(a) General.

The following subsections (I), (II) and (III) of this Section 4(a) shall govern the obligations of the EMPLOYERS to the EMPLOYEE upon the occurrence of the events described in such subsections:

(I) Termination for JUST CAUSE. In the event that the EMPLOYERS terminate the employment of the EMPLOYEE during the TERM because of the EMPLOYEE’s personal dishonesty, willful misconduct, breach of fiduciary duty involving personal profit, intentional failure or refusal to perform the duties and responsibilities assigned in this AGREEMENT, willful violation of any law, rule, regulation or final cease-and-desist order (other than traffic violations or similar offenses), conviction of a felony or for fraud or embezzlement, or material breach of any provision of this AGREEMENT (collectively, “JUST CAUSE”), the EMPLOYEE shall not receive, and shall have no right to receive, any compensation or other benefits for any period after such termination. No act, or failure to act, on the EMPLOYEE’s part shall be considered “willful” unless he has acted or failed to act with an absence of good faith and without a reasonable belief that his action or failure to act was in the best interests of the EMPLOYERS.

(II) Termination in connection with CHANGE OF CONTROL. In the event that the EMPLOYERS terminate the employment of the EMPLOYEE before the expiration of the TERM without JUST CAUSE and within six months before a CHANGE OF CONTROL (as defined hereinafter) or within one year after a CHANGE OF CONTROL, then the following shall occur:

(A) The EMPLOYERS shall promptly pay to the EMPLOYEE or to his dependents, beneficiaries or estate an amount equal to three times the EMPLOYEE’S COMPENSATION (as defined below) in a lump sum without reduction for time value of money or other discount. “EMPLOYEE’S COMPENSATION” shall mean the higher of base salary at the time of the CHANGE OF CONTROL or at the termination of the EMPLOYEE’s employment, plus the highest bonus paid to the EMPLOYEE by the EMPLOYERS during the five years preceding his termination or such shorter period of time as the EMPLOYEE has been employed by the EMPLOYERS;

(B) The EMPLOYEE, his dependents, beneficiaries and estate shall be covered under either the health, life and disability plans of the EMPLOYERS or the health, life and disability plans of the successors, survivors or assigns of the EMPLOYERS, without any material diminution in coverage or benefit at the expense of the EMPLOYERS or the successors, survivors or assigns of the EMPLOYERS as if the EMPLOYEE were still employed under this AGREEMENT until the earliest of the expiration of the termination of the EMPLOYEE’s employment, 24 months after termination of the EMPLOYEE’s employment, or the date on which the EMPLOYEE is included in another employer’s benefit plans as a full-time employee; provided, however, that if the EMPLOYERS choose or their successors choose, the EMPLOYERS or their successors may, instead of providing such health, life and disability benefits, pay the EMPLOYEE cash in an amount that, after payment of applicable federal, state and local income, employment and wage taxes, the EMPLOYEE will have sufficient cash to purchase equivalent coverage until the earlier of the expiration of the TERM or 24 months after the termination of the EMPLOYEE’s employment;

(C) The EMPLOYEE shall not be required to mitigate the amount of any payment provided for in this AGREEMENT by seeking other employment or otherwise, nor shall any amounts received from other employment or otherwise by the EMPLOYEE offset in any manner the obligations of the EMPLOYERS hereunder, except as specifically stated in subsection (B).

Provided, however, that in the event that the payments pursuant to this subsection (II), alone or in combination with any other compensation, would result in the imposition of a penalty tax pursuant to Section 280G(b)(3) of the Internal Revenue Code of 1986, as amended, and the regulations promulgated thereunder (collectively, “SECTION 280G”), such payments shall be reduced to the maximum amount that may be paid under SECTION 280G without exceeding such limits. Payments pursuant to this subsection II also may not exceed applicable limits established by the Office of the Comptroller of the Currency (the “OCC”), the Federal Deposit Insurance Corporation (the “FDIC”) or the Board of Governors of the Federal Reserve (the “FED”). In the event a reduction in payments is necessary in order to comply with the requirements of this AGREEMENT relating to the limitations of SECTION 280G or applicable regulatory limits, the EMPLOYEE may determine, in his sole discretion, which categories of payments are to be reduced or eliminated.

