Summary of Material Change

Rogers Communications Inc. ("RCI") and Rogers Telecom, a wholly owned subsidiary of RCI and formerly Call-Net Enterprises Inc., announced today that Rogers Telecom is commencing a cash tender offer (the "Tender Offer") for any and all of its US$222.9 million aggregate principal amount of 10.625% Senior Secured Notes due 2008 (CUSIP No. 130910AJ1) (the "Notes") and a consent solicitation (the "Solicitation") to amend the related indenture.

Rogers Telecom is making the Tender Offer in order to acquire the outstanding Notes and eliminate the associated interest expense. The consents are being solicited to eliminate substantially all of the restrictive covenants, certain events of default and related provisions contained in the indenture governing the Notes. Rogers Telecom intends to finance the Tender Offer and the Solicitation, together with the fees and expenses incurred in connection therewith, with proceeds contributed to it by RCI, which proceeds will be comprised of distributions and/or repayment of intercompany advances from one or more operating subsidiaries of RCI. The subsidiaries will use drawdowns under revolving term bank credit facilities and cash on hand to fund the distributions and/or repayment of intercompany advances to RCI.

Holders should consult the Statement and related materials in their entirety for a full description of the terms and conditions of the Tender Offer and the Solicitation.

The total consideration to be paid for each $1,000 principal amount of Notes validly tendered and accepted for payment will be a price, calculated in accordance with standard market practice as described in the Statement, intended to result in a yield to the earliest redemption date for the Notes (January 1, 2006) equal to the sum of (i) the bid-side yield to maturity on the 1.875% U.S. Treasury Note due December 31, 2005, as calculated by the dealer manager and solicitation agent in accordance with standard market practice as of 2:00 p.m., New York City time, on September 13, 2005, unless such date is extended, as reported on the Bloomberg Government Pricing Monitor on Page PX3, and (ii) a fixed spread of 50 basis points, which consideration includes a consent payment of $30 for each $1,000 principal amount of Notes validly tendered. Holders also will be paid accrued and unpaid interest to, but not including, the settlement date. Holders that tender Notes after the Consent Payment Deadline will not be eligible to receive the consent payment. Promptly following the final calculation of the consideration for the Notes, Rogers Telecom will publicly announce, by press release, the pricing information. The initial settlement date is expected to be September 14, 2005.
