          (e) Buyer shall pay the Sellers the Fourth Cash Payment by wire transfer of immediately available funds to the Payment Account no later than 10 days after the following is satisfied:

     (i) No later than February 15, 2006, (y) the 612 ONT SFH shall be released for production and (z) the Company achieves a ▇▇▇▇ of materials with respect to the 612 ONT SFH having BOM Expenses of $210 (assuming production of 500,000 units) and Buyer is able to independently verify such BOM Expenses through its own supply chain.

6

“Verizon Delay”), then any and all subsequent dates provided for above in items (A), (B) or (C) of clause (d)(i) above shall be extended by a period equal to the period of the Verizon Delay.

If any of the foregoing conditions for making a Subsequent Cash Payment is not satisfied by the date specified herein for such condition to be satisfied, as such date maybe extended in accordance with such foregoing conditions, the Sellers will cease to be entitled to such Subsequent Cash Payment and the Purchase Price will be reduced by such amount.

          (a) Buyer has the corporate power and authority to execute and deliver this Agreement and all of the other agreements and instruments to be executed and delivered by Buyer pursuant hereto (the “Buyer Ancillary Agreements”), to consummate the transactions contemplated hereby and thereby and to comply with the terms, conditions and provisions hereof and thereof.

          (b) The execution, delivery and performance of this Agreement and the Buyer Ancillary Agreements by Buyer have been duly authorized and approved by all necessary corporate action on behalf of Buyer’s Board of Directors and do not require any further authorization or consent of Buyer. This Agreement constitutes and each Buyer Ancillary Agreement, when executed and delivered by Buyer and the other parties thereto, will constitute the legal, valid and binding agreement of Buyer enforceable in accordance with its respective terms.

          (c) Assuming the accuracy of the Sellers representations contained in Section 2.31, neither the execution and delivery of this Agreement or any Buyer Ancillary Agreement by Buyer or the consummation by Buyer of any of the transactions contemplated hereby or thereby nor compliance by Buyer with or fulfillment by Buyer of the terms, conditions and provisions hereof or thereof will:

     (i) conflict with, result in a breach of the terms, conditions or provisions of, or constitute a default, an event of default or an event creating rights of acceleration, termination or cancellation or a loss of rights under, the Certificate of Incorporation or By-laws of Buyer or any material agreement or any judgment, order, award or decree to which Buyer is a party or any of its properties is subject or by which Buyer is bound; or

     (ii) require the approval, consent, authorization or act of, or the making by Buyer of any declaration, filing or registration with, any third party or any foreign, federal, state or local court, governmental or regulatory body.

          Section 3.3 Capital Structure. As of the date hereof, the authorized capital stock of Buyer consists of 1,000,000,000 shares of Buyer Common Stock and 5,000,000 shares of preferred stock, $0.01 par value (the “Buyer Preferred Stock”). At the close of business on December 20, 2004, (i) 462,202,989 shares of Buyer Common Stock were issued and outstanding, (ii) no shares of Buyer Common Stock were held in the treasury of Buyer or by Subsidiaries of Buyer, (iii) no shares of Buyer Preferred Stock were issued or outstanding, (iv) 66,947,568 shares of Buyer Common Stock were reserved for issuance pursuant to outstanding options, warrants or other rights to purchase or otherwise acquire shares of Buyer Common Stock under Buyer’s plans or other arrangements or pursuant to any plans or arrangements

34

assumed by Buyer in connection with any acquisition, business combination or similar transaction (collectively, the “Buyer Stock Plans”), and (v) 153,483 stock appreciation rights granted pursuant to the Buyer Stock Plans were outstanding. As of the date of this Agreement, except as set forth above and, except for the issuance of shares of Buyer Common Stock pursuant to the Buyer Stock Plans, no shares of capital stock or other voting securities of Buyer were issued, reserved for issuance or outstanding.

