Capitalized terms used but not otherwise defined herein shall have the meanings given to such terms in the Merger Agreement (as defined below).

WHEREAS, in order to induce Parent and Alpha Medical Merger Sub, Inc., a Delaware corporation and a wholly owned subsidiary of Parent (“Merger Sub”), to enter into an Agreement and Plan of Merger, dated as of the date hereof (the “Merger Agreement”), with the Company, Parent has requested each Stockholder, and each Stockholder has agreed, to enter into this Agreement with respect to the number of shares of common stock, par value $0.10 per share, of the Company (the “Shares”) that such Stockholder beneficially owns and are set forth next to such Stockholder’s name on Schedule A (together with such additional Shares or voting securities of which such Stockholder acquires record or beneficial ownership after the date hereof, such Stockholder’s “Subject Shares”).

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

ARTICLE 1

GRANT OF PROXY; VOTING AGREEMENT

Section 1.01. Voting Agreement. Beginning on the date hereof until the Expiration Date, each Stockholder hereby irrevocably and unconditionally agrees that at any meeting of the stockholders of the Company, however called, and at any adjournment thereof, at which the Merger Agreement (or any amended version thereof) or the Transactions, are submitted for the consideration and vote of the stockholders of the Company, or in any other circumstance in which the vote or other approval of the stockholders of the Company is sought, each Stockholder shall, in each case to the fullest extent that its Subject Shares are entitled to vote thereon, (a) appear at such meeting or otherwise cause its Subject Shares to be counted as present thereat for purposes of calculating a quorum, (b) vote (or cause to be voted), in person or by proxy, all Subject Shares that such Stockholder is entitled to vote at the time of any vote (i) in favor of the approval and adoption (as applicable) of the Merger Agreement and any actions related thereto, (ii) in favor of any proposal to adjourn a meeting of the stockholders of the Company to solicit additional proxies in favor of the approval and adoption (as applicable) of the Merger Agreement and any actions related thereto, and (iii) against any (1) Acquisition Proposal, (2) reorganization, recapitalization, liquidation or winding-up

of the Company or any other extraordinary transaction involving the Company, (3) action or agreement the consummation of which would reasonably be expected to prevent or delay the consummation of the Transactions, (4) any action or agreement that would reasonably be expected to result in a material breach or violation of any covenant, representation or warranty or any other obligation of such Stockholder contained in this Agreement, or (5) any change in the membership of the Company Board, unless approved by Parent.

Section 1.02. Irrevocable Proxy. Each Stockholder hereby revokes any and all previous proxies granted with respect to its Subject Shares (and such Stockholder hereby represents that any such prior proxy is revocable). By entering into this Agreement, such Stockholder hereby grants a proxy appointing Parent as such Stockholder’s attorney-in-fact and proxy, with full power of substitution, for and in such Stockholder’s name, to vote, express dissent, or otherwise to utilize such voting power in the manner contemplated by Section 1.01 as Parent or its proxy or substitute shall, in Parent’s sole discretion, deem proper with respect to the Subject Shares; provided that (a) Parent shall not exercise the proxy granted by such Stockholder under this Section 1.02 more than ten (10) Business Days prior to the Company Stockholders’ Meeting unless such Stockholder fails to comply with his obligation under this Agreement or attempts or purports to vote the Subject Shares in a manner inconsistent with Section 1.01 and (b) if Parent intends to exercise the proxy granted by such Stockholder under this Section 1.02 between the tenth (10^th) Business Day and the second (2^nd) Business Day prior to the Company Stockholders’ Meeting, Parent shall provide the applicable Stockholder with written notice at least twenty-four (24) hours prior to exercising such proxy. The proxy granted by such Stockholder pursuant to this Article 1 is irrevocable and is granted in consideration of Parent entering into the Merger Agreement and incurring certain related fees and expenses. The proxy granted by such Stockholder shall automatically be revoked upon the Expiration Date. Each Stockholder hereby ratifies and confirms all actions that the proxy appointed hereunder may lawfully do or cause to be done in accordance with this Section 1.02. Each Stockholder intends this proxy to be irrevocable and unconditional during the term of this Agreement and coupled with an interest and will take such further action or execute such other instruments as may be reasonably necessary to effect the intent of this proxy. Each Stockholder hereby agrees not to grant any proxy during the term of this Agreement with respect to any Subject Shares that is inconsistent with the proxy granted pursuant to this Section 1.02. Any attempt by such Stockholder to grant a proxy, vote or express dissent with respect to (or otherwise to utilize the voting power of) its Subject Shares in a manner inconsistent with the proxy granted pursuant to this Section 1.02 shall be null and void ab initio.

