period from the Effective Date to, but not including, the Revolving Commitment Termination Date,
each US Tranche Lender severally agrees to make US Tranche Revolving Loans to the US Borrower in an
aggregate principal amount that will not result in (A) such Lender’s US Tranche Revolving Credit
Exposure exceeding such Lender’s US Tranche Commitment, (B) the sum of the total US Tranche
Revolving Credit Exposure exceeding the total US Tranche Commitments, or (C) the Combined Credit
Exposure exceeding the total Revolving Commitments. Within the foregoing limits, the US Borrower

               (ii) Subject to the terms and conditions of this Agreement, from time to time during the
period from the Effective Date to, but not including, the Revolving Commitment Termination Date,
each Canadian Tranche Lender severally agrees to make

18

 

Canadian Tranche Revolving Loans (including
BA Loans made in accordance with Section 2.24) to the Canadian Borrower, and each Accepting Lender
agrees to accept Bankers’ Acceptances presented to it by the Canadian Borrower, subject to Section
2.24, in an aggregate amount that will not result in (A) such Lender’s Canadian Tranche Revolving
Credit Exposure exceeding such Lender’s Canadian Tranche Commitment, (B) the sum of the total
Canadian Tranche Revolving Credit Exposures exceeding the total Canadian Tranche Commitments, or
(C) the Combined Credit Exposure exceeding the total Revolving Commitments. Within the foregoing

with the terms and conditions hereof, and the Canadian Borrower may repay (but not prepay) Bankers’
Acceptances and present new Bankers’ Acceptances for acceptance by the Accepting Lenders, all in
accordance with the terms and conditions hereof.

          (b) Reserved.

          (c) Each Loan (other than a BA Loan made in accordance with Section 2.24) of each Tranche
shall be made only during the Revolving Period as part of a Borrowing consisting of Revolving Loans
made by the US Tranche Lenders or Canadian Tranche Lenders, as the case may be, ratably in
accordance with their US Tranche Commitments or Canadian Tranche Commitments, as the case may be.
The failure of any Lender to make any Loan required to be made by it shall not relieve any other
Lender of its obligations hereunder, provided that the Commitments of the Lenders are several and
no Lender shall be responsible for any other Lender’s failure to make Loans as required.

          (d) Subject to Section 2.17, the Loans may be (i) Eurodollar Loans, (ii) Alternate Base Rate
Loans, (iii) Canadian Base Rate Loans, (iv) Canadian Prime Rate Loans, or (v) a combination
thereof, as determined by the respective Borrower, or shall be comprised of Bankers’ Acceptances
and BA Loans made in accordance with Section 2.24, as notified to the Canadian Administrative Agent
in accordance with Section 2.03 and Section 2.10. Eurodollar Loans shall be made and maintained by
each Lender at either its Eurodollar Lending Office or its Domestic Lending Office, at its option,
provided that the exercise of such option shall not affect the obligation of the Applicable
Borrower to repay such Loan in accordance with the terms of this Agreement or create or increase
any obligation of any Borrower not otherwise arising, or arising in such increased amount, under
Section 2.14.

          (e) No Person shall be permitted to be (or become) a Canadian Tranche Lender under this
Agreement unless such Person is, for the purposes of the Income Tax Act (Canada) in force as of the
date that such Lender acquires a Canadian Tranche Commitment, either (i) not a non-resident of
Canada for purposes of the Income Tax Act (Canada), or (ii) a deemed resident of Canada for
purposes of Part XIII of the Income Tax Act (Canada) which has,
as part of its business carried on in Canada a Canadian Tranche Commitment, and, in the case
of clauses (i) and (ii), is an Affiliate of a US Tranche Lender.

     Section 2.02 Repayment of Loans; Evidence of Debt.

          (a) Each Applicable Borrower hereby unconditionally promises to pay to the Applicable
Administrative Agent for the account of each Applicable Lender the then unpaid

19

 

principal and
accrued interest amount of each Loan on the Maturity Date, or such earlier date upon which the
maturity of the Loans shall have been accelerated pursuant to ARTICLE VII.

          (b) Each Lender shall maintain in accordance with its usual practice an account or accounts
evidencing the indebtedness of a Borrower to such Lender resulting from each Loan made by such
Lender, including the amounts of principal and interest payable and paid to such Lender from time
to time hereunder.

          (c) Each Administrative Agent shall maintain accounts in which it shall record (i) the amount
of each Loan made hereunder, the Type and Tranche thereof and the Interest Period applicable
thereto, (ii) the amount of any principal or interest due and payable or to become due and payable
from each Borrower to each Lender hereunder, and (iii) the amount of any sum received by such
Administrative Agent hereunder for the account of the Lenders and each Lender’s share thereof.

          (d) The entries made in the accounts maintained pursuant to paragraph (b) and (c) of this
Section 2.02 shall be prima facie evidence of the existence and amounts of the obligations recorded
therein; provided that the failure of any Lender or an Administrative Agent to maintain such
accounts or any error therein shall not in any manner affect the obligation of each Borrower to
repay the Loans in accordance with the terms of this Agreement.

          (e) Any Lender may request that Loans made by it to a Borrower be evidenced by a promissory
note. In such event, the Applicable Borrower shall prepare, execute and deliver to such Lender a
promissory note payable to the order of such Lender in substantially the form attached hereto as
Exhibit A. Thereafter, the Loans evidenced by such Note and interest thereon shall, at all
times (including after assignment pursuant to Section 9.04), be represented by one or more Notes in
such form payable to the order of the payee named therein.

          (f) Each Lender is authorized to and shall endorse the date, Type, Tranche and amount of each
Loan made by such Lender, each continuation thereof, each conversion of all or a portion thereof to
the same or another Type, and the date and amount of each payment of principal with respect thereto
on the schedule annexed to and constituting a part of its Note from a Borrower. No failure to make
or error in making any such endorsement as authorized hereby shall affect the validity of the
obligations of each Borrower to repay the unpaid Principal Amount of the Loans made to such
Borrower with interest thereon as provided in Section 2.10 or the validity of any payment thereof
made by each Borrower. Each Applicable Lender shall, at the request of an Applicable Borrower,
deliver to such Borrower copies of such Borrower’s Note and the schedules annexed thereto.

     Section 2.03 Procedure for Borrowing. Each Borrower may borrow Loans on any Business Day; provided that
such Borrower shall notify the
Applicable Administrative Agent by telephone of the Borrowing (the “Borrowing Request”) not later
than 2:00 p.m., New York City time (a) three (3) Business Days prior to the Borrowing Date, in the
case of Eurodollar Loans, and (b) the Borrowing Date, in the case of Alternate Base Rate Loans,
Canadian Base Rate Loans or Canadian Prime Rate Loans. Each telephonic Borrowing Request shall be
irrevocable and shall be confirmed promptly by hand delivery or telecopy to the Applicable
Administrative Agent of a written Borrowing Request in a form approved by the Applicable
Administrative

20

 

Agent and signed by the Requesting Borrower. Each such telephonic and written
Borrowing Request shall specify (i) the amount to be borrowed, (ii) the Borrowing Date, (iii)
whether the Borrowing is to consist of Eurodollar Loans, Alternate Base Rate Loans, Canadian Base
Rate Loans, Canadian Prime Rate Loans, or a combination thereof (in each case stating the amounts
and currency requested), (iv) in the case of Eurodollar Loans, the length of the Interest Period(s)
therefor, and (v) the location and number of the Requesting Borrower’s account to which funds are
to be disbursed, which shall comply with the requirements of Section 2.12. Each Borrowing shall be
in an aggregate principal amount not less than the lesser of (i) $10,000,000 or a whole multiple of
$5,000,000 in excess thereof, and (ii) the then unused Commitments available to the Requesting
Borrower. Upon receipt of such notice, the Applicable Administrative Agent shall promptly notify
each Applicable Lender thereof. Each Applicable Lender will make the amount of its pro rata share
of each Borrowing available to the Applicable Administrative Agent for the account of the
Requesting Borrower in accordance with Section 2.12. The proceeds of each such Borrowing of
Revolving Loans will be made available to the Requesting Borrower by the Applicable Administrative
Agent in accordance with Section 2.12. Notwithstanding the foregoing, all Borrowings by way of
Bankers’ Acceptances and BA Loans shall be made pursuant to Section 2.24.

     Section 2.04 Facility Fees, Utilization Fees and LC Fees.

          (a) Subject to Section 2.04(e), each Applicable Borrower agrees to pay to the Applicable
Administrative Agent for the account of each Applicable Lender a Facility Fee from the Effective
Date to, but not including, the Maturity Date or such earlier date upon which the Commitments shall
terminate or be reduced to zero as provided herein, computed at the Facility Fee Rate on the daily
amount of the Commitment of such Lender (whether used or unused) (the “Facility Fee”); provided
that, if such Lender continues to have any Credit Exposure after its Commitment terminates, then
such Facility Fee shall continue to accrue on the daily amount of such Lender’s Credit Exposure
from and including the date on which its Commitment terminates to, but not including, the date on
which such Lender ceases to have any Credit Exposure.

          (b) Subject to Section 2.04(e), the Applicable Borrower agrees to pay to the Applicable
Administrative Agent for the account of each Applicable Lender at all times when the Combined
Credit Exposure is greater than or equal to 50% of the availability under the total Commitment a
Utilization Fee computed at the Utilization Fee Rate on the daily amount of the Credit Exposure of
such Lender (the “Utilization Fee”).

          (c) Reserved.

          (d) Each Applicable Borrower agrees to pay (i) to the Applicable Administrative Agent for the
account of each Applicable Lender a participation fee with respect to its participations in Letters
of Credit, which shall accrue at the same rate as the Eurodollar Margin on the average daily amount
of such Lender’s LC Exposure to such Borrower (excluding any portion thereof attributable to
unreimbursed LC Disbursements) during the period from and including the Effective Date to but
excluding the later of the date on which such Lender’s Commitment terminates and the date on which
such Lender ceases to have any LC Exposure, and (ii) to any Issuing Bank an issuing fee payable on
the date a Letter of Credit is issued, which shall be the normal issuing fee for letters of credit
issued by such Issuing Bank, not to be less

21

 

than the greater of $500 or 0.0125% times the face
amount of such Letter of Credit (collectively, the “LC Fees”).

          (e) If any Lender shall become a Defaulting Lender, then, notwithstanding Section 2.04(a) and
Section 2.04(b) above and without prejudicing any right or remedy that any Borrower may have with
respect to, on account of, arising from or relating to any event pursuant to which such Lender
shall be a Defaulting Lender, no Facility Fee or Utilization Fee shall accrue for the account of
such Lender from and after the date upon which such Lender shall have become a Defaulting Lender.

          (f) Facility Fees, Utilization Fees and LC Fees shall be payable quarterly in arrears on the
last day of each March, June, September and December, commencing on September 30, 2004, and on the
Maturity Date or, with respect to Facility Fees, on such earlier date as the Commitments shall
terminate or be reduced to zero as provided herein. All accrued Facility Fees, Utilization Fees
and LC Fees which are not paid on or before the Maturity Date shall be due and payable on demand.

     Section 2.05 Letters of Credit.

          (a) Subject to the terms and conditions set forth herein, each Borrower may request the
issuance of Letters of Credit for its own account, in a form reasonably acceptable to the
Applicable Administrative Agent and the Issuing Bank, at any time and from time to time prior to
the Revolving Commitment Termination Date. In the event of (i) any inconsistency between the terms
and conditions of this Agreement and the terms and conditions of any form of letter of credit
application or other agreement submitted by the Requesting Borrower to, or entered into by the
Requesting Borrower with, an Issuing Bank relating to any Letter of Credit, or (ii) any terms and
conditions supplemental to the terms and conditions of this Agreement contained in any such form of
letter of credit application or such other agreement, in each case, the terms and conditions of
this Agreement shall control and such supplemental terms and conditions shall be ignored.

          (b) To request the issuance of a Letter of Credit (or the amendment, renewal or extension of
an outstanding Letter of Credit), the Requesting Borrower shall hand deliver or telecopy (or
transmit by electronic communication, if arrangements for doing so have been
approved by the Issuing Bank) to the appropriate Issuing Bank and the Administrative Agents
(reasonably in advance of the requested date of issuance, amendment, renewal or extension) a notice
requesting the issuance of a Letter of Credit, or identifying the Letter of Credit to be amended,
renewed or extended, and specifying the date of issuance, amendment, renewal or extension (which
shall be a Business Day), the date on which such Letter of Credit is to expire (which shall comply
with Section 2.05(c)), the amount of such Letter of Credit, the name and address of the beneficiary
thereof and such other information (including, if applicable, the currency of such Letter of
Credit, which shall be US Dollars or Canadian Dollars) as shall be necessary to prepare, amend,
renew or extend such Letter of Credit. If requested by an Issuing Bank, the Requesting Borrower
also shall submit a letter of credit application on such Issuing Bank’s standard form in connection
with any request for a Letter of Credit. A Letter of Credit shall be issued, amended, renewed or
extended only if (and upon issuance, amendment, renewal or extension of each Letter of Credit the
Requesting Borrower shall be deemed to represent and

22

 

warrant that), after giving effect to such
issuance, amendment, renewal or extension and the continuation of an Existing Letter of Credit
hereunder (i) the LC Exposure shall not exceed the unused Commitment available under the applicable
Tranche and (ii) the sum of the Combined Credit Exposure shall not exceed the sum of the total
Commitments; provided that the Issuing Bank shall not issue, amend, renew or extend any Letter of
Credit if the Issuing Bank shall have received written notice (which has not been rescinded) from
the Applicable Administrative Agent or any Lender that any applicable condition precedent to the
issuance, amendment, renewal or extension of such Letter of Credit has not been satisfied at the
requested time of issuance, amendment, renewal or extension of such Letter of Credit.

          (c) Each Letter of Credit shall expire at or prior to the close of business on the date
selected by the Requesting Borrower, which shall not be later than the earlier of (i) the date one
year after the date of the issuance of such Letter of Credit (or, in the case of any renewal or
extension thereof, one year after such renewal or extension), and (ii) the date that is five (5)
Business Days prior to the Maturity Date.

          (d) By the issuance of a Letter of Credit (or an amendment to a Letter of Credit increasing
the amount thereof) and the continuation hereunder of each of the Existing Letters of Credit and
without any further action on the part of an Issuing Bank or the Applicable Lenders, such Issuing
Bank hereby grants to each Applicable Lender, and each such Lender hereby acquires from such
Issuing Bank, a participation in such Letter of Credit equal to such Lender’s Applicable Percentage
of the aggregate amount available to be drawn under such Letter of Credit. In consideration and in
furtherance of the foregoing, each Applicable Lender hereby absolutely and unconditionally agrees
to pay to the Applicable Administrative Agent, for the account of such Issuing Bank in the currency
in which such Letter of Credit is denominated, such Lender’s Applicable Percentage of each LC
Disbursement made by such Issuing Bank and not reimbursed by the Applicable Borrower on the date
due as provided in Section 2.05(e), or of any reimbursement payment required to be refunded to such
Applicable Borrower for any reason. Each Lender acknowledges and agrees that its obligation to
acquire participations pursuant to this paragraph in respect of Letters of Credit is absolute and
unconditional and shall not be affected by any circumstance whatsoever, including any amendment,
renewal or extension of any Letter of Credit or the occurrence and continuance of an Event of
Default or reduction or termination of the Commitments, and that each such payment shall be made
without any offset, abatement, withholding or reduction whatsoever.

          (e) If an Issuing Bank shall make any LC Disbursement in respect of a Letter of Credit, the
Applicable Borrower shall reimburse such LC Disbursement in the currency in which such Letter of
Credit is denominated by paying to the Applicable Administrative Agent an amount equal to such LC
Disbursement not later than 12:00 noon, New York City time, on (i) the Business Day that such
Applicable Borrower receives a notice of such LC Disbursement from the Applicable Administrative
Agent, if such notice is received prior to 10:00 a.m., New York City time, on the day of receipt,
or (ii) the Business Day immediately following the day that such Applicable Borrower receives a
notice of such LC Disbursement from the Applicable Administrative Agent, if such notice is not
received prior to such time on the day of receipt; provided that, with respect to any such payment
owing by the Applicable Borrower prior to the Revolving Commitment Termination Date, such
Applicable Borrower may, subject to the conditions to borrowing set forth herein, request in
accordance with Section 2.03 that such

23

 

payment be financed with an Alternate Base Rate Borrowing,
in the case of the US Borrower, or a Canadian Prime Rate Borrowing or Canadian Base Rate Borrowing,
in the case of the Canadian Borrower, in an equivalent amount and, to the extent so financed, the
Applicable Borrower’s obligation to make such payment shall be discharged and replaced by the
resulting Borrowing. If the Applicable Borrower fails to make such payment when due, the
Applicable Administrative Agent shall notify each Applicable Lender of the applicable LC
Disbursement, the payment then due from such Applicable Borrower in respect thereof and such
Lender’s Applicable Percentage thereof. Promptly following receipt of such notice, each Applicable
Lender shall pay to the Applicable Administrative Agent its Applicable Percentage of the payment
then due from the Applicable Borrower, in the same manner as provided in Section 2.12 with respect
to Loans made by such Lender in the appropriate currency (and Section 2.12 shall apply, mutatis
mutandis, to the payment obligations of the Lenders), and the Applicable Administrative Agent shall
promptly pay to such Issuing Bank the amounts so received by such Applicable Administrative Agent
from the Applicable Lenders. Promptly following receipt by the Applicable Administrative Agent of
any payment from an Applicable Borrower pursuant to this paragraph, the Applicable Administrative
Agent shall distribute such payment to the Issuing Bank or, to the extent that the Applicable
Lenders have made payments pursuant to this paragraph to reimburse the Issuing Bank, then to such
Lenders and the Issuing Bank as their interests may appear. Any payment made by an Applicable
Lender pursuant to this paragraph to reimburse an Issuing Bank for any LC Disbursement shall not
constitute a Loan and shall not relieve the Applicable Borrower of its obligation to reimburse such
LC Disbursement.

