* The 'Number of Shares Acquired' includes 67 Partnership shares acquired at 187

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.
