WHEREAS, as a condition to Parent’s willingness to enter into and perform its obligations under the Merger Agreement, Parent has required that each Stockholder agree, and each Stockholder has agreed, to enter into this Agreement.

NOW, THEREFORE, in consideration of the premises and for other good and valuable consideration given to each party hereto, the receipt of which is hereby acknowledged, the parties agree as follows:

1.                                      Agreement to Vote.

1.1                               Agreement to Vote.  Each Stockholder hereby irrevocably and unconditionally agrees that, from the date hereof 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 5.1 (the “Agreement Term”), at any meeting of the stockholders of the Company at which the approval and adoption of the Merger Agreement and the transactions contemplated thereby is to be voted upon, however called, or any adjournment or postponement thereof, such Stockholder shall be present (in person or by proxy) and vote (or cause to be voted), to the extent entitled to vote thereon, all of its Owned Shares at such time: (i) in favor of (A) approval and adoption of the Merger Agreement and the transactions contemplated thereby, including the Merger and (B) the approval of any proposal to adjourn or postpone the meeting to a later date if there are not sufficient votes for adoption of the Merger Agreement; and (ii) against (V) any Alternative Proposal, (W) any extraordinary dividend or distribution by the Company, (X) any material change in the capital structure of the Company or any Subsidiary of the Company, (Y) any merger agreement or merger (other than the Merger Agreement), consolidation, combination, material business transaction, sale of assets, reorganization, recapitalization, dissolution, liquidation or winding up of the Company, or any other action or transaction involving the Company, and (Z) any amendment of the Company’s organizational documents that, in the case of (W), (X), (Y) or (Z), would or would reasonably be expected to materially impair the ability of Parent or Merger Sub to complete the Merger, or that would or would reasonably be expected to prevent, materially impede or materially delay the consummation of the Merger.

Anything herein to the contrary notwithstanding, this Section 1.1 shall not require any Stockholder to be present (in person or by proxy) or vote (or cause to be voted) any of its Owned Shares to amend the Merger Agreement or take any action that results or could result in the amendment or modification, or a waiver of a provision therein, in any such case, in a manner that (i) decreases the amount or changes the form of the Merger Consideration or (ii) imposes any material restrictions on or additional conditions on the payment of the Merger Consideration to stockholders.

1.2                               Other Voting Rights.  Except as permitted by this Agreement, throughout the Agreement Term, each Stockholder will continue to hold and shall have the right to exercise all voting rights related to such Stockholder’s Owned Shares.  For the avoidance of doubt, except as expressly set forth in Section 1.1, nothing in this Agreement shall limit the right of each Stockholder to vote in favor of, against, or abstain with respect to any matter presented to the Company’s stockholders not addressed by Section 1.1.

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 any annual or special meeting of stockholders at which any of the matters described in Section 1.1. is to be considered during the Agreement Term, with respect to the Owned Shares as of the applicable record date, in each case solely to the extent and in the manner specified in Section 1.1; provided, however, that such Stockholder’s grant of the proxy contemplated by this Section 1.3 shall be effective if, and only if, such Stockholder has not delivered to the Secretary of the Company, at least two Business Days prior to the applicable meeting, a duly executed irrevocable proxy card directing that the Owned Shares be voted in accordance with Section 1.1. This proxy, if it becomes effective, is given to secure the performance of the duties of such Stockholder under this Agreement, and its existence will not be deemed to relieve such Stockholder of its obligations under Section 1.1.  This proxy shall expire and be deemed revoked automatically at the expiration of the Agreement Term.

2.                                      Representations and Warranties of Stockholders.  Each Stockholder hereby represents and warrants to Parent as of the date of this Agreement and as of the Company Meeting as follows:

2.3                               No Conflict.

5.6                               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, without giving effect to any choice or conflict of law provision or rule (whether of the State of Delaware or any other jurisdiction) that would cause the application of the laws of any jurisdiction other than the State of Delaware.  In addition, each of the parties hereto irrevocably agrees that any legal action or proceeding with respect to this Agreement and the rights and obligations arising hereunder, or for recognition and enforcement of any judgment in respect of this Agreement and the rights and obligations arising hereunder brought by the other party hereto or its successors or assigns, shall be brought and determined exclusively in the Delaware Court of Chancery and any state 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).  Each of the parties hereto hereby irrevocably submits with regard to any such action or proceeding for itself and in respect of its property, generally and unconditionally, to the personal jurisdiction of the aforesaid courts and agrees that it will not bring any action relating to this Agreement or any of the transactions contemplated by this Agreement in any court other than the aforesaid courts.

7

Each of the parties hereto hereby irrevocably waives, and agrees not to assert as a defense, counterclaim or otherwise, in any action or proceeding with respect to this Agreement, (i) any claim that it is not personally subject to the jurisdiction of the above named courts for any reason other than the failure to serve in accordance with this Section 5.6, (ii) any claim that it or its property is exempt or immune from the jurisdiction of any such court or from any legal process commenced in such courts (whether through service of notice, attachment prior to judgment, attachment in aid of execution of judgment, execution of judgment or otherwise) and (iii) to the fullest extent permitted by the applicable Law, any claim that (x) the suit, action or proceeding in such court is brought in an inconvenient forum, (y) the venue of such suit, action or proceeding is improper or (z) this Agreement, or the subject matter hereof, may not be enforced in or by such courts.

