               (a) Within sixty (60) calendar days after the Closing Date, the Buyer shall deliver to the Sellers’ Representative a statement (the “ Statement ”) of the Closing Working Capital and the Assumed Indebtedness, in each case prepared in accordance with the Balance Sheet Rules.

During the thirty (30)-day period following the delivery of a Notice of Disagreement, the Sellers’ Representative and the Buyer shall seek in good faith to resolve in writing any differences that they may have with respect to the matters specified in the Notice of Disagreement. If at the end of such thirty (30)-day period the Sellers’ Representative and the Buyer have not resolved in writing the matters specified in the Notice of Disagreement, the Sellers’ Representative and the Buyer shall submit to an independent accounting firm (the “ Accounting Firm ”) for arbitration, in accordance with the standards set forth in this Section 2.3(b) , only such matters specified in the Notice of Disagreement that remain in dispute.

The Sellers’ Representative and the Buyer shall use reasonable efforts to cause the Accounting Firm to render a written decision resolving the matters submitted to the Accounting Firm within thirty (30) calendar days of the receipt of such submission. The scope of the disputes to be resolved by the Accounting Firm shall be limited to fixing mathematical errors and determining whether the items in dispute were determined in accordance with the Balance Sheet Rules and the Accounting Firm is not to make any other determination, including any determination as to whether the Base Amount, Working Capital Estimate or the Estimated Assumed Indebtedness are correct. The Accounting Firm’s decision shall be based solely on written submissions by the Sellers’ Representative and the Buyer and their respective representatives and not by independent review and shall be final and binding on all of the parties hereto. The Accounting Firm may not assign a value greater than the greatest value for such item claimed by either party or smaller than the smallest value for such item claimed by either party.

The fees and expenses of the Accounting Firm incurred pursuant to this Section 2.3(b) shall be borne pro rata as between the Sellers, on the one hand, and the Buyer, on the other hand, in proportion to the final allocation made by such Accounting Firm of the disputed items weighted in relation to the claims made by the Sellers’ Representative and the Buyer, such that the prevailing party pays the lesser proportion of such fees, costs and expenses.

          (c) For the purposes of this Agreement, “ Final Working Capital ” means the Closing Working Capital and “ Final Assumed Indebtedness ” means the Assumed Indebtedness, in each case as finally agreed or determined in accordance with Section 2.3(b) . The Estimated Purchase Price shall be increased (any such increase, the “ Seller Adjustment

Amount ”) by the sum of (i) the amount, if any, that the Final Working Capital exceeds the Working Capital Estimate and (ii) the amount, if any, that the Estimated Assumed Indebtedness Amount exceeds the Final Assumed Indebtedness. The Estimated Purchase Price shall be decreased (any such decrease, the “ Buyer Adjustment Amount ”) by the sum of (i) the amount, if any that the Working Capital Estimate exceeds the Final Working Capital and (ii) the amount, if any, that the Final Assumed Indebtedness exceeds the Estimated Assumed Indebtedness Amount. If the Seller Adjustment Amount exceeds the Buyer Adjustment Amount, the Buyer shall, within five (5) Business Days after the Final Working Capital and the Final Assumed Indebtedness are determined, make payment by wire transfer of immediately available funds to the Sellers and the Optionholders in accordance with their respective Adjustment Amount Transaction Percentage in the amount of any such excess; provided, that, notwithstanding anything to the contrary contained herein, any portion of the Seller Adjustment Amount attributable to a Special Adjustment shall be payable in either cash or Buyer’s Stock (which shall be valued at the Closing Date Value), in the Buyer’s sole and absolute discretion. If the Buyer Adjustment Amount exceeds the Seller Adjustment Amount, the parties shall, within five (5) Business Days after the Final Working Capital and the Final Assumed Indebtedness are determined, cause the Escrow Agent to release a wire transfer of immediately available funds to the Buyer from the Purchase Price Adjustment Escrow Fund in an amount equal to any such excess in accordance with the terms of the Escrow Agreement; provided that in the event such payment amount exceeds the amount of the then available Purchase Price Adjustment Escrow Fund, the shortfall shall be paid from the available Indemnity Escrow Fund.

          (d) No actions taken by the Buyer on its own behalf or on behalf of the Company or any Company Subsidiary, on or following the Closing Date shall be given effect for purposes of determining the Closing Working Capital or Assumed Indebtedness. During the period of time from and after the Closing Date through the final determination and payment of Closing Working Capital and Assumed Indebtedness in accordance with this Section 2.3 , the Buyer shall afford, and shall cause the Company and each Company Subsidiary to afford, to the Sellers and any accountants, counsel or financial advisers retained by the Sellers in connection with the review of Closing Working Capital and Assumed Indebtedness in accordance with this Section 2.3 , direct access during normal business hours upon reasonable advance notice to all the properties, books, contracts, personnel, representatives (including the Company’s accountants) and records of the Company, each Company Subsidiary and such representatives (including the work papers of the Company’s accountants) relevant to the review of the Statement and the Buyer’s determination of Closing Working Capital and Assumed Indebtedness in accordance with this Section 2.3 .

     2.4 Treatment of Options . Immediately prior to the Closing, the Sellers shall cause the Company to take all actions necessary so all Options then outstanding shall become fully vested and exercisable (whether or not currently exercisable) and, immediately prior to the Closing, each Option not theretofore exercised shall be cancelled without any future liability to the Buyer, the Company or any other Person after the Closing, in exchange for the right to receive the payment described in the following sentence (such payments in the aggregate, the “ Aggregate Option Consideration ”). The Company shall cause each Optionholder exercising any Options prior to the Closing to agree in writing to become a party to this Agreement as a Seller and to be bound by, and subject to, all of the covenants, terms and conditions of this Agreement that are binding upon the Sellers and the Annexes attached hereto shall be deemed to

have been updated without any further action of the parties hereto to reflect that each such Optionholder has become a Seller. Subject to the other provisions of this Section 2.4 , each holder of an Option that is cancelled pursuant to this Section 2.4 shall, in respect of each such Option, be entitled to a cash payment in an amount equal to the product of (I) the excess, if any, of (i) the quotient obtained by dividing (A) the Estimated Purchase Price plus the aggregate exercise price of all Options outstanding as of the time of cancellation by (B) the sum of the total number of Shares outstanding as of the Closing (after giving effect to the Option Cancellation) and the number of shares of Common Stock subject to all Options outstanding at the time of cancellation over (ii) the applicable Exercise Price of each Option, multiplied by (II) the number of shares of Common Stock underlying such Options. The Company shall be entitled to, and the Buyer will cause the Company at the Closing to, deduct and withhold from the amounts otherwise payable pursuant to this Section 2.4 to any Optionholder such amounts (the “ Withholding Amounts ”) as the Company is required to deduct and withhold in connection with the exercise of the underlying Option or with respect to the making of such payment under the Code, or any provision of state, local or foreign tax law and to properly remit such amount to the appropriate Tax authority.
