8

(b)                                 Exchange Procedures.  Promptly after the Effective Time (but in no event later than three (3) Business Days), the Buyer shall cause the Exchange and Paying Agent to mail to each holder of record of Company Stock that was issued and outstanding as of immediately prior to the Effective Time (i) a Letter of Transmittal and (ii) instructions for effecting the surrender of such Certificate in exchange for the applicable Aggregate Consideration that is or may become payable with respect thereto pursuant to the terms of this Agreement.  Upon (A) proper surrender of a Certificate for cancellation to the Exchange and Paying Agent and (B) delivery of a duly completed and executed Letter of Transmittal, the holder of such Certificate shall be entitled to receive in exchange therefor the number of shares of Buyer Common Stock as determined in accordance with Section 2.1 and reflected on the Allocation Schedule attached to the Payment Certificate.  If payment in respect of any Certificate is to be made to a Person other than the Person in whose name such Certificate is registered, it shall be a condition of payment that the Certificate so surrendered shall be transferable and be properly endorsed or shall otherwise be in proper form for transfer, that the signatures on such Certificate or any related stock power shall be properly guaranteed and that the Person requesting such payment shall have established to the reasonable satisfaction of the Buyer and the Exchange and Paying Agent that any transfer and other Taxes required by reason of such payment to a Person other than the registered holder of such Certificate have been paid or are not applicable. Until surrendered as contemplated by this Section 2.2(b), each Certificate shall be deemed at all times after the Effective Time to represent only the right to receive upon such surrender the applicable Aggregate Consideration that becomes payable in respect of such Certificate pursuant to this Agreement.  Holders of Certificates shall not be entitled to receive any portion of the Aggregate Consideration to which they would otherwise be entitled until such Certificates are properly surrendered.

(c)                                  No Further Ownership Rights in Company Stock.  All consideration paid following the surrender for exchange of Certificates evidencing shares of Company Stock (including any Future Payments payable with respect thereto) in accordance with the terms hereof shall be deemed to have been paid in satisfaction of all rights pertaining to such shares of Company Stock, and from and after the Effective Time there shall be no further registration of transfers on the stock transfer books of the Surviving Entity of the shares of Company Stock which were outstanding as of immediately prior to the Effective Time.  If, after the Effective Time, Certificates are presented to the Surviving Entity or the Exchange and Paying Agent for any reason, they shall be cancelled and exchanged as provided in this Article II, subject to Section 2.2(e).

(d)                                 Termination of Payment Fund.  Any portion of the Payment Fund deposited with the Exchange and Paying Agent (including shares of Buyer Common Stock issued to a Buyer reserve account) that remains undistributed to the holders of Company Stock as of one (1) year after the Effective Time shall be delivered to the Buyer (subject to abandoned property, escheat or similar Law), upon demand, and any holder of Company Stock who is entitled to such amount under this Section 2.2 shall (subject to Section 2.2(e)) be entitled to seek payment of such amount from the Buyer only as a general creditor thereof.

(e)                                  No Liability.  To the extent permitted by applicable Law, none of the Buyer, the Merger Subsidiaries, the Company, the Surviving Entity or the Exchange and Paying Agent shall be liable to any Company Equityholder for any amount delivered to a public official

9

pursuant to any applicable abandoned property, escheat or similar Law.

(f)                                   Lost Certificates.  If any Certificate shall have been lost, stolen or destroyed, upon the making of an affidavit of that fact and a customary indemnification of the Company and the Buyer in a form reasonably satisfactory to the Buyer by the Person claiming such Certificate to be lost, stolen or destroyed, the Exchange and Paying Agent shall pay in exchange for such lost, stolen or destroyed Certificate the Aggregate Consideration payable in respect thereof pursuant to this Agreement.  The Exchange and Paying Agent or the Buyer may, in its discretion and as a condition precedent to the payment thereof, require the owner of such lost, stolen or destroyed Certificate to give the Exchange and Paying Agent and/or the Buyer a bond in such sum as it may reasonably direct as an indemnity against any claim that may be made against the Exchange and Paying Agent or the Buyer with respect to the Certificate alleged to have been lost, stolen or destroyed.

2.3                               Dissenting Shares.

(a)                                 Notwithstanding anything to the contrary contained in this Agreement, Dissenting Shares shall not be converted into or represent the right to receive any portion of the Aggregate Consideration in accordance with Section 2.1, but shall be entitled only to such rights as are granted by the DGCL to a holder of Dissenting Shares.

(b)                                 If any Dissenting Shares shall lose their status as such (through failure to perfect or otherwise), then, as of the later of the Effective Time or the date of loss of such status, such shares shall automatically be converted into and shall represent only the right to receive any portion of the Aggregate Consideration otherwise payable in respect thereof pursuant to this Agreement, without interest thereon, upon surrender of the Certificate formerly representing such shares.

(c)                                  The Company shall give the Buyer (i) prompt notice of any written demand for appraisal received by the Company prior to the Effective Time pursuant to the DGCL, any withdrawal of any such demand and any other demand, notice or instrument delivered to the Company prior to the Effective Time pursuant to the DGCL that relates to such demand and (ii) the opportunity to direct all negotiations and proceedings with respect to any such demand, notice or instrument.  The Company shall not settle or make any payment or settlement offer prior to the Effective Time with respect to any such demand, notice or instrument unless the Buyer shall have given its written consent to such settlement, payment or settlement offer.

2.4                               Company Equityholder Representative.

(b)                                 All decisions and actions of the Company Equityholder Representative on behalf of the Company Equityholders shall be deemed to be facts ascertainable outside of this Agreement and shall be binding upon all Company Equityholders and their respective successors, and no Company Equityholder shall have the right to object, dissent, protest or otherwise contest the same. The Company Equityholder Representative shall be entitled to: (i) rely upon the Allocation Schedule, (ii) rely upon any signature believed by it to be genuine, and (iii) reasonably assume that a signatory has proper authorization to sign on behalf of the applicable Company Equityholder or other party.

(c)                                  At the Effective Time, the Buyer shall pay the Company Equityholder Representative Expense Amount to the Company Equityholder Representative, which Company Equityholder Representative Expense Amount shall be maintained by the Company Equityholder Representative in a segregated account.  The Company Equityholder Representative is not providing any investment supervision, recommendations or advice and shall have no responsibility or liability for any loss of principal of the Company Equityholder Expense Amount other than as a result of its gross negligence or willful misconduct.  The Company Equityholder Representative is not acting as a withholding agent or in any similar capacity in connection with the Company Equityholder Expense Amount, and has no tax reporting or income distribution obligations.  The Company Equityholders will not receive any interest on the Company Equityholder Expense Amount and assign to the Company Equityholder Representative any such interest.  Subject to Advisory Group approval, the Company Equityholder Representative may contribute funds to the Company Equityholder Expense Amount from any consideration otherwise distributable to the Company Equityholders.  The Company Equityholder Representative shall be reimbursed for any Company Equityholder Representative Expenses or any other reasonable out-of-pocket expenses incurred in the performance of the Company Equityholder Representative’s duties (including the reasonable fees and expenses of counsel) under this Agreement and under the Company Equityholder Representative Engagement Agreement from the Company Equityholder Representative Expense Amount and, if the remaining Company Equityholder Representative Expense Amount is insufficient to pay such expenses, from the first proceeds from any Future Payments otherwise available for distribution to the Company Equityholders or directly from the Company Equityholders.  In no event shall the Buyer or the Surviving Entity (or any of their respective Affiliates) be obligated to reimburse the Company Equityholder Representative for any such

12

expenses.  Upon the determination of the Company Equityholder Representative that retaining any portion of the Company Equityholder Representative Expense Amount is no longer necessary, the Company Equityholder Representative shall deliver any then remaining portion of the Company Equityholder Representative Expense Amount (the “Company Equityholder Representative Account Payment”) to the Buyer, which will promptly pay (i) a portion thereof equal to the Pro Rata Share that is represented by each share of Company Stock converted pursuant to Section 2.1(c) to the Exchange and Paying Agent for payment to the holder thereof and (ii) a portion thereof equal to the Pro Rata Share that is represented by each Company Equity Award to the Surviving Entity for payment to the holder thereof (which amount shall be paid by the Surviving Entity or the Exchange and Paying Agent to such holder, subject to any applicable withholding as provided in Section 2.9).  The Company Equityholder Representative shall prior to any disbursement of funds for the benefit of Company Equityholders pursuant to this Section 2.4(c), deliver to the Buyer a Post-Closing Disbursement Certificate in respect of such disbursement.  The Company Equityholder Representative shall hold, invest, reinvest and disburse the Company Equityholder Representative Expense Amount in trust for all of the Company Equityholders, and the Company Equityholder Representative Expense Amount shall not be used for any other purpose and shall not be available to the Buyer to satisfy any claims hereunder.

(d)                                 The Company Equityholder Representative shall act for the Company Equityholders on all of the matters set forth in this Agreement, the Exchange and Paying Agent Agreement, the Company Equityholder Representative Engagement Agreement, or any other agreement contemplated hereby or thereby in the manner the Company Equityholder Representative believes to be in the best interest of the Company Equityholders.  The Company Equityholder Representative is authorized to act on behalf of the Company Equityholders notwithstanding any dispute or disagreement among the Company Equityholders.  The Company Equityholder Representative may, in all questions arising hereunder, rely on the advice of counsel, and the Company Equityholder Representative shall not be liable to any Company Equityholder for anything done, omitted or suffered in good faith by the Company Equityholder Representative based on such advice.  The Company Equityholder Representative undertakes to perform such duties and only such duties as are specifically set forth in this Agreement and no implied covenants or obligations shall be read into this Agreement against the Company Equityholder Representative.  The Company Equityholder Representative shall not have any liability to any of the Company Equityholders for any act done or omitted hereunder or under the Company Equityholder Representative Engagement Agreement as Company Equityholder Representative while acting in good faith unless such act done or omitted was in willful violation of Law or resulted from its gross negligence, fraud or bad faith in the performance of such duties under this Agreement.  The Company Equityholder Representative Group (as defined below) shall be indemnified by the Company Equityholders from and against any loss, liability, claim, damage, fee, fine, cost, judgment, amounts paid in settlement or expense incurred in good faith on the part of the Company Equityholder Representative and arising out of or in connection with the acceptance or administration of the Company Equityholder Representative’s duties hereunder and under the Company Equityholder Representative Engagement Agreement (collectively, the “Company Equityholder Representative Expenses”).  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 Company Equityholder Representative Expense, from the first proceeds from any Future Payments

