Clean Energy Signs Agreement to Acquire Northstar,
Advanced LNG Technology Leader

— Major Liquefied Natural Gas (LNG) Fueling Infrastructure Firm Will Help
Clean Energy Build Out Natural Gas Fueling Infrastructure Nationwide —

Seal Beach, Calif. (December 8, 2010) — Clean Energy Fuels Corp. (Nasdaq: CLNE) has entered into a Securities Purchase Agreement to acquire Wyoming Northstar Incorporated and affiliates (“Northstar”) for an aggregate purchase price of approximately $10.9 million in cash. Approximately $7.4 million will be paid at closing with the balance paid in equal installments on each yearly anniversary date beginning in 2011 and ending in 2015. Clean Energy will also pay retention bonuses not to exceed $4.0 million in the aggregate over the four-year period following closing.

Northstar is the recognized leader in LNG/LCNG (liquefied to compressed natural gas) fueling system technologies, including the manufacture of one of only two weights-and-measures certified LNG dispensers. It has provided LNG station design, construction, operations and maintenance for major clients, and has worked closely with Clean Energy for several years.

“Having Northstar, the premier LNG station provider, in our group will greatly enhance our ability to build out the growing natural gas fueling infrastructure in the United States,” said Andrew J. Littlefair, Clean Energy’s President and CEO. “Our plan envisions a fueling infrastructure serving major goods movement and trucking corridors nationwide.”

Clean Energy recently announced an agreement with Pilot Flying J Travel Centers to build, own and operate public access, LNG fueling facilities at agreed-upon Pilot Flying J truck travel centers nationwide. Pilot Flying J operates over 550 truck travel centers in 43 states and six Canadian provinces.

Littlefair added, “On the international front, growing interest in LNG fueling in markets such as China, where we have a strong developing presence through our subsidiary, IMW Industries, may provide infrastructure opportunity as well.”
