reference to the following facts:

R E C I T A L S

	A.	 	Landlord and Tenant previously executed that certain Office Lease dated November 5, 1999 (the
“Original Lease”) pursuant to which Tenant leased from Landlord certain Premises

not leased by Tenant in Building “A”, 26701 W. Agoura Road, Calabasas, CA.(the “Original
Lease”, the “First Amendment”, the “Second Amendment” and the “Third
Amendment” are sometimes collectively referred to herein as the “Lease”; the
“Original Premises” as expanded pursuant to the First Amendment, the Second Amendment
and the Third Amendment, is sometimes referred to as the “Premises”);
	 
	E.	 	Tenant desires to further expand the Premises under the Lease to include additional space in
another building in the Project, which building is commonly known as Building “C”, 26677 W.
Agoura Road, Calabasas, California, and Landlord is willing to lease such additional space to
Tenant subject to and as provided for in this Amendment; and
	 
	F.	 	Landlord and Tenant desire to modify the Lease as provided in this Amendment,

          NOW THEREFORE, in consideration of the mutual covenants and agreements contained herein and
for other good and valuable consideration, the receipt and sufficiency of which are hereby
acknowledged, Landlord and Tenant agree as follows:

A G R E E M E N T

	1.	 	Fourth Expansion Premises. From and after the “Fourth Expansion Premises
Commencement Date” (as defined in Section 2 below), the “Premises” leased
to Tenant pursuant to the Lease shall for all purposes be deemed to also include that certain
space (the

1

 

	 	 	“Fourth Expansion Premises”) located on the first (1st) floor of
Building “C”, which space is commonly known as 26677 W. Agoura Road, Suite 101, Calabasas,
California, as more particularly shown in Exhibit “A” attached hereto and
incorporated by this reference herein. The Fourth Expansion Premises is agreed by the
parties to contain twelve thousand five hundred twelve (12,512) square feet of Rentable
Area, notwithstanding any deviation therefrom. The entire Premises is agreed by the parties
to contain a total of eighty-four thousand one hundred twenty-four (84,124) square feet of
Rentable Area (notwithstanding any deviation therefrom), which is comprised of fifty
thousand (50,000) square feet, and the entirety of, Building Two, twenty-one thousand six
hundred twelve (21,612) square feet in, and the entirety of, Building “A”, and twelve
thousand five hundred twelve (12,512) in Building “C”. References to the “Building”
contained in the Lease shall pertain to the either or all of Building Two, Building “A”
and/or Building “C”, as the context requires.
	 
	2.	 	Fourth Expansion Premises Commencement Date. The term of Tenant’s lease of the
Fourth Expansion Premises shall commence on November 1, 2005 (the “Fourth Expansion
Premises Commencement Date”), and shall expire on January 31, 2009 (the “Fourth
Expansion Premises Expiration Date”) (the period beginning on the Fourth Expansion
Premises Commencement Date and ending on the Fourth Expansion Premises Expiration Date is
referred to herein as the “Fourth Expansion Premises Term”), unless earlier terminated
pursuant to the provisions of the Lease. The Tenant shall vacate the Fourth Expansion
Premises on or before the Fourth Expansion Premises Expiration Date on the terms and
conditions set forth in the Lease. Tenant acknowledges that the scheduled Fourth Expansion
Premises Expiration Date and the scheduled expiration date of the term of the lease for the
remainder of the Premises are scheduled to occur on different dates.
	 
	3.	 	Base Rent; Percentage Share; Base Year; Utilities.

a. Commencing on the Fourth Expansion Premises Commencement Date and continuing throughout
the Fourth Expansion Premises Term, the Base Rent payable by Tenant for the Fourth Expansion
Premises shall be Twenty Thousand Dollars ($20,000) per month. Tenant shall continue to
pay Base Rent and Escalation Rent on the other portions of the Premises as provided in the
Lease.

b. Commencing on the Fourth Expansion Premises Rent Commencement Date, Tenant’s Percentage
Share of Building Operating Expenses and Building Tax Expenses shall be Twenty-eight point
seven percent (28.7%) for the Fourth Expansion Premises. The Fourth Expansion Premises will
be leased to Tenant on a “modified gross”, which means that Tenant, in addition to Tenant’s
obligation to pay Base Rent for the Fourth Expansion Premises, shall also pay to Landlord
Escalation Rent for the Fourth Expansion Premises, which shall be calculated for the Fourth
Expansion Premises on the terms and conditions as set forth for the payment of Escalation
Rent for the Third Expansion Premises; provided, however that the Base Year for the Fourth
Expansion Premises shall be calendar year 2006 and Tenant’s Percentage Share of Building
Operating Expenses for the Fourth Expansion Premises shall be as set forth above.

c. Notwithstanding anything to the contrary contained in the Lease, Tenant, at its sole
cost and expense, shall procure its own janitorial service for the Fourth Expansion Premises
at least five (5) days a week, but Landlord shall have the right upon thirty (30) days’
prior written notice to Tenant to take over the obligation to provide janitorial services
for the Fourth Expansion Premises, in which case Landlord may charge the cost therefor (as
reasonably determined by Landlord) to Tenant as additional rent.

d. Notwithstanding anything to the contrary contained in the Lease, Tenant shall be
responsible for paying for all electrical and other utility services for the Fourth
Expansion Premises, regardless of whether or not the Lease states that such costs shall be
paid by

2

 

Tenant. If any such electrical and other utility services are separately metered for the
Fourth Expansion Premises, then Tenant shall pay the cost thereof directly to the electrical
supplier. If any such electrical and other utility services are not separately metered for
the Fourth Expansion Premises, then Tenant shall reimburse Landlord for a proportionate
share of the charges applicable to the Fourth Expansion Premises, as reasonably determined
by Landlord.

	4.	 	Furniture, Fixtures and Improvements in the Fourth Expansion Premises. Tenant
acknowledges that it has arranged with the prior tenant of the Fourth Expansion Premises to
assume any and all payments on certain furniture, fixtures, improvements and other personal
property, inclusive of associated existing cabling and telephone lines (the “FF&E”), which was
placed at the Fourth Expansion Premises by Landlord’s prior tenant. Accordingly, the FF&E
shall remain on the Fourth Expansion Premises as of the Effective Date. Notwithstanding
anything to the contrary contained in this Section, Tenant acknowledges that Landlord shall
have no liability to Tenant based upon any adverse or other claims of third parties against
the FF&E, Tenant acknowledging that Landlord has no interest in the FF&E; provided, however,
that nothing contained herein shall be construed to relieve Landlord of its obligation no to
remove or move any FF&E pursuant to Section 7 of this Agreement. Tenant shall be obligated
to remove the FF&E from the Fourth Expansion Premises on or prior to the Fourth Expansion
Premises Expiration Date, on the terms and conditions applicable to the other portions of the
Premises under the Lease. Tenant agrees to indemnify, defend and hold Landlord harmless from
any liability or lien arising out of the payment, non-payment, or use of the FF&E.
	 
	5.	 	Early Possession. Subject to the rights of the prior tenant of Landlord currently
occupying the Fourth Expansion Premises, Tenant shall be permitted access to the Fourth
Expansion Premises prior to the Fourth Expansion Premises Commencement Date for the purpose of
installing over standard equipment or fixtures (including Tenant’s data and telephone
equipment) in the Fourth Expansion Premises. Prior to any such entry upon the Fourth Expansion
Premises, Tenant shall deliver to Landlord evidence of the satisfaction of Tenant’s insurance
obligations set forth in the Lease. Any such occupancy of the Premises by Tenant prior to the
Fourth Expansion Premises Commencement Date shall be subject to all applicable provisions of
the Lease (including, without limitation, the indemnity and insurance provisions of Lease
Sections 12 and 13) other than the obligation for the payment of Base Rent and Escalation
Rent.
	 
	6.	 	Surrender of Existing Tenant. Notwithstanding anything contained in this Fourth
Amendment to the contrary, Landlord’s obligations and Tenant’s rights under this Fourth
Amendment shall be contingent upon Landlord’s ability to cause the tenant currently occupying
the Fourth Expansion Premises to vacate and surrender the Fourth Expansion Premises to
Landlord by January 10, 2006, on such terms and conditions as are acceptable to Landlord, in
its sole and absolute discretion. This Amendment shall be voidable by Landlord or Tenant if
Landlord is not able to procure such surrender.
	 
	7.	 	As-Is/Cleaning of Fourth Expansion Premises. Except to the extent specifically
otherwise provided in this paragraph, Landlord shall deliver and Tenant shall accept the
Fourth Expansion Premises to Tenant on the Fourth Expansion Premises Commencement Date in an
“as is” condition with no alterations or improvements being made by Landlord. However,
Landlord agrees to clean the Fourth Expansion Premises after the tenant currently occupying
the Fourth Expansion Premises vacates the Fourth Expansion Premises; provided, however,
Landlord shall not remove or move any FF&E in the Fourth Expansion Premises.
	 
	8.	 	Miscellaneous.

a. Landlord and Tenant acknowledge and agree that this Amendment is subject to Landlord’s
receiving from its mortgagee(s) approval of all of the terms contained herein.

b. Initially capitalized terms used herein shall have the same meaning as those defined in the

3

 

Original Lease, the First Amendment, the Second Amendment or the Third Amendment, as
applicable, unless expressly contradicted in this Amendment.

c. The submission of the Amendment is only an invitation to deal and shall not be deemed an
offer by Landlord. Only a fully executed and delivered Amendment shall bind the parties
hereto.

d. In the event of a conflict between the provisions of this Amendment and those of the Lease,
the provisions of this Amendment shall control. Except for purposes of determining whether a
conflict exists between the Lease and this Amendment, the term “Lease” as used herein shall
include the provisions of the Original Lease, the First Amendment, the Second Amendment the
Third Amendment and this Amendment. This Amendment is deemed to have been jointly prepared by
the parties, and shall not be interpreted against any party as drafter.

e. Except as expressly provided herein, all of the terms and provisions contained in the Lease
remain unmodified.

