2.7 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 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 willful 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 canceled at the respective maturities. Each Lender agrees to provide such records to the Borrower at the Borrower's expense upon request.

LEGAL_l:28867748.6

-17-

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 4.1 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 paragraph 2.7(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 crediting the Borrower's Account with such amount.

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 (2) 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 Proportionate Share 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 2.4 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) 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

LEGAL_l:28867748.6

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 crediting the Borrower's Account prior to 12:00 p.m. 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 Facilities 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 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 Subsection 2. 7(e) 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 Credit Documents

2.8 Letters of Credit

(a) As provided under Section 2.4, a Borrowing Notice for a Borrowing by way of Letter of Credit shall be in the form required by the Letter of Credit Lender.

The Agent will use all reasonable efforts to coordinate the obtaining of U.S. Dollars on the London interbank eurocurrency market and to quote LIBOR Rates on request of the Borrower from time to time. If at any time prior to the proposed commencement of a LIBOR Interest Period the Agent shall determine (which determination shall be made in good faith and shall be conclusive and binding) that by reason of circumstances affecting the London interbank eurocurrency market or the position of the Majority Lenders therein (i) adequate and reasonable means do not exist for ascertaining the LIBOR Rate to be applicable during such LIBOR Interest Period, or (ii) U.S. Dollars for such LIBOR Interest Period are not readily available to the Lenders, as the case may be, in the London interbank eurocurrency market, then the Agent shall give notice thereof to the Borrower prior to 10:30 a.m. on the day which is two (2) Business Days in advance of the proposed commencement of such LIBOR Interest Period, and such Loan, if not then outstanding as a LIBOR Loan, shall not be made and, if then outstanding as a LIBOR Loan, the Borrower shall then give a Notice of Borrowing in accordance with Section 2.4 converting the LIBOR Loan on the expiration of the then applicable LIBOR Interest Period to another Accommodation.

(c) If no notice is given by the Borrower as provided in paragraph (a) or (b) above, the LIBOR Loan will be automatically converted on the expiration of the then applicable LIBOR Interest Period to a U.S. Base Rate Loan, without prejudice to the Lenders' rights in respect of the failure to give the notice and whether or not a Default or Event of Default has occurred, in the principal amount of the funds required to be provided to the Agent for the account of the Lenders pursuant to this Section.

(iv) if the Agent determines that the amount of a Lender's Proportionate Share of the LIBOR Loan would not be a whole multiple of One Hundred Thousand U.S. Dollars (U.S.$100,000), the amount to be advanced by that Lender may be increased or reduced by the Agent in its sole discretion to the nearest whole multiple of One Hundred Thousand U.S. Dollars (U.S.$100,000).

2.10 Safekeeping of Drafts

The responsibility of the Agent and the Lenders in respect of the safekeeping of Drafts, Bankers' Acceptances and other bills of exchange which are delivered to any of them hereunder shall be limited to the exercise of the same degree of care which such party gives to its own property, provided that such party shall not be deemed to be an insurer thereof.

ARTICLE 6

PAYMENTS AND INDEMNITIES

6.1 Payments on Non-Business Days

Unless otherwise provided herein, whenever any payment to be made under this Agreement shall be stated to be due on a day which is not a Business Day, the due date thereof shall be extended to the next succeeding Business Day, and interest or fees shall be payable at the appropriate rate during such extension.

6.2 Method and Place of Payment

Unless otherwise provided herein, all payments made by the Borrower to the Agent under this Agreement will be made not later than 2:00 p.m. (Toronto, Ontario time) on the date when due, and all such payments will be made in immediately available funds. Any amounts received after that time shall be deemed to have been received by the Agent on the next Business Day.

6.3 Net Payments

All payments by the Borrower under this Agreement shall be made without set-off or counterclaim or other deduction and without regard to any equities between the Borrower and the Agent or any of the Lenders or any other Person and free and clear of, and without reduction for or on account of, any present or future levies, imposts, duties, charges, fees, deductions or other withholdings, and if the Borrower is required by law to withhold any amount, then the Borrower will increase the amount of such payment to an amount which will ensure that the Agent receives the full amount of the original payment.

