immediately after giving effect to the effectiveness of this Amendment, the Applicable
Percentage of each Lender to the Credit Agreement and the portion of the relevant
Commitment of each Lender, shall be as set forth on Annex I, as amended hereby
(it being understood that if any Letters of Credit are outstanding under the Credit

Eurodollar Loans or (b) entitle any Lender to any reimbursement under Section 5.02
of the Credit Agreement.

     28. Counterparts. This Amendment may be signed in any number of counterparts, which
may be delivered in original, electronic or facsimile form each of which shall be construed as an
original, but all of which together shall constitute one and the same instrument.

construed in accordance with, and governed by, the laws of New York and of the United States.

     30. Final Agreement of the Parties. Any previous agreement among the parties with
respect to the subject matter hereof is superseded by the Credit Agreement, as amended by this
Amendment. Nothing in this Amendment, express or implied is intended to confer upon any party
other than the parties hereto any rights, remedies, obligations or liabilities under or by reason
of this Amendment.

The Credits

     SECTION 2.1 The Facility; Commitments. Subject to the terms and conditions set
forth herein, each Lender agrees to make Loans to Borrower and to acquire participations in Letters
of Credit hereunder from time to time during the Availability Period, in an aggregate principal
amount up to, but not to exceed, the amount of such Lender’s Commitment, provided that such Loans
and Letter of Credit participations will not result in (a) such Lender’s Credit Exposure exceeding
such Lender’s Commitment or (b) the sum of the total Credit Exposures of all Lenders hereunder
exceeding the sum of their total Commitments. Subject to the conditions herein, Borrower may
borrow, prepay and reborrow Loans.

     SECTION 2.2 Loans and Borrowings.

     (a) Each Loan shall be made as part of a Borrowing consisting of Loans made by the Lenders
ratably in accordance with their respective Commitments. The failure of any Lender to make any
Loan required to be made by it shall not relieve any other Lender of its obligations hereunder;
provided that the Commitments of the Lenders are several and no Lender shall be responsible for any
other Lender’s failure to make Loans as required.

     (b) Subject to Section 2.13, each Borrowing shall be comprised entirely of ABR Loans
or Eurodollar Loans as Borrower may request in accordance herewith. Each Lender at its option may
make any Eurodollar Loan by causing any domestic or foreign branch or Affiliate of such Lender to
make such Loan; provided that any exercise of such option shall not affect the obligation of
Borrower to repay such Loan in accordance with the terms of this Agreement.

     (c) At the commencement of each Interest Period for any Eurodollar Borrowing, such Borrowing
shall be in an aggregate amount that is an integral multiple of $1,000,000 and not less than
$5,000,000 (including any continuation or conversion of existing Loans made in connection
therewith). At the time that each ABR Borrowing is made, such Borrowing shall be in an aggregate
amount that is an integral multiple of $1,000,000 and not less than $5,000,000 (including any
continuation or conversion of existing Loans made in connection therewith); provided that an ABR
Borrowing may be in an aggregate amount that is equal to the entire unused balance of the total
Commitments or that is required to finance the reimbursement of an LC Disbursement as contemplated
by Section 2.4(e). Borrowings of more than one Type and Class may be outstanding at the
same time; provided that there shall not at any time be more than a total of ten (10)
Eurodollar Borrowings outstanding.

     (d) Notwithstanding any other provision of this Agreement, Borrower shall not be entitled to
request, or to elect to convert or continue, any Borrowing if the Interest Period requested with
respect thereto would end after the Maturity Date.

16

 

     SECTION 2.3 Requests for Borrowings. To request a Borrowing, Borrower shall notify
the Administrative Agent of such request by telephone (a) in the case of a Eurodollar Borrowing,
not later than 1:00 p.m., New York City time, three Business Days before the date of the proposed
Borrowing or (b) in the case of an ABR Borrowing, not later than 11:00 a.m., New York City time, on
the date of the proposed Borrowing; provided that any such notice of an ABR Borrowing to
finance the reimbursement of an LC Disbursement as contemplated by Section 2.4(e) may be
given not later than 12:00 p.m. (noon), New York City time. Each such telephonic Borrowing Request
shall be irrevocable and shall be confirmed promptly by hand delivery or telecopy to the
Administrative Agent of a written Borrowing Request in a form approved by the Administrative Agent
and signed by Borrower. Each such telephonic and written Borrowing Request shall specify the
following information in compliance with Section 2.2:

     (i) the aggregate amount of the requested Borrowing;

     (ii) the date of such Borrowing, which shall be a Business Day;

     (iii) whether such Borrowing is to be an ABR Borrowing or a Eurodollar Borrowing; and

     (iv) in the case of a Eurodollar Borrowing, the initial Interest Period to be
applicable thereto, which shall be a period contemplated by the definition of the term
“Interest Period”.

If no election as to the Type of Borrowing is specified, then the requested Borrowing shall be an
ABR Borrowing. If no Interest Period is specified with respect to any requested Eurodollar
Borrowing, then Borrower shall be deemed to have selected an Interest Period of one month’s
duration. Promptly following receipt of a Borrowing Request in accordance with this Section, the
Administrative Agent shall advise each Lender of the details thereof and of the amount of such
Lender’s Loan to be made as part of the requested Borrowing.

     SECTION 2.4 Letters of Credit.

     (a) Subject to the terms and conditions set forth herein, the Borrower may request the
issuance of Letters of Credit for its own account or the account of any Subsidiary, in a form
reasonably acceptable to the Administrative Agent and the applicable Issuing Bank, at any time and
from time to time during the Availability Period, and (subject to the conditions set forth in
Section 4.2), the applicable Issuing Bank will issue such Letters of Credit. The Borrower
unconditionally and irrevocably agrees that, in connection with any Letter of Credit issued for the
account of any Subsidiary as provided in the first sentence of this paragraph, it will be fully
responsible for the reimbursement of LC Disbursements, the payment of interest thereon and the
payment of fees due under Section 2.11(b) to the same extent as if it were the sole account
party in respect of such Letter of Credit. In the event of any inconsistency between the terms and
conditions of this Agreement and the terms and conditions of any form of letter of credit
application or other agreement submitted to, or entered into with, any Issuing Bank relating to any
Letter of Credit, the terms and conditions of this Agreement shall control.

     (b) To request the issuance of a Letter of Credit (or the amendment, renewal or extension of
an outstanding Letter of Credit), the Borrower shall hand deliver or telecopy (or

17

 

transmit by
electronic communication, if arrangements for doing so have been approved by the applicable Issuing
Bank) to an Issuing Bank and the Administrative Agent (reasonably, but no less than five (5)
Business Days, in advance of the requested date of issuance, amendment, renewal or extension) a
notice requesting the issuance of a Letter of Credit, or identifying the Letter of Credit to be
amended, renewed or extended, and specifying the date of issuance, amendment, renewal or extension
(which shall be a Business Day), the date on which such Letter of Credit is to expire (which shall
comply with paragraph (c) below), the amount of such Letter of Credit, the name and address of the
beneficiary thereof, whether such Letter of Credit is a Financial Letter of Credit or a Performance
Letter of Credit (subject to confirmation of such status by the Administrative Agent and the
applicable Issuing Bank, acting reasonably and in consultation with the Borrower) and such other
information as shall be necessary to prepare, amend, renew or extend such Letter of Credit. If
requested by the applicable Issuing Bank, the Borrower also shall submit a letter of credit
application on such Issuing Bank’s standard form in connection with any request for a Letter of
Credit; provided, however, that to the extent such application contains terms and
conditions that are inconsistent with the terms and conditions of this Agreement, the application
shall be conformed to the terms and conditions of this Agreement. A Letter of Credit shall be
issued, amended, renewed or extended only if (and upon issuance, amendment, renewal or extension of
each Letter of Credit the Borrower shall be deemed to represent and warrant that), after giving
effect to such issuance, amendment, renewal or extension (i) the LC Exposure shall not exceed
$250,000,000, (ii) the total Credit Exposure shall not exceed the total Commitments and (iii)
following the effectiveness of any Maturity Date extension request, the LC Exposure in respect of
all Letters of Credit having an expiration date after the previously effective Maturity Date shall
not exceed the aggregate Commitments of the consenting Lenders extended pursuant to Section
2.6; provided that an Issuing Bank shall not issue, amend, renew or extend any Letter
of Credit (other than automatic renewals thereof pursuant to customary evergreen provisions or
amendments that do not effect an extension, or increase the stated face amount, of such Letter of
Credit) if it shall have been notified by the Administrative Agent at the written request of the
Required Lenders that a Default or an Event of
Default has occurred and is continuing and that, as a result, no further Letters of Credit
shall be issued by it (a “Letter of Credit Suspension Notice”); provided
however that such Issuing Bank shall have received such Letter of Credit Suspension Notice
within a sufficient amount of time to process internally the instructions therein contained. Each
determination as to whether a Letter of Credit constitutes a Financial Letter of Credit or a
Performance Letter of Credit shall be made by the Administrative Agent and the applicable Issuing
Bank, acting reasonably and in consultation with the Borrower and, once made, shall be conclusive
and binding upon the Borrower, the Lenders and the Issuing Banks.

     (c) Each Letter of Credit shall expire at or prior to the close of business not later than the
earlier of (i) the date one year after the date of issuance of such Letter of Credit (or, in the
case of any renewal or extension thereof one year after such renewal or extension) and (ii) the
then effective Maturity Date; provided that any Letter of Credit may provide for the
renewal thereof for additional periods (which shall in no event extend beyond the date referred to
in clause (ii) above) upon notice by Borrower delivered to the Issuing Lender not less than ten
(10) days before the then effective expiration date. Notwithstanding the foregoing, any Letter of
Credit issued hereunder may, in the sole discretion of the applicable Issuing Bank, expire after
the Maturity Date but on or before the date that is 90 days after the Maturity Date,
provided that the Borrower hereby agrees that it shall provide cash collateral in an amount
equal to 102% of

18

 

the LC Exposure in respect of any such outstanding Letter of Credit to the
applicable Issuing Bank at least five (5) days prior to the Maturity Date, which such amount shall
be (i) deposited by the Borrower in an account in the name of the Borrower at, and for the benefit
of, such Issuing Bank and (ii) held by such Issuing Bank for, and until, the satisfaction of the
Borrower’s reimbursement obligations in respect of such Letter of Credit until the expiration of
such Letter of Credit. The Issuing Bank shall have exclusive dominion and control, including the
exclusive right of withdrawal, over such account. Other than any interest earned on the deposit or
through the investment of such deposits, which investments, if any, shall be made by the Issuing
Bank, at its option and reasonable discretion, in consultation with the Borrower, and at the
Borrower’s risk and expense, such deposits shall not bear interest. Interest or profits, if any,
on such investments shall accumulate in such account. Any Letter of Credit issued with an
expiration date beyond the Maturity Date shall, to the extent of any undrawn amount remaining
thereunder on the Maturity Date, cease to be a “Letter of Credit” outstanding under this Agreement
for purposes of the Lenders’ obligations to participate in Letters of Credit pursuant to
Section 2.4(d). For the avoidance of doubt, if the Maturity Date shall be extended pursuant
to Section 2.6, “Maturity Date” as referenced in this sentence shall refer to the Maturity
Date as extended pursuant to Section 2.6; provided that, notwithstanding anything
in this Agreement (including Section 2.6 hereof) or any other Loan Document to the
contrary, the Maturity Date and the Availability Period, as such terms are used in reference to any
Issuing Bank or any Letter of Credit issued thereby, may not be extended with respect to any
Issuing Bank without the prior written consent of such Issuing Bank. If the Borrower is required
to provide an amount of cash collateral pursuant to this Section 2.4(c), such amount
including any accumulated interest or profit (to the extent not applied as aforesaid) shall be
returned to the Borrower within three (3) Business Days after the expiration of the final Letter of
Credit secured by such amounts and, to the extent applicable, any lien related to the cash
collateral shall be released by the Issuing Bank.

     (d) By the issuance of a Letter of Credit (or an amendment to a Letter of Credit increasing
the amount thereof) and without any further action on the part of the applicable Issuing Bank or
the Lenders, such Issuing Bank hereby grants to each Lender, and each such Lender hereby acquires
from such Issuing Bank, a participation in such Letter of Credit equal to such Lender’s Applicable
Percentage of the aggregate amount available to be drawn under such Letter of Credit. In
consideration and in furtherance of the foregoing, each such Lender hereby absolutely and
unconditionally agrees to pay to the Administrative Agent, for the account of the applicable
Issuing Bank, such Lender’s Applicable Percentage of each LC Disbursement made by such Issuing Bank
and not reimbursed by the Borrower on the date due as provided in Section 2.4(e), or of any
reimbursement payment required to be refunded to the Borrower for any reason. Each Lender
acknowledges and agrees that its obligation to acquire participations pursuant to this paragraph in
respect of Letters of Credit is absolute and unconditional and shall not be affected by any
circumstance whatsoever, including any amendment, renewal or extension of any Letter of Credit
(provided that such Letter of Credit shall expire no later than the date set forth in Section
2.4(c)), or the occurrence and continuance of a Default or reduction or termination of the
Commitments, and that each such payment shall be made without any offset, abatement, withholding or
reduction whatsoever.

