We also request that you confirm that we may on your behalf make the representations contained in the letter of transmittal that are to be made with respect to you as beneficial owner.

Pursuant to the letter of transmittal, each holder of outstanding notes will represent to City Telecom that (i) it is not an affiliate of City Telecom (H.K.)

By acknowledging that it will deliver a prospectus meeting the requirements of the Securities Act in connection with any resale of such exchange notes, such broker-dealer will not be deemed to admit that it is an “underwriter” within the meaning of the Securities Act.
