ITEM 8.01 OTHER EVENTS

On July 30, 2008 Tenneco Inc. 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. 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.

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.

A copy of the company's press release is attached hereto as Exhibit 99.1 and is
incorporated herein by reference.
