(a) No later than 7 days prior to the Closing Date, the Company will cause to be prepared and delivered to Parent a good faith estimate of the Closing Balance Sheet and a good faith estimate of Closing Working Capital. The Company’s estimate of Closing Working Capital shall (i) accurately reflect the Working Capital of the Company as of the Closing Date, (ii) be based upon balance sheet line items and accounts of the Company calculated in accordance with GAAP applied consistently with respect to the accounting policies, practices and procedures used in the preparation of the Company Balance Sheet and (iii) otherwise be prepared in accordance with this Agreement.

(b) If Parent disagrees in good faith with any item within the Company’s estimate of Closing Working Capital delivered pursuant to Section 2.02(a), Parent may, within 3 days after delivery of the documents referred to in Section 2.02(a), deliver a notice to the Company setting forth, in reasonable detail and to the extent practicable, each item or amount so disputed by Parent, Parent’s calculation of such item or amount and Parent’s good faith estimate of Closing Working Capital. Upon delivery of any such notice, Parent shall be deemed to have agreed with all other items and amounts set forth in the estimate of Closing Working Capital delivered pursuant to Section 2.02(a) that are not specifically the subject of dispute in any notice delivered by Parent as provided above.

(c) If Parent disagrees in good faith with the Company’s estimate of Closing Working Capital, Parent and the Company shall, during the time between the delivery of such estimate and the Closing Date, use commercially reasonable efforts to reach agreement on the disputed items or amounts in order to determine the Adjusted Merger Consideration. If, during such period, Parent and the Company are unable to reach such agreement, then the Adjusted Merger Consideration shall be determined based upon the Company’s good faith estimate of Closing Working Capital as provided in Section 2.02(d) and Section 2.02(e) and the Escrow Amount shall include the difference between Adjusted Merger Consideration as calculated based on the Company’s estimate of Closing Working Capital and Adjusted Merger Consideration as calculated based on Parent’s estimate of Closing Working Capital (the “Disputed Amount”); provided, however, that in no event shall the Disputed Amount exceed $5,000,000.

(d) Following the delivery of the Company’s estimate of Closing Working Capital delivered pursuant to Section 2.02(a), “Final Working Capital” shall mean (i) Closing Working Capital as shown in the Company’s calculation delivered pursuant to Section 2.02(a), if no notice of dispute with respect thereto is duly delivered pursuant to Section 2.02(b) or (ii) if a notice of dispute is duly delivered pursuant to and in

accordance with Section 2.02(b), the amount agreed as between Parent and the Company pursuant to Section 2.02(c), if so agreed, or in the absence of such agreement, the Company’s good faith estimate of Closing Working Capital.

(e) Following the determination of Final Working Capital, the “Adjusted Merger Consideration” shall be calculated as the Unadjusted Merger Consideration (i) less the amount by which Target Working Capital exceeds Final Working Capital, if Target Working Capital is greater than Final Working Capital (it being understood and agreed that if Target Working Capital is less than Final Working Capital there shall be no corresponding adjustment to the Unadjusted Merger Consideration) and (ii) less any Additional Cash Expenses.

Section 2.03. Final Merger Consideration; Form Thereof. The consideration to be received by holders of Company Stock pursuant to this Agreement (the “Final Merger Consideration”) shall be determined as follows:

(a) If the Average Pre-Closing Parent Stock Price is greater than the Average Pre-Signing Parent Stock Price multiplied by 1.3, then the Company may elect for the Final Merger Consideration to consist of an amount of cash equal to the Adjusted Merger Consideration. In order to so elect, the Company must provide Parent with written notice of its election pursuant to this Section 2.03(a) no later than five Business Days prior to the Closing Date. In the event that the Company does not so elect as provided in the preceding sentence, then Final Merger Consideration shall consist of the number of shares of Parent Common Stock determined by dividing (i) the Adjusted Merger Consideration by (ii) the Average Pre-Closing Parent Stock Price.

