- 44 -

demand, maturity, default and, to the extent permitted by law, judgment), with interest on overdue interest at the same rate.

4.6Other Interest.

The Borrower shall pay interest on all amounts payable hereunder at the rate specified herein or, if no rate is specified, at the Prime Rate (except where amounts payable are in U.S. Dollars, in which case, at the U.S. Base Rate) calculated daily and compounded monthly, from the date due until paid in full (both before and after demand, maturity, default and, to the extent permitted by law, judgment).

4.7Interest Act (Canada).

For the purpose of the Interest Act (Canada), the yearly rate of interest to which interest calculated on the basis of a year of 360 or 365 days is equivalent is the rate of interest as so determined multiplied by the actual number of days in such year divided by 360 or 365, respectively.

The Borrower acknowledges and confirms that this Section 4.7 satisfies the requirements of Section 4 of the Interest Act (Canada) to the extent it applies to the expression or statement of any interest payable under this Agreement and that the Borrower is able to calculate the yearly rate or percentage of interest payable under this Agreement based upon the methodology set out in this Section 4.7. The Borrower agrees not to plead or assert, whether by way of defence or otherwise, in any proceeding relating to this Agreement, that the interest payable hereunder and the calculation of interest herein have not been adequately disclosed to them, whether pursuant to Section 4 of the Interest Act (Canada) or any other Applicable Law or legal principle.

4.8Deemed Reinvestment Principle.

For the purpose of the Interest Act (Canada), the principle of deemed reinvestment of interest shall not apply to any interest calculation under this Agreement and the rates of interest stipulated in this Agreement are intended to be nominal rates and not effective rates or yields.

4.9Maximum Rate of Interest.

Notwithstanding anything contained herein to the contrary, the Borrower will not be obliged to make any payment of interest or other amounts payable to the Lenders hereunder in excess of the amount or rate that would be permitted by Applicable Law or would result in the receipt by the Lender of interest at a criminal rate (as such terms are construed under the Criminal Code (Canada)). If the making of any payment by the Borrower would result in a payment being made that is in excess of such amount or rate, the particular Lender will determine the payment or payments that are to be reduced or refunded, as the case may be, so that such result does not occur.

6.1Voluntary Repayment of Outstanding Accommodation.

(a)Repayments. Subject to Section7.8, the Borrower shall have the right to voluntarily repay outstanding Accommodations from time to time on any Business Day without premium on the terms and conditions set forth in this Section:

(i)With respect to any voluntary repayment of an Accommodation, unless the Agent, with the consent of the Lenders otherwise approves, the Canadian Dollar Amount of Accommodation included in such repayment shall be Cdn.$2,500,000 or whole multiples of Cdn.$100,000 or the entire amount of that type of Accommodation outstanding, and with respect to U.S. Base Rate Loans, the U.S. Dollar amount of Accommodation included in such repayment shall be U.S.$2,500,000 or whole multiples of U.S.$100,000 or the entire amount of that type of Accommodation outstanding, and the Borrower shall give the Agent a written notice of repayment substantially in the form of Schedule 6.1(A) (a “Notice of Repayment”), specifying the amount, the type or types of Accommodation to be included in the repayment (and the currency and the interest rate applicable thereto) and the applicable voluntary repayment date, which notice shall be irrevocable by the Borrower. The Notice of Repayment shall be given to the Agent not later than 10:00 a.m. on the second Business Day preceding the applicable repayment date in the case of repayments in the aggregate greater than $2,500,000.

(ii)In all other cases, Notice of Repayment shall be given on the applicable repayment date.

LEGAL_1:81779606.19

BMO – BNS - Berkshire –Credit Agreement

- 46 -

(v)Repayment of outstanding Accommodation in the form of a Documentary Credit shall be permitted on the date of surrender thereof by submitting such Documentary Credit to the Documentary Credit Lender for cancellation.

6.2Repayment on Maturity Date and Extension.

(a)Subject to the provisions of this Agreement and to this Section, the Borrower shall repay in full all outstanding Accommodations to each Lender on the Maturity Date of such Lender, together with all interest, fees and other amounts payable hereunder on the Maturity Date of such Lender, in each case, to the Agent for the account of the applicable Lender(s), and the Commitment of such Lender shall be permanently cancelled and the aggregate Committed Amount shall be permanently cancelled by a corresponding amount.

(b)By notice in writing to the Agent in the form of Schedule 3(A) (a “Notice of Extension”) given not more than once per annum and not less than 45 days prior to the Maturity Date, the Borrower may request each Lender to extend the Maturity Date of such Lender for an additional period of 365 days. The Lenders agree that they shall give or withhold their consent in a timely manner so that the Agent may provide a response to the Borrower to the Notice of Extension within thirty (30) days from the date of such receipt, provided that the decision of any Lender to extend the Maturity Date in respect of such Lender shall be at the sole discretion of such Lender. If 100% of the Lenders agree to such extension, the then current Maturity Date shall be extended for an additional 365 days computed from the then current Maturity Date. If Lenders holding more than 66 2/3% of the Commitments decline the requested extension, the Maturity Date shall be the then current Maturity Date. If Lenders holding at least 66 2/3% of the Commitments but less than 100% of the Commitments agree to such extension, the Borrower may, in its sole discretion, either (a) advise the Agent in writing of its determination to not extend the Maturity Date in which case the Credit Facilities will continue in accordance with its terms, or (b) elect to extend the then current Maturity Date for an additional 365 days computed from the expiry of the then current Maturity Date, such extension applying only to those Lenders which provided their consent to the extension. In the case of any Lender not consenting to an extension (a “Dissenting Lender”), such Lender’s obligations pursuant to this Agreement shall continue in accordance with the terms hereof to the then current Maturity Date. In the event that the Borrower elects to extend the then current Maturity Date in accordance with the preceding terms then with respect to an Dissenting Lender, at any time on or prior to the then current Maturity Date, the Borrower shall either (x) permanently cancel the Commitment of any Dissenting Lender and repay such Dissenting Lender, at which time the Committed Amount shall be permanently reduced by the amount of such Commitment, or (y) replace the Dissenting Lender with another existing Lender or Lenders without the consent of any of the remaining Lenders, or with any financial institution which is not an existing Lender with the consent of the Agent and the Documentary Credit Lender, such consent not to be unreasonably withheld.

6.3Excess Accommodation.

