* The 'Number of Shares Acquired' includes 42 Partnership shares (41 Partnership
shares for Sam Laidlaw with a lower residual balance) acquired at 303.00 pence
per share and 20 Matching shares acquired at 303.92 pence per share. Both
Partnership and Matching elements are registered in the name of the Trustee.

(2) They had transferred 11,000 ordinary shares of 6 14/81 pence each from
Lloyds TSB Registrars Corporate Nominee Limited AESOP1 (Allocated shares) to
Lloyds TSB Registrars Corporate Nominee 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 March's allocation of Matching shares. The
Directors and PDMRs listed above, together with some 5,182 other employees, are
participants in the SIP and are potentially interested in the remaining 833
shares held by Lloyds TSB Registrars 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.