13

otherwise available for distribution to the Company Equityholders or by a claim against the Company Equityholders (with each Company Equityholder liable for the Pro Rata Fraction of any such claim that is represented by such Company Equityholder’s Company Stock and Company Equity Awards). In no event shall the Buyer or the Surviving Entity (or any of their respective Affiliates) be responsible for any fees, costs or expenses of the Company Equityholder Representative. Notwithstanding the foregoing, no Company Equityholder shall be liable to the Company Equityholder Representative for any amount in excess of the aggregate amount of Aggregate Consideration such Company Equityholder has received in connection with the Closing (less any amounts actually paid by such Company Equityholder for any other claim for indemnification under this Agreement). In the event the Company Equityholder Representative becomes unable to perform the Company Equityholder Representative’s responsibilities hereunder or resigns from such position, the Company Equityholders (acting by a written instrument signed by holders of Company Stock who held, as of immediately prior to the Effective Time, a majority (by voting power) of the then outstanding shares of Company Stock) shall select another representative to fill the vacancy of the Company Equityholder Representative, and such substituted representative shall be deemed to be the Company Equityholder Representative for all purposes of this Agreement, or any other agreement contemplated hereby. The Company Equityholder Representative may be removed only upon delivery of written notice to the Buyer signed by the Advisory Group; provided, that no such removal shall be effective until such time as a successor Company Equityholder Representative shall have been validly appointed hereunder.  The Company Equityholder Representative shall provide the Buyer prompt written notice of any replacement of the Company Equityholder Representative, including the identity and address of the new Company Equityholder Representative.  The immunities and rights to indemnification shall survive the resignation or removal of the Company Equityholder Representative or any member of the Advisory Group and the Closing and/or any termination of this Agreement.

(e)                                  The Company Equityholder Representative agrees not to, directly or indirectly, disclose the existence or terms of this Agreement or any other agreement contemplated hereby or any other information regarding this Agreement, the Merger or any of the other matters contemplated hereby, including information provided to the Company Equityholder Representative pursuant to the terms of this Agreement, except, in each case (i) to the extent such information is or becomes generally known to the public (other than as a result of a disclosure by the Company Equityholder Representative in breach of its obligations under this Section 2.4), (ii) if and to the extent required by applicable Law, (iii) to employees, advisors, agents or consultants of the Company Equityholder Representative and to the Company Equityholders, in each case who have a need to know such information, and further provided that such Persons are subject to confidentiality obligations with respect thereto, or (iv) in connection with, and only to the extent required for, enforcement of rights or defense of claims (including, in each case, on behalf of the Company Equityholders) under this Agreement and the transactions contemplated hereby.

(f)                                   Advisory Group.  Certain Company Equityholders have entered into an engagement agreement (the “Company Equityholder Representative Engagement Agreement”) with the Company Equityholder Representative to provide direction to the Company Equityholder Representative in connection with its services under this Agreement and the Company Equityholder Representative Engagement Agreement (such Company Equityholders,

14

including their individual representatives, collectively hereinafter referred to as the “Advisory Group”). As solely between the Company Equityholders and the Company Equityholder Representative, neither the Company Equityholder Representative nor its members, managers, directors, officers, contractors, agents and employees nor any member of the Advisory Group (collectively, the “Company Equityholder Representative Group”) shall be liable for any act done or omitted hereunder or under the Company Equityholder Representative Engagement Agreement as Company Equityholder Representative while acting in good faith, and any act done or omitted to be done pursuant to the advice of counsel shall be conclusive evidence of such good faith.

(g)                                  For all purposes of this Agreement:

(i)                                     the Buyer shall be entitled to rely conclusively on the instructions and decisions of the Company Equityholder Representative as to the settlement of any disputes or claims under this Agreement or any agreements ancillary hereto, including, the Exchange and Paying Agent Agreement, or any other agreement contemplated hereby or thereby, or any other actions required or permitted to be taken by the Company Equityholder Representative hereunder or thereunder, and no party hereunder or any Company Equityholder shall have any claim, cause of action, objection or complaint against the Buyer for any action taken by the Buyer in reliance upon the instructions or decisions of the Company Equityholder Representative;

(ii)                                  except as specifically set forth herein, no Company Equityholder shall have any right to bring any claim, cause of action, objection or complaint except through the Company Equityholder Representative, and the Company Equityholder Representative shall have the sole authority to act for, and to enforce the rights of, all Company Equityholders in connection with this Agreement and the transactions contemplated hereby;

(iii)                               the provisions of this Section 2.4 and the powers, immunities and rights to indemnification granted to the Company Equityholder Representative Group hereunder: (A) are independent and severable, are irrevocable (subject only to Section 2.4(d)) and coupled with an interest and shall be enforceable notwithstanding any rights or remedies that any Company Equityholder may have in connection with the transactions contemplated by this Agreement and (B) shall survive the delivery of an assignment by any Company Equityholder of the whole or any fraction of his, her or its interest in the Future Payments; and

(iv)                              the provisions of this Section 2.4 shall be binding upon the executors, heirs, legal representatives, personal representatives, successor trustees and successors of each Company Equityholder, and any references in this Agreement to a Company Equityholder shall mean and include the successors to the rights of each applicable Company Equityholder hereunder, whether pursuant to testamentary disposition, the Laws of descent and distribution or otherwise.

2.5                               Treatment of Company Equity Awards.

(a)                                 As of immediately prior to the Effective Time, each Company Option that is then outstanding (whether such Company Option is vested or unvested, but not to the extent it has theretofore been exercised) shall vest in full (if unvested in whole or in part) and shall be

15

converted, in settlement and cancellation thereof, into the right to receive an amount equal to (i) (A) such Company Option’s Pro Rata Share of the Aggregate Residual Closing Consideration, if any, plus (B) such Company Option’s Pro Rata Share of the portion of all Future Payments that become payable pursuant to the terms of this Agreement, less (ii) the aggregate exercise price of such Company Option, in each case subject to withholding as provided in Section 2.9; provided, however, that notwithstanding anything to the contrary herein, no portion of the Aggregate Consideration shall be payable to any holder of any such Company Option unless and until such holder shall have executed and delivered to the Buyer an executed Optionholder Agreement.

(b)                                 As of immediately prior to the Effective Time, each Company Restricted Stock Award that is unvested in whole or in part shall vest in full (and all outstanding shares of Company Common Stock issued in connection with such Company Restricted Stock Award shall be (A) converted pursuant to Section 2.1(c)(ii)), and (B) subject to the procedures set forth in Section 2.2).

(c)                                  Upon the conversion and cancellation of any Company Equity Award pursuant to this Section 2.5, such Company Equity Award shall no longer represent the right to acquire any shares of Company Stock or other Equity Interests, but shall entitle the holder thereof to receive only the consideration payable in respect thereof pursuant to this Section 2.5.

(d)                                 Prior to or on the date hereof, each holder of Restricted Stock Awards shall have executed and delivered a Support and Joinder Agreement.

(e)                                  The Buyer shall cause the Surviving Entity or, with respect to the holders of Company Options set forth on Schedule 2.5(e), the applicable Exchange and Paying Agent, to pay to each holder of Company Options any amounts payable with respect to each Future Payment (subject to any applicable withholding as provided in Section 2.9) in accordance with Section 2.7 hereof.

(f)                                   The Company has, prior to the date hereof, taken all actions necessary or desirable in connection with the treatment of Company Equity Awards contemplated by this Section 2.5, including obtaining the consent from each holder of any Company Equity Award (unless such consent is not required under the terms of the applicable agreement, instrument or plan).

2.6                               Adjustment Before and After the Closing.  The Estimated Closing Adjustment and the Final Closing Adjustment shall be determined as set forth below in this Section 2.6:

(a)                                 At least 48 hours prior to the execution of this Agreement, the Company delivered to the Buyer a statement (the “Estimated Closing Adjustment Statement”), in the form attached as Schedule 2.6(a)(i) hereto, setting forth the Estimated Closing Adjustment, including an estimated balance sheet of the Company as of the Effective Time (other than with respect to the Closing Net Working Capital, which shall be as of the time specified in such definition).  The Estimated Closing Adjustment Statement and such balance sheet were prepared in accordance with GAAP applied on a basis consistent with the application thereof to the most recent audited financial statements included in the Company Financial Statements (to the extent consistent with GAAP).  Schedule 2.6(a)(ii) attached hereto reflects the Closing Adjustment Items included in

16

the Estimated Closing Adjustment Statement, including estimated amounts in respect thereof as of the date of this Agreement.  During such 48-hour period, the Company provided the Buyer and its accountants with access to the Company and its accountants and with complete and accurate copies of, and reasonable access to, the work papers and supporting records of the Company and its accountants so as to allow the Buyer and its accountants to verify the accuracy of the Estimated Closing Adjustment Statement.

(b)                                 Not later than sixty (60) calendar days after the Closing Date, the Buyer shall deliver to the Company Equityholder Representative the Closing Adjustment Statement, including a balance sheet of the Company as of the Effective Time (other than with respect to the Closing Net Working Capital, which shall be as of the time specified in such definition).  The Closing Adjustment Statement and such balance sheet shall be prepared in accordance with GAAP applied on a basis consistent with the application thereof to the most recent audited financial statements included in the Company Financial Statements (to the extent consistent with GAAP).  The Closing Adjustment Statement delivered pursuant to this Section 2.6(b) shall be accompanied by a statement setting forth the amount, if any, by which the total of the Closing Adjustment Items is greater than, or less than, the Estimated Closing Adjustment.  The Closing Adjustment Statement, as proposed by Buyer pursuant to this Section 2.6(b), shall be deemed for purposes of this Section 2.6 to be the “Final Closing Adjustment Statement,” the Closing Adjustment Items reflected thereon shall be deemed for purposes of this Section 2.6 to be the “Final Closing Adjustment Items” and each shall be final and binding on all parties to this Agreement and on all Company Equityholders, unless the Company Equityholder Representative timely delivers to the Buyer an Objection Notice in accordance with Section 2.6(c).

