Notwithstanding the foregoing, the Chair of the Meeting has the discretion to accept proxies received after such deadline. The time limit for deposit of proxies may be waived or extended by the Chair of the Meeting at his discretion, without notice. Proxies may also be deposited with the Chair of the Meeting prior to the commencement of the Meeting.
