“9.16

Security Prior to Security Release Date

(a)

From and after the Effective Date 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 favour 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

- 7 -

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.

(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 (i) 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 or (ii) the Liens in respect of the Security except in accordance with Section 9.16(g) and the Intercreditor Agreement.

(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

- 8 -

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 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; and

(ii)

the later of (A) such time when both (1) the Consolidated Senior Leverage Ratio has been less than 3:1 at the end of each of the then most recent four consecutive fiscal quarters of the Company and (2) an Investment Grade Rating for the Company’s senior unsecured Indebtedness is in effect, and (B) the end of the Covenant Relief Period.

(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.

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

Land Schedule.

The Company will, not later than 60 days following the date of the Second Amending Agreement, provide to the Collateral Agent a land schedule in form satisfactory to the Required Holders, acting reasonably, detailing all of the oil and gas properties held by the Company and the Subsidiary Guarantors (which shall include legal

- 9 -

descriptions, crown lease numbers and issue dates, reserve numbers, zone restrictions, names of freehold lessors, before and after payout working interests and all royalties and burdens).

9.20

Hedging Plan.

At all times during the Covenant Relief Period, the Company will comply with the Hedging Plan as in effect on the Effective Date. Following the Covenant Relief Period, the Company will comply with the Hedging Plan, as such plan may be amended from time to time after the end of the Covenant Relief Period 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.”

- 16 -

pro rata share (or such lesser amount as such holder shall have specified in its Response Notice) of the Aggregate Excess Amount (if any) if such holder has exercised the Excess Amount Election (such pro rata share for such holder to be equal to the percentage that the outstanding principal amount of such holder’s Notes as to which such holder has exercised the Excess Amount Election is of the aggregate outstanding principal amount of all Outstanding Notes in respect of which the prepayment offer has been made and as to which the holders thereof have exercised the Excess Amount Election). The amount paid to a holder of Notes in respect of the Excess Amount Election shall be allocated to the Notes held by such holder of such series and in such manner as such holder shall elect (and such holder shall give the Company written notice describing such election promptly after it has been made). The Company shall prepay on the Disposition Prepayment Date the amount set forth in such notice plus interest accrued thereon to the Disposition Prepayment Date, but without any Make-Whole Amount or other premium, with respect to each Note held by the holders that have accepted such offer in accordance with this Section 10.10.

(g) To the extent that any portion of the Excess Amount is not applied to prepay the Outstanding Notes to which the applicable prepayment offer was made, such portion may be used by the Company to repay advances under the Bank Facility (without any corresponding reduction in the lending commitments thereunder with respect to any such repayment made during the Covenant Relief Period) or for general corporate purposes.

(h) For the avoidance of doubt, a “Disposition” shall include any sale of farmout interests, net profit interests, reversionary interests, overriding royalty interests, carried interests or other similar interests by the Company or any of its Restricted Subsidiaries.

(i) In determining the outstanding principal amount of any Senior Indebtedness for purposes of this Section 10.10, including without limitation in respect of any of the Outstanding Notes, any such Senior Indebtedness denominated in a currency other than Canadian dollars shall be converted to Canadian dollars at the applicable daily noon rate quoted by the Bank of Canada on the date of determination to purchase in Toronto, Ontario such other currency with Canadian dollars.”

Consolidated Senior Leverage Ratio				Basis Points Per Annum
less than or equal to 3:1				[Redacted]
greater than 3:1 and less than or equal to 4:1				[Redacted]
greater than 4:1 and less than or equal to 4.5:1				[Redacted]
greater than 4.5:1				[Redacted]

- 27 -

If, on the date an interest payment is due hereunder, the Company has not yet delivered its compliance certificate for the then most recently ended fiscal quarter in accordance with Section 7.2 of the Note Purchase Agreement setting forth its Consolidated Senior Leverage Ratio as of the last day of such fiscal quarter, the interest payment due on such date shall be calculated without giving effect to this paragraph but any additional amount payable as the result of this paragraph shall be paid on the date of delivery of the compliance certificate in respect of such fiscal quarter (or the last date for delivery of such certificate if it shall not be delivered on or prior to such last date), as provided in Section 7.2(a) of the Note Purchase Agreement. If such compliance certificate is not delivered on the last date for delivery thereof, it shall be assumed that the Consolidated Senior Leverage Ratio as of the end of such fiscal quarter was greater than 4.5 to 1. If the interest rate hereunder for all or any portion of the period preceding an interest payment date shall be calculated by reference to this paragraph (as well as the preceding paragraph), the Company shall give written notice to the holder hereof on, or within 10 Business Days prior to, such interest payment date specifying in reasonable detail the calculation of the amount of interest payable on such interest payment date.”

(b) Upon the request of any holder and upon surrender to the Company of any Note held by it, the Company shall execute and deliver a new Note or Notes (as specified by such holder) reflecting the changes set forth in Section 2.14(a) of this Agreement, registered in the name of such holder, in an aggregate principal amount equal to the then unpaid principal amount of such surrendered Note and dated the date of the last interest payment made to such holder in respect of such surrendered Note.

