NL INDUSTRIES, INC. AND SUBSIDIARIES NOTES TO CONSOLIDATED FINANCIAL STATEMENTS Note 1 - Organization and basis of presentation: NL Industries, Inc. ("NL") conducts its titanium dioxide pigments ("TiO2") operations through its wholly owned subsidiary, Kronos, Inc. At March 31, 2003, Valhi, Inc., ("Valhi") and its subsidiaries held approximately 85% of NL's outstanding common stock, and Contran Corporation ("Contran") and its subsidiaries held approximately 90% of Valhi'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 each of Contran, Valhi and NL, may be deemed to control each of such companies. See Notes 6 and 7. The consolidated balance sheet of NL Industries, Inc. and Subsidiaries (collectively, the "Company") at December 31, 2002 has been condensed from the Company's audited consolidated financial statements at that date. The consolidated balance sheet at March 31, 2003 and the consolidated statements of income, comprehensive income, shareholders' equity and cash flows for the interim periods ended March 31, 2003 and 2002 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 in the U.S. ("GAAP") 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, 2002 (the "2002 Annual Report"). The Company has elected the disclosure alternative prescribed by Statement of Financial Accounting Standards ("SFAS") No. 123, "Accounting for Stock-Based Compensation," as amended by SFAS No. 148, "Accounting for Stock-Based Compensation - Transition and Disclosure," and to account for its stock-based employee compensation related to stock options in accordance with Accounting Principles Board Opinion ("APBO") No. 25, "Accounting for Stock Issued to Employees," and its various interpretations. Under APBO No. 25, no compensation cost is generally recognized for fixed stock options in which the exercise price is not less than the market price on the grant date. During the fourth quarter of 2002, following the cash settlement of certain stock options held by employees of the Company, the Company commenced accounting for its remaining stock options using the variable accounting method, which requires the intrinsic value of all unexercised stock options (including those with an exercise price at least equal to the market price on the date of grant) to be accrued as an expense, with subsequent increases (decreases) in the Company's market price resulting in additional compensation expense (income). Net compensation income recognized by the Company in accordance with APBO No. 25 in the first quarter of 2003 was $.5 million and net compensation cost recognized by the Company in the first quarter of 2002 was nil. -10-

The following table illustrates the effect on net income and earnings per share if the Company had applied the fair value recognition provisions of SFAS No. 123 to stock-based employee compensation. Three months ended March 31, ---------------------------- 2003 2002 --------- --------- (In thousands, except per share amounts) Net income - as reported ........................... $ 9,430 $ 6,384 Deduct: Stock-based compensation income, net of tax, included in reported net income .............

(120) (271) --------- --------- Net income - pro forma ............................. $ 8,971 $ 6,113 ========= ========= Net income per basic common share: As reported .................................... $ .20 $ .13 Pro forma ...................................... $ .19 $ .13 Net income per diluted common share: As reported .................................... $ .20 $ .13 Pro forma ...................................... $ .19 $ .12 The Company adopted SFAS No. 143, "Accounting for Asset Retirement Obligations," effective January 1, 2003. Under SFAS No. 143, the fair value of a liability for an asset retirement obligation covered under the scope of SFAS No. 143 is recognized in the period in which the liability is incurred, with an offsetting increase in the carrying amount of the related long-lived asset. Over time, the liability is accreted to its future value, and the capitalized cost is depreciated over the useful life of the related asset. Upon settlement of the liability, an entity would either settle the obligation for its recorded amount or incur a gain or loss upon settlement. Under the transition provisions of SFAS No. 143, at the date of adoption on January 1, 2003 the Company recognized (i) an asset retirement cost capitalized as an increase to the carrying value of its property, plant and equipment, (ii) accumulated depreciation on such capitalized cost and (iii) a liability for the asset retirement obligation. Amounts resulting from the initial application of SFAS No. 143 were measured using information, assumptions and interest rates all as of January 1, 2003. The amount recognized as the asset retirement cost was measured as of the date the asset retirement obligation was incurred. Cumulative accretion on the asset retirement obligation, and accumulated depreciation on the asset retirement cost, were recognized for the time period from the date the asset retirement cost and liability would have been recognized had the provisions of SFAS No. 143 been in effect at the date the liability was incurred, through January 1, 2003. The difference between the amounts recognized as described above and the associated amounts recognized in the Company's balance sheet as of December 31, 2002 was recognized as a cumulative effect of change in accounting principle as of January 1, 2003. The effect of adopting SFAS No. 143 as of January 1, 2003, as summarized in the table below, did not have a material effect on the Company's consolidated financial position, results of operations or liquidity, and is not separately recognized in the accompanying statement of income. -11-

