AGREEMENT

NOW, THEREFORE, in consideration of the foregoing and for other good and valuable consideration, the receipt, sufficiency and adequacy of which are hereby acknowledged, the parties hereto agree as follows:

For purposes of this Agreement, capitalized terms used and not defined herein shall have the respective meanings ascribed to them in the Merger Agreement.

Each Stockholder represents and warrants to Parent with respect to himself, herself or itself, as applicable, as follows:

(a)     (i) Stockholder owns beneficially (as such term is defined in Rule 13d-3 under the Exchange Act) all of the Original Shares free and clear of all Encumbrances, and (ii) except pursuant hereto, there are no options, warrants or other rights, agreements, arrangements or commitments of any character to which Stockholder is a party relating to the pledge, disposition, or voting of any of the Original Shares and there are no voting trusts or voting agreements with respect to the Original Shares.

(b)     Stockholder does not beneficially own any shares of Company Common Stock other than (i) the Original Shares, (ii) Company Options, (iii) Company Warrants, and (iv) any other rights to acquire any additional shares of Company Common Stock or any security exercisable for or convertible into shares of Company Common Stock, set forth on the signature page of this Agreement.

(c)     Stockholder has full power and authority to enter into, execute and deliver this Agreement and to perform fully Stockholder's obligations hereunder (including the proxy described in Section 3(b) below)). This Agreement has been duly and validly executed and delivered by Stockholder and constitutes the legal, valid and binding obligation of Stockholder, enforceable against Stockholder in accordance with its terms.

(d)     None of the execution and delivery of this Agreement by Stockholder, the consummation by Stockholder of the transactions contemplated hereby or compliance by Stockholder with any of the provisions hereof will conflict with or result in a breach, or constitute a default (with or without notice of lapse of time or both) under any provision of, any trust agreement, loan or credit agreement, note, bond, mortgage, indenture, lease or other agreement, instrument or Legal Requirement applicable to Stockholder or to Stockholder's property or assets.

(e)     No consent, approval or authorization of, or designation, declaration or filing with, any Governmental Body or other Person on the part of Stockholder is required in connection with the valid execution and delivery of this Agreement. If Stockholder is an individual, no consent of Stockholder's spouse is necessary under any “community property” or other Legal Requirement in order for Stockholder to enter into and perform its obligations under this Agreement.

(a)     Each of the Stockholders agrees during the term of this Agreement to vote the Shares, and to cause any holder of record of Shares to vote or execute a written consent or consents if stockholders of the Company are requested to vote their shares through the execution of an action by written consent in lieu of any such annual or special meeting of stockholders of the Company: (i) in favor of the Merger and the Merger Agreement, at every meeting (or in connection with any action by written consent) of the stockholders of the Company at which such matters are considered and at every adjournment or postponement thereof; (ii) against (1) any Acquisition Proposal, (2) any action, proposal, transaction or agreement which could reasonably be expected to result in a breach of any covenant, representation or warranty or any other obligation or agreement of the Company under the Merger Agreement or of such Stockholder under this Agreement, and (3) any action, proposal, transaction or agreement that could reasonably be expected to impede, interfere with, delay, discourage, adversely affect or inhibit the timely consummation of the Merger or the fulfillment of Parent's, the Company's or Merger Sub's conditions under the Merger Agreement or change in any manner the voting rights of any class of shares of the Company (including any amendments to the Company’s articles of incorporation or bylaws).

(b)     Each Stockholder hereby appoints Parent and any designee of Parent, and each of them individually, as proxies and attorneys-in-fact, with full power of substitution and re substitution, to vote (or act by written consent) during the term of this Agreement with respect to the Shares in accordance with Section 3(a). This proxy and power of attorney is given to secure the performance of the duties of the Stockholders under this Agreement. Each Stockholder shall take such further action or execute such other instruments as may be necessary to effectuate the intent of this proxy. This proxy and power of attorney granted by the Stockholders shall be irrevocable during the term of this Agreement, shall be deemed to be coupled with an interest sufficient in law to support an irrevocable proxy and shall revoke any and all prior proxies granted by a Stockholder with respect to such Stockholder’s Shares. The power of attorney granted by a Stockholder herein is a durable power of attorney and shall survive the dissolution, bankruptcy, death or incapacity of such Stockholder. The proxy and power of attorney granted hereunder shall terminate upon the termination of this Agreement.

