                     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 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.  At  September  30, 1998 Valhi,  Inc.  and Tremont  Corporation,  each
affiliates of Contran Corporation, held approximately 58% and 19%, respectively,
of NL's  outstanding  common stock, and together may be deemed to control NL. At
September  30,  1998  Contran and its  subsidiaries  held  approximately  92% of
Valhi's outstanding common stock, and Valhi and other entities related to Harold
C. Simmons held approximately 53% of Tremont's outstanding common stock.

      The  consolidated  balance sheet of NL Industries,  Inc. and  Subsidiaries
(collectively,  the  "Company") at December 31, 1997 has been condensed from the
Company's  audited   consolidated   financial   statements  at  that  date.  The
consolidated balance sheet at September 30, 1998 and the consolidated statements
of income,  comprehensive  income,  shareholders'  equity and cash flows for the
interim  periods  ended  September  30, 1997 and 1998 have been  prepared by the
Company,  without  audit.  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  and  footnote   disclosures   normally  included  in
financial  statements  prepared in accordance with generally accepted accounting
principles have been condensed or omitted.  Certain prior-year amounts have been
reclassified to conform to the current year  presentation,  including  reporting
the Company's  specialty  chemicals  business as a discontinued  operation.  The
accompanying  consolidated  financial  statements  should be read in conjunction
with the  consolidated  financial  statements  included in the Company's  Annual
Report on Form 10-K for the year  ended  December  31,  1997 (the  "1997  Annual
Report").

      The  Company  will  adopt  Statement  of  Financial  Accounting  Standards
("SFAS") No. 133, Accounting for Derivative  Instruments and Hedging Activities,
no later than the first  quarter of 2000.  SFAS No. 133  establishes  accounting
standards for derivative  instruments,  including certain derivative instruments
embedded in other contracts, and for hedging activities. Under SFAS No. 133, all
derivatives  will be recognized as either assets or liabilities  and measured at
fair value.  The accounting for changes in fair value of derivatives will depend
upon the intended use of the derivative.  The Company is currently studying this
newly-issued  accounting  rule, and the impact of adopting SFAS No. 133, if any,
has not yet been  determined  but will be dependent upon the extent to which the
Company  is  then  a  party  to  derivative  contracts  or  engaged  in  hedging
activities.  At September 30, 1998 the Company is not a party to any  derivative
contracts or engaged in any hedging activities covered by SFAS No. 133.

                                   - 11 -





NOTE 2 - EARNINGS PER SHARE:

      Basic  earnings  per  share are based on the  weighted  average  number of
common shares  outstanding  during each period.  Diluted  earnings per share are
based on the weighted average common shares  outstanding and the dilutive impact
of outstanding stock options.

NOTE 3 - BUSINESS SEGMENT INFORMATION:

      The  Company's  continuing  operations  are  conducted  by  Kronos  in one
business segment - TiO2.

NOTE 13 - DISCONTINUED OPERATIONS:

      The Company sold the net assets of its Rheox specialty  chemicals business
for $465 million cash (before fees and  expenses) in the first  quarter of 1998,
including $20 million  attributable to a five-year  agreement by the Company not
to compete in the  rheological  products  business.  The Company  recognized  an
after-tax  gain of  approximately  $286  million  on the  sale of this  business
segment.  A portion of the $380  million  after-tax  proceeds was used to reduce
outstanding indebtedness by approximately $231 million.

      Condensed income statement data related to discontinued operations for the
interim  periods  ended  September  30, 1997 and 1998 are as  follows.  Interest
expense has been  allocated to  discontinued  operations  based on the amount of
debt specifically attributed to Rheox's operations.

NOTE 14 - COMMITMENTS AND CONTINGENCIES:

      For  descriptions  of  certain  legal  proceedings,  income  tax and other
commitments and contingencies  related to the Company,  reference is made to (i)
Management's  Discussion  and  Analysis of  Financial  Condition  and Results of
Operations,  (ii) Part II,  Item 1  -"Legal  Proceedings,"  (iii) the  Company's
Quarterly Report on Form 10-Q for the quarters ended March 31, 1998 and June 30,
1998, and (iv) the 1997 Annual Report.



