     Hundred Fifty Million Dollars ($150,000,000.00). The Borrowing Base shall
     be re-determined semi-annually pursuant to the following provisions of this
     Section. On or before August 1, 2004, Borrower shall furnish to the
     Administrative Agent information sufficient to update to an effective date
     of June 1, 2004, the most recent Reserve Report provided to the
     Administrative Agent prior to Closing of the Third Amendment relative to
     the Proved Reserves attributable to the Borrowing Base Oil and Gas
     Properties. Upon receipt of such information, the Arrangers shall, in the
     normal course of business, make a joint determination of the Borrowing
     Base, which shall become effective upon approval by the Required Banks and
     subsequent written notification from the Administrative Agent to the
     Borrower, and which, subject to the other provisions of this Agreement,
     shall be the basis on which the Borrowing Base shall thereafter be
     calculated until the effective date of the next redetermination of the
     Borrowing Base as set forth in this Section. Thereafter, on or before each
     April 1 and October 1 until the Facility Termination Date, beginning April
     1, 2005, the Borrower shall furnish to the Administrative Agent a Reserve
     Report, in form and substance satisfactory to the Administrative Agent,
     which report shall set forth, as of each preceding January 1 or July 1, as

     Gas Properties. Each Reserve Report that is due to be submitted to the
     Administrative Agent on or before each April 1 shall be a complete report
     prepared by an independent petroleum engineer or firm of engineers
     acceptable to Administrative Agent, and each Reserve Report due to be
     submitted on or before October 1 or each year shall be prepared under the
     supervision of the chief petroleum engineer of Borrower and shall simply
     update, to its effective date, the last complete Reserve Report provided to
     Administrative Agent. Upon receipt of each such Reserve Report, the
     Arrangers shall, in the normal course of business, make a joint
     determination of the Borrowing Base which shall become effective upon
     approval by the Required Banks and subsequent written notification from the
     Administrative Agent to the Borrower, and which, subject to the other
     provisions of this Agreement, shall be the basis on which the Borrowing
     Base shall thereafter be calculated until the effective date of the next
     redetermination of the Borrowing Base as set forth in this Section 2.06.
     The Arrangers may, subject to approval of the Required Banks, and must,
     upon the request of the Required Banks, redetermine the Borrowing Base at
     any time, and from time to time, which redetermination shall become
     effective upon approval by the Required Banks and subsequent written
     notification from the Administrative Agent to the Borrower and which,
     subject to the other provisions of this Agreement, shall be the basis on
     which the Borrowing Base shall thereafter be calculated until the effective
     date of the next redetermination of the Borrowing Base, as set forth in
     this Section. Not more often than two times in any calendar year, the
     Administrative Agent may request in writing that the Borrower provide a
     Reserve Report regarding the Proved Reserves attributable to the Borrowing
     Base Oil and Gas Properties with an effective date not more than ninety
     (90) days prior to Borrower's delivery of such Reserve Report to
     Administrative Agent, and such Reserve Report shall be delivered to
     Administrative Agent within ninety (90) days after Borrower's receipt of
     such written request.

     Section 2.09, Prepayment and Conversion, is amended and restated in its
entirety to read as follows:

     2.09 Prepayment and Conversion.

          (a)  Tranche A Loans. Upon the Required Number of days written notice
               to the Administrative Agent, the Borrower may, without the
               payment of penalty or premium, prepay the principal of the
               Tranche A Loans or voluntarily convert the applicable Floating
               Rate of any Tranche A Loan prior to the termination of the
               applicable Interest Period in whole or in part, from time to
               time. Any partial payment or conversion of RR Loans shall be made
               in the sum of not less than $1,000,000, and any partial payment
               or conversion of LIBOR Loans shall be made in the sum of not less
               than $1,000,000 or any $1,000,000 increment in addition thereto.
               With respect to any such prepayment or conversion of any LIBOR
               Loan the Borrower agrees to pay to the Banks upon the request of
               the Administrative Agent such amount or amounts as will
               compensate the Banks for Breakage Costs, excluding, however, any
               such Breakage Costs resulting from a payment or prepayment made
               more than sixty (60) days prior to the Administrative Agent's
               request for payment of Breakage Costs. The payment of any such
               Breakage Costs to the Banks shall be made within thirty (30) days
               of a request therefor from Administrative Agent. If LIBOR cannot
               be determined on the date of such prepayment, the Administrative
               Agent shall calculate LIBOR by interpolating LIBOR in effect
               immediately prior to the prepayment and LIBOR in effect
               immediately after the prepayment.

          (b)  Tranche B Loan. No prepayments of any portion of the outstanding
               balance of the Tranche B Loan shall be permitted prior to April
               1, 2005. On and after April 1, 2005, the Tranche B Loan may be
               prepaid, in whole or in part, subject to satisfaction of the
               following conditions: (i) such prepayment must be made using
               proceeds drawn by Borrower as a Tranche A Loan, (ii) immediately
               following such prepayment, the Aggregate Outstanding Credit
               Exposure, minus the Tranche B Limit, shall not exceed ninety
               percent (90%) of the Borrowing Base then in effect, and (iii)
               contemporaneously with such prepayment, Borrower shall pay to
               Administrative Agent, for further credit to all the Banks in
               proportion to their respective Percentage Shares, a refinancing
               fee in an amount equal to one percent (1%) of the amount of such
               prepayment.

     Article IV, Representations and Warranties, is amended by adding the
following new Section 4.24 thereto:

     4.24 Solvency. As of the date of the Third Amendment, and after giving
     effect to the Tranche B Loan advanced at the Closing of the Third Amendment
     and the Obligations of Borrower under the Loan Documents, Borrower: (a) is,
     and will be, solvent, (b) has and will have assets and property that,
     fairly valued, exceed its aggregate liabilities, obligations and debts
     (both fixed and contingent), (c) is and will continue to be able to
     satisfy, pay and discharge its liabilities, obligations and debts as they
     become due, and (d) has and will continue to have sufficient capital to
     carry on in the ordinary course the business in which it is engaged.

the following text thereof: "together with the report and opinion thereon of
Arthur Andersen LLP or such other firm of independent certified public
accountants acceptable to the Administrative Agent at its reasonable

     certified public accountants selected by Borrower and acceptable to the
     Required Banks in their reasonable discretion.

     Section 5.18, Borrowing Base, is amended by adding thereto the following
text at the end of such Section:

     In addition, Borrower shall at all times: (a) cause its Borrowing Base Oil

     Bank that has become a party to the Credit Agreement pursuant to this Third
     Amendment and each Bank whose Percentage Share increased as the result of
     this Third Amendment shall thereafter be deemed to have been a "Purchasing
     Bank" as set forth in Section 9.05(c); provided that the Outgoing Banks, as
     assigning Banks, shall have no obligation to pay an assignment fee as set
     forth in Section 9.05(c).

     IV. Reaffirmation of Representations and Warranties. To induce the Banks to
enter into this Third Amendment, the Borrower hereby reaffirms, as of the date
hereof, its representations and warranties contained in Article IV of the Credit
Agreement and in all other documents executed pursuant thereto, and additionally
represents and warrants as follows:

     A. The execution and delivery of this Third Amendment and the performance
     by the Borrower of its obligations under this Third Amendment are within
     the Borrower's power, have been duly authorized by all necessary corporate
     action, have received all necessary governmental approval (if any shall be
     required), and do not and will not contravene or conflict with any
     provision of law or of the charter or by-laws of the Borrower or of any
     agreement binding upon the Borrower.

     B. The Credit Agreement as amended by this Third Amendment represents the
     legal, valid and binding obligations of the Borrower, enforceable against
     the Borrower in accordance with their respective terms subject as to
     enforcement only to bankruptcy, insolvency, reorganization, moratorium or
     other similar laws affecting the enforcement of creditors' rights
     generally.

     C. No Event of Default or Unmatured Event of Default has occurred and is
     continuing as of the date hereof.

     D. Since the date of the Agreement, Borrower has not formed or created any
     new Subsidiaries.

     V. Defined Terms. Except as amended hereby, terms used herein that are
defined in the Credit Agreement shall have the same meanings herein.

     VI. Reaffirmation of Credit Agreement. This Third Amendment shall be deemed
to be an amendment to the Credit Agreement, and the Credit Agreement, as further
amended hereby, is hereby ratified, approved and confirmed in each and every
respect. All references to the Credit Agreement herein and in any other
document, instrument, agreement or writing shall hereafter be deemed to refer to
the Credit Agreement as amended hereby.

     VII. Entire Agreement. The Credit Agreement, as hereby amended, embodies
the entire agreement between the Borrower and the Banks and supersedes all prior
proposals, agreements and understandings relating to the subject matter hereof.
The Borrower certifies that it is relying on no representation, warranty,
covenant or agreement except for those set forth in the Credit Agreement, as
hereby amended, and in the other documents previously executed or executed of
even date herewith.

     VIII. Governing Law. THIS THIRD AMENDMENT SHALL BE GOVERNED BY AND
CONSTRUED IN ACCORDANCE WITH THE LAWS OF THE STATE OF TEXAS AND THE APPLICABLE
LAWS OF THE UNITED STATES OF AMERICA. This Third Amendment has been entered into
in Harris County, Texas, and it shall be performable for all purposes in Harris
County, Texas. Courts within the State of Texas shall have jurisdiction over any
and all disputes between the Borrower and the Banks, whether in law or equity,
including, but not limited to, any and all disputes arising out of or relating
to this Third Amendment or any other Security Instrument; and venue in any such
dispute whether in federal or state court shall be laid in Harris County, Texas.

     IX. Severability. Whenever possible each provision of this Third Amendment
shall be interpreted in such manner as to be effective and valid under
applicable law, but if any provision of this Third Amendment shall be prohibited
by or invalid under applicable law, such provision shall be ineffective to the
extent of such prohibition or invalidity, without invalidating the remainder of
such provision or the remaining provisions of this Third Amendment.

     X. Execution in Counterparts. This Third Amendment may be executed in any
number of counterparts and by the different parties on separate counterparts,
and each such counterpart shall be deemed to be an original, but all such
counterparts shall together constitute but one and the same agreement.

     XI. Section Captions. Section captions used in this Third Amendment are for
convenience of reference only, and shall not affect the construction of this
Third Amendment.

     XII. Successors and Assigns. This Third Amendment shall be binding upon the
Borrower and the Banks and their respective successors and assigns, and shall
inure to the benefit of the Borrower and the Banks, and the respective
successors and assigns of the Banks.

     XIII. Non-Application of Chapter 346 of Texas Finance Codes. In no event
shall Chapter 346 of the Texas Finance Code (which regulates certain revolving
loan accounts and revolving tri-party accounts) apply to this Credit Agreement
as hereby further amended or any other Loan Documents or the transactions
contemplated hereby.

     XIV. Notice. THIS THIRD AMENDMENT TOGETHER WITH THE LOAN AGREEMENT, AND THE
OTHER SECURITY INSTRUMENTS REPRESENT THE FINAL AGREEMENT BETWEEN THE PARTIES AND
MAY NOT BE CONTRADICTED BY EVIDENCE OF PRIOR, CONTEMPORANEOUS OR SUBSEQUENT ORAL
AGREEMENTS OF THE PARTIES. THERE ARE NO WRITTEN ORAL AGREEMENTS BETWEEN THE

fact required to be stated therein or necessary to make the statements contained

          (d) Each of Company and its Subsidiaries is duly qualified or licensed
as a foreign corporation to do business as a foreign corporation, and is in good

leased or  operated  by it or the  nature of its of its  activities  makes  such
qualification  or licensing  necessary,  except for such  failures to be so duly
qualified or licensed and in good standing that would not be reasonably expected
to have a Material Adverse Effect on Company.

<PAGE>

               (i)  Company  has  provided  to  Parent  copies  of the  material
Employee Plans (and, if applicable, related trust agreements) and all amendments
thereto and written interpretations thereof together with the annual reports for

increases  or  decreases  in  benefits,  acceleration  of  payments  or  vesting
schedules or other  events  which would result in any material  liability to the
Company, and for the most recent plan years, if applicable, discrimination tests
for each material Employee Plan.

               (ii) Neither Company, its Subsidiaries nor any ERISA Affiliate of
Company or its  Subsidiaries  has (i) engaged  in, or is a  successor  or parent
corporation to an entity that has engaged in, a transaction described in Section

past 6  years,  maintained,  sponsored,  participated  in or  contributed  to, a
Pension  Plan which is subject to Title IV of ERISA or Section  412 of the Code.
There are no going concern unfunded actuarial liabilities, past service unfunded
liabilities or solvency deficiencies respecting any of the Employee Plans.

               (iii) Each Employee  Plan that is intended to be qualified  under

pending  or has  time  remaining  in  which to  file,  an  application  for such
determination from the Internal Revenue Service, and Company or its Subsidiaries

rules and  regulations,  including but not limited to ERISA and the Code,  which
are  applicable  to such  Employee  Plan,  except  that would not be  reasonably
expected to have, individually or in the aggregate, a Material Adverse Effect on

required to be remitted,  paid to or in respect of each  Employee Plan have been
paid or  remitted  in  accordance  with its terms  and all  Laws,  and no taxes,
penalties  or fees are owing  under any  Employee  Plan.  With  respect  to each

terminated or otherwise  discontinued  after the Closing Date in accordance with
its terms, and such actions will not, either alone or in the

                                      -22-

Company or any  Subsidiary.

               (iv)  Since  December  31,  2002,  there  have  been no  material
increases or changes to, the benefits provided under any Employee Plan.  Company
does not have  any  plan or  commitment  (including  any  verbal  indication  or
commitment  made  to  any  one  or  more  employees  of  Company  or  any of its
Subsidiaries  or to the  employees  of  Company  or any of its  Subsidiaries  in
general) to establish any new Employee Plan, to modify any Employee Plan (except
to the extent  required by the terms of any existing  Employee Plan or by Law or
to conform any such Employee Plan to the  requirements of any Laws, in each case
as previously disclosed to Parent in writing, or as required by this Agreement),
or to enter into any new Employee  Plan.

               (v) Neither the execution and delivery of this  Agreement nor the
consummation  of the  transactions  contemplated  hereby  will (i) result in any
payment (including severance, unemployment compensation, golden parachute, bonus
or  otherwise,   whether  due  upon  voluntary  or  involuntary  termination  or
otherwise) becoming due to any employee,  independent  contractor or director of
Company or any Subsidiary under any Employee Plan or otherwise,  (ii) materially

agreement,  plan,  arrangement or other contract  covering any current or former
employee,  independent  contractor  or  director  of the  Company  or any of its
Subsidiaries that, considered  individually or considered  collectively with any
other such agreements, plans, arrangements or other contracts, will, or would be
reasonably  expected to, give rise  directly or indirectly to the payment of any
amount that would be characterized as an "excess  parachute  payment" within the
meaning of Sections 280G(b)(1), 404 or 162(m) of the Code. There is no contract,
agreement,  plan or arrangement to which Company or any of its Subsidiaries is a
party or by which Company or any of its  Subsidiaries is bound to compensate any
individual  for excise  taxes paid  pursuant  to Section  4999 of the Code.  The
Company Schedule attached hereto sets forth all Employment Contracts,  severance
agreements,  gross-ups  and option  agreements,  if any,  for the 14 most highly
compensated  officers  of  Company  (in  terms of base  compensation),  true and
correct copies of which have been provided to Parent.  Neither the voluntary nor
involuntary  termination  of any  officer or  employee  of Company or any of its
Subsidiaries  following the Effective  Time will result in any payment  becoming
due to any such  employee  or officer of  Company or any such  Subsidiary.

               (vi) There is no material action, suit,  investigation,  audit or
proceeding  pending  against  or  involving  or, to the  knowledge  of  Company,
threatened against or involving any Employee Plan before any court or arbitrator
or any state, federal or local governmental body, agency or official (other than
routine Claims for benefits).

               (vii)  Neither  Company  nor  any of  its  Subsidiaries  has  any
material  current  or  projected  liability  in respect  of  post-employment  or
post-retirement health or medical or life insurance benefits for retired, former
or current employees of Company or its Subsidiaries, except as

                                      -23-

<PAGE>

required to avoid excise tax under  Section  4980B of the Code.  With respect to
each Employee Plan,  Company and each of its Subsidiaries have complied with (i)
the  applicable   health  care   continuation  and  notice   provisions  of  the
Consolidated  Omnibus  Budget  Reconciliation  Act of  1985  ("COBRA")  and  the
regulations  thereunder or any similar applicable state law, (ii) the applicable
requirements of the Health  Insurance  Portability  Amendments Act ("HIPAA") and
the regulations  thereunder and (iii) the applicable  requirements of the Family
Medical  Leave  Act of  1993  and  the  regulations  thereunder  or any  similar
applicable  state law,  except to the extent that such  failure to comply  would
not, in the aggregate, be reasonably expected to have a Material Adverse Effect.

               (viii) At no time  during  the past six years has  Company or its
Subsidiaries or any ERISA Affiliate of Company or its  Subsidiaries  contributed
to or been  requested to  contribute  to any  multiemployer  plan, as defined in
Section 3(37) of ERISA or any plan described in Section 413(c) of the Code.

               (ix) Each  International  Plan of Company or its Subsidiaries has
been  maintained in material  compliance  with its terms and  conditions  and in
material compliance with the requirements prescribed by any and all statutory or
regulatory  laws that are  applicable to such  International  Plan,  except that
would not,  individually or in the aggregate,  be reasonably  expected to have a
Material Adverse Effect on the Company.  There has been no amendment to, written
interpretation of or announcement  (whether or not written) by Company or any of
its  Subsidiaries  relating to, or change in employee  participation or coverage
under any  International  Plan that would  increase  materially  the  expense of
maintaining  such  International  Plan  above the level of expense  incurred  in
respect thereof for the end of the prior fiscal year.

     3.13 Labor Matters.
          -------------

          (a) There are no actions, suits, Claims,  proceedings,  labor disputes
or grievances pending,  or, to the knowledge of Company,  threatened relating to
any labor, health and safety,  workers'  compensation or discrimination  matters
involving any Employee,  including without  limitation,  charges of unfair labor
practices  or  discrimination  complaints.   Neither  Company  nor  any  of  its
Subsidiaries has engaged in any unfair labor practices within the meaning of the
National  Labor  Relations  Act or  any  foreign  equivalent.  Company  and  its
Subsidiaries  have not incurred any  liability  under,  and have complied in all
respects  with, the Worker  Adjustment  Retraining  Notification  Act (the "WARN
Act"),  and no fact or event exists that could give rise to liability  under the
WARN Act.

          (b) No Trade Union,  association of employees,  certified association,
council of trade unions,  employee  bargaining  agency or affiliated  bargaining
agent,  holds bargaining  rights with respect to any employees of Company or its
Subsidiaries  by  way  of  certification,   interim   certification,   voluntary
recognition, designation or successor rights.

          (c) Each of  Company  and its  Subsidiaries  is in  compliance  in all
material respects with all applicable  foreign,  federal,  state and local Laws,
rules and regulations  respecting  employment,  employment practices,  terms and

Employees,  and has withheld,  reported and remitted all amounts required

                                      -24-

by law or by  agreement to be  withheld,  reported and remitted  with respect to
wages, salaries and other payments to Employees.

          (d) The Benefits Schedule sets forth a complete list of the Collective
Agreements and listed  certifications or pending  certifications with respect to
Collective  Agreements  either  directly or by operation of Law,  with any Trade
Union or  association  which may qualify as a Trade Union.  Current and complete
copies of all  Collective  Agreements  have been made  available  to the Parent.
There  are no  outstanding  or,  to the  knowledge  of the  Company,  threatened
proceedings  which could result in  certification of a Trade Union as bargaining
agent for any Employees of the Company or any of the  Subsidiaries,  not already
covered by the Collective Agreements.  To the knowledge of Company, there are no
threatened or apparent union organizing  activities  involving  Employees of the
Company  or  any of the  Subsidiaries  not  already  covered  by the  Collective
Agreements.  Neither  the  Company  nor any of the  Subsidiaries  is in material
violation of any provision under any Collective Agreement. There is no strike or
lock out  occurring  or, to the  knowledge  of the Company,  threatened  strike,
lockout,  or other work stoppage or slowdown,  or other labor dispute  affecting
the Company or any of the Subsidiaries.

     3.14 Restrictions on Business Activities.
          -----------------------------------

     There is no agreement,  commitment,  judgment,  injunction, order or decree
binding  upon  Company  or its  Subsidiaries  or to which  Company or any of its
Subsidiaries  is a party which has or would be  reasonably  expected to have the
effect of (a)  prohibiting or impairing any business  practice of Company or any
of its Subsidiaries, (b) prohibiting or impairing any acquisition of property by
Company or any of its Subsidiaries,  (c) prohibiting or impairing the conduct of
business by Company or any of its  Subsidiaries  as  currently  conducted  or as
currently  planned  to be  conducted  or  (d)  requiring  Company  or any of its
Subsidiaries to conduct any portion of its business (including,  but not limited
to, the location of  facilities,  hiring of employees or the  purchase,  sale or
distribution of their products) in a specified geographical location.

     3.15 Title to Property.  Neither Company nor any of its Subsidiaries own or
have title to any real property. Section 3.14 of the Company Schedule sets forth
all leases,  subleases or other occupancy agreements (the "Leases") for the real
property  leased or  otherwise  occupied  by the  Company  and its  Subsidiaries
("Leased Real Property"). The Leases afford Company and/or its Subsidiaries,  as
the  case  may be,  peaceful  and  undisturbed  possession  of the  Leased  Real
Property,  except as would not be reasonably expected to have a Material Adverse
Effect on Company. All Leases for the Leased Real Property are, to the knowledge
of Company,  in good  standing,  valid and  effective in  accordance  with their
respective terms.  Except for breaches,  violations or defaults which would not,
individually  or in the  aggregate,  be  reasonably  expected to have a Material
Adverse Effect on Company,  neither Company nor any of its Subsidiaries,  nor to
Company's  knowledge  any  other  party  to any such  lease  or other  occupancy
agreement, is in breach, violation or default under, and neither Company nor any
of its Subsidiaries  has received written notice that it has breached,  violated
or defaulted under, any of the material terms or conditions of any such lease or
other occupancy agreement to which Company or any of its Subsidiaries is a party
or by which it is bound in such a manner  as would  permit  any  other  party to
cancel or terminate any such lease or other occupancy agreement, or would permit
any other party to seek damages or other remedies.

material  respects.

               (ii) Company and each of its  Subsidiaries  have timely paid,  or

Statements  in  connection  with the  operation  of its business in the ordinary
course.

               (iv)   There  is  no   material   claim   (including   under  any

               (v) There are no liens for Taxes  upon the  assets of  Company or
its  Subsidiaries  except for liens for current  Taxes not yet due.

               (vi) To the knowledge of Company,  neither Company nor any of its
Subsidiaries  is party  to or has any  obligation  under  any tax  sharing,  tax
indemnity or tax allocation  agreement or  arrangement  that could result in any
material Tax liability for Company or any of its Subsidiaries.

               (vii)  To the  knowledge  of  Company,  the  consummation  of the
transactions contemplated hereby will not in and of themselves (i) cause any Tax
to become  payable by the  Company or any of its  Subsidiaries  or (ii) have any
adverse effect on the continued  validity and  effectiveness of any material Tax
exemption, Tax holiday or other Tax reduction agreement or order applying to the
Company or any of its Subsidiaries.

entered into an agreement to extend the statute of limitations.  The Company has
not entered into any compensatory  agreements with respect to the performance of
services  which  payment  thereunder  would  result in a material  nondeductible
expense  pursuant to Section 280G of the Code or an excise tax to the  recipient
of such  payment  pursuant  to  Section  4999 of the  Code.

     3.17 Environmental Matters.

agreement or understanding  pursuant to which such Company Licensed Intellectual
Property is being  licensed  to or used by Company or any  Subsidiary  (each,  a
"License-In  Agreement").  The rights licensed under each  License-In  Agreement
shall be exercisable by Company, Parent or any subsidiary of Parent on and after
the  consummation of the Amalgamation to the same extent and at the same cost as
Company or such  Subsidiary,  as applicable,  prior to the  consummation  of the
Amalgamation  and no party  granting such rights has given formal written notice
to Company or, to Company's knowledge,  threatened, that it intends to terminate
such License-In Agreement prior to the expiration thereof in accordance with its
terms or not  extend or renew or allow  Company or any  Subsidiary  to extend or
renew such  License-In  Agreement.

          (c) Except for the agreements  set forth in Section  3.17(c)(i) of the
Company Schedule,  which subject the Company  Intellectual  Property to security
interests obtained in the ordinary course of business, (i) Company or one of its
Subsidiaries is the exclusive  owner of the entire right,  title and interest in
and to each item of the Company Owned Intellectual  Property,  including without

Company Registered  Intellectual Property is subsisting,  valid,  enforceable or
pending, and has not been adjudged invalid or unenforceable in whole or in part,
(iii) to Company's  knowledge,  (A) Company has the right to enforce the Company
Owned  Intellectual  Property against third parties to the extent enforcement is
available  under law, and (B) to the knowledge of the Company,  each item of the
Company  Licensed  Intellectual  Property  that  is in the  form  of  Registered
Intellectual Property is subsisting,  valid, enforceable or pending, and has not
been  adjudged  invalid  or  unenforceable  in  whole  or in  part.  Except  for
applications  listed as "abandoned" in Section 3.17(a) of the Company  Schedule,
neither Company nor any of its  Subsidiaries  has done, or failed to do, any act
or thing which may, after the

                                      -29-

Effective Time,  prejudice the validity or  enforceability  of any Company Owned
Intellectual  Property.  Except as set forth in Subsection  3.17(c)(iii)  of the
Company Schedule,  to the knowledge of Company,  no actions have been threatened
against Company or any of its Subsidiaries  seeking to restrict Company's or any
such  Subsidiary's  use of the  Company  Intellectual  Property  or  impair  the
validity or enforceability of the Company Intellectual  Property.  Except as set
forth in  Subsection  3.17(c)(iii)  of the Company  Schedule,  no Company  Owned
Intellectual  Property,  and to the  knowledge of Company,  no Company  Licensed
Intellectual  Property,  is  subject  to any  outstanding  consent,  settlement,
decree,  order,  injunction,  judgment  or  ruling  restricting  the use of such
Intellectual  Property or that would  impair the validity or  enforceability  of
such  Intellectual  Property.  Neither  Company nor any of its  Subsidiaries  is
obligated to make any payment to any person in connection with the  manufacture,
use,  sale,   importation,   distribution,   display,   modification   or  other
exploitation of any Company Owned  Intellectual  Property or any of the products

Subsidiaries,  as applicable,  is free to make, use, modify,  copy,  distribute,
sell,  license,   import,   export  and  otherwise  exploit  all  Company  Owned
Intellectual  Property on an exclusive  basis  subject to any  nonexclusive  (w)
end-user  licenses  granted to customers;  (x)  distribution  rights  granted to
resellers or distributors in the ordinary course of business;  (y) nondisclosure
or  confidentiality  agreements  pursuant  to which any person has been  granted
access to Company Owned Intellectual  Property but not the right to exploit such
Company  Owned  Intellectual  Property;  or  (z)  partner  agreements  based  on
Company's   standard  form  of  partner   agreement.   Company  or  one  of  its
Subsidiaries,  as  applicable,  is  free  to  use,  manufacture,  sell,  import,
distribute,   display   modify  or  otherwise   exploit  the  Company   Licensed
Intellectual  Property,  including  but not  limited to all  development  tools,
library functions, compilers and other third party software that are required to
operate  or modify  the  products  of  Company  or any such  Subsidiary,  in the
ordinary course of its business as presently  conducted  pursuant to and subject
only to the terms of the License-In  Agreements.  No current or former employee,
officer, director, shareholder,  consultant or independent contractor of Company
or any of its  Subsidiaries  has any valid  right,  claim or interest in or with
respect to any Company  Intellectual  Property which would impair or which could
give  rise  to the  impairment  of  the  use,  distribution,  license  or  other
exploitation  of the  Company  Intellectual  Property  by  Company  or any  such
Subsidiary.

