Explanation of Responses:

* If the form is filed by more than one reporting person, see Instruction 4(b)(v).
** Intentional misstatements or omissions of facts constitute Federal Criminal Violations. See 18 U.S.C. 1001 and 15 U.S.C. 78ff(a).
(1) These securities were omitted from the reporting persons' Forms 4 filed prior to the date hereof. These securities have been reported on prior Schedules 13D filed by the reporting persons, and as such do not affect the calculations of the reporting persons' pecuniary interests in the Issuer.
(2) The Issuer's 14% Series A-1 Payment-Of-Interest-In-Kind Convertible Secured Notes Due 2007 listed herein (the "PIK Notes"), together with all dividends accrued thereon between the date of issue and November 1, 2007, are convertible into Common Shares of the Issuer at an exercise price of $9.18.
(3) Singapore Technologies Telemedia Pte Ltd ("STT"), a wholly-owned indirect subsidiary of Temasek Holdings (Private) Limited ("Temasek"), has an indirect interest in the securities reported herein by virtue of its ownership interest in i-STT Investments Pte Ltd, which is the record holder of the securities of the Issuer reported herein. In addition, Temasek holds an indirect interest in 11,718 shares owned beneficially and of record by T.H.e. Venture Pte Ltd. Temasek disclaims beneficial ownership of such securities except to the extent of its pecuniary interest therein.
(4) In connection with an internal restructuring to be completed on December 31, 2004, the shares of STT presently owned by Singapore Technologies Private Limited ("STPL"), will be transferred to Temasek with effect from December 31, 2004. Accordingly, STPL will cease to be a reporting person with effect from December 31, 2004.
(5) This is the face amount of the debt securities expressed in U.S. dollars.
