Under the terms of the agreement, Cairn will acquire a 20% non-operated interest in the exploration permits comprising the Contract Area.

Cairn will pay a disproportionate share of future exploration costs including a 3D seismic survey, an initial exploration well in 2014 and, if successful, two appraisal wells, all subject to maximum expenditure caps.

Completion of the transaction is subject to customary closing conditions, including Moroccan Government approvals.

Kosmos Energy CEO Brian Maxted said, "Our farm-out with Cairn marks a significant step forward for Kosmos as we continue to advance our exploration plans while retaining a strategic position in the block and operatorship in one of the last undrilled petroleum systems along the Atlantic Margin."
