the U.S.  dollar  relative to other  currencies,  Kronos'  average TiO2
selling prices in billing currencies in the second quarter of 2004 were 5% lower
than the  second  quarter  of 2003 and in the first  six  months of 2004 were 5%
lower than the first six months of 2003. When translated from billing currencies
into U.S. dollars using actual foreign currency exchange rates prevailing during
the  respective  periods,  Kronos'  average  TiO2  selling  prices in the second
quarter of 2004 were  comparable to the second  quarter of 2003 and increased 2%
in the year to date period. Kronos' TiO2 sales volumes in the second quarter and
first six months of 2004  increased  13% and 6%,  respectively,  compared to the
same periods of 2003, as higher volumes in European and export markets more than
offset  lower  volumes in Canada.  Kronos'  TiO2 sales  volumes in the first six
months of 2004 were a new record for Kronos.

     Kronos' sales are  denominated  in various  currencies,  including the U.S.
dollar,  the euro, other major European  currencies and the Canadian dollar. The
disclosure of the  percentage  change in Kronos'  average TiO2 selling prices in
billing  currencies  (which excludes the effects of fluctuations in the value of
the U.S.  dollar  relative  to other  currencies)  is  considered  a  "non-GAAP"
financial measure under regulations of the SEC. The disclosure of the percentage
change in Kronos'  average TiO2 selling  prices  using actual  foreign  currency
exchange rates prevailing  during the respective  periods is considered the most
directly  comparable  financial  measure presented in accordance with accounting
principles  generally  accepted in the United  States ("GAAP  measure").  Kronos
discloses  percentage  changes in its average TiO2 prices in billing  currencies
because Kronos believes such disclosure provides useful information to investors
to allow them to analyze such  changes  without the impact of changes in foreign
currency exchange rates,  thereby facilitating  period-to-period  comparisons of
the relative  changes in average  selling prices in the actual  various  billing
currencies.  Generally,  when the U.S.  dollar  either  strengthens  or  weakens
against other  currencies,  the percentage  change in average  selling prices in
billing currencies will be higher or lower,  respectively,  than such percentage
changes would be using actual  exchange rates  prevailing  during the respective
periods.  The  difference  between the less than 1% decrease  and 2% increase in
Kronos'  average TiO2  selling  prices  during the second  quarter and first six
months of 2004,  respectively,  as  compared  to the same  periods in 2003 using
actual foreign currency exchange rates prevailing during the respective  periods
(the GAAP measure) and the 5% decrease in Kronos'  average TiO2 selling price in
billing  currencies (the non-GAAP measure) during each of such periods is due to
the effect of  changes  in foreign  currency  exchange  rates.  The above  table
presents (i) the percentage  change in Kronos' average TiO2 selling prices using
actual foreign currency exchange rates prevailing during the respective  periods
(the GAAP measure),  (ii) the percentage  change in Kronos' average TiO2 selling
prices in billing  currencies  (the non-GAAP  measure) and (iii) the  percentage
change due to changes in foreign  currency  exchange  rates (or the  reconciling
item between the non-GAAP measure and the GAAP measure).

     Kronos' cost of sales  increased  $29.9 million (15%) in the second quarter
of 2004  compared to the second  quarter of 2003,  and  increased  $43.7 million
(11%) in the year-to-date period largely due to the higher sales volumes and the
effects  of  translating  foreign  currencies  (primarily  the  euro)  into U.S.
dollars.  As a result of the  lower  average  TiO2  selling  prices  in  billing
currencies,  Kronos' cost of sales as a percentage of net sales,  increased from
74% in each of the  second  quarter  and the first six  months of 2003 to 77% in
each of the  second  quarter  and the first six  months  of 2004.  Kronos'  TiO2
production  volumes in the second  quarter of 2004  increased 3% compared to the
second quarter of 2003,  and increased 1% in the first six months of 2004,  with
operating  rates near full capacity in those  periods.  Kronos' TiO2  production
volumes in the first six months of 2004 were also a new record for Kronos.