          Section 3.4 SEC Documents and Other Reports. Buyer has filed all required documents with the Securities and Exchange Commission (the “SEC”) between January 1, 2004 and the date hereof (the “Buyer SEC Documents”). As of their respective dates or, if amended, as of the date of the last amendment, the Buyer SEC Documents complied in all material respects with the requirements of the Securities Act or the Exchange Act, as the case may be, and, at the respective times they were filed, none of the Buyer SEC Documents contained any untrue statement of a material fact or omitted to state a material fact required to be stated therein or necessary to make the statements therein, in light of the circumstances under which they were made, not misleading. The consolidated financial statements (including, in each case, any notes thereto) of Buyer included in the Buyer SEC Documents complied as to form in all material respects with applicable accounting requirements and the published rules and regulations of the SEC with respect thereto, were prepared in accordance with generally accepted accounting principles (“GAAP”) (except, in the case of the unaudited statements, as permitted by Form 10-Q of the SEC) applied on a consistent basis during the periods involved (except as may be indicated therein or in the notes thereto) and fairly presented in all material respects the consolidated financial position of Buyer and its consolidated Subsidiaries as at the respective dates thereof and the consolidated results of their operations and their consolidated cash flows for the periods then ended (subject, in the case of unaudited statements, to normal year-end audit adjustments and to any other adjustments described therein).

          Section 3.7 No Other Representations.

ARTICLE IV
ADDITIONAL AGREEMENTS

          Section 4.1 Covenant Not to Compete or Solicit Business. In furtherance of the sale of the Shares and the Company to Buyer and the cancellation of the Options hereunder by virtue of the transactions contemplated hereby and more effectively to protect the value and goodwill of the Company and the Business, each of the persons on Schedule 4.1 (collectively the “Restricted Persons”) covenants and agrees that, for a period ending on the third anniversary of the Closing Date, neither such Restricted Person nor any of its Affiliates will:

     (i) directly or indirectly (whether as principal, agent, independent contractor, partner or otherwise) own, manage, operate, control, participate in, perform services for, or otherwise carry on, a business similar to or competitive with the Business anywhere in the world (it being understood by the parties hereto that the Business is not limited to any particular region of the world and that such business may be engaged in effectively from any location in any country); or

     (ii) induce or attempt to persuade any employee, agent or customer of the Company to terminate such employment, agency or business;

provided, however, that nothing set forth in this Section 4.1 shall prohibit the Restricted Persons or their Affiliates from owning not in excess of 2% in the aggregate of any class of capital stock of any corporation if such stock is publicly traded and listed on any national or regional stock exchange or reported on the National Association of Securities Dealers Automated Quotations (Nasdaq) System. In addition, each of the Restricted Persons covenants and agrees that neither it nor any of its Affiliates will divulge or make use of any trade secrets or other confidential information of the Company other than to disclose such secrets and information to Buyer or its Affiliates.

          In the event any of the Restricted Persons or any Affiliate of Restricted Persons violates any of its obligations under this Section 4.1, Buyer may proceed against it in law or in equity for such damages or other relief as a court may deem appropriate. Restricted Persons acknowledge that a violation of this Section 4.1 may cause Buyer irreparable harm which may not be adequately compensated for by money damages. Restricted Persons therefore agree that in the event of any actual or threatened violation of this Section 4.1, Buyer shall be entitled, in addition to other remedies that it may have, to a temporary restraining order and to preliminary and final injunctive relief against Restricted Persons or such Affiliate of Restricted Persons to prevent any violations of this Section 4.1, without the necessity of posting a bond. The prevailing party in any action commenced under this Section 4.1 shall also be entitled to receive reasonable attorneys’ fees and court costs. It is the intent and understanding of each party hereto that if, in any action before any court or agency legally empowered to enforce this Section 4.1, any term, restriction, covenant or promise in this Section 4.1 is found to be unreasonable and for that reason unenforceable, then such term, restriction, covenant or promise shall be deemed modified to the extent necessary to make it enforceable by such court or agency. Nothing contained in Section 5.4 shall be deemed in any way to limit or restrict Buyer’s rights under this paragraph.

36

          Section 4.2 Tax Matters.

