2. Please set out all changes in issued shares or treasury shares requiring disclosure pursuant to Main Board Rule 13.25A / GEM Rule 17.27A together with the relevant dates of

changes. Each category will need to be disclosed individually with sufficient information to enable the user to identify the relevant category in the listed issuer's Monthly Return. For

example multiple issues of shares as a result of multiple exercises of share options under the same share option scheme or of multiple conversions under the same convertible note

must be aggregated and disclosed as one category. However if the issues resulted from exercises of share options under 2 share option schemes or conversions of 2 convertible

notes these must be disclosed as 2 separate categories.

3. The percentage change in the number of issued shares (excluding treasury shares) of the listed issuer is to be calculated by reference to the opening balance of the number of issued

shares (excluding treasury shares) being disclosed in this Next Day Disclosure Return.Page 3 of 12 v 1.3.0FF305

4. In the case of a share repurchase or redemption the “issue/ selling price per share” shall be construed as “repurchase price per share” or “redemption price per share”.

Where shares have been issued/ sold/ repurchased/ redeemed at more than one price per share a volume-weighted average price per share should be given.

5. The closing balance date is the date of the last relevant event being disclosed.

6. For repurchase or redemption of shares disclosure is required when the relevant event has occurred (subject to the provisions of Main Board Rules 10.06(4)(a) 13.25A and 13.31 /

GEM Rules 13.13(1) 17.27A and 17.35) even if the repurchased or redeemed shares have not yet been cancelled.If repurchased or redeemed shares are to be cancelled upon settlement of such repurchase or redemption after the closing balance date they shall remain part of the issued shares as

at the closing balance date in Part A. Details of these repurchased or redeemed shares shall be disclosed in Part B.

7. Items (i) to (viii) are suggested forms of confirmation. The listed issuer may amend the item(s) that is/are not applicable to meet individual cases.

8. “Identical” means in this context:

- the securities are of the same nominal value with the same amount called up or paid up;

- they are entitled to dividend/interest at the same rate and for the same period so that at the next ensuing distribution the dividend/interest payable per unit will amount to

exactly the same sum (gross and net); and

即使該等購回/贖回股份尚未被註銷。

若購回/贖回股份將於期終結存日期之後購回/贖回結算完成之時予以註銷，則該等購回/贖回股份仍屬A部所述期終結存當日的已發行股份的一部分。該等購回/贖回股份的詳情應在B部作出披露。

7. (i)至 (viii)項為確認内容的建議格式。上市發行人可按個別情況就不適用的項目予以修訂。

8.在此「相同」指：
