ARTICLE II

THE ADVANCES

2.1 Commitment. From and including the Initial Borrowing Date and prior to the
Termination Date, each Bank severally agrees, on the terms and conditions set forth in this
Agreement, (a) to make loans to the Company from time to time (the “Loans”), and (b) to
participate in Facility LCs issued upon the request of the Company from time to time;
provided that, after giving effect to the making of each such Loan and the issuance of each
such Facility LC, such Bank’s Outstanding Credit Exposure shall not exceed its Commitment. In no
event may the Aggregate Outstanding Credit Exposure exceed the Available Commitment. Subject to
the terms and conditions of this Agreement, the Company may borrow, repay and reborrow at any time
prior to the Termination Date. The Commitments shall expire on the Termination Date.

2.2 Repayment. The Aggregate Outstanding Credit Exposure and all other unpaid
obligations of the Company hereunder shall be paid in full on the Termination Date.

2.3 Ratable Loans. Each Advance shall consist of Loans made by the several Banks
ratably according to their Pro Rata Shares.

2.4 Types of Advances. The Advances may be Floating Rate Advances or Eurodollar
Advances (each a “Type” of Advance), or a combination thereof, as selected by the Company
in accordance with Sections 2.8 and 2.9.

2.5 Fees and Changes in Commitments.

(a) The Company agrees to pay to the Agent for the account of each Bank according to its Pro
Rata Share (i) a commitment fee (the “Commitment Fee”) at the Commitment Fee Rate on the
daily Unused Commitment from the Initial Borrowing Date to but not including the date on which this
Agreement is terminated in full and all of the Obligations hereunder have been paid in full and
(ii) a utilization fee at the Utilization Fee Rate on such Bank’s Outstanding Credit Exposure for
any date on which the Aggregate Outstanding Credit Exposure exceeds 50% of the Aggregate
Commitment. The fees payable pursuant to this clause (a) shall be payable quarterly in
arrears on each Payment Date (for the quarter then most recently ended) and on the Termination Date
(for the period then ended for which such fee has not previously been paid) and shall be calculated
for actual days elapsed on the basis of a 360 day year.

(b) The Company may permanently reduce the Aggregate Commitment in whole, or in part ratably
among the Banks in the minimum amount of $10,000,000 (and in multiples of $1,000,000 if in excess
thereof), upon at least five Business Days’ written notice to the Agent, which notice shall specify
the amount of any such reduction; provided that the Aggregate Commitment may not be reduced
below the Aggregate Outstanding Credit Exposure. All accrued Commitment Fees shall be payable on
the effective date of any termination of the obligation of the Banks to make Credit Extensions
hereunder. Upon any permanent reduction in the Aggregate Commitment pursuant to the terms of this
Section 2.5(b), the Agent shall, upon request of the Company, promptly surrender to or upon
the order of the Company one or more Bonds specified by the Company; provided that the
Company remains in compliance with Section 6.10.

(c) The Company may, from time to time, by means of a letter delivered to the Agent
substantially in the form of Exhibit H, request that the Aggregate Commitment be increased
by up to $250,000,000 (in the aggregate during the term of this Agreement) by (i) increasing the
Commitment of one or more Banks which have agreed to such increase in writing pursuant to the
procedures described below (it being understood that no Bank has any obligation to agree to such
increase) and/or (ii) adding one or more commercial banks or other Persons as a party hereto (each
an “Additional Bank”) with a Commitment in an amount agreed to by any such Additional Bank;
provided that no Additional Bank shall be added as a party hereto without the written
consent of the Agent and each LC Issuer (which consents shall not be unreasonably withheld) or if a
Default or an Event of Default exists. Any increase in the Aggregate Commitment pursuant to this
clause (c) shall be effective three Business Days (or such other reasonable period of time
as may be specified by the Agent) after the date on which the Agent has received (A) the applicable
increase letter in the form of Annex 1 to Exhibit H (in the case of an increase in
the Commitment of an existing Bank) or assumption letter in the form of Annex 2 to
Exhibit H (in the case of the addition of a commercial bank or other Person as a new Bank),
in each case signed by all applicable parties; and (b) if the requested increase is to occur before
the FMB Release Date and, after giving effect to such increase, the Aggregate Commitment would
exceed the face amount of all Bonds, additional Bonds in an amount not less than such excess
together with such certificates, opinions of counsel and other documents as the Agent may
reasonably request in connection with the issuance and delivery of such Bonds.. The Agent shall
promptly notify the Company and the Banks of any increase in the amount of the Aggregate Commitment
pursuant to this clause (c) and of the Pro Rata Share of each Bank after giving effect
thereto. The parties hereto agree that, notwithstanding any other provision of this Agreement, the
Agent, the Company, each Additional Bank and each increasing Bank, as applicable, may make
arrangements satisfactory to such parties to cause an Additional Bank or an increasing Bank to
temporarily hold risk participations in the outstanding Loans of the other Banks (rather than fund
its Percentage of all outstanding Loans concurrently with the applicable increase) with a view
toward minimizing breakage costs and transfers of funds in connection with any increase in the
Aggregate Commitment. The Company acknowledges that if, as a result of an increase in the
Aggregate Commitment that is not pro rata among the existing Banks, any Eurodollar Rate Loan is
prepaid or converted (in whole or in part) on a day other than the last day of an Interest Period
therefor, then such prepayment or conversion shall be subject to the provisions of Section
4.4.

2.6 Minimum Amount of Advances. Each Advance shall be in the minimum amount of
$10,000,000 (and in integral multiples of $1,000,000 if in excess thereof); provided that
any Floating Rate Advance may be in the amount of the Available Aggregate Commitment (rounded down,
if necessary, to an integral multiple of $1,000,000).