          (a) (i) Each of the Sellers, jointly and severally, shall be liable for, and pursuant to Article V agrees to indemnify and hold harmless each Buyer Group Member from and against any and all Losses and Expenses incurred by such Buyer Group Member in connection with or arising from all Taxes imposed on the Company or for which the Company may otherwise be liable (A) as a result of having been a member of any Company Group (including, without limitation, Taxes for which the Company or any Subsidiary of the Company may be liable pursuant to Treasury Regulation § 1.1502-6 or similar provisions of state, local or foreign law as a result of having been a member of a Company Group or any obligations to contribute to the payment of a Tax determined on a combined, consolidated or unitary basis with respect to any Company Group and any Taxes resulting from the Company or any Subsidiary of the Company ceasing to be a member of any Company Group) or (B) for any taxable year or period that ends on or before the Closing Date and, with respect to any Straddle Period, the portion of such Straddle Period ending on and including the Closing Date; provided, however, that in the case of any taxable year or period that begins before the Closing Date and for which the Tax Return is required to be filed by Buyer pursuant to Section 4.2(b), no Seller shall have any liability under this Section 4.2(a) with respect thereto to the extent of the Taxes shown to be due on such Tax Return when initially filed (or, in the case of any Straddle Period, the portion of such Taxes so shown that are attributable under Section 4.2(a)(iii) to the period ending on and including the Closing Date), it being agreed that this proviso shall not apply to the extent such Taxes so shown are or were (1) income or franchise Taxes that individually or in the aggregate exceed $20,000, (2) not incurred in the ordinary course of the Company’s business, (3) computed by taking into account any deduction for compensation arising as a result of the transactions contemplated by this Agreement, (4) not properly withheld or remitted under applicable law or (5) attributable to the transactions contemplated by this Agreement (Taxes described in this proviso “Accrued Pre-Closing Taxes”). For the avoidance of doubt, the parties agree that for purposes of this Section 4.2(a)(i) Taxes of the Company shall be computed by taking into account the application of any net operating loss carryovers or net capital loss carryovers of the Company available as of the Closing Date (as adjusted from time to time as a result of any audit or other examination affecting the amount thereof), in all cases to the extent such application is permitted under applicable Tax law.

     (ii) Buyer shall be liable for, and pursuant to Article V agrees to indemnify and hold harmless each Seller Group Member from and against any and all Losses and Expenses incurred by such Seller Group Member in connection with or arising from (A) Taxes imposed on the Company for any taxable year or period that begins after the Closing Date and, with respect to any Straddle Period, the portion of such Straddle Period beginning after the Closing Date and (B) Accrued Pre-Closing Taxes; provided, however, that Buyer shall not be liable for or pay, and shall not indemnify the Sellers against, any Taxes for which the Sellers are liable under this Agreement (including, without limitation, Section 2.10 and Section 4.2(a)(i)).

     (iii) For purposes of paragraphs (a)(i) and (a)(ii) immediately above, whenever it is necessary to determine the liability for Taxes of the Company for a Straddle Period, the determination of the Taxes of the Company for the portion of the Straddle Period ending on and including, and the portion of the Straddle Period beginning after, the

37

Closing Date shall be determined by assuming that the Straddle Period consisted of two taxable years or periods, one which ended at the close of the Closing Date and the other which began at the beginning of the day following the Closing Date, and items of income, gain, deduction, loss or credit of the Company for the Straddle Period shall be allocated between such two taxable years or periods on a “closing of the books basis” by assuming that the books of the Company were closed at the close of the Closing Date, provided, however, that exemptions, allowances or deductions that are calculated on an annual basis, such as the deduction for depreciation, shall be apportioned between such two taxable years or periods on a daily basis.

     (iv) Each of the Sellers, jointly and severally, shall be liable for, and pursuant to Article V agrees to indemnify and hold harmless each Buyer Group Member from and against any and all Losses and Expenses incurred by such Buyer Group Member in connection with or arising from any real property transfer or gains Tax, sales Tax, use Tax, stamp Tax, stock transfer Tax, or other similar Tax imposed on the transactions contemplated by this Agreement.

