h)	Notwithstanding anything herein to the contrary, it is understood and agreed that the Grantor shall be entitled to use, free from the obligation to pay the Royalty, such portion of the Petroleum Substances or any of them produced from the Properties as may be required to carry on drilling, producing or any other operations on the Properties related to the production of Petroleum Substances.

2.02	Operations
a)	As between the Grantor and the Royalty Unitholders, the Grantor shall have the sole and exclusive control and management of the exploration, development and operation of the Properties including the right to elect to go to “non-consent” or “sole risk” on any operations and sole and exclusive right to bring, defend, settle, compromise or proceed with any claims or actions pertaining to the Properties, the operations conducted thereon or the production and sale of Petroleum Substances produced therefrom.
b)	The Grantor shall cause, insofar as it is able, all operations on the Properties to be conducted in a good and workmanlike manner, with capable and sufficient personnel and in accordance with good oilfield and engineering practice and all applicable legislation.
c)	The Grantor shall cause, insofar as it is unable to market the disposition of Petroleum Substances itself, a third party operator to carry out all marketing services for the disposition of Petroleum Substances which may be produced from the Properties, and to service all existing sales contracts and provide for the delivery of products sold thereunder.
d)	As between the Grantor and the Royalty Unitholders, the Grantor shall make all operating decisions with respect to the Properties including, without limitation, the shutting-in and abandonment of wells and the election to convert any gross overriding royalty interests to working interests.
e)	The Grantor shall indemnify and keep indemnified the Royalty Unitholders and the Grantee from and against all actions, suits, claims and demands whatsoever by any Person or Persons whomsoever, in respect of any loss, injury, damage or obligation to compensate arising out of or connected with any of the operations of the Grantor or any of its Affiliates, or any third party retained by the Grantor to carry out such operations conducted on the Properties, or resulting from any breach by the Grantor of any of the covenants and agreements agreed to be performed by it hereunder.
f)	The Grantor, as owner of the Properties subject to the Royalty, shall have complete discretion as to the terms, conditions and length of all contracts entered into for the sale of production from the Properties including the sale of production on a discount contract basis and the Grantor shall not be responsible for any loss or alleged loss which may occur or be claimed by reason of any change in economic or political circumstances or otherwise with respect to any sales contract, as long as it is made in good faith. The Grantor shall take all reasonable and necessary steps to obtain all amounts receivable for production of Petroleum Substances from the Properties and may allow any discounts for prompt payment as are normal in the industry. The Grantor is not a guarantor of payment for any production sold to any third party, however, the Grantor shall diligently pursue the collection of any outstanding amount receivable with respect to production revenues.
g)	The Grantor shall have the right and power, at its option, to unitize, pool or combine the Properties or any portion or portions thereof, as to Petroleum Substances or any one or more of them, with other lands or leases covering lands in the same general area as the

