The Company will no longer be offering 300,000 primary shares of its common stock as part of the Offering, and will likewise no longer be granting the underwriters a 30-day option to purchase up to an additional 330,000 shares of its common stock to cover over-allotments, if any. As revised, the Offering will consist of a total of 1,900,000 shares, with BankAtlantic Bancorp, Inc. offering 1,600,000 shares and the Western and Southern Life Insurance Company offering 300,000 shares of the Company’s common stock.

The Company will not receive any proceeds from the sale of shares of its common stock by BankAtlantic Bancorp, Inc. or Western and Southern Life Insurance Company in the Offering. As previously announced, the Offering will be made pursuant to an effective shelf registration statement previously filed with the Securities and Exchange Commission.
