Loan (to the extent that such Advance would not, when added to the
outstanding Swing Line Loans, exceed the Swing Line Loan Subcommitment), in
an amount rounded up to the nearest Cdn. $50,000, as the case may be, to
place Company in a minimum net credit position of zero.

     (c) Swing Line Loans by Request. In addition to the automatic advance

Pro Rata Share of the Refunded Swing Line Loans shall be deemed to be paid with the
proceeds of a Revolving Loan made by Swing Line Lender, and such portion of the

Loans of Swing Line Lender but shall instead constitute part of Swing Line Lender’s
outstanding Revolving Loans. If any portion of any such amount paid (or deemed to
be paid) to Swing Line Lender should be recovered by or on behalf of Company from
Swing Line Lender in any bankruptcy proceeding, in any assignment for the benefit of
creditors or otherwise, the loss of the amount so recovered shall be ratably shared

Commitments are terminated at a time when any Swing Line Loans are outstanding, each
Revolving Lender shall be deemed to, and hereby agrees to, have purchased an
assignment of such outstanding Swing Line Loans in an amount equal to its Pro Rata
Share (calculated, in the case of the foregoing clause (2), immediately prior to
such termination of the Revolving Loan Commitments) of the unpaid amount of such
Swing Line Loans together with accrued interest thereon. Upon one Business Day’s
notice from Swing Line Lender, each Revolving Lender shall deliver to Swing Line
Lender an amount equal to its respective assignment in same day funds at the Funding
and Payment Office. In order to further evidence such assignment (and without
prejudice to the effectiveness of the assignment provisions set forth above), each
Revolving Lender agrees to enter into an Assignment Agreement at the request of
Swing Line Lender in form and substance reasonably satisfactory to Swing Line
Lender. In the event any Revolving Lender fails to make available to Swing Line
Lender the amount of such Revolving Lender’s assignment as provided in this
paragraph, Swing Line Lender shall be entitled to recover such amount on demand from
such Revolving Lender together with interest thereon at the rate customarily used by

(First Amended and Restated Credit Agreement)

provided in this paragraph, Swing Line Lender shall promptly distribute to each such
other Revolving Lender its Pro Rata Share of such payment.

     (f) Revolving Lenders’ Obligations. Anything contained herein to the
contrary notwithstanding, each Revolving Lender’s obligation to make Revolving Loans
for the purpose of repaying any Refunded Swing Line Loans pursuant to subsection
2.1A(ii)(d) and each Revolving Lender’s obligation to purchase an assignment of any
unpaid Swing Line Loans pursuant to the immediately preceding paragraph shall be
absolute and unconditional and shall not be affected by any circumstance, including
(1) any set-off, counterclaim, recoupment, defense or other right which such
Revolving Lender may have against Swing Line Lender, Company or any other Person for
any reason whatsoever; (2) the occurrence or continuance of an Event of Default or a
Potential Event of Default; (3) any adverse change in the business, operations,
properties, assets, condition (financial or otherwise) or prospects of Company or
any of its Subsidiaries; (4) any breach of this Agreement or any other Loan Document
by any party thereto; or (5) any other circumstance, happening or event whatsoever,
whether or not similar to any of the foregoing; provided that, unless Requisite
Lenders agree otherwise, Swing Line Lender shall not make a Swing Line Loan if at
the time of the request for a Swing Line Loan the Swing Line Lender has received
written notice from Company or a Lender that a Potential Event of Default or an
Event of Default has occurred and is continuing (unless and until it has been
confirmed that no Potential Event of Default or Event of Default has occurred and is
continuing).

     (g) Indemnification. Each Revolving Lender agrees to indemnify Swing
Line Lender (to the extent not reimbursed by Company), rateably according to its Pro
Rata Share from and against any and all losses and claims of any kind or nature
whatsoever which may be imposed on, incurred by, or asserted against the Swing Line
Lender in any way relating to or arising out of any Swing Line Loans,
provided that no Lender shall be liable for any portion of such losses or
claims resulting from the Swing Line Lender’s gross negligence or willful
misconduct.

to subsection 4.3C) shall be in an aggregate minimum amount of Cdn.$1,000,000 and multiples of

Borrowing no later than 11:00 a.m. (Toronto time) at least one Business Day in advance of the
proposed Funding Date.

          Whenever Company desires that Lenders make Revolving Loans by way of Bankers’ Acceptances, it

(Toronto time) at least three Business Days in advance of the proposed Funding Date.

          Whenever Company desires that Swing Line Lender make a Swing Line Loan pursuant to clause
2.1A(ii)(c), it shall deliver to Swing Line Lender, with a copy to Administrative Agent, a duly
executed Notice of Borrowing no later than 11:00 a.m. (Toronto time) on the proposed Funding Date
(which for greater certainty may be delivered by facsimile transmission).

          Company shall notify Administrative Agent prior to the funding of any Loans requested by
Company in the event that any of the matters to which Company is required to certify in the
applicable Notice of Borrowing is no longer true and correct as of the applicable Funding Date. The
acceptance by Company of the proceeds of any Loans (including Swing Line Loans) shall constitute a
re-certification by Company, as of the applicable Funding Date, as to the matters to which Company
is required to certify in any Notice of Borrowing.

          Except as set out in subsection 2.6C, a Notice of Borrowing for, or a Notice of
Conversion/Rollover for Conversion to, or Rollover of, Bankers’ Acceptances shall be irrevocable,
and Company shall be bound to make a borrowing or to effect a Conversion or Rollover in accordance
therewith.

     C. Disbursement of Funds. All Revolving Loans (other than Swing Line Loans made by Swing Line
Lender) shall be made by Lenders simultaneously and proportionately to their respective Pro Rata
Shares, it being understood that neither Administrative Agent nor any Lender shall be responsible
for any default by any other Lender in that other Lender’s obligation to make a Loan requested
hereunder nor shall the Revolving Loan Commitment of any Lender to make the particular type of Loan
requested be increased or decreased as a result of a default by any other Lender in that other
Lender’s obligation to make a Loan requested hereunder.

          Promptly after receipt by Administrative Agent of a Notice of Borrowing by way of Prime Rate
Loans (other than Swing Line Loans) pursuant to subsection 2.1B, Administrative Agent shall notify
each Lender for the type of Loan of the proposed borrowing. Each such

(First Amended and Restated Credit Agreement)

Lender shall make the amount of its Loan available to Administrative Agent not later than
12:00 noon (Toronto time) on the applicable Funding Date in same day funds at the Funding and
Payment Office. Except as provided in subsection 2.1A(ii) with respect
to Revolving Loans used to repay Refunded Swing Line Loans, or subsection 4.3B
with respect to Revolving Loans used to reimburse any Issuing Lender for the amount of a
drawing under a Letter of Credit issued by it, upon satisfaction or waiver of the conditions
precedent specified in subsections 6.1 (in the case of Loans made on
the Restatement Date) and 6.2 (in the case of all Loans),
Administrative Agent shall make the proceeds of such Loans available to Company on the applicable
Funding Date by causing an amount of same day funds equal to the proceeds of all such Loans
received by Administrative Agent from Lenders to be credited to an account of Company maintained by
Company with Administrative Agent at the Funding and Payment Office by 12:00 noon on the Funding
Date, or as otherwise instructed by Company in writing and acceptable to Administrative Agent.

          After receipt by Swing Line Lender of a Notice of Borrowing by way of Swing Line Loans
pursuant to subsection 2.1A(ii)(c), Swing Line Lender shall make the amount
of its Swing Line Loan available to Company not later than 12:00 noon (Toronto time) on the
applicable Funding Date, in each case in same day funds to be credited to an account of Company

Lender.

          Unless Administrative Agent shall have been notified by any Lender prior to a Funding Date for
any Loans that such Lender does not intend to make available to Administrative Agent the amount of
such Lender’s Prime Rate Loan requested on such Funding Date, Administrative Agent may assume that
such Lender has made such amount available to Administrative Agent on such Funding Date and
Administrative Agent may, in its sole discretion, but shall not be obligated to, make available to
Company a corresponding amount on such Funding Date. If such corresponding amount is not in fact
made available to Administrative Agent by such Lender, Administrative Agent shall be entitled to
recover such corresponding amount on demand from such Lender together with interest thereon, for
each day from such Funding Date until the date such amount is paid to Administrative Agent, at the
customary rate set by Administrative Agent for the correction of errors among banks for three
Business Days and thereafter at the Prime Rate. If such Lender does not pay such corresponding
amount forthwith upon Administrative Agent’s demand therefor, Administrative Agent shall promptly
notify Company and Company shall immediately pay such corresponding amount to Administrative Agent
together with interest thereon, for each day from such Funding Date until the date such amount is
paid to Administrative Agent, at the rate payable under this Agreement for Prime Rate Loans.
Nothing in this subsection 2.1C shall be deemed to relieve any Lender from its obligation to fulfill
its Revolving Loan Commitments hereunder or to prejudice any rights that Company may have against
any Lender as a result of any default by such Lender hereunder.

     D. The Register. Administrative Agent shall maintain at its address referred to in subsection
12.8 a register for the recordation of, and shall record, the names
and addresses of Lenders and the Revolving Loan Commitment, Swing Line Loan Subcommitment,
Revolving Loans and Swing Line Loans of each Lender from time to time (the “Register”). Company,

(First Amended and Restated Credit Agreement)

- 41 -

 

Administrative Agent and Lenders shall deem and treat the
Persons listed as Lenders in the Register as the holders and owners of the corresponding Revolving
Loan Commitments and Loans listed therein for all purposes hereof; all amounts owed with respect to
any Revolving Loan Commitment or Loan shall be owed to the Lender listed in the Register as the
owner thereof; and any request, authority or consent of any Person who, at the time of making such
request or giving such authority or consent is listed in the Register as a Lender, shall be
conclusive and binding on any subsequent holder, assignee or transferee of the corresponding
Revolving Loan Commitments or Loans. Each Lender shall record on its internal records the amount
of its Loans and Revolving Loan Commitments and each payment in respect hereof, and any such
recordation shall be prima facie evidence of the contents thereof, absent manifest error, subject
to the entries in the Register, which shall, absent manifest error, govern in the event of any
inconsistency with any Lender’s records. Failure to make any recordation in the Register or in any
Lender’s records, or any error in such recordation, shall not affect any Loans or Revolving Loan
Commitments or any Obligations in respect of any Loans.

     2.2 Interest on the Loans.

     A. Rate of Interest. Subject to the provisions of subsection 2.6, each Prime Rate Loan shall bear interest on the unpaid principal amount thereof from the
date made through maturity (whether by acceleration or otherwise) at a rate determined by reference
to the Prime Rate.

          Subject to the provisions of subsection 2.6, each Swing Line
Loan shall bear interest on the unpaid principal amount thereof from the date made through maturity
(whether by acceleration or otherwise) at a rate determined by reference to the Prime Rate.

          The applicable basis for determining the rate of interest with respect to any Revolving Loan
shall be selected by Company initially at the time a Notice of Borrowing is given with respect to
such Loan pursuant to subsection 2.1B, and the basis for determining
the interest rate with respect to any Revolving Loan may be changed from time to time pursuant to
subsection 2.2C. If on any day a Revolving Loan is outstanding with respect to which notice has not
been delivered to Administrative Agent in accordance with the terms of this Agreement specifying
the applicable basis for determining the rate of interest, then for that day that Loan shall bear
interest determined by reference to the Prime Rate.

     (i) Subject to the provisions of subsections 2.2D, 2.2I and 2.6, the Revolving Loans shall bear interest or accrue fees through maturity as follows:

     (a) if a Prime Rate Loan (other than a Swing Line Loan), then interest at the
sum of the Prime Rate plus 2.0% per annum;

     (b) if a Swing Line Loan, then interest at the sum of the Prime Rate
plus 1.5% per annum, for the sole account of Swing Line Lender; and

     (c) if a Bankers’ Acceptance, then interest and fees as provided in Section 3.

(First Amended and Restated Credit Agreement)

- 42 -

 

     (d) if a Letter of Credit, then fees and interest as provided in Section 4.

     B. Interest Payments. Subject to the provisions of subsection 2.2D, interest on each Prime Rate
Loan (including Swing Line Loans) shall be payable monthly in arrears on each Interest Payment Date
in respect of the immediately preceding calendar month based on the actual number of days in such
month, upon any prepayment of that Loan (to the extent accrued on the amount being prepaid), and at
maturity (including final maturity), provided that in the event any Revolving Loans that
are Prime Rate Loans are prepaid pursuant to subsection 2.4A(i), interest accrued on such Loans through
the date of such prepayment shall be payable on the next succeeding Interest Payment Date
applicable to Prime Rate Loans (or, if earlier, at final maturity).

     C. Conversion or Rollover. Subject to the provisions of Section 3,
Company shall have the option:

     (i) to convert at any time all or any part of its outstanding Revolving Loans (other
than Swing Line Loans) equal to Cdn.$1,000,000 and multiples of Cdn.$100,000 in excess of
that amount from Prime Rate Loans to an issue of Bankers’ Acceptances, or from Bankers’
Acceptances to Prime Rate Loans;

     (ii) upon the expiration of a BA Interest Period applicable to Bankers’ Acceptances, to
rollover all or any portion of such Loan equal to Cdn.$1,000,000 and multiples of
Cdn.$100,000 in excess of that amount as a new issue of Bankers’ Acceptances;

provided that an issue of Bankers’ Acceptances may only be converted into a Prime Rate Loan
on the expiration date of the BA Interest Period applicable thereto.

          Company shall deliver a duly executed Notice of Conversion/Rollover to Administrative Agent no
later than 11:00 a.m. (Toronto time) at least one Business Day in advance of the proposed
Conversion date (in the case of a Conversion to a Prime Rate Loan) and at least three Business Days
in advance of the proposed Conversion/Rollover date (in the case of a Conversion to, or a Rollover
of, Bankers’ Acceptances). Administrative Agent shall notify each Lender of any Loan subject to a
Notice of Conversion/Rollover. A Conversion or Rollover shall not be subject to the conditions to
making a Loan set out in subsection 6.2.

     D. Default Rate. Upon the occurrence and during the continuance of any Event of Default, the
outstanding principal amount of all Loans and, to the extent permitted by Applicable
Law, any interest payments thereon not paid when due and any fees and other amounts then due
and payable hereunder, shall thereafter bear interest (including post-petition interest in any
proceeding under any Bankruptcy Laws) payable upon demand at a rate that is 2% per annum in excess
of the interest rate otherwise payable under this Agreement with respect to the applicable Loans
(or, in the case of any such fees and other amounts, at a rate which is 2% per annum in excess of
the interest rate otherwise payable under this Agreement for Prime Rate Loans), provided
that (i) in the case of Bankers’ Acceptances, upon the expiration of the BA Interest Period in
effect at the time any such increase in interest rate is effective such Bankers’

(First Amended and Restated Credit Agreement)

- 43 -

 

Acceptances shall
thereupon become Prime Rate Loans and shall thereafter bear interest payable upon demand at a rate
which is 2% per annum in excess of the interest rate otherwise payable under this Agreement for
Prime Rate Loans, and (ii) subclause 4.3D(i) shall apply in respect of
fees payable in respect of Letters of Credit, and not this subclause 2.2D. Payment or acceptance of
the increased rates of interest provided for in this subsection 2.2D is not a permitted alternative to
timely payment and shall not constitute a waiver of any Event of Default or otherwise prejudice or
limit any rights or remedies of Administrative Agent or any Lender.

     E. Computation of Interest. Interest on the Loans shall be computed on the basis of a 365-day
year, in each case for the actual number of days elapsed in the period during which it accrues. In
computing interest on any Loan, the date of the making of such Loan or, with respect to a Prime
Rate Loan being converted from Bankers’ Acceptances, the date of Conversion to such Prime Rate
Loan, as the case may be, shall be included, and the date of payment of such Loan or, with respect
to a Prime Rate Loan being converted to Bankers’ Acceptances, the date of Conversion of such Prime
Rate Loan, as the case may be, shall be excluded, provided that if a Loan is repaid on the
same day on which it is made, one day’s interest shall be paid on that Loan.

     F. Prima Facie Evidence. Each determination by Administrative Agent (or by the Issuing Lender
as applicable) of the amount of interest, fees or other amounts due from Company hereunder shall be
prima facie evidence of the accuracy of such determination.

     G. Accrual. All interest, fees and other amounts payable by Company hereunder shall accrue
daily, be computed as described herein, and be payable both before and after demand, maturity,
default and judgment.

     H. No Merger. To the extent permitted by Applicable Law, the covenant of Company to pay
interest at the rates provided herein shall not merge in any judgment relating to any obligation of
Company to the Lenders or Administrative Agent and any provision of the Interest Act (Canada) or
Judgment Interest Act (Alberta) which restricts any rate of interest set forth herein shall be
inapplicable to this Agreement and to the extent permitted by Applicable Law is hereby waived by
Company.

     I. Maximum Rate. No interest or fee to be paid hereunder or under the other Loan Documents
shall be paid at a rate exceeding the maximum rate permitted by Applicable Law. In the event that
such interest or fee exceeds such maximum rate, such interest or fees shall be credited to Company
for application to any other Obligations then due and owing (or if no other
Obligations are then due and owing, refunded to Company), so as to be payable at the highest
rate recoverable under Applicable Law. For the purposes of the application of the Criminal Code
(Canada), the effective annual rate of interest shall be determined in accordance with generally
accepted actuarial practices and principles and in the event of any dispute, a certificate of a
Fellow of the Canadian Institute of Actuaries appointed by Administrative Agent shall be conclusive
for the purpose of such determination.

