(i) Working Capital Loans. Each US Tranche Lender severally agrees, on the terms and conditions of this Agreement, to make Working Capital Loans to the US Borrower during the period from and including (i) the Closing Date or (ii) such later date that such Lender becomes a party to this Agreement as provided in Section 13.06(b), to and up to, but excluding, the Revolving Credit Termination Date in an aggregate principal amount at any one time outstanding up to, but not exceeding, the amount of such Lender's US Tranche

Commitment as then in effect, minus the sum of (A) the aggregate outstanding principal amount of Equipment Loans made by such Lender, (B) the Canadian Tranche Credit Exposure of such Lender and (C) the LC Exposure of such Lender; provided, however, that the aggregate principal amount of all such Working Capital Loans by all US Tranche Lenders hereunder at any one time outstanding together with the LC Exposure shall not exceed the Working Capital Borrowing Base as then in effect. Subject to the terms of this Agreement, during the period from the Closing Date to and up to, but excluding, the Revolving Credit Termination Date, the US Borrower may borrow, repay and reborrow the amount described in this Section 2.01(a)(i).

(v) Overadvances. Notwithstanding anything contained in this Section 2.01 to the contrary, but provided the US Borrower is otherwise entitled to a Working Capital Loan under the Working Capital Borrowing Base, the US Borrower shall be entitled to request an advance in excess of the amount available under the Working Capital Borrowing Base up to the Aggregate Commitments; provided, however, (i) the US Borrower shall represent to the US Administrative Agent in the borrowing request (referenced in Section 2.02(c)) for such overadvance that such Borrower owns sufficient unencumbered equipment assets to pledge as Eligible Equipment to eliminate the overadvance and (ii) in all such cases in which the

The US Tranche Lenders shall participate in such Letters of Credit according to their respective (A) US Tranche One Percentages for Letters of Credit issued when the US Tranche Credit Exposure is less than or equal to $65,000,000 and (B) US Tranche Two Percentages for Letters of Credit issued when the US Tranche Credit Exposure is greater than $65,000,000.

The aggregate Dollar Equivalent of all Offshore Currency Letters of Credit, as of the issuance date of any such Offshore Currency Letter of Credit, shall not exceed $25,000,000 as determined by the US Administrative Agent. No Issuing Bank shall be obligated to issue an Offshore Currency Letter of Credit if such Issuing Bank has determined, in its sole discretion, that it is unable to fund obligations in the requested Offshore Currency; provided, however, the US Administrative Agent shall use its best efforts to locate suitable issuers if no Issuing Banks are able to fund obligations in the requested Offshore Currency. From and after the Closing Date, the Existing Letters of Credit shall be deemed to be Letters of Credit issued pursuant to this Section 2.01(b).

(iv) if the Issuing Bank makes any disbursement in connection with a Letter of Credit after the Revolving Credit Termination Date, such disbursement shall be an advance on behalf of the US Borrower under this Agreement and shall be reimbursed to the Issuing Bank either (A) by the US Administrative Agent applying amounts in the cash collateral account referred to in clause (iii) above until reimbursed in full, or (B) by the US Borrower pursuant to Section 2.10 (except that the US Borrower shall not have the right to request that the US Tranche Lenders make and the US Tranche Lenders shall not have any obligation to make, a Loan under this Agreement after the Revolving Credit Termination Date to fund any such disbursement); and

(v) subject to the provisions of Section 9.16 of the Guarantee and Collateral Agreement dated as of February 9, 2001 among the US Borrower, Holdings, certain subsidiaries and the US Administrative Agent, as amended, modified or restated from time to time, including that certain First Amendment to Guarantee and Collateral Agreement dated October 25, 2004, all such disbursements referred to in clause (iv) of this paragraph shall be secured only by the cash collateral referred to in clause (iii) of this paragraph and the US Borrower herby grants, and by each deposit of such cash collateral with the US Administrative Agent grants, to the US Administrative Agent a first-priority security interest in all such cash collateral, without any further action on the part of the Issuing Bank, the US Borrower, the US Administrative Agent, any US Tranche Lender or any other Person now or hereafter party hereto (other than any action the US Administrative Agent reasonably deems necessary to perfect such security interest, which action the US Borrower hereby authorizes the US Administrative Agent to take), until same are reimbursed in full.

If, on the Revolving Credit Termination Date (A) the US Tranche Commitments have been terminated, (B) the Loans, all interest thereon and all other amounts payable by the US Borrower hereunder or in connection herewith (other than the LC Exposure in connection with any Letter of Credit having an expiration date extending beyond the Revolving Credit Termination Date as permitted by Section 2.01(b)) have been paid in full, and (C) the conditions set forth in clause (iii) above have been fully satisfied, then from and after such date the following provisions of this Agreement shall not be operative: Sections 9.01 (other than Sections 9.01(a) and (b), which shall remain operative), 9.02 (except as the same may affect a Letter of Credit), 9.03(b), 9.04, 9.09, 9.10, 10.01, 10.02 (except for cash collateral securing Letters of Credit), 10.03, 10.04, 10.06, 10.08, 10.10, 10.11, 10.13, 10.14, 10.15, 10.16, 10.17 and 10.18.

If, after payment in full of all Indebtedness of the US Borrower hereunder (including without limitation, reimbursement obligations with respect to Letters of Credit) and the expiration or cancellation of all outstanding Letters of Credit, there remains any amount on deposit in the cash collateral account referred to in clause (iii) above, the US Administrative Agent shall, within three Business Days after all such Indebtedness is paid in full and all outstanding Letters of Credit have expired or been cancelled, return such amount to the US Borrower.

(i) The US Borrower agrees to pay to the US Administrative Agent, for the account of each US Tranche Lender and the Issuing Bank, commissions for issuing the Letters of Credit on the daily outstanding amount of the maximum liability of the Issuing Bank existing from time under such Letter of Credit (including the Dollar Equivalent of the face amount of the outstanding Offshore Currency Letter of Credit) (calculated separately for each Letter of Credit) at a rate equal to the Applicable Margin for LIBOR Loans, in effect from time to time during the term of each Letter of Credit, provided that each Letter of Credit shall bear a minimum yearly commission of $300.00. Each Letter of Credit shall be deemed outstanding up to the available face amount of the Letter of Credit (including the Dollar Equivalent of the face amount of the outstanding Offshore Currency Letter of Credit) until the Issuing Bank has received from the Beneficiary a written cancellation authorization, in form and substance acceptable to the Issuing Bank or until the date the Letter of Credit expires by its terms. Such commissions are payable quarterly in arrears on each Quarterly Date and upon cancellation or expiration of each such Letter of Credit.

(ii) Out of the fees described in Section 2.04(b)(i), the US Administrative Agent shall pay to the Issuing Bank, for such Issuing Bank's account, 0.125% per annum of each such fee as

an issuing fee and shall pay to the US Tranche Lenders a pro rata share of the remaining portion of such fees.

(iii) The US Borrower shall pay to the Issuing Bank for its own account, upon each drawing or payment under, issuance of, or amendment to, any Letter of Credit, such amount as shall at the time of such event be the administrative charge and reasonable outof-pocket expenses which the Issuing Bank or its Affiliate is generally imposing in connection with such occurrence with respect to letters of credit.

(c) Other Fees. The US Borrower shall pay to the US Administrative Agent for its own account such other fees as are set forth in the Fee Letter on the dates specified therein to the extent not paid prior to the Closing Date.

Section 2.05 Several Obligations. The failure of any Lender to make any Loan to be made by it or to provide funds for disbursements or reimbursements under Letters of Credit on the date specified therefor shall not relieve any other Lender of its obligation to make its Loan or provide funds on such date, but no Lender shall be responsible for the failure of any other Lender to make a Loan to be made by such other Lender or to provide funds to be provided by such other Lender.

Section 2.06 Notes.

The date, amount, Type, interest rate and Interest Period of each Loan made by each Lender, and all payments made on account of the principal thereof, shall be recorded by such Lender on its books for its applicable Note, and, prior to any transfer may be endorsed by such Lender on the schedule attached to such Note or any continuation thereof or on any separate record maintained by such Lender. Failure to make any such notation or to attach a schedule shall not affect any Lender's or any Borrower's rights or obligations in respect of such Loans or affect the validity of such transfer by any Lender of its Note.

Section 2.07 Prepayments.

(a) Voluntary Prepayments. Each Borrower may prepay the US Base Rate Loans or Canadian Prime Rate Loans, as applicable, upon not less than one (1) Business Day's prior notice to the US Administrative Agent (which shall promptly notify the Lenders including the Canadian Administrative Agent), which notice shall specify the prepayment date (which shall be a Business Day) and the amount of the prepayment (which shall be at least $1,000,000 or the remaining aggregate principal balance outstanding on the applicable Notes) and shall be irrevocable and effective only upon receipt by the US Administrative Agent, provided that interest on the principal prepaid, accrued to the prepayment date, shall be paid on the prepayment date. Each Borrower may prepay LIBOR Loans on the same conditions as for US Base Rate Loans and Canadian Prime Rate Loans (except that prior notice to the US Administrative Agent shall not be less than three (3) Business Days for LIBOR Loans) and in addition such prepayments of LIBOR Loans shall be subject to the terms of Section 5.05 and shall be in an amount equal to all of the LIBOR Loans for the Interest Period prepaid.

(b) Mandatory Prepayments.

(i) If, after giving effect to any termination or reduction of the Aggregate Commitments pursuant to Section 2.03(b), the outstanding aggregate principal amount of the Combined Credit Exposure exceeds the Aggregate Commitments, (A) the US Borrower shall prepay the US Tranche Loans on the date of such termination or reduction in an aggregate principal amount equal to the excess, together with interest on the principal amount paid accrued to

the date of such prepayment and/or (B) the Canadian Borrower shall prepay the Canadian Tranche Loans on the date of such termination or reduction in an aggregate principal amount equal to the excess, together with interest on the principal amount paid accrued to the date of such prepayment, and (C) if any excess remains after prepaying all of the US Tranche Loans and Canadian Tranche Loans because of the LC Exposure, the US Borrower shall pay to the US Administrative Agent on behalf of the US Tranche Lenders an amount equal to the excess to be held as cash collateral as provided in Section 2.10(b) hereof.

(ii) If, after giving effect to any termination or reduction of the Aggregate Canadian Tranche Commitments pursuant to Section 2.03(c), the outstanding aggregate principal amount of the Canadian Tranche Credit Exposure exceeds the Aggregate Canadian Tranche Commitments, the Canadian Borrower shall prepay the Canadian Tranche Loans on the date of such termination or reduction in an aggregate principal amount equal to the excess, together with interest on the principal amount paid accrued to the date of such prepayment.