6.4 Agent May Debit Account

The Agent may debit any accounts of the Borrower with the Agent for any payment or amount due and payable by the Borrower pursuant to this Agreement without further direction from the Borrower to the Agent; provided that any such debit is not in conflict with the provisions of the

LEGAL_l:28867748.6

-30-

Trust Indenture but in any event such debits may be made in accordance with the Agent's centralized cash management arrangements with the Borrower.

6.5 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.

If after the date of this Agreement any change in any law, regulation, treaty, directive, reserve or special deposit requirement or in the interpretation or application thereof by any court or administrative or governmental authority charged with the administration thereof, or compliance by a Lender with any request or directive (whether or not having the force oflaw) by any central bank, reserve board, superintendent of financial institutions, fiscal, monetary or other comparable authority shall:

(a) subject the Lender to any tax of any kind whatsoever with respect to this Agreement or any Accommodation or change the basis of taxation of payments to the Lender of principal, interest, fees or any other amount payable under this Agreement (except for changes in the rate of tax on the overall net income of the Lender or capital tax imposed by the laws of Canada or any political subdivision thereof or taxing authority therein); or

(b) impose, modify or make applicable any capital adequacy, reserve, assessment, special deposit or loans or similar requirement against assets held by, or deposits or other liabilities in or for the account of, or Loans or other Accommodation, credit facilities or commitments made available by, or any other acquisition of funds by, the Lender;

and the result of any of the foregoing is to impose or increase the cost to the Lender of making or maintaining any part of the Credit Facilities or any Accommodation or to reduce any amount receivable by the Lender under this Agreement with respect thereto, then, in any such case, the

LEGAL_l:28867748.6

-31-

Borrower shall pay to the Agent for the account of the relevant Lender within thirty (30) days after the date of demand by the Agent such additional amounts necessary to fully compensate the Lender for such additional cost or reduced amount receivable. If a Lender becomes entitled to claim any additional amounts pursuant to this Section, the Agent shall promptly upon receipt of particulars from the relevant Lender notify the Borrower of the event by reason of which the Lender has become so entitled and provide the Borrower with an explanation of the manner in which the liability of the Borrower under this Section has been determined. A certificate of the Lender as to any such additional amounts payable to it shall be prima facie evidence of the amount due.

6.7 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;

(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 Subsection 5.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.

6.8 Early Termination of LIBOR Interest Period

Without limiting Section 6. 7, 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.

6.9 Outstanding Bankers' Acceptances and Letters of Credit

If the Credit Facility is terminated at any time prior to the maturity date of any Bankers' Acceptance or Letter of Credit issued hereunder, the Borrower shall pay to the Lenders, on demand, an amount with respect to each such Bankers' Acceptance or Letter of Credit 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 or Letter of Credit and having in each case a term to maturity similar to the period from such demand to maturity of such Bankers' Acceptance or Letter of Credit. Upon payment by the Borrower as required under this paragraph, the Borrower shall have no further liability in respect of each such Bankers' Acceptance or Letter of Credit 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 or Letter of Credit and the Lenders shall indemnify and hold harmless the Borrower in respect of all amounts which the Borrower may be required to pay under each such Bankers' Acceptance or Letter of Credit to any party other than the Lenders.

6.10 Replacement of Lender

(a) require such Lender to assign its full Commitment under which such Advances were made (such commitments being the "Affected Commitments") and all outstanding Advances thereunder, to one or more assignees identified by the Borrower and acceptable to the Agent, acting reasonably, the assignment(s) to which assignee(s) shall have been made in accordance with Section 12.14; or

(b) terminate the Affected Commitments and repay to such Lender any Advances outstanding thereunder to the extent such Affected Commitments and Advances thereunder are not assigned pursuant to Subsection 0.XX(a).

ARTICLE 11

EVENTS OF DEFAULT

LEGAL_l:28867748.6

-41-

11.2 Remedies

Upon the occurrence of any Default or Event of Default, and at any time thereafter if the Default or Event of Default shall then be continuing, the Lenders in their sole discretion may direct the Agent to give notice to the Borrower that no further Accommodation will be available hereunder while the Default or Event of Default continues, whereupon the Lenders shall not be obliged to provide any further Borrowings to the Borrower while the Default or Event of Default continues. Upon the occurrence of any Event of Default, and at any time thereafter if the Event of Default shall then be continuing, the Lenders in their sole discretion, and the Agent acting on their behalf, may take any or all of the following actions:

