Notes:

1. 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 offi cer, attorney or other person authorised to sign the same. In the case of an instrument of proxy purporting to be signed on behalf of a corporation by an offi cer thereof it shall be assumed, unless the contrary appears, that such offi cer was duly authorised to sign such instrument of proxy on behalf of the corporation without further evidence of the fact.

2. A member entitled to attend and vote at the EGM is entitled to appoint one or more proxies to attend and vote instead of him. A proxy need not be a member of the Company but must attend the meeting in person to represent you.

3. 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 certifi ed 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).

4. Delivery of the form of proxy will not preclude a member from attending and voting in person at the meeting or any adjourned meeting thereof (as the case may be) should they so wish and in such event, the form of proxy shall be deemed to be revoked.

5. Where there are joint holders of any share(s), any one of such joint holders may vote at the meeting, either in person or by proxy, in respect of such share(s) as if he were solely entitled thereto, but if more than one of such joint holders be present at the meeting, the vote of the senior who tenders a vote, whether in person or by proxy, will be accepted to the exclusion of the votes of the other joint holders. For this purpose, seniority shall be determined by the order in which the names stand in the register of members of the Company in respect of the joint holding.

6. The votes of members at the above meeting to approve the ordinary resolution will be taken on a poll.

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