(iii) Upon any redetermination of the amount of the Borrowing Base in accordance with Section 2.08, if the redetermined Working Capital Borrowing Base is less than the aggregate outstanding principal amount of the sum of the Canadian Tranche Credit Exposure, the Working Capital Loans and the LC Exposure then the Applicable Borrower shall, with respect to any such deficiency that is (A) equal to or less than $10,000,000, within fifteen (15) days, or (B) greater than $10,000,000, within five (5) Business Days, either (1) prepay the Canadian Tranche Credit Exposure and the Working Capital Loans in an aggregate principal amount equal to such deficiency, together with interest on the principal amount paid accrued to the date of such prepayment or (2) grant or cause to be granted to the US Administrative Agent a first priority Lien (subject only to Excepted Liens) in gas compression equipment of the US Borrower or its Subsidiaries having a fair market value (as determined by Schedule 1.01) equal to or greater than the amount of such Working Capital Borrowing Base deficiency, which pledge of Eligible Equipment shall (x) increase the amount of the Equipment Borrowing Base by and amount equal to the fair market value (as determined by Schedule 1.01) of such Eligible Equipment and (y) automatically convert Working Capital Loans in an aggregate amount equal to such fair market value of Equipment Loans; provided that if there remains a Working Capital Borrowing Base deficiency after prepaying the Canadian Tranche Credit Exposure and the Working Capital Loans or converting such Working Capital Loans to Equipment Loans by pledging gas compression equipment because the LC Exposure continues to exceed the Working Capital Borrowing Base, then the US Borrower shall pay to the US Administrative Agent on behalf of the US Tranche Lenders an amount equal to such remaining Working Capital Borrowing Base deficiency to be held as cash collateral for the Letters of Credit as provided in Section 2.10(b).

(iv) Upon any redetermination of the amount of the Borrowing Base in accordance with Section 2.08, if the redetermined Equipment Borrowing Base is less than the aggregate outstanding principal amount of the Equipment Loans then the US Borrower shall either (A) prepay the Equipment Loans in an aggregate principal amount equal to such deficiency, together with interest on the principal amount paid accrued to the date of such prepayment or (B) give written notice to the US Administrative Agent to convert Equipment Loans equal to the aggregate principal amount of such deficiency to Working Capital Loans, but only to the extent there is unused availability under the Working Capital Borrowing Base.

(v) Upon any release of Eligible Equipment pursuant to Section 9.09(b), the US Borrower shall simultaneously prepay the Equipment Loans in an aggregate principal amount equal to the fair market value of such Eligible Equipment at the time the applicable Lien was created, together with interest on the principal amount paid accrued to the date of prepayment.

(vi) Upon any overadvance pursuant to Section 2.01(a)(iv), the US Borrower shall prepay the Working Capital Loans (or pledge assets) as required by said Section 2.01(a)(iv).

(vii) Upon any disposition pursuant to Section 10.14(c), the US Borrower shall prepay Equipment Loans as provided in such section.

(c) Generally. Prepayments permitted or required under this Section 2.07 shall be without premium or penalty, except as required under Section 5.05 for prepayment of LIBOR Loans. Any prepayments on the Loans may be reborrowed subject to the then effective Aggregate Commitments and the Aggregate Canadian Tranche Commitments, as applicable.

Section 2.08 Borrowing Base.

(a) The Borrowing Base shall be determined in accordance with Section 2.08(b) and (c) by the US Administrative Agent. Upon any redetermination of the Borrowing Base, such redetermination shall remain in effect until the next successive Redetermination Date. "Redetermination Date" shall mean the date that the redetermined Borrowing Base becomes effective subject to the notice requirements specified in Section 2.08(c). So long as any of the Aggregate Commitments are in effect or any LC Exposure or Loans are outstanding hereunder, this facility shall be governed by the then effective Borrowing Base. Until the first redetermination of the Borrowing Base, the Working Capital Borrowing Base shall be $85,242,000.00 and the Equipment Borrowing Base shall be $0.00.

(b) The Borrowing Base will be redetermined 45 days following the end of each fiscal quarter of the US Borrower, commencing with the fiscal quarter ending March 31, 2005. In addition, the US Borrower shall have the right to require the US Administrative Agent to redetermine the Borrowing Base, but no more frequently than once each calendar month.

(c) Based upon the information contained in the Borrowing Base Certificate delivered pursuant to Section 9.01(i) and such other supplemental information as the US Administrative Agent may reasonably request, the US Administrative Agent will redetermine the Borrowing Base, such redetermination to be in accordance with the US Administrative Agent's normal and customary procedures as such exist at that particular time.

(d) The US Administrative Agent shall promptly notify the Borrowers and the Lenders (including the Canadian Administrative Agent) of the new Borrowing Base. Any redetermination of the Borrowing Base shall not be in effect until written notice is received by the Borrowers.

Section 2.09 Assumption of Risks. The US Borrower assumes all risks of the acts or omissions of any beneficiary of any Letter of Credit or any transferee thereof with respect to its use of such Letter of Credit. Neither the Issuing Bank (except in the case of gross negligence or willful misconduct on the part of the Issuing Bank or any of its employees as determined by final and non appealable judgment of a court of competent jurisdiction), its correspondents nor any Lender shall be responsible for the validity, sufficiency or genuineness of certificates or other documents or any endorsements thereon, even if such certificates or other documents should in fact prove to be invalid, insufficient, fraudulent or forged; for errors, omissions, interruptions or delays in transmissions or delivery of any messages by mail, telex, or otherwise, whether or not they be in code; for errors in translation or for errors in interpretation of technical terms; the validity or sufficiency of any instrument transferring or assigning or purporting to transfer or assign any Letter of Credit or the rights or benefits thereunder or proceeds thereof, in whole or in part, which may prove to be invalid or ineffective for any reason; the failure of any beneficiary or any transferee of any Letter of Credit to comply fully with conditions required in order to draw upon any Letter of Credit; or for any other consequences arising from causes beyond the Issuing Bank's control or the control of the Issuing Bank's correspondents. In addition, neither the Issuing Bank, the US Administrative Agent nor any Lender shall be responsible for any error, neglect, or default of any of the Issuing Bank's correspondents; and none of the above shall affect, impair or

prevent the vesting of any of the Issuing Bank's, the US Administrative Agent's or any Lender's rights or powers hereunder, all of which rights shall be cumulative. The Issuing Bank and its correspondents may accept certificates or other documents that appear on their face to be in order, without responsibility for further investigation of any matter contained therein regardless of any notice or information to the contrary. In furtherance and not in limitation of the foregoing provisions, the US Borrower agrees that any action, inaction or omission taken or not taken by the Issuing Bank or by any correspondent for the Issuing Bank in good faith in connection with any Letter of Credit, or any related drafts, certificates, documents or instruments, shall be binding on such Borrower and shall not put the Issuing Bank or its correspondents under any resulting liability to such Borrower.

Section 2.10 Obligation to Reimburse and to Prepay.

(a) In connection with any Letter of Credit, the US Borrower may make funds available for disbursement by the Issuing Bank in connection with such Letter of Credit. In such cases, the Issuing Bank shall use such funds which the US Borrower has made available to fund such Credit. In addition, the US Borrower may give written instructions to the Issuing Bank and the US Administrative Agent to make a Loan under this Agreement to fund any Letters of Credit which may be drawn. In all such cases, the US Borrower shall give the appropriate notices required under this Agreement for a US Base Rate Loan or a LIBOR Loan. If a disbursement by the Issuing Bank is made under any Letter of Credit, in cases in which the US Borrower has not either provided its own funds to fund a draw on a Letter of Credit or given the US Administrative Agent prior notice for a Loan under this Agreement, then the US Borrower shall pay to the US Administrative Agent within two (2) Business Days after notice of any such disbursement is received by the US Borrower, the amount of each such disbursement made by the Issuing Bank under the Letter of Credit (if such payment is not sooner effected as may be required under this Section 2.10 or under other provisions of the Letter of Credit), together with interest on the amount disbursed from and including the date of disbursement until payment in full of such disbursed amount at a varying rate per annum equal to (i) the then applicable interest rate for Base Rate Loans through the second Business Day after notice of such disbursement is received by the US Borrower and (ii) thereafter, the Post-Default Rate for Base Rate Loans (but in no event to exceed the Highest Lawful Rate) for the period from and including the third Business Day following the date of such disbursement to and including the date of repayment in full of such disbursed amount. The obligations of the US Borrower under this Agreement with respect to each Letter of Credit shall be absolute, unconditional and irrevocable and shall be paid or performed strictly in accordance with the terms of this Agreement under all circumstances whatsoever, including, without limitation, but only to the fullest extent permitted by applicable law, the following circumstances: (i) any lack of validity or enforceability of this Agreement, any Letter of Credit or any of the Security Instruments; (ii) any amendment or waiver of (including any default), or any consent to departure from this Agreement (except to the extent permitted by any amendment or waiver), any Letter of Credit or any of the Security Instruments; (iii) the existence of any claim, set-off, defense or other rights which the US Borrower may have at any time against the beneficiary of any Letter of Credit or any transferee of any Letter of Credit (or any Persons for whom any such beneficiary or any such transferee may be acting), the Issuing Bank, the US Administrative Agent, any US Tranche Lender or any other Person, whether in connection with this Agreement, any Letter of Credit, the Security Instruments, the transactions contemplated hereby or any unrelated transaction; (iv) any statement, certificate, draft, notice or any other document presented under any Letter of Credit proves to have been forged, fraudulent, insufficient or invalid in any respect or any statement therein proves to have been untrue or inaccurate in any respect whatsoever; (v) payment by the Issuing Bank under any Letter of Credit against presentation of a draft or certificate which appears on its face to comply, but does not comply, with the terms of such Letter of Credit; and (vi) any other circumstance or happening whatsoever, whether or not similar to any of the foregoing.

Notwithstanding anything in this Agreement to the contrary, the US Borrower will not be liable for payment or performance that results from the gross negligence or willful misconduct of the Issuing Bank as determined by a final and non appealable judgment of a court of competent jurisdiction, except (i) where the US Borrower or any Subsidiary actually recovers the proceeds for itself or the Issuing Bank of any payment made by the Issuing Bank in connection with such gross negligence or willful misconduct or (ii) in cases where the US Administrative Agent makes payment to the named beneficiary of a Letter of Credit.

