The key clawback terms are as follow:

In the event that an Award Grantee (a) ceases to be an eligible participant by reason of termination for cause or without notice, or the result of being charged/penalised/ convicted of an offence involving the Award Grantee's integrity or honesty; (b) commits a serious misconduct or breach, including with respect to a policy or code of or other agreement with our Group, which is considered to be material; (c) he/she, in the reasonable opinion of the Board, has engaged in serious misconduct or breaches the terms of the 2023 Share Incentive Plan in any material respect; or (d) the award is no longer determined to be appropriate and aligned with the purpose of the 2023 Share Incentive Plan, then the Board may make a determination at its absolute discretion that: (A) any awards issued to that Award Grantee but not yet exercised shall immediately lapse, regardless of whether such awards have vested or not, (B) with respect to any Shares delivered or Actual Selling Price paid to that Award Grantee, the Award Grantee shall be required to transfer back to the Company or its nominee (1) the equivalent number of Shares, (2) an amount in cash equal to the market value of such Shares or the Actual Selling Price, or (3) a combination of (1) and (2).

Listing Rules implications

Under the Award Grants (i) none of the other Award Grantees is a Director, chief executive or substantial shareholder of the Company, or any of their respective associates; (ii) none of the Award Grantees is a participant with options and share awards granted and to be granted exceeding the 1% individual limit under Rule 17.03D(1) of the Listing Rules; (iii) none of the Award Grantees is a related entity participant (as defined under the Listing Rules); and (iv) no financial assistance has been provided by the Group to the Award Grantees for the purchase of Shares under the 2023 Share Incentive Plan. None of the Award Grants will be subject to approval by the Shareholders.

Reasons for and benefits of the Award Grants

The reasons for the Award Grants are to provide incentives for the Award Grantees to exert maximum efforts and reward continued efforts for the success of the Company and its affiliates, and to provide a means by which the Award Grantees may be given an opportunity to benefit from increases in value of the Shares through the granting of the Award Shares.