          (d) Company Owned  Intellectual  Property set forth in Section 3.17(a)
of the Company Schedule and Company Licensed  Intellectual Property set forth in
Section  3.17(b)  of the  Company  Schedule  includes  all  of the  Intellectual
Property used in the conduct of the business of Company and its  Subsidiaries as
currently  conducted  and as  currently  expected  by Company  to be  conducted,
including,  without  limitation,  in respect of all  products  and  services  of
Company and its Subsidiaries.

          (e)  Company  and  each  of its  Subsidiaries  have  taken  reasonable
measures  and  precautions  necessary  to protect,  preserve  and  maintain  the
confidentiality  and  secrecy  of  all  trade  secrets  and  other  confidential
information used in the business of Company and such  Subsidiaries and otherwise
to maintain and protect the value of all Company  Owned  Intellectual  Property.
Neither  Company nor any of its  Subsidiaries  has  disclosed  or  delivered  or
permitted to be disclosed or delivered to any person,  and no person (other than
employees  or  consultants  of  Company  and its  Subsidiaries  which  need such
information in the course of their  employment)  has access to or has

                                      -30-

any rights with respect to,  trade  secrets and other  confidential  information
used in the business of Company or any such  Subsidiary,  the source code or any
portion or aspect of the source code used in the business of Company or any such
Subsidiary,  or any proprietary information or algorithm contained in any source
code of any software used in the business of Company or any such Subsidiary that
comprises Company Owned Intellectual  Property,  other than instances where such
trade  secrets,  confidential  information  and source  code has been  disclosed
subject  to an  agreement  with any  person  pursuant  to which  such  person is
required  to  maintain  the  confidentiality   thereof.   Without  limiting  the
generality  of the  foregoing,  except as set forth in  Section  3.17(e)  of the
Company  Schedule,  Company has, and since its initial  incorporation has had, a
policy of requiring  each employee of Company or any such  Subsidiary,  and each
independent contractor,  who is involved in, or who contributes to, the creation
or  development  of any of the  products  of Company or any such  Subsidiary  or
Intellectual Property to execute and deliver an agreement, substantially similar
to the forms of agreement  delivered by Company to Parent,  assigning to Company
full  right,  title and  interest  in and to what they  create or develop in the
scope of their employment or assignment,  as applicable.  Company complies,  and
during the time period referenced above has complied, with such policy. No event
has occurred,  and no  circumstance  or condition  exists,  that with or without
notice or lapse of time will, or would be reasonably  expected to, result in the
disclosure or delivery to any person of source code, or any portion or aspect of
source  code,  currently  maintained  in escrow.

          (f) (i) The use of the Company  Owned  Intellectual  Property  and the
operation of the business of Company and its Subsidiaries as currently conducted
and as currently anticipated to be conducted, does not infringe, misappropriate,
violate,  dilute or constitute the unauthorized use of any Intellectual Property
of any third  party and,  except as set forth in Section  3.17(f) of the Company
Schedule,  neither  Company nor any such  Subsidiary  has received any notice or
claim either oral or written asserting or suggesting that any such infringement,
misappropriation, violation, dilution or unauthorized use is or may be occurring
or has or may have  occurred.  No Action is pending or, to Company's  knowledge,
threatened,  nor is there any  pending  claim or demand,  which  challenges  the
ownership, legality, validity, enforceability, use, exploitation or modification
by  Company  or any of its  Subsidiaries  of  such  Company  Owned  Intellectual
Property.  No  Company  Owned  Intellectual  Property  and to the  knowledge  of
Company,  no  Company  Licensed   Intellectual   Property,  is  subject  to  any
outstanding order, judgment,  decree, or stipulation restricting the use thereof
by  Company  or any of its  Subsidiaries  or,  in the  case of any  Intellectual
Property  licensed to others,  restricting  the sale,  transfer,  assignment  or
licensing thereof by Company or such Subsidiary to any person.

               (ii) To  Company's  knowledge,  the use of the  Company  Licensed
Intellectual  Property does not  infringe,  misappropriate,  violate,  dilute or
constitute the unauthorized use of any Intellectual Property of any third party.

               (iii)  Company  has the right to grant the  licenses it grants in
the course of its  business.

               (iv)  Company  has the right to  conduct  its  business  as it is
currently  conducted.

          (g) No  trademark  included  in the  Company  Registered  Intellectual
Property is now involved in any  opposition or  cancellation  proceeding  and no
trademark  that is currently used by Company has been involved in any opposition
or  cancellation  proceeding.  No patent or patent  application  included in the
Company  Registered  Intellectual  Property is now involved in any interference,
reissue or reexamination proceeding.

          (h)  To  the  knowledge  of  Company,   no  person  is  infringing  or
misappropriating  any  Company  Owned  Intellectual  Property  in any respect or
making  any  unlawful  use  of  any  products  of  the  Company  or  any  of its
Subsidiaries.  Neither Company nor any of its  Subsidiaries has initiated and is
maintaining before a court or in an arbitration  proceeding Claims against other
persons for infringement by such persons of Company Owned Intellectual  Property
(including  Claims for past  infringement of Intellectual  Property).  Except as
listed in Section  3.17(h) of the Company  Schedule,  neither Company nor any of
its  Subsidiaries  has,  during the twelve (12) month  period  prior to the date
hereof,  threatened in a writing sent by Company's  legal  department or outside
counsel to initiate such proceeding.

          (i)  No  Company  Owned   Intellectual   Property  and,  to  Company's
knowledge, no Company Licensed Intellectual Property,  incorporated into or used
in conjunction with any product,  system,  program or software module that is or
was  used  in  (or  that  relates  to)  the  assets  of  Company  or  any of its
Subsidiaries,  including but not limited to the products of Company and any such
Subsidiary, contains any "back door," "time bomb," "Trojan horse," "worm," "drop
dead device," "virus" or other software routines or hardware components designed
to permit unauthorized access or to disable or erase software,  hardware or data
or otherwise  adversely  impact the operation of the Company Owned  Intellectual
Property or Company Licensed Intellectual Property or other software programs or
operating  systems  without the consent of the user.  Company has  obtained  all
approvals  necessary for exporting the products of Company and its  Subsidiaries
outside the United States and importing  Company's  products into any country in
which  Company's  products are now sold or licensed for use, and all such export
and import  approvals in the United States and  throughout  the world are valid,
current, outstanding and in full force and effect.

          (j) None of the products of Company or any of its  Subsidiaries is, in
whole or in part,  subject to the  provisions of any open source or other source
code license  agreement  that (i) requires  the  distribution  of source code in
connection with the  distribution  of the licensed  software in object code form
other than a source code escrow agreement entered into in the ordinary course of
business;  (ii) prohibits or limits Company or any such Subsidiary from charging
a fee or receiving consideration in connection with sublicensing or distributing
such licensed  software  (whether in source code or object code form);  or (iii)
allows a  customer  or  requires  that a customer  have the right to  decompile,
disassemble or otherwise  reverse  engineer the software by its terms and not by
operation of law.

          (k) The  consummation  of the  Arrangement  will not  result in Parent
being bound by any  non-compete or other  restrictions  on the operations of any
business  of Parent or the  granting  by Parent of any rights or licenses to any
Company Intellectual Property to a third party (including, without limitation, a
covenant not to sue).

properties  and to carry on its  business as it is now being  conducted,  except

and its  Subsidiaries is in possession of all Approvals  necessary to own, lease
and operate the properties it purports to own,  operate or lease and to carry on
its business as it is now being conducted, except where the failure to have such

have a Material Adverse Effect on Parent. Each of Parent and its Subsidiaries is
duly qualified or licensed as a foreign  corporation  to do business,  and is in
good standing, in each jurisdiction where the character of the properties owned,
leased  or  operated  by  it  or  the  nature  of  its  activities   makes  such
qualification  or licensing  necessary,  except for such  failures to be so duly
qualified or licensed and in good standing that would not,  either  individually
or in the aggregate, be reasonably expected to have a Material Adverse Effect on
Parent.

other  documents,   including  any  financial  statements  or  other  documents,
including  any  schedules  included  therein,  are  referred  to as the  "Parent
Documents").  Parent Documents,  at the time filed (and if amended or superseded

filing), (i) did not contain any misrepresentation (as defined in the 1933 Act),

quarterly unaudited consolidated  financial statements of Parent,  including the
notes thereto,  included in Parent Documents (the "Parent Financial Statements")
complied  as to  form  in  all  material  respects  with  applicable  accounting
requirements  in the U.S.  and with  the  published  rules  and  regulations  of
applicable  Governmental Entities, the SEC and Nasdaq with respect thereto as of
their  respective  dates, and have been prepared in accordance with US GAAP. The
Parent  Financial  Statements  present  fairly,  in all material  respects,  the
consolidated financial position,  results of operations and cash flows of Parent
and its  subsidiaries  at the dates and during  the  periods  indicated  therein
(subject,  in the case of unaudited  statements,  to normal,  recurring year-end
adjustments  and the  absence of notes  thereto)  and  reflect  appropriate  and
adequate  reserves in respect of contingent  liabilities,  if any, of Parent and
its subsidiaries on a consolidated  basis.  There has been no change in Parent's
accounting  policies,  except as  described  in the  notes to  Parent  Financial

detail the material  transactions  and  dispositions of the assets of Parent and
its  subsidiaries  and (iii)  accurately  and fairly  reflect  the basis for the
Parent  Financial  Statements.  Parent has  devised  and  maintains  a system of
internal accounting  controls  sufficient to provide reasonable  assurances that
(i)  transactions  are  executed  in  accordance  with  management's  general or
specific  authorization;  and (ii) transactions are recorded as necessary (A) to
permit  preparation of consolidated  financial  statements in conformity with US
GAAP  and  (B) to  maintain  accountability  of the  assets  of  Parent  and its
subsidiaries.

          (d) Each Parent Document containing financial statements that has been
filed with or submitted to the SEC since July 31, 2002,  was  accompanied by the
certifications  required to be filed or  submitted by Parent's  chief  executive
officer and chief financial officer pursuant to the  Sarbanes-Oxley  Act; at the
time of filing or submission of each such certification,  such certification was
true and  accurate and complied  with the  Sarbanes-Oxley  Act and the rules and
regulations   promulgated    thereunder;    such   certifications   contain   no
qualifications  or exceptions to the matters certified therein and have not been
modified  or  withdrawn;  and  neither  the Parent nor any of its  officers  has
received  notice from any  Governmental  Entity  questioning or challenging  the
accuracy,  completeness,  form  or  manner  of  filing  or  submission  of  such
certifications.

          (e) To the  knowledge  of Parent,  no employee of Parent or any of its

discriminated  against an employee of Parent or such Subsidiary in the terms and

money as a condition  to or a necessity  for the right or ability of Parent or a
Subsidiary,  as the case may be, to conduct its business in a manner in which it
currently  carries on such  business  that would be  reasonably  expected to (i)
have,  individually or in the aggregate,  a Material Adverse Effect on Parent or

neither Parent nor any Subsidiary is subject to any pending or, to the knowledge
of Parent,  threatened  warranty,  negligence,  performance  or other  Claims or

on  a  no-names   basis,   Governmental   Entities  having   jurisdiction   over
environmental  matters in order to discuss issues known to such  regulators that
relate to the  properties.  In addition,  Company  shall  permit  Parent and its
accountants,  counsel and other representatives to meet with the Chief Financial
Officer and other employees or  representatives  of Company and its Subsidiaries
responsible for the Financial  Statements,  the internal controls of Company and
each  Subsidiary and the disclosure  controls and procedures of Company and each
Subsidiary  to discuss such matters as Parent may deem  reasonably  necessary or
appropriate for Parent to satisfy its obligations  under Sections 302 and 906 of
the  Sarbanes-Oxley  Act and any  rules and  regulations  relating  thereto.  No
information  or knowledge  obtained by Parent in any  investigation  pursuant to
this  Section  6.1 will  affect or be deemed to  modify  any  representation  or
warranty contained herein or the conditions to the obligations of the parties to
consummate the Arrangement.  Parent will hold any information  obtained pursuant
to this Section 6.1(b) in confidence in accordance  with, and otherwise  subject
to, the provisions of the Confidentiality Agreement.

          (c) Change in Tax Law.  If a change in tax law is enacted  and becomes
effective on a date which is on or prior to the Effective Time pursuant to which
beneficial  owners of Company  Common Shares who are Canadian  residents and who
hold  their  shares  as  capital  property  for  purposes  of the ITA  (and  any
applicable equivalent provincial  legislation) may exchange their Company Common
Shares for Parent Common Shares on a tax-deferred  basis for purposes of the ITA
and any  applicable  equivalent  provincial  legislation  and such  federal  and
provincial  legislation  does not require such  shareholders  to enter into gain
recognition  agreements  or contain other  provisions  which are adverse to such
shareholders,  then,  at the option of Parent,  no  Exchangeable  Shares will be
issued and the Plan of Arrangement will be amended accordingly.

     6.2 No Solicitation.
         ---------------

          (a) From the date hereof until the Effective Time or, if earlier,  the
termination of this Agreement,  Company shall  immediately cease and cause to be
terminated  any  existing  discussions  with  any  Person  that  relate  to  any
Acquisition  Proposal,  and Company  shall not, nor shall it permit or authorize
its Subsidiaries,  or any of their respective officers,  directors or employees,
or any investment banker,  attorney or other advisor or representative  retained
by any of them to, directly or indirectly: (i) solicit,  initiate,  encourage or
otherwise  knowingly  facilitate  any  Acquisition  Proposal or any inquiries or
proposals relating thereto;  or (ii) engage in discussions or negotiations with,
or disclose any non-public  information  relating to Company or its Subsidiaries
or  afford  access  to the  properties,  books  or  records  of  Company  or its
Subsidiaries to, any Person (other than Parent or any

                                      -47-

<PAGE>

designees of Parent)  concerning or in connection with an Acquisition  Proposal;
provided,  however,  that in each case, if (A) after the date of this  Agreement
and prior to the date of any  securityholder  approval  of the  Arrangement,  an
unsolicited,  bona fide written  Acquisition  Proposal is made to Company and is
not  withdrawn;  (B) Company's  Board of Directors  reasonably  believes in good
faith,   after  consultation  with  Company's   financial  advisor,   that  such
Acquisition  Proposal  constitutes  (if  consummated  as  proposed)  a  Superior
Proposal;  (C) Company's Board of Directors  reasonably  believes in good faith,
after  consultation  with Company's  outside legal counsel,  that the failure to
engage in such negotiations or discussions, to provide such information would be
inconsistent  with the duties of the Board of  Directors  of Company  set out in
section 122 of the CBCA; (D) prior to furnishing any such nonpublic  information
to, entering into discussions or negotiations with, any Person, Company receives
from such Person an executed  confidentiality  agreement (including "standstill"
provisions) no less favorable to Company than the Confidentiality Agreement; and
(E) at the time of or prior to furnishing any such nonpublic information to such
Person,  Company  furnishes such nonpublic  information to Parent (to the extent
such  nonpublic  information  has not been  previously  furnished  by Company to
Parent),  then Company may (1) furnish  information  with respect to Company and
its   Subsidiaries  to  such  Person,   (2)  participate  with  such  Person  in
negotiations  regarding such Acquisition Proposal, or (3) enter into discussions
or negotiations  with, such Person.

          (b) Neither  Company's  Board of Directors nor any  committee  thereof
shall (i)  withhold,  withdraw  or modify,  or  propose  publicly  to  withhold,
withdraw or modify, in a manner adverse to Parent, the approval,  recommendation
or  declaration  of  advisability  by  Company's  Board of Directors or any such
committee  of the  Arrangement  or this  Agreement,  (ii)  recommend,  adopt  or
approve,  or propose  publicly to recommend,  adopt or approve,  any Acquisition
Proposal or Superior Proposal or (iii) approve or recommend, or propose publicly
to approve or recommend,  or allow Company or any of its Subsidiaries to execute
or enter into, any letter of intent,  memorandum of understanding,  agreement in
principle,  merger  agreement,  acquisition  agreement,  combination  agreement,
option  agreement,  joint  venture  agreement,  partnership  agreement  or other
similar agreement (each an "Acquisition  Agreement")  constituting or related to
any  Acquisition  Proposal or Superior  Proposal  (any action  described  in the
foregoing clauses (i), (ii) or (iii) of this Section 6.2(b) being referred to as
a "Company Adverse Recommendation  Change").  Notwithstanding the foregoing,  at
any time prior to the approval of the  Arrangement at the Company  Meeting by at
least 66 2/3% of the  holders  of  Company  Common  Shares,  Company's  Board of
Directors may make a Company Adverse  Recommendation Change, if, prior to taking
such action,  Company's Board of Directors  received advice of Company's outside
legal  counsel that such action is required in order to  discharge  properly the
fiduciary  duties of Company's Board of Directors;  provided,  however,  that no
Company  Adverse  Recommendation  Change may be made in  response  to a Superior
Proposal,  until after 72 hours following  Parent's receipt of written notice (a
"Notice of Adverse  Recommendation") from Company advising Parent that Company's
Board of Directors intends to make such a Company Adverse  Recommendation Change
and  specifying  the terms and  conditions of such  Superior  Proposal (it being
understood  and agreed that any  amendment to the  financial  terms or any other
material  term of such Superior  Proposal  shall require a new Notice of Adverse
Recommendation  and a new 72 hour  period).  Following  receipt  of a Notice  of
Adverse  Recommendation,  Parent  shall  have  the  opportunity  to  present  to
Company's Board of Directors

                                      -48-

<PAGE>

revised terms for the  consummation of the  Arrangement,  including any proposed
amendments or  modifications to this Agreement in respect of such revised terms.
The Company  Board of  Directors  shall  consider in good faith any such revised
terms and amendments and modifications submitted to it by Parent. In determining
whether  to make a  Company  Adverse  Recommendation  Change  in  response  to a
Superior Proposal, Company's Board of Directors shall take into account Parent's
revised terms and any proposed  changes to the terms of this Agreement  proposed
by Parent in response to a Notice of Adverse Recommendation or otherwise. Before
making any Company Adverse Recommendation  Change,  Company's Board of Directors
shall  consider  whether  the  revised  terms  offered by Parent are  reasonably
equivalent  or  superior  from the  financial  point of view of Company  and its
shareholders  to the  terms of the  Superior  Proposal  and,  if such  terms are
determined  by a vote of a  majority  of  Company's  Board  of  Directors  to be
reasonably  equivalent or superior  from the financial  point of view of Company
and its shareholders to the terms of the Superior  Proposal,  Company's Board of
Directors  shall  accept  at a  meeting  duly  called  and  held,  duly  adopted
resolutions (x) approving and declaring  advisable the terms of any such revised
proposal  by  Parent  and  any  definitive   agreement  proposed  in  connection
therewith,  (y)  directing  that the  adoption of the terms of any such  revised
proposal by Parent and any definitive agreement proposed in connection therewith
be  submitted  to a vote at a meeting of the  shareholders  of  Company  and (z)
recommending that the shareholders of Company approve and adopt the terms of any
such  revised  proposal  by Parent  and any  definitive  agreement  proposed  in
connection  therewith.  If  Company  has  elected  to  make  a  Company  Adverse
Recommendation  Change  following  receipt of a Superior  Proposal and complying
with the procedures set forth in this Section 6.2(b) and after  determining by a
vote of the full Company Board of Directors  that any revised terms and proposed
changes of Parent are not  reasonably  equivalent or superior from the financial
point of view of Company and its shareholders to terms of the Superior Proposal,
Company  shall  terminate  this  agreement by delivering to Parent (i) a written
notice of termination of this Agreement pursuant to this Section 6.2(b),  (ii) a
wire transfer of immediately  available  funds in the amount of the  Termination
Fee and (iii) a written  acknowledgement  that  Company and  Company's  Board of
Directors have complied with all of their covenants and obligations  pursuant to
this Section  6.2(b) and that Company is obligated to pay the  Termination  Fee.

          (c) In addition to the  obligations of Company set forth in paragraphs
(a) and (b) of this Section 6.2, Company shall promptly, and in any event within
twenty-four  (24) hours,  advise  Parent  orally and in writing of any bona fide
Acquisition Proposal or Superior Proposal or any inquiry with respect to or that
could  reasonably  be expected to lead to any  Acquisition  Proposal or Superior
Proposal and the material terms and conditions of any such Acquisition  Proposal
or Superior Proposal (including any changes thereto).  Company shall keep Parent
informed of any material change to the terms of any such Acquisition Proposal or
Superior Proposal.

          (d)  Company  shall not  release or permit  the  release of any Person
from, or waive or permit the waiver of any  provision  of, any  confidentiality,
"standstill" or similar  agreement (other than as required pursuant to the terms
thereof  as in effect on the date  hereof)  under  which  Company  or any of its
Subsidiaries  has any rights,  or fail to use reasonable best efforts to enforce
or cause to be enforced  each such  agreement at the request of Parent.  Company
shall use its reasonable best efforts to ensure that its Subsidiaries and any of
their  respective  officers,  directors or employees or

                                      -49-

<PAGE>

any investment banker,  attorney or other advisor or representative  retained by
any of them are  aware of the  provisions  of this  Section  6.2,  and  shall be
responsible  for any breach of this Section 6.2 by it and its  Subsidiaries  and
any of their  respective  officers,  directors or  employees  or any  investment
banker, attorney or other advisor or representative retained by any of them.

          (e) Nothing  contained in this  Agreement  shall  prohibit  Company or
Company's   Board  of  Directors   from  taking  and   disclosing  to  Company's
shareholders  a position with respect to a tender or exchange offer or take-over
bid by a third party pursuant to Rules 14d-9 and 14e-2(a)  promulgated under the
1934  Act  or  Section  99  under  the  Securities  Act  (Ontario).

     6.3 Public Disclosure. Parent and Company will consult with each other, and
to the extent practicable,  agree, before issuing any press release or otherwise
making any public statement with respect to the  Arrangement,  this Agreement or
an  Acquisition  Proposal and will not issue any such press  release or make any
such public statement prior to such  consultation,  except as may be required by
law or any listing agreement with a national  securities  exchange.  The parties
have agreed to the text of the joint  press  release  announcing  the signing of
this Agreement.

     6.4 Reasonable Best Efforts; Notification.
         -------------------------------------

          (a) Upon the terms and  subject  to the  conditions  set forth in this
Agreement,  each of the parties  agrees to use its  reasonable  best  efforts to

Agreement,  all in  accordance  with the terms of  Section  5.1(e) of the Rights
Agreement;

               (ii) advise Parent as reasonably  requested,  as to the aggregate
tally of the  proxies and votes  received in respect of the Company  Meeting and

purportedly  exercising  the Dissent  Rights;  and not settle or compromise  any
claim  brought  by  any  present,  former  or  purported  holder  of  any of its
securities in connection with the Arrangement; and

writing:

                    (A) of any event  occurring  subsequent  to the date of this

in this  Agreement  (except any such  representation  or warranty  which  speaks
solely as of a date prior to the occurrence of such event),  if made on or as of
the date of such  event or the  Effective  Time,  untrue  or  inaccurate  in any
material respect;

                    (B) of any event or  circumstance  which would be reasonably

                                      -51-

          (c) Parent Parties shall perform all obligations required or desirable
to be  performed  by them under this  Agreement,  to  cooperate  with Company in
connection  therewith,  and to do all  such  other  acts  and  things  as may be
necessary or desirable in order to  consummate  and make  effective,  as soon as

the date of such  event or the  Effective  Time,  untrue  or  inaccurate  in any
material respect;

                    (B) of any event or  circumstance  which would be reasonably

<PAGE>

Company Common Shares by holders of the Company Common Shares resident in Canada

holders  who  are  otherwise  eligible  for  such  treatment.

          (f) As soon as practicable  following the execution of this Agreement,
Company shall  facilitate and cooperate with Parent and its  representatives  in

Partnership,  successor to California Public Employee's Retirement System, to be
paid in full in  accordance  with the terms of such  lease on or before  May 31,
2004.

          (h) Company  agrees to provide,  and will cause its  Subsidiaries  and
will use its reasonable best efforts to cause its and their respective officers,
employees, advisers and representatives to provide, all necessary cooperation in
connection  with  taking  the  actions  set  forth on  Schedule  6.4(h)  to this

extent permitted under applicable Laws and the  Sarbanes-Oxley  Act, Parent will
cause  Company  to  fulfill  its  obligations  pursuant  to any  indemnification
agreements  between Company and its directors and officers in effect immediately
prior to the Effective Time (the "Indemnified  Parties") and any indemnification
provisions under Company Charter Documents as in effect on the date hereof.  The
Articles of  Incorporation  and Bylaws of Company will contain  provisions  with
respect to exculpation and indemnification that are at least as favorable to the
Indemnified Parties as those contained in Company Charter Documents as in effect
on the date hereof, which provisions will not be amended,  repealed or otherwise
modified  for a period of six (6) years  from the  Effective  Time in any manner
that would adversely  affect the rights  thereunder of individuals who, prior to
the  Effective  Time,  were  directors  or  officers  of  Company,  unless  such
modification  is required by law. For a period of six years after the  Effective
Time, Parent will cause Company to maintain in effect, if available,  directors'
and  officers'  liability  insurance  covering  those  persons who are currently
covered by Company's  directors' and officers'  liability  insurance policy with
respect to Claims  arising  from facts or events that  occurred on or before the
Effective Time on terms equivalent to those applicable to the current  directors
and  officers of  Company;  provided,  however,  that in no event will Parent or
Company be required to expend in excess of $1,438,250 to acquire a six-year tail
insurance policy at the time of Closing to satisfy this requirement.

     6.6 Company  Affiliate  Agreement.  Set forth in Section 6.6 of the Company
Schedule  is a list of those  persons  who may be  deemed  to be,  in  Company's
reasonable  judgment,  affiliates  of  Company  within  the  meaning of Rule 145
promulgated  under the 1933 Act (each,  a  "Company  Affiliate").  Company  will
provide Parent with such information and documents as Parent reasonably requests
for purposes of  reviewing  such list.  Company  shall use its  reasonable  best
efforts to cause

                                      -53-

<PAGE>

each Company Affiliate to enter into an Affiliate Agreement in substantially the
form attached hereto as Exhibit F as promptly as practicable  following the date
hereof.

     6.7  Regulatory  Filings;  Reasonable  Best  Efforts.  As  soon  as  may be
reasonably  practicable following the date hereof, Company and Parent each shall
file merger  notification  forms required by the merger  notification or control
laws and  regulations of any  applicable  jurisdiction  which Parent  reasonably
determines to be necessary or advisable.  Company and Parent each shall promptly
(a) supply  the other with any  information  which may be  required  in order to
effectuate  such  filings  and  (b)  supply  any  additional  information  which
reasonably may be required by the  competition or merger control  authorities of
any applicable  jurisdiction.  Each of Parent and Company shall promptly  inform
the other party of any  material  communication  received by such party from any
Person in  connection  with such  filings,  and  shall use its  reasonable  best
efforts to give the other party the  opportunity  to participate in any meetings
or  conferences  with such  Governmental  Entity.

     6.8 Company Stock  Transfer  Agreement.  Company  hereby  acknowledges  the
restrictions  on  transfer  of the Shares (as  defined in the Voting  Agreement)
contained in Section 3.1 of the Voting Agreement. Company agrees not to register
the transfer  (book-entry or otherwise) or any  certificated  or  uncertificated
interest  representing  any  Shares.  Company  further  agrees to  instruct  its
transfer  agent not to transfer  any  certificated  or  uncertificated  interest
representing  any Shares,  until (i) the transfer  agent has  received  Parent's
consent to such a transfer,  or (ii) the Voting  Agreement  has been  terminated
pursuant to Section 4.1 thereof.

     6.9 Employee  Stock Purchase Plan.  Company shall  immediately  suspend and
shall not accept any further payroll contributions under its 2002 Employee Stock
Purchase Plan ("ESPP") after the date of this  Agreement.  Company will take all
necessary  actions  to  cause  the  termination  of  the  ESPP  and  all  rights
thereunder,  in each  case,  no later  than the  Effective  Time.

     6.10 Company Options.
          ---------------

          (a) The Arrangement  shall provide that each Company Stock Option that
becomes  exercisable  as  a  result  of  the  Arrangement,  notwithstanding  any
contingent  vesting  provisions to which it might  otherwise  have been subject,
shall be deemed to be  conditionally  vested and exercisable only as part of the
Arrangement unless otherwise agreed to by the option holder and Parent.

