News Release: Receives orders for 62 low-emissions bus engines for Asia

Cummins Westport Inc., a joint venture of Cummins Inc. (NYSE:CUM) of Columbus, Indiana, and Westport Innovations Inc. (TSX: WPT) of Vancouver, B.C., announced today that it has received orders for a total of 62 low-emissions natural gas engines for transit service in three cities in Asia.

These orders include both B5.9G-230 horsepower engines and C Gas Plus engines. They represent new market areas for Cummins Westport and follow a previously disclosed order in December for 10 B5.9G engines for the City of Xining, capital of Qinghai Province. All of the engines will be delivered by March 2003. Cummins Westport's largest customer in Asia remains Beijing, which has approximately 2,000 B5.9G engines in transit bus service. The five Asian cities that have purchased Cummins Westport natural gas engines operate a combined total of more than 35,000 transit buses.

"The transit buses in these five cities alone are equivalent to nearly half the entire U.S. transit fleet," says Cummins Westport President Hugh Foden. "With other cities outside of Beijing ordering Cummins Westport engines, our presence across Asia is growing stronger and our geographic diversification efforts are beginning to pay off in sales."

Cummins Inc. is a global power leader in engines, electrical power generation systems and related technologies. Westport Innovations is the leading developer of natural gas fuel systems for diesel engines. Cummins Westport Inc., formed in 2001, develops and markets low-emissions alternative fuel vehicle engines manufactured by Cummins.

Note: This news release contains forward-looking statements about Cummins and Westport business and technology development plans based on the current expectations of management of both companies. Cummins and Westport caution investors that due to risks and uncertainties, actual events may differ materially from current expectations.
