                         ISSUE AND SALE OF TRUST UNITS

3.1      NATURE AND RANKING OF TRUST UNITS

(a)    The beneficial  interests in the Trust shall be divided into two classes
       of Trust Units,  described and  designated  as Ordinary  Trust Units and
       Special  Trust Units,  which shall be entitled to the rights and subject
       to the limitations,  restrictions and conditions set out herein; and the
       interest  of each  Unitholder  shall  be  determined  by the  number  of
       Ordinary  Trust Units or Special  Trust Units  registered in the name of
       the Unitholder.

       one vote at any meeting of the  Unitholders  and each Special Trust Unit
       shall entitle the holder or holders thereof to  three-sixteenths  of one
       vote at any meeting of the  Unitholders.  Each Trust Unit  represents an
       equal fractional  undivided beneficial interest in any distribution from
       the Trust  (whether of net income,  net realized  capital gains or other
       amounts) and in any net assets of the Trust in the event of  termination
       or winding-up  of the Trust.  All Trust Units  outstanding  from time to
       time shall be entitled to equal shares in any distributions by the Trust
       and, in the event of termination or winding-up of the Trust,  in the net
       assets of the Trust. All Trust Units shall rank among themselves equally
       and rateably without discrimination, preference or priority.

(c)    All Trust Units of the Trust  issued and  outstanding  prior to the date
       hereof  are and shall be deemed to be  Ordinary  Trust  Units and unless
       otherwise  designated  as Special  Trust  Units,  all Trust Units issued
       after the date hereof shall be deemed to be Ordinary Trust Units.

(d)    In accordance with and at such time as Subsection  3.1(s) of the Plan of
       Arrangement is deemed to occur in accordance  with the terms of the Plan
       of  Arrangement,  the  number of  outstanding  Trust  Units held by such
       Unitholders  shall be  consolidated  such that each Unitholder will hold
       after  such  consolidation  the  same  number  of  Trust  Units  as  the
       Unitholder held before such  distribution of additional Trust Units; and
       each  certificate  representing  a number  of Trust  Units  before  such
       distribution  of additional  Trust Units is deemed to represent the same


                                      10


       number of Trust Units after such  distribution of additional Trust Units
       and  consolidation.  The Corporation  will provide written notice to the
       Trustee as soon as reasonably  practicable after such  consolidation has
       taken effect.

         Immediately  after the Closing,  the Trust will repurchase the initial
Trust  Units from the  Trustee,  and the Trustee  shall sell the initial  Trust
Units to the Trust for a purchase  price of one hundred  dollars and,  upon the
completion  of such  purchase  and  sale,  the  initial  Trust  Units  shall be
cancelled  and shall no longer be  outstanding  for any of the purposes of this
Indenture.

3.5      OFFERINGS OF TRUST UNITS AND INDEBTEDNESS

(a)    Trust Units, including rights, warrants or other securities to purchase,
       to convert into or exchange  into Trust Units,  may be created,  issued,
       sold  and  delivered   pursuant  to  Offering  Documents  on  terms  and
       conditions  and at such  time or times as the  board  of  directors  the
       Corporation may determine.

(b)    The board of directors of the Corporation may authorize the creation and
       issuance of debentures, notes and other evidences of indebtedness of the
       Trust which debentures,  notes or other evidences of indebtedness may be
       created  and issued from time to time on such terms and  conditions,  to
       such  persons  and  for  such   consideration  as  the  Corporation  may
       determine.

3.6      RANKING OF TRUST UNITS

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

3.7      TRUST UNITS FULLY PAID AND NON-ASSESSABLE

         Trust  Units shall be issued only when fully paid in money or property
or past  service,  provided  that  property  will include a promissory  note or
promise to pay given by the allottee.  The Unitholders  shall not thereafter be
required to make any  further  contribution  to the Trust with  respect to such
Trust Units.

3.8      NO CONVERSION, RETRACTION, REDEMPTION OR PRE-EMPTIVE RIGHTS

         No person shall be entitled, as a matter of right, to subscribe for or
purchase any Trust Unit.  There are no  conversion,  retraction,  redemption or
pre-emptive rights attaching to the Trust Units.

3.9      CONSOLIDATION OF TRUST UNITS

         Immediately  after any pro rata distribution of additional Trust Units
to all  Unitholders  pursuant to  Sections  5.5 or Section  5.8,  the number of
outstanding  Trust Units will be  consolidated  such that each  Unitholder will


                                      11


hold after the  consolidation  the same number of Trust Units as the Unitholder
held before the  distribution  of  additional  Trust  Units.  In such case,  if
applicable,  each Trust Unit  Certificate  representing a number of Trust Units
prior to the  distribution of additional Trust Units is deemed to represent the
same number of Trust Units after the distribution of additional Trust Units and
the consolidation.

3.10     SPECIAL VOTING RIGHTS

         In addition to Trust Units,  there may be issued  special voting units
("Special Voting Units")  entitling the holders thereof to such number of votes
at meetings of  Unitholders  as may be  prescribed by the Board of Directors of
the Corporation in the resolution  authorizing the issuance of any such Special
Voting Units. Except for the right to vote at meetings of the Unitholders,  the
Special  Voting  Units  shall not confer  upon the  holders  thereof  any other
rights;  and for greater  certainty,  the holders of Special Voting Units shall
not be entitled to any distributions of any nature whatsoever from the Trust or
have any  beneficial  interest in any assets of the trust on termination of the
Trust.