     J. Interest Act Rate Conversion. Whenever a rate of interest hereunder is calculated on the
basis of a year (the “deemed year”) which contains fewer days than the actual

(First Amended and Restated Credit Agreement)

- 44 -

 

number of days in the
calendar year of calculation, such rate of interest shall be expressed as a yearly rate for
purposes of the Interest Act (Canada) by multiplying such rate of interest by the actual number of
days in the calendar year of calculation and dividing it by the number of days in the deemed year.

     K. No Deemed Reinvestment. The principle of deemed reinvestment of interest shall not apply
to any interest calculation under this Agreement; all interest payments to be made hereunder shall
be paid without allowance or deduction for deemed reinvestment, before and after maturity, default
and judgment. The rates of interest specified in this Agreement are intended to be nominal rates
and not effective rates. Interest calculated hereunder shall be calculated using the nominal rate
method and not the effective rate method of calculation.

     2.3 Fees.

     A. Commitment Fees. Company agrees to pay to Administrative Agent, for distribution to each
Revolving Lender in proportion to that Lender’s Pro Rata Share, commitment fees for the period from
and including the Original Closing Date to and excluding the Revolving Loan Commitment Termination
Date equal to the average of the daily excess of the Revolving Loan Commitments over the sum of (i)
the aggregate principal amount of outstanding Revolving Loans including for certainty, the face
amount of all Bankers’ Acceptances and BA Discount Notes outstanding under the Revolving Loan
Commitment (but excluding any outstanding Swing Line Loans) plus (ii) the Letter of Credit
Usage, multiplied by .50% per annum, such commitment fees to be calculated on the basis of
a 365-day year and the actual number of days elapsed and to be calculated quarterly in arrears for
the three month periods ending on March 31, June 30, September 30 and December 31 of each year, and
payable on the first Business Day of the month immediately following each such quarter, commencing
on the first such Business Day to occur after the Restatement Date, and on the Revolving Loan
Commitment Termination Date.

     B. Other Fees. Company agrees to pay to Agents such fees in the amounts and at the times
separately agreed upon between Company and Agents.

such proposed termination or reduction, provided that any such partial reduction of
the Revolving Loan Commitments shall be in an aggregate minimum amount of Cdn.$1,000,000 and
multiples of Cdn.$100,000 in excess of that amount. Company’s notice to Administrative
Agent (who will promptly notify each Revolving Lender of such notice) shall designate the
date (which shall be a Business Day) of such termination or reduction and the amount of any
partial reduction, and such termination or reduction of the Revolving Loan Commitments shall
be effective on the date specified in Company’s notice and shall reduce the Revolving Loan
Commitment of each Revolving Lender proportionately to its Pro Rata Share.

     (iii) Mandatory Prepayments and Mandatory Reductions of Revolving Loan
Commitments. The Loans shall be prepaid and the Revolving Loan Commitments shall

proposed use of such portion of the Net Asset Sale Proceeds and such other
information with respect to such reinvestment as Administrative Agent may
reasonably request, and Company shall, or shall cause one or more of its

the Net Asset Sale Proceeds shall be applied to prepay outstanding Revolving
Loans (without a reduction in Revolving Loan Commitments) to the full extent
thereof. In addition, Company shall, no later than 170 days after receipt
of such Net Asset Sale Proceeds that have not theretofore been applied to

deliver to Administrative Agent an Officer’s Certificate demonstrating the
calculation of the amount of the applicable Net Asset Sale Proceeds, Net
Insurance/Condemnation Proceeds or Net Securities Proceeds, as the case may be, that
gave rise to such prepayment, collateralization and/or reduction. In the event that
Company shall subsequently determine that the actual amount was greater than the

additional prepayment of the Loans, or collateralization of Bankers’ Acceptances, in
an amount equal to the amount of such excess, and shall reduce the Revolving Loan
Commitments accordingly, all as provided in subsection 2.4A(iv) and subsection 2.4F,

Swing Line Loans, second the other Revolving Loans (including
collateralization of Bankers’ Acceptances), and third, collateralize Letters

     (1) first, to prepay the Swing Line Loans to the full extent
thereof and, to the extent required by the applicable provision of
subsection 2.4A(iii), to permanently reduce the Revolving Loan Commitments
by the amount of such prepayment,

     (2) second, to the extent of any remaining portion of such
amount, to prepay other Prime Rate Loans to the full extent thereof and, to
the extent required by the applicable provision of subsection 2.4A(iii), to
further permanently reduce the Revolving Loan Commitments by the amount of

Any mandatory reduction of Revolving Loan Commitments pursuant to this subsection
2.4 shall be in proportion to each Revolving Lender’s Pro Rata Share.

     (c) Application of Prepayments to Prime Rate Loans and Bankers’
Acceptances. Any prepayment of Revolving Loans shall be applied first to Prime
Rate Loans to the full extent thereof before application to collateralization of
Bankers’ Acceptances or Letters of Credit, provided that Company shall
first deposit the remainder of such prepayments not applied to prepay Prime Rate
Loans in the Collateral Account pursuant to subsection 2.4D to be applied thereafter
to prepay Bankers’ Acceptances having BA Interest Periods expiring on a date or
dates nearest the date of deposit in accordance with this subsection 2.4A(iv), upon

Account pursuant to subsection 2.4E to be applied thereafter to reimburse the
Issuing Lender for drawing on Letters of Credit expiring on a date

or dates nearest the date of deposit in accordance with this subsection
2.4A(iv), upon expiration of such Letters of Credit.

     B. General Provisions Regarding Payments.

     (i) Manner and Time of Payment. All payments by Company of principal,
interest, fees and other Obligations shall be made in Canadian Dollars in same day funds,
without defense, setoff or counterclaim, free of any restriction or condition, and delivered
to Administrative Agent not later than 12:00 noon (Toronto time) on the date due at the
Funding and Payment Office for the account of Lenders; funds received by Administrative
Agent after that time on such due date shall be deemed to have been paid by Company on the
next succeeding Business Day. Notwithstanding the foregoing, payments of amounts deposited
in the Collateral Account pursuant to the proviso to subsection 2.4A(iv)(c) shall be deemed
to have been paid by Company on the applicable date or dates such amounts are applied to
prepay Bankers’ Acceptances or to reimburse drawings under Letters of Credit. Company
hereby authorizes Administrative Agent to charge its accounts with Administrative Agent in
order to cause timely payment to be made to Administrative Agent of all principal, interest,
fees and expenses due hereunder (subject to sufficient funds being available in its accounts
for that purpose).

     (ii) Application of Payments to Principal and Interest. Except as provided in
subsection 2.2B, all payments in respect of the principal amount of any Prime Rate Loan
shall include payment of accrued interest on the principal amount being repaid or prepaid,
and all such payments shall be applied to the payment of interest before application to
principal.

     (iii) Apportionment of Payments. Aggregate payments of principal and interest
shall be apportioned among all outstanding Loans to which such payments relate, in each case
proportionately to Lenders’ respective Pro Rata Shares. Administrative Agent shall promptly
distribute to each Lender, at the account specified in the payment instructions set forth
below its name on the appropriate signature page hereof or at such other account as such
Lender may request in subsequent payment instructions delivered to Administrative Agent by
such Lender, its Pro Rata Share of all such payments received by Administrative Agent and
the commitment fees and letter of credit fees of such Lender, if any, when received by
Administrative Agent pursuant to subsection 2.3 and subsection 4.2.

     (iv) Payments on Business Days. Whenever any payment to be made hereunder
shall be stated to be due on a day that is not a Business Day, such payment shall be made on
the next succeeding Business Day and such extension of time shall be included in the
computation of the payment of interest hereunder or of the commitment fees hereunder, as the
case may be.

     C. Authorized Debit. Company authorizes and directs Administrative Agent to automatically
debit the Company’s bank accounts for all amounts payable by Company under this Agreement,
including the repayment of principal and the payment of interest and fees and all

 (First Amended and Restated Credit Agreement)

 - 50 -

 

charges agreed to by Company for the maintaining of the Company’s accounts. Administrative
Agent shall, as soon as is practical after making any such debit, inform Company of the amount
thereof and provide reasonable details of the calculation thereof.

     D. Collateralization of Bankers’ Acceptances. With respect to the prepayment or cash
collateralization of unmatured Bankers’ Acceptances to the extent required hereunder (it being
acknowledged that any requirement to pay or prepay Bankers’ Acceptances prior to their maturity
shall be construed as a requirement to provide cash collateral under this provision), Company shall
provide for the funding of such unmatured Bankers’ Acceptances by paying to and depositing with
Administrative Agent cash collateral for each such unmatured Bankers’ Acceptances; such cash
collateral deposited by Company shall be held by Administrative Agent in the Collateral Account
with interest to be credited to Company at rates prevailing at the time of deposit for similar
accounts with Administrative Agent. Such Collateral Account shall be held as security for the
obligations of Company in relation to such Bankers’ Acceptances and the security of Administrative
Agent thereby created shall rank in priority to all other Liens and adverse claims against such
cash collateral. Such cash collateral shall be applied to satisfy pro tanto the obligations of
Company for such Bankers’ Acceptances as they mature and Administrative Agent is hereby irrevocably
directed by Company to apply any such cash collateral to such maturing Bankers’ Acceptances.
Amounts held in such Collateral Account may not be withdrawn by Company; however, interest on such
deposited amounts shall be for the account of Company and may be withdrawn by Company so long as no
Potential Event of Default or Event of Default is then continuing. If after maturity of the
Bankers’ Acceptances for which such funds are held and application by Administrative Agent of the
amounts in such Collateral Accounts to satisfy the obligations of Company hereunder with respect to
the Bankers’ Acceptances being repaid, any excess remains, such excess shall be promptly paid by
Administrative Agent to Company so long as no Potential Event of Default or Event of Default is
then continuing.

     E. Collateralization of Letters of Credit. With respect to funding the cash collateralization
of unexpired Letters of Credit to the extent required hereunder (it being acknowledged that any
requirement to pay or prepay or collateralize Letters of Credit prior to their expiry date shall be
construed as a requirement to provide cash collateral under this provision), it is agreed that
Company shall provide for the funding of such unexpired Letters of Credit by paying to and
depositing with the Administrative Agent for the benefit of the Issuing Lender cash collateral for
each such unexpired Letter of Credit; such cash collateral deposited by Company shall be held by
the Administrative Agent for the benefit of the Issuing Lender in the Collateral Account with
interest to be credited to Company at rates prevailing at the time of deposit for similar accounts
with the Administrative Agent. Such Collateral Account shall be held as security for the
obligations of Company in relation to such Letters of Credit and the security of the Administrative
Agent and Issuing Lender thereby created in such cash collateral shall rank in priority to all
other Liens and adverse claims against such cash collateral. Such cash collateral shall be applied
to satisfy the obligations of Company for such Letters of Credit as payments are made thereunder
and the Issuing Lender is hereby irrevocably directed by Company to so apply any such cash
collateral. Amounts held in such Collateral Account may not be withdrawn by Company; however,
interest on such deposited amounts shall be for the

 (First Amended and Restated Credit Agreement)

 - 51 -

 

account of Company and may be withdrawn by Company so long as no Potential Event of Default or
Event of Default is then continuing. If after expiry of the Letters of Credit for which such funds
are held and application by the Administrative Agent and Issuing Lender of the amounts in such
Collateral Account to satisfy the obligations of Company hereunder with respect to the Letters of
Credit being repaid, any excess remains, such excess shall be promptly paid by Administrative Agent
to Company so long as no Potential Event of Default or Event of Default is then continuing.

     F. Application of Proceeds after Event of Default. Upon the occurrence and during the
continuance of an Event of Default, if requested by Requisite Lenders (a) all payments received on
account of the Obligations, whether from Company, from any Subsidiary Guarantor or otherwise, shall
be applied by Administrative Agent against the Obligations and (b) all proceeds received by
Collateral Agent in respect of any sale of, collection from, or other realization upon, all or any
part of the Collateral under any Collateral Document may, in the discretion of Administrative
Agent, be held by Collateral Agent as Collateral for, and/or (then or at any time thereafter)
applied in full or in part by Administrative Agent against, the applicable Obligations and Secured
Swap Obligations, in each case in the following order of priority:

     (i) to the payment of all costs and expenses of such sale, collection or other
realization, all other expenses, liabilities and advances made or incurred by Agents in
connection therewith, and all amounts for which Agents are entitled to compensation
(including the fees described in subsection 2.3), reimbursement and indemnification under
any Loan Document and all advances made by Administrative Agent thereunder for the account
of the applicable Loan Party, and to the payment of all costs and expenses paid or incurred
by Agents in connection with the Loan Documents, all in accordance with subsections 11.4,
12.2 and 12.3 and the other terms of this Agreement and the Loan Documents;

     (ii) thereafter, to the payment of all other Obligations (including the cash
collateralization of outstanding Letters of Credit) and the obligations under Secured Swap
Obligations for the ratable benefit of the holders thereof (subject, in the case of amounts
to be applied to the Obligations, to the provisions of subsection 2.4B(ii) hereof); and

     (iii) thereafter, to the payment to or upon the order of such Loan Party or to
whosoever may be lawfully entitled to receive the same or as a court of competent
jurisdiction may direct.

     2.5 Use of Proceeds.

     The proceeds of any Revolving Loans shall be applied by Company for working capital and other
general corporate purposes, which may include the making of intercompany loans to and equity
Investments in any of Company’s wholly-owned Subsidiaries, in each case in accordance with
subsection 9.3, for their own general corporate purposes.

     2.6 Increased Costs; Taxes; Capital Adequacy; Change in Law; Illegality.

 (First Amended and Restated Credit Agreement)

 - 52 -

 

     A. Taxes. Company shall make all payments required hereunder, whether by way of principal,
interest or otherwise, without regard to any defense, counterclaim or right of set-off available to
Company and without withholding any Taxes (for the purposes of this subclause 2.6A, “Taxes” shall
not include Taxes on such Lender’s overall income, and franchise taxes). If Company is required by
Applicable Law to deduct any withholding Taxes from or in respect of any amounts payable under this
Agreement (i) the amounts payable by Company hereunder will be increased by the amount necessary so
that after making all required deductions (including deductions applicable to additional sums
payable under this Section 2.6A) Administrative Agent and the Lenders will receive an amount equal
to the sum they would have received had no such deductions been made, (ii) Company will make such
deductions, and (iii) Company will pay the full amount deducted to the relevant taxing authority or
other Governmental Authority in accordance with Applicable Law. Notwithstanding the foregoing,
unless a Person becomes a Lender as a result of an assignment of Loans at a time when an Event of
Default has occurred and is continuing, Company shall have no obligation to gross-up for Taxes
withheld or paid solely because such Lender is a non-resident of Canada within the meaning of the
Income Tax Act, unless Company otherwise agrees in writing to do so.

     B. Capital Adequacy Adjustment. If any Lender shall have determined, acting reasonably, that
the adoption, effectiveness, phase-in or applicability after the date hereof of any law, rule or
regulation (or any provision thereof) regarding capital adequacy, or any change therein or in the
interpretation or administration thereof by any Governmental Authority charged with the
interpretation or administration thereof, or compliance by any Lender with any guideline, request
or directive regarding capital adequacy (whether or not having the force of law) of any such
Governmental Authority, has or would have the effect of reducing the rate of return on the capital
of such Lender or any corporation controlling such Lender as a consequence of, or with reference
to, such Lender’s Loans or Revolving Loan Commitments or Letters of Credit or participations
therein or other obligations hereunder with respect to the Loans or the Letters of Credit to a
level below that which such Lender or such controlling corporation could have achieved but for such
adoption, effectiveness, phase-in, applicability, change or compliance (taking into consideration
the policies of such Lender or such controlling corporation with regard to capital adequacy), then
from time to time, within 10 Business Days after receipt by Company from such Lender of the
statement referred to in Section 2.7A, Company shall pay to such Lender such additional amount or
amounts as will compensate such Lender or such controlling corporation on an after-tax basis for
such reduction.

     C. Market for Bankers’ Acceptances. In the event that at any time subsequent to the giving of
a Notice of Borrowing or Notice of Conversion/Rollover to Administrative Agent by Company with
regard to any requested Bankers’ Acceptances, but before the date of the borrowing, Rollover or
Conversion, as the case may be, the Administrative Agent makes a determination, which shall be
conclusive and binding upon Company, absent manifest error, that there no longer exists an active
market for Bankers’ Acceptances then:

     (i) the right of Company to request Bankers’ Acceptances or BA Equivalent Advances from
any Lender shall be suspended until Administrative Agent determines that the circumstances
causing such suspension no longer exist, and so notifies Company;

 (First Amended and Restated Credit Agreement)

 - 53 -

 

     (ii) any outstanding Notice of Borrowing requesting a Loan by way of Bankers’
Acceptances or BA Equivalent Advances shall (unless revoked by Company before the Funding
Date) be deemed to be a Notice of Borrowing requesting a Loan by way of Prime Rate Loans in
the amount specified in the original Notice of Borrowing;

     (iii) any outstanding Notice of Conversion/Rollover requesting a Conversion of a Prime
Rate Loan into Bankers’ Acceptances or BA Equivalent Advances shall be deemed to be revoked;
and

     (iv) any outstanding Notice of Conversion/Rollover requesting a Rollover of Bankers’
Acceptances or BA Equivalent Advances shall (unless revoked by Company before the Funding
Date) be deemed to be a Notice of Conversion/Rollover requesting a Conversion of such Loans
into Prime Rate Loans.

The Agent shall promptly notify Company and the Lenders of any suspension of Company’s right to
request Bankers’ Acceptances or BA Equivalent Advances and of any termination of any such
suspension.

