3. Please insert the name and address of the proxy. If no name is inserted, the chairman of the meeting will act as the proxy. A shareholder of the Company (the “Shareholder(s)”) may appoint one or more proxies to attend the EGM and vote for him/her provided that each proxy is appointed to exercise the rights attached to different share or shares held by the Shareholder. To appoint more than one proxy, a photocopy of this proxy form may be used. The proxy needs not be a Shareholder, but must attend the EGM (or any adjournment thereof) in person to represent you.

IF YOU WISH TO VOTE AGAINST A RESOLUTION, TICK (✓) IN THE RELEVANT BOX BELOW THE BOX MARKED “AGAINST”. IF YOU WISH TO USE LESS THAN ALL YOUR VOTES, OR TO CAST SOME OF YOUR VOTES “FOR” AND SOME OF YOUR VOTES “AGAINST” A PARTICULAR RESOLUTION, YOU MUST WRITE THE NUMBER OF VOTES IN THE RELEVANT BOX(ES). Failure to tick either box or write the number of votes in the box in respect of a resolution will entitle your proxy to cast your vote in respect of that resolution at his/her discretion or to abstain from voting. Your proxy will also be entitled to vote at his/her discretion or to abstain from voting on any resolution properly put to the EGM other than those referred to in the notice convening the EGM.
5. This proxy form must be signed by you or your agent duly authorised in writing or, in the case of a corporation, must either be executed under its common seal or be signed by an officer or agent duly authorised in writing. ANY ALTERATION MADE TO THIS PROXY FORM MUST BE INITIALLED BY THE PERSON WHO SIGNS IT.
6. In order to be valid, this completed proxy form, together with the power of attorney or other authority (if any) under which it is signed or a 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 lodged with the Company's branch share registrar and transfer office in Hong Kong (the “Share Registrar”), Computershare Hong Kong Investor Services Limited at 17M Floor, Hopewell Centre, 183 Queen’s Road East, Wanchai, Hong Kong not less than 48 hours before the time for holding the EGM or its adjournment (as the case may be).
7. Submission of this proxy form shall not preclude you from attending the EGM or its adjournment and voting in person should you so wish, but the appointment of the proxy will be revoked if you attend in person at the EGM.
8. If you have returned a proxy form, you may revoke it by completing and signing a proxy form bearing a later date, and lodging it with the Share Registrar. In order to be valid for voting purposes, this latter proxy form should be received by Share Registrar not later than 48 hours before the time appointed for holding the EGM or its adjournment (as the case may be) (the “Closing Time”). If this latter proxy form is lodged with Share Registrar after the Closing Time, it will be invalid for voting purpose. However, it will revoke any previous proxy form and any vote that may be cast by the purported proxy will not be counted in any poll taken on a proposed resolution.
9. In the case of joint registered holders of any shares, any one of such persons may vote at the EGM, either personally or by proxy, in respect of such shares as if he/she were solely entitled thereto but if more than one of such joint holders are present at the EGM personally or by proxy, the vote of the senior holder who tenders a vote, whether in person or by proxy, will be accepted to the exclusion of the vote(s) of the other joint holders and, for this purpose, seniority shall be determined by the order in which the names stand in the Company's register of members in respect of the relevant joint holding.
10. The Company reserves the right to treat any proxy form which has been incorrectly completed in some manner which (at its absolute discretion) is not material as being valid.