ARTICLE 3

ADDITIONAL TERMS AND COVENANTS

3.1

Most Favored Lender

(a) If the Bank Facility, or any guarantee by a Subsidiary of the Company’s obligations thereunder, or any Other Note Agreement or any guarantee by a Subsidiary of the Company’s obligations thereunder (the Bank Facility, each Other Note Agreement and any of such guarantees being referred to, collectively, as an “MFL Document”), shall be amended, modified or supplemented after the date hereof and during the Covenant Relief Period, whether directly or indirectly, and the effect of such amendment, modification or supplement shall be to impose on the Company or any Subsidiary Guarantor any one or more conditions, covenants, events of default or other terms (other than those referred to in Section 3.2 of this Agreement) that are not contained herein, in the Note Agreement or in the Subsidiary Guarantee (the “Relevant Documents”), or that would, if incorporated into the Relevant Documents, be more favorable to the holders of the Notes than the conditions, covenants, events of default or other terms contained in the Relevant Documents (any such condition, covenant, event of default or other term being referred to herein as a “More Favorable Provision”), then, subject to Section 3.1(b), such More Favorable Provision shall be automatically incorporated in the Relevant Document as if set forth fully therein, mutatis mutandis, and shall be effective as of the date such More Favorable Provision becomes effective in the relevant MFL Document. Thereafter, such More Favorable Provision may only be amended in accordance with the provisions of the Note Agreement.

- 28 -

(b) The Company shall give written notice to each holder of Notes of the effectiveness of any More Favorable Provision within 10 days after execution of the document containing such More Favorable Provision, which notice shall include a copy of such document. If the Required Holders give written notice to the Company, within 20 days after receipt of the Company’s notice, objecting to the inclusion of such More Favorable Provision in the Relevant Document, such More Favorable Provision shall not be incorporated in the Relevant Document.

(c) Upon the written request of the Company or the Required Holders, the Company or the Subsidiary Guarantors, as applicable, and the Required Holders shall enter into an amendment of the Relevant Document to reflect the inclusion of the More Favorable Provision. All costs of the holders of the Notes incurred in connection with any such amendment (including, without limitation, the reasonable fees and expenses of counsel to the holders) shall be paid by the Company promptly after its receipt of a statement in respect thereof.

(d) For the avoidance of doubt, all of the provisions of any Relevant Document shall otherwise remain in effect notwithstanding the incorporation therein of one or more More Favorable Provisions.

3.2

Equivalent Consideration

(a) If the Bank Facility shall be amended, modified or supplemented after the date hereof and during the Covenant Relief Period, whether directly or indirectly, and the effect of such amendment, modification or supplement shall be to

(i) increase the margin used to determine the interest rate applicable to any loan under the Bank Facility during the Covenant Relief Period, or

(ii) change the reference rate used to determine such interest rate and the effect of such change shall be an increase in the interest rate applicable to any loan under the Bank Facility during the Covenant Relief Period compared to the rate that would be in force without giving effect to such amendment, modification or supplement,

then the interest rate applicable to any Note shall be the interest rate otherwise in effect therefor plus a number of Basis Points equal to the interest rate increase (expressed in Basis Points) applicable from time to time to any loan under the Bank Facility as a result of such amendment. The increased interest rate applicable to the Notes shall be effective as of the date of effectiveness of the increased interest rate applicable to such loan and shall remain in effect until the earlier of (A) the end of the Covenant Relief Period or (B) the date such increased interest rate shall no longer apply to such loan.

(b) If, during the Covenant Relief Period, any fee shall be paid to any Lender solely in its capacity as a Lender under the Bank Facility (and not, for greater certainty, as a “Fronting Lender” or “Agent”, as defined in the Bank Facility) in excess of, or in addition to, any fee payable to such Lender under the Bank Facility as in effect on the date hereof, then a fee shall be paid to the holder of each Note in an amount which bears the same relationship to the principal amount of such Note as the amount of such excess or such addition bears to the amount of the Bank Facility related obligation or commitment to which such excess or addition relates.

- 29 -

(c) If, during the Covenant Relief Period, any consideration shall be paid to each Lender solely in their capacity as such (and not, for greater certainty, in any of their capacities as a counterparty under any Hedging Agreement or Banking Services Agreement and not including (i) any withholding tax gross-up payment or other compensatory payment made to a Lender on account of any increased costs or reduced returns incurred or suffered by such Lender from a change in law, compliance by such Lender with regulatory requirements or otherwise; (ii) any extension fee payable to the Lenders solely in connection with extending the maturity date of the Bank Facility; or (iii) any other amounts payable to any Lender in connection with transactions, advisory services or other services of any kind entered into or provided by such Lender to the Company or any Affiliate of the Company where such transactions or services are not directly related to the Bank Facility), other than as specified in the foregoing paragraphs (a) and (b), then the equivalent of such consideration shall be paid to each holder of Notes.

3.3

Fees and Expenses of Petroleum Engineer and Financial Advisor

During the Covenant Relief Period, the Company shall pay the reasonable fees and expenses of (i) ▇▇▇▇▇▇▇▇ and ▇▇▇▇▇▇▇▇▇▇▇ Canada Limited or another petroleum engineer engaged by the Majority Noteholders (or legal counsel on their behalf) and (ii) FTI Consulting, Inc. or another financial advisor engaged by the Majority Noteholders (or legal counsel on their behalf), in each case as provided in the respective engagement letters to which the Company and such petroleum engineer or financial advisor are parties; provided, however, that at no time shall the Company be required to pay, pursuant to this Section 3.3, the fees and expenses of more than one petroleum engineer and one financial advisor engaged by, or on behalf of, any one or more holders of Notes.
