Any such claim for indemnification shall be satisfied first from any then available portion of the remaining Company Equityholder Representative Expense Amount and, if such amount is insufficient to satisfy any such Representative Reimbursable Expense, from the first proceeds from any Future Payments otherwise available for distribution to the Company Equityholders. Without limiting the foregoing, the Company Equityholder Representative shall have the right to engage legal counsel and other professional advisers to assist it in the administration of Company Equityholder Representative’s duties hereunder, and any and all reasonable fees and expenses of such counsel and advisers shall be deemed Representative Reimbursable Expenses.  In no event shall the Buyer or the Surviving Corporation (or any of their respective Affiliates) be obligated to reimburse the Company Equityholder Representative for any costs or expenses of the Company Equityholder Representative, whether or not such costs or expenses constitute Representative Reimbursable Expenses.

1.12                         Post-Closing Adjustment .  The Closing Merger Consideration shall be adjusted after the Closing as follows:

(a)                                  As soon as practicable, but in any event within one hundred and twenty (120) days following the Closing Date, the Buyer shall deliver, or cause to be delivered, to the Company Equityholder Representative an unaudited balance sheet of the Company (the “ Preliminary Closing Date Balance Sheet ”) as of the close of business on the Closing Date prepared in accordance with GAAP (applied on a basis consistent with the application thereof to the Financial Statements) and in the form and format of Exhibit E .

(b)                                  Subject to the resolution of any disputes pursuant to this Section 1.12 , within five (5) business days after the determination of the Final Closing Date Balance Sheet (as defined below):

(i)                                      (A) if the sum of the Estimated Net Working Capital and the Estimated Closing Cash exceeds (B) the sum of the Closing Net Working Capital and the Closing Cash (such amount resulting from subtracting the amount described in the foregoing clause (ii) from the amount described in the foregoing clause (i) being referred to hereinafter as the “ Closing Shortfall ”), the Buyer shall be entitled to a payment from the Company Equityholders in an amount equal to the Closing Shortfall, which shall be treated as a downward adjustment to the Closing Merger Consideration payable to the Company Equityholders for Tax purposes; and

(ii)                                   (A) if the sum of the Closing Net Working Capital and the Closing Cash exceeds (B) the sum of Estimated Net Working Capital and the Estimated Closing Cash (such amount resulting from subtracting the amount described in the foregoing clause (ii) from the amount described in the foregoing clause (i) being referred to hereinafter as the “ Closing Excess ”), the Company Equityholders shall be entitled to a payment from the Buyer, in accordance with Section 1.16 , in an amount equal to the Closing Excess, which shall be treated as an upward adjustment to the Closing Merger Consideration payable to the Company Equityholders for Tax purposes.

8

pursuant to Article VII which have previously been satisfied from the General Escrow Amount or which are then pending) , the excess shall be deducted from the first proceeds of any Future Payments otherwise available for distribution to the Company Equityholders .

(d)                                  As of the thirtieth (30 th ) day following the delivery thereof to the Company Equityholder Representative, the Preliminary Closing Date Balance Sheet shall be final, binding and conclusive on the Parties and all Company Equityholders for purposes of this Section 1.12 unless, prior to such thirtieth (30 th ) day, the Company Equityholder Representative shall have notified the Buyer in writing of each item on the Preliminary Closing Date Balance Sheet disputed by the Company Equityholder Representative, specifying the amount thereof in dispute and setting forth, in reasonable detail, the basis for such dispute.  In the event of such a dispute, the Buyer and the Company Equityholder Representative shall attempt to reconcile their differences.  If the Buyer and the Company Equityholder Representative are unable to reach a resolution within twenty (20) days after receipt by the Buyer of the Company Equityholder Representative’s written notice of such dispute, the Buyer and the Company Equityholder Representative shall submit the items remaining in dispute for resolution to the Neutral Accountant, which shall, within thirty (30) days of such submission, determine and report to the Company Equityholder Representative and the Buyer upon such remaining disputed items, and such report shall be final, binding and conclusive on all Parties and the Company Equityholders.  In resolving any disputed items, the Neutral Accountant shall apply the accounting principles described in Section 1.12(a) .  The Neutral Accountant shall act as an expert and not as an arbitrator.  The Preliminary Closing Date Balance Sheet that has not been challenged, has been reconciled, or has been determined by the Neutral Accountant pursuant to this Section 1.12 is referred to herein as the “ Final Closing Date Balance Sheet ” and shall be final, binding and conclusive on all Parties and the Company Equityholders for purposes of this Section 1.12 .  The fees and disbursements of the Neutral Accountant shall be allocated equally between the Buyer, on the one hand, and the Company Equityholders, on the other hand.  The Parties agree that the procedures set forth in this Section 1.12(d)  for resolving disputes with respect to the Preliminary Closing Date Balance Sheet, the Closing Shortfall, the Closing Excess, the Closing Net Working Capital or the Closing Cash shall (notwithstanding anything to the contrary contained in this Agreement) be the sole and exclusive procedures for resolving any such disputes, provided that nothing herein shall preclude any Party from instituting litigation in a court of competent jurisdiction to enforce the determination of the Neutral Accountant or any agreement of the Parties with respect to the resolution of any such dispute.

