(a) Cash/Holdback Payment. As promptly as practicable after the Closing, but in no event later than 15 days following the Closing, Parent shall review the Estimated Cash Amount, the Estimated Working Capital Amount, and the Estimated MDA Liabilities provided to Parent by the Company prior to the Effective Time of the Merger under Section 5.12 of the Merger Agreement. In addition, Parent shall review the books and records of the Company as of the Closing Date. In the event that Parent shall have any grounds to believe, in its sole and absolute discretion, that one or more of the following facts may be true, Parent shall have no further obligation under this Section 2.4(a) and Parent shall proceed to Section 2.4(b):

(i) the Closing Cash Amount is less than the Estimated Cash Amount,

(ii) the Working Capital Amount as of the Closing Date is less than 80% of the Base Working Capital Amount, or

(iii) the MDA Liabilities as of the Closing Date are greater than the Estimated MDA Liabilities.

However, in the event that Parent believes, in its sole and absolute discretion, that (i) the Closing Cash Amount is greater than or equal to the Estimated Cash Amount, (ii) the Working Capital Amount as of the Closing Date is greater than or equal to 80% of the Base Working Capital Amount and (iii) the MDA Liabilities as of the Closing Date are less than or equal to the Estimated MDA Liabilities, then Parent shall pay or cause to be paid as promptly as practicable the Cash/Holdback Payment Amount. Notwithstanding the foregoing, in the event that, Parent shall determine through the procedures and during the time periods set forth in Section 2.4(b) that any of the facts set forth in (i), (ii) or (iii) of the immediately preceding sentence are not true and accurate in all respects, then Parent shall be entitled to offset the amount of any final discrepancy against any Earnout Payment Amount required to be made under Section 2.4(c).

(b) Closing Balance Sheet Payment.

(i) As promptly as practicable after the Closing, but in no event later than 45 days following the Closing, Parent shall provide the Stockholders’ Agent a Closing Balance Sheet, together with schedules calculating the Closing Cash Amount, the Working Capital Amount and the MDA Liabilities as of the Closing Date (the “Balance Sheet Report”), together with schedules and any supporting information with respect thereto reasonably requested by the Stockholders’ Agent. If a Dispute Notice (as defined below) is not delivered pursuant to Section 2.4(b)(iii) below, then in no event later than 60 days following the Closing, Parent shall pay or cause to be paid the Closing Balance Sheet Payment Amount, provided, however, that if the Parent has previously paid or cause to be paid the Cash/Holdback Payment Amount pursuant to Section 2.4(a), then Parent shall not be obligated to pay the Closing Balance Sheet Payment Amount.

(ii) Parent shall keep at its principal place of business full, clear and accurate books and records with respect to the Business. The books and records shall be maintained in such a manner that the Closing Cash Amount, the Working Capital Amount and the MDA Liabilities shall be readily verifiable. All books and records with respect to the Business shall be available for inspection by the Stockholders’ Agent or any attorney or accountant engaged by the Stockholders’ Agent to act on behalf of the Holders, in all cases upon reasonable prior notice and during normal business hours. The information contained in the books and records of Parent with respect to the Business shall remain confidential. If the Stockholders’ Agent does not deliver to Parent a Dispute Notice (as defined below) as set forth in Section 2.4(b)(iii) below, then the Balance Sheet Report shall be deemed final and binding and neither the Stockholders’ Agent nor the Holders shall have any further right to contest the report, the computation of the Closing Cash Amount, the Working Capital Amount or the MDA Liabilities.

(iii) In the event that the Stockholders’ Agent shall dispute the information set forth by Parent in the Balance Sheet Report or, if based on the Stockholders’ Agent’s review of the books and records of the Business in accordance with subsection (b)(ii) above, omitted from the Balance Sheet Report, as the case may be, then, within 60 calendar days following the date of the delivery by Parent of such report, the Stockholders’ Agent shall provide written notice to Parent (the “Dispute Notice”) specifying the amount disputed and the basis for the dispute, together with supporting documentation reflecting the analysis of and justification for any recomputation made. Parent and the Stockholders’ Agent shall make good faith efforts to resolve the dispute through negotiations for a period of 30 calendar days following the receipt of the written notice defining and describing the nature of the dispute. In the event that the parties are unable to finally resolve the dispute within such 30 calendar-day period, the parties to the dispute may elect by mutual agreement to extend the period of negotiation and may elect by mutual agreement to engage a mediator to assist in such negotiation. To the extent that any matter remains unresolved (as determined by notice by any party to the other parties) following negotiations, the Stockholders’ Agent and Parent shall jointly select an independent accountant of recognized

