                     1997 STOCK PURCHASE ASSISTANCE PLAN
                                       


1.   PURPOSE

     The Board of Directors of Interim Services Inc. (the "Company") has 
established Company stock ownership guidelines for Company executives (the 
"Guidelines") as a means of aligning the interests of Company executives and 
stockholders. The purpose of the Interim Services Inc. 1997 Stock Purchase 
Assistance Plan (the "Plan") is to facilitate investment by Company 
executives in shares of Company stock at levels at least sufficient to 
satisfy the Guidelines.

2.   DEFINITIONS

     (a)   "Board" means the Board of Directors of the Company.

     (b)   "Change in Control" means the occurrence of any one of the 
following events: (i) any person, entity or group of persons or entities 
acting in concert (other than a subsidiary of the Company), including any 
person as defined in Section 13(d)(3) of the Exchange Act, becoming the 
beneficial owner, as defined in Rule 13d-3 of the Exchange Act, directly or 
indirectly, of more than twenty-five percent (25%) of the total combined 
voting power of all classes of capital stock of the Company ordinarily 
entitled to vote for the election of directors of the Company, (ii) the sale 
of all or substantially all of the property or assets of the Company and its 
subsidiaries, (iii) the consolidation or merger of the Company with another 
corporation, other than with any subsidiary of the Company, the consummation 
of which would result in the occurrence of an event described in clause (i) 
above, or (iv) a change in the Board occurring with the result that the 
members of the Board on the effective date hereof (the "Incumbent Directors") 
no longer constitute a majority of such Board, provided that any person 
becoming a director whose election or nomination for election was supported 
by a majority of the Incumbent Directors shall be considered an Incumbent 
Director for purposes hereof.

     (c)   "Compensation Committee" means the Compensation Committee of the 
Board.

     (d)   "Company" means Interim Services Inc., a Delaware corporation.

     (e)   "Guidelines" means the stock ownership guidelines established by 
the Board, as the same may be amended from time to time.

<PAGE>

     (f)   "Participant" means an employee of the Company or any subsidiary 
of the Company who is selected by the Committee to participate in the Plan 
pursuant to Section 3 hereof.

     (g)   "Plan" means the Interim Services Inc. 1997 Stock Purchase 
Assistance Plan.

     (h)   "Plan Administrative Committee" means the Plan Administrative 
Committee appointed by the Board to administer the Company's employee benefit 
plans.

     (i)   "Repayment Obligation" shall mean the obligation of a Participant 
to repay Interest Payments under Section 5(c) or 6(a).

     (j)   "Stock" means the common stock of the Company, par value $.01 per 
share.

     (k)   "Stock Acquisition Loan" means an individually secured loan 
negotiated with the Company's assistance with an approved lending institution 
on behalf of a Participant. A Stock Acquisition Loan shall be obtained by the 
Participant on the basis of his or her individual credit worthiness and shall 
be guaranteed by the Company. The maximum term for a Stock Acquisition Loan 
shall be seven (7) years.

3.   PARTICIPATION

     The Compensation Committee shall designate those employees of the 
Company who shall be eligible to participate in the Plan.

4.   STOCK ACQUISITION

     (a)   The Plan Administrative Committee shall designate the 
participation level for each Participant through the table set forth in 
Appendix A, as the same may be amended from time to time. Under the Plan, 
each Participant is eligible to acquire Stock up to the participation level 
designated in Appendix A.

     (b)   To facilitate the Participant's acquisition of Stock under the 
Plan, the Company shall use reasonable efforts to provide each Participant 
with access to Stock Acquisition Loans, the proceeds of which shall be used 
for such Stock acquisition. Subject to any lending requirements imposed by an 
outside lender through which Stock Acquisition Loans are obtained, a 
Participant may take out additional Stock Acquisition Loans from time to time 
and have multiple Stock Acquisition Loans outstanding at any time.

5.   STOCK OWNERSHIP INCENTIVE PAYMENTS

     (a)   During the term of any Stock Acquisition Loan, the Company shall 
reimburse each Participant the amount of interest paid by the Participant on 
such Stock Acquisition Loan. Such reimbursements ("Interest Payments") shall 
be made on a quarterly basis. During the first

                                      -2-

<PAGE>

three years that any Stock Acquisition Loan is outstanding, the Interest 
Payments shall also include a tax equalization "gross up" intended to 
approximate the participant's additional federal income tax liability 
(assuming a 31 percent marginal tax rate) resulting from the Interest 
Payment. The total Interest Payment, including the gross-up amount (which 
shall be calculated without reference to the Participant's actual federal 
income tax rate or liability) shall be equal to the amount obtained by 
dividing the total amount of interest paid by the Participant during the 
quarter by .69. For example, if the total interest paid by the Participant 
during a quarter is $600, the Interest Payment, including the gross up 
amount, would be $600 divided by .69, or $869.57.

