The Stockholder covenants and agrees that, (x) except for this Agreement the Stockholder shall not enter into, during the Support Period, any voting agreement or voting trust with respect to any Subject Shares, (y) except as expressly set forth herein, the Stockholder shall not grant, during the Support Period, a proxy, consent or power of attorney with respect to any Subject Shares, or (z) during the Support Period, the Stockholder shall not take (or knowingly refrain from taking) any other action with respect to the Subject Shares or the Stockholder, in the case of each of clauses (x), (y) and (z), except as would not, individually or in the aggregate, reasonably be expected to restrict in any material respect, prohibit, impair in any material respect or materially delay the performance by the Stockholder of his obligations under this Agreement.

(b) In furtherance, and not in limitation of the foregoing, during the Support Period, the Stockholder shall execute and deliver (or cause the holders of record to execute and deliver), promptly upon receipt (and in any event within five Business Days after receipt thereof), any proxy card or voting instructions he receives that are sent to stockholders of the Company soliciting proxies with respect to any matter described in Section 3(a), which shall be voted in the manner described in Section 3(a) (with Parent to be promptly notified (and provided reasonable evidence) of such execution and delivery of such proxy card or voting instructions); provided, that such proxy card or voting instructions shall not be expressed to be irrevocable or similar.

(c) Nothing in this Agreement shall obligate the Stockholder to exercise any option or any other right to acquire any shares of Company Common Stock.

SECTION 4 Non-Solicitation. The Stockholder hereby agrees, and agrees to cause his controlled Affiliates (which, for the avoidance of doubt, does not include the Company or any of its Subsidiaries or their Representatives) and to use his reasonable best efforts to cause his and their Representatives, immediately upon the Non-Solicitation Start Date until the Expiration Time, not to take any action which, were it taken by the Company, its Subsidiaries or its or their Representatives, would violate Section 6.02(b) of the Merger Agreement as such provision is drafted as of the date of this Agreement. For the avoidance of doubt, nothing in this Section 4 shall restrict the Stockholder and his controlled Affiliates and their respective Representatives from engaging in any actions that the Company, its Subsidiaries or its or their Representatives are permitted to engage in under Section 6.02(c) of the Merger Agreement with respect to any bona fide unsolicited written Acquisition Proposal received by the Company from a Third Party that the Company Board (or any duly authorized committee thereof) determines in good faith, after consultation with the Company’s outside legal and financial advisors, constitutes, or would reasonably be expected to lead to, a Superior Proposal, and that the Company Board determines in good faith, after consultation with its outside legal counsel, that failure to take such action would reasonably be expected to be inconsistent with the fiduciary duties of the Company Board under Delaware law, including participating in discussions and negotiations with, providing information and data to and otherwise facilitating any Person making such Acquisition Proposal (or its Representatives) in conjunction with and ancillary to the Company’s discussions and negotiations with such Person.

SECTION 5 Directors and Officers. Notwithstanding any provision of this Agreement to the contrary, nothing in this Agreement (including Section 4 hereof) shall (or shall require the Stockholder to attempt to) limit or restrict the Stockholder in his capacity as a director or officer of the Company or any designee of, or individual that is a Representative of or otherwise affiliated with, the Stockholder who is a director or officer of the Company, from acting in such capacity and exercising his rights or fiduciary duties as a director or officer of the Company or voting in such person’s sole discretion on any matter (it being understood that this Agreement shall apply to the Stockholder solely in the Stockholder’s capacity as stockholder of the Company and that any director or officer of the Company who signs this Agreement as the Stockholder, or on behalf of the Stockholder, is signing only as the Stockholder (or on behalf of the Stockholder) and not in any other capacity). No action (or inaction) taken by the Stockholder or any designee or Representative of, or Person otherwise affiliated with, the Stockholder who is a director or officer of the Company, in their capacity as a director or officer of the Company, shall be deemed to constitute a breach of this Agreement.

