          (b)  The holders of the special shares shall in each fiscal year of
               the Corporation in the discretion of the directors, but always in
               preference and priority to any payment of dividends on the common
               shares for such fiscal year, be entitled to non-cumulative
               dividends in the amount of 8% per annum of the redemption price;
               if in any fiscal year, after providing for the full dividend on
               the special shares, there shall remain any profits or surplus
               available for dividends, such profits or surplus, or any part
               thereof, may, in the discretion of the directors, be applied to
               dividends on the common shares; the holders of the special shares
               shall not be entitled to any dividends other than or in excess of
               the non-cumulative dividends in the amount hereinbefore provided
               for.

          (c)  The Corporation may, at its option, redeem all or from time to
               time any part of the outstanding special shares on payment to the
               holders thereof, for each share to be redeemed, of the sum of
               $1.00 per share, together with all dividends declared thereon and
               unpaid. Before redeeming any special shares the Corporation shall
               mail to each person who, at the date of such mailing, is a
               registered holder of shares to be redeemed, notice of the
               intention of the Corporation to redeem such shares held by such
               registered holder; such notice shall be mailed by ordinary
               prepaid post addressed to the last address of such holder as it
               appears on the records of the Corporation or, in the event of the
               address of any such holder not appearing on the records of the
               Corporation, then to the last known address of such holder, at
               least 30 days before the date specified for redemption; such
               notice shall set out the date on which redemption is to take
               place and, if part only of the shares held by the person to whom
               it is addressed is to be redeemed, the number thereof so to be
               redeemed; on or after the date so specified for redemption the
               Corporation shall pay or cause to be paid the redemption price to
               the registered holders of the shares to be redeemed, on
               presentation and surrender of the certificates for the shares so
               called for redemption at such place or places as may be specified
               in such notice, and the certificates for such shares shall
               thereupon be cancelled, and the shares 
   6


                                     - 5 -


               represented thereby shall thereupon be redeemed. In case a part
               only of the outstanding special shares is at any time to be
               redeemed, the shares to be redeemed shall be selected, at the
               option of the directors, either by lot in such manner as the
               directors in their sole discretion shall determine or as nearly
               as may be pro rata (disregarding fractions) according to the
               number of special shares held by each holder. In case a part
               only of the special shares represented by any certificate shall
               be redeemed, a new certificate for the balance shall be issued
               at the expense of the Corporation. From and after the date
               specified for redemption in such notice, the holders of the
               shares called for redemption shall cease to be entitled to
               dividends and shall not be entitled to any rights in respect
               thereof, except to receive the redemption price, unless payment
               of the redemption price shall not be made by the Corporation in
               accordance with the foregoing provisions, in which case the
               rights of the holders of such shares shall remain unimpaired. On
               or before the date specified for redemption the Corporation
               shall have the right to deposit the redemption price of the
               shares called for redemption in a special account with any
               chartered bank or trust company in Canada named in the notice of
               redemption, such redemption price to be paid to or to the order
               of the respective holders of such shares called for redemption
               upon presentation and surrender of the certificates representing
               the same and, upon such deposit being made, the shares in
               respect whereof such deposit shall have been made shall be
               redeemed and the rights of the several holders thereof, after
               such deposit, shall be limited to receiving, out of the moneys so
               deposited, without interest, the redemption price applicable to
               their respective shares against presentation and surrender of
               the certificates representing such shares.

          (d)  (i)  Subject to paragraph 8(d)(ii) below, a holder of special
                    shares shall be entitled to require the Corporation to
                    redeem at any time and from time to time after the date of
                    issue of any special shares, upon giving notice as
                    hereinafter provided, all or any number of the special
                    shares registered in the name of such holder on the books of
                    the

                                     - 6 -

                    Corporation at a redemption price per share of $1.00
                    together with all dividends declared thereon and unpaid. A
                    holder of special shares exercising his option to have the
                    Corporation redeem, shall give notice to the Corporation,
                    which notice shall set out the date on which the Corporation
                    is to redeem, which date shall not be less than 10 days nor
                    more than 30 days from the date of mailing of the notice,
                    and if the holder desires to have less than all of the
                    special shares registered in his name redeemed by the
                    Corporation, the number of the holder's shares to be
                    redeemed. The date on which the redemption at the option of
                    the holder is to occur is hereafter referred to as the
                    "option redemption date". The holder of any special shares
                    may, with the consent of the Corporation, revoke such notice
                    prior to the option redemption date. Upon delivery to the
                    Corporation of a share certificate or certificates
                    representing the special shares which the holder desires to
                    have the Corporation redeem, the Corporation shall, on the
                    option redemption date, redeem such special shares by paying
                    to the holder the redemption price therefor. Upon payment of
                    the redemption price of the special shares to be redeemed by
                    the Corporation, the holders thereof shall cease to be
                    entitled to dividends or to exercise any rights of holders
                    in respect thereof.

               (ii) If the redemption by the Corporation on any option
                    redemption date of all of the special shares to be redeemed
                    on such date would be contrary to any provisions of the Act
                    or any other applicable law, the Corporation shall be
                    obligated to redeem only the maximum number of special
                    shares which the Corporation determines it is then permitted
                    to redeem, such redemptions to be made pro rata
                    (disregarding fractions of shares) according to the number
                    of special shares required by each such holder to be
                    redeemed by the Corporation and the Corporation shall issue
                    new certificates representing the special shares not
                    redeemed by the Corporation; the Corporation shall, before
                    redeeming any

                                     - 7 -

                    other special shares, redeem in the manner contemplated by
                    paragraph 8(c) on the 1st day of each month thereafter the
                    maximum number of such special shares as would not then be
                    contrary to any provisions of the Act or any other
                    applicable law, until all of such shares have been redeemed,
                    provided that the Corporation shall be under no obligation
                    to give any notice to the holders of the special shares in
                    respect of such redemption or redemptions as provided for in
                    paragraph 8(c).

          (e)  The Corporation may purchase for cancellation the whole or any
               part of the special shares at the lowest price at which, in the
               opinion of the directors, such shares are obtainable, but not
               exceeding the sum of $1.00 per share, together with all dividends
               declared thereon and unpaid.

          (f)  In the event of the liquidation, dissolution or winding-up of the
               Corporation, whether voluntary or involuntary, the holders of the
               special shares shall be entitled to receive, before any
               distribution of any part of the assets of the Corporation among
               the holders of any other shares, for each special share, an
               amount of $1.00 per share and any dividends declared thereon and
               unpaid and no more.

          (g)  The holders of the common shares shall be entitled to receive
               notice of and to attend and vote at all meetings of the
               shareholders of the Corporation (except where the holders of a
               specified class are entitled to vote separately as a class as
               provided in the Act) and each common share shall confer the right
               to 1 vote in person or by proxy at all meetings of shareholders
               of the Corporation.

          (h)  Subject to the prior rights of the holders of the special
               shares, in the event of the liquidation, dissolution or
               winding-up of the Corporation, whether voluntary or involuntary,
               the holders of the common shares shall be entitled to receive the
               remaining property of the Corporation.