          (f) To the extent permitted by law, each Borrower’s obligation to reimburse LC Disbursements
as provided in Section 2.05(e) shall be absolute, unconditional and irrevocable, and shall be
performed strictly in accordance with the terms of this Agreement under any and all circumstances
whatsoever and irrespective of (i) any lack of validity or enforceability of any Letter of Credit
or this Agreement, or any term or provision therein, (ii) any draft or other document presented
under a Letter of Credit proving to be forged, fraudulent or invalid in any respect or any
statement therein being untrue or inaccurate in any respect, (iii) payment by the Issuing Bank
under a Letter of Credit against presentation of a draft or other document that does not comply
with the terms of such Letter of Credit, or (iv) any other event or circumstance whatsoever,
whether or not similar to any of the foregoing, that might, but for the provisions of this Section,
constitute a legal or equitable discharge of, or provide a right of setoff against, such Borrower’s
obligations hereunder. To the extent permitted by law, none of the Administrative Agents, the
Lenders, or the Issuing Banks, or any of their Related Parties, shall have any liability
or responsibility by reason of or in connection with the issuance or transfer of any Letter of
Credit or any payment or failure to make any payment thereunder (irrespective of any of the
circumstances referred to in the preceding sentence), or any error, omission, interruption, loss or
delay in transmission or delivery of any draft, notice or other communication under or relating to
any Letter of Credit (including any document required to make a drawing thereunder), any error in
interpretation of technical terms or any consequence arising from causes beyond the control of an
Issuing Bank; provided that the foregoing shall not be construed to excuse any Issuing Bank from
liability to an Applicable Borrower to the extent of any direct damages (as opposed to
consequential damages, claims in respect of which are hereby waived by the Borrowers to the extent
permitted by applicable law) suffered by such Borrower that are caused by such Issuing Bank’s
failure to exercise care when determining whether drafts and other documents presented under a
Letter of Credit comply with the terms thereof. To the extent permitted by law, the

24

 

parties hereto
expressly agree that, in the absence of gross negligence or willful misconduct on the part of an
Issuing Bank, such Issuing Bank shall be deemed to have exercised care in each such determination.
In furtherance of the foregoing and without limiting the generality thereof, the parties agree
that, with respect to documents presented which appear on their face to be in substantial
compliance with the terms of a Letter of Credit, the Issuing Bank may, in its sole discretion,
either accept and make payment upon such documents without responsibility for further
investigation, regardless of any notice or information to the contrary, or refuse to accept and
make payment upon such documents if such documents are not in strict compliance with the terms of
such Letter of Credit.

          (g) The Issuing Bank shall, promptly following its receipt thereof, examine all documents
purporting to represent a demand for payment under a Letter of Credit. The Issuing Bank shall
promptly notify the Applicable Administrative Agent and the Applicable Borrower by telephone
(confirmed by telecopy) of such demand for payment and whether the Issuing Bank has made or will
make an LC Disbursement thereunder; provided that any failure to give or delay in giving such
notice shall not relieve such Applicable Borrower of its obligation to reimburse the Issuing Bank
and the Applicable Lenders with respect to any such LC Disbursement.

          (h) If an Issuing Bank shall make any LC Disbursement, then, unless the Applicable Borrower
shall reimburse such LC Disbursement in full on the date specified in Section 2.05(e), the unpaid
amount thereof shall bear interest, for each day from and including the date such reimbursement is
due pursuant to Section 2.05(e) to but excluding the date that such Applicable Borrower reimburses
such LC Disbursement, at the rate per annum then applicable to Alternate Base Rate Loans, in the
case of Letters of Credit issued for the account of the US Borrower, and Canadian Base Rate Loans
or Canadian Prime Rate Loans, as applicable, in the case of Letters of Credit issued for the
account of the Canadian Borrower; provided that, if an Applicable Borrower fails to reimburse such
LC Disbursement when due pursuant to Section 2.05(e), then the provisions of Section 2.10(a)
pertaining to interest payable on overdue principal shall apply. Interest accrued pursuant to this
paragraph shall be for the account of the applicable Issuing Bank, except that interest accrued on
and after the date of payment by any Lender pursuant to Section 2.05(e) to reimburse such Issuing
Bank shall be for the account of such Lender to the extent of such payment.

          (i) Any Issuing Bank with respect to a Tranche may be replaced at any time by written
agreement among the Applicable Borrower, the Applicable Administrative Agent, the
replaced Issuing Bank and the successor Issuing Bank. The Applicable Administrative Agent
shall notify the Applicable Lenders of any such replacement of an Issuing Bank. At the time any
such replacement shall become effective, the Applicable Borrower shall pay all unpaid fees accrued
for the account of the replaced Issuing Bank. From and after the effective date of any such
replacement, (i) the successor Issuing Bank shall have all the rights and obligations of the
Issuing Bank under this Agreement with respect to Letters of Credit to be issued thereafter, and
(ii) references herein to the term “Issuing Bank” shall be deemed to refer to such successor or to
any previous Issuing Bank with respect to the Canadian Tranche or the US Tranche, as the case may
be, or to such successor and all previous Issuing Banks, as the context shall require. After the
replacement of any Issuing Bank hereunder, the replaced Issuing Bank shall remain a party hereto
and shall continue to have all the rights and obligations of an Issuing Bank under this

25

 

Agreement
with respect to Letters of Credit issued by it prior to such replacement, but shall not be required
to issue additional Letters of Credit.

          (j) (i) If any Event of Default shall occur and be continuing, on the Business Day that an
Applicable Borrower receives notice from Lenders with LC Exposure representing greater than 662/3% of
the total LC Exposure or, if the maturity of the Loans has been accelerated, from the Applicable
Administrative Agent or the Majority Lenders, demanding the deposit of cash collateral pursuant to
this paragraph, and (ii) on the Business Day that an Applicable Borrower receives notice from
either the Administrative Agent acting alone or the Majority Lenders demanding deposit of cash
collateral pursuant to Section 2.08(b) (or, if such notice is received on a day other than a
Business Day, on the next Business Day following receipt of such notice), the Applicable Borrower
shall deposit in an account with the Applicable Administrative Agent, in the name of the Applicable
Administrative Agent and for the benefit of the Applicable Lenders, an amount in cash (in the
applicable currency) equal to the US LC Exposure or the Canadian LC Exposure, as applicable, as of
such date plus any accrued and unpaid interest thereon; provided that the obligation to deposit
such cash collateral shall become effective immediately, and such deposit shall become immediately
due and payable, without demand or other notice of any kind, upon the occurrence of any Event of
Default with respect to the Applicable Borrower described in Section 7.01(g) and Section 7.01(h).
Such deposit shall be held by the Applicable Administrative Agent as collateral for the payment and
performance of the obligations of the Applicable Borrower under this Agreement. The Applicable
Administrative Agent shall have exclusive dominion and control, including the exclusive right of
withdrawal, over such account. Other than any interest earned on the investment of such deposits,
which investments shall be made in certificates of deposits of the Applicable Administrative Agent
or securities backed by the full faith and credit of the United States of America or Canada, at the
option of the Applicable Administrative Agent and at the Applicable Borrower’s risk and expense,
such deposits shall not bear interest. Interest or profits, if any, on such investments shall
accumulate in such account. Monies in such account shall be applied by the Applicable
Administrative Agent to reimburse each applicable Issuing Bank for LC Disbursements for which it
has not been reimbursed and, to the extent not so applied, shall be held for the satisfaction of
the reimbursement obligations of the Applicable Borrower for the US LC Exposure or the Canadian LC
Exposure, as applicable, at such time or, if the maturity of the Loans has been accelerated (but
subject to the consent of the Majority Lenders), be applied to satisfy other obligations of such
Applicable Borrower under this Agreement. If an Applicable Borrower is required to provide an
amount of cash collateral hereunder as a result of the occurrence of an Event of Default, such
amount (to the extent not applied as aforesaid) shall be
returned to such Applicable Borrower within two (2) Business Days after all Events of Default
have been cured or waived.

          (k) The Existing Letters of Credit shall automatically be deemed to have been issued under
this Agreement as of the Effective Date, and except as otherwise indicated herein, the terms and
provisions of the Existing Credit Agreement shall thereafter have no force or effect with respect
thereto.

     Section 2.06 Reduction or Termination of Commitments. Unless previously terminated, the Commitments shall terminate on the Revolving Commitment
Termination Date. The US Borrower shall have the right, upon not less than two (2) Business Days’
notice to the

26

 

Applicable Administrative Agent, to terminate the US Tranche Commitments or the
Canadian Tranche Commitments, as applicable, or, from time to time, reduce the amount of the US
Tranche Commitments or the Canadian Tranche Commitments, as applicable; provided, however, that the
US Borrower shall not terminate or reduce any Commitment if, after giving effect to any concurrent
repayment of the Loans in accordance with Section 2.07 and Section 2.08 the sum of the Combined
Credit Exposures would exceed the sum of total Commitments. Any reduction shall be accompanied by
prepayment of the Loans to the extent, if any, that the sum of the Credit Exposures of the
Applicable Lenders then outstanding exceeds the sum of the total US Tranche Commitments or the
Canadian Tranche Commitments, as applicable, as then reduced. Any termination of the Commitments
shall be accompanied by prepayment in full of the Loans then outstanding and the payment of any
unpaid fees then accrued hereunder. Upon receipt of such notice, the Applicable Administrative
Agent shall promptly notify each Applicable Lender thereof. Any partial reduction shall be in an
amount of $5,000,000 or a whole multiple thereof and shall reduce permanently the total amount of
the US Tranche Commitments or the Canadian Tranche Commitments, as applicable, and the Commitments
then in effect, together with a corresponding reduction in the aggregate amount of each Lender’s
applicable Commitment. The Commitments once terminated or reduced may not be reinstated. Each
reduction of the US Tranche Commitments or the Canadian Tranche Commitments, as the case may be,
shall be made ratably among the Applicable Lenders in accordance with their US Tranche Commitments
or Canadian Tranche Commitments, as the case may be.

     Section 2.07 Optional Prepayments.

          (a) Each Borrower may, at its option, as provided in this Section 2.07, at any time and from
time to time prepay the Loans payable by such Borrower, in whole or in part, upon at least two (2)
Business Days’ prior notice to the Applicable Administrative Agent, specifying (i) the date and
amount of prepayment, and (ii) the respective amounts to be prepaid in respect of such Loans.
Notwithstanding the forgoing, the Canadian Borrower shall not be permitted to prepay any Bankers’
Acceptances or BA Loans at any time. Upon receipt of such prepayment notice, the Applicable
Administrative Agent shall promptly notify each Applicable Lender thereof. The payment amount
specified in such notice shall be due and payable on the date specified. All prepayments pursuant
to this Section 2.07 shall include accrued interest on
the amount prepaid to the date of prepayment and, in the case of prepayments of Eurodollar
Loans, any amounts payable pursuant to Section 2.22. The Loans shall also be subject to prepayment
as provided in Section 2.06, Section 2.08 and Section 9.13.

          (b) Partial optional prepayments pursuant to this Section 2.07 shall be in an aggregate
principal amount of $10,000,000 or any whole multiple of $5,000,000 in excess thereof. All
prepayments of Loans pursuant to this Section 2.07 shall be without the payment by the Applicable
Borrower of any premium or penalty except for amounts payable pursuant to Section 2.22.

     Section 2.08 Mandatory Prepayments. (a) If at any time the total Credit Exposures of the US Tranche Lenders or the Canadian Tranche
Lenders, as the case may be, exceeds the sum of the total US Tranche Commitments or the total
Canadian Tranche Commitments, respectively, the Applicable Borrower shall prepay the Loans (other
than BA Loans) owing by it to such Lenders in an amount equal to such excess. Each prepayment of
Loans pursuant to this Section

27

 

2.08 shall be accompanied by payment of accrued interest on the
amount prepaid to the date of prepayment and, in the case of prepayments of Eurodollar Loans, any
amounts payable pursuant to Section 2.22.

          (b) If, after all Loans (other than BA Loans) have been prepaid pursuant to this Section 2.08,
any such excess remains as a result of LC Exposure, BA Exposure or any combination thereof, the
Applicable Borrowers shall provide cash collateral (i) pursuant to Section 2.05(j)(ii), to cover
any such excess caused by LC Exposure, and/or (ii) pursuant to Section 2.24(j)(ii) to cover any
such excess caused by BA Exposure.

     Section 2.09 Commitment Increases; Adjustment of Tranche Commitments.

          (a) So long as no Default or Event of Default has occurred and is continuing, the US Borrower
may request from time to time, that the aggregate amount of the US Tranche Lenders’ US Tranche
Commitments be increased (each a “US Tranche Commitment Increase”) by delivering a Notice of US
Tranche Commitment Increase; provided, however, that:

               (i) except as provided in Section 2.09(d), no US Tranche Lender’s US Tranche Commitment may
ever be increased without its prior written consent;

               (ii) any Notice of US Tranche Commitment Increase must be given no later than three (3)
Business Days prior to the Revolving Commitment Termination Date;

               (iii) the effective date of any US Tranche Commitment Increase (the “US Tranche Commitment
Increase Effective Date”) shall be no earlier than ten (10) Business Days after receipt by the US
Administrative Agent of such Notice of US Tranche Commitment Increase;

               (iv) the amount of any US Tranche Commitment Increase must be at least $10,000,000;

               (v) after giving effect to any requested US Tranche Commitment Increase, the aggregate amount
of the US Tranche Commitments shall not exceed $1,250,000,000 minus the aggregate amount of the
Canadian Tranche Commitments then in effect;

          (b) On each US Tranche Commitment Increase Effective Date, so long as no Default or Event of
Default has occurred and is continuing and to the extent there are US Tranche Revolving Loans
outstanding as of such date:

               (i) each CI Lender shall, by wire transfer of immediately available funds, deliver to the US
Administrative Agent such CI Lender’s New Funds Amount for the applicable US Tranche Commitment
Increase Effective Date, which amount, for each such CI Lender, shall constitute US Tranche
Revolving Loans made by such CI Lender to the US Borrower pursuant to this Agreement on such US
Tranche Commitment Increase Effective Date; and

28

 

               (ii) the US Administrative Agent shall, by wire transfer of immediately available funds, pay
to each then Reducing Percentage Lender its Reduction Amount for such US Tranche Commitment
Increase Effective Date, which amount, for each such Reducing Percentage Lender, shall constitute a
prepayment by the US Borrower pursuant to Section 2.07, ratably in accordance with the respective
principal amounts thereof, of the principal amounts of all then outstanding US Tranche Revolving
Loans of such Reducing Percentage Lender.

          (c) So long as no Default or Event of Default has occurred and is continuing, each of the
conditions set forth in Section 6.02 are satisfied as of such US Tranche Commitment Increase
Effective Date and no Material Adverse Change shall exist as of such date, each US Tranche
Commitment Increase shall become effective on its US Tranche Commitment Increase Effective Date and
upon such effectiveness (x) the US Administrative Agent shall record in the Register each CI
Lender’s information, if necessary, as provided in the Notice of US Tranche Commitment Increase and
pursuant to an Administrative Questionnaire that shall be completed and delivered by each CI Lender
to the US Administrative Agent on or before the US Tranche Commitment Increase Effective Date and
(y) the US Administrative Agent shall distribute to each Lender (including each CI Lender) a copy
of the Annex I attached to the Notice of US Tranche Commitment Increase relating to such US Tranche
Commitment Increase and (z) each CI Lender identified on the Notice of US Tranche Commitment
Increase for such US Tranche Commitment Increase shall be a “US Lender” for all purposes under this
Agreement.

          (d) So long as no Default or Event of Default has occurred which is continuing, and subject to
all of the terms and conditions hereinafter set forth, at any time during each 12-month period, the
US Borrower may, by providing written notice to the US Administrative Agent (an “Adjustment
Request”), make up to a total of six requests on behalf of all of the Borrowers that the total
Commitments of the Dual Lenders under one of the Tranches be increased on a pro rata basis by an
amount of not less than US$10,000,000 and that simultaneous decreases be made on a pro rata basis
to the unused Commitments of the Dual
Lenders under the other Tranche in amounts that will result in the sum of the total
Commitments of the Dual Lenders remaining unchanged after giving effect to such increases and
decreases; provided, however, that (i) the effect of such changes to the Commitments of the Dual
Lenders shall not result in an increase of the Canadian Tranche Commitments to an amount greater
than US$300,000,000 or result in the reduction of the Canadian Tranche Commitments to an amount
less than US$15,000,000 and (ii) neither the Canadian Tranche Commitments nor the US Tranche
Commitments shall be reduced to an amount less than the Canadian Credit Exposure or the US Credit
Exposure, as the case may be. An Adjustment Request shall set forth (x) the amount of the
requested increase in the Commitments of the Dual Lenders under one of the Tranches (each, a
“Commitment Increase (Reallocation)”), (y) the amount of the requested decreases in the Commitments
of the Dual Lenders under the other Tranche which shall correspond to each Commitment Increase
(Reallocation) (each a “Commitment Decrease (Reallocation)”), and (z) the date on which such
adjustments are requested to become effective (which shall be not less than 5 Business Days or more
than 30 days after the date of such Adjustment Request) (the “Adjustment Effective Date”). On each
Adjustment Effective Date, the US Borrower, on behalf of each of the Borrowers, shall deliver to
the US Administrative Agent a Section 2.09 Certificate. Subject to Section 2.09(g), all such
Adjustment Requests shall become effective on the designated Adjustment Effective Date.

