Article 5

General Limitations

5.1 Termination for Cause. Notwithstanding any provision of this Agreement to the contrary, the Bank shall not pay any benefit under this Agreement if Executive’s Termination of Employment by the Bank is due to:

(a) conviction or a plea of nolo contendere by the Executive to a felony or to fraud, embezzlement or misappropriation of funds;

(b) the commission of a fraudulent act or omission, breach of trust or fiduciary duty, or insider abuse with regard to the Bank, that has had a material adverse effect on the Bank;

(c) material violation by the Executive of any applicable federal banking law or regulation that has had a material adverse effect on the Bank; or

(d) the willful failure by the Executive, without communication to the Board of Directors before such act, to adhere to the Bank’s written policies, which causes a material monetary injury or other material harm to the Bank;

Notwithstanding the foregoing, the Executive shall not be deemed to have been terminated by reason of violating Sections 5.1(b), (c), or (d) until Executive is notified in writing by the Bank (or its successor entity) of a determination of a violation of Sections 5.1(b), (c), or (d), specifying the particulars thereof in reasonably sufficient detail, and giving the Executive a reasonable opportunity (of not less than ten (10) days), together with his counsel, to explain to the Bank why

5

there has been no violation of Sections 5.1(b), (c), or (d), followed by a finding by the Bank (i) that in the good faith opinion of the Bank (or its successor entity) the Executive had committed an act described in Sections 5.1(b), (c), or (d) above, (ii) specifying the particulars thereof in detail, and (iii) determining that such violation has not been corrected, or is not capable of correction. Nothing herein shall limit the right of the Executive or his Beneficiary to contest the validity or propriety of any such determination.

5.2 Golden Parachute Payment. Notwithstanding any provision of this Agreement to the contrary, the Bank shall not be required to pay any benefit under this Agreement if, upon the advice of counsel, the Bank determines that the payment of such benefit would be prohibited by 12 C.F.R. Part 359 or any successor regulations regarding employee compensation promulgated by any regulatory agency having jurisdiction over the Bank or its affiliates or to the extent the benefit would be a non-deductible excess parachute payment under Section 280G and 4999 of the Code. To the extent possible, such benefit payment shall be proportionately reduced to allow payment within the fullest extent permissible under applicable law.

5.3 Payment Restriction During TARP Period. Notwithstanding anything in this Agreement to the contrary, payment of benefits under Sections 2.1 or 2.2 will not commence during the TARP Period, and will instead be delayed and will commence on the first day of the month following the month in which the Holding Company has repaid all TARP Proceeds.

5.4 Changes to Time and/or Form of Payment. Notwithstanding anything in this Agreement to the contrary, any changes to the timing and or form of payment of benefits under this Agreement are subject to and must comply with the requirements of Code section 409A and the regulations and guidance issued thereunder.

Amendments and Termination

7.1 Amendment With Consent. This Agreement may be amended by written agreement between the Bank and the Executive; provided, however, that no such amendment shall reduce a benefit to which the Executive is entitled, nor shall any amendment delay or accelerate the payment of a benefit provided under this Agreement except in accordance with requirements under Code section 409A and the regulations and guidance issued thereunder.

7.2 Suspension of Agreement. The Bank may, in its sole discretion and prior to commencement of benefits under this Agreement, suspend this Agreement and cease all future accruals thereunder as of the date the Agreement is suspended. In such event, and unless and until the Agreement is later reinstated, upon the Executive’s subsequent Termination of Employment for any reason other than in connection with a Change in Control or death, the Executive shall be entitled to the vested portion of the Accrual Balance, determined in accordance with Section 2.2.2 as of the date the Agreement is suspended under this Section 7.2, with such payment to be made in a single lump-sum payment within sixty (60) days following Termination of Employment.

8.1. Binding Effect. This Agreement shall bind the Executive and the Bank, and their beneficiaries, survivors, executors, administrators, and permitted transferees.

8.2. No Guarantee of Employment. This Agreement is not an employment policy or contract. It does not give the Executive the right to remain an employee of the Bank, nor does it interfere with the Bank’s right to discharge the Executive. It also does not require the Executive to remain an employee nor interfere with the Executive’s right to terminate employment at any time.

8.3. Non-Transferability. Benefits under this Agreement cannot be sold, transferred, assigned, pledged, attached or encumbered in any manner, except in accordance with Article 4 with respect to designation of Beneficiaries.

The benefits represent the mere promise by the Bank to pay such benefits. The rights to benefits are not subject in any manner to anticipation, alienation, sale, transfer, assignment, pledge, encumbrance by the Executive or attachment or garnishment by the Executive’s creditors. Any insurance on the Executive’s life is a general asset of the Bank to which the Executive and Beneficiary have no preferred or secured claim.

8.7. Severability. Without limitation of any other section contained herein, in case any one or more provisions contained in this Agreement shall for any reason be held to be invalid, illegal or unenforceable in any other respect, such invalidity, illegality or unenforceability shall not affect the other provisions of this Agreement. In the event any one or more of the provisions found in the Agreement shall be held to be invalid, illegal or unenforceable by any governmental regulatory agency or court of competent jurisdiction, this Agreement shall be construed as if such invalid, illegal or unenforceable provision had never been a part of this Agreement and such provision shall be deemed substituted by such other provisions as will most nearly accomplish the intent of the parties to the extent permitted by applicable law.