(b) If the Average Pre-Closing Parent Stock Price is greater than or equal to the Average Pre-Signing Parent Stock Price but less than or equal to the Average Pre-Signing Parent Stock Price multiplied by 1.3, then the Final Merger Consideration shall consist of the number of shares of Parent Common Stock determined by dividing (i) the Adjusted Merger Consideration by (ii) the Average Pre-Closing Parent Stock Price.

(c) If the Average Pre-Closing Parent Stock Price is less than the Average Pre-Signing Parent Stock Price but greater than or equal to the Average Pre-Signing Parent Stock Price multiplied by 0.7, then the Final Merger Consideration shall consist of:

     (i) An amount of cash equal to the lesser of:

     (A) The amount determined by multiplying (x) the Adjusted Merger Consideration by (y) one minus the amount determined by dividing the Average Pre-Closing Parent Stock Price by the Average Pre-Signing Parent Stock Price; and

     (B) The maximum amount of cash that (1) in the reasonable judgment of Parent’s counsel, will allow Parent’s counsel to render the tax opinion referred to in Section 9.02(f) and (2) in the reasonable

12

judgment of the Company’s counsel, will allow the Company’s counsel to render the tax opinion referred to in Section 9.03(c); and

     (ii) The number of shares of Parent Common Stock determined by dividing (A) the Adjusted Merger Consideration less the amount of cash determined pursuant to Section 2.03(c)(i) above by (B) the Average Pre-Closing Parent Stock Price.

(d) If the Average Pre-Closing Parent Stock Price is less than the Average Pre-Signing Parent Stock Price multiplied by 0.7, then the Final Merger Consideration shall consist of an amount of cash equal to the Adjusted Merger Consideration.

In each case in which the Final Merger Consideration includes shares of Parent Common Stock, the Final Merger Consideration shall include any cash delivered in lieu of fractional shares of Parent Common Stock pursuant to Section 2.10.

Section 2.04. The Merger. (a) At the Effective Time, Merger Subsidiary shall be merged with and into the Company in accordance with California Law, whereupon the separate existence of Merger Subsidiary shall cease, and the Company shall be the surviving corporation (the “Surviving Corporation”).

(b) As soon as practicable after satisfaction or, to the extent permitted hereunder, waiver of all conditions to the Merger, the Company and Merger Subsidiary will file an agreement of merger in customary form with the Secretary of State of the State of California and make all other filings or recordings required by California Law in connection with the Merger. Immediately prior to the filing of the agreement of merger, a closing (the “Closing”) will be held at the offices of Davis Polk & Wardwell, 1600 El Camino Real, Menlo Park, California 94025 (or such other place as the parties may agree). The Merger shall become effective at such time (the “Effective Time”) as the agreement of merger is duly filed with the Secretary of State of the State of California or at such later time as is specified in the agreement of merger.

(c) From and after the Effective Time, the Merger shall have the effect set forth under California Law, and without limiting the foregoing, from and after the Merger, the Surviving Corporation shall succeed without transfer to all rights and properties of the Company and Merger Subsidiary, and shall be subject to the debts and liabilities of the Company and Merger Subsidiary as if the Surviving Corporation had incurred such debts and liabilities, all as provided under California Law.

Section 2.05. Conversion of Shares. At the Effective Time:

(a) except as otherwise provided in Section 2.05(b), each share of Company Common Stock and Company Preferred Stock outstanding immediately prior to the Effective Time (which shares of Company Preferred Stock shall be deemed to have converted into Company Common Stock pursuant to Article IV.3(c) of the Company’s articles of incorporation) shall be converted into the right to receive (i) the number of

shares of Parent Stock, if any, equal to the Stock Exchange Ratio and (ii) an amount of cash, if any, equal to the Cash Exchange Ratio;

(b) each share of Company Stock held by the Company as treasury stock or owned by Parent or any of its Subsidiaries immediately prior to the Effective Time shall be canceled, and no payment shall be made with respect thereto; and

(c) each share of common stock of Merger Subsidiary outstanding immediately prior to the Effective Time shall be converted into and become one share of common stock of the Surviving Corporation with the same rights, powers and privileges as the shares so converted and shall constitute the only outstanding shares of capital stock of the Surviving Corporation.