national standing to resolve any remaining disagreements, which independent accountant shall not have provided services to the Stockholders’ Agent, the Company or Parent or its affiliates during the five-year period preceding the date of its selection (the “Balance Sheet Independent Accountant”). The Stockholders’ Agent and Parent shall use their respective commercially reasonable efforts to cause such Balance Sheet Independent Accountant to make its determination within 60 calendar days of accepting its selection. Within 10 business days after the date of determination of such Balance Sheet Independent Accountant, Parent shall pay or cause to be paid to the Holders the Closing Balance Sheet Payment Amount, if any, in the manner set forth herein, provided, however, that if Parent has previously paid or cause to be paid the Cash/Holdback Payment Amount pursuant to Section 2.4(a), then Parent shall not be obligated to pay the Closing Balance Sheet Payment Amount.

(iv) The decision of the Balance Sheet Independent Accountant shall be a final, binding and conclusive resolution of the parties’ dispute as to the matter in question, shall be non-appealable, and shall not be subject to further review. Irrespective of the Balance Sheet Independent Accountant’s decision, the costs and expenses of the Balance Sheet Independent Accountant shall be split equally between the parties. In the event that the Stockholders’ Agent does not pay the full amount of one-half of the Balance Sheet Independent Accountant’s costs and expenses, Parent shall be entitled to deduct the difference between one-half of the costs and expenses of the Balance Sheet Independent Accountant and the amount actually paid by the Stockholders’ Agent to the Balance Sheet Independent Accountant from the Closing Balance Sheet Payment Amount (or, in the event that Parent has previously paid or caused to be paid the Cash/Holdback Payment Amount pursuant to Section 2.4(a), then Parent shall be entitled to offset such expenses against any Earnout Payment Amount required to be made under Section 2.4(c)). Notwithstanding the foregoing, in any case, the parties shall be responsible for the payment of their respective costs and expenses, including any attorneys’ and accountants’ fees (other than any accountants’ fees payable to the Balance Sheet Independent Accountant) incurred in connection with the dispute.

(i) As promptly as practicable after the end of the Earnout Period, but in no event later than 60 days following December 31, 2005, Parent shall provide the Stockholders’ Agent with a report, setting forth the Net Revenues for the 12-month period ended December 31, 2005 (the “Earnout Report”). If an Earnout Dispute Notice is not delivered pursuant to Section 2.4(c)(iii) below, then in no event later than 105 days following December 31, 2005, Parent shall pay or cause to be paid the Earnout Payment Amount in accordance with the terms of this Agreement, subject to the right of offset provisions of Sections 2.4(a), (b) and (d).

(ii) Parent shall keep full, clear and accurate books and records with respect to the Business. The books and records shall be maintained in such a manner that Net Revenue shall be readily verifiable. All books and records with respect to the Business shall be available for inspection by the Stockholders’ Agent or any attorney or accountant engaged by the Stockholders’ Agent to act on behalf of the Holders, in all cases upon reasonable prior notice and during normal business hours. The information contained in the books and records of Parent with respect to the Business shall remain confidential. Notwithstanding the foregoing, upon written request of the Stockholders’ Agent, Parent shall provide the Stockholders’ Agent with a report reflecting the estimate of the Net Revenue to date (which estimate is subject to change in the preparation of the Earnout Report) as promptly as practicable thereafter; provided that the Stockholders’ Agent may only make such a request once every six months commencing on July 1, 2005. If the Stockholders’ Agent does not deliver to Parent an Earnout Dispute Notice (as defined below) as set forth in Section 2.4(c)(iii) below, then the Earnout Report for the Earnout Period shall be deemed final and binding and neither the Stockholders’ Agent nor the Holders shall have any further right to contest the report, the computation of Net Revenue or payment of the Earnout Payment Amount.

