• (3) The Company will keep the evolving COVID-19 situation under review and may implement additional measures which it will announce closer to the date of the SGM (if any).

• (4) Any member entitled to attend and vote at a meeting of the Company shall be entitled to appoint another person as his proxy to attend and vote instead of him.

• (5) The instrument appointing a proxy shall be in writing under the hand of the appointor or of his attorney duly authorised in writing or, if the appointor is a corporation, either under its seal or under the hand of an officer, attorney or other person authorised to sign the same.

In addition, a proxy or proxies representing either a member who is an individual, or a member which is a corporation shall be entitled to exercise the same powers on behalf of the member which he or they represent as such member could exercise.

• (9) Completion and return of a form of proxy will not preclude a member from attending in person and voting at the above meeting or any adjournment thereof, should he so wish.

• (10) Pursuant to Rule 13.39(4) of the Listing Rules, any vote of the shareholders at a general meeting must be taken by poll. Therefore, the Chairman of the meeting will demand that all resolutions will be voted by way of poll at the meeting.