(d) if any shares of Company Stock outstanding immediately prior to the Effective Time are unvested or are subject to a repurchase option, risk of forfeiture or other condition under any applicable restricted stock purchase agreement or other agreement with the Company, then, at Parent’s option and in Parent’s sole discretion, the Final Merger Consideration in respect of such shares shall either be (i) paid to the holder thereof, in the manner provided in Section 2.06, without restriction or (ii) paid to the holder thereof over time upon satisfaction of the vesting requirements associated with the applicable restricted stock schedule.

Notwithstanding the foregoing, the parties acknowledge and agree that the Escrow Amount shall be deducted from the Final Merger Consideration payable to holders of Company Stock pursuant to this Article 2, and shall only be payable (x) upon release from the Escrow Account in accordance with this Agreement and the Escrow Agreement and (y) to the extent not reduced by indemnification payments pursuant to Article 10.

Section 2.06. Surrender and Payment. (a) Parent will appoint an exchange agent (the “Exchange Agent”) for the purpose of exchanging certificates representing the shares of Company Stock (the “Certificates”) for the Final Merger Consideration payable in respect of the shares of Company Stock evidenced by each such Certificate (less the Escrow Holdback). Immediately following the Effective Time, Parent will make available the Final Merger Consideration (less the Escrow Amount) to be paid in respect of the Certificates.

(b) Each holder of outstanding Company Stock that has been converted into the right to receive the Final Merger Consideration will be entitled to receive, upon surrender to the Exchange Agent of a Certificate, together with a properly completed letter of transmittal (which shall specify that the delivery shall be effected, and risk of loss and title shall pass, only upon proper delivery of the Certificate to the Exchange Agent), the Final Merger Consideration less the Escrow Holdback issuable and/or payable for each share of Company Stock represented by such Certificate. Until so surrendered, from and after the Effective Time each such Certificate shall represent for all purposes only the right to receive such Final Merger Consideration.

(c) If any portion of the Final Merger Consideration is to be paid to a Person other than the Person in whose name the surrendered Certificate is registered, it shall be a condition to such payment that the Certificate so surrendered shall be properly endorsed or otherwise be in proper form for transfer and that the Person requesting such payment shall pay to the Exchange Agent any transfer or other taxes required as a result of such payment to a Person other than the registered holder of such Certificate or establish to the satisfaction of the Exchange Agent that such tax has been paid or is not payable.

(d) After the Effective Time, there shall be no further registration of transfers of shares of Company Stock. If, after the Effective Time, Certificates are presented to the Surviving Corporation, they shall be canceled and exchanged for the Final Merger Consideration provided for, and in accordance with the procedures set forth, in this Article 2.

(e) Any portion of the Final Merger Consideration made available to the Exchange Agent pursuant to Section 2.06(a) (and any interest or other income earned thereon) that remains unclaimed by the holders of shares of Company Stock ninety (90) Business Days after the Effective Time shall be returned to Parent, upon demand, and any such holder who has not exchanged shares of Company Stock for the Final Merger Consideration issuable and/or payable in respect of such shares of Company Stock (less the Escrow Holdback applicable thereto) in accordance with this Section 2.06 prior to that time shall thereafter look only to Parent for payment of the Final Merger Consideration issuable and/or payable in respect of such shares of Company Stock without any interest thereon. Notwithstanding the foregoing, Parent shall not be liable to any holder of shares of Company Stock for any amount paid to a public official pursuant to applicable abandoned property, escheat or similar laws. Immediately prior to such time when amounts remaining unclaimed by holders of shares of Company Stock would otherwise escheat to or become property of any governmental authority, such unclaimed amounts shall become, to the extent permitted by applicable law, the property of Parent free and clear of any claims or interest of any Persons previously entitled thereto.

