THOSE FINANCIAL INSTITUTIONS WHICH

UNDER THIS AGREEMENT

PREAMBLE

WHEREAS the Borrower, the Agent and certain of the Lenders are parties to an amended and restated credit agreement dated March 31, 2006 (the "Original Credit Agreement");

AND WHEREAS the Borrower has requested and the Lenders have agreed to amend and restate the Original Credit Agreement on the terms and conditions and for the purposes set out in this Agreement;

AND WHEREAS CIBC has agreed to act as Agent for the Lenders on the terms and conditions and for the purposes set out in this Agreement.

AGREEMENT

In consideration of the covenants and agreements between the Parties contained in this Agreement and other good and valuable consideration, the receipt and sufficiency of which are hereby acknowledged, the Parties agree as follows:

ARTICLE 1
INTERPRETATION

1.1               Definitions. Capitalized words and phrases used in the Documents, the Schedules hereto and in all notices and communications expressed to be made pursuant to this Agreement

-2-

will have the meanings set out in Schedule A, unless otherwise defined in any of the Documents.

1.2               Headings. Headings, subheadings and the table of contents contained in any of the Documents are inserted for convenience of reference only and will not affect the construction or interpretation of any of the Documents.

1.3              Subdivisions. Unless otherwise stated, reference herein to a Schedule or to an Article, Section, paragraph or other subdivision is a reference to such Schedule to this Agreement or such Article, Section, paragraph or other subdivision of this Agreement. Reference in Schedule A to a Schedule or to an Article, Section, paragraph or other subdivision of "this Agreement" is a reference to such Schedule or Article, Section, paragraph or other subdivision of this Agreement.

1.4               Number. Wherever the context in any of the Documents so requires, a term used herein importing the singular will also include the plural and vice versa.

1.5              Statutes, Regulations and Rules. Any reference in any of the Documents to all or any section or paragraph or any other subdivision of any Law will, unless otherwise expressly stated, be a reference to that Law or the relevant section or paragraph or other subdivision thereof, as amended, substituted, replaced or re-enacted from time to time.

1.6               Monetary References. Whenever an amount of money is referred to in any of the Documents, such amount will, unless otherwise expressly stated, be in Canadian Dollars.

1.7               Time. Time will be of the essence of the Documents.

1.8               Governing Law. The Documents will be governed by and construed in accordance with the Laws in force in the Province of Alberta from time to time.

1.9               Enurement. The Documents will be binding upon and will enure to the benefit of the Parties and their respective successors and permitted assigns.

1.10             Amendments. No Document may be amended orally and, subject to Sections 1.11(a), 21.16 and 22.1(1) any amendment may only be made by way of an instrument in writing signed by the Parties.

1.11             No Waiver.

(a)     Subject to Sections 1.11(c) and 21.16(a), no waiver by a Party of any provision or of the breach of any provision of any of the Documents will be effective unless it is contained in a written instrument duly executed by an authorized officer or representative of such Party. Such written waiver will affect only the matter specifically identified in the instrument granting the waiver and will not extend to any other matter, provision or breach.

(b)    The failure of a Party to take any steps in exercising any right in respect of the breach or non-fulfilment of any provision of any of the Documents will not

3

operate as a waiver of that right, breach or provision, nor will any single or partial exercise of any right preclude any other or future exercise of that right or the exercise of any other right, whether in Law or otherwise.

(c)     Acceptance of payment by a Party after a breach or non-fulfilment of any provision of any of the Documents requiring a payment to such Party will constitute a waiver of such provision if cured by such payment, but will not constitute a waiver or cure of any other provision of any of the Documents.

1.12           Severability. If the whole or any portion of the Documents or the application thereof to any circumstance will be held invalid or unenforceable to an extent that does not affect the operation of the Document in question in a fundamental way, the remainder of the provision in question, or its application to any circumstance other than that to which it has been held invalid or unenforceable, and the remainder of the Document in question, will not be affected thereby and will be valid and enforceable to the fullest extent permitted by Law.

1.13           Inconsistency. To the extent that there is any inconsistency or ambiguity between the provisions of this Agreement and any other Document, the provisions of this Agreement will govern to the extent necessary to eliminate such inconsistency or ambiguity.

1.14            Accounting Terms and Principles. Except as otherwise expressly provided, all accounting terms, principles and calculations applicable to the Credit Facilities will be interpreted, applied and calculated, as the case may be, in accordance with GAAP published from time to time in the Handbook. The basis of accounting and all calculations set out in this Agreement will be applied and made on a consistent basis and will not be changed for the purposes of this Agreement unless agreed to by the Agent in writing, such agreement not to be unreasonably withheld. It will be reasonable for the Agent to withhold its consent if a proposed change could adversely affect the obligations of the Borrower or the rights of the Agent and the Lenders hereunder.

ARTICLE 2
CREDIT FACILITIES

2.1              The Credit Facilities.

(a)     Revolving Facility. Subject to the terms and conditions hereof and effective as of the Effective Time, the Revolving Lenders hereby establish the Revolving Facility in favour of the Borrower in the Aggregate Commitment Amount set forth in Schedule B, which may be drawn by the Borrower in Canadian Dollars or the Canadian Dollar Exchange Equivalent thereof in U.S. Dollars, or any combination thereof. The Individual Commitment Amount of each Revolving Lender under the Revolving Facility is set out in Schedule B. The Borrower may borrow, repay and re-borrow any amount of the Individual Commitment Amount of each Revolving Lender under the Revolving Facility based on such Revolving Lender's Rateable Portion under the Revolving Facility.

(b)    Bridge Facility. Subject to the terms and conditions hereof and effective as of the Effective Time, the Bridge Lenders hereby establish the Bridge Facility in favour of the Borrower in the Aggregate Commitment Amount set forth in Schedule B, which may be drawn by the Borrower in Canadian Dollars or the Canadian Dollar Exchange Equivalent thereof in U.S. Dollars, or any combination thereof. The Individual Commitment Amount of each Bridge Lender under the Bridge Facility is set out in Schedule B. The Bridge Facility is non-revolving and may only be drawn by a single Drawdown within five Banking Days after the Closing Date. Accordingly, any undrawn portion of a Bridge Lender's Individual Commitment Amount under the Bridge Facility shall be immediately cancelled after the earlier of such single Drawdown and the close of business on the fifth Banking Day after the Closing Date and any amounts repaid to a Bridge Lender hereunder shall reduce such Bridge Lender's Individual Commitment Amount under the Bridge Facility and may not be reborrowed again.

2.2              Extension of Revolving Facility Termination Date.

(a)     Notice by Borrower. The Borrower may, at its option, request that the then existing Revolving Facility Termination Date of those Revolving Lenders which are not then Non-Extending Lenders be extended for extension periods of one, two or three years (an "Extension") by sending an extension request (an

5

"Extension Request") to the Agent not less than 60 days and not more than 90 days before any Anniversary Date (each a "Request Period"), provided that following the granting of such Extension, the Revolving Facility Termination Date shall not be extended beyond three years from such Anniversary Date. The Agent will promptly after receipt thereof provide a copy of the Extension Request to each of the Revolving Lenders which is not then a Non-Extending Lender. If the Borrower fails to make an Extension Request within the Request Period, the Revolving Facility will no longer be capable of being extended as herein provided until the Request Period applicable to the next Anniversary Date and, unless so extended, the Revolving Facility will continue until the then current Revolving Facility Termination Date with each Revolving Lender's Individual Commitment Amount under the Revolving Facility remaining available for Drawdown during such time. Notwithstanding the foregoing, the initial Extension Request cannot be sent until the Borrower delivers to the Lenders the December 31, 2006 annual audited consolidated financial statements of the Trust in accordance with Section 14.1 (a) and the December 31, 2006 Independent Reserve Report in accordance with Section 14.1(d).

(b)    Extending and Non-Extending Lenders. Each Revolving Lender which has not previously become a Non-Extending Lender, may in its sole discretion, pursuant to an Extension Request, elect to extend the current Revolving Facility Termination Date with respect to its Individual Commitment Amount under the Revolving Facility, subject however to such conditions and amendments respecting the Revolving Facility, if any, as the Extending Lenders unanimously agree upon and are acceptable to the Borrower. Each such Revolving Lender will make its election by notice to the Agent on or before the later of (i) 30 days from the date of the Extension Request, and (ii) 30 days after the Borrower delivers to the Lenders the most recent annual audited consolidated financial statements of the Trust in accordance with Section 14.1(a) and the most recent Independent Engineering Report in accordance with Section 14.1(d) (the "Election Period"). Each Revolving Lender which grants an Extension is referred to herein as an "Extending Lender", and each Revolving Lender which elects not to grant an Extension, or fails to make such election within the Election Period, is referred to herein as a "Non-Extending Lender".

(c)     No Extension. No Extension shall occur unless those Revolving Lenders who wish to grant an Extension pursuant to an Extension Request represent at least 662/3% of the aggregate Individual Commitment Amounts of all Revolving Lenders under the Revolving Facility who are not Non-Extending Lenders at the time of such Extension Request. If an Extension is not requested during a Request Period or a requested Extension is not granted by the requisite percentage of Revolving Lenders, the then current Revolving Facility Termination Date of a Revolving Lender will, subject to Section 2.2(e), continue for such Revolving Lender and such Revolving Lender's Individual Commitment Amount under the Revolving Facility will remain available for Drawdown in accordance with Section 2.1(a) until its Revolving Facility Termination Date; provided that, unless a Revolving Lender has previously become a Non-Extending Lender, the

6

Borrower may again make an Extension Request to such Revolving Lender during the Request Period applicable to the next Anniversary Date in accordance with Section 2.2(a).

(d)     Extension Notice. Promptly after the expiry of the Election Period, the Agent will notify the Borrower of the decision of the Revolving Lenders with respect to its Extension Request (the "Extension Notice"). The Extension Notice will identify the Extending Lenders and Non-Extending Lenders, the term of the Extension, if granted, and a list of the conditions or amendments, if any, respecting the Revolving Facility as the Extending Lenders have unanimously agreed upon as a condition to the granting of the Extension. The Borrower will, within 20 days of receipt of the Extension Notice from the Agent, notify the Agent as to its acceptance or rejection of the conditions or amendments, if any, stipulated by the Extending Lenders respecting the Revolving Facility. If the Borrower accepts all such conditions or amendments requested by the Extending Lenders, the Revolving Facility Termination Date with respect to the Extending Lenders will be deemed to have been extended for that period of time set out in the Extension Notice and subject to Section 2.2(e), the Revolving Facility Termination Date with respect to the Non-Extending Lenders shall not be extended. If the Borrower notifies the Agent that it does not accept such conditions or amendments or fails to notify the Agent within the time provided above for acceptance, the Revolving Facility Termination Date will not be extended as herein provided and will continue until the Revolving Facility Termination Date with each Lenders' Individual Commitment Amount under the Revolving Facility remaining available for Drawdown until the Revolving Facility Termination Date; provided that the Borrower may again make an Extension Request during the Request Period applicable to the next Anniversary Date in accordance with Section 2.2(a).

(e)     Replacement of Non-Extending Lender. Notwithstanding Section 2.5, and provided that Revolving Lenders representing more than 662/3% of the aggregate Individual Commitment Amounts of all Extending Lenders have elected to grant an Extension, the Borrower will be entitled to exercise one or more of the following options, with respect to any Revolving Lender who has become a Non- Extending Lender, prior to the Revolving Facility Termination Date applicable to such Non-Extending Lender:

(i)      provided that no Default or Event of Default has occurred and is continuing, the Borrower may repay all (or part if the entire remaining portion of the applicable Individual Commitment Amount under the Revolving Facility is placed in acceptance with (ii) below) of the Principal Amount owing to such Revolving Lender under the Revolving Facility, together with all accrued but unpaid interest and fees thereon and any breakage costs determined in accordance with Section 8.2, provided that a Bankers' Acceptance will not be prepaid prior to its Maturity Date (except the Borrower may provide Escrow Funds therefor in accordance with Section 18.4), and upon such payment such Revolving Lender's Individual

7

Commitment Amount under the Revolving Facility (or the applicable part thereof) will be permanently cancelled; or

(ii)     the Borrower may replace the Non-Extending Lender with another financial institution acceptable to the Agent, acting reasonably, who purchases such Revolving Lender's entire or remaining Individual Commitment Amount under the Revolving Facility in accordance with Section 21.2.

2.3              Maturity Date. The Borrower will not be entitled to request a Borrowing under the Revolving Facility from a Revolving Lender which has a Maturity Date after the Revolving Facility Termination Date applicable to such Lender. If, at any time, there are Revolving Lenders with different Revolving Facility Termination Dates, all Revolving Lenders will share in Borrowings under the Revolving Facility on the basis of their Rateable Portions under the Revolving Facility except to the extent that a requested Borrowing has a Maturity Date after the Revolving Facility Termination Date of a Revolving Lender, in which case only those Revolving Lenders with a Revolving Facility Termination Date later than the Maturity Date of the requested Borrowing will be required to participate in providing such Borrowing and the Borrower may request a similar Borrowing to the extent permitted hereunder from the other Revolving Lenders with a Maturity Date occurring on or before the Revolving Facility Termination Date of such Revolving Lenders. Each such determination by the Agent shall be prima facie evidence of such rateable portion or share.

2.4               Mandatory Repayment of Credit Facilities.

(a)      Mandatory Prepayment of Bridge Facility. Within five (5) Banking Days after receipt of any of the net proceeds referred to below, the Borrower will make prepayments of the Principal Amount of the Bridge Facility equal to the amount of:

(i)     after repayment in full of all Senior Unsecured Obligations, the net proceeds (including, without limitation, net of all brokerage commissions, underwriting fees and all reasonable and documented legal and accounting fees and all other customary fees actually incurred in connection therewith) of any indebtedness for borrowed money (which, for certainty, includes any Convertible Debentures) created, issued or incurred by the Borrower or any other Harvest Party, other than (A) indebtedness under this Agreement or the Senior Unsecured Credit Agreement, (B) indebtedness described in paragraphs (a) through (e) of the definition of Consolidated Senior Debt and (C) intercompany indebtedness owed solely to the Borrower or any other Harvest Party;

(ii)     after repayment in full of all Senior Unsecured Obligations, the net proceeds (including, without limitation, net of all brokerage commissions, underwriting fees and all reasonable and documented legal and accounting fees and all other customary fees actually incurred in connection

8

therewith) of any units, shares or other equity or equity-like securities or instruments issued by the Borrower or any other Harvest Party (other than in respect of indebtedness for borrowed money), other than (A) securities or instruments issued solely to the Borrower or any other Harvest Party and (B) securities or instruments of the Trust issued solely in connection with the distribution reinvestment program, the Trust Unit award incentive plan and the Trust Units rights incentive plan of the Trust insofar as each of the same relate to employees, officers or directors of any Harvest Party; and

(iii)     the net cash proceeds (including, without limitation, net of reasonable and documented legal, accounting and investment banking fees, amounts required to be applied to the repayment of any amounts secured by a Permitted Encumbrance on any asset which is the subject of such disposition and other customary fees and expenses actually incurred in connection with the disposition, all net of taxes paid or reasonably expected to be payable as a result of any such disposition) of any sale (including, without limitation, any sale-leaseback), exchange, lease, transfer or other disposition of assets by the Borrower or any other Harvest Party, other than (A) dispositions of Petroleum Substances in the ordinary course of business, (B) dispositions between Harvest Parties, (C) dispositions in the ordinary course of business where the net proceeds of any individual disposition (including any disposition consisting of a series of related transactions) are less than Cdn. $1,000,000 and (D) dispositions where the cumulative net proceeds are less than Cdn. $25,000,000.

