On May 22, 2011, CenterState Banks, Inc. (the “Company”) entered into an Agreement and Plan of Merger (“Agreement”) with The Hartford Financial Services Group, Inc. (“Hartford”), and Federal Trust Corporation (“FTC”), a wholly owned subsidiary of Hartford, whereby FTC will be merged with and into the Company. Pursuant to and simultaneously with entering into the Agreement, the Company’s wholly owned subsidiary bank, CenterState Bank of Florida, N.A. (“CenterState”) and FTC’s wholly owned subsidiary bank, Federal Trust Bank (“FTB”) have entered into a Plan of Merger and Merger Agreement (“Bank Merger Agreement”) whereby FTB will be merged with and into CenterState simultaneously with the merger of FTC with and into the Company.

Pursuant to the terms of the Agreement, FTC will sell, assign and transfer to Hartford, or Hartford’s designee, all if its assets and liabilities except for the following which will be acquired by the Company:

FTC will cause FTB to sell, assign or transfer to Hartford, or Hartford’s designee, all of FTB’s assets and liabilities except for the following which will be acquired by CenterState:

The Company will assume the TruPs for par value, and will not pay a premium or receive a discount. The dividend payment is equal to LIBOR plus 2.95% adjustable quarterly. The maturity date is September 17, 2033.

CenterState will assume all of FTB’s deposits without payment of a premium or receipt of a discount. Leased branch property will be assumed by CenterState and all branch properties purchased by CenterState will be for current market value based on appraisals. The related furniture, fixtures and equipment, along with certain other miscellaneous assets and liabilities will be purchase, or assumed in the case of liabilities, for book value at the Effective Time.

CenterState will purchase the selected performing loans for 73% of their legal unpaid balance as of the Effective Time. In addition, pursuant to the terms of the Agreement, for a period of one year subsequent to the Effective Time, CenterState has the option to put back any purchased loan that becomes 30 days past due or becomes adversely classified by applicable regulatory standards for loan classification established by the OCC.

The transaction is expected to close before year end and is subject to a number of conditions, including the receipt of regulatory approval. The Company expects to recognize a pre-tax bargain purchase gain sufficient enough to self-capitalize the transaction and not require the use of any of the Company’s current excess capital. The transaction will be immediately accretive to tangible book value, and expected to be dilutive to 2012 earnings and accretive to 2013 earnings.
