- Listed Companies Are Afforded Up To 360 Days to Regain Compliance with Minimum Bid Price Rule Under Nasdaq Marketplace Rules -

TUSTIN, Calif., July 25 /PRNewswire-FirstCall/ -- Peregrine Pharmaceuticals, Inc. (Nasdaq: PPHM), a clinical stage biopharmaceutical company developing monoclonal antibodies for the treatment of cancer and hepatitis C virus (HCV) infection, today announced that it has been notified by The Nasdaq Stock Market that for the past 30 business days the company has not met the $1.00 minimum closing bid price requirement as set forth in Marketplace Rule 4310©(4). According to the Nasdaq notice, Peregrine will be automatically afforded an initial 180 calendar days, or until January 22, 2008, to regain compliance with this requirement. To regain compliance, the closing bid price of Peregrine's common stock must meet or exceed $1.00 per share for 10 consecutive business days. This notification has no effect on the Nasdaq listing or trading of the company's common stock.

According to Nasdaq market regulations, companies are eligible for an additional 180-day period to regain compliance provided that on the 180th day of the first compliance period, the company demonstrates that it meets the criteria for initial listing set forth in Rule 4310©, except for the minimum bid price requirement. Peregrine currently meets all other listing requirements set forth in Rule 4310©.

"We have made significant progress in our clinical programs in recent months, yet this progress has not yet been reflected in our share price," said Steven W. King, president and CEO of Peregrine. "We believe that in every other respect Peregrine's future prospects have never been brighter, and we intend to use the proceeds of our recent financing to pursue our three major clinical programs aggressively. These include plans for multiple Phase II studies with bavituximab for the treatment of various solid tumors, our ongoing Phase II Cotara® study for the treatment of brain cancer, and the ongoing hepatitis C virus program in patients co-infected with HIV. We believe that continued progress in these efficacy studies has the potential to create significant shareholder value going forward."

If Peregrine does not regain compliance during the initial or the potential additional compliance period, Nasdaq would provide written notice to the company that its common stock would be de-listed.
