The Company shall permit the representatives of each holder of Notes that is an Institutional Investor:

30

Promptly after a request therefor from any holder of Notes that is an Institutional Investor, the Company will provide such holder with a written opinion of counsel (which may be addressed to the Company) relied upon as to any requested information that the Company is prohibited from disclosing to such holder under circumstances described in this Section 7.4.

8. PAYMENT AND PREPAYMENT OF THE NOTES.

8.1. Maturity.

As provided therein, the entire unpaid principal balance of the Notes shall be due and payable on the stated maturity date thereof.

31

8.2. Optional Prepayments with Make-Whole Amount.

The Company may, at its option, upon notice as provided below, prepay at any time all, or from time to time any part of, the Series S Notes, in an amount not less than 10% of the aggregate principal amount of the Series S Notes then outstanding in the case of a partial prepayment, at 100% of the principal amount so prepaid, and the Series S Make-Whole Amount determined for the prepayment date with respect to such principal amount. The Company will give each holder of the Series S Notes written notice of each optional prepayment under this Section 8.2 not less than 30 days and not more than 60 days prior to the date fixed for such prepayment. Each such notice shall specify such date (which shall be a Business Day), the aggregate principal amount of the Series S Notes to be prepaid on such date, the principal amount of each Series S Note held by such holder to be prepaid (determined in accordance with Section 8.4), and the interest to be paid on the prepayment date with respect to such principal amount being prepaid, and shall be accompanied by a certificate of a Senior Financial Officer as to the estimated Series S Make-Whole Amount due in connection with such prepayment (calculated as if the date of such notice were the date of the prepayment), setting forth the details of such computation. Two Business Days prior to such prepayment, the Company shall deliver to each holder of the Series S Notes a certificate of a Senior Financial Officer specifying the calculation of such Series S Make-Whole Amount as of the specified prepayment date.

8.3. Prepayment for Tax Reasons Without Make-Whole.

If at any time as a result of a Change in Tax Law (as defined below) the Company is or becomes obligated to make any Additional Payments (as defined below) in respect of any payment of interest on account of any of the Notes in an aggregate amount for all affected Notes equal to 5% or more of the aggregate amount of such interest payment on account of all of the affected Notes, the Company may give the holders of all affected Notes irrevocable written notice (each, a “Tax Prepayment Notice”) of the prepayment of such affected Notes on a specified prepayment date (which shall be a Business Day not less than 30 days nor more than 60 days after the date of such notice) and the circumstances giving rise to the obligation of the Company to make any Additional Payments and the amount thereof and offering to prepay all of the affected Notes on the date of such prepayment at 100% of the principal amount so prepaid together with interest accrued thereon to the date of such prepayment. Each holder of an affected Note that wishes to accept such prepayment in respect of all or any of the affected Notes held by it shall give written notice to that effect to the Company no more than 20 days after receipt of the Tax Prepayment Notice (each, a “Tax Prepayment Acceptance Notice”). The form of Tax Prepayment Acceptance Notice and a description in reasonable detail of the nature and date of the Change in Tax Law shall accompany the Tax Prepayment Notice. Failure to give a Tax Prepayment Acceptance Notice with respect to any affected Note within such 20 day period shall be deemed to be a rejection of the prepayment of such affected Note or affected Notes held by such holder, and shall operate as a permanent waiver of such holder’s right to receive the Additional Payments arising as a result of the circumstances described in the Tax Prepayment Notice in respect of all future payments of interest on such Note or Notes (but not of such holder’s right to receive any Additional Payments that arise out of circumstances not described in the Tax Prepayment Notice or which exceed the amount of the Additional Payment described in the Tax Prepayment Notice), which waiver shall be binding upon all subsequent transferees of such Notes. The principal amount of all Notes that are the subject of a Tax Prepayment Acceptance Notice together with interest accrued thereon to the date of such prepayment shall become due and payable on such prepayment date.

32

No prepayment of the Notes pursuant to this Section 8.3 shall affect the obligation of the Company to pay Additional Payments in respect of any payment made on or prior to the date of such prepayment. For purposes of this Section 8.3, any holder of more than one affected Note may act separately with respect to each affected Note so held (with the effect that a holder of more than one affected Note may accept such offer with respect to one or more affected Notes so held and reject such offer with respect to one or more other affected Notes so held).

The Company may not offer to prepay or prepay Notes pursuant to this Section 8.3 (a) if a Default or Event of Default then exists, (b) until the Company shall have taken commercially reasonable steps to mitigate the requirement to make the related Additional Payments or (c) if the obligation to make such Additional Payments directly results or resulted from actions taken by the Company or any Subsidiary (other than actions required to be taken under applicable Laws), and any Tax Prepayment Notice given pursuant to this Section 8.3 shall certify to the foregoing and describe such mitigation steps, if any.

For purposes of this Section 8.3: “Additional Payments” means additional amounts required to be paid to a holder of any Note pursuant to Section 13 by reason of a Change in Tax Law; and a “Change in Tax Law” means (individually or collectively with one or more prior changes) (i) an amendment to, or change in, any law, treaty, rule or regulation of Canada after the date of the Closing, or an amendment to, or change in, an official interpretation or application of such law, treaty, rule or regulation after the date of the Closing, which amendment or change is in force and continuing and meets the opinion and certification requirements described below or (ii) in the case of any other jurisdiction that becomes a Taxing Jurisdiction after the date of the Original Note Agreement, an amendment to, or change in, any law, treaty, rule or regulation of such jurisdiction, or an amendment to, or change in, an official interpretation or application of such law, treaty, rule or regulation, in any case after such jurisdiction shall have become a Taxing Jurisdiction, which amendment or change is in force and continuing and meets such opinion and certification requirements. No such amendment or change shall constitute a Change in Tax Law unless the same would in the opinion of the Company (which shall be evidenced by an Officer’s Certificate of the Company and supported by a written opinion of counsel having recognized expertise in the field of taxation in the Taxing Jurisdiction, both of which shall be delivered to all holders of the Notes prior to or concurrently with the Tax Prepayment Notice in respect of such Change in Tax Law) affect the deduction or require the withholding of any Tax imposed by such Taxing Jurisdiction on any payment payable on the Notes.

8.4. Allocation of Partial Prepayments.

In the case of each partial prepayment of the Notes pursuant to Section 8.2, the principal amount of the Notes to be prepaid shall be allocated among all of the Notes at the time outstanding in proportion, as nearly as practicable, to the respective unpaid principal amounts of all Notes not theretofore called for prepayment.

All prepayments pursuant to Sections 8.3 and 8.8 shall be applied as therein provided.

33

8.5. Maturity; Surrender, Etc.

In the case of each prepayment of Notes pursuant to this Section 8, the principal amount of each Note to be prepaid shall mature and become due and payable on the date fixed for such prepayment (which shall be a Business Day), together with interest on such principal amount accrued to such date and the applicable Make-Whole Amount, if any. From and after such date, unless the Company shall fail to pay such principal amount when so due and payable, together with the interest and the applicable Make-Whole Amount, if any, as aforesaid, interest on such principal amount shall cease to accrue. Any Note paid or prepaid in full shall be surrendered to the Company and cancelled and shall not be reissued, and no Note shall be issued in lieu of any prepaid principal amount of any Note.

8.6. Purchase of Notes.

The Company will not and will not permit any Affiliate to purchase, redeem, prepay or otherwise acquire, directly or indirectly, any of the outstanding Notes except upon the payment or prepayment of the Notes in accordance with the terms of this Agreement and the Notes. The Company will promptly cancel all Notes acquired by it or any Affiliate pursuant to any payment or prepayment of Notes pursuant to any provision of this Agreement and no Notes may be issued in substitution or exchange for any such Notes.

8.7. Make-Whole Amount.

The term “Series S Make-Whole Amount” means, with respect to any Series S Note, an amount equal to the excess, if any, of the Discounted Value of the Remaining Scheduled Payments with respect to the Called Principal of such Note over the amount of such Called Principal, provided that none of the Series S Make-Whole Amount may in any event be less than zero. For the purposes of determining the Series S Make-Whole Amount the following terms have the following meanings:

  “Applicable Percentage” means [REDACTED] ([REDACTED] Basis Points).

  “Called Principal” means, with respect to any such Note, the principal of such Note that is to be prepaid pursuant to Section 8.2 or has become or is declared to be immediately due and payable pursuant to Section 12.1, as the context requires.

  “Discounted Value” means, with respect to the Called Principal of any such Note, the amount obtained by discounting all Remaining Scheduled Payments with respect to such Called Principal from their respective scheduled due dates to the Settlement Date with respect to such Called Principal, in accordance with accepted financial practice and at a discount factor (applied on the same periodic basis as that on which interest on the Notes is payable) equal to the Reinvestment Yield with respect to such Called Principal.

