Reconciliations

In addition to the results reported in accordance with accounting principles generally accepted in the United States ("GAAP") included in this report, the company has provided information regarding certain non-GAAP financial measures. See Tenneco's Fourth Quarter and Full-Year 2010 Financial Results filed on Form 8-K on February 3, 2011 for a reconciliation of EBIT to Adjusted EBIT and Net Income to Adjusted Net Income. Additionally, see page 14 of this report for a reconciliation of Net Income to EBITDA*, EBITDA* to Adjusted EBITDA* and Net Debt/Adjusted EBITDA*. We present debt net of cash balances because management believes it is a useful measure of our credit position and progress toward reducing leverage. The calculation is limited in that we may not always be able to use cash to repay debt on a dollar-per-dollar basis.
