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. At March 31, 2001, Valhi, Inc. and Tremont Corporation, each affiliates of Contran Corporation, held approximately 60% and 20%, respectively, of NL's outstanding common stock. At March 31, 2001, Contran and its subsidiaries held approximately 93% of Valhi's outstanding common stock, and a subsidiary of Valhi and NL held approximately 80% of Tremont's outstanding common stock. Substantially all of Contran's outstanding voting stock is held by trusts established for the benefit of certain children and grandchildren of Harold C. Simmons, of which Mr. Simmons is sole trustee. Mr. Simmons, the Chairman of the Board of NL and the Chairman of the Board and Chief Executive Officer of Contran and Valhi and a director of Tremont, may be deemed to control each of such companies. See Notes 6 and 15. The consolidated balance sheet of NL Industries, Inc. and Subsidiaries (collectively, the "Company") at December 31, 2000 has been condensed from the Company's audited consolidated financial statements at that date. The consolidated balance sheet at March 31, 2001 and the consolidated statements of income, comprehensive income, shareholders' equity and cash flows for the interim periods ended March 31, 2001 and 2000 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. 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, 2000 (the "2000 Annual Report"). The Company adopted Statement of Financial Accounting Standards ("SFAS") No. 133, Accounting for Derivative Instruments and Hedging Activities, as amended, effective January 1, 2001. 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 are recognized as either assets or liabilities and measured at fair value. The accounting for changes in fair value of derivatives is dependent upon the intended use of the derivative. As permitted by the transition requirements of SFAS No. 133, as amended, the Company exempted from the scope of SFAS No. 133 all host contracts containing embedded derivatives which were issued or acquired prior to January 1, 1999. The Company is not a party to any significant derivative or hedging instrument covered by SFAS No. 133 at March 31, 2001, and there was no impact on the Company's financial statements from adopting SFAS No. 133. - 10 -

Note 2 - Earnings per share: Basic earnings per share is based on the weighted average number of common shares outstanding during each period. Diluted earnings per share is based on the weighted average number of common shares outstanding and the dilutive impact of outstanding stock options.

("EMS"), loaned $13.4 million to Tremont under a reducing revolving loan agreement in the first quarter of 2001. See Note 1. The loan was approved by special committees of the Company's and EMS's Board of Directors. The loan bears interest at prime plus 2% (10.5% at March 31, 2001), is due March 31, 2003 and is collateralized by 10.2 million shares of NL common stock owned by Tremont. The amount available for borrowing by Tremont is reduced by $250,000 per quarter, with the first reduction occurring on June 30, 2001. As a result, $1 million of the loan is classified as a current asset on March 31, 2001.

The Company recognized a $10.3 million net pretax gain in the first quarter of 2001. A majority of the proceeds from this settlement was transferred in April to a special-purpose trust established by the insurance carrier group to pay future remediation and other environmental expenditures of - 13 -

the Company. No further material settlements relating to litigation concerning environmental remediation coverage are expected. The Company also recognized a $.3 million pretax gain related to another litigation settlement in the first quarter of 2001.

The fire did not enter the Company's adjacent 125,000 metric ton chloride-process TiO2 plant ("Chloride Plant"), but did damage certain support equipment necessary to operate that plant. The damage to the support equipment resulted in a temporary shutdown of the Chloride Plant. On April 8, 2001, repairs to the damaged support equipment were substantially completed and full production resumed at the Chloride Plant. In April, the undamaged section of the Sulfate Plant resumed limited production (5% to 20% of capacity) of an intermediate form of TiO2 ("Hydrated TiO2"). The Hydrated TiO2 is being transported to the Company's Nordenham, Germany sulfate-process TiO2 plant to be further processed and finished into certain grades of TiO2. The Company's ability to produce the Hydrated TiO2 at the Sulfate Plant is limited by the available excess capacity at its Nordenham plant. The Company expects the Sulfate Plant to become 50% to 70% operational in August 2001 and fully operational in October 2001. The Company believes that the damage to property and the business interruption losses caused by the fire are covered by insurance, but the effect on the financial results of the Company on a quarter-to-quarter basis or a year-to-year basis will depend on the timing and amount of insurance recoveries. No insurance proceeds have been recognized during the first quarter of 2001 for the business interruption portion of the loss because the amount of such proceeds is presently not determinable. No provision for impairment of the damaged fixed assets has been recognized because the Company believes the insurance proceeds will exceed their carrying value. - 14 -