29

 

          (e) If either Administrative Agent receives a Borrowing Request with a Borrowing Date that
coincides with an Adjustment Effective Date set forth in an Adjustment Request, such Borrowing
Request shall be given effect in accordance with all of the terms and conditions set forth herein
after giving effect to the Commitment Increases (Reallocation) and Commitment Decreases
(Reallocation) set forth in such Adjustment Request.

          (f) Commitment Increases (Reallocation), Commitment Decreases (Reallocation) and new
Commitments created pursuant to Section 2.09(d) shall become effective on the Adjustment Effective
Date or US Tranche Commitment Increase Effective Date, as applicable. Subject to Section 2.09(g)
hereof, the US Administrative Agent and the Lenders, including the Dual Lenders, shall have no
discretion in granting requests made under an Adjustment Request.

          (g) Notwithstanding the foregoing, no increase in the Commitments of the Dual Lenders under
either Tranche shall become effective under this Section, unless (i) the US Borrower shall not have
withdrawn its Adjustment Request by written notice to the US Administrative Agent not less than
three Business Days prior to the Adjustment Effective Date, and (ii) on the Adjustment Effective
Date of each Commitment Increase (Reallocation), the US Borrower shall have delivered to the
Administrative Agents a certificate substantially in the form of Exhibit F (each, a “Section 2.09
Certificate”) dated as of such Adjustment Effective Date, executed by a responsible officer of the
US Borrower, on behalf of each of the Borrowers, certifying that, as of such Adjustment Effective
Date, all conditions set forth in Section 6.02 (with respect to such Commitment Increase
(Reallocation) rather than a Borrowing) have been satisfied.

          (h) Notwithstanding the foregoing, adjustments pursuant to Section 2.09(d) shall only be
applicable to the Commitments of the Dual Lenders and shall not affect any outstanding Commitments
of a Lender that is not a Dual Lender.

     Section 2.10 Interest.

          (a) Each US Dollar Eurodollar Loan shall bear interest for each day during each Interest
Period with respect thereto on the unpaid Principal Amount thereof at a rate per annum equal to the
US Dollar LIBO Rate for such Interest Period plus the Eurodollar Margin for such day. Each
Alternate Base Rate Loan shall bear interest on the unpaid Principal Amount thereof at a
fluctuating rate per annum equal to the Alternate Base Rate. Each Canadian Dollar Eurodollar Loan
shall bear interest for each day during each Interest Period with respect thereto on the unpaid
Principal Amount thereof at a rate per annum equal to the Canadian Dollar LIBO Rate for such
Interest Period plus the Eurodollar Margin for such day. Each Canadian Prime Rate Loan shall bear
interest on the unpaid Principal Amount thereof at a fluctuating rate per annum equal to the
Canadian Prime Rate. Each Canadian Base Rate Loan shall bear interest on the unpaid Principal
Amount thereof at a fluctuating rate per annum equal to the Canadian Base Rate. Any overdue
principal of any Loan shall, without limiting the rights of any Lender under ARTICLE VII, bear
interest at a rate per annum which is two percent (2%) above the rate which would otherwise be
applicable to such Loan pursuant to whichever of the four preceding sentences shall apply until
paid in full (as well after as before judgment). Interest shall be

30

 

payable in arrears on each
Interest Payment Date; provided, however, that interest payable on overdue principal shall be
payable on demand.

          (b) Each Borrowing initially shall be of the Type specified in the applicable Borrowing
Request and, in the case of a Eurodollar Loan, shall have an initial Interest Period as specified
in such Borrowing Request. Thereafter, the Applicable Borrower may elect to continue such
Borrowing to a different Type or to continue such Borrowing for an additional Interest Period (and
elect Interest Periods therefor), all as provided in this Section. The Applicable Borrower may
elect different options with respect to different portions of the affected Borrowing, in which case
each such portion shall be allocated ratably among the Applicable Lenders holding the Loans
comprising such Borrowing, and the Loans comprising each such portion shall then and thereafter be
considered a separate Borrowing.

          (c) To make an election pursuant to this Section, the Applicable Borrower shall notify the
Applicable Administrative Agent of such election (the “Interest Election Request”) by telephone by
the time that a Borrowing Request would be required under Section 2.03 if such Borrower were
requesting a Borrowing of the Type resulting from such election to be made on the effective date of
such election. Each such telephonic Interest Election Request shall be irrevocable and shall be
confirmed promptly by hand delivery or telecopy to the Applicable Administrative Agent of a written
Interest Election Request in a form approved by the Applicable Administrative Agent and signed by
the Applicable Borrower.

          (d) Each telephonic and written Interest Election Request shall identify the Applicable
Borrower and specify the following information in compliance with Section 2.03:

               (i) the Borrowing to which such Interest Election Request applies and, if different options
are being elected with respect to different portions thereof, the portions
thereof to be allocated to each resulting Borrowing (in which case the information to be
specified pursuant to clauses (iii) and (iv) below shall be specified for each resulting
Borrowing);

               (ii) the effective date of the election made pursuant to such Interest Election Request, which
shall be a Business Day;

               (iii) whether the resulting Borrowing is to be an Alternate Base Rate Borrowing, a Canadian
Prime Rate Borrowing, a Canadian Base Rate Borrowing or a Eurodollar Borrowing; and

               (iv) if the resulting Borrowing is a Eurodollar Borrowing, whether such Borrowing is to be
comprised of US Dollar Eurodollar Loans or Canadian Dollar Eurodollar Loans, as applicable, and the
Interest Period to be applicable thereto after giving effect to such election, which shall be a
period contemplated by the definition of the term “Interest Period”.

          (e) If any such Interest Election Request requests a Eurodollar Borrowing but does not specify
an Interest Period, then the Applicable Borrower shall be deemed to have selected an Interest
Period of one month’s duration.

31

 

          (f) Promptly following receipt of an Interest Election Request, the Applicable Administrative
Agent shall advise each Applicable Lender of the details thereof and of such Lender’s obligation
with respect to each resulting Borrowing.

          (g) If the Applicable Borrower fails to deliver a timely Interest Election Request with
respect to a Eurodollar Loan prior to the end of the Interest Period applicable thereto, then,
unless such Borrowing is repaid as provided herein, at the end of such Interest Period such
Borrowing shall be continued as an Alternate Base Rate Loan, in the case of Eurodollar Loans made
to the US Borrower, and Canadian Base Rate Loan (if in US Dollars) or a Canadian Prime Rate Loan
(if in Canadian Dollars), in the case of Eurodollar Loans made to the Canadian Borrower.
Notwithstanding any contrary provision hereof, if an Event of Default has occurred and is
continuing and the Applicable Administrative Agent, at the request of the Majority Lenders, so
notifies the Applicable Borrower, then, so long as such Event of Default is continuing (i) no
outstanding Borrowing may be continued as a Eurodollar Loan, and (ii) unless repaid, each
Eurodollar Loan shall be continued as an Alternate Base Rate Loan, in the case of Eurodollar Loans
made to the US Borrower, and a Canadian Base Rate Loan (if in US Dollars) or a Canadian Prime Rate
Loan (if in Canadian Dollars), in the case of Eurodollar Loans made to the Canadian Borrower, at
the end of the Interest Period applicable thereto.

     Section 2.11 Computation of Interest and Fees.

          (a) Interest on Alternate Base Rate Loans, Canadian Prime Rate Loans, Canadian Base Rate Loans
and fees shall be calculated on the basis of a 365- (or 366- as the case may be) day year for the
actual days elapsed. Interest on Eurodollar Loans shall be calculated on the basis of a 360-day
year for the actual days elapsed. The Applicable Administrative Agent shall notify the Applicable
Borrower and the Applicable Lenders of each determination of a US Dollar LIBO Rate or a Canadian
Dollar LIBO Rate. Any change in the interest rate resulting
from a change in the Alternate Base Rate, Canadian Prime Rate or the Canadian Base Rate shall
become effective as of the opening of business on the day on which such change in the applicable
rate shall become effective. The Applicable Administrative Agent shall notify the Applicable
Borrower and the Applicable Lenders of the effective date and the amount of each such change in the
Alternative Base Rate, Canadian Prime Rate and the Canadian Base Rate.

          (b) The Applicable Administrative Agent shall, at the request of the Applicable Borrower,
deliver to such Applicable Borrower a statement showing the computations used by the Applicable
Administrative Agent in determining any interest rate pursuant to Section 2.11(a).

          (c) To the extent permitted by applicable law, any provision of the Interest Act (Canada)
which restricts any rate of interest set forth herein shall be inapplicable to this Agreement and
is hereby waived by the Borrowers.

          (d) The principle of deemed reinvestment shall not apply to the calculation of interest or
payment of fees or other amounts hereunder, and all interest and fees payable by a Borrower to the
Lenders, shall accrue from day to day, computed as described herein in accordance with the “nominal
rate” method of interest calculation.

32

 

          (e) Where, in this Agreement, a rate of interest or fees is to be calculated on the basis of a
360-day year, such rate is, for the purpose of the Interest Act (Canada), equivalent to the said
rate (i) multiplied by the actual number of days in the one year period beginning on the first day
of the period of calculation, and (ii) divided by 360.

     Section 2.12 Funding of Borrowings.

          (a) Each Lender shall make each Loan to be made by it hereunder on the proposed Borrowing Date
thereof by wire transfer of immediately available funds by 11:30 a.m., New York City time, to the
account of the Applicable Administrative Agent most recently designated by it for such purpose by
notice to the Applicable Lenders, which Loan shall be in the appropriate currency (based on the
relevant Borrowing Request). The Applicable Administrative Agent will make such Loans available to
the Requesting Borrower by promptly crediting the amounts so received, in like funds, to an account
of such Requesting Borrower designated by such Requesting Borrower in the applicable Borrowing
Request; provided that Alternate Base Rate Loans, Canadian Base Rate Loans or Canadian Prime Rate
Loans made to finance the reimbursement of an LC Disbursement as provided in Section 2.05(e) shall
be remitted by the Applicable Administrative Agent to the Issuing Bank; and provided further that
any Canadian Prime Rate Loan or any Canadian Base Rate Loan made to refinance a BA Loan pursuant to
Section 2.24 shall be remitted by the Canadian Administrative Agent to the applicable Accepting
Lender.

          (b) Unless the Applicable Administrative Agent shall have received notice from an Applicable
Lender prior to the proposed date of any Borrowing that such Lender will not make available to the
Applicable Administrative Agent such Lender’s share of such Borrowing, the Applicable
Administrative Agent may assume that such Lender has made such share
available on such date in accordance with Section 2.12(a) and may, in reliance upon such
assumption, make available to the Requesting Borrower a corresponding amount. In such event, if an
Applicable Lender has not in fact made its share of the applicable Borrowing available to the
Applicable Administrative Agent, then each such Lender and the Requesting Borrower severally agree
to pay to the Applicable Administrative Agent forthwith on demand such corresponding amount with
interest thereon, for each day from and including the date such amount is made available to the
Requesting Borrower to but excluding the date of payment to the Applicable Administrative Agent, at
(i) in the case of such Lender, the greater of the cost incurred by the Applicable Administrative
Agent for making such Lender’s share of such Borrowing and a rate determined by the Applicable
Administrative Agent in accordance with banking industry rules on interbank compensation, or (ii)
in the case of a Requesting Borrower, the interest rate applicable to Alternate Base Rate Loans or
Canadian Base Rate Loans, as applicable. If such Lender pays such amount to the Applicable
Administrative Agent, then such amount shall constitute such Lender’s Loan included in such
Borrowing.

          (c) Borrowings or continuations of Loans, and prepayments of Loans or different currencies at
the same time hereunder shall be deemed to be separate Borrowings, continuations and prepayments,
respectively, one for each currency.

33

 

     Section 2.13 Pro Rata Treatment and Payments.

          (a) Each Borrowing by an Applicable Borrower from the Applicable Lenders, each payment
(including each prepayment) by an Applicable Borrower on account of the principal of and interest
on the Loans and on account of any fees hereunder, any reimbursement of LC Disbursements, and any
reduction of the Commitments of the Lenders hereunder shall be made pro rata according to the US
Tranche Commitments or the Canadian Tranche Commitments, as applicable, except that (i) payments or
prepayments, and offsets against or reductions from the amount of payments and prepayments, in each
case, specifically for the account of a particular Lender under the terms of Section 2.04, Section
2.09(b), Section 2.14, Section 2.15, Section 2.16, Section 2.22, Section 9.03 or Section 9.13 shall
be made for the account of such Lender, (ii) payments of interest on BA Loans shall be made for the
account of the Lenders making such Loans (it being recognized that interest on such Loans are
payable in arrears while Stamping Fees on the Bankers’ Acceptance for which such BA Loan is a
substitute are payable in advance, and Bankers’ Acceptances are discounted on the applicable
Acceptance Date), and (iii) if any Lender shall become a Defaulting Lender, from and after the date
upon which such Lender shall have become a Defaulting Lender, any payment made on account of
principal of or interest on the Loans shall be applied, first for the account of the Lenders other
than the Defaulting Lender, pro rata according to the US Tranche Commitments or the Canadian
Tranche Commitments, as applicable, of such Lenders, until the principal of and interest on the
Loans of such Lenders shall have been paid in full and, second for the account of such Defaulting
Lender, provided that the application of such payments in accordance with this clause (iii) shall
not constitute an Event of Default or a Default, and no payment of principal of or interest on the
Loans of such Defaulting Lender shall be considered to be overdue for purposes of Section 2.10(a),
if, had such payments been applied without regard to this clause (iii), no such Event of Default or
Default would have occurred and no such payment of principal of or interest
on the Loans of such Defaulting Lender would have been overdue. All payments (including
prepayments) to be made by a Borrower on account of principal, interest, reimbursement of LC
Disbursements and fees shall be made in immediately available funds without setoff or counterclaim
and shall be made to the Applicable Administrative Agent on behalf of the Applicable Lenders at the
Applicable Administrative Agent’s office as notified to the US Borrower from time to time at least
five (5) Business Days before any change in such office. On the date of this Agreement, the office
of the Applicable Administrative Agent is located (i) in the case of Canadian Prime Rate Loans,
Canadian Base Rate Loans, and fees, for the account of the Domestic Lending Offices of the Lenders,
(A) with respect to the Canadian Administrative Agent, at 200 Bay Street, Royal Bank Plaza, Floor
18, Toronto, M5J 2J2, Canada, Attention: Amanda Staff (Telecopy No. 416-981-9128), with a copy to

(B) in the case of Alternate Base Rate Loans and Eurodollar Loans, for the account of the
Eurodollar Lending Offices or Domestic Lending Offices, as the case may be, of the Lenders which
shall then be maintaining Eurodollar Loans, in each case in US Dollars (or Canadian Dollars in the
case of payments relating to Loans, Letters of Credit, Bankers’ Acceptances or other Credit
Exposure denominated in Canadian
 Dollars), with respect to the US Administrative Agent, at
JPMorgan Chase Bank, Loan and Agency Services Group, 1111 Fannin, 10th Floor, Houston, Texas 77002,
Attention of Karla Contreras, Phone No.: (713) 750-2355, Facsimile No.: (713) 427-6307 at or before
12:00 noon (New York City time), and (ii) JPMorgan Chase Bank, Loan and Agency

34

 

Services Group, 1111
Fannin, 10th Floor, Houston, Texas 77002, Attention of Karla Contreras, Phone No.: (713) 750-2355,
Facsimile No.: (713) 427-6307 at or before 12:00 noon (New York City time). The Applicable
Administrative Agent shall distribute such payments to the Lenders promptly upon receipt in like
funds as received. Reimbursement of all LC Disbursements shall be made as required by Section
2.05(e).

          (b) If any payment hereunder (other than payments on the Eurodollar Loans) becomes due and
payable on a day other than a Business Day, such payment shall be extended to the next succeeding
Business Day, and with respect to payments of principal, interest thereon shall be payable at the
then applicable rate during such extension. If any payment on a Eurodollar Loan becomes due and
payable on a day other than a Business Day, the maturity thereof shall be extended to the next
succeeding Business Day unless the result of such extension would be to extend such payment into
another calendar month in which event such payment shall be made on the immediately preceding
Business Day.

