Reconciliations of these non-GAAP financial measures to the comparable GAAP measure are included in this presentation.

* Including noncontrolling interests.

EBIT, earnings before interest expense, income taxes and noncontrolling interests (GAAP measure) 379 281

Depreciation & amortization of other intangibles 207 216

Total EBITDA* $ 586 $ 497

EBITDA* represents earnings before interest expense, income taxes, noncontrolling interests and depreciation and amortization. EBITDA* is not a calculation based upon generally accepted accounting principles. The amounts included in the EBITDA* calculation, however, are derived from amounts included in the historical statements of income. In addition, EBITDA* should not be considered as an alternative to net income (loss) attributable to Tenneco Inc. or operating income as an indicator of the company’s operating performance, or as an alternative to operating cash flows as a measure of liquidity. Tenneco has presented EBITDA* because it regularly reviews EBITDA* as a measure of the company’s performance. In addition, Tenneco believes that its security holders utilize and analyze its EBITDA* for similar purposes. Tenneco also believes EBITDA* assists investors in comparing a company’s performance on a consistent basis without regard to depreciation and amortization, which can vary significantly depending upon many factors. However, the EBITDA* measure presented may not always be comparable to similarly titled measures reported by other companies due to differences in the components of the calculation. * Including noncontrolling interests. 36 Financial Accomplishments – Reconciliation of Non-GAAP Results

(1) Generally Accepted Accounting Principles (2) Tenneco presents the above reconciliation of GAAP to non-GAAP earnings measures primarily to reflect the results of 2011 and 2010 in a manner that allows a better understanding of the results of operational activities separate from the financial impact of decisions made for the long-term benefit of the company. Adjustments similar to the ones reflected above have been recorded in earlier periods, and similar types of adjustments can reasonably be expected to be recorded in future periods. Using only the non-GAAP earnings measures to analyze earnings would have material limitations because its calculation is based on the subjective determinations of management regarding the nature and classification of events and circumstances that investors may find material. Management compensates for these limitations by utilizing both GAAP and non-GAAP earnings measures reflected above to understand and analyze the results of the business. * Including noncontrolling interests. 37 Adjusted EBIT as a Percentage of Value-Add Revenue – Reconciliation of Non-GAAP Results

FY 11 FY 10

Total revenue $ 7,205 $ 5,937

Value-add revenue $ 5,527 $ 4,653

Adjusted EBIT as a percentage of value-add revenue(1) 7.2% 6.6%

(1) Tenneco presents the above reconciliation of revenues in order to reflect value-add revenue. Substrate sales include precious metals pricing, which may be volatile. Substrate sales occur when, at the direction of its OE customers, Tenneco purchases catalytic converters or components thereof from suppliers, uses them in its manufacturing processes and sells them as part of the completed system. While Tenneco original equipment customers assume the risk of this volatility, it impacts reported revenue. Excluding substrate sales removes this impact. Further, presenting adjusted EBIT as a percentage of value-add revenue assists investors in evaluating our company’s operational performance without the impact of such substrate sales.
