(b)

If there occurs a material change in GAAP, including as a result of a conversion to or adoption of International Financial Reporting Standards, and such change would require disclosure under GAAP in the financial statements of the Issuer 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 Issuer shall notify the Trustee of such change (an "Accounting Change").

The Accounting Change Notice shall be delivered to the Trustee within 90 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.

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 Issuer within the applicable time period described above, 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.

All Notes will be substantially identical except as to denomination and except as may otherwise be provided in or pursuant to this Indenture or the Supplemental Indenture establishing Additional Notes. Not all Notes need to be issued at the same time, and, except to the extent otherwise provided herein, Additional Notes may be issued from time to time, at the option of the Issuer without the consent of any Holder.

(d)

The Notes may be in different denominations and forms and may contain such variations of tenor and effect, not inconsistent with the provisions of this Indenture, as are incidental to such differences of denomination and form, including variations in the provisions for the exchange of Notes of different denominations or forms and in the provisions for the registration or transfer of Notes.

(e)

Additional Notes will bear the same designation and designating letters as those applied to such similar 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.

(f)

All Notes which may at any time be issued under this Indenture and the certificate of the Trustee endorsed on such Notes may be in English or any other language or languages or any combination thereof, and may be in the form or forms provided in any Supplemental Indenture or in such other language or languages and in such form or forms as the Board of Directors determines at the time of issue of any Additional Notes, as approved by the Trustee, the approval of which will be conclusively evidenced by its certification of the Notes.

(g)

If any provision of the Notes in a language other than English is susceptible of an interpretation different from the equivalent provision of the English language, the interpretation of such provision in the English language will be determinative.

(h)

The Notes may be typed, engraved, printed, lithographed or reproduced in a different form, or partly in one form and partly in another, as the Issuer may determine. The execution of any such Notes by the Issuer and the certification by the Trustee of any such Notes will be conclusive evidence that such Notes are Notes authorized by this Indenture.

(i)

All Global Certificates authenticated and delivered by the Trustee shall bear a legend in substantially the following form:

"THIS NOTE IS A GLOBAL NOTE WITHIN THE MEANING OF THE INDENTURE HEREIN REFERRED TO AND IS REGISTERED IN THE NAME OF A DEPOSITORY OR A NOMINEE THEREOF. THIS NOTE MAY NOT BE TRANSFERRED TO OR EXCHANGED FOR NOTES REGISTERED IN THE NAME OF ANY PERSON OTHER THAN THE DEPOSITORY OR A NOMINEE THEREOF AND NO SUCH TRANSFER MAY BE REGISTERED EXCEPT IN THE LIMITED CIRCUMSTANCES DESCRIBED IN THE INDENTURE. EVERY NOTE AUTHENTICATED AND DELIVERED UPON REGISTRATION OF, TRANSFER OF, OR IN EXCHANGE FOR, OR IN LIEU OF, THIS NOTE SHALL BE A GLOBAL NOTE SUBJECT TO THE FOREGOING, EXCEPT IN SUCH LIMITED CIRCUMSTANCES DESCRIBED IN THE INDENTURE.

Unless this certificate is presented by an authorized representative of CDS Clearing and Depository Services Inc. ("CDS") to Perpetual Energy Inc. (the "Issuer") 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 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 certificate herein and it is a violation of its rights for another person to hold, transfer or deal with this certificate.

UNLESS PERMITTED UNDER SECURITIES LEGISLATION, THE HOLDER OF THIS SECURITY MUST NOT TRADE THE SECURITY BEFORE [insert date that is four months plus one day from date of the Closing Date]."

2.3

Execution, Authentication and Delivery of Notes

(a)

All Notes shall be signed (either manually or by electronic or facsimile signature) by any two authorized directors or officers of the Issuer, holding office at the time of signing. An electronic or facsimile signature upon a Note shall for all purposes of this Indenture be deemed to be the signature of the Person whose signature it purports to be. Notwithstanding that any Person whose signature, either manual or in facsimile or other electronic means, appears on a Note as a director or officer may no longer hold such office at the date of the Note or at the date of the certification and delivery thereof, such Note shall be valid and binding upon the Issuer and entitled to the benefits of this Indenture.

(b)

Subject to the terms and conditions in this Indenture, the Trustee, from time to time upon receipt by the Trustee of a Written Order, will authenticate and make available Notes in the manner specified in the Written Order, without the Trustee receiving any consideration thereof.

(c)

No Notes will be entitled to any right or benefit under this Indenture or be valid or obligatory for any purpose unless such Notes have been authenticated by or on behalf of the Trustee substantially in the form provided for herein or in the relevant Supplemental Indenture. Such authentication upon any Notes will be conclusive evidence, and the only evidence, that such Notes have been duly authenticated, issued and delivered and that the Holder is entitled to the benefits hereof.

(d)

The certificate by or on behalf of the Trustee authenticating Notes will not be construed as a representation or warranty of the Trustee as to the validity of this Indenture or of any Notes or its issuance (except the due certification thereof by the Trustee) or as to the performance by the Issuer of its obligations under this Indenture or the Notes and the Trustee will be in no respect liable or answerable for the use made of the proceeds of such Notes. The certificate by or on behalf of the Trustee on Notes issued under this Indenture will constitute a representation and warranty by the Trustee that such Notes have been duly authenticated by and on behalf of the Trustee pursuant to the provisions of this Indenture.

(e)

The Trustee shall initially authenticate one or more Global Certificates for original issue on the Issue Date in an aggregate principal amount of $150,000,000 upon a Written Order of the Issuer signed by an executive officer of the Issuer (an "Authentication Order"). After the Issue Date, subject to Section 6.10, the Issuer may issue, from time to time, and the Trustee shall authenticate upon receipt of an Authentication Order, Additional Notes for original issue, the aggregate principal amount of any particular issue of Additional Notes to be such aggregate principal amount as is specified in such order. Except as provided in Section 6.10, there is no limit on the amount of Additional Notes that may be issued hereunder. Each such Authentication Order shall specify the principal amount of Notes to be authenticated and the date on which such Notes are to be authenticated. The aggregate principal amount of Notes outstanding at any time may not exceed the aggregate principal amount specified in the Authentication Orders except as provided in Section 2.9.

2.4

Registrar and Paying Agent

(a)

The Issuer shall maintain an office or agency where Notes may be presented for registration of transfer or for exchange ("Registrar") and an office or agency where Notes may be surrendered for payment ("Paying Agent"). The Registrar shall keep a register of the Notes and of their transfer and exchange.

(b)

The Issuer may appoint one or more co-Registrars and one or more additional paying agents in such other locations as it shall determine. The term "Registrar" includes any co-Registrar and the term "Paying Agent" includes any additional paying agent. The Issuer may change any Paying Agent or Registrar without notice to any Holder. The Issuer will notify the Trustee in writing of the name and address of any Registrar or Paying Agent which is not a party to this Indenture. If the Issuer fails to appoint or maintain another entity as Registrar or Paying Agent, the Trustee shall act as such. The Issuer or any of its Subsidiaries may act as Paying Agent or Registrar.

(c)

The Issuer initially appoints CDS to act as Depository with respect to the Notes.

(d)

The Issuer initially appoints the Trustee at its corporate office in Calgary, Alberta and its co-agent in Toronto, Ontario to act as the Registrar and Paying Agent with respect to the Notes.

2.5

Paying Agent to Hold Money in Trust

The Issuer shall require each Paying Agent other than the Trustee, to agree in writing that the Paying Agent will, and the Trustee when acting as Paying Agent agrees that it will, hold in trust, for the benefit of the Holders or the Trustee all money held by the Paying Agent for the payment of principal, Applicable Premium, if any, or interest on the Notes and shall notify the Trustee of any default by the Issuer in making any such payment. While any such default continues, the Trustee may require a Paying Agent to pay all money held by it to the Trustee and to account for any money disbursed by it. The Issuer at any time may require a Paying Agent to pay all money held by it to the Trustee. Upon payment over to the Trustee, the Paying Agent (if other than the Issuer or a Subsidiary) shall have no further liability for the money. If the Issuer or a Subsidiary acts as Paying Agent, it shall segregate and hold in a separate trust fund for the benefit of Holders all money held by it as Paying Agent. Upon any bankruptcy or reorganization proceedings relating to the Issuer, the Trustee shall serve as Paying Agent for the Notes.

2.6

Book Entry Only Notes

(a)

Subject to Section 4.2(b), Notes shall be issued as Book Entry Only Notes represented by one or more Global Certificates. Each Global Certificate certified in accordance with this Indenture and any Supplemental Indenture shall be registered in the name of the Depository designated for such Global Certificate or a nominee thereof and delivered to such Depository or a nominee thereof or custodian therefor, and each such Global Certificate shall constitute a single Note for all purposes of this Indenture and all Supplemental Indentures. Beneficial interests in a Global Certificate will not be shown on the register or the records maintained by the Depository but will be represented through book entry accounts of Participants on behalf of the beneficial owners of the Global Certificates in accordance with the rules and procedures of the Depository. None of the Issuer or the Trustee shall have any responsibility or liability for any aspects of the records relating to or payments made by any Depository on account of the beneficial interest in any Global Certificates or for maintaining, reviewing or supervising any records relating to such beneficial interests. Except as otherwise provided in this Indenture, owners of beneficial interests in any Global Certificates shall not be entitled to have Notes registered in their names, shall not receive or be entitled to receive definitive Notes and shall not be considered owners or holders thereof under this Indenture or any Supplemental Indenture. Nothing herein or in a Supplemental Indenture shall prevent the beneficial owners in Global Certificates from voting such Notes using duly executed proxies.

(b)

Every Note authenticated and delivered upon registration of transfer of a Global Certificate, or in exchange for or in lieu of a Global Certificate or any portion thereof, shall be authenticated and delivered in the form of, and shall be, a Global Certificate, unless such Note is registered in the name of a Person other than the Depository for such Global Certificates or a nominee thereof.

2.7

Global Certificates

Notes issued to a Depository in the form of Global Certificates shall be subject to the following:

(a)

the Trustee may deal with such Depository as the authorized representative of the Beneficial Holders of such Notes;

(b)

the rights of the Beneficial Holders of such Notes shall be exercised only through such Depository and the rights of Beneficial Holders shall be limited to those established by applicable law and agreements between the Depository and the Participants and between such Participants and Beneficial Holders, and must be exercised through a Participant in accordance with the rules and procedures of the Depository;

(c)

whenever this Indenture requires or permits actions to be taken based upon instructions or directions of Holders evidencing a specified percentage of the outstanding Notes, the Depository shall be deemed to be counted in that percentage to the extent that it has received instructions to such effect from Beneficial Holders or Participants;

(d)

such Depository will make book-entry transfers among the direct Participants of such Depository and will receive and transmit distributions of principal, Applicable Premium and interest on the Notes to such direct Participants; and

(e)

the direct Participants of such Depository shall have no rights under this Indenture or under or with respect to any of the Notes held on their behalf by such Depository, and such Depository may be treated by the Trustee and its agents, employees, officers and directors as the absolute owner of the Notes represented by such Global Certificates for all purposes whatsoever.