Note 13 - Condensed consolidating financial information: The Company's 11.75% Senior Secured Notes are collateralized by a series of intercompany notes to NL (the "Parent Issuer"). The Notes are also collateralized by a first priority lien on the stock of Kronos. A second priority lien on the stock of NL Capital Corporation ("NLCC") collateralized the notes until February 2000, at which time it was merged into KII and became included in the first priority lien on the stock of Kronos. In the event of foreclosure, the holders of the Notes would have access to the consolidated assets, earnings and equity of the Company. The Company believes the collateralization of the Notes, as described above, is the functional economic equivalent of a joint and several, full and unconditional guarantee of the Notes by Kronos and, prior to its merger into KII, NLCC. Management believes that separate financial statements would not provide additional material information that would be useful in assessing the financial position of Kronos and NLCC (the "Guarantor Subsidiaries"). In lieu of providing separate financial statements of the Guarantor Subsidiaries, the Company has included condensed consolidating financial information of the Parent Issuer, Guarantor Subsidiaries and non-guarantor subsidiaries in accordance with Rule 3-10 (e) of the SEC's Regulation S-X. The Guarantor Subsidiaries and the non-guarantor subsidiaries comprise all of the direct and indirect subsidiaries of the Parent Issuer. Investments in subsidiaries are accounted for by NL under the equity method, wherein the parent company's share of earnings is included in net income.

Note 15 - Subsequent event: In May 2001, a wholly owned subsidiary of EMS loaned $20 million to the Harold C. Simmons Family Trust #2 (the "Trust"), one of the trusts described in Note 1, under a new $25 million revolving credit agreement. The Trust owns 16,855 shares, or approximately 43%, of Contran's outstanding Class A voting common stock. The loan was approved by special committees of the Company's and EMS's Board of Directors. The loan bears interest at prime (7.5% at the time of the loan), is due on demand with 60 days notice and is collateralized by 15,768 shares of the Contran Class A common stock held by the Trust. -24-

MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS - -------------------------------------------------------------------------------- RESULTS OF OPERATIONS Three months ended % March 31, Change ------------------ ------ 2001 2000 ---- ---- (In millions, except percentages and metric tons) Net sales and operating income Net sales .......................................... $226.1 $231.0 -2% Operating income ................................... $ 51.9 $ 46.2 +12% Operating income margin percentage ................. 23% 20% TiO2 operating statistics Percent change in average selling prices (in billing currencies) ........................... +5% Sales volume (metric tons in thousands) ............ 103 111 -7% Production volume (metric tons in thousands) ....... 108 106 +2% Kronos' operating income in the first quarter of 2001 increased $5.7 million or 12% from the first quarter of 2000 due to higher average selling prices in billing currencies and higher production volume, partially offset by lower sales volume. Kronos' average selling price in billing currencies (which excludes the effects of foreign currency translation) during the first quarter of 2001 was 5% higher than the first quarter of 2000 and 1% lower than the fourth quarter of 2000. Compared to the fourth quarter of 2000, prices were lower in all major markets. The average selling price in billing currencies in March was 1% lower than the average selling price during the first quarter. Market conditions in the TiO2 industry have generally stalled the Company's efforts to increase prices. The Company believes worldwide economic conditions will determine whether any price increases will be realized during the remainder of the year. Kronos' first-quarter 2001 sales volume decreased 7% from the record first quarter of 2000 and increased 11% from the fourth quarter of 2000. Sales volume in the first quarter of 2001 was 7% and 11% lower in Europe and North America, respectively, compared to the first quarter of 2000 while export volume increased by 7%. Compared to the fourth quarter of 2000, sales volume increased by more than 10% in each of Kronos' major markets. Finished goods inventory levels at the end of March increased slightly from December 2000 levels and represent about two months of sales. First-quarter 2001 production volume was 2% higher than the comparable 2000 period with operating rates near full capacity in both periods. Production at the Company's Leverkusen facility was adversely affected late in the first quarter by a fire on March 20, 2001. See Note 12 to the Consolidated Financial Statements. Production rates at the Company's Leverkusen chloride-process plant returned to full capacity on April 8th, and the Company's Leverkusen sulfate-process plant is expected to be 50% to 70% operational in August 2001 and fully operational in October 2001. The Company believes that the damage to property and the business interruption losses caused by the fire are covered by insurance, but the effect on the financial results of the Company on a quarter-to-quarter basis or a year-to-year basis will depend on the timing and amount of insurance recoveries. No insurance -25-