                                   - 16 -





      In July 1998 the Company reached an agreement (the "Tioxide  Purchase") to
(i) acquire the North American TiO2 operations of Imperial  Chemical  Industries
plc's ("ICI")  subsidiary,  Tioxide Group  Limited,  and a Tioxide TiO2 plant in
England, and (ii) cancel certain rights to chloride-process  technology licensed
to Tioxide by the Company in connection with the formation of Louisiana  Pigment
Company ("LPC") in 1993. The aggregate amount to be paid to ICI is approximately
$365  million,  including a $30 million fee for the  cancellation  of technology
rights and approximately $50 million in working capital. The purchase is subject
to regulatory clearances,  completion of the purchase by E.I. du Pont de Nemours
&  Co.  of  ICI's  remaining  non-North  American  TiO2  business  (the  "DuPont
Purchase"), and other conditions customary to transactions of this type.

      The operations to be acquired  include  Tioxide's  50%-interest  in LPC, a
manufacturing  joint  venture  of  the  Company  and  Tioxide  that  operates  a
chloride-process  TiO2 plant in Louisiana with capacity of approximately 120,000
metric tons per annum ("mtpa"); Tioxide's 75,000 mtpa sulfate-process TiO2 plant
in Grimsby, England; Tioxide's 52,000 mtpa finishing plant in Tracy, Quebec; and
Tioxide's North American marketing and distribution business.

      Upon  completion  of the DuPont  Purchase  and the Tioxide  Purchase,  the
Company  expects to become  the  world's  third  largest  manufacturer  of TiO2,
increasing its productive capacity by approximately 135,000 mtpa.

      Assuming  regulatory  clearances are received in 1998, the Company expects
the Tioxide Purchase to close in the first quarter of 1999.

      Kronos'  operating  income in the third  quarter  and first nine months of
1998 increased from the comparable periods in 1997 due to higher average selling
prices,  partially  offset by lower sales volume and the absence of $9.7 million
of income from refunds of German  franchise  taxes received in the third quarter
of 1997. Kronos expects its fourth-quarter 1998 operating income will exceed its
fourth-quarter  1997  operating  income  primarily  because  of  higher  average
fourth-quarter  1998 TiO2 selling prices,  partially  offset by moderately lower
fourth-quarter 1998 sales volume.

      Average TiO2 selling  prices for the third quarter of 1998 were 17% higher
than the third quarter of 1997 and 2% higher than the second quarter of 1998.

      Kronos'  third-quarter  sales  volume  decreased  9% from the record sales
volume in the year-earlier period as demand moderated. Sales volume in the first
nine  months  of 1998  was 2%  lower  than  the  year-earlier  period  primarily
reflecting  lower sales volume in Asia,  partially offset by higher sales volume
in  Europe.  As a result of lower  second-half  1998  demand  for  TiO2,  Kronos
anticipates its TiO2 sales volume for full-year 1998 will be slightly below that
of calendar year 1997.

      Kronos' cost of sales as a percentage of net sales  decreased in the third
quarter and first nine months of 1998  primarily due to higher  average  selling
prices.  Kronos' selling,  general and administrative  expenses decreased in the
third  quarter  and first nine  months of 1998 due to lower  distribution  costs
associated  with lower sales volume and  favorable  effects of foreign  currency
translation,  partially offset by the impact of the German franchise tax refunds
received in the third quarter of 1997.

      A significant amount of sales are denominated in currencies other than the
U.S. dollar,  and fluctuations in the value of the U.S. dollar relative to other
currencies  decreased  the dollar value of sales for the third quarter and first
nine months of 1998 by $3 million and $26 million, respectively, compared to the
comparable 1997 periods.

      Securities earnings increased due to higher average balances available for
investment.  Corporate expenses,  net in the first nine months of 1998 was lower
than the comparable  period in 1997 due to the $30 million  noncash charge taken
in the first quarter of 1997 related to the Company's  adoption of SOP No. 96-1,
"Environmental  Remediation  Liabilities."  This  charge is included in selling,
general and administrative expense in the Company's  consolidated  statements of
income.

      The Company expects general corporate interest income and interest expense
to be lower in the fourth  quarter of 1998 compared to the third quarter of 1998
due to the  redemption  of the remaining 13% Senior  Secured  Discount  Notes on
October 15, 1998.

      Income  taxes in the third  quarter of 1998  include a tax benefit of $8.2
million resulting from a refund of prior-year German dividend withholding taxes.