          IN WITNESS WHEREOF, Landlord and Tenant have executed this Amendment as of the date first set
forth above.

as Issuing Bank.

     The parties hereto agree as follows:

ARTICLE I

DEFINITIONS

     Section 1.01 Defined Terms. As used in this Agreement, the following terms have the
meanings specified below:

     “ABR”, when used in reference to any Loan or Borrowing, refers to whether such Loan,
or the Loans comprising such Borrowing, are bearing interest at a rate determined by reference to
the Alternate Base Rate.

     “Adjusted LIBO Rate” means, with respect to any Eurodollar Borrowing for any Interest
Period, an interest rate per annum (rounded upwards, if necessary, to the next 1/16 of 1%) equal to
(a) the LIBO Rate for such Interest Period multiplied by (b) the Statutory Reserve Rate.

     “Administrative Agent” means JPMorgan Chase Bank, N.A. in its capacity as
administrative agent for the Lenders hereunder.

     “Administrative Questionnaire” means an Administrative Questionnaire in a form
supplied by the Administrative Agent.

     “Affiliate” means, with respect to a specified Person, another Person that directly,
or indirectly through one or more intermediaries, Controls or is Controlled by or is under common
Control with the Person specified.

     “Agreement” means this Credit Agreement, as the same may be amended, modified, restated, or replaced from time to time.

     “Alternate Base Rate” means, for any day, a rate per annum equal to the greater of (a)
the Prime Rate in effect on such day and (b) the Federal Funds Effective Rate in effect on such day
plus 1/2 of 1%. Any change in the Alternate Base Rate due to a change in the Prime Rate or the
Federal Funds Effective Rate shall be effective from and including the effective date of such
change in the Prime Rate or the Federal Funds Effective Rate, respectively.

     “Applicable Margin” means, for any day, with respect to any Eurodollar Loan, or with
respect to any Letter of Credit or commitment fees payable hereunder, as the case may be, the
Applicable Margin per annum set forth below under the caption “Eurodollar Spread,” “Commitment Fee
Rate” or “Letter of Credit Rate,” as the case may be, based upon the ratings by Moody’s and S&P,
respectively, applicable on such date to the Index Debt:

1

 

	 	 	 	 	 	 	 	 	 	 	 	 	 
	 	 	Eurodollar	 	Commitment Fee	 	Letter of Credit
	Index Debt Ratings:	 	Spread	 	Rate	 	Rate
	Category 1
	 	 	0.625	%	 	 	0.125	%	 	 	0.50	%
	BBB/Baa2 or higher
	 	 	 	 	 	 	 	 	 	 	 	 
	Category 2
	 	 	0.75	%	 	 	0.15	%	 	 	0.625	%
	BBB-/Baa3
	 	 	 	 	 	 	 	 	 	 	 	 
	Category 3
	 	 	1.00	%	 	 	0.20	%	 	 	0.875	%
	BB+/Ba1
	 	 	 	 	 	 	 	 	 	 	 	 
	Category 4
	 	 	1.25	%	 	 	0.30	%	 	 	1.125	%

	BB-/Ba3 or lower
	 	 	 	 	 	 	 	 	 	 	 	 

     For purposes of the foregoing, (i) if neither Moody’s nor S&P shall have in effect a
rating for the Index Debt (other than by reason of the circumstances referred to in the last
sentence of this definition), then such rating agencies shall be deemed to have established a
rating in Category 5; (ii) if only one of Moody’s and S&P has in effect a rating for the Index
Debt, then the Applicable Rate shall be determined solely based on the rating of such rating
agency; (iii) if the ratings established or deemed to have been established by Moody’s and S&P for
the Index Debt shall fall within different Categories, the Applicable Rate shall be based on the
higher of the two ratings unless one of the two ratings is two or more Categories lower than the
other, in which case the Applicable Rate shall be determined by reference to the Category next
above that of the lower of the two ratings; and (iv) if the ratings established or deemed to have
been established by Moody’s and S&P for the Index Debt shall be changed (other than as a result of
a change in the rating system of Moody’s or S&P), such change shall be effective as of the date on
which it is first announced by the applicable rating agency, irrespective of when notice of such
change shall have been furnished by the Borrower to the Administrative Agent and the Lenders
pursuant to Section 5.01 or otherwise. Each change in the Applicable Rate shall apply during the

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 and such other
information as shall be necessary to prepare, amend, renew or extend such Letter of Credit. If
requested by an 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 that no provision in such application shall be deemed effective to the extent
such provision contains, provides for, or requires, representations, warranties, covenants,
security interests, Liens, indemnities, reimbursements of costs or expenses, events of defaults,
remedies, or standards of care or to the extent such provision conflicts or is inconsistent with
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 total

23

 

Credit Exposures shall not exceed the total Commitments and (ii) the LC
Exposure shall not exceed in the aggregate $250,000,000 at any time.

          (c) Expiration Date. Each Letter of Credit shall expire at or prior to the close of
business on the earlier of (i) the date one year after the date of the issuance of such Letter of
Credit (or, in the case of any renewal or extension thereof, one year after such renewal or
extension) and (ii) the date that is five Business Days prior to the Maturity Date.

          (d) Participation. 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
Issuing Banks or the Lenders, the Issuing Banks hereby grant to each Lender, and each Lender
hereby acquires from the Issuing Banks, 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 Lender hereby absolutely and
unconditionally agrees to pay to the Administrative Agent, for the account of the Issuing Banks,
such Lender’s Applicable Percentage of each LC Disbursement made by the Issuing Banks and not
reimbursed by the Borrower on the date due as provided in paragraph (e) below, and 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 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) Reimbursement. If an Issuing Bank shall make any LC Disbursement in respect of a
Letter of Credit, the Borrower shall reimburse such LC Disbursement by paying to the
Administrative Agent an amount equal to such LC Disbursement not later than 1:00 p.m., New York
City time, on the date that such LC Disbursement is made, if the Borrower shall have received
notice of such LC Disbursement prior to 10:00 a.m., New York City time, on such date, or, if such
notice has not been received by the Borrower prior to such time on such date, then not later than
12:00 noon, New York City time, on (i) the Business Day that the Borrower receives such notice, if
such notice is received prior to 10:00 a.m., New York City time, on the day of receipt, or (ii)
the Business Day immediately following the day that the Borrower receives such notice, if such
notice is not received prior to such time on the day of receipt; provided that, if such LC
Disbursement is not less than $5,000,000, the Borrower may, subject to the conditions to borrowing
set forth herein, request in accordance with Section 2.04 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 shall be discharged and replaced by the resulting ABR Borrowing. If the
Borrower fails to make such payment 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 2.06 with respect to Loans made by such Lender
(and Section 2.06 shall apply, mutatis mutandis, to the payment obligations of the Lenders), and
the Administrative Agent shall promptly pay to the applicable Issuing Banks the amounts so

24

 

received by it from the Lenders. Promptly following receipt by the Administrative Agent of any
payment from the Borrower pursuant to this paragraph, the Administrative Agent shall distribute
such payment to the applicable Issuing Banks or, to the extent that Lenders have made payments
pursuant to this paragraph to reimburse such Issuing Banks, then to such Lenders and Issuing Banks
as their interests may appear. Any payment made by a Lender pursuant to this paragraph to
reimburse the applicable Issuing Banks 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) Obligations Absolute. The Borrower’s obligation to reimburse LC Disbursements as
provided in paragraph (e) above 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, or (iii) any other event or
circumstance whatsoever, whether or not similar to any of the foregoing, that might, but for the
provisions of this Section, constitute a legal or equitable discharge of, or provide a right of
setoff against, the Borrower’s obligations hereunder. Neither the Administrative Agent, the
Lenders nor 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
Issuing Banks; 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 consequential
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
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 an 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 Issuing Banks may, in their 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) Disbursement Procedures. The Issuing Bank that issued a Letter of Credit shall,
promptly following receipt thereof, examine all documents purporting to represent a demand for
payment under such Letter of Credit. Such Issuing Bank shall promptly notify the Administrative
Agent and the Borrower by telephone (confirmed by telecopy) of such demand

25

 

for payment and whether
the Issuing Banks have 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 the Issuing Banks and the Lenders with respect to any such LC Disbursement.

          (h) Interim Interest. 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 when due pursuant to paragraph (e) above, then
Section 2.12(c) shall apply. Interest accrued pursuant to this paragraph shall be for the account
of the relevant Issuing Bank, except that interest accrued on and after the date of payment by any
Lender pursuant to paragraph (e) of this Section to reimburse such Issuing Bank shall be for the
account of such Lender to the extent of such payment.

