from January 1st, 2001 to October 31st, 2001 and can be extended by mutual
consent of the parties, prior to its expiration. Any extension shall be made in
writing.

CLAUSE FIVE: PRICE. The price which ECOPETROL will pay to SELLER for the crude
oil delivered at the Santana Terminal, is defined as follows: Price = Base Price
plus or less quality adjustment, less transport, less transport tax, less
marketing value.  PARAGRAPH 1: Base Price shall be the weighted average of the
export loads invoiced by ECOPETROL during that month.  PARAGRAPH 2:  Quality
adjustment applied hereunder shall be for API Gravity and Sulfur contents and
shall be estimated on a monthly basis according to the procedure described in
Attachment No. 1. PARAGRAPH 3: For estimation purposes of the transport variable
and of the transport tax, the basis to apply the rate set forth by the

                                                                               2
<PAGE>

Ministry of Mines and Energy shall be the number of gross barrels transported.
The transport tax shall be estimated on the total number of net barrels
transported. The Pipeline Transport Rules shall be considered part to this
Contract once approved by the parties and after being subject to the official
approvals which could be required. PARAGRAPH 4: The Santana - Tumaco transport
cost, as well as the respective transport tax shall be subject to any change
made in this connection during contract term. Santana - Tumaco transport rate
corresponds to the rate set forth in Resolution number 6031 of May 8th, 1998 of
the Ministry of Mines and Energy. Transport tax shall be 2% (two per cent) of
the rate, pursuant to Article 17 of Decree 2140 of 1955 adopted permanently by
Law 10, 1961. These rates shall be readjusted on a yearly basis pursuant to the
aforementioned Resolution No. 6031. PARAGRAPH 5: The Marketing cost shall be of
0.165 USD/BL. PARAGRAPH 6: In the event that no exports of South Blend crude are
made, the following will be taken into consideration:

     a)   If during one month or several consecutive months there are no South
          Blend crude oil exports, the provisional invoicing price shall be the
          price estimated taking as base price, the export price of the previous
          month. In order to estimate the definite price to be used as base
          price, the export price of the crude exports conducted in a month
          following the month or the months for whom the provisional price
          estimate was made, will be used. Once the definite price is estimated,
          the parties will draft the corresponding balance as the case may be.

          The quality adjustment will be estimated using the procedure described
          in Attachment 1.

          In the event that during the last month of the contract and during the
          previous months no exports of South Blend Crude are made, and nor are
          they made during the immediately following month to the last month of
          the contract term, the provisional price estimated for this (these)
          month(s) will be considered as the definite price.

     b)   In the event that no South Blend Crude Oil exports are carried out for
          more than three consecutive months, the provisional invoicing of the
          first three months will be carried out as described in item a)
          hereunder. For deliveries made from the fourth month on, seller can
          only invoice such deliveries until one or several exports of South
          Blend Crude Oil are carried out in one month within the term of the
          contract. For the first three months provisionally invoiced and for
          the months with pending invoicing, the base price shall be the value
          of the aforementioned export(s).

     c)   In the event that during the last month of the contract and during the
          previous months no exports of South Blend Crude are made, and nor are
          they made during the immediately following month to the last month of
          the contract term, the definite prices for deliveries pending
          invoicing will be estimated taking as base prices the prices of the
          last export(s) of South Blend Crude made through the Tumaco Port.
          Quality adjustment of the provisional price and definite price shall
          be estimated according to the procedures described in Attachment 1.
          For the first three months during which no exports were carried out,
          provisions described in item a) hereunder shall apply.

PARAGRAPH 7: In case of coastwise shipping of Tumaco's oil (South Blend) to the
Refinery of Cartagena, sale and price ECOPETROL will pay to SELLER shall be the
same

                                                                               3
<PAGE>

obtained by the International Trade Management for the South Blend of Tumaco
(FOB Tumaco) received by the Refinery of Cartagena as a result of a bid plus or
less the quality adjustment, less the Santana - Tumaco transport cost and the
respective tax, less marketing (USD 0.165 per barrel). In case the Cartagena
Refinery purchases South Blend Crude Oil without a bid, the parties shall agree
on the mechanism to be used to estimate the crude oil's price. PARAGRAPH 8:
Notwithstanding the provisions set forth in Paragraph 2 concerning the quality
adjustment procedure, the parties can agree on a review of the crude oil market
and of the present method, and for this purpose they can resort to a mutual
consent on the crude oils to eliminate or add to the present market. In
addition, the parties can also hire an external consultant to determine whether
they should continue with the present method or they should use a new method. In
case parties do not reach an agreement in this connection, the present method
will continue to be applied. If it is necessary to apply a new method, it shall
be effective as of the deliveries made during the month when the agreement was
reached.

CLAUSE SIX: INVOICING AND FORM OF PAYMENT: SELLER shall invoice to ECOPETROL in
its Bogota Office, within the first 10 days of each month, the crude oil
delivered to ECOPETROL during the previous month after deducting the value
corresponding to royalties, contributions, and participations. Within 7 days of
the aforementioned term, ECOPETROL shall give SELLER the information it may
require to make the corresponding invoicing. Payment shall be made on a monthly
basis 30 days after receipt of invoice by ECOPETROL, after making the lawful
withholdings, if any. SELLER will inform ECOPETROL in writing at the time of
submission of the invoices about the percentages to apply on the net deliveries
of SELLER in order to determine the value to be paid in pesos and the value to
be paid in dollars. The percentages which can be applied on net deliveries are:
25% in pesos and 75% in dollars or 50% in pesos and 50% in dollars or 75% in
pesos and 25% in dollars. Invoicing shall be made based on the net volume, free
of water and sediment, adjusted at 60 degrees F. For the portion in Colombian
pesos the market's representative exchange rate shall be used according to
certification by the Banking Superintendency, estimated as the arithmetic
average corresponding to the month when deliveries were made. PARAGRAPH 1: In
Case of delay in payment of the dollars portion on invoices not timely rejected
by ECOPETROL, ECOPETROL shall pay to SELLER as interest in dollars, the "Libor"
interest rate during the days of delay plus 1.0%. In case of delay in payment of
the pesos portion, ECOPETROL shall pay the maximum monthly interest rate
certified by the Banking Superintendency. Invoices collecting interests in pesos
or dollars shall be paid within the ten (10) days following receipt by
ECOPETROL. PARAGRAPH 2: If ECOPETROL should not have United States of America
dollars available or should it be unable to get them from the Colombian
government or its authorized agencies, in order to cover the crude oil purchases
hereunder, it shall give notice, as soon as possible, and in writing to SELLER,
without prejudice as to the conditions set forth in paragraph 1 above, and the
parities shall have a maximum 30 calendar days term as of such notice of
ECOPETROL, to reach a mutual agreement and an adequate solution. PARAGRAPH 3:
ECOPETROL shall have a 15 working days term to check, correct or reject invoices
filed by SELLER. Invoices not rejected within this term shall be deemed final
and correct. Any adjustment or correction required shall change the valid date
of the invoice to the date when the adjustment or correction is made effective
before ECOPETROL. ECOPETROL shall inform SELLER within the term set forth about
any rejected invoice in order for it to be adjusted and

