          This CREDIT AGREEMENT (this “Agreement”), dated as of September 9, 2011, among
CENTERPOINT ENERGY HOUSTON ELECTRIC, LLC, a Texas limited liability company (the
“Borrower”), the banks and other financial institutions from time to time parties hereto
(individually, a “Bank” and, collectively, the “Banks”), BANK OF AMERICA, N.A. and

     “Agreement” has the meaning specified in the introduction to this Agreement.

     “Alternate Base Rate” means, for any day, a rate per annum (rounded upwards, if
necessary, to the next 1/100 of 1%) equal to the greatest of (a) the Prime Rate in effect on
such day, (b) the Federal Funds Effective Rate in effect on such day plus 1/2 of 1% and (c)
the Eurodollar Rate for a one-month Interest Period for such day (or if such day is not a
Business Day, the immediately preceding Business Day) plus 1%; provided that, for
purposes of this definition, the Eurodollar Rate for any day shall be based on the rate
appearing on Page LIBOR01 of the Reuters screen (or on any successor or substitute page of
such service, or any successor or substitute for such service, providing rate quotations
comparable to those currently provided on such page of such service, as determined by the
Administrative Agent from time to time for purposes of providing
quotations of interest rates applicable to dollar deposits in the London interbank
market) at approximately 11:00 A.M., London time, on such day. Any change in the Alternate

 

 

Base Rate due to a change in the Prime Rate, the Federal Funds Effective Rate or the
Eurodollar Rate shall be effective as of the opening of business on the effective date of
such change in the Prime Rate, the Federal Funds Effective Rate or the Eurodollar Rate,
respectively.

     “Applicable Rate” means, for any day, with respect to any Eurodollar Rate Loan
or ABR Loan, or with respect to the Commitment Fees payable hereunder, as they case may be,
the applicable rate per annum set forth below under the caption “Eurodollar Rate Margin”,
“ABR Margin” or “Commitment Fee Rate”, as the case may be, based upon the Designated Ratings
by S&P, Moody’s and Fitch, respectively, applicable on such day:

	 	 	 	 	 	 	 	 	 	 	 	 	 
	Designated	 	Eurodollar Rate	 	 	 	 
	Rating	 	Margin	 	ABR Margin	 	Commitment Fee Rate
	Higher than
BBB+/Baa1/BBB+
	 	 	1.125	%	 	 	0.125	%	 	 	0.125	%
	BBB+/Baa1/BBB+
	 	 	1.25	%	 	 	0.25	%	 	 	0.175	%

	 	 	2.25	%	 	 	1.25	%	 	 	0.50	%

     For purposes of the foregoing, (a) if the Designated Ratings are split and all
three Designated Ratings fall in different levels, the Applicable Rate shall be based upon
the middle Designated Rating; (b) if the Designated Ratings are split and two of the
Designated Ratings fall in the same level (the “Majority Level”) and the third
Designated Rating is in a different level, the Applicable Rate shall be based upon the
Majority Level; (c) if only two of the Rating Agencies issue a Designated Rating, the
Applicable Rate shall be based upon the higher of such Designated Ratings, provided
that if the higher Designated Rating is two or more levels above the lower Designated
Rating, the Applicable Rate shall be based upon the rating next below the higher of the two
Designated Ratings; (d) if only one of the three Rating Agencies issues a Designated Rating,
the Applicable Rate shall be based upon such Designated Rating; and (e) if the Designated
Ratings established by any of the three Rating Agencies shall be changed (other than as a
result of a change in the rating system of such Rating Agency), such change shall be
effective as of the date on which it is first announced by the applicable Rating Agency (it
being understood that a change in outlook status (e.g., watch status, negative outlook
status) does not constitute a change in any Designated Rating for purposes hereof). If the
rating system of any Rating Agency shall change, or if any Rating Agency shall cease to be
in the business of rating corporate debt obligations, the Borrower and the Administrative
Agent shall negotiate in good faith if necessary to amend this definition and the
definitions of “Designated Rating” and “Rating Agencies”
to reflect such changed rating system or the unavailability of Designated Ratings from
such Rating Agency and, pending the effectiveness of any such amendment, the

2

 

Applicable Rate shall be determined by reference to the Designated Rating of such Rating Agency most

ARTICLE II

AMOUNTS AND TERMS OF THE LOANS AND LETTERS OF CREDIT

     SECTION 2.1. The Commitments

     (a) Each Bank severally agrees, on the terms and subject to the conditions hereinafter set
forth, to make revolving credit loans (each such loan, a “Revolving Loan”) to the Borrower
from time to time on any Business Day during the period from the Closing Date until the Termination
Date in an aggregate principal amount that will not result in (i) such Bank’s Outstanding
Extensions of Credit exceeding such Bank’s Commitment or (ii) the Total Outstanding Extensions of
Credit exceeding the Total Commitments; provided that no Revolving Loan shall be made as a
Eurodollar Rate Loan with an Interest Period ending after the Termination Date.

     (b) Each Revolving Borrowing shall consist of Revolving Loans of the same Type made on the
same day by the Banks ratably according to their respective Revolving Percentages. Each Revolving
Borrowing of Eurodollar Rate Loans by the Borrower shall be in an aggregate principal amount of
$5,000,000 or an integral multiple of $1,000,000 in excess thereof; provided that no more
than ten Eurodollar tranches shall be outstanding at any time. Each Revolving Borrowing of ABR
Loans by the Borrower shall be in an aggregate principal amount of $1,000,000 or an integral
multiple of $500,000 in excess thereof. Within the limits of the applicable Commitments, the
Borrower may borrow, prepay pursuant to Section 4.6 and reborrow Revolving Loans under this Section
2.1. The principal amount outstanding on the Revolving Loans and all other amounts accrued
hereunder shall be due and payable on the Termination Date, together with accrued and unpaid
interest thereon.

     SECTION 2.2. Procedure for Revolving Loan Borrowing

     (a) The Borrower may borrow Revolving Loans on any Business Day during the period from and
including the Closing Date to and excluding the Termination Date, provided that the
Borrower shall give the Administrative Agent irrevocable oral notice or written notice pursuant to
a notice of borrowing, in substantially the form of Exhibit A hereto (“Notice of
Borrowing”), which shall be signed by the Borrower and shall specify therein the requested (i)
date of such Borrowing, (ii) Type of Revolving Loans comprising such Borrowing, (iii) aggregate
amount of such Borrowing and (iv) Interest Period for the Revolving Loans comprising such Borrowing
(in the case of any Borrowing of Eurodollar Rate Loans):

     (i) not later than 11:00 A.M. (New York City time) on the third Business Day prior to
the date of the proposed Borrowing in the case of a Borrowing of Eurodollar Rate Loans;

     (ii) not later than 11:00 A.M. (New York City time) on the Business Day immediately
preceding the date of the proposed Borrowing in the case of a Borrowing of Early Funding ABR
Loans; and

25

 

     (iii) not later than 11:00 A.M. (New York City time) on the same Business Day of the
proposed Borrowing in the case of a Borrowing of any other ABR Loans.

With respect to any oral notice of borrowing given by the Borrower, the Borrower shall promptly
thereafter confirm such notice in writing pursuant to a Notice of Borrowing. Upon receipt of any
such notice, the Administrative Agent shall promptly notify each Bank thereof. Each Bank shall,
before 1:00 P.M. (New York City time) on the requested Borrowing Date, make available to the
Administrative Agent at the Funding Office, in immediately available funds, such Bank’s applicable
Revolving Percentage of such Borrowing; provided, however, that, in the event of a
requested ABR Loan with respect to which the Borrower has delivered its Notice of Borrowing on the
Business Day immediately preceding the requested Borrowing Date (an “Early Funding ABR
Loan”), each Bank shall make its applicable Revolving Percentage of such Borrowing available
before 10:00 A.M. (New York City time) on the requested Borrowing Date. The Administrative Agent
shall, no later than 2:00 P.M. (New York City time) on such date (or no later than 11:00 A.M. (New
York City time), in the case of an Early Funding ABR Loan), make available to the Borrower the
proceeds of the Revolving Loans received by the Administrative Agent hereunder by crediting such
account of the Borrower which the Administrative Agent and the Borrower shall from time to time
designate. Each Notice of Borrowing shall be irrevocable and binding on the Borrower.

     (b) Unless the Administrative Agent shall have received notice from a Bank at least two hours
prior to the applicable time described in clause (a) above by which such Bank is required to
deliver its funds to the Administrative Agent with respect to any Borrowing that such Bank will not
make available to the Administrative Agent such Bank’s applicable Revolving Percentage of such
Borrowing, the Administrative Agent may assume that such Bank has made such portion available to
the Administrative Agent on the date of such Borrowing in accordance with Section 2.2(a) and the
Administrative Agent may, in reliance upon such assumption, make available to the Borrower on such
date a corresponding amount. If such amount is made available to the Administrative Agent on a
date after such date of Borrowing, such Bank shall pay to the Administrative Agent on demand an
amount equal to the product of (i) the daily average Federal Funds Effective Rate during such
period, times (ii) the amount of such Bank’s applicable Revolving Percentage of such Borrowing,
times (iii) a fraction, the numerator of which is the number of days that elapse from and including
such date of Borrowing to the date on which such Bank’s applicable Revolving Percentage of such
Borrowing shall have become immediately available to the Administrative Agent and the denominator
of which is 360. A certificate of the Administrative Agent submitted to any Bank with respect to
any amounts owing under this Section 2.2(b) shall be conclusive in the absence of manifest error.
If such Bank shall repay to the Administrative Agent such corresponding amount, such amount so
repaid shall constitute such Bank’s Revolving Loan as part of such Borrowing for purposes of this
Agreement. If such Bank’s applicable Revolving Percentage of such Borrowing is not in fact made
available to the Administrative Agent by such Bank within one (1) Business Day of such date of
Borrowing, the Administrative Agent shall be entitled to recover such amount with interest thereon
at the rate per annum, equal to (i) the Alternate Base Rate (in the case of ABR
Loans) or (ii) the Federal Funds Effective Rate (in the case of Eurodollar Rate Loans), on
demand, from the Borrower.

26

 

     (c) The failure of any Bank to make the Loan to be made by it as part of any Borrowing shall
not relieve any other Bank of its obligation, if any, hereunder to make its Loan on the date of
such Borrowing, but no Bank shall be responsible for the failure of any other Bank to make the Loan
to be made by such other Bank on the date of any Borrowing.

     SECTION 2.3. [Reserved]

     SECTION 2.4. Swingline Loans

     (a) Subject to the terms and conditions set forth herein (including satisfaction of the
conditions precedent set forth in Sections 5.1 (on the Closing Date) and 5.2 (upon the making of
each Swingline Loan)), the Swingline Lender agrees to make Swingline Loans to the Borrower from
time to time during the period from the Closing Date until the Termination Date, in an aggregate
principal amount at any time outstanding that will not result in (i) the aggregate principal amount
of outstanding Swingline Loans exceeding $50,000,000 (the “Swingline Commitment”) or (ii)
the Total Outstanding Extensions of Credit exceeding the Total Commitments; provided that
the Swingline Lender shall not be required to make a Swingline Loan to refinance an outstanding
Swingline Loan. Each Swingline Loan shall be in an amount equal to $500,000 or a whole multiple of
$100,000 in excess thereof. The Swingline Loans may from time to time be (i) ABR Loans, (ii) Money
Market Rate Loans or (iii) a combination thereof, as determined by the Borrower and notified to the
Administrative Agent and the Swingline Lender in accordance herewith (and shall not be entitled to
be converted into Eurodollar Rate Loans). Within the foregoing limits and subject to the terms and
conditions set forth herein, the Borrower may borrow, prepay and reborrow Swingline Loans. The
Borrower hereby unconditionally promises to pay to the Swingline Lender the then unpaid principal
amount of each Swingline Loan on the earlier of the Maturity Date and the fourteenth (14th)
Business Day after such Swingline Loan is made.

     (b) To request a Swingline Loan, the Borrower shall notify the Administrative Agent and the
Swingline Lender of such request by telephone (confirmed pursuant to a Notice of Borrowing by
facsimile or e-mail), not later than (i) 12:00 Noon (New York City time) in the case of ABR Loans,
or (ii) 2:00 P.M. (New York City time) in the case of Money Market Rate Loans, on the day of a
proposed Swingline Loan. Each such notice shall be irrevocable and shall specify the requested
date (which shall be a Business Day), amount of the requested Swingline Loan, and whether the
requested Swingline Loan shall be an ABR Loan, a Money Market Rate Loan or a combination thereof.
The Swingline Lender shall make each Swingline Loan available to the Borrower by means of a credit
to the general deposit account of the Borrower with the Swingline Lender (or, in the case of a
Swingline Loan made to finance the reimbursement of any payment that an Issuing Bank makes under a
Letter of Credit as provided in Section 2.5(e), by remittance to the Issuing Bank) by 3:00 P.M.
(New York City time) on the requested date of such Swingline Loan.

     (c) The Swingline Lender may, by written notice given to the Administrative Agent not later
than 10:00 A.M. (New York City time) on any Business Day, require the Banks to
acquire participations on such Business Day in all or a portion of the Swingline Loans
outstanding. Such notice shall specify the aggregate amount of Swingline Loans in which Banks will
participate. Promptly upon receipt of such notice, the Administrative Agent will give notice

27

 

thereof to each Bank, specifying in such notice such Bank’s Revolving Percentage of such Swingline
Loan or Swingline Loans. Each Bank hereby absolutely and unconditionally agrees, upon receipt of
notice as provided above, to pay to the Administrative Agent, for the account of the Swingline
Lender, such Bank’s Revolving Percentage of such Swingline Loan or Swingline Loans. Each Bank
acknowledges and agrees that its obligation to acquire participations in Swingline Loans pursuant
to this paragraph is absolute and unconditional and shall not be affected by any circumstance
whatsoever, including 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. Each Bank shall comply with its obligation under this
paragraph by wire transfer of immediately available funds, in the same manner as provided in
Section 2.2 with respect to Revolving Loans made by such Bank (and Section 2.2 shall apply,
mutatis mutandis, to the payment obligations of the Bank), and the Administrative
Agent shall promptly pay to the Swingline Lender the amounts so received by it from the Banks. The
Administrative Agent shall notify the Borrower of any participations in any Swingline Loan acquired
pursuant to this paragraph, and thereafter payments in respect of such Swingline Loan shall be made
to the Administrative Agent and not to the Swingline Lender. Any amounts received by the Swingline
Lender from the Borrower (or other party on behalf of the Borrower) in respect of a Swingline Loan
after receipt by the Swingline Lender of the proceeds of a sale of participations therein shall be
promptly remitted to the Administrative Agent; any such amounts received by the Administrative
Agent shall be promptly remitted by the Administrative Agent to the Banks that shall have made
their payments pursuant to this paragraph and to the Swingline Lender, as their interests may
appear; provided that any such payment so remitted shall be repaid to the Swingline Lender
or to the Administrative Agent, as applicable, if and to the extent such payment is required to be
refunded to the Borrower for any reason. The purchase of participations in a Swingline Loan
pursuant to this paragraph shall not relieve the Borrower of any default in the payment thereof.

     SECTION 2.5. Letters of Credit. (a) L/C Commitment.

     (i) Prior to the Closing Date, the Existing Issuing Bank has issued the Existing
Letters of Credit which, from and after the Closing Date, shall constitute Letters of Credit
hereunder.

     (ii) Subject to the terms and conditions hereof (including satisfaction of the
conditions precedent set forth in Sections 5.1 (on the Closing Date) and 5.2 (upon the
issuance of each Letter of Credit)), each Issuing Bank, in reliance on the agreements of the
other Banks set forth in Section 2.5(d), agrees to issue standby letters of credit (together
with the Existing Letters of Credit, the “Letters of Credit”) for the account of the
Borrower in support of obligations (including performance, bid and similar bonding
obligations and credit enhancement) of the Borrower and its Affiliates on any Business Day
on or after the Closing Date and prior to the Termination Date in such form as may be
approved from time to time by such Issuing Bank; provided that no Issuing Bank shall
issue any Letter of Credit if, after giving effect to such issuance, (A) the L/C
Obligations would exceed the L/C Commitment or (B) the Total Outstanding Extensions of
Credit then outstanding would exceed the Total Commitments then in effect and
provided, further, that (i) JPMorgan Chase Bank, N.A. shall not be required,
without its consent, to issue Letters of Credit in excess of $60,000,000 at any time
outstanding and (ii) The

28

 

Royal Bank of Scotland plc shall not be required, without its
consent, to issue Letters of Credit in excess of $15,000,000 at any time outstanding.

     (iii) Each Letter of Credit shall be denominated in Dollars and shall be a standby
letter of credit issued to support obligations of the Borrower or any of its Affiliates,
contingent or otherwise, and expire no later than the Maturity Date.

     (iv) No Issuing Bank shall at any time be obligated to issue any Letter of Credit
hereunder if such issuance would conflict with, or cause such Issuing Bank or any L/C
Participant to exceed any limits imposed on such Issuing Bank by, any applicable Requirement
of Law.

     (b) Procedure for Issuance of Letters of Credit. The Borrower may from time to time
request that an Issuing Bank (i) issue a Letter of Credit by delivering to such Issuing Bank at its
address for notices specified herein an Application therefor, completed to the satisfaction of such
Issuing Bank or (ii) extend, modify or increase the amount of an existing Letter of Credit by
delivering to such Issuing Bank at its address for notices specified herein a notice identifying
the Letter of Credit to be extended, modified or increased, the proposed date of such extension,
modification or increase, the name and address of the beneficiary thereof and such other
information as shall be necessary to extend, modify or increase such Letter of Credit. Upon
receipt of any Application or a request for an extension, modification or increase of an existing
Letter of Credit, the Issuing Bank will process such Application or request and shall promptly
issue the Letter of Credit (or an amendment to such existing Letter of Credit, as applicable)
requested thereby (but in no event shall any Issuing Bank be required to issue any Letter of Credit
(or extension, modification or increase of an existing Letter of Credit) earlier than two Business
Days after its receipt of the Application or request therefor, as applicable) by issuing the
original of such Letter of Credit (or amendment thereof, as applicable) in a form satisfactory to
the Borrower to the beneficiary thereof or as otherwise may be agreed by such Issuing Bank and
Borrower. The relevant Issuing Bank shall furnish a copy of such Letter of Credit (or amendment
thereof, as applicable) to the Borrower promptly following the issuance thereof and notify the
Banks of the amount thereof. In the event of any inconsistency between the terms and conditions of
this Agreement and the terms and conditions of the Application or other agreement submitted by the
Borrower to, or entered into by the Borrower with, the Issuing Bank relating to any Letter of
Credit, the terms and conditions of this Agreement shall control.

     (c) Fees, Commissions and Other Charges.

     (i) The Borrower shall pay to the Administrative Agent, for the account of the L/C
Participants in accordance with their respective Revolving Percentages, a Letter of Credit
participation fee with respect to their participations in each Letter of Credit, which shall
accrue at the rate per annum equal to the Applicable Rate for Eurodollar Rate Loans then in
effect, calculated on the basis of a 365- (or 366-, as the case may be) day year, on
the aggregate amount available to be drawn under such Letter of Credit for each day
during the period from the last L/C Fee Payment Date (or, if later, the date of issuance of
such Letter of Credit) to the date on which such payment is due hereunder. The Borrower
shall pay to the Administrative Agent, for the account of the relevant Issuing Bank, a
fronting fee with respect to each Letter of Credit issued by such Issuing Bank,

29

 

which shall accrue at the rate per annum equal to 0.20%, calculated on the basis of a 365- (or 366-, as
the case may be) day year, on the aggregate amount available to be drawn under such Letter
of Credit issued by such Issuing Bank for each day during the period from the last L/C Fee
Payment Date to the date upon which such payment is due hereunder. Such Letter of Credit
participation fees and fronting fees shall be payable in arrears on each L/C Fee Payment
Date and shall be nonrefundable.

     (ii) In addition to the foregoing fees, the Borrower shall pay or reimburse each
Issuing Bank for such normal and customary costs and reasonable expenses as are incurred or
charged by such Issuing Bank in issuing, effecting payment under, amending or otherwise
administering any Letter of Credit.

     (iii) The Administrative Agent shall, promptly following its receipt thereof,
distribute to the relevant Issuing Bank and the L/C Participants all fees received by the
Administrative Agent for their respective accounts pursuant to this Section 2.5(c).

     (d) L/C Participations.

     (i) Each Issuing Bank irrevocably agrees to grant and hereby grants to each L/C
Participant, and, to induce each Issuing Bank to issue Letters of Credit hereunder, each L/C
Participant irrevocably agrees to accept and purchase and hereby accepts and purchases from
such Issuing Bank, on the terms and conditions hereinafter stated, for such L/C
Participant’s own account and risk an undivided interest equal to such L/C Participant’s
Revolving Percentage in each Issuing Bank’s obligations and rights under each Letter of
Credit issued hereunder and the aggregate amount of drawings under Letters of Credit that
have not then been reimbursed pursuant to Section 2.5(e). Each L/C Participant
unconditionally and irrevocably agrees with each Issuing Bank that, if a draft is paid under
any Letter of Credit for which such Issuing Bank is not reimbursed in full by the Borrower
in accordance with the terms of this Agreement, such L/C Participant shall pay to such
Issuing Bank upon demand at such Issuing Bank’s address for notices specified herein an
amount equal to such L/C Participant’s Revolving Percentage of the amount of such draft, or
any part thereof, which is not so reimbursed. Each Bank acknowledges and agrees that its
obligation to acquire participations pursuant to this Section 2.5(d)(i) 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.

     (ii) If any amount required to be paid by any L/C Participant to an Issuing Bank
pursuant to Section 2.5(d)(i) in respect of any unreimbursed portion of any payment made by
such Issuing Bank under any Letter of Credit is not paid to such Issuing Bank
within one Business Day after the date such payment is due, such L/C Participant shall
pay to such Issuing Bank on demand an amount equal to the product of (A) such amount, times
(B) the daily average Federal Funds Effective Rate as quoted by the relevant Issuing Bank,
during the period from and including the date such payment is required to the date on which
such payment is immediately available to such Issuing Bank, times

30

 

(C) a fraction, the numerator of which is the number of days that elapse during such period and the denominator
of which is 360. If any such amount required to be paid by any L/C Participant pursuant to
Section 2.5(d)(i) is not in fact made available to the relevant Issuing Bank by such L/C
Participant within three (3) Business Days after the date such payment is due, such Issuing
Bank shall be entitled to recover from such L/C Participant, on demand, such amount with
interest thereon calculated from such due date at the Alternate Base Rate. A certificate of
the relevant Issuing Bank submitted to any L/C Participant with respect to any amounts owing
under this subsection shall be conclusive in the absence of manifest error.

     (iii) Whenever, at any time after any Issuing Bank has made payment under any Letter of
Credit and has received from any L/C Participant its pro rata share of such payment in
accordance with Section 2.5(d)(i), such Issuing Bank receives any payment related to such
Letter of Credit (whether directly from the Borrower or otherwise, including proceeds of
collateral applied thereto by the Issuing Bank), or any payment of interest on account
thereof, such Issuing Bank will distribute to such L/C Participant its pro rata share
thereof; provided, however, that in the event that any such payment received
by such Issuing Bank shall be required to be returned by such Issuing Bank, such L/C
Participant shall return to such Issuing Bank the portion thereof previously distributed by
such Issuing Bank to it.

     (e) Reimbursement Obligation of the Borrower. (i) The Borrower shall reimburse each
Issuing Bank for any payment that such Issuing Bank makes under a Letter of Credit on or before the
date of such payment if the Borrower receives notice of such payment at or before 10:00 A.M. (New
York City time) on the date such payment is made by such Issuing Bank; provided,
however, that, if the Borrower does not receive notice of such payment at or before such
time on such date or does not reimburse such Issuing Bank under this Section 2.5(e)(i), then
Section 2.5(e)(ii) shall apply. Each such payment shall be made to the relevant Issuing Bank at
its address for notices specified herein in Dollars and in immediately available funds.

     (ii) Notwithstanding Section 5.2, each drawing under any Letter of Credit shall be
deemed to constitute a Borrowing of ABR Loans in the amount of such drawing unless the
Borrower has reimbursed the relevant Issuing Bank under Section 2.5(e)(i). The Borrowing
Date with respect to each such borrowing shall be deemed to be the date of such drawing.

     (f) Obligations Absolute.

     (i) The Borrower’s payment obligations under Section 2.5(e) shall be absolute,
irrevocable and unconditional under any and all circumstances and irrespective of any
set-off, counterclaim or defense to payment that the Borrower may have or have had against
the relevant Issuing Bank or any beneficiary of a Letter of Credit, other than a
defense based upon the gross negligence or willful misconduct as determined by a final,
non-appealable judgment of a court of competent jurisdiction.

     (ii) The Borrower also agrees with each Issuing Bank that no Issuing Bank shall be
responsible for, and the Borrower’s Reimbursement Obligations under

31

 

Section 2.5(e) shall not be affected by, among other things, (i) the validity or genuineness of documents or of any
endorsements thereon, even though such documents shall in fact prove to be invalid,
fraudulent or forged, (ii) any dispute between or among the Borrower and any beneficiary of
any Letter of Credit or any other party to which such Letter of Credit may be transferred,
(iii) any claims whatsoever of the Borrower against any beneficiary of such Letter of Credit
or any such transferee, (iv) any lack of validity or enforceability of any Letter of Credit
or this Agreement, or any term or provision therein or herein, (v) payment by the Issuing
Bank under a Letter of Credit against presentation of a draft or other document that does
not comply with the terms of such Letter of Credit or (vi) 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 or under any Letter of Credit.

     (iii) No Issuing Bank shall be liable for any error, omission, interruption or delay in
transmission, dispatch or delivery of any message or advice, however transmitted, in
connection with any Letter of Credit, except for errors or omissions caused by such Issuing
Bank’s gross negligence or willful misconduct as determined by a final, non-appealable
judgment of a court of competent jurisdiction.

     (iv) The Borrower agrees that any action taken or omitted by any Issuing Bank under or
in connection with any Letter of Credit or the related drafts or documents, if done in the
absence of gross negligence or willful misconduct as determined by a final, non-appealable
judgment of a court of competent jurisdiction, shall be binding on the Borrower and shall
not result in any liability of such Issuing Bank to the Borrower.

     (g) Letter of Credit Payments. If any draft shall be presented for payment under any
Letter of Credit, the relevant Issuing Bank shall promptly notify the Borrower by telephone
(confirmed in writing) of the date and amount thereof and whether such Issuing Bank has made or
will make a payment thereunder. The responsibility of such Issuing Bank to the Borrower in
connection with any draft presented for payment under any Letter of Credit shall, in addition to
any payment obligation expressly provided for in such Letter of Credit, be limited to determining
that the documents (including each draft) delivered under such Letter of Credit in connection with
such presentment are in conformity with such Letter of Credit.

     (h) Application. To the extent that any provision of any Application related to any
Letter of Credit is inconsistent with the provisions of this Section 2.5, the provisions of this
Section 2.5 shall control.

     (i) Replacement, Termination or Resignation of an Issuing Bank.

     (i) Any Issuing Bank may be replaced at any time by written agreement among the
Borrower, the replaced Issuing Bank and the successor Issuing Bank. The Administrative
Agent shall notify the Banks of any such replacement of such Issuing

32

 

Bank. At the time any such replacement shall become effective, the Borrower shall pay all unpaid fees accrued for
the account of such replaced Issuing Bank pursuant to Section 2.5(c). From and after the
effective date of any such replacement, (A) the applicable successor Issuing Bank shall have
all the rights and obligations of an Issuing Bank under this Agreement with respect to
Letters of Credit to be issued thereafter and (B) 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.

     (ii) Any Issuing Bank may be terminated at any time upon not less than 10 Business
Days’ written notice by the Borrower to the Administrative Agent and such Issuing Bank. The
Administrative Agent shall notify the Banks of any such termination of an Issuing Bank. At
the time any such termination shall become effective, the Borrower shall pay all unpaid fees
accrued for the account of the terminated Issuing Bank pursuant to Section 2.5(c). After
the effective date of the termination of an Issuing Bank hereunder, (i) such 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 termination, but shall not be required to issue additional Letters of Credit and (ii)
if no Letter of Credit previously issued by such Issuing Bank is then outstanding and no LC
Exposure in respect of any such Letter of Credit then exists, such terminated Issuing Bank
shall not be deemed an Issuing Bank for purposes of any provisions hereof or the other Loan
Documents which require the consent or approval of each Issuing Bank (provided that such
terminated Issuing Bank’s consent shall be required for any waiver, amendment or
modification of this Agreement or any other Loan Document that affects the rights or duties
of such terminated Issuing Bank hereunder).

     (iii) Any Issuing Bank may resign as an Issuing Bank at any time after which such
Issuing Bank is no longer a Bank upon not less than 15 Business Days’ prior written notice
to the Administrative Agent and the Borrower. The Administrative Agent shall notify the
Banks of any such resignation of such Issuing Bank. At the time any such resignation shall
become effective, the Borrower shall pay all unpaid fees accrued for the account of such
resigned Issuing Bank pursuant to Section 2.5(c). From and after the effective date of any
such resignation, references herein to the term “Issuing Bank” shall be deemed to refer to
such resigned Issuing Bank if the context shall so require. After the resignation of an
Issuing Bank hereunder, the resigned 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 resignation, but shall not be
required to issue additional Letters of Credit.

     SECTION 2.6. Increase in the Total Commitments. (a) The Borrower may, without the
consent of the Banks, the Administrative Agent or the Issuing Banks, from time to time cause an
increase in the Total Commitments (each, a “Commitment Increase”), whether or not the Total

33

 

Commitments have been reduced pursuant to Section 4.5, by obtaining Commitments from one or more
additional Eligible Assignees that are not already Banks hereunder (each, a “New Bank”)
and/or by allowing one or more existing Banks to increase their respective Commitments (each, an
“Increasing Bank”); provided that (i) each Commitment Increase shall be in a
minimum amount of $10,000,000 or an integral multiple of $5,000,000 in excess thereof, (ii) each
Commitment Increase shall become effective as of a date (the “Increase Date”) that is at
least 90 days prior to the Maturity Date then in effect, (iii) no such Commitment Increase shall
result in the Total Commitments exceeding $450,000,000, (iv) each New Bank and each Increasing Bank
providing any portion of any Commitment Increase must be satisfactory to the Administrative Agent
and each Issuing Bank, which approval shall not be unreasonably withheld, delayed or conditioned,
(v) no Bank shall be required to provide any such increase, and (vi) on the date of any request by
the Borrower for a Commitment Increase and on the related Increase Date, the applicable conditions
set forth in Section 5.3 shall be satisfied.

     (b) Each Commitment Increase must be requested by written notice from the Borrower to the
Administrative Agent substantially in the form attached hereto as Exhibit E. Each such
notice shall specify (i) the proposed Increase Date, (ii) the amount of the requested Commitment
Increase (which amount shall conform to the requirements of Section 2.6(a)), (iii) the identity of
each New Bank and/or each Increasing Bank that is participating in such Commitment Increase, and
(iv) the amount of the respective Commitments of the then existing Banks and the New Banks from and
after the applicable Increase Date. If the Administrative Agent and each Issuing Bank approve the
New Banks and/or Increasing Banks participating in such Commitment Increase (such approval not to
be unreasonably withheld, delayed or conditioned), the Borrower, the Administrative Agent, the
Issuing Banks and the applicable New Banks and/or Increasing Banks shall execute a Commitment
Increase Agreement, and such Commitment Increase shall be effective on the Increase Date specified
therein; provided that, as a condition to the effectiveness of any Commitment Increase, if
requested by the Administrative Agent, the Borrower shall deliver to the Administrative Agent (A)
certified copies of resolutions of the Board of Directors of the Borrower or the Executive
Committee of such Board approving such Commitment Increase and (B) opinions of counsel for the
Borrower (which may be in-house counsel), in form and substance reasonably acceptable to the
Administrative Agent, covering such matters covered by the opinions of counsel delivered pursuant
to Section 5.1(c) as the Administrative Agent may reasonably request. On each Increase Date, upon
fulfillment of the conditions set forth in the immediately preceding sentence, the Administrative
Agent shall notify the Banks (including each New Bank) and the Borrower of the occurrence of the
Commitment Increase effected on such Increase Date and shall record in the Register the relevant
information with respect to each Increasing Bank and each New Bank.

     (c) The Borrower acknowledges that, if the Total Commitments are increased on a non-pro-rata
basis pursuant to any Commitment Increase and there are any outstanding Loans as of the Increase
Date for such Commitment Increase, prepayments and/or fundings of all or portions of certain Loans
on such date may be required in order for each Bank to hold its
Revolving Percentage of each outstanding Loan after giving effect to such Commitment Increase
(and any such prepayment or funding shall be subject to the other provisions of this Agreement).
Effective upon each Commitment Increase, the amount of the participations held by each Bank in each
Letter of Credit then outstanding shall be adjusted such that, after giving effect to such

34

 

adjustments, each Bank shall hold participations in each such Letter of Credit in accordance with
the Revolving Percentage of such Bank after giving effect to such Commitment Increase.

     SECTION 2.7. Extension Option. The Borrower may request that the Commitments be extended for up to
two additional one year periods by providing not less than 30 days’ written notice (the date of
such notice, a “Notice Date”) to the Administrative Agent prior to any anniversary of the
Closing Date. If a Bank agrees, in its individual and sole discretion, to extend its Commitment
(such Bank, an “Extending Bank”), it will notify the Administrative Agent, in writing, of
its decision to do so no later than 20 days after the applicable Notice Date. The Administrative
Agent will notify the Borrower, in writing, of the Banks’ decisions no later than 25 days after
such Notice Date. The Extending Banks’ Commitments will be extended for an additional year from
the then current Maturity Date so long as (i) the Commitments of the Extending Banks (after giving
effect to any assumption by any Extending Banks of Commitments of Declining Banks as described
below), together with the Commitments of any new Banks that replace any Declining Banks, represent
more than 50% of the Total Commitments then in effect, and (ii) on the date of any request by the
Borrower to extend the Commitments, the applicable conditions set forth in Section 5.3 shall be
satisfied. No Bank shall be required to consent to any such extension request and any Bank that
declines or does not respond to the Borrower’s request for an extension of the Commitments (a
“Declining Bank”) will have its Commitment terminated on the then existing Maturity Date
(without regard to any extension of the Commitments of other Banks). The Borrower will have the
right to accept Commitments from any Eligible Assignee that is not a Bank in an aggregate amount up
to the aggregate amount of the Commitments of any Declining Banks; provided that (i) the
Extending Banks will have the right to increase their Commitments in an aggregate amount up to the
aggregate amount of the Declining Banks’ Commitments before the Borrower will be permitted to
substitute any Eligible Assignees for the Declining Banks and (ii) any Eligible Assignee proposed
to be substituted for a Declining Bank (unless such Eligible Assignee is an affiliate of a Bank)
must be approved by the Administrative Agent and the Issuing Banks, such approval, in each case,
not to be unreasonably withheld, delayed or conditioned. The Borrower may only extend the Maturity
Date twice during the term of this Agreement pursuant to this Section 2.7.

     SECTION 2.8. Defaulting Banks. Notwithstanding any provision of this Agreement or any
other Loan Document to the contrary, if any Bank becomes a Defaulting Bank, then the following
provisions shall apply for so long as such Bank is a Defaulting Bank:

     (a) Commitment Fees shall cease to accrue on the unfunded portion of the Commitment of such
Defaulting Bank pursuant to Section 3.2(a);

     (b) the Commitment and Outstanding Extensions of Credit of such Defaulting Bank shall not be
included in determining whether all Banks (or each Bank) or the Majority Banks have taken or may
take any action hereunder (including any consent to any amendment, waiver or other modification
pursuant to Section 10.1); provided, that this clause (b) shall not apply to the vote of a
Defaulting Bank in the case of an amendment, waiver or other modification
requiring the consent of such Bank or each Bank affected thereby if such Bank is an affected
Bank; provided, further, that there shall not be any amendment, modification or
waiver (i) of any provision of Section 4.2 or Section 10.1 in a manner that would alter the pro
rata sharing of payments required thereby, or (ii) causing the reduction of the percentage
specified in the

35

 

definition of Majority Banks, or (iii) causing the consent to the assignment or
transfer by the Borrower of any of its respective rights and obligations under this Agreement and
the other Loan Documents, in each case without the consent of such Bank;

     (c) if any Swingline Exposure or L/C Obligations exist at the time such Bank becomes a
Defaulting Bank then;

     (i) all or any part of the Swingline Exposure and L/C Exposure of such
Defaulting Bank shall be reallocated (effective as of the date such Bank becomes a
Defaulting Bank) among the non-Defaulting Banks in accordance with their respective
Revolving Percentages, but only to the extent the sum of all non-Defaulting Banks’
Outstanding Extensions of Credit plus such Defaulting Bank’s Swingline Exposure and
L/C Exposure does not exceed the total of all non-Defaulting Banks’ Commitments;

     (ii) if the reallocation described in clause (i) above cannot, or can only
partially, be effected, the Borrower shall, within two Business Days following the
Borrower’s receipt of written notice by the Administrative Agent, (x) first,
prepay such Defaulting Bank’s Swingline Exposure and (y) second, cash
collateralize for the benefit of the applicable Issuing Banks only the Borrower’s
obligations corresponding to such Defaulting Bank’s L/C Exposure (after giving
effect to any partial reallocation pursuant to clause (i) above) in accordance with
the procedures set forth in Section 8.2 for so long as such L/C Exposure is
outstanding;

     (iii) if the Borrower cash collateralizes any portion of such Defaulting Bank’s
L/C Exposure pursuant to clause (ii) above, the Borrower shall not be required to
pay any fees to such Defaulting Bank pursuant to Section 2.5(c) with respect to such
Defaulting Bank’s L/C Exposure during the period such Defaulting Bank’s L/C Exposure
is cash collateralized;

     (iv) if all or any portion of such Defaulting Bank’s L/C Exposure is
reallocated pursuant to clause (i) above, then the Letter of Credit participation
fees that otherwise would have been payable to such Defaulting Bank pursuant to
Section 2.5(c)(i) with respect to such Defaulting Bank’s reallocated L/C Exposure
shall be payable to the non-Defaulting Banks in accordance with such non-Defaulting
Banks’ Revolving Percentages after giving effect to such reallocation; and

     (v) if all or any portion of such Defaulting Bank’s L/C Exposure is neither
reallocated nor cash collateralized pursuant to clause (i) or (ii) above, then,
without prejudice to any rights or remedies of any Issuing Bank or any other Bank
hereunder, all Letter of Credit participation fees that otherwise would have been
payable to such Defaulting Bank under Section 2.5(c)(i) with respect to such
Defaulting Bank’s unreallocated L/C Exposure shall be payable to the Issuing Banks,
ratably based on the portion of such L/C Exposure attributable to Letters of Credit
issued by each Issuing Bank, until and to the extent that such L/C

36

 

Exposure is reallocated and/or cash collateralized pursuant to clause (i) or (ii) above;

     (d) so long as such Bank is a Defaulting Bank, the Swingline Lender shall not be required to
fund any Swingline Loan and no Issuing Bank shall be required to issue, amend or increase any
Letter of Credit, unless the Swingline Lender is satisfied that the related exposure in respect of
Swingline Loans, and the Issuing Banks are satisfied that the Defaulting Bank’s then outstanding
L/C Exposure, will be 100% covered by the Commitments of the non-Defaulting Banks and, to the
extent such 100% coverage is not achieved, by cash collateral which will be provided by the
Borrower in accordance with Section 2.8(c), and participating interests in any newly made Swingline
Loan or any newly issued or increased Letter of Credit shall be allocated among non-Defaulting
Banks in a manner consistent with Section 2.8(c)(i) (and such Defaulting Bank shall not participate
therein).

