                        the Exchange Ratio, rounded up to the nearest whole
                        cent. Consistent with the terms of the relevant
                        Pixstream Stock Option Plan and the documents governing
                        the outstanding options under such plan, as modified by
                        the Waiver, the transaction contemplated hereby will not
                        terminate any of the outstanding options under the
                        relevant Pixstream Stock Option Plan or accelerate the
                        exercisability or vesting of such options or the Cisco
                        Common Shares which will be subject to those options

                        immediately prior to the Effective Time to repurchase
                        unvested Pixstream Common Shares (the "Repurchase
                        Options") shall be assigned to Cisco and shall
                        thereafter be exercisable by Cisco upon the same terms
                        and conditions in effect immediately prior to the
                        Effective Time, except that the shares

                        purchasable pursuant to the Repurchase Options and the
                        purchase price per share shall be adjusted in the manner
                        set forth in Section 2.2(f)(i) above to reflect the
                        Exchange Ratio and the U.S. Dollar/Canadian Dollar Noon
                        Spot Rate exchange rate effective as of 12:00 p.m.
                        Eastern Standard Time on the Effective Date as reported
                        by the Bank of Canada;

                (iii)   each outstanding U.K. Option shall be exchanged by Cisco
                        for an option to acquire Cisco Common Shares as set
                        forth below, provided the holder of each such option has
                        consented to such exchange and Cisco has received U.K.
                        Inland Revenue approval for such exchanged option to
                        continue to be treated as an approved option under
                        Schedule 9 of the U.K. Income and Corporation Taxes Act
                        1988. Each such option so exchanged by Cisco under this
                        Agreement shall continue to have, and be subject to, the
                        same terms and conditions set forth in the U.K. Plan and
                        the applicable stock option agreements, immediately
                        prior to the Effective Time, except that (i) such option
                        will be exercisable for that number of whole Cisco
                        Common Shares equal to the product of the number of
                        Pixstream Common Shares that were issuable upon exercise
                        of such option immediately prior to the Effective Time
                        multiplied by the Exchange Ratio and rounded down to the
                        nearest whole number of Cisco Common Shares, and (ii)
                        the per share exercise price for the Cisco Common Shares
                        issuable upon exercise of such exchanged option will be
                        equal to the quotient determined by dividing the
                        exercise price per Pixstream Common Share at which such
                        option was exercisable immediately prior to the
                        Effective Time (adjusted for the U.S. Dollar/Canadian
                        Dollar Noon Spot Rate exchange rate effective as of

                        Ratio, rounded up to the nearest whole cent. Consistent
                        with the terms of the U.K. Plan and the documents
                        governing the outstanding options under such Plan, the
                        transaction contemplated hereby will not terminate any
                        of the outstanding options under the U.K. Plan or
                        accelerate the exercisability or vesting of such options
                        or the Cisco Common Shares which will be subject to
                        those options upon Cisco's exchange of the options at
                        the Effective Time. In the event U.K. Inland Revenue
                        approval is not obtained, then the U.K. Options shall be
                        assumed by Cisco as provided in Section 2.2(f)(i) above.
                        [NOTE: SECTION 2.2(f)(ii) MAY NEED MODIFICATION AT THE
                        TIME OF FILING ARTICLES OF ARRANGEMENT TO REFLECT
                        WHETHER OR NOT U.K. INLAND REVENUE APPROVAL HAS BEEN
                        OBTAINED]

        (g)     Subject to adjustment in accordance with section 2.3 hereof, the
                "Exchange Ratio" shall equal the ratio of (x) a quotient, the
                numerator of which is $361.295 million less the amount of any
                Pixstream Expenses less $5.22 times the difference between
                1,140,000 and the number of Pixstream Options granted between
                the date hereof and the Effective Time, and the denominator of
                which is the Effective Cisco Price and (y) the total number of
                Pixstream Common Shares issued and outstanding on a fully
                diluted basis at the Effective Time (after giving effect to the
                conversion, exchange or exercise, as the case may be, of all
                securities convertible

                Shares, including all unexpired and unexercised outstanding
                options, warrants or other rights to acquire Pixstream Common
                Shares assumed or exchanged by the Cisco Parties).

                The "Effective Cisco Price" shall equal the average of the
                closing prices of Cisco Common Shares as quoted on Nasdaq for
                the ten (10) consecutive trading days ending on the third
                trading day prior to the Effective Date.

                [NOTE: THE EXCHANGE RATIO AS DETERMINED BY CISCO AND PIXSTREAM
                IN ACCORDANCE WITH THE FOREGOING SHALL BE SET FORTH IN THE
                ARTICLES OF ARRANGEMENT.]

        (h)     Amalco shall be authorized to continue under the laws of the
                Province of Nova Scotia and apply pursuant to the Companies Act
                of Nova Scotia for a certificate of continuance continuing
                Amalco as a body corporate under that Act [NOTE: IF NECESSARY,
                THE PLAN OF ARRANGEMENT WILL INCLUDE AS APPENDICES THE FORM OF
                THE MEMORANDUM OF ASSOCIATION AND ARTICLES OF ASSOCIATION AND
                ANY OTHER PROVISIONS REQUIRED BY THE REGISTRAR OF JOINT STOCK
                COMPANIES OF NOVA SCOTIA TO GIVE APPROVAL TO THE CHANGE IN
                JURISDICTION.]

2.3     ADJUSTMENT TO EXCHANGE RATIO

        The Exchange Ratio shall be adjusted to reflect fully the effect of any
stock split, reverse split, stock dividend (including any dividend or
distribution of securities convertible into Cisco Common Shares or Pixstream
capital stock), reorganization, recapitalization or other like change with
respect to Cisco Common Shares or Pixstream capital stock occurring after the
date hereof and prior to the Effective Time, so as to provide the parties the
same economic effect as contemplated by this Plan of Arrangement prior to such
stock split, reverse split, stock dividend, reorganization, recapitalization, or
other like change. No other adjustment shall be made in the number of Cisco
Common Shares or Exchangeable Shares issuable hereunder as a result of (x) any
increase or decrease in the market price of Cisco Common Shares prior to the
Effective Time, or (y) any cash proceeds received by Pixstream from the date
hereof to the Effective Time pursuant to the exercise of currently outstanding
Pixstream Options or Pixstream Warrants.

2.4     TAX ELECTIONS

        Holders of common shares of Amalco shall be entitled to make an income
tax election pursuant to subsection 85(1) or 85(2) of the ITA (or the analogous
provisions of provincial income tax law) with respect to the transfer of their
common shares of Amalco to Cisco Exchangeco by providing two signed copies of
the necessary prescribed election forms to the Depositary within 90 days
following the Effective Date, duly completed with the details of the number of
common shares of Amalco transferred and the applicable agreed upon amounts for
the purposes of such elections. Thereafter, subject to the election forms
complying with the provisions of the ITA (or applicable provincial income tax
law), the forms shall be signed by Cisco Exchangeco (within 30 days of the
receipt thereof by Cisco Exchangeco) and promptly returned to such holders of
common shares of Amalco by ordinary mail for filing with the Canada Customs and
Revenue Agency (or the applicable provincial taxing authority).

                                RIGHTS OF DISSENT

3.1     RIGHTS OF DISSENT

        Holders of Pixstream Common Shares may exercise rights of dissent
("Dissent Rights") with respect to such shares pursuant to and in the manner set
forth in section 190 of the CBCA and this section 3.1 (the "Dissent Procedures")
in connection with the Arrangement, provided that, notwithstanding subsection
190(5) of the CBCA, the written objection to the Arrangement Resolution referred
to in subsection 190(5) of the CBCA must be received by Pixstream not later than
5:00 p.m. (Toronto time) on the Business Day preceding the Pixstream Meeting.
Holders of Pixstream Common Shares who duly exercise such rights of dissent and
who:

        (a)     are ultimately entitled to be paid fair value for their
                Pixstream Common Shares shall be deemed to have transferred such
                Pixstream Common Shares to Pixstream immediately prior to the
                Effective Time, without any further act or formality and free
                and clear of all liens, claims and encumbrances and such shares
                shall be cancelled as of the Effective Time; or

        (b)     are ultimately not entitled, for any reason, to be paid fair
                value for their Pixstream Common Shares shall be deemed to have
                participated in the Arrangement on the same basis as a
                non-dissenting holder of Pixstream Common Shares and shall
                receive Exchangeable Shares of Cisco Exchangeco on the basis
                determined in accordance with section 2.2;

but in no case shall Cisco, Cisco Exchangeco, Cisco Newco, Pixstream or any
other Person be required to recognize such holders as holders of Pixstream
Common Shares after the Effective Time, and the names of such holders of
Pixstream Common Shares shall be deleted from the register of holders of
Pixstream Common Shares at the Effective Time. Each of Pixstream and the Cisco
Parties shall cause any payments to be made to the Dissenting Shareholders to be
made by Pixstream using Pixstream's assets. The Cisco Parties will not directly
or indirectly provide any funds for the purposes of making payments to
Dissenting Shareholders.