The Individual Commitment Amount of each Bridge Lender under the Bridge Facility shall be automatically reduced by such Bridge Lender's Rateable Portion under the Bridge Facility of any net proceeds referred to above which are received prior to the initial Drawdown of the Bridge Facility. The Borrower will provide the Agent with at least two (2) Banking Days' prior written notice of each such prepayment or reduction.

(b)     Bridge Facility Termination Date. The Principal Amount owing to a Bridge Lender, if any, on the Bridge Facility Termination Date of such Bridge Lender will be paid by the Borrower to the Agent on behalf of such Bridge Lender in full, together with all accrued but unpaid interest and fees thereon and all other amounts owing to such Bridge Lender under the Bridge Facility, if any, on such date.

(c)     Revolving Facility Termination Date. The Principal Amount owing to a Revolving Lender, if any, on the Revolving Facility Termination Date of such Revolving Lender will be paid by the Borrower to the Agent on behalf of such Revolving Lender in full, together with all accrued but unpaid interest and fees thereon and all other amounts owing to such Revolving Lender under the Revolving Facility, if any, on such date.

9

2.5              General Right to Prepay and Cancel. Subject to Section 2.2(e) and Section 8.2 and with the same notice required when the Borrowing to be prepaid was made, the Borrower may at any time permanently prepay, without premium, bonus or penalty, any or all of the Aggregate Principal Amount of firstly the Bridge Facility and, after the Bridge Facility has been fully repaid and cancelled, the Revolving Facility, except that a Bankers' Acceptance will not be prepaid prior to its Maturity Date (except the Borrower may provide Escrow Funds therefor in accordance with Section 18.4) and an unexpired Letter of Credit will not be prepaid prior to its Maturity Date (except by the return thereof to the Agent for cancellation or providing Escrow Funds therefor in accordance with Section 18.4). Subject to the preceding sentence and Section 2.2(e), the Borrower may also at any time, upon the Borrower giving the Agent not less than five (5) Banking Days prior notice, cancel in whole or in part any undrawn portion of the Aggregate Commitment Amount under the Revolving Facility, provided that any such cancellation of such Aggregate Commitment Amount will be made pro-rata to all Revolving Lenders on the basis of each such Revolving Lender's Rateable Portion under the Revolving Facility and will result in a permanent reduction of the Aggregate Commitment Amount under the Revolving Facility.

2.6              Payments to Agent. Other than as expressly provided herein, all payments of amounts owing by the Borrower to the Lenders under the Documents will be made by the Borrower to the Agent for the account of the Lenders in accordance with their respective Rateable Portions.

2.7              Use of Proceeds.

(a)      The Borrower will be entitled, subject to Section 6.3, to use Advances under the Revolving Facility for general corporate and trust purposes, including the financing of the NARL Acquisition and other acquisitions.

(b)     The Borrower will be entitled to use the Advance under the Bridge Facility solely for the purpose of financing a portion of the purchase price of the NARL Acquisition.

2.8               Swingline Advances.

(a)      Availability. Notwithstanding Sections 5.2, 5.4, 5.6 and 21.2(a), the Borrower may obtain Swingline Advances under the Revolving Facility in the following manner:

(i)       in the case of Canadian Prime Rate Loans and U.S. Base Rate Loans, on an overdraft basis or by delivering a duly executed Notice of Drawdown to the Swingline Lender (with a copy to the Agent) not later than 11:00 a.m. (Calgary time) on the proposed Drawdown Date;

(ii)     in the case of Bankers' Acceptances, by delivering a duly executed Notice of Drawdown to the Swingline Lender (with a copy to the Agent) not later than 11:00 a.m. (Calgary time) on the proposed Drawdown Date; and

(iii)    in the case of Letters of Credit, by delivering a duly executed Notice of Drawdown to the Swingline Lender at least three (3) Banking Days prior to the proposed Drawdown Date (or such shorter or longer period as may be determined by the Swingline Lender, acting reasonably).

Swingline Advances shall be made solely by the Swingline Lender, without assignment to or participation by other Lenders (except as provided in this Section 2.8). The making of each Swingline Advance shall constitute a Drawdown hereunder and shall reduce the availability of the Revolving Facility by the Principal Amount of such Swingline Advance.

(b)     Individual Limits. Subject to Section 5.7, at no time shall (i) the aggregate Principal Amount of all Swingline Borrowings owing to the Swingline Lender exceed $50,000,000 (or the Canadian Dollar Exchange Equivalent thereof) or (ii) the aggregate Principal Amount of all Swingline Borrowings owing to the Swingline Lender plus such Lender's Rateable Portion of the Aggregate Principal Amount of all Syndicated Borrowings exceed such Lender's Individual Commitment Amount under the Revolving Facility; provided that the Agent shall adjust the Swingline Lender's Rateable Portion of Syndicated Borrowings in accordance with its customary practice if and to the extent required to ensure that, subject to Section 2.8(c), any undrawn availability of Swingline Borrowings is capable of being fully drawn.

(c)    Aggregate Limit. Subject to Section 5.7, at no time shall the aggregate Principal Amount of all Swingline Borrowings plus the Aggregate Principal Amount of all Syndicated Borrowings exceed the Aggregate Commitment Amount under the Revolving Facility.

(d)     Repayment. Each Swingline Borrowing (other than a Letter of Credit) shall be repaid by the Borrower (or Converted into a Syndicated Borrowing in accordance with Section 2.8(h)) within 30 days after the relevant Drawdown Date (in the case of a Canadian Prime Rate Loan or a U.S. Base Rate Loan) or on the maturity date (not to exceed 30 days after the relevant Drawdown Date) selected by the Borrower in the Notice of Drawdown requesting such Swingline Borrowing (in the case of Bankers' Acceptances). Notwithstanding Section 5.2, no notice of repayment shall be required to be given by the Borrower in respect of any such repayment of any Swingline Borrowing nor shall Swingline Borrowings be Rolled Over or Converted except for Conversions into Syndicated Borrowings in accordance with Section 2.8(h).

(e)     Mandatory Repayment. If the Borrower requests a Syndicated Borrowing and the Swingline Lender's Rateable Portion of such Syndicated Borrowing would cause its Rateable Portion of all Syndicated Borrowings then outstanding together with the aggregate Principal Amount of all Swingline Borrowings to exceed the Swingline Lender's Individual Commitment Amount under the Revolving Facility, then the Borrower shall be required to repay such Swingline Borrowings (or to Convert such Swingline Borrowings into a Syndicated Borrowing in

-11-

accordance with Section 2.8(h)) to the extent of such excess on or before the requested date of such Syndicated Borrowing.

(f)      Prepayments. The Borrower may make prepayments of Swingline Borrowings at any time and from time to time without notice or penalty; provided that: (i) any Swingline Borrowing by way of Bankers' Acceptances cannot be prepaid, and (ii) any Swingline Borrowing by way of Letter of Credit may only be prepaid if such Letter of Credit is returned to the Swingline Lender for cancellation, collateralized in accordance with Section 18.4 or converted into a Syndicated Borrowing in accordance with Section 2.8(h).

(g)     Sole Account. All interest payments, acceptance fees and principal repayment of or in respect of Swingline Borrowings shall be solely for the account of the Swingline Lender. Subject to Section 2.8(h), all costs and expenses relating to the Swingline Borrowings shall be solely for the account of the Swingline Lender.

(h)     Conversion to Syndicated Borrowings. Notwithstanding anything to the contrary herein contained, (i) at any time at the option of the Borrower or (ii) if an Event of Default occurs or any Swingline Borrowing is not repaid on its Maturity Date, then the Borrower (in the case of (i) above) shall give notice to the Swingline Lender and the Agent or the Swingline Lender (in the case of (ii) above) shall give notice to the Borrower and the Agent (which notice shall in each case direct a Conversion of such Swingline Borrowing into a Syndicated Borrowing and shall specify the particulars of such Swingline Borrowing), and the Agent shall forthwith provide a copy of such notice to the other Revolving Lenders under the Revolving Facility and, effective on the day of notice to that effect to such other Revolving Lenders from the Borrower or the Swingline Lender, the Borrower shall be deemed to have requested a Conversion of such Swingline Borrowing into an amount of Syndicated Borrowings, in the same type of Borrowing as the relevant Swingline Borrowing, sufficient to repay the relevant Swingline Borrowing and accrued and unpaid interest in respect thereof. Subject to the same notice period set out in Section 5.2, and excluding any Swingline LCs which are to be Converted into Fronted LCs, such other Revolving Lenders shall disburse to the Agent for payment to the Swingline Lender their respective Rateable Portions of such amounts and such amounts shall thereupon be deemed to have been advanced by such other Revolving Lenders to the Borrower and to constitute Syndicated Borrowings by way of Canadian Prime Rate Loans (if the relevant Swingline Borrowing was denominated in Cdn. Dollars) or U.S. Base Rate Loans (if the relevant Swingline Borrowing was denominated in U.S. Dollars). Such Syndicated Borrowings shall be deemed to be comprised of principal and accrued and unpaid interest in the same proportions as the corresponding Swingline Borrowings.

-12-

(i)      Unconditional Obligation. For certainty, it is hereby acknowledged and agreed that the Revolving Lenders shall be obligated to disburse to the Agent for payment to the Swingline Lender their respective Rateable Portions of any Syndicated Borrowings contemplated by Section 2.8(h) regardless of-

(i)      whether a Default or Event of Default has occurred or is then continuing or whether any other condition in Article 6 is met;

(ii)     whether or not the Borrower has, in fact, actually requested such Conversion (by delivery of a Notice of Conversion or otherwise); and

(iii)    whether or not the obligations of the Revolving Lenders to make Advances has terminated.

(j)     Continuing Obligations. Notwithstanding that any Lender may assign its rights and obligations under this Agreement, the obligations in this Section 2.8 shall continue as obligations of the Persons who were Revolving Lenders at the time each such Swingline Advance was made, unless the Swingline Lender specifically releases such Revolving Lender from such obligations in writing.

2.9              Existing Borrowings under Existing Facilities.

(a)      Existing Letters of Credit. At the Effective Time, each Existing LC shall be deemed to be outstanding as a Letter of Credit issued at the request of the Borrower hereunder and shall be deemed to be either a Fronted LC or a Swingline LC as specified in Schedule N. In order to continue each such Existing LC under the Revolving Facility:

(i)      any Revolving Lender that issued such Existing LC will be deemed to be an Issuing Lender with respect to such Existing LC, and each Revolving Lender agrees on a pro rata basis to indemnify such Issuing Lender in accordance with Section 10.4 for all such Existing LCs which are Syndicated Borrowings;

(ii)     if such Existing LC is deemed to be a Swingline Borrowing, the Revolving Lender that issued such Existing LC shall be deemed to be a Swingline Lender; and

(iii)   each Revolving Lender that received Issuance Fees payable in advance with respect to such Existing LC will provide such credits or make such payments as may be required in order to reflect the Rateable Portions under the Revolving Facility (as determined by the Agent in accordance with its customary practice); provided that no such fee adjustment shall be made for (A) any Existing LC issued by National Bank of Canada or (B) any Existing LC issued by CIBC with a Face Amount of less than $1,000,000.

- 13-

(b)     Existing BAs. At the Effective Time, each Existing BA shall be deemed to be outstanding as a Bankers' Acceptance accepted or made hereunder at the request and for the account of the Borrower under the Revolving Facility. In order to continue each such Existing BA under the Revolving Facility, each Revolving Lender that received Stamping Fees payable in advance with respect to such Existing BA shall provide such credits or make such payments as may be required in order to reflect the Rateable Portions under the Revolving Facility (as determined by the Agent in accordance with its customary practice) and each Revolving Lender agrees to indemnify each Revolving Lender that accepted an Existing BA in accordance with such Rateable Portions. In addition, each Revolving Lender acknowledges that the Agent is authorized to enter into the BA Indemnity Agreements for and on behalf of the Revolving Lenders and that such Revolving Lender will be bound by the BA Indemnity Agreements.

(c)     Other Existing Advances. At the Effective Time, each outstanding Advance (other than Existing LCs and Existing BAs) shall be deemed to be outstanding as an Advance hereunder and each Lender agrees to make such adjustments thereto as may be required in order to reflect the new Rateable Partners under the Revolving Facility (as determined by the Agent in accordance with its customary practice).

* Note: For purposes of calculating the Consolidated Senior Debt to EBITDA Ratio in the pricing table above, the definition of "Consolidated Senior Debt" shall be deemed to include all of the Senior Unsecured Obligations outstanding at such time of calculation notwithstanding the fact that such obligations may be unsecured at such time.

** Note: The calculation of the Consolidated Senior Debt to EBITDA Ratio (a) on and at any time after the Closing Date until the last day of the calendar month during which a Compliance Certificate in respect of the fiscal quarter ended September 30, 2006 is delivered in accordance with Section 14.1(b) shall be based upon the pro-forma Compliance Certificate delivered pursuant to Section 6.1(h) and (b) on and after the first day of the calendar month following receipt of the Compliance Certificate referred to in the preceding clause (a) until the last day of the calendar month during which a Compliance Certificate in respect of the fiscal year ended December 31, 2006 is delivered to the Agent in accordance with Section 14.1(b) shall be based upon a pro-forma Compliance Certificate as at September 30, 2006 reflecting the consummation of the NARL Acquisition.

*** Note: The applicable margins for BA Equivalent Advances will be determined in accordance with Section 9.4.

(h)     Change in Rates Due to Change in Ratio. The effective date on which any change in interest rates on Canadian Prime Rate Loans, U.S. Base Rate Loans and LIBOR Based Loans or in Issuance Fees and Standby Fees occurs will be the first day of the calendar month following the date of receipt by the Agent of a Compliance Certificate which evidences a change in the Consolidated Senior Debt to EBITDA Ratio (as modified by the first notation in Section 3.2(g) above); provided that if the Borrower fails to deliver such Compliance Certificate when due in accordance with Section 14.1(b), then the applicable margins shall be based upon Level 6 from such due date until the date of delivery of such Compliance Certificate. Any increase or decrease in the interest rates on LIBOR Based Loans outstanding on the effective date of a change in such ratio will apply proportionately to each such LIBOR Based Loan outstanding on the basis of the number of days remaining in the term to maturity thereof. Any increase or decrease in the Stamping Fees on Bankers' Acceptances outstanding on the effective date of such a change will apply for new Bankers' Acceptances issued after such effective date or on any Rollover of an existing Bankers' Acceptance but otherwise the Stamping Fees on any Bankers' Acceptance existing on such effective date will not change until the maturity date thereof. Any increase or decrease in the Issuance Fees on Letters of Credit outstanding on the effective date of a change in such ratio will apply proportionately to each such Letter of Credit outstanding on the basis of the number of days remaining until the expiry date thereof.

3.3              Fronting Fee. The Borrower will pay to the Agent for distribution to the Issuing Lender, in respect of each Fronted LC issued, to be issued or renewed by the Issuing Lender and as a condition of such issuance or renewal, a non-refundable fronting fee ("Fronting

    -16-

Fee") for the account of the Issuing Lender, in the currency of the Fronted LC calculated, on a basis of the Face Amount and term of the Fronted LC at a rate per annum equal to 12.5 Basis Points.

