In addition to the information set forth on slide 7, Tenneco’s OE revenue projections are based on the information set forth under “Outlook” in Item 7 – “Management’s Discussion and Analysis of Financial Condition and Results of Operations” as set forth in Tenneco’s Annual Report on Form 10-K for the year ended December 3 1, 2009. Please see that disclosure for further information. Key additional assumptions and limitations described in that disclosure include:

• Tenneco’s revenue projections are as of February 20 10. Tenneco provides revenue projections annually and does not intend to update these projections until February 20 11 .

• Revenue projections are based on original equipment manufacturers’ programs that have been formally awarded to the company; programs where the company is highly confident that it will be awarded business based on informal customer indications consistent with past practices; Tenneco’s status as supplier for the existing program and its relationship with the customer; and the actual original equipment revenues achieved by the company for each of the last several years compared to the amount of those revenues that the company estimated it would generate at the beginning of each year.

• Revenue projections are based on the anticipated pricing of each program over its life.

• Revenue projections assume a fixed foreign currency value. This value is used to translate foreign business to the U.S. dollar.

• Revenue projections are subject to increase or decrease due to changes in customer requirements, customer and consumer preferences, the number of vehicles actually produced by our customers, pricing and foreign currency.