- 16 -

	Properties, regardless of the ownership thereof, so as to create one or more unitized areas to be developed and operated as though such lands constituted a single petroleum, natural gas or mineral lease, licence or permit and to alter, amend, extend, cancel or rescind any such pooling or unit agreement. The basis and manner of such pooling or unitization, the manner of allotting unitized production among tracts of land and the content of any such agreement shall be in the Grantor’s sole discretion exercised bona fide and when so determined shall be binding upon the Royalty Unitholders. The units formed by such pooling, unitization, or combining as to any specific substance or substances, or from any specific stratum, need not conform in size or area with the unit or units into which all or any portions of the Properties is pooled, unitized, or combined as to any other stratum. The pooling, unitizing, or combining in one or more instances shall not exhaust the rights of the Grantor hereunder to pool, unitize, or combine the subject Property, or portions thereof, into other units. Upon any such pooling or unitization, the Royalty shall be calculated on the Royalty Income allocated to that portion of the Properties included in the pooled or unitized lands from time to time.
h)	The Grantor shall have the right and authority to join with any party or parties in an agreement or agreements providing for the operation of the Properties or any part thereof jointly with such other party or parties, and to permit such other party to become operator of the Properties or any part thereof.
i)	Subject to the provisions of this indenture, all Special Distributions and all Gross Revenue received by the Grantor net of any sums due to the Grantor pursuant hereto (except money received for Tangibles and unitization and pooling equalization payments relating to Tangibles) shall constitute trust funds in the hands of the Grantor and shall be received by the Grantor in trust for the Royalty Unitholders.
j)	The Grantor shall operate and maintain a separate account on behalf of the Royalty Unitholders and shall cause all Special Distributions and all Gross Revenue received to be paid into such separate account. The Grantor shall not commingle with its own funds, or any other funds, the Gross Revenue which it receives and holds for the Royalty Unitholders pursuant to this Agreement. The Grantor shall only be entitled to pay out of such separate account the Operating Costs, General and Administrative Costs, Management Fees, Debt Service Charges, Cash Distributions and taxes or other charges attributable to the Properties or the Grantor’s ownership of them.
k)	Notwithstanding anything herein to the contrary, the Royalty Unitholders shall not have access to the operations being conducted upon the Properties without obtaining the prior written consent of the Grantor.
l)	Notwithstanding anything herein to the contrary, the Grantor shall not be required to pay any income taxes accruing to the Trustee, the Fund or the Royalty Unitholders with respect to proceeds received pursuant to the Royalty.
m)	The Grantor shall carry and, insofar as it is able, shall cause all third party operators to carry such public liability and property damage insurance against hazards customarily insured against by prudent operators, other than those who self-insure, in operating

- 17 -

	similar properties and to use the proceeds of such insurance to repair or replace any damage insured against.
n)	The Grantor shall use its best reasonable efforts to ensure that the Properties are being produced and maintained in accordance with good industry practice, it being acknowledged that such covenant does not obligate the Grantor to develop the Properties or any part thereof or to produce the Petroleum Substances which may be within, upon or under the Properties.
o)	The Grantor shall approve and fund Capital Expenditures if they are intended to maintain or improve production from the Properties or if they are of the class of Capital Expenditures which are approved from time to time by the Board of Directors of the Grantor. Exploration drilling will not be funded unless approved by a resolution of the Board of Directors of the Grantor, except where such funding is required because the Properties are part of a unitized pool and the Capital Expenditures have been approved by a majority of the unitized pool participants. Capital Expenditures may be financed by payments from the Reserve or from Gross Revenue (and therefore deducted in the computation of Royalty Income as contemplated in the definition thereof), bank borrowings, farm-outs and the issuance of Royalty Units, or any of them.

2.03 Drilling and Other Credits

     The Grantor shall be entitled to one hundred (100%) per cent of all Drilling Credits other than those which are received in cash and the Grantor shall, to the extent possible, apply such non-cash Drilling Credits to Capital Expenditures or to reduce other expenses relating to the Properties. Any unitization or pooling equalization payments for Tangibles shall be the sole and exclusive property of the Grantor free and clear of any right or entitlement of the Royalty Unitholders.

2.04	Books and Records
a)	The Grantor shall at all times keep and maintain or cause to be kept and maintained by third party operators in the Province of Alberta or in the province in which the Properties are located true and accurate books, records and accounts showing the development and progress made, drilling done, other operations carried out, the quantities of Petroleum Substances produced from or allocated to the Properties and the disposition thereof.
b)	On the dates in each year in which the Board of Directors of the Grantor elects to make Cash Distributions in accordance with subsection 1.01(j) of this indenture, the Grantor 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, payment to each Royalty Unitholder of his respective share of the Cash Distribution. Notwithstanding the Cash Distribution dates selected by the Board of Directors, the Grantor will not later than 60 days following the end of each calendar quarter furnish or cause to be furnished to the Trustee and to the Royalty Unitholders of record on the tenth Business Day immediately preceding the 15th day of February, May, August and November of each year unaudited statements properly verified by an officer

- 18 -

	of the Grantor showing the quantity and kind of Petroleum Substances produced, saved and marketed from the Properties or in reference to which Royalty is computed and the calculation of Royalty Income and Reimbursed Crown Charges for the immediately preceding quarter.
c)	The Grantor will forward to the Trustee and to the Unitholders who have received Cash Distributions during the preceding calendar year, on a calendar year and cash basis, such income tax information (including information regarding ARC) as may be reasonably necessary in respect of the Royalty and the filing of Unitholders’ income tax returns.
d)	The Grantor will forward to Royalty Unitholders, upon request, any information required for the purpose of claiming monthly installments of ARC.

