VANCOUVER, June 28, 2013 /PRNewswire/ – Westport Innovations Inc. (TSX:WPT /
NASDAQ:WPRT), the global leader in natural gas engines, today announced
that it has acquired BAF Technologies, Inc. (BAF) and its subsidiary,
ServoTech Engineering, Inc. (ServoTech), subsidiaries of Clean Energy
Fuels Corp. (NASDAQ:CLNE) for $25 million in Westport stock. Westport
and Clean Energy also announced a $5 million joint marketing and sales
program.

Westport believes that the amalgamation will create the largest product
portfolio and largest market presence in the North American light duty
natural gas vehicle (NGV) space. Specifically, Westport secures its
position as Ford’s largest partner under the Qualified Vehicle Modifier
(QVM) program with over 10 products and approximately 150 Ford
authorized dealerships. The transaction allows both Westport and Clean
Energy to focus on the significant growth opportunities as natural gas
emerges as a global fuel for transportation.

“We welcome the BAF and ServoTech teams to Westport,” said Ian Scott,
Executive Vice President of Westport. “BAF has established a strong
portfolio of natural gas vehicle products and customers over the past
decade. With natural gas increasingly seen as a major transportation
fuel around the world, we believe the combination of these new teams’
market experience and Westport’s technologies, scalable manufacturing
processes and quality control systems will help create the type of
products needed to deliver an OEM-quality vehicle experience to our
customers.”

BAF supports clients with vehicle conversions through the Ford QVM
program and aftermarket conversion products, alternative fuel systems,
application engineering, service and warranty support. ServoTech offers
a total engineering solution from initial concept phase to prototype
hardware and final prove-out, including design and development of
electronic products, software development, automotive exhaust
simulation and testing, spark-ignition gasoline and diesel emissions
technology, and offers technical training and education in a variety of
subject areas.

Currently, Westport exclusively installs the natural gas Westport WiNG™
Power System on the Ford F-250 through F-550 series at its assembly
center in Louisville, KY. This acquisition increases Westport’s product
range with the Ford line to include transit, cargo shuttle and taxi
vehicles and dedicated natural gas vehicles for markets such as
California. BAF has been producing a broad list of natural gas vehicle
conversions for more than a decade and recently produced its 20,000^th compressed natural gas (CNG) vehicle conversion. Westport will continue
to install the Westport WiNG Power System and the increased volume of
orders expected through BAF will create economies of scale, and the BAF
network will allow more flexibility in producing speciality
configurations.

Transaction highlights include:

• $25 million payable in shares of Westport’s common stock on closing at a
  price of $30.62 based on a 10 day volume weighted average, subject to
  adjustments

BAF & ServoTech highlights:

• Trailing 12 months revenue of $20.9 million to April 30, 2013
• Long list of Ford QVM products including but not limited to:

• Ford Transit Connect (EPA approved, CARB pending)
• Ford E-250/350 (EPA & CARB approved)
• Ford E-450/550 (EPA & CARB approved)
• Ford F-250/350 (EPA & CARB approved)
• Ford F-450/550/650 (EPA & CARB approved)
• Ford F-59 (EPA & CARB approved)

Unique capabilities, deep industry experience and knowledge

As a qualified calibration modifier (QCM), ServoTech has preferential
access to Ford engine controls. ServoTech also brings a substantial
technology portfolio around diesel emissions control, diesel dual-fuel
operation and other alternative fuels capabilities.

ServoTech engineering center is in close proximity to Westport’s Detroit
office

“We are extremely pleased with our original investment in BAF and the
growth it has achieved over the last five years,” said Andrew J.
Littlefair, President and CEO, Clean Energy. “This is a great
opportunity for Clean Energy to sharpen our focus on fuel solutions as
the market for NGV’s quickly builds momentum. Westport will deliver
great products, and we at Clean Energy will build the fuel
infrastructure to fuel the vehicles. Our new marketing partnership
expands our long-standing relationship and alliance as we worked
together over the past decade.”

Westport Enters New Marketing Agreement with Clean Energy
Westport has committed $5 million to a new co-marketing program aimed at
increasing the natural gas vehicle market, and will allow Westport to
provide purchase incentives for fleets, including fuel credits, and
includes a commitment from Clean Energy to purchase Westport products.