(f) Any portion of the Final Merger Consideration made available to the Exchange Agent pursuant to Section 2.06(a) to pay for shares of Company Stock for which appraisal rights have been perfected shall be returned to Parent, upon demand.

Section 2.07. Dissenting Shares. Notwithstanding Section 2.05, shares of Company Stock outstanding immediately prior to the Effective Time and held by a holder who has not voted in favor of the Merger or consented thereto in writing and who has demanded appraisal for such shares in accordance with California Law shall not be converted into a right to receive the Final Merger Consideration issuable and/or payable in respect of such shares of Company Stock, but the holder thereof shall be entitled only to such rights as are provided by California Law, unless such holder fails to perfect, withdraws or otherwise loses its right to appraisal. If, after the Effective Time, such holder fails to perfect, withdraws or loses its right to appraisal, such shares shall be treated as if they had been converted as of the Effective Time into a right to receive the Final Merger Consideration issuable and/or payable in respect of such shares of Company Stock less the Escrow Holdback applicable thereto. The Company shall give Parent

prompt notice of any demands received by the Company for appraisal of shares of Company Stock, and Parent shall have the right to participate in all negotiations and proceedings with respect to such demands. Except with the prior written consent of Parent, the Company shall not make any payment with respect to, or settle or offer to settle, any such demands.

Section 2.08. Stock Options. (a) All Company Employee Stock Options and Supplemental Options shall, at the Effective Time and by virtue of the Merger and without any action on the part of the holder thereof, be assumed by Parent. Each Company Employee Stock Option and Supplemental Option so assumed by Parent under this Agreement shall continue to have, and be subject to, substantially similar terms and conditions to those set forth in the Company Stock Option Plan or as provided in the respective option agreement immediately prior to the Effective Time (including the vesting schedule), except that (i) each Company Employee Stock Option and Supplemental Option will be exercisable for that number of whole shares of Parent Common Stock equal to the product of (A) the number of shares of Company Common Stock that were issuable upon exercise of such Company Employee Stock Option or Supplemental Option immediately prior to the Effective Time multiplied by (B) the Option Exchange Ratio, rounded down to the nearest whole number of shares of Parent Common Stock; and (ii) the per share exercise price for the shares of Parent Common Stock issuable upon exercise of such assumed Company Employee Stock Option or Supplemental Option will be equal to the quotient determined by dividing (A) the exercise price per share of Company Common Stock at which such Company Employee Stock Option or Supplemental Option was exercisable immediately prior to the Effective Time by (B) the Option Exchange Ratio, rounded up to the nearest whole cent. It is the intention of the parties hereto that the Company Employee Stock Options and Supplemental Options assumed by Parent following the Effective Time pursuant to this Section will, to the extent permitted by applicable law, qualify as incentive stock options as defined in Section 422 of the Code, to the extent any such Company Employee Stock Options or Supplemental Options qualified as incentive stock options immediately prior to the Effective Time.

(b) As soon as practicable after the Effective Time, Parent shall deliver to each holder of an outstanding Company Employee Stock Option or Supplemental Option an appropriate notice setting forth such holder’s rights pursuant thereto. Prior to the Closing, Parent shall take all corporate action necessary to reserve for issuance a sufficient number of shares of Parent Common Stock for delivery upon exercise of assumed Company Employee Stock Options and Supplemental Options pursuant to the terms set forth in this Section.

(c) At the Effective Time, all Company Stock Options that are not Company Employee Stock Options shall accelerate in accordance with their terms and, to the extent not exercised, terminate in accordance with their terms. The Company shall provide notice to holders of such Company Stock Options in accordance with the terms of the Company Stock Option Plan.

