Ceridian Receives Extension From Lenders.

MINNEAPOLIS -- Ceridian Corporation (NYSE:CEN) announced today that it has amended its $350 million domestic revolving credit facility and $150 million Comdata receivables securitization facility to allow additional time to deliver its Form 10-Q for the second quarter to its lenders through November 9, 2004, without the delayed delivery constituting a default under these agreements.

The Company also announced today that the Audit Committee of its Board of Directors is in the process of completing its internal review focusing on the capitalization and expensing of certain costs in the Company's Human Resource Solutions business. Although the Audit Committee's internal review is ongoing and no conclusions have been reached, the Company currently anticipates that a restatement of its prior financial statements and a revision to its current guidance will be necessary, and that accordingly, such financial statements and guidance should no longer be relied upon. The Company will announce the results of and file its Form 10-Q for the quarterly period ended June 30, 2004, and amend the appropriate prior filings with the Securities and Exchange Commission, as soon as practicable following the Audit Committee's completion of its internal review.
