Notes:

1. A member entitled to attend and vote at the EGM (or at any adjournment thereof) is entitled to appoint one or (if he holds two or more shares) more proxies to attend and vote in his stead. A proxy need not be a member of the Company.

2. The instrument appointing a proxy shall be in writing under the hand of the appointer or of his/her attorney duly authorised in writing, or if the appointer is a corporation, either under its seal or under the hand of an officer, attorney or other person duly authorised to sign the same.

3. Where there are joint registered holders of any shares, any one of such persons may vote at the EGM (or at any adjournment thereof), either personally or by proxy, in respect of such shares as if he were solely entitled thereto; but if more than one of such joint holders be present at the EGM personally or by proxy, that one of the said persons 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.

4. In order to be valid, the form of proxy, together with the power of attorney or other authority (if any) under which it is signed or a notarially certified copy of that power of attorney or authority (such certification to be made by either a notary public or a solicitor qualified to practise in Hong Kong), must be deposited with the branch share registrar and transfer office of the Company in Hong Kong, Tricor Investor Services Limited, Level 54, Hopewell Centre, 183 Queen’s Road East, Hong Kong, not less than 48 hours before the time fixed for holding the EGM (i.e. not later than 3:00 p.m. on Monday, 8 February 2021) or any adjournment thereof.

5. For determining the entitlement to attend and vote at the EGM, the register of members of the Company will be closed from Friday, 5 February 2021 to Wednesday, 10 February 2021, both dates inclusive, during which period no transfer of shares will be registered. In order to be eligible to attend and vote at the EGM, unregistered holders of shares shall ensure that all transfer documents accompanied by the relevant share certificates must be lodged with the Company’s branch share registrar and transfer office in Hong Kong, Tricor Investor Services Limited, at Level 54, Hopewell Centre, 183 Queen’s Road East, Hong Kong for registration not later than 4:30 p.m. on Thursday, 4 February 2021.

6. Completion and return of the form of proxy will not preclude a member from attending and voting in person at the EGM or any adjourned meeting (as the case may be) should he so wish and in such event, the proxy form previously served will be deemed to be revoked.

7. In compliance with the GEM Listing Rules, the resolution to be proposed at the EGM will be voted by way of poll.

8. The translation into Chinese language of this notice is for reference only. In case of any inconsistency, the English version shall prevail.