3.4              Standby Fee. The Borrower will, effective from and including the Closing Date, pay to the Agent for the benefit of the Revolving Lenders a standby fee ("Standby Fee") equal to the applicable rate (expressed as a rate per annum) specified in the pricing table set out in Section 3.2(g), calculated on the basis of a 365 day year and on the Aggregate Commitment Amount under the Revolving Facility less the Canadian Dollar Exchange Equivalent of the Aggregate Principal Amount under the Revolving Facility owing to all Revolving Lenders. The Standby Fee will be calculated daily and will be payable quarterly in arrears on the first Banking Day of each calendar quarter for the previous quarter and otherwise in the same manner as interest on Canadian Prime Rate Loans.

3.5             Agency Fee. The Borrower will pay to the Agent on an annual basis on each anniversary of February 3 the agency fee agreed upon between the Borrower and the Agent, the amount thereof to be kept confidential by the Borrower, subject to the exceptions set forth in Section 19.2.

3.6             Additional Fee. If and for so long as any Senior Unsecured Obligations are outstanding, the Borrower will pay to the Agent for the benefit of all Lenders an additional fee (expressed as a rate per annum) of 0.15%, calculated on the basis of a 365 day year and on the Canadian Dollar Exchange Equivalent of the Aggregate Principal Amount of the Revolving Facility (for the account of the Revolving Lenders) and on the Canadian Dollar Exchange Equivalent of the Aggregate Principal Amount of the Bridge Facility (for the account of the Bridge Lenders). Such additional fee will be calculated daily and will be payable quarterly in arrears on the first Banking Day of each calendar quarter for the previous calendar quarter and otherwise in the same manner as interest on the Canadian Prime Rate Loans.

ARTICLE 4
SECURITY

4.1             Security. All Obligations and the Hedge Indebtedness will be secured by the following security, undertakings and other agreements (such security, undertakings and other agreements and all other or additional security required to be delivered by any Harvest Party from time to time pursuant to this Article 4 are collectively referred to as the "Security"):

The Parties acknowledge that the Existing Security has been delivered to the Agent and that the Existing Security forms part of the Security. In addition, the Borrower hereby covenants and agrees to cause Redearth Partnership to deliver a supplemental debenture to the Agent and the Lenders within 21 days of the Closing Date in order to conform its debenture in the Existing Security to the form of debenture in Schedule F-1 .

4.2               Sharing Security with Hedge Indebtedness.

(a)      The Parties acknowledge and agree that the Security is being held by the Agent to secure the Obligations and the Hedge Indebtedness on a pari passu basis.

(b)     If requested by any of the Agent or any Hedge Lender, then each of the Agent and the Hedge Lenders will enter into such further intercreditor agreements and assurances as may be reasonably requested to further evidence the sharing provisions of this Section 4.2, provided that such intercreditor agreements or assurances shall be consistent with any Intercreditor Agreement which may be from time to time in force or effect and, in the event of any conflict with any Intercreditor Agreement, the provisions of such Intercreditor Agreement shall govern. In addition to the pari passu sharing provisions referred to above, such further agreements shall incorporate the following principles (which will also apply prior to the entering into of such further agreements):

(i)      a Hedge Lender cannot elect to enforce the Security unless the Majority Lenders have elected to enforce the Security in accordance with Section 18.2;

(ii)     any matter or thing done or omitted to be done by a Lender under or in respect of this Agreement, the Security or the other Documents will be binding upon the Hedge Affiliate of such Lender and each Lender does hereby indemnify and save the other Lenders and the Agent harmless from any and all claims, demands or actions that a Hedge Affiliate of such Lender may have against the other Lenders and the Agent for any matter or thing done or omitted to be done by any of them under and in respect of this Agreement, the Security and the other Documents;

(iii)    subject to Section 4.2(b)(i), a Hedge Lender (in such capacity) will under no circumstances be considered to be a Lender for the purposes of this Agreement and will not be entitled to vote or to receive any notices hereunder;

-18-

(iv)    if the Agent accelerates the Obligations pursuant to Section 18.2, each Hedge Lender will promptly take all such steps as may be reasonably required to ensure that a Hedge Crystallization Event occurs in respect of all of its outstanding Lender Hedge Agreements;

(v)    subject to Section 4.10, if any Lender Hedge Agreements remain outstanding after the Obligations are fully paid and satisfied and the Credit Facilities are cancelled, the Agent shall discharge the Security; provided that:

(A)    at the request of any Hedge Lender, but subject to (D) below, the Borrower will promptly enter into margin arrangements with such Hedge Lender which will require the Borrower to promptly provide such Hedge Lender with a pledge of cash or marketable securities with an aggregate value not less than the aggregate Hedge Indebtedness then owing to such Hedge Lender from time to time (to be determined as if a Hedge Crystallization Event had occurred);

(B)    at the request of any Hedge Lender (which request may be made at any time after the Closing Date), but subject to (D) below, the Borrower agrees to amend its ISDA Master Agreement with such Hedge Lender to reflect the provisions of (A) above;

(C)    the provisions in (A) and (B) above shall survive repayment of the Obligations and termination of the Credit Facilities; and

(D)    any Hedge Lender may elect to expressly override the provisions in (A) and (B) above in its ISDA Master Agreement (or in any amendment thereto) by expressly contemplating the discharge of the Security and the consequences thereof; provided that no such election shall affect the rights of any other Hedge Lender.

4.3               Sharing Security with Pari Passu Senior Debt. The Borrower or any other Harvest Party may incur Pari Passu Senior Debt subject to the following conditions:

(a)     at the time of incurrence of such Pari Passu Senior Debt, the Borrower shall be in compliance with the financial covenants in Section 14.3 (as determined by calculating Consolidated Senior Debt and Consolidated Total Debt as at the date of such incurrence and inclusive of such incurrence and by calculating Consolidated EBITDA and Total Capitalization as at the end of the most recent fiscal quarter for which financial statements have been delivered pursuant to Section 14.1(a); provided that if such Pari Passu Senior Debt is incurred to finance an acquisition, the Consolidated EBITDA associated with such acquisition and any unitholders' equity issued in connection with such acquisition will be included on a pro forma basis (in a manner satisfactory to the Majority Lenders acting reasonably) in the calculation of such financial covenants as if

-19-

such acquisition had been made at the beginning of the calculation period for such financial covenants);

(b)     the holder(s) of such Pari Passu Senior Debt shall be required to enter into an Intercreditor Agreement and: (i) if such holder(s) intend to share in the Debenture Security, to obtain unlimited guarantees from each Harvest Party (other than the direct obligor of such Pari Passu Senior Debt), or (ii) if such holder(s) intend to hold their own Pari Passu Security, to obtain such Pari Passu Security;

(c)     except as contemplated in Section 4.3(b), the holder(s) of such Pari Passu Senior Debt shall not have any other Security Interests which secure such Pari Passu Senior Debt;

(d)     if such holder(s) intend to share in the Debenture Security, the Agent in its reasonable discretion may require that the principal amount of the Debenture Security be increased or that the Debenture Security be assigned to and held by a collateral agent (and any such collateral agent must be approved by the Agent and the Borrower); and

(e)     no Default or Event of Default shall have occurred and be continuing at the time of incurrence of such Pari Passu Senior Debt.

4.4              Registration.

(a)     Subject to Section 4.4(b), the Borrower shall, at its expense, register, file or record the Security in all offices where such registration, filing or recording is necessary or of advantage to the creation, perfection and preserving of the security applicable to it. The Borrower shall amend and renew such registrations, filings and recordings from time to time as and when required to keep them in full force and effect or to preserve the Security Interests established by any prior registration, filing or recording thereof. To facilitate such ongoing perfection of the Security, the Borrower shall promptly notify the Agent of (i) any change in the location of its chief executive office from Calgary or (ii) any acquisition by it of any material property or assets located outside of the Provinces of Alberta, Saskatchewan or British Columbia.

(b)     Except for fixed charge registrations of the Security against the Refinery Lands, the Borrower shall not be required to register, file or record the Security at any land titles office or registry against any specific real property interests owned by any Harvest Party unless directed to do so by the Majority Lenders at any time when a Default or an Event of Default has occurred and is continuing.

(c)     The Agent shall have the right to make, at the expense of the Borrower, all such registrations, filings or recordings as are required to be made by the Borrower pursuant to this Section 4.4.

4.5               Exclusivity of Remedies. Nothing herein contained or in the Security now held or hereafter acquired by the Agent or the Lenders nor any act or omission of the Agent or

-20-

the Lenders with respect to any such Security, will in any way prejudice or affect the rights, remedies or powers of the Agent or the Lenders with respect to any other security at any time held by the Agent or the Lenders.

4.6               Form of Security. The Security will be in such form or forms as provided in the Schedules to this Agreement or, where not set out in a Schedule, in such form as required by the Agent, acting reasonably. Subject to Section 4.4(b), if the Majority Lenders determine at any time and from time to time, acting reasonably, that the then existing Security has, for whatever reason, become unenforceable or no longer constitutes legally valid and binding obligations of the Harvest Parties, or the Security or the registration or perfection of the Security Interests constituted by the Security does not fully provide the Lenders with the Security Interests and priority to which the Lenders are entitled or intended to have under the Documents, the applicable Harvest Parties will at the request of the Agent forthwith execute and deliver, or cause to be executed and delivered, to the Agent, at the Borrower's expense, such amendments to the then existing Security or provide such new or replacement Security as the Agent may reasonably request to ensure the Agent holds the Security which it was originally entitled or intended to have under the Documents.

4.7               Permitted Encumbrances. None of the fact that:

(a)     any Harvest Party is permitted to create or suffer to exist any Permitted Encumbrance;

(b)     any representation, warranty or covenant herein may make an exception for the existence of Permitted Encumbrances; or

(c)     the Security Interests created pursuant to the Security are stated to be subject to, or are not required to rank in priority to, Permitted Encumbrances;

shall in any manner, nor in any cause or proceeding, directly or indirectly, be taken to constitute a subordination of any Security Interest created pursuant to the Security to any Permitted Encumbrance or to any other Security Interest or other obligation whatsoever, or that the Obligations are in any way subordinate or junior in right of payment to any other Indebtedness; provided that the Lenders authorize the Agent, upon the request of the Borrower, to subordinate and/or release the Security Interests created by the Security to any Permitted Encumbrance described in paragraph (m) of the definition of Permitted Encumbrances.

4.8             Undertaking to Grant Fixed Charge Security. At the request of the Agent made at any time after a Default or an Event of Default has occurred and is continuing, the Borrower will forthwith grant and cause each other Harvest Party to grant to the Agent a fixed charge in all or any of the Borrower's or any other Harvest Party's material assets.

4.9             Further Assurances. The Borrower will, in connection with the provision of any amended, new or replacement Security referred to in Section 4.6.

-21-

(a)     do, make, execute and deliver, or cause to be done, made, executed and delivered, all such further documents, financing statements, assignments, acts, matters and things which may be reasonably required by the Agent to give effect to any provision of the amended, new or replacement Security;

(b)     provide the Agent with all corporate, partnership or of other organizational resolutions and other action required for the Borrower or any other Harvest Party to grant the amended, new or replacement Security;

(c)     provide the Agent with an opinion of the Borrower's Counsel confirming the due authorization, execution and delivery by the applicable Harvest Parties of all such agreements and instruments comprising the amended, new or replacement Security in form and content satisfactory to the Agent, acting reasonably; and

4.10           Discharge of Security Upon Cancellation of Credit Facilities. Subject to the terms of any Intercreditor Agreement, the Agent will discharge the Security at the Borrower's expense forthwith after all of the Obligations have been unconditionally and irrevocably paid or satisfied in full (with the exception of any indemnity obligations which by their terms survive such payment or satisfaction) and the Aggregate Commitment Amount under each of the Credit Facilities has been cancelled by the Borrower, provided no Claim has at such time been made or threatened by a third-party against the Agent or any Lender with respect to any Credit Facility or the Hedge Agreements and for which there does not exist an adequate indemnity from the Borrower.

Subject to Section 5.2 and Article 8, Article 9 and Article 10, all Advances will be made available by deposit of the applicable funds (which in the case of Bankers' Acceptances will be the Net Proceeds) into the appropriate Borrower's Account for value on the Banking Day or the LIBOR Banking Day, as the case may be, on which the Advance is to take place.

5.2              Notice Provisions.

Any of the notices referred to in the foregoing paragraphs may, subject to Section 22.2, be given by the Borrower, at its sole risk, to the Agent by telephone and in such case will be followed by the Borrower delivering to the Agent on the same day the notice required hereunder confirming such instructions.

5.3              Irrevocability. A Notice of Drawdown, Notice of Rollover or Notice of Conversion when given by the Borrower will be irrevocable and will oblige the Borrower, the Agent and the Lenders under the applicable Credit Facility to take the action contemplated herein and therein on the date specified therein, provided that any such notice will not be binding on any Lender who makes a determination under Section 11.2.

5.4              Rollover or Conversion of Borrowings.

(a)     Subject to Sections 5.2 and 5.4(e) and Article 8, Article 9 and Article 10, the Borrower will be entitled to Rollover one type of Borrowing under a Credit Facility into the same type of Borrowing under the same Credit Facility or Convert one type of Borrowing under a Credit Facility into another type of Borrowing under the same Credit Facility on the terms herein provided.

(b)     If the Borrower fails to give the Agent a duly completed Notice of Rollover or Notice of Conversion if and as required by Section 5.2, or if in giving such notice the Borrower fails to provide for the Rollover or Conversion of all of the

-23-

Borrowings under a Credit Facility then maturing, the Borrower will be deemed to have irrevocably elected to Convert such maturing Borrowings, or that part of such maturing Borrowings which the Borrower has failed to provide for in such notice, as the case may be, into a Canadian Prime Rate Loan with respect to a Cdn. Dollar Borrowing or a U.S. Base Rate Loan with respect to a U.S. Dollar Borrowing in each case under the same Credit Facility.

(c)     No Conversion of a Bankers' Acceptance issued under a Credit Facility will be made prior to the Maturity Date thereof.

(d)     Subject to Section 8.2, the Borrower may elect to Convert a LIBOR Based Loan under a Credit Facility prior to the Maturity Date thereof into another type of Borrowing under the same Credit Facility.

(e)     If a Default or Event of Default has occurred and is continuing, the Borrower will not be entitled to make a Rollover or Conversion and, upon the Maturity Date of the relevant Borrowing, the provisions of Section 5.4(b) will apply.

5.5             Agent's Obligations. Upon receipt of a Notice of Drawdown, Notice of Rollover or Notice of Conversion with respect to a proposed Advance (other than by way of Bankers' Acceptances) under a Credit Facility, the Agent will forthwith notify the Lenders under such Credit Facility of the proposed date on which such Advance is to take place, of each such Lender's Rateable Portion of such Advance and if applicable, of the account of the Agent to which each such Lender's Rateable Portion thereof is to be credited.

5.6              Lenders' Obligations. Each applicable Lender will, prior to 12:00 noon (Toronto, Ontario time) on the proposed date on which an Advance is to take place (other than by way of Bankers' Acceptances), credit the account of the Agent specified in the Agent's notice given pursuant to Section 5.5 with such Lender's Rateable Portion of such Advance, and by 1:00 p.m. (Toronto, Ontario time) on the same date, the Agent will make available to the Borrower the amount so credited.