(e)                                   Within five (5) business days after the determination of the Final Adjustment Amount (as defined in Schedule 1.12(e) ): (i) if the Final Adjustment Amount is greater than zero, (A) the Buyer shall be entitled to a payment in an amount equal to the Final Adjustment Amount, which shall be treated as a downward adjustment to the Closing Merger Consideration payable to the Company Equityholders for Tax purposes, and (B) the Buyer and the Company Equityholder Representative shall deliver to the Escrow Agent a joint instruction letter signed by each such Party instructing the Escrow Agent to disburse from the Adjustment Escrow Fund an amount in cash equal to the Final Adjustment Amount to one or more accounts designated by the Buyer and, to extent the Final Adjustment Amount exceeds the available Adjustment Escrow Fund, from the General Escrow Fund (it being agreed that, if the Final Adjustment Amount exceeds the amount of the then available Adjustment Escrow Fund and the then available General Escrow Fund, the Buyer may deduct the Final Adjustment Amount from the first proceeds of any Future Payments otherwise available for distribution to the Company Equityholders); and (ii) the Buyer

9

and the Company Equityholder Representative shall deliver to the Escrow Agent a joint instruction letter signed by each such Party instructing the Escrow Agent to disburse, for the benefit of the Company Equityholders in accordance with Section 1.16 , from the Adjustment Escrow Fund an amount in cash equal to the amount, if any, by which the Adjustment Escrow Fund exceeds the Final Adjustment Amount.  The Parties shall comply with their respective obligations set forth on Schedule 1.12(e) .

10.3        Third-Party Beneficiaries .  The terms and provisions of this Agreement are intended solely for the benefit of the Buyer, Merger Sub, the Company, the Company Equityholder Representative and their respective successors or permitted assigns, and it is not the intention of the parties to confer third-party beneficiary rights, and this Agreement does not confer any such rights, upon any other Person.  For the avoidance of doubt, no Person other than a Party may assert any claim or initiate any Legal Proceeding to enforce any provision of this Agreement.

Any Party may give any notice, request, demand, claim or other communication hereunder using any other means (including personal delivery, expedited courier, messenger service, or ordinary mail), but no such notice, request, demand, claim or other communication that is given by such other means shall be deemed to have been duly given unless and until it actually is received by the party for whom it is intended.  Any Party may change the address to which notices, requests, demands, claims, and other communications hereunder are to be delivered by giving the other Parties notice in the manner herein set forth.

No amendment or waiver effected subsequent to the Closing shall be effective against any Company Equityholder unless such amendment or waiver (a) is signed by the Company Equityholder Representative and (b) either (i) is consented to in writing by such Company Equityholder or (ii) such amendment or waiver applies to all Company Equityholders.

10.11                  Governing Law .  All matters arising out of or relating to this Agreement and the transactions contemplated hereby (including its interpretation, construction, performance and enforcement) shall be governed by and construed in accordance with the internal 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 Laws of any jurisdictions other than those of the State of Delaware.

10.12                  Submission to Jurisdiction .  Each Party (a) consents to submit itself to the exclusive personal jurisdiction of the Court of Chancery of the State of Delaware, New Castle County, or, if that court does not have jurisdiction, a federal court sitting in Wilmington, Delaware in any action or proceeding arising out of or relating to this Agreement or any of the transactions contemplated by this Agreement, (b) agrees that all claims in respect of such action or proceeding may be heard and determined in any such court, (c) 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 (d) agrees not to bring any action or proceeding arising out of or relating to this Agreement or any of the transactions contemplated by this Agreement in any other court.  Each Party waives any defense of inconvenient forum to the maintenance of any action or proceeding so brought and waives any bond, surety or other security that might be required of any other party with respect thereto.  Any Party may make service on another Party by sending or delivering a copy of the process to the Party to be served at the address and in the manner provided for the giving of notices in Section

10.14                  Specific Performance .  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.  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 terms and provisions of this Agreement, in each case without posting a bond or undertaking, this being in addition to any other remedy to which they are entitled at Law or in equity.  Each of the Parties agrees that it will not oppose the granting of an injunction, specific performance and other equitable relief on the basis that (a) the Party seeking such remedy has an adequate remedy at Law or (b) an award of specific performance is not an appropriate remedy for any reason at Law or equity.

10.15                  Construction .
