This Chapter does not apply to debt issues to professional investors only. All other issuers and guarantors, in the cases of guaranteed issues, are required to sign a Listing Agreement with the Exchange in the form prescribed and provided by the Exchange by which they undertake to comply with the continuing obligations to which they will be subject as a condition of the listing of their debt securities. These obligations are designed to ensure that issuers keep the holders of their debt securities (and the public) fully informed of all factors which might affect their interests and treat the holders of their debt securities in a proper manner.
