limited partnership,  syndicate, association, joint venture company, corporation
or joint stock company,  nor shall the Trustee or the Unitholders or any of them
or any  Person  be, or be deemed to be,  treated  in any way  whatsoever  as, or

herein) are vested exclusively in the Trustee, and the Unitholders shall have no
interest  therein  other  than  the  rights   specifically  set  forth  in  this
Declaration  of  Trust  and  shall  have no  right  to  compel  or call  for any
partition,  division,  dividend or  distribution of the Trust Fund or any of the
assets of the Trust except as specifically  provided herein.  The Units shall be
personal  property and shall  confer upon the holders  thereof only the interest
and rights  specifically  set forth in this  Declaration of Trust. No Unitholder
has or is  deemed  to have any right of  ownership  in any of the  assets of the
Trust.

2.6   Liability of Unitholders

the Trustee or by any other Person pursuant to this Declaration of Trust or with
respect  to any act or  omission  of the  Trustee  or any  other  Person  in the

obligation,  power,  discretion or authority  conferred upon the Trustee or such
other Person  hereunder or with respect to any  transaction  entered into by the

any  other  Person  on  behalf of or in  connection  with the  Trust;  provided,
however, to the extent that,  notwithstanding the foregoing, any Unitholders are
held by a court of competent  jurisdiction  to be subject to any such liability,
such liability  shall be enforceable  only against,  and shall be satisfied only
out of, the Trust Fund.

personal liability) include a provision substantially to the following effect:

      The  parties  hereto  acknowledge  that  the  [Trustee]  [Corporation]  is
      entering  into this  agreement  solely [in its  capacity as  Trustee]  [on
      behalf] of the Trust and the  obligations of the Trust hereunder shall not
      be  personally  binding  upon the  [Trustee]  [Corporation]  or any of the
      Unitholders  of the Trust and that any  recourse  against the Trust [, the
      Trustee] [, the Corporation] or any Unitholder in any manner in respect of
      any  indebtedness,  obligation or liability of the Trust arising hereunder
      or  arising  in  connection  herewith  or from the  matters  to which this
      agreement  relates,  if any,  including without limitation claims based on
      negligence  or  otherwise  tortious  behaviour,  shall be limited  to, and
      satisfied  only out of, the Trust Fund as  defined in the  Declaration  of
      Trust dated August 2, 1996 and  restated  November 6, 2002 as amended from
      time to time.

      The omission of such a provision  from any such written  instrument  shall
not operate to impose  personal  liability  on the  Trustee,  the  Manager,  the
Corporation or any Unitholder.

2.8   Head Office of Trust

      The head  office of the Trust  shall be located at 4700,  150 - 6th Avenue

                                     UNITS

3.1   Designation and Number of Units

      The  beneficial  interests in the Trust shall be divided into interests of
one class,  described and  designated  as Units,  which shall be entitled to the
rights and subject to

                                     - 11 -



the  limitations,  restrictions  and  conditions  set out herein.  The aggregate
number of Units which may be authorized and issued hereunder is unlimited.

3.2   Offerings of Units

      Units may be issued at the times,  to the persons,  for the  consideration
and  on the  terms  and  conditions  that  the  Corporation  determines.  Units,
including rights to acquire Units, may be offered pursuant to Offering Documents
or other  agreements or  arrangements  on such terms and  conditions and at such
time or times as the Corporation may determine.

3.3   Ranking of Units

      Each Unit represents an equal fractional  undivided beneficial interest in
the Trust  Fund.  All Units  Outstanding  from time to time shall be entitled to
equal shares in any  distributions by the Trust and, in the event of termination
of the  Trust,  in the net  assets of the  Trust.  All Units  shall  rank  among
themselves equally and rateably without  discrimination,  preference or priority
whatever may be the actual date or terms of issue thereof.

3.4   Units Non-Assessable

      Units shall be issued only when fully paid and the  Unitholders  shall not
thereafter  be  required  to make any  further  contribution  to the Trust  with
respect to such Units; provided however  notwithstanding the foregoing the Units
to be issued  under an  Offering  may be issued for a  consideration  payable in
instalments  and the Trust may take  security over such Units to be issued under
any such Offering as security for unpaid  instalments  and may assign all or any
part of its interests in that security.

3.5   No Conversion, Retraction, Redemption or Pre-Emptive Rights

      There are no  conversion,  retraction,  redemption or  pre-emptive  rights
attaching to the Units, other than as set forth herein.

3.6   No Fractional Units

      Fractions of Units shall not be issued.

3.7   Transferability of Units

      The Units are transferable.

3.8   Non-Resident Unitholders

      At no time may more  than  one-half  of the  Outstanding  Units be held by
non-residents of Canada  ("non-residents")  within the meaning of the Income Tax
Act. If

                                     - 12 -



at any time the Trustee becomes aware, as a result of requiring  declarations as
to beneficial  ownership  under Section 8.11 or otherwise,  that the  beneficial
owners of 49% of the Units then  Outstanding are or may be non-residents or that
such a situation is imminent, the Trustee may make a public announcement thereof
and shall  not  accept a  subscription  for Units  from or issue or  register  a
transfer of Units to a Person unless the Person provides a declaration  pursuant
to Section 8.11 that the Person is not a non-resident.  If,  notwithstanding the
foregoing,  the  Trustee  determines  that a  majority  of the Units are held by
non-residents,  the Trustee may send a notice to non-resident  holders of Units,
chosen in inverse order to the order of acquisition or  registration  or in such
other manner as the Trustee may consider  equitable and  practicable,  requiring
them to sell their  Units or a  specified  portion  thereof  within a  specified
period of not less than 60 days. If the  Unitholders  receiving such notice have
not within  such  period  sold the  specified  number of Units or  provided  the
Trustee with satisfactory evidence that they are not non-residents,  the Trustee
may on behalf of such  Unitholders  sell such Units and, in the  interim,  shall
suspend the voting and  distribution  rights  attached  to such Units.  Any sale
shall be made on any stock exchange on which the Units are then listed and, upon
such sale,  the  affected  holders  shall cease to be holders of Units and their
rights shall be limited to receiving the net proceeds of sale upon  surrender of
the Certificates representing such Units.

3.9   Re-Purchase of Initial Unit by Trust

      Immediately after the closing of the Initial Offering, the Trust purchased
the Initial Unit from the Initial  Unitholder,  and the Initial  Unitholder sold
the  Initial  Unit to the Trust for a  purchase  price of  $100.00  and,  on the
completion of that  purchase and sale,  the Initial Unit was cancelled and is no
longer outstanding for any of the purposes of this Declaration of Trust.

3.10  Special Voting Units

      In  addition  to Units,  the Trust is hereby  empowered  to issue  Special
Voting Units having the rights and subject to the limitations,  restrictions and
conditions  set forth  herein.  The number of Special  Voting  Units that may be
issued shall be unlimited.

      Subject to the proviso that Special Voting Units may only be issued by the
Trust in conjunction with the issuance by the Corporation or an Affiliate of the
Corporation of  Exchangeable  Shares,  Special Voting Units may be issued at the
times,  to the persons,  for the  consideration  and on the terms and conditions
that the Corporation may determine.

      Each Special  Voting Unit shall  entitle the holder  thereof to attend and
vote at all meetings of  Unitholders.  The maximum  number of votes  attached to
each  Special  Voting  Unit  shall  be that  number  of  Units  into  which  the
Exchangeable  Shares issued in  conjunction  with the Special Voting Unit and at
that time outstanding are then  exchangeable.  Special Voting Units may be voted
by proxy on all matters that may

                                     - 13 -



properly come before the Unitholders of the Trust. Prior to delivering a Special
Voting Unit proxy,  the holder of a Special  Voting Unit shall be  obligated  to
determine,  in a manner  approved  by the  Corporation,  the manner in which the
holders  of the  then  outstanding  Exchangeable  Shares  that  were  issued  in
conjunction  with that Special  Voting Unit would vote on each matter put before
the  Unitholders.  The holder of the Special Voting Unit would then be obligated
to complete  the Special  Voting Unit proxy and record as votes in favour of the
matter  that  number  of votes  equal to the  number  of Units  into  which  the
Exchangeable  Shares  which voted in favour of the matter are then  exchangeable
and record as votes  against the matter that number of votes equal to the number
of Units into which the  Exchangeable  Shares which voted against the matter are
then exchangeable. Votes attached to the Special Voting Unit may only be counted
to the extent of the number of Units into which the  Exchangeable  Shares issued
in connection with the Special Voting Unit and then  outstanding have recorded a
vote on the matter.

      Special  Voting  Units shall have the rights  granted  above in respect of
voting at meetings of Unitholders and shall have no other rights in the Trust or
the Trust Fund and for greater certainty Special Voting Units do not represent a
beneficial interest in the Trust.

incidental thereto.