3.11     NON-RESIDENT HOLDERS

         It is in the best interest of Unitholders  that the Trust qualify as a
"unit trust" and a "mutual fund trust"  under the Tax Act.  Accordingly,  it is
intended  that the Trust  comply  with the  requirements  under the Tax Act for
"unit  trusts" and "mutual  fund  trusts" at all  relevant  times such that the
Trust  maintain the status of a unit trust and a mutual fund trust for purposes
of the Tax Act. In this regard, the Trust shall,  among other things,  take all
necessary  steps to monitor the  ownership of the Trust Units to carry out such
intentions.  If at any time the Trust, becomes aware that the beneficial owners
of 49% or more of the Trust Units then  outstanding are or may be Non-Residents
or that such a situation is imminent,  the Trust, by or through the Corporation
on the Trust's behalf,  shall take such action as may be necessary to carry out
the   intentions   evidenced   herein.   For  the  purposes  of  this  Section,
"Non-Residents"  means  non-residents  of Canada  within the meaning of the Tax
Act.

                           INVESTMENTS OF TRUST FUND

                                      12


4.2      PERMITTED INVESTMENTS

         Any funds  within the Trust Fund that are not  required to be invested
as provided in Section 4.1 shall be used by the Trust only to acquire Permitted
Investments or as permitted by Section 7.2(f) or Section 7.2(u).

4.3      OTHER INVESTMENT RESTRICTIONS

         Notwithstanding  anything  contained  in  this  Indenture,   under  no
circumstances  shall the Trustee acquire any investment  which (a) would result
in the cost amount to the Trust of all  "foreign  property"  (as defined in the
Tax Act)  which  is held by the  Trust  to  exceed  the  amount  prescribed  by
Regulation  5000(l) of the regulations to the Tax Act, (b) is a "small business
security" as that term is used in Part L1 of the Regulations to the Tax Act, or
(c) would result in the Trust not being  considered  either a "unit trust" or a

and receive  direction from the  Corporation  with respect to any investment to
ensure compliance with this provision.

                                   ARTICLE 5
                                 DISTRIBUTIONS

5.1      DETERMINATION OF NET INCOME OF THE TRUST

         In this Article 5, the "Net Income of the Trust" for the period ending
on a Distribution  Record Date shall be the amount  calculated,  for the period
commencing  immediately  following the preceding  Distribution Record Date (or,
for the first  Distribution  Record  Date,  the period  commencing  on the date
hereof) and ending on such Distribution Record Date, on the following basis:

(a)    any amounts received pursuant to the NPI and the Direct  Royalties,  any
       interest or other income from  Permitted  Investments,  ARTC received by
       the  Trust  and  other  Crown  charges  that are not  deductible  by the
       Corporation for income tax purposes and that are reimbursed by the Trust
       to the  Corporation  shall be  included in Net Income of the Trust on an
       accrual basis and shall accrue from day to day;

(b)    dividends  on the Shares or any other  dividends  on  securities  of the
       Corporation  shall be included in Net Income of the Trust when  received
       including  dividends  deemed to have  been  received  on such  Shares or
       securities pursuant to the Tax Act; and

(c)    all  expenses  and  liabilities  of the Trust,  including  Debt  Service
       Charges,  which are due or accrued  and which are  chargeable  to income
       shall be deducted in computing Net Income of the Trust.

Items of income or expense  not  provided  for above or in Section 5.3 shall be
included in such calculation on such basis as may be considered  appropriate by
the Trustee upon the recommendation of the Corporation.

5.2      NET INCOME OF THE TRUST TO BECOME PAYABLE

         The Trustee may, upon the  recommendation  of the  Corporation,  on or
before any Distribution Record Date, declare payable to the Unitholders on that
Distribution Record Date all or any part of the Net Income of the Trust for the
period ending on that  Distribution  Record Date  determined in accordance with
Section 5.1. The share of each Unitholder in the amount so payable shall be the
Pro Rata Share of such  Unitholder  determined as at that  Distribution  Record
Date;  and  subject  to  Section  5.7,  such  amount  shall be  payable on that
Distribution Record Date.  Notwithstanding the foregoing, the amount of any Net
Income of the Trust 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 shall not
be payable by the Trust to Unitholders.  Notwithstanding the foregoing, holders
of Special  Trust  Units on any  particular  Distribution  Record Date shall be
entitled to a preferential  distribution  equal to $0.02 for each Special Trust
Unit, or such lesser amount where the Net Income  declared to be payable by the
Trustee  would not be  sufficient  to pay such  amount,  and the Pro Rata Share
payable  to   Unitholders   shall  be   determined   after  such   preferential
distribution.


                                      13


5.3      NET REALIZED CAPITAL GAINS TO BECOME PAYABLE

         The Trustee may, on or before any  Distribution  Record Date,  declare
payable to the Unitholders on that Distribution  Record Date all or part of the
net realized  capital gains of the Trust to the extent not previously  declared
payable. The share of each Unitholder in the amount so payable shall be the Pro
Rata Share of such Unitholder  determined as at that Distribution  Record Date;
and subject to Section 5.7,  such amount shall be payable on that  Distribution
Record Date.  For the purposes of this Article 5, "net realized  capital gains"
of the Trust  means the total of all capital  gains  realized by the Trust less
the total of all capital losses realized by the Trust.

5.4      NET INCOME AND NET REALIZED CAPITAL GAINS FOR INCOME TAX PURPOSES TO
         BECOME PAYABLE

         On December 31 of each year,  an amount equal to the Net Income of the
Trust for such year  (excluding  net  realized  capital  gains)  determined  in
accordance  with the Tax Act, other than  paragraph  82(1)(b)  thereof,  to the
extent not  previously  payable  pursuant  to Section  5.2 on any  Distribution
Record Date in the year  (including  December  31 of that  fiscal  year) to any
Unitholder,  shall be  declared  payable to  Unitholders  as at the end of that
year.  The share of each  Unitholder  in the amount so payable shall be the Pro
Rata Share of such Unitholder determined as at the end of such year.

         On  December  31 of each  fiscal  year,  an  amount  equal  to the net
realized  capital  gains of the Trust,  to the extent  not  previously  payable
pursuant  to Section  5.3 on any  Distribution  Record Date or pursuant to this
paragraph on any prior December 31, shall be declared payable to Unitholders as
at the end of that fiscal year.  The share of each  Unitholder in the amount so
payable shall be the Pro Rata Share of such Unitholder determined as at the end
of such year.