(b) In the event of the occurrence of any Event of Default, a payment or prepayment pursuant to Section 2.07(b) or the maturity of the Notes, whether by acceleration or otherwise, an amount equal to the LC Exposure (or an amount equal to the amount by which the LC Exposure exceeds the Working Capital Borrowing Base in the case of Section 2.07(b)) shall be deemed to be forthwith due and owing by the US Borrower to the Issuing Bank, the US Administrative Agent and the US Tranche Lenders as of the date of any such occurrence; and the US Borrower's obligation to pay such amount shall be absolute and unconditional, without regard to whether any beneficiary of any such Letter of Credit has attempted to draw down all or a portion of such amount under the terms of a Letter of Credit, and, to the fullest extent permitted by applicable law, shall not be subject to any defense or be affected by a right of set-off, counterclaim or recoupment which the US Borrower may now or hereafter have against any such beneficiary, the Issuing Bank, the US Administrative Agent, the US Tranche Lenders or any other Person for any reason whatsoever. Such payments shall be held by the Issuing Bank on behalf of the US Tranche Lenders as cash collateral securing the LC Exposure in an account or accounts at the Principal Office; and the US Borrower hereby grants to and by its deposit with the US Administrative Agent grants to the US Administrative Agent a security interest in such cash collateral. In the event of any such payment by the US Borrower of amounts contingently owing under outstanding Letters of Credit and in the event that thereafter drafts or other demands for payment complying with the terms of such Letters of Credit are not made prior to the respective expiration dates thereof, the US Administrative Agent agrees, if no Event of Default has occurred and is continuing or if no other amounts are outstanding under this Agreement, the Notes or the Security Instruments, to remit to the US Borrower (i) amounts for which the contingent obligations evidenced by the Letters of Credit have ceased and (ii) amounts on deposit as cash collateral for Letters of Credit, to the extent that the LC Exposure no longer exceeds the Working Capital Borrowing Base, in connection with a redetermination of such Working Capital Borrowing Base.

(c) Each Lender severally and unconditionally agrees that it shall promptly reimburse the Issuing Bank an amount equal to such Lender's participation in any Letter of Credit as provided in Section 2.01(b) of any disbursement made by the Issuing Bank under any Letter of Credit that is not reimbursed according to this Section 2.10.

(d) Notwithstanding anything to the contrary contained herein, if no Event of Default has occurred and is continuing and subject to availability under the Aggregate Commitments (after reduction for the LC Exposure), to the extent the US Borrower has not reimbursed the Issuing Bank for any drawn upon Letter of Credit within one (1) Business Days after notice of such disbursement has been received by the US Borrower, the amount of such Letter of Credit reimbursement obligation shall automatically be funded by the US Tranche Lenders as a Loan hereunder and used by such Lenders to pay such Letter of Credit reimbursement obligation in the percentages referenced in clause (c) above. If an Event of Default has occurred and is continuing, or if the funding of such Letter of Credit reimbursement obligation as a Loan would cause the aggregate amount of all Loans outstanding to exceed the Aggregate Commitments (after reduction for the LC Exposure), such Letter of Credit reimbursement obligation shall not be funded as a Loan, but instead shall accrue interest as provided in Section 2.10(a).

Section 2.11 Lending Offices. The Loans of each Type made by each Lender shall be made and maintained at such Lender's Applicable Lending Office for Loans of such Type.

ARTICLE III
Payments of Principal and Interest

Section 3.01 Repayment of Loans. On the Revolving Credit Termination Date each Borrower shall pay to the Applicable Administrative Agent, for the account of each Applicable Lender, the outstanding aggregate principal and accrued and unpaid interest under the Loans.

Section 3.02 Interest.

(a) Interest Rates. Each Borrower will pay to the Applicable Administrative Agent, for the account of each Applicable Lender, interest on the unpaid principal amount of each Loan made by such Lender for the period commencing on the date such Loan is made to, but excluding, the date such Loan shall be paid in full, at the following rates per annum:

(i) if such a Loan is a US Base Rate Loan, the US Base Rate (as in effect from time to time) plus the Applicable Margin, but in no event to exceed the Highest Lawful Rate;

(ii) if such a Loan is a Canadian Prime Rate Loan, the Canadian Prime Rate (as in effect from time to time) plus the Applicable Margin, but in no event to exceed the Highest Lawful Rate; and

(iii) if such a Loan is a LIBOR Loan, for each Interest Period relating thereto, the LIBOR Rate for such Loan plus the Applicable Margin (as in effect from time to time), but in no event to exceed the Highest Lawful Rate.

(b) Canadian Interest.

(i) For purposes of disclosure under the Interest Act (Canada), where interest is calculated pursuant Section 3.02(a)(ii) and (iii) at a rate based upon a 360, 365 or 366 day year, as the case may be, (the "First Rate"), it is hereby agreed that the rate or percentage of interest on a yearly basis is equivalent to such First Rate multiplied by the actual number of days in the year divided by 360, 365 or 366, as applicable.

(ii) Notwithstanding the provisions of this Section 3.02 or any other provision of this Agreement, in no event shall the aggregate "interest" (as that term is defined in Section 347 of the Criminal Code (Canada)) exceed the effective annual rate of interest on the "credit advanced" (as defined therein) lawfully permitted under Section 347 of the Criminal Code (Canada). The effective annual rate of interest shall be determined in accordance with generally accepted actuarial practices and principles over the term of the applicable Canadian Tranche Loan, and in the event of a dispute, a certificate of a Fellow of the Canadian Institute of Actuaries qualified for a period of ten (10) years appointed by the Canadian Administrative Agent will be conclusive for the purposes of such determination.

(iii) A certificate of an authorized signing officer of the US Administrative Agent as to each amount and/or each rate of interest payable hereunder from time to time shall be conclusive evidence of such amount and of such rate, absent manifest error.

(iv) Wherever in this Agreement reference is made to a rate of interest "per annum" or a similar expression is used, such interest shall be calculated using the nominal rate method of calculation and shall not be calculated using the effective rate method of calculation or any other basis that gives effect to the principle of deemed reinvestment of interest.

(c) Post-Default Rate. Notwithstanding the foregoing, each Borrower will pay to the Applicable Administrative Agent, for the account of each Applicable Lender interest at the applicable Post-Default Rate on any principal of any Loan made by such Lender, and (to the fullest extent permitted by law) on any other amount payable by each Borrower hereunder, under any Loan Document or under any Note held by such Lender to or for account of such Lender, for

the period commencing on the date of an Event of Default until the same is paid in full or all Events of Default are cured or waived.

(d) Due Dates. Accrued interest on US Base Rate Loans and Canadian Prime Rate Loans shall be payable on each Quarterly Date commencing on December 31, 2004, and accrued interest on each LIBOR Loan shall be payable on the last day of the Interest Period therefor and, if such Interest Period is longer than three months at three-month intervals following the first day of such Interest Period, except that interest payable at the Post-Default Rate shall be payable from time to time on demand and interest on any LIBOR Loan that is converted into a US Base Rate Loan or a Canadian Prime Rate Loan, as applicable (pursuant to Section 5.04) shall be payable on the date of conversion (but only to the extent so converted). Any accrued and unpaid interest on the Loans shall be paid on the Revolving Credit Termination Date.

(e) Determination of Rates. Promptly after the determination of any interest rate provided for herein or any change therein, the US Administrative Agent shall notify the Lenders (including the Canadian Administrative Agent) to which such interest is payable and the Applicable Borrower thereof. Each determination by the US Administrative Agent of an interest rate or fee hereunder shall, except in cases of manifest error, be final, conclusive and binding on the parties.

ARTICLE IV
Payments; Pro Rata Treatment; Computations; Etc.

Section 4.01 Payments. Except to the extent otherwise provided herein, all payments of principal, interest and other amounts to be made by each Borrower under this Agreement and the Notes shall be made in Dollars in the case of US Tranche Loans, and in Canadian Dollars in the case of Canadian Tranche Loans, in immediately available funds, to the Applicable Administrative Agent at such account as such Administrative Agent shall specify by notice to the Applicable Borrower from time to time, not later than 11:00 a.m. Eastern time on the date on which such payments shall become due (each such payment made after such time on such due date to be deemed to have been made on the next succeeding Business Day). Such payments shall be made without (to the fullest extent permitted by applicable law) defense, setoff or counterclaim. Each such payment so received by the Applicable Administrative Agent under this Agreement or any Note for account of a Lender shall be paid promptly to such Lender in immediately available funds. Except as otherwise provided in the definition of "Interest Period", if the due date of any payment under this Agreement or any Note would otherwise fall on a day which is not a Business Day such date shall be extended to the next succeeding Business Day and interest shall be payable for any principal so extended for the period of such extension. At the time of each payment to the Applicable Administrative Agent of any principal of or interest on any Borrowing, the Applicable Borrower shall notify the Applicable Administrative Agent of the Loans to which such payment shall apply. In the absence of such notice the Administrative Agents may specify the Loans to which such payment shall apply, but to the extent possible such payment or prepayment will be applied first to the Loans comprised of US Base Rate Loans or Canadian Prime Rate Loans.

Section 4.02 Pro Rata Treatment. Except to the extent otherwise provided herein each Lender agrees that: (i) each Borrowing from the Lenders under Section 2.01 and each continuation and conversion under Section 2.02 shall be made from the Applicable Lenders pro rata in accordance with their US Tranche One Percentages, US Tranche Two Percentages or Canadian Tranche Percentages as the case may be, each payment of fees under Section 2.04 shall be made for account of the Applicable Lenders pro rata in accordance with such same percentages, and each termination or reduction of the amount of the Aggregate Commitments under Section 2.03(b) or the Aggregate Canadian Tranche Commitments under Section 2.03(c) shall be applied to the US Tranche Commitment or Canadian Tranche Commitment, as applicable of each Applicable Lender, pro rata according to the amounts of its respective US Tranche Commitment or Canadian Tranche Commitment, as applicable; provided that

reductions of the US Tranche Commitments when the Aggregate Commitments are greater than $65,000,000 shall be applied pro rata according to the US Tranche Two Percentages and reductions of the US Tranche Commitments when the Aggregate Commitments are equal to or less than $65,000,000 shall be applied pro rata according to the US Tranche One Percentages; (ii) each payment of commitments fees under Section 2.04(a) shall be made to each US Tranche Lender in accordance with such section; (iii) each payment of principal of Loans by each Borrower shall be made for account of the Applicable Lenders pro rata in accordance with the respective unpaid principal amount of the Loans held by the Applicable Lenders; (iv) each payment of interest on Loans by each Borrower shall be made for account of the Applicable Lenders pro rata in accordance with the amounts of interest due and payable to the respective Lenders; and (v) each reimbursement by the US Borrower of disbursements under Letters of Credit shall be made for account of the Issuing Bank or, if funded by the US Tranche Lenders, pro rata for the account of the US Tranche Lenders, in accordance with the amounts of reimbursement obligations due and payable to each respective US Tranche Lender; provided that if no Event of Default has occurred and is continuing, the reimbursement of the US Tranche Lenders for disbursements made under Letters of Credit and the repayment of US Tranche Loans (A) when the US Tranche Credit Exposure is less than or equal to $65,000,000 shall be applied pro rata in accordance with the US Tranche One Percentages and (B) when the US Tranche Credit Exposure is greater than $65,000,000 shall be applied pro rata in accordance with the US Tranche Two Percentages.