  “Reinvestment Yield” means, with respect to the Called Principal of any such Note, the sum of (x) the Applicable Percentage plus (y) the yield to maturity implied by (i) the yields reported as of 10:00 A.M. (New York City time) on the second Business Day preceding the Settlement Date with respect to such Called Principal, on the display designated as “Page PX1” (or such other display as may replace Page PX1) on Bloomberg

34

Financial Markets for the most recently issued actively traded on the run U.S. Treasury securities having a maturity equal to the Remaining Average Life of such Called Principal as of such Settlement Date, or (ii) if such yields are not reported as of such time or the yields reported as of such time are not ascertainable (including by way of interpolation), the Treasury Constant Maturity Series Yields reported, for the latest day for which such yields have been so reported as of the second Business Day preceding the Settlement Date with respect to such Called Principal, in Federal Reserve Statistical Release H.15 (or any comparable successor publication) for U.S. Treasury securities having a constant maturity equal to the Remaining Average Life of such Called Principal as of such Settlement Date. In the case of each determination under clause (i) or clause (ii), as the case may be, of the preceding paragraph, such implied yield will be determined, if necessary, by (a) converting U.S. Treasury ▇▇▇▇ quotations to bond equivalent yields in accordance with accepted financial practice and (b) interpolating linearly between (1) the applicable U.S. Treasury security with the maturity closest to and greater than such Remaining Average Life and (2) the applicable U.S. Treasury security with the maturity closest to and less than such Remaining Average Life. The Reinvestment Yield shall be rounded to the number of decimal places as appears in the interest rate of the applicable Note.

  “Remaining Average Life” means, with respect to any Called Principal, the number of years (calculated to two decimal places) obtained by dividing (i) such Called Principal into (ii) the sum of the products obtained by multiplying (a) the principal component of each Remaining Scheduled Payment with respect to such Called Principal by (b) the number of years (calculated to two decimal places) that will elapse between the Settlement Date with respect to such Called Principal and the Applicable Maturity Date of such Remaining Scheduled Payment.

  “Remaining Scheduled Payments” means, with respect to the Called Principal of any Note, all payments of such Called Principal and interest thereon that would be due after the Settlement Date with respect to such Called Principal if no payment of such Called Principal were made prior to the Applicable Maturity Date, provided that if such Settlement Date is not a date on which interest payments are due to be made under the terms of the Notes, then the amount of the next succeeding scheduled interest payment will be reduced by the amount of interest accrued to such Settlement Date and required to be paid on such Settlement Date pursuant to Section 8.2 or 12.1.

  “Settlement Date” means, with respect to the Called Principal of any Note, the date on which such Called Principal is to be prepaid pursuant to Section 8.2 or has become or is declared to be immediately due and payable pursuant to Section 12.1, as the context requires.

8.8. Prepayment Offer Without Make-Whole on Change in Control.

(c) Acceptance/Rejection. A holder of Notes may accept the offer to prepay made pursuant to this Section 8.8 by causing a notice of such acceptance to be delivered to the Company not later than 15 Business Days after receipt by such holder of the most recent offer of prepayment, but in any event at least 10 Business Days prior to the Proposed Prepayment Date. A failure by a holder of Notes to respond to an offer to prepay made pursuant to this Section 8.8 shall be deemed to constitute a rejection of such offer by such holder.

(d) Prepayment. Prepayment of the Notes to be prepaid pursuant to this Section 8.8 shall be at 100% of the principal amount of such Notes, together with interest on such Notes accrued to the date of prepayment, but without the applicable Make-Whole Amounts or other premium.

Each offer to prepay the Notes pursuant to this Section 8.8 shall be accompanied by a certificate, signed by a Senior Financial Officer of the Company and dated the date of such offer, specifying: (i) the Proposed Prepayment Date; (ii) that such offer is made pursuant to this Section 8.8; (iii) the principal amount of each Note offered to be prepaid;

(iv) the interest that would be due on each Note offered to be prepaid, accrued to the Proposed Prepayment Date; (v) that the conditions of this Section 8.8 have been fulfilled; and (vi) in reasonable detail, the nature and date of the Change in Control.

  (ii) “Equity Interests” means in the case of a corporation, shares of capital stock of any class or series, including warrants, rights, participating interests or options to purchase or otherwise acquire any class or series of capital stock or securities exchangeable for or convertible into any class or series of capital stock, and in the case of any other Person or entity shall mean any class or series of partnership interests, units, membership interests or like interests constituting equity, and in the case of each of the foregoing, any part or portion thereof or participation in any of the foregoing.

The Company may designate any Unrestricted Subsidiary as a Restricted Subsidiary and may designate any Restricted Subsidiary as an Unrestricted Subsidiary by providing to the holders of Notes a Notice of Designation in the form attached hereto as Exhibit 9.9; provided that:

38

(a) no Default or Event of Default (including as determined by a Current Financial Covenant Testing) will exist immediately following such designation, and the Company shall have provided an Officer’s Certificate to that effect at the time it provides such notice;

(b) in the case of the designation of an Unrestricted Subsidiary as a Restricted Subsidiary and after giving effect thereto, all existing Liens of such Restricted Subsidiary so designated shall be permitted within the applicable limitations of Section 10.4, notwithstanding that any such Lien may have existed as of the date of the Original Note Agreement;

(d) if required by Section 9.10, each Restricted Subsidiary shall forthwith become a Subsidiary Guarantor;

(e) any Restricted Subsidiary that was previously designated as an Unrestricted Subsidiary shall not be redesignated as a Restricted Subsidiary if a Default or Event of Default (including as determined by a Current Financial Covenant Testing) exists immediately prior to such designation; and

9.10. Subsidiary Guarantees.

The Company will cause each Subsidiary of the Company (other than any Subsidiary which already is a Subsidiary Guarantor) that hereafter becomes a borrower or a guarantor under the Bank Facility, concurrently therewith to enter into and become a party to a Subsidiary Guarantee, and within three Business Days thereafter, to deliver to each holder of a Note the following:

(a) the Subsidiary Guarantee and the Security Documents (as provided in Section 9.16), or applicable joinders thereto;

If any such Subsidiary Guarantor subsequently ceases to be a borrower or a guarantor under the Bank Facility (other than as a result of the Bank Facility reaching its scheduled maturity date without renewal and provided that, on the date such Subsidiary Guarantor ceases to be a borrower or guarantor under the Bank Facility, the Liens encumbering assets of such Subsidiary Guarantor created by the Security Documents have been released and discharged in accordance with Section 9.16(g)), then the Company may require the holders of Notes to release such Subsidiary from its Subsidiary Guarantee and any Security Document to which it is a party upon giving 5 Business Days written notice thereof to the holders of Notes together with confirmation of the foregoing reasonably satisfactory to the holders of Notes, whereupon such Subsidiary shall cease to be a Subsidiary Guarantor hereunder and any Lien granted by it pursuant to the Security Documents shall be released and discharged (and the Company may take any additional steps and actions it deems necessary to discharge corresponding Lien registrations and filings), provided that at the time of such notice and the effective date of such release as provided below, and immediately after giving effect thereto, and to such Subsidiary ceasing to be a Subsidiary Guarantor, no Default or Event of Default (including as determined by a Current Financial Covenant Testing) exists or would exist, and the Company shall have provided an Officer’s Certificate to such effect at the time it provides such notice, with the information (including detailed calculations) required in order to establish same. Upon compliance with the requirements of the preceding sentence, the Subsidiary Guarantee of such Subsidiary shall be deemed to be released and terminated, and any Lien granted by it pursuant to the Security Documents shall be deemed to be released and discharged, as at the expiry of such 5 Business Day period (unless sooner terminated by all the holders of Notes).

9.11. Subordination Agreements.

The Company will cause each Affiliate (a “Subordinating Person”) that hereafter subordinates any obligations owed to such Subordinating Person by the Company or any Subsidiary Guarantor in favor of any obligations owed by the Company or any Subsidiary Guarantor under the Bank Facility, to concurrently therewith enter into a subordination agreement on the same terms in favor of the holders of the Notes, and within three Business Days thereafter, the Company shall deliver to each holder of a Note the following:

9.16. Security Prior to Security Release Date.

(a) From and after May 22, 2015 until the Security Release Date, the Company will provide (or cause to be provided) to the Collateral Agent, for and on behalf of, inter alios, the holders of Notes, as continuing security for the Obligations, a debenture from the Company and the Subsidiary Guarantors creating a Lien in favor of the Collateral Agent in respect of all their present and after-acquired property, assets and undertaking and a floating charge over all present and future owned real property (the “Security”).

(b) The Security shall be in form and substance satisfactory to the Requisite Secured Parties in their sole discretion. The Requisite Secured Parties, acting reasonably, may require that any Security Document be governed by the Laws of the jurisdiction in which the property in which a Lien is created pursuant to such Security Document is located. The Security Documents shall be registered by the Company or the Subsidiary Guarantors, as applicable, where necessary or desirable to record and perfect the Liens created thereby, as determined by the Requisite Secured Parties in their sole discretion, and if the Company or any Subsidiary Guarantor does not so register the Security Documents as requested, any holder of Notes may do the same (the cost of which will be borne by the Company).

