             no liability to corporation tax on chargeable gains or balancing
             charge under CAA would arise; and, for the purpose of determining
             the liability to corporation tax on chargeable gains, there shall
             be disregarded any relief and allowances available to the Group

16.4         In determining the liability to corporation tax on chargeable
             gains in respect of any assets which has been acquired or provided

             accordance with the provisions of TCGA s 38 (Acquisition and
             disposal costs, etc);

16.4.2       the amount or value of the consideration, determined pursuant to
             TCGA s 38(l) (a) will not be less than the amount or value of the
             consideration actually given by the Group Company for that asset;

16.4.3       the amount of any expenditure on enhancing the value of that
             asset, determined pursuant to TCGA, s 38(l)(b), will not be less

             corporation tax on chargeable gains will arise by reason of the
             provisions of TCGA s 251 (Debts).

17.2         No Group Company has claimed or is entitled to claim under TCGA s
             253 or 254 (Relief in respect of loans to traders) that an

             holding of shares (within the meaning of TCGA s 126 (Application
             of ss 78 to 81)) will be disregarded by virtue of the proviso to
             TCGA s 128(2).

17.5         No asset owned by a Group Company has been the subject of a deemed
             disposal under TCGA Sched 2 (Assets held on 6 April 1965) so as to
             restrict the extent to which the gain or loss, over the period of
             ownership, may be apportioned by reference to straightline growth.

             reduction in liability to, Taxation; and, without prejudice to the
             generality of the foregoing, no Group Company has been a party to,
             or otherwise involved in, any transaction to which any of the

             force and effect, and so far as the Vendors are aware nothing has
