Notes to Section I:

1. Where shares have been issued at more than one issue price per share, a weighted average issue price per share should be given.
2. Please insert the closing balance date of the last Next Day Disclosure Return published pursuant to rule 13.25A or Monthly Return pursuant to rule 13.25B, whichever is the later.

For Main Board listed issuers

1. Please set out all changes in issued share capital requiring disclosure pursuant to rule 13.25A together with the relevant dates of issue. 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.
2. The percentage change in the listed issuer's issued share capital is to be calculated by reference to the listed issuer's total issued share capital (excluding for such purpose any shares repurchased or redeemed but not yet cancelled) as it was immediately before the earliest relevant event which has not been disclosed in a Monthly Return or Next Day Disclosure Return.
3. Where trading in the shares of the listed issuer has been suspended, "closing market price per share of the immediately preceding business day" should be construed as "closing market price per share of the business day on which the shares were last traded".
4. In the context of a repurchase of shares:
5. • "issues of shares" should be construed as "repurchases of shares"; and
   • "issued shares as a % of existing issued share capital before relevant share issue" should be construed as "repurchased shares as a % of existing issued share capital before relevant share repurchase".
6. In the context of a redemption of shares:
7. • "issues of shares" should be construed as "redemptions of shares";
   • "issued shares as a % of existing issued share capital before relevant share issue" should be construed as "redeemed shares as a % of existing issued share capital before relevant share redemption"; and
   • "issue price per share" should be construed as "redemption price per share".
8. The closing balance date is the date of the last relevant event being disclosed.
