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 September 30, 2001, Valhi, Inc. and Tremont Corporation, each affiliates of Contran Corporation, held approximately 61% and 21%, respectively, of NL's outstanding common stock. At September 30, 2001, Contran and its subsidiaries held approximately 94% of Valhi's outstanding common stock, and a company 80% owned by Valhi and 20% owned by 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 Note 6. 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 September 30, 2001 and the consolidated statements of income, comprehensive income, shareholders' equity and cash flows for the interim periods ended September 30, 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 September 30, 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. Note 3 - Business segment information: The Company's operations are conducted by Kronos in one operating business segment - the production and sale of TiO2.

In the second quarter of 2000, the Company recognized a $5.6 million securities gain related to common stock received from the demutualization of an insurance company from which the Company had purchased certain insurance policies. Note 12 - Leverkusen fire and insurance claim: A fire on March 20, 2001 damaged a section of the Company's Leverkusen, Germany 35,000 metric ton sulfate-process TiO2 plant ("Sulfate Plant") and, as a result, production of TiO2 at the Leverkusen facility was halted. 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. The Sulfate Plant became approximately 50% operational in September 2001 and became fully operational in late October 2001. During the third quarter of 2001, the Company's insurance carriers approved payment of $8 million ($6.8 million received as of September 30, 2001) as a partial payment for property damage costs and business interruption losses caused by the Leverkusen fire. Three million dollars of this payment represented partial compensation for business interruption losses which was recorded as a reduction of cost of sales to offset unallocated period costs that resulted from lost production. The remaining $5 million represented property damage recoveries against which the Company recorded $1.1 million of expenses related to clean-up costs, resulting in a net gain of $3.9 million. In the first nine months of 2001, the Company's insurance carriers approved payment of $18.5 million ($17.3 million received as of September 30, 2001) for losses caused by the Leverkusen fire, including the $8 million discussed above. Eight million dollars of this payment was for business interruption losses and the remaining $10.5 million was for property damage losses against which the Company recorded $4.7 million of expenses resulting in a net gain of $5.8 million. In October 2001, the Company reached an agreement in principle with its insurance carriers to settle the coverage claim involving the Leverkusen fire. The Company expects to receive an additional $38 million in insurance recoveries, of which approximately $13 million relates to property damage costs, and approximately $25 million relates to business interruption losses and extra expenses resulting from the fire. The Company expects to report a gain, net of certain expenses, related to this insurance settlement in the fourth quarter of 2001. Note 13 - Condensed consolidating financial information: The Company's 11.75% Senior Secured Notes (the "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. - 15 -

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. Elimination entries eliminate (i) the parent's investments in subsidiaries and the equity in earnings of subsidiaries, (ii) intercompany payables and receivables and (iii) other transactions between subsidiaries. - 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," (iii) the Company's Quarterly Report on Form 10-Q for the quarters ended March 31, 2001 and June 30, 2001, and (iv) the 2000 Annual Report. Note 15 - Accounting principles not yet adopted: The Company will adopt SFAS No. 143, Accounting for Asset Retirement Obligations, no later than 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 would be 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 would be accreted to its present value, and the capitalized cost would be 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. The Company is still studying this newly-issued standard to determine, among other things, whether it has any asset retirement obligations which are covered under the scope of SFAS No. 143, and the effect, if any, to the Company of adopting this standard has not yet been determined. The Company will adopt SFAS No. 144, Accounting for the Impairment or Disposal of Long-Lived Assets, no later than January 1, 2002. SFAS No. 144 retains the fundamental provisions of existing generally accepted accounting principles with respect to the recognition and measurement of long-lived asset impairment contained in SFAS No. 121, Accounting for the Impairment of Long-Lived Assets and for Long-Lived Assets to be Disposed of. However, SFAS No. 144 provides new guidance intended to address certain significant implementation issues associated with SFAS No. 121, including expanded guidance with respect to appropriate cash flows to be used to determine whether recognition of any long-lived asset impairment is required, and if required how to measure the amount of the impairment. SFAS No. 144 also requires that any net assets to be disposed of by sale be reported at the lower of carrying value or fair value less cost to sell, and expands the reporting of discontinued operations to include any component of an entity with operations and cash flows that can be clearly distinguished from the rest of the entity. The Company is still studying this newly-issued standard, and the effect, if any, to the Company of adopting SFAS No. 144 has not yet been determined. - 27 -

MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS - -------------------------------------------------------------------------------- RESULTS OF OPERATIONS Three months ended % Nine months ended % September 30, Change September 30, Change ------------------ ------ ------------------ ------ 2001 2000 2001 2000 -------- -------- ------ ------ (In millions, except percentages and metric tons) Net sales and operating income Net sales .................... $207.0 $242.3 -15% $653.1 $724.4 -10% Operating income ............. $ 36.2 $ 57.5 -37% $133.3 $166.5 -20% Operating income margin percentage ................. 18% 24% 20% 23% TiO2 operating statistics Percent change in average selling price (in billing currencies) ................ -6% n/c Sales volume (metric tons in thousands) ................. 103 113 -9% 311 343 -10% Production volume (metric tons in thousands) .............. 109 113 -4% 315 329 -4% Kronos' operating income in the third quarter of 2001 decreased $21.3 million or 37% from the third quarter of 2000 due to lower average selling prices in billing currencies and lower sales and production volumes. Kronos' operating income in the first nine months of 2001 decreased $33.2 million or 20% from the first nine months of 2000 due to lower sales and production volumes. Kronos' average selling price in billing currencies (which excludes the effects of foreign currency translation) during the third quarter of 2001 was 6% lower than the third quarter of 2000 and 4% lower than the second quarter of 2001. Compared to the second quarter of 2001, prices in billing currencies were lower in all major markets. The average selling price in billing currencies in September was 1% lower than the average selling price during the third quarter as prices continued to trend downward. Kronos' average selling price in billing currencies for the first nine months of 2001 was comparable to the first nine months of 2000. Due to the global economic slowdown, the Company expects its average selling price in billing currencies will continue to trend downward through the end of the year and perhaps into the first quarter of 2002. The Company expects a lower average selling price for full-year 2001 compared to the full-year average selling price in 2000. Kronos' third-quarter 2001 sales volume decreased 9% from the near record third quarter of 2000 and decreased 2% from the second quarter of 2001. Sales volume in the third quarter of 2001 was 17% and 4% lower in Europe and North America, respectively, compared to the third quarter of 2000, while export volume increased moderately. Compared to the second quarter of 2001, sales volume decreased in Europe and North America while sales volume increased moderately in the export markets. Sales volume in the first nine months of 2001 was 10% lower than in the first nine months of 2000. Kronos anticipates its sales volume for full-year 2001 will be lower than that of 2000. Finished goods inventory levels at the end of September represented about two months of sales. Third-quarter 2001 production volume was 4% lower than the comparable 2000 period with operating rates at 95% in the third quarter of 2001 compared to near full capacity in the third quarter of 2000. Kronos' - 28 -

production volume in the first nine months of 2001 was 4% lower than the first nine months of 2000 with operating rates at 94% in the first nine months of 2001 compared to near full capacity in the first nine months of 2000. The lower production volume was primarily related to lost sulfate-process production at the Company's Leverkusen facility due to the previously reported fire in March 2001. See Note 12 to the Consolidated Financial Statements. The Leverkusen sulfate-process plant became approximately 50% operational in September 2001 and became fully operational in late October 2001. Kronos anticipates its production volume for full-year 2001 will be lower than that of 2000. During the third quarter of 2001, the Company's insurance carriers approved payment of $8 million ($6.8 million received as of September 30, 2001) as a partial payment for property damage costs and business interruption losses caused by the Leverkusen fire. Three million dollars of this payment represented partial compensation for business interruption losses which was recorded as a reduction of cost of sales to offset unallocated period costs that resulted from lost production. The remaining $5 million represented property damage recoveries against which the Company recorded $1.1 million of expenses related to clean-up costs, resulting in a net gain of $3.9 million. In the first nine months of 2001, the Company's insurance carriers approved payment of $18.5 million ($17.3 million received as of September 30, 2001) for losses caused by the Leverkusen fire, including the $8 million discussed above. Eight million dollars of this payment was for business interruption losses and the remaining $10.5 million was for property damage losses against which the Company recorded $4.7 million of expenses resulting in a net gain of $5.8 million. In October 2001, the Company reached an agreement in principle with its insurance carriers to settle the coverage claim involving the Leverkusen fire. The Company expects to receive an additional $38 million in insurance recoveries, of which approximately $13 million relates to property damage costs, and approximately $25 million relates to business interruption losses and extra expenses resulting from the fire. The Company expects to report a gain, net of certain expenses, related to this insurance settlement in the fourth quarter of 2001. Kronos expects its full-year 2001 operating income will be significantly lower than 2000 primarily because of lower average selling prices in billing currencies, lower sales and production volumes and higher energy costs. Compared to the year-earlier periods, cost of sales as a percentage of net sales increased in both the third quarter and first nine months of 2001 primarily due to lower production volume. Excluding the effects of foreign currency translation, which decreased the Company's expenses in the third quarter and first nine months of 2001 compared to year-earlier periods, the Company's selling, general and administrative expenses, excluding corporate expenses, in the third quarter and first nine months of 2001 were slightly lower compared to the year-earlier periods. 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 third quarter and first nine months of 2001 versus the year-earlier periods, decreased the dollar value of sales in the third quarter and first nine months of 2001 by a net $6 million and $24 million, respectively, when compared to the year-earlier periods. When translated from billing currencies to U.S. dollars using currency exchange rates prevailing during the respective periods, Kronos' third-quarter 2001 average selling price in U.S. dollars was 9% lower than in the third quarter of 2000 and 4% lower than the second quarter of 2001. Kronos' average selling price in U.S. dollars for the first nine months of 2001 decreased 4% from the first nine months of 2000. The effect of the stronger U.S. dollar on Kronos' operating - 29 -

