(a)                                  Prior to  the Acceptance Time, Parent shall deposit or cause to be deposited with a bank or trust company selected by Parent and reasonably acceptable to the Company (the “ Paying Agent ”) cash in an amount sufficient to pay the aggregate Offer Price (calculated for purposes of this Section 3.4(a)  assuming that all outstanding Shares are tendered

into the Offer), and Parent shall cause the Paying Agent to timely make all payments contemplated in Section 3.4(b) .  Such cash may be invested by the Paying Agent as directed by Parent; provided (i) that such investments must be in short-term obligations of the United States of America with maturities of no more than thirty (30) days or guaranteed by the United States of America and backed by the full faith and credit of the United States of America or in commercial paper obligations rated A-1 or P-1 or better by Xxxxx’x Investors Service, Inc. or Standard & Poor’s Corporation, respectively, (ii) no such investment will relieve Parent, Purchaser, or the Paying Agent from making the payments required by this ARTICLE III and (iii) no such investment will have maturities that could prevent or delay payments to be made pursuant to this Agreement.  Any interest or income produced by such investments will be payable to the Surviving Corporation or Parent, as Parent directs.  No loss incurred with respect to such investments will decrease the amounts payable pursuant to this Agreement.  In the event that the amount of cash held by the Paying Agent is insufficient to pay the aggregate Offer Price and Merger Consideration, Parent shall deposit, or cause to be deposited, additional funds with the Paying Agent to ensure the prompt payment of the Offer Price and Merger Consideration.  The cash as so deposited with the Paying Agent will not be used for any purpose other than to fund payments pursuant to Section 3.4(b) , except as expressly provided for in this Agreement.  Any portion of the cash made available to the Paying Agent in respect of any Dissenting Shares will be returned to Parent.

(b)                                  As promptly as reasonably practicable after the Effective Time (and in any event within three (3) Business Days thereafter), Parent shall cause the Paying Agent to mail to each holder of record of a certificate (a “ Certificate ”) or a book-entry share (“ Book-Entry Share ”), which immediately prior to the Effective Time represented outstanding Shares that were converted pursuant to Section 3.1(a)  into the right to receive the Merger Consideration, (i) a letter of transmittal in customary form (which shall specify that delivery shall be effected, and risk of loss and title to the Certificate shall pass, only upon delivery of such Certificate to the Paying Agent and customary provisions regarding delivery of an “agent’s message” with respect to Book-Entry Shares) and (ii) instructions for effecting the surrender of the Certificate or Book-Entry Share in exchange for payment of the Merger Consideration.  Upon surrender of a Certificate or Book-Entry Share for cancellation to the Paying Agent or to such other agent or agents as may be appointed by Parent, together with such letter of transmittal, duly executed and properly completed, or “agent’s message”, as applicable, and such other documents as may be reasonably required by the Paying Agent, the holder of such Certificate or Book-Entry Share will be entitled to receive in exchange therefor the Merger Consideration as provided in Section 3.1(a)  for each Share formerly represented by such Certificate or Book-Entry Share, and the Certificate or Book-Entry Share so surrendered will be cancelled.  Until surrendered as contemplated by this Section 3.4(b) , each Certificate or Book-Entry Share shall be deemed at any time after the Effective Time to represent only the right to receive the Merger Consideration as provided in Section 3.1(a)  and will not evidence any interest in, or any right to exercise the rights of a stockholder or other equity holder of, the Company or the Surviving Corporation.  No interest shall be paid or accrue on the cash payable upon the surrender of any Certificate or Book-Entry Share.

(c)                                   At any time following the date that is six (6) months after the Effective Time, Parent may require the Paying Agent to deliver to Parent any funds (including any interest received with respect thereto) that have been made available to the Paying Agent and that have

Section 3.6.                                  Withholding .  Each of Parent, Purchaser, the Surviving Corporation and the Paying Agent is entitled to deduct and withhold from any amounts payable or otherwise deliverable pursuant to this Agreement to any holder or former holder of Shares or Company Equity Awards such amounts as are required to be deducted and withheld therefrom under the United States Internal Revenue Code of 1986, as amended (the “ Code ”), or the Treasury Regulations thereunder, or any other Tax Law.  Any compensatory amounts payable pursuant to or as contemplated by this Agreement, including pursuant to Section 3.2 , will be remitted to the applicable payor for payment to the applicable Person through regular payroll procedures, as

applicable.  To the extent that any amounts are so deducted and withheld, such amounts will be treated for all purposes under this Agreement as having been paid to the Person to whom such amounts would otherwise have been paid.

Section 3.7.                                  Transfer Taxes .  If any payment pursuant to the Offer or the Merger is to be made to a Person other than the Person in whose name the surrendered Certificate or Book-Entry Share is registered, it will be a condition to such payment that (i) such Certificate or Book-Entry Share so surrendered must be properly endorsed or must otherwise be in proper form and (ii) the Person presenting such Certificate or Book-Entry Share to the Paying Agent for payment must pay to the Paying Agent any transfer or other Taxes required as a result of such payment to a Person other than the registered holder of such Certificate or Book-Entry Share or must establish to the satisfaction of the Paying Agent that such Tax has been paid or is not required to be paid.  Parent shall pay any other transfer Taxes.