(c) The Company will cause to be delivered to the Collateral Agent and each holder of Notes the results of all applicable searches in respect of the Company and the Subsidiary Guarantors in the applicable jurisdictions as well as the opinions of solicitors for the Company and the Subsidiary Guarantors regarding their corporate status, the due authorization, execution and delivery of the Security Documents provided by them, the creation of the Liens pursuant to the Security Documents and all registrations in respect of the Security Documents, and the validity and enforceability of such Security Documents; all such opinions to be in form and substance satisfactory to the Required Holders and their counsel.

(d) The Company will and will cause each Subsidiary Guarantor to execute any and all further documents, financing statements, agreements and instruments, and take all further action (including filing Personal Property Security Act (Alberta) and Land Titles Act (Alberta) and other financing statements, registering the Security at any land titles or land registry offices or under the Mines and Mineral Act (Alberta) or any similar registry in any other applicable jurisdiction, and filing any other notices, mortgages, deeds of trust and caveats (or the equivalent statements in any other jurisdiction)) that may from time to time be required under applicable Laws, or that the Collateral Agent or the Requisite Secured Parties may reasonably request, in order to effectuate the transactions contemplated by the Financing Agreements and in order to grant, preserve, protect and perfect the validity, enforceability and priority of the Liens created or intended to be created by the Security Documents. For the avoidance of doubt, the Requisite Secured Parties and the Collateral Agent shall have the right to require the Company and each Subsidiary Guarantor to amend or supplement any Security Documents or related registrations to the extent necessary to reflect any changes in applicable Laws (or the interpretation thereof) or any directives, rules or procedures related thereto, whether arising as a result of statutory amendments, court decisions or otherwise, and whether occurring prior to or subsequent to the date hereof.

42

(e) Notwithstanding the foregoing, neither the Company nor any Subsidiary Guarantor shall be required (and neither the holders of Notes nor the Collateral Agent shall be entitled) to effect any fixed charge registrations against any real property (including for certainty, registering the Security at any land titles or land registry offices or under the Mines and Mineral Act (Alberta) or any similar registry in any other applicable jurisdiction unless an Event of Default has occurred and is continuing except as otherwise set forth in the Intercreditor Agreement). After an Event of Default has occurred and is continuing, from time to time upon the request of the Collateral Agent or the Requisite Secured Parties, within ten Business Days of such request, the Company shall, at the Company’s sole cost and expense, execute and deliver, and shall cause each Subsidiary Guarantor to execute and deliver, such additional or supplemental Security Documents as the Collateral Agent or the Requisite Secured Parties may reasonably request in order to ensure that all Collateral held by the Company and the Subsidiary Guarantors is validly subjected to first fixed charge Liens in favor of the Collateral Agent for the benefit of the holders of Notes, subject only to Permitted Encumbrances, and in connection therewith shall provide to the Collateral Agent a land schedule in form satisfactory to the Collateral Agent and the Requisite Secured Parties detailing all Collateral then held by the Company and the Subsidiary Guarantor (which shall include legal descriptions, crown lease numbers and issue dates, reserve numbers, zone restrictions, names of freehold lessors, and the interest of the Company and each Subsidiary Guarantor therein before and after payout of working interests and all royalties and burdens). The Company will pay all reasonable costs and expenses incurred by the Collateral Agent or any holder in connection with the preparation, execution, delivery and registration of all documents, agreements, instruments and registrations necessary or advisable to implement the provisions of this Section 9.16(e).

(f) The Company and its Subsidiary Guarantors shall not be discharged from the Subsidiary Guarantee except in accordance with the last paragraph of Section 9.10 or by a written release signed by all holders of Notes and the Liens in respect of the Security shall not be discharged and released except (A) in accordance with Section 9.16(g) and the Intercreditor Agreement or (B) in connection with a Disposition of assets permitted by Section 10.11, to the extent, but only to the extent, that such Liens encumber assets subject to such Disposition.

(g) The Liens created or intended to be created by the Security Documents in accordance with this Section 9.16 shall be fully released and discharged (and the Company may take any additional steps and actions it deems necessary to discharge any corresponding Liens registrations and filings), and the Security Documents shall be terminated and be of no further force and effect, upon the date when both of the following are satisfied (the “Security Release Date”):

  (i) a date on which the Notes and the other Outstanding Notes have been paid in full, in cash; and

  (ii) a date on which no Default or Event of Default has occurred and is continuing on such date and the Collateral subject to the Intercreditor Agreement is concurrently released by the lenders under the Bank Facility and the noteholders under each Other Note Agreement and the Intercreditor Agreement is concurrently terminated.

(h) Nothing contained herein or in the Security Documents now held or hereafter acquired by the holders, nor any act or omission of the Collateral Agent or the holders with respect to any such Security Documents, will in any way prejudice or affect the rights, remedies or powers of the holders with respect to any other Financing Agreement at any time held by them.

43

9.17. Material Adverse Claims.

The Company will, and will cause each Subsidiary Guarantor to, do all things necessary to defend and protect their property from all material adverse claims, and to maintain their property free therefrom, except for Permitted Encumbrances, where the failure to do so (a) in the opinion of the Required Holders and/or Collateral Agent, acting reasonably, threatens the actual or intended priority or validity of the Security Documents and the Liens created therein, as provided herein, in the Security Documents and in the Intercreditor Agreement, or (b) has had or would reasonably be expected to have a Material Adverse Effect.

9.18. Protection of Security.

The Company will, and will cause each Subsidiary Guarantor to, do all things reasonably requested by the Required Holders or the Collateral Agent to protect and maintain the validity and enforceability of the Security Documents and the first-ranking priority thereof, as contemplated herein and in the Intercreditor Agreement, in relation to other Persons.

9.19. [Reserved].

9.20. Hedging Plan.

The Company will comply with the Hedging Plan, as such plan may be amended from time to time with the approval of the Company’s board of directors (whether by amendment of such plan or the hedging policy adopted by the Company’s board of directors) and in a manner consistent with prudent management of risk related to volatility in prices of Petroleum Substances.

9.21. Most Favored Lender.

If, at any time after the Effective Date, the Bank Facility or any other agreement related to the Bank Facility is amended, supplemented, revised or modified in any way to include: (a) any one or more new covenants or events of default that are not provided for in the Financing Agreements taking into account the different relevant circumstance between the Bank Facility and the Financing Agreements, or (b) any one or more new covenants or events of default that are more restrictive, taken as a whole, than the same or similar covenants or events of default provided in this Agreement or the other Financing Agreements taking into account the different relevant circumstances between the Bank Facility and the Financing Agreements, then: (i) the Obsidian Parties shall promptly, and in any event within ten (10) days after entering into any such additional or more restrictive covenants or events of default so advise the holders of Notes in writing and (ii) such additional or more restrictive covenants or events of default shall be incorporated by reference in this Agreement as if set forth fully herein, mutatis mutandis. Thereafter, upon the request of the Required Holders, the Required Holders and the Company shall enter into an amendment to this Agreement evidencing the incorporation of such additional or more restrictive covenants or events of default, it being agreed that any failure to make such request or to enter into any such amendment shall in no way qualify or limit the incorporation by reference described in clause (ii) of the immediately preceding sentence.

44

Notwithstanding the foregoing, provisions of the Bank Facility (or any document in respect thereof) that impose a limit on the amount of Indebtedness that may be incurred under this Agreement, shall not be subject to the requirements of the first paragraph of this Section 9.21.

If, prior to a Consensual Transaction, there is any increase in the margin applicable to any one or more loans outstanding under the Bank Facility above the margin in effect on the Effective Date or any fee or other compensation is paid or payable to the Lenders in connection with (x) an extension of the Revolving Period (as defined in the Bank Facility as in effect on the Effective Date) or (y) deferring a redetermination of the Borrowing Base (as defined in the Bank Facility as in effect on the Effective Date) or refraining from exercising a right to redetermine the Borrowing Base, then (a) in the case of an increase in such margin, the interest rate on the Notes shall increase by the same number of Basis Points as such margin has increased for the same period that such increase in the margin shall exist, and (b) in the case of any fee or other compensation, the equivalent of such fee or other compensation shall be given to the holders of Notes promptly, and in any event not more than five (5) Business Days after such consideration is given to the Lenders; provided, however, that fees payable to the Lenders under the Seventh Amending Agreement to the Bank Facility shall not be subject to the requirements of this Section 9.21.

12. REMEDIES ON DEFAULT, ETC.

12.1. Acceleration.

(a) If an Event of Default with respect to the Company described in Sections 11(g), 11(h) or 11(i) (other than an Event of Default described in clause (i) of Section 11(g) or described in clause (vi) of Section 11(g) by virtue of the fact that such clause encompasses clause (i) of Section 11(g)) has occurred, all the Notes then outstanding shall automatically become immediately due and payable.

51

(b) If any other Event of Default has occurred and is continuing, the Required Holders may at any time at their option, by notice or notices to the Company, declare all the Notes then outstanding to be immediately due and payable.

(c) If any Event of Default described in Section 11(a) or 11(b) has occurred and is continuing, any holder or holders of Notes at the time outstanding affected by such Event of Default may at any time, at its or their option, by notice or notices to the Company, declare all the Notes held by it or them to be immediately due and payable.

