(b) Initiate or participate in, knowingly encourage or take any other action (or permit its Representatives to do any of the foregoing) that may facilitate, any inquiries or the making of any proposal or offer that constitutes, or may reasonably be expected to lead to, any Takeover Proposal, or enter into, continue or otherwise participate in any discussions or negotiations regarding, furnish to any Person any information with respect to, assist or participate in any effort or attempt by any Person with respect to, or otherwise cooperate in any way with, any Takeover Proposal; or

(c) take any action, or omit to take any action which may be taken without more than immaterial expense, that would restrict, limit or interfere with his or her obligations hereunder.

3. Limitations; Termination. Sections 1 and 2 shall not be binding upon Stockholder if the Merger Agreement is amended to materially decrease the Merger Consideration or change the form thereof. This Agreement shall automatically terminate upon the termination of the Merger Agreement in accordance with its terms; provided, that nothing in this Agreement shall relieve any party from liability for any fraud or willful breach by it of this Agreement prior to the effectiveness of such termination.

5. Miscellaneous.

(a) This Agreement is governed by and shall be construed in accordance with the laws of the State of Delaware applicable to agreements made and to be performed entirely within such State, without regard to any conflicts of law principles that would require the application of any other Law. THE PARTIES HEREBY WAIVE ANY RIGHT TO TRIAL BY JURY IN ANY LEGAL ACTION ARISING OUT OF OR RELATING TO THIS

AGREEMENT. Each of the parties irrevocably consents to submit itself to the jurisdiction of the United States District Court for Delaware (and if such court shall decline to accept jurisdiction over any particular matter, the Supreme Court of the State of Delaware located in the County of Wilmington) in the event any dispute or Legal Action arises out of or relates to this Agreement.

(b) The parties hereto 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 by Stockholder. It is accordingly agreed that Parent shall be entitled to an injunction or injunctions to prevent breaches of this Agreement and to specifically enforce this Agreement.

(c) All notices or other communications required or permitted to be given hereunder shall be in writing and shall be deemed given to a party when (i) delivered by hand or by a nationally recognized overnight courier service (costs prepaid) or (ii) sent by registered or certified mail, postage prepaid, return receipt requested, in each case to the following: (A) if to Parent or Merger Sub, to the address set forth in the Merger Agreement, and (B) if to Stockholder, to the address set forth on the signature page hereto.

(d) This Agreement and the rights and obligations hereunder shall not be assignable or transferable by any party (including, by operation of Law or in connection with a merger or sale of substantially all the assets, stock or membership interests of such party) without the prior written consent of the other parties hereto; provided, that Parent may assign all or any of its rights and obligations hereunder to an Affiliate without any need to obtain consent. This Agreement may not be amended except by an instrument in writing signed by each party hereto. This Agreement contains the entire agreement and understanding among the parties with respect to the subject matter hereof and supersedes all prior oral and written agreements and understandings relating to such subject matter. Whether or not the Merger or any other transaction contemplated by the Merger Agreement is consummated, each party will bear its respective fees, costs and expenses incurred in connection with the preparation, negotiation, execution and performance of this Agreement. This Agreement may be executed in counterparts, each of which shall be considered one and the same agreement, and shall become effective when all such counterparts have been signed by each of the parties and delivered to the other parties.

(e) If any provision of this Agreement or the application of any such provision to any Person or circumstance shall be held invalid, illegal or unenforceable in any respect by a court of competent jurisdiction, such invalidity, illegality or unenforceability shall not affect any other provision hereof and all other conditions and provisions of this Agreement shall nevertheless remain in full force and effect.

(f) Stockholder is not making any agreement or understanding herein in his or her capacity as a director or officer of the Company. Stockholder signs solely in his or her capacity as the beneficial owner of the Shares and nothing herein shall limit or affect any actions taken by Stockholder in his or her capacity as an officer or director of the Company to the extent permitted by the Merger Agreement.

IN WITNESS WHEREOF, the parties have executed this Voting Agreement as of the date first written above.