(.1) Decrease in liabilities previously accrued for closure and post closure activities ............................ .3 Asset retirement obligation recognized .................................. (.6) ---- Net impact ...................................................... $ -- ==== At March 31, 2003, the asset retirement obligation was approximately $.6 million and was included in other noncurrent liabilities. Accretion expense on the asset retirement obligation during the first quarter of 2003, included in cost of sales, was not material. If the Company had adopted SFAS No. 143 as of January 1, 2002, the asset retirement obligation would have been approximately $.5 million at each of January 1, 2002 and March 31, 2002, and the effect on the Company's reported net income for the three months ended March 31, 2002 would not have been material. 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. Note 3 - Business segment information: The Company's operations are conducted by Kronos in one operating business segment - the production and sale of TiO2.

("Tremont Group") and Tremont Corporation ("Tremont") both became wholly owned subsidiaries of Valhi. Under these merger transactions, (i) Valhi issued 3.5 million shares of its common stock to the Company in return for the Company's 20% ownership interest in Tremont Group and (ii) Valhi issued 3.4 shares of its common stock (plus cash in lieu of fractional shares) to all Tremont stockholders (other than Valhi and Tremont Group) in exchange for each share of Tremont common stock held by such stockholders. The Company received approximately 27,770 shares of Valhi common stock in the second transaction. The number of shares of Valhi common stock issued to the Company in exchange for the Company's 20% ownership interest in Tremont Group was equal to the Company's 20% pro-rata interest in the shares of Tremont common stock held by Tremont Group, adjusted for the same 3.4 exchange ratio. The Valhi common stock owned by the Company is restricted under SEC Rule 144. The Company reported a pre-tax securities transaction gain of approximately -13-

$2.3 million in the first quarter of 2003 which represented the difference between the market value of the shares of Valhi received and the cost basis of the Tremont Group and Tremont shares exchanged. Following these transactions, the Company owns approximately 4.7 million shares of Valhi's outstanding common stock (approximately 4% of Valhi's outstanding shares). The Company will continue to account for its shares of Valhi common stock as available-for-sale marketable equity securities carried at fair value (based on quoted market prices). The shares of Valhi common stock cannot be voted by the Company under Delaware Corporation Law, but the Company does receive dividends from Valhi on these shares, when declared. For financial reporting purposes, Valhi reports its proportional interest in these shares as treasury stock. Note 7 - Receivable from affiliates: In May 2001 a wholly owned subsidiary of the Company's majority-owned environmental management subsidiary, NL Environmental Management Services, Inc. ("EMS") loaned $20.0 million to the Harold C. Simmons Family Trust No. 2 (the "Family Trust"), one of the trusts described in Note 1, under a $25.0 million revolving credit agreement. The loan was approved by special committees of the Company's and EMS's Boards of Directors. The loan bears interest at prime (4.25% at March 31, 2003), is due on demand with 60 days notice and is collateralized by 13,749 shares, or approximately 35%, of Contran's outstanding Class A voting common stock and 5,000 shares, or 100%, of Contran's Series E Cumulative preferred stock, both of which are owned by the Family Trust. The value of the collateral is dependent, in part, on the value of the Company as Contran's interest in the Company, through its beneficial ownership of Valhi, is one of Contran's more substantial assets. At March 31, 2003, the outstanding loan balance was $18.0 million and $7.0 million was available for additional borrowing by the Family Trust.

In the first quarter of 2002, the Company recognized litigation settlement gains with former insurance carrier groups of $1.9 million to settle certain insurance coverage claims related to environmental remediation. No further material settlements relating to litigation concerning environmental remediation coverage are expected. -16-

Note 14 - Commitments and contingencies: For descriptions of certain legal proceedings, income tax and other commitments and contingencies related to the Company, reference is made to (i) Management's Discussion and Analysis of Financial Condition and Results of Operations, (ii) Part II, Item 1 - "Legal Proceedings," and (iii) the 2002 Annual Report. -17-