          (b)  Each  holder  of  a  Company  Stock  Option  (including,  without
limitation,  Company Stock Options referred to in subparagraph (a)) may elect to
conditionally  exercise  one or  more  Company  Stock  Options  as  part  of the
Arrangement  by  delivering  to  the  Depositary  (as  defined  in the  Plan  of
Arrangement)  on or prior to the  Election  Deadline  (as defined in the Plan of
Arrangement)  (i) a notice of the conditional  exercise of such holder's Company
Stock  Options  indicating  whether  the holder  elects a "Cash  Exercise"  or a
"Cashless  Exercise"  and (ii) a validly  completed  Letter of  Transmittal  and
Election  Form,  electing  whether such holder wishes to receive  Parent Shares,
Exchangeable  Shares  or Per  Share  Cash  Consideration  pursuant  to  Sections
2.2(1)(c),

                                      -54-

<PAGE>

(d) or (e),  respectively,  under the Plan of  Arrangement  in exchange  for the
Company  Common  Shares  issued to or  received  by the holder  pursuant  to the
exercise of such holder's Company Stock Options.

          (c) Each "Cash  Exercise" shall be accompanied by a certified check or
bank draft in an amount equal to the product  obtained by multiplying the number
of Common Shares in respect of which the Company  Stock Option is  conditionally
exercised (the "Number of Options  Exercised") by the exercise price per Company
Stock Option (the "Exercise Price"). In the event of a "Cashless Exercise",  the
holder shall transfer the Company Stock Option to the Company  immediately prior
to the Effective  Time in exchange for Company Common Shares using the following
formula:

         X = Y(A-B)
             ------
                A

   Where: X  = The number of shares of Company Common Shares to be issued to the
               Company Stock Option holder.

          Y  = The number of Company  Common  Shares under the holder's  Company

to Parent, including but not limited to a divestiture or hold separate order; or

Company as currently  conducted,  or to own, use or exploit Company's assets, in
each case taking into account the  activities  reflected in the  Arrangement  or

<PAGE>

          (a) by  mutual  written  consent  duly  authorized  by the  Boards  of
Directors of Parent and Company;

          (b) by either  Company or Parent,  if the  Arrangement  shall not have
been  consummated  by August 31, 2004 for any reason (the  "Termination  Date");
provided,  however,  that if on the  Termination  Date  the  only  condition  to
effecting the Arrangement  remaining to be satisfied is the effectiveness of the
Form S-3 as contemplated by Section 7.1(e)(iv),  then the Termination Date shall
automatically be extended to October 31, 2004; provided further,  however,  that
the right to terminate  this  Agreement  under this Section  8.1(b) shall not be
available to any party whose action or failure to act has been a principal cause
of or resulted in the failure of the Arrangement to occur on or before such date
and such action or failure to act constitutes a breach of this Agreement;

          (c) by either Company or Parent, if there shall be passed any Law that
makes the consummation of the Arrangement illegal or otherwise prohibited, or if
a Governmental  Entity shall have issued an order, decree or ruling or taken any
other  action,  in any  case  having  the  effect  of  permanently  restraining,
enjoining or otherwise prohibiting the Arrangement,  which order, decree, ruling
or other action is final and nonappealable;

          (d) by either  Company or Parent,  if the  required  approvals  of the
shareholders and  optionholders of Company  contemplated by this Agreement shall
not have been obtained by reason of the failure to obtain the required vote at a
meeting of Company  securityholders duly convened therefor or at any adjournment
thereof;  provided,  however,  that the right to terminate this Agreement  under
this  Section  8.1(d)  shall not be  available  to Company  where the failure to
obtain the approval of the  securityholders of Company shall have been caused by
the  action or  failure  to act of  Company  and such  action or  failure to act
constitutes a breach by Company of this Agreement;

          (e)  by  Company,  upon a  breach  of  any  representation,  warranty,
covenant or agreement on the part of Parent set forth in this  Agreement,  or if
any  representation  or warranty of Parent shall have become  untrue,  in either
case such that the  conditions  set forth in Section  7.2(a) or  Section  7.2(b)
would  not be  satisfied  as of the time of such  breach  or as of the time such
representation  or warranty  shall have  become  untrue,  provided  that if such
inaccuracy  in Parent's  representations  and  warranties or breach by Parent is
curable by Parent through the exercise of its commercially  reasonable  efforts,
then Company may not  terminate  this  Agreement  under this Section  8.1(e) for
thirty (30) days after delivery of written notice from Company to Parent of such
breach, provided Parent continues to exercise commercially reasonable efforts to
cure such  breach (it being  understood  that  Company  may not  terminate  this
Agreement  pursuant  to this  paragraph  (e) if such  breach  by Parent is cured
during such thirty-day period);

          (f) by Parent, upon a breach of any representation, warranty, covenant
or  agreement  on the part of  Company  set forth in this  Agreement,  or if any
representation  or warranty of Company shall have become untrue,  in either case
such that the conditions set forth in Section 7.3(a) or Section 7.3(b) would not
be satisfied as of the time of such breach or as of the time such representation
or warranty  shall have  become  untrue,  provided  that if such  inaccuracy  in
Company's  representations  and  warranties  or breach by  Company is curable by
Company through the exercise of

                                      -60-

<PAGE>

its  commercially  reasonable  efforts,  then  Parent  may  not  terminate  this
Agreement  under this  Section  8.1(f) for thirty  (30) days after  delivery  of
written notice from Parent to Company of such breach, provided Company continues
to  exercise  commercially  reasonable  efforts  to cure such  breach  (it being
understood  that  Parent  may not  terminate  this  Agreement  pursuant  to this
paragraph (f) if such breach by Company is cured during such thirty-day period);

          (g) by Parent, if a Triggering Event shall have occurred; or

          (h) by Company in accordance with Section 6.2(b);  provided,  however,
in order for the  termination of this Agreement  pursuant to this Section 8.1(h)
to be deemed  effective,  Company  shall have  complied in all respects with all
provisions contained in Sections 6.2(a), 6.2(b) and 6.2(c), including the notice
provisions  therein,  and with applicable  requirements of Sections 8.2 and 8.3,
including the payment of the Termination Fee.

Agreement  under  Section  8.1  above  will be  effective  immediately  upon the
delivery of written notice of the terminating  party to the other parties hereto
(except with respect to a termination pursuant to Sections 8.1(e) and (f), which
shall be effective upon  satisfaction  of the terms contained  therein).  In the
event of the  termination  of this  Agreement as provided in Section  8.1,  this
Agreement  shall be of no further  force or  effect,  except (i) as set forth in
Section 6.1(a),  Section 8.2,  Section 8.3 and Article IX (General  Provisions),
each of which shall survive the  termination  of this Agreement and (ii) nothing
herein shall  relieve any party from  liability  for any willful or  intentional
breach of this  Agreement.  No termination  of this  Agreement  shall affect the
obligations of the parties contained in the  Confidentiality  Agreement,  all of
which obligations shall survive termination of this Agreement in accordance with
their terms.

         -----------------

          (a)  General.  Except as set forth in this  Section  8.3, all fees and

this Agreement,  a Company  Acquisition is consummated or Company enters into an
agreement or letter of intent  providing  for a Company  Acquisition,  in either
case,  which  constitutes a Superior  Proposal (as compared to the  transactions
contemplated  by  this  Agreement  on  the  date  of  the  termination  of  this
Agreement), with any party, then

Company shall pay Parent in immediately  available  funds an amount equal to the
$3,100,000  upon the earlier to occur of (x) the  consummation of such a Company

               (iv) Company  acknowledges that the agreements  contained in this
Section  8.3(b) are an integral part of the  transactions  contemplated  by this
Agreement, and that, without these agreements,  Parent would not enter into this

due pursuant to this Section 8.3(b) and, in order to obtain such payment, Parent
makes a claim that  results in a judgment  against  Company  for the amounts set
forth in this Section 8.3(b),  Company shall pay to Parent its reasonable  costs
and expenses (including  reasonable  attorneys' fees and expenses) in connection
with such suit,  together with interest on the amounts set forth in this Section
8.3(b) at the prime rate of  Citibank,  N.A. in effect on the date such  payment
was required to be made.  Payment of the fees  described in this Section  8.3(b)

breach of this  Agreement.  In no event  will more  than one fee be  payable  in
connection with the termination of the Agreement.

     8.4  Amendment.  Subject to  applicable  law and the  Interim  Order,  this

each of Parent  and  Company.  Company  agrees to make such  amendments  to this
Agreement,  the Plan of Arrangement and the other agreements  referred to herein
as may be  reasonably  required  to  ensure  that the  proposed  effect  of such
agreements are maintained following any assignment of the rights,  interests and
obligations of Exchangeco in accordance with Section 9.10 of this Agreement.

party contained  herein or in any document  delivered  pursuant hereto and (iii)

forth in an  instrument  in  writing  signed on behalf of such  party.  Delay in
exercising any right under this Agreement  shall not constitute a waiver of such
right.

     A. Parent,  Orion  Exchangeco,  Ltd., a corporation  organized and existing
under the Business  Corporations Act (British Columbia) and Company are entering
into a Combination  Agreement  dated as of the date hereof (as amended from time
to time, the "Combination Agreement"), pursuant to which Parent will acquire all

terms used but not defined in this Agreement shall have the meanings ascribed to
them in the Combination Agreement;

     B. As of the date hereof,  each Shareholder is the record and/or beneficial
owner of the  number of Shares  (as  defined  below)  set  forth  opposite  each
Shareholder's name in Exhibit A hereto (the "Existing Shares" and, together with
any Company Common Shares acquired of record and/or beneficially by Shareholders
after  the  date  hereof,  whether  upon  the  exercise  of  warrants,  options,
conversion  of  convertible  securities,  or by  means  of  purchase,  dividend,
distribution, split-up, recapitalization, combination, exchange of shares, gift,
bequest,  inheritance or as a successor in interest in any capacity or otherwise
and any  shares  into which or for which any or all of the  Existing  Shares and
additional shares may be changed or exchanged, the "Shares"); and

     C. As a condition and inducement to Parent's  willingness to enter into the
Combination  Agreement and incurring the obligations  set forth therein,  Parent
has required that the Shareholders agree to enter into this Agreement.

     NOW,   THEREFORE,   in  consideration   of  the  covenants,   promises  and
representations set forth herein, and for other good and valuable consideration,
the receipt and sufficient of which are hereby  acknowledged,  the parties agree
as follows:

                                    ARTICLE I

                                VOTING AGREEMENT

     1.1 Voting  Agreement.  (a) Each  Shareholder  hereby agrees that, from and
after the date hereof and until the earlier to occur of the  Effective  Time and
the termination of this Agreement in accordance with its terms, at every meeting
of the  shareholders  of  Company,  however  called,  and at  every  adjournment
thereof,  and in every action by written consent of the shareholders of Company,
such Shareholder shall, provided that such Shareholder has not

<PAGE>

received  notice from Parent (which notice may be delivered at any such meeting)
stating  Parent's  intention  to exercise  the Proxy at such meeting (as defined
below),  appear at any such meeting or otherwise  cause the Shares to be counted
as present  thereat for  purposes of  establishing  a quorum,  and shall vote or
consent (or cause to be voted or consented) such  Shareholder's  Shares:  (i) in
favor of the approval and adoption of the Combination Agreement, the Arrangement
and all the transactions contemplated by the Combination Agreement and otherwise
in such manner as may be necessary to consummate the Arrangement; (ii) except as
otherwise  agreed to in  writing  in advance  by  Parent,  against  any  action,
proposal,  agreement  or  transaction  that is intended or could  reasonably  be
expected  to  result  in  a  breach  of  any  covenant,  obligation,  agreement,
representation or warranty of Company contained in the Combination  Agreement or
of such Shareholder  contained in this Agreement;  and (iii) against any action,
proposal,  agreement  or  transaction,   including,  but  not  limited  to,  any
Acquisition Proposal (other than the Arrangement,  the Combination  Agreement or
the transactions  contemplated  thereby),  that could be reasonably  expected to
result in any of the conditions to Company's  obligations  under the Combination
Agreement  (whether or not  theretofore  terminated) not being fulfilled or that
could  reasonably  be expected  to impede,  interfere  with or  prevent,  delay,
postpone,   discourage  or  adversely  affect  the  Combination  Agreement,  the
Arrangement or this Agreement.

     (b) If a Shareholder fails for any reason to vote his, her or its Shares as
required by Section  1.1(a),  the holder of the Proxy (as defined  below)  shall

accordance with Section 1.1(a) and the Proxy.

     (c) Each Shareholder  hereby agrees that such  Shareholder  shall not enter

authorization,  execution and delivery of this  Agreement by Parent,  constitute
legal, valid and binding  obligations of such Shareholder,  enforceable  against

equitable remedies such as specific  performance and injunctive relief is within
the discretion of a court of competent jurisdiction.

entity),  (ii) assuming  satisfaction of the  requirements  set forth in Section
2.3(b)  below,  conflict  with or violate the terms of any trust  agreements  or
equivalent  organizational documents of such Shareholder (if such Shareholder is

or by which the Shares owned by such  Shareholder  are bound or affected or (iv)
result in any breach of, or  constitute  a default (or an event that with notice
or lapse of time or both would  become a default)  under,  or give to others any
rights of termination,  amendment, acceleration or cancellation of, or result in
the  creation  of a lien  or  encumbrance  on any of the  Shares  owned  by such
Shareholder  pursuant  to,  any  note,  bond,  mortgage,  indenture,   contract,

to which such  Shareholder is a party or by which such Shareholder or the Shares
owned by such Shareholder are bound or affected,  except for any such conflicts,
violations, breaches, defaults or other occurrences that would not, individually
or  in  the  aggregate,   prevent  or  materially  delay   consummation  of  the
transactions  contemplated by this Agreement and the Proxy or otherwise  prevent
or materially delay such Shareholder from performing its obligations  under this
Agreement and the Proxy.

Securities  Laws,  the U.S state  securities  laws,  state takeover laws and any
requirements  of foreign  Governmental  Entities  and (ii) where the  failure to
obtain such  consents,  approvals,  authorizations  or permits,  or to make such
filings or notifications, would

                                      -3-
<PAGE>

not, individually or in the aggregate,  prevent or materially delay consummation
of the  transactions  contemplated  by this Agreement and the Proxy or otherwise
prevent such  Shareholder  from performing its material  obligations  under this
Agreement and the Proxy.

     2.4 Title to the Shares.  As of the date hereof,  such  Shareholder  is the
record and/or  beneficial  owner of the number of Shares set forth opposite such
Shareholder's  name in  Exhibit A hereto  with full  power to vote or direct the
voting of such  Shares  owned of record  as  indicated  in  Exhibit  A,  without
restriction,  for and on behalf of all beneficial owners of such Shares.  Except
as set forth on Exhibit A, such Shares are all the Company  Common  Shares owned
of record  and/or  beneficially  by such  Shareholder.  The Shares owned by such
Shareholder are now and, at all times during the term hereof will be, owned free

Proposal is made,  specifying the material terms and conditions  thereof and the
identity of the party making such proposal or offer or inquiry or contact.  Each

                                CONSENT OF SPOUSE

     The undersigned is the spouse of [________________], a Shareholder (as such
term  is  defined  therein)  in the  foregoing  Voting  Agreement  (the  "Voting
Agreement")  dated  as  of  April  12,  2004,  among  At  Road,  Inc.,  and  the
shareholders of MDSI Mobile Data Solutions Inc. (the  "Company")  party thereto.
Capitalized  terms used herein but not otherwise  defined  herein shall have the
meanings ascribed thereto in the Voting Agreement.

     I hereby  acknowledge  that I have carefully  reviewed the Voting Agreement
and such other  documents as I have deemed  appropriate.  I have  discussed  the
contents of the Voting Agreement, to the extent I felt necessary,  with my legal
counsel. I understand fully the transactions  described in the Voting Agreement,
and I hereby approve of and consent to all such transactions. I am aware that by
the provisions of the Voting Agreement, my spouse agrees, among other things, to
vote all of the  outstanding  shares of common stock of Company that he now owns
or hereafter  acquires (the  "Company  Common  Shares"),  including my community
property interest therein, if any, in accordance with the Voting Agreement,  and
that my spouse agrees,  among other things,  to certain  matters  related to the
control and  disposition of Company Common Shares.  I hereby agree, on behalf of
myself  and all  persons  who may  claim  on my  behalf,  that  upon  any  legal
separation from or dissolution of my marriage to my present spouse,  or upon the
death of my spouse,  neither I nor  anyone  claiming  on my behalf  will seek to
partition my or my spouse's community property interest in Company Common Shares
and that in any such event I shall be entitled  only to the value of my interest
in such Company Common  Shares,  if any, and that I shall have no claim or right
to Company Common Shares themselves.

                                  EXECUTED this 12th day of April, 2004.

                                      PROXY

     The  undersigned   shareholder  of  MDSI  Mobile  Data  Solutions  Inc.,  a
corporation organized and existing under the laws of Canada ("Company"),  hereby
irrevocably  (to the fullest extent  permitted by law) appoints the directors on
the Board of Directors of At Road, Inc., a Delaware corporation ("Parent"),  and
each  of  them,  as  the  sole  and  exclusive  attorneys  and  proxies  of  the
undersigned,  with full power of substitution  and  resubstitution,  to vote and
exercise all voting and related rights (to the full extent that the  undersigned
is  entitled  to do so) with  respect to all of the  Shares (as  defined in that
certain  Voting  Agreement of even date  herewith by and between  Parent and the
shareholders of Company party thereto,  including the  undersigned  (the "Voting
Agreement"))   that  now  are  or  hereafter  may  be  owned  of  record  and/or
beneficially  in  accordance  with the terms of this Proxy.  The Shares owned of
record and/or  beneficially by the undersigned  shareholder of Company as of the
date of this  Proxy  are  listed  on the  final  page of this  Proxy.  Upon  the
undersigned's  execution of this Proxy,  any and all prior  proxies given by the
undersigned  with  respect to any Shares and the matters in clauses (a), (b) and
(c) of the third  paragraph of this Proxy are hereby revoked and the undersigned
agrees not to grant any  subsequent  proxies  with  respect to the Shares  until
after the Expiration  Date (as defined  below).  Capitalized  terms used and not
defined  herein  have the  respective  meanings  ascribed  to them in the Voting
Agreement.

     This Proxy is coupled  with an  interest  and is  granted  pursuant  to the
Voting  Agreement and is granted in  consideration  of Parent entering into that
certain Combination Agreement (the "Combination Agreement"), among Parent, Orion
Exchangeco,  Ltd.  and Company  pursuant to which Parent will acquire all of the
outstanding share capital of Company (the  "Arrangement").  As used herein,  the
term  "Expiration  Date"  shall mean the  earlier to occur of (a) the  Effective
Time,  (b) after the date that  Parent  is no  longer  potentially  entitled  to
receive any payments upon termination of the Combination  Agreement  pursuant to
Section 8.3 of the Combination Agreement, (c) after payment of a termination fee
pursuant  to  Section  8.3(b) of the  Combination  Agreement  and (d) as between
Parent and the undersigned, agreement of Parent and the undersigned to terminate
the Voting Agreement with respect to the undersigned.

     The  attorneys  and  proxies  named  above,  and each of them,  are  hereby
authorized and empowered by the undersigned, at any time prior to the Expiration
Date, to act as the undersigned's  attorney and proxy to vote the Shares, and to
exercise all voting,  consent and similar rights of the undersigned with respect
to the Shares (including,  without limitation,  the power to execute and deliver
written  consents)  at every  meeting of the  shareholders  of Company,  however
called,  and in every action by written consent by the  shareholders of Company:
(a) in favor of the  approval  and adoption of the  Combination  Agreement,  the
Arrangement and all the transactions  contemplated by the Combination  Agreement
and otherwise in such manner as may be necessary to consummate the  Arrangement;
(b) except as otherwise  agreed to in writing in advance by Parent,  against any
action, proposal,  agreement or transaction that is intended or could reasonably
be  expected  to  result  in a breach of any  covenant,  obligation,  agreement,
representation or warranty of Company contained in the Combination  Agreement or
of the

<PAGE>

undersigned  contained  in the Voting  Agreement;  and (c)  against  any action,
proposal,  agreement  or  transaction,   including,  but  not  limited  to,  any
Acquisition Proposal (other than the Arrangement,  the Combination  Agreement or
the transactions  contemplated  thereby),  that could be reasonably  expected to
result in any of the conditions to Company's  obligations  under the Combination
Agreement  (whether or not  theretofore  terminated) not being fulfilled or that
could  reasonably  be expected  to impede,  interfere  with or  prevent,  delay,
postpone,   discourage  or  adversely  affect  the  Combination  Agreement,  the
Arrangement or the Voting Agreement.

     The  attorneys  and proxies  named above may not exercise this Proxy on any
other matter except as provided above. The undersigned  Shareholder may vote the
Shares on all other matters.

     (ii) The Share Payment shall be calculated based on the following formula:

                        W    =    X-Y
                                 -----
                                   Z

                    Where:         W =   The number of Parent Common Shares (for
                                         Electing Shareholders who are not
                                         Canadian Residents) or Exchangeable
                                         Shares (for Electing Shareholders who
                                         are Canadian Residents) issuable to the

Any Company  Shareholder  may elect for any one (but only one) of the  elections
referred  to in section  (c),  (d) or (e) above at any time  until the  Election
Deadline by executing and delivering a Letter of Transmittal  and Election Form.
Any Company Shareholder who is not a resident of Canada who has not made such an
election  prior to the  Election  Deadline  shall be deemed to have  elected  to
receive  Parent  Common  Shares  pursuant  to  section  (c) above.  Any  Company
Shareholder  who is a resident of Canada who has not made such an election prior
to the Election Deadline shall be deemed to have elected to receive Exchangeable
Shares pursuant to (e) above.

(2)  (a)  Each Company Stock Option that becomes  exercisable as a result of the
          Arrangement,  notwithstanding  any  contingent  vesting  provisions to
          which it might  otherwise  have  been  subject,  shall be deemed to be
          conditionally  vested and exercisable  only as part of the Arrangement
          unless  otherwise  agreed to by the holder of the Company Stock Option
          and the Parent.

     (b)  Each holder of a Company Stock Option (including,  without limitation,
          Company Stock Options  referred to in  subparagraph  (a)) may elect to
          conditionally  exercise one or more Company  Stock  Options as part of
          the  Arrangement  by delivering  to the  Depositary on or prior to the
          Election  Deadline  (i) a notice of the  conditional  exercise of such
          holder's Company Stock Options  indicating whether the holder elects a
          "Cash Exercise" or a "Cashless  Exercise" and (ii) a validly completed
          Letter of Transmittal  and Election Form electing  whether such holder
          wishes to receive Parent Shares, Exchangeable Shares or Per Share Cash
          Consideration   pursuant   to   Sections   2.2(1)(c),   (d)  or   (e),
          respectively,  hereof in exchange for the Company Common Shares issued
          to or received by the holder pursuant to the exercise of such holder's
          Company Stock Options.

     (c)  Each "Cash Exercise" shall be accompanied by a certified check or bank
          draft in an amount equal to the product  obtained by  multiplying  the
          number of Common  Shares in respect of which the Company  Stock Option
          is conditionally  exercised (the "Number of Options Exercised") by the
          exercise price per Company Stock Option (the "Exercise Price"). In the
          event of a "Cashless Exercise",  the holder shall transfer the Company
          Stock  Option to the Company in exchange  for  Company  Common  Shares
          using the following formula:

                        X    =    Y(A-B)
                                  -----
                                    A

                    Where:         X =   The number of shares of Company Common
                                         Shares to be issued to the Company

                                   Y =   The number of Company Common Shares
                                         under the holder's Company Stock Option
                                         with respect to which such option is
                                         exercised

                                   A =   The product of 0.75 multiplied by the
                                         weighted average closing trading price

                                         dollars, converted into U.S. Dollars
                                         based on the noon buying rates in New
                                         York City for cable transfers payable

                                         Deadline.

All  fractional  Company  Common  Shares  issuable  pursuant to the  exercise of
Company  Stock  Options  shall be rounded down to the next whole  share,  and no
consideration shall be paid in respect of such fraction.

     (d)  Any  holder of an "in the money"  option  who fails to elect  shall be
          deemed to have elected for a "Cashless  Exercise"  and to receive,  in
          exchange for the Company Common Shares issued or received  pursuant to
          the transfer of each Company Stock Option to the Company, Exchangeable
          Shares (if a Canadian  resident)  or Parent  Shares (if not a Canadian
          resident).

     (e)  At the Effective  Time,  every Company Stock Option which has not been
          exercised or deemed to have been exercised  shall be deemed  cancelled
          and each of the  Company  Stock  Option  Plans shall be deemed to have
          been terminated.

(3)  The names of the  Holders  of the  Company  Common  Shares  transferred  to
     Parentco  or  Exchangeco  pursuant  to sections  2.2(1)(c),  2.2(1)(d)  and
     2.2(1)(e)  shall be  removed  from the  applicable  register  of Holders of
     Company  Common Shares and added to the  applicable  register of holders of
     Parent Common Shares and/or  Exchangeable  Shares,  as the case may be, and
     Exchangeco shall be recorded as the registered Holder of the Company Common
     Shares so  exchanged  and  shall be  deemed to be the legal and  beneficial
     owner thereof.

(4)  Coincident  with the share  exchanges  set out in  sections  2.2(1)(c)  and
     2.2(1)(e),  Parent and Exchangeco  shall execute the Support  Agreement and
     Parent,  Exchangeco  and the Trustee  shall execute the Voting and Exchange
     Trust  Agreement and Parent shall issue to and deposit with the Trustee the
     Special Voting Share, in consideration of the payment to Parent of US$1.00,
     to be thereafter held of record by the Trustee as trustee for and on behalf
     of, and for the use and benefit of, the holders of the Exchangeable  Shares
     in accordance with the Voting and Exchange Trust  Agreement.  All rights of
     holders  of  Exchangeable  Shares  under  the  Voting  and  Exchange  Trust
     Agreement  shall be received by them as part of the property  receivable by
     them under section 2.2(1)(e), in exchange for the Company Common Shares for
     which they were exchanged.

2.3  Tax Election

Each beneficial owner of Company Common Shares who is a Canadian Resident (other
than any such owner who is exempt from tax under Part I of the ITA), and who has
validly  elected or deemed to have  elected  (or for whom the holder has validly
elected on such beneficial owner's

<PAGE>

                                      -11-

behalf) to receive  consideration  that  includes  Exchangeable  Shares shall be
entitled to make an income tax election  pursuant to subsection 85(1) of the ITA
or, if such beneficial owner is a partnership,  subsection 85(2) of the ITA (and
in each case, where applicable,  the corresponding  provisions of any applicable
provincial  income tax legislation)  with respect to the transfer of its Company
Common  Shares to  Exchangeco  by providing  two signed  copies of the necessary
prescribed  election  form(s) to the  Depositary  within 90 days  following  the
Effective  Date, duly completed with the details of the number of Company Common
Shares  transferred  and the applicable  agreed amounts for the purposes of such
elections.  Thereafter, subject to the election forms being correct and complete
and complying with the provisions of the ITA (or the corresponding provisions of
any applicable  provincial income tax legislation),  the forms will be signed by
Exchangeco and returned to such  beneficial  owner of Company Common Shares,  as
applicable,  within 30 days  after the  receipt  thereof by the  Depositary  for
filing  with the Canada  Revenue  Agency (or the  applicable  provincial  taxing
authority) by such beneficial owner.  Exchangeco will not be responsible for the
proper  completion of any election form and, except for Exchangeco's  obligation
to return duly  completed  election  forms which are received by the  Depositary
within 90 days of the Effective  Date,  within 30 days after the receipt thereof
by the Depositary, Exchangeco will not be responsible for any taxes, interest or
penalties  resulting  from the failure by a beneficial  owner of Company  Common
Shares to properly  complete or file the  election  forms in the form and manner
and within the time prescribed by the ITA (or any applicable  provincial  income
tax  legislation).  In its sole  discretion,  Exchangeco  may choose to sign and
return an election form received by the  Depositary  more than 90 days following
the Effective Date, but Exchangeco will have no obligation to do so.

