6.7.1 to terminate this Agreement (other than Clauses 1, 5.5, 11 and 12.2 to 12.15) without liability on its part or on the part of those on whose behalf notice is served whereupon, (i) in the case of such non-compliance by any of the Sellers, the amounts referred to in Clauses 5.5.2(x), (y) and (z) shall become payable or (ii) in the case of such non-compliance by any of the Purchasers, the amounts referred to in Clause 5.5.4 shall become payable; or

6.7.3 to fix a new date for the relevant Closing (not being more than 20 Business Days after the agreed date for the relevant Closing) in which case the provisions of Schedule 6

shall apply to the relevant Closing as so deferred but provided such deferral may only occur once.

6.8 Books and Records

The Purchasers shall and shall procure that the Group Companies shall, retain for a period of twelve months from First Closing or such longer period as is necessary for the Sellers to close their books and file their tax returns for 2005 and allow the Sellers or the Sellers’ representatives to have reasonable access (at all reasonable times during normal business hours and on reasonable advance notice) to (and at the Sellers’ expense, copies of) the books, records and documents relating to the Group, to the extent that they relate to the period prior to the relevant Closing and to the extent reasonably required by the Sellers to comply with any relevant law or regulations or in connection with the preparation and agreement of any accounting, tax or other records.

6.9 Schipol Lease

6.9.1 From the date of this Agreement, the Seller shall use its reasonable endeavours to procure the assignment of the rights and obligations under the Schipol Lease to a third party, such assignment to constitute a full release of VIA Nederland from all rights and obligations under the Schipol Lease. The Seller shall keep the Purchasers informed as to efforts undertaken pursuant to this Clause 6.9.1 and shall promptly provide notice to the Purchasers of each Schipol Assignment. The Purchasers shall provide all reasonable assistance and information as the Seller may reasonably require in connection with any proposed Schipol Assignment.

Such amounts shall be paid to the Schipol Lessor in accordance with the terms of the Schipol Lease.

6.9.3 Upon any third party entering into a Schipol Assignment, the Purchasers shall promptly pay to the Seller (or procure the payment of) an amount equal to the Deferred Amount multiplied by a fraction, the numerator of which is aggregate value of all rent payments to be made pursuant to the terms of the Schipol Assignment to the expiration date of the Schipol Lease and the denominator of which is the aggregate value of all rent payments to be made pursuant to the terms of the Schipol Lease until its expiration date.

6.9.4 Any such payment by the Purchasers shall be made in Euro. Any such payment shall be treated as a reduction of the Deferred Amount, until the Deferred Amount shall have been reduced to zero. At such time, subject to release of all restrictions over the Blocked Account, the Purchasers shall cooperate with and provide all such reasonable assistance as the Seller may reasonably require in connection with the release of 50% of the Blocked Amount from the Blocked Account by the Schipol Lessor to the order of the Seller.

6.9.5 If at any time prior to Second Closing there shall be one or more Schipol Assignments constituting a full assignment of the rights and obligations of VIA Nederland under the Schipol Lease to a B Group Company and releasing VIA Nederland from all rights and obligations under the Schipol Lease, the Purchasers shall cooperate with and, subject to release of all restrictions over the Blocked Account, provide all such reasonable assistance as the Seller may reasonably require in connection with the release of 50% of the Blocked Amount from the Blocked Account by the Schipol Lessor to the order of the Seller, provided that unless prior to Second Closing there has been a subsequent assignment of the Schipol Lease to a person which is not a B Group Company such that the relevant B Group Company is released from all rights and obligations under the Schipol Lease, there shall be withheld by the Purchasers from the payment of the Second Closing Purchase Price an amount equal to the aggregate of (i) the amount released from the Blocked Account to the order of the Seller pursuant to Clause 6.9.4 and (ii) the amount of outstanding liabilities under the Schipol Lease at the relevant time (calculated on a basis consistent with that used by the parties for the purposes of calculating such liability at the time the Restatement and Amendment Agreement was entered into) and the provisions of Clauses 6.9.1 and 6.9.3 shall apply mutatis mutandis in relation to the amount so withheld.