Upon any Notes becoming due and payable under this Section 12.1, whether automatically or by declaration, such Notes will forthwith mature and the entire unpaid principal amount of such Notes, plus (x) all accrued and unpaid interest thereon (including, without limitation, interest accrued thereon at the applicable rate specified in the Notes during an Event of Default) and (y) the Make-Whole Amount or the Protective Claim Amount, as applicable (as specified in the next succeeding sentence of this paragraph), determined in respect of such principal amount (to the full extent permitted by applicable Laws), shall all be immediately due and payable, in each and every case without presentment, demand, protest or further notice, all of which are hereby waived. The Company acknowledges, and the parties hereto agree, that (i) the Make-Whole Amount shall be payable if the Notes are payable pursuant to this Section 12.1 in any circumstance where a Consensual Transaction has occurred and (ii) the Protective Claim Amount shall be payable if the Notes are payable pursuant to this Section 12.1 prior to the occurrence of a Consensual Transaction. The Company acknowledges, and the parties hereto agree, that each holder of a Note has the right to maintain its investment in the Notes free from repayment by the Company (except as herein specifically provided for) and that the provision for payment of a Make-Whole Amount or Protective Claim Amount, as the case may be, by the Company in the event that the Notes are repaid as provided in the preceding sentence is intended to provide compensation for the deprivation of such right under such circumstances.

“Crystallized Make-Whole Amount” means $[REDACTED] in the aggregate for all Series S Notes and, in respect of any Series S Note, means a ratable share of such amount based on the principal amount of such Series S Note as a percentage of the aggregate principal amount of all Series S Notes, in each case at the time the Crystallized Make-Whole Amount is payable.

“Protective Claim Amount” means, in respect of any Series S Notes, the sum of (a) the Crystallized Make-Whole Amount in respect of such Series S Note plus (b) interest at 2% per annum on such Crystallized Make-Whole Amount and on the principal amount of such Series S Note accrued during the period from and including March 13, 2020 to but excluding the date of payment in full of such Protective Claim Amount and principal.

12.2. Other Remedies.

If any Default or Event of Default has occurred and is continuing, and irrespective of whether any Notes have become or have been declared immediately due and payable under Section 12.1, the holder of any Note at the time outstanding may proceed to protect and enforce the rights of such holder by an action at law, suit in equity or other appropriate proceeding, whether for the specific performance of any agreement contained herein or in any Note, or for an injunction against a violation of any of the terms hereof or thereof, or in aid of the exercise of any power granted hereby or thereby or by law or otherwise.

12.3. Rescission.

At any time after any Notes have been declared due and payable pursuant to Section 12.1(b) or 12.1(c), the Required Holders, by written notice to the Company, may rescind and annul any such declaration and its consequences if (a) the Company has paid all overdue interest on the Notes, all principal of and Make-Whole Amount, if any, on any Notes that are due and payable and are unpaid other than by reason of such declaration, and all interest on such overdue principal and Make-Whole Amount, if any, and (to the extent permitted by applicable Laws) any overdue interest in respect of the Notes, at the applicable rate specified in the Notes during an Event of Default, (b) neither the Company nor any other Person shall have paid any amounts that have become due solely by reason of such declaration, (c) all Events of Default and Defaults, other than non-payment of amounts that have become due solely by reason of such declaration, have been cured or have been waived pursuant to Section 18, and (d) no judgment or decree has been entered for the payment of any monies due pursuant hereto or to the Notes. No rescission and annulment under this Section 12.3 will extend to or affect any subsequent Event of Default or Default or impair any right consequent thereon.

12.4. No Waivers or Election of Remedies, Expenses, Etc.

No course of dealing and no delay on the part of any holder of any Note in exercising any right, power or remedy shall operate as a waiver thereof or otherwise prejudice such holder’s rights, powers or remedies. No right, power or remedy conferred by this Agreement or by any Note upon any holder thereof shall be exclusive of any other right, power or remedy referred to herein or therein or now or hereafter available at law, in equity, by statute or otherwise. Without limiting the obligations of the Company under Section 16, the Company will pay to the holder of each Note on demand such further amount as shall be sufficient to cover all costs and expenses of such holder incurred in any enforcement or collection under this Section 12, including, without limitation, reasonable attorneys’ fees, expenses and disbursements.

13. TAX INDEMNIFICATION.

All payments whatsoever under the Financing Agreements will be made by the Company and the Subsidiary Guarantors free and clear of, and without liability for withholding or deduction for or on account of, any present or future Taxes of whatever nature imposed or levied by or on behalf of any jurisdiction (or any political subdivision or taxing authority of or in such jurisdiction) (hereinafter a “Taxing Jurisdiction”), unless the withholding or deduction of such Tax is compelled by law.

If any deduction or withholding for any Tax of a Taxing Jurisdiction shall at any time be required in respect of any amounts to be paid by the Company or the Subsidiary Guarantors under the Financing Agreements, the Company or the Subsidiary Guarantors, as applicable, will pay to the relevant Taxing Jurisdiction the full amount required to be withheld, deducted or otherwise paid before penalties attach thereto or interest accrues thereon and pay to each holder of a Note such additional amounts as may be necessary in order that the net amounts paid to such

53

holder pursuant to the terms of the Financing Agreements after such deduction, withholding or payment (including, without limitation, any required deduction or withholding of Tax on or with respect to such additional amount), shall be not less than the amounts then due and payable to such holder under the terms of the Financing Agreements before the assessment of such Tax, provided that no payment of any additional amounts shall be required to be made for or on account of:

(a) any Tax that would not have been imposed but for the existence of any present or former connection between such holder (or a fiduciary, settlor, beneficiary, member of, shareholder of, or possessor of a power over, such holder, if such holder is an estate, trust, partnership or corporation or any Person other than the holder to whom the Notes or any amount payable thereon is attributable for the purposes of such Tax) and the Taxing Jurisdiction, other than the mere holding of the relevant Note or the receipt of payments thereunder or in respect thereof, including, without limitation, such holder (or such other Person described in the above parenthetical) being or having been a citizen or resident thereof, or being or having been present or engaged in trade or business therein or having or having had an establishment, office, fixed base or branch therein, provided that this exclusion shall not apply with respect to a Tax that would not have been imposed but for the Company or the Subsidiary Guarantor, after the date of the Original Note Agreement, opening an office in, moving an office to, reincorporating in, or changing the Taxing Jurisdiction from or through which payments on account of the Financing Agreements are made to, the Taxing Jurisdiction imposing the relevant Tax;

(b) any Tax that would not have been imposed but for the delay or failure by such holder (following a written request by the Company) in the filing with the relevant Taxing Jurisdiction of Forms (as defined below) that are required to be filed by such holder to avoid or reduce such Taxes (including for such purpose any refilings or renewals of filings that may from time to time be required by the relevant Taxing Jurisdiction), provided that the filing of such Forms would not (in such holder’s reasonable judgment) impose any unreasonable burden (in time, resources or otherwise) on such holder or result in any confidential or proprietary income tax return information being revealed, either directly or indirectly, to any Person and such delay or failure could have been lawfully avoided by such holder, and provided further that such holder shall be deemed to have satisfied the requirements of this clause (b) upon the good faith completion and submission of such Forms (including refilings or renewals of filings) as may be specified in a written request of the Company no later than 60 days after receipt by such holder of such written request (accompanied by copies of such Forms and related instructions, if any, all in the English language or with an English translation thereof);

(c) any amount in excess of the amount of tax that would be payable if the holder was a resident of the United States of America for the purpose of the Canada-U.S. Income Tax Convention (1980), as amended;

(d) any Tax that would not have been imposed but for the holder not dealing at arm’s length with the Company for the purposes of the Tax Act; or

(e) any combination of clauses (a), (b), (c) or (d) above.

54

If as a result of any payment by the Company or a Subsidiary Guarantor under the Financing Agreements, whether in respect of principal, Make-Whole Amounts (if any), Protective Claim Amount, interest, interest on overdue interest, fees or other payment obligations, any holder of a Note is required to pay tax under Part XIII of the Tax Act, then the Company or applicable Subsidiary Guarantor will, upon demand by such holder of any Note, indemnify the holder for the payment of any such amount, together with any interest, penalties and expenses in connection therewith, and for any Taxes on such indemnity payment provided that no indemnification payment shall be required to be made in respect of a Tax described in clauses (a), (b), (c), (d) or (e) of the previous paragraph. All amounts payable under this paragraph shall be payable by the Company or applicable Subsidiary Guarantor on demand, shall, if paid in respect of interest, be a payment of additional interest, and shall bear interest at the Default Rate, calculated from the date demanded by such holder to the date paid by the Company or applicable Subsidiary Guarantor.