ITEM 2. MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS RESULTS OF OPERATIONS Three months ended % March 31, Change ------------------ ------ 2003 2002 ------ ------ (In millions, except percentages and metric tons) Net sales and operating income Net sales .................................... $253.0 $202.4 +25% Operating income ............................. $ 34.3 $ 22.2 +55% Operating income margin percentage ........... 14% 11% TiO2 operating statistics Percent change in average selling price (in billing currencies) ........................ +6% Sales volume (metric tons in thousands) ...... 118 112 +5% Production volume (metric tons in thousands) . 117 106 +11% Kronos' operating income in the first quarter of 2003 increased $12.1 million or 55% from the first quarter of 2002 primarily due to higher average selling prices and higher sales and production volumes, partially offset by higher operating costs, particularly energy costs. Compared with the fourth quarter of 2002, operating income in the first quarter of 2003 increased $14.2 million, or 71%, primarily due to higher sales and production volumes, higher average selling prices and lower operating costs. Kronos' average selling price in billing currencies (which excludes the effects of foreign currency translation) during the first quarter of 2003 was 6% higher than the first quarter of 2002 and was 1% higher than the fourth quarter of 2002. Compared with the fourth quarter of 2002, selling prices in billing currencies increased in all major markets. The average selling price in billing currencies in March 2003 was comparable to the average selling price for the first quarter of 2003. The Company expects higher average selling prices in billing currencies for full-year 2003 compared to full-year 2002. The Company discloses percentage changes in its average TiO2 selling prices in billing currencies (which excludes the effects of foreign currency translation), so that such changes can be analyzed without the impact of changes in foreign currency exchange rates, thereby facilitating period-to-period comparisons. 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. When translated from billing currencies to U.S. dollars using currency exchange rates prevailing during the respective periods, Kronos' first-quarter 2003 average selling price in U.S. dollars was 18% higher than in the first quarter of 2002 and 6% higher than the fourth quarter of 2002. First quarter 2003 sales volume of 118,000 metric tons was a record first quarter for Kronos and increased 5% from the first quarter of 2002 and increased 16% from the fourth quarter of 2002. Compared to the fourth quarter of 2002, sales volume increased in all major markets with each region up at least 10%. Kronos anticipates its sales volume for full year 2003 will be slightly higher than full year 2002. Finished goods inventory levels at the end of the first quarter decreased 2% from December 2002 levels and represented under two months of sales. First quarter 2003 production volume of 117,000 metric tons was an all-time quarterly record for Kronos and was 11% higher than the first quarter of 2002 and increased 9% from the fourth quarter of 2002 with operating rates near full capacity in the first quarter of 2003 compared with 96% of capacity in the first quarter of 2002. Increased production volume in the first quarter of -18-

2003 compared with fourth quarter 2002 was primarily due to maintenance stops in the fourth quarter. Kronos anticipates its production volume for full year 2003 will be higher than full year 2002. The Company currently expects TiO2 industry demand in 2003 to increase slightly over 2002 levels. Kronos' TiO2 production volume in 2003 is expected to approximate Kronos' 2003 TiO2 sales volume. In December 2002 and January 2003, Kronos announced additional price increases in Europe and North America which averaged approximately 8% in Europe and approximately 7% in North America. Kronos is hopeful that it will realize additional price increases during the remainder of 2003, but the extent to which Kronos can realize price increases will depend on market conditions and global economic recovery. Overall, the Company expects its TiO2 operating income in 2003 will be higher than 2002, primarily due to higher average TiO2 selling prices and higher sales and production volumes. The Company's expectations as to the future prospects of the Company and the TiO2 industry are based upon a number of factors beyond the Company's control, including worldwide growth of gross domestic product, competition in the marketplace, unexpected or earlier-than-expected capacity additions and technological advances. If actual developments differ from the Company's expectations, the Company's results of operations could be unfavorably affected. Compared to the year-earlier period, cost of sales as a percentage of net sales decreased in the first quarter of 2003 primarily due to higher average selling prices in billing currencies and higher production volume, partially offset by higher energy costs. Excluding the effects of foreign currency translation, which increased the Company's expenses in the first quarter of 2003 compared to year-earlier period, the Company's selling, general and administrative expenses, excluding corporate expenses, in the first quarter of 2003 were slightly higher than the first quarter of 2002. 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 weaker U.S. dollar compared to the euro in the first quarter of 2003 versus the year-earlier period, increased the dollar value of sales in the first quarter of 2003 by a net $26.6 million when compared to the year-earlier period. The effect of the weaker U.S. dollar on Kronos' operating costs that are not denominated in U.S. dollars increased operating costs in the first quarter of 2003 compared to the year-earlier period. In addition, sales to export markets are typically denominated in U.S. dollars and a weaker U.S. dollar decreases margins on these sales at the Company's non-U.S. subsidiaries. The unfavorable margin on export sales tends to offset the favorable effect of translating local currency profits to U.S. dollars when the dollar is weaker. As a result, the net impact of currency exchange rate fluctuations was not significant in the first quarter of 2003 when compared to the first quarter of 2002. -19-