4.2   Short Term Investments

      Any funds  within the Trust Fund that are not  required  to be invested as

4.3   Other Investment Restrictions

      Without in any manner  qualifying or limiting the restrictions  imposed by
Sections  4.1 and 4.2,  under no  circumstances  shall  the  Trust  acquire  any

      (a)   would  result in the Units  becoming  "foreign  property" as defined
            under  the  provisions  of the  Income  Tax  Act at  the  time  such
            investment was acquired; or

      (b)   would result in the Trust not being considered either a "unit trust"
            or a "mutual  fund trust" for  purposes of the Income Tax Act at the
            time such investment was acquired.

                                    ARTICLE 5
                                  DISTRIBUTIONS

5.1   Distributions

      The  first  Distribution  Date of the Trust  shall be  January  15,  1997.
Commencing  January 15, 1997 the Trustee shall,  subject to Section 5.2, on each
Distribution Date cause the  Distributable  Income of the Trust to be determined
in respect of the immediately  preceding  Record Date and shall,  subject to any
limitations  contained in any Offering  Document,  distribute all  Distributable
Income to Unitholders  of record as at the close of business on the  immediately
preceding  Record Date in accordance  with the Pro Rata Share of each Unitholder
on that Record Date  (provided  that the Trustee may deduct or withhold  amounts
required by law from any Unitholder's distributions). Each Unitholder shall have
the right to enforce  the  payment of its share of  Distributable  Income on any
Distribution Date.

5.2   Change of Distribution Date

      The Trustee may change the Distribution Dates or any of them at any time
after October 15, 1997, subject to having given the Unitholders not less than 60
days' prior written notice, and may change the Record Date for any distribution
upon compliance with any requirements of applicable law or the rules of any
stock exchange.

5.3   Net Income for Income Tax Purposes to Become Payable

      On December 31 of each fiscal  year,  an amount equal to the net income of
the Trust for such fiscal year determined in accordance with the Income Tax Act,
other than  subsection  104(6)  thereof,  to the extent  not  otherwise  payable
pursuant  to  Section  5.1 on any  Record  Date in the  fiscal  year  (including
December  31 of that  fiscal  year) or deemed  to have  become  payable  for the
purposes of such Act  pursuant  to  subsection  104(29)  thereof,  shall  become
payable to  Unitholders  and a Unitholder  shall be entitled to

                                     - 15 -



enforce  payment thereof on that day. Each  Unitholder's  share thereof shall be
equal to the Pro Rata Share of such Unitholder.  Notwithstanding  the foregoing,
the amount of any  Distributable  Income of the Trust so determined for a fiscal
year that is  determined  by the  Trustee to be  required  to be retained by the
Trust in order to pay any tax  liability  of the Trust in respect of that or any
prior fiscal year shall not be payable by the Trust to Unitholders.

5.4   Payment of Amounts Payable

      Where any amount becomes  payable to a Unitholder  under Section 5.3, such
amount shall be paid to the Unitholder on the next  Distribution Date unless any
Unitholder  requests payment thereof prior to that  Distribution  Date, in which
case the  amount  shall be paid to each  Unitholder  to whom it  became  payable
forthwith.

5.5   Reinvestment of Distributions

      (a)   Subject to receipt of all regulatory approvals, the Trust shall make
            available to Unitholders the  opportunity to reinvest  distributions
            from  the  Trust  in  additional   Units  by   participating   in  a
            distribution  reinvestment  plan  (the  "Plan").  Upon a  Unitholder
            electing  to be  enrolled in the Plan,  all  distributions  from the
            Trust will  automatically be reinvested on such Unitholder's  behalf
            pursuant to the Plan until such Unitholder  terminates his enrolment
            in the Plan or the Trust terminates the Plan.

      (b)   Distributions  due to  participants  in the Plan will be paid to the
            Trustee in its  capacity as agent under the Plan (the "Plan  Agent")
            and be applied to the  purchase of Units.  The Plan Agent shall make
            such purchases from the Trust at a discount to the prevailing market
            price of 5%.

      (c)   The  Plan  Agent  shall  furnish  to  each  participant  after  each
            distribution a report of the Units  purchased for the  participant's
            account in respect of such  distribution and the cumulative total of
            all Units purchased for that account. The Trust shall pay out of the
            Trust Fund the Plan  Agent's  charges  for  administering  the Plan.
            Certificates  representing  Units  purchased  under the Plan will be
            issued only upon request of the Unitholder,  upon termination of the
            Unitholder's  participation  in the Plan or upon  termination of the
            Plan.  Distributions  on  fractional  Units will be credited to each
            participant's account. However, no certificates for fractional Units
            will be issued.  A cash adjustment for any fractional Units shall be
            paid to such  Unitholders,  when  necessary,  by cheque or, with the
            concurrence of the Plan Agent,  as such  Unitholder  shall otherwise
            direct.

      (d)   Unitholders may terminate their participation in the Plan by written
            notice to the Plan Agent. Such notice, if actually received prior to
            a Distribution  Date,  will be given effect to on that  Distribution
            Date.

                                     - 16 -



            Thereafter, distributions to such Unitholders will be by cheque. The
            Trust may terminate the Plan, in its sole discretion,  upon not less
            than 30 days' notice to the participants.

                                    ARTICLE 6
                               REDEMPTION OF UNITS

6.1   Right of Redemption

      Each  Unitholder  shall be  entitled to require the Trust to redeem at any
time or from time to time at the demand of the Unitholder all or any part of the
Units  registered  in the name of the  Unitholder at the prices  determined  and
payable in accordance with the conditions hereinafter provided.

6.2   Exercise of Redemption Right

      To exercise a Unitholder's  right to require redemption under this Article
6, a duly completed and properly  executed notice  requiring the Trust to redeem
Units,  in a form approved by the Trust,  shall be sent to the Trust at the head
office of the Trust, together with the Certificate or Certificates  representing
the Units to be redeemed.  No form or manner of completion or execution shall be
sufficient  unless the same is in all respects  satisfactory to the Trust and is
accompanied by any further  evidence that the Trust may reasonably  require with
respect to the identity, capacity or authority of the person giving such notice.

      Upon receipt by the Trust of the notice to redeem  Units,  the  Unitholder
shall thereafter cease to have any rights with respect to the Units tendered for
redemption (other than to receive the redemption payment therefor) including the
right to receive any  distributions  thereon  which are declared  payable to the
Unitholders  of record on a date which is  subsequent  to the date of receipt by
the  Trust  of such  notice.  Units  shall  be  considered  to be  tendered  for
redemption  on the date that the Trust has,  to the  satisfaction  of the Trust,
received the notice,  Certificates  and other required  documents or evidence as
aforesaid.

6.3   Cash Redemption

      Subject to Section 6.4,  upon receipt by the Trust of the notice to redeem
Units in  accordance  with  Section  6.2,  the holder of the Units  tendered for
redemption shall be entitled to receive a price per Unit (hereinafter called the
"Cash Redemption Price") equal to the lesser of:

      (a)   95% of the  market  price of the  Units on the  principal  market on
            which the Units are quoted  for  trading  during the 10 trading  day
            period

                                     - 17 -



            commencing  immediately  after  the date on  which  the  Units  were
            tendered to the Trust for redemption; and

      (b)   the closing market price on the principal  market on which the Units
            are quoted for trading,  on the date that the Units were so tendered
            for redemption.

      For  purposes of  subsection  6.3(a),  the market price shall be an amount
equal to the simple  average of the  closing  price of the Units for each of the
trading days on which there was a closing price; provided that if the applicable
exchange  or  market  does not  provide a closing  price but only  provides  the
highest and lowest  prices of the Units traded on a  particular  day, the market
price shall be an amount  equal to the simple  average of the highest and lowest
prices for that trading day if there was a trade;  and provided  further that if
there was  trading on the  applicable  exchange or market for fewer than five of
the ten  trading  days,  the market  price  shall be the  simple  average of the
following  prices  established  for each of the ten trading days: the average of
the bid and ask prices for each day on which there was no trading;  the weighted
average  trading  price of the Units for each day that there was  trading if the
exchange or market provides a weighted average trading price; and the average of
the highest and lowest  prices of the Units for each day that there was trading,
if the market  provides  only the highest and lowest prices of Units traded on a
particular  day. For purposes of  subsection  6.3(b),  the closing  market price
shall be an amount equal to the closing  price of the Units if there was a trade
on the date;  an amount equal to the average of the highest and lowest prices of
Units if there was trading and the  exchange or other market  provides  only the
highest and lowest  prices of Units traded on a particular  day; and the average
of the last bid and last ask prices if there was no trading on the date.