     D. Change in Law. If, after the date hereof, the adoption of any Applicable Law, regulation,
treaty or official directive (whether or not having the force of law) or any change therein or in
the interpretation or application thereof by any court or by any Governmental Authority or any
other entity charged with the interpretation or administration thereof or compliance by a Lender
with any request or direction (whether or not having the force of law) of any such authority or
entity hereafter:

     (i) subjects such Lender to, or causes the withdrawal or termination of a previously
granted exemption with respect to, any Taxes (for the purposes of this subclause 2.6D,
“Taxes” shall not include Taxes on such Lender’s overall income, and franchise taxes), or
changes the basis of taxation of payments due to such Lender, or increases any existing
Taxes on payments of principal, interest or other amounts payable by Company to such Lender
under this Agreement;

     (ii) imposes, modifies or deems applicable any reserve, liquidity, special deposit,
regulatory or similar requirement against assets or liabilities held by, or deposits in or
for the account of, or loans by such Lender, or any acquisition of funds for loans or
commitments to fund loans or obligations in respect of undrawn, committed lines of credit or
in respect of Bankers’ Acceptances accepted by such Lender;

     (iii) imposes on such Lender or requires there to be maintained by such Lender any
capital adequacy or additional capital requirements (including a requirement which affects
such Lender’s allocation of capital resources to its obligations) in respect of any Loan,
Letter of Credit or obligation of such Lender hereunder, or any other condition with respect
to this Agreement; or

     (iv) directly or indirectly affects the cost to such Lender of making available,
funding or maintaining any Loan, or issuing or participating in any Letter of Credit or

 (First Amended and Restated Credit Agreement)

 - 54 -

 

otherwise imposes on such Lender any other condition or requirement affecting this
Agreement or any Loan or any obligation of such Lender hereunder;

and the result of (i), (ii), (iii) or (iv) above, in the sole determination of such Lender acting
in good faith, is:

(a) to increase the cost to such Lender of performing its obligations
hereunder with respect to any Loan or Letter of Credit;

(b) to reduce any amount received or receivable by such Lender hereunder or
its effective return hereunder or on its capital in respect of any Loan,
Letter of Credit or any Revolving Loan Commitment; or

(c) to cause such Lender to make any payment with respect to or to forego
any return on or calculated by reference to, any amount received or
receivable by such Lender hereunder with respect to any Loan, Letter of
Credit or any Revolving Loan Commitment;

such Lender shall determine that amount of money which shall compensate the Lender for such
increase in cost, payments to be made or reduction in income or return or interest foregone (herein
referred to as “Additional Compensation”). Upon a Lender having determined that it is entitled to
Additional Compensation in accordance with the provisions of this Section, the Lender shall
promptly so notify Company and Administrative Agent. The relevant Lender shall provide Company and
Administrative Agent with a photocopy of the relevant law, rule, guideline, regulation, treaty or
official directive (or, if it is impracticable to provide a photocopy, a written summary of the
same) and a certificate of a duly authorized officer of such Lender setting forth the Additional
Compensation and the basis of calculation therefor, which shall be conclusive evidence of such
Additional Compensation in the absence of manifest error. Company shall pay to such Lender within
10 Business Days of the giving of such notice such Lender’s Additional Compensation. Each of the
Lenders shall be entitled to be paid such Additional Compensation from time to time to the extent
that the provisions of this Section are then applicable notwithstanding that any Lender has
previously been paid any Additional Compensation.

     2.7 Statement of Lenders; Obligation of Lenders to Mitigate.

     A. Statements. Each Lender, Issuing Lender or Agent claiming compensation or reimbursement
pursuant to subsection 2.6 or 2.7B shall deliver to Company (with a copy to Administrative Agent) a
written statement, setting forth in reasonable detail the basis of the calculation of such
compensation or reimbursement, which statement shall be conclusive and binding upon all parties
hereto absent manifest error.

     B. Mitigation. Each Lender, Issuing Lender and Agent agrees that, as promptly as practicable
after the officer of such Person responsible for administering the Loans or Letters of Credit of
such Person, as the case may be, becomes aware of the occurrence of an event or the existence of a
condition that would entitle such Person to receive payments under subsections 2.6

 (First Amended and Restated Credit Agreement)

 - 55 -

 

or 2.9, use reasonable efforts to make, issue, fund or maintain the Commitments, Loans or
Letters of Credit, as applicable, of such Person through another lending or letter of credit office
of such Person, if (i) as a result thereof the additional amounts which would otherwise be required
to be paid to such Person pursuant to subsection 2.6 or 2.9 would be materially reduced, and (ii)
as determined by Person, acting reasonably, such action would not otherwise be disadvantageous to
such Person; provided that such Person will not be obligated to utilize such other lending
or letter of credit office pursuant to this subclause 2.7B unless Company agrees to pay all
incremental expenses incurred by such Person as a result of utilizing such other lending or letter
of credit office in connection with such Loans or Letters of Credit as described above.

     2.8 Replacement of a Lender.

          If Company receives a statement of amounts due pursuant to subsection 2.7A from a Lender, a
Revolving Lender defaults in its obligations to fund a Revolving Loan pursuant to this Agreement, a
Lender (a “Non-Consenting Lender”) refuses to consent to an amendment, modification or waiver of
this Agreement that, pursuant to subsection 12.6, requires consent of 100% of the Lenders or 100%
of the Lenders with Obligations directly affected, or a Lender has, pursuant to subsection 2.9,
declared its obligations under this Agreement with respect to certain Loans to be terminated (any
such Lender, a “Subject Lender”), so long as (i) no Potential Event of Default or Event of Default
shall have occurred and be continuing and Company has obtained a commitment from another Lender or
an Eligible Assignee to purchase at par the Subject Lender’s Loans and assume the Subject Lender’s
Revolving Loan Commitments and all other obligations of the Subject Lender hereunder, (ii) such
Lender is not an Issuing Lender with respect to any Letters of Credit outstanding (unless all such
Letters of Credit are terminated or arrangements acceptable to such Issuing Lender (such as a
“back-to-back” letter of credit) are made) and (iii), if applicable, the Subject Lender is
unwilling to withdraw the notice delivered to Company pursuant to subsection 2.7 and/or is
unwilling to remedy its default upon 10 days prior written notice to the Subject Lender and
Administrative Agent and/or is unwilling to approve the applicable amendment, modification or
waiver upon 5 days prior written notice to the Subject Lender and Administrative Agent, Company may
require the Subject Lender to assign all of its Loans and Revolving Loan Commitments to such other
Lender, Lenders, Eligible Assignee or Eligible Assignees pursuant to the provisions of subsection
12.1B, provided that, prior to or concurrently with such replacement, (1) the Subject
Lender shall have received payment in full of all principal, interest, fees and other amounts
(including all amounts under subsections 2.6 and/or 2.7B (if applicable)) owed to it through such
date of replacement and a release from its obligations under the Loan Documents, (2) the processing
fee required to be paid by subsection 12.1B(i) shall have been paid to Administrative Agent, (3)
all of the requirements for such assignment contained in subsection 12.1B including the consent of
Administrative Agent (if required) and the receipt by Administrative Agent of an executed
Assignment Agreement and other supporting documents, have been fulfilled, and (4) in the event such
Subject Lender is a Non-Consenting Lender, each assignee shall consent, at the time of such
assignment, to each matter in respect of which such Subject Lender was a Non-Consenting Lender and
Company also requires each other Subject Lender that is a Non-Consenting Lender to assign its Loans
and Revolving Loan Commitments.

     2.9 Illegality.

(First Amended and Restated Credit Agreement)

 - 56 -

 

          If a Lender determines, in good faith, that the adoption of any Applicable Law, regulation,
treaty or official directive (whether or not having the force of law) or any change therein or in
the interpretation or application thereof by any court or by any Governmental Authority or any
other entity charged with the interpretation or administration thereof or compliance by a Lender
with any request or direction (whether or not having the force of law) of any such authority or
entity, now or hereafter makes it unlawful or impossible for any Lender to make, fund or maintain a
Loan, issue a Letter of Credit or maintain a Revolving Loan Commitment, or to give effect to its
obligations in respect of such a Loan, Revolving Loan Commitment or a Letter of Credit, such Lender
may, by written notice thereof to Company and to Administrative Agent (which shall include in
reasonable detail an explanation of its determination) declare its obligations under this Agreement
in respect of such Loan, Letter of Credit or Revolving Loan Commitment to be terminated whereupon
the same shall, subject to subsection 2.7B, forthwith terminate, and Company shall, subject to
subsection 2.7B, within the time required by such law (or at the end of such longer period as such
Lender at its discretion has agreed), either effect a Conversion of such Loan in accordance with
the provisions hereof (if such Conversion would resolve the unlawfulness or impossibility) or
prepay the principal of such Loan, and collateralize such Letter of Credit, and pay accrued
interest, such Additional Compensation as may be applicable with respect to such Loan to the date
of such payment. If any such change shall only affect a portion of such Lender’s obligations under
this Agreement which is, in the opinion of such Lender and Administrative Agent, severable from the
remainder of this Agreement so that the remainder of this Agreement may be continued in full force
and effect without otherwise affecting any of the obligations of Administrative Agent, the other
Lenders or Company hereunder, such Lender shall only declare its obligations under that portion so
terminated.

Section 3. BANKERS’ ACCEPTANCES

     3.1 Acceptance of Bankers’ Acceptances; Form and Execution.

     A. Bankers’ Acceptances. Pursuant to subsection 2.1A, Company may request, in accordance with
the provisions of this subsection 3.1, from time to time during the period from the Restatement
Date to but excluding the 30th day prior to the Revolving Loan Commitment Termination
Date that the Lenders accept Bankers’ Acceptances issued by Company or make BA Equivalent Advances
to Company. Subject to the terms and conditions of this Agreement and in reliance upon the
representations and warranties of Company herein set forth, such Lenders shall accept such Bankers’
Acceptances, or make BA Equivalent Advances in lieu thereof, in accordance with the provisions of
this subsection 3.1, provided that Company shall not request that any Lender having a
Revolving Loan Commitment accept such Bankers’ Acceptances, or make BA Equivalent Advances (and no
Lender shall do so) if, after giving effect to such issuance a Bankers’ Acceptance or BA Equivalent
Advance would have a term ending later than the Revolving Loan Commitment Termination Date.

     B. Applicable Provisions. The following provisions shall apply to each Bankers’ Acceptance
hereunder:

 (First Amended and Restated Credit Agreement)

 - 57 -

 

     (i) the face amount at maturity of each draft drawn by Company to be accepted as a
Bankers’ Acceptance shall be Cdn. $100,000 and integral multiples thereof;

     (ii) each draft drawn by Company and presented for acceptance by a Lender shall be
drawn on the standard form of such Lender in effect at the time, specifying the BA Interest
Period, provided that Administrative Agent may require the Lenders to use a generic
form of Bankers’ Acceptance, in a form satisfactory to each Lender, acting reasonably,
provided by Administrative Agent for such purpose in place of the Lenders’ own forms;

     (iii) subject to subparagraph 3.1B(iv), Bankers’ Acceptances shall be signed by duly
authorized officers of Company or, in the alternative, the signatures of such officers may
be mechanically reproduced in facsimile thereon and Bankers’ Acceptances bearing such
facsimile signatures shall be binding on Company as if they had been manually executed and
delivered by such officers on behalf of Company. Notwithstanding that any person whose
manual or facsimile signature appears on any Bankers’ Acceptance may no longer be an
authorized signatory for Company on the date of issuance of a Bankers’ Acceptance, such
signature shall nevertheless be valid and sufficient for all purposes as if such authority
had remained in force at the time of such issuance and any such Bankers’ Acceptance shall be
binding on Company; and

     (iv) in lieu of Company signing Bankers’ Acceptances in accordance with subparagraph
3.1B(iii), and, for so long as the power of attorney in subparagraph 3.2A is in force with
respect to a given Lender, such Lender shall execute and deliver Bankers’ Acceptances on
behalf of Company in accordance with the provisions thereof and, for certainty, all
references herein to drafts drawn by Company, Bankers’ Acceptances executed by Company or
similar expressions shall be deemed to include Bankers’ Acceptances executed in accordance
with a power of attorney, unless the context otherwise requires.

          If and for so long as the power of attorney referred to in subsection 3.2A is in force with
respect to each Lender, it is intended that pursuant to the DBNA, all Bankers’ Acceptances accepted
by the Lenders (other than Old System Issuers) under this Agreement will be issued in the form of a
“depository bill” (as defined in the DBNA), and deposited with a Clearing House. In order to give
effect to the foregoing, Administrative Agent will, subject to the approval of Company and the
Lenders (other than Old System Issuers), establish and notify Company and the Lenders of any
additional procedures, consistent with the terms of this Agreement and the DBNA, as are reasonably
necessary to accomplish such intention, including:

     (a) any instrument held by Administrative Agent for the purposes of Bankers’
Acceptances will 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)”;

     (b) any reference to the authentication of the Bankers’ Acceptance will be
removed; and

 (First Amended and Restated Credit Agreement)

 - 58 -

 

     (c) any reference to the “bearer” will be removed and such Bankers’ Acceptances
will not be marked with any words prohibiting negotiation, transfer or assignment of
it or of an interest in it.

     3.2 Power of Attorney; Provision of Bankers’ Acceptances to Lenders.

     A. Power of Attorney. As a condition precedent to each Lender’s obligation to accept Bankers’
Acceptances hereunder, Company hereby appoints each Lender, acting by any authorized signatory of
the Lender in question, the attorney of Company:

     (i) to sign for and on behalf and in the name of Company as drawer, drafts in such
Lender’s standard form which are depository bills as defined in the DBNA, payable to a
Clearing House ;

     (ii) for drafts which are not depository bills, to sign for and on behalf and in the
name of Company as drawer and to endorse on its behalf, Bankers’ Acceptances drawn on the
Lender payable to the order of such Lender;

     (iii) for BA Discount Notes, to sign for and on behalf and in the name of Company as
drawer and to endorse on its behalf BA Discount Notes payable to the order of such Lender;

     (iv) to fill in the amount, date and maturity date of such Bankers’ Acceptances (or BA
Discount Notes as applicable); and

     (v) to deposit and/or deliver such Bankers’ Acceptances which have been accepted by
such Lender or such BA Discount Notes which are payable to the order of such Lender,

provided that such acts in each case are to be undertaken by the Lender in question
strictly in accordance with instructions given to such Lender by Company as provided in this
Section. For certainty, signatures of any authorized signatory of a Lender may be mechanically
reproduced in facsimile on Bankers’ Acceptances (or BA Discount Notes as applicable) in accordance
herewith and such facsimile signatures shall be binding and effective as if they had been manually
executed by such authorized signatory of such Lender.

          Instructions from Company to a Lender relating to the execution, completion, endorsement,
deposit and/or delivery by that Lender on behalf of Company of Bankers’ Acceptances (or BA Discount
Notes as applicable) which Company wishes to submit to the Lender for acceptance by the Lender
shall be communicated by Company in writing to Administrative Agent by delivery to Administrative
Agent of Notices of Borrowing and Notices of Conversion/ Rollover, as the case may be, in
accordance with this Agreement which, in turn, shall be communicated by Administrative Agent, on
behalf of Company, to the Lender.

          The communication in writing by Company, or on behalf of Company by Administrative Agent, to
the Lender of the instructions set out in the Notices of Borrowing and

 (First Amended and Restated Credit Agreement)

 - 59 -

 

Notice of Conversion/Rollover Notices referred to above shall constitute (a) the authorization
and instruction of Company to the Lender to sign for and on behalf and in the name of Company as
drawer the requested Bankers’ Acceptances (or BA Discount Notes as applicable) and to complete
and/or endorse Bankers’ Acceptances (or BA Discount Notes as applicable) in accordance with such
information as set out above, and (b) the request of Company to the Lender to accept such Bankers’
Acceptances and deposit the same with a Clearing House or deliver the same, as the case may be, in
each case in accordance with this Agreement and such instructions. Company acknowledges that a
Lender shall not be obligated to accept any such Bankers’ Acceptances except in accordance with the
provisions of this Agreement.

          A Lender shall be and it is hereby authorized to act on behalf of Company upon and in
compliance with instructions communicated to that Lender as provided herein if the Lender
reasonably believes such instructions to be genuine. If a Lender accepts Bankers’ Acceptances
pursuant to any such instructions, that Lender shall confirm particulars of such instructions and
advise Administrative Agent that it has complied therewith by notice in writing to Administrative
Agent in accordance with the provisions hereof. A Lender’s actions in compliance with such
instructions, confirmed and advised to Administrative Agent by such notice, shall be prima facie
evidence of having been in accordance with the instructions of Company.

     B. Revocation. The power of attorney in subsection 3.2A may be revoked by Company with
respect to any particular Lender at any time upon not less than 5 Business Days’ prior written
notice served upon the Lender in question and Administrative Agent, provided that no such
revocation shall reduce, limit or otherwise affect the obligations of Company in respect of any
Bankers’ Acceptance (or BA Discount Note as applicable) executed, completed, endorsed, deposited
and/or delivered in accordance herewith prior to the time at which such revocation becomes
effective. If the power of attorney is so revoked with respect to any Lender, Company shall, from
time to time as required by the applicable Lenders, provide to Administrative Agent for delivery to
each such Lender drafts drawn in blank by Company (pre-endorsed and otherwise in fully negotiable
form, if applicable) in quantities sufficient for each such Lender to fulfill its obligations
hereunder. Any such pre-signed drafts which are delivered by Company to Administrative Agent or a
Lender shall be held in safekeeping by Administrative Agent or such Lender, as the case may be,
with the same degree of care as if they were Administrative Agent’s or such Lender’s property, and
shall only be dealt with by the Lenders and Administrative Agent in accordance herewith. No Lender
shall be responsible or liable for its failure to make its share of any Bankers’ Acceptances
required hereunder if the cause of such failure is, in whole or in part, due to the failure of
Company to provide such pre-signed drafts to Administrative Agent (for delivery to such Lender) on
a timely basis.

