4 4 REPORT OF INDEPENDENT ACCOUNTANTS To the Participants and Administrator of Kelly Retirement Plus 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 Kelly Retirement Plus (the "Plan") at December 31, 1999 and December 31, 1998, and the changes in net assets available for benefits for the year ended December 31, 1999, in conformity with accounting principles generally accepted in the United States. 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 auditing standards generally accepted in the United States, 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 Purposes as of December 31, 1999 and of Reportable Transactions for the year then ended 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. These supplemental schedules are the responsibility of the Plan's management. The supplemental schedules 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/ PricewaterhouseCoopers LLP - ------------------------------- PRICEWATERHOUSECOOPERS LLP DETROIT, MICHIGAN JUNE 20, 2000

7 7 KELLY RETIREMENT PLUS NOTES TO FINANCIAL STATEMENTS (In thousands of dollars) - -------------------------------------------------------------------------------- 1. ACCOUNTING PRINCIPLES AND PRACTICES BASIS OF ACCOUNTING The financial statements of Kelly Retirement Plus (the Plan) have been prepared on the accrual basis in accordance with generally accepted accounting principles and, as such, include amounts based on management's best estimates. Actual results could differ from those estimates. INVESTMENT VALUATION AND INCOME RECOGNITION Plan investments are stated at fair value as of the last day of the Plan year. The Plan's mutual fund investments are valued based on quoted market prices. The Bank One Stable Asset Income Fund is valued at the unit price, as determined by Bank One, the plan trustee, which represents fair value. Employer contributions are recorded in the period during which they were approved by the Board of Directors of Kelly Services, Inc. (the Company). Employee contributions are recorded in the period during which the Company makes payroll deductions from the Plan participants' earnings; matching company contributions are recorded in the same period. Administrative expenses incurred shall be paid by the Plan to the extent not paid by the Company. PAYMENT OF BENEFITS Benefits are recorded when paid. RISKS AND UNCERTAINTIES The Plan provides for various investment options in mutual funds that hold stocks, bonds, fixed income securities and other 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 investment securities will occur in the near term, and that such changes could materially affect participants' account balances and the amounts reported in the statement of net assets available for benefits.

PLAN DESCRIPTION The following description of the Plan provides only general information. Participants should refer to the Plan agreement for a more complete description of the Plan's provisions. GENERAL The Plan, established on January 2, 1989 and amended and restated effective January 1, 1990 and January 1, 1993, provides benefits to eligible employees according to the provisions of the Plan agreement. All eligible employees, as defined by the Plan, are eligible to participate upon completion of one year of service and attainment of age 21. The Plan is subject to the provisions of the Employee Retirement Income Security Act of 1974 (ERISA). CONTRIBUTIONS The Plan consists of two parts: Part I is a defined contribution plan, under which the Company may make a discretionary contribution on behalf of all participants in an amount to be determined by the Company. The contribution to the Plan for 1999 represented 2% of participants' eligible wages for the year. Part II is a Section 401(k) savings plan, which enables participants to contribute to the Plan using pre-tax dollars, with the Company matching $.50 per dollar of their contribution up to 4% of eligible pay.

