For H Shareholders, the proxy forms shall be provided to the Company’s Share Registrar, Union Registrars Limited at Suites 3301-04, 33/F., Two Chinachem Exchange Square, 338 King ’s Road, North Point, Hong Kong, whereas for A Shareholders, the proxy forms shall be provided to the Company instead. Completion and return of a proxy form for the AGM and/or the H Shareholders Class Meeting will not preclude an Independent H Shareholder from attending the AGM and/or the H Shareholders Class Meeting and, as the case may be, voting in person if he/she/it so wishes and if such Independent H Shareholder has notified the Company not less than 24 hours in writing before the time appointed for any adjournment of the AGM and the H Shareholders Class Meeting. In such event, the returned proxy form will be deemed to have been revoked. 3. The procedures for acceptance and settlement of the Share Buy-back Offer and related information are set out in Appendix I to the Offer Document and in the Form of Acceptance. Acceptances of the Share Buy-back Offer should be received by the Share Registrar, Union Registrars Limited at Suites 3301-04, 33/F., Two Chinachem Exchange Square, 338 King’s Road, North Point, Hong Kong, as soon as possible and in any event by no later than 4:00 p.m. on 21 July 2022 or such later time(s) and/or date(s) as the Company may determine and announce, with the consent of the Executive, in accordance with the Takeovers Code. 4. The Company will issue an announcement on the Company’s and Stock Exchange’s website by 7:00 p.m. on the First Closing Date stating the results of the Share Buy-back Offer and the Voluntary Withdrawal of Listing and whether the Share Buy-back Offer has been revised or extended, have expired or have become or been declared unconditional. –5– 5. Remittances in respect of the cash consideration under the Share Buy-back Offer will be posted to the accepting Independent H Shareholders by ordinary post at their own risk as soon as possible but in any event within seven (7) Business Days following the later of the date of receipt by the Share Registrar, of duly completed Form of Acceptance and the relevant documents, or on the date the Share Buy-back Offer and Voluntary Withdrawal of Listing become or are declared unconditional. 6. In compliance with the note to Rule 2.2 and Rule 15.3 of the Takeovers Code, the Share Buy-back Offer will remain open for acceptance for 28 days which is a longer period than normally required by Rule 15.3 of the Takeovers Code after it has been declared unconditional in all respects. At least 14 days’ notice in writing must be given before the Share Buy-back Offer is closed to the H Shareholders who have not yet accepted the Share Buy-back Offer. Hence, the latest time to receive acceptances under the Share Buy-back Offer will be 4:00 p.m. on 18 August 2022. WARNING H Shareholders and potential investors of the Company should note that the Share Buy- back Offer is subject to the satisfaction of the Conditions in all respects. Accordingly, the Share Buy-back Offer may or may not become unconditional. H Shareholders and potential investors of the Company should therefore exercise caution when dealing in the securities of the Company. Persons who are in doubt as to the action they should take should consult their licensed securities dealers or registered institutions in securities, bank managers, solicitors, professional accountants or other professional advisers. The Directors make no recommendation as to the fairness or reasonableness of the Share Buy-back Offer and the Voluntary Withdrawal of Listing or as to the acceptance of the Share Buy-back Offer in this announcement, and strongly recommend the Independent H Shareholders not to form a view on the Share Buy-back Offer and the Voluntary Withdrawal of Listing, unless and until they have received and read the letter from the Independent Financial Adviser containing its advice to the Independent H Shareholders in respect of the Share Buy-back Offer and the Voluntary Withdrawal of Listing, which is included in the Offer Document despatched to the Shareholders on 6 June 2022. Independent H Shareholders are reminded that if they do not accept the Share Buy-back Offer, and if the Share Buy-back Offer subsequently becomes unconditional in all respects and the H Shares are delisted from the Stock Exchange, this will result in the Independent H Shareholders holding unlisted H Shares and the liquidity of the H Shares may be severely reduced. In addition, the Company will no longer be subject to the requirements under the Listing Rules and may or may not continue to be subject to the Takeovers Code (depending on whether it remains as a public company in Hong Kong under the Takeovers Code) after the completion of the Share Buy-back Offer, and the rights of Independent H Shareholders to certain information of the Company will be reduced. –6– Shareholders should also note that if they do not agree to the terms of the Share Buy-back Offer, they can vote against the Share Buy-back Offer and the Voluntary Withdrawal of Listing at the H Shareholders Class Meeting, A Shareholders Class Meeting and/or the AGM (as the case may be). If more than 10% of the votes attaching to all the H Shares held by the Independent H Shareholders are voted against the Share Buy-back Offer and the Voluntary Withdrawal of Listing at the H Shareholders Class Meeting, the Share Buy-back Offer would lapse and the H Shares would remain listed on the Stock Exchange.