(a) demand payment of any principal, accrued interest, fees and other amounts which are then due and owing in respect of the Accommodation under the Credit Facilities without presentment, protest or other notice of any kind, all of which are hereby expressly waived by the Borrower;

(b) declare by notice to the Borrower the Credit Facilities terminated, whereupon the same shall terminate immediately without any further notice of any kind;

(c) demand payment of the Pledged Bond in accordance with the provisions of the Bond Delivery Agreement; and

11.5 Non-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 11.3 in connection with such obligations.

11.6 Waiver

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 13.10. 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

LEGAL_l:28867748.6

-42-

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.

11.7 Set-off

Each of the Agent and any Lender with whom the Borrower maintains any account or accounts shall enter into an agreement with the Trustee, in form and substance satisfactory to the Trustee, pursuant to which the Agent or such Lender, as applicable, confirms to the Trustee that:

(a) in respect of any Funds and Accounts (as defined in the Trust Indenture) forming part of the Collateral (as defined in the Trust Indenture), the Trustee has a security interest in such Funds and Accounts and the cash on deposit therein are Permitted Investments forming part thereof;

(b) the Agent or such Lender, as applicable, has and will have no security interest in any such Fund or Account or the cash on deposit therein or Permitted Investments forming part thereof; and

(c) the only rights of set-off which may be exercised by the Agent or such Lender in respect of any such Fund or Account or the cash on deposit therein or Permitted Investments forming part thereof are those arising out of the operation of the relevant account unless the Agent or such Lender has agreed to remit all amounts so set-off to the Trustee to be dealt with in accordance with the Trust Indenture;

provided that none of the foregoing shall apply to rights of set-off exercised by the Agent in the ordinary course of the operation of the Agents' centralized cash management system with the Borrower.

Upon the occurrence of an Event of Default and a demand by the Agent for payment pursuant to Section 11.3, the Agent and each Lender is hereby authorized by the Borrower at any time and from time to time with notice to the Borrower to combine, consolidate and merge on behalf of the Trustee for the benefit of the Bondholders (as defined in the Trust Indenture) all or any of the Borrower's accounts with liabilities to the Agent or such Lender and to set-off, appropriate and apply on behalf of the Trustee for the benefit of such bondholders or to otherwise seize and remit to the Trustee any and all deposits by or for the benefit of the Borrower with any branch of the Agent or such Lender, general or special, matured or unmatured, and any other indebtedness and liability of the Agent or such Lender to the Borrower, matured or unmatured, against and on account of the indebtedness of the Borrower hereunder when due, notwithstanding that the balances of such accounts, deposits or indebtedness may or may not be expressed in the same currency.

ARTICLE 12

THE AGENT AND THE LENDERS

12.1 Authorization of Agent and Relationship

Each Lender hereby appoints BNS as Agent and BNS hereby accepts such appointment. The appointment may only be terminated as expressly provided in this Agreement. Each Lender hereby authorizes the Agent to take all action on· its behalf and to exercise such powers and perform such duties under this Agreement as are expressly delegated to the Agent by its terms, together with

LEGAL_l:28867748.6

-43-

all powers reasonably incidental thereto. Except as expressly specified in this Agreement, the Agent shall have only those duties and responsibilities of a solely mechanical and administrative nature that are expressly delegated to the Agent by this Agreement or are reasonably incidental thereto. The Agent may perform such duties by or through its agents or employees, but shall not by reason of this Agreement have a fiduciary duty in respect of any Lender. As to any matters not expressly provided for by this Agreement, the Agent is not required to exercise any discretion or to take any action, but is required to act or to refrain from acting (and is fully protected in so acting or refraining from acting) upon the instructions of the Lenders or the Majority Lenders, as the case may be. Those instructions shall be binding upon all Lenders, but the Agent is not required to take any action which exposes the Agent to personal liability or which is contrary to this Agreement or applicable law.

