(Stock Code: 388)

17 March 2021

Dear Shareholder

Hong Kong Exchanges and Clearing Limited ("HKEX")

Letter to New Registered Shareholders − Election of Language and Means of Receipt of Corporate Communications

We are pleased to enclose HKEX's 2020 Annual Report (in both English and Chinese), and Circular dated

17 March 2021 containing the notice of the annual general meeting together with the relevant proxy form for your attention.

Pursuant to the Rules Governing the Listing of Securities on The Stock Exchange of Hong Kong Limited and HKEX's Articles of Association, HKEX is permitted to supply Corporate Communications (Note) to Shareholders either (i) in printed form, in English and/or Chinese ("Printed Version") or (ii) by electronic means through the HKEX Group website(www.hkexgroup.com)and HKEXnews website(www.hkexnews.hk) ("Electronic Version").

We write to ascertain your preference in receiving all future Corporate Communications. To make your election, please complete, sign and return the enclosed reply form by post (using the mailing label at the bottom of the reply form) to HKEX's registrar, Hong Kong Registrars Limited.

If HKEX does not receive the duly completed and signed reply form or any response from you indicating your objection to access Corporate Communications by electronic means through the HKEX Group website by 14 April 2021, you are deemed to have elected the Electronic Version instead of the Printed Version.

If you have elected (or are deemed to have elected) the Electronic Version, HKEX will, on the same day when the Printed Version is mailed, notify you of the publication of such Corporate Communication on the HKEX Group website by email or, if no email address is provided, by post to your address as it appears in HKEX's register of members.

Please note that the English and Chinese versions of all Corporate Communications are available on the HKEX Group website and the HKEXnews website, and their printed copies are available from HKEX's registrar on request.

You may at any time change your choice of language or means of receipt of all future Corporate Communications by giving not less than seven days' notice in writing to Hong Kong Registrars Limited (by post to 17M Floor, Hopewell Centre, 183 Queen's Road East, Wan Chai, Hong Kong or by email [e-mail]). Even if you have elected (or are deemed to have elected) the Electronic Version but for any reason have difficulty in accessing the relevant Corporate Communications electronically, or wish to receive printed copies, HKEX will promptly upon your request send the Printed Version to you free of charge.

HKEX's 2020 Corporate Social Responsibility Report is published in electronic form only under the Corporate Social Responsibility (CSR Reports) section of the HKEX Group website(www.hkexgroup.com). If you wish to receive a printed copy of HKEX's 2020 Corporate Social Responsibility Report, you may submit your request to Hong Kong Registrars Limited by post at the above address or by email [e-mail].

You are encouraged to elect the Electronic Version to help protect the environment, and we believe that it is the most prompt, efficient and convenient method of communication with Shareholders. Whenever a Shareholder elects the Electronic Version, HKEX will donate HK$50 to a charity with a focus on environmental protection, subject to a cap of HK$100,000 per annum.

Should you have any queries in relation to this letter, please call the enquiry hotline of HKEX's registrar on (852) 2862 8688 during business hours (9:00 am to 6:00 pm, Monday to Friday, excluding Hong Kong public holidays).

Yours faithfully David Fu

Group Company Secretary
