Edge Petroleum Corporation Receives Delisting Notice From The Nasdaq Stock Market

HOUSTON, Oct. 8, 2009 (GLOBE NEWSWIRE) -- Edge Petroleum Corporation
(Nasdaq:EPEX) (Nasdaq:EPEXP) ("Edge" or the "Company") announced today that on
October 2, 2009, it received notice (the "Notice") from The Nasdaq Stock Market
(the "Exchange") that the Company's common stock and 5.75% series A cumulative
convertible perpetual preferred stock will be delisted from the Exchange at the
opening of business on October 13, 2009 pursuant to the Exchange's Listing Rules
5100, 5110(b) and IM-5100-1, and a Form 25-NSE will be filed with the Securities
and Exchange Commission, which will remove the Company's securities from listing
and registration on the Exchange. According to the Notice, the determination to
delist the Company's securities was based on (i) the announcement by the Company
on October 2, 2009 that it and each of its subsidiaries have filed voluntary
petitions for reorganization under Chapter 11 of the U.S. Bankruptcy Code and
the associated public interest concerns raised by such bankruptcy petitions;
(ii) concerns regarding the residual equity interest of the existing listed
securities holders; and (iii) concerns about the Company's ability to sustain
compliance with all requirements for continued listing on the Exchange.

The Company may appeal the Exchange's determination to a Hearings Panel,
pursuant to the procedures set forth in the Exchange's Listing Rule 5800 Series.
However, the Company does not intend to take any further action to appeal the
Exchange's decision, and therefore it is expected that the Company's securities
will be delisted and trading suspended at the opening of business on October 13,
2009.

If the Company does not appeal the Exchange's decision, the Company's securities
will not be immediately eligible to trade on the OTC Bulletin Board or in the
"Pink Sheets." The Company's securities may become eligible if a market maker
makes application to register in and quote the security in accordance with SEC
Rule 15c2-11, and such application is cleared.
