Prospect Medical Holdings Enters into Credit Agreement Amendments with Lenders and Provides Financial Filings Update

Prospect Medical Holdings, Inc. (AMEX: PZZ) ("Prospect” or "the Company”), which manages the medical care of approximately 240,000 HMO enrollees and operates four community hospitals in southern California, today announced that it has obtained covenant waivers and other credit agreement amendments ("the amendments”) from all participating lenders in its $155 million senior secured credit facility. Prospect entered into this facility in connection with the August 2007 acquisition of Alta Hospitals System, LLC ("Alta”). A Form 8-K to be filed by Prospect will provide additional details about the amendments. Prospect has substantially completed the work necessary to file its Form 10-K for the fiscal year ended September 30, 2007 and Form 10-Q for the quarter ended December 31, 2007. However, as previously disclosed, these filings have been delayed pending the completion of discussions between the Company and its lenders with respect to the amendments. With the signing of these amendments, Prospect can now complete the process of filing the above referenced Form 10-K and 10-Q reports. Prospect continues to expect to file its fiscal 2007 Form 10-K by the end of May 2008, and its first and second quarter 2008 Form 10-Q filings shortly thereafter, with full completion of all filings on or before June 16, 2008. As detailed in previous announcements, following the filings, as outlined above, and the meeting of certain other terms and conditions, Prospect believes it will be compliant with the continued listing requirements of the AMEX and will qualify for its common stock to resume trading.
