Business Wire

DALLAS -- October 15, 2013

Kosmos Energy (NYSE: KOS) today announced that it has entered into three
farm-out agreements with BP plc (LSE: BP) (NYSE: BP), covering three blocks in
the Agadir Basin, offshore Morocco. Under the terms of the agreements, BP will
acquire a non-operating interest in each of the Essaouira Offshore, Foum
Assaka Offshore and Tarhazoute Offshore blocks. BP will fund Kosmos’ share of
the cost of one exploration well in each of the three blocks, subject to a
maximum cost per well. In the event a second exploration well is drilled in
any block, BP shall pay a disproportionate share of the well cost subject to a
maximum cost per well. BP shall also pay its proportionate share of past
costs. Completion of the transactions is subject to customary closing
conditions, including Moroccan Government approvals.

Kosmos also announces that it has recently signed a petroleum agreement with
the Office National des Hydrocarbures et des Mines (ONHYM) covering the
Tarhazoute Offshore block, previously held under a reconnaissance contract
since 2011. The Tarhazoute block is contiguous with the Essaouira and Foum
Assaka blocks and will allow integrated exploration over a significant portion
of the Agadir Basin, one of the last remaining underexplored salt basins along
the Atlantic Margin.

Brian F. Maxted, Chief Executive Officer, Kosmos Energy, commented: “The
Agadir Basin farm-out along with the petroleum agreement for Tarhazoute mark
significant and important forward steps for Kosmos in Morocco as we prepare to
commence drilling in the first half of 2014. We are delighted that BP will be
joining this venture as they add significant value to our operations,
particularly given their proven success in salt basin exploration and