Notwithstanding anything to the contrary set out herein, all Global Certificates issued to the Depository may be surrendered to the Trustee for an electronic position on the register of Noteholders to be maintained by the Trustee in accordance with Article 4. All Notes maintained in such electronic position will be valid and binding obligations of the Issuer, entitling the registered holders thereof to the same benefits as those registered holders who hold Global Notes in physical form. This Indenture and the provisions contained herein will apply, mutatis mutandis, to such Global Notes held in such electronic position.

2.8

Interim Notes

Pending the delivery of definitive Notes to the Trustee, the Issuer may issue and the Trustee certify in lieu thereof (but subject to the same provisions, conditions and limitations as set forth in this Indenture) interim printed, mimeographed or typewriter Notes in such forms and in such denominations and signed in such manner as provided herein, entitling the holders thereof to definitive Notes when the same are ready for delivery; or the Issuer may execute and the Trustee certify a temporary Note for the whole principal amount of Notes then authorized to be issued hereunder and deliver the same to the Trustee and thereupon the Trustee may issue its own interim certificates in such form and in such amounts, not exceeding in the aggregate the principal amount of the temporary Note so delivered to it, as the Issuer and the Trustee may approve entitling the holders thereof to definitive Notes when the same are ready for delivery; and, when so issued and certified, such interim or temporary Notes or interim certificates shall, for all purposes but without duplication, rank in respect of this Indenture equally with Notes duly issued hereunder and, pending the exchange thereof for definitive Notes, the holders of the interim or temporary Notes or interim certificates shall be deemed without duplication to be Holders and entitled to the benefit of this Indenture to the same extent and in the same manner as though the said exchange had actually been made. Forthwith after the Issuer shall have delivered the definitive Notes to the Trustee, the Trustee shall cancel such temporary Notes, if any, and shall call in for exchange all interim Notes or certificates that shall have been issued and forthwith after such exchange shall cancel the same. No charge shall be made by the Issuer or the Trustee to the holders of such interim or temporary Notes or interim certificates for the exchange thereof. All interest paid upon interim or temporary Notes or interim certificates shall be noted thereon as a condition precedent to such payment unless paid by cheque to the registered holders thereof.

2.9

Mutilation, Loss, Theft or Destruction

In case any of the Notes issued hereunder shall become mutilated or be lost, stolen or destroyed, the Issuer, in its discretion, may issue, and thereupon the Trustee shall certify and deliver, a new Note upon surrender and cancellation of the mutilated Note, or in the case of a lost, stolen or destroyed Note, in lieu of and in substitution for the same, and the substituted Note shall be in a form approved by the Trustee and shall be entitled to the benefits of this Indenture and rank equally in accordance with its terms with all other Notes issued or to be issued hereunder. In case of loss, theft or destruction the applicant for a substituted Note shall furnish to the Issuer and to the Trustee such evidence of the loss, theft or destruction of the Note as shall be satisfactory to them in their discretion and shall also furnish an indemnity and surety bond satisfactory to them in their discretion. The applicant shall pay all reasonable expenses incidental to the issuance of any substituted Note.

2.10

Concerning Interest

(a)

All Notes issued hereunder, whether originally or upon exchange or in substitution for previously issued Notes which are interest bearing, shall bear interest (i) from and including their issue date, or (ii) from and including the last Interest Payment Date to which interest shall have been paid or made available for payment on the outstanding Notes, whichever shall be the later, in all cases, to and excluding the next Interest Payment Date.

(b)

Subject to accrual of any interest on unpaid interest from time to time, interest on such Note will cease to accrue from the earlier of (i) the Maturity of such Note and (ii) if such Note is called for redemption, the date fixed for redemption; unless, in each case, upon due presentation and surrender of such Note for payment on or after the Maturity or the date fixed for redemption, as the case may be, such payment is improperly withheld or refused.

(c)

If the date for payment of any amount of principal, Applicable Premium or interest is not a Business Day at the place of payment, then payment will be made on the next Business Day and Holders will not be entitled to any further interest on such principal, or to any interest on such interest, Applicable Premium or other amount so payable, in respect of the period from the date for payment to such next Business Day.

(d)

Wherever in this Indenture or the Notes 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 Notes, 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.

(e)

Unless otherwise specifically provided in this Indenture, interest shall be computed on the basis of a year of 365 days. Whenever interest is computed on the basis of a year (the "deemed year") which contains fewer days than the actual number of days in the calendar year of calculation, such rate of interest shall be expressed as a yearly rate for purposes of the Interest Act (Canada) by multiplying such rate of interest by the actual number of days in the calendar year of calculation and dividing it by the number of days in the deemed year.

2.11

Notes to Rank Equal in Right of Payment

The Notes will be direct unsecured obligations of the Issuer. Each Note will rank equal in right of payment with each other Note (regardless of their actual date or terms of issue) and, subject to statutory preferred exceptions, will rank at least equal in right of payment with all other present and future unsecured indebtedness of the Issuer.

2.12

Payments of Amounts Due on Maturity

(a)

The following provisions shall apply to Notes:

(i)

the Issuer will establish and maintain with the Trustee a Maturity Account for the Notes. On or before 11:00 a.m. (Calgary time) on the Business Day before the date of Maturity, the Issuer will deposit in the applicable Maturity Account by wire transfer or certified cheque an amount sufficient to pay the amount payable in respect of such Notes (less any tax required by law to be deducted). The Issuer (either directly or through the Trustee or any agent of the Trustee) will pay to each Holder entitled to receive payment, the principal amount of, and Applicable Premium (if any) on, the Notes, upon surrender of the Notes at any branch of the Trustee designated for such purpose from time to time by the Issuer and the Trustee. The deposit or making available of such amounts to the applicable Maturity Account will satisfy and discharge the liability of the Issuer for the 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 tax deducted as aforesaid) and such Notes will thereafter not be considered as outstanding under this Indenture and such Holder will have no other right than to receive out of the money so deposited or made available the amount to which it is entitled. Failure to make a deposit or make funds available as required to be made pursuant to this Section 2.12(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; and

(ii)

in the case of Global Certificates, on or before 9:00 a.m. (Calgary time) on the Business Day before the date of Maturity, the Issuer will deliver to the Depository by electronic funds transfer an amount sufficient to pay the amount payable in respect of such Global Certificates (less any tax required by law to be deducted). The Issuer will pay to the Depository the principal amount of, and Applicable Premium (if any) on, the Global Certificates, against receipt of the Global Certificate. The delivery of such electronic funds to the Depository will satisfy and discharge the liability of the Issuer for the Notes to which the electronic funds relates to the extent of the amount deposited or made available (plus the amount of any tax deducted as aforesaid) and such Notes will thereafter not be considered as outstanding under this Indenture unless such electronic funds transfer is not received. Failure to make delivery of funds available as required pursuant to this Section 2.12(a)(ii) 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.

(b)

Notwithstanding the foregoing, (i) all payments in excess of $25 million (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; and (ii) in the event that payment must be made to the Depository, the Issuer shall remit payment to the Trustee by LVTS. The Trustee shall have no obligation to disburse funds pursuant to this Section 2.12 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 date of Maturity. 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.

2.13

U.S. Legend on Notes

(a)

The Notes have not been and will not be registered under the 1933 Act or under any state securities laws. Certificates (including, without limitation, Global Certificates) representing Notes sold pursuant to Rule 144A under the 1933 Act, as well as all Notes issued in exchange for or in substitution of the foregoing securities, shall bear, unless otherwise directed by the Issuer, the following legend (the "U.S. Legend"):

"THE SECURITY EVIDENCED HEREBY HAS NOT BEEN REGISTERED UNDER THE UNITED STATES SECURITIES ACT OF 1933, AS AMENDED (THE "U.S. SECURITIES ACT"), OR ANY STATE SECURITIES LAWS. THE HOLDER OF THE SECURITY EVIDENCED HEREBY AGREES ON ITS OWN BEHALF AND ON BEHALF OF ANY INVESTOR ACCOUNT FOR WHICH IT HOLDS THE SECURITY, FOR THE BENEFIT OF THE ISSUER, THAT (A) THE SECURITY EVIDENCED HEREBY MAY BE OFFERED, SOLD OR OTHERWISE TRANSFERRED ONLY PURSUANT TO AN EFFECTIVE REGISTRATION STATEMENT UNDER THE U.S. SECURITIES ACT OR AN EXEMPTION OR EXCLUSION FROM THE REGISTRATION REQUIREMENTS OF THE U.S. SECURITIES ACT AND APPLICABLE STATE SECURITIES LAWS AND (B) THE HOLDER WILL, AND EACH SUBSEQUENT HOLDER IS REQUIRED TO, NOTIFY ANY PURCHASER OF THE SECURITY EVIDENCED HEREBY OF THE RESALE RESTRICTIONS SET FORTH IN CLAUSE (A) ABOVE."

provided that, if any Notes or beneficial interests in Notes represented by a Global Certificate are being sold in accordance with Rule 904 of Regulation S, and if the Issuer is a "foreign issuer" within the meaning of Regulation S at the time of sale, the legend may be removed with respect to the particular Notes or beneficial interests in Notes represented a Global Certificate being sold, by providing a declaration to the Trustee, in such form as the Issuer may prescribe from time to time, together with any other evidence, which may include, without limitation, an opinion of counsel of recognized standing reasonably satisfactory to the Issuer, required by the Issuer or the Trustee, to the effect that the legend is no longer required under the 1933 Act; and

provided further that, if any Notes or beneficial interests in Notes represented by a Global Certificate are being sold under Rule 144 under the 1933 Act, if available, the legend may be removed with respect to the particular Notes or beneficial interests in Notes represented by a Global Certificate being sold, by delivering to the Trustee an opinion of counsel of recognized standing reasonably satisfactory to the Issuer, to the effect that the legend is no longer required under applicable requirements of the U.S. Securities Act or state securities laws."

(b)

Prior to the issuance of the Notes, the Issuer shall notify the Trustee, in writing, concerning which Notes are to bear the U.S. Legend or, if any Notes are to be represented by a Global Certificate, which beneficial interests in Notes represented by such Global Certificate, if any, are to be represented by a Global Certificate that bears the U.S. Legend. The Trustee will thereafter maintain a list of all Holders from time to time of Legended Notes.

