Pursuant to Chapter 38 of the Rules Governing the Listing of Securities on The Stock Exchange of Hong Kong Limited, the Securities and Futures Commission regulates Hong Kong Exchanges and Clearing Limited in relation to the listing of its shares on The Stock Exchange of Hong Kong Limited.

Scrip Dividend Scheme in relation to the Final Dividend for the year ended 31 December 2017

Calculation of Market Value

At HKEX's annual general meeting held on 25 April 2018, the Shareholders approved the payment of the Final Dividend, as recommended by the Board, which will be payable in cash with a scrip alternative to the Shareholders whose names appeared on HKEX's register of members on the Record Date. Pursuant to the Scrip Dividend Scheme and subject to the terms set out in the Circular, the eligible Shareholders have the right to elect to receive the Final Dividend in New Shares instead of in cash, or partly in New Shares and partly in cash.

In addition, the eligible Shareholders have the right to choose to receive new Shares instead of cash for all future dividends to be paid by HKEX if a scrip alternative is available to them, until they revoke such election by notice in writing to the Share Registrar.

The Market Value for the issue of each New Share is equivalent to 97% of the average closing price per Share as quoted on the Stock Exchange for the five (5) consecutive trading days commencing on 9 May until 15 May 2018 (both dates inclusive). On this basis, the average closing price is now determined to be HK$260.8, and therefore the Market Value for the calculation of the scrip entitlement is HK$252.976.

The number of New Shares which an eligible Shareholder electing a scrip alternative will receive in respect of the Final Dividend that he/she is entitled will be calculated as follows:

Number of New Shares to be received (rounded down to the nearest whole number)Number of registered

Final Dividend per Share

(HK$2.85)

X

Market Value per New Share

(HK$252.976)Fractional entitlements to the New Shares will not be issued and the residual dividend entitlement, if any, will be paid in cash (rounded down to the nearest cent) to the relevant Shareholders.

Based on 1,239,809,477 Shares in issue on the Record Date, if all Shareholders choose to receive the Final Dividend in the form of New Shares instead of cash, HKEX will issue approximately 13,967,558 New Shares, representing approximately 1.13% of the total Shares in issue (1,239,809,477 Shares) as at the date of this announcement.

No action is required by the following Shareholders:

(A)Shareholders who have not made a Permanent Election and wish to receive the Final Dividend in cash only; and

(B) Shareholders who have made a Permanent Election and do not intend to revoke it in order to receive the Final Dividend in cash.

Shareholders who have not made a Permanent Election and wish to receive their Final Dividend wholly or partly in New Shares instead of in cash and, where applicable, to make a Permanent Election should complete the Election Form. Shareholders who have previously made a Permanent Election and wish to receive their Final Dividend wholly or partly in cash should complete the Revocation Notice. The completed Election Form or Revocation Notice (as the case may be) should be returned as soon as possible so as to enable it to be received by the Share Registrar before the Closing Time. Late submissions of the Election Form or the Revocation Notice will not be accepted.

Shareholders who are not eligible to receive the Final Dividend in New Shares under the provisions of the Scrip Dividend Scheme should not complete the Election Form and, if they do so, such Election Form will be voided and have no effect.

The Closing Time will be extended, as the case may be, in accordance with (a) or (b) below if a Typhoon Signal No. 8 or above is hoisted, or a Black Rainstorm Warning Signal is in force in Hong Kong:

(a) at any time before 12:00 noon on Friday, 25 May 2018. In such a case, the closing time for the return of the Election Form and Revocation Notice will be extended to 5:00 pm on the same business day; or

(b)

at any time between 12:00 noon and 4:30 pm on Friday, 25 May 2018. In such a case, the closing time for the return of the Election Form and Revocation Notice will be extended to 4:30 pm on the next business day (excluding Saturday) where none of the above signals is hoisted or in force at any time between 9:00 am and 4:30 pm.

HKEX has applied to the SFC for the listing of, and permission to deal in, the New Shares. It is expected that the dividend warrants and/or, subject to the SFC's approval of the above application, definitive certificates for the New Shares will be despatched by ordinary mail to the respective Shareholders concerned at their own risk on Friday, 1 June 2018. The New Shares will, on issue, rank equally in all other respects with the existing Shares save that they will not be eligible for the Final Dividend.

Subject to the proper receipt of definitive certificates for the New Shares by the relevant Shareholders, dealings in the New Shares on the Stock Exchange are expected to commence on Friday, 1 June 2018.
