Each Company Preferred Stockholder severally covenants and agrees as follows:

Except as contemplated by this Agreement or the Merger Agreement, during the period beginning from the execution and delivery by the parties of this Agreement through the earlier of (1) the Effective Time, (2) the termination of the Merger Agreement or (3) the termination of this Agreement in accordance with Section 6.1, each Company Preferred Stockholder shall not (i) directly or indirectly, offer for sale, sell, transfer, tender, pledge, encumber, assign, or otherwise dispose of (each, a “Transfer”), or enter into any contract, option, or other arrangement or understanding (including any profit sharing arrangement) with respect to the Transfer of, any or all of such Company Preferred Stockholder’s Voting Shares or any other securities of the Company or any interest therein to any Person, other than pursuant to the Merger Agreement or the Offer, (ii) grant any proxies or powers of attorney, or any other authorization or consent with respect to any or all of such Company Preferred Stockholder’s Voting Shares that could reasonably be expected to impede, interfere with or prevent the Merger, (iii) deposit any of such Company Preferred Stockholder’s Voting Shares into a voting trust or enter into a voting agreement with respect to any of such Company Preferred Stockholder’s Voting Shares, other than pursuant to this Agreement or (iv) take any action that would make any representation or warranty of such Company Preferred Stockholder contained in this Agreement untrue or incorrect in any material respect or that would reasonably be expected to have the effect of preventing or disabling or delaying such Company Preferred Stockholder from performing such Company Preferred Stockholder’s obligations under this Agreement.

Each Company Preferred Stockholder agrees with, and covenants to, Parent and Purchaser that (i) this Agreement and the obligations hereunder shall attach to such Company Preferred Stockholder’s Voting Shares and shall be binding upon any person or entity to which legal or beneficial ownership

shall pass, whether by operation of law or otherwise, and (ii) such Company Preferred Stockholder shall not request that the Company register the transfer (book-entry or otherwise) of any certificate or uncertificated interest representing any or all of the Company Preferred Stockholder’s Voting Shares, unless such transfer is made in compliance with this Agreement.

Section 6.1. This Agreement and the covenants and agreements set forth in this Agreement (a) shall automatically (without any further action of the parties) terminate upon the termination of the Original Merger Agreement or the Merger Agreement in accordance with its terms and (b) shall be terminable by the Company Preferred Stockholders holding a majority of the Series D-1 Preferred Stock upon (i) any modification or amendment of the Merger Agreement that is adverse to the Company Preferred Stockholders in any material respect (including, without limitation, any reduction in the Offer Price), (ii) any waiver by the Company of any obligation of Parent or Purchaser under the Original Merger Agreement or the Merger Agreement, including, without limitation, any of the Conditions of the Offer set forth in Annex A of the Original Merger Agreement or the Merger Agreement, which such waiver is adverse to the Company Preferred Stockholders in any material respect or (iii) the occurrence of a Company Adverse Recommendation Change, provided that, in the case of clauses (i) and (ii), the Company Preferred Stockholders holding a majority of the Series D-1 Preferred Stock have not consented in writing to such modification, amendment or waiver, and except that any termination of this Agreement pursuant to this Section 6.1 shall not relieve any party from liability for any breach hereof prior to such termination. If this Agreement shall be terminated pursuant to this Section 6.1, no Sale shall occur.

ARTICLE VII

Miscellanous

Section 7.1. Governing Law; Jurisdiction; Waiver of Jury Trial.

(a) This Agreement shall be governed by, and construed in accordance with, the Laws of the State of Delaware applicable to Contracts executed in and to be performed entirely within that State, regardless of the laws that might otherwise govern under applicable principles of conflicts of laws.

(b) All Actions or Proceedings arising out of or relating to this Agreement shall be heard and determined in the Chancery Court of the State of Delaware, and the parties hereto hereby irrevocably submit to the exclusive jurisdiction of such court (and, in the case of appeals, appropriate appellate courts therefrom) in any such Action or Proceeding and irrevocably waive the defense of an inconvenient forum to the maintenance of any such Action or Proceeding. The consents to jurisdiction set forth in this paragraph shall not constitute general consents to service of process in the State of Delaware and shall have no effect for any purpose except as provided in this paragraph and shall not be deemed to confer rights on any Person other than the parties hereto. The parties hereto agree that a final judgment in any such Action or Proceeding shall be conclusive and may be enforced in other jurisdictions by suit on the judgment or in any other manner provided by applicable Law.

(c) Each of the parties hereto hereby irrevocably waives any and all rights to trial by jury in any legal proceeding arising out of or related to this Agreement.

Section 7.2. Specific Performance. Each Company Preferred Stockholder acknowledges and agrees that (a) the covenants, obligations and agreements of such Company Preferred Stockholder contained in this Agreement relate to special, unique and extraordinary matters, (b) Parent is and will be relying on such covenants, obligations and agreements in connection with entering into the Merger Agreement and the performance of Parent’s obligations under the Merger Agreement, and (c) a violation of any of the covenants, obligations or agreements of such Company Preferred Stockholder contained in this Agreement will cause Parent irreparable injury for which adequate remedies are not available at law. Therefore, each Company Preferred Stockholder agrees that Parent shall be entitled to an injunction, restraining order or such other equitable relief (without the requirement to post bond) as a court of competent jurisdiction may deem necessary or appropriate to restrain such Company Preferred Stockholder, as the case may be, from committing any violation of such covenants, obligations or agreements and to specifically enforce the terms of this Agreement. These injunctive remedies are cumulative and in addition to any other rights and remedies Parent may have under applicable law.

Section 7.3. Assignment; No Third Party Beneficiaries. This Agreement shall not be assignable or otherwise transferable by a party without the prior consent of the other parties, and any attempt to so assign or otherwise transfer this Agreement without such consent shall be void and of no effect; provided, however, that Parent may, in its sole discretion, assign or transfer all or any of its rights, interests and obligations under this Agreement to any direct or indirect wholly owned subsidiary of Parent, but no such assignment shall relieve Parent from its obligations under this Agreement. This Agreement shall be binding upon the respective heirs, successors, legal representatives and permitted assigns of the parties hereto. Nothing in this Agreement shall be construed as giving any Person, other than the parties hereto and their heirs, successors, legal representatives and permitted assigns, any right, remedy or claim under or in respect of this Agreement or any provision hereof; provided, however, that the Company shall be a third party beneficiary of

the obligations of the parties to this Agreement and shall be entitled to enforce those obligations as though a party hereto.

Section 7.4. Amendments, Waivers, etc. Neither this Agreement nor any term hereof may be amended other than by an instrument in writing signed by Parent, Purchaser and the Company Preferred Stockholders. No provision of this Agreement may be waived, discharged or terminated other than by an instrument in writing signed by the party against whom the enforcement of such waiver, discharge or termination is sought, except that this Agreement may be terminated as set forth in Section 6.1.

Section 7.5. Notices. All notices, requests and other communications to any party hereunder shall be in writing and shall be deemed given if delivered either personally, by facsimile transmission (with acknowledgment received), by electronic mail (with receipt confirmed) or by overnight courier (providing proof of delivery) to the parties at the following addresses:

Section 7.8. Severability.