     Despite the  increase in net sales,  Kronos'  gross  margins for the second
quarter of 2004  decreased  $700,000  (1%) from the  second  quarter of 2003 and
decreased $4.2 million (3%) from the first half of 2003 as compared to the first
half of 2004, as the  unfavorable  effect of lower  average TiO2 selling  prices
more than offset the favorable  effect on gross margin  resulting  from relative
changes in foreign currency exchange rates.

     Reflecting  the impact of partial  implementation  of prior price  increase
announcements, Kronos' average TiO2 selling prices in the second quarter of 2004
were  generally  flat as compared to the first quarter of 2004.  Kronos has also
recently announced  additional price increases of 4 cents per pound in the U.S.,
Canadian 6 cents per pound in Canada and euro 120 per metric ton in Europe,  all
of which are targeted to be  implemented  later in 2004. The extent to which all
of such price  increase  announcements  will be realized  will depend on,  among
other things, economic factors.

     Selling,  general and administrative  expenses increased $4.0 million (13%)
and $9.8 million (16%), respectively, in the second quarter and first six months
of 2004 as compared to the  corresponding  periods in 2003.  These increases are
largely  attributable  to the  higher  sales  volumes  as well as the  impact of
translating foreign currencies (primarily the euro) into U.S. dollars.

     Kronos' income from  operations in the second quarter of 2004 also includes
$6.3 million of income related to the settlement of a certain  contract  dispute
with a customer. As part of the settlement, the customer agreed to make payments
to Kronos through 2007  aggregating  $7.3 million.  The $6.3 million  recognized
gain  represents  the  present  value of the future  payments  to be paid by the
customer to Kronos.

     Kronos has  substantial  operations and assets  located  outside the United
States  (particularly  in Germany,  Belgium,  Norway and Canada).  A significant
amount of Kronos' sales  generated from its non-U.S.  operations are denominated
in  currencies  other than the U.S.  dollar,  primarily  the euro,  other  major
European  currencies and the Canadian dollar. In addition,  a portion of Kronos'
sales generated from its non-U.S. operations are denominated in the U.S. dollar.
Certain raw materials,  primarily titanium-containing  feedstocks, are purchased
in U.S.  dollars,  while  labor  and  other  production  costs  are  denominated
primarily in local currencies. Consequently, the translated U.S. dollar value of
Kronos'  foreign  sales and operating  results are subject to currency  exchange
rate fluctuations  which may favorably or adversely impact reported earnings and
may affect the comparability of  period-to-period  operating  results.  Overall,
fluctuations  in the  value of the U.S.  dollar  relative  to other  currencies,
primarily  the euro,  increased  TiO2  sales in the  second  quarter  of 2004 by
approximately $13 million compared to the same period in 2003 and increased TiO2
sales in the first six months of 2004 by  approximately  $35 million compared to
the same period in 2003.  Fluctuations  in the value of the U.S. dollar relative
to other  currencies  similarly  impacted  Kronos' foreign  currency-denominated
operating expenses. Kronos' operating costs that are not denominated in the U.S.
dollar, when translated into U.S. dollars, were higher in the second quarter and
first six months of 2004 compared to the second  quarter and first six months of
2003. Overall,  currency exchange rate fluctuations resulted in net increases in
Kronos' income from operations of approximately $6 million and $8 million in the
second  quarter and first six months of 2004,  respectively,  as compared to the
same periods in 2003.

     Corporate  expense  for the second  quarter of 2004  decreased  80% to $4.6
million as compared  to the second  quarter of 2003 and  decreased  71% to $11.3
million for the first six months of 2004 as compared to the comparable period in
2003  primarily  due to lower  environmental  remediation  and  legal  expenses.
Corporate  expenses are expected to continue to be lower for the full-year  2004
as  compared  to  full-year  2003.   However,   obligations  for   environmental
remediation are difficult to assess and estimate,  and no assurance can be given
that  actual  costs  will not exceed  accrued  amounts or that costs will not be
incurred  with respect to sites for which no estimate of liability can presently
be made. See Note 14 to the Consolidated Financial Statements.

