WAIVER FROM STRICT COMPLIANCE WITH RULES 3.28 AND 8.17 OF THE LISTING RULES

Pursuant to Rules 3.28 and 8.17 of the Listing Rules, the Company must appoint a company secretary who, by virtue of his/her academic or professional qualifications or relevant experience, is, in the opinion of the Stock Exchange, capable of discharging the functions of company secretary.

Notwithstanding the qualifications as required under Rule 3.28 of the Listing Rules, the Board considers that it would be beneficial to the Company to appoint Mr. Tian as the Joint Company Secretary, taking into consideration his extensive capital markets experience accumulated throughout his career, thorough understanding and management of the day-to-day corporate governance operations of the Company, as well as his long-term close cooperation with the Board, the senior management and various departments within the Company.

Ms. Chan, who possesses all the requisite qualifications under Rule 3.28 of the Listing Rules, will ensure that she is available at all times to assist Mr. Tian in discharging his duties as a Joint Company Secretary and in gaining the relevant experience as required under Note 2 to Rule 3.28 of the Listing Rules.

In light of the above, the Company has applied to the Stock Exchange and the Stock Exchange has granted a waiver (the “Waiver”) from strict compliance with the requirements under Rules 3.28 and 8.17 of the Listing Rules with respect to the appointment of Mr. Tian as a Joint Company Secretary for a term of three years commencing from the date of his appointment (the “Waiver Period”). The Waiver was granted on the conditions as follows: (i) Mr. Tian must be assisted by Ms. Chan during the Waiver Period; and (ii) the Waiver could be revoked if there are material breaches of the Listing Rules by the Company. The Stock Exchange may withdraw or change the Waiver if the Company’s situation changes.

Before the end of the Waiver Period, the Company must demonstrate and seek the confirmation from the Stock Exchange that Mr. Tian, having had the benefit of Ms. Chan’s assistance during the Waiver Period, has attained the relevant experience and is capable of discharging the function of company secretary under Rule 3.28 of the Listing Rules such that a further waiver will not be necessary.

The Board wishes to take this opportunity to extend a warm welcome to Mr. Tian and Ms. Chan on their new appointments.