     (b)   The Plan Administrative Committee may authorize additional cash 
advances to a Participant if, upon a recommendation by the Plan 
Administrative Committee, the Compensation Committee determines such advances 
are necessary to avoid a sale or other disposition of Stock by such 
Participant due to a margin call, or to prevent a sale or disposition of the 
Stock by such Participant if, in the Plan Administrative Committee's 
judgment, such disposition would be detrimental to the Company or would 
adversely affect shareholder value.

     (c)   In the case of a Participant who exercises a nonqualified option 
to acquire Stock ("NSO") in order to satisfy the stock ownership levels 
specified in the Guidelines, the Compensation Committee may authorize 
additional cash payments to such Participant to compensate the Participant 
for the approximate difference between (i) the estimated federal income tax 
liability incurred by the participant by reason of such NSO exercise 
(assuming a 31 percent marginal tax rate) and (ii) the tax liability the 
Participant would have incurred if the difference between the exercise price 
of the NSO and the fair market value of the Stock subject to the NSO on the 
option exercise date (the "Spread") were taxed at a federal income tax rate 
applicable to long-term capital gain of 20 percent (such payment being 
referred to as the "Spread Reimbursement"). The Spread Reimbursement upon the 
exercise of a nonqualified option shall be calculated by multiplying the 
amount of the Spread by 11 percent. Such payments may include a "gross-up" 
sufficient to offset the Participant's federal income tax liability incurred 
on the receipt of the Spread Reimbursement, as determined by the Compensation 
Committee in its sole and absolute discretion. Unless otherwise specified by 
the Compensation Committee, any Spread Reimbursement paid to the Participant 
under this Section 5(c) shall be subject to a Repayment Obligation in 
accordance with the provisions of Section 6 in the same manner applicable to 
Interest Payments described in Section 6(a).

     (d)   Notwithstanding any contrary provision of this Plan, unless 
otherwise approved by the Compensation Committee, no Participant shall be 
eligible to receive Interest Payments or tax gross-up payments with respect 
to any Stock Acquisition Loan if (i) the proceeds of such loan are used to 
purchase Shares of Stock on the open market or in a private sale and (ii) the 
Participant had, on the date of such Stock acquisition, presently exercisable 
employee stock options which remain unexercised.

6.   PARTICIPANT REPAYMENT OBLIGATIONS

     (a)   Following the third anniversary of any Stock Acquisition Loan and 
prior to the seventh anniversary of such Stock Acquisition Loan, the Company 
will continue to make Interest Payments (without the "gross up" for federal 
income tax) to the Participant in accordance with Section 5 hereof; provided, 
however that the Participant shall be obligated to repay such Interest 
Payments to the Company for periods after the third anniversary of the Stock 
Acquisition Loan term.

     (b)   The repayment obligation of a Participant ("Repayment Obligation") 
shall be evidenced by a writing signed by the Participant and by the 
execution of a negotiable promissory note. Any Repayment Obligation shall 
bear interest at a rate, adjusted each calendar quarter, equal to the prime 
rate as published in the WALL STREET JOURNAL on the last business day of the 
preceding calendar quarter and shall be secured by a second priority security 
interest in the Participant's Stock acquired with the proceeds of the Stock 
Acquisition Loan.

     (c)   Payment of a Repayment Obligation shall be required in full on the 
earlier of (i) the Participant's termination of employment with the Company, 
(ii) the seventh anniversary of the corresponding Stock Acquisition Loan or 
(iii) subject to the limitation of Section 6(d), the sale or other 
disposition of the Stock if such sale or disposition causes the Participant's 
Stock ownership level to fall below the participation level designated in the 
Guidelines.

     (d)   Notwithstanding the provisions of Subsection (c) above, any 
acceleration of a Repayment Obligation on account of a sale or other 
disposition pursuant to Subsection 6(c)(ii) shall be limited to the lesser of 
(i) any gain from such sale or disposition (net of any commissions) and (ii) 
the Participant's Repayment Obligation at the time of the sale or disposition 
multiplied by the ratio of the number of shares of Stock sold or disposed of 
by the Participant to the total number of shares of Stock held by the 
Participant prior to such sale or disposition. Any portion of a Repayment 
Obligation not accelerated as a result of the limitation described in the 
preceding sentence shall continue to be repayable in accordance with the 
provisions of Section 6(c).

