NOW, THEREFORE, in consideration of the representations, warranties, covenants and agreements set forth in this Agreement and for other good and valuable consideration, the receipt, sufficiency and adequacy of which are hereby acknowledged, the Parties agree as follows:

ARTICLE I
STOCKHOLDERS CONSENT;
AGREEMENT TO VOTE AND IRREVOCABLE PROXY

Section 1.1 Agreement to Vote

Each Stockholder hereby irrevocably and unconditionally agrees that, from the Effective Date until the earlier of (a) the time that the Company Stockholder Approval has been obtained and (b) termination of this Agreement in accordance with Section 4.1 (the Agreement Term), such Stockholder shall (i) take all such actions as may be reasonably required to cause each of such Stockholder’s Owned Shares to be present, in person or by proxy, at the Company Stockholders Meeting and (ii) at any Company Stockholders Meeting vote (or cause to be voted), to the extent entitled to vote thereon, all of such Stockholder’s Owned Shares:

(A) in favor of (I) adoption of the Merger Agreement and the Transactions, including the Mergers and (II) the approval of any proposal to adjourn such Company Stockholders Meeting to a later date if there are not sufficient votes for adoption of the Merger Agreement and the Transactions, including the Mergers; and

(B) against (I) any Company Alternative Transaction, (II) any action that would reasonably be expected to result in a breach of or failure to perform any representation, warranty, covenant or agreement of the Company under the Merger Agreement or of such Stockholder under this Agreement, (III) any action that would reasonably be expected to prevent, impede, frustrate, interfere with, delay, postpone or adversely affect the consummation of the Mergers or the other Transactions (in contravention of the terms and conditions of the Merger Agreement), (IV) any merger agreement or merger (other than the Merger Agreement and the Mergers), consolidation, combination, material business transaction, sale of assets, reorganization, recapitalization, dissolution, liquidation or winding up of the Company or any Company Subsidiary, and (V) any amendment of the Company’s organizational documents that would reasonably be expected to impair the ability of the Company, Parent, Merger Sub or Merger Sub LLC to complete the Mergers, or that would or would reasonably be expected to prevent, impede, frustrate, interfere with, delay, postpone or adversely affect the consummation of the Mergers.

Section 1.2 Other Voting Rights

For the avoidance of doubt, except as expressly set forth in this Agreement, nothing in this Agreement shall limit the right of any Stockholder to vote in favor of, against, or abstain with respect to any matter presented to the Company’s stockholders not addressed by this Agreement.

Section 1.3 Grant of Irrevocable Proxy

Each Stockholder hereby irrevocably appoints Parent and any designee of Parent, and each of them individually, as such Stockholder’s proxy and attorney-in-fact, with full power of substitution and resubstitution, to vote at the Company Stockholders Meeting during the Agreement Term, with respect to such Stockholder’s Owned Shares as of the applicable record date, in each case solely to the extent and in the manner specified in Section 1.1 (the Proxy); provided, however, that such Proxy shall be effective if, and only if, the Stockholder has not delivered to the Secretary of the Company, at least two Business Days prior to the Company Stockholders Meeting, a duly executed proxy card directing that such Stockholder’s Owned Shares be voted in accordance with Section 1.1. The Proxy is given to secure the performance of the duties of each Stockholder under this Agreement, and its existence will not be deemed to relieve any Stockholder of such Stockholder’s obligations under this Agreement. The Proxy shall expire and be deemed revoked automatically at the expiration of the Agreement Term or in the event of termination of this Agreement pursuant to Section 4.1.

2ï13

Section 1.4 Nature of Irrevocable Proxy

The Proxy granted by each Stockholder is irrevocable during the Agreement Term or until this Agreement is terminated pursuant to Section 4.1, shall be deemed to be coupled with an interest sufficient in law to support an irrevocable proxy and shall revoke any and all prior proxies granted by any Stockholder with regard to such Stockholder’s Owned Shares and each Stockholder acknowledges that the Proxy constitutes an inducement for Parent, Merger Sub and Merger Sub LLC to enter into the Merger Agreement. The power of attorney granted by each Stockholder is a durable power of attorney and shall survive the bankruptcy, dissolution, death or incapacity of such Stockholder.

Notwithstanding the foregoing, termination of this Agreement shall not prevent any Party from seeking any remedies (at law or in equity) against any other Party for that Party’s breach of any of the terms of this Agreement prior to the date of termination.

Section 4.3 Entire Agreement; Assignment.

This Agreement (together with the Merger Agreement, to the extent referred to in this Agreement) and any documents delivered by the Parties in connection herewith constitute the entire agreement among the Parties with respect to the subject matter hereof and supersedes all other prior agreements and understandings, both written and oral, among the Parties with respect to the subject matter hereof. Other than as set forth in Section 4.12, nothing in this Agreement, express or implied, is intended to or shall confer upon any person other than the Parties any rights or remedies hereunder. Neither this Agreement nor any of the rights, interests or obligations under this Agreement may be assigned or delegated, in whole or in part, by operation of law or otherwise, by any Party without the prior written consent of the other Parties, and any such assignment without such prior written consent shall be null and void. 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 permitted successors and assigns.