                                                                               4

corrected, clearly specifying the items which need to be adjusted or corrected
and the reason for such objection or correction.

CLAUSE SEVEN: INSPECTION AND MEASUREMENT. For the purpose of Clause Two, quality
will be determined pursuant to operational procedures set forth at the Santana
Station. Costs of these procedures shall be shared by the parties at a rate
proportionate to  their ownership of the crude oil. In addition to these
operational procedures, any of the parties can appoint when so desired an
Independent Inspector to certify the amount and quality, to measure the capacity
of the tanks and to gauge volume measurement instruments. In this latter case,
the party requesting measurement shall bear with costs.

CLAUSE EIGHT: DESTINATION. ECOPETROL can do as it pleases with the purchased
crude oil, provided that such destination is approved by applicable legal
provisions at this time.

CLAUSE NINE: ASSIGNMENT. Neither party can assign, sell or transfer all or part

impossibility to meet its obligations such as: natural phenomena (earthquakes,
floods, land slides) or public order events (strikes, mutiny, terrorism,
sabotage, breakage of the pipeline). The obligations that cannot be fulfilled
due to Force Majeure shall be suspended during the term of the Force Majeure
which prevents contract compliance, provided that the party affected by Force
Majeure gives notice to the other party, as soon as possible, using an adequate
means for this purpose, about such situation, with as many details as possible.
Such notice shall be confirmed through a notice sent to the other party within a
forty eight (48) hours term after the Force Majeure event or after the party has
decided to resort to this clause, including all the evidences showing the
occurrence of the Force Majeure event. Once the event is duly proven, the
suspension of the obligations shall be recorded in a Minutes signed by the
Parties. The Party that decides to abide under this item must do its best to
solve the problems preventing it from complying with its obligations. After
overcoming the Force Majeure events, the parties shall sign a minutes verifying
the date when suspended obligations are resumed. Force Majeure shall not relieve
ECOPETROL from its obligation to pay SELLER those invoices filed for the sale of
crude oil delivered by SELLER pursuant to the terms of Clause Three hereunder.

CLAUSE ELEVEN: TERMINATION. This contract can be subject to early termination
for causes imputable to Force Majeure or Acts of God that prevent contract
execution during a term exceeding 90 continuous calendar days.

CLAUSE TWELVE: APPLICATION OF COLOMBIA LAW. For all purposes hereunder, the
parties hereby appoint as contract domicile the city of Bogota D.C., Republic of
Colombia. This contract shall be ruled by the Colombian law and the parties

aspects regarding interpretation and execution of the contract which cannot be
amicably settled shall be put to the consideration and decision of the judicial
branch of Colombia. B) All factual or technical differences arising between the
parties which cannot be amicably settled, shall be submitted to the final
decision of experts appointed as follows:  one by each party and a third one
appointed by common consent of the two main experts appointed by the parties. If

     notice of redemption, extension or acceleration to less than 10% of such
     holders of Exchangeable Shares shall not affect the validity of such

2.1  The Exchangeable Shares shall be entitled to a preference over the Common
Shares and any other shares ranking junior to the Exchangeable Shares with
respect to the payment of dividends and distribution of assets in the event of
the liquidation, dissolution or winding-up of the Corporation, whether voluntary

                                   DIVIDENDS

3.1  Subject to the prior rights of the holders of any other class of shares
ranking senior to the Exchangeable Shares with respect to priority in the
payment of dividends, a holder of an Exchangeable Share shall be entitled to
receive and the Board of Directors shall, subject to applicable law, on each
MetaSolv Dividend Declaration Date, declare a dividend on each Exchangeable
Share:

     (a)  in the case of a cash dividend declared on the MetaSolv Common Shares,
          in an amount in cash for each Exchangeable Share in U.S. dollars, on

     (b)  in the case of a stock dividend declared on the MetaSolv Common Shares
          to be paid in MetaSolv Common Shares, in such number of Exchangeable
          Shares for each
<PAGE>

                                      -7-

          Exchangeable Share as is equal to the number of MetaSolv Common Shares
          to be paid on each MetaSolv Common Share, or

     (c)  in the case of a dividend declared on the MetaSolv Common Shares in
          property other than cash or MetaSolv Common Shares, in such type and
          amount of property for each Exchangeable Share as is the same as or
          economically equivalent to (to be determined by the Board of Directors
          as contemplated by Section 3.5) the type and amount of property
          declared as a dividend on each MetaSolv Common Share.

Such dividends shall be paid out of money, assets or property of the Corporation
properly applicable to the payment of dividends, or out of authorized but
unissued shares of the Corporation.  Any dividend which should have been
declared on the Exchangeable Shares pursuant to this Section 3.1 but was not so
declared due to the provisions of applicable law shall be declared and paid by
the Corporation as soon as payment of such dividend is permitted by such law on
a subsequent date or dates determined by the Board of Directors.

