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

ARTICLE III
ISSUE OF TRUST UNITS

3.01 Trust Units

     The beneficial interests in the trust shall be divided into interests of one or more class, described and designated as Trust Units, which shall be entitled to the rights and subject to the limitations, restrictions and conditions set out herein and which may be represented by instalment receipts. Subject to subsection 104(7.1) of the Act, the Fund shall be entitled to issue Trust Units in different classes with each class having the rights, conditions and privileges attached thereto as determined by the Board of Directors of the Corporation at the time of issuance provided that the Fund shall have obtained such opinions or advice as the Board of Directors may consider appropriate from legal, accounting or investment advisors to the effect that the issuance of different classes of Trust Units will not materially adversely affect existing Unitholders nor adversely affect the application of the Amended Tax Ruling.

3.02 Limit of Issue

     The aggregate number of Trust Units which may be authorized and issued hereunder is limited to 500,000,000 Trust Units.

3.03 Form and Terms of Trust Units

a)	Trust Units are issuable only in fully registered form, evidencing Trust Units authorized pursuant to Section 3.02, shall forthwith be executed by the Corporation and delivered to the Trustee and shall thereupon be certified by and on behalf of the Trustee and shall be delivered by the Trustee to or upon the written order of the Corporation.
b)	Pursuant to the Agency Agreement, the Agents thereunder are to be appointed as the exclusive agents for the Corporation to solicit purchasers of the Trust Units. The Trust Units are to be offered for sale in those jurisdictions in Canada, or elsewhere, in which all legal requirements for the distributions of Trust Units have been fulfilled.

9

c)

The closing of the sale of Trust Units shall take place at the Time of Closing at the place or places stipulated in the Agency Agreement.

d)

The definitive form of the Trust Units and the certificate of the Trustee endorsed thereon shall be in the English language only, shall be in the form set forth in the Schedule hereto, shall be dated as of the Date of Closing (including all replacements issued in accordance with this indenture), shall include such distinguishing letters and numbers as the Corporation, with the approval of the Trustee, may prescribe, and shall be issuable in Unit denominations.

3.04 Ranking of Trust Units

     Each Trust Unit represents an equal fractional undivided beneficial interest in the Trust Fund provided however that the Board of Directors of the Corporation may cause the issuance of different classes of Trust Units and set priorities in respect of capital and income for such classes.

3.05 Trust Units Non-Assessable

     No Trust Units shall be issued other than as fully paid and non-assessable provided, however, that Trust Units may be issued and sold on an instalment basis, and in such case the Fund may take a security interest in any Trust Units so issued as security for unpaid instalments. No Person shall be entitled, as a matter of right, to subscribe for or purchase any Trust Unit except in accordance with the provisions hereof. There are no pre-emptive rights attaching to the Trust Units.

3.06 Fractional Trust Units

     Fractional Trust Units may be issued.

3.07 Legal Ownership of Assets of the Fund

     The legal ownership of the assets of the Fund and the right to manage the investments of the Fund are vested exclusively in the Trustee, and the Trust Unitholders shall have no interest therein other than the beneficial interest in the Trust Fund conferred by their Trust Units issued hereunder and they shall have no right to compel any partition, division, dividend or distribution of the Trust Fund or any of the assets of the Fund. The Trust Units shall be personal property and shall confer upon the holders thereof only the interest and rights specifically set forth in this Trust Indenture. No Trust Unitholder has or is deemed to have any right of ownership in any of the assets of the Fund.

3.08 Purchase of Initial Unit by Fund

     On the Original Date of Closing, the Fund will purchase the Initial Unit from the Corporation, and the Corporation shall sell the Initial Unit to the Fund, for a purchase price of ten dollars in lawful money of Canada and, upon the completion of such purchase and sale, the Initial Unit shall thereupon be canceled and shall be no longer outstanding for any of the purposes of this Indenture.

10

3.09 Transferability of Trust Units

     The Trust Units are transferable.

