If Purchaser does not deliver a Statement of Objections to Seller within such thirty-day period, the Statement shall become final and binding upon the parties. If Purchaser delivers a Statement of Objections to Seller within such thirty-day period, and the parties cannot resolve any such objection within ten (10) Business Days after the receipt by Seller of such Statement of Objections, any remaining disputes shall be resolved by Ernst & Young LLP (the “Accounting Firm”).

The resolution of disputes by the Accounting Firm shall be set forth in writing and shall be conclusive and binding upon the parties, and the Statement, as modified by such resolution, shall become final and binding upon the date of such resolution. The determination of the Accounting Firm for any item in dispute cannot be in excess of, nor less than, the greatest or lowest value, respectively, claimed for that particular item in the Statement, in the case of Seller, or in the Statement of Objections, in the case of Purchaser. The Accounting Firm shall have no right to make any determination with respect to the undisputed portions of the Statement, and no such determination with respect to the undisputed portions of the Statement shall be binding on Seller or Purchaser. The Accounting Firm shall be instructed to calculate Net Cash in accordance with Section 2.03. The fees and expenses of the Accounting Firm shall be apportioned between Seller and Purchaser by the Accounting Firm based on the degree to which Seller’s and Purchaser’s claims were unsuccessful and shall be paid by Seller and Purchaser in accordance with such determination.

(c) Upon the Statement becoming final and binding in accordance with Section 2.04(b), the Initial Purchase Price shall be increased by fifty percent (50%) of the amount by which the Closing Net Cash exceeds the Estimated Closing Net Cash or decreased by fifty percent (50%) of the amount by which the Closing Net Cash is less than the Estimated Closing Net Cash. If the Closing Net Cash exceeds the Estimated Closing Net Cash, Purchaser shall pay to Seller fifty percent (50%) of the amount of such excess, together with a sum equivalent to interest thereon at a rate equal to the LIBOR Rate from the Closing Date to the date of payment. If the Estimated Closing Net Cash exceeds the Closing Net Cash, Seller shall pay to Purchaser fifty percent (50%) of the amount of such excess, together with a sum equivalent to interest thereon at a rate equal to the LIBOR Rate from the Closing Date to the date of payment. Any such payment hereunder shall be made in accordance with Section 9.04 within five (5) Business Days after final determination of the Statement to an account designated in writing by Purchaser or Seller, as the case may be.
