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 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 outstanding, which, when added to such Bank’s Revolving
Percentage of the sum of (i) then outstanding L/C Obligations and (ii) the then outstanding
principal amount of the Swingline Loans, does not exceed at any time such Bank’s Commitment;
provided that no Loan shall be made as a LIBOR Rate Loan with an Interest Period ending
after the Termination Date; and provided, further, that in no event shall the Total
Outstanding Extensions of Credit at any time exceed the Total Commitments at such time.

     (b) Each Borrowing by the Borrower shall be in an aggregate principal amount not less than
$10,000,000 (in the case of LIBOR Rate Loans) or $5,000,000 (in the case of ABR Loans), or an
integral multiple of $1,000,000 in excess thereof and shall consist of Loans of the same Type made
on the same day by the Banks ratably according to their respective Revolving Percentages. Each
Swingline Loan shall be in an amount equal to $500,000 or a whole multiple of $100,000 in excess
thereof. Within the limits of the applicable Commitments, the Borrower may borrow, prepay pursuant
to Section 4.6 and reborrow under this Section 2.1. The principal amount outstanding on the Loans
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
under the Commitments 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 Loans comprising such Borrowing,
(iii) aggregate amount of such Borrowing and (iv) the Interest Period for each such Loan, in the
case of any LIBOR Rate Loan:

     (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 LIBOR Rate Loan;

     (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 an Early Funding ABR Loan; 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 any other ABR Loan.

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 date of such Borrowing, 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 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 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 ABR (in the case of ABR Loans) or (ii) the Federal Funds Effective Rate (in
the case of LIBOR 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

26

 

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. Minimum Tranches. All Borrowings, prepayments, conversions and
continuations of Loans hereunder and all selections of Interest Periods hereunder shall be in such
amounts and be made pursuant to such elections so that, after giving effect thereto, the aggregate
principal amount of the Loans comprising each Tranche of LIBOR Rate Loans shall be equal to
$10,000,000 or an integral multiple of $1,000,000 in excess thereof.

     SECTION 2.4. Swingline Loans. (a) Subject to the terms and conditions set forth herein,
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 $100,000,000 (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. 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 LIBOR 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 first date after such
Swingline Loan is made that is the 15th or last day of a calendar month and is at least two
Business Days after such Swingline Loan is made; provided that on each date that a
Revolving Loan is made, the Borrower shall repay all Swingline Loans.

          (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 telecopy or email), 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. Each Borrowing under the Swingline Commitment shall be in an amount equal to $1,000,000
or a whole multiple in excess 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 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 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 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 Bank. 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 Banks have issued the Existing
Letters of Credit which from and after the Closing Date shall constitute Letters of Credit

Existing Issuing Banks), 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, without limitation, 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 neither JPMorgan Chase Bank, N.A. nor SunTrust Bank shall be required,

28

$100,000,000 at any time outstanding for each such Issuing Bank.

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.

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 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, and such other certificates, documents and other papers and information as such
Issuing Bank may reasonably request. Upon receipt of any Application, the Issuing Bank will
process such Application and the certificates, documents and other papers and information delivered
to it in connection therewith in accordance with its customary procedures and shall promptly issue
the Letter of Credit requested thereby (but in no event shall any Issuing Bank be required to issue
any Letter of Credit earlier than two Business Days after its receipt of the Application therefor
and all such other certificates, documents and other papers and information relating thereto) by
issuing the original of such Letter of Credit 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 to the Borrower promptly following the
issuance thereof and notify the Banks of the amount thereof.

     (c) Fees, Commissions and Other Charges.

     (i) The Borrower shall pay to the Administrative Agent, for the account of the relevant
Issuing Bank and the L/C Participants, a letter of credit commission fee with respect to
each Letter of Credit, computed for the period from the last L/C Fee Payment Date (or, if
later, the date of issuance thereof) to the date upon which such payment is due hereunder at
the rate per annum equal to the Applicable Margin for LIBOR Rate Loans then in effect,
calculated on the basis of a 365- (or 366-, as the case may be) day year, of the aggregate
amount available to be drawn under such Letter of Credit on the date on which such fee is
calculated. 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, computed for
the period from the last L/C Fee Payment Date to the date upon which such payment is due
hereunder at the rate per annum equal to 0.125%, calculated on the basis of a 365- (or 366-,
as the case may be) day year, of the aggregate amount available to be drawn under such
Letter of Credit on the date on which such fee is calculated. Such commissions and fronting
fees shall be payable in arrears on each L/C Fee Payment Date and shall be nonrefundable.

29

 

     (ii) In addition to the foregoing fees and commissions, 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 and commissions
received by the Administrative Agent for their respective accounts pursuant to this Section
2.5(c).

     (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

30

 

at the ABR. 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 on 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 timely notice or 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 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 of such Issuing Bank or violation of the standards of care
specified in the Uniform Commercial Code of the State of New York.

     (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

31

 

Credit may be transferred or
(iii) any claims whatsoever of the Borrower against any beneficiary of such Letter of
Credit
or any such transferee.

     (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 or in violation of the standards of care
specified in the Uniform Commercial Code of the State of New York.

     (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 and in accordance with the standards of
care specified in the Uniform Commercial Code of the State of New York, 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 of the Issuing Bank. Any Issuing Bank may be replaced at any time by
written agreement among the Borrower, the Administrative Agent, the replaced Issuing Bank and the
successor Issuing Bank. The Administrative Agent shall notify the 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, (i) the applicable successor Issuing
Bank shall have all the rights and obligations of such Issuing Bank under this Agreement with
respect to Letters of Credit to be issued thereafter and (ii) references herein to the term
“Issuing Bank” shall be deemed to refer to such successor or to any previous Issuing Bank, or to
such successor and all previous Issuing Banks, as the context shall require. After the replacement
of an Issuing Bank hereunder, the applicable 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.

     SECTION 2.6. Increase in the Aggregate Commitments. (a) The Borrower may,
at any time, whether or not the Commitments have been reduced pursuant to Section 4.5, by notice to

32

 

the Administrative Agent, request that the aggregate amount of the Commitments be increased by an
amount of $10,000,000 or an integral multiple of $5,000,000 in excess thereof (a “Commitment
Increase”) to be effective as of a date that is at least 90 days prior to the scheduled
Termination Date then in effect (the “Increase Date”) as specified in the related notice to
the Administrative Agent; provided, however, that (i) in no event shall the
aggregate amount of the Commitments at any time exceed $1,800,000,000 and (ii) 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 5.2 shall be satisfied.

     (b) The Administrative Agent shall promptly notify the Banks of a request by the Borrower for
a Commitment Increase, which notice shall include (i) the proposed amount of such requested
Commitment Increase, (ii) the proposed Increase Date and (iii) the date by which the Banks wishing
to participate in the Commitment Increase must commit to an increase in the amount of their
respective Commitments (the “Commitment Date”). Each Bank that is willing, in its sole
discretion, to participate in such requested Commitment Increase (each an “Increasing
Bank”) shall give written notice to the Administrative Agent and the Borrower on or prior to
the Commitment Date of the amount by which it is willing to increase its Commitment. If the Banks
notify the Administrative Agent and the Borrower that they are willing to increase the amount of
their respective Commitments by an aggregate amount that exceeds the amount of the requested
Commitment Increase, the requested Commitment Increase shall be allocated among the Banks willing
to participate therein in such amounts as are agreed between the Borrower and the Administrative
Agent.

     (c) Promptly following each Commitment Date, the Administrative Agent shall notify the
Borrower as to the amount, if any, by which the Banks are willing to participate in the requested
Commitment Increase. If the aggregate amount by which the Banks are willing to participate in any
requested Commitment Increase on any such Commitment Date is less than the requested Commitment
Increase, then the Borrower may request Banks to increase their participation and extend offers to
one or more Eligible Assignees to participate in any portion of
the requested Commitment Increase that has not been committed to by the Lenders as of the
applicable Commitment Date; provided, however, that the Revolving Commitment of
each such Eligible Assignee shall be in an amount not less than $10,000,000.

     (d) On each Increase Date, each Eligible Assignee that accepts an offer to participate in a
requested Commitment Increase in accordance with Section 2.6(b) (each such Eligible Assignee, an
“Assuming Bank”) shall become a Bank party to this Agreement as of such Increase Date and
the Commitment of each Increasing Bank for such requested Commitment Increase shall be so increased
by such amount (or by the amount allocated to such Bank pursuant to the last sentence of Section
2.6(b)) as of such Increase Date; provided, however, that the Administrative Agent
shall have received on or before such Increase Date the following, each dated such date:

     (i) (A) certified copies of resolutions of the Board of Directors of the
Borrower or the Executive Committee of such Board approving the Commitment Increase
and the corresponding modifications to this Agreement and (B) opinions of counsel
for the Borrower (which may be in-house counsel), in form and

33

 

substance reasonably
acceptable to the Administrative Agent, covering the matters covered by the opinions
of counsel delivered pursuant to Section 5.1(c);

     (ii) an assumption agreement from each Assuming Bank, if any, substantially in
the form of Exhibit E hereto (each an “Assumption Agreement”), duly
executed by such Eligible Assignee, the Administrative Agent and the Borrower; and

     (iii) confirmation from each Increasing Bank of the increase in the amount of
its Commitment in a writing satisfactory to the Borrower and the Administrative
Agent.

