Tenneco Automotive Inc. (ticker: TEN, exchange: New York Stock Exchange) News Release

April 30, 2004


LAKE FOREST, ILLINOIS, APRIL 30, 2004 - Tenneco Automotive (NYSE: TEN) announced today that it has commenced a cash tender offer and consent solicitation for its $500,000,000 aggregate principal amount of 11-5/8% Senior Subordinated Notes due 2009.

Tenneco Automotive is launching this tender offer and consent solicitation as part of its transaction announced on April 16, 2004, designed to reduce the company's leverage and annual interest expense.

The offer will expire at 12:00 midnight, New York City time, on Thursday, May 27, 2004, unless extended or earlier terminated. Holders tendering their notes will be required to consent to certain proposed amendments to the indenture governing the notes, which will, among other things, eliminate substantially all of the restrictive covenants, amend the satisfaction and discharge provisions and eliminate certain events of default provisions in the indenture. The consent solicitation will expire at 5:00 p.m. New York City time, on Thursday, May 13, 2004, unless extended or earlier terminated.

Note holders who validly tender their notes before the consent solicitation expires will receive the total consideration of $1,095.50 per $1,000 principal amount of notes. The total consideration includes a consent payment of $30.00 per $1,000 principal amount of notes. Note holders who validly tender their notes after the consent solicitation expires and before the offer expires will receive as payment for the notes $1,065.50 per $1,000 principal amount of notes, which is the total consideration less the $30.00 per $1,000 consent payment. In either case, note holders who validly tender their notes will be paid accrued and unpaid interest up to, but not including, the date of payment for the notes.

The offer is subject to meeting certain conditions, including the company's receipt of tenders of notes representing a majority of the principal amount of the notes outstanding, execution of a supplemental indenture incorporating the proposed amendments, consent of the company's senior bank lenders to permit the consent solicitation on the terms proposed and the receipt of financing on terms acceptable to Tenneco Automotive in an amount sufficient to complete the offer. The terms of the offer are described in Tenneco Automotive's Offer to Purchase and Consent Solicitation Statement, dated April 30, 2004, which may be obtained from Global Bondholder Services, at (866) 873-7700 (US toll-free) or (212) 430-3774.
