2.5 Borrowing Notice.

Whenever the Borrower desires to obtain a Borrowing (other than in the case of a Documentary Credit) it shall give to the Agent prior written notice in the form attached as Schedule 2(A), (B) or (C), as applicable (each, a "Borrowing Notice"), specifying, as applicable:


(i)	the amount, currency and type or types of Accommodation desired;


(ii)	the details of the account of the Borrower to which payment of the Borrowing is to be wired or otherwise made, if applicable;


(iii)	the requested Borrowing Date;


(iv)	if such Borrowing includes a Bankers' Acceptance, the term thereof;

(vii)	if such Borrowing includes a LIBOR Loan, the LIBOR Interest Period to be applicable to such Loan.

The Borrowing Notice shall be given to the Agent not later than 10:00 a.m.:

RBC-AltaLink-Amended and Restated Credit Agreement

LEGAL_1:22094689.5

-27-

repaid and all other amounts from time to time owing by the Borrower to the Lenders under this Agreement including interest, acceptance, Documentary Credits and standby and other fees, and to enter into such books and records details of all amounts from time to time owing, paid or repaid by the Borrower under this Agreement. The Borrower acknowledges, confirms and agrees with the Agent that all such books and records kept by the Agent will constitute prima facie evidence of the balance owing by the Borrower under this Agreement; provided, however, that the failure to make any entry or recording in such books and records shall not limit or otherwise affect the obligations of the Borrower under this Agreement. Notwithstanding the foregoing, each Lender is responsible for maintaining its own records as to Advances made by it, and in the event of any inconsistency between such Lender's and the Agent's records, the Agent's records shall govern, absent manifest error.

2.7 Co-ordination of Prime Rate and U.S. Base Rate Loans.

Each Lender shall advance its Applicable Percentage of each Prime Rate and U.S. Base Rate Loan in accordance with the following provisions:


(a)	the Agent shall advise each Lender of its receipt of a notice from the Borrower pursuant to Section 2.5, on the day such notice is received and shall, as soon as possible, advise each Lender of such Lender's Applicable Percentage of any Prime Rate or U.S. Base Rate Loan requested by the notice;


(b)	each Lender shall deliver its Applicable Percentage of such Loan to the Agent's Account at the Branch not later than 11 :00 a.m. on the Borrowing Date;

(c)

when the Agent determines that all the conditions precedent to a Borrowing specified in this Agreement have been met or waived, it shall advance to the Borrower the amount delivered by each Lender by wiring such amount to relevant account of the Borrower before 12:00 noon on the Borrowing Date, but if the conditions precedent to the Borrowing are not met or waived by such time, the Agent shall return the funds to the Lenders or invest them in an overnight investment as orally instructed by each Lender until such time as the Loan is advanced.

2.8 Bankers' Acceptances.

(a)

Power of Attorney for the Execution of Bankers' Acceptances. To facilitate acceptance of the Borrowings by way of Bankers' Acceptances, the Borrower hereby appoints each Lender as its attorney to sign and endorse on its behalf, in handwriting or by facsimile or mechanical signature as and when deemed necessary by such Lender, blank forms of Drafts. In this respect, it is each Lender's responsibility to maintain an adequate supply of blank forms of Drafts for acceptance under this Agreement. The Borrower recognizes and agrees that all Drafts signed and/or endorsed on its behalf by a Lender shall bind the Borrower fully and effectively as if signed in the handwriting of and duly issued by the proper signing officers of the Borrower. Each Lender is hereby authorized to issue such Drafts endorsed in blank in such face amounts as may be determined by such Lenders; provided that the aggregate amount thereof is equal to the aggregate

RBC-AltaLink-Amended and Restated Credit Agreement

LEGAL_1:22094689.5

-28-

amount of Bankers' Acceptances required to be accepted and purchased by such Lender. No Lender shall be liable for any damage, loss or other claim arising by reason of any loss or improper use of any such instrument, except the gross negligence or wilful misconduct of the Lender or its officers, employees, agents or representatives. Each Lender shall maintain a record with respect to Bankers' Acceptances held by it in blank hereunder, voided by it for any reason, accepted and purchased by it hereunder, and cancelled at the respective maturities. Each Lender agrees to provide such records to the Borrower at the Borrower's expense upon request.

