SPOTLIGHT WESTERN SAHARA Western Sahara is a UN-designated Non-Self-Governing Territory one of 17 such territories in the world. We are extremely attentive to the sensitivity of the area and to the requirements of international law. We have been guided by the 2002 UN Legal Opinion on resource exploration and development in non- self-governing territories including its explicit application to exploration for hydrocarbons offshore Western Sahara. Kosmos current activities are focused on exploration and do not involve the production of resources. Our activities have yet to prove conclusively whether sufficient hydrocarbon resources are present to justify commercial development. Kosmos Energy and the Kingdom of Morocco have signed a Joint Declaration of Principles which made it clear that development of any commercially- viable hydrocarbon resources would only proceed in accordance with the 2002 UN Legal Opinion. Kosmos operates the Cap Boujdour license with a 55 percent equity interest along with ONHYM 25 percent and Capricorn Exploration and Development Company Limited a wholly-owned subsidiary of Cairn Energy PLC 20 percent. MANAGING OUR FOOTPRINT In late 2014 Kosmos began drilling its first exploration well offshore Western Sahara known as CB-1 to test the Al Khayr prospect a large structure containing several stacked Cretaceous-age reservoirs. On March 2 2015 Kosmos announced that the CB-1 exploration well had encountered hydrocarbons. The well penetrated approximately 14 meters of net gas and condensate pay in clastic reservoirs over a gross hydrocarbon bearing interval of approximately 500 meters. The discovery was non-commercial and the well was plugged and abandoned. The CB-1 well was designed to open the frontier Laayoune Basin. While not a commercial find this first well in the basin de-risked further exploration by demonstrating a working petroleum system including the presence of a hydrocarbon charge as well as effective trap and seal. The well results confirmed the substantial exploration potential of the Cap WESTERN SAHARA Kosmos has held rights to explore the Cap Boujdour block an area of approximately 22000 square kilometers located 70 kilometers offshore Western Sahara since 2006 under a petroleum agreement with the Kingdom of Morocco which includes our partner the Office National des Hydrocarbures et des Mines ONHYM. 26
