ANNOUNCEMENT OF AN AMALGAMATION AGREEMENT AND FIRM WELL COMMITMENT

The Perth Licence co-venturers in Block 15/21a, DEO Petroleum UK Limited, Faroe Petroleum UK Limited, Maersk Oil UK Limited and Atlantic Petroleum UK Limited (together the "Perth Group") are pleased to announce that they have reached commercial agreement with the Block 15/21g co-venturers, EnCore Oil plc, Nautical Petroleum plc and Serica Energy (UK) Limited (together the "15/21g Group"), on the amalgamation of a sub area of 15/21a with Block 15/21g to create a single conjoined area (the "Amalgamated Area").

Under the terms of the agreement the parties, subject to the necessary DECC consent and the formulation of a detailed legal agreement, will have the following respective equities in the newly Amalgamated Area:

The parties have also confirmed a firm well commitment to DECC on the Spaniards prospect to assess whether it is a continuation of the updip Gamma discovery which flowed at 2,660 bopd from the Upper Jurassic Galley sands. The Spaniards well is expected to be drilled in the second half of 2012 and will satisfy the licence and fallow commitments. The Spaniards well is to be funded 100% by the 15/21g Group on a dry hole basis. It is agreed that the costs of any second well will be borne 42.8% by the Perth Group and 57.2% by the 15/21g Group again on a dry hole basis.

 David Marshall, DEO Chief Executive Officer Comments:

"We are pleased that the respective groups have been able to reach agreement on the amalgamation of the equity as well as commiting to the drilling of an appraisal well. This offers the opportunity for the Perth Group to enhance the unappraised Gamma discovery into a meaningful commercial accumulation. Gamma/Spaniards is in close proximity to our Perth field where we are continuing to progress our plans for field development. This demonstrates an important step for DEO in becoming a leading, multi-asset exploitation and production company in the Central North Sea".