proceeds have been recognized during the first quarter of 2001 for the business interruption portion of the loss because the amount of such proceeds is presently not determinable. No provision for impairment of the damaged fixed assets has been recognized because the Company believes the insurance proceeds will exceed their carrying value. Kronos anticipates its TiO2 sales and production volumes for full-year 2001 will be lower than that of 2000, in part due to the effect of the fire. Kronos expects its full-year 2001 operating income, excluding fire- related insurance recoveries, will be lower than 2000 primarily because of lower sales and production volumes and higher costs, particularly for energy. Although the Company believes its average selling price in billing currencies could continue a downward trend throughout the rest of 2001, it expects its average selling price for full-year 2001 to be only slightly below the full-year average price in 2000. Kronos' cost of sales as a percentage of net sales decreased in the first quarter of 2001 primarily due to higher average selling prices in billing currencies and higher production volume. Excluding the effects of foreign currency translation, which decreased the Company's expenses in the first quarter of 2001 compared to year-earlier period, the Company's selling, general and administrative expenses, excluding corporate expenses, in the first quarter of 2001 were comparable to the first quarter of 2000. A significant amount of Kronos' sales and operating costs are denominated in currencies other than the U.S. dollar. Fluctuations in the value of the U.S. dollar relative to other currencies, primarily a stronger U.S. dollar compared to the euro in the first quarter of 2001 versus the year-earlier period, decreased the dollar value of sales in the first quarter of 2001 by a net $11 million compared to the first quarter of 2000. When translated from billing currencies to U.S. dollars using currency exchange rates prevailing during the respective periods, Kronos' first-quarter 2001 average selling price in U.S. dollars was approximately 1% higher than in the first quarter of 2000 and 2% higher than the fourth quarter of 2000. The effect of the stronger U.S. dollar on Kronos' operating costs that are not denominated in U.S. dollars reduced operating costs in the 2001 period compared to the year-earlier period. In addition, sales to export markets are typically denominated in U.S. dollars and a stronger U.S. dollar improves margins on these sales at the Company's non-U.S. subsidiaries. The favorable margin on export sales tends to offset the unfavorable effect of translating local currency profits to U.S. dollars when the dollar is stronger. As a result, the net impact of currency exchange rate fluctuations on operating income in the first quarter of 2001 was not significant when compared to the first quarter of 2000. General corporate The following table sets forth certain information regarding general corporate income (expense). Three months ended March 31, Difference --------------------- ---------- 2001 2000 ---- ---- (In millions) Securities earnings ............... $ 2.6 $ 1.7 $ .9 Corporate income .................. 11.6 1.1 10.5 Corporate expense ................. (6.8) (6.1) (.7) Interest expense .................. (7.0) (7.9) .9 ------- ------- ------- $ .4 $ (11.2) $ 11.6 ======= ======= ======= -26-

Corporate income in the first quarter of 2001 includes $10.6 million of net insurance settlement gains, including a $10.3 million net gain from a settlement with the remaining members of the second of the Company's two principal former insurance carrier groups. See Note 11 to the Consolidated Financial Statements. No further material settlements relating to litigation concerning environmental remediation coverage are expected. Corporate expense was higher in the first quarter of 2001 primarily due to higher environmental remediation accruals and higher legal fees. Interest expense in the first quarter of 2001 decreased 11% from the comparable period in 2000 primarily due to lower average interest rates as a result of the December 2000 refinancing of $50 million of the Company's high fixed-rate public debt with lower variable-rate bank debt and lower levels of outstanding debt. The Company expects its full-year 2001 interest expense will be lower than 2000. Provision for income taxes The Company reduced its deferred income tax valuation allowance by $.7 million in the first quarter of 2001 and $1.3 million in the first quarter of 2000 primarily as a result of utilization of certain tax attributes for which the benefit had not been previously recognized under the "more-likely-than-not" recognition criteria. Other Minority interest primarily relates to the Company's majority-owned environmental management subsidiary, NL Environmental Management Services, Inc. ("EMS"). LIQUIDITY AND CAPITAL RESOURCES The Company's consolidated cash flows from operating, investing and financing activities for the three months ended March 31, 2001 and 2000 are presented below. Three months ended March 31, ------------------- 2001 2000 ------- ------- (In millions) Net cash provided (used) by: Operating activities: Before changes in assets and liabilities ....... $ 39.2 $ 37.0 Changes in assets and liabilities ..............

