Whenever used in this Agreement, the following words and phrases shall have the meanings specified:

1.1 “Account Value” means the amount shown on Schedule A, under the heading Account Value. The parties expressly acknowledge that the Account Value at any given time may be different from the liability that should be then accrued by the Bank, under Generally Accepted Accounting Principles (“GAAP”), for the Bank’s obligation to the Executive under Section 2.1 of this Agreement. The Account Value on any date other than the end of a Plan Year shall be determined by adding the prorated increase, calculated on a per diem basis and a 365-day year, attributable to the current Plan Year to the Account Value as of the end of the previous Plan Year.

1.2 “Base Salary” means the annual cash compensation relating to services performed during any calendar year, excluding distributions from nonqualified deferred compensation plans, bonuses, commissions, overtime, fringe benefits, stock options, relocation expenses, incentive payments, non-monetary awards, and other fees, and automobile and other allowances paid to the Executive for services rendered (whether or not such allowances are included in the Executive’s gross income). Base Salary shall be calculated before reduction for compensation voluntarily deferred or contributed by the Executive pursuant to all qualified or non-qualified plans of the Bank and shall be calculated to include amounts not otherwise included in the Executive’s gross income under Code Sections 125, 402(e)(3), 402(h), or 403(b) pursuant to plans established by the Bank; provided, however, that all such amounts will be included in compensation only to the extent that had there been no such plan, the amount would have been payable in cash to the Executive.

1.8 “Code” means the Internal Revenue Code of 1986, as amended, and all regulations and guidance thereunder, including such regulations and guidance as may be promulgated after the Effective Date of this Agreement.

1.9 “Date of Hire” means the day, month and year the Executive began service to the Bank.

1.10 “Disability” means the Executive: (i) is unable to engage in any substantial gainful activity by reason of any medically determinable physical or mental impairment which can be expected to result in death or can be expected to last for a continuous period of not less than twelve (12) months; or (ii) is, by reason of any medically determinable physical or mental impairment which can be expected to result in death or can be expected to last for a continuous period of not less than twelve (12) months, receiving income replacement benefits for a period of not less than three (3) months under an accident and health plan covering employees of the Bank. Medical determination of Disability may be made by either the Social Security Administration or by the provider of an accident or health plan covering employees or directors of the Bank provided that the definition of “disability” applied under such insurance program complies with the requirements of the preceding sentence. Upon the request of the Plan Administrator, the Executive must submit proof to the Plan Administrator of the Social Security Administration’s or the provider’s determination.

1.11 “Early Termination” means Separation from Service before Normal Retirement Age for reasons other than death, Disability, Termination for Cause or Good Reason.

-2-

Final Average Compensation shall be based on the number of full calendar years in which the Executive was an employee of the Bank (again counting the final year of employment as an annualized full calendar year).

names someone other than the Executive’s spouse as a Beneficiary, the Plan Administrator may, in its sole discretion, determine that spousal consent is required to be provided in a form designated by the Plan Administrator, executed by the Executive’s spouse and returned to the Plan Administrator. The Executive’s beneficiary designation shall be deemed automatically revoked if the Beneficiary predeceases the Executive or if the Executive names a spouse as Beneficiary and the marriage is subsequently dissolved.

The Plan Administrator may require proof of incompetence, minority or guardianship as it may deem appropriate prior to distribution of the benefit. Any distribution of a benefit shall be a distribution for the account of the Executive and the Beneficiary, as the case may be, and shall be completely discharge of any liability under the Agreement for such distribution amount.

Article 5

General Limitations

5.1 Termination for Cause. Notwithstanding any provision of this Agreement to the contrary, the Bank shall not distribute any benefit under this Agreement if Executive’s service is terminated by the Bank for any of the following reasons (a “Termination for Cause”):

(a) The willful and continued failure by the Executive to substantially perform his or her duties with the Bank (other than any such failure resulting from the Executive’s incapacity due to physical or mental illness or any such actual or anticipated failure resulting from the Executive’s termination for Good Reason), after a written demand for substantial performance is delivered to the Executive by the Bank which specifically identifies the manner in which the Bank believes that the Executive has not substantially performed his or her duties; or

-7-

(b) The willful engaging by the Executive in misconduct which is demonstrably and materially injurious to the Bank, monetarily or otherwise.

For purposes of this Subsection, no act or failure to act on the Executive’s part shall be considered “willful” whether done at the direction of the Board, or otherwise unless done, or omitted to be done, by the Executive not in good faith and without reasonable belief that his or her action or omission was in the best interest of the Bank. Notwithstanding the foregoing, the Executive shall not be deemed to have been terminated for Cause unless and until there shall have been delivered to the Executive a copy of a resolution duly adopted by the affirmative vote of not less than three-quarters (3/4) of the entire membership of the Board at a meeting of the Board called and held for the purpose (after reasonable notice to the Executive and an opportunity for the Executive, together with his or her counsel, to be heard before the Board) finding that in the good faith opinion of the Board, the Executive was guilty of conduct set forth above in clauses (a) or (b) not timely cured by the Executive and specifying the particulars thereof in detail.

