     For purposes of determining the Applicable Margin, the US Borrowers’
initial Index Debt Rating will be Category 3. If the Index Debt Ratings
established or deemed to have been established by Moody’s and S&P shall fall
within different Categories, the Applicable Margin shall be based (i) if the
differential is one level, the lower number of the Categories, or (ii) if the
differential is more than one level, the Category number immediately higher than
the lowest. If the Index Debt Ratings established or deemed to have been
established by Moody’s and S&P shall be changed (other than as a result of a
change in the rating system of Moody’s or S&P), such change shall be effective
as of the date on which it is first announced by the applicable rating agency,
irrespective of when notice of such change shall have been furnished by Holdings
to the US Administrative Agent pursuant to Section 9.01 or otherwise. Each
change in the Applicable Margin shall apply during the period commencing on the
effective date of such change and ending on the date immediately preceding the
effective date of the next such change. If the rating system of Moody’s or S&P
shall change, or if either such rating agency shall cease to be in the business
of rating corporate debt obligations, Holdings and the US Tranche Revolving
Lenders shall negotiate in good faith to amend this definition to reflect such
changed rating system or the unavailability of ratings from such rating agency
and, pending the effectiveness of any such amendment, the Applicable Margin
shall be determined by reference to the rating of such agency most recently in
effect prior to such change or cessation. For purposes of the foregoing, if both

          (b) Letters of Credit. During the period from and including the

Credit having an expiration date extending beyond the Revolving Credit Maturity

          (c) Notices. The initial Borrowing and all subsequent Borrowings,
continuations and conversions shall require advance written notice to the US
Administrative Agent (which shall promptly notify the Lenders including the

Dollar LIBO Rate Borrowing may be continued as provided herein, provided that

have occurred and be continuing. If a Default shall have occurred and be
continuing, each US Dollar LIBO Rate Borrowing shall be converted to a US Dollar
Base Rate Borrowing on the last day of the Interest Period applicable thereto.
          (e) Conversion Options. The Borrowers may elect to convert all or any
part of any US Dollar LIBO Rate Borrowing on the last day of the then current
Interest Period relating thereto to (i) for the US Tranche, a US Dollar Base
Rate Borrowing and (ii) for the Canadian Tranche, a US Dollar Base Rate
Borrowing, a Canadian Prime Rate Borrowing or (subject to Section 2.12) a
Bankers’ Acceptance or BA Equivalent Loan Borrowing by giving advance notice to
the US Administrative Agent (which shall promptly notify the Lenders including
the Canadian Administrative Agent) of such election. Subject to the provisions
made in this Section 2.02(e), the Borrowers may elect to convert all or any part
of any US Dollar Base Rate Borrowing at any time and from time to time to
(A) for the US Tranche, a US Dollar LIBO Rate Borrowing and (B) for the Canadian
Tranche, a US Dollar LIBO Rate Borrowing, a Canadian Prime Rate Borrowing or
(subject to Section 2.12) a Bankers’ Acceptance or BA Equivalent Loan Borrowing
by giving advance notice as provided in Section 2.02(c) to the US Administrative
Agent (which shall promptly notify the Lenders including the Canadian
Administrative Agent) of

-35-

--------------------------------------------------------------------------------

 

such election. All or any part of any outstanding Borrowing may be converted as
provided herein, provided that (x) any conversion of any US Dollar Base Rate
Borrowing into a US Dollar LIBO Rate Borrowing shall be (as to each such
Borrowing into which there is a conversion for an applicable Interest Period) in
amounts of at least $1,000,000 or any whole multiple of $500,000 in excess
thereof and (y) no Default shall have occurred and be continuing. If a Default
shall have occurred and be continuing, no US Dollar Base Rate Borrowing may be
converted into a US Dollar LIBO Rate Borrowing.
          (f) Advances. Not later than 1:00 p.m. Eastern time on the date
specified for each Borrowing hereunder, each Applicable Lender shall make
available the amount of the Loan to be made by it on such date to the Applicable
Administrative Agent, to an account which such Administrative Agent shall
specify, in immediately available funds, for the account of the Requesting
Borrower. The amounts so received by the Applicable Administrative Agent shall,
subject to the terms and conditions of this Agreement, be made available to the
Requesting Borrower by depositing the same, in immediately available funds, in
an account of the Requesting Borrower, designated by such Borrower and
maintained at its principal office.
          (g) Letters of Credit. Any US Borrower shall submit to the US
Administrative Agent and the Issuing Bank a Letter of Credit Application not
later than 11:00 a.m. Eastern time, not less than three (3) Business Days prior
to the proposed date of issuance (or such shorter period as may be agreed to by
the US Administrative Agent and the Issuing Bank) and at least thirty (30)
Business Days prior to the date of amendment, renewal or extension (or such
shorter period as may be agreed to by the US Administrative Agent and the
Issuing Bank) of a Letter of Credit hereunder. Each Letter of Credit Application
shall specify (i) the amount of such Letter of Credit, (ii) the date (which
shall be a Business Day) such Letter of Credit is to be issued, amended, renewed
or extended, (iii) the duration thereof, (iv) the name and address of the
beneficiary thereof, (v) the form of the Letter of Credit, (vi) the name of the
elected Issuing Bank and (vii) such other information as the US Administrative
Agent and the Issuing Bank may reasonably request, all of which shall be
reasonably satisfactory to the US Administrative Agent and such Issuing Bank.
Subject to the terms and conditions of this Agreement, on the date specified for
the issuance, amendment, renewal or extension of a Letter of Credit, the Issuing
Bank shall issue, amend, renew or extend such Letter of Credit to the
beneficiary thereof. Promptly thereafter, the Issuing Bank shall notify the US
Administrative Agent and the applicable US Borrower, in writing, of such
issuance, amendment, renewal or extension, and such notice shall be accompanied
by a copy of such issuance, amendment, renewal or extension. Promptly after
receipt of such notice, the US Administrative Agent shall notify each US Tranche
Revolving Lender, in writing, of such issuance, amendment, renewal or extension
and if any US Tranche Revolving Lender so requests, the US Administrative Agent
shall provide such Lender with copies of such issuance, amendment, renewal or
extension.
     Section 2.03 Changes of Commitments.
          (a) Upon (i) any sale of LP Units, Subordinated Units, IDRs or GP
Interests pursuant to Section 10.14(f), or (ii) any sale, exchange or conveyance
of Compression Assets to the UCLP Group resulting in cumulative Net Proceeds
exceeding $100,000,000 pursuant to Section 10.14(b), the Aggregate US Tranche
Commitments shall automatically reduce by an amount equal to 50% of the Net
Proceeds from such sale, exchange or conveyance, such amount to be set forth in
reasonable detail in an officer’s certificate of Holdings delivered promptly or

-36-

--------------------------------------------------------------------------------

 

within five (5) Business Days after the effectiveness of such sale, exchange or
conveyance; provided, however that any sale of LP Units as a result of an
over-allotment option pursuant to a public offering will not be considered a
sale that would result in a reduction to the Aggregate US Tranche Commitments.
          (b) The US Borrowers shall have the right to terminate or to reduce
the amount of the Aggregate US Tranche Commitments at any time, or from time to
time, upon not less than three (3) Business Days’ prior notice to the US
Administrative Agent (which shall promptly notify the Lenders including the
Canadian Administrative Agent) of each such termination or reduction, which
notice shall specify the effective date thereof and the amount of any such
reduction (which shall not be less than $1,000,000 or any whole multiple of
$500,000 in excess thereof) and shall be irrevocable and effective only upon
receipt by the US Administrative Agent; provided that, any termination in full
of the Aggregate US Tranche Commitments pursuant to Section 2.03(b) shall
automatically terminate in full the Canadian Allocated Maximum Total
Commitments.
          (c) The US Borrowers shall have the right to allocate (or reallocate,
if previously allocated) a portion of the Aggregate US Tranche Commitments as
the Canadian Allocated Total Commitments by notice to the US Administrative
Agent; provided that (i) any such notice shall be received by the US
Administrative Agent not later than 11:00 a.m. Eastern time ten (10) Business
Days prior to the date such allocation or reallocation shall become effective
which effective date may only occur six (6) times per calendar year, (ii) any
such allocation or reallocation shall be in an aggregate amount of $5,000,000 or
any whole multiple in excess thereof and after giving effect thereto, the
Canadian Allocated Total Commitments shall not exceed the Canadian Allocated
Maximum Total Commitments, or shall be a reallocation to zero, (iii) outstanding
US Tranche Loans will be reallocated according to the new US Tranche Percentages
and if outstanding US Dollar LIBOR Loans are required to be terminated, the
Borrowers shall pay any required amounts pursuant to Section 5.01 and
Section 2.04(a), and (iv) the US Borrowers shall not allocate or reallocate any
portion of the Aggregate US Tranche Commitments if, after giving effect thereto
and to any concurrent prepayments hereunder (A) the US Tranche Credit Exposure
would exceed the Aggregate US Tranche Commitments, (B) the Canadian Tranche
Credit Exposure would exceed the Canadian Allocated Total Commitments and
(C) any US Tranche Revolving Lender’s US Tranche Commitment would not equal or
exceed its US Tranche Credit Exposure or any Canadian Tranche Revolving Lender’s
Canadian Allocated Commitment would not equal or exceed its Canadian Tranche
Credit Exposure. The allocation will be effected by reducing the US Tranche
Commitment of each US Tranche Revolving Lender that is or has a branch or an
Affiliate that is a Canadian Tranche Revolving Lender by the amount that its or
its branch’s or Affiliate’s Canadian Allocated Commitment is increased. For any
reallocation, its or its branch’s or Affiliate’s Canadian Allocated Commitment
will be reduced by the amount that its US Tranche Commitment is increased. Any
US Tranche Revolving Lender that is not or has no branch or Affiliate that is a
Canadian Tranche Revolving Lender will not have its US Tranche Commitment
affected. The US Administrative Agent will (x) promptly notify the Canadian
Administrative Agent and the US Tranche Revolving Lenders and the Canadian
Tranche Revolving Lenders of any such notice of allocation or reallocation of
the Aggregate US Tranche Commitments and the amount of their respective Canadian
Allocated Commitments, (y) prepare and provide to the Borrowers, the Canadian
Administrative Agent and the other Lenders such documentation reflecting the new
US

-37-

--------------------------------------------------------------------------------

 

Tranche Commitments and Canadian Allocated Commitments giving effect to such
allocation or reallocation and (z) notify all Lenders of the Aggregate US
Tranche Commitments and Canadian Allocated Total Commitments upon the
effectiveness of such allocation or reallocation, which effectiveness shall
require no vote or consent of any Lender.
          (d) At any time during which no Canadian Allocation Period exists, the
US Borrowers may at such time permanently terminate their right to allocate a
portion of the Aggregate US Tranche Commitments as the Canadian Allocated Total
Commitments, at which time the obligations of the Canadian Borrowers hereunder
and each Guaranty pursuant to ARTICLE XIV shall automatically terminate, and
thereafter no US Tranche Revolving Lender nor any Canadian Tranche Revolving
Lender shall have any Canadian Allocated Commitment.
          (e) The Aggregate US Tranche Commitments once terminated or reduced
pursuant to Sections 2.03(a) and (b), respectively may not be reinstated except
pursuant to Section 2.15.
     Section 2.04 Fees.
          (a) Commitment Fees.
     (i) The US Borrowers shall pay to the US Administrative Agent for the
account of each US Tranche Revolving Lender a commitment fee, which shall accrue
at the Applicable Margin (a “US Commitment Fee”), on the daily average unused
amount (after deducting any LC Exposure) of each US Tranche Revolving Lender’s
US Tranche Commitment for the period from and including the Closing Date up to,
but excluding, the Revolving Credit Maturity Date.
     (ii) During a Canadian Allocation Period, in consideration of each Canadian
Tranche Revolving Lender’s Canadian Allocated Commitment, the Canadian Borrowers
shall pay to the US Administrative Agent in US Dollars for the account of each
Canadian Tranche Revolving Lender a commitment fee, which shall accrue at the
Applicable Margin (a “Canadian Commitment Fee”), on the daily average unused
amount of each Canadian Tranche Revolving Lender’s Canadian Allocated Commitment
for the Canadian Allocation Period.
     (iii) Accrued Commitment Fees shall be payable quarterly in arrears on each
Quarterly Date, on the date of any reallocation of the Aggregate US Tranche
Commitments under Section 2.03(c) and on the earlier of the date the Aggregate
Revolving Commitments are terminated or the Revolving Credit Maturity Date.
          (b) Letter of Credit Fees.
     (i) The US Borrowers shall pay to the US Administrative Agent, for the
account of each US Tranche Revolving Lender and the Issuing Banks, commissions
for issuing the Letters of Credit on the daily outstanding amount of the maximum
liability of the Issuing Banks existing from time under such Letter of Credit
(including the US Dollar Equivalent of the face amount of the outstanding
Offshore Currency Letter of Credit) (calculated separately for each Letter of
Credit) at a rate equal to the Applicable Margin

-38-

--------------------------------------------------------------------------------

 

for US Dollar LIBOR Loans under the Revolving Credit Facility, in effect from
time to time during the term of each Letter of Credit. Each Letter of Credit
shall be deemed outstanding up to the available face amount of the Letter of
Credit (including the US Dollar Equivalent of the face amount of the outstanding
Offshore Currency Letter of Credit) until the Issuing Banks have received from
the beneficiary a written cancellation authorization, in form and substance
reasonably acceptable to the Issuing Banks or until the date the Letter of
Credit expires by its terms. Such commissions are payable quarterly in arrears
on each Quarterly Date and upon cancellation or expiration of each such Letter
of Credit.
     (ii) In addition to the fees described in Section 2.04(b)(i), the US
Borrowers shall pay to the Issuing Bank, for such Issuing Bank’s account, 0.125%
per annum of each such fee as an issuing fee.
     (iii) The US Borrowers shall pay to the Issuing Bank for its own account,
upon each drawing or payment under, issuance of, or amendment to, any Letter of
Credit, such amount as shall at the time of such event be the administrative
charge and reasonable out-of-pocket expenses which the Issuing Bank or its
Affiliate is generally imposing in connection with such occurrence with respect
to letters of credit.
          (c) Other Fees. The US Borrowers shall pay to the US Administrative
Agent for its own account such other fees as are set forth in the Fee Letter on
the dates specified therein to the extent not paid prior to the Closing Date.
     Section 2.05 Several Obligations. The failure of any Lender to make any
Loan to be made by it or to provide funds for disbursements or reimbursements
under Letters of Credit on the date specified therefor shall not relieve any
other Lender of its obligation to make its Loan or provide funds on such date,
but no Lender shall be responsible for the failure of any other Lender to make a
Loan to be made by such other Lender or to provide funds to be provided by such
other Lender.
     Section 2.06 Notes. Any Lender may request that the Loans made by it be
evidenced by a promissory note. In such event, the Applicable Borrower shall
prepare, execute and deliver to such Lender a promissory note payable to the
order of such Lender, substantially in the form of Exhibit A-1, with respect to
Revolving Loans made to the US Borrowers, Exhibit A-2 with respect to Revolving
Loans made to the Canadian Borrowers and Exhibit A-3 with respect to Term Loans,
as applicable, dated (a) the Closing Date or (b) the effective date of an
Assignment pursuant to Section 13.06(b), in a Principal Amount equal to its
Percentage Share of the Aggregate US Tranche Commitments, Canadian Allocated
Maximum Total Commitments or Aggregate Term Commitments as the case may be, as
originally in effect and otherwise duly completed and such substitute Notes as
required by Section 13.06(b); provided that promissory notes requested in
amounts less than $1,000,000 shall require the consent of the Applicable
Borrower, such consent not to be unreasonably withheld or delayed. The date,
amount, Type, interest rate and Interest Period of each Loan made by each
Lender, and all payments made on account of the principal thereof, shall be
recorded by such Lender on its books and maintained in accordance with its usual
practice. Failure to make such recordation shall not affect any Lender’s or any
Borrower’s rights or obligations in respect of such Loans.

