NOTES FOR COMPLETION OF FORM OF PROXY

APPOINTING A PROXY

1. A proxy need not be a member of the Company but must attend the AGM to represent you. If you are unable to join us in person or prefer to follow the business of the AGM via a live webcast, shareholders are encouraged to appoint the Chair of the Meeting as their proxy (by leaving the box overleaf blank).
2. Please indicate by placing 'X' under the column 'For' or the column 'Against' or the column 'Withheld' how you wish your votes to be cast. On receipt of this form duly signed, but without any specific direction how you wish your vote to be cast, your proxy may vote or abstain, at their discretion. On any other business (including a motion to adjourn the Meeting or to amend a resolution) the proxy will vote at their discretion.
3. The 'Withheld' option is provided to enable you to abstain on the resolution. However, it should be noted that a 'Withheld' vote is not a vote in law and will not be counted in the calculation of the proportion of the votes 'For' or 'Against' the resolution.
4. In the case of joint shareholders, the vote of the first named in the Register of the Company who tenders a vote whether in person or by proxy shall be accepted to the exclusion of the votes of the other shareholder(s).
5. In the case of a shareholder which is a body corporate, this form must
   be executed either under its common seal, or under the hand of an officer or agent duly authorised in writing on its behalf.
