Magellan Finalizes Rationalization of AU Amadeus Assets

Following the farm out to Vaalco of the deep formations in the Poplar fields in Montana, USA on September 6, 2011, Magellan has entered into an agreement to complete the rationalization of its asset portfolio in the Amadeus basin, Australia. Subject to customary approvals, the Company will acquire the remaining interest in the Palm Valley and Dingo fields, will sell its interest in the Mereenie field, and the Company has also entered into a long term gas sale agreement for its Palm Valley field.

Magellan Petroleum (N.T.) Pty Ltd, a wholly owned subsidiary of the Company, entered into a Sale Agreement, dated September 14, 2011 with Santos QNT Pty Ltd and Santos Limited ("Santos Entities) (such transaction referred to herein as the "Asset Swap").

The Asset Swap provides for the transfer of the Santos Entities' interest in the Palm Valley field and in the Dingo field of 48% and 66%, respectively, to Magellan NT and the transfer of Magellan NT's 35% interest in the Mereenie field to the Santos Entities. The Asset Swap will be effective as of July 1, 2011, subject to customary approvals. Upon completion of the Asset Swap, Magellan NT will receive a cash consideration of A$25 million. In addition, Magellan NT will be entitled to Bonus amounts with a cumulated possible value of A$17.5 million, based upon production volume thresholds at the Mereenie field over the next 20 years.

Furthermore, on September 14, 2011, Magellan NT and the Santos Entities entered into a long term Gas Supply and Purchase Agreement (the "GSPA") for the sale by Magellan NT to the Santos Entities of a total contract gas quantity of 25.65 PJ, which represents approximately all the remaining reserves of the Palm Valley field over a 17 year term. The contract is subject to completion of the Asset Swap and shall commence on the later of the first delivery of gas by Mereenie to a new gas customer and January 16, 2012, which is when the existing gas sales agreement for the Palm Valley Gas field expires. The price for gas supplied by Magellan NT shall be the weighted average of the prices obtained for all gas sold by the Santos Entities from the Mereenie field during the relevant contract year.

William Hastings, President and CEO commented, "The Asset Swap and the Vaalco transaction represent a significant milestone for Magellan. With significant cash reserves, minimal debt, and wholly owned and controlled assets both in Montana, USA and Australia, the Company is now well positioned to focus on developing its existing assets. The new gas contract for Palm Valley will enable the Company to properly value its reserves and with full control over the Dingo field, Magellan intends to renew its exploration program."
