          will be reduced by such number of Exchangeable Shares equal to the
          outstanding principal plus accrued interest of such Shareholders loans
          as of the Closing Date divided by the Trading Price, and if required,
          by an amount of cash payable to such Exchanging Shareholder equal to

          Exchanging Shareholders loans as of the Closing Date; and

     (b)  the amount of cash payable to a Tendering Shareholder will be reduced
          by an amount equal to the outstanding principal plus accrued interest
          of such Tendering Shareholders loans as of the Closing Date.

     Effective upon Closing, each Company Option will be exchanged and converted
by Parent into a Parent Option.  Each Company Option so exchanged and converted
by Parent pursuant to this Section 2.7 will continue to have, and be subject to,
the same terms and conditions (subject to any waivers of acceleration of
vesting, including vesting terms) set forth in the Plan, and the option
agreements relating thereto, as in effect immediately prior to the Closing,
except that (i) such assumed Company Option will be exercisable for that number
of whole shares of Parent Common Stock equal to the product of the number of
Company Shares that were issuable upon exercise of such Company Option
immediately prior to the Closing multiplied by the Option Exchange Ratio,
rounded down to the nearest whole number of shares of Parent Common Stock, and
(ii) the per share exercise price for the shares of Parent Common Stock issuable
upon exercise of such assumed Company Option will be equal to the quotient
obtained by dividing the exercise price per share of Company Shares at which
such assumed Company Option was exercisable immediately prior to the Closing
Date by the Option Exchange Ratio, rounded up to the nearest whole cent.  No
Company Option will be exercisable until the registration statement on Form S-8
described in the Acquisition Agreement is effective.

               Escrowed Cash required to be escrowed by such Securityholder);

     and the certificates representing the Company Shares so surrendered shall
     be cancelled; and

condition precedent to the payment of the said consideration, require the owner
of such lost, stolen or destroyed certificates to deliver a bond in such sum as
it may direct against any claim that may be made against ExchangeCo or CallCo,
as the case may be, with respect to the certificates alleged to have been lost,
stolen or destroyed.

                 of the amount, if any, by which such Debentureholder Cash
                 Payment exceeds the certificate limit;

          (iv)   if a certificate is not so delivered at or prior to Closing,
                 CallCo shall be entitled to withhold twenty-five percent (25%)

          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)

          to be entitled to dividends and the holders thereof shall not be
          entitled to exercise any of the rights of the holders of Preferred

          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.

     (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).