5.7             Currency Fluctuation. If as a result of currency fluctuation the Canadian Dollar Exchange Equivalent of the Principal Amount owing to a Lender under a Credit Facility exceeds such Lender's Rateable Portion of the Aggregate Commitment Amount under such Credit Facility (the "Excess"), the Borrower will pay the Excess to the Agent as a principal repayment for the benefit of the applicable Lender. If the amount of the Excess with respect to any such Lender is equal to or greater than 3% of such Lender's Rateable Portion of the Aggregate Commitment Amount under such Credit Facility, then the repayment of the Excess to such Lender will be made by the Borrower within 3 Banking Days after the Excess exceeds such threshold. If the amount of the Excess with respect to any such Lender is less than 3% of such Lender's Rateable Portion of the Aggregate Commitment Amount under such Credit Facility, then the repayment of the Excess to such Lender will be made on the earlier of the first Banking Day of the next following month or the next day on which interest is paid on any LIBOR Based Loans or a Stamping Fee is paid with respect to any Bankers' Acceptances. The Agent will request repayment of any Excess forthwith upon request therefor by any Lender, provided that

-24-

the Agent will not otherwise be required to monitor the Excess or to request repayment thereof.

5.8              Excess Relating to LIBOR and BAs. If to pay an Excess, it is necessary to repay a LIBOR Based Loan or a Borrowing by way of Bankers' Acceptances prior to their Maturity Dates, the Borrower will not be required to repay such Borrowing until such Maturity Dates thereof, provided, however, that at the request of the Agent, the Borrower will forthwith pay to the Agent for deposit into an escrow account maintained by and in the name of the Agent for the benefit of the applicable Lenders the Excess, to be held by the Agent for set-off against future amounts owing by the Borrower to the Lenders under the applicable Credit Facility in respect of such Excess and, pending such application, will bear interest for the Borrower's account at the rate declared by the Agent from time to time as that payable by it in respect of deposits for such amount and for the period from the date of deposit to the Maturity Date of such Borrowing.

6.2             Conditions Precedent to all Drawdowns. The Lenders' obligation to provide Advances under any Credit Facility will be subject to and conditional upon the following conditions precedent being met, unless waived in writing by the Lenders under such Credit Facility:

(d)     the notice with respect to a Hostile Acquisition if required to be given pursuant to Section 6.3 will have been provided by the Borrower and the other provisions of Section 6.3, if applicable, will have been complied with.

(a)     at least 10 Banking Days prior to the delivery to the Agent of a Notice of Drawdown made in connection with a Hostile Acquisition, the president or senior financial officer of the Borrower will notify the Agent (who will then notify the Lenders) of the particulars of the Hostile Acquisition in sufficient detail to enable each Revolving Lender to determine, in each Revolving Lender's sole discretion, whether it will participate in a Drawdown to be utilized for such Hostile Acquisition;

-27-

(b)     if a Revolving Lender decides not to fund a Drawdown to be utilized for such Hostile Acquisition, then upon such Revolving Lender so notifying the Agent and the Borrower, such Revolving Lender will have no obligation to fund such Drawdown notwithstanding any other provision of this Agreement to the contrary; and

(c)     each Revolving Lender will use reasonable commercial efforts to notify the Agent as soon as practicable (and in any event within 7 Banking Days of receipt of the particulars thereof from the Agent) of its decision whether or not to fund a proposed Hostile Acquisition.

6.4              Adjustment of Rateable Portion. If a Revolving Lender elects not to participate in a Drawdown for a Hostile Acquisition (a "Non-Participating Lender"), the Drawdown will be reduced by the Non-Participating Lenders' Rateable Portion under the Revolving Facility of such Drawdown and the allocation among all Revolving Lenders of interest and other fees payable to the Revolving Lenders by the Borrower hereunder, including Standby Fees, will be adjusted so as to reflect the reduction in the Drawdown, and thereafter the Rateable Portion of each Lender under the Revolving Facility, for such purposes only, will reflect the Principal Amount then funded by each Revolving Lender based on the Aggregate Principal Amount of all Revolving Lenders under the Revolving Facility after taking into account the amount of the requested Drawdown not funded by the Non-Participating Lender. Notwithstanding the adjustment of the Rateable Portion under the Revolving Facility pursuant to this Section 6.4, there will be no reduction in the Individual Commitment Amount of each Revolving Lender under the Revolving Facility.

6.5             Subsequent Drawdowns. If a Lender becomes a Non-Participating Lender, subsequent Drawdowns will be funded first by the Non-Participating Lender rateably based on each Non-Participating Lender's Individual Commitment Amount under the Revolving Facility, until the Principal Amounts of the Revolving Lenders are again in proportion to their respective Rateable Portions under the Revolving Facility prior to the Hostile Acquisition.

6.6              Prepayment. As an alternative to the provisions of Section 6.5, the Borrower will also be entitled, subject to the prepayment provisions herein contained but without obligation to make prepayments to all Lenders, to reduce the Principal Amount owing to the Revolving Lenders who are not Non-Participating Lenders so that the Principal Amounts of the Revolving Lenders are again in proportion to their respective Rateable Portions under the Revolving Facility prior to the Hostile Acquisition.

ARTICLE 7
CALCULATION OF INTEREST AND FEES

7.1             Records. The Agent will maintain records, in written or electronic form, evidencing all Advances and all other Indebtedness owing by the Borrower to the Agent and each Lender under each Credit Facility and this Agreement. The Agent will enter in such records details of all amounts from time to time owing, paid or prepaid by the Borrower to it hereunder. In addition, each Lender will maintain records, in written and electronic

-28-

form, evidencing all Advances and other Indebtedness owing by the Borrower to such Lender under each Credit Facility and this Agreement. The information entered in such records will constitute prima facie evidence of the Indebtedness of the Borrower to the Agent and each Lender under each Credit Facility and this Agreement. In the event of a conflict between the records of the Agent and a Lender maintained pursuant to this Section 7.1, the records of the Agent will prevail, absent manifest error.

7.2              Payment of Interest and Fees.

(a)     Interest. Except as expressly stated otherwise herein, all Canadian Prime Rate Loans, U.S. Base Rate Loans and LIBOR Based Loans from time to time outstanding under each Credit Facility will bear interest, as well after as before maturity, default and judgment, with interest on overdue interest, at the applicable rates as prescribed under Sections 3.2 and 22.9, as applicable. Interest payable at a variable rate will be adjusted automatically without notice to the Borrower whenever there is a variation in such rate.

(b)     Calculation of Interest. Interest under each Credit Facility on Canadian Prime Rate Loans and U.S. Base Rate Loans will accrue and be calculated daily and be payable monthly in arrears on the first Banking Day of each month for the immediately preceding month, or, after notice to the Borrower, on such other Banking Day as is customary for the Agent having regard to its then existing practice. Interest under each Credit Facility on Canadian Prime Rate Loans and U.S. Base Rate Loans and Stamping Fees under such Credit Facility on Bankers' Acceptances will be calculated on the basis of a 365 day year.

(c)     Interest Act (Canada). For the purposes of the Interest Act (Canada) and all other applicable Laws which may hereafter regulate the calculation or computation of interest on borrowed funds, the annual rates of interest and fees applicable under each Credit Facility to Canadian Prime Rate Loans, U.S. Base Rate Loans and Bankers' Acceptances, respectively, are the rates as determined hereunder multiplied by the actual number of days in a period of one year commencing on the first day of the period for which such interest or stamping fee is payable and divided by 365.

(d)     LIBOR Based Loans. Interest on LIBOR Based Loans under each Credit Facility will accrue and be calculated daily and be payable at the end of each applicable LIBOR Period, provided that, where the LIBOR Period exceeds 90 days, interest will be calculated and payable every 90 days during the term of the LIBOR Period and on the last day of the applicable LIBOR Period. Interest on LIBOR Based Loans will be calculated on the basis of the actual number of days in each LIBOR Period divided by 360. For the purposes of the Interest Act (Canada) and other applicable Laws, the annual rates of interest applicable to LIBOR Based Loans under each Credit Facility are the rates as determined hereunder multiplied by the actual number of days in a period of one year commencing on the first day of the period for which such interest is payable and divided by 360.

-29-

7.3             Calculation and Payment of Stamping Fees. Stamping Fees on Bankers' Acceptances will be calculated on the basis of a year of 365 days. The Borrower will pay to the Agent the applicable Stamping Fees with respect to Bankers' Acceptances on the date of acceptance thereof. Payment of the Stamping Fees may be made by way of set-off as provided in Section 9.3.

7.4              Calculation and Payment of Issuance Fees. Issuance Fees will be calculated on the basis of a year of 365 days and for such period of time as the applicable Letter of Credit remains outstanding. The Issuance Fees will accrue and be calculated daily on the Face Amount of the applicable Letter of Credit and be payable quarterly in arrears on the third Banking Day of each fiscal quarter for the immediately preceding fiscal quarter, or, after notice to the Borrower, on such other Banking Day following any such preceding fiscal quarter as is customary for the Agent having regard to its then existing practice. Notwithstanding the foregoing, the minimum Issuance Fee shall be not less than the minimum flat rate issuance fee set by the Issuing Lender from time to time in accordance with its customary practice for letters of credit issued on behalf of comparable borrowers and, if the minimum issuance fee applies, the Issuance Fee shall be payable in advance at the time of issuance of the applicable Letter of Credit. The minimum issuance fee at the date hereof is Cdn. or U.S. $250.

7.5             Conversion to Another Currency. A Conversion of a Borrowing from one currency to another currency may be made only by the repayment of the existing Borrowing in the same currency as the existing Borrowing and the request of a new Advance in another currency.

7.6              Maximum Rate of Return. Notwithstanding any provision herein to the contrary, in no event will the aggregate "interest" (as defined in section 347 of the Criminal Code (Canada)) payable under this Agreement exceed the maximum effective annual rate of interest on the "credit advanced" (as defined in that section) permitted under that section and, if any payment, collection or demand pursuant to this Agreement in respect of "interest" (as defined in that section) is determined to be contrary to the provisions of that section, such payment, collection or demand will be deemed to have been made by mutual mistake of the Borrower and the applicable Lenders and the amount of such payment or collection will be refunded to the Borrower. For purposes of this Agreement, the effective annual rate of interest will be determined in accordance with generally accepted actuarial practices and principles over the term of each Credit Facility on the basis of annual compounding of the lawfully permitted rate of interest and, in the event of dispute, a certificate of a Fellow of the Canadian Institute of Actuaries appointed by the Agent will be prima facie evidence, for the purposes of such determination.

7.7             Waiver of Judgment Interest Act (Alberta). To the extent permitted by applicable Law, the provisions of the Judgment Interest Act (Alberta) will not apply to the Documents and are hereby expressly waived by the Borrower.

7.8             Deemed Reinvestment Not Applicable. For the purposes of the Interest Act (Canada), the principle of deemed reinvestment of interest will not apply to any interest calculation

-30-

under the Documents, and the rates of interest stipulated in this Agreement are intended to be nominal rates and not effective rates or yields.

ARTICLE 8
GENERAL PROVISIONS RELATING TO LIBOR BASED LOANS

8.1              General.

(a)      The aggregate amount of each Advance by way of a LIBOR Based Loan will be at least U.S. $10,000,000 and in multiples of U.S. $100,000 for any amount in excess thereof.

(b)     If the Borrower requests a Drawdown by way of a LIBOR Based Loan, to Rollover a LIBOR Based Loan or to Convert a Borrowing into a LIBOR Based Loan, the Borrower will specify in its Notice of Drawdown, Notice of Rollover or Notice of Conversion, as applicable, the LIBOR Period (which will begin and end on a LIBOR Banking Day) applicable to such LIBOR Based Loan. Subject to Section 5.4(b), if the Borrower fails, as required hereunder, to select a LIBOR Period for any proposed LIBOR Based Loan, then the applicable LIBOR Period will be approximately one month as determined by the Agent.

(c)     For any amounts owing by the Borrower in respect of any LIBOR Based Loan which is not paid at maturity in accordance with this Agreement will, as and from its Maturity Date, be deemed to be outstanding as a U.S. Base Rate Loan.

8.2              Early Termination of LIBOR Periods. If the Borrower requests, as herein permitted, that a Lender arrange for early termination of any LIBOR Based Loan made under a Credit Facility, the Borrower will pay to the affected Lenders all expenses and out-of- pocket costs incurred by such Lenders as a result of the early termination of the LIBOR Based Loan, including expenses and out-of-pocket costs incurred due to early redemption of offsetting deposits. If in the sole discretion of such Lenders, acting reasonably, any such early termination cannot be effected, the LIBOR Based Loan will not be terminated and the Borrower will continue to pay interest to such Lenders, at the rate per annum applicable to such LIBOR Based Loan for the remainder of the applicable LIBOR Period. A written statement of the Agent as to the amount and nature of such expenses and out- of-pocket costs will be prima facie evidence of the amount thereof.

8.3              Inability to Make LIBOR Based Loans. If, on any date, a Lender determines in good faith (which determination will be conclusive as between the Parties), that its ability to make a requested LIBOR Based Loan has become impracticable, impossible or unlawful, or has been materially adversely affected, because:

(a)     of any change in applicable Laws, or in the interpretation or administration thereof by authorities having jurisdiction in the matter, whether or not having the force of Law;

(b)     of any material adverse change in, or the termination of, the London Interbank Eurodollar Market for Eurodollars; or

-31 -

(c)     there exists no adequate or fair measure to ascertain LIBOR for any LIBOR Period for the LIBOR Based Loan,

then the Lender will give the Borrower and the other Lenders notice thereof and thereupon the Lender will have no further obligation with respect to such LIBOR Based Loan, provided that, the Borrower may elect to Drawdown, Rollover or Convert the amount originally requested by way of such LIBOR Based Loan, into some other type of Borrowing upon compliance with the applicable notice requirements set out herein.

ARTICLE 9
BANKERS' ACCEPTANCES

9.1              General. Each bankers' acceptance draft tendered by the Borrower under a Credit Facility for acceptance by a Lender will be a form acceptable to the accepting Lender and the Advance in respect thereof will be in a Face Amount of not less than $10,000,000 (or $1,000,000 if such Advance is a Swingline Advance) and in multiples of $100,000 for any amounts in excess thereof and will, except in the case of Swingline Advances or where the Borrower will be making its own arrangements to market all of the Bankers' Acceptances which form part of such Advance, have a term of not less than one month and not more than six months, unless otherwise agreed to by all of the Lenders, acting reasonably.

9.2              Terms of Acceptance by the Lenders.

(a)      Power of Attorney. To facilitate the procedures contemplated in this Agreement, the Borrower appoints each Lender from time to time as the attorney-in-fact of the Borrower to execute, endorse and deliver on behalf of the Borrower drafts or depository bills in the form or forms prescribed by such Lender for Bankers' Acceptances denominated in Canadian Dollars (each such executed draft or depository xxxx which has not yet been accepted by a Lender being referred to as a "Draft"). Each Bankers' Acceptance executed and delivered by a Lender on behalf of the Borrower will be as binding upon the Borrower as if it had been executed and delivered by a duly authorized officer of the Borrower. The foregoing appointment will cease to be effective, in respect of any Lender, three Banking Days following receipt by such Lender of a notice from the Borrower revoking such appointment (which notice will be copied to the Agent); provided that any such revocation will not affect Bankers' Acceptances previously executed and delivered by a Lender pursuant to such appointment.

