<p style="margin:0in 0in .0001pt;text-indent:.5in;"><font size="2" face="Times New Roman" style="font-size:10.0pt;">On </font><font size="2" style="font-size:10.0pt;">October&nbsp;10, 2013, a subsidiary of Kosmos Energy Ltd. (the &#147;<b>Company</b>&#148;), executed a petroleum agreement with the Office National des Hydrocarbures et des Mines (&#147;<b>ONHYM</b>&#148;), the national oil company of the Kingdom of Morocco, covering the Tarhazoute Offshore block, to which the Company previously held certain exploration rights under a 2011 reconnaissance contract. Under the terms of the petroleum agreement, the Company is the operator of the Tarhazoute Offshore block and has 75% participating interest. ONHYM holds a 25% carried interest in the block through the exploration period. The initial exploration period will last for two years and six months and will commence from the date specified in the exploration permits, which have yet to be finalized with the Government of Morocco and ONHYM. The exploration period may be extended for additional exploration extension periods of two years and six months and three years respectively. In the event of commercial success, the Company has the right to develop and produce oil or gas for a period of 25&nbsp;years from the grant of an exploitation concession from the Government of Morocco, which may be extended for an additional period of 10&nbsp;years under certain circumstances. The petroleum agreement is subject to customary government approvals.</font></p>

<p style="margin:0in 0in .0001pt;text-indent:.5in;"><font size="2" face="Times New Roman" style="font-size:10.0pt;">On </font><font size="2" style="font-size:10.0pt;">October&nbsp;14, 2013, a subsidiary of the Company executed three farm-out agreements with a wholly-owned subsidiary of BP plc (&#147;<b>BP</b>&#148;), relating to three blocks in the Agadir Basin, offshore Morocco.&#160; Under the terms of the respective farm-out agreements, BP will acquire non-operating interests of 45.0% in the Essaouira Offshore block, 26.325% in the Foum Assaka Offshore block and 45.0% in the Tarhazoute Offshore block. ONHYM will continue to hold its 25.0% carried interest in each of the three blocks through the exploration periods. BP will fund the Company&#146;s share of the cost of one exploration well in each of the three blocks, subject to a maximum spend of $120 million per well, and pay its proportionate share of any well costs above $120 million per well. In the event a second exploration well is drilled in any block, BP shall pay 150% of its share of costs up to a cap of $120 million per well and pay its proportionate share of any well costs above $120 million per well. BP shall also pay an aggregate of approximately $36 million for its share of past costs incurred by the Company attributable to the three blocks. Completion of the transactions pursuant to the farm-out agreements is subject to customary closing conditions, including Moroccan government approvals.</font></p>

Item 8.01.  Other Events.
On
October 10, 2013, a subsidiary of Kosmos Energy Ltd. (the "
Company
"), executed a petroleum agreement with the Office National des Hydrocarbures et des Mines ("
ONHYM
"), the national oil company of the Kingdom of Morocco, covering the Tarhazoute Offshore block, to which the Company previously held certain exploration rights under a 2011 reconnaissance contract. Under the terms of the petroleum agreement, the Company is the operator of the Tarhazoute Offshore block and has 75% participating interest. ONHYM holds a 25% carried interest in the block through the exploration period. The initial exploration period will last for two years and six months and will commence from the date specified in the exploration permits, which have yet to be finalized with the Government of Morocco and ONHYM. The exploration period may be extended for additional exploration extension periods of two years and six months and three years respectively. In the event of commercial success, the Company has the right to develop and produce oil or gas for a period of 25 years from the grant of an exploitation concession from the Government of Morocco, which may be extended for an additional period of 10 years under certain circumstances. The petroleum agreement is subject to customary government approvals.
On
October 14, 2013, a subsidiary of the Company executed three farm-out agreements with a wholly-owned subsidiary of BP plc ("
BP
"), relating to three blocks in the Agadir Basin, offshore Morocco.  Under the terms of the respective farm-out agreements, BP will acquire non-operating interests of 45.0% in the Essaouira Offshore block, 26.325% in the Foum Assaka Offshore block and 45.0% in the Tarhazoute Offshore block. ONHYM will continue to hold its 25.0% carried interest in each of the three blocks through the exploration periods. BP will fund the Company's share of the cost of one exploration well in each of the three blocks, subject to a maximum spend of $120 million per well, and pay its proportionate share of any well costs above $120 million per well. In the event a second exploration well is drilled in any block, BP shall pay 150% of its share of costs up to a cap of $120 million per well and pay its proportionate share of any well costs above $120 million per well. BP shall also pay an aggregate of approximately $36 million for its share of past costs incurred by the Company attributable to the three blocks. Completion of the transactions pursuant to the farm-out agreements is subject to customary closing conditions, including Moroccan government approvals.
On October 15, 2013, the Company issued a news release announcing the execution of the petroleum agreement for the Tarhazoute Offshore block and the three farm-out agreements with BP. A copy of the news release issued by the Company is attached hereto as Exhibit 99.1 and is incorporated herein by reference.
