Persons Discharging Managerial Responsibility
Grant Dawson                                          62       316,258
Anne Minto                                            62        43,370

* The 'Number of Shares Acquired' includes 42 Partnership shares (except for
Chris Weston which includes 31 Partnership shares) acquired at 293.00 pence and
20 Matching shares (except for Chris Weston which includes 15 Matching shares)
acquired at 282.33 pence. Both Partnership and Matching elements are registered
in the name of the Trustee.

(2) They had transferred 10,080 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 February's allocation of Matching shares. The
Directors listed above, together with some 5,222 other employees, are potential
participants in the Plan and are to be treated as interested in the remaining
863 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.
