Due Diligence Review

          The Company acknowledges and agrees that KBW’s obligation to perform the services contemplated by this Engagement Agreement shall be subject to the satisfactory completion of such investigations and inquiries relating to the Company, and its directors, officers, agents and employees, as KBW and KBW’s counsel in their sole discretion my deem appropriate under the circumstances. The Company agrees it will make available to KBW all relevant information, whether or not publicly available, which KBW reasonably requests, and will permit KBW to discuss with the Board of Directors and senior management the operations and prospects of the Company. KBW will treat all material non-public information as confidential. The Company recognizes and confirms that KBW (a) will use and rely on such information in performing the services contemplated by this Engagement Agreement without having independently verified the same, and (b) does not assume responsibility for the accuracy or completeness of the information or to conduct any independent verification or any appraisal or physical inspection of properties or assets. KBW will assume that all financial forecasts have been reasonably prepared and reflect the best then currently available estimates and judgments of the Company’s senior management as to the expected future financial performance of the Company.

3.

Regulatory Filings

          The Company will cause appropriate Offering documents to be filed with all regulatory agencies including the Securities and Exchange Commission (“SEC”), the Financial Industry Regulatory Authority (“FINRA”, formerly the NASD), and the appropriate federal and/or state bank regulatory agencies. In addition, the Company and KBW agree that the Company’s counsel shall serve as counsel with respect to blue sky matters in connection with the Offering, and that the Company shall cause such counsel to prepare a Blue Sky Memorandum related to the Offering including KBW’s participation therein and shall furnish KBW a copy thereof addressed to KBW or upon which counsel shall state KBW may rely.

4.

Fees

For the services hereunder, the Company shall pay the following fees to KBW at closing unless stated otherwise:

(a)

Management Fee: A Management Fee of $50,000 payable in four consecutive monthly installments of $12,500 commencing with the first month following the execution of this Engagement Agreement. Such fees shall be deemed to have been earned when due.

			Should the Offering be terminated for any reason not attributable to the action or inaction of KBW, KBW shall have earned and be entitled to be paid fees accruing through the stage at which point the termination occurred.
	(b)		Success Fee: A Success Fee of 1.25% shall be paid based on the aggregate Purchase Price (the “Purchase Price”) of Common Stock sold in the Subscription and Community Offering excluding shares purchased by the Company’s officers, directors, or employees (or members of their immediate family) plus any ESOP, tax-qualified or stock based compensation plans (except IRA’s) or similar plan created by the Company for some or all of their directors or employees, or any charitable foundation established by the Company (or any shares contributed to such a foundation). The Management Fee described in 5(a) will be credited against any Success Fee paid pursuant to this paragraph.
	(c)		Syndicated Community Offering: If any shares of the Company’s stock remain available after the Subscription Offering and Community Offering, at the request of the Company, KBW will seek to form a syndicate of registered broker-dealers to assist in the sale of such common stock on a best efforts basis, subject to the terms and conditions set forth in a selected dealers agreement to be entered into between the Company and KBW. KBW will endeavor to distribute the common stock among dealers in a fashion that best meets the distribution objectives of the Company and the Plan. KBW will be paid a fee not to exceed 5.5% of the aggregate Purchase Price of the shares of common stock sold in the Syndicated Community Offering. From this fee, KBW will pass onto selected broker-dealers, who assist in the Syndicated Community Offering, an amount competitive with gross underwriting discounts charged at such time for comparable amounts of stock sold at a comparable price per share in a similar market environment. Fees with respect to purchases effected with the assistance of a broker/dealer other than KBW shall be transmitted by KBW to such broker/dealer. (The decision to utilize selected broker-dealers will be made by the Company after consultation with KBW.)

5.

Expenses

          The Company will bear those expenses of the proposed Offering customarily borne by issuers, including, without limitation, regulatory filing fees, SEC, “Blue Sky,” and FINRA filing and registration fees; the fees of the Company’s accountants, attorneys, appraiser, transfer agent and registrar, printing, mailing and marketing and syndicate expenses associated with the Offering; the fees set forth in Section 5; and fees for “Blue Sky” legal work.

          If KBW incurs expenses on behalf of Company, the Company will reimburse KBW for such expenses. KBW shall be reimbursed for its reasonable out-of-pocket expenses related to the Offerings, including costs of coach class air travel, meals and lodging, photocopying, telephone, facsimile, and couriers. KBW will be reimbursed for fees and expenses of its counsel not to exceed $60,000. These expenses assume no unusual circumstances or delays, or a re-solicitation in connection with the Offerings.