     C. Delivery of Drafts. By 11:00 a.m. (Toronto time) on the applicable Funding Date,
Conversion or Rollover date, Company shall (i) either deliver to each Lender in Toronto, or, if
previously delivered, be deemed to have authorized each Lender to complete and accept, or (ii)
where the power of attorney in Section 3.2A is in force with respect to a Lender, be deemed to have
authorized each such Lender to sign on behalf of Company, complete and accept, drafts drawn by
Company on such Lender in a principal amount at maturity equal to such Lender’s share of the
Bankers’ Acceptances specified by Company in the relevant Notice of Borrowing or

 (First Amended and Restated Credit Agreement)

 - 60 -

 

Notice of Conversion/Rollover, as the case may be, as notified to the Lenders by
Administrative Agent.

     3.3 Mechanics of Issuance.

     A. Apportionment. Upon receipt by Administrative Agent of a Notice of Borrowing or Notice of
Conversion/Rollover from Company requesting the issuance of Bankers’ Acceptances, Administrative
Agent shall promptly notify the Lenders thereof and advise each Lender of the aggregate face amount
of Bankers’ Acceptances to be accepted and purchased by such Lender, the date of issue and the BA
Interest Period for such Loan; the apportionment among the Lenders of the face amounts of Bankers’
Acceptances to be accepted by each Lender shall be determined by Administrative Agent by reference
and in proportion to the respective applicable Revolving Loan Commitments of each Lender,
provided that, when such apportionment cannot be evenly made, Administrative Agent shall
round allocations amongst such Lenders consistent with Administrative Agent’s normal money market
practices.

     B. Rate Determination. On each date for borrowing, Rollover or Conversion involving the
issuance of Bankers’ Acceptances:

     (i) on or about 11:00 a.m. (Toronto time) on such date, Administrative Agent shall
determine the CDOR Rate and shall obtain quotations from the Schedule II Reference Lenders
in order to determine the BA Discount Rate then applicable to Bankers’ Acceptances accepted
by such Schedule II Lender and Schedule III Lender in respect of an issue of Bankers’
Acceptances in a comparable amount and with comparable maturity to the Bankers’ Acceptances
proposed to be issued on such date;

     (ii) on or about 11:00 a.m. (Toronto time) on such date, Administrative Agent shall
determine the BA Discount Rate applicable to each Lender and shall advise each Lender of the
BA Discount Rate applicable to it;

     (iii) each Lender shall complete and accept, in accordance with the Notice of Borrowing
or Notice of Conversion/Rollover delivered by Company and advised by Administrative Agent in
connection with such issue, its share of the Bankers’ Acceptances to be issued on such date
and shall purchase such Bankers’ Acceptances for its own account at a purchase price which
reflects the BA Discount Rate applicable to such issue; and

     (iv) in the case of a borrowing, each Lender shall, for same day value on the Funding
Date, remit the BA Discount Proceeds or advance the BA Equivalent Advance, as the case may
be, payable by such Lender (net of the stamping fee payable to such Lender pursuant to
Section 3.9) to Administrative Agent for the account of Company; Administrative Agent shall
make such funds available to Company for same day value on such date.

 (First Amended and Restated Credit Agreement)

 - 61 -

 

     C. Resale. Each Lender may at any time and from time to time hold, sell, rediscount or
otherwise dispose of any or all Bankers’ Acceptances accepted and purchased by it for its own
account.

     3.4 Rollover of Bankers’ Acceptances.

          In order to satisfy the liability of Company to a Lender for the face amount of maturing
Bankers’ Acceptances accepted by such Lender, such Lender shall receive and retain for its own
account the BA Discount Proceeds of new Bankers’ Acceptances issued on a Rollover, and Company
shall on the maturity date of the Bankers’ Acceptances being rolled over pay to Administrative
Agent for the account of the Lenders an amount equal to the difference between the face amount of
the maturing Bankers’ Acceptances and the BA Discount Proceeds from the new Bankers’ Acceptances,
together with the stamping fees to which the Lenders are entitled pursuant to Section 3.9.

     3.5 Conversion into Bankers’ Acceptances.

          In respect of Conversions into Bankers’ Acceptances, in order to satisfy the liability of
Company to the Lenders for the amount of the converted Loan, each Lender shall receive and retain
for its own account the BA Discount Proceeds of the Bankers’ Acceptances issued upon such
Conversion, and Company shall on the date for Conversion pay to Administrative Agent for the
account of the Lenders an amount equal to the difference between the principal amount of the
converted Loan and the aggregate BA Discount Proceeds from the Bankers’ Acceptances issued on such
Conversion, together with the stamping fees to which the Lenders are entitled pursuant to Section
3.9.

     3.6 Conversion from Bankers’ Acceptances.

          In order to satisfy the liability of Company to the Lenders for an amount equal to the
aggregate face amount of the maturing Bankers’ Acceptances converted to another type of Loan,
Administrative Agent shall record the obligation of Company to the Lenders as a Loan of the type
into which such continuing liability has been converted.

     3.7 BA Equivalent Advances.

          Notwithstanding the foregoing provisions of this Article, a Non-Acceptance Lender shall, in
lieu of accepting Bankers’ Acceptances, make a BA Equivalent Advance. The amount of each BA
Equivalent Advance shall be equal to the BA Discount Proceeds which would be realized from a
hypothetical sale of those Bankers’ Acceptances which, but for this Section, such Lender would
otherwise be required to accept as part of such a borrowing, Conversion or Rollover of Bankers’
Acceptances. To determine the amount of such BA Discount Proceeds, the hypothetical sale shall be
deemed to take place at the BA Discount Rate for such Loan. Any BA Equivalent Advance shall be made
on the relevant Funding Date, or Rollover or Conversion date as the case may be and shall remain
outstanding for the term of the relevant Bankers’ Acceptances. Concurrent with the making of a BA
Equivalent Advance, a Non-Acceptance Lender shall be entitled to deduct therefrom an amount equal
to the stamping fee
 (First Amended and Restated Credit Agreement)

 - 62 -

 

which, but for this Section, such Lender would otherwise be entitled to receive as part of
such Loan. Upon the maturity date for such Bankers’ Acceptances, Company shall pay to each
Non-Acceptance Lender an amount equal to the face amount of the Bankers’ Acceptances which such
Lender would have accepted as part of such Loan if it was not a Non-Acceptance Lender.

          All references herein to “Loans” and “Bankers’ Acceptances” shall, unless otherwise expressly
provided herein or unless the context otherwise requires, be deemed to include BA Equivalent
Advances made by a Non-Acceptance Lender as part of a borrowing, Conversion or Rollover of Bankers’
Acceptances.

     3.8 Termination of Bankers’ Acceptances.

          If at any time a Lender ceases to accept Bankers’ Acceptances in the ordinary course of its
business, such Lender shall be deemed to be a Non-Acceptance Lender and shall make BA Equivalent
Advances in lieu of accepting Bankers’ Acceptances under this Agreement.

     3.9 Stamping Fees.

          Upon the acceptance by a Lender of a Bankers’ Acceptance, Company shall pay to Administrative
Agent for the account of such Lender a stamping fee in Cdn. Dollars equal to 3.0% per annum
calculated on the principal amount at maturity of such Bankers’ Acceptance and BA Equivalent
Advances and for the period of time from and including the date of acceptance or advance to but
excluding the maturity date of such Bankers’ Acceptance or BA Equivalent Advance and calculated on
the basis of the number of days elapsed in a year of 365 days.

     3.10 No Issuance, Conversion or Rollover during Default.

          Notwithstanding the foregoing provisions of this Section 3, no Bankers’ Acceptance may be
accepted, no BA Equivalent Advances may be made, no Prime Rate Loan may be subject to a Conversion
into a Bankers’ Acceptance or BA Equivalent Advance and no Banker’s Acceptance or BA Equivalent
Advance shall be subject to a Rollover after the occurrence and during the continuation of a
Potential Event of Default or an Event of Default. After the occurrence and during the
continuation of an Event of Default, outstanding Bankers’ Acceptances and BA Equivalent Advances
shall convert to Prime Rate Loans at the end of the BA Interest Period applicable thereto.

Section 4. LETTERS OF CREDIT

     4.1 Issuance of Letters of Credit and Lenders’ Purchase of Participations Therein.

     A. Letters of Credit. In addition to Company requesting that Lenders make Loans by way of
Prime Rate Loans and Bankers’ Acceptances pursuant to subsection 2.1A, Company may request, in
accordance with the provisions of this subsection 4.1, from time to time during the period from the
Restatement Date to but excluding the 30th day prior to the Revolving Loan Commitment
Termination Date, that a Revolving Lender issue Letters of Credit for the account

 (First Amended and Restated Credit Agreement)

 - 63 -

 

of Company for the purposes specified in the definition of Letters of Credit. Subject to the
terms and conditions of this Agreement and in reliance upon the representations and warranties of
Company herein set forth, any Lender may, but (except as provided in subsection 4.1B(ii) in respect
of the Fronting Bank) shall not be obligated to, issue such Letters of Credit in accordance with
the provisions of this subsection 4.1, provided that Company shall not request that any
Revolving Lender issue (and no Revolving Lender shall issue):

     (i) any Letter of Credit having an expiration date later than the earlier of (a) 10
days prior to the Revolving Loan Commitment Termination Date and (b) the date which is one
year from the date of issuance of such Letter of Credit, provided that the
immediately preceding clause (b) shall not prevent any Issuing Lender from agreeing that a
Letter of Credit will automatically be extended for one or more successive periods not to
exceed one year each unless such Issuing Lender elects not to extend for any such additional
period; and provided further that such Issuing Lender shall not extend such
Letter of Credit if it has knowledge that an Event of Default has occurred and is continuing
(and has not been waived in accordance with subsection 12.6) at the time such Issuing Lender
must elect whether or not to allow such extension; or

     (ii) any Letter of Credit issued for the purpose of supporting trade payables or
indebtedness for borrowed money.

     For the avoidance of doubt, as of the Restatement Date, each of the Existing Letters of Credit
shall be deemed to be a Letter of Credit issued and outstanding under this Agreement.

     B. Mechanics of Issuance.

     (i) Request for Issuance. Whenever Company desires the issuance of a Letter of
Credit, it shall deliver to Administrative Agent and the Fronting Bank a Request for
Issuance no later than 12:00 noon (Toronto time) at least three Business Days, or such
shorter period as may be agreed to by the Issuing Lender in any particular instance, in
advance of the proposed date of issuance. The Issuing Lender, in its reasonable discretion,
may require changes in the text of the proposed Letter of Credit or any documents described
in or attached to the Request for Issuance, and may require an application and/or indemnity
of Company in such Issuing Lender’s customary form. In furtherance of the provisions of
subsection 12.8, and not in limitation thereof, Company may submit Requests for Issuance by
telefacsimile, and Administrative Agent and Issuing Lenders may rely and act upon any such
Request for Issuance without receiving an original signed copy thereof. Unless the Issuing
Lender otherwise agrees, no Letter of Credit shall require payment against a conforming
demand for payment to be made thereunder on the same business day (under the laws of the
jurisdiction in which the office of the Issuing Lender to which such demand for payment is
required to be presented is located) that such demand for payment is presented if such
presentation is made after 1:00 p.m. (in the time zone of such office of the Issuing Lender)
on such business day.

 (First Amended and Restated Credit Agreement)

 - 64 -

 

          Company shall notify the applicable Issuing Lender (and Administrative Agent, if
Administrative Agent is not such Issuing Lender) prior to the issuance of any Letter of
Credit in the event that any of the matters to which Company is required to certify in the
applicable Request for Issuance is no longer true and correct as of the proposed date of
issuance of such Letter of Credit, and upon the issuance of any Letter of Credit, Company
shall be deemed to have re-certified, as of the date of such issuance, as to the matters to
which Company is required to certify in the applicable Request for Issuance.

     (ii) Determination of Issuing Lender. Upon receipt by Administrative Agent of
a Request for Issuance pursuant to subsection 4.1B(i) requesting the issuance of a Letter of
Credit, in the event Fronting Bank elects to issue such Letter of Credit, Administrative
Agent shall promptly so notify Company, and Fronting Bank shall be the Issuing Lender with
respect thereto. In the event that Fronting Bank, in its sole discretion, elects not to
issue such Letter of Credit, Fronting Bank shall promptly so notify Company and
Administrative Agent, whereupon Company may request any other Revolving Lender to issue such
Letter of Credit by delivering to such Revolving Lender a copy of the applicable Request for
Issuance. Any Revolving Lender so requested to issue such Letter of Credit shall promptly
notify Company, Fronting Bank and Administrative Agent whether or not, in its sole
discretion, it has elected to issue such Letter of Credit, and any such Revolving Lender
that so elects to issue such Letter of Credit shall be the Issuing Lender with respect
thereto, provided that if more than one Revolving Lender so elects to issue such
Letter of Credit, Company shall determine which Revolving Lender shall be the Issuing
Lender.

          In the event that all other Revolving Lenders shall have declined to issue such Letter
of Credit, notwithstanding the prior election of Fronting Bank not to issue such Letter of
Credit, Fronting Bank shall be obligated to issue such Letter of Credit and shall be the
Issuing Lender with respect thereto, notwithstanding the fact that the Letter of Credit
Usage with respect to such Letter of Credit and with respect to all other Letters of Credit
issued by Fronting Bank, when aggregated with Fronting Bank’s outstanding Revolving Loans,
may exceed Fronting Bank’s Revolving Loan Commitment then in effect. If Fronting Bank has
resigned as provided in subclause 11.5C and no successor Fronting Bank has been appointed at
the time of a Request for Issuance, then, unless prior to the issuance the Company withdraws
its Request for Issuance, each Revolving Lender shall issue or cause to be issued a Letter
of Credit as to its own Pro Rata Share of each requested Letter of Credit, all of which
taken together would aggregate the amount requested in the Request for Issuance.

     (iii) Issuance of Letter of Credit. Upon satisfaction or waiver (in accordance
with subsection 12.6) of the conditions set forth in subsection 6.3, the Issuing Lender
shall issue the requested Letter of Credit in accordance with the Issuing Lender’s standard
operating procedures.

     (iv) Notification to Revolving Lenders. Upon the issuance of or amendment to
any Letter of Credit, the applicable Issuing Lender shall promptly notify Administrative

 (First Amended and Restated Credit Agreement)

 - 65 -

 

Agent and Company of such issuance or amendment in writing and such notice shall be
accompanied by a copy of such Letter of Credit or amendment. Upon receipt of such notice
(or, if Administrative Agent is the Issuing Lender, together with such notice),
Administrative Agent shall notify each Revolving Lender in writing of such issuance or
amendment and the amount of such Revolving Lender’s respective participation in such Letter
of Credit or amendment, and, if so requested by a Revolving Lender, Administrative Agent
shall provide such Lender with a copy of such Letter of Credit or amendment.

     C. Revolving Lenders’ Purchase of Participations in Letters of Credit. Immediately upon the
issuance of each Letter of Credit, each Revolving Lender shall be deemed to, and hereby agrees to,
have irrevocably purchased from the Issuing Lender a participation in such Letter of Credit and any
drawings honored thereunder in an amount equal to such Revolving Lender’s Pro Rata Share of the
maximum amount that is or at any time may become available to be drawn thereunder.

     4.2 Letter of Credit Fees.

          Company agrees to pay the following amounts with respect to Letters of Credit issued
hereunder:

     (i) with respect to each Letter of Credit, (a) a fronting fee, payable directly to the
applicable Issuing Lender for its own account, equal to the greater of (X) Cdn.$500 and (Y)
0.25% per annum of the daily amount available to be drawn under such Letter of Credit and
(b) a letter of credit fee, payable to Administrative Agent for the account of Revolving
Lenders, equal to 3.0% per annum plus, upon the occurrence and during the
continuance of an Event of Default, 2% per annum, multiplied by the daily amount
available to be drawn under such Letter of Credit, each such fronting fee or letter of
credit fee to be payable quarterly in arrears up to and including each March 31, June 30,
September 30 and December 31 of each year and computed on the basis of a 365-day year for
the actual number of days elapsed, and payable on the first Business Day of the month
immediately following each such quarter;

     (ii) with respect to the issuance, administration, amendment or transfer of each Letter
of Credit and each payment of a drawing made thereunder (without duplication of the fees
payable under clauses (i) and (ii) above), documentary and processing charges payable
directly to the applicable Issuing Lender for its own account in accordance with such
Issuing Lender’s standard schedule for such charges in effect at the time.

For purposes of calculating any fees payable under clauses (i) and (ii) of this subsection 4.2, the
daily amount available to be drawn under any Letter of Credit shall be determined as of the close
of business on any date of determination.

     4.3 Drawings and Reimbursement of Amounts Paid Under Letters of Credit

 (First Amended and Restated Credit Agreement)

 - 66 -

 

     A. Responsibility of Issuing Lender With Respect to Drawings. In determining whether to honor
any drawing under any Letter of Credit by the beneficiary thereof, the Issuing Lender shall be
responsible only to examine the documents delivered under such Letter of Credit with reasonable
care so as to ascertain whether they appear on their face to be in accordance with the terms and
conditions of such Letter of Credit.

     B. Reimbursement by Company of Amounts Paid Under Letters of Credit. In the event an Issuing
Lender has determined to honor a drawing under a Letter of Credit issued by it, such Issuing Lender
shall immediately notify Company and Administrative Agent, and Company shall reimburse such Issuing
Lender on or before the Business Day immediately following the date on which such drawing is
honored (the “Reimbursement Date”) in an amount in Cdn. Dollars and in same day funds equal to the
amount of such payment, provided that, anything contained in this Agreement to the contrary
notwithstanding, unless Company shall have notified Administrative Agent and such Issuing Lender
prior to 11:00 a.m. (Toronto time) on the date such drawing is honored that Company intends to
reimburse such Issuing Lender for the amount of such payment with funds other than the proceeds of
Revolving Loans:

     (i) Company shall be deemed to have given a timely Notice of Borrowing to
Administrative Agent requesting Revolving Lenders to make Revolving Loans that are Prime
Rate Loans on the Reimbursement Date in an amount equal to the amount of such payment, and

     (ii) subject to satisfaction or waiver of the conditions specified in subsection 6.2
(other than 6.2A), Revolving Lenders shall, on the Reimbursement Date, make Revolving Loans
that are Prime Rate Loans in the amount of such payment, the proceeds of which shall be
applied directly by Administrative Agent to reimburse such Issuing Lender for the amount of
such payment;

and provided, further that if for any reason proceeds of Revolving Loans are not
received by such Issuing Lender on the Reimbursement Date in an amount equal to the amount of such
payment, Company shall reimburse such Issuing Lender, on demand, in an amount in same day funds
equal to the excess of the amount of such payment by Issuing Lender over the aggregate amount of
such Revolving Loans, if any, which are so received. Nothing in this subsection 4.3B shall be
deemed to relieve any Revolving Lender from its obligation to make Revolving Loans on the terms and
conditions set forth in this Agreement, and Company shall retain any and all rights it may have
against any Revolving Lender resulting from the failure of such Revolving Lender to make such
Revolving Loans under this subsection 4.3B.

     C. Payment by Lenders of Unreimbursed Amounts Paid Under Letters of Credit.

     (i) Payment by Revolving Lenders. In the event that Company shall fail for any
reason to reimburse any Issuing Lender as provided in subsection 4.3B in an amount equal to
the amount of any payment by such Issuing Lender under a Letter of Credit issued by it, such
Issuing Lender shall promptly notify Administrative Agent, who shall promptly notify each
Revolving Lender of the unreimbursed amount of such honored

 (First Amended and Restated Credit Agreement)

 - 67 -

 

drawing and of such other Revolving Lender’s respective participation therein based on
such Revolving Lender’s Pro Rata Share. Each Revolving Lender (other than such Issuing
Lender) shall make available to Administrative Agent an amount equal to its respective
participation, in Cdn. Dollars, in same day funds, at the Funding and Payment Office, not
later than 12:00 noon (Toronto time) on the first Business Day after the date notified by
Administrative Agent, and Administrative Agent shall make available to such Issuing Lender
in Cdn. Dollars, in same day funds, at the office of such Issuing Lender on such Business
Day the aggregate amount of the payments so received by Administrative Agent. In the event
that any Revolving Lender fails to make available to Administrative Agent on such Business
Day the amount of such Revolving Lender’s participation in such Letter of Credit as provided
in this subsection 4.3C, such Issuing Lender shall be entitled to recover such amount on
demand from such Revolving Lender together with interest thereon at the rate customarily
used by such Issuing Lender for the correction of errors among banks for three Business Days
and thereafter at the Prime Rate. Nothing in this subsection 4.3C shall be deemed to
prejudice the right of Administrative Agent to recover, for the benefit of Revolving
Lenders, from any Issuing Lender any amounts made available to such Issuing Lender pursuant
to this subsection 4.3C in the event that it is determined by the final judgment of a court
of competent jurisdiction that the payment with respect to a Letter of Credit by such
Issuing Lender in respect of which payments were made by Revolving Lenders constituted gross
negligence or willful misconduct on the part of such Issuing Lender.

     (ii) Distribution to Lenders of Reimbursements Received From Company. In the
event any Issuing Lender shall have been reimbursed by other Revolving Lenders pursuant to
subsection 4.3C for all or any portion of any payment by such Issuing Lender under a Letter
of Credit issued by it, and Administrative Agent or such Issuing Lender thereafter receives
any payments from Company in reimbursement of such payment under the Letter of Credit, to
the extent any such payment is received by such Issuing Lender, it shall distribute such
payment to Administrative Agent, and Administrative Agent shall distribute to each other
Revolving Lender that has paid all amounts payable by it under subsection 4.3C with respect
to such payment such Revolving Lender’s Pro Rata Share of all payments subsequently received
by Administrative Agent or by such Issuing Lender from Company. Any such distribution shall
be made to a Revolving Lender at the account specified in subsection 2.4B(iii).

     D. Interest on Amounts Paid Under Letters of Credit.

     (i) Payment of Interest by Company. Company agrees to pay to Administrative
Agent, with respect to payments under any Letters of Credit issued by any Issuing Lender,
interest on the amount paid by such Issuing Lender in respect of each such payment from the
date a drawing is honored to but excluding the date such amount is reimbursed by Company
(including any such reimbursement out of the proceeds of Revolving Loans pursuant to
subsection 4.3B) at a rate equal to (a) for the period from the date such drawing is honored
to but excluding the Reimbursement Date, the rate then in effect under this Agreement with
respect to Revolving Loans that are Prime Rate Loans, and (b) thereafter, a rate which is 2%
per annum in excess of the rate of interest

 (First Amended and Restated Credit Agreement)

 - 68 -

 

otherwise payable under this Agreement with respect to Revolving Loans that are Prime
Rate Loans. Interest payable pursuant to this subsection 4.3D(i) shall be computed on the
basis of a 365-day year for the actual number of days elapsed in the period during which it
accrues and shall be payable on demand or, if no demand is made, on the date on which the
related drawing under a Letter of Credit is reimbursed in full.

     (ii) Distribution of Interest Payments by Administrative Agent. Promptly upon
receipt by Administrative Agent of any payment of interest pursuant to subsection 4.3D(i)
with respect to a payment under a Letter of Credit,

(a) Administrative Agent shall distribute to (x) each Revolving Lender
(including the Revolving Lender that paid such drawing) out of the interest
received by Administrative Agent in respect of the period from the date such
drawing is honored to but excluding the date on which the applicable Issuing
Lender is reimbursed for the amount of such payment (including any such
reimbursement out of the proceeds of Revolving Loans pursuant to subsection
4.3B), the amount that such Revolving Lender would have been entitled to
receive in respect of the letter of credit fee that would have been payable
in respect of such Letter of Credit for such period pursuant to subsection
4.2 if no drawing had been honored under such Letter of Credit, and (y) such
Issuing Lender the amount, if any, remaining after payment of the amounts
applied pursuant to clause (x), and

(b) in the event such Issuing Lender shall have been reimbursed by other
Revolving Lenders pursuant to subsection 4.3C(i) for all or any portion of
such payment, Administrative Agent shall distribute to each Revolving Lender
(including such Issuing Lender) that has paid all amounts payable by it
under subsection 4.3C(i) with respect to such payment such Revolving
Lender’s Pro Rata Share of any interest received by Administrative Agent in
respect of that portion of such payment so made by Revolving Lenders for the
period from the date on which such Issuing Lender was so reimbursed to but
excluding the date on which such portion of such payment is reimbursed by
Company.

Any such distribution shall be made to a Revolving Lender at the account specified in subsection
2.4B(iii).

     4.4 Obligations Absolute.

          The obligation of Company to reimburse each Issuing Lender for payments under the Letters of
Credit issued by it and to repay any Revolving Loans made by Revolving Lenders pursuant to
subsection 4.3B and the obligations of Revolving Lenders under subsection 4.3C(i) shall be
unconditional and irrevocable and shall be paid strictly in accordance with the terms of this
Agreement under all circumstances including any of the following circumstances:

 (First Amended and Restated Credit Agreement)

 - 69 -

 

     (i) any lack of validity or enforceability of any Letter of Credit;

     (ii) the existence of any claim, set-off, defense or other right which Company or any
Lender may have at any time against a beneficiary or any transferee of any Letter of Credit
(or any Persons for whom any such transferee may be acting), any Issuing Lender or other
Revolving Lender or any other Person or, in the case of a Revolving Lender, against Company,
whether in connection with this Agreement, the transactions contemplated herein or any
unrelated transaction (including any underlying transaction between Company or one of its
Subsidiaries and the beneficiary for which any Letter of Credit was procured);

     (iii) any draft or other document presented under any Letter of Credit proving to be
forged, fraudulent, invalid or insufficient in any respect or any statement therein being
untrue or inaccurate in any respect;

     (iv) payment by the applicable Issuing Lender under any Letter of Credit against
presentation of a draft or other document which does not substantially comply with the terms
of such Letter of Credit;

     (v) any adverse change in the business, operations, properties, assets, condition
(financial or otherwise) or prospects of Company or any of its Subsidiaries;

     (vi) any breach of this Agreement or any other Loan Document by any party thereto;

     (vii) any other circumstance or happening whatsoever, whether or not similar to any of
the foregoing; or

     (viii) the fact that an Event of Default or a Potential Event of Default shall have
occurred and be continuing;

provided, in each case, that payment by the applicable Issuing Lender under the applicable
Letter of Credit shall not have constituted gross negligence or willful misconduct of such Issuing
Lender under the circumstances in question (as determined by a final judgment of a court of
competent jurisdiction).

     4.5 Nature of Issuing Lenders’ Duties.

          As between Company and any Issuing Lender, Company assumes all risks of the acts and omissions
of, or misuse of the Letters of Credit issued by such Issuing Lender by, the respective
beneficiaries of such Letters of Credit. In furtherance and not in limitation of the foregoing,
such Issuing Lender shall not be responsible for: (i) the form, validity, sufficiency, accuracy,
genuineness or legal effect of any document submitted by any party in connection with the
application for and issuance of any such Letter of Credit, even if it should in fact prove to be in
any or all respects invalid, insufficient, inaccurate, fraudulent or forged; (ii) the validity or
sufficiency of any instrument transferring or assigning or purporting to transfer or assign any

 (First Amended and Restated Credit Agreement)

 - 70 -

 

such Letter of Credit or the rights or benefits thereunder or proceeds thereof, in whole or in
part, which may prove to be invalid or ineffective for any reason; (iii) failure of the beneficiary
of any such Letter of Credit to comply fully with any conditions required in order to draw upon
such Letter of Credit; (iv) errors, omissions, interruptions or delays in transmission or delivery
of any messages, by mail, cable, telegraph, telex or otherwise, whether or not they be in cipher;
(v) errors in interpretation of technical terms; (vi) any loss or delay in the transmission or
otherwise of any document required in order to make a drawing under any such Letter of Credit or of
the proceeds thereof; (vii) the misapplication by the beneficiary of any such Letter of Credit of
the proceeds of any drawing under such Letter of Credit; or (viii) any consequences arising from
causes beyond the control of such Issuing Lender, including any act or omission by a Governmental
Authority, and none of the above shall affect or impair, or prevent the vesting of, any of such
Issuing Lender’s rights or powers hereunder.

          In furtherance and extension and not in limitation of the specific provisions set forth in the
first paragraph of this subsection 4.5, any action taken or omitted by any Issuing Lender under or
in connection with the Letters of Credit issued by it or any documents and certificates delivered
thereunder, if taken or omitted in good faith, shall not put such Issuing Lender under any
resulting liability to Company.

          Notwithstanding anything to the contrary contained in this subsection 4.5, Company shall
retain any and all rights it may have against any Issuing Lender for any liability arising solely
out of the gross negligence or willful misconduct of such Issuing Lender, as determined by a final
judgment of a court of competent jurisdiction.

Party and shall promptly notify Administrative Agent and Collateral Agent of:

(a) any change in the location of any Loan Party’s chief executive office,

(b) any acquisition (whether by purchase, lease or otherwise) of any
property or assets which are intended to be used or kept outside of Alberta,
British Columbia, Saskatchewan and Ontario by Company or any

 (First Amended and Restated Credit Agreement)

 - 72 -

 

Subsidiary Guarantor or any relocation of existing assets outside said
jurisdictions, and

(c) any of Company or Subsidiary Guarantor acquiring (whether by purchase,
lease or otherwise, and including the purchase of previously leased
equipment from the lessor thereof) an interest in individual real
properties, or in vehicles or other equipment, security in respect of which
can be registered in a personal property registry by way of serial number,
and where any such asset has a cost or book value in excess of Cdn.$500,000,
in the case of real property interests, or in excess of Cdn.$1,250,000, in
the case of such vehicles or other equipment,

     and shall comply with the additional covenants set forth in the Collateral Documents with
respect to the foregoing.

          Company shall, at its expense, register, file or record the Collateral Documents (which

where such registration, filing or recording is necessary or of advantage to the creation,
perfection and preserving of the security applicable to any interests that are the subject of
clauses (c) and (d) above.

     5.3 Sharing Collateral Documents.

          Company and the Lenders agree and acknowledge that the Collateral Documents are being held by
Collateral Agent to secure the Obligations and the Secured Swap Obligations on a pari passu basis.
For purposes of the above sentence, pari passu basis means:

     (i) with respect to the Lenders (other than the Issuing Lender), proportional between
(a) the Obligations owed to Lenders having Revolving Loan Exposure, and (b) the aggregate of
the Obligations plus the Secured Swap Obligations;

     (ii) with respect to each Issuing Lender, proportional between (a) the Obligations owed
to it on account of Letter of Credit Usage, and (b) the aggregate of the Obligations plus
the Secured Swap Obligations; and

     (iii) with respect to the Swap Lenders, proportional between (a) the Secured Swap
Obligations and (b) the aggregate of the Obligations plus the Secured Swap Obligations.

          The Swap Lenders, as amongst themselves, will share their pro rata allocation of the
Collateral Documents, as determined in paragraph (iii) above, based on a pro rata allocation of the
aggregate outstanding Secured Swap Obligations (determined, if netting is legally available to a
Swap Lender, on a net basis) owing to each Swap Lender.

          If requested by any of Administrative Agent, Collateral Agent, the Requisite Lenders, an
Issuing Lender or any Swap Lender, then each of Collateral Agent, Administrative

(First Amended and Restated Credit Agreement)

 - 73 -

 

Agent and the Swap Lenders will enter into such further intercreditor agreements and
assurances as may be reasonably requested to further evidence the sharing provisions of this
subsection. The parties hereto agree, and such further agreements shall confirm, that Swap Lenders
shall be entitled to share in the proceeds of realization as aforesaid, but shall have no vote in
respect of amounts owed to them, and shall not have the right to initiate the enforcement of, or
participate in any decisions in respect of the enforcement of, any of the Loan Documents unless and
until there is no Revolving Loan Exposure, and this Agreement has been terminated.

     5.4 Form of Collateral Documents.

          If Collateral Agent, acting reasonably, determines at any time and from time to time that the
form and nature of the then existing Collateral Documents is deficient in any way or does not fully
provide Agents and the Lenders and the Swap Lenders with the security and priority to which each is
entitled hereunder, Company will forthwith execute and deliver or cause to be executed and
delivered to Administrative Agent and Collateral Agent, at Company’s expense, such amendments to
the Collateral Documents or provide such new security as Administrative Agent or Collateral Agent
may reasonably request.

          The forms of Collateral Documents shall have been or be prepared based upon the laws of
Alberta and other Applicable Laws in effect at the date hereof. Collateral Agent shall have the
right to require that:

     (i) any such Collateral Documents be amended to reflect any changes in such laws,
whether arising as a result of statutory amendments, court decisions or otherwise, in order
to confer upon Collateral Agent the rights and remedies intended to be created thereby, and

     (ii) Company and the Subsidiary Guarantors execute and deliver to Administrative Agent
and Collateral Agent such other and further debentures, mortgages, trust deeds, assignments
and security agreements as may be reasonably required to ensure Collateral Agent has and
holds First Priority Liens on and against all of the property and assets of Company and the
Subsidiary Guarantors for the benefit of the Agents, Lenders and the Swap Lenders.

     5.5 After-Acquired Property.

          All property acquired by or on behalf of Company or a Subsidiary Guarantor after the date of
execution of the Collateral Documents (hereinafter collectively referred to as “After-Acquired
Property”), will be subject to the charges and security interests of the Debentures, without any
further conveyance, mortgage, pledge, charge, assignment or other act on the part of such parties.
Without limiting the effect of the preceding sentence, Company will from time to time, at the
request of the Collateral Agent, acting reasonably, execute and deliver, or cause to be executed
and delivered, and in consultation with Collateral Agent will cause to be registered (which
requirement to register may be satisfied by the Collateral Agent), all at Company’s expense, such
instruments supplemental to the Collateral Documents, in form and substance satisfactory to
Collateral Agent, acting reasonably, as may be necessary or desirable to ensure

(First Amended and Restated Credit Agreement)

 - 74 -

 

that the Collateral Documents as amended and supplemented constitute in favour of Collateral
Agent for the benefit of the Agents, the Lenders and the Swap Lenders a valid First Priority Lien
over such After-Acquired Property as required hereunder.

     5.6 Continuing Collateral Documents.

          Each item or part of the Collateral Documents shall for all purposes be treated as a separate
and continuing collateral security and shall be deemed to have been given in addition to and not in
place of any other item or part of the Collateral Documents or any other security now held or
hereafter acquired by Administrative Agent, Collateral Agent or the Lenders. No item or part of the
Collateral Documents shall be merged or be deemed to have been merged in or by this Agreement or
any documents, instruments or acknowledgements delivered hereunder, or any simple contract debt or
any judgment, and any realization of or steps taken under or pursuant to any security, instrument
or agreement shall be independent of and not create a merger with any other right available to the
Lenders, the Collateral Agent or Administrative Agent under any security, instruments or agreements
held by it or at law or in equity.