          (c) Except as provided in Section 2.04(e), Section 2.09(b), Section 2.09(d), Section 2.14,
Section 2.15, Section 2.16, Section 2.22, Section 9.03, Section 9.13, and this Section 2.13, if any
Lender shall, by exercising any right of set-off or counterclaim or otherwise, obtain payment in
respect of any principal of or interest on any of the Loans or participations in LC Disbursements
under either Tranche resulting in such Lender receiving payment of a greater proportion of the
aggregate amount of its Loans and participations in LC Disbursements and accrued interest thereon
under such Tranche than the proportion received by any other Lender with respect to the US Tranche
or the Canadian Tranche, as the case may be, then the Lender receiving such greater proportion
shall purchase (for cash at face value) participations in the Loans and participations in LC
Disbursements with respect to the US Tranche or the Canadian Tranche, as the case may be, of other
Lenders with respect to the US Tranche or the Canadian
Tranche, as the case may be, to the extent necessary so that the benefit of all such payments
shall be shared by such Lenders ratably in accordance with the aggregate amount of principal of and
accrued interest on their respective Loans and participations in LC Disbursements; provided that
(i) if any such participations are purchased and all or any portion of the payment giving rise
thereto is recovered, such participations shall be rescinded and the purchase price restored to
the extent of such recovery, without interest, and (ii) the provisions of this paragraph shall not
be construed to apply to any payment made by a Borrower pursuant to and in accordance with the
express terms of this Agreement or any payment obtained by a Lender as consideration for the
assignment of or sale of a participation in any of its Loans or participations in LC Disbursements
to any assignee or participant, other than to a Borrower or any Subsidiary or Affiliate thereof (as
to which the provisions of this paragraph shall apply). The Borrowers consent to the foregoing and
agree, to the extent they may effectively do so under applicable law, that any Lender acquiring a
participation pursuant to the foregoing arrangements may exercise against the Applicable Borrower
rights of set-off and counterclaim with respect to such participation as fully as if such Lender
were a direct creditor of such Borrower in the amount of such participation.

          (d) Unless the Applicable Administrative Agent shall have received notice from the Applicable
Borrower prior to the date on which any payment is due to the Applicable Administrative Agent for
the account of the Applicable Lenders or an Issuing Bank hereunder that the Applicable Borrower
will not make such payment, the Applicable Administrative Agent may assume that the Applicable
Borrower has made such payment on such date in accordance

35

 

herewith and may, in reliance upon such
assumption, distribute to the Applicable Lenders or any Issuing Bank, as the case may be, the
amount due. In such event, if the Applicable Borrower has not in fact made such payment, then each
of the Applicable Lenders or an Issuing Bank, as the case may be, severally agrees to repay to the
Applicable Administrative Agent forthwith on demand the amount so distributed to such Lender or
such Issuing Bank with interest thereon, for each day from and including the date such amount is
distributed to it to but excluding the date of payment to the Applicable Administrative Agent, at
the greater of the cost incurred by the Applicable Administrative Agent for making such distributed
amount and a rate determined by the Applicable Administrative Agent in accordance with banking
industry rules on interbank compensation.

          (e) If any Lender shall fail to make any payment required to be made by it pursuant to Section
2.05(d), Section 2.05(e), Section 2.09(b), Section 2.12(b) or Section 2.13(d), then the Applicable
Administrative Agent may, in its discretion (notwithstanding any contrary provision hereof), apply
any amounts thereafter received by such Administrative Agent for the account of such Lender to
satisfy such Lender’s obligations under such Sections until all such unsatisfied obligations are
fully paid.

     Section 2.14 Increased Cost of Loans.

          (a) If any change in any applicable law, treaty or governmental regulation after the date of
this Agreement, or in the interpretation or application thereof after the date of this Agreement,
or compliance by any Lender or any Issuing Bank with any request or directive
(whether or not having the force of law) from any central bank or other Governmental Authority
made or issued after the date of this Agreement, which:

               (i) does or shall impose, modify or hold applicable any reserve, special deposit, compulsory
loan or similar requirement against assets held by, or deposits or other liabilities in or for the
account of, advances or loans by, or other credit extended by, or any other acquisition of funds
by, any office of such Lender or such Issuing Bank; or

               (ii) does or shall impose on such Lender or such Issuing Bank or the London interbank market
any other condition affecting this Agreement, any Note or the Eurodollar Loans, or any Letter of
Credit or participation therein;

and the result of any of the foregoing is to increase the cost to such Lender of making, continuing
or maintaining any Eurodollar Loan or BA Loan or accepting any Bankers’ Acceptance (or of
maintaining its obligation to make any such Loan or BA Loan or Bankers’ Acceptance) or to increase
the cost to such Lender or such Issuing Bank of participating in, issuing or maintaining any Letter
of Credit or BA Loan or Bankers’ Acceptance, or to reduce any amount received or receivable by such
Lender or such Issuing Bank hereunder or under any Note (whether of principal, interest, or
otherwise), then, in any such case, the Applicable Borrower shall pay such Lender or such Issuing
Bank, as the case may be, upon written demand being made to the Applicable Borrower by such Lender
or such Issuing Bank, as the case may be, such additional amount or amounts which will compensate
such Lender or such Issuing Bank, as the case may be, for such amounts as such Lender or such
Issuing Bank reasonably deems to be material with respect to this Agreement, the Notes, the Letters
of Credit, or the Loans hereunder, provided,

36

 

however, that if all or any such additional cost would
not have been payable, or such reduction would not have occurred, but for such Lender’s or such
Issuing Bank’s decision to designate a new Eurodollar Lending Office or Domestic Lending Office or
refusal to change to another Eurodollar Lending Office or Domestic Lending Office as provided
below, the Applicable Borrower shall have no obligation under this Section 2.14 to compensate such
Lender or such Issuing Bank for such amount. Such demand shall be accompanied by a certificate of
a duly authorized officer of such Lender or such Issuing Bank setting forth the amount of such
payment and the basis therefor. Each Applicable Lender or an Issuing Bank shall also give written
notice to the Applicable Borrower and the Applicable Administrative Agent of any event occurring
after the date of this Agreement which would entitle such Lender or such Issuing Bank to
compensation pursuant to this Section 2.14 as promptly as practicable after it obtains knowledge
thereof and determines to request such compensation and will designate a different Eurodollar
Lending Office or a Domestic Lending Office 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. Notwithstanding the foregoing, in the event that any Lender or
Issuing Bank shall demand payment pursuant to this Section 2.14, the Applicable Borrower may, upon
at least two (2) Business Days’ notice to the Applicable Administrative Agent and such Lender,
continue in whole (but not in part) the Eurodollar Loans of such Lender into Alternate Base Rate
Loans, in the case of Eurodollar Loans made to the US Borrower, or Canadian Prime Rate Loans (if in
Canadian Dollars) or Canadian Base Rate Loans (if in US Dollars), in the case of Eurodollar Loans
made to the Canadian Borrower, without regard to the requirements of Section 2.10.

          (b) If any Lender or any Issuing Bank shall have reasonably determined that the adoption after
the date of this Agreement of any law, rule or regulation regarding capital adequacy, or any change
therein or in the interpretation or application thereof after the date of this Agreement or
compliance by any Lender or any Issuing Bank with any request or directive regarding capital
adequacy (whether or not having the force of law) from any central bank or governmental authority
made or issued after the date of this Agreement, does or shall have the effect of reducing the rate
of return on such Lender’s or such Issuing Bank’s capital, or in the capital of such Lender’s or
Issuing Bank’s holding company, if any, as a consequence of its obligations hereunder to a level
below that which such Lender or such Issuing Bank, or such Lender’s or such Issuing Bank’s holding
company, could have achieved but for such adoption, change or compliance (taking into consideration
such Lender’s or such Issuing Bank’s policies and the policies of such Lender’s or such Issuing
Bank’s holding company with respect to capital adequacy) by an amount reasonably deemed by such
Lender to be material, then from time to time, after submission by such Lender or such Issuing Bank
to the Applicable Borrower (with a copy to the Applicable Administrative Agent) of a written
request therefor, the Applicable Borrower shall pay to such Lender or such Issuing Bank such
additional amount or amounts as will compensate such Lender or such Issuing Bank for such reduction
from and after such date the Borrower receives the request; provided, however, that the foregoing
shall not apply to any capital adequacy requirement imposed solely by reason of any business
combination effected after the date hereof.

          (c) A certificate of a Lender or an Issuing Bank setting forth the amount or amounts necessary
to compensate such Lender or such Issuing Bank or its holding company, as the case may be, as
specified in paragraph (a) or (b) of this Section 2.14 shall be delivered to the

37

 

Applicable
Borrower and shall be prima facie evidence of the amount of such payment. The Applicable Borrower
shall pay such Lender or such Issuing Bank, as the case may be, the amount shown as due on any such
certificate within ten (10) days after receipt thereof.

          (d) Failure or delay on the part of any Lender or any Issuing Bank to demand compensation
pursuant to this Section 2.14 shall not constitute a waiver of such Lender’s or such Issuing Bank’s
right to demand such compensation; provided that the Applicable Borrower shall not be required to
compensate a Lender or an Issuing Bank pursuant to this Section 2.14 for any increased costs or
reductions incurred more than 270 days prior to the date that such Lender or such Issuing Bank, as
the case may be, notifies the Applicable Borrower of the change in law giving rise to such
increased costs or reductions and of such Lender’s or such Issuing Bank’s intention to claim
compensation therefor; provided further that, if the change in law giving rise to such increased
costs or reductions is retroactive, then the 270-day period referred to above shall be extended to
include the period of retroactive effect thereof.

     Section 2.15 Illegality. Notwithstanding anything herein contained, if any Lender shall make a good faith determination
that a change in any applicable law or regulation after the date of this Agreement or in the
interpretation thereof after the date of this Agreement by any authority charged with the
administration thereof shall make it unlawful for such Lender to give effect to its obligations to
make, continue or maintain its Eurodollar Loans under this Agreement, the obligation of such Lender
to make, continue or maintain Eurodollar Loans hereunder shall be suspended for the
duration of such illegality. Such Lender, by written notice to the Administrative Agents, and to
the Borrowers, shall declare that such Lender’s obligation to make Eurodollar Loans and to,
continue and maintain Eurodollar Loans shall be suspended, and the Applicable Borrower, on the last
day of the then current Interest Period applicable to such Eurodollar Loans or portion thereof or,
if such Lender so requests, on such earlier date as may be required by relevant law, shall continue
such Eurodollar Loans or portion thereof as Alternate Base Rate Loans, in the case of Eurodollar
Loans made to the US Borrower, and Canadian Base Rate Loans (if in US Dollars) or as Canadian Prime
Rate Loans (if in Canadian Dollars) in the case of Eurodollar Loans made to the Canadian Borrower,
without regard to the requirements of Section 2.10. If and when such illegality ceases to exist,
such suspension shall cease and such Lender shall notify the Applicable Borrower and the
Administrative Agents thereof and any Loans previously continued from Eurodollar Loans to Canadian
Base Rate Loans or Canadian Prime Rate Loans pursuant to this Section 2.15 shall be continued as
Loans of Types corresponding to the Loans maintained by the other Applicable Lenders on the last
day of the Interest Period of the corresponding Eurodollar Loans of such other Lenders.

     Section 2.16 Taxes.

          (a) Any and all payments by or on account of any obligation of a Borrower under each Loan
Document shall be made free and clear of and without deduction or withholding for any Indemnified
Taxes or Other Taxes; provided that if such Borrower shall be required to deduct or withhold any
Indemnified Taxes or Other Taxes from such payments, then (i) the sum payable shall be increased as
necessary so that after making all required deductions or withholding (including deductions or
withholding applicable to additional sums payable under this Section), the US Administrative Agent,
the Canadian Administrative Agent, any US Tranche Lender, any Canadian Tranche Lender or any
Issuing Bank (as the case may be) receives an

38

 

amount equal to the sum it would have received had no
such deductions or withholding been made, (ii) such Borrower shall make such deductions or
withholding, and (iii) such Borrower shall pay the full amount deducted or withheld to the relevant
Governmental Authority in accordance with applicable law.

          (b) In addition, the Borrowers shall pay any Other Taxes to the relevant Governmental
Authority in accordance with applicable law.

          (c) Each Borrower shall indemnify the US Administrative Agent, the Canadian Administrative
Agent, each US Tranche Lender and Canadian Tranche Lender and each Issuing Bank, within ten (10)
days after written demand therefor, for the full amount of any Indemnified Taxes or Other Taxes
paid by the US Administrative Agent, the Canadian Administrative Agent, such US Tranche Lender,
Canadian Tranche Lender or such Issuing Bank, as the case may be, on or with respect to any payment
by or on account of any obligation of such Borrower under each Loan Document (including Indemnified
Taxes or Other Taxes imposed or asserted on or attributable to amounts payable under this Section)
and any penalties, interest and reasonable expenses arising therefrom or with respect thereto,
whether or not such Indemnified Taxes or Other Taxes were correctly or legally imposed or asserted
by the relevant Governmental Authority. A certificate as to the amount of such payment or
liability delivered to a Borrower by a Lender or an Issuing Bank, or by the US Administrative Agent or Canadian
Administrative Agent on its own behalf or on behalf of a Lender or an Issuing Bank, shall be
conclusive absent manifest error.

          (d) As soon as practicable after any payment of Indemnified Taxes or Other Taxes by any
Borrower to a Governmental Authority, such Borrower shall deliver to the US Administrative Agent
and the Canadian Administrative Agent the original or a certified copy of a receipt issued by such
Governmental Authority evidencing such payment, a copy of the return reporting such payment or
other evidence of such payment reasonably satisfactory to the US Administrative Agent and, if
relating to the Canadian Tranche, the Canadian Administrative Agent.

          (e) Any Foreign Lender that is entitled to an exemption from or reduction of withholding tax
under the law of the jurisdiction in which the US Borrower is located, or any treaty to which such
jurisdiction is a party, with respect to payments under this Agreement shall deliver to the US
Borrower (with a copy to the US Administrative Agent), at the time or times prescribed by
applicable law, such properly completed and executed documentation prescribed by applicable law or
reasonably requested by the US Borrower as will permit such payments to be made without withholding
or at a reduced rate.

          (f) For any period during which a Foreign Lender has failed to provide the US Borrower with
the appropriate documentation as required by Section 2.16(e), the US Borrower shall not be
obligated to pay, and such Foreign Lender shall not be entitled to secure additional amounts under
this Section 2.16 with respect to Indemnified Taxes imposed by a Governmental Authority to the
extent that such additional amounts would not have arisen but for such failure of such Foreign
Lender.

39

 

          (g) If the US Administrative Agent, the Canadian Administrative Agent, or a Lender determines,
in its sole discretion, that it has received a refund of any Taxes or Other Taxes as to which it
has been indemnified by a Borrower or with respect to which a Borrower has paid additional amounts
pursuant to this Section 2.16, it shall pay over such refund to such Borrower (but only to the
extent of indemnity payments made, or additional amounts paid, by such Borrower under this Section
2.16 with respect to the Taxes or Other Taxes giving rise to such refund), net of all out-of-pocket
expenses of the US Administrative Agent, the Canadian Administrative Agent or such Lender and
without interest (other than any interest paid by the relevant Governmental Authority with respect
to such refund); provided, however, that such Borrower, upon the request of the US Administrative
Agent, the Canadian Administrative Agent or such Lender, agrees to forthwith repay the amount paid
over to such Borrower (plus any penalties, interest or other charges imposed by the relevant
Governmental Authority) to the US Administrative Agent, the Canadian Administrative Agent, or such
Lender in the event the US Administrative Agent, the Canadian Administrative Agent, or such Lender
is required to repay such refund to such Governmental Authority. Nothing contained in this Section
2.16 shall require the US Administrative Agent, the Canadian Administrative Agent, or any Lender to
make available its tax returns (or any other information relating to its taxes which it deems
confidential) to any Borrower or any other Person.

     Section 2.17 Substitute Loan Basis. In the event that prior to the commencement of any Interest Period for any Eurodollar Borrowing
the Majority Lenders shall reasonably determine (which determination shall be final and conclusive
and binding upon the Borrowers) that (a) by reason of changes affecting the London Interbank
Eurodollar Market, adequate and fair means do not exist for ascertaining the US Dollar LIBO Rate or
the Canadian Dollar LIBO Rate for such requested Interest Period, or (b) the US Dollar LIBO Rate or
Canadian LIBO Rate will not adequately and fairly reflect the cost to such Lenders of making or
maintaining their Loans included in such Borrowing for such Interest Period then, and in any such
event, the Applicable Administrative Agent shall forthwith give notice to the Applicable Borrower
and, (i) unless, on the date upon which such Eurodollar Loans were to be made, such Borrower
notifies the Applicable Administrative Agent that it elects not to borrow on such date, any
Eurodollar Loans requested to be made on the first day of such Interest Period shall be made as
Alternate Base Rate Loans, in the case of the US Borrower, and as Canadian Base Rate Loans, in the
case of the Canadian Borrower, (ii) any Loans that were to have been, on the first day of such
Interest Period, continued as Eurodollar Loans, shall be continued as Alternate Base Rate Loans, in
the case of the US Borrower, and as Canadian Base Rate Loans (if in US Dollars) or Canadian Prime
Rate Loans (if in Canadian Dollars), in the case of the Canadian Borrower, on the date upon which
such Loans were to have been continued, and (iii) any outstanding Eurodollar Loans shall be
continued, on the last day of the Interest Period applicable thereto, as Alternate Base Rate Loans,
in the case of the US Borrower, and as Canadian Base Rate Loans, in the case of the Canadian
Borrower, on the date upon which such Loans are to be continued. If any Lender is required to make
a Canadian Prime Rate Loan or continue a Loan as a Canadian Prime Rate Loan pursuant to subsections
(i) through (iii) above, and such Lender is, for any reason, unable to access Canadian Dollars to
fund such Canadian Prime Rate Loan, then such Lender shall, instead of making or continuing such
Canadian Prime Rate Loan (as the case may be) pursuant to subsections (i) through (iii) above, make
or continue (as the case may be) such Loan as a Canadian Base Rate Loan. The Applicable
Administrative Agent shall give written notice to the Applicable Borrower of any event occurring
after the giving of such notice which permits an

40

 

adequate and fair means of ascertaining the US
Dollar LIBO Rate and the Canadian Dollar LIBO Rate and until such notice by the Applicable
Administrative Agent, no further Eurodollar Loans shall be made or continued as such, nor shall the
Borrower have the right to continue as Eurodollar Loans.