2.05 Commingling Production

     The Grantor shall have the right to commingle Petroleum Substances produced from the Properties with petroleum substances produced from other properties provided methods normally acceptable to the Crown in the right of the province or area of production are adopted to determine the proper measurement of individual well production. In the absence of any such governmental methods, segregated production tests of individual wells at intervals not greater than two months will be deemed to be an acceptable method.

2.06	Disposition, Assignments and Acquisitions
a)	The Royalty Unitholders may assign, sell or dispose of all or an undivided interest in the Royalty provided that such assignment, sale or disposition is a disposition of an entire Royalty Unit.
b)	The Grantor shall be entitled to make farmouts or other similar dispositions of specific interests in any part of the Properties provided that:

i)	the Royalty shall, upon the farmee or other participant earning its interest pursuant to the farmout or other disposition, burden only the interest, right, or estate retained, from time to time by or reserved to the Grantor; and
ii)	the prior approval of the Trustee as agent for the Unitholders is obtained prior to the farmout or other disposition.

c) The Grantor shall regularly monitor the performance of the Properties to ensure that they remain suitable for investment objectives of the Unitholders. In the event that the Grantor determines that the sale of all or part of the Properties and the sale of the Royalty attached thereto are in the best interest of the Unitholders, then:

i) if the Properties constitute non-core Properties of the Grantor, in the discretion of the Grantor, and in the aggregate in any given year total less than 25% of the assets held by the Grantor determined as at the date of any disposition of such Properties, based upon an independent engineering appraisal using a 15%

- 19 -

	discount rate and escalating prices, the Grantor may complete such sale or sales without the requirement of approval of the Unitholders;
ii)	or in any other case the Grantor may recommend the sale of such Properties and the Royalty, provided that such sale is approved by an Extraordinary Resolution of the Unitholders at a meeting of the Unitholders;

Upon such sale, the Royalties shall merge with the interest of the Grantor sold in the property. The Corporation may in its sole and absolute discretion distribute all or any of the net proceeds from the sale of Properties as a Special Distribution or to acquire Replacement Properties. Replacement Properties acquired shall immediately become Properties subject to all the terms and conditions of the Agreement.

d)	The Grantor may in the ordinary course of business and acting in a prudent manner consistent with the terms of this Agreement surrender, abandon or let expire such Properties or any part thereof and thereafter the Royalty shall terminate and be at an end in respect of such surrender, abandonment or expiry.
e)	Any proceeds from the sale of the Properties and the Royalty relating to the Properties, whether upon the termination of this Agreement or otherwise, shall be allocated as to 1% to the Grantor’s residual interest in the Properties and as to 99% to the Royalty thereon.
f)	The Grantor shall be entitled to acquire Canadian Resource Properties from time to time which in its discretion are suitable for the investment objectives of the Unitholders as determined by the Grantor. Such Canadian Resource Properties shall be subject to the Royalty and the terms of this Royalty Indenture upon the acquisition of such Canadian Resource Properties. The acquisition of Canadian Resource Properties may be financed in any manner that the Corporation sees fit in its sole discretion, including without limitation through proceeds from the sale of Properties, borrowings from the Fund and other lenders and the issuance of Royalty Units, Exchangeable Shares, notes, debentures and other securities and instruments.
g)	In the event that any bank or other lender to the Grantor, or any Person to whom the Grantor owes obligations in connection with swap or hedging obligations, realizes against assets (including, without limitation, Properties) in connection with collecting upon any of the obligations owing by the Grantor to any such bank, other lender or Person owed swap or hedging obligations, whether pursuant to any security granted by the Grantor or otherwise, upon any sale conducted in connection with such realization process the Royalty with respect to such assets shall merge with the interest of the Grantor sold in such assets and such assets may be sold free and clear of any remaining obligations to Unitholders with respect to the Royalty and the Royalty Unitholders agree to release the Royalty insofar as it relates the assets realized upon.

