DEFINITIONS

Section 1.1    Defined Terms. The following terms, as used in this Agreement, shall have the meanings specified in this Section 1.1. Capitalized terms used but not otherwise defined herein shall have the meanings ascribed thereto in the Merger Agreement.

“Beneficial Owner” shall have the meaning given to such term in Rule 13d-3 under the Exchange Act (without giving effect to the limiting phrase “within sixty days” set forth in Rule 13d-3(d)(1)(i)); provided, that Parent shall not be deemed to be the Beneficial Owner of the Covered Company Shares by virtue of this Agreement. The terms “Beneficially Own,” “Beneficially Owned” and “Beneficial Ownership” shall have a correlative meaning.

“Covered Company Shares” means, with respect to Stockholder, (1) Stockholder’s Existing Shares and (2) any shares of Company Common Stock or other voting capital stock of the Company and any Securities convertible into or exercisable or exchangeable for shares of Company Common Stock or other voting capital stock of the Company, in each case that Stockholder has Beneficial Ownership of on or after the date hereof; it being understood that if Stockholder acquires Securities (or rights with respect thereto) described in clause (2) above (to the extent such Securities are not timely reported, or required to be reported, in a filing by Stockholder with the SEC), Stockholder shall promptly notify Parent in writing, indicating the number of such Securities so acquired.

“Permitted Transfer” means a Transfer of Covered Company Shares by Stockholder (a) in connection with the exercise, vesting or settlement of Company Equity Awards (including the net settlement of such equity or sale of underlying shares of Company Common Stock in order to pay any exercise price and any tax withholding obligations in connection therewith), (b) to any Affiliate of Stockholder, (c) if Stockholder is an individual, (i) to any member of Stockholder’s immediate family or to a trust for the benefit of Stockholder or any member of Stockholder’s immediate family or (ii) to any person or entity if and to the extent required by any non-consensual legal order, by divorce decree or by will, intestacy or other similar law or (d) if Stockholder is a director or officer of the Company set forth on Schedule IV hereto, a Transfer up to the number of Covered Company Shares set forth on Schedule IV pursuant to a written trading plan of the Company in effect on the date hereof and that is intended to satisfy the requirements of Rule 10b5-1 under the Exchange Act; provided, however, that in the case of the foregoing clauses (b) or (c)(i), any such Transfer shall only be a Permitted Transfer if and to the extent that the transferee of such Covered Company Shares evidences in a writing in form and substance reasonably satisfactory to Parent such transferee’s agreement to be bound by and subject to the terms and provisions hereof to the same effect as the transferring Stockholder, and upon such transfer to be deemed a Stockholder hereunder.

“Transfer” means any direct or indirect sale, assignment, encumbrance, pledge, hypothecation, disposition or other transfer (by operation of law or otherwise), either voluntary or involuntary, or entry into any contract, option or other arrangement or understanding with respect to any sale, assignment, encumbrance, pledge, hypothecation, disposition or other transfer (by operation of law or otherwise), of any capital stock or interest (including voting interest) in any capital stock (including any Covered Company Shares).

2

each case to the extent that the Covered Company Shares are entitled to vote thereon or consent thereto:

(i)    appear at each such meeting or otherwise cause all of Stockholder’s Covered Company Shares to be counted as present thereat for purposes of calculating a quorum; and

(ii)    vote (or cause to be voted), in person or by proxy, or if applicable deliver (or cause to be delivered) a written consent covering, all of Stockholder’s Covered Company Shares:

(b)    Any vote required to be cast or consent required to be executed pursuant to this Section 2.1 shall be cast or executed in accordance with the applicable procedures relating thereto so as to ensure that it is duly counted for purposes of determining that a quorum is present (if applicable) and for purposes of recording the results of that vote or consent. Nothing contained in this Agreement shall require Stockholder (or shall entitle any proxy of Stockholder) to convert, exercise or exchange any option, warrants or convertible securities in order to obtain any underlying shares of Company Common Stock.

Section 2.2    No Inconsistent Agreements. Stockholder represents, covenants and agrees that, except for this Agreement, Stockholder (a) has not entered into, nor shall enter into at any time while this Agreement remains in effect, any voting agreement, voting trust or similar

The proxy granted by Stockholder hereunder shall be irrevocable during the Voting Period, shall be deemed to be coupled with an interest sufficient in Law to support an irrevocable proxy, and Stockholder (a) will take such further action or execute such other instruments as may be necessary to effectuate the intent of this proxy and (b) hereby revokes any proxy previously granted by Stockholder with respect to any Covered Company Shares (other than Routine Matters, as defined below). The power of attorney granted by Stockholder hereunder is a durable power of attorney and shall survive the bankruptcy, death or dissolution of Stockholder. Other than (i) as provided in this Section 2.3, (ii) the granting of proxies to vote Covered Company Shares to an Affiliate of Stockholder as a Permitted Transfer and (iii) the granting of proxies to vote Covered Company Shares with respect to the election of directors, ratification of the appointment of the Company’s auditors at the Company’s annual meeting or special meeting of stockholders, and other routine matters at the Company’s annual meeting or any special meeting, in either case, to the extent such matters are not (x) inconsistent with the obligations contemplated by the Merger Agreement or this Agreement or (y) related to the transactions contemplated by the Merger Agreement or this Agreement (collectively, “Routine Matters”), Stockholder shall not directly or indirectly grant any Person any proxy (revocable or irrevocable), power of attorney or other authorization with respect to the voting of any of Stockholder’s Covered Company Shares. Parent may terminate this proxy with respect to Stockholder at any time at its sole election by written notice provided to Stockholder.