     (v) If any Seller becomes entitled to a refund or credit of Taxes for which it is liable under paragraph (a) to indemnify a Buyer Group Member, and such refund or credit is attributable to the carryback of losses, credits or similar items from a taxable year or period that begins after the Closing Date and is attributable to the Company or any Subsidiary of the Company, the Sellers shall promptly pay to Buyer the amount of such refund or credit together with any interest thereon. In the event that any refund or credit of Taxes for which a payment has been made to Buyer is subsequently reduced or disallowed, Buyer shall indemnify and hold harmless the Sellers for any Tax assessed against the Sellers by reason of the reduction or disallowance.

     (vi) On the Closing Date, each Seller shall deliver to Buyer a complete and signed IRS Form W-8 or W-9, whichever is appropriate for such Seller.

          (b) The Sellers shall timely file or cause to be timely filed when due (taking into account all extensions properly obtained) all Tax Returns that are required to be filed by or with respect to the Company prior to the Closing Date and the Sellers shall remit (or cause to be remitted) any Taxes due in respect of such Tax Returns, and Buyer shall timely file or cause to be timely filed when due (taking into account all extensions properly obtained) all Tax Returns that are required to be filed by or with respect to the Company on or after the Closing Date and Buyer shall remit (or cause to be remitted) any Taxes due in respect of such Tax Returns. The Sellers or Buyer shall reimburse the other party the Taxes for which the Sellers or Buyer is liable pursuant to paragraph (a) of this Section 4.2 but which are payable with any Tax Return to be filed by the other party pursuant to the previous sentence upon the written request of the party entitled to reimbursement setting forth in detail the computation of the amount owed by the Sellers or Buyer, as the case may be, but in no event earlier than 10 days prior to the due date for filing such Tax Return. All Tax Returns which the Sellers are required to file or cause to be filed in accordance with this paragraph (b) shall be prepared and filed in a manner consistent with past practice and, on such Tax Returns, no position shall be taken, elections made or method adopted that is inconsistent with positions taken, elections made or methods used in preparing and filing similar Tax Returns in prior periods (including, but not limited to, positions which would have

38

the effect of deferring income to periods for which Buyer is liable or accelerating deductions to periods for which the Sellers are liable).

          (c) Buyer shall notify the Seller Representative upon receipt by Buyer, any of its Affiliates, or the Company of notice of any pending or threatened federal, state, local or foreign Tax audits or assessments which may materially affect the Tax liabilities of the Company for which the Sellers would be required to indemnify Buyer pursuant to paragraph (a) of this Section 4.2, provided that failure to comply with this provision shall not affect Buyer’s right to indemnification hereunder.

          The Company shall have the sole control in any Tax audit or administrative or court proceeding relating to taxable periods ending on or before the Closing Date; provided, however, that the Seller Representative shall be permitted, at his expense, to be present at, and participate in, any such audit or proceeding.

          (d) After the Closing Date, each of the Sellers and Buyer shall (and shall cause their respective Affiliates to):

     (i) timely sign and deliver such certificates or forms as may be necessary or appropriate to establish an exemption from (or otherwise reduce), or file Tax Returns or other reports with respect to, Taxes described in paragraph (a)(iv) of this Section 4.2 (relating to sales, transfer and similar Taxes);

     (ii) assist the other party in preparing any Tax Returns which such other party is responsible for preparing and filing in accordance with paragraph (b) of this Section 4.2;

     (iii) cooperate fully in preparing for any audits of, or disputes with taxing authorities regarding, any Tax Returns of the Company;

     (iv) make available to the other and to any taxing authority as reasonably requested all information, records, and documents relating to Taxes of the Company;

     (v) provide timely notice to the other in writing of any pending or threatened Tax audits or assessments of the Company for taxable periods for which the other may have a liability under this Section 4.2; and

     (vi) furnish the other with copies of all correspondence received from any taxing authority in connection with any Tax audit or information request with respect to any such taxable period.

