RECITALS

WHEREAS, as of the date hereof, the Shareholders beneficially own an aggregate of 3,700,000 shares of common stock, no par value, and 48,095 shares of the Series A Convertible Preferred Stock, no par value (such shares, or any other voting or equity securities of the Company hereafter acquired by any Shareholder prior to the termination of this Agreement, being referred to herein collectively as the “Shares”);

WHEREAS, concurrently with the execution of this Agreement, Purchaser and the Company are entering into an Agreement and Plan of Share Exchange, dated as of the date hereof (the “Share Exchange Agreement”), pursuant to which the Purchaser has agreed to acquire all of the outstanding shares of the Company (the “Transaction”) on the terms and subject to the conditions set forth therein; and

WHEREAS, as a condition to the willingness of the Company to enter into the Share Exchange Agreement, the Company has required that the Shareholders agree, and in order to induce the Company to enter into the Share Exchange Agreement the Shareholders are willing, to enter into this Agreement.

NOW, THEREFORE, in consideration of the foregoing and the mutual covenants and agreements contained herein, and intending to be legally bound hereby, the parties hereby agree, severally and not jointly, as follows:

Section 1. Voting of Shares.

Each Shareholder covenants and agrees that until the termination of this Agreement in accordance with the terms hereof, at the Company’s special meeting of shareholders or any other meeting of the shareholders of the Company, however called, and in any action by written consent of the shareholders of the Company, such Shareholder will vote, or cause to be voted, all of such Shareholder’s respective Shares owned at the record date for such meeting or consent (i) in favor of the adoption of the Share Exchange Agreement and the approval of the Transaction contemplated by the Share Exchange Agreement and any actions required in furtherance thereof, as the Share Exchange Agreement may be modified or amended from time to time and (ii) in favor of approval of the Alternative Acquisition Agreement pursuant to Section 11-030 of the Kentucky Business Corporation Act, provided that the Company shall have complied with Section 7.2 of the Share Exchange Agreement and paid the applicable

Break-Up Fee to the Purchaser.  For purposes hereof, (a) a “Qualifying Acquisition” means the acquisition of all of the Company’s outstanding shares of capital stock for cash, including the acquisition of all shares of Series A Convertible Preferred Stock for a cash price no less than the greater of (x) the price payable in such transaction for the shares of Common Stock into which such Series A Convertible Preferred Stock is then convertible and (y) the then liquidation preference of the Series A Convertible Preferred Stock and (b) the “Alternative Acquisition Agreement” is the definitive agreement with respect to a Qualifying Acquisition that, if the Share Exchange Agreement had not previously been terminated pursuant to Section 9.1(d)(ii) of the Share Exchange Agreement, the Company enters into in accordance with Section 7.2(e) of the Share Exchange Agreement.  This Agreement does not relate to any non voting securities of the Company, or to derivatives, swaps or other arrangements with respect to shares of capital stock of the Company where the Shareholder has no right to vote or direct the vote of such shares.

Section 2. Transfer of Shares.  Each Shareholder covenants and agrees that, except for (x) tenders of Shares pursuant to a tender offer (pursuant to the Alternative Acquisition Agreement or otherwise) and (y) sales of Shares following termination of the Share Exchange Agreement pursuant to Rule 144 under the Securities Act of 1933, such Shareholder will not directly or indirectly (i) sell, assign, transfer, tender, pledge, encumber or otherwise dispose of any of the Shares, (ii) deposit any of the Shares into a voting trust or enter into a voting agreement or arrangement with respect to the Shares or grant any proxy or power of attorney with respect thereto that is inconsistent with this Agreement or (iii) enter into any contract, option or other arrangement or undertaking with respect to the direct or indirect sale, assignment, transfer, tender, pledge, encumbrance, or other disposition of any Shares; provided, however, that notwithstanding the foregoing a Shareholder may transfer Shares or agree to transfer Shares to any Affiliate of the Shareholder, including, but not limited to Purchaser, provided that in each such case the transferee agrees in writing to be bound by this Agreement. Nothing herein shall restrict or otherwise limit the encumbrance or pledge of Shares pursuant to margin and/or other pledge arrangements, provided that in the event of any new margin or pledge arrangement, the voting rights of such Shares shall be subject to Section 1 hereof.

Section 3. Waiver of Appraisal Rights. Each Shareholder hereby waives, to the full extent of the law, and agrees not to assert any appraisal rights pursuant to Subtitle 13 of the Kentucky Business Corporation Act or otherwise in connection with the Transaction with respect to any and all Shares held by the undersigned of record or beneficially owned.

Section 4. Representations and Warranties of the Shareholders. Each Shareholder on his or its own behalf hereby severally represents and warrants to the Company with respect to such Shareholder and such Shareholder’s ownership of the Shares as follows:

(a) Number of Shares. Each Shareholder represents, warrants and agrees that Schedule I annexed hereto sets forth, adjacent to the name of such Shareholder, the number of Shares of which the Shareholder is the beneficial owner (it being understood and agreed that the beneficial ownership shall not include any rights with respect to derivatives, swaps or other arrangements). Each Shareholder represents, warrants and agrees that, as of the date hereof, those Shares on Schedule I constitute all of the Shares of which such Shareholder has the power to vote or direct the vote.

Section 5. Representations and Warranties of the Company. The Company represents and warrants to the Shareholders as follows:

Power, Binding Agreement. The Company is a corporation duly incorporated, validly existing and in good standing under the laws of the Commonwealth of Kentucky and has full corporate power and authority to execute and deliver this Agreement and to consummate the transactions contemplated hereby.
