                             SUBORDINATION AGREEMENT

                  WITNESSES THAT WHEREAS:

A.       The Company (formerly known as Rogers Cablesystems Limited), certain
         affiliates of the Company that were then Designated Subsidiaries

         and National Trust Company, as trustee.

B.       The Company and the 2003 Note Trustee entered into an indenture (the
         "2003 Note Indenture"), dated as of the date hereof, providing for the
         issuance of the Company's 6.25% Senior (Secured) Second Priority Notes
         due 2013 (the "2003 Notes").

C.       Pursuant to section 1207 of the Subordinated Debt Indenture, the
         Company has furnished an Officers' Certificate (as such term is defined
         in the Subordinated Debt Indenture) to the Subordinated Debt Trustee
         (i) stating that the 2003 Note Trustee is trustee on behalf of holders
         of Senior Indebtedness (as such term is defined in the Subordinated
         Debt Indenture) and (ii) directing the Subordinated Debt Trustee to
         execute and deliver this Agreement.

                  NOW THEREFORE for good and valuable consideration (the receipt
and sufficiency of which are hereby acknowledged), the parties hereto agree as
follows:

1.       SUBORDINATION

                  The Subordinated Debt Trustee, under the authority granted to
it in the Subordinated Debt Indenture and as trustee on behalf of the holders of
the Subordinated Securities, the Company and each of the Restricted Subsidiaries
hereby covenant with the 2003 Note Trustee, in its capacity as trustee on behalf

                                     - 2 -


represented by each and all of the Guarantees (as such term is defined in the
Subordinated Debt Indenture) delivered from time to time under the Subordinated
Debt Indenture and (iv) the payment of the Guaranteed Obligations (as such term
is defined in such Guarantees) thereunder are all subordinate and subject in
right of payment to the prior payment in full of indebtedness, premium (if any),
interest and fees and expenses owing to the holders of the 2003 Notes and the
2003 Note Trustee, as trustee on their behalf, under the 2003 Notes and the 2003
Note Indenture, in the manner, to the same extent and with the same effect as if
the terms and provisions of the Subordinated Debt Indenture and such Guarantees
were set forth herein.

2.       PAYMENT TO THE COMPANY IN CERTAIN CIRCUMSTANCES

                  In accordance with section 1205 of the Subordinated Debt
Indenture, if any holder of the 2003 Notes or the 2003 Note Trustee, as trustee
on behalf of the holders of the 2003 Notes, (each, a "Recipient") shall receive
any amount under this Agreement and, at the time of receipt, such Recipient is
not entitled to such amount under the terms of the 2003 Note Indenture and the
2003 Notes (whether by reason of maturity, acceleration or otherwise), then such
Recipient shall turn over such amount to the Company. Any such amount so
received by any Recipient which it is required to turn over to the Company
pursuant to this section 2 shall, in no circumstances, be considered to be a
payment on account of the Senior Indebtedness represented by the 2003 Notes.

3.       BINDING EFFECT AND ENUREMENT

                  This Agreement shall be binding upon the successors of the
Company, each of the Restricted Subsidiaries and the Subordinated Debt Trustee,

enure to the benefit of the successors and permitted assigns of the 2003 Note
Trustee, as trustee on behalf of the holders of the 2003 Notes.

4.       NO WAIVER OR AMENDMENT

                  No provision of this Agreement may be waived or amended except
by an instrument in writing signed by the party hereto against which the
enforcement of any waiver or amendment is sought.

5.       NO PERSONAL LIABILITY

                  Neither the Subordinated Debt Trustee nor the 2003 Note
Trustee makes any representation or warranty as to the validity, sufficiency or
effect of this Agreement or as to its authority to execute and deliver this
Agreement. Neither the Subordinated Debt Trustee nor the 2003 Note Trustee shall
have any personal responsibility or liability with respect to the covenant
contained in section 1 hereof.

6.       COUNTERPARTS

instrument.