          (e) Notwithstanding anything to the contrary in this Agreement, each of the Sellers, jointly and severally, shall be liable for, and pursuant to Article V agrees to indemnify and hold harmless each Buyer Group Member from and against, any and all Losses and Expenses incurred by such Buyer Group Member in connection with or arising from Taxes imposed on each Seller as a result of the transactions contemplated by this Agreement.

          (f) Buyer agrees not to make any election under Section 338 of the Code with

39

respect to the purchase of the Shares pursuant to this Agreement without the approval of the Seller Representative which shall not be unreasonably withheld, provided that it shall not be unreasonable if Seller Representative withholds consent if the Sellers would incur a Tax liability as a result of such election by Buyer.

          (g) Notwithstanding anything to the contrary in this Agreement, the obligations of the parties set forth in this Section 4.2 shall be unconditional and absolute and shall remain in effect without limitation as to time.

          Section 4.3 Use of Name. Each of the Sellers agrees and covenants that from and after the Closing it shall not use the name “Vinci Systems” or a name which includes such name or the name “Vinci” or any variations of such names in connection with any activity conducted by it or any of its Affiliates.

          Section 4.4 Waiver. By execution hereof, the Company and each of the Sellers hereby waives any right of first refusal with respect to, or right to repurchase any, shares of the capital stock of the Company or the Options (or any shares issuable upon the exercise thereof), in each case in connection with the sale of the Shares and the cancellation and termination of the Options contemplated hereby.

          Section 4.5 Employee Benefit Plans. As soon as practicable after the Closing, Buyer shall provide, or shall cause to be provided, employee benefit plans, programs and arrangements to employees of the Company that are substantially similar to those made available to similarly situated employees of Buyer. Upon the inclusion of the employees of the Company in any benefits plan maintained or sponsored by Buyer or its Subsidiaries, including, without limitation, any plan or arrangement providing vacation benefits, each Company employee shall receive credit for service prior to the Closing Date with the Company to the same extent such service was counted under any similar or corresponding Buyer plans for the purposes of determining eligibility to participate, vesting and the level of benefits provided. If any such Company employee or their dependents are included in any medical, dental or health plan other than the plan or plans they participated in prior to the Closing Date, the Buyer Plan shall waive all limitations as to pre-existing conditions and waiting periods.

          Section 4.6 Operation of the Company. During the Performance Period, (i) the provisions set forth in Schedule 4.6 shall apply to the operations of the Company and (ii) Sellers shall not take any action inconsistent with such provisions.

          Section 4.7 Acceleration of Performance Conditions. In the event that, during the Performance Period, Buyer, without the consent of the Seller Representative (i) sells, transfers or assigns or otherwise disposes of the material assets of the Company that are necessary for the achievement of the Performance Conditions, in each case in a manner that deprives the Company of the use thereof, (ii) sells more than 50% of the outstanding capital stock of the Company to a party that is not an Affiliate of the Buyer, or (iii) prevents the Sellers from satisfying the Performance Conditions by breaching the covenant contained in Section 4.6, then it shall be deemed that the Sellers have satisfied any remaining Performance Conditions the time for satisfying which has not expired under Section 1.4 as of the date of the occurrence of one of the events described in clauses (i), (ii) and (iii) above.

40

ARTICLE V
INDEMNIFICATION

          Section 5.1 Indemnification by Sellers.

          (a) Each of the Sellers, jointly and severally, agrees to indemnify and hold harmless each Buyer Group Member from and against any and all Losses and Expenses incurred by such Buyer Group Member in connection with or arising from:

     (i) any breach, or alleged breach, by any Seller of, or any other failure of any Seller or any Restricted Person to perform, any of its covenants, agreements or obligations in this Agreement or in any other agreement executed and delivered by or on behalf of such Seller pursuant to this Agreement; and

