Change in Registrant's Certifying Accountant On May 5, 1999, COMFORCE Corporation and COMFORCE Operating, Inc.

During the two most recent fiscal years and through May 5, 1999, there have been no disagreements with PWC on any matter of accounting principles or practices, financial statement disclosure or auditing scope or procedures, which disagreements, if not resolved to the satisfaction of PWC, would have caused them to make reference in their report on the financial statements for such years, or any "reportable events" within the meaning of Item 304(a)(1)(iv) of Regulation S-K. PWC's report on the financial statements for the past two years contained no adverse opinion or disclaimer of opinion and was not qualified or modified as to uncertainty, audit scope or accounting principles. The Registrants have provided PWC with a copy of this disclosure and have requested that PWC furnish them with a letter addressed to the SEC stating whether it agrees with the above statements. A copy of PWC's letter to the SEC, dated May 7, 1999, is filed as Exhibit 16 to this Form 8-K. Item 7. Financial Statements, Pro Forma Financial Information and Exhibits (c) Exhibits 16.
