Forward-Looking Statement This presentation contains certain forward-looking statements within the meaning of the Private Securities Litigation Reform Act of 1995. These statements include, but are not limited to, statements relating to Old National's financial condition, asset and credit quality trends, capital, liquidity and the financial benefits and other effects of the acquisition of certain assets and assumption of certain liabilities of Integra Bank from the FDIC. Forward-looking statements can be identified by the use of the words "anticipate," "believe," "expect," "intend," "could" and "should," and other words of similar meaning. Forward-looking statements express management's current expectations or forecasts of future events and, by their nature, are subject to risks and uncertainties and there are a number of factors that could cause actual results to differ materially from those in such statements. Factors that might cause such a difference include, but are not limited to; market, economic, operational, liquidity, credit and interest rate risks associated with Old National's business, competition, government legislation and policies (including the impact of the Dodd-Frank Wall Street Reform and Consumer Protection Act and the regulations to be issued thereunder), ability of Old National to execute its business plan, including the integration of the acquired Integra Bank assets and liablities, changes in the economy which could materially impact credit quality trends and the ability to generate loans and gather deposits, failure or circumvention of Old National's internal controls, failure or disruption of our information systems, significant changes in accounting, tax or regulatory practices or requirements, new legal obligations or liabilities or unfavorable resolutions of litigations, other matters discussed in this presentation and other factors identified in the Company's Annual Report on Form 10-K and other periodic filings with the Securities and Exchange Commission. These forward-looking statements are made only as of the date of this presentation, and Old National undertakes no obligation to release revisions to these forward-looking statements to reflect events or conditions after the date of this presentation.

Non-GAAP Financial Measures These slides contain non-GAAP financial measures. For purposes of Regulation G, a non-GAAP financial measure is a numerical measure of the registrant's historical or future financial performance, financial position or cash flows that excludes amounts, or is subject to adjustments that have the effect of excluding amounts, that are included in the most directly comparable measure calculated and presented in accordance with GAAP in the statement of income, balance sheet or statement of cash flows (or equivalent statements) of the issuer; or includes amounts, or is subject to adjustments that have the effect of including amounts, that are excluded from the most directly comparable measure so calculated and presented. In this regard, GAAP refers to generally accepted accounting principles in the United States. Pursuant to the requirements of Regulation G, Old National Bancorp has provided reconciliations within the slides, as necessary, of the non-GAAP financial measure to the most directly comparable GAAP financial measure.