     If (i) a Bankruptcy Event with respect to a Parent of any Bank shall occur following the date
hereof and for so long as such event shall continue or (ii) the Swingline Lender or the Issuing
Bank has a good faith belief that any Bank has defaulted in fulfilling its obligations to extend
credit generally (such Bank referenced in clauses (i) and (ii), a “Disregarded Bank”), the
Swingline Lender shall not be required to fund any Swingline Loan and the Issuing Bank shall not be
required to issue, amend or increase any Letter of Credit, unless the Swingline Lender is satisfied
that the related exposure in respect of Swingline Loans, and the Issuing Banks are satisfied that
the Disregarded Bank’s then outstanding L/C Exposure, will be 100% covered by the Commitments of
the non-Disregarded Banks and, to the extent such 100% coverage is not achieved, by cash collateral
which will be provided by the Borrower in the manner consistent with Section 2.8(c), and
participating interests in any newly made Swingline Loan or any newly issued or increased Letter of
Credit shall be allocated among the non-Disregarded Banks in a manner consistent with Section
2.8(c) (and such Disregarded Bank shall not participate therein).

     In the event that the Administrative Agent, the Borrower, the Swingline Lender and the Issuing
Banks each agrees that a Defaulting Bank has adequately remedied all matters that caused such Bank
to be a Defaulting Bank, then the Swingline Exposures and L/C Exposures of the Banks shall be
readjusted to reflect the inclusion of such Bank’s Commitment, and on such date such Bank shall
purchase at par such of the Revolving Loans of the other Banks as the Administrative Agent shall
determine may be necessary in order for such Bank to hold such Revolving Loans in accordance with
its Revolving Percentage.

     The rights and remedies against, and with respect to, a Defaulting Bank under this Section 2.8
are in addition to, and cumulative and not in limitation of, all other rights and remedies that the
Administrative Agent and each Lender, each Issuing Bank, the Swingline Lender or the Borrower may
at any time have against, or with respect to, such Defaulting Bank.

ARTICLE III

PROVISIONS RELATING TO ALL LOANS

     SECTION 3.1. Evidence of Loans. (a) Each Bank shall maintain in accordance with its usual
practice an account or accounts evidencing indebtedness of the Borrower to such Bank

37

 

resulting from each Loan made by such Bank from time to time, including the amounts of principal and interest
payable and paid to such Bank from time to time under this Agreement.

     (b) The Administrative Agent shall maintain the Register pursuant to Section 10.6(d) and a
subaccount therein for each Bank, in which shall be recorded (i) the amount of each Loan made by
each Bank through the Administrative Agent hereunder, the Type thereof and each 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 Bank hereunder and (iii) both the amount of any sum received
by the Administrative Agent hereunder from the Borrower and each Bank’s share thereof.

     (c) The entries made in the Register and the accounts of each Bank maintained pursuant to
Section 3.1(a) shall, to the extent permitted by applicable law, be prima facie
evidence of the existence and amount of the obligations of the Borrower therein recorded;
provided, however, that the failure of any Bank or the Administrative Agent to
maintain the Register or any such account, or any error therein, shall not in any manner affect the
obligation of the Borrower to repay (with applicable interest) the Loans actually made to the
Borrower by such Bank in accordance with the terms of this Agreement.

     (d) Any Bank may request that the Loans made by such Bank be evidenced by a Note. In such
event, the Borrower shall prepare, execute and deliver to such Bank a Note payable to such Bank.

     SECTION 3.2. Fees. (a) The Borrower agrees to pay to the Administrative Agent for the account of
each Bank a commitment fee (the “Commitment Fee”), which shall accrue at the Applicable
Rate on the Available Commitment of such Bank on each day during the period from the date hereof to
the Termination Date. The accrued Commitment Fees shall be payable (i) quarterly in arrears on the
last day of each March, June, September and December until the Termination Date and (ii) on the
Termination Date.

     (b) The Commitment Fees shall be calculated by the Administrative Agent on the basis of a 365-
or 366-day year, as the case may be, for the actual days (including the first day but excluding the
last day) occurring in the period for which such Commitment Fees are payable.

     (c) The Borrower shall pay to the Administrative Agent, for its own account, the fees in the
amounts and on the dates previously agreed to in writing by the Borrower and the Administrative
Agent.

     SECTION 3.3. Interest. The Borrower shall pay interest on the unpaid principal amount of each Loan
made by each Bank from the date of such Loan until such principal amount shall be paid in full, at
the times and at the rates per annum set forth below:

     (a) ABR Loans. Each ABR Loan (excluding each Swingline Loan) shall bear interest at a
rate per annum equal at all times to the lesser of (i) the Alternate Base Rate plus the
Applicable Rate and (ii) the Highest Lawful Rate, payable quarterly in arrears on the last day of
each March, June, September and December and on the Termination Date.

38

 

     (b) Eurodollar Rate Loans. Each Eurodollar Rate Loan shall bear interest at a rate
per annum equal at all times to the lesser of (i) the sum of the Eurodollar Rate for the applicable
Interest Period for such Loan plus the Applicable Rate and (ii) the Highest Lawful Rate,
payable on the last day of such Interest Period and, with respect to Interest Periods of six months
or longer, on the ninetieth (90th) day after the commencement of the Interest Period and on each
succeeding ninetieth (90th) day during such Interest Period, and on the Termination Date. In
addition, interest on each Eurodollar Rate Loan will be payable upon any payment or prepayment of
such Eurodollar Rate Loan.

     (c) Swingline Loans. Each Swingline Loan shall bear interest at a rate per annum
equal to the lesser of (i)(A) the Alternate Base Rate plus the Applicable Rate or (B) the
Money Market Rate, at the election of the Borrower pursuant to Section 2.4, and (ii) the Highest
Lawful Rate, payable quarterly in arrears on the last day of each March, June, September and
December and on the date of payment of such Swingline Loan.

     (d) Calculations. Interest that is determined by reference to the Alternate Base Rate
(to the extent based on the Prime Rate) shall be calculated by the Administrative Agent on the
basis of a 365- or 366-day year, as the case may be, for the actual days (including the first day
but excluding the last day) occurring in the period in which such interest is payable and otherwise
shall be calculated by the Administrative Agent on the basis of a 360-day year for the actual days
(including the first day and excluding the last day) occurring in the period for which such
interest is payable.

     (e) Default Rate. Notwithstanding the foregoing, if all or a portion of (i) the
principal amount of any Loan or Reimbursement Obligation, (ii) any interest payable thereon, or
(iii) any Commitment Fee or other amount payable hereunder shall not be paid when due (whether at
the stated maturity, by acceleration or otherwise), such overdue amount shall bear interest,
payable from time to time on demand, at a rate per annum equal to the lesser of (A) the Highest
Lawful Rate and (B) the Default Rate, in each case from the date of such non-payment until such
amount is paid in full (after as well as before judgment).

     (f) Determination Conclusive. Each determination of an interest rate by the
Administrative Agent pursuant to any provisions of this Agreement shall be conclusive and binding
on the Borrower and the Banks in the absence of manifest error. The Administrative Agent shall, at
the request of the Borrower, deliver to the Borrower a statement showing in
reasonable detail the quotations used by the Administrative Agent in determining the
Eurodollar Rate.

     SECTION 3.4. Reserve Requirements. (a) The Borrower agrees to pay to each Bank that requests
compensation under this Section 3.4 in accordance with the provisions set forth in Section 4.8(b),
so long as such Bank shall be required to maintain reserves against “Eurocurrency liabilities”
under Regulation D of the Board (or, so long as such Bank shall be required by the Board or by any
other Governmental Authority to maintain reserves against any other category of liabilities that
includes deposits by reference to which the interest rate on Eurodollar Rate Loans is determined as
provided in this Agreement or against any category of extensions of credit or other assets of such
Bank that includes any Eurodollar Rate Loans), an additional amount (determined by such Bank and
notified to the Borrower pursuant to the

39

 

provisions set forth in Section 4.8(b)) representing such
Bank’s calculation or, if an accurate calculation is impracticable, reasonable estimate (using such
method of allocation to such Loans of the Borrower as such Bank shall determine in accordance with
Section 4.8(a)) of the actual costs, if any, incurred by such Bank during the relevant Interest
Period as a result of the applicability of the foregoing reserves to such Eurodollar Rate Loans,
which amount in any event shall not exceed the product of the following for each day of such
Interest Period:

     (i) the principal amount of the relevant Eurodollar Rate Loans made by such Bank
outstanding on such day;

     (ii) the difference between (A) a fraction, the numerator of which is the Eurodollar
Rate (expressed as a decimal) applicable to such Eurodollar Rate Loan (expressed as a
decimal), and the denominator of which is one minus the maximum rate (expressed as a
decimal) at which such reserve requirements are imposed by the Board or other Governmental
Authority on such date, minus (B) such numerator; and

     (iii) a fraction, the numerator of which is one and the denominator of which is 360.

     (b) The agreements in this Section 3.4 shall survive the termination of this Agreement and the
payment of all amounts payable hereunder; provided, however, that in no event shall
the Borrower be obligated to reimburse or compensate any Bank for amounts contemplated by this
Section 3.4 for any period prior to the date that is 90 days before the date upon which such Bank
requests in writing such reimbursement or compensation from the Borrower.

     SECTION 3.5. Interest Rate Determination and Protection. (a) The rate of interest for each
Eurodollar Rate Loan shall be determined by the Administrative Agent two Business Days before the
first day of each Interest Period applicable to such Loan. The Administrative Agent shall give
prompt notice to the Borrower and the Banks of the applicable interest rate determined by the
Administrative Agent for purposes of Sections 3.3(a) and (b) hereof.

     (b) If, prior to the first day of any Interest Period for a Borrowing of Eurodollar Rate
Loans, (i) the Administrative Agent shall have reasonably determined (which determination shall be
conclusive and binding upon the Borrower absent manifest error) that, by reason of circumstances
affecting the London interbank Eurodollar market, adequate and reasonable means do not exist for
ascertaining the Eurodollar Rate for such Interest Period or (ii) the Administrative Agent shall
have received notice from the Majority Banks that the Eurodollar Rate determined or to be
determined for such Interest Period will not adequately and fairly reflect the cost to such Banks
(as determined in good faith and certified by such Banks) of making or maintaining their Eurodollar
Rate Loans included in such Borrowing during such Interest Period, the Administrative Agent shall
give written notice thereof to the Borrower and the Banks as soon as practicable thereafter. If
such notice is given, (A) any Eurodollar Rate Loans requested to be made on the first day of such
Interest Period shall be made as ABR Loans, (B) any Loans that were to have been converted on the
first day of such Interest Period to Eurodollar Rate Loans shall be continued as ABR Loans and (C)
any outstanding Eurodollar Rate Loans shall be converted, on the last day of the then applicable
Interest Period, to ABR Loans. Until such notice has been withdrawn by the Administrative Agent,
no further Eurodollar

40

 

Rate Loans shall be made or continued as such, nor shall the Borrower have
the right to convert ABR Loans to Eurodollar Rate Loans. The Administrative Agent will withdraw
any such notice when the circumstances giving rise to such notice no longer exist.

     SECTION 3.6. Voluntary Interest Conversion or Continuation of Revolving Loans. (a) Each Borrowing
initially shall be of the Type specified in the applicable Notice of Borrowing and, in the case of
a Borrowing of Eurodollar Rate Loans, shall have an initial Interest Period as specified in such
Notice of Borrowing. Thereafter, the Borrower may, at any time and from time to time, but subject
to Section 3.7 below, elect to (i) convert Revolving Loans of one Type into Revolving Loans of
another Type; (ii) convert Eurodollar Rate Loans for a specified Interest Period into Eurodollar
Rate Loans for a different Interest Period; or (iii) continue Eurodollar Rate Loans for a specified
Interest Period as Eurodollar Rate Loans for the same Interest Period; provided,
however, that (A) if an Event of Default has occurred and is continuing and the
Administrative Agent, at the request of the Majority Banks, so notifies the Borrower, then, so long
as an Event of Default is continuing, no Revolving Loan may be converted into or continued as a
Eurodollar Rate Loan, and (B) no Revolving Loan may be converted into or continued as a Eurodollar
Rate Loan if after giving effect thereto, Section 2.3 would be contravened. This Section shall not
apply to Swingline Borrowings, which may not be converted or continued.

     (b) To make an election pursuant to this Section, the Borrower shall notify the Administrative
Agent of such request by telephone, facsimile or e-mail (i) not later than 11:00 A.M. (New York
City time) on the third Business Day prior to the date of the proposed interest conversion or
continuation in the case of a conversion into or continuation of a Eurodollar Rate Loan and (ii)
not later than 11:00 A.M. (New York City time) on the Business Day preceding the proposed interest
conversion in the case of a conversion into an ABR Loan. Each telephonic notice of interest
conversion/continuation given by the Borrower under this Section 3.6(a), shall be irrevocable and
shall be confirmed promptly thereafter in writing.

     (c) Each written notice of interest conversion/continuation given by the Borrower under this
Section 3.6(a) and each confirmation of an oral notice of interest conversion/continuation given by
the Borrower under this Section 3.6(a) shall be in substantially the form of Exhibit B
hereto (“Notice of Interest Conversion/Continuation”). Each such Notice of Interest
Conversion/Continuation shall specify therein (x) the requested date of such interest conversion or
continuation; (y) the Revolving Loans to be converted or continued; and (z) if such interest
conversion or continuation involves the conversion into or continuation as Eurodollar Rate Loans,
the duration of the Interest Period for each such Eurodollar Rate Loan. If any Notice of Interest
Conversion/Continuation requests a conversion into or continuation as Eurodollar Rate Loans but
does not specify an Interest Period for such Eurodollar Rate Loans, the Borrower shall be deemed to
have selected an Interest Period of one month’s duration. Upon receipt of any such Notice of
Interest Conversion/Continuation, the Administrative Agent shall promptly notify each Bank thereof.
Each Notice of Interest Conversion/ Continuation shall be irrevocable and binding on the Borrower.

     (d) If the Borrower shall fail to deliver to the Administrative Agent a Notice of Interest
Conversion/Continuation with respect to any Borrowing of Eurodollar Rate Loans by 11:00 A.M. (New
York City time) on the third Business Day prior to the last day of the Interest

41

 

Period applicable thereto in accordance with this Section 3.6, the Administrative Agent will forthwith so notify the
Borrower and the Banks (provided that the failure to give such notice shall not affect the
conversion referred to below) and, unless such Revolving Loans are repaid as provided herein, such
Revolving Loans will automatically, on the last day of the then existing Interest Period therefor,
convert into Eurodollar Rate Loans with a one month Interest Period.

     SECTION 3.7. Funding Losses Relating to Eurodollar Rate Loans(a) The Borrower agrees, without
duplication of any other provision under this Agreement, to indemnify each Bank and to hold each
Bank harmless from any loss or expense that such Bank may sustain or incur as a consequence of (i)
default by the Borrower in payment when due of the principal amount of or interest on any
Eurodollar Rate Loan, (ii) default by the Borrower in making a borrowing of, conversion into or
continuation of any Eurodollar Rate Loan after the Borrower has given a notice requesting the same
in accordance with the provisions of this Agreement, (iii) default by the Borrower in making any
prepayment of Eurodollar Rate Loans after the Borrower has given a notice thereof in accordance
with the provisions of this Agreement or (iv) the making of a prepayment of Eurodollar Rate Loans
or the conversion of Eurodollar Rate Loans into ABR Loans, on a day that is not the last day of an
Interest Period with respect thereto or a day that is not the scheduled maturity date with respect
thereto, including in each case, any such loss or expense arising from the reemployment of funds
obtained by such Bank or from fees payable to terminate the deposits from which such funds were
obtained. The calculation of all amounts payable to a Bank under this Section 3.7(a) shall be made
pursuant to the method described in Section 4.8(a), but in no event shall such amounts payable with
respect to any Eurodollar Rate Loan exceed the amounts that would have been payable assuming such
Bank had actually funded its relevant Eurodollar Rate Loan through the purchase of a deposit
bearing interest at the applicable Eurodollar Rate in an amount equal to the amount of such
Eurodollar Rate Loan and having a maturity comparable to the Interest Period applicable to such
Eurodollar Rate Loan; provided that each Bank may fund each of its
Eurodollar Rate Loans in any manner it sees fit, and the foregoing assumption shall be
utilized only for the calculation of amounts payable under this Section 3.7(a).

     (b) The agreements in this Section 3.7 shall survive the termination of this Agreement and the
payment of all amounts payable hereunder; provided, however, that in no event shall
the Borrower be obligated to reimburse or compensate any Bank for amounts contemplated by this
Section 3.7 for amounts accruing prior to the date that is 90 days prior to the date upon which
such Bank requests in writing such reimbursement or compensation from the Borrower.

     SECTION 3.8. Change in Legality. (a) Notwithstanding any other provision of this Agreement, if
any Bank shall notify the Administrative Agent that it has determined in good faith that the
introduction of or any change in or in the interpretation or application of any law or regulation
by any Governmental Authority (in each case occurring after the date of this Agreement) makes it
unlawful, or any central bank or other Governmental Authority asserts after the date of this
Agreement that it is unlawful, for any Bank or its applicable lending office to perform its
obligations hereunder to make Eurodollar Rate Loans or to fund or maintain Eurodollar Rate Loans
hereunder, (i) the obligation of such Bank to make, or to convert Revolving Loans into, or to
continue Eurodollar Rate Loans as, Eurodollar Rate Loans shall be suspended until the
Administrative Agent shall notify the Borrower that the circumstances causing such suspension no
longer exist; (ii) the Borrower shall, at its option, either prepay in

42

 

full all Eurodollar Rate
Loans of such Bank then outstanding, or convert all such Revolving Loans to ABR Loans, on the
respective last days of the then current Interest Periods with respect to such Revolving Loans (or
within such earlier period as required by law), accompanied, in the case of any prepayments, by
interest accrued thereon and any amounts payable under Section 3.7(a). Each Bank agrees that it
will use reasonable efforts to designate a different lending office for the Eurodollar Rate Loans
due to such Bank that are affected by this Section 3.8, if such designation will avoid the
illegality described in this Section 3.8 so long as such designation will not be disadvantageous to
such Bank as determined by such Bank in its sole discretion acting in good faith.

     (b) For purposes of this Section 3.8, a notice to the Borrower (with a copy to the
Administrative Agent) by any Bank pursuant to paragraph (a) above shall be effective on the date of
receipt thereof by the Borrower.

ARTICLE IV

INCREASED COSTS, TAXES, PAYMENTS AND PREPAYMENTS

     SECTION 4.1. Increased Costs; Capital Adequacy. (a) If, after the date of this Agreement, the
adoption of or any change in any law or regulation or in the interpretation or application thereof
by any Governmental Authority or compliance by any Bank with any request or directive (whether or
not having the force of law) from any central bank or other Governmental Authority made subsequent
to the date of this Agreement (provided that the Dodd-Frank Wall Street Reform and Consumer
Protection Act, Basel III and all requests, rules, guidelines or directives under, or issued in
connection with, the
foregoing shall be deemed to be a change in requirements of law, regardless of the date
enacted, adopted or issued):

     (i) shall subject any Bank or Issuing Bank to any tax of any kind whatsoever with
respect to this Agreement, any Letter of Credit or any Application made by it, or change the
basis of taxation of payments to such Bank or Issuing Bank in respect thereof (except for
Indemnified Taxes or Other Taxes covered by Section 4.3 and the imposition of, or any change
in the rate of, any Excluded Tax);

     (ii) shall impose, modify or hold applicable any reserve, special deposit, compulsory
loan or similar requirement against assets held by, deposits or other liabilities in or for
the account of, advances, loans or other extensions of credit by, or any other acquisition
of funds by, any office of such Bank that is not otherwise included in the determination of
the Eurodollar Rate hereunder (except for amounts covered by Section 3.4 or any other
Section hereof); or

     (iii) shall impose on such Bank any other condition;

and the result of any of the foregoing is to increase the actual cost to such Bank, by an amount
that such Bank deems to be material, of making, converting into, continuing or maintaining
Eurodollar Rate Loans or issuing or participating in Letters of Credit or to reduce any amount
receivable hereunder in respect thereof, then, in any such case, the Borrower shall promptly pay
such Bank, upon its demand in the manner set forth in Section 4.8(b), any additional amounts,

43

 

computed by such Bank in accordance with Section 4.8(a), necessary to compensate such Bank for such
actual increased cost or reduced amount receivable that is attributable to Loans or Commitments (to
the extent that such Bank has not already been compensated or reimbursed for such amounts pursuant
to any other provision of this Agreement). If any Bank becomes entitled to claim any additional
amounts pursuant to this Section 4.1(a) from the Borrower, it shall promptly notify the Borrower,
through the Administrative Agent, of the event by reason of which it has become so entitled in the
manner set forth in Section 4.8(b).

     (b) If any Bank determines in good faith that the introduction of or any change in or in the
interpretation or application by any Governmental Authority of any law or regulation regarding
capital adequacy after the date of this Agreement or compliance by such Bank or any corporation
controlling such Bank with any law or regulation or any guideline or request from any central bank
or other Governmental Authority (whether or not having the force of law) made or issued after the
date of this Agreement does or shall have the effect, as a result of such Bank’s obligations under
this Agreement or under any Letter of Credit, of reducing the rate of return on such Bank’s or such
corporation’s capital to a level below that which such Bank or such corporation could have achieved
but for such change or compliance (taking into consideration such Bank’s or such corporation’s
policies with respect to capital adequacy) by an amount deemed by such Bank to be material, the
Borrower shall pay to the Administrative Agent for the account of such Bank, from time to time as
specified by such Bank in the manner set forth in Section 4.8(b), additional amounts, computed by
such Bank in accordance with Section 4.8(a), sufficient to compensate such Bank or such corporation
in the light of such circumstances, to the extent that such Bank reasonably determines such
reduction in rate of return is allocable to the existence of such Bank’s obligations hereunder.

     (c) The agreements contained in this Section 4.1 shall survive the termination of this
Agreement and the payment of all amounts payable hereunder; provided, however, that
in no event shall the Borrower be obligated to reimburse or compensate any Bank for amounts
contemplated by this Section 4.1 for any period prior to the date that is 90 days prior to the date
upon which such Bank requests in writing such reimbursement or compensation from the Borrower;
provided that, to the extent that the adoption of or any change in any law or regulation or
in the interpretation or application thereof gives rise to any amount(s) contemplated by this
Section 4.1 on a retroactive basis, then the 90-day period referred to in the preceding proviso
shall be extended to include the period of retroactive effect thereof.

     SECTION 4.2. Pro Rata Treatment and Payments and Computations. (a) Each Borrowing of Loans by the
Borrower from the Banks hereunder, each payment by the Borrower on account of any commitment or
other fee, any reduction of the Commitments of the Banks and any prepayment on account of principal
and interest on the Loans shall be made pro rata according to the respective
Revolving Percentages of the Banks.

     (b) The Borrower shall make each payment (including each prepayment) hereunder, whether on
account of principal, interest, fees or otherwise, without setoff or counterclaim, not later than
12:00 Noon (New York City time) on the day when due in Dollars to the Administrative Agent at the
Funding Office in immediately available funds, except payments to be made directly to the Swingline
Lender as expressly provided herein. The Administrative Agent will promptly thereafter cause to be
distributed like funds relating to the payment of

44

 

principal, interest, Letter of Credit fees or
commitment or other fees (to the extent received by the Administrative Agent) ratably to the Banks
according to the amounts of their respective Loans, L/C Obligations and Commitments in respect of
which such payment is made, and like funds relating to the payment of any other amount payable to
any Bank (to the extent received by the Administrative Agent) to such Bank, in each case to be
applied in accordance with the terms of this Agreement.

     (c) Whenever any payment hereunder or under the Notes shall be stated to be due on a day other
than a Business Day, such payment shall be made on the next succeeding Business Day, and such
extension of time shall in such case be included in the computation of payment of interest or fees,
as the case may be; provided, however, if such extension would cause payment of
interest on or principal of Eurodollar Rate Loans to be made in the next following calendar month,
such payment shall be made on the next preceding Business Day.

     (d) Unless the Administrative Agent shall have received notice from the Borrower prior to the
date on which any payment is due to the Banks hereunder that the Borrower will not make such
payment in full, the Administrative Agent may assume that the Borrower has made such payment in
full to the Administrative Agent on such date and the Administrative Agent may, in reliance upon
such assumption, cause to be distributed to each Bank on such due date an amount equal to the
amount then due such Bank. If and to the extent the Borrower shall not have so made such payment in
full to the Administrative Agent, each Bank shall pay to the Administrative Agent on demand an
amount equal to the product of (i) the daily average Federal Funds Effective Rate during such
period, times (ii) the amount of such Bank’s Revolving Percentage of such payment, times (iii) a
fraction, the numerator of which is the number of days
that elapse from and including the date such amount is distributed to such Bank to the date on
which such Bank’s Revolving Percentage of such payment shall have become immediately available to
the Administrative Agent and the denominator of which is 360.

     (e) If any Bank shall fail to make any payment required to be made by it pursuant to Section
2.4(a), 2.5(a) or (e) or 9.7, then the Administrative Agent may, in its discretion and
notwithstanding any contrary provision hereof, (i) apply any amounts thereafter received by the
Administrative Agent for the account of such Bank for the benefit of the Administrative Agent, the
Swingline Lender or the Issuing Bank to satisfy such Bank’s obligations to it under such Section
until all such unsatisfied obligations are fully paid, and/or (ii) hold any such amounts in a
segregated account as cash collateral for, and application to, any future funding obligations of
such Bank under any such Section, in the case of each of clauses (i) and (ii) above, in any order
as determined by the Administrative Agent in its discretion.

     SECTION 4.3. Taxes. (a) Except as otherwise required by any requirement of law, any and all
payments by or on behalf of the Borrower hereunder or under any other Loan Document shall be made
free and clear of and without deduction or withholding for or on account of any and all present or
future taxes, levies, imposts, duties, charges, fees, deductions or withholdings, and all interest,
penalties and additions to tax with respect thereto, now or hereafter imposed, levied, collected,
withheld or assessed by any Governmental Authority (“Taxes”), excluding, in the case of
each Bank, the Administrative Agent, any Issuing Bank or any other recipient of any payment to be
made by or on account of any obligation of the Borrower hereunder or under any other Loan Document,
(i) net income Taxes, branch profits Taxes and franchise Taxes imposed

45

 

on it by any jurisdiction
under the laws of which such recipient is organized, or in which its principal office is located
(or, in the case of any Bank, in which its applicable lending office is located), or imposed as a
result of a present or former connection between it and the jurisdiction (or political subdivision
or taxing authority thereof or therein) imposing such Tax (other than a connection arising solely
from such recipient having executed, delivered or performed its obligations or received a payment
under, or enforced, this Agreement or any other Loan Document), (ii) in the case of a Bank (other
than an assignee pursuant to a request by the Borrower under Section 4.7(b)), any U.S. Federal
withholding Taxes resulting from any requirement of law in effect on the date such Bank becomes a
party to this Agreement (or designates a new lending office), except to the extent that any such
Bank (or its assignor, if any) was entitled, at the time of designation of a new lending office (or
assignment), to receive additional amounts from the Borrower with respect to such Taxes pursuant to
this Section 4.3(a), (iii) United States backup withholding Taxes, (iv) Taxes attributable to its
failure to comply with Section 4.3(e) or Section 4.3(f), and (v) any U.S. withholding Taxes imposed
under FATCA (all such non-excluded Taxes imposed on or with respect to any payment made by or on
account of any obligation of the Borrower under any Loan Document being hereinafter referred to as
“Indemnified Taxes,” and all such excluded Taxes being hereinafter referred to as
“Excluded Taxes”). If the Borrower shall be required by law to deduct or withhold any
Taxes from or in respect of any sum payable hereunder or under any other Loan Document to any Bank
or the Administrative Agent, (i) to the extent such Taxes are Indemnified Taxes or Other Taxes, the
sum payable by the Borrower shall be increased as necessary so that after making all required
deductions (including deductions applicable to additional sums payable under this Section 4.3) the
Bank or the Administrative
Agent (as the case may be) receives an amount equal to the sum it would have received had no
such deductions for Indemnified Taxes or Other Taxes 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. Whenever any Taxes or Other Taxes are payable by the
Borrower pursuant to this Section 4.3, as promptly as possible thereafter the Borrower shall send
to the Administrative Agent for the account of the relevant Bank or Administrative Agent, as the
case may be, either (A) within thirty (30) days after payment of any applicable tax, official tax
receipts or notarized copies of such receipts evidencing such payment or (B) a certificate executed
by a Responsible Officer of the Borrower confirming that such Taxes or Other Taxes have been paid,
together with evidence of such payment.

     (b) In addition, the Borrower agrees to pay, in accordance with applicable law, any present or
future stamp or documentary Taxes or any other excise or property Taxes, charges or similar levies
that arise from any payment made hereunder or under any Note or from the execution, delivery,
registration or enforcement of or otherwise with respect to, this Agreement, any other Loan
Document, or the Loans and for which such Bank or the Administrative Agent (as the case may be) has
not been otherwise reimbursed by the Borrower under this Agreement (hereinafter referred to as
“Other Taxes”).

     (c) The Borrower will indemnify each Bank and the Administrative Agent for the full amount of
Indemnified Taxes or Other Taxes (including any Indemnified Taxes or Other Taxes imposed by any
jurisdiction on amounts payable under this Section 4.3) paid by such Bank or the Administrative
Agent (as the case may be) and any reasonable expenses arising therefrom or

46

 

with respect thereto, whether or not such Indemnified Taxes or Other Taxes were correctly or legally imposed or asserted
by the relevant Governmental Authority.

     (d) Each Bank shall indemnify the Administrative Agent for the full amount of any Indemnified
Taxes or Other Taxes that are attributable to such Bank and that are payable or paid by the
Administrative Agent, together with all reasonable costs and expenses arising therefrom or with
respect thereto, as determined by the Administrative Agent in good faith. A certificate as to the
amount of such payment or liability delivered to any Bank by the Administrative Agent shall be
conclusive absent manifest error.

     (e)

     (i) Each Bank (which, for purposes of this Section 4.3(e) and Section 4.3(f), shall
include any Issuing Bank) that is a “United States Person” as defined in Section 7701(a)(30)
of the Code shall deliver to the Borrower and the Administrative Agent on or before the date
on which it becomes a party to this Agreement two properly completed and duly executed
copies of IRS Form W-9 (or any successor form) certifying that such Bank is exempt from U.S.
federal withholding tax.

     (ii) Each Bank (or Transferee, if applicable) that is not a U.S. Person as defined in
Section 7701(a)(30) of the Code (a “Non-U.S. Bank”) agrees that it will deliver to
the Borrower and the Administrative Agent (or, in the case of a Participant, to the Bank
from which the related participation shall have been purchased) (i) two duly
completed and properly executed copies of IRS Form W-8BEN, W-8ECI, W-8EXP or W-8IMY
(together with any applicable underlying IRS forms or other applicable documentation) or any
successor applicable form, as the case may be, (ii) in the case of a Non-U.S. Bank claiming
exemption from U.S. federal withholding tax under Section 871(h) or 881(c) of the Code with
respect to payments of “portfolio interest,” a statement substantially in the form of
Exhibit G and the applicable IRS Form W-8, or any subsequent versions thereof or
successors thereto, properly completed and duly executed by such Non-U.S. Bank claiming
complete exemption from, or a reduced rate of, U.S. federal withholding tax on payments
under this Agreement and the other Loan Documents, or (iii) any other form prescribed by
applicable requirements of U.S. federal income tax law as a basis for claiming exemption
from or a reduction in U.S. federal withholding tax duly completed together with such
supplementary documentation as may be prescribed by applicable requirements of law to permit
the Borrower and the Administrative Agent to determine the withholding or deduction required
to be made. Such forms shall be delivered by each Non-U.S. Bank on or before the date which
it becomes a party to this Agreement (or, in the case of any Participant, on or before the
date such Participant purchases the related participation) and from time to time thereafter
upon the request of the Borrower or the Administrative Agent. In addition, each Non-U.S.
Bank also agrees to deliver to the Borrower and the Administrative Agent two further copies
of the said Form W-8BEN, W-8ECI, W-8EXP, or W-8IMY (together with any applicable underlying
IRS forms or other applicable documentation) or any successor applicable form, as the case
may be, on or before the date that any such form expires or becomes obsolete or after the
occurrence of any event requiring a change in the most recent form or certification
previously delivered by it to the Borrower. Each Non-U.S.

47

 

Bank shall promptly notify the
Borrower and the Administrative Agent at any time it determines that it is no longer in a
position to provide any previously delivered certificate to the Borrower (or any other form
of certification adopted by the U.S. taxing authorities for such purpose). Notwithstanding
any other provision of this Section 4.3(e), a Non-U.S. Bank shall not be required to deliver
any form pursuant to this Section 4.3(e) that such Non-U.S. Bank is not legally able to
deliver.

     (iii) If a payment made to a Bank under any Loan Document would be subject to U.S.
Federal withholding Tax imposed by FATCA if such Bank were to fail to comply with the
applicable reporting requirements of FATCA (including those contained in Section 1471(b) or
1472(b) of the Code, as applicable), such Bank shall deliver to the Borrower and the
Administrative Agent, at the time or times prescribed by law and at such time or times
reasonably requested by the Borrower or the Administrative Agent, such documentation
prescribed by applicable law (including as prescribed by Section 1471(b)(3)(C)(i) of the
Code) and such additional documentation reasonably requested by the Borrower or the
Administrative Agent as may be necessary for the Borrower or the Administrative Agent to
comply with its obligations under FATCA, to determine that such Bank has or has not complied
with such Bank’s obligations under FATCA or to determine the amount to deduct and withhold
from such payment. Solely for purposes of this Section 4.3(e), “FATCA” shall include any
amendments made to FATCA after the date of this Agreement.

     (f) Without limiting Section 4.3(e), a Bank 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 or reasonably requested by the Borrower or the Administrative Agent, such
properly completed and executed documentation prescribed by applicable law as will permit such
payments to be made without withholding or at a reduced rate if such Bank is legally entitled to
complete, execute and deliver such documentation; provided that a Bank shall not be
required to provide such documentation (other than such documentation set forth in Section 4.3(e))
if in such Bank’s reasonable judgment such completion, execution or submission would materially
prejudice the legal or commercial position of such Bank.

     (g) If the Administrative Agent or any Bank determines, in its sole discretion exercised in
good faith, that it has received a refund of those Taxes or Other Taxes as to which it has been
indemnified by the Borrower (including by the payment of additional amounts pursuant to this
Section 4.3), the Administrative Agent or such Bank shall within 20 days after such refund pay to
the Borrower the amount of such refund to the extent that the Borrower indemnified the
Administrative Agent or such Bank for such Taxes or Other Taxes pursuant to this Section 4.3, net
of any out-of-pocket costs of the Administrative Agent or such Bank 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 Bank,
agrees to repay the amount paid over to the Borrower pursuant to this Section 4.3(g) (plus any
penalties, interest or other charges imposed by the relevant Governmental Authority) to the
Administrative Agent or such Bank in the event the Administrative Agent or such Bank is required to
repay such refund to such Governmental

48

 

Authority. This paragraph shall not be construed to require
the Administrative Agent or any Bank 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.

     (h) The agreements in this Section 4.3 shall survive the termination of this Agreement and the
payment of all amounts payable hereunder; provided, however, that (i) in no event
shall the Borrower be obligated to reimburse or compensate any Bank for amounts contemplated by
this Section 4.3 for any period before the date that is 120 days before the date upon which such
Bank requests in writing such reimbursement or compensation from the Borrower (other than any
amounts as to which the ultimate amount of the reimbursement due could not then be determined) and
(ii) nothing contained in this Section 4.3 shall require the Borrower to pay any amount to any Bank
or the Administrative Agent in addition to that for which it has already reimbursed any Bank or the
Administrative Agent under any other provision of this Agreement.

     SECTION 4.4. Sharing of Payments, Etc. If any Bank (a “Benefitted Bank”) shall at any time
receive any payment (other than pursuant to Section 2.7, 3.4, 3.7, 4.1 or 4.3) of all or part of
its Revolving Loans, Reimbursement Obligations or participations in Swingline Loans owing to it or
interest thereon, or receive any collateral in respect thereof (whether voluntarily or
involuntarily, by setoff, pursuant to events or proceedings of the nature referred to in Section
8.1(g) or 8.1(h), or otherwise), in a greater proportion than any such payment to or collateral
received by any other Bank, if any, in respect
of such other Bank’s Loans, Reimbursement Obligations owing to it, respectively, or interest
thereon, such benefitted Bank shall purchase for cash from the other Banks a participating interest
in such portion of each such other Bank’s Loans or Reimbursement Obligations owing to it,
respectively, or shall provide such other Banks with the benefits of any such collateral, or the
proceeds thereof, as shall be necessary to cause such benefitted Bank to share the excess payment
or benefits of such collateral or proceeds ratably with each of the Banks; provided,
however, that if all or any portion of such excess payment or benefits is thereafter
recovered from such benefitted Bank, such purchase shall be rescinded, and the purchase price and
benefits returned, to the extent of such recovery, but without interest. The Borrower agrees that
any Bank so purchasing a participation from another Bank pursuant to this Section 4.4 may, to the
fullest extent permitted by law, exercise all its rights of payment (including the right of setoff)
with respect to such participation as fully as if such Bank were the direct creditor of the
Borrower in the amount of such participation.

     SECTION 4.5. Optional Termination or Reduction of the Commitments. (a) Unless previously
terminated, the Commitments of the Banks to make Loans shall terminate on the Termination Date.

     (b) The Borrower shall have the right, without penalty or premium, upon at least three (3)
Business Days’ irrevocable written notice to the Administrative Agent (which shall give prompt
notice to each Bank), to terminate in whole the Commitments or permanently, from time to time, to
reduce ratably in part the unused portion of the Commitments, provided that (i) each
partial reduction shall be in the aggregate principal amount of $5,000,000 or an integral multiple
of $1,000,000 in excess thereof, (ii) no such termination or reduction shall be permitted if, after
giving effect thereto and to any prepayments made under Section 4.6 by the Borrower on the
effective date thereof, the Total Outstanding Extensions of Credit then outstanding would exceed
the Total Commitments then in effect, and (iii) any notice of termination of the Commitments

49

 

may state that such notice is conditioned upon the effectiveness of other credit facilities or the
closing of one or more securities offerings, in which case such notice may be revoked by the
Borrower (by notice to the Administrative Agent on or prior to the specified date) if such
condition is not satisfied.

