                                   SCHEDULE 1

                            ARTICLES OF INCORPORATION

THE CLASSES OF SHARES THAT THE CORPORATION IS AUTHORIZED TO ISSUE

      The Corporation is authorized to issue Class "A" shares, Class "B" shares,
Class "C" shares, Class "D" shares, Class "E" shares, Class "F" shares and Class
"G" shares.

      The rights, privileges, restrictions and conditions attaching to the said
Class "A" shares, Class "B" shares, Class "C" shares, Class "D" shares, Class
"E" shares, Class "F" shares and Class "G" shares are as follows:

1.    The holders of the Class "A" shares shall be entitled to one (1) vote for
      each share held by them at all meetings of shareholders except meetings at
      which only holders of a specified class of shares, other than the Class
      "A" shares, are entitled to vote, and they shall be entitled to notice of
      all meetings of shareholders of the Corporation.

2.    Except as otherwise specifically provided in the Canada Business
      Corporations Act, the Class "B" shares shall not carry any right to vote
      nor shall the holders thereof be entitled to notice of or to attend
      shareholders' meetings.

3.    The Class "A" shares and Class "B" shares shall, subject to the rights of
      the Class "C" shares, Class "D" shares, Class "E" shares, Class "F" shares
      and Class "G" shares, be entitled at all times and from time to time, in
      the sole, absolute and unfettered discretion of the directors, to an
      unfixed non-cumulative dividend in any amount. Each Class "A" share and
      Class "B" share shall rank pari passu with respect to any such dividend.

4.    The Class "A" shares and the Class "B" shares shall rank pari passu in
      every other respect, and the holders of such Class "A" shares and Class
      "B" shares, shall, subject to the rights of the holders of the Class "C"
      shares, Class "D" shares, Class "E" shares, Class "F" shares and Class "G"
      shares, be entitled to receive the remaining property of the Corporation
      upon a dissolution.

5.    For purposes of this Schedule 1 the term "Redemption Amount" shall mean:

      (a)   In the case of a Class "C" share, Class "D" share, Class "E" share
            and Class "F" share, an amount equal to the consideration for which
            each such share had been issued or in the event such share had been
            issued in consideration of property or past services, an amount
            equal to the fair equivalent of money that the Corporation would
            have received if such share had been issued for money, and

      (b)   In the case of a Class "G" share, an amount equal to $1.00.



6.    Each Class "C" share, Class "D" share, Class "E" share, Class "F" share
      and Class "G" share shall, in priority to the Class "A" shares and Class
      "B" shares, carry the right, in the discretion of the directors, to a
      fixed monthly non-cumulative preferential dividend in the case of the
      Class "C" shares, Class "D" shares, Class "E" shares and Class "F" shares
      in an amount equal to one-half (1/2) of one percent (1%) of the amount of
      the consideration for which each share had been issued or in the event
      such share had been issued in consideration of property or past services,
      in an amount equal to one-half (1/2) of one percent (1%) of the amount of
      the fair equivalent of money that the Corporation would have received if
      such share had been issued for money and in the case of the Class "G"
      shares, in an amount equal to one-half (1/2) of one cent.

7.    Each Class "C" share, Class "D" share, Class "E" share, Class "F" share
      and Class "G" share shall, in priority to the Class "A" shares and Class
      "B" shares, carry the right, in the event of the liquidation or winding-up
      of the Corporation, to repayment of an amount equal to the Redemption
      Amount.

8.    In the event that only part of the amount of the consideration received by
      the Corporation for any share issued by the Corporation is added to the
      stated capital account for the class or series of shares of which such
      share forms part, such share shall be deemed to have been issued for the
      full amount of the consideration received therefor for all purposes other
      than stated capital but including dividends, redemptions, purchases,
      liquidation and dissolution. If shares of the Corporation are issued in
      payment of a dividend, the declared amount of the dividend stated as an
      amount of money shall be added to the stated capital account maintained
      for the shares of the class or seises issued in payment of the dividend
      and such shares shall be deemed to be issued for a consideration equal to
      the declared amount of such dividend.

9.    The Class "C" shares, Class "D" shares, Class "E" shares, Class "F" shares
      and Class "G" shares shall not carry the right to any further
      participation in profits or assets.

10.   The holders of the Class "C" shares and Class "E" shares shall be entitled
      to one (1) vote for each share held by them at all meetings of
      shareholders except meetings at which only holders of a specified class of
      shares, other than the Class "C" shares and Class "E" shares are entitled
      to vote, and they shall be entitled to notice of all meetings of
      shareholders of the Corporation.

11.   Except as otherwise specifically provided in the Canada Business
      Corporations Act, the Class "D" shares, the Class "F" shares and the Class
      "G" shares shall not carry any right to vote nor shall the holders thereof
      be entitled to notice of or to attend shareholders' meetings.

12.   Each Class "C" share, Class "D" share, Class "E" share, Class "F" share
      and Class "G" share shall be redeemable, at the option of the Corporation,
      for a price equal to the Redemption Amount. The Corporation may redeem all
      or any part of

                                       2


      the Class "C" shares, Class "D" shares, Class "E" shares, Class "F" shares
      or Class "G" shares, at any time at the option of the directors of the
      Corporation upon a notice of seven (7) days without the consent of the
      holders thereof, and if less than the whole amount of the then outstanding
      Class "C" shares, Class "D" shares, Class "E" shares, Class "F" shares or
      Class "G" shares shall be so redeemed, the shares to be redeemed shall be
      selected pro rata, by lot or in any other manner as the directors may
      determine.

13.   Each Class "E" share, Class "F" share and Class "G" share shall be
      redeemable, at the option of the holder of such share for a price equal to
      the Redemption Amount.

14.   The Class "C" shares, Class "D" shares, Class "E" shares, Class "F" shares
      and Class "G" shares shall rank pari passu in every other respect.
