disclosed in sufficient detail to enable a reasonable purchaser to identify the nature of the matter disclosed and provided that the Sellers are under no obligation to have brought to the Relevant Purchasers’ attention any specific matter documented in the Data Room.

8.3 Updating of the Warranties to Closing

Subject to Clause 8.2, including without limitation the Disclosure Letter and the Data Room as updated as at Closing, the Sellers further warrant to the Relevant Purchasers that the Warranties will be true and accurate at Closing as if they had been repeated at Closing by reference to the facts and circumstances then existing and on the basis that any reference in the Warranties, whether express or implied, to the date of this Agreement is substituted by a reference to the Closing Date provided always that the Purchasers’ sole remedy for any breach of any such Warranties shall be as set out in Clause 5.5.1.

8.4 The Sellers’ Waiver of Rights against the Group

(iii) the Relevant Purchasers have full corporate power and authority to enter into and perform their obligations under this Agreement and each document to be entered into pursuant hereto and all actions have been taken by them which are necessary for them to execute and perform their obligations under this Agreement and each document to be entered into pursuant hereto;

(b) any change after Closing of any generally accepted interpretation or application of any legislation.

Pending Closing no announcement or circular in connection with the existence or the subject matter of this Agreement or any agreement to be entered into pursuant hereto shall be made or issued by or on behalf of any member of the VIA Group or the Purchasers’ Group (including for the purposes of this Clause 11.1, any holding company (as defined in the Companies Act 1985) of the Purchaser or a subsidiary of a holding company of the Purchaser) without the prior written approval of VIA Inc and the Purchaser, such approval not to be unreasonably withheld, delayed or conditioned. This shall not affect any announcement or circular required by law or any regulatory body or the rules of any recognised stock exchange on which the shares of either party are listed but the party with an obligation to make an announcement or issue a circular shall consult with the other parties insofar as is reasonably practicable before complying with such an obligation.

11.2 Confidentiality

The Confidentiality Agreement shall cease to have any force or effect from Closing.

12.2 Whole Agreement

12.2.1 This Agreement contains the whole agreement between the parties relating to the subject matter of this Agreement at the date hereof to the exclusion of any terms implied by law which may be excluded by contract and supersedes any previous written or oral agreement between the parties in relation to the matters dealt with in this Agreement.

12.4 Reasonableness

12.5 Third Party Rights

A person who is not a party to this Agreement has no right under the Contracts (Rights of Third Parties) Act 1999 to enforce any term of, or enjoy any benefit under, this Agreement.

No variation of this Agreement shall be effective unless in writing and signed by or on behalf of each of the parties.

12.7.2 the Purchasers shall bear all such costs incurred by them in connection with the preparation, negotiation and execution of this Agreement and the purchase of the Group.

12.8 Interest

If any party defaults in the payment when due of any sum payable under this Agreement, (howsoever determined) the liability of that party shall, save as otherwise expressly provided, be increased to include interest on such sum from the date when such payment is due until the date of actual payment (as well after as before judgment) at a rate per annum of two per cent above the base rate of LIBOR for monthly deposits. Such interest shall accrue from day to day.

12.9 Grossing-up of Indemnity Payments, VAT

12.9.1 All sums payable under this Agreement pursuant to an indemnity, compensation or reimbursement provision shall be paid free and clear of all deductions, withholdings, set-offs or counterclaims whatsoever save only as may be required by law. If any deductions or withholdings are required by law the party making the payment shall (except to the extent such sums comprise interest) be obliged to pay to the other party such sum as will after such deduction or withholding has been made leave the other party with the same amount as it would have been entitled to receive in the absence of any such requirement to make a deduction or withholding.

12.9.2 Where any payment is made under this Agreement pursuant to an indemnity, compensation or reimbursement provision and that sum is subject to a charge to Taxation in the hands of the recipient (other than Taxation attributable to a payment being properly treated as an adjustment to the consideration paid by the Relevant Purchaser for the Group) the sum payable shall be increased to such sum as will ensure that after payment of such Taxation (and after giving credit for any tax relief available to the recipient in respect of the matter giving rise to the payment) the recipient shall be left with a sum equal to the sum that it would have received in the absence of such a charge to taxation.

12.9.3 Where any sum constituting an indemnity, compensation or reimbursement to any party to this Agreement (the “Party”) is paid to a person other than the Party but is treated as taxable in the hands of the Party, the payer shall promptly pay to the Party such sum as shall reimburse the Party for all Taxation suffered by it in respect of the payment (after giving credit for any tax relief available to the Party in respect of the matter giving rise to the payment).

12.10 Permitted assignment and nomination of Purchasers

12.10.2 The Purchaser shall be entitled by giving not less than two Business Days’ notice before the Closing to nominate a wholly-owned subsidiary to assume the rights and

obligations of a Relevant Purchaser under this Agreement provided that the Purchaser shall remain jointly and severally liable under this Agreement.