         Any amounts payable pursuant to this Section 5.4 may, at the option of
the Trustee,  be paid through a distribution of additional Trust Units having a
value equal to the amount  payable.  For the  purposes of this Section 5.8, the
value of the  additional  Trust  Units  issued  shall be  determined  using the
closing  trading price (or, if there was no trade,  the average of the last bid
and the last ask  prices) of the Trust Units on December 31 (or, if December 31
is not a Business  Day, on the last  preceding  Business  Day) on the principal
stock exchange where the Trust Units are listed or, if no so listed, such other
value as the Trustee shall determine.

5.5      OTHER AMOUNTS

         Any amounts not otherwise payable to Unitholders prior to the end of a
particular fiscal year of the Trust pursuant to the provisions of Article 5 may
be declared by the Trustee,  upon the recommendation of the Corporation,  to be
payable to Unitholders in the same manner as provided for in Section 5.2.

5.6      ENFORCEMENT

         Each Unitholder  shall have the right to enforce payment of any amount
payable to the Unitholder under this Article 5 (or a distribution of additional
Trust Units under  Section 5.8, if  applicable)  at the time the amount  became
payable unless a Payment Date is specified under Section 5.7 in respect of such
amount  payable,  in which case the right to enforce payment shall arise at the
later of the time the amount  became  payable and the  applicable  Payment Date
specified under Section 5.7.

5.7      PAYMENT OF AMOUNTS PAYABLE

         Amounts payable to Unitholders pursuant to Sections 5.2 and 5.3 may be
paid by the Trust on any date (the "Payment Date")  specified by the Trustee as
the  applicable  Distribution  Record  Date,  or a day within 30 days after the
applicable Distribution Record Date and in the same calendar year.

5.8      DISTRIBUTION OF ADDITIONAL TRUST UNITS

         Where  after the last  Distribution  Record  Date and on or before the
next Distribution  Record Date an amount or amounts of cash has or have been or
is or are being paid under Section 18.3 in respect of Trust Units  tendered for


                                      14


redemption,  the distribution  payable to Unitholders on such next Distribution
Record Date shall include a  distribution  of  additional  Trust Units having a
value equal to the aggregate of such amounts,  in which case the amount of cash
to be distributed on the distribution shall be reduced by the aggregate of such
amounts.  In addition,  if on any  Distribution  Record Date the Trust does not
have cash in an amount  sufficient to pay the full  distribution  to be made on
such Distribution Record Date in cash, the distribution  payable to Unitholders
on such Distribution  Record Date may, at the option of the Trustee,  include a
distribution  of  additional  Trust  Units  having  a value  equal  to the cash
shortfall,  in  which  case  the  amount  of  cash  to be  distributed  on  the
distribution  shall be reduced by the  amount of such cash  shortfall.  For the
purposes of this  Section 5.8,  the value of the  additional  Trust Units to be
issued shall be determined  using the closing trading price (or if there was no
trade,  the average of the last bid and the last ask prices) of the Trust Units
on the Distribution  Record Date (or, if the Distribution  Record Date is not a
Business Day, on the last Business Day preceding the Distribution  Record Date)
on the principal  stock exchange where the Trust Units are listed or, if not so
listed, such other value as the Trustee shall determine.

5.9      WITHHOLDING TAXES

         For  greater  certainty,  in the  event  that  withholding  taxes  are
exigible on any  distributions  or redemption  amounts  distributed  under this
Indenture,  the Trustee shall withhold the withholding taxes required and shall
promptly remit such taxes to the  appropriate  taxing  authority.  In the event
that withholding taxes are exigible on any distributions or redemption  amounts
distributed under this Indenture and the Trustee is, or was, unable to withhold
taxes from a  particular  distribution  to a  Unitholder  or has not  otherwise
withheld taxes on past  distributions  to the Unitholder,  the Trustee shall be
permitted to withhold amounts from other distributions to satisfy the Trustee's
withholding tax obligations.

                APPOINTMENT, RESIGNATION AND REMOVAL OF TRUSTEE

6.1      TRUSTEE'S TERM OF OFFICE

         Subject  to  Sections  6.2 and 6.3,  Valiant  Trust  Company is hereby
appointed as Trustee hereunder for an initial term of office which shall expire
upon the conclusion of the first annual meeting of Unitholders. The Unitholders
shall, at the first annual meeting of the Unitholders, re-appoint, or appoint a
successor to the Trustee,  and thereafter,  the Unitholders  shall reappoint or
appoint a  successor  to the  Trustee  on each  successive  annual  meeting  of
Unitholders  following the reappointment or appointment of the successor to the
Trustee.  Any such  reappointment  or  appointment  shall be made  either by an
Ordinary  Resolution  at such  meeting of  Unitholders  or shall be made in the
manner set out in Section 6.4.  Notwithstanding the foregoing,  if a Trustee is
not reappointed at the meeting of Unitholders held immediately  before the term
of office of such  Trustee  expires  and if no  successor  to such  Trustee  is
appointed at that meeting,  such Trustee  shall  continue to hold the office of
Trustee under this Indenture until a successor has been appointed under Section
6.4.

6.2      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;  provided that no
such  resignation  shall  be  effective  until  (i)  the  appointment  of,  and
acceptance of such  appointment by, a new Trustee in the place of the resigning
Trustee has been made in the manner set out in Section  6.4, and (ii) the legal
and valid  assumption  by the new  Trustee of all  obligations  of the  Trustee
related hereto in the same capacities as the resigning Trustee.

