                            SUBORDINATION AGREEMENT

    This SUBORDINATION AGREEMENT is dated as of January 16, 2004 (the
"Agreement").

     Indenture referred to below for the holders of the Notes (the "Trustee")

    Videotron (1998) ltee (the "Obligor"), as obligor under a subordinated loan
agreement dated as of January 16, 2004 entered into by the Obligor and Quebecor

1.  INTERPRETATION.

    (a) "Cash, Property or Securities". "Cash, Property or Securities" shall not
be deemed to include securities of the Obligor or any other Person provided for
by a plan of reorganization or readjustment, the payment of which is
subordinated at least to the extent provided herein with respect to the
Subordinated Security, to the payment of all Senior Indebtedness which may at
the time be outstanding; provided, however, that (i) all Senior Indebtedness is
assumed by the new Person, if any, resulting from any such reorganization or
readjustment, and (ii) the rights of the holders of the Senior Indebtedness are
not, without the consent of such holders, altered by such reorganization or
readjustment.

    (b) "payment in full". "payment in full", with respect to Senior
Indebtedness, means the receipt on an irrevocable basis of cash in an amount
equal to the unpaid principal amount of the Senior Indebtedness and premium, if
any, and interest and any special interest thereon to the date of such payment,
together with all other amounts owing with respect to such Senior Indebtedness.

    (c) "Representative" means the agent (including an administrative agent),
trustee or representative of holders of Senior Indebtedness.

    (d) "Senior Indebtedness". "Senior Indebtedness" means, at any date, all
indebtedness (including, without limitation, any and all amounts of principal,
interest, special interest, additional amounts, premium, fees, penalties,
indemnities and "post-petition interest" in bankruptcy and any reimbursement of
expenses) under (1) the Indenture, including, without limitation, the "Notes,"
the "Subsidiary Guarantees," the "Exchange Notes," the "Additional Notes" and
any "guarantee" of the Exchange Notes or the Additional Notes (in each case, as
defined in the Indenture) and (2) any Credit Facilities (as defined in the
Indenture) of Videotron ltee ("Videotron").

2.  AGREEMENT ENTERED INTO PURSUANT TO INDENTURE.  The Obligor and the Holder
are entering into this Agreement pursuant to the provisions of the Indenture,
dated as of October 8, 2003 (the "Indenture"; capitalized terms used herein
without definition having the meanings set forth therein) among Videotron, the
Subsidiary Guarantors and the Trustee. Pursuant to the Indenture, Videotron has
issued and the Subsidiary Guarantors have guaranteed, 6 7/8% Senior Notes due
January 15, 2014 of Videotron.

3.  SUBORDINATION.  The indebtedness or obligation represented by the
Subordinated Security shall be subordinated as follows:

    (a) Agreement to Subordinate.  The Obligor, for itself and its successors
and assigns, and the Holder agree, that the indebtedness or obligation evidenced
by the Subordinated Security (including, without limitation, principal,
interest, premium, redemption or retraction amount, dividend, fees, penalties,
indemnities and "post-petition interest" in bankruptcy and any reimbursement of
expenses) is subordinate and junior in right of payment, to the extent and in
the manner provided in this Section 3, to the prior payment in full of all
Senior Indebtedness. The provisions of this Section 3 are for the benefit of the
Trustee and/or other Representative acting on behalf of the holders from time to
time of Senior Indebtedness, and such holders are hereby made obligees hereunder
to the same extent as if their names were written herein as such, and they
(collectively or singly) may proceed to enforce such provisions.

             bankruptcy, arrangement, liquidation, reorganization, insolvency,
             receivership or similar case or proceeding relating to the Obligor
             or its property or other marshalling of assets of the Obligor:

           (A) the holders of Senior Indebtedness shall be entitled to receive
              payment in full of all Senior Indebtedness before the Holder shall
              be entitled to receive any payment of any amount owing in respect
              of the Subordinated Security (including, without limitation,
              principal, interest, premium, redemption or retraction amount, or
              dividend);

           (B) until payment in full of all Senior Indebtedness, any
              distribution of assets of the Obligor of any kind or character to
              which the Holder would be entitled but for this Section 3 is
              hereby assigned absolutely to the holders of Senior Indebtedness
              (equally and ratably among the holders of Senior Indebtedness) and
              shall be paid by the Obligor or by any receiver, trustee in
              bankruptcy, liquidating trustee, agents or other Persons making
              such payment or distribution to the Trustee and/or other
              Representative on behalf of the holders of Senior Indebtedness, as
              their interests may appear; and

           (C) in the event that, notwithstanding the foregoing, any payment or
              distribution of assets of the Obligor of any kind or character,
              whether in Cash, Property or Securities, shall be received by the
              Holder before all Senior Indebtedness is paid in full, such
              payment or distribution shall be held in trust for the benefit of
              and shall be paid over to the Trustee and/or other Representative
              on behalf of the holders of Senior Indebtedness (equally and
              ratably among the holders of Senior Indebtedness), as their
              interests may appear, for application to the payment of all Senior
              Indebtedness until all Senior Indebtedness shall have been paid in
              full after giving effect to any concurrent payment or distribution
              to the holders of Senior Indebtedness in respect of such Senior
              Indebtedness.