          Each reduction of Commitments pursuant to this Section 4.5 shall be applied pro rata to the
Commitments of each Bank. If at any time, including after giving effect to any reduction of
Commitments pursuant to this Section 4.5, the Total Outstanding Extensions of Credit exceed the
Total Commitments, the Borrower shall be obligated, first, to prepay the Loans in the
amount of such excess, second, to cash collateralize Letters of Credit to the extent that
the aggregate amount of the L/C Obligations exceeds such Total Commitments after prepayment of all
Loans.

     SECTION 4.6. Voluntary Prepayments. The Borrower may, upon written notice delivered to the
Administrative Agent (and, in the case of prepayment of a Swingline Loan, the Swingline Lender) (i)
not later than 11:00 A.M. (New York City time) on the same Business Day, in the case of a
prepayment of ABR Revolving Loans, (ii) no later than 11:00 A.M. (New York City time) two (2)
Business Days before the date of prepayment (or such shorter or no notice as may be satisfactory to the
Administrative Agent), in the case of a prepayment of Eurodollar Rate Loans, and (iii) not later
than 12:00 Noon (New York City time) on the date of prepayment, in the case of a prepayment of a
Swingline Loan, stating the aggregate principal amount of the prepayment and the Loans to be
prepaid, prepay the outstanding principal amounts of such Loans comprising part of the same
Borrowing in whole or ratably in part, together with accrued interest to the date of such
prepayment on the principal amount prepaid to the extent required by Section 3.3; provided,
however, that losses incurred by any Bank under Section 3.7 shall be payable with respect
to each such prepayment in the manner set forth in Section 3.7. Any such notice provided pursuant
to this Section 4.6 shall be irrevocable; provided that, if a notice of prepayment is given
in connection with a conditional notice of termination of the Commitments as contemplated by
Section 4.5(b)(iii), then such notice of prepayment may be revoked if such notice of termination is
revoked in accordance with Section 4.5(b)(iii). Partial prepayments pursuant to this Section 4.6
with respect to any Tranche of Eurodollar Rate Loans shall be in an aggregate principal amount
equal to the lesser of (a) $5,000,000 or an integral multiple of $1,000,000 in excess thereof and
(b) the aggregate principal amount of such Tranche of Eurodollar Rate Loans then outstanding, as
the case may be; provided that no partial prepayment of any Tranche of Eurodollar Rate
Loans may be made if, after giving effect thereto, Section 2.1(b) would be contravened. Partial
prepayments with respect to ABR Revolving Loans (other than Swingline Loans) shall be made in an
aggregate principal amount equal to the lesser of (i) $1,000,000 or an integral multiple of
$500,000 in excess thereof and (ii) the aggregate principal amount of ABR Revolving Loans then
outstanding, as the case may be.

     SECTION 4.7. Mitigation of Losses and Costs; Replacement of Banks. (a) Any Bank claiming
reimbursement from the Borrower under any of Sections 3.4, 3.7, 4.1 and 4.3 hereof shall use
reasonable efforts (including, if requested by the Borrower, reasonable efforts to designate a
different lending office of such Bank) to mitigate the amount of such losses, costs, expenses and
liabilities, if such efforts can be made and such mitigation can be accomplished without such Bank
suffering (i) any economic disadvantage for which such Bank does not

50

 

receive full indemnity from the Borrower under this Agreement or (ii) any legal or regulatory disadvantage.

     (b) If (i) any Bank requests compensation under Section 4.1, or if the Borrower is required to
pay any additional amount to any Bank or any Governmental Authority for the account of any Bank
pursuant to Section 4.3, (ii) any Bank becomes a Defaulting Bank or (iii) any Bank refuses to
consent to any proposed amendment, modification, waiver or consent with respect to any provision
hereof that requires the unanimous approval of all Banks, or the approval of each of the Banks
affected thereby (in each case in accordance with Section 10.1), and the consent of the Majority
Banks shall have been obtained with respect to such amendment, modification, waiver or consent,
then the Borrower may, at its sole expense and effort (including payment of any applicable
processing and recordation fees), upon notice to such Bank and the Administrative Agent, require
such Bank to assign and delegate, without recourse (in accordance with and subject to the
restrictions contained in Section 10.6(c)), all its interests, rights and obligations under this
Agreement to an assignee that shall assume such obligations (which assignee may be another Bank, if
a Bank accepts such assignment); provided that (A) the Borrower shall have received (I) the
prior written consent of the Administrative Agent with
respect to any assignee that is not already a Bank hereunder (and if a Commitment is being
assigned, each Issuing Bank), which consent shall not unreasonably be withheld, conditioned or
delayed, (II) the consent of such assignee to the assignment and (III) in the case of clause
(b)(iii) above, the consent of such assignee to the proposed amendment, modification, waiver or
consent, (B) such Bank shall have received payment of all amounts owing to such Bank hereunder and
under any other Loan Document (including any amounts arising under Section 3.7 as a consequence of
such assignment), (C) in the case of any such assignment resulting from a claim for compensation
under Section 4.1 or payments required to be made pursuant to Section 4.3, such assignment will
result in a reduction in such compensation or payments, (D) prior to any such assignment, such Bank
shall have taken no action under Section 4.7(a) so as to eliminate the continued need for payment
of amounts owing pursuant to Section 4.1 or Section 4.3 and (E) until such time as such assignment
shall be consummated, the Borrower shall pay all additional amounts (if any) required pursuant to
Section 4.1 or Section 4.3, as the case may be. A Bank shall not be required to make any such
assignment and delegation if, prior thereto, as a result of a waiver by such Bank or otherwise, the
circumstances entitling the Borrower to require such assignment and delegation cease to apply.

     SECTION 4.8. Determination and Notice of Additional Costs and Other Amounts. (a) In determining
the amount of any claim for reimbursement or compensation under Sections 3.4, 3.7 and 4.1, each
Bank may use any reasonable averaging, attribution and allocation methods consistent with such
methods customarily employed by such Bank in similar situations.

     (b) Each Bank or, with respect to compensation claimed by it pursuant to Section 4.3, the
Administrative Agent, as the case may be, will (i) use its best efforts to notify the Borrower
through the Administrative Agent (in the case of each Bank) of any event occurring after the date
of this Agreement promptly after the occurrence thereof and (ii) notify the Borrower through the
Administrative Agent (in the case of each Bank) promptly after such Bank or the Administrative
Agent, as the case may be, becomes aware of any event occurring after the date of this Agreement,
in either case if such event (for purposes of this Section 4.8(b), a “Triggering Event”)
will entitle such Bank or the Administrative Agent, as the case may be, to compensation

51

 

pursuant to Section 3.4, 3.7, 4.1 or 4.3, as the case may be. Each such notification of a Triggering Event
shall be accompanied by a certificate of such Bank or the Administrative Agent, as the case may be,
setting forth the calculations and justification in reasonable detail such amount or amounts as
shall be necessary to compensate such Bank or the Administrative Agent, as the case may be, as
specified in Section 3.4, 3.7, 4.1 or 4.3, as the case may be, and certifying that such costs are
generally being charged by such Bank to other similarly situated borrowers under similar credit
facilities, which certificate shall be conclusive absent manifest error. The Borrower shall pay to
the Administrative Agent for the account of such Bank or to the Administrative Agent for its own
account, as the case may be, the amount shown as due on any such certificate within ten Business
Days after its receipt of the same.

and warrants as follows:

          (a) Organizational Status of the Borrower. The Borrower (i) is validly organized and
existing as a limited liability company and in good standing under the laws of its
jurisdiction of organization; (ii) is duly authorized or qualified to do business in, and is
in good standing in, each other jurisdiction in which the conduct of its business or the ownership
or leasing of its Property requires it to be so authorized or qualified to do business, except
where the failure to be so duly authorized or qualified or in good standing, individually or in the
aggregate, would not reasonably be expected to have a Material Adverse Effect, and (iii) has the
limited liability company or other requisite power and authority to conduct its business, as
presently conducted.

          (b) Organizational Status of Significant Subsidiaries of the Borrower. Each
Significant Subsidiary of the Borrower (i) is validly organized and existing and in good standing
under the laws of the jurisdiction of its organization and is duly authorized or qualified to do
business in, and is in good standing in, each other jurisdiction in which the conduct of its
business or the ownership or leasing of its Property requires it to be so authorized or qualified
to do business, except where the failure to be so validly organized and existing or duly authorized
or qualified or in good standing, individually or in the aggregate, would not reasonably be
expected to have a Material Adverse Effect and (ii) has the corporate, partnership or other
requisite power and authority to conduct its business, as presently conducted, except where the
failure to have such power and authority, individually or in the aggregate, would not reasonably be
expected to have a Material Adverse Effect.

          (c) Organizational Powers. The Borrower has the limited liability company or other
requisite power to execute, deliver and perform and comply with its obligations under this
Agreement, any Notes and the other Loan Documents to which it is a party. This Agreement and each
other Loan Document to which the Borrower is a party have been duly executed and delivered on
behalf of the Borrower.

          (d) Authorization, No Conflict, Etc. The Borrowings by the Borrower contemplated by
this Agreement, the execution and delivery by the Borrower of this Agreement and the other Loan
Documents to which it is a party and the performance by the Borrower of its obligations hereunder
and thereunder have been duly authorized by all requisite limited liability company or other
requisite action on the part of the Borrower and do not and will not (i) violate any law or any
order of any court or other Governmental Authority to which the Borrower is subject, (ii) violate
the articles of organization or operating agreement or other organizational documents (each as
amended from time to time) of the Borrower, (iii) violate or result in a default under any
indenture, loan agreement or other agreement to which the Borrower or any Restricted Subsidiary of
the Borrower is a party or by which the Borrower or any Restricted Subsidiary of the Borrower, or
any of their respective Property, is bound (except for such violations or defaults that,
individually or in the aggregate, would not reasonably be expected to

55

 

have a Material Adverse
Effect) or (iv) result in or require the creation or imposition of any material Lien upon any of
the Properties of the Borrower or any Significant Subsidiary not permitted under this Agreement.

          (e) Governmental Approvals and Consents. No authorization or approval or action by,
and no notice to or filing with, any Governmental Authority is required for the due execution,
delivery and performance by the Borrower of, or for the Borrowings under, this Agreement and the
other Loan Documents to which it is a party, except (i) those that have been
obtained or made and (ii) such matters relating to performance as would ordinarily be done in
the ordinary course of business after the Closing Date.

          (f) Obligations Binding. This Agreement and the other Loan Documents to which the
Borrower is a party constitute the legal, valid and binding obligations of the Borrower,
enforceable against the Borrower in accordance with their respective terms (assuming due and valid
authorization, execution and delivery of this Agreement and such other Loan Documents by each party
other than the Borrower), except as such enforceability may be (i) limited by the effect of any
applicable bankruptcy, insolvency, reorganization, moratorium or other similar laws relating to or
affecting the enforcement of creditors’ rights generally and (ii) subject to the effect of general
principles of equity (regardless of whether such enforceability is considered in a proceeding in
equity or at law).

          (g) Use of Proceeds, Margin Stock. The proceeds of the Loans will be used by the
Borrower (i) to refinance its obligations under the Existing Facility, (ii) to support commercial
paper issued by the Borrower and (iii) for other general corporate purposes. Neither the Borrower
nor any Restricted Subsidiary of the Borrower is principally engaged in, or has as one of its
important activities, the business of extending credit for the purpose of purchasing or carrying
any Margin Stock, and no part of the proceeds of any Loan made to the Borrower will be used for any
purpose that would violate the provisions of the margin regulations of the Board.

          (h) Title to Properties. The issued and outstanding Capital Stock owned by the
Borrower of each of its Significant Subsidiaries, whether such stock is owned directly or
indirectly through one or more of its Subsidiaries, is owned free and clear of any Lien. In
addition, each of the Borrower and each Significant Subsidiary has good title to, or valid
leasehold interests in, all its real and personal property material to its business, except for
defects in title and exceptions to leasehold interests that either individually or in the aggregate
would not reasonably be expected to result in a Material Adverse Effect, and all such Properties
are free and clear of any Lien except Liens permitted under this Agreement.

          (i) Investment Company Act. Neither the Borrower nor any Restricted Subsidiary of the
Borrower is an “investment company” as defined in, or otherwise subject to regulation under, the
Investment Company Act of 1940, as amended.

          (j) Material Adverse Change. Since December 31, 2010, there has been no event,
development or circumstance that, as of the Closing Date, has had, or would reasonably be expected
to have, a Material Adverse Effect.

56

 

          (k) Litigation. As of the Closing Date, there is no litigation, action, suit,
investigation or other legal or governmental proceeding by or before any arbitrator or Governmental
Authority pending against or, to the best knowledge of the Borrower, threatened against the
Borrower or any of its Subsidiaries, at law or in equity, (i) relating to the transactions under
this Agreement or under any other Loan Document or (ii) as to which there is a reasonable
possibility of an adverse decision that would have a Material Adverse Effect.

          (l) ERISA. There is no event or events, individually or in the aggregate, that could
reasonably be expected to have a Material Adverse Effect, arising out of or in connection
with (i) any Reportable Event or “accumulated funding deficiency” (within the meaning of
Section 412 of the Code or Section 302 of ERISA) with respect to any Plan that has occurred during
the five-year period immediately preceding the date on which this representation is made or deemed
made, (ii) any failure of a Plan to comply with the applicable provisions of ERISA and the Code,
(iii) any termination of a Single Employer Plan, (iv) any complete or partial withdrawal by the
Borrower or any Commonly Controlled Entity from any Multiemployer Plan, (v) any Lien in favor of
the PBGC or any Plan that has arisen during the five-year period referred to in clause (i) above or
(vi) a Multiemployer Plan being in Reorganization or being Insolvent.

          (m) Financial Statements. The consolidated financial statements of the Borrower as of
and for the fiscal quarter ended June 30, 2011 filed with the SEC with the Borrower’s 10-Q for the
period then ended, copies of which have been delivered to the Banks, present fairly in all material
respects the consolidated financial condition and results of operations of the Borrower, its
Consolidated Subsidiaries, the Securitization Subsidiaries and the Unrestricted Subsidiaries as of
such date and for the period then ended, in conformity with, as applicable, GAAP and, except as
otherwise stated therein, consistently applied (in the case of such unaudited statements, subject
to year-end adjustments and the exclusion of detailed footnotes).

          (n) Accuracy of Information. None of the documents or written information (excluding
estimates, financial projections and forecasts) furnished to the Banks by the Borrower in
connection with or pursuant to this Agreement or the other Loan Documents (collectively, the
“Information”), contained, as of the date such Information was furnished (or, if such Information
expressly related to a specific date, as of such specific date), any untrue statement of a material
fact or omitted to state, as of the date such Information was furnished (or, if such Information
expressly related to a specific date, as of such specific date), any material fact (other than
industry-wide risks normally associated with the types of businesses conducted by the Borrower and
its Subsidiaries) necessary to make the statements therein, in the light of the circumstances under
which they were made, not materially misleading, as a whole. The estimates, financial projections
and forecasts furnished to the Banks by the Borrower with respect to the transactions contemplated
under this Agreement were prepared in good faith and on the basis of information and assumptions
that the Borrower believed to be reasonable as of the date such information was prepared (it being
recognized by the Banks that such estimates, financial projections and forecasts as they relate to
future events are not to be viewed as fact and that actual results during the period or periods
covered by such estimates, financial projections and forecasts may differ from the projected
results set forth therein by a material amount).

57

 

          (o) No Violation. The Borrower is not in violation of any order, writ, injunction or
decree of any court or any order, regulation or demand of any Governmental Authority that,
individually or in the aggregate, reasonably could be expected to have a Material Adverse Effect.

          (p) Subsidiaries. Schedule 6.1(p) attached hereto sets forth each Significant
Subsidiary as of the date hereof. Except as disclosed on Schedule 6.1(p), as of the date
hereof the Borrower owns, directly or indirectly through one or more of its Subsidiaries, all of
the outstanding Capital Stock of each Significant Subsidiary, in each case free and clear of any
Liens not permitted under this Agreement.

          (q) Taxes. Each of the Borrower and its Subsidiaries has filed or caused to be filed
all Federal, state and all other material tax returns that are required to be filed by it and has
paid or caused to be paid all taxes shown to be due and payable on said returns or on any
assessments made against it or any of its Property and all other taxes, fees or other charges
imposed on it or any of its Property by any Governmental Authority (other than any such taxes the
amount or validity of which are currently being contested in good faith by appropriate proceedings
and with respect to which reserves in conformity with GAAP have been provided on the books of the
Borrower or its Subsidiaries), except where the failure to do so could not, individually or in the
aggregate, reasonably be expected to have a Material Adverse Effect; no tax Lien has been filed,
and to the knowledge of the Borrower, no claim is being asserted, with respect to any such tax, fee
or other charges (other than any Liens or claims that could not, individually or in the aggregate,
reasonably be expected to have a Material Adverse Effect).

     (vii) promptly after any request therefor, such other information relating to the
Borrower or its business, properties, condition and operations as the Administrative Agent
(or any Bank through the Administrative Agent) may reasonably request.

shall be deemed to have been delivered on the date on which the Borrower provides notice (including
notice by e-mail) to the Administrative Agent (which notice the Administrative Agent will convey

          (b) Use of Proceeds. The Borrower will use the proceeds of the Loans only for
the purposes set forth in Section 6.1(g), and it will not use any Letter of Credit or the proceeds
of any Loan for any purpose that would violate the provisions of the margin regulations of the
Board. The Borrower will not, and will not permit any of its Subsidiaries to, engage principally,
or as one of its important activities, in the business of extending credit for the purpose of
purchasing or carrying, within the meaning of Regulation U, any Margin Stock. Letters of Credit
will be issued only to support the general corporate purposes of the Borrower and its Subsidiaries.

          (c) Existence; Laws. The Borrower will, and will cause each Significant Subsidiary
to, do or cause to be done all things necessary to preserve, renew and keep in full force and
effect its legal existence and all rights, licenses, permits and franchises; provided that
the foregoing shall not prohibit any merger, consolidation, liquidation or dissolution otherwise
permitted under this Agreement; and provided further that neither the Borrower nor
any Significant Subsidiary shall be required to preserve or maintain any rights, licenses, permits
or franchises if the failure to maintain and preserve the same would not reasonably be expected,
individually or in the aggregate, to result in a Material Adverse Effect. The Borrower will, and
will cause each of its Significant Subsidiaries to, comply with all laws and regulations applicable

60

 

to it, except where the failure to do so, individually or in the aggregate, would not reasonably be
expected to have a Material Adverse Effect.

          (d) Maintenance of Properties. The Borrower will, and will cause each Significant
Subsidiary to, preserve and maintain all of its Property that is material to the conduct of the
business of the Borrower and its Subsidiaries, taken as a whole, provided, however,
that nothing in this Section 7.1(d) shall prevent the Borrower or any of its Significant
Subsidiaries from (i) selling, abandoning or otherwise disposing of any Properties (including the
Capital Stock of any Subsidiary of the Borrower that is not a Significant Subsidiary) if (x) the
retention of such Properties in the good faith judgment of the Borrower or such Significant
Subsidiary is
inadvisable or unnecessary to the business of the Borrower and its Subsidiaries, taken as a
whole, or (y) the failure to preserve and maintain such Properties would not reasonably be expected
to have a Material Adverse Effect or (ii) engaging in any other transaction that is expressly
permitted by the terms of any other provision of this Agreement.

          (e) Maintenance of Business Line. The Borrower will maintain its fundamental business
of providing services and products in the energy market.

          (f) Books and Records; Access. The Borrower will, and will cause each Significant
Subsidiary to, keep proper books of record and account in which complete and accurate entries, in
all material respects, are made of its financial and business transactions to the extent required
by GAAP. The Borrower will, and will cause each of its Significant Subsidiaries to, at any
reasonable time and from time to time, permit up to six representatives of the Banks designated by
the Majority Banks, or representatives of the Administrative Agent, on not less than five Business
Days’ notice, to examine and make copies of and abstracts from the records and books of account of,
and visit the properties of, the Borrower and each Significant Subsidiary and to discuss the
general business affairs of the Borrower and each of its Significant Subsidiaries with their
respective officers and independent certified public accountants (provided that, so long as
no Default or Event of Default shall have occurred and be continuing, the Borrower shall have the
opportunity to be present at any such discussion with such independent certified public
accountants); subject, however, in all cases to the imposition of such conditions as the Borrower
and each of its Significant Subsidiaries shall deem necessary based on reasonable considerations of
safety and security; provided, however, that neither the Borrower nor any of its
Significant Subsidiaries shall be required to disclose to any Agent, any Bank or any agents or
representatives thereof any information which is the subject of attorney-client privilege or
attorney work-product privilege properly asserted by the applicable Person to prevent the loss of
such privilege in connection with such information or which is prevented from disclosure pursuant
to a confidentiality agreement with third parties. Notwithstanding the foregoing, none of the
conditions precedent to the exercise of the right of access described in the preceding sentence
that relate to notice requirements or limitations on the Persons permitted to exercise such right
shall apply at any time when a Default or an Event of Default shall have occurred and be
continuing.

          (g) Insurance. The Borrower will, and will cause each Significant Subsidiary to,
maintain insurance with responsible and reputable insurance companies or associations, or to the
extent that the Borrower or such Significant Subsidiary deems it prudent to do so, through its own
program of self-insurance, in such amounts and covering such risks as is usually carried by

61

 

companies engaged in similar businesses, of comparable size and financial strength and with
comparable risks.

          (h) Credit Rating. The Borrower will deliver to the Administrative Agent notice of
any change by a Rating Agency in the Designated Rating assigned by such Rating Agency promptly upon
the effectiveness of such change.

     SECTION 7.2. Negative Covenants. The Borrower covenants that, so long as any amount
is owing to the Banks hereunder or under any other Loan Document to which it is a party (other than
indemnities and other contingent obligations not then due and payable and as to which no claim has
been made) or any Letter of Credit is outstanding under this Agreement or any Bank shall have any
Commitment outstanding under this Agreement:

          (a) Financial Covenant. The Borrower will not permit, as of the last day of any
fiscal quarter, the ratio of Consolidated Indebtedness for Borrowed Money as of such date to
Consolidated Capitalization as of such date to exceed 65%.

Subsidiaries to, pledge, mortgage, hypothecate or grant a Lien upon, or permit any mortgage,
pledge, security interest or other Lien upon, any Property of the Borrower or any Significant
Subsidiary of the Borrower; provided, however, that this restriction shall neither
apply to nor prevent the creation or existence of:

     (i) Permitted Liens;

     (ii) any Lien in existence on the date hereof; provided that (A) no such Lien
described in this clause (ii) encumbers any additional Property after the date hereof (other
than repairs, renewals, replacements, additions, accessions, improvements and betterments to
the Property originally subject to such Lien) and (ii) the principal amount of Indebtedness
of the Borrower and its Subsidiaries secured thereby is not increased after the date hereof
(except that, if such Indebtedness is refinanced, refunded, renewed or extended after the
Closing Date, the principal amount thereof may be increased by an amount necessary to pay
all accrued and unpaid interest on such Indebtedness being refinanced, refunded, renewed or
extended and any fees and expenses, including premiums, related to such refinancing,
refunding, renewal or replacement);

     (iii) Liens securing bonds issued after the date hereof pursuant to the Original
Mortgage (to the extent the proceeds thereof are used to replace, refund or refinance first
mortgage bonds outstanding on the date hereof) or the General Mortgage Indenture (or second
or subordinated, as the case may be, Liens in lieu thereof);

     (iv) Liens required to be granted pursuant to “equal and ratable” clauses existing on
the date hereof under Contractual Obligations of the Borrower and its Significant

62

 

     (v) Liens on fixed or capital assets and related inventory and intangible assets
acquired, constructed, improved, altered or repaired by the Borrower or any Significant
Subsidiary; provided that (i) such Liens secure Indebtedness otherwise permitted by
this Agreement, (ii) such Liens and the Indebtedness secured thereby are incurred prior to
or within 365 days after such acquisition or the later of the completion of such
construction, improvement, alteration or repair or the date of commercial operation of the
assets constructed, improved, altered or repaired, (iii) the Indebtedness secured thereby
does not exceed the cost of acquiring, constructing, improving, altering or repairing such
fixed or capital assets, as the case may be, and (iv) such Lien shall not apply to any other
property or assets of the Borrower or of its Significant Subsidiaries (other than repairs,
renewals, replacements, additions, accessions, improvements and betterments thereto);

     (vi) Liens on Property and repairs, renewals, replacements, additions, accessions,
improvements and betterments thereto existing at the time such Property is acquired by the
Borrower or any Significant Subsidiary and not created in contemplation of such acquisition

Liens on the Property of any Person at the time such Person becomes a Significant Subsidiary
of the Borrower and not created in contemplation of such Person becoming a Significant
Subsidiary of the Borrower (or on repairs, renewals, replacements, additions, accessions and

     (vii) rights reserved to or vested in any Governmental Authority by the terms of any
right, power, franchise, grant, license or permit, or by any Requirements of Law, to
terminate such right, power, franchise, grant, license or permit or to purchase, condemn,
expropriate or recapture or to designate a purchaser of any of the Property of the Borrower

extension, renewal or refunding of any such Lien shall increase the principal amount of any
Indebtedness secured thereby immediately prior to such extension, renewal or refunding,
unless such Indebtedness is permitted under Section 7.2(a);

     (xii) Liens on cash collateral to secure obligations of the Borrower and its
Significant Subsidiaries in respect of cash management arrangements with any Bank or
Affiliate thereof; and

     (xiii) Liens not otherwise permitted by this Section 7.2(b) securing Indebtedness and
other obligations of the Borrower and its Significant Subsidiaries so long as the

63

 

aggregate
outstanding principal amount of the Indebtedness and obligations secured thereby does not at
any time exceed at the time of incurrence of such Indebtedness or obligations (including any
such incurrence resulting from any extension, renewal or refunding of such Indebtedness or
obligations), as to the Borrower and all of its Significant Subsidiaries, 12.5% of Net
Tangible Assets.

transfer, lease or otherwise dispose of all or substantially all of its Properties to the Borrower,
to another Wholly-Owned Restricted Subsidiary or to a Person that becomes a Wholly-Owned Restricted

Borrower and any Significant Subsidiary may transfer assets in connection with the issuance of
Securitization Securities; provided that (x) in each case, immediately before and after
giving effect to any such merger or consolidation, dissolution or liquidation, or sale, transfer,

effect to any such sale, assignment, transfer or other disposition described in the

64

 

foregoing
clauses (x) and (y), no Default or Event of Default shall have occurred and be continuing.

          (f) Agreements Restricting Dividends. The Borrower will not, and will not permit any
Significant Subsidiary to, enter into, incur or permit to exist any agreement or other consensual
arrangement that explicitly prohibits or restricts the payment by any Significant Subsidiary of
dividends or other distributions with respect to any shares of its Capital Stock; provided
that the foregoing shall not prohibit financial incurrence, maintenance and similar

pursuant to an agreement that has been entered into in connection with a disposition of all or

thereof to cause, (A) such
Indebtedness to become due prior to its stated maturity (other than in
respect of mandatory prepayments required thereby) or (B) in the case of any Guarantee of
Indebtedness for Borrowed Money or Junior Subordinated Debt by the Borrower or any of its

within or beyond the control of any party to this Agreement):

     (a) either of the Events of Default specified in Section 8.1(g) or 8.1(h) occurs with respect

     (i) the Commitments shall immediately be cancelled; and

beneficiaries of the then outstanding Letters of Credit shall have presented the documents
required for draws thereunder), all unpaid accrued interest or fees and any other sum
payable under this Agreement or any other Loan Document shall become immediately due and
payable; or

     (b) any other Event of Default specified in Section 8.1 occurs, then, at any time thereafter

the Majority Banks, by notice to the Borrower, declare that:

     (i) the Commitments shall immediately be cancelled; and/or

     (ii) either (A) all Loans made hereunder, all amounts of L/C Obligations (whether or
not the beneficiaries of the then outstanding Letters of Credit shall have presented the
documents required for draws thereunder), all unpaid accrued interest or
fees and any other sum payable under this Agreement or any other Loan Document shall
become immediately due and payable or (B) all Loans made hereunder, all amounts of

68

 

L/C
Obligations (whether or not the beneficiaries of the then outstanding Letters of Credit
shall have presented the documents required for draws thereunder), all unpaid accrued
interest or fees and any other sum payable under this Agreement or any other Loan Document
shall become due and payable at any time thereafter immediately on demand by the
Administrative Agent (acting on the instructions of the Majority Banks).

          With respect to all Letters of Credit with respect to which presentment for honor shall not
have occurred at the time of an acceleration pursuant to the preceding paragraph or on the
Termination Date, the Borrower shall at such time deposit in a cash collateral account opened by
the Administrative Agent cash or cash equivalents in an amount equal to the aggregate then undrawn
and unexpired face amount of such Letters of Credit. The Borrower hereby grants to the
Administrative Agent, for the benefit of the applicable Issuing Bank and the L/C Participants, a
security interest in such cash collateral to secure all obligations of the Borrower under this
Agreement and the other Loan Documents. Interest shall accrue on amounts deposited in such account
for the benefit of the Borrower at a rate equal to the Federal Funds Effective Rate. Amounts held
in such cash collateral account shall be applied by the Administrative Agent to the payment of
drafts drawn under such Letters of Credit, and the unused portion thereof after all such Letters of
Credit shall have expired or been fully drawn upon, if any, shall be applied to repay other
obligations of the Borrower hereunder and under the Notes. After all such Letters of Credit shall
have expired or been fully drawn upon, all Reimbursement Obligations shall have been satisfied and
all other obligations of the Borrower hereunder and under the Notes shall have been paid in full,
the balance, if any, in such cash collateral account shall be returned to the Borrower. The
Borrower shall execute and deliver to the Administrative Agent, for the account of each Issuing
Bank and the L/C Participants, such further documents and instruments as the Administrative Agent
may reasonably request to evidence the creation and perfection of the within security interest in
such cash collateral account.

Except as expressly provided above in this Section 8.2, presentment, demand, protest, notice of
intent to accelerate, notice of acceleration and all other notices of any kind whatsoever are
hereby expressly waived by the Borrower.

ARTICLE IX

THE ADMINISTRATIVE AGENT

          SECTION 9.1. Appointment. Each Bank hereby irrevocably designates and appoints
JPMorgan Chase Bank, N.A. as the Administrative Agent of such Bank under this Agreement and the
other Loan Documents, and each such Bank irrevocably authorizes JPMorgan Chase Bank, N.A., as the
Administrative Agent for such Bank, to take such action on its behalf under the provisions of this
Agreement and the other Loan Documents and to exercise such powers and perform such duties as are
expressly delegated to the Administrative Agent by the terms of this Agreement and the other Loan
Documents, together with such other powers as are reasonably incidental thereto. Notwithstanding
any provision to the contrary elsewhere in this Agreement, (a) the
Administrative Agent shall not have any duties or responsibilities, except those expressly set
forth herein, or any fiduciary relationship with any Bank, and no implied covenants, functions,
responsibilities, duties, obligations or liabilities shall be read into this Agreement or any other
Loan Document or otherwise exist against the Administrative Agent and (b) the other

69

 

Agents and the
Lead Arrangers shall not have any duties or responsibilities hereunder, or any fiduciary
relationship with any Bank, and no implied covenants, functions, responsibilities, duties,
obligations or liabilities shall be read into this Agreement or any other Loan Document or
otherwise exist against the other Agents or the Lead Arrangers.

     SECTION 9.2. Delegation of Duties. The Administrative Agent may execute any of its
duties under this Agreement and the other Loan Documents by or through agents or attorneys-in-fact
and shall be entitled to advice of counsel concerning all matters pertaining to such duties. The
Administrative Agent shall not be responsible for the negligence or misconduct of any agents or
attorneys-in-fact selected by it with reasonable care.

     SECTION 9.3. Exculpatory ProvisionsNeither any Agent nor any of their respective
officers, directors, employees, agents, advisors, attorneys-in-fact or Affiliates shall be (a)
liable for any action lawfully taken or omitted to be taken by it or such Person under or in
connection with this Agreement or any other Loan Document (except to the extent that any of the
foregoing are found by a final and non-appealable decision of a court of competent jurisdiction to
have resulted from its or such Person’s own gross negligence or willful misconduct) or (b)
responsible in any manner to any of the Banks for any recitals, statements, representations or
warranties made by the Borrower or any officer thereof contained in this Agreement or any other
Loan Document or in any certificate, report, statement or other document referred to or provided
for in, or received by the Administrative Agent or any other Agent under or in connection with,
this Agreement or any other Loan Document or for the value, validity, effectiveness, genuineness,
enforceability or sufficiency of this Agreement or any Note or any other Loan Document or for any
failure of the Borrower to perform its obligations hereunder or thereunder. The Agents shall not be
under any obligation to any Bank to ascertain or to inquire as to the observance or performance of
any of the agreements contained in, or conditions of, this Agreement or any other Loan Document, or
to inspect the properties, books or records of the Borrower.

     SECTION 9.4. Reliance by Administrative Agent. The Administrative Agent shall be
entitled to rely, and shall be fully protected in relying, upon any instrument, note, writing,
resolution, notice, consent, certificate, affidavit, letter, facsimile, email, statement, order or
other document or conversation believed by it to be genuine and correct and to have been signed,
sent or made by the proper Person or Persons and upon advice and statements of legal counsel
(including counsel to the Borrower), independent accountants and other experts selected by the
Administrative Agent. The Administrative Agent may deem and treat the payee of any Note or any loan
account in the Register as the owner thereof for all purposes unless a written notice of
assignment, negotiation or transfer thereof shall have been filed with the Administrative Agent.
The Administrative Agent shall be fully justified
in failing or refusing to take any action under this Agreement or any other Loan Document
unless it shall first receive such advice or concurrence of the Majority Banks (or, if so specified
by this Agreement, all Banks) as it deems appropriate or it shall first be indemnified to its
satisfaction by the Banks against any and all liability and expense that may be incurred by it by
reason of taking or continuing to take any such action. The Administrative Agent shall in all cases
be fully protected in acting, or in refraining from acting, under this Agreement and the other Loan
Documents in accordance with a request of the Majority Banks (or, if so specified by this
Agreement, all Banks), and such request and any action taken or failure to act pursuant thereto
shall be binding upon all the Banks and all future holders of the amounts owing hereunder.

70

 

     SECTION 9.5. Notice of Default. The Administrative Agent shall not be deemed to have
knowledge or notice of the occurrence of any Default or Event of Default hereunder unless the
Administrative Agent has received notice from a Bank or the Borrower referring to this Agreement,
describing such Default or Event of Default and stating that such notice is a “notice of default”.
In the event that the Administrative Agent receives such a notice, the Administrative Agent shall
give notice thereof to the Banks. The Administrative Agent shall take such action with respect to
such Default or Event of Default as shall be reasonably directed by the Majority Banks (or, if so
specified by this Agreement, all Banks); provided that unless and until the Administrative
Agent shall have received such directions, the Administrative Agent may (but shall not be obligated
to) take such action, or refrain from taking such action, with respect to such Default or Event of
Default as it shall deem advisable in the best interests of the Banks.

     SECTION 9.6. Non-Reliance on Administrative Agent, Lead Arrangers and Other Banks.
Each Bank expressly acknowledges that neither the Agents and the Lead Arrangers nor any of their
respective officers, directors, employees, agents, advisors, attorneys-in-fact or Affiliates have
made any representations or warranties to it and that no act by any Agent or any Lead Arranger
hereafter taken, including any review of the affairs of the Borrower, shall be deemed to constitute
any representation or warranty by any Agent or any Lead Arranger, as applicable, to any Bank. Each
Bank represents to the Agents and the Lead Arrangers that it has, independently and without
reliance upon any Agent, any Lead Arranger or any other Bank, and based on such documents and
information as it has deemed appropriate, made its own appraisal of and investigation into the
business, operations, property, financial and other condition and creditworthiness of the Borrower
and made its own decision to make its Loans hereunder and enter into this Agreement. Each Bank also
represents that it will, independently and without reliance upon any Agent, any Lead Arranger or
any other Bank, and based on such documents and information as it shall deem appropriate at the
time, continue to make its own credit analysis, appraisals and decisions in taking or not taking
action under this Agreement and the other Loan Documents, and to make such investigation as it
deems necessary to inform itself as to the business, operations, property, financial and other
condition and creditworthiness of the Borrower. Except for notices, reports and other documents
expressly required to be furnished to the Banks by the Administrative Agent hereunder, the
Administrative Agent shall not have any duty or responsibility to provide any Bank with any credit
or other information concerning the
business, operations, property, condition (financial or otherwise), prospects or
creditworthiness of the Borrower that may come into the possession of the Administrative Agent or
any of its officers, directors, employees, agents, advisors, attorneys-in-fact or Affiliates.

     SECTION 9.7. Indemnification. The Banks agree to indemnify each Agent, each Lead
Arranger and their respective officers, directors, employees, partners, affiliates, agents,
advisors and controlling persons (each, an “Agent Indemnitee”) (to the extent not
reimbursed by the Borrower and without limiting the obligation of the Borrower to do so), ratably
according to their respective applicable Revolving Percentages in effect on the date on which
indemnification is sought under this Section 9.7 (or, if indemnification is sought after the date
upon which the Commitments shall have terminated and the Loans shall have been paid in full,
ratably in accordance with such applicable Revolving Percentages immediately prior to such date),
from and against any and all liabilities, obligations, losses, damages, penalties, actions,
judgments, suits, costs, expenses or disbursements of any kind whatsoever that may at any time
(including at any time following the payment of all amounts owing hereunder and the termination of
the

71

 

Commitments) be imposed on, incurred by or asserted against such Agent Indemnitee in any way
relating to or arising out of, the Commitments, this Agreement, any of the other Loan Documents or
any documents contemplated by or referred to herein or therein or the transactions contemplated
hereby or thereby or any action taken or omitted by such Agent Indemnitee under or in connection
with any of the foregoing; provided that no Bank shall be liable for the payment of any
portion of such liabilities, obligations, losses, damages, penalties, actions, judgments, suits,
costs, expenses or disbursements that are found to by a final and non-appealable decision of a
court of competent jurisdiction to have resulted from such Agent Indemnitee’s gross negligence or
willful misconduct. The agreements in this Section 9.7 shall survive the termination of this
Agreement and the payment of the Loans and all other amounts payable hereunder.

