2

3

(4) the discounted future net revenues, calculated in accordance with Applicable Securities Legislation, attributable to reserves subject to Dollar-Denominated Production Payments that, based on the estimates of production and price assumptions included in determining the discounted future net revenues specified in the first clause (1) above, would be necessary to fully satisfy the payment obligations of the Corporation and its Restricted Subsidiaries with respect to Dollar-Denominated Production Payments on the schedules specified with respect thereto.

“Canada Yield Price” means the price for the Notes, as determined by an independent investment dealer selected by the Corporation and acceptable to the Trustee, acting reasonably, as of the Business Day immediately preceding the day on which the notice of redemption for prepayment is given, equal to the greater of: (i) 101% of the principal amount of the Notes; and (ii) the sum of the present values of (a) the redemption price of such Notes as of December 3, 2027 as described under Section 4.1 plus (b) the scheduled payments of interest on the Notes remaining from the Redemption Date up to and including December 3, 2027 (not including any portion of the scheduled payments of interest accrued as of the relevant Redemption Date) discounted to the relevant Redemption Date on a semi-annual basis (assuming a 365-day year) at the discount rate equal to the sum of the Canada Bond Yield for such Notes and the Canada Yield Spread.

“Capital Stock” means:

(1) in the case of a corporation, association or other business entity, any and all shares, interests, participations, rights or other equivalents (however designated and whether or not voting) of corporate stock;

The Corporation’s and the Guarantors’ obligations to any Holder will, notwithstanding any judgment in a currency (the “judgment currency”) other than Canadian dollars, be discharged only to the extent that on the Business Day following receipt by such Holder or the Trustee, as the case may be, of any amount in such judgment currency, such Holder may in accordance with normal banking procedures purchase Canadian dollars with the judgment currency.

Article 2
THE NOTES

2.1 Issue and Designation of Notes

In accordance with this Indenture, the Corporation is authorized to issue a series of Notes designated as “8.125% Senior Unsecured Notes due December 3, 2030”. The Notes will be issued in denomination of $2,000 and integral multiples of $1,000 in excess thereof. The Notes will become due and payable, together with accrued and unpaid interest thereon, on December 3, 2030.

2.2 Additional Notes

The aggregate principal amount of Notes which may be issued under this Indenture on the Issue Date is $175,000,000. The Corporation shall be entitled, subject to Section 5.11, to issue Additional Notes and Other Notes in an unlimited principal amount under this Indenture from time to time. The Additional Notes shall have identical terms as the Notes issued on the Issue Date, other than with respect to the date of issuance, issue price and the first Interest Payment Date, and which shall bear the same designation and designating letters as those applied to such previous issue and will be numbered consecutively upwards in respect of such denominations of Notes in like manner and following the numbers of the Notes of such previous issue. The Other Notes may be issued in one or more series with a Stated Maturity and coupon different to that applicable to the Notes and any Additional Notes and terms fixed in each case at the time of issuance. The Notes issued on the date hereof and any Additional Notes shall be treated as a single series for all purposes under this Indenture (including, without limitation, waivers, amendments, consents, redemptions and offers to purchase). With respect to any Additional Notes or any Other Notes, the Corporation shall set forth in a Corporation Order, a copy of which shall be delivered to the Trustee, the aggregate principal amount of such Additional Notes or Other Notes to be authenticated and delivered pursuant to this Indenture, and the Holder(s), issue date and first Interest Payment Date of such Additional Notes or Other Notes.

2.3 Interest

Interest on the Notes will accrue at the rate of 8.125% per annum and will be payable semi-annually in arrears on June 3 and December 3 of each year, commencing on June 3, 2026. The Corporation will make each interest payment to the Holders of record as of the close of business on the fifth Business Day immediately preceding each Interest Payment Date. For purposes of disclosure under the Interest Act (Canada), the yearly rate of interest to which interest is calculated under a Note for any period in any calendar year (the “Calculation Period”) is equivalent to the rate payable under a Note in respect of the Calculation Period multiplied by a fraction the numerator of which is the actual number of days in such calendar year and the denominator of which is the actual number of days in the Calculation Period.

Interest on the Notes will accrue from the Issue Date or, if interest has already been paid, from the date it was most recently paid. Interest will be computed on the basis of a 365-day year or 366-day year, as applicable, and will be payable in equal semi-annual amounts; except that interest in respect of any period that is longer or shorter than a full semi-annual interest period will be computed on the basis of a 365-day year or 366-day year, as applicable, and the actual number of days elapsed in the relevant period.

If an Interest Payment Date falls on a day that is not a Business Day, the interest payment to be made on such Interest Payment Date will be made on the next succeeding Business Day with the same

35

force and effect as if made on such Interest Payment Date, and no additional interest will accrue solely as a result of such delayed payment. Interest on overdue principal and interest will accrue at the applicable interest rate on the Notes.

2.4 Currency of Payment

The principal of, premium (if any) and interest on the Notes will be payable in Canadian dollars.

2.5 Additional Amounts

All payments made by or on behalf of the Corporation under or with respect to the Notes or by or on behalf of any Guarantor under or with respect to any Subsidiary Guarantee will be made free and clear of, and without withholding or deduction for or on account of, any present or future Taxes, unless the Corporation or any Guarantor is required to withhold or deduct Taxes by law or by the interpretation or administration thereof. If the Corporation, any Guarantor or other payor is so required to withhold or deduct any amount for or on account of Taxes from any payment made under or with respect to the Notes or any Subsidiary Guarantee, as the case may be, the Corporation, such Guarantor or other payor, as applicable, will pay (together with such payment), as interest, such additional amounts (“Additional Amounts”) as may be necessary so that the net amount received by each Holder or beneficial owner of a Note after such withholding or deduction (including any such withholding or deduction from Additional Amounts) will not be less than the amount the Holder or beneficial owner would have received if such Taxes had not been withheld or deducted; provided that no Additional Amounts will be payable with respect to Taxes to the extent such Taxes:

(1) would not have been so imposed but for the Holder or beneficial owner not dealing at arm’s length (within the meaning of the Tax Act) at the time of making such payment with the Corporation, such Guarantor or other payor;

(2) would not have been so imposed but for the existence of any present or former connection between such Holder or beneficial owner and Canada or any political subdivision thereof or authority thereof having power to tax other than the mere acquisition, ownership or holding of Notes, the enforcement of rights thereunder or the receipt of payments thereunder;

(3) are imposed, withheld or deducted on any payment on a Note to the Holder of a Note as a consequence of the Holder or beneficial owner of the Note being a “specified shareholder” or a “specified non-resident shareholder” (each as defined in subsection 18(5) of the Tax Act) of the Corporation in the taxation year of the Corporation in which the payment is made;

(4) are imposed, withheld or deducted by reason of the failure of the Holder or beneficial owner to duly and timely comply with a timely request of the Corporation to provide information, documents, certification or other evidence concerning such Holder’s or beneficial owner’s nationality, residence, entitlement to treaty benefits, identity or connection with Canada or any political subdivision or authority thereof having the power to tax, if and to the extent that due and timely compliance with such request would have resulted in the reduction or elimination of any Taxes as to which Additional Amounts would have otherwise been payable to such Holder or beneficial owner of Notes but for this clause (4);

(5) are imposed, withheld or deducted on any payment on a Note or Subsidiary Guarantee to the Holder of a Note which is a fiduciary, partnership or person other than the sole beneficial owner of that payment, to the extent that such payment would be required to be included in income under the laws of the relevant taxing jurisdiction for tax purposes, of a beneficiary or settler with respect to the fiduciary, a member of that partnership or a beneficial owner who would not have been entitled to such Additional Amounts had that beneficiary, settler, partner or beneficial owner been the Holder or beneficial owner of the Note;

36

(6) would not have been imposed but for the presentation (where presentation is required) by such Holder or beneficial owner of the Note for payment more than 30 days after: (i) the date such payment on such Note became due and payable; or (ii) the date on which payment thereof is duly provided for, whichever is the later;

(7) are required to be deducted or withheld as a result of an assignment or transfer of the Notes by the Holder or beneficial owner to a person resident in Canada with whom the Holder or beneficial owner does not deal at arm’s length for purposes of the Tax Act;

(8) are Taxes imposed on or measured by the applicable Holder or beneficial owner’s net income, capital franchise taxes and branch profits or similar taxes;

(9) are estate, inheritance, gift, personal property, sales, use, excise, transfer or other similar Taxes imposed with respect to such payment;

(10) result from the failure of the Holder to comply with the US Foreign Account Tax Compliance Act and related applicable intergovernmental agreements or local implementing legislation; or

(11) any combination of the foregoing clauses of this provision (each an “Excluded Tax”).

The Corporation, such Guarantor or other payor, as the case may be, will also (a) make such withholding or deduction and (b) remit the full amount deducted or withheld to the relevant authority in accordance with applicable law. The Corporation, such Guarantor or other payor, as the case may be, will furnish to the Holders and beneficial owners of the Notes, within 30 days after the date the payment of any Taxes are due pursuant to applicable law, certified copies of tax receipts evidencing such payment by the Corporation, such Guarantor or other payor. The Corporation and each Guarantor will indemnify and hold harmless each Holder and beneficial owner (other than for Excluded Taxes) for the amount of (A) any Taxes not withheld or deducted by or on behalf of the Corporation or such Guarantor, as the case may be, and levied or imposed and paid by such Holder or beneficial owner as a result of payments made under or with respect to the Notes or the Subsidiary Guarantees, as the case may be (including, for greater certainty, any Taxes payable under section 803 of the regulations under the Tax Act), (B) any liability (including penalties, interest and expenses) arising therefrom or with respect thereto, and (C) any Taxes imposed with respect to any reimbursement under clauses (A) or (B) above.

At least 30 days prior to each date on which any payment under or with respect to the Notes is due and payable, if the Corporation or any Guarantor is aware that it will be obligated to pay Additional Amounts with respect to such payment, the Corporation will deliver to the Trustee an Officers’ Certificate stating the fact that such Additional Amounts will be payable, the amounts so payable and will set forth such other information necessary to enable the Trustee to pay such Additional Amounts to Holders or beneficial owners, as the case may be, on the payment date. Whenever in this Indenture or this description there is mentioned, in any context, the payment of principal (and premium, if any), redemption prices or purchase prices in connection with a redemption or purchase of Notes, interest or any other amount payable under or with respect to any Note, such mention shall be deemed to include mention of the payment of Additional Amounts provided for in this section to the extent that, in such context, Additional Amounts are, were or would be payable in respect thereof.

The Corporation will pay when due any present or future stamp, transfer, court or documentary taxes or any other excise or property taxes, charges or similar levies (including penalties and interest related thereto) which arise in any governing jurisdiction from the initial execution, delivery, issuance or registration of the Notes or any other document or instrument relating thereto or from any payment under or in respect of, or enforcement of, the Notes or any Subsidiary Guarantee (“Documentary Taxes”).

The obligations under this Section 2.5, including, for greater certainty, the Corporation’s and each Guarantor’s obligation to make payments of Additional Amounts, any indemnification payment and Documentary Taxes under the terms and conditions under this Section 2.5 will survive any termination, defeasance or discharge of this Indenture and any transfer by a Holder or beneficial owner of Notes.

(ii) in the case of uncertificated Notes, such Notes shall, for all purposes of this Indenture, be deemed to have been duly authenticated by or on behalf of the Trustee if the Trustee has, in respect of such Notes, completed all Internal Procedures such that the particulars of such Notes as required by Section 3.2 are entered in the applicable register referred to in Section 3.2; and such authentication will be conclusive evidence, and the only evidence, that such uncertificated Notes have been duly authenticated and issued and that the Holder thereof is entitled to the benefits hereof.

(c) If the date for payment of any amount of interest in respect of a Note is not a Business Day at the place of payment, then payment thereof will be made on the next Business Day and the Holder of such Note will not be entitled to any further interest or other amount solely as a result of such delayed payment.

(d) The Holder of any Note at the close of business on any Record Date with respect to any Interest Payment Date shall be entitled to receive the interest, if any, payable on such Interest Payment Date notwithstanding any transfer or exchange of such Note subsequent to such Record Date and prior to such Interest Payment Date, except if and to the extent the Corporation shall default in the payment of the interest due on such Interest Payment Date, in which case such defaulted interest shall be paid to the Persons in whose names such Note is registered at the close of business on a subsequent Record Date (which shall be not less than two Business Days prior to the date of payment of such defaulted interest) established by notice given in accordance with Section 13.2 by or on behalf of the Corporation to the Holders of all affected Notes not less than 15 days preceding such subsequent Record Date.

41

(e) Wherever in this Indenture or any Note there is mention, in any context, of the payment of interest, such mention is deemed to include the payment of interest on amounts in default to the extent that, in such context, such interest is, was or would be payable pursuant to this Indenture or the Note, and express mention of interest on amounts in default in any of the provisions of this Indenture will not be construed as excluding such interest in those provisions of this Indenture where such express mention is not made.

(f) Interest on Notes shall be payable in equal semi-annual amounts; provided that for any period other than a full semi-annual Interest Period, interest shall be calculated on the basis of a year of 365 or 366-day year, as applicable, and the actual number of days elapsed in that period.

(g) For purposes of disclosure under the Interest Act (Canada), the yearly rate of interest to which interest is calculated under a Note for any period in any calendar year (the “Calculation Period”) is equivalent to the rate payable under a Note in respect of the Calculation Period multiplied by a fraction the numerator of which is the actual number of days in such calendar year and the denominator of which is the actual number of days in the Calculation Period.

2.16 Payment of Interest

(a) The Corporation shall pay the interest due upon the principal amount of each Definitive Note (except interest payable on Maturity or redemption of a Definitive Note which, at the option of the Corporation, may be paid only upon presentation of such Definitive Note for payment) by forwarding or causing to be forwarded by prepaid ordinary mail (or in the event of mail service interruption, by such other means as the Trustee and the Corporation determine to be appropriate) a cheque for such interest payable to the Holder of such Definitive Note on the Record Date for each applicable Interest Payment Date at the address appearing on the applicable register unless otherwise directed in writing by the Holder or, in the case of registered joint Holders, payable to all such joint Holders and addressed to one of them at the last address appearing in the applicable register and negotiable at par at each of the places at which interest upon such Definitive Note is payable. The forwarding of such cheque shall satisfy and discharge the liability for the interest on such Definitive Note to the extent of the sum represented thereby unless such cheque is not paid on presentation at any of the places at which such interest is payable. In the event of the non-receipt of such cheque by the applicable Holder or the loss, theft or destruction thereof, the Corporation, upon being furnished with evidence of such non-receipt, loss, theft or destruction and indemnity reasonably satisfactory to it shall issue or cause to be issued to such Holder a replacement cheque for the amount of such cheque. Notwithstanding the foregoing, the Corporation, at its option, may cause the amount payable in respect of interest to be paid to a Holder by wire or other electronic transfer to an account maintained by such Holder or in any other manner acceptable to the Trustee. If payment of interest is made by cheque, the Corporation shall transfer funds to the Trustee at least four Business Days prior to the applicable Interest Payment Date, and if payment is made in any other manner, such payment shall be made in a manner whereby the recipient receives credit for such payment on or prior to the applicable Interest Payment Date.

(b) The Corporation shall pay the interest due upon the principal amount of each Global Note by wire or other electronic funds transfer by the Corporation either (i) to the Trustee (and then by the Trustee to the Depository or its nominee) or (ii) directly to the Depository or its nominee, unless the Corporation, the Trustee and/or the Depository, as applicable, otherwise agree. Such funds as are required for the payments of interest on Global Notes shall be transferred by the Corporation to the Trustee or the Depository (or its nominee), as applicable, by wire or other electronic transfer on or before 11:00 a.m. (Calgary time) on the Business Day before the Interest Payment Date, unless the Corporation, the Trustee

42

and/or Depository, as applicable, otherwise agree. If the funds are transferred to the Trustee, the Trustee shall pay such funds (to the extent actually received by the Trustee) to the Depository or its nominee on or prior to the applicable Interest Payment Date. The transfer of funds by the Corporation to the Trustee or to the Depository (or its nominee), as applicable, with respect to the payment of interest will satisfy and discharge the liability of the Corporation in respect of the interest then due on such Global Note to the extent of the amount transferred.

(c) Notwithstanding Sections 2.16(a) and (b), all payments made under this Section 2.16 in excess of $25,000,000 (or such other amount as determined from time to time by the Canadian Payments Association or any successor thereto) shall be made by the use of the LVTS.

2.17 Payments of Amounts Due on Maturity

(a) In the case of any Notes represented, in whole or in part, by Definitive Notes, the Corporation shall (prior to the Maturity for such Definitive Notes) establish and maintain with the Trustee a Maturity Account for such Definitive Notes. On or before 11:00 a.m. (Calgary time) on the Business Day before the Maturity for such Definitive Notes, the Corporation shall deposit in the applicable Maturity Account by wire or other electronic transfer or by certified cheque an amount sufficient to pay the principal amount of, premium (if any) on and accrued and unpaid interest (if any) payable in respect of such Definitive Notes. The Trustee will pay to each Holder of such Definitive Notes entitled to receive payment, the principal amount of, and premium (if any) on and accrued and unpaid interest (if any) (less any Taxes required by law to be deducted or withheld therefrom) on such Definitive Notes, upon surrender of such Definitive Notes to the Trustee. The deposit or making available of such amounts into the applicable Maturity Account will satisfy and discharge the liability of the Corporation for such Definitive Notes to which the deposit or making available of funds relates to the extent of the amount deposited or made available (plus the amount of any Taxes deducted or withheld as aforesaid) and such Definitive Notes will thereafter not be considered as outstanding under this Indenture to such extent and such Holders will have no other right except to receive out of the amount so deposited or made available the amount to which they are entitled. Failure to make a deposit or make funds available as required to be made pursuant to this Section 2.17(a) will constitute Default in payment on the Notes in respect of which the deposit or making available of funds was required to have been made.

(b) In the case of any Notes represented, in whole or in part, by Global Notes, on or before 11:00 a.m. (Calgary time) on the Business Day before the Maturity for such Global Notes, the Corporation shall deliver either (i) to the Trustee to transfer to the Depository or its nominee or (ii) directly to the Depository or its nominee, by wire or other electronic funds transfer an amount sufficient to pay the principal amount of, premium (if any) on and accrued and unpaid interest (if any) payable in respect of such Global Notes (less any Taxes required by law to be deducted or withheld therefrom). If such payment is made to the Trustee, the Trustee shall pay such amount to the Depository or its nominee. The delivery of such wire or other electronic funds to the Trustee or Depository (or its nominee), as applicable, will satisfy and discharge the liability of the Corporation for such Global Notes to which the deposit or making available of funds relates to the extent of the amount deposited or made available (plus the amount of any Taxes deducted or withheld as aforesaid) and such Global Notes will thereafter not be considered as outstanding under this Indenture unless such wire or other electronic funds transfer is not received. Failure to deliver or make funds available as required to be made pursuant to this Section 2.17(a) will constitute Default in payment on the Notes in respect of which the delivery or making available of funds was required to have been made.

43

(c) Notwithstanding Sections 2.17(a) and (a), all payments made under this Section 2.17 in excess of $25,000,000 (or such other amount as determined from time to time by the Canadian Payments Association or any successor thereto) shall be made by the use of the LVTS.

2.18 Legends on Notes

(a) Any Notes offered and sold in the United States will be offered and sold only to (i) Persons who are QIBs within the meaning of, and in reliance on, Rule 144A under the 1933 Act or (ii) Accredited Investors as defined in and in reliance on Regulation D under the 1933 Act, as well as all Notes issued in exchange for or in substitution of the foregoing securities, and shall bear (or, in the case of uncertificated Notes, shall be deemed to bear), unless otherwise directed by the Corporation, the following legend until the legend is no longer required under U.S. securities laws and regulations:

“UNLESS PERMITTED UNDER APPLICABLE SECURITIES LEGISLATION IN CANADA, THE HOLDER OF THIS NOTE MUST NOT TRADE THIS NOTE IN CANADA BEFORE THE DATE THAT IS FOUR MONTHS AND A DAY AFTER THE DATE OF ISSUANCE OF THE NOTES.