Drafts drawn by the Borrower to be accepted as Bankers' Acceptances shall be signed by a duly authorized officer or officers of the Borrower or by its attorneys. Notwithstanding that any Person whose signature appears on any Bankers' Acceptance may no longer be an authorized signatory for the Borrower at the time of issuance of a Bankers' Acceptance; that signature shall nevertheless be valid and sufficient for all purposes as if the authority had remained in force at the time of issuance and any Bankers' Acceptance so signed shall be binding on the Borrower. Upon tender of each Draft the Borrower shall pay to the Lender the fee specified in Section 5.1 with respect to such Draft.


(b)	Sale of Bankers' Acceptances. It shall be the responsibility of each Lender unless otherwise requested by the Borrower, to purchase its Bankers' Acceptances at a discount rate equal to the BA Discount Rate.

In accordance with the procedures set forth in Sections 2.8(c)(i) and 2.8(c)(iii), unless the Borrower requests the Lenders not to purchase the subject Bankers' Acceptances, the Agent will make BA Discount Proceeds received by it from the Lenders available to the Borrower on the Borrowing Date by wiring such amount to the bank account of the Borrower identified to the Agent.

Notwithstanding the foregoing, if in the determination of the Majority Lenders acting reasonably a market for Bankers' Acceptances does not exist at any time, or the Lenders collectively cannot for other reasons readily sell Bankers' Acceptances or perform their other obligations under this Agreement with respect to Bankers' Acceptances, then upon at least two Business Days' written notice by the Agent to the Borrower, the Borrower's right to request Accommodation by way of Bankers' Acceptances shall be and remain suspended until the Agent notifies the Borrower that any condition causing such determination no longer exists.


(c)	Coordination of BA Borrowings. Each Lender shall advance its Applicable Percentage of each Borrowing by way of Bankers' Acceptances in accordance with the following:


(i)	the Agent, promptly following receipt of a notice from the Borrower pursuant to Section 2.5 requesting a Borrowing by way of Bankers' Acceptances, shall advise each Lender of the aggregate Face Amount and term(s) of the Bankers' Acceptances to be accepted by it, which term(s)

RBC-AltaLink-Amended and Restated Credit Agreement

LEGAL_1:22094689.5

-29-

shall be identical for all Lenders. The aggregate Face Amount of Bankers' Acceptances to be accepted by a Lender shall be determined by the Agent by reference to the respective Commitments of the Lenders, except that, if the Face Amount of a Bankers' Acceptance would not be One Hundred Thousand Canadian Dollars (Cdn.$100,000) or a whole multiple thereof, the Face Amount shall be increased or reduced by the Agent in its sole discretion to the nearest whole multiple of One Hundred Thousand Canadian Dollars (Cdn.$100,000);

(ii)

unless requested by the Borrower not to purchase the subject Bankers' Acceptances, each Lender shall transfer to the Agent at the Branch for value on each Borrowing Date immediately available Canadian Dollars in an aggregate amount equal to the BA Discount Proceeds of all Bankers' Acceptances accepted and sold or purchased by the Lender on such Borrowing Date, net of the applicable Bankers' Acceptance Fees in respect of such Bankers' Acceptances. Each Lender shall also advise the Agent (which shall promptly give the relevant particulars to the Borrower) as soon as possible of the discount rate at which it has sold or purchased its Bankers' Acceptances;


(iii)	if the Borrower requests the Lenders not to purchase the subject Bankers' Acceptances, each Lender will forward the subject Bankers' Acceptances to the Agent for delivery against payment of the applicable Bankers' Acceptance Fees; and

(iv)

if the Agent determines that all the conditions precedent to a Borrowing specified in this Agreement have been met or waived, it shall advance to the Borrower the amount delivered by each Lender by wiring such amount to the account of the Borrower prior to 12:00 noon on the Borrowing Date, or, if applicable shall deliver the Bankers' Acceptances as directed by the Borrower, but if the conditions precedent to the Borrowing are not met or waived by 2:30 p.m. on the Borrowing Date, the Agent shall return the funds to the Lenders or invest them in an overnight investment as orally instructed by each Lender until such time as the Advance is made.