     SECTION 9.8. Agent in Its Individual Capacity. Each Agent and its Affiliates may make
loans to, accept deposits from and generally engage in any kind of business with the Borrower as
though such Agent were not an Agent hereunder and under the other Loan Documents. With respect to
its Loans made or renewed by it, any Letter of Credit issued or participated in by it and its
Commitment hereunder, each Agent shall have the same rights and powers under this Agreement and the
other Loan Documents as any Bank and may exercise the same as though it were not an Agent, and the
terms “Bank” and “Banks” shall include the each Agent in its individual capacity.

     SECTION 9.9. Successor Administrative Agent. The Administrative Agent may resign as
Administrative Agent upon 10 days’ notice to the Banks and the Borrower. If the Administrative
Agent shall resign as Administrative Agent under this Agreement and the other Loan Documents, then
the Majority Banks shall appoint from among the Banks a successor agent for the Banks, which
successor agent shall (unless an Event of Default under Sections 8.1(a), (g) or (h) with respect to
the Borrower shall have occurred and be continuing) be subject to approval by the Borrower (which
approval shall not be unreasonably withheld or delayed), whereupon such successor agent shall
succeed to the
rights, powers and duties of the Administrative Agent, and the term “Administrative Agent”
shall mean such successor agent effective upon such appointment and approval, and the former
Administrative Agent’s rights, powers and duties as Administrative Agent shall be terminated,
without any other or further act or deed on the part of such former Administrative Agent or any of
the parties to this Agreement or any holders of any amounts payable hereunder. If a successor
Administrative Agent shall not have been so appointed within 15 days after the resigning
Administrative Agent gives notice of its resignation, the resigning Administrative Agent may then
appoint a successor Administrative Agent who shall be a financial institution engaged or licensed
to conduct banking business under the laws of the United States with an office in the United States
and that has total assets in excess of $500,000,000 and who shall serve as Administrative Agent
until such time, if any, as an Administrative Agent shall have been appointed by the Majority Banks
(with the consent of the Borrower to the extent required above) as provided above. After any
Administrative Agent’s resignation as Administrative Agent, the provisions of this Article IX and
of Section 10.5 shall continue to inure to its benefit as to any actions taken or omitted to be
taken by it while it was Administrative Agent under this Agreement and the other Loan Documents.

     SECTION 9.10. Co-Syndication Agents, Co-Documentation Agents, Lead Arrangers and Global
Coordinators. Notwithstanding anything to the contrary contained herein, no Bank

72

 

identified as
a “Co-Syndication Agent”, “Co-Documentation Agent”, “Lead Arranger” or “Global Coordinator” shall
have the right, power, obligation, liability, responsibility or duty under this Agreement or any
other Loan Document other than those applicable to all Banks as such. Without limiting the
foregoing, none of the Banks so identified shall have or be deemed to have any fiduciary
relationship with any Bank. Each Bank acknowledges that it has not relied, and will not rely, on
any of the Banks so identified in deciding to enter into this Agreement or not taking action
hereunder.

ARTICLE X

     (b) The Borrower hereby acknowledges that (i) certain of the Lenders may be “public-side”
Lenders (i.e., Lenders that do not wish to receive material non-public information with respect to
the Borrower or its securities) (each, a “Public Lender”) and (ii) the Administrative Agent
will make available to the Lenders certain notices, requests, financial statements, financial and
other reports, certificates and other information materials, but excluding any such communication
that initiates or responds to the legal process (all such non-excluded information being referred
to herein collectively as the “Communications”) on IntraLinks or
another relevant website (whether a commercial, third-party website or whether sponsored by
the Administrative Agent) (the “Platform”). The Borrower hereby agrees that all
Communications that are to be made available to Public Lenders shall be clearly and conspicuously
marked “PUBLIC” which, at a minimum, shall mean that the word “PUBLIC” shall appear prominently on
the first page thereof, (ii) by marking Communications “PUBLIC,” the Borrower shall be deemed to
have authorized the Administrative Agent, the Issuing Banks and the Lenders to treat such
Communications as not containing any material non-public information with respect to the Borrower
or its securities for purposes of United States Federal and state securities laws, it being
understood that certain of such Communications may be subject to the confidentiality requirements
hereof, (iii) all Communications marked “PUBLIC” are permitted to be made available through a
portion of the Platform designated “Public Investor,” and (iv) the Administrative Agent shall be
entitled to treat any Communications that are not marked “PUBLIC” as being suitable only for
posting on a portion of the Platform not designated “Public Investor.” Notwithstanding the
foregoing, (A) the Borrower shall be under no obligation to mark any Communications “PUBLIC,” and
each Public Lender hereby waives its right to receive any Communications that are not marked
“PUBLIC”; and (B) the Administrative Agent shall treat Communications that are deemed to have been
delivered based on notice pursuant to the last sentence of Section 7.1(a) as “PUBLIC.”

     (c) The Administrative Agent or the Borrower may, in its discretion, agree to accept notices
and other communications pursuant to procedures approved by it; provided that approval of
such procedures may be limited to particular notices or circumstances.

75

 

     (d) Any party hereto may change its address, facsimile number or electronic mail address for
notices and other communications hereunder by notice to the other parties hereto.

     SECTION 10.3. No Waiver; Cumulative Remedies. No failure to exercise and no delay in
exercising, on the part of the Administrative Agent or any Bank, any right, remedy, power or
privilege hereunder shall operate as a waiver thereof, nor shall any single or partial exercise of
any right, remedy, power or privilege hereunder preclude any other or further exercise thereof or
the exercise of any other right, remedy, power or privilege. The rights, remedies, powers and
privileges herein provided are cumulative and not exclusive of any rights, remedies, powers and
privileges provided by law.

     SECTION 10.4. Survival of Representations and Warranties. All representations and
warranties made hereunder and in any document, certificate or statement delivered pursuant hereto
or in connection herewith shall survive the execution and delivery of this Agreement.

     SECTION 10.5. Payment of Expenses; Indemnity. (a) The Borrower agrees (i) to pay all
reasonable out-of-pocket expenses of the Global Coordinators associated with the syndication of the
Facility, (ii) to pay or reimburse the Administrative Agent for all its reasonable out-of-pocket
costs and expenses incurred in connection with the preparation, negotiation and execution and
delivery of, and any amendment, supplement or modification to, this Agreement and the other Loan
Documents and any other
documents prepared in connection herewith or therewith, and the consummation and
administration of the transactions contemplated hereby and thereby, including the reasonable fees
and disbursements of Simpson Thacher & Bartlett LLP, counsel to the Administrative Agent (but
excluding the fees or expenses of any other counsel), (iii) to pay or reimburse the Administrative
Agent for all its costs and expenses incurred in connection with the enforcement or preservation of
its rights under this Agreement, the other Loan Documents and any other documents prepared in
connection herewith or therewith, including the reasonable fees and disbursements of the special
counsel to the Administrative Agent, (iv) to pay or reimburse each Bank for all its costs and
expenses incurred in connection with the enforcement, or at any time after the occurrence and
during the continuance of a Default or an Event of Default, the preservation, of its rights under
this Agreement, the other Loan Documents and any other documents prepared in connection herewith or
therewith, including (A) the reasonable fees and disbursements of counsel to such Bank and (B)
other out-of-pocket expenses incurred during any workout, restructuring or negotiations in respect
of such Loans or Letters of Credit, (v) without duplication of any other provision contained in
this Agreement or any Notes, to pay, indemnify, and hold each Bank and the Administrative Agent
harmless from, any and all recording and filing fees (for which each Bank has not been otherwise
reimbursed by the Borrower under this Agreement), if any, that may be payable or determined to be
payable in connection with the execution and delivery of, or consummation or administration of any
of the transactions contemplated by, or any amendment, supplement or modification of, or any waiver
or consent under or in respect of, this Agreement, the other Loan Documents and any other documents
prepared in connection herewith or therewith, and (vi) without duplication of any other provision
contained in this Agreement or any Notes, to pay, indemnify and hold the Administrative Agent, each
Global Coordinator, each Lead Arranger, each Bank, each Issuing Bank, each Swingline Lender and
each Agent together with their respective directors, officers, employees, agents, trustees,
advisors and Affiliates (collectively, the “Indemnified Persons”), harmless from and
against, any and all losses, claims, damages and liabilities (and shall

76

 

reimburse each Indemnified
Person upon demand for any reasonable legal or other expenses incurred by such Indemnified Person
in connection with investigating or defending any of the foregoing), incurred by any Indemnified
Person arising out of, in connection with, or as a result of the execution, delivery, enforcement,
performance and administration of this Agreement and the other Loan Documents, the transactions
contemplated by this Agreement and the other Loan Documents, or the use, or proposed use, of
proceeds of the Loans (all the foregoing in this clause (vi), collectively, the “Indemnified
Liabilities”); provided that the Borrower shall have no obligation hereunder to an
Indemnified Person with respect to Indemnified Liabilities arising from or in connection with (A)
the gross negligence or willful misconduct of such Indemnified Person or (B) the material breach by
such Indemnified Person of the express terms of this Agreement, in the case of each of the
foregoing clauses (A) and (B) as determined by a final, non-appealable judgment of a court of
competent jurisdiction, AND PROVIDED FURTHER THAT, SUBJECT TO THE LIMITATIONS DESCRIBED HEREIN, IT
IS THE INTENTION OF THE BORROWER TO INDEMNIFY THE INDEMNIFIED PERSONS AGAINST THE CONSEQUENCES OF
THEIR OWN NEGLIGENCE.

     (b) Each party hereto hereby waives, to the maximum extent permitted by applicable law, any
right it may have to claim or recover from any other party hereto any special, indirect, punitive
or consequential damages (as opposed to direct or actual damages) arising out of, in connection
with, or as a result of the execution, delivery, enforcement, performance and
administration of this Agreement and the other Loan Documents, the transactions contemplated
by this Agreement and the other Loan Documents, or the use, or proposed use, of proceeds of the
Loans; provided that nothing contained in this paragraph (b) shall limit the Borrower’s
indemnification provisions contained in paragraph (a) above.

     (c) In the case of an investigation, litigation or other proceeding to which the indemnity in
this Section 10.5 applies, such indemnity shall be effective whether or not such investigation,
litigation or proceeding is brought by the Borrower, any of the Borrower’s directors, security
holders, affiliates, creditors, an Indemnified Person or any other Person, whether or not an
Indemnified Person is otherwise a party to this Agreement.

     (d) The agreements in this Section 10.5 shall survive repayment of the Loans and all other
amounts payable hereunder and termination of this Agreement.

     SECTION 10.6. Effectiveness, Successors and Assigns; Participations; Assignments. (a)
This Agreement shall become effective on the date hereof and thereafter shall be binding upon and
inure to the benefit of the Borrower, the Banks, each Issuing Bank, the Administrative Agent, all
future holders of the Loans and their respective successors and assigns, except that the Borrower
may not assign or transfer any of its rights or obligations under this Agreement without the prior
written consent of each Bank.

     (b) Any Bank may, without the consent of the Borrower or the Administrative Agent, in the
ordinary course of its business and in accordance with applicable law, at any time sell to one or
more banks or other financial institutions or Bank Affiliates (a “Participant”)
participating interests in any Loan owing to such Bank, any Note held by such Bank, any Commitment
of such Bank or any other interest of such Bank hereunder and under the other Loan Documents. In
the event of any such sale by a Bank of a participating interest to a Participant, such Bank’s

77

 

obligations under this Agreement to the other parties to this Agreement shall remain unchanged,
such Bank shall remain solely responsible for the performance thereof, such Bank shall remain the
holder of any such Loan and Commitment or other interest for all purposes under this Agreement and
the other Loan Documents, the Borrower and the Administrative Agent shall continue to deal solely
and directly with such Bank in connection with such Bank’s rights and obligations under this
Agreement and the other Loan Documents and, except with respect to the matters set forth in Section
10.1, the amendment of which requires the consent of all of the Banks, the participation agreement
between the selling Bank and the Participant may not restrict such Bank’s voting rights hereunder.
The Borrower agrees that each Participant shall be entitled to the benefits of Sections 4.1 and 4.3
(subject to the requirements and limitations therein, including the requirements under Section
4.3(e) and Section 4.3(f) (it being understood that the documentation required under Section 4.3(e)
and Section 4.3(f) shall be delivered to the participating Bank)) to the same extent as if it were
a Bank and had acquired its interest by assignment pursuant to paragraph (c) of this Section;
provided that such Participant (i) agrees to be subject to the provisions of Sections 4.1
and 4.3 as if it were an assignee under paragraph (c) of this Section and (ii) shall not be
entitled to receive any greater payment under Sections 4.1 or 4.3, with respect to any
participation, than its participating Bank would have been entitled to receive, except to the
extent such entitlement to receive a greater payment results from an adoption of or any change in
any Requirement of Law or in the interpretation or application
thereof or compliance by any Bank with any request or directive (whether or not having the
force of law) from any central bank or other Governmental Authority made subsequent to the date
hereof that occurs after the Participant acquired the applicable participation. The Borrower
further agrees that each Participant, to the extent provided in its participation, shall be
entitled to the benefits of Sections 3.4 and 3.7 with respect to its participation in the
Commitments and the Loans outstanding from time to time; provided that (i) no Participant
shall be entitled to receive any greater amount pursuant to such Sections than the selling Bank
would have been entitled to receive in respect of the amount of the participation sold by such
selling Bank to such Participant had no such sale occurred and (ii) each such sale of participating
interests shall be to a “qualified purchaser”, as such term is defined under the Investment Company
Act of 1940, as amended. Except as expressly provided in this Section 10.6(b), no Participant
shall be a third-party beneficiary of or have any rights under this Agreement or under any of the
other Loan Documents. Each Bank that sells a participation, acting solely for this purpose as an
agent of the Borrower, shall maintain a register on which it enters the name and address of each
Participant and the principal amounts (and stated interest) of each Participant’s interest in the
Loans or other obligations under this Agreement (the “Participant Register”);
provided that no Bank shall have any obligation to disclose all or any portion of the
Participant Register to any Person (including the identity of any Participant or any information
relating to a Participant’s interest in any Commitments, Loans, Letters of Credit or its other
obligations under any Loan Document) except to the extent that such disclosure is necessary to
establish that such Commitment, Loan, Letter of Credit or other obligation is in registered form
under Section 5f.103-1(c) of the United States Treasury Regulations. The entries in the Participant
Register shall be conclusive, and such Bank, each of the Borrower or any of its Subsidiaries that
is a party to any Loan Document, and the Administrative Agent shall treat each person whose name is
recorded in the Participant Register pursuant to the terms hereof as the owner of such
participation for all purposes of this Agreement, notwithstanding notice to the contrary.

78

 

     (c) Except as set forth below, the Banks shall be permitted to assign all or a portion of
their Loans and Commitments to one or more financial institutions (“Purchasing Banks”) with
the consent, not to be unreasonably withheld, of (a) the Borrower (provided that the Borrower shall
be deemed to have consented to such assignment unless it shall have notified the Administrative
Agent of its refusal to give such consent within 10 Business Days following the Borrower’s receipt
from the transferor Bank of a fully-completed Assignment and Acceptance (as defined below) with
respect to such assignment, delivered in accordance with Section 10.2), unless (i) the Purchasing
Bank is a Bank or a Bank Affiliate or (ii) an Event of Default has occurred and is continuing, (b)
the Administrative Agent, unless the assignment is from a Bank to its Bank Affiliate, and (c) each
Issuing Bank, unless the assignment is from a Bank to its Bank Affiliate, pursuant to an Assignment
and Acceptance, substantially in the form of Exhibit C (an “Assignment and
Acceptance”), executed by such Purchasing Bank and such transferor Bank (and by the Borrower,
the Administrative Agent and each Issuing Bank, as applicable) and delivered to the Administrative
Agent for its acceptance and recording in the Register; provided that (i) such Purchasing
Bank is a “qualified purchaser” as defined under the Investment Company Act of 1940, as amended,
(ii) each such sale shall be of a uniform, and not a varying, percentage of all rights and
obligations under and in respect of the Commitment of such Bank, (iii) each such sale shall be in
an aggregate amount of not less than $5,000,000 (or such lesser amount representing the entire
Commitment of such transferor Bank) if such sale is not to an existing Bank and (iv) after giving
effect to such sale, the transferor Bank shall (to the extent that
it continues to have any Commitment hereunder) have a Commitment of not less than $5,000,000,
provided that such amounts shall be aggregated in respect of each Bank and its Bank
Affiliates, if any. Upon such execution, delivery, acceptance and recording, from and after the
effective date determined pursuant to such Assignment and Acceptance (the “Transfer Effective
Date”), (i) the Purchasing Bank thereunder shall be a party hereto and, to the extent provided
in such Assignment and Acceptance, have the rights and obligations of a Bank hereunder with the
Commitments as set forth therein and (ii) the transferor Bank thereunder shall, to the extent
provided in such Assignment and Acceptance, be released from its obligations under this Agreement
(and, in the case of an Assignment and Acceptance covering all or the remaining portion of a
transferor Bank’s rights and obligations under this Agreement, such transferor Bank shall cease to
be a party hereto). Such Assignment and Acceptance shall be deemed to amend this Agreement to the
extent, and only to the extent, necessary to reflect the addition of such Purchasing Bank and the
resulting adjustment of Revolving Percentages arising from the purchase by such Purchasing Bank of
all or a portion of the rights and obligations of such transferor Bank under this Agreement. On or
prior to the Transfer Effective Date determined pursuant to such Assignment and Acceptance, (i)
appropriate entries shall be made in the accounts of the transferor Bank and the Register
evidencing such assignment and releasing the Borrower from any and all obligations to the
transferor Bank in respect of the assigned Loan or Loans and (ii) appropriate entries evidencing
the assigned Loan or Loans shall be made in the accounts of the Purchasing Bank and the Register as
required by Section 3.1 hereof. In the event that any Notes have been issued in respect of the
assigned Loan or Loans, such Notes shall be marked “cancelled” and surrendered by the transferor
Bank to the Administrative Agent for return to the Borrower.

     (d) The Administrative Agent shall maintain at its address referred to in Section 10.2(a) a
copy of each Assignment and Acceptance delivered to it and a register (the “Register”) for
the recordation of the names and addresses of the Banks and the Commitments of, and

79

 

principal
amount of the Loans owing to, each Bank from time to time. To the extent permitted by applicable
law, the entries in the Register shall be conclusive, in the absence of manifest error, and the
Borrower, the Administrative Agent and the Banks may (and, in the case of any Loan or other
obligations hereunder not evidenced by a Note, shall) treat, each Person whose name is recorded in
the Register pursuant to the terms hereof as the owner of a Loan or other obligation hereunder as
the owner thereof for all purposes of this Agreement and the other Loan Documents, notwithstanding
any notice to the contrary. Any assignment of any Loan or other obligation hereunder shall be
effective only upon appropriate entries with respect thereto being made in the Register. The
Register shall be available for inspection by the Borrower or any Bank at any reasonable time and
from time to time upon reasonable prior notice.

     (e) Upon its receipt of an Assignment and Acceptance executed by a transferor Bank and
Purchasing Bank (and, in the case of a Purchasing Bank that is not then a Bank Affiliate, by the
Borrower and the Administrative Agent), together with payment to the Administrative Agent of a
registration and processing fee of $3,500, the Administrative Agent shall promptly accept such
Assignment and Acceptance on the Transfer Effective Date determined pursuant thereto, record the
information contained therein in the Register and give notice of such acceptance and recordation to
the Banks and the Borrower.

     (f) Any Bank 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 Bank, including any pledge or assignment
to secure obligations to a Federal Reserve Bank or other central banking authority, 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 Bank from any of its
obligations hereunder or substitute any such pledgee or Purchasing Bank for such Bank as a party
hereto. The Borrower hereby agrees that, upon request of any Bank at any time and from time to
time after the Borrower has made its initial Borrowing hereunder, the Borrower shall provide to
such Bank, at the Borrower’s own expense, a promissory note, substantially in the form of
Exhibit D-1 or D-2 evidencing the Loans or L/C Obligations, as the case may be, owing to
such Bank.

     SECTION 10.7. Setoff. In addition to any rights and remedies of the Banks provided by
law, if any Event of Default shall have occurred and be continuing, each Bank shall have the right,
to the fullest extent permitted by law, without prior notice to the Borrower (any such notice being
expressly waived by the Borrower to the extent permitted by applicable law), to set off and apply
any and all deposits (general or special, time or demand, provisional or final), in any currency,
and any other credits, indebtedness or claims, in any currency, in each case whether direct or
indirect, absolute or contingent, matured or unmatured, at any time held or owing by such Bank or
any branch or agency thereof to or for the credit or the account of the Borrower against any of and
all the obligations of the Borrower existing under this Agreement which are then due and payable.
Each Bank agrees promptly to notify the Borrower and the Administrative Agent after any such setoff
and application made by such Bank, provided that the failure to give such notice shall not
affect the validity of such setoff and application.

     SECTION 10.8. Counterparts. This Agreement may be executed by one or more of the
parties to this Agreement on any number of separate counterparts, and all of said counterparts
taken together shall be deemed to constitute one and the same instrument. A set of the copies of

80

 

this Agreement signed by all the parties shall be maintained with Borrower and the Administrative
Agent.

     SECTION 10.9. Severability. Any provision of this Agreement that is prohibited or
unenforceable in any jurisdiction shall, as to such jurisdiction, be ineffective to the extent of
such prohibition or unenforceability without invalidating the remaining provisions hereof, and any
such prohibition or unenforceability in any jurisdiction shall not invalidate or render
unenforceable such provision in any other jurisdiction.

     SECTION 10.10. Integration. This Agreement and the other Loan Documents represent the
agreement of the Borrower, the Administrative Agent and the Banks with respect to the subject
matter hereof, and there are no promises, undertakings, representations or warranties by the
Administrative Agent
or any Bank relative to the subject matter hereof not expressly set forth or referred to
herein or in the other Loan Documents.

     SECTION 10.11. GOVERNING LAW. (a) THIS AGREEMENT AND THE OTHER LOAN DOCUMENTS SHALL
BE GOVERNED BY, AND CONSTRUED AND INTERPRETED IN ACCORDANCE WITH, THE LAWS OF THE STATE OF NEW
YORK.

     (b) Notwithstanding anything in Section 10.11(a) to the contrary, nothing in this Agreement or
in any Note or any other Loan Documents shall be deemed to constitute a waiver of any rights which
any Bank may have under applicable federal law relating to the amount of interest which any Bank
may contract for, take, receive or charge in respect of any Loans, including any right to take,
receive, reserve and charge interest at the rate allowed by the laws of the state where such Bank
is located. To the extent that Texas law is applicable to the determination of the Highest Lawful
Rate, the Banks and the Borrower agree that (i) if Chapter 303 of the Texas Finance Code, as
amended, is applicable to such determination, the weekly rate ceiling as computed from time to time
shall apply, provided that, to the extent permitted by such Article, the Administrative
Agent may from time to time by notice to the Borrower revise the election of such interest rate
ceiling as such ceiling affects the then current or future balances of the Loans; and (ii) the
provisions of Chapter 346 of the Texas Finance Code, as amended shall not apply to this Agreement
or any Note issued hereunder.

     SECTION 10.12. Submission to Jurisdiction; Waivers. The Borrower hereby irrevocably
and unconditionally:

     (a) submits for itself and its property in any legal action or proceeding relating to this
Agreement and the other Loan Documents to which it is a party, or for recognition and enforcement
of any judgment in respect thereof, to the non-exclusive general jurisdiction of the Courts of the
State of New York sitting in New York County, the courts of the United States of America for the
Southern District of New York, and appellate courts from any thereof;

     (b) consents that any such action or proceeding may be brought in such courts and waives any
objection that it may now or hereafter have to the venue of any such action or proceeding in any
such court or that such action or proceeding was brought in an inconvenient court and agrees not to
plead or claim the same;

81

 

     (c) agrees that service of process in any such action or proceeding may be effected by mailing
a copy thereof by registered or certified mail (or any substantially similar form of mail), postage
prepaid to the Borrower at its address set forth in Section 10.2 or at such other address of which
the Administrative Agent shall have been notified pursuant thereto; and

     (d) agrees that nothing herein shall affect the right to effect service of process in any
other manner permitted by law or shall limit the right to sue in any other jurisdiction.

     SECTION 10.13. Acknowledgments. The Borrower hereby acknowledges that:

     (a) it has been advised by counsel in the negotiation, execution and delivery of this
Agreement and the other Loan Documents;

     (b) neither the Administrative Agent nor any Bank has any fiduciary relationship with or duty
to the Borrower arising out of or in connection with this Agreement or any of the other Loan
Documents, and the relationship between the Administrative Agent and the Banks, on one hand, and
the Borrower, on the other hand, in connection herewith or therewith is solely that of debtor and
creditor; and

     (c) no joint venture exists among the Banks or among the Borrower and the Banks.

     SECTION 10.14. Limitation on Agreements. All agreements between the Borrower, the
Administrative Agent or any Bank, whether now existing or hereafter arising and whether written or
oral, are hereby expressly limited so that in no contingency or event whatsoever, whether by reason
of demand being made in respect of an amount due under any Loan Document or otherwise, shall the
amount paid, or agreed to be paid, to the Administrative Agent or any Bank for the use,
forbearance, or detention of the money to be loaned under this Agreement, any Notes or any other
Loan Document or otherwise or for the payment or performance of any covenant or obligation
contained herein or in any other Loan Document exceed the Highest Lawful Rate. If, as a result of
any circumstances whatsoever, fulfillment of any provision hereof or of any of such documents, at
the time performance of such provision shall be due, shall involve transcending the limit of
validity prescribed by applicable usury law, then, ipso facto, the obligation to be fulfilled shall
be reduced to the limit of such validity, and if, from any such circumstance, the Administrative
Agent or any Bank shall ever receive interest or anything that might be deemed interest under
applicable law that would exceed the Highest Lawful Rate, such amount that would be excessive
interest shall be applied to the reduction of the principal amount owing on account of such Bank’s
Loans or the amounts owing on other obligations of the Borrower to the Administrative Agent or any
Bank under any Loan Document and not to the payment of interest, or if such excessive interest
exceeds the unpaid principal balance of such Bank’s Loans and the amounts owing on other
obligations of the Borrower to the Administrative Agent or any Bank under any Loan Document, as the
case may be, such excess shall be refunded to the Borrower. All sums paid or agreed to be paid to
the Administrative Agent or any Bank for the use, forbearance or detention of the indebtedness of
the Borrower to the Administrative Agent or any Bank shall, to the fullest extent permitted by
applicable law, be amortized, prorated, allocated and spread throughout the full term of such
indebtedness until payment in full

82

 

of the principal (including the period of any renewal or
extension thereof) so that the interest on account of such indebtedness shall not exceed the
Highest Lawful Rate. Notwithstanding anything to the contrary contained in any Loan Document, it
is understood and agreed that if at any time the rate of interest that accrues on the outstanding
principal balance of any Loan shall exceed the Highest Lawful Rate, the rate of interest that
accrues on the outstanding principal balance of any Loan shall be limited to the Highest Lawful
Rate, but any subsequent reductions in the rate of interest that accrues on
the outstanding principal balance of any Loan shall not reduce the rate of interest that
accrues on the outstanding principal balance of any Loan below the Highest Lawful Rate until the
total amount of interest accrued on the outstanding principal balance of any Loan equals the amount
of interest that would have accrued if such interest rate had at all times been in effect. The
terms and provisions of this Section 10.14 shall control and supersede every other provision of all
Loan Documents.

     SECTION 10.15. Removal of Bank. Notwithstanding anything herein or in any other Loan
Document to the contrary, the Borrower may, at any time in its sole discretion, remove any Bank
upon 15 Business Days’ written notice to such Bank and the Administrative Agent (the contents of
which notice shall be promptly communicated by the Administrative Agent to each other Bank), such
removal to be effective at the expiration of such 15-day notice period; provided,
however, that no Bank may be removed hereunder at a time when an Event of Default shall
have occurred and be continuing. Each notice by the Borrower under this Section 10.15 shall
constitute a representation by the Borrower that the removal described in such notice is permitted
under this Section 10.15. Concurrently with such removal, the Borrower shall pay to such removed
Bank all amounts owing to such Bank hereunder (including any amounts arising under Section 3.7 as a
consequence of such removal) and under any other Loan Document in immediately available funds.
Upon full and final payment hereunder of all amounts owing to such removed Bank, such Bank shall
make appropriate entries in its accounts evidencing payment of all Loans hereunder and releasing
the Borrower from all obligations owing to the removed Bank in respect of the Loans hereunder and
surrender to the Administrative Agent for return to the Borrower any Notes of the Borrower then
held by it. Effective immediately upon such full and final payment, such removed Bank will not be
considered to be a “Bank” for purposes of this Agreement, except for the purposes of any provision
hereof that by its terms survives the termination of this Agreement and the payment of the amounts
payable hereunder. Effective immediately upon such removal, the Commitment of such removed Bank
shall immediately terminate and such Bank’s participation share in any outstanding Letters of
Credit shall immediately terminate and such participation share shall be divided among the
remaining Banks according to their Revolving Percentages. Such removal will not, however, affect
the Commitments of any other Banks hereunder.

     SECTION 10.16. Confidentiality. Each of the Banks and the Administrative Agent agrees
to maintain, and to use its commercially reasonable efforts to cause any third party recipient of
the information described in this Section 10.16 to maintain, any information delivered or made
available by the Borrower to it (including any information obtained pursuant to Section 7.1),
confidential from anyone other than Persons employed or retained by such party who are or are
expected to become engaged in evaluating, approving, structuring or administering the transactions
contemplated hereunder; provided that nothing shall prevent any Bank or the Administrative Agent
from disclosing such information (i) to any other Bank or any Affiliate of any Bank, (ii) pursuant
to subpoena or upon the order of any court or administrative

83

 

agency having jurisdiction over such
Bank or the Administrative Agent, as the case may be, (iii) upon the request or demand of any
Governmental Authority or self-regulatory body, in each case, having jurisdiction
over such Bank or the Administrative Agent, as the case may be, (iv) if such information has
been publicly disclosed (other than by reason of disclosure by any Bank or the Administrative Agent
in breach of its obligations under this Section 10.16), (v) to the extent reasonably required in
connection with any litigation to which either the Administrative Agent, any Bank, the Borrower or
their respective Affiliates may be a party relating to this Agreement or any other Loan Document,
(vi) to the extent reasonably required in connection with the exercise of any remedy hereunder,
(vii) to the Administrative Agent’s or such Bank’s, as the case may be, legal counsel, independent
auditors and other professional advisors and agents involved in the administration of the Loans
hereunder, or (viii) to any actual or proposed Participant, Purchasing Bank, hedge counterparty in
respect of this Agreement or pledgee (each, a “Transferee”) that has agreed in writing to
be bound by the provisions of this Section 10.16. To the extent permitted by applicable law, in
the event that any Bank or the Administrative Agent is legally requested or required to disclose
any confidential information pursuant to clause (ii), (iii) or (v) of this Section 10.16, such
party shall promptly notify the Borrower of such request or requirement prior to disclosure so that
Borrower may seek an appropriate protective order and/or waive compliance with the terms of this
Agreement. If, however, in the opinion of counsel for such party, such party is nonetheless, in
the absence of such order or waiver, compelled to disclose such confidential information or
otherwise stand liable for contempt or suffer possible censure or other penalty or liability, then
such party may disclose such confidential information without liability to the Borrower;
provided, however, that such party will use its commercially reasonable efforts to
minimize the disclosure of such information. Subject to the exceptions above to disclosure of
information, each of the Banks and the Administrative Agent agrees that it shall not publish,
publicize, or otherwise make public any information regarding this Agreement or the transactions
contemplated hereby without the written consent of the Borrower, in its sole discretion.

     SECTION 10.17. Officer’s Certificates. It is not intended that any certificate of any
officer of the Borrower delivered to the Administrative Agent or any Bank pursuant to this
Agreement shall give rise to any personal liability on the part of such officer.

     SECTION 10.18. USA Patriot Act. Each Bank and the Administrative Agent (for itself
and not on behalf of any Bank) 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
“Patriot 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 other information
that will allow such Bank or the Administrative Agent, as applicable, to identify the Borrower in
accordance with the Patriot Act. The Borrower shall, and shall cause each of its Subsidiaries to,
provide, to the extent commercially reasonable, such information and take such actions as are
reasonably requested by each Bank and the Administrative Agent to maintain compliance with the
Patriot Act.

84

 

          SECTION 10.19. No Advisory or Fiduciary Responsibility. The Borrower acknowledges and
agrees, and acknowledges its Affiliates’ understanding, that: (a) no fiduciary, advisory or agency
relationship between the Borrower or any of its Affiliates, on the one hand, and the Administrative
Agent, any other Agent, any Lead Arranger, any Global Coordinator, any Issuing Bank, the Swingline
Lender or any Bank, on the other hand, is intended to be or has been created in respect of this
Agreement, irrespective of whether any such Person has advised or is advising the Borrower or any
of its Affiliates on other matters, (b) each of the Administrative Agent, the other Agents, the
Lead Arrangers, the Global Coordinators, the Issuing Banks, the Swingline Lender and the Banks, on
the one hand, and the Borrower and its Affiliates, on the other hand, have an arm’s length business
relationship that does not directly or indirectly give rise to, nor do the Borrower and its
Affiliates rely on, any fiduciary duty to them on the part of the Administrative Agent, any other
Agent, any Lead Arranger, any Global Coordinator, any Issuing Bank, the Swingline Lender or any
Bank, (c) the Borrower and its Affiliates are capable of evaluating and understanding, and each of
the Borrower and its Affiliates understands and accepts, the terms, risks and conditions of the
transactions contemplated by this Agreement and by the other Loan Documents, (d) the Borrower and
its Affiliates have been advised that the Administrative Agent, the other Agents, the Lead
Arrangers, the Global Coordinators, the Issuing Banks, the Swingline Lender and the Banks are
engaged in a broad range of transactions that may involve interests that differ from the interests
of the Borrower and its Affiliates and no such Person has any obligation to disclose such interests
and transactions to the Borrower or any of its Affiliates, (e) the Borrower and its Affiliates have
consulted their own legal, accounting, regulatory and tax advisors to the extent they have deemed
appropriate, and (f) each of the Administrative Agent, the other Agents, the Lead Arrangers, the
Global Coordinators, the Issuing Banks, the Swingline Lender and the Banks has been, is, and will
be acting solely as a principal and, except as otherwise expressly agreed in writing by it and the
relevant parties, has not been, is not, and will not be acting as an advisor, agent or fiduciary
for the Borrower or any of its Affiliates or any other Person or entity in respect of the
transactions contemplated by this Agreement.

85

          This CREDIT AGREEMENT (this “Agreement”), dated as of September 9, 2011, among
CENTERPOINT ENERGY RESOURCES CORP., a Delaware corporation (the “Borrower”), the banks and
other financial institutions from time to time parties hereto (individually, a “Bank” and,
collectively, the “Banks”), BANK OF AMERICA, N.A., JPMORGAN CHASE BANK, N.A. and THE ROYAL
BANK OF SCOTLAND PLC, as co-syndication agents (in such capacities, the “Co-Syndication
Agents”), BARCLAYS BANK PLC, DEUTSCHE BANK SECURITIES INC. and WELLS FARGO BANK, NATIONAL
ASSOCIATION, as co-documentation agents (in such capacities, the “Co-Documentation
Agents”), and CITIBANK, N.A., as administrative agent (in such capacity, together with any
successors thereto in such capacity, the “Administrative Agent”).

          The parties hereto hereby agree as follows:

ARTICLE I

          SECTION
1.1. Certain Defined TermsAs used in this Agreement, the following terms shall have the
following meanings:

to the Alternate Base Rate.

     “ABR Revolving Loan” means a Revolving Loan that is an ABR Loan.

     “Administrative Agent” has the meaning specified in the introduction to this
Agreement.

     “Affiliate” means any Person that, directly or indirectly, Controls or is
Controlled by or is under common Control with another Person.

     “Agents” means the collective reference to the Co-Syndication Agents, the
Co-Documentation Agents and the Administrative Agent.

     “Agreement” has the meaning specified in the introduction to this Agreement.

     “Alternate Base Rate” means, for any day, a rate per annum (rounded upwards, if
necessary, to the next 1/100 of 1%) equal to the greatest of (a) the Prime Rate in effect on
such day, (b) the Federal Funds Effective Rate in effect on such day plus 1/2 of 1% and (c)
the Eurodollar Rate for a one-month Interest Period for such day (or if such day is not a
Business Day, the immediately preceding Business Day) plus 1%; provided that, for
purposes of this definition, the Eurodollar Rate for any day shall be based on the rate
appearing on Page LIBOR01 of the Reuters screen (or on any successor or substitute page of
such service, or any successor or substitute for such service, providing rate quotations
comparable to those currently provided on such page of such service, as determined by the
Administrative Agent from time to time for purposes of providing
quotations of interest rates applicable to dollar deposits in the London interbank
market) at approximately 11:00 A.M., London time, on such day. Any change in the Alternate

 

 

Base Rate due to a change in the Prime Rate, the Federal Funds Effective Rate or the
Eurodollar Rate shall be effective as of the opening of business on the effective date of
such change in the Prime Rate, the Federal Funds Effective Rate or the Eurodollar Rate,
respectively.

     “Applicable Rate” means, for any day, with respect to any Eurodollar Rate Loan
or ABR Loan, or with respect to the Commitment Fees payable hereunder, as they case may be,
the applicable rate per annum set forth below under the caption “Eurodollar Rate Margin”,
“ABR Margin” or “Commitment Fee Rate”, as the case may be, based upon the Designated Ratings
by S&P, Moody’s and Fitch, respectively, applicable on such day:

	 	 	 	 	 	 	 	 	 	 	 	 	 
	Designated	 	Eurodollar Rate	 	 	 	 	 	 	Commitment Fee	 
	Rating	 	Margin	 	 	ABR Margin	 	 	Rate	 
	Higher than BBB+/Baa1/BBB+
	 	 	1.125	%	 	 	0.125	%	 	 	0.125	%
	BBB+/Baa1/BBB+
	 	 	1.25	%	 	 	0.25	%	 	 	0.175	%
	BBB/Baa2/BBB
	 	 	1.50	%	 	 	0.50	%	 	 	0.225	%
	BBB-/Baa3/BBB-
	 	 	1.75	%	 	 	0.75	%	 	 	0.275	%
	BB+/Ba1/BB+
	 	 	2.00	%	 	 	1.00	%	 	 	0.375	%
	Lower than BB+/Ba1/BB+
	 	 	2.25	%	 	 	1.25	%	 	 	0.50	%

     For purposes of the foregoing, (a) if the Designated Ratings are split and all
three Designated Ratings fall in different levels, the Applicable Rate shall be based upon
the middle Designated Rating; (b) if the Designated Ratings are split and two of the
Designated Ratings fall in the same level (the “Majority Level”) and the third
Designated Rating is in a different level, the Applicable Rate shall be based upon the
Majority Level; (c) if only two of the Rating Agencies issue a Designated Rating, the
Applicable Rate shall be based upon the higher of such Designated Ratings, provided
that if the higher Designated Rating is two or more levels above the lower Designated
Rating, the Applicable Rate shall be based upon the rating next below the higher of the two
Designated Ratings; (d) if only one of the three Rating Agencies issues a Designated Rating,
the Applicable Rate shall be based upon such Designated Rating; and (e) if the Designated
Ratings established by any of the three Rating Agencies shall be changed (other than as a
result of a change in the rating system of such Rating Agency), such change shall be
effective as of the date on which it is first announced by the applicable Rating Agency (it
being understood that a change in outlook status (e.g., watch status, negative outlook
status) does not constitute a change in any Designated Rating for purposes hereof). If the
rating system of any Rating Agency shall change, or if any Rating Agency shall cease to be
in the business of rating corporate debt obligations, the Borrower and the Administrative
Agent shall negotiate in good faith if necessary to amend this definition and the
definitions of “Designated Rating” and “Rating Agencies”
to reflect such changed rating system or the unavailability of Designated Ratings from
such Rating Agency and, pending the effectiveness of any such amendment, the

2

 

Applicable Rate
shall be determined by reference to the Designated Rating of such Rating Agency most
recently in effect prior to such change or cessation.

