Following this disposal of 30,000 Ordinary shares, the Trustee now holds
5,334,815 Ordinary shares.

Each of the executive Directors of the Company is a potential beneficiary under
the Trust and therefore for Companies Act purposes is regarded as interested in
all of these 5,334,815 Ordinary shares. Despite this technical interest, each
executive Director will only be entitled to receive Ordinary shares from the
Trust in satisfaction of options granted to him in respect of these Ordinary
shares.