     (ii) any breach, or alleged breach, of any warranty or the inaccuracy, or alleged inaccuracy, of any representation of Seller contained or referred to in this Agreement or any certificate or other document delivered by or on behalf of any Seller pursuant to this Agreement;

provided, however, without in any way limiting the Sellers’ indemnification obligations under clause (i) of Section 5.1(a) or under clause (ii) of Section 5.1(a) with respect to the Seller Designated Representations (as hereinafter defined), (x) the Sellers shall indemnify the Buyer Group Members under clause (ii) of Section 5.1(a) (other than with respect to the Seller Designated Representations as to which no such limitation shall apply) only in the event that the aggregate amount (without duplication) of Loss and Expense borne by the Buyer Group Members with respect thereto exceeds $150,000 but if in excess of such amount, then for the amount of such excess. Sellers’ aggregate indemnification liability under clause (ii) of Section 5.1(a) (other than with respect to the Seller Designated Representations as to which no such limitation shall apply) shall be an amount equal to twenty five percent (25%) of the Purchase Price. Each Seller’s (other than Mostafa Group, LLC, as to which this limitation shall not apply) indemnification liability under clause (ii) of Section 5.1(a) (other than with respect to the Seller Designated Representations as to which no such limitation shall apply) shall be an amount equal to twenty five percent (25%) of such Seller’s pro rata portion of the Purchase Price.

          (b) The indemnification provided for in clause (ii) of Section 5.1(a) shall terminate on June 30, 2006 (and no claims shall be made by Buyer under clause (ii) of Section 5.1(a) thereafter), except that the indemnification by the Sellers shall continue in any event as to:

     (i) any breach, or alleged breach, of any warranty or the inaccuracy, or alleged inaccuracy, of any representation of the Sellers set forth in Sections 2.1, 2.3, 2.4, 2.5, 2.21, 2.25, or 2.31 (together with Section 2.10, the “Seller Designated Representations”), as to which no time limitation shall apply, and any breach, or alleged breach, of any warranty or the inaccuracy, or alleged inaccuracy, of any representation of the Sellers set forth in Section 2.10, which shall survive for sixty (60) days after the expiration date of the applicable statute of limitations (including any extensions thereof);

41

and

     (ii) any Loss or Expense as to which Buyer has notified the Sellers in accordance with the provisions of Section 5.3 on or prior to the date such indemnification obligation would otherwise terminate in accordance with this Section 5.1, as to which the indemnification obligations of the Sellers shall continue until the liability of the Sellers shall have been determined pursuant to this Article V, and the Sellers shall have indemnified and reimbursed Buyer for the full amount of such Loss and Expense in accordance with this Article V.

          (c) If, at the time Buyer is obligated to make a Subsequent Cash Payment in accordance with Section 1.4 hereof, any Claim Notice given by a Buyer Group Member remains unresolved, Buyer shall be entitled to reduce the amount of such Subsequent Cash Payment by Buyer’s good faith reasonable estimate of the maximum aggregate amount of Loss and Expense exposure of the Buyer Group Member to matters reflected in all such unresolved Claim Notices, pending final determination of such matters. If it is finally determined that the Buyer Group Members were not entitled to the full amount of the indemnification reflected in such Claim Notices, Buyer shall promptly thereafter pay to the Seller Representative the appropriate portion of the applicable Subsequent Cash Payments that had been withheld together with Interest thereon. Otherwise Buyer shall retain such amount.

          Section 5.2 Indemnification by Buyer.

          (a) Buyer agrees to indemnify and hold harmless each Seller Group Member from and against any and all Losses and Expenses incurred by such Seller Group Member in connection with or arising from:

     (i) Any breach, or alleged breach, by Buyer of, or other failure of Buyer to perform, any of its covenants, agreements or obligations in this Agreement or in any other agreement executed and delivered by or on behalf of Buyer pursuant to this Agreement; or

     (ii) Any breach, or alleged breach, of any warranty or the inaccuracy, or alleged inaccuracy, of any representation of Buyer contained or referred to in this Agreement or in any certificate or other document delivered by or on behalf of Buyer pursuant hereto.

provided, however, without in any way limiting Buyer’ indemnification obligations under clause (i) of Section 5.2(a) or under clause (ii) of Section 5.2(a) with respect to the Buyer Designated Representations (as hereinafter defined), (i) the Buyer shall indemnify the Seller Group Members under clause (ii) of Section 5.2(a) (other than with respect to the Buyer Designated Representation as to which no such limitation shall apply) only in the event that the aggregate amount (without duplication) of Loss and Expense borne by the Seller Group Members with respect thereto exceeds $150,000 but if in excess of such amount, then for the amount of such excess, and (ii) Buyer’s aggregate indemnification liability under clause (ii) of Section 5.2 (other than with respect to the Buyer Designated Representation as to which no such limitation shall apply) shall be an amount equal to twenty five percent (25%) of the Purchase Price.

