FOR IMMEDIATE RELEASE

                        NL REPORTS FOURTH QUARTER RESULTS

HOUSTON,  TEXAS -  January  31,  2003 -- NL  Industries,  Inc.  (NYSE:NL)  today
reported  net income for the fourth  quarter of 2002 of $.16 per  diluted  share
compared  with $.83 per diluted share in the fourth  quarter of 2001.  Excluding
the effect of the items summarized in the accompanying  table, net income in the
fourth quarter of 2001 was $.12 per diluted share.

Net income for  full-year  2002 was $.76 per  diluted  share  compared  with net
income for full-year  2001 of $2.44 per diluted  share.  Excluding the effect of
the items  summarized in the  accompanying  table, net income for full-year 2002
was $.64 per diluted  share  compared with $1.72 per diluted share for full-year
2001.

The Company's  titanium dioxide pigments ("TiO2") operating income in the fourth
quarter of 2002 was $20.1  million  compared  with  $35.9  million in the fourth
quarter of 2001.  Operating  income in the fourth quarter of 2001 included $16.6
million  of  business   interruption   insurance   proceeds  related  to  losses
(unallocated  period  costs and lost  margin)  incurred  in prior 2001  quarters
resulting from the previously reported fire at the Company's Leverkusen, Germany
plant in March  2001.  Excluding  this  amount,  operating  income in the fourth
quarter of 2002  increased 4% compared with the fourth quarter of 2001 primarily
due to higher sales and  production  volumes  partially  offset by higher costs.
Compared with the third quarter of 2002,  operating income in the fourth quarter
of  2002  decreased  $9.5  million  or 32%  primarily  due to  lower  sales  and
production volumes,  and higher costs partially offset by higher average selling
prices.

Operating  income for  full-year  2002 was $96.5  million  compared  with $169.2
million for full-year  2001 due to 9% lower average  selling  prices,  partially
offset by 13% higher sales  volume and 7% higher  production  volume.  Operating
income for  full-year  2001  included  $27.3  million of  business  interruption
insurance  proceeds  related  to  the  Leverkusen  fire.  The  lower  sales  and
production  volumes  in 2001 were due in part to the  effect  of the  Leverkusen
fire.

The Company's  average selling price in billing  currencies  (which excludes the
effects of foreign currency  translation)  during the fourth quarter of 2002 was
comparable  to the  fourth  quarter  of 2001 and was 2%  higher  than the  third
quarter of 2002.  Compared  with the third  quarter of 2002,  selling  prices in
billing currencies  increased in all major markets. The average selling price in
billing currencies in December 2002 was 1% higher than the average selling price
for the fourth quarter.

The  Company's  fourth  quarter 2002  average  selling  price  expressed in U.S.
dollars (computed using actual foreign currency exchange rates prevailing during
the  respective  periods)  was 4% higher than the fourth  quarter of 2001 and 2%
higher than the third quarter of 2002.  The average  selling price  expressed in
U.S.  dollars in December 2002 was 1% higher than the average  selling price for
the fourth  quarter.  The average  selling price  expressed in U.S.  dollars for
full-year 2002 was 7% lower than full-year 2001.

The  Company's  fourth  quarter 2002 sales volume  increased 12% from the fourth
quarter of 2001 and decreased  13% from the third quarter of 2002.  The increase


                                   Page 1 of 5

from the comparable prior year period was due in part to lost sales volume in 2001 as a result of the Leverkusen fire. Finished goods inventory levels at the end of the fourth quarter increased 6% from September 2002 levels and represented approximately two months of sales. The Company's fourth quarter 2002 production volume was 11% higher than the fourth quarter of 2001 and decreased 8% from the third quarter of 2002 with operating rates at 90% in the fourth quarter of 2002 compared with 83% in the fourth quarter of 2001. Decreased production volume in the fourth quarter of 2002 was primarily due to maintenance stops. Full-year operating rates were at 96% in 2002 compared with 91% in 2001. The full-year 2001 lower operating rates were partly due to the effect of the Leverkusen fire. J. Landis Martin, President and Chief Executive Officer, stated, "This year's sales volume of 455,000 metric tons was a Company record and was supported by a Company record 442,000 metric tons of production. TiO2 prices continue to trend upward and we, and other major TiO2 producers, have recently announced a new round of price increases. We started 2003 with higher selling prices as compared to last year, with prices trending upward, not downward as they were at the start of 2002. We expect full-year 2003 sales volume to be comparable to last year and full-year 2003 average selling prices to be higher than 2002. Based on these assumptions, we expect to report higher operating income in 2003 versus 2002. However, it is difficult to predict full-year 2003 results due to uncertainties surrounding the economy, including the potential for international conflict." Securities earnings for the fourth quarter and full-year 2002 decreased $.4 million and $2.2 million, respectively, from the comparable periods in 2001, primarily due to lower average interest yields on invested funds in 2002. Corporate income for the fourth quarter of 2002 included a $2.9 million litigation settlement gain with former insurance carrier groups. Corporate income for full-year 2002 decreased $7.0 million from full-year 2001 primarily due to lower litigation settlement gains. During the fourth quarter of 2002, the Company commenced accounting for its stock options using the variable accounting method, which requires the intrinsic value of the stock option to be accrued as an expense. The Company recognized $3.2 million of compensation expense in the fourth quarter of 2002 related to its stock options, of which $1.6 million was charged to operating income and $1.6 million was charged to general corporate expenses. Corporate expense for the fourth quarter of 2002 increased $1.9 million compared with the fourth quarter of 2001 primarily due to higher legal expenses and stock option compensation expense, partially offset by lower environmental expenses. Compared to the third quarter of 2002, corporate expense in the fourth quarter of 2002 decreased $.9 million primarily due to lower legal and environmental expenses partially offset by stock option compensation expense. Full-year 2002 corporate expense increased $11.9 million from full-year 2001 primarily due to higher legal and stock option compensation expenses. Interest expense in the fourth quarter of 2002 increased $.8 million from the fourth quarter of 2001 primarily due to higher levels of outstanding debt, partially offset by lower interest rates. Interest expense for full-year 2002 increased $2.2 million from full-year 2001 primarily due to additional second-quarter 2002 interest expense related to the early extinguishment of debt. The Company's income tax provision in the fourth quarter of 2002 included a $2.3 million deferred income tax benefit related to the enactment of certain income tax law changes in Belgium. Minority interest primarily related to the Company's majority-owned environmental management subsidiary. The Company's net debt at December 31, 2002 was $195.5 million, up $130.9 million from September 30, 2002. The increase in net debt during the fourth quarter of 2002 primarily related to the $2.50 per share additional shareholder dividend totaling $119.2 million. Net debt at December 31, 2002 was comprised of total debt of $325.9 million less cash, restricted cash and restricted marketable debt securities of $130.4 million. Page 2 of 5
