The Company announces that its subsidiary, SOCO Exploration and Production Congo ("SOCO EPC"), has entered into a farm-out agreement wherein it has agreed to farm-out 18.75% of its interest in the Marine XI block, offshore the Republic of Congo (Brazzaville), to each of a subsidiary of Lundin Petroleum AB and Raffia Oil SARL.

The block, located in the Lower Congo Basin, is in shallow water adjacent to the coast with water depths ranging up to 110 metres and covers approximately 1,400 square kilometres.

A contract has been awarded to PGS Overseas AS for the acquisition of a 1,200 square kilometre 3D seismic programme. The Ramform Explorer is expected to begin acquisition in early October.
The assignment of interests in the Agreement is subject to approval of the appropriate regulatory authorities of the Government of the Republic of Congo (Brazzaville).
