Notes:

1. Any shareholder entitled to attend and vote at the Special Meeting is entitled to appoint another person as his/her/its proxy to attend and vote instead of his/her/it. A shareholder who is the holder of two or more Shares may appoint more than one proxy to attend on the same occasion. A proxy need not be a Shareholder of the Company but must be present in person at the Meeting to represent the Shareholder. Completion and return of the form of Proxy will not preclude a Shareholder from attending the Meeting and voting in person. In such event, his/her/its form of Proxy will be deemed to have been revoked.

2. The proxy must be dated and must be executed by the Shareholder or his attorney authorized in writing or, if the Shareholder is a body corporate, under its corporate seal or by an officer or attorney thereof duly authorized. A copy of such authorization should accompany the proxy. Persons signing as executors, administrators, trustees, etc. should so indicate. If this Proxy is not dated, it shall be deemed to bear the date on which it was mailed to the Shareholder by the Company.

3. Where there are joint holders of any Share, any one of such joint holders may appoint the chair of the Special Meeting to vote, in respect of such Share as if he/she/it was solely entitled thereto.

As at the date of this notice, the Board consists of Mr. Kwok Ping Sun and Ms. Gloria Pui Yun Ho as executive directors; Mr. Michael John Hibberd and Ms. Xijuan Jiang as non-executive directors; and Mr. Yi He, Mr. Guangzhong Xing and Ms. Jue Pang as independent non-executive directors.