On each Increase Date, upon fulfillment of the conditions set forth in the immediately preceding
sentence of this Section 2.6(d), the Administrative Agent shall notify the Banks (including,
without limitation, each Assuming Bank) and the Borrower, on or before 1:00 P.M. (New York City
time), by telecopier, of the occurrence of the Commitment Increase to be effected on such Increase
Date and shall record in the Register the relevant information with respect to each Increasing Bank
and each Assuming Bank on such date.

     (e) The Administrative Agent shall promptly notify the Borrower and the Banks of any increase
in the amount of the aggregate Commitments pursuant to this Section and of the respective adjusted
Commitment and Revolving Percentage of each Bank after giving effect thereto. The Borrower
acknowledges that, in order to maintain the Revolving Percentage of each Bank, a non-pro-rata
increase in the aggregate Commitments may require prepayment or funding of all or portions of
certain Loans on the date of such increase (and any such prepayment or funding shall be subject to
the other provisions of this Agreement). Effective upon such 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 increase.

     SECTION 2.7. Extension Option. The Borrower may request that the Commitments be
extended for 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 Lender agrees, in its individual and sole discretion, to extend its
Commitment (such Lender, an “Extending Lender”), 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 Lenders’ decisions no later than
25 days after such Notice Date. The Extending Lenders’ Commitments will be extended for an
additional year from the Termination Date (the “Extended Termination Date”) or the Extended
Termination Date (the “Second Extended Termination Date”); provided that (i) more
than 50% of the Commitments is extended or otherwise committed to by Extending Lenders and any new
Lenders and (ii) on the date of any request by the Borrower to extend the Commitments, the
applicable conditions set forth in Section 5.2 shall be satisfied. No Lender shall be required to
consent to any such extension request and any Lender that declines or does not respond to the
Borrower’s request for commitment renewal (a “Declining Lender”) will have its Commitment
terminated on the then existing Termination Date (without regard to any renewals by other

34

 

Lenders).
The Borrower will have the right to accept commitments from Eligible Assignees in an amount equal
to the amount of the Commitments of any Declining Lenders; provided that the Extending
Lenders will have the right to increase their Commitments up to the amount of the Declining
Lenders’ Commitments before the Borrower will be permitted to substitute any Eligible Assignees for
the Declining Lenders. The Borrower may only extend the Termination Date twice during the term of
this Agreement pursuant to this Section 2.7.

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, without limitation, 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.

     SECTION 3.2. Fees. (a) The Borrower agrees to pay to the Administrative Agent for
the account of each Bank the Commitment Fee, from the date hereof until such date that the Loans
and other obligations under this Agreement have been paid in full, payable quarterly in arrears on
the last day of each March, June, September and December until such date that the Loans and other
obligations under this Agreement have been paid in full and on such date of payment in full.

     (b) The Borrower agrees to pay to the Administrative Agent for the account of each Bank the
applicable Utilization Fee on the Outstanding Extensions of Credit of such Bank at any time that
the Total Outstanding Extensions of Credit outstanding shall exceed 50% of the Total Commitments
then in effect, payable quarterly in arrears on the last day of each March, June, September and
December.

35

 

     (c) The fees payable under Sections 3.2(a) and 3.2(b) 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
fee is payable.

     (d) 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 ABR plus the Applicable Margin
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) LIBOR Rate Loans. Each LIBOR Rate Loan shall bear interest at a rate per annum
equal at all times to, in the case of each LIBOR Rate Loan, the lesser of (A) the sum of the LIBOR
Rate for the applicable Interest Period for such Loan plus the Applicable Margin and (B)
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.

     (c) Swingline Loans. Each Swingline Loan shall bear interest at a rate per annum
equal to the lesser of (i)(A) the ABR plus that Applicable Margin 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 ABR 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, Utilization 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 (as well after as before judgment).

36

 

     (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 LIBOR 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 LIBOR 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 LIBOR 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 LIBOR 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 LIBOR Rate Loans made by such Bank outstanding
on such day;

     (ii) the difference between (A) a fraction, the numerator of which is the LIBOR Rate
(expressed as a decimal) applicable to such LIBOR 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 LIBOR 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.

37

 

     (b) If, with respect to any LIBOR Rate Loans, prior to the first day of an Interest Period (i)
the Administrative Agent shall have determined (which determination shall be conclusive and binding
upon the Borrower) that, by reason of circumstances affecting the London interbank market, adequate
and reasonable means do not exist for ascertaining the LIBOR Rate for such Interest Period or (ii)
the Administrative Agent shall have received notice from the Majority Banks that the LIBOR 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 affected LIBOR Rate Loans during such Interest Period, the Administrative Agent
shall give facsimile or telephonic notice thereof (with written notice to follow promptly) to the
Borrower and the Banks as soon as practicable thereafter. If such notice is given, (A) any LIBOR
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
LIBOR Rate Loans shall be continued as ABR Loans and (C) any outstanding LIBOR Rate Loans shall be
converted, on the first day of such Interest Period, to ABR Loans. Until such notice has been
withdrawn by the Administrative Agent, no further LIBOR Rate Loans shall be made or continued as
such, nor shall the Borrower have the right to convert Loans to LIBOR Rate Loans.

     SECTION
3.6. Voluntary Interest Conversion or Continuation of Loans. (a) The Borrower
may on any Business Day, upon the Borrower’s irrevocable oral or written notice of interest
conversion/continuation given by the Borrower to the
Administrative Agent 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 LIBOR Rate
Loan, (i) convert Loans of one Type into Loans of another Type; (ii) convert LIBOR Rate Loans for a
specified Interest Period into LIBOR Rate Loans for a different Interest Period; or (iii) continue
LIBOR Rate Loans for a specified Interest Period as LIBOR Rate Loans for the same Interest Period;
provided, however, that (A) any conversion of any LIBOR Rate Loans into LIBOR Rate
Loans for a different Interest Period, or into ABR Loans, or any continuation of LIBOR Rate Loans
for the same Interest Period shall be made on, and only on, the last day of an Interest Period for
such LIBOR Rate Loans; (B) no Loan may be converted into or continued as a LIBOR Rate Loan by the
Borrower so long as an Event of Default has occurred and is continuing, and (C) no Loan may be
converted into or continued as a LIBOR Rate Loan if after giving effect thereto, Section 2.3 would
be contravened. With respect to any oral notice of interest conversion/continuation given by the
Borrower under this Section 3.6(a), the Borrower shall promptly thereafter confirm such notice in
writing. 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 the requested (x) date of such interest conversion or
continuation; (y) the Loans to be converted or continued; and (z) if such interest conversion or
continuation is into LIBOR Rate Loans, the duration of the Interest Period for each such LIBOR Rate
Loan. 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. This Section shall not apply to Swingline Borrowings,
which may not be converted or continued.

38

 

     (b) If the Borrower shall fail to deliver to the Administrative Agent a Notice of Interest
Conversion/Continuation in accordance with Section 3.6(a) hereof, or to select the duration of any
Interest Period for the principal amount outstanding under any LIBOR Rate Loan by 11:00 A.M. (New
York City time) on the third Business Day prior to the last day of the Interest Period applicable
to such Loan in accordance with Section 3.6(a), 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 such Loans will automatically, on the last day of the then
existing Interest Period therefor, convert into LIBOR Rate Loans with a one month Interest Period.

     SECTION 3.7. Funding Losses Relating to LIBOR 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 LIBOR
Rate Loan, (ii) default by the Borrower in making a borrowing of, conversion into or continuation
of any LIBOR 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 after the
Borrower has given a notice thereof in accordance with the provisions of this Agreement or (iv) the
making of a prepayment of LIBOR Rate Loans or the conversion of LIBOR Rate Loans into ABR Loans,
on a day that is not the last day of an Interest Period with respect thereto (excluding any
prepayment made pursuant to Section 3.8) on a day that is not the scheduled maturity date with
respect thereto, including, without limitation, in each case, any such loss or expense arising from
the reemployment of funds obtained by it 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 LIBOR Rate Loan exceed the amounts that would have been payable
assuming such Bank had actually funded its relevant LIBOR Rate Loan through the purchase of a
deposit bearing interest at the LIBOR Rate in an amount equal to the amount of such LIBOR Rate Loan
and having a maturity comparable to, with respect to any LIBOR Rate Loan, the relevant Interest
Period, provided, that each Bank may fund each of its LIBOR 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 LIBOR Rate Loans or to fund or maintain LIBOR

39

 

Rate Loans hereunder,
(i) the obligation of such Bank to make, or to convert Loans into, or to continue LIBOR Rate Loans
as, LIBOR 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 LIBOR Rate Loans of such Bank then outstanding, or convert all
such Loans to ABR Loans, on the respective last days of the then current Interest Periods with
respect to such 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
LIBOR Rate Loans due to it 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 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 of this Agreement:

     (i) 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 LIBOR Rate hereunder (except for amounts covered by Section 3.4 or any other Section
hereof); or

     (ii) 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 LIBOR
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

40

 

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.

     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.

41

 

     (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 LIBOR 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.