General corporate The following table sets forth certain information regarding general corporate income (expense). Three months ended March 31, Difference ----------------------- ---------- 2003 2002 -------- -------- (In millions) Securities earnings ............ $ 3.1 $ 1.3 $ 1.8 Corporate income ............... .4 2.9 (2.5) Corporate expense .............. (15.3) (10.1) (5.2) Interest expense ............... (8.0) (6.5) (1.5) ------- ------- ------ $ (19.8) $ (12.4) $ (7.4) ======= ======= ====== Securities earnings for the first quarter of 2003 included a $2.3 million noncash securities transaction gain 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 Valhi completed in February 2003. See Note 6 to the Consolidated Financial Statements. In addition, interest income was lower in the first quarter of 2003 as compared with first quarter 2002 due to lower levels of available funds invested and lower average yields. The Company expects interest income to be lower for full-year 2003 than full-year 2002 due to lower average yields and lower average levels of funds available for investment. Corporate income for the first quarter of 2003 and 2002 included $.3 million and $1.0 million, respectively, of fee income related to a covenant not to compete agreement related to the sale of Rheox in 1998. The agreement became fully amortized in January 2003. See Note 13 to the Consolidated Financial Statements. Corporate income for the first quarter of 2002 also included a $1.9 million litigation settlement gain with former insurance carrier groups. Corporate expense for the first quarter of 2003 was $15.3 million, an increase of $5.2 million compared with the first quarter of 2002 primarily due to higher environmental expenses related to remediation of formerly owned business units. Compared to the fourth quarter of 2002, corporate expense in the first quarter of 2003 increased $5.6 million primarily due to higher environmental expenses partially offset by lower legal and stock option compensation expenses. Corporate expenses are expected to be higher for full-year 2003 as compared to full-year 2002 due to higher environmental expenses and higher legal expenses associated with the defense of lead pigment litigation, including two trials scheduled for 2003. Interest expense in the first quarter of 2003 was $8.0 million, an increase of $1.5 million from the first quarter of 2002 primarily due to higher levels of outstanding debt and associated currency effects, partially offset by lower interest rates. Assuming no significant change in interest rates, interest expense for full-year 2003 is expected to be higher than full-year 2002 due to higher levels of outstanding indebtedness, partially offset by lower average interest rates. -20-

Provision for income taxes The Company reduced its deferred income tax valuation allowance by $.7 million in the first quarter of 2003 and $.1 million in the first quarter of 2002 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 in the first quarter of 2002 primarily related to EMS. Recently adopted accounting principles As described in Note 1 in the Consolidated Financial Statements, the Company adopted Statement of Financial Accounting Standards No. 143, "Accounting for Asset Retirement Obligations," effective January 1, 2003. LIQUIDITY AND CAPITAL RESOURCES The Company's consolidated cash flows from operating, investing and financing activities for the three months ended March 31, 2003 and 2002 are presented below. Three months ended March 31, ------------------ 2003 2002 ------ ------ (In millions) Net cash provided (used) by: Operating activities: Before changes in assets and liabilities ......... $ 15.5 $ 15.2 Changes in assets and liabilities ................ (29.2) (2.4) ------ ------ (13.7) 12.8 Investing activities ................................. (4.4) (14.2) Financing activities ................................. 6.3 (38.2) ------ ------ Net cash used by operating, investing, and financing activities ......................... $(11.8) $(39.6) ====== ====== 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 flows from operations is the primary source of liquidity for the Company. Changes in TiO2 pricing, production volume and customer demand, among other things, could significantly affect the liquidity of the Company. Cash flow from operations, before changes in assets and liabilities, increased slightly in the first three months of 2003 from the comparable period in 2002 primarily due to $12.1 million of higher operating income partially offset by $5.2 million of higher corporate expenses, $2.5 million of lower corporate income and $2.2 million of lower net distributions from the Company's investment in its 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 three months of 2003 was significantly higher than the -21-

