UPDATE ON THE POSSIBLE PRIVATISATION

The Company wishes to update its shareholders and potential investors that, as at the date of this announcement, the Company has not received any definitive Possible Privatisation proposal from BII HK. The Company understands that BII HK is in the process of considering the terms and conditions of the Possible Privatisation and preparing certain requisite filing with, and obtaining registration or approval (as applicable) from, the relevant government or regulatory authorities in relation to the Possible Privatisation. The Company has been consulting various parties (including professional advisers) on the possible issues which may arise from the Possible Privatisation. As at the date of this announcement, no definitive agreement or other commitment has been made by BII HK as to whether to proceed with the Possible Privatisation. Accordingly, there is no certainty that the Possible Privatisation will proceed.

MONTHLY ANNOUNCEMENTS

In compliance with Rule 3.7 of the Takeovers Code, monthly announcement(s) setting out the progress of the Possible Privatisation will be made until an announcement is made of a firm intention to make an offer under Rule 3.5 of the Takeovers Code or of a decision not to proceed with the Possible Privatisation.

Further announcement(s) will be made as and when appropriate in accordance with the Listing Rules and/or the Takeovers Code (as the case may be).

WARNING: The Possible Privatisation may or may not materialise. Shareholders and investors of the Company should therefore exercise caution when dealing in the securities of the Company, and if in any doubt, they should consult their professional advisers.
