As of the date hereof, the Bancorp Financial board of directors has no knowledge of any business that will be presented for consideration at the Bancorp Financial special meeting and that would be required to be set forth in this proxy statement/prospectus or the related proxy card other than the matters set forth in Bancorp Financial’s Notice of Special Meeting of Stockholders. If any other matter is properly presented at the Bancorp Financial special meeting for consideration, the persons named in the enclosed form of proxy and acting thereunder will vote in accordance with their discretion on such matter.

If you hold shares of Bancorp Financial common stock through a bank, broker or other nominee, you are considered the “beneficial holder” of the shares held for you in what is known as “street name.” The holder of record of such shares is your bank, broker or other nominee, and not you, and you must provide your bank, broker or other nominee with instructions on how to vote your shares.
