                       REPORT OF INDEPENDENT ACCOUNTANTS


To the Pension and Employee Benefits Committee of
NL Industries, Inc.:

      In our opinion,  the  accompanying  statements of net assets available for
benefits  and the  related  statements  of changes in net assets  available  for
benefits present fairly, in all material respects,  the net assets available for
benefits of the NL  Industries,  Inc.  Retirement  Savings  Plan (the "Plan") at
December 31, 1997 and 1998, and the changes in net assets available for benefits
for the years  then  ended in  conformity  with  generally  accepted  accounting
principles.  These  financial  statements are the  responsibility  of the Plan's
management;  our  responsibility  is to express  an  opinion on these  financial
statements  based on our audits.  We conducted our audits of these statements in
accordance with generally accepted auditing standards which 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,  assessing the accounting  principles used and significant estimates
made by management, and evaluating the overall financial statement presentation.
We believe that our audits provide a reasonable basis for the opinion  expressed
above.

      Our audits  were  conducted  for the  purpose of forming an opinion on the
basic financial  statements  taken as a whole. The  supplemental  schedules,  as
listed on the  accompanying  index,  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 fund  information  in the  statements  of net assets
available for benefits and the statements of changes in net assets available for
benefits is presented for purposes of additional analysis rather than to present
the net assets  available for plan benefits and changes in net assets  available
for benefits of each fund. These supplemental schedules and fund information are
the responsibility of the Plan's management. The supplemental schedules and fund
information have been subjected to the auditing procedures applied in the audits
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.

See accompanying notes to financial statements. F-10 NL INDUSTRIES, INC. RETIREMENT SAVINGS PLAN NOTES TO FINANCIAL STATEMENTS NOTE 1 - SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES: The financial statements of the NL Industries, Inc. Retirement Savings Plan (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. 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, if any, are accrued at the end of each year and are received 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. F-11 MANAGEMENT'S ESTIMATES The preparation of financial statements in conformity with generally accepted accounting principles requires management to make estimates and assumptions that affect the reported amounts of net assets available for benefits at the date of the financial statements, the changes in net assets available for benefits during the reporting period and, when applicable, the disclosures of contingent assets and liabilities at the date of the financial statements. Actual results could differ from those estimates. NOTE 2 - PLAN DESCRIPTION: The Plan's principal objective is to provide eligible employees of NL Industries, Inc. and its U.S. 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, 1998, there were 68 active participants (participants currently employed by the Company) and 635 total participants. Active participants may make basic contributions of between 0% 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. The specialty chemical business of Rheox, Inc., a wholly-owned subsidiary of the Company, was sold to Elementis plc in January 1998 and $18 million of the Plan's assets were distributed to Elementis America Inc. Rheox Inc. Retirement Savings Plan. 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 ($10,000 annual maximum for 1998). 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. The Company contributes a discretionary amount of matching contributions, determined annually, based upon the attainment of certain operating income target levels approved by the Management, Development and Compensation Committee of the Board of Directors of the Company. The employer match applies only to the employee's basic contributions. On March 31, 1996, the defined benefit plan for salaried employees of NL Industries, Inc. was amended and the pension benefits frozen for the majority of the Company's U.S. employees. Effective April 1, 1996, every employee who is eligible to participate in the Plan will receive an annual contribution to their investment account of 3% of their eligible compensation, subject to IRS limitations on eligible compensation, which currently is $160,000. The Company will make this contribution for each eligible employee regardless of whether the F-12 employee elects to otherwise participate in the Plan. This contribution is in addition to the Company's discretionary matching contribution described above. Employer contributions are fully vested upon death, retirement, or disability, as provided in the Plan. 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. Forfeitures were $4,068 in 1997 and $18,015 in 1998. 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. Merrill Lynch Trust Company ("Merrill Lynch" or "ML") 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, ----------------- 1997 1998 ---- ---- MFS EMERGING GROWTH FUND - CLASS A SHARES - managed with 121 62 the objective of providing long-term growth of capital by investing primarily in common stocks of small and medium- sized companies that are early in their life cycle but which have the potential to become major enterprises.

Contributions or transfers into the Halliburton/Tremont Stock Fund and the Merrill Lynch Global Holdings 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. Interfund transfers may be made daily, except that only one transfer per participant per quarter may affect amounts in the NL Stock Fund. Only one transfer is permitted out of the Halliburton/Tremont 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. Distributions may be in the form of lump sums, installments, annuities, or combinations thereof, or distributions of employer securities. The Company bears the responsibility of all administrative expenses of the Plan.
