Proxy Form for the Solicitation of Voting Rights by Independent Non-Executive Directors (“Independent Director’s Proxy Form”)

Pursuant to the Management Measures for Share Incentives of Listed Companies (《上市 公司股權激勵管理辦法》) (“ Management Measures ”), the independent non-executive directors of a listed company shall solicit voting rights from all shareholders of the company in the event of the proposed adoption of a share option scheme by such company. Hence, you shall appoint Ms. Li Lihua as your proxy to vote for you and on your behalf on the resolutions regarding the 2023 A Share Incentive Scheme and the related matters, which include the proposed adoption of 2023 A Share Incentive Scheme, the proposed adoption of the Assessment Management Measures for the implementation of the 2023 A Share Incentive Scheme and the proposed authorization to the Board to handle matters pertaining to the 2023 A Share Incentive Scheme at the 2022 AGM. In accordance with the latest Management Measures, you shall also appoint Ms. Li Lihua as your proxy to vote for you and on your behalf on other resolutions at the 2022 AGM. The solicitation is intended to provide shareholders of such listed company with an alternative approach to participation in general meetings, so as to encourage them to vote on the resolution in respect of the adoption of a share option scheme. Pursuant to the Management Measures and the authorization of other independent non-executive Directors, Ms. Li Lihua, an independent non-executive Director, has sent out an Independent Director’s Proxy Form to solicit voting rights from the Shareholders.

Should you wish to appoint Ms. Li Lihua as your proxy to vote for you and on your behalf on the resolutions regarding (i) the 2023 A Share Incentive Scheme and the related matters and, as you may think fit, (ii) other resolutions at the 2022 AGM, please complete and return the Independent Director’s Proxy Form to Tricor Investor Services Limited, the H share registrar of the Company, at 17/F, Far East Finance Centre, 16 Harcourt Road, Hong Kong, by hand or by post, no later than 24 hours before the time appointed for holding the 2022 AGM or any adjournment thereof.

In addition, if you wish to appoint persons other than Ms. Li Lihua as your proxy to vote for you and on your behalf on all resolutions at the 2022 AGM, you may complete and return the form of proxy only and disregard the Independent Director’s Proxy Form.

Please note that if you have completed and returned both the form of proxy and the Independent Director’s Proxy Form, but have given inconsistent voting instructions on the resolutions concerned between the form of proxy and the Independent Director’s Proxy Form, your voting instructions given in the last form of proxy duly signed by you will be counted as your vote for or against the resolutions or abstain from voting on the resolutions concerned. If the signing time of such form of proxy cannot be ascertained, the last form of proxy duly received shall prevail. You cannot vote multiple times on the same resolution. In the event of multiple votes being cast on the same resolution (through on-site voting, proxy voting, and/ or online voting), the vote that was cast in the first instance will be counted as your vote for or against the resolutions or abstain from voting on the resolutions concerned.
