LIMITATIONS ON LIABILITY 6.1 This Clause 6 limits the liability of the Minority Sellers in relation to any Claim. 6.2 The maximum aggregate liability of the Minority Sellers in respect of all Claims and in respect of any indemnity or other undertaking to pay any amount under this Agreement (as the case may be) will not exceed an amount equal to the aggregate Purchase Price actually received by the Minority Sellers and the maximum aggregate liability of each Minority Seller in respect of such Claims and in respect of any indemnity or other undertaking to pay any amount under this Agreement (as the case may be) will not exceed such Minority Seller’s proportion of the Purchase Price actually received by that Minority Seller. 6.3 The Minority Sellers shall not be liable for a Claim unless notice in writing (specifying in reasonable detail the basis of the Claim (in so far as is known to the Purchaser) and, so far as is practicable, the amount claimed in respect of it) has been given by or on behalf of the Purchaser to the Sellers’ Representative within the period of seven (7) years commencing on the Completion Date. 6.4 Any Claim (to the extent not previously remedied, satisfied, settled or withdrawn) be deemed to have been withdrawn unless proceedings in respect of such Claim have been commenced by the Purchaser being both issued and validly served within nine (9) months after notice has first been given in accordance with Clause 6.3 and are being pursued with reasonable diligence. 6.5 Nothing in this Clause 6 applies to exclude or limit the liability of a Minority Seller to the extent that a Claim arises or is delayed as a result of fraud or wilful concealment by that Minority Seller. 6.6 If a Claim is based upon a liability that is contingent only or is not capable of being quantified, the Minority Sellers will have no liability in respect of that Claim unless and until such liability ceases to be contingent or unquantifiable and becomes an actual liability or capable of being quantified, provided that this clause will not operate to prevent the Purchaser making a Claim in respect of a contingent or unquantifiable liability if written notice of such claim is received by the Sellers’ Representative within the time limits in clause 6.3 in circumstances where the 9

EXECUTION VERSION liability does not become an actual liability or capable of being quantified until after the expiry of the relevant time limit. 6.7 Nothing in this Agreement shall restrict or limit the general obligation at law of the Purchaser to mitigate any losses which it may suffer pursuant to any Claim. 6.8 The Purchaser shall not be entitled to recover damages or obtain payment, reimbursement or restitution more than once in respect of any one liability or loss which give rise to more than one Claim. 7.

The Purchaser shall have no obligation relating to the distribution of any payment made under Clause 7.1 between any of the Minority Sellers. 7.3 Payment of any sum in accordance with Clause 7.1 will discharge the obligations of the Purchaser to pay the sum in question and the Purchaser shall not be concerned to see the application of the monies so paid. 7.4 If any sums required to be paid by a Party under this Agreement are not paid by the relevant due date, then such sums shall bear interest (which shall accrue from day to day after as well as before any judgment for the same) at the rate of four per cent per annum over the base rate from time to time of Barclays Bank Plc up to and including the day of actual payment of such sums, such interest to be payable on demand and compounded on a quarterly basis. 7.5 Each Minority Seller unconditionally and irrevocably agrees to indemnify the Purchaser, the Target and each other member of the Purchaser’s Group in respect of all Payroll Tax, to the extent permitted by law which arises as a consequence of or in connection with the disposal of the Target Shares by that Minority Seller, including, without limitation, in respect of any liability arising under or in connection with Part 7 or Part 7A of the Income Tax (Earnings and Pensions) Act 2003, together, in each case, with related interest and penalties.
