In addition, under the Merger Agreement, each outstanding share of preferred stock issued by Citizens South to the United States Department of the Treasury in connection with Citizens South’s participation in the Small Business Lending Fund will be converted into substantially identical shares of Park Sterling preferred stock.

Cautionary Statement Regarding Forward-Looking Statements

This current report contains, and Park Sterling and Citizens South and their respective management may make, certain statements that constitute “forward-looking statements” within the meaning of the Private Securities Litigation Reform Act of 1995. These statements can be identified by the fact that they do not relate strictly to historical or current facts and often use words such as “may,” “plan,” “contemplate,” “anticipate,” “believe,” “intend,” “continue,” expect,” “project,” “predict,” “estimate,” “could,” “should,” “would,” “will,” “goal,” “target” and similar expressions. These 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: inability to obtain governmental approvals of the Merger on the proposed terms and schedule and the assignment of certain Citizens South FDIC loss-share agreements; failure of Park Sterling’s or Citizens South’s shareholders to approve the Merger; fluctuation in the trading price of Park Sterling’s common stock prior to the closing of the Merger, which would affect the total value of the proposed merger transaction; legal and regulatory developments that adversely affect the businesses in which Park Sterling or Citizens South are engaged; changes in accounting standards, rules and interpretations, inaccurate estimates or assumptions in accounting, and the impact on Park Sterling’s or Citizens South’s financial statements. These forward-looking statements are not guarantees of future results or performance and involve certain risks and uncertainties that are based on management’s beliefs and assumptions and on the information available to Park Sterling or Citizens South at the time that these disclosures were prepared. Actual outcomes and results may differ materially from those expressed in, or implied by, any of these forward-looking statements.

You should not place undue reliance on any forward-looking statement and should consider all of the following uncertainties and risks, as well as those more fully discussed in any of Park Sterling’s or Citizens South’s filings with the SEC. Forward-looking statements speak only as of the date they are made, and Park Sterling and Citizens South undertake no obligation to update any forward-looking statement to reflect the impact of circumstances or events that arise after the date the forward-looking statement was made.