Section 2.09. Adjustments. If, during the period between the date of this Agreement and the Effective Time, any change in the outstanding shares of Company Stock or Parent Common Stock shall occur, including by reason of any reclassification, recapitalization, stock split or combination, exchange or readjustment of shares of Company Stock or Parent Common Stock, or stock dividend thereon with a record date during such period, the Final Merger Consideration, the Escrow Holdback, and any other amounts payable pursuant to this Agreement shall, to the extent necessary, be appropriately adjusted.

Section 2.10. Fractional Shares. No fractional shares of Parent Stock shall be issued in the Merger. All fractional shares of Parent Stock that a holder of shares of Company Common Stock would otherwise be entitled to receive as a result of the Merger shall be aggregated and if a fractional share results from such aggregation, such holder shall be entitled to receive, in lieu thereof, an amount in cash without interest determined by multiplying the Average Pre-Closing Parent Stock Price by the fraction of a share of Parent Stock to which such holder would otherwise have been entitled.

Section 2.11. Withholding Rights. Each of the Surviving Corporation and Parent shall be entitled to deduct and withhold from the consideration otherwise payable to any Person pursuant to this Article 2 such amounts as it is required to deduct and withhold with respect to the making of such payment under any provision of federal, state, local or foreign tax law. If the Surviving Corporation or Parent, as the case may be, so withholds amounts, such amounts shall be treated for all purposes of this Agreement as having been paid to the holder of the shares of Company Stock in respect of which the Surviving Corporation or Parent, as the case may be, made such deduction and withholding.

Section 2.12. Escrow. At the Effective Time, Parent shall withhold from the Final Merger Consideration otherwise issuable and/or payable in connection with the Merger an aggregate number of shares of Parent Common Stock and/or an aggregate amount of cash equal to the Escrow Amount, in the same relative proportions as the proportions of Parent Common Stock and cash that comprise the Final Merger Consideration. Prior to or simultaneously with the Effective Time, the Shareholders’ Representative and Parent shall enter into an escrow agreement (the “Escrow Agreement”) with an escrow agent selected by Parent and reasonably acceptable to the Shareholders’ Representative (the “Escrow Agent”) in the form of Exhibit C hereto. Pursuant to the terms of the Escrow Agreement, at the Effective Time Parent shall deposit the Escrow Amount into an escrow account, which account is to be managed by the Escrow Agent (the “Escrow Account”). Distributions of any shares of Parent Common Stock and/or cash from the Escrow Account shall be governed by the terms and conditions of this Agreement and the Escrow Agreement (the shares of Parent Common Stock and cash, if any, in the Escrow Account being referred to as the “Escrow Fund”). The Escrow Amount shall be withheld from, and allocated to, each holder of Company Stock based on such holder’s Escrow Holdback. All distributions from the Escrow Fund shall be made in shares of Parent Common Stock and/or cash in the same relative proportions as originally included in the Escrow Amount.

Section 2.13. Resolution of Disputed Amount. (a) In the event that any Disputed Amount is included in the Escrow Amount, Parent and the Shareholders’ Representative shall, during the 15 days following the Closing Date, use commercially reasonable efforts to reach agreement on the disputed items or amounts. If Parent and the Shareholders’ Representative are unable to reach agreement during such period, they shall promptly thereafter cause independent accountants of nationally recognized standing reasonably satisfactory to Parent and the Shareholders’ Representative (who shall not have any material relationship with Parent, the Company, the Shareholders’ Representative or any of their respective Affiliates) (the “Independent Accountants”), promptly to review the disputed items or amounts for the purpose of calculating Closing Working Capital (the “Independent Accountants’ Working Capital”). In calculating Independent Accountant’ Working Capital, such Independent Accountants shall consider only those items or amounts in the calculation of Closing Working Capital as to which Parent has disagreed pursuant to and in accordance with Section 2.02(b) . Such Independent Accountants shall deliver to Parent and the Shareholders’ Representative, as promptly as practicable (and in any event within 30 days following receipt of all information requested from the Company to calculate Closing Working Capital), a report that explains any discrepancies between such Independent Accountants’ Working Capital and Final Working Capital and sets forth the Independent Accountants’ calculation of Independent Accountants’ Working Capital. Such report and the calculations set forth therein shall be final and binding upon Parent, the Shareholders’ Representative and their respective Affiliates and shall not be subject to challenge by any of the foregoing in a court of law or otherwise. The cost of such review and report shall be paid from the Escrow Fund if Independent Accountants’ Working Capital is closer to Parent’s calculation of Closing Working Capital than the Company’s estimate of Closing Working Capital.