2.07 Lesser Interest

     The Royalty is calculated on only the share of production of Petroleum Substances and royalty income and net profits interests income to which the Grantor is entitled from or in respect

- 20 -

of the Properties. The Grantor will, in most instances, be entitled to the production from or income in respect of less than an undivided 100% interest in the petroleum and natural gas rights.

2.08	Conflicts of Interest
a)	There may be situations in which the interests of the Corporation will conflict with those of Unitholders. In addition, the Corporation may acquire oil and gas properties for its own account or on behalf of other entities. The Corporation will manage and administer such additional securities and properties, as well as enter into other types of energy-related management and advisory activities. Thus the Corporation and its management will not carry on full time its activities on behalf of Unitholders and, when acting on behalf of others, may at times act in contradiction or competition with the interests of Unitholders.
b)	In resolving such conflicts, decisions will be made on a basis consistent with the objectives and funds of each group of interested parties and time limitations on investment of such funds, all consistent with the duty of the Corporation to deal fairly and in good faith with each such group of persons. In the event that the interests of the Corporation are in conflict with those of Unitholders, the Corporation shall make decisions acting in good faith, having regard to the best interests of Unitholders and in a manner that would not contravene their fiduciary obligations to Unitholders.
c)	Canadian Resource Properties will not be acquired from officers or directors of the Grantor or Pengrowth or Persons not at arm’s length (as defined in section 251 of the Act) with such persons at prices which are greater than fair market value as established by an opinion of an independent financial advisor nor will Properties be sold to officers or directors of the Grantor or Pengrowth or Persons not at arm’s length with such persons at prices which are less than fair market value as established by an opinion of an independent financial advisor.

2.09 Force Majeure

     No party shall be deemed to be in default in respect of non-performance of its obligations hereunder, if any, so long as its non-performance is due to strike, lockout, industrial disturbance, storm, fire, flood, explosion, lightning, tempest, act of God or Queen’s enemies, governmental restraint, or any other cause (whether similar or dissimilar to those enumerated) beyond its control; provided that lack of finances shall in no event be deemed to be a cause beyond a party’s control; provided further that in the case of any obligations contained in any of the Leases, the rights of any of the parties hereto with respect to force majeure shall not exceed those granted to a party pursuant to the leases.

2.10	Rights and Remedies of the Unitholders
a)	The parties hereto acknowledge and agree that the Trustee, who shall incur no liabilities hereunder to any Unitholders, shall be entitled to the benefits of and to enforce all of the provisions of this Agreement against the Grantor for and on behalf of the Unitholders.

- 21 -

b) The Unitholders shall not be entitled to directly enforce the benefits and obligations of this Agreement except as specifically provided in the Royalty Indenture and Trust Indenture.

2.11 Term of the Royalty

     Except as otherwise herein provided, the Royalty shall continue in full force and effect until:

a)	there are no longer any Properties; and
b)	final settlement is made between the parties hereto in liquidating all outstanding accounts in accordance with this Agreement.

3.04 Signing of Royalty Unit Certificate

     The Royalty Unit Certificates shall be signed under seal of the Corporation (or a facsimile or reproduction thereof which shall be deemed to be the seal of the Corporation) by any two of the President, a Vice-President, and the Secretary of the Corporation.

Upon a Royalty Unitholder exercising this option, the Corporation’s interest in the Properties shall be adjusted as may be necessary to ensure continued compliance with the true intent of this indenture and the Prospectus.

5.02	Exercise of Conversion Right
a)	For the purposes of this Article, Royalty Units shall be deemed to be surrendered for conversion on the date (herein called the “Date of Conversion”) on which they are so surrendered in accordance with the provisions of this Article and, in the case of Royalty Units surrendered by post or other means of transmission on the date on which they are received by the Trustee at one of its offices specified in subsection 5.02(b); provided that if Royalty Units are surrendered for conversion on a day which is not a Business Day, the Person or Persons entitled to receive an undivided interest in the Properties shall become the beneficial owner of such interest as at the date on which such registers are next re-opened.