THE NOTES EVIDENCED HEREBY HAVE NOT BEEN REGISTERED UNDER THE SECURITIES ACT OF 1933, AS AMENDED (THE “SECURITIES ACT”), OR OTHER SECURITIES LAWS. NEITHER THIS NOTE NOR ANY INTEREST OR PARTICIPATION HEREIN MAY BE REOFFERED, SOLD, ASSIGNED, TRANSFERRED, PLEDGED, ENCUMBERED OR OTHERWISE DISPOSED OF IN THE ABSENCE OF SUCH REGISTRATION OR UNLESS THE TRANSACTION IS EXEMPT FROM, OR NOT SUBJECT TO, THE REGISTRATION REQUIREMENTS OF THE SECURITIES ACT. [EACH PURCHASER OF THE SECURITY EVIDENCED HEREBY IS NOTIFIED THAT THE SELLER MAY BE RELYING ON THE EXEMPTION FROM SECTION 5 OF THE SECURITIES ACT PROVIDED BY RULE 144A THEREUNDER.]1 THE HOLDER HEREOF AGREES THAT IT WILL GIVE TO EACH PERSON TO WHOM THIS NOTE IS TRANSFERRED A NOTICE SUBSTANTIALLY TO THE EFFECT OF THIS LEGEND AS USED HEREIN.”

(b) The Notes have not been and will not be qualified for distribution to the public under Canadian securities laws and regulations, and all Notes will bear (or, in the case of uncertificated Notes, shall be deemed to bear), unless otherwise directed by the Corporation, a legend in substantially the following form until the legend is no longer required under applicable securities laws and regulations:

“UNLESS PERMITTED UNDER APPLICABLE SECURITIES LEGISLATION IN CANADA, THE HOLDER OF THIS NOTE MUST NOT TRADE THIS NOTE IN CANADA BEFORE THE DATE THAT IS FOUR MONTHS AND A DAY AFTER THE DATE OF ISSUANCE OF THE NOTES.”

(c) Each certificate representing a Global Note shall bear a legend in substantially the following form, subject to such modification as required by the Depository (the “Global Note Legend”):

“UNLESS THIS CERTIFICATE IS PRESENTED BY AN AUTHORIZED REPRESENTATIVE OF CDS CLEARING AND DEPOSITORY SERVICES INC. (“CDS”) TO OBSIDIAN ENERGY LTD. (THE “CORPORATION”) OR ITS AGENT FOR REGISTRATION OF TRANSFER, EXCHANGE OR PAYMENT, AND ANY CERTIFICATE ISSUED IN RESPECT THEREOF IS REGISTERED IN THE NAME OF CDS & CO., OR

1 Bracketed language to be added to 144A Global Note only.

44

IN SUCH OTHER NAME AS IS REQUESTED BY AN AUTHORIZED REPRESENTATIVE OF CDS (AND ANY PAYMENT IS MADE TO CDS & CO. OR TO SUCH OTHER ENTITY AS IS REQUESTED BY AN AUTHORIZED REPRESENTATIVE OF CDS), ANY TRANSFER, PLEDGE OR OTHER USE HEREOF FOR VALUE OR OTHERWISE BY OR TO ANY PERSON IS WRONGFUL SINCE THE REGISTERED HOLDER HEREOF, CDS & CO., HAS A PROPERTY INTEREST IN THE SECURITIES REPRESENTED BY THIS NOTE HEREIN AND IT IS A VIOLATION OF ITS RIGHTS FOR ANOTHER PERSON TO HOLD, TRANSFER OR DEAL WITH THIS NOTE.”

2.19 Right to Receive Indenture

Each Holder and each Beneficial Holder (that provides a sworn affidavit confirming such beneficial interest) is entitled to receive from the Corporation a copy of this Indenture and any Supplemental Indentures relating to the Notes upon written request and payment of a reasonable fee.

Article 3
REGISTRATION, TRANSFER, EXCHANGE AND OWNERSHIP

3.1 Register of Definitive Notes

(a) With respect to Definitive Notes, the Corporation shall cause to be kept by the Trustee at the principal office of the Trustee in Calgary, Alberta or by such other Registrar as the Corporation, with the approval of the Trustee, may appoint at such other place or places, if any, as the Corporation may designate with the approval of the Trustee, a register in which shall be entered the names and addresses of the Holders and particulars of the Definitive Notes held by them respectively and of all transfers and exchanges of such Definitive Notes.

(b) No transfer of a Definitive Note shall be valid unless (i) made by the Holder or such ▇▇▇▇▇▇’s executors, administrators or other legal representatives or an attorney duly appointed by an instrument in writing in form and executed in a manner satisfactory to the Trustee or other Registrar upon surrender of such Definitive Note together with a duly executed form of transfer acceptable to the Trustee or other Registrar and upon compliance with such other reasonable requirements as the Trustee or other Registrar may prescribe and (ii) such transfer has been duly noted on such Definitive Note and on the registers by the Trustee or other Registrar.

(c) A Holder of a Definitive Note may only transfer such Definitive Note in compliance with the provisions of any legend or legends thereon restricting such transfer and in accordance with applicable law.

3.2 Global Notes

(a) With respect to Notes represented by Global Notes, the Corporation shall cause to be kept by the Trustee at the principal office of the Trustee in Calgary, Alberta or by such other Registrar as the Corporation, with the approval of the Trustee, may appoint at such other place or places, if any, as the Corporation may designate with the approval of the Trustee, a register in which shall be entered the name and address of the Holder of each Global Note (being the Depository, or its nominee, for each Global Note) and particulars of the Global Note held by it, and of all transfers and exchanges thereof.

(b) Notwithstanding any other provision of this Indenture, a Global Note may not be transferred by the Holder thereof and no Definitive Notes shall be issued to Beneficial Holders of Global Notes, except in the following circumstances:

45

(i) Definitive Notes may be issued to Beneficial Holders of Global Notes at any time after:

(A) the Corporation has determined, or has been notified by the Depository, and written notice thereof has been provided to the Trustee, that the Depository (1) is unwilling or unable to continue as Depository for the Global Notes or (2) ceases to be eligible to be a Depository, and in each such case the Corporation is unable to locate a qualified successor to its reasonable satisfaction;

(B) the Corporation has determined, in its sole discretion, or is required by law, and written notice thereof has been provided to the Trustee, to terminate the book-based or book-entry only system, as applicable, in respect of such Global Notes and has communicated such determination or requirement to the Trustee in writing, or the book-based or book-entry only system, as applicable, ceases to exist; or

(C) the Trustee has determined that an Event of Default has occurred and is continuing with respect to Notes issued as Global Notes; provided that Beneficial Holders representing, in the aggregate, not less than 50% of the aggregate outstanding principal amount of the Notes represented by Global Notes advise the Depository in writing, through the Participants, that the continuation of the book-based or book-entry only system, as applicable, for the Notes is no longer in their best interests; and

(ii) Global Notes may be transferred (A) if such transfer is required by applicable law, as determined by the Corporation and Counsel or (B) by a Depository to a nominee of such Depository, or by a nominee of a Depository to such Depository, or to another nominee of such Depository, or by a Depository or its nominee to a successor Depository or its nominee.

(c) Upon the occurrence of one of the conditions specified in Section 3.2(b)(i) or upon a requirement arising to transfer a Global Note to a Person other than a Depository or a nominee thereof in accordance with Section 3.2(b)(ii), the Trustee shall notify all applicable Participants, through the Depository, of the availability of Definitive Notes. Upon surrender by the Depository of the Global Notes and receipt of new registration instructions from the Depository, the Corporation shall execute, and, upon receipt by the Trustee of a Corporation Order, the Trustee shall authenticate and deliver, Definitive Notes (in a form to be agreed to by the Corporation and the Trustee) to the Beneficial Holders thereof in accordance with the new registration instructions and thereafter, the registration and transfer of such Notes will be governed by Section 3.1 and the remaining provisions of this Article 3 applicable to Definitive Notes.

(d) It is expressly acknowledged that transfers of beneficial ownership in any Note represented by a Global Note will be effected only (i) with respect to the interests of participants in the Depository (“Participants”), through records maintained by the Depository or its nominee for the Global Note and (ii) with respect to interests of Persons other than Participants, through records maintained by Participants. Beneficial Holders who are not Participants but who desire to purchase, sell or otherwise transfer ownership interests in Notes represented by a Global Note may do so only through a Participant.

3.3 Transferee Entitled to Registration

The transferee of a Note shall be entitled, after the appropriate form of transfer is deposited with the Trustee or other Registrar and upon compliance with all other conditions for such transfer required by this Indenture or by law, to be entered on the register as the owner of such Note free from all equities or

46

rights of set-off or counterclaim between the Corporation and the transferor or any previous Holder of such Note, save in respect of equities of which the Corporation is required to take notice by law (including any statute or order of a court of competent jurisdiction).

3.4 No Notice of Trusts

None of the Corporation, the Trustee and any Registrar or Paying Agent will be bound to take notice of or see to the performance or observance of any duty owed to a third Person, whether under a trust, express, implied, resulting or constructive, in respect of any Note by the Holder or any Person whom the Corporation or the Trustee treats, as permitted or required by law, as the owner or the Holder of such Note, and may transfer the same on the direction of the Person so treated as the owner or Holder of the Note, whether named as trustee or otherwise, as though that Person were the Beneficial Holder thereof.

3.5 Registers Open for Inspection

The registers referred to in Sections 3.1 and 3.2 shall, subject to applicable law, at all reasonable times and upon prior written notice be open for inspection by the Corporation, the Trustee, any Holder and any Beneficial Holder (that provides a sworn affidavit confirming such beneficial interest). Every Registrar, including the Trustee, shall from time to time when requested to do so by the Corporation or by the Trustee, in writing, furnish the Corporation or the Trustee, as the case may be, with a list of names and addresses of Holders entered on the registers kept by them and showing the principal amount and serial numbers (or other applicable information) of the Notes held by each such Holder.

3.6 Transfers and Exchanges of Notes

(a) Transfer and Exchange of Global Notes. A Global Note may be transferred, and a beneficial interest in a Global Note may be exchanged for a Definitive Note, in each case, only pursuant to Section 3.2(b); provided, however, that a beneficial interest in a Global Note may be transferred and exchanged as provided in Section 3.6(b).

(b) Transfer and Exchange of Beneficial Interests in the Global Notes. The transfer and exchange of beneficial interests in Global Notes shall be effected through the Depository, in accordance with the provisions of this Indenture, the Applicable Procedures and applicable law. Transfers and exchanges of beneficial interests in Global Notes shall also require compliance with either Section 3.6(b)(i) or Section 3.6(b)(ii), as applicable:

(i) Transfer of Beneficial Interests in the Same Global Note. Beneficial interests in a Global Note may be transferred to Persons who take delivery thereof in the form of a beneficial interest in the same Global Note if such beneficial interest is being transferred in accordance with any transfer restrictions or legends set forth in or applicable to such Global Note.

(ii) All Other Transfers and Exchanges of Beneficial Interests in Global Notes. In connection with all transfers and exchanges of beneficial interests that are not subject to Section 3.6(b)(i), the transferor of such beneficial interest must deliver (A) instructions to the Registrar from a Participant or the Beneficial Holder, in each case, in accordance with the Applicable Procedures, that directs the Depository to credit or cause to be credited a beneficial interest in another Global Note (that is outstanding or that the Corporation permits to become outstanding) in an amount equal to the beneficial interest to be transferred or exchanged and (B) such other documents, instruments and legal opinions as the Trustee, the Registrar and the Corporation reasonably request. Upon satisfaction of all of the requirements for transfer or exchange of beneficial interests in Global Notes contained in this Indenture and compliance with any transfer restrictions or legends set forth in or

47

applicable to the relevant Global Notes, the Trustee shall adjust the principal amount of the relevant Global Notes pursuant to Section 3.6(c).

(c) Cancellation and/or Adjustment of Global Notes. At such time as all beneficial interests in a particular Global Note have been exchanged for Definitive Notes or exchanged or transferred to a Person (or Persons) that take delivery thereof in the form of a beneficial interest in one or more different Global Notes, or a particular Global Note has been redeemed, repurchased or canceled in whole and not in part, each such Global Note shall be returned to or retained and canceled by the Trustee in accordance with Section 3.10. At any time prior to such cancellation, if any beneficial interest in a Global Note is exchanged for or transferred to a Person who will take delivery thereof in the form of a beneficial interest in another Global Note or for Definitive Notes, the principal amount of Notes represented by such Global Note shall be reduced accordingly and an endorsement shall be made on such Global Note (or in the case of uncertificated Global Notes, in accordance with the Trustee’s Internal Procedures) by the Trustee or by the Depository at the direction of the Trustee to reflect such reduction; and if the beneficial interest is being exchanged for or transferred to a Person who will take delivery thereof in the form of a beneficial interest in another Global Note, such other Global Note shall be increased accordingly and an endorsement shall be made on such Global Note (or in the case of uncertificated Global Notes, in accordance with the Trustee’s Internal Procedures) by the Trustee or by the Depository at the direction of the Trustee to reflect such increase.

(d) General Provisions Relating to Transfers and Exchanges.

(i) To permit registrations of transfers and exchanges, the Corporation shall execute (in the case of certificated Notes) and, upon receipt by the Trustee of a Corporation Order, the Trustee shall authenticate, Global Notes and Definitive Notes in accordance with or at the Registrar’s request, and in accordance with the provisions of Section 2.8.

(ii) All Global Notes and Definitive Notes issued upon any registration of transfer or exchange shall be valid obligations of the Corporation, evidencing the same debt and entitled to the same benefits under this Indenture as the Global Notes or Definitive Notes surrendered upon such registration of transfer or exchange.

(iii) At the option of the Holder, Notes may be exchanged for other Notes of any authorized denomination or denominations of a like aggregate principal amount upon surrender of such Notes to be exchanged at the office or agency of the Registrar. Whenever any Global Notes or Definitive Notes are so surrendered for exchange, the Corporation shall execute (in the case of certificated Notes) and, upon receipt by the Trustee of a Corporation Order, the Trustee shall authenticate and deliver, the replacement Global Notes and Definitive Notes which the Holder making the exchange is entitled to in accordance with the provisions of Section 2.8.

(iv) The Trustee shall have no obligation or duty to monitor, determine or inquire as to compliance, and shall not be responsible or liable for compliance, with any restrictions on transfer, exchange, redemption, purchase or repurchase, as applicable, imposed under this Indenture or under applicable law or regulation with respect to any transfer, exchange, redemption, purchase or repurchase, as applicable of any interest in any Note (including, without limitation, any transfers between or among Participants or Beneficial Holder) other than to require delivery of such certificates and other documentation or evidence as are expressly required by, and to do so if and when expressly required by, the terms of this Indenture, and to examine the same to determine substantial compliance as to form with the express requirements hereof, it being understood that without limiting the

48

generality of the foregoing, the Trustee shall not have any obligation or duty to monitor, determine or inquire as to compliance, and shall not be responsible or liable for compliance, with restrictions on transfer, exchange, redemption, purchase or repurchase, as applicable, of minimum denominations imposed under this Indenture or under applicable law or regulation with respect to any transfer, exchange, redemption, purchase or repurchase, as applicable, of any interest in any Note.

(v) Neither the Trustee nor the Corporation shall have any responsibility for any actions taken or not taken by the Depository.

(vi) The Trustee shall have no responsibility or obligation to any Beneficial Holder, any Participant or any other Person with respect to the accuracy of the records of the Depository or its nominee or of any Participant thereof, with respect to any ownership interest in the Notes or with respect to the delivery to any Participant, Beneficial Holder or other Person (other than the Depository) of any notice (including any Redemption Notice) or the payment of any amount, under or with respect to such Notes. All notices and communications to be given to the Holders and all payments to be made to Holders under the Notes shall be given or made only to the registered Holders. The Trustee may rely and shall be fully protected in relying upon information furnished by the Depository with respect to its Participants and any Beneficial Holder.

3.7 Closing of Registers

(a) Neither the Corporation nor the Trustee nor any Registrar shall be required to:

(i) register the transfer of or exchange Notes on any Interest Payment Date or between a Record Date and the related Interest Payment Date;

(ii) register the transfer of or exchange any Note selected for redemption in whole or in part, except the unredeemed portion of any Note being redeemed in part; or

(iii) register the transfer of or exchange any Note tendered and not withdrawn in connection with a Change of Control Offer or an Asset Sale Offer, except for the unpurchased portion of any Note tendered in part only.

(b) Subject to any restriction provided in this Indenture, the Corporation with the approval of the Trustee may at any time close any register for the Notes (other than those kept at the principal office of the Trustee in Calgary, Alberta) and transfer the registration of any Notes registered thereon to another register (which may be an existing register) and thereafter such Notes shall be deemed to be registered on such other register. Notice of such transfer shall be given to the Holders of such Notes.

3.8 Charges for Registration, Transfer and Exchange

For each Note exchanged, registered or transferred, the Trustee or other Registrar, except as otherwise herein provided, may make a reasonable charge for its services and in addition may charge a reasonable sum for each new Note issued (such amounts to be agreed upon from time to time by the Trustee and the Corporation), and payment of such charges and reimbursement of the Trustee or other Registrar for any stamp taxes or governmental or other charges required to be paid shall be made by the party requesting such exchange, registration or transfer as a condition precedent thereto. Notwithstanding the foregoing provisions, no charge shall be made to a Holder hereunder:

49

(a) for any exchange, registration or transfer of any Note applied for within a period of two months from the date of the first delivery thereof;

(b) for any exchange of a Global Note as contemplated in Section 3.2; or

(c) for any exchange of any Note resulting from any partial redemption or repurchase.

3.9 Ownership of Notes

(a) The Holder for the time being of any Note shall be deemed to be the owner thereof for all purposes of this Indenture and shall be entitled to the principal, premium (if any) and interest on such Note, free from all equities or rights of set-off or counterclaim between the Corporation and the original or any intermediate Holder thereof (except in respect of equities of which the Corporation is required to take notice by law) and all Persons may act accordingly and the receipt of any such Holder for any such principal, premium (if any) and interest shall be a valid discharge to the Trustee, any Registrar, any Paying Agent and to the Corporation for the same and none shall be bound to inquire into the title of any such Holder.

(b) Where Notes are registered in more than one name, the principal, premium (if any) and interest from time to time payable in respect thereof may be paid to the order of all such Holders, and the receipt of any one of such Holders therefor shall be a valid discharge to the Trustee, any Registrar, any Paying Agent and to the Corporation.

3.10 Cancellation

All matured, redeemed or repurchased (a) certificated Notes shall forthwith after payment of all obligations thereunder be delivered to the Trustee and cancelled by the Trustee and (b) uncertificated Notes shall forthwith after payment of all obligations thereunder be cancelled by the Trustee in accordance with the Trustee’s Internal Procedures.

Article 4

4.1 Optional Redemption

(a) At any time prior to December 3, 2027, the Corporation may on any one or more occasions redeem all or a part of the Notes, upon not less than 10 days’ nor more than 60 days’ notice, at a redemption price which is equal to the Canada Yield Price, plus accrued and unpaid interest, if any, to the date of redemption.

(b) At any time prior to December 3, 2027, the Corporation may on any one or more occasions redeem up to 40% of the Notes (including Additional Notes) issued under this Indenture, upon not less than 10 days’ nor more than 60 days’ notice, at a redemption price which is equal to 108.125% of the aggregate principal amount of the Notes being redeemed, plus accrued and unpaid interest, if any, to, but not including, the date of redemption with all or a portion of the Net Cash Proceeds of one or more Equity Offerings; provided that Notes (excluding Notes held by the Corporation and its Subsidiaries) representing at least 60% of the aggregate principal amount of the Notes issued under this Indenture on the Issue Date remain outstanding immediately after the occurrence of such redemption; and provided, further, that such redemption occurs within 180 days of the date of the closing of any such Equity Offering.

50

or interpretation thereof (including a holding by a court of competent jurisdiction or an official administrative position or interpretation by a taxing authority), which is publicly announced and becomes effective or made available on or after the Issue Date, the Corporation becomes obligated to pay, on the next date on which any amount would be payable with respect to the Notes, Additional Amounts, and such Additional Amounts cannot in the reasonable business judgement of the Corporation be avoided by the use of reasonable measures available to the Corporation, then the Corporation may, at its option, redeem the Notes in whole but not in part, upon not less than 10 days’ nor more than 60 days’ prior notice, at a redemption price equal to 100% of the principal amount thereof, plus accrued and unpaid interest to the redemption date. Notice of the Corporation’s intent to redeem the Notes will not be effective until such time as it delivers to the Trustee an opinion of counsel of the relevant taxing jurisdiction (provided such opinion is reasonably acceptable to the Trustee) setting forth in reasonable detail the circumstances giving rise to the obligation to pay Additional Amounts because of the applicable change (or proposed change) in the laws or regulations of Canada or any Canadian taxing authority, or a change in any official position regarding the application or interpretation thereof (including a holding by a court of competent jurisdiction or an official administrative position or interpretation by a taxing authority), as described in this paragraph.