6.3      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  in Section  6.6, 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 Indenture or as a result of a material increase in


                                      15


the fees  charged by the  Trustee.  No decision to remove a Trustee  under this
Section 6.3 shall become  effective until (i) approved by a Special  Resolution
at a meeting of Unitholders  duly called for that purpose (ii) the  appointment
of, and acceptance of such  appointment  by, a new Trustee under Section 6.4 in
the  place of the  Trustee  to be  removed,  and  (iii)  the  legal  and  valid
assumption by the new Trustee of all  obligations of the Trustee related hereto
in the same capacities as the resigning Trustee.

6.4      APPOINTMENT OF SUCCESSOR TO TRUSTEE

(a)    A  successor  Trustee to a Trustee  which has been  removed by a Special
       Resolution of  Unitholders  under Section 6.3,  shall be appointed by an
       Ordinary  Resolution  at a meeting of  Unitholders  duly called for that
       purpose, provided the successor meets the requirements of Section 6.6.

(b)    Subject to Section 6.6, the  Corporation  may appoint a successor to any
       Trustee  which  has  been  removed  by  a  Special   Resolution  of  the
       Unitholders  under Section 6.3, or which has not been reappointed  under
       Section 6.1, if the Unitholders fail to do so at such meeting.

(c)    Subject to Section 6.6, the  Corporation  may appoint a successor to any
       trustee which has given a notice of resignation under Section 6.2.

No appointment of any successor Trustee shall be effective until such successor
Trustee shall have complied with the provisions of Section 6.2(ii).

6.5      FAILURE TO APPOINT SUCCESSOR

         In the event that no successor  Trustee to a Trustee who has delivered
a notice of  resignation  in  accordance  with Section 6.2, or who has received
notice of removal in accordance  with Section 6.3, has accepted an  appointment
within  120  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.

6.6      QUALIFICATIONS OF TRUSTEE

         The Trustee and any successor to the Trustee or new Trustee  appointed
under  this  Article 6 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 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  company and must have  undertaken  in writing to discharge
all  of  the  obligations  and  responsibilities  of  the  Trustee  under  this
Indenture.

                                   ARTICLE 7

       owner thereof except as specifically designated in Subsection (b) below.
       The  responsibilities  of the Trustee  hereunder are however  limited to
       those  specific  powers  granted to it  (subject to  delegations  to the

       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.

       Trustee  shall,  execute  any  agreements  on behalf of the Trust as the
       Corporation  shall have  authorized  within the scope of the exercise of
       any such rights, powers or privileges.

7.2      SPECIFIC POWERS AND AUTHORITIES

         Subject only to the express  limitations  contained in this  Indenture
and in  addition  to any powers and  authorities  conferred  by this  Indenture
(including,  without  limitation,  Section 7.1 hereof) or which the Trustee may

shareholders,  or agents. If the Trustee has retained an appropriate  expert or
adviser or Counsel with respect to any matter  connected  with its duties under

         The  Corporation  hereby  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,  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.

       Trust Units and the maintenance of registers of Unitholders;

(b)    terminating this Indenture in accordance with the provisions hereof;

fact,  to sign on behalf of the Trust all rights  plans,  prospectuses,  annual
information forms, management proxy circulars, other Offering Documents and any
other documents ancillary or similar thereto required to be signed by the Trust
from  time to time,  including  any  Agency  Agreements,  indemnity  agreements

documents ancillary or similar thereto.

8.5      LIABILITY OF TRUSTEE

       Royalties  Sale  Agreement  and any other  agreement of the Trust or 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
       prejudiced thereby;

(e)    providing for the  electronic  delivery by the Trust to  Unitholders  of
       documents relating to the Trust (including annual and quarterly reports,
       including  financial  statements,  notices of  Unitholder  meetings  and
       information  circulars  and proxy  related  materials)  once  applicable
       securities laws have been amended to permit such electronic  delivery in
       place of normal  delivery  procedures,  provided that such amendments to
       the Trust  Indenture  are not contrary to or do not  conflict  with such
       laws;

(f)    making  such other  amendments  which in the  opinion of the Trustee are
       necessary  or  desirable  as a result of changes or proposed  changes in
       taxation laws or the administration or enforcement thereof;

(g)    changing the situs of, or the laws  governing  the Trust  which,  in the

(h)    curing,   correcting  or  rectifying  any   ambiguities,   defective  or

votes  required to be cast at a meeting of the  Unitholders  for the purpose of
amending  this  Section  9.1  without  the consent of the holders of all of the
Trust Units then outstanding.

                                  ARTICLE 10
                            MEETINGS OF UNITHOLDERS

10.1     ANNUAL AND SPECIAL MEETINGS OF UNITHOLDERS

         Annual  meetings of the  Unitholders  shall be called by the  Trustee,
commencing  in  2003,  on a day,  at a time  and  at a  place  to be set by the
Corporation.  The  business  transacted  at such  meetings  shall  include  the
transaction  of such  business as  Unitholders  may be entitled to vote upon as
hereinafter  provided in this Article 10, or as the  Corporation may determine.
Special  meetings  of  the  Unitholders  may  be  called  at  any  time  by the
Corporation  and shall be called by the  Corporation  upon a written request of
Unitholders  holding in the aggregate not less than 20% of the Trust 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 the  Corporation  shall  designate.  The
Chairman of any annual or special  meeting shall be a person  designated by the
Corporation  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 Corporation.

10.2     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 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.

10.3     QUORUM

         At any meeting of the Unitholders,  subject as hereinafter provided, a
quorum  shall  consist  of two or more  persons  either  present  in  person or
represented by proxy and  representing in the aggregate not less than 5% of the
outstanding  Trust 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 fourteen (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 form 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.

