Promptly, but not later than ten (10) days after its acceptance of its appointment, the Arbiter will determine (based solely on written presentations by and a review of the working papers of Seller, Buyer and their respective independent accountants and not by independent review) only those matters in dispute and will render a written report as to the disputed matters and the resulting balance sheet of Company as of the Closing Date (in either case, whether determined by the parties without involvement of the Arbiter as required by this subsection (b) or whether determined by such Arbiter in accordance with this subsection (b), the “Closing Date Balance Sheet”), which report will be conclusive and

               (d) The Purchase Price shall also be reduced dollar-for-dollar by the balance, if any, of the Intercompany Note Payable plus any other liabilities shown on the Closing Date Balance Sheet which are not taken into account in connection with the calculation of Working Capital; provided, however, that the Purchase Price shall not be reduced by the balance, if any, of any of the long term liabilities described on Schedule 3.15 hereof that are shown on the Closing Date Balance Sheet. Seller shall pay to Buyer the amount of such reduction in cash within five (5) days after final determination of such amount in accordance with this Section 2, by wire transfer of immediately available funds to an account designated by Buyer.

               (e) For purposes of complying with the terms set forth herein, each party will cooperate with and make available to the other party and its independent accountants and representatives all information, records, data and independent accountants’ working papers, and will permit access to its facilities and personnel, as may be reasonably required in connection with the preparation and analysis of the Closing Date Balance Sheet (and each of the components thereof, including without limitation, Working Capital) and the resolution of any disputes thereunder.

          2.5 Section 338(h)(10) Election. Seller and Buyer hereby covenant and agree to validly elect under Section 338(h)(10) of the Code, and under any analogous provision of state or local Law (each such election, a “Section 338 Election”) to treat the purchase of the Stock as a purchase of assets solely for income tax purposes as provided under the Code. Within ninety (90) days after Closing, Company and Seller shall deliver to Buyer an IRS Form 8023 executed by Seller (“Form 8023”) and Seller shall cooperate with Buyer to take all actions necessary and appropriate (including filing such additional forms, returns, elections schedules and other documents as may be required) to effect and preserve a timely election, in accordance with the provisions of Treasury Regulation Section 1.338(h)(10)(1).

          2.6 Payments. Seller shall pay all fees, commissions and charges of any broker, finder or investment banker in connection with the transactions contemplated by this Agreement based upon arrangements made by or on behalf of Company or Seller. Seller shall pay, on or before the Closing Date, all amounts payable for legal, accounting and other fees and expenses related to the transactions contemplated by this Agreement due by or on behalf of Company, except to the extent included as a liability or reserve on the Closing Date Balance Sheet (and thus taken into account in connection with the calculation of Working Capital), in which case, Company shall retain such liabilities and pay such amounts.

48

extent that Seller becomes obligated to indemnify the Buyer Parties pursuant to this subsection (c), Buyer shall take all actions reasonably requested by Seller to assign to Seller, upon Seller’s satisfaction of such indemnification obligations, all of Buyer’s (or any of its Affiliates’) rights under such sublease to receive such corresponding payment(s) from Washington Mutual Bank, FA, such that Seller will thereafter be entitled to pursue any and all contribution, collection or other actions or remedies against Washington Mutual Bank, FA in connection with such corresponding payment(s), (d) the failure of Company to terminate the Terminated Employees in accordance with Section 12.4 below, or (e) the successful enforcement by the Buyer Parties’ of their indemnification rights provided for hereunder.

Except as otherwise expressly provided herein, the covenants and agreements contained in this Agreement shall survive for two (2) years following the execution and delivery hereof and the consummation of the transactions contemplated hereby, and then only to the extent that the party asserting a claim

49

shall given notice of such claim to the other party on or prior to the end of such applicable survival period. Notwithstanding the fact that any Person may have the right to assert claims for indemnification or reimbursement under or in respect of more than one provision of this Agreement (including without limitation Section 2.4 hereof) or any other agreement entered into in connection with this Agreement in respect of any fact, event, condition or circumstance, no Person shall be entitled to recover the amount of any adverse consequences suffered by such Person more than once under all such agreements in respect of such fact, event, condition or circumstance.

          11.4 Certain Limitations on Indemnification Obligations. Notwithstanding anything else in this Agreement to the contrary:

               (a) Neither the Buyer Parties nor the Seller Parties, as applicable, shall be entitled to receive any indemnification as set forth in Sections 11.1 and 11.2, until the aggregate amount of all Losses incurred by such party seeking indemnification exceeds One Hundred Twenty-Five Thousand Dollars ($125,000) (the “Deductible Amount”), after which, such party shall only be entitled to receive indemnification payments for the amount of such indemnifiable Losses in excess of the Deductible Amount.