costs that are not denominated in U.S. dollars reduced operating costs in the third quarter and first nine months of 2001 compared to the year-earlier periods. 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 third quarter and first nine months of 2001 was not significant when compared to the year-earlier periods. General corporate The following table sets forth certain information regarding general corporate income (expense). Three months ended Nine months ended September 30, Difference September 30, Difference ------------------- ---------- ------------------- ---------- 2001 2000 2001 2000 ------- ------- ------- ------- (In millions) Securities earnings ...... $ 2.1 $ 2.5 $ (.4) $ 6.0 $ 11.6 $ (5.6) Corporate income ......... 1.1 1.0 .1 14.1 46.2 (32.1) Corporate expense ........ (6.2) (6.8) .6 (18.0) (23.0) 5.0 Interest expense ......... (6.9) (7.7) .8 (20.8) (23.5) 2.7 ------- ------- ------- ------- ------- ------- $ (9.9) $ (11.0) $ 1.1 $ (18.7) $ 11.3 $ (30.0) ======= ======= ======= ======= ======= ======= Securities earnings in the first nine months of 2001 declined from the comparable period in 2000 primarily due to a $5.6 million second-quarter 2000 securities gain related to common stock received from the demutualization of an insurance company from which the Company had purchased certain insurance policies. Corporate income in the first quarter of 2001 and the second quarter of 2000 includes litigation settlement gains with former insurance carrier groups of $10.6 million and $43 million, respectively. See Note 11 to the Consolidated Financial Statements. No further material settlements relating to litigation concerning environmental remediation coverage are expected. Corporate expense in the first nine months of 2001 was lower than the year-earlier period, primarily due to lower environmental remediation accruals and lower legal fees. Interest expense in the third quarter and first nine months of 2001 decreased 10% and 11%, respectively, from the comparable periods in 2000 primarily due to lower average interest rates as a result of the December 2000 refinancing of $50 million of the Company's fixed-rate public debt with lower variable-rate bank debt, and lower levels of outstanding debt. In the second and third quarters of 2001, the Company repaid $6.5 million and $14.9 million, respectively, of its euro-denominated short-term debt with excess cash flow from operations. The Company expects its full-year 2001 interest expense will be lower than full-year 2000. - 30 -

Provision for income taxes The Company reduced its deferred income tax valuation allowance by $1.3 million in the first nine months of 2001 and $2.1 million in the first nine months 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. Accounting principles not yet adopted See Note 15 to the Consolidated Financial Statements. 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 nine months ended September 30, 2001 and 2000 are presented below. Nine months ended September 30, ------------------ 2001 2000 -------- -------- (In millions) Net cash provided (used) by: Operating activities: Before changes in assets and liabilities .................... $ 97.2 $ 123.2 Changes in assets and liabilities ........................... (4.8) (4.0) -------- -------- 92.4 119.2 Investing activities ............................................ (56.1) (45.6) Financing activities ............................................ (59.8) (79.4) -------- -------- Net cash used by operating, investing, and financing activities $ (23.5) $ (5.8) ======== ======== 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 and liabilities, in the first nine months of 2001 decreased from the comparable period in 2000 primarily due to lower operating income. The net cash used to fund changes in the Company's inventories, receivables and payables (excluding the effect of currency translation) in the first nine months of 2001 was comparable to the first nine months of 2000 with higher inventory balances and decreases in accounts payable and accrued liabilities offset by decreases in accounts and notes receivable balances in the first nine months of 2001. - 31 -

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 Boards of Directors. The loan bears interest at prime plus 2% (8.75% at September 30, 2001), is due March 31, 2003 and is collateralized by 10.2 million shares of NL common stock owned by Tremont. The maximum amount available for borrowing by Tremont reduces by $250,000 per quarter. In each of the second and third quarters of 2001, Tremont repaid $250,000 of the loan. At September 30, 2001, the outstanding loan balance was $12.9 million and no amounts were available for additional borrowings 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 $25 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 (6.75% at September 30, 2001), 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 Trust. At September 30, 2001, $5 million was available for additional borrowing by the Trust. In the second and third quarters of 2001, the Company's capital expenditures include an aggregate of $11.7 million for the rebuilding of its Leverkusen sulfate plant. In the second and third quarters of 2001, the Company received $5.5 million and $5 million, respectively, of insurance proceeds for property damage resulting from the Leverkusen fire and paid $1 million and $1.1 million, respectively, of expenses related to repairs and clean-up costs. Financing activities In the second and third quarters of 2001, the Company repaid euro 7.6 million ($6.5 million when paid) and euro 16.4 million ($14.9 million when paid), respectively, of its euro-denominated short-term debt with excess cash flow from operations. In the third quarter of 2001, the Company paid a regular quarterly dividend to shareholders of $.20 per share, aggregating $9.9 million. Dividends paid during the first nine months of 2001 totaled $.60 per share or $29.9 million. On October 24, 2001, the Company's Board of Directors declared a regular quarterly dividend of $.20 per share to shareholders of record as of December 10, 2001 to be paid on December 24, 2001. Pursuant to its share repurchase program, the Company purchased 465,000 shares of its common stock at an aggregate cost of $7.1 million in the third quarter of 2001 and 677,000 shares at an aggregate cost of $9.9 million in the first nine months of 2001. In October 2001, the Company's Board of Directors authorized the purchase of up to an additional 1.5 million shares. An additional 13,000 shares at an aggregate cost of $.2 million were purchased in October 2001, with 1,576,000 shares remaining for purchase under the repurchase program. - 32 -

