Notes:

• (a) A member entitled to attend and vote at the Extraordinary General Meeting is entitled to appoint one or more proxies to attend and vote instead of him. A proxy needs not be a member of the Company but must attend the Extraordinary General Meeting in person to represent you. If more than one proxy is so appointed, the appointment shall specify the number of shares of the Company in respect of which each such proxy is so appointed. Furthermore, taking into account of the epidemic caused by novel coronavirus pneumonia, in order to facilitate the prevention and control of the epidemic and to safeguard the health and safety of the members and investors, the Company suggests that the members appoint the Chairman of the Extraordinary General Meeting as a proxy to vote on the resolution, instead of attending the Extraordinary General Meeting in person.

• (b) To be valid, a form of proxy and the power of attorney or other authority (if any) under which it is signed or a notarially certified copy of that power or authority, must be deposited at the Company’s branch share registrar in Hong Kong, Computershare Hong Kong Investor Services Limited, 17M Floor, Hopewell Centre, 183 Queen’s Road East, Wanchai, Hong Kong not less than 48 hours before the time appointed for holding the meeting or the adjourned meeting (as the case may be).

• (c) Completion and delivery of the form of proxy will not preclude a member from attending and voting in person at the Extraordinary General Meeting if the member so desires and in such event, the instrument appointing a proxy shall be deemed to be revoked.

• (d) Where there are joint holders of any share of the Company, any one of such holders may vote at the Extraordinary General Meeting, either personally or by proxy, in respect of such share as if he or she were solely entitled thereto, but if more than one of such holders be present at the Extraordinary General Meeting personally or by proxy, that one of such holders so present whose name stands first on the register of members of the Company in respect of such share shall alone be entitled to vote in respect thereof.