     SECTION 4.3. Taxes. (a) Any and all payments by the Borrower hereunder or under the
Loan Documents 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, deductions, charges or
withholdings, and all liabilities with respect thereto, excluding, in the case of each Bank and the
Administrative Agent, net income taxes, branch profits taxes and franchise taxes imposed on it as a
result of a present or former connection between the jurisdiction (or political subdivision
thereof) of the government or taxing authority imposing such tax and the Administrative Agent or
such Bank other than a connection arising solely from the Administrative Agent or such Bank having
executed, delivered or performed its obligations or received a payment under, or enforced, this
Agreement or any Note (all such non-excluded taxes, levies, imposts, deductions, charges,
withholdings and liabilities being hereinafter referred to as “Taxes”). If the Borrower
shall be required by law to deduct any Taxes from or in respect of any sum payable hereunder or
under any Note to any Bank or the Administrative Agent, (i) the sum payable shall be increased as
may be necessary so that after making all required deductions (including deductions applicable to
additional sums payable under this Section 4.3) such 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 been
made; (ii) the Borrower shall make such deductions and (iii) the Borrower shall pay the full amount
deducted to the relevant taxation authority or other authority in accordance with applicable law;
provided, however, that the Borrower shall not be required to increase any such
sums payable to any Bank with respect to any Taxes (i) that are attributable to such Bank’s failure
to comply with the requirements of Section 4.3(d) or (ii) that are United States withholding taxes
imposed on sums payable to such Bank at the time such Bank becomes a party to this Agreement (or
maintains a lending office), except to the extent that any such Bank’s assignor (if any) was
entitled, at the time of assignment, to receive additional amounts from the Borrower with respect
to such Taxes pursuant to this Section 4.3. Whenever any Taxes or Other Taxes (as defined in
Section 4.3(b)) are payable by the Borrower, as promptly as

42

 

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) official tax receipts or notarized copies of such receipts to such Bank
within thirty (30) days after payment of any applicable tax 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 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 or registration 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
Taxes or Other Taxes (including, without limitation, any 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 liability (including penalties, interest and expenses) arising
therefrom or with respect thereto, including, without limitation or duplication, any incremental
taxes, interest or penalties that may become payable by the Administrative Agent or any Bank as a
result of any failure by the Borrower to pay any Taxes or Other Taxes when due to the appropriate
taxing authority or to remit to any Bank the receipts or other evidence of payment of Taxes or
Other Taxes.

     (d) Each Bank registered in the Register that is not a U.S. Person as defined in Section
7701(a)(30) of the Code agrees that it will deliver to the Borrower and the Administrative Agent on
the date hereof, or on the date which it becomes a party to this Agreement, two duly completed
copies of United States Internal Revenue Service Form W-8BEN, W-8ECI W-8EXP or W-8IMY (or other
appropriate corresponding form) or any successor applicable form, as the case may be. Each such
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 or successor applicable forms or other manner of
certification, 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, and such extensions or renewals thereof
as may reasonably be requested by the Borrower or the Administrative Agent, unless in any such case
an event (including, without limitation, any change in treaty, law or regulation) has occurred
prior to the date on which any such delivery would otherwise be required that renders all such
forms inapplicable or that would prevent such Bank from duly completing and delivering any such
form with respect to it and such Bank so advises the Borrower and the Administrative Agent. Each
such Bank shall certify in the case of a Form W-8BEN, W-8ECI, W-8EXP, or W-8IMY that it is entitled
to receive payments under this Agreement without deduction or withholding of any United States
federal income taxes, subject to notification to the Borrower otherwise pursuant to this Section
4.3(d). In the event that any such Bank fails to deliver any forms required under this Section
4.3(d), the Borrower’s obligation to pay additional amounts shall be reduced to the amount that it
would have been obligated to pay had such forms been provided.

43

 

     (e) If any Taxes or Other Taxes are not correctly or legally asserted and the Administrative
Agent or any Bank determines, in its reasonable discretion, that it has received a refund of those
Taxes or Other Taxes as to which it has been indemnified by the Borrower, 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 (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.

     (f) 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 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.

44

 

     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 and (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.

          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) not later than 11:00 A.M. (New York City time) on the same Business Day (or in the case of
LIBOR Rate Loans, two (2) Business Days (or such shorter or no notice as may be satisfactory to the
Administrative Agent), and in the case of prepayment of a Swingline Loan, not later than 12:00
noon, New York City time, on the date of prepayment) before the date of prepayment 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;
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, and the payment amount specified
in such notice shall be due and payable on the prepayment date described in such notice, together
with accrued and unpaid interest on the amount prepaid. Partial prepayments pursuant to this
Section 4.6 with respect to any Tranche of LIBOR 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 LIBOR Rate Loans then
outstanding, as the case may be; provided that no partial prepayment of any Tranche of
LIBOR Rate Loans may be made if, after giving effect thereto, Section 2.3 would be contravened.
Partial prepayments with respect to the ABR Loans shall be made in an aggregate principal amount
equal to the lesser of (i) $5,000,000 or an integral multiple of $1,000,000 in excess thereof or
(ii) the aggregate principal amount of ABR Loans then outstanding, as the case may be.

45

 

     SECTION 4.7. Mitigation of Losses and Costs. 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, without limitation, 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.

     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.

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 those that have been obtained.

     (f) Obligations Binding. This Agreement and the other Loan Documents to which the
Borrower is a party are 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 by any 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 support commercial paper issued by the Borrower, and (ii) 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 the Properties reflected in the
financial statements referred to in Section 6.1(m) and in any financial statements delivered
pursuant to Section 7.1(a), except for such Properties that have been disposed of subsequent to the
dates of the balance sheets included in such financial statements and that are no longer used or
useful in the conduct of the business of the Borrower or any Significant Subsidiary or that have
been disposed of pursuant to Section 7.2(c) or (e) or that have been disposed of in the ordinary
course of their respective business, 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, 2006, there has been no event,
development or circumstance that, as of the Closing Date, has or would reasonably be expected to
have a Material Adverse Effect.

50

 

     (k) Litigation. As of the Closing Date, there is no litigation, action, suit,
investigation or other legal or governmental proceeding pending or, to the best knowledge of the
Borrower, threatened, at law or in equity, or before or by any arbitrator or Governmental Authority
(i) relating to the transactions under this Agreement or under any other Loan Document or (ii) in
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 twelve months ended December 31, 2006 filed with the SEC with the Borrower’s 10-K 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, 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) provided by the Borrower to the Banks in connection
with or pursuant to this Agreement or the other Loan Documents contains as of the date thereof or
will contain as of the date thereof any untrue statement of a material fact or omits or will omit
to state as of the date thereof a 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 of such information; 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.

51

 

     (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 obligations under this Agreement and the other Loan
Documents constitute “Senior Debt” of the Borrower under and as defined in the ZENS Indenture and
under any indenture governing any Junior Subordinated Debt.

     (r) Taxes. The Borrower and each of its Subsidiaries has filed or caused to be filed
all Federal, state and other material tax returns that are required to be filed and has 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 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).

through the Administrative Agent) may reasonably request.

Information required to be delivered pursuant to the foregoing Sections 7.1(a)(i), (ii), and
(iv)(A) 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

Subsidiary to, preserve and maintain all of its Property that is material to the conduct of its
business, provided, however, that nothing in this Section 7.1(d) shall prevent (a)
the Borrower or any of its Significant Subsidiaries from selling, abandoning or otherwise disposing
of any Properties (including the Capital Stock of any Subsidiary of the Borrower that is not a
Significant Subsidiary), the retention of which 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 the failure to maintain would not reasonably be expected to have
a Material Adverse Effect or (b) any other transaction that is expressly permitted by the terms of
any other provision of this Agreement.

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; 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 of its Significant Subsidiaries
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.

to the Borrower, then automatically:

     (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 and, while such Event of
Default is continuing, the Administrative Agent, having been so instructed by the Majority Banks,
by notice to the Borrower shall so 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

     With respect to all Letters of Credit with respect to which presentment for honor shall not

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 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 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

62

 

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 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 Provisions. Neither any Agent nor any of their respective
officers, directors, employees, agents, 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 for 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

63

 

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 note, writing, resolution,
notice, consent, certificate, affidavit, letter, facsimile, telex or teletype message, 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, without limitation, 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.

     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; 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 and Other Banks. Each Bank
expressly acknowledges that neither the Agents nor any of their respective officers, directors,
employees, agents, attorneys-in-fact or Affiliates have made any representations or warranties to
it and that no act by any Agent hereinafter taken, including any review of the affairs of the
Borrower, shall be deemed to constitute any representation or warranty by any Agent to any Bank.
Each Bank represents to the Agents that it has, independently and without reliance upon

64

 

any Agent
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 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,
attorneys-in-fact or Affiliates.

     SECTION 9.7. Indemnification. The Banks agree to indemnify the Agents and the Lead
Arrangers in their respective capacities as such (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, 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, without limitation, at any time following the payment of all amounts
owing hereunder and the termination of the Commitments) be imposed on, incurred by or asserted
against the Agents or the Lead Arrangers, as the case may be, in any way relating to or arising
out of 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 the Agents or the Lead Arrangers, as the case may be, 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 resulting from the Agents’ or the Lead Arrangers’, as the case may
be, gross negligence or willful misconduct. The agreements in this Section 9.7 shall survive the
payment of all 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 30 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

65

 

agent for the Banks, which
successor agent shall be approved by the Borrower, 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 Agent or any of the parties to
this Agreement or any holders of any amounts payable hereunder; provided that if an Event
of Default has occurred and is continuing, no consent of the Borrower shall be required. If a
successor Administrative Agent shall not have been so appointed within said 30-day period, the
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 New York City 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 as provided above. After any retiring Administrative Agent’s resignation or removal as
Administrative Agent, the provisions of this Article X shall 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.