          (i) Additional and Replacement Issuing Banks. Any other Lender in addition to
JPMorgan Chase Bank, N.A. selected by the Borrower and agreed to by such Lender may become an
Issuing Bank. The Borrower shall provide JPMorgan Chase Bank, N.A. notice of any such additional
Issuing Bank. An Issuing Bank may be replaced at any time by written agreement among the
Borrower, the Administrative Agent, the replaced Issuing Bank and the successor Issuing Bank. The
Administrative Agent shall notify the Lenders of any such replacement of an Issuing Bank. At the
time any such replacement shall become effective, the Borrower shall pay all unpaid fees accrued
for the account of the replaced Issuing Bank pursuant to Section 2.11(b). From and after the
effective date of any such replacement, (i) the successor Issuing Bank shall have all the rights
and obligations of the Issuing Bank under this Agreement with respect to Letters of Credit to be
issued thereafter and (ii) references herein to the term “Issuing Bank” shall be deemed to refer
to such successor or to any previous Issuing Bank, or to such successor and all previous Issuing
Banks, as the context shall require. After the replacement of an Issuing Bank hereunder, the
replaced Issuing Bank shall remain a party hereto and shall continue to have all the rights and
obligations of an Issuing Bank under this Agreement with respect to Letters of Credit issued by it
prior to such replacement, but shall not be required to issue additional Letters of Credit or to
amend, extend or renew any Letter of Credit.

          (j) Cash Collateralization. If the Loans have become due and payable (A) pursuant to
Article VII (other than pursuant to clause (h) or (i) of such Article VII), on the Business Day
following the Business Day that the Borrower receives notice from the Administrative Agent (at the
direction of Required Lenders) or the Required Lenders demanding the deposit of cash collateral
pursuant to this paragraph, or (B) pursuant to clause (h) or (i) of Article VII, without any
demand or the taking of any other action by the Issuing Banks, the Administrative Agent, or any of
the Lenders, the Borrower shall deposit in an account with the Administrative Agent, in the name
of the Administrative Agent and for the benefit of the Issuing Banks and the Lenders, an amount in
cash equal to the LC Exposure as of such date plus any accrued and unpaid interest on LC
Disbursements comprising such LC Exposure. Such deposit shall be held by the Administrative Agent
as collateral for the payment

26

 

and performance of the obligations of the Borrower under this
Agreement. The Administrative Agent shall have exclusive dominion and control, including the
exclusive right of withdrawal, over such account (which shall be invested in obligations of,
obligations guaranteed by, or obligations backed by the full faith and credit of, the United
States of America, certificates of deposit of Administrative Agent or commercial paper having the
highest rating from S&P or Moody’s, in each case maturing in less than 180 days). Other than any
interest earned on the investment of such deposits, which investments shall be made at 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 an Issuing Bank for LC Disbursements for which it has not been reimbursed and, to the
extent not so applied, shall be held for the satisfaction of the reimbursement obligations of the
Borrower for the LC Exposure at such time or, if the maturity of the Loans has been accelerated
(but subject to the consent of Lenders with LC Exposure representing greater than 50% of the total
LC Exposure), be applied to satisfy other obligations of the Borrower under this Agreement.

     Section 2.06 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 pm, 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 the Borrower by promptly crediting the
amounts so received, in like funds, to an account of the Borrower maintained with the
Administrative Agent in New York City and designated by the Borrower in the applicable Borrowing
Request; provided that ABR Loans made to finance the reimbursement of an LC Disbursement as
provided in Section 2.05(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 such date in accordance with paragraph (a) of this Section and
may, in reliance upon such assumption, make available to the 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 the 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 the 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 and a rate determined by the Administrative Agent in
accordance with banking industry rules on interbank compensation or (ii) in the case of the
Borrower, the interest rate applicable to the applicable Borrowing. If such Lender pays such
amount to the Administrative Agent, then such amount shall constitute such Lender’s Loan included
in such Borrowing.

27

 

     Section 2.07 Interest Elections. 

          (a) Each Borrowing initially shall be of the Type specified in the applicable Borrowing
Request and, in the case of a Eurodollar Borrowing, shall have an initial Interest Period as
specified in such Borrowing Request. Thereafter, the 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. The Borrower may elect
different options with respect to different portions of the affected Borrowing, in which case each
such portion shall be allocated ratably among the 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, the Borrower shall notify the
Administrative Agent of such election by telephone by the time that a Borrowing Request would be
required under Section 2.04 if the 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 in a form approved by the
Administrative Agent and signed by the Borrower.

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

     (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

     (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 the 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 the 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

28

 

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 the 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, each Eurodollar Borrowing shall be converted to an ABR Borrowing at the end of the
Interest Period applicable thereto.

     Section 2.08 Termination and Reduction of Commitments. 

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

          (b) The 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) the 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 total Credit Exposures would exceed the
Commitments.

          (c) The Borrower shall notify the Administrative Agent of any election to terminate or reduce
the Commitments under paragraph (b) of this Section at least three 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 the Borrower pursuant to this Section
shall be irrevocable; provided that a notice of termination of the Commitments delivered
by the Borrower may state that such notice is conditioned upon the effectiveness of other credit
facilities, in which case such notice may be revoked by the 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
Applicable Percentages.

     Section 2.09 Repayment of Loans; Evidence of Debt. 

          (a) The 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.

          (b) Each Lender shall maintain in accordance with its usual practice an account or accounts
evidencing the indebtedness of the 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 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 the Borrower
to each Lender hereunder and (iii) the amount of any sum

29

 

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 the 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 a promissory note. In such
event, the Borrower shall prepare, execute and deliver to such Lender a promissory note payable to
the order of such Lender (or, if requested by such Lender, to such Lender and its registered
assigns) and substantially in the form attached hereto as Exhibit E. Thereafter, the Loans
evidenced by such promissory note and interest thereon shall at all times (including after
assignment pursuant to Section 9.04) be represented by one or more promissory notes in such form
payable to the order of the payee named therein (or, if such promissory note is a registered note,
to such payee and its registered assigns).

     Section 2.10 Prepayment of Loans. 

          (a) Subject to any breakage funding costs payable pursuant to Section 2.15, the Borrower
shall have the right at any time and from time to time to prepay any Borrowing in whole or in part
without premium or penalty, provided that each prepayment is in an amount that is an integral
multiple of $1,000,000 and not less than $5,000,000, or if such amount is lesser, the outstanding
amount of the Borrowing, and made subject to prior notice in accordance with paragraph (b) of this
Section.

          (b) The 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 12:00 noon, 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 12:00 noon, 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 termination of
the Commitments as contemplated by Section 2.08, then such notice of prepayment may be revoked if
such notice of termination is revoked in accordance with Section 2.08. 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
2.03. 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.

30

 

     Section 2.11 Fees.

          (a) The Borrower agrees to pay to the Administrative Agent for the account of each Lender a
commitment fee, which shall accrue at the Applicable Margin for commitment fees on the daily
amount of the unused Commitment of such Lender during the period from and including the date
hereof to but excluding the date on which such Commitment terminates. Accrued Commitment fees
shall be payable in arrears on the last day of March, June, September and December of each year
and on the date on which the Commitments terminate, commencing on the first such date to occur
after the date hereof. All commitment 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).

          (b) The Borrower agrees to pay (i) to the Administrative Agent for the account of each Lender
a participation fee with respect to its participations in Letters of Credit, which shall accrue at
the Applicable Margin for Letters of Credit on the average daily amount of such Lender’s 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 on which such
Lender’s Commitment terminates and the date on which such Lender ceases to have any LC Exposure;
provided that the minimum participation fee payable to any Lender with respect to any Letter of
Credit will be $500 times such Lender’s Applicable Percentage, and (ii) to the Issuing Bank an
issuance fee of $250 and a fronting fee, which shall accrue at the rate of 0.125% per annum 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 the 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 shall be payable in arrears on the last day of
March, June, September and December of each year and on the date on which the Commitments
terminate. Any other fees payable to the Issuing Bank pursuant to this paragraph shall be payable
within 10 days after demand. All participation fees and fronting 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) The Borrower agrees to pay to the Administrative Agent, for its own account, fees payable
in the amounts and at the times separately agreed upon in writing between the 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 the Issuing Bank, in the case of fees payable to it) for
distribution, in the case of commitment fees and participation fees, to the Lenders. Fees paid
shall not be refundable under any circumstances.

     Section 2.12 Interest. 

          (a) The Loans comprising each ABR Borrowing shall bear interest at the Alternate Base Rate,
but not to exceed the Highest Lawful Rate.

31

 

          (b) The Loans comprising each Eurodollar Borrowing shall bear interest at the Adjusted LIBO
Rate for the Interest Period in effect for such Borrowing plus the Applicable Margin, but not to
exceed the Highest Lawful Rate.

          (c) Notwithstanding the foregoing, if any principal of or interest on any Loan or any fee or
other amount payable by the 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, but not to exceed the Highest Lawful Rate.

          (d) Accrued interest on each Loan shall be payable in arrears on each Interest Payment Date
for such Loan and upon termination of the Commitments; provided that (i) interest accrued
pursuant to paragraph (c) of this Section shall be payable on demand, (ii) in the event of any
repayment or prepayment of any Loan (other than a prepayment of an ABR Loan prior to the end of
the Availability Period), 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.

          (e) 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.

     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; or

          (b) the Administrative Agent is advised by the Required Lenders that the Adjusted LIBO Rate
or the LIBO Rate, as applicable, 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;

then the Administrative Agent shall give notice thereof to the Borrower and the Lenders by
telephone or telecopy as promptly as practicable thereafter and, until the Administrative Agent
notifies the 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

32

 

continuation of any Borrowing as, a Eurodollar Borrowing shall be ineffective and (ii) if any
Borrowing Request requests a Eurodollar Borrowing, such Borrowing shall be made 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 the Issuing Banks; or

               (ii) impose on any Lender or the Issuing Banks 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 (excluding, in each case, Taxes, as to which Section 2.16 shall govern);

          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 the Issuing Banks 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
the Issuing Banks hereunder (whether of principal, interest or otherwise), then the Borrower will
pay to such Lender or the Issuing Banks, as the case may be, such additional amount or amounts as
will compensate such Lender or the Issuing Banks, as the case may be, for such additional costs
incurred or reduction suffered.

