          exercise any of the rights of the holders thereof, except the right to
          receive the Redemption Price, unless payment of the Redemption Price

          shall remain unaffected.  On or before the date specified for
          redemption, the Corporation shall have the right to deposit the
          Redemption Price of the Preferred Shares called for redemption in a
          special account with any chartered bank or trust company in Canada

<PAGE>

                                     -23-

          made or upon the date specified for redemption, whichever is later,
          the Preferred Shares in respect whereof such deposit shall have been
          made, shall be deemed to be redeemed and the rights of the respective
          holders thereof, after such deposit or after such redemption date, as
          the case may be, shall be limited to receiving, out of the moneys so
          deposited, without interest, the Redemption Price applicable to their
          respective Preferred Shares, the whole against presentation and
          surrender of the certificates representing such Preferred Shares. If
          less than all of the Preferred Shares are to be redeemed, the shares
          to be redeemed shall be redeemed pro rata, disregarding fractions,
          unless the holders of the Preferred Shares unanimously agree to the
          adoption of another method of selection of the Preferred Shares to be
          redeemed. If less than all of the Preferred Shares represented by any
          certificate be redeemed, a new certificate for the balance shall be
          issued.

     (f)  [At any time after ., 2006,] a holder of Preferred Shares shall be
          entitled to require the Corporation to redeem at any time all, or from
          time to time any part, of the Preferred Shares registered in the name
          of such holder by tendering to the Corporation, at its registered
          office, the share certificate(s) representing the Preferred Shares
          which the registered holder desires to have the Corporation redeem,
          which share certificate(s) shall be accompanied by a request in
          writing specifying (i) the number of Preferred Shares which the
          registered holder desires to have redeemed by the Corporation and (ii)
          the business day (in this paragraph referred to as the "Redemption
          Date") on which the holder desires to have the Corporation redeem such
          Preferred Shares, which Redemption Date shall not be less than five
          (5) days after the day on which the said request in writing is given
          to the Corporation. Upon receipt of the share certificate(s)
          representing the Preferred Shares which the registered holder desires
          to have the Corporation redeem, together with the said written
          request, the Corporation shall on, or at its option, before, the
          Redemption Date redeem such Preferred Shares by paying to the
          registered holder thereof, for each share to be redeemed, an amount
          equal to the Redemption Price in respect thereof.  Such payment shall
          be made by cheque payable at par at any branch of the Corporation's
          bankers for the time being in Canada.  The said Preferred Shares shall
          be deemed to be redeemed on the date of payment of the Redemption
          Price and, from and after such date, such Preferred Shares shall cease
          to be entitled to dividends and the holders thereof shall not be
          entitled to exercise any of the rights of the holders of Preferred
          Shares in respect thereof. Notwithstanding the foregoing, the
          Corporation shall only be obliged to redeem Preferred Shares so
          tendered for redemption to the extent that such redemption would not
          be contrary to any applicable law, and if such redemption of any such
          Preferred Shares would be contrary to any applicable law, the
          Corporation shall only be obliged to redeem such Preferred Shares to
          the extent that the moneys applied thereto shall be equal to such
          amount (rounded to the next lower multiple of one hundred dollars
          ($100.00)) as would not be contrary to such law, in which case the
          Corporation shall pay to each holder his pro rata share of the
          purchase moneys so allocated. If less than all the Preferred Shares
          represented by any certificate be redeemed, a new certificate for the
          balance shall be issued.
<PAGE>

                                     -24-

     (g)  The Corporation may purchase for cancellation or otherwise at any time
          all, or from time to time any part, of the Preferred Shares
          outstanding, by private contract at any price, with the unanimous
          consent of the holders of the Preferred Shares then outstanding, or by
          invitation for tenders addressed to all the holders of the Preferred
          Shares at the lowest price at which, in the opinion of the directors,
          each such share is obtainable but in no case shall the price for each
          such preferred share exceed the Redemption Price thereof. If less than
          all the Preferred Shares represented by any certificate are purchased
          by the Corporation, a new certificate for the balance shall be issued.

     (h)  For the purposes of the foregoing paragraphs II. (b), (c) and (d), the
          "Preferred Redemption Price" of each Preferred Share shall be an
          amount equal to the product of the fair market value of one (1) share
          of the common stock of Sun Microsystems, Inc. (a "Sun Share") at the
          time such Preferred Share is issued multiplied by the Share Exchange
          Ratio, as that term is defined in the acquisition agreement dated on
          or about June 19, 2001 by and among, inter alia, the Corporation, Sun
          Microsystems, Inc., 514713 N.B. Inc. and 3055855 Nova Scotia Company.
          For purposes of this paragraph II. (h), the fair market value of a Sun
          Share shall be the average closing sale price of one such Sun Share as
          reported on the NASDAQ National Market for the ten (10) consecutive
          days ending on the day that is immediately before the date on which
          such Preferred Share is issued to the holder thereof.

     (i)  In the event that only part of the amount of the consideration
          received by the Corporation for any Preferred Share issued by the
          Corporation is added to the stated capital account of the Preferred
          Shares, such Preferred Share shall be deemed to have been issued for
          the full amount of the consideration received, for all purposes of
          these articles (except only with respect to the stated capital of such
          Preferred Shares), including, but without limiting the generality of
          the foregoing, dividend rights, redemption rights and rights upon
          liquidation and dissolution.

     (j)  No change to any of the provisions of paragraphs II. (a) to (i) or of
          this paragraph (j) shall have any force or effect until it has been
          approved by a majority of not less than two-thirds () of the votes
          cast by the holders of the Preferred Shares, voting separately as a
          class at a meeting of such holders specially called for that purpose,
          or by a resolution in writing signed by all the holders of the
          Preferred Shares, in addition to any other approval required by the
          Business Corporations Act (Ontario).
