ANNUAL MEETING OF STOCKHOLDERS
To be held May 27, 2009

Dear Stockholders:

     This proxy statement supplement is furnished by our Board of Directors in connection with the solicitation of proxies for use at the 2009 Annual Meeting of Stockholders of ReSearch Pharmaceutical Services, Inc.

     After mailing our proxy statement on April 30, 2009, it came to our attention that the proxy card included with the proxy statement mailed to our stockholders inadvertently and incorrectly listed the date of the Annual Meeting as Tuesday, June 3, 2009. The correct date of the Annual Meeting isWednesday, May 27, 2009. The correct date of the Annual Meeting was included in the proxy card filed with the Securities and Exchange Commission.

     A corrected proxy card is enclosed. If you have already completed and returned the proxy card mailed earlier, please complete and return the enclosed proxy card in the return envelope provided. If you have not already completed and returned the proxy card mailed earlier, please discard the earlier proxy card and complete and return the enclosed proxy card in the return envelope provided.

     This proxy statement supplement will be mailed to our stockholders on or about May 13, 2009.

Sincerely,

STEVEN BELL