(c)                                  In the event that the Company Equityholder Representative disputes the Closing Adjustment Statement or the amount of the Closing Adjustment Items, the Company Equityholder Representative shall notify the Buyer in writing (the “Objection Notice”) of the amount, nature and basis of such dispute, within forty-five (45) calendar days after delivery of the Closing Adjustment Statement pursuant to Section 2.6(b).  Any such Objection Notice shall specify those items or amounts as to which the Company Equityholder Representative disagrees, and the Company Equityholder Representative shall be deemed to have agreed with all other items and amounts contained in the Closing Adjustment Statement and the amount of the Closing Adjustment Items delivered pursuant to Section 2.6(b).  In the event of such a dispute, the Buyer and the Company Equityholder Representative shall first negotiate in good faith to reach agreement on the disputed items or amounts in order to determine the amount of the Closing Adjustment Items, which amount shall not be more than the Buyer’s calculation delivered pursuant to Section 2.6(b) nor less than the Company Equityholder Representative’s calculation delivered pursuant to this Section 2.6(c).  If the Buyer and the Company Equityholder Representative reach a final resolution on the Closing Adjustment Statement within forty-five (45) calendar days after the Buyer’s receipt of the Objection Notice (or within any additional period as mutually agreed to between the Buyer and the Company Equityholder Representative), then the Closing Adjustment Statement agreed upon by the Buyer and the Company Equityholder Representative shall be deemed for purposes of this Section 2.6 to be the “Final Closing Adjustment Statement,” the Closing Adjustment Items reflected thereon shall be deemed for purposes of this Section 2.6 to be the “Final Closing Adjustment Items” and each shall be final and binding on all parties to this Agreement and on all Company Equityholders.

17

(d)                                 If the Buyer and the Company Equityholder Representative are unable to resolve the dispute within forty-five (45) calendar days after delivery of the Objection Notice, then any remaining items in dispute shall be submitted to the Neutral Accountant.  All determinations and calculations pursuant to this Section 2.6(d) shall consider only those Closing Adjustment Items that are set forth in the Objection Notice and remain in dispute, shall be a value that is not more than the Buyer’s calculation delivered pursuant to Section 2.6(b) nor less than the Company Equityholder Representative’s calculation delivered pursuant to Section 2.6(c), shall be in writing and shall be delivered to the Buyer and the Company Equityholder Representative as promptly as practicable.  Absent fraud or manifest error, the Closing Adjustment Statement as finally determined by the Neutral Accountant shall be deemed for purposes of this Section 2.6 to be the “Final Closing Adjustment Statement,” the Closing Adjustment Items reflected thereon shall be deemed for purposes of this Section 2.6 to be the “Final Closing Adjustment Items” and each shall be final and binding on all parties to this Agreement and on all Company Equityholders.  In determining the Closing Adjustment Statement and the Closing Adjustment Items, the Neutral Accountant shall act as an expert and not as arbitrator.  A judgment on the determination made by the Neutral Accountant pursuant to this Section 2.6 may be entered in and enforced by any court having jurisdiction thereover.

(e)                                  The fees and expenses of the Neutral Accountant in connection with the resolution of disputes pursuant to Section 2.6(d) shall be borne by the Company Equityholders, on the one hand, and the Buyer, on the other hand, in proportion to the amounts by which the proposals of the Buyer and the Company Equityholder Representative differed from the Neutral Accountant’s final determination.

(f)                                   The “Final Closing Adjustment” shall be a number of shares of Buyer Common Stock equal to (i) the amount of the Final Closing Adjustment Items minus the Estimated Closing Adjustment, divided by (ii) the Buyer Closing Stock Price. For the avoidance of doubt, the Final Closing Adjustment may be a positive or negative number.  If the Final Closing Adjustment is a positive number, then the Buyer shall be entitled to seek recovery of the Final Closing Adjustment from the Holdback Shares and Holdback Fund in accordance with Section 2.1(e); provided, that if the aggregate amount of the Final Closing Adjustment is less than $25,000, the Buyer will not be entitled to seek recovery from the Holdback Shares and Holdback Fund pursuant to Section 2.1(e) or this Section 2.6(f).

(g)                                  From the delivery of the Closing Adjustment Statement until such time as the calculation of the Final Closing Adjustment has been finally determined pursuant to this Section 2.6, the Company Equityholder Representative and its accountants (at the Company Equityholder Representative’s expense on behalf of the Company Equityholders) shall, upon reasonable notice and during normal business hours, be permitted to discuss with the Buyer and its accountants the Closing Adjustment Statement and shall be provided complete and accurate copies of, and have reasonable access, upon reasonable notice at reasonable times during normal business hours, to the work papers and supporting records of the Buyer and its accountants so as to allow the Company Equityholder Representative and its accountants to verify the accuracy of the Closing Adjustment Statement.

(h)                                 The parties agree that the procedures set forth in this Section 2.6 and, subject to Section 5.1(d), recourse against the Holdback Shares shall be the sole and exclusive

18

method for resolving any disputes with respect to the determination of the Final Closing Adjustment Statement, the Final Closing Adjustment Items and the Final Closing Adjustment; provided, that this provision shall not prohibit the Buyer or the Company Equityholder Representative from instituting litigation to enforce the determination of the Neutral Accountant and shall not limit any remedy of any party under Article V.

2.7                               Allocation Schedule; Payments of Future Payments.

(a)                                 The Allocation Schedule sets forth a true, correct and complete summary of the allocation of the Aggregate Closing Consideration payable to the Company Equityholders pursuant to this Agreement.  From time to time after the Effective Time, the Company Equityholder Representative may, with the written agreement of the Buyer, update, correct or otherwise amend or modify the Allocation Schedule in any manner that is consistent with the express provisions of this Article II, including by delivering a Post-Closing Disbursement Certificate that supersedes such Allocation Schedule.  The Buyer shall be entitled to rely conclusively on the Allocation Schedule as in effect from time to time and/or any Post-Closing Disbursement Certificate, as applicable, and, as between the Company Equityholders, on the one hand, and the Buyer and the Surviving Entity, on the other hand, any amounts delivered by the Buyer to any Company Equityholder (or delivered by the Buyer to the Exchange and Paying Agent for delivery) in accordance with the Allocation Schedule and/or Post-Closing Disbursement Certificate, as applicable, in effect from time to time shall be deemed for all purposes to have been delivered to the applicable Company Equityholder in full satisfaction of the obligations of the Buyer and the Surviving Entity under this Article II.

(b)                                 The Exchange and Paying Agent shall pay the portion of the Aggregate Closing Consideration payable to the applicable Company Stockholders in accordance with the Allocation Schedule and the Letters of Transmittal, and the Buyer, the Surviving Entity or the Exchange and Paying Agent as applicable, shall pay the portion of the Aggregate Closing Consideration payable to the holders of Company Options pursuant to Section 2.5 to such holders in accordance with the Allocation Schedule (subject to any applicable withholding as provided in Section 2.9).

(c)                                  The portion of any Future Payment payable in respect of Company Stock shall be paid by the Buyer to the Exchange and Paying Agent for the benefit of the holders thereof, and the portion of any Future Payment payable in respect of Company Options shall be paid (subject to any applicable withholding as provided in Section 2.9) by the Surviving Entity or the Exchange and Paying Agent, as applicable, to such holders, in each case in accordance with the Post-Closing Disbursement Certificate.  The Company Equityholder Representative shall, prior to any disbursement of funds for the benefit of Company Equityholders pursuant to this Section 2.7(c), deliver to the Buyer a Post-Closing Disbursement Certificate in respect of such disbursement.

(d)                                 The parties understand and agree that (i) the Company Equityholders have no rights as a security holder of the Surviving Entity or the Buyer as a result of their right to receive the Future Payments, (ii) without limiting the generality of Section 8.4, no right to receive any Future Payment may be assigned or otherwise transferred without the prior written consent of the Buyer and any purported assignment or transfer in the absence of such consent

19

shall be null and void ab initio, and (iii) no interest is payable as additional consideration with respect to any of the Future Payments.

2.8                               Contingent Payments.  Subject to Section 5.3(f), the Company Equityholders shall be entitled to certain one-time (regardless of the number of times the corresponding milestones are achieved or the number of products with which they are achieved) contingent payments determined as set forth below (each, a “Milestone Payment” and, collectively, the “Contingent Consideration”) based on the achievement of the corresponding events set forth below (each, a “Milestone Event”) by Buyer or the Surviving Entity or any of its or their Affiliates or licensees:

(a)                                 Milestone Payments.

(b)                                 Procedures; Limitations.

(i)                                     Within ten (10) calendar days following the first achievement of a Milestone Event, the Buyer shall notify the Company Equityholder Representative that such Milestone Event has been achieved, and no later than thirty (30) calendar days following the date of the first achievement of such Milestone Event (the date of each such first achievement, each a “Milestone Achievement Date”) the Buyer (or its designee) shall (A) deliver, in accordance with Section 2.7, for the benefit of the Company Equityholders, a number of shares of Buyer Common Stock equal to the applicable Milestone Amount divided by the Buyer Post-Closing

20

Stock Price, or (B) if the issuance of such shares of Buyer Common Stock pursuant to this Section 2.8, together with all other issuances of Buyer Common Stock pursuant to this Agreement issued prior to such date, would cause the Share Cap to be exceeded, pay any such excess Contingent Consideration in cash to the Exchange and Paying Agent, in each case, for prompt distribution to the Company Equityholders in accordance with Section 2.7 and the applicable Post-Closing Disbursement Certificate; provided, that the “determination date” for purposes of determining the Buyer Post-Closing Stock Price under this Section 2.8(b)(i) shall be the Milestone Achievement Date for such Milestone Event.

(ii)                                  Each of the Milestone Payments shall only be payable once, upon the first occurrence of the corresponding Milestone Event, and no additional payment will be due in the event of any repeated occurrence of any such Milestone Event.  No Milestone Payment shall be payable with respect to any Milestone Event that is first achieved after the end of the Payment Term.

(iii)                               If, during the Payment Term, there occurs a Milestone Successor Event in which the Buyer is not the surviving parent entity, then the Successor Entity shall pay any Milestone Payment that becomes due and payable in cash.