Section 4.03 Computations. Interest on LIBOR Loans and fees shall be computed on the basis of a year of 360 days and actual days elapsed (including the first day but excluding the last day) occurring in the period for which such interest is payable, unless such calculation would exceed the Highest Lawful Rate, in which case interest shall be calculated on the per annum basis of a year of 365 or 366 days, as the case may be. Interest on US Base Rate Loans and Canadian Prime Rate Loans shall be computed on the basis of a year of 365 or 366 days, as the case may be, and actual days elapsed (including the first day but excluding the last day) occurring in the period for which such interest is payable.

Section 4.04 Agent Reliance. Unless the US Administrative Agent shall have received notice from a Lender before the date of any Borrowing of the proceeds of the Loan that such Lender will not make available to the Applicable Administrative Agent such Lender's Percentage Share of such advance, such Administrative Agent may assume that such Lender has made its Percentage Share of such Borrowing available to such Administrative Agent on the date of such Borrowing in accordance with Section 2.02(c) and such Administrative Agent may, in reliance upon such assumption, make available to the Applicable Borrower on such date a corresponding amount. If and to the extent that such Lender shall not have so made its Percentage Share of such Borrowing available to such Administrative Agent, such Lender agrees to immediately pay to such Administrative Agent on demand such corresponding amount, together with interest on such amount, for each day from the date such amount is made available to the Applicable Borrower until the date such amount is paid to the Applicable Administrative Agent, at the overnight Federal Funds Rate. If such Lender shall pay to the Applicable Administrative Agent such corresponding amount and interest as provided above, such corresponding amount so paid shall constitute such Lender's advance as part of such Borrowing for purposes of this Agreement even though not made on the same day as the other advances comprising such Borrowing.

Section 4.05 Set-off, Sharing of Payments, Etc.

(a) Each Borrower agrees that, in addition to (and without limitation of) any right of set-off, bankers' lien or counterclaim a Lender may otherwise have, each Lender shall have the right and be entitled (after consultation with the US Administrative Agent), at its option, to offset balances held by it or by any of its Affiliates for account of the Applicable Borrower at any of its offices, in Dollars or in any other currency, against any principal of or interest on any of such Lender's

Loans, or any other amount payable to such Lender hereunder, which is not paid when due (including applicable grace periods) (regardless of whether such balances are then due to such Borrower), in which case it shall promptly notify the Applicable Borrower and the US Administrative Agent thereof, provided that such Lender's failure to give such notice shall not affect the validity thereof.

(b) If any Lender shall obtain payment of any principal of or interest on any Loan made by it to a Borrower under this Agreement (or reimbursement as to any Letter of Credit) through the exercise of any right of set-off, banker's lien or counterclaim or similar right or otherwise, and, as a result of such payment, such Lender shall have received a greater percentage of the principal or interest (or reimbursement) then due hereunder by the Applicable Borrower to such Lender than the percentage received by any other Applicable Lenders, it shall promptly (i) notify the US Administrative Agent and each other Lender (including the Canadian Administrative Agent) thereof and (ii) purchase from such other Applicable Lenders participations in (or, if and to the extent specified by such Applicable Lender, direct interests in) the Loans (or participations in Letters of Credit) made by such other Applicable Lenders (or in interest due thereon, as the case may be) in such amounts, and make such other adjustments from time to time as shall be equitable, to the end that all the Applicable Lenders shall share the benefit of such excess payment (net of any expenses which may be incurred by such Lender in obtaining or preserving such excess payment) pro rata in accordance with the unpaid principal and/or interest on the Loans held by each of the Applicable Lenders (or reimbursements of Letters of Credit). To such end all the Applicable Lenders shall make appropriate adjustments among themselves (by the resale of participations sold or otherwise) if such payment is rescinded or must otherwise be restored. Each Borrower agrees that any Lender so purchasing a participation (or direct interest) in the Loans made by other Lenders (or in interest due thereon, as the case may be) may exercise all rights of set-off, banker's lien, counterclaim or similar rights with respect to such participation as fully as if such Lender were a direct holder of Loans (or Letters of Credit) in the amount of such participation. Nothing contained herein shall require any Lender to exercise any such right or shall affect the right of any Lender to exercise, and retain the benefits of exercising, any such right with respect to any other indebtedness or obligation of each Borrower. If under any applicable bankruptcy, insolvency or other similar law, any Lender receives a secured claim in lieu of a set-off to which this Section 4.05 applies, such Lender shall, to the extent practicable, exercise its rights in respect of such secured claim in a manner consistent with the rights of the Applicable Lenders entitled under this Section 4.05 to share the benefits of any recovery on such secured claim.

(c) Notwithstanding anything to the contrary contained in this Agreement, the Lenders hereby agree that they shall not set off any funds in any lock boxes whatsoever in connection with this Agreement, except for such lock boxes which may be established in connection with this Agreement.

Section 4.06 Taxes.

(a) Payments Free and Clear. Any and all payments by each Borrower hereunder shall be made, in accordance with Section 4.01, free and clear of and without deduction for any and all present or future taxes, levies, imposts, deductions, charges or withholdings, and all liabilities with respect thereto, excluding, in the case of each Lender, the Issuing Bank, the US Administrative Agent and the Canadian Administrative Agent (each a "Recipient"), taxes imposed on its income, and franchise or similar taxes imposed on it, by (i) any jurisdiction (or political subdivision thereof) of which such Recipient is a citizen or resident or in which such Lender has an Applicable Lending Office, (ii) the jurisdiction (or any political subdivision thereof) in which such Recipient is organized, or (iii) any jurisdiction (or political subdivision thereof) in which such Recipient is presently doing business which taxes are imposed solely as a result of doing business in such jurisdiction (all such non-excluded taxes, levies, imposts, deductions, charges, withholdings and

liabilities being hereinafter referred to as "Taxes"). If any Borrower shall be required by law to deduct any Taxes from or in respect of any sum payable hereunder to a Recipient, (i) the sum payable shall be increased by the amount necessary so that after making all required deductions (including deductions applicable to additional sums payable under this Section 4.06) such Recipient shall receive an amount equal to the sum it would have received had no such deductions been made, (ii) such Borrower shall make such deductions and (iii) such Borrower shall pay the full amount deducted to the relevant taxing authority or other Governmental Authority in accordance with applicable law.

(b) Other Taxes. In addition, to the fullest extent permitted by applicable law, each Borrower agrees to pay any present or future stamp or documentary taxes or any other excise or property taxes, charges or similar levies that arise from any payment made hereunder or from the execution, delivery or registration of, or otherwise with respect to, this Agreement, any Assignment or any Security Instrument (hereinafter referred to as "Other Taxes").

(c) Indemnification. To the fullest extent permitted by applicable law, each Borrower will indemnify each Lender and the Issuing Bank and the Administrative Agents for the full amount of Taxes and Other Taxes (including, but not limited to, any Taxes or Other Taxes imposed by any Governmental Authority on amounts payable under this Section 4.06)paid by such Lender, the Issuing Bank or the Administrative Agents (on their behalf or on behalf of any Lender), as the case may be, and any liability (including penalties, interest and expenses) arising therefrom or with respect thereto, whether or not such Taxes or Other Taxes were correctly or legally asserted unless the payment of such Taxes was not correctly or legally asserted and such Lender's payment of such Taxes or Other Taxes was the result of its gross negligence or willful misconduct. Any payment pursuant to such indemnification shall be made within thirty (30) days after the date any Lender, the Issuing Bank or the Administrative Agents, as the case may be, make written demand therefor. If any Lender or any Administrative Agent receives a refund or credit in respect of any Taxes or Other Taxes for which such Lender, Issuing Bank or Administrative Agent has received payment from the Applicable Borrower it shall promptly notify such Borrower of such refund or credit and shall, if no default has occurred and is continuing, within thirty (30) days after receipt of a request by such Borrower (or promptly upon receipt, if the Applicable Borrower has requested application for such refund or credit pursuant hereto), pay an amount equal to such refund or credit to the Applicable Borrower without interest (but with any interest so refunded or credited), provided that such Borrower, upon the request of such Lender, Issuing Bank or Administrative Agent, agrees to return such refund or credit (plus penalties, interest or other charges) to such Lender or Administrative Agent in the event such Lender or Administrative Agent is required to repay such refund or credit.

(d) Lender Representations.

(i) Each US Tranche Lender represents that it is either (1) a banking association or corporation organized under the laws of the United States of America or any state thereof or (2) it is entitled to complete exemption from United States withholding tax imposed on or with respect to any payments, including fees, to be made to it pursuant to this Agreement (A) under an applicable provision of a tax convention to which the United States of America is a party or (B) because it is acting through a branch, agency or office in the United States of America and any payment to be received by it hereunder is effectively connected with a trade or business in the United States of America. Each US Tranche Lender that is not a banking association or corporation organized under the laws of the United States of America or any state thereof agrees to provide to the US Borrower and the US Administrative Agent on the Closing Date, or on the date of its delivery of the Assignment pursuant to which it becomes a US Tranche Lender, and at such other times as required by United States law or as the US Borrower or the US Administrative Agent shall reasonably request, two accurate and complete

original signed copies of either (A) Internal Revenue Service Form W-8 ECI (or successor form) certifying that all payments to be made to it hereunder will be effectively connected to a United States trade or business (the "Form W-8 ECI Certification") or (B) Internal Revenue Service Form W-8 BEN (or successor form) certifying that it is entitled to the benefit of a provision of a tax convention to which the United States of America is a party which completely exempts from United States withholding tax all payments to be made to it hereunder (the "Form W-8 BEN Certification"). In addition, each US Tranche Lender agrees that if it previously filed a Form W-8 ECI Certification or a Form W-8 BEN Certification, it will deliver to the US Borrower and the US Administrative Agent a new certification (i) within 30 days after a change in circumstances that causes any information on the Form W-8 ECI or Form W-8 BEN, as applicable, to be incorrect and (ii) prior to the first payment date falling in the third year following the previous filing of such certification. Each US Tranche Lender also agrees to deliver to the US Borrower and the US Administrative Agent such other or supplemental forms as may at any time be required as a result of changes in applicable law or regulation in order to confirm or maintain in effect its entitlement to exemption from United States withholding tax on any payments hereunder, provided that the circumstances of such US Tranche Lender at the relevant time and applicable laws permit it to do so. If a US Tranche Lender determines, as a result of any change in either (i) a Governmental Requirement or (ii) its circumstances, that it is unable to submit any form or certificate that it is obligated to submit pursuant to this Section 4.06, or that it is required to withdraw or cancel any such form or certificate previously submitted, it shall promptly notify the US Borrower and the US Administrative Agent of such fact. If a US Tranche Lender is organized under the laws of a jurisdiction outside the United States of America, unless the US Borrower and the US Administrative Agent have received a Form W-8 BEN Certification or Form W-8 ECI Certification satisfactory to them indicating that all payments to be made to such Lender hereunder are not subject to United States withholding tax, the US Borrower shall withhold taxes from such payments at the applicable statutory rate. Each US Tranche Lender agrees to indemnify and hold harmless the US Borrower or the US Administrative Agent, as applicable, from any United States taxes, penalties, interest and other expenses, costs and losses incurred or payable by (i) the US Administrative Agent as a result of such US Tranche Lender's failure to submit any form or certificate that it is required to provide pursuant to this Section 4.06 or (ii) the US Borrower or the US Administrative Agent as a result of their reliance on any such form or certificate which such US Tranche Lender has provided to them pursuant to this Section 4.06.