      The Company sold the net assets of its Rheox specialty  chemicals business
in the first quarter of 1998 and, as a result of the sale,  Rheox's  results are
reported as discontinued operations.

      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, before changes in assets and liabilities,

                                   - 19 -





in the 1998 period improved significantly from the comparable period in 1997 due
to higher operating income.  Changes in the Company's  inventories,  receivables
and payables  (excluding  the effect of currency  translation)  used cash in the
first nine  months of 1998 but  provided  cash in the first nine  months of 1997
primarily due to  reductions  in inventory  levels in the 1997 period and higher
payments  of income  taxes in the 1998 period as a result of the gain on sale of
Rheox.

      The  sale of the  Company's  specialty  chemicals  business  in the  first
quarter of 1998 resulted in net proceeds of $380 million  after  current  income
taxes and other  expenses.  In the first nine months of 1998, the Company used a
portion of the net proceeds to repay certain  indebtedness,  as described below,
and on  October  15,  1998,  used a portion  of the net  proceeds  to redeem the
remaining  $119 million of 13% Senior  Secured  Discount Notes at the redemption
price of 106% of the  principal  amount,  in  accordance  with the  terms of the
Discount Notes indenture.

      During the first nine months of 1998,  the  Company  used a portion of the
net  proceeds  to (i) prepay $118  million of the Rheox  credit  facility,  (ii)
prepay $42 million of Kronos'  share of the LPC joint  venture term loan,  (iii)
make $65 million of  open-market  purchases of the Company's 13% Senior  Secured
Discount  Notes at prices  ranging  from  $101.25 to  $105.19  per $100 of their
principal amounts,  and (iv) purchase $6 million of the Senior Secured Notes and
$61 thousand of the Senior Secured  Discount Notes at a price of $100 and $96.03
per $100 of their principal amounts,  respectively,  pursuant to a June 1998 pro
rata tender offer to Note holders as required under the terms of the indenture.

      The Company  prepaid DM 81 million  ($44 million when paid) of its DM term
loan in the first quarter of 1998. A portion of the funds for such prepayment of
the DM term loan was provided by a first-quarter DM 35 million ($19 million when
borrowed)  increase in  outstanding  borrowings  under the Company's  short-term
non-U.S. credit facilities. In the second quarter of 1998, the Company repaid DM
20 million ($11 million when paid) of the DM revolving credit facility.

      In order to complete the Tioxide  Purchase,  the Company expects to borrow
approximately $250 million in bank financing.

      At  September  30,  1998  the  Company  had  cash  and  cash   equivalents
aggregating  $321  million  (14%  held  by  non-U.S.  subsidiaries),   including
restricted cash equivalents of $13 million.  The Company's  subsidiaries had $91
million  available for borrowing at September 30, 1998 under  existing  non-U.S.
credit facilities.

      In the  third  quarter  of 1998,  the  Company  paid a  regular  quarterly
dividend of $.03 per share to shareholders  aggregating $1.5 million.  Dividends
paid during the first nine months of 1998 totaled $3.1 million.  In October 1998
the Company's Board of Directors  declared a regular quarterly  dividend of $.03
per  share to  shareholders  of  record as of  December  16,  1998 to be paid on
December 30, 1998.

      In June 1998, as a result of the  settlement  of a shareholder  derivative
lawsuit on behalf of the Company, Valhi transferred $14.4 million in cash to the

                                   - 20 -





Company, and the Company agreed to pay plaintiffs'  attorneys' fees and expenses
of $3.2 million.

      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,  including  non-income tax related items and interest.
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. In the third quarter of 1998,  the Company  received a DM 14
million ($8.2 million when received) refund of 1990 German dividend  withholding
taxes.  The German tax authorities were required to refund such amounts based on
a recent German Supreme Court decision in favor of another taxpayer.  The refund
resulted in a reduction of the settlement  amount from DM 44 million referred to
above to DM 30  million  for years  through  1990.  No further  withholding  tax
refunds are expected.

