May 8, 2009

SEAL BEACH, Calif., May 08, 2009 (BUSINESS WIRE) -- Clean Energy Fuels Corp. (Nasdaq: CLNE) has entered into an agreement to acquire the natural gas fueling station business of Exterran Holdings, Inc. (NYSE: EXH). The acquisition agreement includes natural gas station operations and maintenance (O&M) contracts covering approximately 25 million GGEs (gasoline gallon equivalents) of natural gas fuel on an annual basis for four transit operators (eight fueling facilities).

Transit agencies served include Los Angeles County Metropolitan Transportation Authority ("LACMTA") in Los Angeles CA, which operates the largest clean air bus fleet in the United States; Montgomery County Transit MD; Washington Metropolitan Area Transit Authority ("WMATA") in Washington D.C.; and Massachusetts Bay Transportation Authority ("MBTA") in Boston MA. The acquisition of the LACMTA and MBTA contracts closed effective upon signing of the acquisition agreement. The sale of the contracts with Montgomery County Transit and WMATA is subject to approval of the appropriate transit authorities. The aggregate purchase price for the acquired contracts is approximately $5.9 million, of which approximately $3.2 million was paid upon the closing of the sale of the LACMTA and MBTA contracts.

"Besides the immediate volume and revenue benefits for Clean Energy, this strategic acquisition expands our participation in the transit industry nationwide," said Andrew J. Littlefair, Clean Energy president and CEO. "With more than 20% of the nation's transit buses running on natural gas fuel, we are positioned better to qualify for new contracts, renewals and extensions with leading transit agencies as the deployment of natural gas-fueled buses grows."
