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 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 management, 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 benefits of the Plan as of December 31, 1997 and 1996, and the changes in net assets available for benefits for the years then ended in conformity with generally accepted accounting principles. Our audits were performed for the purpose of forming an opinion on the basic financial statements taken as a whole. The supplemental schedules listed on page 1 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 benefits and changes in net assets available for benefits of each fund. 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. /s/ Coopers & Lybrand L.L.P.

----------- 1. MAJOR FEATURES OF THE PLAN: General The Quaker State Corporation Thrift and Stock Purchase Plan (the Plan) is a defined contribution and profit sharing plan available to eligible employees of Quaker State Corporation and certain of its subsidiaries (Quaker State or the Company) who have reached age 21. The Plan is subject to the provisions of the Employee Retirement Income Security Act of 1974 (ERISA). The Organization and Compensation Committee of the Quaker State Board of Directors administers the Plan. Reference should be made to the Quaker State Corporation Thrift and Stock Purchase Plan Summary Plan Description and Prospectus for a detailed description of the Plan including eligibility, vesting, employee and Company contributions, investment options, withdrawals, borrowings by participants and termination of the Plan. Investment Options Effective February 1, 1997, certain funds managed by Fidelity Investments, a registered investment advisor, became the investment options of the Plan. All Company contributions are invested in the Quaker State Stock Fund; however, participants may select any one or more of the funds for their contributions. The investment options are as follows: o Fidelity Retirement Money Market Portfolio - A fund primarily invested in short-term money market securities of U.S. and foreign issuers. o Fidelity Investment Grade Bond Fund - A fund that invests at least 65% of its portfolio in investment-grade fixed-income securities including a broad range of corporate debt securities that are investment grade. o Fidelity Puritan Fund - A balanced fund primarily invested in a combination of equity and fixed income securities. o Fidelity Growth & Income Portfolio - A growth and income fund invested primarily in domestic securities focusing on those that pay current dividends and offer potential growth of earnings. o Fidelity Contrafund - A growth fund which seeks long-term capital appreciation by investing mainly in the securities of companies believed to be undervalued. o Fidelity Low-Priced Stock Fund - A growth fund primarily invested in domestic and foreign low-priced stocks that may be undervalued. o Fidelity Magellan Fund - A growth fund primarily invested in securities of companies with above-average growth potential. o Fidelity Diversified International Fund - An international fund invested primarily in equity securities of companies outside the United States. o Quaker State Stock Fund - A fund invested primarily in Quaker State common stock with a small amount invested in short-term instruments. Prior to February 1, 1997, only four funds were available for investment. Fund A, the Income Fund, was composed of Compass Capital Money Market funds and bonds or other obligations issued by the U.S. Government. Fund B was the Compass Capital Intermediate Government Portfolio, a registered investment company, comprised of a portfolio of fixed income securities. Fund C, the Quaker State Stock Fund, is composed of Quaker State capital stock. Fund D was the Compass Capital Index Equity Portfolio, a registered investment company, comprised of a diversified portfolio of corporate stocks. Participant directed and non-participant directed funds included in Fund C at December 31, 1996 were as follows: Units Dollars ------- ---------- Participant directed 171,903 $6,337,600 Non-participant directed 203,340 7,496,620 9 14 NOTES TO FINANCIAL STATEMENTS, Continued ----------- 1. MAJOR FEATURES OF THE PLAN, continued Investments in Fund C represent shares of Quaker State capital stock, and, therefore, transactions within Fund C also qualify as exempt party-in-interest transactions. In 1996, the recordkeeper for the Plan was William M. Mercer Company, Inc. On February 1, 1997, the Plan changed recordkeeper to Fidelity Institutional Retirement Services Company and the trustee to Fidelity Management Trust Company. Contributions Under the Plan, participants may elect to make contributions on a tax-deferred basis in the form of a salary reduction (Tax-Deferred Contributions) up to the lesser of 15% of their compensation or $10,000 (as adjusted annually by the Internal Revenue Service). In addition, employees may elect to make contributions on an after-tax basis in the form of a payroll deduction (Thrift Contributions) of up to 6% of their compensation; however, the sum of the Thrift Contributions and the Tax-Deferred Contributions cannot exceed 15% of the participant's compensation. For contribution purposes, not more than $160,000 of a participant's compensation (as adjusted annually by the Internal Revenue Service) can be taken into account for any one calendar year. Subject to limitations, the Company will make contributions (Regular Company Contributions) in an amount equal to 50% of a participant's total contributions paid each pay date up to a maximum of 3% of that participant's compensation. In addition, the Plan accepts rollover contributions from employees' former employer qualified plans and conduit IRAs. Vesting Participants are fully vested in their contributions plus actual earnings thereon. Participants are also fully vested in Regular Company Contributions and Company Profit Sharing Contributions. Participant Accounts and Benefit Payments An account is maintained for each participant, which is credited with the participant's contributions and allocation of (a) the Company's contributions, and (b) Plan earnings. Allocations are based on participant contributions, other than rollover contributions, or account balances, as defined by the Plan. The benefit to which a participant is entitled is the benefit that can be provided from that participant's account. As of December 31, 1997 and 1996, there were 2,833 and 1,966 participants in the Plan, respectively. Amendments In February 1997, the Plan was amended to: (1) change the minimum contribution percentage to each fund from 10% to 1% increments; (2) make immediate participation available to new employees over 21 years of age; (3) make Plan accounting and transaction processing daily; (4) increase the number of investment options available under the Plan to a maximum of ten investments, one of which would be Quaker State capital stock; (5) change the method of calculating the interest rate on loans; (6) make other changes necessary to comply with the new recordkeeper and trustee systems; and (7) make amendments required by the Small Business Job Protection Act of 1996. 2. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES: Basis of Accounting The financial statements of the Plan are prepared under the accrual method of accounting. 10 15 NOTES TO FINANCIAL STATEMENTS, Continued ----------- 2. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES, continued: Investments Investments are carried at fair value in the accompanying financial statements. Investments in Quaker State capital stock are valued at the closing price on the last business day of the period. Investments in money market accounts are carried at cost which approximates market. Registered investment companies are valued at market determined by quoted market prices. Participant loans receivable are valued at cost which approximates market. Purchases and sales of Quaker State capital stock are reflected on a trade-date basis. Gains and losses are based on average cost for Quaker State capital stock. Dividend income is recorded on the ex-dividend date. Interest income is recorded as earned. The Plan presents in the Statement of Changes in Net Assets Available for 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 Quaker State capital stock and net increase (decrease) in the value of the Plan's interest in mutual funds. Other Administrative expenses, including trustee, legal, auditing and other fees, are paid by Quaker State and, therefore, are not expenses of the Plan. The preparation of financial statements requires the plan administrator to make estimates and assumptions that affect the reported amounts of net assets available for benefits at the date of the financial statements and amounts included as changes in net assets available for benefits during the reporting period. Actual results could differ from those estimates. The Plan provides for various investment options including investment securities. Investment securities are exposed to various risks, such as interest rate, market, and credit risks. Due to the level of risk associated with certain investment securities, it is at least reasonably possible that changes in the values of the investment securities will occur in the near term and that such changes could materially affect the amounts reported in the Statement of Net Assets Available for Plan Benefits. 3. INVESTMENTS: Investments that represent 5% or more of the Plan's net assets are: FUNDS 1997 1996 ----- ---- ---- Fidelity Magellan Fund $ 2,237,095 -- Fidelity Contrafund 2,699,960 -- Fidelity Growth & Income Fund 8,536,472 -- Fidelity Low-Priced Stock Fund 2,171,905 -- Fidelity Retirement Money Market Fund 2,573,912 -- Compass Capital Money Market -- $ 2,378,757 Compass Capital Intermediate Government Portfolio -- 2,300,053 Quaker State Corporation Stock 13,802,068 13,535,662 Compass Capital Index Equity Portfolio -- 5,711,006 Participant Loans 1,953,633 1,500,938 11 16 NOTES TO FINANCIAL STATEMENTS, Continued ----------- 4. PARTICIPANT LOANS: Participants are permitted to borrow against all or a portion of their Tax-Deferred Contribution and Company Profit-Sharing Contribution units within prescribed limitations and pursuant to nondiscriminatory rules established by the Committee. Loan transactions are treated as a transfer to (from) the applicable investment fund from (to) the Employee Loan Account. Each loan is to be repaid over a period not to exceed five years or ten years for certain loans related to a participant's primary residence. The interest rate applied to a current loan is the rate set by the Compensation Committee from time to time determined by periodically comparing rates at various banks. Principal and interest payments are generally made through payroll deductions and are credited to the participant's individual Plan account(s). Loans totaling $1,275,409 and $756,703 were made from the Plan, and repayments, including interest of $134,154 and $118,203, totaling $956,868 and $1,053,892 were received by the Plan during the years ended December 31, 1997 and 1996, respectively. As of December 31, 1997, there were 852 loans to participants, maturing from 1998 to 2007, with interest rates ranging between 7% and 10.5%. 5. FEDERAL INCOME TAXES: The Internal Revenue Service has determined and most recently informed the Plan by letter dated January 27, 1998, that the Plan is qualified and the Trust established under the Plan is tax-exempt, under the appropriate sections of the Internal Revenue Code. Accordingly, no provision has been made for federal income taxes. Certain prior and any subsequent amendments to the Plan are subject to Internal Revenue Service review and approval. The Plan administrator and its legal counsel do not anticipate that such changes will affect the qualified and tax-exempt status of the Plan and Trust, respectively. Thrift Contributions are included in the participant's income in the year the payroll deductions are made and are not deductible by the participant for federal income tax purposes. Tax-Deferred Contributions are not included in the participant's income for federal income tax purposes and, therefore, are not subject to federal income tax or withholding at the time of contribution. Company contributions and earnings reinvested into the various funds are not taxable to the participant until distribution. 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. 7. MERGER OF THE QUAKER STATE EMPLOYEE STOCK OWNERSHIP PLAN AND OTHER PLANS: Effective December 31, 1997, the Quaker State Employee Stock Ownership Plan (ESOP) was merged into the Plan.