12.2 Disclaimer of Agent

The Agent makes no representation or warranty, and assumes no responsibility with respect to the due execution, legality, validity, sufficiency, enforceability or collectability of this Agreement or any other Credit Document. The Agent assumes no responsibility for the financial condition of the Borrower, or for the performance of its obligations under this Agreement or any other Credit Document. The Agent assumes no responsibility with respect to the accuracy, authenticity, legality, validity, sufficiency or enforceability of any documents, papers, materials or other information furnished by the Borrower to the Agent on behalf of the Lenders. The Agent shall not be required to ascertain or inquire as to the performance or observance of any of the terms, conditions, provisions, covenants or agreements contained herein or as to the use of the proceeds of any credit hereunder or (unless the officers or employees of the Lender acting as Agent active in their capacity as officers or employees on the Borrower's accounts have actual knowledge thereof, or have been notified thereof in writing by the Borrower or a Lender) of the existence or possible existence of any Default or Event of Default. Neither the Agent nor any of its directors, officers, agents or employees shall be liable for any action taken or omitted to be taken by it or them as Agent under or in connection with the Agreement, whether in the good faith exercise of any discretion expressly granted to the Agent or otherwise, except for actions or omissions arising from its or their own negligence or wilful misconduct. With respect to its Commitment, the Lender acting as Agent shall have the same rights and powers hereunder as any other Lender, and may exercise the same as though it were not performing the duties and functions delegated to it as Agent hereunder.

12.3 Failure of Lender to Fund

(a) Unless the Agent has actual knowledge that a Lender has not made or will not make available to the Agent for value on a Borrowing Date the applicable amount required from such Lender pursuant to Article 2, the Agent shall be entitled to assume that such amount has been or will be received from such Lender when so due and the Agent may (but shall not be obliged to), in reliance upon such assumption, make available to the Borrower a corresponding amount. If such amount is not in fact received by the Agent from such Lender on such Borrowing Date and the Agent has made available a corresponding amount to the Borrower on such Borrowing Date as aforesaid, such Lender shall pay to the Agent on demand an amount equal to the product of (i) the rate per annum then in use at the Branch as a syndicate lender late payment rate, multiplied by (ii) the amount that should have been paid to the Agent by such Lender on such Borrowing Date and was not, multiplied by (iii) a fraction, the numerator of which is the number of days that have elapsed from

LEGAL_l:28867748.6

-44-

and including such Borrowing Date to but excluding the date on which the amount is received by the Agent from such Lender and the denominator of which is three hundred and sixty-five (365). A certificate of the Agent containing details of the amount owing by a Lender under this Section shall be binding and conclusive in the absence of manifest error. If any such amount is not in fact received by the Agent from such Lender on such Borrowing Date, the Agent shall be entitled to recover from the Borrower, on demand, the related amount made available by the Agent to the Borrower as aforesaid together with interest thereon at the applicable rate per annum payable by the Borrower hereunder.

(b) Notwithstanding the provisions of Subsection 12.3(a), if any Lender fails to make available to the Agent its Proportionate Share of any Advance (such Lender being herein called the "Defaulting Lender"), the Agent shall forthwith give notice of such failure by the Defaulting Lender to the other Lenders. The Agent shall then forthwith give notice to the other Lenders that any Lender may make available all or any portion of the Defaulting Lender's share of such Advance in the place of the Defaulting Lender, but in no way shall any other Lender or the Agent be obliged to do so. If more than one Lender gives notice that it is prepared to make funds available in the place of a Defaulting Lender in such circumstances and the aggregate of the funds which such Lenders (herein collectively called the "Contributing Lenders" and individually called the "Contributing Lender") are prepared to make available exceeds the amount of the Advance which the Defaulting Lender failed to make, then each Contributing Lender shall be deemed to have given notice that it is prepared to make available a portion of such Advance based on the Contributing Lenders' relative Proportionate Shares. If any Contributing Lender makes funds available in the place of a Defaulting Lender in such circumstances, then the Defaulting Lender shall pay to any Contributing Lender making the funds available in its place, forthwith on demand any amount advanced on its behalf together with interest thereon at the rate applicable to such Advance from the date of advance to the date of payment, against payment by the Contributing Lender making the funds available of all interest received in respect of the Advance from the Borrower. The failure of any Lender to make available to the Agent its Proportionate Share of any Advance as required herein shall not relieve any other Lender of its obligations to make available to the Agent its Proportionate Share of any Advance as required herein.

