The total adjustment amount shall be calculated pursuant to the following formula (the "ADJUSTMENT AMOUNT"): If, (i) (ASV- NCV) * 12 < CHF 1,000,000 means no adjustment of Purchase Price ii) (ASV-NCV) * 12 > or equal to CHF 1,000,000 means a price adjustment of (ASV- NCV)* 12 will be deducted from the Purchase Price Whereby: ASV shall mean the actual monthly sales volume of all Customers who have or have been given notice of termination of their agreement with the Company or have been disconnected (other than for reasons of maintenance or temporary service outage) during the Adjustment Period (the "TERMINATED CUSTOMERS").

Within 20 (twenty) Business Days following Closing, Seller shall deliver to Purchaser a calculation of the adjustment, if any, together with copies of the relevant documentation supporting such calculation. Prior to such delivery, Seller shall so far as practicable consult with Purchaser with a view to eliminating any potential disagreement. Within 20 (twenty) Business Days following the delivery to Purchaser of Seller's notification and absent Purchaser notifying Seller within such period as to any dispute it may have as to Seller's determination, the Adjustment Amount calculated pursuant to this Section 2.3 shall be paid to Purchaser in cash from the Escrow Amount in accordance with the Escrow Agreement.

The costs and expenses (including VAT) of the Independent Accountant shall be borne by Seller and Purchaser in equal shares. For the purposes of the calculation of the Adjustment Amount by Seller under this Section 2.3, Purchaser acknowledges that on and from Closing (a) Seller is entitled to retain copies of the relevant documentation supporting the calculation of the Adjustment Amount, which shall be kept strictly confidential and (b) should Seller request, Purchaser shall procure that Seller is given reasonable access (during normal business hours) to the management and documents of the Company to the extent necessary or reasonable to Seller to verify the determination by the Independent Accountant. 3 REPRESENTATIONS AND WARRANTIES OF SELLER AND VHB Subject to the limitations set forth in the Agreement, Seller and VHB hereby represent and warrant to Purchaser as of the date of this Agreement and as of the Closing Date the following matters except that those representations and warranties which are explicitly made as of a specific date shall be true and correct only as of such date.