     As an example of the manner in which this provision is intended to 
operate, assume a Participant ("A") has a participation level under the 
Guidelines of 1,000 shares of Stock. A acquires the 1,000 shares of Stock 
with the proceeds of a 7-year Stock Acquisition Loan. In Year 4, A sells 700 
shares (thus, falling below his designated participation level of 1,000 
shares) at a gain of $200 (net of commissions). At the time of the sale, A 
had a Repayment Obligation of $400 related to interest on his Stock 
Acquisition Loan. Because A's sale of 700 shares is prior to the end of the 
Stock Acquisition Loan term, A is required to pay the Company $200. Since A's 
gain on the sale of the 700 shares (i.e., $200) is less than A's 
proportionate share of his Repayment Obligation related to those 700 shares 
(i.e., $280 -- $400 x 700 shares/1,000 shares = $280), A must pay $200 to the 
Company pursuant to Section 6(d).

     (e)   Notwithstanding anything to the contrary contained herein, 
Participant's Repayment Obligations shall terminate upon Participant's 
termination of employment with the Company if such termination occurs within 
twelve (12) months after a Change in Control of the

                                      -4-

<PAGE>

Company and such termination is (a) by the Company, or (b) by the Participant 
for "good reason." For the purposes of this paragraph, "good reason" shall 
mean either a material reduction by the Company in the Participant's duties 
and responsibilities, or a material reduction in the Participant's base 
compensation. Upon any termination of employment with the Company by the 
Participant, the Company's obligations to make further Interest Payments to 
such Participant shall terminate immediately. For purposes of this Section 
6(e), employment with a subsidiary of the Company shall be deemed to be 
employment with the Company.

7.   TERMINATION AND AMENDMENT

     The Plan is completely voluntary on the part of the Company and neither 
its existence nor its continuation shall be construed as creating any 
contractual right to or obligation for its continued existence, nor shall the 
existence of the Plan or participation therein be deemed to modify or 
otherwise affect a Participant's continued employment with the Company. The 
Company reserves the right at any time to modify or terminate the Plan by 
action approved in writing by the Board or its delegatee, provided that such 
modification or termination shall not affect the rights and obligations of 
Participants and the Company under any then outstanding Stock Acquisition 
Loans.

8.   ADMINISTRATION OF THE PLAN

     The Compensation Committee shall delegate to the Plan Administrative 
Committee the power and authority to administer the Plan. The Plan 
Administrative Committee shall have full authority in its discretion to 
determine the participation level of each Participant. Except as otherwise 
provided herein and subject to the provisions of the Plan, the Plan 
Administrative Committee shall have full and conclusive authority to 
interpret the Plan; to determine the terms and provisions of any Repayment 
Obligation; and to make all other determinations necessary or advisable for 
the proper day to day administration of the Plan. The Plan Administrative 
Committee shall not have the power or authority to determine the persons 
eligible to participate in the Plan, materially increase any benefits offered 
under the Plan; to materially increase the Company's financial commitments; 
or to prescribe, amend and rescind rules and regulations relating to the 
Plan. The Plan Administrative Committee's determinations under the Plan need 
not be uniform and may be made by it selectively among persons who are 
eligible to participate in the Plan. The Plan Administrative Committee's 
decisions shall be final and binding on all Participants.

9.   MISCELLANEOUS

     (a)   The Plan shall become effective on September 1, 1997 or such other 
date as designated by the Board.

     (b)   No benefit under the Plan shall in any manner be liable for or 
subject to the debts, contracts, liabilities, engagements, or torts of the 
Participant entitled to benefits under the Plan, and any attempt to 
anticipate, sell, transfer, assign, pledge, encumber, or charge the same 
shall be void.

     (c)   The titles and headings of the Sections of the Plan are placed 
herein for the convenience of reference only, and in the case of any 
conflicts, the text of the Plan, rather than the titles or headings, shall 
control.

     (d)   The masculine pronoun, wherever used herein, shall include the 
feminine pronoun, and the singular shall include the plural, except where the 
context requires otherwise.

     (e)   The provisions of the Plan shall be construed according to the 
laws of the State of Florida, and the venue and jurisdiction of any suit with 
respect to the Plan shall lie solely in the state or federal courts located 
in Broward County, Florida.

                            PARTICIPATION LEVELS


     The number of shares of Stock which may be initially acquired by a 
Participant under the Plan shall be determined as of September 1, 1997, based 
on Participant's base salary and the fair market value of the stock as of 
such date, or at such later dates as the Compensation shall determine for 
future Participants who are selected to participate in the Plan after 
September 1, 1997. The number of shares of Stock which may be acquired by a 
Participant hereunder shall be adjusted as of each subsequent September 1 
based on the Participant's base salary, position, and the fair market of the 
Stock on each such date. The number of shares of Stock which may be acquired 
by a Participant under the Plan shall not exceed the Participant's base 
salary multiplied by the applicable multiplier, based upon Participant's 
position with the Company, set forth below, divided by the fair market value 
of the Stock:
