To maintain high standards of disclosure, the Exchange may require an issuer to announce further information, and impose additional requirements on it, where the Exchange considers that circumstances so justify. However, the Exchange will allow the issuer to make representations before imposing any requirements on it which are not imposed on listed issuers generally. The issuer must comply with the additional requirements failing which the Exchange may itself publish the information available to it. Conversely, the Exchange may be prepared to waive, vary or not require compliance with the terms of the Listing Agreement in a particular case, but may require the issuer to enter into an ancillary agreement as a condition of such dispensation.
