Proposed Acquisition of UK and French assets from EnCore Oil plc

September 23, 2009

The Directors of Egdon Resources plc are pleased to announce that the Company is in advanced negotiations to acquire a portfolio of UK and French assets from EnCore Oil plc (“EnCore”).The assets to be acquired would comprise of EnCore’s entire interest in 10 onshore UK licences, 2 onshore French licences and an interest in the Ceres gas field on the UKCS.The consideration, which will be satisfied in Egdon Ordinary Shares, will be finalised as part of the contract negotiations and the transaction will be structured so that on completion EnCore’s ownership will not exceed 29.9% of the enlarged share capital.The transaction is subject to final agreement of terms, completion of detailed due diligence, and shareholder and regulatory approval.Egdon and EnCore expect to make further announcements in due course.Commenting on the negotiations, Mark Abbott, Managing Director of Egdon said;

“This proposed transaction would mark a step change for Egdon’s portfolio. The assets significantly strengthen our opportunity base in the UK and France, with the Ceres field providing further near-term production and cash-flow coupled with the increased interest in the Kirkleatham gas field development to a more material 40% level. We also welcome the confidence placed in Egdon’s ability to add value to these assets by the management of EnCore through its shareholding in the Company.”

Commenting on the negotiations, Alan Booth, EnCore’s Chief Executive Officer said:

“We believe that by combining these assets with those of Egdon, we would expose our shareholders to more easily recognisable value in a more material portfolio of similar onshore assets. Egdon, as a committed and well established onshore player would be better placed to develop and add significant value to the enlarged asset base.“We are firmly of the view that it is possible to build a meaningful onshore E&P business, however this will need both scale and management focus. It is our view that this transaction would enable Egdon to accelerate its transition into a significant onshore E&P player.”