     (e) If any Issuing Bank shall make any LC Disbursement in respect of a Letter of Credit, the
Borrower shall reimburse or cause reimbursement of such LC Disbursement by paying or causing to be
paid to the Administrative Agent an amount equal to such LC

19

 

Disbursement not later than 2:00 p.m., New York City time, on the Business Day immediately following the date on which the Borrower shall
have received notice of such LC Disbursement; provided that the Borrower may, subject to the
conditions to borrowing set forth herein, request in accordance with Section 2.3 that such
payment be financed with an ABR Borrowing in an equivalent amount and, to the extent so financed,
the Borrower’s obligation to make such payment or cause it to be made shall be discharged and
replaced by the resulting ABR Borrowing. If the Borrower fails to make such payment or cause it to
be made when due, the Administrative Agent shall notify each Lender of the applicable LC
Disbursement, the payment then due from the Borrower in respect thereof and such Lender’s
Applicable Percentage thereof. Promptly following receipt of such notice, each Lender shall pay to
the Administrative Agent its Applicable Percentage of the payment then due from the Borrower, in
the same manner as provided in Section 2.5 with respect to Loans made by such Lender (and
Section 2.5 shall apply, mutatis mutandis, to the payment obligations of the Lenders), and
the Administrative Agent shall promptly pay to the applicable Issuing Bank the amounts so received
by it from the Lenders. Promptly following receipt by the Administrative Agent of any payment from
the Borrower or any Subsidiary pursuant to this paragraph, the Administrative Agent shall
distribute such payment to the applicable Issuing Bank or, to the extent that Lenders have made
payments pursuant to this paragraph to reimburse such Issuing Bank, then to such Lenders and such
Issuing Bank as their interests may appear. Any payment made by a Lender pursuant to this
paragraph to reimburse such Issuing Bank for any LC Disbursement (other than the funding of ABR
Loans as contemplated above) shall not constitute a Loan and shall not relieve the Borrower of its
obligation to reimburse such LC Disbursement.

     (f) To the extent permitted by applicable law, the Borrower’s obligation to reimburse LC
Disbursements as provided in Section 2.4(e) shall be absolute, unconditional and
irrevocable,
and shall be performed strictly in accordance with the terms of this Agreement under any and
all circumstances whatsoever and irrespective of (i) any lack of validity or enforceability of any
Letter of Credit or this Agreement, or any term or provision therein, (ii) any draft or other
document presented under a Letter of Credit proving to be forged, fraudulent or invalid in any
respect or any statement therein being untrue or inaccurate in any respect, (iii) payment by the
Issuing Bank under a Letter of Credit against presentation of a draft or other document that does
not comply with the terms of such Letter of Credit, or (iv) any other event or circumstance
whatsoever, whether or not similar to any of the foregoing, that might, but for the provisions of
this Section 2.4, constitute a legal or equitable discharge of, or provide a right of
setoff against, the Borrower’s obligations hereunder. To the extent permitted by applicable law,
neither the Administrative Agent, the Lenders nor any of the Issuing Banks, nor any of their
Related Parties, shall have any liability or responsibility by reason of or in connection with the
issuance or transfer of any Letter of Credit or any payment or failure to make any payment
thereunder (irrespective of any of the circumstances referred to in the preceding sentence), or any
error, omission, interruption, loss or delay in transmission or delivery of any draft, notice or
other communication under or relating to any Letter of Credit (including any document required to
make a drawing thereunder), any error in interpretation of technical terms or any consequence
arising from causes beyond the control of the applicable Issuing Bank; provided that the
foregoing shall not be construed to excuse any Issuing Bank from liability to the Borrower to the
extent of any direct damages (as opposed to special, indirect, consequential or punitive damages,
claims in respect of which are hereby waived by the Borrower to the extent permitted by applicable
law) suffered by the Borrower that are caused by such Issuing Bank’s failure to

20

 

exercise care when
determining whether drafts and other documents presented under a Letter of Credit comply with the
terms thereof. The parties hereto expressly agree that, in the absence of gross negligence or
willful misconduct on the part of the applicable Issuing Bank (as finally determined by a court of
competent jurisdiction), such Issuing Bank shall be deemed to have exercised care in each such
determination. In furtherance of the foregoing and without limiting the generality thereof, the
parties agree that, with respect to documents presented which appear on their face to be in
substantial compliance with the terms of a Letter of Credit, the applicable Issuing Bank may, in
its sole discretion, either accept and make payment upon such documents without responsibility for
further investigation, regardless of any notice or information to the contrary, or refuse to accept
and make payment upon such documents if such documents are not in strict compliance with the terms
of such Letter of Credit.

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

     (h) If an Issuing Bank shall make any LC Disbursement, then, unless the Borrower shall
reimburse such LC Disbursement in full on the date such LC Disbursement is made, the unpaid amount
thereof shall bear interest, for each day from and including the date such LC Disbursement is made
to but excluding the date that the Borrower reimburses such LC
Disbursement, at the rate per annum then applicable to ABR Loans; provided that, if
the Borrower fails to reimburse such LC Disbursement by the date that is three (3) Business Days
following the date such reimbursement is due pursuant to Section 2.4(e), then Section
2.12(d) shall apply. Interest accrued pursuant to this paragraph shall be for the account of
the applicable Issuing Bank, except that interest accrued on and after the date of payment by any
Lender pursuant to Section 2.4(e) to reimburse such Issuing Bank shall be for the account
of such Lender to the extent of such payment.

     (i) If any Event of Default described in Section 8.1(a) shall occur and be continuing,
on the Business Day that the Borrower receives notice from the Administrative Agent or the Required
Lenders demanding the deposit of cash collateral pursuant to this paragraph, the Borrower shall
deposit in an account with the Administrative Agent, in the name of the Administrative Agent and
for the benefit of the Lenders, an amount in cash equal to the LC Exposure 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 (i) occurrence of any Event of
Default with respect to the Borrower described in Section 8.1(g) or (ii) acceleration of
the maturity of the Loans and termination of the Commitments pursuant to Section 8.3.
Each such deposit shall be held by the Administrative Agent as collateral for the payment and
performance of the obligations of the Borrower under this Agreement in accordance with this
paragraph. The 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

21

 

the option and sole discretion of the Administrative Agent and at the Borrower’s 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 Administrative Agent to reimburse the Issuing Banks for LC
Disbursements for which they have not been reimbursed and, to the extent not so applied, shall be
held for the satisfaction of the reimbursement obligations of the Borrower for the LC Exposure at
such time or, if the maturity of the Loans has been accelerated, be applied to satisfy other
obligations of the Borrower under this Agreement. If the Borrower is required to provide an amount
of cash collateral hereunder as a result of the occurrence of an Event of Default, such amount
including any accumulated interest or profit (to the extent not applied as aforesaid) shall be
returned to the Borrower within three (3) Business Days after all Events of Default have been cured
or waived and, to the extent applicable, any lien related to the cash collateral shall be released
by the Administrative Agent.

     (j) The Borrower may, at any time and from time to time, upon notice to the Administrative
Agent, designate as additional Issuing Banks one or more Lenders that agree to serve in such
capacity as provided below. The acceptance by a Lender of an appointment as an Issuing Bank
hereunder shall be evidenced by an agreement, which shall be in form and substance reasonably
satisfactory to such additional Issuing Bank, executed by the Borrower, the Administrative Agent
and such additional Issuing Bank and, from and after the effective date of such agreement, (i) such
Lender shall have all the rights and obligations of an Issuing Bank under this Agreement and (ii)
references herein to the term “Issuing Bank” shall be deemed to include such Lender in its capacity
as an issuer of Letters of Credit hereunder.

     (k) The Borrower may terminate the appointment of any Issuing Bank as an “Issuing Bank”
hereunder by providing a written notice thereof to such Issuing Bank, with a copy to the
Administrative Agent. Any such termination shall become effective upon the earlier of (i) such
Issuing Bank acknowledging receipt of such notice and (ii) the 10th Business Day following the date
of the delivery thereof; provided that no such termination shall become effective until and unless
the LC Exposure attributable to Letters of Credit issued by such Issuing Bank (or its Affiliates)
shall have been reduced to zero. At the time any such termination shall become effective, the
Borrower shall pay all unpaid fees accrued for the account of the terminated Issuing Bank pursuant
to Section 2.11(b). Notwithstanding the effectiveness of any such termination, the
terminated Issuing Bank shall remain a party hereto and shall continue to have all the rights of an
Issuing Bank under this Agreement with respect to Letters of Credit issued by it prior to such
termination, but shall not issue any additional Letters of Credit. Without limiting the foregoing,
following the delivery by the Borrower of any notice of termination in respect of any Issuing Bank
(and regardless of whether such notice has become effective), such Issuing Bank shall have no
obligation to issue, amend, renew or extend any Letter of Credit.

     SECTION 2.5 Funding of Borrowings.

     (a) Each Lender shall make each Loan to be made by it hereunder on the proposed date thereof
by wire transfer of immediately available funds by 1:00 p.m., New York City time, to the account of
the Administrative Agent most recently designated by it for such purpose by notice to the Lenders.
The Administrative Agent will make such Loans available to Borrower by promptly crediting the
amounts so received, in like funds, to an account of Borrower designated by Borrower from time to
time in a written notice to the Administrative Agent executed by two

22

 

Authorized Officers of Borrower; provided that ABR Loans made to finance the reimbursement of an LC Disbursement
as provided in Section 2.4(e) shall be remitted by the Administrative Agent to the
applicable Issuing Bank.

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

     SECTION 2.6 Extension of Maturity Date and of Commitments.

     (a) Subject to the other provisions of this Agreement and provided that no Event of Default
has occurred and is continuing, the total Commitments shall be effective for an initial period from
the Effective Date to the Original Maturity Date; provided that the applicable Maturity
Date, and concomitantly the total Commitments, may be extended (but not more than twice during the
life of this Agreement) for successive one year periods expiring on the date which is one year from
the then scheduled Maturity Date. If Borrower shall request in a Certificate of Extension
delivered to the Administrative Agent at least 45 days but no more than 90 days prior to a date
which is an anniversary of the date of this Agreement that the Maturity Date be extended for one
year from the then scheduled Maturity Date, then the Administrative Agent shall promptly notify
each Lender of such request and each Lender shall notify the Administrative Agent, no later than 30
days prior to such anniversary of the date of this Agreement, whether such Lender, in the exercise
of its sole discretion, will extend the Maturity Date for such one year period. Any Lender which
shall not timely notify the Administrative Agent whether it will extend the Maturity Date shall be
deemed to not have agreed to extend the Maturity Date. No Lender shall have any obligation
whatsoever to agree to extend the Maturity Date. Any agreement to extend the Maturity Date by any
Lender shall be irrevocable, except as provided in Section 2.6(c).

     (b) If all Lenders notify the Administrative Agent pursuant to clause (a) of this Section
2.6 of their agreement to extend the Maturity Date, then the Administrative Agent shall so
notify each Lender and Borrower, and such extension shall be effective without other or further
action by any party hereto for such additional one-year period.

