The single most important thrust of the required standard of dealings is that directors who are aware of or privy to any negotiations or agreements related to intended acquisitions or disposals which are notifiable transactions under Chapter 19 or connected transactions under Chapter 20 of the GEM Listing Rules or any inside information must refrain from dealing in the issuer's securities as soon as they become aware of them or privy to them until the information has been announced. Directors who are privy to relevant negotiations or agreements or any inside information should caution those directors who are not so privy that there may be inside information and that they must not deal in the issuer's securities for a similar period.