(e) On or after December 3, 2027, the Corporation may, on any one or more occasions, redeem all or a part of the Notes upon not less than 10 days’ nor more than 60 days’ notice, at the redemption prices (expressed as percentages of principal amount) set forth below plus accrued and unpaid interest, if any, on the Notes redeemed, to, but not including, the applicable redemption date, if redeemed during the twelve-month period beginning on December 3rd of the years indicated below:

(b) The Corporation or any of its Subsidiaries may at any time and from time to time purchase Notes in the open market or otherwise.

4.4 Partial Redemption

(a) If less than all of the Notes are to be redeemed at any time, the Trustee will select Notes for redemption as follows:

51

(i) if the Notes are listed on any securities exchange, in compliance with the requirements of the principal securities exchange on which the Notes are listed; or

(ii) if the Notes are not listed on any securities exchange, on a pro rata basis (or, in the case of Notes issued in global form, based on a method that most nearly approximates a pro rata selection as the Trustee deems fair and appropriate) unless otherwise required by applicable law or depositary requirements.

Notes or portions of Notes the Trustee selects for redemption shall be in minimum amounts of $2,000 or a multiple of $1,000 in excess thereof. Notices of redemption will be delivered or mailed by first class mail at least 10 days but not more than 60 days before the redemption date to each Holder of Notes to be redeemed at its registered address, except that optional redemption notices may be delivered or mailed more than 60 days prior to a redemption date if the notice is issued in connection with a defeasance of the Notes or a satisfaction and discharge of this Indenture. Notices of redemption may, at the Corporation’s discretion, be subject to one or more conditions precedent.

(b) If any Note is to be redeemed in part only, the notice of redemption that relates to that Note will state the portion of the principal amount of that Note that is to be redeemed. A new Note in principal amount equal to the unredeemed portion of the original Note will be issued in the name of the Holder of Notes upon cancellation of the original Note. Notes called for redemption become due on the date fixed for redemption. On and after the redemption date, interest ceases to accrue on Notes or portions of them called for redemption.

4.5 Notice of Redemption

Notice of redemption (a “Redemption Notice”) of any Notes shall be given to the Holders of the Notes to be redeemed not more than 60 days nor less than 10 days prior to the date fixed for redemption (the “Redemption Date”); provided that Redemption Notices in respect of optional redemptions of Notes may be mailed or delivered more than 60 days prior to a Redemption Date if the Redemption Notice is issued in connection with a defeasance of the relevant Notes or a satisfaction and discharge of this Indenture. Every such Redemption Notice shall specify the aggregate principal amount of Notes called for redemption, the Redemption Date, the redemption price and the places of payment and shall state that interest upon the principal amount of Notes called for redemption shall cease to be payable from and after the Redemption Date. Redemption Notices in respect of an optional redemption under Section 4.1 may, at the Corporation’s discretion, be subject to one or more conditions precedent and may be revoked if any such condition is not satisfied. In addition, unless all the outstanding Notes are to be redeemed, the Redemption Notice shall identify the particular Notes or portions thereof being redeemed.

4.6 Notes Due on Redemption Dates

Upon a Redemption Notice having been given as provided in Section 4.5, all the Notes so called for redemption or the principal amount to be redeemed of the Notes called for redemption, as the case may be, shall thereupon be and become due and payable at the applicable redemption price, together with accrued and unpaid interest to but excluding the Redemption Date, on the Redemption Date specified in such notice, in the same manner and with the same effect as if it were the final Stated Maturity specified in such Notes, anything therein or herein to the contrary notwithstanding (but subject to satisfaction or waiver of any conditions precedent applicable to such Redemption Notice in accordance with Section 4.5). From and after such Redemption Date, if the monies necessary to redeem such Notes shall have been deposited as provided in Section 4.7 and proof satisfactory to the Trustee as to the publication and/or mailing or delivery of such Redemption Notices shall have been provided to it, interest upon the Notes shall cease to accrue. If any question shall arise as to whether any notice has been given as above provided and such deposit made, such question shall be decided by the Trustee (acting in reliance on an Opinion of Counsel) whose decision shall be final and binding upon all parties in interest.

52

4.7 Deposit of Redemption Monies

Upon Notes being called for redemption, the Corporation shall deposit with the Trustee or any Paying Agent, on or before 11:00 a.m. (Calgary time) on the Business Day immediately prior to the Redemption Date specified in the Redemption Notice, such sums of money as may be sufficient to pay the redemption price of the Notes so called for redemption plus accrued and unpaid interest thereon to but excluding the Redemption Date and including any Additional Amounts, less any Taxes required by law to be deducted or withheld therefrom. The Corporation shall also deposit with the Trustee a sum of money sufficient to pay any charges or expenses which may be incurred by the Trustee in connection with such redemption. The Corporation shall also deposit with the Trustee a sum of money sufficient to pay any charges or expenses which may be incurred by the Trustee in connection with such redemption. Every such deposit shall be irrevocable. From the sums so deposited, the Trustee or Paying Agent shall pay or cause to be paid to the Holders of such Notes so called for redemption, upon surrender of such Notes, the principal, premium (if any) and interest to which they are respectively entitled on redemption. Payment of funds to the Trustee or Paying Agent upon redemption of Notes shall be made by wire or other electronic funds transfer or certified cheque or pursuant to such other arrangements for the provision of funds as may be agreed between the Corporation and the Trustee or Paying Agent in order to effect such payment hereunder. Notwithstanding the foregoing, (a) all payments in excess of $25,000,000 (or such other amount as determined from time to time by the Canadian Payments Association) shall be made by the use of the LVTS; and (b) in the event that payment must be made to the Depository, the Corporation shall remit payment to the Trustee by LVTS. The Trustee shall have no obligation to disburse funds pursuant to this Section 4.7 unless it has received written confirmation satisfactory to it that the funds have been deposited with it in sufficient amount to pay in full all amounts due and payable on the applicable Redemption Date. The Trustee shall, if it accepts any funds received by it in the form of uncertified cheques, be entitled to delay the time for release of such funds until such uncertified cheques shall be determined to have cleared the financial institution upon which the same are drawn.

4.8 Failure to Surrender Notes Called for Redemption

In case the Holder of any Note so called for redemption shall fail on or before the Redemption Date to surrender such Holder’s Note, or shall not within such time specified on the Redemption Notice accept payment of the redemption funds payable, such redemption monies may be set aside in trust, without interest, either in the deposit department of the Trustee or in a chartered bank, and such setting aside shall for all purposes be deemed a payment to the Holder of the sum so set aside and, to that extent, such Note shall thereafter not be considered as outstanding hereunder and the Holder thereof shall have no other right except to receive payment of such funds, less any taxes required by law to be deducted or withheld, out of the monies so paid and deposited. In the event that any funds required to be deposited hereunder with the Trustee or any Paying Agent on account of principal, premium, if any, or interest, if any, on Notes issued hereunder shall remain so deposited for a period of six years from the Redemption Date, then such funds shall at the end of such period be paid over or delivered over by the Trustee or such Paying Agent to the Corporation on its demand, and thereupon the Trustee shall not be responsible to Holders of such Notes for any amounts owing to them and subject to applicable law, thereafter the Holders of such Notes in respect of which such money was so repaid to the Corporation shall have no rights in respect thereof except to obtain payment of the money due from the Corporation, subject to any limitation period provided by the laws of Alberta.

4.9 Cancellation of Notes Redeemed

Subject to the provisions of Sections 4.4 and 4.10 as to Notes redeemed or purchased in part, all Notes redeemed and paid or purchased under this Article 4 shall forthwith be delivered to the Trustee and cancelled and no Notes shall be issued in substitution for those redeemed.

4.10 Purchase of Notes

(a) The Corporation may, at any time and from time to time, purchase Notes in the market (which shall include purchases from or through an investment dealer or a firm holding

53

membership on a recognized stock exchange), by private purchase, by tender, by contract or otherwise, in accordance with applicable securities laws, at any price, so long as no Default or Event of Default has occurred and is continuing and such acquisition does not otherwise violate the terms of this Indenture.

(b) If, upon an invitation for tenders, more Notes are tendered at the same lowest price than the Corporation is prepared to accept, the Notes to be purchased by the Corporation shall be selected by the Trustee on a pro rata basis or in such other manner as the Corporation directs in writing and as consented to by the exchange, if any, on which the Notes are then listed which the Trustee considers appropriate, from the Notes tendered by each tendering Holder thereof who tendered at such lowest price. For this purpose the Trustee may make, and from time to time amend, regulations with respect to the manner in which Notes may be so selected, and regulations so made shall be valid and binding upon all Holders thereof, notwithstanding the fact that as a result thereof one or more of such Notes become subject to purchase in part only. The Holder of a Note of which a part only is purchased, upon surrender of such Note for payment, shall be entitled to receive, without expense to such Holder, one or more new Notes for the unpurchased part so surrendered, and (i) in the case of Definitive Notes, the Corporation shall execute and, upon receipt by the Trustee of a Corporation Order, the Trustee shall authenticate and deliver without charge to the Holder thereof or upon the Holder’s order one or more new Notes for the unpurchased part of the principal amount of the Notes so surrendered an (ii) in the case of Global Notes, the Trustee shall make notations on the Global Notes (or in the case of uncertificated Global Notes, in accordance with the Trustee’s Internal Procedures) of the principal amount thereof so purchased.

Article 5
COVENANTS OF THE CORPORATION

As long as any Notes remain outstanding, the Corporation hereby covenants and agrees with the Trustee for the benefit of the Trustee and the Holders as follows:

5.1 Payment of Principal, Premium and Interest

(a) The Corporation covenants and agrees for the benefit of the Holders that it will duly and punctually pay the principal of, premium (if any) and interest on the Notes in accordance with the terms of the Notes and this Indenture.

(b) The Corporation shall pay interest on overdue principal and premium, if any, at the rate that is 1% higher than the then applicable interest rate on the Notes, and it will pay interest on overdue instalments of interest at the same rate to the extent lawful.

Subject to Article 9, the Corporation shall, and shall cause each Restricted Subsidiary to, do or cause to be done all things necessary to preserve and keep in full force and effect the corporate, partnership or other legal existence, as applicable, of the Corporation and each Restricted Subsidiary; provided that neither the Corporation nor any Restricted Subsidiary will be required to preserve any such corporate, partnership or other legal existence if the Board of Directors of the Corporation determines that the preservation thereof is no longer desirable in the conduct of the business of the Corporation and the Restricted Subsidiaries, taken as a whole, and that the loss thereof is not disadvantageous in any material respect to the Holders.

54

5.3 Payment of Taxes and Other Claims

The Corporation shall and shall cause each of the Restricted Subsidiaries to file all tax returns required to be filed in any jurisdiction and to pay and discharge, or cause to be paid and discharged, all Taxes shown to be due and payable on such returns and all other Taxes imposed on them or any of their properties, assets, income or franchises, to the extent such Taxes have become due and payable and before they have become delinquent and all claims for which sums have become due and payable that have or might become a Lien on the property or assets of the Corporation or any Restricted Subsidiary; provided that neither the Corporation nor any Restricted Subsidiary need pay any such Taxes or claim if (a) the amount, applicability or validity thereof is contested by the Corporation or such Restricted Subsidiary on a timely basis in good faith and in appropriate proceedings, and the Corporation or a Restricted Subsidiary has established adequate reserves therefor in accordance with GAAP on the books of the Corporation or such Restricted Subsidiary and/or (b) the non-payment of all such Taxes and/or claims in the aggregate would not reasonably be expected to have a material adverse effect on the business, affairs or financial condition of the Corporation and the Restricted Subsidiaries, taken as a whole.

5.4 Keeping of Books

The Corporation shall keep or cause to be kept, and shall cause each Restricted Subsidiary to keep or cause to be kept proper books of record and account, in which full and correct entries (in all material respects) shall be made of all financial transactions and the property and business of the Corporation and the Restricted Subsidiaries in accordance with GAAP.

5.5 Statement by Officers

For purposes of this Section 5.5(a), such compliance shall be determined without regard to any period of grace or requirement of notice under this Indenture.

(b) Upon becoming aware of any Default or Event of Default, the Corporation shall promptly (and in any event within ten Business Days) deliver to the Trustee an Officer’s Certificate specifying such event, notice or other action giving rise to such Default or Event of Default and the action that the Corporation or Restricted Subsidiary, as applicable, is taking or proposes to take with respect thereto.

Any such obligation to provide such Financial Reports shall continue in the event that the Corporation ceases to be a “reporting issuer” (or its equivalent) as if it had continued to be a “reporting issuer” (or its equivalent). Notwithstanding the foregoing, all Financial Reports will be deemed to have been provided to the Trustee and the Holders as required hereunder once filed on the System for Electronic Data Analysis and Retrieval+ (“SEDAR”).

(b) Unless the Financial Reports are available on SEDAR or any successor system thereto, the Corporation will also maintain a website to which the beneficial owners of the Notes are given free access and on which, not later than the date by which the Financial Reports

55

are required to be provided to the Trustee pursuant to Section 5.6(a), such Financial Reports are made available. Making such Financial Reports so available shall be deemed to satisfy the requirements of Section 5.6(a) that such Financial Reports be provided to the Trustee and delivered to the Holders.

5.7 Future Guarantors

If any Restricted Subsidiary (a) guarantees the obligations of the Corporation or becomes a borrower under the Credit Agreement, or (b) incurs or guarantees any other Indebtedness, which other Indebtedness exceeds $10,000,000 principal amount, then such Restricted Subsidiary will become a Guarantor by (i) executing and delivering to the Trustee a Subsidiary Guarantee and (ii) in the case of a guarantee or Indebtedness referred to in clause (a) or (b) that is incurred after the Issue Date, delivering an Opinion of Counsel satisfactory to the Trustee, in each case within 10 Business Days after the later of the Issue Date and the date such Restricted Subsidiary guaranteed or incurred such Indebtedness. In addition, a Restricted Subsidiary may elect at any time to become a Guarantor by executing and delivering to the Trustee a Subsidiary Guarantee and an Opinion of Counsel satisfactory to the Trustee.

5.8 Liens

The Corporation will not, and will not permit any of its Restricted Subsidiaries to, directly or indirectly, create, incur, assume or otherwise cause or suffer to exist or become effective any Lien (an “Initial Lien”) of any kind (other than Permitted Liens) securing Indebtedness upon or with respect to any of their property or assets, now owned or hereafter acquired, unless:

(a) in the case of Liens securing Subordinated Indebtedness, all payments due under this Indenture, the Notes and the Subsidiary Guarantees are secured by a Lien on such property or assets that is senior in priority to such Initial Liens; or

(b) in all other cases, all payments due under this Indenture, the Notes and the Subsidiary Guarantees are equally and ratably secured by a Lien on such property or assets, or are secured by a Lien on such property or assets that is senior in priority to such Initial Liens.

Any Lien created for the benefit of the Holders of the Notes pursuant to this Section 5.8 shall provide by its terms that such Lien shall be automatically and unconditionally released and discharged upon the release and discharge of the Initial Lien.

The Corporation will not, and will not permit any of its Restricted Subsidiaries to, directly or indirectly, pay or cause to be paid any consideration to or for the benefit of any Holder of Notes for or as an inducement to any consent, waiver or amendment of any of the terms or provisions of this Indenture or the Notes unless such consideration is offered to be paid and is paid to all Holders of the Notes that consent, waive or agree to amend in the time frame set forth in the solicitation documents relating to such consent, waiver or agreement.

(a) The Corporation will not, and will not permit any of its Restricted Subsidiaries to, directly or indirectly, create, incur, issue, assume, guarantee or otherwise become directly or indirectly liable, contingently or otherwise, with respect to (in any such case, “incur”) any Indebtedness, and the Corporation will not, and will not permit any of its Restricted Subsidiaries to, issue any Disqualified Stock, and the Corporation will not permit any of its Restricted Subsidiaries that is not a Guarantor to issue any Preferred Stock; provided, however, that the Corporation and any of its Restricted Subsidiaries may incur Indebtedness or issue Disqualified Stock, and a Restricted Subsidiary that is not a Guarantor may issue Preferred Stock, if in each case immediately after giving effect thereto, the Fixed Charge Coverage Ratio for the Corporation’s then most recently ended four full fiscal quarters for which annual or quarterly financial statements (whether internal or publicly disclosed) are available would have been at least 2.0 to 1.0, determined on a pro forma basis (including a pro forma application of the net proceeds therefrom), as if the additional Indebtedness had been incurred or the Disqualified Stock or Preferred Stock had been issued, as the case may be, at the beginning of such four-quarter period.

(b) Section 5.11(a) will not prohibit the incurrence of any of the following items of Indebtedness or issuances of Disqualified Stock or Preferred Stock, as applicable (collectively, “Permitted Debt”):

61

amount thereof) not to exceed the greater of (a) $235,000,000, (b) the Borrowing Base and (c) 35% of Adjusted Consolidated Net Tangible Assets, and in the case of (b) and (c), determined as of the date on which such additional Indebtedness is incurred, and after giving effect to the incurrence of such Indebtedness (and including any assets acquired with such Indebtedness), less (in the case of (a)) the aggregate amount of all Net Proceeds of Asset Sales applied by the Corporation or any of its Restricted Subsidiaries since the Issue Date to repay any term Indebtedness under a Credit Facility or to repay any revolving credit Indebtedness under a Credit Facility and effect a corresponding commitment reduction thereunder pursuant to Section 5.14;

(iii) the incurrence by the Corporation of Indebtedness represented by the Notes to be issued on the Issue Date and the incurrence by the Guarantors of Indebtedness represented by the Subsidiary Guarantees (and excluding, for the avoidance of doubt, any Additional Notes issued after the Issue Date);

(v) the incurrence by the Corporation or any of its Restricted Subsidiaries of Permitted Refinancing Indebtedness incurred in exchange for, or the net proceeds of which are used to renew, refund, refinance, replace, defease or discharge any Indebtedness (other than intercompany Indebtedness) that was permitted by this Indenture to be incurred under the first paragraph of this covenant or clauses (ii), (iii), (iv), (v), (xii), (xiv), (xvii) or (xix) of this Section 5.11(b);

(vi) the incurrence by the Corporation or any of its Restricted Subsidiaries of intercompany Indebtedness between or among the Corporation and any of its Restricted Subsidiaries; provided, however, that:

(A) if the Corporation or any Guarantor is the obligor on such Indebtedness and the payee is not the Corporation or a Guarantor, such Indebtedness must be unsecured and expressly subordinated to the prior payment in full in cash of all Obligations then due with respect to the Notes, in the case of the Corporation, or the applicable Subsidiary Guarantee, in the case of a Guarantor; and

(B) (i) any subsequent issuance or transfer of Equity Interests that results in any such Indebtedness being held by a Person other than the Corporation or any of its Restricted Subsidiaries, and (ii) any sale or other transfer of any such Indebtedness to a Person other than the Corporation or any of its Restricted Subsidiaries will be deemed, in each case, to constitute an incurrence of such Indebtedness by the Corporation or such Restricted Subsidiary, as the case may be, that was not permitted by this Section 5.11(b)(vi);

62

(vii) the incurrence by the Corporation or any of its Restricted Subsidiaries of Hedging Obligations, provided that such Hedging Obligations were not incurred for speculative purposes;

(c) For purposes of determining compliance with Section 5.11:

(i) in the event that an item of proposed Indebtedness meets the criteria of more than one of the categories of Permitted Debt described in Section 5.11(b)(i) through (b)(xix) above, or is entitled to be incurred pursuant to the first paragraph of this covenant, the Corporation will be permitted to divide and classify (or later redivide, classify or reclassify) such item of Indebtedness in whole or in part in any manner that complies with this covenant, including by allocation to more than one other type of Indebtedness, provided that all Indebtedness incurred pursuant to the Credit Agreement will be deemed to be incurred pursuant to Section 5.11(b)(i), and may not be reclassified pursuant to this Section 5.11(c);

(ii) Guarantees of, or obligations in respect of letters of credit relating to, Indebtedness which are otherwise included in the determination of a particular amount of Indebtedness shall not be included;

(iii) the amount of Indebtedness issued at a price that is less than the principal amount thereof will be equal to the amount of the liability in respect thereof determined in accordance with GAAP;

(iv) Indebtedness of any Person existing at the time such Person becomes a Restricted Subsidiary of the Corporation (or amalgamates, merges or consolidates with or into the Corporation or of its Restricted Subsidiaries) shall be deemed to have been incurred by a Restricted Subsidiary of the Corporation at the time such Person becomes a Restricted Subsidiary of the Corporation (or amalgamates, merges or consolidates with or into the Corporation or any of its Restricted Subsidiaries), provided that any Indebtedness of such Person that is redeemed, defeased, retired or otherwise repaid at the time of or immediately upon consummation of the transaction by which such Person becomes a Restricted Subsidiary of the Corporation (or amalgamates, merges or consolidates with or into the Corporation or any of its Restricted Subsidiaries) will be deemed to not be Indebtedness for the purposes of this covenant; and

64

(v) the accrual of interest or Preferred Stock dividends, the accretion or amortization of original issue discount, the payment of interest on any Indebtedness in the form of additional Indebtedness with the same terms, the payment of dividends on any Preferred Stock in the form of (A) additional Preferred Stock with the same terms or (B) increases to the underlying principal amount or equivalent of already issued Preferred Stock, the reclassification of Preferred Stock as Indebtedness due to a change in accounting principles, and the payment of dividends on Disqualified Stock or Preferred Stock in the form of additional shares of the same class of Disqualified Stock or Preferred Stock will not be deemed to be an incurrence of Indebtedness or an issuance of Disqualified Stock or Preferred Stock for purposes of this covenant; provided, in each such case, that the amount thereof is included in Fixed Charges of the Corporation as accrued.

