NL REPORTS FOURTH QUARTER RESULTS

DALLAS, TEXAS – March 12, 2008 - NL Industries, Inc. (NYSE:NL) today reported  net income of $10 million, or $.21 per diluted share, in the fourth quarter of 2007 compared to net income of $13.6 million, or $.28 per diluted share, in the fourth quarter of 2006.  For the full year 2007, NL reported a net loss of $1.7 million, or $.04 per diluted share, compared to net income of $26.1 million, or $.54 per diluted share, for 2006.

Component products sales decreased 4% in the fourth quarter of 2007 as compared to the fourth quarter of 2006, and decreased 7% in 2007 compared to 2006.  The decreases were primarily due to lower sales of certain products to the office furniture market where Asian competitors have established selling prices at a level below which CompX considers would return a minimal margin as well as lower order rates from many customers due to general economic conditions, offset in part by the effect of sales price increases for certain products to mitigate the effect of higher raw material costs.  Component products income from operations decreased 66% in the fourth quarter 2007 compared to the fourth quarter 2006 and decreased 25% in 2007 compared to 2006 as the unfavorable effects of lower sales volume, higher raw material costs and approximately $2.7 million of facility consolidation expenses more than offset the favorable effects of a change in product mix and our ongoing focus on reducing costs and improving efficiency.  Component products income from operations comparisons were also negatively impacted by relative changes in foreign currency exchange rates, which decreased income from operations by $1.2 million for the quarter and $2.4 million for the year.

Kronos’ net sales of $310.4 million in the fourth quarter of 2007 were $12.0 million, or 4%, higher than in the fourth quarter of 2006.  Net sales of $1.3 billion for the full year 2007 were $30.9 million, or 2%, higher than the full year 2006.  Kronos’ net sales increased as the favorable effect of fluctuations in foreign currency exchange rates, which increased sales by approximately $21 million for the quarter and $65 million for the year, and higher TiO2 sales volumes more than offset the unfavorable effect of lower average TiO2 selling prices.  Kronos’ average TiO2 selling prices in the fourth quarter of 2007 were 5% lower than the fourth quarter of 2006, and average prices were 4% lower for the year.  Kronos' TiO2 sales volumes in the fourth quarter of 2007 increased 2% as compared to the fourth quarter of 2006, with higher volumes in United States and export markets during the quarter.  Sales volumes were 1% higher for the full year, as higher volumes in European and export markets were partially offset by lower volumes in North America.  Kronos’ TiO2 sales volumes in 2007 were a new record for Kronos.The table at the end of this release shows the impact of each of these items on Kronos’ sales.

Kronos’ income from operations for the fourth quarter of 2007 declined by 73% to $10.0 million compared to the same period in 2006 and declined by 41% to $84.9 million for the full year 2007 compared to 2006.   The decreases in Kronos’ income from operations were due primarily to lower average TiO2 selling prices, lower production volumes and higher manufacturing costs, partially offset by the favorable effect of higher TiO2 sales volumes.  Kronos’ TiO2 production volumes were 6% lower in the fourth quarter of 2007 as compared to the fourth quarter of 2006, and were 1% lower for the year.  Kronos’ income from operations comparisons were also impacted by fluctuations in foreign currency exchange rates, which decreased Kronos’ income from operations by approximately $7 million for the quarter and $4 million for the year.

Kronos’ provision for income taxes in 2007 includes (i) a non-cash charge of $90.8 million (NL’s equity interest was $21 million after tax or $.43 per diluted share) primarily related to the reduction in Kronos’ net deferred income tax asset in Germany resulting from the enactment of legislation reducing the income tax rates, (ii) a non-cash charge of $8.7 million (NL’s equity interest was $2 million, or $.04 per diluted share, net of tax benefit) related to the adjustment of certain tax attributes of its German subsidiary, and (iii) a non-cash income tax benefit of $2.0 million due to a net decrease in its reserve for uncertain tax positions.

In 2006, Kronos recognized an aggregate $34.9 million net income tax benefit (NL’s equity interest was $8.1 million after tax, or $.17 per diluted share) related to the net effects of the withdrawal of certain income tax assessments previously made by the Belgian and Norwegian tax authorities, the favorable resolution of certain income tax audit issues related to Kronos’ German and Belgian operations, the unfavorable resolution of certain other income tax issues related to the German operations, an increase in Kronos’ income tax contingency reserve principally related to ongoing income tax audits in Germany and the enactment of a reduction in the Canadian federal income tax rate.

Securities transactions gains in 2007 relate principally to a $22.7 million pre-tax gain ($14.7 million, or $.30 per diluted share, net of income taxes) recognized from the sale of 800,000 shares of TIMET common stock.  Insurance recoveries relate to amounts we received from certain of our insurance carriers in settlement of claims for certain environmental, indemnity and past litigation defense costs incurred by us.  These recoveries aggregated $5.6 million ($3.7 million, or $.08 per diluted share, net of income taxes) in 2007 and $7.7 million ($5.0 million, or $.10 per diluted share, net of income taxes) in 2006.  Corporate expenses were $4.7 million higher in the fourth quarter of 2007 compared to the same period in 2006 and were $7.1 million higher in 2007 compared to 2006 due mainly to higher litigation and related expenses.

Our income tax benefit in 2007 includes income of $1.3 million ($.03 per diluted share) due to a reduction in our reserve for uncertain tax positions.