     “Application” means an application, substantially in the form attached as

issue a Letter of Credit.

Bank’s Available Commitment pursuant to Section 3.2, the aggregate principal amount of
Swingline Loans then outstanding shall be deemed to be zero.

this Agreement. Unless the context otherwise requires, the term “Banks” includes the
Swingline Lender.

     “Bank Affiliate” means, (a) with respect to any Bank, (i) an Affiliate of such

administered or managed by a Bank or an Affiliate of such Bank and (b) with respect to any
Bank that is a fund which invests in bank loans and similar extensions of credit, any other
fund that invests in bank loans and similar extensions of credit and is managed by such
Bank, an Affiliate of such Bank or the same investment advisor as such Bank or by an
Affiliate of such investment advisor.

     “Bankruptcy Event” means, with respect to any Person, such Person becomes the
subject of a bankruptcy or insolvency proceeding, or has had a receiver, conservator,
trustee, administrator, custodian, assignee for the benefit of creditors or similar Person
charged with the reorganization or liquidation of its business appointed for it, or, in the
good faith determination of the Administrative Agent, has taken any action in furtherance
of, or indicating its consent to, approval of, or acquiescence in, any such proceeding or
appointment; provided that a Bankruptcy Event shall not result solely by virtue of
any ownership interest, or the acquisition of any ownership interest, in such Person by a
Governmental Authority or instrumentality thereof, so long as such ownership interest does
not result in or provide such Person with immunity from the jurisdiction of courts within
the United States or from the enforcement of judgments or writs of attachment on its assets
or permit such Person (or such Governmental Authority or instrumentality) to reject,
repudiate, disavow or disaffirm any contracts or agreements made by such Person.

guarantees that may be incurred by endorsement of negotiable instruments for deposit or
collection in the ordinary course of business or similar transactions, (b) any obligations

     SECTION 2.1. The Commitments

     (a) Each Bank severally agrees, on the terms and subject to the conditions hereinafter set
forth, to make revolving credit loans (each such loan, a “Revolving Loan”) to the Borrower
from time to time on any Business Day during the period from the Closing Date until the
Termination Date in an aggregate principal amount that will not result in (i) such Bank’s
Outstanding Extensions of Credit exceeding such Bank’s Commitment or (ii) the Total Outstanding
Extensions of Credit exceeding the Total Commitments; provided that no Revolving

25

 

Loan shall
be made as a Eurodollar Rate Loan with an Interest Period ending after the Termination Date.

     (b) Each Revolving Borrowing shall consist of Revolving Loans of the same Type made on the
same day by the Banks ratably according to their respective Revolving Percentages. Each Revolving
Borrowing of Eurodollar Rate Loans by the Borrower shall be in an aggregate principal amount of
$5,000,000 or an integral multiple of $1,000,000 in excess thereof; provided that no more
than ten Eurodollar tranches shall be outstanding at any time. Each Revolving Borrowing of ABR

2.1. The principal amount outstanding on the Revolving Loans and all other amounts accrued
hereunder shall be due and payable on the Termination Date, together with accrued and unpaid
interest thereon.

     SECTION 2.2. Procedure for Revolving Loan Borrowing

     (a) The Borrower may borrow Revolving Loans on any Business Day during the period from and
including the Closing Date to and excluding the Termination Date, provided that the
Borrower shall give the Administrative Agent irrevocable oral notice or written notice pursuant to
a notice of borrowing, in substantially the form of Exhibit A hereto (“Notice of
Borrowing”), which shall be signed by the Borrower and shall specify therein the requested (i)
date of such Borrowing, (ii) Type of Revolving Loans comprising such Borrowing, (iii) aggregate
amount of such Borrowing and (iv) Interest Period for the Revolving Loans comprising such Borrowing
(in the case of any Borrowing of Eurodollar Rate Loans):

     (i) not later than 11:00 A.M. (New York City time) on the third Business Day prior
to the date of the proposed Borrowing in the case of a Borrowing of Eurodollar Rate Loans;

     (ii) not later than 11:00 A.M. (New York City time) on the Business Day immediately
preceding the date of the proposed Borrowing in the case of a Borrowing of Early Funding ABR
Loans; and

     (iii) not later than 11:00 A.M. (New York City time) on the same Business Day of
the proposed Borrowing in the case of a Borrowing of any other ABR Loans.

With respect to any oral notice of borrowing given by the Borrower, the Borrower shall promptly
thereafter confirm such notice in writing pursuant to a Notice of Borrowing. Upon receipt of any
such notice, the Administrative Agent shall promptly notify each Bank thereof. Each Bank shall,
before 1:00 P.M. (New York City time) on the requested Borrowing Date, make available to the
Administrative Agent at the Funding Office, in immediately available funds, such Bank’s applicable
Revolving Percentage of such Borrowing; provided, however, that, in the event of a
requested ABR Loan with respect to which the Borrower has delivered its Notice of Borrowing
on the Business Day immediately preceding the requested Borrowing Date (an “Early Funding ABR
Loan”), each Bank shall make its applicable Revolving Percentage of such Borrowing available
before 10:00 A.M. (New York City time) on the requested Borrowing Date. The

26

 

Administrative Agent
shall, no later than 2:00 P.M. (New York City time) on such date (or no later than 11:00 A.M. (New
York City time), in the case of an Early Funding ABR Loan), make available to the Borrower the
proceeds of the Revolving Loans received by the Administrative Agent hereunder by crediting such
account of the Borrower which the Administrative Agent and the Borrower shall from time to time
designate. Each Notice of Borrowing shall be irrevocable and binding on the Borrower.

     (b) Unless the Administrative Agent shall have received notice from a Bank at least two
hours prior to the applicable time described in clause (a) above by which such Bank is required to
deliver its funds to the Administrative Agent with respect to any Borrowing that such Bank will not
make available to the Administrative Agent such Bank’s applicable Revolving Percentage of such
Borrowing, the Administrative Agent may assume that such Bank has made such portion available to
the Administrative Agent on the date of such Borrowing in accordance with Section 2.2(a) and the
Administrative Agent may, in reliance upon such assumption, make available to the Borrower on such
date a corresponding amount. If such amount is made available to the Administrative Agent on a
date after such date of Borrowing, such Bank shall pay to the Administrative Agent on demand an
amount equal to the product of (i) the daily average Federal Funds Effective Rate during such
period, times (ii) the amount of such Bank’s applicable Revolving Percentage of such Borrowing,
times (iii) a fraction, the numerator of which is the number of days that elapse from and including
such date of Borrowing to the date on which such Bank’s applicable Revolving Percentage of such
Borrowing shall have become immediately available to the Administrative Agent and the denominator
of which is 360. A certificate of the Administrative Agent submitted to any Bank with respect to
any amounts owing under this Section 2.2(b) shall be conclusive in the absence of manifest error.
If such Bank shall repay to the Administrative Agent such corresponding amount, such amount so
repaid shall constitute such Bank’s Revolving Loan as part of such Borrowing for purposes of this
Agreement. If such Bank’s applicable Revolving Percentage of such Borrowing is not in fact made
available to the Administrative Agent by such Bank within one (1) Business Day of such date of
Borrowing, the Administrative Agent shall be entitled to recover such amount with interest thereon
at the rate per annum, equal to (i) the Alternate Base Rate (in the case of ABR Loans) or (ii) the
Federal Funds Effective Rate (in the case of Eurodollar Rate Loans), on demand, from the Borrower.

     (c) The failure of any Bank to make the Loan to be made by it as part of any Borrowing
shall not relieve any other Bank of its obligation, if any, hereunder to make its Loan on the date
of such Borrowing, but no Bank shall be responsible for the failure of any other Bank to make the
Loan to be made by such other Bank on the date of any Borrowing.

     SECTION 2.3. [Reserved]

the Swingline Lender of such request by telephone (confirmed pursuant to a Notice of Borrowing by
facsimile or e-mail), not later than (i) 12:00 Noon (New York City time) in the case of ABR Loans,
or (ii) 2:00 P.M. (New York City time) in the case of Money Market Rate Loans, on the day of a
proposed Swingline Loan. Each such notice shall be irrevocable and shall specify the requested
date (which shall be a Business Day), amount of the requested Swingline Loan, and whether the
requested Swingline Loan shall be an ABR Loan, a Money Market Rate Loan or a combination thereof.
The Swingline Lender shall make each Swingline Loan available to the Borrower by means of a credit
to the general deposit account of the Borrower with the Swingline Lender (or, in the case of a
Swingline Loan made to finance the reimbursement of any payment that an Issuing Bank makes under a
Letter of Credit as provided in Section 2.5(e), by remittance to the Issuing Bank) by 3:00 P.M.
(New York City time) on the requested date of such Swingline Loan.

     (c) The Swingline Lender may, by written notice given to the Administrative Agent not
later than 10:00 A.M. (New York City time) on any Business Day, require the Banks to acquire
participations on such Business Day in all or a portion of the Swingline Loans outstanding. Such
notice shall specify the aggregate amount of Swingline Loans in which Banks will participate.
Promptly upon receipt of such notice, the Administrative Agent will give notice thereof to each
Bank, specifying in such notice such Bank’s Revolving Percentage of such Swingline Loan or
Swingline Loans. Each Bank hereby absolutely and unconditionally agrees, upon receipt of notice as
provided above, to pay to the Administrative Agent, for the account of the Swingline Lender, such
Bank’s Revolving Percentage of such Swingline Loan or Swingline Loans. Each Bank acknowledges and
agrees that its obligation to acquire participations in Swingline Loans pursuant to this paragraph
is absolute and unconditional and shall not be affected by any circumstance whatsoever, including
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. Each Bank shall comply with its obligation under this paragraph by wire transfer of
immediately available funds, in the same manner as provided in Section 2.2 with respect to
Revolving Loans made by such Bank
(and Section 2.2 shall apply, mutatis mutandis, to the payment obligations of
the Bank), and the Administrative Agent shall promptly pay to the Swingline Lender the amounts so
received by it from the Banks. The Administrative Agent shall notify the Borrower of any
participations in any

28

 

Swingline Loan acquired pursuant to this paragraph, and thereafter payments
in respect of such Swingline Loan shall be made to the Administrative Agent and not to the
Swingline Lender. Any amounts received by the Swingline Lender from the Borrower (or other party
on behalf of the Borrower) in respect of a Swingline Loan after receipt by the Swingline Lender of
the proceeds of a sale of participations therein shall be promptly remitted to the Administrative
Agent; any such amounts received by the Administrative Agent shall be promptly remitted by the
Administrative Agent to the Banks that shall have made their payments pursuant to this paragraph
and to the Swingline Lender, as their interests may appear; provided that any such payment
so remitted shall be repaid to the Swingline Lender or to the Administrative Agent, as applicable,
if and to the extent such payment is required to be refunded to the Borrower for any reason. The
purchase of participations in a Swingline Loan pursuant to this paragraph shall not relieve the
Borrower of any default in the payment thereof.

     SECTION 2.5. Letters of Credit. (a) L/C Commitment.

     (i) Subject to the terms and conditions hereof (including satisfaction of the
conditions precedent set forth in Sections 5.1 (on the Closing Date) and 5.2 (upon the
issuance of each Letter of Credit)), each Issuing Bank, in reliance on the agreements of the
other Banks set forth in Section 2.5(d), agrees to issue standby letters of credit (the
“Letters of Credit”) for the account of the Borrower in support of obligations
(including performance, bid and similar bonding obligations and credit enhancement) of the
Borrower and its Affiliates on any Business Day on or after the Closing Date and prior to
the Termination Date in such form as may be approved from time to time by such Issuing Bank;
provided that no Issuing Bank shall issue any Letter of Credit if, after giving
effect to such issuance, (A) the L/C Obligations would exceed the L/C Commitment or (B) the
Total Outstanding Extensions of Credit then outstanding would exceed the Total Commitments
then in effect and provided, further, that (i) Bank of America, N.A. shall
not be required, without its consent, to issue Letters of Credit in excess of $57,500,000 at
any time outstanding and (ii) The Royal Bank of Scotland plc shall not be required, without
its consent, to issue Letters of Credit in excess of $142,500,000 at any time outstanding.

     (ii) Each Letter of Credit shall be denominated in Dollars and shall be a standby
letter of credit issued to support obligations of the Borrower or any of its Affiliates,
contingent or otherwise, and expire no later than the Maturity Date.

     (iii) No Issuing Bank shall at any time be obligated to issue any Letter of Credit
hereunder if such issuance would conflict with, or cause such Issuing Bank or any L/C
Participant to exceed any limits imposed on such Issuing Bank by, any applicable Requirement
of Law.

     (b) Procedure for Issuance of Letters of Credit. The Borrower may from time to
time request that an Issuing Bank (i) issue a Letter of Credit by delivering to such Issuing Bank
at its address for notices specified herein an Application therefor, completed to the satisfaction
of such Issuing Bank or (ii) extend, modify or increase the amount of an existing Letter of Credit
by delivering to such Issuing Bank at its address for notices specified herein a notice identifying
the Letter of Credit to be extended, modified or increased, the proposed date of such extension,

29

 

modification or increase, the name and address of the beneficiary thereof and such other
information as shall be necessary to extend, modify or increase such Letter of Credit. Upon
receipt of any Application or a request for an extension, modification or increase of an existing
Letter of Credit, the Issuing Bank will process such Application or request and shall promptly
issue the Letter of Credit (or an amendment to such existing Letter of Credit, as applicable)
requested thereby (but in no event shall any Issuing Bank be required to issue any Letter of Credit
(or extension, modification or increase of an existing Letter of Credit) earlier than two Business
Days after its receipt of the Application or request therefor, as applicable) by issuing the
original of such Letter of Credit (or amendment thereof, as applicable) in a form satisfactory to
the Borrower to the beneficiary thereof or as otherwise may be agreed by such Issuing Bank and
Borrower. The relevant Issuing Bank shall furnish a copy of such Letter of Credit (or amendment
thereof, as applicable) to the Borrower promptly following the issuance thereof and notify the
Banks of the amount thereof. In the event of any inconsistency between the terms and conditions of
this Agreement and the terms and conditions of the Application or other agreement submitted by the
Borrower to, or entered into by the Borrower with, the Issuing Bank relating to any Letter of
Credit, the terms and conditions of this Agreement shall control.

     (c) Fees, Commissions and Other Charges.

     (i) The Borrower shall pay to the Administrative Agent, for the account of the L/C
Participants in accordance with their respective Revolving Percentages, a Letter of Credit
participation fee with respect to their participations in each Letter of Credit, which shall
accrue at the rate per annum equal to the Applicable Rate for Eurodollar Rate Loans then in
effect, calculated on the basis of a 365- (or 366-, as the case may be) day year, on the
aggregate amount available to be drawn under such Letter of Credit for each day during the
period from the last L/C Fee Payment Date (or, if later, the date of issuance of such Letter
of Credit) to the date on which such payment is due hereunder. The Borrower shall pay to
the Administrative Agent, for the account of the relevant Issuing Bank, a fronting fee with
respect to each Letter of Credit issued by such Issuing Bank, which shall accrue at the rate
per annum equal to 0.20%, calculated on the basis of a 365- (or 366-, as the case may be)
day year, on the aggregate amount available to be drawn under such Letter of Credit issued
by such Issuing Bank for each day during the period from the last L/C Fee Payment Date to
the date upon which such payment is due hereunder. Such Letter of Credit participation fees
and fronting fees shall be payable in arrears on each L/C Fee Payment Date and shall be
nonrefundable.

     (ii) In addition to the foregoing fees, the Borrower shall pay or reimburse each
Issuing Bank for such normal and customary costs and reasonable expenses as are incurred or
charged by such Issuing Bank in issuing, effecting payment under, amending or otherwise
administering any Letter of Credit.

     (iii) The Administrative Agent shall, promptly following its receipt thereof,
distribute to the relevant Issuing Bank and the L/C Participants all fees received by the
Administrative Agent for their respective accounts pursuant to this Section 2.5(c).

30

 

     (d) L/C Participations.

     (i) Each Issuing Bank irrevocably agrees to grant and hereby grants to each L/C
Participant, and, to induce each Issuing Bank to issue Letters of Credit hereunder, each L/C
Participant irrevocably agrees to accept and purchase and hereby accepts and purchases from
such Issuing Bank, on the terms and conditions hereinafter stated, for such L/C
Participant’s own account and risk an undivided interest equal to such L/C Participant’s
Revolving Percentage in each Issuing Bank’s obligations and rights under each Letter of
Credit issued hereunder and the aggregate amount of drawings under Letters of Credit that
have not then been reimbursed pursuant to Section 2.5(e). Each L/C Participant
unconditionally and irrevocably agrees with each Issuing Bank that, if a draft is paid under
any Letter of Credit for which such Issuing Bank is not reimbursed in full by the Borrower
in accordance with the terms of this Agreement, such L/C Participant shall pay to such
Issuing Bank upon demand at such Issuing Bank’s address for notices specified herein an
amount equal to such L/C Participant’s Revolving Percentage of the amount of such draft, or
any part thereof, which is not so reimbursed. Each Bank acknowledges and agrees that its
obligation to acquire participations pursuant to this Section 2.5(d)(i) 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.

     (ii) If any amount required to be paid by any L/C Participant to an Issuing Bank
pursuant to Section 2.5(d)(i) in respect of any unreimbursed portion of any payment made by
such Issuing Bank under any Letter of Credit is not paid to such Issuing Bank within one
Business Day after the date such payment is due, such L/C Participant shall pay to such
Issuing Bank on demand an amount equal to the product of (A) such amount, times (B) the
daily average Federal Funds Effective Rate as quoted by the relevant Issuing Bank, during
the period from and including the date such payment is required to the date on which such
payment is immediately available to such Issuing Bank, times (C) a fraction, the numerator
of which is the number of days that elapse during such period and the denominator of which
is 360. If any such amount required to be paid by any L/C Participant pursuant to Section
2.5(d)(i) is not in fact made available to the relevant Issuing Bank by such L/C Participant
within three (3) Business Days after the date such payment is due, such Issuing Bank shall
be entitled to recover from such L/C Participant, on demand, such amount with interest
thereon calculated from such due date at the Alternate Base Rate. A certificate of the
relevant Issuing Bank submitted to any L/C Participant with respect to any amounts owing
under this subsection shall be conclusive in the absence of manifest error.

     (iii) Whenever, at any time after any Issuing Bank has made payment under any
Letter of Credit and has received from any L/C Participant its pro rata share of such
payment in accordance with Section 2.5(d)(i), such Issuing Bank receives any payment
related to such Letter of Credit (whether directly from the Borrower or otherwise, including
proceeds of collateral applied thereto by the Issuing Bank), or any payment of interest on
account thereof, such Issuing Bank will distribute to such L/C Participant its

31

 

pro rata
share thereof; provided, however, that in the event that any such payment
received by such Issuing Bank shall be required to be returned by such Issuing Bank, such
L/C Participant shall return to such Issuing Bank the portion thereof previously distributed
by such Issuing Bank to it.

     (e) Reimbursement Obligation of the Borrower. (i) The Borrower shall reimburse
each Issuing Bank for any payment that such Issuing Bank makes under a Letter of Credit on or
before the date of such payment if the Borrower receives notice of such payment at or before 10:00
A.M. (New York City time) on the date such payment is made by such Issuing Bank; provided,
however, that, if the Borrower does not receive notice of such payment at or before such
time on such date or does not reimburse such Issuing Bank under this Section 2.5(e)(i), then
Section 2.5(e)(ii) shall apply. Each such payment shall be made to the relevant Issuing Bank at
its address for notices specified herein in Dollars and in immediately available funds.

     (ii) Notwithstanding Section 5.2, each drawing under any Letter of Credit shall be
deemed to constitute a Borrowing of ABR Loans in the amount of such drawing unless the
Borrower has reimbursed the relevant Issuing Bank under Section 2.5(e)(i). The Borrowing
Date with respect to each such borrowing shall be deemed to be the date of such drawing.

     (f) Obligations Absolute.

     (i) The Borrower’s payment obligations under Section 2.5(e) shall be absolute,
irrevocable and unconditional under any and all circumstances and irrespective of any
set-off, counterclaim or defense to payment that the Borrower may have or have had against
the relevant Issuing Bank or any beneficiary of a Letter of Credit, other than a defense
based upon the gross negligence or willful misconduct as determined by a final,
non-appealable judgment of a court of competent jurisdiction.

     (ii) The Borrower also agrees with each Issuing Bank that no Issuing Bank shall be
responsible for, and the Borrower’s Reimbursement Obligations under Section 2.5(e) shall not
be affected by, among other things, (i) the validity or genuineness of documents or of any
endorsements thereon, even though such documents shall in fact prove to be invalid,
fraudulent or forged, (ii) any dispute between or among the Borrower and any beneficiary of
any Letter of Credit or any other party to which such Letter of Credit may be transferred,
(iii) any claims whatsoever of the Borrower against any beneficiary of such Letter of Credit
or any such transferee, (iv) any lack of validity or enforceability of any Letter of Credit
or this Agreement, or any term or provision therein or herein, (v) payment by the Issuing
Bank under a Letter of Credit against presentation of a draft or other document that does
not comply with the terms of such Letter of Credit or (vi) 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 or under any Letter of Credit.

     (iii) No Issuing Bank shall be liable for any error, omission, interruption or
delay in transmission, dispatch or delivery of any message or advice, however

32

 

transmitted,
in connection with any Letter of Credit, except for errors or omissions caused by such
Issuing Bank’s gross negligence or willful misconduct as determined by a final,
non-appealable judgment of a court of competent jurisdiction.

     (iv) The Borrower agrees that any action taken or omitted by any Issuing Bank under
or in connection with any Letter of Credit or the related drafts or documents, if done in
the absence of gross negligence or willful misconduct as determined by a final,
non-appealable judgment of a court of competent jurisdiction, shall be binding on the
Borrower and shall not result in any liability of such Issuing Bank to the Borrower.

     (g) Letter of Credit Payments. If any draft shall be presented for payment under
any Letter of Credit, the relevant Issuing Bank shall promptly notify the Borrower by telephone
(confirmed in writing) of the date and amount thereof and whether such Issuing Bank has made or
will make a payment thereunder. The responsibility of such Issuing Bank to the Borrower in
connection with any draft presented for payment under any Letter of Credit shall, in addition to
any payment obligation expressly provided for in such Letter of Credit, be limited to determining
that the documents (including each draft) delivered under such Letter of Credit in connection with
such presentment are in conformity with such Letter of Credit.

     (h) Application. To the extent that any provision of any Application related to
any Letter of Credit is inconsistent with the provisions of this Section 2.5, the provisions of
this Section 2.5 shall control.

     (i) Replacement, Termination or Resignation of an Issuing Bank.

     (i) Any Issuing Bank may be replaced at any time by written agreement among the
Borrower, the replaced Issuing Bank and the successor Issuing Bank. The Administrative
Agent shall notify the Banks of any such replacement of such Issuing Bank. At the time any
such replacement shall become effective, the Borrower shall pay all unpaid fees accrued for
the account of such replaced Issuing Bank pursuant to Section 2.5(c). From and after the
effective date of any such replacement, (A) the applicable successor Issuing Bank shall have
all the rights and obligations of an Issuing Bank under this Agreement with respect to
Letters of Credit to be issued thereafter and (B) 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.

     (ii) Any Issuing Bank may be terminated at any time upon not less than 10 Business
Days’ written notice by the Borrower to the Administrative Agent and such
Issuing Bank. The Administrative Agent shall notify the Banks of any such termination
of an Issuing Bank. At the time any such termination shall become effective, the Borrower
shall pay all unpaid fees accrued for the account of the terminated Issuing Bank pursuant to
Section 2.5(c). After the effective date of the termination of an Issuing Bank

33

 

hereunder,
(i) such 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 termination, but shall not be required to issue additional
Letters of Credit and (ii) if no Letter of Credit previously issued by such Issuing Bank is
then outstanding and no LC Exposure in respect of any such Letter of Credit then exists,
such terminated Issuing Bank shall not be deemed an Issuing Bank for purposes of any
provisions hereof or the other Loan Documents which require the consent or approval of each
Issuing Bank (provided that such terminated Issuing Bank’s consent shall be required for any
waiver, amendment or modification of this Agreement or any other Loan Document that affects
the rights or duties of such terminated Issuing Bank hereunder).

     (iii) Any Issuing Bank may resign as an Issuing Bank at any time after which such
Issuing Bank is no longer a Bank upon not less than 15 Business Days’ prior written notice
to the Administrative Agent and the Borrower. The Administrative Agent shall notify the
Banks of any such resignation of such Issuing Bank. At the time any such resignation shall
become effective, the Borrower shall pay all unpaid fees accrued for the account of such
resigned Issuing Bank pursuant to Section 2.5(c). From and after the effective date of any
such resignation, references herein to the term “Issuing Bank” shall be deemed to refer to
such resigned Issuing Bank if the context shall so require. After the resignation of an
Issuing Bank hereunder, the resigned 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 resignation, but shall not be
required to issue additional Letters of Credit.

     SECTION 2.6. Increase in the Total Commitments. (a) The Borrower may, without the
consent of the Banks, the Administrative Agent or the Issuing Banks, from time to time cause an
increase in the Total Commitments (each, a “Commitment Increase”), whether or not the Total
Commitments have been reduced pursuant to Section 4.5, by obtaining Commitments from one or more
additional Eligible Assignees that are not already Banks hereunder (each, a “New Bank”)
and/or by allowing one or more existing Banks to increase their respective Commitments (each, an
“Increasing Bank”); provided that (i) each Commitment Increase shall be in a
minimum amount of $10,000,000 or an integral multiple of $5,000,000 in excess thereof, (ii) each
Commitment Increase shall become effective as of a date (the “Increase Date”) that is at
least 90 days prior to the Maturity Date then in effect, (iii) no such Commitment Increase shall
result in the Total Commitments exceeding $1,425,000,000, (iv) each New Bank and each Increasing
Bank providing any portion of any Commitment Increase must be satisfactory to the Administrative
Agent and each Issuing Bank, which approval shall not be unreasonably withheld, delayed or
conditioned, (v) no Bank shall be required to provide any such increase, and (vi) on the date of
any request by the Borrower for a Commitment Increase and on the related Increase Date, the
applicable conditions set forth in Section 5.3 shall be satisfied.

     (b) Each Commitment Increase must be requested by written notice from the Borrower to the
Administrative Agent substantially in the form attached hereto as Exhibit E. Each such
notice shall specify (i) the proposed Increase Date, (ii) the amount of the requested Commitment
Increase (which amount shall conform to the requirements of Section 2.6(a)), (iii) the identity of
each New Bank and/or each Increasing Bank that is participating in such

34

 

Commitment Increase, and
(iv) the amount of the respective Commitments of the then existing Banks and the New Banks from and
after the applicable Increase Date. If the Administrative Agent and each Issuing Bank approve the
New Banks and/or Increasing Banks participating in such Commitment Increase (such approval not to
be unreasonably withheld, delayed or conditioned), the Borrower, the Administrative Agent, the
Issuing Banks and the applicable New Banks and/or Increasing Banks shall execute a Commitment
Increase Agreement, and such Commitment Increase shall be effective on the Increase Date specified
therein; provided that, as a condition to the effectiveness of any Commitment Increase, if
requested by the Administrative Agent, the Borrower shall deliver to the Administrative Agent (A)
certified copies of resolutions of the Board of Directors of the Borrower or the Executive
Committee of such Board approving such Commitment Increase and (B) opinions of counsel for the
Borrower (which may be in-house counsel), in form and substance reasonably acceptable to the
Administrative Agent, covering such matters covered by the opinions of counsel delivered pursuant
to Section 5.1(c) as the Administrative Agent may reasonably request. On each Increase Date, upon
fulfillment of the conditions set forth in the immediately preceding sentence, the Administrative
Agent shall notify the Banks (including each New Bank) and the Borrower of the occurrence of the
Commitment Increase effected on such Increase Date and shall record in the Register the relevant
information with respect to each Increasing Bank and each New Bank.

     (c) The Borrower acknowledges that, if the Total Commitments are increased on a
non-pro-rata basis pursuant to any Commitment Increase and there are any outstanding Loans as of
the Increase Date for such Commitment Increase, prepayments and/or fundings of all or portions of
certain Loans on such date may be required in order for each Bank to hold its Revolving Percentage
of each outstanding Loan after giving effect to such Commitment Increase (and any such prepayment
or funding shall be subject to the other provisions of this Agreement). Effective upon each
Commitment Increase, the amount of the participations held by each Bank in each Letter of Credit
then outstanding shall be adjusted such that, after giving effect to such adjustments, each Bank
shall hold participations in each such Letter of Credit in accordance with the Revolving Percentage
of such Bank after giving effect to such Commitment Increase.

          SECTION 2.7. Extension Option. The Borrower may request that the Commitments be extended for up to
two additional one year periods by providing not less than 30 days’ written notice (the date of
such notice, a “Notice Date”) to the Administrative Agent prior to any anniversary of the
Closing Date. If a Bank agrees, in its individual and sole discretion, to extend its Commitment
(such Bank, an “Extending Bank”), it will notify the Administrative Agent, in writing, of
its decision to do so no later than 20 days after the applicable Notice Date. The Administrative
Agent will notify the Borrower, in writing, of the Banks’ decisions no later than 25 days after
such Notice Date. The Extending Banks’ Commitments will be extended for an additional year from
the then current Maturity Date so long as (i) the Commitments of the Extending Banks (after giving
effect to any assumption by any Extending Banks of Commitments of Declining Banks as described
below), together with the Commitments of any new Banks that replace any Declining Banks, represent
more than 50% of the Total
Commitments then in effect, and (ii) on the date of any request by the Borrower to extend the
Commitments, the applicable conditions set forth in Section 5.3 shall be satisfied. No Bank shall
be required to consent to any such extension request and any Bank that declines or does not respond
to the Borrower’s request for an extension of the Commitments (a “Declining Bank”) will
have its Commitment terminated on the then existing Maturity Date (without regard to any

35

 

extension
of the Commitments of other Banks). The Borrower will have the right to accept Commitments from
any Eligible Assignee that is not a Bank in an aggregate amount up to the aggregate amount of the
Commitments of any Declining Banks; provided that (i) the Extending Banks will have the
right to increase their Commitments in an aggregate amount up to the aggregate amount of the
Declining Banks’ Commitments before the Borrower will be permitted to substitute any Eligible
Assignees for the Declining Banks and (ii) any Eligible Assignee proposed to be substituted for a
Declining Bank (unless such Eligible Assignee is an affiliate of a Bank) must be approved by the
Administrative Agent and the Issuing Banks, such approval, in each case, not to be unreasonably
withheld, delayed or conditioned. The Borrower may only extend the Maturity Date twice during the
term of this Agreement pursuant to this Section 2.7.

     SECTION 2.8. Defaulting Banks. Notwithstanding any provision of this Agreement or any
other Loan Document to the contrary, if any Bank becomes a Defaulting Bank, then the following
provisions shall apply for so long as such Bank is a Defaulting Bank:

     (a) Commitment Fees shall cease to accrue on the unfunded portion of the Commitment of
such Defaulting Bank pursuant to Section 3.2(a);

     (b) the Commitment and Outstanding Extensions of Credit of such Defaulting Bank shall not
be included in determining whether all Banks (or each Bank) or the Majority Banks have taken or may
take any action hereunder (including any consent to any amendment, waiver or other modification
pursuant to Section 10.1); provided, that this clause (b) shall not apply to the vote of a
Defaulting Bank in the case of an amendment, waiver or other modification requiring the consent of
such Bank or each Bank affected thereby if such Bank is an affected Bank; provided,
further, that there shall not be any amendment, modification or waiver (i) of any provision
of Section 4.2 or Section 10.1 in a manner that would alter the pro rata sharing of payments
required thereby, or (ii) causing the reduction of the percentage specified in the definition of
Majority Banks, or (iii) causing the consent to the assignment or transfer by the Borrower of any
of its respective rights and obligations under this Agreement and the other Loan Documents, in each
case without the consent of such Bank;

     (c) if any Swingline Exposure or L/C Obligations exist at the time such Bank becomes a
Defaulting Bank then;

     (i) all or any part of the Swingline Exposure and L/C Exposure of such
Defaulting Bank shall be reallocated (effective as of the date such Bank becomes a
Defaulting Bank) among the non-Defaulting Banks in accordance with their respective
Revolving Percentages, but only to the extent the sum of all non-Defaulting Banks’
Outstanding Extensions of Credit plus such Defaulting Bank’s Swingline Exposure and
L/C Exposure does not exceed the total of all non-Defaulting Banks’ Commitments;

     (ii) if the reallocation described in clause (i) above cannot, or can only
partially, be effected, the Borrower shall, within two Business Days following the
Borrower’s receipt of written notice by the Administrative Agent, (x) first,
prepay such Defaulting Bank’s Swingline Exposure and (y) second, cash
collateralize for the benefit of the applicable Issuing Banks only the Borrower’s
obligations

36

 

corresponding to such Defaulting Bank’s L/C Exposure (after giving
effect to any partial reallocation pursuant to clause (i) above) in accordance with
the procedures set forth in Section 8.2 for so long as such L/C Exposure is
outstanding;

     (iii) if the Borrower cash collateralizes any portion of such Defaulting
Bank’s L/C Exposure pursuant to clause (ii) above, the Borrower shall not be
required to pay any fees to such Defaulting Bank pursuant to Section 2.5(c) with
respect to such Defaulting Bank’s L/C Exposure during the period such Defaulting
Bank’s L/C Exposure is cash collateralized;

     (iv) if all or any portion of such Defaulting Bank’s L/C Exposure is
reallocated pursuant to clause (i) above, then the Letter of Credit participation
fees that otherwise would have been payable to such Defaulting Bank pursuant to
Section 2.5(c)(i) with respect to such Defaulting Bank’s reallocated L/C Exposure
shall be payable to the non-Defaulting Banks in accordance with such non-Defaulting
Banks’ Revolving Percentages after giving effect to such reallocation; and

     (v) if all or any portion of such Defaulting Bank’s L/C Exposure is neither
reallocated nor cash collateralized pursuant to clause (i) or (ii) above, then,
without prejudice to any rights or remedies of any Issuing Bank or any other Bank
hereunder, all Letter of Credit participation fees that otherwise would have been
payable to such Defaulting Bank under Section 2.5(c)(i) with respect to such
Defaulting Bank’s unreallocated L/C Exposure shall be payable to the Issuing Banks,
ratably based on the portion of such L/C Exposure attributable to Letters of Credit
issued by each Issuing Bank, until and to the extent that such L/C Exposure is
reallocated and/or cash collateralized pursuant to clause (i) or (ii) above;

     (d) so long as such Bank is a Defaulting Bank, the Swingline Lender shall not be required
to fund any Swingline Loan and no Issuing Bank shall be required to issue, amend or increase any
Letter of Credit, unless the Swingline Lender is satisfied that the related exposure in respect of
Swingline Loans, and the Issuing Banks are satisfied that the Defaulting Bank’s then outstanding
L/C Exposure, will be 100% covered by the Commitments of the non-Defaulting Banks and, to the
extent such 100% coverage is not achieved, by cash collateral which will be provided by the
Borrower in accordance with Section 2.8(c), and participating interests in any newly made Swingline
Loan or any newly issued or increased Letter of Credit shall be allocated among non-Defaulting
Banks in a manner consistent with Section 2.8(c)(i) (and such Defaulting Bank shall not participate
therein).

     If (i) a Bankruptcy Event with respect to a Parent of any Bank shall occur following the date
hereof and for so long as such event shall continue or (ii) the Swingline Lender or the Issuing
Bank has a good faith belief that any Bank has defaulted in fulfilling its obligations to extend
credit generally (such Bank referenced in clauses (i) and (ii), a “Disregarded Bank”), the
Swingline Lender shall not be required to fund any Swingline Loan and the Issuing Bank shall not be
required to issue, amend or increase any Letter of Credit, unless the Swingline Lender is

37

 

satisfied
that the related exposure in respect of Swingline Loans, and the Issuing Banks are satisfied that
the Disregarded Bank’s then outstanding L/C Exposure, will be 100% covered by the Commitments of
the non-Disregarded Banks and, to the extent such 100% coverage is not achieved, by cash collateral
which will be provided by the Borrower in the manner consistent with Section 2.8(c), and
participating interests in any newly made Swingline Loan or any newly issued or increased Letter of
Credit shall be allocated among the non-Disregarded Banks in a manner consistent with Section
2.8(c) (and such Disregarded Bank shall not participate therein).

     In the event that the Administrative Agent, the Borrower, the Swingline Lender and the Issuing
Banks each agrees that a Defaulting Bank has adequately remedied all matters that caused such Bank
to be a Defaulting Bank, then the Swingline Exposures and L/C Exposures of the Banks shall be
readjusted to reflect the inclusion of such Bank’s Commitment, and on such date such Bank shall
purchase at par such of the Revolving Loans of the other Banks as the Administrative Agent shall
determine may be necessary in order for such Bank to hold such Revolving Loans in accordance with
its Revolving Percentage.

     The rights and remedies against, and with respect to, a Defaulting Bank under this Section 2.8
are in addition to, and cumulative and not in limitation of, all other rights and remedies that the
Administrative Agent and each Lender, each Issuing Bank, the Swingline Lender or the Borrower may
at any time have against, or with respect to, such Defaulting Bank.

ARTICLE III

PROVISIONS RELATING TO ALL LOANS

     SECTION 3.1. Evidence of Loans. (a) Each Bank shall maintain in accordance with its usual
practice an account or accounts evidencing indebtedness of the Borrower to such Bank resulting from
each Loan made by such Bank from time to time, including the amounts of principal and interest
payable and paid to such Bank from time to time under this Agreement.