(b)     Payment. The Borrower will provide for payment to the Agent for the benefit of the Lenders of each Bankers' Acceptance at its Maturity Date, either by payment of the Face Amount thereof or, subject to Section 7.3, through the utilization of a Borrowing in accordance with this Agreement, or through a combination thereof. The Borrower waives presentment for payment of Bankers' Acceptances by the Lenders and will not claim from the applicable Lenders any days of grace for the payment of Bankers' Acceptances at their Maturity Date. Any amount owing by the Borrower in respect of any Bankers' Acceptance which is not paid at such

-32-

Maturity Date in accordance with this Agreement, will, as and from its Maturity Date, be deemed to be outstanding as a Canadian Prime Rate Loan.

(c)     No Liability. The Lenders will not be liable for any damage, loss or improper use of any bankers' acceptance draft endorsed in blank except for any loss arising by reason of such Lender failing to use the same standard of care in the custody of such bankers' acceptance drafts as such Lender uses in the custody of its own property of a similar nature.

(d)     Bankers' Acceptances Purchased by Lenders. Subject to Section 9.2(f), where the Borrower so elects in the Notice of Drawdown, Notice of Rollover or Notice of Conversion, all Lenders under the applicable Credit Facility, or those applicable Lenders distinguished as either Schedule I, Schedule II or Schedule III banks (as listed in the Bank Act (Canada)) will purchase Bankers' Acceptances accepted by it for an amount equal to the Discount Proceeds having regard to the Discount Rate applicable to such Lender.

(e)     Marketing of BAs. Where the Borrower so elects in the Notice of Drawdown, Notice of Rollover or Notice of Conversion or Section 9.2(f) applies, the Borrower will be responsible for, and will make its own arrangements with respect to, the sale of Bankers' Acceptances in the marketplace. Notwithstanding the foregoing, a Lender may purchase from the Borrower for its own account any Bankers' Acceptance issued by it at the applicable Discount Rate.

(f)     Non-Standard BAs. Notwithstanding the minimum and maximum terms set out in Section 9.1, the Borrower may tender Bankers' Acceptances for acceptance by the Lenders under the applicable Credit Facility of terms that are less than one month, are greater than six months or are for any other non-standard term for which CDOR Rate quotes are not readily available provided that the Borrower may not elect pursuant to Section 9.2(d) that such Lenders purchase such Bankers' Acceptances.

(g)     Depository Bills. It is the intention of the Parties that pursuant to the Depository Bills and Notes Act (Canada) ("DBNA"), all Bankers' Acceptances accepted by the Lenders under this Agreement will be issued in the form of a "depository xxxx" (as defined in the DBNA), deposited with a "clearing house" (as defined in the DBNA), including The Canadian Depository for Securities Ltd. or its nominee CDS & Co. ("CDS"). In order to give effect to the foregoing, the Agent will, subject to the approval of the Borrower and the Lenders, establish and notify the Borrower and the Lenders of any additional procedures, consistent with the terms of this Agreement, as are reasonably necessary to accomplish such intention, including:

(i)     any instrument held by the Agent for purposes of Bankers' Acceptances will have marked prominently and legibly on its face and within its text, at or before the time of issue, the words "This is a depository xxxx subject to the Depository Bills and Notes Act (Canada)";

-33-

(ii)     any reference to the authentication of the Bankers' Acceptance will be removed; and

(iii)    any reference to the "bearer" will be removed and such Bankers' Acceptances will not be marked with any words prohibiting negotiation, transfer or assignment of it or of an interest in it.

9.3                General Mechanics.

(a)     Notice. The Borrower may in the Notice of Drawdown, Notice of Rollover or Notice of Conversion requesting an Advance by way of Bankers' Acceptances or by subsequent notice to the Agent, provide the Agent with information as to the Discount Proceeds payable by the purchasers of the Bankers' Acceptances and the party to whom delivery of the Bankers' Acceptances is to be made against delivery of such Discount Proceeds to the Agent for the credit of the Borrower subject to Section 9.3(c), but if it does not do so, the Borrower will initiate a telephone call to the Agent by 11:00 a.m. (Toronto, Ontario time) on the Drawdown Date or the date of the Rollover or Conversion, as applicable, and provide such information to the Agent. Any such telephone advice will be at the risk of the Borrower pursuant to Section 22.2 and will be confirmed by a notice of the Borrower to the Agent prior to 3:00 p.m. (Toronto, Ontario time) on the same day.

(b)     Rollovers. In the case of a Rollover of maturing Bankers' Acceptances, each Lender under the applicable Credit Facility, in order to satisfy the continuing liability of the Borrower to each such Lender for the Face Amount of the maturing Bankers' Acceptances, will retain for its own account the Net Proceeds of each new Bankers' Acceptance issued by it in connection with such Rollover and the Borrower will, on the Maturity Date of the maturing Bankers' Acceptances, pay to the Agent for the benefit of each such Lender an amount equal to the difference between the Face Amount of the maturing Bankers' Acceptances and the aggregate Net Proceeds of the new Bankers' Acceptances.

(c)     Conversion from Canadian Prime Rate Loans. In the case of a Conversion from a Canadian Prime Rate Loan into a Borrowing by way of Bankers' Acceptances, each Lender under the applicable Credit Facility, in order to satisfy the continuing liability of the Borrower to each such Lender for the principal amount of the Canadian Prime Rate Loan being Converted, will retain for its own account the Net Proceeds of each new Bankers' Acceptance issued by it in connection with such Conversion and the Borrower will, on the date of issuance of the Bankers' Acceptances pay to the Agent for the benefit of each such Lender an amount equal to the difference between the principal amount of the Canadian Prime Rate Loan being Converted, including any accrued interest thereon, owing to each such Lender and the aggregate Net Proceeds of such Bankers' Acceptances.

(d)     Conversion to Canadian Prime Rate Loans. In the case of a Conversion of a Borrowing by way of Bankers' Acceptances into a Canadian Prime Rate Loan, in

-34-

order to satisfy the liability of the Borrower to each Lender under the applicable Credit Facility for the Face Amount of the maturing Bankers' Acceptances, the Agent will record the obligation of the Borrower to it as a Canadian Prime Rate Loan unless the Borrower provides for payment to the Agent for the benefit of each such Lender of the Face Amount of the maturing Bankers' Acceptances in some other manner acceptable to each such Lender.

(e)     Authorization. The Borrower hereby authorizes each Lender under a Credit Facility to complete, stamp, hold, sell, rediscount or otherwise dispose of all Bankers' Acceptances accepted by it pursuant to this Section 9.3 in accordance with the instructions provided by the Borrower pursuant to Section 5.2 or Section 5.4, as applicable.

9.4             BA Equivalent Advance. Each Non-BA Lender, in lieu of accepting bankers acceptance drafts on any Drawdown Date or date of any Conversion or Rollover, will make a BA Equivalent Advance. Any BA Equivalent Advance will be made on the relevant Drawdown Date, or any date of Rollover or Conversion, as applicable, and its Maturity Date will be the Maturity Date of the corresponding Bankers' Acceptances. The amount of each BA Equivalent Advance will be equal to the Discount Proceeds (with reference to the applicable Discount Rate) which would be realized from a hypothetical sale of those Bankers' Acceptances which, but for this Section 9.4, such Lender would otherwise be required to accept (as though such Lender was listed on Schedule II or Schedule III of the Bank Act (Canada)). Any BA Equivalent Advance will be made on the relevant Drawdown Date or date of any Conversion or Rollover, and will remain outstanding for the term of the corresponding Bankers' Acceptances. On its Maturity Date, such BA Equivalent Advance will be repaid in an amount equal to the Face Amount of a Draft that would have been accepted by such Non-BA Lender if it was a BA Lender. All provisions of this Agreement with respect to Bankers' Acceptances will apply to BA Equivalent Advances provided that Stamping Fees with respect to a BA Equivalent Advances will be calculated on the basis of the amount with respect to such BA Equivalent Advances which the Borrower is required to pay on the applicable Maturity Date.

9.5             Execution of Bankers' Acceptances. Subject to Section 9.2(a), the signatures of any authorized signatory on Bankers' Acceptances may, at the option of the Borrower, be reproduced in facsimile and such Bankers' Acceptances bearing such facsimile signatures will be binding on the Borrower as if they had been manually signed by such authorized signatory. Notwithstanding that any person whose signature appears on any Bankers' Acceptance as a signatory may no longer be an authorized signatory of the Borrower at the date of issuance of a Bankers' Acceptance, and notwithstanding that the signature affixed may be a reproduction only, such signature will nevertheless be valid and sufficient for all purposes as if such authority had remained in force at the time of such issuance and as if such signature had been manually applied, and any such Bankers' Acceptance so signed will, subject to Section 9.2(c), be binding on and at the risk of the Borrower.

ARTICLE 10
LETTERS OF CREDIT

10.1         Letters of Credit.

(a)     Letters of Credit. The Borrower will be entitled from time to time, subject to the terms and conditions of this Agreement, to request that Letters of Credit be issued under the Revolving Facility in such form as may be approved by the Issuing Lender, acting reasonably. Fronted LCs will be issued by the Issuing Lender for the account of the Borrower on any Banking Day on behalf of the Revolving Lenders in proportion to their Rateable Portions under the Revolving Facility and in reliance on the agreements of the other Revolving Lenders under the Revolving Facility set forth in Section 10.4(a); provided however, that no Letter of Credit issued under the Revolving Credit Facility will have a Maturity Date beyond the Revolving Facility Termination Date applicable to the Issuing Lender.

(b)     Letter of Credit Maximum Amounts. Notwithstanding the Aggregate Commitment Amount under the Revolving Facility, the limit on Swingline Borrowings or anything else set forth herein:

(i)     the Face Amount of all outstanding Fronted LCs will at no time exceed, in the aggregate, $50,000,000 (or the Canadian Dollar Exchange Equivalent thereof); and

(ii)     the Face Amount of all outstanding Swingline Ls will at no time exceed, in the aggregate, $5,000,000 (or the Canadian Dollar Exchange Equivalent thereof) plus, prior to the replacement thereof, the Face Amount of all Existing LCs deemed to be outstanding as Swingline LCs pursuant to Section 2.9.

(c)     Term and Currency. No Letter of Credit shall be issued under the Revolving Facility (or shall be renewable at the option of the beneficiary of such Letter of Credit) for a term in excess of one year (or such longer period as may be agreed to by the Majority Lenders, acting reasonably), or shall require payment in any currency other than Canadian Dollars or U.S. Dollars. Every Letter of Credit, which by its terms is automatically renewable for a given period of time, which in any event will be for a term of not more than one year (or such longer period as may be agreed to by the Majority Lenders, acting reasonably), will provide that notice from the Issuing Lender can be given to the beneficiary thereof that such Letter of Credit will not be renewed at its Maturity Date upon 30 days prior notice. Notwithstanding the foregoing, if any obligations under any Letter of Credit, whether or not then due and payable, will for any reason be outstanding on the Revolving Facility Termination Date for the Issuing Lender, the Borrower will (i) provide cash collateral therefor in the same manner as provided in Section 18.4 or (ii) cause all such Letters of Credit to be cancelled and returned.

-36-

(d)     Fees. As a condition of the issuance of any Letter of Credit under the Revolving Facility, the Borrower shall pay to the Agent (i) in the case of a Fronted LC only, for the account of the Issuing Lender, the Fronting Fee specified in Section 3.3 and, for the rateable account of the Revolving Lenders, the Issuance Fee specified in Section 3.2(e) or 3.2(f), as applicable and (ii) in the case of a Swingline LC only, for the account of the Issuing Lender, the Issuance Fee specified in Section 3.2(e) or 3.2(f), as applicable. The Borrower will also pay to the Issuing Lender its customary cable charges and other administrative charges in respect of the issuance of Letters of Credit, the amendment or transfer of Letters of Credit and each drawing made under a Letter of Credit.

(e)     Indemnity. Each Revolving Lender, on a several and not a joint and several basis, based on each Revolving Lender's Rateable Portion under the Revolving Facility, hereby indemnifies and holds harmless the Issuing Lender, its Affiliates, shareholders, directors, officers, employees, counsel and agents for any Claims whatsoever (including any reasonable costs or expenses of defending or denying the same) suffered or incurred such Persons, arising out of or in respect of the issuance by the Issuing Lender of Letters of Credit, except for any Claims caused by the Issuing Lender's gross negligence or wilful misconduct.

10.2         Procedure for Issuance of Letters of Credit.

(a)     The Borrower may from time to time request that the Issuing Lender issue or renew a Letter of Credit by delivering to the Agent (and, if applicable, the Swingline Lender) at it address for notice specified herein, and with the same notice period required for a Notice of Drawdown or Notice of Rollover, as the case may be, in respect of an Advance by way of a Letter of Credit in accordance with Section 5.2(d), an application form (an "L/C Application") completed to the satisfaction of the Issuing Lender, acting reasonably, and such other certificates, documents and other papers and information as may be customary and as the Issuing Lender or the Agent may reasonable request.

(b)     At the option of the Borrower, each Letter of Credit may be issued as either a Fronted LC or a Swingline LC. Each Letter of Credit shall be substantially in the Issuing Lender's standard form with modifications thereto consistent with the provisions hereof, or in the case of Letters of Credit issued in favour of the Government of Canada or any province or territory thereof or any agency thereof, in such form as is requested by such Administrative Body and agreed to by the Issuing Lender, acting reasonably, and in each case with any changes to such form requested by the Borrower acting reasonably as (i) the Issuing Lender will determine in good faith and on a commercially reasonable basis does not materially increase the obligations, or diminish the rights, of any Revolving Lender relative to such form or (ii) the Issuing Lender and the Majority Lenders, each acting reasonably, will approve.

(c)     Upon receipt of any L/C Application: (i) the Issuing Lender or the Swingline Lender, as applicable, will process such L/C Application and the certificates,

-37-

documents and other papers and information delivered to it in connection therewith in accordance with its customary procedures; (ii) in the case of a Fronted LC, the Agent will notify each Revolving Lender thereof, which notice shall also specify each Revolving Lender's share of the amount of such Letter of Credit based upon such Lender's Rateable Portion under the Revolving Credit Facility; and (iii) unless such Letter of Credit is, by its terms, automatically renewable, the Issuing Lender will promptly issue or renew the Letter of Credit requested thereby (but in no event will the Issuing Lender be required to issue or renew any Letter of Credit earlier than three Banking Days after its receipt of a Notice of Drawdown or Notice of Rollover in respect of the Letter of Credit to be issued or renewed, as the case may be) by issuing the original of such Letter of Credit to the beneficiary thereof or as otherwise may be agreed by the Issuing Lender and the Borrower. The Issuing Lender will furnish a copy of such Letter of Credit to the Borrower and the Agent promptly following the issuance or renewal thereof.

10.3           L/C Applications. To the extent that any provision of any L/C Application, including any reimbursement provisions contained therein, related to any Letter of Credit is inconsistent with the provisions of this Agreement, the provisions of this Agreement will prevail.