2.14

Payment of Interest

(a)

As interest becomes due on each Note (except on redemption, when interest may at the option of the Issuer be paid upon surrender of such Note), the Issuer, either directly or through the Trustee or any agent of the Trustee, shall send or forward by prepaid ordinary mail, electronic transfer of funds or such other means as may be agreed to by the Trustee, payment of such interest (less any tax required to be withheld therefrom) to the order of the Holder of such Note appearing on the registers maintained by the Trustee at the close of business on the fifth Business Day (or if the Note ceases to be represented by a Global Certificate, then the tenth Business Day) prior to the applicable Interest Payment Date and addressed to the Holder at the Holder's last address appearing on the register (or in the case of joint Holders, to such address of one of the joint Holders), unless such Holder otherwise directs. If payment is made by cheque, such cheque shall be forwarded at least three days prior to each date on which interest becomes due and if payment is made by other means (such as electronic transfer of funds, provided the Trustee must receive confirmation of receipt of funds prior to being able to wire funds to Holders), such payment shall be made in a manner whereby the Holder receives credit for such payment on the date such interest on such Note becomes due. The mailing of such cheque or the making of such payment by other means shall, to the extent of the sum represented thereby, plus the amount of any tax withheld as aforesaid, satisfy and discharge all liability for interest on such Note, unless in the case of payment by cheque, such cheque is not paid at par on presentation. In the event of non-receipt of any cheque for or other payment of interest by the Person to whom it is so sent as aforesaid, the Issuer will issue to such Person a replacement cheque or other payment for a like amount upon being furnished with such evidence of non-receipt as it shall reasonably require and upon being indemnified to its satisfaction. Notwithstanding the foregoing, if the Issuer is prevented by circumstances beyond its control (including, without limitation, any interruption in mail service) from making payment of any interest due on each Note in the manner provided above, the Issuer may make payment of such interest or make such interest available for payment in any other manner acceptable to the Trustee with the same effect as though payment had been made in the manner provided above. If payment is made through the Trustee, by 11:00 a.m. (Calgary time) at least one Business Day prior to each Interest Payment Date or to the date of mailing the cheques for the interest due on an Interest Payment Date, whichever is earlier, the Issuer shall deliver sufficient funds to the Trustee by electronic transfer or certified cheque or make such other arrangements for the provision of funds as may be agreeable between the Trustee and the Issuer in order to effect such interest payment hereunder.

(b)

So long as the Notes or any portion thereof are represented by a Global Certificate, then all payments of interest on the Global Certificate shall be made by electronic funds transfer made payable to the Depository or its nominee for subsequent payment to Beneficial Holders of the applicable interests in that Global Certificate, unless the Issuer and the Depository otherwise agree. None of the Issuer, the Trustee or any agent of the Trustee for any Note represented by a Global Certificate will be liable or responsible to any Person for any aspect of the records related to or payments made on account of beneficial interests in any Global Certificate or for maintaining, reviewing, or supervising any records relating to such beneficial interests.

(c)

Notwithstanding the foregoing, (i) all payments in excess of $25 million (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; and (ii) in the event that payment must be made to the Depository, the Issuer shall remit payment to the Trustee by LVTS. The Trustee shall have no obligation to disburse funds pursuant to this Section 2.14(c) 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 with respect to such Interest Payment 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.

2.15

Record of Payment

The Trustee will maintain accounts and records evidencing any payment, by it on behalf of the Issuer, of principal, Applicable Premium (if any) and interest in respect of Notes, which accounts and records will constitute, in the absence of manifest error, prima facie evidence of such payment.

2.16

Representation Regarding Third Party Interest

The Issuer hereby represents to the Trustee that any account to be opened by, or interest to held by, the Trustee in connection with this Indenture, for or to the credit of the Issuer, either (i) is not intended to be used by or on behalf of any third party; or (ii) is intended to be used by or on behalf of a third party in which case the Issuer hereby agrees to complete, execute and deliver forthwith to the Trustee a declaration, in the Trustee's prescribed form or in such other form as may be reasonably satisfactory to it, as to the particulars of such third party.

With respect to Notes issuable in whole or in part as one or more Global Certificates, the Issuer shall cause to be kept by and at the principal office of the Trustee in Calgary, Alberta and by the Trustee or such other Registrar as the Issuer, with the approval of the Trustee, may appoint at such other place or places, if any, as the Issuer may designate with the approval of the Trustee, a register in which shall be entered the name and address of the Holder of each such Global Certificate (being the Depository, or its nominee, for such Global Certificate) as the Holder thereof and particulars of the Global Certificate held by it, and of all transfers thereof. If any Notes are at any time not represented by a Global Certificate, the provisions of Section 4.1 shall govern with respect to registrations and transfers of such Notes.

(b)

Notwithstanding any other provision of this Indenture, a Global Certificate may not be transferred by the Holder thereof and, accordingly, no definitive Notes shall be issued to Beneficial Holders except in the following circumstances or as otherwise specified in a resolution of the Trustee, a Board Resolution of the Issuer, or an Officers' Certificate:

(i)

Global Certificates may be transferred if CDS ceases to be a clearing agent or otherwise ceases to be eligible to be a depository and the Issuer is unable to locate a qualified successor;

(ii)

Global Certificates may be transferred 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;

(iii)

Global Certificates may be transferred at any time after the Depository for such Global Certificates (i) has notified the Trustee, or the Issuer has notified the Trustee, that it is unwilling or unable to continue as Depository for such Global Certificates, or (ii) ceases to be eligible to be a Depository, provided that at the time of such transfer the Issuer has not appointed a successor Depository for such Global Certificates;

(iv)

Global Certificates may be transferred at any time after the Issuer has determined, in its sole discretion, to terminate the book-entry only registration system in respect of such Global Certificates and has communicated such determination to the Trustee in writing;

(v)

Global Certificates may be transferred at any time after the Trustee has determined that an Event of Default has occurred and is continuing with respect to the Notes issued as a Global Certificate, provided that Beneficial Holders representing, in the aggregate, not less than 50% of the aggregate outstanding principal amount of the Notes advise the Depository in writing, through the Participants, that the continuation of the book-entry only registration system for Notes is no longer in their best interests;

(vi)

Global Certificates may be transferred if the book-entry only registration system ceases to exist; or

(vii)

Global Certificates may be transferred if such transfer is required by applicable law, as determined by the Issuer and Counsel.

(c)

With respect to the Global Certificates, unless and until definitive Notes have been issued to Beneficial Holders pursuant to Section 4.2(b):

(i)

the Issuer and the Trustee may deal with the Depository for all purposes (including paying interest on the Notes) as the sole holder of Notes and the authorized representative of the Beneficial Holders;

(ii)

the rights of the Beneficial Holders shall be exercised only through the Depository and shall be limited to those established by law and agreements between such Beneficial Holders and the Depository or the Participants;

(iii)

the Depository will make book-entry transfers among the Participants; and

(iv)

whenever this Indenture requires or permits actions to be taken based upon instruction or directions of Holders evidencing a specified percentage of the outstanding Notes, the Depository shall be deemed to be counted in that percentage only to the extent that it has received instructions to such effect from the Beneficial Holders or the Participants, and has delivered such instructions to the Trustee.

(d)

Whenever a notice or other communication is required to be provided to Holders, unless and until definitive Note(s) have been issued to Beneficial Holders pursuant to this Section 4.2, the Trustee shall provide all such notices and communications to the Depository and the Depository shall deliver such notices and communications to such Beneficial Holders in accordance with Applicable Securities Legislation. Upon the termination of the book-entry only registration system on the occurrence of one of the conditions specified in Section 4.2(b) with respect to Notes issued hereunder, the Trustee shall notify all applicable Beneficial Holders, through the Depository, of the availability of definitive Notes. Upon surrender by the Depository of the certificate(s) representing the Global Certificates and receipt of new registration instructions from the Depository, the Trustee shall deliver the definitive Notes 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 4.1 and the remaining Sections of this Article 4.

(e)

It is expressly acknowledged that transfer of beneficial ownership in any Book Entry Only Notes represented by a Global Certificate will be affected only (a) with respect to the interests of participants ("Participants"), through records maintained by the Depository or its Nominee for the Global Certificate, and (b) with respect to interests of Persons other than Participants, through records maintained by Participants. Beneficial Holders of Book Entry Only Notes who are not Participants but who desire to purchase, sell or otherwise transfer ownership of or other interest in Book Entry Only Notes represented by a Global Certificate may do so only through a Participant.

(f)

Notwithstanding anything to the contrary contained herein, transfers of Notes, including, without limitation, transfers of beneficial interests in Notes represented by a Global Certificate, shall only be made in accordance with applicable law and the provisions hereof, including, without limitation, the transfer restrictions described in the U.S. Legend contained in Section 2.13 hereof.

4.3

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 in that behalf required by this Indenture or by law, to be entered on the register as the owner of such Note free from all equities or rights of set-off or counterclaim between the Issuer and the transferor or any previous Holder of such Note, save in respect of equities of which the Issuer is required to take notice by law.

4.4

No Notice of Trusts

Neither the Issuer nor the Trustee nor any Registrar shall be bound to take notice of or see to the execution of any trust (other than that created by this Indenture) whether express, implied or constructive, in respect of any Note, and may transfer the same on the direction of the Person registered as the Holder thereof, whether named as Trustee or otherwise, as though that Person were the beneficial owner thereof.

4.5

Registers Open for Inspection

The registers referred to in Sections 4.1, 4.2 and 4.3 shall, subject to applicable law, at all reasonable times be open for inspection by the Issuer, the Trustee or any Holder. Every Registrar, including the Trustee, shall from time to time when requested so to do by the Issuer or by the Trustee, in writing, furnish the Issuer or the Trustee, as the case may be, with a list of names and addresses of Holders of Notes entered on the register kept by them and showing the principal amount and serial numbers of the Notes held by each such Holder, provided the Trustee shall be entitled to charge a reasonable fee to provide such a list.

4.6

Exchanges of Notes

(a)

Subject to Section 4.7, Notes in any authorized form or denomination, other than Global Certificates, may be exchanged, upon reasonable notice, for Notes in any other authorized form or denomination, of the same series and date of Maturity, bearing the same interest rate and of the same aggregate principal amount as the Notes so exchanged.

(b)

In respect of exchanges of Notes permitted by Section 4.6(a), Notes may be exchanged only at the principal offices of the Trustee in the City of Calgary, Alberta or in the City of Toronto, Ontario or at such other place or places, if any, as may be specified in the Notes and at such other place or places as may from time to time be designated by the Issuer with the approval of the Trustee. Any Notes tendered for exchange shall be surrendered to the Trustee. The Issuer shall execute and the Trustee shall certify all Notes necessary to carry out exchanges as aforesaid. All Notes surrendered for exchange shall be cancelled.

(c)

Notes issued in exchange for Notes which at the time of such issue have been selected or called for redemption at a later date shall be deemed to have been selected or called for redemption in the same manner and shall have noted thereon a statement to that effect, provided that:

(i)

Notes which have been selected or called for redemption may not be exchanged for Notes of larger denominations; and

(ii)

if a Note that has been selected or called for redemption in part is presented for exchange for Notes of smaller denominations, the Trustee will designate, as it may deem equitable, particular Notes of those issued in exchange, which will be deemed to have been selected or called for redemption, in whole or in part, and the Trustee will note on such Notes a statement to that effect.

