           TENNECO AUTOMOTIVE ANNOUNCES RECEIPT OF REQUISITE CONSENTS
                        TO AMEND INDENTURE GOVERNING THE
                   11-5/8% SENIOR SUBORDINATED NOTES DUE 2009

Lake Forest, Illinois, May 13, 2004 - Tenneco Automotive (NYSE: TEN) announced
today, pursuant to its previously announced tender offer and consent
solicitation (the "Offer") for any and all of its $500,000,000 aggregate
principal amount of 11-5/8% Senior Subordinated Notes due 2009, CUSIP Number
880349AA3 (the "Notes"), that it has received the requisite consents to adopt
the proposed amendments to the indenture governing the Notes. Adoption of the
proposed amendments required the consent of holders of at least a majority of
the aggregate principal amount of the outstanding Notes under the indenture. The
proposed amendments will eliminate substantially all of the restrictive
covenants and certain events of default in the indenture and the Notes.

The Company, the Guarantors and the Bank of New York, in its capacity as Trustee
under the indenture, executed the supplemental indenture adopting the proposed
amendments on May 13, 2004. The provisions of the supplemental indenture will
not become operative until Tenneco Automotive accepts for payment Notes tendered
pursuant to the Offer that represent at least a majority of the aggregate
principal amount of Notes outstanding under the indenture, at which time the
provisions of the supplemental indenture automatically become operative. Once
the provisions become operative they will be binding upon the holders of the
Notes, including holders who do not tender their Notes in the Offer.

Tenneco Automotive has engaged Banc of America Securities LLC and J.P. Morgan
Securities Inc. to act as co-dealer managers in connection with the tender offer
and solicitation agents in connection with the consent solicitation. Questions