Cash, cash equivalents, restricted cash equivalents and borrowing availability At September 30, 2001, the Company had cash and cash equivalents aggregating $97 million ($59 million held by non-U.S. subsidiaries) and an additional $93 million of restricted cash equivalents held by U.S. subsidiaries, of which $13 million was classified as a noncurrent asset. The Company's subsidiaries had $25 million available for borrowing at September 30, 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 received tax assessments from the Norwegian tax authorities proposing tax deficiencies, including related interest, of NOK 39.3 million pertaining to 1994 and 1996. The Company was unsuccessful in appealing the tax assessments and in June 2001 paid NOK 39.3 million ($4.3 million when paid) to the Norwegian tax authorities. The Company was adequately reserved for this contingency. The lien on the Company's Fredrikstad, Norway TiO2 plant in favor of the Norwegian tax authorities has been released. The Company has received preliminary tax assessments for the years 1991 to 1998 from the Belgian tax authorities proposing tax deficiencies, including related interest, of approximately euro 13.6 million ($12.5 million at September 30, 2001). The Company has filed protests to the assessments for the years 1991 to 1997 and expects to file a protest for 1998. The Company is in discussions with the Belgian tax authorities and believes that a significant portion of the assessments is 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 ($106 million at September 30, 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. 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 - 33 -

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 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 - 34 -

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, transportation interruptions, war and terrorist activities), 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 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 and the Company's Quarterly Report on Form 10-Q for the quarters ended March 31, 2001 and June 30, 2001 for descriptions of certain previously reported legal proceedings. Brenner, et al. v. American Cyanamid, et al. (No. 12596-93). In November 2001, the Fourth Department intermediate appellate court unanimously affirmed the dismissal of plaintiff's complaint by the trial court. County of Santa Clara v. Atlantic Richfield Company, et al. (No. CV788657). In September 2001, the trial judge dismissed without leave to amend plaintiffs' nuisance claim and their product liabilities claims for properties not owned by plaintiffs. Sabater, et al. v. Lead Industries Association, et al. (No. 25533/98). In September 2001, the Federal Court dismissed the Federal Home Loan Mortgage Corporation and remanded the case to state court. City of Milwaukee v. NL Industries, Inc. and Mautz Paint (No. 01CV003066). In October 2001, the trial court denied the Company's motion to dismiss plaintiff's conspiracy claim for lack of particularity. Jefferson County School District v. Lead Industries Association, et al. (No. 2001-69). In July 2001, plaintiff filed a motion to remand the case to state court. - 35 -

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. Since the filing of the 2000 Annual Report, the Company has been named as a defendant in asbestos cases in various jurisdictions on behalf of approximately 2,000 additional personal injury claimants.

hereof on the  unpaid  balance of this Note as it may exist from time to time at
the rate (herein called the "Applicable Rate") equal to prime, determined at the
beginning of each calendar  quarter,  and in no event shall the Applicable  Rate
exceed the maximum interest rate permitted to be charged from time to time under
applicable law (herein called the "Maximum Rate").  The Applicable Rate shall be
determined  based upon the published prime rate.  Accrued  interest on this Note
shall be computed  daily on the basis of a 365-day/366  day year, as applicable,
applied to the unpaid  principal  balance at the close of business  each day and
the  aggregate  of such  daily  amounts  of  accrued  interest  shall be payable
quarterly on the first business day following the end of each calendar  quarter.
Notwithstanding  the foregoing,  if at any time the Applicable  Rate exceeds the
Maximum Rate,  the rate of interest  payable under this Note shall be limited to
the Maximum Rate as provided above.

        Subject to the terms and conditions set forth in this Note,  Payee shall
make Revolving Loans to Maker at any time and from time to time from the date of
this Note until the  Maturity  Date,  in an  aggregate  principal  amount not to
exceed at any one time $25,000,000 (the "Maximum Revolving Loan Amount") at such
time.  Revolving Loans made under this Note shall be in an integral  multiple of
$200,000 and shall be wired by Payee to the account of Maker  requested by Maker
prior to 3:00 p.m.,  New York time,  on the  borrowing  date  proposed by Maker.
Maker shall give Payee  irrevocable  written  notice of all  proposed  Revolving
Loans not later than three  business  days prior to the  proposed  borrowing  (a
"Borrowing Notice"). Such Borrowing Notice shall specify the aggregate principal
amount of the  Revolving  Loan that  Maker is  requesting  Payee to make and the
requested  effective date of the proposed  Revolving  Loan.  Each Revolving Loan
shall bear interest on the outstanding  principal  balance thereof from the date
such Revolving Loan is made at the Applicable  Rate.  Proceeds of each Revolving
Loan shall be used for the general  purposes of the Maker including to refinance
existing obligations of the Maker.

        Payee  shall,  and is  hereby  authorized  by Maker to,  endorse  on the
schedule attached hereto an appropriate  notation evidencing the date and amount
of each  Revolving  Loan from Payee and the date and amount of each  payment and
prepayment with respect thereto;  provided that the failure of the Payee to make
such a notation on this Note or any error in such notation  shall not affect the
obligations of Maker under this Note.