5.2 Removal. Notwithstanding any provision of this Agreement to the contrary, the Bank shall not be legally obligated to distribute any benefit under this Agreement if at the time such distribution is due, the Executive is subject to a final removal or prohibition order issued by an appropriate federal banking agency pursuant to Section 8(e) of the Federal Deposit Insurance Act.

5.3 Non-compete Provision. The Executive shall forfeit any non-distributed benefits under this Agreement if during the term of this Agreement and within twenty-four (24) months following a Separation from Service, the Executive, directly or indirectly, either as an individual or as a proprietor, stockholder, partner, officer, director, employee, agent, consultant or independent contractor of any individual, partnership, corporation or other entity (excluding an ownership interest of three percent (3%) or less in the stock of a publicly-traded company), without the prior written consent of the Bank:

(a) becomes employed by, participates in, or becomes connected in any manner with the ownership, management, operation or control of any bank, savings and loan or other similar financial institution if the Executive’s responsibilities will include providing banking or other financial services within twenty-five (25) miles of any office (sites solely with an ATM not being deemed to be an office for this purpose) maintained by the Bank as of the date of the termination of the Executive’s employment;

(b) participates in any way in hiring or otherwise engaging, or assisting any other person or entity in hiring or otherwise engaging, on a temporary, part-time or permanent basis, any individual who was employed by the Bank as of the date of termination of the Executive’s employment;

(e) divulges, discloses, or communicates to others in any manner whatsoever, any confidential information of the Bank, including, but not limited to, the names and addresses of customers or prospective customers, of the Bank, as they may have existed from time to time, of work performed or services rendered for any customer, any method and/or procedures relating to projects or other work developed for the Bank, earnings or other information concerning the Bank. The restrictions contained in this subparagraph (e) apply to all confidential information regarding the Bank, regardless of the source who provided or compiled such information. Notwithstanding anything to the contrary, all confidential information referred to herein may be disclosed to the extent it becomes known to the general public from sources other than the Executive.

5.3.1 Judicial Remedies. In the event of a breach or threatened breach by the Executive of any provision of the restrictions set forth in this Section 5.3, the Executive recognizes the substantial and immediate harm that a breach or threatened breach will impose upon the Bank, and further recognizes that in such event monetary damages may be inadequate to fully protect the Bank. Accordingly, in the event of a breach or threatened breach of these restrictions, the Executive agrees that the Bank may obtain preliminary, interlocutory, temporary or permanent injunctive, or any other equitable relief, protecting and fully enforcing the Bank’s rights hereunder and preventing the Executive from further breaching any of his or her obligations set forth herein. Nothing herein shall be construed as prohibiting the Bank from pursuing any other remedies available to the Bank at law or in equity for such breach or threatened breach, including the recovery of damages from the Executive. The Executive expressly acknowledges and agrees that: (i) the restrictions set forth in Section 5.3 hereof are reasonable, in terms of scope, duration, geographic area, and otherwise, (ii) the protections afforded the Bank in this Section 5.3.I hereof are necessary to protect its legitimate business interest, (iii) the restrictions set forth in Section 5.3 hereof will not be materially adverse to the Executive’s employment with the Bank, and (iv) his or her agreement to observe such restrictions forms a material part of the consideration for this Agreement.

5.3.2 Overbreadth of Restrictive Covenant. It is the intention of the parties that if any restrictive covenant in this Agreement is determined by a court of competent jurisdiction to be overly broad, then the court should enforce such restrictive covenant to the maximum extent permitted under the law as to area, breadth and duration.

In the event it shall become impossible for the Bank or the Plan Administrator to perform any act required by this Agreement due to regulatory or other constraints, the Bank or Plan Administrator may perform such alternative act as most nearly carries out the intent and purpose of this Agreement, is in the best interests of the Bank and is consistent with the deferral of income under Code Section 409A.

9.14 Deduction Limitation on Benefit Payments. If the Bank reasonably anticipates that the Bank’s deduction with respect to any distribution under this Agreement would be limited or eliminated by application of Code Section 162(m), then to the extent deemed necessary by the Bank to ensure that the entire amount of any distribution from this Agreement is deductible, the Bank may delay payment of any amount that would otherwise be distributed under this Agreement. The delayed amounts shall be distributed to the Executive (or the Beneficiary in the event of the Executive’s death) at the earliest date the Bank reasonably anticipates that the deduction of the payment of the amount will not be limited or eliminated by application of Code Section 162(m).