     Section 2.18 Certain Prepayments or Continuations. If the Eurodollar Loans of any Applicable Lender are prepaid or continued as Alternate Base Rate
Loans, Canadian Prime Rate Loans or Canadian Base Rate Loans pursuant to Section 2.14 or Section
2.15 (such Eurodollar Loans being herein called “Affected Loans”), unless and until such Lender
gives written notice that the circumstances which gave rise to such prepayment or continuation no
longer exist (which such Lender agrees to do promptly upon such circumstances ceasing to exist)
such Lender shall not make further Affected Loans and all Loans which would otherwise be made by
such Lender as, or continued by such Lender into, Affected Loans shall be made instead as, or
continued as Alternate Base Rate Loans, Canadian Base Rate Loans (if in US Dollars) or Canadian
Prime Rate Loans (if in Canadian Dollars), as the case may be (on which interest and principal
shall be payable simultaneously with the related Affected Loans of the other Applicable Lenders).

     Section 2.19 Certain Notices. Notices by a Borrower under each of Section 2.03, Section 2.05, Section 2.06, Section 2.07,
Section 2.14, Section 2.17, and Section 2.10 and under the definition of “Interest Period” in
Section 1.01 (a) shall be given in writing, by telecopy or by telephone (confirmed promptly in
writing), and (b) shall be effective only if received by the Applicable Administrative Agent and,
in the case of Section 2.14, the Lender involved, not later than 10:30 A.M. (New York City time) on
the day specified in the respective Section or definition as the latest day such notice may be
given. Notices by the Applicable Borrower under each of Section 2.03, Section 2.05, Section 2.06,
Section 2.07, Section 2.14, Section 2.17, and Section 2.10 shall be irrevocable.

     Section 2.20 Reserved.

     Section 2.21 Minimum Amounts of Eurodollar Borrowings. All Borrowings and
continuations of Loans hereunder and all selections of Interest Periods
hereunder shall be in such amounts and be made pursuant to such elections so that, after giving
effect thereto, the aggregate Principal Amount of the Loans comprising each Eurodollar Borrowing
shall be equal to $10,000,000 or a whole multiple of $5,000,000 in excess thereof.

     Section 2.22 Break Funding Payments. In the event of (a) the payment of any Principal Amount of any Eurodollar Loan or BA Loan or
Bankers’ Acceptance other than on the last day of an Interest Period applicable thereto (including
as a result of an Event of Default), (b) the continuation of any Eurodollar Loan or BA Loan or
Bankers’ Acceptance other than on the last day of the Interest Period applicable thereto, (c) the
failure to borrow, continue or prepay any Loan on the date specified in any notice delivered
pursuant hereto, (d) the assignment of any Eurodollar Loan or BA Loan or Bankers’ Acceptance other
than on the last day of the Interest Period applicable thereto as a result of a request by the
Applicable Borrower, then, in any such event, such Borrower shall compensate each Applicable Lender
or each Issuing Bank for the loss, cost and expense attributable to such event. In the case of a
Eurodollar Loan, such loss, cost or expense to any Applicable Lender shall be deemed to include an
amount determined by

41

 

such Lender to be the excess, if any, of (i) the amount of interest which
would have accrued on the Principal Amount of such Loan had such event not occurred, at the US
Dollar LIBO Rate or Canadian Dollar LIBO rate, as applicable (in the case of a Eurodollar Loan)
that would have been applicable to such Loan, for the period from the date of such event to the
last day of the then current Interest Period therefor (or, in the case of a failure to borrow or
continue, for the period that would have been the Interest Period for such Loan), over (ii) the
amount of interest which would accrue on such Principal Amount for such period at the interest rate
which such Lender would bid were it to bid, at the commencement of such period, for dollar deposits
of a comparable amount and period from other banks in the Eurodollar market. A certificate of any
such Lender setting forth any amount or amounts that such Lender is entitled to receive pursuant to
this Section shall be delivered to the Applicable Borrower and the Administrative Agents and shall
be conclusive absent manifest error. The Applicable Borrower shall pay such Lender the amount
shown as due on any such certificate within ten (10) days after receipt thereof. Notwithstanding
anything to the contrary contained herein, (y) no Lender shall be entitled to receive any amount or
amounts pursuant to this Section if such amount or amounts are attributable solely to the merger or other consolidation of such
Lender with another Lender and (z) nothing in this Section 2.22 shall be construed as giving rise
to any right of the Canadian Borrower to prepay any Bankers’ Acceptance or BA Loans.

     Section 2.23 Currency Conversion and Currency Indemnity.

          (a) Each Borrower shall make payment relative to any obligation in the currency (the “Agreed
Currency”) in which the obligation was effected. If any payment is received on account of any
obligation in any currency (the “Other Currency”) other than the Agreed Currency (whether
voluntarily or pursuant to an order or judgment or the enforcement thereof or the realization of
any collateral or the liquidation of a Borrower or otherwise), such payment shall constitute a
discharge of the liability of such Borrower hereunder and under the other Loan Documents in respect
of such obligation only to the extent of the amount of the Agreed Currency which the Applicable
Lender or Applicable Administrative Agent, as the case may be, is able to purchase with the amount
of the Other Currency received by it on the Business Day next following such receipt in accordance
with its normal procedures and after deducting any premium and costs of exchange.

          (b) If, for the purpose of obtaining or enforcing judgment in any court in any jurisdiction,
it becomes necessary to convert into a particular currency (the “Judgment Currency”) any amount due
in the Agreed Currency then the conversion shall be made on the basis of the rate of exchange
prevailing on the next Business Day following the date such judgment is given and in any event the
Applicable Borrower shall be obligated to pay the Applicable Administrative Agent and the
Applicable Lenders any deficiency in accordance with Section 2.23(c). For the foregoing purposes
“rate of exchange” means the rate at which the Applicable Lender or Applicable Administrative
Agent, as the case may be, in accordance with its normal banking procedures is able on the relevant
date to purchase the Agreed Currency with the Judgment Currency after deducting any premium and
costs of exchange.

          (c) To the fullest extent permitted by applicable law, if (i) any Lender or either
Administrative Agent receives any payment or payments on account of the liability of a Borrower
hereunder pursuant to any judgment or order in any Other Currency, and (ii) the

42

 

amount of the
Agreed Currency which the Applicable Lender or Applicable Administrative Agent, as applicable, is
able to purchase on the Business Day next following such receipt with the proceeds of such payment
or payments in accordance with its normal procedures and after deducting any premiums and costs of
exchange is less than the amount of the Agreed Currency due in respect of such liability
immediately prior to such judgment or order, then such Borrower on demand shall, and such Borrower
hereby agrees to, indemnify the Applicable Lender and the Applicable Administrative Agent from and
against any loss, cost or expense arising out of or in connection with such deficiency.

          (d) To the fullest extent permitted by applicable law, the agreement of indemnity provided for
in Section 2.23(c) shall constitute an obligation separate and independent from all other
obligations contained in this Agreement, shall give rise to a separate and independent cause of
action, shall apply irrespective of any indulgence granted by the Lenders or
Administrative Agents or any of them from time to time, and shall continue in full force and
effect notwithstanding any judgment or order for a liquidated sum in respect of an amount due
hereunder or under any judgment or order.

     Section 2.24 Bankers’ Acceptances.

          (a) Subject to the terms and conditions of this Agreement, the Canadian Tranche Commitments
may be utilized, upon the request of the Canadian Borrower, in addition to the Loans provided for
by Section 2.01 and the issuance of Letters of Credit provided for by Section 2.05, for the
acceptance by the Canadian Tranche Lenders of Bankers’ Acceptances issued by the Canadian Borrower,
provided that (i) in no event shall the Equivalent Amount in US Dollars of the aggregate amount of
all Bankers’ Acceptance Liabilities together with the Equivalent Amount in US Dollars of the
aggregate principal amount of the other Loans (excluding BA Loans) and the aggregate amount of all
Canadian LC Exposure exceed the aggregate amount of the Canadian Tranche Commitments of the
Canadian Tranche Lenders, (ii) all Bankers’ Acceptances shall have maturities which are an integral
multiple of thirty (30) days, and are not less than thirty (30) days or more than 180 days, from
the Acceptance Date (and shall in no event mature on a date after the Revolving Commitment
Termination Date), and (iii) in no event shall the amount of any Borrowing by way of Bankers’
Acceptance be less than C$1,000,000 and other than in multiples of C$100,000 for any amounts in
excess thereof. Whenever the Canadian Borrower is required to furnish a notice to the Canadian
Administrative Agent pursuant to the following additional provisions of this Section, it shall give
a copy of such notice to the US Administrative Agent.

          (b) In order to facilitate and expedite the issuance and acceptance of Bankers’ Acceptances
hereunder, the Canadian Borrower agrees to the terms and conditions of the Power of Attorney with
respect to the Bankers’ Acceptance attached hereto as Exhibit C.

          (c) When the Canadian Borrower wishes to make a Borrowing by way of Bankers’ Acceptances, the
Canadian Borrower shall give the Canadian Administrative Agent and the US Administrative Agent
prior written notice with respect to the issuance of the Bankers’ Acceptances (such written notice
a “Bankers’ Acceptance Request”) by not later than 1:00 p.m., Toronto time, two (2) Business Days’
prior to the Acceptance Date. Each Bankers’ Acceptance Request shall be irrevocable and binding on
the Canadian Borrower. The Canadian

43

 

Borrower shall indemnify each Canadian Tranche Lender against
any loss or expense incurred by such Lender as a result of any failure by the Canadian Borrower to
fulfill or honor before the date specified as the Acceptance Date, the applicable conditions set
forth in ARTICLE VI, if, as a result of such failure the requested Bankers’ Acceptance is not made
on such date. Unless otherwise agreed among the Canadian Administrative Agent, the US
Administrative Agent, and the Canadian Tranche Lenders, the aggregate amount of all Bankers’
Acceptances issued on any Acceptance Date hereunder shall be accepted pro rata by all Canadian
Tranche Lenders relative to their respective Canadian Tranche Percentage, rounded, upwards or
downwards, as the case may be, to the nearest C$100,000. Upon receipt of a Bankers’ Acceptance
Request, the Canadian Administrative Agent shall advise each Canadian Tranche Lender of the
contents thereof. Upon the acceptance of a Bankers’ Acceptance by a Canadian Tranche Lender, such
Lender shall purchase such Bankers’ Acceptance from the Canadian Borrower and pay to the
Canadian Administrative Agent, for the account of the Canadian Borrower, the amount of the BA Net
Proceeds in respect of such Bankers’ Acceptance.

          (d) On each day during the period commencing with the issuance by the Canadian Borrower of any
Bankers’ Acceptance and until such Bankers’ Acceptance Liability shall have been paid by the
Canadian Borrower, the Canadian Tranche Commitment of each Accepting Lender that is able to extend
credit by way of Bankers’ Acceptances shall be deemed to be utilized for all purposes of this
Agreement in an amount equal to the Principal Amount of such Bankers’ Acceptance. The Canadian
Tranche Commitment of any Canadian Tranche Lender providing a BA Loan rather than Bankers’
Acceptances shall be deemed utilized during this period in an amount equal to its Canadian Tranche
Percentage of the total amount of Bankers’ Acceptances and BA Loans in each Bankers’ Acceptance
Request.

          (e) The Canadian Borrower agrees to pay on the BA Maturity Date for each Bankers’ Acceptance,
to the Canadian Administrative Agent for account of each Accepting Lender, an amount equal to the
Bankers’ Acceptance Liability of the Canadian Borrower for such Bankers’ Acceptance. The Canadian
Borrower hereby waives presentment for payment of Bankers’ Acceptances by each Accepting Lender and
any defense to payment of amounts due to an Accepting Lender in respect of a Bankers’ Acceptance
which might exist by reason of such Bankers’ Acceptance being held at maturity by the Accepting
Lender which accepted it and agree not to claim from such Lenders any days of grace for the payment
at maturity of Bankers’ Acceptances.

          (f) If the Canadian Borrower fails to notify the Canadian Administrative Agent in writing not
later than 1:00 p.m., Toronto time, on the Business Day prior to any BA Maturity Date that the
Canadian Borrower intends to pay with the Canadian Borrower’s own funds the Bankers’ Acceptance
Liabilities due on such BA Maturity Date, or fails to make such payment, the Canadian Borrower
shall be deemed, for all purposes to have given the Canadian Administrative Agent notice of a
borrowing of a Canadian Prime Rate Loan pursuant to Section 2.03 for an amount equal to the
Principal Amount of such Bankers’ Acceptance; provided that:

               (i) the BA Maturity Date for such Bankers’ Acceptances shall be considered to be the date of
such borrowing;

44

 

               (ii) the proceeds of such Canadian Prime Rate Loan shall be used to pay the amount of the
Bankers’ Acceptance Liability due on such BA Maturity Date;

               (iii) each Canadian Tranche Lender which has made a maturing BA Loan (in accordance with
Section 2.24(g) hereof) shall continue to extend credit to the Canadian Borrower (without further
advance of funds to the Canadian Borrower) by way of a Canadian Base Rate Loan (if in US Dollars)
or a Canadian Prime Rate Loan (if in Canadian Dollars) in the Principal Amount equal to its
Applicable Percentage of the total amount of credit requested to be extended by Bankers’
Acceptances when the BA Loan was made; and

               (iv) the Canadian Administrative Agent shall promptly and in any event within three (3)
Business Days following the BA Maturity Date of such Bankers’
Acceptances, notify the Canadian Borrower in writing of the making of such Canadian Base Rate
Loan pursuant to this Section 2.24(f).

          (g) If, in the sole judgment of a Canadian Tranche Lender, such Lender is unable, as a result
of applicable law, customary market practice, or otherwise, to extend credit by way of Bankers’
Acceptance in accordance with this Agreement, such Lender shall give notice to such effect to the
Canadian Administrative Agent and the Canadian Borrower prior to 11:00 a.m., Toronto time, on the
date of the requested credit extension (which notice may, if so stated therein, remain in effect
with respect to subsequent requests for extension of credit by way of Bankers’ Acceptance until
revoked by notice to the Canadian Administrative Agent, the US Administrative Agent, and the
Canadian Borrower) and shall make available to the Canadian Administrative Agent, in accordance
with Section 2.01 hereof prior to 2:00 p.m., Toronto time, on the date of such requested credit
extension, a Canadian Dollar Eurodollar Loan or, if such Lender is unable to make a Canadian Dollar
Eurodollar Loan, a US Dollar Eurodollar Loan (each such Loan, a “BA Loan”) in the Principal Amount
equal to such Lender’s Applicable Percentage of the total amount of credit requested to be extended
by way of Bankers’ Acceptances. Such BA Loan shall have an Interest Period equal to the term of
the Bankers’ Acceptances for which it is a substitute and shall bear interest throughout such
Interest Period applicable to that BA Loan at a rate per annum equal to the Canadian Dollar LIBO
Rate or the US Dollar LIBO Rate, as the case may be, plus the Eurodollar Margin. On the maturity
date of the Bankers’ Acceptances issued concurrently with the advance of the BA Loan, the Canadian
Borrower issuing such Bankers’ Acceptances shall, at its option, pay to each Canadian Tranche
Lender which made a BA Loan, in satisfaction of the BA Loan, an amount equal to the Principal
Amount of such BA Loan, together with accrued interest thereon, failing which such Principal Amount
shall be continued as a Canadian Base Rate Loan (if in US Dollars) or a Canadian Prime Rate Loan
(if in Canadian Dollars); provided, however, all accrued interest on such BA Loan shall be paid in
full on such maturity.

          (h) If a Canadian Tranche Lender determines in good faith, which determination shall be final,
conclusive and binding upon the Canadian Borrower, and notifies the Canadian Borrower that, by
reason of circumstances affecting the money market, (i) there is no market for Bankers’ Acceptances
generally or of a requested duration, or (ii) the demand for Bankers’ Acceptances is insufficient
to allow the sale or trading of the Bankers’ Acceptances created and purchased hereunder generally
or in connection with a requested duration, then the right of the Canadian Borrower to request
Bankers’ Acceptances of the affected duration from

45

 

that Canadian Tranche Lender shall be suspended
until such Lender determines that the circumstances causing such suspension no longer exist and
such Lender so notifies the Canadian Borrower, and any Bankers’ Acceptance Request for an affected
duration which is outstanding shall be canceled and the Bankers’ Acceptances requested therein
shall not be made and a Bankers’ Acceptance having the shortest duration available (or if none) a
Canadian Base Rate Loan (if in US Dollars) or a Canadian Prime Rate Loan (if in Canadian Dollars)
shall be made in its place.