3.10 Rights, Warrants and Options

     The Trustee may create and issue rights, warrants or options to subscribe for Trust Units, which rights, warrants or options may be exercisable at such subscription price or prices and at such time or times as the Trustee may determine. Any rights, warrants or options so created may be issued for no consideration or for such consideration as the Trustee may determine. A right, warrant or option shall not be a Trust Unit and a holder thereof shall not be a Trust Unitholder.

3.11 Non-Resident Unitholders

     At no time may the Fund be established or maintained primarily for the benefit of nonresidents of Canada (“non-residents”) within the meaning of the Act. If at any time the Trustee becomes aware, as a result of requiring declarations as to beneficial ownership, that the beneficial owners of 49% of the Trust 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 Trust Units from or issue or register a transfer of Trust Units to a Person unless the Person provides a declaration that the Person is not a non-resident. If, notwithstanding the foregoing, the Trustee determines that a majority of the Trust Units are held by non-residents, the Trustee may send a notice to non-resident holders of Trust 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 Trust 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 Trust Units or provided the Trustee with satisfactory evidence that they are not non-residents, the Trustee may on behalf of such Unitholders sell such Trust Units and, in the interim, shall suspend the voting and distribution rights attached to such Trust Units. 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 and their rights shall be limited to receiving the net proceeds of sale upon surrender of the Certificates representing such Trust Units.

ARTICLE IV
INVESTMENTS OF TRUST FUND

DISTRIBUTIONS

5.01 Distributions

     Subject to Section 5.03, the Trustee shall distribute the Distributable Income on:

a)	the 15th day of each February, May, August and November in each year; or
b)	if so directed by the Board of Directors of the Corporation, on the 15th day of each calendar month;

to Trust Unitholders of record as of the close of business on the tenth Business Day preceding the then current distribution date (each, a “Record Date”) in accordance with the pro rata share of each Trust Unitholder (provided that the Trustee may deduct or withhold amounts required by law from any Trust Unitholders’ distributions). A Unitholder shall have the right to enforce the payment of its share of such distributions on any such distribution date.

5.02 Crown Obligations

     The Trustee shall be obligated to (i) apply for ARC, and (ii) reimburse the Corporation for Reimbursed Crown Charges paid by the Corporation except to the extent that the Corporation has elected to waive its right to reimbursement, in accordance with the Royalty Indenture.

5.03 Income of the Fund

     The Trustee shall not be required to distribute to Trust Unitholders any proceeds from the sale of the Royalty if the provisions of the Royalty Indenture provide that such proceeds may be applied to the purchase of the Royalty in respect of Replacement Properties. Any such proceeds received by the Trustee in a calendar year that are not expended on a Royalty in the calendar year shall be distributed on February 15 of the following year to Trust Unitholders of record as of the close of business on the fifth Business Day preceding such distribution date. The Trustee may in its discretion, but shall not be obligated to, distribute any such proceeds received or receivable,

12

on or prior to December 31 of the calendar year to the extent that such distribution is required to reduce the taxable income of the Fund to nil.

5.04 Method of Payment of Distributions

A distribution in respect of a Trust Unit shall be paid by cheque to the order of the Person in whose name the Trust Unit is registered and mailed by ordinary mail, postage prepaid to such Person at his last address appearing on the register of Trust Unitholders on the applicable Record Date. The forwarding of such cheque shall satisfy and discharge the liability for a distribution to the extent of the sums represented thereby (plus the amount of any tax deducted) unless such cheque shall not be paid on presentation; provided that if such cheque is not received by the registered Trust Unitholder, or is lost or destroyed, the Trustee (upon being furnished with reasonable evidence of such non-receipt, loss or destruction and indemnity reasonably satisfactory to it) shall issue or cause to be issued to such registered Trust Unitholder a replacement cheque in the same amount.

5.05 Distributions Deemed as to Net Income or Capital

     All distributions made in respect to Trust Units shall be deemed to be made first from the net income of the Trust, if any, as of the Record Date to which the distribution relates provided however that the directors of the Corporation may cause the issuance of Trust Units of different classes with different priorities as to the receipt of net income or capital from the Trust, subject to subsection 104(7.1) of the Act. The net income of the Trust or the repayment of capital from the Trust shall be allocated, as the case may be, for the purpose of the Act, to the Trust Unitholders of each class of Trust Units in accordance with the prorata share of each Trust Unitholder in the Trust in such class on the Record Date.