(c)                                  Buyer shall, collectively with the Surviving Entity and its or their applicable assignees and delegates, and any applicable Affiliates and licensees of any of the foregoing, keep reasonable documentation relating to the Milestone Products.  For each calendar year during the Payment Term beginning with the calendar year ending on December 31, 2018, Buyer shall provide the Company Equityholder Representative with an annual development report within forty-five (45) calendar days after the end of such calendar year summarizing in reasonable detail (i) the status of efforts of Buyer or the Surviving Entity or any of its or their assignees or delegates, or any Affiliates or licensees of any of the foregoing, during such calendar year, to develop, to the extent required under Section 2.8(d), at least one Lead Diligence Product through the dosing of a first patient in the first Phase II Clinical Trial (or, if no such Phase II Clinical Trial is earlier commenced, dosing of a first patient in the first Phase III Clinical Trial) of such Lead Diligence Product for the treatment of Geographic Atrophy and any modifications to the Development Plan during the prior calendar year and (ii) the progress, if any, during such calendar year to achieve other Milestone Events.  Buyer shall respond to reasonable follow-up questions from the Company Equityholder Representative regarding such reports and, if the Company Equityholder Representative requests meeting(s) with representatives of Buyer to discuss such annual report(s), up to three (3) representatives of each of Buyer and the Company Equityholders shall meet to discuss such questions in person or via teleconference, not more often than once in any calendar year, with such representatives of Buyer including at least one executive of the Buyer having primary operating responsibility with respect to the development of the Milestone Products by the Buyer or the Surviving Entity or any of its or their assignees or delegates, or any Affiliates or licensees of any of the foregoing, as applicable.  Following each such meeting relating to a report described in clause (i) above, upon the reasonable request of the Company Equityholder Representative, Buyer shall provide copies of and access to material data and final reports of the activities conducted under the Development Plan and relied upon for the preparation of the annual report or portion thereof that relates to the efforts described in clause (i) above for inspection and copying for the purpose of

21

determining the status and progress of the development of the Milestone Product described in clause (i) above.

(d)                                 Each of the Company Equityholders, by his, her or its execution of a Support and Joinder Agreement, a Written Consent, an Optionholder Agreement, a Letter of Transmittal and/or receipt of Aggregate Consideration hereunder, acknowledges and agrees that: (i) nothing herein shall constitute a guarantee by the Buyer of the achievement of any or all of the Milestone Events; and (ii) subject only to the immediately succeeding sentence, (A) Buyer shall have the sole decision-making authority over the development of the Milestone Products; (B) Buyer is entitled to conduct the business of the Surviving Entity and with respect to any Milestone Products in a manner that is in the best interests of Buyer and its shareholders (without taking into account its obligations to Company Equityholders under this Section 2.8), and shall have the absolute right and sole and absolute discretion to operate and otherwise make decisions with respect to the conduct of the business of the Surviving Entity with respect to the development of the Milestone Products or the achievement of any Milestone Events and to take or refrain from taking any action with respect to the development of any Milestone Products or the achievement of any Milestone Events; and (C) Buyer or an Affiliate of Buyer currently or may in the future offer or develop products or services that compete, either directly or indirectly, with the Milestone Products and may make decisions with respect to such products and services that may adversely affect the development of the Milestone Products or the achievement of any Milestone Event.  Notwithstanding anything set forth in the immediately foregoing sentence, during the Payment Term, the Buyer shall, collectively with the Surviving Entity and its or their applicable assignees and delegates, and any applicable Affiliates and licensees of any of the foregoing, use Commercially Reasonable Efforts to perform the activities specified in the Development Plan with respect to the development of a Lead Diligence Product through the dosing of a first patient in the first Phase II Clinical Trial (or, if no such Phase II Clinical Trial is earlier commenced, dosing of a first patient in the first Phase III Clinical Trial) of such Lead Diligence Product for the treatment of Geographic Atrophy.  The Buyer’s maximum aggregate liability for any and all breaches by the Buyer of its obligations under this Section 2.8 shall be limited to the unpaid portion, if any, of the Milestone Payment for the Milestone Event set forth in Section 2.8(a)(vi) and all documented and reasonable legal fees and other documented and reasonable out-of-pocket costs and expenses incurred by the Company Equityholder Representative and the Company Equityholders for the successful assertion of any claim of non-payment under this Section 2.8, and neither the Buyer nor any of its Affiliates shall have any other liability hereunder to any Company Equityholder or any other Person for any claim, loss or damage of any nature, including claims, losses or damages that arise out of or relate in any way to any decisions or actions affecting whether or not or the extent to which the Contingent Consideration becomes payable in accordance with this Section 2.8; provided, that, for the avoidance of doubt, nothing in this Section 2.8(d) shall modify Buyer’s obligation pursuant to Section 2.8(a) to make any Milestone Payment following the first achievement during the Payment Term of the applicable Milestone Event.

(e)                                  The right of any Company Equityholder to receive any amounts with respect to Contingent Consideration (i) shall not be evidenced by a certificate or other instrument, (ii) shall not be assignable or otherwise transferable by such Company Equityholder, except by will, upon death or by operation of Law and (iii) does not represent any right other than the right to receive the consideration set forth in this Section 2.8.  Any attempted transfer of

22

the right to any amounts with respect to Contingent Consideration by any holder thereof (other than as specifically permitted by the immediately preceding sentence) shall be null and void.

(f)                                   Notwithstanding anything else contained in this Agreement, the Buyer may, without the consent of any other party hereto, effect a Milestone Successor Event; provided, that in the event that a Milestone Successor Event occurs during the Payment Term, (i) the Buyer shall require the relevant transferee, assignee, delegatee or other successor of the Buyer (the “Successor Entity”) pursuant to such Milestone Successor Event, to assume and expressly agree in writing to perform the obligations of the Buyer under and be bound by this Section 2.8 as if such Successor Entity were the original Buyer named in Section 2.8 of this Agreement and (ii) the Company Equityholder Representative (on behalf of the Company Equityholders) is made an express third party beneficiary of such written agreement, and (iii) the Buyer shall provide the Company Equityholder Representative prompt written notice of such Milestone Successor Event.

(g)                                  Notwithstanding any other provision in this Agreement, the Buyer’s obligations to pay any Contingent Consideration hereunder is subject to (i) Section 5.3(f) and (ii) receipt by Buyer of a Post-Closing Disbursement Certificate pursuant to, and in accordance with, Section 2.7(c).

(h)                                 Certain Definitions. As used in this Agreement, the following terms shall have the meanings ascribed to them below:

(i)                                     “Commercially Reasonable Efforts” shall mean with respect to research, development and commercialization of a Lead Diligence Product, use of those efforts and resources, consistent with the exercise of reasonable scientific and business judgment, as are applied by biopharmaceutical companies of comparable size and resources as those of Buyer to a product, resulting from its own research efforts or otherwise owned by such company or to which it has rights, of similar value, stage of development, life cycle and commercial potential, without taking into account the obligation to make any Milestone Payments hereunder or internal programs that compete with the same indication of any Lead Diligence Product.

(ii)                                  “Development Plan” shall mean Buyer’s plan outlining the development activities for developing at least one Lead Diligence Product through the dosing of a first patient in the first Phase II Clinical Trial (or, if no such Phase II Clinical Trial is earlier commenced, dosing of a first patient in the first Phase III Clinical Trial) of such Lead Diligence Product for the treatment of Geographic Atrophy, which is attached as Schedule 2.8(h)(ii) hereto and which Buyer may modify from time to time in its reasonable discretion, provided that Buyer shall not modify such plan or any activities set forth therein in a manner that would reasonably be expected to adversely affect the achievement of the dosing of a first patient in the first Phase II Clinical Trial (or, if no such Phase II Clinical Trial is earlier commenced, dosing of a first patient in the first Phase III Clinical Trial) of such Lead Diligence Product for the treatment of Geographic Atrophy.

(iii)                               “EU” shall mean the economic, scientific and political organization of the European Union as it may be constituted from time to time.

23

(iv)          “Geographic Atrophy” shall mean the ophthalmic disease geographic atrophy, including early forms (i.e. dry age-related macular degeneration) and late forms.  For the avoidance of doubt, Geographic Atrophy and Wet AMD are distinct diseases and neither is a form of the other.

(v)           “Lead Compounds” shall mean each of the proprietary compounds of the Company known as NXT-3683 and NXT-5834, compounds specifically claimed in any Patent Rights within the Company Registrations as of the Closing Date, in each case as listed on Schedule 2.8(h)(v), or any salts, esters, polymorphs, isomers or metabolites thereof, in any form or formulation.

(vi)          “Lead Diligence Product” shall mean a product containing NXT-3683 or NXT-5834, or any salts, esters, polymorphs, isomers or metabolites thereof, in any form or formulation, as an active pharmaceutical ingredient provided that, once the formulation activities set forth in the “Formulation Development” section of the Development Plan are completed and such a product is selected by the Buyer or the Surviving Entity for further development under the Development Plan, the Lead Diligence Product shall thereafter be limited to the selected product.  For the avoidance of doubt, the selection of the Lead Diligence Product pursuant to the proviso in the immediately preceding sentence does not affect the Company Equityholders’ rights to receive the applicable one-time Milestone Payment contemplated by Section 2.8(a) following the first achievement of the corresponding Milestone Event with a Milestone Product, regardless of whether such Milestone Product is the Lead Diligence Product.

(vii)         “MHLW” shall mean the Japanese Ministry of Health, Labour and Welfare or any successor agency thereto.

(viii)        “Milestone Product” shall mean a product containing a Lead Compound as an active pharmaceutical ingredient.

(ix)          “Milestone Successor Event” means any of the following events: (1) a sale, conveyance, assignment or other disposition of all or substantially all of the assets of Buyer and its Subsidiaries on a consolidated basis (other than to the Buyer or any Subsidiary of the Buyer), (2) a merger or consolidation in which Buyer is not the ultimate parent entity and in which the stockholders of Buyer immediately prior to such consolidation or merger own less than fifty percent (50%) of the ultimate parent entity’s voting power as of immediately after the transaction and (3) the sale or transfer by Buyer and/or its Subsidiaries of all or substantially all of its assets related to the Lead Compounds and Milestone Products.

(x)           “New Drug Application” shall mean a New Drug Application (as defined in Title 21, Section 314.50 et seq. of the U.S. Code of Federal Regulations or any successor regulations), including any amendment or supplement thereto, or any comparable application filed in or for jurisdictions outside the US.

(xi)          “Payment Term” shall mean the period of seventeen (17) years immediately following the Closing Date.

(xii)         “Phase II Clinical Trial” shall mean a randomized, controlled human clinical trial that satisfies the requirements of 21 C.F.R. 321.21(b), as the same may be

24

amended from time to time, or its successor regulation or comparable regulation in any jurisdiction outside the US, the principal purpose of which is a preliminary determination of clinical safety and efficacy in a target patient population following an earlier dose-finding human clinical trial.  A Phase II Clinical Trial shall exclude all portions that are phase I clinical trials (i.e., human clinical trials that satisfy the requirements of 21 C.F.R. 321.21(a), as the same may be amended from time to time, or its successor regulation or comparable regulation in any jurisdiction outside the US), but shall include any portion of a phase I/II or a phase II/III clinical trial that satisfies the definition of Phase II Clinical Trial.  For purposes of clarity, a “controlled” clinical trial is one that includes at least one arm of the trial where patients receive as study treatment (a) either sham treatment or standard-of-care treatment and (b) do not receive the applicable Milestone Product being investigated in the trial.