(ii) For any period with respect to which a US Tranche Lender has failed to provide the US Borrower with the form required pursuant to this Section 4.06, if any, (other than if such failure is due to a change in a Governmental Requirement occurring subsequent to the date on which a form originally was required to be provided), such US Tranche Lender shall not be entitled to indemnification under Section 4.06 with respect to taxes imposed by the United States which taxes would not have been imposed but for such failure to provide such forms; provided, however, that if a US Tranche Lender, which is otherwise exempt from or subject to a reduced rate of withholding tax, becomes subject to taxes because of its failure to deliver a form required hereunder, the US Borrower shall take such steps as such US Tranche Lender shall reasonably request to assist such US Tranche Lender to recover such taxes.

(iii) Any US Tranche Lender claiming any additional amounts payable pursuant to this Section 4.06 shall use reasonable efforts (consistent with legal and regulatory restrictions) to file any certificate or document requested by the US Borrower or the US Administrative Agent or to change the jurisdiction of its Applicable Lending Office or to contest any tax imposed if the making of such a filing or change or contesting such tax would avoid the need for or reduce the amount of any such additional amounts that may thereafter accrue and would not, in the sole determination of such US Tranche Lender, be otherwise disadvantageous to such US Tranche Lender.

(iv) Each Canadian Tranche Lender represents that it is (a) either not a non-resident of Canada for purposes of the Income Tax Act (Canada) or a deemed resident of Canada for purposes of Part XIII of the Income Tax Act (Canada) and (b) an Affiliate of a US Tranche Lender.

ARTICLE V
Capital Adequacy

Section 5.01 Additional Costs.

(a) LIBOR Regulations, etc. Each Borrower shall pay directly to each Applicable Lender from time to time such amounts as such Lender may determine to be necessary to compensate such Lender for any costs which it determines are attributable to its making or maintaining of any LIBOR Loans or issuing or participating in Letters of Credit hereunder or its obligation to make any LIBOR Loans or issue or participate in any Letters of Credit hereunder, or any reduction in any amount receivable by such Lender hereunder in respect of any of such LIBOR Loans, Letters of Credit or such obligation (such increases in costs and reductions in amounts receivable being herein called "Additional Costs"), resulting from any Regulatory Change which: (i) changes the basis of taxation of any amounts payable to such Lender under this Agreement or any Note in respect of any of such LIBOR Loans or Letters of Credit (other than taxes imposed on the overall net income of such Lender or of its Applicable Lending Office for any of such LIBOR Loans by the jurisdiction in which such Lender has its principal office or Applicable Lending Office); or (ii) imposes or modifies any reserve, special deposit, minimum capital, capital ratio or similar requirements relating to any extensions of credit or other assets of, or any deposits with or other liabilities of such Lender, or the US Tranche Commitment or Canadian Tranche Commitment or Loans of such Lender or the London interbank market; or (iii) imposes any other condition affecting this Agreement or any Note (or any of such extensions of credit or liabilities) or such Lender's US Tranche Commitment or Canadian Tranche Commitment or Loans. Each Lender will notify the US Administrative Agent and the Applicable Borrower of any event occurring after the Closing Date which will entitle such Lender to compensation pursuant to this Section 5.01(a) as promptly as practicable after it obtains knowledge thereof and determines to request such compensation, and will designate a different Applicable Lending Office for the Loans of such Lender affected by such event if such designation will avoid the need for, or reduce the amount of, such compensation and will not, in the sole opinion of such Lender, be disadvantageous to such Lender, provided that such Lender shall have no obligation to so designate an Applicable Lending Office located in the United States. If any Lender requests compensation from any Borrower under this Section 5.01(a), such Borrower may, by notice to such Lender, suspend the obligation of such Lender to make additional Loans of the Type with respect to which such compensation is requested until the Regulatory Change giving rise to such request ceases to be in effect (in which case the provisions of Section 5.04 shall be applicable).

(b) Regulatory Change. Without limiting the effect of the provisions of Section 5.01(a), in the event that at any time (by reason of any Regulatory Change or any other circumstances arising after the Closing Date affecting (A) any Lender, (B) the London interbank market or (C) such Lender's position in such market), the LIBOR Rate, as determined in good faith by such Lender, will not adequately and fairly reflect the cost to such Lender of funding its LIBOR Loans, then, if such Lender so elects, by notice to the Applicable Borrower and the US Administrative Agent, the obligation of such Lender to make additional LIBOR Loans shall be suspended until such Regulatory Change or other circumstances ceases to be in effect (in which case the provisions of Section 5.04 shall be applicable).

(c) Capital Adequacy. Without limiting the effect of the foregoing provisions of this Section 5.01 (but without duplication), each Borrower shall pay directly to any Applicable Lender

from time to time on request such amounts as such Lender may reasonably determine to be necessary to compensate such Lender or its parent or holding company for any costs which it determines are attributable to the maintenance by such Lender or its parent or holding company (or any Applicable Lending Office), pursuant to any Governmental Requirement following any Regulatory Change, of capital in respect of its US Tranche Commitments or Canadian Tranche Commitments, its Note, its Loans or any interest held by it in any Letter of Credit, such compensation to include, without limitation, an amount equal to any reduction of the rate of return on assets or equity of such Lender or its parent or holding company (or any Applicable Lending Office) to a level below that which such Lender or its parent or holding company (or any Applicable Lending Office) could have achieved but for such Governmental Requirement. Such Lender will notify the Applicable Borrower that it is entitled to compensation pursuant to this Section 5.01(c) as promptly as practicable after it determines to request such compensation.

(d) Compensation Procedure. Any Lender notifying the Applicable Borrower of the incurrence of additional costs under this Section 5.01 shall in such notice to such Borrower and the US Administrative Agent set forth in reasonable detail the basis and amount of its request for compensation. Determinations and allocations by each Lender for purposes of this Section 5.01 of the effect of any Regulatory Change pursuant to Section 5.01(a) or (b), or of the effect of capital maintained pursuant to Section 5.01(c), on its costs or rate of return of maintaining Loans or its obligation to make Loans or issue Letters of Credit, or on amounts receivable by it in respect of Loans or Letters of Credit, and of the amounts required to compensate such Lender under this Section 5.01, shall be conclusive and binding for all purposes, provided that such determinations and allocations are made on a reasonable basis. Any request for additional compensation under this Section 5.01 shall be paid by the Applicable Borrower within thirty (30) days of the receipt by such Borrower of the notice described in this Section 5.01(d).

Section 5.02 Limitation on LIBOR Loans. Anything herein to the contrary notwithstanding, if, on or prior to the determination of any LIBOR Rate for any Interest Period:

(a) the US Administrative Agent determines (which determination shall be conclusive, absent manifest error) that quotations of interest rates for the relevant deposits referred to in the applicable definition of "LIBOR Rate" in Section 1.02 are not being provided in the relevant amounts or for the relevant maturities for purposes of determining rates of interest for LIBOR Loans as provided herein; or

(b) the US Administrative Agent determines (which determination shall be conclusive, absent manifest error) that the relevant rates of interest referred to in the applicable definition of "LIBOR Rate" in Section 1.02upon the basis of which the rate of interest for LIBOR Loans for such Interest Period is to be determined are not sufficient to adequately cover the cost to the Lenders of making or maintaining LIBOR Loans;

(c) then the US Administrative Agent shall give the Applicable Borrower prompt notice thereof, and so long as such condition remains in effect, the Lenders shall be under no obligation to make additional LIBOR Loans.

Section 5.03 Illegality. Notwithstanding any other provision of this Agreement, in the event that it becomes unlawful for any Lender or its Applicable Lending Office to honor its obligation to make or maintain LIBOR Loans hereunder, then such Lender shall promptly notify the Applicable Borrower thereof and such Lender's obligation to make LIBOR Loans shall be suspended until such time as such Lender may again make and maintain LIBOR Loans (in which case the provisions of Section 5.04 shall be applicable).

Section 5.04 Base Rate and Prime Rate Loans Pursuant to Sections 5.01, 5.02 and 5.03. If the obligation of any Lender to make LIBOR Loans shall be suspended pursuant to Sections 5.01, 5.02 or

5.03 ("Affected Loans"), all Affected Loans which would otherwise be made by such Lender shall be made instead as either US Base Rate Loans or Canadian Prime Rate Loans, as applicable (and, if an event referred to in Section 5.01(b) or Section 5.03 has occurred and such Lender so requests by notice to the Applicable Borrower, all Affected Loans of such Lender then outstanding shall be automatically converted into US Base Rate Loans or Canadian Prime Rate Loans, as applicable on the date specified by the Lender in such notice) and, to the extent that Affected Loans are so made as (or converted into) US Base Rate Loans or Canadian Prime Rate Loans, all payments of principal which would otherwise be applied to such Lender's Affected Loans shall be applied instead to its respective US Base Rate Loans or Canadian Prime Rate Loans.

Section 5.05 Compensation. Each Borrower shall pay to each Applicable Lender within thirty (30) days of receipt of written request of such Lender (which request shall set forth, in reasonable detail, the basis for requesting such amounts and which shall be conclusive and binding for all purposes provided that such determinations are made on a reasonable basis), such amount or amounts as shall compensate it for any loss, cost, expense or liability which such Lender determines are attributable to:

(a) any payment, prepayment or conversion of a LIBOR Loan properly made by such Lender or any Borrower for any reason (including, without limitation, the acceleration of the Loans pursuant to Section 11.01) on a date other than the last day of the Interest Period for such Loan; or

(b) any failure by a Borrower for any reason (including but not limited to, the failure of any of the conditions precedent specified in ARTICLE VI to be satisfied) to borrow, continue or convert a LIBOR Loan from such Lender on the date for such Borrowing, continuation or conversion specified in the relevant notice given pursuant to Section 2.02(c).