                       CERTIFICATES AND FRACTIONAL SHARES

4.1     ISSUANCE OF CERTIFICATES REPRESENTING EXCHANGEABLE SHARES

        At or promptly after the Effective Time, Cisco Exchangeco shall deposit
with the Depositary, for the benefit of the holders of Pixstream Common Shares
and Holdco Common Shares who will receive Exchangeable Shares in connection with
the Arrangement, certificates representing the Exchangeable Shares issued
pursuant to section 2.2. Upon surrender to the Depositary for cancellation of a
certificate which immediately prior to the Effective Time represented one or
more Pixstream Common Shares or Holdco Common Shares that were converted into
common shares of Amalco and then exchanged for one or more Exchangeable Shares
under the Arrangement or which represented one or more Pixstream Warrants that
were exercised into Pixstream Common Shares prior to the Arrangement and for
which certificates



                                       11
<PAGE>   12

representing Pixstream Common Shares have not been issued, together with such
other documents and instruments as would have been required to effect the
transfer of the shares formerly represented by such certificate under the CBCA
and the by-laws of Pixstream or Holdco, as the case maybe, and such additional
documents and instruments as the Depositary may reasonably require, the holder
of such surrendered certificate shall be entitled to receive in exchange
therefor, and the Depositary shall deliver to such holder, a certificate
representing that number (rounded down to the nearest whole number) of
Exchangeable Shares which such holder has the right to receive (together with
any dividends or distributions with respect thereto pursuant to section 4.2 and
any cash in lieu of fractional Exchangeable Shares pursuant to section 4.3), and
the certificate so surrendered shall forthwith be cancelled. In the event of a
transfer of ownership of Pixstream Common Shares or Holdco Common Shares that is
not registered in the transfer records of Pixstream or Holdco, as the case
maybe, a certificate representing the proper number of Exchangeable Shares may
be issued to the transferee if the certificate representing such Pixstream
Common Shares or Holdco Common Shares is presented to the Depositary,
accompanied by all documents required to evidence and effect such transfer.
Until surrendered as contemplated by this section 4.1, each certificate which
immediately prior to the Effective Time represented Pixstream Common Shares or
Holdco Common Shares that were converted into common shares of Amalco and were
then exchanged for Exchangeable Shares (or, as described above, that represented
Pixstream Warrants that were exercised into Pixstream Common Shares) shall be
deemed at all times after the Effective Time to represent only the right to
receive upon such surrender (i) the certificate representing Exchangeable Shares
as contemplated by this section 4.1, (ii) a cash payment in lieu of any
fractional Exchangeable Shares as contemplated by section 4.3, and (iii) any
dividends or distributions with a record date after the Effective Time
theretofore paid or payable with respect to Exchangeable Shares as contemplated
by section 4.2. The rights of the holders of the Pixstream Common Shares and
Holdco Common Shares to receive certificates representing Exchangeable Shares
shall be subject to Article VIII of the Merger Agreement.

4.2     DISTRIBUTIONS WITH RESPECT TO UNSURRENDERED CERTIFICATES

     No dividends or other distributions declared or made after the Effective
Time with respect to Exchangeable Shares with a record date after the Effective
Time shall be paid to the holder of any unsurrendered certificate which
immediately prior to the Effective Time represented outstanding Pixstream Common
Shares or Holdco Common Shares that were converted, transferred and exchanged
pursuant to section 2.2 (or, as applicable, representing Pixstream Warrants as
described in Section 4.1), and no cash payment in lieu of fractional shares
shall be paid to any such holder pursuant to section 4.3, unless and until the
holder of record of such certificate shall surrender such certificate in
accordance with section 4.1. Subject to applicable law, there shall be paid to
the record holder of the certificates representing Pixstream Common Shares or
Holdco Common Shares (or, as applicable, representing Pixstream Warrants as
described in Section 4.1), without interest, (i) at the time of such surrender
of any such certificate, the amount of any cash payable in lieu of a fractional
Exchangeable Share to which such holder is entitled pursuant to section 4.3,
(ii) at the time of such surrender of any such certificate, the amount of
dividends or other distributions with a record date after the Effective Time
theretofore paid with respect to whole Exchangeable Shares, to which such holder
is entitled and (iii) on the appropriate payment date, the amount of dividends
or other distributions




                                       12
<PAGE>   13

with a record date after the Effective Time but prior to surrender and a payment
date subsequent to surrender payable with respect to whole Exchangeable Shares.

4.3     FRACTIONAL SHARES

        No certificates or scrip representing fractional Exchangeable Shares
shall be issued upon the surrender for exchange of certificates pursuant to
section 4.1 and no dividend, stock split or other change in the capital
structure of Cisco Exchangeco or Cisco shall relate to any such fractional
security and such fractional interests shall not entitle the owner thereof to
exercise any rights as a security holder of Cisco Exchangeco or Cisco. In lieu
of any such fractional securities, each Person otherwise entitled to a
fractional interest in an Exchangeable Share will receive the cash payment from
the Depositary as provided in Section 2.2 hereof. As soon as possible after the
Effective Time, Cisco Exchangeco shall deposit with the Depositary such amounts
of cash as may be required to pay for such fractional interests of Exchangeable
Shares.

4.4     LOST CERTIFICATES

        In the event any certificate which immediately prior to the Effective
Time represented one or more outstanding Pixstream Common Shares or Holdco
Common Shares that were converted, transferred and exchanged pursuant to section
2.2 (or, as applicable, that represented Pixstream Warrants as described in
Section 4.1), shall have been lost, stolen or destroyed, upon the making of an
affidavit of that fact by the Person claiming such certificate to be lost,
stolen or destroyed, the Depositary will issue in exchange for such lost, stolen
or destroyed certificate, one or more certificates representing one or more
Exchangeable Shares (and any dividends or distributions with respect thereto and
any cash pursuant to section 4.3) in accordance with the foregoing provisions of
this Article 4. When authorizing such payment in exchange for any lost, stolen
or destroyed certificate, the Person to whom certificates representing
Exchangeable Shares are to be issued shall, as a condition precedent to the
issuance thereof, give a bond satisfactory to Cisco Exchangeco, Cisco and their
respective transfer agents in such sum as Cisco Exchangeco or Cisco may direct
or otherwise indemnify Cisco Exchangeco and Cisco in a manner satisfactory to
Cisco Exchangeco and Cisco against any claim that may be made against Cisco
Exchangeco or Cisco with respect to the certificate alleged to have been lost,
stolen or destroyed.

4.5     EXTINCTION OF RIGHTS

        Any certificate which immediately prior to the Effective Time
represented outstanding Pixstream Common Shares or Holdco Common Shares that
were converted, transferred and exchanged pursuant to section 2.2 (or, as
applicable, that represented Pixstream Warrants as described in Section 4.1),
and not deposited, with all other instruments required by section 4.1 on or
prior to the sixth anniversary of the Effective Date shall cease to represent a
claim or interest of any kind or nature as a shareholder of Cisco Exchangeco or
Cisco. On such date, the Exchangeable Shares (or cash in lieu of fractional
interests therein, as provided in section 4.3) to which the former registered
holder of the certificate referred to in the preceding sentence was ultimately
entitled shall be deemed to have been surrendered to Cisco Exchangeco or Cisco,
as the case may be, together with all entitlements to dividends, distributions
and interest thereon held for such former registered holder.

4.6     WITHHOLDING RIGHTS

        Cisco Exchangeco, Cisco Newco, Cisco and the Depositary shall be
entitled to deduct and withhold from any dividend or consideration otherwise
payable to any holder of Pixstream Common Shares, Holdco Common Shares, Cisco
Common Shares or Exchangeable Shares such amounts as Pixstream, Holdco, Cisco
Exchangeco, Cisco Newco, Cisco or the Depositary are required or permitted to
deduct and withhold with respect to such payment under the ITA, the United
States Internal Revenue Code of 1986 or any provision of provincial, state,
local or foreign tax law, in each case, as amended or would be permitted to
withhold if an equal amount were remitted to the appropriate taxing authority.
To the extent that amounts are so withheld, such withheld amounts shall be
treated for all purposes hereof as having been paid to the holder of the shares
in respect of which such deduction and withholding was made, provided that such
withheld amounts (or equivalent amounts, if applicable) are actually remitted to
the appropriate taxing authority. To the extent that the amount so required or
permitted or which would be permitted to be deducted or withheld from any
payment to a holder exceeds the cash portion of the consideration otherwise
payable to the holder, Cisco Exchangeco, Cisco Newco, Cisco and the Depositary
are hereby authorized to sell or otherwise dispose of such portion of the
consideration as is necessary to provide sufficient funds to Cisco Exchangeco,
Cisco Newco, Cisco or the Depositary, as the case may be, to enable it to comply
with such deduction or withholding requirement and Cisco Exchangeco, Cisco
Newco, Cisco or the Depositary shall notify the holder thereof and remit any
unapplied balance of the net proceeds of such sale.


