Please indicate in the box beneath the proxy's name, the number of shares in respect of which the relevant proxy is authorised to act on your behalf. If the box beneath the proxy's name is left blank, your proxy will be deemed to be authorised in respect of all shares (or, if this proxy form has been issued in respect of a designated account for a shareholder, the full voting entitlement for that designated account). Please tick the box provided to indicate if you are appointing multiple proxies. All forms must be signed and should be returned together in one envelope to the address on the back of this proxy form (reply paid in the UK).
