* The 'Number of Shares Acquired' includes 39 Partnership shares acquired at
321.00 pence per share and 19 Matching shares acquired at 325.67 pence per
share. Both Partnership and Matching elements are registered in the name of the
Trustee.

(2) They had transferred 10,000 ordinary shares of 6 14/81 pence each from
Equiniti Corporate Nominees Limited AESOP1 (Allocated shares) to Equiniti
Corporate Nominees Limited AESOP2 (Unallocated shares). The transfer was made
following the forfeiture of shares, under the rules of the SIP, by participants
who have left the group since the last purchase and the shares had been used
towards September's allocation of Matching shares. The Directors and PDMRs
listed above, together with some 5,055 other employees, are participants in the
SIP and are potentially interested in the remaining 2,890 shares held by
Equiniti Corporate Nominee Limited AESOP2 left following the purchase.

The SIP operates as follows

    --  Each month the Trustee uses participants' contributions (which may not
        exceed £125 per participant per month) to purchase shares in the market.
        These shares are called 'Partnership Shares'.

    --  At the same time the Company allots to participants via the Trustee one
        'Matching Share' for every two partnership shares purchased that month
        (up to a maximum of 20 matching shares per month).

    --  Participants may change their monthly savings rate whenever they wish.
        However, Directors and others bound by the Company's Securities Dealing
        Code (the 'Code') may not make such a change during a close period or
        when otherwise prohibited from dealing by the Code.