This Agreement may only be amended or waived if, and only if, such amendment or waiver is in writing and signed, in the case of an amendment, by each of the Parties, or in the case of a waiver, by the Party against whom the waiver is to be effective. No failure or delay by Parent, Merger Sub or Merger Sub LLC in exercising any right hereunder shall operate as a waiver thereof nor shall any single or partial exercise thereof preclude any other or further exercise of any other right hereunder.

Section 4.6 Governing Law; Jurisdiction; Waiver of Jury Trial

(a) This Agreement and all Actions (whether based on contract, tort or otherwise) arising out of or relating to this Agreement or the actions of Parent or Merger Sub in the negotiation, administration, performance and enforcement thereof shall be governed by and construed in accordance with the laws of the State of Delaware, regardless of the laws that might otherwise govern under any applicable principles of conflicts of laws thereof.

(b) In any Action between the Parties arising out of or relating to this Agreement or any of the transactions contemplated hereby, each of the Parties (i) irrevocably and unconditionally consents and submits to the exclusive jurisdiction and venue of the Court of Chancery of the State of Delaware in and for New Castle County, Delaware or any federal court sitting in the State of Delaware; (ii) agrees that it will not attempt to deny or defeat such jurisdiction by motion or other request for leave from such court; and (iii) agrees that it will not bring any such action in any court other than the Court of Chancery for the State of Delaware in and for New Castle County, Delaware, or any federal court sitting in the State of Delaware and appellate courts thereof.

8ï13

(c) EACH STOCKHOLDER AND EACH OF PARENT AND MERGER SUB WAIVES, TO THE FULLEST EXTENT PERMITTED BY APPLICABLE LAW, ALL RIGHT TO TRIAL BY JURY IN ANY ACTION, PROCEEDING OR COUNTERCLAIM (WHETHER BASED ON CONTRACT, TORT OR OTHERWISE) ARISING OUT OF OR RELATING TO THIS AGREEMENT.

Section 4.7 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, and that monetary damages, even if available, would not be an adequate remedy therefor. It is accordingly agreed that the Parties shall be entitled to an injunction or injunctions to prevent breaches of this Agreement and to enforce specifically the performance of terms and provisions of this Agreement in any court referred to Section 4.6 above, without proof of actual damages (and each Party hereby waives any requirement for the securing or posting of any bond in connection with such remedy), this being in addition to any other remedy to which they are entitled at law or in equity. The Parties further agree not to assert that a remedy of specific enforcement is unenforceable, invalid, contrary to law or inequitable for any reason, nor to assert that a remedy of monetary damages would provide an adequate remedy for any such breach.

Section 4.8 Counterparts; Effectiveness

This Agreement may be executed in two or more counterparts, all of which shall be considered one and the same agreement and shall become effective when one or more counterparts have been signed by each of the Parties and delivered (including by electronic transmission) to the other Parties.

Section 4.9 Headings

The headings in this Agreement are for reference purposes only and shall not affect in any way the meaning or interpretation of this Agreement.

Section 4.10 Severability

If any term or other provision of this Agreement is held by a court of competent jurisdiction or other authority to be 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 and shall in no way be affected, impaired or invalidated. Upon a 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 to the fullest extent permitted by Applicable Law in a mutually acceptable manner to the end that the Transactions are fulfilled to the fullest extent possible.

9ï13

Section 4.11 Interpretation

When a reference is made in this Agreement to an Article, Section or Exhibit, such reference shall be to an Article or Section of, or an Exhibit to, this Agreement, unless otherwise indicated. Whenever the words “include,” “includes” or “including” are used in this Agreement, they shall be deemed to be followed by the words “without limitation.” The words “hereof,” “hereto,” “hereby,” “herein” and “hereunder” and words of similar import when used in this Agreement shall refer to this Agreement as a whole and not to any particular provision of this Agreement. The term “or” is not exclusive. The word “extent” in the phrase “to the extent” shall mean the degree to which a subject or other thing extends, and such phrase shall not mean simply “if.” All terms defined in this Agreement shall have the defined meanings when used in any certificate or other document made or delivered pursuant hereto unless otherwise defined therein. The definitions contained in this Agreement are applicable to the singular as well as the plural forms of such terms and to the masculine as well as to the feminine and neuter genders of such term. Any agreement, instrument or statute defined or referred to herein or in any agreement or instrument that is referred to herein means such agreement, instrument or statute as from time to time amended, modified or supplemented, unless otherwise specifically indicated. References to a person are also to its permitted successors and assigns. Unless otherwise specifically indicated, all references to dollars and $ will be deemed references to the lawful money of the United States of America.
