July 30, 2008
Tenneco to supply emission control systems to help address future diesel regulations
Lake Forest, Illinois, July 30, 2008 - Tenneco Inc. (NYSE: TEN) today announced that it has become a global diesel emission control system integration supplier to Caterpillar Inc., the world's leading manufacturer of construction and mining equipment, and diesel engines. In this role, Tenneco will work with Caterpillar to develop and produce diesel engine aftertreatment systems for Caterpillar engines. These aftertreatment systems, along with Caterpillar’s leading engine emissions reduction technology, will be used globally to meet stricter diesel emissions regulations that phase in beginning early in the next decade.

Tenneco will collaborate with Caterpillar to ensure that the right technologies are in place to support the company’s aftertreatment strategies. Both companies have already begun development work for these programs.

"We are extremely excited to work with Caterpillar in helping address its global emission control needs going forward," said Gregg Sherrill, Chairman and CEO, Tenneco. "We plan to leverage our industry-leading advanced technology and our unmatched global engineering and manufacturing footprint to support Caterpillar in its relentless drive to provide customers with innovative products worldwide."

Earlier this year, Tenneco announced that it projects it will achieve an average compounded annual OE revenue growth rate of 11% to 13% between 2008 and 2012, primarily driven by tightening emission control regulations globally. The projection reflects the new business announced today and other new OE business recently awarded to Tenneco, some of which has not yet been announced.

Tenneco’s global emissions operations include 48 emission control manufacturing facilities and four global engineering centers devoted to emission control engineering and advanced technology. The company’s engineering capabilities and broad range of emission control products and systems help vehicle manufacturers address increasingly stringent emissions and noise regulations, the drive for better fuel efficiency and the emission control demands of diesel and other alternative fuel and hybrid vehicles.