     (i) any breach, or alleged breach, of any warranty or the inaccuracy, or alleged inaccuracy, of any representation of Buyer set forth in Sections 3.1 and 3.3 (the “Buyer Designated Representations”), as to which no time limitation shall apply; and

     (ii) any Loss or Expense of which the Seller Representative has notified Buyer in accordance with the requirements of Section 5.3 on or prior to the date such indemnification would otherwise terminate in accordance with this Section 5.2, as to which the obligation of Buyer shall continue until the liability of Buyer shall have been determined pursuant to this Article V, and Buyer shall have reimbursed the Sellers for the full amount of such Loss and Expense in accordance with this Article V.

          Section 5.3 Notice and Determination of Claims and Forfeiture Events.

          (a) Any Buyer Group Member or Seller Group Member (the “Claiming Party”) seeking indemnification hereunder shall give to the party obligated to provide indemnification to such Claiming Party (the “Indemnifying Party”) and, in the case of any Buyer Group Member, the Escrow Agent, a notice (a “Claim Notice”) describing in reasonable detail the facts giving rise to any claim for indemnification hereunder 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 other agreement, document or instrument executed hereunder or in connection herewith upon which such claim is based; provided, that a Claim Notice in respect of any action at law or suit in equity by or against a third Person as to which indemnification will be sought shall be given promptly after the action or suit is commenced; provided further that failure to give such notice shall not relieve the Indemnifying Party of its obligations hereunder except to the extent it shall have been prejudiced by such failure. If the Claiming Party is a Buyer Group Member but is not Buyer, the Claim Notice must be accompanied by a certificate from Buyer confirming that the such Claiming Party is a Buyer Group Member.

          (b) In the event of Claim Notice by a Buyer Group Member, unless the Seller Representative shall have delivered an Objection in accordance with Section 5.3(c), the Escrow Agent shall, on the twentieth day (or such earlier day as the Seller Representative shall authorize in writing to the Escrow Agent) after receipt of a Claim Notice with respect to indemnification for a specified amount, deliver to Buyer, for its account or for the account of each Buyer Group Member named in the Claim Notice, such portion of the Cash Escrow Fund, valued in accordance with the Escrow Agreement, with a value equal to the specified amount.

          (c) Until the twentieth day following delivery of a Claim Notice, the Seller Representative may deliver to the Escrow Agent a written objection (an “Objection”) to the claim made in such Claim Notice. At the time of delivery of any Objection to the Escrow Agent, a duplicate copy of such Objection shall be delivered to the Claiming Party.

43

          (d) Upon receipt of an Objection properly made to a Claim Notice, the Escrow Agent shall (i) deliver to Buyer, for its account or for the account of each Buyer Group Member named in the Claim Notice, such portion of the Cash Escrow Fund, valued in accordance with the Escrow Agreement, with a value equal to that portion of the amount subject to the Claim Notice, if any, which is not disputed by the Seller Representative and (ii) designate and segregate out of the assets of the Cash Escrow Fund a portion thereof, valued in accordance with the Escrow Agreement, with a value equal to the amount subject to the Claim Notice which is disputed by the Seller Representative. Thereafter, the Escrow Agent shall not dispose of such segregated portion of the Cash Escrow Fund until the Escrow Agent shall have received a certified copy of the final decision of the arbitrators as contemplated by Section 5.4, or the Escrow Agent shall have received a copy of the written agreement between the Claiming Party and the Seller Representative resolving such dispute and setting forth the amount, if any, which such Claiming Party is entitled to receive.