(A) In the event that the employment of the EMPLOYEE is terminated by the EMPLOYERS before the end of the TERM, for any reason other than death, JUST CAUSE or in connection with or within six months before or one year after a CHANGE IN CONTROL, or in the event that the employment of the EMPLOYEE is terminated by the EMPLOYEE under the circumstances set forth in the first paragraph of this Section 4(a), the EMPLOYERS shall be obligated (i) to make a lump sum payment to the EMPLOYEE within two weeks after the EMPLOYEE’s termination of employment in the amount equal to the EMPLOYEE’s annual salary provided pursuant to Section 3(a) or (b) of this AGREEMENT; and (ii) until the earlier of the eighteen-month anniversary of the termination of the EMPLOYEE’s employment or the EMPLOYEE’s becoming employed full-time by another employer, to provide to the EMPLOYEE, his dependents, beneficiaries and estate at the EMPLOYERS’ expense, health, life, disability and other benefits substantially equal to those being provided to the EMPLOYEE at the date of termination of his employment; provided, however, that if the EMPLOYERS choose or their successors choose, the EMPLOYERS or their successors may, instead of providing such health, life and disability benefits, pay the EMPLOYEE cash in an amount that, after payment of applicable federal, state and local income, employment and wage taxes, the EMPLOYEE will have sufficient cash to purchase equivalent coverage until the earlier of the expiration of the TERM or 18 months after the termination of the EMPLOYEE’s employment. The EMPLOYEE shall not be required to mitigate the amount of any payment provided for in this subsection (III)(A) by seeking other employment or otherwise, nor shall any amounts received from other employment or otherwise by the EMPLOYEE offset in any manner the obligations of the EMPLOYERS hereunder, except as specifically stated in this subsection (III)(A).

(B) In the event that the payments pursuant to this subsection (III), alone or in combination with any other compensation, would result in the imposition of a penalty tax pursuant to SECTION 280G, such payments shall be reduced to the maximum amount which may be paid under SECTION 280G without exceeding such limits. Payments pursuant to this subsection (III) also may not exceed applicable limits established by the OCC, the FDIC or the FED. In the event a reduction in payments is necessary in order to comply with the requirements of this AGREEMENT relating to SECTION 280G or applicable regulatory limits, the EMPLOYEE may determine, in his sole discretion, which categories of payments are to be reduced or limited.

(b) Death of the EMPLOYEE. The TERM automatically terminates upon the death of the EMPLOYEE, unless the employment of EMPLOYEE has been terminated prior to the EMPLOYEE’s death pursuant to Section 4(a) of this AGREEMENT. In the event of such death, the EMPLOYEE’s estate shall be entitled to receive the compensation due the EMPLOYEE through the last day of the calendar month in which the death occurred, except as otherwise specified herein.

(c) “Golden Parachute” Provision. Any payments made to the EMPLOYEE pursuant to this AGREEMENT, or otherwise, are subject to and conditioned upon their compliance with 12 U.S.C. §1828(k) and Federal Deposit Insurance Corporation (“FDIC”) regulation 12 C.F.R. Part 359, Golden Parachute and Indemnification Payments.

(d) Definition of “CHANGE OF CONTROL”. A “CHANGE OF CONTROL” shall mean any one of the following events: (i) the acquisition, directly or indirectly, of ownership or power to vote more than 50% of the voting stock of either of the EMPLOYERS; (ii) the merger of either of the EMPLOYERS into, or the consolidation of either of the EMPLOYERS with, another corporation, or the merger of another corporation into either of the EMPLOYERS, on a basis whereby less than fifty percent of the total voting power of the surviving corporation is represented by shares held by former shareholders of HOLDING COMPANY prior to such merger or consolidation; (iii) the acquisition of the ability to control the election of a majority of the directors of either of the EMPLOYERS; (iv) during any period of two consecutive years, individuals who at the beginning of such period constitute the Board of Directors of HOLDING COMPANY or BANK cease for any reason to constitute at least a majority thereof; provided, however, that any individual whose election or nomination for election as a member of the Board of Directors of HOLDING COMPANY or BANK was approved by a vote of at least two-thirds of the directors then in office shall be considered to have continued to be a member of the Board of Directors of HOLDING COMPANY or BANK; (v) the acquisition by any person or entity of the power to direct either of BANK’s management or policies, if the Board of Directors has made a determination that such acquisition constitutes or will constitute an acquisition of control of either of the EMPLOYERS for the purpose of the Bank Holding Company Act or the Change in Bank Control Act and the regulations thereunder; or (vi) BANK shall have sold substantially all of its assets. For purposes of this paragraph, the term “person” refers to an individual or corporation, partnership, trust, association, joint venture, pool, syndicate or other organization or entity.

