    TENNECO ANNOUNCES POTENTIAL ACQUISITION OF SUSPENSION BUSINESS OF GRUPPO
                                    MARZOCCHI

Lake Forest, IL, Brussels, Belgium, July 10, 2008 - Tenneco Inc. (NYSE: TEN)
announced today that the company has entered into a preliminary agreement to
purchase the suspension business of Gruppo Marzocchi, an Italian-based worldwide
leader in supplying suspension technology in the two-wheeler market.

The agreement announced today is the initial step in the purchase process. A
final agreement and closing on a potential purchase of Marzocchi's suspension
business is dependent on a number of conditions and the legally-required
consultation with the works councils representing Marzocchi employees. Those
consultations will begin immediately.

This acquisition would be made through Tenneco's assumption of the debt
associated with Marzocchi's suspension business, which was approximately $15
million as of April 30, 2008.

An acquisition by Tenneco of Marzocchi's suspension business would leverage the
brand, technology and product synergies of the two companies, providing
customers with integrated suspension systems (forks, shock absorbers and
elastomers) for motorcycles and other applications.

Tenneco is a $6.2 billion global manufacturing company with headquarters in Lake
Forest, Illinois and approximately 21,000 employees worldwide. Tenneco is one of
the world's largest designers, manufacturers and marketers of emission control
and ride control products and systems for the automotive original equipment
market and the aftermarket. Tenneco markets its products principally under the
Monroe(R), Walker(R), Gillet(TM) and Clevite(R)Elastomer brand names.