By acceptance of any Note, the holder of such Note agrees, subject to the limitations of clause (b) above, that it will from time to time with reasonable promptness (x) duly complete and deliver to or as reasonably directed by the Company all such forms, certificates, documents and returns provided to such holder by the Company (collectively, together with instructions for completing the same, “Forms”) required to be filed by or on behalf of such holder in order to avoid or reduce any such Tax pursuant to the provisions of an applicable statute, regulation or administrative practice of the relevant Taxing Jurisdiction or of an applicable tax treaty between the United States and such Taxing Jurisdiction, and (y) provide the Company with such information with respect to such holder as the Company may reasonably request in order to complete any such Forms, provided that nothing in this Section 13 shall require any holder to provide information with respect to any such Form or otherwise if in the opinion of such holder such Form or disclosure of information would involve the disclosure of tax return or other information that is confidential or proprietary to such holder, and provided further that each such holder shall be deemed to have complied with its obligation under this paragraph with respect to any Form if such Form shall have been duly completed and delivered by such holder to the Company or mailed to the appropriate taxing authority, whichever is applicable, within 60 days following a written request of the Company (which request shall be accompanied by copies of such Form and English translations of any such Form not in the English language) and, in the case of a transfer of any Note, at least 90 days prior to the relevant interest payment date.

If any payment is made by the Company to or for the account of the holder of any Note after deduction for or on account of any Taxes, and increased payments are made by the Company pursuant to this Section 13, then, if such holder at its sole discretion determines that it has received or been granted a refund of such Taxes, such holder shall, to the extent that it can do so without prejudice to the retention of the amount of such refund, reimburse to the Company such amount as such holder shall, in its sole discretion, determine to be attributable to the relevant Taxes or deduction or withholding. Nothing herein contained shall interfere with the right of the holder of any Note to arrange its tax affairs in whatever manner it thinks fit and, in particular, no holder of any Note shall be under any obligation to claim relief from its corporate profits or similar tax liability in respect of such Tax in priority to any other claims, reliefs, credits or deductions available to it or (other than as set forth in clause (b) above) oblige any holder of any Note to disclose any information relating to its tax affairs or any computations in respect thereof.

55

The Company will furnish the holders of Notes with the original tax receipt issued to the Company for all amounts paid as Tax in respect of any amount paid under a Financing Agreement within the time period specified under the relevant Law (or if such original tax receipt is not available or must legally be kept in the possession of the Company, a duly certified copy of the original tax receipt or any other reasonably satisfactory evidence of payment), together with such other documentary evidence with respect to such payments as may be reasonably requested from time to time by any holder of a Note.

If the Company is required by any applicable Laws, as modified by the practice of the taxation or other authority of any relevant Taxing Jurisdiction, to make any deduction or withholding of any Tax in respect of which the Company would be required to pay any additional amount under this Section 13, but for any reason does not make such deduction or withholding with the result that a liability in respect of such Tax is assessed directly against the holder of any Note, and such holder pays such liability, then the Company will promptly reimburse such holder for such payment (including any related interest or penalties to the extent such interest or penalties arise by virtue of a default or delay by the Company) upon demand by such holder accompanied by an official receipt (or a duly certified copy thereof) issued by the taxation or other authority of the relevant Taxing Jurisdiction.

If the Company makes payment to or for the account of any holder of a Note and such holder is entitled to a refund of the Tax to which such payment is attributable upon the making of a filing (other than a Form described above), then such holder shall, as soon as practicable after receiving written request from the Company (which shall specify in reasonable detail and supply the refund forms to be filed) use reasonable efforts to complete and deliver such refund forms to or as directed by the Company, subject, however, to the same limitations with respect to Forms as are set forth above.

The obligations of the Company under this Section 13 shall survive the payment or transfer of any Note and the provisions of this Section 13 shall also apply to successive transferees of the Notes.

14. REGISTRATION; EXCHANGE; SUBSTITUTION OF NOTES.

14.1. Registration of Notes.

The Company shall keep at its principal executive office a register for the registration and registration of transfers of Notes. The name and address of each holder of one or more Notes, each transfer thereof and the name and address of each transferee of one or more Notes shall be registered in such register. If any holder of one or more Notes is a nominee, then (a) the name and address of the beneficial owner of such Note or Notes shall also be registered in such register as an owner and holder thereof and (b) at any such beneficial owner’s option, either such beneficial owner or its nominee may execute any amendment, waiver or consent pursuant to this Agreement. Prior to due presentment for registration of transfer, the Person in whose name any Note shall be registered shall be deemed and treated as the owner and holder thereof for all purposes hereof, and the Company shall not be affected by any notice or knowledge to the contrary. The Company shall give to any holder of a Note that is an Institutional Investor promptly upon request therefor, a complete and correct copy of the names and addresses of all registered holders of Notes.

56

14.2. Transfer and Exchange of Notes.

Upon surrender of any Note to the Company at the address and to the attention of the designated officer (all as specified in Section 19) for registration of transfer or exchange (and in the case of a surrender for registration of transfer accompanied by a written instrument of transfer duly executed by the registered holder of such Note or such holder’s attorney duly authorized in writing and accompanied by the relevant name, address and other details for notices of each transferee of such Note or part thereof) within ten Business Days thereafter the Company shall execute and deliver, at the Company’s expense (except as provided below), one or more new Notes (as requested by the holder thereof) in exchange therefor, in an aggregate principal amount equal to the unpaid principal amount of the surrendered Note of the same series. Each such new Note shall be payable to such Person as such holder may request and shall be substantially in the form of Exhibit 1S. Each such new Note shall be dated and bear interest from the date to which interest shall have been paid on the surrendered Note or dated the date of the surrendered Note if no interest shall have been paid thereon. The Company may require payment of a sum sufficient to cover any stamp tax or governmental charge imposed in respect of any such transfer of Notes. Notes shall not be transferred in denominations of less than U.S.$250,000, provided that (i) a Note originally issued in an amount less than U.S.$250,000, may be transferred in such original amount, and (ii) if necessary to enable the registration of transfer by a holder of its entire holding of Notes, one Note may be in a denomination of less than U.S.$250,000. Any transferee, by its acceptance of a Note registered in its name (or the name of its nominee), shall be deemed to have made the representation set forth in Section 6.2.

14.3. Replacement of Notes.

Upon receipt by the Company at the address and to the attention of the designated officer (all as specified in Section 19(c)) of evidence reasonably satisfactory to it of the ownership of and the loss, theft, destruction or mutilation of any Note (which evidence shall be, in the case of an Institutional Investor, notice from such Institutional Investor of such ownership and such loss, theft, destruction or mutilation), and

(a) in the case of loss, theft or destruction, of indemnity reasonably satisfactory to it (provided that if the holder of such Note is, or is a nominee for, an original Purchaser or another holder of a Note with a minimum net worth of at least Cdn.$50,000,000 (or its equivalent in the relevant currency) or a Qualified Institutional Buyer, such Person’s own unsecured agreement of indemnity shall be deemed to be satisfactory), or

(b) in the case of mutilation, upon surrender and cancellation thereof,

within ten Business Days thereafter the Company at its own expense shall execute and deliver, in lieu thereof, a new Note of the same series, dated and bearing interest from the date to which interest shall have been paid on such lost, stolen, destroyed or mutilated Note or dated the date of such lost, stolen, destroyed or mutilated Note if no interest shall have been paid thereon.

57

15. PAYMENTS ON NOTES.

15.1. Place of Payment.

Subject to Section 15.2, payments of principal, Make-Whole Amount, if any, Protective Claim Amount and interest becoming due and payable on the Notes shall be made in Calgary, Alberta at the principal office of the Company. The Company may at any time, by notice to each holder of a Note, change the place of payment of the Notes so long as such place of payment shall be either (i) the principal office of the Company in the United States of America or (ii) the principal office of a bank or trust company in the United States of America.

15.2. Home Office Payment.

So long as any Purchaser or its nominee shall be the holder of any Note, and notwithstanding anything contained in Section 15.1 or in such Note to the contrary, the Company will pay all sums becoming due on such Note for principal, Make-Whole Amount, if any, Protective Claim Amount and interest by the method and at the address specified for such purpose below such Purchaser’s name in Schedule A, or by such other method or at such other address as such Purchaser shall have from time to time specified to the Company in writing for such purpose, plus any wiring fees applicable to wire transfers of funds, without the presentation or surrender of such Note or the making of any notation thereon, except that upon written request of the Company made concurrently with or reasonably promptly after payment or prepayment in full of any Note, such Purchaser shall surrender such Note for cancellation, reasonably promptly after any such request, to the Company at its principal executive office or at the place of payment most recently designated by the Company pursuant to Section 15.1. Prior to any sale or other disposition of any Note held by a Purchaser or its nominee, such Purchaser will, at its election, either endorse thereon the amount of principal paid thereon and the last date to which interest has been paid thereon or surrender such Note to the Company in exchange for a new Note or Notes pursuant to Section 14.2. The Company will afford the benefits of this Section 15.2 to any Institutional Investor that is the direct or indirect transferee of any Note purchased by a Purchaser under this Agreement and that has made the same agreement relating to such Note as the Purchasers have made in this Section 15.2.