(xiii)        “Phase III Clinical Trial” shall mean a randomized, controlled human clinical trial that satisfies the requirements of 21 C.F.R. 321.21(c) and is intended to establish that a product is safe and efficacious for its intended use and support regulatory approval thereof, or a similar clinical study prescribed by an applicable regulatory authority outside the US. For purposes of clarity, a “controlled” clinical trial is one that includes at least one arm of the trial where patients receive as study treatment (a) either sham treatment or standard-of-care treatment and (b) do not receive the applicable Milestone Compound being investigated in the trial.

(xiv)        “US” shall mean the United States of America and its territories and possessions.

(xv)         “Wet AMD” shall mean the ophthalmic disease wet age-related macular degeneration.

(i)            To the extent that Contingent Consideration payable to Company Equityholders in respect of shares of Company Stock is treated as composed of a principal component and an interest component, as contemplated in 6.2(f)(ii)(A), and such Contingent Consideration is payable in shares of Buyer Common Stock, shares of Buyer Common Stock representing the principal component (with a value equal to the principal component) and shares of Buyer Common Stock representing the interest component (with a value equal to the interest component) shall be represented by separate share certificates or book entry accounts, as the case may be.

2.9          Withholding Rights.  The Buyer, the Company, the Surviving Entity and the Exchange and Paying Agent will be entitled to deduct and withhold from the amounts otherwise payable by it pursuant to this Agreement to any Person, such amounts as it reasonably determines that it is required to deduct and withhold with respect to the making of such payment under the Code, or any provision of state, local or foreign Tax Law, and shall request any necessary Tax forms, including Forms W-8 or W-9, as applicable, or any similar information, from Company Stockholders and any other recipients of payments hereunder to minimize such withholding.  In the event that any amount is so deducted and withheld, and properly remitted to the appropriate Governmental Entity in accordance with applicable Law, such amount will be treated for all purposes of this Agreement as having been paid to the Person to whom the payment from which such amount was withheld was made.

25

2.10        Share Issuance.

(a)           All shares of Closing Buyer Common Stock issued pursuant to this Agreement shall bear a legend (and Buyer will make a notation on its transfer books to such effect) prominently stamped or printed thereon or the substance of which will otherwise be reflected on the books and records of the transfer agent for Buyer Common Stock with respect to book-entry shares, in each case reading substantially as follows:

“THE SECURITIES REPRESENTED HEREBY HAVE NOT BEEN REGISTERED UNDER THE SECURITIES ACT OF 1933, AS AMENDED, OR APPLICABLE STATE SECURITIES LAWS. THESE SECURITIES HAVE BEEN ACQUIRED FOR INVESTMENT AND NOT WITH A VIEW TO RESALE IN CONNECTION WITH A DISTRIBUTION AND MAY NOT BE SOLD OR OTHERWISE TRANSFERRED EXCEPT PURSUANT TO AN EFFECTIVE REGISTRATION STATEMENT FOR SUCH SECURITIES UNDER THE SECURITIES ACT OF 1933, AS AMENDED, AND APPLICABLE STATE SECURITIES LAWS, OR AN EXEMPTION FROM REGISTRATION UNDER SUCH ACT.”

Notwithstanding the foregoing, if the recipient of such Buyer Common Stock is a “non-U.S. person”, a legend in substantially the following form may also be used:

“THESE SECURITIES MAY NOT BE TRANSFERRED EXCEPT IN ACCORDANCE WITH THE PROVISIONS OF REGULATION S UNDER THE SECURITIES ACT OF 1933, AS AMENDED, PURSUANT TO REGISTRATION UNDER THE SECURITIES ACT, OR PURSUANT TO AN AVAILABLE EXEMPTION FROM REGISTRATION.  HEDGING TRANSACTIONS INVOLVING THESE SECURITIES MAY NOT BE CONDUCTED UNLESS IN COMPLIANCE WITH THE SECURITIES ACT.”

(b)           Notwithstanding anything else herein, the Buyer shall not be required to issue shares of Buyer Common Stock pursuant to this Agreement in excess of the Share Cap.

(b)           The Buyer has established and maintains and has, since January 1, 2016, maintained, disclosure controls and procedures and a system of internal control over financial reporting (as such terms are defined in paragraphs (e) and (f), respectively, of Rule 13a-15 under the Exchange Act) in all material respects in compliance with the requirements of Rule 13a-15 under the Exchange Act. From the date of the filing of the Buyer’s Annual Report on Form 10-K for the fiscal year ended December 31, 2016 to the date of this Agreement, the Buyer’s auditors and the Buyer’s board of directors have not been advised of (i) any significant deficiencies or material weaknesses in the design or operation of internal control over financial reporting which are reasonably likely to adversely affect the Buyer’s ability to record, process, summarize and report financial information or (ii) any fraud, whether or not material, that involves management or other employees who have a significant role in the Buyer’s internal control over financial reporting.

49

(b)           All manufacturing, processing, distribution, labeling, storage, testing, specifications and sampling of products performed by or on behalf of the Buyer are in material compliance with all applicable Laws administered or issued by the FDA, the EMA or any other Governmental Entity exercising comparable authority.  The Buyer has not received any written notices or correspondence from the FDA, the EMA or any other Governmental Entity exercising comparable authority, and there is no action or proceeding pending or threatened (including any prosecution, injunction, seizure, civil fine, suspension or recall), in each case alleging that the Buyer is not currently in compliance with any and all applicable Laws implemented by the FDA, the EMA or any other Governmental Entity exercising comparable authority.

4.11        No Other Representations or Warranties.  Buyer is not relying and has not relied on any representations or warranties whatsoever regarding the Company, express or implied, except for the representations and warranties in Article III (including the related portions of the Company Disclosure Schedule).  Such representations and warranties by the Company constitute the sole and exclusive representations and warranties of the Company in connection with the Merger and Buyer understands, acknowledges and agrees that all other representations and warranties of any kind or nature as to the Company, whether express, implied or statutory, are specifically disclaimed by the Company.  In connection with the due diligence investigation of the Company by Buyer, Buyer and its Affiliates, directors, officers, employees, agents, representatives and advisors have received and may continue to receive after the date hereof from the Company and its Affiliates, directors, officers, employees, consultants, agents, representatives and advisors certain estimates, projections, forecasts and other forward-looking information, as well as certain business plan information, regarding the Company and its business and operations.  Buyer hereby acknowledges that there are uncertainties inherent in attempting to make such estimates, projections, forecasts and other forward-looking statements, as well as in such business plans, and that Buyer will have no claim against the Company, or any of its Affiliates, directors, officers, employees, consultants, agents, representatives or advisors, or any other Person with respect thereto unless any such information is expressly addressed or included in a representation or warranty contained in this Agreement.  Accordingly, Buyer hereby acknowledges and agrees that neither the Company nor any of its Affiliates, directors, officers, employees, consultants, agents, representatives or advisors, nor any other Person, has

50

made or is making any express or implied representation or warranty with respect to such estimates, projections, forecasts, forward-looking statements or business plans unless any such information is expressly addressed or included in a representation or warranty made by the Company contained in this Agreement.

ARTICLE V

5.1          Indemnification by the Company Equityholders.  The Company Equityholders shall, from and after the Effective Time, on a several and not joint basis in accordance with their respective Pro Rata Fraction, defend and indemnify the Buyer in respect of, and hold it harmless against and will compensate and reimburse the Buyer for, any and all Damages incurred or suffered by any Buyer Indemnified Party (regardless of whether such Damages relate to any Third Party Action) arising or resulting from, relating to or constituting:

(a)           any breach, as of the date of this Agreement (except to the extent expressly made as of an earlier date, in which case any inaccuracy of any representations and warranties as of such earlier date), of any representation or warranty of the Company contained in this Agreement (as such representations and warranties are modified by the Company Disclosure Schedule delivered contemporaneously with this Agreement) or the certificate furnished by the Company to the Buyer pursuant to Section 1.2(b)(H) of this Agreement;

(b)           any failure to perform any covenant or agreement of the Company to be performed prior to the Closing contained in this Agreement;

(c)           any Pre-Closing Taxes;

(d)           any Individual Contractor Amounts, any Closing Indebtedness, and any Company Transaction Expenses, in each case to the extent in excess of the amounts, if any, included in the calculation of the Aggregate Closing Consideration or the Final Closing Adjustment;

(e)           any claim by a stockholder or former stockholder of the Company, or any other Person seeking to assert, or based upon:  (i) the ownership or rights to ownership of any shares of stock of the Company; (ii) any rights of a stockholder (other than the right to receive the consideration pursuant to Article II), including any option, preemptive right or rights to notice or to vote; (iii) any rights under the Organizational Documents of the Company; (iv) any claim that his, her or its shares were wrongfully repurchased by the Company; or (v) any claim for appraisal or dissenters rights, including any payment in respect of Dissenting Shares in excess of the amount of payments otherwise payable to the stockholder seeking such rights under this Agreement;

(f)            any inaccuracy in the Allocation Schedule, as in effect from time to time; or

51

(g)           any fraud with respect to any representation or warranty of the Company contained in this Agreement (as such representations and warranties are modified by the Company Disclosure Modifications).

5.2          Indemnification by Buyer.  Subject to the terms and limitations set forth in this Article V, from and after the Effective Time, the Buyer shall, indemnify the Company Equityholders in respect of any and all Damages incurred or suffered by any Equityholder Indemnified Party (regardless of whether such Damages relate to any Third Party Action) resulting from, relating to or constituting:

(a)           any breach, as of the date of this Agreement (except to the extent expressly made as of an earlier date, in which case any inaccuracy of any representations and warranties as of such earlier date), of any representation or warranty of the Buyer or any Merger Subsidiary contained in this Agreement (as such representations and warranties are modified by the Buyer SEC Reports and/or the Buyer Disclosure Schedule delivered contemporaneously with this Agreement);

(b)           any failure to perform any covenant or agreement of Buyer or any Merger Subsidiary contained in this Agreement; or

(c)           any fraud with respect to any representation or warranty of the Buyer or any Merger Subsidiary contained in this Agreement (as such representations and warranties are modified by the Buyer Disclosure Modifications).