Each Stockholder agrees that such Stockholder will not, and will not permit any entity under such Stockholder's control to, deposit any of such Stockholder’s Shares in a voting trust, grant any proxies with respect to such Stockholder’s Shares or subject any of such Stockholder’s Shares to any arrangement with respect to the voting of such Shares other than agreements entered into with Parent.

 Each Stockholder agrees that during the term of this Agreement, such Stockholder will not, directly or indirectly, transfer, sell, offer, exchange, assign, pledge or otherwise dispose of or encumber (“Transfer”) any of such Stockholder’s Shares or enter into any contract, option or other agreement with respect to, or consent to, a Transfer of, any of such Stockholder’s Shares or such Stockholder's voting or economic interest therein. Any attempted Transfer of a Stockholder’s Shares or any interest therein in violation of this Section 5 shall be null and void. This Section 5 shall not prohibit a Transfer of a Stockholder’s Shares by such Stockholder to any member of such Stockholder's immediate family, or to a trust for the benefit of such Stockholder or any member of such Stockholder's immediate family, or upon the death of such Stockholder; provided, that a Transfer referred to in this sentence shall be permitted only if, as a precondition to such Transfer, the transferee agrees in a writing, reasonably satisfactory in form and substance to Parent, to be bound by all of the terms of this Agreement.

Each Stockholder agrees that all shares of Company Common Stock that such Stockholder purchases, acquires the right to vote or otherwise acquires beneficial ownership (as defined in Rule 13d-3 under the Exchange Act) of after the execution of this Agreement shall be subject to the terms of this Agreement and shall constitute Shares for all purposes of this Agreement.

Each Stockholder hereby waives, and agrees not to assert or perfect, any rights of appraisal or rights to dissent from the Merger that such Stockholder may have by virtue of ownership of such Stockholder’s Shares.

This Agreement shall terminate upon the earliest to occur of (i) the Effective Time, and (ii) the date on which the Merger Agreement is terminated in accordance with its terms.

No Stockholder makes any agreement or understanding in this Agreement in such Stockholder's capacity as a director or officer of the Company or any of its subsidiaries (if such Stockholder holds such office), and nothing in this Agreement: (a) will limit or affect any actions or omissions taken by such Stockholder in such Stockholder's capacity as such a director or officer, including in exercising rights under the Merger Agreement, and no such actions or omissions shall be deemed a breach of this Agreement or (b) will be construed to prohibit, limit or restrict such Stockholder from exercising such Stockholder's fiduciary duties as an officer or director to the Company or its stockholders.

 Each party hereto acknowledges that it will be impossible to measure in money the damage to the other party if a party hereto fails to comply with any of the obligations imposed by this Agreement, that every such obligation is material and that, in the event of any such failure, the other party will not have an adequate remedy at law or damages. Accordingly, each party hereto agrees that injunctive relief or other equitable remedy, in addition to remedies at law or damages, is the appropriate remedy for any such failure and will not oppose the seeking of such relief on the basis that the other party has an adequate remedy at law. Each party hereto agrees that it will not seek, and agrees to waive any requirement for, the securing or posting of a bond in connection with the other party's seeking or obtaining such equitable relief.

This Agreement supersedes all prior agreements, written or oral, between the parties hereto with respect to the subject matter hereof and contains the entire agreement between the parties with respect to the subject matter hereof. This Agreement may not be amended or supplemented, and no provisions hereof may be modified or waived, except by an instrument in writing signed by all of the parties hereto. No waiver of any provisions hereof by any party shall be deemed a waiver of any other provisions hereof by such party, nor shall any such waiver be deemed a continuing waiver of any provision hereof by such party.

All notices, requests, claims, demands, and other communications hereunder shall be in writing and shall be deemed to have been given (a) when delivered by hand (with written confirmation of receipt), (b) when received by the addressee if sent by a nationally recognized overnight courier (receipt requested), (c) on the date sent by e-mail of a PDF document (with confirmation of transmission) if sent during normal business hours of the recipient, and on the next Business Day if sent after normal business hours of the recipient, or (d) on the third day after the date mailed, by certified or registered mail, return receipt requested, postage prepaid.
