This supplemental proxy form will not affect the validity of any Original Proxy Form duly completed and lodged with the H Share Registrar. For the avoidance of doubt, if a Shareholder has properly completed and submitted only the Original Proxy Form in accordance with the instructions set out therein, the appointed proxy will vote on the resolutions set out in the Original Proxy Form per the Shareholder's instruction and he is also entitled to vote or abstain at his discretion on the additional resolutions set out in this supplemental proxy form. Similarly, if a Shareholder has properly completed and submitted only this supplemental proxy form in accordance with the instructions set out therein, the appointed proxy will vote on the resolutions set out in this supplemental proxy form per the Shareholder's instruction and he is also entitled to vote or abstain at his discretion on the resolutions set out in the Original Proxy Form. If a Shareholder wishes to provide specific direction to his proxy regarding the voting of all resolutions set out in the Original Proxy Form and the supplemental proxy form, he should duly complete and submit both the Original Proxy Form and the supplemental proxy form in accordance with the instructions set out therein.

Your proxy will also be entitled to vote or abstain at his discretion in respect of any resolution properly put to the meeting other than those referred to in the notice and supplemental notice of the meeting. The "ABSTAIN" votes will be counted in the calculation of the required majority.