      The Cash  Redemption  Price  payable in respect of the Units  tendered for
redemption  during  any  month  shall be paid by  cheque,  drawn  on a  Canadian
chartered  bank or a trust company in lawful money of Canada,  payable at par to
or to the order of the  Unitholder  who exercised the right of redemption on the
last day of the  calendar  month  following  the month in which  the Units  were
tendered for redemption. Payments made by the Trust of the Cash Redemption Price
are  conclusively  deemed to have been  made upon the  mailing  of a cheque in a
postage prepaid envelope  addressed to the former  Unitholder unless such cheque
is  dishonoured  upon  presentment.  Upon  such  payment,  the  Trust  shall  be
discharged  from all liability to the former  Unitholder in respect of the Units
so redeemed.

6.4   No Cash Redemption in Certain Circumstances

      Section 6.3 shall not be applicable to Units  tendered for redemption by a
Unitholder, if:

      (a)   the total  amount  payable by the Trust  pursuant  to Section 6.3 in
            respect of such Units and all other Units tendered for redemption in
            the same

                                     - 18 -



            calendar month exceeds $100,000 provided that the board of directors
            of  the  Corporation  may,  in  its  sole  discretion,   waive  such
            limitation in respect of any calendar month;

      (b)   at the time the Units are tendered for  redemption,  the outstanding
            Units are not listed for trading on the Toronto  Stock  Exchange and
            are not traded or quoted on any other stock exchange or market which
            the board of directors of the Corporation  considers,  in their sole
            discretion, provides representative fair market value prices for the
            Units; or

      (c)   the normal trading of the  outstanding  Units is suspended or halted
            on any stock  exchange on which the Units are listed for trading or,
            if not so  listed,  on any  market on which the Units are quoted for
            trading,  on the date that such Units tendered for  redemption  were
            tendered to the Trust for  redemption  or for more than five trading
            days during the ten day trading period commencing  immediately after
            the date on which such Units tendered for  redemption  were tendered
            to the Trust for redemption.

6.5   In Specie Redemption

      If,  pursuant  to Section  6.4,  Section  6.3 is not  applicable  to Units
tendered for redemption by a Unitholder,  such Unitholder shall,  instead of the
Cash Redemption  Price per Unit specified in Section 6.3, be entitled to receive
a price per Unit (hereinafter  called the "In Specie Redemption Price") equal to
the fair market  value  thereof as  determined  by the board of directors of the
Corporation and in making such  determination  there shall be deducted from such
price otherwise determined the amount of the tax liability incurred by the Trust
as a result of such redemption (the "Redemption Tax  Liability").  The In Specie
Redemption Price shall, subject to all necessary regulatory  approvals,  be paid
and satisfied by way of a distribution  in specie of the assets of the Trust. No
fractional  securities of the Trust shall be distributed and where the number of
any securities of the Trust to be received upon redemption by a Unitholder would
otherwise  include a fraction,  that number  shall be rounded to the next lowest
whole  number.  The In Specie  Redemption  Price  payable  in  respect  of Units
tendered for redemption during any month shall be paid by the transfer, to or to
the order of the Unitholder  who exercised the right of redemption,  on the last
day (the "Transfer Date") of the calendar month following the month in which the
Units were tendered for  redemption,  of the assets of the Trust,  determined as
aforesaid. The Fund shall be entitled to all interest paid or accrued and unpaid
on any  securities of the Trust being  transferred,  and to all dividends on any
securities of the Trust being  transferred  which have been declared and paid or
have  been  declared  payable  on or before  the  Transfer  Date and to  similar
treatment in respect of  distributions  paid or payable and unpaid in respect of
any other  securities of the Trust being  transferred.  Payments by the Trust of
the In Specie  Redemption Price are  conclusively  deemed to have been made upon
the mailing of the assets of the Trust being transferred by registered mail in a

                                     - 19 -



postage prepaid envelope addressed to the former Unitholder.  Upon such payment,
the Trust shall be  discharged  from all  liability to the former  Unitholder in
respect of the Units so redeemed.

6.6   Cancellation of Certificates for all Redeemed Units

      All certificates  representing Units which are redeemed under this Article
6 shall be cancelled and such Units shall no longer be outstanding and shall not
be reissued.

6.7   Deemed Cancellation of Units Tendered into a Take-Over Bid

      Notwithstanding  any other  provisions of this Article 6, in the event any
person holding an option to purchase  Units granted  pursuant to an option plan,
compensation  arrangement or other similar arrangement  approved by the Trust or
Unitholders (as required by applicable law) exercises such option  following the
commencement  of a take-over bid (as defined in the  Securities  Act  (Alberta))
which is not exempt from the take-over bid  requirements  of the  Securities Act
(Alberta)  and the optionee  tenders the Units  received on the exercise of such
option  pursuant to the  take-over  bid, in the event any such Units so tendered
are not,  for any reason,  taken up and paid for by the Offeror  pursuant to the
take-over  bid then all such Units so  purchased  by the  optionee  shall be and
shall be deemed to be cancelled and returned to the Trust,  and the Trust,  upon
receiving a written  confirmation that all such Units have been transferred back
to the Trust,  shall refund to the optionee all consideration paid by him or her
in the initial  purchase of the Units,  excluding any commissions and other fees
paid in connection with such purchase.

                                    ARTICLE 7
               APPOINTMENT, RESIGNATION AND REMOVAL OF THE TRUSTEE

7.1   Trustee's Term of Office

      Subject to Sections 7.2 and 7.3,  Computershare Trust Company of Canada is
hereby  appointed as trustee under this Declaration of Trust for an initial term
of office which shall expire at the  conclusion  of the sixth annual  meeting of
Unitholders.  A decision to reappoint, or to appoint a successor to, the Trustee
shall be made at the sixth annual meeting of Unitholders  and thereafter at each
third  annual  meeting  of  Unitholders  following  the  meeting  at  which  any
reappointment  or  appointment is made.  Any such  reappointment  or appointment
shall be made either by an Ordinary Resolution at such meeting of Unitholders or
in the manner set out in Section  7.4.  Notwithstanding  the  foregoing,  if the
Trustee is not reappointed at the meeting of Unitholders held immediately before
the term of office of the Trustee  expires and if no successor to the Trustee is
appointed  at that  meeting,  the Trustee  shall  continue to hold the office of
trustee under this  Declaration  of Trust until a successor  has been  appointed
under Section 7.4.

                                     - 20 -



7.2   Resignation of Trustee

      The Trustee may resign from the office of trustee  hereunder on giving not
less than 60 days' notice in writing to the Corporation, but no such resignation
shall be effective until:

      (a)   a new trustee has been  appointed in the place of the Trustee in the
            manner set out in Section 7.4; and

      (b)   the new trustee has accepted  such  appointment  and has legally and
            validly assumed all obligations of the Trustee related hereto.

7.3   Removal of Trustee

      The  Trustee  shall be  removed  by notice  in  writing  delivered  by the
Corporation  to the Trustee in the event that, at any time, the Trustee shall no
longer  satisfy  all of the  requirements  of Section  7.6 or shall be  declared
bankrupt or insolvent or shall enter into  liquidation,  whether  compulsory  or
voluntary,  and not being  merely a voluntary  liquidation  for the  purposes of
amalgamation or reconstruction,  or if the assets of the Trustee shall otherwise
become  liable  to  seizure  or  confiscation  by  any  public  or  governmental
authority,  or if the Trustee shall otherwise  become incapable of performing or
shall fail in any material  respect to perform its  responsibilities  under this
Declaration of Trust, or as a result of a material  increase in the fees charged
by the Trustee.

      No notice to remove  the  Trustee  under  this  Section  7.3 shall  become
effective until:

      (a)   the  removal  of  the  Trustee  has  been  approved  by an  Ordinary
            Resolution at a meeting of Unitholders duly called for that purpose;

      (b)   a new trustee has been  appointed in the place of the Trustee in the
            manner set out in Section 7.4; and

      (c)   the new trustee has accepted  such  appointment  and has legally and
            validly assumed all obligations of the Trustee related hereto.

7.4   Appointment of Successor to Trustee

      A successor to a Trustee which has been removed under Section 7.3 or which
has given  notice of  resignation  under  Section 7.2 shall be  appointed  by an
Ordinary  Resolution  passed at a meeting of  Unitholders  duly  called for that
purpose, provided the successor meets the requirements of Section 7.6.

      Subject to Section  7.6,  the  Corporation  may appoint a successor to any
Trustee which has been removed  under  Section 7.3,  which has given a notice of
resignation

                                     - 21 -



under Section 7.2, or which has not been  reappointed  under Section 7.1, if the
Unitholders fail to do so at the relevant meeting.

      No  appointment  of any successor  trustee  shall be effective  until such
successor  trustee has  accepted  such  appointment  and has legally and validly
assumed all of the obligations of the Trustee related hereto.