-39-

--------------------------------------------------------------------------------

 

     Section 2.07 Prepayments.
          (a) Voluntary Prepayments. The Borrowers may prepay the US Dollar Base
Rate Loans and the Canadian Borrowers may prepay the Canadian Prime Rate Loans,
as applicable, upon the same Business Day’s prior notice to the US
Administrative Agent (which shall promptly notify the Lenders, including the
Canadian Administrative Agent), which notice shall specify the prepayment date
(which shall be a Business Day) and the amount of the prepayment (which shall be
at least $1,000,000 or the remaining aggregate principal balance outstanding on
the applicable Notes) and shall be irrevocable and effective only upon receipt
by the US Administrative Agent, provided that interest on the principal prepaid,
accrued to the prepayment date, shall be paid on the prepayment date. The
Borrowers may prepay US Dollar LIBOR Loans on the same conditions as for US
Dollar Base Rate Loans (except that prior notice to the US Administrative Agent
shall not be less than three (3) Business Days for US Dollar LIBOR Loans) and in
addition such prepayments of US Dollar LIBOR Loans shall be subject to the terms
of Section 5.05 and shall be in an amount equal to all of the US Dollar LIBOR
Loans for the Interest Period prepaid. Any prepayments made to the Term Loans
shall be applied inversely to the remaining installments owed. Notwithstanding
the foregoing, the Canadian Borrowers shall not be permitted to prepay any
Bankers’ Acceptances or BA Equivalent Loans at any time.
          (b) Mandatory Prepayments.
     (i) If, after giving effect to any termination, reduction or allocation of
the Aggregate US Tranche Commitments pursuant to Sections 2.03(a), (b) and (c),
(A) the US Tranche Credit Exposure exceeds the Aggregate US Tranche Commitments
or (B) any US Tranche Revolving Lender’s US Tranche Credit Exposure exceeds its
US Tranche Commitment, (1) the US Borrowers shall prepay the US Tranche Loans on
the date of such termination, reduction or allocation in an aggregate Principal
Amount, together with interest on the Principal Amount paid accrued to the date
of such prepayment, equal to the excess to be applied first to clause (A) above
and then any remaining to clause (B) above for the applicable US Tranche
Revolving Lender and (2) if any excess remains after prepaying all of the US
Tranche Loans because of the LC Exposure, the US Borrowers shall pay to the US
Administrative Agent on behalf of the Issuing Bank and the US Tranche Revolving
Lenders an amount equal to the excess to be held as cash collateral as provided
in Section 2.10(b) hereof.
     (ii) If, after giving effect to any reallocation of the Canadian Allocated
Commitment pursuant to Section 2.03(c) or any termination or reduction pursuant
to Section 2.03(b), (A) the outstanding aggregate Principal Amount of the
Canadian Tranche Credit Exposure exceeds the Canadian Allocated Total
Commitments or (B) any Canadian Tranche Revolving Lender’s Canadian Tranche
Credit Exposure exceeds its Canadian Allocated Commitment, the Canadian
Borrowers shall prepay the Canadian Tranche Loans (other than Bankers’
Acceptances and BA Equivalent Loans) on the date of such reallocation in an
aggregate Principal Amount, together with interest on the Principal Amount paid
accrued to the date of such prepayment equal to the excess to be applied first
to clause (A) above and then any remaining to clause (B) above for the
applicable Canadian Tranche Revolving Lender.

-40-

--------------------------------------------------------------------------------

 

          (c) Generally. Prepayments permitted or required under this
Section 2.07 shall be without premium or penalty, except as required under
Section 5.05 for prepayment of US Dollar LIBOR Loans. Any prepayments on the
Revolving Loans may be reborrowed subject to the then effective Aggregate US
Tranche Commitments and the Canadian Allocated Total Commitments, as applicable.
Any prepayments on the Term Loans may not be reborrowed. Notwithstanding Section
2.07(b), any prepayments made if an Event of Default exists and is continuing
shall be applied pari passu to the Aggregate Credit Exposure. In the event of a
mandatory prepayment pursuant to this Section 2.07 which would cause Bankers’
Acceptances and BA Equivalent Notes to be prepaid but for the prohibition on
prepayment contained herein, the US Administrative Agent shall deposit with the
Canadian Administrative Agent an amount equal to the Principal Amount that would
have been prepaid for such Bankers’ Acceptances and BA Equivalent Notes on
behalf of the Canadian Tranche Revolving Lenders holding such Bankers’
Acceptances and BA Equivalent Notes to be held pursuant to the terms in
Section 2.12(i) except that on the BA Maturity Date for such Bankers’
Acceptances and BA Equivalent Notes, the Canadian Administrative Agent shall
apply such amounts against such Bankers’ Acceptances and BA Equivalent Notes.
     Section 2.08 Reserved.
     Section 2.09 Assumption of Risks. Each US Borrower assumes all risks of the
acts or omissions of any beneficiary of any Letter of Credit or any transferee
thereof with respect to its use of such Letter of Credit. Neither the Issuing
Bank (except in the case of gross negligence or willful misconduct on the part
of the Issuing Bank or any of its officers, employees, agents or representatives
as determined by final and non appealable judgment of a court of competent
jurisdiction), its correspondents nor any Lender shall be responsible for the
validity, sufficiency or genuineness of certificates or other documents or any
endorsements thereon, even if such certificates or other documents should in
fact prove to be invalid, insufficient, fraudulent or forged; for errors,
omissions, interruptions or delays in transmissions or delivery of any messages
by mail, telex, or otherwise, whether or not they be in code; for errors in
translation or for errors in interpretation of technical terms; the validity or
sufficiency of any instrument transferring or assigning or purporting to
transfer or assign any Letter of Credit or the rights or benefits thereunder or
proceeds thereof, in whole or in part, which may prove to be invalid or
ineffective for any reason; the failure of any beneficiary or any transferee of
any Letter of Credit to comply fully with conditions required in order to draw
upon any Letter of Credit; or for any other consequences arising from causes
beyond the Issuing Bank’s control or the control of the Issuing Bank’s
correspondents. In addition, neither the Issuing Bank, the US Administrative
Agent nor any Lender shall be responsible for any error, neglect, or default of
any of the Issuing Bank’s correspondents; and none of the above shall affect,
impair or prevent the vesting of any of the Issuing Bank’s, the US
Administrative Agent’s or any Lender’s rights or powers hereunder, all of which
rights shall be cumulative. The Issuing Bank and its correspondents may accept
certificates or other documents that appear on their face to be in order,
without responsibility for further investigation of any matter contained therein
regardless of any notice or information to the contrary. In furtherance and not
in limitation of the foregoing provisions, each US Borrower agrees that any
action, inaction or omission taken or not taken by the Issuing Bank or by any
correspondent for the Issuing Bank in good faith in connection with any Letter
of Credit, or any related drafts, certificates, documents or instruments, shall
be binding on the

-41-

--------------------------------------------------------------------------------

 

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

-42-

--------------------------------------------------------------------------------

 

Letter of Credit; and (F) any other circumstance or happening whatsoever,
whether or not similar to any of the foregoing.
Notwithstanding anything in this Agreement to the contrary, the US Borrowers
will not be liable for payment or performance that results from the gross
negligence or willful misconduct of the Issuing Bank or its officers, employees,
agents or representatives, except where the US Borrowers or any Restricted
Subsidiary actually recovers the proceeds for itself or the Issuing Bank of any
payment made by the Issuing Bank in connection with such gross negligence or
willful misconduct, except for reasonable costs and expenses associated with
such recovery.
          (b) In the event of the occurrence of any Event of Default, a payment
or prepayment pursuant to Section 2.07(b) or the maturity of the Notes, whether
by acceleration or otherwise, an amount equal to the LC Exposure, except for all
Offshore Currency Letters of Credit which shall equal an amount equal to 110% of
the aggregate face amount of all such Offshore Currency Letters of Credit based
on the then US Dollar Equivalent, shall be deemed to be forthwith due and owing
by the US Borrowers to the Issuing Bank, the US Administrative Agent and the US
Tranche Revolving Lenders as of the date of any such occurrence; and each US
Borrower’s obligation to pay such amount shall be absolute and unconditional,
without regard to whether any beneficiary of any such Letter of Credit has
attempted to draw down all or a portion of such amount under the terms of a
Letter of Credit, and, to the fullest extent permitted by applicable law, shall
not be subject to any defense or be affected by a right of set-off, counterclaim
or recoupment which the US Borrowers may now or hereafter have against any such
beneficiary, the Issuing Bank, the US Administrative Agent, the US Tranche
Revolving Lenders or any other Person for any reason whatsoever. The US
Borrowers will have a continuing obligation to maintain in such account at least
an amount in cash equal to 110% of the aggregate face amount of all such
Offshore Currency Letters of Credit based on the then US Dollar Equivalent. Such
payments shall be held by the Issuing Bank on behalf of the US Tranche Revolving
Lenders as cash collateral securing the LC Exposure in an account or accounts at
the Principal Office; and the US Borrowers hereby grant to, and by their deposit
with the US Administrative Agent grants to, the US Administrative Agent a
security interest in such cash collateral. In the event of any such payment by
the US Borrowers of amounts contingently owing under outstanding Letters of
Credit and in the event that thereafter drafts or other demands for payment
complying with the terms of such Letters of Credit are not made prior to the
respective expiration dates thereof, the US Administrative Agent agrees, if no
Event of Default has occurred and is continuing or if no other amounts are
outstanding under this Agreement, the Notes or the Security Instruments, to
remit to the US Borrowers (i) amounts for which the contingent obligations
evidenced by the Letters of Credit have ceased and (ii) amounts on deposit as
cash collateral for Letters of Credit.
          (c) Each US Tranche Revolving Lender severally and unconditionally
agrees that it shall promptly reimburse the Issuing Bank in US Dollars an amount
equal to such Lender’s participation in any Letter of Credit as provided in
Section 2.01(b) of any disbursement made by the Issuing Bank under any Letter of
Credit that is not reimbursed according to this Section 2.10 (other than with
respect to disbursements described in the second paragraph of Section 2.10(a)),
and such obligation to reimburse is absolute and unconditional and shall not be
affected by any circumstance whatsoever, including any amendment, renewal or
extension of any Letter of Credit or the occurrence and continuance of a Default
or reduction or termination of the

-43-

--------------------------------------------------------------------------------

 

Aggregate Revolving Commitments, and that each such payment shall be made
without any offset, abatement, withholding or reduction whatsoever. If the US
Borrowers fail to make such payment when due, the US Administrative Agent shall
notify each US Tranche Revolving Lender of the applicable disbursement, the
payment then due from the US Borrowers in respect thereof and such Lender’s
applicable percentage thereof. Promptly following receipt of such notice, each
US Tranche Revolving Lender shall pay to the US Administrative Agent its
applicable percentage of the payment then due from the US Borrowers, in the same
manner as provided in Section 2.02(f) with respect to Loans made by such Lender
(and Section 2.02(f) shall apply, mutatis mutandis, to the payment obligations
of the US Tranche Revolving Lenders), and the US Administrative Agent shall
promptly pay to the Issuing Bank the amounts so received by it from the US
Tranche Revolving Lenders. Promptly following receipt by the US Administrative
Agent of any payment from the US Borrowers pursuant to this paragraph, the US
Administrative Agent shall distribute such payment to the Issuing Bank or, to
the extent that US Tranche Revolving Lenders have made payments pursuant to this
paragraph to reimburse the Issuing Bank, then to such US Tranche Revolving
Lenders and the Issuing Bank as their interests may appear. Any payment made by
a Lender pursuant to this paragraph to reimburse the Issuing Bank for any
disbursement shall constitute a Loan and shall not relieve the US Borrowers of
their obligation to reimburse such disbursement.
          (d) If no Event of Default has occurred and is continuing, and subject
to availability under the Aggregate Revolving Commitments (after reduction for
the LC Exposure), to the extent the US Borrowers have not reimbursed the Issuing
Bank for any drawn upon Letter of Credit within one (1) Business Day after
notice of such disbursement has been received by the US Borrowers, the amount of
such Letter of Credit reimbursement obligation shall automatically be funded by
the US Tranche Revolving Lenders as a Loan hereunder and used to pay such Letter
of Credit reimbursement obligation in the percentages referenced in clause
(c) above. If an Event of Default has occurred and is continuing, or if the
funding of such Letter of Credit reimbursement obligation as a Loan would cause
the aggregate amount of all Loans outstanding to exceed the Aggregate Revolving

are not less than thirty (30) days or more than 180 days, from the Acceptance
Date (and shall in no event mature on a date after the Revolving Credit Maturity