(d) For purposes of determining compliance with any Canadian dollar-denominated restriction on the incurrence of Indebtedness, the Canadian dollar-equivalent principal amount of Indebtedness denominated in a foreign currency shall be calculated based on the relevant currency exchange rate in effect on the date such Indebtedness was incurred, in the case of term Indebtedness, or first committed, in the case of revolving credit Indebtedness; provided that if such Indebtedness is incurred to refinance other Indebtedness denominated in a foreign currency, and such refinancing would cause the applicable Canadian dollar-denominated restriction to be exceeded if calculated at the relevant currency exchange rate in effect on the date of such refinancing, such Canadian dollar-denominated restriction shall be deemed not to have been exceeded so long as the principal amount of such refinancing Indebtedness does not exceed the principal amount of such Indebtedness being refinanced. Notwithstanding any other provision of this covenant, the maximum amount of Indebtedness that the Corporation may incur pursuant to this covenant shall not be deemed to be exceeded solely as a result of fluctuations in the exchange rate of currencies. The principal amount of any Permitted Refinancing Indebtedness, if incurred in a different currency from the Indebtedness being refinanced, shall be calculated based on the currency exchange rate applicable to the currencies in which such Permitted Refinancing Indebtedness is denominated that is in effect on the date of such refinancing.

(e) Neither the Corporation nor any Guarantor will incur any additional Indebtedness (including Permitted Debt (other than under Section 5.11(b)(v))) that is contractually subordinated in right of payment to any other Indebtedness of such Person unless such additional Indebtedness is also contractually subordinated in right of payment to the Notes or the applicable Subsidiary Guarantee, as the case may be, on substantially identical terms; provided, however, that no Indebtedness will be deemed to be contractually subordinated in right of payment to any other Indebtedness solely by virtue of being unsecured.

5.12 Dividend and Other Payment Restrictions Affecting Restricted Subsidiaries

(a) The Corporation will not, and will not permit any of its Restricted Subsidiaries to, directly or indirectly, create or permit to exist or become effective any consensual encumbrance or restriction on the ability of any of its Restricted Subsidiaries to:

(i) pay dividends or make any other distributions on its Capital Stock to the Corporation or any of its Restricted Subsidiaries or pay any Indebtedness owed to the Corporation or any of its Restricted Subsidiaries; provided that the priority of any Preferred Stock over common stock in receiving dividends or liquidating distributions shall not be deemed a restriction on the ability to make distributions on Capital Stock;

(ii) make loans or advances to the Corporation or any of its Restricted Subsidiaries; or

65

(iii) sell, lease or transfer any of its properties or assets to the Corporation or any of its Restricted Subsidiaries.

(ii) this Indenture, the Notes and the Subsidiary Guarantees;

(iii) applicable law, rule, regulation, order, approval, license, permit or similar restriction;

(iv) agreements governing other Indebtedness permitted to be incurred under the provisions of Section 5.11 and any amendments, restatements, modifications, renewals, supplements, replacements or refinancings of those agreements; provided that the encumbrances and restrictions therein will not materially adversely impact the ability of the Corporation to make required principal (and premium, if any) and interest payments on the Notes;

(v) any instrument governing Indebtedness or Capital Stock of a Person acquired by the Corporation or any of its Restricted Subsidiaries as in effect at the time of such acquisition (except to the extent such Indebtedness or Capital Stock was incurred in connection with or in contemplation of such acquisition), which encumbrance or restriction is not applicable to any Person, or the properties or assets of any Person, other than the Person, or the property or assets of the Person, so acquired, provided that, in the case of Indebtedness, such Indebtedness was permitted by the terms of this Indenture to be incurred;

(vi) non-assignment provisions in contracts and leases entered into in the ordinary course of business;

(vii) Purchase Money Obligations or other similar mortgage financings permitted to be incurred under the provisions of Section 5.11, in each case, for property acquired in the ordinary course of business and Capital Lease Obligations and that impose restrictions on that property of the nature under Section 5.12(a)(iii);

(viii) any agreement (a) for the sale or other disposition of Capital Stock or assets of a Restricted Subsidiary of the Corporation that restricts distributions by that Restricted Subsidiary or sales of such Restricted Subsidiary’s property and assets pending its sale or other disposition or (b) for the sale of a particular asset or line of business of a Restricted Subsidiary of the Corporation that imposes restrictions on property subject to an agreement of the nature under Section 5.12(a)(iii);

(ix) Permitted Refinancing Indebtedness, including any encumbrances or restrictions imposed by any amendments or refinancings of the contracts, instruments and

66

Obligations referred to in this covenant, provided that the restrictions contained in the agreements governing such Permitted Refinancing Indebtedness (taken as a whole) are not materially more restrictive (as determined in good faith by the Corporation) than those contained in the agreements governing the Indebtedness being refinanced (taken as a whole);

(x) agreements existing on the Issue Date;

(xi) Permitted Liens that limit the right of the debtor to dispose of the assets subject to such Liens;

(xii) provisions with respect to the leasing, subleasing or disposition or distribution of assets, ownership interests or property in joint venture agreements, partnership agreements, shareholder agreements, asset sale agreements, sale lease-back agreements, stock sale agreements, farm-in and farm-out agreements and other similar agreements entered into in the ordinary course of business which limitation is applicable only to the assets that are the subject of such agreements;

(xiii) any other agreement governing Indebtedness permitted to be incurred under the provisions of Section 5.11, or other obligations, in each case entered into after the Issue Date, that either (A) contains encumbrances and restrictions, taken as a whole, that are not materially more restrictive, as determined in good faith by the Corporation, with respect to any Restricted Subsidiary than those in effect on the Issue Date with respect to that Restricted Subsidiary, taken as a whole, pursuant to agreements in effect on the Issue Date or (B) contains any such encumbrance or restriction that is customary and does not prohibit (except upon a default or an event of default thereunder) the payment of dividends in an amount sufficient, as determined by the Corporation in good faith, to make scheduled payments of cash interest and principal on the Notes when due;

(xiv) restrictions on cash, Cash Equivalents or other deposits or net worth imposed by customers under contracts entered into in the ordinary course of business;

(xv) encumbrances and restrictions contained in contracts entered into in the ordinary course of business, not relating to any Indebtedness, and that do not, individually or in the aggregate, detract from the value of, or from the ability of the Corporation and any of its Restricted Subsidiaries to realize the value of, property or assets of the Corporation or any of its Restricted Subsidiaries in any manner material to the Corporation or any of its Restricted Subsidiaries; and

(xvi) any encumbrance or restriction with respect to a Restricted Subsidiary of the Corporation pursuant to or by reason of an agreement that such Restricted Subsidiary entered into at a time when such Restricted Subsidiary was an Unrestricted Subsidiary; provided that such agreement was not entered into in anticipation of the Unrestricted Subsidiary becoming a Restricted Subsidiary and any such encumbrance or restriction shall not extend to any assets or property of the Corporation or any Restricted Subsidiary of the Corporation other than such Restricted Subsidiary.

5.13 Transactions with Affiliates

(a) The Corporation will not, and will not permit any of its Restricted Subsidiaries to, make any payment to, or sell, lease, transfer or otherwise dispose of any of its properties or assets to, or purchase any property or assets from, or enter into or make or amend any transaction, contract, agreement, understanding, loan, advance or Guarantee with, or for

67

the benefit of, any Affiliate of the Corporation (each, an “Affiliate Transaction”), unless the Affiliate Transaction is on terms that are no less favourable in the aggregate to the Corporation or the relevant Restricted Subsidiary than those that could have reasonably been expected to have been obtained in a comparable transaction at such time by the Corporation or such Restricted Subsidiary in an arm’s-length dealing with a Person who is not an Affiliate of the Corporation; provided that, in the case of an Affiliate Transaction or series of related Affiliate Transactions where the aggregate consideration exceeds $20,000,000, such determination shall be made in good faith by the Chief Financial Officer of the Corporation and confirmed in an Officer’s Certificate delivered to the Trustee.

(b) The following items will be deemed not to be Affiliate Transactions and, therefore, will not be subject to Section 5.13(a):

(i) any employment agreement, consulting agreement or other employee, director or officer compensation plan, benefit plan or expense reimbursement, indemnification or severance agreement or similar arrangement existing on the Issue Date or thereafter entered into by the Corporation or any of its Restricted Subsidiaries in the ordinary course of business and consistent with the past practice of the Corporation or such Restricted Subsidiary or approved by the Board of Directors of the Corporation (including, in each case, payments thereunder in accordance with the terms thereof);

(ii) transactions between or among the Corporation and/or its Restricted Subsidiaries;

(iii) transactions with a Person (other than an Unrestricted Subsidiary) that is an Affiliate of the Corporation solely because the Corporation owns, directly or through a Restricted Subsidiary, an Equity Interest in, or controls, such Person;

(iv) the entering into of a tax sharing agreement, or payments pursuant thereto, between the Corporation and/or one or more Subsidiaries, on the one hand, and any other Person with which the Corporation or such Subsidiaries are required or permitted to file a consolidated tax return or with which the Corporation or such Subsidiaries are part of a consolidated group for tax purposes to be used by such Person to pay taxes, and which payments by the Corporation and the Restricted Subsidiaries are not in excess of the tax liabilities that would have been payable by them on a stand-alone basis;

(v) any Affiliate Transaction or series of related Affiliate Transactions involving aggregate consideration of less than $20,000,000;

(vi) the issuance or sale of Equity Interests (other than Disqualified Stock or warrants, options or other rights to acquire Disqualified Stock) of the Corporation to, or the receipt by the Corporation of any capital contribution from, its shareholders or Affiliates, and the granting of registration and other customary rights in connection therewith;

(vii) Restricted Payments that are permitted under Section 5.10 and Permitted Investments made in reliance on clause (18) of the definition of Permitted Investments;

(viii) the performance of obligations of the Corporation or any of its Restricted Subsidiaries under the terms of any agreement to which the Corporation or any of its Restricted Subsidiaries is a party as of or on the Issue Date, as each such agreement may be amended, modified, supplemented, extended or renewed from time to time; provided, however, that any future amendment, modification,

68

supplement, extension or renewal entered into after the Issue Date will be permitted to the extent that its terms are not materially more disadvantageous, taken as a whole (in the reasonable determination of the Corporation), to the Holders of the Notes than the terms of the relevant agreements in effect on the Issue Date;

(ix) transactions between the Corporation or any of its Restricted Subsidiaries and any Person, a director of which is also a director of the Corporation or any direct or indirect parent company of the Corporation and such cross-directorship is the sole cause for such Person to be deemed an Affiliate of the Corporation or any of its Restricted Subsidiaries; provided, however, that such director shall abstain from voting as a director of the Corporation or such direct or indirect parent company, as the case may be, on any matter involving such other Person;

(x) transactions with joint venture partners of the Corporation or its Restricted Subsidiaries, in each case in the ordinary course of business of the Corporation and its Restricted Subsidiaries and otherwise in compliance with the terms of this Indenture; provided that in the reasonable determination of a responsible senior officer of the Corporation or the relevant Restricted Subsidiary, as applicable, such transactions are on terms that are no less favourable to the Corporation or such Restricted Subsidiary than those that would have been obtained in a comparable transaction by the Corporation or such Restricted Subsidiary with an unrelated Person;

(xi) transactions entered into in good faith with an Affiliate of the Corporation or any of its Restricted Subsidiaries that provide for shared services and/or facilities arrangements and that provide cost savings and/or other operational efficiencies to the Corporation or any of its Restricted Subsidiaries as determined in good faith the Corporation, and payments related thereto;

(xii) any agreement between any Person and an Affiliate of such Person existing at the time such Person is acquired by, merged into or amalgamated, arranged or consolidated with the Corporation or any of its Restricted Subsidiaries and any amendment thereto; provided that such agreement was not entered into in contemplation of such acquisition, merger, amalgamation, arrangement or consolidation and any amendment thereto and that any such amendment is not disadvantageous to the holders of the Notes, taken as a whole, as compared to the applicable agreement as in effect on the date of such acquisition, merger, amalgamation, plan of arrangement or consolidation; and

(xiii) (a) Guarantees of performance by the Corporation and its Restricted Subsidiaries of the Corporation’s Unrestricted Subsidiaries in the ordinary course of business, except for Guarantees of Indebtedness, and (b) the incurrence of Non-Recourse Debt.

5.14 Asset Sales

(a) The Corporation will not, and will not permit any of its Restricted Subsidiaries to, consummate an Asset Sale unless:

(i) the Corporation (or the Restricted Subsidiary, as the case may be) receives consideration at the time of the Asset Sale at least equal to the Fair Market Value (including as to the value of all non-cash consideration, and measured as of the date of the definitive agreement with respect to such Asset Sale) of the assets, properties or Equity Interests issued or sold or otherwise disposed of; and

69

(ii) at least 75% of the consideration received in the Asset Sale by the Corporation or such Restricted Subsidiary is in the form of cash, Cash Equivalents, Liquid Securities or Permitted Assets. For purposes of this provision, each of the following will be deemed to be cash:

(A) any liabilities, as shown on the Corporation’s or such Restricted Subsidiary’s most recent balance sheet, of the Corporation or any of its Restricted Subsidiaries (other than contingent liabilities and liabilities that are by their terms subordinated to the Notes or any Subsidiary Guarantee) that are assumed by the transferee of any such assets pursuant to a customary novation agreement or similar agreement that releases the Corporation or such Restricted Subsidiary from further liability;

(B) any securities, notes or other obligations received by the Corporation or any such Restricted Subsidiary in such Asset Sale that are converted within 180 days by the Corporation or such Restricted Subsidiary into cash or Cash Equivalents, to the extent of the cash or Cash Equivalents received in that conversion;

(C) any Designated Non-cash Consideration received by the Corporation or any of its Restricted Subsidiaries in such Asset Sale, having an aggregate Fair Market Value, taken together with all other Designated Non-cash Consideration received pursuant to this clause (C) (without giving effect to subsequent changes in value that is at the time outstanding), not to exceed 10% of Adjusted Consolidated Net Tangible Assets measured at the time the determination is made;

(D) accounts receivable of a business retained by the Corporation or any of its Restricted Subsidiaries, as the case may be, following the sale of such business, provided that such accounts receivable are (i) not past due more than 90 days and (ii) collected within 120 days from the date of the invoice creating such accounts receivable; and

(E) with respect to any Asset Sale of any Oil and Gas Properties in the ordinary course of business where the Corporation or any Restricted Subsidiary retains an interest in such property, the portion of any costs and expenses related to the exploration, development, completion or production of such Oil and Gas Properties and activities related thereto that would be attributable to the Corporation’s retained interest in such property, to the extent that such costs and expenses are agreed to be assumed by the transferee or its Affiliate pursuant to a customary agreement, and are paid by the transferee or its Affiliate, as the case may be, in cash within 180 days of such Asset Sale.

Any Asset Sale pursuant to а condemnation, expropriation, appropriation or other similar taking, including by deed in lieu of condemnation, shall not be required to satisfy the conditions set forth in Section 5.14(a)(i).

(b) Within 365 days after the receipt of any Net Proceeds from an Asset Sale, the Corporation or any Restricted Subsidiary may apply those Net Proceeds to any, or any combination, of the following purposes:

(i) to repay, prepay, redeem, purchase or repurchase (in any case on a permanent basis) Secured Debt of the Corporation or any of its Restricted Subsidiaries and, if the Secured Debt repaid is revolving credit Indebtedness, to correspondingly permanently reduce commitments with respect thereto;

70

(ii) to acquire all or substantially all of the assets of, or a majority of the Capital Stock of, another Person engaged in an Energy Business that, in the case of an acquisition of Capital Stock, becomes a Restricted Subsidiary of the Corporation as a result of such acquisition, or to acquire additional Capital Stock in any Person that at such time is a Restricted Subsidiary of the Corporation;

(iii) to make a capital expenditure;

(iv) to repurchase any Notes; or

(v) to acquire other Permitted Assets.

(c) Notwithstanding the foregoing, in the event that the Corporation or any of its Restricted Subsidiaries enters into a binding agreement committing to take any of the actions under Section 5.14(b)(ii) through Section 5.14(b)(v) within 365 days after the receipt of any Net Proceeds from an Asset Sale, such commitment will be treated as a permitted application of the Net Proceeds from the date of the execution of such agreement until the earlier of (i) the date on which such acquisition or investment is consummated or such expenditure made or such agreement is terminated, and (ii) the 180th day after entering into such binding agreement.

(d) Pending the final application of any Net Proceeds, the Corporation may temporarily reduce revolving credit borrowings or otherwise invest the Net Proceeds in any manner that is not prohibited by this Indenture.

(e) Any Net Proceeds from Asset Sales that are not applied or invested as provided in Section 5.14(b) and Section 5.14(d) will constitute “Excess Proceeds”.

(f) On the 366th day after the Asset Sale (or, at the Corporation’s option, any earlier date), if the aggregate amount of Excess Proceeds exceeds $30,000,000, the Corporation will make a pro rata offer (an “Asset Sale Offer”) to all Holders of Notes and all holders of other Indebtedness that ranks pari passu in right of payment with the Notes containing provisions similar to those set forth in this Indenture with respect to offers to purchase or redeem with the proceeds of sales of assets, to purchase the maximum principal amount of Notes and such other pari passu Indebtedness that may be purchased out of the Excess Proceeds. The offer price in any Asset Sale Offer will be equal to 100% of the principal amount (or accreted value in the case of any such other pari passu Indebtedness issued with a significant original issue discount) plus accrued and unpaid interest, if any, to the date of purchase, and will be payable in cash. If the aggregate principal amount of Notes and other pari passu Indebtedness tendered into such Asset Sale Offer exceeds the amount of Excess Proceeds allocated for repurchases of Notes pursuant to the Asset Sale Offer, the Trustee will select the Notes and such other pari passu Indebtedness to be purchased on a pro rata basis (subject to the procedures of the relevant depository), on the basis of the aggregate principal amounts (or accreted values) tendered in round denominations (which in the case of the Notes will be minimum denominations of $2,000 principal amount or multiples of $1,000 in excess thereof). If any Excess Proceeds remain after consummation of an Asset Sale Offer, the Corporation may use those Excess Proceeds for any purpose not otherwise prohibited by this Indenture. Upon completion of each Asset Sale Offer, the amount of Excess Proceeds will be reset at zero.

(g) If the Asset Sale Offer purchase date is on or after a Record Date and on or before the related Interest Payment Date, any accrued and unpaid interest will be paid to the Person in whose name a Note is registered at the close of business on such Record Date, and no other interest will be payable to Holders who tender Notes pursuant to the Asset Sale Offer.

71

(h) Within ten Business Days after the Corporation is obligated to make an Asset Sale Offer as described in the preceding paragraphs, the Corporation will send a written notice, by first-class mail, to the Holders, accompanied by such information regarding the Corporation and its Subsidiaries as the Corporation in good faith believes will enable such Holders to make an informed decision with respect to such Asset Sale Offer. Such notice shall state, among other things, the purchase price and the purchase date, which shall be, subject to any contrary requirements of applicable law, a Business Day no earlier than 10 days nor later than 60 days from the date such notice is mailed.

(i) Notwithstanding the foregoing provisions of this Section 5.14, the sale, conveyance or other disposition of all or substantially all of the assets of the Corporation and its Restricted Subsidiaries, taken as a whole, will be governed by Section 5.15 and/or Article 9 and will not be subject to this Section 5.14.