          (i) It is the intention of the Canadian Administrative Agent, the Canadian Tranche Lenders,
and the Canadian Borrower that, except to the extent a Canadian Tranche Lender advises otherwise,
pursuant to the Depository Bills and Notes Act (“DBNA”), all Bankers’ Acceptances accepted by the
Canadian Tranche Lenders under this Agreement shall be
issued in the form of a “depository bill” (as defined in the DBNA), deposited with the
Canadian Depository for Securities Ltd. and made payable to CDS & Co. In order to give effect to
the foregoing, the Canadian Administrative Agent shall, subject to the approval of the Canadian
Borrower and the Canadian Tranche Lenders, establish and notify the Canadian Borrower and the
Canadian Tranche Lenders of any procedure, consistent with the terms of this Agreement and the
requirements of the DBNA, as is reasonably necessary to accomplish such intention, including: (i)
any instrument held by the Canadian Administrative Agent or a Canadian Tranche Lender for the
purposes of Bankers’ Acceptances shall have marked prominently and legibly on its face and within
its text, at or before the time of issue, the words “This is a depository bill subject to the
Depository Bills and Notes Act (Canada)”; (ii) any reference to the authentication of the Bankers’
Acceptances will be removed; and (iii) any reference to “bearer” will be removed and no Bankers’
Acceptance shall be marked with any words prohibiting negotiation, transfer or assignment of it or
of an interest in it.

          (j) (i) If any Event of Default shall have occurred and be continuing, on the Business Day
that the Canadian Borrower receives notice from Canadian Tranche Lenders with BA Exposure
representing greater than 662/3% of the total BA Exposure or, if the maturity of the Loans has been
accelerated, from the Canadian Administrative Agent, the US Administrative Agent, or the Majority
Lenders, demanding the deposit of cash collateral pursuant to this paragraph, and (ii) on the
Business Day that the Canadian Borrower receives notice from either the Canadian Administrative
Agent acting alone, the US Administrative Agent acting alone, or the Majority Lenders demanding
deposit of cash collateral pursuant to Section 2.08(b), the Canadian Borrower shall deposit in an
account with the Canadian Administrative Agent, in the name of the Canadian Administrative Agent
and for the benefit of the Canadian Tranche Lenders, an amount in cash equal to the BA Exposure of
the Canadian Borrower as of such date plus any accrued and unpaid interest thereon; provided that
the obligation to deposit such cash collateral shall become effective immediately, and such deposit
shall become immediately due and payable, without demand or other notice of any kind, upon the
occurrence of any Event of Default described in Section 7.01(g) or Section 7.01(h). Any such
deposit shall be held by the Canadian Administrative Agent as collateral for the payment and
performance of the obligations of the Canadian Borrower under this Agreement. The Canadian
Administrative Agent shall have exclusive dominion and control, including the exclusive right of
withdrawal, over such account. Other than any interest earned on the investment of such deposits,
which investments shall be made at the option and sole discretion of the Canadian Administrative
Agent and at the Canadian Borrower’s risk and expense, such deposits shall not bear interest.
Interest or profits, if any, on

46

 

such investments shall accumulate in such account. Moneys in such
account shall be applied by the Canadian Administrative Agent for the satisfaction of the
obligations of the Canadian Borrower with respect to the BA Exposure at such time or, if the
maturity of the Loans has been accelerated (but subject to the consent of Canadian Tranche Lenders
with BA Exposure representing greater than 50% of the total BA Exposure), be applied to satisfy
other obligations of the Canadian Borrower under this Agreement. If the Canadian Borrower is
required to provide an amount of cash collateral hereunder as a result of the occurrence of an
Event of Default, such amount (to the extent not applied as aforesaid) shall be returned to the
Canadian Borrower within two (2) Business Days after all Events of Default have been cured or
waived.

ARTICLE III

REPRESENTATIONS AND WARRANTIES

     Section 3.01 Representations of the US Borrower. The US Borrower represents and warrants to each of the Administrative Agents, the Lenders and
each Issuing Bank that:

          (a) The US Borrower (i) has been duly incorporated and is validly existing and in good
standing under the laws of the State of Delaware, and (ii) is qualified to do business as a foreign
corporation and is in good standing in each jurisdiction of the United States in which the
ownership of its properties or the conduct of its business requires such qualification and where
the failure to so qualify would constitute a Material Adverse Change.

          (b) This Agreement, the Transactions and all other Loan Documents to which the US Borrower is
a party have been duly authorized, executed and delivered by the US Borrower, and each of this
Agreement, its Notes and the other Loan Documents to which it is a party constitutes a valid and
binding agreement of the US Borrower, enforceable in accordance with its respective terms, subject
to the effect of applicable bankruptcy, insolvency or similar laws affecting creditors’ rights
generally and equitable principals of general applicability. The US Borrower’s Notes have been duly
authorized by the US Borrower and, when executed, issued and delivered pursuant hereto for value
received, will constitute valid and binding obligations of the US Borrower, enforceable in
accordance with their terms, except as (i) may be limited by bankruptcy, insolvency or similar laws
affecting creditors’ rights generally, and (ii) rights of acceleration and the availability of
equitable remedies may be limited by equitable principles of general applicability. There are no
actions, suits or proceedings pending or, to the knowledge of the US Borrower, threatened against
the US Borrower or the Canadian Borrower which purports to affect the legality, validity or
enforceability of this Agreement, any other Loan Document or any of their respective Notes.

          (c) The execution, delivery and performance of this Agreement by the US Borrower and the
execution, issuance, delivery and performance by the US Borrower of its Notes will not violate or
conflict with (i) the restated certificate of incorporation or bylaws of the US Borrower, or (ii)
any indenture (including the Public Indenture), loan agreement or other similar agreement or
instrument binding on the US Borrower.

          (d) To the knowledge of the US Borrower, on the Effective Date there are no actions, suits, or
proceedings pending or, to the knowledge of the US Borrower, threatened against the US Borrower
before any Governmental Authority as to which, in the opinion of the

47

 

US Borrower, there is a
reasonable possibility of an adverse determination and that, if adversely determined, could
reasonably be expected, individually or in the aggregate, to constitute a Material Adverse Change.

          (e) The consolidated balance sheets of the US Borrower and its consolidated Subsidiaries as of
December 31, 2002 and 2003, and the related consolidated statements of income, stockholders’ equity
and cash flows for each of the years in the three-year period ended December 31, 2003, audited by
KPMG LLP, present fairly, in all material respects, the
consolidated financial position of the US Borrower and its consolidated Subsidiaries as of
December 31, 2002 and 2003, and the results of their operations and their cash flows for each of
the years in the three-year period ended December 31, 2003, in conformity with GAAP applied on a
consistent basis.

          (f) From June 30, 2004 through the Effective Date, there has been no Material Adverse Change.

          (g) Neither the US Borrower nor any Subsidiary is (i) an “investment company” as defined in,
or subject to regulation under, the Investment Company Act of 1940, or (ii)”holding company” as
defined in, or subject to regulation under, the Public Utility Holding Company Act of 1935.

          (h) No ERISA Event has occurred or is reasonably expected to occur that, when taken together
with all other such ERISA Events for which liability is reasonably expected to occur, could
reasonably be expected to result in a Material Adverse Change. The present value of all
accumulated benefit obligations of all underfunded Plans (based on the assumptions used for
purposes of Statement of Financial Accounting Standards No. 87) did not, as of the date of the most
recent financial statements reflecting such amounts, exceed the fair market value of the assets of
all such underfunded Plans by an amount that could reasonably be expected to be a Material Adverse
Change.

          (i) Neither the Information Memorandum nor any of the other reports, financial statements,
certificates or other information furnished by or on behalf of the US Borrower to the Agents or any
Lender in connection with the negotiation of this Agreement or delivered hereunder (as modified or
supplemented by other information so furnished), taken as a whole, contains any material
misstatement of fact or omits to state any material fact necessary to make the statements therein,
in the light of the circumstances under which they were made, not misleading; provided that, with
respect to projected financial information, the US Borrower represents only that such information
was prepared in good faith based upon assumptions believed to be reasonable at the time.

          (j) On the date hereof, the US Borrower’s “significant subsidiaries” (as defined in Regulation
S-X of the Commission under the Securities and Exchange Act of 1934) are listed on Schedule
II hereto.

          (k) The US Borrower has filed all United States Federal income tax returns and all other
material tax returns and reports required to be filed (or obtained extensions with respect thereto)
and has paid all taxes required to have been paid by it, except (i) taxes the

48

 

validity of which is
being contested in good faith by appropriate proceedings, and with respect to which the US
Borrower, to the extent required by GAAP, has set aside on its books adequate reserves or (ii) to
the extent the failure to do so (individually or collectively) would not reasonably be expected to
result in a Material Adverse Change.

          (l) No Event of Default has occurred and is continuing.

     Section 3.02 Representations of the Canadian Borrower. The Canadian Borrower represents and warrants, as to itself, to the Administrative Agents, the
Canadian Tranche Lenders, and each Issuing Bank with respect to the Canadian Tranche that:

          (a) The Canadian Borrower has been duly incorporated and is validly existing and in good
standing under the laws of the Province of Alberta.

          (b) This Agreement, the Transactions and all other Loan Documents to which the Canadian
Borrower is a party have been duly authorized, executed and delivered by the Canadian Borrower and
each of this Agreement and each of its Notes constitutes a valid and binding agreement of the
Canadian Borrower, enforceable in accordance with their respective terms, subject to the effect of
applicable bankruptcy, insolvency or similar laws affecting creditors’ rights generally and
equitable principles of general applicability. The Canadian Borrower’s Notes have been duly
authorized by the Canadian Borrower and, when executed, issued and delivered pursuant hereto for
value received, will constitute valid and binding obligations of the Canadian Borrower, enforceable
in accordance with their terms, except as (i) may be limited by bankruptcy, insolvency or similar
laws affecting creditors’ rights generally, and (ii) rights of acceleration and the availability of
equitable remedies may be limited by equitable principles of general applicability. There is no
action, suit or proceeding pending or, to the knowledge of the Canadian Borrower, threatened
against the Canadian Borrower which purports to affect the legality, validity or enforceability of
this Agreement, any other Loan Document to which it is a party, or any of its Notes.

          (c) The execution, delivery and performance of this Agreement by the Canadian Borrower, and
the execution, issuance, delivery and performance by the Canadian Borrower of its Notes will not
violate or conflict with (i) the charter or bylaws or partnership agreement, as the case may be, of
the Canadian Borrower or, (ii) any indenture, loan agreement or other similar agreement or
instrument binding on the Canadian Borrower.

proceeding in equity or at law), including, (1) the possible unavailability of specific
performance, injunctive relief or any other equitable remedy, and (2) concepts of materiality,
reasonableness, good faith and fair dealing; (ii) no authorization, consent or approval of any
governmental body or agency of the Province of Alberta which has not been obtained is required in
connection with the execution, delivery and performance by the Guarantor and by the Canadian
Borrower of this Agreement and the Canadian Borrower of its Notes, (iii) the choice of New York law
is valid choice of law, (iv) the submission by the Canadian Borrower to the jurisdiction of the New
York Courts is valid, and (v) an Alberta Court would enforce a judgment of a New York Court
rendered with respect to the Credit Agreement and the Notes, without a review of the merits. Such
opinion shall also address such other matters as the Administrative Agents shall reasonably
request.

In rendering such opinion, Macleod Dixon LLP may assume matters covered by other opinions delivered
hereunder and may state that they have relied as to certain matters on information obtained from
public officials, officers of the Canadian Borrower and the Guarantor and other sources believed by
them to be responsible.

          (k) The US Administrative Agent (or its counsel) shall have received a favorable opinion of an
associate general counsel or the general counsel of the Canadian Borrower, to the effect that:

               (i) the Canadian Borrower is validly existing and, in the case of ACC, in good standing under
the laws of the Province of Alberta;

               (ii) this Agreement and the Notes of the Canadian Borrower have been duly authorized, executed
and delivered by the Canadian Borrower;

               (iii) the execution, delivery and performance by the Canadian Borrower of this Agreement and
its Notes will not violate the charter or bylaws or partnership agreement, as the case may be, of
the Canadian Borrower, each as in effect on the date of such opinion;

               (iv) the execution, delivery and performance of this Agreement and the execution, issuance,
delivery and performance by the Canadian Borrower of its Notes will not (A) violate any applicable
provision of any applicable law or applicable order or (B) violate any provision of any indenture,
loan agreement or other similar agreement or instrument known to such counsel (having made due
inquiry with respect thereto) binding on the Canadian Borrower or affecting its property; and

               (v) to the knowledge of such counsel (having made due inquiry with respect thereto), there is
no proceeding pending or threatened before any court or administrative agency which, in the opinion
of such counsel, will result in a final determination which would result in a Material Adverse
Change.

In rendering such opinion, the associate general counsel or the general counsel of the Canadian
Borrower, as the case may be, shall opine only as to matters governed by the federal laws of Canada
and the laws of the Province of Alberta. Such counsel may also state that he/she has relied on
certificates of public officials, certificates of officers of the Canadian Borrower and other
sources believed by him/her to be responsible.

          (l) There shall not have occurred a Material Adverse Change.

full any loans and other amounts then outstanding thereunder, together with accrued interest
thereon and any unpaid fees then accrued.

responsible officer of the US Borrower relating to the USA Patriot Act.

extend any Letter of Credit, is subject to the further conditions precedent that, on the relevant
Borrowing Date, Section 6.01(g)(i) and Section 6.01(g)(ii) shall be true with respect to such Loan,
issuance, amendment, renewal or extension and such Borrowing, issuance, amendment, renewal or
extension, as applicable, shall be deemed to constitute a certification by the US Borrower on
behalf of each Borrower that such statements are true.

herein or the transactions contemplated hereby (including the costs and expenses which any Borrower

the Canadian Borrower, as the case may be, such remittance to be in accordance with the
proportionate amount of the indemnification made by each respective Lender.

     Section 8.05 Action on Instructions of Lenders. The Administrative Agents shall in all cases be fully protected in acting or refraining from

all of the Lenders.

     Section 8.06 Employment of Agents. The Administrative Agents may employ agents and attorneys-in-fact and shall not be answerable,

60

assignment or transfer thereof satisfactory to the Administrative Agents signed by such payee shall
have been filed with the US Administrative Agent or the Canadian Administrative Agent, as
applicable.

     Section 8.08 Rights as a Lender. With respect to its Commitment and the Loans made by it, the Administrative Agents shall have
the same rights and powers hereunder and under any agreement executed and delivered pursuant to the
terms hereof as any US Tranche Lender or Canadian Tranche Lender, respectively, and may exercise
the same as though it were not the US Administrative Agent or the Canadian Administrative Agent, as
the case may be, and the term “US Tranche Lender” or “US Tranche Lenders” shall, unless the context
otherwise indicates, include the US Administrative Agent in its capacity as a US Tranche Lender
hereunder and thereunder; and the terms “Canadian Tranche Lender” and “Canadian Tranche Lenders”
shall, unless the context otherwise indicates, include the Canadian Administrative Agent in its
capacity as a
Lender hereunder and thereunder. The US Administrative Agent and its respective Affiliates may

Administrative Agent shall be required to keep itself informed as to the performance or observance
by any Borrower of this Agreement or any other document referred to or provided for herein or
therein or to inspect the properties or books of any Borrower. Except for notices, reports and
other documents expressly required to be furnished to the Lenders by the Administrative Agents
hereunder, the Administrative Agents shall have no duty or responsibility to provide any Lender

Borrower or which may at any time come into possession of Agent or any of their respective
Affiliates.

     Section 8.10 Events of Default. If either of the Administrative Agents receives actual knowledge of an Event of Default
hereunder, such Agent shall promptly inform the Lenders thereof. Neither Administrative Agent

such Event of Default and stating that such notice is a “Notice of Default.”

61

 

     Section 8.11 Successor Agent. Subject to the appointment and acceptance of a successor Administrative Agent as provided in
this paragraph, either Administrative Agent may resign at any time by notifying the Lenders and the
Borrowers. Upon any such resignation, the Majority Lenders shall have the right, in consultation
with the Borrowers, to appoint a successor. If no successor shall have been so appointed by the
Majority Lenders and shall have accepted such appointment within 30 days after such retiring
Administrative Agent gives notice of its resignation, then such retiring Administrative Agent may,
on behalf of the Lenders, appoint a successor Administrative Agent which shall be a bank with an
office in New York, New York, or an Affiliate of any such bank, in the case of the US
Administrative Agent, or be a bank with an office in Toronto, Canada, or an Affiliate of such bank,
in the case of the Canadian Administrative Agent. Upon the acceptance of its appointment as US
Administrative Agent or Canadian Administrative Agent, as the case may be, hereunder by a
successor, such successor shall succeed to and become vested with all
the rights, powers, privileges and duties of such retiring Administrative Agent, and the retiring
Administrative Agent shall be discharged from its duties and obligations hereunder. The fees
payable by the Borrowers to a successor Administrative Agent shall be the same as those payable to
its predecessor unless otherwise agreed between the Borrowers and such successor. After an
Administrative Agent’s resignation hereunder, the provisions of this ARTICLE VIII and Section 9.03
shall continue in effect for the benefit of such retiring Administrative Agent, its sub-agents and
their respective Related Parties in respect of any actions taken or omitted to be taken by any of
them while it was acting as an Administrative Agent hereunder.

     Section 8.12 Other Agents. Nothing contained in this Agreement shall be construed to impose any obligation or duty
whatsoever on any Persons named on the cover of this Agreement or elsewhere in this Agreement as
Syndication Agents, or Document Agents, other than those applicable to all Lenders as such.

     Section 9.02 Waivers; Amendments.

