       value" is defined in paragraph (5) hereinbelow, plus any declared but
       unpaid dividends on the class "D" shares.

    (4) Voting Rights.  Subject to the provisions of the CANADA BUSINESS
       CORPORATIONS ACT, holders of class "D" shares shall not, in their
       capacity as such, be entitled to receive notices of meetings of
       shareholders of the Corporation, attend same or vote thereat.

    (5) Right of Redemption.  Subject to the provisions of subsection 36(2) of
       the CANADA BUSINESS CORPORATIONS ACT, holders of class "D" shares shall,
       at all times and upon written notice, be entitled to require the
       Corporation to redeem their shares at a price equal to the amount paid
       for these shares into the stated capital account for the class "D"
       shares, plus a premium equal to the difference between the amount paid
       for these shares into the stated capital account for the class "D" shares
       and the fair market value of the class "A" [SIC] shares upon their
       exchange for class "D" shares.

       The redemption price so determined shall be the "redemption value" of the
       class "D" shares, to which shall be added, if applicable, the amount to
       be paid by the Corporation as declared, but unpaid, dividends on the said
       class "D" shares. In establishing the value of the aforementioned
       premium, the Corporation and the holders of class "D" shares shall rely
       on the fair market value of the class "B" shares upon their exchange for
       class "D" shares.

       In case of disagreement with the federal or provincial Ministry of
       Revenue, the Ministry of Revenue's evaluation of the fair market value of
       the class "B" shares upon their exchange shall prevail, and the amount of
       the premium shall be adjusted accordingly, if the Ministry of Revenue
       provides the Corporation and the holder of class "D" shares the
       opportunity to contest its evaluation with the Ministry of Revenue or
       before the courts. In case of discrepancy between the federal and
       provincial evaluations, the amount of the premium shall be based on the
       lower of the evaluations established in accordance with an uncontested
       assessment or a final judgment, as the case may be.

       The class "D" shares which have been so redeemed at the request of a
       shareholder shall be cancelled as of their redemption date and, in
       accordance with the provisions of subsection 39(1) of the CANADA BUSINESS
       CORPORATIONS ACT, the Corporation shall reduce the stated capital account
       for the class "D" shares.

    (6) Right to Purchase.  Subject to the provisions of
       subsections 34(2) and 35(3) of the CANADA BUSINESS CORPORATIONS ACT, the
       Corporation may, when it deems it appropriate, purchase by mutual
       agreement and at the best possible price, all or part of the outstanding
       class "D" shares, the whole without being required to give a notice or
       take the other classes of shares into account. However, the purchase
       price shall not, under any circumstances, exceed the aforementioned
       redemption price or exceed the realizable value of the Corporation's net
       assets.

       The class "D" shares which have been so purchased shall be cancelled
       automatically as of their purchase date and, in accordance with the
       provisions of subsection 39(1) of the CANADA BUSINESS CORPORATIONS ACT,
       the Corporation shall reduce the stated capital account for the
       class "D" shares.

E.  CLASS "E" SHARES:  There shall be an unlimited number of class "E" shares,
    without par value, with the following rights, privileges, conditions and
    restrictions:

       class "E" shares shall be entitled to receive, in preference to holders
       of class "A", class "B", class "F", class "G" and class "H" shares, but
       after holders of class "D shares, from the funds available for the
       payment of dividends, a monthly, preferred and non-cumulative dividend
       which shall not exceed the declared dividend and which shall be equal to
       one percent (1%) per month of the "redemption value" of the class "E"
       shares, as such "redemption value" is defined in
       paragraph (5) hereinbelow. The Corporation shall not declare a dividend
       for more than one month at a time, and the directors shall determine the
       timing and the terms and conditions of payment thereof.

    (2) Repayment.  If the Corporation's assets are distributed for any reason
       whatsoever, including a dissolution, voluntary liquidation or forced
       liquidation, holders of class "E" shares shall be entitled, in preference
       to holders of class "A", class "B", class "F", class "G" and class "H"
       shares, but after holders of class "C" and class "D" shares, to the
       payment of the "redemption value" of the class "E"

       paragraph (5) hereinbelow, plus any declared but unpaid dividends on the
       class "E" shares.

       Corporation.

