2. Any member of the Company entitled to attend and vote at a meeting of the Company shall be entitled to appoint another person as his/her proxy to attend and vote instead of him/her. A member who is the holder of two or more shares of the Company may appoint more than one proxy to represent him/her and vote on his/her behalf. A proxy need not be a member of the Company. 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/she/they represent as such member could exercise.

3. The instrument appointing a proxy shall be in writing under the hand of the appointor or of his/her 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.

4. The instrument appointing a proxy (if required by the Board) together with the power of attorney or other authority (if any) under which it is signed, or a certified copy of such power of authority, must be delivered to the offices of the Company's branch share registrar, Computershare Hong Kong Investor Services Limited (the "Branch Share Registrar") at 17M Floor, Hopewell Centre, 183 Queen's Road East, Wanchai, Hong Kong not less than forty-eight (48) hours before the time appointed for holding the meeting or adjourned meeting at which the person named in the instrument proposes to vote (the "Closing Time") and in default the instrument of proxy shall not be treated as valid.

5. Delivery of an instrument appointing a proxy shall not preclude a member of the Company from attending and voting in person at the meeting convened and in such event, the instrument appointing a proxy shall be deemed to be revoked.

6. A revised form of proxy (the "Revised Proxy Form") is enclosed with this supplemental notice. A Shareholder who has not yet lodged the proxy form enclosed with the circular of the Company dated 29 April 2026 in respect of the AGM (the "Original Proxy Form") with the Branch Share Registrar is requested to lodge the Revised Proxy Form if he/she wishes to appoint proxy(ies) to attend and vote at the AGM on his/her behalf. In this case, the Original Proxy Form should not be lodged with the Branch Share Registrar.

7. A Shareholder who has already lodged the Original Proxy Form with the Branch Share Registrar should take note of the following:

(i) subject to (iii) below, if no Revised Proxy Form is lodged with the Branch Share Registrar, the Original Proxy Form will be treated as a valid form of proxy lodged by him/her if correctly completed and signed. The proxy so appointed by the Shareholder shall be required to vote in such manner as he/she may be directed under the Original Proxy Form and, in respect of the resolution for the proposed re-election of Ms. Huang as an independent non-executive Director as set out in the Supplemental AGM Notice and the Revised Proxy Form, the proxy will be entitled to vote at his/her discretion or to abstain from voting on such resolutions;

(ii) if the Revised Proxy Form is lodged with the Branch Share Registrar before the Closing Time, the Revised Proxy Form, if correctly completed and signed, shall revoke and supersede the Original Proxy Form previously lodged by him/her. The Revised Proxy Form will be treated as a valid form of proxy lodged by the Shareholder; and

(iii) if the Revised Proxy Form is lodged with the Branch Share Registrar after the Closing Time, or if lodged before the Closing Time but is incorrectly completed, the proxy appointment under the Revised Proxy Form will be invalid. The proxy so appointed by the Shareholder under the Original Proxy Form, if correctly completed, will be entitled to vote in the manner as mentioned in (i) above as if no Revised Proxy Form was lodged with the Branch Share Registrar.
