Tenneco Inc. To Withdraw Pacific Exchange Listing

December 11, 2006

LAKE FOREST, ILLINOIS, DECEMBER 11, 2006 – Tenneco Inc. (NYSE: TEN) today announced plans to withdraw the listing of its common stock from NYSE Arca, Inc., formerly the Pacific Exchange. Tenneco's common stock will continue to be listed on the New York Stock Exchange, the Chicago Stock Exchange and the London Stock Exchange.

Tenneco has decided to withdraw its listing from NYSE Arca to streamline operations and eliminate duplicative administrative requirements inherent with dual listings as a result of the NYSE Group's recent merger with Archipelago Holdings, the parent company of NYSE Arca. The withdrawal is expected to be effective within the next month.

Tenneco does not believe that withdrawing its listing from NYSE Arca will have any impact on the liquidity of its stock