4.7

Closing of Registers

(a)

Neither the Issuer nor the Trustee nor any Registrar shall be required to:

(i)

make transfers or exchanges of, any Notes on any Interest Payment Date for such Notes or during the 10 preceding Business Days;

(ii)

make transfers or exchanges of, any Notes on the day of any selection by the Trustee of Notes to be redeemed or during the 10 preceding Business Days; or

(iii)

make exchanges of any Notes which have been selected or called for redemption unless upon due presentation thereof for redemption such Notes are not redeemed.

(b)

Subject to any restriction provided in this Indenture, the Issuer with the approval of the Trustee, may at any time close any register for Notes, other than those kept at the principal office of the Trustee in Calgary, Alberta and its co-agent in Toronto, Ontario 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.

4.8

Charges for Registration, Transfer and Exchange

For each Note exchanged, registered, transferred or discharged from registration, 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 Issuer), 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, transfer or discharge from registration as a condition precedent thereto. Notwithstanding the foregoing provisions, no charge shall be made to a Holder hereunder:

Ownership of Notes

(a)

Holder of any Note shall be entitled to the principal, Applicable Premium, if any, and/or interest evidenced by such instruments, respectively, free from all equities or rights of set-off or counterclaim between the Issuer and the original or any intermediate Holder thereof (except in respect of equities of which the Issuer is required to take notice by law) and all Persons may act accordingly and the receipt of any such Holder for any such principal, Applicable Premium, if any, or interest shall be a good discharge to the Trustee, any Registrar and to the Issuer 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, Applicable Premium, if any, and interest from time to time payable in respect thereof may be paid to the order of all or any of such Holders, failing written instructions from them to the contrary, and the receipt of any one of such Holders therefor shall be a valid discharge, to the Trustee, any Registrar and to the Issuer.

(e)

None of the Issuer, 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 Issuer or the Trustee treats, as permitted or required by law, as the owner or the registered holder of such Note, and may transfer the same on the direction of the Person so treated or registered as the holder of the Note, whether named as Trustee or otherwise, as though that Person were the Beneficial Holder of the Note.

Article 5

at least 65% of the aggregate principal amount of Notes (including any Additional Notes) originally issued under this Indenture remains outstanding immediately after the occurrence of such redemption (excluding Notes held by the Issuer and its Subsidiaries); and

(ii)

each such redemption occurs within 180 days of the date of the closing of the related Equity Offering.

(b)

At any time on or prior to March 15, 2015, the Issuer may on any one or more occasions redeem all or a part of the Notes, upon not less than 30 nor more than 60 days' notice, at a Redemption Price equal to 100% of the principal amount of the Notes redeemed, plus the Applicable Premium as of, and accrued and unpaid interest, if any, to the date of redemption.

5.3

Mandatory Redemption

The Issuer is not required to make mandatory redemption or sinking fund payments with respect to the Notes; however, the Issuer may be required to offer to purchase the Notes pursuant to Sections 6.14 and 6.15. The Issuer may at any time and from time to time purchase Notes in the open market or otherwise.

5.4

Places of Payment

The Redemption Price will be payable upon presentation and surrender of Notes called for redemption at any of the places where the principal of such Notes is expressed to be payable and at any other places specified in the notice of redemption.

5.5

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:

(i)

the Notes are listed on any national securities exchange, in compliance with the requirements of the principal national securities exchange on which the Notes are listed; or

(ii)

if the Notes are not listed on any national securities exchange, on a pro rata basis, by lot or by such method as the Trustee deems fair and appropriate.

(b)

Notes or portions of Notes the Trustee selects for redemption shall be in minimum amounts of $1,000 or a multiple of $1,000 in excess thereof. Redemption Notices will be mailed by first class mail at least 30 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 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. Redemption Notices, including without limitation, upon an Equity Offering, may, at the Issuer's discretion, be subject to one or more conditions precedent, including, but not limited to, completion of the related Equity Offering.

(c)

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. In the event that one or more of such Notes becomes subject to redemption in part only, upon surrender of any such Notes for payment of the Redemption Price, together with interest accrued to but excluding the Redemption Date, the Issuer shall execute and the Trustee shall certify and deliver without charge to the Holder thereof or upon the Holder's order one or more new Notes for the unredeemed part of the principal amount of the Note or Notes so surrendered or, with respect to a Global Certificate, the Trustee shall make notations on the Global Certificate of the principal amount thereof so redeemed. Unless the context otherwise requires, the terms "Note" or "Notes" as used in this Article 5 shall be deemed to mean or include any part of the principal amount of any Note which in accordance with the foregoing provisions has become subject to redemption.

5.6

Notice of Redemption

Notice of redemption (the "Redemption Notice") of Notes shall be given to the Holders of the Notes so to be redeemed not more than 60 days nor less than 30 days prior to the date fixed for redemption (the "Redemption Date") in the manner provided in Section 13.2. 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. In addition, unless all the outstanding Notes are to be redeemed, the Redemption Notice shall specify:

(a)

the distinguishing letters and numbers of the Notes which are to be redeemed (or of such thereof as are registered in the name of such Holder);

(b)

in the case of a published notice, the distinguishing letters and numbers of the Notes which are to be redeemed or, if such Notes are selected by terminal digit or other similar system, such particulars as may be sufficient to identify the Notes so selected;

(c)

in the case of Book Entry Only Notes, that the redemption will take place in such manner as may be agreed upon by the Depository, the Trustee and the Issuer; and

(d)

in all cases, the principal amounts of such Notes or, if any such Note is to be redeemed in part only, the principal amount of such part.

Publication of the Redemption Notice shall not be required.

5.7

Notes Due on Redemption Dates

Upon a Redemption Notice having been given as provided in Section 5.6, 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 Redemption Price, together with accrued 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 date of Maturity specified in such Notes, anything therein or herein to the contrary notwithstanding. From and after such Redemption Date, if the monies necessary to redeem such Notes shall have been deposited as provided in Section 5.8 and affidavits or other proof satisfactory to the Trustee as to the publication and/or mailing of such Redemption Notice shall have been lodged with it, interest upon the Notes shall cease. 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 whose decision shall be final and binding upon all parties in interest.

5.8

Deposit of Redemption Monies

(a)

Upon Notes being called for redemption, the Issuer will deposit with the Trustee or any Paying Agent to the order of the Trustee, on or before 11:00 a.m. (Calgary time) on the Business Day immediately prior to the Redemption Date specified in such 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 up to but excluding the Redemption Date, less any tax required by law to be deducted. The Issuer 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 shall pay or cause to be paid, or issue or cause to be issued, to the Holders of such Notes so called for redemption, upon surrender of such Notes, the principal, Applicable Premium (if any) and interest (if any) to which they are respectively entitled on redemption.

(b)

Payment of funds to the Trustee upon redemption of the Notes shall be made by electronic transfer or certified cheque or pursuant to such other arrangements for the provision of funds as may be agreeable between the Issuer and the Trustee in order to effect such payment hereunder. Notwithstanding the foregoing, (i) all payments in excess of $25 million (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 (ii) in the event that payment must be made to the Depository, the Issuer shall remit payment to the Trustee by LVTS. The Trustee shall have no obligation to disburse funds pursuant to this Section 5.8 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.

5.9

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 so to surrender such Holder's Note, or shall not within such time accept payment of the redemption monies payable, or give such receipt therefor, if any, as the Trustee may require, 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, the Note shall thereafter not be considered as outstanding hereunder and the Holder shall have no other right except to receive payment out of the monies so paid and deposited, upon surrender and delivery up of such Holder's Note of the Redemption Price, as the case may be, of such Note, plus any accrued but unpaid interest thereon to but excluding the Redemption Date. In the event that any money required to be deposited hereunder with the Trustee or any Depository or Paying Agent on account of principal, Applicable Premium, if any, or interest, if any, on Notes issued hereunder shall remain so deposited for a period of five years from the Redemption Date, then such monies, together with any accumulated interest thereon, shall at the end of such period be paid over or delivered over by the Trustee or such Depository or Paying Agent to the Issuer on its demand, and thereupon the Trustee shall not be responsible to Holders for any amounts owing to them and subject to applicable law, thereafter the Holder of a Note in respect of which such money was so repaid to the Issuer shall have no rights in respect thereof except to obtain payment of the money due from the Issuer, subject to any limitation period provided by the laws of Alberta. Notwithstanding the foregoing, the Trustee will pay any remaining funds prior to the expiry of five years after the Redemption Date to the Issuer upon receipt from the Issuer, or one of its Subsidiaries, of an unconditional letter of credit from a Canadian chartered bank in an amount equal to or in excess of the amount of the remaining funds. If the remaining funds are paid to the Issuer prior to the expiry of five years after the Redemption Date, and such funds or any portion thereof are claimed after the date of such payment of the remaining funds to the Issuer but prior to five years after the redemption, then the Trustee shall immediately provide to the Issuer written notice of such claim and the Issuer shall promptly deposit with the Trustee funds in the amount necessary to satisfy such claim.

5.10

Cancellation of Notes Redeemed

Subject to the provisions of Sections 5.4 and 5.11 as to Notes redeemed or purchased in part, all Notes redeemed and paid under this Article 5 shall forthwith be delivered to the Trustee and cancelled and no Notes shall be issued in substitution for those redeemed.

5.11

Purchase of Notes for Cancellation

(a)

Provided no Event of Default has occurred and is continuing, the Issuer and its Subsidiaries 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 membership on a recognized stock exchange) or by tender or by contract, at any price. All Notes so purchased may, at the option of the Issuer, be delivered to the Trustee and cancelled and no Notes shall be issued in substitution therefor.

(b)

If, upon an invitation for tenders, more Notes are tendered at the same lowest price that the Issuer is prepared to accept, the Notes to be purchased by the Issuer shall be selected by the Trustee on a pro rata basis or in such other manner as the Issuer 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 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, 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 the Trustee shall certify and deliver such new Note or Notes upon receipt of the Note so surrendered or, with respect to a Global Certificate, the Depository shall make notations on the Global Certificate of the principal amount thereof so purchased.

Article 6
COVENANTS OF THE ISSUER

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

6.1

Payment of Principal, Applicable Premium, and Interest

(b)

The Issuer will pay interest on overdue principal and Applicable Premium, if any, at the then-applicable interest rate on the Notes to the extent lawful, and it will pay interest on overdue instalments of interest at the same rate to the extent lawful.

6.2

Existence

Subject to Article 10, the Issuer will 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, and the corporate, partnership or other legal power, as applicable, of the Issuer and each Restricted Subsidiary; provided that the Issuer will not be required to preserve any such corporate, partnership or other legal existence and corporate, partnership or other legal power if the Board of Directors of the Issuer determines that the preservation thereof is no longer desirable in the conduct of the business of the Issuer, and the Restricted Subsidiaries taken as a whole and that the loss thereof is not disadvantageous in any material respect to the Holders.