5.3          Indemnification Claims.

(a)           An Indemnified Party shall give written notification to the Indemnifying Party (which, in the case where the Company Equityholders are the Indemnifying Party, shall be given to the Company Equityholder Representative) of the commencement of any Third Party Action.  Such notification shall be given within twenty (20) calendar days after receipt by the Indemnified Party of the notice of such Third Party Action, and shall describe in reasonable detail (to the extent then known by the Indemnified Party) the facts constituting the basis for such Third Party Action and the amount of the claimed Damages and shall be accompanied by copies of any documentation submitted by the third party taking such Third Party Action.  No delay or failure on the part of an Indemnified Party in so notifying the Indemnifying Party shall relieve the Indemnifying Party of any liability or obligation hereunder except to the extent of any damage or liability caused by or arising out of such delay or failure.  Within twenty (20) calendar days after delivery of such notification, the Indemnifying Party may, upon written notice thereof to the Indemnified Party, assume control of the defense of such Third Party Action with counsel reasonably satisfactory to the Indemnified Party; provided, that (i) the Indemnifying Party may only assume control of such defense if (A) it acknowledges in writing to the Indemnified Party that, subject to the limitations of this Article V, the Indemnified Party shall be entitled to Damages incurred or suffered by it and resulting from or relating to such Third Party Action, (B) in the case where the Indemnified Party is the Buyer, an adverse resolution of the Third Party Action would not have a material adverse effect on the goodwill or reputation of the Buyer or the business, operations or future conduct of the Buyer and (ii) the Indemnifying Party may not assume control of the defense of any Third Party Action involving Taxes, any Governmental

52

Entity or criminal liability or in which equitable relief is sought against the Buyer or any of its Subsidiaries.  If the Indemnifying Party does not, or is not permitted under the terms hereof to, so assume control of the defense of a Third Party Action, the Indemnified Party shall control such defense.  The Non-controlling Party may participate in such defense at its own expense.  The Controlling Party shall keep the Non-controlling Party advised of the status of such Third Party Action and the defense thereof and shall consider in good faith recommendations made by the Non-controlling Party with respect thereto.  The Non-controlling Party shall furnish the Controlling Party with such information as it may have with respect to such Third Party Action (including copies of any summons, complaint or other pleading which may have been served on such party and any written claim, demand, invoice, billing or other document evidencing or asserting the same) and shall otherwise cooperate with and assist the Controlling Party in the defense of such Third Party Action.  The Controlling and Non-controlling Party shall cooperate in the defense or prosecution of such Third Party Action.  Such cooperation shall include the retention and (upon the Company Equityholder Representative’s request) the provision to the Company Equityholder Representative of records and information which are reasonably relevant to such Third Party Action, and making employees and other representatives and advisors available on a mutually convenient basis to provide additional information and explanation of any material provided hereunder.  The reasonable fees and expenses of counsel to the Indemnified Party with respect to a Third Party Action (x) may be considered Damages if the Indemnifying Party elects not to control the defense of such Third Party Action pursuant to the terms of this Section 5.3(a) and indemnification is thereafter determined to be appropriate and/or (y) shall be considered Damages for purposes of this Agreement if the Indemnifying Party assumes control of such defense and the Indemnified Party reasonably concludes that the Indemnifying Party and the Indemnified Party have conflicting interests or different defenses available with respect to such Third Party Action (provided, however, that in no event shall the Company Equityholder Representative be responsible for the fees and expenses of more than one counsel for all Buyer Indemnified Parties).  The Indemnifying Party shall not agree to any settlement of, or the entry of any judgment arising from, any Third Party Action without the prior written consent of the Indemnified Party which shall not be unreasonably withheld, conditioned or delayed; provided, that the consent of the Indemnified Party shall not be required if the Indemnifying Party, agrees in writing to pay any amounts payable pursuant to such settlement or judgment and such settlement or judgment includes a complete release of the Indemnified Party from further liability and has no other adverse effect on the Indemnified Party.  The Indemnified Party shall not agree to any settlement of, or the entry of any judgment arising from, any such Third Party Action without the prior written consent of the Indemnifying Party, which shall not be unreasonably withheld, conditioned or delayed. Notwithstanding anything else herein to the contrary, to the extent there is any conflict between the provisions of this Section 5.3(a) and Section 6.2(d) with regard to any Third Party Action involving Taxes, Section 6.2(d) shall govern.  The existence of any Third Party Claim shall not create a presumption of any breach by a party to this Agreement of any of its representations, warranties or covenants set forth in this Agreement.

(b)           In order to seek indemnification under this Article V (other than pursuant to matters that are addressed by Section 2.6 which shall be governed thereby), the Indemnified Party shall deliver a Claim Notice to the Company Equityholder Representative (acting on behalf of the Company Equityholders in the case of indemnification sought against the Company Equityholders) and Buyer (in the case of indemnification sought against the Buyer).

53

(c)           Within twenty (20) calendar days after delivery of a Claim Notice by the Buyer or the Company Equityholder Representative, the applicable Indemnifying Party shall deliver to the Indemnified Party a Response, in which the Indemnifying Party, shall:  (i) agree that the Indemnified Party is entitled to receive all of the Claimed Amount, (ii) agree that the Indemnified Party is entitled to receive the Agreed Amount or (iii) dispute that the Indemnified Party is entitled to receive any of the Claimed Amount.  If no Response is delivered within such twenty (20)-day period, the Indemnifying Party shall be deemed to have agreed that all of the Claimed Amount is owed to the Indemnified Party.  The Indemnifying Party may not contest the payment of all or a portion of the Claimed Amount, except to the extent it believes in good faith that the Claimed Amount does not constitute Damages for which the Indemnified Party is entitled to indemnification under this Article V.  Acceptance by the Indemnified Party of partial payment of any Claimed Amount shall be without prejudice to the Indemnified Party’s right to claim the balance of any such Claimed Amount.

(d)           If the Company Equityholder Representative in such Response disputes payment of all or part of the Claimed Amount, the Company Equityholder Representative and Buyer shall use good faith efforts to resolve such Dispute.  If such Dispute is not resolved within sixty (60) calendar days following the delivery by the Company Equityholder Representative of such response any Dispute shall be resolved in accordance with Section 8.11.

(e)           Notwithstanding the other provisions of this Section 5.3, if a third party asserts (other than by means of a lawsuit) that any Buyer Indemnified Party is liable to such third party for a monetary or other obligation which may constitute or result in Damages for which a Buyer Indemnified Party may be entitled to indemnification pursuant to this Article V, and the Buyer reasonably determines that it has a valid business reason to fulfill such obligation, then (i) the Buyer shall be entitled to satisfy such obligation, without prior notice to or consent from the Company Equityholder Representative or the Company Equityholders, (ii) the Buyer may subsequently make a claim for indemnification in accordance with the provisions of this Article V, and (iii) the Buyer shall be reimbursed, in accordance with the provisions of this Article V, for any such Damages for which it is entitled to indemnification pursuant to this Article V (subject to the right of the Company Equityholder Representative, on behalf of the Company Equityholders, to dispute the applicable Buyer Indemnified Party’s entitlement to indemnification, or the amount for which it is entitled to indemnification, under the terms of this Article V).

(f)            Notwithstanding anything else in this Agreement, and subject to the limitations of Section 5.5, the Buyer shall have the right, but not the obligation, to set off, in whole or in part, against any Contingent Consideration that is or may become payable pursuant to this Agreement, amounts owed or claimed in good faith to be owed by such Company Equityholder to any Buyer Indemnified Party pursuant to this Agreement and set forth in a Claim Notice pursuant to this Article V.  If the final amount of Damages in respect of such Claim Notice is determined in accordance with this Article V to be less than the amount withheld from such Contingent Consideration pursuant to this Section 5.3(f), then no later than twenty (20) calendar days following such finalization the Buyer shall deliver to the Exchange and Paying Agent for the benefit of the Company Stockholders, and the Surviving Entity or the Exchange and Paying Agent, as applicable, for the benefit of holders of Company Options, either (A) a number of shares of Buyer Common Stock equal to the applicable amount divided by the Buyer Post-Closing Stock Price corresponding to the applicable Contingent Consideration, or (B) if the issuance of such shares of Buyer Common Stock pursuant to this Section 5.3(f), together with all other issuances of Buyer Common Stock pursuant to this Agreement prior to such date, would cause the Share Cap to be exceeded, pay such excess amount in cash to the Exchange and Paying Agent or the Surviving Entity, as applicable, for prompt distribution to the Company Equityholders in accordance with Section 2.7 and the applicable Post-Closing Disbursement Certificate; provided, that the “determination date” for purposes of determining the Buyer Post-Closing Stock Price under this Section 5.3(f) shall be the date the final amount of Damages in respect of the applicable Claim Notice is determined pursuant to this Article V.

54

(g)           Without limitation of Section 2.4, the Company Equityholder Representative shall have full power and authority on behalf of each Company Equityholder (as an Indemnifying Party and an Indemnified Party) to take any and all actions on behalf of, execute any and all instruments on behalf of, and execute or waive any and all rights of, the Company Equityholders under this Article V.  The Company Equityholder Representative shall have no liability to any Company Equityholders for any action taken or omitted on behalf of the Company Equityholders pursuant to this Article V.

(h)           Notwithstanding anything to the contrary in this Agreement, for purposes of determining (i) whether there has been a breach of any representation or warranty set forth in Article III and (ii) the amount of Damages for which any Buyer Indemnified Party may be entitled to indemnification under this Article V, each such representation or warranty (other than the representations and warranties set forth in clause (b) of Section 3.5 and clause (a) of Section 3.6) shall be deemed to have been made without any qualifications or limitations as to materiality (including any qualifications or limitations made by reference to a Company Material Adverse Effect or Buyer Material Adverse Effect, as applicable).

COVENANTS

For the avoidance of doubt, any costs, expenses, liabilities or other amounts owed or payable with respect to such “tail policy” that remain unpaid as of the Closing shall be deemed to be “Company Transaction Expenses” for all purposes hereunder.  In the event the Company or the Surviving Entity or any of their respective successors or assigns (i) consolidates with or merges into any other Person and shall not be the continuing or surviving corporation or entity of such consolidation or merger or (ii) transfers all or substantially all of its properties and assets to any Person, then, and in each such case, the Buyer shall ensure that the successors and assigns of the

58

Company or the Surviving Entity, as the case may be, or at the Buyer’s option, Buyer, shall assume the obligations set forth in this Section 6.1.

6.2          Tax Matters.

(a)           Preparation and Filing of Tax Returns; Payment of Taxes.