10.4     VOTING RIGHTS OF UNITHOLDERS

         Only  Unitholders  of record  shall be entitled to vote and each Trust
Unit shall  entitle  the holder or holders of that Trust Unit to that number of
votes at any  meeting  of the  Unitholders  set  forth in  Section  3.1.  Every
question submitted to a meeting, other than a Special Resolution, shall, unless
a poll vote is  demanded,  be decided by a show of hands  vote,  on which every
person  present and  entitled  to vote shall be  entitled  to one vote.  At any
meeting of Unitholders,  any holder of Trust 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  prior to the  commencement of such meeting no later than the time
for which  proxies are to have been received as set forth in the notice of such
meeting.  If approved by the  Trustee,  proxies may be solicited in the name of
the Trustee. When any Trust Unit is held jointly by several persons, any one of
them may vote at any  meeting  in person or by proxy in  respect  of such Trust
Unit,  but if more than one of them shall be present at such  meeting in person
or by proxy,  and such joint owners of 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 11.3 shall be entitled to
cast such vote.


                                      27


10.5     RESOLUTIONS

(a)    The Trustee shall in accordance  with an Ordinary  Resolution  passed by
       the  Unitholders:  (i) change the Auditors as provided in Section  15.3;
       and (ii) elect the directors of the Corporation.

(b)    The Trustee shall in accordance with a Special  Resolution passed by the
       Unitholders:

       (i)   subject to Section 9.1, amend this Indenture;

       (ii)  subdivide or consolidate Trust Units;

       (iii) sell or  agree  to  sell  the  property  of the  Trust  Fund as an
             entirety or substantially as an entirety;

       (v)   commence  to  wind-up  and  wind-up  the  affairs  of the Trust if

Except with  respect to the above  matters set out in this Section 10.5 and the
matters set forth in Sections 6.3, 6.4 and 12.2 hereof,  no action taken by the
Unitholders  or resolution of the  Unitholders  at any meeting shall in any way
bind the Trustee.  Notwithstanding the foregoing,  the Trust, without the prior
approval of the Unitholders  whether by Special Resolution or otherwise,  shall
be permitted to sell, assign or otherwise transfer any property of the Trust in
circumstances  where any such sale,  assignment or transfer is effected between
or among the Trust and any one or more of:

             (A)    any  direct  or  indirect  wholly-owned  subsidiary  of the
                    Trust;

             (B)    any trust, the only beneficiaries of which are the Trust or
                    any  direct  or  indirect  wholly-owned  subsidiary  of the
                    Trust;

             (C)    any  partnership,  the only partners of which are the Trust
                    and/or any of the  persons  referred to in (A) or (B) above
                    and/or

             (D)    the Corporation,

provided  that in opinion of the board of  directors of the  Corporation,  such
sale, assignment or transfer of property is in the best interests of the Trust.

10.6     MEANING OF "SPECIAL RESOLUTION"

         The expression "Special Resolution" when used in this Indenture means,
subject as hereinafter in this Article  provided,  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 Article at which two or more holders of at least 10% of
the aggregate  number of Trust Units then  outstanding are present in person or
by proxy and passed by the affirmative votes of the holders of not less than 66
2/3% of the Trust  Units  represented  at the  meeting and voted on a poll upon
such resolution.

         If, at any such meeting, the holders of 10% of the aggregate number of
Trust  Units  outstanding  are not  present in person or  represented  by proxy
within 30 minutes 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  10.2.
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  form a quorum  and may  transact  the


                                      28


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 10.6 shall be a Special  Resolution  within the meaning of this
Indenture,  notwithstanding  that the holders of less than 10% of the aggregate
number of Units then  outstanding  are present or  represented by proxy at such
adjourned meeting.

         Votes on a Special  Resolution  shall always be given on a poll and no
demand  for a poll on a  Special  Resolution  shall be  necessary.  No  Special
Resolution  changing or amending any provision hereof relating to or affecting:
(i) the Trustee, including the qualification, powers, authorities, appointment,
removal or resignation  thereof; or (ii) the provisions of Articles 9, 10 or 12
shall be  effective  prior to 60 days from the adoption  thereof in  accordance
with the  provisions  hereof  or such  shorter  period  as may be  approved  by
Unitholders.

10.7     RECORD DATE FOR VOTING

         For the purpose of  determining  the  Unitholders  who are entitled to
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 vote at such meeting or any adjournment thereof, and any Unitholder
who was a  Unitholder  at the time so fixed  shall be  entitled to vote at such
meeting or any adjournment  thereof even though he has since that time disposed
of his Trust Units, and no Unitholder becoming such after that time shall be so
entitled to 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
10.2.

10.8     BINDING EFFECT OF RESOLUTIONS

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

10.9     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,  as near as may be possible,
with  all  provisions  of the  BUSINESS  CORPORATIONS  ACT  (Alberta)  and  the
requirements of Canadian securities  legislation applicable to the solicitation
of proxies.

10.10    NO BREACH

         Notwithstanding  any provisions of this Indenture,  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.

                                   ARTICLE 11
             CERTIFICATES, REGISTRATION AND TRANSFER OF TRUST UNITS

11.1     NATURE OF TRUST UNITS

         The nature of a Trust Unit and the relationship of a Unitholder to the
Trustee and the  relationship  of one  Unitholder to another is as described in
Sections 2.4 and Subsection  2.5(c) and the provisions of this Article 11 shall
not in any way alter the nature of Trust Units or the said  relationships  of a
Unitholder to the Trustee and of one  Unitholder  to another,  but are intended
only to facilitate, as applicable, the issuance of certificates or entry on the


                                      29


register of Unitholders  evidencing the beneficial ownership of Trust Units and
the  recording  of all  such  transactions  whether  by the  Trust,  securities
dealers, stock exchanges, transfer agents, registrars or other persons.

11.2     CERTIFICATES

(a)    Trust Units shall be:

       (i)   represented by certificates; or

       (ii)  uncertificated  Trust  Units  evidenced  by  a  book-entry  system
             maintained by the Trustee or by a Transfer Agent designated to act
             on behalf and under the direction of the Trustee; or

       (iii) a combination of (i) and (ii) above.