(b) As promptly as practicable following the delivery of the Independent Accountants’ report specified above, each of Parent and the Shareholders’ Representative shall direct the Escrow Agent to make distributions from the Escrow Fund, and the Escrow Agent shall make such distributions, as follows:

(i) If Independent Accountants’ Working Capital is less than Final Working Capital, then the Escrow Agent shall distribute from the Escrow Fund (A) to Parent, an amount equal to (1) the amount of the difference between the Adjusted Merger Consideration as actually determined pursuant to Section 2.02(e) above and the Adjusted Merger Consideration that would have resulted had such amount been calculated using Independent Accountants’ Working Capital in lieu of Final Working Capital plus (2) the cost of the Independent Accountants’ review and report pursuant to Section 2.13(a) and (B) to the former shareholders of the Company (in proportion to each such shareholder’s Escrow Holdback), the balance, if any, of the Disputed Amount that remains in the Escrow Fund following the distributions specified in clause (A) of this Section 2.13(b)(i); and

(ii) (A) If Independent Accountants’ Working Capital is greater than or equal to Final Working Capital, then the Escrow Agent shall distribute the Disputed Amount from the Escrow Fund to the former shareholders of the

Company (in proportion to each such shareholder’s Escrow Holdback) and (B) in the event that Independent Accountants’ Working Capital is greater than Final Working Capital, Parent shall issue and/or pay to the former shareholders of the Company (in proportion to each such shareholder’s Escrow Holdback), the number of shares of Parent Common Stock and/or cash not already included in the Disputed Amount that would have been issued and/or paid to such former shareholders if the Independent Accountants’ Working Capital had been the Final Working Capital at the Closing; provided, however, that in no event shall the amounts distributed to the former shareholders of the Company pursuant to this Section 2.13(b)(ii), when aggregated with the Final Merger Consideration, exceed the Unadjusted Merger Consideration.

For purposes of calculating the number of shares of Parent Common Stock to be included in a distribution of a given amount pursuant to this Section 2.13(b), Parent Common Stock shall be ascribed the same value given to it in connection with the calculation of Final Merger Consideration.

Section 2.14. Lost Certificates. If any Certificate shall have been lost, stolen or destroyed, upon the making of an affidavit of that fact by the Person claiming such Certificate to be lost, stolen or destroyed and, if required by the Surviving Corporation, the entry by such Person into an indemnification agreement in form satisfactory to Parent, or the posting by such Person of a bond, in such reasonable amount as the Surviving Corporation may direct, as indemnity against any claim that may be made against it with respect to such Certificate, the Exchange Agent will pay, in exchange for such lost, stolen or destroyed Certificate, the Final Merger Consideration issuable and/or payable in respect of the shares of Company Stock evidenced by such Certificate (less the Escrow Holdback applicable thereto), as contemplated by this Article 2.

ARTICLE 3

Section 3.01. Articles of Incorporation.

Each Parent Indemnified Party shall use commercially reasonable efforts to collect any amounts available under insurance coverage for any Damages payable under this Section 10.02.