3.2  Cheques of the Corporation or any dividend paying agent appointed by the
Corporation payable at par at any branch of the bankers of the Corporation shall
be issued in respect of any cash dividends contemplated by Section 3.1(a) hereof
and the sending of such a cheque to each holder of an Exchangeable Share shall
satisfy the cash dividend represented thereby unless the cheque is not paid on
presentation. Certificates registered in the name of the registered holder of
Exchangeable Shares shall be issued or transferred in respect of any stock
dividends contemplated by Section 3.1(b) hereof and the sending of such a
certificate to each holder of an Exchangeable Share shall satisfy the stock
dividend represented thereby. Such other type and amount of property in respect

thereby. No holder of an Exchangeable Share shall be entitled to recover by
action or other legal process against the Corporation any dividend that is
represented by a cheque that has not been duly presented to the Corporation's
bankers for payment or that otherwise remains unclaimed for a period of six
years from the date on which such dividend was payable.

3.3  The record date for the determination of the holders of Exchangeable Shares
entitled to receive payment of, and the payment date for, any dividend declared
on the Exchangeable Shares under Section 3.1 hereof shall be the same dates as
the record date and payment date, respectively, for the corresponding dividend
declared on the MetaSolv 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.

                             CERTAIN RESTRICTIONS

4.1  So long as any of the Exchangeable Shares are outstanding, the Corporation
shall not at any time without, but may at any time with, the approval of the
holders of the Exchangeable Shares given as specified in Section 10.2 of these
share provisions:

     (a)  pay any dividends on the Common Shares or any other shares ranking
          junior to the Exchangeable Shares, other than stock dividends payable
          in Common Shares or any such other shares ranking junior to the
          Exchangeable Shares, as the case may be;

     (b)  redeem, retract or purchase or make any capital distribution in
          respect of Common Shares or any other shares ranking junior to the
          Exchangeable Shares;

     (c)  redeem or purchase any other shares of the Corporation ranking equally
          with or junior to the Exchangeable Shares with respect to the payment
          of dividends or on any liquidation distribution; or

     (d)  issue any Exchangeable Shares or any other shares of the Corporation
          ranking equally with respect to the payment of dividends or on any
          liquidation distribution, or superior to, the Exchangeable Shares
          other than by way of stock dividends to the holders of such
          Exchangeable Shares or as contemplated by the Support Agreement.

The foregoing restrictions shall not apply if all dividends on the outstanding
Exchangeable Shares corresponding to dividends declared following the initial
date of issue of Exchangeable Shares on the MetaSolv Common Shares shall have
been declared on the Exchangeable Shares and paid in full.

                          DISTRIBUTION ON LIQUIDATION

<PAGE>

                                      -9-

5.1  In the event of the liquidation, dissolution or winding-up of the
Corporation or any other distribution of the assets of the Corporation among its
shareholders for the purpose of winding up its affairs, a holder of Exchangeable
Shares shall be entitled, subject to applicable law and subject to the prior
rights of all classes of shares ranking senior to the Exchangeable Shares, to
receive from the assets of the Corporation in respect of each Exchangeable Share
held by such holder on the effective date (the "Liquidation Date") of such
liquidation, dissolution or winding-up, before any distribution of any part of
the assets of the Corporation among the holders of the Common Shares or any
other shares ranking junior to the Exchangeable Shares, an amount per share
equal to:

     (a)  the Current Market Price of a MetaSolv Common Share on the last
          Business Day prior to the Liquidation Date, which shall be satisfied
          in full by the Corporation causing to be delivered to such holder one
          MetaSolv Common Share (subject to adjustment as provided for in
          Section 11.1), plus

     (b)  an additional amount equivalent to the full amount of all declared and
          unpaid dividends on each such Exchangeable Share and all dividends
          declared on MetaSolv Common Shares which have not been declared on
          such Exchangeable Shares in accordance with Section 3.1 of these
          share provisions

(collectively the "Liquidation Amount", provided that if the record date for any
such declared and unpaid dividends occurs after the Liquidation Date, the
Liquidation Amount shall not include such additional amount equivalent to such
dividends).

5.2  On or promptly after the Liquidation Date, and subject to the exercise by
MetaSolv AcquisitionCo of the Liquidation Call Right, the Corporation shall
cause to be delivered to the holders of the Exchangeable Shares the Liquidation
Amount (less any tax required to be deducted and withheld therefrom by the
Corporation) for each such Exchangeable Share upon presentation and surrender 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 Act and the Articles of Association of the
Corporation and such additional documents and instruments as the Corporation may
reasonably require (including, without limitation, a statutory declaration as to
the holder being a resident of Canada for the purposes of the Tax Act or a
certificate issued under section 116 of the Tax Act in form and substance, and
with a certificate limit, acceptable to the Corporation, subject to the last
sentence of this Section 5.2), at the registered office of the Corporation or at
such other address as may be specified by the Corporation by notice to the
holders of the Exchangeable Shares. Payment of the total Liquidation Amount for
such Exchangeable Shares shall be made by delivery to each holder, at the
address of the holder recorded in the 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 such other address as may be
specified by the Corporation by notice to the holders of the Exchangeable
Shares, certificates representing MetaSolv Common Shares (which shares shall be
duly issued as fully paid and non-assessable and
<PAGE>

                                      -10-

shall be free and clear of any lien, claim or encumbrance) registered in the
name of the holder and a cheque of the Corporation payable at part at any branch
of the bankers of the Corporation in respect of the amount equivalent to the
full amount of all declared and unpaid dividends and all dividends declared on
MetaSolv Common Shares which have not been declared on such Exchangeable Shares
in accordance with Section 3.1 of these share provisions, comprising part of the
total Liquidation Amount (less any tax required to be deducted and withheld
therefrom by the Corporation). 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 the total Liquidation Amount in respect of 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. 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 (less any 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 MetaSolv Common Shares delivered to them. To the extent
that the amount of tax required to be deducted or withheld from any payment to a
holder of Exchangeable Shares exceeds the cash portion of such payment, the
Corporation and MetaSolv AcquisitionCo is hereby authorized to sell or otherwise
dispose of at fair market value such portion of the property then payable to the
holder as is necessary to provide sufficient funds to the Corporation and
MetaSolv AcquisitionCo, after payment of any costs or expenses of such sale, in
order to enable it to comply with such deduction or withholding requirement and
the Corporation and MetaSolv AcquisitionCo shall give an accounting to the
holder with respect thereto and any balance of such proceeds of sale. To the
extent that the Corporation or MetaSolv AcquisitionCo has sold the property
payable to the holder as contemplated herein, the Corporation and MetaSolv
AcquisitionCo shall be entitled to withhold such portion of the consideration to
which such non-resident shareholder would otherwise be entitled until such time
as the holder provides to the Corporation and MetaSolv AcquisitionCo an
appropriate certificate issued under section 116 of the Tax Act and any
applicable provincial equivalent or an equivalent amount in cash or certified
funds in an amount equal to the amount the Corporation and MetaSolv
AcquisitionCo is required to remit to the Canada Customs and Revenue Agency on
behalf of the non-resident shareholder if such a certificate is not provided,
and the Corporation and MetaSolv AcquisitionCo shall be entitled to remit said
amount to said Agency on behalf of the holder upon the expiry of the applicable
period at which time the funds are required to be remitted to the Agency. The
Corporation and MetaSolv AcquisitionCo shall also be entitled to withhold from
such consideration an amount sufficient to indemnify the Corporation and
MetaSolv AcquisitionCo
<PAGE>

