INDEPENDENT AUDITORS' REPORT

Administrative Committee
   Interim Services Inc.
   401(k) Benefit Plan
Fort Lauderdale, Florida:

We have audited the accompanying statements of net assets available for benefits
of Interim Services Inc. 401(k) Benefit Plan (the "Plan") as of December 31,
1998 and 1997, and the related statements of changes in net assets available for
benefits for the years then ended. 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, such financial statements present fairly, in all material
respects, the net assets available for benefits of the Plan as of December 31,
1998 and 1997, and the changes in net assets available for 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 accompanying supplemental schedules
of (1) assets held for investment purposes as of December 31, 1998 and (2)
reportable transactions for the year ended December 31, 1998 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 schedules are the
responsibility of the Plan's management. Such schedules have been subjected to
the auditing procedures applied in our audit of the basic 1998 financial
statements and, in our opinion, are fairly stated in all material respects when
considered in relation to the basic financial statements taken as a whole.

INTERIM SERVICES INC.
401(k) BENEFIT PLAN

NOTES TO FINANCIAL STATEMENTS
YEARS ENDED DECEMBER 31, 1998 AND 1997
- ------------------------------------------------------------------------------

1.    SIGNIFICANT ACCOUNTING POLICIES

      BASIS OF ACCOUNTING - The financial statements of the Interim Services
      Inc. 401(k) Benefit Plan (the "Plan") have been prepared on the accrual
      basis of accounting.

      USE OF ESTIMATES - The preparation of financial statements in conformity
      with generally accepted accounting principles requires management to make
      estimates and assumptions that affect certain reported amounts and
      disclosures. Actual results could differ from those estimates.

      INVESTMENTS - Investments are stated at fair value, determined using
      quoted market prices. Net appreciation or depreciation in fair value of
      investments is determined by using the beginning of the year values or
      purchase price if acquired during the year. Participant loans receivable
      bear a prime interest rate and are collectible over a period not to exceed
      five years.

      FORFEITED ACCOUNTS - For the years ended December 31, 1998 and 1997,
      forfeitures on nonvested accounts totaled $183,641 and $216,301,
      respectively. Effective April 1, 1997, forfeitures are retained in the
      Plan to be used to offset future employer contributions.

      DISCLOSURE REGARDING FINANCIAL INSTRUMENTS - Investments are stated at
      fair value, determined using quoted market prices. The carrying amount of
      participant loans approximate fair value because the interest rates on
      these instruments change with market interest rates.

      NEW ACCOUNTING PRONOUNCEMENTS - In June 1998, the FASB issued SFAS No.
      133, ACCOUNTING FOR DERIVATIVE INSTRUMENTS AND HEDGING ACTIVITIES. Among
      other provisions, SFAS No. 133 establishes accounting and reporting
      standards for derivative instruments and for hedging activities. It also
      requires that an entity recognize all derivatives as either assets or
      liabilities in the statement of financial position and measure those
      instruments at fair value. SFAS No. 133 is effective for financial
      statements for fiscal years beginning after July 1, 2000. The Plan Sponsor
      has not determined what effects, if any, the adoption of SFAS No. 133 will
      have on the Plan's financial statements.

2.    DESCRIPTION OF THE PLAN

      The Plan is a defined contribution plan sponsored by Interim Services Inc.
      ("Interim"). Effective April 1, 1997, non-highly compensated employees are
      eligible for participation under the Plan after completing 90 days of
      service (previously 1,000 hours and 12 months of service were required).
      Employees' contributions (made on a pre-tax basis, equal to not less than
      1 percent nor more than 15 percent of an employee's compensation) and
      actual earnings thereon are fully vested and nonforfeitable. Prior to
      April 1, 1997, employee contributions were limited to 2 percent to
      10 percent of pre-tax compensation. Under the previous plan provisions,
      employer contributions amounts vested on a graduated scale from 2 to 6
      years of service, becoming 100% vested at the end of six years or upon
      death, permanent disability or retirement at age 65. Subsequent to
      April 1, 1997, employer contributions (at present equal to 25 percent,
      with the possibility of an additional discretionary


                                       -4-


      match, up to 25 percent paid upon approval by the Board of Directors, of
      the sum of an employee's compensation reduction on the first 6 percent
      for the plan year) vest on a graduated scale from 1 to 5 years of service
      and become 100% vested at the end of five years or upon death, permanent
      disability or retirement at age 65. Effective January 1, 1992, employee
      after-tax contributions may no longer be made to the Plan. Any such
      contributions made prior to such date are fully vested and nonforfeitable.
      Plan earnings are allocated to individual accounts based on the
      participant's beginning balance as a percentage of the Plan's total
      beginning balance. Loans are limited to the lesser of $50,000 or 50% of
      the participant's vested account balance.

      Plan participants who leave Interim as a result of termination, retirement
      or permanent disability may elect to receive their entire vested account
      in a lump-sum, a rollover into another qualified plan, or if the balance
      exceeds $5,000, the participant may retain their vested balance in the
      Plan. Contributions will remain in the Plan and continue to earn interest
      based on the investment fund of the participant's choice until their
      entitlement is withdrawn or rolled over into another qualified plan.
      Participants of certain plans, which were merged into the Plan on
      April 1, 1997, may receive annuity payouts.

      Although Interim has not expressed any intent to do so, it has the right
      to discontinue its contributions at any time and to terminate the Plan
      subject to the provisions set forth in the Plan and under ERISA. In the
      event that the Plan should be terminated, all Plan assets shall be
      allocated to the participants as described in the full text of the Plan.
      Effective April 1, 1997, administrative expenses are charged to Plan
      participant accounts. The plan sponsor directly pays certain audit and
      legal expenses for the Plan.

      The following investment funds represent the available options which the
      participants may elect to use:

4.    PLAN COMMITTEES AND TRUSTEE

      The Plan provides for selection of an Administrative Committee, a Plan
      Administrator and a Trustee by the Board of Directors of Interim. The
      Administrative Committee is responsible for the general administration of
      the Plan, the interpretation of its provisions and is responsible for the
      reporting and disclosure requirements under ERISA. Effective September 1,
      1998, T. Rowe Price was established as Trustee of the Plan and as the
      Plan's Administrator.

5.    PLAN TAX STATUS

      The Plan intended to be qualified under Section 401(a) of the Internal
      Revenue Code of 1986 (the "Code") and is intended to be exempt from
      taxation under Section 501(a) of the Code. The Plan received a favorable
      IRS determination letter dated July 23, 1996 and a new IRS determination
      request has been filed. The Plan has been amended since receiving the
      determination letter. However, the Plan Sponsor believes that the Plan
      is currently designed and being operated in compliance with the
      applicable requirements of the Code and the related trust was tax-exempt
      as of the financial statement date. Therefore, no provision for income
      taxes has been included in the Plan's financial statements.
