INVESTOR PRESENTATION FEBRUARY 2018

DISCLAIMER Forward-Looking Statements This presentation contains forward-looking statements within the meaning of the Private Securities Litigation Reform Act of 1995. These forward-looking statements reflect our current views with respect to, among other things, future events and our financial performance. These statements are often, but not always, made through the use of words or phrases such as “may,” “might,” “should,” “could,” “predict,” “potential,” “believe,” “expect,” “continue,” “will,” “anticipate,” “contemplate,” “seek,” “estimate,” “intend,” “plan,” “target,” “project,” “would,” “annualized” and “outlook,” or the negative version of those words or other comparable words or phrases of a future or forward-looking nature. These forward-looking statements are not historical facts and are based on current expectations, estimates and projections about our industry, management's beliefs and certain assumptions made by management, many of which, by their nature, are inherently uncertain and beyond our control. Accordingly, we caution you that any such forward-looking statements are not guarantees of future performance and are subject to risks, assumptions, estimates and uncertainties that are difficult to predict. Although we believe that the expectations reflected in these forward-looking statements are reasonable as of the date made, actual results may prove to be materially different from the results expressed or implied by the forward-looking statements. For a discussion of some of the risks and important factors that could affect our future results and financial condition, see our U.S. Securities and Exchange Commission (“SEC”) filings, including, but not limited to, our Annual Report on Form 10-K for the year ended December 31, 2016. Except as required by law, we assume no obligation to update these forward-looking statements or to update the reasons why actual results could differ materially from those anticipated in the forward-looking statements, even if new information becomes available in the future. Use of Non-GAAP Financial Measures The information provided herein includes certain non-GAAP financial measures. We believe that these core measures provide useful information about our operating results and enhance the overall understanding of our past performance and future performance. Although these non-GAAP financial measures are frequently used by stakeholders in the evaluation of a company, they have limitations as analytical tools and should not be considered in isolation or as a substitute for analysis of our results or financial condition as reported under GAAP. Investors should consider our performance and financial condition as reported under GAAP and all other relevant information when assessing our performance or financial condition. The reconciliation of such measures to the comparable GAAP figures are included in the appendix of this presentation. 1

GAAP TO NON-GAAP RECONCILIATION We present net interest income, noninterest income, noninterest expense, net income, earnings per share and the related ratio s described below, on an adjusted, or ‘‘core,’’ basis, each a non-GAAP financial measure. These core measures exclude from the corresponding GAAP measure the impact of certain items that we do not believe are representative of our financial results. We believe that the presentation of these non-GAAP financial measures helps identify underlying trends in our business from period to period that could otherwise be distorted by the effect of certain expenses, gains and other items inc luded in our operating results. Core net interest margin, core return on average total assets and core return on average total stockholders’ equity are non -GAAP financial measures. We compute our core net interest margin as the ratio of core net interest income to average earning assets. We compute our core return on a verage total assets as the ratio of core net income to average total assets. We compute our core return on average total stockholders’ equity as the ratio of core net in come to average stockholders’ equity. Core efficiency ratio is a non-GAAP financial measure. We compute our core efficiency ratio as the ratio of core noninterest expense to the sum of core net interest income and core noninterest income. Return on average tangible stockholders’ equity, core return on average tangible stockholders’ equity, return on average tangible as sets, core return on average tangible assets and tangible stockholders’ equity to tangible assets are non-GAAP financial measures. We compute our return on average tangible stockholders’ equity as the ratio of net income to average tangible stockholders’ equity, which is calculated by subtracting (and thereby effectiv ely excluding) amounts related to the effect of goodwill from our average total stockholders’ equity. We compute our core return on average tangible stockholders’ equity as the ratio of core net income to average tangible stockholders’ equity, which is calculated by subtracting (and thereby effectively excluding) amounts related to the effect of goodwill from our average total stockholders’ equity. We compute our return on average tangible assets as the ratio of net income to average tangible assets, which is calculated by subtracting (and thereby effectively excluding) amounts related to the effect of goodwill from our average total assets. We compute our core r eturn on average tangible assets as the ratio of core net income to average tangible assets. We compute our tangible stockholders’ equity to tangible assets as the ratio of tangible stockholders’ equity to tangible assets, each of which we calculate by subtracting (and thereby effectively excluding) amounts related to our goodwill. We believe that these core measures provide useful information about our operating results and enhance the overall understanding of our past performance and future performance. Although these non-GAAP financial measures are frequently used by stakeholders in the evaluation of a company, they have limitations as analytical tools and should not be considered in isolation or as a substitute for analysis of our results or financial condition as repo rted under GAAP. Investors should consider our performance and financial condition as reported under GAAP and all other relevant information when assessing our performance or financial condition. The following tables provide a reconciliation of these non-GAAP financial measures with their most closely related GAAP measures. 22