      Certain  other  significant   German  tax  contingencies   aggregating  an
estimated  DM 172 million  ($102  million at September  30,  1998)  through 1997
remain outstanding and are in litigation. Of these, one primary issue represents
disputed amounts  aggregating DM 160 million ($95 million at September 30, 1998)
for  years  through  1997.  The  Company  has  received  tax  assessments  for a
substantial   portion  of  these  amounts.   No  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 this issue was decided in favor of the taxpayer.  The
German tax authorities  have appealed that decision to the German Supreme Court.
The  Company  believes  that a  decision  by the  German  Supreme  Court will be
rendered  within a year and will likely  determine  the outcome of the Company's
primary dispute with the German tax  authorities.  Although the Company believes
that it will ultimately  prevail in this matter, the Company has granted a DM 94
million ($56 million at September 30, 1998) lien on its Nordenham,  Germany TiO2
plant in favor of the City of  Leverkusen,  and a DM 5 million  ($3  million  at
September 30, 1998) lien in favor of the German federal tax authorities.  If the
Company does not prevail,  these  contingencies  will increase the Company's tax
liability  for 1990 and each year  thereafter,  and the  Company  would  seek to
negotiate payment over a period of time.

      In addition,  during 1997 the Company reached an agreement with the German
tax authorities  regarding  certain other issues not in litigation for the years
1991 through 1994, and agreed to pay additional tax deficiencies of DM 9 million
($5 million at September 30, 1998),  most of which was paid in the third quarter
of 1998.

      During 1997 the Company  received a tax assessment  from the Norwegian tax
authorities  proposing  tax  deficiencies  of  NOK 51  million  ($7  million  at
September 30, 1998) relating to 1994.  The Company has appealed this  assessment
and has begun litigation proceedings. Although the Company believes that it will
ultimately  prevail,  the  Company has granted a lien for the full amount of the
tax assessment on its  Fredrikstad,  Norway TiO2 plant in favor of the Norwegian
tax authorities.

      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 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  the  Company's
consolidated financial position, results of operations or liquidity.

      The Company has been named as a defendant,  potentially  responsible party
("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.  Environmental  Protection  Agency's (the "U.S.  EPA") 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
($128  million at September  30, 1998) for  reasonably  estimable  costs of such
matters,  but the  Company's  ultimate  liability may be affected by a number of
factors,   including  changes  in  remedial  alternatives  and  costs,  and  the
allocations  of such costs among PRPs.  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 $160 million. The Company's estimates of such liabilities have not
been  discounted  to present  value,  and the  Company  has not  recognized  any
potential insurance recoveries. 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.

      The Company is also a defendant in a number of legal  proceedings  seeking
damages for personal  injury and property  damage  arising from 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 be reasonably
estimated. In addition, various legislation and administrative regulations have,
from  time to time,  been  enacted  or  proposed  that  seek to  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 to effectively  overturn  court  decisions in which the Company and
other  pigment  manufacturers  have been  successful.  Examples of such proposed
legislation  include bills which would permit civil liability for damages on the
basis of market  share,  rather  than  requiring  plaintiffs  to prove  that the
defendant's  product caused the alleged damage.  The Company currently  believes
the disposition of all claims and disputes,  individually  and in the aggregate,
should  not  have  a  material  adverse  effect  on the  Company's  consolidated
financial

                                   - 22 -





position,  results of operations or  liquidity.  There can be no assurance  that
additional matters of these types will not arise in the future.

      The Company is in the process of  evaluating  and  upgrading  its computer
systems (both information technology ("IT") systems and non-IT systems involving
embedded chip technology) and software applications (collectively referred to as
"systems") to ensure that the systems  function  properly  beginning  January 1,
2000.  To achieve  its year 2000  compliance  plan,  the  Company  is  utilizing
internal and external resources to identify,  correct or reprogram, and test its
systems.

      The Company has conducted an inventory of its IT systems  worldwide and is
currently  testing the  systems and  applications  that have been  corrected  or
reprogrammed for year 2000  compliance.  The Company has completed a preliminary
inventory  of its  non-IT  systems  and  is in the  process  of  validating  the
inventory and correcting or replacing date-deficient systems. The Company uses a
number of  packaged  software  products  that have been  upgraded to a year 2000
compliant version in the normal course of business.  Excluding the cost of these
software  upgrades,  the  Company's  cost of  becoming  year 2000  compliant  is
expected to be approximately $2 million, of which about one-third has been spent
through September 1998. The Company expects its major IT systems to be year 2000
compliant  by March  1999,  and  expects  its  non-IT  systems  to be year  2000
compliant by September 1999.