     (b) The Administrative Agent shall maintain the Register pursuant to Section 10.6(d) and a
subaccount therein for each Bank, in which shall be recorded (i) the amount of each Loan made by
each Bank through the Administrative Agent hereunder, the Type thereof and each 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 Bank hereunder and (iii) both the amount of any sum received
by the Administrative Agent hereunder from the Borrower and each Bank’s share thereof.

     (c) The entries made in the Register and the accounts of each Bank maintained pursuant to
Section 3.1(a) shall, to the extent permitted by applicable law, be prima facie
evidence of the existence and amount of the obligations of the Borrower therein recorded;
provided, however, that the failure of any Bank or the Administrative Agent to
maintain the Register or any such account, or any error therein, shall not in any manner affect the
obligation of the Borrower to repay (with applicable interest) the Loans actually made to the
Borrower by such Bank in accordance with the terms of this Agreement.

38

 

     (d) Any Bank may request that the Loans made by such Bank be evidenced by a Note. In such
event, the Borrower shall prepare, execute and deliver to such Bank a Note payable to such Bank.

     SECTION 3.2. Fees. (a) The Borrower agrees to pay to the Administrative Agent for the account of
each Bank a commitment fee (the “Commitment Fee”), which shall accrue at the Applicable
Rate on the Available Commitment of such Bank on each day during the period from the date hereof to
the Termination Date. The accrued Commitment Fees shall be payable (i) quarterly in arrears on the
last day of each March, June, September and December until the Termination Date and (ii) on the
Termination Date.

     (b) The Commitment Fees shall be calculated by the Administrative Agent on the basis of a
365- or 366-day year, as the case may be, for the actual days (including the first day but
excluding the last day) occurring in the period for which such Commitment Fees are payable.

     (c) The Borrower shall pay to the Administrative Agent, for its own account, the fees in
the amounts and on the dates previously agreed to in writing by the Borrower and the Administrative
Agent.

     SECTION 3.3. Interest. The Borrower shall pay interest on the unpaid principal amount of each Loan
made by each Bank from the date of such Loan until such principal amount shall be paid in full, at
the times and at the rates per annum set forth below:

     (a) ABR Loans. Each ABR Loan (excluding each Swingline Loan) shall bear interest
at a rate per annum equal at all times to the lesser of (i) the Alternate Base Rate plus
the Applicable Rate and (ii) the Highest Lawful Rate, payable quarterly in arrears on the last day
of each March, June, September and December and on the Termination Date.

     (b) Eurodollar Rate Loans. Each Eurodollar Rate Loan shall bear interest at a
rate per annum equal at all times to the lesser of (i) the sum of the Eurodollar Rate for the
applicable Interest Period for such Loan plus the Applicable Rate and (ii) the Highest
Lawful Rate, payable on the last day of such Interest Period and, with respect to Interest Periods
of six months or longer, on the ninetieth (90th) day after the commencement of the Interest Period
and on each succeeding ninetieth (90th) day during such Interest Period, and on the Termination
Date. In addition, interest on each Eurodollar Rate Loan will be payable upon any payment or
prepayment of such Eurodollar Rate Loan.

     (c) Swingline Loans. Each Swingline Loan shall bear interest at a rate per annum
equal to the lesser of (i)(A) the Alternate Base Rate plus the Applicable Rate or (B) the
Money Market Rate, at the election of the Borrower pursuant to Section 2.4, and (ii) the Highest
Lawful Rate, payable quarterly in arrears on the last day of each March, June, September and
December and on the date of payment of such Swingline Loan.

     (d) Calculations. Interest that is determined by reference to the Alternate Base
Rate (to the extent based on the Prime Rate) shall be calculated by the Administrative Agent on the
basis of a 365- or 366-day year, as the case may be, for the actual days (including the first day
but excluding the last day) occurring in the period in which such interest is payable and otherwise
shall be calculated by the Administrative Agent on the basis of a 360-day year for the

39

 

actual days
(including the first day and excluding the last day) occurring in the period for which such
interest is payable.

     (e) Default Rate. Notwithstanding the foregoing, if all or a portion of (i) the
principal amount of any Loan or Reimbursement Obligation, (ii) any interest payable thereon, or
(iii) any Commitment Fee or other amount payable hereunder shall not be paid when due (whether at
the stated maturity, by acceleration or otherwise), such overdue amount shall bear interest,
payable from time to time on demand, at a rate per annum equal to the lesser of (A) the Highest
Lawful Rate and (B) the Default Rate, in each case from the date of such non-payment until such
amount is paid in full (after as well as before judgment).

     (f) Determination Conclusive. Each determination of an interest rate by the
Administrative Agent pursuant to any provisions of this Agreement shall be conclusive and binding
on the Borrower and the Banks in the absence of manifest error. The Administrative Agent shall, at
the request of the Borrower, deliver to the Borrower a statement showing in reasonable detail the
quotations used by the Administrative Agent in determining the Eurodollar Rate.

     SECTION 3.4. Reserve Requirements. (a) The Borrower agrees to pay to each Bank that requests
compensation under this Section 3.4 in accordance with the provisions set forth in Section 4.8(b),
so long as such Bank shall be required to maintain reserves against “Eurocurrency liabilities”
under Regulation D of the Board (or, so long as such Bank shall be required by the Board or by any
other Governmental Authority to maintain reserves against any other category of liabilities that
includes deposits by reference to which the interest rate on Eurodollar Rate Loans is determined as
provided in this Agreement or against any category of extensions of credit or other assets of such
Bank that includes any Eurodollar Rate Loans), an additional amount (determined by such Bank and
notified to the Borrower pursuant to the provisions set forth in Section 4.8(b)) representing such
Bank’s calculation or, if an accurate calculation is impracticable, reasonable estimate (using such
method of allocation to such Loans of the Borrower as such Bank shall determine in accordance with
Section 4.8(a)) of the actual costs, if any, incurred by such Bank during the relevant Interest
Period as a result of the applicability of the foregoing reserves to such Eurodollar Rate Loans,
which amount in any event shall not exceed the product of the following for each day of such
Interest Period:

     (i) the principal amount of the relevant Eurodollar Rate Loans made by such Bank
outstanding on such day;

     (ii) the difference between (A) a fraction, the numerator of which is the
Eurodollar Rate(expressed as a decimal) applicable to such Eurodollar Rate Loan (expressed
as a decimal), and the denominator of which is one minus the maximum rate (expressed as a
decimal) at which such reserve requirements are imposed by the Board or other Governmental
Authority on such date, minus (B) such numerator; and

     (iii) a fraction, the numerator of which is one and the denominator of which is
360.

40

 

     (b) The agreements in this Section 3.4 shall survive the termination of this Agreement and
the payment of all amounts payable hereunder; provided, however, that in no event
shall the Borrower be obligated to reimburse or compensate any Bank for amounts contemplated by
this Section 3.4 for any period prior to the date that is 90 days before the date upon which such
Bank requests in writing such reimbursement or compensation from the Borrower.

     SECTION 3.5. Interest Rate Determination and Protection. (a) The rate of interest for each
Eurodollar Rate Loan shall be determined by the Administrative Agent two Business Days before the
first day of each Interest Period applicable to such Loan. The Administrative Agent shall give
prompt notice to the Borrower and the Banks of the applicable interest rate determined by the
Administrative Agent for purposes of Sections 3.3(a) and (b) hereof.

     (b) If, prior to the first day of any Interest Period for a Borrowing of Eurodollar Rate
Loans, (i) the Administrative Agent shall have reasonably determined (which determination shall be
conclusive and binding upon the Borrower absent manifest error) that, by reason of circumstances
affecting the London interbank Eurodollar market, adequate and reasonable means do not exist for
ascertaining the Eurodollar Rate for such Interest Period or (ii) the Administrative Agent shall
have received notice from the Majority Banks that the Eurodollar Rate determined or to be
determined for such Interest Period will not adequately and fairly reflect the cost to such Banks
(as determined in good faith and certified by such Banks) of making or maintaining their Eurodollar
Rate Loans included in such Borrowing during such Interest Period, the Administrative Agent shall
give written notice thereof to the Borrower and the Banks as soon as practicable thereafter. If
such notice is given, (A) any Eurodollar Rate Loans requested to be made on the first day of such
Interest Period shall be made as ABR Loans, (B) any Loans that were to have been converted on the
first day of such Interest Period to Eurodollar Rate Loans shall be continued as ABR Loans and (C)
any outstanding Eurodollar Rate Loans shall be converted, on the last day of the then applicable
Interest Period, to ABR Loans. Until such notice has been withdrawn by the Administrative Agent,
no further Eurodollar Rate Loans shall be made or continued as such, nor shall the Borrower have
the right to convert ABR Loans to Eurodollar Rate Loans. The Administrative Agent will withdraw
any such notice when the circumstances giving rise to such notice no longer exist.

     SECTION 3.6. Voluntary Interest Conversion or Continuation of Revolving Loans. (a) Each Borrowing initially shall be of the Type specified in the applicable Notice of
Borrowing and, in the case of a Borrowing of Eurodollar Rate Loans, shall have an initial Interest
Period as specified in such Notice of Borrowing. Thereafter, the Borrower may, at any time and
from time to time, but subject to Section 3.7 below, elect to (i) convert Revolving Loans of one
Type into Revolving Loans of another Type; (ii) convert Eurodollar Rate Loans for a specified
Interest Period into Eurodollar Rate Loans for a different Interest Period; or (iii) continue
Eurodollar Rate Loans for a specified Interest Period as Eurodollar Rate Loans for the same
Interest Period; provided, however, that (A) if an Event of Default has occurred
and is continuing and the Administrative Agent, at the request of the Majority Banks, so notifies
the Borrower, then, so long as an Event of Default is continuing, no Revolving Loan may be
converted into or continued as a Eurodollar Rate Loan, and (B) no Revolving Loan may be converted
into or continued as a Eurodollar Rate Loan if after giving effect thereto, Section 2.3 would be
contravened. This Section shall not apply to Swingline Borrowings, which may not be converted or
continued.

41

 

     (b) To make an election pursuant to this Section, the Borrower shall notify the
Administrative Agent of such request by telephone, facsimile or e-mail (i) not later than 11:00
A.M. (New York City time) on the third Business Day prior to the date of the proposed interest
conversion or continuation in the case of a conversion into or continuation of a Eurodollar Rate
Loan and (ii) not later than 11:00 A.M. (New York City time) on the Business Day preceding the
proposed interest conversion in the case of a conversion into an ABR Loan. Each telephonic notice
of interest conversion/continuation given by the Borrower under this Section 3.6(a), shall be
irrevocable and shall be confirmed promptly thereafter in writing.

     (c) Each written notice of interest conversion/continuation given by the Borrower under
this Section 3.6(a) and each confirmation of an oral notice of interest conversion/continuation
given by the Borrower under this Section 3.6(a) shall be in substantially the form of Exhibit
B hereto (“Notice of Interest Conversion/Continuation”). Each such Notice of Interest
Conversion/Continuation shall specify therein (x) the requested date of such interest conversion or
continuation; (y) the Revolving Loans to be converted or continued; and (z) if such interest
conversion or continuation involves the conversion into or continuation as Eurodollar Rate Loans,
the duration of the Interest Period for each such Eurodollar Rate Loan. If any Notice of Interest
Conversion/Continuation requests a conversion into or continuation as Eurodollar Rate Loans but
does not specify an Interest Period for such Eurodollar Rate Loans, the Borrower shall be deemed to
have selected an Interest Period of one month’s duration. Upon receipt of any such Notice of
Interest Conversion/Continuation, the Administrative Agent shall promptly notify each Bank thereof.
Each Notice of Interest Conversion/ Continuation shall be irrevocable and binding on the Borrower.

     (d) If the Borrower shall fail to deliver to the Administrative Agent a Notice of Interest
Conversion/Continuation with respect to any Borrowing of Eurodollar Rate Loans by 11:00 A.M. (New
York City time) on the third Business Day prior to the last day of the Interest Period applicable
thereto in accordance with this Section 3.6, the Administrative Agent will forthwith so notify the
Borrower and the Banks (provided that the failure to give such notice shall not affect the
conversion referred to below) and, unless such Revolving Loans are repaid as provided herein, such
Revolving Loans will automatically, on the last day of the then existing Interest Period therefor,
convert into Eurodollar Rate Loans with a one month Interest Period.

     SECTION 3.7. Funding Losses Relating to Eurodollar Rate Loans(a) The Borrower agrees, without
duplication of any other provision under this Agreement, to indemnify each Bank and to hold each
Bank harmless from any loss or expense that such Bank may sustain or incur as a consequence of (i)
default by the Borrower in payment when due of the principal amount of or interest on any
Eurodollar Rate Loan, (ii) default by the Borrower in making a borrowing of, conversion into or
continuation of any Eurodollar Rate Loan after the Borrower has given a notice requesting the same
in accordance with the provisions of this Agreement, (iii) default by the Borrower in making any
prepayment of Eurodollar Rate Loans after the Borrower has given a notice thereof in accordance
with the provisions of this Agreement or (iv) the making of a prepayment of Eurodollar Rate Loans
or the conversion of Eurodollar Rate Loans into ABR Loans, on a day that is not the last day of an
Interest Period with respect thereto or a day that is not the scheduled maturity date with respect
thereto, including in each case, any such loss or expense arising from the reemployment of funds
obtained by such Bank or from fees payable to terminate the deposits from which such funds were
obtained. The calculation of all amounts

42

 

payable to a Bank under this Section 3.7(a) shall be made
pursuant to the method described in Section 4.8(a), but in no event shall such amounts payable with
respect to any Eurodollar Rate Loan exceed the amounts that would have been payable assuming such
Bank had actually funded its relevant Eurodollar Rate Loan through the purchase of a deposit
bearing interest at the applicable Eurodollar Rate in an amount equal to the amount of such
Eurodollar Rate Loan and having a maturity comparable to the Interest Period applicable to such
Eurodollar Rate Loan; provided that each Bank may fund each of its Eurodollar Rate Loans in
any manner it sees fit, and the foregoing assumption shall be utilized only for the calculation of
amounts payable under this Section 3.7(a).

     (b) The agreements in this Section 3.7 shall survive the termination of this Agreement and
the payment of all amounts payable hereunder; provided, however, that in no event
shall the Borrower be obligated to reimburse or compensate any Bank for amounts contemplated by
this Section 3.7 for amounts accruing prior to the date that is 90 days prior to the date upon
which such Bank requests in writing such reimbursement or compensation from the Borrower.

     SECTION 3.8. Change in Legality. (a) Notwithstanding any other provision of this Agreement, if
any Bank shall notify the Administrative Agent that it has determined in good faith that the
introduction of or any change in or in the interpretation or application of any law or regulation
by any Governmental Authority (in each case occurring after the date of this Agreement) makes it
unlawful, or any central bank or other Governmental Authority asserts after the date of this
Agreement that it is unlawful, for any Bank or its applicable lending office to perform its
obligations hereunder to make Eurodollar Rate Loans or to fund or maintain Eurodollar Rate Loans
hereunder, (i) the obligation of such Bank to make, or to convert Revolving Loans into, or to
continue Eurodollar Rate Loans as, Eurodollar Rate Loans shall be suspended until the
Administrative Agent shall notify the Borrower that the circumstances causing such suspension no
longer exist; (ii) the Borrower shall, at its option, either prepay in full all Eurodollar Rate
Loans of such Bank then outstanding, or convert all such Revolving Loans to ABR Loans, on the
respective last days of the then current Interest Periods with respect to such Revolving Loans (or
within such earlier period as required by law), accompanied, in the case of any prepayments, by
interest accrued thereon and any
amounts payable under Section 3.7(a). Each Bank agrees that it will use reasonable efforts to
designate a different lending office for the Eurodollar Rate Loans due to such Bank that are
affected by this Section 3.8, if such designation will avoid the illegality described in this
Section 3.8 so long as such designation will not be disadvantageous to such Bank as determined by
such Bank in its sole discretion acting in good faith.

     (b) For purposes of this Section 3.8, a notice to the Borrower (with a copy to the
Administrative Agent) by any Bank pursuant to paragraph (a) above shall be effective on the date of
receipt thereof by the Borrower.

ARTICLE IV

INCREASED COSTS, TAXES, PAYMENTS AND PREPAYMENTS

     SECTION 4.1. Increased Costs; Capital Adequacy. (a) If, after the date of this Agreement, the
adoption of or any change in any law or regulation or

43

 

in the interpretation or application thereof
by any Governmental Authority or compliance by any Bank with any request or directive (whether or
not having the force of law) from any central bank or other Governmental Authority made subsequent
to the date of this Agreement (provided that the Dodd-Frank Wall Street Reform and Consumer
Protection Act, Basel III and all requests, rules, guidelines or directives under, or issued in
connection with, the foregoing shall be deemed to be a change in requirements of law, regardless of
the date enacted, adopted or issued):

     (i) shall subject any Bank or Issuing Bank to any tax of any kind whatsoever with
respect to this Agreement, any Letter of Credit or any Application made by it, or change the
basis of taxation of payments to such Bank or Issuing Bank in respect thereof (except for
Indemnified Taxes or Other Taxes covered by Section 4.3 and the imposition of, or any change
in the rate of, any Excluded Tax);

     (ii) shall impose, modify or hold applicable any reserve, special deposit,
compulsory loan or similar requirement against assets held by, deposits or other liabilities
in or for the account of, advances, loans or other extensions of credit by, or any other
acquisition of funds by, any office of such Bank that is not otherwise included in the
determination of the Eurodollar Rate hereunder (except for amounts covered by Section 3.4 or
any other Section hereof); or

     (iii) shall impose on such Bank any other condition;

and the result of any of the foregoing is to increase the actual cost to such Bank, by an amount
that such Bank deems to be material, of making, converting into, continuing or maintaining
Eurodollar Rate Loans or issuing or participating in Letters of Credit or to reduce any amount
receivable hereunder in respect thereof, then, in any such case, the Borrower shall promptly pay
such Bank, upon its demand in the manner set forth in Section 4.8(b), any additional amounts,
computed by such Bank in accordance with Section 4.8(a), necessary to compensate such Bank for such
actual increased cost or reduced amount receivable that is attributable to Loans or
Commitments (to the extent that such Bank has not already been compensated or reimbursed for such
amounts pursuant to any other provision of this Agreement). If any Bank becomes entitled to claim
any additional amounts pursuant to this Section 4.1(a) from the Borrower, it shall promptly notify
the Borrower, through the Administrative Agent, of the event by reason of which it has become so
entitled in the manner set forth in Section 4.8(b).

     (b) If any Bank determines in good faith that the introduction of or any change in or in
the interpretation or application by any Governmental Authority of any law or regulation regarding
capital adequacy after the date of this Agreement or compliance by such Bank or any corporation
controlling such Bank with any law or regulation or any guideline or request from any central bank
or other Governmental Authority (whether or not having the force of law) made or issued after the
date of this Agreement does or shall have the effect, as a result of such Bank’s obligations under
this Agreement or under any Letter of Credit, of reducing the rate of return on such Bank’s or such
corporation’s capital to a level below that which such Bank or such corporation could have achieved
but for such change or compliance (taking into consideration such Bank’s or such corporation’s
policies with respect to capital adequacy) by an amount deemed by such Bank to be material, the
Borrower shall pay to the Administrative Agent for the account of such Bank, from time to time as
specified by such Bank in the manner set forth in

44

 

Section 4.8(b), additional amounts, computed by
such Bank in accordance with
Section 4.8(a), sufficient to compensate such Bank or such corporation
in the light of such circumstances, to the extent that such Bank reasonably determines such
reduction in rate of return is allocable to the existence of such Bank’s obligations hereunder.

     (c) The agreements contained in this Section 4.1 shall survive the termination of this
Agreement and the payment of all amounts payable hereunder; provided, however, that
in no event shall the Borrower be obligated to reimburse or compensate any Bank for amounts
contemplated by this Section 4.1 for any period prior to the date that is 90 days prior to the date
upon which such Bank requests in writing such reimbursement or compensation from the Borrower;
provided that, to the extent that the adoption of or any change in any law or regulation or
in the interpretation or application thereof gives rise to any amount(s) contemplated by this
Section 4.1 on a retroactive basis, then the 90-day period referred to in the preceding proviso
shall be extended to include the period of retroactive effect thereof.

     SECTION 4.2. Pro Rata Treatment and Payments and Computations. (a) Each Borrowing of Loans by the
Borrower from the Banks hereunder, each payment by the Borrower on account of any commitment or
other fee, any reduction of the Commitments of the Banks and any prepayment on account of principal
and interest on the Loans shall be made pro rata according to the respective
Revolving Percentages of the Banks.

     (b) The Borrower shall make each payment (including each prepayment) hereunder, whether on
account of principal, interest, fees or otherwise, without setoff or counterclaim, not later than
12:00 Noon (New York City time) on the day when due in Dollars to the Administrative Agent at the
Funding Office in immediately available funds, except payments to be made directly to the Swingline
Lender as expressly provided herein. The Administrative Agent will promptly thereafter cause to be
distributed like funds relating to the payment of principal, interest, Letter of Credit fees or
commitment or other fees (to the extent received by
the Administrative Agent) ratably to the Banks according to the amounts of their respective
Loans, L/C Obligations and Commitments in respect of which such payment is made, and like funds
relating to the payment of any other amount payable to any Bank (to the extent received by the
Administrative Agent) to such Bank, in each case to be applied in accordance with the terms of this
Agreement.

     (c) Whenever any payment hereunder or under the Notes shall be stated to be due on a day
other than a Business Day, such payment shall be made on the next succeeding Business Day, and such
extension of time shall in such case be included in the computation of payment of interest or fees,
as the case may be; provided, however, if such extension would cause payment of
interest on or principal of Eurodollar Rate Loans to be made in the next following calendar month,
such payment shall be made on the next preceding Business Day.

     (d) Unless the Administrative Agent shall have received notice from the Borrower prior to
the date on which any payment is due to the Banks hereunder that the Borrower will not make such
payment in full, the Administrative Agent may assume that the Borrower has made such payment in
full to the Administrative Agent on such date and the Administrative Agent may, in reliance upon
such assumption, cause to be distributed to each Bank on such due date an amount equal to the
amount then due such Bank. If and to the extent the Borrower shall not have

45

 

so made such payment in
full to the Administrative Agent, each Bank shall pay to the Administrative Agent on demand an
amount equal to the product of (i) the daily average Federal Funds Effective Rate during such
period, times (ii) the amount of such Bank’s Revolving Percentage of such payment, times (iii) a
fraction, the numerator of which is the number of days that elapse from and including the date such
amount is distributed to such Bank to the date on which such Bank’s Revolving Percentage of such
payment shall have become immediately available to the Administrative Agent and the denominator of
which is 360.

     (e) If any Bank shall fail to make any payment required to be made by it pursuant to
Section 2.4(a), 2.5(a) or (e) or 9.7, then the Administrative Agent may, in its discretion and
notwithstanding any contrary provision hereof, (i) apply any amounts thereafter received by the
Administrative Agent for the account of such Bank for the benefit of the Administrative Agent, the
Swingline Lender or the Issuing Bank to satisfy such Bank’s obligations to it under such Section
until all such unsatisfied obligations are fully paid, and/or (ii) hold any such amounts in a
segregated account as cash collateral for, and application to, any future funding obligations of
such Bank under any such Section, in the case of each of clauses (i) and (ii) above, in any order
as determined by the Administrative Agent in its discretion.

     SECTION 4.3. Taxes. (a) Except as otherwise required by any requirement of law, any and all
payments by or on behalf of the Borrower hereunder or under any other Loan Document shall be made
free and clear of and without deduction or withholding for or on account of any and all present or
future taxes, levies, imposts, duties, charges, fees, deductions or withholdings, and all interest,
penalties and additions to tax with respect thereto, now or hereafter imposed, levied, collected,
withheld or assessed by any Governmental Authority (“Taxes”), excluding, in the case of
each Bank, the Administrative Agent, any Issuing Bank or any other recipient of any payment to be
made by or on account of any obligation of the Borrower hereunder or under any other Loan
Document, (i) net income Taxes, branch profits Taxes and franchise Taxes imposed on it by any
jurisdiction under the laws of which such recipient is organized, or in which its principal office
is located (or, in the case of any Bank, in which its applicable lending office is located), or
imposed as a result of a present or former connection between it and the jurisdiction (or political
subdivision or taxing authority thereof or therein) imposing such Tax (other than a connection
arising solely from such recipient having executed, delivered or performed its obligations or
received a payment under, or enforced, this Agreement or any other Loan Document), (ii) in the case
of a Bank (other than an assignee pursuant to a request by the Borrower under Section 4.7(b)), any
U.S. Federal withholding Taxes resulting from any requirement of law in effect on the date such
Bank becomes a party to this Agreement (or designates a new lending office), except to the extent
that any such Bank (or its assignor, if any) was entitled, at the time of designation of a new
lending office (or assignment), to receive additional amounts from the Borrower with respect to
such Taxes pursuant to this Section 4.3(a), (iii) United States backup withholding Taxes, (iv)
Taxes attributable to its failure to comply with Section 4.3(e) or Section 4.3(f), and (v) any U.S.
withholding Taxes imposed under FATCA (all such non-excluded Taxes imposed on or with respect to
any payment made by or on account of any obligation of the Borrower under any Loan Document being
hereinafter referred to as “Indemnified Taxes,” and all such excluded Taxes being
hereinafter referred to as “Excluded Taxes”). If the Borrower shall be required by law to
deduct or withhold any Taxes from or in respect of any sum payable hereunder or under any other
Loan Document to any Bank or the Administrative Agent, (i) to the extent such Taxes are Indemnified
Taxes or Other Taxes, the

46

 

sum payable by the Borrower shall be increased as necessary so that after
making all required deductions (including deductions applicable to additional sums payable under
this Section 4.3) the Bank or the Administrative Agent (as the case may be) receives an amount
equal to the sum it would have received had no such deductions for Indemnified Taxes or Other Taxes
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. Whenever
any Taxes or Other Taxes are payable by the Borrower pursuant to this Section 4.3, as promptly as
possible thereafter the Borrower shall send to the Administrative Agent for the account of the
relevant Bank or Administrative Agent, as the case may be, either (A) within thirty (30) days after
payment of any applicable tax, official tax receipts or notarized copies of such receipts
evidencing such payment or (B) a certificate executed by a Responsible Officer of the Borrower
confirming that such Taxes or Other Taxes have been paid, together with evidence of such payment.

     (b) In addition, the Borrower agrees to pay, in accordance with applicable law, any
present or future stamp or documentary Taxes or any other excise or property Taxes, charges or
similar levies that arise from any payment made hereunder or under any Note or from the execution,
delivery, registration or enforcement of or otherwise with respect to, this Agreement, any other
Loan Document, or the Loans and for which such Bank or the Administrative Agent (as the case may
be) has not been otherwise reimbursed by the Borrower under this Agreement (hereinafter referred to
as “Other Taxes”).

     (c) The Borrower will indemnify each Bank and the Administrative Agent for the full amount
of Indemnified Taxes or Other Taxes (including any Indemnified Taxes or Other Taxes imposed by any
jurisdiction on amounts payable under this Section 4.3) paid by such Bank or the Administrative
Agent (as the case may be) and any 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.

     (d) Each Bank shall indemnify the Administrative Agent for the full amount of any
Indemnified Taxes or Other Taxes that are attributable to such Bank and that are payable or paid by
the Administrative Agent, together with all reasonable costs and expenses arising therefrom or with
respect thereto, as determined by the Administrative Agent in good faith. A certificate as to the
amount of such payment or liability delivered to any Bank by the Administrative Agent shall be
conclusive absent manifest error.

     (e)

     (i) Each Bank (which, for purposes of this Section 4.3(e) and Section 4.3(f), shall
include any Issuing Bank) that is a “United States Person” as defined in Section 7701(a)(30)
of the Code shall deliver to the Borrower and the Administrative Agent on or before the date
on which it becomes a party to this Agreement two properly completed and duly executed
copies of IRS Form W-9 (or any successor form) certifying that such Bank is exempt from U.S.
federal withholding tax.

     (ii) Each Bank (or Transferee, if applicable) that is not a U.S. Person as defined
in Section 7701(a)(30) of the Code (a “Non-U.S. Bank”) agrees that it will

47

 

deliver
to the Borrower and the Administrative Agent (or, in the case of a Participant, to the Bank
from which the related participation shall have been purchased) (i) two duly completed and
properly executed copies of IRS Form W-8BEN, W-8ECI, W-8EXP or W-8IMY (together with any
applicable underlying IRS forms or other applicable documentation) or any successor
applicable form, as the case may be, (ii) in the case of a Non-U.S. Bank claiming exemption
from U.S. federal withholding tax under Section 871(h) or 881(c) of the Code with respect to
payments of “portfolio interest,” a statement substantially in the form of Exhibit G
and the applicable IRS Form W-8, or any subsequent versions thereof or successors thereto,
properly completed and duly executed by such Non-U.S. Bank claiming complete exemption from,
or a reduced rate of, U.S. federal withholding tax on payments under this Agreement and the
other Loan Documents, or (iii) any other form prescribed by applicable requirements of U.S.
federal income tax law as a basis for claiming exemption from or a reduction in U.S. federal
withholding tax duly completed together with such supplementary documentation as may be
prescribed by applicable requirements of law to permit the Borrower and the Administrative
Agent to determine the withholding or deduction required to be made. Such forms shall be
delivered by each Non-U.S. Bank on or before the date which it becomes a party to this
Agreement (or, in the case of any Participant, on or before the date such Participant
purchases the related participation) and from time to time thereafter upon the request of
the Borrower or the Administrative Agent. In addition, each Non-U.S. Bank also agrees to
deliver to the Borrower and the Administrative Agent two further copies of the said Form
W-8BEN, W-8ECI, W-8EXP, or W-8IMY (together with any applicable underlying IRS forms or
other applicable documentation) or any successor applicable form, as the case may be, on or
before the date that any such form expires or becomes obsolete or after the occurrence of
any event requiring a change in the most recent form or certification previously delivered
by it to the Borrower. Each Non-U.S.
Bank shall promptly notify the Borrower and the Administrative Agent at any time it
determines that it is no longer in a position to provide any previously delivered
certificate to the Borrower (or any other form of certification adopted by the U.S. taxing
authorities for such purpose). Notwithstanding any other provision of this Section 4.3(e),
a Non-U.S. Bank shall not be required to deliver any form pursuant to this Section 4.3(e)
that such Non-U.S. Bank is not legally able to deliver.

     (iii) If a payment made to a Bank under any Loan Document would be subject to U.S.
Federal withholding Tax imposed by FATCA if such Bank were to fail to comply with the
applicable reporting requirements of FATCA (including those contained in Section 1471(b) or
1472(b) of the Code, as applicable), such Bank shall deliver to the Borrower and the
Administrative Agent, at the time or times prescribed by law and at such time or times
reasonably requested by the Borrower or the Administrative Agent, such documentation
prescribed by applicable law (including as prescribed by Section 1471(b)(3)(C)(i) of the
Code) and such additional documentation reasonably requested by the Borrower or the
Administrative Agent as may be necessary for the Borrower or the Administrative Agent to
comply with its obligations under FATCA, to determine that such Bank has or has not complied
with such Bank’s obligations under FATCA or to determine the amount to deduct and withhold
from such payment. Solely for purposes of this Section 4.3(e), “FATCA” shall include any
amendments made to FATCA after the date of this Agreement.

48

 

     (f) Without limiting Section 4.3(e), a Bank 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 or reasonably requested by the Borrower or the Administrative Agent,
such properly completed and executed documentation prescribed by applicable law as will permit such
payments to be made without withholding or at a reduced rate if such Bank is legally entitled to
complete, execute and deliver such documentation; provided that a Bank shall not be
required to provide such documentation (other than such documentation set forth in Section 4.3(e))
if in such Bank’s reasonable judgment such completion, execution or submission would materially
prejudice the legal or commercial position of such Bank.

     (g) If the Administrative Agent or any Bank determines, in its sole discretion exercised
in good faith, that it has received a refund of those Taxes or Other Taxes as to which it has been
indemnified by the Borrower (including by the payment of additional amounts pursuant to this
Section 4.3), the Administrative Agent or such Bank shall within 20 days after such refund pay to
the Borrower the amount of such refund to the extent that the Borrower indemnified the
Administrative Agent or such Bank for such Taxes or Other Taxes pursuant to this Section 4.3, net
of any out-of-pocket costs of the Administrative Agent or such Bank 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 Bank,
agrees to repay the amount paid over to the Borrower pursuant to this Section 4.3(g) (plus any
penalties, interest or other charges imposed by the relevant Governmental Authority) to the
Administrative Agent or such Bank in the event the Administrative Agent or such Bank is required to
repay such refund to such Governmental
Authority. This paragraph shall not be construed to require the Administrative Agent or any
Bank 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.

     (h) The agreements in this Section 4.3 shall survive the termination of this Agreement and
the payment of all amounts payable hereunder; provided, however, that (i) in no
event shall the Borrower be obligated to reimburse or compensate any Bank for amounts contemplated
by this Section 4.3 for any period before the date that is 120 days before the date upon which such
Bank requests in writing such reimbursement or compensation from the Borrower (other than any
amounts as to which the ultimate amount of the reimbursement due could not then be determined) and
(ii) nothing contained in this Section 4.3 shall require the Borrower to pay any amount to any Bank
or the Administrative Agent in addition to that for which it has already reimbursed any Bank or the
Administrative Agent under any other provision of this Agreement.

     SECTION 4.4. Sharing of Payments, Etc. If any Bank (a “Benefitted Bank”) shall at any time
receive any payment (other than pursuant to Section 2.7, 3.4, 3.7, 4.1 or 4.3) of all or part of
its Revolving Loans, Reimbursement Obligations or participations in Swingline Loans owing to it or
interest thereon, or receive any collateral in respect thereof (whether voluntarily or
involuntarily, by setoff, pursuant to events or proceedings of the nature referred to in Section
8.1(g) or 8.1(h), or otherwise), in a greater proportion than any such payment to or collateral
received by any other Bank, if any, in respect of such other Bank’s Loans, Reimbursement
Obligations owing to it, respectively, or interest thereon, such benefitted Bank shall purchase for

49

 

cash from the other Banks a participating interest in such portion of each such other Bank’s Loans
or Reimbursement Obligations owing to it, respectively, or shall provide such other Banks with the
benefits of any such collateral, or the proceeds thereof, as shall be necessary to cause such
benefitted Bank to share the excess payment or benefits of such collateral or proceeds ratably with
each of the Banks; provided, however, that if all or any portion of such excess
payment or benefits is thereafter recovered from such benefitted Bank, such purchase shall be
rescinded, and the purchase price and benefits returned, to the extent of such recovery, but
without interest. The Borrower agrees that any Bank so purchasing a participation from another Bank
pursuant to this Section 4.4 may, to the fullest extent permitted by law, exercise all its rights
of payment (including the right of setoff) with respect to such participation as fully as if such
Bank were the direct creditor of the Borrower in the amount of such participation.

     SECTION 4.5. Optional Termination or Reduction of the Commitments. (a) Unless previously
terminated, the Commitments of the Banks to make Loans shall terminate on the Termination Date.

     (b) The Borrower shall have the right, without penalty or premium, upon at least three (3)
Business Days’ irrevocable written notice to the Administrative Agent (which shall give prompt
notice to each Bank), to terminate in whole the Commitments or permanently, from time to time, to
reduce ratably in part the unused portion of the Commitments, provided that (i) each
partial reduction shall be in the aggregate principal amount of $5,000,000 or an integral multiple
of $1,000,000 in excess thereof, (ii) no such termination or reduction shall be permitted if, after
giving effect thereto and to any prepayments made under Section 4.6 by the Borrower on the
effective date thereof, the Total Outstanding Extensions of Credit then outstanding would exceed
the Total Commitments then in effect, and (iii) any notice of termination of the Commitments may
state that such notice is conditioned upon the effectiveness of other credit facilities or the
closing of one or more securities offerings, in which case such notice may be revoked by the
Borrower (by notice to the Administrative Agent on or prior to the specified date) if such
condition is not satisfied.

          Each reduction of Commitments pursuant to this Section 4.5 shall be applied pro rata to the
Commitments of each Bank. If at any time, including after giving effect to any reduction of
Commitments pursuant to this Section 4.5, the Total Outstanding Extensions of Credit exceed the
Total Commitments, the Borrower shall be obligated, first, to prepay the Loans in the
amount of such excess, second, to cash collateralize Letters of Credit to the extent that
the aggregate amount of the L/C Obligations exceeds such Total Commitments after prepayment of all
Loans.

     SECTION 4.6. Voluntary Prepayments. The Borrower may, upon written notice delivered to the
Administrative Agent (and, in the case of prepayment of a Swingline Loan, the Swingline Lender) (i)
not later than 11:00 A.M. (New York City time) on the same Business Day, in the case of a
prepayment of ABR Revolving Loans, (ii) no later than 11:00 A.M. (New York City time) two (2)
Business Days before the date of prepayment (or such shorter or no notice as may be satisfactory to
the Administrative Agent), in the case of a prepayment of Eurodollar Rate Loans, and (iii) not
later than 12:00 Noon (New York City time) on the date of prepayment, in the case of a prepayment
of a Swingline Loan, stating the aggregate principal amount of the prepayment and the Loans to be
prepaid, prepay the outstanding principal amounts

50

 

of such Loans comprising part of the same
Borrowing in whole or ratably in part, together with accrued interest to the date of such
prepayment on the principal amount prepaid to the extent required by Section 3.3; provided,
however, that losses incurred by any Bank under Section 3.7 shall be payable with respect
to each such prepayment in the manner set forth in Section 3.7. Any such notice provided pursuant
to this Section 4.6 shall be irrevocable; provided that, if a notice of prepayment is given
in connection with a conditional notice of termination of the Commitments as contemplated by
Section 4.5(b)(iii), then such notice of prepayment may be revoked if such notice of termination is
revoked in accordance with Section 4.5(b)(iii). Partial prepayments pursuant to this Section 4.6
with respect to any Tranche of Eurodollar Rate Loans shall be in an aggregate principal amount
equal to the lesser of (a) $5,000,000 or an integral multiple of $1,000,000 in excess thereof and
(b) the aggregate principal amount of such Tranche of Eurodollar Rate Loans then outstanding, as
the case may be; provided that no partial prepayment of any Tranche of Eurodollar Rate
Loans may be made if, after giving effect thereto, Section 2.1(b) would be contravened. Partial
prepayments with respect to ABR Revolving Loans (other than Swingline Loans) shall be made in an
aggregate principal amount equal to the lesser of (i) $1,000,000 or an integral multiple of
$500,000 in excess thereof and (ii) the aggregate principal amount of ABR Revolving Loans then
outstanding, as the case may be.

     SECTION 4.7. Mitigation of Losses and Costs; Replacement of Banks. (a) Any Bank claiming reimbursement from the Borrower under any of Sections 3.4, 3.7, 4.1
and 4.3 hereof shall use reasonable efforts (including, if requested by the Borrower, reasonable
efforts to designate a different lending office of such Bank) to mitigate the amount of such
losses, costs, expenses and liabilities, if such efforts can be made and such mitigation can be
accomplished without such Bank suffering (i) any economic disadvantage for which such Bank does not
receive full indemnity from the Borrower under this Agreement or (ii) any legal or regulatory
disadvantage.