          (b) If any Lender or an Issuing Bank 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 the
Issuing Bank’s capital or on the capital of such Lender’s or the 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 the Issuing Bank, to a level below
that which such Lender or the Issuing Bank or such Lender’s or the Issuing Bank’s holding company
could have achieved but for such Change in Law (taking into consideration such Lender’s or the
Issuing Bank’s policies and the policies of such Lender’s or the Issuing Bank’s holding company
with respect to capital adequacy), then from time to time the Borrower will pay to such Lender or
the Issuing Bank, as the case may be, such additional amount or amounts as will compensate such
Lender or the Issuing Bank or such Lender’s or the Issuing Bank’s holding company for any such
reduction suffered.

          (c) A certificate of a Lender or the Issuing Bank setting forth in reasonable detail the
amount or amounts necessary to compensate such Lender or the Issuing Bank or its holding company,
as the case may be, as specified in paragraph (a) or (b) of this Section shall be delivered to the
Borrower. The Borrower shall pay to the Administrative Agent for the account of such Lender or
the Issuing Bank, as the case may be, the amount shown as due on any such certificate within 10
days after receipt thereof.

33

 

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

     Section 2.15 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 Eurodollar 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 the Borrower pursuant to Section
2.18, then, in any such event, the 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 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 pursuant to this Section in reasonable
detail shall be delivered to the Borrower. The 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 the Borrower hereunder shall
be made free and clear of and without deduction for any Indemnified Taxes or Other Taxes; provided
that if the 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, Lender, or Issuing Banks (as the case may be) receives an
amount equal to the sum it would have received had no such deductions been made, (ii) the Borrower
shall make such deductions and (iii) the Borrower shall pay the full amount deducted to the
relevant Governmental Authority in accordance with applicable law.

34

 

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

          (c) The Borrower shall indemnify the Administrative Agent, each Lender, and the Issuing Banks
within 10 days after written demand therefor, for the full amount of any Indemnified Taxes or
Other Taxes paid by the Administrative Agent, such Lender, or the Issuing Banks, as the case may
be (including Indemnified Taxes or Other Taxes imposed or asserted on or attributable to amounts
payable under this Section), and any penalties, interest and reasonable expenses arising therefrom
or with respect thereto, whether or not such Indemnified Taxes or Other Taxes were correctly or
legally imposed or asserted by the relevant Governmental Authority. A certificate as to the
amount of such payment or liability in reasonable detail shall be delivered to the Borrower by a
Lender or the Issuing Banks, or by the Administrative Agent on its own behalf or on behalf of a
Lender or the Issuing Banks.

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

          (f) Upon the Borrower’s written request, the Administrative Agent and each Lender shall use
reasonable efforts to make any filings necessary to obtain any refund, deduction or credit of any
Taxes or Other Taxes as to which the Borrower has indemnified it or with respect to which the
Borrower has paid additional amounts pursuant to this Section 2.16. If the Administrative Agent
or a Lender receives any material refund of any Taxes or Other Taxes as to which it has been
indemnified by the Borrower or with respect to which the Borrower has paid additional amounts
pursuant to this Section 2.16, it shall pay over such refund to the Borrower (but only to the
extent of indemnity payments made, or additional amounts paid, by the Borrower under this Section
2.16 with respect to the Taxes or Other Taxes giving rise to such refund), net of all reasonable
out-of-pocket expenses of the Administrative Agent or such Lender and without interest (other than
any interest paid by the relevant Governmental Authority with respect to such refund); provided,
that the Borrower, upon the request of the Administrative Agent or such Lender, agrees to repay
the amount paid over to the Borrower (plus any penalties, interest or other charges imposed by the
relevant Governmental Authority) to the Administrative Agent or such Lender in the event the
Administrative Agent or such Lender is required to repay such refund to such Governmental
Authority. This Section shall not be construed to require the Administrative Agent or any Lender
to make available its tax returns (or any other information relating to its taxes which it deems
confidential) to the Borrower or any other Person or to attempt to take any position to

35

 

obtain a
refund, deduction, or credit, which attempt would be inconsistent with any reporting position
otherwise taken by the Administrative Agent or such Lender on its applicable tax returns.

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

          (a) The Borrower shall make each payment required to be made by it hereunder (whether of
principal, interest, fees or reimbursement of LC Disbursements, or of amounts payable under
Section 2.14, 2.15 or 2.16, or otherwise) prior to 12:00 noon, New York City time, on the date
when due, in immediately available funds, without set-off or counterclaim. Any amounts received
after such time on any date may, in the discretion of the Administrative Agent, be deemed to have
been received on the next succeeding Business Day for purposes of calculating interest thereon.
All such payments shall be made to the Administrative Agent at its offices at 270 Park Avenue, New
York, New York, except payments to be made directly to the Issuing Banks as expressly provided
herein and except that payments pursuant to Section 9.03 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.

          (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 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 the 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

36

 

in any of its Loans or
participations in LC Disbursements to any assignee or participant, other than to the Borrower or
any Subsidiary or Affiliate thereof (as to which the provisions of this paragraph shall apply).
The Borrower consents to the foregoing and agrees, to the extent it may effectively do so under
applicable law, that any Lender acquiring a participation pursuant to the foregoing arrangements
may exercise against the Borrower rights of set-off and counterclaim with respect to such
participation as fully as if such Lender were a direct creditor of the Borrower in the amount of
such participation.

          (d) Unless the Administrative Agent shall have received notice from the Borrower prior to the
date on which any payment is due to the Administrative Agent for the account of the Lenders or the
Issuing Banks hereunder that the Borrower will not make such payment, the Administrative Agent
may assume that the Borrower has made such payment on such date in accordance herewith and may, in
reliance upon such assumption, distribute to the Lenders or the Issuing Banks, as the case may be,
the amount due. In such event, if the Borrower has not in fact made such payment, then each of
the Lenders or the Issuing Banks, as the case may be, severally agrees to repay to the
Administrative Agent forthwith on demand the amount so distributed to such Lender or Issuing Banks
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 2.05(d) or (e), 2.06(b) or 2.17(d), then the Administrative Agent may, in its discretion
(notwithstanding any contrary provision hereof), apply any amounts thereafter received by the
Administrative Agent for the account of such Lender to satisfy such Lender’s obligations under
such Sections until all such unsatisfied obligations are fully paid.

     Section 2.18 Mitigation Obligations; Replacement of Lenders. 

          (a) If any Lender requests compensation under Section 2.14, or if the 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.
The 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 the 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, then the Borrower may, at its sole expense and effort, upon notice to such Lender and
the Administrative Agent, require such Lender to assign and

37

 

delegate, without recourse (in
accordance with and subject to the restrictions contained in Section 9.04), all its interests,
rights and obligations under this Agreement to an assignee that shall assume such obligations
(which assignee may be another Lender, if a Lender accepts such assignment); provided that
(i) the Borrower shall have received the prior written consent of the Administrative Agent (and,
if a Commitment is being assigned, the Issuing Banks) which consent shall not unreasonably be
withheld, (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 the Borrower (in the case of all other
amounts) and (iii) 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. A Lender shall not be required to make
any such assignment and delegation if, prior thereto, as a result of a waiver by such Lender or
otherwise, the circumstances entitling the Borrower to require such assignment and delegation
cease to apply.

ARTICLE III

     The Borrower represents and warrants to the Lenders that:

     Section 3.05 Properties. Each of the Borrower and its Restricted Subsidiaries has
good title to, or valid leasehold interests in, all its real and personal property material to its
business, except for any failure, defect or other matter that could not, in the aggregate,

     Section 3.06 Litigation and Environmental Matters.

          (a) There are no actions, suits or proceedings by or before any arbitrator or Governmental
Authority pending against or, to the knowledge of the Borrower, threatened against or affecting

involve this Agreement or the Transactions.

          (b) Except for the Disclosed Matters and except with respect to any other matters that,
individually or in the aggregate, could not reasonably be expected to result in a Material Adverse

expected to occur, could reasonably be expected to result in a Material Adverse Effect. The
Borrower and each ERISA Affiliate has fulfilled its obligations under the minimum funding standards
of ERISA and the Code with respect to each Plan and is in compliance in all material respects with
the presently applicable provisions of ERISA and the Code with respect to each Plan. Neither the
Borrower nor any ERISA Affiliate has (a) sought a waiver of the minimum funding standard under
Section 412 of the Code in respect of any Plan, (b) failed to make any contribution or payment to

          (k) one or more judgments for the payment of money in an aggregate amount in excess of
$50,000,000 shall be rendered against the Borrower, any Restricted Subsidiary or any combination
thereof and the same shall remain undischarged for a period of 30 consecutive days during which
execution shall not be effectively stayed, or any action shall be legally taken by a judgment
creditor to attach or levy upon any material domestic assets of the Borrower or any Restricted
Subsidiary to enforce any such judgment;

          (l) an ERISA Event shall have occurred that, in the opinion of the Required Lenders, when
taken together with all other ERISA Events that have occurred, could reasonably be expected to
result in a Material Adverse Effect or result in liability of the Borrower and its Subsidiaries in
an aggregate amount exceeding $50,000,000 for all periods;

          (m) a Change in Control shall occur;

          (n) any provision of any Subsidiary Guaranty for any reason is not a legal, valid, binding
and enforceable obligation of the Subsidiary Guarantor shown as being a party thereto or any
Subsidiary or the Borrower shall so state in writing; provided that an Event of Default
shall not exist under this clause (n) unless the Subsidiary Guarantors implicated hereby consist
of Material Subsidiaries; or

          (o) the Borrower or any other Person shall petition or apply for or obtain any order
restricting payment by an Issuing Bank under any Letter of Credit or extending the liability of an
Issuing Bank under any Letter of Credit beyond the expiration date stated therein;

then, and in every such event (other than an event with respect to an Obligor described in clause
(h) or (i) of this Article), and at any time thereafter during the continuance of such event, the
Administrative Agent may, and at the request of the Required Lenders shall, by notice to the
Borrower, take either or both of the following actions, at the same or different times: (i)
terminate the Commitments, and thereupon the Commitments shall terminate immediately, and (ii)
declare the Loans then outstanding to be due and payable in whole (or in part, in which case any
principal not so declared to be due and payable may thereafter be declared to be due and payable),
and thereupon the principal of the Loans so declared to be due and payable, together with accrued
interest thereon and all fees and other obligations of the Borrower accrued hereunder, shall become
due and payable immediately, without presentment, demand, protest or

53

 

other notice of any kind, all of which are hereby waived by the Borrower; and in case of any event
with respect to an Obligor described in clause (h) or (i) of this Article, the Commitments shall
automatically terminate and the principal of the Loans then outstanding, together with accrued
interest thereon and all fees and other obligations of the Borrower accrued hereunder, shall
automatically become due and payable, without presentment, demand, protest or other notice of any
kind, all of which are hereby waived by the Borrower.