(j) The Corporation will comply with the requirements of Applicable Securities Legislation to the extent those laws and regulations are applicable in connection with each repurchase of Notes pursuant to an Asset Sale Offer. To the extent that the provisions of any Applicable Securities Legislation conflict with this Section 5.14 or compliance with this Section 5.14 would constitute a violation of any such laws or regulations, the Corporation will comply with the Applicable Securities Legislation and regulations and will not be deemed to have breached its obligations under this Section 5.14 by virtue of such conflict.

(k) The Credit Agreement prohibits, and any future credit agreements or other similar agreements to which the Corporation becomes a party may prohibit, the Corporation from purchasing any Notes, and also provides that certain asset sale events with respect to the Corporation would constitute a default thereunder. In the event an Asset Sale occurs at a time when the Corporation is prohibited from purchasing Notes, the Corporation could seek the consent of its lenders to the purchase of Notes or could attempt to refinance the borrowings that contain such prohibition. If the Corporation does not obtain such a consent or repay such borrowings, the Corporation will remain prohibited from purchasing Notes. In such case, the Corporation’s failure to purchase tendered Notes would constitute an Event of Default under this Indenture which would, in turn, constitute a default under such other agreements. In addition, the exercise by the Holders of Notes of their right to require the Corporation to repurchase the Notes upon an Asset Sale could cause a default under these other agreements, even if the Asset Sale itself does not, due to the financial effect of such repurchase on the Corporation. Finally, the Corporation’s ability to pay cash to the holders of Notes upon a repurchase may be limited by the Corporation’s then existing financial resources.

5.15 Offer to Repurchase on a Change of Control

(a) If a Change of Control Triggering Event occurs, unless the Corporation has previously exercised its right to redeem all of the Notes under Section 4.1, each Holder will have the right to require the Corporation to repurchase all or any part (equal to $2,000 or an integral multiple of $1,000 in excess thereof) of each Holder’s Notes pursuant to an offer on the terms set forth in this Indenture (the “Change of Control Offer”). In the Change of Control Offer, the Corporation will offer a payment (the “Change of Control Payment”) in cash equal to not less than 101% of the aggregate principal amount of Notes repurchased plus accrued and unpaid interest, if any, on the Notes repurchased, to but excluding the date of purchase (the “Change of Control Payment Date”).

(b) Within 30 days following any Change of Control Triggering Event, the Corporation will mail a notice to each Holder describing the transaction or transactions that constitute the Change of Control Triggering Event and offering to repurchase Notes on the Change of Control Payment Date specified in the notice, which date will be no earlier than 10 days and no later than 60 days from the date such notice is mailed, pursuant to the procedures

72

required by this Indenture and described in such notice. The Corporation will comply with the requirements of Applicable Securities Legislation to the extent those laws and regulations are applicable in connection with the repurchase of the Notes as a result of a Change of Control Triggering Event. To the extent that the provisions of any Applicable Securities Legislation conflict with the Change of Control Triggering Event provisions of this Indenture, the Corporation will comply with the Applicable Securities Legislation and will not be deemed to have breached its obligations under the Change of Control provisions of this Indenture by virtue of such conflict.

(c) On the Change of Control Payment Date, the Corporation or its designated agent will, to the extent lawful:

(i) accept for payment all Notes or portions of Notes (equal to $2,000 or an integral multiple of $1,000 in excess thereof) properly tendered pursuant to the Change of Control Offer;

(ii) deposit with the paying agent an amount equal to the Change of Control Payment in respect of all Notes or portions of Notes properly tendered; and

(iii) deliver or cause to be delivered to the Trustee the Notes accepted together with an Officer’s Certificate stating the aggregate principal amount of Notes or portions of Notes being purchased by the Corporation.

(d) On the Change of Control Payment Date, the paying agent will promptly mail to each Holder of Notes properly tendered and not withdrawn the Change of Control Payment for such tendered Notes, with such payment to be made through the facilities of the Depository for all Notes in global form, and the Trustee will promptly authenticate and mail (or cause to be transferred by book entry) to each Holder a new Note equal in principal amount to any unpurchased portion of the Notes surrendered, if any; provided that each new Note will be in a principal amount of $2,000 or an integral multiple of $1,000 in excess thereof.

(e) If the Change of Control Payment Date is on or after a Record Date and on or before the related Interest Payment Date, any accrued and unpaid interest will be paid to the Person in whose name a Note is registered at the close of business on such Record Date, and no other interest will be payable to Holders who tender pursuant to the Change of Control Offer.

(f) The Corporation will publicly announce the results of the Change of Control Offer on or as soon as practicable after the Change of Control Payment Date.

(g) The provisions in this Section 5.15 that require the Corporation to make a Change of Control Offer following a Change of Control Triggering Event will be applicable whether or not any other provisions of this Indenture are applicable. Except as described above with respect to a Change of Control Triggering Event, this Indenture does not contain provisions that permit the Holders of the Notes to require that the Corporation repurchase or redeem the Notes in the event of a takeover, recapitalization or similar transaction.

(h) The Credit Agreement provides that the occurrence of certain change of control events with respect to the Corporation would constitute a default thereunder. In the event a Change of Control occurs at a time when the Corporation is prohibited from purchasing Notes, the Corporation may seek the consent of its lenders to the purchase of Notes or may attempt to refinance the borrowings that contain such prohibition. If the Corporation does not obtain such a consent or repay such borrowings, it will remain prohibited from purchasing Notes. In such case, the Corporation’s failure to offer to purchase Notes would

73

constitute a Default under this Indenture, which would, in turn, constitute a default under the Credit Agreement.

(i) Future Indebtedness that the Corporation may incur may contain prohibitions on the occurrence of certain events that would constitute a Change of Control or require the repurchase of such Indebtedness upon a Change of Control. Moreover, the exercise by the Holders of their right to require the Corporation to repurchase their Notes could cause a default under such Indebtedness, even if the Change of Control Triggering Event itself does not, due to the financial effect of such repurchase on the Corporation. Furthermore, the Corporation’s ability to pay cash to the Holders of Notes following the occurrence of a Change of Control Triggering Event may be limited by its then existing financial resources. There can be no assurance that sufficient funds will be available when necessary to make any required repurchases.

(j) Notwithstanding the preceding provisions of this Section 5.15, the Corporation will not be required to make a Change of Control Offer upon a Change of Control Triggering Event and a Holder will not have the right to require the Corporation to repurchase any Notes pursuant to a Change of Control Offer if (a) a third party makes an offer to purchase the Notes in the manner, at the times and otherwise in substantial compliance with the requirements set forth in this Indenture applicable to a Change of Control Offer made by the Corporation (it being understood, for the avoidance of doubt, that such an offer by a third party shall be deemed to be a “Change of Control Offer” under this Indenture) and purchases all Notes validly tendered and not withdrawn under such Change of Control Offer, (b) a notice of redemption has been given pursuant to this Indenture under Section 4.1, unless and until there is a default in payment of the applicable redemption price. Notwithstanding anything to the contrary contained herein, a Change of Control Offer by the Corporation or a third party may be made in advance of a Change of Control Triggering Event, conditioned upon the consummation of such Change of Control, if a definitive agreement is in place for the Change of Control at the time the Change of Control Offer is made.

(k) In the event that Holders of not less than 90% of the aggregate principal amount of the outstanding Notes accept a Change of Control Offer and the Corporation (or any third party making such Change of Control Offer as described above) purchases all of the Notes held by such Holders, the Corporation (or such third party) will have the right, upon not less than 10 days’ nor more than 60 days’ prior notice, given not more than 30 days following the purchase pursuant to the Change of Control Offer described above, to redeem all of the Notes that remain outstanding following such purchase at a redemption price equal to the Change of Control Payment plus, to the extent not included in the Change of Control Payment, accrued and unpaid interest on the Notes that remain outstanding, to the date of redemption (subject to the right of Holders of record on the relevant Record Date to receive interest due on an Interest Payment Date that is on or prior to the redemption date).

5.16 Changes in GAAP

Each accounting term used in this Indenture, unless otherwise defined herein, has the meaning assigned to it under GAAP applied consistently throughout the relevant period and relevant prior periods.

(a) If there occurs a material change in GAAP after the Issue Date, and such change would require disclosure under GAAP in the financial statements of the Corporation and would cause an amount required to be determined for the purposes of any of the financial calculations or financial terms under this Indenture (each a “Financial Term”) to be materially different than the amount that would be determined without giving effects to such change, the Corporation shall notify the Trustee of such change (an “Accounting Change”). Such notice (an “Accounting Change Notice”) shall describe the nature of the

74

Accounting Change, its effect on the Corporation’s current and immediately prior year’s financial statements in accordance with GAAP and state whether the Corporation desires to revise the method of calculating the applicable Financial Term (including the revision of any of the defined terms used in the determination of such Financial Term) in order that amounts determined after giving effect to such Accounting Change and the revised method of calculating such Financial Term will approximate the amount that would be determined without giving effect to such Accounting Change and without giving effect to the revised method of calculating such Financial Term. The Accounting Change Notice shall be delivered to the Trustee within 60 days of the end of the fiscal quarter in which the Accounting Change is implemented or, if such Accounting Change is implemented in the fourth fiscal quarter or in respect of an entire fiscal year, within 120 days of the end of such period. Promptly after receipt from the Corporation of an Accounting Change Notice the Trustee shall deliver to each Holder a copy of such notice.

(b) If the Corporation so indicates that it wishes to revise the method of calculating the Financial Term, the Corporation shall in good faith provide to the Trustee the revised method of calculating the Financial Term within 90 days of the Accounting Change Notice, and such revised method shall take effect from the date of the Accounting Change Notice. For certainty, if no notice of a desire to revise the method of calculating the Financial Term in respect of an Accounting Change is given by the Corporation within the applicable time period under Section 5.16(a), the method of calculating the Financial Term shall not be revised in response to such Accounting Change, and all amounts to be determined pursuant to the Financial Term shall be determined after giving effect to such Accounting Change.

5.17 Financial Calculations for Limited Condition Acquisitions

When calculating the availability under any basket or ratio under the Indenture, in each case in connection with a Limited Condition Acquisition and the incurrence or issuance of Indebtedness, Disqualified Stock, Preferred Stock or Liens in connection therewith and the use of proceeds thereof, the date of determination of such basket or ratio and of any Default or Event of Default may, at the option of the Corporation, be the date the definitive agreement(s) for such Limited Condition Acquisition is entered into. Any such ratio or basket shall be calculated on a pro forma basis, including with such adjustments as are appropriate and consistent with the pro forma adjustment provisions set forth in the definition of "Fixed Charge Coverage Ratio", after giving effect to such Limited Condition Acquisition and the incurrence or issuance of Indebtedness, Disqualified Stock, Preferred Stock or Liens in connection therewith and the use of proceeds thereof, as if they had been consummated at the beginning of the applicable test period for purposes of determining the ability to consummate any such Limited Condition Acquisition; provided that if the Corporation elects to make such determination as of the date of such definitive agreement(s), then (a) the Corporation shall be deemed to be in compliance with such ratios or baskets solely for purposes of determining whether the Limited Condition Acquisition and the incurrence or issuance of Indebtedness, Disqualified Stock, Preferred Stock or Liens in connection therewith and the use of proceeds thereof, are permitted under the Indenture, and (b) such ratios or baskets shall not be tested at the time of consummation of such Limited Condition Acquisition or related transactions; provided, further, that if the Corporation elects to have such determinations occur at the time of entry into such definitive agreement(s), any such transactions (including any incurrence or issuance of Indebtedness, Disqualified Stock, Preferred Stock or Liens and the use of proceeds thereof) shall be deemed to have occurred on the date the definitive agreement(s) is entered into and, except for those calculations specifically described in the proviso below, shall be deemed outstanding thereafter for purposes of calculating any ratios or baskets under the Indenture after the date of such definitive agreement(s) and before the consummation of such Limited Condition Acquisition, unless such definitive agreement(s) is terminated or such Limited Condition Acquisition or incurrence or issuance of Indebtedness, Disqualified Stock, Preferred Stock or Liens for which pro forma effect is being given does not occur; provided further, that solely for purposes of determining the amount available for Restricted Payments under Section 5.10(a)(iv)(C)(1), no pro forma adjustments will be made under this Section 5.17 to Consolidated Net Income.

75

5.18 Covenants Termination

(a) If at any time, (a) the Notes have an Investment Grade Rating from at least 50% of the Designated Rating Organizations that have provided ratings of the Notes, and (b) no Default has occurred and is continuing, the Corporation and its Restricted Subsidiaries will not be subject to the provisions of this Indenture described under:

(A) Section 5.10;

(B) Section 5.11;

(C) Section 5.12;

(D) Section 5.13;

(E) Section 5.14; and

(F) Section 9.1(a)(iv).

Upon the termination of the covenants described above in the manner described above, the issuer will no longer be permitted to designate any Restricted Subsidiary as an Unrestricted Subsidiary.

5.19 Designation of Restricted and Unrestricted Subsidiaries

(a) The Board of Directors of the Corporation may designate any of its Restricted Subsidiaries to be an Unrestricted Subsidiary, provided that:

(i) immediately after and giving effect to such designation, no Default or Event of Default shall have occurred and be continuing;

(ii) the Fair Market Value of all outstanding Investments owned by the Corporation and its Restricted Subsidiaries in the Subsidiary so designated will be deemed to be an Investment made as of the time of the designation, and that such Investment would be permitted in compliance with Section 5.10;

(iii) at the time of such designation, such Subsidiary has no Indebtedness other than (i) Non-Recourse Debt, (ii) Indebtedness guaranteed pursuant to Non-Recourse Equity Pledge Debt, and (iii) Indebtedness that could be guaranteed by the Corporation in compliance with Section 5.10 (and the amount of any such existing Indebtedness under this clause (iii) shall be deemed to be an Investment by the Corporation for purposes of Section 5.10);

(iv) such Subsidiary is not party to any agreement, contract, arrangement or understanding with the Corporation or any Restricted Subsidiary of the Corporation unless the terms of any such agreement, contract, arrangement or understanding are not materially less favorable in the aggregate to the Corporation or such Restricted Subsidiary than those that might be obtained at the time from Persons who are not Affiliates of the Corporation; and

(v) such Subsidiary is a Person with respect to which neither the Corporation nor any of its Restricted Subsidiaries has any direct or indirect obligation (i) to subscribe for additional Equity Interests or (ii) to maintain or preserve such Person’s financial condition or to cause such Person to achieve any specified levels of operating results.

76

(b) Any designation of a Subsidiary of the Corporation as an Unrestricted Subsidiary will be evidenced to the Trustee by filing with the Trustee a certified copy of the resolutions of the Board of Directors of the Corporation giving effect to such designation and an Officer’s Certificate certifying that such designation complied with the preceding conditions. If, at any time, any Unrestricted Subsidiary would fail to meet the preceding requirements as an Unrestricted Subsidiary, it will thereafter cease to be an Unrestricted Subsidiary for purposes of this Indenture, and any Indebtedness of such Subsidiary will be deemed to be incurred by a Restricted Subsidiary as of such date and, if such Indebtedness is not permitted to be incurred as of such date under Section 5.11, the Corporation will be in default of such covenant.

(c) The effect of designating a Subsidiary as an Unrestricted Subsidiary will be that:

(i) an Unrestricted Subsidiary will not be subject to any of the restrictive covenants in this Indenture;

(ii) a Subsidiary that is a Guarantor and is subsequently designated as an Unrestricted Subsidiary will be released from its Subsidiary Guarantee; and

(iii) the assets, income, cash flow and other financial results of an Unrestricted Subsidiary will not be consolidated with those of the Corporation and its Restricted Subsidiaries for purposes of calculating compliance with the restrictive covenants contained in this Indenture.

(d) The Board of Directors of the Corporation may designate any Unrestricted Subsidiary to be a Restricted Subsidiary, provided that:

(i) immediately after giving effect to such designation, no Default or Event of Default shall have occurred and be continuing;

(ii) such designation will be deemed to be an incurrence of Indebtedness by a Restricted Subsidiary of any outstanding Indebtedness of such Unrestricted Subsidiary (and such designation will only be permitted if such Indebtedness is permitted under Section 5.11, calculated on a pro forma basis as if such designation had occurred at the beginning of the four-quarter reference period);

(iii) the aggregate Fair Market Value of all outstanding Investments owned by such Unrestricted Subsidiary will be deemed to be an Investment made as of the time of the designation and any such designation will only be permitted if the Investment would be permitted at that time in compliance with Section 5.10;

(iv) all Liens upon property and assets of such Unrestricted Subsidiary existing at the time of such designation would be permitted under Section 5.8; and

(v) if required pursuant to Section 12.1, such Unrestricted Subsidiary becomes a Guarantor pursuant to such covenant within 10 Business Days of the date on which it is so designated.

5.20 Business Activities

The Corporation will not, and will not permit any Restricted Subsidiary to, engage in any business other than the Energy Business, except to the extent as would not be material to the Corporation and the Restricted Subsidiaries taken as a whole.

77

The Corporation confirms that it has either (i) a class of securities registered pursuant to section 12 of the US Securities Exchange Act of 1934, as amended; or (ii) a reporting obligation pursuant to section 15(d) of the US Securities Exchange Act of 1934, as amended, and has provided the Trustee with an Officers’ Certificate (certifying such reporting obligation and other information as requested by the Trustee). The Corporation covenants that in the event that any such registration or reporting obligation shall be terminated by the Corporation in accordance with the US Securities Exchange Act of 1934 as amended, the Corporation shall promptly notify the Trustee of such termination and such other information as the Trustee may require at the time. The Corporation acknowledges that the Trustee is relying upon the foregoing representation and covenants in order to meet certain United States Securities and Exchange Commission (“SEC”) obligations with respect to those clients who are filing with the SEC.

Article 6
DEFAULT AND ENFORCEMENT

6.1 Events of Default and Remedies

Each of the following is an “Event of Default”:

(a) default for 30 days in the payment when due of interest on the Notes;

(b) default in payment when due of the principal of, or premium, if any, on the Notes;

(c) failure by the Corporation or any of its Restricted Subsidiaries to comply with Sections 5.14 or 5.15 or Article 9;

(d) failure by the Corporation or any of its Restricted Subsidiaries to comply with any of the other agreements in this Indenture for 60 days after written notice has been given to the Corporation by the Trustee or to the Corporation and the Trustee by Holders of at least 25% of the outstanding principal amount of the Notes;

(e) default under any other mortgage, Indenture or instrument under which there may be issued or by which there may be secured or evidenced any Indebtedness for borrowed money (except in respect of Non-Recourse Equity Pledge Debt) by the Corporation or any of its Restricted Subsidiaries (or the payment of which is guaranteed by the Corporation or any of its Restricted Subsidiaries) whether such Indebtedness or Guarantee now exists, or is created after the date of this Indenture, if that default:

(i) is caused by a failure to pay principal of, or interest or premium, if any, on such Indebtedness prior to the expiration of the applicable grace or cure period provided in such Indebtedness on the date of such default (a “Payment Default”); or

(ii) results in the acceleration of such Indebtedness prior to its Stated Maturity,

(f) and, in each case, the principal amount of any such Indebtedness, together with the principal amount of any other such Indebtedness under which there has been a Payment Default, which remains outstanding or the maturity of which has been so accelerated, aggregates an amount greater than $30,000,000, provided that if any such Payment Default is cured or waived or any such acceleration is rescinded, or such Indebtedness is repaid, within a period of 30 days from the continuation of such Payment Default beyond the applicable grace or cure period or the occurrence of such acceleration, as the case may be, such Event of Default under this Indenture and any consequential acceleration of the Notes shall be automatically rescinded, so long as such rescission does not conflict with any judgment or decree of a court of competent jurisdiction;

78

(g) failure by the Corporation or any Guarantor to pay final judgments aggregating in excess of an amount greater than $30,000,000 in cash (net of amounts covered by insurance or bonded), which judgments are not paid, discharged or stayed for a period of 60 days after such judgments becomes final and non-appealable or, in the event such judgments have been bonded to the extent required pending appeal, after the date such judgments become non-appealable;

(h) except as permitted by this Indenture, the Subsidiary Guarantee of any Guarantor shall be held in any judicial proceeding to be unenforceable or invalid or shall cease for any reason to be in full force and effect and such failure shall not be cured within 10 days, or any Guarantor or any Persons acting on behalf of such Guarantor shall deny or disaffirm its obligations under its Subsidiary Guarantee (other than by reason of release of any such Guarantor from its Subsidiary Guarantee in accordance with this Indenture); and

(i) the Corporation or any of its Subsidiaries pursuant to or within the meaning of any Bankruptcy Law:

(i) commences a voluntary case or proceeding;

(ii) applies for or consents to the entry of an order for relief against it in an involuntary case or proceeding;

(iii) applies for or consents to the appointment of a Custodian of it or for all or substantially all of its assets; or

(iv) makes a general assignment for the benefit of its creditors; or

(j) a court of competent jurisdiction enters an order or decree under any Bankruptcy Law that:

(i) is for relief against the Corporation or any of its Subsidiaries as debtor in an involuntary case or proceeding;

(ii) appoints a Custodian of the Corporation or any of its Subsidiaries or a Custodian for all or substantially all of the assets of the Corporation or any of its Subsidiaries; or

(iii) orders the liquidation of the Corporation or any of its Subsidiaries,

and the order or decree remains unstayed and in effect for 60 consecutive days and, in the case of the insolvency of a Restricted Subsidiary, such Restricted Subsidiary remains a Restricted Subsidiary on such 60th day.