Bankers’ Acceptance or BA Equivalent Loan be less than C$1,000,000 and other
than in multiples of C$100,000 for any amounts in excess thereof. Whenever the
Canadian Borrowers are required to furnish a notice to the Canadian
Administrative Agent pursuant to the following additional provisions of this
Section 2.12, it shall give a copy of such notice to the US Administrative
Agent.
          (b) To facilitate the acceptance of Bankers’ Acceptances and the

shall, from time to time as required, provide to the Canadian Administrative
Agent Drafts and BA Equivalent Notes duly executed and endorsed in blank by the
Canadian Borrowers in quantities sufficient for each Canadian Tranche Revolving
Lender to fulfill its obligations hereunder. In addition, the Canadian Borrowers
hereby appoint each Canadian Tranche Revolving Lender as its attorney, with
respect to Drafts and BA Equivalent Notes for which the Canadian Borrowers have
provided a Bankers’ Acceptance or BA Equivalent Loan notice:
     (i) to complete and sign on behalf of the Canadian Borrowers, either
manually or by facsimile or mechanical signature, the Drafts to create the
Bankers’ Acceptances (with, in each Canadian Tranche Revolving Lender’s
discretion, the inscription “This is a depository bill subject to the Depository
Bills and Notes Act (Canada)”) or the BA Equivalent Notes, as applicable;
     (ii) after the acceptance thereof by any Canadian Tranche Revolving Lender,
to endorse on behalf of the Canadian Borrowers, either manually or by facsimile
or mechanical signature, such Bankers’ Acceptance in favor of the applicable
purchaser or endorsee thereof including, in such Canadian Tranche Revolving
Lender’s discretion, such Canadian Tranche Revolving Lender or a clearing house
(as defined by the DBNA);
     (iii) to deliver such Bankers’ Acceptances to such purchaser or to deposit
such Bankers’ Acceptances with such clearing house; and
     (iv) to comply with the procedures and requirements established from time
to time by such Canadian Tranche Revolving Lender or such clearing house in
respect of the delivery, transfer and collection of Drafts and Bankers’
Acceptances.
The Canadian Borrowers recognize and agree that all Drafts, Bankers’ Acceptances
and BA Equivalent Notes signed, endorsed, delivered or deposited on their behalf
by a Canadian Tranche Revolving Lender shall bind the Canadian Borrowers as
fully and effectually as if signed in the handwriting of and duly issued,
delivered or deposited by the proper signing officer of such Canadian Borrower.
Each Canadian Tranche Revolving Lender is hereby authorized to accept such
Drafts or issue such Bankers’ Acceptances endorsed in blank or issue BA
Equivalent Notes in such face amounts as may be determined by such Canadian
Tranche Revolving Lender in accordance with the terms of this Agreement,
provided that the aggregate amount thereof is less than or equal to the
aggregate amount of Bankers’ Acceptances required to be accepted by or BA
Equivalent Loans made by such Canadian Tranche Revolving Lender. No Canadian
Tranche Revolving Lender shall be responsible or liable for its failure to
accept a Bankers’ Acceptance or make a BA Equivalent Loan if the cause of such
failure is, in whole or in part, due to the failure

-45-

--------------------------------------------------------------------------------

 

of the Canadian Borrowers to provide duly executed and endorsed Drafts or BA
Equivalent Notes to the Canadian Administrative Agent on a timely basis, nor
shall any Canadian Tranche Revolving Lender be liable for any damage, loss or
other claim arising by reason of any loss or improper use of any such instrument
except loss or improper use arising by reason of the gross negligence or willful
misconduct of such Canadian Tranche Revolving Lender, its officers, employees,
agents or representatives. The Canadian Administrative Agent and each Canadian
Tranche Revolving Lender shall exercise such care in the custody and safekeeping
of Drafts and BA Equivalent Notes as it would exercise in the custody and
safekeeping of similar property owned by it. Each Canadian Tranche Revolving
Lender will, upon the request of the Canadian Borrowers, promptly advise the
Canadian Borrowers of the number and designation, if any, of Drafts and BA
Equivalent Notes then held by it for the Canadian Borrowers. Each Canadian
Tranche Revolving Lender shall maintain a record with respect to Drafts and
Bankers’ Acceptances (A) received by it from the Canadian Administrative Agent
in blank hereunder, (B) voided by it for any reason, (C) accepted by it
hereunder, (D) purchased by it hereunder and (E) canceled at their respective
maturities and of BA Equivalent Notes (1) received by it from the Canadian
Administrative Agent in blank hereunder, (2) voided by it for any reason and
(3) canceled at their respective maturities. Each Canadian Tranche Revolving
Lender further agrees to retain such records in the manner and for the statutory
periods provided in the various Canadian provincial or federal statutes and
regulations which apply to such Canadian Tranche Revolving Lender.
          (c) When the Canadian Borrowers wish to make a Borrowing by way of
Bankers’ Acceptances or BA Equivalent Loans, such Canadian Borrower shall give
the Administrative Agents a borrowing notice in the form of Exhibit B-2 with
respect to the issuance of the Bankers’ Acceptances or BA Equivalent Notes by
not later than 1:00 p.m. Eastern time, three (3) Business Days’ prior to the
Acceptance Date. Each borrowing notice shall be irrevocable and binding on the
Canadian Borrowers. The Canadian Borrowers shall indemnify each Canadian Tranche
Revolving Lender against any loss or expense incurred by such Lender as a result
of any failure by the Canadian Borrowers to fulfill or honor before the date
specified as the Acceptance Date, the applicable conditions set forth in ARTICLE
VI, if, as a result of such failure the requested Bankers’ Acceptance or a BA
Equivalent Loan is not made on such date. Unless otherwise agreed among the
Administrative Agents and the Canadian Tranche Revolving Lenders, the aggregate
amount of all Bankers’ Acceptances or BA Equivalent Notes issued on any
Acceptance Date hereunder shall be accepted pro rata, subject to
Section 2.12(g), by all Canadian Tranche Revolving Lenders relative to their
respective Canadian Tranche Percentage. Upon receipt of a borrowing notice, the
Canadian Administrative Agent shall advise each Canadian Tranche Revolving
Lender of the contents thereof. Upon the acceptance of a Bankers’ Acceptance or
a BA Equivalent Note by a Canadian Tranche Revolving Lender, such Lender shall
purchase such Bankers’ Acceptance from or make such BA Equivalent Loan to such
Canadian Borrower and pay to the Canadian Administrative Agent not later than
12:00 p.m. Eastern time, on the day of such Borrowing, for the account of such
Canadian Borrower, the amount of the BA Net Proceeds in respect of such Bankers’
Acceptance or BA Equivalent Loan.
          (d) On each day during the period commencing with the issuance by the
Canadian Borrowers of any Bankers’ Acceptance and until such BA Exposure shall
have been paid by the Canadian Borrowers, the Canadian Allocated Commitment of
each Accepting Lender that is able to extend credit by way of Bankers’
Acceptances shall be deemed to be utilized for

-46-

--------------------------------------------------------------------------------

 

all purposes of this Agreement in an amount equal to the Principal Amount of
such Bankers’ Acceptance. The Canadian Allocated Commitment of any Canadian
Tranche Revolving Lender providing a BA Equivalent Loan rather than Bankers’
Acceptances shall be deemed utilized during this period in an amount equal to
its Canadian Tranche Percentage of the total amount of Bankers’ Acceptances and
BA Equivalent Loans in each borrowing notice.
          (e) The Canadian Borrowers agree to pay on the BA Maturity Date for
each Bankers’ Acceptance and BA Equivalent Note, to the Canadian Administrative
Agent for account of each Accepting Lender, an amount equal to the Principal
Amount of such Bankers’ Acceptance or BA Equivalent Note. The Canadian Borrowers
hereby waive presentment for payment of Bankers’ Acceptances or BA Equivalent
Note by each Accepting Lender and any defense to payment of amounts due to an
Accepting Lender in respect of a Bankers’ Acceptance or BA Equivalent Note which
might exist by reason of such Bankers’ Acceptance or BA Equivalent Note being
held at maturity by the Accepting Lender which accepted it and agree not to
claim from such Lender any days of grace for the payment at maturity of Bankers’
Acceptances or BA Equivalent Notes.
          (f) If the Canadian Borrowers fail to notify the Canadian
Administrative Agent in writing not later than 1:00 p.m. Eastern time, on the
Business Day prior to any BA Maturity Date that the Canadian Borrowers intend to
pay the Bankers’ Acceptances and BA Equivalent Loans due on such BA Maturity
Date, or fails to make such payment, the Canadian Borrowers shall be deemed, for
all purposes to have given the Canadian Administrative Agent notice of a
borrowing of a Canadian Prime Rate Loan pursuant to Section 2.02(a) for an
amount equal to the Principal Amount of such Bankers’ Acceptance and BA
Equivalent Loan; provided that:
     (i) the BA Maturity Date for such Bankers’ Acceptances shall be considered
to be the date of such Borrowing;
     (ii) the proceeds of such Canadian Prime Rate Loan shall be used to pay the
Principal Amount of the Bankers’ Acceptance due on such BA Maturity Date;
     (iii) each Canadian Tranche Revolving Lender which has made a maturing BA
Equivalent Loan (in accordance with Section 2.12(g) hereof) shall continue to
extend credit to such Canadian Borrower (without further advance of funds to
such Canadian Borrower) by way of a Canadian Prime Rate Loan in the Principal
Amount equal to its maturing BA Equivalent Loan; and
     (iv) the Canadian Administrative Agent shall promptly and in any event
within three (3) Business Days following the BA Maturity Date of such Bankers’
Acceptances and such BA Equivalent Loans, notify the Canadian Borrowers in
writing of the making of or converting to such Canadian Prime Rate Loan pursuant
to this Section 2.12(f).
          (g) If, in the sole judgment of a Canadian Tranche Revolving Lender,
such Lender is unable, as a result of applicable law, customary market practice,
or otherwise, to extend credit by way of Bankers’ Acceptances in accordance with
this Agreement, such Lender shall give notice to such effect to the Canadian
Administrative Agent and the Canadian Borrowers prior to 11:00 a.m. Eastern
time, on the date of the requested credit extension (which

-47-

--------------------------------------------------------------------------------

 

notice may, if so stated therein, remain in effect with respect to subsequent
requests for extension of credit by way of Bankers’ Acceptances until revoked by
notice to the Administrative Agents and the Canadian Borrowers) and shall make
available to the Canadian Administrative Agent, in accordance with this Section
2.12 hereof prior to 2:00 p.m. Eastern time, on the date of such requested
credit extension, a BA Equivalent Loan in an amount equal to the BA Net Proceeds
equivalent to such Lender’s Canadian Tranche Percentage of the total amount of
credit requested to be extended by way of Bankers’ Acceptances.
          (h) It is the intention of the Canadian Administrative Agent, the
Canadian Tranche Revolving Lenders, and the Canadian Borrowers that, except to
the extent a Canadian Tranche Revolving Lender advises otherwise, pursuant to
the DBNA, all Bankers’ Acceptances accepted by the Canadian Tranche Revolving
Lenders under this Agreement shall be issued in the form of a “depository bill”
(as defined in the DBNA), deposited with the Canadian Depository for Securities
Limited and made payable to CDS & Co.
          (i) If any Event of Default shall have occurred and be continuing, on
the Business Day that the Canadian Borrowers receive notice from the Canadian
Tranche Revolving Lenders with BA Exposure representing greater than 662/3% of
the total BA Exposure or, if the maturity of the Loans has been accelerated,
from the Canadian Administrative Agent, the US Administrative Agent, or the
Majority Lenders, demanding the deposit of cash collateral pursuant to this
paragraph, the Canadian Borrowers shall deposit in an account with the Canadian
Administrative Agent, in the name of the Canadian Administrative Agent and for
the benefit of the Canadian Tranche Revolving Lenders, an amount in cash equal
to the BA Exposure of the Canadian Borrowers as of such date plus any accrued
and unpaid interest thereon; provided that the obligation to deposit such cash
collateral shall become effective immediately, and such deposit shall become
immediately due and payable, without demand or other notice of any kind, upon
the occurrence of any Event of Default described in Section 11.01(f) or
Section 11.01(g). Any such deposit shall be held by the Canadian Administrative
Agent as collateral for the payment and performance of the obligations of the
Canadian Borrowers under this Agreement. The Canadian Administrative Agent shall
have exclusive dominion and control, including the exclusive right of
withdrawal, over such account. Other than any interest earned on the investment
of such deposits, which investments shall be made at the option and sole
discretion of the Canadian Administrative Agent and at the Canadian Borrowers’
risk and expense, such deposits shall not bear interest. Interest or profits, if
any, on such investments shall accumulate in such account. Moneys in such
account shall be applied by the Canadian Administrative Agent for the
satisfaction of the obligations of the Canadian Borrowers with respect to the BA
Exposure at such time or, if the maturity of the Loans has been accelerated, be
applied to satisfy other obligations of the Canadian Borrowers under this
Agreement (but subject to the consent of Canadian Tranche Revolving Lenders with
BA Exposure representing greater than 50% of the total BA Exposure). If the
Canadian Borrowers are required to provide an amount of cash collateral
hereunder as a result of the occurrence of an Event of Default, such amount (to
the extent not applied as aforesaid) shall be returned to the Canadian Borrowers
within three (3) Business Days after all Events of Default have been cured or
waived.
          (j) Drafts of the Canadian Borrowers to be accepted as Bankers’
Acceptances and BA Equivalent Notes hereunder shall be duly executed on behalf
of the Canadian Borrowers.

-48-

--------------------------------------------------------------------------------

 

Notwithstanding that any person whose signature appears on any Bankers’
Acceptance or BA Equivalent Note as a signatory for the Canadian Borrowers may
no longer be an authorized signatory for the Canadian Borrowers at the date of
issuance of a Bankers’ Acceptance or advance of a BA Equivalent Loan, 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 or advance, and any
such Bankers’ Acceptance or BA Equivalent Note so signed shall be binding on the
Canadian Borrowers.
          (k) Each Canadian Tranche Revolving 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.