first three months of 2002 with higher inventory balances (net of raw material accruals), insurance proceeds collected in first quarter 2002 and decreases in accounts payable and accrued liabilities in the first three months of 2003. Inventories and accounts payable were affected by certain non-cash accruals for certain titanium ore contracts of $4.9 million and $31.6 million at December 31, 2002 and 2001, respectively. These non-cash accruals were reversed as raw materials were received under the contracts in the amounts of $4.9 million and $25.8 million in first quarters 2003 and 2002, respectively. Investing activities The Company's capital expenditures were $6.5 million and $5.5 million in the first three months of 2003 and 2002, respectively. Capital expenditures in first quarter 2002 included approximately $1.2 million related to reconstruction of the Company's Leverkusen, Germany sulfate plant damaged in the March 2001 fire. In January 2002, the Company acquired all of the stock and limited liability company units of EWI RE, Inc. and EWI RE, Ltd. (collectively "EWI"), respectively, for an aggregate of $9.2 million in cash, including capitalized acquisition costs of $.2 million. Financing activities In March 2003 the Company borrowed (euro)15.0 million ($16.1 million when borrowed) under the European Credit Facility. In April 2003 the Company repaid NOK 80 million (approximately $11 million when repaid) under the European Credit Facility. In the first quarter of 2003, the Company paid a regular quarterly dividend to shareholders of $.20 per share, aggregating $9.5 million. In the first quarters of 2003 and 2002, the Company repurchased nil and $3.3 million of treasury stock pursuant to its share repurchase program. The Company is authorized to repurchase approximately 1.3 million additional shares at May 9, 2003. The shares may be purchased over an unspecified period of time and, depending on market conditions, applicable legal requirements, available cash and other factors, the share repurchase program may be suspended at any time and could be terminated prior to completion. The repurchased shares are to be held as treasury shares available for general corporate purposes. Cash, cash equivalents, restricted cash and restricted marketable debt securities and borrowing availability At March 31, 2003, the Company had cash and cash equivalents aggregating $47 million ($22 million held by non-U.S. subsidiaries) and an additional $66 million of restricted cash equivalents and restricted marketable debt securities held by the Company, of which $10 million was classified as a noncurrent asset. At March 31, 2003, certain of the Company's subsidiaries had $83 million available for borrowing with approximately $43 million available under non-U.S. credit facilities (including $41 million under the European Credit Facility) and approximately $40 million under the U.S. Credit Facility. At March 31, 2003, the Company had complied with all financial covenants governing its debt agreements. -22-

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 penalties and interest. The Company's and EMS' 1998 U.S. federal income tax returns are being examined by the U.S. Internal Revenue Service ("IRS") and the Company and EMS have each granted extensions of the statute of limitations for assessment of tax with respect to their 1998 and 1999 income tax returns until September 30, 2004. Based upon the course of the examination, the Company anticipated that the IRS would propose a substantial tax deficiency, including penalties and interest, related to a restructuring transaction. In an effort to avoid protracted litigation and minimize the hazards of such litigation, the Company applied to take part in an IRS settlement initiative applicable to transactions similar to the restructuring transaction, and in April 2003 the Company received notification from the IRS that it had been accepted into the settlement initiative. Under the initiative, no penalties will be assessed and final settlement with the IRS is to be reached through negotiation and, if necessary, through a specified arbitration procedure. The Company anticipates that settlement of the matter will likely occur in 2004, resulting in payments of federal and state tax and interest ranging from $33 million to $45 million. Additional payments in later years may be required as part of the settlement. The Company has provided adequate accruals to cover the currently expected range of settlement outcomes. 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)10.4 million ($11.2 million at March 31, 2003). The Company has filed protests to the assessments for the years 1991 to 1997. The Company is in discussions with the Belgian tax authorities and believes that a significant portion of the assessments is without merit. In April 2003 the Company received a notification from the Belgian tax authorities of their intent to assess a tax deficiency related to 1999. The anticipated assessment, including interest, is expected to approximate (euro)12 million ($12.9 million at March 31, 2003). The Company believes the proposed assessment related to 1999 is without merit and in April 2003 filed a written response in opposition to the notification of intent to assess. In 2002, the Company received a notification from the Norwegian tax authorities of their intent to assess tax deficiencies of approximately NOK 12.2 million ($1.7 million at March 31, 2003) relating to 1998 through 2000. The Company has objected to this proposed assessment in a written response to the Norwegian tax authorities. In the first quarter of 2003, the Company was notified by the German Federal Fiscal Court (the "Court") that the Court had ruled in the Company's favor concerning a claim for refund suit in which the Company sought refunds of prior taxes paid during the periods 1990 through 1997. The Company expects to file amended German tax returns claiming such tax refunds for all years affected by the Court's decision, which is expected to result in a net refund of taxes and interest of approximately $30 million. As of March 31, 2003, the Company has not reflected this tax refund in its consolidated financial statements and expects to reflect the refund in its consolidated financial statements once certain procedural requirements are satisfied, including a review of the amended German tax returns by the German tax authorities. 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 -23-