(d)

Payment. The Borrower shall provide for the payment to the Agent for the account of the Lenders of the Face Amount of each Bankers' Acceptance at its maturity, either by payment of the amount thereof or through utilization of the Credit Facility in accordance with this Agreement (by rolling over the Bankers' Acceptance or converting it into other Accommodation or a combination thereof). The Borrower will continue to be required to provide as aforesaid for each Bankers' Acceptance at maturity notwithstanding the fact that a Lender may be the holder of the Bankers' Acceptance which has been accepted by such Lender.


(e)	Collateralization.


(i)	If any Bankers' Acceptance is outstanding on the Demand Date or the Maturity Date, the Borrower shall on such date pay to the Agent for the

RBC-AltaLink-Amended and Restated Credit Agreement

account of the Lenders at the Branch in Canadian Dollars an amount equal to the Face Amount of such Bankers' Acceptance.

(ii)

All funds received by the Agent pursuant to Section 2.8(e)(i) shall be held by the Agent for set-off on the maturity date of the Bankers' Acceptance against the liability of the Borrower to the Lender in respect of such Bankers' Acceptance and, until then, shall be invested from time to time in such form of investment at the Branch designated by the Borrower and approved by the Agent, for a term corresponding to the maturity date of the applicable Bankers' Acceptance and shall bear interest at the rate payable by the Agent on deposits of similar currency, amount and maturity. The balance of all such funds (together with interest thereon) held by the Agent will be applied to repayment of all debts and liabilities of the Borrower to the Lender under this Agreement and the Loan Documents and following repayment of all such debts and liabilities any amount remaining shall be paid to the Borrower or as otherwise required bylaw.


(f)	Notice of Rollover or Conversion. The Borrower shall give the Agent notice in the form attached as Schedule 2(B) or Schedule 2(C) hereto, as applicable, not later than 11:00 a.m. on the Business Day prior to the maturity date of Bankers' Acceptances, specifying the Accommodation into which the Bankers' Acceptances will be renewed or converted on maturity.

The obligations of the Borrower with respect to Bankers' Acceptances under this Agreement shall be unconditional and irrevocable, and shall be paid strictly in accordance with the terms of this Agreement under all circumstances, including, without limitation, the following circumstances:


(i)	any lack of validity or enforceability of any Draft accepted by a Lender as a Bankers' Acceptance; or


(ii)	the existence of any claim, set-off, defence or other right which the Borrower may have at any time against the holder of a Bankers' Acceptance, a Lender or any other person or entity, whether in connection with this Agreement or otherwise.


(h)	Shortfall on Drawdowns, Rollovers and Conversions. The Borrower agrees that the difference between the:


(i)	amount of a Borrowing requested by the Borrower by way of Bankers' Acceptances and the actual proceeds of the Bankers' Acceptances;


(ii)	actual proceeds of a Bankers' Acceptance and the amount required to pay a maturing Bankers' Acceptance if a Bankers' Acceptance is being rolled over; and

LEGAL_1:22094689.5

shall be funded and paid by the Borrower from its own resources, by 11 :00 a.m. (Calgary time) on the day of the Borrowing or may be advanced as a Prime Rate Loan if the Borrower is otherwise entitled to such Accommodation and the Agent will apply such Prime Rate Loan to discharge the obligations of the Borrower under such Bankers' Acceptance. Any such Prime Rate Loan so made shall be subject to the terms and provisions of this Agreement, including payment of interest at the rates specified in Section 4.1.

(i)

Depository Bills and Notes Act. At the option of any Lender (and notwithstanding Section 2.8 (a), Bankers' Acceptances under this Agreement to be accepted by that Lender may be issued in the form of Depository Bills for a deposit with the Canadian Depository for Securities Limited pursuant to the Depository Bills and Notes Act (Canada). All Depository Bills so issued shall be governed by the provisions of this Section 2.8, as applicable.