(9.6) (17.7) ------- ------- Net cash provided (used) by operating, investing, and financing activies .............. $ (18.7) $ .8 ======= ======= Operating activities The TiO2 industry is cyclical and changes in economic conditions within the industry significantly affect the earnings and operating cash flows of the Company. Cash flow from operations, before changes in assets -27-

and liabilities, in the 2001 period increased slightly from the comparable period in 2000 primarily due to higher operating income, partially offset by lower cash distributions from the Company's TiO2 manufacturing joint venture. The net cash used to fund changes in the Company's inventories, receivables and payables (excluding the effect of currency translation) in the first quarter of 2001 was significantly higher than the first quarter of 2000 due to higher accounts receivable balances and decreases in accounts payable and accrued liabilities in the first quarter of 2001. Investing activities In February 2001, EMS loaned $13.4 million to Tremont under a reducing revolving loan agreement. See Note 1 to the Consolidated Financial Statements. The loan was approved by special committees of the Company's and EMS's Board of Directors. The maximum amount available under the agreement is $13.4 million, which will decrease by $250,000 each quarter beginning June 30, 2001. The loan bears interest at prime plus 2% (10.5% at March 31, 2001), is due March 31, 2003 and is collateralized by 10.2 million shares of NL common stock owned by Tremont. In May 2001, a wholly owned subsidiary of EMS loaned $20 million to the Harold C. Simmons Family Trust #2 (the "Trust"), one of the trusts described in Note 1 to the Consolidated Financial Statements, under a new $25 million revolving credit agreement. The Trust owns 16,855 shares, or approximately 43%, of Contran's outstanding Class A voting common stock. The loan was approved by special committees of the Company's and EMS's Board of Directors. The loan bears interest at prime (7.5% at the time of the loan), is due on demand with 60 days notice and is collateralized by 15,768 shares of the Contran Class A common stock held by the Trust. Financing activities In the first quarter of 2001, the Company paid a regular quarterly dividend to shareholders of $.20 per share, aggregating $10 million. On May 9, 2001, the Company's Board of Directors declared a regular quarterly dividend of $.20 per share to shareholders of record as of June 13, 2001 to be paid on June 27, 2001. Cash, cash equivalents, restricted cash equivalents and borrowing availability At March 31, 2001, the Company had cash and cash equivalents aggregating $100 million ($39 million held by non-U.S. subsidiaries) and an additional $86 million of restricted cash equivalents held by U.S. subsidiaries, of which $11 million was classified as a noncurrent asset. The Company's subsidiaries had $15 million available for borrowing at March 31, 2001 under existing non-U.S. credit facilities. Income tax contingencies 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 interest. The Company has received tax assessments from the Norwegian tax authorities proposing tax deficiencies, including related interest, of approximately NOK 40 million ($4.3 million at March 31, 2001) pertaining to 1994 and 1996. The Company is currently litigating the primary issue related to the 1994 assessment, and in February 2001 the Norwegian Appeals Court ruled in favor of the Norwegian tax authorities. -28-

The Company has appealed the case to the Norwegian Supreme Court and believes that the outcome of the 1996 case is dependent on the eventual outcome of the 1994 case. The Company has granted a lien on its Fredrikstad, Norway TiO2 plant in favor of the Norwegian tax authorities. The Company has received preliminary tax assessments for the years 1991 to 1997 from the Belgian tax authorities proposing tax deficiencies, including related interest, of approximately euro 12.9 million ($11.4 million at March 31, 2001). The Company has filed protests to the assessments for the years 1991 to 1996 and expects to file a protest for 1997. The Company is in discussions with the Belgian tax authorities and believes that a significant portion of the assessments are without merit. No assurance can be given that the Company's tax matters will be favorably resolved due to the inherent uncertainties involved in court and tax 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. Environmental matters and litigation 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, including sites for which EMS has contractually assumed the Company's obligation. The Company believes it has adequate accruals ($111 million at March 31, 2001) 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 $170 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 either 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. The imposition of more stringent standards or requirements under environmental laws or regulations, new developments or changes with respect to site cleanup costs or allocation of such costs among PRPs, or a determination that the Company is potentially responsible for the release of hazardous substances at other sites, could result in expenditures in excess of amounts currently estimated by the Company to be required for such matters. Furthermore, there can be no assurance that additional environmental matters will not arise in the future. Lead pigment litigation The Company is also a defendant in a number of legal proceedings seeking damages for personal injury and property damage arising out of 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 -29-