In addition to the other repayment rights, obligations or options set forth in this Article, if the aggregate Canadian Dollar Amount of all Accommodations outstanding under the Credit Facility at any time exceeds the Committed Amount, the Borrower shall immediately upon request of the Agent, repay such excess.

6.4Illegality.

Notwithstanding any other provision of this Agreement, if the making or continuation of any Accommodation shall have been made unlawful or prohibited due to compliance by any of the Agent and the Lenders in good faith with any change made after the date hereof in any law or governmental rule, regulation, guideline or order, or in any interpretation or application of any law or governmental rule, regulation, guideline or order by any competent authority, or with any request or directive (whether or not having the force of law) by any central bank, reserve board, superintendent of financial institutions or other comparable authority made after the date hereof, then the Agent will give notice thereof to the Borrower which shall repay such Accommodation within a reasonable period or such shorter period as may be required by law.

This indemnity shall constitute an obligation separate and independent from any other obligation contained in this Agreement, shall give rise to a separate and independent cause of action, shall apply irrespective of any indulgence granted by the Lenders from time to time, shall continue in full force and effect notwithstanding any judgment or order for a liquidated sum in respect of an amount due under this Agreement or under any judgment or order and shall not merge in any order of foreclosure made in respect of any of the security given by the Borrower to or for the benefit of any Lender.

7.6General Indemnity.

The Borrower shall indemnify the Agent and the Lenders and their directors, officers, employees and agents against and hold each of them harmless from any loss, liabilities, damages, claims, costs and expenses (including fees and expenses of counsel to the Agent and the Lenders on a solicitor and his own client basis and reasonable fees and expenses of all independent consultants) (each a “Claim”) suffered or incurred by any of them arising out of, resulting from or in any manner connected with or related to:

(a)any Environmental Matter, Environmental Liability or Environmental Proceeding; and

(b)any loss or expense incurred in liquidating or re-employing deposits from which such funds were obtained, which the Agent or Lender may sustain or incur as a consequence of:

(iii)any breach, non-observance or non-performance by the Borrower of any of its obligations, covenants, agreements, representations or warranties contained in this Agreement; and

(iv)the repayment of any CORRA Loan other than on the Interest Payment Date thereof.

The indemnity set forth herein shall be in addition to any other obligations or liabilities of the Borrower to any of the Agent and the Lenders at common law or otherwise and this Section shall survive the repayment of the Accommodation and the termination of this Agreement. A certificate of the Lender as to any such loss or expense, providing details of the calculation of such loss or expense, shall be prima facie evidence.

7.7Reserved.

In the event of (a) the payment of any principal of any Term CORRA Loan or Daily Compounded CORRA Loan, as applicable, prior to the applicable Interest Payment Date

A certificate of any Lender setting forth any amount or amounts that such Lender is entitled to receive pursuant to this Section delivered to the Borrower shall be presumptively correct absent manifest error.

In such event either the Lenders or the Administrative Agent on their behalf may, in their discretion, exercise any right or recourse and/or proceed by any action, suit, remedy or proceeding against any obligor authorized or permitted by law for the recovery of all the obligations of the Borrower to the Lenders and proceed to exercise any and all rights hereunder (including the remedies set out in (a) through (c) above) and under any securityand no such remedy for the enforcement of the rights of the Lenders shall be exclusive of or dependent on any other remedy but any one or more of such remedies may from time to time be exercised independently or in combination.

12.3Remedies Cumulative.

The rights and remedies of the Lenders and the Agent under this Agreement and the Loan Documents are cumulative and are in addition to and not in substitution for any other rights or remedies. Nothing contained herein or in the Loan Documents with respect to the indebtedness or liability of the Borrower to the Agent and the Lenders or any part thereof, nor any act or omission of the Agent and the Lenders with respect to the Loan Documents shall in any way prejudice or affect the rights, remedies and powers of the Agent and the Lenders hereunder or under the Loan Documents.

12.4Appropriation of Moneys Received.

The Lenders, and the Agent on behalf of the Lenders as between the Lenders and the Borrower, may from time to time when an Event of Default has occurred and is continuing appropriate any monies received from the Borrower in or toward payment of such of the obligations of the Borrower hereunder as the Lenders in their sole discretion may see fit.

12.5Non-Merger.

The taking of any action or dealing whatsoever by the Lender or the Agent in respect of the Borrower or any security shall not operate as a merger of any of the obligations of the Borrower to the Lenders or the Agent or in any way suspend payment or affect or prejudice the rights, remedies and powers, legal or equitable, which the Lenders or the Agent may have under Section 12.3 in connection with such obligations.

12.6Waiver.

No delay on the part of the Lenders or the Agent in exercising any right or privilege hereunder shall operate as a waiver thereof. No Default or Event of Default shall be waived except by a written waiver in accordance with Section 21.1. Each written waiver shall apply only to the Default or Event of Default to which it is expressed to apply. No written waiver shall preclude the subsequent exercise by the Lenders or the Agent of any right, power or privilege hereunder or extend to or apply to any other Default or Event of Default.

12.7Set-off.

Upon the occurrence and during the continuance of any Event of Default, each Lender is authorized at any time and from time to time, to the fullest extent permitted by law (including general principles of common law), to set off and apply any and all deposits (general or special, time or demand, provisional or final) at any time held and other indebtedness at any time owing by it to or for the credit or the account of the Borrower against any and all of the obligations of the Borrower under any of the Loan Documents, irrespective of whether or not the Lender has made demand under any of the Loan Documents and although such obligations may be unmatured or contingent. If an obligation is unascertained, the Lender may, in good faith, estimate the obligation and exercise its right of set-off in respect of the estimate, subject to

LEGAL_1:81779606.19

BMO – BNS - Berkshire –Credit Agreement

- 66 -

providing the Borrower with an accounting when the obligation is finally determined. Each Lender shall promptly notify the Borrower after any set-off and application is made by it, provided that the failure to give notice shall not affect the validity of the set-off and application. The rights of the Lenders under this Section 12.7 are in addition to other rights and remedies (including all other rights of set-off) which the Lenders may have.

ARTICLE 13
YIELD PROTECTION

13.1Increased Costs.

