Tenneco Automotive Announces Receipt Of Requisite Consents To Amend Indenture Governing The 11-5/8% Senior Subordinated Notes Due 2009

May 13, 2004

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.

Morgan Securities Inc. to act as co-dealer managers in connection with the tender offer and solicitation agents in connection with the consent solicitation.