ARTICLE VIII

THE ADMINISTRATIVE AGENT

     Section 8.01 Administrative Agent. Each of the Lenders and the Issuing Banks hereby
irrevocably appoints the Administrative Agent as its agent and authorizes the Administrative Agent
to take such actions on its behalf and to exercise such powers as are delegated to the
Administrative Agent by the terms hereof, together with such actions and powers as are reasonably
incidental thereto.

     The bank serving as the Administrative 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 the
Administrative Agent, and such bank and its Affiliates may accept deposits from, lend money to and
generally engage in any kind of business with the Borrower or any Subsidiary or other Affiliate
thereof as if it were not the Administrative Agent hereunder.

     The Administrative Agent shall not have any duties or obligations except those expressly set
forth herein. Without limiting the generality of the foregoing, (a) the Administrative Agent shall
not be subject to any fiduciary or other implied duties, regardless of whether a Default has
occurred and is continuing, (b) the Administrative 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 the Administrative Agent is required to exercise in writing as
directed by the Required Lenders (or such other number or percentage of the Lenders as shall be
necessary under the circumstances as provided in Section 9.02), and (c) except as expressly set
forth herein, the Administrative Agent shall not have any duty to disclose, and shall not be liable
for the failure to disclose, any information relating to the Borrower or any of its Subsidiaries
that is communicated to or obtained by the bank serving as Administrative Agent or any of its
Affiliates in any capacity. The Administrative 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
9.02) or in the absence of its own gross negligence or willful misconduct. The Administrative
Agent shall be deemed not to have knowledge of any Default unless and until written notice thereof
is given to the Administrative Agent by the Borrower or a Lender, and the Administrative 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 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 the Administrative Agent.

54

 

     The Administrative Agent 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 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 may consult with legal counsel (who may be counsel for the
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.

     The Administrative Agent may perform any and all its duties and exercise its rights and powers
by or through any one or more sub-agents appointed by the Administrative Agent. The Administrative
Agent and any such sub-agent may perform any and all 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 the Administrative 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 Administrative 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 the Borrower. Upon any such resignation, the Required Lenders shall have the
right, in consultation with the Borrower, to appoint a successor. If no successor shall have been
so appointed by the Required Lenders 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. 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 the Borrower to a
successor Administrative Agent shall be the same as those payable to its predecessor unless
otherwise agreed between the Borrower and such successor. After the Administrative Agent’s
resignation hereunder, the provisions of this Article and Section 9.03 shall continue in effect for
the benefit of such retiring Administrative Agent, its sub-agents and their respective Related
Parties in respect of any actions taken or omitted to be taken by any of them while it was acting
as Administrative Agent.

     Each Lender acknowledges that it has, independently and without reliance upon the
Administrative Agent, any Issuing Bank or any 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 the
Administrative Agent, any Issuing Bank or any 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.

55

 

     Each Lender,
ratably in accordance with its respective Applicable Percentage,
shall indemnify the Administrative Agent, sub-agents appointed by the Administrative Agent pursuant
to this Article VIII and each Related Party of the Administrative Agent and such sub-agents (each
such Person being called an “Agent Indemnitee”) against, and hold each Agent Indemnitee harmless
from, any and all losses, claims, damages, liabilities and related expenses, including the fees,
charges and disbursements of any counsel for any Agent Indemnitee, incurred by or asserted against
any Agent Indemnitee to the extent (i) that such Agent Indemnitee is entitled to indemnification
from the Borrower pursuant to Section 9.03(b) and (ii) either (1) such Agent Indemnitee is not
promptly and indefeasibly paid the amount of such indemnification by the Borrower or (2) any such
payment is rescinded or must otherwise be returned by such Agent Indemnitee upon the insolvency,
bankruptcy or reorganization of any Person or otherwise. It is the express intent of the parties
hereto that each Agent Indemnitee shall, to the extent contemplated in Section 9.03 be indemnified
for its own ordinary, sole or contributory negligence. Payment by any Lender pursuant to this
Article VIII shall not relieve the Borrower of its obligations under Section 9.03, and each Lender
making a payment under this paragraph shall be entitled to receive from each Agent Indemnitee such
Lender’s ratable share of any amount indefeasibly recovered by such Agent Indemnitee from the
Borrower on account of the previously unpaid indemnification pursuant to Section 9.03(b) that
required such payment by such Lender under this paragraph, in each case without interest.

     Section 8.02 The Arranger, Sole Bookrunner, Syndication Agent and Documentation
Agents. The Arranger, Sole Bookrunner, Syndication Agent and Documentation Agents shall have
no duties, responsibilities or liabilities under this Agreement and the other Loan Documents other
than their duties, responsibilities and liabilities in their capacity as Lenders (or as an Issuing
Bank, if applicable) hereunder.

ARTICLE IX

     Section 9.01 Notices. (a) Except in the case of notices and other communications
expressly permitted to be given by telephone (and subject to paragraph (b) below), all notices and
other communications provided for herein shall be in writing and shall be delivered by hand or
overnight courier service, mailed by certified or registered mail or sent by telecopy, as follows:

    (ii) if to the Administrative Agent, to JPMorgan Chase Bank, N.A., Loan and Agency

    (iv) if to any other Lender, to it at its address (or telecopy number) set forth in its
Administrative Questionnaire.

          (b) Notices and communications to the Lenders hereunder may be delivered or furnished by
electronic communications pursuant to procedures approved by the Administrative Agent; provided
that the foregoing shall not apply to notices pursuant to Article II unless otherwise agreed by
the Administrative Agent and the applicable Lender. The Administrative Agent or the Borrower
may, in its discretion, agree to accept notices and other communications to it hereunder by
electronic communications pursuant to procedures approved by it; provided that approval of such
procedures may be limited to particular notices or communications.

          (c) Any party hereto may change its address or telecopy number for notices and other
communications hereunder by notice to the other parties hereto, or, in the case of any Lender, to
the Administrative Agent and the Borrower. All notices and other communications given to any
party hereto in accordance with the provisions of this Agreement shall be deemed to have been
given on the date of receipt.

     Section 9.02 Waivers; Amendments. 

          (a) No failure or delay by the Administrative Agent, the Issuing Banks 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 consent to any departure by
the Borrower therefrom shall in any event be effective unless the same shall be permitted by
paragraph (b) of this Section, and then such waiver or consent shall be effective only in the
specific instance and for the purpose for which given. Without limiting the generality of the
foregoing, 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 Lender or the Issuing
Banks may have had notice or knowledge of such Default at the time.

          (b) Neither this Agreement, any provision hereof, nor any provisions of the Subsidiary
Guaranties may be waived, amended or modified except pursuant to an agreement or agreements in
writing entered into by the Borrower and the Required Lenders or by the Borrower and the
Administrative Agent with the consent of the Required Lenders; provided that no
such agreement shall (i) increase or extend the Commitment of any Lender without the written
consent of such Lender, (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

57

 

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 Section 2.17(b) or (c), or Section 2.08(c) in a manner that
would alter the pro rata treatment of Lenders or 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 specifying the number or
percentage of Lenders required to waive, amend or modify any rights hereunder or make any
determination or grant any consent hereunder, without the written consent of each Lender;
provided further that no such agreement shall amend, modify or otherwise affect
the rights or duties of the Administrative Agent or the Issuing Banks hereunder without the prior
written consent of the Administrative Agent or the Issuing Banks, as the case may be.

     Section 9.03 Expenses; Indemnity; Damage Waiver. 

          (a) The Borrower shall pay (i) all reasonable out-of-pocket expenses incurred by the
Administrative Agent and the Arranger and their Affiliates, including the reasonable fees, charges
and disbursements of counsel for the Administrative Agent, in connection with the syndication of
the credit facilities provided for herein, the preparation and administration of this Agreement
and the Subsidiary Guaranties 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 the Issuing Banks 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 Administrative Agent, the Issuing
Banks or any Lender, including the reasonable fees, charges and disbursements of any counsel for
the Administrative Agent, the Issuing Banks or any Lender, in connection with the enforcement or
protection of its rights in connection with this Agreement and the Subsidiary Guaranties,
including its rights under this Section, or in connection with the Loans made or Letters of Credit
issued hereunder, including all such reasonable out-of-pocket expenses incurred during any
workout, restructuring or negotiations in respect of such Loans or Letters of Credit.