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. At March 31, 2003 the Company had the equivalent of approximately $451 million of income tax loss carryforwards in Germany with no expiration date. However, the Company has provided a deferred tax valuation allowance against substantially all of these income tax loss carryforwards because the Company currently believes they do not meet the "more-likely-than-not" recognition criteria. In 2002, the German federal government proposed certain changes to its income tax law, including certain changes that would have imposed limitations on the annual utilization of income tax loss carryforwards. Such proposal, if enacted, would have significantly affected the Company's 2003 and future income tax expense and cash tax payments. In April 2003 the German federal government passed a new tax law which does not contain the provision that would have restricted the utilization of tax loss carryforwards. Furthermore, the provisions contained in the new law are not expected to materially impact the Company's income tax expense or cash tax payments. At March 31, 2003, the Company had net deferred tax liabilities of $141 million. The Company operates in numerous tax jurisdictions, in certain of which it has temporary differences that net to deferred tax assets (before valuation allowance). The Company has provided a deferred tax valuation allowance of $188 million at March 31, 2003, principally related to Germany, partially offsetting deferred tax assets which the Company believes do not currently meet the "more-likely-than-not" recognition criteria. 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 ($104 million at March 31, 2003) 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, the allocations of such costs among PRPs, and the financial viability of other 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 $145 million. The Company's estimates of such liabilities have not been discounted to present value. 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 the 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. At March 31, 2003, the Company had approximately $57 million in cash, cash equivalents and restricted marketable debt securities held by certain special purpose trusts, the assets of which can only be used to pay for certain -24-

of the Company's future environmental remediation and other environmental expenditures. 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 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 the precedent set by 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. The Company expects that additional lead pigment and lead-based litigation may be filed against the Company in the future asserting similar or different legal theories and seeking similar or different types of damages and relief. 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 dividend policy, 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; 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. -25-

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. 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, transportation interruptions, war and terrorist activities), 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 tax controversies, and other risks and uncertainties included in this Quarterly Report and in the 2002 Annual Report, and the uncertainties set forth from time to time in the Company's filings with the Securities and Exchange Commission. 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 publicly or revise such statements whether as a result of new information, future events or otherwise. ITEM 3. QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK For a discussion of the Company's market risks, refer to the caption "Quantitative and Qualitative Disclosures About Market Risk" in the 2002 Annual Report. There have been no material changes to the information provided that would require additional information with respect to the quarter ended March 31, 2003. ITEM 4. CONTROLS AND PROCEDURES The Company maintains a system of disclosure controls and procedures. The term "disclosure controls and procedures," as defined by regulations of the Securities and Exchange Commission ("SEC"), means controls and other procedures that are designed to ensure that information required to be disclosed in the reports that the Company files or submits to the SEC under the Securities Exchange Act of 1934, as amended (the "Act"), is recorded, processed, summarized and reported, within the time periods specified in the SEC's rules and forms. Disclosure controls and procedures include, without limitation, controls and procedures designed to ensure that information required to be disclosed by the Company in the reports that it files or submits to the SEC under the Act is accumulated and communicated to the Company's management, including its principal executive officer and its principal financial officer, as appropriate to allow timely decisions to be made regarding required disclosure. Each of J. Landis Martin, the Company's Chief Executive Officer, and Robert D. Hardy, the Company's Chief Financial Officer, have evaluated the Company's disclosure controls and procedures as of a date within 90 days of the filing date of this Form 10-Q. Based upon their evaluation, these executive officers have concluded that the Company's disclosure controls and procedures are effective as of the date of such evaluation. -26-

The Company also maintains a system of internal controls. The term "internal controls," as defined by the American Institute of Certified Public Accountants' Codification of Statement on Auditing Standards, AU Section 319, means controls and other procedures designed to provide reasonable assurance regarding the achievement of objectives in the reliability of the Company's financial reporting, the effectiveness and efficiency of the Company's operations and the Company's compliance with applicable laws and regulations. There have been no significant changes in the Company's internal controls or in other factors that could significantly affect such controls subsequent to the date of their last evaluation, including any corrective actions with regard to significant deficiencies and material weaknesses. -27-