Section 9.5.                                  Entire Agreement; Third-Party Beneficiaries .  This Agreement (including the Company Disclosure Letter and the exhibits, annexes, schedules and instruments referred to herein), the Confidentiality Agreement and the Tender and Support Agreements constitute the

entire agreement and supersede all prior agreements and understandings, both written and oral, among the Parties and their Affiliates, or any of them, with respect to the subject matter hereof or thereof; provided , however , that the Confidentiality Agreement (a) will survive the execution or termination of this Agreement and remains in full force and effect and (b) will terminate as of the Effective Time. Except as provided in Section 6.5 (which is intended for the benefit of the Company’s former and current officers and directors, all of whom will be third-party beneficiaries of these provisions), this Agreement is not intended to confer upon any Person other than the Parties any rights or remedies.  Notwithstanding the immediately preceding sentence, following the Effective Time the provisions of ARTICLE II shall be enforceable by holders of Certificates and holders of Book-Entry Shares solely to the extent necessary to receive the Merger Consideration to which such holders are entitled to thereunder.

Section 9.6.                                  Governing Law .  This Agreement will be governed by, and construed in accordance with, the Laws of the State of Delaware , regardless of the Laws that might otherwise govern under applicable principles of conflicts of laws thereof.

Section 9.8.                                  Counterparts .  This Agreement may be executed and delivered (including by facsimile or email transmission) in one (1) or more counterparts, and by the different Parties in separate counterparts, each of which when executed will become effective and be deemed to be an original but all of which taken together will constitute one and the same agreement.

Section 9.9.                                  Jurisdiction; Waiver of Jury Trial .

(a)                                  Each of the Parties hereby (i) expressly and irrevocably submits to the exclusive personal jurisdiction of the Court of Chancery of the State of Delaware or if such Court of Chancery lacks subject matter jurisdiction, the United States District Court for the District of Delaware , in the event any dispute arises out of this Agreement, the Offer, the Merger or the actions of Parent, Purchaser or the Company in the negotiation, administration, performance and enforcement in connection with this Agreement, (ii) agrees that it shall not attempt to deny or defeat such personal jurisdiction by motion or other request for leave from any such court, and (iii) agrees that it shall not bring any action relating to this Agreement, the Offer, or the Merger in any court other than the Court of Chancery of the State of Delaware or if such Court of Chancery lacks subject matter jurisdiction, the United States District Court for the District of Delaware; provided that each of the Parties has the right to bring any action or proceeding for enforcement of a judgment entered by such court in any other court or jurisdiction.  The Parties agree that a final trial court judgment in any such Proceeding shall be conclusive and may be enforced in other jurisdiction by suit on the judgment or in any manner provided by Law; provided that nothing in the foregoing shall restrict any Party’s right to seek any post-judgment relief regarding, or any appeal from, such final trial court judgment.

(b)                                  EACH PARTY ACKNOWLEDGES AND AGREES THAT ANY CONTROVERSY WHICH MAY ARISE UNDER THIS AGREEMENT IS LIKELY TO INVOLVE COMPLICATED AND DIFFICULT ISSUES, AND THEREFORE SUCH PARTY

HEREBY IRREVOCABLY AND UNCONDITIONALLY WAIVES ANY RIGHT IT MAY HAVE TO A TRIAL BY JURY IN ANY LITIGATION ARISING OUT OF, RELATING TO OR IN CONNECTION WITH THIS AGREEMENT.  EACH PARTY CERTIFIES AND ACKNOWLEDGES THAT (I) NO REPRESENTATIVE, AGENT, OR ATTORNEY OF ANY PARTY HAS REPRESENTED, EXPRESSLY OR OTHERWISE, THAT SUCH PARTY WOULD NOT, IN THE EVENT OF LITIGATION, SEEK TO ENFORCE THE FOREGOING WAIVER, (II) EACH PARTY UNDERSTANDS AND HAS CONSIDERED THE IMPLICATION OF THIS WAIVER, (III) EACH PARTY MAKES THIS WAIVER VOLUNTARILY, AND (IV) EACH OTHER PARTY HAS BEEN INDUCED TO ENTER INTO THIS AGREEMENT BY, AMONG OTHER THINGS, THE MUTUAL WAIVERS AND CERTIFICATIONS IN THIS SECTION.

Section 9.10.                           Service of Process .  Each Party irrevocably consents to the service of process relating to this Agreement, the Offer, the Merger or any of the transactions contemplated by this Agreement, on behalf of itself or its property, outside the territorial jurisdiction of the courts referred to in Section 9.9(a)  in any such action or proceeding by mailing copies thereof by registered United States mail, postage prepaid, return receipt requested, to its address as specified in or pursuant to Section 9.2 .  However, the foregoing will not limit the right of a Party to effect service of process on the other Party by any other legally available method.

Section 9.11.                           Specific Performance .

(a)                                  The Parties acknowledge and agree that, in the event of any breach of this Agreement, irreparable harm would occur and that monetary damages, even if available, would not be an adequate remedy therefor.  It is accordingly agreed that (i) each Party shall be entitled, in addition to any other remedy to which it may be entitled at law or in equity, to an injunction or any other appropriate form of equitable relief, to compel specific performance and to prevent or restrain breaches or threatened breaches of this Agreement in any action without the posting of a bond or undertaking in connection with such remedy, and (ii) the Parties shall, and hereby do, waive, in any action for specific performance, the defense of adequacy of a remedy at law and any other objections to specific performance of this Agreement.

(b)                                  Notwithstanding the Parties’ rights to specific performance pursuant to Section 9.11(a) , each Party may pursue any other remedy available to it at law or in equity, including monetary damages; provided that it is understood and agreed that claims for monetary damages following termination of this Agreement shall be (i) limited to those arising from or relating to Fraud or any Willful Breach of this Agreement prior to such termination and (ii) subject to Section 8.5(a) .  Notwithstanding anything in this Agreement to the contrary, prior to the termination of this Agreement in accordance with its terms, no Party is permitted to make any claim or commence any Proceeding seeking monetary damages against any other Party in connection with or arising out of this Agreement, the Offer, or the Merger; provided that the foregoing is without prejudice to the right of any Party to seek such monetary damages following such termination in accordance with, and subject to the limitations set forth in, this Agreement.
