The BOC Group plc (the Company) has today been notified of the disposal on 20

price of 882.5p per share by Ogier Trustee Limited (the Trustee) as trustee of

Company's senior executive share option plans.


Following this disposal of 6,973 Ordinary shares, the Trustee now holds

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.