          (a) Revolving Loans. On the Revolving Credit Maturity Date the
Borrowers shall pay to the Applicable Administrative Agent, for the account of
each Applicable Lender, the outstanding aggregate principal and accrued and
unpaid interest under the Revolving Loans.
          (b) Term Loans. On the Term Loan Maturity Date the US Borrowers shall
pay to the US Administrative Agent, for the account of each Term Loan Lender,
the outstanding aggregate principal and accrued and unpaid interest under the

     Section 3.02 Interest.
          (a) Interest Rates. The Borrowers will pay to the Applicable
Administrative Agent, for the account of each Applicable Lender, interest on the
unpaid Principal Amount of each Loan made by such Lender for the period
commencing on the date such Loan is made to, but excluding, the date such Loan
shall be paid in full, at the following rates per annum:
     (i) with respect to the Revolving Credit Facility, if such a Loan is a US
Dollar Base Rate Loan, the US Dollar Base Rate (as in effect from time to time)
plus the Applicable Margin, but in no event to exceed the Highest Lawful Rate;

-54-

--------------------------------------------------------------------------------

 

     (iv) with respect to the Term Loan Facility, if such Loan is a US Dollar
Base Rate Loan, the US Dollar Base Rate (as in effect from time to time) plus
the Applicable Margin, but in no event to exceed the Highest Lawful Rate; and
     (v) with respect to the Term Loan Facility, if such Loan is a US Dollar
LIBOR Loan, for each Interest Period relating thereto, the US Dollar LIBO Rate
for such Loan plus the Applicable Margin, but in no event to exceed the Highest
Lawful Rate.
          (b) Canadian Interest.
     (i) For purposes of disclosure under the Interest Act (Canada), where
interest is calculated pursuant Section 3.02(a)(iii) at a rate based upon a 360,
365 or 366 day year, as the case may be, (the “First Rate”), it is hereby agreed
that the rate or percentage of interest on a yearly basis is equivalent to such
First Rate multiplied by the actual number of days in the year divided by 360,
365 or 366, as applicable.
     (ii) Notwithstanding the provisions of this Section 3.02 or any other
provision of this Agreement, in no event shall the aggregate “interest” (as that
term is defined in Section 347 of the Criminal Code (Canada)) exceed the
effective annual rate of interest on the “credit advanced” (as defined therein)
lawfully permitted under Section 347 of the Criminal Code (Canada). The
effective annual rate of interest shall be determined in accordance with
generally accepted actuarial practices and principles over the term of the
applicable Canadian Tranche Loan, and in the event of a dispute, a certificate
of a Fellow of the Canadian Institute of Actuaries qualified for a period of ten
(10) years appointed by the Canadian Administrative Agent and approved by the
Canadian Borrowers, such approval shall not be unreasonably withheld or delayed,
will be conclusive for the purposes of such determination absent manifest error.
     (iii) A certificate of an authorized signing officer of the US
Administrative Agent as to each amount and/or each rate of interest payable
hereunder from time to time shall be conclusive evidence of such amount and of
such rate, absent manifest error.
     (iv) Wherever in this Agreement reference is made to a rate of interest
“per annum” or a similar expression is used, such interest shall be calculated
using the nominal rate method of calculation and shall not be calculated using
the effective rate method of calculation or any other basis that gives effect to
the principal of deemed reinvestment of interest.
          (c) Post-Default Rate. Notwithstanding the foregoing, each Borrower
will pay to the Applicable Administrative Agent, for the account of each
Applicable Lender interest at the applicable Post-Default Rate on any principal
of any Loan (excluding Bankers’ Acceptances and BA Equivalent Loans) made by
such Lender, and (to the fullest extent permitted by law) on any other amount
payable by each Borrower hereunder, under any Loan Document or under any Note
held by such Lender to or for account of such Lender, for the period commencing
on the date of an Event of Default until the same is paid in full or all Events
of Default are cured or waived.

-55-

--------------------------------------------------------------------------------

 

          (d) Due Dates. Accrued interest on US Dollar Base Rate Loans and
Canadian Prime Rate Loans shall be payable on each Quarterly Date, and accrued
interest on each US Dollar LIBOR Loan shall be payable on the last day of the
Interest Period therefor and, if such Interest Period is longer than three
months, at three-month intervals following the first day of such Interest
Period, except that interest payable at the Post-Default Rate shall be payable
from time to time on demand and interest on any US Dollar LIBOR Loan that is
converted into a US Dollar Base Rate Loan (pursuant to Section 5.04) shall be
payable on the date of conversion (but only to the extent so converted). Any
accrued and unpaid interest on the Revolving Loans shall be paid on the
Revolving Credit Maturity Date. Any accrued and unpaid interest on the Term
Loans shall be paid on the Term Loan Maturity Date.
          (e) Determination of Rates. Promptly after the determination of any
interest rate provided for herein or any change therein, the US Administrative
Agent shall notify the Lenders (including the Canadian Administrative Agent) to
which such interest is payable and the Applicable Borrower thereof. Each
determination by the US Administrative Agent of an interest rate or fee
hereunder shall, except in cases of manifest error, be final, conclusive and
binding on the parties.
ARTICLE IV
Payments; Pro Rata Treatment; Computations; Etc.
     Section 4.01 Payments. Except to the extent otherwise provided herein, all
payments of principal, interest and other amounts to be made by each Borrower
under this Agreement and the Notes shall be made in US Dollars in the case of US
Tranche Loans, and in Canadian Dollars or US Dollars, as the case may be, in the
case of Canadian Tranche Loans, in immediately available funds, to the
Applicable Administrative Agent at such account as such Applicable
Administrative Agent shall specify by notice to the Applicable Borrower from
time to time, not later than 1:00 p.m. Eastern time on the date on which such
payments shall become due (each such payment made after such time on such due
date to be deemed to have been made on the next succeeding Business Day). Such
payments shall be made without (to the fullest extent permitted by applicable
law) defense, set-off or counterclaim. Each such payment so received by the
Applicable Administrative Agent under this Agreement or any Note for account of
a Lender shall be paid promptly to such Lender in immediately available funds.
Except as otherwise provided in the definition of “Interest Period”, if the due
date of any payment under this Agreement or any Note would otherwise fall on a
day which is not a Business Day such date shall be extended to the next
succeeding Business Day and interest shall be payable for any principal so
extended for the period of such extension. At the time of each payment to the
Applicable Administrative Agent of any principal of or interest on any
Borrowing, the Applicable Borrower shall notify the Applicable Administrative
Agent of the Loans to which such payment shall apply. In the absence of such
notice, the Administrative Agents may specify the Loans to which such payment
shall apply, but to the extent possible such payment or prepayment will be
applied first to the Loans comprised of US Dollar Base Rate Loans or Canadian
Prime Rate Loans.
     Section 4.02 Pro Rata Treatment. Except to the extent otherwise provided
herein, each Lender agrees that: (a) each Borrowing from the Lenders under
Section 2.01 and each continuation and conversion under Section 2.02 shall be
made from the Applicable Lenders pro rata in accordance with their US Tranche
Percentages, Canadian Tranche Percentages or Term

-56-

--------------------------------------------------------------------------------

 

Loan Percentages, as the case may be, each payment of fees under Section 2.04
shall be made for account of the Applicable Lenders pro rata in accordance with
such same percentages; (b) each termination or reduction of the amount of the
Aggregate US Tranche Commitments under Section 2.03(b) shall be applied to the
US Tranche Commitment of each Applicable Lender, pro rata in accordance with its
US Tranche Percentage; (c) each allocation and reallocation of the Aggregate US
Tranche Commitments and the Canadian Allocated Commitments under Section 2.03(c)
shall be made for the account of each US Tranche Revolving Lender and each
Canadian Tranche Revolving Lender according to its respective Percentage Share;
(d) each payment of Commitment Fees under Section 2.04(a) shall be made to each
US Tranche Revolving Lender and Canadian Tranche Revolving Lender in accordance
with their respective Percentage Shares; (e) each payment or prepayment of
principal of Loans by each Borrower shall be made for account of the Applicable
Lenders pro rata in accordance with the respective unpaid Principal Amount of
the Loans held by the Applicable Lenders; (f) each payment of interest on Loans
by each Borrower shall be made for account of the Applicable Lenders pro rata in
accordance with the amounts of interest due and payable to the respective
Lenders; and (g) each reimbursement by the US Borrowers of disbursements under
Letters of Credit shall be made for account of the Issuing Bank or, if funded by
the US Tranche Revolving Lenders, pro rata for the account of the US Tranche
Revolving Lenders, in accordance with the amounts of reimbursement obligations
due and payable to each respective US Tranche Revolving Lender.
     Section 4.03 Computations. Interest on US Dollar LIBOR Loans and fees shall
be computed on the basis of a year of 360 days and actual days elapsed
(including the first day but excluding the last day) occurring in the period for
which such interest is payable, unless such calculation would exceed the Highest
Lawful Rate, in which case interest shall be calculated on the per annum basis
of a year of 365 or 366 days, as the case may be. Interest on US Dollar Base
Rate Loans shall be computed on the basis of a year of 365 or 366 days, as the
case may be, and actual days elapsed (including the first day but excluding the
last day) occurring in the period for which such interest is payable. Interest
on Canadian Prime Rate Loans shall be computed as provided in Section 3.02(b).
     Section 4.04 Agent Reliance. Unless the US Administrative Agent shall have
received notice from a Lender before the date of any Borrowing of the proceeds
of the Loan that such Lender will not make available to the Applicable
Administrative Agent such Lender’s Percentage Share of such advance, such
Applicable Administrative Agent may assume that such Lender has made its
Percentage Share of such Borrowing available to such Applicable Administrative
Agent on the date of such Borrowing in accordance with Section 2.02(c) and such
Applicable Administrative Agent may, in reliance upon such assumption, make
available to the Applicable Borrower on such date a corresponding amount. If and
to the extent that such Lender shall not have so made its Percentage Share of
such Borrowing available to such Applicable Administrative Agent, such Lender
agrees to immediately pay to such Applicable Administrative Agent on demand such
corresponding amount, together with interest on such amount, for each day from
the date such amount is made available to the Applicable Borrower until the date
such amount is paid to the Applicable Administrative Agent, at the overnight
Federal Funds Rate. If such Lender shall pay to the Applicable Administrative
Agent such corresponding amount and interest as provided above, such
corresponding amount so paid shall constitute such Lender’s advance as part of
such Borrowing for purposes of this Agreement even though not made on the same
day as the other advances comprising such Borrowing.

-57-

--------------------------------------------------------------------------------

 

     Section 4.05 Set-off, Sharing of Payments, Etc.
          (a) Each Borrower agrees that, in addition to (and without limitation
of) any right of set-off, bankers’ lien or counterclaim a Lender may otherwise
have, each Lender shall have the right and be entitled (after consultation with
the US Administrative Agent), at its option, to offset balances held by it or by
any of its Affiliates for account of the Applicable Borrower at any of its
offices, in US Dollars or in any other currency, against any principal of or
interest on any of such Lender’s Loans, or any other amount payable to such
Lender hereunder, which is not paid when due (including applicable grace
periods) (regardless of whether such balances are then due to such Borrower), in
which case it shall promptly notify the Applicable Borrower and the US
Administrative Agent thereof, provided that such Lender’s failure to give such
notice shall not affect the validity thereof.
          (b) If any Lender shall obtain payment of any principal of or interest
on any Loan made by it to a Borrower under this Agreement (or reimbursement as
to any Letter of Credit) through the exercise of any right of set-off, banker’s
lien or counterclaim or similar right or otherwise, and, as a result of such
payment, such Lender shall have received a greater percentage of the principal
or interest (or reimbursement) then due hereunder by the Applicable Borrower to
such Lender than the percentage received by any other Applicable Lenders, it
shall promptly (i) notify the US Administrative Agent and each other Lender
(including the Canadian Administrative Agent) thereof and (ii) purchase from
such other Applicable Lenders participations in (or, if and to the extent
specified by such Applicable Lender, direct interests in) the Loans (or
participations in Letters of Credit) made by such other Applicable Lenders (or
in interest due thereon, as the case may be) in such amounts, and make such
other adjustments from time to time as shall be equitable, to the end that all
the Applicable Lenders shall share the benefit of such excess payment (net of
any expenses which may be incurred by such Lender in obtaining or preserving
such excess payment) pro rata in accordance with the unpaid principal and/or
interest on the Loans held by each of the Applicable Lenders (or reimbursements
of Letters of Credit). To such end all the Applicable Lenders shall make
appropriate adjustments among themselves (by the resale of participations sold
or otherwise) if such payment is rescinded or must otherwise be restored. Each
Borrower agrees that any Lender so purchasing a participation (or direct
interest) in the Loans made by other Lenders (or in interest due thereon, as the
case may be) may exercise all rights of set-off, banker’s lien, counterclaim or
similar rights with respect to such participation as fully as if such Lender
were a direct holder of Loans (or Letters of Credit) in the amount of such
participation. Nothing contained herein shall require any Lender to exercise any
such right or shall affect the right of any Lender to exercise, and retain the
benefits of exercising, any such right with respect to any other indebtedness or
obligation of each Borrower. If under any applicable bankruptcy, insolvency or
other similar law, any Lender receives a secured claim in lieu of a set-off to
which this Section 4.05 applies, such Lender shall, to the extent practicable,
exercise its rights in respect of such secured claim in a manner consistent with
the rights of the Applicable Lenders entitled under this Section 4.05 to share
the benefits of any recovery on such secured claim.
          (c) Notwithstanding anything to the contrary contained in this
Agreement, the Lenders hereby agree that they shall not set off any funds in any
lock boxes whatsoever in connection with this Agreement, except for such lock
boxes which may be established in connection with this Agreement.