5.06 Obligations of Corporation

a)

On the dates in each year in which the Board of Directors of the Corporation elects to make Cash Distributions in accordance with section 1.01(j) of the Royalty Indenture, the Corporation will furnish or cause to be furnished to the Trustee and to the Royalty Unitholders or Trust Unitholders of record on the tenth business day immediately preceding each of such dates, on behalf of the Trustee, payment to each Trust Unitholder of his respective share of the Cash Distribution plus ARC, plus any interest earned by the Fund.

     Except as prohibited by law, the Trustee may grant or delegate to a Person or Persons (the “Manager” or “Administrator” as the case may be) 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 Indenture, without regard to whether such authority is normally granted or delegated by trustees. The Trustee may grant to the Manager or Administrator the broad discretion and authority to administer and regulate the day-to-day operations of the Fund, to act as agent for the Fund, to execute documents on behalf of the Trustee and to make decisions which conform to general policies and general principles established hereunder or previously established by the Trustee. The Trustee may enter into a contract or contracts with the Manager or Administrator relating to the Manager or Administrator’s authority, term of appointment, compensation and any other matters deemed desirable by the Trustee and the Corporation. The Corporation, the Trustee, Pengrowth Management Limited and the Fund shall enter into the Management Agreement pursuant to which Pengrowth Management Limited shall be appointed “Advisor” and assigned certain duties of the Manager.

10.02 The Corporation

     Pursuant to its ability to delegate in accordance with Section 10.01, the Trustee hereby delegates to the Corporation as administrator (the “Administrator”) responsibility for:

a) any and all matters relating to an offering of Trust Units to prospective Trust Unitholders including:

i) ensuring compliance with all applicable laws;

24

ii)	all matters relating to the content of any documents prepared and issued in respect of such offering, the accuracy of the disclosure contained therein, and the certification thereof;

iv)	all matters concerning any Underwriting Agreement providing for the sale of Trust Units or rights to acquire Units;

b)	any and all matters and decisions relating to the acquisition of facilities, interests or royalty interests or other assets by the Fund; and
c)	the determination of Distributable Income.

     The Corporation as Administrator 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 Fund 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 execute any agreements on behalf of the Fund as the Corporation shall have authorized within the scope of any authority delegated to it hereunder.

10.03 Power of Attorney

     Without limiting any of the other provisions of this Article X, the Trustee hereby delegates to the Corporation from time to time the full power and authority, and constitutes the Corporation its true and lawful attorney in fact, to sign on behalf of the Fund all prospectuses, annual information forms, management proxy circulars, other offering documents and any other documents ancillary or similar thereto required to be signed by the Fund from time to time.

10.04 Liability of Trustee

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

10.05 Performance of Obligations

     In the event that the Manager is unable or unwilling to perform its obligations under the Management Agreement, or there is no Manager, the Trustee shall either perform all obligations of the Manager thereunder or shall be entitled to engage another Person that is duly qualified to perform such obligations.

25

10.06 Certificate of Compliance

     The Corporation as Administrator shall, and shall cause the Manager to, furnish to the Trustee annually, within 120 days of the fiscal year end of the Fund, a certificate signed by the Chief Executive Officer and the Chief Financial Officer of the Administrator and Manager, or such other officers of the Administrator and the Manager as may be acceptable to the Trustee certifying that the Administrator and the Manager are in compliance in all material respects of its covenants, duties or obligations under the Trust Indenture and Royalty Agreements relating to the business and affairs of the Fund, or if such is not the case, specifying the covenants, duties or obligations which have not been complied with and giving particulars of such non compliance.