     (c) If Lenders constituting at least the Required Lenders approve the extension of the then
scheduled Maturity Date (such Lenders agreeing to extend the Maturity Date herein called

23

 

the “Accepting Lenders”) and if one or more Lenders shall notify, or be deemed to notify, the
Administrative Agent pursuant to clause (a) of this Section 2.6 that they will not extend
the then scheduled Maturity Date (such Lenders herein called the “Declining Lenders”), then
(A) the Administrative Agent shall promptly so notify Borrower and the Accepting Lenders, (B) the
Accepting Lenders shall, upon Borrower’s election to extend the then scheduled Maturity Date in
accordance with clause (i) or (ii) below, extend the then scheduled Maturity Date and (C) Borrower
shall, pursuant to a notice delivered to the Administrative Agent, the Accepting Lenders and the
Declining Lenders, no later than the tenth (10th) day following the date by which each Lender is
required, pursuant to Section 2.6(a), to approve or disapprove the requested extension of
the total Commitments, either:

     (i) elect to extend the Maturity Date and direct the Declining Lenders to terminate
their Commitments, which termination shall become effective on the date which would have
been the Maturity Date except for the operation of this Section. On the date which would
have been the Maturity Date except for the operation of this Section, (x) Borrower shall
deliver a notice of the effectiveness of such termination to the Declining Lenders with a
copy to the Administrative Agent and (y) Borrower shall pay in full in immediately available
funds all Obligations of Borrower owing to the Declining Lenders, including any amounts
required pursuant to Section 2.15, and (z) upon the occurrence of the events set forth in clauses (x) and (y), the Declining Lenders shall
each cease to be a Lender hereunder for all purposes, other than for purposes of
Sections 2.14 through 2.17 and Section 10.3, and shall cease to have
any obligations or any Commitment hereunder, other than to the Agents pursuant to
Article IX, and the Administrative Agent shall promptly notify the Accepting Lenders
and Borrower of the new Commitments; or

     (ii) elect to extend the Maturity Date and, prior to or no later than the then
scheduled Maturity Date, (A) to replace one or more of the Declining Lenders with another
lender or lenders reasonably acceptable to the Administrative Agent (such lenders herein
called the “Replacement Lenders”) and (B) Borrower shall pay in full in immediately
available funds all Obligations of Borrower owing to any Declining Lenders which are not
being replaced, as provided in clause (i) above; provided that (x) any Replacement
Lender shall purchase, and any Declining Lender shall sell, such Declining Lender’s rights
and obligations hereunder without recourse or expense to, or warranty by, such Declining
Lender being replaced for a purchase price equal to the aggregate outstanding principal
amount of the Obligations payable to such Declining Lender plus any accrued but unpaid
interest on such Obligations and accrued but unpaid fees or other amounts owing in respect
of such Declining Lender’s Loans and Commitments hereunder, including compensation for any
break funding, to the extent required by Section 2.15, and (y) upon the payment of
such amounts referred to in clause(x) and the execution of an Assignment and Acceptance by
such Replacement Lender and such Declining Lender, such Replacement Lender shall constitute
a Lender hereunder and such Declining Lender being so replaced shall no longer constitute a
Lender (other than for purposes of Sections 2.14 through 2.17 and
Section 10.3), and shall no longer have any obligations hereunder, other than to the
Agents pursuant to Article IX; or

24

 

     (iii) elect to revoke and cancel the extension request in such Certificate of Extension
by giving notice of such revocation and cancellation to the Administrative Agent (which
shall promptly notify the Lenders thereof) no later than the tenth (10th) day following the
date by which each Lender is required, pursuant to clause (a) of this Section, to approve or
disapprove the requested extension of the Maturity Date, and concomitantly the total
Commitments.

If Borrower fails to timely provide the election notice referred to in this clause (c), Borrower
shall be deemed to have revoked and cancelled the extension request in the Certificate of Extension
and to have elected not to extend the Maturity Date.

     SECTION 2.7 Interest Elections.

     (a) Each Borrowing initially shall be of the Type specified in the applicable Borrowing
Request (or an ABR Borrowing if no Type is specified) and, in the case of a Eurodollar Borrowing,
shall have an initial Interest Period as specified in such Borrowing Request (or one month if no
Interest Period is specified). Thereafter, Borrower may elect to convert such Borrowing to a
different Type or to continue such Borrowing and, in the case of a Eurodollar Borrowing, may elect
Interest Periods therefor, all as provided in this Section.
Borrower may, subject to the requirements of Section 2.2(c), elect different options
with respect to different portions of the affected Borrowing, in which case each such portion shall
be allocated ratably among the Lenders holding the Loans comprising such Borrowing, and the Loans
comprising each such portion shall be considered a separate Borrowing.

     (b) To make an election pursuant to this Section, Borrower shall notify the Administrative
Agent of such election by telephone by the time that a Borrowing Request would be required under
Section 2.3 if Borrower were requesting a Borrowing of the Type resulting from such
election to be made on the effective date of such election. Each such telephonic Interest Election
Request shall be irrevocable and shall be confirmed promptly by hand delivery or telecopy to the
Administrative Agent of a written Interest Election Request signed by Borrower.

     (c) Each telephonic and written Interest Election Request shall specify the following
information in compliance with Section 2.2:

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

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

     (iii) whether the resulting Borrowing is to be an ABR Borrowing or a Eurodollar
Borrowing; and

25

 

     (iv) if the resulting Borrowing is a Eurodollar Borrowing, the Interest Period to be
applicable thereto after giving effect to such election, which shall be a period
contemplated by the definition of the term “Interest Period”.

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

     (d) Promptly following receipt of an Interest Election Request, the Administrative Agent shall
advise each Lender of the details thereof and of such Lender’s portion of each resulting Borrowing.

     (e) If Borrower fails to deliver a timely Interest Election Request with respect to a
Eurodollar Borrowing prior to the end of the Interest Period applicable thereto, then, unless such
Borrowing is repaid as provided herein, at the end of such Interest Period such Borrowing shall be
converted to an ABR Borrowing. Notwithstanding any contrary provision hereof, if an Event of
Default has occurred and is continuing and the Administrative Agent, at the request of the Required
Lenders, so notifies Borrower, then, so long as an Event of Default is continuing, (i) no
outstanding Borrowing may be converted to or continued as a Eurodollar Borrowing and (ii)
unless repaid and provided the Indebtedness has not been accelerated pursuant to Section
8.3, each Eurodollar Borrowing shall be converted to an ABR Borrowing at the end of the
Interest Period applicable thereto.

     SECTION 2.8 Termination and Reduction of Commitments.

     (a) Unless previously terminated, the Commitments shall terminate on the Maturity Date.

     (b) Borrower may at any time terminate, or from time to time reduce, the Commitments; provided
that (i) each reduction of the Commitments shall be in an amount that is an integral multiple of
$1,000,000 and not less than $5,000,000 and (ii) Borrower shall not terminate or reduce the
Commitments if, after giving effect to any concurrent prepayment of the Loans in accordance with
Section 2.10, the sum of the Credit Exposures would exceed the total Commitments.

     (c) Borrower shall notify the Administrative Agent of any election to terminate or reduce the
Commitments under paragraph (b) of this Section at least two Business Days prior to the effective
date of such termination or reduction, specifying such election and the effective date thereof.
Promptly following receipt of any notice, the Administrative Agent shall advise the Lenders of the
contents thereof. Each notice delivered by Borrower pursuant to this Section shall be irrevocable;
provided that a notice of termination of the Commitments delivered by Borrower may state that such
notice is conditioned upon the effectiveness of other credit facilities, in which case such notice
may be revoked by Borrower (by notice to the Administrative Agent on or prior to the specified
effective date) if such condition is not satisfied. Any termination or reduction of the
Commitments shall be permanent. Each reduction of the Commitments shall be made ratably among the
Lenders in accordance with their respective Commitments.

26

 

     SECTION 2.9 Repayment of Loans; Evidence of Debt.

     (a) Borrower hereby unconditionally promises to pay to the Administrative Agent for the
account of each Lender the then unpaid principal amount of each Loan on the Maturity Date or, if
earlier, the date on which the Commitment of such Lender relating to such Loan is terminated
(except for termination of the Commitment of the assigning Lender pursuant to Section
10.4(b)).

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

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

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

     (e) Any Lender may request that Loans made by it be evidenced by one or more promissory notes.
In such event, Borrower shall prepare, execute and deliver to such Lender promissory notes payable
to the order of such Lender (or, if requested by such Lender, to such Lender and its registered
assigns and in a form approved by the Administrative Agent). Thereafter, the Loans evidenced by
such promissory notes and interest thereon shall at all times (including after assignment pursuant
to Section 10.4) be represented by one or more promissory notes in such form payable to the
order of the payee named therein (or, if any such promissory note is a registered note, to such
payee and its registered assigns).

     SECTION 2.10 Prepayment of Loans.

     (a) Borrower shall have the right at any time and from time to time to prepay any Borrowing in
whole or in part, subject to prior notice in accordance with paragraph (b) of this Section.

     (b) Borrower shall notify the Administrative Agent by telephone (confirmed by telecopy) of any
prepayment hereunder (i) in the case of prepayment of a Eurodollar Borrowing, not later than 1:00
p.m., New York City time, three Business Days before the date of prepayment or (ii) in the case of
prepayment of an ABR Borrowing, not later than 11:00 a.m., New York City time, on the date of
prepayment. Each such notice shall be irrevocable and shall specify the prepayment date and the
principal amount of each Borrowing or portion thereof to be prepaid; provided that, if a notice of
prepayment is given in connection with a conditional notice of

27

 

termination of the Commitments as contemplated by Section 2.8, then such notice of
prepayment may be revoked if such notice of termination is revoked in accordance with Section
2.8. Promptly following receipt of any such notice relating to a Borrowing, the Administrative
Agent shall advise the Lenders of the contents thereof. Each partial prepayment of any Borrowing
shall be in an amount that would be permitted in the case of an advance of a Borrowing of the same
Type as provided in Section 2.2. Each prepayment of a Borrowing shall be applied ratably
to the Loans included in the prepaid Borrowing. Prepayments shall be accompanied by accrued
interest to the extent required by Section 2.12 and compensation for break funding, to the
extent required by Section 2.15.

     SECTION 2.11 Fees.

     (a) Borrower agrees to pay to the Administrative Agent for the account of each Lender on a pro
rata basis (based on Commitments) a facility fee (the “Facility Fee”), which Facility Fee
shall accrue at the Facility Fee Rate on the daily amount of the Commitments during the period from
and including the Effective Date to but excluding the Maturity Date; provided that if such
Lender continues to have any Credit Exposure after its Commitment terminates, then such Facility
Fee shall continue to accrue on the daily amount of such Lender’s Credit Exposure from and
including the date on which its Commitment terminates but excluding the date on which such Lender
ceases to have any Credit Exposure. Accrued Facility Fees shall be payable in arrears on the
first day of, April, July and October and the second day of January of each year, as applicable,
and on the Maturity Date, commencing on the first such date to occur after the Effective Date;
provided that any Facility Fees accruing as of the date on which the Commitments terminate
shall be payable on demand. All Facility Fees shall be computed on the basis of a year of 365 days
(or 366 days in a leap year) and shall be payable for the actual number of days elapsed (including
the first day but excluding the last day).

     (b) The Borrower agrees to pay (i) to the Administrative Agent for the account of each Lender
a commission with respect to all outstanding Letters of Credit, which shall accrue at a per annum
rate equal to the Eurodollar Margin then in effect on the face amount of each such Letter of Credit
during the period from and including the Effective Date to but excluding the later of the date on
which such Lender’s Commitment terminates and the date on which such Lender ceases to have any LC
Exposure, and (ii) to any Issuing Bank a fronting fee, which shall accrue at the rate or rates per
annum separately agreed upon between the Borrower and such Issuing Bank on the average daily amount
of the LC Exposure (excluding any portion thereof attributable to unreimbursed LC Disbursements)
during the period from and including the Effective Date to but excluding the later of the date of
termination of the Commitments and the date on which there ceases to be any LC Exposure, as well as
such Issuing Bank’s standard fees with respect to the issuance, amendment, renewal or extension of
any Letter of Credit or processing of drawings thereunder. Participation fees and fronting fees
accrued through and including the last day of March, June, September and December of each year
shall be payable on the third Business Day following such last day, commencing on the first such
date to occur after the Effective Date; provided that all such fees shall be payable on the date on
which the Commitments terminate and any such fees accruing after the date on which the Commitments
terminate shall be payable on demand. Any other fees payable to any Issuing Bank pursuant to this
paragraph shall be payable within 10 days after demand. All participation fees and fronting

28

 

fees shall be computed on the basis of a year of 360 days and shall be payable for the actual
number of days elapsed (including the first day but excluding the last day).

     (c) Borrower agrees to pay to the Administrative Agent, for its own account, fees payable in
the amounts and at the times separately agreed upon between Borrower and the Administrative Agent.

     (d) All fees payable hereunder shall be paid on the dates due, in immediately available funds,
to the Administrative Agent (or to any Issuing Bank, in the case of fees payable to it) for
distribution, in the case of Facility Fees and commissions pursuant to Section 2.11(b), to
the Lenders. Any and all fees paid shall not be refundable under any circumstances.

     SECTION 2.12 Interest.

     (a) The Loans comprising each ABR Borrowing shall bear interest on the daily amount
outstanding at the Alternate Base Rate plus the Base Rate Margin.

     (b) The Loans comprising each Eurodollar Borrowing shall bear interest on the daily amount
outstanding at the Adjusted LIBO Rate for the Interest Period in effect for such Borrowing plus the
Eurodollar Margin.

     (c) [Intentionally omitted].

     (d) Notwithstanding the foregoing, if any principal of or interest on any Loan or any fee or
other amount payable by Borrower hereunder is not paid when due, whether at stated maturity, upon
acceleration or otherwise, such overdue amount shall bear interest, after as well as before
judgment, at a rate per annum equal to (i) in the case of overdue principal of any Loan, 2% plus
the rate otherwise applicable to such Loan as provided in the preceding paragraphs of this Section
or (ii) in the case of any other amount, 2% plus the rate applicable to ABR Loans as provided in
paragraph (a) of this Section.

