Lake Forest, Illinois, May 30, 2008 – Tenneco Inc. (NYSE: TEN) today announced that the company has finalized a purchase agreement with Delphi Automotive Systems LLC to acquire certain ride control assets and inventory at Delphi’s Kettering, Ohio facility. The closing is effective today.

"The purchase is also a win for the Kettering community and employees since jobs will be maintained that otherwise would be lost. We’re moving ahead with a strong local management team in place with the goal of growing the plant’s book of business."

Tenneco will employ approximately 400 hourly and salaried employees at the Kettering plant. In connection with the purchase agreement, Tenneco has entered into a five-year agreement with the International Union of Electrical Workers (IUE), which will represent the hourly workforce at the facility. The agreement was ratified by the IUE’s rank and file in August 2007.