Notwithstanding the foregoing, in no event shall the ownership of stock of BANK by HOLDING COMPANY or the ownership of stock of HOLDING COMPANY by an employee benefit plan sponsored or maintained by BANK or HOLDING COMPANY constitute a CHANGE OF CONTROL.

Section 5. Special Regulatory Events. Notwithstanding Section 4 of this AGREEMENT, the obligations of the EMPLOYERS to the EMPLOYEE shall be as follows in the event of the following circumstances:

(a) If the EMPLOYEE is suspended and/or temporarily prohibited from participating in the conduct of the EMPLOYERS’ affairs by a notice served under Section 8(e) (3) or (g) (1) of the Federal Deposit Insurance Act (the “FDIA”), the EMPLOYERS’ obligations under this AGREEMENT shall be suspended as of the date of service of such notice, unless stayed by appropriate proceedings. If the charges in the notice are dismissed, the EMPLOYERS may, in their discretion, pay the EMPLOYEE all or part of the compensation withheld while the obligations in this AGREEMENT were suspended and reinstate, in whole or in part, any of the obligations that were suspended.

(b) If the EMPLOYEE is removed and/or permanently prohibited from participating in the conduct of the EMPLOYERS’ affairs by an order issued under Section 8(e) (4) or (g) (l) of the FDIA, all obligations of the EMPLOYERS under this AGREEMENT shall terminate as of the effective date of such order; provided, however, that vested rights of the EMPLOYEE shall not be affected by such termination.

Section 6. Consolidation, Merger or Sale of Assets. Nothing in this AGREEMENT shall preclude the EMPLOYERS from consolidating with, merging into, or transferring all, or substantially all, of their assets to another corporation that assumes all of the EMPLOYERS’ obligations and undertakings hereunder. Upon such a consolidation, merger or transfer of assets, the term “EMPLOYERS” as used herein shall mean such other corporation or entity and this AGREEMENT shall continue in full force and effect; provided, however, that the assumption of the EMPLOYERS’ obligations and undertakings hereunder shall not affect the EMPLOYEE’s right to payments pursuant to Section 4(a) (II) of this AGREEMENT in connection with such consolidation, merger or transfer of assets.

Section 7. Confidential Information. The EMPLOYEE acknowledges that during his employment he will learn and have access to confidential information regarding the EMPLOYERS and their customers and businesses. The EMPLOYEE agrees and covenants not to disclose or use for his own benefit, or the benefit of any other person or entity, any confidential information, unless or until the EMPLOYERS’ consent to such disclosure or use or such information becomes common knowledge in the industry or is otherwise legally in the public domain. The EMPLOYEE shall not knowingly disclose or reveal to any unauthorized person any confidential information relating to the EMPLOYERS, their subsidiaries or affiliates, or to any of the businesses operated by them, and the EMPLOYEE confirms that such information constitutes the exclusive property of the EMPLOYERS. The EMPLOYEE shall not otherwise knowingly act or conduct himself (a) to the material detriment of the EMPLOYERS, their subsidiaries, or affiliates, or (b) in a manner which is inimical or contrary to the interests of the EMPLOYERS.

Section 8. Nonassignability. Neither this AGREEMENT nor any right or interest hereunder shall be assignable by the EMPLOYEE, his beneficiaries, or legal representatives without the EMPLOYERS’ prior written consent; provided, however, that nothing in this Section 8 shall preclude (a) the EMPLOYEE from designating a beneficiary to receive any benefits payable hereunder upon his death, or (b) the executors, administrators, or other legal representatives of the EMPLOYEE or his estate from assigning any rights hereunder to the person or persons entitled thereto.