                                  Page 1 of 7

Maker shall pay Payee on the last day of each quarter end, in immediately available funds, a revolving loan commitment fee (the "Fee") equal to 1/2 of 1% per annum on the average unused amount of the Maximum Revolving Loan Amount for each quarter. Such Fee shall be computed on the basis of the actual number of days elapsed during the calendar quarter on the basis of a 365 or 366 day year, as applicable. Such Fee shall commence on the date of this Note and cease to accrue on the earlier of the Maturity Date or any termination of Payee's commitment to make Revolving Loans. Maker shall have the right at any time, in its sole discretion and upon not less than 10 days written notice to Payee, to permanently reduce or terminate the Maximum Revolving Loan Amount, provided, however, that each partial reduction thereof shall be in an integral multiple of $200,000. Any reduction of the Maximum Revolving Loan Amount shall be accompanied by payment in full of any principal over the reduced Maximum Revolving Loan Amount plus accrued interest thereon and accrued Fee computed as provided in the previous paragraph. Payee shall have the right at any time, in its sole discretion and upon not less than 60 days written notice to Maker (unless there shall have occurred and be continuing an Event of Default), to permanently reduce or terminate the Maximum Revolving Loan Amount, provided, however, that each partial reduction thereof shall be in an integral multiple of $200,000. Any reduction of the Maximum Revolving Loan Amount shall require Maker to remit payment in full of any principal over the reduced Maximum Revolving Loan Amount plus accrued interest and accrued Fee computed as provided in the paragraph above upon the expiration of such 60 day notice period. The principal balance of this Note may be prepaid and discharged in whole or in part by Maker at any time and from time to time, without premium, penalty or fee. Any such prepayment may be subsequently reborrowed. The Maker, signers, sureties, guarantors and endorsers of this Note, jointly and severally, except as otherwise expressly set forth herein, waive demand, presentment, notice of nonpayment or dishonor, diligence in collecting, grace, notice of any protest, and consent to all extensions for any periods of time and partial payments, before or after maturity. If this Note is not paid at maturity, howsoever such maturity may be brought about, and the same is placed in the hands of an attorney for collection, or if this Note is collected by suit or through bankruptcy, probate or other legal proceedings, Maker agrees to pay holder's costs of collection, when incurred, including reasonable attorney's fees. No delay in the payments to holder or in the exercise of any power or right under this Note, or under any instrument securing payment hereof or executed in connection herewith, shall operate as a waiver thereof, nor shall a single or partial exercise of any power or right preclude other or further exercise thereof or exercise of any other power or right. Payment of the indebtedness evidenced by this Note is secured by the security interests established by the following documents (the "Security Documents"), to wit: Page 2 of 7

A Security Agreement dated as of May 4, 2001 executed by the Maker and Payee covering certain securities owned by Maker. The term default shall include any or all of the following: (a) The assignment or voluntary or involuntary conveyance by Maker of legal or beneficial interest, or Maker's mortgage, pledge or grant of a security interest in any of the Collateral (as defined in the Security Agreement); or (b) The filing or issuance of a notice of any lien, warrant for distraint or notice of levy for taxes or assessment against the Collateral (except for those liens not securing indebtedness for borrowed money which are being contested in good faith and for which adequate reserves have been created); or (c) Maker's nonpayment of any installment of principal, interest or the Fee under this Note; or (d) The adjudication of Maker as bankrupt, or the taking of any voluntary action by Maker or any involuntary action against Maker seeking an adjudication of Maker as bankrupt, or seeking relief by or against Maker under any provision of the United States Bankruptcy Code; (e) The failure by Maker to comply with any other covenant in this Note or in the Security Documents; (f) Maker's default in any payment (regardless of amount) of principal or interest on any other indebtedness for borrowed money; or (g) Maker's default in the observance or performance of any other agreement or condition relating to any such other indebtedness for borrowed money or contained in any instrument evidencing, securing or relating thereto, or any other event shall occur or condition exist, the effect of which default or other event or condition is to cause, or to permit the holder of the indebtedness to cause, such other indebtedness for borrowed money to become due prior to its stated maturity. An "Event of Default" shall be deemed to have occurred immediately upon any default described in clause (d) or (g) above, if any default described in clauses (c) or (f) above is not cured within 5 days, and if any default described in clauses (a), (b), or (e) is not cured within 30 days after written notice from Payee to Maker. If an Event of Default relating to a default described in clause (d) above shall occur, the entire principal balance and accrued interest owing thereon shall automatically become due and payable, without presentment, demand, protest or notice of any kind, all of which are expressly waived by Maker, and the commitment to make Revolving Loans shall automatically be terminated. If any other Event of Default has occurred and is continuing, the entire principal Page 3 of 7