          (a) No failure or delay by the US Administrative Agent, the Canadian Administrative Agent, any
Issuing Bank or any Lender in exercising any right or power hereunder shall operate as a waiver
thereof, nor shall any single or partial exercise of any such right or power, or any abandonment or
discontinuance of steps to enforce such a right or power, preclude any other or further exercise
thereof or the exercise of any other right or power. The rights and remedies of the US
Administrative Agent, the Canadian Administrative Agent, any Issuing Bank, and the Lenders
hereunder are cumulative and are not exclusive of any rights or remedies that they would otherwise
have. No waiver of any provision of this Agreement or consent to any departure by the US Borrower
or the Canadian Borrower therefrom shall in any event be effective unless the same shall be
permitted by paragraph (b) of this Section, and then such waiver or consent shall be effective only
in the specific instance and for the purpose for which given. Without limiting the generality of
the foregoing, to the fullest extent permitted by applicable law, the making of a Loan or issuance
of a Letter of Credit shall not be construed as a waiver of any Event of Default, regardless of
whether the US Administrative Agent, the Canadian Administrative Agent, any Lender or any Issuing
Bank may have had notice or knowledge of such Event of Default at the time.

          (b) Neither this Agreement nor any provision hereof may be waived, amended or modified except
pursuant to an agreement or agreements in writing entered into by the Borrowers and the Majority
Lenders or by the Borrowers and the Administrative Agents with the consent of the Majority
Lenders; provided that no such agreement shall (i) increase the Commitment of any Lender without
the written consent of such Lender, (ii) reduce any Principal Amount or LC Disbursement or reduce
the rate of interest thereon, or reduce any fees payable hereunder, without the written consent of
each Lender affected thereby, (iii) postpone the scheduled date of payment of any Principal Amount
or LC Disbursement, or any interest thereon, or any fees payable hereunder, or reduce the amount
of, waive or excuse any such payment, or postpone the scheduled date of expiration of any
Commitment, without the written consent of each Lender affected thereby, (iv) extend the expiry
date of any Letter of Credit beyond the then scheduled Revolving Commitment Termination Date
without the written consent of each Lender,

63

 

(v) change Section 2.13(a) or Section 2.13(c) in a
manner that would alter the pro rata sharing of payments required thereby, without the written
consent of each Lender, (vi) change Section 6.01, without the consent of each Lender, (vii) release
the US Borrower, in its capacity as Guarantor, from the Guaranty or limit its liability in respect
of the Guaranty without the written consent of each Canadian Tranche Lender, or (viii) change any
of the provisions of this Section or the definition of “Majority Lenders” or any other provision
hereof specifying the number or percentage of Lenders required to waive, amend or modify any rights
hereunder or make any determination or grant any consent hereunder, without the written consent of
each Lender; provided further that no such agreement shall amend, modify or otherwise affect the
rights or duties of the US Administrative Agent, the Canadian Administrative Agent or any Issuing Bank
hereunder without the prior written consent of the US Administrative Agent, the Canadian
Administrative Agent, or such Issuing Bank.

     Section 9.03 Expenses; Indemnity; Damage Waiver.

          (a) The Borrowers shall pay (i) all reasonable out-of-pocket expenses incurred by the
Administrative Agents and their Affiliates, including the reasonable fees, charges and
disbursements of counsel for the US Administrative Agent and the Canadian Administrative Agent (on
a solicitor and his own client basis), in connection with the syndication (prior to the date
hereof) of the credit facilities provided for herein, the preparation, execution, delivery and
administration of this Agreement or any amendments, modifications or waivers of the provisions
hereof (whether or not the transactions contemplated hereby or thereby shall be consummated), (ii)
all reasonable out-of-pocket expenses incurred by any Issuing Bank in connection with the issuance,
amendment, renewal or extension of any Letter of Credit or any demand for payment thereunder and
(iii) all reasonable out-of-pocket expenses incurred by the US Administrative Agent, the Canadian
Administrative Agent, any Issuing Bank or any Lender, including the fees, charges and disbursements
of any counsel for the US Administrative Agent, the Canadian Administrative Agent (on a solicitor
and his own client basis), any Issuing Bank any US Tranche Lender or any Canadian Tranche Lender
(on a solicitor and his own client basis), in connection with the enforcement or protection of its
rights in connection with this Agreement, including its rights under this Section, or in connection
with the Loans made or Letters of Credit issued hereunder, including all such reasonable
out-of-pocket expenses incurred during any workout, restructuring or negotiations in respect of
such Loans or Letters of Credit. Notwithstanding anything to the contrary, the Borrowers shall not
have any obligation to pay the fees or expenses of any Lender or any Administrative Agent in
connection with any assignment of, or the grant of any participation in, any rights of a Lender
under or in connection with this Agreement; provided that the provisions of this sentence shall not
apply to any Lender substituted for a Defaulting Lender pursuant to Section 9.13 (b) and (c).

          (b) The Borrowers shall indemnify each Administrative Agent, each Issuing Bank and each
Lender, and each Related Party of any of the foregoing Persons (each such Person being called an

liabilities and related expenses, including the fees, charges and disbursements of any counsel for
any Indemnitee (on a solicitor and his own client basis), incurred by or asserted against any

this Agreement or any agreement or instrument contemplated hereby, the performance by the parties
hereto of their respective obligations hereunder or the

64

other transactions contemplated hereby, (ii) any Loan or Letter of Credit or the use of the
proceeds therefrom (including any refusal by any Issuing Bank to honor a demand for payment under a

with the terms of such Letter of Credit), (iii) any actual or alleged presence or release of
hazardous materials on or from any property owned or operated by any Borrower or any Subsidiary, or
any environmental liability related in any way to any Borrower or any Subsidiary, or (iv) any
actual or prospective claim, litigation,
investigation or proceeding relating to any of the foregoing, whether based on contract, tort
or any other theory and regardless of whether any Indemnitee is a party thereto; provided that such
indemnity shall not, as to any Indemnitee, be available to the extent that such losses, claims,
damages, liabilities or related expenses either (i) did not result directly or indirectly from the
action or inaction of any Borrower or any Subsidiary, or (ii) resulted from the gross negligence,
unlawful conduct or willful misconduct of such Indemnitee.

          (c) To the extent that the Borrowers fail to pay any amount required to be paid by them to any
Administrative Agent, or any Issuing Bank under paragraph (a) or (b) of this Section, each Lender
severally agrees to pay to such Administrative Agent or such Issuing Bank, as the case may be, such
Lender’s Applicable Percentage (determined as of the time that the applicable unreimbursed expense
or indemnity payment is sought) of such unpaid amount; provided that the unreimbursed expense or
indemnified loss, claim, damage, liability or related expense, as the case may be, was incurred by
or asserted against such Administrative Agent, or such Issuing Bank in its capacity as such.

          (d) All amounts due under this Section shall be payable promptly after written demand therefor
together with a copy of the invoice(s) or other documentation setting forth in reasonable detail
the amount demanded and the matter(s) to which it relates.

Section 5.05 or with the prior written consent of each Lender (and any attempted assignment or
transfer by any Borrower without such consent shall be null and void) and (ii) no Lender may assign
or otherwise transfer its rights or obligations hereunder except in accordance with this Section.
Nothing in this Agreement, expressed or implied, shall be construed to confer upon any Person
(other than the parties hereto, their respective successors and assigns permitted hereby (including
any Affiliate of an Issuing Bank that issues any Letter of Credit), Participants (to the extent
provided in paragraph (c) of this Section) and, to the extent expressly contemplated hereby, the

          (b) (i) Subject to the conditions set forth in paragraph (b)(ii) below, any Lender may assign
to one or more assignees all or a portion of its rights and obligations under this Agreement
(including all or a portion of its US Tranche Commitment or Canadian Tranche Commitment, as the
case may be, or, in the case of a Dual Lender, both and the Loans at the time

65

 

owing to it) with the
prior written consent (such consent not to be unreasonably withheld or delayed) of:

                    (A) the US Borrower, provided that no consent of the US Borrower shall be required for an
assignment to a Lender, an Affiliate of a Lender or, if an Event
of Default under Section 7.01(a), (b), (g), (h) or (i) has occurred and is continuing, any
other assignee; and

                    (B) the US Administrative Agent, provided that no consent of the US Administrative Agent
shall be required for an assignment of any Revolving Commitment to an assignee that is a Lender
with a Commitment immediately prior to giving effect to such assignment or an Affiliate of a
Lender.

               (ii) Assignments shall be subject to the following additional conditions:

                    (A) except in the case of an assignment to a Lender or an Affiliate of a Lender or an
assignment of the entire remaining amount of the assigning Lender’s Commitment or Loans of any
Class, the amount of the Commitment or Loans of the assigning Lender subject to each such
assignment (determined as of the date the Assignment and Assumption with respect to such assignment
is delivered to the Administrative Agents) shall not be less than $10,000,000 unless each of the
US Borrower and the US Administrative Agent otherwise consent, provided that no such consent of the
US Borrower shall be required if an Event of Default under Section 7.01(a), (b), (g), (h) or (i)
has occurred and is continuing;

                    (B) each partial assignment shall be made as an assignment of a proportionate part of all the
assigning Lender’s rights and obligations under this Agreement and, unless each of the US Borrower
and the US Administrative Agent otherwise consent, shall result in the assigning Lender having no
less than $10,000,000 in Commitments and Loans after giving effect to such assignment;

                    (C) the parties to each assignment shall execute and deliver to the US Administrative Agent an
Assignment and Assumption, together with a processing and recordation fee of $3,500;

                    (D) each assigning Lender that is a Dual Lender shall assign its Commitment in whole or in
part only to an assignee that, after giving effect to such assignment will be a Dual Lender;

                    (E) the assignee of a Dual Lender shall purchase pro rata percentages of such Dual Lender’s US
Tranche Commitment and Canadian Tranche Commitment;

                    (F) the assignee, if it shall not be a Lender, shall deliver to the Administrative Agents an
Administrative Questionnaire; and

                    (G) after giving effect to the assignment to it, each assignee of an assigning Canadian
Tranche Lender shall be a Canadian Tranche Lender.

66

 

               (iii) Subject to acceptance and recording thereof pursuant to paragraph (b)(v) of this
Section, from and after the effective date specified in each Assignment and Assumption the assignee
thereunder shall be a party hereto and, to the extent of the interest assigned by such Assignment
and Assumption, have the rights and obligations of a Lender under
this Agreement, and the assigning Lender thereunder shall, to the extent of the interest
assigned by such Assignment and Assumption, be released from its obligations under this Agreement
(and, in the case of an Assignment and Assumption covering all of the assigning Lender’s rights and
obligations under this Agreement, such Lender shall cease to be a party hereto but shall continue
to be entitled to the benefits of Section 2.14, Section 2.16, Section 2.22 and Section 9.03). Any
assignment or transfer by a Lender of rights or obligations under this Agreement that does not
comply with this Section 9.04 shall be treated for purposes of this Agreement as a sale by such
Lender of a participation in such rights and obligations in accordance with paragraph (c) of this
Section.

               (iv) The US Administrative Agent and the Canadian Administrative Agent, acting for this
purpose as an agent of the Applicable Borrowers, shall maintain at one of its offices in New York
City and Toronto, Canada, respectively, a copy of each Assignment and Assumption delivered to it
and a register for the recordation of the names and addresses of the Lenders, and the Commitment
of, and principal amount of the Loans and LC Disbursements owing to, each Lender pursuant to the
terms hereof from time to time (the “Register”). The entries in the Register shall be prima facie
evidence of the existence and amounts of the obligations recorded therein, and the Borrowers, the
Administrative Agents, each Issuing Bank and the Lenders may treat each Person whose name is
recorded in the Register pursuant to the terms hereof as a Lender hereunder for all purposes of
this Agreement, notwithstanding notice to the contrary. The Register shall be available for
inspection by any Borrower, any Issuing Bank and any Lender, at any reasonable time and from time
to time upon reasonable prior notice.

               (v) Upon its receipt of a duly completed Assignment and Assumption executed by an assigning
Lender and an assignee, the assignee’s completed Administrative Questionnaire (unless the assignee
shall already be a Lender hereunder), the processing and recordation fee referred to in paragraph
(b)(ii)(C) of this Section and any written consent to such assignment required by paragraph (b)(i)
of this Section and upon satisfaction of the additional conditions set forth in paragraph (b)(ii)
of this Section, the US Administrative Agent shall accept such Assignment and Assumption and (A) in
the case of the US Tranche Commitment, record the information contained therein in the Register
maintained at the New York office of the US Administrative Agent and (B) in the case of the
Canadian Tranche Commitment, instruct the Canadian Administrative Agent to record the information
contained therein in the Register maintained at the Toronto, Canada office of the Canadian
Administrative Agent. No assignment shall be effective for purposes of this Agreement unless it
has been recorded in the applicable Register as provided in this paragraph.

          (c) (i) Any Lender may, without the consent of any Borrower, either Administrative Agent or
any Issuing Bank, sell participations to one or more banks or other entities (a “Participant”) in
all or a portion of such Lender’s rights and obligations under this Agreement (including all or a
portion of its Commitment and the Loans owing to it); provided that (A) such Lender’s obligations
under this Agreement shall remain unchanged, (B) such Lender shall remain solely responsible to the
other parties hereto for the performance of such

67

 

obligations and (C) the Borrowers, the
Administrative Agents, each Issuing Bank and the other Lenders shall continue to deal solely and
directly with such Lender in connection with such Lender’s rights and obligations under this
Agreement. Any agreement or instrument pursuant to which a Lender sells such a participation shall
provide that such Lender shall retain the sole right
to enforce this Agreement and to approve any amendment, modification or waiver of any
provision of this Agreement; provided that such agreement or instrument may provide that such
Lender will not, without the consent of the Participant, agree to any amendment, modification or
waiver described in the first proviso to Section 9.02(b) that affects such Participant. Subject to
paragraph (c)(ii) of this Section, the Borrowers agree that each Participant shall be entitled to
the benefits of Section 2.14, Section 2.16 and Section 2.22 to the same extent as if it were a
Lender and had acquired its interest by assignment pursuant to paragraph (b) of this Section.
Notwithstanding anything to the contrary, unless otherwise contractually agreed, no Participant
shall be entitled to the benefits of Section 9.08 as though it were a Lender,.

               (ii) A Participant shall not be entitled to receive any greater payment under Section 2.14 or
Section 2.16 than the applicable Lender would have been entitled to receive with respect to the
participation sold to such Participant, unless the sale of the participation to such Participant is
made with the Borrowers’ prior written consent. A Participant that would be a Foreign Lender if it
were a Lender shall not be entitled to the benefits of Section 2.16 unless the Borrowers are
notified of the participation sold to such Participant and such Participant agrees, for the benefit
of the Borrowers, to comply with Section 2.16(e) and Section 2.16(g) as though it were a Lender.

          (d) Any Lender may at any time pledge or assign a security interest in all or any portion of
its rights under this Agreement to secure obligations of such Lender, including any pledge or
assignment to secure obligations to a Federal Reserve Bank in accordance with Regulation A of the
Board of Governors of the Federal Reserve System, and to a trustee for the benefit of holders of
debt securities issued by such Lender, and this Section shall not apply to any such pledge or
assignment of a security interest; provided that no such pledge or assignment of a security
interest shall release a Lender from any of its obligations hereunder or substitute any such
pledgee or assignee for such Lender as a party hereto.

     Section 9.05 Survival. All covenants, agreements, representations and warranties made by the Borrowers herein and in
the certificates or other instruments delivered in connection with or pursuant to this Agreement
shall be considered to have been relied upon by the other parties hereto and shall survive the
execution and delivery of this Agreement and the making of any Loans and issuance of any Letters of
Credit, regardless of any investigation made by any such other party or on its behalf and
notwithstanding that either Administrative Agent, any Issuing Bank or any Lender may have had
notice or knowledge of any Event of Default or incorrect representation or warranty at the time any
credit is extended hereunder, and shall continue in full force and effect as long as the principal
of or any accrued interest on any Loan or any fee or any other amount payable under this Agreement
is outstanding and unpaid or any Letter of Credit is outstanding and so long as the Commitments
have not expired or terminated. The provisions of Section 2.14, Section 2.16, Section 2.22,
Section 2.23, Section 9.03, this Section 9.05, and ARTICLE VIII shall survive and remain in full
force and effect regardless of the consummation of the transactions contemplated hereby, the
repayment of the Loans, the expiration or

68

 

termination of the Letters of Credit and the Commitments
or the termination of this Agreement or any other provision hereof.

     Section 9.06 Counterparts; Integration; Effectiveness. This Agreement may be executed in counterparts (and by different parties hereto on different
counterparts), each of which shall constitute an original, but all of which when taken together
shall constitute a single contract. This Agreement, the other Loan Documents and any separate
letter agreements with respect to fees payable to the US Administrative Agent constitute the entire
contract among the parties relating to the subject matter hereof and supersede any and all previous
agreements and understandings, oral or written, relating to the subject matter hereof. Except as
provided in Section 6.01, this Agreement shall become effective when it shall have been executed by
the Administrative Agents and when the US Administrative Agent shall have received counterparts
hereof which, when taken together, bear the signatures of each of the other parties hereto, and
thereafter shall be binding upon and inure to the benefit of the parties hereto and their
respective successors and assigns. Delivery of an executed counterpart of a signature page of this
Agreement by telecopy shall be effective as delivery of a manually executed counterpart of this
Agreement.

     Section 9.07 Severability. Any provision of this Agreement held to be invalid, illegal or unenforceable in any jurisdiction
shall, as to such jurisdiction, be ineffective to the extent of such invalidity, illegality or
unenforceability without affecting the validity, legality and enforceability of the remaining
provisions hereof; and the invalidity of a particular provision in a particular jurisdiction shall
not invalidate such provision in any other jurisdiction.