Section 9. No Attachment. Except as required by law, no right to receive payment under this AGREEMENT shall be subject to anticipation, commutation, alienation, sale, assignment, encumbrance, charge, pledge or hypothecation or to execution, attachment, levy, or similar process of assignment by operation of law, and any attempt, voluntary or involuntary, to effect any such action shall be null, void and of no effect.

Section 10. Binding AGREEMENT. This AGREEMENT shall be binding upon, and inure to the benefit of, the EMPLOYEE and the EMPLOYERS and their respective permitted successors and assigns.

Section 11. Arbitration and Legal Expenses. Any dispute or controversy arising under or in this AGREEMENT shall be settled exclusively by arbitration in accordance wit the rules of the American Arbitration Company then in effect. Judgment may be entered on the arbitrator’s award in any court having jurisdiction. The EMPLOYERS shall promptly pay all legal fees and expenses (including the costs of experts, evidence and counsel) that the EMPLOYEE may incur as a result of the EMPLOYEE or the EMPLOYER contesting the validity or enforceability of this AGREEMENT or the EMPLOYEE seeking to obtain any right or benefit provided by this AGREEMENT if an arbitrator or a court of competent jurisdiction renders a final decision in favor of the EMPLOYEE with respect to any such contest, or to the extent agreed upon by the EMPLOYERS and the EMPLOYEE in an agreement of settlement with respect to any such contest.

Section 12. Amendment of AGREEMENT. This AGREEMENT may not be modified or amended, except (a) by an instrument in writing signed by the parties hereto or (b) by the EMPLOYERS, without any additional consideration to the EMPLOYEE, to the extent deemed necessary by the EMPLOYERS upon the advice of legal counsel to avoid penalties arising under Section 409A of the Internal Revenue Code of 1986, as amended, and regulations thereunder, even if those amendments reduce, restrict or eliminate rights granted under this AGREEMENT.

Section 13. Waiver. No term or condition of this AGREEMENT shall be deemed to have been waived, nor shall there be an estoppel against the enforcement of any provision of this AGREEMENT, except by written instrument of the party charged with such waiver or estoppel. No such written waiver shall be deemed a continuing waiver, unless specifically stated therein, and each waiver shall operate only as to the specific term or condition waived and shall not constitute a waiver of such term or condition for the future or as to any act other than the act specifically waived.

Section 14. Severability. If, for any reason, any provision of this AGREEMENT is held invalid, such invalidity shall not affect the other provisions of this AGREEMENT not held so invalid, and each such other provision shall, to the full extent consistent with applicable law, continue in full force and effect. If this AGREEMENT is held invalid or cannot be enforced, then any prior AGREEMENT between the EMPLOYERS (or any predecessor thereof) and the EMPLOYEE shall be deemed reinstated to the full extent permitted by law, as if this AGREEMENT had not been executed.

Section 15. Headings. The headings of the paragraphs herein are included solely for convenience of reference and shall not control the meaning or interpretation of any of the provisions of this AGREEMENT.

Section 16. Governing Law. This AGREEMENT has been executed and delivered in the State of Ohio and its validity, interpretation, performance, and enforcement shall be governed by the laws of this State of Ohio, except to the extent that federal law is governing.

Section 17. Effect of Prior Agreements. This AGREEMENT contains the entire understanding between the parties hereto and supersedes any prior employment agreement between the EMPLOYERS and the EMPLOYEE, each of which is hereby terminated and is of no further force or effect.

IN WITNESS WHEREOF, the EMPLOYERS have caused this AGREEMENT to be executed by their duly authorized officers, and the EMPLOYEE has signed this AGREEMENT, each as of the day and year first above written.

This AGREEMENT is made to be effective as of , 2006, by and between NB&T Financial Group, Inc. (the “COMPANY”), and John J. Limbert (the “OPTIONEE”).

