NOTES:
1. A signatory to this form of proxy may insert the name of a proxy or the name of an alternative proxy of the signatory’s
choice in the blank spaces provided with or without deleting “the chairman of the General Meeting”, but any such
deletion must be signed in full by the signatory. Any insertion or deletion not complying with the foregoing will
be deemed not to have been validly effected. The person present at the General Meeting whose name appears first
on the list of names overleaf, shall be the validly appointed proxy for the shareholder at the General Meeting.
2.

votes in the same way, but the total of votes cast, and in respect whereof abstention is directed, may not exceed the
total of the votes exercisable by the shareholder or the proxy. Failure to comply with the above or to provide voting
instructions or the giving of contradictory instructions will be deemed to authorise the proxy, if he is the Chairman
of the General Meeting, to vote in favour of all resolutions at the General Meeting in respect of all the shareholder’s
votes exercisable at the General Meeting or if he or she is not the Chairman of the General Meeting, to vote or abstain
from voting at the General Meeting as he/she deems fit in respect of all the shareholder’s votes exercisable at the
General Meeting.

shall have been received by the share registrars not less than twenty-four hours before the commencement of the
General Meeting, or at any adjournment thereof.