2.4  Adjustments 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 Parent Common Shares or Company Common Shares, other
than stock dividends paid in lieu of ordinary course dividends),  consolidation,
reorganization,  recapitalization  or other like change  with  respect to Parent
Common  Shares  or  Company  Common  Shares  occurring  after  the  date  of the
Combination Agreement and prior to the Effective Time.

                                RIGHTS OF DISSENT

3.1  Rights of Dissent

Holders of Company Common Shares may exercise  rights of dissent 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  Rights") 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 Company  not later than 5:00 p.m.  (Vancouver  time) on
the Business Day preceding the Company Meeting. Holders of Company Common Shares
who duly exercise such rights of dissent and who:

     (a)  are  ultimately  determined  to be  entitled to be paid fair value for
          their Company Common Shares,  shall be deemed to have transferred such
          Company Common

<PAGE>

                                      -12-

          Shares to Exchangeco  immediately prior to the Effective Time, without
          any further act or  formality,  and free and clear of any lien,  claim
          and  encumbrance,  and  such  shares  shall  be  cancelled  as of  the
          Effective Time, or

     (b)  are ultimately  determined not to be entitled,  for any reason,  to be
          paid fair value for their Company  Common  Shares,  shall be deemed to
          have   participated  in  the  Arrangement  on  the  same  basis  as  a
          non-dissenting  holder of  Company  Common  Shares  who did not make a
          valid election to receive Exchangeable Shares and shall receive Parent
          Common Shares in exchange for their Company Common Shares on the basis
          determined in accordance with section 2.2(1)(c) above;

but in no case shall Parent,  Callco,  Exchangeco,  the  Depositary or any other
Person be required  to  recognize  such  Dissenting  Shareholders  as holders of
Company Common Shares after the Effective Time, and the names of such Dissenting
Shareholders  shall be deleted from the  registers of holders of Company  Common
Shares at the Effective Time.

4.1  Issuance of Certificates Representing Exchangeable Shares

At or promptly  after the  Effective  Time,  Exchangeco  shall  deposit with the
Depositary,  for the  benefit of the Holders of Company  Common  Shares who will
receive  Exchangeable  Shares in connection with the  Arrangement,  certificates
representing that number of whole  Exchangeable  Shares to be delivered pursuant
to section  2.2(1)(e).  Upon surrender to the Depositary for  cancellation  of a
certificate which  immediately  prior to the Effective Time represented  Company
Common  Shares  which  were   exchanged  for   Exchangeable   Shares  under  the
Arrangement,  together with such other  documents and  instruments as would have
been required to effect the transfer of the Company Common Shares under the CBCA
and the bylaws of Exchangeco  and such other  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 4.3 and any cash in lieu of fractional  Exchangeable  Shares
pursuant to section  4.4, in each case,  less any amounts  withheld  pursuant to
section 4.8), and the  certificate so surrendered  shall forthwith be cancelled.
In the event of a transfer of ownership of Company  Common  Shares which was not
registered in the transfer  records of Company,  a certificate  representing the
proper number of Exchangeable  Shares may,  subject to section 2.2, be issued to
the transferee if the certificate  which immediately prior to the Effective Time
represented Company Common Shares which Company Common Shares were exchanged for
Exchangeable  Shares  under the  Arrangement,  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  one or more  outstanding
Company   Common  Shares  which  Company   Common  Shares  were   exchanged  for
Exchangeable  Shares under the  Arrangement,  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

<PAGE>

                                      -13-

4.1,  (ii) a cash  payment  in lieu of any  fractional  Exchangeable  Shares  as
contemplated  by section 4.4 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  4.3,  in each case,  less any
amounts withheld pursuant to section 4.8.

4.2  Exchange of Certificates for Parent Common Shares

At or promptly after the Effective Time,  Exchangeco  shall deposit or cause the
deposit with the  Depositary,  for the benefit of the Holders of Company  Common
Shares who will receive  Parent Common Shares on the  Arrangement,  certificates
representing that number of whole Parent Common Shares to be delivered  pursuant
to section  2.2(1)(c) or section  2.2(1)(g),  in the event the Total Cash Amount
exceeds the Maximum Cash Consideration, as the case may be, upon the exchange of
Company Common Shares.  Upon surrender to the Depositary for  cancellation  of a
certificate  which  immediately  prior to the Effective Time  represented one or
more Company  Common Shares which were  exchanged for Parent Common Shares under
the  Arrangement,  together with such other  documents and  instruments as would
have been required to effect the transfer of the Company Common Shares under the
CBCA and the bylaws of Exchangeco  and such other  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 Parent Common Shares which such
Holder has the right to receive  (together  with any dividends or  distributions
with respect thereto  pursuant to section 4.3 and any cash in lieu of fractional
Parent  Common Shares  pursuant to section 4.4 or otherwise  pursuant to section
2.2(1),  less any amounts withheld pursuant to section 4.8), and the certificate
so  surrendered  shall  forthwith  be  cancelled.  In the event of a transfer of
ownership  of Company  Common  Shares which was not  registered  in the transfer
records of  Company,  a  certificate  representing  the proper  number of Parent
Common  Shares may,  subject to section 2.2, be issued to the  transferee if the
certificate which  immediately  prior to the Effective Time represented  Company
Common  Shares which  Company  Common  Shares were  exchanged  for Parent Common
Shares under the Arrangement, is presented to the Depositary, accompanied by all
documents  reasonably  required to  evidence  and effect  such  transfer.  Until
surrendered  as  contemplated  by  this  section  4.2,  each  certificate  which
immediately  prior to the Effective  Time  represented  one or more  outstanding
Company  Common  Shares which Company  Common  Shares were  exchanged for Parent
Common  Shares  under the  Arrangement,  shall be deemed at all times  after the
Effective  Time to represent only the right to receive upon such surrender (i) a
certificate  representing  the  Parent  Common  Shares as  contemplated  by this
section 4.2, (ii) a cash payment in lieu of  fractional  Parent Common Shares as
contemplated by section 4.4 or otherwise  pursuant to section 2.2(1),  and (iii)
any  dividends  or  distributions  with a record date after the  Effective  Time
theretofore paid or payable with respect to Parent Common Shares as contemplated
by section 4.3, in each case, less any amounts withheld pursuant to section 4.8.

4.3  Distributions with Respect to Unsurrendered Certificates

No dividends or other  distributions  declared or made after the Effective  Time
with respect to  Exchangeable  Shares or Parent Common Shares with a record date
after  the  Effective  Time  shall by paid to the  Holder  of any  unsurrendered
certificate   which   immediately   prior  to  the  Effective  Time  represented
outstanding Company Common Shares which were exchanged pursuant to

<PAGE>

                                      -14-

section  2.2(1)(c),  2.2(1)(e)  or  2.2(1)(g),  as the case may be,  and no cash
payment in lieu of fractional  shares shall be paid to any such holder  pursuant
to section 4.4, unless and until the holder of such certificate  shall surrender
such  certificate  in  accordance  with  section 4.1 or 4.2, as the case may be.
Subject to applicable law, at the time of such surrender of any such certificate
(or, in the case of clause (iii) below, at the appropriate  payment date), there
shall be paid to the  Holder of the  certificates  representing  Company  Common
Shares  without  interest,  (i) the  amount  of any  cash  payable  in lieu of a
fractional share to which such holder is entitled  pursuant to section 4.4, (ii)
the amount of  dividends  or other  distributions  with a record  date after the
Effective  Time  theretofore  paid with  respect to the  Exchangeable  Shares or
Parent  Common  Shares,  as the case may be, to which  such  holder is  entitled
pursuant  hereto  and (iii) to the extent not paid  under  clause  (ii),  on the
appropriate  payment date, the amount of dividends or other distributions with a
record date after the Effective Time but prior to surrender and the payment date
subsequent  to surrender  payable with  respect to such  Exchangeable  Shares or
Parent Common Shares.

4.4  No Fractional Shares

No certificates representing fractional Exchangeable Shares or fractional Parent
Common Shares shall be issued upon the  surrender  for exchange of  certificates
pursuant to section 4.1 or 4.2 and no  dividend,  stock split or other change in
the  capital  structure  of  Exchangeco  or  Parent  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 Exchangeco or Parent.  In
lieu of any such  fractional  securities,  each Person  otherwise  entitled to a
fractional  interest in an  Exchangeable  Share or Parent  Common  Share will be
entitled to receive a cash  payment  equal to such  Person's pro rata portion of
the net proceeds  after  expenses  received by the  Depositary  upon the sale of
whole  shares  representing  an  accumulation  of all  fractional  interests  in
Exchangeable  Shares or Parent Common  Shares,  as the case may be, to which all
such  Persons  would  otherwise  be  entitled.  The  Depositary  will  sell such
Exchangeable  Shares by  private  sale  (including  by way of sale  through  the
facilities  of any stock  exchange upon which the  Exchangeable  Shares are then
listed) as soon as reasonably  practicable  following the  Effective  Date.  The
aggregate net proceeds  after  expenses of such sale will be  distributed by the
Depositary,  pro rata in relation to the  respective  fractions,  among  Persons
otherwise entitled to receive fractional  interests in Exchangeable  Shares. The
Depositary  will  sell  such  Parent  Common  Shares  on the  NASDAQ  as soon as
reasonably  practicable following the Effective Date. The aggregate net proceeds
after expenses of such sale will be distributed by the  Depositary,  pro rata in
relation  to the  respective  fractions,  among  Persons  otherwise  entitled to
receive fractional interests in Parent Common Shares.

A holder of an  Exchangeable  Share shall not be  entitled to any  fraction of a
Parent Common Share upon the exercise by Callco of the Liquidation Call Right or
the  Redemption  Call Right or upon the  exercise  by Parent of the Parent  Call
Right and no certificates  representing  any such  fractional  interest shall be
issued and such holder otherwise entitled to a fractional  interest will receive
for such fractional  interest from Callco or Parent,  as the case may be, on the
designated  payment  date to the extent not paid by  Exchangeco  a cash  payment
equal to such fractional interest multiplied by the Current Market Price.

4.5  Lost Certificates

In the event any  certificate  which  immediately  prior to the  Effective  Time
represented one or more  outstanding  Company Common Shares which Company Common
Shares were then subsequently  exchanged pursuant to section 2.2 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,
certificates  representing  Exchangeable  Shares or Parent  Common Shares (and a
cheque for any  dividends or  distributions  with  respect  thereto and any cash

Shares are to be issued shall, as a condition precedent to the issuance thereof,
give a bond  satisfactory  to  Company,  Exchangeco,  Callco,  Parent  and their
respective transfer agents in such sum as Company, Exchangeco,  Callco or Parent
may direct or otherwise indemnify Company, Exchangeco, Callco and Parent and the
Depositary in a manner  satisfactory to Company,  Exchangeco,  Callco and Parent
against any claim that may be made against Company, Exchangeco, Callco or Parent
with respect to the certificate alleged to have been lost, stolen or destroyed.

4.6  Cheques

At or  promptly  after the  Effective  Time,  Exchangeco  shall  deliver  to the
Depositary, for the benefit of holders of Company Common Shares who will receive
cash on the Arrangement, an amount of cash sufficient to pay the amounts payable
in cash by  Exchangeco  pursuant to section  2.2(1)(d).  Upon  surrender  to the
Depositary  for  cancellation  of a certificate  for one or more Company  Common
Shares,  the  Depositary  shall pay to such  holder the  amount to such  Company
Shareholder pursuant to section 2.2(1)(d) (less any amounts withheld pursuant to
section 4.8).

Effective  Date shall  cease to  represent  a claim or  interest  of any kind or
nature as a shareholder of Company,  Exchangeco,  Callco or Parent or a right to
receive  any other  amount  pursuant  to this  Arrangement.  On such  date,  the
Exchangeable  Shares  or Parent  Common  Shares  (or cash in lieu of  fractional
interests  therein or otherwise,  as provided in section 4.4 or cash not paid by
the  Depositary  pursuant  to  section  4.6) to which the  former  holder of the
certificate  referred to in the preceding sentence was ultimately entitled shall
be deemed to have been  surrendered  for no  consideration  to Parent or Callco.
None of Parent, Company, Callco, Exchangeco or the Depositary shall be liable to
any person in respect of any  Exchangeable  Shares or Parent  Common  Shares (or

Exchangeco,  Callco,  Parent and the Depositary  shall be entitled to deduct and
withhold from any dividend or consideration  otherwise  payable to any holder of
Company Common Shares,  Parent Common Shares or Exchangeable Shares such amounts

and  withhold  with respect to such  payment  under the ITA,  the United  States

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 entitled to be deducted or withheld from any payment to a holder  exceeds the
cash portion of the consideration  otherwise payable to the holder,  Exchangeco,
Callco,  Parent 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 Exchangeco,  Callco,  Parent or the Depositary,  as the case
may be, to enable it to comply with such deduction or withholding requirement or
entitlement and Exchangeco,  Callco,  Parent or the Depositary  shall notify the
holder  thereof  and  remit to such  holder  any  unapplied  balance  of the net
proceeds of such sale.

4.9  Termination of Depositary

demand therefor,  and holders of certificates  previously  representing  Company
Common  Shares who have not  theretofore  complied with Sections 4.1, 4.2 or 4.6
shall  thereafter  look only to  Exchangeco  for  payment  of any claim to cash,

dividends or distributions, if any, in respect thereof.

                                   ARTICLE 5

             CERTAIN RIGHTS OF CALLCO TO ACQUIRE EXCHANGEABLE SHARES

5.1  Callco Liquidation Call Right

In addition to Callco's rights contained in the Exchangeable  Share  Provisions,
including,  without limitation, the Retraction Call Right, Callco shall have the
following rights in respect of the Exchangeable Shares:

(1)  Callco shall have the overriding right (the "Liquidation  Call Right"),  in
     the event of and notwithstanding the proposed  liquidation,  dissolution or
     winding-up of Exchangeco  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 any holder of Exchangeable Shares which is
     Parent or an Affiliate of Parent) on the Liquidation  Date all but not less
     than all of the Exchangeable  Shares held by each such holder on payment by
     Callco  to each  such  holder  of an amount  per  Exchangeable  Share  (the
     "Liquidation

<PAGE>

                                      -17-

     Call Purchase Price") equal to the sum of (i) the Current Market Price of a
     Parent Common Share on the last Business Day prior to the Liquidation Date,
     which  shall be  satisfied  in full by Callco  delivering  or causing to be
     delivered to such holder one Parent  Common  Share,  plus (ii) any Dividend
     Amount.  In the event of the  exercise  of the  Liquidation  Call  Right by
     Callco,  each  holder  (other  than  Parent  and its  Affiliates)  shall be
     obligated to sell all the Exchangeable  Shares held by the holder to Callco
     on  the  Liquidation  Date  on  payment  by  Callco  to the  holder  of the
     Liquidation  Call Purchase Price for each such share,  and Exchangeco shall
     have no  obligation  to pay any  Liquidation  Amount to the holders of such
     shares so purchased by Callco.

(2)  To exercise the  Liquidation  Call Right,  Callco must notify  Exchangeco's
     transfer  agent  (the  "Transfer  Agent"),  as  agent  for the  Holders  of
     Exchangeable  Shares, and Exchangeco of Callco'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 Exchangeco and at least
     five  Business  Days  before  the  Liquidation  Date  in  the  case  of  an
     involuntary  liquidation,  dissolution  or  winding-up of  Exchangeco.  The
     Transfer Agent will notify the holders of Exchangeable Shares as to whether
     or not Callco has exercised the Liquidation  Call Right forthwith after the
     expiry of the period  during which the same may be exercised by Callco.  If
     Callco exercises the Liquidation Call Right,  then on the Liquidation Date,
     Callco  will  purchase  and all of the  Holders  (other than Parent and its
     Affiliates)  will  sell all of the  Exchangeable  Shares  held by each such
     Holder then  outstanding  for a price per  Exchangeable  Share equal to the
     Liquidation Call Purchase Price.

(3)  For the  purposes of  completing  the purchase of the  Exchangeable  Shares
     pursuant to the Liquidation Call Right, Callco shall deposit or cause to be
     deposited  with the  Transfer  Agent,  on or before the  Liquidation  Date,
     certificates  representing  the  aggregate  number of Parent  Common Shares
     deliverable  by Callco and a cheque or cheques of Callco  payable at par at
     any branch of the bankers of Callco  representing  the  aggregate  Dividend
     Amount, if any, in payment of the total Liquidation Call Purchase Price for
     all Holders of Exchangeable  Shares (other than Parent and its Affiliates),
     less any amounts withheld pursuant to section 4.8. Provided that Callco has
     complied  with  the  immediately  preceding  sentence,  on  and  after  the
     Liquidation Date, each Holder of Exchangeable Shares (other than Parent and
     its Affiliates) shall cease to be a Holder of Exchangeable Shares and shall
     not be entitled to exercise  any of the rights of a Holder of  Exchangeable
     Shares  (including,  without  limitation,  any rights  under the Voting and
     Exchange  Trust  Agreement),  other  than  the  right to  receive,  without
     interest,  its  proportionate  part of the total  Liquidation Call Purchase
     Price payable by Callco upon  presentation  and surrender by such 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 Parent  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 CBCA and the by-laws of Exchangeco  and such
     additional   documents,   instruments  and  payments  (including,   without
     limitation,   any  applicable  Stamp  Taxes)  as  the  Transfer  Agent  may
     reasonably  require,   the  holder  of  such  surrendered   certificate  or
     certificates shall be entitled to receive in exchange

<PAGE>

                                      -18-

     therefor,  and the Transfer Agent on behalf of Callco shall deliver to such
     holder  certificates  representing  the Parent  Common  Shares to which the
     holder is entitled and a cheque or cheques of Callco  payable at par at any
     branch of the  bankers of Callco in payment of the  remaining  portion,  if
     any,  of the  total  Liquidation  Call  Purchase  Price,  less any  amounts
     withheld  pursuant  to  section  4.8.  If  Callco  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 Exchangeco in
     connection  with the  liquidation,  dissolution or winding-up of Exchangeco
     pursuant to Article 5 of the Exchangeable Share Provisions.

5.2  Callco Redemption Call Right

In addition to Callco's rights contained in the Exchangeable  Share  Provisions,
including,  without limitation, the Retraction Call Right, Callco shall have the
following rights in respect of the Exchangeable Shares:

(1)  Callco  shall have the  overriding  right (the  "Redemption  Call  Right"),
     notwithstanding  the  proposed  redemption  of the  Exchangeable  Shares by
     Exchangeco  pursuant to Article 7 of the Exchangeable Share Provisions,  to
     purchase  from all but not less  than all of the  holders  of  Exchangeable
     Shares (other than any Holder of Exchangeable  Shares which is Parent or an
     Affiliate  of Parent) on the  Redemption  Date all but not less than all of
     the  Exchangeable  Shares  held by each such Holder on payment by Callco to
     each  Holder of an amount  per  Exchangeable  Share (the  "Redemption  Call
     Purchase  Price")  equal to the sum of (i) the  Current  Market  Price of a
     Parent Common Share on the last Business Day prior to the Redemption  Date,
     which  shall be  satisfied  in full by Callco  delivering  or causing to be
     delivered to such holder one Parent  Common  Share,  plus (ii) any Dividend
     Amount.  In the  event of the  exercise  of the  Redemption  Call  Right by
     Callco,  each holder shall be obligated to sell all the Exchangeable Shares
     held by the Holder to Callco on the Redemption Date on payment by Callco to
     the Holder of the Redemption  Call Purchase Price for each such share,  and
     Exchangeco  shall  have no  obligation  to redeem,  or to pay any  Dividend
     Amount in respect of, such shares so purchased by Callco.

(2)  To exercise  the  Redemption  Call Right,  Callco must notify the  Transfer
     Agent, as agent for the holders of Exchangeable  Shares,  and Exchangeco of
     Callco'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 a Parent Control  Transaction,  an Exchangeable Share Voting Event or an
     Exempt  Exchangeable  Share  Voting  Event,  in which case Callco  shall so
     notify the Transfer Agent and Exchangeco on or before the Redemption  Date.
     The Transfer Agent will notify the Holders of the Exchangeable Shares as to
     whether or not Callco has exercised  the  Redemption  Call Right  forthwith
     after the expiry of the period  during  which the same may be  exercised by
     Callco.  If Callco  exercises the Redemption  Call Right, on the Redemption
     Date,  Callco will  purchase and all of the Holders  (other than Parent and
     its Affiliates) will sell all of the Exchangeable  Shares held by each such
     Holder then  outstanding  for a price per  Exchangeable  Share equal to the
     Redemption Call Purchase Price.

<PAGE>

                                      -19-

(3)  For the  purposes of  completing  the purchase of the  Exchangeable  Shares
     pursuant to the Redemption Call Right,  Callco shall deposit or cause to be
     deposited  with the  Transfer  Agent,  on or before  the  Redemption  Date,
     certificates  representing  the  aggregate  number of Parent  Common Shares
     deliverable  by Callco and a cheque or cheques of Callco  payable at par at
     any branch of the bankers of Callco  representing  the  aggregate  Dividend
     Amount,  if any, in payment of the total Redemption Call Purchase Price for
     all Holders of Exchangeable  Shares (other than Parent and its Affiliates),
     less any amounts withheld pursuant to section 4.8. Provided that Callco has
     complied  with  the  immediately  preceding  sentence,  on  and  after  the
     Redemption Date each Holder of  Exchangeable  Shares (other than Parent and
     its Affiliates)  shall cease to be a Holder of the Exchangeable  Shares and
     shall  not be  entitled  to  exercise  any  of the  rights  of  Holders  of
     Exchangeable Shares (including,  without  limitation,  any rights under the
     Voting and  Exchange  Trust  Agreement),  other than the right to  receive,
     without  interest,  its  proportionate  part of the total  Redemption  Call
     Purchase  Price payable by Callco upon  presentation  and surrender by such
     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 Parent 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 CBCA and the by-laws of Exchangeco  and such
     additional   documents,   instruments  and  payments  (including,   without
     limitation,   any  applicable  Stamp  Taxes)  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  Callco  shall   deliver  to  such  Holder
     certificates  representing  the Parent Common Shares to which the holder is
     entitled and a cheque or cheques of Callco  payable at par at any branch of
     the bankers of Callco in payment of the remaining  portion,  if any, of the
     total Redemption Call Purchase Price, less any amounts withheld pursuant to
     section 4.8. If Callco 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 Exchangeco in connection  with the
     redemption  of  the  Exchangeable  Shares  pursuant  to  Article  7 of  the
     Exchangeable  Share Provisions,  together with accrued and unpaid dividends
     on such Exchangeable  Shares held by the holder on any dividend record date
     prior to the Redemption Date.

5.3  Parent Call Right

(1)  Parent will have the right (the "Parent  Call  Right") to  purchase,  or to
     cause Callco to purchase,  from all but not less than all of the holders of
     Exchangeable Shares (other than Parent and its Affiliates) on the Change in
     Law Exchange Date all but not less than all of the Exchangeable Shares held
     by each such holder on payment by Parent or Callco,  as the case may be, of
     an amount per  Exchangeable  Share (the "Parent Call Purchase Price") equal
     to the sum of (i) the Current  Market Price of a Parent Common Share on the
     last Business Day prior to the Change in Law Exchange Date,  which shall be
     satisfied  in full by Parent  delivering  or  causing to be  delivered,  or
     Callco  causing to be  delivered,  to such holder one Parent  Common Share,
     plus, (ii) any Dividend Amount.  In the event of the exercise of the Parent
     Call Right by Parent each Holder (other than Parent and its

<PAGE>

                                      -20-

     Affiliates) shall be obligated to sell all of the Exchangeable  Shares held
     by such  Holder to Parent or  Callco,  as the case may be, on the Change in
     Law  Exchange  Date on payment by Parent or Callco,  as the case may be, to
     the holder of the Parent Call Purchase Price for each such share.

(2)  To  exercise  the Parent Call  Right,  (i) Parent must notify the  Transfer
     Agent, as agent for the holders of Exchangeable  Shares,  and Exchangeco of
     Parent's  intention to exercise or cause  Callco to exercise  such right at
     least 45 days  before  the  Business  Day on  which  the  purchase  of such
     Exchangeable  Shares shall occur (the  "Change in Law  Exchange  Date") and
     such  notice  shall  specify  whether  Parent or Callco  will  effect  such
     purchase, and (ii) Parent must deliver to the Trustee an opinion in writing
     signed by Canadian  counsel to Parent  (which  counsel  must be  reasonably
     acceptable to the Trustee)  stating that since the Effective Date there has
     been a  change  to  the  ITA  and  any  applicable  provincial  income  tax
     legislation   to  the  effect  that  the  sale  by  beneficial   owners  of
     Exchangeable Shares (other than Parent and its Affiliates) who are Canadian
     Residents and who hold their  Exchangeable  Shares as capital  property for
     the  purposes  of  the  ITA  and  any  applicable   provincial  income  tax
     legislation of Exchangeable Shares to Parent or Callco, as the case may be,
     pursuant  to  the  Parent  Call  Right  will  qualify  as  a  tax  deferred
     transaction  for purposes of the ITA and any applicable  provincial  income
     tax legislation. The Transfer Agent will notify the holders of Exchangeable
     Shares that the Parent Call Right has been  exercised  by Parent or Callco.
     If Parent  exercises  the  Parent  Call  Right,  then on the  Change in Law
     Exchange  Date Parent or Callco,  as the case may be, will purchase and all
     of the Holders (other than Parent and its Affiliates)  will sell all of the
     Exchangeable  Shares held by such Holders then  outstanding for a price per
     share equal to the Parent Call Purchase Price.

(3)  For the  purposes of  completing  the purchase of the  Exchangeable  Shares
     pursuant to the Parent Call  Right,  Parent or Callco,  as the case may be,
     shall  deposit or cause to be  deposited  with the  Transfer  Agent,  on or
     before the  Change in Law  Exchange  Date,  certificates  representing  the
     aggregate  number of Parent Common Shares  deliverable by Parent or Callco,
     as the case may be, and a cheque or  cheques  of Parent or  Callco,  as the
     case may be,  payable  at par at any  branch  of the  bankers  of Parent or
     Callco, as the case may be,  representing the aggregate Dividend Amount, if
     any, in payment of the total Parent Call Purchase  Price for all Holders of
     Exchangeable Shares (other than Parent and its Affiliates) less any amounts
     withheld  pursuant to section 4.8.  Provided that Parent or Callco,  as the
     case may be, has complied with the immediately  preceding sentence,  on and
     after the Change in Law Exchange Date, each Holder of  Exchangeable  Shares
     (other  than  Parent  and its  Affiliates)  shall  cease to be a Holder  of
     Exchangeable Shares and shall not be entitled to exercise any of the rights
     of a Holder of Exchangeable  Shares  (including,  without  limitation,  any
     rights under the Voting and Exchange Trust  Agreement) other than the right
     to receive,  without interest,  its proportionate  part of the total Parent
     Call Purchase  Price payable by Parent or Callco,  as the case may be, upon
     presentation and surrender by such Holder of certificates  representing the
     Exchangeable  Shares held by such holder and the Holder  shall on and after
     the Change in Law Exchange Date be  considered  and deemed for all purposes
     to be the Holder of the Parent 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

<PAGE>

                                      -21

     documents  and  instruments  as may be  required  to effect a  transfer  of
     Exchangeable  Shares under the CBCA and the by-laws of Exchangeco  and such
     additional   documents,   instruments  and  payments  (including,   without
     limitation,   any  applicable  Stamp  Taxes)  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 Parent or  Callco,  as the case may be,  shall
     deliver to such holder,  certificates representing the Parent Common Shares
     to which  the  holder is  entitled  and a cheque  or  cheques  of Parent or
     Callco,  as the case may be, payable at par at any branch of the bankers of
     Parent or Callco, as the case may be, in payment of the remaining  portion,
     if any,  of the  Parent  Call  Purchase  Price  less any  amounts  withheld
     pursuant to section 4.8 hereof.

5.4  Exchange Put Right

Upon and subject to the terms and conditions contained in the Exchangeable Share
Provisions  and the  Voting  Trust and  Exchange  Trust  Agreement,  a Holder of
Exchangeable Shares shall have the Exchange Put Right.

