WHEREAS, as a condition to its willingness to enter into the Merger Agreement, Company has requested that Stockholder enter into this Agreement pursuant to which Stockholder shall, among other things, vote all of the shares of Parent Common Stock held by Stockholder in favor of the issuance of Parent Common Stock in the Merger.

This Agreement has been duly authorized, executed and delivered by Company and constitutes a valid and binding obligation of Company enforceable against Company in accordance with its terms.

Section 4. Covenants of Stockholder. Subject to Section 9 hereof, Stockholder agrees as follows:

(a) Without in any way limiting Stockholder's right to vote the Subject Shares in its sole discretion on any other matters that may be submitted to a stockholder vote, consent or other approval (including by written consent), at any meeting of the stockholders of Parent called upon to approve and adopt the Merger Agreement and the Merger, and to approve the issuance of Parent Common Stock in connection with the Merger or at any adjournment thereof or in any other circumstances upon which a vote, consent or other approval (including written consent) with respect to the Merger Agreement and the Merger is sought, Stockholder shall vote (or cause to be

voted) the Subject Shares (which number of shares may be greater or less than the number of shares as of the date hereof):

(i) in favor of the Merger, the approval and adoption by Parent of the Merger Agreement, approval of the issuance of Parent Common Stock in connection with the Merger and approval of the other transactions contemplated by the Merger Agreement; and

(ii) against any amendment of Parent's certificate of incorporation or by-laws or equivalent organizational documents or other proposal or transaction involving Parent or any of its Subsidiaries which amendment or other proposal or transaction would or could reasonably be expected to impede, frustrate, prevent, nullify or result in a breach of any representation, warranty or covenant or any other obligation or agreement of Parent Company under or with respect to, the Merger, the Merger Agreement, the issuance of Parent Common Stock in connection with the Merger or any of the transactions contemplated by the Merger Agreement or by this Agreement.

(b) Stockholder agrees not to transfer, sell, assign, exchange, pledge or otherwise dispose of or encumber any of the Subject Shares, or to make any offer or agreement relating thereto, at any time prior to the termination of this Agreement. Notwithstanding the foregoing, (i) Stockholder may, during the term of this Agreement, gift, sell or otherwise transfer the Subject Shares to (x) a member or members of a group consisting of Stockholder's spouse, Stockholder's issue, the spouses of Stockholder's issue or any charitable organization, (y) any trust or custodian account created for the primary benefit of any one or more of Stockholder or the permitted transferees described in clause (x) above or (z) a general partnership, limited partnership, limited liability company or other business entity, all of the equity interests of which are held by Stockholder or the permitted transferees described in clause (x) above, and (ii) a Stockholder who acquired Subject Shares pursuant to this sentence may transfer such Subject Shares only to the Stockholder from whom, directly or indirectly, such transferring Stockholder acquired said Subject Shares or parties to whom such transferring Stockholder is permitted to transfer Parent Common Stock pursuant to this sentence; provided, however, in the case of any gift, sale or other transfer pursuant to this paragraph, at the time of and as a condition to such gift, sale or other transfer, the permitted transferee shall provide to Company its written agreement to be bound by the terms of this Agreement and to perform all of the obligations of Stockholder set forth herein as if the permitted transferee had originally executed and delivered this Agreement to Company. Furthermore, Stockholder shall not, except as contemplated by this Agreement, directly or indirectly, grant any proxies or powers of attorney with respect to the Subject Shares, deposit the Subject Shares into a voting trust or enter into a voting agreement or any other arrangement with respect to the Subject Shares.

Section 5. Certain Events. Stockholder agrees that this Agreement and the obligations hereunder shall attach to the Subject Shares and shall be binding upon any person or entity to which legal or beneficial ownership of such Subject Shares shall pass, whether by operation of law or otherwise, including the respective successors of Stockholder. In the event of any stock split, stock dividend, merger, reorganization, recapitalization or other change in the capital structure of Parent affecting the Parent Common Stock or the acquisition of additional shares of Parent Common Stock or other voting securities of Parent by Stockholder (whether by purchase, conversion or otherwise), the number of Subject Shares shall be adjusted appropriately and this Agreement and the obligations hereunder shall attach to any additional or decreased shares of Parent Common Stock or other voting securities of Parent issued to or acquired or disposed of by Stockholder.

Section 6. Stockholder Capacity. Stockholder enters into this Agreement solely in Stockholder's capacity as the record and beneficial owner of the Subject Shares. If any Stockholder is or becomes during the term hereof a director or officer of Parent, such Stockholder makes no agreement or

understanding in this Agreement in Stockholder's capacity as such director or officer. Nothing in this Agreement shall limit or affect any actions taken by Stockholder in Stockholder's capacity as an officer or director of Parent.

Section 7. No Ownership Interest. Except as expressly set forth in this Agreement, nothing contained in this Agreement shall be deemed to vest in Company 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 any Subject Shares shall remain and belong to Stockholder, and Company shall not have any authority to exercise any power or authority to manage, direct, superintend, restrict, regulate, govern or administer any of the policies or operations of Parent or exercise any power or authority to direct Stockholder in the voting of any of the Subject Shares, except as otherwise expressly provided in this Agreement.

Section 8. Assignment. Neither this Agreement nor any of the rights, interests or obligations hereunder shall be assigned, in whole or in part (whether by operation of law or otherwise), by Stockholder, on the one hand, without the prior written consent of Company nor by Company, on the other hand, without the prior written consent of Stockholder, and any attempt to make any such assignment without such consent shall be null and void; provided that Company may assign, in its sole discretion, any or all of its rights, interests and obligations hereunder to any direct or indirect wholly owned subsidiary of Company. Subject to the preceding sentence, this Agreement will be binding upon, inure to the benefit of and be enforceable by the parties and their respective successors and assigns.

Section 9. Termination. This Agreement shall terminate, and the provisions hereof shall be of no further force or effect, upon the earlier of the Effective Time or the termination of the Merger Agreement in accordance with Article IX thereof (including the payment of the Termination Fee, if applicable); provided, however, that notwithstanding anything to the contrary contained in this Agreement, no party hereto shall be relieved of or released from any liabilities or damages arising out of a willful and material breach of its covenants or a willful and material breach of its representations or warranties contained in this Agreement prior to the termination of this Agreement.
