as amended (the "Securities Act"), for a like stated amount at maturity of its

November 19, 2004 (the "Old Notes") upon the terms and subject to the conditions
set forth in the Exchange Offer.

    PLEASE NOTE THAT THE EXCHANGE OFFER WILL EXPIRE AT 5:00 P.M., NEW YORK CITY
TIME, ON     -    , 2005, UNLESS EXTENDED BY VIDEOTRON IN ITS SOLE DISCRETION.

    THE EXCHANGE OFFER IS NOT CONDITIONED UPON ANY MINIMUM NUMBER OF OLD NOTES
BEING TENDERED.

    We are the holder of record of Old Notes held by us for your account. A
tender of such Old Notes can be made only by us as the record holder and
pursuant to your instructions. The letter of transmittal is furnished to you for
your information only and cannot be used by you to tender Old Notes held by us
for your account.

    We request instructions as to whether you wish to tender any or all of the
Old Notes held by us for your account pursuant to the terms and conditions of
the Exchange Offer. Please so instruct us by completing, executing and returning
to us the Instruction to Registered Holder from Beneficial Holder enclosed
herewith. We also request that you confirm with such instruction form that we
may on your behalf make the representations contained in the letter of
transmittal.

    Pursuant to the letter of transmittal, each holder of Old Notes will
represent to Videotron that (i) the New Notes acquired in the Exchange Offer are
being obtained in the ordinary course of business of the person receiving such
New Notes, whether or not such person is such holder, (ii) neither the holder of
the Old Notes nor any such other person has an arrangement or understanding with
any person to participate in the distribution of such New Notes, (iii) if the
holder or any such other person is not a broker-dealer or is a broker-dealer but
will not receive New Notes for its own account in exchange for Old Notes, it is
not engaged in and does not intend to participate in a distribution of the
New Notes and (iv) neither the holder nor any such other person is an
"affiliate" of Videotron within the meaning of Rule 405 under the Securities Act
or, if such person is an "affiliate," that such person may not rely on the
applicable interpretations of the staff of the U.S. Securities and Exchange
Commission set forth in no-action letters to third parties described under "The
Exchange Offer -- Resale of the New Notes" in the Prospectus and will comply
with the registration and prospectus delivery requirements of the Securities Act
to the extent applicable. If the tendering holder or any such other person is a
broker-dealer (whether or not it is also an "affiliate" of Videotron within the
meaning of Rule 405 under the Securities Act) that will receive New Notes for
its own account in exchange for Old Notes, we will represent on behalf of such
broker-dealer that the Old Notes to be exchanged for the New Notes were acquired
by it as a result of market-making activities or other trading activities, and
acknowledge on behalf of such broker-dealer that it will deliver a prospectus
meeting the requirements of the Securities Act in connection with any resale of
such New Notes. By acknowledging that it will deliver and by delivering a
prospectus meeting the requirements of the Securities Act in connection with any
resale of such New Notes, a broker-dealer will not be deemed to admit that it is
an "underwriter" within the meaning of the Securities Act.
