This strategy is designed to mitigate risk and ensure that upon successful exploration, projects can benefit from the development and production expertise provided by these partners. Kosmos Partners with BP in Mauritania and Senegal After successfully opening the Mauritania-Senegal basin, we secured a super-major partner that is fully aligned with our vision for advancing the Tortue gas project at pace while simultaneously executing a multi-well exploration program to test the basin’s liquids potential. In December 2016, we announced a partnership with BP in Mauritania and Senegal following a competitive process for our interests in our blocks offshore Mauritania and Senegal. In Mauritania, BP acquired a 62% participating interest in our four Mauritania licenses (C6, C8, C12 and C13). In Senegal, BP acquired a 49.99% interest in Kosmos BP Senegal Limited, our controlled affiliate company which holds a 65% participating interest in the Cayar Offshore Profond and the Saint Louis Offshore Profond blocks offshore Senegal. This participating interest gives effect to the completion of our exercise in December 2016 of an option to increase our equity in each contract area from 60% to 65% in exchange for carrying Timis Corporation’s paying interest share of a third well in either contract area. In consideration for these transactions, Kosmos will receive $162 million in cash up front, $221 million exploration and appraisal carry, up to $533 million in a potential development carry and variable consideration up to $2 per barrel for up to 1 billion barrels of liquids, structured as a production royalty, subject to future liquids discovery and prevailing oil prices. In addition to demonstrating the value of our strategy and validating the quality of the Mauritania- Senegal basin, the transaction strengthened our balance sheet by materially reducing our future capital expenditure requirements, effectively funding our Mauritania- Senegal work program for the next several years. In light of our shared view of the basin’s potential, Kosmos and BP also entered into an exclusive exploration partnership covering potential new ventures opportunities in Mauritania, Senegal and The Gambia. Hess Corporation Brings Regional Technical Knowledge to Suriname Partnership Given recent industry success in the basin, Suriname is a top ranked opportunity in our exploration portfolio. Our farm-out agreement with Hess Corporation, which is a partner in recent industry discoveries offshore neighboring Guyana, brings important regional technical expertise to the partnership. The farm-out, which covers Block 42, was executed in an industry environment of capital constraints, and validated the quality of our acreage position and the ongoing work to mature a number of significant prospects toward drilling. The terms of the agreement are consistent with our business strategy of retaining operatorship through exploration and collaborating with industry- leading partners who bring both technical and regional expertise, as well as strong financial capabilities. Partnership with Galp in Sao Tome and Principe In 2015 and 2016, Kosmos acquired acreage in four blocks offshore Sao Tome and Principe, marking a strategic re-entry into the Gulf of Guinea. These blocks cover an area of approximately 25,000 square kilometers and are adjacent to a proven petroleum system in Equatorial Guinea and Gabon. Kosmos reached an agreement in 2016 with Galp to farm out a 20 percent non-operated stake in blocks 5, 11, and 12 offshore Sao Tome and Principe, bringing the company in across all our acreage and enabling us to jointly explore the basin with full technical alignment. As a Portuguese company, Galp brings to the partnership strong above-ground capabilities which should prove valuable as we progress toward drilling.
