News Release Details

REDWOOD CITY, Calif., Nov 22, 2010 (BUSINESS WIRE) -- A.P. Pharma, Inc. (NASDAQ:APPA), a specialty pharmaceutical company, today announced that, on November 17, 2010, it received a second letter from the Listing Qualifications Staff of The NASDAQ Stock Market (NASDAQ) indicating that it has not regained compliance with Listing Rule 5550(a)(2), which requires the closing bid price of the Company's common stock to be $1.00 or more.

This letter is a follow-up to the letter received from NASDAQ on May 18, 2010, which notified the company that it was out of compliance with Listing Rule 5550(a)(2) because the bid price of its common stock had closed at less than $1.00 per share over the previous 30 consecutive business days. At that time, NASDAQ provided the Company with 180 calendar days, or until November 15, 2010, to regain compliance with the rule.

The second letter from NASDAQ stated the Company's securities would be subject to delisting from The NASDAQ Stock Market, effective November 29, 2010, unless the Company requests a hearing before a NASDAQ Listing Qualifications Panel (Panel). A.P. Pharma intends to request a hearing before the Panel at which it will present its plan for regaining compliance with all applicable listing requirements. The hearing request will result in the Company's shares remaining listed on The NASDAQ Capital Market at least until such time as the Panel renders its decision following the hearing.

There can be no assurance that the Panel will grant the Company's request for continued listing on The NASDAQ Stock Market. In the event that the Panel determines to delist the Company's securities from NASDAQ, the Company's common stock may be eligible for trading on the OTC Bulletin Board, which is operated by FINRA or the OTCQB, which is operated by OTC Markets, Inc.