--------------------------------------------------------------------------------

 

     Section 4.06 Taxes.
          (a) Payments Free and Clear. Any and all payments by each Borrower
hereunder shall be made, in accordance with Section 4.01, free and clear of and
without deduction for any and all present or future taxes, levies, imposts,
deductions, charges or withholdings, and all liabilities with respect thereto,
excluding, in the case of each Lender, the Issuing Bank and the Administrative
Agents (each a “Recipient”), taxes imposed on (or measured by) its net income
and franchise, margin or similar taxes imposed on it, by (i) any jurisdiction
(or political subdivision thereof) of which such Recipient is a citizen or
resident or in which such Lender has an Applicable Lending Office, (ii) the
jurisdiction (or any political subdivision thereof) in which such Recipient is
organized, or (iii) any jurisdiction (or political subdivision thereof) in which
such Recipient is presently doing business which taxes are imposed solely as a
result of doing business in such jurisdiction (all such non-excluded taxes,
levies, imposts, deductions, charges, withholdings and liabilities being
hereinafter referred to as “Taxes”). For the avoidance of doubt, any withholding
taxes imposed by the United States of America on payments made by any Borrower
hereunder shall be included within the definition of “Taxes.” If any Borrower
shall be required by law to deduct any Taxes or Other Taxes from or in respect
of any sum payable hereunder to a Recipient, (A) except as provided in
Section 13.06(b), the sum payable shall be increased by the amount necessary so
that after making all required deductions (including deductions applicable to
additional sums payable under this Section 4.06) such Recipient shall receive an
amount equal to the sum it would have received had no such deductions been made,
(B) such Borrower shall make such deductions and (C) such Borrower shall pay the
full amount deducted to the relevant taxing authority or other Governmental
Authority in accordance with applicable law.
          (b) Other Taxes. In addition, to the fullest extent permitted by
applicable law, each Borrower agrees to pay any present or future stamp or
documentary taxes or any other excise or property taxes, charges or similar
levies that arise from any payment made hereunder or from the execution,
delivery or registration of, or otherwise with respect to, this Agreement, any
Assignment or any Security Instrument (hereinafter referred to as “Other
Taxes”).
          (c) Indemnification. To the fullest extent permitted by applicable
law, the Borrowers will indemnify each Lender and the Issuing Bank and the
Administrative Agents for the full amount of Taxes and Other Taxes (including,
but not limited to, any Taxes or Other Taxes imposed by any Governmental
Authority on amounts payable under this Section 4.06) paid by such Lender, the
Issuing Bank or the Administrative Agents (on their behalf or on behalf of any
Lender), as the case may be, and any liability (including penalties, interest
and expenses) arising therefrom or with respect thereto, whether or not such
Taxes or Other Taxes were correctly or legally asserted unless the payment of
such Taxes was not correctly or legally asserted and such Lender’s payment of
such Taxes or Other Taxes was the result of its or its officers’, employees’,
agents’ or representatives’ gross negligence or willful misconduct. Any payment
pursuant to such indemnification shall be made within thirty (30) days after the
date any Lender, the Issuing Bank or the Administrative Agents, as the case may
be, make written demand therefor. If any Lender, Issuing Bank, the US
Administrative Agent or the Canadian Administrative Agent receives a refund or
credit in respect of any Taxes or Other Taxes for which such Lender, Issuing
Bank, the US Administrative Agent or the Canadian Administrative Agent has
received payment from the Applicable Borrower it shall promptly notify the

-59-

--------------------------------------------------------------------------------

 

Applicable Borrower of such refund or credit and shall, if no default has
occurred and is continuing, within thirty (30) days after receipt of a request
by the Applicable Borrower (or promptly upon receipt, if the Applicable Borrower
has requested application for such refund or credit pursuant hereto), pay an
amount equal to such refund or credit to the Applicable Borrower without
interest (but with any interest so refunded or credited), provided that the
Applicable Borrower, upon the request of such Lender, Issuing Bank, the US
Administrative Agent or the Canadian Administrative Agent, agrees to return such
refund or credit (plus penalties, interest or other charges) to such Lender,
Issuing Bank, the US Administrative Agent or the Canadian Administrative Agent
in the event such Lender, Issuing Bank or Administrative Agent is required to
repay such refund or credit.
          (d) Lender Representations.
     (i) Each US Lender represents that it is either (A) a “United States
person” (as such term is defined in Code Section 7701(a)(30)) or (B) is entitled
to complete exemption from United States withholding tax imposed on or with
respect to any payments, including fees, to be made to it pursuant to this
Agreement (1) under an applicable provision of a tax convention to which the
United States of America is a party, (2) because such US Lender is not described
in Code Sections 871(h)(3) or 881(c)(3), or (3) because it is acting through a
branch, agency or office in the United States of America and any payment to be
received by it hereunder is effectively connected with a trade or business in
the United States of America. Each US Lender that is not a “United States
person” (as such term is defined in Code Section 7701(a)(30)) agrees to provide
to the US Borrowers and the US Administrative Agent on the Closing Date, or on
the date of its delivery of the Assignment pursuant to which it becomes a US
Tranche Revolving Lender or Term Loan Lender, and at such other times as
required by United States law or as a US Borrower or the US Administrative Agent
shall reasonably request, two accurate and complete original signed copies of
IRS Form W-8BEN, W-8ECI or W-8IMY (or successor or other applicable forms
prescribed by the IRS) certifying to such US Lender’s entitlement to a complete
exemption from United States withholding Tax on interest payments to be made
under this Agreement; provided, however, that no such US Lender shall be
required to deliver an IRS Form W-8BEN, W-8ECI, or W-8IMY to the extent that the
delivery of such form is not authorized by law due to a change in a Governmental
Requirement occurring subsequent to the date on which a form was originally
required to be provided; provided further, however, that in the event that a US
Lender provides the US Borrowers or the US Administrative Agent with an IRS Form
W-8-IMY (or substitute form) indicating that it is a “flow through” entity, as
defined in Treasury Regulations promulgated under Code Section 1441, or
otherwise, not a beneficial owner of interest payments under this Agreement,
such US Lender agrees, on or prior to the Closing Date, or the date of
Assignment to such US Lender, as applicable, to take any actions necessary, and
to deliver to the US Borrowers and the US Administrative Agent all forms
necessary, to establish such US Lender’s entitlement to a complete exemption
from United States withholding Tax on payments of interest to be made under this
Agreement, including causing its partners, members, beneficiaries, beneficial
owners, and their beneficial owners, if any, to take any actions and deliver any
forms necessary to establish such exemption. Notwithstanding the foregoing, a
withholding foreign partnership, withholding foreign trust, and qualified
intermediary

-60-

--------------------------------------------------------------------------------

 

shall only provide such information as is required by Treasury Regulations
promulgated under Code Section 1441. For purposes of this Agreement, the term
“forms” shall include any attachments to IRS Forms W-8IMY required to be filed
by the US Lender.
     (ii) Each US Lender that is a “United States person” (as such term is
defined in Code Section 7701(a)(30)) shall provide two properly completed and
duly executed copies of IRS Form W-9, or any successor or other applicable form.
Each such US Lender shall deliver to the US Borrower and the US Administrative
Agent (provided that such US Lender remains lawfully able to do so), two further
duly executed copies of such form or statement, properly completed in all
material respects, at or before the time any such form or statement expires or
becomes obsolete, or otherwise as reasonably requested by the US Borrowers. Each
such US Lender shall promptly notify the US Borrowers at any time it determines
that it is no longer in a position to provide any previously delivered form or
statement to the US Borrowers and the US Administrative Agent (or any other form
or statement adopted by U.S. taxing authorities for such purpose).
     (iii) Each US Lender also agrees to deliver to the US Borrowers and the US
Administrative Agent such other or supplemental forms as may at any time be
required as a result of changes in applicable law or regulation in order to
confirm or maintain in effect its entitlement to exemption from United States
withholding Tax on any payments hereunder, provided that the circumstances of
such US Lender at the relevant time and applicable laws permit it to do so. If a
US Lender determines, as a result of any change in either (i) a Governmental
Requirement or (ii) its circumstances, that it is unable to submit any form or
certificate that it is obligated to submit pursuant to this Section 4.06, or
that it is required to withdraw or cancel any such form or certificate
previously submitted, it shall promptly notify the US Borrowers and the US
Administrative Agent of such fact. Except as provided in Section 4.06(d)(iv),
each US Lender agrees to indemnify and hold harmless the US Borrowers or the US
Administrative Agent, as applicable, from any United States Taxes, penalties,
interest and other expenses, costs and losses incurred or payable by (A) the US
Borrowers or the US Administrative Agent as a result of such US Lender’s failure
to submit any form or certificate that it is required to provide pursuant to
this Section 4.06 or (B) the US Borrowers or the US Administrative Agent as a
result of their reliance on any such form or certificate which such US Lender
has provided to them pursuant to this Section 4.06.
     (iv) For any period with respect to which a US Lender has failed to provide
the US Borrowers with the form required pursuant to this Section 4.06, if any
(other than if such failure is due to a change in a Governmental Requirement
occurring subsequent to the date on which a form originally was required to be
provided, in which case, such US Lender shall be entitled to indemnification
under this Section 4.06 (including, without limitation, the right to receive
additional amounts pursuant to Section 4.06(a)(A)) and shall not be required to
indemnify the US Borrowers or the US Administrative Agent pursuant to
Section 4.06(d)(iii)(A)), such US Lender shall not be entitled to
indemnification under Section 4.06 with respect to Taxes imposed by the United
States which Taxes would not have been imposed but for such failure to provide
such forms; provided, however, that if a US Lender, which is otherwise exempt
from or subject to a reduced rate of withholding Tax, becomes subject to Taxes
because of its failure to

-61-

--------------------------------------------------------------------------------

 

deliver a form required hereunder, the US Borrowers shall take such steps as
such US Lender shall reasonably request to assist such US Lender to recover such
Taxes.
     (v) Any US Lender claiming any additional amounts payable pursuant to this
Section 4.06 shall use reasonable efforts (consistent with legal and regulatory
restrictions) to file any certificate or document requested by the US Borrowers
or the US Administrative Agent or to change the jurisdiction of its Applicable
Lending Office or to contest any Tax imposed if the making of such a filing or
change or contesting such Tax would avoid the need for or reduce the amount of
any such additional amounts that may thereafter accrue and would not, in the
sole determination of such US Lender, be otherwise disadvantageous to such US
Lender.
     (vi) Each Canadian Tranche Revolving Lender represents that it is
(A) either (x) not a non-resident of Canada for purposes of the Income Tax Act
(Canada) or (y) a deemed resident of Canada for purposes of Part XIII of the
Income Tax Act (Canada) and (B) an Affiliate of a US Tranche Revolving Lender.
Each Canadian Tranche Revolving Lender agrees to indemnify and hold harmless the
Canadian Borrowers or the Canadian Administrative Agent, as applicable, from any
Canadian taxes, penalties, interest and other expenses, costs and losses
incurred or payable by the Canadian Borrowers or the Canadian Administrative
Agent as a result of its reliance on any representation in this
Section 4.06(d)(vi) (other than if such misrepresentation is due to a change in
a Governmental Requirement occurring subsequent to the date on which such
representation was made, in which case, such Canadian Tranche Revolving Lender
shall be entitled to indemnification under this Section 4.06 (including, without
limitation, the right to receive additional amounts pursuant to
Section 4.06(a)(A)) and shall not be required to indemnify the Canadian
Borrowers or the Canadian Administrative Agent pursuant to Section 4.06(d)(vi)).
ARTICLE V
Capital Adequacy
     Section 5.01 Additional Costs.
          (a) Regulations, etc. The Borrowers shall pay directly to each
Applicable Lender from time to time such amounts as such Lender may determine to
be necessary to compensate such Lender for any costs which it determines are
attributable to its making or maintaining of any US Dollar LIBOR Loans,
accepting and purchasing Bankers’ Acceptances, making or maintaining BA
Equivalent Loans or issuing or participating in Letters of Credit hereunder or
its obligation to make any US Dollar LIBOR Loans, purchase any Bankers’
Acceptances, make any BA Equivalent Loans or issue or participate in any Letters
of Credit hereunder, or any reduction in any amount receivable by such Lender
hereunder in respect of any of such US Dollar LIBOR Loans, Bankers’ Acceptances,
BA Equivalent Loans, Letters of Credit or such obligation, resulting from any
Regulatory Change which: (i) changes the basis of taxation of any amounts
payable to such Lender under this Agreement or any Note or BA Equivalent Note in
respect of any of such US Dollar LIBOR Loans, Bankers’ Acceptances, BA
Equivalent Loans or Letters of Credit (other than taxes imposed on the overall
net income of such Lender or of its Applicable Lending Office for any of such US
Dollar LIBOR Loans by the jurisdiction in which such Lender has its principal
office or Applicable Lending Office); or

-62-

--------------------------------------------------------------------------------

 

(ii) imposes or modifies any reserve, special deposit, minimum capital, capital
ratio or similar requirements relating to any extensions of credit or other
assets of, or any deposits with or other liabilities of such Lender, or the US
Tranche Commitment, Canadian Allocated Commitment, Term Commitment or Loans of
such Lender or the London interbank market; or (iii) imposes any other condition
affecting this Agreement or any Note or BA Equivalent Note (or any of such
extensions of credit or liabilities) or such Lender’s US Tranche Commitment,
Canadian Allocated Commitment, Term Commitment or Loans. Each Lender will notify
the US Administrative Agent and the Applicable Borrower of any event occurring
after the Closing Date which will entitle such Lender to compensation pursuant
to this Section 5.01(a) as promptly as practicable after it obtains knowledge
thereof and determines to request such compensation, and will designate a
different Applicable Lending Office for the Loans of such Lender affected by
such event if such designation will avoid the need for, or reduce the amount of,
such compensation and will not, in the sole opinion of such Lender, be
disadvantageous to such Lender, provided that such Lender shall have no
obligation to so designate an Applicable Lending Office located in the United
States. If any Lender requests compensation from any Borrower under this
Section 5.01(a), such Borrower may, by notice to such Lender, suspend the
obligation of such Lender to make additional Loans of the Type with respect to
which such compensation is requested until the Regulatory Change giving rise to
such request ceases to be in effect (in which case the provisions of
Section 5.04 shall be applicable).
          (b) Regulatory Change. Without limiting the effect of the provisions
of Section 5.01(a), in the event that at any time (by reason of any Regulatory
Change or any other circumstances arising after the Closing Date affecting
(i) any Lender, (ii) the London interbank market or (iii) such Lender’s position
in such market), the US Dollar LIBO Rate, as determined in good faith by such
Lender, will not adequately and fairly reflect the cost to such Lender of
funding its US Dollar LIBOR Loans, then, if such Lender so elects, by notice to
the US Borrowers and the US Administrative Agent, the obligation of such Lender
to make additional US Dollar LIBOR Loans shall be suspended until such
Regulatory Change or other circumstances ceases to be in effect (in which case
the provisions of Section 5.04 shall be applicable).
          (c) Capital Adequacy. Without limiting the effect of the foregoing
provisions of this Section 5.01 (but without duplication), the Borrowers shall
pay directly to any Applicable Lender from time to time on request such amounts
as such Lender may reasonably determine to be necessary to compensate such
Lender or its parent or holding company for any costs which it determines are
attributable to the maintenance by such Lender or its parent or holding company
(or any Applicable Lending Office), pursuant to any Governmental Requirement
following any Regulatory Change, of capital in respect of its US Tranche
Commitments, its Canadian Allocated Commitments, its Term Commitments, its Note,
its Loans or any interest held by it in any Letter of Credit, such compensation
to include, without limitation, an amount equal to any reduction of the rate of
return on assets or equity of such Lender or its parent or holding company (or
any Applicable Lending Office) to a level below that which such Lender or its
parent or holding company (or any Applicable Lending Office) could have achieved
but for such Governmental Requirement. Such Lender will notify the Applicable
Borrower that it is entitled to compensation pursuant to this Section 5.01(c) as
promptly as practicable after it determines to request such compensation.