6.9.6 Notwithstanding the foregoing provisions, if the assignee of the Schipol Lease is a B Group Company, no part of the Deferred Amount shall become payable to the Sellers prior to 5 August 2005.

6.9.7 In the event that the Schipol Lease is partially assigned and the outstanding liabilities of the Seller in relation to the Schipol Lease amount to less than 50% of the Blocked Amount, then the Seller shall be entitled to draw from the Blocked Account in an amount up to 50% of the Blocked Amount in order to satisfy such outstanding liabilities.

6.10 Schuberg Contract

In the event of termination of the Schuberg Contract at any time prior to the Back-Stop Date, the Purchaser agrees to procure the transfer to the Seller of all hardware (i) that is located at the Schuberg premises, (ii) that is used in connection with the services provided by Schuberg Philis B.V. pursuant to the Schuberg Contract or (iii) to which VIA Nederland has any right as a result of such termination.

Contracts
(Clause 2.3.1(iv))

1 Obligation to obtain Third Party Consents

In relation to any Contract which is not assignable without a Third Party Consent, this Agreement shall not be construed as an assignment or an attempted assignment and the Relevant Sellers and the Relevant Purchasers shall each use reasonable endeavours both before and after the relevant Closing to obtain all necessary Third Party Consents on terms reasonably acceptable to the Relevant Purchasers and the Relevant Sellers as soon as possible and shall keep each other informed of progress in obtaining such Third Party Consents. The Relevant Sellers shall deliver to the Relevant Purchasers, on the relevant Closing or, if later, as soon as possible after receipt, any Third Party Consent and an assignment duly executed by the appropriate parties.

2 Obligations until Third Party Consents are obtained/where Third Party Consents are refused

2.1 Subject to paragraph 2.2, the Relevant Purchasers shall, from the relevant Closing, assume, carry out, perform and discharge the Relevant Seller’s obligations under the Contracts and shall indemnify and keep indemnified the Relevant Seller against any Liability incurred by that Seller or any member of the VIA Group arising from the failure by the Relevant Purchaser to assume, carry out, perform or discharge such obligations and against any Losses which that Seller may suffer by reason of that Seller taking any reasonable action to avoid, resist or defend any Liability referred to in this paragraph and provided that the Relevant Purchaser shall only be liable to the extent such Liability incurred by that Seller is a Liability which is intended to be assumed by the Relevant Purchaser pursuant to Clause 2.3.2.

2.2 In respect of any Contract, from the relevant Closing until the relevant Third Party Consent has been obtained, as contemplated by paragraph 1.1, or where the Third Party Consent has been refused and until the earlier to occur of (i) the date on which trading of VIA Inc’s common stock on NASDAQ and Euronext ceases and (ii) VIA Inc having completed a distribution to the VIA Shareholders:

2.2.1 the Relevant Seller shall hold on trust such Contract and any monies, goods or other benefits received under such Contract to the extent it is lawfully able to do so or, where it is not lawfully able to do so or where holding on trust is not possible under local law, that Seller and the Relevant Purchaser shall make such other arrangements between themselves to provide to the Relevant Purchaser the benefits of the Contract, including the enforcement at the cost and for the account of the Relevant Purchaser of all rights of the relevant Seller against any other party thereto;

2.2.2 to the extent that the Relevant Purchasers are lawfully able to do so, and subject to the Relevant Purchasers receiving the benefits of the Contract, the Relevant Purchasers shall at their own expense perform the Relevant Seller’s obligations under the Contract as agent or sub-contractor and shall indemnify the Relevant Seller in respect thereof. To the extent that the Relevant Purchasers are not lawfully able to do so, the Relevant Seller shall, at the Relevant Purchasers’ cost do all such things as the Relevant Purchasers may reasonably require to enable due performance of the Contract;

provided that, in each case, the Relevant Purchasers shall indemnify and keep indemnified the Relevant Seller or member of the VIA Group against any liability incurred by the Relevant Seller or any member of the VIA Group as a result of this paragraph 2.2.