(i)            The Buyer, at its expense, shall prepare and timely file or shall cause to be prepared and timely filed all Tax Returns for the Company for Pre-Closing Tax Periods that are due after the Closing Date (“Buyer Prepared Returns”), and subject to Buyer’s rights to indemnification for Pre-Closing Taxes, Buyer shall timely pay any Taxes shown on such Tax Returns.  Buyer Prepared Returns, including any Tax Return of the Company to be prepared and filed for taxable periods beginning on or before the Closing Date and ending after the Closing Date (a “Straddle Period”), shall be prepared on a basis consistent with the last previous similar Tax Return except as required by applicable Law. In the case of any Buyer Prepared Return that (1) is the final income Tax Return of the Company or (2) shows Taxes for which the Company Equityholders are required to indemnify the Buyer under Article V, the Buyer shall provide the Company Equityholder Representative with a copy of such proposed Tax Return (and such additional information regarding such Tax Return as may reasonably be requested by the Company Equityholder Representative) for review and comment at least forty-five (45) calendar days prior to the filing of such Tax Return (or in the case of non-income Tax Returns, such period of time prior to filing as is reasonably practicable).  The Buyer shall consider in good faith any comments reasonably requested by the Company Equityholder Representative in writing and received by the Buyer prior to the filing of such Tax Return.

(ii)           All transfer, sales, use, stamp, conveyance, real property transfer, recording, registration, documentary, filing and other non-income Taxes and administrative fees (including, without limitation, notary fees) arising in connection with the consummation of the transactions contemplated by this Agreement (“Transfer Taxes”) shall be borne fifty percent (50%) by the Company Equityholders and fifty percent (50%) by Buyer.  The party required by applicable Law to file any Tax Return relating to Transfer Taxes shall be responsible for filing such Tax Return and the other party shall cooperate with the filing party in the filing of any such Tax Returns with respect to Transfer Taxes, including promptly supplying any information in its possession that is reasonably necessary to complete such Tax Returns.

(b)           Allocation of Certain Taxes.

(i)            The Buyer and the Company Equityholders agree that if the Company is permitted but not required under applicable foreign, state or local Tax Laws to treat the Closing Date as the last day of a taxable period, the Buyer and the Company Equityholders shall treat such day as the last day of a taxable period.

(ii)           The amount of any Taxes for a Straddle Period allocable to a Pre-Closing Tax Period shall be deemed to equal (i) in the case of Taxes that (x) are based upon or related to income, receipts or payroll or (y) imposed in connection with any sale or other transfer or assignment of property (other than Transfer Taxes described in Section 6.2(a)), the amount which would be payable if the taxable year ended with the Closing Date, and (ii) in the case of

59

other Taxes imposed on a periodic basis (including property Taxes), the amount of such Taxes for the entire period multiplied by a fraction the numerator of which is the number of calendar days in the period ending with the Closing Date and the denominator of which is the number of calendar days in the entire period.  For purposes of computing the Taxes attributable to the two portions of a taxable period pursuant to this Section 6.2(b)(ii), the amount of any item that is taken into account only once for each taxable period (e.g., the benefit of graduated tax rates, exemption amounts, etc.) shall be allocated between the two portions of the period in proportion to the number of calendar days in each portion.

(c)           Post-Closing Restrictions. The Buyer, the Surviving Company, and its Subsidiaries will not (and will not permit their respective Affiliates to) (i) except for Tax Returns prepared and filed in accordance with Section 6.2(a), file or amend any Tax Returns of the Company or its Subsidiaries with respect to any Pre-Closing Tax Period, (ii) with respect to Tax Returns prepared and filed in accordance with Section 6.2(a) after the date such Tax Returns are filed, amend any such Tax Returns, (iii) make or change any Tax election or change any method of accounting that has retroactive effect to the Company for a Pre-Closing Tax Period (including any election pursuant to Section 338 of the Code), or (iv) agree to extend or waive the statute of limitations with respect to Taxes of the Company or any of its Subsidiaries for a Pre-Closing Tax Period, in each such case, if such action could reasonably be expected to form the basis for a claim of indemnification against the Company Equityholders pursuant to this Agreement, except, in each case, (A) with the prior written consent of the Company Equityholder Representative (which will not be unreasonably withheld delayed or conditioned), or (B) if required by Law (provided that the Buyer shall have consulted in good faith with the Company Equityholder Representative regarding the requirements of applicable Law before taking any action pursuant to this clause (B)).

(d)           Cooperation on Tax Matters; Tax Audits.

(i)            The Buyer, the Surviving Entity and the Company Equityholder Representative and their respective Affiliates shall cooperate in the preparation of all Tax Returns and the conduct of all Tax Contests relating to the determination of any Tax for any Tax periods for which one party could reasonably require the assistance of the other party in obtaining any necessary information.

(ii)           If Buyer, the Surviving Entity or any of their Affiliates receives notice of a Tax Contest with respect to (i) the qualification of the Merger as a reorganization within the meaning of Section 368(a) of the Code or (ii) any Taxes for which the Company Equityholders are required to indemnify the Buyer under Article V, then within ten (10) Business Days after receipt of such notice, the Buyer shall notify the Company Equityholder Representative of such notice. No delay or failure in so notifying the Company Equityholder Representative shall relieve the Company Equityholders of any liability or obligation hereunder except to the extent of any damage or liability caused by or arising out of such delay or failure.

(A)          The Company Equityholder Representative may elect to control the conduct and resolution of such Tax Contest solely to the extent that such Tax Contest relates to the qualification of the Merger as a reorganization within the meaning of Section 368(a) of the Code, provided that (i) the Company Equityholder Representative shall permit Buyer to

60

participate in such Tax Contest (using counsel of its own choosing), (ii) the Company Equityholder Representative shall keep Buyer reasonably informed of all material developments on a timely basis with respect to any such Tax Contest, and (iii) the Company Equityholder Representative shall not enter into any settlement of, otherwise compromise or abandon any Tax Contest without the prior written consent of Buyer, which consent shall not be unreasonably withheld, conditioned or delayed.

(B)          With respect to any Tax Contest (1) involving Tax matters or items that could reasonably be expected to form the basis for a claim of indemnification against the Company Equityholders pursuant to this Agreement and (2) that the Company Equityholder Representative does not or cannot elect to control pursuant to the preceding Section 6.2(d)(ii)(A), Buyer will control such Tax Contest, including the defense and settlement thereof; provided, that, (i) the Buyer shall permit the Company Equityholder Representative to participate in such Tax Contest (using counsel of its own choosing), (ii) Buyer shall keep the Company Equityholder Representative reasonably informed of all material developments on a timely basis with respect to any such Tax Contest, and (iii) Buyer shall not enter into any settlement of, otherwise compromise or abandon any such Tax Contest without the prior written consent of the Company Equityholder Representative, which consent shall not be unreasonably withheld, conditioned or delayed.

(e)           Termination of Tax Sharing Agreements.  All Tax sharing agreements or similar arrangements with respect to or involving the Company shall be terminated prior to the Closing Date.

(f)            Tax Treatment.

(i)            For U.S. federal income tax purposes, the First Merger and the Second Merger are intended to be treated as integrated steps in a single transaction that together qualify as a “reorganization” within the meaning of Section 368(a) of the Code.  The parties adopt this Agreement as a “plan of reorganization” for purposes of Sections 354 and 361 of the Code and within the meaning of Sections 1.368-2(g) and 1.368-3 of the Treasury Regulations. None of the parties shall (and each of the parties shall cause their respective Subsidiaries not to) take any action, or fail to take any action, other than as expressly contemplated by this Agreement, that could reasonably be expected to prevent or impede the Merger from qualifying as such a reorganization. Buyer, Merger Subsidiaries, and the Company agree to report the Merger for U.S. federal income tax purposes as a “reorganization” within the meaning of Section 368(a) of the Code unless otherwise required by a “determination” (within the meaning of Section 1313(a) of the Code) or otherwise determined in settlement of a Tax Contest in accordance with the procedures set forth in Section 6.2(d)(ii), including attaching the statement described in Treasury Regulations Section 1.368-3(a) on or with the Company’s return of the taxable year of the Merger.  Except for the covenants in this Section 6.2(f)(i), and the last sentence of Section 4.1, it is understood and agreed that neither Buyer nor Merger Subsidiaries makes any representations or warranties to the Company Equityholders regarding the Tax treatment of the Merger.

61

(ii)           For all applicable Tax purposes, the parties to this Agreement agree to, and no party shall take any action or filing position inconsistent with, the following Tax treatment of the items specified below:

(A)          The contingent rights of the Company Equityholders to their Pro Rata Share of the Contingent Consideration in respect of their Company Stock (i) shall be treated as deferred contingent purchase price potentially eligible for installment sale treatment under Section 453 of the Code and any corresponding provision of state, local or non-U.S. Law as appropriate, and (ii) if and to the extent any such amount is released or paid in respect of Company Stock, interest may be imputed on such amount to the extent required by Section 483 or 1274 of the Code.

(B)          Any payments made in respect of Company Options held by U.S. taxpayers pursuant to this Agreement shall be treated as compensation paid by the Company as and when received by the holder thereof to whom such payment is due.

(iii)          The entirety of the Aggregate Consideration payable by Buyer to the Company Equityholders in respect of Company Stock pursuant to this Agreement (including the any Future Payments) shall be allocated to Company Stock, and none shall be allocated to the noncompetition covenants made in connection with the Merger or otherwise treated as compensation; provided, however, that any such Aggregate Consideration payable in  in respect of a Company Restricted Stock Award for which an election under Section 83(b) of the Code was not properly or timely filed may be treated as compensation.

Any party to this Agreement may give any notice or other communication hereunder using any other means (including personal delivery, messenger service, ordinary mail or electronic mail), but no such notice or other communication shall be deemed to have been duly

80

given unless and until it actually is received by the party for whom it is intended.  Any party to this Agreement may change the address to which notices and other communications hereunder are to be delivered by giving the other parties to this Agreement notice in the manner herein set forth.

8.2          Entire Agreement.  This Agreement (including the schedules and exhibits hereto and the documents and instruments referred to in this Agreement that are to be delivered at the Closing) constitutes the entire agreement among the parties to this Agreement and supersedes any prior understandings, agreements or representations by or among the parties hereto, or any of them, written or oral, with respect to the subject matter hereof; provided, that the Confidentiality Agreement shall remain in effect in accordance with its terms.