                                      -11-

for all of its costs of disposing of the MetaSolv Common Shares as hereinbefore
contemplated. If, in connection with such exchange, MetaSolv AcquisitionCo or
the Corporation is required to advance funds on its own account to the Canada
Customs and Revenue Agency in respect of which it has not previously been
reimbursed by the holder (directly or as a result of the disposition of the
MetaSolv Common Shares as hereinbefore contemplated), MetaSolv AcquisitionCo and
the Corporation shall be entitled to withhold from any consideration payable to
such holder as contemplated herein all amounts sufficient to indemnify the
Corporation and MetaSolv AcquisitionCo for all of its costs of making such
advance.

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 Exchangeable Share Provisions, such holders shall not be
entitled to share in any further distribution of the assets of the Corporation.

5.4  MetaSolv AcquisitionCo shall have the overriding right (the "Liquidation
Call Right"), in the event of and notwithstanding the proposed liquidation,
dissolution or winding-up of the Corporation pursuant to this Article 5, to
purchase from all but not less than all of the holders of Exchangeable Shares on
the Liquidation Date all but not less than all of the Exchangeable Shares held
by each of such holders on payment by MetaSolv AcquisitionCo of an amount per
share equal to:

     (a)  the Current Market Price of a MetaSolv Common Share on the last
          Business Day prior to the Liquidation Date, which shall be satisfied
          in full by causing to be delivered to such holder one MetaSolv Common
          Share (subject to adjustment as provided for in Section 11.1), plus

     (b)  an additional amount equivalent to the full amount of all dividends
          declared and unpaid on such Exchangeable Share and all dividends
          declared on MetaSolv Common Shares which have not been declared on
          such Exchangeable Shares in accordance with Section 3.1 of these share
          provisions

(collectively the "Liquidation Call Purchase Price", provided that if the record
date for any such declared and unpaid dividends occurs  after the Liquidation
Date, the Liquidation Call Purchase Price shall not include such additional
amount equivalent to such dividends). In the event of the exercise of the
Liquidation Call Right by MetaSolv AcquisitionCo, each holder shall be obligated
to sell all the Exchangeable Shares held by the holder to MetaSolv AcquisitionCo
on the Liquidation Date on payment by MetaSolv AcquisitionCo to the holder of
the Liquidation Call Purchase Price for each such share.

5.5  To exercise the Liquidation Call Right, MetaSolv AcquisitionCo must notify
the holders of Exchangeable Shares and the Corporation of MetaSolv
AcquisitionCo's intention to exercise such right at least 30 days before the
Liquidation Date in the case of a voluntary liquidation, dissolution or
<PAGE>

                                      -12-

winding-up of the Corporation and at least five Business Days before the
Liquidation Date in the case of an involuntary liquidation, dissolution or
winding-up of the Corporation. If MetaSolv AcquisitionCo exercises the
Liquidation Call Right, on the Liquidation Date, MetaSolv AcquisitionCo 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.

5.6  For the purposes of completing the purchase of the Exchangeable Shares
pursuant to the Liquidation Call Right, MetaSolv AcquisitionCo shall deposit
with the Corporation, on or before the Liquidation Date, certificates
representing the aggregate number of MetaSolv Common Shares deliverable by
MetaSolv AcquisitionCo in payment of the total Liquidation Call Purchase Price
and a cheque or cheques in the amount of the remaining portion, if any, of the
total Liquidation Call Purchase Price. Provided that the total Liquidation Call
Purchase Price has been so deposited with the Corporation, on and after the
Liquidation Date the rights of each holder of Exchangeable Shares will be
limited to receiving such holder's proportionate part of the total Liquidation
Call Purchase Price payable by MetaSolv AcquisitionCo 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 MetaSolv Common
Shares delivered to it. Upon surrender to the Corporation 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 Act  and the Articles of Association of the
Corporation and such additional documents and instruments as the Corporation may
reasonably require (including, without limitation, a statutory declaration as to
the holder being a resident of Canada for the purposes of the Tax Act or a
certificate issued under section 116 of the Tax Act in form and substance, and
with a certificate limit, acceptable to the Corporation, failing which statutory
withholdings and remittances to the appropriate taxing authorities shall be made
upon the expiry of the applicable periods as contemplated in Section 5.2), the
holder of such surrendered certificate or certificates shall be entitled to
receive in exchange therefor, and the Corporation on behalf of MetaSolv
AcquisitionCo shall deliver to such holder, certificates representing the
MetaSolv Common Shares to which the holder is entitled and a cheque or cheques
of MetaSolv AcquisitionCo payable at par and in Canadian dollars at any branch
of the bankers of MetaSolv AcquisitionCo or of the Corporation in Canada in
payment of the remaining portion, if any, of the total Liquidation Call Purchase
Price. If  MetaSolv AcquisitionCo 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 price otherwise payable by the Corporation in connection with the
liquidation, dissolution or winding-up of the Corporation pursuant to this
Article 5.

          Business Day prior to the Retraction Date, which shall be satisfied in
          full by the Corporation causing to be delivered to such holder one
          MetaSolv Common Share (subject to adjustment as provided for in
          Section 11.1) for each Exchangeable Share presented and surrendered by
          the holder, plus

     (b)  an additional amount equivalent to the full amount of all dividends
          declared and unpaid thereon and all dividends declared on MetaSolv
          Common Shares which have not been declared on such Exchangeable Shares
          in accordance with Section 3.1 of these  share provisions

(collectively the "Retraction Price", provided that if the record date for any
such declared and unpaid dividends occurs  after the Retraction Date the
Retraction Price shall not include such additional amount equivalent to such
dividends).

