FOR IMMEDIATE RELEASE
                        NL REPORTS FOURTH QUARTER RESULTS

DALLAS, TEXAS -February 24, 2004 -- NL Industries, Inc. (NYSE:NL) today reported
net income for the fourth  quarter of 2003 of $8.8 million,  or $.18 per diluted
share,  compared with income of $7.6 million,  or $.16 per diluted share, in the
fourth  quarter of 2002. For the full year 2003, NL reported net income of $63.7
million, or $1.33 per diluted share,  compared with net income of $36.8 million,
or $.76 per diluted share, for the full year 2002.

The Company's  titanium  dioxide  pigments  ("TiO2")  segment  profit  (formerly
referred  to as  "operating  income")  in the  fourth  quarter of 2003 was $32.2
million  compared with $20.1 million in the fourth quarter of 2002. The increase
in fourth  quarter  segment  profit was primarily due to higher  production  and
sales volumes and lower maintenance costs. Segment profit for the full year 2003
increased  to $137.4  million  compared  with $96.5  million for full year 2002,
primarily due to higher average selling prices and higher production volumes.

The Company's  average selling prices in billing  currencies (which excludes the
effects  of  fluctuations  in the  value of the U.S.  dollar  relative  to other
currencies)  during  the  fourth  quarter  of 2003 were 2% lower than the fourth
quarter  of 2002,  due  primarily  to sales to the  North  American  and  export
markets,  but were 3% higher for the full year 2003  compared to 2002  primarily
due to sales to the European  market.  Expressed in U.S.  dollars computed using
actual foreign currency exchange rates prevailing during the respective periods,
the  Company's  average  selling  prices in the  fourth  quarter of 2003 were 8%
higher  than the fourth  quarter of 2002,  and were 13% higher for the full year
2003 compared with 2002.

The Company's  fourth  quarter 2003 sales  volumes  increased 9% from the fourth
quarter of 2002,  with  substantially  all of the  increase in the  European and
export  markets.  Sales  volumes  for  the  full  year  2003  set a new  record,
increasing 2% from the previous  record  achieved in 2002. The Company's  fourth
quarter 2003 production volumes were 14% higher than the fourth quarter of 2002,
and were 8% higher for the full year 2003 compared to 2002, with operating rates
at near full capacity in all periods presented.  The Company's production volume
also set a new record in 2003.  Inventories  were higher at December 31, 2003 as
compared to December 31, 2002, and represented 2.2 months of average sales.

Certain of the sales generated by the Company's European and Canadian operations
are  denominated in the U.S.  dollar,  and such  operations  routinely hold U.S.
dollar-denominated  receivables.  Primarily as a result of the  weakening of the
U.S. dollar as compared to the Canadian dollar and the euro throughout the year,
the  Company's  results in the fourth  quarter and full year 2003  included  net
currency transaction losses of $3.4 million and $7.7 million,  respectively. Due
to a more stable dollar in 2002, the Company recognized net currency transaction
gains of $300,000  in the fourth  quarter of 2002 and net  currency  transaction
losses of $500,000 for the full year.

Securities gains (losses), net for 2003 included the  previously-reported  first
quarter $2.3 million noncash securities  transaction gain ($1.5 million, or $.03
per diluted share, net of income taxes) related to the exchange of the Company's
holdings of Tremont  Corporation  common stock for shares of Valhi,  Inc. common
stock as a result of a series of merger transactions completed in February 2003.
Interest income in 2003 was lower than 2002 due to lower average levels of funds
available for investment.

The gain on disposal of fixed assets in 2003  related  primarily to the disposal
of certain real property not associated with the Company's TiO2 operations,  and
aggregated $6.7 million,  or $.14 per diluted share, net of income taxes for the
year ($1.2 million,  or $.02 per diluted share, for the fourth quarter of 2003).
The legal  settlement  gains in both 2002 and 2003  relate to legal  settlements
with certain of the Company's former insurance  carriers,  which aggregated $3.4
million,  or $.07 per diluted share,  net of income taxes in 2002 ($1.9 million,
or  $.04  per   diluted   share,   in  the   fourth   quarter   of  2002).   The
previously-reported  $6.3 million  foreign  currency  transaction  gain in 2002,
which  aggregated  $.13  per  diluted  share,  related  to  the  second  quarter
extinguishment of certain intercompany  indebtedness.  Due to the utilization of
certain income tax attributes  not previously  recognized,  no income taxes were
recognized on this foreign  currency  transaction  gain in 2002.  The noncompete
agreement income related to a covenant not to compete involving a formerly owned
business unit which became fully amortized in January 2003.

Corporate  expense for 2003  increased  compared to 2002 primarily due to higher
environmental  remediation expense accruals (principally related to one formerly
owned site for which the remediation  process is expected to occur over the next
several years) and higher legal expenses.

Interest expense in the fourth quarter and full year 2003 increased $700,000 and
$3.3 million,  respectively,  from the comparable 2002 periods  primarily due to
higher levels of outstanding  debt and associated  currency  effects,  partially
offset by lower interest rates. As previously reported, interest expense in 2002
includes a second quarter $2.0 million charge ($1.3 million, or $.03 per diluted
share,  net of income tax benefit)  related to the early  extinguishment  of the
Company's 11.75% Senior Secured Notes.

The Company's income tax benefit for 2003 includes the previously-reported $24.6
million  cash  income  tax  benefit  ($.51 per  diluted  share)  related  to the
favorable German court ruling concerning the Company's claim for refund suit.

In an effort to provide  investors  with  additional  information  regarding the
Company's results as determined by accounting  principles  generally accepted in
the  United  States of America  ("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 its 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 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.  o The Company  discloses
     segment profit (formerly referred to as "operating income"). Segment profit
     is used by the  Company's  management  to  assess  the  performance  of the
     Company's  TiO2  operations.  The Company  believes  disclosure  of segment
     profit provides useful information to investors because it allows investors
     to analyze the performance of the Company's TiO2 operations in the same way
     that the Company's  management  assesses  performance.  The Company defines
     segment profit as income before income taxes,  minority interest,  interest
     expense and certain general corporate items.  Corporate items excluded from
     the  determination of segment profit include  corporate  expense,  interest
     income  not  attributable  to the  Company's  TiO2  operations,  litigation
     settlement  gains,  securities  gains  (losses),  gains on the  disposal of
     long-lived  assets  outside the ordinary  course of business or  long-lived
     assets not  associated  with the Company's  TiO2  operations and noncompete
     agreement income

NL Industries,  Inc.,  through its  majority-owned  subsidiary  Kronos Worldwide
Inc., is a major international producer of titanium dioxide pigments.


The statements in this release 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," "will," "should," "could," "anticipates," "expects," or comparable terminology or by discussions of strategy 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.
