                  the Group claims under or in respect of this Tax Indemnity but

                  first made a demand under this Tax Indemnity and the relevant
                  Warrantor has neglected or defaulted under such demand, and in
                  which judgment is given for the Purchaser or any company of
                  the Group; or

             (iii) the enforcement of any such settlement or judgment.

2.02    This Tax Indemnity does not cover any Claim and the Warrantors shall be
        under no liability under this indemnity in respect of Taxation:-

        (a)  to the extent that provision has been made for such Taxation in the
             Accounts; or

             than in the ordinary course of business after the date hereof; or

             operations since 31 December 2004; or

        (d)  to the extent that such Claim arises or is incurred as a result of

             change in the law or Inland Revenue practice coming into force
             after the date hereof or to the extent such Claim arises or is
             increased by an increase in rates of Taxation after the date hereof
             with retrospective effect.

        Purchaser, the Company and the Subsidiaries in respect of the same

     reasonably practicable, to the Warrantors and, as regards any Claim, the
     Company or the relevant Subsidiary and/or the Purchaser shall take such
     action to cause the Claim to be withdrawn, or to dispute, resist, appeal
     against, compromise or defend the Claim and any determination in respect

     by the Warrantors from and against any and all losses, liabilities
     (including additional Taxation), damages, interest, penalties, costs,
     charges and expenses which may be thereby sustained or incurred.

     Claim nor agree any matter in the course of disputing any Claim likely to