               (b) The maximum aggregate amount of indemnification payments payable by each of the Buyer Parties or Seller Parties under Section 11 shall not exceed Two Million One Hundred Twenty-Five Thousand Dollars ($2,125,000) (the "Cap Amount”). In the event that the Buyer Parties or Seller Parties, as applicable, have incurred any indemnifiable Losses in excess of any applicable Deductible Amount, upon written notice thereof to the indemnifying party describing the amount of and basis for such Loss, the parties will attempt in good faith to reach an agreement as to any matters or amounts in dispute. If the authorized parties of each of Buyer and Seller, notwithstanding such good faith effort, fail to resolve all matters in dispute within thirty (30) days after an indemnified party notifies the indemnifying party of the Losses incurred thereby, then either party may be submit the disputed matters to an independent mediator selected by Buyer and Seller if the other party consents to such mediation, which mediator will, for a period of not more than sixty (60) days, attempt to assist the parties to resolve all disputes in connection with such matter. Notwithstanding anything to the contrary contained in this Section 11.4(b), at any time before, during or after the procedures described above, an indemnified party may bring a claim on account of a Loss with an appropriate Governmental Authority pursuant to the terms of this Agreement.

               (c) Notwithstanding the limitations set forth in Sections 11.3 and subsections (a) and (b) of this Section 11.4, in the case of Losses resulting from (i) any fraudulent misrepresentation contained herein or in any other Transaction Documents, the time periods for indemnification shall commence running upon the discovery of such fraudulent misrepresentation and each party’s indemnification obligation shall not be subject to the Deductible Amount or limited by the Cap Amount, (ii) the Washington Mutual Bank, FA indemnification described in Section 11.1(c), Seller’s indemnification shall not be subject to the Deductible Amount or limited by the Cap Amount, and the time periods for indemnification shall commence running upon the discovery of such failure to make adequate payment by Washington Mutual Bank, FA or (iii) breach by Seller of its representation in the last sentence of Section 3.19(g) hereof, Seller’s indemnification shall not be subject to the Deductible Amount or limited by the Cap Amount.

50

          11.5 Defense of Claims. In the case of any claim for indemnification under Section 11.1 or 11.2 arising from a claim of a third party (including the IRS or any Governmental Authority), promptly upon receipt of notice or any knowledge of such claims, and in no case later than ten (10) days thereafter, an indemnified party shall give written notice, to the indemnifying party of any claim, suit or demand of which such indemnified party has knowledge and as to which it may request indemnification hereunder. The failure to give such notice shall not relieve the indemnifying party of its indemnification obligations hereunder, except to the extent that the indemnifying party is actually harmed thereby. The indemnifying party shall have the right upon written notice to the indemnified party within thirty (30) days, after receipt of a request for indemnification from such party to defend and to direct the defense against any such claim, suit or demand, in its name and at its expense, and with counsel selected by the indemnifying party unless such claim, suit or demand seeks an injunction or other equitable relief against the indemnified party. If the indemnifying party elects to compromise or defend such claim, the indemnified party shall, at the request and expense of the indemnifying party, cooperate in the defense of such claim, suit or demand. If the indemnifying party elects not to pay, compromise or defend such claim or fails to notify or inform the indemnified party of its election as herein provided following a request therefrom, the indemnified party may pay, compromise or defend such claim. Except as set forth in the immediately preceding sentence, the indemnifying party shall have no indemnification obligations with respect to any such claim, suit or demand that is settled by the indemnified party without the prior written consent of the indemnifying party (which consent shall not be unreasonably withheld or delayed); provided, however, that notwithstanding the foregoing, the indemnified party shall not be required to refrain from paying any claim which has matured by a court judgment or decree, unless an appeal is duly taken therefrom and exercise thereof has been stayed, nor shall it be required to refrain from paying any claim where the delay in paying such claim would result in the foreclosure of a Lien upon any of the property or assets then held by the indemnified party or where any delay in payment would have a Material Adverse Effect on the indemnified party. The indemnifying party’s right to direct the defense shall include the right to compromise or enter into an agreement settling any claim by a third party; provided that no such compromise or settlement shall obligate the indemnified party to agree to any settlement which requires the taking of any action by the indemnified party other than the delivery of a release, except with the consent of the indemnified party (such consent not to be unreasonably withheld or delayed). Except as expressly provided herein to the contrary, the indemnified party shall have the right to participate at its sole cost and expense in the defense of any claim, suit or demand with counsel selected by it subject to the indemnifying party’s right to direct the defense. The fees and disbursements of such counsel shall be at the expense of the indemnified party.

          11.6 Non-Third Party Claims. Any claim which does not arise out of or result in a third party claim shall be asserted by written notice to the other party or parties pursuant to Section 16 of this Agreement within thirty (30) days after an indemnified party has any knowledge of a Loss. The recipient of such notice shall have a period of sixty (60) days after receipt of such notice within which to respond thereto. If the recipient does not respond within such sixty (60) day period, the recipient shall be deemed to have accepted responsibility for the Losses set forth in such notice and shall have no further right to contest such Losses. If the recipient responds within such sixty (60) days after the receipt of the notice and rejects such claim in whole or in part, the party delivering such notice shall be free to pursue such remedies as may be available to it under Section 11 of this Agreement.