-63-

--------------------------------------------------------------------------------

 

          (d) Compensation Procedure. Any Lender notifying the Applicable
Borrower of the incurrence of additional costs under this Section 5.01 shall in
such notice to such Borrower and the US Administrative Agent set forth in
reasonable detail the basis and amount of its request for compensation.
Determinations and allocations by each Lender for purposes of this Section 5.01
of the effect of any Regulatory Change pursuant to Section 5.01(a) or (b), or of
the effect of capital maintained pursuant to Section 5.01(c), on its costs or
rate of return of maintaining Loans or its obligation to make Loans or issue
Letters of Credit, or on amounts receivable by it in respect of Loans or Letters
of Credit, and of the amounts required to compensate such Lender under this
Section 5.01, shall be conclusive and binding for all purposes, provided that
such determinations and allocations are made on a reasonable basis. Any request
for additional compensation under this Section 5.01 shall be paid by the
Applicable Borrower within thirty (30) days of the receipt by such Borrower of
the notice described in this Section 5.01(d).
     Section 5.02 Limitation on US Dollar LIBOR Loans. Anything herein to the
contrary notwithstanding, if, on or prior to the determination of any US Dollar
LIBO Rate for any Interest Period:
          (a) the US Administrative Agent determines (which determination shall
be conclusive, absent manifest error) that quotations of interest rates for the
relevant deposits referred to in the applicable definition of “US Dollar LIBO
Rate” in Section 1.02 are not being provided in the relevant amounts or for the
relevant maturities for purposes of determining rates of interest for US Dollar
LIBOR Loans as provided herein; or
          (b) the US Administrative Agent determines (which determination shall
be conclusive, absent manifest error) that the relevant rates of interest
referred to in the applicable definition of “US Dollar LIBO Rate” in
Section 1.02 upon the basis of which the rate of interest for US Dollar LIBOR
Loans for such Interest Period is to be determined are not sufficient to
adequately cover the cost to the Lenders of making or maintaining US Dollar
LIBOR Loans;
then the US Administrative Agent shall give the US Borrowers prompt notice
thereof, and so long as such condition remains in effect, the Lenders shall be
under no obligation to make additional US Dollar LIBOR Loans.
     Section 5.03 Illegality. Notwithstanding any other provision of this
Agreement, in the event that it becomes unlawful for any Lender or its
Applicable Lending Office to honor its obligation to make or maintain US Dollar
LIBOR Loans hereunder, then such Lender shall promptly notify the US Borrowers
thereof and such Lender’s obligation to make US Dollar LIBOR Loans shall be
suspended until such time as such Lender may again make and maintain US Dollar
LIBOR Loans (in which case the provisions of Section 5.04 shall be applicable).
     Section 5.04 US Dollar Base Rate Loans Pursuant to Sections 5.01, 5.02 and
5.03. If the obligation of any Lender to make US Dollar LIBOR Loans shall be
suspended pursuant to Sections 5.01, 5.02 or 5.03 (“Affected Loans”), all
Affected Loans which would otherwise be made by such Lender shall be made
instead as US Dollar Base Rate Loans (and, if an event referred to in
Section 5.01(b) or Section 5.03 has occurred and such Lender so requests by
notice to the US Borrowers, all Affected Loans of such Lender then outstanding
shall be automatically converted into US Dollar Base Rate Loans on the date
specified by the Lender in such notice)

-64-

--------------------------------------------------------------------------------

 

and, to the extent that Affected Loans are so made as (or converted into) US
Dollar Base Rate Loans, all payments of principal which would otherwise be
applied to such Lender’s Affected Loans shall be applied instead to its
respective US Dollar Base Rate Loans.
     Section 5.05 Compensation.
          (a) The Borrowers shall pay to each Applicable Lender within thirty
(30) days of receipt of written request of such Lender (which request shall set
forth, in reasonable detail, the basis for requesting such amounts and which
shall be conclusive and binding for all purposes provided that such
determinations are made on a reasonable basis), such amount or amounts as shall
compensate it for any loss, cost, expense or liability which such Lender
determines are attributable to:
     (i) any payment, prepayment or conversion of a US Dollar LIBOR Loan
properly made by such Lender or any Borrower for any reason (including, without
limitation, the acceleration of the Loans pursuant to Section 11.02) on a date
other than the last day of the Interest Period for such Loan; or
     (ii) any failure by a Borrower for any reason (including but not limited
to, the failure of any of the conditions precedent specified in ARTICLE VI to be
satisfied) to borrow, continue or convert a US Dollar LIBOR Loan from such
Lender on the date for such Borrowing, continuation or conversion specified in
the relevant notice given pursuant to Section 2.02(c).
Without limiting the effect of the preceding sentence, such compensation shall
include an amount equal to the excess, if any, of (A) the amount of interest
which would have accrued on the Principal Amount so paid, prepaid or converted
or not borrowed for the period from the date of such payment, prepayment or
conversion or failure to borrow to the last day of the Interest Period for such
Loan (or, in the case of a failure to borrow, the Interest Period for such Loan
which would have commenced on the date specified for such Borrowing) at the
applicable rate of interest for such Loan provided for herein over (B) the
interest component of the amount such Lender would have bid in the London
interbank market for US Dollar deposits of leading banks in amounts comparable
to such Principal Amount and with maturities comparable to such period (as
reasonably determined by such Lender).
          (b) In the event of (i) the payment of any Principal Amount of any BA
Equivalent Loan or Bankers’ Acceptance other than on the applicable BA Maturity
Date (including as a result of an Event of Default), (ii) the continuation of
any BA Equivalent Loan other than on the applicable BA Maturity Date, (iii) the
failure to borrow any such Bankers’ Acceptance or borrow or continue BA
Equivalent Loan on the date specified in any notice delivered pursuant hereto,
(iv) the assignment of any BA Equivalent Loan or Bankers’ Acceptance other than
on the applicable BA Maturity Date as a result of a request by the Canadian
Borrowers, then, in any such event, the Canadian Borrowers shall compensate each
Applicable Lender for the loss, cost and expense attributable to such event. A
certificate of any such Lender setting forth any amount or amounts that such
Lender is entitled to receive pursuant to this Section 5.05(b) shall be
delivered to the Canadian Borrowers and the Administrative Agents and shall be
conclusive absent manifest error. The Canadian Borrowers shall pay such Lender
the amount shown as due on any such certificate within thirty (30) days after
receipt

-65-

--------------------------------------------------------------------------------

 

thereof. Notwithstanding anything to the contrary contained herein, nothing in
this Section 5.05(b) shall be construed as giving rise to any right of the
Canadian Borrowers to prepay any Bankers’ Acceptance or BA Equivalent Loan.
     Section 5.06 Replacement Lenders.
          (a) If any Lender has notified the Borrowers and the US Administrative
Agent of its incurring additional costs under Section 5.01 or has required the
Borrowers to make payments for Taxes under Section 4.06, then the Borrowers may,
unless such Lender has notified the Borrowers and the US Administrative Agent
that the circumstances giving rise to such notice no longer apply, terminate, in
whole but not in part, the US Tranche Commitment, Canadian Allocated Commitment
and Term Loans, if any, of any Lender (other than the Administrative Agents)
(the “Terminated Lender”) at any time upon five (5) Business Days’ prior written
notice to the Terminated Lender and the US Administrative Agent (such notice
referred to herein as a “Notice of Termination”).
          (b) In order to effect the termination of the US Tranche Commitment,
the Canadian Allocated Commitment and the Term Loans, as applicable, of the
Terminated Lender, the Borrowers shall: (i) obtain an agreement with one or more
Lenders to increase their US Tranche Commitment or US Tranche Commitments, their
Canadian Allocated Commitment or Canadian Allocated Commitments and their Term
Loans, as applicable and/or (ii) request any one or more other banking
institutions to become parties to this Agreement in place and instead of such
Terminated Lender and agree to accept such commitment or commitments; provided,
however, that such one or more other banking institutions are reasonably
acceptable to the Administrative Agents and become parties by executing an
Assignment and that any replacement of a terminated Canadian Tranche Revolving
Lender shall satisfy the Canadian residency requirements of a Canadian Tranche
Revolving Lender (the Lenders or other banking institutions that agree to accept
in whole or in part the US Tranche Commitment, Canadian Allocated Commitment and
Term Loans, if any, of the Terminated Lender being referred to herein as the
“Replacement Lenders”), such that the aggregate increased and/or accepted
commitments and the Term Loans of the Replacement Lenders under clauses (i) and
(ii) above equal the US Tranche Commitment, the Canadian Allocated Commitment
and the Term Loans, if any, of the Terminated Lender.
          (c) The Notice of Termination shall include the name of the Terminated
Lender, the date the termination will occur (the “Lender Termination Date”), and
the Replacement Lender or Replacement Lenders to which the Terminated Lender
will assign its US Tranche Commitment, Canadian Allocated Commitment and Term
Loans, if any, and, if there will be more than one Replacement Lender, the
portion of the Terminated Lender’s US Tranche Commitment, Canadian Allocated
Commitment and Term Loans, if any, to be assigned to each Replacement Lender.
          (d) On the Lender Termination Date (i) the Terminated Lender shall by
execution and delivery of an Assignment assign its US Tranche Commitment,
Canadian Allocated Commitment and Term Loans, if any, to the Replacement Lender
or Replacement Lenders (pro rata, if there is more than one Replacement Lender,
in proportion to the portion of the Terminated Lender’s US Tranche Commitment,
Canadian Allocated Commitment and Term Loans, if any, to be assigned to each
Replacement Lender) indicated in the Notice of

-66-

--------------------------------------------------------------------------------

 

Termination and shall assign to the Replacement Lender or Replacement Lenders
each of its Loans (if any) then outstanding and participation interests in
Letters of Credit (if any) then outstanding pro rata as aforesaid, (ii) the
Terminated Lender shall endorse its Note(s), Bankers’ Acceptances and BA
Equivalent Notes, payable without recourse, representation or warranty to the
order of the Replacement Lender or Replacement Lenders (pro rata as aforesaid),
(iii) the Replacement Lender or Replacement Lenders shall purchase the Note(s),
Bankers’ Acceptances and BA Equivalent Notes held by the Terminated Lender (pro
rata as aforesaid) at a price equal to the unpaid Principal Amount thereof plus
interest and facility and other fees accrued and unpaid to the Lender
Termination Date, and (iv) the Replacement Lender or Replacement Lenders will
thereupon (pro rata as aforesaid) succeed to and be substituted in all respects
for the Terminated Lender with like effect as if becoming a Lender pursuant to
the terms of Section 13.06(b), and the Terminated Lender will have the rights
and benefits of an assignor under Section 13.06(b). To the extent not in
conflict, the terms of Section 13.06(b) shall supplement the provisions of this
Section 5.06(d). For each Assignment made under this Section 5.06, the
Replacement Lender shall pay to the Applicable Administrative Agent the
processing fee provided for in Section 13.06(b). The Borrowers will be
responsible for the payment of any breakage costs incurred in connection with
the sale of Loans by Terminated Lenders to Replacement Lenders, as if such Loans
had been prepaid and breakage costs had accrued thereto in accordance with
Section 5.05.

than $100,000 the fair market value of the assets of such Plan, and the present
value of all accumulated benefit obligations of all underfunded Plans (based on
the assumptions used for purposes of Statement of Financial Accounting Standards

the aggregate. The charges, accruals and reserves on the books of it and its
Domestic Subsidiaries in respect of taxes and other governmental charges are, in
the opinion of the US Borrowers, adequate. No tax lien has been filed and, to
the knowledge of the US Borrowers, no claim is being asserted with respect to

Subsidiaries which has a Material Adverse Effect and which

in Canadian Dollars (other than, for the avoidance of doubt, obligations in
respect of undrawn Offshore

-92-

--------------------------------------------------------------------------------

 

Currency Letters of Credit) shall, automatically and with no further act
required, be converted to obligations of the same Borrower denominated in US
Dollars. Such conversion shall be effected based upon the exchange rate
described in the definition of “US Dollar Equivalent Amount” on the CAM Exchange
Date. On and after any such conversion, all amounts accruing and owed to any
Lender in respect of the Indebtedness owed to it under the Loan Documents shall
accrue and be payable in US Dollars at the rates otherwise applicable hereunder.
Subject to Section 11.02(d), as a result of the CAM Exchange, upon and after the
CAM Exchange Date, each payment or proceeds received by the Applicable
Administrative Agent pursuant to or as a result of the execution of any remedy
under any Loan Document in respect of the Indebtedness of the Borrowers under
the Loan Documents shall be distributed to the Lenders pro rata in accordance
with their respective CAM Percentages. Any direct payment received by a Lender
upon or after the CAM Exchange Date, including by way of set-off, in respect of
the Indebtedness under the Loan Documents shall be paid over to the US
Administrative Agent for distribution to the Lenders in accordance herewith.
          (d) Hedging Agreements between any US Borrower and any of their
Subsidiaries and the Administrative Agents or a Lender and/or any Lender
Affiliate are secured by the Security Instruments pari passu with all other
Indebtedness. As such, proceeds from the Security Instruments shall be shared
pro rata on all Indebtedness. All proceeds received after the later to occur of
the Term Loan Maturity Date or the Revolving Maturity Date, whether by
acceleration or otherwise, shall be applied first to reimbursement of expenses
provided for in the Security Instruments; next to be shared pro rata between the
Hedging Agreements (which form part of the Indebtedness) on the one hand and all
other Indebtedness pursuant to this Agreement and the other Loan Documents on
the other hand. Thereafter, all such proceeds applicable to the Loans and other
obligations under this Agreement and the other Loan Documents shall be applied,
first to reimbursement of expenses and indemnities provided for in this
Agreement and the other Loan Documents; second to accrued interest on the Loans;
third to fees; fourth pro rata to principal outstanding on the Loans and other
Indebtedness and to serve as cash collateral to be held by the US Administrative
Agent to secure the LC Exposure and by the Canadian Administrative Agent to
secure outstanding BA Exposure; and any excess shall be paid to the US Borrowers
or as otherwise required by any Governmental Requirement.
          (e) Acceleration and termination of all Hedging Agreements involving
the Administrative Agents or Lenders or the Lender Affiliates shall be governed
by the terms of the Hedging Agreements.
     Section 11.03 Letters of Credit.
          (a) In the event that on the CAM Exchange Date any LC Exposure shall
be outstanding, each US Tranche Revolving Lender shall promptly pay over to the
US Administrative Agent, in immediately available funds, an amount in US Dollars
equal to such US Tranche Revolving Lender’s US Tranche Percentage of such LC
Exposure (or, in the case of any Offshore Currency Letter of Credit, the US
Dollar Equivalent of such LC Exposure) together with interest thereon from the
CAM Exchange Date to the date on which such amount shall be paid to the US
Administrative Agent at the rate that would be applicable at the time to a US
Dollar Base Rate Loan in a Principal Amount equal to such US Lender’s US Tranche
Percentage of the LC Exposure. The US Administrative Agent shall establish a
separate account (each, a “Reserve Account”) or accounts for each Lender for the
amounts received with respect to each