WHEREAS, the Board of Directors of the COMPANY has determined to retain the services of the OPTIONEE as the President and Chief Executive Officer of the COMPANY and its subsidiary, The National Bank and Trust Company (the “BANK”);

WHEREAS, as a material inducement to the OPTIONEE’s entering into employment with the COMPANY and the BANK and to more closely align the OPTIONEE’s interests with those of the shareholders of the COMPANY, the COMPANY wishes to award an option to purchase shares of the COMPANY to the OPTIONEE; and

WHEREAS, the Board of Directors of the COMPANY has determined to award to the OPTIONEE an option to purchase 30,000 common shares of the COMPANY, no par value per share, of the COMPANY (the “COMMON SHARES”);

NOW, THEREFORE, in consideration of the above premises and intending to be legally bound by this AGREEMENT, the parties hereto agree to the following:

1. Grant of Option. The COMPANY hereby grants to the OPTIONEE an option to purchase 30,000 COMMON SHARES (the “OPTION”). The OPTION is not intended to qualify as an incentive stock option under Section 422 of the Internal Revenue Code of 1986, as amended (the “CODE”). The COMMON SHARES to be issued upon the exercise of the OPTION may be either authorized and unissued shares or issued shares that have been reacquired by the COMPANY. No fractional shares shall be issued pursuant to this AGREEMENT.

(A) OPTION Price. The purchase price (the “OPTION PRICE”) to be paid by the OPTIONEE to the COMPANY upon the exercise of the OPTION shall be $ per share, being 100% of the fair market value of a COMMON SHARE on , 2006, as determined by the mean between the bid and the asked price of a COMMON SHARE on the NASDAQ Capital Market at the close of trading on this date.

(B) Exercise of the OPTION. Subject to the other provisions of this AGREEMENT, the OPTION is exercisable in accordance with the following schedule:

The OPTION shall remain exercisable until the date of expiration of the OPTION term. In the event that the employment of the OPTIONEE terminates for any reason except death, then within 90 days next succeeding such termination, but not later than 10 years from the date of grant of the option, the OPTIONEE may exercise such option rights as he then has under this AGREEMENT. To the extent the OPTION awarded pursuant to this AGREEMENT has not been exercised during such 90 days, the OPTION shall thereupon expire and shall not be exercisable thereafter. In the event of the OPTIONEE’s death, the executor or administrator of his estate may exercise the OPTIONEE’s rights under this AGREEMENT at any time within 180 days next succeeding the OPTIONEE’s death, but not later than 10 years from the effective date of this AGREEMENT. To the extent the OPTION has not been exercised within the period set forth in the preceding sentence, the OPTION shall thereupon expire and shall not be exercisable thereafter.

The OPTION may be exercised to purchase less than the total number of COMMON SHARES subject to the OPTION and exercisable at any time and from time to time. The OPTION may not be exercised unless the COMMON SHARES issued upon such exercise are first registered pursuant to any applicable federal and state laws or regulations or, in the opinion of securities counsel to the COMPANY, are exempt from such registration. Nothing contained in this AGREEMENT shall be construed to require the COMPANY to take any action whatsoever to make the OPTION exercisable or to make transferable any shares issued upon the exercise of the OPTION.

(C) Change of Control. Subject to and except as otherwise provided in this AGREEMENT, upon the occurrence of a “CHANGE OF CONTROL,” the OPTION shall become fully exercisable. A “CHANGE OF CONTROL” shall mean any one of the following events occurring after the date of this AGREEMENT: (i) the acquisition, directly or indirectly, of ownership or power to vote more than 50% of the voting stock of either of the COMPANY or the BANK; (ii) the merger of either of the COMPANY or the BANK into, or the consolidation of either of the COMPANY or the BANK with, another corporation, or the merger of another corporation into either of the COMPANY or the BANK, on a basis whereby less than fifty percent of the total voting power of the surviving corporation is represented by shares held by former shareholders of the COMPANY prior to such merger or consolidation; (iii) the acquisition of the ability to control the election of a majority of the directors of either of the COMPANY or the BANK; (iv) during any period of two consecutive years, individuals who at the beginning of such period constitute the Board of Directors of the COMPANY or the BANK cease for any reason to constitute at least a majority thereof; provided, however, that any individual whose election or nomination for election as a member of the Board of Directors of the COMPANY or the BANK was approved by a vote of at least two-thirds of the directors then in office shall be considered to have continued to be a member of the Board of Directors of the COMPANY or the BANK; (v) the acquisition by any person or entity of the power to direct the BANK’s management or policies, if the Board of Directors has made a determination that such acquisition constitutes or will constitute an acquisition of control of either of the COMPANY or the BANK for the purpose of the Bank Holding Company Act or the Change in Bank Control Act and the regulations thereunder; or (vi) the BANK shall have sold substantially all of its assets. For purposes of this paragraph, the term “person” refers to an individual or corporation, partnership, trust, association, joint venture, pool, syndicate or other organization or entity.