7.5   Failure to Appoint Successor

      In the event that no successor to a Trustee  which has  delivered a notice
of  resignation in accordance  with Section 7.2 or which has received  notice of
removal in  accordance  with Section 7.3 has accepted an  appointment  within 60
days after the receipt by the  Corporation  of the notice of  resignation  or 60
days after the receipt by the Trustee of the notice of removal, the Trustee, the
Corporation or any Unitholder may apply to a court of competent jurisdiction for
the appointment of a successor to the Trustee. The appointment of such successor
by such court shall not require the approval of Unitholders.

7.6   Qualifications of Trustee

      The Trustee and any successor to the Trustee or any new trustee  appointed
under  this  Article  7 shall be a  corporation  incorporated  under the laws of
Canada or of a  province  thereof  and  shall be a  resident  of Canada  for the
purposes of the Income Tax Act.  Such  corporation  must at all times when it is
the Trustee be registered  under the laws of the Province of Alberta to carry on
the  business  of a trust  corporation  and must have  undertaken  in writing to
discharge all of the obligations and  responsibilities of the Trustee under this

shall be a corporation which has reported in its audited consolidated  financial
statements for its most recent completed fiscal year shareholders'  equity of at
least $100 million or such other amount as the Board of Directors  shall approve
or be an Affiliate of such a corporation,  provided that all of the  obligations
of such Affiliate are unconditionally guaranteed by such a corporation.

behalf by such one or more  officers of the Trustee or other Persons (who may be
officers or employees of the Corporation) as the Trustee may designate,  appoint

8.4   Standard of Care

      Except as otherwise  provided  herein,  the Trustee  shall comply with any

and shall  exercise its powers and carry out its functions  hereunder as trustee
honestly,  in  good  faith  and in the  best  interests  of the  Trust  and  the
Unitholders  and, in connection  therewith,  shall exercise that degree of care,
diligence and skill that a reasonably

                                     - 26 -



prudent  trustee would exercise in comparable  circumstances.  Unless  otherwise
required  by law,  the Trustee  shall not be  required  to give bond,  surety or
security in any  jurisdiction  for the  performance of any duties or obligations
hereunder.  The Trustee,  in its  capacity as trustee,  shall not be required to
devote its entire time to the affairs of the Trust.

8.5   Fees and Expenses

      The Trustee  shall be paid by the  Corporation  such fees as may be agreed
upon in writing from time to time by the Corporation and the Trustee, and if any
such  fees are not  paid by the  Corporation  within  30 days of the date of any

charges and expenses are not paid by the Corporation  within 30 days of the date
of any invoice in respect  thereof,  the Trustee  shall be entitled to have such
costs, charges and expenses paid out of the Trust Fund. The Trustee shall have a
lien on the Trust Fund (which  shall have  priority  over the  interests  of the
Unitholders pursuant hereto) to enforce payment of the fees, costs, expenses and
other amounts payable or reimbursable by the Trust to the Trustee.

8.6   Limitations on Liability of Trustee

      The Trustee, its directors,  officers, employees,  shareholders and agents
shall not be liable to any Unitholder or any other Person, in tort,  contract or
otherwise,  in connection  with any matter  pertaining to the Trust or the Trust
Fund,  arising  from the exercise by the Trustee of any powers,  authorities  or
discretion  conferred  under  this  Declaration  of  Trust,  including,  without
limitation,  any  action  taken or not taken in good  faith in  reliance  on any
documents that are, prima facie, properly executed, any depreciation of, or loss
to, the Trust Fund incurred by reason of the sale of any asset,  any  inaccuracy
in any  evaluation  provided  by the  Corporation  or  any  other  appropriately
qualified Person, any reliance on any such evaluation,  any action or failure to
act of the  Corporation  or any other Person to whom the Trustee  has,  with the
consent of the Corporation,  delegated any of its duties hereunder, or any other
action or  failure  to act  (including  failure  to compel in any way any former
trustee to  redress  any breach of trust or any  failure by the  Corporation  to
perform its duties under or delegated to it under this  Declaration  of Trust or
any Material  Contract),  unless such liabilities  arise out of the Trustee's or
any such  director's,  officer's,  employee's,  shareholder's  or agent's  gross
negligence, wilful default or fraud. If the Trustee has

                                     - 27 -



retained an appropriate  expert or adviser or Counsel with respect to any matter
connected  with its  duties  under  this  Declaration  of Trust or any  Material
Contract,  the  Trustee  may act or refuse  to act  based on the  advice of such
expert, adviser or Counsel, and the Trustee shall not be liable for and shall be
fully  protected from any loss or liability  occasioned by any action or refusal
to act based on the  advice  of any such  expert,  adviser  or  Counsel.  In the
exercise of the powers,  authorities  or discretion  conferred  upon the Trustee
under this Declaration of Trust, the Trustee is and shall be conclusively deemed
to be acting as  trustee  of the assets of the Trust and shall not be subject to
any personal liability for any debts, liabilities, obligations, claims, demands,
judgments,  costs,  charges or expenses  against or with respect to the Trust or
the Trust Fund.

employees,  shareholders  and agents  and all of their  successors  and  assigns
(collectively, the "Indemnified Parties") in respect of:

      (a)   any  liability  and all costs,  charges and  expenses  sustained  or
            incurred  in  respect  of any  action,  suit or  proceeding  that is
            proposed or commenced against any Indemnified Party, as the case may
            be, for or in respect  of any act,  omission  or error in respect of
            the  Trust  and  the   Trustee's   execution   of  all   duties  and
            responsibilities   and  exercise  of  all  powers  and   authorities
            pertaining thereto; and

      (b)   all other costs, charges,  taxes,  penalties and interest in respect
            of unpaid taxes and all other expenses and liabilities  sustained or
            incurred  by  the  Trustee  in  respect  of  the  administration  or
            termination of the Trust;

unless  any of  the  foregoing  arises  out of  the  Indemnified  Party's  gross
negligence,  wilful  default  or fraud,  in which  case the  provisions  of this
Section 8.7 shall not apply.

8.8   Environmental Indemnity

      The Trust  (to the  extent of the  Trust  Fund) is  liable  to,  and shall
indemnify and save harmless,  the Indemnified Parties against any loss, expense,
claim, liability or asserted liability (including strict liability and costs and
expenses of abatement and remediation of spills or releases of contaminants  and
liabilities of the Indemnified Parties to third parties (including  governmental
agencies)  in  respect  of  bodily  injuries,  property  damage,  damage  to  or
impairment  of the  environment  or any other  injury or  damage  and  including
liabilities of the  Indemnified  Parties to third parties for the third parties'
foreseeable and unforeseeable consequential damages) incurred as a result of:

      (a)   the administration of the Trust created hereby; or

                                     - 28 -

            obligations hereunder or under any of the Material Contracts;

      (c)   the  presence  or release or  threatened  presence or release of any
            contaminants,  by any means or for any  reason,  on or in respect of
            the  Properties,   whether  or  not  such  presence  or  release  or
            threatened  presence  or release of the  contaminants  was under the
            control, care or management of the Trust or the Corporation, or of a
            previous owner or operator of a Property;

      (d)   any contaminant present on or released from any property adjacent to
            or in the proximate area of the Properties;

            environmental law, regulation,  by-law, order, rule or permit by the
            Trust or the Corporation or an owner or operator of a Property; or

      (f)   any  misrepresentation or omission of a known fact or condition made
            by the Corporation relating to any Property.

            For purposes of this Section 8.8, "liability" shall include:

            (i)   liability  of an  Indemnified  Party for costs and expenses of
                  abatement   and   remediation   of  spills  and   releases  of
                  contaminants;

            (ii)  liability  of  an  Indemnified  Party  to  a  third  party  to
                  reimburse the third party for bodily injuries, property damage
                  and other  injuries or damages which the third party  suffers,
                  including (to the extent,  if any, that the Indemnified  Party
                  is   liable    therefor)    foreseeable   and    unforeseeable
                  consequential damages suffered by the third party; and

            (iii) liability of the Indemnified Party for damage to or impairment
                  of the environment.

      Notwithstanding the foregoing,  the Trust shall not be liable to indemnify
an Indemnified  Party against any loss,  expense,  claim,  liability or asserted
liability to the extent such results from the gross  negligence,  wilful default
or fraud of the Indemnified Party.

8.9   Apparent Authority

      No Person dealing with the Trustee or with any officer,  employee or agent
of the Trustee shall be bound to make any inquiry concerning the validity of any
transaction

                                     - 29 -



purported to be made by the Trustee or by such officer,  employee or agent or to
make any inquiry  concerning,  or be liable  for,  the  application  of money or
property  paid,  lent or  delivered to or on the order of the Trustee or of such
officer,  employee or agent.  Any Person  dealing with the Trustee in respect of
any matter pertaining to the Trust Fund and any right, title or interest therein
shall be entitled to rely on a certificate,  statutory declaration or resolution
executed or  certified  on behalf of the Trustee as to the  capacity,  power and
authority of any officer,  employee or any other Person to act for and on behalf
and in the name of the Trust.