-93-

--------------------------------------------------------------------------------

 

such Letter of Credit pursuant to the preceding sentence. The US Administrative
Agent shall have sole dominion and control over each Reserve Account, and the
amounts deposited in each Reserve Account shall be held in such Reserve Account
until withdrawn as provided in paragraph (b), (c), (d) or (e) below. The US
Administrative Agent shall maintain records enabling it to determine the amounts
paid over to it and deposited in the Reserve Accounts in respect of each Letter
of Credit and the amounts on deposit in respect of each letter of Credit
attributable to each Lender’s CAM Percentage. The amounts held in each Lender’s
Reserve Account shall be held as a reserve against the LC Exposure, shall be the
property of such Lender, shall not constitute Loans to or give rise to any claim
of or against any Borrower and shall not give rise to any obligation on the part
of the Borrowers to pay interest to such Lender, it being agreed that the
reimbursement obligations in respect of Letters of Credit shall arise only at
such times as drawings are made thereunder, as provided in Section 2.10.
          (b) In the event that after the CAM Exchange Date any drawing shall be
made in respect of a Letter of Credit, the US Administrative Agent shall, at the
request of the applicable Issuing Bank, withdraw from the Reserve Account of
each Lender any amounts, up to the amount of such Lender’s CAM Percentage of
such drawing or payment, deposited in respect of such Letter of Credit and
remaining on deposit and deliver such amounts to such Issuing Bank in
satisfaction of the reimbursement obligations of the US Tranche Revolving
Lenders under Section 2.10(c). In the event that any US Tranche Revolving Lender
shall default on its obligation to pay over any amount to the US Administrative
Agent as provided in this Section 11.03, the applicable Issuing Bank shall have
a claim against such US Tranche Revolving Lender to the same extent as if such
US Tranche Revolving Lender had defaulted on its obligations under
Section 2.10(c), but shall have no claim against any other Lender in respect of
such defaulted amount, notwithstanding the exchange of interests in the US
Borrowers’ reimbursement obligations pursuant to Section 11.02(c). Each other
Lender shall have a claim against such defaulting US Tranche Revolving Lender
for any damages sustained by it as a result of such default, including, in the
event that such Letter of Credit shall expire undrawn, its CAM Percentage of the
defaulted amount.
          (c) In the event that after the CAM Exchange Date any Letter of Credit
shall expire undrawn, the US Administrative Agent shall withdraw from the
Reserve Account of each Lender the amount remaining on deposit therein in
respect of such Letter of Credit, and distribute such amount to such Lender.
          (d) With the prior written approval of the US Administrative Agent
(not to be unreasonably withheld), any Lender may withdraw the amount held in
its Reserve Account in respect of the undrawn amount of any Letter of Credit.
Any Lender making such a withdrawal shall be unconditionally obligated, in the
event there shall subsequently be a drawing under such Letter of Credit, to pay
to the US Administrative Agent, for the account of the Issuing Bank, on demand,
its CAM Percentage of such drawing or payment.
          (e) Pending the withdrawal by any Lender of any amounts from its
Reserve Account as contemplated by the above paragraphs, the US Administrative
Agent will, at the direction of such Lender and subject to such rules as the US
Administrative Agent may prescribe for the avoidance of inconvenience, invest
such amounts in Investments described in Sections 10.03(c), (d), (e) or (f).
Each Lender that has not withdrawn its amounts in its Reserve Account as
provided in paragraph (d) above shall have the right, at intervals reasonably
specified by the US

-94-

--------------------------------------------------------------------------------

 

Administrative Agent, to withdraw the earnings on investments so made by the US
Administrative Agent with amounts in its Reserve Account and to retain such
earnings for its own account.

powers hereunder as any other Lender and may exercise the same as though it were
not acting as the Applicable Administrative Agent, and the term “Lender” or
“Lenders” shall, unless the context otherwise indicates, include the Applicable
Administrative Agent in its individual capacity. Each Applicable Administrative
Agent (and any successor acting as such Applicable Administrative Agent) and its
Affiliates may (without having to account therefor to any Lender) accept
deposits from, lend money to and generally engage in any kind of banking, trust

it were not acting as the Applicable Administrative Agent, and each Applicable
Administrative Agent and its Affiliates may accept fees and other consideration

Administrative Agents and the Issuing Bank ratably in accordance with their
Percentage Shares prior to the CAM Exchange Date and with their CAM Percentage
on or after the CAM Exchange Date for the Indemnity Matters as described in

of any kind and nature whatsoever which may be imposed on, incurred by or

foregoing to the extent they arise from the gross negligence or willful
misconduct of the Administrative Agents or the Issuing Bank, as the case may be;

Issuing Banks (with respect to the Revolving Credit Facility only), (D) with
respect to the Revolving Credit Facility only, the US Borrowers, provided that
no such consent shall be required for an assignment to an assignee that is an
Affiliate (as defined in clause (a) of the definition of “Affiliate”) of such
Term Loan Lender, a Related Fund or a Term Loan Lender immediately prior to
giving effect to such assignment, or if an Event of Default has occurred and is
continuing, any other assignee and (E) with respect to the Term Loan Credit
Facility only, the US Borrowers, provided that no such consent shall be required
for an assignment to an assignee that is an Affiliate (as defined in clause
(a) of the definition of “Affiliate”) of such Term Loan Lender, a Related Fund
or a Term Loan Lender immediately prior to giving effect to such assignment;
provided, however, that (i) any such assignment shall be in the amount of at
least $5,000,000 of a Tranche with respect to the Revolving Credit Facility and
at least $1,000,000 with respect to the Term Loan Facility or such lesser amount
to which such Borrower has consented, with Related Funds treated as one assignee
for purposes of determining compliance with such minimum assignment amount;
(ii) the assignee or assignor shall pay to the Applicable Administrative Agent a
processing and recordation fee of $3,500 for each assignment; provided

-102-

--------------------------------------------------------------------------------

 

that only $3,500 shall be paid for pro rata assignments by a Lender and its
Canadian Lender Affiliate and only one such fee shall be payable in connection
with simultaneous assignments to or by two or more Related Funds; (iii) if such
assignment is made at a time when no Event of Default has occurred and is
continuing, any assignee of the Canadian Tranche Revolving Lender shall satisfy
the Canadian residency requirements of a Canadian Tranche Revolving Lender;
(iv) any assignee shall not be a competitor of Holdings or any of its
Subsidiaries; and (v) notwithstanding anything to the contrary contained in this
Agreement, if such assignment is made at a time when an Event of Default has
occurred and is continuing, (y) the Borrowers shall have the right to withhold
all Taxes required by law to be withheld from payments made hereunder, and shall
pay such Taxes to the relevant taxing authority or other Governmental Authority
in accordance with applicable law and (z) any assignee of a Lender shall not be
subject to the provisions of Section 4.06(d) (other than subparagraph
(ii) thereof, if applicable), and shall not be entitled to receive any
additional amounts payable pursuant to Section 4.06(a)(A) or indemnification
payments for Taxes pursuant to Section 4.06(c). Any such assignment will become
effective upon the execution and delivery to the US Administrative Agent of the
Assignment and the consent, if required above, of the US Administrative Agent,
the Issuing Banks and, unless an Event of Default has occurred and is
continuing, the US Borrowers. Promptly after receipt of an executed Assignment,
the US Administrative Agent shall send to the Applicable Borrower a copy of such
executed Assignment. Upon receipt of such executed Assignment, such Borrower,
will, at its own expense, execute and deliver new Notes, Bankers’ Acceptances or
BA Equivalent Notes to the assignor and/or assignee, as appropriate, in
accordance with their respective interests as they appear. Upon the
effectiveness of any assignment pursuant to this Section 13.06(b), the assignee
will become a “Lender,” if not already a “Lender,” for all purposes of this
Agreement and the Security Instruments. The assignor shall be relieved of its
obligations hereunder to the extent of such assignment (and if the assigning
Lender no longer holds any rights or obligations under this Agreement, such
assigning Lender shall cease to be a “Lender” hereunder except that its rights
under Sections 4.06, 5.01, 5.05 and 13.03 shall not be affected). The US
Administrative Agent, acting as an agent of the Borrowers, shall maintain at one
of its offices a copy of each Assignment Agreement delivered to it and a
register for the recordation of the names and addresses of the Lenders, and the
Principal Amount of the Loans and LC Exposure owing to, each Lender pursuant to
the terms hereof from time to time (the “Register”). No assignment shall be
effective for purposes of this Agreement unless it has been recorded in the
Register.
          (c) Each Lender may transfer, grant or assign participations in all or
any part of such Lender’s interests hereunder pursuant to this Section 13.06(c)
to any Person that satisfies the requirements of Section 13.06(b)(iv) and either
Section 13.06(b)(iii) or (v)(z) as applicable, provided that: (i) such Lender
shall remain a “Lender” for all purposes of this Agreement and the transferee of
such participation shall not constitute a “Lender” hereunder; and (ii) no
participant under any such participation shall have rights to approve any
amendment to or waiver of any of the Loan Documents; provided that such
participation agreement may provide that such Lender will not, without the
consent of the participant, agree to any amendment, modification or waiver
described in clauses (a), (b) or (c) of the proviso to Section 13.04 that
affects such participant, and all amounts payable by the Applicable Borrower
hereunder shall be determined as if such Lender had not sold such participation,
provided that such participant shall be entitled to receive additional amounts
under ARTICLE V on the same basis as if it were a Lender and be indemnified
under Section 13.03 as if it were a Lender. In addition, each agreement creating
any

-103-

--------------------------------------------------------------------------------

 

participation must include an agreement by the participant to be bound by the
provisions of Section 13.15.
          (d) The Lenders may furnish any information concerning a Borrower in
the possession of the Lenders from time to time to assignees and participants
(including prospective assignees and participants); provided that, such Persons
agree to be bound by the provisions of Section 13.15.
          (e) Notwithstanding anything in this Section 13.06 to the contrary,
any Lender may at any time pledge or assign a security interest in all or any
portion of its rights under this Agreement to secure obligations of such Lender,
including, without limitation, any pledge or assignment to secure obligations to
a Federal Reserve Bank; provided that no such pledge or assignment of a security
interest shall release a Lender from any of its obligations hereunder or
substitute any such pledgee or assignee for such Lender as a party hereto.
          (f) Notwithstanding any other provisions of this Section 13.06, no
transfer or assignment of the interests or obligations of any Lender or any
grant of participations therein shall be permitted if such transfer, assignment
or grant would require any Borrower to file a registration statement with the
SEC or to qualify the Loans under the “Blue Sky” laws of any state.
     Section 13.07 Invalidity. In the event that any one or more of the
provisions contained in any of the Loan Documents or the Letters of Credit,
shall, for any reason, be held invalid, illegal or unenforceable in any respect,
such invalidity, illegality or unenforceability shall not affect any other
provision of the Notes, this Agreement or any Security Instrument.
     Section 13.08 Counterparts. This Agreement may be executed in any number of
counterparts, all of which taken together shall constitute one and the same
instrument and any of the parties hereto may execute this Agreement by signing
any such counterpart.
     Section 13.09 Reserved.
     Section 13.10 Survival. The obligations of the parties under Section 4.06,
ARTICLE V, and Sections 12.05 and 13.03 shall survive the repayment of the Loans
and the termination of the US Tranche Commitments, Canadian Allocated
Commitments and Term Commitments. To the extent that any payments on the
Indebtedness under the Loan Documents or proceeds of any Collateral are
subsequently invalidated, declared to be fraudulent or preferential, set aside
or required to be repaid to a trustee, debtor in possession, receiver or other
Person under any bankruptcy law, common law or equitable cause, then to such
extent, the Indebtedness under the Loan Documents so satisfied shall be revived
and continue as if such payment or proceeds had not been received and each
Applicable Administrative Agent’s and Lenders’ Liens, security interests,
rights, powers and remedies under this Agreement and each Security Instrument
shall continue in full force and effect. In such event, each Security Instrument
shall be automatically reinstated and the Applicable Borrower shall take such
action as may be reasonably requested by the Applicable Administrative Agent and
the Lenders to effect such reinstatement.
     Section 13.11 Reserved.