        (ii) If (A) a bankruptcy, reorganization, insolvency, receivership or
             similar proceeding relating to the Obligor or its property (a
             "Reorganization Proceeding") is commenced and is continuing and
             (B) the Holder does not file proper claims or proofs of claim in
             the form required in a Reorganization Proceeding prior to 45 days
             before the expiration of the time to file such claims, then
             (1) upon the request of the Trustee, the Holder shall file such
             claims and proofs of claim in respect of the Subordinated Security
             and execute and deliver such powers of attorney, assignments and
             proofs of claim or proxies as may be directed by the Trustee to
             enable it to exercise in the sole discretion of the Trustee any and
             all voting rights attributable to the Subordinated Security which
             are capable of being voted (whether by meeting, written resolution
             or otherwise) in a Reorganization Proceeding and enforce any and
             all claims upon or in respect of the Subordinated Security and to
             collect and receive any and all payments or distributions which may
             be payable or deliverable at any time upon or in respect of the
             Subordinated Security, and (2) whether or not the Trustee shall
             take the action described in clause (1) above, the Trustee shall
             nevertheless be deemed to have such powers of attorney as may be
             necessary to enable the Trustee to exercise such voting rights,
             file appropriate claims and proofs of claim and otherwise exercise
             the powers described above for and on behalf of the Holder.

    (c) Relative Rights.  This Section 3 defines the relative rights of the
Holder and the holders of Senior Indebtedness. Nothing in this Section 3 shall:

         (i) impair, as between the Obligor and the Holder, the obligation of
             the Obligor, which is absolute and unconditional, to make the
             payments required by the Subordinated Security in accordance with
             its terms; or

        (ii) affect the relative rights of the Holder and creditors of the
             Obligor other than the holders of Senior Indebtedness; or

        (iii) affect the relative rights of the holders of Senior Indebtedness
              among themselves; or

        (iv) prevent the Holder from exercising its available remedies upon a
             default, subject to the rights of the holders of Senior
             Indebtedness to receive cash, property or other assets otherwise
             payable to the Holder.

    (d) Subordination May Not Be Impaired.

         (i) No right of any holder of Senior Indebtedness to enforce the
             subordination of indebtedness or obligation evidenced by the
             Subordinated Security shall in any way be prejudiced or impaired by
             any act or failure to act by the Obligor or by any such holder or
             the Trustee, or by any non-compliance by the Obligor with the
             terms, provisions or covenants herein, regardless of any knowledge
             thereof which any such holder or the Trustee may have or be
             otherwise charged with. Neither the subordination of the
             Subordinated Security as herein provided nor the rights of the
             holders of Senior Indebtedness with respect hereto shall be
             affected by any extension, renewal or modification of the terms, or
             the granting of any security in respect of, any Senior Indebtedness
             or any exercise or non-exercise of any right, power or remedy with
             respect thereto.

        (ii) The Holder agrees that all indebtedness or obligation evidenced by
             the Subordinated Security will be unsecured by any Lien upon or
             with respect to any property of the Obligor.

        (iii) The Holder agrees not to exercise any offset or counterclaim or
              similar right in respect of the indebtedness or obligation
              evidenced by the Subordinated Security except to the extent
              payment of such indebtedness or obligation is permitted and will
              not assign or otherwise dispose of the Subordinated Security or
              the indebtedness or obligation which it evidences unless the
              assignee or acquiror, as the case may be, agrees to be bound by
              the terms of this Agreement.

    (e) Holder Entitled to Rely.  Upon any payment or distribution pursuant to
this Section 3, the Holder shall be entitled to rely (i) upon any order or
decree of a court of competent jurisdiction in which any proceedings of the
nature referred to in Section 3(b) are pending, (ii) upon a certificate of the
liquidating trustee or agent or other person in such proceedings making such
payment or distribution to the Holder or its representative, if any, or
(iii) upon a certificate of the Trustee and/or other Representative (if any) of
the holders of Senior Indebtedness for the purpose of ascertaining the persons
entitled to participate in such payment or distribution, the holders of the
Senior Indebtedness and other indebtedness of the Obligor, the amount thereof or
payable thereon, the amount or amounts paid or distributed thereon and all other
facts pertinent thereto or to this Section 3.
