You are entitled to appoint a proxy or proxies, who need not be a member of the Company or the chairman, to exercise all or any of your rights to attend, speak and vote at a general meeting of the Company (although please see the chairman's letter enclosed in the Notice to the Annual General Meeting as to the recommendation to appoint the chairman as your proxy). If you wish to appoint a person other than the chairman, please insert the name of your chosen proxy holder in the space provided. If no name is inserted in the space provided, the chairman of the meeting will be deemed to be your proxy. You must follow the appointment procedures set out in these notes.
• 1. You may appoint more than one proxy provided each proxy is appointed to exercise rights attached to a different share or shares. Please indicate by ticking the box provided if the instruction is one of multiple instructions being given. If the proxy is being appointed in relation to less than your full voting entitlement, please enter in the box next to the proxy holder's name the number of shares in relation to which they are authorised to act as your proxy. If left blank your proxy will be deemed to be authorised in respect of your full voting entitlement.

Unless instructed otherwise, the proxy may also vote or abstain from voting as he thinks fit on any other business which may properly come before the Meeting.
