BLOCK CI-526 BLOCK CI-602 BLOCK CI-603 BLOCK CI-707 BLOCK CI-708 Gulf of Guinea CÔTE D’IVOIRE CÔTE D’IVOIRE In late 2017, Kosmos acquired five blocks offshore Côte d’Ivoire as part of a second cycle exploration initiative in the Gulf of Guinea. As an extension of the Tano Basin in Ghana, which the Kosmos exploration team opened with the Jubilee discovery in 2007, offshore Côte d’Ivoire provides an opportunity for Kosmos and our partner BP to execute a frontier/emerging basin exploration strategy and pursue new technical themes. Kosmos and BP each acquired an equal 45%-45% working interest in five contiguous blocks covering approximately 17,000 square kilometers, as shown in the map at left. PETROCI, the national oil company of Côte d’Ivoire, has a 10% carried working interest in the blocks as well. Kosmos is the exploration operator and BP will be the development operator in the event of a commercial discovery. A multi-client 3D seismic acquisition program is being conducted by Petroleum Geo-Services (PGS) in 2018, including over 12,000 square kilometers in Kosmos’ blocks during the first half of the year. The seismic survey uses sound waves to map rock formations on and below the ocean floor to establish the potential presence of hydrocarbons. If the seismic surveys show that formations potentially containing adequate oil and gas may exist, then Kosmos and BP will determine where to drill an exploration well. In 2018, Kosmos plans to open an office in Côte d’Ivoire and begin putting together a small team of employees based in the capital city of Abidjan. We are currently analyzing opportunities for early social investment programs as well. ENTERING PHASE 1 PHASE 2 PHASE 3 PHASE 4 PHASE 5 PHASE 6