      As part of its year  2000  compliance  plan,  the  Company  has  requested
confirmations  from its major domestic and foreign  software  vendors,  hardware
vendors and primary  suppliers,  that they are developing and implementing plans
to become, or are, year 2000 compliant.  Confirmations received to date from the
Company's software vendors, hardware vendors and primary suppliers indicate that
generally they are in the process of  implementing  remediation  plans to ensure
that their  systems are  compliant  by December  31,  1999.  The major  software
vendors used by the Company have already delivered year 2000 compliant software.
The Company plans to request  confirmations  from its major  customers that they
are developing or implementing plans to become year-2000 compliant.

      The Company is developing a  contingency  plan to address  potential  year
2000  related  business  interruptions  that may occur on January  1,  2000,  or
thereafter. This plan is expected to be completed in the second quarter of 1999.

      Although the Company expects its systems to be year 2000 compliant  before
December  31,  1999,  it cannot  predict the outcome or success of the year 2000
compliance programs of its vendors,  suppliers,  and customers. The Company also
cannot predict whether its major software vendors, who continue to test for year
2000  compliance,  will find additional  problems that would result in unplanned
upgrades of their  applications  after  December 31, 1999.  As a result of these
uncertainties,  the Company cannot predict the impact on its financial condition
or results of  noncompliant  year 2000  systems  that the  Company  directly  or
indirectly  relies upon.  Should the Company's year 2000  compliance plan not be
successful or be delayed beyond January 2000,  the  consequences  to the Company
could be  far-reaching  and material,  including an inability to produce TiO2 at
its  manufacturing  facilities,  which could lead to an indeterminate  amount of
lost

                                   - 23 -





revenue.  Other potential negative consequences could include plant malfunction,
impeded  communications or power supplies, or slower transaction  processing and
financial reporting.

      Beginning  January 1, 1999,  eleven of the fifteen members of the European
Union ("EU"),  including  Germany,  Belgium,  the Netherlands  and France,  have
agreed to adopt a new European  currency unit (the "euro") as their common legal
currency.  Following the introduction of the euro, the participating  countries'
national  currencies will remain legal tender as  denominations of the euro from
January 1, 1999 through January 1, 2002, and the exchange rates between the euro
and such national currency units will be fixed.

      The Company  conducts  substantial  operations in Europe.  The  functional
currency of the Company's  German,  Belgian,  Dutch and French  operations  will
convert to the euro from their  respective  national  currencies over a two-year
period  beginning  in  1999.  The  euro  conversion  may  impact  the  Company's
operations including,  among other things,  changes in product pricing decisions
necessitated  by  cross-border  price  transparencies.  Such  changes in product
pricing  decisions  could impact both selling prices and  purchasing  costs and,
consequently, favorably or unfavorably impact results of operations.

      The  Company  has  a  significant  amount  of  outstanding  DM-denominated
indebtedness  and such debt will become  euro-denominated  effective  January 1,
1999.   Modifications   of  information   systems  to  handle   euro-denominated
transactions will be required, although the modifications are not expected to be
extensive.

      The Company has begun to assess and evaluate  the  expected  impact of the
euro conversion on its business.  Such  evaluations are still in process but are
expected to be  concluded by the end of 1998.  The Company  expects to spend and
charge to expense  less than $1  million in  evaluation  and  conversion  costs.
Because  of  the  inherent  uncertainty  of the  ultimate  affect  of  the  euro
conversion,  the Company cannot accurately  predict the impact on its results of
operations, financial condition or liquidity.

      The Company periodically evaluates its liquidity requirements, alternative
uses of capital,  capital needs and  availability of resources in view of, among
other  things,  its  debt  service  and  capital  expenditure  requirements  and
estimated future operating cash flows. As a result of this process,  the Company
in the past has  sought,  and in the  future  may seek,  to  reduce,  refinance,
repurchase  or  restructure   indebtedness,   raise  additional  capital,  issue
additional  securities,   modify  its  dividend  policy,  restructure  ownership
interests, sell interests in subsidiaries or other assets, or take a combination
of such steps or other steps to manage its liquidity and capital  resources.  In
the normal course of its business,  the Company may review opportunities for the
acquisition,  divestiture,  joint venture or other business  combinations in the
chemicals   industry.   In  the  event  of  any  acquisition  or  joint  venture
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.