12.4 Payments by the Borrower

Unless otherwise expressly provided in this Agreement as among the Lenders, all payments made by or on behalf of the Borrower pursuant to this Agreement shall be made to and received by the Agent and shall be distributed by the Agent to the Lenders as soon as possible upon receipt by the Agent. Subject to any other provision of this Agreement concerning the distribution of payments, the Agent shall cause distribution of:

(a) payments of interest in accordance with each Lender's Advanced Share of the Advances to which the payment relates;

(b) repayments of principal in accordance with each Lender's Advanced Share of the Advances to which the payment relates;

LEGAL_l:28867748.6

-45-

(c) payments of standby fees in accordance with Section 4.3;

(d) all other payments including, without limitation, amounts received upon realization, in accordance with each Lender's Proportionate Share; provided, however, that with respect to proceeds of realization, no Lender shall receive an amount in excess of the amounts owing to it in respect of the Accommodations.

Subject to Section 12.5, if the Agent does not distribute a Lender's share of a payment made by the Borrower to that Lender for value on the day that payment is made or deemed to have been made to the Agent, the Agent shall pay to the Lender on demand an amount equal to the product of (i) the rate per annum then in use at the Branch as a syndicate lender late payment rate, multiplied by (ii) the Lender's share of the amount received by the Agent from the Borrower and not so distributed, multiplied by (iii) a fraction, the numerator of which is the number of days that have elapsed from and including the date of receipt of the payment by the Agent to but excluding the date on which the payment is made by the Agent to such Lender and the denominator of which is three hundred and sixty-five (365).

12.5 Payments by Agent

(a) For greater certainty, the following provisions shall apply to any and all payments made by the Agent to the Lenders hereunder:

(i) the Agent shall be under no obligation to make any payment (whether in respect of principal, interest, fees or otherwise) to any Lender until an amount in respect of such payment has been received by the Agent from the Borrower;

(ii) if the Agent receives less than the full amount of any payment of principal, interest, fees or other amount owing by the Borrower under this Agreement, the Agent shall have no obligation to remit to each Lender any amount other than such Lender's share of that amount which is actually received by the Agent;

(iii) if a Lender's share of an Advance has been advanced, or a Lender's Commitment has been outstanding, for less than the full period to which any payment (other than a payment of principal) by the Borrower relates, such Lender's entitlement to such payment shall be reduced in proportion to the length of time such Lender's share of the Advance or such Lender's Commitment, as the case may be, has actually been outstanding;

(iv) the Agent acting reasonably and in good faith shall, after consultation with the Lenders in the case of any dispute, determine in all cases the amount of all payments to which each Lender is entitled and such determination shall, in the absence of manifest error, be binding and conclusive; and

(v) upon request, the Agent shall deliver a statement detailing any of the payments to the Lenders referred to herein.

LEGAL_l:28867748.6

-46-

(b) Unless the Agent has actual knowledge that the Borrower has not made or will not make a payment to the Agent for value on the date in respect of which the Borrower has notified the Agent that the payment will be made, the Agent shall be entitled to assume that such payment has been or will be received from the Borrower when due and the Agent may (but shall not be obliged to), in reliance upon such assumption, pay the Lenders corresponding amounts. If the payment by the Borrower is in fact not received by the Agent on the required date and the Agent has made available corresponding amounts to the Lenders, the Borrower shall, without limiting its other obligations under this Agreement, indemnify the Agent against any and all liabilities, obligations, losses, damages, penalties, costs, expenses or disbursements of any kind or nature whatsoever that may be imposed on or incurred by the Agent as a result. A certificate of the Agent with respect to any amount owing by the Borrower under this Section shall be prima facie evidence of the amount owing in the absence of manifest error. The Agent shall be entitled to recover from each Lender to which a payment is made in reliance on the expectation of payment from the Borrower in accordance with this Section, the full amount of such payment that is not recovered from the Borrower, together with interest at the rate per annum then in use at the Branch as a syndicate lender late payment rate, from the date on which payment is made by the Agent to the date on which repayment is made by the Lender receiving such payment.

