All other schedules are omitted because they are not applicable or not required. REPORT OF INDEPENDENT ACCOUNTANTS To the Pension and Employee Benefits Committee of NL Industries, Inc.: We have audited the accompanying statements of net assets available for plan benefits of the Savings Plan for Employees of NL Industries, Inc. as of December 31, 1992 and 1993, and the related statements of changes in net assets available for plan benefits for the years then ended. These financial statements are the responsibility of NL's Pension and Employee Benefits Committee. Our responsibility is to express an opinion on these financial statements based on our audits. We conducted our audits in accordance with generally accepted auditing standards. Those standards require that we plan and perform the audit to obtain reasonable assurance about whether the financial statements are free of material misstatement. An audit includes examining, on a test basis, evidence supporting the amounts and disclosures in the financial statements. An audit also includes assessing the accounting principles used and significant estimates made by NL's Pension and Employee Benefits Committee, as well as evaluating the overall financial statement presentation. We believe that our audits provide a reasonable basis for our opinion. In our opinion, the financial statements referred to above present fairly, in all material respects, the net assets available for plan benefits of the Savings Plan for Employees of NL Industries, Inc. as of December 31, 1992 and 1993, and the changes in net assets available for plan benefits for the years then ended in conformity with generally accepted accounting principles. Our audits were conducted for the purpose of forming an opinion on the basic financial statements taken as a whole. The supplemental schedules are presented for the purpose of additional analysis and are not a required part of the basic financial statements but are supplementary information required by the Department of Labor's Rules and Regulations for Reporting and Disclosure under the Employee Retirement Income Security Act of 1974. The supplemental schedules have been subjected to the auditing procedures applied in the audit of the basic financial statements and, in our opinion, are fairly stated, in all material respects, in relation to the basic financial statements taken as a whole.

SAVINGS PLAN FOR EMPLOYEES OF NL INDUSTRIES, INC. NOTES TO FINANCIAL STATEMENTS NOTE 1 - SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES: The financial statements of the Savings Plan for Employees of NL Industries, Inc. (the "Plan") have been prepared in accordance with generally accepted accounting principles. The following is a summary of the significant accounting policies followed by the Plan. Investments Investments are recorded at fair value based upon the quoted market price reported on the last trading day of the period for those securities listed on a national securities exchange; listed securities for which no sale was reported on that date are valued at the mean between the last reported bid and ask prices; and other investments not having an established market are valued at fair value as of that day determined in good faith by the outside advisor responsible for that investment. Short-term investments are stated at fair value. Purchases and sales of investments are reflected on a trade-date basis. Gains or losses on sales of securities are based on average cost. The Plan presents in the statements of changes in net assets available for plan benefits the net appreciation (depreciation) in the fair value of its investments which consists of the realized gains or losses and the unrealized appreciation (depreciation) on those investments. Contributions Contributions from employees are recorded in the period the employer makes payroll deductions from Plan participants. Employer contributions are accrued at the end of each year and are paid in the subsequent year. Investment income Income from investments is recorded as earned on an accrual basis. Dividend income is recorded at the ex-dividend date. Termination of plan Although it has not expressed any intent to do so, NL Industries, Inc. has the right under the Plan to discontinue contributions and to terminate the Plan at any time subject to penalties set forth in the Employee Retirement Income Security Act of 1974 ("ERISA"). In the event of such a discontinuance or termination of the Plan, the net assets of the Plan would be allocated to the Plan participants as prescribed by the Plan document, ERISA, and the Internal Revenue Code. NOTE 2 - PLAN DESCRIPTION: The Plan's principal objective is to provide eligible employees of NL Industries, Inc. and its Subsidiaries (the "Company") with a convenient way to save on a regular and long-term basis. The majority of the Company's U.S. employees are eligible to voluntarily participate in the Plan after six months of employment. At December 31, 1993 there were 279 active participants. Active participants may make basic contributions of between 1% and 8% of their eligible compensation. Basic contributions may consist of a combination of pre-tax and after-tax earnings. Generally, pre-tax contributions are excluded from the employee's taxable income until they are distributed. Eligible employees that have elected to make the maximum