April 22, 1998 Dear Shareholder: Recently, you received our Proxy Statement and Proxy Card for the Annual Meeting of Stockholders to be held at 10:00 a.m. (EDT) on Thursday, May 7, 1998 at the executive offices of the Company, 2050 Spectrum Boulevard, Fort Lauderdale, Florida 33309. The Proxy Statement (Item 3) seeks your approval to increase the authorized number of shares of the Company's Common Stock, par value $0.01 per share, from 50,000,000 to 100,000,000. We pointed out in the Proxy Statement that the additional authorized shares would be available for general corporate purposes and that the Company then had no specific plans to use the additional authorized shares. I am pleased to report that the Company has now decided to use a portion of the additional authorized shares for issuance in a public offering of Common Stock and Convertible Notes. For this reason, we are enclosing a Supplement to our Proxy Statement to provide you with full information about our plans. The Board of Directors recommends that you vote your shares "FOR" the proposal in Item 3 on your Proxy Card. We again invite you to attend our Annual Meeting. Thank you for your support and cooperation. Sincerely, Raymond Marcy CHAIRMAN, PRESIDENT AND CHIEF EXECUTIVE OFFICER INTERIM SERVICES INC. SUPPLEMENT TO PROXY STATEMENT DATED APRIL 22, 1998 APPROVAL OF PROPOSED AMENDMENT TO RESTATED CERTIFICATE OF INCORPORATION TO INCREASE AUTHORIZED SHARES OF COMMON STOCK (Item 3 on Proxy Card) The following supplements the discussion in the Proxy Statement concerning Item 3 on the Proxy Card. Interim intends to file registration statements with the Securities and Exchange Commission providing for a public offering (the "offerings") of (i) approximately 8,050,000 shares of its Common Stock, including the underwriters' over-allotment option, and (ii) $150,000,000 aggregate principal amount of its Convertible Subordinated Notes due 2005 (the "Notes"). The number of shares of Common Stock to be issued and the number of shares available for issuance upon conversion of the Notes will be subsequently determined based upon the trading price of the Common Stock and market conditions at the time of the offerings and such other factors as the Board of Directors of the Company deems relevant. The Company intends to use the additional shares of Common Stock for which authorization is sought in Item 3 of the Proxy Card in connection with the offerings, if consummated, and may use the additional authorized shares of Common Stock in connection with certain other opportunities which involve the issuance of additional shares of Common Stock, including, without limitation, as consideration for acquisitions consistent with its growth strategy and for such other purposes as the Board of Directors deems to be appropriate and in the best interests of Interim and its stockholders. THE BOARD OF DIRECTORS RECOMMENDS APPROVAL OF THE AMENDMENT OF THE COMPANY'S RESTATED CERTIFICATE OF INCORPORATION AND PROXIES SOLICITED BY THE BOARD WILL BE SO VOTED IN THE ABSENCE OF INSTRUCTIONS TO THE CONTRARY.
