Edge Petroleum Corporation Selects Prevailing Bidder in Bankruptcy Auction for the Sale of Substantially All of Its Assets and Obtains Bankruptcy Court Approval of Its Plan of Reorganization and the Related Sale Transaction

HOUSTON, Dec. 15, 2009 (GLOBE NEWSWIRE) -- Edge Petroleum Corporation (Pink Sheets: EPEX)(FREE stock trend analysis) (Pink Sheets: EPEXP)(FREE stock trend analysis) ("we", "our", "Edge" or the "Company") announced today that, on December 7, 2009, it and each of its Subsidiaries (defined below) concluded a bankruptcy auction pursuant to which Mariner Energy, Inc. ("Mariner") was selected as the prevailing bidder to purchase substantially all of the Company's assets (the "Assets"). The Assets include all of the Company's ownership interest in its direct and indirect subsidiaries, including Edge Petroleum Exploration Company, Miller Exploration Company, Edge Petroleum Operating Company, Inc., Edge Petroleum Production Company and Miller Oil Corporation (collectively, the "Subsidiaries" and together with Edge, the "Debtors").

As previously reported, in connection with the filing of the Debtors' voluntary petitions for reorganization (the "Chapter 11 Cases") under Chapter 11 of the United States Bankruptcy Code in the United States Bankruptcy Court for the Southern District of Texas, Corpus Christi Division (the "Bankruptcy Court"), the Company established an auction process to effect the sale of the Assets. As a result of the auction held on December 7, 2009 pursuant to which Mariner was selected as the winning bidder, on December 9, 2009 the Company and its Subsidiaries signed a Purchase and Sale Agreement with Mariner relating to the purchase and sale of the Assets (the "Mariner Purchase Agreement" and the transactions contemplated thereby, the "Sale Transaction"). Except as noted below, the Mariner Purchase Agreement contains substantially the same terms as the previously reported purchase agreement that the Company and its Subsidiaries signed with their stalking horse bidder, PGP Gas Supply Pool No. 3 ("PGP") on September 30, 2009 (the "PGP Purchase Agreement"). Consummation of the transactions contemplated by the Mariner Purchase Agreement is subject to the approval of the Bankruptcy Court and certain other closing conditions as set forth in the Mariner Purchase Agreement and on December 14, 2009 the Bankruptcy Court entered a confirmation and sale order confirming the Debtor's plan of reorganization and approving the Sale Transaction. The Sale Transaction is expected to close on December 31, 2009 and a pre-closing is expected to be held on December 22, 2009 at which time all documents required to be delivered at the closing will be delivered into escrow and the remaining purchase price (other than the previously escrowed deposit) will be deposited into escrow pending its release (and the release of the deposit) on the closing date.

Mariner's bid was the highest bid of the two qualified bidders, Mariner and PGP. Mariner's winning bid was $260 million, less a fixed gas price downward adjustment of approximately $23.9 million. PGP's highest bid was $243 million, with a maximum downward floating gas price adjustment of approximately $23.9 million. The base purchase price in the PGP Purchase Agreement was $191 million, with the same floating gas price downward adjustment cap. Pursuant to the Mariner Purchase Agreement, the effective date for the sale of the Assets is June 30, 2009. In addition to the fixed downward gas price adjustment, Mariner's purchase price is subject to a number of other adjustments relating to, among others, (i) costs and expenses incurred by the Debtors in connection with the maintenance of the Debtors' properties before and after the effective date, (ii) gas imbalance volumes, (iii) taxes, (iv) proceeds of production before and after the effective date, (v) unsold inventory as of the effective date, and (vi) prepaid items. The Mariner Purchase Agreement does not include a break-up fee or any related expense reimbursement in the event the Sale Transaction is not consummated. The proceeds from the sale of the Assets will be used to substantially reduce the Company's indebtedness under the Company's Fourth Amended and Restated Credit Agreement (as amended, the "Credit Agreement") among the Company, Union Bank, N.A. (f/k/a Union Bank of California, N.A), as administrative agent and as issuing lender, and the other lenders party thereto. The Company currently has approximately $226.5 million of outstanding principal under its Credit Agreement which the Company currently believes will be in excess of the proceeds expected to be available for distribution as a result of the Sale Transaction and after taking into account all adjustments and other distributions contemplated with respect thereto. As a result, it is unlikely that any material amount, if any, of proceeds will be available for distribution to the Company's unsecured creditors or, in the unlikely event that such unsecured creditors received payment in full, that the holders of the Company's 5.75% series A cumulative convertible perpetual preferred stock will receive any recovery. The holders of the Company's common stock will also not be entitled to any recovery upon consummation of the Sale Transaction even under the most optimistic of circumstances which the Company believes would still not be likely to result in proceeds in excess of the amount owing to the Company's secured creditors.

The auction and sale process conducted by the Company's management was the culmination of strategic efforts to maximize and realize the value of the Assets.

Pending the consummation of the Sale Transaction, the Company expects to continue to manage its properties and operate its businesses in the ordinary course. The Company intends to use the proceeds of the Sale Transaction to pay down its indebtedness. The Company notes that the total amount of principal, fees and interest outstanding under Credit Agreement was approximately $227.6 million as of the filing date of the Chapter 11 Cases, which, as noted above, is an amount which the Company believes is in excess of the amount which will be available to be distributed as a result of the Sale Transaction. Stockholders of a company in chapter 11 generally receive value only if all claims of the company's secured and unsecured creditors are fully satisfied, which is not expected to occur as a result of the Sale Transaction. Accordingly, the Company's management would like to again inform investors that it does not expect that the Company's common stockholders or its 5.75% series A cumulative convertible perpetual preferred stockholders will receive any recovery and it is currently contemplated that the bankruptcy proceedings will result in the cancellation of these equity interests with no payment to the holders of those equity interests.

Pursuant to the terms of the PGP Purchase Agreement, PGP is entitled to a break up fee in the amount of $6.0 million (the "Break-Up Fee") and an expense reimbursement for any reasonable documented out-of-pocket fees and expenses owed or paid by PGP (collectively, not to exceed $500,000) to third parties actually incurred in the evaluation of PGP's bid, the negotiation and execution of the PGP Purchase Agreement and related documents, and efforts by PGP related to consummation of the transactions contemplated thereby (the "Expense Reimbursement"). The Company expects to pay the Break-Up Fee and the Expense Reimbursement on or about the time the Sale Transaction contemplated by the Mariner Purchase Agreement closes. PGP has agreed to serve as the Company's back-up bidder at its last bid set forth above. PGP would receive credit of $6.5 million for the Break-Up Fee and the Expense Reimbursement and be subject to generally the same adjustments as set forth in the Mariner Purchase Agreement, except for Mariner's fixed downward gas price adjustment. In the event that the Company failed to consummate the Sale Transaction and a transaction with PGP as the back-up bidder were to be consummated, the Company expects that the proceeds available for distribution as a result of a transaction with PGP would be less than the proceeds available for distribution with respect to the Sale Transaction (in each case after taking into account all adjustments and other distributions contemplated with respect thereto) and would therefore also be less than is owing to the Company's secured creditors.