Outlook

     The Company expects  Kronos' TiO2 sales and production  volumes in calendar
2004 will be higher as compared to 2003.  Kronos'  average Ti02  selling  price,
which  declined  during  the  second  half of 2003 and  first  quarter  of 2004,
commenced  to begin to rise  during  the  second  quarter  of 2004,  and  should
continue to rise during the remainder of the year. Nevertheless,  Kronos expects
its  average  TiO2  selling  prices,  in  billing  currencies,  will be lower in
calendar  2004 as compared  to 2003 and  expects its gross  margin in 2004 to be
lower than 2003. The Company's  expectations  as to the future  prospects of the
Company  and the TiO2  industry  are based upon a number of  factors  beyond its
control,  including  worldwide growth of gross domestic product,  competition in
the  marketplace,  unexpected or  earlier-than-expected  capacity  additions and
technological  advances.  If  actual  developments  differ  from  the  Company's
expectations, the Company's results of operations could be unfavorably affected.

     Kronos has a significant amount of outstanding  indebtedness denominated in
the euro,  including  KII's euro 285 million Senior Secured Notes.  Accordingly,
the reported amount of interest  expense will vary depending on relative changes
in foreign  currency  exchange rates.  Interest expense in the second quarter of
2004 was $8.6 million,  an increase of $300,000 from the second quarter of 2003.
Interest expense in the first six months of 2004 was $17.8 million,  an increase
of $1.4  million  from the first  six  months of 2003.  The  increases  were due
primarily  to  relative  changes  in  foreign  currency  exchange  rates,  which
increased  the U.S.  dollar  equivalent  of  interest  expense on the KII Senior
Secured  Notes  by  approximately  $600,000  in the  second  quarter  of 2004 as
compared to the first  quarter of 2003 and $1.7  million in the first six months
of 2004 as  compared to the first six months of 2003.  Assuming  no  significant
change in interest rates or foreign  currency  exchange rates,  interest expense
for the  full-year  2004 is expected to be slightly  higher than amounts for the
same period in 2003.

Provision for income taxes

     The principal  reasons for the difference  between the Company's  effective
income tax rate and the U.S. federal statutory income tax rates are explained in
Note 11 to the Consolidated Financial Statements.

     At June 30,  2004,  Kronos  had the  equivalent  of $594  million  and $255
million,  respectively, of net operating loss carryforwards for German corporate
and trade tax  purposes,  all of which have no  expiration  date.  As more fully
described  in Note  11 to the  Consolidated  Financial  Statements,  Kronos  had
previously  provided a deferred  income tax asset  valuation  allowance  against
substantially all of these tax loss carryforwards and other deductible temporary
differences   in  Germany   because   Kronos  did  not  believe   they  met  the
"more-likely-than-not"  recognition  criteria.  During  the first six  months of
2004,  Kronos  reduced its  deferred  income tax asset  valuation  allowance  by
approximately $8.7 million, primarily as a result of utilization of these German
net operating loss  carryforwards,  the benefit of which had not previously been
recognized.  At June 30, 2004, after considering all available evidence,  Kronos
concluded  that  these  German  tax  loss  carryforwards  and  other  deductible
temporary differences now meet the "more-likely-than-not"  recognition criteria.
Accordingly,  as of June 30, 2004,  Kronos reversed the remaining $245.6 million
valuation  allowance  related to such  items.  Because  the  benefit of such net
operating  loss  carryforwards  and other  deductible  temporary  differences in
Germany has now been recognized,  the Company's future effective income tax rate
will be higher than what it would have otherwise been,  although its future cash
income tax rate would not be affected.

     In  January  2004,  the  German  federal  government  enacted  new  tax law
amendments  that limit the annual  utilization of income tax loss  carryforwards
effective  January  1, 2004 to 60% of  taxable  income  after  the first  euro 1
million of taxable income. The new law will have a significant effect on Kronos'
cash tax  payments  in  Germany  going  forward,  the  extent  of which  will be
dependent on the level of income earned in Germany.

