Court Approves USEB's Settlement with Countryside

U.S. Energy Biogas Corp. ("USEB” or "the Subsidiary”), a U.S.-based renewable energy business, announced today that the United States Bankruptcy Court for the Southern District of New York has approved the settlement agreement reached between USEB and Countryside Power Income Fund (TSX: COU.UN) and announced on January 16, 2007. The approved settlement agreement enables USEB and its parent, U.S. Energy Systems, Inc. (Nasdaq: USEY), to establish new financing for USEB that should enable it to pay all of its creditors in full, exit bankruptcy quickly, and support the growth of the business for the benefit of USEY’s shareholders. "We are very pleased that USEB is continuing on an expedited path through its restructuring,” said Asher E. Fogel, Chairman of USEB and Chief Executive Officer of USEY. "The Court’s approval of our settlement agreement should facilitate full payment of existing creditors’ claims. Moreover, it means that USEB can move forward to establish new financing, its management can capitalize on USEB’s attractive growth opportunities, and USEY’s shareholders can benefit from the value of USEB.” The settlement provides for Countryside Canada Power Inc, a subsidiary of Countryside, to have an allowed secured claim of approximately US$99,000,000, of which US$3,000,000 has been paid by USEY. Under the settlement, the secured claim is the only allowed claim that Countryside will have in the Chapter 11 case. As a result of the settlement, Countryside has no claim concerning USEB’s April 8, 2004 Royalty Agreement with Countryside, nor any claim against USEY under its April 8, 2004 Development Agreement with Countryside. The settlement provides for USEB to make an installment cash payment of US$30,000,000 against the remaining US$96,000,000 of Countryside’s claim on or before March 31, 2007, with the remaining balance of the secured claim due on or before maturity at May 31, 2007. USEB stated that it intends to make the US$30,000,000 installment payment as soon as practicable in order to minimize its interest expenses. Other significant terms of the settlement agreement are described in USEB’s January 16, 2007 press release. Hunton & Williams LLP serves as legal advisor to USEB. Wilmer Cutler Pickering Hale and Dorr LLP serves as special counsel to USEY in connection with USEB's Chapter 11 cases.