(a)Increased Costs Generally. If any Change in Law shall:

(i)impose, modify or deem applicable any reserve, special deposit, compulsory loan, insurance charge or similar requirement against assets of, deposits with or for the account of, or credit extended or participated in by, any Lender;

(ii)subject any Lender to any Tax of any kind whatsoever with respect to this Agreement or any Accommodations made by it, or change the basis of taxation of payments to such Lender in respect thereof, except for Indemnified Taxes or Other Taxes covered by Section 13.2 and the imposition, or any change in the rate, of any Excluded Taxes payable by such Lender; or

(iii)impose on any Lender or any applicable interbank market any other condition, cost or expense affecting this Agreement, Term CORRA Loans or Daily Compounded CORRA Loans, or Accommodations made by such Lender;

and the result of any of the foregoing shall be to increase the cost to such Lender of making or maintaining any Accommodation (or of maintaining its obligation to make any such Accommodation), or to increase the cost to such Lender, or to reduce the amount of any sum received or receivable by such Lender hereunder (whether of principal, interest or any other amount), then upon request of such Lender the Borrower will pay to such Lender such additional amount or amounts as will compensate such Lender for such additional costs incurred or reduction suffered.

(b)Capital Requirements. If any Lender determines that any Change in Law affecting such Lender, or any lending office of such Lender or such Lender’s holding company, if any, regarding capital requirements has or would have the effect of reducing the rate of return on such Lender’s capital or on the capital of such Lender’s holding company, if any, as a consequence of this Agreement, the Commitments of such Lender or the Accommodations made by such Lender, to a level below that which such Lender or its holding company could have achieved but for such Change in Law (taking into consideration such Lender’s policies and the policies of its holding company with respect to capital adequacy), then from time to time the Borrower will pay to such Lender such additional amount or amounts as will compensate such Lender or its holding company for any such reduction suffered.

(c)Certificates for Reimbursement. A certificate of a Lender setting forth the amount or amounts necessary to compensate such Lender or its holding company, as the case may be, as specified in paragraph (a) or (b) of this Section (“Additional Compensation”), including a description of the event by reason of

LEGAL_1:81779606.19

BMO – BNS - Berkshire –Credit Agreement

- 67 -

which it believes it is entitled to such compensation, and supplying reasonable supporting evidence (including, in the event of a Change in Law, a photocopy of the Applicable Law evidencing such change) and reasonable detail of the basis of calculation of the amount or amounts, and delivered to the Borrower shall be conclusive absent manifest error. The Borrower shall pay such Lender the amount shown as due on any such certificate within 10 days after receipt thereof. In the event the Lender subsequently recovers all or part of the Additional Compensation paid by the Borrower, it shall promptly repay an equal amount to the Borrower. The obligation to pay such Additional Compensation for subsequent periods will continue until the earlier of termination of the Accommodation or the Commitment affected by the Change in Law, change in capital requirement or the lapse or cessation of the Change in Law giving rise to the initial Additional Compensation. A Lender shall make reasonable efforts to limit the incidence of any such Additional Compensation and seek recovery for the account of the Borrower upon such Borrower’s request at such Borrower’s expense, provided such Lender in its reasonable determination suffers no appreciable economic, legal, regulatory or other disadvantage. Notwithstanding the foregoing provisions, a Lender shall only be entitled to rely upon the provisions of this Section 13.1 if and for so long as it is not treating the Borrower in any materially different or in any less favourable manner than is applicable to any other customers of such Lender, where such other customers are bound by similar provisions to the foregoing provisions of this Section 13.1.

(d)Delay in Requests. Failure or delay on the part of any Lender to demand compensation pursuant to this Section shall not constitute a waiver of such Lender’s right to demand such compensation, except that the Borrower shall not be required to compensate a Lender pursuant to this Section for any increased costs incurred or reductions suffered more than nine months prior to the date that such Lender notifies the Borrower of the Change in Law giving rise to such increased costs or reductions and of such Lender’s intention to claim compensation therefore, unless the Change in Law giving rise to such increased costs or reductions is retroactive, in which case the nine-month period referred to above shall be extended to include the period of retroactive effect thereof.

13.2Taxes.

(a)Payments Subject to Taxes. If the Borrower, the Agent or any Lender is required by Applicable Law to deduct or withhold any Taxes in respect of any payment by or on account of any obligation of the Borrower hereunder or under any other Loan Document, then (i) in the case of Indemnified Taxes the sum payable shall be increased by the Borrower when payable as necessary so that after making or allowing for all required deductions and withholdings (including deductions and withholdings on account of Indemnified Taxes applicable to additional sums payable under this Section) the Agent or Lender, as the case may be, receives an amount equal to the sum it would have received had no such deductions or withholdings been required, (ii) the Borrower shall make any such deductions or withholdings required to be made by it under Applicable Law and (iii) the Borrower shall timely pay the full amount required to be deducted or withheld to the relevant Governmental Authority in accordance with Applicable Law.

(b)Payment of Other Taxes by the Borrower. Without limiting the provisions of paragraph (a) above, the Borrower shall timely pay any Other Taxes to the relevant Governmental Authority in accordance with Applicable Law.

LEGAL_1:81779606.19

BMO – BNS - Berkshire –Credit Agreement

- 68 -

(c)Indemnification by the Borrower. The Borrower shall indemnify the Agent and each Lender, within 15 days after written demand therefor, for the full amount of any Indemnified Taxes (including Indemnified Taxes imposed or asserted on or attributable to amounts payable under this Section) paid by the Agent or such Lender and reasonable expenses arising therefrom or with respect thereto, whether or not such Indemnified Taxes were correctly or legally imposed or asserted by the relevant Governmental Authority. A certificate as to the amount of such payment or liability delivered to the Borrower by a Lender (with a copy to the Agent), or by the Agent on its own behalf or on behalf of a Lender, shall be conclusive absent manifest error. In the event the Lender subsequently recovers all or part of the payment made under this Section paid by the Borrower, it shall promptly repay an equal amount to the Borrower.

(d)Evidence of Payments. As soon as practicable after any payment of Indemnified Taxes by the Borrower to a Governmental Authority, the Borrower shall deliver to the Agent the original or a certified copy of a receipt issued by such Governmental Authority evidencing such payment, a copy of the return reporting such payment or other evidence of such payment reasonably satisfactory to the Agent.

(e)Status of Lenders. Any Foreign Lender that is entitled to an exemption from or reduction of withholding tax under the law of the jurisdiction in which the Borrower is resident for tax purposes, or any treaty to which such jurisdiction is a party, with respect to payments hereunder or under any other Loan Document shall, at the request of the Borrower, deliver to the Borrower (with a copy to the Agent), at the time or times prescribed by Applicable Law or reasonably requested by the Borrower or the Agent, such properly completed and executed documentation prescribed by Applicable Law as will permit such payments to be made without withholding or at a reduced rate of withholding. In addition any Lender, if requested by the Borrower or the Agent, shall deliver such other documentation prescribed by Applicable Law or reasonably requested by the Borrower or the Agent as will enable the Borrower or the Agent to determine whether or not such Lender is subject to withholding or information reporting requirements.

