NOT FOR DISTRIBUTION TO U.S. NEWSWIRE SERVICES OR FOR DISSEMINATION IN THE UNITED STATES. ANY FAILURE TO COMPLY WITH THIS RESTRICTION MAY CONSTITUTE A VIOLATION OF U.S. SECURITIES LAWS.

Greenfields Petroleum Corporation (the "Company" or "Greenfields") (TSX VENTURE:GNF) announced today that it has been advised that Baghlan Group Limited ("Baghlan") has executed a Share Purchase Agreement for the acquisition of Rafi Oil FZE's ("Rafi") 33.33% interest in Bahar Energy Limited ("BEL") for a purchase price of US $150 million. Baghlan is one of the Company's fellow shareholders in BEL and previously held a 33.34% interest. Rafi, Baghlan and a subsidiary of Greenfields were the initial three owners of BEL. After the completion of the transfer of shares, Baghlan will hold a 66.67% interest in BEL while Greenfields' interest will remain unchanged as a result of the acquisition.

BEL is a Dubai-based company which operates and participates in an oil and gas exploration, rehabilitation and development profit sharing agreement ("Bahar ERDPSA") in Azerbaijan. The state-owned oil company SOCAR and its affiliate SOA also participate in the Bahar ERDPSA. The proposed sale will have no effect on Greenfields with respect to its existing 33.33% ownership position in BEL, and it will have no effect on BEL's contractual rights or obligations under the Bahar ERDPSA.

John W. Harkins, President and Chief Executive Officer, commented "we are very pleased with Baghlan's announced intent to purchase the Rafi interest in Bahar Energy Limited, because it further indicates the significant value and future potential that exists in our Bahar ERDPSA project. We welcome the new arrangement and we are looking forward to a closer working relationship with our partner as together we implement our drilling and recompletion program in the coming months in the Gum Deniz oil field and the Bahar gas field".
