TPG Capital to Purchase Majority Stake in Valerus Compression Services

Chet Erwin will continue in his capacity as Chief Executive Officer. Dan F. Smith will become Chairman at the time of the TPG investment. Mr. Smith served as Chairman, President and CEO of Lyondell Chemical Company until its acquisition by Basell in 2007, and he is currently the Chairman of the Board of Kraton Polymers. The transaction is expected to close by December 31, 2009.

“TPG’s involvement is a critical step in the evolution of the company. This partnership will support our domestic growth trajectory and help us take advantage of significant international opportunities,” Mr. Erwin said.

Michael MacDougall, a partner at TPG, said, “We firmly believe that Valerus is poised to benefit from the continued development of America’s natural gas resources and the growth in gas production from the country’s prolific shale plays. Valerus is also uniquely positioned to help its customers capitalize upon increased natural gas production internationally. We look forward to partnering with the management team to help it pursue the company’s next phase of growth.”

J.P. Morgan and Tudor, Pickering, Holt & Co. Securities, Inc. were financial advisors to TPG. Vinson & Elkins LLP served as legal counsel to TPG. Valerus was represented by Barclays Capital and King & Spalding LLP.