(f)Treatment of Certain Refunds and Tax Reductions. If the Agent or a Lender determines, in its sole discretion, that it has received a refund of any Taxes or as to which it has been indemnified by the Borrower or with respect to which the Borrower has paid additional amounts pursuant to this Section 13.2, it shall pay to the Borrower an amount equal to such refund (but only to the extent of indemnity payments made, or additional amounts paid, by the Borrower under this Section with respect to the Taxes giving rise to such refund or reduction), net of all out-of-pocket expenses of the Agent or such Lender, as the case may be, and without interest (other than any net after-Tax interest paid by the relevant Governmental Authority with respect to such refund). The Borrower upon the request of the Agent or such Lender, agrees to repay the amount paid over to the Borrower (plus any penalties, interest or other charges imposed by the relevant Governmental Authority) to the Agent or such Lender if the Agent or such Lender is required to repay such refund or reduction to such Governmental Authority. This paragraph shall not be construed to require the Agent or any Lender to make available its tax returns (or any other information relating to its taxes that it deems confidential) to the Borrower or any other Person, to arrange its affairs in any particular manner or to claim any available refund or reduction.

LEGAL_1:81779606.19

BMO – BNS - Berkshire –Credit Agreement

- 69 -

(g)FATCA. If a payment made to a Lender under any Loan Document would be subject to withholding taxes imposed by FATCA, if such Lender were to fail to comply with the applicable reporting requirements of FATCA (including those contained in Section 1471(b) or 1472(b) of the Internal Revenue Code, as applicable), such Lender shall deliver to the Borrower and the Agent at the time or times prescribed by law and at such time or times reasonably requested by the Borrower or the Agent such documentation prescribed by applicable law (including as prescribed by Section 1471(b)(3)(C)(i) of the Internal Revenue Code) and such additional documentation reasonably requested by the Borrower or the Agent as may be necessary for the Borrower and the Agent to comply with their obligations under FATCA and to determine that such Lender has complied with such Lender’s obligations under FATCA or to determine the amount to deduct and withhold from such payment. Solely for purposes of this clause (g), “FATCA” shall include any amendments made to FATCA after the date of this Agreement.

The provisions of this Section 13.2 shall survive the resignation or replacement of the Administrative Agent or any assignment of rights by, or the replacement of, a Lender, the termination of the Commitments and the repayment, satisfaction or discharge of all obligations under any Credit Document, repayment of the Loans, and termination of this Agreement.

13.3Mitigation Obligations: Replacement of Lenders.

(a)Designation of a Different Lending Office. If any Lender requests compensation under Section 13.1, or requires the Borrower to pay any additional amount to any Lender or any Governmental Authority for the account of any Lender pursuant to Section 13.2, then such Lender shall use reasonable efforts to designate a different lending office for funding or booking its Accommodations hereunder or to assign its rights and obligations hereunder to another of its offices, branches or Affiliates, if, in the judgment of such Lender (with the prior consent of the Borrower), such designation or assignment (i) would eliminate or reduce amounts payable pursuant to Section 13.1 or Section 13.2, as the case may be, in the future and (ii) would not subject such Lender to any unreimbursed cost or expense and would not otherwise be disadvantageous to such Lender. The Borrower hereby agrees to pay all reasonable out-of-pocket costs and expenses incurred by any Lender in connection with any such designation or assignment.

(b)Replacement of Lenders. If any Lender requests compensation under Section 13.1, the Borrower is required to pay any additional amount to any Lender or any Governmental Authority for the account of any Lender pursuant to Section 13.2, any Lender’s obligations are suspended pursuant to Section 13.4, or any Lender defaults in its obligation to fund Accommodations hereunder, then the Borrower may either, at its sole expense and effort, upon ten (10) days’ notice to such Lender and the Agent: (i) repay all outstanding amounts due to such affected Lender (or such portion which has not been acquired pursuant to clause (ii) below) and thereupon such Commitment of the affected Lender shall be permanently cancelled and the aggregate Commitment shall be permanently reduced by the same amount and the Commitment of each of the other Lenders shall remain the same; or (ii) require such Lender to assign, without recourse (in accordance with and subject to the restrictions contained in, and consents required by, Article 20), all of its interests, rights and obligations under this Agreement and the related Loan Documents to an assignee that shall assume such obligations (which assignee may be another Lender, if a Lender accepts such assignment), provided that:

LEGAL_1:81779606.19

BMO – BNS - Berkshire –Credit Agreement

- 70 -

(i)the Borrower pays the Agent the assignment fee specified in Section 20.1(b)(vi);

(ii)the assigning Lender receives payment of an amount equal to the outstanding principal of its Accommodations outstanding and participations in disbursements under Documentary Credits, accrued interest thereon, accrued fees and all other amounts payable to it hereunder and under the other Loan Documents (including any breakage costs and amounts required to be paid under this Agreement as a result of prepayment to a Lender) from the assignee (to the extent of such outstanding principal and accrued interest and fees) or the Borrower (in the case of all other amounts);

(iii)in the case of any such assignment resulting from a claim for compensation under Section 13.1 or payments required to be made pursuant to Section 13.2, such assignment will result in a reduction in such compensation or payments thereafter; and

(iv)such assignment does not conflict with Applicable Law.

A Lender shall not be required to make any such assignment or delegation if, prior thereto, as a result of a waiver by such Lender or otherwise, the circumstances entitling the Borrower to require such assignment and delegation cease to apply.

13.4Illegality.

If any Lender determines that any Applicable Law has made it unlawful, or that any Governmental Authority has asserted that it is unlawful, for any Lender or its applicable lending office to make or maintain any Accommodations, or to determine or charge interest rates based upon any particular rate, then, on notice thereof by such Lender to the Borrower through the Agent, any obligation of such Lender with respect to the activity that is unlawful shall be suspended until such Lender notifies the Agent and the Borrower that the circumstances giving rise to such determination no longer exist. Upon receipt of such notice, the Borrower shall, upon demand from such Lender (with a copy to the Agent), prepay or, if conversion would avoid the activity that is unlawful, convert any Accommodations, or take any necessary steps with respect to any Documentary Credits in order to avoid the activity that is unlawful. Upon any such prepayment or conversion, the Borrower shall also pay accrued interest on the amount so prepaid or converted. Each Lender agrees to designate a different lending office if such designation will avoid the need for such notice and will not, in the good faith judgment of such Lender, otherwise be materially disadvantageous to such Lender.