          (b) The Borrower shall indemnify the Administrative Agent, each Issuing Bank, each Lender and
each Related Party of the Administrative Agent, any Issuing Bank or any Lender (each such Person
being called an “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 use of the
proceeds therefrom (including any refusal by the Issuing Banks to honor any 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 the Borrower or any of its
Subsidiaries, or any Environmental Liability

58

 

related in any way to the 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 any Indemnitee is a
party thereto; and SUCH INDEMNITY SHALL EXTEND TO EACH INDEMNITEE NOTWITHSTANDING THE SOLE OR
CONCURRENT NEGLIGENCE OF EVERY KIND OR CHARACTER WHATSOEVER, WHETHER ACTIVE OR PASSIVE, WHETHER AN
AFFIRMATIVE ACT OR AN OMISSION, INCLUDING WITHOUT LIMITATION, ALL TYPES OF NEGLIGENT CONDUCT
IDENTIFIED IN THE RESTATEMENT (SECOND) OF TORTS OF ONE OR MORE OF THE INDEMNITEES OR ANY STRICT
LIABILITY IMPOSED WITHOUT FAULT ON ANY ONE OR MORE OF THE INDEMNITEES; PROVIDED THAT SUCH
INDEMNITY SHALL NOT, AS TO ANY INDEMNITEE, BE AVAILABLE TO THE EXTENT THAT SUCH LOSSES, CLAIMS,
DAMAGES, LIABILITIES OR RELATED EXPENSES ARE DETERMINED BY A COURT OF COMPETENT JURISDICTION BY
FINAL AND NONAPPEALABLE JUDGMENT TO HAVE RESULTED FROM THE GROSS NEGLIGENCE OR WILLFUL MISCONDUCT
OF SUCH INDEMNITEE.

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

          (d) To the extent permitted by applicable law, the Borrower shall not assert, and hereby
waives, any claim against any Indemnitee, 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, any Loan or Letter of Credit or the use of the proceeds thereof.

          (e) All amounts due under this Section shall be payable promptly after written demand
therefor.

     Section 9.04 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
Affiliates of the Issuing Banks that issue any Letters of Credit), except that (i) the 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 the Borrower without
such consent shall be null and void) and (ii) no Lender may assign or otherwise transfer its
rights or obligations hereunder except in accordance with this Section. Nothing in this
Agreement, expressed or implied, shall be construed to confer upon any Person

59

 

(other than the parties hereto, their respective successors and assigns permitted hereby
(including any Affiliates of the Issuing Banks that issue any Letters of Credit), Participants (to
the extent provided in paragraph (c) of this Section) 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) (i) Subject to the conditions set forth in paragraph (b)(ii) below, any Lender may
assign to one or more assignees all or a portion of its rights and obligations under this
Agreement (including all or a portion of its Commitment and the Loans at the time owing to it)
with the prior written consent (such consent not to be unreasonably withheld or delayed) of:

                    (A) the Borrower, provided that no consent of the Borrower shall be required for an
assignment to a Lender, an Affiliate of a Lender, an Approved Fund or, if an Event of Default has
occurred and is continuing, any other assignee; and

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

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

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

                    (B) each partial assignment shall be made as an assignment of a proportionate part of all the
assigning Lender’s rights and obligations under this Agreement, provided that this clause
shall not be construed to prohibit the assignment of a proportionate part of all the assigning
Lender’s rights and obligations in respect of its Commitments or Loans;

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

                    (D) the assignee, if it shall not be a Lender, shall deliver to the Administrative Agent an
Administrative Questionnaire and comply with the requirements of Section 2.16(e).

60

 

          For the purposes of this Section 9.04(b), the term “Approved Fund” has the following
meaning:

          “Approved Fund” means any Person (other than a natural person) that is engaged in
making, purchasing, holding or investing in bank loans and similar extensions of credit in the
ordinary course of its business and that is administered, managed or underwritten by (a) a Lender,
(b) an Affiliate of a Lender or (c) an entity or an Affiliate of an entity that administers or
manages a Lender .

                    (iii) Subject to acceptance and recording thereof pursuant to paragraph (b)(iv) of this
Section, from and after the effective date specified in each Assignment and Assumption the assignee
thereunder shall be a party hereto and, to the extent of the interest assigned by such Assignment
and Assumption, have the rights and obligations of a Lender under this Agreement, and the assigning
Lender thereunder shall, to the extent of the interest assigned by such Assignment and Assumption,
be released from its obligations under this Agreement (and, in the case of an Assignment and
Assumption covering all of the assigning Lender’s rights and obligations under this Agreement, such
Lender shall cease to be a party hereto but shall continue to be entitled to the benefits of
Sections 2.14, 2.15, 2.16 and 9.03). Any assignment or transfer by a Lender of rights or
obligations under this Agreement that does not comply with this Section 9.04 shall be treated for
purposes of this Agreement as a sale by such Lender of a participation in such rights and
obligations in accordance with paragraph (c) of this Section.

                    (iv) The Administrative Agent, acting for this purpose as an agent of the Borrower, shall
maintain at one of its offices a copy of each Assignment and Assumption delivered to it and a
register for the recordation of the names and addresses of the Lenders, and the Commitment of, and
principal amount of the Loans and LC Disbursements owing to, each Lender pursuant to the terms
hereof from time to time (the “Register”). The entries in the Register shall be
conclusive, and the 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 the Borrower, the Issuing Banks and any Lender, at any
reasonable time and from time to time upon reasonable prior notice.

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

          (c) (i) Any Lender may, without the consent of the Borrower, the Administrative Agent or the
Issuing Banks, 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

61

 

that (A) such Lender’s obligations under this Agreement shall remain unchanged, (B) such
Lender shall remain solely responsible to the other parties hereto for the performance of such
obligations and (C) the Borrower, the Administrative Agent, the Issuing Banks and the other
Lenders shall continue to deal solely and directly with such Lender in connection with such
Lender’s rights and obligations under this Agreement. Any agreement or instrument pursuant to
which a Lender sells such a participation shall provide that such Lender shall retain the sole
right to enforce this Agreement and to approve any amendment, modification or waiver of any
provision of this Agreement; provided that such agreement or instrument may provide that
such Lender will not, without the consent of the Participant, agree to any amendment, modification
or waiver described in the first proviso to Section 9.02(b) that affects such Participant.
Subject to paragraph (c)(ii) of this Section, the 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.

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

          (d) Any Lender may at any time pledge or assign a security interest in all or any portion of
its rights under this Agreement to secure obligations of such Lender, including without limitation
any pledge or assignment to secure obligations to a Federal Reserve Bank, and this Section shall
not apply to any such pledge or assignment of a security interest; provided that no such
pledge or assignment of a security interest shall release a Lender from any of its obligations
hereunder or substitute any such pledgee or assignee for such Lender as a party hereto.

     Section 9.05 Survival. All covenants, agreements, representations and warranties made
by the 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, the Issuing Banks 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 and 9.03
and Article VIII shall survive and remain in full force and effect regardless of the consummation
of the transactions contemplated hereby, the repayment of the Loans, the expiration or termination
of the Letters of Credit and the Commitments or the termination of this Agreement or any provision
hereof.

62

 

     Section 9.06 Counterparts; Integration; Effectiveness. This Agreement may be executed
in counterparts (and by different parties hereto on different counterparts), each of which shall
constitute an original, but all of which when taken together shall constitute a single contract.
Except as provided in Section 4.01, 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. This Agreement, the other Loan Documents 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 thereof and supersede any and all previous
agreements and understandings, oral or written, relating to the subject matter hereof and thereof.
THIS AGREEMENT, SUCH SEPARATE LETTER AGREEMENTS AND THE OTHER LOAN DOCUMENTS REPRESENT THE FINAL
AGREEMENT AMONG THE PARTIES HERETO AND THERETO AND MAY NOT BE CONTRADICTED BY EVIDENCE OF PRIOR,
CONTEMPORANEOUS OR SUBSEQUENT ORAL AGREEMENTS OF THE PARTIES. THERE ARE NO UNWRITTEN ORAL
AGREEMENTS BETWEEN THE PARTIES.

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

     Section 9.08 Governing Law; Jurisdiction; Consent to Service of Process. 

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

          (b) The 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 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 Administrative Agent, any Issuing Bank or any Lender may otherwise have to bring any
action or proceeding relating to this Agreement against the Borrower or its properties in the
courts of any jurisdiction.

          (c) The 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

63

 

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 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 in the
manner provided for notices in Section 9.01. Nothing in this Agreement will affect the right of
any party to this Agreement to serve process in any other manner permitted by law.

     Section 9.09 WAIVER OF JURY TRIAL. EACH PARTY HEREBY (i) IRREVOCABLY
AND UNCONDITIONALLY WAIVES, TO THE FULLEST EXTENT PERMITTED BY LAW, TRIAL BY JURY IN ANY LEGAL
ACTION OR PROCEEDING RELATING TO THIS AGREEMENT OR ANY OTHER DOCUMENT RELATED TO THIS AGREEMENT AND
FOR ANY COUNTERCLAIM THEREIN; (ii) IRREVOCABLY AND UNCONDITIONALLY WAIVES, TO THE MAXIMUM EXTENT
NOT PROHIBITED BY LAW, ANY RIGHT IT MAY HAVE TO CLAIM OR RECOVER IN ANY SUCH LITIGATION ANY
SPECIAL, EXEMPLARY, PUNITIVE OR CONSEQUENTIAL DAMAGES, OR DAMAGES OTHER THAN, OR IN ADDITION TO,
ACTUAL DAMAGES; (iii) CERTIFIES THAT NO PARTY HERETO NOR ANY REPRESENTATIVE OR AGENT OR COUNSEL FOR
ANY PARTY HERETO HAS REPRESENTED, EXPRESSLY OR OTHERWISE, OR IMPLIED THAT SUCH PARTY WOULD NOT, IN
THE EVENT OF LITIGATION, SEEK TO ENFORCE THE FOREGOING WAIVERS, AND (iv) ACKNOWLEDGES THAT IT HAS
BEEN INDUCED TO ENTER INTO THIS AGREEMENT, THE LOAN DOCUMENTS AND THE TRANSACTIONS CONTEMPLATED
HEREBY AND THEREBY BY, AMONG OTHER THINGS, THE MUTUAL WAIVERS AND CERTIFICATIONS CONTAINED IN THIS
SECTION 9.09.