Minority interest

     See Note 9 to the Consolidated Financial Statements.  The Company commenced
recognizing  minority  interest in Kronos following the Company's  December 2003
distribution  of a portion of the shares of Kronos common stock to the Company's
shareholders.  Because of such  distribution,  the  Company  expects to report a
higher  amount of  minority  interest  in  earnings in 2004 as compared to 2003.
Subsequent to the payment of the Company's July 2004  quarterly  dividend in the
form of shares of Kronos common stock in which  approximately  322,000 shares of
Kronos were distributed,  the Company's ownership of Kronos will be reduced from
50.5% to  approximately  49.8%, and the Company will no longer own a majority of
Kronos' outstanding common stock.  Consequently,  effective in the third quarter
of 2004 the  Company  will cease to  consolidate  Kronos and instead the Company
will commence  accounting  for its interest in Kronos by the equity  method,  at
which time the Company will no longer report minority interest in Kronos.

     Minority  interest  in NL's  subsidiaries  also  relates  to the  Company's
majority-owned  environmental management subsidiary, EMS. EMS was established in
1998,  at  which  time  EMS  contractually  assumed  certain  of  the  Company's
environmental liabilities. EMS' earnings are based, in part, upon its ability to
favorably  resolve these  liabilities on an aggregate basis. The shareholders of
EMS, other than the Company,  actively manage the environmental  liabilities and
share in 39% of EMS' cumulative  earnings.  The Company continues to consolidate
EMS and provides accruals for the reasonably  estimable costs for the settlement
of EMS' environmental liabilities, as discussed below.

Operating activities

     The TiO2 industry is cyclical and changes in economic conditions within the
industry  significantly  impact the  earnings  and  operating  cash flows of the
Company. Cash flow from operations is considered the primary source of liquidity
for the Company. Changes in TiO2 pricing, production volume and customer demand,
among other  things,  could  significantly  affect the liquidity of the Company.
Trends  in cash  flows  from  operating  activities  (excluding  the  impact  of
significant  asset  dispositions and relative changes in assets and liabilities)
are generally  similar to trends in the  Company's  earnings.  However,  certain
items included in the  determination  of net income are non-cash,  and therefore
such  items have no impact on cash flows  from  operating  activities.  Non-cash
items  included in the  determination  of net income  include  depreciation  and
amortization  expense,  deferred  income  taxes and non-cash  interest  expense.
Non-cash  interest  expense  relates  principally  to  Kronos  and  consists  of
amortization of deferred financing costs.

     Certain other items included in the determination of net income may have an
impact on cash flows from operating activities,  but the impact of such items on
cash  flows from  operating  activities  will  differ  from their  impact on net
income. For example, the amount of periodic defined benefit pension plan expense
and periodic OPEB expense  depends upon a number of factors,  including  certain
actuarial assumptions,  and changes in such actuarial assumptions will result in
a change in the reported expense.  The amount of such periodic expense generally
differs  from  the  outflows  of cash  required  to be  currently  paid for such
benefits.

     Relative changes in assets and liabilities generally result from the timing
of production,  sales, purchases and income tax payments.  Such relative changes
can  significantly  impact the  comparability  of cash flow from operations from
period to period,  as the income  statement  impact of such items may occur in a
different period from when the underlying cash transaction  occurs. For example,
raw  materials  may be  purchased  in one  period,  but the payment for such raw
materials may occur in a subsequent period. Similarly,  inventory may be sold in
one period,  but the cash collection of the receivable may occur in a subsequent
period.

     Cash flows from operating  activities increased from $18.7 million provided
by operating activities in the first six months of 2003 to $58.0 million of cash
provided by  operating  activities  in the first six months of 2004.  This $39.3
million  increase was due  primarily to the net effects of (i) higher net income
of $144.9 million, (ii) higher depreciation expense of $2.3 million, (iii) lower
deferred  income  taxes of $285.5  million,  (iv)  higher  minority  interest in
earnings  of  $137.7  million,  (v)  higher  net  distributions  from  the  TiO2
manufacturing  joint  venture of $8.3 million in the first half of 2004 compared
to an $800,000  distribution  in the first half of 2003, (vi) a higher amount of
net cash used from relative changes in the Company's  inventories,  receivables,
payables  and  accruals  of $15.7  million  in the first  six  months of 2004 as
compared  to the first six  months of 2003 and (vii)  lower cash paid for income
taxes of $28.2 million. Relative changes in accounts receivable are affected by,
among other  things,  the timing of sales and the  collection  of the  resulting
receivables.  Relative  changes in inventories and accounts  payable and accrued
liabilities  are  affected by,  among other  things,  the timing of raw material
purchases and the payment for such purchases and the relative difference between
production volumes and sales volumes.  Relative changes in accrued environmental
costs are affected by, among other things,  the period in which  recognition  of
the environmental  accrual is recognized and the period in which the remediation
expenditure is actually made.