6.1  Amendments to Plan of Arrangement

(1)  Company  reserves  the right to amend,  modify or  supplement  this Plan of

     that Parent shall have  consented  thereto) with or without any other prior
     notice or  communication,  and if so proposed  and  accepted by the Persons
     voting at the Company Meeting  (subject to the  requirements of the Interim
     Order), shall become part of this Plan of Arrangement for all purposes.

     the reasonable  opinion of Parent, is of an administrative  nature required

     dividend  represented  thereby. No holder of an Exchangeable Share shall be
     entitled  to  recover  by  action  or  other  legal  process   against  the

     applicable to the payment of such dividends.

     discretion,  economic  equivalence  for the purposes of Section 3.1 hereof,

          acquire Parent Common Shares),  the relationship  between the exercise
          price of each such right,  option or warrant  and the  Current  Market
          Price of a Parent 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
          Parent of any Class  other than  Parent  Common  Shares,  any  rights,
          options or warrants  other than those  referred  to in Section  3.5(b)
          hereof,  any  evidences  of  indebtedness  of Parent or any  assets of
          Parent), the relationship between the fair market value (as determined
          by  the  Board  of  Directors)  of  such  property  to  be  issued  or
          distributed with respect to each  outstanding  Parent Common Share and
          the Current Market Price of a Parent Common Share;

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

     (e)  in all such cases, the general  taxation  consequences of the relevant
          event to beneficial  owners of Exchangeable  Shares to the extent that
          such  consequences  may differ from the taxation  consequences to such
          owners  determined  as if  they  owned  Parent  Common  Shares  at the
          relevant time as a result of differing tax treatment under the 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  beneficial  owners  of
          Exchangeable Shares).

                                   ARTICLE 4
                              CERTAIN RESTRICTIONS

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 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 the Exchangeable  Shares with respect to the payment of dividends
          or on any liquidation distribution or winding up of the Corporation or
          any other  distribution of all or  substantially  all of the assets of
          the Corporation; or

     (d)  issue any  Exchangeable  Shares or any other shares of the Corporation
          ranking  equally with, or superior to, the  Exchangeable  Shares other
          than pursuant to a shareholders rights plan adopted by the Corporation
          or by way of  stock  dividends  to the  holders  of such  Exchangeable
          Shares.

The  restrictions  in this  Article 4 shall not  apply if all  dividends  on the
outstanding  Exchangeable Shares corresponding to dividends declared and paid on
the Parent Common  Shares shall have been declared and paid on the  Exchangeable
Shares.

                                   ARTICLE 5
                           DISTRIBUTION ON LIQUIDATION

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,  subject
     to the  exercise  by  Callco of the  Liquidation  Call  Right,  a holder of
     Exchangeable  Shares  shall be  entitled,  subject to  applicable  law,  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 (the  "Liquidation  Amount")  equal to the sum of: (i) the
     Current  Market  Price of a Parent  Common  Share on the last  Business Day
     prior to the  Liquidation  Date,  which shall be  satisfied  in full by the
     Corporation delivering or causing to be delivered to such holder one Parent
     Common Share, and (ii) an amount equal to 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.

                                      -10-

5.2  On or promptly after the  Liquidation  Date,  and provided the  Liquidation
     Call Right has not been exercised by Callco,  the Corporation  shall pay or
     cause to be paid to the holders of the Exchangeable  Shares the Liquidation
     Amount 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 BCA and the Articles of the  Corporation and
     such additional  documents,  instruments and payments as the Transfer Agent
     and the Corporation may reasonably require, 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 the  Exchangeable  Shares.
     Payment of the total Liquidation Amount for such Exchangeable  Shares shall
     be made by  transferring  or causing to be  transferred  to each holder the
     Parent  Common Shares to which such holder is entitled and by delivering to
     such  holder,  at the  address of such holder  recorded in the  register of
     shareholders of the Corporation for the  Exchangeable  Shares or by holding
     for pick-up by such 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  certificates  representing  Parent Common Shares (which shares
     shall be 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 remaining
     portion,  if any, of the total  Liquidation  Amount (in each case, less any
     amounts  withheld on account of tax pursuant to Section 13.3). On and after
     the Liquidation Date, each holder of Exchangeable  Shares shall cease to be
     a holder of  Exchangeable  Shares and shall not be entitled to exercise any
     of the  rights  of a holder  of  Exchangeable  Shares  (including,  without
     limitation,  any rights  under the Voting and  Exchange  Trust  Agreement),
     other  than the  right  to  receive  its  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  holder  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
     transfer or cause to be issued or transferred  to, and deposited  with, the
     Depositary  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, such Liquidation Amount to be held
     by the  Depositary  as  trustee  for and on behalf  of, and for the use and
     benefit of, such  holders.  Upon such deposit  being made,  the rights of a
     holder of  Exchangeable  Shares  after  such  deposit  shall be  limited to
     receiving its proportionate  part of the total Liquidation  Amount for such
     Exchangeable Shares so deposited,  without interest, (in each case less any
     amounts  withheld  on account of tax  pursuant  to  Section  13.3)  against
     presentation and surrender of the certificates for the Exchangeable  Shares
     held by them in accordance with the foregoing provisions. Upon such payment
     or deposit of the total  Liquidation  Amount,  the holders of  Exchangeable
     Shares shall  thereafter  be  considered  and deemed for all purposes to be
     holders of the Parent 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

<PAGE>

                                      -11-

     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,  subject to
     the  exercise by Callco of the  Retraction  Call Right and  otherwise  upon
     compliance  with,  and  subject  to, 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 equal to the
     sum of: (i) the Current  Market Price of a Parent  Common Share on the last
     Business Day prior to the Retraction Date (the "Retraction  Price"),  which
     shall be satisfied in full by the  Corporation  delivering or causing to be
     delivered  to such  holder one Parent  Common  Share for each  Exchangeable
     Share presented and  surrendered by the holder,  and (ii) on the designated
     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 BCA and the Articles of the  Corporation and
     such additional  documents,  instruments and payments as the Transfer Agent
     and the  Corporation  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
          Callco  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 Callco in accordance  with the Retraction  Call Right on the
          terms and conditions set out in Section 6.3 hereof.

<PAGE>

                                      -12-

6.2  Subject  to the  exercise  by Callco of the  Retraction  Call  Right,  upon
     receipt by the Corporation or the Transfer Agent in the manner specified in
     Section 6.1 of a certificate  or  certificates  representing  the number of
     Retracted Shares, 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, the Corporation shall redeem the Retracted Shares effective at
     the close of business on the Retraction Date and shall transfer or cause to
     be issued or  transferred  to such holder the Parent Common Shares to which
     such holder is entitled and shall comply with Section 6.4 hereof. If only a
     part of the Exchangeable  Shares represented by any certificate is redeemed
     (or  purchased by Callco  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 Callco thereof and shall provide to Callco a copy
     of the Retraction  Request. In order to exercise the Retraction Call Right,
     Callco  must  notify the  Corporation  of its  determination  to do so (the
     "Callco Call Notice")  within five Business Days of  notification to Callco
     by the  Corporation  of the receipt by the  Corporation  of the  Retraction
     Request.  If Callco  does not so notify the  Corporation  within  such five
     Business  Day  period,  the  Corporation  will notify the holder as soon as
     possible  thereafter  that Callco will not  exercise  the  Retraction  Call
     Right.  If Callco delivers the Callco 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 Callco in accordance with the Retraction Call Right. In
     such  event,  the  Corporation  shall not redeem the  Retracted  Shares and
     Callco shall purchase from such holder and such holder shall sell to Callco
     on the  Retraction  Date the  Retracted  Shares for a  purchase  price (the
     "Purchase  Price") per share equal to the sum of: (i) the Retraction  Price
     per share,  which shall be satisfied in full by the Corporation  delivering
     or causing to be delivered to such holder one Parent Common Share, and (ii)
     on the  designated  payment  date  therefor,  to the extent not paid by the
     Corporation on or before the designated payment date therefor, any Dividend
     Amount.  To the extent that Callco pays the  Dividend  Amount in respect of
     the Retracted  Shares,  the Corporation shall no longer be obligated to pay
     any declared and unpaid dividends on such Retracted  Shares.  Provided that
     Callco has complied  with  Section 6.4 hereof,  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 Callco does not deliver a Callco 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 Callco,  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 register of shareholders 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

<PAGE>

                                      -13-

     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 Parent Common Shares
     (which shares shall be 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 Callco,  as applicable,  in an
     amount equal to declared and unpaid  dividends  or the  aggregate  Dividend
     Amount, as the case may be, 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 pursuant to Section  13.3,  and such delivery of
     such certificates and cheques on behalf of the Corporation or by Callco, 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 (including, without limitation, any rights under the Voting
     and  Exchange  Trust  Agreement),  other  than  the  right to  receive  its
     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 hereof, 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
     Callco shall  thereafter be a holder of the Parent Common Shares  delivered
     to it.

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 Callco 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 and
     the Trustee 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

<PAGE>

                                      -14-

     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 and that  Callco has not
     exercised the Retraction  Call Right with respect to the Retracted  Shares,
     the  holder  of such  Retracted  Shares  not  redeemed  by the  Corporation
     pursuant  to  Section  6.2 as a result of  solvency  requirements  or other
     provisions  of  applicable  law shall be deemed  by giving  the  Retraction
     Request to constitute  notice by the holder to the Trustee  instructing the
     Trustee to require  Parent to,  subject to  applicable  law,  purchase such
     Retracted  Shares  from such  holder on the  Retraction  Date or as soon as
     practicable  thereafter on payment by Parent 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 Callco shall be deemed to have been
     revoked.

                                   ARTICLE 7
              REDEMPTION OF EXCHANGEABLE SHARES BY THE CORPORATION

7.1  Subject to  applicable  law,  and  provided  Callco 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
     (other than any such shares then held by Parent or an  Affiliate of Parent)
     for an amount per share equal to the sum of: (i) the Current  Market  Price
     of a Parent 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 Parent  Common Share for each  Exchangeable  Share held by such holder,
     together with (ii) 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.

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 a Parent  Control
     Transaction,  an Exchangeable  Share Voting Event,  an Exempt  Exchangeable
     Share  Voting  Event or a Change in Tax  Law),  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 Callco 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 Parent Control
     Transaction,  an Exchangeable  Share Voting Event,  an Exempt  Exchangeable
     Share  Voting  Event or a Change  in Tax Law,  the  written  notice  of the
     redemption  by  the  Corporation  or  the  purchase  by  Callco  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

<PAGE>

                                      -15-

     Board of Directors 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 Callco of
     the Redemption Call Right, the Corporation shall pay or cause to be paid 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, less any amounts withheld on account of tax pursuant to Section 13.3,
     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 BCA
     and  the  Articles  of  the  Corporation  and  such  additional  documents,
     instruments  and payments as the  Transfer  Agent and the  Corporation  may
     reasonably  require.  Payment  of  the  total  Redemption  Price  for  such
     Exchangeable Shares, together with payment of such dividends, shall be made
     by  transferring  or causing to be issued or transferred to each holder the
     Parent  Common Shares to which such holder is entitled and by delivering to
     such  holder,  at the  address of such holder  recorded in the  register of
     shareholders of the Corporation for the  Exchangeable  Shares or by holding
     for pick-up by such 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  certificates  representing
     Parent Common  Shares (which shares shall be 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 pursuant to Section  13.3.  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  holders in
     respect thereof (including, without limitation, any rights under the Voting
     and  Exchange  Trust  Agreement),  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 transfer or cause to be issued or  transferred  to,
     and  deposited  with,  the  Depositary  named  in  such  notice  the  total
     Redemption  Price  for  and  the  full  amount  of  such  dividends  on the
     Exchangeable  Shares (except as otherwise  provided in this Section 7.3) 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, less
     any amounts  withheld  on account of tax  pursuant  to Section  13.3,  such
     Redemption  Price to be held by the Depositary as trustee for and on behalf
     of, and for the use and benefit of,

<PAGE>

                                      -16-

     such holders.  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, without interest, and when received
     by the Depositary,  all dividends and other  distributions  with respect to
     the Parent  Common  Shares to which such holder is  entitled  with a record
     date after the later of the date of such  deposit and the  Redemption  Date
     and before the date of transfer of such Parent Common Shares to such holder
     (in each case less any  amounts  withheld  on  account of tax  pursuant  to
     Section 13.3), without interest,  against presentation and surrender of the
     certificates  for the  Exchangeable  Shares held by them 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
     Exchangeable  Shares  shall  thereafter  be  considered  and deemed for all
     purposes to be holders of the Parent Common Shares delivered to them or the
     custodian on their behalf.

                            PURCHASE FOR CANCELLATION

8.1  Subject to  applicable  law and  notwithstanding  Section 8.2  hereof,  the
     Corporation may at any time and from time to time purchase for cancellation
     all or any part of the  Exchangeable  Shares by private  agreement with any
     holder of Exchangeable Shares.

8.2  Subject to applicable law, 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 8.2,  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  part  only  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.

                                   ARTICLE 9
                        VOTING RIGHTS AND EXCHANGE RIGHTS

9.1  Except as required by  applicable  law and by Article 10,  Section 11.1 and
     Section 12.2 hereof,  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 any such meeting.  Without
     limiting the generality of the foregoing, to the extent permitted by

<PAGE>

                                      -17-

     applicable law, the holders of the Exchangeable Shares shall not have class
     votes in the  circumstances  contemplated  by  Section  61 of the BCA as in
     force on the Effective Date.

9.2  Upon and  subject  to the terms and  conditions  contained  in these  share
     provisions:

     (a)  a holder of  Exchangeable  Shares shall have the right (the  "Exchange
          Put Right")  upon the  occurrence  of an Exchange Put Event to require
          Parent to purchase all or any part of the  Exchangeable  Shares of the
          holder; and

     (b)  upon the  exercise by the holder of the  Exchange Put Right the holder
          shall be required to sell to Parent,  and Parent  shall be required to
          purchase  from the  holder,  that  number  of  Exchangeable  Shares in
          respect of which the Exchange Put Right is exercised, in consideration
          of the  payment by Parent of an amount per share  equal to the sum of:
          (i) the  Current  Market  Price of a Parent  Common  Share on the last
          Business Day prior to the Exchange Put Date (the "Put Amount"),  which
          shall be  satisfied  in full by Parent  delivering  to such holder one
          Parent  Common  Share,  and (ii) an amount  equal to all  declared and
          unpaid dividends on each such  Exchangeable  Share held by such holder
          on any dividend  record date which  occurred prior to the Exchange Put
          Date (collectively, the "Put Consideration").

9.3  The Exchange Put Right may be exercised  upon the occurrence of an Exchange
     Put Event by notice in writing  given by the holder to and  received by the
     Trustee (the date of such receipt, the "Exchange Put Date") and accompanied
     by  presentation  and  surrender  of  the  certificates  representing  such
     Exchangeable  Shares,  and, in the event that at the time of  purchase  the
     Exchangeable Shares are not listed on a recognized Canadian stock exchange,
     a completed  Section  116  certificate  under the Income Tax Act  (Canada),
     together with such documents and instruments as may be required to effect a
     transfer  of  Exchangeable  Shares  under the BCA and the  Articles  of the
     Corporation  and such  additional  documents and instruments as the Trustee
     may reasonably  require,  at the principal  transfer  offices in Vancouver,
     British  Columbia of the  Trustee,  or such other  office or offices of the
     Trustee or of the other persons  designated by the Trustee for that purpose
     as may from time to time be  maintained  by the Trustee  for that  purpose.
     Such  notice  may be (i)  in  the  forms  of  the  panel,  if  any,  on the
     certificates  representing  Exchangeable  Shares,  (ii) in such  other form
     satisfactory  to the  Trustee  (or such  other  persons  aforesaid),  shall
     stipulate the number of  Exchangeable  Shares in respect of which the right
     is  exercised  (which may not exceed  the number of shares  represented  by
     certificates  surrendered to the Trustee),  shall be irrevocable unless the
     exchange is not completed in accordance  herewith and shall  constitute the
     holder's authorization to the Trustee (and such other persons aforesaid) to
     effect the exchange on behalf of the holder.

9.4  The completion of the sale and purchase referred to in Section 9.3 shall be
     required to occur,  and Parent shall be required to take all actions on its
     part necessary to permit it to occur,  not later than the close of business
     on the third Business Day following the Exchange Put Date.

<PAGE>

                                      -18-

9.5  The surrender by the holder of Exchangeable  Shares under Section 9.4 shall
     constitute  the  representation,  warranty  and covenant of the holder that
     Exchangeable Shares so purchased are sold free and clear of any lien, claim
     or encumbrance.

9.6  If a part only of the  Exchangeable  Shares  represented by any certificate
     are to be sold and  purchased  pursuant to the exercise of the Exchange Put
     Right, a new certificate for the balance of such Exchangeable  Shares shall
     be issued to the holder at the expense of the Corporation.

9.7  Upon receipt by the Trustee of the notice, certificates and other documents
     or instruments required by Section 9.8, the Trustee shall pay, on behalf of
     Parent and subject to receipt by the Trustee from Parent of the  applicable
     Put Consideration,  to the relevant holder,  the Put Amount,  together with
     payment of all declared and unpaid  dividends  on each  Exchangeable  Share
     held by such holder on any dividend record date which occurred prior to the
     Exchange Put Date, less any amounts  withheld on account of tax pursuant to
     Section  13.3,  by  delivering  to each holder the Parent  Common Shares to
     which such holder is entitled  and by  delivering  to such  holder,  at the
     address of such holder  recorded in the  register  of  shareholders  of the
     Corporation for the  Exchangeable  Shares or by holding for pick-up by such
     holder at the registered  office of the Corporation or at any office of the
     Transfer  Agent  as  may  be  specified  by  the  Corporation  certificates
     representing  Parent  Common  Shares  (which shares shall be fully paid and
     non-assessable and shall be free of any lien, claim or encumbrance) and, if
     applicable,  a cheque payable at par in payment of any such  dividends,  in
     each case, less any amounts  withheld on account of tax pursuant to Section
     13.3.

9.8  On and after the close of business on the Exchange Put Date,  the holder of
     the  Exchangeable  Shares in  respect  of which the  Exchange  Put Right is
     exercised shall cease to be a holder of such Exchangeable  Shares and shall
     not be  entitled  to  exercise  any of the  rights of a holder  in  respect
     thereof,  other than the right to  receive  its  proportionate  part of the
     total Put  Amount  and any such  dividends  for such  Exchangeable  Shares,
     unless  such  payment  shall not be made,  in which case the rights of such
     holder shall  remain  unaffected  until such payment has been made.  On and
     after  the close of  business  on the  Exchange  Put  Date,  provided  that
     presentation  and surrender of  certificates  and payments of the total Put
     Amount and any such dividends for such Exchangeable Shares has been made in
     accordance with the foregoing  provisions,  the holder of the  Exchangeable
     Shares so purchased by Parent shall thereafter be considered and deemed for
     all purposes to be a holder of the Parent Common Share  delivered to it and
     entitled  to all  dividends  and other  distributions  with  respect to the
     Parent  Common  Shares to which such holder is entitled  with a record date
     after the  Exchange Put Date and before the date of transfer of such Parent
     Common  Shares to such  holder (in each case less any  amounts  withheld on
     account of tax pursuant to Section 13.3), without interest.

                             AMENDMENT AND APPROVAL

10.1 The  rights,  privileges,  restrictions  and  conditions  attaching  to the
     Exchangeable  Shares may be added to,  changed or removed but only with the

     change or remove any right,  privilege,  restriction or condition attaching
     to the  Exchangeable  Shares or any other matter  requiring the approval or
     consent of the holders of the  Exchangeable  Shares shall be deemed to have

     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 to such time and place as may be designated by the Chairman
     of such  meeting.  At such  adjourned  meeting the holders of  Exchangeable
     Shares  present or  represented  by proxy thereat may transact the business
     for which the meeting was originally called and a resolution passed thereat
     by the  affirmative  vote of not less than  two-thirds of the votes cast on

           RECIPROCAL CHANGES, ETC. IN RESPECT OF PARENT COMMON SHARES

11.1 Each  holder  of  an  Exchangeable  Share  acknowledges  that  the  Support
     Agreement  provides,  in part, that so long as any Exchangeable  Shares not
     owned by Parent or its Affiliates are outstanding,  Parent will not without
     the prior approval of the Corporation and the prior approval of the holders
     of the  Exchangeable  Shares given in accordance with Section 10.2 of these
     share provisions:

     (a)  issue or distribute  Parent Common Shares (or securities  exchangeable
          for or  convertible  into or carrying  rights to acquire Parent Common
          Shares)  to  the  holders  of  all or  substantially  all of the  then
          outstanding  Parent  Common  Shares by way of stock  dividend or other
          distribution,  other  than  an  issue  of  Parent  Common  Shares  (or
          securities  exchangeable for or convertible into or carrying rights to
          acquire  Parent Common  Shares) to holders of Parent Common Shares (i)
          who exercise an option to receive  dividends in Parent  Common  Shares
          (or securities exchangeable for or convertible into or carrying rights
          to acquire Parent Common Shares) in lieu of receiving cash  dividends,
          or (ii) pursuant to any dividend reinvestment plan;

     (b)  issue or distribute rights,  options or warrants to the holders of all
          or  substantially  all of the then  outstanding  Parent  Common Shares
          entitling  them to subscribe  for or to purchase  Parent Common Shares
          (or securities exchangeable for or convertible into or carrying rights
          to acquire Parent Common Shares); or

     (c)  issue or distribute to the holders of all or substantially  all of the
          then outstanding Parent Common Shares:

          (i)  shares or  securities  of Parent of any class  other than  Parent
               Common Shares (other than shares or securities  convertible  into
               or  exchangeable  for or carrying rights to acquire Parent Common
               Shares);

          (ii) rights,  options or  warrants  other than  those  referred  to in
               Section 11.1(b)above;

          (iii) evidences of indebtedness of Parent; or

          (iv) assets of Parent,

     unless  the  economic  equivalent  on a per  share  basis  of such  rights,
     options, warrants,  securities,  shares, evidences of indebtedness or other
     assets  is  issued  or  distributed   simultaneously   to  holders  of  the
     Exchangeable  Shares;  provided  that,  for  greater  certainty,  the above
     restrictions  shall not apply to any  securities  issued or  distributed by
     Parent  in  order  to  give  effect  to  and  consummate  the  transactions
     contemplated  by, and in accordance  with, the Combination  Agreement.  The
     Support Agreement further provides,  in part, that the aforesaid provisions
     of the Support  Agreement  shall not be changed without the approval of the
     holders of the Exchangeable Shares given in accordance with Section 10.2 of
     these share provisions.

11.2 Each  holder  of  an  Exchangeable  Share  acknowledges  that  the  Support
     Agreement  further  provides,  in  part,  that so long as any  Exchangeable
     Shares not owned by Parent or its Affiliates are  outstanding,  Parent will
     not without the prior approval of the Corporation and the prior approval of
     the holders of the  Exchangeable  Shares given in  accordance  with Section
     10.2 of these share provisions:

     (a)  subdivide,  redivide  or change  the then  outstanding  Parent  Common
          Shares into a greater number of Parent Common Shares;

     (b)  reduce,  combine,  consolidate or change the then  outstanding  Parent
          Common Shares into a lesser number of Parent Common Shares; or

     (c)  reclassify  or otherwise  change the Parent Common Shares or effect an
          amalgamation,  merger,  reorganization or other transaction  affecting
          the Parent Common Shares,

     unless the same or an economically  equivalent change shall  simultaneously
     be made to, or in, the rights of the  holders of the  Exchangeable  Shares,
     provided  that, for greater  certainty,  the above  restrictions  shall not
     apply to any securities issued or distributed by

     Parent  in  order  to  give  effect  to  and  consummate  the  transactions
     contemplated  by, and in accordance  with, the Combination  Agreement.  The
     Support Agreement further provides,  in part, that the aforesaid provisions
     of the Support  Agreement  shall not be changed without the approval of the
     holders of the Exchangeable Shares given in accordance with Section 10.2 of
     these share provisions.

11.3 If Parent,  at any time after the date hereof,  consummates any transaction
     (whether   by  way  of   reconstruction,   reorganization,   consolidation,
     arrangement,  merger,  transfer,  sale, lease or otherwise)  whereby all or
     substantially all of its undertaking,  property and assets would become the
     property of any other Person or, in the case of a merger, of the continuing
     corporation  or other  entity  resulting  therefrom  (such other  person or
     continuing  corporation  (or,  in the  event of a merger,  amalgamation  or
     similar  transaction  pursuant to which holders of shares in the capital of
     Parent are entitled to receive  shares or other  ownership  interest in the
     capital of any  corporation  or other  legal  entity  other than such other
     person or  continuing  corporation,  then such  corporation  or other legal
     entity in which  holders of shares in the capital of Parent are entitled to
     receive  an  interest)  is herein  called  the  "Parent  Successor")  then,
     provided that the Parent  Successor is bound, or has agreed to be bound, by
     the  provisions  of the Voting and  Exchange  Trust  Agreement  and Support
     Agreement  and to  assume  the  obligations  of  Parent  thereunder  to the
     satisfaction of the Board of Directors,  all references in these Provisions
     Articles of  Incorporation  to Parent  Common  Shares shall be deemed to be
     references  to the shares of the Parent  Successor  which has  assumed  the
     obligations  of Parent  and all  references  to  Parent  shall be to Parent
     Successor,  without amendment to these Provisions Articles of Incorporation
     or any further action whatsoever.  For greater certainty,  if a transaction
     described in this Section  11.3 results in holders of  Exchangeable  Shares
     being entitled to exchange their Exchangeable Shares for shares of a Parent
     Successor in a different ratio than that set out in these share provisions,
     then these share  provisions shall be deemed to be amended to refer to such
     different ratio(s).

               ACTIONS BY THE CORPORATION UNDER SUPPORT AGREEMENT

12.1 The Corporation  will take all such actions and do all such things as shall
     be  necessary  or  advisable  to  perform  and  comply  with and to  ensure

     Corporation,  respectively, in accordance with the terms thereof including,
     without  limitation,  taking all such  actions and doing all such things as
     shall be necessary or advisable to enforce to the fullest  extent  possible
     for the direct benefit of the Corporation all rights and benefits in favour
     of the Corporation under or pursuant to such agreement.

12.2 The Corporation shall not propose, agree to or otherwise give effect to any
     amendment to, or waiver or forgiveness of its rights or obligations  under,
     the  Support   Agreement  without  the  approval  of  the  holders  of  the
     Exchangeable  Shares given in  accordance  with Section 10.2 of these share
     provisions other than such amendments, waivers and/or forgiveness as may be
     necessary or advisable for the purposes of:

     (a)  adding to the covenants of the other parties to such agreement for the
          protection  of the  Corporation  or the  holders  of the  Exchangeable
          Shares thereunder;

     (b)  making such provisions or  modifications  not  inconsistent  with such
          agreement as may be necessary or desirable  with respect to matters or
          questions  arising  thereunder which, in the good faith opinion of the
          Board of  Directors,  it may be expedient to make,  provided  that the
          Board  of  Directors  shall  be  of  the  good  faith  opinion,  after
          consultation with counsel, that such provisions and modifications will
          not be prejudicial to the interests of the holders of the Exchangeable
          Shares; or

     (c)  making such changes in or corrections to such agreement  which, on the
          advice of counsel to the Corporation,  are required for the purpose of
          curing or correcting any ambiguity or defect or inconsistent provision
          or clerical  omission or mistake or manifest error contained  therein,
          provided  that the  Board  of  Directors  shall  be of the good  faith
          opinion,  after  consultation  with  counsel,  that  such  changes  or
          corrections will not be prejudicial to the interests of the holders of
          the Exchangeable Shares.

                     LEGEND; CALL RIGHTS; WITHHOLDING RIGHTS

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, the Redemption
     Call Right and the  Parent  Call  Right,  the  Voting  and  Exchange  Trust
     Agreement  (including  the  provisions  with respect to the voting  rights,
     exchange right and automatic exchange rights thereunder) and the Retraction
     Call Right.

