March 19, 2007

LAKE FOREST, ILLINOIS, MARCH 19, 2007 – Tenneco Inc. (NYSE: TEN) announced today that it completed its transaction to refinance its existing $831 million senior credit facility with a new $830 million senior credit facility. The transaction enhances the company's financial flexibility by replacing its previous Term B facility with an expanded revolver; extending the expiration of its revolving line of credit to March 2012; extending the maturities of its term loan facility; and enhancing covenant flexibility.

The new senior credit facility includes a 5-year revolving line of credit of $550 million; a 5-year term loan A facility of $150 million; and a 7-year synthetic letter of credit facility of $130 million, which can also be used as a revolving line of credit.

The company used the initial proceeds of the financings described above to repay approximately $356 million of outstanding term loans under its existing credit facility and to replace the $155 million synthetic letter of credit facility and the $320 million revolving line of credit provided under its existing senior credit facility. The $320 million revolving line of credit was set to expire in December 2008.

"We are extremely pleased with the terms of our new credit facility, which reflect the lending community's growing confidence in Tenneco as a result of the company's strengthening performance over the last four years, as well as in our strategic growth and cost management plans going forward," said Gregg Sherrill, chairman and CEO, Tenneco Inc. "In addition to expanding our revolver, this new facility will reduce our annual interest expense by more than $4 million annually. Additionally, we secured more favorable covenant terms, including the elimination of our fixed charge covenant, which will provide Tenneco the flexibility needed to help it achieve its long-term plans more quickly."