     5.7 Dealing with Collateral Documents.

          Administrative Agent, with the consent of Requisite Lenders to the extent required by
subsection 12.6, may grant extensions of time or other indulgences, accept compositions, and
otherwise deal with Company and other parties as Administrative Agent may see fit, and may, subject
to Section 5.3, during the existence of an Event of Default, apply all amounts received from
Company or others or from securities (including the Collateral Documents or any part thereof) upon
such part of the liabilities of Company hereunder or under any of the Collateral Documents as
Administrative Agent may think best, without prejudice to or in any way limiting the liability of
Company and its Subsidiaries under this Agreement or under any of the Collateral Documents or any
other collateral security.

     5.8 Effectiveness.

          The Collateral Documents shall be effective, and the undertakings as to the Collateral
Documents herein or in any other Loan Document shall be continuing, whether any Loans or Letters of
Credit are then outstanding or any amounts thereby secured or any part thereof shall be owing
before or after, or at the same time as, the creation of such Collateral Documents or before or
after or upon the date of execution of any amendments to this Agreement.

     5.9 Release and Discharge of Collateral Documents.

          Except to the extent set forth in Section 11.6 and 12.14, 12.15, the Loan Parties shall not be
discharged from the Collateral Documents or any part thereof except by a written release and
discharge signed by Collateral Agent with the prior written consent of all Lenders and Swap
Lenders. If all of the Obligations and Secured Swap Obligations have been repaid, paid, satisfied
and discharged, as the case may be, in full and the credit facilities established hereby have been
fully cancelled, then the Collateral Documents shall be released and discharged

(First Amended and Restated Credit Agreement)

 - 75 -

 

by Collateral Agent, the Lenders and the Swap Lenders. Collateral Agent, at the cost and
expense of Company, shall from time to time do, execute and deliver, or cause to be done, executed
and delivered, all such agreements, instruments, certificates, financing statements, notices and
other documents and all acts, matters and things as may be reasonably requested by Company to give
effect to, establish, evidence or record the foregoing release and discharge.

     5.10 Transfer of Collateral Documents.

          If BNP PARIBAS (Canada), in its capacity as Collateral Agent, or any successor thereto, in its
capacity as Collateral Agent ceases to be Collateral Agent, such departing agent shall transfer and
assign all of the Collateral Documents to the replacement agent.

Section 7. COMPANY’S REPRESENTATIONS AND WARRANTIES

          In order to induce Lenders to enter into this Agreement and to make the Loans, to induce
Issuing Lenders to issue Letters of Credit and to induce Revolving Lenders to purchase
participations therein, Company represents and warrants to Administrative Agent, Collateral Agent
and each Lender:

     7.1 Organization, Powers, Qualification, Good Standing, Business and Subsidiaries.

     A. Organization and Powers. Each of Holdings and its Subsidiaries is duly organized, validly
existing and in good standing under the laws of its jurisdiction of organization as specified in
Schedule 7.1 annexed hereto (or in such other jurisdictions as are permitted hereby). Each
of Holdings and its Subsidiaries has all requisite corporate or partnership power and authority to
own and operate its properties, to carry on its business as now conducted and as proposed to be
conducted, to enter into the Loan Documents to which it is a party and to carry out the
transactions contemplated thereby.

     B. Qualification and Good Standing. Each of Holdings and its Subsidiaries is qualified to do
business and is in good standing in every jurisdiction in which the location of its assets or the
conduct of its business require it to be so qualified and in good standing, except in
jurisdictions where the failure to be so qualified or in good standing has not had and could not
reasonably be expected to result in a Material Adverse Effect.

     C. Conduct of Business. Holdings and its Subsidiaries are engaged only in the businesses
permitted to be engaged in pursuant to subsections 9.10, 10.13 and 10.14.

     D. Subsidiaries. All of the Subsidiaries of Company as of the Restatement Date and their
jurisdictions of organization are identified in Schedule 7.1 annexed hereto, as said

(First Amended and Restated Credit Agreement)

 - 82 -

 

Schedule 7.1 may be supplemented from time to time pursuant to the provisions of
subsection 8.1(xii). The Capital Stock of each of the Subsidiaries of Company identified in
Schedule 7.1 annexed hereto (as so supplemented), is duly authorized, validly issued, fully
paid and nonassessable (in each case to the extent such legal concept is applicable to such type of
Capital Stock) and none of such Capital Stock constitutes Margin Stock. Schedule 7.1
annexed hereto (as so supplemented) correctly sets forth the ownership interest of Company and each
of its Subsidiaries in each of the Subsidiaries of Company identified therein.

     7.2 Authorization of Borrowing, etc.

     A. Authorization of Borrowing. The execution, delivery and performance of the Loan Documents
have been duly authorized by all necessary action on the part of each Loan Party that is a party
thereto.

     B. No Conflict. The execution, delivery and performance by Loan Parties of the Loan Documents
and the Related Documents (except the Acquisition Agreement) to which they are parties and the
consummation of the transactions contemplated by the Loan Documents and the Related Documents
(except the Acquisition Agreement) do not and will not (i) violate any provision of any law or any
governmental rule or regulation applicable to Holdings or any of its Subsidiaries, the
Organizational Documents of Holdings or any of its Subsidiaries or any order, judgment or decree of
any court or other Governmental Authority binding on Holdings or any of its Subsidiaries, (ii)
conflict with, result in a breach of or constitute (with due notice or lapse of time or both) a
default under any material Contractual Obligation of Holdings or any of its Subsidiaries including,
without limitation, the existing Senior Note Indenture, (iii) result in or require the creation or
imposition of any Lien upon any of the properties or assets of Holdings or any of its Subsidiaries
(other than any Liens created under any of the Loan Documents in favor of Collateral Agent on
behalf of Lenders, Swap Lenders and Agents), or (iv) require any approval of stockholders or any
approval or consent of any Person under any material Contractual Obligation of Holdings or any of
its Subsidiaries, except for such approvals or consents which will be obtained on or before the
Restatement Date and disclosed in writing to Lenders.

     C. Governmental Consents. The execution, delivery and performance by Loan Parties of the Loan
Documents to which they are parties and the consummation of the transactions contemplated by the
Loan Documents do not and will not require any Governmental Authorization, except as have been
obtained, or are being obtained and listed in Schedule 7.2, or are registrations of the
Collateral Documents being made pursuant to Section 5.2.

     D. Binding Obligation. Each of the Loan Documents has been duly executed and delivered by
each Loan Party that is a party thereto and is the legally valid and binding obligation of such
Person, enforceable against such Person in accordance with its respective terms, except as may be
limited by bankruptcy, insolvency, reorganization, moratorium or similar laws relating to or
limiting creditors’ rights generally or by equitable principles relating to enforceability.

          Company has heretofore delivered to Administrative Agent, at Lenders’ request, the financial

financial statements as at the respective dates thereof and the results of operations and cash
flows (on a consolidated basis) of the entities described therein for each of the periods then
ended, subject, in the case of any such unaudited financial statements, to changes resulting from
audit, absence of footnotes and normal year-end adjustments. As of the Restatement Date, neither
Company nor any of its Subsidiaries has (and immediately following the funding of the initial Loans
will not have) any Contingent Obligation, contingent liability or liability for taxes, long-term
lease or unusual forward or long-term commitment that is not reflected in the foregoing financial

and Company does not have knowledge of any defaults by any third party currently existing
thereunder, in any case where any such defaults could reasonably be expected, individually or in
the aggregate, to have a Material Adverse Effect. Each such agreement constitutes the legally valid
and binding obligation of each applicable Loan Party, enforceable against such Loan Party in
accordance with its terms, except as enforcement may be limited by bankruptcy, insolvency,
reorganization, moratorium or similar laws relating to or limiting creditors’ rights generally or
by equitable principles.

force and effect and no defaults by any Loan Party currently exist thereunder, and Company does not
have knowledge of any defaults by any third party currently existing thereunder, in any case where

have the right to use all Intellectual Property used in the conduct of their business,
except where the failure to own or have such right to use in the aggregate could not
reasonably be expected to result in a Material Adverse Effect. No claim has been asserted and is
pending by any Person challenging or questioning the use of any such Intellectual Property or the
validity or effectiveness of any such Intellectual Property, nor does Company know of any valid
basis for any such claim, except for such claims that in the aggregate could not reasonably
be expected to result in a Material Adverse Effect. The use of such Intellectual Property by
Company and its Subsidiaries does not infringe on the rights of any Person, except for such
claims and infringements that, in the aggregate, could not reasonably be expected to result in a
Material Adverse Effect. All applicable registrations of and applications for Intellectual
Property, and all unregistered Intellectual Property, that are owned or licensed by Company or any

this Agreement and the other Loan Documents, as applicable. Except for subsections 11.1B, 11.5 and
11.6, the provisions of this Section 11 are solely for the benefit of Administrative Agent,
Collateral Agent and Lenders and no Loan Party shall have rights as a third party beneficiary of
any of the provisions thereof. In performing its functions and duties under this Agreement,

deemed to have assumed any obligation towards or relationship of agency or trust with or for
Company or any other Loan Party.

     B. Appointment of Collateral Agent. BNP PARIBAS (Canada) is hereby appointed Collateral Agent
hereunder and under the other Loan Documents. Each Lender hereby authorizes Collateral Agent to
act as its agent in accordance with the terms of this Agreement and the other Loan Documents.
Collateral Agent agrees to act upon the express conditions contained in this Agreement and the
other Loan Documents, as applicable. Except for subsections 11.1B, 11.5 and 11.6, the provisions
of this Section 11 are solely for the benefit of Administrative Agent, Collateral Agent and Lenders
and no Loan Party shall have rights as a third party beneficiary of any of the provisions thereof.
In performing its functions and duties under this Agreement, Collateral Agent shall act solely as
an agent of Lenders and does not assume and shall not be deemed to have assumed any obligation
towards or relationship of agency or trust with or for Company or any other Loan Party.

     C. Appointment of Supplemental Collateral Agents. It is the purpose of this Agreement and the
other Loan Documents that there shall be no violation of any law of any jurisdiction denying or
restricting the right of banking corporations or associations to transact business as agent or
trustee in such jurisdiction. It is recognized that in case of litigation under this Agreement or
any of the other Loan Documents, and in particular in case of the enforcement of any of the Loan
Documents, or in case Collateral Agent deems that by reason of any present or future law of any
jurisdiction it may not exercise any of the rights, powers or remedies granted herein or in any of
the other Loan Documents or take any other action which may be desirable or necessary in connection
therewith, it may be necessary that Collateral Agent appoint an additional individual or
institution as a separate trustee, co-trustee, collateral agent or collateral co-agent (any such
additional individual or institution being referred to herein individually as a “Supplemental
Collateral Agent” and collectively as “Supplemental Collateral Agents”).

          In the event that Collateral Agent appoints a Supplemental Collateral Agent with respect to
any Collateral, (i) each and every right, power, privilege or duty, and each obligation, expressed
or intended by this Agreement or any of the other Loan Documents to be exercised by or vested in or
conveyed to Collateral Agent, or to which Collateral Agent is subject, with respect to such
Collateral shall be exercisable by and vest in such Supplemental Collateral Agent to the extent,
and only to the extent, necessary to enable such Supplemental Collateral Agent to exercise such
rights, powers and privileges with respect to such Collateral as if such

(First Amended and Restated Credit Agreement)

- 120 -

 

Supplemental Collateral Agent were the Collateral Agent, and to perform such duties with
respect to such Collateral, and every covenant and obligation contained in the Loan Documents and
necessary to the exercise or performance thereof by and against such Supplemental Collateral Agent
shall run to and be enforceable by and against either Collateral Agent or such Supplemental

such Supplemental Collateral Agent, as the context may require.

          Should any instrument in writing from Company or any other Loan Party be required by any
Supplemental Collateral Agent so appointed by Collateral Agent for more fully and certainly vesting
in and confirming to him or it such rights, powers, privileges and duties, Company shall, or shall
cause such Loan Party to, execute, acknowledge and deliver any and all such instruments promptly
upon request by Collateral Agent. In case any Supplemental Collateral Agent, or a successor
thereto, shall die, become incapable of acting, resign or be removed, all the rights, powers,
privileges and duties of such Supplemental Collateral Agent, to the extent permitted by Applicable
Law, shall vest in and be exercised by Collateral Agent until the appointment of a new Supplemental
Collateral Agent.

     D. Control. Each Lender and Collateral Agent hereby appoint each other Lender as agent for
the purpose of perfecting Administrative Agent’s security interest in assets that, in accordance
with any governing legislation, can be perfected by possession or control.

     11.2 Powers and Duties; General Immunity.

     A. Powers; Duties Specified. Each Lender irrevocably authorizes Administrative Agent to take
such action on such Lender’s behalf and to exercise such powers, rights and remedies hereunder and
under the other Loan Documents as are specifically delegated or granted to Administrative Agent by
the terms hereof and thereof, together with such powers, rights and remedies as are reasonably
incidental thereto. Administrative Agent shall have only those duties and responsibilities that
are expressly specified in this Agreement and the other Loan Documents together with such powers,
rights and remedies as are reasonably incidental thereto. Administrative Agent may exercise such
powers, rights and remedies and perform such duties by or through its agents or employees.
Administrative Agent shall not have, by reason of this Agreement or any of the other Loan
Documents, a fiduciary relationship in respect of any Lender or Company; and nothing in this
Agreement or any of the other Loan Documents, expressed or implied, is intended to or shall be so
construed as to impose upon Administrative Agent any obligations in respect of this Agreement or
any of the other Loan Documents except as expressly set forth herein or therein.

     Each Lender irrevocably authorizes Collateral Agent to take such action on such Lender’s
behalf and to exercise such powers, rights and remedies hereunder and under the other Loan
Documents as are specifically delegated or granted to Collateral Agent by the terms hereof and
thereof, together with such powers, rights and remedies as are reasonably incidental thereto.
Collateral Agent shall have only those duties and responsibilities that are expressly specified in
this Agreement and the other Loan Documents together with such powers, rights and remedies as

(First Amended and Restated Credit Agreement)

- 121 -

 

are reasonably incidental thereto. Collateral Agent may exercise such powers, rights and remedies
and perform such duties by or through its agents or employees. Collateral Agent shall not have, by
reason of this Agreement or any of the other Loan Documents, a fiduciary relationship in respect of
any Lender or Company; and nothing in this Agreement or any of the other Loan Documents, expressed
or implied, is intended to or shall be so construed as to impose upon Collateral Agent any
obligations in respect of this Agreement or any of the other Loan Documents except as expressly set
forth herein or therein.

     B. No Responsibility for Certain Matters. No Agent shall be responsible to any Lender for the
execution, effectiveness, genuineness, validity, enforceability, collectibility or sufficiency of
this Agreement or any other Loan Document or for any representations, warranties, recitals or
statements made herein or therein or made in any written or oral statements or in any financial or
other statements, instruments, reports or certificates or any other documents furnished or made by
such Agent to Lenders or by or on behalf of Company to such Agent or any Lender in connection with
the Loan Documents and the transactions contemplated thereby or for the financial condition or
business affairs of Company or any other Person liable for the payment of any Obligations, nor
shall such Agent be required to ascertain or inquire as to the performance or observance of any of
the terms, conditions, provisions, covenants or agreements contained in any of the Loan Documents
or as to the use of the proceeds of the Loans or the use of the Letters of Credit or as to the
existence or possible existence of any Event of Default or Potential Event of Default. Anything
contained in this Agreement to the contrary notwithstanding, Administrative Agent shall not have
any liability arising from confirmations of the amount of outstanding Loans or the Letter of Credit
Usage or the component amounts thereof.

     C. Exculpatory Provisions. No Agent or any of its officers, directors, employees or agents
shall be liable to Lenders for any action taken or omitted by such Agent under or in connection
with any of the Loan Documents except to the extent caused by such Agent’s gross negligence or
willful misconduct. An Agent shall be entitled to refrain from any act or the taking of any action
(including the failure to take an action) in connection with this Agreement or any of the other
Loan Documents or from the exercise of any power, discretion or authority vested in it hereunder or
thereunder unless and until such Agent shall have received instructions in respect thereof from
Requisite Lenders (or such other Lenders as may be required to give such instructions under
subsection 12.6) and, upon receipt of such instructions from Requisite Lenders (or such other
Lenders, as the case may be), such Agent shall be entitled to act or (where so instructed) refrain
from acting, or to exercise such power, discretion or authority, in accordance with such
instructions. Without prejudice to the generality of the foregoing, (i) each Agent shall be
entitled to rely, and shall be fully protected in relying, upon any communication, instrument or
document believed by it to be genuine and correct and to have been signed or sent by the proper
person or persons, and shall be entitled to rely and shall be protected in relying on opinions and
judgments of attorneys (who may be attorneys for Company and its Subsidiaries), accountants,
experts and other professional advisors selected by it; and (ii) no Lender shall have any right of
action whatsoever against an Agent as a result of such Agent acting or (where so instructed)
refraining from acting under this Agreement or any of the other Loan Documents in

(First Amended and Restated Credit Agreement)

- 122 -

 

accordance with the instructions of Requisite Lenders (or such other Lenders as may be
required to give such instructions under subsection 12.6).

     D. Agents Entitled to Act as Lender. The agency hereby created shall in no way impair or
affect any of the rights and powers of, or impose any duties or obligations upon, an Agent in its
individual capacity as a Lender hereunder. With respect to its participation in the Loans and the
Letters of Credit, an Agent shall have the same rights and powers hereunder as any other Lender and
may exercise the same as though it were not performing the duties and functions delegated to it
hereunder, and the term “Lender” or “Lenders” or any similar term shall, unless the context clearly
otherwise indicates, include each Agent in its individual capacity. An Agent and its Affiliates
may accept deposits from, lend money to, acquire equity interests in and generally engage in any
kind of commercial banking, investment banking, trust, financial advisory or other business with
Company or any of its Affiliates as if it were not performing the duties specified herein, and may
accept fees and other consideration from Company for services in connection with this Agreement and
otherwise without having to account for the same to Lenders.