(b)    If Trust Units are represented by certificates,  the form of certificate
       representing  Trust  Units  shall  be  substantially  as set  out in the
       Schedule hereto or such other form as is authorized from time to time by
       the Trustee.  Each such  certificate  shall bear an  identifying  serial
       number and shall be  certified  manually on behalf of the  Trustee.  Any
       additional   signature  required  by  the  Trustee  to  appear  on  such
       certificate  may be  printed,  lithographed  or  otherwise  mechanically
       reproduced  thereon  and, in such event,  certificates  so signed are as
       valid as if it had been signed manually.  Any certificate  which has one
       manual signature as hereinbefore provided 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.  The Trust  Certificates may be engraved,
       printed or lithographed, or partly in one form and partly in another, as
       the Trustee may determine.

(c)    Any Trust Unit  Certificate  validly  issued prior to the date hereof in
       accordance with the terms of this Indenture in effect at such time shall
       validly  represent issued and outstanding  Trust Units,  notwithstanding
       that  the form of such  Trust  Unit  Certificate  may not be in the form
       currently required by this Indenture.

11.3     REGISTER OF UNITHOLDERS

         A register shall be maintained at the principal corporate trust office
of the  Trustee in the City of Calgary  by the  Trustee or by a Transfer  Agent
designated  to act on behalf  and under the  direction  of the  Trustee,  which
register  shall  contain  the  names  and  addresses  of the  Unitholders,  the
respective numbers of Trust Units held by them, if applicable,  the certificate
numbers of the certificates  representing  such Trust Units and a record of all
transfers thereof.  Branch transfer registers shall be maintained at such other
offices of the Trustee or  Transfer  Agent as the Trustee may from time to time
designate.  The  Trustee  shall  designate  an office in the City of Toronto at
which  a  branch  register  shall  be  maintained.  Except  in the  case of the
registers  required to be maintained at the Cities of Calgary and Toronto,  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 Trust Units are so recorded 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 person registered as a
Unitholder  on the  register  of the Trust as the owner of such Trust 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 Trust  Unit or any  attempt  to
transfer,  pledge or dispose of a Trust  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 Trust Unit shall
have been transferred on the register of the Trust as herein provided.

         The  register  and the branch  transfer  register  referred to in this
Section  11.3  shall at all  reasonable  times be open  for  inspection  by the
Unitholders, the Corporation and the Trustee.


                                      30


11.4     TRANSFER OF TRUST UNITS

(a)    Subject to the  provisions  of this Article 11, the Trust Units shall be
       fully transferable without charge as between persons, but no transfer of
       Trust 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
       Trustee  or  Transfer  Agent.  No  transfer  of a Trust  Unit  shall  be
       recognized unless such transfer is of a whole Trust Unit.

(b)    Subject to the  provisions  of this  Article  11,  Trust  Units shall be
       transferable on the register or one of the branch transfer  registers of
       Unitholders  of the Trust only by the  Unitholders  of record thereof or
       their executors,  administrators  or other legal  representatives  or by
       their agents hereunto duly authorized in writing, and only upon delivery
       to the Trustee or to the Transfer  Agent of the Trust if  appointed,  of
       the certificate  therefor if a certificate  representing the Trust Units
       has been issued,  properly  endorsed or  accompanied  by a duly executed
       instrument  of transfer or a duly  executed  instrument of transfer if a
       certificate  representing the Trust Units has not been issued, in either
       case  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 that may  reasonably be
       required  by the  Trustee.  Upon such  delivery  the  transfer  shall be
       recorded on the register of  Unitholders  and, if applicable a new Trust
       Certificate  for the  residue  thereof  (if any)  shall be issued to the
       transferor.  Unless the Corporation  agrees to assume  liability for the
       transfer and exchange fees the Unitholder  shall be responsible for such
       fees and expenses.

(c)    Any person becoming  entitled to any Trust 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 Trust Units
       and, if applicable,  shall receive a new Trust Certificate therefor only
       upon production of evidence  satisfactory to the Trustee thereof and, if
       applicable,  delivery of the existing Trust  Certificate to the Trustee,
       but until such record is made the Unitholder of record shall continue to
       be and be deemed to be the holder of such Trust  Units for all  purposes
       whether or not the  Trustee  shall have  actual or other  notice of such
       death or other event.

11.5     TRUST UNITS HELD JOINTLY OR IN A FIDUCIARY CAPACITY

         The Trustee may treat two or more  persons  holding any Trust 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 Trust Certificate that any person is in any other manner
entitled  to any future,  limited or  contingent  interest in any Trust  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 Trust
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.  Where any Trust Unit is  registered  in more than one name,  the
distributions  (if any) in respect thereof may be paid to the order of all such
holders failing written instructions 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 or more  joint  holders,  the  distributions  (if any) in
respect of any Trust  Units 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.

11.6     PERFORMANCE OF TRUST

         The Trustee,  the  Unitholders and any officer 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  Trust  Units or any  interest
therein are or may be subject,  or to ascertain or enquire whether any transfer
of any such Trust 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 Unitholder.


                                      31


11.7     LOST CERTIFICATES

         In the event that any Trust Certificate is lost, stolen,  destroyed or
mutilated,  the Trustee may authorize  the issuance of a new Trust  Certificate
for the same  number of Trust  Units in lieu  thereof.  The  Trustee may in its
discretion,  before the  issuance  of such new Trust  Certificate,  require the
owner of the lost,  stolen,  destroyed or mutilated Trust  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  Trust  Certificate
and may require the applicant to supply to the Trust 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  Trust
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 Trust  Certificate
without further action or approval by the Trustee.

11.8     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  Indenture  nor  give  such
Unitholder's  personal  representative  a right  to an  accounting  or take any
action in court or otherwise  against other  Unitholders  or 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
Trust  Certificate for Trust Units in place of the Trust  Certificate,  if any,
held by the deceased Unitholder,  and upon the acceptance thereof such personal
representatives  shall succeed to all rights of the deceased  Unitholder  under
this Indenture.

11.9     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  non-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.