51

          11.7 Tax Treatment. Unless otherwise required by applicable Law, all indemnification payments shall constitute adjustments to the Purchase Price for all Tax purposes, and no party shall take any position inconsistent with such characterization.

          11.8 No Right of Contribution. Seller shall have no right to seek contribution from Company or Buyer with respect to all or any part of any of Seller’s indemnification obligations under Section 11.

          11.9 Mitigation. Each indemnified party shall have an obligation to mitigate Losses under this Agreement, and to that end each party shall use its reasonable best efforts and shall consult and cooperate with the other with a view towards mitigating Losses that may give rise to claims for indemnification under Section 11.

          11.10 Reduction of Liability. With respect to any Losses required to be indemnified pursuant to this Agreement, so long as the indemnifying party has complied with its indemnification obligations with respect thereto (a) to the extent available, the indemnified party shall assign to the indemnifying party any applicable proceeds under any warranty, insurance policy, litigation or settlement which covers the matter which is the subject of the indemnification (but only to the extent of indemnification actually paid by the indemnifying party) and shall take reasonable steps to ensure that the indemnifying party obtains the benefits of such warranty, policy, litigation or settlement, including providing any notices as required under such warranty, policy, litigation or settlement and (b) if the indemnified party receives proceeds on account of such warranty, insurance policy, litigation or settlement with respect to any Losses paid by the indemnifying party, then the indemnified party shall reimburse the indemnifying party in an amount equivalent to such proceeds up to the amount actually paid by the indemnifying party.

     12. POST CLOSING MATTERS. The parties agree as follows with respect to the period following the Closing Date:

          12.1 Cooperation. In case at any time after the Closing any further action is necessary to carry out the purposes of this Agreement, each of the parties will take such further action (including the execution and delivery of such further instruments and documents) as any other party reasonably may request, all at the sole cost and expense of the requesting party (unless the requesting party is entitled to indemnification therefor under Section 11 hereof). Seller acknowledges and agrees that from and after the Closing Buyer will be entitled to possession of and Seller will provide to Buyer all documents, books, records (including Tax records), agreements, corporate minute books and financial data of any sort relating to Company.

          12.2 Litigation Support. In the event and for so long as any party is actively contesting or defending against any action, suit, proceeding, hearing, investigation, charge, complaint, claim, or demand in connection with (i) any transaction contemplated under this Agreement other than a dispute among the parties to this Agreement or (ii) any fact, situation, circumstance, status, condition, activity, practice, plan, occurrence, event, incident, action, failure to act, or transaction that existed on or prior to the Closing Date involving Company, each of the other parties will cooperate with such party and such party’s counsel in the contest or defense, make available their personnel, and provide such testimony and access to their books and records as shall be reasonably necessary in connection with the contest or defense, all at the sole cost and expense of the contesting or defending party (unless the contesting or defending party is entitled to indemnification therefor under Section 11 hereof).

          12.3 Transition. Seller will not take any action that is designed or intended to have the effect of discouraging any lessor, licensor, customer, supplier, or other business associate of Company from maintaining the same business relationships with Company after the Closing as it maintained with Company prior to the Closing. Seller will refer all customer inquiries relating to the business of Company to Company and/or Buyer from and after the Closing.

          12.4 Termination of Certain Employees.

          12.5 Books and Records. Each party agrees that it will reasonably cooperate with and make available (or cause to be made available) to the other party, during normal business hours, all books and records, information and employees (without substantial disruption of employment) retained, remaining in existence or continuing to be employed after the Closing Date which are necessary or useful in connection with any Tax inquiry, audit, or dispute, any litigation or investigation or any other matter requiring any such books and records, information or employees for any reasonable business purpose (a “Permitted Use”). The party requesting any such books and records, information or employees shall bear all of the out-of-pocket costs and expenses reasonably incurred in connection with providing such books and records, information or employees. All information received pursuant to this Section 12.5 shall be kept confidential by the party receiving it, except to the extent that disclosure is required by Law or is otherwise reasonably necessary in connection with any Permitted Use.

Such cooperation shall include the return and (upon the other party’s request) the provision of records and information which are reasonably relevant to any such audit, litigation or other proceeding and making employees available on a mutually convenient basis to provide additional information and explanation of any material provided hereunder. Company and Seller agree (A) to retain all books and records with respect to Tax matters pertinent to Company relating to any taxable period ending on or before the Closing Date until the expiration of the statute of limitations (and, to the extent notified by Buyer or Seller, any extensions thereof) of the respective taxable periods, and to abide by all record retention agreements entered into with any taxing authority, and (B) to give the other party reasonable written notice prior to transferring, destroying or discarding any such books and records and, if the other party so requests, Company or Seller, as the case may be, shall allow the other party to take possession of such books and records.

Seller shall bear its own legal and other fees and expenses incurred in connection with this Agreement after the Closing, including, without limitation, any related broker’s or finder’s fees, subject to the provisions of this Agreement.