(iii) In the event that the Stockholders’ Agent shall dispute the information set forth by Parent in the Earnout Report or, if based on the Stockholders’ Agent’s review of the books and records of the Business in accordance with subsection (c)(ii) above, omitted from the Earnout Report, as the case may be, then, within 60 calendar days following the date of the delivery by Parent of such report, the Stockholders’ Agent shall provide written notice to Parent (the “Earnout Dispute Notice”) specifying the amount disputed and the basis for the dispute, together with supporting documentation reflecting the analysis of and justification for any recomputation made. Parent and the Stockholders’ Agent shall make good faith efforts to resolve the dispute through negotiations for a period of 30 calendar days following the receipt of the written notice defining and describing the nature of the dispute. In the event that the parties are unable to finally resolve the dispute within such 30 calendar-day period, the parties to the dispute may elect by mutual agreement to extend the period of negotiation and may elect by mutual agreement to engage a mediator to assist in such negotiation. To the extent that any matter remains unresolved following negotiations (as determined by notice by any party to the other parties), the Stockholders’ Agent and Parent shall jointly select an independent accountant of recognized national standing to resolve any remaining disagreements, which independent accountant shall not have provided services to the Stockholders’ Agent, the Company or Parent or its affiliates during the five-year period preceding the date of its selection (the “Independent Accountant”). The Stockholders’ Agent and Parent shall use their respective commercially reasonable efforts to cause such Independent Accountant to make its determination within 60 calendar days of accepting its selection. Within 10 business days after the date of determination of such Independent Accountant, Parent shall pay or cause to be paid to the Holders the Earnout Payment Amount, if any, in the manner set forth herein, subject to the right of offset provisions of Sections 2.4(a), (b) and (d). The decision of the Independent Accountant shall be a final, binding, and conclusive resolution of the parties’ dispute, shall be non-appealable, and shall not be subject to further review. Irrespective of the Independent Accountant’s decision, the costs and expenses of the Independent Accountant shall be split equally between the parties. In the event that the Stockholders’ Agent does not pay the full amount of one-half of the Independent Accountant’s costs and expenses, Parent shall be entitled to deduct the difference between one-half of the costs and expenses of the Independent Accountant and the amount actually paid by the Stockholders’ Agent to the Independent Accountant from the Earnout Payment Amount. Notwithstanding the foregoing, in any case, the parties shall be responsible for the payment of their respective costs and expenses, including any attorneys’ and accountants’ fees (other than any accountants’ fees payable to the Independent Accountant, which shall be split equally between the parties) incurred in connection with the dispute. Notwithstanding the foregoing, in any case, the parties shall be responsible for the payment of their respective costs and expenses, including any attorneys’ and accountants’ fees (other than any accountants’ fees payable to the Independent Accountant, which shall be split equally between the parties) incurred in connection with the dispute.

(iv) The Holders will be deemed to, as part of their approval and adoption of the Merger Agreement and the transactions contemplated therein and herein, and the Stockholders’ Agent hereby, generally, irrevocably, unconditionally and completely agree that (1) the Company and Parent (as the controlling stockholder of the Company as of the Effective Time of the Merger) and each of their respective Affiliates shall be entitled to operate the Business after the Effective Time as they determine in their sole and absolute discretion, and shall have no obligation to operate the Business in any manner that would maximize, maintain or protect the value of the Common Stock CVRs and the Preferred Stock CVRs, and as a result of such operation of the Business, there may be a diminution in or elimination of the value of the CVRs, (2) the Common Stock CVRs and the Preferred Stock CVRs represent contractual obligations of Parent, and none of Parent, the Company or any of their respective Affiliates owes any fiduciary duty of any type (including, without limitation, any duty of loyalty or care) to any Holder of Common Stock CVRs and/or Preferred Stock CVRs, and (3) each of the Holders and the Stockholders’ Agent shall be prohibited from asserting any dispute, right, claim, action, cause of action, controversy or remedy of any kind and nature against any of the Company, Parent or any of their Affiliates resulting from the operation of the Business after the Effective Time or resulting from