     11.3 Independent Investigation by Lenders; No Responsibility For Appraisal of
Creditworthiness.

          Each Lender agrees that it has made its own independent investigation of the financial
condition and affairs of Company and its Subsidiaries in connection with the making of the Loans
and the issuance of Letters of Credit hereunder and that it has made and shall continue to make its
own appraisal of the creditworthiness of Company and its Subsidiaries. No Agent shall have any duty
or responsibility, either initially or on a continuing basis, to make any such investigation or any
such appraisal on behalf of Lenders or to provide any Lender with any credit or other information
with respect thereto, whether coming into its possession before the making of the Loans or issuance
of any Letter of Credit or at any time or times thereafter, and no Agent shall have any
responsibility with respect to the accuracy of or the completeness of any information provided to
Lenders.

     11.4 Right to Indemnity.

          Each Lender, in proportion to its Pro Rata Share, severally agrees to indemnify each Agent and
its officers, directors, employees, agents, attorneys, professional advisors and Affiliates to the
extent that any such Person shall not have been reimbursed by Company, for and against any and all
liabilities, obligations, losses, damages, penalties, actions, judgments, suits, costs, expenses
(including counsel fees and disbursements on a solicitor and his own client basis, and fees and
disbursements of any financial advisor engaged by Agents) or disbursements of any kind or nature
whatsoever which may be imposed on, incurred by or asserted against an Agent or and other such
Persons in exercising the powers, rights and remedies of an Agent or performing duties of an Agent
hereunder or under the other Loan Documents or otherwise in its capacity as Agent in any way
relating to or arising out of this Agreement or the other Loan Documents, provided that no
Lender shall be liable for any portion of such liabilities, obligations, losses, damages,
penalties, actions, judgments, suits, costs, expenses or disbursements of an Agent resulting solely
from such Agent’s gross negligence or willful misconduct as determined by a

(First Amended and Restated Credit Agreement)

- 123 -

 

final judgment of a court of competent jurisdiction. If any indemnity furnished to an Agent
or any other such Person for any purpose shall, in the opinion of such Agent, be insufficient or
become impaired, such Agent may call for additional indemnity and cease, or not commence, to do the
acts indemnified against until such additional indemnity is furnished.

     11.5 Successor Agents and Swing Line Lender.

     A. Successor Agents. Any Administrative Agent may resign at any time by giving 30 days’ prior
written notice thereof to Collateral Agent, Lenders and Company. Upon any such notice of

In such event Company shall prepay any outstanding Swing Line Loans made by the retiring or removed

from its duties and obligations under this Agreement upon its resignation becoming effective in
accordance with its notice of resignation. After any retiring Fronting Bank’s resignation
hereunder as Fronting Bank, the provisions of this Agreement shall inure to its benefit as to any
actions taken or omitted to be taken by it while it was a Fronting Bank under this Agreement.

     11.6 Collateral Documents and Guarantees.

     A. Each Lender hereby further authorizes Administrative Agent, on behalf of and for the
benefit of Lenders, to be the agent for and representative of Lenders under any Loan Document
(other than this Agreement and the Collateral Documents) and each Lender agrees to be bound by the
terms of each such Loan Document, provided that Administrative Agent shall not enter into
or consent to any material amendment, modification, termination or waiver of any provision
contained in any such Loan Document, except in compliance with subsection 12.6, and
provided further that, without further written consent or authorization from
Lenders, Administrative Agent may execute any documents or instruments necessary to release any
Subsidiary Guarantor from the Subsidiary Guarantee if all of the Capital Stock of such Subsidiary
Guarantor is sold to any Person (other than an Affiliate of Company) pursuant to a sale or other
disposition permitted hereunder or to which Requisite Lenders have otherwise consented so long as,

requirements of subsections 12.14 and 12.15 are satisfied. In addition, each Lender (and by
accepting the benefits thereof, each Swap Lender) hereby further authorizes Administrative Agent to
execute the St. Paul Priority Agreement as agent for and representative of the Lenders, and each
Lender (and by accepting the benefits thereof, each Swap Lender) agrees to be bound thereby.
Anything contained in any of the Loan Documents to the contrary notwithstanding, Company,
Administrative Agent and each Lender hereby agree that no Lender shall have any right individually
to enforce any Guarantee, it being understood and agreed that all powers, rights and remedies under
the Guarantees may be exercised solely by Administrative Agent for the benefit of Lenders in
accordance with the terms thereof.

     B. Each Lender (and by accepting the benefits thereof, each Swap Lender) hereby further

a sale or other disposition of assets permitted by this Agreement or to which
Requisite Lenders have otherwise consented, or

     (b) subordinate the Liens of Collateral Agent, on behalf of Lenders, Swap
Lenders and Agents, to any Liens permitted by subsections 9.2A(i), (ii) and (iv);

so long as, in the case of a sale of such item of Collateral referred to in subclause (a), the
requirements of subsections 12.14 and 12.15 are satisfied. Anything contained in any of the
Collateral Documents to the contrary notwithstanding, Company, Collateral Agent and each Lender
hereby agree that:

     (1) no Lender shall have any right individually to realize upon any of
the Collateral under any Collateral Document, it being understood and agreed
that all powers, rights and remedies under the Collateral Documents may be
exercised solely by Collateral Agent for the benefit of Lenders in
accordance with the terms thereof, and

     (2) in the event of a foreclosure by Collateral Agent on any of the
Collateral pursuant to a public or private sale, Collateral Agent,
Administrative Agent or any Lender may be the purchaser of any or all of
such Collateral at any such sale and Administrative Agent, as agent for and

respective individual capacities unless Requisite Lenders shall otherwise
agree in writing) shall be entitled, for the purpose of bidding and making
settlement or payment of the purchase price for all or any portion of the
Collateral sold at any such public sale, to use and apply any of the
Obligations as a credit on account of the purchase price for any collateral
payable by Collateral Agent at such sale.

agent or syndication agent, such Lender shall not have any right, power, obligation, liability,
responsibility or duty under this Agreement other than those applicable to all Lenders as such.
Without limiting the foregoing, none of such Lenders shall have or be deemed to have a fiduciary
relationship with any Lender.

     11.8 Administrative Agent May File Proofs of Claim.

bankruptcy, reorganization, arrangement, adjustment, composition or other
judicial proceeding relative to

Holdings, Company or any of the Subsidiaries of Holdings or Company, Administrative Agent
(irrespective of whether the principal of any Loan shall then be due and payable as herein

unpaid in respect of the Loans or Letters of Credit and any other Obligations that are owing

adjustment or composition affecting the Obligations or the rights of any Lenders or to authorize
Administrative Agent to vote in respect of the claim of any Lender in any such proceeding.

Line Lender may not be sold, assigned or transferred as described below to any Person other than a
successor Administrative Agent and Swing Line Lender to the extent contemplated by subsection 11.5.
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 and, to
the extent expressly contemplated hereby, the Affiliates of each Agent and Lenders) any legal or
equitable right, remedy or claim under or by reason of this Agreement.

     B. Assignments.

Eligible Assignees all or any portion of its rights and obligations under this Agreement,
provided that:

     (a) except (1) in the case of an assignment of the entire remaining amount of
the assigning Lender’s rights and obligations under this Agreement or (2) in the
case of an assignment to a Lender or an Affiliate of a Lender or Agent or an
Approved Fund of a Lender, the aggregate amount of the Revolving Loan Exposure of
the assigning Lender and the assignee subject to each such assignment shall not be
less than Cdn. $1,000,000 in the case of any assignment of a Revolving Loan or
Revolving Loan Commitment, unless each of Administrative Agent and, so long as no
Event of Default has occurred and is continuing, Company otherwise consents (each
such consent not to be unreasonably withheld or delayed),

     (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 with
respect to the Loan or the Revolving Loan Commitment assigned,

     (c) the assignor and the assignee under each assignment shall execute and
deliver to Administrative Agent an Assignment Agreement, together with a processing
and recordation fee of $3,500 (unless the assignee is an Affiliate or an Approved
Fund of the assignor, in which case no fee shall be required), and the Eligible
Assignee, if it shall not be a Lender, shall deliver to Administrative Agent
information reasonably requested by Administrative Agent), and

(First Amended and Restated Credit Agreement)

- 128 -

 

     (d) except in the case of an assignment to another Lender, an Affiliate of a
Lender or Agent or an Approved Fund of a Lender, Agents, if no Event of Default has
occurred and is continuing, Company, shall have consented thereto (each of which
consents shall not be unreasonably withheld and in the case of Collateral Agent such
consent may only be withheld if in Collateral Agent’s reasonable judgment such
assignment would likely result in additional liability, cost or administrative
burden for the Collateral Agent), and shall evidence such consent in writing on
request by any party to the Assignment Agreement. Collateral Agent’s consent to any
assignment shall be deemed given 5 Business Days after written request therefor by
Administrative Agent or Company if, by such time Collateral Agent has not consented
(or denied consent).

Upon such execution, delivery and consent, from and after the effective date specified in
such Assignment Agreement, (y) the assignee thereunder shall be a party hereto and, to the
extent that rights and obligations hereunder have been assigned to it pursuant to such
Assignment Agreement, shall have the rights and obligations of a Lender hereunder and (z)
the assigning Lender thereunder shall, to the extent that rights and obligations hereunder
have been assigned by it pursuant to such Assignment Agreement, relinquish its rights (other
than any rights which survive the termination of this Agreement under subsection 12.9B) and
be released from its obligations under this Agreement (and, in the case of an Assignment
Agreement covering all or the remaining portion of an assigning Lender’s rights and
obligations under this Agreement, such Lender shall cease to be a party hereto,
provided that, anything contained in any of the Loan Documents to the contrary
notwithstanding, if such Lender is an Issuing Lender such Lender shall continue to have all
rights and obligations of an Issuing Lender until the cancellation or expiration of any
Letters of Credit issued by it and the reimbursement of any amounts drawn thereunder). Other
than as provided in subsection 2.1A(ii) and subsection 12.5, any assignment or transfer by a
Lender of rights or obligations under this Agreement that does not comply with this
subsection 12.1B 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 subsection 12.1C.

     (ii) Acceptance by Administrative Agent; Recordation in Register. Upon its
receipt of an Assignment Agreement executed by an assigning Lender and an assignee
representing that it is an Eligible Assignee, together with the processing and recordation
fee referred to in subsection 12.1B(i), Administrative Agent shall, if Administrative Agent
and Company have consented to the assignment evidenced thereby (in each case to the extent
such consent is required pursuant to subsection 12.1B(i)), (a) accept such Assignment
Agreement by executing a counterpart thereof as provided therein (which acceptance shall
evidence any required consent of Administrative Agent to such assignment), (b) record the
information contained therein in the Register, and (c) give prompt notice thereof to
Company. Administrative Agent shall maintain a copy of each Assignment Agreement delivered
to and accepted by it as provided in this subsection 12.1B(ii).

(First Amended and Restated Credit Agreement)

- 129 -

 

     (iii) Deemed Consent by Company. If the consent of Company to an assignment or
to an Eligible Assignee is required hereunder (including a consent to an assignment which
does not meet the minimum assignment thresholds specified in subsection 12.1B(i), but
excluding any consent of Company required for the sale of a participation set forth in
subsection 12.1C), Company shall be deemed to have given its consent five Business Days
after the date notice thereof has been delivered by the assigning Lender (through
Administrative Agent) unless such consent is expressly refused by Company on or prior to
such fifth Business Day.

     C. Participations. Any Lender may, without the consent of, or notice to, Company or
Administrative Agent, sell participations to one or more Persons (other than a natural Person or
Company or any of its Affiliates) in all or a portion of such Lender’s rights and/or obligations
under this Agreement, provided that (i) such Lender’s obligations under this Agreement
shall remain unchanged, (ii) such Lender shall remain solely responsible to the other parties
hereto for the performance of such obligations and (iii) Company, Administrative Agent and 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 directly affecting
(a) the extension of the regularly scheduled maturity of any portion of the principal amount of or
interest on any Loan allocated to such participation (other than interest imposed by subsection
2.2D for a period not to exceed 60 days) or (b) a reduction of the principal amount of or the rate
of interest payable on any Loan allocated to such participation (other than interest imposed by
subsection 2.2D for a period not to exceed 60 days). Subject to the further provisions of this
subsection 12.1C, Company agrees that each Participant shall be entitled to the benefits of
subsection 2.6 to the same extent as if it were a Lender and had acquired its interest by
assignment pursuant to subsection 12.1B. To the extent permitted by Applicable Law, each
Participant also shall be entitled to the benefits of subsection 12.4 as though it were a Lender,
provided such Participant agrees to be subject to subsection 12.5 and 12.20 as though it
were a Lender. A Participant shall not be entitled to receive any greater payment under subsection
2.6 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 Company’s prior written consent.

          Where payments to a Participant are subject to withholding tax pursuant to Part XIII of the
Income Tax Act, a Participant shall not be entitled to the benefits of subsection 2.6 unless
Company is notified of the participation sold to such Participant and Company agrees to comply with
subsection 2.6 as though such Participant were a Lender.

     D. Pledges and Assignments. Any Lender may at any time pledge or assign a security interest
in all or any portion of its Loans, and the other Obligations owed to such Lender, to any banking
or finance Governmental Authority to secure obligations of such Lender, including any pledge or
assignment to secure obligations to any Federal Reserve Bank, provided that (i) no Lender
shall be relieved of any of its obligations hereunder as a result of any such

(First Amended and Restated Credit Agreement)

- 130 -

 

assignment or pledge and (ii) in no event shall any assignee or pledgee be considered to be a
“Lender” or be entitled to require the assigning Lender to take or omit to take any action
hereunder.

     E. Information. Each Lender may furnish any information concerning Company and its
Subsidiaries in the possession of that Lender from time to time to assignees and participants
(including prospective assignees and participants), subject to subsection 12.20.

     F. Agreements of Lenders. Each Lender listed on the signature pages hereof hereby agrees, and
each Lender that becomes a party hereto pursuant to an Assignment Agreement shall be deemed to
agree, (i) that it is an Eligible Assignee described in clause (ii) of the definition thereof; (ii)
that it has experience and expertise in the making of or purchasing loans such as the Loans; and
(iii) that it will make or purchase Loans for its own account in the ordinary course of its
business and without a view to distribution of such Loans within the meaning of the Securities Act
or the Exchange Act or other securities laws (it being understood that, subject to the provisions
of this subsection 12.1, the disposition of such Loans or any interests therein shall at all times
remain within its exclusive control).

     12.2 Expenses.

    Whether or not the transactions contemplated hereby shall be consummated, Company agrees to
pay promptly:

       (i) all reasonable costs and expenses of the Agents incurred in connection with the
negotiation, preparation and execution of the Loan Documents and any consents, amendments,
waivers or other modifications thereto;

       (ii) all costs and expenses of furnishing all opinions by counsel for Company
(including any opinions requested by Agents or Lenders as to any legal matters arising
hereunder) and of Company’s performance of and compliance with all agreements and conditions
on its part to be performed or complied with under this Agreement and the other Loan
Documents including with respect to confirming compliance with environmental, insurance and
solvency requirements;

       (iii) all reasonable fees, expenses and disbursements of counsel to Administrative
Agent on a solicitor and his own client basis (including allocated costs of internal
counsel) in connection with the negotiation, preparation, execution and administration of
the Loan Documents and any consents, amendments, waivers or other modifications thereto and
any other documents or matters requested by Company;

       (iv) all costs and expenses of creating and perfecting Liens in favor of Collateral
Agent on behalf of Lenders, Swap Lenders and Agents pursuant to any Collateral Document,
including filing and recording fees, expenses and taxes, stamp or documentary taxes, search
fees and reasonable fees, expenses and disbursements of counsel to Administrative Agent and
Collateral Agent and of counsel providing any

(First Amended and Restated Credit Agreement)

- 131 -

 

opinions that Administrative Agent, Collateral Agent or Requisite Lenders may request
in respect of the Collateral Documents or the Liens created pursuant thereto;

     (v) all costs and expenses (including the reasonable fees, expenses and disbursements
of any auditors, accountants or appraisers and any environmental, engineering or other
consultants, advisors and agents employed or retained by Administrative Agent, Collateral
Agent or its counsel) of obtaining and reviewing any appraisals or any environmental audits
or reports provided for under this Agreement, provided that Administrative Agent and
Collateral Agent shall advise Company of Lenders’ intent to obtain such information,
although failure to do so will not affect Company’s obligations under this subsection 12.2;

     (vi) all costs and expenses incurred by Collateral Agent in connection with the custody
or preservation of any of the Collateral;

     (vii) all other costs and expenses incurred by Agents in connection with the

     (viii) all costs and expenses, including reasonable legal fees on a solicitor and his
own client basis (including allocated costs of internal counsel) and fees, costs and
expenses of accountants, advisors and consultants, incurred by Administrative Agent and
Collateral Agent and its counsel relating to efforts to (a) evaluate or assess any Loan
Party, its business or financial condition and (b) protect, evaluate, assess or dispose of
any of the Collateral; and

     (ix) all costs and expenses, including reasonable attorneys’ fees (including allocated
costs of internal counsel), fees, costs and expenses of accountants, advisors and
consultants and costs of settlement, incurred by Administrative Agent, Collateral Agent and
Lenders in enforcing any Obligations of or in collecting any payments due from any Loan
Party hereunder or under the other Loan Documents (including in connection with the sale of,
collection from, or other realization upon any of the Collateral or the enforcement of the
Loan Documents) or in connection with any refinancing or restructuring of the credit
arrangements provided under this Agreement in the nature of a “work-out” or pursuant to any
insolvency or bankruptcy proceedings.