(D) OPTION Term. Subject to the right of the COMPANY to provide for earlier termination in the event of any merger, acquisition or consolidation involving the COMPANY, the OPTION shall in no event be exercisable after the expiration of 10 years from the date of this AGREEMENT.

(E) Method of Exercise. The OPTION may be exercised by delivering written notice of exercise to the COMPANY in care of its Chief Financial Officer or its Chairman. The notice must state the number of shares subject to the OPTION in respect of which it is being exercised and must be accompanied by payment in full of the OPTION PRICE in cash, unless the Board of Directors of the COMPANY in its sole discretion permits payment of the OPTION PRICE in COMMON SHARES already owned by the OPTIONEE, by the surrender of outstanding awards of OPTIONS or by simultaneously exercising the OPTION and selling COMMON SHARES thereby acquired and using the proceeds from such sale as payment of the purchase price of such COMMON SHARES.

(F) Satisfaction of Taxes and Tax Withholding. The COMPANY or a subsidiary shall be entitled, if the Board of Directors deems it necessary or desirable, to withhold (or secure payment from the OPTIONEE in lieu of withholding) the amount necessary to satisfy any withholding or employment-related tax obligation attributable to the exercise of the OPTION or otherwise incurred with respect to the OPTION, and the COMPANY may defer delivery of any shares pursuant to the exercise of the OPTION unless indemnified to its satisfaction. The Board of Directors may, in its discretion and subject to such rules as the Board of Directors may adopt, permit the OPTIONEE to satisfy, in whole or in part, any withholding or employment-related tax obligation which may arise in connection with the grant, exercise or disposition of the OPTION by electing to have the COMPANY withhold COMMON SHARES to be issued, or by electing to deliver to the COMPANY COMMON SHARES already owned by the OPTIONEE having a fair market value (as determined by the mean between the bid and the asked prices of the COMMON SHARES on the NASDAQ Capital Market, if the COMMON SHARES are then traded on such market, or otherwise as determined by the Board of Directors if the COMMON SHARES are not traded on such market at that time) equal to the amount of such tax obligation.

3. Non-Assignability of the OPTION. Once granted, the OPTION shall not be assignable or transferable except by will or by the laws of descent and distribution, and the terms and conditions of the OPTION shall be binding upon each and every executor, administrator, heir, beneficiary or other successor to the OPTIONEE’s interest.

(a) The existence of this AGREEMENT and the OPTION shall not affect or restrict in any way the right or power of the Board of Directors of the COMPANY or the shareholders of the COMPANY to make or authorize the following: any adjustment, recapitalization, reorganization or other change in the COMPANY’s capital structure or its business; any merger, acquisition or consolidation of the COMPANY; any issuance of bonds, debentures, preferred or prior preference stocks ahead of or affecting the COMPANY’s capital stock or rights thereof; the dissolution or liquidation of the COMPANY or any sale or transfer of all or any part of its assets or business; or any other corporate act or proceeding, including any merger or acquisition which would result in the exchange of cash, stock of any other company or options to purchase the stock of another company for the OPTION or which would involve the termination of the OPTION at the time of such corporate transaction.

(b) In the event of any change in capitalization affecting the COMMON SHARES of the COMPANY, such as a stock dividend, stock split, recapitalization, merger, consolidation, spin-off, split-up, combination or exchange of shares or other form of reorganization, or any other change affecting the COMMON SHARES, such proportionate adjustments, if any, as the Board of Directors of the COMPANY in its discretion may deem appropriate to reflect such change shall be made with respect to the aggregate number of COMMON SHARES subject to the OPTION and the OPTION PRICE.