     (b) If (i) any Bank requests compensation under Section 4.1, or if the Borrower is
required to pay any additional amount to any Bank or any Governmental Authority for the account of
any Bank pursuant to Section 4.3, (ii) any Bank becomes a Defaulting Bank or (iii) any Bank refuses
to consent to any proposed amendment, modification, waiver or consent with respect to any provision
hereof that requires the unanimous approval of all Banks, or the approval of each of the Banks
affected thereby (in each case in accordance with Section 10.1), and the consent of the Majority
Banks shall have been obtained with respect to such amendment, modification, waiver or consent,
then the Borrower may, at its sole expense and effort (including payment of any applicable
processing and recordation fees), upon notice to such Bank and the Administrative Agent, require
such Bank to assign and delegate, without recourse (in accordance with and subject to the
restrictions contained in Section 10.6(c)), all its interests, rights and obligations under this
Agreement to an assignee that shall assume such obligations (which assignee may be another Bank, if
a Bank accepts such assignment); provided that (A) the Borrower shall have received (I) the
prior written consent of the Administrative Agent with respect to any assignee that is not already
a Bank hereunder (and if a Commitment is being assigned, each Issuing Bank), which consent shall
not unreasonably be withheld, conditioned or delayed, (II) the consent of such assignee to the
assignment and (III) in the case of clause (b)(iii) above, the consent of such assignee to the
proposed amendment, modification, waiver or consent, (B) such Bank shall have received payment of
all amounts owing to such Bank hereunder and under any other Loan Document (including any amounts
arising under Section 3.7

51

 

as a consequence of such assignment), (C) in the case of any such
assignment resulting from a claim for compensation under Section 4.1 or payments required to be
made pursuant to Section 4.3, such assignment will result in a reduction in such compensation or
payments, (D) prior to any such assignment, such Bank shall have taken no action under Section
4.7(a) so as to eliminate the continued need for payment of amounts owing pursuant to Section 4.1
or Section 4.3 and (E) until such time as such assignment shall be consummated, the Borrower shall
pay all additional amounts (if any) required pursuant to Section 4.1 or Section 4.3, as the case
may be. A Bank shall not be required to make any such assignment and delegation if, prior thereto,
as a result of a waiver by such Bank or otherwise, the circumstances entitling the Borrower to
require such assignment and delegation cease to apply.

     SECTION 4.8. Determination and Notice of Additional Costs and Other Amounts. (a) In determining
the amount of any claim for reimbursement or compensation under Sections 3.4, 3.7 and 4.1, each
Bank may use any reasonable averaging, attribution and allocation methods consistent with such
methods customarily employed by such Bank in similar situations.

     (b) Each Bank or, with respect to compensation claimed by it pursuant to Section 4.3, the
Administrative Agent, as the case may be, will (i) use its best efforts to notify the Borrower
through the Administrative Agent (in the case of each Bank) of any event occurring after the date
of this Agreement promptly after the occurrence thereof and (ii) notify the Borrower through the
Administrative Agent (in the case of each Bank) promptly after such Bank or the Administrative
Agent, as the case may be, becomes aware of any event occurring after the date of this Agreement,
in either case if such event (for purposes of this Section 4.8(b), a “Triggering Event”)
will entitle such Bank or the Administrative Agent, as the case may be, to compensation pursuant to
Section 3.4, 3.7, 4.1 or 4.3, as the case may be. Each such notification of a Triggering Event
shall be accompanied by a certificate of such Bank or the Administrative Agent, as the case may be,
setting forth the calculations and justification in reasonable detail such amount or amounts as
shall be necessary to compensate such Bank or the Administrative Agent, as the case may be, as
specified in Section 3.4, 3.7, 4.1 or 4.3, as the case may be, and certifying that such costs are
generally being charged by such Bank to other similarly situated borrowers under similar credit
facilities, which certificate shall be conclusive absent manifest error. The Borrower shall pay to
the Administrative Agent for the account of such Bank or to the Administrative Agent for its own
account, as the case may be, the amount shown as due on any such certificate within ten Business
Days after its receipt of the same.

ARTICLE VI

REPRESENTATIONS AND WARRANTIES

     SECTION 6.1. Representations and Warranties of the Borrower. The Borrower represents and warrants
as follows:

          (a) Organizational Status of the Borrower. The Borrower (i) is validly organized
and existing and in good standing under the laws of its jurisdiction of organization; (ii) is duly
authorized or qualified to do business in, and is in good standing in, each other jurisdiction in
which the conduct of its business or the ownership or leasing of its Property requires it to be so
authorized or qualified to do business, except where the failure to be so duly authorized or
qualified or in good standing, individually or in the aggregate, would not reasonably be expected
to have a Material Adverse Effect, and (iii) has the corporate power and authority to conduct its
business, as presently conducted.

          (b) Organizational Status of Significant Subsidiaries of the Borrower. Each
Significant Subsidiary of the Borrower (i) is validly organized and existing and in good standing
under the laws of the jurisdiction of its organization and is duly authorized or qualified to do
business in, and is in good standing in, each other jurisdiction in which the conduct of its
business or the ownership or leasing of its Property requires it to be so authorized or qualified
to do business, except where the failure to be so validly organized and existing or duly authorized
or qualified or in good standing, individually or in the aggregate, would not reasonably be
expected to have a Material Adverse Effect and (ii) has the corporate, partnership or other

55

 

requisite power and authority to conduct its business, as presently conducted, except where the
failure to have such power and authority, individually or in the aggregate, would not reasonably be
expected to have a Material Adverse Effect.

          (c) Organizational Powers. The Borrower has the corporate or other requisite
power to execute, deliver and perform and comply with its obligations under this Agreement, any
Notes and the other Loan Documents to which it is a party. This Agreement and each other Loan
Document to which the Borrower is a party have been duly executed and delivered on behalf of the
Borrower.

          (d) Authorization, No Conflict, Etc. The Borrowings by the Borrower contemplated
by this Agreement, the execution and delivery by the Borrower of this Agreement and the other Loan
Documents to which it is a party and the performance by the Borrower of its
obligations hereunder and thereunder have been duly authorized by all requisite corporate or
other requisite action on the part of the Borrower and do not and will not (i) violate any law or
any order of any court or other Governmental Authority to which the Borrower is subject, (ii)
violate the articles of incorporation or bylaws or other organizational documents (each as amended
from time to time) of the Borrower, (iii) violate or result in a default under any indenture, loan
agreement or other agreement to which the Borrower or any Restricted Subsidiary of the Borrower is
a party or by which the Borrower or any Restricted Subsidiary of the Borrower, or any of their
respective Property, is bound (except for such violations or defaults that, individually or in the
aggregate, would not reasonably be expected to have a Material Adverse Effect) or (iv) result in or
require the creation or imposition of any material Lien upon any of the Properties of the Borrower
or any Significant Subsidiary not permitted under this Agreement.

          (e) Governmental Approvals and Consents. No authorization or approval or action
by, and no notice to or filing with, any Governmental Authority is required for the due execution,
delivery and performance by the Borrower of, or for the Borrowings under, this Agreement and the
other Loan Documents to which it is a party, except (i) those that have been obtained or made and
(ii) such matters relating to performance as would ordinarily be done in the ordinary course of
business after the Closing Date.

          (f) Obligations Binding. This Agreement and the other Loan Documents to which the
Borrower is a party constitute the legal, valid and binding obligations of the Borrower,
enforceable against the Borrower in accordance with their respective terms (assuming due and valid
authorization, execution and delivery of this Agreement and such other Loan Documents by each party
other than the Borrower), except as such enforceability may be (i) limited by the effect of any
applicable bankruptcy, insolvency, reorganization, moratorium or other similar laws relating to or
affecting the enforcement of creditors’ rights generally and (ii) subject to the effect of general
principles of equity (regardless of whether such enforceability is considered in a proceeding in
equity or at law).

          (g) Use of Proceeds, Margin Stock. The proceeds of the Loans will be used by the
Borrower (i) to refinance its obligations under the Existing Facility, (ii) to support commercial
paper issued by the Borrower and (iii) for other general corporate purposes. Neither the Borrower
nor any Restricted Subsidiary of the Borrower is principally engaged in, or has as

56

 

one of its
important activities, the business of extending credit for the purpose of purchasing or carrying
any Margin Stock, and no part of the proceeds of any Loan made to the Borrower will be used for any
purpose that would violate the provisions of the margin regulations of the Board.

          (h) Title to Properties. The issued and outstanding Capital Stock owned by the
Borrower of each of its Significant Subsidiaries, whether such stock is owned directly or
indirectly through one or more of its Subsidiaries, is owned free and clear of any Lien. In
addition, each of the Borrower and each Significant Subsidiary has good title to, or valid
leasehold interests in, all its real and personal property material to its business, except for
defects in title and exceptions to leasehold interests that either individually or in the aggregate
would not reasonably be expected to result in a Material Adverse Effect, and all such Properties
are free and clear of any Lien except Liens permitted under this Agreement.

          (i) Investment Company Act. Neither the Borrower nor any Restricted Subsidiary of
the Borrower is an “investment company” as defined in, or otherwise subject to regulation under,
the Investment Company Act of 1940, as amended.

          (j) Material Adverse Change. Since December 31, 2010, there has been no event,
development or circumstance that, as of the Closing Date, has had, or would reasonably be expected
to have, a Material Adverse Effect.

          (k) Litigation. As of the Closing Date, there is no litigation, action, suit,
investigation or other legal or governmental proceeding by or before any arbitrator or Governmental
Authority pending against or, to the best knowledge of the Borrower, threatened against the
Borrower or any of its Subsidiaries, at law or in equity, (i) relating to the transactions under
this Agreement or under any other Loan Document or (ii) as to which there is a reasonable
possibility of an adverse decision that would have a Material Adverse Effect.

          (l) ERISA. There is no event or events, individually or in the aggregate, that
could reasonably be expected to have a Material Adverse Effect, arising out of or in connection
with (i) any Reportable Event or “accumulated funding deficiency” (within the meaning of Section
412 of the Code or Section 302 of ERISA) with respect to any Plan that has occurred during the
five-year period immediately preceding the date on which this representation is made or deemed
made, (ii) any failure of a Plan to comply with the applicable provisions of ERISA and the Code,
(iii) any termination of a Single Employer Plan, (iv) any complete or partial withdrawal by the
Borrower or any Commonly Controlled Entity from any Multiemployer Plan, (v) any Lien in favor of
the PBGC or any Plan that has arisen during the five-year period referred to in clause (i) above or
(vi) a Multiemployer Plan being in Reorganization or being Insolvent.

          (m) Financial Statements. The consolidated financial statements of the Borrower
as of and for the fiscal quarter ended June 30, 2011 filed with the SEC with the Borrower’s 10-Q
for the period then ended, copies of which have been delivered to the Banks, present fairly in all
material respects the consolidated financial condition and results of operations of the Borrower
and its Subsidiaries as of such date and for the period then ended, in conformity with, as
applicable, GAAP and, except as otherwise stated therein, consistently applied (in the case of such
unaudited statements, subject to year-end adjustments and the exclusion of detailed footnotes).

57

 

          (n) Accuracy of Information. None of the documents or written information
(excluding estimates, financial projections and forecasts) furnished to the Banks by the Borrower
in connection with or pursuant to this Agreement or the other Loan Documents (collectively, the
“Information”), contained, as of the date such Information was furnished (or, if such Information
expressly related to a specific date, as of such specific date), any untrue statement of a material
fact or omitted to state, as of the date such Information was furnished (or, if such Information
expressly related to a specific date, as of such specific date), any material fact (other than
industry-wide risks normally associated with the types of businesses conducted by the Borrower and
its Subsidiaries) necessary to make the statements therein, in the light of the circumstances under
which they were made, not materially misleading, as a whole. The estimates, financial projections
and forecasts furnished to the Banks by the Borrower with respect to the transactions contemplated
under this Agreement were prepared in good faith and on the basis of information
and assumptions that the Borrower believed to be reasonable as of the date such information
was prepared (it being recognized by the Banks that such estimates, financial projections and
forecasts as they relate to future events are not to be viewed as fact and that actual results
during the period or periods covered by such estimates, financial projections and forecasts may
differ from the projected results set forth therein by a material amount).

          (o) No Violation. The Borrower is not in violation of any order, writ, injunction
or decree of any court or any order, regulation or demand of any Governmental Authority that,
individually or in the aggregate, reasonably could be expected to have a Material Adverse Effect.

          (p) Subsidiaries. Schedule 6.1(p) attached hereto sets forth each
Significant Subsidiary as of the date hereof. Except as disclosed on Schedule 6.1(p), as
of the date hereof the Borrower owns, directly or indirectly through one or more of its
Subsidiaries, all of the outstanding Capital Stock of each Significant Subsidiary, in each case
free and clear of any Liens not permitted under this Agreement.

          (q) Senior Indebtedness. The Indebtedness of the Borrower under this Agreement
constitutes “Senior Debt” (or a similar term) of the Borrower under any indenture governing any
Junior Subordinated Debt.

          (r) Taxes. Each of the Borrower and its Subsidiaries has filed or caused to be
filed all Federal, state and all other material tax returns that are required to be filed by it and
has paid or caused to be paid all taxes shown to be due and payable on said returns or on any
assessments made against it or any of its Property and all other taxes, fees or other charges
imposed on it or any of its Property by any Governmental Authority (other than any such taxes the
amount or validity of which are currently being contested in good faith by appropriate proceedings
and with respect to which reserves in conformity with GAAP have been provided on the books of the
Borrower or its Subsidiaries), except where the failure to do so could not, individually or in the
aggregate, reasonably be expected to have a Material Adverse Effect; no tax Lien has been filed,
and to the knowledge of the Borrower, no claim is being asserted, with respect to any such tax, fee
or other charges (other than any Liens or claims that could not, individually or in the aggregate,
reasonably be expected to have a Material Adverse Effect).

7.1(a)(i), a certificate signed by a Responsible Officer of the Borrower identifying those
Subsidiaries of the Borrower which, determined as of the date of such financial statements,
are Significant Subsidiaries; and

     (vii) promptly after any request therefor, such other information relating to the
Borrower or its business, properties, condition and operations as the Administrative Agent
(or any Bank through the Administrative Agent) may reasonably request.

Information required to be delivered pursuant to the foregoing Sections 7.1(a)(i), (ii), and (iv)
shall be deemed to have been delivered on the date on which the Borrower provides notice (including
notice by e-mail) to the Administrative Agent (which notice the Administrative Agent will convey
promptly to the Banks) that such information has been posted on the SEC website on the Internet at
sec.gov/edgar/searches.htm or at another website identified in such notice and accessible by the
Banks without charge; provided that (x) such notice may be included in a certificate

60

 

Borrower shall
deliver paper copies of such information to the Administrative Agent, and the Administrative Agent
shall deliver paper copies of such information to such Bank.

          (b) Use of Proceeds. The Borrower will use the proceeds of the Loans only
for the purposes set forth in Section 6.1(g), and it will not use any Letter of Credit or the
proceeds of any Loan for any purpose that would violate the provisions of the margin regulations of
the Board. The Borrower will not, and will not permit any of its Subsidiaries to, engage
principally, or as one of its important activities, in the business of extending credit for the
purpose of purchasing or carrying, within the meaning of Regulation U, any Margin Stock.
Letters of Credit will be issued only to support the general corporate purposes of the
Borrower and its Subsidiaries.

          (c) Existence; Laws. The Borrower will, and will cause each Significant
Subsidiary to, do or cause to be done all things necessary to preserve, renew and keep in full
force and effect its legal existence and all rights, licenses, permits and franchises;
provided that the foregoing shall not prohibit any merger, consolidation, liquidation or
dissolution otherwise permitted under this Agreement; and provided further that
neither the Borrower nor any Significant Subsidiary shall be required to preserve or maintain any
rights, licenses, permits or franchises if the failure to maintain and preserve the same would not
reasonably be expected, individually or in the aggregate, to result in a Material Adverse Effect.
The Borrower will, and will cause each of its Significant Subsidiaries to, comply with all laws and
regulations applicable to it, except where the failure to do so, individually or in the aggregate,
would not reasonably be expected to have a Material Adverse Effect.

          (d) Maintenance of Properties. The Borrower will, and will cause each Significant
Subsidiary to, preserve and maintain all of its Property that is material to the conduct of the
business of the Borrower and its Subsidiaries, taken as a whole, provided, however,
that nothing in this Section 7.1(d) shall prevent the Borrower or any of its Significant
Subsidiaries from (i) selling, abandoning or otherwise disposing of any Properties (including the
Capital Stock of any Subsidiary of the Borrower that is not a Significant Subsidiary) if (x) the
retention of such Properties in the good faith judgment of the Borrower or such Significant
Subsidiary is inadvisable or unnecessary to the business of the Borrower and its Subsidiaries,
taken as a whole, or (y) the failure to preserve and maintain such Properties would not reasonably
be expected to have a Material Adverse Effect or (ii) engaging in any other transaction that is
expressly permitted by the terms of any other provision of this Agreement.

          (e) Maintenance of Business Line. The Borrower will maintain its fundamental
business of providing services and products in the energy market.

          (f) Books and Records; Access. The Borrower will, and will cause each Significant
Subsidiary to, keep proper books of record and account in which complete and accurate entries, in
all material respects, are made of its financial and business transactions to the extent required
by GAAP. The Borrower will, and will cause each of its Significant Subsidiaries to, at any
reasonable time and from time to time, permit up to six representatives of the Banks designated by
the Majority Banks, or representatives of the Administrative Agent, on not less than five Business
Days’ notice, to examine and make copies of and abstracts from the records and books of account of,
and visit the properties of, the Borrower and each Significant

61

 

Subsidiary and to discuss the
general business affairs of the Borrower and each of its Significant Subsidiaries with their
respective officers and independent certified public accountants (provided that, so long as
no Default or Event of Default shall have occurred and be continuing, the Borrower shall have the
opportunity to be present at any such discussion with such independent certified public
accountants); subject, however, in all cases to the imposition of such conditions as the Borrower
and each of its Significant Subsidiaries shall deem necessary based on reasonable considerations of
safety and security; provided, however, that neither the Borrower nor any of its
Significant Subsidiaries shall be required to disclose to any Agent, any Bank or any agents or
representatives thereof any information which is the subject of attorney-client privilege
or attorney work-product privilege properly asserted by the applicable Person to prevent the
loss of such privilege in connection with such information or which is prevented from disclosure
pursuant to a confidentiality agreement with third parties. Notwithstanding the foregoing, none of
the conditions precedent to the exercise of the right of access described in the preceding sentence
that relate to notice requirements or limitations on the Persons permitted to exercise such right
shall apply at any time when a Default or an Event of Default shall have occurred and be
continuing.

          (g) Insurance. The Borrower will, and will cause each Significant Subsidiary to,
maintain insurance with responsible and reputable insurance companies or associations, or to the
extent that the Borrower or such Significant Subsidiary deems it prudent to do so, through its own
program of self-insurance, in such amounts and covering such risks as is usually carried by
companies engaged in similar businesses, of comparable size and financial strength and with
comparable risks.

          (h) Credit Rating. The Borrower will deliver to the Administrative Agent notice
of any change by a Rating Agency in the Designated Rating assigned by such Rating Agency promptly
upon the effectiveness of such change.

     SECTION 7.2. Negative Covenants. The Borrower covenants that, so long as any amount is owing to
the Banks hereunder or under any other Loan Document to which it is a party (other than indemnities
and other contingent obligations not then due and payable and as to which no claim has been made)
or any Letter of Credit is outstanding under this Agreement or any Bank shall have any Commitment
outstanding under this Agreement:

          (a) Financial Covenant. The Borrower will not permit, as of the last day of any
fiscal quarter, the ratio of Consolidated Indebtedness for Borrowed Money as of such date to
Consolidated Capitalization as of such date to exceed 65%.

          (b) Certain Liens. The Borrower will not, and will not permit any of its
Significant Subsidiaries to, pledge, mortgage, hypothecate or grant a Lien upon, or permit any
mortgage, pledge, security interest or other Lien upon, any Property of the Borrower or any
Significant Subsidiary of the Borrower; provided, however, that this restriction
shall neither apply to nor prevent the creation or existence of:

     (i) Permitted Liens;

62

 

     (ii) any Lien in existence on the date hereof; provided that (A) no such
Lien described in this clause (ii) encumbers any additional Property after the date hereof
(other than repairs, renewals, replacements, additions, accessions, improvements and
betterments to the Property originally subject to such Lien) and (ii) the principal amount
of Indebtedness of the Borrower and its Subsidiaries secured thereby is not increased after
the date hereof (except that, if such Indebtedness is refinanced, refunded, renewed or
extended after the Closing Date, the principal amount thereof may be increased by an amount
necessary to pay all accrued and unpaid interest on such Indebtedness being
refinanced, refunded, renewed or extended and any fees and expenses, including
premiums, related to such refinancing, refunding, renewal or replacement);

     (iii) Liens required to be granted pursuant to “equal and ratable” clauses existing
on the date hereof under Contractual Obligations of the Borrower and its Significant
Subsidiaries (and extensions and renewals thereof);

     (iv) Liens arising in connection with the securitization of accounts receivable of
the Borrower and its Subsidiaries to the extent affecting only the accounts receivable of
the Borrower and its Subsidiaries and assets customarily related thereto;

     (v) Liens on fixed or capital assets and related inventory and intangible assets
acquired, constructed, improved, altered or repaired by the Borrower or any Significant
Subsidiary; provided that (i) such Liens secure Indebtedness otherwise permitted by
this Agreement, (ii) such Liens and the Indebtedness secured thereby are incurred prior to
or within 365 days after such acquisition or the later of the completion of such
construction, improvement, alteration or repair or the date of commercial operation of the
assets constructed, improved, altered or repaired, (iii) the Indebtedness secured thereby
does not exceed the cost of acquiring, constructing, improving, altering or repairing such
fixed or capital assets, as the case may be, and (iv) such Lien shall not apply to any other
property or assets of the Borrower or of its Significant Subsidiaries (other than repairs,
renewals, replacements, additions, accessions, improvements and betterments thereto);

     (vi) Liens on Property and repairs, renewals, replacements, additions, accessions,
improvements and betterments thereto existing at the time such Property is acquired by the
Borrower or any Significant Subsidiary and not created in contemplation of such acquisition
(or on repairs, renewals, replacements, additions, accessions and betterments thereto), and
Liens on the Property of any Person at the time such Person becomes a Significant Subsidiary
of the Borrower and not created in contemplation of such Person becoming a Significant
Subsidiary of the Borrower (or on repairs, renewals, replacements, additions, accessions and
betterments thereto);

     (vii) rights reserved to or vested in any Governmental Authority by the terms of
any right, power, franchise, grant, license or permit, or by any Requirements of Law, to
terminate such right, power, franchise, grant, license or permit or to purchase, condemn,
expropriate or recapture or to designate a purchaser of any of the Property of the Borrower
or any of its Significant Subsidiaries;

63

 

     (viii) rights reserved to or vested in (or exercised by) any Governmental Authority
to control, regulate or use any Property of a Person or its activities, including zoning,

     (ix) Liens on Property of the Borrower or any of its Significant Subsidiaries
securing non-recourse Indebtedness of the Borrower or any such Significant Subsidiary;

     (x) any extension, renewal or refunding of any Lien permitted by clauses (i)
through (ix) above on the same Property previously subject thereto; provided that no
extension, renewal or refunding of any such Lien shall increase the principal amount of
any Indebtedness secured thereby immediately prior to such extension, renewal or
refunding, unless such Indebtedness is permitted under Section 7.2(a);

     (xi) Liens on cash collateral to secure obligations of the Borrower and its
Significant Subsidiaries in respect of cash management arrangements with any Bank or
Affiliate thereof; and

     (xii) Liens not otherwise permitted by this Section 7.2(b) securing Indebtedness
and other obligations of the Borrower and its Significant Subsidiaries so long as the
aggregate outstanding principal amount of the Indebtedness and obligations secured thereby
does not at any time exceed at the time of incurrence of such Indebtedness or obligations
(including any such incurrence resulting from any extension, renewal or refunding of such
Indebtedness or obligations), as to the Borrower and all of its Significant Subsidiaries,
12.5% of Net Tangible Assets.

          (c) Consolidation, Merger or Disposal of Assets. The Borrower will not, and will
not permit any Significant Subsidiary to, (i) merge into or consolidate with any other Person; (ii)
liquidate, wind up or dissolve (or suffer any liquidation or dissolution); or (iii) sell, transfer,
lease or otherwise dispose of all or substantially all of its Properties to any Person;
provided, however, that (A) the Borrower may merge into, or consolidate with, any
Person if the Borrower is the surviving entity; (B) any Significant Subsidiary may consolidate with

of the Borrower if the surviving entity is such Significant Subsidiary or a Wholly-Owned Restricted
Subsidiary; (C) any Significant Subsidiary may consolidate with or merge into any Person other than
the Borrower or another Subsidiary of the Borrower if (1) such Significant Subsidiary is the
surviving entity or (2) such other Person is the surviving entity and becomes a Wholly-Owned
Restricted Subsidiary contemporaneously with such consolidation or merger; (D) any Significant
Subsidiary may liquidate, wind up or dissolve if the Properties of such Significant Subsidiary are
conveyed, transferred or distributed pursuant to such liquidation, winding up or dissolution to the
Borrower or a Wholly-Owned Restricted Subsidiary; (E) any Significant Subsidiary may sell,
transfer, lease or otherwise dispose of all or substantially all of its Properties to the Borrower,
to another Wholly-Owned Restricted Subsidiary or to a Person that becomes a Wholly-Owned Restricted
Subsidiary contemporaneously with such sale, transfer, lease or other disposition; and (F) the
Borrower and any Significant Subsidiary may make Permitted MLP/JV Asset Transfers; provided
that (x) in each case, immediately before and after giving effect to any such merger or
consolidation, dissolution or liquidation, or sale, transfer, lease or other disposition, no
Default or Event of Default shall have occurred and be continuing and (y) in the case of any
transaction

64

 

described in foregoing clause (A) or (F) (excluding, in the case of clause (A), any
transaction in which any Subsidiary of the Borrower merges into or consolidates with the Borrower),
after giving effect to such transaction, the Borrower shall be in pro forma compliance with Section
7.2(a).

          (d) Takeover Bids. The Borrower will not use the proceeds of any Loan made to it
to participate in any unsolicited control bid for any other Person.

          (e) Sale of Significant Subsidiary Stock. The Borrower will not, and will not
permit any Significant Subsidiary to, sell, assign, transfer or otherwise dispose of any of the

assign, transfer or otherwise dispose of (i) any of the Capital Stock of any Significant Subsidiary
to the Borrower or to a Wholly-Owned Subsidiary of the Borrower that constitutes a Significant
Subsidiary after giving effect to such transaction and (ii) any of the Capital Stock of any
Subsidiary that is not a Significant Subsidiary; (y) any Significant Subsidiary shall have the
right to issue, sell, assign, transfer or otherwise dispose of for value its preference or

immediately before and after giving effect to any such sale, assignment, transfer or other
disposition described in the foregoing clauses (x), (y) and (z), no Default or Event of Default
shall have occurred and be continuing and (B) in the case of any such Permitted MLP/JV Asset
Transfer permitted under the foregoing clause (z), after giving effect to such Permitted MLP/JV
Asset Transfer, the Borrower shall be in pro forma compliance with Section 7.2(a).

          (f) Agreements Restricting Dividends. The Borrower will not, and will not permit
any Significant Subsidiary to, enter into, incur or permit to exist any agreement or other
consensual arrangement that explicitly prohibits or restricts the payment by any Significant
Subsidiary of dividends or other distributions with respect to any shares of its Capital Stock;
provided that the foregoing shall not prohibit financial incurrence, maintenance and
similar covenants that indirectly have the practical effect of prohibiting or restricting the
ability of a Significant Subsidiary to make such payments or provisions that require that a certain
amount of capital be maintained, or prohibit the return of capital to shareholders above certain
dollar limits; provided further, that the foregoing shall not apply to (i)
prohibitions and restrictions imposed by law or by this Agreement, (ii) prohibitions and
restrictions contained in, or existing by reason of, any agreement or instrument existing on the
Closing Date, (iii) prohibitions and restrictions contained in, or existing by reason of, any

under an agreement or instrument referred to in clauses (ii) and (iii) above, so long as the
prohibitions or restrictions contained in any such renewal, extension, refinancing, refund or
replacement agreement, taken as a whole, are not materially more restrictive than the prohibitions
and restrictions contained in the original agreement or instrument, as determined in good faith by
a Responsible Officer of the Borrower, (v) any

65

 

prohibitions or restrictions with respect to a
Significant Subsidiary imposed pursuant to an agreement that has been entered into in connection
with a disposition of all or substantially all of the Capital Stock or assets of such Subsidiary,
(vi) any prohibitions or restrictions in respect of preferred or preference stock permitted to be

if such restrictions are not applicable to the property or assets of any other entity.

          (g) Certain Investments, Loans, Advances, Guarantees and Acquisitions. The
Borrower will not, and will not permit any of its Significant Subsidiaries to, (i) purchase or

Tangible Assets.

ARTICLE VIII

EVENTS OF DEFAULT

     SECTION 8.1. Events of Default. The occurrence of any of the following events shall constitute an

pay, in the manner provided in this Agreement, (i) any principal or Reimbursement Obligations
payable by it hereunder when due or (ii) any interest payment, any Commitment Fee or any Letter of
Credit fee payable by it hereunder within five (5) Business Days after its due date; or

          (b) Non-Payment of Other Amounts. The Borrower fails to pay, in the manner
provided in this Agreement, any other amount (other than the amounts set forth in Section 8.1(a)
above) payable by it hereunder when due and such default shall continue unremedied for a period of
at least ten (10) Business Days after the Borrower’s receipt of notice from the Administrative
Agent of such default; or

          (c) Breach of Representation or Warranty. Any representation or warranty by the

66

remedies, reliefs or other matters for which any case, proceeding or other action referred to in
clause (i) above is commenced; or (iii) there shall be commenced against the Borrower or any
Significant Subsidiary any case, proceeding or other action seeking issuance of a warrant of

an aggregate amount in excess of $75,000,000 (to the extent not covered by insurance) shall be
rendered by one or more courts of competent jurisdiction against the Borrower or any Significant
Subsidiary, and the same shall remain undischarged for a period of 60 days during which the

          (k) Change in Control. A Change in Control shall have occurred.

     SECTION 8.2. Cancellation/Acceleration. If at any time and for any reason (whether within or
beyond the control of any party to this Agreement):

68

 

     (a) either of the Events of Default specified in Section 8.1(g) or 8.1(h) occurs with
respect to the Borrower, then automatically:

     (i) the Commitments shall immediately be cancelled; and

     (ii) all Loans made hereunder, all amounts of L/C Obligations (whether or not the
beneficiaries of the then outstanding Letters of Credit shall have presented the
documents required for draws thereunder), all unpaid accrued interest or fees and any
other sum payable under this Agreement or any other Loan Document shall become immediately
due and payable; or

     (b) any other Event of Default specified in Section 8.1 occurs, then, at any time
thereafter while such Event of Default is continuing, the Administrative Agent shall, upon the
instruction of the Majority Banks, by notice to the Borrower, declare that:

     (i) the Commitments shall immediately be cancelled; and/or

     (ii) either (A) all Loans made hereunder, all amounts of L/C Obligations (whether
or not the beneficiaries of the then outstanding Letters of Credit shall have presented the
documents required for draws thereunder), all unpaid accrued interest or fees and any other
sum payable under this Agreement or any other Loan Document shall become immediately due and
payable or (B) all Loans made hereunder, all amounts of L/C Obligations (whether or not the
beneficiaries of the then outstanding Letters of Credit shall have presented the documents
required for draws thereunder), all unpaid accrued interest or fees and any other sum
payable under this Agreement or any other Loan Document shall become due and payable at any
time thereafter immediately on demand by the Administrative Agent (acting on the
instructions of the Majority Banks).

          With respect to all Letters of Credit with respect to which presentment for honor shall not
have occurred at the time of an acceleration pursuant to the preceding paragraph or on the
Termination Date, the Borrower shall at such time deposit in a cash collateral account opened by
the Administrative Agent cash or cash equivalents in an amount equal to the aggregate then undrawn
and unexpired face amount of such Letters of Credit. The Borrower hereby grants to the
Administrative Agent, for the benefit of the applicable Issuing Bank and the L/C Participants, a
security interest in such cash collateral to secure all obligations of the Borrower under this
Agreement and the other Loan Documents. Interest shall accrue on amounts deposited in such account
for the benefit of the Borrower at a rate equal to the Federal Funds Effective Rate. Amounts held
in such cash collateral account shall be applied by the Administrative Agent to the payment of
drafts drawn under such Letters of Credit, and the unused portion thereof after all such Letters of
Credit shall have expired or been fully drawn upon, if any, shall be applied to repay other
obligations of the Borrower hereunder and under the Notes. After all such Letters of Credit shall
have expired or been fully drawn upon, all Reimbursement Obligations shall have been satisfied and
all other obligations of the Borrower hereunder and under the Notes shall have been paid in full,
the balance, if any, in such cash collateral account shall be returned to the Borrower. The
Borrower shall execute and deliver to the Administrative Agent, for the account of each Issuing
Bank and the L/C Participants, such further documents and instruments as the

69

 

Administrative Agent
may reasonably request to evidence the creation and perfection of the within security interest in
such cash collateral account.

Except as expressly provided above in this Section 8.2, presentment, demand, protest, notice of
intent to accelerate, notice of acceleration and all other notices of any kind whatsoever are
hereby expressly waived by the Borrower.

ARTICLE IX

THE ADMINISTRATIVE AGENT

          SECTION
9.1. Authorization and Action Each Bank and Issuing Bank hereby appoints and authorizes the
Administrative Agent to take such action as agent on its behalf and to exercise such powers and
discretion under this Agreement and the other Loan Documents as are delegated to the Administrative
Agent by the terms hereof and thereof, together with such powers and discretion as are reasonably
incidental thereto. As to any matters not expressly provided for by this Agreement (including,
without limitation, enforcement or collection of the Notes, if any), the Administrative Agent shall
not be required to exercise any discretion or take any action, but shall be required to act or to
refrain from acting (and shall be fully protected in so acting or refraining from acting) upon the
instructions of the Majority Banks, and such instructions shall be binding upon all Banks and all
holders of Notes (if any); provided, however, that the Administrative Agent shall
not be required to take any action that exposes the Administrative Agent to personal liability or
that is contrary to this Agreement or applicable law. The Administrative Agent agrees to give to
each Bank prompt notice of each notice given to it by the Borrower pursuant to the terms of this
Agreement.

          SECTION
9.2. Administrative Agent’s Reliance, Etc. Neither the Administrative Agent nor any of its
directors, officers, agents or employees shall be liable for any action taken or omitted to be
taken by it or them under or in connection with this Agreement, except to the extent that any of
the foregoing are found by a final and non-appealable decision of a court of competent jurisdiction
to have resulted from its or their own gross negligence or willful misconduct. Without limitation
of the generality of the foregoing, the Administrative Agent: (i) may consult with legal counsel
(including counsel for the Borrower), independent public accountants and other experts selected by
it and shall not be liable for any action taken or omitted to be taken in good faith by it in
accordance with the advice of such counsel, accountants or experts; (ii) makes no warranty or
representation to any Bank and shall not be responsible to any Bank for any statements, warranties
or representations (whether written or oral) made in or in connection with this Agreement; (iii)
shall not have any duty to ascertain or to inquire as to the performance, observance or
satisfaction of any of the terms, covenants or conditions of this Agreement on the part of the
Borrower or the existence at any time of any Default or to inspect the property (including the
books and records) of the Borrower; (iv) shall not be responsible to any Bank for the due
execution, legality, validity, enforceability, genuineness, sufficiency or value of, or, if
applicable, the perfection or priority of any lien or security interest created or purported to be
created under or in connection with, this Agreement or any other instrument or document furnished
pursuant hereto; and (v) shall incur no liability under or in respect of this

70

 

Agreement by acting
upon any notice, consent, certificate or other instrument or writing (which may be by telecopier,
telegram or electronic communication) believed by it to be genuine and signed or sent by the proper
party or parties.

     SECTION
9.3. Bank Credit Decision Each Bank acknowledges that it has, independently and without
reliance upon the Administrative Agent, any Lead Arranger or any other Bank and based on the
financial statements referred to in Section 6.1 and such other documents and information as it has
deemed appropriate, made its own credit analysis and decision to enter into this Agreement. Each
Bank also acknowledges that it will, independently and without reliance upon the Administrative
Agent, any Lead Arranger or any other Bank and based on such documents and information as it shall
deem appropriate at the time, continue to make its own credit decisions in taking or not taking
action under this Agreement.

     SECTION
9.4. Indemnification  The Banks agree to indemnify the Administrative Agent and each
Lead Arranger (to the extent not reimbursed by the Borrower), ratably according to the respective
principal amounts of the Notes (if any) then held by each of them (or if no Notes are at the time
outstanding or if any Notes are held by Persons that are not Banks, ratably according to the
respective amounts of their Commitments), from and against any and all liabilities, obligations,
losses, damages, penalties, actions, judgments, suits, costs, expenses or disbursements of any kind
or nature whatsoever that may be imposed on, incurred by, or asserted against the Administrative
Agent and/or any Lead Arranger in any way relating to or arising out of this Agreement or any
action taken or omitted by the Administrative Agent or any Lead Arranger under this Agreement
(collectively, the “Indemnified Costs”), provided that no Bank shall be liable for
any portion of the Indemnified Costs that are found to by a final and non-appealable decision of a
court of competent jurisdiction to have resulted from the Administrative Agent’s and/or any Lead
Arranger’s gross negligence or willful misconduct. Without limitation of the foregoing, each Bank
agrees to reimburse the Administrative Agent promptly upon demand for its ratable share of any out
of pocket expenses (including counsel fees) incurred by the Administrative Agent in connection with
the preparation, execution, delivery, administration, modification, amendment or enforcement
(whether through negotiations, legal proceedings or otherwise) of, or legal advice in respect of
rights or responsibilities under, this Agreement, to the extent that the Administrative Agent is
not reimbursed for such expenses by the Borrower. In the case of any investigation, litigation or
proceeding giving rise to any Indemnified Costs, this Section 9.4 applies whether any such
investigation, litigation or proceeding is brought by the Administrative Agent, any Bank or a third
party.