     (e) Accrued interest on each Loan shall be payable in arrears on each Interest Payment Date
for such Loan and, in the case of Loans on the Maturity Date; provided that (i) interest
accrued pursuant to paragraph (d) of this Section shall be payable on demand, (ii) in the event of
any repayment or prepayment of any Loan, accrued interest on the principal amount repaid or prepaid
shall be payable on the date of such repayment or prepayment, and (iii) in the event of any
conversion of any Eurodollar Loan prior to the end of the current Interest Period therefor, accrued
interest on such Loan shall be payable on the effective date of such conversion.

     (f) Subject to Section 10.12, all interest hereunder shall be computed on the basis of
a year of 360 days, except that interest computed by reference to the Alternate Base Rate at times
when the Alternate Base Rate is based on the Prime Rate shall be computed on the basis of a year of
365 days (or 366 days in a leap year), and in each case shall be payable for the actual number of
days elapsed (including the first day but excluding the last day). The applicable Alternate Base
Rate, Adjusted LIBO Rate or LIBO Rate shall be determined by the Administrative Agent, and such
determination shall be conclusive absent manifest error.

29

 

     SECTION 2.13 Alternate Rate of Interest. If prior to the commencement of any Interest Period for a
Eurodollar Borrowing:

     (a) the Administrative Agent determines (which determination shall be conclusive absent
manifest error) that adequate and reasonable means do not exist for ascertaining the Adjusted LIBO
Rate or the LIBO Rate, as applicable, for such Interest Period;

     (b) the Administrative Agent is advised by the Required Lenders that the Adjusted LIBO Rate
for such Interest Period will not adequately and fairly reflect the cost to such Lenders of making
or maintaining their Loans included in such Borrowing for such Interest Period; or

     (c) the Administrative Agent determines in good faith (which determination shall be conclusive
absent manifest error) that by reason of circumstances affecting the interbank dollar market
generally, deposits in dollars in the London interbank dollar market are not being offered for the
applicable Interest Period and in an amount equal to the amount of the Eurodollar Loan requested by
Borrower,

then the Administrative Agent shall give notice thereof to Borrower and the Lenders by telephone or
telecopy as promptly as practicable thereafter and, until the Administrative Agent notifies
Borrower and the Lenders that the circumstances giving rise to such notice no longer exist, (i) any
Interest Election Request that requests the conversion of any Borrowing to, or continuation of any
Borrowing as, a Eurodollar Borrowing for the affected Interest Period shall be ineffective, and
(ii) if any Borrowing Request requests a Eurodollar Borrowing, such Borrowing shall be made as a
Eurodollar Loan having the shortest Interest Period which is not unavailable under Section
2.13(a) through Section 2.13(c), and if no Interest Period is available, as an ABR
Borrowing.

     SECTION 2.14 Increased Costs.

     (a) If any Change in Law shall:

     (i) impose, modify or deem applicable any reserve, special deposit or similar
requirement against assets of, deposits with or for the account of, or credit extended by,
any Lender (except any such reserve requirement reflected in the Adjusted LIBO Rate) or any
Issuing Bank; or

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

and the result of any of the foregoing shall be to increase the cost to such Lender of making or
maintaining any Eurodollar Loan (or of maintaining its obligation to make any such Loan) or to
increase the cost to such Lender or such Issuing Bank of participating in, issuing or maintaining
any Letter of Credit or to reduce the amount of any sum received or receivable by such Lender or
such Issuing Bank hereunder (whether of principal, interest or otherwise), then Borrower will pay
to such Lender or such Issuing Bank, as the case may be, such additional amount or amounts
as will compensate such Lender or such Issuing Bank, as the case may be, for such additional costs
incurred or reduction suffered.

30

 

     (b) If any Lender or any Issuing Bank reasonably determines that any Change in Law regarding
capital requirements has or would have the effect of reducing the rate of return on such Lender’s
or such Issuing Bank’s capital or on the capital of such Lender’s or such Issuing Bank’s holding
company, if any, as a consequence of this Agreement or the Loans made by, or participations in
Letters of Credit held by, such Lender, or the Letters of Credit issued by such Issuing Bank, to a
level below that which such Lender or such Issuing Bank or such Lender’s or such Issuing Bank’s
holding company could have achieved but for such Change in Law (taking into consideration such
Lender’s or such Issuing Bank’s policies and the policies of such Lender’s or such Issuing Bank’s
holding company with respect to capital adequacy), then from time to time Borrower will pay to such
Lender or such Issuing Bank, as the case may be, such additional amount or amounts as will
compensate such Lender or such Issuing Bank or such Lender’s or such Issuing Bank’s holding company
for any such reduction suffered.

     (c) A certificate of a Lender or an Issuing Bank setting forth the amount or amounts necessary
to compensate such Lender or such Issuing Bank or its holding company, as the case may be, as
specified in paragraph (a) or (b) of this Section (together with the calculation thereof) shall be
delivered to Borrower and shall be conclusive absent demonstrable error. Borrower shall pay such
Lender or such Issuing Bank, as the case may be, the amount shown as due on any such certificate
within 10 days after receipt thereof.

     (d) Failure or delay on the part of any Lender or any Issuing Bank to demand compensation
pursuant to this Section shall not constitute a waiver of such Lender’s or such Issuing Bank’s
right to demand such compensation; provided that Borrower shall not be required to compensate a
Lender or an Issuing Bank pursuant to this Section for any increased costs or reductions incurred
more than 180 days prior to the date that such Lender or such Issuing Bank, as the case may be,
notifies Borrower of the Change in Law giving rise to such increased costs or reductions and of
such Lender’s or such Issuing Bank’s intention to claim compensation therefor; provided further
that, if the Change in Law giving rise to such increased costs or reductions is retroactive, then
the 180-day period referred to above shall be extended to include the period of retroactive effect
thereof.

     SECTION 2.15 Break Funding Payments. In the event of (a) the payment of any principal of any
Eurodollar Loan other than on the last day of an Interest Period applicable thereto (including as a
result of an Event of Default), (b) the conversion of any Eurodollar Loan other than on the last
day of the Interest Period applicable thereto, (c) the failure to borrow, convert, continue or
prepay any Loan on the date specified in any notice delivered pursuant hereto (regardless of
whether such notice may be revoked under Section 2.10(b) and is revoked in accordance
therewith), or (d) the assignment of any Eurodollar Loan other than on the last day of the Interest
Period applicable thereto as a result of a request by Borrower pursuant to Section 2.18
then, in any such event, Borrower shall compensate each Lender for the loss, cost and expense
attributable to such event. In the case of a Eurodollar Loan, such loss, cost or expense to any
Lender shall be deemed to include an amount determined by such Lender to be the excess, if any, of
(i) the amount of interest which would have accrued on the principal amount of such
Loan had such event not occurred, at the Adjusted LIBO Rate that would have been applicable to
such Loan, for the period from the date of such event to the last day of the then current Interest
Period therefor (or, in the case of a failure to borrow, convert or continue, for the period that
would have been the Interest Period for such Loan), over (ii) the amount of

31

 

interest which would
accrue on such principal amount for such period at the interest rate which such Lender would bid
were it to bid, at the commencement of such period, for dollar deposits of a comparable amount and
period from other banks in the eurodollar market. A certificate of any Lender setting forth any
amount or amounts that such Lender is entitled to receive, together with the calculation thereof,
pursuant to this Section shall be delivered to Borrower and to the Administrative Agent and shall
be conclusive absent demonstrable error. Borrower shall pay to the Administrative Agent for the
account of such Lender the amount shown as due on any such certificate within 10 days after receipt
thereof.

     SECTION 2.16 Taxes.

     (a) Any and all payments by or on account of any obligation of Borrower hereunder shall be
made free and clear of and without deduction for any Indemnified Taxes or Other Taxes; provided
that if Borrower shall be required to deduct any Indemnified Taxes or Other Taxes from such
payments, then (i) the sum payable shall be increased as necessary so that after making all
required deductions (including deductions applicable to additional sums payable under this Section)
the Administrative Agent, any Lender or any Issuing Bank (as the case may be) receives an amount
equal to the sum it would have received had no such deductions been made, (ii) Borrower shall make
such deductions and (iii) Borrower shall pay the full amount deducted to the relevant Governmental
Authority in accordance with applicable law.

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

     (c) Borrower shall pay the Administrative Agent, each Lender and each Issuing Bank, within 10
days after written demand therefor, the full amount of any Indemnified Taxes or Other Taxes paid by
the Administrative Agent, such Lender or such Issuing Bank, as the case may be, on or with respect
to any payment by or on account of any obligation of Borrower hereunder (including Indemnified
Taxes or Other Taxes imposed or asserted on or attributable to amounts payable under this Section)
and any penalties, interest and reasonable expenses arising therefrom or with respect thereto
(other than any such penalties or interest arising through the failure of the Administrative Agent
or Lender to act as a reasonably prudent agent or lender, respectively), whether or not such
Indemnified Taxes or Other Taxes were correctly or legally imposed or asserted by the relevant
Governmental Authority. A certificate as to the amount of such payment or liability delivered to
Borrower by a Lender or an Issuing Bank, or by the Administrative Agent on its own behalf or on
behalf of a Lender or an Issuing Bank, shall be conclusive absent demonstrable error.

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

     (e) Status of Lenders; Tax Documentation.

32

 

     (i) Each Lender that is a U.S. Person shall deliver to Borrower and the Administrative
Agent on or before the date on which it becomes a party to this Agreement two (2) duly
completed and executed originals of United States Internal Revenue Service Form W-9 (or any
successor form) certifying that such Lender is exempt from U.S. federal withholding tax.

     (ii) Each Foreign Lender agrees that such Lender will deliver to Borrower and the
Administrative Agent (or, in the case of a Participant, to the Lender from which the related
participation shall have been purchased) two (2) duly completed and executed originals of
United States Internal Revenue Service Form W-8 BEN, W-8 ECI and/or W-8 IMY (together with
any applicable underlying Internal Revenue Service withholding certificates that may be
required) certifying in each case that such Lender is entitled to receive payments from the
Borrower under the Loan Documents without deduction or withholding of any United States
federal income taxes. Such forms shall be delivered by each Foreign Lender on or before the
date it becomes a party to this Agreement (or, in the case of any Participant, on or before
the date such Participant purchases the related participation) and from time to time
thereafter upon the request of Borrower or the Administrative Agent. Each Lender which so
delivers a Form W-8 BEN, W-8 ECI or W-8 IMY further undertakes to deliver to Borrower and
the Administrative Agent two (2) additional executed originals of such form (or a successor
form) on or before such form expires or becomes obsolete or after the occurrence of any
event requiring a change in the most recent form so delivered by it and such amendments
thereto or extensions or renewals thereof as may be reasonably requested by Borrower or the
Administrative Agent, in each case, certifying that such Lender is entitled to receive
payments from Borrower under the Loan Documents without deduction or withholding of any
United States federal income taxes, unless (A) an event (including without limitation any
change in treaty, law or regulation) has occurred prior to the date on which any such
delivery would otherwise be required which renders all such forms inapplicable or which
would prevent such Lender from duly completing and delivering any such form with respect to
it and (B) such Lender advises Borrower and the Administrative Agent that it is not capable
of receiving such payments without any deduction or withholding of United States federal
income tax. Any Foreign Lender shall, to the extent it is legally entitled to do so, deliver
to Borrower and the Administrative Agent (in such number of copies as shall be requested by
the recipient) on or prior to the date on which such Foreign Lender becomes a Lender under
this Agreement (and from time to time thereafter upon the reasonable request of Borrower or
the Administrative Agent), executed originals of any other form prescribed by applicable law
as a basis for claiming exemption from or a reduction in United States federal withholding
Tax, duly completed, together with such supplementary documentation as may be prescribed by
applicable law to permit Borrower or the Administrative Agent to determine the withholding
or deduction required to be made.

     (iii) In addition to the applicable United States Internal Revenue Service Forms
required to be delivered pursuant to Section 2.16(e)(ii), each Foreign Lender
claiming the benefits of the exemption for portfolio interest under Section 881(c) of the
Code shall deliver a certificate to the effect that such Foreign Lender is not (A) a “bank”
within the meaning of Section 881(c)(3)(A) of the Code, (B) a “10 percent shareholder” of
the

33

 

Borrower within the meaning of Section 881(c)(3)(B) of the Code, or (C) a “controlled
foreign corporation” described in 
Section 881(c)(3)(C) of the Code.