                                    ARTICLE 5
          CERTAIN RIGHTS OF CISCO NEWCO TO ACQUIRE EXCHANGEABLE SHARES

5.1     CISCO NEWCO LIQUIDATION CALL RIGHT

        (a)     Cisco Newco shall have the overriding right (the "Liquidation
                Call Right"), in the event of and notwithstanding the proposed
                liquidation, dissolution or winding-up of Cisco Exchangeco or
                any other distribution of the assets of Cisco Exchangeco among
                its shareholders for the purpose of winding up its affairs
                pursuant to Article 5 of the Exchangeable Share Provisions, to
                purchase from all but not less than all of the holders of
                Exchangeable Shares (other than Cisco or any holder of
                Exchangeable Shares which is an affiliate of Cisco) on the
                effective date of such liquidation, dissolution, winding-up or
                other distribution (the "Liquidation Date") all but not less
                than all of the Exchangeable Shares held by each such holder on
                payment by Cisco Newco of an amount per Exchangeable Share (the
                "Liquidation Call Purchase Price") equal to the Current Market
                Price of a Cisco Common Share on the last Business Day prior to
                the Liquidation Date which shall be satisfied in full by Cisco
                Newco causing to be delivered to such holder one Cisco Common
                Share, plus, to the extent not paid by Cisco Exchangeco, an
                additional amount equivalent to the full amount of all declared
                and unpaid dividends on each such Exchangeable Share held by
                such holder on any dividend record date which occurred prior to
                the Liquidation Date (as used in this section, the "Dividend
                Amount"). In the event of the exercise of the Liquidation Call
                Right by Cisco Newco, each holder shall be obligated to sell all
                the Exchangeable Shares held by



                                       14

                the holder to Cisco Newco on the Liquidation Date on payment by
                Cisco Newco to the holder of the Liquidation Call Purchase Price
                for each such share, and Cisco Exchangeco shall have no
                obligation to pay any Liquidation Amount to the holders of such
                Exchangeable Shares so purchased by Cisco Newco.

        (b)     To exercise the Liquidation Call Right, Cisco Newco must notify
                Cisco Exchangeco's transfer agent (the "Transfer Agent"), as
                agent for the holders of Exchangeable Shares, and Cisco
                Exchangeco of Cisco Newco's intention to exercise such right at
                least 45 days before the Liquidation Date in the case of a
                voluntary liquidation, dissolution or winding-up of Cisco
                Exchangeco or any other voluntary distribution of the assets of
                Cisco Exchangeco among its shareholders for the purpose of
                winding up its affairs and at least five Business Days before
                the Liquidation Date in the case of an involuntary liquidation,
                dissolution or winding-up of Cisco Exchangeco or any other
                involuntary distribution of the assets of Cisco Exchangeco among
                its shareholders for purposes of winding up its affairs. The
                Transfer Agent will notify the holders of Exchangeable Shares as
                to whether or not Cisco Newco has exercised the Liquidation Call
                Right forthwith after the earlier of (i) receipt of notice by
                the Transfer Agent from Cisco Newco of its intention to exercise
                such right and (ii) the expiry of the period during which the
                same may be exercised by Cisco Newco. If Cisco Newco exercises
                the Liquidation Call Right, then on the Liquidation Date, Cisco
                Newco will purchase and the holders will sell all of the
                Exchangeable Shares then outstanding for a price per share equal
                to the Liquidation Call Purchase Price, which shall be satisfied
                as set out in paragraph 5.1(a) above.

        (c)     For the purposes of completing the purchase of the Exchangeable
                Shares pursuant to the Liquidation Call Right, Cisco Newco shall
                deposit with the Transfer Agent, on or before the Liquidation
                Date, certificates representing the aggregate number of Cisco
                Common Shares deliverable by Cisco Newco and a cheque or cheques
                of Cisco Newco payable at par at any branch of the bankers of
                Cisco Newco representing the aggregate Dividend Amount, if any,
                in payment of the total Liquidation Call Purchase Price, less
                any amounts withheld pursuant to section 4.6 hereof. Provided
                that Cisco Newco has complied with the immediately preceding
                sentence, on and after the Liquidation Date the rights of each
                holder of Exchangeable Shares will be limited to receiving,
                without interest, such holder's proportionate part of the total
                Liquidation Call Purchase Price payable by Cisco Newco upon
                presentation and surrender by the holder of certificates
                representing the Exchangeable Shares held by such holder and the
                holder shall on and after the Liquidation Date be considered and
                deemed for all purposes to be the holder of the Cisco Common
                Shares to which it is entitled. Upon surrender to the Transfer
                Agent of a certificate or certificates representing Exchangeable
                Shares, together with such other documents and instruments as
                may be required to effect a transfer of Exchangeable Shares
                under the laws applicable to Cisco Exchangeco and the by-laws of
                Cisco Exchangeco and such additional documents and instruments
                as the Transfer Agent may reasonably require, the holder of such
                surrendered certificate or certificates shall be entitled to
                receive in exchange therefor, and the

                which the holder is entitled and a cheque or cheques of Cisco
                Newco payable at par at any branch of the bankers of Cisco Newco
                in payment of any Dividend Amount less any amounts withheld
                pursuant to section 4.6 hereof. If Cisco Newco does not exercise
                the Liquidation Call Right in the manner described above, on the
                Liquidation Date the holders of the Exchangeable Shares will be
                entitled to receive in exchange therefor the Liquidation Amount
                otherwise payable by Cisco Exchangeco in connection with the
                liquidation, dissolution or winding-up of Cisco Exchangeco
                pursuant to Article 5 of the Exchangeable Share Provisions.

                the Exchangeable Share Provisions, to purchase from all but not
                less than all of the holders of Exchangeable Shares (other than
                Cisco or any holder of Exchangeable Shares which is an affiliate
                of Cisco ) on the Redemption Date all but not less than all of
                the Exchangeable Shares held by each such holder on payment by

                Market Price of an Cisco Common Share on the last Business Day
                prior to the Redemption Date, which shall be satisfied in full

                Common Share, plus, to the extent not paid by Cisco Exchangeco,
                an additional amount equivalent to the full amount of all
                declared and unpaid dividends on each such Exchangeable Share
                held by such holder on any dividend record date which occurred
                prior to the Redemption Date (as used in this section, the
                "Dividend Amount"). In the event of the exercise of the
                Redemption Call Right by Cisco Newco, each holder shall be
                obligated to sell all the Exchangeable Shares held by the holder
                to Cisco Newco on the Redemption Date on payment by Cisco Newco
                to the holder of the Redemption Call Purchase Price for each
                such Exchangeable Share, and Cisco Exchangeco shall have no
                obligation to redeem such Exchangeable Shares so purchased by
                Cisco Newco.

        (b)     To exercise the Redemption Call Right, Cisco Newco must notify
                the Transfer Agent, as agent for the holders of Exchangeable
                Shares, and Cisco Exchangeco of Cisco Newco's intention to
                exercise such right at least 60 days before the Redemption Date,
                except in the case of a redemption occurring as a result of an
                Cisco Control Transaction, an Exchangeable Share Voting Event or
                an Exempt Exchangeable Share Voting Event, in which case Cisco
                Newco shall so notify the Transfer Agent and Cisco Exchangeco on
                or before the Redemption Date. The Transfer Agent will notify
                the holders of the Exchangeable Shares as to whether or not
                Cisco Newco has exercised the Redemption Call Right forthwith
                after the earlier of (i) receipt of notice by the Transfer Agent
                from Cisco Newco of its intention to exercise such right and
                (ii) the expiry of the period during which the same may be
                exercised by Cisco Newco. If Cisco Newco exercises the



                                       16

                Redemption Call Right, on the Redemption Date Cisco Newco will
                purchase and the holders will sell all of the Exchangeable
                Shares then outstanding for a price per share equal to the
                Redemption Call Purchase Price, which shall be satisfied as set
                out in paragraph 5.2(a) above.