ARTICLE 14
RIGHT OF SETOFF

14.1Right of Setoff.

If an Event of Default has occurred and is continuing, each of the Lenders and each of their respective Affiliates is hereby authorized at any time and from time to time to set off and apply any and all deposits (general or special, time or demand, provisional or final, in whatever currency) at any time held and other obligations (in whatever currency) at any time owing by such Lender or any such Affiliate to or for the credit or the account of the Borrower against any and all of the obligations of the Borrower or any guarantor now or hereafter existing under this Agreement or any other Loan Document to such Lender, irrespective of whether or not such Lender has made any demand under this Agreement or any other Loan Document and although such obligations of the Borrower may be contingent or unmatured or are owed to a branch or

LEGAL_1:81779606.19

BMO – BNS - Berkshire –Credit Agreement

- 71 -

office of such Lender different from the branch or office holding such deposit or obligated on such indebtedness. The rights of each the Lenders and their respective Affiliates under this Section are in addition to other rights and remedies (including other rights of setoff, consolidation of accounts and bankers’ lien) that the Lenders or their respective Affiliates may have. Each Lender agrees to promptly notify the Borrower and the Agent after any such setoff and application, but the failure to give such notice shall not affect the validity of such setoff and application. If any Affiliate of a Lender exercises any rights under this Section 14.1, it shall share the benefit received in accordance with Section 15.1 as if the benefit had been received by the Lender of which it is an Affiliate.

ARTICLE 15
SHARING OF PAYMENTS BY LENDERS

15.1Sharing of Payments by Lenders.

If any Lender, by exercising any right of setoff or counterclaim or otherwise, obtains any payment or other reduction that might result in such Lender receiving payment or other reduction of a proportion of the aggregate amount of its Accommodations and accrued interest thereon or other obligations hereunder greater than its pro rata share thereof as provided herein, then the Lender receiving such payment or other reduction shall (a) notify the Agent of such fact, and (b) purchase (for cash at face value) participations in the Accommodations outstanding and such other obligations of the other Lenders, or make such other adjustments as shall be equitable, so that the benefit of all such payments shall be shared by the Lenders rateably in accordance with the aggregate amount of principal of and accrued interest on their respective Accommodations outstanding and other amounts owing them, provided that:

(a)if any such participations are purchased and all or any portion of the payment giving rise thereto is recovered, such participations shall be rescinded and the purchase price restored to the extent of such recovery, without interest;

(b)the provisions of this Section shall not be construed to apply to (x) any payment made by the Borrower pursuant to and in accordance with the express terms of this Agreement or (y) any payment obtained by a Lender as consideration for the assignment of or sale of a participation in any of its Accommodations or participations in disbursements under Documentary Credits to any assignee or Participant, other than to the Borrower or any Affiliate of the Borrower (as to which the provisions of this Section shall apply); and

(c)the provisions of this Section shall not be construed to apply to (w) any payment made while no Event of Default has occurred and is continuing in respect of obligations of the Borrower to such Lender that do not arise under or in connection with the Loan Documents, (x) any payment made in respect of an obligation that is secured by a Permitted Lien or that is otherwise entitled to priority over the Borrower’s obligations under or in connection with the Loan Documents, (y) any reduction arising from an amount owing to the Borrower upon the termination of derivatives entered into between the Borrower and such Lender, or (z) any payment to which such Lender is entitled as a result of any form of credit protection obtained by such Lender.

The Borrower's consent to the foregoing and agree, to the extent they may effectively do so under Applicable Law, that any Lender acquiring a participation pursuant to the foregoing arrangements may exercise against the Borrower rights of setoff and counterclaim and similar rights of Lenders with respect to such participation as fully as if such Lender were a direct creditor of the Borrower in the amount of such participation.

ARTICLE 16
AGENT’S CLAWBACK

16.1Agent’s Clawback.

(a)Funding by Lenders; Presumption by Agent. Unless the Agent shall have received notice from a Lender prior to the proposed date of any advance of funds that such Lender will not make available to the Agent such Lender’s share of such advance, the Agent may assume that such Lender has made such share available on such date in accordance with the provisions of this Agreement concerning funding by Lenders and may, in reliance upon such assumption, make available to the Borrower a corresponding amount. In such event, if a Lender has not in fact made its share of the applicable advance available to the Agent, then the applicable Lender shall pay to the Agent forthwith on demand such corresponding amount with interest thereon, for each day from and including the date such amount is made available to the Borrower to but excluding the date of payment to the Agent, at a rate determined by the Agent in accordance with prevailing banking industry practice on interbank compensation. If such Lender pays such amount to the Agent, then such amount shall constitute such Lender’s Accommodation included in such advance. If the Lender does not do so forthwith, the Borrower shall pay to the Agent forthwith on written demand such corresponding amount with interest thereon at the interest rate applicable to the advance in question. Any payment by the Borrower shall be without prejudice to any claim the Borrower may have against a Lender that has failed to make such payment to the Agent.

(b)Payments by Borrower; Presumptions by Agent. Unless the Agent shall have received notice from the Borrower prior to the date on which any payment is due to the Agent for the account of any Lender hereunder that the Borrower will not make such payment, the Agent may assume that the Borrower has made such payment on such date in accordance herewith and may, in reliance upon such assumption, distribute the amount due to the Lenders. In such event, if the Borrower has not in fact made such payment, then each of the Lenders severally agrees to repay to the Agent forthwith on demand the amount so distributed to such Lender with interest thereon, for each day from and including the date such amount is distributed to it to but excluding the date of payment to the Agent, at a rate determined by the Agent in accordance with prevailing banking industry practice on interbank compensation.

ARTICLE 17
AGENCY

17.1Appointment and Authority.

Each of the Lenders hereby irrevocably appoints the Agent to act on its behalf as the Agent hereunder and under the other Loan Documents and authorizes the Agent to take such actions on its behalf and to exercise such powers as are delegated to the Agent by the terms hereof or thereof, together with such actions and powers as are reasonably incidental thereto. The provisions of this Article are solely for the benefit of the Agent and the Lenders, and the Borrower shall not have rights as a third party beneficiary of any of such provisions.

17.2Rights as a Lender.