11.10    EXCHANGES OF TRUST CERTIFICATES

         Trust  Certificates  representing  any  number  of Trust  Units may be
exchanged  without  charge for Trust  Certificates  representing  an equivalent
number of Trust Units in the aggregate.  Any exchange of Trust Certificates may
be made at the offices of the Trustee or at the offices of any  Transfer  Agent
where  registers  are  maintained  for the Trust  Certificates  pursuant to the
provisions  of this  Article 11. Any Trust  Certificates  tendered for exchange
shall be surrendered to the Trustee or appropriate  Transfer Agent and shall be
cancelled.  The  Corporation  shall reimburse the Trustee for all exchange fees
associated with any such exchange.

ARTICLE 18
                            REDEMPTION OF TRUST UNITS

18.1     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 Trust  Units  registered  in the name of the  Unitholder  at the  prices
determined and payable in accordance with the conditions hereinafter provided.

18.2     EXERCISE OF REDEMPTION RIGHT

         To  exercise a  Unitholder's  right to require  redemption  under this
Article 18, a duly completed and properly  executed notice  requiring the Trust
to redeem Trust Units, in a form approved by the Trustee,  shall be sent to the
Trust at the head office of the Trust, together with, if applicable,  the Trust
Unit Certificate or Trust Unit Certificates  representing the Trust 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  Corporation  and is
accompanied by any further evidence that the Corporation 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  Trust  Units,  the
Unitholder  shall thereafter cease to have any rights with respect to the Trust
Units  tendered for redemption  (other than to receive the  redemption  payment
therefor) including the right to receive any distributions thereon. Trust Units
shall be  considered  to be tendered for  redemption on the date that the Trust
has, to the  satisfaction of the Corporation,  received the notice,  Trust Unit
Certificates,  if  applicable,  and other  required  documents  or  evidence as
aforesaid.

18.3     CALCULATION OF REDEMPTION PRICE BASED ON MARKET PRICE

         Subject to Section  18.6,  upon  receipt by the Trust of the notice to
redeem Trust Units in  accordance  with Section  18.2,  the holder of the Trust
Units  tendered for  redemption  shall be entitled to receive a price per Trust
Unit (hereinafter called the "Market Redemption Price") equal to the lesser of:

(a)      90% of the market price of the Trust Units on the principal market on
         which the Trust Units are quoted for trading during the 10 day trading
         period commencing immediately after the date on which the Trust Units
         were tendered to the Trust for redemption; and

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

         For the purposes of Subsection  18.3(a),  the market price shall be an
amount equal to the simple  average of the closing price of the Trust 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  Trust  Units  traded  on a
particular day, the market price shall be an amount equal to the simple average
of the average of the highest and lowest prices for each of the trading days on
which there was a trade;  and provided further that if there was trading on the
applicable  exchange  or market for fewer than 5 of the 10  trading  days,  the
market price shall be the simple  average of the following  prices  established
for  each of the 10  trading  days;  the  average  of the last bid and last ask
prices for each day on which  there was no trading;  the  closing  price of the
Trust  Units for each day that  there was  trading  if the  exchange  or market
provides a closing  price;  and the average of the highest and lowest prices of
the Trust  Units for each day that there was  trading,  if the market  provides
only the highest and lowest prices of Trust Units traded on a particular day.

         For the purposes of subsection 18.3(b), the closing market price shall
be:  an amount  equal to the  closing  price of the Trust  Units if there was a
trade on the date;  an amount  equal to the  average of the  highest and lowest
prices of Trust  Units if there was trading  and the  exchange or other  market
provides  only the  highest  and  lowest  prices  of Trust  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.

18.4     CASH PAYMENT OF MARKET REDEMPTION PRICE

         Subject  to Section  18.5,  the Market  Redemption  Price,  payable in
respect of the Trust Units  tendered for  redemption  during any calendar 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 Trust  Units were  tendered  for  redemption.
Payments  made by the Trust of the  Market  Redemption  Price are  conclusively
deemed to have been made  upon the  mailing  of a cheque in a postage  pre-paid
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 Trust Units so redeemed.

18.5     LIMITATION REGARDING CASH PAYMENT OF MARKET REDEMPTION PRICE

         Section  18.4 shall not be  applicable  to Trust  Units  tendered  for
redemption by a Unitholder if the total amount payable by the Trust pursuant to
Section 18.4 in respect of such Trust Units and all other Trust Units  tendered
for redemption in the same calendar month exceeds  $100,000;  provided that the
Corporation  may, in its sole  discretion,  waive such limitation in respect of
any  calendar  month.  If this  limitation  is not so waived for such  calendar
month,  the Market  Redemption  Price  payable  in  respect of the Trust  Units
tendered for redemption in such calendar month shall be paid on the last day of
the calendar month following such month as follows:

(a)      firstly, by the Trust distributing Notes having an aggregate principal
         amount equal to the aggregate Market Redemption Price of the Trust
         Units tendered for redemption, and,

(b)      secondly, to the extent that the Trust does not hold Notes having a
         sufficient principal amount outstanding to effect such payment, by the
         Trust issuing its own promissory notes to the Unitholders who exercise
         the right of redemption having an aggregate principal amount equal to
         any such shortfall, which promissory notes, (herein referred to as
         "Redemption Notes") shall have terms and conditions substantially
         identical to those of the Notes.

         Upon such  distribution of Notes or issuance of Redemption  Notes, the
Trust  shall be  discharged  from all  liability  to the former  Unitholder  in
respect of the Trust Units so redeemed. For greater certainty,  the Trust shall
be entitled to all interest  accrued and unpaid on the Notes so  distributed to
and including the date upon which such Notes are required to be distributed.