8.3          Third-Party Beneficiaries.  This Agreement is not intended to, and shall not, confer upon any other Person any rights or remedies hereunder, except that the (a) Buyer Indemnified Parties shall be third-party beneficiaries of Article V and (b) the D&O Indemnified Parties are entitled to the rights and remedies of third party beneficiaries with respect to Section 6.1, in addition to any remedy at law or in equity.

8.4          Assignment.  None of this Agreement nor any of the rights, interests or obligations under this Agreement may be transferred, assigned or delegated, in whole or in part, by operation of Law or otherwise by any of the parties hereto without the prior written consent of the other parties, and any such transfer, assignment or delegation without such prior written consent shall be null and void, except that the Buyer or the Merger Subsidiaries may, without the consent of the other parties hereto, transfer or assign its rights and obligations under this Agreement, in whole or from time to time in part, (a) to one (1) or more of their Affiliates (provided, that such transfer or assignment shall not relieve the Buyer or the Merger Subsidiaries of its primary liability for its obligations hereunder or enlarge, alter or change any obligation of any other party hereto or due to the Buyer or the Merger Subsidiaries) or (b) to any Successor Entity in accordance with Section 2.8(f), in which case, if such Successor Entity expressly agrees in writing to assume and perform the Buyer’s obligations under Section 2.8 of this Agreement and the other obligations pursuant to Section 2.8, the Buyer shall cease to have any further obligations under Section 2.8 of this Agreement.  Subject to the preceding sentence, this Agreement shall be binding upon, inure to the benefit of, and be enforceable by, the parties hereto and their respective successors and permitted assigns.  During the Payment Term, the Buyer and/or its Subsidiaries or any of their respective Affiliates shall not sell, transfer or otherwise convey to any Person (other than to an Affiliate pursuant to the first sentence of this Section 8.4) all or substantially all of its or their assets related to the Lead Compounds and Milestone Products except to the extent permitted under Section 2.8(f) of this Agreement. For the avoidance of doubt, nothing in Section 2.8(f) or this Section 8.4 shall limit the ability of the Buyer and/or its Subsidiaries or any of their respective Affiliates from selling, transferring or otherwise conveying less than substantially all of its or their assets related to the Lead Compounds and Milestone Products, other than pursuant to any of the events set forth in clause (1) or (2) of Section 2.8(h)(ix).

8.5          Severability.  Any term or provision of this Agreement that is invalid or unenforceable in any situation in any jurisdiction shall not affect the validity or enforceability of the remaining terms and provisions hereof or the validity or enforceability of the offending term

81

or provision in any other situation or in any other jurisdiction.  If the final judgment of a court of competent jurisdiction declares that any term or provision hereof is invalid or unenforceable, the parties hereto agree that the court making such determination shall have the power to limit the term or provision, to delete specific words or phrases, or to replace any invalid or unenforceable term or provision with a term or provision that is valid and enforceable and that comes closest to expressing the intention of the invalid or unenforceable term or provision, and this Agreement shall be enforceable as so modified.  In the event such court does not exercise the power granted to it in the prior sentence, the parties hereto agree to replace such invalid or unenforceable term or provision with a valid and enforceable term or provision that will achieve, to the extent possible, the economic, business and other purposes of such invalid or unenforceable term.

8.6          Counterparts and Signature.  This Agreement may be executed in two (2) or more counterparts, each of which shall be deemed an original but all of which together shall be considered one (1) and the same agreement and shall become effective when counterparts have been signed by each of the parties hereto and delivered to the other parties, it being understood that all parties need not sign the same counterpart.  This Agreement may be executed and delivered by an electronic scan delivered by electronic transmission.

8.7          Interpretation.  Except where expressly stated otherwise in this Agreement, the following rules of interpretation apply to this Agreement: (a) “either” and “or” are not exclusive and “include,” “includes” and “including” are not limiting; (b) “hereof,” “hereto,” “hereby,” “herein” and “hereunder” and words of similar import when used in this Agreement refer to this Agreement as a whole and not to any particular provision of this Agreement; (c) “date of this Agreement” refers to the date set forth in the initial caption of this Agreement; (d) “extent” in the phrase “to the extent” means the degree to which a subject or other thing extends, and such phrase does not mean simply “if”; (e) the descriptive headings and table of contents included herein are included for convenience only and shall not affect in any way the meaning or interpretation of this Agreement or any provision hereof; (f) definitions contained in this Agreement are applicable to the singular as well as the plural forms of such terms; (g) references to a contract or agreement mean such contract or agreement as amended or otherwise supplemented or modified from time to time; (h) references to a Person are also to its permitted successors and assigns; (i) references to an “Article,” “Section,” “Exhibit” or “Schedule” refer to an Article or Section of, or an Exhibit or Schedule to, this Agreement; (j) references to “$” or otherwise to dollar amounts refer to the lawful currency of the United States; and (k) references to a federal, state, local or foreign Law include any rules, regulations and delegated legislation issued thereunder; and (l) references to accounting terms used and not otherwise defined herein have the meaning assigned to them under GAAP.  When reference is made in this Agreement to information that has been “made available” to the Buyer, that shall consist of only the information that was (i) contained in the Company’s electronic data room no later than 5:00 p.m., Eastern time, on the second (2nd) Business Day prior to the date of this Agreement or (ii) delivered to the Buyer or its counsel prior to the date of this Agreement.  The language used in this Agreement shall be deemed to be the language chosen by the parties hereto to express their mutual intent, and no rule of strict construction shall be applied against any party hereto.  No summary of this Agreement prepared by any party shall affect the meaning or interpretation of this Agreement.  If any date on which a party is required to make a payment or a delivery pursuant to the terms hereof is not a Business Day, then such party shall make such payment or delivery on the next succeeding Business Day.

82

8.8          Governing Law.  This Agreement (and any claims or disputes arising out of or related hereto or the transactions contemplated hereby or to the inducement of any party to enter herein, whether for breach of contract, tortious conduct or otherwise and whether predicated on common law, statute or otherwise) shall be governed in all respects, including validity, interpretation, and effect, by and construed in accordance with the internal Laws of the State of Delaware (including in respect of the statute of limitations or other limitations period applicable to any claim, controversy or dispute) 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.

8.9          Remedies.  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.  It is accordingly agreed that the parties shall be entitled to seek an injunction or injunctions to prevent breaches of this Agreement and to seek 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 (i) the party seeking such remedy has an adequate remedy at Law or (ii) an award of specific performance is not an appropriate remedy for any reason at Law or equity.

8.10        Confidentiality.  The parties acknowledge that the Buyer, the Company and Affiliates of the Company have previously executed the Confidentiality Agreement, which Confidentiality Agreement shall continue in full force and effect in accordance with its terms, except as expressly modified herein or in the other agreements delivered in connection with this Agreement.  The parties acknowledge and agree that the Buyer: (i) may issue a press release with respect to this Agreement and the matters contemplated hereby; (ii) intends to publicly file this Agreement with the SEC; (iii) intends to seek confidential treatment under applicable SEC rules with respect to certain matters and terms contained in this Agreement; and (iv) may make any public disclosure it believes in good faith is required by applicable Law or stock market rule, or, following the Closing, for any other reason.

8.11        Submission to Jurisdiction.  Each of the parties to this Agreement (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, (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, and (e) waives any right it may have to a trial by jury with respect to any action or proceeding arising out of or relating to this Agreement.  Each of the parties hereto waives any defense of improper venue or 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 hereto 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

83

notices in Section 8.1.  Nothing in this Section 8.11, however, shall affect the right of any party to serve legal process in any other manner permitted by Law.  Nothing in this Section 8.11 shall limit the right of a party to seek injunctive relief under Section 8.9(b) in any applicable jurisdiction.

8.12        Conflict of Interest.  If the Company Equityholder Representative so desires, acting on behalf of the Company Equityholders and without the need for any consent or waiver by the Company or Buyer, ▇▇▇▇▇▇ LLP (“Cooley”) shall be permitted to represent the Company Equityholders after the Closing solely in connection with the transactions contemplated by this Agreement, any other agreements referenced herein or any disagreement or dispute relating thereto.  Without limiting the generality of the foregoing, after the Closing, Cooley shall be permitted to represent the Company Equityholders, any of their agents and Affiliates, or any one or more of them, solely in connection with any negotiation, transaction or dispute (including any litigation, arbitration or other adversary proceeding) with the Buyer, the Company or any of their agents or Affiliates under or relating to this Agreement, any transaction contemplated by this Agreement, such as claims or disputes arising under other agreements entered into in connection with this Agreement, including with respect to any indemnification claims.

8.13        Attorney-Client Privilege.  The Buyer and the Company agree that any Covered Materials, shall belong to and be controlled by the Company Equityholder Representative, and not by the Surviving Entity, following the Closing, and may be waived only by the Company Equityholder Representative, and not the Surviving Entity, and shall not pass to or be claimed or used by the Buyer or the Surviving Entity. Absent the consent of the Company Equityholder Representative, neither the Buyer nor the Surviving Entity shall have a right to access the Covered Materials following the Closing and, in the event the Buyer or the Surviving Entity accesses Covered Materials in violation of this sentence, such access will not waive or otherwise affect the rights of the Company Equityholder Representative with respect to the related privilege or protection. Notwithstanding the foregoing, if a dispute arises between the Buyer or the Surviving Entity, on the one hand, and a third party other than (and unaffiliated with) the Company Equityholders and the Company Equityholder Representative, on the other hand, after the Closing, then the Surviving Entity may assert such attorney-client privilege to prevent disclosure of such Covered Materials; provided, further, that the Buyer and the Surviving Entity may not waive such privilege without the prior written consent of the Company Equityholder Representative (such consent not to be unreasonably withheld, conditioned or delayed).  The parties acknowledge and agree that this Section 8.13 shall not limit or otherwise prohibit the Buyer’s ability to (a) compel discovery of information that is not subject to an attorney-client privilege in the event that such information is relevant to a dispute that arises after the Closing, (ii) in the event that the Buyer or the Surviving Entity receives a subpoena or other discovery request pursuant to Law that calls for the search for, or of, documents that may include Covered Materials, comply with its legal obligations, and (iii) in the event that a dispute arises between the Buyer or the Surviving Entity and a third party other than a party to this Agreement following the Closing, the Buyer and/or the Surviving Entity may assert the attorney-client privilege to prevent disclosure of confidential communications by Cooley.

8.14        Amendment.  This Agreement may not be amended except by an instrument in writing making specific reference to this Agreement and signed on behalf of each of the parties hereto (including the Company Equityholder Representative following the Closing).