6.2 Acceleration of Maturity; Rescission, Annulment and Waiver

(a) In the case of an Event of Default under Sections 6.1(i) or 6.1(j) with respect to the Corporation or any of its Restricted Subsidiaries, all outstanding Notes will become immediately due and payable without further action or notice. If any other Event of Default occurs and is continuing, the Trustee or the Holders of at least 25% in principal amount of the then outstanding Notes may declare (an “acceleration declaration”) all the Notes to be due and payable immediately by notice in writing to the Corporation and (if given by the Holders) to the Trustee specifying the Event of Default. Upon such acceleration declaration, the aggregate principal amount of and accrued and unpaid interest on the outstanding Notes shall become immediately due and payable; provided, however, that after such acceleration, the Holders of a majority in aggregate principal amount of the Notes then outstanding may rescind and annul such acceleration if: (a) all existing Events

79

of Defaults, other than the non-payment of the principal of, interest and premium (if any) on the Notes that have become due solely by the acceleration declaration, have been cured or waived; and (b) the rescission would not conflict with any judgment or decree of a court of competent jurisdiction.

(b) The Trustee may withhold from Holders of the Notes notice of any continuing Default or Event of Default if it determines that withholding notice is in their interest, except a Default or Event of Default relating to the payment of principal or interest.

(c) The Holders of a majority in aggregate principal amount of the Notes then outstanding by notice to the Trustee may on behalf of the Holders of all of the Notes waive any existing Default or Event of Default and its consequences under this Indenture except a continuing Default or Event of Default in the payment of interest or premium (if any) on, or the principal of, the Notes.

6.3 Collection of Indebtedness and Suits for Enforcement by Trustee

(a) The Corporation covenants that if:

(i) Default is made in the payment of any instalment of interest on any Note when such interest becomes due and payable and such default continues for a period of 30 days; or

(ii) Default is made in the payment of the principal of or premium (if any) on any Note at Maturity thereof and such default continues for a period of three Business Days,

the Corporation will, upon demand of the Trustee, acting on the instructions of the Majority Holders, pay to the Trustee for the benefit of the Holders, the whole amount then due and payable on such Notes for principal and premium (if any) and interest, and interest on any overdue principal and premium (if any) and, to the extent that payment of such interest shall be legally enforceable, upon any overdue instalment of interest, at the rate borne by the Notes, and, in addition thereto, such further amount as shall be sufficient to cover the costs and expenses of collection, including the reasonable compensation, expenses, disbursements and advances of the Trustee, its agents and Counsel.

(b) If the Corporation fails to pay such amounts forthwith upon such demand, the Trustee, in its own name as trustee of an express trust, may institute a judicial proceeding for the collection of the sums so due and unpaid, may prosecute such proceeding to judgment or final decree and may enforce the same against the Corporation or any other obligor (including the Guarantors, if any) upon the Notes and collect the moneys adjudged or decreed to be payable in the manner provided by law out of the property of the Corporation or any other obligor upon the Notes, wherever situated.

(c) If an Event of Default occurs and is continuing, the Trustee may, acting on the instructions of the Majority Holders, proceed to protect and enforce its rights and the rights of the Holders by such appropriate judicial proceedings most effective to protect and enforce any such rights, whether for the specific enforcement of any covenant or agreement in this Indenture or in aid of the exercise of any power granted herein, or to enforce any other proper remedy.

6.4 Trustee May File Proofs of Claim

(a) In case of any pending receivership, insolvency, liquidation, bankruptcy, reorganization, arrangement, adjustment, composition or other judicial proceeding relative to the Corporation and its debts or any other obligor upon the Notes (including the Guarantors),

80

and their debts or the properties or assets of the Corporation or of such other obligor or their creditors, the Trustee, acting on the instructions of the Majority Holders (irrespective of whether the principal of the Notes shall then be due and payable as therein expressed or by declaration or otherwise and irrespective of whether the Trustee shall have made any demand on the Corporation for the payment of overdue principal and premium (if any) or interest), shall be entitled and empowered, by intervention in such proceeding or otherwise:

(i) to file and prove a claim for the whole amount of principal and premium (if any) and interest owing and unpaid in respect of the Notes and to file such other papers or documents as may be necessary or advisable in order to have the claims of the Trustee (including any claim for the reasonable compensation, expenses, disbursements and advances of the Trustee, its agents and Counsel) and of the Holders allowed in such judicial proceeding; and

(ii) to collect and receive any moneys or other securities or property payable or deliverable upon the conversion or exchange of such securities or upon any such claims and to distribute the same,

and any Custodian, receiver, assignee, trustee, liquidator, sequestrator or similar official in any such judicial proceeding is hereby authorized by each Holder to make such payments to the Trustee and, in the event that the Trustee shall consent to the making of such payments directly to the Holders, to pay the Trustee any amount due to it for the reasonable compensation, expenses, disbursements and advances of the Trustee, its agents and Counsel, and any other amounts due to the Trustee hereunder.

(b) Nothing herein contained shall be deemed to authorize the Trustee to authorize or consent to or accept or adopt on behalf of any Holder any plan of reorganization, arrangement, adjustment or composition affecting the Notes or the rights of any Holder thereof, or to authorize the Trustee to vote in respect of the claim of any Holder in any such proceeding.

6.5 Trustee May Enforce Claims Without Possession of Notes

All rights of action and claims under this Indenture or the Notes may be prosecuted and enforced by the Trustee without the possession of any of the Notes or the production thereof in any proceeding relating thereto, and any such proceeding instituted by the Trustee shall be brought in its own name as trustee of an express trust, and any recovery of judgment shall, after provision for the payment of the reasonable compensation, expenses, disbursements and advances of the Trustee, its agents and Counsel, be for the rateable benefit of the Holders of the Notes in respect of which such judgment has been recovered.

6.6 Application of Monies by Trustee

Except as herein otherwise expressly provided, any money collected by the Trustee pursuant to this Article 6 shall be applied in the following order, at the date or dates fixed by the Trustee and, in case of the distribution of such money on account of principal, premium (if any) or interest, upon presentation of the Notes and the notation thereon (or in the case of uncertificated Notes, in accordance with the Trustee’s Internal Procedures) of the payment if only partially paid and upon surrender thereof if fully paid:

(a) first, in payment or in reimbursement to the Trustee of its reasonable compensation, fees, costs, charges, expenses, borrowings, advances or other monies furnished or provided by the Trustee in or about the execution of its trusts under, or otherwise in relation to, this Indenture, including indemnities in favour of the Trustee under this Indenture;

(b) second, but subject as hereinafter in this Section 6.6 provided, in payment, rateably and proportionately to the Holders, of the principal of, premium (if any) on, accrued and unpaid

81

interest on and interest on amounts in default on the Notes which shall then be outstanding in the priority of principal first and then premium and then accrued and unpaid interest and then interest on amounts in default unless otherwise directed by the Majority Holders and in that case in such order or priority as between principal, premium and interest as may be directed by such resolution; and

(c) third, in payment of the surplus, if any, of such monies to the Corporation or its assigns and/or the Guarantors, as the case may be;

provided, however, that no payment shall be made pursuant to Section 6.6(b) above in respect of the principal, premium or interest on any Notes held, directly or indirectly, by or for the benefit of the Corporation or any Subsidiary of the Corporation (other than any Notes pledged for value and in good faith to a Person other than the Corporation or any Subsidiary of the Corporation but only to the extent of such Person’s interest therein), except subject to the prior payment in full of the principal, premium (if any) and interest on all Notes which are not so held.

6.7 No Suits by Holders

Except to enforce payment of the principal of, and premium (if any) or interest on any Note on or after the Stated Maturity of such payment (after giving effect to the grace periods specified in Section 6.1(a)), a Holder will not have any right to institute any proceeding with respect to this Indenture, or for the appointment of a liquidator, trustee or receiver or for a receiving order under any Bankruptcy Laws or to have the Corporation or any Guarantor wound up or to file or prove a claim in any liquidation or bankruptcy proceeding or for any other remedy hereunder, unless, unless:

(a) the Holders of at least 25% in aggregate principal amount of outstanding Notes provide written notice to the Trustee of a continuing Event of Default and make a written request to the Trustee to pursue such remedy;

(b) the Trustee has been offered indemnity satisfactory to it in its reasonable judgment;

(c) the Trustee shall have failed to act for a period of 60 days after having received (a) and (b) above; and

(d) during such 60 day period, the Trustee has not received from the Holders of a majority in aggregate principal amount of the Notes then outstanding a direction inconsistent with such request.

it being understood and intended that no one or more Holders shall have any right in any manner whatever by virtue of, or by availing of, any provision of this Indenture to affect, disturb or prejudice the rights of any other Holders, or to obtain or to seek to obtain priority or preference over any other Holders or to enforce any right under this Indenture, except in the manner herein provided and for the equal and rateable benefit of all the Holders.

6.8 Unconditional Right of Holders to Receive Principal, Premium and Interest

Notwithstanding any other provision in this Indenture, a Holder shall have the right, which is absolute and unconditional, to receive payment, as provided herein, of the principal of, premium (if any) and interest on the Notes held by such Holder on the applicable Maturity and to institute suit for the enforcement of any such payment, and such rights shall not be impaired without the consent of such Holder.

6.9 Restoration of Rights and Remedies

If the Trustee, acting on the instructions of the Majority Holders, or any Holder has instituted any proceeding to enforce any right or remedy under this Indenture and such proceeding has been discontinued

82

or abandoned for any reason, or has been determined adversely to the Trustee or to such Holder, then and in every such case, subject to any determination in such proceeding, the Corporation, the Guarantors (if any), the Trustee and the Holders shall be restored severally and respectively to their former positions hereunder and thereafter all rights and remedies of the Trustee and the Holders shall continue as though no such proceeding had been instituted.

6.10 Rights and Remedies Cumulative

Except as otherwise expressly provided herein, no right or remedy herein conferred upon or reserved to the Trustee or to the Holders is intended to be exclusive of any other right or remedy, and every right and remedy shall, to the extent permitted by law, be cumulative and in addition to every other right and remedy given hereunder or now or hereafter existing at law or in equity or otherwise. The assertion or employment of any right or remedy hereunder, or otherwise, shall not prevent the concurrent assertion or employment of any other appropriate right or remedy.

6.11 Delay or Omission Not Waiver

No delay or omission of the Trustee or of any Holder to exercise any right or remedy accruing upon any Event of Default shall impair any such right or remedy or constitute a waiver of any such Event of Default or an acquiescence therein. Every right and remedy given by this Article 6 or by law to the Trustee or to the Holders may be exercised from time to time, and as often as may be deemed expedient, by the Trustee or by the Holders, as the case may be.

6.12 Control by Holders

Subject to Section 10.3, the Holders of a majority in principal amount of the then outstanding Notes shall have the right to direct the time, method and place of conducting any proceeding for exercising any remedy available to the Trustee, or exercising any trust or power conferred on the Trustee, provided that:

(a) such direction shall not be in conflict with any rule of law or with this Indenture;

(b) the Trustee may take any other action deemed proper by the Trustee which is not inconsistent with such direction; and

(c) the Trustee shall have the right to not take any action which might involve it in personal liability or be unjustly prejudicial to the Holders not consenting.

6.13 Notice of Event of Default

If an Event of Default shall occur and be continuing the Trustee shall, within 30 days after it receives written notice of the occurrence of such Event of Default, give notice of such Event of Default to the Holders in the manner provided in Section 13.2; provided that, notwithstanding the foregoing, unless the Trustee shall have been requested to do so by the Holders of at least 25% of the principal amount of the Notes then outstanding, the Trustee shall not be required to give such notice to the Holders if the Trustee in good faith shall have determined that the withholding of such notice is in the best interests of the Holders and shall have so advised the Corporation in writing. Notwithstanding the foregoing, notice relating to a Default or Event of Default relating to the payment of principal or interest shall not in any circumstances be withheld.

6.14 Waiver of Stay or Extension Laws

The Corporation covenants (to the extent that it may lawfully do so) that it will not at any time insist upon, or plead, or in any manner whatsoever claim or take the benefit or advantage of, any stay or extension law wherever enacted, now or at any time hereafter in force, which may affect the covenants or the performance of this Indenture; and the Corporation (to the extent that it may lawfully do so) hereby expressly waives all benefit or advantage of any such law and covenants that it will not hinder, delay or impede the

83

execution of any power herein granted to the Trustee, but will suffer and permit the execution of every such power as though no such law had been enacted.

6.15 Undertaking for Costs

All parties to this Indenture agree, and each Holder of any Note by such Holder’s acceptance thereof shall be deemed to have agreed, that any court may in its discretion require, in any suit for the enforcement of any right or remedy under this Indenture, or in any suit against the Trustee for any action taken, suffered or omitted by it as Trustee, the filing by any party litigant in such suit of an undertaking to pay the costs of such suit, and that such court may in its discretion assess reasonable costs, including reasonable attorney’s fees, against any party litigant in such suit, having due regard to the merits and good faith of the claims or defenses made by such party litigant.

6.16 Judgment Against the Corporation

The Corporation covenants and agrees with the Trustee that, in case of any judicial or other proceedings to enforce the rights of the Holders, judgment may be rendered against it in favour of the Holders or in favour of the Trustee, as trustee for the Holders, for any amount which may remain due in respect of the Notes and premium (if any) and the interest thereon and any other monies owing hereunder.

6.17 No Personal Liability of Directors, Officers, Employees and Shareholders

No past, present or future director, officer, employee, incorporator or shareholder of the Corporation or any Guarantor, as such, will have any liability for any obligations of the Corporation or any Guarantor under the Notes, this Indenture or the Subsidiary Guarantees or for any claim based on, in respect of, or by reason of, such obligations or their creation. Each Holder by accepting a Note waives and releases all such liability. The waiver and release are part of the consideration for issuance of the Notes.

6.18 Trustee May Demand Production of Notes

The Trustee shall have the right to demand production of certificated Notes in respect of which any payment of principal, premium (if any) or interest required by this Article 6 is made and may cause to be endorsed on the same a memorandum of the amount so paid and the date of payment, but the Trustee may, in its discretion, dispense with such production and endorsement.

Article 7
DISCHARGE AND DEFEASANCE

7.1 Satisfaction and Discharge

This Indenture will cease to be of further effect as to all Notes issued thereunder, when:

(a) either:

(i) all Notes that have been authenticated, except lost, stolen or destroyed Notes that have been replaced or paid and Notes for whose payment money has been deposited in trust and thereafter repaid to the Corporation, have been delivered to the Trustee for cancellation; or

(ii) all Notes that have not been delivered to the Trustee for cancellation have become due and payable by reason of the mailing of an unconditional notice of redemption or otherwise or will become due and payable within one year and the Corporation has irrevocably deposited or caused to be deposited with the Trustee as trust funds in trust solely for the benefit of the Holders, cash in Canadian dollars, Canadian Government Obligations, or a combination of cash in Canadian dollars and

84

Canadian Government Obligations, in amounts as will be sufficient to pay and discharge the principal, premium, if any, and accrued interest to the date of maturity or redemption;

(b) no Default or Event of Default has occurred and is continuing on the date of the deposit or will occur as a result of the deposit other than a Default or Event of Default resulting from the borrowing of funds to be applied to such deposit and the deposit will not result in a breach or violation of, or constitute a default under, any other instrument to which the Corporation or any of its Restricted Subsidiaries is a party or by which the Corporation or any of its Restricted Subsidiaries is bound;

(c) the Corporation or any Guarantor has paid or caused to be paid all sums payable by the Corporation under this Indenture; and

(d) the Corporation has delivered irrevocable instructions to the Trustee under this Indenture to apply the deposited money toward the payment of the Notes at maturity or the redemption date, as the case may be.

Notwithstanding the satisfaction and discharge of this Indenture, if money has been deposited with the Trustee pursuant to Section 7.1(a)(ii), the provisions of Sections 7.7 and 7.8 will survive.

7.2 Option to Effect Legal Defeasance or Covenant Defeasance

The Corporation may, at the option of the Board of Directors of the Corporation evidenced by a Board Resolution, at any time, elect to have either Section 7.3 or 7.4 applied to all outstanding Notes and all obligations of any Guarantors upon compliance with the conditions set forth in this Article 7.

7.3 Legal Defeasance and Discharge

Upon the Corporation’s exercise under Section 7.2 of the option applicable to this Section 7.3 in respect of the Notes, subject to the satisfaction of the conditions set forth in Section 7.5, be deemed to have been discharged from their Obligations under this Indenture and Subsidiary Guarantees, other than the provisions contemplated to survive as set forth below, with respect to all outstanding Notes on the date the conditions set forth below are satisfied (hereinafter, “Legal Defeasance”). For this purpose, Legal Defeasance means that the Corporation and the Guarantors shall be deemed to have paid and discharged the entire obligations represented by the Notes and the Subsidiary Guarantees, and this Indenture shall cease to be of further effect as to all outstanding Notes and Subsidiary Guarantees, which shall thereafter be deemed to be “outstanding” only for the purposes of Sections 7.6 and 7.8 and the other Sections of this Indenture referred to in Section 7.3(a) through to Section 7.3(d), and to have satisfied all their other obligations under such Notes and, to the extent applicable to such Notes, this Indenture and the Subsidiary Guarantees (and the Trustee, on demand of and at the expense of the Corporation, shall execute proper instruments acknowledging the same), except for the following provisions which shall survive until otherwise terminated or discharged hereunder:

(a) rights of Holders of outstanding Notes to receive payments in respect of the principal of and premium, if any, and interest on such Notes when such payments are due from the trust funds referred to in Section 7.6;

(b) the Corporation’s obligations under Sections 2.10, 2.11 and 2.14;

(c) the rights, powers, trust, duties, and immunities of the Trustee, and the obligations of the Corporation and the Guarantors in connection therewith under Article 10; and

(d) this Section 7.3.

85

Subject to compliance with Section 7.2, the Corporation may exercise its option under this Section 7.3 notwithstanding the prior exercise of its option under Section 7.4.

7.4 Covenant Defeasance

Upon the Corporation’s exercise under Section 7.2 of the option applicable to this Section 7.4, the Corporation and each of the Guarantors shall, subject to the satisfaction of the conditions set forth in Section 7.5, be released from each of their obligations under the covenants contained in Sections 5.6, 5.7, 5.8, 5.10, 5.11(a), 5.12, 5.13, 5.14, 5.15 and 9.1(a)(iv) (collectively, the “Defeased Covenants”) with respect to the outstanding Notes on and after the date the conditions set forth in Section 7.5 are satisfied (hereinafter, “Covenant Defeasance”), and such Notes shall thereafter be deemed not “outstanding” for the purposes of any direction, waiver, consent or declaration or act of Holders thereof (and the consequences of any thereof) in connection with the Defeased Covenants, but shall continue to be deemed “outstanding” for all other purposes hereunder (it being understood that such Notes shall not be deemed outstanding for accounting purposes). For this purpose, Covenant Defeasance means that, with respect to the outstanding Notes, the Corporation and the Guarantors may omit to comply with and shall have no liability in respect of any term, condition or limitation set forth in any Defeased Covenant, whether directly or indirectly, by reason of any reference elsewhere herein to any such covenant or by reason of any reference in any such covenant to any other provision herein or in any other document and such omission to comply shall not constitute a Default or an Event of Default hereunder, but, except as specified above, the remainder of this Indenture, such Notes and the obligations of the Guarantors under their respective Subsidiary Guarantees shall be unaffected thereby. In addition, upon the Corporation’s exercise under Section 7.2 of the option applicable to this Section 7.4, and subject to the satisfaction of the conditions set forth in Section 7.5, payment of the Notes may not be accelerated because of an Event of Default specified in Sections 6.1(c), 6.1(d), 6.1(e), 6.1(g) and 6.1(h).