(b)                                 WITHOUT LIMITING SECTION 5.6(A), EACH OF THE PARTIES TO THIS AGREEMENT HEREBY IRREVOCABLY WAIVES ANY AND ALL RIGHT TO A TRIAL BY JURY IN ANY ACTION, PROCEEDING OR COUNTERCLAIM ARISING OUT OF OR RELATING TO THIS AGREEMENT, THE TRANSACTIONS CONTEMPLATED HEREBY, THE MERGER AGREEMENT OR THE TRANSACTIONS CONTEMPLATED THEREBY.  EACH PARTY MAKES THIS WAIVER VOLUNTARILY AND SUCH PARTY HAS BEEN INDUCED TO ENTER INTO THIS AGREEMENT BY, AMONG OTHER THINGS, THE MUTUAL WAIVERS CONTAINED IN THIS SECTION 5.6(B).

5.7                               Specific Performance; Exclusive Remedy.

(a)                                 The parties 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.  Each party agrees that in the event of any breach or threatened breach by any other party of any covenant or obligation contained in this Agreement, the non-breaching party shall be entitled (in addition to any other remedy that may be available to it whether in law or equity, including monetary damages) to seek to obtain (i) a decree or order of specific performance to enforce the observance and performance of such covenant or obligation, and (ii) an injunction restraining such breach or threatened breach.

(b)                                 Each party further agrees that (x) it will not oppose the granting of an injunction, specific performance and other equitable relief as provided herein on the basis that the other party has an adequate remedy at law or an award of specific performance is not an appropriate remedy for any reason at law or equity and (y) no other party or any other Person shall be required to obtain, furnish or post any bond or similar instrument in connection with or as a condition to obtaining any remedy referred to in this Section 5.7, and each party irrevocably waives any right it may have to require the obtaining, furnishing or posting of any such bond or similar instrument.  Anything in this Agreement to the contrary notwithstanding, Parent hereby agrees that specific performance or injunctive relief pursuant to this Section 5.7 shall be its sole and exclusive remedy with respect to breaches or threatened breaches by any Stockholder in connection with this Agreement, and neither Parent nor any of its Affiliates may pursue or accept any other form of relief (including monetary damages) that may be available for breach of this Agreement

5.8                               Counterparts; Effectiveness.  This Agreement may be executed in two or more consecutive counterparts (including by facsimile), each of which shall be an original, with the same effect as if the signatures thereto and hereto were upon the same instrument, and shall become effective when one or more counterparts have been signed by each of the parties and delivered (by telecopy or otherwise) to the other parties.

8

5.9                               Headings.  Headings of the Articles and Sections of this Agreement are for convenience of the parties only and shall be given no substantive or interpretive effect whatsoever.

5.10                        Severability.  Any term or provision of this Agreement which is invalid or unenforceable in any jurisdiction shall, as to that jurisdiction, be ineffective to the sole extent of such invalidity or unenforceability without rendering invalid or unenforceable the remainder of such term or provision or the remaining terms and provisions of this Agreement in any jurisdiction.  If any provision of this Agreement is so broad as to be unenforceable, such provision shall be interpreted to be only so broad as is enforceable.

5.11                        Non-Recourse.

(a)                                 Anything that may be expressed or implied in this Agreement notwithstanding, each of the parties hereto covenants, acknowledges and agrees that no person other than the parties to this Agreement shall have any liability or obligation hereunder and that, (i) the fact that any Affiliate of any of the parties to this Agreement may be a partnership or limited liability company notwithstanding, no recourse hereunder or under any documents or instruments delivered in connection herewith shall be had against any former, current or future direct or indirect director, officer, employee, agent, partner, manager, member, securityholder, Affiliate, stockholder, controlling Person, assignee or representative of the parties hereto under this Agreement or under the Merger Agreement (any such person or entity, other than the parties to this Agreement, or their assignees under this Agreement or the Merger Agreement, a “Related Party”) or any Related Party of any of such parties’ Related Parties (including, without limitation, in respect of any liabilities or obligations arising under, or in connection with, any claim, including, without limitation, any claim of breach of a party’s obligations under the Merger Agreement and the transactions contemplated thereby or under this Agreement and the transactions contemplated hereby) whether by the enforcement of any judgment or assessment or by any legal or equitable proceeding, or by virtue of any statute, regulation or other applicable Law, and (ii) no personal liability whatsoever will attach to, be imposed on or otherwise incurred by any Related Party of any of the parties to this Agreement or any Related Party of any of such parties’ Related Parties under this Agreement or for any claim based on, in respect of, or by reason of the transactions contemplated hereby or contemplated by the Merger Agreement, or by the creation of such transactions.  Nothing in this Agreement, express or implied, is intended to or shall confer upon any person, other than the parties to this Agreement, any right, benefit or remedy of any nature whatsoever under or by reason of this Agreement.

5.12                        Interpretation.  When a reference is made in this Agreement to an Article or Section, such reference shall be to an Article or Section of 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,” “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.  All terms defined in this Agreement shall have the defined meanings when used in any certificate or other document made or delivered pursuant thereto 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 terms.

9

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, including (in the case of agreements or instruments) by waiver or consent and (in the case of statutes) by succession of comparable successor statutes and references to all attachments thereto and instruments incorporated therein.  Each of the parties has participated in the drafting and negotiation of this Agreement.  If an ambiguity or question of intent or interpretation arises, this Agreement must be construed as if it is drafted by all the parties, and no presumption or burden of proof shall arise favoring or disfavoring any party by virtue of authorship of any of the provisions of this Agreement.