3 Failure to Obtain Third Party Consents

If a Third Party Consent is refused or otherwise not obtained on terms reasonably acceptable to the Relevant Purchasers within three (3) months of Second Closing (or, if Second Closing does not occur, First Closing), references in this Agreement to the Contracts and the VIA Operations (other than in this paragraph 3) shall be construed as excluding such Contract.

4 Novation

To the extent that the Sellers request the novation of any Contract to a Group Company or a member of the Purchaser’s Group, the parties shall use their reasonable endeavours to novate such Contract pursuant to Clause 2.3 and pending such novation, the provisions of this Schedule 3 shall apply.

2 Application of Transfer Provisions

2.1 If any contract of employment, employment relationship or collective agreement in relation to any employee (other than a Relevant Employee) employed by either of the Sellers, the other members of the VIA Group or any Group Company shall have effect as if originally made between the Relevant Purchasers and such employee (a “Transferred Employee”) as a result of

the Transfer Provisions (without prejudice to any other rights or remedies which may be available to the Relevant Purchasers):

2.1.1 the Relevant Purchaser shall, upon becoming aware of the application of the Transfer Provisions to any such contract of employment or collective agreement, notify the Seller forthwith and the Seller or any other member of the VIA Group shall procure that such employees enter into settlement agreements with the Relevant Sellers and the Relevant Purchaser on termination of the Transferred Employee’s employment (on terms that the Sellers are liable for all payments due to such Transferred Employees). The Relevant Purchaser shall co-operate with the Sellers and take all reasonable steps to assist the Sellers in procuring that such Transferred Employees enter into termination agreements as soon as reasonably practicable following the relevant Closing; and

2.1.2 the Sellers shall indemnify the Relevant Purchasers and keep the Relevant Purchasers indemnified against all Liabilities relating to or arising out of such termination or the transfer of Transferred Employees (including any Liability arising out of a failure by the Sellers but excluding any Liability arising out of a failure by the Purchasers to comply with their obligations under the Transfer Provisions) and shall reimburse the Relevant Purchasers for all costs, emoluments and expenses (including, without limitation, any taxation and employer’s national insurance contributions) reasonably and properly incurred in employing such Transferred Employee in respect of his employment on or after the relevant Closing Date; and

2.1.3 irrespective of whether the Transferred Employee’s employment is terminated in accordance with paragraph 2.1.1 above, the Sellers will indemnify the Relevant Purchasers and keep the Relevant Purchasers indemnified against any Liabilities which relate to, arise out of or are connected with any claims brought against the Relevant Purchaser by any Transferred Employee other than in each case as a result of breach by the Relevant Purchaser of its obligations under paragraph 2.1.1 above which are due solely to any act or omission by either of the Sellers, any other member of the VIA Group or any Group Company or any event, matter or any other occurrence having its origin prior to the relevant Closing Date and which the Relevant Purchasers incurs in relation to any contract of employment, or the employment relationship or collective agreement of one or more of the Transferred Employees pursuant to the Transfer Provisions and/or in respect of this Agreement.

2.2 The Sellers shall indemnify the Relevant Purchasers and keep the Relevant Purchasers indemnified against all Liabilities which relate to or arise out of any dismissal by the Sellers, the VIA Group or any Group Company of any employee (not being a Relevant Employee) and which the Relevant Purchasers may incur pursuant to the provisions of the Transfer Provisions and this Agreement.

3 Definitions

VAT

1 The Sellers and the Purchasers shall use all reasonable endeavours (including, where appropriate, the making of an election or application in respect of VAT to any Taxation Authority or entering into a written agreement) to secure that the sale of the Group so far as carried on in the European Union is treated as neither a supply of goods nor a supply of services for the purposes of the laws governing VAT in the relevant member state.

2 To the extent that any state outside the European Union provides for relief or exemption from VAT (or any similar tax on turnover or added value) on the transfer of a business or a company or treats such a transaction as being non-taxable for VAT purposes, the Sellers and the Purchasers shall use all reasonable endeavours (including, where appropriate, the making of an election or application in respect of VAT (or any similar tax on turnover or added value) to any Taxation Authority or entering into a written agreement) to secure such treatment as regards the sale of the Group (insofar as the business of the Group is carried on in the relevant state) under this Agreement.