        (c)     For the purposes of completing the purchase of the Exchangeable
                Shares pursuant to the Redemption Call Right, Cisco Newco shall
                deposit with the Transfer Agent, on or before the Redemption
                Date, certificates representing the aggregate number of Cisco
                Common Shares deliverable by Cisco Newco upon exercise of such
                right and a cheque or cheques of Cisco Newco payable at par at
                any branch of the bankers of Cisco Newco representing the
                aggregate Dividend Amount, if any, in payment of the total
                Redemption Call Purchase Price, less any amounts withheld
                pursuant to section 4.6 hereof. Provided that Cisco Newco has
                complied with the immediately preceding sentence, on and after
                the Redemption Date the rights of each holder of Exchangeable
                Shares will be limited to receiving such holder's proportionate
                part of the total Redemption Call Purchase Price payable by
                Cisco Newco upon presentation and surrender by the holder of
                certificates representing the Exchangeable Shares held by such
                holder and the holder shall on and after the Redemption Date be
                considered and deemed for all purposes to be the holder of the
                Cisco Common Shares to which it is entitled. Upon surrender to
                the Transfer Agent of a certificate or certificates representing
                Exchangeable Shares, together with such other documents and
                instruments as may be required to effect a transfer of
                Exchangeable Shares under the laws applicable to Cisco
                Exchangeco and the by-laws of Cisco Exchangeco and such
                additional documents and instruments as the Transfer Agent may
                reasonably require, the holder of such surrendered certificate
                or certificates shall be entitled to receive in exchange
                therefor, and the Transfer Agent on behalf of Cisco Newco shall
                deliver to such holder, certificates representing the Cisco
                Common Shares to which the holder is entitled and a cheque or
                cheques of Cisco Newco payable at par at any branch of the
                bankers of Cisco Newco in payment of any Dividend Amount, less
                any amounts withheld pursuant to section 4.6 hereof. If Cisco
                Newco does not exercise the Redemption Call Right in the manner
                described above, on the Redemption Date the holders of the
                Exchangeable Shares will be entitled to receive in exchange
                therefor the redemption price otherwise payable by Cisco
                Exchangeco in connection with the redemption of the Exchangeable
                Shares pursuant to Article 7 of the Exchangeable Share
                Provisions.

                other capital reorganization or other transaction affecting the
                Exchangeable Shares), in which case the Board of Directors may
                accelerate such redemption date to such date prior to the fifth
                anniversary of the Effective Date as it may determine, upon at
                least 60 days' prior written notice to the registered holders of

        (b)     a Cisco Control Transaction occurs, in which case, provided that
                the Board of Directors determines, in good faith and in its sole

                Exchangeable Shares in connection with such Cisco Control
                Transaction and that the redemption of all but not less than all

                the completion of such Cisco Control Transaction in accordance
                with its terms, the Board of Directors may accelerate such

                days' prior written notice to the registered holders of the
                Exchangeable Shares as the Board of Directors may determine to
                be reasonably practicable in such circumstances;

        (c)     an Exchangeable Share Voting Event is proposed, in which case,
                provided that the Board of Directors has determined, in good
                faith and in its sole discretion, that it is not reasonably
                practicable to accomplish the business purpose intended by the
                Exchangeable Share Voting Event (which business purpose must be
                bona fide and not for the primary purpose of causing the
                occurrence of a Redemption Date), in any other commercially
                reasonable manner that does not result in an Exchangeable Share
                Voting Event, the Board of Directors may accelerate such
                redemption date to such date prior to the fifth anniversary of
                the Effective Date as it may determine and the Board of
                Directors shall give such number of days' prior written notice
                of such redemption to the registered holders of the Exchangeable
                Shares as the Board of Directors may determine to be reasonably
                practicable in such circumstances; or

                holders of the Exchangeable Shares fail to take the necessary
                action at a meeting or other vote of holders of Exchangeable
                Shares, to approve or disapprove, as applicable, the Exempt
                Exchangeable Share Voting Event, in which case the Board of
                Directors may accelerate such redemption date to such date prior
                to the fifth anniversary of the Effective Date as it may
                determine and the Board of Directors shall give such number of
                days' prior written notice of such redemption to the registered
                holders of the

                be reasonably practicable in such circumstances,

        notice of redemption under clauses (a), (b), (c) or (d) above to less
        than 10% of such holders of Exchangeable Shares shall not affect the
        validity of any such redemption.

                (b)     in the case of a stock dividend declared on the Cisco
                        Common Shares to be paid in Cisco Common Shares, in such
                        number of Exchangeable Shares for each Exchangeable
                        Share as is equal to the number of Cisco Common Shares
                        to be paid on each Cisco Common Share; or

                (c)     in the case of a dividend declared on the Cisco Common
                        Shares in property other than cash or Cisco Common
                        Shares, in such type and amount of property for each

        contemplated by section 3.1(a) hereof and the sending of such a cheque

        Common Shares.

3.4     If on any payment date for any dividends declared on the Exchangeable
        Shares under section 3.1 hereof the dividends are not paid in full on
        all of the Exchangeable Shares then outstanding, any such dividends that
        remain unpaid shall be paid on a subsequent date or dates determined by
        the Board of Directors on which the Corporation shall have sufficient
        moneys, assets or property properly applicable to the payment of such
        dividends.

3.5     The Board of Directors shall determine, in good faith and in its sole
        discretion, economic equivalence for the purposes of section 3.1 hereof,
        and each such determination shall be conclusive and binding on the
        Corporation and its shareholders. In making each such determination, the
        following factors shall, without excluding other factors determined by
        the Board of Directors to be relevant, be considered by the Board of
        Directors:

                (a)     in the case of any stock dividend payable in Cisco

                        number of Cisco Common Shares previously outstanding;

                (b)     in the case of the issuance or distribution of any
                        rights, options or warrants to subscribe for or purchase
                        Cisco Common Shares (or securities exchangeable for or
                        convertible into or carrying rights to

                        the Canadian Dollar Equivalent of the exercise price of
                        each such right, option or warrant and the Current
                        Market Price of a Cisco Common Share;

                (c)     in the case of the issuance or distribution of any other
                        form of property (including without limitation any
                        shares or securities of Cisco of any class other than
                        Cisco Common Shares, any rights, options or warrants

                        any evidences of indebtedness of Cisco or any assets of
                        Cisco), the relationship between the fair market value
                        (as determined by the Board of Directors in the manner
                        above contemplated) of such property to be issued or
                        distributed with respect to each outstanding Cisco
                        Common Share and the Current Market Price of a Cisco
                        Common Share;

                (d)     in the case of any subdivision, redivision or change of
                        the then outstanding Cisco Common Shares into a greater
                        number of Cisco Common Shares or the reduction,
                        combination, consolidation or change of the then
                        outstanding Cisco Common Shares into a lesser number of
                        Cisco Common Shares or any amalgamation, merger,
                        reorganization or other transaction affecting Cisco
                        Common Shares, the effect thereof upon the then
                        outstanding Cisco Common Shares; and

                (e)     in all such cases, the general taxation consequences of
                        the relevant event to holders of Exchangeable Shares to
                        the extent that such consequences may differ from the
                        taxation consequences to holders of Cisco Common Shares
                        as a result of differences between taxation laws of
                        Canada and the United States (except for any differing
                        consequences arising as a result of differing marginal
                        taxation rates and without regard to the individual
                        circumstances of holders of Exchangeable Shares).

        The restrictions in sections 4.1(a), 4.1(b), 4.1(c) and 4.1(d) above
        shall not apply if all dividends on the outstanding Exchangeable Shares
        corresponding to dividends declared and paid to date on the Cisco Common
        Shares shall have been declared and paid on the Exchangeable Shares.

        of each Exchangeable Share held by such holder on the effective date
        (the "Liquidation Date") of such liquidation, dissolution or winding-up,

        Amount") equal to the Current Market Price of an Cisco Common Share on

        satisfied in full by the Corporation causing to be delivered to such
        holder one Cisco Common Share, together with all declared and unpaid
        dividends on each such Exchangeable Share held by such holder on any

        securities register of the Corporation for the Exchangeable Shares or by
        holding for pick-up by the holder at the registered office of the
        Corporation or at any office of the Transfer Agent as may be specified
        by the Corporation by notice to the holders of Exchangeable Shares, on
        behalf of the Corporation of certificates representing Cisco Common
        Shares (which shares shall be duly issued as fully paid and
        non-assessable and shall be free and clear of any lien, claim or
        encumbrance) and a cheque of the Corporation payable at par at any
        branch of the bankers of the Corporation in respect of the declared and
        unpaid dividends on the Exchangeable Shares of such holder (in each case
        less any amounts withheld on account of tax required to be deducted and
        withheld therefrom). On and after the Liquidation Date, the holders of
        the Exchangeable Shares shall cease to be holders of such Exchangeable
        Shares and shall not be entitled to exercise any of the rights of
        holders in respect thereof, other than the right to receive their
        proportionate part of the total Liquidation Amount, unless payment of
        the total Liquidation Amount for such Exchangeable Shares shall not be
        made upon presentation and surrender of share certificates in accordance
        with the foregoing provisions, in which case the rights of the holders
        shall remain unaffected until the total Liquidation Amount has been paid
        in the manner hereinbefore provided. The Corporation shall have the
        right at any time after the Liquidation Date to deposit or cause to be
        deposited certificates representing the Cisco Common Shares issuable in
        respect of, and an amount representing declared and unpaid dividends on,
        the Exchangeable Shares represented by certificates that have not at the
        Liquidation Date been surrendered by the holders thereof in a custodial
        account with any chartered bank or trust company in Canada, and any
        interest allowed on such deposit shall belong to the Corporation. Upon
        such deposit being made, the rights of the holders of Exchangeable
        Shares after such deposit shall be limited to receiving their
        proportionate part of the total Liquidation Amount (in each case less
        any amounts withheld on account of tax required to be deducted and
        withheld therefrom) for such Exchangeable Shares so deposited, against
        presentation and surrender of the said certificates held by them,
        respectively, in accordance with the foregoing provisions. Upon such
        payment or deposit of the total Liquidation Amount, the holders of the
        Exchangeable Shares shall thereafter be considered and deemed for all
        purposes to be holders of the Cisco Common Shares delivered to them or
        the custodian on their behalf.