basic contribution of 8% may also make a supplemental pre-tax or after-tax contribution of between 1% and 4% of their eligible compensation. In accordance with the Tax Reform Act of 1986, participants are limited in the amount of salary reduction contributions which they may make to the Plan under Section 402(g) of the Internal Revenue Code ($8,994 annual maximum for 1993). Highly compensated participants may be required to adjust the amount of their contributions in order to permit the Plan to satisfy the nondiscrimination requirements of Sections 401(k) and 401(m) of the Internal Revenue Code. At December 31, 1993, the tests to determine compliance with such nondiscrimination requirements have not been performed. Contributions from highly compensated participants in excess of the amount that would allow the Plan to remain nondiscriminatory will be repaid to participants during 1994. At December 31, 1992, the payable to participants represents contributions received during 1992 from highly compensated participants in excess of the amount that would allow the Plan to remain nondiscriminatory. The Company contributes a discretionary amount of matching contributions, determined annually, wholly or partially contingent upon the attainment of certain profit objectives set by the Board of Directors of the Company. The employer match applies only to the employee's basic contributions. Employer contributions are fully vested upon death, retirement, or disability. A participant with less than three years of service is 0% vested in employer contributions, 50% vested following three years of service, 75% vested following four years of service and fully vested in all employer contributions following five years of service. Forfeitures of employer contributions may occur if a participant terminates employment prior to the full vesting period or if a participant or beneficiary, to whom a distribution is payable, cannot be located within five years of the date on which such distribution became payable. Amounts forfeited are used in the following order: (i) to restore the accounts of reemployed participants, (ii) to restore the accounts of participants or beneficiaries who apply for forfeited benefits and (iii) to reduce employer contributions. In October 1993, the Company consummated a manufacturing joint venture and transferred approximately 260 of its employees that were also plan participants to the newly-formed joint venture. At December 31, 1993, the Plan had not transferred the Plan assets of these participants to a plan sponsored by the joint venture (the "Joint Venture plan"); accordingly, the Plan has recorded a $2.4 million payable to the Joint Venture plan. Merrill Lynch Trust Company ("Merrill Lynch") serves as trustee for the Plan. Employees may elect to have their own contributions invested in one or more funds, whose investment objectives are as follows:
Number of participants at December 31, 1992 1993 MERRILL LYNCH RETIREMENT PRESERVATION TRUST - managed with the objective of 541 420 providing preservation of capital, liquidity and current income through investments primarily in Guaranteed Investment Contracts. MERRILL LYNCH BASIC VALUE FUND, INC. - CLASS A SHARES - managed with the 152 102 objective of seeking capital appreciation and, secondarily, income. MERRILL LYNCH FEDERAL SECURITIES TRUST - managed with the objective of 86 44 seeking a high current return through investments in U.S. government and government agency securities. MERRILL LYNCH CAPITAL FUND INC. - CLASS A SHARES - managed with the objective 291 186 of seeking the highest total investment return consistent with prudent risk, investing in equity, debt and convertible securities. MERRILL LYNCH GLOBAL HOLDINGS, INC. - CLASS A SHARES - managed with the 92 59 objective of seeking the highest total investment return consistent with prudent risk through world-wide investment in an internationally diversified portfolio of securities. NL STOCK FUND - invested primarily in NL common stock. 731 582
In addition to the six funds above, the Baroid Stock Fund holds investments in Baroid and Tremont common stock. Contributions or transfers into the Baroid Stock Fund are no longer allowed. Prior to the investment in securities of a type consistent with the objectives of any fund, cash may be temporarily invested in securities with maturities of less than one year issued or guaranteed by the U.S. government or any agency or instrumentality thereof or deposited in a bank savings account. Inter-fund transfers may be made daily, except that only one transfer per quarter may affect amounts in the NL Stock Fund. Only one transfer is permitted out of the Baroid Stock Fund which must be a transfer of the total value of the participant's account in that fund. Distributions to employees may occur during active service or upon termination and under prescribed circumstances, may be in the form of lump sums, installments, annuities or combinations thereof or employer securities. The Company bears the responsibility of all administrative expenses of the Plan, with the exception of certain expenses associated with certain Guaranteed Investment Contracts that expired in 1992.

At June 20, 1994, the market value of the shares of NL, Baroid/Dresser and Tremont stock held at December 31, 1993 was $2,546,672, $381,176 and $33,165, respectively.