10.4         L/C Participations.

(a)     Effective on the date of issuance of each Fronted LC issued after the Closing Date, the Issuing Lender irrevocably agrees to grant and hereby grants to each Revolving Lender, and each such Revolving Lender irrevocably agrees to accept and purchase and hereby accepts and purchases from the Issuing Lender, on the terms and conditions hereinafter stated and, for such Revolving Lender's own account and risk an undivided interest equal to such Revolving Lender's Rateable Portion under the Revolving Facility in the Issuing Lender's obligations and rights under each Fronted LC issued by the Issuing Lender and the amount of each draft paid by the Issuing Lender thereunder. Each such Revolving Lender unconditionally and irrevocably agrees with the Issuing Lender that, if an amount is paid under any Fronted LC for which such Issuing Lender is not reimbursed in full by the Borrower in accordance with the terms of this Agreement, such Revolving Lender will pay to the Agent, for the account of the Issuing Lender, upon demand at the Agent's address specified herein, an amount equal to such Revolving Lender's Rateable Portion under the Revolving Facility of such amount, or any part thereof, which is not so reimbursed. On the date that any assignee becomes a Revolving Lender party to this Agreement in accordance with Article 20, participating interests in any outstanding Fronted LC, held by the assignor Revolving Lender from which such assignee acquired its interest hereunder will be proportionately reallocated between such assignee and such assignor Revolving Lender. Each Revolving Lender hereby agrees that its obligation to participate in each Fronted LC, and to pay or to reimburse the Issuing Lender or its participating share of the amounts drawn or amounts otherwise paid thereunder, is absolute, irrevocable and unconditional and will not

-38-

be affected by any circumstances whatsoever (including the occurrence or continuance of any Default or Event of Default), and that each such payment will be made without offset, abatement, withholding or other reduction whatsoever.

(b)     If any amount required to be paid by any Revolving Lender to the Issuing Lender pursuant to Section 10.4(a) in respect of any unreimbursed portion of any amount paid by the Issuing Lender under any Fronted LC is paid to the Issuing Lender within three Banking Days after the date such amount is due, such Revolving Lender will pay to the Agent, for the account of the Issuing Lender, on demand, an amount equal to the product of (i) such amount multiplied by (ii) the rate of interest applicable to such amount incurred by the Issuing Lender during the period from and including the date such amount payable under any Fronted LC is paid to the date on which such amount owed by the Revolving Lender to the Issuing Lender immediately available to the Issuing Lender, multiplied by (iii) a fraction the numerator of which is the number of days that elapse during such period and the denominator of which is 365. If any such amount required to be paid by any Revolving Lender pursuant to Section 10.4(a) is not in fact made available to the Agent, for the account of the Issuing Lender, by such Revolving Lender within three Banking Days after the date such payment is due, the Issuing Lender will be entitled to recover from such Revolving Lender, on demand, such amount with interest thereon calculated from such due date at the rate per annum applicable to Canadian Prime Rate Loans or U.S. Base Rate Loans hereunder depending on whether the amount to be paid under such Fronted LC is in Canadian Dollars or U.S. Dollars. A certificate of the Issuing Lender submitted to any Revolving Lender with respect to any amounts owing under this Section 10.4 will be conclusive in the absence of manifest error.

(c)     Whenever, at, any time after the Issuing Lender has paid an amount under any Fronted LC and has received from any Revolving Lender that Lender's Rateable Portion under the Revolving Facility of such payment in accordance with Section 10.4(a), the Issuing Lender receives any reimbursement on account of such unreimbursed portion, or any payment of interest on account thereof, the Issuing Lender will pay to the Agent, for the account of such Revolving Lender that Revolving Lender's Rateable Portion under the Revolving Facility thereof; provided, however, that in the event that any such a payment received by the Issuing Lender is required to be returned by the Issuing Lender, such Revolving Lender will return to the Agent for the account of the Issuing Lender the portion thereof previously distributed to it.

10.5           Reimbursement Obligation of the Borrower. If demand of payment (which may include a draft) is made under any Letter of Credit, the Issuing Lender will notify the Borrower and the Agent of the date and the amount thereof and the Agent, will likewise notify the other Revolving Lenders. The Borrower agrees to reimburse the Issuing Lender for the benefit of the Revolving Lenders, on each date on which the Issuing Lender pays an amount pursuant to such a demand of payment under any Letter of Credit for the amount of (a) such amount so paid, and (b) any Taxes, fees, charges or other costs or expenses reasonably incurred by the Issuing Lender connection with such payment,

-39-

failing which the payment by the Issuing Lender of such drawing on such Letter of Credit shall constitute the making of a Canadian Prime Rate Loan or a U.S. Base Rate Loan as provided below. Each such payment will be made to the Issuing Lender in the same currency as the amount paid by the Issuing Lender and in immediately available funds. If the Borrower does not make any payment required by the preceding sentence from the proceeds of Advances obtained hereunder or otherwise, the Agent will, without receipt of a Notice of Drawdown and irrespective of whether any other applicable conditions precedent specified herein have been satisfied, make a Canadian Prime Rate Loan where the currency of such required payment is Canadian Dollars, or a U.S. Base Rate Loan where the currency of such required payment is in U.S. Dollars, to the Borrower in the aggregate amount of such required payment, and will forthwith give notice thereof to the Borrower and the Revolving Lenders. The Borrower agrees to accept each such Advance and hereby irrevocably authorizes and directs the Agent and the Revolving Lenders to apply the proceeds thereof in payment of the liability of the Borrower with respect to such required payment.

10.6           Obligations Absolute. Subject to the last two sentences of this Section 10.6, the Borrower's obligations with respect to Letters of Credit under this Article 10 will be absolute and unconditional under any and all circumstances and irrespective of any set' off, counterclaim or defence to payment which the Borrower or any other Person may have or have had against the Issuing Lender or any other Revolving Lender or beneficiary of a Letter of Credit. The Borrower also agrees with the Issuing Lender that the Agent, the Revolving Lenders or the Issuing Lender will not be responsible for, and the Borrower's obligations under Section 10.5 will not be affected by, among other things, any dispute between or among the Borrower and any beneficiary of any Letter of Credit or any other Person to which such Letter of Credit may be transferred or any claims whatsoever of the Borrower against any beneficiary of such Letter of Credit or any such transferee; any matter referred to in Section 10.7; any invalidity of any obligation secured by any Letter of Credit; or any incapacity, disability or lack or limitation of status or of power of the Borrower or any beneficiary of any Letter of Credit. The responsibility of the Issuing Lender to the Borrower in connection with any demand of payment (which may include a draft) made under any Letter of Credit will, in addition to any payment obligation expressly provided for in such Letter of Credit, be limited to determining that the documents (including each draft) delivered under such Letter of Credit in connection with such presentment are in conformity with such Letter of Credit. Any action taken or omitted by the Issuing Lender under or in connection with any Letter of Credit or the related drafts or documents, if done in the absence of gross negligence or wilful misconduct and in accordance with applicable Law, will be binding on the Borrower and will not result in any liability of the Issuing Lender to the Borrower.

10.7             No Liability. The Borrower agrees that, other than to the extent provided in the last two sentences of Section 10.6, neither the Agent nor any Revolving Lender, including the Issuing Lender nor any of their respective officers, directors, employees or correspondents will assume liability for, or be responsible for:

(a)     the use which may be made of any Letter of Credit;

-40-

(b)     any acts or omissions of the beneficiary of any Letter of Credit including the application of any payment made to such beneficiary;

(c)     the validity, correctness, genuineness or legal effect of any document or instrument relating to any Letter of Credit, even if such document or instrument should in fact prove to be in any respect invalid, insufficient, inaccurate, fraudulent or forged;

(d)     payment by the Issuing Lender of any draft which does not comply with the terms of any Letter of Credit, unless such payment is not made in good faith or results from the gross negligence or wilful misconduct of the Issuing Lender;

(e)     the failure of any document or instrument to bear any reference or adequate reference to any Letter of Credit;

(f)     any failure to note the amount of any draft on any Letter of Credit or on any related document or instrument; any failure of the beneficiary of any Letter of Credit to meet the obligations of such beneficiary to either the Borrower or any other Person;

(g)     any errors, inaccuracies, omissions, interruptions or delays in transmission or delivery of any messages, directions or correspondence by mail, facsimile or otherwise, whether or not they are in cipher;

(h)     any inaccuracies in the translation of any messages, directions or correspondence or for errors in the interpretation of any technical terms; or

(i)     any failure by the Issuing Lender to make payment under any Letter of Credit as a result of any law, control or restriction rightfully or wrongfully exercised or imposed by any domestic or foreign Administrative Body or as a result of any other cause beyond the control of the Issuing Lender or its respective officers, directors, employees or correspondents.

10.8            Records. The Issuing Lender shall maintain records evidencing the undrawn and unexpired amount of each Letter of Credit issued or renewed by it outstanding hereunder and each Revolving Lender's share of such amount and evidencing for each Letter of Credit issued or renewed hereunder:

(a)     the dates of issuance or renewal and expiration thereof;

(b)     the amount thereof; and

(c)     the date and amount of all payments made thereunder.

The Issuing Lender shall make copies of such records available to the Borrower, the Agent or any Revolving Lender upon its reasonable request.

-41-

10.9            Uniform Customs. Each Letter of Credit, except as specifically provided therein or as agreed to by the Issuing Lender as permitted herein, and subject to any provision hereof to the contrary, will be subject to the Uniform Customs and Practice for Documentary Credits of the International Chamber of Commerce current at the time of issuance or renewal of such Letter of Credit.

ARTICLE 11
INCREASED COSTS

11.1             Changes in Law.

(a)     If, after the date hereof, due to either:

(i)       the introduction of, or any change in, or in the interpretation of any Law, whether having the force of law or not, resulting in the imposition or increase of reserves, deposits or similar requirements by any central bank or Administrative Body charged with the administration thereof; or

(ii)     the compliance with any guideline or request from any central bank or other Administrative Body which a Lender, acting reasonably, determines that it is required to comply with,

there will be any increase in the cost to such Lender of agreeing to make or making, funding or maintaining a Credit Facility, or there will be any reduction in the effective return to such Lender thereunder, then, subject to Section 11.1(b), the Borrower will, within 5 Banking Days after being notified by such Lender of such event, pay to such Lender quarterly in arrears, that amount (the "Additional Compensation") which such Lender, acting reasonably, determines will compensate it, after taking into account all applicable Taxes, for any such increased costs or reduced returns incurred or suffered by such Lender.

(b)     If Additional Compensation is payable pursuant to Section 11.1(a), the Borrower will have the option to prepay any amount of the Credit Facilities owed to the Lender entitled to receive the Additional Compensation, subject always to Section 8.2, without obligation to make a corresponding prepayment to any other Lender. If the Additional Compensation relates to outstanding Bankers' Acceptances under a Credit Facility, such Lender may require the Borrower to deposit in an interest bearing cash collateral account with such Lender such amount as may be necessary to fully satisfy the contingent obligations of such Lender for all outstanding Bankers' Acceptances in accordance with the arrangements set out in Section 18.4.

11.2           Changes in Circumstances. Notwithstanding anything to the contrary herein or in any of the other Documents contained, if on any date a Lender determines in good faith, which determination will be conclusive and binding on the Parties, and provided notice is given to the other Lenders and to the Borrower that its ability to maintain, or continue to offer any Borrowing has become unlawful or impossible due to:

-42-

(a)     any change in applicable Laws, or in the interpretation or administration thereof by authorities having jurisdiction in the matter; or

(b)     any material adverse change in or the termination of the London Interbank Eurodollar Market for Eurodollars; or

(c)     the imposition of any condition, restriction or limitation upon such Lender which is outside of its control,

then in any such case, the Borrower will forthwith repay to such Lender all principal amounts affected thereby, together with all unpaid interest accrued thereon to the date of repayment and all other expenses incurred in connection with the termination of any such Borrowing, including any expenses resulting from the early termination of any LIBOR Period relating thereto in accordance with Section 8.2, without any obligation to make a corresponding prepayment to any other Lender. The Borrower may utilize other forms of Borrowings not so affected in order to make any required repayment and after any such repayment, the Borrower may elect to re-borrow the amount repaid by way of some other Borrowing upon complying with applicable requirements thereof.

11.3             Application of Sections 11.1 and 11.2. If a Lender exercises its discretion under either Section 11.1 or 11.2, then concurrently with a notice from such Lender to the other Lenders and the Borrower requiring compliance with the applicable Section, such Lender will provide the Borrower (with a copy to the other Lenders) with a certificate in reasonable detail outlining the particulars giving rise to such notice, confirming that its actions are consistent with actions concurrently taken by such Lender with respect to similar type provisions affecting other borrowers of such Lender in comparable circumstances and certifying (with reasonable supporting detail) the increased costs, if any, payable by the Borrower thereunder, which will be prima facie proof thereof and binding on the Parties.

11.4            Limitations on Additional Compensation. Sections 11.1 and 11.2 will not apply to a Lender with respect to any event, circumstance or change of the nature and kind of which such Lender had actual knowledge on the Closing Date. A Lender will not be entitled to Additional Compensation to the extent such increase in costs or reduction in return is reflected in or recovered by an increase in the interest or other amounts payable hereunder (other than pursuant to Section 11.1) or relates to any period which is more than three months prior to such Lender becoming aware such Additional Compensation was owing or if such Lender is not generally collecting amounts which are the equivalent to Additional Compensation from other borrowers in similar circumstances to the Borrower where it is contractually entitled to do so.

ARTICLE 12
EXPENSES

12.1           Expenses. The Borrower will pay or reimburse the Agent and the Lenders, as applicable, for the out-of-pocket expenses, including environmental risk assessments, reasonable legal fees (on a solicitor and his own client fully indemnity basis) and disbursements, and

-43-

enforcement costs, incurred by the Agent and the Lenders, as applicable, in connection with the negotiation, preparation, execution, syndication and maintenance of the Documents and the enforcement of their rights and remedies under the Documents.

(b)    Authorization and Status of Agreements.

(i)     the constating documents or by-laws of, or any resolution of the directors, the trustee or partners, as the case may be, of any Harvest Party;

(ii)     the Material Contracts, or any other agreement or document to which any Harvest Party is a party or by which any Harvest Party's property is bound, and which is material to the Harvest Parties taken as a whole; or

There are no actions, suits or proceedings at Law or before or by any Administrative Body existing or pending, or to the Borrower's knowledge threatened, to which any of the Harvest Parties is, or to the Borrower's knowledge is threatened to be made, a party, the result of which would reasonably be expected, if successful against such party, to have a Material Adverse Effect except for the lawsuit described in Schedule 5.9 of the NARL Purchase Agreement.

-45-

Parties have been drilled, completed, shut-in and abandoned (and they have abandoned such xxxxx if they were required by applicable law to have been abandoned), and all property owned or operated by the Harvest Parties has been and will continue to be owned, operated and maintained, as the case may be, in a good and workmanlike manner in accordance with sound industry practice and in accordance with all applicable Laws, except to the extent that the failure to do so would not reasonably be expected to have a Material Adverse Effect.

-46-

case, been obtained and are in good standing, except to the extent that failure to so obtain would not reasonably be expected to have a Material Adverse Effect.

(o)     Pension. Each Harvest Party has in all respects complied with the contractual provisions and applicable Laws relating to each Pension Plan to which it is a party or by which it is otherwise bound, except to the extent failure to comply would not reasonably be expected to have a Material Adverse Effect.

13.2            Acknowledgement. The Borrower acknowledges that the Lenders are relying upon the representations and warranties in this Article 13 in making the Credit Facilities available to the Borrower and that each such representation and warranty (other than that made in

-47-

Section 13.1(j) which will not be restated and that made in Section 13.1(n) which will be restated as of the date referred to therein) will be deemed to be restated in every respect effective on the date each and every Advance is made under the Credit Facilities except for Advances which are Rollovers or Conversions in which case only Section 13.1(1) will be deemed to be restated.

(q)     Enforcement of Security. If any holder of Pari Passu Senior Debt commences enforcement proceedings in respect of the Security in accordance with and as permitted by the Intercreditor Agreement.