(h) In the event Parent becomes aware of a third-party claim that Parent believes may result in an indemnification claim against the Escrow Fund by or on behalf of an Parent Indemnified Party, Parent shall promptly notify the Shareholders’ Representative of such third-party claim. Parent shall have the right in its sole discretion to conduct the defense of and to settle any such claim and the costs and expenses incurred by Parent in connection with such defense or settlement shall be included in the Damages for which any Parent Indemnified Party may seek indemnification pursuant to a claim made hereunder. The Shareholders’ Representative shall have the right to receive copies of all pleadings, notices and communications with respect to the third-party claim to the extent that receipt of such documents does not affect any privilege relating to any Parent Indemnified Party and shall be entitled, at its expense, to participate in, but not to determine or conduct, any defense of the third-party claim or settlement negotiations with respect to the third-party claim. Notwithstanding anything to the contrary set forth herein, except with the consent of the Shareholders’ Representative, no settlement of any

such claim with any third-party claimant shall in and of itself be determinative of the existence of any right to indemnification hereunder or the existence or amount of Damages relating to such matter. In the event that the Shareholders’ Representative has consented to any such settlement, neither the Shareholders’ Representative nor any former shareholders of the Company shall be entitled to object under any other provision of this Article 10 to the amount of any claim by or on behalf of any Parent Indemnified Party against the Escrow Fund for indemnity with respect to such settlement.

(i) The representations and warranties (as modified by the Company Disclosure Schedule) and the covenants and agreements of the Company, and the rights and remedies that may be exercised by the Parent Indemnified Parties, shall not be limited or otherwise affected by or as a result of any information furnished to, or any investigation made by or Knowledge of, and Parent Indemnified Party.

(j) The indemnification provided by this Article shall be the sole and exclusive remedy available to Parent and Merger Subsidiary after the Effective Time for any claim related to this Agreement or the transactions contemplated hereby, except with respect to claims arising out of fraud, criminal activity or the willful breach of covenants by a party hereto, which shall not be subject to the Deductible and shall be recoverable from the first dollar.

Section 10.03. Shareholders’ Representative. (a) Effective upon and by virtue of the vote of the holders of Company Stock approving and adopting this Agreement and the Merger, and without any further act of any of the holders of the Company Stock, the Shareholders’ Representative shall be hereby appointed as the representative of the holders of Company Stock and as the attorney-in-fact and agent for and on behalf of each holder of Company Stock solely with respect to (i) any claims by any Parent Indemnified Party against the Escrow Fund under Articles 2 and 10 of this Agreement and (ii) any amendments to the Escrow Agreement; provided, however, that any amendment of the Escrow Agreement that shall adversely affect the rights or obligations of any shareholder under the Escrow Agreement (other than any change affecting all holders of Company Stock similarly) shall require the prior written consent of such adversely affected shareholder. The Shareholders’ Representative hereby accepts such appointment. The Shareholders’ Representative shall have the authority to take any and all actions and make any decisions required or permitted to be taken by the Shareholders’ Representative under the Escrow Agreement and this Agreement, including the exercise of the power to (i) agree to, negotiate, enter into settlements and compromises of, commence any suit, action or proceeding, and comply with orders of courts with respect to, claims by any Parent Indemnified Party against the Escrow Fund under Articles 2 and 10 of this Agreement, (ii) litigate, resolve, settle or compromise any dispute that may arise pursuant to Section 5 of the Escrow Agreement, and (iii) take all actions necessary in the judgment of the Shareholders’ Representative for the accomplishment of the foregoing. The Shareholders’ Representative will have sole authority and power to act on behalf of each former shareholder of the Company with respect to the disposition, settlement or other handling of all claims against the Escrow Fund under this Agreement and all related rights or obligations of the former shareholders of the Company arising under this Agreement. The Shareholders’ Representative will also have sole authority and power to

act on behalf of each former shareholder of the Company with respect to any amendments to the Escrow Agreement. The Shareholders’ Representative shall use commercially reasonable efforts, based on contact information available to the Shareholders’ Representative, to keep the former shareholders of the Company reasonably informed with respect to actions of the Shareholders’ Representative pursuant to the authority granted the Shareholders’ Representative under this Agreement. Each former shareholder of the Company shall promptly provide written notice to the Shareholders’ Representative of any change of address of such shareholder.

