The term “Shares” shall mean all issued and outstanding shares of Company Common Stock owned of record and beneficially owned by Stockholder or over which Stockholder exercises sole voting power, in each case, as of the date of this Agreement. Stockholder agrees that any shares of capital stock of the Company that Stockholder purchases or with respect to which Stockholder otherwise acquires beneficial ownership or over which Stockholder exercises sole voting power after the date of this Agreement and prior to the termination of this Agreement pursuant to Section 4 below shall be subject to the terms and conditions of this Agreement to the same extent as if they constituted Shares as of the date hereof.

     1.2 Agreement to Vote Shares. Stockholder hereby covenants and agrees that during the period commencing on the date hereof and continuing until this Agreement terminates pursuant to Section 4 hereof, at any meeting (whether annual or special and whether or not an adjourned or postponed meeting) of the stockholders of the Company, however called, and in any action by written consent of the stockholders of the Company, Stockholder shall appear at the meeting or otherwise cause any and all Shares to be counted as present thereat for purposes of establishing a quorum and vote (or cause to be voted) any and all Shares: (i) in favor of the Company Stockholder Proposal (to the extent it relates solely to the approval of the Merger and the Merger Agreement); and (ii) against any of the following (or any agreement to enter into, effect, facilitate or support any of the following): (A) any Acquisition Proposal; (B) any merger agreement or merger (other than the Merger Agreement and the Merger), consolidation,

combination, sale of substantial assets, reorganization, recapitalization, dissolution, liquidation or winding up of or by the Company; or (C) any amendment of the Company’s Certificate of Incorporation or Bylaws or any other proposal or transaction involving the Company, the purpose of which amendment or other proposal or transaction is to delay, prevent or nullify the Merger or the transaction contemplated by the Merger Agreement or change in any manner the voting rights of any capital stock of the Company (collectively, “Frustrating Transactions”). Stockholder further agrees not to enter into any written or oral agreement with any person or entity the effect of which would be inconsistent with or violative of any provision contained in this Section 1.2. Any vote by the Stockholder that is not in accordance with this Section 1.2 shall be considered null and void.

In the event of any change in the number of issued and outstanding shares of Company Common Stock by reason of any stock split, reverse split, stock dividend (including any dividend or distribution of securities convertible into Company Common Stock), combination, reorganization, recapitalization or other like change, conversion or exchange of shares, or any other change in the corporate or capital structure of the Company, the term “Shares” shall be deemed to refer to and include the Shares as well as all such stock dividends and distributions and any shares into which or for which any or all of the Shares may be changed or exchanged.

2. Other Restrictions.

     3.2 Non-Contravention. The execution, delivery and performance of this Agreement does not, and the consummation of the transactions contemplated hereby and compliance with the provisions hereof will not, contravene, conflict with, or result in any violation of, breach of or default by (with or without notice or lapse of time, or both) Stockholder under, or give rise to a right of termination, cancellation or acceleration of any obligation under, or result in the creation of any Lien (other than pursuant to this Agreement) upon any of the properties or assets of Stockholder under, any provision of (i) any loan or credit agreement, note, bond, mortgage, indenture, lease or other agreement, instrument, permit, concession, franchise or license applicable to Stockholder or (ii) any judgment, order, decree, statute, law, ordinance, injunction, rule or regulation applicable to Stockholder or any of Stockholder’s properties or assets, other than any such conflicts, violations, defaults, rights, or Liens that, individually or in the aggregate, would not impair the ability of Stockholder to perform Stockholder’s obligations hereunder or prevent, limit or restrict in any respect the consummation of any of the transactions contemplated hereby. There is no beneficiary or holder of a voting trust certificate or other interest of any trust of which Stockholder is settlor or trustee or any other person or entity, including any Governmental Entity, whose consent, approval, order or authorization is required by or with respect to Stockholder for the execution, delivery and performance of this Agreement by Stockholder or the consummation by Stockholder of the transactions contemplated hereby.

4. Effectiveness; Termination; No Survival. This Agreement shall become effective upon its execution by Stockholder and Parent. This Agreement may be terminated at any time by mutual written consent of Stockholder and Parent. This Agreement, and the obligations of Stockholder hereunder, including, without limitation, Stockholder’s obligations under Section 1 and Section 2 above, shall terminate, without any action by the parties hereto, upon the earlier to occur of the following: (i) the Effective Time; (ii) such date and time as the Merger Agreement shall have been validly terminated pursuant to Article VII thereof; and (iii) the entry by the Company into any amendment or modification to the Merger Agreement that materially and adversely affects Stockholder that has not been previously approved in writing by Stockholder, provided that, Section 6 shall survive a termination of this Agreement under clause (i) above. Nothing in this Section 4 shall relieve any party of liability for breach of this Agreement.

5. Further Assurances. Subject to the terms of this Agreement, from time to time, Stockholder shall execute and deliver such additional documents and use commercially reasonable efforts to take, or cause to be taken, all such further actions, and to do or cause to be done, all things reasonably necessary, proper or advisable under applicable laws and regulations to consummate and make effective the transactions contemplated by this Agreement.

6. Miscellaneous.

     6.1 Severability. If any term, provision, covenant or restriction of this Agreement is held by a court of competent jurisdiction to be invalid, void or unenforceable, the remainder of the terms, provisions, covenants and restrictions of this Agreement shall remain in full force and effect and shall in no way be affected, impaired or invalidated, 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, void or unenforceable, the parties hereto shall negotiate in good faith to modify this Agreement so as to effect the original intent of the parties as closely as possible in an acceptable manner to the end that transactions contemplated hereby are fulfilled to the extent possible.

     6.2 Binding Effect and Assignment.

     6.4 Specific Performance; Injunctive Relief; Attorneys Fees. The parties hereto acknowledge that Parent will be irreparably harmed and that there will be no adequate remedy at law for a violation of any of the covenants or agreements of Stockholder set forth herein. Therefore, it is agreed that, in addition to any other remedies that may be available to Parent upon any such violation, Parent shall have the right to enforce such covenants and agreements by specific performance, injunctive relief or by any other means available to Parent at law or in equity and Stockholder hereby irrevocably and unconditionally waives any objection to Parent seeking so to enforce such covenants and agreements by specific performance, injunctive relief and other means.