any allegation of breach of fiduciary duty of any nature, other than claims for fraud or intentional misconduct (and other than the right of the Stockholders’ Agent to dispute the Closing Balance Sheet Payment under Section 2.4(b)(iii) and/or the Earnout Report under Section 2.4(c)(iii) above). Upon either (A) the occurrence of an allegation by the Stockholders’ Agent of any claim which may arise for fraud or intentional misconduct under this subsection (iv) or (B) the receipt by the Stockholders’ Agent of written notice made in accordance with Section 1.3 by any Holder to the Stockholders’ Agent of the occurrence of any claim which such Holder has a good faith belief has arisen for fraud or intentional misconduct under this subsection (iv) (in each case, a “Claim”), the Stockholders’ Agent shall provide notice of such Claim to Parent, stating, to the best of his or her understanding, the circumstances giving rise to the Claim, specifying the amount of the Claim and making a request for any payment then believed due (the “Notice”). Upon receipt of any such Notice by Parent, within the next 45 days thereafter, the parties shall use their reasonable best efforts to cooperate and arrive at a mutually acceptable resolution of such dispute. If a mutually acceptable resolution cannot be reached between the parties within such 45-day period, the Stockholders’ Agent may submit the dispute for resolution by a panel of three arbitrators selected from the panels of arbitrators of the American Arbitration Association in Santa Clara County, California; provided, however, that (i) one arbitrator shall be selected by the Stockholders’ Agent, the second arbitrator shall be selected by Parent and the third arbitrator shall be selected by the two previously selected arbitrators and (ii) in all respects, such panel shall be governed by the American Arbitration Association’s then existing Commercial Arbitration Rules. If it is finally determined that all or a portion of such Claim amount is owed to the Holders, Parent shall, within 10 days of such determination, pay the Holders such amount owed, together with interest from the date that the Stockholders’ Agent initially requested such payment until the date of actual payment, at an annual rate equal to the prime interest rate then generally in effect on the date of payment as set forth in The Wall Street Journal. The arbitration panel’s decision shall be final and binding upon the parties, and may be entered and enforced in any court of competent jurisdiction by any party. The parties shall be responsible for their respective fees and costs (including any attorneys’ or accountants’ fees) incurred in connection with the arbitration.

EACH HOLDER AND THE STOCKHOLDERS’ AGENT ACKNOWLEDGES AND AGREES THAT ANY CONTROVERSY WHICH MAY ARISE FOR FRAUD OR INTENTIONAL MISCONDUCT UNDER THE PRECEDING SENTENCE IS LIKELY TO INVOLVE COMPLICATED AND DIFFICULT ISSUES, AND THEREFORE IT HEREBY IRREVOCABLY AND UNCONDITIONALLY WAIVES ANY RIGHT IT MAY HAVE TO A TRIAL BY JURY IN RESPECT OF ANY LITIGATION DIRECTLY OR INDIRECTLY ARISING OUT OF OR RELATING TO FRAUD OR INTENTIONAL MISCONDUCT UNDER THE PRECEDING SENTENCE. EACH HOLDER AND THE STOCKHOLDERS’ AGENT CERTIFIES AND ACKNOWLEDGES THAT (A) NO REPRESENTATIVE, AGENT OR ATTORNEY OF ANY OTHER PARTY HAS REPRESENTED, EXPRESSLY OR OTHERWISE, THAT SUCH OTHER PARTY WOULD NOT, IN THE EVENT OF LITIGATION, SEEK TO ENFORCE SUCH WAIVER, (B) IT UNDERSTANDS AND HAS CONSIDERED THE IMPLICATIONS OF SUCH WAIVER, AND (C) IT MAKES SUCH WAIVER VOLUNTARILY.

(v) Notwithstanding anything to the contrary set forth in this Section 2.4(c), in the event of a Change of Control (as defined below) of Parent before December 31, 2005, the Aggregate Earnout Payment Amount payable pursuant to this Section 2.4(c) shall be at least $14,000,000 regardless of the actual Net Revenue recognized during the Earnout Period, subject, however, to the offset provisions of Section 2.4(a), (b) and (d). In event of a Change of Control of Parent as set forth herein, Parent shall make proper provisions so that the continuing or surviving corporation or entity shall assume the obligation to pay the Aggregate Earnout Payment Amount as set forth herein. For purposes of this Section 2.4(c)(v), a “Change of Control” shall mean (1) the consummation of any transaction, including without limitation, any merger or consolidation, pursuant to which any of the voting stock of Parent is converted into or exchanged for cash, securities or other property, other than any transaction where the voting stock of Parent outstanding immediately prior to such transaction is converted into or

exchanged for voting stock of the surviving or transferee entity constituting more than 50% of such voting stock of such surviving or transferee entity (immediately after giving effect to such issuance) and other than an acquisition of Parent in which the management of Parent participates in ten percent or more of the fully-diluted equity of the acquiror; or (2) a sale of all or substantially all of Parent’s assets.

(d) Offset Against Earnout Payment.