5.3     After the Corporation has satisfied its obligations to pay the holders
        of the Exchangeable Shares the Liquidation Amount per Exchangeable Share
        pursuant to section 5.1 of these share provisions, such holders shall
        not be entitled to share in any further distribution of the assets of
        the Corporation.

                                    ARTICLE 6
                   RETRACTION OF EXCHANGEABLE SHARES BY HOLDER

6.1     A holder of Exchangeable Shares shall be entitled at any time (but not
        more than once per calendar month), subject to the exercise by Cisco
        Newco of the



                                       28
<PAGE>   29

        Retraction Call Right and otherwise upon compliance with the provisions
        of this Article 6, to require the Corporation to redeem any or all of
        the Exchangeable Shares registered in the name of such holder for an
        amount per share (the "Retraction Price") equal to the Current Market
        Price of a Cisco Common Share on the last Business Day prior to the
        Retraction Date, which shall be satisfied in full by the Corporation
        causing to be delivered to such holder one Cisco Common Share for each
        Exchangeable Share presented and surrendered by the holder, together
        with, on the payment date therefor, the full amount of all declared and
        unpaid dividends on any such Exchangeable Share held by such holder on
        any dividend record date which occurred prior to the Retraction Date. To
        effect such redemption, the holder shall present and surrender at the
        registered office of the Corporation or at any office of the Transfer
        Agent as may be specified by the Corporation by notice to the holders of
        Exchangeable Shares the certificate or certificates representing the
        Exchangeable Shares which the holder desires to have the Corporation
        redeem, together with such other documents and instruments as may be
        required to effect a transfer of Exchangeable Shares under the CBCA and
        the by-laws of the Corporation and such additional documents and
        instruments as the Transfer Agent may reasonably require, and together
        with a duly executed statement (the "Retraction Request") in the form of
        Schedule A hereto or in such other form as may be acceptable to the
        Corporation:

                (a)     specifying that the holder desires to have all or any
                        number specified therein of the Exchangeable Shares
                        represented by such certificate or certificates (the
                        "RETRACTED SHARES") redeemed by the Corporation;

                (b)     stating the Business Day on which the holder desires to
                        have the Corporation redeem the Retracted Shares (the
                        "Retraction Date"), provided that the Retraction Date
                        shall be not less than 10 Business Days nor more than 15
                        Business Days after the date on which the Retraction
                        Request is received by the Corporation and further
                        provided that, in the event that no such Business Day is
                        specified by the holder in the Retraction Request, the
                        Retraction Date shall be deemed to be the 15th Business
                        Day after the date on which the Retraction Request is
                        received by the Corporation; and

                (c)     acknowledging the overriding right (the "Retraction Call
                        Right") of Cisco Newco to purchase all but not less than
                        all the Retracted Shares directly from the holder and
                        that the Retraction Request shall be deemed to be a
                        revocable offer by the holder to sell the Retracted
                        Shares to Cisco Newco in accordance with the Retraction
                        Call Right on the terms and conditions set out in
                        section 6.3 below.

6.2     Subject to the exercise by Cisco Newco of the Retraction Call Right,
        upon receipt by the Corporation or the Transfer Agent in the manner
        specified in section 6.1 hereof of a certificate or certificates
        representing the Retracted Shares, together



                                       29
<PAGE>   30

        with a Retraction Request, and provided that the Retraction Request is
        not revoked by the holder in the manner specified in section 6.7, the
        Corporation shall redeem the Retracted Shares effective at the close of
        business on the Retraction Date and shall deliver or cause to be
        delivered to such holder certificates representing the Cisco Common
        Shares to which such holder is entitled with respect to such shares, and
        on the designated payment date therefor, a cheque of the Corporation
        payable at par at any branch of the bankers of the Corporation in
        respect of any dividends on the Retracted Shares for which the record
        date was prior to the Retraction Date and the payment date was after the
        Retraction Date (in such case less any amounts withheld on account of
        tax required to be deducted and withheld therefrom). If only a part of
        the Exchangeable Shares represented by any certificate is redeemed (or
        purchased by Cisco Newco pursuant to the Retraction Call Right), a new
        certificate for the balance of such Exchangeable Shares shall be issued
        to the holder at the expense of the Corporation.

6.3     Upon receipt by the Corporation of a Retraction Request, the Corporation
        shall immediately notify Cisco Newco thereof and shall provide Cisco
        Newco with a copy of the Retraction Request. In order to exercise the
        Retraction Call Right, Cisco Newco must notify the Corporation of its
        determination to do so (the "Cisco Newco Call Notice") within five
        Business Days of notification to Cisco Newco by the Corporation of the
        receipt by the Corporation of the Retraction Request. If Cisco Newco
        does not so notify the Corporation within such five Business Day period,
        Cisco Newco will be deemed not to have exercised the Retraction Call
        Right. If Cisco Newco delivers the Cisco Newco Call Notice within such
        five Business Day period, and provided that the Retraction Request is
        not revoked by the holder in the manner specified in section 6.7, the
        Retraction Request shall thereupon be considered only to be an offer by
        the holder to sell the Retracted Shares to Cisco Newco in accordance
        with the Retraction Call Right. In such event, the Corporation shall not
        redeem the Retracted Shares and Cisco Newco shall purchase from such
        holder and such holder shall sell to Cisco Newco on the Retraction Date
        the Retracted Shares for a purchase price (the "Purchase Price") per
        share equal to the Current Market Price of a Cisco Common Share on the
        last Business Day prior to the Retraction Date, which shall be satisfied
        in full by Cisco Newco causing to be delivered to such holder one Cisco
        Common Share for each Exchangeable Share, plus, to the extent not paid
        by the Corporation, an additional amount equivalent to the full amount
        of all declared and unpaid dividends on those Retracted Shares held by
        such holder on any dividend record date which occurred prior to the
        Retraction Date (the "Dividend Amount"). For the purposes of completing
        a purchase pursuant to the Retraction Call Right, such Purchase Price
        shall be satisfied by Cisco Newco depositing with the Transfer Agent, on
        or before the Retraction Date, certificates representing Cisco Common
        Shares and a cheque or cheques of Cisco Newco payable at par at any
        branch of the bankers of Cisco Newco representing the aggregate Dividend
        Amount, less any amounts withheld on account of tax required to be
        deducted and withheld therefrom. Provided that Cisco Newco has complied
        with the immediately preceding sentence, the closing of the purchase and
        sale of the Retracted Shares pursuant to the Retraction Call Right shall
        be deemed to have occurred as at the



                                       30
<PAGE>   31

        close of business on the Retraction Date and, for greater certainty, no
        redemption by the Corporation of such Retracted Shares shall take place
        on the Retraction Date. In the event that Cisco Newco does not deliver a
        Cisco Newco Call Notice within such five Business Day period, and
        provided that the Retraction Request is not revoked by the holder in the
        manner specified in section 6.7, the Corporation shall redeem the
        Retracted Shares on the Retraction Date and in the manner otherwise
        contemplated in this Article 6.

6.4     The Corporation or Cisco Newco, as the case may be, shall deliver or
        cause the Transfer Agent to deliver to the relevant holder, at the
        address of the holder recorded in the securities register of the
        Corporation for the Exchangeable Shares or at the address specified in
        the holder's Retraction Request or by holding for pick-up by the holder
        at the registered office of the Corporation or at any office of the
        Transfer Agent as may be specified by the Corporation by notice to the
        holders of Exchangeable Shares, certificates representing the Cisco
        Common Shares (which shares shall be duly issued as fully paid and
        non-assessable and shall be free and clear of any lien, claim or
        encumbrance) registered in the name of the holder or in such other name
        as the holder may request, and, if applicable and on or before the
        payment date therefor, a cheque payable at par at any branch of the
        bankers of the Corporation or Cisco Newco, as applicable, representing
        the aggregate Dividend Amount in payment of the total Retraction Price
        or the total Purchase Price, as the case may be, in each case, less any
        amounts withheld on account of tax required to be deducted and withheld
        therefrom, and such delivery of such certificates and cheques on behalf
        of the Corporation or by Cisco Newco, as the case may be, or by the
        Transfer Agent shall be deemed to be payment of and shall satisfy and
        discharge all liability for the total Retraction Price or total Purchase
        Price, as the case may be, to the extent that the same is represented by
        such share certificates and cheques (plus any tax deducted and withheld
        therefrom and remitted to the proper tax authority).