The Person serving as the Agent hereunder shall have the same rights and powers in its capacity as a Lender as any other Lender and may exercise the same as though it were not the Agent and

LEGAL_1:81779606.19

BMO – BNS - Berkshire –Credit Agreement

- 73 -

the term “Lender” or “Lenders” shall, unless otherwise expressly indicated or unless the context otherwise requires, include the Person serving as the Agent hereunder in its individual capacity. Such Person and its Affiliates may accept deposits from, lend money to, act as the financial advisor or in any other advisory capacity for and generally engage in any kind of business with the Borrower or any Affiliate thereof as if such Person were not the Agent and without any duty to account to the Lenders.

17.3Exculpatory Provisions.

(a)The Agent shall not have any duties or obligations except those expressly set forth herein and in the other Loan Documents. Without limiting the generality of the foregoing, the Agent:

(i)shall not be subject to any fiduciary or other implied duties, regardless of whether a Default has occurred and is continuing;

(ii)shall not have any duty to take any discretionary action or exercise any discretionary powers, except discretionary rights and powers expressly contemplated hereby or by the other Loan Documents that the Agent is required to exercise as directed in writing by the Majority Lenders (or such other number or percentage of the Lenders as shall be expressly provided for in the Loan Documents), but the Agent shall not be required to take any action that, in its opinion or the opinion of its counsel, may expose the Agent to liability or that is contrary to any Loan Document or Applicable Law; and

(iii)shall not, except as expressly set forth herein and in the other Loan Documents, have any duty to disclose, and shall not be liable for the failure to disclose, any information relating to the Borrower or any of their Affiliates that is communicated to or obtained by the Person serving as the Agent or any of its Affiliates in any capacity.

(b)The Agent shall not be liable for any action taken or not taken by it (i) with the consent or at the request of the Majority Lenders (or such other number or percentage of the Lenders as is necessary, or as the Agent believes in good faith is necessary, under the provisions of the Loan Documents) or (ii) in the absence of its own gross negligence or wilful misconduct. The Agent shall be deemed not to have knowledge of any Default unless and until notice describing the Default is given to the Agent by the Borrower or a Lender.

(c)Except as otherwise expressly specified in this Agreement, the Agent shall not be responsible for or have any duty to ascertain or inquire into (i) any statement, warranty or representation made in or in connection with this Agreement or any other Loan Document, (ii) the contents of any certificate, report or other document delivered hereunder or thereunder or in connection herewith or therewith, (iii) the performance or observance of any of the covenants, agreements or other terms or conditions set forth herein or therein or the occurrence of any Default, (iv) the validity, enforceability, effectiveness or genuineness of this Agreement, any other Loan Document or any other agreement, instrument or document or (v) the satisfaction of any condition specified in this Agreement, other than to confirm receipt of items expressly required to be delivered to the Agent.

17.4Reliance by Agent.

The Agent shall be entitled to rely upon, and shall not incur any liability for relying upon, any notice, request, certificate, consent, statement, instrument, document or other writing (including any electronic message, Internet or intranet posting or other distribution) believed by it to be genuine and to have been signed, sent or otherwise authenticated by the proper Person. The Agent also may rely upon any statement made to it orally or by telephone and believed by it to have been made by the proper Person, and shall not incur any liability for relying thereon. In determining compliance with any condition hereunder to the making of an Accommodation that by its terms must be fulfilled to the satisfaction of a Lender, the Agent may presume that such condition is satisfactory to such Lender unless the Agent shall have received notice to the contrary from such Lender prior to the making of such Accommodation or the issuance of such Documentary Credit. The Agent may consult with legal counsel (who may be counsel for the Borrower), independent accountants and other experts selected by it, and shall not be liable for any action taken or not taken by it in accordance with the advice of any such counsel, accountants or experts.

17.5Indemnification of Agent.

Each Lender agrees to indemnify the Agent and hold it harmless (to the extent not reimbursed by the Borrower), rateably according to its Applicable Percentage (and not jointly or jointly and severally) from and against any and all losses, claims, damages, liabilities and related expenses, including the fees, charges and disbursements of any counsel, which may be incurred by or asserted against the Agent in any way relating to or arising out of the Loan Documents or the transactions therein contemplated. However, no Lender shall be liable for any portion of such losses, claims, damages, liabilities and related expenses resulting from the Agent’s gross negligence or wilful misconduct.

17.6Delegation of Duties.

The Agent may perform any and all of its duties and exercise its rights and powers hereunder or under any other Loan Document by or through any one or more sub-agents appointed by the Agent from among the Lenders (including the Person serving as Agent) and their respective Affiliates. The Agent and any such sub-agent may perform any and all of its duties and exercise its rights and powers by or through their respective Related Parties. The provisions of this Article and other provisions of this Agreement for the benefit of the Agent shall apply to any such sub-agent and to the Related Parties of the Agent and any such sub-agent, and shall apply to their respective activities in connection with the syndication of the Credit Facilities provided for herein as well as activities as Agent.

17.7Replacement of Agent.

(a)The Agent may at any time give notice of its resignation to the Lenders and the Borrower. Upon receipt of any such notice of resignation, the Majority Lenders shall have the right, with the prior consent of the Borrower, to appoint a successor, which shall be a Lender having an office in Toronto, Ontario or Calgary Alberta or an Affiliate of any such Lender with an office in Toronto or Calgary. The Agent may also be removed at any time by the Majority Lenders upon 30 days’ notice to the Agent and the Borrower as long as the Majority Lenders, with the prior consent of the Borrower, appoint and obtain the acceptance of a successor within such 30 days, which shall have an office in Toronto/Calgary, or an Affiliate of any such Lender with an office in Toronto/Calgary.

LEGAL_1:81779606.19

BMO – BNS - Berkshire –Credit Agreement

- 75 -

(b)If no such successor shall have been so appointed by the Majority Lenders and shall have accepted such appointment within 30 days after the retiring Agent gives notice of its resignation, then the retiring Agent may on behalf of the Lenders, appoint a successor Agent meeting the qualifications specified in Section 17.7(a), provided that if the Agent shall notify the Borrower and the Lenders that no qualifying Person has accepted such appointment, then such resignation shall nonetheless become effective in accordance with such notice and (a) the retiring Agent shall be discharged from its duties and obligations hereunder and under the other Loan Documents (except that in the case of any collateral security held by the Agent on behalf of the Lenders under any of the Loan Documents, the retiring Agent shall continue to hold such collateral security until such time as a successor Agent is appointed); and (b) all payments, communications and determinations provided to be made by, to or through the Agent shall instead be made by or to each Lender directly, until such time as the Majority Lenders appoint a successor Agent as provided for above in the preceding paragraph.