-104-

--------------------------------------------------------------------------------

 

     Section 13.12 No Oral Agreements. The Loan Documents embody the entire
agreement and understanding between the parties and supersede all other
agreements and understandings between such parties relating to the subject
matter hereof and thereof. The Loan Documents represent the final agreement
between the parties and may not be contradicted by evidence of prior,
contemporaneous or subsequent oral agreements of the parties. There are no
unwritten oral agreements between the parties.
     Section 13.13 Governing Law; Submission to Jurisdiction.
          (a) This Agreement and the Notes shall be governed by, and construed
in accordance with, the laws of the State of Texas except to the extent that
United States federal law permits any US Lender to charge interest at the rate
allowed by the laws of the state where such Lender is located or applicable
Canadian Law permits any Canadian Tranche Revolving Lender to charge interest at
the rate allowed by the laws of the jurisdiction where such Lender is located.
Ch. 346 of the Texas Finance Code (which regulates certain revolving credit loan
accounts and revolving tri-party accounts) shall not apply to this Agreement or
the Notes.
          (b) Any legal action or proceeding with respect to the Loan Documents
shall be brought in the courts of the State of Texas or of the United States of
America for the Southern District of Texas, and, by execution and delivery of
this Agreement, each Borrower hereby accepts for itself and (to the extent
permitted by law) in respect of its Property, generally and unconditionally, the
jurisdiction of the aforesaid courts. Each Borrower and Guarantor hereby
irrevocably waives any objection, including, without limitation, any objection
to the laying of venue or based on the grounds of forum non conveniens, which it
may now or hereafter have to the bringing of any such action or proceeding in
such respective jurisdictions. This submission to jurisdiction is non-exclusive
and does not preclude the Administrative Agents or any Lender from obtaining
jurisdiction over each Borrower and Guarantor in any court otherwise having
jurisdiction.
          (c) Each Borrower and Guarantor irrevocably consents to the service of
process of any of the aforementioned courts in any such action or proceeding by
the mailing of copies thereof by registered or certified mail, postage prepaid,
to such Borrower and Guarantor at its address located on the signature page
hereto or as updated from time to time, such service to become effective thirty
(30) days after such mailing.
          (d) Nothing herein shall affect the right of the Administrative Agents
or any Lender or any holder of a Note to serve process in any other manner
permitted by law or to commence legal proceedings or otherwise proceed against
the Borrowers or Guarantors in any other jurisdiction.
          (e) Each Borrower, each Guarantor and each Lender hereby (i)
irrevocably and unconditionally waive, to the fullest extent permitted by

-105-

--------------------------------------------------------------------------------

 

law, trial by jury in any legal action or proceeding relating to this Agreement
or any Security Instrument and for any counterclaim therein; (ii) irrevocably
waive, to the maximum extent not prohibited by law, any right it may have to
claim or recover in any such litigation any special, exemplary, punitive or
consequential damages, or damages other than, or in addition to, actual damages;
(iii) certify that no party hereto nor any representative of the Administrative
Agents or counsel for any party hereto has represented, expressly or otherwise,
or implied that such party would not, in the event of litigation, seek to
enforce the foregoing waivers, and (iv) acknowledge that it has been induced to
enter into this Agreement, the Security Instruments and the transactions
contemplated hereby and thereby by, among other things, the mutual waivers and
certifications contained in this Section 13.13.
     Section 13.14 Interest. It is the intention of the parties hereto that each
Lender shall conform strictly to usury laws applicable to it. Accordingly, if
the transactions contemplated hereby would be usurious as to any Lender under
laws applicable to it (including the laws of the United States of America and
the State of Texas or any other jurisdiction whose laws may be mandatorily
applicable to such Lender notwithstanding the other provisions of this
Agreement), then, in that event, notwithstanding anything to the contrary in any
of the Loan Documents or any agreement entered into in connection with or as
security for the Notes, the Bankers’ Acceptances and the BA Equivalent Notes, it
is agreed as follows: (a) the aggregate of all consideration which constitutes
interest under law applicable to any Lender that is contracted for, taken,
reserved, charged or received by such Lender under any of the Loan Documents or
agreements or otherwise in connection with the Notes shall under no
circumstances exceed the maximum amount allowed by such applicable law, and any
excess shall be canceled automatically and if theretofore paid shall be credited
by such Lender on the Principal Amount of the Indebtedness under the Loan
Documents (or, to the extent that the Principal Amount of the Indebtedness under
the Loan Documents shall have been or would thereby be paid in full, refunded by
such Lender to the Applicable Borrower); and (b) in the event that the maturity
of the Notes is accelerated by reason of an election of the holder thereof
resulting from any Event of Default under this Agreement or otherwise, or in the
event of any required or permitted prepayment, then such consideration that
constitutes interest under law applicable to any Lender may never include more
than the maximum amount allowed by such applicable law, and excess interest, if
any, provided for in this Agreement or otherwise shall be canceled automatically
by such Lender as of the date of such acceleration or prepayment and, if
theretofore paid, shall be credited by such Lender on the Principal Amount of
the Indebtedness under the Loan Documents (or, to the extent that the Principal
Amount of the Indebtedness under the Loan Documents shall have been or would
thereby be paid in full, refunded by such Lender to the Applicable Borrower).
All sums paid or agreed to be paid to any Lender for the use, forbearance or
detention of sums due hereunder shall, to the extent permitted by law applicable
to such Lender, be amortized, prorated, allocated and spread throughout the full
term of the Loans evidenced by the Notes until payment in full so that the rate
or amount of interest on account of any Loans hereunder does not exceed the
maximum amount allowed by such applicable law. If at any time and from time to
time (i) the amount of interest payable to any Lender on any date shall be
computed at the Highest Lawful Rate applicable to such Lender pursuant to this
Section 13.14 and (ii) in respect of any subsequent interest computation period
the amount of interest otherwise payable to such Lender would be less than the
amount of interest payable to such Lender

-106-

--------------------------------------------------------------------------------

 

computed at the Highest Lawful Rate applicable to such Lender, then the amount
of interest payable to such Lender in respect of such subsequent interest
computation period shall continue to be computed at the Highest Lawful Rate
applicable to such Lender until the total amount of interest payable to such
Lender shall equal the total amount of interest which would have been payable to
such Lender if the total amount of interest had been computed without giving
effect to this Section 13.14. To the extent that Chapter 303 of the Texas
Finance Code is relevant for the purpose of determining the Highest Lawful Rate,
such Lender elects to determine the applicable rate ceiling under such Chapter
by the indicated weekly rate ceiling from time to time in effect.
     Section 13.15 Confidentiality. For the purposes of this Section 13.15,
“Confidential Information” means information about any Borrower furnished by any
Borrower or its Affiliates (collectively, the “Disclosing Parties”) to the
Administrative Agents or any of the Lenders, including, but not limited to, any
actual or pending agreement, business plans, budgets, projections, ecological
data and accounting records, financial statements, or other financial data of
any kind, any title documents, reports or other information relating to matters
of title, any projects or plans, whether actual or prospective, and any other
documents or items embodying any such Confidential Information; provided that
such term does not include information that (a) was publicly known or otherwise
known prior to the time of such disclosure, (b) subsequently becomes publicly
known through no act or omission by the Administrative Agents or the Lenders or
any Person acting on behalf thereof, (c) otherwise becomes known to the
Administrative Agents or Lenders other than through disclosure by the Disclosing
Parties or a party known to be subject to a confidentiality agreement or
(d) constitutes financial statements delivered to the Administrative Agents and
the Lenders under Section 9.01(a) that are otherwise publicly available. The
Administrative Agents and the Lenders will maintain the confidentiality of such
Confidential Information delivered to (i) such Person, provided that each such
Person (a “Restricted Person”) may deliver or disclose Confidential Information
to such Restricted Person’s directors, officers, employees, agents, attorneys
investment advisors, trustees and Affiliates, who agree to hold confidential the
Confidential Information substantially in accordance with the terms of this
Section 13.15, (ii) such Restricted Person’s financial advisors and other
professional advisors who agree to hold confidential the Confidential
Information substantially in accordance with the terms of this Section 13.15,
(iii) any other Lender, (iv) any pledgee referred to in Section 13.06(e) or any
assignee to which such Restricted Person sells or offers to sell its Note or any
part thereof or any participation therein (if such Person has agreed in writing
prior to its receipt of such Confidential Information to be bound by the
provisions of this Section 13.15), (v) any Person from which such Restricted
Person offers to purchase any security of the Borrowers (if such Person has
agreed in writing prior to its receipt of such Confidential Information to be
bound by the provisions of this Section 13.15), (vi) any Governmental Authority
having jurisdiction or any self-regulatory body claiming to have authority over
such Restricted Person, (vii) the National Association of Insurance
Commissioners or any similar organization, or any nationally recognized rating
agency that requires access to information about such Restricted Person’s
investment portfolio, or (viii) any other Person to which such delivery or
disclosure may be necessary or appropriate (A) to effect compliance with any
Governmental Requirement applicable to such Restricted Person, (B) in response
to any subpoena or other legal process, (C) in connection with any litigation to
which such Restricted Person is a party or (D) if an Event of Default has
occurred and is continuing, to the extent such Restricted Person may reasonably
determine such delivery and disclosure to be necessary or appropriate in the
enforcement or for the protection of its rights and remedies under the Notes

-107-

--------------------------------------------------------------------------------

 

and this Agreement. Each Lender, by its acceptance of a Note or a participation
agreement, will be deemed to have agreed to be bound by and to be entitled to
the benefits of this Section 13.15 as though it were a party to this Agreement.
On reasonable request by any Borrower in connection with the delivery to any
Lender of information required to be delivered to such Lender under this
Agreement or requested by such Lender (other than a Lender that is a party to
this Agreement or its nominee), such Lender will enter into an agreement with
any Borrower embodying the provisions of this Section 13.15. Each Borrower
waives (on its own behalf and on behalf of its Subsidiaries) any and all other
rights it (or its Subsidiaries) may have to confidentiality as against the
Administrative Agents and the Lenders arising by or under any contract,
agreement, statute or law except as expressly stated in this Section 13.15.
     Section 13.16 Effectiveness. This Agreement shall be effective on the
Closing Date.
     Section 13.17 Exculpation Provisions. Each of the parties hereto
specifically agrees that it has a duty to read this Agreement and the Security
Instruments and agrees that it is charged with notice and knowledge of the terms
of this Agreement and the Security Instruments; that it has in fact read this
Agreement and is fully informed and has full notice and knowledge of the terms,
conditions and effects of this Agreement; that it has been represented by
independent legal counsel of its choice throughout the negotiations preceding
its execution of this Agreement and the Security Instruments; and has received
the advice of its attorney in entering into this Agreement and the Security
Instruments; and that it recognizes that certain of the terms of this Agreement
and the Security Instruments result in one party assuming the liability inherent
in some aspects of the transaction and relieving the other party of its
responsibility for such liability. Each party hereto agrees and covenants that
it will not contest the validity or enforceability of any exculpatory provision
of this Agreement and the Security Instruments on the basis that the party had
no notice or knowledge of such provision or that the provision is not
“conspicuous.”
     Section 13.18 Hedging Agreements. Notwithstanding anything to the contrary
contained herein, the terms and provisions of this Agreement shall not apply to
any Hedging Agreements, except to the extent necessary for all Hedging
Agreements with Lenders and/or their Lender Affiliate to be secured by the
Security Instruments on a pari passu basis with other Indebtedness and for the
proceeds from the Security Instruments to be applied as set forth in Section
11.02(d) hereof.
     Section 13.19 USA Patriot Act Notice. Each US Lender hereby notifies the
Borrowers that pursuant to the requirements of the USA Patriot Act (Title III of
Pub. L. 107-56 (signed into law October 26, 2001)) (the “USA Patriot Act”), it
is required to obtain, verify and record information that identifies each US
Borrower and their Subsidiaries, which information includes the name and address
of each US Borrower and such Subsidiaries and other information that will allow
such US Lender to identify each US Borrower and such Subsidiaries in accordance
with the USA Patriot Act.
     Section 13.20 Restatement. This Agreement amends, restates and supercedes
the Existing Credit Agreement. It is the intention of the parties that all Liens
and security interests securing the Existing Credit Agreement continue to exist,
remain valid and shall not be impaired

-108-

--------------------------------------------------------------------------------

 

or released hereby and shall remain in full force and effect as provided in the
Security Instruments.
ARTICLE XIV

     Section 14.01 The Guaranty.
          (a) The Guarantors irrevocably and unconditionally, jointly and
severally, guarantee to each Canadian Tranche Revolving Lender and the

          (b) The Guarantors further agree that this Guaranty constitutes an
absolute, irrevocable, complete and continuing guarantee of payment, performance
and compliance and not merely of collection.
          (c) The obligations of the Guarantors to make any payment hereunder
may be satisfied by causing the Canadian Borrowers to make such payment.
          (d) The Guarantors also agree to pay any and all costs and expenses

Administrative Agent or any Canadian Tranche Revolving Lender against the
Canadian Borrowers or any other Person or against such Applicable Administrative
Agent or any Canadian Tranche Revolving Lender for their payments in respect of

          (e) The Guarantors waive presentment to, demand of payment from and
protest to the Canadian Borrowers of any of the Guaranteed Obligations, and also
waives notice of acceptance of its guarantee and notice of protest for

right or remedy against the Canadian Borrowers or any other Person under the
provisions of this Agreement, any other Loan Document or otherwise.
          (f) To the fullest extent permitted by applicable law, the obligations
of the Guarantors hereunder are absolute and unconditional and shall not be
subject to any reduction, limitation, impairment or termination for any reason

any of the Guaranteed Obligations, and shall not be subject to any defense
(other than a defense of payment or performance), set-off, counterclaim,
recoupment or termination whatsoever by reason of the invalidity, illegality or
unenforceability of the Guaranteed Obligations or any Note, other Loan Document
or otherwise.

-109-

--------------------------------------------------------------------------------

 

     (g) The Guarantors waive any defense based on or arising out of any defense
of the Canadian Borrowers or the unenforceability of the Guaranteed Obligations
or any part thereof from any cause, or the cessation from any cause of the
liability of the Canadian Borrowers, other than the final payment in full in
cash of all the Guaranteed Obligations.
     (h) To the fullest extent permitted by applicable law, this Guaranty shall
continue to be effective or be reinstated, as the case may be, if at any time
any payment of the Guaranteed Obligations is rescinded or must otherwise be
returned by any of the Canadian Tranche Revolving Lenders upon the insolvency,
bankruptcy or reorganization or the Canadian Borrowers or otherwise, all as
though such payment had not been made.
     Section 14.02 Subrogation. The Guarantors shall be subrogated to any of the
rights (whether contractual, under applicable laws or otherwise) of either of
the Administrative Agents or any Canadian Tranche Revolving Lender against the
Canadian Borrowers or any other Person for the payments in respect of any
amounts to any Canadian Tranche Revolving Lender pursuant to the provisions of
this Guaranty; provided, however, that the Guarantor shall not be entitled to
enforce, or to receive any payments arising out of or based upon, such right of
subrogation until all other Guaranteed Obligations shall have been paid in full
and the Canadian Allocated Total Commitments terminated.