Section 3.1    Restrictions on Transfers. Stockholder hereby agrees that, during the Voting Period, (i) Stockholder shall not, directly or indirectly, Transfer or consent to a Transfer of any Covered Company Shares or any Beneficial Ownership interest or any other interest therein, unless such Transfer is a Permitted Transfer and (ii) any Transfer in violation of this provision shall be void.

Section 3.2    No Solicitation. During the Voting Period, (i) Stockholder shall, and Stockholder shall cause each of his, her or its controlled Affiliates and its and their Representatives to, immediately cease and cause to be terminated all existing activities, discussions, negotiations and communications, if any, with any Persons (or any of their Representatives) with respect to a Company Acquisition Proposal (other than Parent or any of its Affiliates or Representatives with respect to the transactions contemplated by the Merger Agreement), (ii) Stockholder shall not, and Stockholder shall cause each of his, her or its controlled Affiliates and his, her or its and their Representatives to not, directly or indirectly, (a) initiate, seek, solicit, facilitate or knowingly encourage, or induce or take any other action designed or intended to lead to, or that would reasonably be expected to lead to any inquiry with respect to, or the making, submission or announcement of, any Company Acquisition Proposal, (b) enter into, continue or otherwise participate in any negotiations or discussions with, or furnish or cause to be furnished any information or data to, or cause to be furnished access to the Company’s (of any of its Subsidiaries’) properties with respect to, or otherwise cooperate in any way with, any Person (other than Parent or any of its Affiliates or Representatives) relating to any Company Acquisition Proposal or any proposal reasonably expected to lead to any Company Acquisition Proposal, (c) enter into any letter of intent, memorandum of understanding, merger agreement or other agreement, arrangement or understanding relating to any Company Acquisition Proposal, (d) submit or cause to be submitted to the stockholders of the Company for their approval any Company Acquisition Proposal or (e) agree or announce an intention to do any of the foregoing and (iii) Stockholder shall, and Stockholder shall cause each of his, her or its controlled Affiliates and his, her or its and their Representatives to, use their respective reasonable best efforts to cause any such third Person (and its Representatives) in possession of confidential information about the Company or any of its Subsidiaries (or its or its Subsidiaries’ businesses or operations) to return or destroy all such information or any other confidential information that has been provided in any such discussions or negotiations relating to a possible Company Acquisition Proposal.

The Parties hereto agree that irreparable damage for which monetary damages, even if available, would not be an adequate remedy, would occur in the event that any Party hereto does not perform the provisions of this Agreement (including failing to take such actions as are required of it hereunder to consummate this Agreement) in accordance with its specified terms or otherwise breach such provisions. Accordingly, the Parties hereto acknowledge and agree that, prior to any termination of this Agreement in accordance with Section 5.1, in the event of any breach or threatened breach by Parent, on the one hand, or Stockholder, on the other hand, of any of their respective covenants or obligations set forth in this Agreement, Parent, on the one hand, and Stockholder, on the other hand, shall be entitled to

an injunction, specific performance and other equitable relief to prevent breaches of this Agreement and to enforce specifically the terms and provisions hereof, in addition to any other remedy to which they are entitled at law or in equity. Each of the Parties hereto agrees that it will not oppose the granting of an injunction, specific performance and other equitable relief on the basis that any other Party has an adequate remedy at law or that any award of specific performance is not an appropriate remedy for any reason at law or in equity. Any Party hereto seeking an injunction or injunctions to prevent breaches of this Agreement and to enforce specifically the terms and provisions of this Agreement shall not be required to provide any bond or other security in connection with any such order or injunction.    

Section 6.13    Consent to Jurisdiction.

(a)    Each of the Parties hereto hereby, with respect to any legal claim or Proceeding arising out of this Agreement or the transactions contemplated by this Agreement, (i) expressly and irrevocably submits, for itself and with respect to its property, generally and unconditionally, to the exclusive jurisdiction of the Delaware Court of Chancery and any appellate court therefrom within the State of Delaware (or, if the Delaware Court of Chancery declines to accept jurisdiction over a particular matter, any state or federal court within the State of Delaware), (ii) agrees that it will not attempt to deny or defeat such personal jurisdiction by motion or other request for leave from any such courts, (iii) agrees that it will not bring any claim or Proceeding relating to this Agreement or the transactions contemplated by this Agreement except in such courts and (iv) irrevocably waives, to the fullest extent it may legally and effectively do so, and agrees not to assert, by way of motion or as a defense, counterclaim or otherwise, any objection which it may now or hereafter have to the laying of venue of any claim or Proceeding arising out of or relating to this Agreement. Notwithstanding the foregoing, each of Parent and Stockholder agrees that a final and nonappealable judgment in any Proceeding shall be conclusive and may be enforced in other jurisdictions by suit on the judgment or in any other manner provided by Law.

(b)    Each Party hereto irrevocably consents to the service of process in any claim or Proceeding with respect to this Agreement and the transactions contemplated by this Agreement or for recognition and enforcement of any judgment in respect hereof brought by any other Party hereto may be made by mailing copies thereof by registered or certified United States mail, postage prepaid, return receipt requested, to its address as specified in or pursuant to Section 6.5 and such service of process shall be sufficient to confer personal jurisdiction over such party in such claim or Proceeding and shall otherwise constitute effective and binding service in every respect.

Section 6.14    WAIVER OF JURY TRIAL. EACH OF THE PARTIES HERETO HEREBY IRREVOCABLY WAIVES ALL RIGHT TO TRIAL BY JURY IN ANY ACTION, PROCEEDING OR COUNTERCLAIM (WHETHER BASED ON CONTRACT, TORT OR OTHERWISE) BETWEEN ANY OF THEM ARISING OUT OF OR RELATING TO THIS AGREEMENT OR THE ACTIONS OF ANY PARTY IN THE NEGOTIATION, ADMINISTRATION, PERFORMANCE AND ENFORCEMENT THEREOF.
