LAKE FOREST, ILLINOIS, NOVEMBER 10, 2004 - Tenneco Automotive (NYSE: TEN) announced today that the company has been selected by Ford Motor Company to supply the full exhaust system on Ford's Heavy Duty F-Series diesel pick-up trucks that will launch in 2006. The company will supply hot and cold-end exhaust components including the diesel oxidation catalyst, diesel particulate filter and tuning devices.

Previously, Tenneco Automotive had been named the full service exhaust supplier for the gasoline version of the F-Series Super Duty trucks, which will also launch in 2006. Together, these contracts represent the largest single new business win ever for Tenneco Automotive. The company also supplies the cold-end exhaust system on Ford's F-Series light duty pick-up truck and is responsible for hot and cold-end system integration.

"We are extremely proud of our partnership with Ford and our performance in launching and supplying exhaust systems tailored to the F-Series platforms. We are especially pleased to win the heavy duty business, which gives us another opportunity to showcase our latest diesel technologies," said Mark P. Frissora, chairman and CEO, Tenneco Automotive. "We are growing our book of business as we continue to serve customers around the globe with innovative products and outstanding service, from the earliest design stages through the launch of our products on new vehicles."