     (iv) If a payment made to a Lender, the Administrative Agent or any Issuing Bank under
any Loan Document would be subject to United States federal withholding Tax imposed by FATCA
if such Lender, Administrative Agent or Issuing Bank were to fail to comply with the
applicable reporting requirements of FATCA (including those contained in Section 1471(b) or
1472(b) of the Code, as applicable), such Lender, Administrative Agent or Issuing Bank shall
deliver to Borrower and the Administrative Agent at the time or times prescribed by law and
at such time or times reasonably requested by Borrower or the Administrative Agent such
documentation prescribed by applicable law (including as prescribed by Section
1471(b)(3)(C)(i) of the Code) and such additional documentation reasonably requested by
Borrower or the Administrative Agent as may be necessary for Borrower and the Administrative
Agent to comply with their obligations under FATCA and to determine that such Lender,
Administrative Agent or Issuing Bank has complied with the obligations of such Lender,
Administrative Agent or Issuing Bank under FATCA or to determine the amount to deduct and
withhold from such payment. Solely for purposes of this Section 2.16(e)(iv),
“FATCA” shall include any amendments made to FATCA after the date of this Agreement.

     SECTION 2.17 Payments Generally; Pro Rata Treatment; Sharing of Set-offs.

     (a) Borrower shall make each payment required to be made by it to the Administrative Agent
hereunder (whether of principal, interest or fees, or of amounts payable under Sections
2.14, 2.15 or 2.16, or otherwise) prior to 1:00 p.m., New York City time, and,
with respect to reimbursement of LC Disbursements, prior to 2:00 p.m., New York City time, in each
case, on the date when due, in immediately available funds, without set-off or counterclaim. All
such payments shall be made to the Administrative Agent, c/o Loan & Agency Services Group, JPMorgan
Chase Bank, N.A., 1111 Fannin Street, 10th Floor, Houston, Texas 77002-8069, Attention:
Bejaye E. Ilegbodu, telephone no.: 713-750-4147, facsimile no.: 713-427-6307, except payments to be
made directly to any Issuing Bank as expressly provided herein and except that payments pursuant to
Sections 2.14, 2.16 and 10.3 shall be made directly to the Persons entitled
thereto. The Administrative Agent shall distribute any such payments received by it for the
account of any other Person to the appropriate recipient promptly following receipt thereof. If
any payment hereunder shall be due on a day that is not a Business Day, the date for payment shall
be extended to the next succeeding Business Day, and, in the case of any payment accruing interest,
interest thereon shall be payable for the period of such extension. All payments hereunder shall
be made in dollars.

     (b) If at any time insufficient funds are received by and available to the Administrative
Agent to pay fully all amounts of principal, unreimbursed LC Disbursements,
interest and fees then due hereunder, such funds shall be applied (i) first, towards payment
of interest and fees then due hereunder, ratably among the parties entitled thereto in accordance
with the amounts of interest and fees then due to such parties, and (ii) second, towards payment of
principal and unreimbursed LC Disbursements then due hereunder, ratably among the parties entitled
thereto in accordance with the amounts of principal and unreimbursed LC Disbursements then due to
such parties. If insufficient funds are received due to Borrower’s entitlement to

34

 

withhold amounts
on account of Excluded Taxes in relation to a particular Lender, such insufficiency shall not be
subject to this
 Section 2.17(b) but shall be withheld from and shall only affect payments
made to such Lender.

     (c) If any Lender shall, by exercising any right of set-off or counterclaim or otherwise,
obtain payment in respect of any principal of or interest on any of its Loans or participations in
LC Disbursements resulting in such Lender receiving payment of a greater proportion of the
aggregate amount of its Loans and participations in LC Disbursements and accrued interest thereon
than the proportion received by any other Lender, then the Lender receiving such greater proportion
shall purchase (for cash at face value) participations in the Loans and participations in the LC
Disbursements of other Lenders to the extent necessary so that the benefit of all such payments
shall be shared by the Lenders ratably in accordance with the aggregate amount of principal of and
accrued interest on their respective Loans and participations in LC Disbursements; provided that
(i) if any such participations are purchased and all or any portion of the payment giving rise
thereto is recovered, such participations shall be rescinded and the purchase price restored to the
extent of such recovery, without interest, and (ii) the provisions of this paragraph shall not be
construed to apply to any payment made by Borrower pursuant to and in accordance with the express
terms of this Agreement or any payment obtained by a Lender as consideration for the assignment of
or sale of a participation in any of its Loans or participations in LC Disbursements to any
assignee or participant, other than to Borrower or any Subsidiary or Affiliate thereof (as to which
the provisions of this paragraph shall apply). Borrower consents to the foregoing and agrees, to
the extent (x) Borrower may effectively do so under applicable law and (y) any Lender may
effectively do so pursuant to Section 10.8, that any Lender acquiring a participation
pursuant to the foregoing arrangements may exercise against Borrower rights of set-off and
counterclaim with respect to such participation as fully as if such Lender were a direct creditor
of Borrower in the amount of such participation.

     (d) Unless the Administrative Agent shall have received notice from Borrower prior to the date
on which any payment is due to the Administrative Agent for the account of the Lenders or any
Issuing Bank hereunder that Borrower will not make such payment, the Administrative Agent may
assume that Borrower has made such payment on such date in accordance herewith and may, in reliance
upon such assumption, distribute to the Lenders or any Issuing Bank, as the case may be, the amount
due. In such event, if Borrower has not in fact made such payment, then each of the Lenders or any
Issuing Bank, as the case may be, severally agrees to repay to the Administrative Agent forthwith
on demand the amount so distributed to such Lender or such Issuing Bank with interest thereon, for
each day from and including the date such amount is distributed to it to but excluding the date of
payment to the Administrative Agent, at the greater of the Federal Funds Effective Rate and a rate
determined by the Administrative Agent in accordance with banking industry rules on interbank
compensation.

     (e) If any Lender shall fail to make any payment required to be made by it pursuant to
Section 2.17(d), then the Administrative Agent may, in its discretion, notwithstanding any
contrary provision hereof, (i) apply any amounts thereafter received by the Administrative Agent
for the account of such Lender for the benefit of the Administrative Agent to satisfy such Lender’s
obligations to it under such Section until all such unsatisfied obligations are fully paid, and/or
(ii) hold any such amounts in a segregated account as cash collateral for, and application

35

 

to, any
future funding obligations of such Lender under any such Section, in the case of each of clauses
(i) and (ii) above, in any order as determined by the Administrative Agent in its reasonable
discretion.

     SECTION 2.18 Mitigation Obligations; Replacement of Lenders.

     (a) If any Lender requests compensation under Section 2.14, or if Borrower is required
to pay any additional amount to any Lender or any Governmental Authority for the account of any
Lender pursuant to Section 2.16, then such Lender shall use reasonable efforts to designate
a different lending office for funding or booking its Loans hereunder or to assign its rights and
obligations hereunder to another of its offices, branches or affiliates, if, in the judgment of
such Lender, such designation or assignment (i) would eliminate or reduce amounts payable pursuant
to Section 2.14 or 2.16, as the case may be, in the future and (ii) would not
subject such Lender to any unreimbursed cost or expense and would not otherwise be disadvantageous
to such Lender. Borrower hereby agrees to pay all reasonable costs and expenses incurred by any
Lender in connection with any such designation or assignment.

     (b) If any Lender requests compensation under Section 2.14, or if Borrower is required
to pay any additional amount to any Lender or any Governmental Authority for the account of any
Lender pursuant to Section 2.16, or if any Lender defaults in its obligation to fund Loans
hereunder, or if any Lender is a Defaulting Lender hereunder, then Borrower may upon notice to such
Lender and the Administrative Agent, require such Lender to assign and delegate, without recourse
or expense to, or warranty by, such Lender (in accordance with and subject to the restrictions
contained in Section 10.4), all its interests, rights and obligations under this Agreement
to an assignee designated by Borrower which meets the requirements of Section 10.4(b) that
shall assume such obligations (which assignee may be another Lender, if a Lender accepts such
assignment); provided that (i) Borrower shall have received the prior written consent of the
Administrative Agent (and if participations in Letters of Credit are being assigned, the applicable
Issuing Banks), which consent shall not unreasonably be withheld or delayed, (ii) such Lender shall
have received payment of an amount equal to the outstanding principal of its Loans and
participations in LC Disbursements, accrued interest thereon, accrued fees and all other amounts
payable to it hereunder, from the assignee (to the extent of such outstanding principal and accrued
interest and fees) or Borrower (in the case of all other amounts), (iii) the assignee and assignor
shall have entered into an Assignment and Acceptance, and (iv) in the case of any such assignment
resulting from a claim for compensation under Section 2.14 or payments required to be made
pursuant to Section 2.16, such assignment will result in a reduction in such compensation
or payments.

     SECTION 2.19 Defaulting Lenders. Notwithstanding any provision of this Agreement to the contrary,
if any Lender becomes a Defaulting Lender, then the following provisions shall apply for so long as
such Lender is a Defaulting Lender:

     (a) Fees shall cease to accrue on the Commitment of such Defaulting Lender pursuant to
Section 2.11.

     (b) the Commitment and Credit Exposure of such Defaulting Lender shall not be included (in
either the calculation of aggregate Commitments, outstanding Obligations or

36

 

otherwise) in
determining whether the Required Lenders have taken or may take any action hereunder (including any
consent to any amendment, waiver or other modification pursuant to Section 10.2);
provided, that this clause (b) shall not apply to the vote of a Defaulting Lender in the
case of an amendment, waiver or other modification requiring the consent of such Lender as a Lender
affected thereby pursuant to Section 10.2(b).

     (c) if any LC Exposure exists at the time a Lender becomes a Defaulting Lender then:

     (i) all or any part of such LC Exposure shall be reallocated among the Non-Defaulting
Lenders in accordance with their respective Applicable Percentages (for the purposes of such
reallocation the Defaulting Lender’s Commitment shall be disregarded in determining the
Non-Defaulting Lender’s Applicable Percentage) but only to the extent (x) the sum of all
Non-Defaulting Lenders’ Credit Exposures plus such Defaulting Lender’s LC Exposure does not
exceed the total of all Non-Defaulting Lenders’ Commitments and (y) the sum of each
Non-Defaulting Lender’s Credit Exposure plus its reallocated share of such Defaulting
Lender’s LC Exposure does not exceed such Non-Defaulting Lender’s Commitment;

     (ii) if the LC Exposure of the Non-Defaulting Lenders is reallocated pursuant to
Section 2.19, then the fees payable to the Lenders pursuant to Section 2.11
shall be adjusted in accordance with such Non-Defaulting Lenders’ Applicable Percentages;
and

     (iii) if any Defaulting Lender’s LC Exposure is not reallocated pursuant to Section
2.19(c), then, without prejudice to any rights or remedies of any Issuing Bank or any
Lender hereunder, all commitment fees that otherwise would have been payable to such
Defaulting Lender (solely with respect to the portion of such Defaulting Lender’s Commitment
that was utilized by such LC Exposure) and letter of credit fees payable under Section
2.11(b) with respect to such Defaulting Lender’s LC Exposure shall be payable to the
applicable Issuing Bank until such LC Exposure is reallocated.

     (d) so long as any Lender is a Defaulting Lender, no Issuing Bank shall be required to issue,
extend or increase any Letter of Credit, unless it is satisfied that the related exposure will be
100% covered by the Commitments of the Non-Defaulting Lenders, and participating interests in any
such newly issued or increased Letter of Credit shall be allocated among Non-Defaulting Lenders in
a manner consistent with 
Section
2.4(d) (and Defaulting Lenders shall not participate
therein).

     (e) Borrower may elect to replace any Defaulting Lender in accordance with the provisions of
Section 2.18(b). In the event that the Administrative Agent, the Borrower and the Issuing
Bank each agrees that a Defaulting Lender has adequately remedied all matters that caused such
Lender to be a Defaulting Lender, then the Credit Exposure of the Lenders shall be readjusted to
reflect the inclusion of such Lender’s Commitment and on such date, if necessary as a result of a
Loan funding pursuant to Section 2.4(h), such Lender shall purchase at par such of the
Loans of the other Lenders as the Administrative Agent shall determine may be necessary in order
for such Lender to hold such Loans in accordance with its Applicable Percentage.

ARTICLE III

Representations and Warranties

     In order to induce the Lenders and the Agents to enter into this Agreement and the Lenders to
make Loans hereunder, Borrower represents and warrants unto the Agents and each Lender as set forth
in this Article III.

     SECTION 3.1 Organization. Borrower is a corporation, and each of its Subsidiaries is a
corporation or other legal entity, in either case duly incorporated or otherwise properly
organized, validly existing and in good standing under the laws of its jurisdiction of
incorporation or organization and has all requisite authority, permits and approvals, and is in
good standing to conduct its business in each jurisdiction in which its business is conducted where
the failure to so qualify would have a Material Adverse Effect.