Without limiting the effect of the preceding sentence, such compensation shall include an amount equal to the excess, if any, of (i) the amount of interest which would have accrued on the principal amount so paid, prepaid or converted or not borrowed for the period from the date of such payment, prepayment or conversion or failure to borrow to the last day of the Interest Period for such Loan (or, in the case of a failure to borrow, the Interest Period for such Loan which would have commenced on the date specified for such Borrowing) at the applicable rate of interest for such Loan provided for herein over (ii) the interest component of the amount such Lender would have bid in the London interbank market for Dollar deposits (or in the case of a Canadian Tranche Lender, Canadian Dollar deposits) of leading banks in amounts comparable to such principal amount and with maturities comparable to such period (as reasonably determined by such Lender).

Section 5.06 Replacement Lenders.

(a) If any Lender has notified the Borrowers and the US Administrative Agent of its incurring additional costs under Section 5.01 or has required the Borrowers to make payments for Taxes under Section 4.06, then the Borrowers may, unless such Lender has notified the Borrowers and the US Administrative Agent that the circumstances giving rise to such notice no longer apply, terminate, in whole but not in part, the US Tranche Commitment and Canadian Tranche Commitment, if any, of any Lender (other than the Administrative Agents) (the "Terminated Lender") at any time upon five (5) Business Days' prior written notice to the Terminated Lender and the US Administrative Agent (such notice referred to herein as a "Notice of Termination").

(b) In order to effect the termination of the US Tranche Commitment and the Canadian Tranche Commitment, if any of the Terminated Lender, the Borrowers shall: (i) obtain an agreement with one or more Lenders to increase their US Tranche Commitment or US Tranche Commitments and their Canadian Tranche Commitment or Canadian Tranche Commitments, as applicable and/or (ii) request any one or more other banking institutions to become parties to this Agreement in place and instead of such Terminated Lender and agree to accept such commitment

or commitments; provided, however, that such one or more other banking institutions are reasonably acceptable to the Administrative Agents and become parties by executing an Assignment (the Lenders or other banking institutions that agree to accept in whole or in part the US Tranche Commitment and Canadian Tranche Commitment, if any of the Terminated Lender being referred to herein as the "Replacement Lenders"), such that the aggregate increased and/or accepted commitments of the Replacement Lenders under clauses (i) and (ii) above equal the US Tranche Commitment and the Canadian Tranche Commitment, if any, of the Terminated Lender.

(c) The Notice of Termination shall include the name of the Terminated Lender, the date the termination will occur (the "Lender Termination Date"), and the Replacement Lender or Replacement Lenders to which the Terminated Lender will assign its US Tranche Commitment and Canadian Tranche Commitment, if any, and, if there will be more than one Replacement Lender, the portion of the Terminated Lender's US Tranche Commitment and Canadian Tranche Commitment, if any, to be assigned to each Replacement Lender.

(d) On the Lender Termination Date, (i) the Terminated Lender shall by execution and delivery of an Assignment assign its US Tranche Commitment and Canadian Tranche Commitment, if any, to the Replacement Lender or Replacement Lenders (pro rata, if there is more than one Replacement Lender, in proportion to the portion of the Terminated Lender's US Tranche Commitment and Canadian Tranche Commitment, if any, to be assigned to each Replacement Lender) indicated in the Notice of Termination and shall assign to the Replacement Lender or Replacement Lenders each of its Loans (if any) then outstanding and participation interests in Letters of Credit (if any) then outstanding pro rata as aforesaid), (ii) the Terminated Lender shall endorse its Note(s), payable without recourse, representation or warranty to the order of the Replacement Lender or Replacement Lenders (pro rata as aforesaid), (iii) the Replacement Lender or Replacement Lenders shall purchase the Note(s) held by the Terminated Lender (pro rata as aforesaid) at a price equal to the unpaid principal amount thereof plus interest and facility and other fees accrued and unpaid to the Lender Termination Date, and (iv) the Replacement Lender or Replacement Lenders will thereupon (pro rata as aforesaid) succeed to and be substituted in all respects for the Terminated Lender with like effect as if becoming a Lender pursuant to the terms of Section 13.06(b), and the Terminated Lender will have the rights and benefits of an assignor under Section 13.06(b). To the extent not in conflict, the terms of Section 13.06(b) shall supplement the provisions of this Section 5.06(d). For each assignment made under this Section 5.06, the Replacement Lender shall pay to the Applicable Administrative Agent the processing fee provided for in Section 13.06(b). The Borrowers will be responsible for the payment of any breakage costs incurred in connection with the sale of Loans by Terminated Lenders to Replacement Lenders, as if such Loans had been prepaid and breakage costs had accrued thereto in accordance with Section 5.05.

Section 7.04 No Breach. Neither the execution and delivery of the Loan Documents, nor compliance with the terms and provisions hereof will conflict with or result in a breach of, or require any consent which has not been obtained as of the Closing Date under, the respective charter or by-laws of the US Borrower or any Subsidiary, or any Governmental Requirement or any agreement or instrument to which the US Borrower or any Subsidiary is a party or by which it is bound or to which it or its Properties are subject, or constitute a default under any such agreement or instrument, or result in the creation or imposition of any Lien upon any of the revenues or assets of the US Borrower or any Subsidiary pursuant to the terms of any such agreement or instrument other than the Liens created by the Loan Documents.

Section 7.05 Authority. The US Borrower and each Subsidiary have all necessary power and authority to execute, deliver and perform its obligations under the Loan Documents to which it is a party; and the execution, delivery and performance by the US Borrower and each Subsidiary of the Loan Documents to which it is a party, have been duly authorized by all necessary action on its part; and the Loan Documents constitute the legal, valid and binding obligations of the US Borrower and each Subsidiary, enforceable in accordance with their terms, except to the extent that the enforceability thereof may be limited by applicable bankruptcy, insolvency, reorganization, moratorium or other similar laws generally affecting creditors' rights and by equitable principles (regardless of whether enforcement is sought in equity or at law).

Section 7.06 Approvals. No authorizations, approvals or consents of, and no filings or registrations with, any Governmental Authority are necessary for the execution, delivery or performance by the US Borrower or any Subsidiary of the Loan Documents or for the validity or enforceability thereof, except for the recording and filing of the Security Instruments as required by this Agreement.

(a) The US Borrower, each Subsidiary and each ERISA Affiliate have complied in all material respects with ERISA and, where applicable, the Code regarding each Plan.

(b) Each Plan is, and has been, maintained in substantial compliance with ERISA and, where applicable, the Code.

(d) No Plan (other than a defined contribution plan) or any trust created under any such Plan has been terminated since September 2, 1974.

(b) No Indemnified Party may settle any claim to be indemnified without the consent of the indemnitor, such consent not to be unreasonably withheld; provided, that the indemnitor may not reasonably withhold consent to any settlement that an Indemnified Party proposes, if the indemnitor does not have the financial ability to pay all its obligations outstanding and asserted against the indemnitor at that time, including the maximum potential claims against the Indemnified Party to be indemnified pursuant to this Section 13.03.

Section 13.05 Successors and Assigns. This Agreement shall be binding upon and inure to the benefit of the parties hereto and their respective successors and permitted assigns.

Section 13.06 Assignments and Participations.

(a) Neither Borrower may assign its rights or obligations hereunder or under the Notes or any Letters of Credit without the prior consent of all of the Lenders and the Administrative Agents.

(b) Any Lender may, upon the written consent of the US Administrative Agent and the US Borrower, which consent shall not be unreasonably withheld, assign to one or more assignees all or a portion of its rights and obligations under this Agreement pursuant to an Assignment Agreement substantially in the form of Exhibit E (an "Assignment"); provided, however, that (i) any such assignment shall be in the amount of at least $5,000,000 of a Tranche or such lesser amount to which such Borrower has consented; (ii) if the assignor is a Lender, individually or with its Affiliates, in both Tranches, the same pro rata interest in each Tranche will be assigned; (iii) the assignee or assignor shall pay to the Applicable Administrative Agent a processing and recordation fee of $3,500 for each assignment; provided that only $3,500 shall be paid for pro rata assignments by a Lender and its Canadian Affiliate; and (iv) such Borrower's consent shall not be required if an Event of Default has occurred and is continuing. Any such assignment will become effective upon the execution and delivery to the US Administrative Agent of the Assignment and the consent of the US Administrative Agent, which consent shall not be unreasonably withheld. Promptly after receipt of an executed Assignment, the US Administrative Agent shall send to the Applicable Borrower a copy of such executed Assignment. Upon receipt of such executed Assignment, such Borrower, will, at its own expense, execute and deliver new Notes to the assignor and/or assignee, as appropriate, in accordance with their respective interests as they appear. Upon the effectiveness of any assignment pursuant to this Section 13.06(b), the assignee will become a "Lender," if not already a "Lender," for all purposes of this Agreement and the Security Instruments. The assignor shall be relieved of its obligations hereunder to the extent of such assignment (and if the assigning Lender no longer holds any rights or obligations under this Agreement, such assigning Lender shall cease to be a "Lender" hereunder except that its rights under Sections 4.06, 5.01, 5.05 and 13.03 shall not be affected). The US Administrative Agent will prepare on the last Business Day of each month during which an assignment has become effective

pursuant to this Section 13.06(b), a new Annex I and II giving effect to all such assignments effected during such month, and will promptly provide the same to the Borrowers, the Canadian Administrative Agent and each of the Lenders.

(c) Each Lender may transfer, grant or assign participations in all or any part of such Lender's interests hereunder pursuant to this Section 13.06(c) to any Person, provided that: (i) such Lender shall remain a "Lender" for all purposes of this Agreement and the transferee of such participation shall not constitute a "Lender" hereunder; and (ii) no participant under any such participation shall have rights to approve any amendment to or waiver of any of the Loan Documents except to the extent such amendment or waiver would (x) forgive any principal owing on any Indebtedness or extend the final maturity of the Loans, (y) reduce the interest rate (other than as a result of waiving the applicability of any post-default increases in interest rates) or fees applicable to any of the US Tranche Commitments or Canadian Tranche Commitments or Loans or Letters of Credit in which such participant is participating, or postpone the payment of any thereof, or (z) release any guarantor of the Indebtedness or release all or substantially all of the collateral (except as provided in the Loan Documents) supporting any of the US Tranche Commitments or Canadian Tranche Commitments or Loans or Letters of Credit in which such participant is participating. In the case of any such participation, the participant shall not have any rights under this Agreement or any of the Security Instruments (the participant's rights against the granting Lender in respect of such participation to be those set forth in the agreement with such Lender creating such participation); provided, however, participants consent shall be necessary with respect to any amendments which (i) extends the final maturity of the Loans, (ii) increases the Aggregate Commitments, (iii) reduces the interest rate applicable to the Loans or the fees payable to the Lenders generally, (iv) modifies the definition of "Majority Lenders", (v) extends any Letter of Credit beyond its stated termination or (vi) releases all or substantially all of the Collateral and all amounts payable by the Applicable Borrower hereunder shall be determined as if such Lender had not sold such participation, provided that such participant shall be entitled to receive additional amounts under ARTICLE V on the same basis as if it were a Lender and be indemnified under Section 13.03 as if it were a Lender. In addition, each agreement creating any participation must include an agreement by the participant to be bound by the provisions of Section 13.15.