12.6 Direct Payments

The Lenders agree among themselves that, except as otherwise provided for in this Agreement, all sums received by a Lender relating to this Agreement whether received by voluntary payment, by the exercise of the right of set-off or compensation or by counterclaim, cross-action or otherwise, shall be shared by each Lender so that the ultimate exposure of each Lender is in accordance with its Advanced Share of all Advances under this Credit Facility, and each Lender undertakes to do all such things as may be reasonably required to give full effect to this Section, including without limitation, the purchase from other Lenders of their proportionate interest in the Borrowings by the Lender who has received an amount in excess of its Proportionate Share of amounts advanced under this Credit Facility as shall be necessary to cause such purchasing Lender to share the excess amount rateably with the other Lenders to the extent of their Advanced Share of any Advances under this Credit Facility. If any Lender shall obtain any payment of moneys due under this Agreement as referred to above, it shall forthwith remit such payment to the Agent and, upon receipt, the Agent shall distribute such payment in accordance with the provisions of Section 12.5.

12.7 Administration of the Credit Facilities

(a) Unless otherwise specified herein, the Agent shall perform the following duties under this Agreement:

(i) prior to a Borrowing, ensure that all conditions precedent have been fulfilled in accordance with the terms of this Agreement, subject to Subsection 12.8(b) and any other applicable terms of this Agreement;

(ii) use reasonable efforts to collect promptly all sums due and payable by the Borrower pursuant to this Agreement;

LEGAL_l:28867748.6

-47-

(iii) hold all legal documents relating to the Credit Facilities, maintain complete and accurate records showing all Advances made by the Lenders, all remittances and payments made by the Borrower to the Agent, all remittances and payments made by the Agent to the Lenders and all fees or any other sums received by the Agent and, except for accounts, records and documents relating to the fees payable under any separate fee agreement, allow each Lender and their respective advisers to examine such accounts, records and documents at their own expense, and provide any Lender, upon reasonable notice, with such copies thereof as such Lender may reasonably require from time to time at the Lender's expense;

(iv) except as otherwise specifically provided for in this Agreement, promptly advise each Lender upon receipt of each notice and deliver to each Lender, promptly upon receipt, all other written communications furnished by the Borrower to the Agent on behalf of the Lenders pursuant to this Agreement, including without limitation copies of financial reports and certificates which are to be furnished to the Agent;

(v) forward to each of the Lenders, upon request, copies of this Agreement, and other Credit Documents (other than any separate fee agreement);

(vi) promptly forward to each Lender, upon request, an up-to-date loan status report; and

(vii) upon learning of same, promptly advise each Lender in writing of the occurrence of an Event of Default or Default or the occurrence of any event, condition or circumstance which would have a Material Adverse Effect on the ability of the Borrower to comply with this Agreement or of the occurrence of any material adverse change on the business, operations or assets of the Borrower, taken as a whole, provided that, except as aforesaid, the Agent shall be under no duty or obligation whatsoever to provide any notice to the Lenders and further provided that each Lender hereby agrees to notify the Agent of any Event of Default or Default of which it may reasonably become aware.

(b) The Agent may take the following actions only with the prior consent of the Majority Lenders, unless otherwise specified in this Agreement:

(i) subject to Subsection 12.7(c), exercise any and all rights of approval conferred upon the Lenders by this Agreement;

(ii) amend, modify or waive any of the terms of this Agreement (including waiver of an Event of Default or Default) if such amendment, modification or waiver would have a Material Adverse Effect on the rights of the Lenders thereunder and if such action is not otherwise provided for in Subsection 12.7(c);

(c) The Agent may take the following actions only if the prior unanimous consent of the Lenders is obtained, unless otherwise specified herein:

(ii) amend the definition of"Majority Lenders" or this Subsection 12.7(c).

(d) Notwithstanding Subsection 12.7(b) and any other provision of this Agreement except for Subsection 12.7(c), 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 to protect the interests of the Lenders, the Agent may without notice to or consent of the Lenders take such action on behalf of the Lenders as the Agent deems appropriate or desirable.

(e) As between the Borrower, the Agent and the Lenders:

(i) all statements, certificates, consents and other documents which the Agent purports to deliver on behalf of the Lenders or the Majority Lenders shall be binding on each of the Lenders, and the Borrower shall not be required to ascertain or confirm the authority of the Agent in delivering such documents;

(ii) all certificates, statements, notices and other documents which are delivered by the Borrower to the Agent in accordance with this Agreement shall be deemed to have been duly delivered to each of the Lenders, except where this Agreement expressly requires delivery of notices of Advances and payments to the Agent and/or individual Lenders;
