Notes:

1. A proxy need not be a shareholder of the Company. A shareholder is entitled to appoint a proxy of his/her own choice to attend and vote instead of him/her. If such an appointment is made, delete the words "or failing him/her the duly appointed Chairman of the Annual General Meeting" and insert the name and address of the person appointed as proxy in the space provided. If no name is inserted, the Chairman of the Annual General Meeting will act as your proxy.

2. Please indicate with a “/” in the appropriate space beside each of the resolutions how you wish the proxy to vote on your behalf. If this form is returned duly signed but without any indication, the proxy will vote for or against the resolutions or will abstain at his discretion at the meeting.

3. In the case of joint holders of a share in the Company, 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 is determined by the order in which the names stand in the register of members in respect of the joint holding.

4. If the appointor is a corporation, this form must be executed under its common seal or under the hand of an officer or attorney duly authorised to sign the same.

5. To be valid, this proxy form together with the power of attorney or other authority (if any) under which it is signed, or a notarially certified copy of such power or authority, must be lodged with the Company's share registrar, 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 holding the Annual General Meeting or adjourned meeting (as the case may be) or, in the case of a poll taken subsequently to the date of the meeting or adjourned meeting, not less than 24 hours before the time appointed for the taking of the poll. In the event that you attend the meeting after having lodged this proxy form, this proxy form will be deemed to have been revoked.