6.3

Payment of Taxes and Other Claims

The Issuer will, and will cause each of the Restricted Subsidiaries to, file all tax returns required to be filed in any jurisdiction and to pay and discharge all taxes shown to be due and payable on such returns and all other taxes, assessments, governmental charges, or levies imposed on them or any of their properties, assets, income or franchises, to the extent such taxes and assessments 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 properties or assets of the Issuer or any Restricted Subsidiary; provided that neither the Issuer nor any Restricted Subsidiary need pay any such tax or assessment or claims if (a) the amount, applicability or validity thereof is contested by the Issuer or such Restricted Subsidiary on a timely basis in good faith and in appropriate proceedings, and the Issuer or a Restricted Subsidiary has established adequate reserves therefor in accordance with GAAP on the books of the Issuer or such Restricted Subsidiary or (b) the non-payment of all such taxes and assessments in the aggregate could not reasonably be expected to have a material adverse effect.

6.4

Insurance

The Issuer will at all times keep all of the Issuer's and each Restricted Subsidiary's properties which are of an insurable nature insured with insurers, believed by the Issuer to be responsible, against loss or damage to the extent that property of similar character is usually so insured by Persons similarly situated and owning like properties and conducting like business as the Issuer or such Restricted Subsidiary, as applicable.

6.5

Statement by Officers

(a)

The Issuer will deliver to the Trustee, within 120 days after the end of each of its fiscal years, a brief certificate from the principal executive officer, principal financial officer or principal accounting officer as to his or her knowledge of compliance by the Issuer, and the Restricted Subsidiaries with all conditions and covenants in this Indenture. For purposes of this Section 6.5(a), such compliance shall be determined without regard to any period of grace or requirement of notice in this Indenture.

(b)

When any Default has occurred and is continuing under this Indenture, or if the Trustee or any Holder gives any notice to the Issuer with respect to a claimed Default, the Issuer will deliver to the Trustee by registered or certified mail or by facsimile transmission an Officers' Certificate, specifying such event, notice or other action within 10 Business Days thereafter.

6.6

Provision of Reports and Financial Statements

The Issuer will provide the Trustee, and the Trustee shall deliver to the Holders, a copy of all Financial Statements at the same time as they are required to be filed under Applicable Securities Legislation. Any such obligation to provide such Financial Statements shall continue in the event that the Issuer ceases to be a "reporting issuer" (or its equivalent) as if it had continued to be a "reporting issuer" (or its equivalent), provided that notwithstanding the foregoing, all Financial Statements will be deemed to have been provided to the Trustee and the Holders once filed on the System for Electronic Document Analysis and Retrieval (SEDAR).

6.7

Designation of Restricted and Unrestricted Subsidiaries

The Board of Directors of the Issuer may designate any Restricted Subsidiary 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)

at the time of the designation, the Issuer and its Restricted Subsidiaries could make a Restricted Payment in an amount equal to the Fair Market Value of the Subsidiary so designated in compliance with Section 6.9;

(iii)

at the time of such designation, such Subsidiary has no Indebtedness other than Non-Recourse Debt;

(iv)

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

(v)

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

(b)

Any designation of a Subsidiary of the Issuer as an Unrestricted Subsidiary will be evidenced to the Trustee by filing with the Trustee a Board Resolution of the Issuer giving effect to such designation and an Officers' 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 6.10, the Issuer will be in default of such Section.

(c)

The Board of Directors of the Issuer may designate any Unrestricted Subsidiary to be a Restricted Subsidiary, provided that:

(i)

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

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 6.10, calculated on a pro forma basis as if such designation had occurred at the beginning of the four-quarter reference period;

If a Restricted Subsidiary is designated as an Unrestricted Subsidiary, the aggregate Fair Market Value of all outstanding Investments owned by the Issuer and its Restricted Subsidiaries in the Subsidiary so designated will be deemed to be an Investment made as of the time of the designation. Any such designation shall be permitted only if the Investment would be permitted at that time and if the Restricted Subsidiary otherwise meets the definition of an Unrestricted Subsidiary.

(e)

The Board of Directors of the Issuer may redesignate any Unrestricted Subsidiary to be a Restricted Subsidiary if such redesignation would not cause a Default; provided that 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:

(a)

The Issuer 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 Issuer will not, and will not permit any of its Restricted Subsidiaries to, issue any Disqualified Stock; provided, however, that the Issuer and any of its Restricted Subsidiaries may incur Indebtedness or issue Disqualified Stock immediately after and giving effect thereto (A) if the Fixed Charge Coverage Ratio for the Issuer's most recently ended four full fiscal quarters for which financial statements are publicly available immediately preceding the date on which such additional Indebtedness is incurred or such Disqualified Stock is issued would have been at least 2.25 to 1, 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 had been issued, as the case may be, at the beginning of such four-quarter period and (B) no Default or Event of Default shall have occurred and be continuing.

(i)

the incurrence by the Issuer and its Restricted Subsidiaries of Indebtedness, letters of guarantee, tender cheques and letters of credit under Credit Facilities and the Guarantees thereof; provided that the aggregate principal amount of all Indebtedness of the Issuer and its Restricted Subsidiaries at any one time outstanding under this clause (1) (with letters of guarantee, tender cheques and letters of credit being deemed to have a principal amount equal to the maximum potential liability of the Issuer and its Restricted Subsidiaries thereunder) not to exceed the greater of (A) $300 million, (B) the Borrowing Base and (C) 35% of Adjusted Consolidated Net Tangible Assets, and in the case of (B) and (C) above, 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);

any subsequent issuance or transfer of Equity Interests that results in any such Indebtedness being held by a Person other than the Issuer or a Restricted Subsidiary of the Issuer; and

(B)

any sale or other transfer of any such Indebtedness to a Person that is not either the Issuer or a Restricted Subsidiary of the Issuer;

will be deemed, in each case, to constitute an incurrence of such Indebtedness by the Issuer or such Restricted Subsidiary, as the case may be, that was not permitted by this clause (vi);

(vii)

the incurrence by the Issuer or any Guarantor of Hedging Obligations, provided that such Hedging Obligations were incurred in the ordinary course of business and not for speculative purposes;

(x)

one or more standby letters of credit, Guarantees, completion bonds, performance bonds, bid bonds, appeal bonds or surety bonds or other reimbursement obligations, in each case, issued in the ordinary course of business and not in connection with the borrowing of money or the obtaining of an advance or credit (other than advances or credit for goods and services in the ordinary course of business and on terms and conditions that are customary in the Oil and Gas Business, and other than the extension of credit represented by such letter of credit, Guarantee or completion, performance, bid, appeal or surety bond itself);

(xviii)

a Guarantee by the Issuer or any Restricted Subsidiary in favour of lenders to an Unrestricted Subsidiary provided recourse on such Guarantee is limited to the pledge of Equity Interests in such Unrestricted Subsidiary.

(c)

For purposes of determining compliance with this Section 6.10.

(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 paragraphs (i) through (xviii) above, or is entitled to be incurred pursuant to the first paragraph of this covenant, the Issuer 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 Section 6.10, including by allocation to more than one other type of Indebtedness;

(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; and

(iv)

Indebtedness of any Person existing at the time such Person becomes a Restricted Subsidiary shall be deemed to have been incurred by the Issuer and the Restricted Subsidiary at the time such Person becomes a Restricted Subsidiary.

(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-dominated restriction to be exceeded if calculated at the relevant currency exchange rate in effect on the date of such refinancing, such Canadian dollar-dominated 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 Section 6.10, the maximum amount of Indebtedness that the Issuer may incur pursuant to this Section 6.10 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 Issuer nor any Guarantor will incur any additional Indebtedness (including Permitted Debt) 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.

6.11

Dividend and Other Payment Restrictions Affecting Restricted Subsidiaries

(a)

Issuer 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 Restricted Subsidiary to:

pay dividends or make any other distributions on its Capital Stock to the Issuer or any of its Restricted Subsidiaries or pay any Indebtedness owed to the Issuer 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 Issuer or any of its Restricted Subsidiaries; or

(iii)

sell, lease or transfer any of its properties or assets to the Issuer or any of its Restricted Subsidiaries.

(v)

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

(vi)

purchase money obligations or other similar mortgage financings, in each case, for property acquired in the ordinary course of business that impose restrictions on that property of the nature described in Section 6.11(a)(iii);

(vii)

any agreement (A) for the sale or other disposition of Capital Stock or assets of a Restricted Subsidiary that restricts distributions by that Restricted Subsidiary pending its sale or other disposition, or (B) for the sale of a particular asset or line of business of a Restricted Subsidiary that imposes restrictions on property subject to an agreement of the nature described in Section 6.11(a)(iii);

(viii)

Permitted Refinancing Indebtedness, including any encumbrances or restrictions imposed by any amendments or refinancings of the contracts, instruments and obligations referred to in this covenant, provided that the restrictions contained in the agreements governing such Permitted Refinancing Indebtedness are not materially less favourable to Holders;

(ix)

agreements existing on the Issue Date;

(x)

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

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

(xiii)

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 Issuer and any of its Restricted Subsidiaries to realize the value of, property or assets of the Issuer or any Restricted Subsidiary in any manner material to the Issuer or any Restricted Subsidiary; and

(xiv)

any encumbrance or restriction with respect to an Unrestricted Subsidiary pursuant to or by reason of an agreement that the Unrestricted Subsidiary is a party to entered into before the date on which such Unrestricted Subsidiary became a Restricted 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 Issuer or any other Restricted Subsidiary other than the assets and property so acquired.

6.12

The Issuer 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 the benefit of, any Affiliate (each, an "Affiliate Transaction"), involving aggregate consideration in excess of $1 million for any Affiliate Transactions or series of related Affiliate Transactions unless the Affiliate Transaction is on terms that are no less favourable to the Issuer 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 Issuer or such Restricted Subsidiary in an arm's-length dealing with a Person who is not an Affiliate.

(b)

The following items will be deemed not to be Affiliate Transactions and, therefore, will not be subject to the provisions of Section 6.12(a):

the performance of obligations of the Issuer or any of its Restricted Subsidiaries under the terms of any agreement to which the Issuer or any of its Restricted Subsidiaries is a party as of or on the Issue Date, as these agreements may be amended, modified, supplemented, extended or renewed from time to time; provided, however, that any future amendment, modification, 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, to the Holders than the terms of the agreements in effect on the Issue Date as determined in good faith by the Board of Directors of the Issuer;

(vii)

transactions between the Issuer or any Restricted Subsidiary and any Person, a director of which is also a director of the Issuer or any direct or indirect parent company of the Issuer and such director is the sole cause for such Person to be deemed an Affiliate of the Issuer or any Restricted Subsidiary; provided, however, that such director shall abstain from voting as a director of the Issuer or such direct or indirect parent company, as the case may be, on any matter involving such other Person; and

(viii)

(A) guarantees of performance by the Issuer and its Restricted Subsidiaries of the Issuer's Unrestricted Subsidiaries in the ordinary course of business, except for guarantees of Indebtedness, and (B) pledges of Equity Interests in the Issuer's Unrestricted Subsidiaries for the benefit of lenders to Unrestricted Subsidiaries.