(b) In all matters relating to the disposition, settlement or other handling of claims against the Escrow Fund under this Agreement or any amendments to the Escrow Agreement, the Shareholders’ Representative (or his or her successor) shall be the only party entitled to assert the rights of the former shareholders of the Company. A decision, act, consent or instruction of the Shareholders’ Representative hereunder shall constitute a decision, act, consent or instruction of all former holders of Company Stock and shall be final, binding and conclusive upon each of such shareholders, and the Escrow Agent and Parent may rely upon any such decision, act, consent or instruction of the Shareholders’ Representative as being the decision, act, consent or instruction of each and every such holder of Company Stock. The Escrow Agent and Parent shall be relieved from any liability to any Person for any acts done by them in accordance with such decision, act, consent or instruction of the Shareholders’ Representative.

(c) The Shareholders’ Representative shall have the right to recover from the Escrow Fund, prior to any distribution to the holders of Company Stock (but after any disbursement from the Escrow Fund to the Escrow Agent pursuant to terms and conditions of the Escrow Agreement), the Shareholders’ Representative’s reasonable out-of-pocket expenses incurred in serving in that capacity (the “Shareholders’ Representative’s Expenses”). In the event the Escrow Property is insufficient to satisfy the Shareholders’ Representative’s Expenses, then each holder of Company Stock will be obligated to pay a percentage of the Shareholders’ Representative’s Expenses in excess of the Escrow Fund proportionate to that holder’s Escrow Holdback.

(d) The Shareholders’ Representative will incur no liability with respect to any action taken or suffered by any party in reliance upon any notice, direction, instruction, consent, statement or other document believed by such Shareholders’ Representative to be genuine and to have been signed by the proper person (and shall have no responsibility to determine the authenticity thereof), nor for any other action or inaction, except his own gross negligence, bad faith or willful misconduct. In all questions arising under this Agreement or the Escrow Agreement, the Shareholders’ Representative may rely on the advice of outside counsel, and the Shareholders’ Representative will not be liable to anyone for anything done, omitted or suffered in good faith by the Shareholders’ Representative based on such advice.

(e) The holders of Company Stock shall severally but not jointly indemnify the Shareholders’ Representative and hold the Shareholders’ Representative harmless against any loss, liability or expense incurred without gross negligence, bad faith or willful misconduct, to the extent permitted by applicable law, on the part of the Shareholders’

Representative and arising out of or in connection with the acceptance or administration of the Shareholders’ Representative’s duties hereunder, including the reasonable fees and expenses of any legal counsel retained by the Shareholders’ Representative.

(f) At any time during the term of the Escrow Agreement, a majority-in-interest of holders of any amounts then held in the Escrow Fund may, by written consent, appoint a new representative as the Shareholders’ Representative. Notice together with a copy of the written consent appointing such new representative and bearing the signatures of holders of a majority-in-interest of those holders must be delivered to Parent and the Escrow Agent not less than ten (10) calendar days prior to such appointment. Such appointment will be effective upon the later of the date indicated in the consent or the date such consent is received by Parent and the Escrow Agent.

(g) In the event that the Shareholders’ Representative becomes unable or unwilling to continue in his or its capacity as Shareholders’ Representative, or if the Shareholders’ Representative resigns as a Shareholders’ Representative, a majority-in-interest of the holders of any amounts then held in the Escrow Fund may, by written consent, appoint a new representative as the Shareholders’ Representative. Notice and a copy of the written consent appointing such new representative and bearing the signatures of the holders of a majority-in-interest of such holders must be delivered to Parent and the Escrow Agent. Such appointment will be effective upon the later of the date indicated in the consent or the date such consent is received by Parent and the Escrow Agent.