     Section 9.10 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 9.11 Confidentiality. Each of the Administrative Agent, 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 and legal counsel (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 authority or
any self-regulatory body claiming to have authority, (c) to the extent required by applicable laws
or regulations or by any subpoena or similar legal process or authority, (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 (i) any
assignee of or Participant in, or any prospective assignee of or Participant in, any of its rights
or obligations under this Agreement, (ii) any actual or prospective counterparty (or its advisors)
to any swap or derivative transaction relating to the Borrower and its obligations, (iii) to its
advisors (other than its accountants and legal counsel), (iv) to an investor or prospective
investor in an Approved Fund that also agrees that Information shall be used solely for the

64

 

purpose of evaluating an investment in such Approved Fund, (v) to a trustee, collateral
manager, servicer, backup servicer, noteholder or secured party in an Approved Fund in connection
with the administration, servicing and reporting on the assets serving as collateral for an
Approved Fund, or (vi) to a nationally recognized rating agency that requires access to information
regarding the Borrower, the Loans and Loan Documents in connection with ratings issued with respect
to an Approved Fund, (g) with the consent of the Borrower or (h) to the extent such
Information becomes publicly available other than as a result of a breach of this Section. For the
purposes of this Section, “Information” means all information received from the Borrower relating
to the Borrower or its business, other than any such information that is available to the
Administrative Agent, the Issuing Banks or any Lender on a nonconfidential basis prior to
disclosure by the Borrower; provided that, in the case of information received from the Borrower
after the date hereof, such information is clearly identified at the time of delivery as
confidential. Any Person required to maintain the confidentiality of Information as provided in
this Section shall be considered to have complied with its obligation to do so if such Person has
exercised the same degree of care to maintain the confidentiality of such Information as such
Person would accord to its own confidential information.

     Section 9.12 Interest Rate Limitation. Notwithstanding anything herein to the
contrary, if at any time the interest rate applicable to any Loan, together with all fees, charges
and other amounts which are treated as interest on such Loan under applicable law (collectively the
“Charges”), shall exceed the maximum lawful rate (the “Maximum Rate”) which may be contracted for,
charged, taken, received or reserved by the Lender holding such Loan in accordance with applicable
law, the rate of interest payable in respect of such Loan hereunder, together with all Charges
payable in respect thereof, shall be limited to the Maximum Rate and, to the extent lawful, the
interest and Charges that would have been payable in respect of such Loan but were not payable as a
result of the operation of this Section shall be cumulated and the interest and Charges payable to
such Lender in respect of other Loans or periods shall be increased (but not above the Maximum Rate
therefor) until such cumulated amount, together with interest thereon at the Federal Funds
Effective Rate to the date of repayment, shall have been received by such Lender.

     Section 9.13 Right of Setoff. If an Event of Default shall have occurred and be
continuing, 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 and other obligations at any
time owing by such Lender or Affiliate to or for the credit or the account of the Borrower against
any of and all the obligations of the 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 9.14 USA Patriot Act Notice. Each Lender hereby notifies the Borrower that
pursuant to the requirements of the USA Patriot Act (Title III of Pub. L. 107-56 (signed into law
October 26, 2001)) (the “Act”), it is required to obtain, verify and record information that
identifies the Borrower, which information includes the name and address of the Borrower and

65

 

other information that will allow such Lender to identify the Borrower in accordance with the
Act.

          This Assignment and Assumption (the “Assignment and Assumption”) is dated as of the
Effective Date set forth below and is entered into by and between [Insert name of Assignor] (the
“Assignor”) and [Insert name of Assignee] (the “Assignee”). Capitalized terms used
but not defined herein shall have the meanings given to them in the Credit Agreement identified
below [, as amended] (the “Credit Agreement”), receipt of a copy of which is hereby
acknowledged by the Assignee, it being agreed that as used herein and in Annex 1 the term
“Effective Date” shall have the meaning set forth below and not the meaning set forth in the Credit
Agreement. The Standard Terms and Conditions set forth in Annex 1 attached hereto are hereby
agreed to and incorporated herein by reference and made a part of this Assignment and Assumption as
if set forth herein in full.

          For an agreed consideration, the Assignor hereby irrevocably sells and assigns to the
Assignee, and the Assignee hereby irrevocably purchases and assumes from the Assignor, subject to
and in accordance with the Standard Terms and Conditions and the Credit Agreement, as of the
Effective Date inserted by the Administrative Agent as contemplated below (i) all of the Assignor’s
rights and obligations (including, without limitation, all liabilities and duties under Sections
2.05(d) and 2.05(e)) in its capacity as a Lender under the Credit Agreement and any other documents
or instruments delivered pursuant thereto to the extent related to the amount and percentage
interest identified below of all of such outstanding rights and obligations of the Assignor under
the Credit Agreement and (ii) to the extent permitted to be assigned under applicable law, all
claims, suits, causes of action and any other right of the Assignor (in its capacity as a Lender)
against any Person, whether known or unknown, arising under or in connection with the Credit
Agreement, any other documents or instruments delivered pursuant thereto or the loan transactions
governed thereby or in any way based on or related to any of the foregoing, including contract
claims, tort claims, malpractice claims, statutory claims and all other claims at law or in equity
related to the rights and obligations sold and assigned pursuant to clause (i) above (the rights
and obligations sold and assigned pursuant to clauses (i) and (ii) above being referred to herein
collectively as the “Assigned Interest”). Such sale and assignment is without recourse to
the Assignor and, except as expressly provided in this Assignment and Assumption, without
representation or warranty by the Assignor.

FORM OF

SUBSIDIARY GUARANTY

     GUARANTY
dated as of
                 , 200___made by the undersigned (the
“Guarantor”) in favor of the Lenders, the Issuing Banks and the Administrative Agent, as
those terms are defined in the Credit Agreement dated as of [___], 2005 among JPMorgan Chase
Bank, N.A., as Administrative Agent and as Issuing Bank, Newfield Exploration Company, a Delaware
corporation (the “Borrower”), and the Lenders party thereto [as amended] (the “Credit Agreement”;
terms defined therein and not defined herein are used herein as therein defined).

     PRELIMINARY STATEMENTS: The Credit Agreement provides for Loans to, and Letters of Credit for
the account of, the Borrower and requires this Guaranty be executed by the Guarantor on the
circumstances set forth therein. The Guarantor a Restricted Subsidiary and is financially
interested in the affairs of the Borrower.

     THEREFORE, in order to induce the Lenders, the Issuing Banks and the Administrative Agent
(together the “Beneficiaries” and each a “Beneficiary”) to extend credit or give financial
accommodation under or perform duties under the Credit Agreement and to comply with the terms
thereof, the Guarantor agrees as follows:

     Section 1. Guaranty of Payment. The Guarantor unconditionally and irrevocably
guarantees to the Beneficiaries the punctual payment of all Obligations now owing or which may in
the future be owing, when the same are due and payable, whether on demand, at stated maturity, by
acceleration or otherwise, and whether for principal, interest, Letter of Credit reimbursement
obligations, fees, expenses, indemnification or otherwise (all of the foregoing sums being the
“Liabilities”). The Liabilities include, without limitation, interest accruing after the
commencement of a proceeding under bankruptcy, insolvency or similar laws of any jurisdiction at
the rate or rates provided in the Loan Documents. This Guaranty is a guaranty of payment and not
of collection only. The Beneficiaries shall not be required to exhaust any right or remedy or take
any action against the Borrower or any other Person or any collateral. The Guarantor agrees that,
as between the Guarantor and the Beneficiaries, the Liabilities may be declared to be due and
payable for the purposes of this Guaranty notwithstanding any stay, injunction or other prohibition
which may prevent, delay or vitiate any declaration as regards the Borrower and that in the event
of a declaration or attempted declaration, the Liabilities shall immediately become due and payable
by the Guarantor for the purposes of this Guaranty.

     Section 2. Guaranty Absolute. The Guarantor guarantees that the Liabilities shall be
paid strictly in accordance with the terms of the Loan Documents. The liability of the Guarantor
under this Guaranty is absolute and unconditional irrespective of: (a) any change in the time,
manner or place of payment of, or in any other term of, all or any of the Loan Documents or
Liabilities, or any other amendment or waiver of or any consent to departure from any of the terms
of any Loan Document or Liability, including any increase or decrease in the rate of interest
thereon; (b) any release or amendment or waiver of, or consent to departure from, any other
guaranty or support document, or any exchange, release or non-perfection of any collateral, for all
or any of the Loan

Exhibit D - 1

 

Documents or Liabilities; (c) any present or future law, regulation or order of any jurisdiction
(whether of right or in fact) or of any agency thereof purporting to reduce, amend, restructure or
otherwise affect any term of any Loan Document or Liability; (d) without being limited by the
foregoing, any lack of validity or enforceability of any Loan Document or Liability; and (e) any
other setoff, defense or counterclaim whatsoever (in any case, whether based on contract, tort or
any other theory) with respect to the Loan Documents or the transactions contemplated thereby which
might constitute a legal or equitable defense available to, or discharge of, the Borrower or a
guarantor.

