 Forward Looking Statements & Other Information              Forward Looking Statements   This presentation contains certain forward-looking statements within the safe harbor rules of the federal securities laws.   These statements generally relate to COB’s financial condition, results of operations, plans, objectives, future   performance or business. They usually can be identified by the use of forward-looking terminology, such as “believes,”   “expects,” or “are expected to,” “plans,” “projects,” “goals,” “estimates,” “may,” “should,” “could,” “would,” “intends to,”   “outlook” or “anticipates,” or variations of these and similar words, or by discussions of strategies that involve risks and   uncertainties. Forward looking statements are subject to risks and uncertainties, including but not limited to, those risks   described in COB’s Annual Report on Form 10-K for the year ended December 31, 2013 under the section entitled   “Item 1A, Risk Factors,” and in the Quarterly Reports of Form 10-Q and other reports that are filed by COB with the   Securities and Exchange Commission. You are cautioned not to place undue reliance on these forward-looking   statements, which are subject to numerous assumptions, risks and uncertainties, and which change over time. These   forward-looking statements speak only as of the date of this presentation. Actual results may differ materially from   those expressed in or implied by any forward looking statements contained in this presentation. We assume no duty to   revise or update any forward-looking statements, except as required by applicable law.   Non-GAAP Financial Measures   In addition to the results of operations presented in accordance with Generally Accepted Accounting Principles (GAAP),   COB management uses and this presentation contains or references, certain non-GAAP financial measures, such as   core earnings and core noninterest expense to average assets and tangible book value. COB believes these non-   GAAP financial measures provide information useful to investors in understanding our underlying operational   performance and our business and performance trends as they facilitate comparisons with the performance of others in   the financial services industry; however, these non-GAAP financial measures should not be considered an alternative   to GAAP. The non-GAAP financial measures contained within this presentation should be read in conjunction with the   audited financial statements and analysis as presented in COB’s Annual Report on Form 10-K as well as the unaudited   financial statements and analyses as presented in COB’s Quarterly Reports on Form 10-Q. A reconciliation of non-   GAAP measures to the most directly comparable GAAP measure is included within tables in the presentation or with   the appendix to this presentation.     2
