                           TENNECO AUTOMOTIVE LAUNCHES
          TENDER OFFER AND CONSENT SOLICITATION IN CONNECTION WITH ITS
                   11-5/8% SENIOR SUBORDINATED NOTES DUE 2009

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 $1095.50 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 $1065.50 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