6.13

Issuance of Subsidiary Guarantees

(a)

If any Restricted Subsidiary that is not a Guarantor incurs or guarantees any Indebtedness (other than Indebtedness owing to the Issuer or a Restricted Subsidiary), in each case, in excess of $2.0 million, then the Issuer shall:

(i)

cause such Restricted Subsidiary to execute and deliver to the Trustee a Subsidiary Guarantee substantially in the form contemplated by Article 14 pursuant to which such Restricted Subsidiary shall unconditionally guarantee all of the Issuer's obligations under the Notes and this Indenture on the terms set forth in this Indenture; and

(ii)

deliver to the Trustee an Opinion of Counsel that such Subsidiary Guarantee has been duly authorized, executed and delivered by such Restricted Subsidiary and constitutes a legal, valid, binding and enforceable obligation of such Restricted Subsidiary;

provided, that the foregoing shall not apply to any Restricted Subsidiary acquired or formed by the Issuer for so long as it is not a Wholly Owned Restricted Subsidiary. Thereafter, such Restricted Subsidiary shall be a Guarantor for all purposes of this Indenture.

(b)

The Issuer may cause any other Restricted Subsidiary of the Issuer to issue a Subsidiary Guarantee and become a Guarantor.

(c)

At any time the Indebtedness or guarantee of Indebtedness referred to in Section 6.13(a) is repaid or released without further obligation by such Restricted Subsidiary, such Restricted Subsidiary need no longer be required to be a Guarantor for purposes of Section 6.13(a), and the Trustee shall promptly execute such documents and instruments, as the Issuer or such Restricted Subsidiary may request to evidence the termination of the applicable Subsidiary Guarantee.

6.14

Asset Sales

(a)

The Issuer will not, and will not permit any of its Restricted Subsidiaries to, consummate an Asset Sale unless:

(i)

the Issuer (or the Restricted Subsidiary, as the case may be) receives consideration (including by way of relief from, or by any Person assuming responsibilities for, any liabilities, contingent or otherwise) 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) of the assets, properties or Equity Interests issued or sold or otherwise disposed of;

(ii)

the Fair Market Value is set forth in an Officers' Certificate delivered to the Trustee; and

(iii)

either (x) at least 75% of the consideration received in the Asset Sale by the Issuer or such Restricted Subsidiary is in the form of cash, Cash Equivalents, Liquid Securities or Permitted Assets or (y) the aggregate Fair Market Value of any Designated Non-cash Consideration received by the Issuer or any of its Restricted Subsidiaries in such Asset Sale, taken together with the Fair Market Value at the time of receipt of all other Designated Non-cash Consideration received pursuant to this Section 6.14(a)(iii) less the amount of net proceeds previously realized in cash from prior Designated Non-cash Consideration does not exceed 10% of Adjusted Consolidated Net Tangible Assets measured at the time the determination is made. For purposes of this Section 6.14(a)(iii), each of the following will be deemed to be cash:

(A)

any liabilities, as shown on the Issuer's or such Restricted Subsidiary's most recent balance sheet, of the Issuer or any Restricted Subsidiary (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 Issuer or such Restricted Subsidiary from further liability;

(B)

any securities, notes or other obligations received by the Issuer or any such Restricted Subsidiary from such transferee that are converted within 180 days by the Issuer or such Restricted Subsidiary into cash, to the extent of the cash received in that conversion; and

(C)

accounts receivable of a business retained by the Issuer or any Restricted Subsidiary, as the case may be, following the sale of such business, provided that such accounts receivable are not (1) past due more than 90 days and (2) are collected within 120 days from the date of the invoice creating such accounts receivable.

(b)

Within 365 days after the receipt of any Net Cash Proceeds from an Asset Sale, the Issuer or the applicable Restricted Subsidiary may apply those Net Cash Proceeds for any combination of the following purposes:

(i)

to repay, prepay, redeem, purchase or repurchase (in any case on a permanent basis) Indebtedness of the Issuer or a Restricted Subsidiary that is not Subordinated Indebtedness;

(ii)

to acquire all or substantially all of the assets of, or a majority of the Voting Stock of, another Oil and Gas Business that, in the case of the acquisition of Voting Stock, becomes a Restricted Subsidiary as a result of such acquisition or to acquire additional Capital Stock in any Person that at such time is a Restricted Subsidiary;

(iii)

to make a capital expenditure in respect of its Oil and Gas Business; or

(iv)

to acquire other Permitted Assets.

(c)

Pending the final application of any Net Cash Proceeds in accordance with this Section 6.14, the Issuer may temporarily reduce revolving credit borrowings or otherwise invest the Net Cash Proceeds in any manner that is not prohibited by this Indenture.

(d)

Any Net Cash Proceeds from Asset Sales that are not applied or invested as provided in Sections 6.14(b) or (c) will constitute "Excess Proceeds". On the 366th day after the Asset Sale (or, at the Issuer's option, any earlier date), if the aggregate amount of Excess Proceeds exceeds $20 million, the Issuer will make a pro rata offer (an "Asset Sale Offer") to all Holders and all holders of other Indebtedness that is pari passu 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 any Excess Proceeds remain after consummation of an Asset Sale Offer, the Issuer may use those Excess Proceeds for any purpose not otherwise prohibited by this Indenture. 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 for Notes, the Trustee will select the Notes and such other pari passu Indebtedness to be purchased on a pro rata basis, 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 $1,000 principal amount or multiples of $1,000 in excess thereof). Upon completion of each Asset Sale Offer, the amount of Excess Proceeds will be reset at zero.

(e)

The Issuer will give each Holder written notice of each Asset Sale Offer not less than 30 days and not more than 60 days prior to the date fixed for prepayment thereunder. Each such notice shall specify such date (which shall be a Business Day), the aggregate principal amount of the Notes to be prepaid on such date and the principal amount of each Notes held by such Holder to be prepaid in proportion, as nearly as practicable, to the respective unpaid principal amounts of the Notes being prepaid but not theretofore called for prepayment. Without limiting the foregoing:

(i)

any Holder may decline any offer of prepayment pursuant to this Section 6.14; and

(ii)

the failure of any such Holder to accept or decline any such offer of prepayment shall be deemed to be an election by such Holder to decline such prepayment.

(f)

If the Asset Sale Offer purchase date is on or after an interest payment 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.

(g)

The Issuer 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 the Asset Sale provisions of this Indenture, the Issuer will comply with the Applicable Securities Legislation and regulations and will be deemed not to have breached its obligations under the Asset Sale provisions of this Indenture by virtue of such conflict.

6.15

Purchase of Notes upon a Change of Control

(a)

If a Change of Control occurs, each Holder will have the right to require the Issuer to repurchase all or any part (equal to $1,000 or an integral multiple of $1,000 in excess thereof) of each Holder's Notes pursuant to the offer described below (the "Change of Control Offer"). In the Change of Control Offer, the Issuer will offer a payment (the "Change of Control Payment") in cash equal to 101% of the aggregate principal amount of Notes repurchased plus accrued and unpaid interest, if any, on the Notes repurchased, to the date of purchase (the "Change of Control Payment Date").

(b)

Within 30 days following any Change of Control, the Issuer will notify the Trustee and mail a notice to each Holder describing the transaction or transactions that constitute the Change of Control and offering to repurchase Notes on the Change of Control Payment Date specified in the notice, which date will be no earlier than 30 days and no later than 60 days from the date such notice is mailed, pursuant to the procedures required by this Indenture and described in such notice. The Issuer 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. To the extent that the provisions of any Applicable Securities Legislation conflict with the Change of Control provisions of this Indenture, the Issuer 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 Issuer or its designated agent will, to the extent lawful:

(i)

accept for payment all Notes or portions of Notes 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 Officers' Certificate stating the aggregate principal amount of Notes or portions of Notes being purchased by the Issuer.

(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 Global Certificates, 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 $1,000 or an integral multiple of $1,000 in excess thereof.

(e)

If the Change of Control Payment Date is on or after an interest payment 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 Issuer will publicly announce the results of the Change of Control Offer on or as soon as practicable after the Change of Control Payment Date and in accordance with Applicable Securities Legislation.

(g)

Notwithstanding the preceding paragraphs of this Section 6.15, the Issuer will not be required to make a Change of Control Offer upon a Change of Control and a Holder will not have the right to require the Issuer 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 Issuer and purchases all Notes validly tendered and not withdrawn under such Change of Control Offer or (b) a Redemption Notice has been given pursuant to this Indenture in accordance with Section 5.2, 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 Issuer or a third party may be made in advance of a Change of Control, 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.

(h)

Notwithstanding the foregoing, the Issuer shall not be required to make a Change of Control Offer, as provided above, if, in connection with or in contemplation of any Change of Control, it has made an offer to purchase (an "Alternate Offer") any and all Notes validly tendered at a cash price equal to or higher than the Change of Control Payment and has purchased all Notes properly tendered in accordance with the terms of such Alternate Offer.

(i)

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 Issuer purchases all of the Notes held by such Holders, the Issuer will have the right, upon not less than 30 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 applicable Redemption Date (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).

6.16

SEC Reporting Covenant

The Issuer confirms to the Trustee that its common shares are a class of securities registered pursuant to Section 12 of the U.S. Securities Exchange Act of 0000 (xxx "Xxxxxxxx Xxx"). The Issuer covenants to the Trustee that in the event that the registration of such class of securities shall be terminated by the Issuer in accordance with the Exchange Act, the Issuer shall promptly deliver to the Trustee an Officers' Certificate (in a form provided by the Trustee, acting reasonably) notifying the Trustee of such termination and such other information as the Trustee may reasonably require at the time. The Issuer acknowledges that the Trustee is relying upon the foregoing representation and covenants in order to meet certain SEC obligations with respect to those clients subject to SEC reporting requirements.

6.17

Covenant Suspension

(a)

During any period that (i) the Notes have a rating equal to or higher than "BBB-" by S&P, "Baa3" by Xxxxx'x or "BBB(low)" by DBRS by any two of such three rating agencies ("Investment Grade Ratings") and (ii) no Default has occurred and is continuing (the occurrence of the events described in the foregoing clauses (i) and (ii) being collectively referred to as a "Covenant Suspension Event"), the Issuer and its Restricted Subsidiaries will not be subject to the following provisions:

(i)

Section 6.9;

(ii)

Section 6.10;

(iii)

Section 6.11;

(iv)

Section 6.12;

(v)

Section 6.14; and

(vi)

Paragraph (iv) of Section 10.1.