8.10  Notice to Unitholders of Non-Eligibility for Deferred Income Plans

      If the Trustee  becomes  aware that the Units have ceased to be  qualified
investments  for  registered  retirement  savings plans,  registered  retirement
income funds and deferred  profit  sharing  plans (all within the meaning of the
Income  Tax  Act) or any of  such  plans,  the  Trustee  shall  give  notice  to
Unitholders at their latest address as shown on the register of Unitholders that
Units have ceased to be qualified  investments for such plans. The Trustee shall
not be  liable  to the  Trust  or to any  Unitholder  for any  costs,  expenses,
charges,  penalties  or taxes  imposed  upon a  Unitholder  as a result of or by
virtue  of  a  Unit  not  being  a  qualified  investment  for  any  such  plan,
notwithstanding  any  failure  or  omission  of the  Trustee  to have given such
notice, provided the Trustee has complied with Section 8.4.

8.11  Declaration as to Beneficial Owner

      The  Trustee  may  require  any  Unitholder  as shown on the  register  of
Unitholders to provide a declaration,  in form prescribed by the Trustee,  as to

      The  obligation of the Trustee to call any meeting  pursuant to Article 11
or to commence to wind up the affairs of the Trust  pursuant to Article 15 shall
be conditional upon the Corporation,  Unitholders or any other Person furnishing
sufficient  funds to commence or continue  such act,  action or  proceeding  and
furnishing an indemnity (to the extent sufficient funds for such purpose are not
available in the Trust Fund)  reasonably  satisfactory to the Trustee to protect
and  hold  harmless  the  Trustee  against  the  costs,  charges,  expenses  and
liabilities  to be  incurred  thereby  and any loss and  damage it may suffer by
reason  thereof,  and the  obligation of the Trustee to commence or continue any
other act,  action or proceeding  for the purpose of performing its duties under
this  Declaration  of Trust or  enforcing  the rights of the  Trustee and of the
Unitholders  shall, if required by notice in writing by the Trustee,  be subject
to the same  conditions  as to funding  and  indemnity.  None of the  provisions
contained in this  Declaration  of Trust shall  require the Trustee to expend or
risk its own funds or

                                     - 30 -



otherwise incur  financial  liability in the performance of any of its duties or
in the  exercise  of any of its  rights or powers  unless it is  indemnified  as
aforesaid.

8.13  Survival of Indemnities

      The  indemnities  provided  in  Sections  8.7 and 8.8  shall  survive  the
termination  of this  Declaration  of Trust under  Article 15 and the removal or
resignation of the Trustee under Article 7.

8.14  Trustee May Have Other Interests

      Subject  to  applicable  securities  laws  and the  qualifications  of the
Trustee  provided in Section 7.6,  and without  affecting or limiting the duties

            of the Trust have been or are to be purchased or sold;

      (b)   be, or be an Associate  or an  Affiliate  of, a Person with whom the

            services to the Trust or the Corporation;

      (c)   acquire,  hold and  dispose  of,  either for its own  account or the
            accounts of its customers,  any assets not constituting  part of the
            Trust Fund,  even if such  assets are of a character  which could be
            held by the  Trust,  and  exercise  all  rights  of an owner of such
            assets as if it were not a trustee;

      (d)   carry on its  business as a trust  company in the usual course while
            it is the  Trustee,  including  the  rendering  of  trustee or other

            stated in this Section 8.14 without being liable to the Trust or any
            Unitholder  for any such  direct  or  indirect  benefit,  profit  or
            advantage.

Subject to  applicable  laws,  none of the  relationships,  matters,  contracts,
transactions, affiliations or other interests permitted above shall be, or shall
be deemed to be or to create, a material conflict of interest with the Trustee's
duties hereunder.

time be held by the  Trustee  subject to the trusts  hereof may be placed in the

      Except as otherwise provided herein or as expressly prohibited by law, the
Trustee may grant or delegate to the  Corporation  such authority as the Trustee
may in its sole  discretion  deem  necessary  or  desirable to effect the actual
administration  of the duties of the Trustee  under this  Declaration  of Trust,

for the Trust, to execute documents on behalf of the Trust and to make decisions
which  conform to general  policies and general  principles  set forth herein or
established  by the Trustee.  The  Corporation  shall have the powers and duties
expressly  provided for herein and in the  Management  Agreement,  including the
power to further delegate  administration of the Trust, provided that no further
delegation  shall be effective  until the  Corporation  shall have  notified the
Trustee of the name of the Person or Persons to whom such further  delegation is
made and the terms and conditions thereof. The Trustee may enter into a contract
with  the  Corporation  relating  to  the  Corporation's   authority,   term  of
appointment, compensation and any other matters deemed desirable by the Trustee.

            accuracy of the disclosure  contained therein, and the certification
            thereof;

      (c)   all matters concerning the terms of the Material Contracts; and

      (d)   all matters concerning any Underwriting  Agreement providing for the
            sale of Units or rights to Units.

The  Corporation  accepts such  delegation  and agrees that,  in respect of such
matters,  it shall carry out its  functions  honestly,  in good faith and in the
best interests of the Trust and the  Unitholders  and, in connection  therewith,
shall  exercise  that  degree of care,  diligence  and skill  that a  reasonably
prudent Person would exercise in comparable circumstances.  The Corporation may,
and if directed by the  Corporation  in writing the Trustee  shall,  execute any
agreements  on behalf  of the Trust as the  Corporation  shall  have  authorized
within the scope of any authority delegated to it hereunder.

                                     - 33 -



9.3   Power of Attorney

      Without  limiting  any of the  other  provisions  of this  Article  9, the
Trustee hereby  irrevocably  delegates to the Corporation  from time to time the
full power and authority,  and irrevocably  constitutes the Corporation its true
and lawful  attorney in fact,  to sign on behalf of the Trust all  prospectuses,
annual information forms,  management proxy circulars,  other Offering Documents
and any  other  documents  ancillary  or  similar  thereto  or to  complete  the
transactions  contemplated  thereby  that are required to be signed by the Trust
from time to time.

9.4   Liability of Trustee

      The Trustee  shall have no  liability  or  responsibility  for any matters
delegated to the Corporation  hereunder or under any of the Material  Contracts,
and the  Trustee,  in relying  upon the  Corporation  and in  entering  into the
Material Contracts,  shall be deemed to have complied with its obligations under
Section 8.4 and shall be entitled  to the benefit of the  indemnity  provided in
Sections 8.7 and 8.8.

9.5   Performance of Obligations

      In the event that the  Corporation  is unable or  unwilling to perform its
obligations under the Management Agreement, the Trustee shall either perform all
obligations of the Corporation thereunder or shall be entitled to engage another
Person that is duly qualified to perform such obligations.

Declaration  of Trust may only be amended by the Trustee with the consent of the
Unitholders  by  Special  Resolution;  provided  that  the  provisions  of  this
Declaration of Trust and the Material Contracts may be amended by the Trustee at
any time or times,  without the consent,  approval or ratification of any of the
Unitholders:

      (a)   prior to closing the Initial Offering; or

      (b)   at any time for the purpose of:

            (i)   ensuring that the Trust will comply with any  applicable  laws
                  or  requirements  of any  governmental  agency or authority of
                  Canada or of any province;

                                     - 34 -



            (ii)  ensuring that the Trust will satisfy the provisions of each of
                  sections  108(2)(b)  and 132(6) of the Income Tax Act, as from
                  time to time amended or replaced;

            (iii) ensuring that such  additional  protection is provided for the
                  interests   of   Unitholders   as  the  Trustee  may  consider
                  expedient;

            (iv)  removing or curing any  conflicts or  inconsistencies  between
                  the provisions of this  Declaration of Trust, any supplemental
                  indenture or the Royalty  Agreement and any other agreement of
                  the Trust, any Offering Document with respect to the Trust, or
                  any applicable law or regulation of any jurisdiction, provided
                  that in the  opinion of the  Trustee the rights of the Trustee
                  and of the Unitholders are not materially  prejudiced thereby;
                  and

            (v)   curing, correcting or rectifying any ambiguities, defective or
                  inconsistent   provisions,   errors,  mistakes  or  omissions,
                  provided  that in the opinion of the Trustee the rights of the
                  Trustee and of the Unitholders  are not materially  prejudiced
                  thereby.

      Notwithstanding the foregoing, no amendment shall reduce the percentage of
votes  required  to be cast at a meeting of the  Unitholders  for the purpose of
amending  this  Section  10.1  without  the consent of the holders of all of the
Units then Outstanding.

10.2  Notification of Amendment

      As soon as shall be practicable after the making of any amendment pursuant
to this  Article 10, the  Trustee  shall  furnish  written  notification  of the
substance of such amendment to each Unitholder.