     SECTION 3.2 Authorization and Validity. The execution, delivery and performance by Borrower of
this Agreement and each other Loan Document executed or to be executed by it, are within Borrower’s
corporate powers, have been duly authorized by all necessary corporate action on behalf of it, and
do not (a) contravene Borrower’s articles of incorporation or other organizational documents, as
the case may be; (b) contravene any material contractual restriction, law or governmental
regulation or court decree or order binding on or affecting Borrower or any Subsidiary; or (c)
result in, or require the creation or imposition of, any Lien, not permitted by Section
7.1, on any of Borrower’s or any Subsidiary’s properties. This Agreement constitutes, and each
other Loan Document executed by Borrower will, on the due execution and delivery thereof,
constitute, the legal, valid and binding obligations of Borrower enforceable in accordance with
their respective terms subject as to enforcement only to bankruptcy, insolvency, reorganization,
moratorium or other similar laws affecting the enforcement of creditor rights generally and to
general principles of equity.

     SECTION 3.3 Government Approval and Regulation. No authorization or approval or other action by,
and no notice to or filing with, any governmental authority or regulatory body or other Person is
required for the due execution, delivery or performance by Borrower of this Agreement or any other
Loan Document. Neither Borrower nor any of its Subsidiaries is an “investment company,” within the
meaning of the Investment Company Act of 1940, as amended.

     SECTION 3.4 Pension and Welfare Plans. During the twelve-consecutive-month period prior to the
date of the execution and delivery of this Agreement and prior to the date of
any Borrowing hereunder, no steps have been taken to terminate any Pension Plan, and no
contribution failure has occurred with respect to any Pension Plan sufficient to give rise to a
lien under Section 302(f) of ERISA. No condition exists or event or transaction has occurred with
respect to any Pension Plan which would result in the incurrence by Borrower or any member of the
Controlled Group of any liability, fine or penalty in excess of $100,000,000. Neither Borrower nor
any member of the Controlled Group has any contingent liability with respect to any post-retirement
benefit under a Welfare Plan, other than liability for continuation coverage described in Part 6 of
Title I of ERISA.

38

 

     SECTION 3.5 Regulation U. Borrower is not engaged in the business of extending credit for the
purpose of purchasing or carrying margin stock, and no proceeds of any Loans will be used for a
purpose which violates, or would be inconsistent with, Regulation U. Terms for which meanings are
provided in Regulations U are used in this Section with such meanings.

     SECTION 3.6 Taxes. Borrower and each of its Subsidiaries has to the best knowledge of Borrower
after due investigation filed all tax returns and reports required by law to have been filed by it
and has paid all taxes and governmental charges thereby shown to be owing, except any such taxes or
charges which are being contested in good faith by appropriate proceedings and for which adequate
reserves in accordance with GAAP shall have been set aside on its books or which the failure to
file or pay could not reasonably be expected to have a Material Adverse Effect.

     SECTION 3.7 Subsidiaries; Restricted Subsidiaries. Schedule 3.7 hereto contains an accurate list of
all of the presently existing Subsidiaries, including, without limitation, Restricted Subsidiaries,
of Borrower as of the date of this Agreement, setting forth their respective jurisdictions of
incorporation or organization and the percentage of their respective capital stock or, the revenue
share attributable to the general and limited partnership interests, as the case may be, owned by
Borrower or other Subsidiaries. All of the issued and outstanding shares of capital stock of such
Subsidiaries which are corporations have been duly authorized and issued and are fully paid and
non-assessable.

Effective Date no material adverse change in the condition or operations of Borrower and its
Subsidiaries, taken as a whole, from that reflected in the 2010 Financials has occurred and is
continuing.

     (e) Environmental Warranties. In the ordinary course of its business, Borrower
conducts an ongoing review of the effect of existing Environmental Laws on the business, operations

evaluate associated liabilities and costs (including, without limitation, any capital or operating
expenditures required for clean-up or closure of properties presently or previously owned, any
capital or operating expenditures required to achieve or maintain compliance with environmental
protection standards imposed by law or as a condition of any license, permit or contract, any
related constraints on operating activities, including any periodic or permanent shutdown of any
facility or reduction in the level of or change in the nature of operations conducted thereat and
any actual or potential liabilities to third parties, including employees, and any related costs
and expenses). On the basis of this review, the Administrative Agent shall have received a
certificate, signed by an Authorized Officer of Borrower, stating that after such review Borrower
has reasonably concluded that existing Environmental Laws are unlikely to have a Material Adverse
Effect, or that Borrower has established adequate reserves in respect of any required clean-up or
other remediation.

     (f) Effectiveness Notice. The Administrative Agent shall have received the
Effectiveness Notice.

     (g) Litigation. The Administrative Agent shall have received a certificate, signed by

validity or enforceability of this Agreement or any other Loan Document.

     (h) Existing Credit Facility. The Administrative Agent shall have received a
certificate, executed by an Authorized Officer of the Borrower, stating that either (i) Borrower

The Administrative Agent shall notify Borrower, the other Agents and the Lenders of the Effective
Date, and such notice shall be conclusive and binding. Notwithstanding the foregoing, the
obligations of the Lenders to make Loans and of the Issuing Banks to issue Letters of Credit
hereunder shall not become effective unless each of the foregoing conditions is satisfied (or
waived pursuant to Section 10.2) at or prior to 3:00 p.m., New York City time, on August
31,

40

 

2011 (and, in the event such conditions are not so satisfied or waived, the Commitments shall
terminate at such time).

     SECTION 4.2 All Loans. The obligation of each Lender to fund any Loan which results in an
increase in the aggregate outstanding principal amount of Loans under this Agreement on the
occasion of any Borrowing, and of the Issuing Banks to issue, amend, renew or extend any Letter of
Credit, shall be subject to the satisfaction of each of the conditions precedent set forth in this
Section 4.2.

any Borrowing or issuance, amendment, renewal or extension of any Letter of Credit, the following
statements shall be true and correct: (1) the representations and warranties set forth in
Article III shall be true and correct with the same effect as if then made (unless stated
to relate solely to an earlier date, in which case such representations and warranties shall be
true and correct as of such earlier date); and (2) no Default or Event of Default shall have then
occurred and be continuing.

     (b) Borrowings. The Administrative Agent shall have received a Borrowing Request for
such Borrowing.

ARTICLE V

Affirmative Covenants

     Until the Commitments have expired or been terminated, all Obligations shall have been paid in
full and all Letters of Credit shall have expired or terminated and all LC Disbursements shall have
been reimbursed, and unless the Required Lenders shall otherwise consent in writing, Borrower
covenants and agrees with the Lenders that:

     SECTION 5.1 Financial Reporting and Notices. Borrower will furnish, or will cause to be
furnished, to each Lender and the Administrative Agent copies of the following financial
statements, reports, notices and information:

	 	(a)	 	within 90 days after the end of each Fiscal Year of Borrower, a copy of the
audited annual report for such fiscal year for Borrower and its Subsidiaries, including
therein consolidated balance sheets of Borrower and its Subsidiaries as of the end of
such fiscal year and consolidated statements of earnings and cash
flow of Borrower and its Subsidiaries for such fiscal year, in each case certified
(without qualification) by independent public accountants of nationally recognized

property or assets of the Borrower and its Subsidiaries if the aggregate Indebtedness
of all such Persons secured thereby does not exceed five percent (5%) of Borrower’s
Consolidated Assets; provided that nothing in this definition shall in and of itself
constitute or be deemed to constitute an agreement or acknowledgment by the
Administrative Agent or any Lender that the Indebtedness subject to or secured by any
such Lien ranks (apart from the effect of any Lien included in or inherent in any such
Liens) in priority to the Obligations.

     SECTION 7.2 Mergers. Borrower will not liquidate or dissolve, consolidate with, or merge into or
with, any other Person, or sell, lease or otherwise transfer all or substantially all of its assets
unless (a) Borrower is the survivor of such merger or consolidation, and (b) no Default or Event of
Default has occurred and is continuing or would occur after giving effect thereto.

Borrower to another Subsidiary of such Borrower.

limiting the ability of Borrower to amend or otherwise modify this Agreement or any other Loan
Document. Borrower will not, and will not permit any of its Restricted Subsidiaries to, enter into
any agreement which restricts or prohibits the ability of any Restricted Subsidiary to make any
payments, directly or indirectly, to Borrower by way of dividends, advances, repayments of loans or
advances, reimbursements of management and other intercompany charges, expenses and accruals or
other returns on investments, or any other agreement or arrangement which restricts the ability of
any such Restricted Subsidiary to make any payment, directly or indirectly, to Borrower.

45

the Commitments shall terminate. Without limiting the foregoing, the Administrative Agent and the
Lenders shall be entitled to exercise any and all other remedies available to them under the Loan

ARTICLE IX

Agents

     Each of the Lenders and each of the Issuing Banks hereby irrevocably appoints JPMorgan as
Administrative Agent, and Citibank, N.A., Bank of America, N.A. and Wells Fargo Bank, National
Association as Syndication Agents and authorizes each such Agent to take such actions on its behalf
and to exercise such powers as are delegated to such Agent by the terms hereof, together with such
actions and powers as are reasonably incidental thereto.

     Any bank serving as an Agent hereunder shall have the same rights and powers in its capacity
as a Lender as any other Lender and may exercise the same as though it were not an Agent, and such
bank and its Affiliates may accept deposits from, lend money to and generally
engage in any kind of business with Borrower or any Subsidiary or other Affiliate thereof as
if it were not an Agent hereunder.

     The Agents shall not have any duties or obligations except those expressly set forth herein.
Without limiting the generality of the foregoing, (a) the Agents shall not be subject to any
fiduciary or other implied duties, regardless of whether a Default has occurred and is continuing,
(b) each Agent shall not have any duty to take any discretionary action or exercise any
discretionary powers, except discretionary rights and powers expressly contemplated hereby that
such Agent is required to exercise in writing by the Required Lenders (or such other number or
percentage of the Lenders as shall be necessary under the circumstances as provided in Section
10.2), and (c) except as expressly set forth herein, each Agent shall not have any duty to
disclose, and shall not be liable for the failure to disclose, any information relating to Borrower
or any of its Subsidiaries that is communicated to or obtained by the bank serving as such Agent or
any of its Affiliates in any capacity. Each Agent shall not be liable for any action taken or not
taken by it with the consent or at the request of the Required Lenders (or such other number or
percentage of the Lenders as shall be necessary under the circumstances as provided in Section
10.2) or in the absence of its own gross negligence or willful misconduct. Each Agent shall be
deemed not to have knowledge of any Default unless and until written notice thereof is given to
such Agent by Borrower or a Lender, and such Agent shall not be responsible for or have any duty to
ascertain or inquire into (i) any statement, warranty or representation made in or in

48

 

connection
with this Agreement, (ii) the contents of any certificate, report or other document delivered
hereunder or in connection herewith, (iii) the performance or observance of any of the covenants,
agreements or other terms or conditions set forth herein, (iv) the validity, enforceability,
effectiveness or genuineness of this Agreement or any other agreement, instrument or document, or
(v) the satisfaction of any condition set forth in Article IV or elsewhere herein, other
than to confirm receipt of items expressly required to be delivered to such Agent. None of the
Persons identified on the facing page of this Agreement as the “Joint Lead Arrangers and Joint
Bookrunners” (the “Arrangers”) or the Syndication Agents shall have any right, power,
obligation, liability, responsibility or duty under this Agreement or any other Loan Document other
than, except in the case of the Arrangers, those applicable to all Lenders as such.

     The Administrative Agent and the other Agents shall be entitled to rely upon, and shall not
incur any liability for relying upon, any notice, request, certificate, consent, statement,
instrument, document or other writing believed by it to be genuine and to have been signed or sent
by the proper Person. The Administrative Agent and the other Agents also may rely upon any
statement made to it orally or by telephone and believed by it to be made by the proper Person, and
shall not incur any liability for relying thereon. The Administrative Agent and the other Agents
may consult with legal counsel (who may be counsel for Borrower), independent accountants and other
experts selected by it, and shall not be liable for any action taken or not taken by it in
accordance with the advice of any such counsel, accountants or experts.

     Any Agent may perform any and all of its duties and exercise its rights and powers by or
through any one or more sub-agents appointed by such Agent. Any Agent and any such sub-agent may
perform any and all of its duties and exercise its rights and powers through their respective
Related Parties. The exculpatory provisions of the preceding paragraphs shall apply
to any such sub-agent and to the Related Parties of such Agent and any such sub-agent, and
shall apply to their respective activities in connection with the syndication of the credit
facilities provided for herein as well as activities as an Agent.

     Subject to the appointment and acceptance of a successor Administrative Agent as provided in
this paragraph, the Administrative Agent may resign at any time by notifying the Lenders, the
Issuing Banks and Borrower. Upon any such resignation, Borrower shall have the right, in
consultation with the Required Lenders, to appoint one of the Lenders as a successor. If no
successor shall have been so appointed by Borrower and shall have accepted such appointment within
30 days after the retiring Administrative Agent gives notice of its resignation, then the retiring
Administrative Agent may, on behalf of the Lenders and the Issuing Banks, appoint a successor
Administrative Agent which shall be a bank with an office in New York, New York, or an Affiliate of
any such bank. Upon the acceptance of its appointment as Administrative Agent hereunder by a
successor, such successor shall succeed to and become vested with all the rights, powers,
privileges and duties of the retiring Administrative Agent, and the retiring Administrative Agent
shall be discharged from its duties and obligations hereunder. The fees payable by Borrower to a
successor Administrative Agent shall be the same as those payable to its predecessor unless
otherwise agreed between Borrower and such successor. After the Administrative Agent’s resignation
hereunder, the provisions of this Article and Section 10.3 shall continue in effect for the
benefit of such retiring Administrative Agent, its sub-agents and

49

 

their respective Related Parties
in respect of any actions taken or omitted to be taken by any of them while it was acting as
Administrative Agent.