(j)

BA Equivalent Loans. Whenever the Borrower requests an Advance that includes Banker's Acceptances, each Lender that is not permitted by Applicable Law or by customary market practice to accept a Banker's Acceptance (a "Non BA Lender") shall, in lieu of accepting its pro rata amount of such Banker's Acceptances, make available to the Borrower on the Borrowing Date a non-interest bearing loan (a "BA Equivalent Loan") in Canadian Dollars in an amount equal to the BA Discount Proceeds of its pro rata amount of the Banker's Acceptances, based on the BA Discount Rate applicable to such Lender. Each Non BA Lender shall also be entitled to deduct from the BA Equivalent Loan an amount equal to the Banker's Acceptance Fee that would have been applicable had it been able to accept Banker's Acceptances. The BA Equivalent Loan shall have a term equal to the term of the Banker's Acceptances that the Non BA Lender would otherwise have accepted and the Borrower shall, at the end of that term, be obligated to pay the Non BA Lender an amount equal to the aggregate face amount of the Banker's Acceptances that it would otherwise have accepted. All provisions of this Agreement applicable to Banker's Acceptances and Lenders that accept Banker's Acceptances shall apply mutatis mutandis to BA Equivalent Loans and Non BA Lenders and, without limiting the foregoing, Accommodations shall include BA Equivalent Loans.

Thereafter, the obligation of the Lenders to make or maintain LIBOR Loans shall be suspended until the Agent revokes such

LEGAL_1:22094689.5

-32-

notice. Upon receipt of such notice of suspension, the Borrower may revoke any pending request for a LIBOR Loan, or conversion or continuation of a LIBOR Loan, or, failing that, will be deemed to have converted such request into a request for a U.S. Base Rate Loan in the amount specified therein.

The balance of all such funds (together with interest thereon) held by the Agent will be applied to repayment of all debts and liabilities of the Borrower to the Lenders under this Agreement and the Loan Documents and following repayment of all such debts and liabilities any amount remaining shall be paid to the Borrower or as otherwise required by law.


(f)	Each Lender shall advance its Applicable Percentage of each LIBOR Loan in accordance with the following provisions:

The Documentary Credit Lender may require reasonable changes in any such document or certificate.

3.3 Form of Documentary Credits.

Each Documentary Credit (i) shall be in Canadian Dollars or United States Dollars, (ii) shall be dated the Issue Date (iii) shall have an expiration date on a Business Day which occurs no more than one year after the Issue Date (provided, however, no expiration date shall be a date after the Maturity Date), and (iv) shall comply with the definition of Documentary Credit.

If any amount required to be paid by a Lender to the Documentary Credit Lender pursuant to Section (a) is not paid to the Documentary Credit Lender within two Business Days after the date the payment is due, the Lender shall pay to the Documentary Credit Lender, on demand, such amount together with interest, from the date the payment was to be made until the date it is actually made, at the prevailing interbank rate. A certificate of the Documentary Credit Lender, submitted to the relevant Lender with respect to any amounts owing under this Section shall be conclusive, absent manifest error.

(c)

If, at any time after the Documentary Credit Lender has made a payment under any Documentary Credit and has received from the Lenders their pro rata share of such payment, the Documentary Credit Lender receives a payment in respect of the Documentary Credit (whether directly from the Borrower or otherwise), the Documentary Credit Lender will distribute to the Lenders their pro rata share of such payment; provided, however, if any payment so received by the Documentary Credit Lender shall be required to be returned by the Documentary Credit Lender, each Lender shall return to the Documentary Credit Lender the portion thereof previously distributed to it.

3.6 Risk of Documentary Credits.

RBC-AltaLink-Amended and Restated Credit Agreement

LEGAL_1:22094689.5

-36-

Beneficiary under the Documentary Credit a fraudulent one, (v) payment by the Documentary Credit Lender under the Documentary Credit against presentation of a certificate or other document which does not comply with the terms of the Documentary Credit, unless such payment is inconsistent with the standards of reasonable care specified in the Uniform Customs and Practice for Documentary Credits (1993 Revision), ICC Publication 500 (or any replacement publication), or (vi) the existence of a Default or Event of Default.

(c)

The Documentary Credit Lender shall not be responsible for (i) the validity or sufficiency of any instrument transferring or assigning or purporting to transfer or assign a Documentary Credit or the rights or benefits under it or proceeds of it, in whole or in part, which may prove to be invalid or ineffective for any reason, (ii) errors, omissions, interruptions or delays in transmission or delivery of any messages by mail, facsimile or otherwise, (iii) errors in interpretation of technical terms, (iv) any loss or delay in the transmission of any document required in order to make a drawing, and (v) any consequences arising from causes beyond the control of the Documentary Credit Lender, including the acts or omissions, whether rightful or wrongful, of any Governmental Authority.