balance and accrued interest owing hereof shall at once become due and payable and the commitment to make Revolving Loans shall be terminated without notice, at the option of the Payee, and the property covered by the Security Documents shall be subject to foreclosure under applicable law. Failure to exercise this option shall not constitute a waiver of the right to exercise the same in the event of any subsequent default. In the event any payment, including interest or principal, required to be made under this Note is not made when due, interest on the overdue sum shall accrue at the Applicable Rate plus four percent. So long as the Note shall remain unpaid, the Maker shall furnish to the Payee: (a) as soon as available and in any event not later than 75 days after the end of each of the first three quarters of each fiscal year of the Maker, the unaudited balance sheet of the Maker as of the end of such quarter and the unaudited statements of income and cash flows of the Maker for the period commencing at the end of the previous year and ending with the end of such quarter, all in reasonable detail and duly certified with respect to such statements (subject to year-end adjustments) by the Trustee of the Maker as being complete and accurate in all material respects; (b) as soon as available and in any event not later than 75 days after the end of each of the first three quarters of each fiscal year of Contran Corporation, the unaudited consolidated balance sheet of Contran Corporation as of the end of such quarter and the unaudited consolidated statements of income and cash flows of Contran Corporation for the period commencing at the end of the previous year and ending with the end of such quarter, all in reasonable detail and duly certified with respect to such unaudited consolidated statements (subject to year-end adjustments) by an officer of Contran Corporation as being complete and accurate in all material respects; (c) as soon as available and in any event not later than 120 days after the end of each fiscal year of the Maker, a copy of the unaudited balance sheet of the Maker as of the end of such fiscal year and unaudited statement of income and of cash flows of the Maker for such fiscal year, all in reasonable detail and duly certified with respect to such statements by the Trustee of Maker as being complete and accurate in all material respects; (d) as soon as available and in any event not later than 120 days after the end of each fiscal year of Contran Corporation, a copy of the annual audit report for such year, including therein consolidated balance sheets of Contran Corporation as of the end of such fiscal year and consolidated statements of income and retained earnings and of cash flows of the Contran Corporation for such fiscal year, in each case with unqualified certification by PricewaterhouseCoopers LLP or other independent certified public accountants of national recognized standing reasonably acceptable to Payee.

                               SECURITY AGREEMENT

        THIS SECURITY  AGREEMENT (the  "Agreement"),  dated this 4th day of May,
2001,  by and  between The Harold C.  Simmons  Family  Trust No. 2  (hereinafter
called  "Pledgor"),  whose principal office is at 5430 LBJ Freeway,  Suite 1700,
Dallas TX 75240 and EMS Financial,  Inc. a New Jersey  corporation (the "Secured
Party"), in its capacity as the holder of the Note (as defined below).

        Section 1. Security Interest. For value received,  Pledgor hereby grants
to Secured Party, upon the terms and conditions of this Agreement, to secure the
"Obligation", as described in Section 2 below, a security interest in and to any
and all  present  or future  rights of  Pledgor  in and to all of the  following
rights,  interests  and property (all of the  following  being herein  sometimes
called the "Pledged Shares"):

               15,768  shares  of  Pledgor's  Class A Common  Stock  of  Contran
        Corporation, par value of $.01 per share.

As used in this  Agreement,  the  "Collateral"  shall include the Pledged Shares
together  with  any  and  all  products  and  proceeds  of the  Pledged  Shares,
including, without limitation, all dividends, cash, instruments,  subscriptions,
warrants and any other rights and options and other  property  from time to time
received,  receivable or otherwise  distributed in respect of or in exchange for
any or all of the Pledged Shares.

        Section  2.  Loan  Agreement.  This  Agreement  is  being  executed  and
delivered  pursuant to the terms,  conditions and  requirements  of that certain
Revolving Loan Note,  dated as of May 4, 2001  ("Revolving  Note"),  pursuant to
which  Secured  Party has loaned monies to, and may in the future loan monies to
Pledgor.  The security  interests herein granted  ("Security  Interests")  shall
secure full payment and performance of: (a) that certain  Revolving Loan Note of
even date herewith in the principal  amount of $25,000,000,  made by Pledgor and
payable  to the  order  of  Secured  Party  (such  note and any  notes  given in
modification,  renewal, extension or substitution thereof being herein sometimes
collectively referred to as the "Notes" and individually as the "Note"); and (b)
the due and punctual  observance and  performance  of each and every  agreement,
covenant and condition on Pledgor's part to be observed or performed  under this
Agreement or the Note (all of which debts,  duties,  liabilities and obligations
hereinbefore   described  and  covered  by  this  Agreement  and  the  Note  are
hereinafter referred to as the "Obligation").

        Section 3. Priority.  Pledgor  represents and warrants that the Security
Interests  are  first  and  prior  security  interests  in  and  to  all  of the
Collateral, subject to no other liens thereon or security interests therein.

        Section 4. Title to  Collateral.  Pledgor  represents  and  warrants  to
Secured Party that: (a) Pledgor is the sole, direct,  legal and beneficial owner
of the Collateral; (b) no dispute, right of offset, counterclaim,  or defense to
the Security Interests exists with respect to all or any part of the Collateral;
and (c) Pledgor will defend the Collateral against the claims and demands of all
persons other than any subordinate claims or liens permitted by Secured Party in
its sole discretion.

