FORWARD-LOOKING STATEMENTS

     This Current Report on Form 8-K contains forward-looking statements within the meaning of federal securities laws. Forward-looking information can be identified through the use of words such as “intend,” “plan,” “project,” “expect,” “anticipate,” “believe,” “estimate,” “contemplate,” “possible,” “point,” “will,” “may,” “should,” “would” and “could.” Forward-looking statements and information are not historical facts, are premised on many factors and assumptions, and represent only management’s expectations, estimates and projections regarding future events. Similarly, these statements are not guarantees of future performance and involve certain risks and uncertainties that are difficult to predict, which may include, but are not limited to, those listed below and the Risk Factors discussed in Item 1A of the Company’s Annual Report on Form 10-K for the year ended December 31, 2010 and in any of the Company’s subsequent SEC filings. The Company intends such forward-looking statements to be covered by the safe harbor provisions for forward-looking statements contained in the Private Securities Litigation Reform Act of 1995, and is including this statement for purposes of invoking these safe harbor provisions. Such forward-looking statements may be deemed to include, among other things, statements relating to the Company’s future financial performance, the performance of its loan portfolio, the expected amount of future credit reserves and charge-offs, delinquency trends, growth plans, regulatory developments, securities that the Company may offer from time to time, and management’s long-term performance goals, as well as statements relating to the anticipated effects on financial condition and results of operations from expected developments or events, the Company’s business and growth strategies, including future acquisitions of banks, specialty finance or wealth management businesses, internal growth and plans to form additional de novo banks or branch offices. Actual results could differ materially from those addressed in the forward-looking statements as a result of numerous factors, including the following:

• negative economic conditions that adversely affect the economy, housing prices, the job market and other factors that may affect the Company’s liquidity and the performance of its loan portfolios, particularly in the markets in which it operates;

• the extent of defaults and losses on the Company’s loan portfolio, which may require further increases in its allowance for credit losses;

• estimates of fair value of certain of the Company’s assets and liabilities, which could change in value significantly from period to period;

• changes in the level and volatility of interest rates, the capital markets and other market indices that may affect, among other things, the Company’s liquidity and the value of its assets and liabilities;

• a decrease in the Company’s regulatory capital ratios, including as a result of further declines in the value of its loan portfolios, or otherwise;

• legislative or regulatory changes, particularly changes in regulation of financial services companies and/or the products and services offered by financial services companies, including those resulting from the Dodd-Frank Wall Street Reform and Consumer Protection Act (the “Dodd-Frank Act”);

• restrictions upon the Company’s ability to market its products to consumers and limitations on its ability to profitably operate our mortgage business resulting from the Dodd-Frank Act;

• increased costs of compliance, heightened regulatory capital requirements and other risks associated with changes in regulation and the current regulatory environment, including the Dodd-Frank Act;

• changes in capital requirements resulting from the Basel II and III initiatives;

• increases in the Company’s Federal Deposit Insurance Corporation (“FDIC”) insurance premiums, or the collection of special assessments by the FDIC;

• losses incurred in connection with repurchases and indemnification payments related to mortgages;

• competitive pressures in the financial services business which may affect the pricing of the Company’s loan and deposit products as well as its services (including wealth management services);

• delinquencies or fraud with respect to the Company’s premium finance business;

• failure to identify and complete favorable acquisitions in the future or unexpected difficulties or developments related to the integration of recent or future acquisitions;

• unexpected difficulties and losses related to FDIC-assisted acquisitions, including those resulting from the Company’s loss-sharing arrangements with the FDIC;

• credit downgrades among commercial and life insurance providers that could negatively affect the value of collateral securing the Company’s premium finance loans;

• any negative perception of the Company’s reputation or financial strength;

• the loss of customers as a result of technological changes allowing consumers to complete their financial transactions without the use of a bank;

• the ability of the Company to attract and retain senior management experienced in the banking and financial services industries;

• the Company’s ability to comply with covenants under its securitization facility and credit facility;

• unexpected difficulties or unanticipated developments related to the Company’s strategy of de novo bank formations and openings, which typically require over 13 months of operations before becoming profitable due to the impact of organizational and overhead expenses, startup phase of generating deposits and the time lag typically involved in redeploying deposits into attractively priced loans and other higher yielding earning assets;

• changes in accounting standards, rules and interpretations and the impact on the Company’s financial statements;

• adverse effects on the Company’s operational systems resulting from failures, human error or tampering;

• significant litigation involving the Company; and

• the ability of the Company to receive dividends from its subsidiaries.

     Therefore, there can be no assurances that future actual results will correspond to these forward-looking statements. The reader is cautioned not to place undue reliance on any forward-looking statement made by or on behalf of the Company. Any such statement speaks only as of the date the statement was made or as of such date that may be referenced within the statement. The Company undertakes no obligation to release revisions to these forward-looking statements or reflect events or circumstances after the date such statement was made. Persons are advised, however, to consult further disclosures management makes on related subjects in its reports filed with the Securities and Exchange Commission and in its press releases.
