Whether or not you are able to attend the EGM, you should complete and return the enclosed Revised Proxy Form in accordance with the instructions printed thereon to Hong Kong Registrars Limited at 17M Floor, Hopewell Centre, 183 Queen’s Road East, Wanchai, Hong Kong as soon as practicable and in any event not less than 24 hours before the time for holding the EGM or any adjournment thereof (as the case may be).

Special arrangements about completion and submission of the Revised Proxy Form are set out in the supplemental notice of EGM. Shareholders who have appointed or intended to appoint proxy(ies) to attend the EGM are requested to pay particular attention to the special arrangements set out therein.

Completion and return of the Initial Proxy Form and/or the Revised Proxy Form will not preclude you from attending and voting in person at the EGM or any adjournment thereof (as the case may be).

Pursuant to Rule 13.39(4) of the Hong Kong Listing Rules, all votes at the EGM will be taken by poll and the Company will announce the results of the poll in the manner prescribed under Rule 13.39(5) of the Hong Kong Listing Rules.