(i) Each statement contained in any Schedule or certificate delivered by or on behalf of the Company pursuant to this Agreement or the Merger Agreement shall be deemed to be a representation and warranty by the Company contained in this Agreement and the Merger Agreement. The representations and warranties of the Company contained in Article 3 of the Merger Agreement shall survive the Effective Time until March 30, 2006; provided, however, in the case of actual fraud, intentional misrepresentation or criminal activity, the representations and warranties of the Company shall survive until the expiration of the applicable statute of limitations. Any claims under this Agreement or the Merger Agreement with respect to a breach of a representation or warranty must be asserted by written notice within the applicable survival period contemplated by this Section 2.4(d)(i), and if such a notice is given, the survival period for such representation and warranty shall continue, solely with respect to such claim, until the claim is fully resolved. The right to recovery or other remedy based on the representations, warranties, covenants and agreements herein will not be affected by any investigation conducted with respect to, or any knowledge acquired by Parent or Merger Sub (or capable of being acquired) at any time, whether before or after the execution and delivery of this Agreement, the Merger Agreement or the Closing, with respect to the accuracy or inaccuracy of or compliance with any such representation, warranty, covenant or agreement. All representations and warranties of the Company set forth in this Agreement and the Merger Agreement shall be deemed to have been made again by the Company at and as of the Closing Date. The waiver of any condition based on the accuracy of any representation or warranty, or on the performance of or compliance with any covenant or agreement, will not affect the right to recovery or other remedy based on such representations, warranties, covenants and agreements, unless such right is also expressly waived.

(ii) Subsequent to the Closing, Parent shall be entitled to offset against the Earnout Payment Amount an amount in cash equal to the amount of any damage, claim, loss, cost, tax liability or expense, including, without limitation, interest, penalties, reasonable attorneys’ fees and expenses of investigation, response action, removal action or remedial action (including any consequential or punitive damages) (collectively “Damages”) incurred by Parent and its respective Affiliates (including, after the Closing, the Company), and each of its respective officers, directors, employees, stockholders, partners and agents (the “Covered Parties”) that arise out of or relate to, whether directly or indirectly: (i) any misrepresentation or breach of any warranty on the part of the Company contained in this Agreement, the Merger Agreement or in any Schedule or certificate delivered by or on behalf of the Company pursuant to this Agreement or the Merger Agreement, or (ii) any breach or non-performance by the Company of any of their respective covenants or agreements contained in this Agreement, the Merger Agreement or in any Schedule or certificate delivered by or on behalf of the Company pursuant to this Agreement or the Merger Agreement.

(iii) The term “Damages” as used in this Section 2.4(d) is not limited to matters asserted by third parties against the Covered Parties, but includes Damages incurred or sustained by such persons in the absence of third-party claims, and payments by a Covered Party shall not be a condition precedent to recovery.

(iv) In the event that Parent seeks recovery under Section 2.4(d) hereunder, it shall, within the relevant limitation period provided for in Section 2.4(d)(i) above, give to the Stockholders’ Agent a notice (a “Claim Notice”) describing in reasonable detail the facts giving rise to any claims for offset under Section 2.4(d) hereunder, to the best of its understanding, and shall include in such Claim Notice (if then known) the amount or the method of computation of the amount of such claim, and a reference to the provision of this Agreement or any agreement, certificate or instrument executed pursuant hereto

or in connection herewith upon which such claim is based; provided, however, that a Claim Notice in respect of any action at law or suit in equity by or against a third Person as to which recovery will be sought shall be given promptly after the action or suit is commenced; and provided further, that failure to give such notice shall not prejudice the rights of Parent hereunder except to the extent that the Holders shall have been materially prejudiced by such failure. In the event that any Claim Notice is delivered and thereafter any Earnout Payment Amount is required to be paid hereunder, payment shall not be required of that portion of the Earnout Payment Amount equal to the amount of outstanding claims (as determined by Parent in good faith, in its sole discretion) until such time as Parent’s right of offset under this Section 2.4(d) has been finally resolved.

(v) The Stockholders’ Agent shall have sixty (60) days after receipt of any Claim Notice pursuant hereto to (i) agree to the amount or method of determination set forth in the Claim Notice and agree that the amount set forth in the Claim Notice shall be offset by Parent against the Earnout Payment Amount in accordance with Section 2.4(d)(ii) hereof or (ii) to provide Parent with notice that it disagrees with the amount or method of determination set forth in the Claim Notice (the “Offset Dispute Notice”). Within fifteen (15) days after the giving of any Dispute Notice, the Stockholders’ Agent and Parent shall negotiate in a bona fide attempt to resolve the matter. If no Dispute Notice is given, then the claim in the amount alleged by the Covered Party in the Claim Notice shall be deemed to be valid and may be offset against the Earnout Payment Amount pursuant to Section 2.4(d)(ii) hereof. No claim shall be offset against the Earnout Payment Amount if such claim is timely disputed as set forth above, unless and until its validity is finally resolved.