6.5     On and after the close of business on the Retraction Date, the holder of
        the Retracted Shares shall cease to be a holder of such Retracted Shares
        and shall not be entitled to exercise any of the rights of a holder in
        respect thereof, other than the right to receive his proportionate part
        of the total Retraction Price or total Purchase Price, as the case may
        be, unless upon presentation and surrender of certificates in accordance
        with the foregoing provisions, payment of the total Retraction Price or
        the total Purchase Price, as the case may be, shall not be made as
        provided in section 6.4, in which case the rights of such holder shall
        remain unaffected until the total Retraction Price or the total Purchase
        Price, as the case may be, has been paid in the manner hereinbefore
        provided. On and after the close of business on the Retraction Date,
        provided that presentation and surrender of certificates and payment of
        the total Retraction Price or the total Purchase Price, as the case may
        be, has been made in accordance with the foregoing provisions, the
        holder of the Retracted Shares so redeemed by the Corporation or
        purchased by Cisco Newco shall thereafter be considered and deemed for
        all purposes to be a holder of the Cisco Common Shares delivered to it.



                                       31
<PAGE>   32

6.6     Notwithstanding any other provision of this Article 6, the Corporation
        shall not be obligated to redeem Retracted Shares specified by a holder
        in a Retraction Request to the extent that such redemption of Retracted
        Shares would be contrary to solvency requirements or other provisions of
        applicable law. If the Corporation believes that on any Retraction Date
        it would not be permitted by any of such provisions to redeem the
        Retracted Shares tendered for redemption on such date, and provided that
        Cisco Newco shall not have exercised the Retraction Call Right with
        respect to the Retracted Shares, the Corporation shall only be obligated
        to redeem Retracted Shares specified by a holder in a Retraction Request
        to the extent of the maximum number that may be so redeemed (rounded
        down to a whole number of shares) as would not be contrary to such
        provisions and shall notify the holder at least two Business Days prior
        to the Retraction Date as to the number of Retracted Shares which will
        not be redeemed by the Corporation. In any case in which the redemption
        by the Corporation of Retracted Shares would be contrary to solvency
        requirements or other provisions of applicable law, the Corporation
        shall redeem Retracted Shares in accordance with section 6.2 of these
        share provisions on a pro rata basis and shall issue to each holder of
        Retracted Shares a new certificate, at the expense of the Corporation,
        representing the Retracted Shares not redeemed by the Corporation
        pursuant to section 6.2 hereof. Provided that the Retraction Request is
        not revoked by the holder in the manner specified in section 6.7, the
        holder of any such Retracted Shares not redeemed by the Corporation
        pursuant to section 6.2 of these share provisions as a result of
        solvency requirements or other provisions of applicable law shall be
        deemed by giving the Retraction Request to require Cisco to purchase
        such Retracted Shares from such holder on the Retraction Date or as soon
        as practicable thereafter on payment by Cisco to such holder of the
        Purchase Price for each such Retracted Share, all as more specifically
        provided in the Voting and Exchange Trust Agreement.

6.7     A holder of Retracted Shares may, by notice in writing given by the
        holder to the Corporation before the close of business on the Business
        Day immediately preceding the Retraction Date, withdraw its Retraction
        Request, in which event such Retraction Request shall be null and void
        and, for greater certainty, the revocable offer constituted by the
        Retraction Request to sell the Retracted Shares to Cisco Newco shall be
        deemed to have been revoked.

                                    ARTICLE 7
              REDEMPTION OF EXCHANGEABLE SHARES BY THE CORPORATION

7.1     Subject to applicable law, and provided Cisco Newco has not exercised
        the Redemption Call Right, the Corporation shall on the Redemption Date
        redeem all but not less than all of the then outstanding Exchangeable
        Shares for an amount per share equal to the Current Market Price of an
        Cisco Common Share on the last Business Day prior to the Redemption Date
        (the "Redemption Price"), which shall be satisfied in full by the
        Corporation causing to be delivered to each holder of Exchangeable
        Shares one Cisco Common Share for each Exchangeable Share held by such
        holder, together with the full amount of all declared and unpaid



                                       32
<PAGE>   33

        dividends on each such Exchangeable Share held by such holder on any
        dividend record date which occurred prior to the Redemption Date.

7.2     In any case of a redemption of Exchangeable Shares under this Article 7,
        the Corporation shall, at least 60 days before the Redemption Date
        (other than a Redemption Date established in connection with an Cisco
        Control Transaction, an Exchangeable Share Voting Event or an Exempt
        Exchangeable Share Voting Event), send or cause to be sent to each
        holder of Exchangeable Shares a notice in writing of the redemption by
        the Corporation or the purchase by Cisco Newco under the Redemption Call
        Right, as the case may be, of the Exchangeable Shares held by such
        holder. In the case of a Redemption Date established in connection with
        an Cisco Control Transaction, an Exchangeable Share Voting Event and an
        Exempt Exchangeable Share Voting Event, the written notice of redemption
        by the Corporation or the purchase by Cisco Newco under the Redemption
        Call Right will be sent on or before the Redemption Date, on as many
        days prior written notice as may be determined by the Board of Directors
        of the Corporation to be reasonably practicable in the circumstances. In
        any such case, such notice shall set out the formula for determining the
        Redemption Price or the Redemption Call Purchase Price, as the case may
        be, the Redemption Date and, if applicable, particulars of the
        Redemption Call Right.

7.3     On or after the Redemption Date and subject to the exercise by Cisco
        Newco of the Redemption Call Right, the Corporation shall cause to be
        delivered to the holders of the Exchangeable Shares to be redeemed the
        Redemption Price for each such Exchangeable Share, together with the
        full amount of all declared and unpaid dividends on each such
        Exchangeable Share held by such holder on any dividend record date which
        occurred prior to the Redemption Date, upon presentation and surrender
        at the registered office of the Corporation or at any office of the
        Transfer Agent as may be specified by the Corporation in such notice of
        the certificates representing such Exchangeable Shares, together with
        such other documents and instruments as may be required to effect a
        transfer of Exchangeable Shares under the CBCA and the by-laws of the
        Corporation and such additional documents and instruments as the
        Transfer Agent may reasonably require. Payment of the total Redemption
        Price for such Exchangeable Shares, together with payment of such
        dividends, shall be made by delivery to each holder, at the address of
        the holder recorded in the securities register of the Corporation or by
        holding for pick-up by the holder at the registered office of the
        Corporation or at any office of the Transfer Agent as may be specified
        by the Corporation in such notice, on behalf of the Corporation of
        certificates representing Cisco Common Shares (which shares shall be
        duly issued as fully paid and non-assessable and shall be free and clear
        of any lien, claim or encumbrance) and, if applicable, a cheque of the
        Corporation payable at par at any branch of the bankers of the
        Corporation in payment of any such dividends, in each case, less any
        amounts withheld on account of tax required to be deducted and withheld
        therefrom. On and after the Redemption Date, the holders of the
        Exchangeable Shares called for redemption shall cease to be holders of
        such Exchangeable Shares and shall not be entitled to exercise any of
        the rights of



                                       33
<PAGE>   34

        holders in respect thereof, other than the right to receive their
        proportionate part of the total Redemption Price and any such dividends,
        unless payment of the total Redemption Price and any such dividends for
        such Exchangeable Shares shall not be made upon presentation and
        surrender of certificates in accordance with the foregoing provisions,
        in which case the rights of the holders shall remain unaffected until
        the total Redemption Price and any such dividends have been paid in the
        manner hereinbefore provided. The Corporation shall have the right at
        any time after the sending of notice of its intention to redeem the
        Exchangeable Shares as aforesaid to deposit or cause to be deposited
        certificates representing the Cisco Common Shares issuable in respect
        of, and the full amount of such dividends on (except as provided in this
        section 7.3), the Exchangeable Shares so called for redemption, or such
        of the said Exchangeable Shares represented by certificates that have
        not at the date of such deposit been surrendered by the holders thereof
        in connection with such redemption, in a custodial account with any
        chartered bank or trust company in Canada named in such notice, less any
        amounts withheld on account of tax required to be deducted and withheld
        therefrom. Upon the later of such deposit being made and the Redemption
        Date, the Exchangeable Shares in respect whereof such deposit shall have
        been made shall be redeemed and the rights of the holders thereof after
        such deposit or Redemption Date, as the case may be, shall be limited to
        receiving their proportionate part of the total Redemption Price and
        such dividends for such Exchangeable Shares so deposited, against
        presentation and surrender of the said certificates held by them,
        respectively, in accordance with the foregoing provisions. Upon such
        payment or deposit of the total Redemption Price and the full amount of
        such dividends, the holders of the Exchangeable Shares shall thereafter
        be considered and deemed for all purposes to be holders of the Cisco
        Common Shares delivered to them or the custodian on their behalf.