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 reasonably be estimated. In addition, various legislation and administrative regulations have, from time to time, been enacted or proposed that seek to (a) 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 (b) 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, and bills which would revive actions barred by the statute of limitations. 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 position, results of operations or liquidity. There can be no assurance that additional matters of these types will not arise in the future. See Item 1 - "Legal Proceedings." Other 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; repurchase shares of its common stock; 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 or other industries, as well as the acquisition of interests in, and loans to, related companies. 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. Special note regarding forward-looking statements The statements contained in this Report on Form 10-Q ("Quarterly Report") which are not historical facts, including, but not limited to, statements found under the captions "Results of Operations" and "Liquidity and Capital Resources" above, 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," "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. Such statements by their nature involve risks and uncertainties, including, but not limited to, the cyclicality of the titanium dioxide industry, global economic and political conditions, global productive capacity, customer inventory levels, changes in product pricing, changes in product costing, changes in foreign currency exchange rates, competitive technology positions, operating interruptions (including, but not limited to, labor disputes, leaks, fires, explosions, unscheduled downtime and transportation interruptions), recoveries from insurance claims and the timing thereof, the ultimate resolution of pending or possible future lead pigment litigation and legislative developments related to the lead paint litigation, the outcome of other litigation, and other risks and uncertainties included in this Quarterly Report and in the 2000 Annual Report, and the uncertainties set forth from time to time in the Company's other public reports and filings. Should one or more of these risks materialize (or the consequences of such a development worsen), or should the underlying -30-

assumptions prove incorrect, actual results could differ materially from those forecasted or expected. The Company disclaims any intention or obligation to update publicly or revise such statements whether as a result of new information, future events or otherwise. PART II. OTHER INFORMATION ITEM 1. LEGAL PROCEEDINGS Reference is made to the 2000 Annual Report for descriptions of certain previously reported legal proceedings. Jackson, et al. v. The Glidden Co., et al. (No. 236835). In March 2001 the trial court denied plaintiffs' motion for class certification. State of Rhode Island v. Lead Industries Association, et al. (No. 99-5226). In April 2001 the trial court dismissed all claims for special education costs; granted defendants' motions to dismiss the equitable- relief-to-children claim, the Unfair Trade Practices Act claim except insofar as it seeks to recover damages for post-1970 conduct, and the strict liability, negligence and misrepresentation claims except insofar as they relate to state-owned buildings; and denied defendants' motions to dismiss the public nuisance, civil conspiracy, unjust enrichment, and indemnity claims. City of St. Louis v. Lead Industries Association, et al. (No. 002-245). In March 2001 the federal court remanded the case to state court. County of Santa Clara v. Atlantic Richfield Company, et al. (No. CV788657). In March 2001 defendants renewed their demurrers and motions to strike all claims. The court has not ruled. Lewis, et al. v. Lead Industries Association, et al. (No. CH09800). In March 2001 defendants moved to dismiss all claims. The court has not ruled. Borden, et al. v. The Sherwin Williams Company, et al. (No. 2000-587). In March 2001 defendants removed to Federal court and moved to dismiss the fraudulent concealment and misrepresentation and negligence claims. In April 2001 plaintiffs moved to remand to State court. In April 2001 a complaint was filed in City of Milwaukee v. NL Industries, Inc. and Mautz Paint (Circuit Court, Civil Division, Milwaukee County, Wisconsin, Case No. 01CV003066). Plaintiff seeks compensatory and equitable relief for lead hazards in Milwaukee homes, restitution for amounts it has spent to abate lead, and punitive damages. The complaint asserts public nuisance, restitution, and conspiracy claims against the Company. The Company has not been served. The Company intends to deny all allegations of wrongdoing and liability and to defend itself vigorously. In April 2001 a complaint was filed in Harris County, Texas v. Lead Industries Association, et al. (No. 2001-21413). The complaint seeks actual and punitive damages and asserts the Company, six other former manufacturers of lead pigment and a trade association are jointly and severally liable for past and future damages due to the presence of lead paint in County-owned buildings. The Complaint asserts claims for strict liability, negligence, fraudulent misrepresentation, negligent misrepresentation, concert of action, public -31-

nuisance, restitution, and conspiracy. The Company has not been served. The Company intends to deny all allegations of wrongdoing and liability and to defend itself vigorously. It is possible that other governmental entities or other plaintiffs may file claims related to lead pigment and paint similar to those described above and in the 2000 Annual Report. ITEM 4.

      WHEREAS,  Tremont  desires that NL provide certain tax services and use of
NL's corporate  aircraft to Tremont,  and NL is willing to provide such services