16. EXPENSES, ETC.

16.1. Transaction Expenses.

Whether or not the transactions contemplated hereby are consummated, the Company will pay all costs and expenses (including reasonable attorneys’ fees of a special counsel and, if reasonably required by the Required Holders, local or other counsel) incurred by the Purchasers and each other holder of a Note in connection with such transactions and in connection with any amendments, waivers or consents under or in respect of the Financing Agreements (whether or not such amendment, waiver or consent becomes effective), including, without limitation: (a) review of any events or transactions contemplated by Sections 7.1(l), 7.1(m), 7.1(n), 7.1(p), 9.9, 9.10, 9.11, 9.12, 9.13, 10.2, 10.11 and 23, (b) the costs and expenses incurred in enforcing or defending (or determining whether or how to enforce or defend) any rights under the Financing Agreements or in responding to any subpoena or other legal process or informal

The Company will pay, and will save each Purchaser and each other holder of a Note harmless from, all claims in respect of any fees, costs or expenses, if any, of brokers and finders (other than those, if any, retained by a Purchaser or other holder in connection with its purchase of the Notes).

16.2. Certain Taxes.

The Company agrees to pay all stamp, documentary or similar taxes or fees which may be payable in respect of the execution and delivery or the enforcement of the Financing Agreements or the execution and delivery (but not the transfer) or the enforcement of any of the Notes in the United States of America or Canada or of any amendment of, or waiver or consent under or with respect to, the Financing Agreements, and to pay any value added tax due and payable in respect of reimbursement of costs and expenses by the Company pursuant to this Section 16, and will save each holder of a Note to the extent permitted by applicable Laws harmless against any loss or liability resulting from nonpayment or delay in payment of any such tax or fee required to be paid by the Company hereunder.

16.3. Survival.

The obligations of the Company under this Section 16 will survive the payment or transfer of any Note, the enforcement, amendment or waiver of any provision of the Financing Agreements, and the termination of this Agreement.

17. SURVIVAL OF REPRESENTATIONS AND WARRANTIES; ENTIRE AGREEMENT.

All representations and warranties contained herein shall survive the execution and delivery of the Financing Agreements, the purchase or transfer by any Purchaser of any Note or portion thereof or interest therein and the payment of any Note, and may be relied upon by any subsequent holder of a Note, regardless of any investigation made at any time by or on behalf of such Purchaser or any other holder of a Note. All statements contained in any certificate or other instrument delivered by or on behalf of the Company or any Subsidiary pursuant to the Financing Agreements shall be deemed representations and warranties of the Company under this Agreement. Subject to the preceding sentence, the Financing Agreements embody the entire agreement and understanding between each Purchaser and the Company and supersede all prior agreements and understandings relating to the subject matter hereof.

59

18. AMENDMENT AND WAIVER.

18.1. Requirements.

This Agreement, the Notes and the other Financing Agreements may be amended, and the observance of any term hereof or of the Notes may be waived (either retroactively or prospectively), with (and only with) the written consent of the Company and the Required Holders, except that (a) no amendment or waiver of any of the provisions of Section 1, 2, 3, 4, 5, 6 or 22, or any defined term (as it is used therein), will be effective as to any Purchaser unless consented to by such Purchaser in writing, and (b) no such amendment or waiver may, without the written consent of the holder of each Note at the time outstanding affected thereby, (i) subject to the provisions of Section 12 relating to acceleration or rescission, change the amount or time of any prepayment or payment of principal of, or reduce the rate or change the time of payment or method of computation of interest or of the applicable Make-Whole Amount or Protective Claim Amount on, the Notes, (ii) change the percentage of the principal amount of the Notes the holders of which are required to consent to any such amendment or waiver, (iii) amend Section 8, 11(a), 11(b), 12, 13, 18, 21 or 23.10, or (iv) amend any provision of the Subordination Agreement, the Trust Guarantee, a Subsidiary Guarantee or any Lien granted to the holders of Notes pursuant to Section 9.13 or otherwise.

18.2. Solicitation of Holders of Notes.

(a) Solicitation. The Company will provide each holder of the Notes (irrespective of the amount of Notes then owned by it) with sufficient information, sufficiently far in advance of the date a decision is required, to enable such holder to make an informed and considered decision with respect to any proposed amendment, waiver or consent in respect of any of the provisions hereof or of the Notes. The Company will deliver executed or true and correct copies of each amendment, waiver or consent effected pursuant to the provisions of this Section 18 to each holder of outstanding Notes promptly following the date on which it is executed and delivered by, or receives the consent or approval of, the requisite holders of Notes.

(b) Payment. The Company will not directly or indirectly pay or cause to be paid any remuneration, whether by way of supplemental or additional interest, fee or otherwise, or grant any security or provide other credit support, to any holder of Notes as consideration for or as an inducement to the entering into by any holder of Notes of any waiver or amendment of any of the terms and provisions hereof unless such remuneration is concurrently paid, or security is concurrently granted or other credit support concurrently provided, on the same terms, ratably to each holder of Notes then outstanding even if such holder did not consent to such waiver or amendment.

18.3. Binding Effect, Etc.

Any amendment or waiver consented to as provided in this Section 18 applies equally to all holders of Notes and is binding upon them and upon each future holder of any Note and upon the Company without regard to whether such Note has been marked to indicate such amendment or waiver. No such amendment or waiver will extend to or affect any obligation, covenant, agreement, Default or Event of Default not expressly amended or waived or impair any right consequent thereon. No course of dealing between the Company and the holder of any Note nor any delay in exercising any rights hereunder or under any Note shall operate as a waiver of any rights of any holder of such Note. As used herein, the term “this Agreement” and references thereto shall mean this Agreement as it may from time to time be amended or supplemented.

60

18.4. Notes Held by Company, Etc.

Solely for the purpose of determining whether the holders of the requisite percentage of the aggregate principal amount of Notes then outstanding approved or consented to any amendment, waiver or consent to be given under this Agreement, the Notes or any other Financing Agreements, or have directed the taking of any action provided herein or therein to be taken upon the direction of the holders of a specified percentage of the aggregate principal amount of Notes then outstanding, Notes directly or indirectly owned by the Company or any of its Affiliates shall be deemed not to be outstanding.

19. NOTICES; ENGLISH LANGUAGE.

Except to the extent expressly provided otherwise in Sections 7.1(a) and 7.1(c), all notices and communications provided for hereunder shall be in writing and sent (a) by telecopy if the sender on the same day sends a confirming copy of such notice by a recognized international commercial delivery service (charges prepaid), (b) by a recognized international commercial delivery service (with charges prepaid), or (c) with respect to notices to a Purchaser or holder, unless such Purchaser or holders otherwise notifies the Company, by e-mail to an e-mail address provided by such Purchaser or holder to the Company from time to time. Any such notice must be sent:

(a) if to a Purchaser or its nominee, to such Purchaser or nominee at the address specified for such communications in Schedule A, or at such other address as such Purchaser or nominee shall have specified to the Company in writing,

(b) if to any other holder of any Note, to such holder at such address as such other holder shall have specified to the Company in writing, or

(c) if to the Company, to the Company at its address set forth at the beginning hereof to the attention of the Chief Financial Officer, or at such other address as the Company shall have specified to the holder of each Note in writing.

Each document, instrument, financial statement, report, notice or other communication delivered in connection with this Agreement shall be in English.

The Purchaser acknowledges and confirms that it has requested that all documents evidencing or relating in any way to the sale of the Notes be drawn up in the English language only.

20. REPRODUCTION OF DOCUMENTS.

This Agreement and all documents relating thereto, including, without limitation, (a) consents, waivers and modifications that may hereafter be executed, (b) documents received by any Purchaser at the Closing (except the Notes themselves), and (c) financial statements, certificates and other information previously or hereafter furnished to any Purchaser, may be reproduced by such Purchaser by any photographic, photostatic, electronic, digital or other similar

61

process and such Purchaser may destroy any original document so reproduced. The Company agrees and stipulates that, to the extent permitted by applicable Laws, any such reproduction shall be admissible in evidence as the original itself in any judicial or administrative proceeding (whether or not the original is in existence and whether or not such reproduction was made by such Purchaser in the regular course of business) and any enlargement, facsimile or further reproduction of such reproduction shall likewise be admissible in evidence. This Section 20 shall not prohibit the Company or any other holder of Notes from contesting any such reproduction to the same extent that it could contest the original, or from introducing evidence to demonstrate the inaccuracy of any such reproduction.

