WHEREAS, the Company and the Purchaser mutually desire to further amend the Amended Original Agreement, as set
forth in this Amendment; 
 NOW, THEREFORE, in consideration of the premises, representations, warranties
and the mutual covenants contained in this Amendment, the Parties agree as follows: 
 1. Article IV,
Section 4.05 of the Amended Original Agreement is hereby deleted in its entirety and the following new Section 4.05 is inserted in place thereof: 
 Section 4.05 Regulatory Filings. As soon as practicable following the date of this Agreement, but in no event later than February 29, 2012, (a) the Purchaser shall
prepare and file with the Federal Reserve and the ODFI a notice pursuant to the Change in Bank Control Act of 1978, as amended (the “CBCA”) and Ohio Rev.Code § 1115.06, respectively, including entering into and submitting such
appropriate passivity and anti-association commitments as the Federal Reserve may require to obtain confirmation from the Federal Reserve and the ODFI to the effect that the purchase of the Common Stock will not result in the Purchaser being deemed
in control of the Company for purposes of the Bank Holding Company Act of 1956, as amended, and (b) Company shall request approval from the Federal Reserve, FDIC and the ODFI of the Business Plan referenced in Section 6.01(d). Each Party
shall cooperate in the preparation and, where appropriate, filing of their respective notices or applications with all Regulatory Authorities having jurisdiction over the transactions contemplated by the Transaction Documents, seeking the








 
requisite Consents necessary to consummate the transactions contemplated by the Transaction Documents. The Company or the Purchaser, as applicable, shall permit the other Party to review those
portions of such notices or applications containing information pertaining to such Party for a reasonable time prior to filing the same. To the extent available, the Parties shall request expedited treatment of such applications, and shall use each
of their commercially reasonable efforts to pursue approval of the notices or applications. Neither Party’s obligations under this Section 4.05 shall be construed as including an obligation to accept any terms of or conditions to a
Consent, authorization, order, or approval of, or any exemption by, any Regulatory Authority or other Party that are not acceptable to that respective Party, in its sole reasonable discretion, or to change the business practices of that respective
Party in a manner not acceptable to that respective Party, in its sole reasonable discretion. In advance of filing any notices or applications for such regulatory approvals, each Party shall provide the other Party and its counsel with a copy of
such applications (including the Revised Business Plan contemplated by Section 6.01(d) hereof), and provide the other Party a reasonable opportunity to comment thereon with respect to any portion thereof containing information pertaining to
such Party, and thereafter shall promptly advise the other Party and its counsel of any material communication received by the filing Party or its counsel from any Regulatory Authorities with respect to such notices or applications. 

2. Article VIII, Section 8.01(d) of the Amended Original Agreement is hereby deleted in its entirety and the
following new Subsection 8.01(d) is inserted in place thereof: 
 (d) by written notice by the Company or the
Purchaser, as the case may be, in the event the Closing has not occurred on or prior to July 31, 2012 for any reason other than delay or nonperformance of or breach by the Party seeking such termination. 

3. Except as expressly amended hereby, the terms and provisions of the Amended Agreement remain in full force and effect
in all respects, and are expressly incorporated by reference in this Amendment. In the event of a conflict between the terms of this Amendment and the Amended Original Agreement, the terms of this Amendment will prevail. 

4. A facsimile or electronic copy of any counterpart of this Amendment with a signature of a Party hereto shall be given
the same legal effect as the original. 
 5. This Amendment may be executed in one or more counterparts, each of
which will be deemed an original but all of which together will constitute one and the same instrument. 







 IN WITNESS WHEREOF, the Company and the Purchaser have executed this
Amendment as of the day and year first above written.
