Notes:

• 1. This supplemental proxy form is the supplemental proxy form for the purpose of the supplemental resolution set out in the Supplemental Notice and only serves as a supplement to the proxy form for the 2021 First EGM to be depatched together with the notice of the 2021 First EGM dated 9 February 2021 (the "First Proxy Form"). This supplemental proxy form will not affect the validity of the First Proxy Form duly completed and lodged with the H share registrar of the Company. For the avoidance of doubt, if you have properly completed and submitted only the First Proxy Form in accordance with the instructions set out therein, your appointed proxy will vote on the resolutions set out in the First Proxy Form per your direction and he/she is also entitled to vote or abstain at his/her discretion on the resolution set out in this supplemental proxy form. Similarly, if you have properly completed and submitted only this supplemental proxy form in accordance with the instructions set out therein, your appointed proxy will vote on the resolution set out in the supplemental proxy form at your direction and he/she is also entitled to vote or abstain at his/her discretion on the resolutions set out in the First Proxy Form. If you wish to provide specific direction to your proxy regarding the voting of all resolutions set out in the First Proxy Form and this supplemental proxy form, you should duly complete and submit both the First Proxy Form and this supplemental proxy form in accordance with the instructions set out therein.

• 2. Please insert full name(s) in BLOCK CAPITALS.

• 3. Please insert full address(es) in BLOCK CAPITALS.

• 4. Please insert the number of shares registered in your name(s) to which this supplemental proxy form relates. If no number is inserted, this supplemental proxy form will be deemed to relate to all shares of the Company registered in your name(s).

• 5. If you are a shareholder who is entitled to attend and vote at the meeting, you are entitled to appoint one or more proxies to attend instead of you and to vote on your behalf. A proxy need not be a shareholder of the Company, but must attend the meeting in person in order to represent you.

• 6. If a proxy other than the Chairman of the meeting is preferred, cross out the words "the Chairman of the meeting" and insert the full name and address of the proxy (or proxies) desired in the space provided. If no name is inserted, the Chairman of the meeting will act as your proxy. Any changes made to this supplemental proxy form must be initialed by the person who signs it.

• 7. Regarding ordinary resolution number 4, a cumulative voting system will be adopted. "Cumulative voting system" refers to a system where each of the shares held by a shareholder shall carry the same number of voting rights as the number of director candidates; when the Board or a qualified shareholder separately proposes the director candidates, the number of voting rights carried by each share shall be calculated as per the number of non-repetitive director candidates. In casting his/her/its votes for the director candidates, a shareholder may exercise his/her/its voting rights by allocating his/her/its voting rights evenly and cast for each director candidate the same number of voting rights as the shares he/she/it holds; or he/she/it may focus on one particular director candidate and cast for that candidate all the voting rights represented by all of his/her/its shares multiplied by the number of director candidates; or he/she/it may allocate his/her/its voting rights over several director candidates and cast for each of them part of the voting rights represented by all of his/her/its shares multiplied by the number of director candidates.

  Upon the exercise of his/her/its voting rights by focusing all the voting rights represented by all of his/her/its shares multiplied by the number of director candidates on one or several of the director candidates, a shareholder shall not have any right to vote for any other director candidates. If the total number of voting rights centrally exercised by a shareholder on one or several of the director candidates exceeds the number of voting rights represented by all the shares held by him/her/it, the voting by such shareholder shall be invalid and the shareholder shall be deemed to have abstained from voting; if the total number of voting rights centrally exercised by a shareholder on one or several of the director candidates is less than the number of voting rights represented by all the shares held by him/her/it, the voting by such shareholder shall be valid and the remaining voting rights held by such shareholder shall be deemed to be waived.

  The director candidates whose votes represent a majority of the voting rights are elected as directors. Independent directors and other directors shall be elected separately.

• 8. IMPORTANT: IF YOU WISH TO VOTE FOR THE RESOLUTION, TICK THE APPROPRIATE BOX MARKED "FOR". IF YOU WISH TO VOTE AGAINST THE RESOLUTION, TICK THE APPROPRIATE BOX MARKED "AGAINST". IF YOU WISH TO ABSTAIN FROM VOTING, TICK THE APPROPRIATE BOX MARKED "ABSTAIN". If you return this supplemental proxy form without indicating as to how your proxy is to vote on any particular matter, the person appointed as your proxy will exercise his/her discretion as to whether he/she votes and, if so, how and, unless instructed otherwise, he/she may also vote or abstain from voting as he/she thinks fit on any other business (including amendments to resolution) which may properly come before the meeting. The shares abstained will be counted in the calculation of the required majority.

• 9. This supplemental proxy form must be signed and dated by the shareholder or his/her attorney duly authorised in writing. If the shareholder is a company, it should execute this supplemental proxy form under its common seal or by its directors or (a) person(s) duly authorised to sign on its behalf. In case of joint holders, only the person whose name stands first on the register of members may attend and vote at the EGM, either in person or by proxy.
