FOR IMMEDIATE RELEASE
                        NL REPORTS FIRST QUARTER RESULTS

DALLAS,  TEXAS...May 5, 2004...NL Industries,  Inc. (NYSE:NL) today reported net
income for the first quarter of 2004 of $4.1 million, or $.08 per diluted share,
compared with income of $9.4 million,  or $.20 per diluted  share,  in the first
quarter of 2003.

The Company conducts its titanium dioxide pigments ("TiO2") business through its
majority-owned  subsidiary,  Kronos  Worldwide,  Inc.  Kronos'  sales of  $263.3
million in the first quarter of 2004 were $10.3 million,  or 4%, higher than the
first  quarter  of 2003 as the  favorable  effect  of  fluctuations  in  foreign
currency  exchange rates,  which increased sales by  approximately  $21 million,
more than offset the impact of lower average  selling  prices for TiO2.  Despite
the  increase  in sales,  TiO2  segment  profit  (see  description  of  non-GAAP
information  below)  declined  to $26.2  million  in the first  quarter  of 2004
compared  with $34.4 million in the first quarter of 2003 due primarily to lower
average TiO2 selling prices.

Kronos' 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 first  quarter of 2004 were 4% lower than the first  quarter of 2003.
Expressed in U.S. dollars computed using actual foreign currency  exchange rates
prevailing during the respective periods,  Kronos' average selling prices in the
first quarter of 2004 were 4% higher than the first quarter of 2003.

Kronos's  TiO2  sales  and  production  volumes  in the  first  quarter  of 2004
approximated its respective sales and production volumes in the first quarter of
2003, with operating rates at near full capacity in both periods. Finished goods
inventories at March 31, 2004,  which  represented  2.2 months of average sales,
were lower as compared to December 31, 2003.

Corporate  expense for 2004  decreased  compared to 2003  primarily due to lower
environmental remediation and legal expenses.

Securities  transactions,  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  expense in the first quarter of 2004  increased  $1.2 million from the
comparable 2003 period,  primarily due to relative  changes in foreign  currency
exchange rates,  which increased the U.S. dollar  equivalent of interest expense
on Kronos International's euro-denominated Senior Secured Notes by approximately
$1.1  million in the first  quarter of 2004 as compared to the first  quarter of
2003.

The Company's  effective  income tax rate in the first quarter of 2004 was lower
than the first  quarter  of 2003 due  primarily  to the  utilization  of certain
income tax attributes for which the benefit had not previously been recognized.

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.  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 include, but are not limited to: o Future supply and demand for the Company's products, o The cyclicality of certain of the Company's businesses, o Customer inventory levels, o Changes in raw material and other operating costs, o The possibility of labor disruptions, o General global economic and political conditions, 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, o Operating 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 controversies, o Environmental matters, o Government laws and regulations and possible changes therein, o The ultimate resolution of pending litigation, 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. 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 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 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 TiO2 operations of Kronos. The Company believes disclosure of segment profit provides useful information to investors because it allows investors to analyze the performance of the 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 TiO2 operations, securities gains (losses) and noncompete agreement income. NL Industries, Inc., through its majority-owned subsidiary Kronos Worldwide Inc., is a major international producer of titanium dioxide pigments.