(c)Upon a successor’s appointment as Agent hereunder, such successor shall succeed to and become vested with all of the rights, powers, privileges and duties of the former Agent, and the former Agent shall be discharged from all of its duties and obligations hereunder or under the other Loan Documents (if not already discharged therefrom as provided in the preceding paragraph). The fees payable by the Borrower to a successor Agent shall be the same as those payable to its predecessor unless otherwise agreed between the Borrower and such successor. After the termination of the service of the former Agent, the provisions of this Article 17 and of Article 19 shall continue in effect for the benefit of such former Agent, its sub-agents and their respective Related Parties in respect of any actions taken or omitted to be taken by any of them while the former Agent was acting as Agent.

17.8Non-Reliance on Agent and Other Lenders.

Each Lender acknowledges that it has, independently and without reliance upon the Agent or any other Lender or any of their Related Parties and based on such documents and information as it has deemed appropriate, made its own credit analysis and decision to enter into this Agreement. Each Lender also acknowledges that it will, independently and without reliance upon the Agent or any other Lender or any of their Related Parties and based on such documents and information as it shall from time to time deem appropriate, continue to make its own decisions in taking or not taking action under or based upon this Agreement, any other Loan Document or any related agreement or any document furnished hereunder or thereunder.

Each of the Lenders hereby acknowledges that to the extent permitted by Applicable Law, any collateral security and the remedies provided under the Loan Documents to the Lenders are for the benefit of the Lenders collectively and acting together and not severally and further acknowledges that its rights hereunder and under any collateral security are to be exercised not severally, but by the Agent upon the decision of the Majority Lenders (or such other number or percentage of the Lenders as shall be expressly provided for in the Loan Documents). Accordingly, notwithstanding any of the provisions contained herein or in any collateral security, each of the Lenders hereby covenants and agrees that it shall not be entitled to take any action hereunder or thereunder including any declaration of default hereunder or thereunder but that any such action shall be taken only by the Agent with the prior written agreement of the Majority Lenders (or such other number or percentage of the Lenders as shall be expressly provided for in the Loan Documents). Each of the Lenders hereby further covenants and agrees that upon any

- 76 -

such written agreement being given, it shall co-operate fully with the Agent to the extent requested by the Agent. Notwithstanding the foregoing, in the absence of instructions from the Lenders and where in the sole opinion of the Agent, acting reasonably and in good faith, 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 interest of the Lenders.

17.10No Other Duties, etc.

Anything herein to the contrary notwithstanding, none of the bookrunners, arrangers or holders of similar titles, if any, specified in this Agreement shall have any powers, duties or responsibilities under this Agreement or any of the other Loan Documents, except in its capacity, as applicable, as the Agent or a Lender hereunder.

17.11Recovery of Erroneous Payments.

(a)If the Agent (x) notifies a Lender, Documentary Credit Lender, or any Person who has received funds on behalf of a Lender or Documentary Credit Lender (any such Lender, Documentary Credit Lender, or other recipient (and each of their respective successors and assigns), a “Payment Recipient”) that the Agent has determined in its sole discretion (whether or not after receipt of any notice under immediately succeeding clause (b)) that any funds (as set forth in such notice from the Agent) received by such Payment Recipient from the Agent or any of its Affiliates were erroneously or mistakenly transmitted to, or otherwise erroneously or mistakenly received by, such Payment Recipient (whether or not known to such Lender, Documentary Credit Lender, or other Payment Recipient on its behalf) (any such funds, whether transmitted or received as a payment, prepayment or repayment of principal, interest, fees, distribution or otherwise, individually and collectively, an “Erroneous Payment”) and (y) demands in writing the return of such Erroneous Payment (or a portion thereof), such Erroneous Payment shall at all times remain the property of the Agent pending its return or repayment as contemplated below in this Section 17.11 and held in trust for the benefit of the Agent, and such Lender or Documentary Credit Lender shall (or, with respect to any Payment Recipient who received such funds on its behalf, shall cause such Payment Recipient to) promptly, but in no event later than two (2) Business Days thereafter (or such later date as the Agent may, in its sole discretion, specify in writing), return to the Agent the amount of any such Erroneous Payment (or portion thereof) as to which such a demand was made, in same day funds (in the currency so received), together with interest thereon (except to the extent waived in writing by the Agent) in respect of each day from and including the date such Erroneous Payment (or portion thereof) was received by such Payment Recipient to the date such amount is repaid to the Agent in same day funds at the greater of the Prime Rate and a rate determined by the Agent in accordance with banking industry rules on interbank compensation from time to time in effect. A notice of the Agent to any Payment Recipient under this clause (a) shall be conclusive, absent manifest error.

(b)Without limiting immediately preceding clause (a), each Lender, Documentary Credit Lender, or any Person who has received funds on behalf of a Lender or Documentary Credit Lender (and each of their respective successors and assigns), agrees that if it receives a payment, prepayment or repayment (whether received as a payment, prepayment or repayment of principal, interest, fees, distribution or otherwise) from the Agent (or any of its Affiliates) (x) that is in a different amount than, or on a different date from, that specified in this Agreement or in a notice of payment, prepayment or repayment sent by the Agent (or any of its

LEGAL_1:81779606.19

BMO – BNS - Berkshire –Credit Agreement

- 77 -

Affiliates) with respect to such payment, prepayment or repayment, (y) that was not preceded or accompanied by a notice of payment, prepayment or repayment sent by the Agent (or any of its Affiliates), or (z) that such Lender, Documentary Credit Lender, or other such recipient, otherwise becomes aware was transmitted, or received, in error or by mistake (in whole or in part), then in each such case:

(i)it acknowledges and agrees that (A) in the case of immediately preceding clauses (x) or (y), an error and mistake shall be presumed to have been made (absent written confirmation from the Agent to the contrary) or (B) an error and mistake has been made (in the case of immediately preceding clause (z)), in each case, with respect to such payment, prepayment or repayment; and

(ii)such Lender or Documentary Credit Lender shall (and shall cause any other recipient that receives funds on its respective behalf to) promptly (and, in all events, within one Business Day of its knowledge of the occurrence of any of the circumstances described in immediately preceding clauses (x), (y) and (z)) notify the Agent of its receipt of such payment, prepayment or repayment, the details thereof (in reasonable detail) and that it is so notifying the Agent pursuant to this Section 17.11(b).