(d) The Lenders may furnish any information concerning a Borrower in the possession of the Lenders from time to time to assignees and participants (including prospective assignees and participants); provided that, such Persons agree to be bound by the provisions of Section 13.15.

(e) Notwithstanding anything in this Section 13.06 to the contrary, any Lender may assign and pledge its Note to any Federal Reserve Bank as collateral security pursuant to Regulation A of the Board of Governors of the Federal Reserve System and any operating circular issued by such Federal Reserve System and/or such Federal Reserve Bank. No such assignment and/or pledge shall release the assigning and/or pledging Lender from its obligations hereunder.

(f) Notwithstanding any other provisions of this Section 13.06, no transfer or assignment of the interests or obligations of any Lender or any grant of participations therein shall be permitted if such transfer, assignment or grant would require either Borrower to file a registration statement with the SEC or to qualify the Loans under the "Blue Sky" laws of any state.

Section 13.07 Invalidity. In the event that any one or more of the provisions contained in any of the Loan Documents or the Letters of Credit, shall, for any reason, be held invalid, illegal or unenforceable in any respect, such invalidity, illegality or unenforceability shall not affect any other provision of the Notes, this Agreement or any Security Instrument.

Section 13.08 Counterparts. This Agreement may be executed in any number of counterparts, all of which taken together shall constitute one and the same instrument and any of the parties hereto may execute this Agreement by signing any such counterpart.

Section 13.10 Survival. The obligations of the parties under Section 4.06, ARTICLE V, and Sections 12.05 and 13.03 shall survive the repayment of the Loans and the termination of the US Tranche Commitments and Canadian Tranche Commitments. To the extent that any payments on the Indebtedness or proceeds of any collateral are subsequently invalidated, declared to be fraudulent or preferential, set aside or required to be repaid to a trustee, debtor in possession, receiver or other Person under any bankruptcy law, common law or equitable cause, then to such extent, the Indebtedness so satisfied shall be revived and continue as if such payment or proceeds had not been received and each Administrative Agent's and the Lenders' Liens, security interests, rights, powers and remedies under this Agreement and each Security Instrument shall continue in full force and effect. In such event, each Security Instrument shall be automatically reinstated and the Applicable Borrower shall take such action as may be reasonably requested by the Applicable Administrative Agent and the Lenders to effect such reinstatement.

(a) THIS AGREEMENT AND THE NOTES SHALL BE GOVERNED BY, AND CONSTRUED IN ACCORDANCE WITH, THE LAWS OF THE STATE OF TEXAS EXCEPT TO THE EXTENT THAT UNITED STATES FEDERAL LAW PERMITS ANY US TRANCHE LENDER TO CHARGE INTEREST AT THE RATE ALLOWED BY THE LAWS OF THE STATE WHERE SUCH LENDER IS LOCATED OR APPLICABLE CANADIAN LAW PERMITS ANY CANADIAN TRANCHE LENDER TO CHARGE INTEREST AT THE RATE ALLOWED BY THE LAWS OF THE JURISDICTION WHERE SUCH LENDER IS LOCATED. CH. 346 OF THE TEXAS FINANCE CODE (WHICH REGULATES CERTAIN REVOLVING CREDIT LOAN ACCOUNTS AND REVOLVING TRI-PARTY ACCOUNTS) SHALL NOT APPLY TO THIS AGREEMENT OR THE NOTES.

(b) ANY LEGAL ACTION OR PROCEEDING WITH RESPECT TO THE LOAN DOCUMENTS SHALL BE BROUGHT IN THE COURTS OF THE STATE OF TEXAS OR OF THE UNITED STATES OF AMERICA FOR THE SOUTHERN DISTRICT OF TEXAS, AND, BY EXECUTION AND DELIVERY OF THIS AGREEMENT, EACH BORROWER HEREBY ACCEPTS FOR ITSELF AND (TO THE EXTENT PERMITTED BY LAW) IN RESPECT OF ITS

PROPERTY, GENERALLY AND UNCONDITIONALLY, THE JURISDICTION OF THE AFORESAID COURTS. EACH BORROWER HEREBY IRREVOCABLY WAIVES ANY OBJECTION, INCLUDING, WITHOUT LIMITATION, ANY OBJECTION TO THE LAYING OF VENUE OR BASED ON THE GROUNDS OF FORUM NON CONVENIENS, WHICH IT MAY NOW OR HEREAFTER HAVE TO THE BRINGING OF ANY SUCH ACTION OR PROCEEDING IN SUCH RESPECTIVE JURISDICTIONS. THIS SUBMISSION TO JURISDICTION IS NON-EXCLUSIVE AND DOES NOT PRECLUDE THE ADMINISTRATIVE AGENTS OR ANY LENDER FROM OBTAINING JURISDICTION OVER EACH BORROWER IN ANY COURT OTHERWISE HAVING JURISDICTION.

(c) EACH BORROWER HEREBY IRREVOCABLY DESIGNATES CT CORPORATION SYSTEM, INC., LOCATED AT 1021 MAIN STREET, SUITE 1150, HOUSTON, TEXAS 77002, AS THE DESIGNEE, APPOINTEE AND ADMINISTRATIVE AGENT OF SUCH BORROWER TO RECEIVE, FOR AND ON BEHALF OF SUCH BORROWER, SERVICE OF PROCESS IN SUCH RESPECTIVE JURISDICTIONS IN ANY LEGAL ACTION OR PROCEEDING WITH RESPECT TO THE LOAN DOCUMENTS.

EACH BORROWER FURTHER IRREVOCABLY CONSENTS TO THE SERVICE OF PROCESS OF ANY OF THE AFOREMENTIONED COURTS IN ANY SUCH ACTION OR PROCEEDING BY THE MAILING OF COPIES THEREOF BY REGISTERED OR CERTIFIED MAIL, POSTAGE PREPAID, TO SUCH BORROWER AT ITS SAID ADDRESS, SUCH SERVICE TO BECOME EFFECTIVE THIRTY (30) DAYS AFTER SUCH MAILING.

(d) NOTHING HEREIN SHALL AFFECT THE RIGHT OF THE ADMINISTRATIVE AGENTS OR ANY LENDER OR ANY HOLDER OF A NOTE TO SERVE PROCESS IN ANY OTHER MANNER PERMITTED BY LAW OR TO COMMENCE LEGAL PROCEEDINGS OR OTHERWISE PROCEED AGAINST THE BORROWERS IN ANY OTHER JURISDICTION.

(e) EACH BORROWER AND EACH LENDER HEREBY (I) IRREVOCABLY AND UNCONDITIONALLY WAIVE, TO THE FULLEST EXTENT PERMITTED BY LAW, TRIAL BY JURY IN ANY LEGAL ACTION OR PROCEEDING RELATING TO THIS AGREEMENT OR ANY SECURITY INSTRUMENT AND FOR ANY COUNTERCLAIM THEREIN; (II) IRREVOCABLY WAIVE, TO THE MAXIMUM EXTENT NOT PROHIBITED BY LAW, ANY RIGHT IT MAY HAVE TO CLAIM OR RECOVER IN ANY SUCH LITIGATION ANY SPECIAL, EXEMPLARY, PUNITIVE OR CONSEQUENTIAL DAMAGES, OR DAMAGES OTHER THAN, OR IN ADDITION TO, ACTUAL DAMAGES; (III) CERTIFY THAT NO PARTY HERETO NOR ANY REPRESENTATIVE OF THE ADMINISTRATIVE AGENTS OR COUNSEL FOR ANY PARTY HERETO HAS REPRESENTED, EXPRESSLY OR OTHERWISE, OR IMPLIED THAT SUCH PARTY WOULD NOT, IN THE EVENT OF LITIGATION, SEEK TO ENFORCE THE FOREGOING WAIVERS, AND (IV) ACKNOWLEDGE THAT IT HAS BEEN INDUCED TO ENTER INTO THIS AGREEMENT, THE SECURITY INSTRUMENTS AND THE TRANSACTIONS CONTEMPLATED HEREBY AND THEREBY BY, AMONG OTHER THINGS, THE MUTUAL WAIVERS AND CERTIFICATIONS CONTAINED IN THIS SECTION 13.13.

Section 13.14 Interest. It is the intention of the parties hereto that each Lender shall conform strictly to usury laws applicable to it. Accordingly, if the transactions contemplated hereby would be usurious as to any Lender under laws applicable to it (including the laws of the United States of America and the State of Texas or any other jurisdiction whose laws may be mandatorily applicable to such Lender notwithstanding the other provisions of this Agreement), then, in that event, notwithstanding anything to the contrary in any of the Loan Documents or any agreement entered into

in connection with or as security for the Notes, it is agreed as follows: (i) the aggregate of all consideration which constitutes interest under law applicable to any Lender that is contracted for, taken, reserved, charged or received by such Lender under any of the Loan Documents or agreements or otherwise in connection with the Notes shall under no circumstances exceed the maximum amount allowed by such applicable law, and any excess shall be canceled automatically and if theretofore paid shall be credited by such Lender on the principal amount of the Indebtedness (or, to the extent that the principal amount of the Indebtedness shall have been or would thereby be paid in full, refunded by such Lender to the Applicable Borrower); and (ii) in the event that the maturity of the Notes is accelerated by reason of an election of the holder thereof resulting from any Event of Default under this Agreement or otherwise, or in the event of any required or permitted prepayment, then such consideration that constitutes interest under law applicable to any Lender may never include more than the maximum amount allowed by such applicable law, and excess interest, if any, provided for in this Agreement or otherwise shall be canceled automatically by such Lender as of the date of such acceleration or prepayment and, if theretofore paid, shall be credited by such Lender on the principal amount of the Indebtedness (or, to the extent that the principal amount of the Indebtedness shall have been or would thereby be paid in full, refunded by such Lender to the Applicable Borrower). All sums paid or agreed to be paid to any Lender for the use, forbearance or detention of sums due hereunder shall, to the extent permitted by law applicable to such Lender, be amortized, prorated, allocated and spread throughout the full term of the Loans evidenced by the Notes until payment in full so that the rate or amount of interest on account of any Loans hereunder does not exceed the maximum amount allowed by such applicable law. If at any time and from time to time (i) the amount of interest payable to any Lender on any date shall be computed at the Highest Lawful Rate applicable to such Lender pursuant to this Section 13.14 and (ii) in respect of any subsequent interest computation period the amount of interest otherwise payable to such Lender would be less than the amount of interest payable to such Lender computed at the Highest Lawful Rate applicable to such Lender, then the amount of interest payable to such Lender in respect of such subsequent interest computation period shall continue to be computed at the Highest Lawful Rate applicable to such Lender until the total amount of interest payable to such Lender shall equal the total amount of interest which would have been payable to such Lender if the total amount of interest had been computed without giving effect to this Section 13.14. To the extent that Chapter 303 of the Texas Finance Code is relevant for the purpose of determining the Highest Lawful Rate, such Lender elects to determine the applicable rate ceiling under such Chapter by the indicated weekly rate ceiling from time to time in effect.

