WHEREAS, Meridian wishes to assure itself of the services of Kraeutler for the period hereinafter provided, and Kraeutler is willing to be employed by Meridian for such period, upon the terms and conditions provided in this Agreement.

NOW, THEREFORE, in consideration of the premises and mutual covenants contained herein and for other good and valuable consideration, the receipt of which is mutually acknowledged, Meridian and Kraeutler agree as follows:

1. Employment. Meridian hereby employs Kraeutler, and Kraeutler shall serve Meridian, on the terms and conditions set forth herein.

2. Term. Subject to the provisions for earlier termination as hereinafter provided, Kraeutler shall be employed for thirty-six months commencing on the date hereof (the “Initial Term”). The Agreement shall have a three year evergreen term. Accordingly, the Agreement shall automatically be extended daily for an additional one day period until a date thirty-six months after either party gives the other written notice of its intent to stop the automatic daily extension. The Initial Term together with any extensions shall hereinafter be referred to as the “Term.”

3. Position and Duties; Place of Performance.

3.1 Kraeutler shall serve as Chief Executive Officer of Meridian and shall perform all duties customarily attendant to that position and shall include those duties reasonably assigned to Kraeutler from time-to-time by the Board of Directors of Meridian.

3.2 Kraeutler shall devote substantially all of his working time and effort to Meridian and shall not, without Meridian’s prior written consent, furnish like or similar services to anyone else or engage directly or indirectly in any activity adverse to Meridian’s interests. Kraeutler will promote and develop business opportunities relating to Meridian’s current and anticipated future business that come to his attention in a manner consistent with Kraeutler’s duties and Meridian’s best interests.

3.3 In connection with Kraeutler’s employment by Meridian, Kraeutler will be based at the principal place of business of Meridian in Cincinnati, Ohio.

4. Compensation.

4.1 Base Salary. During the Term of Kraeutler’s employment with Meridian, as compensation for Kraeutler’s services under this Agreement, Meridian agrees to pay to Kraeutler an annual base salary (the “Base Salary”) of Five Hundred Twenty-Five Thousand Dollars ($525,000). Meridian’s Board of Directors shall in good faith review the Base Salary annually, taking into account changes in Kraeutler’s responsibilities, increases in the cost of living, performance of Kraeutler, increases in salaries to other executives of Meridian and other pertinent factors, and may, in its reasonable discretion, increase the Base Salary. Any increase in the Base Salary shall not serve to limit or reduce any other obligation to Kraeutler under this Agreement. The Base Salary shall not be reduced without the express written consent of Kraeutler. The term Base Salary as used in this Agreement shall refer to the Base Salary as so increased.

4.2 Annual Bonus. Kraeutler shall be eligible to receive an annual bonus as established by the Board of Directors in addition to Base Salary.

4.3 Other Compensation. In addition to compensation specified in this Agreement, Kraeutler shall be eligible to receive stock options and other compensation under Meridian’s compensation plans and arrangements available from time to time to Meridian’s officers. Meridian stock options, restricted stock and other incentive compensation subject to vesting (Award), granted to Kraeutler shall vest according to the agreement entered into with Kraeutler at the time of the grant of such Award; provided, however, that the Award shall fully vest upon the happening of any of the following events: Change of Control Event (as defined in Section 8.7) or termination of Kraeutler’s employment without Cause (as defined in Section 7.3), due to death or Disability (as defined in Section 7.2) or Kraeutler’s termination of employment for Good Reason (as defined in Section 7.4).

5. Expense Reimbursement. Kraeutler shall be entitled to prompt reimbursement by Meridian for all reasonable out-of-pocket expenses incurred by him in performing services under this Agreement, upon submission of such accounts and records as may be required under Meridian policy.

6. Other Benefits.

6.1 Benefit Plans and Programs. Kraeutler shall be entitled, at Meridian’s expense, to such medical, dental, hospitalization, life insurance, pension plan, profit-sharing, employee benefits and such other similar employment privileges and benefits or perquisites as are afforded generally from time to time to other senior officers of Meridian.