ARTICLE 2

The execution, delivery and performance by such Stockholder of this Agreement and the consummation by such Stockholder of the transactions contemplated hereby are within the organizational or individual powers of such Stockholder and have been duly authorized by all necessary action on the part of such Stockholder. This Agreement constitutes a legal, valid and binding Agreement of such Stockholder, enforceable against such Stockholder in accordance with its terms, subject, in the case of enforceability, to the Enforceability Exceptions. If such Stockholder is married and the Subject Shares set forth on Schedule A hereto opposite such Stockholder’s name constitute community property under applicable Law, this Agreement has been duly authorized, executed and delivered by, and constitutes the valid and binding agreement of, such Stockholder’s spouse. If this Agreement is being executed in a representative or fiduciary capacity, the Person signing this Agreement has full power and authority to enter into and perform this Agreement. Other than as provided in the Merger Agreement and except for any filings by such Stockholder with the SEC, the execution, delivery and performance by such Stockholder of this Agreement do not require any action by or in respect of, or any notice, report or other filing by such Stockholder with or to, or any consent, registration, approval, permit or authorization from, any Governmental Authority, other than any actions or filings the absence of which would not reasonably be expected to, individually or in the aggregate, prevent, delay or impair such Stockholder’s ability to perform its obligations hereunder.

Section 2.02. Non-Contravention. The execution, delivery and performance by such Stockholder of this Agreement and the performance of its obligations hereunder do not and will not (i) if such Stockholder is an entity, violate the certificate of incorporation or bylaws (or other comparable organizational documents) of such Stockholder, (ii) violate any Law applicable to such Stockholder, or (iii) require any consent, payment, notice to, or other action by any Person under, constitute a default under, or give rise to any right of termination, cancellation or acceleration or to a loss of any benefit to which such Stockholder is entitled under any provision of any Contract to which such Stockholder is a party, in each case of this clause (iii), other than such consents, payments, notices to, or other actions that (A) have been duly obtained prior to the execution and delivery of this Agreement or (B) would not reasonably be expected to, individually or in the aggregate, prevent, delay or impair such Stockholder’s ability to perform its obligations hereunder.

Except for this Agreement, none of such Stockholder’s Subject Shares are subject to any voting agreement, voting trust or other agreement or arrangement, including any proxy, consent or power of attorney.

Section 2.07. Finder’s Fees. No investment banker, broker, finder or other intermediary is entitled to a fee or commission from any member of the Company Group in respect of this Agreement or the Transactions based upon any arrangement or agreement made by or on behalf of such Stockholder in such Stockholder’s capacity as such.

Section 5.05. Amendments; Termination. Any provision of this Agreement may be amended or waived if, but only if, such amendment or waiver is in writing and is signed, in the case of an amendment, by each party to this Agreement or in the case of a waiver, by the party against whom the waiver is to be effective. This Agreement shall automatically terminate without further action of any party hereto upon the earlier of (i) the Effective Time, (ii) the termination of the Merger Agreement in accordance with its terms, (iii) as to any Stockholder, any amendment to the Merger Agreement that reduces the amount of or changes the form of, or imposes any material restrictions or conditions on the payment of, the Merger Consideration or extends the Outside Date, in each case, unless such amendment has been consented to by such Stockholder, or (iv) the mutual written agreement of each party to this Agreement (any such date under clauses (i) through (iv) being referred to herein as the “Expiration Date”). Notwithstanding the foregoing, (i) the provisions set forth in this Article 5 shall survive the termination of this Agreement and (ii) no termination of this Agreement shall relieve any party hereto from liability, or otherwise limit the liability of any party hereto, for any Willful Breach of this Agreement that occurred prior to the Expiration Date.

Section 5.07. Successors and Assigns. Neither this Agreement nor any of the rights, interests or obligations under this Agreement shall be assigned, in whole or in part, by operation of Law or otherwise by any of the parties without the prior written consent of the other parties. Any purported assignment without such consent shall be void. Subject to the preceding sentences, this Agreement will be binding upon, inure to the benefit of, and be enforceable by, the parties and their respective successors and assigns.

Section 5.08. Governing Law. This Agreement and all Actions arising under this Agreement shall be governed by and construed in accordance with the Laws of the State of Delaware, without giving effect to any applicable principles of conflict of laws that would cause the applicable Laws of another jurisdiction other than the State of Delaware to otherwise govern this Agreement.