     12.3 Indemnity.

             In addition to the payment of expenses pursuant to subsection 12.2, whether or not the
transactions contemplated hereby shall be consummated, Company agrees to defend, indemnify, pay and
hold harmless Agents and Lenders (including Issuing Lenders), and the officers, directors,
employees, agents and Affiliates of Agents and Lenders (collectively called the “Indemnitees”),
from and against any and all Indemnified Liabilities (as hereinafter defined), provided
that (i) an Indemnitee shall always be entitled to select its own counsel, and (ii) Company shall
not have any obligation to any Indemnitee hereunder with respect to any Indemnified Liabilities to
the extent such Indemnified Liabilities arise solely from the gross

(First Amended and Restated Credit Agreement)

- 132 -

 

negligence or willful misconduct of that Indemnitee as determined by a final judgment of a
court of competent jurisdiction.

          As used herein, “Indemnified Liabilities” means, collectively, any and all liabilities,
obligations, losses, damages (including natural resource damages), penalties, actions, judgments,
suits, claims (including Environmental Claims), costs (including the costs of any investigation,
study, sampling, testing, abatement, cleanup, removal, remediation or other response action
necessary to remove, remediate, clean up or abate any Hazardous Materials or Hazardous Materials
Activity), expenses and disbursements of any kind or nature whatsoever (including the reasonable
fees and disbursements of counsel for Indemnitees in connection with any investigative,
administrative or judicial proceeding commenced or threatened by any Person, whether or not any
such Indemnitee shall be designated as a party or a potential party thereto, and any fees or
expenses incurred by Indemnitees in enforcing this indemnity), whether direct, indirect or
consequential and whether based on any federal, state or foreign laws, statutes, rules or
regulations (including securities and commercial laws, statutes, rules or regulations and
Environmental Laws), on common law or equitable cause or on contract or otherwise, that may be
imposed on, incurred by, or asserted against any such Indemnitee, in any manner relating to or
arising out of:

     (i) this Agreement, the other Loan Documents or the Related Documents or the
transactions contemplated hereby or thereby (including Lenders’ agreement to make the Loans
hereunder or the use or intended use of the proceeds thereof or the issuance of Letters of
Credit hereunder or the use or intended use of any thereof, the failure of an Issuing Lender
to honor a drawing under a Letter of Credit as a result of any act or omission, whether
rightful or wrongful, of any present or future de jure or de facto Governmental Authority or
any enforcement of any of the Loan Documents (including any sale of, collection from, or
other realization upon any of the Collateral or the enforcement of the Guarantees)), and
further including:

     (a) any cost or expense incurred by reason of the liquidation or re-deployment
in whole or in part of deposits or other funds required by any Lender to fund any
Bankers’ Acceptance or to fund or maintain any Loan as a result of Company’s failure
to complete a borrowing or to make any payment, repayment or prepayment on the date
required hereunder or specified by it in any notice given hereunder;

     (b) subject to permitted or deemed Rollovers and Conversions, Company’s failure
to provide for the payment to Administrative Agent for the account of the Lenders of
the full principal amount of each Bankers’ Acceptance on its maturity date;

     (c) Company’s failure to pay any other amount, including any interest or fee,
due hereunder on its due date after the expiration of any applicable grace or notice
periods (subject, however, to the interest obligations of Company hereunder for
overdue amounts);

(First Amended and Restated Credit Agreement)

- 133 -

 

     (d) the prepayment of any outstanding Bankers’ Acceptance otherwise than on the
last day of its BA Interest Period;

     (e) Company’s failure to give any notice required to be given by it to
Administrative Agent or the Lenders hereunder;

     (f) the failure of Company to make any other payment due hereunder;

     (g) any inaccuracy or incompleteness of Company’s representations and
warranties contained herein;

     (h) any failure of Company to observe or fulfill its covenants contained
herein;

     (i) any failure of Company to observe or fulfill any other Obligation not
specifically referred to above; or

     (j) the occurrence of any Default or Event of Default in respect of Company; or

     (ii) any Environmental Claim or any Hazardous Materials Activity relating to or arising
from, directly or indirectly, any past or present activity, operation, land ownership, or
practice of Company or any of its Subsidiaries.

          To the extent that the undertakings to defend, indemnify, pay and hold harmless set forth in
this subsection 12.3 may be unenforceable in whole or in part because they are violative of any law
or public policy, Company shall contribute the maximum portion that it is permitted to pay and
satisfy under Applicable Law to the payment and satisfaction of all Indemnified Liabilities
incurred by Indemnitees or any of them.

     12.4 Set-Off; Security Interest in Deposit Accounts.

          In addition to any rights now or hereafter granted under Applicable Law and not by way of
limitation of any such rights, during the existence of any Event of Default (and with the approval
of the Requisite Lenders prior to any Loans becoming or being declared to be due under Section 10),
each Lender is hereby authorized by Company at any time or from time to time, without notice to
Company or to any other Person, any such notice being hereby expressly waived, to set off and to
appropriate and to apply any and all deposits (general or special, time or demand, provisional or
final, including Indebtedness evidenced by certificates of deposit, whether matured or unmatured,
but not including trust accounts) and any other Indebtedness at any time held or owing by that
Lender or any Affiliate of that Lender to or for the credit or the account of Company and each
other Loan Party against and on account of the Obligations of Company or any other Loan Party to
that Lender (or any Affiliate of that Lender) or to any other Lender (or any Affiliate of any other
Lender) under this Agreement, the Letters of Credit and participations therein and the other Loan
Documents, including all claims of any nature or description arising out of or connected with this
Agreement, the Letters of Credit and

(First Amended and Restated Credit Agreement)

- 134 -

 

participations therein or any other Loan Document, irrespective of whether or not (i) that
Lender shall have made any demand hereunder or (ii) the principal of or the interest on the Loans
or any amounts in respect of the Letters of Credit or any other amounts due hereunder shall have
become due and payable pursuant to Section 10 and although said obligations and liabilities, or any
of them, may be contingent or unmatured. Company hereby further grants to Collateral Agent and
each Lender a security interest in all deposits and accounts maintained with Administrative Agent,
Collateral Agent or such Lender as security for the Obligations.

     12.5 Ratable Sharing.

          Lenders hereby agree among themselves that if any of them shall, whether by voluntary payment
(other than a voluntary prepayment of Loans made and applied in accordance with the terms of this
Agreement), by realization upon security, through the exercise of any right of set-off or banker’s
lien, by counterclaim or cross action or by the enforcement of any right under the Loan Documents
or otherwise, or as adequate protection of a deposit treated as cash collateral under a Bankruptcy
Law, receive payment or reduction of a proportion of the aggregate amount of principal, interest,
amounts payable in respect of Letters of Credit, fees and other amounts then due and owing to that
Lender hereunder or under the other Loan Documents (collectively, the “Aggregate Amounts Due” to
such Lender) that is greater than the proportion received by any other Lender in respect of the
Aggregate Amounts Due to such other Lender, then the Lender receiving such proportionately greater
payment shall (i) notify Administrative Agent and each other Lender of the receipt of such payment
and (ii) apply a portion of such payment to purchase assignments (which it shall be deemed to have
purchased from each seller of an assignment simultaneously upon the receipt by such seller of its
portion of such payment) of the Aggregate Amounts Due to the other Lenders so that all such
recoveries of Aggregate Amounts Due shall be shared by all Lenders in proportion to the Aggregate
Amounts Due to them, provided that if all or part of such proportionately greater payment
received by such purchasing Lender is thereafter recovered from such Lender upon the bankruptcy,
receivership or reorganization of a Loan Party or otherwise, those purchases shall be rescinded and
the purchase prices paid for such assignments shall be returned to such purchasing Lender ratably
to the extent of such recovery, but without interest. Company expressly consents to the foregoing
arrangement and agrees that any purchaser of an assignment so purchased may exercise any and all
rights of a Lender as to such assignment as fully as if that Lender had complied with the
provisions of subsection 12.1B with respect to such assignment. In order to further evidence such
assignment (and without prejudice to the effectiveness of the assignment provisions set forth
above), each purchasing Lender and each selling Lender agree to enter into an assignment agreement
at the request of a selling Lender or a purchasing Lender, as the case may be, in form and
substance reasonably satisfactory to each such Lender.

     12.6 Amendments and Waivers.

          No amendment, modification, termination or waiver of any provision of this Agreement, and no
consent to any departure by Company therefrom, shall in any event be effective without the written
concurrence of Requisite Lenders, provided that no such amendment, modification,
termination, waiver or consent shall:

(First Amended and Restated Credit Agreement)

- 135 -

 

     (i) without the additional consent of each Lender with Obligations directly affected:

(a) reduce the principal amount payable on account of any Loan,

(b) increase the maximum aggregate amount of Letters of Credit available,

(c) postpone any installment date or the final maturity date of any Loan,

(d) postpone the date on which any interest or any fees are payable, other
than interest imposed by subsection 2.2D for a period not to exceed 60 days,

(e) decrease the interest rate or stamping fee borne by any Loan or the
amount of any fees payable hereunder, other than interest imposed by
subsection 2.2D for a period not to exceed 60 days,

(f) reduce the amount or postpone the due date of any amount payable in
respect of any Letter of Credit,

(g) extend the expiration date of any Letter of Credit beyond the Revolving
Loan Commitment Termination Date,

(h) change in any manner the obligations of Revolving Lenders relating to
the purchase of participations in Letters of Credit, or

(i) increase such Lender’s Revolving Loan Commitment;

     (ii) without the consent of all Lenders:

(a) change in any manner the definition of “Pro Rata Share” or the
definition of “Requisite Lenders” (except for any changes resulting solely
from an increase in Revolving Loan Commitments approved by Requisite
Lenders),

(b) change in any manner any provision of this Agreement that, by its terms,
expressly requires the approval or concurrence of all Lenders,

(c) increase the maximum duration of BA Interest Periods permitted
hereunder,

(d) release any Lien granted in favor of Collateral Agent with respect to
the Collateral, or release Holdings from its obligations under the Holdings
Guarantee, or release any of the Subsidiary Guarantors from their
obligations under the Subsidiary Guarantee, in each case other than in
accordance with the terms of this Agreement and the other Loan Documents,
including subsections 12.14 and 12.15, or

(First Amended and Restated Credit Agreement)

- 136 -

 

(e) change in any manner or waive the provisions contained in subsection
10.1 or this subsection 12.6.

     In addition:

     (1) no amendment, modification, termination or waiver of any provision
of subsection 2.1A(ii) or of any other provision of this Agreement relating
to the Swing Line Loan Subcommitment or the Swing Line Loans shall be
effective without the written concurrence of Swing Line Lender,

     (2) no amendment, modification, termination or waiver of any provision
of Section 4 shall be effective without the written concurrence of Fronting
Bank (if any) and, with respect to Letters of Credit, without the written
concurrence of each Issuing Lender that has issued an outstanding Letter of
Credit or has not been reimbursed for a payment under a Letter of Credit,

     (3) no amendment, modification, termination or waiver of any provision
of Section 11 or of any other provision of this Agreement which, by its
terms, expressly requires the approval or concurrence of Administrative
Agent or Collateral Agent shall be effective without the written concurrence
of Administrative Agent or Collateral Agent, as applicable; and

     (4) no amendment, modification, termination or waiver of Section 2.4F
affecting the rights thereunder of any Swap Lender shall be effective
without the written concurrence of such Swap Lender.

          Either Administrative Agent or Collateral Agent may, but shall have no obligation to, with the
concurrence of any Lender, execute amendments, modifications, waivers or consents on behalf of that
Lender. If Administrative Agent or Collateral Agent expressly executes any such amendment,
modification, waiver or consent on behalf of any Lender or Lenders, Company may rely on such
execution as conclusive evidence that the written concurrence of the Lender or Lenders on whose
behalf such Agent has executed has been obtained.

          Any waiver or consent shall be effective only in the specific instance and for the specific
purpose for which it was given. No notice to or demand on Company in any case shall entitle
Company to any other or further notice or demand in similar or other circumstances. Any amendment,
modification, termination, waiver or consent effected in accordance with this subsection 12.6 shall
be binding upon each Lender at the time outstanding, each future Lender and, if signed by Company,
on Company and each Subsidiary Guarantor.

     12.7 Independence of Covenants.

(First Amended and Restated Credit Agreement)

- 137 -

 

          All covenants hereunder shall be given independent effect so that if a particular action or
condition is not permitted by any of such covenants, the fact that it would be permitted by an
exception to, or would otherwise be within the limitations of, another covenant shall not avoid the
occurrence of an Event of Default or Potential Event of Default if such action is taken or
condition exists.

     12.8 Notices; Effectiveness of Signatures.

          Unless otherwise specifically provided herein, any notice or other communication herein
required or permitted to be given shall be in writing and may be personally served, or sent by
telefacsimile or Canadian mail or courier service and shall be deemed to have been given when
delivered in person or by courier service, upon receipt of telefacsimile in complete and legible
form, or three Business Days after depositing it in the Canadian mail with postage prepaid and
properly addressed, provided that notices to Administrative Agent, Collateral Agent, Swing
Line Lender and any Issuing Lender shall not be effective until received. For the purposes hereof,
the address of each party hereto shall be as set forth under such party’s name on the signature
pages hereof or (i) as to Company, Collateral Agent and Administrative Agent, such other address as
shall be designated by such Person in a written notice delivered to the other parties hereto and
(ii) as to each other party, such other address as shall be designated by such party in a written
notice delivered to Administrative Agent, Collateral Agent and Company. Electronic mail and
Internet and intranet websites may be used to distribute routine communications, such as financial
statements and other information, provided that no signature with respect to any notice,
request, agreement, waiver, amendment or other document or any notice that is intended to have
binding effect may be sent by electronic mail.

          Loan Documents and notices under the Loan Documents may be transmitted and/or signed by
telefacsimile. The effectiveness of any such documents and signatures shall, subject to Applicable
Law, have the same force and effect as an original copy with manual signatures and shall be binding
on all Loan Parties, Agents and Lenders. Agents may also require that any such documents and
signature be confirmed by a manually-signed copy thereof, provided that the failure to
request or deliver any such manually-signed copy shall not affect the effectiveness of any
facsimile document or signature.

     12.9 Survival of Representations, Warranties and Agreements.

     A. Survive Execution. All representations, warranties and agreements made herein shall
survive the execution and delivery of this Agreement and the making of the Loans and the issuance
of the Letters of Credit hereunder.

     B. Survive Termination. Notwithstanding anything in this Agreement or implied by Applicable
Law to the contrary, the agreements of Company set forth in subsections 2.6, 12.2, 12.3, 12.18 and
12.19 and the agreements of Lenders set forth in subsections 11.2C, 11.4, 12.5, 12.19 and 12.20
shall survive the payment of the Loans, the cancellation or expiration of the Letters of Credit and
the reimbursement of any amounts drawn thereunder, and the termination of this Agreement.

(First Amended and Restated Credit Agreement)

- 138 -

 

     12.10 Failure or Indulgence Not Waiver; Remedies Cumulative.

          No failure or delay on the part of an Agent or any Lender in the exercise of any power, right
or privilege hereunder or under any other Loan Document shall impair such power, right or privilege
or be construed to be a waiver of any default or acquiescence therein, nor shall any single or
partial exercise of any such power, right or privilege preclude other or further exercise thereof
or of any other power, right or privilege. All rights and remedies existing under this Agreement
and the other Loan Documents are cumulative to, and not exclusive of, any rights or remedies
otherwise available.

     12.11 Marshalling; Payments Set Aside.

          Neither any Agent nor any Lender shall be under any obligation to marshal any assets in favor
of Company or any other party or against or in payment of any or all of the Obligations. To the
extent that Company makes a payment or payments to Administrative Agent or Lenders (or to
Administrative Agent for the benefit of Lenders), or Agents or Lenders enforce any security
interests or exercise their rights of setoff, and such payment or payments or the proceeds of such
enforcement or setoff or any part thereof are subsequently invalidated, declared to be fraudulent
or preferential, set aside and/or required to be repaid to a trustee, receiver or any similar
official in respect of a Loan Party under any Bankruptcy Law, any other state or federal law,
common law or any equitable cause, then, to the extent of such recovery, the obligation or part
thereof originally intended to be satisfied, and all Liens, rights and remedies therefor or related
thereto, shall be revived and continued in full force and effect as if such payment or payments had
not been made or such enforcement or setoff had not occurred.

     12.12 Severability.

          In case any provision in or obligation under this Agreement shall be invalid, illegal or
unenforceable in any jurisdiction, the validity, legality and enforceability of the remaining
provisions or obligations, or of such provision or obligation in any other jurisdiction, shall not
in any way be affected or impaired thereby.

     12.13 Obligations Several; Independent Nature of Lenders’ Rights; Damage Waiver.

          The obligations of Lenders hereunder are several and no Lender shall be responsible for the
obligations or Revolving Loan Commitments of any other Lender hereunder. Nothing contained herein
or in any other Loan Document, and no action taken by Lenders pursuant hereto or thereto, shall be
deemed to constitute Lenders, or Lenders and Company, as a partnership, an association, a Joint
Venture or any other kind of entity. The amounts payable at any time hereunder to each Lender shall
be a separate and independent debt, and each Lender shall be entitled to protect and enforce its
rights arising out of this Agreement and it shall not be necessary for any other Lender to be
joined as an additional party in any proceeding for such purpose.

          This Agreement and any amendments, waivers, consents or supplements hereto or in connection
herewith may be executed in any number of counterparts and by different parties hereto in separate