(vi) If a claim by a third Person is made against a Covered Party, and if Parent intends to seek a right of offset with respect thereto under this Section 2.4(d), Parent shall promptly notify the Stockholders’ Agent in writing of such claims, setting forth such claims in reasonable detail. Failure to give such notice shall not prejudice the rights of Parent hereunder except to the extent that the Holders shall have been materially prejudiced by such failure. Parent shall have the right to undertake, at the Holders’ cost, risk and expense (which amounts Parent shall be entitled to offset against the Earnout Payment Amount), the defense, compromise or settlement of the claim but shall not thereby waive any right of offset therefor pursuant to this Agreement.

(e) California Holdback Payment. As promptly as practicable after the expiration of all applicable statutes of limitations (and any extensions thereof) relating to the Company’s 2002 California tax return referred to in Section 5.14 of the Merger Agreement, Parent shall pay or cause to be paid the California Holdback Payment Amount.

Section 2.5 Payments on CVRs.

(a) If any CVR Payment Amount is determined to be payable in accordance with Section 2.4, Parent shall establish a CVR Payment Date with respect to such CVR Payment Amount that is within 15 days following the date on which it is determined that a CVR Payment Amount is payable. On such CVR Payment Date, Parent shall then deposit with the Rights Agent the CVR Payment Amount, and the Right Agent shall cause such amount to be delivered to each of the Holders entitled thereto by check mailed to the address of each Holder as reflected in the CVR Register as of the close of business on the last Business Day prior to such CVR Payment Date.

(b) The determination by Parent of any CVR Payment Amount pursuant to the procedures set forth in Section 2.4, absent a mathematical error, shall be final and binding on Parent and each Holder; provided that in the event that the Stockholders’ Agent disputes the information set forth by Parent in the Balance Sheet Report or the Earnout Report, as the case may be, in accordance with Section 2.4, the CVR Payment Amount determined by agreement of the parties, by the Balance Sheet Independent Accountant or by the Independent Accountant, as the case may be, shall be final and binding on Parent and each Holder.

(c) Except in the specific cases specified in this Agreement, no interest shall accrue on any amounts payable on the CVRs to any Holder.

(d) Parent and the Rights Agent shall be entitled to deduct and withhold, or cause to be deducted or withheld, from the CVR Payment Amount otherwise payable pursuant to this Agreement such amounts as 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. To the extent that amounts are so withheld or paid over to or deposited with the relevant governmental entity, such withheld amounts shall be treated for all purposes of this Agreement as having been paid to the Holder in respect of which such deduction and withholding was made.

For purposes of this Section 7.1, “convey, transfer or lease its properties and assets substantially as an entirety” shall mean properties and assets contributing in the aggregate at least 80% of Parent’s or the Company’s total consolidated revenues as reported in Parent’s or the Company’s last available periodic financial report (quarterly or annual, as the case may be).

Any amounts remaining unclaimed by Holders seven years after the applicable CVR Payment Date (or such earlier date immediately before that time when the amounts would otherwise escheat to or become property of any governmental authority) shall become, to the extent permitted by applicable law, the property of Parent free and clear of any claims or interest of any person previously (or subsequently claiming to be) entitled thereto.

The parties acknowledge that Parent shall have no liability for either the holding or disbursement of any funds under this arrangement. In the event that the Stockholders’ Agent’s fees and expenses (including any third party fees and expenses payable by the Stockholders’ Agent hereunder) exceed $300,000, then Parent shall pay and deduct from the Earnout Payment Amount, if any, an amount equal to the lesser of (1) the Aggregate Earnout Payment Amount (excluding any deduction set forth in subsection (F) of the definition of “Aggregate Earnout Payment Amount”) and (2) any fees and expenses of the Stockholders’ Agent (including any third party fees and expenses payable by the Stockholders’ Agent hereunder) in excess of $300,000.

A decision, act, consent or instruction of the Stockholders’ Agent shall constitute a decision of all Holders and shall be final, binding and conclusive upon each such Holder, and Parent may rely upon any decision, act, consent or instruction of the Stockholders’ Agent as being the decision, act, consent or instruction of each and every such Holder. Parent is hereby relieved from any liability to any person for any acts done by it in accordance with such decision, act, consent or instruction of the Stockholders’ Agent.
