Carlyle-Riverstone to Fund Phoenix Exploration

With an initial financial commitment of $250 million from Carlyle/Riverstone Global Energy and Power Funds, a team of exploration and production executives announced the formation of a new company for oil and gas exploration and property acquisitions in the Gulf Coast and Gulf of Mexico regions. Phoenix Exploration Company, headquartered in Houston, Texas, will be led by a team of five energy industry veterans who most recently were associated with the highly successful performance of Gryphon Exploration Company. Funds for the investment will come from Carlyle/Riverstone Global Energy and Power III, LP, a $3.8 billion fund.

David M. Leuschen, Co-founder of Riverstone, said, "Bill Flores and his management team have extensive and distinguished careers in the oil and gas industry. Their track record is well established, as evidenced by their prior success at Gryphon, and they have a common vision of how to build value in today's competitive environment. We are excited to pursue opportunities in a geographic area where the Phoenix management has had considerable success."

William H. Flores, Chief Executive Officer of Phoenix, said, "Our goal is to build a dynamic and agile company focused on value creation. A proven team and business strategy with access to capital and a proven energy investor in Carlyle/Riverstone will enable us to efficiently execute our strategy of exploration and acquisitions. We look forward to working with the Carlyle/Riverstone team and appreciate their confidence and support. With this initial commitment, we are now actively building a proven, experienced exploration team and a robust exploration infrastructure to support their efforts. Also, with the core leadership of our operations and business development teams in place, we are assembling the remaining elements of a group of high performance individuals who know how to create value and operate efficiently with an emphasis on safety and integrity. The environment in which we operate today is challenging, but nonetheless, it is full of opportunities for teams that focus on these attributes. I am happy to be associated with such a team."

Daniel A. D'Aniello, Co-founder of The Carlyle Group, said, "Carlyle/Riverstone funds achieve premium returns through innovative and thoughtful investing. We have great confidence that Phoenix will sustain and bolster this track record."

The principals of Phoenix each most recently served in senior positions at Gryphon. Gryphon was formed in late 2000 and was acquired in August 2005 by Woodside Energy for approximately $310 million. Gryphon was capitalized by equity contributions from its management team and Warburg Pincus, as well as the contribution of certain assets from Cheniere Energy.
