If more than one proxy is so appointed, the appointment shall specify the number and class of shares in respect of which each such proxy is so appointed.

2. In order to be valid, the form of proxy together with any power of attorney or other authority under which it is signed, or a certified copy of such power of attorney or authority, must be deposited with the Company’s branch share registrar and transfer office in Hong Kong, Tricor Investor Services Limited, at 17/F, Far East Finance Centre, 16 Harcourt Road, Hong Kong not less than 48 hours before the time appointed for the Meeting (i.e. not later than 11:15 a.m. on Tuesday, 26 May 2026) or the adjourned meeting (as the case may be).