     Notwithstanding anything to the contrary contained herein, no Bank identified as an “Agent”,
“Arranger” or “Global Coordinator” other than the Administrative Agent, shall have the right,
power, obligation, liability, responsibility or duty under this Agreement or any 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

Loan Document, nor any terms hereof or thereof may be amended, supplemented or modified except

of the Banks and shall be binding upon the Borrower, the Banks, the Issuing Bank or Issuing Banks,
the Administrative Agent and all future holders of the amounts payable hereunder. In the case of

Banks, and the Administrative Agent shall be restored to their former position and rights hereunder
and under any outstanding Notes and any other Loan Documents, and any Default or Event of Default

subsequent or other Default or Event of Default, or impair any right consequent thereon.

provided that any notice, request or demand to or upon the Administrative Agent or the
Banks shall not be effective until received.

     (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

68

 

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.”

     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 and Taxes; Indemnity. The Borrower agrees (a) to
pay all reasonable out-of-pocket expenses of the Global Coordinators associated with the
syndication of the Facility, (b) to pay or reimburse the Administrative Agent and its Affiliates
for all its reasonable out-of-pocket costs and expenses incurred in connection with the
development, preparation, negotiation and execution and delivery of, and any amendment, supplement
or modification to, this Agreement and any Notes 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, without limitation, the reasonable
fees and disbursements of Simpson Thacher & Bartlett LLP, special counsel to the Administrative
Agent (but excluding the fees or expenses of any other counsel), (c) to pay or reimburse the
Administrative Agent for all its costs and expenses incurred in connection with the enforcement or
preservation of any rights under this Agreement, any Notes, the other Loan Documents and any such
other documents, including, without limitation, the reasonable fees and disbursements of the
special counsel to the Administrative Agent, (d) 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 any rights under
this Agreement, any Notes, the other Loan Documents and any such other documents, including,
without limitation, the reasonable fees and disbursements of counsel to such Bank, (e) 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,
if any, and any and all liabilities (for which each Bank has not been otherwise reimbursed under
this Agreement) with respect to, or resulting from any delay in paying, stamp, excise and other
taxes, if any, that may be payable or determined to be payable in connection with the execution and
delivery of, or consummation or

69

 

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, any Notes, the other Loan Documents and any such other documents, and (f) without
duplication of any other provision contained in this Agreement or any Notes, to pay, indemnify, and
hold each Global Coordinator, each Lead Arranger, each Bank, each Swingline Lender and each Agent
together with their respective directors, officers, employees, agents, trustees, advisors and
affiliates (collectively, “Indemnified Persons”) harmless from and against, any and all
other liabilities, obligations, losses, damages, penalties, actions, judgments, suits, costs,
expenses or disbursements of any kind or nature whatsoever (including without limitation, all fees
and expenses of counsel to any indemnified person) with respect to the execution, delivery,
enforcement, performance and administration of this
Agreement, any Notes or the other Loan Documents, the transactions contemplated by this
Agreement, any Notes or the other Loan Documents, or the use, or proposed use, of proceeds of the
Loans (all the foregoing in this clause (f), collectively, the “Indemnified Liabilities”);
provided that the Borrower shall have no obligation hereunder to an Indemnified Person with
respect to Indemnified Liabilities arising from the gross negligence or willful misconduct of such
Indemnified Person, AND PROVIDED FURTHER THAT IT IS THE INTENTION OF THE BORROWER TO INDEMNIFY THE
INDEMNIFIED PERSONS AGAINST THE CONSEQUENCES OF THEIR OWN NEGLIGENCE. The agreements in this
Section 10.5 shall survive repayment of the Loans and all other amounts payable hereunder.

     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, 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, to the extent provided
in its participation, shall be entitled to the benefits of Sections 3.4, 3.7, 4.1 and 4.3 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

70

 

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. 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.

     (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, 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, (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

71

 

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 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 not evidenced by a Note 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) Each of the Banks and the Administrative Agent agrees to exercise its best efforts to
keep, and to cause any third party recipient of the information described in this Section 10.6(f)
to keep, 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, (iii) upon the request or demand of any Governmental Authority having
jurisdiction over such Bank, (iv) if such information has been publicly disclosed, (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, (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, or (viii) to any actual or proposed Participant, Purchasing Bank or
pledgee (each, a “Transferee”) that has agreed in writing to be bound by the provisions of
this Section 10.6(f). 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 10.6(f), 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 best efforts to minimize the disclosure of such information. Subject to
the exceptions above to disclosure of information, each of the Banks and

72

 

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.

     (g) If, pursuant to this Section 10.6, any interest in this Agreement or any Loan or L/C
Obligation is transferred to any Transferee that is organized under the laws of any jurisdiction
other than the United States or any state thereof, the transferor Bank shall cause such Transferee,
concurrently with the effectiveness of such transfer, (i) to deliver to the transferor Bank (and,
in the case of any Purchasing Bank registered in the Register, the Administrative Agent and the
Borrower) either U.S. Internal Revenue Service Form W-8BEN or U.S. Internal Revenue Service
Form W-8ECI, or successor applicable forms (wherein such Transferee claims entitlement to complete
exemption from U.S. federal withholding tax on all interest payments hereunder) and (ii) to agree
(for the benefit of the transferor Bank, the Administrative Agent and the Borrower) to deliver to
the transferor Bank (and, in the case of any Purchasing Bank registered in the Register, the
Administrative Agent and Borrower) a new Form duly executed and completed W-8BEN or W-8ECI, or
successor applicable forms or other manner of certification, as the case may be, upon the
expiration or obsolescence of any previously delivered form in accordance with applicable U.S. laws
and regulations and amendments, unless in any such case any change in treaty, law or regulation has
occurred prior to the date on which any such delivery would otherwise be required that renders all
such forms inapplicable or that would prevent such Transferee from duly completing and delivering
any such form with respect to it and such Transferee so advises the transferor Bank (and, in the
case of any Purchasing Bank registered in the Register, the Administrative Agent and the Borrower).

     (h) 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, 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, each Bank shall have the right, without prior notice to the Borrower, any such notice being
expressly waived by the Borrower to the extent permitted by applicable law, upon any amount
becoming due and payable by the Borrower hereunder or under the Loans to which it is a party
(whether at the stated maturity, by acceleration or otherwise) to setoff and appropriate and apply
against such amount 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. 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.

73

 

     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 ANY NOTES OR OTHER LOAN
DOCUMENTS AND THE RIGHTS AND OBLIGATIONS OF THE PARTIES UNDER THIS AGREEMENT AND ANY NOTES AND ANY
OTHER LOAN DOCUMENTS SHALL BE GOVERNED BY, AND CONSTRUED AND INTERPRETED IN ACCORDANCE WITH, THE
LAW 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 (formerly known as the
indicated (weekly) rate ceiling in Article 1.04, Subtitle 1, Title 79, of the Revised Civil
Statutes of Texas, as amended) 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 (formerly found in Chapter 15 of Subtitle 3, Title 79, of the Revised
Civil Statutes of Texas, 1925, 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

74

 

Courts of the State of New York, 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;

     (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; and

     (e) waives, to the maximum extent permitted by applicable law, any right it may have to claim
or recover in any legal action or proceeding any special, exemplary, punitive or consequential
damages.

     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, any Notes 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

75

 

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 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
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 Commitments 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 Bank hereunder.

76

 

     SECTION 10.16. 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 10.17. USA Patriot Act. Each Bank and the Administrative Agent (for itself
and not on behalf of any Lender) hereby notifies the Borrower that pursuant to the requirements of
the USA Patriot Act (Title III of Pub. L. 107-56 (signed into law October 26, 2001)) (the
“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.

77

 

          IN WITNESS WHEREOF, the parties hereto have caused this Agreement to be executed by their
respective officers thereunto duly authorized, as of the date first above written.

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 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 outstanding, which, when added to such Bank’s Revolving Percentage of
the sum of (i) then outstanding L/C Obligations and (ii) the then outstanding principal amount of
the Swingline
Loans, does not exceed at any time such Bank’s

22

 

Commitment; provided that no Loan shall
be made as a LIBOR Rate Loan with an Interest Period ending after the Termination Date; and
provided, further, that in no event shall the Total Outstanding Extensions of
Credit at any time exceed the Total Commitments at such time.

     (b) Each Borrowing by the Borrower shall be in an aggregate principal amount not less than
$10,000,000 (in the case of LIBOR Rate Loans) or $5,000,000 (in the case of ABR Loans), or an
integral multiple of $1,000,000 in excess thereof and shall consist of Loans of the same Type made
on the same day by the Banks ratably according to their respective Revolving Percentages. Each
Swingline Loan shall be in an amount that is equal to $500,000 or a whole multiple of $100,000 in
excess thereof. Within the limits of the applicable Commitments, the Borrower may borrow, prepay
pursuant to Section 4.6 and reborrow under this Section 2.1. The principal amount outstanding on
the Loans 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 under the
Commitments 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 Loans
comprising such Borrowing, (iii) aggregate amount of such Borrowing and (iv) the Interest Period
for each such Loan, in the case of any LIBOR Rate Loan:

     (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 LIBOR Rate Loan;

     (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 an Early Funding ABR Loan; 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 any other ABR Loan.