During the Term of Kraeutler’s employment with Meridian, Kraeutler shall be entitled to paid vacation time in accordance with the plans, practices, policies, and programs applicable to other senior officers of Meridian, but in no event shall such vacation time be less than four weeks per year.

7. Termination of Employment. Notwithstanding the provisions of Section 2, Kraeutler’s employment may be terminated under the following circumstances:

7.1 Death. Kraeutler’s employment is terminated upon his death.

7.2 Disability. Kraeutler’s employment may be terminated by Meridian due to illness or other physical or mental disability of Kraeutler, resulting in his inability to perform substantially his duties under this Agreement for a period of Ninety or more consecutive days or for One Hundred Eighty days in the aggregate during any consecutive Twelve month period (“Disability”).

7.3 Cause. Kraeutler’s employment may be terminated by Meridian upon Notice of Termination to Kraeutler of action taken by the Board of Directors of Meridian to discharge Kraeutler for Cause, which Notice of Termination shall be delivered to Kraeutler within Ninety days after the Board of Directors has both (x) knowledge of the conduct or event allegedly constituting Cause and (y) reason to believe that such conduct or event constitutes grounds to terminate Kraeutler for Cause. As used herein, “Notice of Termination” means a resolution duly adopted by the affirmative vote of not less than a simple majority of the members of the Board of Directors of Meridian, excluding Kraeutler, at a meeting called for the purpose of determining that Kraeutler engaged in conduct that constitutes Cause (and at which Kraeutler had a reasonable opportunity, together with his counsel, to be heard before the Board of Directors prior to such vote). For purposes of this Agreement, Meridian shall have “Cause” to terminate Kraeutler’s employment upon:

(i) an intentional act of fraud, embezzlement or theft in the course of Kraeutler’s employment with Meridian resulting in material harm to Meridian; or

(ii) intentional wrongful damage to material assets of Meridian.

Any act or omission by Kraeutler shall be deemed “intentional” only if done, or omitted to be done, by Kraeutler not in good faith and without the reasonable belief that his action or omission was in or not opposed to the best interests of Meridian. Failure to meet performance standards or objectives set by Meridian shall not constitute “Cause” for purposes of this Agreement.

7.4 Good Reason. Kraeutler’s employment may be terminated by Kraeutler for Good Reason. For purposes of this Agreement, “Good Reason” shall mean (i) the assignment to Kraeutler of any duties materially inconsistent with Kraeutler’s position (including, without limitation, status, offices, titles and reporting requirements), authority, duties or responsibilities as contemplated by this Agreement, or any other action by Meridian that results in a material diminution in such position, authority, duties or responsibilities, excluding for this purpose an action not taken in bad faith and that is remedied by Meridian within Ten days after receipt of written notice thereof given by Kraeutler, provided that repeated instances of such action shall constitute the bad faith of Meridian; (ii) a 5% or more reduction in Kraeutler’s Base Salary or other benefits under this Agreement; (iii) the relocation of Meridian’s principal offices to a location more than Fifty miles from the current location of such offices; (iv) any material failure by Meridian to comply with any of the provisions of this Agreement, other than a failure not occurring in bad faith and which is remedied by Meridian within Ten days after receipt of written notice thereof given by Kraeutler, provided that repeated failures shall constitute the bad faith of Meridian; or (v) removal of Kraeutler as Chief Executive Officer, other than for Cause.

8. Compensation Upon Termination.

8.1 If Kraeutler’s employment is terminated voluntarily without Good Reason, terminated as a result of Kraeutler’s death, or is terminated by Meridian for Cause, Kraeutler, or his estate, shall be entitled to:

(i) any Base Salary earned but not yet paid;

(ii) any bonus awarded pursuant to Section 4.2 of this Agreement but not yet paid;

(iii) upon Kraeutler’s death, all or a portion of the Performance Bonus that he would have received pursuant to Section 4.2 (assuming that Kraeutler and/or Meridian achieves the goals necessary to receive any level of bonus potential for that year) for the year in which the termination occurred (pro rata, according to the number of days Kraeutler was employed by Meridian during such year) payable in a lump sum.