To effect such redemption, the holder shall present and surrender at the
registered office of the Corporation or at such other address as may be
specified by the Corporation by notice to the holders of the 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 Act and the Articles of Association of the
Corporation and such additional documents and instruments as the Corporation may
reasonably require (including, without limitation, a statutory declaration as to
the holder being a resident of Canada for the purposes of the Tax Act or a
certificate issued under section 116 of the Tax Act in form and substance, and
with a certificate limit, acceptable to the Corporation, failing which statutory
withholding and remittances to the appropriate taxing authorities shall be made
upon the expiry of the period at which time the funds are required to be
remitted to the Canada Customs and Revenue Agency), 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:

     (c)  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;

     (d)  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
<PAGE>

                                      -14-

          be not less than five Business Days nor more than ten 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 fifth Business Day after the
          date on which the Retraction Request is received by the Corporation;
          and

     (e)  acknowledging the overriding right (the "Retraction Call Right") of
          MetaSolv AcquisitionCo 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 MetaSolv AcquisitionCo in accordance with the
          Retraction Call Right on the terms and conditions set out in Section
          6.3 below.

No transfer of any shares of the Corporation may be effected without the prior
written consent of the Corporation. In the event that, on or prior to the
Automatic Redemption Date, any holder of Exchangeable Shares notifies the
Corporation that such holder desires to:

     (f)  transfer or otherwise attempts to transfer any such shares to any
          other person or entity; or

     (g)  vote against or dissent from, or not send in a proxy (if the failure
          to send in such proxy results in a failure to establish a quorum for
          such meeting) in respect of any resolution proposed in respect of, any
          matter in accordance with the provisions of the Act or any
          corresponding provisions of any other corporate legislation under
          which the Corporation exists from time to time other than a matter
          which would result in an adverse affect on the attributes of the
          Exchangeable Shares unless such matter is required to maintain the
          equivalence of the Exchangeable Shares and the MetaSolv Common Shares;

(any such notification or attempt, a "Transfer/Dissent Attempt"), then in each
such case such holder shall, by such action, be deemed to have made a Retraction
Request on the following terms and conditions:

     (h)  the Exchangeable Shares which are the subject of such Transfer/Dissent
          Attempt (the "Transferred/Dissented Shares" shall be considered to be
          Retracted Shares for the purposes of such deemed Retraction Request;

     (i)  the Retraction Date shall be one Business Day after the date of
          receipt by the Corporation of notice of the Transfer/Dissent Attempt
          (or such lesser period as the Corporation may permit); and

     (j)  the holder shall be deemed to have acknowledged the overriding
          Redemption Call Right and the Retraction Call Right.
<PAGE>

                                      -15-

In accordance with the deemed Retraction Request, no certificates shall be
issued by the Corporation representing the Transferred/Dissented Shares in the
name of the transferee, and the sole right of the transferee in respect of the
Transferred/Dissented Shares shall be to receive the MetaSolv Common Shares to
which such person is entitled as a result of the Retraction Request.
Notwithstanding anything contained in this Article 6, no Retraction Request may
be submitted, and no Exchangeable Shares may be considered to be Retracted
Shares, without the written consent of the Corporation prior to the date on
which the Relief is obtained.

6.2  Subject to the exercise by MetaSolv AcquisitionCo of the Retraction Call
Right, upon receipt by the Corporation in the manner specified in Section 6.1
hereof of a certificate or certificates representing the number of Exchangeable
Shares which the holder desires to have the Corporation redeem, together with a
Retraction Request, and provided that the Retraction Request is not revoked by
the holder in the manner specified in Section 6.7 hereof, the Corporation shall
redeem the Retracted Shares effective at the close of business on the Retraction
Date and shall cause to be delivered to such holder the total Retraction Price
with respect to such shares. If only a part of the Exchangeable Shares
represented by any certificate are redeemed (or purchased by MetaSolv
AcquisitionCo 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 MetaSolv AcquisitionCo thereof. In order to exercise
the Retraction Call Right, MetaSolv AcquisitionCo must notify the Corporation in
writing of MetaSolv AcquisitionCo's determination to do so (the "MetaSolv
AcquisitionCo Call Notice") within four Business Days of notification to
MetaSolv AcquisitionCo by the Corporation of the receipt by the Corporation of
the Retraction Request. If MetaSolv AcquisitionCo does not so notify the
Corporation within such four Business Day period, the Corporation will notify
the holder as soon as possible thereafter that MetaSolv AcquisitionCo will not
exercise the Retraction Call Right. If MetaSolv AcquisitionCo delivers the
MetaSolv AcquisitionCo Call Notice within such four Business Day time 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
MetaSolv AcquisitionCo in accordance with the Retraction Call Right. In such
event, the Corporation shall not redeem the Retracted Shares and MetaSolv
AcquisitionCo shall purchase from such holder and such holder shall sell to
MetaSolv AcquisitionCo on the Retraction Date, the Retracted Shares for a
purchase price (the "Purchase Price") per share equal to the Retraction Price
per share plus, on the designated payment date therefor, to the extent not paid
by the Corporation on the designated payment date therefor, 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 and all dividends declared on MetaSolv Common
Shares which have not been declared on such Exchangeable Shares in accordance
with Section 3.1 of these share provisions (the "Dividend Amount").  For the
purposes of completing a purchase pursuant to the Retraction Call Right,
MetaSolv AcquisitionCo shall
<PAGE>

                                      -16-

deposit with the Corporation, on or before the Retraction Date, certificates
representing MetaSolv Common Shares and a cheque or cheques of MetaSolv
AcquisitionCo representing the aggregate Dividend Amount, less any amounts
withheld on account of tax required to be deducted and withheld therefrom and
the remaining portion, if any, of the total Purchase Price. Provided that the
total Purchase Price has been so deposited with the Corporation, 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 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
MetaSolv AcquisitionCo does not deliver a MetaSolv AcquisitionCo Call Notice
within such four 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 in the
manner otherwise contemplated in this Article 6.