ARTICLE XI
AMENDMENT

11.01 Amendment

     The provisions of this Indenture except where specifically provided otherwise may only be amended by Extraordinary Resolution. Any of the provisions of this Indenture except where specifically provided otherwise may only be amended by the Trustee at any time or times, without the consent, approval or ratification of any of the Trust Unitholders or any other Person, for the purpose of:

a)	ensuring that the Fund will comply with any applicable laws or requirements of any governmental agency or authority of Canada or of any province;
b)	ensuring that the Fund will satisfy the provisions of each of subsections 108(2) and 132(6) of the Act;
c)	ensuring that such additional protection is provided for the interests of Trust Unitholders as the Trustee may consider expedient;
d)	removing any conflicts or inconsistencies between the provisions of this Indenture or any supplemental indenture and any prospectus filed with any regulatory or governmental body with respect to the Fund, or any applicable law or regulation of any jurisdiction, if, in the opinion of the Trustee, such an amendment will not be detrimental to the interests of the Trust Unitholders; or
e)	making any typographical or other non-substantive changes that Counsel may advise are necessary or desirable and which are not adverse to the interests of the Trustee or the Trust Unitholders for the purpose of curing or correcting any ambiguity or defective or inconsistent provisions or clerical omission, mistake or manifest error herein or in any supplemental indenture,

but notwithstanding the foregoing, no such amendment shall reduce the fractional undivided interest in the Trust Fund represented by any Trust Unit without the consent of the holder or such Trust Unit, and no amendment shall reduce the percentage of votes required to be cast at a

26

meeting of the Trust Unitholders for the purpose of this Section 11.01 without the consent of the holders of all of the Trust Units then outstanding.

11.02 Notification of Amendment

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

ARTICLE XII
MEETINGS OF TRUST UNITHOLDERS

12.01 Annual and Special Meetings of Trust Unitholders

     Annual meetings of the Trust Unitholders shall be held, commencing in 1990, 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 Trust Unitholders may be entitled to vote upon as hereinafter provided in this Article XII, or as the Trustee may determine. Special meetings of the Trust Unitholders may be called at any time by the Trust and shall be called by the Trustee upon a written request of Trust Unitholders holding in the aggregate not less than 5% of the Trust Units then outstanding, such request specifying the purpose or purposes for which such meeting is to be called. Meetings of Trust Unitholders shall be held in the City of Calgary, or at such other place within Alberta as the Trustee shall designate. To the extent permitted by applicable law, meetings of Trust Unitholders may be held partially or entirely by means of a telephonic, electronic or other communication facility, including teleconferencing, video conferencing, computer link, webcasting and other similar means. 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 Trust 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.

12.02 Notice of Meetings

     Notice of all meetings of Trust Unitholders shall be given by unregistered mail postage prepaid addressed to each Trust Unitholder at his registered address, mailed at least twenty one (21) days and not more than fifty (50) days before the meeting. Such notice shall set 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 Trust Unitholder to form a reasonable judgement thereon, together with the text of any resolution, at the time of mailing of the notice, proposed to be passed. Any adjourned meeting may be held as adjourned without further notice. The accidental omission to give notice or the non-receipt of such notice by a Trust Unitholder shall not invalidate any resolution passed at any such meeting. Notwithstanding the foregoing, a meeting of Trust Unitholders may be held at any time without notice if all the Trust Unitholders are present or represented thereat or those not so present or represented have waived notice. Any Trust Unitholders (or a duly appointed proxy of a Trust Unitholder) may waive any notice required to be given under the provisions of this paragraph,

27

and such waiver, whether given before or after the meeting, shall cure any default in the giving of such notice.

12.03 Quorum

     At any meeting of the Trust Unitholders, subject as hereinafter provided, a quorum shall consist of two or more individuals present in person either holding personally or representing as proxies not less than 5% of the outstanding Trust Units. In the event of such quorum not being present at the appointed place on the date for which the meeting is called within one half (1/2) hour after the time fixed for the holding of such meeting, the meeting shall stand adjourned to such day being not less 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 Trust 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.