(iv) reimbursement in accordance with this Agreement of any reasonable business expense incurred by Kraeutler but not yet paid; and

(v) other benefits accrued and earned by Kraeutler through the date of his death or termination in accordance with applicable plans and programs of Meridian.

8.2 If Kraeutler’s employment is terminated as a result of Kraeutler’s Disability, Kraeutler shall be entitled to receive on an annual basis until Kraeutler reaches age sixty-five the full amount of Kraeutler’s Base Salary plus Performance Bonus and group health and life insurance benefits until Kraeutler reaches age 65 at the same level that Kraeutler was receiving such benefits at the date of termination. Compensation paid shall be prorated during periods of less than one year. The amount of annual Base Salary plus Performance Bonus shall be computed by averaging the Base Salary plus Performance Bonus earned by Kraeutler during the preceding three fiscal years of Meridian.

8.3 If (a) Kraeutler’s employment is terminated by Meridian without Cause, (b) Kraeutler terminates his employment with Meridian for Good Reason or (c) Kraeutler’s employment is terminated for any reason (with or without Cause or voluntary or involuntary) upon or within ninety days of a Change of Control Event (as defined below), Kraeutler shall be entitled to:

(i) (A) any Base Salary earned but not yet paid, plus (B) three times his Base Salary (computed as the average annual Base Salary of Kraeutler for the preceding thirty-six months).

(ii) any bonuses awarded pursuant to Section 4.2 of this Agreement but not yet paid and three times the average annual Performance Bonus received by Kraeutler for the preceding thirty-six months.

(iii) continued participation in all employee benefit plans and/or programs at Meridian’s expense in which he was participating on the date of his termination of employment for a period equal to the lesser of three years and the date that Kraeutler is employed at another location.

(iv) reimbursement in accordance with this Agreement of any business expenses incurred by Kraeutler but not yet paid to him on the date of his termination of employment.

(v) engagement, for a three month period, by Meridian on Kraeutler’s behalf of a recognized job recruitment agency for the purpose of locating subsequent employment for Kraeutler in a position of equal rank to Kraeutler’s position with Meridian.

8.4 Unless otherwise indicated, any payments payable under this Section 8 shall be paid in a lump sum payment as soon as practical after Kraeutler’s termination of employment but in any event no later than thirty days thereafter.

8.5 If, under the terms of any employee benefit plan referred to in subsection 8.3(iii) above, Kraeutler may not continue his participation, he shall be provided with the after-tax economic equivalent of the benefits provided under any plan in which he was previously eligible to participate for the period specified in subsection 8.3(iii) above. The economic equivalent of any benefit foregone shall be deemed to be the cost that would be incurred by Kraeutler in obtaining such benefit.

8.6 Any amounts due under this Section 8 are in the nature of severance payments or liquidated damages, or both, and shall fully compensate Kraeutler and his dependents or beneficiaries, as the case may be, for any and all direct damages and consequential damages that any of them may suffer as a result of termination of Kraeutler’s employment in breach of this Agreement, and they are not in the nature of a penalty.

Upon termination of Kraeutler’s employment for any reason other than by Meridian for Cause or by Kraeutler for Good Reason, Kraeutler and Meridian will, at the option of Kraeutler, execute and deliver to each other a general release releasing the other and in the case of Meridian its officers, directors, employees, agents, trustees, parents, subsidiaries, predecessors, and affiliates (the “Releasees”) from all causes of action, claims, or demands that either party may then have or have had against the Releasees based on any matter or thing, including but not limited to Kraeutler’s employment with Meridian or the termination of his employment (but not the obligations under this Agreement that continue after the date on which Kraeutler’s employment terminates). The execution of this release shall be a condition to the receipt by Kraeutler of the payments and benefits described in this Section 8 except that the execution of this release shall not be a condition for the receipt by Kraeutler of base salary earned but not yet paid, bonuses awarded pursuant to Section 4.2 of this Agreement but not yet paid and reimbursement of any business expenses incurred by Kraeutler but not yet paid.