(r)     Senior Unsecured Credit Agreement. If an "Event of Default" occurs under and as defined in the Senior Unsecured Credit Agreement.

18.2            Remedies. Upon the occurrence of an Event of Default, the Lenders may forthwith terminate any further obligation to make Advances and the Majority Lenders, through the Agent, may declare all Obligations to be immediately due and payable, whereupon the Borrower will be obligated without any further grace period to forthwith pay such amounts and the Agent and the Lenders may, subject to Sections 21.11 and 22.11, exercise any and all rights, remedies, powers and privileges afforded by the Security or applicable Law or under any and all other instruments, documents and agreements made to assure payment and performance of the obligations of the Borrower under the Documents.

18.3           Waivers. An Event of Default may be waived by the Majority Lenders, except that an Event of Default set forth in Section 18.1(e), 18.1(f) or 18.1(i) may only be waived by all of the Lenders.

18.4           Escrow Funds. Upon the occurrence of an Event of Default, after a domestic or foreign court issues any judgment or order restricting or prohibiting payment by the Issuing Lender under a Letter of Credit or extending the liability of the Issuing Lender to make payment under a Letter of Credit beyond the expiry date specified therein, or if otherwise specifically required pursuant to this Agreement, the Borrower will forthwith pay to (a) the Agent for deposit into a collateral account maintained for the benefit of the Lenders, the Issuing Lender or any Non-Extending Lender, as applicable, an amount equal to such Lender(s)' maximum potential liability under then outstanding Bankers' Acceptances and Letters of Credit (the "Escrow Funds"). The Escrow Funds will be held by the Agent for set-off against future indebtedness owing by the Borrower to the Lenders, the Issuing Lender or any Non-Extending Lender, as applicable, in respect of such Bankers' Acceptances or Letters of Credit, and pending such application will bear interest at the rate payable by the Agent from time to time generally in respect of deposits for such amount, and for the period from the date of deposit to the earlier of the date of release thereof and the Maturity Date of the Bankers' Acceptances or the expiry of the Letters of Credit. If such Event of Default is either waived or cured in compliance with the terms of this Agreement, then the remaining Escrow Funds, if any, together with any accrued interest to the date of release will be returned to the Borrower. The deposit of the Escrow Funds by the Borrower with the Agent as herein provided will not operate as a repayment of the Aggregate Principal Amount until such time as the Escrow Funds are actually paid to the Lenders, the Issuing Lender or any Non-Extending Lender, as applicable.

ARTICLE 19
CONFIDENTIALITY

19.1          Non-Disclosure. All information, including any information relating to a Hostile Acquisition, other than information that is required by applicable Law or stock exchange requirements to be disclosed by the Party receiving the confidential information to any Administrative Body of competent jurisdiction, will be held by the Parties in the strictest confidence and will not be disclosed to any Person, except as provided in Sections 19.2 and 19.3, provided that the confidential nature of the information is made known or ought to have been known to the disclosing Party.

19.2             Exceptions. Section 19.1 does not apply to confidential information:

(a)     of a Party where that Party consents to its disclosure;

(b)     which becomes part of the public domain;

(c)     received from a third party without restriction on further disclosure and without breach of Section 19.1; or

(d)     developed independently without breach of Section 19.1.

19.3            Permitted Disclosures by Agent and Lenders. Confidential information received by the Agent or a Lender may be disclosed to the Agent or any other Lender or any Affiliate thereof (including a Hedge Lender), including to any financial institution which desires to become a Lender hereunder and agrees prior to such disclosure to become bound by the confidentiality provisions hereof, and to their respective employees, auditors, accountants, legal counsel, geologists, engineers and other consultants and financial advisors retained by the Agent, such Lender, such Affiliate or such financial institution on a need to know basis.

19.4            Survival. The obligations of the Parties under this Article 19 will survive the termination of this Agreement.

ARTICLE 20
ASSIGNMENT

20.1           Assignment of Interests. Except as expressly permitted under this Article 20 and subject to Article 17, this Agreement and the rights and obligations hereunder will not be assignable, in whole or in part, by the Borrower without the prior consent of all of the Lenders.

20.2           Assignment by the Lenders. Each Lender will have the right to sell or assign, in minimum portions of $10,000,000 (unless such assignment is between existing Lenders or consists of a Lender's entire Individual Commitment Amount under a Credit Facility), such Lender's Individual Commitment Amount under a Credit Facility to one or more financial institutions with the consent of the Agent and, in the case of a sale or assignment by a Revolving Lender, the consent of the Issuing Lender and the Swingline

-63-

Lender and, in all cases if no Event of Default has occurred and is continuing, the consent of the Borrower, each such consent not to be unreasonably withheld or delayed, and further provided that at and after the time of the assignment, the Borrower will not be under any obligation to pay, by way of withholding tax or otherwise, any greater amount (other than the Discount Rate for Bankers' Acceptances) than it would have been obliged to pay if the Lender had not made an assignment and provided further that each continuing Lender will at all times maintain an Individual Commitment Amount in an aggregate principal amount at least equal to $10,000,000. Notwithstanding the foregoing, a Lender may sell or assign its Rateable Portion under any Credit Facility or to an Affiliate thereof without the consent of the Agent, the Issuing Lender, the Swingline Lender or the Borrower if (a) such Lender remains liable for its obligations under the Documents notwithstanding such sale or assignment, and (b) the Borrower will not be under any obligation to pay, by way of withholding tax or otherwise, any greater amount than it would have been obliged to pay if the Lender had not made such sale or assignment. An assignment fee of $3,500 for each such assignment (other than to an Affiliate) will be payable to the Agent by the assignor Lender. In the event of such sale or assignment, the Borrower will execute and deliver all such agreements, documents and instruments as the Agent or Lender may reasonably request to effect and recognize such syndication, participation, sale or assignment.

20.3           Effect of Assignment. To the extent that any Lender assigns any portion of its Individual Commitment Amount pursuant to Section 20.2 and such new Lender or new Lenders, as the case may be, has executed and delivered to the Borrower and the Agent an Assignment, such Lender will be relieved and forever discharged of any and all of its covenants and obligations under the Documents in respect of that portion of its Individual Commitment Amount so sold or assigned from and after the effective date of the Assignment and the Borrower's recourse under the Documents in respect of such portion so sold or assigned from and after the effective date of the Assignment will be to such new Lender or new Lenders, as the case may be, only and their successors and permitted assigns.

20.4           Participations. Any Lender may at any time sell to one or more financial institutions or other Persons (each of such financial institutions and other Persons being herein called a "Participant") participating interests in any of the Borrowings, commitments, or other interests of such Lender hereunder, provided, however, that:

(a)     no participation contemplated in this Section 20.4 will relieve such Lender from its commitments or other obligations hereunder or under any other Document;

(b)     such Lender will remain solely responsible for the performance of its commitments and such other obligations as if such participation had not taken place;

(c)     the Agent and the Borrower will continue to deal solely and directly with such Lender in connection with such Lender's rights and obligations under this Agreement and each of the other Documents;

-64-

(d)     no Participant will have any right (through a right of consent or approval or otherwise) to require such Lender to take or refrain from taking any action hereunder or under any other Document; and

(e)     the Borrower will not be required to pay any amount hereunder that is greater than the amount which it would have been required to pay had no participating interest been sold.

ARTICLE 21
ADMINISTRATION OF THE CREDIT FACILITIES

21.1             Authorization and Action.

(a)     Authorization and Action. Each Lender hereby irrevocably appoints and authorizes the Agent to be its agent in its name and on its behalf and to exercise such rights or powers granted to the Agent or the Lenders under the Documents to the extent specifically provided therein and on the terms thereof, together with such powers and authority as are reasonably incidental thereto. As to any matters not expressly provided for by the Documents, the Agent will not be required to exercise any discretion or take any action, but will be required to act or to refrain from acting (and will be fully indemnified and protected by the Lenders to the greatest extent permitted by applicable Law in so acting or refraining from acting) upon the instructions of the Majority Lenders, and such instructions will be binding upon all Lenders, provided however that the Agent will not be required to take any action which, in the opinion of the Agent, might expose the Agent to liability in such capacity, which could result in the Agent incurring any costs and expenses, or which is contrary to the spirit and intent of this Agreement.

(b)     Lenders' Determination. Where the provisions of this Agreement provide that any waiver of or any amendment to any provision of the Documents may be made or any action, consent or other determination in connection with the Documents may be taken or given, with the consent or agreement of the Majority Lenders, then any such waiver, amendment, action, consent or determination so made, so taken or so given with the consent or agreement of the Majority Lenders will be binding on all of the Lenders and all of the Lenders will cooperate in all ways necessary or desirable to implement and effect such waiver, amendment, action, consent or determination.

(c)     Deemed Consent. If the Agent delivers a notice to a Lender requesting advice from such Lender as to whether it consents or objects to any matter in connection with the Documents, then, except as otherwise expressly provided herein, if such Lender does not deliver to the Agent its consent or objection to such matter within the time period referenced in such notice, or if no such period is referenced therein, 10 Banking Days of the delivery of such notice by the Agent to such Lender, such Lender will be deemed not to have consented thereto upon the expiry of such period.

-65-

21.2             Procedure for Making Advances.

(a)     Pro Rata Advances. Subject to Sections 2.3, 2.8(b), 6.3, 6.4, and 6.5, all Advances made by the Lenders under a Credit Facility will be made in accordance with each Lender's Rateable Portion of such Advance under such Credit Facility.

(b)     Instructions from Borrower. Subject to Article 9, the Lenders, through the Agent, will make Advances under the applicable Credit Facility available to the Borrower as required hereunder by debiting the account of the Agent to which each Lender's Rateable Portion of such Advances under such Credit Facility have been credited in accordance with Section 5.6 (or causing such account to be debited) and, in the absence of other arrangements agreed to by the Agent and the Borrower in writing, by transferring (or causing to be transferred) like funds in accordance with the instructions of the Borrower as set forth in the Notice of Drawdown, Notice of Rollover or Notice of Conversion, as the case may be, in respect of each Advance under such Credit Facility, provided that the obligation of the Agent hereunder will be limited to taking such steps as are in keeping with its normal banking practice commercially reasonable in the circumstances to implement such instructions, and the Agent will not be liable for any damages, claims or costs which may be suffered by the Borrower or any of the Lenders and occasioned by the failure of such funds to reach their designated destination, unless such failure is due to the gross negligence or wilful misconduct of the Agent.

(c)     Assumption Respecting Availability. Unless the Agent has been notified by a Lender within 2 Banking Days prior to an anticipated Advance that such Lender will not make available to the Agent its Rateable Portion of such Advance under the applicable Credit Facility, the Agent may assume, without any enquiry required on its part, that such Lender has made or will make such portion of the Advance available to the Agent on the date such Advance is to take place, in accordance with the provisions hereof and the Agent may, in reliance upon such assumption, make available to the Borrower on such date a corresponding amount. If and to the extent such Lender will not have so made its Rateable Portion of an Advance available to the Agent, such Lender agrees to pay to the Agent, forthwith on demand, such Lender's Rateable Portion of the Advance under such Credit Facility and all reasonable costs and expenses incurred by the Agent in connection therewith together with interest thereon (at the rate payable thereunder by the Borrower in respect of such Advance) for each day from the date such amount is made available to the Borrower until the date such amount is paid to the Agent, provided however, that if such Lender fails to so pay, the Borrower covenants and agrees that without prejudice to any rights the Borrower may have against such Lender, it will repay the amount of such Lender's Rateable Portion of the Advance under such Credit Facility (without duplication) to the Agent for the account of the Agent after receipt of the certificate referred to below and forthwith after demand therefor by the Agent. The amount payable to the Agent pursuant hereto will be as set forth in a certificate delivered by the Agent to

-66-

such non-paying Lender and the Borrower (which certificate will contain reasonable details of how the amount payable is calculated) and will be conclusive and binding, for all purposes, in the absence of manifest error. If such Lender makes the payment to the Agent as required herein, the amount so paid will constitute such Lender's Rateable Portion of the Advance under such Credit Facility for purposes of this Agreement. The failure of any Lender to make its Rateable Portion of the Advance under such Credit Facility will not relieve any other Lender under such Credit Facility of its obligation, if any, hereunder to make its Rateable Portion of the Advance on the date that such Advance under such Credit Facility is to take place, but no Lender will be responsible for the failure of any other Lender to provide its Rateable Portion of any Advance under such Credit Facility.

21.3           Remittance of Payments. Forthwith after receipt of any payment by the Borrower hereunder, the Agent, if and to the extent a Lender is entitled thereto, will remit to such Lender its Rateable Portion of such payment, provided that, if the Agent, on the assumption that it will receive on any particular date a payment of principal, interest or fees hereunder, remits to a Lender its Rateable Portion of such payment and the Borrower fails to make such payment, each such Lender agrees to repay to the Agent forthwith on demand such Lender's Rateable Portion of any such payment, together with all reasonable costs and expenses incurred by the Agent in connection therewith and interest thereon at the rate and calculated in the manner customarily applicable to interbank payments for each day from the date such amount is remitted to such Lender. The exact amount of the repayment required to be made by a Lender pursuant hereto will be set forth in a certificate delivered by the Agent to such Lender, which certificate will be conclusive and binding for all purposes in the absence of manifest error.

21.4            Adjustments Among Lenders. Each Lender under a Credit Facility (or Hedge Lender for the purposes of paragraphs (c), (e) and (f) below) agrees that:

(a)     After an acceleration of the Obligations pursuant to Section 18.2, it will at any time or from time to time, upon the request of the Agent as required by any Lender under such Credit Facility, purchase, on a non-recourse basis at par, an undivided participation in the Obligations owing to the other Lenders under such Credit Facility and make any other adjustments which may be necessary or appropriate, in order that the amount of Obligations owing to each Lender under such Credit Facility, as adjusted pursuant to this Section 21.4(a), will be equal to such Lender's Rateable Portion (as determined without regard to any prior adjustments pursuant to Section 2.3, 2.8(b), 6.3, 6.4 or 6.5) of the Obligations owing to all Lenders under such Credit Facility.

(b)     After an acceleration of the Obligations pursuant to Section 18.2, the amount of any repayment made by the Borrower under the Documents and the amount of any proceeds from the exercise of any rights or remedies of the Lenders under the Documents which are to be applied against the Obligations will be so applied in a manner so that to the extent possible the amount of Obligations owing to each Lender under such Credit Facility, after giving effect to such application and

-67-

Section 21.4(a), will be equal to such Lender's Rateable Portion (as determined without regard to any prior adjustments pursuant to Section 2.3, 2.8(b), 6.3, 6.4 or 6.5) of the Obligations owing to all Lenders under such Credit Facility.

(c)     If it exercises any right of counter-claim, set off, bankers' lien or similar right with respect to any property of the Borrower or if under applicable Law it receives a secured claim, the security for which is a debt owed by it to the Borrower, it will apportion the amount thereof proportionately between:

(i)     amounts outstanding at such time owed by the Borrower to such Lender under this Agreement or the Lender Hedge Agreements to which it is a party, which amounts will be applied in accordance with Sections 4.2, 21.4 and Section 22.11; and

(ii)     amounts otherwise owed to it by the Borrower, provided that any cash collateral account held by such Lender as collateral for a letter of credit or bankers' acceptance (including a Bankers' Acceptance or Letter of Credit) issued or accepted by such Lender on behalf of the Borrower may be applied by such Lender to such amounts owed by the Borrower to such Lender pursuant to such letter of credit or in respect of any such bankers' acceptance without apportionment.

