                 TENNECO ANNOUNCES NEW AFTERMARKET BUSINESS AND
                    SECOND QUARTER RESTRUCTURING INITIATIVES

     -  Awarded new aftermarket business with revenue of $8 million annually
     -  Restructuring projects estimated to generate $10 million in annual
        savings

Lake Forest, Illinois, June 19, 2006 - Tenneco Inc. (NYSE: TEN) announced today
that the company has won new aftermarket business from 13 aftermarket customers
in North America, expected to generate approximately $8 million in revenue
annually. Initial orders are expected to generate $4 million in revenue in the
second quarter of 2006. The company's targeted sales efforts have established
new long-term relationships with customers for its ride control, exhaust and
brake products. Tenneco expects to record charges associated with changing over
these new customers of approximately $6 million in the second quarter of 2006.

Tenneco also announced that the company estimates it will record pre-tax
restructuring and restructuring related charges of approximately $15 million for
projects to improve the company's distribution and manufacturing operations
globally. The company estimates it will record approximately $8 million of the
charges during the second quarter of 2006 and an additional $7 million over the
next four quarters. The company estimates these actions will result in annual
savings of approximately $10 million when completed.

"We continue to generate top-line growth while reducing costs and improving our
operational efficiency," said Mark P. Frissora, chairman, CEO and president,
Tenneco. "Our ongoing restructuring activities are driven by our successful Lean
manufacturing and Six Sigma initiatives and our continuous efforts to optimize
our global distribution and manufacturing footprint."

The second quarter restructuring costs are for restructuring activities taking
place at about 20 locations worldwide, aimed at improving efficiency, reducing
costs and sizing operations to better reflect local market conditions. The
restructuring charges include an estimated $4 million for severance costs and
other benefits related to employee layoffs and $4 million for other
restructuring and related costs including closing plants, plant relocations and
asset impairments. Tenneco estimates that approximately 80% of these charges
will be paid in cash. The company also estimates that roughly $7 million of the
annual savings are the result of efficiency improvements and cost reductions and
$3 million driven by activities to size operations to local market conditions.

to reflect lower OE production in Australia; consolidation at its Etain, France
facility; closing of the Sterling Heights, Michigan just-in-time facility;
discontinuation of the company's Martorell, Spain just-in-time operations;
consolidation and sale of the company's Harrisonburg, Virginia aftermarket

Tenneco will conduct any workforce reductions in compliance with all legal and
contractual requirements including obligations to consult with workers'
councils, union representatives and others.
