       Jubilee Field Unit Operator Provides Revised Production Forecast

Business Wire

DALLAS -- January 15, 2014

Kosmos Energy Ltd. (“Kosmos”) (NYSE: KOS) announced today that Tullow Oil plc
(LSE: TLW), the operator of the Jubilee field, has provided a revised
production forecast of 100,000 barrels of oil per day (Bopd) for the full year
2014. This rate allows for a potential two-week shutdown for regular
maintenance at the Jubilee floating production, storage, and offloading vessel

Based on the operator’s revised production guidance, Kosmos’ net interest in
the field’s 2014 production is approximately 24,100 Bopd, similar to 2013 net
production levels. As a result, Kosmos currently expects to sell eight crude
oil cargoes during 2014.

The revised forecast is unrelated to reservoir performance and well
productivity, which remain strong. The new forecast primarily stems from the
recently completed third gas injection well which started up in the fourth
quarter of 2013 and provided minimal relief. Additionally, delays in restoring
full water injection during 2013 further compounded the gas handling
challenges. Restoration of full water injection was achieved late in the
fourth quarter.

Short, medium and longer-term options to ameliorate the situation in the best
interest of all stakeholders are being discussed with Ghanaian authorities.
The Ghana National Gas Company’s Western Corridor Gas Infrastructure system is
currently expected to be ready to receive gas from the Jubilee field in late
2014. Achievement of the revised production forecast is contingent on the
timely resolution of these matters.