     No Unitholder shall be held to have any personal liability as such, and no resort shall be had to his property or assets for satisfaction of any obligation or claim arising out of or in connection with any contract or obligation of the Corporation, the Fund or of the Trustee or any obligation for which a Unitholder would otherwise have to indemnify the Trustee or for any liability incurred by the Trustee as such, but rather the Properties (and indirectly the Royalty) only are intended to be liable and subject to levy or execution for such satisfaction. Further, the

- 30 -

6.06 Performance of Covenants by the Corporation

     If the Corporation shall fail to perform any of its covenants contained in this indenture, the Trustee may notify the Unitholders of such failure on the part of the Corporation or may, in its discretion, perform any of the said covenants capable of being performed by it, but shall be under no obligation to perform said covenants or to notify the Unitholders of such performance by it. All sums expended by the Trustee in so doing shall be repayable as provided in Section 6.05. No such performance or expenditure by the Trustee shall relieve the Corporation of any default hereunder or of its continuing obligations under the covenants herein contained. Notwithstanding the foregoing, the Trustee shall not borrow money, guarantee obligations or pledge property pursuant hereto.

The accidental omission to give notice of a meeting to any Royalty Unitholder shall not invalidate any resolution passed at any such meeting.

- 32 -

8.03 Chairman

     An individual (who need not be a Royalty Unitholder) designated in writing by the Trustee shall be chairman of the meeting and if no individual is so designated, or if the individual so designated is not present within 15 minutes from the time fixed for the holding of the meeting, the Royalty Unitholders present in person or by proxy shall choose some individual present to be chairman.

8.06 Show of Hands

     Every question submitted to a meeting shall be decided in the first place by a majority of the votes given on a show of hands except that votes on an Extraordinary Resolution shall be given in the manner hereinafter provided.

A registered holder of a Royalty Unit, any one of them present in person or by proxy at the meeting may vote in the absence of other or others; but in case more than one of them be present in person or by proxy, only one of them may vote in respect of the Royalty Units of which they are the joint registered holders. The chairman of any meeting shall be entitled, both on a show of hands and on a poll, to vote in respect of the Royalty Units, if any, held or represented by him.

e)	the depositing and tabulation of proxies by telephonic, electronic or other communication means; and
f)	generally for the calling of the meetings of Royalty Unitholders and the conduct of business thereat.

CONCERNING THE TRUSTEE

11.01	Rights and Duties of Trustee
a)	In the exercise of the rights and duties prescribed or conferred by the terms of this indenture, the Trustee shall exercise the degree of care, diligence and skill that a reasonably prudent trustee would exercise in comparable circumstances and shall act honestly and in good faith with a view to the best interest of the Unitholders. No provision of this indenture shall be construed to relieve the Trustee from liability for its own negligent action, its own negligent failure to act, its own willful misconduct or bad faith, or its disregard of its obligations and duties or in any case where the Trustee fails to act honestly, in good faith and in the best interests of the Unitholders, with that degree of care, diligence and skill that a reasonably prudent trustee would exercise in comparable circumstances.
b)	The obligation of the Trustee to commence or continue any act, action or proceeding for the purpose of enforcing any rights of the Trustee or the Unitholders hereunder shall be conditional upon the Unitholders furnishing, when required by notice by the Trustee, sufficient funds to commence or to continue such act, action or proceeding and indemnity reasonably satisfactory to the Trustee against the costs, charges and expenses and liabilities to be incurred thereby and any loss and damage it may suffer by reason thereof. None of the provisions contained in this indenture shall require the Trustee to expend or to risk its own funds or otherwise to incur financial liability in the performance of any of its duties or in the exercise of any of its rights or powers unless indemnified as aforesaid.
c)	The Trustee may, before commencing or at anytime during the continuance of any such act, action or proceeding, require the Unitholders, at whose instance it is acting, to deposit with the Trustee the Units held by them, for which Units the Trustee shall issue receipts.
d)	Every provision of this indenture that by its terms relieves the Trustee of liability or entitles it to rely upon any evidence submitted to it is subject to the provisions of this Section 11.01 and of Section 11.02.

