Validity of proxies
86 (A) Unless the contrary is stated therein, the appointment of a proxy shall be valid for any adjournment of the meeting or meetings to which it relates, and for any poll arising from any such meeting or adjourned meeting.
(B) The valid appointment of a proxy relating to more than one meeting (including any adjournment thereof), having once been so delivered for the purposes of any meeting, shall not have to be re-lodged or otherwise re-registered with the Company for the purposes of any subsequent meeting to which it relates.
(C) A validly appointed proxy shall have the right to demand or join in demanding a poll and the right to speak at a meeting.
(D) Notice of the revocation of the appointment of a proxy may be given in any lawful manner which complies with all (if any) regulations for the time being in force that the Directors have made to govern how a proxy is validly revoked. Nevertheless, a vote cast by proxy shall not be invalidated by the previous death or insanity of any appointor, or by the revocation of the appointment of the proxy or of the authority under which the appointment was made, unless notice (in writing or by electronic communication) of such death, insanity or revocation shall have been received by the Company at such place or one of such places (if any) as may be specified for the purpose in any notice convening the meeting or in any material accompanying the notice convening the meeting (or, if no place is so specified, at the Transfer Office) at least forty-eight hours (or such shorter time as the Directors may determine) before the time appointed for the commencement of the meeting or adjourned meeting (or, in the case of a poll taken otherwise than at or on the same day as the meeting or adjourned meeting, before the time appointed for the taking of the poll) at which the vote is cast. Calculation of any such forty-eight hour period shall take no account of any part of a day that is not a working day.