     Section 3. Guaranty Irrevocable. This Guaranty is a continuing guaranty of the
payment of all Liabilities now or hereafter existing and shall remain in full force and effect
until payment in full of all Liabilities and other amounts payable under this Guaranty and
termination of all Letters of Credit and the Commitments and until the Credit Agreement is no
longer in effect.

     Section 4. Reinstatement. This Guaranty shall continue to be effective or be
reinstated, as the case may be, if at any time any payment of any of the Liabilities is rescinded
or must otherwise be returned by any Beneficiary on the insolvency, bankruptcy or reorganization of
the Borrower or any Subsidiary or otherwise, all as though the payment had not been made.

     Section 5. Subrogation; Contribution. The Guarantor shall not exercise any rights
which it may acquire by way of subrogation or contribution, by any payment made under this Guaranty
or otherwise, until all the Liabilities have been paid in full, all Letters of Credit and
Commitments have been terminated, and the Credit Agreement is no longer in effect. If any amount
is paid to the Guarantor on account of subrogation or contribution rights, the amount shall be held
in trust for the benefit of the Beneficiaries and shall be promptly paid to the Administrative
Agent to be credited and applied to the Liabilities, whether matured or unmatured or absolute or
contingent, in accordance with the terms of the Credit Agreement.

     Section 6. Subordination. Without limiting the Beneficiaries’ rights under any other
agreement, any liabilities owed by the Borrower to the Guarantor in connection with any extension
of credit or financial accommodation by the Guarantor to or for the account of the Borrower,
including but not limited to interest accruing at the agreed contract rate after the commencement
of a bankruptcy or similar proceeding, are hereby subordinated to the Liabilities, and such
liabilities of the Borrower to the Guarantor, if the Required Lenders so request, shall be
collected, enforced and received by the Guarantor as trustee for the Beneficiaries and shall be
paid over to the Administrative Agent on account of the Liabilities but without reducing or
affecting in any manner the liability of the Guarantor under the other provisions of this Guaranty.

     Section 7. Payments Generally. All payments by the Guarantor shall be made in
dollars, in the manner and at the place required by the Credit Agreement.

     Section 8. Certain Taxes. The Guarantor further agrees that all payments to be made
hereunder shall be made without setoff or counterclaim and free and clear of, and without deduction
for, any taxes, levies, imposts, duties, charges, fees, deductions, withholdings or restrictions or
conditions of any nature whatsoever now or hereafter imposed, levied, collected, withheld or
assessed by any country or by any political subdivision or taxing authority thereof or

Exhibit D - 2

 

therein (“Taxes”). If any Taxes are required to be withheld from any amounts payable
hereunder, the amounts so payable shall be increased to the extent necessary to yield (after
payment of all Taxes) the amounts payable hereunder in the full amounts so to be paid. Whenever
any Tax is paid by the Guarantor, as promptly as possible thereafter, the Guarantor shall send the
Administrative Agent an official receipt showing payment thereof, together with such additional
documentary evidence as may be required from time to time by the Administrative Agent.

     Section 9. Representations and Warranties. The Guarantor represents and warrants
that: (a) this Guaranty (i) has been authorized by all necessary action; (ii) does not violate any
agreement, instrument, law, regulation or order applicable to the Guarantor; (iii) does not require
the consent or approval of any Person or entity, including but not limited to any Governmental
Authority, or any filing or registration of any kind; and (iv) is the legal, valid and binding
obligation of the Guarantor enforceable against the Guarantor in accordance with its terms, except
to the extent that enforcement may be limited by applicable bankruptcy, insolvency and other
similar laws affecting creditors’ rights generally; and (b) in executing and delivering this
Guaranty, the Guarantor has (i) without reliance on any Beneficiary or any information received
from any Beneficiary and based upon such documents and information it deems appropriate, made an
independent investigation of the transactions contemplated hereby and the Borrower, the Borrower’s
business, assets, operations, prospects and condition, financial or otherwise, and any
circumstances which may bear upon such transactions, the Borrower or the obligations and risks
undertaken herein with respect to the Liabilities; (ii) adequate means to obtain from the Borrower
on a continuing basis information concerning the Borrower; (iii) full and complete access to the
Loan Documents and any other documents executed in connection with the Loan Documents; and (iv) not
relied and will not rely upon any representations or warranties of any Beneficiary or any acts
heretofore or hereafter taken by any Beneficiary (including but not limited to any review by any
Beneficiary of the affairs of the Borrower).

     Section 10. Remedies Generally. The remedies provided in this Guaranty are cumulative
and not exclusive of any remedies provided by law.

     Section 11. Setoff. The Guarantor agrees that, in addition to (and without
limitation of) any right of setoff, banker’s lien or counterclaim any Beneficiary may otherwise
have, each Beneficiary shall be entitled, at its option, to offset balances (general or special,
time or demand, provisional or final) held by it for the account of the Guarantor at any of such
Beneficiary’s offices, in dollars or in any other currency, against any amount payable by the
Guarantor under this Guaranty which is not paid when due (regardless of whether such balances are
then due to the Guarantor), in which case it shall promptly notify the Guarantor thereof;
provided that the failure to give such notice shall not affect the validity thereof.

     Section 12. Formalities. The Guarantor waives presentment, notice of dishonor,
protest, notice of acceptance of this Guaranty or incurrence of any Liability and any other
formality with respect to any of the Liabilities or this Guaranty.

     Section 13. Amendments and Waivers. No amendment or waiver of any provision of this
Guaranty, nor consent to any departure by the Guarantor therefrom, shall be effective unless it is
in writing and signed by the Lenders, and then the waiver or consent shall be effective only in

Exhibit D - 3

 

the specific instance and for the specific purpose for which given. No failure on the part of any
Beneficiary to exercise, and no delay in exercising, any right under this Guaranty shall operate as
a waiver or preclude any other or further exercise thereof or the exercise of any other right.

     Section 14. Expenses. The Guarantor shall reimburse each Beneficiary on demand for
all costs, expenses and charges (including without limitation fees and charges of external legal
counsel for such Beneficiary and costs allocated by its internal legal department) incurred by such
Beneficiary in connection with the performance or enforcement of this Guaranty. The obligations of
the Guarantor under this Section shall survive the termination of this Guaranty.

     Section 15. Assignment. This Guaranty shall be binding on, and shall inure to the
benefit of the Guarantor, each Beneficiary and their respective successors and assigns;
provided that the Guarantor may not assign or transfer its rights or obligations under this
Guaranty. Without limiting the generality of the foregoing: (a) the obligations of the Guarantor
under this Guaranty shall continue in full force and effect and shall be binding on any successor
partnership and on previous partners if the Guarantor is a partnership, regardless of any change in
the partnership; and (b) each Beneficiary may assign, sell participations in or otherwise transfer
its rights under the Loan Documents to any other Person in accordance with the Credit Agreement,
and the other Person shall then become vested with all the rights granted to such Beneficiary in
this Guaranty to the extent of such assignment, participation or transfer.

     Section 16. Captions. The headings and captions in this Guaranty are for convenience
only and shall not affect the interpretation or construction of this Guaranty.

     Section 17. Governing Law; Jurisdiction; Consent to Service of Process. (e) This
Guaranty shall be construed in accordance with and governed by the law of the State of New York.

          (b) The Guarantor 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 Guaranty, 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 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 Guaranty shall affect any right
that the Administrative Agent, any Issuing Bank or any Lender may otherwise have to bring any
action or proceeding relating to this Guaranty against the Guarantor or its properties in the
courts of any jurisdiction.

          (c) The Guarantor 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 Guaranty in any court
referred to in 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.

Exhibit D - 4

 

          (d) The Guarantor irrevocably consents to service of process by delivery of notice
to the address set forth below. Nothing in this Guaranty will affect the right of any Person to
serve process in any other manner permitted by law.

EXTENT PERMITTED BY APPLICABLE LAW, ANY RIGHT IT MAY HAVE TO A TRIAL BY JURY IN ANY LEGAL
PROCEEDING DIRECTLY OR INDIRECTLY ARISING OUT OF OR RELATING TO THIS GUARANTY OR THE TRANSACTIONS
CONTEMPLATED HEREBY (WHETHER BASED ON CONTRACT, TORT OR ANY OTHER THEORY). EACH PARTY HERETO (A)

OR OTHERWISE, THAT SUCH OTHER PARTY WOULD NOT, IN THE EVENT OF LITIGATION, SEEK TO ENFORCE THE
FOREGOING WAIVER AND (B) ACKNOWLEDGES THAT IT AND THE OTHER PARTIES HERETO HAVE BEEN INDUCED TO
ENTER INTO THIS AGREEMENT BY, AMONG OTHER THINGS, THE MUTUAL WAIVERS AND CERTIFICATIONS IN THIS
SECTION.

     Section 19. Integration; Effectiveness. This Guaranty alone sets forth the entire
understanding of the Guarantor and the Beneficiaries relating to the guarantee by the Guarantor of
the Liabilities and constitutes the entire contract between the parties relating to the subject
matter hereof and supersedes any and all previous agreements and understandings, oral or written,

not amend, limit or impair any other Loan Document. This Guaranty shall become effective when it

not render such Guarantor’s liabilities and obligations hereunder subject to avoidance under
