     A. WHEREAS, the Stockholder is, as of the date hereof, the beneficial holder of 15,642,858 shares of common stock of Liberator Medical Holdings, Inc., a Nevada corporation (the “Company”), par value $.001 per shares (the “Common Stock”), which constitutes 45.97% of the Company’s outstanding Common Stock;

     B. WHEREAS, Kinderhook is purchasing an aggregate of 4,666,667 shares (the “Kinderhook Shares”) of Common Stock of the Company pursuant to that certain Securities Purchase Agreement between Kinderhook and the Company, dated the date hereof (the “SPA”);

     C. WHEREAS, in connection with the consummation of the transactions contemplated by the SPA, the Stockholder has agreed to provide for the future voting of his shares of the Company’s Common Stock as set forth below.

     NOW THEREFORE, in consideration of Kinderhook entering into the SPA and the mutual promises and covenants set forth herein, the parties hereto agree as follows:

1.     Kinderhook Director.

     1.1 Upon the request of Kinderhook at any time during the term of this Agreement, the Stockholder agrees to vote or to cause to be voted all of the Shares (as defined below) now owned or hereafter acquired by such Stockholder or any of its affiliates or which such Stockholder or any of its affiliates may be empowered to vote from time to time and at all times in whatever manner as shall be reasonably necessary (including, without limitation, voting to amend the Company’s Certificate of Incorporation, if necessary, to increase the number of directors) to ensure that a director selected at Kinderhook’s sole discretion and request be elected to the Company’s board of directors (the “Kinderhook Director”). Such Kinderhook Director shall be an additional director to be added as a member of the board of directors as such board is then currently constituted. It is understood and agreed that the initial Kinderhook Director may be Morgan Duke.

     1.2 Removal. The Stockholder shall not vote to remove the Kinderhook Director, other than for Cause (as defined below). “Cause” shall mean (i) the Kinderhook Director’s conviction of, or plea of nolo contendere, to a felony or crime involving moral turpitude, (ii) if it is finally judicially determined by a court of competent jurisdiction that the Kinderhook Director has violated his fiduciary duties to the Company in any material respect, or (iii) if the person serving as the Kinderhook Director would cause the Company to be in violation of any law or regulation material to the Company. In any such situation, Kinderhook will be entitled to select another person to be elected or appointed to the Company’s Board of Directors in accordance with the terms of this Agreement and the SPA.

     1.3 Shares. “Shares” shall mean and include any and all shares of Common Stock, Preferred Stock and any other shares of capital stock of the Company, by whatever name called, which carry voting rights (including without limitation voting rights which arise by reason of default) and shall include any such shares now owned or subsequently acquired by the Stockholder, however acquired, including without limitation stock splits and stock dividends.

     1.4 Vacancy. The Stockholder agrees to vote all of his Shares from time to time and at all times in whatever manner as shall be reasonably necessary to ensure that in the event that a Kinderhook Director, for any reason, shall cease to serve as a member of the Board of Directors during his or her term in office, the resulting vacancy on the Board of Directors shall be filled in accordance with this Agreement.

     1.5 Further Action. The Stockholder agrees to take such further actions as shall be reasonably necessary to carry out the intent of this Agreement, including, but not limited to, calling a special meeting of stockholders or initiating or signing and delivering an action by written consent of the stockholders for the purpose of adding, electing or removing a director as contemplated hereby. The Stockholder shall vote all of his Shares entitled to vote at such meeting or in connection with such consent in accordance with this Agreement.

2.     Specific Enforcement. The parties acknowledge and agree that the parties hereto would be irreparably damaged in the event any of the provisions of this Agreement were not performed by the parties in accordance with their specific terms or were otherwise breached. Accordingly, it is agreed that the Stockholder and Kinderhook shall be entitled to an injunction to prevent breaches of this Agreement and to specifically enforce this Agreement and the terms and provisions hereof in any action instituted in any court of the United States or any state thereof having subject matter jurisdiction, in addition to any other remedy to which the parties may be entitled at law or in equity.

3.     Grant of Proxy. Should the provisions of this Agreement be construed to constitute the granting of proxies, such proxies shall be deemed coupled with an interest and are irrevocable for the term of this Agreement.