                                    ARTICLE 8
                            PURCHASE FOR CANCELLATION

8.1     Subject to applicable law and the articles of the Corporation, the
        Corporation may at any time and from time to time purchase for
        cancellation all or any part of the outstanding Exchangeable Shares at
        any price by tender to all the holders of record of Exchangeable Shares
        then outstanding or through the facilities of any stock exchange on
        which the Exchangeable Shares are listed or quoted at any price per
        share. If in response to an invitation for tenders under the provisions
        of this section 8.1, more Exchangeable Shares are tendered at a price or
        prices acceptable to the Corporation than the Corporation is prepared to
        purchase, the Exchangeable Shares to be purchased by the Corporation
        shall be purchased as nearly as may be pro rata according to the number
        of shares tendered by each holder who submits a tender to the
        Corporation, provided that when shares are tendered at different prices,
        the pro rating shall be effected (disregarding fractions) only with
        respect to the shares tendered at the price at which more shares were
        tendered than the Corporation is prepared to purchase after the
        Corporation has purchased all the shares tendered at lower prices. If

                        LEGEND; CALL RIGHTS; WITHHOLDINGS

13.1    The certificates evidencing the Exchangeable Shares shall contain or
        have affixed thereto a legend in form and on terms approved by the Board
        of Directors, with respect to the Support Agreement, the provisions of
        the Plan of Arrangement relating to the Liquidation Call Right and the
        Redemption Call Right, and the Voting and Exchange Trust Agreement
        (including the provisions with respect to the voting rights, exchange
        right and automatic exchange thereunder).

13.2    Each holder of an Exchangeable Share, whether of record or beneficial,
        by virtue of becoming and being such a holder shall be deemed to
        acknowledge each of the Liquidation Call Right, the Retraction Call
        Right and the Redemption Call Right, in each case, in favour of Cisco
        Newco, and the overriding nature thereof in connection with the
        liquidation, dissolution or winding-up of the Corporation or the
        retraction or redemption of Exchangeable Shares, as the case may be, and
        to be bound thereby in favour of Cisco Newco as therein provided.

13.3    The Corporation, Cisco Newco or Cisco shall be entitled to deduct and
        withhold from any dividend or consideration otherwise payable to any
        holder of Exchangeable Shares such amounts as the Corporation, Cisco
        Newco or Cisco are required to deduct and withhold with respect to such
        payment under the Income Tax Act (Canada) (including for greater
        certainty pursuant to Section 116 thereof), the United States Internal
        Revenue Code of 1986 or any provision of provincial, state, local or
        foreign tax law, in each case, as amended. To the extent that amounts
        are so withheld, such withheld amounts shall be treated for all purposes
        hereof as having been paid to the holder of the Exchangeable Shares in
        respect of which such deduction and withholding was made, provided that
        such withheld amounts are actually remitted to the appropriate taxing
        authority. To the extent that the amount so required or permitted to be
        deducted or withheld from any payment to a holder exceeds the cash
        portion of the consideration otherwise payable to the holder, the
        Corporation, Cisco Newco and Cisco are hereby authorized to sell or
        otherwise dispose of such portion of the consideration as is necessary
        to provide sufficient funds to the Corporation, Cisco Newco and Cisco as
        the case may be, to enable it to comply with such deduction or
        withholding requirement and the Corporation, Cisco Newco or Cisco shall
        notify the holder thereof and remit any unapplied balance of the net
        proceeds of such sale. All

        payments to be made hereunder shall be made without interest and less
        any tax required by Canadian law to be deducted and withheld.

                To 3801110 Canada Inc. (the "Corporation") and 3045848 Nova
Scotia Company ("Cisco Newco").

                This notice is given pursuant to Article 6 of the provisions
(the "Share Provisions") attaching to the Exchangeable Shares of the Corporation
represented by this certificate and all capitalized words and expressions used
in this notice that are defined in the Share Provisions have the meanings
ascribed to such words and expressions in such Share Provisions.

                The undersigned hereby notifies the Corporation that, subject to
the Retraction Call Right referred to below, the undersigned desires to have the
Corporation redeem the following Exchangeable Shares (the "Retracted Shares") in
accordance with Article 6 of the Share Provisions:

     [ ]       all share(s) represented by this certificate; or

     [ ]       __________ share(s) only.

               The undersigned hereby notifies the Corporation that the
Retraction Date shall be ________.

NOTE:

        The Retraction Date must be a Business Day and must not be less than 10
        Business Days nor more than 15 Business Days after the date upon which
        this notice is received by the Corporation. If no such Business Day is
        specified above, the Retraction Date shall be deemed to be the 15th
        Business Day after the date on which this notice is received by the
        Corporation.

                The undersigned acknowledges the overriding Retraction Call
Right of Cisco Newco to purchase all but not less than all the Retracted Shares
from the undersigned and that this notice is and shall be deemed to be a
revocable offer by the undersigned to sell the Retracted Shares to Cisco Newco
in accordance with the Retraction Call Right on the Retraction Date for the
Purchase Price and on the other terms and conditions set out in section 6.3 of
the Share Provisions. This notice of retraction, and this offer to sell the
Retracted Shares to Cisco Newco, may be revoked and withdrawn by the undersigned
only by notice in writing given to the Corporation at any time before the close
of business on the Business Day immediately preceding the Retraction Date.

                The undersigned acknowledges that if, as a result of solvency
provisions of applicable law, the Corporation is unable to redeem all Retracted
Shares and provided Cisco Newco shall not have exercised the Retraction Call
Right with respect to the Retracted Shares and the undersigned has not revoked
this notice of retraction, the undersigned will be deemed to have exercised the
Exchange Right (as defined in the Voting and Exchange Trust Agreement) so as to
require Cisco Systems, Inc. to purchase the unredeemed Retracted Shares.

                        the Waiver, the transaction contemplated hereby will not
                        terminate any of the outstanding options under the
                        relevant Pixstream Stock Option Plan or accelerate the

                        Common Shares which will be subject to those options
                        upon Cisco's assumption of the options;

                        by the Bank of Canada;

                (iii)   each outstanding U.K. Option shall be exchanged by Cisco
                        for an option to acquire Cisco Common Shares as set
                        forth below, provided the holder of each such option has
                        consented to such exchange and Cisco has received U.K.
                        Inland Revenue approval for such exchanged option to
                        continue to be treated as an approved option under
                        Schedule 9 of the U.K. Income and Corporation Taxes Act

                        Agreement shall continue to have, and be subject to, the
                        same terms and conditions set forth in the U.K. Plan and
                        the applicable stock option agreements, immediately
                        prior to the Effective Time, except that (i) such option
                        will be exercisable for that number of whole Cisco
                        Common Shares equal to the product of the number of
                        Pixstream Common Shares that were issuable upon exercise
                        of such option immediately prior to the Effective Time
                        multiplied by the Exchange Ratio and rounded down to the
                        nearest whole number of Cisco Common Shares, and (ii)
                        the per share exercise price for the Cisco Common Shares
                        issuable upon exercise of such exchanged option will be
                        equal to the quotient determined by dividing the
                        exercise price per Pixstream Common Share at which such
                        option was exercisable immediately prior to the

                        with the terms of the U.K. Plan and the documents
                        governing the outstanding options under such Plan, the
                        transaction contemplated hereby will not terminate any
                        of the outstanding options under the U.K. Plan or
                        accelerate the exercisability or vesting of such options
                        or the Cisco Common Shares which will be subject to
                        those options upon Cisco's exchange of the options at
                        the Effective Time. In the event U.K. Inland Revenue
                        approval is not obtained, then the U.K. Options shall be
                        assumed by Cisco as provided in Section 2.2(h)(i) above.

                numerator of which is $352.762 million less the amount of any
                Pixstream Expenses less $5.22 times the difference between
                1,140,000 and the number of Pixstream Options granted between

                and (y) the total number of Pixstream Common Shares issued and
                outstanding on a fully diluted basis at the Effective Time
                (after giving effect to the conversion, exchange or exercise, as
                the case may be, of all securities convertible into, or

                                   APPENDIX II

        RIGHTS, PRIVILEGES, RESTRICTIONS AND CONDITIONS ATTACHING TO THE
                   COMMON SHARES AND SPECIAL SHARES OF AMALCO



A.      SPECIAL SHARES

1.      Dividends

        (a) The holders of the special shares, in priority to the common shares
and all other shares ranking junior to the special shares, shall be entitled to
receive and the Corporation shall pay thereon, as and when declared by the board
of directors of the Corporation out of the assets of the Corporation properly
applicable to the payment of dividends, cumulative cash dividends at the rate of
8% per annum of the Redemption Price (as hereinafter defined) payable on the
first days of January, April, July and October in each year. Cheques of the
Corporation payable at par at any branch of the Corporation's bankers in Canada
shall be issued in respect of such dividends and payment thereof shall satisfy
such dividends. Such dividends shall accrue from such date or dates not later
than six months after the respective dates of issue as may in the case of each
issue be determined by the board of directors of the Corporation or in case no
date be so determined then from the date of issue. If on any dividend payment
date, the dividend payable on such date is not paid in full on all of the
special shares then issued and outstanding, such dividend, or the unpaid part
thereof, shall be paid at a subsequent date or dates as and when declared by the
board of directors. The holders of the special shares shall not be entitled to
any dividends other than or in excess of the dividends hereinbefore provided
for.