                                   ARTICLE 11
                             MEETINGS OF UNITHOLDERS

11.1  Meetings of Unitholders

      Annual  meetings  of the  Unitholders  shall  be  called  by the  Trustee,
commencing in 1997, on a day, at a time and at a place to be set by the Trustee.
The business  transacted at such meetings shall include the  transaction of such
business as Unitholders may be entitled to vote upon as provided in this Article
11, or as the Trustee may determine.  Special meetings of the Unitholders may be
called at any time by the Trustee  and shall be called by the  Trustee  upon the
written request of Unitholders holding in the aggregate not less than 20% of the
Units then  Outstanding,  such  request  specifying  the purpose or purposes for
which such meeting is to be called. Meetings of Unitholders shall be held in the
City of  Calgary,  or at such other place as

                                     - 35 -



the Trustee shall designate. The chairman of any annual or special meeting shall
be a Person  designated  by the Trustee for the purpose of such  meeting  except
that, on the motion of any Unitholder,  any Person may be elected as chairman by
a majority of the votes cast at the meeting instead of such designated Person or
in the event that no Person shall be designated by the Trustee.

11.2  Notice of Meetings

      Notice of all meetings of Unitholders  shall be given by unregistered mail
postage prepaid addressed to each Unitholder at his registered  address,  mailed
at least 21 days and not more than 50 days before the meeting. Such notice shall
set out the time when, and the place where, such meeting is to be held and shall
specify  the  nature  of the  business  to be  transacted  at  such  meeting  in
sufficient  detail to permit a Unitholder to form a reasoned  judgment  thereon,
together  with the text of any special  resolution in  substantially  final form
proposed to be passed.  Any adjourned  meeting may be held as adjourned  without
further notice. The accidental  omission to give notice to or the non-receipt of
such notice by the Unitholders shall not invalidate any resolution passed at any
such meeting.

11.3  Quorum

      At any meeting of Unitholders,  subject as hereinafter  provided, a quorum
shall consist of two Persons  either  present in person or  represented by proxy
and representing in the aggregate not less than 5% of the Outstanding  Units. If
a quorum is not present at the appointed place on the date for which the meeting
is called  within  one-half  hour after the time  fixed for the  holding of such
meeting,  the meeting,  if convened on the requisition of Unitholders,  shall be
dissolved,  but in any other case it shall stand adjourned to such day being not
less than 14 days  later and to such place and time as may be  appointed  by the
chairman of the meeting.  If at such adjourned meeting a quorum as above defined
is not present,  the  Unitholders  present  either  personally or by proxy shall
constitute a quorum,  and any  business  may be brought  before or dealt with at
such an adjourned  meeting which might have been brought before or dealt with at
the original meeting in accordance with the notice calling the same.

11.4  Voting Rights of Unitholders

      Only  Unitholders  of record shall be entitled to vote and each Unit shall
entitle  the  holder  or  holders  of that  Unit to one vote at any  meeting  of
Unitholders. At any meeting of Unitholders, any holder of Units entitled to vote
thereat may vote by proxy and a proxy need not be a Unitholder, provided that no
proxy  shall be voted at any  meeting  unless it shall have been  placed on file
with the  Trustee,  or with such agent of the Trustee as the Trustee may direct,
for verification at least 24 hours prior to the commencement of such meeting. If
approved by the  Trustee,  proxies may be  solicited in the name of the Trustee.
When any Unit is held  jointly by several  Persons,  any one of

                                     - 36 -



them may vote at any meeting in person or by proxy in respect of such Unit,  but
if more than one of them shall be present at such meeting in person or by proxy,
and such joint owners or their proxies so present  disagree as to any vote to be
cast,  the joint owner  present or  represented  whose name appears first in the
register  maintained  pursuant  to Section  12.5 shall be  entitled to cast such
vote.

11.5  Actions Requiring Ordinary Resolutions

            specified  in Section  10.1 and Section  16.1  (other  than  Section
            16.1(a));

            estimated  pre-tax net cash flow from all of the proved reserves and
            50% of the estimated  pre-tax net cash flow from all of the probable
            reserves of the Corporation,  the Trust and their subsidiaries taken
            as a whole as shown in the most recent  engineering  report relating
            to such reserves;

                                     - 37 -

            entirety.

      Except  with  respect  to the  matters  set out in  Section  11.5 and this
Section  11.6,  no action  taken by the  Unitholders  and no  resolution  of the
Unitholders  at any meeting shall in any way bind the Trustee.  Any action taken
or resolution  passed in respect of any matter at a meeting of Unitholders shall
be by Special  Resolution  unless the contrary is otherwise  expressly  provided
under any specific provision of this Declaration of Trust.

11.7  Meaning of "Special Resolution"

      The  expression  "Special  Resolution"  means a resolution  proposed to be
passed as a  special  resolution  at a  meeting  of  Unitholders  (including  an
adjourned meeting) duly convened for the purpose and held in accordance with the
provisions of this Declaration of Trust at which two or more holders of at least
5% of the aggregate  number of Units then  Outstanding  are present in person or
represented by proxy and passed by the  affirmative  votes of the holders of not
less than 66% of the Units  represented  at the meeting and voted on a poll upon
such resolution.

      Notwithstanding  Section 11.3, if, at any such meeting,  the holders of 5%
of the  aggregate  number  of Units  Outstanding  are not  present  in person or
represented  by proxy  within  one-half  hour after the time  appointed  for the
meeting,  then the meeting, if convened by or on the requisition of Unitholders,
shall be dissolved; but in any other case it shall stand adjourned to such date,
being not less than 21 nor more than 60 days  later,  and to such place and time
as may be appointed by the chairman.  Not less than ten days' prior notice shall
be given of the time and place of such adjourned  meeting in the manner provided
in Section  11.2.  Such  notice  shall state that at the  adjourned  meeting the
Unitholders present in person or represented by proxy shall form a quorum but it
shall not be  necessary  to set forth the  purposes  for which the  meeting  was
originally  called or any  other  particulars.  At the  adjourned  meeting,  the
Unitholders  present in person or represented by proxy shall constitute a quorum
and may transact the business for which the meeting was originally convened, and
a resolution proposed at such adjourned meeting and passed by the requisite vote
as  provided  in this  Section  11.7  shall be a Special  Resolution  within the
meaning of this Declaration of Trust,  notwithstanding  that the holders of less
than 5% of the aggregate  number of Units then outstanding are present in person
or represented by proxy at such adjourned meeting.

                                     - 38 -



      Votes on any  Special  Resolution  shall  always be given on a poll and no
demand  for a poll on any  Special  Resolution  shall be  necessary.  No Special
Resolution changing or amending any provision hereof relating to or affecting:

      (a)   the  Trustee,  including  the  qualification,  powers,  authorities,
            appointment, removal or resignation thereof;

      (b)   the Royalty Agreement; or

      (c)   the provisions of Article 10, Article 11 or Article 15;

shall be effective prior to 60 days from the adoption thereof in accordance with
the provisions hereof.

11.8  Record Date for Voting

      For the purpose of determining the Unitholders who are entitled to receive
notice of and vote or act at any meeting or any adjournment thereof, the Trustee
may fix a date not more than 50 days and not less than 21 days prior to the date
of any  meeting  of  Unitholders  as a  record  date  for the  determination  of
Unitholders  entitled  to  receive  notice  of and vote at such  meeting  or any
adjournment  thereof,  and any  Unitholder  who was a Unitholder  at the time so
fixed  shall be entitled  to receive  notice of and vote at such  meeting or any
adjournment  thereof  even though he has since that time  disposed of his Units,
and no  Unitholder  becoming  such after that time shall be  entitled to receive
notice of or vote at such meeting or any adjournment  thereof. In the event that
the  Trustee  does not fix a record  date for any  meeting of  Unitholders,  the
record date for such meeting shall be the Business Day immediately preceding the
date upon which notice of the meeting is given as provided under Section 11.2.

11.9  Binding Effect of Resolutions

      Every  Ordinary   Resolution  and  every  Special   Resolution  passed  in
accordance  with the  provisions  of this  Declaration  of Trust at a meeting of
Unitholders  shall be binding upon all the  Unitholders,  whether  present at or
absent  from such  meeting,  and each  Unitholder  shall be bound to give effect
accordingly to every such Ordinary Resolution and Special Resolution.

11.10 Appointment of Inspector

      The Trustee shall call a meeting of Unitholders  upon the written  request
of  Unitholders  holding  in the  aggregate  not less than 20% of the Units then
outstanding  for the purpose of considering  the  appointment of an inspector to
investigate the performance by the Trustee of any of its  responsibilities.  The
inspector shall have such powers not  inconsistent  herewith as may be conferred
upon him at the meeting when

                                     - 39 -



he is  appointed,  but in all  events  shall  not have any  powers to act in any
capacity as the Trustee  hereunder or in place or in stead of the Trustee in any
manner hereunder.

