In addition, the Company shall notify the Stock Exchange at the end of the New Waiver Period for the Stock Exchange to re-visit the situation, as the Stock Exchange expects that after the end of the New Waiver Period, the Company will be able to demonstrate that Mr. Cao can satisfy Rule 3.28 of the Listing Rules after having the benefit of Mr. Wong's assistance such that a further waiver will not be necessary.