     Section 9.08 Right of Setoff. If (a) an Event of Default shall have occurred and be continuing, and (b) the principal of the
Loans has been accelerated each Lender is hereby authorized at any time and from time to time, to
the fullest extent permitted by law, to set off and apply any and all deposits (general or special,
time or demand, provisional or final) at any time held and other obligations at any time owing by
such Lender to or for the credit or the account of any Borrower against any of and all the
obligations of the Borrowers now or hereafter existing under this Agreement held by such Lender,
irrespective of whether or not such Lender shall have made any demand under this Agreement and
although such obligations may be unmatured. The rights of each Lender under this Section are in
addition to other rights and remedies (including other rights of setoff) which such Lender may
have.

     Section 9.09 Governing Law; Jurisdiction; Consent to Service of Process.

          (a) This Agreement and the Notes shall be construed in accordance with and
governed by the law of the State of New York.

          (b) Each party hereto hereby irrevocably and unconditionally submits, for itself and its
property, to the nonexclusive jurisdiction of the courts of the Supreme Court of the State of New
York, sitting in New York County and of the United States District Court of the Southern District
of New York, and any appellate court from either thereof, in any action or
proceeding arising out of or relating to this Agreement, the Notes, or the other Loan
Documents, or for recognition or enforcement of any judgment, and each of the parties hereto hereby
irrevocably and unconditionally agrees that all claims in respect of any such action or proceeding

69

 

may be heard and determined in such New York State court or, to the extent permitted by law, in
such Federal court. Each of the parties hereto agrees that a final judgment in any such action or
proceeding shall be conclusive and may be enforced in other jurisdictions by suit on the judgment
or in any other manner provided by law. Nothing in this Agreement or any other Loan Document shall
affect any right that either Administrative Agent, any of the other agents, any Issuing Bank or any
Lender may otherwise have to bring any action or proceeding relating to this Agreement against any
Borrower or its properties in the courts of any jurisdiction.

          (c) Each party to this Agreement irrevocably consents to service of process in the manner
provided for notices in Section 9.01. Nothing in this Agreement will affect the right of any party
to this Agreement to serve process in any other manner permitted by law.

     Section 9.10 WAIVER OF JURY TRIAL. EACH PARTY HERETO HEREBY WAIVES, TO THE FULLEST EXTENT PERMITTED BY APPLICABLE LAW, ANY RIGHT IT
MAY HAVE TO A TRIAL BY JURY IN ANY LEGAL PROCEEDING DIRECTLY OR INDIRECTLY ARISING OUT OF OR
RELATING TO THE LOAN DOCUMENTS OR THE TRANSACTIONS CONTEMPLATED HEREBY (WHETHER BASED ON CONTRACT,
TORT OR ANY OTHER THEORY). EACH PARTY HERETO (a) CERTIFIES THAT NO REPRESENTATIVE, AGENT OR
ATTORNEY OF ANY OTHER PARTY HAS REPRESENTED, EXPRESSLY OR OTHERWISE, THAT SUCH OTHER PARTY WOULD
NOT, IN THE EVENT OF LITIGATION, SEEK TO ENFORCE THE FOREGOING WAIVER AND (b) ACKNOWLEDGES THAT IT
AND THE OTHER PARTIES HERETO HAVE BEEN INDUCED TO ENTER INTO THIS AGREEMENT BY, AMONG OTHER THINGS,
THE MUTUAL WAIVERS AND CERTIFICATIONS IN THIS SECTION.

     Section 9.11 Headings. Article and Section headings and the Table of Contents used herein are for convenience of
reference only, are not part of this Agreement and shall not affect the construction of, or be
taken into consideration in interpreting, this Agreement.

     Section 9.12 Confidentiality. Each of the Administrative Agents, each Issuing Bank and the Lenders agrees to maintain the
confidentiality of the Information (as defined below), except that Information may be disclosed (a)
to its and its Affiliates’ directors, officers, employees and agents, including accountants, legal
counsel and other advisors who have a reason to use such Information in connection with the
administration of this Agreement (it being understood that the Persons to whom such disclosure is
made will be informed of the confidential nature of such Information and instructed to keep such
Information confidential and will agree to use the Information solely for the purpose of such
administration), (b) to the extent requested by any regulatory authority or any self-
regulatory body having authority to regulate or oversee any aspect of any Lender’s (or any
Affiliate of such Lender) business or property, (c) to the extent required by applicable laws or
regulations or by any subpoena or similar legal process, (d) to any other party to this Agreement,
(e) in connection with the exercise of any remedies hereunder or any suit, action or proceeding
relating to this Agreement or the enforcement of rights hereunder, (f) subject to an agreement
containing provisions substantially the same as those of this Section, to any assignee of or
Participant in, or any prospective assignee of or Participant in, any of its rights or obligations
under this Agreement, or to any counterparty (or its advisor) to any swap, securitization, or
derivative transaction referencing or involving any

70

 

of its rights or obligations under this
Agreement, (g) with the consent of the Borrowers, or (h) to the extent such Information (i) becomes
publicly available other than as a result of a breach of this Section or (ii) becomes available to
the US Administrative Agent, the Canadian Administrative Agent, any Issuing Bank, or any Lender on
a non-confidential basis from a source other than a Borrower or any of its Affiliates. For the
purposes of this Section, “Information” means all information received from the Borrowers relating
to the Borrowers or their respective business, other than any such information that is available to
either Administrative Agent, any Issuing Bank, or any Lender on a non-confidential basis prior to
disclosure by a Borrower; provided that, in the case of information received from a Borrower after
the date hereof, such information is clearly identified at the time of delivery as confidential.
Any Person required to maintain the confidentiality of Information as provided in this Section
shall be considered to have complied with its obligation to do so if such Person has exercised the
same degree of care to maintain the confidentiality of such Information as such Person would accord
to its own confidential information.

     Section 9.13 Termination and Substitution of Lender.

          (a) If (i) the obligation of any Lender to make Eurodollar Loans or continue Loans as
Eurodollar Loans has been suspended pursuant to Section 2.15, or (ii) any Lender has demanded
compensation under Section 2.14 or Section 2.16, the Borrowers may, upon three Business Days’
notice to such Lender through the Administrative Agents, prepay in full all of the outstanding
Loans of such Lender, or its assignee, together with accrued interest thereon to the date of
prepayment and all other amounts payable hereunder to such Lender accrued to the date of
prepayment, and concurrently therewith terminate this Agreement with respect to such Lender by
giving notice of such termination to the Administrative Agents and such Lender.

          (b) If any Lender shall become a Defaulting Lender, the Borrowers may, in their sole
discretion and without prejudice to any right or remedy that the Borrowers may have against such
Defaulting Lender with respect to, on account of, arising from or relating to any event pursuant to
which such Lender shall be a Defaulting Lender, upon notice to such Defaulting Lender, the US
Administrative Agent and the Canadian Administrative Agent, (i) if at such time there are no Loans
or LC Exposure of such Defaulting Lender outstanding, terminate this Agreement with respect to such
Defaulting Lender, or (ii) if at such time such Defaulting Lender shall have Credit Exposure
outstanding, either (A) terminate any Commitment of such Lender in excess (any such excess being
the “Excess Commitment”) of such Credit Exposure and leave any Loans or LC Exposure of such
Defaulting Lender in place for payment or satisfaction in the ordinary course in accordance with
the other provisions of this Agreement (in
which case the total Commitments hereunder shall be immediately reduced by the amount of such
Defaulting Lender’s Excess Commitment and thereafter reduced as such Credit Exposure is paid or
satisfied) or (B) subject to obtaining a substitute lender or lenders to assume the Commitment of
such Defaulting Lender pursuant to subsection (c) below, terminate this Agreement with respect to
such Defaulting Lender and prepay in full the outstanding Loans of such Defaulting Lender together
with accrued interest to the date of prepayment, provided that the provisions of Section 2.19 shall
not apply to any such prepayment.

          (c) If the Borrowers elect to terminate this Agreement with respect to any Lender under
Section 9.13(b)(ii)(B), the Borrowers shall cooperate in good faith with the US

71

 

Administrative
Agent and the Canadian Administrative Agent, to seek a mutually satisfactory substitute lender or
lenders (which may be one or more of the Lenders) to assume the Commitment of such relevant Lender
and until a substitute lender (or lenders) has been found and documents reasonably acceptable to
each of the substitute lender or lenders, the Administrative Agents and the Borrowers have been
executed to provide for the assignment of the rights and obligations of the Defaulting Lender to
the substitute lender or lenders in accordance with Section 9.04, the total Commitments hereunder
shall be reduced by an amount equal to such terminated Lender’s Commitment.

     Section 9.14 USA Patriot Act Notice. Each US 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 Lender to identify the US Borrower and
such Subsidiaries in accordance with the USA Patriot Act.

ARTICLE X

GUARANTY

     Section 10.01 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 of and interest on each Canadian Tranche Revolving Loan and all
Bankers’ Acceptances when due, whether at maturity, by acceleration, by redemption or otherwise,
and all other monetary obligations of the Canadian Borrower under this Agreement 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 Agent or any
Canadian Tranche Lender against the Canadian Borrower or any other Person or against such 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

72

 

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, Letter of Credit, 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 10.02 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 or against any Canadian Tranche Lender 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 Canadian Tranche Commitments
terminated.

     Applicable Margin for Alternate Base Rate Loans, Canadian Base Rate Loans and Canadian Prime
Rate Loans is zero percent (0%). At all times while the Combined Credit Exposure equals or exceeds
50% of the availability under this Agreement, a Utilization Fee shall be applicable as more
specifically set forth in Section 2.04(b).

     Ratings in the above pricing grid relate to US Borrower’s senior unsecured non-credit enhanced
publicly held indebtedness (the “Index Debt”). For purposes of the foregoing, (i) if
either Moody’s or S&P shall not have in effect a rating for the Index Debt (other than by reason of
the circumstances referred to in the last sentence of this definition), then such rating agency
shall be deemed to have established a rating in Category 6; (ii) if the ratings established or

Agreement, the Syndication Agents and the Document Agents named therein, the Canadian Borrower,
defined below, hereby appoints each Canadian Tranche Lender (as defined in the Credit Agreement)
(individually, the “Lender”), acting by its duly authorized signatories (the “Attorney”) for the
time being at the Lender’s main branch in Toronto, Ontario (the “Branch of Account”), the attorney
of the Canadian Borrower:

	 	1.	 	to sign for and on behalf and in the name of the Canadian Borrower as drawer,

information as set out above and the request of the Canadian Borrower to the Lender to accept such
Drafts and deliver the same, or deposit the same with a “clearing house” under the DBNA, against

endorsed, discounted and/or delivered in accordance herewith prior to the time at which such
revocation becomes effective. This power of attorney may be terminated by the Lender at any time
upon not less than five (5) Business Days’ written notice to the Canadian Borrower in accordance
with Section 2.24 of the Credit Agreement.

Lender and the obligations of the Canadian Borrower with respect to the indemnities of the Canadian
Borrower above stated with respect to all matters arising prior in time to any such revocation or
termination.

     This power of attorney is in addition to and not in substitution for any agreement to which
the Lender and the Canadian Borrower are parties.

     This power of attorney shall be governed in all respects by the laws of the Province of
Ontario and the laws of Canada applicable therein and each of the Canadian Borrower and the Lender

is being concurrently consummated and (b) attached thereto is a true and duly completed and
executed copy of the certificate of merger to be filed with the Secretary of State of the
State of Delaware in connection with the Kerr-McGee Merger.

          “KMG Letters of Credit” — the letters of credit listed on Schedule IV attached to the

     2. Amendment to Section 2.05(c). Effective at the KMG Effective Time, Section 2.05(c)
of the Credit Agreement is hereby amended in its entirety to read as follows:

     (c) Each Letter of Credit shall expire at or prior to the close of business on the
date selected by the Requesting Borrower, which shall not be later than the earlier of (i)
the date one year after the date of the issuance of such Letter of Credit, other than in the
case of a KMG Letter of Credit, which may expire on a date more than one year after the date
of its issuance (or, in the case of any renewal or extension of such Letter of Credit,
including a KMG Letter of Credit, one year after such renewal or extension), and (ii) the
date that is five (5) Business Days prior to the Maturity Date.

     3. Amendment to Section 5.02. Effective at the KMG Effective Time, Section 5.02 of the
Credit Agreement is hereby amended in its entirety to read as follows:

     Section 5.02 Indebtedness to Capitalization Ratio. At the end of each calendar
quarter through and including the calendar quarter ending September 30, 2007, Consolidated
Indebtedness divided by Total Capital shall not exceed 75%. At the end of each calendar
quarter thereafter, Consolidated Indebtedness divided by Total Capital shall not exceed 60%.
For purposes of this provision “Total Capital” is equal to the sum of Consolidated
Stockholders’ Equity, exclusive of the effect of any noncash writedowns made subsequent to
the date hereof, plus Consolidated Indebtedness, each at such time.

     4. Addition to ARTICLE IX Miscellaneous. ARTICLE IX of the Credit Agreement is hereby
amended and supplemented by adding thereto a new section, to be Section 9.14, to read in its
entirety as follows:

     Section 9.14. Partial Releases. Upon (a) the completion of and not prior to the sale
of all of the ownership interests in the Canadian Borrower, (b) the payment in full of all
Canadian Tranche Revolving Credit Exposure outstanding on the date such sale is completed
(or, with respect to any Canadian LC Exposure or BA Exposure outstanding on such date, the
deposit of cash collateral pursuant to Sections 2.05(j) and 2.24(j), respectively), together
with accrued and unpaid interest thereon and all other amounts payable to the Canadian
Tranche Lenders and the Canadian Administrative Agent hereunder accrued to such date (if
any), and (c) the prior written request of the US Borrower, and at the US Borrower’s sole
expense, the Canadian Borrower shall cease to be a Borrower under this Agreement and the
Canadian Tranche Commitments shall be terminated, at which point the Canadian Borrower and
the Canadian Administrative Agent shall be released from their obligations hereunder, no
event or circumstance with respect to the Canadian Borrower shall constitute a Default or
Event of Default, and the US Borrower shall no longer serve as Guarantor.

     5. Amendment to “Change of Control” Definition. Upon the release of the Canadian
Borrower pursuant to Section 9.14 of the Credit Agreement, as amended hereby, the definition of
“Change of Control” shall be amended to delete subclause (c) of that definition such that the sale
of the Canadian Borrower shall not constitute a Change of Control. For the sake of clarity, the
sale by the US Borrower of all of the ownership interests in the Canadian Borrower shall not
constitute a Default or Event of Default.

3

 

     6. KMG Letters of Credit. The parties hereto hereby acknowledge and agree that each
of the KMG Letters of Credit shall, from and after the KMG Effective Time, constitute Letters of
Credit issued under the Credit Agreement, as amended hereby. Furthermore, the parties hereto
hereby acknowledge and agree that each of the issuers of the KMG Letters of Credit shall, from and
after the KMG Effective Time, be an Issuing Bank under the Credit Agreement, as amended hereby, for
purposes of the KMG Letters of Credit, and as such, shall have all of the rights, benefits and
obligations of an Issuing Bank under the Credit Agreement, as amended hereby, with respect to the
KMG Letters of Credit.

     7. Conditions Precedent. This First Amendment shall become effective as of the date
first set forth above when each of the following conditions is satisfied (or waived in accordance
with Section 9.02 of the Credit Agreement):

          (a) The US Administrative Agent shall have received from the Majority Lenders, the
Administrative Agents, each Issuing Bank and the Borrowers, counterparts (in such number as may be
requested by the US Administrative Agent) of this First Amendment executed on behalf of such
Persons (or, in the case of any such Person as to which an executed counterpart shall not have been
received, telegraphic, telex, or other written confirmation from such Person of the execution of a
counterpart hereof by such Person).

          (b) Both before and after giving effect to the terms of this First Amendment (i) the
representations and warranties contained in ARTICLE III of the Credit Agreement are true and
accurate on and as of the date hereof as though made on and as of such date (except to the extent
such representations and warranties relate solely to an earlier date), and (ii) no Default has
occurred which is continuing. By executing and delivering this First Amendment, the Borrowers
hereby represent and warrant to the Administrative Agents, the Lenders and each Issuing Bank that
the conditions precedent set forth in the clauses (i) and (ii) of this paragraph (b) have been
satisfied.

          (c) The US Administrative Agent shall have received such other documents as the US
Administrative Agent or special counsel to the US Administrative Agent may reasonably request.

     8. Miscellaneous.

          (a) The provisions of the Credit Agreement, as amended by this First Amendment, shall remain
in full force and effect following the effectiveness of this First Amendment.

          (b) This First Amendment may be executed by one or more of the parties hereto in any number of
separate counterparts, and all of such counterparts taken together shall be deemed to constitute
one and the same instrument. Delivery of this First Amendment by facsimile transmission shall be
effective as delivery of a manually executed counterpart hereof.

          (c) This First Amendment, the Credit Agreement, as amended hereby, and the other Loan
Documents represent the final agreement between the parties and may not be contradicted by evidence
of prior, contemporaneous, or unwritten oral agreements of the parties. There are no subsequent
oral agreements between the parties.

4

 

          (d) THIS FIRST AMENDMENT (INCLUDING, BUT NOT LIMITED TO, THE VALIDITY AND ENFORCEABILITY
HEREOF) SHALL BE GOVERNED BY, AND CONSTRUED IN ACCORDANCE WITH, THE LAWS OF THE STATE OF NEW YORK.

          (e) This First Amendment shall be binding upon and inure to the benefit of the parties hereto
and their respective successors and assigns.