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,  the
     Redemption Call Right and the Parent Call Right, in each case, in favour of
     Callco or Parent,  as the case may be,  and in the case of the  Liquidation
     Call Right,  the Retraction Call Right and the Redemption  Call Right,  the
     overriding  nature thereof in connection with the liquidation,  dissolution
     or winding-up of the Corporation or other distribution of the assets of the
     Corporation  among its  shareholders  for the  purpose  of  winding  up its
     affairs or the retraction or redemption of Exchangeable Shares, as the case
     may be, and to be bound thereby in favour of Callco or Parent,  as the case
     may be, as therein provided.

13.3 The Corporation, Callco, Parent and the Transfer Agent 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,  Callco,
     Parent or the  Transfer  Agent is  required  to deduct  and  withhold  with
     respect  to such  payment  under the Income  Tax Act  (Canada),  the United
     States  Internal  Revenue  Code  of  1986  or  any  provision  of  federal,
     provincial,  territorial, state, local or foreign tax law, in each case, as
     amended or  succeeded,  or entitled to  withhold  under  Section 116 of the
     Income Tax Act (Canada) or

<PAGE>

                                      -23

     any corresponding  provision of provincial laws. To the extent that amounts
     are so withheld, such withheld amounts shall be treated for all purposes 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 entitled 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,  Callco,  Parent and the
     Transfer Agent are hereby  authorized to sell or otherwise  dispose of such
     portion of the consideration as is necessary to provide sufficient funds to
     the Corporation,  Callco, Parent or the Transfer Agent, as the case may be,
     to enable it to comply with such  deduction or  withholding  requirement or
     entitlement and the Corporation, Callco, Parent or the Transfer Agent shall
     notify the holder thereof and remit to such holder any unapplied balance of
     the net proceeds of such sale.

          Exchangeable Shares (an "Equivalent Stock Subdivision");

     (b)  advise Exchangeco sufficiently in advance of the declaration by Parent
          of any  dividend  on  Parent  Common  Shares  and take all such  other
          actions as are reasonably necessary,  in co-operation with Exchangeco,
          to  ensure  that the  respective  declaration  date,  record  date and
          payment  date  for an  Equivalent  Dividend  shall  be the same as the
          declaration  date,  record date and payment date for the corresponding
          dividend  on the Parent  Common  Shares;  or, the record  date and the
          effective date for the Equivalent Stock  Subdivision shall be the same
          as the  record  date  and  payment  date for the  corresponding  stock
          dividend on the Parent Common Shares;

     (c)  ensure that the record date for any dividend declared on Parent Common
          Shares is not less than 10 Business Days after the declaration date of
          such dividend;

     (d)  take  all  such  actions  and do all  such  things  as are  reasonably
          necessary or desirable to enable and permit Exchangeco,  in accordance

          or 7, as the case may be, of the Share Provisions;

     (e)  take  all  such  actions  and do all  such  things  as are  reasonably
          necessary or desirable to (i) perform its obligations upon exercise of

          Right,  including  without  limitation  all such  actions and all such

          the Liquidation Call Right, the Retraction Call Right, the Parent Call
          Right or the Redemption Call Right, as the case may be;

          Exchangeco  nor take any  action  or omit to take any  action  that is

2.7) to be issued and delivered hereunder require  registration or qualification
with or approval of or the filing of any document,  including any  prospectus or
similar  document,  or the taking of any proceeding with or the obtaining of any
order, ruling or consent from any governmental or regulatory authority under any
United States or Canadian  federal,  provincial or state securities or other law
or regulation or

<PAGE>

                                      -5-

pursuant to the rules and  regulations  of any  securities  or other  regulatory
authority  or the  fulfillment  of any other  United  States or  Canadian  legal
requirement  before  such  shares (or such other  shares or  securities)  may be
issued by Parent and  delivered  by Parent at the  direction  of  Exchangeco  or
Callco, if applicable,  to the holder of surrendered  Exchangeable  Shares or in
order that such shares (or such other shares or securities) may be freely traded
thereafter  (other than any  restrictions of general  application on transfer by
reason of a holder being a "control person" for purposes of Canadian  provincial
securities law or an "affiliate" of Parent for purposes of United States federal
or state securities law), Parent will in good faith  expeditiously take all such
actions and do all such things as are reasonably necessary or desirable to cause
such Parent Common Shares (or such other shares or  securities) to be and remain
duly  registered,  qualified or approved under United States or Canadian law, as
the case may be. Parent will in good faith  expeditiously  take all such actions
and do all such things as are  reasonably  necessary  or  desirable to cause all
Parent  Common  Shares  (or such other  shares or  securities)  to be  delivered
hereunder to be listed,  quoted or posted for trading on all stock exchanges and
quotation  systems  on which  outstanding  Parent  Common  Shares (or such other
shares or  securities)  have been  listed by Parent  and  remain  listed and are
quoted or posted for trading at such time.

2.7  Economic Equivalence

     So long as any  Exchangeable  Shares not owned by Parent or its  Affiliates
are outstanding:

     (a)  Parent will not without  prior  approval of  Exchangeco  and the prior
          approval of the holders of the Exchangeable Shares given in accordance
          with Section 10.2 of the Share Provisions:

          (i)  issue  or  distribute   Parent   Common  Shares  (or   securities
               exchangeable  for or  convertible  into  or  carrying  rights  to
               acquire   Parent  Common   Shares)  to  the  holders  of  all  or
               substantially all of the then outstanding Parent Common Shares by
               way of stock dividend or other distribution,  other than an issue
               of  Parent  Common  Shares  (or  securities  exchangeable  for or
               convertible  into or  carrying  rights to acquire  Parent  Common
               Shares) to holders of Parent  Common  Shares (i) who  exercise an
               option  to  receive   dividends  in  Parent   Common  Shares  (or
               securities  exchangeable  for or  convertible  into  or  carrying
               rights to acquire Parent Common Shares) in lieu of receiving cash
               dividends, or (ii) pursuant to any dividend reinvestment plan; or

          (ii) issue or distribute rights, options or warrants to the holders of
               all or substantially  all of the then  outstanding  Parent Common
               Shares  entitling  them to  subscribe  for or to purchase  Parent
               Common Shares (or securities exchangeable for or convertible into
               or carrying rights to acquire Parent Common Shares); or

          (iii)issue or  distribute to the holders of all or  substantially  all
               of the then  outstanding  Parent  Common  Shares  (A)  shares  or
               securities of Parent of any class other than Parent Common Shares
               (other than shares or securities convertible into or exchangeable
               for or carrying  rights to acquire  Parent  Common  Shares),  (B)
               rights, options or warrants other than those

<PAGE>

                                      -6-

               referred to in Section 2.7(a)(ii),  (C) evidences of indebtedness
               of Parent or (D) assets of Parent;

          unless in each case the  economic  equivalent  on a per share basis of
          such  rights,  options,  warrants,  securities,  shares,  evidences of
          indebtedness  or other assets is issued or distributed  simultaneously
          to holders of the  Exchangeable  Shares;  provided  that,  for greater
          certainty,  the above  restrictions  shall not apply to any  shares or
          securities  issued or distributed by Parent in order to give effect to
          and to consummate the transactions  contemplated by, and in accordance
          with, the Combination Agreement.

     (b)  Parent will not without the prior approval of Exchangeco and the prior
          approval of the holders of the Exchangeable Shares given in accordance
          with Section 10.2 of the Share Provisions:

          (i)  subdivide,  redivide or change the then outstanding Parent Common
               Shares into a greater number of Parent Common Shares; or

          (ii) reduce,  combine,  consolidate  or  change  the then  outstanding
               Parent  Common  Shares  into a lesser  number  of  Parent  Common
               Shares; or

          (iii)reclassify or otherwise  change Parent Common Shares or effect an
               amalgamation,   merger,   reorganization   or  other  transaction
               affecting Parent Common Shares;

          unless  the  same  or  an   economically   equivalent   change   shall
          simultaneously  be made to, or in the  rights of the  holders  of, the
          Exchangeable Shares;  provided that, for greater certainty,  the above
          restrictions  shall not apply to any shares or other securities issued
          or  distributed by Parent in order to give effect to and to consummate
          the  transactions   contemplated  by,  and  in  accordance  with,  the
          Combination Agreement.

     (c)  Parent will  ensure that the record date for any event  referred to in
          Section 2.7(a) or Section 2.7(b),  or (if no record date is applicable
          for such event) the  effective  date for any such  event,  is not less
          than five Business Days after the date on which such event is declared
          or announced by Parent (with  contemporaneous  notification thereof by
          Parent to Exchangeco).

     (d)  The Board of Directors of Exchangeco  shall  determine,  in good faith
          and in its sole discretion,  economic  equivalence for the purposes of
          any event  referred to in Section 2.7(a) or Section  2.7(b),  and each
          such  determination  shall be  conclusive  and  binding on Parent.  In
          making each such determination,  the following factors shall,  without
          excluding  other  factors  determined  by the  Board of  Directors  of
          Exchangeco to be relevant,  be considered by the Board of Directors of
          Exchangeco:

          (i)  in the case of any stock dividend or other  distribution  payable
               in Parent  Common  Shares,  the number of such shares issued as a
               result of such

<PAGE>

                                      -7-

               dividend or  distribution  in  proportion to the number of Parent
               Common Shares previously outstanding;

          (ii) in the  case  of the  issuance  or  distribution  of any  rights,
               options or warrants to subscribe  for or purchase  Parent  Common
               Shares (or securities  exchangeable  for or  convertible  into or
               carrying   rights  to  acquire   Parent   Common   Shares),   the
               relationship  between  the  exercise  price of each  such  right,
               option or warrant and the Current Market Price of a Parent Common
               Share;

          (iii)in the case of the issuance or  distribution of any other form of
               property  (including  without limitation any shares or securities
               of Parent of any class  other  than  Parent  Common  Shares,  any
               rights,  options or  warrants  other than  those  referred  to in
               Section 2.7(d)(i), any evidences of indebtedness of Parent or any
               assets of Parent), the relationship between the fair market value
               (as  determined  by the Board of Directors of  Exchangeco  in the
               manner  above  contemplated)  of such  property  to be  issued or
               distributed with respect to each outstanding  Parent Common Share
               and the Current Market Price of a Parent Common Share;

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

          (v)  in all such  cases,  the  general  taxation  consequences  of the
               relevant event to beneficial owners of Exchangeable Shares to the
               extent  that  such  consequences  may  differ  from the  taxation
               consequences  to such  beneficial  owners  determined  as if they
               owned Parent  Common  Shares at the relevant  time as a result of
               differing tax  treatment  under the 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 beneficial  owners of  Exchangeable
               Shares).

     (e)  Exchangeco  agrees that, to the extent required,  upon due notice from
          Parent,  Exchangeco  will use its best  efforts to take or cause to be
          taken such steps as may be necessary for the purposes of ensuring that
          appropriate  dividends  are  paid or other  distributions  are made by
          Exchangeco,  or  subdivisions,  redivisions or changes are made to the
          Exchangeable  Shares,  in order to  implement  the  required  economic
          equivalence  with respect to the Parent Common Shares and Exchangeable
          Shares as provided for in this Section 2.7.

                                      -8-

2.8  Tender Offers

     So long as any  Exchangeable  Shares not owned by Parent or its  Affiliates
are outstanding,  in the event that a tender offer, share exchange offer, issuer
bid,  take-over bid or similar  transaction with respect to Parent Common Shares
(an "Offer") is proposed by Parent or is proposed to Parent or its  shareholders
and is recommended by the Board of Directors of Parent, or is otherwise effected
or to be effected  with the consent or  approval  of the Board of  Directors  of
Parent, and the Exchangeable  Shares are not redeemed by Exchangeco or purchased
by Callco pursuant to the Redemption Call Right,  Parent will use its reasonable
best efforts expeditiously and in good faith to take all such actions and do all
such  things as are  necessary  or  desirable  to enable and  permit  holders of
Exchangeable  Shares (other than Parent and its  Affiliates)  to  participate in
such Offer to the same  extent and on an  economically  equivalent  basis as the
holders of Parent Common Shares,  without  discrimination.  Without limiting the
generality  of  the   foregoing,   Parent  will  use  its   reasonable   efforts
expeditiously  and in good faith to ensure that holders of  Exchangeable  Shares
may   participate   in  each  such  Offer  without  being  required  to  retract
Exchangeable  Shares as against  Exchangeco (or, if so required,  to ensure that
any such  retraction,  shall be effective  only upon,  and shall be  conditional
upon,  the closing of such Offer and only to the extent  necessary  to tender or
deposit to the Offer).  Nothing  herein shall affect the rights of Exchangeco to
redeem  (or  Callco  to  purchase   pursuant  to  the  Redemption   Call  Right)
Exchangeable   Shares,  as  applicable,   in  the  event  of  a  Parent  Control
Transaction.

2.9  Ownership of Outstanding Shares

     Parent covenants and agrees in favour of Exchangeco that, without the prior
approval of Exchangeco and the prior approval of the holders of the Exchangeable
Shares given in accordance with Section 10.2 of the Share Provisions, as long as
any outstanding Exchangeable Shares are owned by any Person other than Parent or
any of its  Affiliates,  Parent  will  be and  remain  the  direct  or  indirect
beneficial  owner of all issued and outstanding  voting shares in the capital of
Exchangeco and Callco.

2.10 Parent and Affiliates Not to Vote Exchangeable Shares

     Parent  covenants and agrees that it will appoint and cause to be appointed
proxyholders  with  respect  to all  Exchangeable  Shares  held  by it  and  its
Affiliates  for the sole  purpose  of  attending  each  meeting  of  holders  of
Exchangeable  Shares in order to be  counted as part of the quorum for each such
meeting.  Parent  further  covenants and agrees that it will not, and will cause
its  Affiliates  not to,  exercise any voting rights which may be exercisable by
holders  of  Exchangeable  Shares  from  time  to  time  pursuant  to the  Share
Provisions  or pursuant to the  provisions of the BCA (or any successor or other
corporate  statute  by which  Exchangeco  may in the  future be  governed)  with
respect to any Exchangeable Shares held by it or by its Affiliates in respect of
any matter considered at any meeting of holders of Exchangeable Shares.

2.11 Ordinary Market Purchases

     For greater  certainty,  nothing  contained  in this  agreement,  including
without  limitation the  obligations  of Parent  contained in Section 2.8, shall
limit  the  ability  of  Parent  (or any of its  Affiliates  including,  without
limitation,  Callco or  Exchangeco)  to make a "Rule 10b-18  Purchase" of Parent
Common Shares pursuant to Rule 10b-18 of the U.S. Securities and

<PAGE>

                                      -9-

Exchange Act of 1934, as amended,  or any successor  provisions  thereof,  or to
make  ordinary  market  purchases  of Parent  Common  Shares  and  otherwise  in
accordance with applicable laws and regulatory or stock exchange requirements.

2.12 Stock Exchange Listing

     Parent  covenants and agrees in favour of  Exchangeco  that, as long as any
outstanding Exchangeable Shares are owned by any Person other than Parent or any
of its  Affiliates,  Parent will use its  reasonable  best efforts to maintain a
listing for such  Exchangeable  Shares on a Canadian  stock  exchange which is a
prescribed stock exchange within the meaning of the Income Tax Act (Canada).

                                   ARTICLE 3
                               PARENT SUCCESSORS

3.1  Certain Requirements in Respect of Combination, etc.

     As long as any  outstanding  Exchangeable  Shares  are owned by any  Person
other than Parent or any of its  Affiliates,  Parent  shall not  consummate  any
transaction  (whether by way of reconstruction,  reorganization,  consolidation,
arrangement,  merger,  transfer,  sale,  lease  or  otherwise)  whereby  all  or
substantially  all of its  undertaking,  property  and assets  would  become the
property  of any other  Person  or, in the case of a merger,  of the  continuing
corporation or other entity resulting therefrom unless, but may do so if:

     (a)  such other Person or  continuing  corporation  or, in the event of any
          merger,  amalgamation or similar transaction pursuant to which holders
          of shares in Parent are  entitled to receive  shares in the capital of
          any  corporation or other legal entity other than such other Person or
          continuing corporation, then such corporation or legal entity (in each
          case, the "Parent  Successor") by operation of law,  becomes,  without
          more,  bound by the terms and  provisions of this agreement or, if not
          so  bound,   executes,   prior  to  or   contemporaneously   with  the
          consummation of such transaction,  an agreement supplemental hereto or
          otherwise  agrees to become bound by the terms and  provisions of this
          agreement,  in either case  together with such other  instruments  (if
          any)  as  are  reasonably  necessary  or  advisable  to  evidence  the
          assumption by the Parent Successor of liability for all moneys payable
          and  property  deliverable  hereunder  and the covenant of such Parent
          Successor to pay and deliver or cause to be delivered the same and its
          agreement to observe and perform all the covenants and  obligations of
          Parent under this agreement; and

     (b)  such   transaction   shall  be  upon  such  terms  and  conditions  as
          substantially  to preserve and not to impair in any  material  respect
          any of the rights, duties, powers and authorities of the other parties
          hereunder or the holders of the Exchangeable Shares.

3.2  Vesting of Powers in Successor

     Whenever  the  conditions  of  Section  3.1 have  been  duly  observed  and
performed,  the parties,  if required by Section 3.1,  shall execute and deliver
the supplemental agreement

<PAGE>

                                      -10-

provided for in Section 3.1, and  thereupon the Parent  Successor  shall possess
and from  time to time may  exercise  each and  every  right and power of Parent
under  this  agreement  in the  name  of  Parent  or  otherwise  and  any act or
proceeding by any provision of this  agreement  required to be done or performed
by the Board of  Directors  of Parent or any  officers of Parent may be done and
performed with like force and effect by the directors or officers of such Parent
Successor.

3.3  Wholly-Owned Subsidiaries

     Nothing herein shall be construed as preventing the  amalgamation or merger
of any wholly-owned  direct or indirect subsidiary of Parent with or into Parent
or the  winding-up,  liquidation or dissolution  of any  wholly-owned  direct or
indirect  subsidiary  of Parent  (if all of the  assets of such  subsidiary  are
transferred to Parent or another  wholly-owned  direct or indirect subsidiary of
Parent) or any other  distribution of the assets of any  wholly-owned  direct or
indirect  subsidiary of Parent among the shareholders of such subsidiary for the
purpose of winding  up its  affairs,  and any such  transactions  are  expressly
permitted by this Article 3.

                                   ARTICLE 4
                                    GENERAL

4.1  Term

     This agreement shall come into force and be effective as of the date hereof
and shall  terminate  and be of no  further  force and effect at such time as no
Exchangeable  Shares (or securities or rights  convertible  into or exchangeable
for or carrying  rights to acquire  Exchangeable  Shares) are held by any Person
other than Parent and any of its Affiliates.

4.2  Changes in Capital of Parent and Exchangeco

     At all times after the  occurrence  of any event  contemplated  pursuant to
Section 2.7 and Section 2.8, or  otherwise,  as a result of which either  Parent
Common Shares or the  Exchangeable  Shares or both are in any way changed,  this
agreement  shall forthwith be amended and modified as necessary in order that it
shall apply with full force and effect,  mutatis mutandis, to all new securities
into  which  Parent  Common  Shares  or the  Exchangeable  Shares or both are so
changed and the parties hereto shall execute and deliver an agreement in writing
giving effect to and evidencing such necessary amendments and modifications.

4.3  Severability

     If any term or other  provision of this  agreement  is invalid,  illegal or
incapable  of being  enforced  by any rule or law, or public  policy,  all other
conditions and provisions of this agreement  shall  nevertheless  remain in full
force and effect so long as the economic or legal substance of the  transactions
contemplated  hereby is not  affected  in any manner  materially  adverse to any
party.  Upon such  determination  that any term or other  provision  is invalid,
illegal or incapable of being  enforced,  the parties hereto shall  negotiate in
good faith to modify this  agreement so as to effect the original  intent of the
parties as  closely  as  possible  in an  acceptable  manner to the end that the
transactions contemplated hereby are fulfilled to the fullest extent possible.

          Exchangeco and Parent and approved by the holders of the  Exchangeable
          Shares in accordance with Section 10.2 of the Share Provisions.

     (2)  No amendment or  modification  or waiver of any of the  provisions  of

4.5  Ministerial Amendments

     Notwithstanding  the  provisions  of  Section  4.4,  the  parties  to  this
agreement may in writing at any time and from time to time, without the approval
of the holders of the  Exchangeable  Shares,  amend or modify this agreement for
the purposes of:

     (a)  adding to the covenants of any or all parties  provided that the Board
          of  Directors  of each of  Exchangeco  and Parent shall be of the good

          rights or interests of the holders of the Exchangeable Shares;

     (b)  making such amendments or  modifications  not  inconsistent  with this
          agreement as may be necessary or desirable  with respect to matters or
          questions  which,  in the good faith opinion of the Board of Directors
          of each  of  Exchangeco  and  Parent,  it may be  expedient  to  make,
          provided that each such Board of Directors  shall be of the good faith
          opinion that such amendments or modifications  will not be prejudicial
          to the rights or interests of the holders of the Exchangeable  Shares;
          or

     (c)  making such changes or corrections  which, on the advice of counsel to
          Exchangeco  and  Parent,  are  required  for the  purpose of curing or
          correcting  any  ambiguity  or defect  or  inconsistent  provision  or
          clerical  omission or mistake or  manifest  error,  provided  that the
          Boards of Directors of each of  Exchangeco  and Parent shall be of the
          good  faith  opinion  that such  changes  or  corrections  will not be
          prejudicial  to  the  rights  or  interests  of  the  holders  of  the
          Exchangeable Shares.

4.6  Meeting to Consider Amendments

     Exchangeco,  at the request of Parent,  shall call a meeting or meetings of
the  holders of the  Exchangeable  Shares for the  purpose  of  considering  any

law for  purposes of  determining  shareholders  entitled to vote at such Parent
Meeting or in respect of such Parent Consent.  Parent will notify the Trustee of
any  decision of the Board of Directors of Parent with respect to the calling of
any Parent Meeting and shall provide all necessary  information and materials to
the Trustee in each case promptly and in any event in sufficient  time to enable
the Trustee to perform its obligations contemplated by this 4.3.

4.4  Copies of Shareholder Information

     Parent will deliver to the Trustee copies of all proxy materials (including
notices of Parent Meetings but excluding  proxies to vote Parent Common Shares),
information statements,  reports (including without limitation,  all interim and
annual  financial  statements)  and other written  communications  that, in each
case,  are to be  distributed  by Parent  from time to time to holders of Parent
Common Shares in sufficient  quantities  and in sufficient  time so as to enable
the Trustee to send those materials to each Beneficiary at the same time as such
materials  are first sent to holders of Parent Common  Shares.  The Trustee will
mail or otherwise send to each Beneficiary,  at the expense of Parent, copies of
all such materials (and all materials specifically directed to the Beneficiaries
or to the Trustee for the benefit of the  Beneficiaries  by Parent)  received by
the Trustee from Parent  contemporaneously with the sending of such materials to
holders of Parent  Common  Shares.  The  Trustee  will also make  available  for
inspection by any  Beneficiary at the Trustee's  principal  office in Vancouver,
British Columbia all proxy materials,  information statements, reports and other
written communications that are:

     (a)  received by the Trustee as the registered holder of the Special Voting
          Share and made available by Parent  generally to the holders of Parent
          Common Shares; or

     (b)  specifically  directed to the  Beneficiaries or to the Trustee for the
          benefit of the Beneficiaries by Parent.

4.5  Other Materials

     As soon as reasonably  practicable  after receipt by Parent or shareholders
of Parent (if such receipt is known by Parent) of any material  sent or given by
or on behalf of a third  party to holders  of Parent  Common  Shares  generally,
including without limitation, dissident proxy and

<PAGE>

                                      -9-

information  circulars (and related  information and material) and take-over bid
and securities  exchange  take-over bid circulars (and related  information  and
material),  provided such material has not been sent to the  Beneficiaries by or
on behalf of such third party, Parent shall use its reasonable efforts to obtain
and deliver to the Trustee  copies  thereof in  sufficient  quantities  so as to
enable the Trustee to forward such  material  (unless the same has been provided
directly to  Beneficiaries  by such third party) to each  Beneficiary as soon as
possible  thereafter.  As soon as reasonably  practicable after receipt thereof,
the Trustee will mail or otherwise send to each  Beneficiary,  at the expense of
Parent,  copies of all such materials  received by the Trustee from Parent.  The
Trustee will also make available for inspection during regular business hours by
any Beneficiary at the Trustee's principal office in Vancouver, British Columbia
copies of all such materials.

4.6  List of Persons Entitled to Vote

     Exchangeco  shall,  (a) prior to each  annual,  general and special  Parent
Meeting or the seeking of any Parent Consent and (b) forthwith upon each request
made at any time by the  Trustee in  writing,  prepare or cause to be prepared a
list (a "List") of the names and  addresses  of the  Beneficiaries  arranged  in
alphabetical order and showing the number of Exchangeable  Shares held of record
by each such  Beneficiary,  in each case at the  close of  business  on the date
specified by the Trustee in such  request or, in the case of a List  prepared in
connection with a Parent Meeting or a Parent  Consent,  at the close of business
on the record  date  established  by Parent or pursuant  to  applicable  law for
determining the holders of Parent Common Shares entitled to receive notice of or
to vote at such Parent Meeting or to give consent in connection with such Parent
Consent. Each such List shall be delivered to the Trustee promptly after receipt
by  Exchangeco of such request or the record date for such meeting or seeking of
consent,  as the case may be,  and in any  event  within  sufficient  time as to
permit the  Trustee to perform  its  obligations  under this  Agreement.  Parent
agrees to give Exchangeco  notice (with a copy to the Trustee) of the calling of
any Parent  Meeting or the  seeking of any  Parent  Consent,  together  with the
record  dates  therefor,  sufficiently  prior to the date of the calling of such
meeting or seeking of such  consent so as to enable  Exchangeco  to perform  its
obligations under this Section 4.6.

4.7  Entitlement to Direct Votes

     Subject to Sections 4.8 and 4.11, any Beneficiary  named in a List prepared
in connection  with any Parent Meeting or Parent Consent will be entitled (a) to
instruct the Trustee in the manner  described in Section 4.3 with respect to the
exercise of the Beneficiary  Votes to which such  Beneficiary is entitled or (b)
to attend  such  meeting  and  personally  exercise  thereat  (or to  personally
exercise with respect to any Parent consent),  as the proxy of the Trustee,  the
Beneficiary Votes to which such Beneficiary is entitled.

4.8  Voting by Trustee and Attendance of Trustee Representative at Meeting

     In  connection  with each Parent  Meeting and Parent  Consent,  the Trustee
shall  exercise,   either  in  person  or  by  proxy,  in  accordance  with  the
instructions   received  from  a  Beneficiary   pursuant  to  Section  4.3,  the
Beneficiary  Votes as to which such  Beneficiary  is entitled to direct the vote
(or  any  lesser  number  thereof  as  may be set  forth  in the  instructions);
provided,  however,  that such written  instructions are received by the Trustee
from the Beneficiary prior to

<PAGE>

                                      -10-

the time and date fixed by the Trustee for  receipt of such  instruction  in the
notice given by the Trustee to the Beneficiary pursuant to Section 4.3.

     The Trustee shall cause a representative who is empowered by it to sign and
deliver,  on behalf of the  Trustee,  proxies  for Voting  Rights to attend each
Parent  Meeting.   Upon  submission  by  a  Beneficiary  (or  its  designee)  of
identification  satisfactory  to  the  Trustee's  representative,   and  at  the
Beneficiary's  request,  such  representative  shall  sign and  deliver  to such
Beneficiary  (or its designee) a proxy to exercise  personally  the  Beneficiary
Votes as to which such Beneficiary is otherwise entitled hereunder to direct the
vote,  if such  Beneficiary  either  (i) has not  previously  given the  Trustee
instructions  pursuant to Section 4.3 in respect of such meeting or (ii) submits
to such representative written revocation of any such previous instructions.  At
such meeting,  the Beneficiary  exercising such Beneficiary Votes shall have the
same  rights as the  Trustee to speak at the  meeting  in favour of any  matter,
question,  proposal or  proposition,  to vote by way of ballot at the meeting in
respect of any matter,  question,  proposal or proposition,  and to vote at such
meeting  by way of a show  of  hands  in  respect  of any  matter,  question  or
proposition.