21. CONFIDENTIAL INFORMATION.

For the purposes of this Section 21, “Confidential Information” means all information delivered to any Purchaser by or on behalf of the Company or any Subsidiary in connection with the transactions contemplated by or otherwise pursuant to this Agreement that is proprietary in nature and that was clearly marked or labeled or otherwise adequately identified when received by such Purchaser as being confidential information of the Company or such Subsidiary, provided that such term does not include information that (a) was publicly known or otherwise known to such Purchaser prior to the time of such disclosure, (b) subsequently becomes publicly known through no act or omission by such Purchaser or any person acting on such Purchaser’s behalf, (c) otherwise becomes known to such Purchaser other than through disclosure by the Company or any Subsidiary or (d) constitutes financial statements delivered to such Purchaser under Section 7.1 that are otherwise publicly available. Each Purchaser will maintain the confidentiality of such Confidential Information in accordance with procedures adopted by such Purchaser in good faith to protect confidential information of third parties delivered to such Purchaser, provided that such Purchaser may deliver or disclose Confidential Information to (i) its directors, trustees, officers, employees, agents, attorneys, auditors and affiliates (to the extent such disclosure reasonably relates to the administration of the investment represented by its Notes), (ii) its financial advisors and other professional advisors who agree to hold confidential the Confidential Information substantially in accordance with the terms of this Section 21, (iii) any other holder of any Note, (iv) any Institutional Investor to which it sells or offers to sell such Note or any part thereof or any participation therein (if such Person has agreed in writing prior to its receipt of such Confidential Information to be bound by the provisions of this Section 21), (v) any Person from which it offers to purchase any security of the Company (if such Person has agreed in writing prior to its receipt of such Confidential Information to be bound by the provisions of this Section 21), (vi) any federal or state regulatory authority having jurisdiction over such Purchaser, (vii) any organization or any nationally recognized rating agency that requires access to information about such Purchaser’s investment portfolio (including the NAIC or the SVO or, in each case, any similar organization), or (viii) any other Person to which such delivery or disclosure may be necessary or appropriate (w) to effect compliance with any law, rule, regulation or order applicable to such Purchaser, (x) in response to any subpoena or other legal process, (y) in connection with any litigation to which such Purchaser is a party or (z) if an Event of Default has occurred and is continuing, to the extent such Purchaser may reasonably determine such delivery and disclosure to be necessary or appropriate in the enforcement or for the protection of the rights and remedies under such Purchaser’s Notes and this Agreement. Each holder of a Note, by its acceptance of a Note, will be deemed to have agreed to be bound by and to be entitled to the benefits of this Section 21 as though it were a party to this Agreement. On reasonable request by the Company in connection with the

62

delivery to any holder of a Note of information required to be delivered to such holder under this Agreement or requested by such holder (other than a holder that is a party to this Agreement or its nominee), such holder will enter into an agreement with the Company embodying the provisions of this Section 21.

In the event that as a condition to receiving access to information relating to the Company or its Subsidiaries in connection with the transactions contemplated by or otherwise pursuant to this Agreement, any holder of a Note is required to agree to a confidentiality undertaking (whether through IntraLinks, another secure website, a secure virtual workspace or otherwise) which is different from this Section 21, this Section 21 shall not be amended thereby and, as between such holder and the Company, this Section 21 shall supersede any such other confidentiality undertaking.

22. SUBSTITUTION OF PURCHASER.

Each Purchaser shall have the right to substitute any one of its Affiliates as the purchaser of the Notes that it has agreed to purchase hereunder, by written notice to the Company, which notice shall be signed by both such Purchaser and such Affiliate, shall contain such Affiliate’s agreement to be bound by this Agreement and shall contain a confirmation by such Affiliate of the accuracy with respect to it of the representations set forth in Section 6. Upon receipt of such notice, any reference to such Purchaser in this Agreement (other than in this Section 22), shall be deemed to refer to such Affiliate in lieu of such original Purchaser. In the event that such Affiliate is so substituted as a Purchaser hereunder and such Affiliate thereafter transfers to such original Purchaser all of the Notes then held by such Affiliate, upon receipt by the Company of notice of such transfer, any reference to such Affiliate as a “Purchaser” in this Agreement (other than in this Section 22), shall no longer be deemed to refer to such Affiliate, but shall refer to such original Purchaser, and such original Purchaser shall again have all the rights of an original holder of the Notes under this Agreement.

23. MISCELLANEOUS.

23.1. Successors and Assigns.

All covenants and other agreements contained in this Agreement by or on behalf of any of the parties hereto bind and inure to the benefit of their respective successors and assigns (including, without limitation, any subsequent holder of a Note) whether so expressed or not, except that, subject to Section 10.2, the Company may not assign or otherwise transfer any of its rights or obligations hereunder or under the Notes without the prior written consent of each holder. Nothing in this Agreement, expressed or implied, shall be construed to confer upon any Person (other than the parties hereto and their respective successors and assigns permitted hereby) any legal or equitable right, remedy or claim under or by reason of this Agreement.

23.2. Payments Due on Non-Business Days.

Anything in this Agreement or the Notes to the contrary notwithstanding (but without limiting the requirement in Section 8.5 that notice of any optional prepayment specify a Business Day as the date fixed for such prepayment), any payment of principal of or Make-Whole Amount, or interest on any Note that is due on a date other than a Business Day shall be made on

63

the next succeeding Business Day without including the additional days elapsed in the computation of the interest payable on such next succeeding Business Day; provided that if the maturity date of any Note is a date other than a Business Day, the payment otherwise due on such maturity date shall be made on the next succeeding Business Day and shall include the additional days elapsed in the computation of interest payable on such next succeeding Business Day.

23.3. Accounting Terms.

All accounting terms used herein which are not expressly defined in this Agreement have the meanings respectively given to them in accordance with GAAP. Except as otherwise specifically provided herein, all computations made pursuant to this Agreement shall be made in accordance with GAAP, and all financial statements shall be prepared in accordance with GAAP. If GAAP is changed such that shareholders’ equity of the Company as shown on the consolidated balance sheet of the Company as at the date hereof is recharacterized as a non-equity item, then Consolidated Shareholders’ Equity will be determined on the basis of GAAP as in effect immediately prior to such recharacterization and, for certainty, such shareholders’ equity as so recharacterized shall not be included as part of Consolidated Total Debt. In addition, if GAAP is changed to reclassify operating leases to capital leases subsequent to the date of the Original Note Agreement, then the accounting treatment of all such leases will be determined based on GAAP in effect immediately prior to such reclassification.

For purposes of determining compliance with the financial covenants contained in this Agreement, any election by the Company to measure an item of Debt using fair value (as permitted by Accounting Standard Codification Topic No. ▇▇▇-▇▇-▇▇ – Fair Value Option, International Accounting Standard 39 or any similar accounting standard) shall be disregarded and such determination shall be made as if such election had not been made.

23.4. Changes in GAAP; IFRS.

(a) If the Company or the Required Holders determine at any time that any amount required to be determined hereunder would be materially different if such amount were determined in accordance with:

(i) GAAP applied by the Company in respect of its financial statements on the date hereof (“Old GAAP”), rather than

(ii) GAAP subsequently in effect in Canada and applied by the Company in respect of its financial statements (including the adoption of IFRS) and utilized for purposes of determining such amount,

then written notice of such determination shall be delivered by the Company to the holders, in the case of a determination by the Company, or by the Required Holders to the Company and the other holders, in the case of a determination by the Required Holders.

(b) If the Company adopts a change in an accounting policy in the preparation of its financial statements in order to conform to accounting recommendations, guidelines, or similar pronouncements, or legislative requirements, and such change could reasonably be expected to adversely affect (i) the rights of, or the protections afforded to, the holders hereunder

64

or (ii) the position of either the Company or of the holders hereunder, the Company shall so notify the holders, describing the nature of the change and its effect on the current and immediately prior year’s financial statements in accordance with Old GAAP and in detail sufficient for the holders to make the determination required of them in the following sentence. If either the Company or the Required Holders determine at any time that such change in accounting policy results in an adverse change either (A) in the rights of, or protections afforded to, the holders intended to be derived, or provided for, hereunder or (B) in the position of either the Company or of the holders hereunder, written notice of such determination shall be delivered by the Company to the holders, in the case of a determination by the Company, or by the Required Holders to the Company and the other holders, in the case of a determination by the Required Holders.

(c) The written notice to be provided pursuant to Section 23.4(a) or Section 23.4(b) by the Company or the holders (as the case may be) shall include a proposal with respect to the change in Old GAAP or such change in accounting policy, as the case may be, on how to preserve and protect the intended rights of, or protections afforded to, the holders on the date hereof or the position of the Company or the holders (as the case may be) and thereafter the Company and the holders shall in good faith negotiate to execute and deliver an amendment or amendments to this Agreement in order to preserve and protect the intended rights of, or protections afforded to, the holders on the date hereof or the position of the Company or the holders (as the case may be); provided that, until this Agreement has been amended in accordance with the foregoing, then for all purposes hereof, the applicable changes from Old GAAP or in accounting (as the case may be) shall be disregarded hereunder and any amount required to be determined hereunder shall, nevertheless, continue to be determined under Old GAAP and the Company’s prior accounting policy. For the purposes of this Section 23.4(c), the Company and the holders acknowledge that the amendment or amendments to this Agreement are to provide substantially the same rights and protections to the holders as is intended by this Agreement on the date hereof. Until the Company and the Required Holders mutually agree (in their respective sole discretions, without any obligation to so agree) on such amendment or amendments to the Agreement, the Company shall continue to determine amounts required under this Agreement in accordance with Old GAAP and, for all purposes hereof, the applicable changes from Old GAAP or in accounting (as the case may be) shall be disregarded hereunder and any amount required to be determined hereunder shall, nevertheless, continue to be determined under Old GAAP and the Company’s prior accounting policy.