11 11 KELLY RETIREMENT PLUS NOTES TO FINANCIAL STATEMENTS (In thousands of dollars) - -------------------------------------------------------------------------------- 4. PLAN DESCRIPTION (CONTINUED) PARTICIPANT ACCOUNTS Each participant's account is credited with the participant's contribution, the Company's matching contribution, an allocation of the Company's discretionary contribution and Plan earnings. Earnings are allocated by fund based on the ratio of a participant's account invested in a particular fund to all participants' investments in that fund. The benefit to which a participant is entitled is the benefit that can be provided from the participant's vested account. PLAN ADMINISTRATION The Plan is administered by a committee appointed by the Board of Directors of the Company. This committee is composed of the Executive Vice President and Chief Financial Officer and the Senior Vice Presidents in charge of Human Resources and Legal and serves at the pleasure of the Board. INVESTMENT OPTIONS Part I contributions are invested by the trustee as directed by the committee and are held in the One Group Investor Growth & Income Fund, formerly in the Pegasus Managed Assets Balanced Fund. Rollover contributions from other qualified plans are deposited into the Contribution Money Market Fund until allocated to participant elected investment options. Part II contributions are directed by the participant among any of the following funds held with the trustee (effective 4/1/99, the Plan's investments in Pegasus Funds were liquidated and all amounts were invested in the comparable One Group Mutual Funds): ONE GROUP EQUITY INDEX FUND (FORMERLY PEGASUS EQUITY INDEX FUND) - This fund seeks investment results that correspond to the aggregate price and dividend performance of the securities in the Standard & Poor's 500 Composite Stock Price Index of common stocks. ONE GROUP INTERMEDIATE BOND FUND (FORMERLY PEGASUS INTERMEDIATE BOND FUND) - This fund seeks to maximize total rate of return while providing relative stability of principal by investing predominantly in both domestic and foreign intermediate-term debt securities. The weighted average maturity of bonds in the fund is between three and six years. ONE GROUP DIVERSIFIED MID CAP FUND (FORMERLY PEGASUS MID CAP OPPORTUNITY FUND) - This fund seeks long-term capital growth by investing primarily in equity securities of companies with intermediate capitalizations. ONE GROUP INVESTOR GROWTH & INCOME FUND (FORMERLY PEGASUS MANAGED ASSETS BALANCED FUND) - This fund seeks long-term capital appreciation and growth of income by investing primarily in a diversified group of One Group mutual funds which invest primarily in equity securities. ONE GROUP MID CAP VALUE FUND (FORMERLY PEGASUS INTRINSIC VALUE FUND) - This fund seeks capital appreciation with the secondary goal of achieving current income by investing primarily in equity securities. ONE GROUP LARGE CAP GROWTH FUND (FORMERLY PEGASUS GROWTH FUND) - This fund seeks to provide current income while seeking capital growth by investing primarily in common stocks of U.S. companies with dominant market position in their industries and that have a record of paying regular dividends on common stock or have the potential of capital appreciation.

12 12 KELLY RETIREMENT PLUS NOTES TO FINANCIAL STATEMENTS (In thousands of dollars) - -------------------------------------------------------------------------------- 4. PLAN DESCRIPTION (CONTINUED) STABLE ASSET INCOME FUND - This fund provides a portfolio of various types of investment contracts issued by insurance companies, banks and other financial institutions. It provides price and income stability and reduces volatility. KELLY STOCK FUND - This fund allows for investment in the Company's Class A non-voting common stock. A portion of the investments are held in the Fidelity Cash Portfolio money market fund. VESTING Participants become fully vested in Company contributions upon attainment of age sixty-five or completion of five years of service, whichever occurs first. The first year of service begins at the later of age 18 or date of hire. Participant contributions are 100% vested immediately. The value of the vested portion of participants' accounts is payable to the participant upon retirement, total and permanent disability, death or termination of employment in a lump-sum distribution. If the vested portion of a participant's account exceeds five thousand dollars (or such other amount to be prescribed in regulations by the Secretary of the Treasury or his delegate), the participant may defer receipt of the distribution until any time prior to or upon attaining age 70-1/2. Vested accounts five thousand dollars or less are paid in an immediate lump-sum distribution. PARTICIPANT FORFEITURES Pursuant to the Plan agreement, participant forfeitures can be used by the Plan to (1) restore the participant's account in the event of rehire or (2) reduce the employer Part I profit-sharing or matching contribution. The Plan administrator offset the employer Part I profit-sharing contribution with the forfeiture balance of $633 and $270 at December 31, 1999 and 1998, respectively, by allocating these amounts among the participant accounts. 5. PRIORITIES ON PLAN TERMINATION In the event of termination of the Plan, the accounts of all participants shall become fully vested and shall be distributed to the members simultaneously with all participants receiving full value of their accounts on the date of such distribution.