18.6     CALCULATION OF REDEMPTION PRICE IN CERTAIN OTHER CIRCUMSTANCES

         Section  18.3 shall not be  applicable  to Trust  Units  tendered  for
redemption by a Unitholder, if:

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

(b)      the normal trading of the outstanding Trust Units of the Trust is
         suspended or halted on any stock exchange on which the Trust Units are
         listed for trading or, if not so listed, on any market on which the
         Trust Units are quoted for trading, on the date that such Trust Units
         tendered for redemption were tendered to the Trust for redemption or
         for more than five trading days during the 10 day trading period
         commencing immediately after the date on which such Trust Units
         tendered for redemption were tendered to the Trust for redemption,

and in either such case, such Unitholder shall, instead of the Market Redemption
Price, be entitled to receive a price per Trust Unit (herein referred to as the
"Appraised Redemption Price") equal to 90% of the fair market value thereof as
determined by the Corporation as at the date upon such Trust Units were tendered
for redemption. The Appraised Redemption Price payable in respect of Trust Units
tendered for redemption in any calendar month shall be paid on the last day of
the third calendar month following the month in which such Trust Units were
tendered for redemption, by at the option of the Trust:

         (i)   cash payment, in which case the provisions of Section 18.4 shall
               apply MUTATIS MUTANDIS; or

         (ii)  in the manner  provided for in Section  18.5,  in which case the
               provisions of Section 18.5 shall apply MUTATIS MUTANDIS.

18.7     CANCELLATION OF REDEEMED TRUST UNITS

         All Trust  Units  which are  redeemed  under this  Article 18 shall be
cancelled (as shall all  certificates,  if any,  representing  such Trust Units
which are  redeemed)  and such Trust Units shall no longer be  outstanding  and
shall not be reissued.





         IN WITNESS WHEREOF each of the parties has caused these presents to be
executed by its proper officers duly authorized in its behalf as of the 1st day
of January, 2008.

TRUST  (the  "Trust")  transferable  only  on the  books  of the  Trust  by the
registered  holder  hereof  in  person  or by  attorney  duly  authorized  upon
surrender of this certificate properly endorsed.

         The Ordinary Trust Units  represented by this  certificate  are issued
upon the terms and subject to the  conditions of a fourth  amended and restated
indenture (which indenture together with all other instruments  supplemental or
ancillary thereto is herein referred to as the "Trust Indenture") dated January
1, 2008,  as amended  and/or  amended and  restated  and made  between  Harvest
Operations Corp. (the  "Corporation") and Valiant Trust Company (the "Trustee")
which  Trust  Indenture  is binding  upon all  holders of Trust  Units and,  by
acceptance of this certificate,  the holder assents to the terms and conditions
of the Trust  Indenture.  Terms  defined in the Trust  Indenture  have the same
meaning when used herein.

         A copy of the Trust Indenture  pursuant to which this  certificate and
the Ordinary Trust Units  represented  hereby are issued may be obtained by any
Unitholder on demand and on payment of reasonable  reproduction  costs from the
head office of the Trust.

         This  certificate  may only be  transferred,  upon compliance with the
conditions prescribed in the Trust Indenture, on the register to be kept at the
office of the transfer agent in the City of Calgary and the City of Toronto, as
applicable  and at such  other  place or places,  if any,  as the  Trustee  may
designate,  by the registered holder thereof or his executors or administrators
or other legal  representatives  or his or their  attorney duly appointed by an
instrument in writing in form and execution  satisfactory  to the Trustee,  and

         The Trust Indenture contains provisions for the holding of meetings of
Unitholders and rendering  resolutions passed at such meetings binding upon all
Unitholders.

of Ordinary Trust Units to carry out such intentions. If at any time the Trust,
becomes aware that the  beneficial  owners of 49% or more of the Ordinary Trust
Units then  outstanding are or may be non-residents or that such a situation is
imminent, the Trust, by or through the Corporation on the Trust's behalf, shall
take such action as may be necessary to carry out the  intentions  evidenced in
the Indenture.

         The Trust  Indenture  provides  that no  Unitholder  shall incur or be
subject to any liability in connection  with the Trust Fund or the  obligations
or the affairs of the Trust or with respect to any act performed by the Trustee
or by any other person pursuant to the Trust Indenture.

         The Trust Indenture provides that Ordinary Trust Units shall be issued

make any further  contribution to the Trust with respect to such Ordinary Trust
Units.

surrender of this certificate properly endorsed.

         The Special Trust Units  represented  by this  certificate  are issued
upon the terms and subject to the  conditions of a fourth  amended and restated
indenture (which indenture together with all other instruments  supplemental or
ancillary thereto is herein referred to as the "Trust Indenture") dated January
1, 2008,  as amended  and/or  amended and  restated  and made  between  Harvest
Operations Corp. (the  "Corporation") and Valiant Trust Company (the "Trustee")
which  Trust  Indenture  is binding  upon all  holders of Trust  Units and,  by
acceptance of this certificate,  the holder assents to the terms and conditions
of the Trust  Indenture.  Terms  defined in the Trust  Indenture  have the same
meaning when used herein.

         A copy of the Trust Indenture  pursuant to which this  certificate and
the Special  Trust Units  represented  hereby are issued may be obtained by any
Unitholder on demand and on payment of reasonable  reproduction  costs from the
head office of the Trust.

         This  certificate  may only be  transferred,  upon compliance with the
conditions prescribed in the Trust Indenture, on the register to be kept at the
office of the transfer agent in the City of Calgary and the City of Toronto, as
applicable  and at such  other  place or places,  if any,  as the  Trustee  may

take such action as may be necessary to carry out the  intentions  evidenced in
the Indenture.

         The Trust  Indenture  provides  that no  Unitholder  shall incur or be
subject to any liability in connection  with the Trust Fund or the  obligations
or the affairs of the Trust or with respect to any act performed by the Trustee
or by any other person pursuant to the Trust Indenture.

         The Trust Indenture  provides that Special Trust 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 Special Trust
Units.

         This  certificate  shall not be valid for any  purpose  until it shall
have been countersigned and registered by the transfer agent of the Trust.

         IN WITNESS WHEREOF the  Corporation has caused this  certificate to be