        (b) Except with the consent in writing of the holders of all of the
special shares outstanding, no dividend shall at any time be declared and paid
on or declared and set apart for payment on the common shares or on any other
shares of the Corporation ranking junior to the special shares for any financial
year unless all cumulative cash dividends on the special shares then issued and
outstanding in respect of such financial year shall have been declared and paid
or set apart for payment at the date of such declaration and payment or setting
apart of dividends on the common shares or on any other shares ranking junior to
the special shares.

2.      Liquidation, Dissolution or Winding-Up

        In the event of the liquidation, dissolution or winding-up of the
Corporation or other distribution of assets of the Corporation among
shareholders for the purpose of winding-up its affairs, the holders of the
special shares, in priority to the holders of the common shares, shall be
entitled to receive from the assets of the Corporation a sum equivalent to the
aggregate Redemption Price (as hereinafter defined)



                                       50
<PAGE>   51

of all of the special shares held by them plus all accrued and unpaid cumulative
cash dividends thereon up to but not including the date of distribution. After
payment to the holders of the special shares of the amount so payable to them as
above provided they shall not be entitled to share in any further distribution
of the assets of the Corporation.

3.      Redemption

                (a) The Corporation may, subject to the requirements of the
Canada Business Corporations Act (the "Act"), upon giving notice as hereinafter
provided, redeem at any time the whole, or from time to time any part, of the
then outstanding special shares on payment of a redemption price of [$?] per
share [NOTE: THIS AMOUNT WILL BE INSERTED IN THE ARTICLES OF ARRANGEMENT AND
WILL BE EQUAL TO CDN. $12.8 MILLION DIVIDED BY THE AGGREGATE NUMBER OF SPECIAL
SHARES INTO WHICH THE PIXSTREAM COMMON SHARES AND THE HOLDCO COMMON SHARES ARE
CONVERTED ON THE AMALGAMATION] (the "Redemption Price"), plus all accrued and
unpaid cumulative cash dividends thereon up to but not including the date of
redemption (such Redemption Price plus the per share dividend being herein
referred to together as the "Redemption Amount").


        (b) In the case of redemption of special shares under the provisions of
sub-clause 3(a) hereof, the Corporation shall, unless waived in writing by the
holders of all of the special shares to be redeemed, at least 10 days before the
date specified for redemption deliver or mail to each person who at the date of
mailing is a registered holder of special shares to be redeemed a notice in
writing of the intention of the Corporation to redeem such special shares. Such
notice shall be delivered or mailed by letter, postage prepaid, addressed to
each such shareholder at the shareholder's address as it appears on the records
of the Corporation or in the event of the address of any such shareholder not so
appearing then to the last known address of such shareholder or if delivered,
delivered to each such shareholder at such address; provided, however, that
accidental failure to give any such notice to one or more of such shareholders
shall not affect the validity of such redemption. Such notice shall set out the
Redemption Amount and 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 to be so redeemed; provided, however, that if a part only of
the special shares for the time being outstanding is to be redeemed, the shares
so to be redeemed shall be selected by lot in such manner as the directors in
their discretion shall decide or if the directors so determine may be redeemed
pro rata (disregarding fractions) unless otherwise agreed in writing by the
holders of all of the special shares. On the date so specified for redemption,
the Corporation shall pay or cause to be paid to or to the order of the
registered holders of the special shares to be redeemed the Redemption Amount
thereof on presentation and surrender at the registered office of the
Corporation or any other place designated in such notice of the certificates
representing the special shares called for redemption. Such payment shall be
made by cheque payable at par at any branch of the Corporation's bankers in
Canada. If less than all of the special shares represented by any certificate
are redeemed the holder shall be entitled to receive a new certificate for that
number of special shares represented by the original certificate which are not



                                       51
<PAGE>   52

redeemed. From and after the date specified for redemption in any such notice
the holders of the special shares called for redemption shall cease to be
entitled to dividends and shall not be entitled to exercise any of the rights of
shareholders in respect thereof unless payment of the Redemption Amount shall
not be made upon presentation of certificates in accordance with the foregoing
provisions, in which case the rights of shareholders shall remain unaffected.
The Corporation shall have the right at any time after the mailing of notice of
its intention to redeem any special shares to deposit the Redemption Amount for
the shares so called for redemption or of such of the said shares represented by
certificates as have not at the date of such deposit been surrendered by the
holders thereof in connection with such redemption to a special account in any
chartered bank or in any trust Corporation in Canada, named in such notice, to
be paid without interest to or to the order of the respective holders of such
special shares called for redemption upon presentation and surrender to such
bank or trust Corporation of the certificates representing the same. Upon such
deposit being made or upon the date specified for redemption in such notice,
whichever is the later, the special shares in respect whereof such deposit shall
have been made shall be redeemed and the rights of the holders thereof after
such deposit or such redemption date, as the case may be, shall be limited to
receiving without interest their proportionate part of the total Redemption
Amount so deposited against presentation and surrender of the said certificates
held by them respectively and any interest on the amount so deposited shall be
for the account of the Corporation. If any part of the total Redemption Amount
so deposited has not been paid to or to the order of the respective holders of
the special shares which were called for redemption within two years after the
date upon which such deposit was made or the date specified for redemption in
the said notice, whichever is the later, such balance remaining in the said
special account shall be returned to the Corporation without prejudice to the
rights of the holders of the shares being redeemed to claim the Redemption
Amount to which they are entitled without interest from the Corporation.

4.      Retraction

        Any holder of special shares shall be entitled to require the
Corporation to redeem, subject to the requirements of the Act, at any time or
times all or any of the special shares registered in the name of such holder on
the books of the Corporation by tendering to the Corporation at the registered
office of the Corporation a share certificate or certificates representing the
special shares which the registered holder desires to have the Corporation
redeem together with a notice in writing specifying (i) that the registered
holder desires to have the special shares represented by such certificate or
certificates redeemed by the Corporation and (ii) the business day ("Retraction
Date") on which the holder desires to have the Corporation redeem such special
shares. The Retraction Date shall not be less than 30 days after the day on
which the notice in writing is given to the Corporation without the consent of
the Corporation. Upon receipt of a share certificate or certificates
representing the special shares which the registered holder desires to have the
Corporation redeem together with such notice, the Corporation shall on the
Retraction Date redeem such special shares by paying to such registered holder
the Redemption Amount for each such special share being redeemed. Such payment
shall be made by a cheque payable at par at any branch of the Corporation's
bankers for the time being in Canada. If less than all of the special shares
represented by any certificate are redeemed,



                                       52
<PAGE>   53

the holder shall be entitled to receive a new certificate for that number of
special shares represented by the original certificate or certificates which are
not redeemed. The said special shares shall be redeemed on the Retraction Date
and from and after the Retraction Date the holder of such shares shall cease to
be entitled to dividends and shall not be entitled to exercise any of the rights
of holders of special shares in respect thereof unless payment of the Redemption
Amount is not made on the Retraction Date, in which event the rights of the
holder of the said special shares shall remain unaffected.

5.      Voting

        Except as otherwise provided by law, the holders of the special shares
shall not be entitled as such to receive notice of, or to attend, any meeting of
the shareholders of the Corporation and shall not be entitled to vote at any
such meeting or to sign any resolution in writing in lieu thereof.

B.      COMMON SHARES

1.      Dividends

        Subject to the prior rights of the holders of the special shares and not
otherwise, the board of directors may declare and cause to be paid dividends to
the holders of the common shares from any assets at the time properly applicable
to the payment of dividends.

2.      Liquidation, Dissolution or Winding-Up

        In the event of liquidation, dissolution or winding-up of the
Corporation or other distribution of assets of the Corporation among
shareholders for the purpose of winding-up its affairs, subject to the prior
rights of the holders of the special shares, the holders of the common shares
shall be entitled to receive the remaining assets of the Corporation.

3.      Voting

        The holders of the common shares shall be entitled to receive notice of
and to attend any meeting of the shareholders of the Corporation and shall be
entitled to one vote in respect of each common share held at such meetings,
except a meeting of holders of a particular class of shares other than the
common shares who are entitled to vote separately as a class at such meeting.

4.      Other Provisions

        Notwithstanding the provisions of the foregoing, the directors shall not
declare and the Corporation shall not at any time pay a dividend on the common
shares or any other shares ranking junior to the special shares, or redeem or
purchase for cancellation or make a capital distribution in respect of the
common shares or any other shares ranking junior to the special shares unless,
after giving effect to such action, the



                                       53
<PAGE>   54

Corporation will be able to redeem all of the issued special shares pursuant to
clauses A.3 and A.4.
