REPORT OF INDEPENDENT ACCOUNTANTS To the Participants and Administrator of the Stillwater Mining Company 401(k) Plan and Trust In our opinion, the accompanying statements of net assets available for benefits and the related statement of changes in net assets available for benefits present fairly, in all material respects, the net assets available for benefits of the Stillwater Mining Company 401(k) Plan and Trust (the "Plan") at December 31, 1998 and 1997, and the changes in net assets available for benefits for the year ended December 31, 1998 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 of assets held for investment and reportable transactions 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 statement 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.

DESCRIPTION OF PLAN On June 1, 1993, Stillwater Mining Company (the "Company") established the Stillwater Mining Company 401(k) Plan and Trust (the "Plan"). The following description of the Plan provides general information only. Participants should refer to the Plan agreement for a more complete description of the Plan's provisions. GENERAL The Plan is a defined contribution plan covering all non-union employees of the Company and is subject to the provisions of the Employee Retirement Income Security Act ("ERISA"). Employees are eligible to participate in the Plan after completion of six consecutive months of service. PLAN AND TRUST ADMINISTRATION The administration of the Plan is the responsibility of the Company. The assets of the Plan are maintained in a trust fund administered under a trust agreement with Fidelity Management Trust Company (the "Trustee"). CONTRIBUTIONS Each participant has the option to make pre-tax "elective deferral contributions" to the Plan of not less than 1% nor more than 10% of eligible compensation. The Company contributes an amount equal to 200% of each participant's elective deferral contribution, up to 3% of the participant's compensation for the contribution period. Each participant also has the option to make after-tax contributions to the Plan of not less than 1% nor more than 10% of eligible compensation. The Company may make annual discretionary profit sharing contributions during each Plan year. Profit sharing contributions will be allocated to participants based on the ratio of each participant's eligible compensation to the total compensation paid to all eligible participants for the Plan year. PARTICIPANT ACCOUNTS Each participant's account is credited with the participant's contribution and allocation of (a) the Company's matching contribution, (b) Plan earnings and losses, and (c) discretionary contributions by the Company. Allocations of Plan earnings and losses are based on individual participant account balances in relation to the total of all participant account balances. VESTING Participants are at all times fully vested in their voluntary contributions plus actual earnings thereon. Vesting in employer contributions is based on years of continuous service. Participants become 100 percent vested after three years of service. During 1998, $19,874 of employer matching contributions were forfeited by employees who terminated before those amounts became vested. Forfeitures of terminated participants' nonvested accounts are retained in the Plan and used to reduce future employer matching contributions. 5 STILLWATER MINING COMPANY 401(k) PLAN AND TRUST NOTES TO FINANCIAL STATEMENTS (continued) PARTICIPANT LOANS Participants may obtain loans from the Plan of not less than $1,000 nor more than the lesser of one-half of their vested account balance or $50,000. Repayment of the loan must be made through payroll deduction over a five-year period, except for loans for the purchase of a participant's principal residence, which can be repaid over a ten-year period. PAYMENT OF BENEFITS At termination of service, participants receive a lump-sum amount equal to the vested value of his or her account. 