PORTLAND, Maine, May 18 /PRNewswire-FirstCall/ — Magellan Petroleum Corporation (Nasdaq: MPET) (ASX: MGN) announced that the Company has signed a term sheet (the “Term Sheet”) with Young Energy Prize S.A. (“YEP”), a Luxembourg corporation, embodying an agreement in principle for an additional equity investment in the Company of $15.6 million. Currently, YEP owns approximately 27% of the outstanding shares of the Company’s Common Stock, calculated as if the warrants to purchase shares of such stock held by YEP were fully exercised. The financing transaction set forth in the Term Sheet, upon completion, would result in YEP owning approximately 33% of the Company’s Common Stock, calculated as if such warrants were fully exercised. The Term Sheet is subject to the negotiation, execution and delivery of definitive documentation and the Company’s receipt of a favorable fairness opinion.

YEP, the Company’s strategic investor since July 2009, is a European firm targeting investments in the exploitation of underdeveloped oil and gas fields and in energy small-cap, equity issues. YEP has informed the Company that it may make its investment in part through the ECP Fund, SICAV-FIS (the “ECP Fund”), a specialized investment fund based in Luxembourg. Closing of YEP’s additional investment is related to the payment of Evans Shoal planning work and the second Evans Shoal disbursement to Santos Limited and will be set to be consistent with the Company’s future commitment dates for Evans Shoal development. The Company expects the closing to occur within 120 days and the Term Sheet contemplates an outside closing date of October 31, 2010.

Magellan’s President and Chief Executive Officer, William H. Hastings said, “This is the first step in the financing process for the purchase of a 40% interest in the Evans Shoal field, offshore Australia. We are working other, parallel initiatives which, when complete, will yield major new investment in the Company.  We expect to use the majority of equity funding for the purchase of the field interest and the planning, testing, analysis, and drilling of Evans Shoal subject to the Evans Shoal Joint Venture sanction and approval. A portion of the proceeds will go towards project development in addition to proceeds from other parallel initiatives.”

Walter McCann, Magellan’s Chairman of the Board, stated, “Progress continues with regard to our plans to build a strong Company with new, attractive assets. We remain positive that continued methodical, step-by-step efforts will yield strong value for our shareholders in the future.”

Nikolay V. Bogachev is Chairman and CEO of YEP. Of the financing transaction, he said “YEP continues to believe in Magellan’s business models and, based on recent key progress, wishes to invest further in Magellan.”

J. Thomas Wilson, First Vice President of YEP said, “This is the first step toward an ambitious plan building key assets in strategic, low-cost areas to supply energy for the inevitable future demand growth in Asia.”

Under the Term Sheet, YEP would acquire an additional 5,200,000 shares of the Company’s Common Stock (the “Shares”) at a price of $3.00 per share (the “Transaction”), pursuant to a securities purchase agreement to be negotiated.  The Company would also grant customary registration rights to YEP with respect to the Shares.  The Term Sheet also provides for certain percentage-maintenance rights for YEP, certain restrictions on transfers of the Shares and certain standstill obligations.