4.9  Distribution of Written Materials

     Any written materials distributed by the Trustee pursuant to this Agreement
shall be sent by mail (or  otherwise  communicated  in the same manner as Parent
utilizes  in  communications  to holders  of Parent  Common  Shares,  subject to
applicable regulatory requirements and provided such manner of communications is
reasonably available to the Trustee) to each Beneficiary at its address as shown
on the books of Exchangeco.  Exchangeco shall provide or cause to be provided to
the Trustee for purposes of communication,  on a timely basis and without charge
or other expense:

     (a)  a current List; and

     (b)  upon the request of the Trustee,  mailing labels to enable the Trustee
          to carry out its duties under this Agreement.

4.10 Termination of Voting Rights

     Except as otherwise provided herein or in the Share Provisions,  all of the
rights of a Beneficiary  with respect to the  Beneficiary  Votes  exercisable in
respect of the Exchangeable Shares held by such Beneficiary, including the right
to  instruct  the  Trustee  as to  the  voting  of or to  vote  personally  such
Beneficiary  Votes,  shall be deemed to be  surrendered  by the  Beneficiary  to
Parent, Callco or Exchangeco, as the case may be, and such Beneficiary Votes and
the Voting  Rights  represented  thereby  shall cease  immediately  upon (i) the
delivery  by such holder to the Trustee of the  certificates  representing  such
Exchangeable  Shares in connection  with the exercise by the  Beneficiary of the
Exchange  Right,  the  Exchange  Put Right or the  occurrence  of the  automatic
exchange of  Exchangeable  Shares for Parent  Common  Shares,  as  specified  in
Article 5 (unless,  in either case,  Parent shall not have delivered or cause to
be delivered the requisite Parent Common Shares issuable in exchange therefor to
the Trustee pending  delivery to the  Beneficiaries),  or (ii) the retraction or
redemption  of  Exchangeable  Shares  pursuant  to  Article  6 or 7 of the Share
Provisions,  or (iii) the  effective  date of the  liquidation,  dissolution  or
winding-up of Exchangeco pursuant to Article 5 of the Share Provisions,  or (iv)
the purchase of

<PAGE>

                                      -11-

Exchangeable Shares from the holder thereof by Callco or Parent, as the case may
be,  pursuant to the exercise by (i) Callco of the  Retraction  Call Right,  the
Redemption Call Right or the Liquidation Call Right, (ii) the exercise by Parent
of the Parent Call Right, or (iii) the holder of the Exchange Put Right.

4.11 Disclosure of Interest in Exchangeable Shares

     The Trustee or Exchangeco  shall be entitled to require any  Beneficiary or
any  Person who the  Trustee  or  Exchangeco  know or have  reasonable  cause to
believe to hold any interest whatsoever in an Exchangeable Share to confirm that
fact or to give such  details as to whom has an  interest  in such  Exchangeable
Share as would be required (if the  Exchangeable  Shares were a class of "equity
shares"  of  Exchangeco)  under  Section  111 of  the  Securities  Act  (British
Columbia) or under equivalent  legislation,  as each may be amended from time to
time,  or as would be  required  under  the  articles  of  Parent or any laws or
regulations,  or  pursuant  to  the  rules  or  regulations  of  any  regulatory
authority,  of the United States if the  Exchangeable  Shares were Parent Common
Shares.

                                   ARTICLE 5
                  EXCHANGE RIGHT AND AUTOMATIC EXCHANGE RIGHTS

5.1  Grant and Ownership of Exchange Rights

     Parent  hereby  grants to the  Trustee as trustee for and on behalf of, and
for the use and benefit of, the Beneficiaries the right (the "Exchange  Right"),
upon the  occurrence  and during the  continuance  of an  Insolvency  Event,  to
require Parent to purchase from each or any  Beneficiary  all or any part of the
Exchangeable  Shares held by the Beneficiary and the Automatic  Exchange Rights,
all  in  accordance  with  the  provisions  of  this  Agreement.  Parent  hereby
acknowledges  receipt  from the  Trustee  as  trustee  for and on  behalf of the
Beneficiaries of good and valuable  consideration (and the adequacy thereof) for
the grant of the  Exchange  Right,  the  Exchange  Put  Right and the  Automatic
Exchange  Rights  by  Parent to the  Trustee.  During  the term of the Trust and
subject to the terms and conditions of this Agreement, the Trustee shall possess
and be vested with full legal ownership of the Exchange Right,  the Exchange Put
Right and the Automatic Exchange Rights and shall be entitled to exercise all of
the  rights  and powers of an owner with  respect  to the  Exchange  Right,  the
Exchange Put Right and the Automatic Exchange Rights,  provided that the Trustee
shall:

     (a)  hold the Exchange  Right,  the  Exchange  Put Right and the  Automatic
          Exchange  Rights and the legal title thereto as trustee solely for the
          use and benefit of the Beneficiaries in accordance with the provisions
          of this Agreement; and

     (b)  except as specifically authorized by this Agreement,  have no power or
          authority to exercise or otherwise deal in or with the Exchange Right,
          the  Exchange  Put Right or the  Automatic  Exchange  Rights,  and the
          Trustee  shall not exercise any such rights for any purpose other than
          the  purposes  for  which  the  Trust  is  created  pursuant  to  this
          Agreement.

<PAGE>

                                      -12-

     The  obligations  of Parent to issue Parent Common  Shares  pursuant to the
Exchange  Right,  the Exchange Put Right or the  Automatic  Exchange  Rights are
subject to all applicable laws and regulatory and stock exchange requirements.

5.2  Legended Share Certificates

     Exchangeco will cause each certificate representing  Exchangeable Shares to
bear an appropriate legend notifying the Beneficiaries of:

     (a)  their right to instruct  the Trustee  with  respect to the exercise of
          the  Exchange  Right  and the  Exchange  Put Right in  respect  of the
          Exchangeable Shares held by a Beneficiary; and

     (b)  the Automatic Exchange Rights.

5.3  General Exercise of Exchange Right

     The Exchange Right and the Exchange Put Right shall be and remain vested in
and  exercisable  by the Trustee.  Subject to Section  7.15,  the Trustee  shall
exercise  the  Exchange  Right and the  Exchange  Put Right only on the basis of
instructions received pursuant to this Article 5 from Beneficiaries  entitled to
instruct  the  Trustee  as to the  exercise  thereof.  To  the  extent  that  no
instructions  are received from a Beneficiary with respect to the Exchange Right
and the  Exchange  Put  Right,  the  Trustee  shall not  exercise  or permit the
exercise of the Exchange Right and the Exchange Put Right.

5.4  Purchase Price

     The  purchase  price  payable by Parent for each  Exchangeable  Share to be
purchased by Parent under the Exchange  Right or the Exchange Put Right shall be
an amount per share equal to the sum of (i) the Current Market Price of a Parent
Common  Share on the  last  Business  Day  prior  to the day of  closing  of the
purchase and sale of such  Exchangeable  Share under the  Exchange  Right or the
Exchange Put Right,  which shall be satisfied  in full by Parent  delivering  or
causing  to be  delivered  to the  Trustee  on behalf of such  holder one Parent
Common Share,  plus (ii) to the extent not paid by Exchangeco on the  designated
payment  date  therefor,  an  additional  amount equal 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 closing of the
purchase and sale.  In connection  with each  exercise of the Exchange  Right or
Exchange Put Right, Parent shall provide to the Trustee an Officer's Certificate
setting forth the calculation of the purchase price for each Exchangeable Share.
The total  purchase price for each such  Exchangeable  Share so purchased may be
satisfied  only by Parent  delivering or causing to be delivered to the Trustee,
on  behalf of the  relevant  Beneficiary,  one  Parent  Common  Share and on the
applicable payment date a cheque for the balance,  if any, of the purchase price
without  interest,  less any amounts  withheld  pursuant to Section  5.13.  Upon
payment by Parent of such purchase price the relevant Beneficiary shall cease to
have any right to be paid by  Exchangeco  any amount in respect of declared  and
unpaid dividends on each such  Exchangeable  Share and Exchangeco shall cease to
be obligated to pay any amount in respect of such dividends.

5.5  Exercise Instructions

     Subject to the terms and conditions  herein set forth, a Beneficiary  shall
be entitled,  upon the  occurrence  and during the  continuance of an Insolvency
Event,  to instruct the Trustee to exercise  the Exchange  Right or the Exchange
Put Right with respect to all or any part of the Exchangeable  Shares registered
in the name of such  Beneficiary  on the  books  of  Exchangeco.  To  cause  the
exercise of the Exchange  Right or the  Exchange  Put Right by the Trustee,  the
Beneficiary  shall  deliver  to  the  Trustee,  in  person  or by  certified  or
registered  mail, at its principal  office in Vancouver,  British Columbia or at
such other  places in Canada as the Trustee may from time to time  designate  by
written  notice  to  the  Beneficiaries,   the  certificates   representing  the
Exchangeable  Shares which such  Beneficiary  desires  Parent to purchase,  duly
endorsed in blank for  transfer,  and  accompanied  by such other  documents and
instruments as may be required to effect a transfer of Exchangeable Shares under
the BCA and Notice of Articles and articles of  Exchangeco  and such  additional
documents and  instruments as the Trustee,  Parent and Exchangeco may reasonably
require  together  with (a) a duly  completed  form of notice of exercise of the
Exchange  Right or the  Exchange  Put  Right,  contained  on the  reverse  of or
attached  to  the  Exchangeable  Share   certificates,   stating  (i)  that  the
Beneficiary  thereby  instructs the Trustee to exercise the Exchange Right so as
to require Parent to purchase from the  Beneficiary  the number of  Exchangeable
Shares specified therein,  (ii) that such Beneficiary has good title to and owns
all such  Exchangeable  Shares to be  acquired  by Parent  free and clear of any
lien,  claim  or  encumbrance,   (iii)  the  names  in  which  the  certificates
representing  Parent Common Shares  transferable in connection with the exercise
of the Exchange  Right or the Exchange Put Right are to be  registered  and (iv)
the names and addresses of the Persons to whom such new  certificates  should be
delivered and (b) payment (or evidence  satisfactory to the Trustee,  Exchangeco
and Parent of payment) of the taxes (if any) payable as  contemplated by Section
5.8. If only a part of the Exchangeable Shares represented by any certificate or
certificates  delivered  to the Trustee are to be  purchased by Parent under the
Exchange Right, a new certificate  for the balance of such  Exchangeable  Shares
shall be issued to the holder at the expense of Exchangeco.

5.6  Delivery of Parent Common Shares

     Promptly   after  the  receipt  of  the   certificates   representing   the
Exchangeable  Shares which the Beneficiary  desires Parent to purchase under the
Exchange  Right or the  Exchange Put Right,  together  with such  documents  and
instruments  of transfer and a duly  completed form of notice of exercise of the
Exchange  Right or the Exchange Put Right (and payment of taxes,  if any payable
as contemplated by Section 5.8 or evidence thereof),  duly endorsed in blank for
transfer to Parent,  the  Trustee  shall  notify  Parent and  Exchangeco  of its
receipt of the same,  which  notice to Parent and  Exchangeco  shall  constitute
exercise  of the  Exchange  Right or the  Exchange  Put Right by the  Trustee on
behalf of the holder of such  Exchangeable  Shares,  and Parent  shall  promptly
thereafter deliver or cause to be delivered to the Trustee,  for delivery to the
Beneficiary  of such  Exchangeable  Shares  (or to such other  Persons,  if any,
properly designated by such Beneficiary) certificates representing the number of
Parent  Common Shares  issuable in connection  with the exercise of the Exchange
Right,  and on the applicable  payment date cheques payable at par at any branch
of the bankers of Parent for the balance,  if any, of the total  purchase  price
therefor without  interest (but in each case less any amounts withheld  pursuant
to Section 5.13); provided,  however, that no such delivery shall be made unless
and until the

<PAGE>

                                      -14-

Beneficiary   requesting  the  same  shall  have  paid  (or  provided   evidence
satisfactory to the Trustee,  Exchangeco and Parent of the payment of) the taxes
(if any) payable as contemplated  by Section 5.8 of this Agreement.  Immediately
upon the  giving of notice  by the  Trustee  to  Parent  and  Exchangeco  of the
exercise of the  Exchange  Right or the  Exchange  Put Right as provided in this
Section 5.6, the closing of the transaction of purchase and sale contemplated by
the  Exchange  Right  shall be deemed to have  occurred  and the  holder of such
Exchangeable  Shares shall be deemed to have  transferred  to Parent all of such
holder's right,  title and interest in and to such  Exchangeable  Shares and the
related  interest  in the Trust  Estate  free and  clear of any  lien,  claim or
encumbrance and shall cease to be a holder of such Exchangeable 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  purchase
price  therefor,  unless the  requisite  number of Parent  Common  Shares is not
delivered by, or on behalf of,  Parent to the Trustee  within five Business Days
of the date of the giving of such  notice by the  Trustee or the  balance of the
purchase  price,  if any, is not paid by Parent on the  applicable  payment date
therefor,  in which case the rights of the Beneficiary  shall remain  unaffected
until  such  Parent  Common  Shares  are so  delivered,  and the  balance of the
purchase price, if any, has been paid, by Parent. Upon delivery by Parent to the
Trustee of such Parent Common Shares,  and the balance of the purchase price, if
any, the Trustee shall deliver such Parent Common Shares to such Beneficiary (or
to  such  other  Persons,  if any,  properly  designated  by such  Beneficiary).
Concurrently  with  such  Beneficiary  ceasing  to be a holder  of  Exchangeable
Shares,  the  Beneficiary  shall be considered and deemed for all purposes to be
the holder of the Parent Common Shares  delivered to it pursuant to the Exchange
Right or the Exchange Put Right.

5.7  Exercise of Exchange Right Subsequent to Retraction

     In the event that a Beneficiary  has exercised its right under Article 6 of
the  Share  Provisions  to  require  Exchangeco  to  redeem  any  or  all of the
Exchangeable  Shares held by the  Beneficiary  (the  "Retracted  Shares") and is
notified by  Exchangeco  pursuant to Section  6.6 of the Share  Provisions  that
Exchangeco  will  not be  permitted  as a result  of  solvency  requirements  of
applicable  law to redeem all such  Retracted  Shares,  and provided that Callco
shall not have exercised the Retraction Call Right with respect to the Retracted
Shares and that the Beneficiary has not revoked the retraction request delivered
by the Beneficiary to Exchangeco pursuant to Section 6.1 of the Share Provisions
and provided  further that the Trustee has received  written notice of same from
Exchangeco or Callco,  the retraction request will constitute and will be deemed
to constitute notice from the Beneficiary to the Trustee instructing the Trustee
to exercise  the  Exchange  Right with  respect to those  Retracted  Shares that
Exchangeco is unable to redeem. In any such event, Exchangeco hereby agrees with
the Trustee and in favour of the Beneficiary to promptly  forward or cause to be
forwarded to the Trustee all relevant materials  delivered by the Beneficiary to
Exchangeco  or to the  transfer  agent  of the  Exchangeable  Shares  (including
without  limitation,  a copy of the  retraction  request  delivered  pursuant to
Section 6.1 of the Share Provisions) in connection with such proposed redemption
of the  Retracted  Shares and the Trustee will  thereupon  exercise the Exchange
Right with respect to the Retracted  Shares that  Exchangeco is not permitted to
redeem and will require  Parent to purchase such shares in  accordance  with the
provisions of this Article 5.

<PAGE>

                                      -15-

5.8  Taxes

     Upon any sale of  Exchangeable  Shares to Parent  pursuant to the  Exchange
Right or the Automatic  Exchange Rights,  the share  certificate or certificates
representing Parent Common Shares to be delivered in connection with the payment
of the  total  purchase  price  therefor  shall  be  issued  in the  name of the
Beneficiary  of the  Exchangeable  Shares  so  sold  or in  such  names  as such
Beneficiary may otherwise direct in writing, provided such direction is received
by Parent prior to the time such shares are issued, without charge to the holder
of the Exchangeable Shares so sold; provided, however, that such Beneficiary (a)
shall pay (and none of Parent,  Exchangeco  or the Trustee  shall be required to
pay) any  documentary,  stamp,  transfer  or other  taxes that may be payable in
respect of any transfer of such  Exchangeable  Shares to Parent or in respect of
the issuance or delivery of such Parent Common Shares to such Beneficiary or any
other Person  including,  without  limitation,  in the event that Parent  Common
Shares are being  issued or  transferred  in the name of a  clearing  service or
depositary or a nominee thereof, or (b) shall have evidenced to the satisfaction
of the Trustee, Parent and Exchangeco that such taxes, if any, have been paid.

5.9  Notice of Insolvency Event

     As soon as practicable  following the occurrence of an Insolvency  Event or
any event that with the giving of notice or the passage of time or both would be
an Insolvency Event,  Exchangeco and Parent shall give written notice thereof to
the  Trustee.  As soon as  practicable  following  the  receipt  of notice  from
Exchangeco  or Parent of the  occurrence  of an  Insolvency  Event,  or upon the
Trustee  becoming  aware of an Insolvency  Event,  the Trustee will mail to each
Beneficiary,  at the expense of Parent (such funds to be received in advance), a
notice of such  Insolvency  Event in the form  provided by Parent,  which notice
shall contain a brief statement of the rights of the Beneficiaries  with respect
to the Exchange Right.

5.10 Qualification of Parent Common Shares

     Parent  covenants  that  if any  Parent  Common  Shares  to be  issued  and
delivered  pursuant  to the  Exchange  Right,  the  Exchange  Put  Right  or the
Automatic Exchange Rights require registration or qualification with or approval
of or the filing of any document,  including any prospectus or similar document,
or the taking of any  proceeding  with or the obtaining of any order,  ruling or
consent from any  governmental  or regulatory  authority or stock exchange under
any Canadian or United States federal,  provincial or state law or regulation or
pursuant  to the  rules  and  regulations  of any  regulatory  authority  or the
fulfillment of any other Canadian or United States federal,  provincial or state
legal  requirement  before such shares may be issued and  delivered by Parent to
the initial  holder  thereof or in order that such  shares may be freely  traded
thereafter  (other than any  restrictions of general  application on transfer by
reason of a holder  being a "control  person" of Parent for purposes of Canadian
provincial  securities  law or an  "affiliate"  of Parent for purposes of United
States federal or state securities law), Parent will in good faith expeditiously
take all such  actions and do all such  things as are  reasonably  necessary  or
desirable to cause such Parent Common  Shares to be and remain duly  registered,
qualified or  approved.  Parent will in good faith  expeditiously  take all such
actions and do all such things as are reasonably necessary or desirable to cause
all Parent Common  Shares to be delivered  pursuant to the Exchange  Right,  the
Exchange Put Right or the Automatic Exchange Rights to be

<PAGE>

                                      -16-

listed,  quoted or posted  for  trading  on all stock  exchanges  and  quotation
systems on which  issued  Parent  Common  Shares  have been listed by Parent and
remain listed and are quoted or posted for trading at such time.

5.11 Parent Common Shares

     Parent hereby  represents,  warrants and  covenants  that the Parent Common
Shares  issuable as described  herein will be duly authorized and validly issued
as fully paid and  non-assessable and shall be free and clear of any lien, claim
or encumbrance.

5.12 Automatic Exchange on Liquidation of Parent

     Parent will give the Trustee written notice of each of the following events
at the time set forth below:

     (a)  in the event of any  determination by the Board of Directors of Parent
          to  institute   voluntary   liquidation,   dissolution  or  winding-up
          proceedings with respect to Parent or to effect any other distribution
          of assets of Parent among its  stockholders for the purpose of winding
          up its affairs,  as soon as practicable  and at least 60 days prior to
          the  proposed   effective  date  of  such  liquidation,   dissolution,
          winding-up or other distribution; and

     (b)  as soon as practicable  following the earlier of (A) receipt by Parent
          of  notice  of,  and (B)  Parent  otherwise  becoming  aware  of,  any
          instituted claim, suit,  petition or other proceedings with respect to
          the involuntary liquidation, dissolution or winding-up of Parent or to
          effect  any  other   distribution   of  assets  of  Parent  among  its
          stockholders  for the purpose of winding up its affairs,  in each case
          where  Parent has failed to contest in good faith any such  proceeding
          commenced  in  respect  of  Parent  within 30 days of  becoming  aware
          thereof.

     As soon as  practicable  following  receipt by the  Trustee  from Parent of
notice of any event (a "Liquidation  Event") contemplated by Sections 5.12(a) or
5.12(b), the Trustee will give notice thereof to the Beneficiaries.  Such notice
shall be provided to the Trustee by Parent and shall include a brief description
of the  automatic  exchange  of  Exchangeable  Shares for Parent  Common  Shares
provided for in this Section 5.12.

     In order that the  Beneficiaries  will be able to participate on a pro rata
basis with the holders of Parent Common Shares in the  distribution of assets of
Parent in connection  with a Liquidation  Event, on the fifth Business Day prior
to the effective date (the "Liquidation  Event Effective Date") of a Liquidation
Event,  all of the then outstanding  Exchangeable  Shares shall be automatically
exchanged for Parent Common Shares.  To effect such automatic  exchange,  Parent
shall  purchase  on the  fifth  Business  Day  prior  to the  Liquidation  Event
Effective  Date  each   Exchangeable   Share  then   outstanding   and  held  by
Beneficiaries,  and each Beneficiary shall sell the Exchangeable  Shares held by
it at such  time,  free and  clear of any  lien,  claim  or  encumbrance,  for a
purchase  price per share equal to the sum of: (i) the Current Market Price of a
Parent  Common Share on the fifth  Business Day prior to the  Liquidation  Event
Effective  Date,  which shall be satisfied in full by Parent  delivering  to the
Beneficiary  one  Parent  Common  Share,  and  (ii) to the  extent  not  paid by
Exchangeco on the designated payment date therefor, an

<PAGE>

                                      -17-

additional  amount equal 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 date of the  exchange.  Parent  shall  provide the
Trustee with an Officer's Certificate in connection with each automatic exchange
setting forth the calculation of the purchase price for each Exchangeable Share.

     On the fifth Business Day prior to the  Liquidation  Event  Effective Date,
the  closing  of the  transaction  of  purchase  and  sale  contemplated  by the
automatic  exchange of  Exchangeable  Shares for Parent  Common  Shares shall be
deemed  to  have  occurred,  and  each  Beneficiary  shall  be  deemed  to  have
transferred to Parent all of the Beneficiary's  right, title and interest in and
to such Beneficiary's  Exchangeable  Shares free and clear of any lien, claim or
encumbrance and the related interest in the Trust Estate,  Exchangeco shall have
no liability to pay an amount in respect of declared and unpaid dividends to any
Beneficiary  and each  such  Beneficiary  shall  cease  to be a  holder  of such
Exchangeable  Shares and Parent  shall  deliver or cause to be  delivered to the
Beneficiary the Parent Common Shares  deliverable upon the automatic exchange of
Exchangeable  Shares for Parent Common Shares and on the applicable payment date
shall  deliver to the Trustee for delivery to the  Beneficiary  a cheque for the
balance,  if any,  of the total  purchase  price for such  Exchangeable  Shares,
without  interest,  in each case less any amounts  withheld  pursuant to Section
5.13.  Concurrently with such Beneficiary ceasing to be a holder of Exchangeable
Shares,  the  Beneficiary  shall be considered and deemed for all purposes to be
the holder of the Parent Common Shares issued pursuant to the automatic exchange
of such  Beneficiary's  Exchangeable  Shares  for Parent  Common  Shares and the
certificates  held by the Beneficiary  previously  representing the Exchangeable
Shares  exchanged  by the  Beneficiary  with Parent  pursuant to such  automatic
exchange shall  thereafter be deemed to represent Parent Common Shares issued to
the Beneficiary by Parent pursuant to such automatic exchange.  Upon the request
of a Beneficiary  and the surrender by the  Beneficiary  of  Exchangeable  Share
certificates  deemed to represent  Parent Common Shares,  duly endorsed in blank
and  accompanied  by such  instruments  of  transfer  as Parent  may  reasonably
require,  Parent  shall  deliver  or cause to be  delivered  to the  Beneficiary
certificates  representing  the Parent Common Shares of which the Beneficiary is
the holder.

5.13 Withholding Rights

     Parent, Exchangeco and the Trustee shall be entitled to deduct and withhold
from any dividend or consideration otherwise payable under this Agreement to any
holder of  Exchangeable  Shares or Parent  Common Shares such amounts as Parent,
Exchangeco  or the Trustee is required to deduct and  withhold  with  respect to
such  payment  under the Income Tax Act  (Canada),  the United  States  Internal
Revenue  Code of 1986 or any  provision  of  federal,  provincial,  territorial,
state,  local or  foreign  tax law,  in each case as amended  or  succeeded,  or
entitled to  withhold  under  Section 116 of the Income Tax Act  (Canada) or any
corresponding provisions of provincial law. The Trustee may act on the advice of
counsel  with  respect  to such  matters.  To the  extent  that  amounts  are so
withheld, such withheld amounts shall be treated for all purposes 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 are actually remitted
to the appropriate  taxing authority.  To the extent that the amount so required
or entitled to be deducted or withheld from any payment to a holder  exceeds the
cash  portion of the  consideration  otherwise  payable to the  holder,  Parent,
Exchangeco and the Trustee are hereby authorized to sell

<PAGE>

                                      -18-

or  otherwise  dispose of such portion of the  consideration  as is necessary to
provide sufficient funds to Parent,  Exchangeco or the Trustee,  as the case may
be, to enable it to comply with such  deduction or  withholding  requirement  or
entitlement  and  Parent,  Exchangeco  or the  Trustee  shall  notify the holder
thereof and remit to such holder any  unapplied  balance of the net  proceeds of
such sale.

5.14 No Fractional Shares

     A holder of an Exchangeable  Share shall not be entitled to any fraction of
a Parent Common Share upon the exercise of the Exchange Right,  the Exchange Put
Right or Automatic  Exchange Rights  hereunder and no certificates  representing
any such fractional  interest shall be issued and such holder otherwise entitled
to a fractional  interest will receive for such fractional  interest from Parent
on the designated  payment date to the extent not paid by Callco or Exchangeco a
cash payment equal to such fractional  interest multiplied by the Current Market
Price.

          Exchangeable  Shares and other requisite documents and distributing to
          such Beneficiaries  Parent Common Shares and cheques, if any, to which
          such  Beneficiaries  are  entitled  upon the  exercise of the Exchange
          Right,  the Exchange Put Right or pursuant to the  Automatic  Exchange
          Rights, as the case may be;

     (f)  holding title to the Trust Estate;

     (g)  investing any moneys  forming,  from time to time, a part of the Trust
          Estate as provided in this Agreement;

     (h)  taking  action  on  its  own  initiative  or  at  the  direction  of a

     (i)  taking  such  other  actions  and  doing  such  other  things  as  are

shall have (and is granted)  such  incidental  and  additional  rights,  powers,
duties  and  authority  not in  conflict  with  any of the  provisions  of  this
Agreement as the Trustee, acting in good faith and in the reasonable exercise of
its  discretion,  may deem  necessary,  appropriate  or  desirable to effect the
purpose of the Trust. Any exercise of such discretionary rights,  powers, duties
and  authorities by the Trustee shall be final,  conclusive and binding upon all
Persons.

     The  Trustee in  exercising  its  rights,  powers,  duties and  authorities
hereunder  shall  act  honestly  and in good  faith  and with a view to the best
interests of the Beneficiaries and shall exercise the care,  diligence and skill
that a reasonably prudent trustee would exercise in comparable circumstances.

     The Trustee shall not be bound to give notice or do or take any act, action
or proceeding by virtue of the powers conferred on it hereby unless and until it
shall be  specifically  required to do so under the terms hereof;  nor shall the
Trustee be required to take any notice of, or to do, or to take any act,  action
or proceeding  as a result of any default or breach of any provision  hereunder,
unless and until  notified in writing of such default or breach,  which  notices
shall  distinctly  specify  the  default or breach  desired to be brought to the
attention of the Trustee,  and in the absence of such notice the Trustee may for
all purposes of this Agreement conclusively assume that no default or breach has
been  made  in the  observance  or  performance  of any of the  representations,
warranties, covenants, agreements or conditions contained herein.