     Each Lender acknowledges that it has, independently and without reliance upon any Agent or any
other Lender and based on such documents and information as it has deemed appropriate, made its own
credit analysis and decision to enter into this Agreement. Each Lender also acknowledges that it
will, independently and without reliance upon any Agent or any other Lender and based on such
documents and information as it shall from time to time deem appropriate, continue to make its own
decisions in taking or not taking action under or based upon this Agreement, any related agreement
or any document furnished hereunder or thereunder.

     SECTION 10.2 Waivers; Amendments.

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

     (b) Neither this Agreement nor any other Loan Document nor any provision hereof or thereof may
be waived, amended or modified except pursuant to an agreement or agreements in writing entered
into by Borrower and the Required Lenders or by Borrower and the Administrative Agent with the
consent of the Required Lenders; provided that no such agreement shall (i) increase the Commitment
of any Lender or the Commitments without the written consent of such Lender or each Lender,
respectively, (ii) reduce the principal amount of any Loan or LC Disbursement or reduce the rate of
interest thereon, or reduce any fees payable hereunder, without the written consent of each Lender
affected thereby, (iii) postpone the scheduled date of payment of the principal amount of any Loan
or LC Disbursement, or any interest thereon, or any fees payable hereunder, or reduce the amount
of, waive or excuse any such payment, or postpone the scheduled date of expiration of any
Commitment, without the written consent of each Lender affected thereby, (iv) change Sections
2.17(b) or (c) in a manner that would alter the pro rata sharing of payments required
thereby, without the written consent of each Lender, or (v) change any of the provisions of this
Section or the definition of “Required Lenders” or any other provision hereof or thereof
specifying the number or percentage of Lenders required to waive, amend or modify any rights
hereunder or thereunder or make any determination or grant any consent hereunder or thereunder,
without the written consent of each Lender; provided further that no such agreement shall amend,
modify or otherwise affect the rights or duties of the Administrative Agent or the Issuing Banks
hereunder or thereunder without the prior written consent of the Administrative Agent or the
applicable Issuing Banks, as the case may be.

     SECTION 10.3 Expenses; Indemnity; Damage Waiver.

     (a) Borrower shall pay (i) all reasonable out-of-pocket expenses incurred by J.P. Morgan
Securities LLC and the Agents, including the reasonable fees, charges and disbursements of counsel
for the Agents, in connection with the syndication of the credit facilities provided for herein,
the preparation, execution, delivery and administration of this Agreement or any amendments,
modifications or waivers of the provisions hereof (whether or not the transactions contemplated
hereby or thereby shall be consummated), (ii) all reasonable out-of-pocket expenses incurred by any
Issuing Bank in connection with the issuance, amendment, renewal or extension of any Letter of
Credit or any demand for payment thereunder and (iii) all reasonable out-of-pocket expenses
incurred by the Agents, any Issuing Bank or any Lender, including the reasonable fees, charges and
disbursements of any counsel for the Agents, any Issuing Bank or any Lender, in connection with the
enforcement or protection of its rights in connection with this Agreement, including its rights
under this Section, or in connection with the Loans made or Letters of Credit issued hereunder,
including all such out-of-pocket expenses incurred during any workout, restructuring or
negotiations in respect of such Loans, Letters of Credit or this Agreement.

     (b) Borrower shall indemnify the Agents, the Arrangers, each Issuing Bank and each Lender, and
each Related Party of any of the foregoing Persons (each such Person being called an
“Indemnitee”), WHETHER OR NOT RELATED TO ANY NEGLIGENCE OF THE
INDEMNITEE, against, and hold each Indemnitee harmless from, any and all losses, claims,
damages, liabilities and related expenses, including the reasonable fees, charges and disbursements
of any counsel for any Indemnitee, incurred by or asserted against any Indemnitee arising out of,
in connection with, or as a result of (i) the execution or delivery of this Agreement or any
agreement or instrument contemplated hereby, the performance by the parties hereto of their
respective obligations hereunder or the consummation of the Transactions or any other transactions
contemplated hereby, (ii) any Loan or Letter of Credit or the actual or proposed use of the
proceeds therefrom (including any refusal by any Issuing Bank to honor a demand for payment under a
Letter of Credit if the documents presented in connection with such demand do not strictly comply
with the terms of such Letter of Credit, (iii) any actual or alleged presence or release of
Hazardous Materials on or from any property owned or operated by Borrower or any of its
Subsidiaries, or any Environmental Liability related in any way to Borrower or any of its
Subsidiaries, or (iv) any actual or prospective claim, litigation, investigation or proceeding
relating to any of the foregoing, whether based on contract, tort or any other theory and
regardless of whether brought by a third party or by the Borrower and regardless of whether any
Indemnitee is a party thereto; provided that such indemnity shall not, as to any Indemnitee, be
available to the extent that such losses, claims, damages, liabilities or related expenses (i)
resulted from the gross negligence or willful misconduct of such Indemnitee or (ii) arise in
connection with any issue in litigation commenced by Borrower or any of its Subsidiaries against
any Indemnitee for which a final judgment is entered in favor of Borrower or any of its
Subsidiaries against such Indemnitee.

     (c) To the extent that Borrower fails to pay any amount required to be paid by it to the
Administrative Agent or any Issuing Bank under paragraph (a) or (b) of this Section, each Lender
severally agrees to pay to the Administrative Agent or any Issuing Bank, as the case may be, such
Lender’s Applicable Percentage (determined as of the time that the applicable

53

 

unreimbursed expense or indemnity payment is sought) of such unpaid amount; provided that the unreimbursed expense or
indemnified loss, claim, damage, liability or related expense, as the case may be, was incurred by
or asserted against the Administrative Agent or any Issuing Bank, in its capacity as such.

     (d) To the extent permitted by applicable law, (i) Borrower shall not assert, and hereby
waives, any claim against any Indemnitee, and (ii) Agents and Lenders shall not assert, and hereby
waives, any claim against any Borrower, in each case on any theory of liability, for special,
indirect, consequential or punitive damages (as opposed to direct or actual damages) arising out
of, in connection with, or as a result of, this Agreement or any agreement or instrument
contemplated hereby, the Transactions or any Loan or the use of the proceeds thereof, except for
any such claim arising from the gross negligence or willful misconduct of such Indemnitee or the
Borrower, as applicable; provided that, notwithstanding the foregoing, nothing contained in
this sentence shall limit the Borrower’s indemnity obligations with respect to claims asserted by
Persons (other than the Agents and the Lenders) to the extent set forth in this Section
10.3.

     (e) All amounts due under this Section shall be payable not later than thirty (30) days after
written demand therefor.

     SECTION 10.4 Successors and Assigns.

     (a) The provisions of this Agreement shall be binding upon and inure to the benefit of the
parties hereto and their respective successors and assigns permitted hereby (including any
Affiliate of any Issuing Bank that issues any Letter of Credit), except that Borrower may not
assign or otherwise transfer any of its rights or obligations hereunder without the prior written
consent of each Lender (and any attempted assignment or transfer by Borrower without such consent
shall be null and void). Nothing in this Agreement, expressed or implied, shall be construed to
confer upon any Person (other than the parties hereto, their respective successors and assigns
permitted hereby (including any Affiliate of any Issuing Bank that issues any Letter of Credit)
and, to the extent expressly contemplated hereby, the Related Parties of each of the Administrative
Agent, the Issuing Banks and the Lenders) any legal or equitable right, remedy or claim under or by
reason of this Agreement.

     (b) Any Lender may assign to one or more assignees all or a portion of its rights and
obligations under this Agreement (including all or a portion of its Commitment and the Loans at the
time owing to it); provided that (i) Borrower must give its prior written consent to such
assignment (which consent shall not be unreasonably withheld or delayed); (ii) except in the case
of an assignment to a Lender or an Affiliate of a Lender, the Administrative Agent and the
applicable Issuing Banks must give its prior written consent to such assignment (which consent
shall not be unreasonably withheld or delayed), (iii) except in the case of an assignment to a
Lender or an assignment of the entire remaining amount of the assigning Lender’s Commitment, the
amount of the Commitment of the assigning Lender subject to each such assignment (determined as of
the date the Assignment and Acceptance with respect to such assignment is delivered to the
Administrative Agent) shall be in increments of $1,000,000 and not less than $10,000,000 unless
each of Borrower and the Administrative Agent otherwise consent, (iv) each partial assignment shall
be made as an assignment of a proportionate part of all the assigning

54

 

Lender’s rights and obligations under this Agreement, (v) the parties to each assignment shall execute and deliver to
the Administrative Agent an Assignment and Acceptance, together with a processing and recordation
fee of $3,500, and (vi) the assignee, if it shall not be a Lender, shall deliver to the
Administrative Agent an Administrative Questionnaire; and provided further that any consent of
Borrower otherwise required under this paragraph shall not be required if an Event of Default under
Section 8.1 has occurred and is continuing. Subject to acceptance and recording thereof
pursuant to paragraph (d) of this Section, from and after the effective date specified in each
Assignment and Acceptance the assignee thereunder shall be a party hereto and, to the extent of the
interest assigned by such Assignment and Acceptance, have the rights and obligations of a Lender
under this Agreement, and the assigning Lender thereunder shall, to the extent of the interest
assigned by such Assignment and Acceptance, be released from its obligations under this Agreement
(and, in the case of an Assignment and Acceptance covering all of the assigning Lender’s rights and
obligations under this Agreement, such Lender shall cease to be a party hereto but shall continue
to be entitled to the benefits of Sections 2.14, 2.15, 2.16, 2.17
and 10.3). Any assignment or transfer by a Lender of rights or obligations under this
Agreement that does not comply with this paragraph shall be treated for purposes of this Agreement
as a sale by such Lender of a participation in such rights and obligations in accordance with
paragraph (e) of this Section.

     (c) The Administrative Agent, acting for this purpose as an agent of Borrower, shall maintain
at one of its offices in The City of New York a copy of each Assignment and Acceptance delivered to
it and a register for the recordation of the names and addresses of the Lenders, and the Commitment
of, and principal amount of the Loans and LC Disbursements owing to, each Lender pursuant to the
terms hereof from time to time (the “Register”). The entries in the Register shall be
conclusive, and Borrower, the Administrative Agent, the Issuing Banks and the Lenders may treat
each Person whose name is recorded in the Register pursuant to the terms hereof as a Lender
hereunder for all purposes of this Agreement, notwithstanding notice to the contrary. The Register
shall be available for inspection by Borrower, any Issuing Bank and any Lender, at any reasonable
time and from time to time upon reasonable prior notice.

     (d) Upon its receipt of a duly completed Assignment and Acceptance executed by an assigning
Lender and an assignee, the assignee’s completed Administrative Questionnaire (unless the assignee
shall already be a Lender hereunder), the processing and recordation fee referred to in paragraph
(b) of this Section and any written consent to such assignment required by paragraph (b) of this
Section, the Administrative Agent shall accept such Assignment and Acceptance and record the
information contained therein in the Register and will provide prompt written notice to Borrower of
the effectiveness of such Assignment. No assignment shall be effective for purposes of this
Agreement unless it has been recorded in the Register as provided in this paragraph.

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

55

 

directly with such Lender in connection with such Lender’s rights and obligations under this
Agreement, and (iv) if such Participant is not a Lender or an Affiliate of a Lender, such Lender
shall have given notice to Borrower of the name of the Participant and the amount of such
participation. Any agreement or instrument pursuant to which a Lender sells such a participation
shall provide that such Lender shall retain the sole right to enforce this Agreement and to approve
any amendment, modification or waiver of any provision of this Agreement; provided that such
agreement or instrument may provide that such Lender will not, without the consent of the
Participant, agree to any amendment, modification or waiver described in clauses (ii) and (iii) of
the first proviso to Section 10.2(b) that affects such Participant. Subject to paragraph
(f) of this Section, Borrower agrees that each Participant shall be entitled to the benefits of
Sections 2.14, 2.15 and 2.16 to the same extent as if it were a Lender and
had acquired its interest by assignment pursuant to paragraph (b) of this Section. To the extent
permitted by law, each Participant also shall be entitled to the benefits of Section 10.8
as though it were a Lender, provided such Participant agrees to be subject to Section
2.17(c) as though it were a Lender.

