| | ------ | ---------------------------------------------------------------------------------------------------------------



|25. | TAX AND OTHER COSTS AND EXPENSES
|--- | --------------------------------



|25.1 | Upon the receipt of any amount under the Tax Deed of Covenant (as defined in the Credit Agreement), the Seller shall forthwith subscribe that amount for Deferred Shares (as defined

completion) of the Option, paid stamp duty in respect of this Agreement or has accounted for stamp duty reserve tax in respect of the grant of the Option, the Seller will within 10 Business Days reimburse to the Buyer the amount of such stamp duty
or (as the case may be) stamp duty reserve tax. If the Seller so requests, the Buyer will use all reasonable endeavours to assist the Seller to minimise the stamp duty or stamp duty reserve tax due on the grant of the Option. For the avoidance of

minimise the stamp duty or stamp duty land tax due on exercise of the Option.
| | ------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



|25.3 | The Seller and the Buyer shall make all reasonable efforts to ensure the Company ceases from the Option Completion Date, to be treated by HM Customs & Excise as a member of a
group with a Sellers Group Company for the purposes of section 43 to 43C (inclusive) of the Value Added Tax Act 1994 and/or paragraph 6 of SI 2001/7 (Climate Change Levy). Where the Company is in a group for the purposes of Value Added Tax
(VAT) or Climate Change Levy (CCL) (or any substantially similar tax group) with a Sellers Group Company after the Option Completion Date, such payments shall be made by the Company to, or to the Company
by, the representative member of the VAT, CCL or other group to ensure that (ignoring in the case of VAT, supplies between members of that VAT group) the representative member and the Company are put in the position they would have been had the
relevant group not been in existence from the Option Completion Date. The Seller and the Buyer shall take such steps as are reasonably within their powers for so long as may be reasonably necessary to give each other all the assistance and
co-operation as may be required to enable the representative member of any such VAT or CCL or other group to comply with its obligations as representative member of the relevant group. The Seller shall pay to the Buyer an amount equal to any
liability of the Company for VAT and/or CCL debts incurred by the Company in consequence of the joint and several liability of members of VAT or CCL groups where the liability is one the Company would not have incurred had no VAT or CCL group (as
the case may be) been in existence between the Company and a Sellers Group Company.

|25.4 | The Buyer agrees with the Seller that if Completion takes place, the Buyer will procure that the Company does nothing after Break Option Completion or Enforcement Option Completion
(as the case may be) that will give rise to a liability under section 767A or section 767AA Income and Corporation Taxes Act 1988 (or similar legislation enacted after the date hereof but before Completion takes place) for a Sellers Group
Company (or any person which is then or has been in control of a Sellers Group Company, or is then or has been under the control of a Sellers Group Company) in respect of or referable to Tax relating to income, profits or gains of the
Company arising after Completion except to the extent:
|---- | ----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| | 25.4.1 | such income, profits or gains have in accordance with generally applicable accounting standards been treated in the Companys accounts as arising prior to Completion; or

Company (including the Company) and some undertaken by the Buyer or the Company after, Completion provided that this exception shall not apply to any actions taken by the Buyer or, after Completion, the Company outside the ordinary course of
trading.