11.11 Solicitation of Proxies

      A Unitholder shall have the right to appoint a proxy to attend and act for
the Unitholder at any meeting of Unitholders.  The Trustee shall solicit proxies
from  Unitholders in connection with all meetings of Unitholders.  In connection
therewith, the Trustee shall comply, to the extent possible, with all provisions
of the Business  Corporations  Act  (Alberta) and the  requirements  of Canadian
securities legislation applicable to the solicitation of proxies.

11.12 No Breach

      Notwithstanding  any provision of this  Declaration of Trust,  Unitholders
shall have no power to effect any  amendment  hereto  which  would  require  the
Trustee to take any action or conduct the affairs of the Trust in a manner which
would  constitute  a breach or  default  by the Trust or the  Trustee  under any
agreement binding on or obligation of the Trust or the Trustee.

            prescribe.

      In the event that any provision of the Certificates in the French language

            to any act performed by the Trustee or by any other person  pursuant
            to the  Declaration  of Trust,  and all persons shall look solely to
            the  assets of the Trust for  satisfaction  of claims of any  nature
            arising  out of or in  connection  therewith  and the  assets of the
            Trust only shall be subject to levy or  execution"  or words of like
            effect.

                                     - 41 -



The Certificates may be engraved, printed or lithographed, or partly in one form
and partly in another, as the Trustee may determine.

12.4  Signing of Certificates

      Each  Certificate  shall bear an  identifying  serial  number and shall be
signed by the Corporation on behalf of the Trust and shall be countersigned  and
registered  by  the  Transfer  Agent.  Any  signature  by or on  behalf  of  the
Corporation appearing on a Certificate may be printed, lithographed or otherwise
mechanically reproduced thereon, and any Certificate so signed shall be as valid
as if it had been signed manually. Any Certificate so signed,  countersigned and
registered shall be valid  notwithstanding that one or more of the Persons whose
signature is printed,  lithographed or  mechanically  reproduced no longer holds
office  at the  date  of  issuance  of  such  Certificate.  Certificates  may be
engraved, printed or lithographed,  or partly in one form and partly in another,
as the Trustee may determine.

12.5  Register of Unitholders

      A register shall be maintained at the principal  corporate trust office of
the Transfer  Agent in the City of Calgary,  which  register  shall  contain the
names and addresses of the Unitholders,  the respective numbers of Units held by
them, the numbers of the Certificates  representing  such Units, and a record of
all transfers thereof. Branch transfer registers shall be maintained in the City
of Toronto and at such other  offices of the  Transfer  Agent as the Trustee may
from time to time designate.  Except in the case of the register  required to be
maintained at the City of Calgary,  the Trustee shall have the power at any time
to close any register of transfers and in that event shall  transfer the records
thereof to another existing register or to a new register.

      Only  Unitholders  whose  Units  are  recorded  in the  register  shall be
entitled  to  receive  distributions  or to  exercise  or enjoy  the  rights  of
Unitholders  hereunder.  The  Trustee  shall have the right to treat the Persons
registered  as  Unitholders  on the  register of the Trust as the owners of such
Units  for  all  purposes,   including,  without  limitation,   payment  of  any
distribution,  giving notice to Unitholders  and determining the right to attend
and vote at  meetings  of  Unitholders,  and the  Trustee  shall not be bound to
recognize any transfer,  pledge or other disposition of a Unit or any attempt to
transfer,  pledge or dispose of a Unit, or any beneficial  interest or equitable
or other right or claim with respect  thereto,  whether or not the Trustee shall
have actual or other notice thereof, until such Unit shall have been transferred
on the register of the Trust as herein provided.

      The register  and branch  transfer  registers  referred to in this Section
12.5 shall at all reasonable  times be open for  inspection by the  Unitholders,
the Corporation and the Trustee.

                                     - 42 -



12.6  Transfer of Units

      Subject to the  provisions  of this  Article  12, the Units shall be fully
transferable  without charge as between Persons,  but no transfer of Units shall
be  effective  as against the  Trustee or shall be in any way  binding  upon the
Trustee  until the  transfer  has been  recorded  on the  register or one of the
branch  transfer  registers  maintained by the Transfer  Agent. No transfer of a
Unit shall be recognized unless such transfer is of a whole number of Units.

      Subject to the provisions of this Article 12, Units shall be  transferable
on the register or one of the branch transfer  registers only by the Unitholders
of  record   thereof  or  their   executors,   administrators   or  other  legal
representatives  or by their agents duly  authorized  in writing,  and only upon
delivery to the Trustee or to the Transfer  Agent of the  Certificate  therefor,
properly  endorsed or accompanied by a duly executed  instrument of transfer and
accompanied  by all necessary  transfer or other taxes imposed by law,  together
with  such  evidence  of the  genuineness  of such  endorsement,  execution  and
authorization  and other  matters as may  reasonably be required by the Trustee.
Upon such delivery the transfer shall be recorded on the register of Unitholders
and a new  Certificate  for the residue  thereof (if any) shall be issued to the
transferor.

      Any Person  becoming  entitled to any Units as a consequence of the death,
bankruptcy or  incompetence  of any  Unitholder or otherwise by operation of law
shall  be  recorded  as the  holder  of  such  Units  and  shall  receive  a new
Certificate  therefor  only upon  production  of  evidence  satisfactory  to the
Trustee  thereof and delivery of the existing  Certificate  to the Trustee,  and
until such record is made the  Unitholder of record shall  continue to be and be
deemed  to be the  holder  of such  Units for all  purposes  whether  or not the
Trustee shall have actual or other notice of such death or other event.

12.7  Units Held Jointly or in a Fiduciary Capacity

      The  Trustee  may treat  two or more  Persons  holding  any Units as joint
owners of the entire  interest  therein  unless  their  ownership  is  expressly
otherwise  recorded on the register of the Trust,  but no entry shall be made in
the  register  or on any  Certificate  that any  Person is in any  other  manner
entitled to any future,  limited or contingent interest in any Units;  provided,
however, that any Person recorded as a Unitholder may, subject to the provisions
hereinafter  contained,  be described in the register or on any Certificate as a
fiduciary of any kind and any customary words may be added to the description of
the  holder to  identify  the  nature  of such  fiduciary  relationship.  If any
Certificate  is registered in more than one name, the  distributions  in respect
thereof may be paid to the order of all such holders failing written instruction
from them to the contrary,  and such payment  shall be a valid  discharge to the
Trustee and any  Transfer  Agent.  In the case of the death of one of more joint
holders,  the  distributions in respect of any Units

                                     - 43 -



may be paid to the survivor or survivors of such holders, and such payment shall
be a valid discharge to the Trustee and any Transfer Agent.

12.8  Performance of Trust

      The Trustee, the Unitholders and any director,  officer, employee or agent
of the Trustee  shall not be bound to be  responsible  for or otherwise  inquire
into or ensure the performance of any trust,  express,  implied or constructive,
or of any  charge,  pledge or  equity to which any of the Units or any  interest
therein are or may be subject,  or to ascertain or enquire  whether any transfer
of any such Units or interests therein by any such Unitholder or by his personal
representatives  is authorized by such trust,  charge,  pledge or equity,  or to
recognize  any  Person as having  any  interest  therein  except  for the Person
recorded as a Unitholder.

12.9  Lost Certificates

      In the event that any Certificate is lost, stolen, destroyed or mutilated,
the Trustee may authorize the issuance of a new  Certificate for the same number
of Units in lieu thereof. The Trustee may in its discretion, before the issuance
of such new  Certificate,  require the owner of the lost,  stolen,  destroyed or
mutilated  Certificate,  or the legal  representative  of the owner,  to make an
affidavit  or  statutory  declaration  setting  forth such facts as to the loss,
theft, destruction or mutilation as the Trustee may deem necessary, to surrender
any  mutilated  Certificate,  and to supply to the  Trustee a "lost  certificate
bond"  or a  similar  bond in such  reasonable  sum as the  Trustee  may  direct
indemnifying  the Trustee and its agent for so doing. The Trustee shall have the
power to require  from an insurer or insurers a blanket  lost  security  bond or
bonds in respect of the  replacement  of lost,  stolen,  destroyed  or mutilated
Certificates.  The  Trustee  shall pay all  premiums  and  other  funds of money
payable for such purpose out of the Trust Fund with such  contribution,  if any,
by those insured as may be determined by the Trustee in its sole discretion.  If
such  blanket lost  security  bond is required,  the Trustee may  authorize  and
direct  (upon such terms and  conditions  as the  Trustee  may from time to time
impose) any agent to whom the indemnity of such bond extends to take such action
to replace any lost, stolen,  destroyed or mutilated Certificate without further
action or approval by the Trustee.