- 41 -

e)	The Trustee shall not borrow money on behalf of the Unitholders, guarantee the obligations of the Unitholders or pledge any property of the Unitholders.

c)	Whenever it is provided in this indenture that the Corporation shall deposit with the Trustee resolutions, certificates, reports, opinions, requests, orders or other documents, it is intended that the truth, accuracy and good faith on the effective date thereof and the facts and opinions stated in all such documents so deposited shall, in each and every such case, be conditions precedent to the right of the Corporation to have the Trustee take the action to be based thereon.
d)	Proof of the execution of an instrument in writing by any Unitholder may be made by the certificate of a notary public, or other officer with similar powers, that the person signing such instrument acknowledged to him the execution thereof, or by an affidavit of a witness to such execution or in any other manner which the Trustee may consider adequate.
e)	The Trustee may employ or retain such Counsel, accountants, appraisers or other experts or advisors as it may reasonably require for the purpose of discharging its duties hereunder and may pay reasonable remuneration for all services so performed by any of them, without taxation of costs of any Counsel, and shall not be responsible for any misconduct or negligence on the part of any such experts or advisors who have been appointed with due care by the Trustee.

The Unitholders by Extraordinary Resolution shall have power at any time to remove the existing Trustee and to appoint a new trustee. In the event of the Trustee resigning or being removed as aforesaid or being dissolved, becoming bankrupt, going into liquidation or otherwise becoming incapable of acting hereunder, the Corporation shall forthwith appoint a new trustee unless a new trustee has already been appointed by the Unitholders; failing such appointment by the Corporation, the retiring Trustee or any Unitholder may apply to a justice of the Court of Queen’s Bench of Alberta, on such notice as such justice may direct, for the appointment of a new trustee; but any new trustee so appointed by the Corporation or by the Court shall be subject to removal as aforesaid by the Unitholders.

b)	Upon the appointment of a successor trustee, the Corporation shall promptly notify the Unitholders thereof in the manner provided for in Article Eleven hereof.
c)	Any corporation into or with which the Trustee may be merged or consolidated or amalgamated, or any corporation resulting therefrom to which the Trustee shall be a party, or any corporation succeeding to the trust business of the Trustee shall be the successor to the Trustee hereunder without any further act on its part or any of the parties hereto, provided that such corporation would be eligible for appointment as a successor trustee under subsection 11.07(a) above.
d)	Any Royalty Unit Certificates certified but not delivered by a predecessor trustee may be certified by the successor trustee in the name of the predecessor or successor trustee.

a)	The Trustee represents to the Corporation that at the time of execution and delivery hereof no material conflict of interest exists between its role as a trustee hereunder and its role in any other capacity and agrees that in the event of a material conflict of interest arising hereafter it will, within 90 days after ascertaining that it has such material conflict of interest, either eliminate the same or assign its trust hereunder to a successor trustee approved by the Corporation and meeting the requirements set forth in subsection 11.07(a). If any such material conflict of interest exists or hereafter shall exist, the

- 44 -

	validity and enforceability of this indenture and the Royalty Unit Certificates shall not be affected in any manner whatsoever by reason thereof.

The Grantor will not use the Reserve for any other purposes.

13.04 Termination of Reserve

          When there are no Canadian Resource Properties subject to the Royalty, amounts deposited into the Reserve that can reasonably be attributed to Other Revenues will be used to repay principal and interest in respect of indebtedness borrowed or incurred to acquire Other Investments and any excess will be paid to the Grantor. The remaining amounts in the Reserve will be used to pay, in the following order: (i) Debt Service Charges; (ii) Operating Costs and Reclamation Obligations and (iii) General and Administrative Costs and Management Fees.

          Subject to the terms of the Credit Facility, if changes are made to the Act so as to permit the formation of a vehicle such as a trust which is similar to a “qualifying environmental trust” (as defined in the Act in effect on the date hereof) to secure or otherwise provide funding for Reclamation Obligations relating to the Properties which would have beneficial income tax consequences for the Grantor in the reasonable opinion of the Grantor:

a) the Grantor shall establish such a vehicle;

- 47 -

b)	the amount then contained in the Reserve to fund Reclamation Obligations shall be paid to such vehicle;
c)	thereafter, amounts which would otherwise have been paid into the Reserve in respect of Reclamation Obligations will, instead, be paid to such vehicle; and
d)	thereafter, for the purposes of computing Operating Costs and Royalty Income, payments to or from such vehicle shall be deemed to be payments to or from the Reserve.