Section 13.15 Confidentiality. For the purposes of this Section 13.15, "Confidential Information" means information about the Borrowers furnished by the Borrowers or their Affiliates (collectively, the "Disclosing Parties") to the Administrative Agents or any of the Lenders, including, but not limited to, any actual or pending agreement, business plans, ecological data and accounting records, financial statements, or other financial data of any kind, any title documents, reports or other information relating to matters of title, any projects or plans, whether actual or prospective, and any other documents or items embodying any such Confidential Information; provided that such term does not include information that (a) was publicly known or otherwise known prior to the time of such disclosure, (b) subsequently becomes publicly known through no act or omission by the Administrative Agents or the Lenders or any Person acting on behalf thereof, (c) otherwise becomes known to the Administrative Agents or Lenders other than through disclosure by the Disclosing Parties or (d) constitutes financial statements delivered to the Administrative Agents and the Lenders under Section 9.01(a) that are otherwise publicly available. The Administrative Agents and the Lenders will maintain the confidentiality of such Confidential Information delivered to (i) such Person, provided that each such Person (a "Restricted Person") may deliver or disclose Confidential Information to such Restricted Person's directors, officers, employees, agents, attorneys and affiliates, who agree to hold confidential the Confidential Information substantially in accordance with the terms of this Section 13.15, (ii) such Restricted Person's financial advisors and other professional advisors who agree

to hold confidential the Confidential Information substantially in accordance with the terms of this Section 13.15, (iii) any other Lender, (iv) any assignee to which such Restricted Person sells or offers to sell its Note or any part thereof or any participation therein (if such Person has agreed in writing prior to its receipt of such Confidential Information to be bound by the provisions of this Section 13.15), (v) any Person from which such Restricted Person offers to purchase any security of the Borrowers (if such Person has agreed in writing prior to its receipt of such Confidential Information to be bound by the provisions of this Section 13.15), (vi) any Governmental Authority having jurisdiction or any self-regulatory body claiming to have authority over such Restricted Person, (vii) the National Association of Insurance Commissioners or any similar organization, or any nationally recognized rating agency that requires access to information about such Restricted Person's investment portfolio, or (viii) any other Person to which such delivery or disclosure may be necessary or appropriate (w) to effect compliance with any Governmental Requirement applicable to such Restricted Person, (x) in response to any subpoena or other legal process, (y) in connection with any litigation to which such Restricted Person is a party or (z) if an Event of Default has occurred and is continuing, to the extent such Restricted Person may reasonably determine such delivery and disclosure to be necessary or appropriate in the enforcement or for the protection of its rights and remedies under the Notes and this Agreement. Each Lender, by its acceptance of a Note, will be deemed to have agreed to be bound by and to be entitled to the benefits of this Section 13.15 as though it were a party to this Agreement. On reasonable request by the Borrowers in connection with the delivery to any Lender of information required to be delivered to such Lender under this Agreement or requested by such Lender (other than a Lender that is a party to this Agreement or its nominee), such Lender will enter into an agreement with the Borrowers embodying the provisions of this Section 13.15. Each Borrower waives (on its own behalf and on behalf of its Subsidiaries) any and all other rights it (or its Subsidiaries) may have to confidentiality as against the Administrative Agents and the Lenders arising by or under any contract, agreement, statute or law except as expressly stated in this Section 13.15.

Section 13.16 Effectiveness. This Agreement shall be effective on the Closing Date.

Section 13.17 EXCULPATION PROVISIONS. EACH OF THE PARTIES HERETO SPECIFICALLY AGREES THAT IT HAS A DUTY TO READ THIS AGREEMENT AND THE SECURITY INSTRUMENTS AND AGREES THAT IT IS CHARGED WITH NOTICE AND KNOWLEDGE OF THE TERMS OF THIS AGREEMENT AND THE SECURITY INSTRUMENTS; THAT IT HAS IN FACT READ THIS AGREEMENT AND IS FULLY INFORMED AND HAS FULL NOTICE AND KNOWLEDGE OF THE TERMS, CONDITIONS AND EFFECTS OF THIS AGREEMENT; THAT IT HAS BEEN REPRESENTED BY INDEPENDENT LEGAL COUNSEL OF ITS CHOICE THROUGHOUT THE NEGOTIATIONS PRECEDING ITS EXECUTION OF THIS AGREEMENT AND THE SECURITY INSTRUMENTS; AND HAS RECEIVED THE ADVICE OF ITS ATTORNEY IN ENTERING INTO THIS AGREEMENT AND THE SECURITY INSTRUMENTS; AND THAT IT RECOGNIZES THAT CERTAIN OF THE TERMS OF THIS AGREEMENT AND THE SECURITY INSTRUMENTS RESULT IN ONE PARTY ASSUMING THE LIABILITY INHERENT IN SOME ASPECTS OF THE TRANSACTION AND RELIEVING THE OTHER PARTY OF ITS RESPONSIBILITY FOR SUCH LIABILITY. EACH PARTY HERETO AGREES AND COVENANTS THAT IT WILL NOT CONTEST THE VALIDITY OR ENFORCEABILITY OF ANY EXCULPATORY PROVISION OF THIS AGREEMENT AND THE SECURITY INSTRUMENTS ON THE BASIS THAT THE PARTY HAD NO NOTICE OR KNOWLEDGE OF SUCH PROVISION OR THAT THE PROVISION IS NOT "CONSPICUOUS."

Section 13.18 Hedging Agreements. Notwithstanding anything to the contrary contained herein, the terms and provisions of this Agreement shall not apply to any Hedging Agreements, except to the extent necessary for all Hedging Agreements with Lenders and/or their Affiliates to be secured by the Security Instruments on a pari passu basis with other Indebtedness and for the proceeds from the Security Instruments to be applied as set forth in Section 11.02(c) hereof.

Section 13.19 USA Patriot Act Notice. Each US Tranche Lender hereby notifies the Borrowers that pursuant to the requirements of the USA Patriot Act (Title III of Pub. L. 107-56 (signed into law October 26, 2001)) (the "USA Patriot Act"), it is required to obtain, verify and record information that identifies the US Borrower and its Subsidiaries, which information includes the name and address of the US Borrower and such Subsidiaries and other information that will allow such US Tranche Lender to identify the US Borrower and such Subsidiaries in accordance with the USA Patriot Act.

Section 13.20 Restatement. This Agreement amends, restates and supercedes the Credit Agreement. It is the intention of the parties that all liens and security interests securing the Credit Agreement continue to exist, remain valid and shall not be impaired or released hereby and shall remain in full force and effect as provided in the Security Instruments.

ARTICLE XIV

Section 14.01 The Guaranty.

(a) The Guarantor irrevocably and unconditionally guarantees to each Canadian Tranche Lender and the Administrative Agents and their respective successors and permitted assigns, (i) the full and punctual payment of principal and interest on each Canadian Tranche Loan when due, whether at maturity, by acceleration, by redemption or otherwise and (ii) the full and punctual performance within applicable grace periods of all other obligations of the Canadian Borrower under this Agreement (collectively, the "Guaranteed Obligations").

(b) The Guarantor further agrees that this Guaranty constitutes an absolute, irrevocable, complete and continuing guarantee of payment, performance and compliance and not merely of collection.

(c) The obligations of the Guarantor to make any payment hereunder may be satisfied by causing the Canadian Borrower to make such payment.

(d) The Guarantor also agrees to pay any and all costs and expenses (including reasonable attorneys' fees incurred by any Administrative Agent or any Canadian Tranche Lender in enforcing any of their respective rights under this Guaranty, laws or otherwise) of each Administrative Agent or any Canadian Tranche Lender against the Canadian Borrower or any other Person or against such Administrative Agent or any Canadian Tranche Lender for their payments in respect of any amounts to any Canadian Tranche Lender pursuant to the provisions of this Guaranty.

(e) The Guarantor waives presentment to, demand of payment from and protest to the Canadian Borrower of any of the Guaranteed Obligations, and also waives notice of acceptance of its guarantee and notice of protest for nonpayment. The obligations of the Guarantor hereunder shall not be affected by the failure of either Administrative Agent or any Canadian Tranche Lender to assert any claim or demand or to enforce or exercise any right or remedy against the Canadian Borrower or any other Person under the provisions of this Agreement, any other Loan Document or otherwise.

(f) To the fullest extent permitted by applicable law, the obligations of the Guarantor hereunder are absolute and unconditional and shall not be subject to any reduction, limitation, impairment or termination for any reason (other than the payment in full in cash of all the Guaranteed Obligations), including any claim of waiver, release, surrender, alteration or compromise of any of the Guaranteed Obligations, and shall not be subject to any defense (other than a defense of payment or performance), set-off, counterclaim, recoupment or termination whatsoever by reason of the invalidity, illegality or unenforceability of the Guaranteed Obligations or any Note, other Loan Document or otherwise.

(g) The Guarantor waives any defense based on or arising out of any defense of the Canadian Borrower or the unenforceability of the Guaranteed Obligations or any part thereof from any cause, or the cessation from any cause of the liability of the Canadian Borrower, other than the final payment in full in cash of all the Guaranteed Obligations.

(h) To the fullest extent permitted by applicable law, this Guaranty shall continue to be effective or be reinstated, as the case may be, if at any time any payment of the Guaranteed Obligations is rescinded or must otherwise be returned by any of the Canadian Tranche Lenders upon the insolvency, bankruptcy or reorganization or the Canadian Borrower or otherwise, all as though such payment had not been made.

Section 14.02 Subrogation. The Guarantor shall be subrogated to any of the rights (whether contractual, under applicable laws or otherwise) of either Administrative Agent or any Canadian Tranche Lender against the Canadian Borrower or any other Person for the payments in respect of any amounts to any Canadian Tranche Lender pursuant to the provisions of this Guaranty; provided, however, that the Guarantor shall not be entitled to enforce, or to receive any payments arising out of or based upon, such right of subrogation until all other Guaranteed Obligations shall have been paid in full and the Aggregate Canadian Tranche Commitments terminated.

The parties hereto have caused this Agreement to be duly executed as of the day and year first above written.