6.4  The Corporation or MetaSolv AcquisitionCo, as the case may be, shall
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 such other
address as may be specified by the Corporation by notice to the holders of the
Exchangeable Shares, certificates representing the MetaSolv 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 in payment of the total
Retraction Price or the total Purchase Price, as the case may be, and a cheque
of the Corporation payable at par at any branch of the bankers of the
Corporation, or MetaSolv AcquisitionCo, as applicable, in payment of the
remaining portion, if any, of the total Retraction Price (less any tax required
to be deducted and withheld therefrom by the Corporation) or a cheque of
MetaSolv AcquisitionCo payable at par and in Canadian dollars at any branch of
the bankers of MetaSolv AcquisitionCo or of the Corporation in Canada in payment
of the remaining portion, if any, of the total Purchase Price, as the case may
be, and such delivery of such certificates and cheque on behalf of the
Corporation or by MetaSolv AcquisitionCo, as the case may be 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 cheque (less any tax
required and in fact deducted and withheld therefrom and remitted to the proper
tax authority), unless such cheque is not paid on due presentation. To the
extent that the amount of tax required to be deducted or withheld from any
payment to a holder of Exchangeable Shares exceeds the cash portion of such
payment,  the Corporation or MetaSolv AcquisitionCo, as the case may be, is
hereby authorized to sell or otherwise dispose of at fair market value such
portion of the property then payable to the holder as is necessary to provide
sufficient funds to the Corporation or MetaSolv AcquisitionCo, after payment of
any costs or expenses of such sale, in order to enable it to comply with such
deduction or withholding requirement and shall give an accounting to the holder
with respect thereto and any balance of such proceeds of sale.  If, in
connection with such exchange, MetaSolv AcquisitionCo or the Corporation is
required to advance funds on its own account to the Canada Customs and Revenue
Agency in respect of which it has not previously been reimbursed by the holder
(directly or as a result of the
<PAGE>

                                      -17-

disposition of the MetaSolv Common Shares as hereinbefore contemplated),
MetaSolv AcquisitionCo and the Corporation shall be entitled to withhold from
any consideration payable to such holder as contemplated herein all amounts
sufficient to indemnify the Corporation and MetaSolv AcquisitionCo for all of
its costs of making such advance.

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, 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 MetaSolv AcquisitionCo shall
thereafter be considered and deemed for all purposes to be a holder of the
MetaSolv Common Shares delivered to it. To the extent that the Corporation  or
MetaSolv AcquisitionCo has sold the property payable to the holder as
contemplated herein, the Corporation and MetaSolv AcquisitionCo shall be
entitled to withhold such portion of the consideration to which such non-
resident shareholder would otherwise be entitled until such time as the holder
provides to the Corporation and MetaSolv AcquisitionCo an appropriate
certificate issued under section 116 of the Tax Act or an equivalent amount in
cash or certified funds in an amount equal to the amount the Corporation and
MetaSolv AcquisitionCo is required to remit to the Canada Customs and Revenue
Agency on behalf of the non-resident shareholder if such a certificate is not
provided, and the Corporation and MetaSolv AcquisitionCo shall be entitled to
remit said amount to said Agency on behalf of the holder upon the expiry of the
applicable period at which time the funds are required to be remitted to the
Agency. The Corporation and MetaSolv AcquisitionCo shall also be entitled to
withhold from such consideration an amount sufficient to indemnify the
Corporation and MetaSolv AcquisitionCo for all of its costs of disposing of the
MetaSolv Common Shares as hereinbefore contemplated.  If, in connection with
such exchange, MetaSolv AcquisitionCo or the Corporation is required to advance
funds on its own account to the Canada Customs and Revenue Agency in respect of
which it has not previously been reimbursed by the holder (directly or as a
result of the disposition of the MetaSolv Common Shares as hereinbefore
contemplated), MetaSolv AcquisitionCo and the Corporation shall be entitled to
withhold from any consideration payable to such holder as contemplated herein
all amounts sufficient to indemnify the Corporation and MetaSolv AcquisitionCo
for all of its costs of making such advance.

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
<PAGE>

                                      -18-

any of such provisions to redeem the Retracted Shares tendered for redemption
on such date, and provided that MetaSolv AcquisitionCo 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 hereof, 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 MetaSolv to purchase such Retracted Shares from such holder on the
Retraction Date or as soon as practicable thereafter on payment by MetaSolv to
such holder of the Purchase Price for each such Retracted Share, as more
specifically provided in the Exchange 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 MetaSolv AcquisitionCo shall be deemed to have been revoked.

6.8    Notwithstanding any other provision of this Article 6, the Corporation
shall not be required to redeem the Retracted Shares unless such holder has
provided to the Corporation either (i) a statutory declaration to the effect
that such shareholder is not a non-resident of Canada for the purposes of the
Tax Act and the applicable provisions of any provincial legislation or (ii) a
certificate issued by the Minister of National Revenue under section 116 of the
Tax Act (or any successor provision) and any provincial equivalent if required,
with a certificate limit not less than the fair market value of the Retracted
Shares, failing which statutory withholdings and remittances to the appropriate
taxing authorities shall be made upon the expiry of the applicable periods as
contemplated in Section 6.5.

                                   ARTICLE 7

               REDEMPTION OF EXCHANGEABLE SHARES BY CORPORATION

7.1  Subject to applicable law, and subject to the exercise by MetaSolv
AcquisitionCo of the Redemption Call Right, the Corporation shall on the
Automatic Redemption Date redeem (the
<PAGE>

                                      -19-

"Automatic Redemption") all of the then outstanding Exchangeable Shares for an
amount per share equal to:

     (i)  the Current Market Price of a MetaSolv Common Share on the last
          Business Day prior to the Automatic Redemption Date, which shall be
          satisfied in full by the Corporation causing to be delivered to each
          holder of Exchangeable Shares one MetaSolv Common Share (subject to
          adjustment as provided for in Section 11.1) for each Exchangeable
          Share held by such holder, plus

     (ii) an additional amount equivalent to the full amount of all declared
          and unpaid dividends thereon and all dividends declared on MetaSolv
          Common Shares which have not been declared on such Exchangeable Shares
          in accordance with Section 3.1 of these share provisions

(collectively the "Redemption Price", provided that if the record date for any
such declared and unpaid dividends occurs  after the Automatic Redemption Date,
the Redemption Price shall not include such additional amount equivalent to such
dividends). If any Exchangeable Shares are issued after the Automatic Redemption
Date, the Corporation may immediately redeem such Exchangeable Shares as if they
were issued and outstanding on the Automatic Redemption Date.

