("B&S" or "the Company")

Assignment Agreement

Borders & Southern Petroleum plc is pleased to announce that it has assigned two of its option wells under its contract for the drilling unit, Leiv Eiriksson, to Falkland Oil and Gas Ltd (FOGL). The two wells will follow on from B&S's Darwin and Stebbing wells, which are anticipated to commence drilling in December of this year.

Under the terms of the Assignment Agreement the companies will share mobilisation and demobilisation costs for the rig along with ancillary equipment and services.

Chief Executive, Howard Obee, commented:

"We are delighted to have signed this Agreement with FOGL. It will result in significant cost savings for Borders & Southern. Not only is it a great deal for both companies, it's also good news for the Falkland Islanders, as they will now see at least four wells drilled in the Southern basin".
