Westport and Clean Energy Co-Marketing Program Helps

Companies Ramp Up Natural Gas Transportation Solutions

March 19, 2013

LOUISVILLE, KY -- Heavy-duty trucking customers seeking optimal on-board fuel storage,
high-performance natural gas engines, and reliable fueling can benefit from a new
joint marketing program by Westport Innovations Inc. (TSX:WPT/NASDAQ:WPRT) and Clean
Energy Fuels Corp. (NASDAQ:CLNE) that was announced today in Louisville, Kentucky,
home of the Mid-America Truck Show (MATS).

To encourage the use of natural gas vehicles and the establishment of the growing
fueling infrastructure across North America, the companies will bundle the Westport(TM)
LNG Tank System -- optimized for use with the Cummins Westport ISL G or the new
Cummins Westport ISX12 G engines -- and a long-term fuel contract with Clean Energy
into a package for qualified customers.

The program is designed to achieve the following goals:


* Deliver an attractive payback for truck customers utilizing the Cummins Wesport
ISL G or ISX12 G engine with a Westport LNG Tank System
* Establish availability of long-term refueling contracts at a savings to diesel
 for Clean Energy customers
* Establish a strong market for natural gas trucks with additional conveniently
located liquefied natural gas (LNG) fueling stations for customers

"We know that customers are looking for efficient solutions that will allow them
 to take advantage of the long term savings and environmental benefits that natural
gas will bring for their fleets," said James Harger, Chief Marketing Officer, Clean
Energy. "Collectively, we can help get them on the road quickly and economically,
while building out America's Natural Gas Highway�."

Clean Energy has already completed 70 natural gas fueling stations as part of America's
Natural Gas Highway�, which will allow long-haul trucks to travel across all major
corridors through the United States, and has more stations in development.

The Westport LNG Tank System is currently available in limited quantities for customer
trials, and can be ordered now with commercial quantities available in September
 2013. It operates on either cold or warm LNG and is expected to provide customers
with the ability to fuel even the largest spark-ignited engines on a single or dual
120 gallon tank, and deliver extended range and hold times while operating on cold
LNG. Attendees to MATS are invited to view the Westport LNG Tank System which will
be on display at the Clean Energy booth.

"The interest and demand is high for both the new Westport LNG Tank System and the
Cummins Westport ISX12 G," said Steve Anderson, Vice President Business Development,
Westport. "This collaborative program allows us to give customers a good opportunity
to invest in the most advanced natural gas engine and fuel storage technology."