For the avoidance of doubt, the failure to deliver a notice to the Agent pursuant to this Section 17.11(b) shall not have any effect on a Payment Recipient’s obligations pursuant to Section 17.11(a) or on whether or not an Erroneous Payment has been made.

(c)Each Lender or Documentary Credit Lender hereby authorizes the Agent to set off, net and apply any and all amounts at any time owing to such Lender or Documentary Credit Lender under any Loan Document, or otherwise payable or distributable by the Agent to such Lender or Documentary Credit Lender under any Loan Document with respect to any payment of principal, interest, fees or other amounts, against any amount that the Agent has demanded to be returned under immediately preceding clause (a).

(d)(i) In the event that an Erroneous Payment (or portion thereof) is not recovered by the Agent for any reason, after demand therefor in accordance with immediately preceding clause (a), from any Lender that has received such Erroneous Payment (or portion thereof) (or from any Payment Recipient who received such Erroneous Payment (or portion thereof) on its respective behalf) (such unrecovered amount, an “Erroneous Payment Return Deficiency”), upon the Agent’s notice to such Lender at any time, then effective immediately (with the consideration therefor being acknowledged by the parties hereto), (A) such Lender shall be deemed to have assigned its Loans (but not its Commitments with respect to which such Erroneous Payment was made (the “Erroneous Payment Impacted Class”) in an amount equal to the Erroneous Payment Return Deficiency (or such lesser amount as the Agent may specify) (such assignment of the Loans (but not Commitments) of the Erroneous Payment Impacted Class, the “Erroneous Payment Deficiency Assignment”) (on a cashless basis and such amount calculated at par plus any accrued and unpaid interest (with the assignment fee to be waived by the Agent in such instance)), and is hereby (together with the Borrower) deemed to execute and deliver an Assignment and Assumption with respect to such Erroneous Payment Deficiency Assignment, and such Lender shall deliver any Notes evidencing such Loans to the Borrower or the Agent (but the failure of such Person to deliver any such Notes shall not affect the effectiveness of the foregoing assignment), (B) the Agent as the assignee Lender shall be deemed to have acquired the Erroneous

LEGAL_1:81779606.19

BMO – BNS - Berkshire –Credit Agreement

- 78 -

Payment Deficiency Assignment, (C) upon such deemed acquisition, the Agent as the assignee Lender shall become a Lender, as applicable, hereunder with respect to such Erroneous Payment Deficiency Assignment and the assigning Lender shall cease to be a Lender, as applicable, hereunder with respect to such Erroneous Payment Deficiency Assignment, excluding, for the avoidance of doubt, its obligations under the indemnification provisions of this Agreement and its applicable Commitments which shall survive as to such assigning Lender, (D) the Agent and the Borrower shall each be deemed to have waived any consents required under this Agreement to any such Erroneous Payment Deficiency Assignment, and (E) the Agent will reflect in the Register its ownership interest in the Loans subject to the Erroneous Payment Deficiency Assignment. For the avoidance of doubt, no Erroneous Payment Deficiency Assignment will reduce the Commitments of any Lender and such Commitments shall remain available in accordance with the terms of this Agreement.

(ii) Subject to Section 20.1 (but excluding, in all events, any assignment consent or approval requirements (whether from the Borrower or otherwise)), the Agent may, in its discretion, sell any Loans acquired pursuant to an Erroneous Payment Deficiency Assignment and upon receipt of the proceeds of such sale, the Erroneous Payment Return Deficiency owing by the applicable Lender shall be reduced by the net proceeds of the sale of such Loan (or portion thereof), and the Agent shall retain all other rights, remedies and claims against such Lender (or against any recipient that receives funds on its respective behalf). In addition, an Erroneous Payment Return Deficiency owing by the applicable Lender (x) shall be reduced by the proceeds of prepayments or repayments of principal and interest, or other distribution in respect of principal and interest, received by the Agent on or with respect to any such Loans acquired from such Lender pursuant to an Erroneous Payment Deficiency Assignment (to the extent that any such Loans are then owned by the Agent) and (y) may, in the sole discretion of the Agent, be reduced by any amount specified by the Agent in writing to the applicable Lender from time to time.

(e)The parties hereto agree that (x) irrespective of whether the Agent may be equitably subrogated, in the event that an Erroneous Payment (or portion thereof) is not recovered from any Payment Recipient that has received such Erroneous Payment (or portion thereof) for any reason, the Agent shall be subrogated to all the rights and interests of such Payment Recipient (and, in the case of any Payment Recipient who has received funds on behalf of a Lender or Documentary Credit Lender to the rights and interests of such Lender or Documentary Credit Lender as the case may be) under the Loan Documents with respect to such amount (the “Erroneous Payment Subrogation Rights”) (provided that the Borrower’s obligations under the Loan Documents in respect of the Erroneous Payment Subrogation Rights shall not be duplicative of such obligations in respect of Loans that have been assigned to the Agent under an Erroneous Payment Deficiency Assignment) and (y) an Erroneous Payment shall not pay, prepay, repay, discharge or otherwise satisfy any obligations owed by the Borrower under the Loan Documents; provided that this Section 17.11 shall not be interpreted to increase (or accelerate the due date for), or have the effect of increasing (or accelerating the due date for), the Obligations of the Borrower relative to the amount (or timing for payment) of the Obligations that would have been payable had such Erroneous Payment not been made by the Agent; provided, further, that for the avoidance of doubt, immediately preceding clauses (x) and (y) shall not apply to the extent any such Erroneous Payment is, and solely with respect to the amount of such Erroneous Payment that is, comprised of funds

LEGAL_1:81779606.19

BMO – BNS - Berkshire –Credit Agreement

- 79 -

received by the Agent from the Borrower for the purpose of making such Erroneous Payment.

(f)To the extent permitted by applicable law, no Payment Recipient shall assert any right or claim to an Erroneous Payment, and hereby waives, and is deemed to waive, any claim, counterclaim, defense or right of set-off or recoupment with respect to any demand, claim or counterclaim by the Agent for the return of any Erroneous Payment received, including any defense based on “discharge for value” or any similar doctrine.

(g)Each party’s obligations, agreements and waivers under this Section 17.11 shall survive the resignation or replacement of the Agent, any transfer of rights or obligations by, or the replacement of, a Lender or Documentary Credit Lender, the termination of the Commitments or the repayment, satisfaction or discharge of all obligations (or any portion thereof) under any Loan Document.
