  Kosmos Energy Finalizes Cap Boujdour Farm-out with Cairn Energy

Business Wire

DALLAS -- October 28, 2013

Kosmos Energy (NYSE:KOS) today announced that it has entered into a farm-out
agreement with Capricorn Exploration & Development Company Limited, a
wholly-owned subsidiary of Cairn Energy PLC (LSE:CNE), covering the Cap
Boujdour Contract Area. 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.

Brian F. Maxted, Chief Executive Officer of Kosmos Energy, commented, “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. This agreement is consistent with our strategy of
bringing industry leading partners such as Cairn who have significant
technical expertise, strong financial capabilities and a proven management
team to the Cap Boujdour project. This concludes the pre-drill farm out of our
Moroccan assets.”

Simon Thomson, Chief Executive of Cairn Energy commented, "This new acreage
offers significant potential in a region where Cairn is already well
established. We are delighted to be working with Kosmos who are a proven and
valuable operating partner with a track record of exploration success in this
play type along the West African margin. The farm-in builds on our existing
Atlantic Margin portfolio where we have a strategic presence across three
countries in Morocco, Senegal and Mauritania and has commenced a twelve month
multi-well high impact frontier exploration program that will potentially
offer shareholders material growth."

On closing of the transaction, the interests in the block will be as follows
with the Office National des Hydrocarbures et des Mines (ONHYM), having a
carried interest through the exploration period:

Kosmos                55.0% (Operator)
Cairn (Capricorn)         20.0%
ONHYM                     25.0%

Kosmos has held rights to conduct exploration activities in the Cap Boujdour
Contract Area since 2006 under a petroleum agreement with ONHYM. The Cap
Boujdour Contract Area comprises 29,740 square kilometers located
approximately 70 kilometers offshore Western Sahara.