7.2  In any case of a redemption of Exchangeable Shares under this Article 7,
the Corporation shall, at least 30 days before the date on which the
Exchangeable Shares are to be redeemed (the "Redemption Date") (other than a
redemption as a result of an Automatic Redemption Date established in connection
with a MetaSolv Control Transaction or an Exchangeable Share Voting Event, in
which case the notice shall not be less than 10 days) send or cause to be sent
to each holder of Exchangeable Shares to be redeemed a notice in writing of the
redemption by the Corporation or the purchase by MetaSolv AcquisitionCo 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
a MetaSolv Control Transaction or an Exchangeable Share Voting Event, the
written notice of redemption by the Corporation 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 to be reasonably practicable in the circumstances. Such
notice shall set out the formula for determining the Redemption Price or the
Redemption Call Purchase Price, as the case may be, the Automatic Redemption
Date and, if applicable, particulars of the Redemption Call Right. On or after
the Automatic Redemption Date and subject to the exercise by MetaSolv
AcquisitionCo 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 (less any tax required to be deducted and withheld therefrom by
the Corporation) for each such Exchangeable Share, upon presentation and
surrender at the registered office of the Corporation or at such other address
as may be specified by the Corporation by notice to the holders of the
Exchangeable Shares, of the certificates representing such Exchangeable Shares,
together with such other documents and instruments as may be required
<PAGE>

                                      -20-

to effect a transfer of Exchangeable Shares under the Act and the Articles of
Association of the Corporation and such additional documents and instruments as
the Corporation may reasonably require (including, without limitation, a
statutory declaration as to the holder being a resident of Canada for the
purposes of the Tax Act or a certificate issued under section 116 of the Tax Act
and any provincial equivalent if required in form and substance, and with a
certificate limit, acceptable to the Corporation, subject to the last sentence
of this Section 7.2). Payment of the total Redemption Price for such
Exchangeable Shares 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 such
other address as may be specified by the Corporation by notice to the holders of
the Exchangeable Shares, of certificates representing MetaSolv 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 and, if applicable, a cheque of the Corporation payable at par at any
branch of the bankers of the Corporation in respect of the additional amount
equivalent to the full amount of all declared and unpaid dividends and all
dividends declared on MetaSolv Common Shares which have not been declared on
such Exchangeable Shares in accordance with Section 3.1 of these share
provisions comprising part of the total Redemption Price (less any tax required
to be deducted and withheld therefrom by the Corporation). On and after the
Automatic 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 holders in respect thereof, other
than the right to receive their proportionate part of the total Redemption
Price, unless payment of the total Redemption Price 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 has 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 Exchangeable Shares as
aforesaid to deposit or cause to be deposited the total Redemption Price of the
Exchangeable Shares so called for redemption, or of 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. Upon the later of such deposit being made and the
Automatic 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 Automatic Redemption Date, as the case may be,
shall be limited to receiving their proportionate part of the total Redemption
Price (less any tax required to be deducted and withheld therefrom by the
Corporation) 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, the holders of the Exchangeable Shares shall thereafter be
considered and deemed for all purposes to be holders of the MetaSolv Common
Shares delivered to them. To the extent that the amount of tax required to be
deducted or withheld from any payment to a holder of Exchangeable Shares exceeds
the cash portion of such payment, the Corporation and MetaSolv Acquisition Co is
hereby authorized to sell or otherwise dispose of at fair market value such
portion of the property then payable to the holder as is necessary to provide
<PAGE>

                                      -21-

sufficient funds to the Corporation and MetaSolv AcquisitionCo, after payment of
any costs or expenses of such sale, in order to enable it to comply with such
deduction or withholding requirement and shall give an accounting to the holder
with respect thereto and any balance of such proceeds of sale. To the extent
that the Corporation  or MetaSolv AcquisitionCo has sold the property payable to
the holder as contemplated herein, the Corporation and MetaSolv AcquisitionCo
shall be entitled to withhold such portion of the consideration to which such
non-resident shareholder would otherwise be entitled until such time as the
holder provides to the Corporation and MetaSolv AcquisitionCo an appropriate
certificate issued under section 116 of the Tax Act and any provincial
equivalent or an equivalent amount in cash or certified funds in an amount equal
to the amount the Corporation and MetaSolv AcquisitionCo is required to remit to
the Canada Customs and Revenue Agency on behalf of the non-resident shareholder
if such a certificate is not provided, and the Corporation and MetaSolv
AcquisitionCo shall be entitled to remit said amount to said Agency on behalf of
the holder upon the expiry of the applicable period at which time the funds are
required to be remitted to the Agency. The Corporation and MetaSolv
AcquisitionCo shall also be entitled to withhold from such consideration an
amount sufficient to indemnify the Corporation and MetaSolv AcquisitionCo for
all of its costs of disposing of the MetaSolv Common Shares as hereinbefore
contemplated.   If, in connection with such exchange, MetaSolv AcquisitionCo or
the Corporation is required to advance funds on its own account to the Canada
Customs and Revenue Agency in respect of which it has not previously been
reimbursed by the holder (directly or as a result of the disposition of the
MetaSolv Common Shares as hereinbefore contemplated), MetaSolv AcquisitionCo and
the Corporation shall be entitled to withhold from any consideration payable to
such holder as contemplated herein all amounts sufficient to indemnify the
Corporation and MetaSolv AcquisitionCo for all of its costs of making such
advance.