     (f) A Participant shall not be entitled to receive any greater payment under Sections
2.14, 2.15 or 2.16 than the applicable Lender would have been entitled to
receive with respect to the participation sold to such Participant, unless Borrower shall expressly
agree otherwise in
writing. A Participant that would be a Foreign Lender if it were a Lender shall not be
entitled to the benefits of Section 2.16 unless Borrower is notified of the participation
sold to such Participant and such Participant agrees, for the benefit of Borrower, to comply with
Section 2.16(e) as though it were a Lender.

     (g) 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 to a Federal Reserve Bank or,
in the case of a Lender organized in a jurisdiction outside of the United States, a comparable
Person, and this Section shall not apply to any such pledge or assignment of a security interest;
provided that no such pledge or assignment of a security interest shall release a Lender from any
of its obligations hereunder or substitute any such pledgee or assignee for such Lender as a party
hereto.

     SECTION 10.5 Survival. All covenants, agreements, representations and warranties made by Borrower
herein and in the certificates or other instruments delivered in connection with or pursuant to
this Agreement shall be considered to have been relied upon by the other parties hereto and shall
survive the execution and delivery of this Agreement and the making of any Loans and issuance of
any Letters of Credit, regardless of any investigation made by any such other party or on its
behalf and notwithstanding that the Administrative Agent, any Issuing Bank or any Lender may have
had notice or knowledge of any Default or incorrect representation or warranty at the time any
credit is extended hereunder, and shall continue in full force and effect as long as the principal
of or any accrued interest on any Loan or any fee or any other amount payable under this Agreement
is outstanding and unpaid or any Letter of Credit is outstanding and so long as the Commitments
have not expired or terminated. The provisions of Sections 2.14, 2.15,
2.16, 2.17 and 10.3 and Article IX shall survive and remain in full
force and effect regardless of the consummation of the transactions contemplated hereby, the
repayment of the Loans, the expiration or termination of the Letters of Credit and the Commitments
or the termination of this Agreement or any provision hereof.

56

 

     SECTION
10.6 Counterparts; Integration; Effectiveness. This Agreement may be executed in
counterparts (and by different parties hereto on different counterparts), each of which shall
constitute an original, but all of which when taken together shall constitute a single contract.
This Agreement and any separate letter agreements with respect to fees payable to the
Administrative Agent constitute the entire contract among the parties relating to the subject
matter hereof and supersede any and all previous agreements and understandings, oral or written,
relating to the subject matter hereof. Except as provided in Section 4.1, this Agreement
shall become effective when it shall have been executed by the Administrative Agent and when the
Administrative Agent shall have received counterparts hereof which, when taken together, bear the
signatures of each of the other parties hereto, and thereafter shall be binding upon and inure to
the benefit of the parties hereto and their respective successors and assigns. Delivery of an
executed counterpart of a signature page of this Agreement by telecopy shall be effective as
delivery of a manually executed counterpart of this Agreement.

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

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

     SECTION 10.9 GOVERNING LAW; JURISDICTION; CONSENT TO SERVICE OF PROCESS.

     (a) THIS AGREEMENT AND THE OTHER LOAN DOCUMENTS SHALL BE CONSTRUED IN ACCORDANCE WITH AND
GOVERNED BY THE LAW OF THE STATE OF NEW YORK.

     (b) BORROWER HEREBY IRREVOCABLY AND UNCONDITIONALLY SUBMITS, FOR ITSELF AND ITS PROPERTY, TO
THE NONEXCLUSIVE JURISDICTION OF THE SUPREME COURT OF THE STATE OF NEW YORK SITTING IN NEW YORK
COUNTY AND OF THE UNITED STATES DISTRICT COURT OF THE SOUTHERN DISTRICT OF NEW YORK, AND ANY
APPELLATE COURT FROM ANY THEREOF, IN ANY ACTION OR PROCEEDING ARISING OUT OF OR RELATING TO THIS
AGREEMENT, OR FOR RECOGNITION OR ENFORCEMENT OF ANY JUDGMENT, AND EACH OF THE PARTIES HERETO HEREBY
IRREVOCABLY AND UNCONDITIONALLY AGREES THAT ALL CLAIMS IN RESPECT OF ANY SUCH ACTION OR PROCEEDING

57

 

MAY BE HEARD AND DETERMINED IN SUCH NEW YORK STATE OR, TO THE EXTENT PERMITTED BY LAW, IN SUCH
FEDERAL COURT. EACH OF THE PARTIES HERETO AGREES THAT A FINAL JUDGMENT IN ANY SUCH ACTION OR
PROCEEDING SHALL BE CONCLUSIVE AND MAY BE ENFORCED IN OTHER JURISDICTIONS BY SUIT ON THE JUDGMENT
OR IN ANY OTHER MANNER PROVIDED BY LAW. NOTHING IN THIS AGREEMENT SHALL AFFECT ANY RIGHT THAT THE
AGENTS, THE ISSUING BANK OR ANY LENDER MAY OTHERWISE HAVE TO BRING ANY ACTION OR PROCEEDING
RELATING TO THIS AGREEMENT AGAINST BORROWER OR ITS PROPERTIES IN THE COURTS OF ANY JURISDICTION.

     (c) BORROWER HEREBY IRREVOCABLY AND UNCONDITIONALLY WAIVES, TO THE FULLEST EXTENT IT MAY
LEGALLY AND EFFECTIVELY DO SO, ANY OBJECTION WHICH IT MAY NOW OR HEREAFTER HAVE TO THE LAYING OF
VENUE OF ANY SUIT, ACTION OR PROCEEDING ARISING OUT OF OR RELATING TO THIS AGREEMENT IN ANY COURT
REFERRED TO IN THE FIRST SENTENCE OF PARAGRAPH (b) OF THIS SECTION. EACH OF THE PARTIES HERETO
HEREBY IRREVOCABLY WAIVES, TO THE FULLEST EXTENT PERMITTED BY LAW, THE DEFENSE OF AN INCONVENIENT
FORUM TO THE MAINTENANCE OF SUCH ACTION OR PROCEEDING IN ANY SUCH COURT.

     (d) EACH PARTY TO THIS AGREEMENT IRREVOCABLY CONSENTS TO SERVICE OF PROCESS BY REGISTERED
MAIL, POSTAGE PREPAID, OR BY PERSONAL SERVICE WITHIN OR WITHOUT THE STATE OF NEW YORK. NOTHING IN
THIS AGREEMENT WILL AFFECT THE RIGHT OF ANY PARTY TO THIS AGREEMENT TO SERVE PROCESS IN ANY OTHER
MANNER PERMITTED BY LAW.

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

     SECTION
10.11 Confidentiality. Each of the Agents, the Issuing Banks and the Lenders agrees to
maintain the confidentiality of the Information (as defined below), except that Information may be
disclosed (a) to its and its Affiliates’ directors, officers, employees and agents, including
accountants, legal counsel and other advisors (it being understood that the Persons to whom such
disclosure is made will be informed of the confidential nature of such Information and instructed
to keep such Information confidential), (b) to the extent requested by any regulatory or
self-regulatory authority, (c) to the extent required by applicable laws or regulations or by any
subpoena or similar legal process, (d) to any other party to this Agreement, (e) in connection with
the exercise of any remedies hereunder or any suit, action or proceeding relating to this Agreement
or the enforcement of rights hereunder, (f) subject to an agreement containing provisions
substantially the same as those of this Section, to any assignee of or Participant in, or any
prospective assignee of or Participant in, any of its rights or obligations under this Agreement,
(g) with the consent of Borrower or (h) to the extent such Information (A) becomes publicly
available other than as a result of a breach of this Section by any Person or (B) becomes available
to any Agent, any Issuing Bank or any Lender on a non-confidential basis from a source other than
Borrower or any Person obligated to maintain the confidentiality of such Information. Prior to
disclosing any Information under clause (c) above, the Agent, the

58

 

Issuing Bank or Lender required or asked to make such disclosure shall make a good faith
effort to give Borrower prior notice of such proposed disclosure to permit Borrower to attempt to
obtain a protective order or other appropriate injunctive relief. For the purposes of this
Section, “Information” means all information received from Borrower relating to Borrower or
its business, other than any publicly available information and such information that is available
to any Agent, any Issuing Bank or any Lender on a non-confidential basis prior to disclosure by
Borrower; provided that, in the case of information received from Borrower after the date hereof,
such information is clearly identified at the time of delivery as confidential. Any Person
required to maintain the confidentiality of Information as provided in this Section shall be
considered to have complied with its obligation to do so if such Person has exercised the same
degree of care to maintain the confidentiality of such Information as such Person would accord to
its own confidential information.

     SECTION 10.12 Interest Rate Limitation. It is the intention of the parties hereto to conform
strictly to applicable interest, usury and criminal laws and, anything herein to the contrary
notwithstanding, the obligations of Borrower to a Lender or any Agent under this Agreement shall be
subject to the limitation that payments of interest shall not be required to the extent that
receipt thereof would be contrary to provisions of law applicable to such Lender or Agent limiting
rates of interest which may be charged or collected by such Lender or Agent. Accordingly, if the
transactions contemplated hereby would be illegal, unenforceable, usurious or criminal under laws
applicable to a Lender or Agent (including the laws of any jurisdiction whose laws may be
mandatorily applicable to such Lender or Agent notwithstanding anything to the contrary in this
Agreement or any other Loan Document but subject to Section 2.12 hereof) then, in that
event, notwithstanding anything to the contrary in this Agreement or any other Loan Document, it is
agreed as follows:

     (i) the provisions of this Section shall govern and control;

     (ii) the aggregate of all consideration which constitutes interest under applicable law
that is contracted for, taken, reserved, charged or received under this Agreement, or under
any of the other aforesaid agreements or otherwise in connection with this Agreement by such
Lender or Agent shall under no circumstances exceed the maximum amount of interest allowed
by applicable law (such maximum lawful interest rate, if any, with respect to each Lender
and the Agent herein called the “Highest Lawful Rate”), and any excess shall be
cancelled automatically and if theretofore paid shall be credited to Borrower by such Lender
or Agent (or, if such consideration shall have been paid in full, such excess refunded to
Borrower);

     (iii) all sums paid, or agreed to be paid, to such Lender or Agent for the use,
forbearance and detention of the indebtedness of Borrower to such Lender or Agent hereunder
or under any Loan Document shall, to the extent permitted by laws applicable to such Lender
or Agent, as the case may be, be amortized, prorated, allocated and spread throughout the
full term of such indebtedness until payment in full so that the actual rate of interest is
uniform throughout the full term thereof;

     (iv) if at any time the interest provided pursuant to this Section or any other clause
of this Agreement or any other Loan Document, together with any other fees or

59

 

compensation payable pursuant to this Agreement or any other Loan Document and deemed
interest under laws applicable to such Lender or Agent, exceeds that amount which would have
accrued at the Highest Lawful Rate, the amount of interest and any such fees or compensation
to accrue to such Lender or Agent pursuant to this Agreement shall be limited,
notwithstanding anything to the contrary in this Agreement or any other Loan Document, to
that amount which would have accrued at the Highest Lawful Rate, but any subsequent
reductions, as applicable, shall not reduce the interest to accrue to such Lender or Agent
pursuant to this Agreement below the Highest Lawful Rate until the total amount of interest
accrued pursuant to this Agreement or such other Loan Document, as the case may be, and such
fees or compensation deemed to be interest equals the amount of interest which would have
accrued to such Lender or Agent if a varying rate per annum equal to the interest provided
pursuant to any other relevant Section hereof (other than this Section), as applicable, had
at all times been in effect, plus the amount of fees which would have been received but for
the effect of this Section; and

     (v) with the intent that the rate of interest herein shall at all times be lawful, and
if the receipt of any funds owing hereunder or under any other agreement related hereto
(including any of the other Loan Documents) by such Lender or Agent would cause such Lender
to charge Borrower a criminal rate of interest, the Lenders and the Agents agree that they
will not require the payment or receipt thereof or a portion thereof which would cause a
criminal rate of interest to be charged by such Lender or Agent, as applicable, and if
received such affected Lender or Agent will return such funds to Borrower so that the rate
of interest paid by Borrower shall not exceed a criminal rate of interest from the date this
Agreement was entered into.

     SECTION
10.13 USA PATRIOT Act Notice. Each Lender that is subject to the USA Patriot Act and the
Administrative Agent (for itself and not on behalf of any Lender) hereby notifies Borrower that,
pursuant to the requirements of the USA Patriot Act, it is required to obtain, verify and record
information that identifies Borrower, which information includes the name and address of Borrower
and other information that will allow such Lender or the Administrative Agent, as applicable, to
identify Borrower in accordance with the USA Patriot Act.

     SECTION
10.14 NO ORAL AGREEMENTS. THIS WRITTEN AGREEMENT AND THE OTHER 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 AMONG THE PARTIES.