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 date of such Borrowing, 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 Loans received by the Administrative Agent hereunder
by crediting such account of the Borrower which the Administrative Agent and the

23

 

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 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 ABR (in the case of ABR Loans) or (ii) the Federal Funds Effective Rate (in
the case of LIBOR 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. Minimum Tranches. All Borrowings, prepayments, conversions and continuations of Loans
hereunder and all selections of Interest Periods hereunder shall be in such amounts and be made
pursuant to such elections so that, after giving effect thereto, the aggregate principal amount of
the Loans comprising each Tranche of LIBOR Rate Loans shall be equal to $10,000,000 or an integral
multiple of $1,000,000 in excess thereof.

     SECTION
2.4. Swingline Loans. (a) Subject to the terms and conditions set forth herein, 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. The Swingline Loans may from time to
time be (i) ABR Loans, (ii) Money

24

 

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 LIBOR 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 first date after such Swingline Loan is made that is the 15th or last day of a calendar
month and is at least two Business Days after such Swingline Loan is made; provided that on
each date that a Revolving Loan is made, the Borrower shall repay all Swingline Loans.

          (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
telecopy or email), 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.
Each Borrowing under the Swingline Commitment shall be in an amount equal to $1,000,000 or a whole
multiple in excess 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 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 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 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 Bank. 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

25

 

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 Banks have 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, each Issuing Bank (other than the
Existing Issuing Banks), 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, without limitation, 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 neither JPMorgan Chase Bank, N.A. nor Wachovia Bank, National
Association shall be required, without the consent of such Issuing Bank, to issue Letters of
Credit in excess of $37,500,000 at any time outstanding for each such Issuing Bank.

     (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) Each Letter of Credit shall be subject to the Uniform Customs and, to the extent
not inconsistent therewith, the laws of the State of New York.

     (v) 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 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

26

 

Issuing
Bank, and such other certificates, documents and other papers and information as such Issuing Bank may reasonably request. Upon receipt of any Application, the Issuing Bank will
process such Application and the certificates, documents and other papers and information delivered
to it in connection therewith in accordance with its customary procedures and shall promptly issue
the Letter of Credit requested thereby (but in no event shall any Issuing Bank be required to issue
any Letter of Credit earlier than two Business Days after its receipt of the Application therefor
and all such other certificates, documents and other papers and information relating thereto) by
issuing the original of such Letter of Credit 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 to the Borrower promptly following the
issuance thereof and notify the Banks of the amount thereof.

     (c) Fees, Commissions and Other Charges.

     (i) The Borrower shall pay to the Administrative Agent, for the account of the relevant
Issuing Bank and the L/C Participants, a letter of credit commission fee with respect to
each Letter of Credit, computed for the period from the last L/C Fee Payment Date (or, if
later, the date of issuance thereof) to the date upon which such payment is due hereunder at
the rate per annum equal to the Applicable Margin for LIBOR Rate Loans then in effect,
calculated on the basis of a 365- (or 366-, as the case may be) day year, of the aggregate
amount available to be drawn under such Letter of Credit on the date on which such fee is
calculated. 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, computed for
the period from the last L/C Fee Payment Date to the date upon which such payment is due
hereunder at the rate per annum equal to 0.125%, calculated on the basis of a 365- (or 366-,
as the case may be) day year, of the aggregate amount available to be drawn under such
Letter of Credit on the date on which such fee is calculated. Such commissions 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 and commissions, 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 and commissions
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

27

 

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 ABR. 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

28

 

before the
date of such payment if the Borrower receives notice of such payment on 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 timely notice or 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 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 of such Issuing Bank or violation of the standards of care
specified in the Uniform Commercial Code of the State of New York.

     (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 or
(iii) any claims whatsoever of the Borrower against any beneficiary of such Letter of Credit
or any such transferee.

     (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 or in violation of the standards of care
specified in the Uniform Commercial Code of the State of New York.

     (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 and in accordance with the standards of
care specified in the Uniform Commercial Code of the State of New York, shall be binding on
the Borrower and shall not result in any liability of such Issuing Bank to the Borrower.

29

 

     (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 of the Issuing Bank. Any Issuing Bank may be replaced at any time by
written agreement among the Borrower, the Administrative Agent, the replaced Issuing Bank and the
successor Issuing Bank. The Administrative Agent shall notify the 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, (i) the applicable successor Issuing
Bank shall have all the rights and obligations of such Issuing Bank under this Agreement with
respect to Letters of Credit to be issued thereafter and (ii) references herein to the term
“Issuing Bank” shall be deemed to refer to such successor or to any previous Issuing Bank, or to
such successor and all previous Issuing Banks, as the context shall require. After the replacement
of an Issuing Bank hereunder, the applicable 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.

     SECTION
2.6. Increase in the Aggregate Commitments. (a) The Borrower may, at any time, whether or not
the Commitments have been reduced pursuant to Section 4.5, by notice to the Administrative Agent,
request that the aggregate amount of the Commitments be increased by an amount of $10,000,000 or an
integral multiple of $5,000,000 in excess thereof (a “Commitment Increase”) to be effective
as of a date that is at least 90 days prior to the scheduled Termination Date then in effect (the
“Increase Date”) as specified in the related notice to the Administrative Agent; provided,
however, that (i) in no event shall the aggregate amount of the Commitments at any time exceed
$450,000,000 and (ii) 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 5.2 shall be satisfied.

     (b) The Administrative Agent shall promptly notify the Banks of a request by the Borrower for
a Commitment Increase, which notice shall include (i) the proposed amount of such requested
Commitment Increase, (ii) the proposed Increase Date and (iii) the date by which the Banks wishing
to participate in the Commitment Increase must commit to an increase in the amount of their
respective Commitments (the “Commitment Date”). Each Bank that is willing, in its sole
discretion, to participate in such requested Commitment Increase (each an “Increasing
Bank”) shall give written notice to the Administrative Agent and the Borrower on or prior to
the Commitment Date of the amount by which it is willing to increase its Commitment. If the Banks

30

 

notify the Administrative Agent and the Borrower that they are willing to increase the amount of
their respective Commitments by an aggregate amount that exceeds the amount of the requested
Commitment Increase, the requested Commitment Increase shall be allocated among the Banks willing
to participate therein in such amounts as are agreed between the Borrower and the Administrative
Agent.

     (c) Promptly following each Commitment Date, the Administrative Agent shall notify the
Borrower as to the amount, if any, by which the Banks are willing to participate in the requested
Commitment Increase. If the aggregate amount by which the Banks are willing to participate in any
requested Commitment Increase on any such Commitment Date is less than the requested Commitment
Increase, then the Borrower may request Banks to increase their participation and extend offers to
one or more Eligible Assignees to participate in any portion of the requested Commitment Increase
that has not been committed to by the Lenders as of the applicable Commitment Date;
provided, however, that the Revolving Commitment of each such Eligible Assignee
shall be in an amount not less than $10,000,000.

     (d) On each Increase Date, each Eligible Assignee that accepts an offer to participate in a
requested Commitment Increase in accordance with Section 2.6(b) (each such Eligible Assignee, an
“Assuming Bank”) shall become a Bank party to this Agreement as of such Increase Date and
the Commitment of each Increasing Bank for such requested Commitment Increase shall be so increased
by such amount (or by the amount allocated to such Bank pursuant to the last sentence of Section
2.6(b)) as of such Increase Date; provided, however, that the Administrative Agent
shall have received on or before such Increase Date the following, each dated such date:

     (i) (A) certified copies of resolutions of the Board of Directors (or other
governing body) of the Borrower or the Executive Committee of such Board (or other
governing body) approving the Commitment Increase and the corresponding
modifications to this Agreement 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 the matters covered by the opinions of counsel
delivered pursuant to Section 5.1(c);

     (ii) an assumption agreement from each Assuming Bank, if any, substantially in
the form of Exhibit E hereto (each an “Assumption Agreement”), duly
executed by such Eligible Assignee, the Administrative Agent and the Borrower; and

     (iii) confirmation from each Increasing Bank of the increase in the amount of
its Commitment in a writing satisfactory to the Borrower and the Administrative
Agent.

On each Increase Date, upon fulfillment of the conditions set forth in the immediately preceding
sentence of this Section 2.6(d), the Administrative Agent shall notify the Banks (including,
without limitation, each Assuming Bank) and the Borrower, on or before 1:00 P.M. (New York City
time), by telecopier, of the occurrence of the Commitment Increase to be effected on such Increase
Date and shall record in the Register the relevant information with respect to each Increasing Bank
and each Assuming Bank on such date.

31

 

     (e) The Administrative Agent shall promptly notify the Borrower and the Banks of any increase
in the amount of the aggregate Commitments pursuant to this Section and of the respective adjusted
Commitment and Revolving Percentage of each Bank after giving effect thereto. The Borrower
acknowledges that, in order to maintain the Revolving Percentage of each Bank, a non-pro-rata
increase in the aggregate Commitments may require prepayment or funding of all or portions of
certain Loans on the date of such increase (and any such prepayment or funding shall be subject to
the other provisions of this Agreement). Effective upon such 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 increase.