     (b) Each Bank severally agrees to indemnify each Issuing Bank (to the extent not promptly
reimbursed by the Borrower) from and against such Bank’s ratable share (determined as provided
below) of any and all liabilities, obligations, losses, damages, penalties, actions, judgments,
suits, costs, expenses or disbursements of any kind or nature whatsoever that may be imposed on,
incurred by, or asserted against such Issuing Bank in any way relating to or arising out of the
Loan Documents or any action taken or omitted by such Issuing Bank under the Loan Documents;
provided, however, that no Bank shall be liable for any portion of such
liabilities, obligations, losses, damages, penalties, actions, judgments, suits, costs, expenses or
disbursements resulting from such Issuing Bank’s gross negligence or willful misconduct as found in
a final, non-appealable judgment by a court of competent jurisdiction. Without limitation of the
foregoing, each Bank agrees to reimburse such Issuing Bank promptly upon

71

 

demand for its ratable share of any costs and expenses (including, without limitation, fees
and expenses of counsel) payable by the Borrower under Section 10.5, to the extent that such
Issuing Bank is not promptly reimbursed for such costs and expenses by the Borrower.

     (c) For purposes of this Section 9.4, each Bank’s ratable share of any amount shall be
determined, at any time, according to the sum of (i) such Bank’s Outstanding Extensions of Credit
and (ii) such Bank’s Available Commitment in accordance with its applicable Revolving Percentage at
such time; provided that the aggregate principal amount of drawings under Letters of Credit
that have not been reimbursed to any Issuing Bank shall be considered to be owed to the Banks
ratably in accordance with their respective Revolving Percentages. The failure of any Bank to
reimburse any Agent or any Issuing Bank, as the case may be, promptly upon demand for its ratable
share of any amount required to be paid by the Banks to such Agent or such Issuing Bank, as the
case may be, as provided herein shall not relieve any other Bank of its obligation hereunder to
reimburse such Agent or such Issuing Bank, as the case may be, for its ratable share of such
amount, but no Bank shall be responsible for the failure of any other Bank to reimburse such Agent
or such Issuing Bank, as the case may be, for such other Bank’s ratable share of such amount.
Without prejudice to the survival of any other agreement of any Bank hereunder, the agreement and
obligations of each Bank contained in this Section 9.4 shall survive the payment in full of
principal, interest and all other amounts payable hereunder and under the other Loan Documents.

     SECTION
9.5. Citibank, N.A, and Affiliates With respect to its Commitment, the Loans made by it and
the Note, if any, issued to it, Citibank, N.A. shall have the same rights and powers under this
Agreement as any other Bank and may exercise the same as though it were not the Administrative
Agent; and the term “Bank” or “Banks” shall, unless otherwise expressly indicated, include
Citibank, N.A. in its respective individual capacities. Citibank, N.A. and its respective
Affiliates may accept deposits from, lend money to, act as trustee under indentures of, accept
investment banking engagements from and generally engage in any kind of business with, the
Borrower, any of its Subsidiaries and any Person who may do business with or own securities of the
Borrower or any such Subsidiary, all as if Citibank, N.A. was not the Administrative Agent and
without any duty to account therefor to the Banks. The Administrative Agent shall have no duty to
disclose any information obtained or received by it or any of its Affiliates relating to the
Borrower or any of its Subsidiaries to the extent such information was obtained or received in any
capacity other than as the Administrative Agent.

     SECTION
9.6. Successor Administrative Agent The Administrative Agent may resign as Administrative
Agent upon 10 days’ notice to the Banks and the Borrower. Upon any such resignation, the Majority
Banks shall have the right to appoint a successor Administrative Agent, which successor
Administrative Agent shall (unless an Event of Default under Sections 8.1(a), (g) or (h) with
respect to the Borrower shall have occurred and be continuing) be subject to approval by the
Borrower (which approval shall not be unreasonably withheld or delayed). If no successor
Administrative Agent shall have
been so appointed by the Majority Banks, and shall have accepted such appointment, within 15
days after the resigning Administrative Agent’s giving of notice of resignation, then the resigning
Administrative Agent may, on behalf of the Banks, appoint a successor Administrative Agent, which
shall be a financial institution engaged

72

 

or licensed to conduct banking business under the laws of
the United States of America or of any State thereof and having a combined capital and surplus of
at least $500,000,000; provided that if the Administrative Agent shall notify the Borrower
and the Banks that no qualifying Person has accepted such appointment, then such resignation shall
nonetheless become effective in accordance with such notice and (1) the resigning Administrative
Agent shall be discharged from its duties and obligations hereunder and (2) all payments,
communications and determinations provided to be made by, to or through the Administrative Agent
shall instead be made by or to each Bank and Issuing Bank directly, until such time as the Majority
Banks appoint a successor Administrative Agent as provided for above in this paragraph (with the
consent of the Borrower to the extent required above). Upon the acceptance of any appointment as
Administrative Agent hereunder by a successor Administrative Agent, such successor Administrative
Agent shall thereupon succeed to and become vested with all the rights, powers, discretion,
privileges and duties of the resigning Administrative Agent, and the resigning Administrative Agent
shall be discharged from its duties and obligations under this Agreement. After any resigning
Administrative Agent’s resignation hereunder as Administrative Agent, the provisions of this
Article IX and of Section 10.5 shall continue to inure to its benefit as to any actions taken or
omitted to be taken by it while it was Administrative Agent under this Agreement.

     SECTION 9.7. Co-Syndication Agents, Co-Documentation Agents, Lead Arrangers, and Global
Coordinators Notwithstanding anything to the contrary contained herein, no Bank identified as a
“Co-Syndication Agent”, “Co-Documentation Agent”, “Lead Arranger” or “Global Coordinator” shall
have the right, power, obligation, liability, responsibility or duty under this Agreement or any
other Loan Document other than those applicable to all Banks as such. Without limiting the
foregoing, none of the Banks so identified shall have or be deemed to have any fiduciary
relationship with any Bank. Each Bank acknowledges that it has not relied, and will not rely, on
any of the Banks so identified in deciding to enter into this Agreement or not taking action
hereunder.

ARTICLE X

provided that any notice, request or demand to or upon the Administrative Agent or the
Banks shall not be effective until received during such recipient’s normal business hours.

     (b) The Borrower hereby acknowledges that (i) certain of the Lenders may be “public-side”
Lenders (i.e., Lenders that do not wish to receive material non-public information with respect to
the Borrower or its securities) (each, a “Public Lender”) and (ii) the Administrative Agent
will make available to the Lenders certain notices, requests, financial statements, financial and
other reports, certificates and other information materials, but excluding any such communication
that initiates or responds to the legal process (all such non-excluded information being referred
to herein collectively as the “Communications”) on IntraLinks or another relevant website
(whether a commercial, third-party website or whether sponsored by the Administrative Agent) (the
“Platform”). The Borrower hereby agrees that all Communications that are to be made
available to Public Lenders shall be clearly and conspicuously marked “PUBLIC” which, at a minimum,
shall mean that the word “PUBLIC” shall appear prominently on the first page thereof, (ii) by
marking Communications “PUBLIC,” the Borrower shall be deemed to have authorized the Administrative
Agent, the Issuing Banks and the Lenders to treat such Communications as not containing any
material non-public information with respect to the Borrower or its securities for purposes of
United States Federal and state securities laws, it being understood that certain of such
Communications may be subject to the confidentiality requirements hereof, (iii) all Communications
marked “PUBLIC” are permitted to be made available through a portion of the Platform designated
“Public Investor,” and (iv) the Administrative Agent shall be entitled to treat any Communications
that are not marked “PUBLIC” as being suitable only for posting on a portion of the Platform not
designated “Public Investor.” Notwithstanding the foregoing, (A) the Borrower shall be under no
obligation to mark any Communications “PUBLIC,” and each Public Lender hereby waives its right to
receive any Communications that are not marked “PUBLIC”; and (B) the Administrative Agent shall
treat Communications that are deemed to have been delivered based on notice pursuant to the last
sentence of Section 7.1(a) as “PUBLIC.”

     (c) Each Bank agrees that e-mail notice to it (at the address provided pursuant to the
next sentence and deemed delivered as provided in the next paragraph) specifying that
Communications have been posted to the Platform shall constitute effective delivery of such
Communications to such Bank for purposes of this Agreement. Each Bank agrees (i) to notify the
Administrative Agent in writing (including by electronic communication) from time to time to ensure
that the Administrative Agent has on record an effective e-mail address for such Bank to which the
foregoing notice may be sent by electronic transmission and (ii) that the foregoing notice may be
sent to such e-mail address.

     (d) Each party hereto agrees that any electronic communication referred to in this Section
10.2 shall be deemed delivered upon the posting of a record of such communication (properly
addressed to such party at the e-mail address provided to the Administrative Agent) as “received”
in the e-mail system of such party; provided that if such communication is not so received
by such party during the normal business hours of such party, such communication shall be deemed
delivered at the opening of business on the next Business Day for such party.

76

 

     (e) Each party hereto acknowledges that (i) the distribution of material through an
electronic medium is not necessarily secure and there are confidentiality and other risks
associated with such distribution, (ii) the Communications and the Platform are provided “as is”
and “as available,” (iii) none of the Administrative Agent, its affiliates nor any of their
respective officers, directors, employees, agents, advisors or representatives (collectively, the
“Citigroup Parties”) warrants the adequacy of the Platform or the accuracy or completeness
of any Communications, and each Citigroup Party expressly disclaims liability for errors or
omissions in any Communications or the Platform, and (iv) no warranty of any kind, express, implied
or statutory, including, without limitation, any warranty of merchantability, fitness for a
particular purpose, non-infringement of third party rights or freedom from viruses or other code
defects, is made by any Citigroup Party in connection with any Communications or the Platform.

     (f) The Administrative Agent or the Borrower may, in its discretion, agree to accept
notices and other communications pursuant to procedures approved by it; provided that
approval of such procedures may be limited to particular notices or circumstances.

     (g) Any party hereto may change its address, facsimile number or electronic mail address
for notices and other communications hereunder by notice to the other parties hereto.

     SECTION
10.3. No Waiver; Cumulative Remedies. No failure to exercise and no delay in exercising, on
the part of the Administrative Agent or any Bank, any right, remedy, power or privilege hereunder
shall operate as a waiver thereof, nor shall any single or partial exercise of any right, remedy,
power or privilege hereunder preclude any other or further exercise thereof or the exercise of any
other right, remedy, power or privilege. The rights, remedies, powers and privileges herein
provided are cumulative and not exclusive of any rights, remedies, powers and privileges provided
by law.

     SECTION 10.4. Survival of Representations and Warranties. All representations and warranties made
hereunder and in any document, certificate or statement delivered pursuant hereto or in connection
herewith shall survive the execution and delivery of this Agreement.

     SECTION 10.5. Payment of Expenses; Indemnity. (a) The Borrower agrees (i) to pay all reasonable
out-of-pocket expenses of the Global Coordinators associated with the syndication of the Facility,
(ii) to pay or reimburse the Administrative Agent for all its reasonable out-of-pocket costs and
expenses incurred in connection with the preparation, negotiation and execution and delivery of,
and any amendment, supplement or modification to, this Agreement and the other Loan Documents and
any other
documents prepared in connection herewith or therewith, and the consummation and
administration of the transactions contemplated hereby and thereby, including the reasonable fees
and disbursements of Simpson Thacher & Bartlett LLP, counsel to the Administrative Agent (but
excluding the fees or expenses of any other counsel), (iii) to pay or reimburse the Administrative
Agent for all its costs and expenses incurred in connection with the enforcement or preservation of
its rights under this Agreement, the other Loan Documents and any other documents prepared in
connection herewith or therewith, including the reasonable fees and disbursements of the special
counsel to the Administrative Agent, (iv) to pay or reimburse each Bank for all its costs and
expenses incurred in connection with the enforcement, or at any time after the occurrence and
during the continuance of a Default or an Event of Default, the preservation, of its rights under
this Agreement, the other Loan Documents and any

77

 

other documents prepared in connection herewith or
therewith, including (A) the reasonable fees and disbursements of counsel to such Bank and (B)
other out-of-pocket expenses incurred during any workout, restructuring or negotiations in respect
of such Loans or Letters of Credit, (v) without duplication of any other provision contained in
this Agreement or any Notes, to pay, indemnify, and hold each Bank and the Administrative Agent
harmless from, any and all recording and filing fees (for which each Bank has not been otherwise
reimbursed by the Borrower under this Agreement), if any, that may be payable or determined to be
payable in connection with the execution and delivery of, or consummation or administration of any
of the transactions contemplated by, or any amendment, supplement or modification of, or any waiver
or consent under or in respect of, this Agreement, the other Loan Documents and any other documents
prepared in connection herewith or therewith, and (vi) without duplication of any other provision
contained in this Agreement or any Notes, to pay, indemnify and hold the Administrative Agent, each
Global Coordinator, each Lead Arranger, each Bank, each Issuing Bank, each Swingline Lender and
each Agent together with their respective directors, officers, employees, agents, trustees,
advisors and Affiliates (collectively, the “Indemnified Persons”), harmless from and
against, any and all losses, claims, damages and liabilities (and shall reimburse each Indemnified
Person upon demand for any reasonable legal or other expenses incurred by such Indemnified Person
in connection with investigating or defending any of the foregoing), incurred by any Indemnified
Person arising out of, in connection with, or as a result of the execution, delivery, enforcement,
performance and administration of this Agreement and the other Loan Documents, the transactions
contemplated by this Agreement and the other Loan Documents, or the use, or proposed use, of
proceeds of the Loans (all the foregoing in this clause (vi), collectively, the “Indemnified
Liabilities”); provided that the Borrower shall have no obligation hereunder to an
Indemnified Person with respect to Indemnified Liabilities arising from or in connection with (A)
the gross negligence or willful misconduct of such Indemnified Person or (B) the material breach by
such Indemnified Person of the express terms of this Agreement, in the case of each of the
foregoing clauses (A) and (B) as determined by a final, non-appealable judgment of a court of
competent jurisdiction, AND PROVIDED FURTHER THAT, SUBJECT TO THE LIMITATIONS DESCRIBED HEREIN, IT
IS THE INTENTION OF THE BORROWER TO INDEMNIFY THE INDEMNIFIED PERSONS AGAINST THE CONSEQUENCES OF
THEIR OWN NEGLIGENCE.

     (b) Each party hereto hereby waives, to the maximum extent permitted by applicable law,
any right it may have to claim or recover from any other party hereto any special, indirect,
punitive or consequential damages (as opposed to direct or actual damages) arising out of, in
connection with, or as a result of the execution, delivery, enforcement, performance and
administration of this Agreement and the other Loan Documents, the transactions contemplated
by this Agreement and the other Loan Documents, or the use, or proposed use, of proceeds of the
Loans; provided that nothing contained in this paragraph (b) shall limit the Borrower’s
indemnification provisions contained in paragraph (a) above.

     (c) In the case of an investigation, litigation or other proceeding to which the indemnity
in this Section 10.5 applies, such indemnity shall be effective whether or not such investigation,
litigation or proceeding is brought by the Borrower, any of the Borrower’s directors, security
holders, affiliates, creditors, an Indemnified Person or any other Person, whether or not an
Indemnified Person is otherwise a party to this Agreement.

78

 

     (d) The agreements in this Section 10.5 shall survive repayment of the Loans and all other
amounts payable hereunder and termination of this Agreement.

     SECTION 10.6. Effectiveness, Successors and Assigns; Participations; Assignments. (a) This
Agreement shall become effective on the date hereof and thereafter shall be binding upon and inure
to the benefit of the Borrower, the Banks, each Issuing Bank, the Administrative Agent, all future
holders of the Loans and their respective successors and assigns, except that the Borrower may not
assign or transfer any of its rights or obligations under this Agreement without the prior written
consent of each Bank.

     (b) Any Bank may, without the consent of the Borrower or the Administrative Agent, in the
ordinary course of its business and in accordance with applicable law, at any time sell to one or
more banks or other financial institutions or Bank Affiliates (a “Participant”)
participating interests in any Loan owing to such Bank, any Note held by such Bank, any Commitment
of such Bank or any other interest of such Bank hereunder and under the other Loan Documents. In
the event of any such sale by a Bank of a participating interest to a Participant, such Bank’s
obligations under this Agreement to the other parties to this Agreement shall remain unchanged,
such Bank shall remain solely responsible for the performance thereof, such Bank shall remain the
holder of any such Loan and Commitment or other interest for all purposes under this Agreement and
the other Loan Documents, the Borrower and the Administrative Agent shall continue to deal solely
and directly with such Bank in connection with such Bank’s rights and obligations under this
Agreement and the other Loan Documents and, except with respect to the matters set forth in Section
10.1, the amendment of which requires the consent of all of the Banks, the participation agreement
between the selling Bank and the Participant may not restrict such Bank’s voting rights hereunder.
The Borrower agrees that each Participant shall be entitled to the benefits of Sections 4.1 and 4.3
(subject to the requirements and limitations therein, including the requirements under Section
4.3(e) and Section 4.3(f) (it being understood that the documentation required under Section 4.3(e)
and Section 4.3(f) shall be delivered to the participating Bank)) to the same extent as if it were
a Bank and had acquired its interest by assignment pursuant to paragraph (c) of this Section;
provided that such Participant (i) agrees to be subject to the provisions of Sections 4.1
and 4.3 as if it were an assignee under paragraph (c) of this Section and (ii) shall not be
entitled to receive any greater payment under Sections 4.1 or 4.3, with respect to any
participation, than its participating Bank would have been entitled to receive, except to the
extent such entitlement to receive a greater payment results from an adoption of or any change in
any Requirement of Law or in the interpretation or application
thereof or compliance by any Bank with any request or directive (whether or not having the
force of law) from any central bank or other Governmental Authority made subsequent to the date
hereof that occurs after the Participant acquired the applicable participation. The Borrower
further agrees that each Participant, to the extent provided in its participation, shall be
entitled to the benefits of Sections 3.4 and 3.7 with respect to its participation in the
Commitments and the Loans outstanding from time to time; provided that (i) no Participant
shall be entitled to receive any greater amount pursuant to such Sections than the selling Bank
would have been entitled to receive in respect of the amount of the participation sold by such
selling Bank to such Participant had no such sale occurred and (ii) each such sale of participating
interests shall be to a “qualified purchaser”, as such term is defined under the Investment Company
Act of 1940, as amended. Except as expressly provided in this Section 10.6(b), no Participant
shall be a third-party beneficiary of or have any rights under this Agreement or under any of the
other Loan

79

 

Documents. Each Bank that sells a participation, acting solely for this purpose as an
agent of the Borrower, shall maintain a register on which it enters the name and address of each
Participant and the principal amounts (and stated interest) of each Participant’s interest in the
Loans or other obligations under this Agreement (the “Participant Register”);
provided that no Bank shall have any obligation to disclose all or any portion of the
Participant Register to any Person (including the identity of any Participant or any information
relating to a Participant’s interest in any Commitments, Loans, Letters of Credit or its other
obligations under any Loan Document) except to the extent that such disclosure is necessary to
establish that such Commitment, Loan, Letter of Credit or other obligation is in registered form
under Section 5f.103-1(c) of the United States Treasury Regulations. The entries in the Participant
Register shall be conclusive, and such Bank, each of the Borrower or any of its Subsidiaries that
is a party to any Loan Document, and the Administrative Agent shall treat each person whose name is
recorded in the Participant Register pursuant to the terms hereof as the owner of such
participation for all purposes of this Agreement, notwithstanding notice to the contrary.

     (c) Except as set forth below, the Banks shall be permitted to assign all or a portion of
their Loans and Commitments to one or more financial institutions (“Purchasing Banks”) with
the consent, not to be unreasonably withheld, of (a) the Borrower (provided that the Borrower shall
be deemed to have consented to such assignment unless it shall have notified the Administrative
Agent of its refusal to give such consent within 10 Business Days following the Borrower’s receipt
from the transferor Bank of a fully-completed Assignment and Acceptance (as defined below) with
respect to such assignment, delivered in accordance with Section 10.2), unless (i) the Purchasing
Bank is a Bank or a Bank Affiliate or (ii) an Event of Default has occurred and is continuing, (b)
the Administrative Agent, unless the assignment is from a Bank to its Bank Affiliate, and (c) each
Issuing Bank, unless the assignment is from a Bank to its Bank Affiliate, pursuant to an Assignment
and Acceptance, substantially in the form of Exhibit C (an “Assignment and
Acceptance”), executed by such Purchasing Bank and such transferor Bank (and by the Borrower,
the Administrative Agent and each Issuing Bank, as applicable) and delivered to the Administrative
Agent for its acceptance and recording in the Register; provided that (i) such Purchasing
Bank is a “qualified purchaser” as defined under the Investment Company Act of 1940, as amended,
(ii) each such sale shall be of a uniform, and not a varying, percentage of all rights and
obligations under and in respect of the Commitment of such Bank, (iii) each such sale shall be in
an aggregate amount of not less than $5,000,000 (or such lesser amount representing the entire
Commitment of such transferor Bank) if such sale is not to an existing Bank and (iv) after giving
effect to such sale, the transferor Bank shall (to the extent that
it continues to have any Commitment hereunder) have a Commitment of not less than $5,000,000,
provided that such amounts shall be aggregated in respect of each Bank and its Bank
Affiliates, if any. Upon such execution, delivery, acceptance and recording, from and after the
effective date determined pursuant to such Assignment and Acceptance (the “Transfer Effective
Date”), (i) the Purchasing Bank thereunder shall be a party hereto and, to the extent provided
in such Assignment and Acceptance, have the rights and obligations of a Bank hereunder with the
Commitments as set forth therein and (ii) the transferor Bank thereunder shall, to the extent
provided in such Assignment and Acceptance, be released from its obligations under this Agreement
(and, in the case of an Assignment and Acceptance covering all or the remaining portion of a
transferor Bank’s rights and obligations under this Agreement, such transferor Bank shall cease to
be a party hereto). Such Assignment and Acceptance shall be deemed to amend this Agreement to the
extent, and only to the extent, necessary to reflect the addition of such

80

 

Purchasing Bank and the
resulting adjustment of Revolving Percentages arising from the purchase by such
Purchasing Bank of
all or a portion of the rights and obligations of such transferor Bank under this Agreement. On or
prior to the Transfer Effective Date determined pursuant to such Assignment and Acceptance, (i)
appropriate entries shall be made in the accounts of the transferor Bank and the Register
evidencing such assignment and releasing the Borrower from any and all obligations to the
transferor Bank in respect of the assigned Loan or Loans and (ii) appropriate entries evidencing
the assigned Loan or Loans shall be made in the accounts of the Purchasing Bank and the Register as
required by Section 3.1 hereof. In the event that any Notes have been issued in respect of the
assigned Loan or Loans, such Notes shall be marked “cancelled” and surrendered by the transferor
Bank to the Administrative Agent for return to the Borrower.

     (d) The Administrative Agent shall maintain at its address referred to in Section 10.2(a)
a copy of each Assignment and Acceptance delivered to it and a register (the “Register”)
for the recordation of the names and addresses of the Banks and the Commitments of, and principal
amount of the Loans owing to, each Bank from time to time. To the extent permitted by applicable
law, the entries in the Register shall be conclusive, in the absence of manifest error, and the
Borrower, the Administrative Agent and the Banks may (and, in the case of any Loan or other
obligations hereunder not evidenced by a Note, shall) treat, each Person whose name is recorded in
the Register pursuant to the terms hereof as the owner of a Loan or other obligation hereunder as
the owner thereof for all purposes of this Agreement and the other Loan Documents, notwithstanding
any notice to the contrary. Any assignment of any Loan or other obligation hereunder shall be
effective only upon appropriate entries with respect thereto being made in the Register. The
Register shall be available for inspection by the Borrower or any Bank at any reasonable time and
from time to time upon reasonable prior notice.

     (e) Upon its receipt of an Assignment and Acceptance executed by a transferor Bank and
Purchasing Bank (and, in the case of a Purchasing Bank that is not then a Bank Affiliate, by the
Borrower and the Administrative Agent), together with payment to the Administrative Agent of a
registration and processing fee of $3,500, the Administrative Agent shall promptly accept such
Assignment and Acceptance on the Transfer Effective Date determined pursuant thereto, record the
information contained therein in the Register and give notice of such acceptance and recordation to
the Banks and the Borrower.

     (f) Any Bank 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 Bank, including any pledge or
assignment to secure obligations to a Federal Reserve Bank or other central banking authority, 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 Bank from
any of its obligations hereunder or substitute any such pledgee or Purchasing Bank for such Bank as
a party hereto. The Borrower hereby agrees that, upon request of any Bank at any time and from
time to time after the Borrower has made its initial Borrowing hereunder, the Borrower shall
provide to such Bank, at the Borrower’s own expense, a promissory note, substantially in the form
of Exhibit D-1 or D-2 evidencing the Loans or L/C Obligations, as the case may be, owing to
such Bank.

81

 

    SECTION 10.7. Setoff. In addition to any rights and remedies of the Banks provided by law, if any
Event of Default shall have occurred and be continuing, each Bank shall have the right, to the
fullest extent permitted by law, without prior notice to the Borrower (any such notice being
expressly waived by the Borrower to the extent permitted by applicable law), to set off and apply
any and all deposits (general or special, time or demand, provisional or final), in any currency,
and any other credits, indebtedness or claims, in any currency, in each case whether direct or
indirect, absolute or contingent, matured or unmatured, at any time held or owing by such Bank or
any branch or agency thereof to or for the credit or the account of the Borrower against any of and
all the obligations of the Borrower existing under this Agreement which are then due and payable.
Each Bank agrees promptly to notify the Borrower and the Administrative Agent after any such setoff
and application made by such Bank, provided that the failure to give such notice shall not
affect the validity of such setoff and application.

     SECTION 10.8. Counterparts. This Agreement may be executed by one or more of the parties to this
Agreement on any number of separate counterparts, and all of said counterparts taken together shall
be deemed to constitute one and the same instrument. A set of the copies of this Agreement signed
by all the parties shall be maintained with Borrower and the Administrative Agent.

     SECTION 10.9. Severability. Any provision of this Agreement that is prohibited or unenforceable in
any jurisdiction shall, as to such jurisdiction, be ineffective to the extent of such prohibition
or unenforceability without invalidating the remaining provisions hereof, and any such prohibition
or unenforceability in any jurisdiction shall not invalidate or render unenforceable such provision
in any other jurisdiction.

     SECTION 10.10. Integration. This Agreement and the other Loan Documents represent the agreement of
the Borrower, the Administrative Agent and the Banks with respect to the subject matter hereof, and
there are no promises, undertakings, representations or warranties by the Administrative Agent
or any Bank relative to the subject matter hereof not expressly set forth or referred to
herein or in the other Loan Documents.

     SECTION 10.11. GOVERNING LAW. (a) THIS AGREEMENT AND THE OTHER LOAN DOCUMENTS SHALL BE GOVERNED BY,
AND CONSTRUED AND INTERPRETED IN ACCORDANCE WITH, THE LAWS OF THE STATE OF NEW YORK.

     (b) Notwithstanding anything in Section 10.11(a) to the contrary, nothing in this
Agreement or in any Note or any other Loan Documents shall be deemed to constitute a waiver of any
rights which any Bank may have under applicable federal law relating to the amount of interest
which any Bank may contract for, take, receive or charge in respect of any Loans, including any
right to take, receive, reserve and charge interest at the rate allowed by the laws of the state
where such Bank is located. To the extent that Texas law is applicable to the determination of the
Highest Lawful Rate, the Banks and the Borrower agree that (i) if Chapter 303 of the Texas Finance
Code, as amended, is applicable to such determination, the weekly rate ceiling as computed from
time to time shall apply, provided that, to the extent permitted by such Article, the
Administrative Agent may from time to time by notice to the Borrower revise the election of such
interest rate ceiling as such ceiling affects the then current

82

 

or future balances of the Loans; and
(ii) the provisions of Chapter 346 of the Texas Finance Code, as amended shall not apply to this
Agreement or any Note issued hereunder.

     SECTION 10.12. Submission to Jurisdiction; Waivers. The Borrower hereby irrevocably and
unconditionally:

     (a) submits for itself and its property in any legal action or proceeding relating to this
Agreement and the other Loan Documents to which it is a party, or for recognition and enforcement
of any judgment in respect thereof, to the non-exclusive general jurisdiction of the Courts of the
State of New York sitting in New York County, the courts of the United States of America for the
Southern District of New York, and appellate courts from any thereof;

     (b) consents that any such action or proceeding may be brought in such courts and waives
any objection that it may now or hereafter have to the venue of any such action or proceeding in
any such court or that such action or proceeding was brought in an inconvenient court and agrees
not to plead or claim the same;

     (c) agrees that service of process in any such action or proceeding may be effected by
mailing a copy thereof by registered or certified mail (or any substantially similar form of mail),
postage prepaid to the Borrower at its address set forth in Section 10.2 or at such other address
of which the Administrative Agent shall have been notified pursuant thereto; and

     (d) agrees that nothing herein shall affect the right to effect service of process in any
other manner permitted by law or shall limit the right to sue in any other jurisdiction.

     SECTION 10.13. Acknowledgments. The Borrower hereby acknowledges that:

     (a) it has been advised by counsel in the negotiation, execution and delivery of this
Agreement and the other Loan Documents;

     (b) neither the Administrative Agent nor any Bank has any fiduciary relationship with or
duty to the Borrower arising out of or in connection with this Agreement or any of the other Loan
Documents, and the relationship between the Administrative Agent and the Banks, on one hand, and
the Borrower, on the other hand, in connection herewith or therewith is solely that of debtor and
creditor; and

     (c) no joint venture exists among the Banks or among the Borrower and the Banks.

     SECTION 10.14. Limitation on Agreements. All agreements between the Borrower, the Administrative
Agent or any Bank, whether now existing or hereafter arising and whether written or oral, are
hereby expressly limited so that in no contingency or event whatsoever, whether by reason of demand
being made in respect of an amount due under any Loan Document or otherwise, shall the amount paid,
or agreed to be paid, to the Administrative Agent or any Bank for the use, forbearance, or
detention of the money to be loaned under this Agreement, any Notes or any other Loan Document or
otherwise or for the payment or performance of any covenant or obligation contained herein or in
any other Loan Document exceed the Highest Lawful Rate. If, as a result of any circumstances
whatsoever, fulfillment of any provision hereof or of any of such documents, at the time
performance of such provision shall be due, shall

83

 

involve transcending the limit of validity
prescribed by applicable usury law, then, ipso facto, the obligation to be fulfilled shall be
reduced to the limit of such validity, and if, from any such circumstance, the Administrative Agent
or any Bank shall ever receive interest or anything that might be deemed interest under applicable
law that would exceed the Highest Lawful Rate, such amount that would be excessive interest shall
be applied to the reduction of the principal amount owing on account of such Bank’s Loans or the
amounts owing on other obligations of the Borrower to the Administrative Agent or any Bank under
any Loan Document and not to the payment of interest, or if such excessive interest exceeds the
unpaid principal balance of such Bank’s Loans and the amounts owing on other obligations of the
Borrower to the Administrative Agent or any Bank under any Loan Document, as the case may be, such
excess shall be refunded to the Borrower. All sums paid or agreed to be paid to the Administrative
Agent or any Bank for the use, forbearance or detention of the indebtedness of the Borrower to the
Administrative Agent or any Bank shall, to the fullest extent permitted by applicable law, be
amortized, prorated, allocated and spread throughout the full term of such indebtedness until
payment in full of the principal (including the period of any renewal or extension thereof) so that
the interest on account of such indebtedness shall not exceed the Highest Lawful Rate.
Notwithstanding anything to the contrary contained in any Loan Document, it is understood and
agreed that if at any time the rate of interest that accrues on the outstanding principal balance
of any Loan shall exceed the Highest Lawful Rate, the rate of interest that accrues on the
outstanding principal balance of any Loan shall be limited to the Highest Lawful Rate, but any
subsequent reductions in the rate of interest that accrues on the outstanding principal balance of
any Loan shall not reduce the rate of interest that accrues on the outstanding principal balance of
any Loan below the Highest Lawful Rate until the total
amount of interest accrued on the outstanding principal balance of any Loan equals the amount
of interest that would have accrued if such interest rate had at all times been in effect. The
terms and provisions of this Section 10.14 shall control and supersede every other provision of all
Loan Documents.

          SECTION 10.15. Removal of Bank. Notwithstanding anything herein or in any other Loan Document to the
contrary, the Borrower may, at any time in its sole discretion, remove any Bank upon 15 Business
Days’ written notice to such Bank and the Administrative Agent (the contents of which notice shall
be promptly communicated by the Administrative Agent to each other Bank), such removal to be
effective at the expiration of such 15-day notice period; provided, however, that
no Bank may be removed hereunder at a time when an Event of Default shall have occurred and be
continuing. Each notice by the Borrower under this Section 10.15 shall constitute a representation
by the Borrower that the removal described in such notice is permitted under this Section 10.15.
Concurrently with such removal, the Borrower shall pay to such removed Bank all amounts owing to
such Bank hereunder (including any amounts arising under Section 3.7 as a consequence of such
removal) and under any other Loan Document in immediately available funds. Upon full and final
payment hereunder of all amounts owing to such removed Bank, such Bank shall make appropriate
entries in its accounts evidencing payment of all Loans hereunder and releasing the Borrower from
all obligations owing to the removed Bank in respect of the Loans hereunder and surrender to the
Administrative Agent for return to the Borrower any Notes of the Borrower then held by it.
Effective immediately upon such full and final payment, such removed Bank will not be considered to
be a “Bank” for purposes of this Agreement, except for the purposes of any provision hereof that by
its terms survives the termination of this Agreement and the payment of the amounts payable
hereunder. Effective immediately upon such removal, the Commitment of such removed Bank shall

84

 

immediately terminate and such Bank’s participation share in any outstanding Letters of Credit
shall immediately terminate and such participation share shall be divided among the remaining Banks
according to their Revolving Percentages. Such removal will not, however, affect the Commitments
of any other Banks hereunder.

     SECTION 10.16. Confidentiality. Each of the Banks and the Administrative Agent agrees to maintain,
and to use its commercially reasonable efforts to cause any third party recipient of the
information described in this Section 10.16 to maintain, any information delivered or made
available by the Borrower to it (including any information obtained pursuant to Section 7.1),
confidential from anyone other than Persons employed or retained by such party who are or are
expected to become engaged in evaluating, approving, structuring or administering the transactions
contemplated hereunder; provided that nothing shall prevent any Bank or the Administrative Agent
from disclosing such information (i) to any other Bank or any Affiliate of any Bank, (ii) pursuant
to subpoena or upon the order of any court or administrative agency having jurisdiction over such
Bank or the Administrative Agent, as the case may be, (iii) upon the request or demand of any
Governmental Authority or self-regulatory body, in each case, having jurisdiction over such Bank or
the Administrative Agent, as the case may be, (iv) if such information has been publicly disclosed
(other than by reason of disclosure by any Bank or the Administrative
Agent in breach of its obligations under this Section 10.16), (v) to the extent reasonably
required in connection with any litigation to which either the Administrative Agent, any Bank, the
Borrower or their respective Affiliates may be a party relating to this Agreement or any other Loan
Document, (vi) to the extent reasonably required in connection with the exercise of any remedy
hereunder, (vii) to the Administrative Agent’s or such Bank’s, as the case may be, legal counsel,
independent auditors and other professional advisors and agents involved in the administration of
the Loans hereunder, or (viii) to any actual or proposed Participant, Purchasing Bank, hedge
counterparty in respect of this Agreement or pledgee (each, a “Transferee”) that has agreed
in writing to be bound by the provisions of this Section 10.16. To the extent permitted by
applicable law, in the event that any Bank or the Administrative Agent is legally requested or
required to disclose any confidential information pursuant to clause (ii), (iii) or (v) of this
Section 10.16, such party shall promptly notify the Borrower of such request or requirement prior
to disclosure so that Borrower may seek an appropriate protective order and/or waive compliance
with the terms of this Agreement. If, however, in the opinion of counsel for such party, such
party is nonetheless, in the absence of such order or waiver, compelled to disclose such
confidential information or otherwise stand liable for contempt or suffer possible censure or other
penalty or liability, then such party may disclose such confidential information without liability
to the Borrower; provided, however, that such party will use its commercially
reasonable efforts to minimize the disclosure of such information. Subject to the exceptions above
to disclosure of information, each of the Banks and the Administrative Agent agrees that it shall
not publish, publicize, or otherwise make public any information regarding this Agreement or the
transactions contemplated hereby without the written consent of the Borrower, in its sole
discretion.

     SECTION 10.17. Officer’s Certificates. It is not intended that any certificate of any officer of the
Borrower delivered to the Administrative Agent or any Bank pursuant to this Agreement shall give

(Title III of Pub. L. 107-56 (signed into law October 26, 2001)) (the “Patriot 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 other information that will allow such Bank or
the Administrative Agent, as applicable, to identify the Borrower in accordance with the Patriot
Act. The Borrower shall, and shall cause each of its Subsidiaries to, provide, to the extent
commercially reasonable, such information and take such actions as are reasonably requested by each
Bank and the Administrative Agent to maintain compliance with the Patriot Act.

     SECTION 10.19. No Advisory or Fiduciary Responsibility. The Borrower acknowledges and agrees, and

between the Borrower or any of its Affiliates, on the one hand, and the Administrative Agent, any
other Agent, any Lead
Arranger, any Global Coordinator, any Issuing Bank, the Swingline Lender or any Bank, on the
other hand, is intended to be or has been created in respect of this Agreement, irrespective of

matters, (b) each of the Administrative Agent, the other Agents, the Lead Arrangers, the Global
Coordinators, the Issuing Banks, the Swingline Lender and the Banks, on the one hand, and the
Borrower and its Affiliates, on the other hand, have an arm’s length business relationship that
does not directly or indirectly give rise to, nor do the Borrower and its Affiliates rely on, any
fiduciary duty to them on the part of the Administrative Agent, any other Agent, any Lead Arranger,
any Global Coordinator, any Issuing Bank, the Swingline Lender or any Bank, (c) the Borrower and
its Affiliates are capable of evaluating and understanding, and each of the Borrower and its
Affiliates understands and accepts, the terms, risks and conditions of the transactions
contemplated by this Agreement and by the other Loan Documents, (d) the Borrower and its Affiliates
have been advised that the Administrative Agent, the other Agents, the Lead Arrangers, the Global
Coordinators, the Issuing Banks, the Swingline Lender and the Banks are engaged in a broad range of
transactions that may involve interests that differ from the interests of the Borrower and its
Affiliates and no such Person has any obligation to disclose such interests and transactions to the
Borrower or any of its Affiliates, (e) the Borrower and its Affiliates have consulted their own
legal, accounting, regulatory and tax advisors to the extent they have deemed appropriate, and (f)
each of the Administrative Agent, the other Agents, the Lead Arrangers, the Global Coordinators,
the Issuing Banks, the Swingline Lender and the Banks has been, is, and will be acting solely as a
principal and, except as otherwise expressly agreed in writing by it and the relevant parties, has
not been, is not, and will not be acting as an advisor, agent or fiduciary for the Borrower or any
of its Affiliates or any other Person or entity in respect of the transactions contemplated by this
Agreement.