23.5. Severability.

Any provision of this Agreement that is prohibited or unenforceable in any jurisdiction shall, as to such jurisdiction, be ineffective to the extent of such prohibition or unenforceability without invalidating the remaining provisions hereof, and any such prohibition or unenforceability in any jurisdiction shall (to the full extent permitted by law) not invalidate or render unenforceable such provision in any other jurisdiction.

23.6. Construction, Etc.

Each covenant contained herein shall be construed (absent any express provision to the contrary) as being independent of each other covenant contained herein, so that compliance with any one covenant shall not (absent such an express contrary provision) be deemed to excuse compliance with any other covenant. Where any provision herein refers to action to be taken by any Person, or which such Person is prohibited from taking, such provision shall be applicable whether such action is taken directly or indirectly by such Person.

65

Defined terms herein shall apply equally to the singular and plural forms of the terms defined. Whenever the context may require, any pronoun shall include the corresponding masculine, feminine and neuter forms. The words “include,” “includes” and “including” shall be deemed to be followed by the phrase “without limitation.” The word “will” shall be construed to have the same meaning and effect as the word “shall.” Unless the context requires otherwise (a) any definition of or reference to any agreement, instrument or other document herein shall be construed as referring to such agreement, instrument or other document as from time to time amended, supplemented or otherwise modified (subject to any restrictions on such amendments, supplements or modifications set forth herein) and, for purposes of the Notes, shall also include any such notes issued in substitution therefor pursuant to Section 14, (b) subject to Section 23.1, any reference herein to any Person shall be construed to include such Person’s successors and assigns, (c) the words “herein,” “hereof” and “hereunder,” and words of similar import, shall be construed to refer to this Agreement in its entirety and not to any particular provision hereof, (d) all references herein to Sections and Schedules shall be construed to refer to Sections of, and Schedules to, this Agreement, and (e) any reference to any law or regulation herein shall, unless otherwise specified, refer to such law or regulation as amended, modified or supplemented from time to time.

23.7. Counterparts.

This Agreement may be executed in any number of counterparts, each of which shall be an original but all of which together shall constitute one instrument. Each counterpart may consist of a number of copies hereof, each signed by less than all, but together signed by all, of the parties hereto.

23.8. Governing Law.

This Agreement shall be construed and enforced in accordance with, and the rights of the parties shall be governed by, the law of the Province of Alberta excluding choice-of-law principles of the law of such Province that would permit the application of the laws of a jurisdiction other than such Province.

23.9. Jurisdiction and Process; Waiver of Jury Trial.

(a) The Company irrevocably submits to the non-exclusive jurisdiction of the courts of the Province of Alberta over any suit, action or proceeding arising out of or relating to the Financing Agreements. To the fullest extent permitted by applicable Laws, the Company irrevocably waives and agrees not to assert, by way of motion, as a defense or otherwise, any claim that it is not subject to the jurisdiction of any such court, any objection that it may now or hereafter have to the laying of the venue of any such suit, action or proceeding brought in any such court and any claim that any such suit, action or proceeding brought in any such court has been brought in an inconvenient forum.

66

(b) The Company agrees, to the fullest extent permitted by applicable Laws, that a final judgment in any suit, action or proceeding of the nature referred to in Section 23.9(a) brought in any such court shall be conclusive and binding upon it subject to rights of appeal, as the case may be, and may be enforced in the courts of the Province of Alberta (or any other courts to the jurisdiction of which it or any of its assets is or may be subject) by a suit upon such judgment.

(c) Nothing in this Section 23.9 shall affect the right of any holder of a Note to serve process in any manner permitted by law, or limit any right that the holders of any of the Notes may have to bring proceedings against the Company in the courts of any appropriate jurisdiction or to enforce in any lawful manner a judgment obtained in one jurisdiction in any other jurisdiction.

(d) THE PARTIES HERETO HEREBY WAIVE TRIAL BY JURY IN ANY ACTION BROUGHT ON OR WITH RESPECT TO THIS AGREEMENT, THE NOTES OR ANY OTHER DOCUMENT EXECUTED IN CONNECTION HEREWITH OR THEREWITH.

23.10. Obligation to Make Payment in Applicable Currency.

(a) Payment Currency. Principal, interest, Make-Whole Amount and Protective Claim Amount on the Series S Notes shall be payable in U.S. dollars. Unless otherwise specified herein, all other amounts payable under this Agreement shall be payable in U.S. dollars.

(b) U.S. Dollars. Any payment on account of an amount that is payable under the Financing Agreements in U.S. dollars which is made to or for the account of any holder of Notes in any other currency, whether as a result of any judgment or order or the enforcement thereof or the realization of any security or the liquidation of the Company, shall constitute a discharge of the obligation of the Company under the Financing Agreements only to the extent of the amount of U.S. dollars which such holder purchases or could purchase in the foreign exchange markets in New York, New York, with the amount of such other currency in accordance with normal banking procedures at the rate of exchange prevailing on the Business Day following receipt of the payment first referred to above. If the amount of U.S. dollars so purchased or that could be purchased is less than the amount of U.S. dollars originally due to such holder, the Company agrees to the fullest extent permitted by law, to indemnify and save harmless such holder from and against all loss or damage arising out of or as a result of such deficiency. This indemnity shall, to the fullest extent permitted by law, constitute an obligation separate and independent from the other obligations contained in the Financing Agreements, shall give rise to a separate and independent cause of action, shall apply irrespective of any indulgence granted by such holder from time to time and shall continue in full force and effect notwithstanding any judgment or order for a liquidated sum in respect of an amount due under the Financing Agreements or under any judgment or order.

23.11. Interest.

(a) In respect of any overdue amounts hereunder or under the Notes where no provision is made herein or therein for payment of interest thereon, the Company shall pay interest on such overdue amounts on demand, calculated from the date such unpaid amount is due until such unpaid amount is paid in full, at the Default Rate.

67

(b) In no event shall any interest or fee to be paid hereunder or under a Note exceed the maximum rate permitted by applicable Laws. In the event any such interest rate or fee exceeds such maximum rate, such rate shall be adjusted downward to the highest rate (expressed as a percentage per annum) or fee that the parties could validly have agreed to by contract on the date hereof under applicable Laws. It is further agreed that any excess actually received by a holder of a Note shall be credited against the principal of the Notes (or, if the principal shall have been or would thereby be paid in full, the remaining amount shall be credited or paid to the Company).

(c) All interest (including interest on overdue interest) payable by the Company hereunder and under the Notes shall accrue from day to day, computed as provided herein, and shall be payable after as well as before maturity, demand, default and judgment.

(d) Interest on the Notes shall be computed on the basis of a 360-day year of 12 30-day months. Solely for purposes of the Interest Act (Canada), the yearly rate of interest to which interest calculated for a period of less than one year on the basis of a year of 360 days consisting of 12 30-day periods is equivalent is such rate of interest multiplied by a fraction of which (i) the numerator is the product of (A) the actual number of days in the year commencing on the first day of such period, multiplied by (B) the sum of (y) the product of 30 multiplied by the number of complete months elapsed in such period and (z) the actual number of days elapsed in any incomplete month in such period; and (ii) the denominator is the product of (a) 360 multiplied by (b) the actual number of days in such period.

(e) The theory of “deemed reinvestment” shall not apply to the computation of interest and no allowance, reduction or deduction shall be made for the deemed reinvestment of interest in respect of any payments. Calculation of interest shall be made using the nominal rate method, and not the effective rate method, of calculation.

(f) To the extent permitted by law, Section 6 of the Judgment Interest Act (Alberta) is hereby waived and shall not apply to this Agreement or the Notes.

(g) The interest payment due on the day prior to the maturity date of each Note shall include one additional days’ interest, calculated as if such interest due date was such final maturity date.

23.12. Changes to LMR.

If (a) as a result of any change in any applicable Laws, rule, policy, regulation, order or directive, any applicable Energy Regulator ceases to use a liability management (or equivalent) rating as a means of determining whether a corporation is in compliance with such regulator’s abandonment and reclamation policies, regulations and directives in any one or more Material Jurisdiction, (b) the method of calculation of any LMR changes in any material manner in any Material Jurisdiction, or (c) if the threshold for which (i) license transfers of regulated properties shall be permitted under an Energy Regulator’s licensee liability regime in any Material Jurisdiction changes in any material respect or (ii) any security deposits will be required to be provided to the applicable Energy Regulator changes in any material respect, then, in any such case, the Company and the Required Holders shall enter into good faith discussions with a view to

68

determining a comparable rating system or threshold, as applicable, to replace the concept of LMR as set forth herein that is, at such time, broadly accepted as the prevailing market practice for such regulation in the applicable Material Jurisdiction, with the intent of having the respective positions of the holders of Notes and the Company after such change conform as nearly as possible to their respective positions immediately prior to such change; provided that, until any such agreement is reached, the LMR shall continue to be calculated as if no such change had occurred. Upon the Company and the Required Holders agreeing on such methodology for determining LMR and the thresholds set forth herein, the Company and the holders of Notes shall enter into documentation to amend the provisions hereof to refer to such rate and make all other adjustments incidental thereto. The Company and the holders of Notes agree that such amendment shall require the consent of each of the holders of Notes notwithstanding anything to the contrary set out herein.
