Forward-Looking Statements This presentation may contain forward-looking statements with respect to the financial condition, results of operations, trends in lending policies, plans, objectives, future performance or business of the Company. Forward-looking statements are generally identifiable by the use of words such as “anticipate,” “believe,” “could,” “estimate,” “expect,” “intend,” “may,” “pending,” “plan,” “preliminary,” “should,” “will,” “would” or other similar expressions. Forward-looking statements are not a guarantee of future performance or results, are based on information available at the time the statements are made and involve known and unknown risks, uncertainties and other factors that could cause actual results to differ materially from the information in the forward-looking statements. Factors that may cause such differences include: failures or breaches of or interruptions in the communications and information systems on which we rely to conduct our business; failure of our plans to grow our commercial real estate, commercial and industrial, public finance and healthcare finance loan portfolios; competition with national, regional and community financial institutions; the loss of any key members of senior management; fluctuations in interest rates; general economic conditions; risks relating to the regulation of financial institutions; and other factors identified in reports we file with the U.S. Securities and Exchange Commission.

Non-GAAP Financial Measures This presentation contains financial information determined by methods other than in accordance with U.S. generally accepted accounting principles (“GAAP”). Non-GAAP financial measures, specifically adjusted net income, adjusted diluted earnings per share, average tangible common equity, adjusted return on average assets, return on average tangible common equity (“ROATCE”), adjusted ROATCE, tangible common equity (“TCE”), tangible assets (“TA”), tangible book value (“TBV”) per common share, tangible common equity to tangible assets, net interest margin – FTE, adjusted noninterest expense/average assets and adjusted efficiency ratio are used by the Company’s management to measure the strength of its capital and analyze profitability, including its ability to generate earnings on tangible capital invested by its shareholders. Although management believes these non-GAAP measures are useful to investors by providing a greater understanding of its business, they should not be considered a substitute for financial measures determined in accordance with GAAP, nor are they necessarily comparable to non-GAAP financial measures that may be presented by other companies. Reconciliations of these non-GAAP financial measures to the most directly comparable GAAP financial measures are included in the table at the end of this presentation under the caption “Reconciliation of Non-GAAP Financial Measures.” 4