     NL does not have complete access to the cash flows of its  subsidiaries and
affiliates, in part due to limitations contained in certain credit agreements as
well as the fact that certain of such  subsidiaries  and affiliates are not 100%
owned by NL. A detail of NL's consolidated cash flows from operating  activities
is presented in the table below.  Eliminations consist of intercompany dividends
(most of which are paid by Kronos to NL).

Investing and financing activities

     The Company's capital  expenditures were $13.9 million and $10.9 million in
the first  six  months of 2003 and 2004,  respectively,  the  majority  of which
relate to Kronos.

     In the first  quarter  of 2004 KII's  operating  subsidiaries  in  Germany,
Belgium and Norway  borrowed a net euro 26 million ($32  million when  borrowed)
under the European  revolving  credit facility at an interest rate of 3.8%. Such
amounts were repaid in the second quarter of 2004.

     In each of the first two quarters of 2004,  Kronos paid a regular quarterly
cash dividend to its  stockholders of $.25 per share, of which $12.0 million was
paid to Kronos  shareholders other than NL and is reflected as a distribution to
minority interest on NL's Consolidated Statements of Cash Flows.

     At June 30, 2004,  unused credit  available  under Kronos'  existing credit
facilities  approximated $150 million, which was comprised of: $95 million under
its European  revolving credit  facility,  $11 million under its Canadian credit
facility,  $40 million under its U.S. credit facility and $4 million under other
non-US  facilities.  At June  30,  2004,  KII  had  approximately  $220  million
available for payment of dividends and other restrictive  payments as defined in
the Senior Secured Notes indenture.

     Provisions  contained in certain of Kronos' credit  agreements could result
in the acceleration of the applicable  indebtedness prior to its stated maturity
for reasons other than  defaults  from failing to comply with typical  financial
covenants. For example, certain credit agreements allow the lender to accelerate
the  maturity of the  indebtedness  upon a change of control (as defined) of the
borrower.   In  addition,   certain  credit   agreements  could  result  in  the
acceleration of all or a portion of the indebtedness  following a sale of assets
outside the ordinary course of business.  Other than operating  leases discussed
in the 2003 Annual Report,  neither NL nor any of its subsidiaries or affiliates
are parties to any off-balance sheet financing arrangements.

Kronos Worldwide, Inc.

     At June 30, 2004,  Kronos had cash,  cash  equivalents  and marketable debt
securities of $92.0 million,  including restricted balances of $3.5 million, and
Kronos had $150  million  available  for  borrowing  under its U.S. and non-U.S.
credit facilities.

     At June 30,  2004,  Kronos'  outstanding  debt was  comprised of (i) $346.4
million related to KII's Senior Secured Notes and (ii) approximately $400,000 of
other  indebtedness.  In  addition,  Kronos had a $200  million  long-term  note
payable to NL due in 2010,  which is eliminated  in the  Company's  consolidated
financial statements.

     Pricing  within the TiO2  industry  is  cyclical,  and  changes in industry
economic  conditions  significantly  impact Kronos'  earnings and operating cash
flows.  Cash flows from operations is considered the primary source of liquidity
for Kronos.  Changes in TiO2  pricing,  production  volume and customer  demand,
among other things, could significantly affect the liquidity of Kronos.

     See Note 11 to the Consolidated Financial Statements for certain income tax
examinations  currently  underway with respect to certain of Kronos'  income tax
returns in  various  U.S.  and  non-U.S.  jurisdictions,  and see Note 14 to the
Consolidated Financial Statements with respect to certain legal proceedings with
respect to Kronos.