12.10 Death of a Unitholder

      The death of a Unitholder  during the  continuance  of the Trust shall not
terminate  the Trust or any of the mutual or respective  rights and  obligations
created  by  or  arising  under  this   Declaration  of  Trust,  nor  give  such
Unitholder's  personal  representative  a right to an  accounting or to take any
action in court or otherwise against other  Unitholders,  the Trust, the Trustee
or the Trust  Fund,  but  shall  entitle  the  personal  representatives  of the
deceased Unitholder to demand and receive,  pursuant to the provisions hereof, a
new  Certificate  for  Units in place of the  Certificate  held by the

                                     - 44 -



deceased   Unitholder,   and  upon  the   acceptance   thereof   such   personal
representatives  shall  succeed to all rights of the deceased  Unitholder  under
this Declaration of Trust.

12.11 Unclaimed Interest or Distribution

      In the event that the  Trustee  shall hold any amount of interest or other
distributable  amount which is unclaimed or which cannot be paid for any reason,
the Trustee  shall be under no  obligation  to invest or reinvest the same,  but
shall  only be obliged  to hold the same in a current  interest-bearing  account
pending payment to the Person or Persons entitled thereto. The Trustee shall, as
and when required by law, and may at any time prior to such required  time,  pay
all or part of such interest or other distributable amount so held to the Public
Trustee (or other appropriate government official or agency) whose receipt shall
be a good discharge and release of the Trustee.

12.12 Exchanges of Certificates

      Certificates  representing  any number of Units may be  exchanged  without
charge  for  Certificates  representing  an  equivalent  number  of Units in the
aggregate.  Any  exchange  of  Certificates  may be made at the  offices  of the
Trustee or at the offices of any Transfer  Agent where  registers are maintained
for the  Certificates  pursuant  to the  provisions  of  this  Article  12.  Any
Certificates  tendered  for  exchange  shall be  surrendered  to the  Trustee or
appropriate Transfer Agent and shall be cancelled.

"3.8  Non-Resident Unitholders

      It is in the best interest of Unitholders that the Trust always qualify as
a "mutual fund trust" under the Income Tax Act. Accordingly,  in order to ensure
the maintenance of such status:

      (a)   The Corporation shall:

            (i)   prior  to the  completion  of any  transaction  involving  the
                  acquisition by the Trust of any Subsequent Investment;

            (ii)  prior to any  material  modification  to the Trust  Fund other
                  than as contemplated by paragraph (i);

            (iii) promptly   following  any  proposed   amendment  to  paragraph
                  132(7)(a)  of the  Income  Tax Act or the  publication  of any
                  administrative  bulletin  or other  notice  of  interpretation
                  relating to the interpretation or application of such section;
                  or

            (iv)  otherwise at any time requested by the Trustee,

            obtain an opinion of Counsel confirming whether the Trust is, at the
            date thereof and following  such  transaction or event (which in the
            case of  paragraph  (iii)  shall mean the coming  into effect of the
            amendment  or  change  of  interpretation),   entitled  to  rely  on
            paragraph  132(7)(a)  of  the  Income  Tax  Act  (or  any  successor
            provision  thereto)  for  purposes of  qualifying  as a "mutual fund
            trust" under the Income Tax Act.

      (b)   If at any time the board of directors of the Corporation determines,
            in its sole discretion, or becomes aware, pursuant to Section 3.8(a)
            or  otherwise,  that the  Trust's  ability  to  continue  to rely on
            paragraph  132(7)(a)  of  the  Income  Tax  Act  (or  any  successor
            provision  thereto)  for  purposes of  qualifying  as a "mutual fund
            trust"  thereunder  is  in  jeopardy,   then  forthwith  after  such
            determination:

            (i)   it shall  be the sole  responsibility  of the  Corporation  to
                  monitor the holdings by Non-Residents; and

            (ii)  the  Corporation  shall  take such steps as are  necessary  or
                  desirable to ensure that the Trust is not maintained



                                      - 4 -

                  primarily for the benefit of  non-residents  of Canada (within
                  the  meaning  of the  Income  Tax  Act) or that  the  Trust is
                  otherwise able to continue to qualify as a mutual fund trust.

      (c)   The Corporation  may, at any time and from time to time, in its sole
            discretion,  request that the Trustee make  reasonable  efforts,  as
            practicable  in the  circumstances,  to  obtain  declarations  as to
            beneficial  ownership under Section 8.11, perform residency searches
            of unitholder and beneficial  unitholder  mailing  address lists and
            take such other steps specified by the  Corporation,  at the cost of
            the Trust,  to determine or estimate as best  possible the residence
            of the beneficial owners of Trust Units.

      (d)   If at any time the board of  directors  of the  Corporation,  in its
            sole  discretion,  determines that it is in the best interest of the
            Trust, the Corporation,  notwithstanding the ability of the Trust to
            continue to rely on  paragraph  132(7)(a)  of the Income Tax Act for
            the purpose of  qualifying as a "mutual fund trust" under the Income
            Tax Act, may:

            (i)   require  the  Trustee to refuse to accept a  subscription  for
                  Trust  Units  from,  or issue or  register a transfer of Trust
                  Units to, a person unless the person provides a declaration to
                  the Corporation  pursuant to Section 8.11 that the Trust Units
                  to be  issued  or  transferred  to such  person  will not when
                  issued or transferred be beneficially  owned by a non-resident
                  of Canada;

            (ii)  to the extent practicable in the circumstances,  send a notice
                  to  registered  holders of Trust Units which are  beneficially
                  owned by non-residents  of Canada,  chosen in inverse order to
                  the order of acquisition or  registration  of such Trust Units
                  beneficially owned by non-residents of Canada or in such other
                  manner  as  the   Corporation   may  consider   equitable  and
                  practicable,  requiring  them to sell their  Trust Units which
                  are  beneficially  owned  by  non-residents  of  Canada  or  a
                  specified  portion  thereof  within a specified  period of not
                  less than 60 days. If the  Unitholders  receiving  such notice
                  have not sold the  specified  number  of such  Trust  Units or
                  provided the Corporation with satisfactory evidence that such



                                      - 5 -

                  Trust Units are not beneficially owned by non-residents within
                  such period, the Corporation may, on behalf of such registered
                  Unitholder, sell such Trust Units and, in the interim, suspend
                  the  voting and  distribution  rights  attached  to such Trust
                  Units and make any distribution in respect of such Trust Units
                  by  depositing  such  amount in a separate  bank  account in a
                  Canadian  chartered  bank (net of any applicable  taxes).  Any
                  sale  shall be made on any stock  exchange  on which the Trust
                  Units are then  listed  and,  upon  such  sale,  the  affected
                  holders  shall  cease to be holders of Trust Units so disposed
                  of and their  rights  shall be  limited to  receiving  the net
                  proceeds  of sale,  and any  distribution  in respect  thereof
                  deposited as aforesaid,  net of applicable  taxes and costs of
                  sale,  upon surrender of the  Certificates  representing  such
                  Trust Units;

            (iii) delist the Trust Units from any  non-Canadian  stock exchange;
                  and

            (iv)  take  such  other  actions  as the board of  directors  of the
                  Corporation   determines,   in  its   sole   discretion,   are
                  appropriate in the circumstances that will reduce or limit the
                  number of Trust  Units  held by  non-resident  Unitholders  to
                  ensure  that the  Trust is not  maintained  primarily  for the
                  benefit of non-residents of Canada.

      (e)   The Trustee shall have no liability for amounts received pursuant to
            sales of Trust Units made pursuant to Section 3.8(d)(ii).  Except as
            specifically set out herein, the Trustee shall not be bound to do or
            take any  proceeding  or action with  respect to this Section 3.8 by
            virtue of the  powers  conferred  on it under  this  Declaration  of
            Trust.  The  Trustee  shall  not be  deemed  to have  notice  of any
            violation  of this  Section  3.8  unless and until it has been given
            written  notice of such  violation and shall be required to act only
            as  required  by this  Declaration  of Trust  and upon an  indemnity
            satisfactory to the Trustee being provided by the Trust. The Trustee
            shall not be required to actively monitor the non-resident  holdings
            of the Trust. It is acknowledged that the Trustee cannot monitor the
            non-resident holders of the Trust Units given that many of the Trust
            Units  are  registered  in  the  name  of  depositories   and  other
            non-beneficial holders.



                                      - 6 -

            The  Trustee   shall  not  be  liable  for  any   violation  of  the
            non-resident  ownership  restriction  in this  Section 3.8 which may
            occur during the term of the Trust.

      (f)   Notwithstanding  any other  provision of this  Declaration of Trust,
            non-resident  Unitholders,  whether registered holders or beneficial
            holders of Trust Units,  shall not be entitled to vote in respect of
            any Special Resolutions to amend this Section 3.8."