SECTION 6 No Ownership Interest. Nothing contained in this Agreement shall be deemed to vest in Parent or Merger Sub any direct or indirect ownership or incidence of ownership of or with respect to any Subject Shares. All rights, ownership and economic benefits of and relating to the Subject Shares shall remain vested in and belong to the Stockholder, and neither Parent nor Merger Sub shall have the authority by virtue of this Agreement or the transactions to be consummated pursuant hereto to manage, direct, superintend, restrict, regulate, govern, or administer any of the policies or operations of the Company or exercise any power or authority to direct the Stockholder in the voting of any of the Subject Shares to the extent such Subject Shares are entitled to be voted, except as expressly provided herein.

SECTION 7 Representations and Warranties of the Stockholder. The Stockholder solely on his own behalf hereby represents and warrants to Parent and Merger Sub as follows:

(a) Power; Binding Agreement. The Stockholder has full legal capacity to execute and deliver this Agreement and to perform the Stockholder’s obligations hereunder. This Agreement has been duly executed and delivered by the Stockholder, and, assuming this Agreement constitutes a valid and binding obligation of Parent and Merger Sub, constitutes a valid and binding obligation of the Stockholder, enforceable against the Stockholder in accordance with its terms, subject to the Bankruptcy and Equity Exceptions.

(b) No Conflicts. None of the execution and delivery by the Stockholder of this Agreement or the performance by the Stockholder of his obligations hereunder will (i) result in a violation or breach of, or constitute (with or without notice or lapse of time or both) a default (or give rise to any third party right of termination, cancellation, material modification or acceleration) under any of the terms, conditions or provisions of any note, loan agreement, bond, mortgage, indenture, commitment, arrangement, understanding or other agreement to which the Stockholder is a party or by which the Stockholder or any of the Stockholder’s properties or assets may be bound, or (ii) violate any Order or Applicable Law applicable to the Stockholder or any of the Stockholder’s properties or assets, except, in the case of each of the foregoing clauses (i) and (ii), as would not, individually or in the aggregate, reasonably be expected to prevent or materially delay the performance by the Stockholder of his obligations hereunder.

(c) Ownership of Shares. Such Stockholder (together with his spouse, as set forth on Schedule I of this Agreement) is the record and/or beneficial owner of the shares of Company Common Stock as of the date hereof set forth opposite the Stockholder’s name on Schedule I of this Agreement, all of which are free and clear of any Encumbrances (other than Permitted Encumbrances) other than any Encumbrances that would not prevent or delay the Stockholder’s ability to perform the Stockholder’s obligations hereunder.

None of the shares of Company Common Stock indicated on Schedule I of this Agreement are subject to any stockholders’ agreement, proxy, voting trust or other agreement or arrangement with respect to the voting of such Subject Shares except as would not, individually or in the aggregate, reasonably be expected to restrict in any material respect, prohibit, impair in any material respect or materially delay the performance by the Stockholder of its obligations under this Agreement.

(f) Reliance. The Stockholder has been represented by or had the opportunity to be represented by, independent counsel of his own choosing, and he has had the full right and opportunity to consult with his attorney, to the extent, if any, that he desired, he availed himself of this right and opportunity, he has carefully read and fully understand this Agreement and the Merger Agreement in its entirety and have had it fully explained to him by his counsel, that he is fully aware of the contents thereof and its meaning, intent and legal effect, and that he is competent to execute this Agreement and has executed this Agreement free from coercion, duress or undue influence.

(h) Brokers. No broker, finder, financial advisor, investment banker or other Person is entitled to any brokerage, finder’s, financial advisor’s or other similar fee or commission from Parent, Merger Sub or the Company in connection with the transactions contemplated by this Agreement based upon arrangements made by or on behalf of the Stockholder (other than as an officer or director of the Company).

Each party hereto agrees that notice or the service of process in any Proceeding out of or relating to this Agreement or the performance of the obligations contemplated hereby shall be properly served or delivered if delivered in the manner contemplated by Section 13(g) or in any other manner permitted by law.