7.4 Agent May Debit Account.

The Agent may debit accounts of the Borrower with the Agent (if any) for any payment or amount due and payable by the Borrower pursuant to this Agreement without further direction from the Borrower to the Agent.

7.5 Currency of Payment.

Accommodation shall be repaid by the Borrower to the Agent or a Lender as required under this Agreement in the currency in which such Accommodation was obtained. Any payment on account of an amount payable under this Agreement in a particular currency (the "Proper Currency") required by any authority having jurisdiction to be made (or which a Lender elects to accept) in a currency (the "Other Currency") other than the Proper Currency, whether pursuant to a judgment or order of any court or tribunal or otherwise, shall constitute a discharge of the Borrower's obligations under this Agreement only to the extent of the amount of the Proper Currency which each applicable Lender is able, as soon as practicable after receipt by it of such payment, to purchase with the amount of the Other Currency so received. If the amount of the Proper Currency which a Lender is so able to purchase is less than the amount of the Proper Currency originally due to it, the Borrower shall indemnify and hold such Lender harmless from and against all losses, costs, damages or expenses which such Lender may sustain, pay or incur as a result of such deficiency. 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.

7.6 General Indemnity.

The Borrower shall indemnify the Agent and the Lenders and their directors, officers, employees, attorneys 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:


(i)	failure by the Borrower to make payment when due of the principal amount of or interest on any LIBOR Loan;


(ii)	failure by the Borrower in proceeding with a Borrowing after the Borrower has given a Borrowing Notice;

RBC-AltaLink-Amended and Restated Credit Agreement

LEGAL_1:22094689.5

-45-


(iii)	failure by the Borrower in repaying a Borrowing after the Borrower has given a notice of repayment;


(iv)	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


(v)	except as otherwise provided in Section 6.l(c)the repayment of any LIBOR Loan otherwise than on the expiration of any applicable LIBOR Interest Period or the repayment of any Bankers' Acceptance otherwise than on the maturity 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.

7.7 Early Termination of LIBOR Interest Period.

Without limiting Section 7 .6, if the Agent is required to arrange for early termination of any LIBOR Interest Period or to arrange to acquire funds for any period other than a LIBOR Interest Period to permit the Borrower to repay any LIBOR Loan, the Borrower shall reimburse the Lenders for all losses and reasonable out-of-pocket expenses incurred by them as a result of the early termination of the LIBOR Interest Period in question or as a result of entering into the new arrangement to the extent that such losses and expenses result from such payment. If any such early termination or new arrangement cannot be effected by the Agent on behalf of the Lenders, the Borrower shall continue to pay interest to the Agent in U.S. Dollars at the LIBOR Rate specified hereunder upon an amount of U.S. Dollars equal to the amount of the principal repayment for the remainder of the then current LIBOR Interest Period. 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 a Lender or Lenders as to any such loss or expense, providing details of the calculation of such loss or expense, shall be prima facie evidence.

7.8 Outstanding Bankers' Acceptances.

If the Credit Facility is terminated at any time prior to the maturity date of any Bankers' Acceptance issued hereunder, the Borrower shall pay to the Lenders, on demand, an amount with respect to each such Bankers' Acceptance equal to the total amounts which would be required to purchase in the Canadian Dollars market, as of 10:00 a.m. on the date of payment of such demand, Government of Canada treasury bills in an aggregate amount equal to the Face Amount of such Bankers' Acceptance having a term to maturity similar to the period from such demand to maturity of such Bankers' Acceptance. Upon payment by the Borrower as required under this paragraph, the Borrower shall have no further liability in respect of each such Bankers' Acceptance and the Lenders shall be entitled to all of the benefits of, and be responsible for all payments to third parties under, such Bankers' Acceptance and the Lenders shall indemnify and

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.

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 providing the Borrower with an accounting when the obligation is finally determined. Each

RBC-AltaLink-Amended and Restated Credit Agreement

LEGAL_1:22094689.5

-64-

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

13.1 Increased 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 Tax payable by such Lender; or


(iii)	impose on any Lender or any applicable interbank market any other condition, cost or expense affecting this Agreement 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.