    (4) Voting Rights.  Subject to the provisions of the CANADA BUSINESS
       CORPORATIONS ACT, holders of class "E" shares shall not, in their

       shall, at all times and upon written notice, be entitled to require the
       Corporation to redeem all or part of his shares at a price equal to the
       amount paid for the said share(s) into the stated capital account for the
       class "E" shares, plus a premium equal to the difference between the fair
       market value of the consideration received by the Corporation upon the
       issuance of the said class "E" share(s), as consideration for the
       issuance thereof, and the total of the following amounts:

       (a) the amount paid for the said share(s) into the stated capital account
           for the class "E" shares, and

       (b) the fair market value of any property, other than a class "E" share,
           given by the Corporation as payment for such consideration.

       The redemption price so determined shall be the "redemption value" of the
       said class "E" share(s), to which shall be added, if applicable, the
       amount to be paid by the Corporation as declared, but unpaid, dividends
       on the said class "E" share(s). The Corporation and the person
       subscribing for class "E" shares shall, upon the issuance of the
       class "E" shares, mutually determine the fair market value of the
       aforementioned consideration. In case of disagreement with the federal or
       provincial Ministry of Revenue, the Ministry's evaluation of the fair
       market value of said consideration shall prevail, and the amount of the
       premium shall be adjusted accordingly, if the Ministry provides the
       Corporation and the holder of class "E" shares the opportunity to contest
       its evaluation with the Ministry or before the courts. In case of
       discrepancy between the federal and provincial evaluations, the amount of
       the premium shall be based on the lower of the evaluations established in
       accordance with an uncontested assessment or a final judgment, as the
       case may be.

       If, before the redemption price provided for in the preceding sentence is
       adjusted, the Company has paid an amount, in cash or in any other form of
       consideration, to a holder of class "E" shares, whether in connection
       with a redemption or purchase of class "E" shares either at the option of
       the holder or of the Company, and the amount so paid for the class "E"
       shares differs from the redemption price as adjusted, the holder or the
       Company, as the case may be, shall immediately pay to the holder or to
       the Company, as the case may be, the necessary amount to ensure that the
       amount paid in connection with such redemption or purchase is equal to
       the redemption price as so adjusted.

       Furthermore, if, at the time of the adjustment, dividends have already
       been declared and paid on the class "E" shares, the dividends shall be
       adjusted so as to reflect the adjustment in the redemption price.

       The Corporation shall redeem class "E" shares without taking the other
       classes of shares into account, and it shall have thirty (30) days from
       the date of redemption within which to pay the redemption price to the
       former holder of class "E" shares. If the provisions of
       subsection 36(2) of the CANADA BUSINESS CORPORATIONS ACT do not allow the
       Corporation to respect this deadline, the Corporation shall pay an
       initial portion of the redemption price within the said period of thirty
       (30) days and it shall pay any unpaid balance as soon as it is legally
       entitled to do so.

       Any class "E" share which has been so redeemed at the option of its
       holder shall be cancelled as of its redemption date and, in accordance
       with the provisions of subsection 39(1) of the CANADA BUSINESS
       CORPORATIONS ACT, the Corporation shall reduce the stated capital account
       for the class "E" shares.

    (6) Right to Purchase.  Subject to the provisions of
       subsections 34(2) and 35(3) of the CANADA BUSINESS CORPORATIONS ACT, the
       Corporation may, when it deems it appropriate, purchase by mutual
       agreement and

                                       4
<Page>
       at the best possible price, all or part of the outstanding class "E"
       shares, the whole without being required to give a notice or take the
       other classes of shares into account. However, the purchase price shall
       not, under any circumstances, exceed the aforementioned redemption price
       or exceed the realizable value of the Corporation's net assets.

       The class "E" shares which have been so purchased shall be cancelled
       automatically as of their purchase date and, in accordance with the
       provisions of subsection 39(1) of the CANADA BUSINESS CORPORATIONS ACT,
       the Corporation shall reduce the stated capital account for the
       class "E" shares.

       the redemption request, and it shall have thirty (30) days following such
       date within which to pay the redemption price to the former holders of
       class "F" shares. If the provisions of subsection 36(2) of the CANADA
       BUSINESS CORPORATIONS ACT do not allow the Corporation to respect this
       deadline, the Corporation shall pay an initial portion of the redemption
       price within the said period of thirty (30) days and it shall pay any
       unpaid balance as soon as it is legally entitled to do so.

       The class "F" shares which have been so redeemed at the request of a
       shareholder shall be cancelled as of their redemption date and, in
