Clerical assistance and/or temporary staff will be billed separately. KBW will also be reimbursed for fees and expenses of its counsel not to exceed $120,000 (subject to the provisions of this paragraph). These expense caps assume no unusual circumstances or delays, and no resolicitation in connection with the Offerings.

Unless otherwise expressly stated in an opinion letter issued by KBW or otherwise expressly agreed, no one other than the Bank is authorized to rely upon this engagement of KBW or any statements or conduct by KBW. The Bank agrees that any such opinion or advice, as well as this Agreement (including any of the terms hereof) shall not be used, reproduced, disseminated, quoted or referred to at any time, in any manner, or for any purpose, nor shall any public references to KBW be made by the Bank or any of its representatives, without the prior written consent of KBW.

It is expressly understood and agreed that KBW is not undertaking to provide any advice relating to legal, regulatory, accounting or tax matters. In furtherance thereof, the Bank acknowledges and agrees that (a) it and its affiliates have relied and will continue to rely on the advice of its own legal, tax and accounting advisors for all matters relating to the Conversion and the Offerings, and all other matters and (b) neither it, or any of its affiliates, has received, or has relied upon, the advice of KBW or any of its affiliates regarding matters of law, regulation, taxation or accounting.

The Bank acknowledges and agrees that KBW has been retained to act solely as financial advisor to the Bank and not as an advisor to or agent of any other person, and the Bank’s engagement of KBW is not intended to confer rights upon any person not a party to this Agreement (including shareholders, employees or creditors of the Bank) as against KBW or its affiliates, or their respective directors, officers, employees or agents. In such capacity, KBW shall act as an independent contractor, and any duties arising out of its engagement shall be owed solely to the Bank. It is understood that KBW’s responsibility to the Bank is solely contractual in nature and KBW does not owe the Bank, or any other party, any fiduciary duty as a result of this Agreement.

The Bank agrees that, following the closing of the Offerings, KBW has the right to place advertisements in financial and other newspapers and journals at its own expense, describing its services to the Bank and a general description of such offering. In addition, the Bank agrees to include in any press release or public announcement announcing any such offering a reference to KBW’s role as financial advisor and sole bookrunning manager with respect to such offering, provided that the Bank will submit a copy of any such press release or public announcement to KBW for its prior approval, which approval shall not be unreasonably withheld or delayed.