7.3  MetaSolv AcquisitionCo shall have the overriding right (the "Redemption
Call Right"), notwithstanding the proposed redemption of Exchangeable Shares by
the Corporation pursuant to this Article 7 of these share provisions, to
purchase from all but not less than all of the holders of Exchangeable Shares to
be redeemed on the Automatic Redemption Date, all but not less than all of the
Exchangeable Shares held by each such holder on payment by MetaSolv
AcquisitionCo to the holder of an amount per share equal to:

     (a)  the Current Market Price of a MetaSolv Common Share on the last
          Business Day prior to the Automatic Redemption Date which shall be
          satisfied in full by causing to be delivered to such holder one
          MetaSolv Common Share (subject to adjustment as provided for in
          Section 11.1), plus

     (b)  an additional amount equivalent to the full amount of all dividends
          declared and unpaid on such Exchangeable Share and all dividends
          declared on MetaSolv Common Shares which have not been declared on
          such Exchangeable Shares in accordance with Section 3.1 of these share
          provisions
<PAGE>

                                      -22-

(collectively the "Redemption Call Purchase Price", provided that if the record
date for any such declared and unpaid dividends occurs  after the Automatic
Redemption Date, the Redemption Call Purchase Price shall not include such
additional amount equivalent to such dividends). In the event of the exercise of
the Redemption Call Right by MetaSolv AcquisitionCo, each holder shall be
obligated to sell all the Exchangeable Shares held by the holder and otherwise
to be redeemed to MetaSolv AcquisitionCo on the Automatic Redemption Date on
payment by MetaSolv AcquisitionCo to the holder of the Redemption Call Purchase
Price for each such share.

7.4  To exercise the Redemption Call Right, MetaSolv AcquisitionCo must notify
the holders of Exchangeable Shares, and the Corporation of MetaSolv
AcquisitionCo's intention to exercise such right at least 30 days before the
Automatic Redemption Date (or, in the case of a Redemption Date established in
connection with a MetaSolv Control Transaction or an Exchangeable Share Voting
Event, at least 10 days).  The Corporation will notify the holders of the
Exchangeable Shares as to whether or not MetaSolv AcquisitionCo has exercised
the Redemption Call Right forthwith after the expiry of the period during which
the same may be exercised by MetaSolv AcquisitionCo.  If MetaSolv AcquisitionCo
exercises the Redemption Call Right, on the Automatic Redemption Date, MetaSolv
AcquisitionCo will purchase and the holders will sell all of the Exchangeable
Shares to be redeemed for a price per share equal to the Redemption Call
Purchase Price.

7.5  For the purposes of completing the purchase of Exchangeable Shares pursuant
to the Redemption Call Right, MetaSolv AcquisitionCo shall deposit with the
Corporation, on or before the Automatic Redemption Date, certificates
representing the aggregate number of MetaSolv Common Shares deliverable by
MetaSolv AcquisitionCo in payment of the total Redemption Call Purchase Price
and a cheque or cheques in the amount of the remaining portion, if any, of the
total Redemption Call Purchase Price. Provided that the total Redemption Call
Purchase Price has been so deposited with the Corporation, on and after the
Automatic Redemption Date the rights of each holder of Exchangeable Shares so
purchased will be limited to receiving such holder's proportionate part of the
total Redemption Call Purchase Price payable by MetaSolv AcquisitionCo upon
presentation and surrender by the holder of certificates representing the
Exchangeable Shares purchased by MetaSolv AcquisitionCo from such holder and the
holder shall on and after the Automatic Redemption Date be considered and deemed
for all purposes (including for purposes of dividend entitlement, if any) to be
the holder of the MetaSolv Common Shares delivered to such holder. Upon
surrender to the Corporation 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 Act and the
Articles of Association of the Corporation and such additional documents and
instruments as the Corporation may reasonably require (including, without
limitation, a statutory declaration as to the holder being a resident of Canada
for the purposes of the Tax Act or a certificate issued under section 116 of the
Tax Act in form and substance, and with a certificate limit, acceptable to the
Corporation, failing which statutory withholdings and remittances to the

                                      -23-

shall deliver to such holder, certificates representing the MetaSolv Common
Shares to which the holder is entitled and a cheque or cheques of MetaSolv
AcquisitionCo payable at par and in Canadian dollars at any branch of the
bankers of MetaSolv AcquisitionCo or of the Corporation in Canada in payment of

                                   ARTICLE 8

                           PURCHASE FOR CANCELLATION

8.1  Subject to applicable law and the Memorandum of Association and Articles of
Association 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 private agreement with one or more holders of
Exchangeable Shares or by tender to all the holders of record of Exchangeable
Shares then outstanding, at any price per share together with an amount equal to
all declared and unpaid dividends thereon. 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 only part of the Exchangeable Shares
represented by any certificate shall be purchased, a new certificate for the
balance of such shares shall be issued at the expense of the Corporation.
Notwithstanding the foregoing, the Corporation may at any time and from time to
time purchase Exchangeable Shares held by any of its Affiliates (including
MetaSolv AcquisitionCo) in exchange for Common Shares without making a similar
offer to all the holders of record of Exchangeable Shares then outstanding.

                                 VOTING RIGHTS

9.1  Except as required by applicable law and the provisions of 10.1, 11.1 and
12.2 and any Exchangeable Share Voting Event, the holders of the Exchangeable
Shares shall not be entitled as such to receive notice of or to attend any
meeting of the shareholders of the Corporation or to vote at
<PAGE>

                                      -24-

shall not have the right to vote separately as a class upon an amendment to the
Memorandum or Articles of Association of the Corporation to:

     (a)  increase or decrease any maximum number of authorized shares of such
          class, or increase any maximum number of authorized shares of a class
          having rights or privileges equal or superior to the shares of such
          class;

     (b)  effect an exchange, reclassification or cancellation of all or part of
          the shares of such class; or

     (c)  create a new class of shares equal or superior to the shares of such
          class;

unless such amendment constitutes an Exchangeable Share Voting Event.

of Exchangeable Shares duly called and held at which the holders of at least 25%

the outstanding Exchangeable Shares at that time are not present or represented
by proxy within one-half hour after the time appointed for such meeting then the
meeting shall be adjourned to such date not less than five days thereafter and

as is necessary to provide sufficient funds to the Corporation and MetaSolv
AcquisitionCo, after payment of any costs or expenses of such sale, in order to
enable them to comply with such deduction or withholding requirement and the
Corporation and MetaSolv AcquisitionCo shall give an accounting to the holder
with respect thereto and any balance of such proceeds of sale.
