a) does or would or might reasonably be expected to cause or constitute a material breach of any of the Warranties, other than as disclosed in the Disclosure Letter in accordance with the provisions of this agreement; or

b) would or might reasonably be considered to give rise to a Tax Claim or claim under the indemnity in clause 23 hereof;

he will promptly give written notice of such event to the Purchaser before Completion with sufficient details (as known at that time by the Warrantor) to enable the Purchaser to assess accurately the impact of such event and if so requested by the Purchaser to use all reasonable endeavours promptly to prevent or remedy the same; and

24.1.3 during the period from the date of this agreement until Completion the business of the Company shall be carried on in the ordinary and normal course to maintain the same as a going concern.

then in either case:

if such breach or breaches would have a material adverse affect on the business of any Group Company (which solely for the purposes of this clause 24.2 shall mean having a financial affect in aggregate of £100,000 or more (excluding costs and interest)) or which affects the ability of the Vendors and/or the Option Holders to sell and transfer all the Shares pursuant to the terms of this agreement then the Purchaser shall at any time prior to Completion be entitled to rescind this agreement by notice in writing to the Vendors and the Option Holders.

The right of rescission granted to the Purchaser in clause 24.2 is in addition to any right of rescission of the Purchaser under any statute or at common law.

16.3 Within the seven years commencing before the date hereof no Group Company has been the subject of any non-routine investigation, audit or discovery by or involving any investigation unit of any Tax authority, and no Group Company has paid or become liable to pay any penalty, surcharge, fine or interest in respect of Tax, and there are no existing circumstances which make it likely that a Group Company will, in the foreseeable future, be so subject, or will incur any such liability.

3.1 If the Purchaser or a Group Company receives a Claim for Tax which appears to any of them to be relevant for the purposes of this schedule or in relation to the Utilised Tax Losses, the Purchaser or the Group Company shall as soon as reasonably practicable (and in any event in the case of the receipt of a Claim for Tax consisting of any assessment or demand for Tax or for which the time for response or appeal is limited not less than 10 Business Days prior to the day on which the time for response or appeal expires) give written notice thereof to the Covenantor setting out reasonable details of the Claim for Tax or claim in relation to the Utilised Tax Losses provided that the giving of such notice shall not be a condition precedent to the liability of the Covenantor under this schedule.

3.2 If the Covenantor shall indemnify and secure (provided that security will only be required in the event that any outstanding liabilities of the type contemplated by this clause incurred by any Group Company and/or the Purchaser (as the case may be) exceeds £20,000) the Group Company and/or (as the case shall require) the Purchaser to the Purchaser’s reasonable satisfaction against all liabilities, costs, damages, Tax, additional Tax or expenses which may be incurred thereby within 15 Business Days of the date of the notice to the Covenantor specified in paragraph 3.1 above, the Purchaser shall and shall procure that the relevant Group Company shall (except where fraudulent, negligent or criminal conduct is alleged) take such lawful action as the Covenantor may reasonably request by notice in writing given to the Purchaser to avoid, dispute, defend, resist, appeal or compromise any Claim for Tax or claim in relation to the Utilised Tax Losses (such a Claim for Tax or claim in relation to the Utilised Tax Losses where action is so requested being hereinafter referred to as a “Dispute”) provided that:

3.2.1 neither the Group Company nor the Purchaser shall be obliged to appeal or procure an appeal against any Claim for Tax or claim in relation to the Utilised Tax Losses raised on either of them if, the Covenantor having been given written notice of the receipt of such assessment, the Group Company and the Purchaser have not within 20 Business Days of the date of the notice received instructions in writing from the Covenantor to do so or the Covenantor failed to indemnify or (if applicable) secure the Group Company and/or the Purchaser (as appropriate);

3.2.2 where the Liability for Tax the subject of the Dispute is required to be paid as a precondition to an appeal or before any other action requested by the Covenantor may be taken, the Group Company shall not be obliged to take any such action until the Covenantor shall have paid to the Purchaser or the Group Company an amount equal to such Liability for Tax for the purpose of discharging the same;

4 PAYMENT DATE

4.1 Where the Covenantor is liable to the Purchaser pursuant to the covenant contained in paragraph 2 above:

4.1.1 in a case that involves an actual payment of Tax the Covenantor shall pay sums due under this schedule in cleared funds without any deduction whatsoever by way of set-off or counter-claim or otherwise, 3 Business Days prior to the date on which the Tax in question would have had to have been paid in order to prevent a liability to interest or a fine, charge, penalty or surcharge from arising in respect of the Liability for Tax in question or, as the case may be, 3 Business Days prior to the date on which the Tax in question must be paid in order to entitle the Group Company or the Purchaser to make an appeal against an assessment to Tax;

5 TAXATION OF CLAIMS

5.1 Subject to paragraph 5.2, all payments made by the Covenantor pursuant to this schedule in respect of any Liability for Tax shall be made gross, free of any rights of counterclaim or set-off and without any deduction or withholding of any nature other than a deduction or withholding required by law.

5.2 If the Covenantor makes any deduction or withholding (including Tax) required by law from any payment under this schedule then the sum due from the Covenantor in respect of the payment shall be increased to the extent necessary to ensure that after the making of any such deduction or withholding the Purchaser (or, as the case may be, the relevant Group Company) receives and retains a sum equal to the sum it would have received and retained had no deduction or withholding been required to be made.

5.3 If any sum (the “first sum”) payable by the Covenantor to the Purchaser under this schedule shall be subject to Tax in the hands of the Purchaser or would have been taxable in the hands of the Purchaser assuming that the Purchaser had sufficient taxable profits to use all Reliefs available to it in the accounting period in which it receives a sum under this schedule then the Covenantor shall pay to the Purchaser (as often as shall be necessary) such additional sum or sums as will after such Tax (and any Tax on such additional sum or sums) leave the Purchaser with such amount as the Purchaser would have been left with had the first sum not been subject to Tax in the hands of the Purchaser.

9.2 The amount of the Overprovision shall be calculated on the basis that no Overprovision will arise or be increased by any Purchaser’s Relief.

11.3 The Covenantor shall have conduct of all matters (including dealing with all negotiations and correspondence) relating to the Tax Documents provided that the Covenantor shall not (and shall procure that its agents shall not) agree any matter with a Tax Authority which is likely to affect to any extent the future liability to Taxation of any Group Company or of the Purchaser without the prior written consent of the Purchaser (such consent not to be unreasonably withheld or delayed).

11.4 The Covenantor shall not (and shall procure that its agents shall not) submit any document which comprises or includes a claim, election, disclaimer, surrender, notice or consent, or withdraw any such item, unless the making, giving or withdrawal of it either:

1.6 The Purchaser will take or procure the taking of all such reasonable steps as are required by law in order to mitigate any Warranty Claim.