(d)     If it receives, through the exercise of a right or the receipt of a secured claim described in paragraph (c) above or otherwise, payment of a proportion of the aggregate amount of principal, interest and fees due to it hereunder which is greater than the proportion received by any other Lender in respect of the aggregate amount of principal, interest and fees due in respect of a Credit Facility (having regard to the respective proportionate amounts advanced as Advances by each of the Lenders under such Credit Facility), the Lender receiving such proportionately greater payment will purchase a participation (which will be deemed to have been done simultaneously with receipt of such payment) in that portion of such Credit Facility of the other Lenders under such Credit Facility so that their respective receipts will be pro rata to their respective Rateable Portions under such Credit Facility, provided however that, if all or part of such proportionately greater payment received by such purchasing Lender will be recovered, such purchase will be rescinded and the purchase price for such participation will be returned to the extent of such recovery, but without interest. Such Lender will exercise its rights in respect of such secured claim in a manner consistent with the rights of the Lenders entitled under this Section 21.4 to share in the benefits of any recovery on such secured claims.

(e)     If it does any act or thing permitted by paragraphs (c) and (d) above, it will promptly provide full particulars thereof to the Agent.

(f)     Except as permitted under paragraphs (c), (d) and (e) above, no Lender will be entitled to exercise any right of counter-claim, set off, bankers' lien or similar right without the prior consent of the other Lenders.

-68-

21.5            Duties and Obligations. The Agent and any of its directors, officers, agents or employees (and, for purposes hereof, the Agent will be deemed to be contracting as agent for and on behalf of such Persons) will not be liable to any Lender for any action taken or omitted to be taken by it under or in connection with the Documents, except for its gross negligence or wilful misconduct. Without limiting the generality of the foregoing, the Agent:

(a)     may assume that there has been no assignment or transfer by the Lenders of their rights under the Documents, unless and until the Agent receives a duly executed Assignment from such Lender;

(b)     may consult with counsel (including counsel for the Borrower), independent public accountants and other experts selected by it and will not be liable for any action taken or omitted to be taken in good faith by it in accordance with or reliance upon the advice of such counsel, accountants or experts;

(c)     will incur no liability under or in respect of the Documents by acting upon any notice, consent, certificate or other instrument or writing believed by it to be genuine and signed or sent by the apparently proper Person or by acting upon any representation or warranty of any Harvest Party made or deemed to be made hereunder;

(d)     may assume that no Default or Event of Default has occurred and is continuing unless it has actual knowledge to the contrary; and

(e)     may rely, as to any matter of fact which might reasonably be expected to be within the knowledge of any Person, upon a certificate signed by or on behalf of such Person.

Further, the Agent (i) does not make any warranty or representation to any Lender nor will it be responsible to any Lender for the accuracy or completeness of the data made available to any of the Lenders in connection with the Credit Facilities, or for any statements, warranties or representations (whether written or oral) made in connection with the Credit Facilities, (ii) will not have any duty to ascertain or to enquire as to the performance or observance of any of the terms, covenants or conditions of the Documents on the part of the Borrower or to inspect the property (including books and records) of the Borrower, and (iii) will not be responsible to any Lender for the due execution, legality, validity, enforceability, genuineness, sufficiency or value of the Documents or any other instrument or document furnished pursuant hereto or thereto.

21.6            Prompt Notice to the Lenders. Notwithstanding any other provision herein, the Agent agrees to provide to the Lenders, with copies where appropriate, all information, notices and reports required to be given to the Agent by the Borrower hereunder, promptly upon receipt of same, excepting therefrom information and notices relating solely to the role of the Agent hereunder.

21.7             Agent and Agent Authority. With respect to its Rateable Portion of the Aggregate Commitment Amount under a Credit Facility and the Advances made by it as a Lender

-69-

under such Credit Facility, as applicable, the Agent will have the same rights and powers under the Documents as any other Lender and may exercise the same as though it were not the Agent. The Agent may accept deposits from, lend money to, and generally engage in any kind of business with the Harvest Parties, their shareholders or unitholders or any Person owned or controlled by any of them and any Person which may do business with any of them, all as if the Agent was not serving as Agent, and without any duty or obligation to account therefor to the Lenders.

21.8            Lenders' Credit Decisions. It is understood and agreed by each Lender that it has itself been, and will continue to be, solely responsible for making its own independent appraisal of and investigations into the financial condition, creditworthiness, condition, affairs, status and nature of the Borrower. Accordingly, each Lender confirms with the Agent that it has not relied, and will not hereafter rely, on the Agent (a) to check or enquire on its behalf into the adequacy, accuracy or completeness of any information provided by the Harvest Parties or any other Person under or in connection with the Credit Facilities (whether or not such information has been or is hereafter distributed to such Lender by the Agent) or (b) to assess or keep under review on its behalf the financial condition, creditworthiness, condition, affairs, status or nature of the Harvest Parties. Each Lender acknowledges that copies of the Documents have been made available to it for review and each Lender acknowledges that it is satisfied with the form and substance of the Documents. A Lender will not make any independent arrangement with the Harvest Parties for the satisfaction of any Indebtedness owing to it under the Documents without the consent of the other Lenders.

21.9            Indemnification. The Lenders hereby agree to indemnify the Agent and its directors, officers, agents and employees (to the extent not reimbursed by the Borrower) in accordance with their aggregate respective Rateable Portions under the Credit Facilities, from and against any and all liabilities, obligations, losses, damages, penalties, actions, judgments, suits, costs, expenses or disbursements of any kind or nature whatsoever which may be imposed on, incurred by, or asserted against the Agent or its directors, officers, agents and employees in any way relating to or arising out of the Documents or any action taken or omitted by the Agent under or in respect of the Documents in its capacity as Agent, provided that no Lender will be liable for any portion of such liabilities, obligations, losses, damages, penalties, actions, judgments, suits, costs, expenses or disbursements resulting from the Agent's gross negligence or wilful misconduct. Without limiting the generality of the foregoing, each Lender agrees to reimburse the Agent promptly upon demand for its aggregate Rateable Portion under the Credit Facilities of any reasonable out-of-pocket expenses (including legal fees, on a solicitor and his own client full indemnity basis) incurred by the Agent in connection with the preservation of any right of the Agent or the Lenders under, or the enforcement of, or legal advice in respect of rights or responsibilities under, the Documents, to the extent that the Agent is not reimbursed for such expenses by the Borrower. This indemnity will survive the termination of the other provisions of this Agreement as a separate and continuing covenant of the Lenders.

21.10           Successor Agent. The Agent may, as hereinafter provided, resign at any time by giving 30 days' prior notice (the "Resignation Notice") thereof to the Lenders and the Borrower.

-70-

The Majority Lenders, with the consent of the Borrower, provided no Event of Default is subsisting, such consent not to be unreasonably withheld, will forthwith upon receipt of the Resignation Notice appoint a successor agent (the "Successor Agent") to assume the duties hereunder of the resigning Agent. Upon the acceptance of any appointment as agent hereunder by a Successor Agent, such Successor Agent will thereupon succeed to and become vested with all the rights, powers, privileges and duties as agent under the Documents of the resigning Agent. Upon such acceptance, the resigning Agent will be discharged from its further duties and obligations as agent under the Documents, but any such resignation will not affect such resigning Agent's obligations hereunder as a Lender, including for its Rateable Portion of the Aggregate Commitment Amount under each Credit Facility. After the resignation of the Agent as agent hereunder, the provisions of this Article 21 will continue to enure to its benefit as to any actions taken or omitted to be taken by it while it was the agent of the Lenders hereunder. Notwithstanding the foregoing, if the Majority Lenders fail to appoint a Successor Agent within 30 days of receipt of the Resignation Notice, the resigning Agent may appoint a Successor Agent from among the Lenders, with the consent of the Borrower, provided no Event of Default is subsisting, such consent not to be unreasonably withheld.

21.11        Takini and Enforcement of Remedies. Except as otherwise provided herein, each Lender hereby acknowledges that, to the extent permitted by applicable Law, rights and remedies provided under the Documents to the Lenders are for the benefit of the Lenders collectively and not severally and further acknowledges that its rights and remedies thereunder are to be exercised not severally but collectively through the Agent upon the decision of the Lenders (with the required majority or unanimity as herein provided), regardless of whether acceleration of Obligations hereunder was made, and accordingly, notwithstanding any of the provisions contained herein, each of the Lenders hereby covenants and agrees that it will not be entitled to take any action with respect to any Credit Facility, including any acceleration of the Obligations or enforcement of the Security, but that any such action will be taken only by the Agent with the prior direction of the Lenders (with the required majority or unanimity as provided herein). Notwithstanding the foregoing, in the absence of written instructions from the Lenders, and where in the sole opinion of the Agent the exigencies of the situation warrant such action, the Agent may without notice to or consent of the Lenders take such action on behalf of the Lenders as it deems appropriate or desirable in the circumstances. Each of the Lenders hereby covenants and agrees that it has not heretofore and will not seek, take, accept or receive any security for any of the Indebtedness of the Harvest Parties under the Documents and will not enter into any agreement with any of the Parties relating in any manner whatsoever to the Credit Facilities, unless all of the Lenders will at the same time obtain the benefit of any such security or agreement, as the case may be.

21.12         Reliance Upon Agent. The Borrower will be entitled to rely upon any certificate, notice or other document or other advice, statement or instruction provided to it by the Agent pursuant to the Documents, and the Borrower will be entitled to deal with the Agent with respect to matters under the Documents which the Agent is authorized hereunder to deal with, without any obligation whatsoever to satisfy itself as to the authority of the Agent to act on behalf of the Lenders and without any liability whatsoever to the Lenders for relying upon any certificate, notice or other document or other advice, statement or

-71-

instruction provided to them by the Agent, notwithstanding any lack of authority of the Agent to provide the same.

21.13         Agent May Perform Covenants. If the Borrower fails to perform any covenant on its part herein contained, the Agent may give notice to the Borrower of such failure and if, within 10 days of such notice (or after the expiry of such other time or cure period as may be required in this Agreement), such covenant remains unperformed, the Agent on behalf of the Lenders may, in its sole discretion but need not, perform any such covenant capable of being performed by it and, if the covenant requires the payment or expenditure of money, the Agent may make such payment or expenditure and all sums so expended will be forthwith payable by the Borrower to the Agent on behalf of the Lenders and will bear interest at the Canadian Prime Rate plus 2%.

21.14         No Liability of Agent. The Agent, in its capacity as agent of the Lenders under the Credit Facilities, will have no responsibility or liability to the Borrower or the Lenders on account of the failure of any Lender to perform its obligations hereunder, or to any Lender on account of the failure of the Borrower to perform its obligations under the Documents.

21.15         Nature of Obligations under this Agreement.

(a)     Obligations Separate. The obligations of each Lender and the Agent under this Agreement are separate. The failure of any Lender to carry out its obligations hereunder will not relieve the other Lenders, the Agent or the Borrower of any of their respective obligations hereunder.

(b)     No Liability for Failure by other Lenders. Neither the Agent nor any Lender will be liable or otherwise responsible for the obligations of any other Lender hereunder.

21.16         Lender Consent.

(a)     Unanimity. Notwithstanding anything herein to the contrary and without limiting in any way the context of any provision in this Agreement requiring the consent, approval or action of all Lenders under any Credit Facility, the following matters will require the approval, consent or agreement, as the context requires, of all Lenders under the Credit Facilities:

(i)     the reduction or forgiveness of any Indebtedness payable by the Borrower to the Lenders under the Credit Facilities or under any of the Documents pertaining to the Credit Facilities;

(ii)    any increase to the Aggregate Commitment Amount under the Credit Facilities or the limit on Swingline Borrowings;

(iii)   the postponement of any maturity date of any Obligations;

-72-

(iv)     subject to Article 17, the requirement for delivery of, or any waiver or material amendment under, or release of, any Security;

(v)     any change in the type of Advances under the Credit Facilities or any change to the covenants referred to in Sections 2.4, 3.2, 3.3, 3.4, 3.6 and 18.3;

(vi)     any amendment to this Section 21.16(a); and

(vii)    any change to the definition of "Majority Lenders".

(b)     Majority Consent. Subject to Section 21.16(a), any waiver of or any amendment to any provision of the Documents as they pertain to the Credit Facilities and any action, consent or other determination in connection with the Documents as they pertain to the Credit Facilities will bind all of the Lenders under the Credit Facilities if such waiver, amendment, action, consent or other determination is agreed to in writing by the Majority Lenders; provided that any waiver or amendment which changes or relates to any material rights or obligations of the Agent, the Swingline Lender or the Issuing Lender shall also require the agreement in writing of such Party.

21.17         Intercreditor Agreement. Each Lender acknowledges that the Agent has or may hereafter enter into each of the Intercreditor Agreement and the Redearth Intercreditor Agreement and is authorized to do so for and on behalf of the Lenders. Notwithstanding anything to the contrary, expressed or implied herein, all rights, powers and recourses available to the Agent and the Lenders under the Documents shall be subject to the Intercreditor Agreement and the Redearth Intercreditor Agreement. The Borrower acknowledges that the Intercreditor Agreement and Redearth Intercreditor Agreement will be entered into by the Agent for the benefit of the Lenders.

22.7           Waiver of Laws. To the extent legally permitted, the Borrower hereby irrevocably and absolutely waives the provisions of any applicable Law which may be inconsistent at any time with, or which may delay or limit in any way, the enforcement of the Documents in accordance with their terms.

-76-

22.8             Attornment and Waiver of Jury Trial. The Parties hereto do hereby irrevocably:

22.9             Interest on Payments in Arrears.

(a)     Except as otherwise provided in this Agreement, interest will be paid by the Parties as follows:

(ii)     on amounts payable by one Party to another Party under the Documents where such payment is in default but the non-payment of such amount has not required an actual out-of-pocket expense by the Party to whom such payment is due, at the Canadian Prime Rate plus 2% from and including the day on which the payment was due to, but excluding the day on which the payment is made whether before or after judgment, but if such payment is a reimbursement by the Lenders to the Borrower for overpayment by it to the Lenders or is in respect of an inadvertent underpayment by the Agent, the Lenders or the Borrower to another Party (based on information provided by such other Party), such interest will only be calculated from the date which is 3 Banking Days following a demand for payment by the Party entitled to it.

(b)     All interest referred to in this Section 22.9 will be simple interest calculated daily on the basis of a 365 or 366 day year, as applicable. For the purposes of the Interest Act (Canada), the annual rates of interest to which such rates are equivalent are the rates so determined multiplied by the actual number of days in a period of one year commencing on the first day of the period for which such interest is payable and divided by 365 or 366, as applicable.

22.10         Payments Due on Banking Day. Whenever any payment hereunder will be due on a day other than a Banking Day, or in the case of LIBOR Based Loans a LIBOR Banking Day, such payment will be made on the next succeeding Banking Day, or LIBOR

22.12         Counterparts. The Documents may be executed in any number of counterparts (including by facsimile transmission) and by different Parties in separate counterparts, each of which when so executed will be deemed to be an original and all of which taken together will constitute one and the same instrument.

22.13         Whole Agreement. This Agreement and the other Documents constitute the entire agreement between the Agent and the Lenders on one hand and the Harvest Parties on the other hand, and cancels and supersedes any other agreements, undertakings, declarations, representations and warranties, written or verbal among all such Parties in respect of the subject matter of this Agreement.