7.5 Conditions to Legal or Covenant Defeasance

(a) In order to exercise either Legal Defeasance under Section 7.3 or Covenant Defeasance under Section 7.4:

(i) the Corporation must irrevocably deposit with the Trustee, as trust funds, in trust solely for the benefit of the Holders, cash in Canadian dollars, non-callable Canadian Government Obligations or a combination thereof, in such amounts as will be sufficient (without consideration of any reinvestment of interest) in the opinion of a nationally recognized investment bank, appraisal firm or firm of independent public accountants selected by the Corporation and delivered to the Trustee, to pay the principal of and interest on the outstanding Notes on the stated date for payment thereof or on the applicable redemption date, as the case may be;

(ii) the Corporation shall have delivered to the Trustee an opinion of counsel acceptable to the Trustee, in its reasonable judgment, or an advance tax ruling from the Canada Revenue Agency (or successor agency) to the effect that the beneficial owners of outstanding Notes will not recognize income, gain, or loss for Canadian federal, provincial or territorial income tax purposes as a result of such Legal Defeasance or Covenant Defeasance, as applicable, and will be subject to Canadian federal, provincial or territorial income tax on the same amounts, in the same manner, and at the same times as would have been the case if such Legal Defeasance or Covenant Defeasance, as applicable, had not occurred;

(iii) no Default shall have occurred and be continuing, either (a) on the date of such deposit (other than a Default resulting from the borrowing of funds to be applied to such deposit and the grant of any Lien securing such borrowings) or (b) insofar as Defaults from bankruptcy or insolvency events are concerned, at any time in the period ending on the 91st day after the date of deposit;

86

(iv) the Legal Defeasance or Covenant Defeasance shall not result in a breach or violation of, or constitute a default under any other material agreement or instrument to which the Corporation or any of its Subsidiaries is a party or by which the Corporation or any of its Subsidiaries is bound;

(v) the Corporation shall have delivered to the Trustee an Officer’s Certificate stating that, at the time of the deposit, the Corporation was not an “insolvent person” (as defined in the Bankruptcy and Insolvency Act (Canada)) and that the deposit was not made by it with the intent of preferring the Holders over any other of its creditors or with the intent of defeating, hindering, delaying or defrauding any other of its creditors or others;

(vi) if the Notes are to be redeemed prior to their Stated Maturity, the Corporation must deliver to the Trustee irrevocable instructions to redeem all of the Notes on the specified redemption date; and

(vii) the Corporation shall have delivered to the Trustee an Officer’s Certificate stating that the conditions precedent provided for in clauses (i) through (vi) have been complied with.

(b) If the funds deposited with the Trustee to effect Covenant Defeasance are insufficient to pay the principal of and interest on the Notes when due, then the Corporation’s obligations and the obligations of the Guarantors under this Indenture and the respective Subsidiary Guarantees will be revived and no such defeasance will be deemed to have occurred.

7.6 Application of Trust Funds

(a) Subject to Section 7.7, any funds deposited with the Trustee pursuant to Section 7.1 or 7.5 in respect of Notes shall be (i) denominated in the currency or denomination of the Notes in respect of which such deposit is made, (ii) irrevocable, subject to certain exceptions, and (iii) made under the terms of an escrow and/or trust agreement in form and substance satisfactory to the Trustee and which provides for the due and punctual payment of the principal of, premium, if any, and interest (having regard to the then applicable interest rate) on the Notes being satisfied.

(b) If the Trustee or Paying Agent is unable to apply any funds in accordance with Section 7.1 or 7.5 by reason of any legal proceeding or any order or judgment of any court or governmental authority enjoining, restraining or otherwise prohibiting such application, the Corporation’s and the Guarantors’ obligations under this Indenture and the affected Notes shall be revived and reinstated as though no funds had been deposited pursuant to Section 7.1 or 7.5, as applicable, until such time as the Trustee is permitted to apply all such funds in accordance with such provisions; provided that if the Corporation or any Guarantor has made any payment in respect of principal of, premium (if any) or interest on any Notes or, as applicable, other amounts because of the reinstatement of its obligations, the Corporation and such Guarantor, as applicable, shall be subrogated to the rights of the Holders of such Notes to receive such payment from the funds held by the Trustee.

7.7 Repayment to the Corporation

Notwithstanding anything in this Article 7 to the contrary, the Trustee will deliver or pay to the Corporation from time to time upon the request of the Corporation any funds held by it as provided in Section 7.1 or 7.5 which, in the opinion of a nationally recognized firm of independent public accountants expressed in a written certification thereof delivered to the Trustee, are in excess of the amount thereof that would then be required to be deposited to fully satisfy the obligations of the Corporation under Section 7.1(a)(i) or to effect an equivalent Legal Defeasance or Covenant Defeasance, as the case may be.

87

7.8 Continuance of Rights, Duties and Obligations

Where trust funds or trust property have been deposited pursuant to Section 7.1 or 7.5, the Holders and the Corporation shall continue to have and be subject to their respective rights, duties and obligations under Article 7 and Article 4. In the event that after the deposit of trust funds or trust property pursuant to Section 7.1 or 7.5, the Corporation is required to make an offer to purchase any outstanding Notes pursuant to the terms hereof, the Corporation shall be entitled to use any trust funds or trust property deposited with the Trustee pursuant to Section 7.1 or 7.5 for the purpose of paying to any Holders of such Notes who have accepted any such offer of the total offer price payable in respect of an offer relating to any such Notes. Upon receipt of a Corporation Order, the Trustee shall be entitled to pay to such Holder from such trust funds or trust property deposited with the Trustee pursuant to Section 7.1 or 7.5 in respect of such Notes which is applicable to the Notes held by such Holders who have accepted any such offer of the Corporation (which amount shall be based on the applicable principal amount of the Notes held by accepting offerees in relation to the aggregate outstanding principal amount of all the Notes).

Article 8
MEETINGS OF HOLDERS

8.1 Purpose, Effect and Convention of Meetings

(a) Wherever in this Indenture a consent, waiver, notice, authorization or resolution of the Holders (or any of them) is required, a meeting may be convened in accordance with this Article 8 to consider and resolve whether such consent, waiver, notice, authorization or resolution should be approved by such Holders. A resolution passed by the affirmative votes of the Holders of at least a majority of the outstanding principal amount of the Notes represented and voting on a poll at a meeting of Holders duly convened for the purpose and held in accordance with the provisions of this Indenture shall constitute conclusively such consent, waiver, notice, authorization or resolution; provided that with respect to any of the matters in Section 11.2, such resolution must be passed by the affirmative vote of each affected Holder.

(b) At any time and from time to time, the Trustee may and, on receipt of a Corporation Order or a Holders’ Request and upon being indemnified and funded for the costs thereof to the reasonable satisfaction of the Trustee by the Corporation or the Holders signing such Holders’ Request, will convene a meeting of all Holders.

(c) If the Trustee fails to convene a meeting after being duly requested as aforesaid (and indemnified and funded as aforesaid), the Corporation or such Holders may themselves convene such meeting and the notice calling such meeting may be signed by such Person as the Corporation or those Holders designate, as applicable. Every such meeting will be held in Calgary, Alberta or by electronic means such that the meeting is held entirely or partially virtually or at such other place as the Trustee may in any case determine or approve.

8.2 Notice of Meetings

Not more than 60 days’ nor less than 21 days’ notice of any meeting of the Holders shall be given to the Holders, in the manner provided in Section 13.2 and a copy of such notice shall be provided to the Trustee, unless the meeting has been called by it, and to the Corporation, unless such meeting has been called by it. Such notice shall state the time when and the place where the meeting is to be held and shall state briefly the general nature of the business to be transacted thereat and it shall not be necessary for any such notice to set out the terms of any resolution to be proposed or any of the provisions of this Article 8. The accidental omission to give notice of a meeting to any Holder shall not invalidate any resolution passed at any such meeting. A Holder may waive notice of a meeting either before or after the meeting.

88

8.3 Chair

Some individual, who need not be a Holder, nominated in writing by the Trustee shall be chair of the meeting and if no individual is so nominated, or if the individual so nominated is not present within 15 minutes from the time fixed for the holding of the meeting, the majority of the Holders present in person or by proxy shall choose some individual present to be chair.

8.4 Quorum

Subject to this Indenture, at any meeting of the Holders a quorum shall consist of Holders present in person or by proxy and representing at least 25% of the principal amount of the then outstanding Notes. If a quorum of the Holders shall not be present within 30 minutes from the time fixed for holding any meeting, the meeting, if convened by the Holders or pursuant to a Holders’ Request, shall be dissolved, but in any other case the meeting shall be adjourned to the same day in the next week (unless such day is not a Business Day in which case it shall be adjourned to the next following Business Day thereafter) at the same time and place and no notice shall be required to be given in respect of such adjourned meeting. At the adjourned meeting, the Holders present in person or by proxy shall constitute a quorum and may transact the business for which the meeting was originally convened notwithstanding that they may not represent 25% of the principal amount of the then outstanding Notes. Any business may be brought before or dealt with at an adjourned meeting which might have been brought before or dealt with at the original meeting in accordance with the notice calling the same. No business shall be transacted at any meeting unless the required quorum be present at the commencement of business.

8.5 Power to Adjourn

The chair of any meeting at which the requisite quorum of the Holders is present may, with the consent of the majority of the Holders (having regard to the principal amount of the then outstanding Notes) represented thereat, adjourn any such meeting and no notice of such adjournment need be given except such notice, if any, as the meeting may prescribe.

8.6 Voting

On a poll each Holder present in person or represented by a duly appointed proxy shall be entitled to one vote in respect of each $1,000 principal amount of the Notes of which it is the Holder. A proxyholder need not be a Holder. In the case of joint registered Holders of a Note, any one of them present in person or by proxy at the meeting may vote in the absence of the other or others, but in case more than one of them is present in person or by proxy, they shall vote together in respect of the Notes of which they are joint Holders.

8.7 Poll

A poll will be taken on every resolution submitted for approval at a meeting of Holders, in such manner as the chair directs, and the results of such polls shall be binding on all Holders.

8.8 Proxies

A Holder may vote at any meeting of Holders by an authorized representative. The Corporation (in case it convenes the meeting) or the Trustee (in any other case) for the purpose of enabling the Holders to be present and vote at any meeting without producing their Notes, and for enabling them to be present and vote at any such meeting by proxy and for depositing instruments appointing such proxies at some place other than the place where the meeting is to be held, may from time to time make and vary such regulations as it shall think fit providing for and governing any or all of the following matters:

89

(a) the form of the instrument appointing a proxy, which shall be in writing, and the manner in which the same shall be executed and the production of the authority of any individual signing on behalf of a Holder;

(b) the deposit of instruments appointing proxies at such place as the Trustee, the Corporation or the Holder convening the meeting, as the case may be, may, in the notice convening the meeting, direct and the time, if any, before the holding of the meeting or any adjournment thereof by which the same must be deposited; and

(c) the deposit of instruments appointing proxies at some approved place or places other than the place at which the meeting is to be held and enabling particulars of such instruments appointing proxies to be mailed, faxed or sent by other electronic means before the meeting to the Corporation or to the Trustee at the place where the same is to be held and for the voting of proxies so deposited as though the instruments themselves were produced at the meeting.

Any regulations so made shall be binding and effective and the votes given in accordance therewith shall be valid and shall be counted. Save as such regulations may provide, the only Persons who shall be recognized at any meeting as the Holders of any Notes, or as entitled to vote or be present at the meeting in respect thereof, shall be Holders and Persons whom Holders have by instrument in writing duly appointed as their proxies.

8.9 Persons Entitled to Attend Meetings

The Corporation and the Trustee, by their respective directors, officers and employees and the respective legal advisors of the Corporation, the Trustee or any Holder may attend any meeting of the Holders, but shall have no vote as such.

8.10 Powers Cumulative

Any one or more of the powers in this Indenture stated to be exercisable by the Holders by resolution or otherwise may be exercised from time to time and the exercise of any one or more of such powers from time to time shall not be deemed to exhaust the rights of the Holders to exercise the same or any other such power or powers thereafter from time to time. No powers exercisable by resolution will derogate in any way from the rights of the Corporation pursuant to this Indenture.

8.11 Minutes

Minutes of all resolutions and proceedings at every meeting as aforesaid shall be made and duly entered in books to be from time to time provided for that purpose by the Corporation at the expense of the Corporation, and any such minutes as aforesaid, if signed by the chair of the meeting at which such resolutions were passed or proceedings had, or by the chair of the next succeeding meeting of the Holders, shall be prima facie evidence of the matters therein stated and, until the contrary is proved, every such meeting, in respect of the proceedings of which minutes shall have been made, shall be deemed to have been duly held and convened, and all resolutions passed thereat or proceedings taken thereat to have been duly passed and taken. Notice of any resolution passed in accordance with this Section 8.11 will be given by the Trustee to the affected Holders within 30 days of the date on which such resolution was passed.

8.12 Instruments in Writing

Any consent, waiver, notice, authorization or resolution of the Holders which may be given by resolution at a meeting of the Holders pursuant to this Article 8 may also be given by the Holders of a majority of the aggregate principal amount of the Notes then outstanding by a signed instrument in one or more counterparts or in accordance with the procedures of the Depository; provided that with respect to

90

any of the matters in Section 11.2, such consent, waiver, notice, authorization or resolution must be given by each Holder affected.

8.13 Binding Effect of Resolutions

Every resolution passed in accordance with the provisions of this Article 8 at a meeting of Holders shall be binding upon all the Holders, and every instrument in writing signed by Holders pursuant to Section 8.12 and every consent, waiver, notice, authorization or resolution otherwise provided in accordance with the procedures of the Depository pursuant to Section 8.12 shall be binding upon all the Holders, and each and every Holder and the Trustee (subject to the provisions for their indemnity herein contained) shall, subject to applicable law, be bound to give effect accordingly to every such resolution, instrument in writing or consent, waiver, notice, authorization or resolution provided in accordance with the procedures of the Depository.

8.14 Evidence of Rights of Holders

Any request, direction, notice, consent or other instrument which this Indenture may require or permit to be signed by the Holders may be in any number of concurrent instruments of similar tenor signed by such Holders; provided, however, that the Trustee may require proof of execution in cases where it deems proof desirable and may accept such proof as it shall consider proper.

Article 10
CONCERNING THE TRUSTEE

10.1 No Conflict of Interest

The Trustee represents to the Corporation that at the date of execution and delivery by it of this Indenture to the best of its knowledge and belief there exists no material conflict of interest in the role of the Trustee as a fiduciary hereunder but if, notwithstanding the provisions of this Section 10.1, such a material conflict of interest exists, or hereafter arises, the validity and enforceability of this Indenture and the Notes shall not be affected in any manner whatsoever by reason only that such material conflict of interest exists or arises.

10.2 Replacement of Trustee

(a) Subject to this Article 10, the Trustee may resign its trust and be discharged from all further duties and liabilities hereunder by giving to the Corporation 60 days’ notice in writing or such shorter notice as the Corporation may accept as sufficient. If at any time a material conflict of interest exists in the Trustee’s role as a fiduciary hereunder the Trustee shall, within 90 days after ascertaining that such a material conflict of interest exists, either eliminate such material conflict of interest, apply to the Court of Queen’s Bench (Alberta) for and obtain therefrom permission to continue as Trustee hereunder, or resign in the manner and with the effect specified in this Section 10.2. The validity and enforceability of this Indenture and of the Notes issued hereunder shall not be affected in any manner whatsoever by reason only that such a material conflict of interest exists. In the event of the Trustee resigning or being removed 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 Holders in accordance with the provisions hereof. Failing such appointment by the Corporation, the retiring Trustee or any Holder may apply to a Judge of the Court of Queen’s Bench (Alberta), on such notice as such Judge may direct, and at the Corporation’s expense, 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 Holders and the appointment of such new Trustee shall be effective only upon such new Trustee becoming bound by this Indenture. Any new Trustee appointed under any provision of this Section 10.2 shall be a corporation authorized to carry on the business of a trust company in all of the Provinces of Canada. On any new appointment the new Trustee shall be vested with the same powers, rights, duties and responsibilities as if it had been originally named herein as Trustee. No resignation or removal of the Trustee shall become effective until a successor Trustee is appointed in accordance with this Indenture.

(b) Any entity into which the Trustee may be merged or with or to which it may be consolidated, amalgamated or sold, or any entity resulting from any merger, consolidation, sale or amalgamation to which the Trustee shall be a party or any entity to which the Trustee shall transfer substantially all of its corporate trust business, shall be the successor Trustee under this Indenture without the execution of any instrument or any further act. Nevertheless, upon the written request of the successor Trustee or of the Corporation, the Trustee ceasing to act shall execute and deliver an instrument assigning and transferring to such successor Trustee, upon the trusts herein expressed, all the rights, powers and trusts of the retiring Trustee so ceasing to act, and the retiring Trustee shall, upon payment of its outstanding fees and expenses payable under this Indenture, duly assign, transfer and deliver all property and money held by such Trustee to the successor Trustee so appointed in its place. Should any deed, conveyance or instrument in writing from the Corporation or any Guarantor be required by any new Trustee for more fully and certainly vesting in and confirming to it such estates, properties, rights, powers and trusts, then any and all such deeds, conveyances and instruments in writing shall on request of said new

93

Trustee be made, executed, acknowledged and delivered by the Corporation or such Guarantor, as applicable.

10.3 Duties of Trustee

In the exercise of the rights, duties and obligations prescribed or conferred by the terms of this Indenture, including, without limitation, in case an Event of Default occurs and is continuing, the Trustee shall act honestly and in good faith and exercise that degree of care, diligence and skill of a reasonably prudent person in the conduct of its own affairs. Subject to the foregoing, the Trustee will only be liable for its own wilful misconduct, bad faith or gross negligence (as determined by a final, non-appealable order of a court of competent jurisdiction). The Trustee will not be liable for any act or default on the part of any agent employed by it or a co-Trustee, or for having permitted any agent or co-Trustee to receive and retain any money payable to the Trustee, except as aforesaid. The duties, responsibilities and obligations of the Trustee shall be limited to those expressly set forth herein and no duties, responsibilities or obligations shall be inferred or implied against the Trustee, and the Trustee shall have no obligation to recognize nor have any liability or responsibility arising under any other document or agreement to which the Trustee is not a party, notwithstanding that reference thereto may be made herein. The Trustee will be under no obligation to exercise any of its rights or powers under this Indenture at the request of any Holder, unless such Holder has offered to the Trustee security and indemnity satisfactory to it against any loss, liability or expense. The Trustee shall have the right to perform any of its duties hereunder through agents, attorneys, custodians or nominees and the rights and privileges set out in this Article 10 shall extend to such agents, attorneys, custodians or nominees. The Trustee shall not be liable for the misconduct or negligence of its agents, attorneys, custodians or nominees appointed with due care.

10.4 Reliance Upon Declarations, Opinions, etc.

(a) In the exercise of its rights, duties and obligations hereunder the Trustee may, if acting in good faith and subject to Section 10.8, conclusively rely, as to the truth of the statements and accuracy of the opinions expressed therein, and shall be protected in acting or refraining from acting, upon any resolutions, statutory declarations, statements, opinions, reports, notices, requests, directions, consents, orders, bonds, debentures, notes, other evidence of indebtedness, certificates or other paper or document believed by the Trustee to be genuine and to have been signed or presented by the proper parties, furnished pursuant to any covenant, condition or requirement of this Indenture or required by the Trustee to be furnished to it in the exercise of its rights and duties hereunder, if the Trustee examines such resolutions, statutory declarations, statements, opinions, reports, notices, requests, directions, consents, orders, bonds, debentures, notes, other evidence of indebtedness, certificates or other paper or document and determines that they comply with Section 10.6, if applicable, and with any other applicable requirements of this Indenture. The Trustee may nevertheless, in its discretion, require further proof in cases where it deems further proof desirable. Without restricting the foregoing, the Trustee may request at any time and act and rely (and shall be protected in so acting and relying) on an Opinion of Counsel (whether requested or not) satisfactory to the Trustee notwithstanding that it is delivered by a solicitor or firm which acts as solicitors for the Corporation. The Trustee shall not be bound to make any investigation into the facts or matters stated in any resolutions, statutory declarations, statements, opinions, reports, notices, requests, directions, consents, orders, bonds, debentures, notes, other evidence of indebtedness, certificates or other paper or document, but the Trustee may make such further inquiry or investigation into such facts or matters as it may see fit, and, if the Trustee shall determine to make such further inquiry or investigation, it shall be entitled to examine the books, records and premises of the Corporation, personally or by agent or attorney at the sole cost of the Corporation and shall incur no liability or additional liability of any kind by reason of such inquiry or investigation. For the avoidance of doubt, the Trustee shall not be liable for any action taken by it in good faith and reasonably believed by it to be within the discretion or powers conferred upon it, or taken by it pursuant to any direction or instruction by which it is governed hereunder, or omitted to be taken by it reason of the lack of direction

94

or instruction required hereby for such action. Unless otherwise specifically provided in this Indenture, any demand, request, direction or notice from the Corporation shall be sufficient if signed by an officer of the Corporation.