2. SUMMARY OF ACCOUNTING POLICIES BASIS OF ACCOUNTING The Plan's financial statements are prepared on the accrual basis of accounting. APPRECIATION (DEPRECIATION) OF INVESTMENTS The Plan presents in the statement of changes in net assets the net appreciation (depreciation) in the fair value of its investments, which consists of the realized gains or losses and the unrealized appreciation (depreciation) of those investments. USE OF ESTIMATES The preparation of financial statements in conformity with generally accepted accounting principles requires management to make estimates and assumptions. Actual results could differ from those estimates. VALUATION OF INVESTMENTS AND INCOME RECOGNITION Plan investments are valued at fair value based on the market value or share price at the end of the year. Purchases and sales of investments are recorded on the trade date. Dividends are recorded as of the ex-dividend date. Interest income is recorded on the accrual basis. Participant loans are valued at principal amount, which approximates fair value. EXPENSES OF THE PLAN The Company reimburses the expenses incurred in the administration of the Plan. 3. INVESTMENTS Upon enrollment in the Plan, a participant may direct contributions to any of nine investment options managed by the Trustee. The investment alternatives include the Stillwater Mining Company Fund, the Growth and Income Portfolio, the Magellan Fund, the Government Securities Fund, the Asset Manager Portfolio, the Retirement Government Money Market Portfolio, the Low Priced Stock Fund, the Contrafund and the Diversified International Fund. As of December 31, 1998, the number of participants holding assets in the various investment options were as follows: 17 in the Stillwater Mining Company Fund, 149 in the Growth and Income Portfolio, 132 in the Magellan Fund, 46 in the Government Securities Fund, 76 in the Asset Manager Portfolio, 28 in the Retirement Government Money Market Portfolio, 19 in the Low Priced Stock Fund, 25 in the Contrafund and 14 in the Diversified International Fund. 6 STILLWATER MINING COMPANY 401(k) PLAN AND TRUST NOTES TO FINANCIAL STATEMENTS (continued) The following table represents units of participation and net asset value per unit for each investment option: 1998 1997 ---------------------------------- ---------------------------------- Units of Net Asset Units of Net Asset Participation Value Per Unit Participation Value Per Unit --------------- ---------------- --------------- ---------------- Stillwater Mining Company Fund 20,700.40 $ 23.90 - $ - Growth & Income Portfolio 82,390.24 45.84 76,058.65 38.10 Magellan Fund 25,760.98 120.82 24,250.21 95.27 Government Securities Fund 31,180.86 10.14 27,189.39 9.91 Asset Manager Portfolio 93,175.57 17.39 73,722.88 18.35 Retirement Gov't Money Market Portfolio 854,229.05 1.00 746,776.80 1.00 Low Priced Stock Fund 6,062.34 22.85 1,074.40 25.13 Contrafund 2,629.51 56.79 861.39 46.63 Diversified International Fund 1,792.74 17.72 584.33 16.13 4.

UNREALIZED APPRECIATION/DEPRECIATION OF INVESTMENTS Net unrealized appreciation of investments amounted to $2,670,352 and $1,532,186 at December 31, 1998 and 1997, respectively. The change in net unrealized appreciation resulted in a Plan gain of $1,138,166 in 1998. 6. PLAN TERMINATION Although it has not expressed any intent to do so, the Company has the right under the Plan to discontinue its contributions at any time and to terminate the Plan subject to the provisions of ERISA. However, no such action may deprive any participant or beneficiary under the Plan of any vested right. 7. TAX STATUS The Company has obtained a favorable determination letter dated May 18, 1995 from the Internal Revenue Service as to the qualified status of the Plan under Section 401(a) of the Internal Revenue Code. The Company is of the opinion that the Plan has operated in conformity with the Internal Revenue Code and will continue to fulfill the requirements of a qualified plan and that the trust which forms part of the plan is not subject to tax. Accordingly, no federal or state income taxes have been provided. 8 STILLWATER MINING COMPANY 401(k) PLAN AND TRUST SCHEDULE OF ASSETS HELD FOR INVESTMENT DECEMBER 31, 1998 SCHEDULE I COST OF CURRENT ISSUER DESCRIPTION OF INVESTMENT ASSET VALUE Stillwater Mining Company (a) Stillwater Mining Company Fund - Common Stock $ 435,815 $ 494,700 Fidelity Investments (b) Growth and Income Portfolio 2,450,616 3,776,769 Magellan Fund 1,974,975 3,112,441 Government Securities Fund 311,578 316,174 Asset Manager Portfolio 1,478,870 1,620,323 Retirement Government Money Market Portfolio 854,229 854,229 Low Priced Stock Fund 147,288 138,525 Contrafund 139,804 149,330 Diversified International Fund 30,731 31,767 Participants Participant loans; interest rates ranging from 8.0% to 10.0% 341,034 341,034 - ----------- (a) Party-in-interest.
