Notes:

1. Any shareholder of the Company entitled to attend and vote at the meeting is entitled to appoint another person as his proxy to attend and vote instead of him. Any shareholder of the Company who is the holder of two or more shares may appoint more than one proxy to represent him and vote on his behalf at the meeting. A proxy need not be a shareholder of the Company.

2. Where there are joint holders of any share, any one of such joint holder may vote, either in person or by proxy, in respect of such share 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, shall be accepted to the exclusion of the votes of the other joint holders, and 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.

3. The instrument appointing a proxy shall be in writing under the hand of the appointer or of his attorney duly authorised in writing or, if the appointer is a corporation, either under its seal or under the hand of an officer, 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 officer thereof it shall be assumed, unless the contrary appears, that such officer was duly authorised to sign such instrument of proxy on behalf of the corporation without further evidence of the fact.

4. To be valid, the form of proxy, together with a power of attorney or other authority, if any, under which it is signed or a notarially certified copy thereof, must be lodged with the Company's Hong Kong share registrar, Tricor Investor Services Limited, at Level 22, Hopewell Centre, 183 Queen's Road East, Hong Kong not less than forty-eight (48) hours before the time appointed for holding the meeting or any adjournment thereof. Completion and return of the form of proxy will not preclude a member from attending and voting in person at the meeting.

5. The register of members of the Company will not be closed for the purpose of ascertaining the right of shareholders of the Company to attend and vote at the Extraordinary General Meeting. However, in order to qualify for attending and voting at the Extraordinary General Meeting, all transfers, accompanied by the relevant share certificates, must be lodged for registration with the Company's share registrar in Hong Kong, Tricor Investor Services Limited, at Level 22, Hopewell Centre, 183 Queen's Road East, Hong Kong not later than 4 : 30 p.m. on 11 July 2016.