     SECTION
2.7. Extension Option. The Borrower may request that the Commitments be extended for 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 Lender agrees, in its individual and sole discretion, to extend its Commitment (such Lender,
an “Extending Lender”), 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 Lenders’ decisions no later than 25 days after such
Notice Date. The Extending Lenders’ Commitments will be extended for an additional year from the
Termination Date (the “Extended Termination Date”) or the Extended Termination Date (the
“Second Extended Termination Date”); provided that (i) more than 50% of the Commitments is
extended or otherwise committed to by Extending Lenders and any new Lenders and (ii) on the date of
any request by the Borrower to extend the Commitments, the applicable conditions set forth in
Section 5.2 shall be satisfied. No Lender shall be required to consent to any such extension
request and any Lender that declines or does not respond to the Borrower’s request for commitment
renewal (a “Declining Lender”) will have its Commitment terminated on the then existing
Termination Date (without regard to any renewals by other Lenders). The Borrower will have the
right to accept commitments from Eligible Assignees in an amount equal to the amount of the
Commitments of any Declining Lenders; provided that the Extending Lenders will have the right to
increase their Commitments up to the amount of the Declining Lenders’ Commitments before the
Borrower will be permitted to substitute any Eligible Assignees for the Declining Lenders. The
Borrower may only extend the Termination Date twice during the term of this Agreement pursuant to
this Section 2.7.

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, without limitation, 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

32

 

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.

     SECTION
3.2. Fees. (a) The Borrower agrees to pay to the Administrative Agent for the account of
each Bank the Commitment Fee, from the date hereof until such date that the Loans and other
obligations under this Agreement have been paid in full, payable quarterly in arrears on the last
day of each March, June, September and December until such date that the Loans and other
obligations under this Agreement have been paid in full and on such date of payment in full.

     (b) The Borrower agrees to pay to the Administrative Agent for the account of each Bank the
applicable Utilization Fee on the Outstanding Extensions of Credit of such Bank at any time that
the Total Outstanding Extensions of Credit outstanding shall exceed 50% of the Total Commitments
then in effect, payable quarterly in arrears on the last day of each March, June, September and
December.

     (c) The fees payable under Sections 3.2(a) and 3.2(b) 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
fee is payable.

     (d) 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 ABR plus the Applicable Margin
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) LIBOR Rate Loans. Each LIBOR Rate Loan shall bear interest at a rate per annum
equal at all times to, in the case of each LIBOR Rate Loan, the lesser of (A) the sum of the LIBOR
Rate for the applicable Interest Period for such Loan plus the Applicable Margin and

33

 

(B) 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.

     (c) Swingline Loans. Each Swingline Loan shall bear interest at a rate per annum
equal to the lesser of (i)(A) the ABR plus the Applicable Margin 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 ABR 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, Utilization 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 (as well after 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 LIBOR
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 LIBOR 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 LIBOR 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

34

 

applicability of the foregoing reserves to such LIBOR 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 LIBOR Rate Loans made by such Bank outstanding
on such day;

     (ii) the difference between (A) a fraction, the numerator of which is the LIBOR Rate
(expressed as a decimal) applicable to such LIBOR 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 LIBOR
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, with respect to any LIBOR Rate Loans, prior to the first day of an Interest Period (i)
the Administrative Agent shall have determined (which determination shall be conclusive and binding
upon the Borrower) that, by reason of circumstances affecting the London interbank market, adequate
and reasonable means do not exist for ascertaining the LIBOR Rate for such Interest Period or (ii)
the Administrative Agent shall have received notice from the Majority Banks that the LIBOR 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 affected LIBOR Rate Loans during such Interest Period, the Administrative Agent
shall give facsimile or telephonic notice thereof (with written notice to follow promptly) to the
Borrower and the Banks as soon as practicable thereafter. If such notice is given, (A) any LIBOR
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
LIBOR Rate Loans shall be continued as ABR Loans and (C) any outstanding LIBOR Rate Loans shall be
converted, on the first day of such Interest Period, to ABR Loans. Until such notice has been
withdrawn by the Administrative Agent, no further LIBOR Rate Loans shall be made or continued as
such, nor shall the Borrower have the right to convert Loans to LIBOR Rate Loans.

     SECTION
3.6. Voluntary Interest Conversion or Continuation of Loans. (a) The Borrower may on any
Business Day, upon the Borrower’s irrevocable oral or written notice

35

 

of interest
conversion/continuation given by the Borrower to the Administrative Agent 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 LIBOR Rate Loan, (i) convert Loans of one Type into
Loans of another Type; (ii) convert LIBOR Rate Loans for a specified Interest Period into LIBOR
Rate Loans for a different Interest Period; or (iii) continue LIBOR Rate Loans for a specified
Interest Period as LIBOR Rate Loans for the same Interest Period; provided,
however, that (A) any conversion of any LIBOR Rate Loans into LIBOR Rate Loans for a
different Interest Period, or into ABR Loans, or any continuation of LIBOR Rate Loans for the same
Interest Period shall be made on, and only on, the last day of an Interest Period for such LIBOR
Rate Loans; (B) no Loan may be converted into or continued as a LIBOR Rate Loan by the Borrower so
long as an Event of Default has occurred and is continuing, and (C) no Loan may be converted into
or continued as a LIBOR Rate Loan if after giving effect thereto, Section 2.3 would be contravened.
With respect to any oral notice of interest conversion/continuation given by the Borrower under
this Section 3.6(a), the Borrower shall promptly thereafter confirm such notice in writing. 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 the requested (x) date of such interest conversion or
continuation; (y) the Loans to be converted or continued; and (z) if such interest conversion or
continuation is into LIBOR Rate Loans, the duration of the Interest Period for each such LIBOR Rate
Loan. 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. This Section shall not apply to Swingline Borrowings,
which may not be converted or continued.

     (b) If the Borrower shall fail to deliver to the Administrative Agent a Notice of Interest
Conversion/Continuation in accordance with Section 3.6(a) hereof, or to select the duration of any
Interest Period for the principal amount outstanding under any LIBOR Rate Loan by 11:00 A.M. (New
York City time) on the third Business Day prior to the last day of the Interest Period applicable
to such Loan in accordance with Section 3.6(a), 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 such Loans will automatically, on the last day of the then
existing Interest Period therefor, convert into LIBOR Rate Loans with a one month Interest Period.

     SECTION
3.7. Funding Losses Relating to LIBOR 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 LIBOR
Rate Loan, (ii) default by the Borrower in making a borrowing of, conversion into or continuation
of any LIBOR 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 after the
Borrower has given a notice thereof in accordance with the provisions of this Agreement or (iv) the
making of a prepayment of LIBOR Rate Loans or the conversion of LIBOR Rate Loans into ABR Loans, on
a day that is not the last day of an Interest Period with respect thereto (excluding any prepayment
made pursuant to Section 3.8) on

36

 

a day that is not the scheduled maturity date with respect
thereto, including, without limitation, in each case, any such loss or expense arising from the
reemployment of funds obtained by it 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 LIBOR Rate Loan exceed the amounts that would have been payable
assuming such Bank had actually funded its relevant LIBOR Rate Loan through the purchase of a
deposit bearing interest at the LIBOR Rate in an amount equal to the amount of such LIBOR Rate Loan
and having a maturity comparable to, with respect to any LIBOR Rate Loan, the relevant Interest
Period, provided, that each Bank may fund each of its LIBOR 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 LIBOR Rate Loans or to fund or maintain LIBOR Rate Loans hereunder,
(i) the obligation of such Bank to make, or to convert Loans into, or to continue LIBOR Rate Loans
as, LIBOR 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 LIBOR Rate Loans of such Bank then outstanding, or convert all
such Loans to ABR Loans, on the respective last days of the then current Interest Periods with
respect to such 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
LIBOR Rate Loans due to it 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 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 of this Agreement:

     (i) 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 LIBOR Rate hereunder (except for amounts covered by Section 3.4 or any other Section
hereof); or

     (ii) 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 LIBOR
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
Section 4.8(b), additional amounts, computed by such Bank in accordance with Section 4.8(a),

38

 

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.

     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 LIBOR 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

39

 

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.

     SECTION
4.3. Taxes. (a) Any and all payments by the Borrower hereunder or under the Loan
Documents 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, deductions, charges or withholdings, and all
liabilities with respect thereto, excluding, in the case of each Bank and the Administrative Agent,
net income taxes, branch profits taxes and franchise taxes imposed on it as a result of a present
or former connection between the jurisdiction (or political subdivision thereof) of the government
or taxing authority imposing such tax and the Administrative Agent or such Bank other than a
connection arising solely from the Administrative Agent or such Bank having executed, delivered or
performed its obligations or received a payment under, or enforced, this Agreement or any Note (all
such non-excluded taxes, levies, imposts, deductions, charges, withholdings and liabilities being
hereinafter referred to as “Taxes”). If the Borrower shall be required by law to deduct
any Taxes from or in respect of any sum payable hereunder or under any Note to any Bank or the
Administrative Agent, (i) the sum payable shall be increased as may be necessary so that after
making all required deductions (including deductions applicable to additional sums payable under
this Section 4.3) such 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 been made; (ii) the Borrower shall
make such deductions and (iii) the Borrower shall pay the full amount deducted to the relevant
taxation authority or other authority in accordance with applicable law; provided,
however, that the Borrower shall not be required to increase any such sums payable to any
Bank with respect to any Taxes (i) that are attributable to such Bank’s failure to comply with the
requirements of Section 4.3(d) or (ii) that are United States withholding taxes imposed on sums
payable to such Bank at the time such Bank becomes a party to this Agreement (or maintains a
lending office), except to the extent that any such Bank’s assignor (if any) was entitled, at the
time of assignment, to receive additional amounts from the Borrower with respect to such Taxes
pursuant to this Section 4.3. Whenever any Taxes or Other Taxes (as defined in Section 4.3(b)) are
payable by the Borrower, 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) official tax receipts or notarized copies of such receipts to such Bank within
thirty (30) days after payment of any applicable tax 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 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 or registration 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
Taxes or Other Taxes (including, without limitation, any 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 liability (including penalties, interest and

40

 

expenses) arising
therefrom or with respect thereto, including, without limitation or duplication, any incremental
taxes, interest or penalties that may become payable by the Administrative Agent or any Bank as a
result of any failure by the Borrower to pay any Taxes or Other Taxes when due to the appropriate
taxing authority or to remit to any Bank the receipts or other evidence of payment of Taxes or
Other Taxes.