Section 5.09. Jurisdiction. The parties agree that any suit, action or proceeding seeking to enforce any provision of, or based on any matter arising out of or in connection with, this Agreement (whether brought by any party or any of its Affiliates or against any party or any of its Affiliates) shall be heard and determined exclusively in the Delaware Court of Chancery; provided, however, that if the Delaware Court of Chancery does not have jurisdiction over such Action, such Action shall be heard and determined

exclusively in the United States District Court for the District of Delaware. Consistent with the preceding sentence, each of the parties hereby (i) submits to the exclusive jurisdiction of such courts for the purpose of any Action arising out of or relating to this Agreement brought by either party; (ii) agrees that service of process will be validly effected by sending notice in accordance with Section 5.04; and (iii) irrevocably waive, and agree not to assert by way of motion, defense, or otherwise, in any such Action, any claim that it is not subject personally to the jurisdiction of the above-named courts, that its property is exempt or immune from attachment or execution, that the Action is brought in an inconvenient forum, that the venue of the Action is improper, or that this Agreement or the Transactions may not be enforced in or by any of the above-named courts. Process in any such Action may be served on any party anywhere in the world, whether within or without the jurisdiction of any such court. Without limiting the foregoing, each party agrees that service of process on such party as provided in Section 5.04 shall be deemed effective service of process on such party.

Section 5.10. WAIVER OF JURY TRIAL. EACH OF THE PARTIES HEREBY WAIVES TO THE FULLEST EXTENT PERMITTED BY APPLICABLE LAW ANY RIGHT IT MAY HAVE TO A TRIAL BY JURY WITH RESPECT TO ANY LITIGATION DIRECTLY OR INDIRECTLY ARISING OUT OF, UNDER OR IN CONNECTION WITH THIS AGREEMENT. EACH OF THE PARTIES HEREBY (A) CERTIFIES THAT NO REPRESENTATIVE, AGENT OR ATTORNEY OF ANY OTHER PARTY HAS REPRESENTED, EXPRESSLY OR OTHERWISE, THAT SUCH OTHER PARTY WOULD NOT, IN THE EVENT OF LITIGATION, SEEK TO ENFORCE THE FOREGOING WAIVER AND (B) ACKNOWLEDGES THAT IT HAS BEEN INDUCED TO ENTER INTO THIS AGREEMENT, AS APPLICABLE, BY, AMONG OTHER THINGS, THE MUTUAL WAIVERS AND CERTIFICATIONS IN THIS SECTION 5.10.

Section 5.11. Counterparts. This Agreement may be executed and delivered (including by electronic transmission, such as by electronic mail in “pdf” form) in counterparts, and by the different parties in separate counterparts, each of which when executed shall be deemed to be an original but all of which taken together shall constitute one and the same agreement.

Section 5.12. Severability. If any term or other provision of this Agreement is invalid, illegal or incapable of being enforced by any rule of Law, or public policy, all other conditions and provisions of this Agreement shall nevertheless remain in full force and effect so long as the economic or legal substance of the transactions contemplated hereby is not affected in any manner materially adverse to any party. Upon such determination that any term or other provision is invalid, illegal or incapable of being enforced, the parties shall negotiate in good faith to modify this Agreement so as to effect the original intent of the parties as closely as possible in a mutually acceptable manner in order that the transactions contemplated hereby be consummated as originally contemplated to the fullest extent possible.

Section 5.13. Specific Performance. The parties acknowledge and agree that irreparable damage would occur in the event that any of the provisions of this Agreement were not performed in accordance with their specific terms or were otherwise breached. Each party agrees that, in the event of any breach or threatened breach by any other party of any covenant or obligation contained in this Agreement, the non-breaching party shall be entitled (in addition to any other remedy that may be available to it whether in law or equity, including monetary damages) to (a) specific performance to enforce the observance and performance of such covenant or obligation and (b) an injunction restraining such breach or threatened breach. Each party further agrees that no other party or any other person 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 Section 5.13, and each party irrevocably waives any right it may have to require the obtaining, furnishing or posting of any such bond or similar instrument. Each party hereto hereby waives and agrees not to assert any objections to any remedy referred to in this Section 5.13 (including any objection on the basis that there is an adequate remedy at law or that an award of such remedy is not an appropriate remedy for any reason at law or equity).