RBC-AltaLink-Amended and Restated Credit Agreement

LEGAL_1:22094689.5

-65-

(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 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.

13.2 Taxes.

(a)

Payments Subject to Taxes. If any Credit Party, the Agent or any Lender is required by Applicable Law to deduct or pay any Indemnified Taxes (including any Other Taxes) in respect of any payment by or on account of any obligation of a Credit Party hereunder or under any other Loan Document, then (i) the sum payable shall be increased by that Credit Party when payable as necessary so that after making or allowing for all required deductions and payments (including deductions and payments applicable to additional sums payable under this Section) the Agent or Lender, as the case may be, receives an amount equal to the

RBC-AltaLink-Amended and Restated Credit Agreement

LEGAL_1:22094689.5

-66-

sum it would have received had no such deductions or payments been required, (ii) the Credit Party shall make any such deductions required to be made by it under Applicable Law and (iii) the Credit Party shall timely pay the full amount required to be deducted to the relevant Governmental Authority in accordance with Applicable Law.


(b)	Payment of Other Taxes by the Borrower. Without limiting the provisions of paragraph (1) above, the Borrower shall timely pay any Other Taxes to the relevant Governmental Authority in accordance with Applicable Law.

(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 or Other Taxes (including Indemnified Taxes or Other Taxes imposed or asserted on or attributable to amounts payable under this Section) paid by the Agent or such Lender and any penalties, interest and reasonable expenses arising therefrom or with respect thereto, whether or not such Indemnified Taxes or Other 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. A Lender shall make reasonable efforts to limit the incidence of any payments under this Section and seek recovery for the account of the Borrower upon the Borrower's request at the Borrower's expense, provided such Lender in its reasonable determination suffers no appreciable economic, legal, regulatory or other disadvantage.

(d)

Evidence of Payments. As soon as practicable after any payment of Indemnified Taxes or Other Taxes by a Credit Party to a Governmental Authority, the Credit Parties 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

RBC-AltaLink-Amended and Restated Credit Agreement

LEGAL_1:22094689.5

-67-

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 Other Taxes as to which it has been indemnified by the Borrower or with respect to which a Credit Party has paid additional amounts pursuant to this Section 13.2 or that, because of the payment of such Taxes or Other Taxes, it has benefited from a reduction in Excluded Taxes otherwise payable by it, it shall pay to the Borrower or other Credit Party, as applicable, an amount equal to such refund or reduction (but only to the extent of indemnity payments made, or additional amounts paid, by the Borrower or other Credit Party under this Section with respect to the Taxes or Other 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 or other Credit Party as applicable, upon the request of the Agent or such Lender, agrees to repay the amount paid over to the Borrower or other Credit Party (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.

13.3 Mitigation 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, if 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, if any Lender's obligations are suspended pursuant to Section 13.4 or if any Lender defaults in its obligation to fund Accommodations hereunder, then the Borrower may either, at its sole expense and effort, upon 10 days' notice

RBC-AltaLink-Amended and Restated Credit Agreement

LEGAL_1:22094689.5

-68-

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:


(i)	the Borrower pays the Agent the assignment fee specified in Section 20.l(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 Letters of Credit, 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);


(c)	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


(d)	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.

13.4 Illegality.

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

RBC-AltaLink-Amended and Restated Credit Agreement

LEGAL_1:22094689.5

-69-

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

14.1 Right 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 any Credit Party 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 Credit Party may be contingent or unmatured or are owed to a branch or 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

15.1 Sharing 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;

the provisions of this Section shall not be construed to apply to (x) any payment made by any Credit Party 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 any Credit Party or any Affiliate of a Credit Party (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 a Credit Party upon the termination of derivatives entered into between the Credit Party 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.

(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

RBC-AltaLink-Amended and Restated Credit Agreement

LEGAL_1:22094689.5

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

17.1 Appointment 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 no Credit Party shall have rights as a third party beneficiary of any of such provisions.

17.2 Rights 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 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 any Credit Party or any Affiliate thereof as if such Person were not the Agent and without any duty to account to the Lenders.

17.3 Exculpatory 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;

-72-

(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.

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

RBC-AltaLink-Amended and Restated Credit Agreement

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.