     (d) Each Bank registered in the Register that is not a U.S. Person as defined in Section
7701(a)(30) of the Code agrees that it will deliver to the Borrower and the Administrative Agent on
the date hereof, or on the date which it becomes a party to this Agreement, two duly completed
copies of United States Internal Revenue Service Form W-8BEN, W-8ECI W-8EXP or W-8IMY (or other
appropriate corresponding form) or any successor applicable form, as the case may be. Each such
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 or successor applicable forms or other manner of
certification, 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, and such extensions or renewals thereof
as may reasonably be requested by the Borrower or the Administrative Agent, unless in any such case
an event (including, without limitation, any change in treaty, law or regulation) has occurred
prior to the date on which any such delivery would otherwise be required that renders all such
forms inapplicable or that would prevent such Bank from duly completing and delivering any such
form with respect to it and such Bank so advises the Borrower and the Administrative Agent. Each
such Bank shall certify in the case of a Form W-8BEN, W-8ECI, W-8EXP, or W-8IMY that it is entitled
to receive payments under this Agreement without deduction or withholding of any United States
federal income taxes, subject to notification to the Borrower otherwise pursuant to this Section
4.3(d). In the event that any such Bank fails to deliver any forms required under this Section
4.3(d), the Borrower’s obligation to pay additional amounts shall be reduced to the amount that it
would have been obligated to pay had such forms been provided.

     (e) If any Taxes or Other Taxes are not correctly or legally asserted and the Administrative
Agent or any Bank determines, in its reasonable discretion, that it has received a refund of those
Taxes or Other Taxes as to which it has been indemnified by the Borrower, 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 (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.

     (f) 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

41

 

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 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 and (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.

          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

42

 

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) not
later than 11:00 A.M. (New York City time) on the same Business Day (or in the case of LIBOR Rate
Loans, two (2) Business Days (or such shorter or no notice as may be satisfactory to the
Administrative Agent), and in the case of prepayment of a Swingline Loan, not later than 12:00
noon, New York City time, on the date of prepayment) before the date of prepayment 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;
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, and the payment amount specified
in such notice shall be due and payable on the prepayment date described in such notice, together
with accrued and unpaid interest on the amount prepaid. Partial prepayments pursuant to this
Section 4.6 with respect to any Tranche of LIBOR 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 LIBOR Rate Loans then
outstanding, as the case may be; provided that no partial prepayment of any Tranche of
LIBOR Rate Loans may be made if, after giving effect thereto, Section 2.3 would be contravened.
Partial prepayments with respect to the ABR Loans shall be made in an aggregate principal amount
equal to the lesser of (i) $5,000,000 or an integral multiple of $1,000,000 in excess thereof or
(ii) the aggregate principal amount of ABR Loans then outstanding, as the case may be.

     SECTION
4.7. Mitigation of Losses and Costs. 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, without
limitation, 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.

     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

43

 

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.

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

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 have a Material Adverse Effect.

46

 

     (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 has been, and each other Loan

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, any order to which the

Borrower; (ii) violate, conflict with, result in a breach of or constitute (with due notice or
lapse of time or both, or any other condition) 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, conflicts, breaches or defaults that, individually
or in the aggregate, do not have or would not have a Material Adverse Effect); or (iii) 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,

other Loan Documents to which it is a party, except those that have been obtained.

     (f) Obligations Binding. This Agreement and the other Loan Documents to which the
Borrower is a party are the legal, valid and binding obligations of the Borrower enforceable

authorization, execution and delivery of this Agreement by any 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).

Borrower (i) to support commercial paper issued by the Borrower and (ii) 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

made to the Borrower will be used for any purpose that would violate the provisions of the margin
regulations of the Board.

47

 

     (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 the Properties reflected in the
financial statements referred to in Section 6.1(m) and in any financial statements delivered
pursuant to Section 7.1(a), except for such Properties that have been disposed of subsequent to the
dates of the balance sheets included in such financial statements and that are no longer used or
useful in the conduct of the business of the Borrower or any Significant Subsidiary or that have
been disposed of pursuant to Section 7.2(c) or (d) or that have been disposed of in the ordinary
course of their respective business, 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, 2006, there has been no event,
development or circumstance that, as of the Closing Date, has 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 pending or, to the best knowledge of the
Borrower, threatened, at law or in equity, or before or by any arbitrator or Governmental Authority
(i) relating to the transactions under this Agreement or under any other Loan Document or (ii) in
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 twelve months ended December 31, 2006 filed with the SEC with the Borrower’s 10-K 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, 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).

48

 

     (n) Accuracy of Information. None of the documents or written information (excluding
estimates, financial projections and forecasts) provided by the Borrower to the Banks in connection
with or pursuant to this Agreement or the other Loan Documents contains as of the date thereof or
will contain as of the date thereof any untrue statement of a material fact or omits or will omit
to state as of the date thereof a 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 of such information; 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) Taxes. The Borrower and each of its Subsidiaries has filed or caused to be filed
all Federal, state and other material tax returns that are required to be filed and has 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 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).

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)(A) 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 (i) such notice may be included in a

Credit made or issued by the Banks or any Issuing Bank to it for the purposes set forth in Section
6.1(g), and it will not use the proceeds of any Loan or Letter of Credit made or issued by the

Subsidiary to, preserve and maintain all of its Property that is material to the conduct of its
business, provided, however, that nothing in this Section 7.1(d) shall prevent (a)
the Borrower or any of its Significant Subsidiaries from selling, abandoning or otherwise disposing
of any Properties (including the Capital Stock of any Subsidiary of the Borrower that is not a
Significant Subsidiary), the retention of which 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 the failure to maintain would not reasonably be expected to have
a Material Adverse Effect or (b) any other transaction that is expressly permitted by the terms of
any other provision of this Agreement.

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; 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 of its Significant Subsidiaries
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.

52

such time to Consolidated Capitalization for the most recently ended fiscal quarter to exceed 65%.

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 Restricted Subsidiary of the Borrower now or
hereafter owned directly or indirectly by the Borrower; provided, however, that
this restriction shall neither apply to nor prevent the creation or existence of:

     (i) Permitted Liens;

     (ii) (A) any Lien in existence on the date hereof; provided that no such Lien
described in this clause (ii) encumbers any additional Property after the date hereof and

Mortgage (to the extent the proceeds thereof are used to replace, refund or refinance first

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 Restricted 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

of the Borrower and not created in contemplation of such Person becoming a Restricted
Subsidiary of the Borrower (or on repairs, renewals, replacements, additions, accessions and

unless such Indebtedness is permitted under Section 7.2(a);

     (xii) Liens on cash collateral to secure obligations of the Borrower and its Restricted
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 of
the Borrower and its Restricted Subsidiaries so long as the aggregate outstanding principal
amount of the obligations secured thereby does not at any time exceed at the time of
incurrence of such obligations (including any such incurrence resulting from any extension,
renewal or refunding of such obligations), as to the Borrower and all of its Restricted
Subsidiaries, 10% of Net Tangible Assets.

     (c) Consolidation, Merger or Disposal of Assets. And will not permit any Significant
Subsidiary to, (i) consolidate with, or merge into or amalgamate with or into, any other Person;

prior to such time in accordance with the other provisions of this Agreement and was not agreed to
or incurred in contemplation of such change of status, (iv) any 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,

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

58

 

     (b) any other Event of Default specified in Section 8.1 occurs and, while such Event of
Default is continuing, the Administrative Agent, having been so instructed by the Majority Banks,
by notice to the Borrower shall so 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

     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 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 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 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 Provisions. Neither any Agent nor any of their respective
officers, directors, employees, agents, 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 for 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 note, writing, resolution,
notice, consent, certificate, affidavit, letter, facsimile, telex or teletype message, statement,
order or other document or conversation believed by it to be genuine and correct and to have been
signed,

60

 

sent or made by the proper Person or Persons and upon advice and statements of legal counsel
(including, without limitation, 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.

     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;
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 and Other Banks. Each Bank
expressly acknowledges that neither the Agents nor any of their respective officers, directors,
employees, agents, attorneys-in-fact or Affiliates have made any representations or warranties to
it and that no act by any Agent hereinafter taken, including any review of the affairs of the
Borrower, shall be deemed to constitute any representation or warranty by any Agent to any Bank.
Each Bank represents to the Agents that it has, independently and without reliance upon any Agent
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 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

61

 

of the Borrower that may come into the possession of the Administrative Agent or any of its
officers, directors, employees, attorneys-in-fact or Affiliates.