     Kronos periodically evaluates its liquidity requirements,  alternative uses
of capital,  capital needs and availability of resources in view of, among other
things,  its  dividend  policy,   its  debt  service  and  capital   expenditure
requirements  and estimated  future  operating  cash flows.  As a result of this
process, Kronos has in the past and may in the future seek to reduce, refinance,
repurchase or restructure  indebtedness,  raise additional  capital,  repurchase
shares of its common stock,  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,  Kronos  may  review  opportunities  for
acquisitions, divestitures, joint ventures or other business combinations in the
chemicals or other  industries,  as well as the acquisition of interests in, and
loans to, related  entities.  In the event of any such  transaction,  Kronos may
consider using its available cash,  issuing its equity  securities or increasing
its  indebtedness to the extent  permitted by the agreements  governing  Kronos'
existing debt.

     Kronos has  substantial  operations  located  outside the United States for
which the functional  currency is not the U.S. dollar. As a result, the reported
amounts of Kronos' assets and  liabilities  related to its non-U.S.  operations,
and therefore Kronos' and the Company's  consolidated net assets, will fluctuate
based upon changes in currency exchange rates.



NL Industries

     At June 30,  2004,  NL,  exclusive of Kronos and its  subsidiaries  had (i)
current  cash and cash  equivalents  aggregating  $27.3  million,  (ii)  current
restricted cash equivalents of $9.9 million, (iii) current restricted marketable
debt securities of $9.1 million and (iv) noncurrent  restricted  marketable debt
securities of $6.9 million. Of such restricted balances, $17 million was held by
special purpose trusts,  the assets of which can only be used to pay for certain
of NL's future environmental  remediation and other environmental  expenditures.
NL also has a $200 million  long-term note  receivable  from Kronos due in 2010,
which is eliminated in the Company's consolidated financial statements.

     See Note 11 to the Consolidated Financial Statements for certain income tax
examinations  currently  underway  with  respect to  certain of NL's  income tax
returns,  and see Note 14 to the Consolidated  Financial Statements and Part II,
Item 1,  "Legal  Proceedings"  with  respect to certain  legal  proceedings  and
environmental matters with respect to NL.

     In December 2003, NL completed the distribution of  approximately  48.8% of
Kronos' outstanding common stock to its shareholders under which NL shareholders
received  one share of  Kronos'  common  stock for every two shares of NL common
stock  held.  Approximately  23.9  million  shares of Kronos  common  stock were
distributed.  Immediately  prior to the  distribution of shares of Kronos common
stock,  Kronos  distributed a $200 million  promissory note payable by Kronos to
NL. In March 2004, NL paid its $.20 per share regular quarterly  dividend in the
form of  shares  of  Kronos  common  stock.  Approximately  345,100  shares,  or
approximately .7% of Kronos'  outstanding  common stock, were distributed.  NL's
second  quarter  dividend of $.20 per share,  also paid in the form of shares of
Kronos  common stock,  was paid in July 2004.  Approximately  322,000  shares of
Kronos,  or  approximately  .7%  of  Kronos'   outstanding  common  stock,  were
distributed in this distribution. Following this distribution, NL no longer owns
a majority of Kronos' outstanding common stock, and accordingly NL will cease to
consolidate Kronos as of July 1, 2004.

     NL periodically evaluates its liquidity  requirements,  alternative uses of
capital,  capital  needs and  availability  of resources in view of, among other
things,  its  dividend  policy,   its  debt  service  and  capital   expenditure
requirements  and estimated  future  operating  cash flows.  As a result of this
process,  NL has in the past and may in the future  seek to  reduce,  refinance,
repurchase or restructure  indebtedness,  raise additional  capital,  repurchase
shares of its common stock,  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, NL may review opportunities for acquisitions,
divestitures,  joint ventures or other business combinations in the chemicals or
other  industries,  as well as the  acquisition  of interests  in, and loans to,
related entities.  In the event of any such  transaction,  NL may consider using
its available cash, issuing its equity securities or increasing its indebtedness
to the extent permitted by the agreements governing NL's existing debt.