(b) The Trustee shall have no obligation to ensure or verify compliance with any applicable laws or regulatory requirements on the issue or transfer of any Notes provided such issue or transfer is effected in accordance with the terms of this Indenture. The Trustee shall be entitled to process all transfers and redemptions upon the presumption that such transfer and redemption is permissible pursuant to all applicable laws and regulatory requirements if such transfer and redemption is effected in accordance with the terms of this Indenture. The Trustee shall have no obligation, other than to confer with the Corporation and its Counsel, to ensure that legends appearing on the Notes comply with regulatory requirements or securities laws of any applicable jurisdiction.

10.5 Limitation of Liability

(a) The Trustee may act and rely conclusively on and shall be fully protected in acting and relying upon the instructions of the Majority Holders. The Trustee shall not be liable for any error of judgment, or for any act done or step taken or omitted by it, in good faith, or for any mistakes of fact or law, or for anything that it may do or refrain from doing in connection herewith except in the case of its willful misconduct, bad faith or grossly negligent performance or omission of its duties. In no event shall the Trustee be liable for special, indirect, punitive or consequential loss or damage of any kind whatsoever (including but not limited to lost profits), even if the Trustee has been advised of the likelihood of such loss or damage and regardless of the form of action.

(b) The Trustee shall not be responsible for the financial condition or business affairs of the Corporation or Guarantors pursuant to any obligations arising under this Indenture, nor shall the Trustee be required to ascertain or inquire as to the performance or observance of any of the terms, conditions, provisions, covenants or agreements of the Corporation or guarantors contained in this Indenture or as to the existence or possible existence of any Default or Event of Default. The Trustee shall not be deemed to have notice of any Default or Event of Default unless a responsible officer of the Trustee has received, at the Corporate Trust Office of the Trustee, written notice of any event which is in fact such a default and such notice references the Notes and this Indenture.

(c) The Trustee shall have no duties or responsibilities except such duties and responsibilities as are specifically set forth in this Indenture and no covenants or obligations shall be read into or implied in this Indenture against the Trustee. In the event of any conflict arising between (i) the provisions of this Indenture to which the Trustee is a party with respect to the duties or responsibilities of the Trustee and (ii) the provisions of any applicable law, the provisions of such applicable law shall prevail. No provision of this Indenture or the Notes shall be deemed to impose any duty or obligation on the Trustee to perform any act or acts, receive or obtain any interest in property or exercise any interest in property, or exercise any right, power, duty or obligation conferred or imposed on it in any jurisdiction in which it shall be illegal, or in which the Trustee shall be unqualified or incompetent due to a change in applicable law, to perform any such act or acts, to receive or obtain any such interest in property or to exercise any such right, power, duty or obligation, or as a result of which the Trustee shall become subject to taxation.

(d) Without limiting the generality of any terms of this section or Article 10 more generally, the Trustee shall have no liability for any delay, failure, inability or unwillingness on the part of the Corporation, a Guarantor or any other applicable Person, to provide and deliver accurate and complete information on a timely basis to the Trustee, or otherwise on the part of any such party to comply with the terms of this Indenture and shall have no liability for any delay, inaccuracy or error in the performance or observance on the Trustee’s part

95

of any of its duties hereunder that is caused by or results from any such inaccurate, incomplete or untimely information received by it, or other failure on the part of any such other party to comply with the terms hereof. The Trustee shall not be liable for failing to perform or delay in performing its specified duties hereunder which results from or is caused by a failure or delay on the part of the Corporation, a Guarantor or any other applicable Person in furnishing necessary, timely and accurate information to the Trustee.

(e) The Trustee shall be under no obligation to exercise or honor any of the rights or powers vested in it by this Indenture, acting on the instructions of the Majority Holders pursuant to this Indenture, unless the Corporation, a Guarantor or any other applicable Person, shall have offered the Trustee security or indemnity reasonably acceptable to the Trustee against costs, expenses and liabilities (including any legal fees) that might reasonably be incurred by it in compliance with such request or direction.

(f) The Trustee shall retain the right not to act and shall not be liable for refusing to act if it is due to a lack of information or instructions or if the Trustee, in its sole judgment, acting reasonably, determines that such act is conflicting with or contrary to the terms of this Indenture or any applicable law or regulation of any jurisdiction or any applicable order or directive of any court, governmental agency or other regulatory body.

(g) The permissive rights of the Trustee enumerated herein shall not be construed as duties.

(h) The Trustee shall not be required to give any bond or surety in respect of the performance of its powers and duties hereunder.

10.6 Evidence and Authority to Trustee, Opinions, etc.

(i) an Officer’s Certificate, stating that any such condition precedent has been complied with in accordance with the terms of this Indenture;

(ii) in the case of a condition precedent the satisfaction of which is, by the terms of this Indenture, made subject to review or examination by a solicitor, an Opinion of Counsel that such condition precedent has been complied with in accordance with the terms of this Indenture; and

(iii) in the case of any such condition precedent the satisfaction of which is subject to review or examination by auditors or accountants, an opinion or report of the Corporation’s auditors whom the Trustee for such purposes hereby approves, that such condition precedent has been complied with in accordance with the terms of this Indenture.

(b) Whenever such evidence relates to a matter other than the authentication and delivery of Notes and the satisfaction and discharge of this Indenture, and except as otherwise

96

specifically provided herein, such evidence may consist of a report or opinion of any solicitor, auditor, accountant, engineer or appraiser or any other appraiser or any other individual whose qualifications give authority to a statement made by such individual, provided that if such report or opinion is furnished by a director, officer or employee of the Corporation it shall be in the form of a statutory declaration. Such evidence shall be, so far as appropriate, in accordance with Section 10.6(a).

(c) Each statutory declaration, certificate, opinion or report with respect to compliance with a condition precedent provided for in this Indenture shall include (i) a statement by the individual giving the evidence that he or she has read and is familiar with those provisions of this Indenture relating to the condition precedent in question, (ii) a brief statement of the nature and scope of the examination or investigation upon which the statements or opinions contained in such evidence are based, (iii) a statement that, in the belief of the individual giving such evidence, he or she has made such examination or investigation as is necessary to enable him or her to make the statements or give the opinions contained or expressed therein, and (iv) a statement whether in the opinion of such individual the conditions precedent in question have been complied with or satisfied.

(d) In addition to its obligations under Section 5.5, the Corporation shall furnish or cause to be furnished to the Trustee at any time if the Trustee reasonably so requires, an Officer’s Certificate certifying that the Corporation has complied with all covenants, conditions or other requirements contained in this Indenture, the non-compliance with which would constitute a Default or an Event of Default, or if such is not the case, specifying the covenant, condition or other requirement which has not been complied with and giving particulars of such non-compliance. The Corporation shall, whenever the Trustee so requires, furnish the Trustee with evidence by way of statutory declaration, opinion, report or certificate as specified by the Trustee as to any action or step required or permitted to be taken by the Corporation or as a result of any obligation imposed by this Indenture.

10.7 Officer’s Certificates Evidence

Except as otherwise specifically provided or prescribed by this Indenture, whenever in the administration of the provisions of this Indenture the Trustee shall deem it necessary or desirable that a matter be proved or established prior to taking or omitting any action hereunder, the Trustee, if acting in good faith, may rely upon an Officer’s Certificate.

(a) employ or retain and act and rely on the opinion or advice of or information obtained from any solicitor, auditor, valuator, engineer, surveyor, appraiser or other adviser or expert, whether obtained by the Trustee or by the Corporation, or otherwise, and shall not be liable for acting, or refusing to act, in good faith on any such opinion or advice and may pay proper and reasonable compensation for all such legal and other advice or assistance as aforesaid; and

(b) employ such agents and other assistants as it may reasonably require for the proper discharge of its duties hereunder, and may pay reasonable remuneration for all services performed for it (and shall be entitled to receive reasonable remuneration for all services performed by it) in the discharge of the trusts hereof and compensation for all disbursements, costs and expenses made or incurred by it in the discharge of its duties hereunder and in the management of the trusts hereof and any solicitors employed or consulted by the Trustee may, but need not be, solicitors for the Corporation.

97

10.9 Trustee May Deal in Notes

Subject to Sections 10.1 and 10.3, if the Trustee becomes a creditor of the Corporation or any Guarantor, this Indenture limits its right to obtain payment of claims in certain cases, or to realize on certain property received in respect of any such claim as security or otherwise. The Trustee will be permitted to engage in other transactions; however, if it acquires any conflicting interest it must eliminate such conflict within 90 days, apply to the Court of Queen’s Bench (Alberta) for permission to continue or resign.

10.10 Investment of Monies Held by Trustee

(a) Unless otherwise provided in this Indenture, any monies held by the Trustee, which, under the trusts of this Indenture may or ought to be invested or which may be on deposit with the Trustee or which may be in the hands of the Trustee, may be invested and reinvested in the name or under the control of the Trustee in any of the securities, accounts, notes certificates and deposits described in the definition of “Cash Equivalents”, and unless and until the Trustee shall have declared the principal of, premium (if any) and interest on the Notes to be due and payable, the Trustee shall so invest such monies only upon receipt of a Corporation Order given no later than 9:00 a.m. (Calgary time) on the day on which the investment is to be made and specifying the specific name of the Cash Equivalent, its CUSIP or ISIN, the amount to be invested and any other information requested by the Trustee. Any such direction received by the Trustee after 9:00 a.m. (Calgary time) or received on a day that is not a Business Day, shall be deemed to have been given prior to 9:00 a.m. (Calgary time) the next Business Day. Pending the investment of any monies as hereinbefore provided, such monies may be deposited in the name of the Trustee in any chartered bank of Canada or any of their Affiliates or, with the consent of the Corporation, in the deposit department of the Trustee or any other loan or trust company authorized to accept deposits under the laws of Canada or any province thereof at the rate of interest, if any, then current on similar deposits. Unless a Corporation Order has been provided in accordance with this Section 10.10(a), any monies held by the Trustee shall remain uninvested and placed in one or more segregated trust accounts to be maintained by the Trustee in the name of the Trustee at any chartered bank in Canada.

(b) Unless and until the Trustee shall have declared the principal of, premium (if any) and interest on any Notes to be due and payable, the Trustee shall pay over to the Corporation all interest received by the Trustee in respect of any investments or deposits made pursuant to a Corporation Order in accordance with the provisions of this Section 10.10.

(c) The amounts held by the Trustee pursuant to this Indenture are the sole risk of the Holder and the Corporation, as the case may be, and, without limiting the generality of the foregoing, the Trustee shall not (i) be held liable to account for any profit or loss of profit to any parties to this Indenture or to any other Person or entity other than at a rate, if any, established from time to time by the Trustee, and (ii) be held responsible or liable for any losses incurred in the investment or sale of any monies or securities.

10.11 Trustee Not Ordinarily Bound

The Trustee shall not be bound to give any notice or take any action or proceeding unless it is required to do so under the terms of this Indenture. The Trustee shall not be deemed to have notice of nor be required to take notice of any Event of Default under this Indenture unless and until the Trustee is notified in writing of such Event of Default by any Holder or the Corporation, which notice will distinctly specify the Event of Default desired to be brought to the attention of the Trustee, or unless a responsible officer of the Trustee has specific knowledge of an Event of Default. In the absence of such notice or knowledge, the Trustee may for all purposes of this Indenture assume that no Event of Default has occurred. Without limiting the foregoing, and except as provided in Section 6.2 and as otherwise specifically provided herein, the Trustee shall not, subject to Section 10.3, be bound to give notice to any Person of the execution hereof, nor to do, observe or perform or see to the observance or performance by the Corporation of any of the

98

obligations herein imposed upon the Corporation or of the covenants on the part of the Corporation herein contained, nor in any way to supervise or interfere with the conduct of the Corporation’s business, unless the Trustee shall have been required to do so in writing by the Holders of not less than 25% of the aggregate principal amount of the Notes then outstanding or by any direction from the Majority Holders, as applicable, in accordance with the terms of this Indenture, and then only after it shall have been funded and indemnified to its satisfaction against all actions, proceedings, claims and demands to which it may render itself liable and all costs, charges, damages and expenses which it may incur by so doing.

10.12 Conditions Precedent to Trustee’s Obligations to Act Hereunder

The obligation of the Trustee to commence or continue any act, action or proceeding for the purpose of enforcing the rights of the Trustee and of the Holders hereunder shall be conditional upon any one or more Holders furnishing when required by notice in writing by the Trustee, notice specifying the act, action or proceeding which the Trustee is requested, directed or authorized to take, sufficient funds to commence or continue such act, action or proceeding and indemnity reasonably satisfactory to the Trustee to protect and hold harmless 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 risk its own funds or otherwise incur liability, financial or otherwise, in the performance of any of its duties or in the exercise of any of its rights or powers unless indemnified as aforesaid. The Trustee may, before commencing or at any time during the continuance of any act, action or proceeding, require the Holders at whose instance it is acting to deposit with the Trustee such Notes held by them for which Notes the Trustee shall issue receipts.

10.13 Authority to Carry on Business

The Trustee represents to the Corporation that at the date of execution and delivery by it of this Indenture it is authorized to carry on the business of a trust company in all Provinces of Canada but if, notwithstanding the provisions of this Section 10.13, it ceases to be so authorized to carry on business, the validity and enforceability of this Indenture and the securities issued hereunder shall not be affected in any manner whatsoever by reason only of such event but the Trustee shall, within 60 days after ceasing to be authorized to carry on the business of a trust company in any Province of Canada, either become so authorized or resign in the manner and with the effect specified in Section 10.2.

10.14 Compensation and Indemnity

The Trustee’s compensation shall not be limited by any law on compensation of a trustee of an express trust.

(b) The Corporation and the Guarantors hereby indemnify and save harmless, on a joint and several basis, the Trustee and its Affiliates, directors, officers, employees, agents and shareholders from and against any and all loss, damages, charges, expenses, claims, demands, actions or liability whatsoever which may be brought against the Trustee or which it may suffer or incur as a result of or arising out of the performance of its duties and obligations hereunder save only in the event of the gross negligence, wilful misconduct or bad faith of the Trustee (as determined by a final, non-appealable order of a court of competent jurisdiction). Without limiting the generality of the foregoing, the obligation to indemnify, defend and save harmless in accordance herewith shall apply in respect of liabilities suffered by, imposed upon, incurred in any way connected with or arising from, directly or indirectly, any environmental laws. This indemnity will survive the termination or

99

discharge of this Indenture and the resignation or removal of the Trustee. The Trustee shall notify the Corporation and the Guarantors promptly of any claim for which it may seek indemnity. The Corporation and the Guarantors shall defend the claim and the Trustee shall cooperate in the defence. The Trustee may have separate Counsel and the Corporation and the Guarantors shall pay the reasonable fees and expenses of such Counsel, on a joint and several basis. The Corporation and the Guarantors need not pay for any settlement made without its consent, which consent must not be unreasonably withheld. This indemnity shall survive the resignation or removal of the Trustee or the discharge of this Indenture.

10.15 Acceptance of Trust

The Trustee hereby accepts the trusts in this Indenture declared and provided for and agrees to perform the same upon the terms and conditions herein set forth and to hold all rights, privileges and benefits conferred hereby and by law in trust for the various Persons who shall from time to time be Holders, subject to all the terms and conditions herein set forth.

10.16 Anti-Money Laundering

The Trustee shall retain the right not to act and shall not be liable for refusing to act if, due to a lack of information or for any other reason whatsoever, the Trustee, in its sole judgment, determines that such act might cause it to be in non-compliance with any applicable anti-money laundering, anti-terrorist, or sanctions legislation, regulation or guideline. Further, should the Trustee, in its sole judgment, determine at any time that its acting under this Indenture has resulted in its being in non-compliance with any applicable anti-money laundering, anti-terrorist, or sanctions legislation, regulation or guideline, then it shall have, subject to Section 10.2, the right to resign on 10 days’ prior written notice sent to all parties hereto; provided that (a) the written notice shall describe the circumstances of such non-compliance to the extent permitted by applicable anti-money laundering, anti-terrorist, or sanctions legislation, regulation or guideline and (b) if such circumstances are rectified to the Trustee’s satisfaction within such 10 day period, then such resignation shall not be effective.

party has assured itself that such individual understands and has consented to the aforementioned uses and disclosures.

10.18 Protection of Trustee

The Trustee shall not be liable for any delay (or any related consequence) in crediting an account with an amount required under this Indenture to be paid by the Trustee if it has taken all necessary steps as soon as reasonably practicable to comply with the regulations or operating procedures of any recognized clearing or settlement system used by the Trustee for that purpose. The Trustee shall be entitled to treat a facsimile, pdf or e-mail communication or communication by other similar electronic means in a form satisfactory to the Trustee from a Person purporting to be (and whom such Trustee, acting reasonably, believes in good faith to be) the authorized representative of the Corporation as sufficient instructions and authority of the Corporation for the Trustee to act and shall have no duty to verify or confirm that Person is so authorized.

2.4 Guarantee Absolute and Unconditional

The obligations of each Guarantor under this Subsidiary Guarantee are independent of the obligations of the Corporation under the Notes and the Indenture, and a separate action or actions may be brought and prosecuted against such Guarantor to enforce this Subsidiary Guarantee, irrespective of whether any action is brought against the Corporation or any other Guarantor or whether the Corporation or any other Guarantor is joined in any such action or actions. The liability and obligations of each Guarantor hereunder shall be continuing, unconditional and absolute and, without limiting the generality of the foregoing, shall not be released, discharged, limited or otherwise affected by:

(b) any extension, other indulgence, renewal, settlement, discharge, compromise, waiver, subordination or release in respect of any Indenture Obligation, the Indenture, the Notes or otherwise;

(c) any modification or amendment of or supplement to the Indenture Obligations;

(g) any limitation, postponement, prohibition, subordination or other restriction on the right of the Beneficiaries to payment of the Indenture Obligations;

(h) any release, substitution or addition of any other guarantor of the Indenture Obligations;

(i) any defence arising by reason of any failure of the Beneficiaries to make any presentment or protest or to give any other notice, including notice of all of the following: acceptance of this Subsidiary Guarantee, partial payment or non-payment of all or any part of the Indenture Obligations, occurrence of a Default of Event of Default under the provisions of the Indenture or the Notes and the existence, creation, or incurring of new or additional Indenture Obligations;

(k) any defence arising by reason of the invalidity, illegality or lack of enforceability of the Indenture Obligations or any part thereof or of any security or guarantee in support thereof, or by reason of any incapacity, lack of authority or other defence of the Corporation, the other Guarantors or any other Person, or by reason of any limitation, postponement or prohibition on the Beneficiaries’ rights to payment, or the cessation from any cause whatsoever of the liability of the Corporation, the other Guarantors or any other Person with respect to all or any part of the Indenture Obligations (other than irrevocable payment to the Beneficiaries in full, in cash, of the Indenture Obligations), or by reason of any act or omission of the Beneficiaries or others which directly or indirectly results in the discharge or release of the Corporation, the other Guarantors or any other Person or of all or any part of the Indenture Obligations or any security or guarantee therefor, whether by contract, operation of law or otherwise;

(m) the assignment of any right, title or interest of the Trustee or any Holder in the Indenture or any Note to any other Person; or

(n) any other law, event or circumstance or any other act or failure to act or delay of any kind by the Corporation, the other Guarantors, the Beneficiaries or any other Person, which might, but for the provisions of this Section, constitute a legal or equitable defence to or discharge, limitation or reduction of the Guarantor’s obligations hereunder, other than as a result of the payment or extinguishment in full of the Indenture Obligations.

The foregoing provisions apply and the foregoing waivers, to the extent permitted under applicable law, shall be effective even if the effect of any action or failure to take action by the Beneficiaries is to destroy or diminish the Guarantor’s subrogation rights, the Guarantor’s right to proceed against the Corporation or the other Guarantors for reimbursement, the Guarantor’s right to recover contribution from any other guarantor or any other right or remedy of the Guarantor.

Article 5
