WHEREAS, concurrently with the execution and delivery of this Agreement, TKH, Ohio Merger Subsidiary, Inc., a Delaware corporation and a wholly-owned subsidiary of TKH (“Merger Subsidiary”), and the Company are entering into an Agreement and Plan of Merger, dated as of the date hereof (the “Merger Agreement”), whereby, among other things in accordance with the applicable provisions of the Delaware General Corporation Law, Merger Subsidiary will be merged with and into the Company, with the Company as the surviving corporation (the “Merger”) and as a result of the Merger, the Company will become a wholly-owned subsidiary of TKH; and

WHEREAS, as a condition to its willingness to enter into the Merger Agreement, TKH required that the Stockholder, and in order to induce TKH to enter into the Merger Agreement, the Stockholder (in the Stockholder’s capacity as a holder of the Subject Shares) has agreed to, enter into this Agreement.

NOW, THEREFORE, in consideration of the foregoing and the respective representations, warranties, covenants and agreements set forth below, and for other good and valuable consideration, the receipt and sufficiency of which are hereby acknowledged, and intending to be legally bound hereby, the parties hereto agree as follows:

ARTICLE 1
AGREEMENT TO VOTE

Section 1.01.         Voting of Subject Shares.  The Stockholder agrees that, until the date this Agreement is terminated in accordance with Section 4.03, at any meeting of the stockholders of the Company and at every adjournment or postponement thereof, the Stockholder shall, or shall cause the holder of record on any applicable record date to, vote (or cause to be voted) his or her Subject Shares:

(i)            in favor of the Merger Agreement and the transactions contemplated thereby, including the Merger;

(ii)           against the approval of any matter or proposal submitted to the stockholders of the Company for approval, if approval of such agreement would result in a breach in any material respect of any covenant, representation or warranty or any other obligation of the Company under the Merger Agreement; and

(iii)          against (A) any merger, rights offering, reorganization, recapitalization or liquidation involving the Company or any of its Subsidiaries (other than the Merger), (B) a sale or transfer of a material amount of assets or capital stock of the Company or any of its Subsidiaries or (C) any action that is intended, or could reasonably be expected, to materially impede, interfere with, delay, postpone or adversely affect the Merger and the other transactions contemplated by the Merger Agreement.

Section 1.02.         Irrevocable Proxies.  In order to secure the performance of the Stockholder’s obligations under this Agreement, by entering into this Agreement and solely with respect to the matters described in Section 1.01, the Stockholder hereby irrevocably grants a proxy appointing such Persons as TKH designates as the Stockholder’s attorney-in-fact and proxy, with full power of substitution, for and in his or her name, place and stead, to vote, express consent or dissent, or otherwise to utilize such voting power in the manner contemplated by and in accordance with Section 1.01, in such Person’s discretion, with respect to the Stockholder’s Subject Shares, in each case, until the termination of this Agreement in accordance with Section 4.03.  The Stockholder hereby affirms that the irrevocable proxy set forth in this Section 1.02 is given in connection with the execution of the Merger Agreement and affirms that such irrevocable proxy is coupled with an interest and may under no circumstances be revoked, except that such irrevocable proxy shall be revoked automatically, without any notice or other action by any Person, upon the termination of this Agreement in accordance with Section 4.03.  The Stockholder hereby ratifies and confirms all that such irrevocable proxy may lawfully do or cause to be done by virtue hereof.  THE PROXY AND POWER OF ATTORNEY SET FORTH IN THIS SECTION 1.02 IS IRREVOCABLE AND COUPLED WITH AN INTEREST.  The Stockholder shall execute and deliver to TKH any proxy cards that such Stockholder receives to vote in favor of the adoption of the Merger Agreement, the Merger or any of the transactions contemplated thereby.

Section 1.03.  Company Breach. For the avoidance of doubt, the Stockholder agrees that, during the term of this Agreement the obligations of the Stockholder specified in Section 1.01 shall not be affected by (i) any change in recommendation with respect to the Merger Agreement of the majority of the Board of Directors of the Company or (ii) any breach by the Company of any of its representations, warranties, agreements or covenants set forth in the Merger Agreement.

The Stockholder hereby represents and warrants as to itself, himself or herself, to TKH as follows:

Section 2.01.         Authorization; Binding Agreement.  The execution, delivery and performance by the Stockholder of this Agreement and the consummation of the transactions contemplated hereby are within its, his or her legal capacity and requisite powers, and if this Agreement is being executed in a representative or fiduciary capacity, the Person signing this Agreement has full power and authority to execute, deliver and perform this Agreement.  Assuming the due authorization, execution and delivery of this Agreement by TKH, this Agreement constitutes a legal, valid and binding agreement of the Stockholder enforceable against the Stockholder in accordance with its terms, except as such enforceability may be limited by bankruptcy, insolvency, reorganization, moratorium and other Laws of general applicability relating to or affecting creditors’ rights and by general principles of equity (regardless of whether such enforceability is considered in a proceeding in equity or at law).

Section 2.02.         Non-Contravention.  The execution and delivery of this Agreement by the Stockholder does not, and the performance of the terms of this Agreement by the Stockholder (or the attorney-in-fact and proxy’s voting of the Stockholder’s Subject Shares pursuant to the proxy contemplated by Section 1.02) will not (1) require the Stockholder to obtain the consent or approval of, or make any filing with or notification to, any Governmental Authority, (2) require the consent or approval of any other person pursuant to any agreement, obligation or instrument binding on the Stockholder or its properties and assets, (3) conflict with or violate any organizational document or Law applicable to the Stockholder’s Subject Shares or the Stockholder or pursuant to which the Stockholder is a party, including any voting agreement, stockholders agreement, irrevocable proxy or voting trust.  The Stockholder’s Subject Shares are not, with respect to the voting or transfer thereof, subject to any other agreement, including any voting agreement, stockholders agreement, irrevocable proxy or voting trust.

(ii)           grant any proxies or powers of attorney or enter into a voting agreement or other arrangement with respect to the Stockholder’s Subject Shares, other than this Agreement; nor

(iii)          enter into, or deposit the Stockholder’s Subject Shares into a voting trust or take any other action which would, or could reasonably be expected to, result in a diminution of the voting power represented by any of the Stockholder’s Subject Shares; nor

notice from the Company that such transfer is permitted under Section 3.01(i) of this Agreement, there is a stop transfer order with respect to all of the Stockholder’s Subject Shares.

Section 3.04.         Documentation and Information.  The Stockholder (i) consents to and authorizes the publication and disclosure by TKH and the Company and their affiliates of his or her identity and holding of Subject Shares and the nature of its, his or her commitments and obligations under this Agreement in any announcement or disclosure required by the SEC or other Governmental Authority, the Merger Agreement, or any other disclosure document in connection with the transactions contemplated by the Merger Agreement or this Agreement, and (ii) agrees promptly to give to TKH and the Company any information it may reasonably require for the preparation of any such disclosure documents; provided that, to the extent practicable, the Stockholder shall have a reasonable opportunity to review and comment on any such announcement or disclosure prior to its publication, filing or disclosure.  The Stockholder agrees to promptly notify TKH and the Company of any required corrections with respect to any written information supplied by it specifically for use in any such disclosure document, if and to the extent that any such information shall have become false or misleading in any material respect.