Non-GAAP financial measures

     In an effort to provide investors with additional information regarding the
Company's results of operations as determined by GAAP, the Company has disclosed
certain  non-GAAP   information  which  the  Company  believes  provides  useful
information to investors.

o    The Company  discloses  percentage  changes in Kronos' average TiO2 selling
     prices in  billing  currencies,  which  excludes  the  effects  of  foreign
     currency  translation.  The Company believes  disclosure of such percentage
     changes  allows  investors to analyze  such  changes  without the impact of
     changes  in  foreign   currency   exchange  rates,   thereby   facilitating
     period-to-period  comparisons  of the relative  changes in average  selling
     prices in the actual various billing currencies.  Generally,  when the U.S.
     dollar  either  strengthens  or  weakens  against  other  currencies,   the
     percentage  change in average selling prices in billing  currencies will be
     higher or lower, respectively,  than such percentage changes would be using
     actual exchange rates prevailing during the respective periods.

ITEM 4.  CONTROLS AND PROCEDURES

     The Company maintains a system of disclosure  controls and procedures.  The
term "disclosure controls and procedures," as defined by regulations of the SEC,
means controls and other procedures that are designed to ensure that information
required to be disclosed in the reports that the Company files or submits to the
SEC under the  Securities  Exchange  Act of 1934,  as amended  (the  "Act"),  is
recorded,  processed,  summarized and reported within the time periods specified
in the SEC's  rules and  forms.  Disclosure  controls  and  procedures  include,
without limitation,  controls and procedures designed to ensure that information
required to be  disclosed by the Company in the reports that it files or submits
to the SEC  under  the Act is  accumulated  and  communicated  to the  Company's
management,   including  its  principal  executive  officer  and  its  principal
financial officer, as appropriate to allow timely decisions to be made regarding
required  disclosure.  Each of Harold C. Simmons,  the Company's Chief Executive
Officer,  and Gregory M.  Swalwell,  the Company's Vice  President,  Finance and
Chief Financial Officer,  have evaluated the Company's  disclosure  controls and
procedures as of June 30, 2004.  Based upon their  evaluation,  these  executive
officers have  concluded that the Company's  disclosure  controls and procedures
are effective as of the date of such evaluation.

     The Company also  maintains a system of internal  controls  over  financial
reporting.  The term "internal control over financial  reporting," as defined by
regulations  of the SEC, means a process  designed by, or under the  supervision
of, the  Company's  principal  executive and principal  financial  officers,  or
persons  performing  similar  functions,  and effected by the Company's board of
directors,  management  and other  personnel,  to provide  reasonable  assurance
regarding  the  reliability  of  financial  reporting  and  the  preparation  of
financial statements for external purposes in accordance with GAAP, and includes
those policies and procedures that:

o    Pertain  to  the  maintenance  of  records  that,  in  reasonable   detail,
     accurately  and fairly reflect the  transactions  and  dispositions  of the
     assets of the Company,
o    Provide reasonable assurance that transactions are recorded as necessary to
     permit  preparation  of financial  statements in accordance  with GAAP, and
     that  receipts  and  expenditures  of the  Company  are being  made only in
     accordance with  authorizations of management and directors of the Company,
     and
o    Provide reasonable  assurance  regarding  prevention or timely detection of
     unauthorized  acquisition,  use or disposition of the Company's assets that
     could  have a  material  effect  on the  Company's  consolidated  financial
     statements.

     There has been no change to the Company's system of internal  controls over
financial  reporting  during the quarter ended June 30, 2004 that has materially
affected,  or is reasonably likely to materially affect, the Company's system of
internal controls over financial reporting.

Item 1.  Legal Proceedings

     Reference is made to Note 14 to the Consolidated Financial Statements,  the
2003  Annual  Report  and the  Company's  Quarterly  Report on Form 10-Q for the
quarter ended March 31, 2004 for  descriptions  of certain  previously  reported
legal proceedings.

     Sabater,  et al. v. Lead Industries  Association,  et al. (Supreme Court of
the State of New York, County of Bronx,  Index No.  25533/98).  In June 2004, at
plaintiffs' request, the trial court dismissed the case with prejudice as to the
adult plaintiffs and without prejudice as to the minor plaintiffs.

     Thomas v. Lead Industries  Association,  et al. (Circuit Court,  Milwaukee,
Wisconsin, Case No. 99-CV-6411).  In June 2004, the appellate court affirmed the
trial court's dismissal of all of plaintiff's  claims.  In July 2004,  plaintiff
filed a petition for review with the Wisconsin Supreme Court.