(collectively, the "Suspended Covenants"); provided, however, that the Issuer and its Restricted Subsidiaries will remain subject to Section 6.15 and Section 6.8.

(b)

In the event that the Issuer and its Restricted Subsidiaries are not subject to the Suspended Covenants for any period of time as a result of Section 6.17(a), and on any subsequent date (the "Reversion Date") one or both of the two applicable rating agencies downgrades the rating assigned to the Notes below that rating set forth in Section 6.17(a), then the Issuer and its Restricted Subsidiaries will thereafter again be subject to the Suspended Covenants (subject to subsequent suspension if the Notes again receive Investment Grade Ratings). The period of time between a Covenant Suspension Event and the related Reversion Date is referred to as the "Suspension Period".

(c)

On each Reversion Date, all Indebtedness incurred, or Disqualified Stock issued, during the Suspension Period will be classified as having been incurred or issued pursuant to Section 6.10(a) or one of the clauses set forth in the definition of "Permitted Debt" (to the extent such Indebtedness or Disqualified Stock would be permitted to be incurred or issued thereunder as of the Reversion Date and after giving effect to Indebtedness incurred or issued prior to the Suspension Period and outstanding on the Reversion Date). To the extent such Indebtedness or Disqualified Stock would not be so permitted to be incurred or issued pursuant to Section 6.10(a) or one of the clauses set forth in the definition of "Permitted Debt," such Indebtedness or Disqualified Stock will be deemed to be permitted. Calculations made after the Reversion Date of the amount available to be made as Restricted Payments under Section 6.9 will be made as though the provisions therein had been in effect since the Initial Issue Date and throughout the Suspension Period. Accordingly, Restricted Payments made during the Suspension Period will reduce the amount available to be made as Restricted Payments under Section 6.9(a). As described above, however, no Default or Event of Default will be deemed to have occurred on the Reversion Date as a result of any actions taken by the Issuer or the Restricted Subsidiaries during the Suspension Period. On and after each Reversion Date, the Issuer and its Subsidiaries will be permitted to consummate the transactions contemplated by any contract entered into during the Suspension Period so long as such contract and such consummation would have been permitted during such Suspension Period.

(d)

For purposes of Section 6.11, on the Reversion Date, any contractual encumbrances or restrictions of the type specified in paragraphs (i), (ii) or (iii) of Section 6.11(a) entered into during the Suspension Period will be deemed to have been in effect on the Initial Issue Date, so that they are permitted under Section 6.11(b)(ix).

(e)

For purposes of Section 6.12, any contract, agreement, loan, advance or Guarantee with or for the benefit of, any Affiliate of the Issuer entered into during the Suspension Period will be deemed to have been in effect as of the Initial Issue Date for purposes of Section 6.12(b)(vii).

(f)

For purposes of Section 6.14, on the Reversion Date, the unutilized Excess Proceeds amount will be reset to zero.

(g)

During a Suspension Period, the Issuer may not designate any of its Subsidiaries as Unrestricted Subsidiaries.

6.18

Waiver of Covenants

The Issuer may omit in any particular instance to comply with any term, provision or condition set forth in this Article 6 if, before or after the time for such compliance, the Holders waive such compliance in such instance with such term, provision or condition, but no such waiver shall extend to or affect such term, provision or condition except to the extent so expressly waived, and, until such waiver shall become effective, the obligations of the Issuer and the duties of the Trustee in respect of any such term, provision or condition shall remain in full force and effect.

Article 7
DEFAULT AND ENFORCEMENT

7.1

Events of Default

Unless otherwise provided in a Supplemental Indenture, an "Event of Default" means any one of the following events:

(a)

default in the payment of any interest on any Note when it becomes due and payable, and continuance of such default for a period of 30 days;

(b)

default in the payment of the principal of (or Applicable Premium, if any on) any Note when due and the continuance of such default for a period of three days;

(c)

failure by the Issuer or any of its Restricted Subsidiaries to comply with the provisions of, Section 6.14, Section 6.15 or Section 10.1;

(d)

(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 (except Non-Recourse Purchase Money Debt) by the Issuer or any of its Restricted Subsidiaries (or the payment of which is guaranteed by the Issuer 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,

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 $25 million, 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;

(f)

failure by the Issuer or any of its Restricted Subsidiaries to pay final judgments aggregating in excess of an amount greater than $15 million in cash (net of amounts covered by insurance or bonded), which judgments are not paid, discharged or stayed for a period of 45 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;

(g)

except as permitted by this Indenture, any Subsidiary Guarantee 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 Person acting on behalf of any such Guarantor, shall deny or disaffirm its obligations under its Subsidiary Guarantee (other than by reason of release of such Guarantor from its Subsidiary Guarantee in accordance with this Indenture);

(h)

an event of default as defined in any instrument under which the Issuer or any Restricted Subsidiary has outstanding Indebtedness, if such Indebtedness results in the foreclosure upon or the exercise of remedies under applicable law or applicable security documents to take ownership of property or assets having a value in excess of $25 million securing such Indebtedness, whether by judicial proceedings or otherwise;

(i)

the Issuer or a Restricted Subsidiary 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; and

(j)

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

(i)

is for relief against the Issuer or any Restricted Subsidiary as debtor in an involuntary case or proceeding;

(ii)

appoints a Custodian of the Issuer or any Restricted Subsidiary or a Custodian for all or substantially all of the assets of the Issuer or any Restricted Subsidiary; or

(iii)

orders the liquidation of the Issuer or any Restricted Subsidiary,

and the order or decree remains unstayed and in effect for 60 consecutive days.

7.2

Acceleration of Maturity; Rescission, Annulment and Waiver

(a)

If an Event of Default (other than as specified in Sections 7.1(i) and 7.1(j)) occurs and is continuing, the Trustee or the Holders of not less than 25% in aggregate principal amount of the outstanding Notes may, and the Trustee at the request of such Holders shall, declare the principal of (and Applicable Premium, if any) and accrued and unpaid interest on, all of the outstanding Notes immediately due and payable and, upon any such declaration, all such amounts will become due and payable immediately. If an Event of Default specified in Sections 7.1(i) and 7.1(j) occurs and is continuing, then the principal (and Applicable Premium, if any), and accrued and unpaid interest on all of the outstanding Notes then will thereupon become and be immediately due and payable without any declaration or other act on the part of the Trustee or any Holder. The Issuer shall deliver to the Trustee, within 10 days after the occurrence thereof, notice of any default or acceleration referred to in Section 7.1(e).

(b)

At any time after a declaration of acceleration, but before a judgment or decree for payment of the money due has been obtained by the Trustee:

(i)

the Holders of a majority in aggregate principal amount of the outstanding Notes, by written notice to the Issuer, the Holders and the Trustee, may rescind and annul such declaration and its consequences if:

(A)

all Events of Default, other than the non-payment of amounts of principal of (and Applicable Premium, if any) or interest on the Notes that have become due solely by such declaration of acceleration, have been cured or waived; and

(B)

such rescission would not conflict with any judgment or decree of a court of competent jurisdiction;

provided that if the Event of Default has occurred by reason of the non-observance or non-performance by the Issuer of any covenant applicable only to one or more series of Notes, then the Holders of a majority of the principal amount of the outstanding Notes of that series shall be entitled to exercise the foregoing power of rescission and the Trustee shall so act and it shall not be necessary to obtain a waiver from the Holders of any other series of Notes; and

(ii)

the Trustee, so long as it has not become bound to declare the principal and interest on the Notes (or any of them) to be due and payable, or to obtain or enforce payment of the same, shall have the power to waive any Event of Default if, in the Trustee's opinion, the same shall have been cured or adequate satisfaction made therefor, and in such event to rescind and annul such declaration and its consequences,

provided that no such rescission shall affect any subsequent Default or impair any right consequent thereon.

(c)

Notwithstanding Section 7.2(a), in the event of a declaration of acceleration in respect of the Notes because an Event of Default specified in Section 7.1(e) shall have occurred and be continuing, such declaration of acceleration shall be automatically annulled if the Indebtedness that is the subject of such Event of Default has been discharged or the holders thereof have rescinded their declaration of acceleration in respect of such Indebtedness, and written notice of such discharge or rescission, as the case may be, shall have been given to the Trustee by the Issuer and countersigned by the holders of such Indebtedness or a trustee, fiduciary or agent for such holders, within 30 days after such declaration of acceleration in respect of the Notes, and no other Event of Default has occurred during such 30 day period which has not been cured or waived during such period.

(d)

The Holders of a majority in aggregate principal amount of the outstanding Notes, by written notice to the Trustee, may on behalf of the Holders of all Notes waive any existing Default or Event of Default and its consequences under this Indenture, except a Default or Event of Default in the payment of interest on, or principal (or Premium, if any) of, any series of Notes; provided that if the Default or Event of Default has occurred by reason of the non-observance or non-performance by the Issuer of any covenant applicable only to one or more series of Notes, then the Holders of a majority of the principal amount of the outstanding Notes of such series shall be entitled to waive such Default or Event of Default and it shall not be necessary to obtain a waiver from the Holders of any other series of Notes.

(e)

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

7.3

Collection of Indebtedness and Suits for Enforcement by Trustee

(a)

The Issuer and each of the Guarantors, if any, 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 Applicable Premium, if any on) any Note at the Maturity thereof,

the Issuer and each Guarantor (if any) will, upon demand of the Trustee, pay to the Trustee for the benefit of the Holders, the whole amount then due and payable on such Notes for principal (and Applicable Premium, if any) and interest, and interest on any overdue principal (and Applicable 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 Issuer or any Guarantor (if any), as the case may be, 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 Issuer, such Guarantor or any other obligor 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 Issuer, such Guarantor or any other obligor upon the Notes, wherever situated.

(c)

If an Event of Default occurs and is continuing, the Trustee may in its discretion proceed to protect and enforce its rights and the rights of the Holders by such appropriate judicial proceedings as the Trustee shall deem most effectual 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.

7.4

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 Issuer and its debts or any other obligor upon the Notes (including the Guarantors, if any), and their debts or the property of the Issuer or of such other obligor or their creditors, the Trustee (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 Issuer for the payment of overdue principal (and Applicable 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 Applicable 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 it for the reasonable compensation, expenses, disbursements and advances of the Trustee, its agents and counsel, and any other amounts due 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.