Section 5. Pledgor's Obligations. So long as the Note is outstanding, Pledgor covenants and agrees with Secured Party: (a) not to permit any part of the Collateral to be levied upon under any legal process; (b) not to dispose of any of the Collateral without the prior written consent of Secured Party; (c) to comply with all applicable federal, state and local statutes, laws, rules and regulations, the noncompliance with which could have a material and adverse effect on the value of the Collateral; and (d) to pay all taxes accruing after the date hereof which constitute, or may constitute, a lien against the Collateral, prior to the date when penalties or interest would attach to such taxes; provided, that Pledgor may contest any such tax claim if done diligently and in good faith. Pledgor agrees to execute and deliver to Secured Party (i) stock powers appropriately endorsed in blank, with respect to the Collateral, and (ii) such other documents of transfer as Secured Party may from time to time request to enable Secured Party to transfer the Collateral into its name or the name of its nominee. Pledgor agrees (i) immediately to deliver to Secured Party or its nominee all certificates evidencing any of the Collateral which may at any time come into the possession of Pledgor, (ii) to execute and deliver to Secured Party such financing statements as Secured Party may request with respect to the Collateral, and (iii) to take such other steps as Secured Party may from time to time reasonably request to perfect Secured Party's security interest in the Collateral under applicable law. Pledgor agrees that this Agreement or a photocopy of this Agreement shall be sufficient as a financing statement. Section 6. Event of Default. As used herein, the term default shall include any or all of the following: (a) The assignment or voluntary or involuntary conveyance by Pledgor of legal or beneficial interest, or Pledgor's mortgage, pledge or grant of a security interest in any of the Collateral (as defined herein); or (b) The filing or issuance of a notice of any lien, warrant for distraint or notice of levy for taxes or assessment against the Collateral (except for those liens not securing indebtedness for borrowed money which are being contested in good faith and for which adequate reserves have been created); or (c) Pledgor's nonpayment of any installment of principal or interest or fees under the Note; or (d) The adjudication of Pledgor as bankrupt, or the taking of any voluntary action by Pledgor or any involuntary action against Pledgor seeking an adjudication of Pledgor as bankrupt, or seeking relief by or against Pledgor under any provision of the United States Bankruptcy Code; or (e) The failure by Pledgor to comply with any other covenant contained in the Note or this Agreement; or (f) Pledgor's default in any payment (regardless of amount) of principal of or interest on any other indebtedness for borrowed money; or -2-

(g) Pledgor's default in the observance or performance of any other agreement or condition relating to any such other indebtedness for borrowed money or contained in any instrument evidencing, securing or relating thereto, or any other event shall occur or condition exist, the effect of which default or other event or condition is to cause, or to permit the holder of the indebtedness to cause, such other indebtedness for borrowed money to become due prior to its stated maturity. An "Event of Default" shall be deemed to have occurred immediately upon any default described in clause (d) or (g) above; if any default described in clauses (c) or (f) above is not cured within 5 days; and if any default described in clauses (a), (b), or (e) is not cured within 30 days after written notice from Secured Party to Pledgor. Section 7. Remedies. Upon the occurrence and during the continuation of an Event of Default as defined herein, in addition to any and all other rights and remedies which Secured Party may then have hereunder or under the Note, under the Uniform Commercial Code of the State of New Jersey or of any other pertinent jurisdiction (the "Code"), or otherwise, Secured Party may, at its option: (a) reduce its claim to judgment or foreclosure or otherwise enforce the Security Interests, in whole or in part, by any available judicial procedure; (b) sell, or otherwise dispose of, at the office of Secured Party, or elsewhere, all or any part of the Collateral, and any such sale or other disposition may be as a unit or in parcels, by public or private proceedings, and by way of one or more contracts (it being agreed that the sale of any part of the Collateral shall not exhaust the Secured Party's power of sale, but sales may be made from time to time, and at any time, until all of the Collateral has been sold or until the Obligation has been paid and performed in full); (c) at its discretion, retain the Collateral in satisfaction of the Obligation whenever the circumstances are such that Secured Party is entitled to do so under the Code or otherwise; and (d) exercise any and all other rights, remedies and privileges he may have under the Note and the other documents defining the Obligation. Pledgor will pay to Secured Party all expenses (including, without limitation, court costs and attorneys' fees and expenses) of, or incident to, (i) the administration of this Agreement, (ii) the custody or preservation of, or the sale or collection of or other realization upon, any of the Collateral, (iii) the exercise or enforcement of any of the rights of Secured Party hereunder, or (iv) the failure by Pledgor to perform or observe any provision hereof. All such reimbursement obligations shall constitute a part of the Obligation. In view of the fact that federal and state securities laws may impose certain restrictions on the method by which a sale of the Collateral may be effected, Pledgor agrees that upon the occurrence and during the continuance of an Event of Default, Secured Party may, from time to time, attempt to sell all or any part of the Collateral by means of a private placement restricting the bidders and prospective purchasers to those who are qualified and will represent and agree that they are purchasing for investment only and not for distribution. In so doing, Secured Party may solicit offers to buy the Collateral, or any part of it, from a limited number of investors deemed by Secured Party, in its reasonable judgment, to be financially responsible parties who might be interested in purchasing the Collateral. If Secured Party solicits such offers, then the acceptance by Secured Party of the highest offer obtained therefrom shall be deemed to be a commercially reasonable method of disposing of such Collateral. -3-

