News Release: Cummins Westport enters Egyptian market

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 entered the Egyptian market with Egyptian Automotive Company, the leading bus manufacturer in Egypt.

The market entry begins with a display of the low-emissions B Gas Plus natural engine in a 40-foot Egyptian Automotive transit bus at the Cairo International Fair in Egypt from March 19 to March 28, 2003. The fair, the largest in the Middle East, will provide important exposure for this new, advanced Cummins Westport 5.9-liter natural gas engine in a region with strong future potential. The bus and engine, which were ordered by Cairo Transit Authority, will go into service in Cairo after the fair. The Cummins distributor responsible for the order is Egyptian International Motors of Cairo.

'With natural gas reserves more than double its petroleum reserves, Egypt is eager to reduce its reliance on diesel and to move to natural gas,'said Greg Young, Cummins Westport General Manager for Europe, Middle East, and Africa. 'The presence of this bus in Cairo and its subsequent use with Cairo Transit will be a high-profile showcase for the B Gas Plus engine in the Middle East. Once in operation, we are confident the engine will prove itself capable of handling Egypt's extreme operating conditions and we look forward to expanding our business in this area.'

Cairo, a city of approximately 16 million people, has significant air quality issues. The United States government, through USAID, funds the Cairo Air Improvement Project (CAIP), which monitors air quality and funds air quality improvement projects. One of CAIP's key initiatives is encourage Cairo's two largest transit agencies, Cairo Transit Authority and the Greater Cairo Bus Company, to switch from older diesel fueled buses to new low- emissions buses. Cummins Westport natural gas engines are significantly cleaner than the 3,500 diesel buses operated by these two transit fleets.

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. The B Gas Plus is manufactured by Cummins at a factory in Rocky Mount, North Carolina.

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.