     SECTION 9.7. Indemnification. The Banks agree to indemnify the Agents and the Lead
Arrangers in their respective capacities as such (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, 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, without limitation, at any time following the payment of all amounts
owing hereunder and the termination of the Commitments) be imposed on, incurred by or asserted
against the Agents or the Lead Arrangers, as the case may be, in any way relating to or arising out
of 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 the Agents or the Lead Arrangers, as the case may be, 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 resulting from the Agents’ or the Lead Arrangers’, as the case may be, gross
negligence or willful misconduct. The agreements in this Section 9.7 shall survive the payment of
all 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 30 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 be approved by the Borrower, 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 Agent or any of the parties to
this Agreement or any holders of any amounts payable hereunder; provided that if an Event
of Default has occurred and is continuing, no consent of the Borrower shall be required. If a
successor Administrative Agent shall not have been so appointed within said 30-day period, the
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 New York City 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 as provided above. After any retiring

62

 

Administrative Agent’s resignation or removal as Administrative Agent, the provisions of this
Article X shall 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.

     Notwithstanding anything to the contrary contained herein, no Bank identified as an “Agent”,
“Arranger” or “Global Coordinator” other than the Administrative Agent, shall have the right,
power, obligation, liability, responsibility or duty under this Agreement or any 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

Loan Document, nor any terms hereof or thereof may be amended, supplemented or modified except
pursuant to an instrument or instruments in writing executed in accordance with the provisions of
this Section 10.1. The Majority Banks may, or, with the written consent of the Majority Banks, the
Administrative Agent may, from time to time, (a) enter into with the Borrower written amendments,

any manner the rights of the Banks or of the Borrower hereunder or thereunder or (b) waive, on such
terms and conditions as the Majority Banks or the Administrative Agent, as the case may be, may

affects any Swingline Lender without the written consent of the then Swingline Lender or
Swingline Lenders.

of the Banks and shall be binding upon the Borrower, the Banks, the Issuing Bank or Issuing Banks,
the Administrative Agent and all future holders of the amounts payable hereunder. In the case of
any waiver (to the extent specified therein), the Borrower, the Banks, the Issuing Bank or Issuing
Banks, and the Administrative Agent shall be restored to their former position and rights hereunder
and under any outstanding Notes and any other Loan Documents, and any Default or Event of Default
waived shall be deemed to be cured and not continuing, but no such waiver shall extend to any
subsequent or other Default or Event of Default, or impair any right consequent thereon.

     (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.”

     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 and Taxes; Indemnity. The Borrower agrees (a) to
pay all reasonable out-of-pocket expenses of the Global Coordinators associated with the
syndication of the Facility, (b) to pay or reimburse the Administrative Agent and its Affiliates
for all its reasonable out-of-pocket costs and expenses incurred in connection with the
development, preparation, negotiation and execution and delivery of, and any amendment, supplement
or modification to, this Agreement and any Notes 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, without limitation, the reasonable
fees and disbursements of Simpson Thacher & Bartlett LLP, special counsel to the Administrative
Agent (but excluding the fees or expenses of any other counsel), (c) to pay or reimburse the
Administrative Agent for all its costs and expenses incurred in connection with the enforcement or
preservation of any rights under this Agreement, any Notes, the other Loan Documents and any such
other documents, including, without limitation, the reasonable fees and disbursements of the
special counsel to the Administrative Agent, (d) 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 any rights under
this Agreement, any Notes, the other Loan Documents and any such other documents, including,
without limitation, the reasonable fees and disbursements of counsel to such Bank, (e) 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,
if any, and any and all liabilities (for which each Bank has not been otherwise reimbursed under
this Agreement) with respect to, or resulting from any delay in paying, stamp, excise and other
taxes, 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, any Notes, the other Loan Documents and any such other documents, and (f) without
duplication of any other provision contained in this Agreement or any Notes, to pay, indemnify, and
hold each Global Coordinator, each Lead Arranger, each Bank, each Swingline Lender and each Agent
together with their respective directors, officers, employees, agents, trustees, advisors and
affiliates (collectively, “Indemnified Persons”) harmless from and against, any and all
other liabilities, obligations, losses, damages, penalties, actions, judgments, suits, costs,
expenses or disbursements of any kind or nature whatsoever (including without limitation, all fees
and expenses of counsel to any indemnified person) with respect to the execution, delivery,
enforcement, performance and administration of this Agreement, any Notes or the other Loan

66

 

Documents, the transactions contemplated by this Agreement, any Notes or the other Loan
Documents, or the use, or proposed use, of proceeds of the Loans (all the foregoing in this clause
(f), collectively, the “Indemnified Liabilities”); provided that the Borrower shall
have no obligation hereunder to an Indemnified Person with respect to Indemnified Liabilities
arising from the gross negligence or willful misconduct of such
Indemnified Person, AND PROVIDED
FURTHER THAT IT IS THE INTENTION OF THE BORROWER TO INDEMNIFY THE INDEMNIFIED PERSONS AGAINST THE
CONSEQUENCES OF THEIR OWN NEGLIGENCE. The agreements in this Section 10.5 shall survive repayment
of the Loans and all other amounts payable hereunder.

     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, 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, to the extent provided
in its participation, shall be entitled to the benefits of Sections 3.4, 3.7, 4.1 and 4.3 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. 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.

     (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, 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

67

 

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, (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 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 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 not evidenced by a Note 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.

68

 

     (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) Each of the Banks and the Administrative Agent agrees to exercise its best efforts to
keep, and to cause any third party recipient of the information described in this Section 10.6(f)
to keep, 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, (iii) upon the request or demand of any Governmental Authority having
jurisdiction over such Bank, (iv) if such information has been publicly disclosed, (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, (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, or (viii) to any actual or proposed Participant, Purchasing Bank or
pledgee (each, a “Transferee”) that has agreed in writing to be bound by the provisions of
this Section 10.6(f). 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 10.6(f), 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 best 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.

     (g) If, pursuant to this Section 10.6, any interest in this Agreement or any Loan or L/C
Obligation is transferred to any Transferee that is organized under the laws of any jurisdiction
other than the United States or any state thereof, the transferor Bank shall cause such Transferee,
concurrently with the effectiveness of such transfer, (i) to deliver to the transferor Bank (and,
in the case of any Purchasing Bank registered in the Register, the Administrative Agent and the
Borrower) either U.S. Internal Revenue Service Form W-8BEN or U.S. Internal Revenue Service Form
W-8ECI, or successor applicable forms (wherein such Transferee claims entitlement to complete
exemption from U.S. federal withholding tax on all interest payments hereunder) and

69

 

(ii) to agree (for the benefit of the transferor Bank, the Administrative Agent and the
Borrower) to deliver to the transferor Bank (and, in the case of any Purchasing Bank registered in
the Register, the Administrative Agent and Borrower) a new Form duly executed and completed W-8BEN
or W-8ECI, or successor applicable forms or other manner of certification, as the case may be, upon
the expiration or obsolescence of any previously delivered form in accordance with applicable U.S.
laws and regulations and amendments, unless in any such case any change in treaty, law or
regulation has occurred prior to the date on which any such delivery would otherwise be required
that renders all such forms inapplicable or that would prevent such Transferee from duly completing
and delivering any such form with respect to it and such Transferee so advises the transferor Bank
(and, in the case of any Purchasing Bank registered in the Register, the Administrative Agent and
the Borrower).

     (h) 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, 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 Exhibit 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, each Bank shall have the right, without prior notice to the Borrower, any such notice being
expressly waived by the Borrower to the extent permitted by applicable law, upon any amount
becoming due and payable by the Borrower hereunder or under the Loans to which it is a party
(whether at the stated maturity, by acceleration or otherwise) to setoff and appropriate and apply
against such amount 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. 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.

70

 

     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 ANY NOTES OR OTHER LOAN
DOCUMENTS AND THE RIGHTS AND OBLIGATIONS OF THE PARTIES UNDER THIS AGREEMENT AND ANY NOTES AND ANY
OTHER LOAN DOCUMENTS SHALL BE GOVERNED BY, AND CONSTRUED AND INTERPRETED IN ACCORDANCE WITH, THE
LAW 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 (formerly known as the
indicated (weekly) rate ceiling in Article 1.04, Subtitle 1, Title 79, of the Revised Civil
Statutes of Texas, as amended) 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 (formerly found in Chapter 15 of Subtitle 3, Title 79, of the Revised
Civil Statutes of Texas, 1925, 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, 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;

71

 

     (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; and

     (e) waives, to the maximum extent permitted by applicable law, any right it may have to claim
or recover in any legal action or proceeding any special, exemplary, punitive or consequential
damages.

     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, any Notes 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 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

72

 

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 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
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 Commitments 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 Bank hereunder.

     SECTION 10.16. 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 10.17. USA Patriot Act. Each Bank and the Administrative Agent (for itself
and not on behalf of any Lender) hereby notifies the Borrower that pursuant to the requirements of
the USA Patriot Act (Title III of Pub. L. 107-56 (signed into law October 26, 2001)) (the
“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

73

 

reasonably requested by each Bank and the Administrative Agent to maintain compliance with the
Patriot Act.

74

 

          IN WITNESS WHEREOF, the parties hereto have caused this Agreement to be executed by their
respective officers thereunto duly authorized, as of the date first above written.
