RECITALS

A.           Pursuant to the terms of the Agreement and Plan of Merger dated as of the date hereof, by and between the Buyer and the Company (as the same may be amended or supplemented, the “Merger Agreement”), the Company will merge with and into the Buyer, with the Buyer continuing as the surviving entity (the “Merger”).

B.           As an inducement for the Buyer to enter into the Merger Agreement, the Buyer has required that each Shareholder enter into this Agreement.

AGREEMENT

In consideration of the Buyer’s and the Company’s performance under the Merger Agreement, each Shareholder agrees as follows:

1.            Definitions. Capitalized terms not defined in this Agreement have the meaning assigned to those terms in the Merger Agreement.

2.            Effectiveness. If the Merger Agreement is terminated for any reason in accordance with its terms, this Agreement shall automatically terminate and be null and void and of no effect.

3.            Voting Agreement. From the date hereof until the earlier of (i) the Effective Time or (ii) the termination of the Merger Agreement in accordance with its terms (the “Support Period”), Shareholder irrevocably and unconditionally hereby agrees that at any shareholder meeting of the Company to approve the Merger Agreement and the transactions contemplated thereby or any adjournment or postponement thereof, Shareholder shall be present (in person or by proxy) and shall vote (or cause to be voted) the voting shares of capital stock of the Company beneficially owned (as defined in Rule 13d–3 promulgated under the Securities and Exchange Act of 1934, as amended) by such Shareholder as of the date hereof along with all such shares over which the Shareholder may acquire beneficial ownership from time to time after the date hereof, in each case that are entitled to vote at such Company shareholder meeting (together, “Owned Shares”): (a) in favor of (1) approval of the Merger Agreement and the transactions contemplated thereby and (2) approval of any proposal to adjourn or postpone such meeting to a later date if there are not sufficient votes to approve the Merger Agreement; and (b) against (1) any action or agreement that would result in the inability of the Buyer to complete the Merger, the inability of the Company to complete the Merger, or that would otherwise be inconsistent with, prevent, impede or delay the consummation of the transactions contemplated by the Merger Agreement and (2) other than the transactions contemplated by the Merger Agreement, any proposal that relates to an Acquisition Proposal without regard to the terms of such proposal. Shareholder represents and warrants and covenants and agrees that, except for this Agreement, he or she (x) has not entered into, and shall not enter into during the Support Period, any voting agreement or voting trust with respect to the Owned Shares and (y) has not granted, and shall not grant during the Support Period, a proxy, consent or power of attorney with respect to the Owned Shares except any proxy to carry out the intent of this Agreement. Shareholder hereby acknowledges that Shareholder is, in his or her capacity as a shareholder of the Company, bound by the restrictions set forth in Section 6.5 of the Merger Agreement and agrees consistent therewith not to solicit or facilitate any Acquisition Proposal.

4.            Grant of Irrevocable Proxy; Appointment of Proxy. During the Support Period, each Shareholder hereby irrevocably and unconditionally grants to, and appoints, the Buyer and any designee thereof as such Shareholder’s proxy and attorney-in-fact (with full power of substitution), for and in the name, place and stead of such Shareholder, to vote or cause to be voted (including by proxy or written consent, if applicable) the Owned Shares owned by such Shareholder as of the applicable record date in accordance with Section 3 of this Agreement; provided that each Shareholder grant of the proxy contemplated by this Section 4 shall be effective if, and only if, such Shareholder has not delivered to the Company prior to the meeting at which any of the matters described in Section 4 are to be considered, a duly executed irrevocable proxy card directing that the Owned Shares of such Shareholder be voted in accordance with Section 3 of this Agreement; provided, further, that any grant of such proxy shall only entitle the Buyer or its designee to vote on the matters specified by Section 3, and each Shareholder shall retain the authority to vote on all other matters. Each Shareholder hereby affirms that the irrevocable proxy set forth in this Section 4, if it becomes effective, is given in connection with the execution of the Merger Agreement, and that such irrevocable proxy is given to secure the performance of the duties of such Shareholder under this Agreement. The parties hereby further affirm that the irrevocable proxy, if it becomes effective, is coupled with an interest and is intended to be irrevocable until the end of the Support Period, at which time it will terminate automatically. If for any reason any proxy granted herein is not irrevocable after it becomes effective, then the Shareholder granting such proxy agrees, until the end of the Support Period, to vote the Owned Shares in accordance with Section 3 of this Agreement. The parties agree that the foregoing is a voting agreement.

5.            Transfer Restrictions Prior to Merger. The Shareholder will not, during the Support Period, sell, transfer, assign, tender in any tender or exchange offer, pledge, encumber, hypothecate or otherwise dispose of (by merger, by testamentary disposition, by operation of law or otherwise), either voluntarily or involuntarily, enter into any swap or other arrangements that transfers to another, in whole or in part, any of the economic consequences of ownership of, enter into any contract, option or other arrangement or understanding with respect to the sale, transfer, assignment, pledge, lien, hypothecation or other disposition of (by merger, by testamentary disposition, by operation of law or otherwise) or otherwise convey or dispose of, any of the Owned Shares, or any interest therein, including the right to vote any Owned Shares, as applicable (a “Transfer”); provided that Shareholder may Transfer Owned Shares for estate planning purposes or to a charitable institution for philanthropic purposes so long as the transferee, prior to the date of Transfer, agrees in a signed writing to be bound by and comply with the provisions of this Agreement.

Nothing in this Agreement, express or implied, is intended to or shall confer upon any other person any right, benefit or remedy of any nature whatsoever under or by reason of this Agreement.

10.          Remedies/Specific Enforcement. Each of the parties hereto agrees that this Agreement is intended to be legally binding and specifically enforceable pursuant to its terms and that each of the Buyer and the Company would be irreparably harmed if any of the provisions of this Agreement are not performed in accordance with their specific terms and that monetary damages would not provide adequate remedy in such event. Accordingly, in the event of any breach or threatened breach by Shareholder of any covenant or obligation contained in this Agreement, in addition to any other remedy to which the Buyer or the Company may be entitled (including monetary damages), each of the Buyer and the Company shall be entitled to injunctive relief to prevent breaches of this Agreement and to specifically enforce the terms and provisions hereof. Shareholder further agrees that none of the Buyer, the Company or any other person or entity shall be required to obtain, furnish or post any bond or similar instrument in connection with or as a condition to obtaining any remedy referred to in this paragraph, and Shareholder irrevocably waives any right it may have to require the obtaining, furnishing or posting of any such bond or similar instrument.

Venue of any legal action or proceeding between the parties related to this Agreement shall be in any federal or state court located in the State of Ohio, and the parties each consent to the personal jurisdiction of the courts of the State of Ohio and the federal courts located in the State of Ohio. Each Shareholder agrees not to claim that the State of Ohio is an inconvenient place for trial.

12.          Individual Obligations. The obligations of each of the Shareholders under this Agreement are several and not joint. This Agreement is binding on each Shareholder that executes this Agreement regardless of whether any other Shareholder(s) also executed this Agreement.

13.          Amendments; Waivers. Any provision of this Agreement may be amended or waived if, and only if, such amendment or waiver is in writing and signed (i) in the case of an amendment, by the Buyer, the Company and the Shareholder, and (ii) in the case of a waiver, by the party against whom the waiver is to be effective. No failure or delay by any party in exercising any right, power or privilege hereunder operate as a waiver thereof, nor shall any single or partial exercise thereof preclude any other or further exercise thereof or the exercise of any other right, power or privilege.