7.5

Trustee May Enforce Claims Without Possession of Notes

7.6

Application of Monies by Trustee

(a)

Except as herein otherwise expressly provided, any money collected by the Trustee pursuant to this Article 7 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 (or Applicable Premium, if any) or interest, upon presentation of the Notes and the notation thereon of the payment if only partially paid and upon surrender thereof if fully paid:

(i)

first, in payment or in reimbursement to the Trustee of its reasonable compensation, costs, charges, expenses, borrowings, advances or other monies furnished or provided by or at the instance of the Trustee in or about the execution of its trusts under, or otherwise in relation to, this Indenture, with interest thereon as herein provided;

(ii)

second, but subject as hereinafter in this Section 7.6 provided, in payment, rateably and proportionately to the Holders, of the principal of and Applicable Premium (if any) and accrued and unpaid interest and interest on amounts in default on the Notes which shall then be outstanding in the priority of principal first and then Applicable Premium and then accrued and unpaid interest and interest on amounts in default unless otherwise directed by Extraordinary Resolution and in that case in such order or priority as between principal, Applicable Premium (if any) and interest as may be directed by such resolution; and

(iii)

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

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

(b)

The Trustee shall not be bound to apply or make any partial or interim payment of any monies coming into its hands if the amount so received by it, after reserving thereout such amount as the Trustee may think necessary to provide for the payments mentioned in Section 7.6(a), is insufficient to make a distribution of at least 2% of the aggregate principal amount of the outstanding Notes, but it may retain the money so received by it and invest or deposit the same as provided in Section 11.9 until the money or the investments representing the same, with the income derived therefrom, together with any other monies for the time being under its control shall be sufficient for the said purpose or until it shall consider it advisable to apply the same in the manner hereinbefore set forth. The foregoing shall, however, not apply to a final payment or distribution hereunder.

7.7

No Suits by Holders

Except to enforce payment of the principal of, and Applicable Premium (if any) or interest on any Note (after giving effect to any applicable grace period specified therefor in Section 7.1(a) and 7.1(b), no Holder shall have any right to institute any action, suit or proceeding at law or in equity 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 Issuer 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 the Trustee:

(b)

the Holders or any of them shall have furnished to the Trustee, when so requested by the Trustee, sufficient funds and security and indemnity satisfactory to it against the costs, expenses and liabilities to be incurred therein or thereby; and

7.10

Rights and Remedies Cumulative

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.

7.11

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 7 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.

7.12

7.14

Waiver of Stay or Extension Laws

The Issuer 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 Issuer (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 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.

Each Holder and Beneficial Holder, by accepting its interest in the Notes, waives and releases all such claims against, and liability of, such Persons.

For this purpose, Legal Defeasance means that the Issuer and the Guarantors shall be deemed to have paid and discharged the entire Indebtedness represented by the outstanding Notes of such series (including the Guarantees), which shall thereafter be deemed to be "outstanding" only for the purposes of Section 8.7 and the other Sections of this Indenture referred to in paragraphs (i) and (ii) below, and to have satisfied all their other obligations under such Notes and, to the extent applicable to such Notes, the Guarantees and this Indenture (and the Trustee, on demand of and at the expense of the Issuer, shall execute proper instruments acknowledging the same), except for the following provisions which shall survive until otherwise terminated or discharged hereunder:

For this purpose, Covenant Defeasance means that, with respect to the outstanding Notes of any applicable series, the Issuer 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 hereof, but, except as specified above, the remainder of this Indenture and such Notes and Guarantees shall be unaffected thereby. In addition, upon the Issuer's exercise under Section 8.2 of the option applicable to this Section 8.5, subject to the satisfaction of the conditions set forth in Section 8.6, Sections 7.1(c), 7.1(d), 7.1(e), 7.1(f), 7.1(g) and 7.1(h) shall not constitute Events of Default in respect of Notes of such series.

Purpose, Effect and Convention of Meetings

(a)

Subject to Section 12.2(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 9 to consider and resolve whether such consent, waiver, notice, authorization or resolution should be approved by the 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 an Extraordinary Resolution shall be required wherever in this Indenture such consent, waiver, notice, authorization or resolution of the Holders is required to be approved by Extraordinary Resolution or otherwise by Holders of at least 66⅔% in principal amount of the Notes then outstanding.

(b)

At any time and from time to time, the Trustee on behalf of the Issuer may and, on receipt of a Written Order or a Holders' Request and upon being indemnified and funded for the costs thereof to the reasonable satisfaction of the Trustee by the Issuer 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 Issuer or such Holders may themselves convene such meeting and the notice calling such meeting may be signed by such Person as the Issuer or those Holders designate, as applicable. Every such meeting will be held in Calgary, Alberta or such other place as the Trustee may in any case determine or approve.

9.2

Notice of Meetings

At least 21 days notice of any meeting of the Holders shall be given to the Holders of Notes then outstanding in the manner provided in Section 13.2 and a copy of such notice shall be sent by post to the Trustee, unless the meeting has been called by it, and to the Issuer, 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. The accidental omission to give notice of a meeting to any Holder of Notes shall not invalidate any resolution passed at any such meeting. A Holder may waive notice of a meeting either before or after the meeting.

9.3

Chairman

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

9.4

Quorum

Subject to this Indenture, at any meeting of Notes a quorum shall consist of Holders present in Person or by proxy and representing at least 25% of the principal amount of the 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 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.

9.5

Power to Adjourn

The chairman of any meeting at which a quorum of the Holders is present may, with the consent of the Holders of a majority in principal amount of the 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.

9.6

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 Notes of which it is the Holder. A proxy 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 be present in Person or by proxy, they shall vote together in respect of the Notes of which they are joint Holders.

9.7

Poll

A poll will be taken on every resolution and Extraordinary Resolution submitted for approval at a meeting of Holders, in such manner as the Chairman directs, and the results of such polls shall be binding on all Holders. Every resolution, other than an Extraordinary Resolution, will be decided by a majority of the votes cast on the poll for that resolution. An Extraordinary Resolution will require at least 66⅔% of the votes cast on the poll for that resolution to be in the affirmative in order for it be passed.

9.8

Proxies

A Holder may be present and vote at any meeting of Holders by an authorized representative. The Issuer (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 of enabling them to be present and vote at any such meeting by proxy and of 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:

(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 Person signing on behalf of a Holder;

(b)

the deposit of instruments appointing proxies at such place as the Trustee, the Issuer 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, cabled, telegraphed or sent by other electronic means before the meeting to the Issuer 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.

9.9

Persons Entitled to Attend Meetings

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

9.10

Powers Exercisable by Extraordinary Resolution

Subject to Article 12, a meeting of the Holders shall have the following powers exercisable from time to time by Extraordinary Resolution, subject in the case of the matters in paragraphs (g) and (h) to receipt of the prior approval of the exchange, if any, on which any securities of the Issuer are then listed:

(a)

Article 11
CONCERNING THE TRUSTEE

11.1

No Conflict of Interest

The Trustee represents to the Issuer that at the date of execution and delivery by it of this Indenture 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 11.1, such a material conflict of interest exists, or hereafter arises, the validity and enforceability of this Indenture, and the Notes issued hereunder, shall not be affected in any manner whatsoever by reason only that such material conflict of interest exists or arises.

11.2

Replacement of Trustee

(a)

The Trustee may resign its trust and be discharged from all further duties and liabilities hereunder by giving to the Issuer 90 days notice in writing or such shorter notice as the Issuer 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 30 days after ascertaining that such a material conflict of interest exists, either eliminate such material conflict of interest or resign in the manner and with the effect specified in this Section 11.2. 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 Issuer shall forthwith appoint a new Trustee unless a new Trustee has already been appointed by the Holders. Failing such appointment by the Issuer, the retiring Trustee or any Holder may apply to a Judge of the Court of Queen's Bench of Alberta, on such notice as such Judge may direct at the Issuer's expense, for the appointment of a new Trustee but any new Trustee so appointed by the Issuer 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 11.2 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.

(b)

Any company into which the Trustee may be merged or, with or to which it may be consolidated, amalgamated or sold, or any company resulting from any merger, consolidation, sale or amalgamation to which the Trustee shall be a party, 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 Issuer, 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 shall 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 Issuer 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 Trustee, be made, executed, acknowledged and delivered by the Issuer.

11.3

Duties of Trustee

In the exercise of the rights, duties and obligations prescribed or conferred by the terms of this Indenture, the Trustee shall act honestly and in good faith and exercise that degree of care, diligence and skill that a reasonably prudent Trustee would exercise in comparable circumstances. Subject to the foregoing, the Trustee will be liable for its own wilful misconduct, bad faith and gross negligence. 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.

11.4

Reliance Upon Declarations, Opinions, etc.

(a)

In the exercise of its rights, duties and obligations hereunder the Trustee may, if acting in good faith, rely, as to the truth of the statements and accuracy of the opinions expressed therein, upon statutory declarations, opinions, reports or certificates 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 statutory declarations, opinions, reports or certificates and determines that they comply with Section 11.5, 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 rely on an Opinion of Counsel satisfactory to the Trustee notwithstanding that it is delivered by a solicitor or firm which acts as solicitors for the Issuer.

(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 Issuer and its Counsel, to ensure that legends appearing on the Notes comply with regulatory requirements or securities laws of any applicable jurisdiction.

11.5

Evidence and Authority to Trustee, Opinions, etc.

(a)

The Issuer shall furnish to the Trustee evidence of compliance with the conditions precedent provided for in this Indenture relating to any action or step required or permitted to be taken by the Issuer or the Trustee under this Indenture or as a result of any obligation imposed under this Indenture, including without limitation, the certification and delivery of Notes hereunder, the satisfaction and discharge of this Indenture and the taking of any other action to be taken by the Trustee at the request of or on the application of the Issuer, forthwith if and when (a) such evidence is required by any other Section of this Indenture to be furnished to the Trustee in accordance with the terms of this Section 11.5, or (b) the Trustee, in the exercise of its rights and duties under this Indenture, gives the Issuer written notice requiring it to furnish such evidence in relation to any particular action or obligation specified in such notice.

Such evidence shall be, so far as appropriate, in accordance with the immediately preceding paragraph of this Section.

(c)

Each statutory declaration, certificate, opinion or report with respect to compliance with a condition precedent provided for in the Indenture shall include (a) a statement by the Person giving the evidence that he has read and is familiar with those provisions of this Indenture relating to the condition precedent in question, (b) 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, (c) a statement that, in the belief of the Person giving such evidence, he has made such examination or investigation as is necessary to enable him to make the statements or give the opinions contained or expressed therein, and (d) a statement whether in the opinion of such Person the conditions precedent in question have been complied with or satisfied.

(d)

The Issuer shall furnish or cause to be furnished to the Trustee at any time if the Trustee reasonably so requires, its certificate that the Issuer 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 Issuer 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 Issuer or as a result of any obligation imposed by this Indenture.

11.6

Officers' 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 Officers' Certificate.

11.7

Experts, Advisers and Agents

The Trustee may:

(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 expert, whether obtained by the Trustee or by the Issuer, 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 Issuer.

11.8

Trustee May Deal in Notes

Subject to Sections 11.1 and 11.3, the Trustee may, in its personal or other capacity, buy, sell, lend upon and deal in the Notes and generally contract and enter into financial transactions with the Issuer or otherwise, without being liable to account for any profits made thereby.