Section 8. Application of Proceeds by Secured Party. Any and all proceeds ever received by Secured Party from any sale or other disposition of the Collateral, or any part thereof, or the exercise of any other remedy pursuant hereto shall be applied by Secured Party to the Obligation in such order and manner as Secured Party, in its sole discretion, may deem appropriate, notwithstanding any directions or instructions to the contrary by Pledgor; provided that the proceeds and/or accounts shall be applied toward satisfaction of the Obligation. Any proceeds received by Secured Party under this Agreement in excess of those necessary to fully and completely satisfy the Obligation shall be distributed to Pledgor. Section 9. Notice of Sale. Reasonable notification of the time and place of any public sale of the Collateral, or reasonable notification of the time after which any private sale or other intended disposition of the Collateral is to be made, shall be sent to Pledgor and to any other persons entitled under the Code to notice; provided, that if any of the Collateral threatens to decline speedily in value or is of a type customarily sold on a recognized market, Secured Party may sell, pledge, assign or otherwise dispose of the Collateral without notification, advertisement or other notice of any kind. It is agreed that notice sent or given not less than ten (10) calendar days prior to the taking of the action to which the notice relates is reasonable notification and notice for the purposes of this paragraph. Section 10. Right to Vote Collateral; Receipt of Dividends, Etc. (a) Unless an Event of Default shall have occurred and be continuing, the Pledgor shall have the right, from time to time, to vote and to give consents, ratifications and waivers with respect to the Collateral, and the Secured Party shall, upon receiving a written request from the Pledgor, which request shall be deemed to be a representation and warranty by the Pledgor that no Event of Default has occurred and is continuing, deliver to the Pledgor or, as specified in such request, such proxies, powers of attorney, consents, ratifications and waivers in respect of any Collateral which are registered in the name of the Secured Party or a nominee as shall be specified in such request and be in form and substance satisfactory to the Secured Party. (b) If an Event of Default shall have occurred and be continuing, all rights of the Pledgor to exercise the voting and other consensual rights which it would otherwise be entitled to exercise pursuant to Section 10 (a) above shall end upon five days' notice from the Secured Party to the Pledgor and thereafter the Secured Party shall have the right to the extent permitted by law, and the Pledgor shall take all such action as may be necessary or appropriate to give effect to such right, to vote and to give consents, ratifications and waivers, and take any other action with respect to all Collateral with the same force and effect as if the Secured Party were the absolute and sole owner thereof. (c) Unless an Event of Default shall have occurred and be continuing, the Pledgor shall be entitled to receive all regular cash dividends. Any other extraordinary dividends or distributions or proceeds therefrom on account of the Collateral shall, if received by the Pledgor, be received in trust for the benefit of the Secured Party, be segregated from the other property or funds of the Pledgor, and be forthwith delivered to the Secured Party as collateral in the same form as so received (with any necessary endorsement). -4-

Section 11. Delivery of Notices. Any notice or demand required to be given hereunder shall be in writing and shall be deemed to have been duly given and received, if given by hand, when a writing containing such notice is received by the person to whom addressed or, if given by mail, two (2) business days after a certified or registered letter containing such notice, with postage prepaid, is deposited in the United States mails, addressed to: If to Secured Party: EMS Financial, Inc. 16825 Northchase Drive Suite 1200 Houston TX 77060 Attn: Vice President and Secretary If to Pledgor: The Harold C. Simmons Family Trust No. 2 5430 LBJ Freeway Suite 1700 Dallas TX 75240 Attn: Trust Counsel Any such address may be changed from time to time by serving notice to the other party as above provided. A business day shall mean a day of the week which is not a Saturday or Sunday or a holiday recognized by national banking associations. Section 12. Binding Effect. This Agreement shall be binding upon Pledgor, its successors and assigns, and shall inure to the benefit of Secured Party, its heirs, successors, assigns, executors, administrators, and personal or legal representatives. Section 13. Governing Law. This Agreement shall be construed in accordance with and governed by the laws of the state of New Jersey. Section 14. Severability. In the event that any one or more of the provisions contained in this Agreement are held to be invalid, illegal or unenforceable in any respect, such invalidity, illegality or unenforceability shall not affect any other provision of this Agreement. Section 15. Lender Appointed Attorney-in-Fact. Upon the occurrence and during the continuance of an Event of Default, Pledgor hereby appoints Secured Party as Pledgor's attorney-in-fact, with full authority in the place and stead of Pledgor and in the name of Pledgor or otherwise, from time to time in its discretion to take any action and to execute any instrument which Secured Party may deem necessary or advisable to accomplish the purposes of this Agreement, including, without limitation, to receive, endorse and collect all instruments made payable to Pledgor representing any distribution, interest payment or other dividend or distribution in respect of the Collateral or any part thereof and to give full discharge for the same. This power of attorney created under this Section 15, being coupled with an interest, shall be irrevocable for the term of this Agreement and thereafter as long as any of the Obligation shall be -5-

outstanding, but shall not be deemed to authorize Secured Party to take an action which Pledgor could not be required to take hereunder. Section 16. Lender's Duty. Secured Party shall not be liable for any acts, omissions, errors of judgment or mistakes of fact or law including, without limitation, acts, omissions, errors or mistakes with respect to the Collateral, except with respect to Secured Party's custodial duties and for those arising out of or in connection with the Secured Party's gross negligence or willful misconduct. Without limiting the generality of the foregoing, Secured Party shall be under no obligation to take any steps necessary to preserve rights in the Collateral against any other parties but may do so at its option, and all expenses incurred in connection therewith shall be for the sole account of Pledgor, and shall be added to the Obligation secured hereby. -6-