12.04 Voting Rights of Trust Unitholders

     Only Trust Unitholders of record shall be entitled to vote and each Trust Unit shall entitle the holder or holders of that Trust Unit to one vote at any meeting of Trust Unitholders. At any meeting of Trust Unitholders, any holder of Trust Units entitled to vote thereat may vote by proxy and a proxy need not be a Trust 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 twenty-four 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 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, such vote purporting to be executed by or on behalf of a Trust Unitholder shall be deemed valid unless challenged at or prior to its exercise, and the burden of proving invalidity shall rest on the challenger. To the extent permitted by applicable law, the Trustee may from time to time make, vary or revoke such regulations as it shall think fit providing for and governing the depositing and tabulation of proxies by telephonic, electronic or other communication means. To the extent permitted by applicable law, a person entitled to vote at a meeting of Trust Unitholders may vote by means of a telephonic, electronic or other communication facility that the Trustee has made available for that purpose.

12.05 Resolutions Binding the Trustee

     Trust Unitholders shall be entitled to pass resolutions that will bind the Trustee only with respect to the following matters:

a)	the removal or appointment of the Trustee as provided in Section 8.03 or 8.04;
b)	approval of a change of auditors as provided in Section 17.03;

g)	the sale of the property of the Trust Fund as an entirety or substantially as an entirety;
h)	authorizing and directing the Trustee to commence, defend, adjust or settle suits or legal proceedings in connection with the Fund and to represent the Fund in any such suits or legal proceedings (provided that the Trustee shall be obliged to comply with such authority and requirements only in the event that the Trustee has been provided with reasonable security for the payment of all costs which may be incurred in connection therewith); and
i)	authorizing and directing the Trustee to subordinate its rights to receive Royalty Income and all other sums and to distribute Distributable Income in circumstances where a default by the Corporation has occurred in respect of any of its obligations to pay any of the Corporation’s lenders, including a default in connection with any credit facility or in connection with any swap or hedging agreement, or to guarantee all or any of the obligations, liabilities or indebtedness of the Corporation to all or any of the Corporation’s lenders, including without limitation in respect of all or any of the obligations, liabilities and indebtedness of the Corporation to any or all of such lenders under, pursuant or relating to any credit facility, swap or hedging agreement or otherwise, or to any other Person or Persons.

     Except with respect to the above matters set out in this Section 12.05 no action taken by the Trust Unitholders or resolution of the Trust Unitholders at any meeting shall in any way bind the Trustee. Actions taken or resolutions passed in respect of matters described in subsection (a), (d), (e), (f), (g), (h) and (i) shall be by Extraordinary Resolution. Any other action taken or resolution passed in respect of any matter at a meeting of Trust Unitholders shall be by Ordinary Resolution unless the contrary is otherwise expressly provided under any specific provision of this Indenture.

12.06 Meaning of “Extraordinary Resolution” and “Ordinary Resolution”

a)

The expression “Extraordinary Resolution” when used in this indenture means, subject as hereinafter in this Article provided, a resolution proposed to be passed as an extraordinary resolution at a meeting of Trust 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 5% 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.

b)

The expression “Ordinary Resolution” when used in this indenture means, subject as hereinafter in this Article provided, a resolution proposed to be passed as an ordinary

29

c)	If, at any such meeting, the holders of 5% of the aggregate number of Trust Units outstanding are not present in person or by proxy within 30 minutes after the time appointed for the meeting, then the meeting, if convened by or on the requisition of Trust 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.

In the event that the Trustee does not fix a record date for any meeting of Trust Unitholders, the record date for such meeting shall be the date upon which notice of the meeting is given as provided under Section 12.02.

12.08 Appointment of Inspector

     The Trustee shall call a meeting of Trust Unitholders upon the written request of Trust unitholders holding in the aggregate not less than 5% of the Trust Units then outstanding for the purpose of considering the appointment of an Inspector to investigate the performance by the

f)	“For information as to personal liability of a Trust Unitholder, see the reverse side of this certificate.” or words of like effect.

     Until otherwise determined by the Trustee, each such certificate shall legibly set forth on the face or the reverse side thereof, inter alia, the following:

a)

“The Trust Indenture provides that no Trust Unitholder shall be subject to any personal liability whatsoever, in tort, contract or otherwise, to any person m connection with Fund property or the obligations or the affairs of the Fund and all such persons shall look solely to the Fund property for satisfaction of claims of any nature arising out of or in connection therewith and the Fund property only shall be subject to levy or execution.” or words of like effect;

     A register shall be kept at the principal corporate trust office of the Trustee, which register shall contain the names and addresses of the Trust Unitholders, the respective numbers of Trust Units held by them, the certificate numbers of the certificates representing such Trust Units and a record of all redemptions thereof.

