Subject to satisfaction of the conditions set out above, the proposed Name Change will take effect from the date on which the Registrar of Companies in Bermuda enters the Company’s new English name on the register maintained by the Registrar of Companies in Bermuda in place of the existing English name. Upon the Name Change becoming effective, the Company will comply with the necessary filing procedures in Hong Kong.

Accordingly, there will not be any arrangement for free exchange of existing share certificates of the Company for new share certificates (in “yellow” colour) under the new name of the Company.

Further announcement(s) will be made by the Company regarding the effective date of the Name Change and the change of the stock short name for trading of the Shares on the Stock Exchange.