     State of Rhode  Island v. Lead  Industries  Association,  et al.  (Superior
Court of Rhode Island,  No.  99-5226).  In July 2004,  the Rhode Island  Supreme
Court  dismissed  plaintiff's  appeal  of, and denied  plaintiff's  petition  to
review, the trial court's decision that the case must be tried to a jury.

     Smith,  et al. v. Lead  Industries  Association,  et al. (Circuit Court for
Baltimore City, Maryland, Case No.  24-C-99-004490).  In May 2004, the appellate
court reversed and remanded the trial court's  dismissal of  plaintiffs'  design
defect  claim and other  claims,  but affirmed  the trial  court's  dismissal of
plaintiffs'  fraud  claim and failure to warn  claim.  In July 2004,  plaintiffs
filed a petition for review with the Maryland Court of Appeals.

     City of St. Louis v. Lead Industries Association,  et al. (Missouri Circuit
Court 22nd Judicial  Circuit,  St. Louis City,  Cause No. 002-245,  Division 1).
Defendants'  renewed  motion to dismiss  and motion for  summary  judgment  were
denied by the trial court in March 2004, but the trial court limited plaintiff's
complaint to monetary damages from 1990 to 2000,  specifically  excluding future
damages. In April 2004, the court set a trial date of July 2005.

     Spring Branch Independent  School District v. Lead Industries  Association,
et al. (District Court of Harris County,  Texas, No. 2000-31175).  In June 2004,
the appellate court affirmed the trial court's order granting defendants' motion
for summary judgment. The time for plaintiff's appeal has not run.

     Lewis et al. v. Lead Industries Association,  et al. (Circuit Court of Cook
County, Illinois, County Department,  Chancery Division, Case No. 00CH09800). In
May 2004,  the trial court  denied  defendants'  motion for summary  judgment on
plaintiffs'  conspiracy count. In May 2004,  defendants filed another motion for
summary judgment on plaintiffs' conspiracy count, arguing that plaintiffs cannot
show that all manufacturers of lead pigment were members of a conspiracy.

     Barker, et al. v. The  Sherwin-Williams  Company,  et al. (Circuit Court of
Jefferson County,  Mississippi,  Civil Action No. 2000-587). With respect to the
ten plaintiffs transferred by the trial court to Holmes County, in May 2004, the
Mississippi  Supreme Court remanded the case to the trial court in Holmes County
and instructed the court to transfer the plaintiffs to their appropriate venues.
With respect to the eight plaintiffs remaining in Jefferson County, in July 2004
the  Mississippi  Supreme  Court  denied  plaintiffs'  motion to add  additional
defendants.

     Russell v. NL Industries,  Inc., et al.  (Circuit Court of LeFlore  County,
Mississippi,  No.2002-0235-CICI).  In  May  2004,  four  of the  six  plaintiffs
voluntarily dismissed their claims.

     Jones v. NL  Industries,  Inc., et al.  (Circuit  Court of LeFlore  County,
Mississippi,  Civil Action No.  2002-0241-CICI).  In June 2004,  the court set a
trial date of February 2006.

     The Quapaw Tribe of Oklahoma et al. v. ASARCO  Incorporated  et al. (United
States District Court,  Northern District of Oklahoma,  Case No. 03C-V846 H). In
April 2004, the plaintiffs  filed an amended  complaint  adding claims under the
Resource Conservation Recovery Act ("RCRA") and the Comprehensive  Environmental
Response, Compensation and Liability Act, and the Company moved to dismiss those
claims.  In June 2004,  the trial court  dismissed  the  plaintiffs'  claims for
unjust  enrichment  and fraud as well as one  plaintiff's  claims  arising under
RCRA.

     Evans v.  Asarco  (United  States  District  Court,  Northern  District  of
Oklahoma, Case No. 04-CV-94EA(M)). The trial court has stayed the proceedings in
this case pending the outcome of a class certification  decision in Cole, et al.
v. ASARCO  Incorporated et al. (U.S. District Court for the Northern District of
Oklahoma,  Case No.  03C V327 EA (J))  case,  from  which the  Company  has been
dismissed with prejudice.