The Trustee shall have the right to treat the Person registered as a Trust Unitholder on the register of the Fund as the owner of such Trust Units for all purposes, including, without limitation, payment of any distribution, giving notice to Trust Unitholders and determining the right to attend and vote at meetings of Trust Unitholders.

13.05 Successors of Trust Unitholders

     Any Person becoming entitled to any Trust Units shall be recorded as the holder of such Trust Units and shall receive a new certificate therefore upon production of evidence satisfactory to the Trustee thereof and delivery of the existing certificate to the Trustee, but until such record

32

is made the Trust 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.

13.06 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 Fund, 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 Trust Units; provided, however, that any Person recorded as a Trust 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.

13.07 Performance of Trust

     The Trustee, the Trust 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 Trust 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 Trust Unitholder.

13.08 Lost Certificates

     In the event that any certificate for Trust Units is lost, stolen, destroyed or mutilated, the Trustee may authorize the issuances of a new certificate for the same number of Trust 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 may require the applicant to supply to the Fund 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.

33

13.09 Death of a Trust Unitholder

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

13.10 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.

14.04 Powers of the Trustee upon Termination

     After the date referred to in Section 14.01 or the date on which a resolution has been approved under Section 14.02, the Trustee shall carry on no activities except for the purpose of winding up the affairs of the Fund as hereinafter provided and, for this purpose, the Trustee shall continue to be vested with and may exercise all or any of the powers conferred upon the Trustee under this Indenture.

14.05 Sale of Investments

     After the date referred to in Section 14.04, the Trustee shall proceed to wind up the affairs of the Fund as soon as may be reasonably practicable and for such purpose shall sell and convert into money all investments and other assets comprising the Trust Fund in one transaction or in a series of transactions at public or private sale and do all other acts appropriate to liquidate the Trust Fund.

     If the Trustee is unable to sell all or any of the Royalty Units which comprise part of the Trust Fund by the date set for termination as set out herein, the Trustee may distribute the remaining Royalty Units directly to the Trust Unitholders on the same basis as the Royalty Units were acquired by the Trust Fund on behalf of the Trust Units.

a)

the Trustee shall allocate to each Trust Unitholder and each Trust Unitholder shall thereupon be entitled to enforce payment of his pro rata share of such part of all amounts that would otherwise be included in computing income of the Fund for the purposes of the Income Tax Act for the year and that are not payable to Trust Unitholders in the year by virtue of any provision of this Trust Indenture other than this Section 14.06;

b)

the remaining part, if any, of the said proceeds, other assets and cash shall be distributed among the Trust Unitholders in accordance with their pro rata shares.

35

14.07 Redemption and Termination by Other Disposition

If the balance of the other investments or assets comprising the Trust Fund are sold or otherwise disposed of, the Trustee will distribute to the Trust Unitholders on a pro rata basis the net proceeds from such disposition and the Fund shall terminate.

14.08 Further Notice to Trust Unitholders

     In the event that all of the Trust Unitholders shall not surrender their Trust Units for cancellation within six (6) months after the time specified in the notice or resolution referred to in Section 14.03 the Trustee shall give further notice to the remaining Trust Unitholders to surrender their Trust Units for cancellation and, if within one year after the further notice, all the Trust Units shall not have been surrendered for cancellation, such remaining Trust Units shall be deemed to be cancelled without prejudice to the rights of the holders of such Trust Units to receive their pro rata shares of the amounts referred to in Section 14.06 and the Trustee may either take appropriate steps, or appoint an agent to take appropriate steps, to contact such Trust Unitholders (deducting all expenses thereby incurred from the amounts to which such Trust Unitholders are entitled as aforesaid) or, in the discretion of the Trustee, may pay such amounts into court.
