# # #

Houston, TX - With $500 million in financial backing by Carlyle/Riverstone and Goldman Sachs Capital Partners, a team of petroleum industry leaders today announced the launch of Cobalt International Energy, L.P., which will engage in oil and gas exploration and production in the Deepwater Gulf of Mexico and other high-potential global basins. The company will be headquartered in Houston, Texas.

Leading the effort are five outstanding and highly experienced industry executives: Joseph H. Bryant, Chairman and Chief Executive Officer (former President and Chief Operating Officer of Unocal Corporation); Samuel H. Gillespie, Vice Chairman (former General Counsel of Mobil Corporation and Unocal Corporation); James H. Painter, Executive Vice President of Exploration (former Senior Vice President of Exploration at Unocal Corporation and Ocean Energy); and James W. Farnsworth (Vice President for World-Wide Exploration and Technology at BP), who will join Cobalt as President and Chief Operating Officer effective February 1, 2006.  Also forming part of the leadership team is Laura E. Muñoz of Wachtell, Lipton, Rosen & Katz, who will join the team in early January as Executive Vice President and General Counsel.

“I believe that the outstanding team that we have formed, utilizing the best technology and backed by a group of respected investors, will yield impressive results,” said Mr. Bryant. “We will immediately hire critical technical team members who are experts in the basins where we will focus.  In addition, we have begun discussions with strategic industry players in the international exploration and production sector that may join the Cobalt investor team.  We expect that from the outset we will be competitive explorers in the Deepwater Gulf of Mexico and select international basins.”

"Oil and natural gas prices are high because of strong growth in demand. Exploration needs to keep pace with future growth,"  Mr. Bryant added.  “This makes Cobalt’s concentrated, technology-focused exploration all the more timely.  We believe that substantial oil and gas remain to be discovered, and we will quickly be in a position to deliver outstanding exploration and business results.”

David M. Leuschen, Co-founder of Riverstone Holdings and Managing Director of Carlyle/Riverstone Global Energy and Power Funds, said, “Joe has assembled a stellar executive team, which is among the most experienced, respected and skilled in the global exploration and production industry.  Along with the rest of the Cobalt team, we believe they will create a 'super-explorer' enterprise that will deliver great results."

Kenneth Pontarelli, Managing Director of Goldman Sachs Capital Partners, said, “We expect the Cobalt team to be formidable players from day one. They will engage in high-impact exploration on a global scale. The investor team of Goldman Sachs and Carlyle/Riverstone provides Cobalt the means to compete anywhere in the world.”