     The  Trustee  represents  to  Parent  and  Exchangeco  that at the  date of
execution and delivery of this  Agreement  there exists no material  conflict of
interest in the role of the Trustee as a fiduciary hereunder and the role of the
Trustee  in any other  capacity.  The  Trustee  shall,  within 90 days  after it
becomes aware that such material  conflict of interest exists,  either eliminate
such  material  conflict of interest or resign in the manner and with the effect
specified in Article 10. If,  notwithstanding  the foregoing  provisions of this
Section 7.2, the Trustee has such a material conflict of interest,  the validity
and enforceability of this Agreement shall not be

<PAGE>

                                      -20-

affected  in any  manner  whatsoever  by reason  only of the  existence  of such
material  conflict  of  interest.  If  the  Trustee  contravenes  the  foregoing
provisions  of this Section 7.2, any  interested  party may apply to the Supreme
Court of British  Columbia  for an order that the Trustee be replaced as Trustee
hereunder.

7.3  Dealings with Transfer Agents, Registrars, etc.

     Parent and Exchangeco irrevocably authorize the Trustee, from time to time,

          and  transfer  agents,  and  with  any such  subsequent  registrar  or
          transfer agent, of the  Exchangeable  Shares and Parent Common Shares;
          and

     (b)  requisition,  from  time to  time,  (i) from  any  such  registrar  or

          maintained  by it which the  Trustee  may  reasonably  require for the
          discharge of its duties and responsibilities  under this Agreement and
          (ii)  from  the  transfer  agent  of  Parent  Common  Shares,  and any
          subsequent  transfer  agent of such  shares,  the  share  certificates
          issuable upon the exercise from time to time of the Exchange Right and
          pursuant to the Automatic  Exchange Rights in the manner  specified in
          Article 5.

     Parent and Exchangeco irrevocably authorize their respective registrars and
transfer agents to comply with all such requests.  Parent covenants that it will
supply its transfer agent with duly executed share  certificates for the purpose
of  completing  the  exercise  from time to time of the  Exchange  Right and the
Automatic Exchange Rights, in each case pursuant to Article 5.

7.4  Books and Records

     The Trustee shall keep available for inspection by Parent and Exchangeco at

          Right,  if any,  and  the  aggregate  number  of  Exchangeable  Shares
          received by the Trustee on behalf of Beneficiaries in consideration of
          the  delivery  by or on behalf of  Parent of Parent  Common  Shares in
          connection with the Exchange Right and the Exchange Put Right,  during
          the fiscal year of Parent ended on such date; and

<PAGE>

                                      -21-

     (c)  any action taken by the Trustee in the performance of its duties under
          this Agreement which it had not previously  reported and which, in the
          Trustee's opinion, materially affects the Trust Estate.

7.5  Income Tax Returns and Reports

     The Trustee shall, to the extent  necessary,  prepare and file on behalf of
the Trust  appropriate  United  States and  Canadian  income tax returns and any
other returns or reports as may be required by applicable law or pursuant to the
rules and regulations of any securities exchange or other trading system through
which the Exchangeable Shares are traded. In connection  therewith,  the Trustee
may obtain the advice and  assistance of such experts or advisors as the Trustee
considers  necessary or  advisable  (who may be experts or advisors to Parent or
Exchangeco).  If  requested by the Trustee,  Parent or  Exchangeco  shall retain
qualified  experts or advisors for the purpose of  providing  such tax advice or
assistance.

7.6  Indemnification Prior to Certain Actions by Trustee

     The Trustee  shall  exercise  any or all of the rights,  duties,  powers or
authorities vested in it by this Agreement at the request, order or direction of
any  Beneficiary  upon such  Beneficiary  furnishing  to the Trustee  reasonable
funding, security or indemnity against the costs, expenses and liabilities which
may be incurred by the Trustee therein or thereby,  provided that no Beneficiary
shall be obligated  to furnish to the Trustee any such  security or indemnity in
connection with the exercise by the Trustee of any of its rights, duties, powers
and authorities  with respect to the Special Voting Share pursuant to Article 4,
subject to Section 7.15, and with respect to the Exchange Right and the Exchange
Put Right  pursuant to Article 5, subject to Section  7.15,  and with respect to
the Automatic Exchange Rights pursuant to Article 5, subject to Section 7.15.

     None of the  provisions  contained  in this  Agreement  shall  require  the
Trustee to expend or risk its own funds or otherwise incur  financial  liability
in the exercise of any of its rights,  powers,  duties,  or  authorities  unless
funded, given security and indemnified as aforesaid.

7.7  Action of Beneficiaries

     No  Beneficiary  shall  have the right to  institute  any  action,  suit or
proceeding or to exercise any other remedy  authorized by this Agreement for the
purpose  of  enforcing  any of its rights or for the  execution  of any trust or
power  hereunder  unless the  Beneficiary  has  requested the Trustee to take or
institute  such action,  suit or  proceeding  and furnished the Trustee with the
funding,  security or indemnity referred to in Section 7.6 and the Trustee shall
have failed to act within a reasonable  time  thereafter.  In such case, but not
otherwise, the Beneficiary shall be entitled to take proceedings in any court of
competent jurisdiction such as the Trustee might have taken; it being understood
and  intended  that no one or more  Beneficiaries  shall  have any  right in any
manner  whatsoever to affect,  disturb or prejudice the rights hereby created by
any such action,  or to enforce any right  hereunder or the Voting  Rights,  the
Exchange Right, the Exchange Put Right or the Automatic Exchange Rights,  except
subject to the conditions and in the manner herein provided, and that all powers
and trusts hereunder shall be exercised and all proceedings

<PAGE>

                                      -22-

at law shall be instituted,  had and  maintained by the Trustee,  except only as
herein provided, and in any event for the equal benefit of all Beneficiaries.

7.8  Reliance Upon Declarations

     The Trustee shall not be considered  to be in  contravention  of any of its
rights,  powers, duties and authorities hereunder if, when required, it acts and
relies in good faith upon  statutory  declarations,  certificates,  opinions  or
reports  furnished  pursuant to the provisions hereof or required by the Trustee
to be  furnished  to it in  the  exercise  of its  rights,  powers,  duties  and
authorities hereunder if such statutory declarations,  certificates, opinions or

other applicable provisions of this Agreement.

     Parent or Exchangeco  shall  furnish to the Trustee  evidence of compliance

          management of the Trust.

7.11 Investment of Moneys Held by Trustee

     Unless  otherwise  provided  in this  Agreement,  any moneys  held by or on
behalf of the Trustee which under the terms of this Agreement may or ought to be
invested  or which may be on  deposit  with the  Trustee  or which may be in the
hands of the  Trustee may be invested  and  reinvested  in the name or under the
control of the Trustee in securities in which, under the laws of the Province of
British Columbia,  trustees are authorized to invest trust moneys, provided that
such  securities  are stated to mature within two years after their  purchase by
the  Trustee,  and the  Trustee  shall so  invest  such  moneys  on the  written
direction of Exchangeco.  Pending the  investment of any moneys as  hereinbefore
provided,  such  moneys  may be  deposited  in the  name of the  Trustee  in any
chartered  bank in Canada or in the  deposit  department  of the  Trustee or any
other  specified loan or trust company  authorized to accept  deposits under the

7.13 Trustee Not Bound to Act on Request

     Except as in this Agreement otherwise  specifically  provided,  the Trustee
shall not be bound to act in accordance  with any direction or request of Parent
or Exchangeco or of the directors thereof until a duly authenticated copy of the
instrument or resolution  containing  such  direction or request shall have been
delivered  to the  Trustee,  and the Trustee  shall be empowered to act upon any
such copy  purporting  to be  authenticated  and  believed  by the Trustee to be
genuine.

7.14 Authority to Carry on Business

     The  Trustee  represents  to  Parent  and  Exchangeco  that at the  date of
execution and delivery by it of this  Agreement it is authorized to carry on the
business  of a  trust  company  in  each  of the  provinces  of  Canada  but if,
notwithstanding  the  provisions  of  this  Section  7.14,  it  ceases  to be so
authorized  to  carry on  business,  the  validity  and  enforceability  of this
Agreement and the Voting Rights,  the Exchange Right and the Automatic  Exchange
Rights  shall not be  affected in any manner  whatsoever  by reason only of such
event but the Trustee  shall,  within 90 days after  ceasing to be authorized to
carry on the  business  of a trust  company in any  province  of Canada,  either
become so  authorized  or resign in the manner and with the effect  specified in
Article 10.

7.15 Conflicting Claims

     If  conflicting  claims or demands are made or asserted with respect to any
interest  of  any  Beneficiary  in  any  Exchangeable   Shares,   including  any
disagreement   between  the  heirs,   representatives,   successors  or  assigns
succeeding  to  all or  any  part  of the  interest  of any  Beneficiary  in any
Exchangeable  Shares,  resulting in conflicting  claims or demands being made in
connection with such interest,  then the Trustee shall be entitled,  in its sole
discretion, to refuse to recognize or to comply with any such claims or demands.
In so  refusing,  the  Trustee  may elect not to  exercise  any  Voting  Rights,
Exchange Right,  Exchange Put Right or Automatic Exchange Rights subject to such
conflicting  claims or demands  and, in so doing,  the  Trustee  shall not be or
become  liable to any  Person on  account  of such  election  or its  failure or
refusal to comply with any such conflicting claims or demands. The Trustee shall
be entitled to continue to refrain from acting and to refuse to act until:

     (a)  the rights of all adverse claimants with respect to the Voting Rights,
          Exchange  Right,  Exchange  Put  Right or  Automatic  Exchange  Rights
          subject to such conflicting claims or demands have been adjudicated by

          demands have been  conclusively  settled by a valid written  agreement
          binding on all such adverse claimants, and the Trustee shall have been

8.1  Fees and Expenses of the Trustee

     Parent  and  Exchangeco  jointly  and  severally  agree to pay the  Trustee
reasonable  compensation  for all of the  services  rendered  by it  under  this
Agreement and will reimburse the Trustee for all reasonable expenses (including,
but not limited to, taxes other than taxes based on the net income or capital of
the  Trustee,  fees paid to legal  counsel and other  experts and  advisors  and
travel expenses) and  disbursements,  including the cost and expense of any suit
or  litigation  of any character  and any  proceedings  before any  governmental

this Agreement;  provided that Parent and Exchangeco shall have no obligation to
reimburse  the  Trustee  for any  expenses or  disbursements  paid,  incurred or

                   INDEMNIFICATION AND LIMITATION OF LIABILITY

9.1  Indemnification of the Trustee

     Parent and  Exchangeco  jointly and  severally  agree to indemnify and hold
harmless the Trustee and each of its directors and officers  (collectively,  the
"Indemnified  Parties") against all claims, losses,  damages,  reasonable costs,
penalties,  fines and reasonable expenses (including  reasonable expenses of the
Trustee's legal counsel) which, without fraud, negligence,  wilful misconduct or
bad  faith on the part of such  Indemnified  Party,  may be  paid,  incurred  or
suffered  by the  Indemnified  Party by reason  or as a result of the  Trustee's
acceptance or  administration  of the Trust,  its compliance with its duties set
forth in this  Agreement,  or any written or oral  instruction  delivered to the
Trustee by Parent or Exchangeco pursuant hereto.

<PAGE>

                                      -26-

     In no case shall Parent or  Exchangeco  be liable under this  indemnity for
any claim against any of the  Indemnified  Parties  unless Parent and Exchangeco
shall be notified by the Trustee in  accordance  with the  provisions of Section
14.3 of the written  assertion of a claim or of any action commenced against the
Indemnified  Parties,  promptly after any of the Indemnified  Parties shall have
received any such written  assertion of a claim or shall have been served with a
summons or other first legal  process  giving  information  as to the nature and
basis of the  claim.  Subject to (ii)  below,  Parent  and  Exchangeco  shall be
entitled to  participate  at their own expense in the defence and, if Parent and
Exchangeco so elect at any time after receipt of such notice, either of them may
assume the defence of any suit  brought to enforce  any such claim.  The Trustee
shall have the right to employ separate counsel in any such suit and participate
in the defence  thereof,  but the fees and expenses of such counsel  shall be at
the expense of the Trustee  unless:  (i) the employment of such counsel has been
authorized by Parent or  Exchangeco;  or (ii) the named parties to any such suit
include  both the Trustee and Parent or  Exchangeco  and the Trustee  shall have
been advised by counsel  acceptable to Parent or Exchangeco,  acting reasonably,
that there may be one or more legal  defences  available to the Trustee that are
different  from or in addition to those  available to Parent or  Exchangeco  and
that, in the judgment of such counsel, would present a conflict of interest were
a joint  representation  to be undertaken  (in which case Parent and  Exchangeco
shall  not have the right to assume  the  defence  of such suit on behalf of the
Trustee but shall be liable to pay the  reasonable  fees and expenses of counsel
for the Trustee). This indemnity shall survive the termination of this Agreement
and the resignation or removal of the Trustee.

9.2  Limitation of Liability

     The Trustee shall not be held liable for any loss which may occur by reason
of  depreciation  of the  value  of any  part of the  Trust  Estate  or any loss
incurred on any  investment of funds pursuant to this  Agreement,  except to the
extent that such loss is  attributable to the fraud,  negligence,  recklessness,
wilful misconduct or bad faith on the part of the Trustee.

                                   ARTICLE 10
                                CHANGE OF TRUSTEE

10.1 Resignation

     The Trustee, or any trustee hereafter appointed,  may at any time resign by
giving  written notice of such  resignation to Parent and Exchangeco  specifying
the date on which it desires to resign,  provided  that such notice shall not be
given less than thirty (30) days before  such  desired  resignation  date unless
Parent and Exchangeco otherwise agree and provided further that such resignation
shall not take effect until the date of the  appointment of a successor  trustee
and the acceptance of such appointment by the successor trustee.  Upon receiving
such notice of  resignation,  Parent and  Exchangeco  shall  promptly  appoint a
successor trustee, which shall be a corporation organized and existing under the
laws of Canada and authorized to carry on the business of a trust company in all
provinces of Canada, by written instrument in duplicate, one copy of which shall
be delivered to the  resigning  trustee and one copy to the  successor  trustee.
Failing the  appointment  and  acceptance  of a successor  trustee,  a successor
trustee may be  appointed  by order of a court of  competent  jurisdiction  upon
application  of one or more of the parties to this  Agreement.  If the  retiring
trustee is the party initiating an application for the

<PAGE>

                                      -27-

appointment   of  a  successor   trustee  by  order  of  a  court  of  competent
jurisdiction,  Parent and  Exchangeco  shall be jointly and severally  liable to
reimburse  the retiring  trustee for its legal costs and expenses in  connection
with same.

10.2 Removal

     The Trustee, or any trustee hereafter appointed,  may (provided a successor
trustee is  appointed)  be  removed at any time on not less than 30 days'  prior
notice by written  instrument  executed by Parent and Exchangeco,  in duplicate,
one copy of which shall be  delivered  to the trustee so removed and one copy to
the successor trustee.

10.3 Successor Trustee

     Any successor  trustee  appointed as provided  under this  Agreement  shall
execute, acknowledge and deliver to Parent and Exchangeco and to its predecessor
trustee an instrument  accepting such appointment.  Thereupon the resignation or
removal of the  predecessor  trustee shall become  effective and such  successor
trustee,  without any further act, deed or conveyance,  shall become vested with
all the rights,  powers,  duties and obligations of its  predecessor  under this
Agreement,  with the like  effect  as if  originally  named as  trustee  in this
Agreement.  However,  on the written  request of Parent and Exchangeco or of the
successor trustee, the trustee ceasing to act shall, upon payment of any amounts
then due it pursuant to the provisions of this Agreement, execute and deliver an
instrument  transferring to such successor  trustee all the rights and powers of
the trustee so ceasing to act. Upon the request of any such  successor  trustee,
Parent,  Exchangeco  and such  predecessor  trustee  shall  execute  any and all
instruments in writing for more fully and certainly vesting in and confirming to
such successor trustee all such rights and powers.

10.4 Notice of Successor Trustee

     Upon acceptance of appointment by a successor  trustee as provided  herein,
Parent and Exchangeco  shall cause to be mailed notice of the succession of such
trustee  hereunder  to each  Beneficiary  specified  in a  List.  If  Parent  or
Exchangeco  shall  fail to cause such  notice to be mailed  within 10 days after
acceptance of appointment by the successor trustee,  the successor trustee shall
cause such notice to be mailed at the expense of Parent and Exchangeco.

11.1 Certain Requirements in Respect of Combination, etc.

     As long as any  outstanding  Exchangeable  Shares  are owned by any  Person
other than Parent or any of its  Affiliates,  Parent  shall not  consummate  any
transaction  (whether by way of reconstruction,  reorganization,  consolidation,
arrangement,  merger,  transfer,  sale,  lease  or  otherwise)  whereby  all  or
substantially  all of its  undertaking,  property  and assets  would  become the
property  of any other  Person  or, in the case of a merger,  of the  continuing
corporation or other entity resulting therefrom unless, but may do so if:

<PAGE>

                                      -28-

     (a)  such other Person or  continuing  corporation  or, in the event of any
          merger,  amalgamation or similar transaction pursuant to which holders
          of shares in Parent are  entitled to receive  shares in the capital of
          any  corporation or other legal entity other than such other Person or
          continuing corporation, then such corporation or legal entity (in each
          case, the "Parent  Successor") by operation of law,  becomes,  without
          more,  bound by the terms and  provisions of this Agreement or, if not
          so  bound,   executes,   prior  to  or   contemporaneously   with  the
          consummation of such transaction,  an agreement supplemental hereto or
          otherwise  agrees to become bound by the terms and  provisions of this
          Agreement,  in either case  together with such other  instruments  (if
          any)  as  are  reasonably  necessary  or  advisable  to  evidence  the
          assumption by the Parent Successor of liability for all moneys payable
          and  property  deliverable  hereunder  and the covenant of such Parent
          Successor to pay and deliver or cause to be delivered the same and its
          agreement to observe and perform all the covenants and  obligations of
          Parent under this Agreement; and

     (b)  such  transaction  shall, to the  satisfaction of the Trustee,  acting
          reasonably,  and in the opinion of legal  counsel to the  Trustee,  be
          upon such terms and conditions as substantially to preserve and not to
          impair in any material respect any of the rights,  duties,  powers and
          authorities of the Trustee or of the Beneficiaries hereunder.

11.2 Vesting of Powers in Successor

     Whenever  the  conditions  of  Section  11.1 have been  duly  observed  and
performed, the Trustee, Parent Successor,  Exchangeco and Parent, as applicable,
shall, if required by Section 11.1,  execute and deliver the supplemental  trust
agreement  provided  for in  Article 12 and  thereupon  Parent  Successor  shall
possess  and from time to time may  exercise  each and every  right and power of
Parent under this  Agreement  in the name of Parent or otherwise  and any act or
proceeding by any provision of this  Agreement  required to be done or performed
by the Board of Directors of Parent, or any officers of Parent,  may be done and
performed with like force and effect by the directors or officers of such Parent
Successor.

11.3 Wholly-Owned Subsidiaries

     Nothing herein shall be construed as preventing the  amalgamation or merger
of any wholly-owned  direct or indirect subsidiary of Parent with or into Parent
or the  winding-up,  liquidation or dissolution  of any  wholly-owned  direct or
indirect  subsidiary  of Parent  (if all of the  assets of such  subsidiary  are
transferred to Parent or another  wholly-owned  direct or indirect subsidiary of
Parent) or any other  distribution of the assets of any  wholly-owned  direct or
indirect  subsidiary of Parent among the shareholders of such subsidiary for the
purpose of winding  up its  affairs,  and any such  transactions  are  expressly
permitted by this Article 11.

     (b)  making such amendments or  modifications  not  inconsistent  with this
          Agreement as may be necessary or desirable  with respect to matters or
          questions  which,  in the good faith opinion of the Board of Directors
          of each of Parent and  Exchangeco  and in the opinion of the  Trustee,
          having  in mind the best  interests  of the  Beneficiaries,  it may be
          expedient  to make,  provided  that such Boards of  Directors  and the

changed,  this Agreement shall forthwith be amended and modified as necessary in
order that it shall apply with full force and effect,  mutatis mutandis,  to all
new  securities  into which Parent Common Shares or the  Exchangeable  Shares or

          based  on the  advice  of  counsel,  will  not be  prejudicial  to the
          interests  of the  Beneficiaries  or are, in the opinion of counsel to
          the Trustee,  necessary or advisable in order to incorporate,  reflect
          or  comply  with any  legislation  the  provisions  of which  apply to
          Parent, Exchangeco, the Trustee or this Agreement; and

     (c)  for any other  purposes not  inconsistent  with the provisions of this

                                AFFILIATE LETTER

                                                                  April 12, 2004

At Road, Inc.

Fremont, California 94538

Ladies and Gentlemen:

     I have been  advised  that as of the date of this letter I may be deemed to
be an "affiliate" of MDSI Mobile Data  Solutions Inc.  ("Company"),  as the term
"affiliate" is defined for purposes of paragraphs (c) and (d) of Rule 145 of the
rules and  regulations  (the  "Rules and  Regulations")  of the  Securities  and
Exchange  Commission  (the "SEC") under the  Securities  Act of 1933, as amended
(the "1933 Act"). Pursuant to the terms of the Combination  Agreement,  dated as
of April 12, 2003 (the "Combination Agreement"), among At Road, Inc., a Delaware
corporation  ("Parent"),  Orion Exchangeco,  Ltd., a corporation organized under
the Business  Corporations  Act  (British  Columbia)  and  Company,  Parent will
acquire all of the  outstanding  share  capital of Company (the  "Arrangement").
Capitalized  terms used in this letter agreement  without  definition shall have
the meanings assigned to them in the Combination Agreement.

     As a result of the  Arrangement,  I may  receive  Parent  Common  Shares or
Exchangeable  Shares in  exchange  for shares (or upon  exercise  of options for
shares) owned by me of common shares, no par value, of Company.

     1.   I  represent,  warrant  and  covenant  to  Parent  that in the event I
receive  any  Parent  Common  Shares or  Exchangeable  Shares as a result of the
Arrangement:

          A. I shall not make any sale,  transfer  or other  disposition  of the
     Parent Common Shares or Exchangeable Shares in violation of the 1933 Act or
     the Rules and Regulations.

          B. I have carefully read this letter and discussed the requirements of
     this  letter  and other  applicable  limitations  upon my  ability to sell,
     transfer or otherwise  dispose of the Parent Common Shares or  Exchangeable
     Shares, to the extent I felt necessary, with my counsel.

          C. I have been advised that the issuance of Parent  Common  Shares and
     Exchangeable Shares in connection with the transactions contemplated by the
     Combination   Agreement  will  be  either  (A)  exempt  from   registration
     requirements  under the 1933 Act,  pursuant to Section  3(a)(10)  under the
     1933  Act or  (B)  registered  on a  registration  statement  on  Form  S-3
     promulgated under the 1933 Act and, in either such case, the resale of such
     Parent Common Shares or Exchangeable  Shares may be subject to restrictions
     set forth in Rule 145 under the 1933 Act. I have been advised that, because
     at the time the Arrangement is submitted for a vote of the  shareholders of
     Company I may be  deemed to be an  affiliate  of  Company,  I may not sell,
     transfer or otherwise

     dispose of the Parent Common Shares or Exchangeable  Shares issued to me in
     the  Arrangement,  or any Parent  Common Shares issued upon exchange of the
     Exchangeable Shares issued to me as a result of the Arrangement, unless (i)
     such sale,  transfer or other  disposition  is made in conformity  with the
     limitations  of Rule 145  promulgated  by the SEC under the 1933 Act,  (ii)
     such sale, transfer or other disposition has been registered under the 1933
     Act or (iii) in the  opinion of counsel  reasonably  acceptable  to Parent,
     such  sale,   transfer  or  other  disposition  is  otherwise  exempt  from
     registration under the 1933 Act.

          D. (i) I understand that there will be placed on the  certificates for
     the  Parent  Common  Shares  or  Exchangeable  Shares  issued to me, or any
     substitutions therefor, a legend stating in substance:

          "THE  SHARES   REPRESENTED  BY  THIS  CERTIFICATE  WERE  ISSUED  IN  A
          TRANSACTION TO WHICH RULE 145 PROMULGATED  UNDER THE SECURITIES ACT OF
          1933 APPLIES.  THE SHARES  REPRESENTED BY THIS CERTIFICATE MAY ONLY BE
          TRANSFERRED  IN  ACCORDANCE  WITH  THE  TERMS  OF AN  AGREEMENT  DATED
          __________,  2004 BETWEEN THE  REGISTERED  HOLDER  HEREOF AND AT ROAD,
          INC., A COPY OF WHICH AGREEMENT IS ON FILE AT THE PRINCIPAL OFFICES OF
          ASTEROID, INC."

          (ii) If a sale or  transfer  is made prior to the above  legend  being
     removed pursuant to paragraph 2 below,  certificates  with the above legend
     will be  substituted by delivery of  certificates  without such legend upon
     delivery of a declaration to Parent (the "Declaration"),  which Declaration
     shall be reasonably  satisfactory in form and substance to Parent, that the
     requirements of Rule 145(d)(1) have been complied with.

          E. I understand  that unless a sale or transfer is made in  accordance
     with the  provisions  of  paragraph  1.C.  above,  or the legend is removed
     pursuant to  paragraph 2, Parent  reserves  the right to put the  following
     legend on the certificates issued to my transferee:

          "THE SHARES  REPRESENTED BY THIS  CERTIFICATE HAVE NOT BEEN REGISTERED
          UNDER THE  SECURITIES  ACT OF 1933 AND WERE ACQUIRED FROM A PERSON WHO
          RECEIVED  SUCH SHARES IN A TRANSACTION  TO WHICH RULE 145  PROMULGATED
          UNDER  THE  SECURITIES  ACT OF 1933  APPLIES.  THE  SHARES  HAVE  BEEN
          ACQUIRED BY THE HOLDER NOT WITH A VIEW TO, OR FOR RESALE IN CONNECTION
          WITH,  ANY  DISTRIBUTION  THEREOF WITHIN THE MEANING OF THE SECURITIES
          ACT OF 1933  AND MAY NOT BE SOLD,  PLEDGED  OR  OTHERWISE  TRANSFERRED
          EXCEPT  IN  ACCORDANCE   WITH  AN  EXEMPTION  FROM  THE   REGISTRATION
          REQUIREMENTS OF THE SECURITIES ACT OF 1933."

          F.  Execution of this letter  should not be considered an admission on
     my part that I am an  "affiliate"  of  Company  as  described  in the first
     paragraph  of this  letter,  nor as a  waiver  of any  rights I may have to
     object to any  claim  that I am such an  affiliate  on or after the date of
     this letter.

     2.   By Parent's  acceptance  of this letter,  Parent hereby agrees with me
that:

          Unless previously sold pursuant to the applicable requirements of Rule
     145, it is  understood  and agreed that  certificates  with the legends set
     forth in paragraphs  1.D. and l.E. above will be substituted by delivery of
     certificates  without  such legends if (i) one year shall have elapsed from
     the date the undersigned  acquired the Parent Common Shares or Exchangeable
     Shares received in the Arrangement and the provisions of Rule 145(d)(2) are
     then available to the  undersigned,  (ii) two years shall have elapsed from
     the date the undersigned  acquired the Parent Common Shares or Exchangeable
     Shares received in the Arrangement and the provisions of Rule 145(d)(3) are
     then applicable to the undersigned,  or (iii) Parent has received either an
     opinion  of  counsel,   which  opinion  and  counsel  shall  be  reasonably
     satisfactory to Parent, or a "no action" letter obtained by the undersigned
     from the staff of the SEC, to the effect that the  restrictions  imposed by
     Rule 145 under the 1933 Act no longer apply to the undersigned.

          For as long as resales of any shares of Parent  Common Shares owned by
     me are subject to Rule 145, Parent will use its reasonable  efforts to make
     all filings of the nature  specified in paragraph  (c)(1) of Rule 144 under
     the 1933 Act.  Upon  receipt of a properly  completed  Declaration,  Parent
     shall use its  reasonable  best efforts to instruct  its transfer  agent to
     deliver  unlegended shares in accordance with the terms of the transfer set
     forth in the Declaration as soon as practicable  following  receipt of such
     Declaration.

                                        Very truly yours,

                                        ---------------------------------------