2.7 Optional Principal Payments. The Company may from time to time prepay, without
penalty or premium, all outstanding Floating Rate Advances or, in a minimum aggregate amount of
$10,000,000 or a higher integral multiple of $1,000,000, any portion of the outstanding Floating
Rate Advances upon one Business Day’s prior notice to the Agent. The Company may from time to time
pay, subject to the payment of any funding indemnification amounts required by Section 4.4
but without penalty or premium, all outstanding Eurodollar Advances or, in a minimum aggregate
amount of $10,000,000 or a higher integral multiple of $1,000,000, any portion of any outstanding
Eurodollar Advance upon three Business Days’ prior notice to the Agent; provided that if
after giving effect to any such prepayment the principal amount of any Eurodollar Advance is less
than $10,000,000, such Eurodollar Advance shall automatically convert into a Floating Rate Advance.

2.8 Method of Selecting Types and Interest Periods for New Advances. The Company
shall select the Type of Advance and, in the case of each Eurodollar Advance, the Interest Period
applicable thereto from time to time. The Company shall give the Agent irrevocable notice (a
“Borrowing Notice”) not later than 12:00 noon (New York time) on the Borrowing Date of each
Floating Rate Advance and not later than 12:00 noon (New York time) three Business Days before the
Borrowing Date for each Eurodollar Advance, specifying:

(i) the Borrowing Date, which shall be a Business Day;

(ii) the aggregate amount of such Advance;

(iii) the Type of Advance selected; and

(iv) in the case of each Eurodollar Advance, the initial Interest Period applicable
thereto.

Promptly after receipt thereof, the Agent will notify each Bank of the contents of each Borrowing
Notice. Not later than 2:00 p.m. (New York time) on each Borrowing Date, each Bank shall make
available its Loan in funds immediately available in New York to the Agent at its address specified
pursuant to Section 14. To the extent funds are received from the Banks, the Agent will
make such funds available to the Company at the Agent’s aforesaid address. No Bank’s obligation to
make any Loan shall be affected by any other Bank’s failure to make any Loan.

2.9 Conversion and Continuation of Outstanding Advances. Floating Rate Advances shall
continue as Floating Rate Advances unless and until such Floating Rate Advances are converted into
Eurodollar Advances pursuant to this Section 2.9 or are repaid in accordance with
Section 2.2 or 2.7. Each Eurodollar Advance shall continue as a Eurodollar Advance
until the end of the then applicable Interest Period therefor, at which time such Eurodollar
Advance shall be automatically converted into a Floating Rate Advance unless (x) such Eurodollar
Advance is or was repaid in accordance with Section 2.2 or 2.7 or (y) the Company
shall have given the Agent a Conversion/Continuation Notice (as defined below) requesting that, at
the end of such Interest Period, such Eurodollar Advance continue as a Eurodollar Advance for the
same or another Interest Period. Subject to the terms of Section 2.6, the Company may
elect from time to time to convert all or any part of a Floating Rate Advance into a Eurodollar
Advance. The Company shall give the Agent irrevocable notice (a “Conversion/Continuation
Notice”) of each conversion of a Floating Rate Advance into a Eurodollar Advance or
continuation of a Eurodollar Advance not later than 12:00 noon (New York time) at least three
Business Days prior to the date of the requested conversion or continuation, specifying:

(i) the requested date, which shall be a Business Day, of such conversion or
continuation;

(ii) the aggregate amount and Type of the Advance which is to be converted or
continued; and

(iii) the amount of the Advance which is to be converted into or continued as a
Eurodollar Advance and the duration of the Interest Period applicable thereto;

provided that no Advance may be continued as, or converted into, a Eurodollar Advance if
(x) such continuation or conversion would violate any provision of this Agreement or (y) a Default
or Event of Default exists.

2.10 Interest Rates, Interest Payment Dates. (a) Subject to Section 2.11,
each Advance shall bear interest as follows:

(i) at any time such Advance is a Floating Rate Advance, at a rate per annum equal to
the Floating Rate from time to time in effect; and

(ii) at any time such Advance is a Eurodollar Advance, at a rate per annum equal to the
Eurodollar Rate for each applicable Interest Period.

Changes in the rate of interest on that portion or any Advance maintained as a Floating Rate
Advance will take effect simultaneously with each change in the Floating Rate.

(b) Interest accrued on each Floating Rate Advance shall be payable on each Payment Date and
on the Termination Date. Interest accrued on each Eurodollar Advance shall be payable on the last
day of its applicable Interest Period, on any date on which such Eurodollar Advance is prepaid and
on the Termination Date. Interest accrued on each Eurodollar Advance having an Interest Period
longer than three months shall also be payable on the last day of each three-month interval during
such Interest Period. Interest on Eurodollar Advances, interest on Floating Rate Advances based on
the Federal Funds Effective Rate and the LC Fee shall be calculated for actual days elapsed on the
basis of a 360-day year. Interest on Floating Rate Advances based on the Prime Rate shall be
calculated for actual days elapsed on the basis of a 365- or 366-day year, as appropriate.
Interest on each Advance shall accrue from and including the date such Advance is made to but
excluding the date payment thereof is received in accordance with Section 2.12. If any
payment of principal of or interest on an Advance shall become due on a day which is not a Business
Day, such payment shall be made on the next succeeding Business Day (unless, in the case of a
Eurodollar Advance, such next succeeding Business Day falls in a new calendar month, in which case
such payment shall be due on the immediately preceding Business Day) and, in the case of a
principal payment, such extension of time shall be included in computing interest in connection
with such payment.

2.11 Rate after Maturity. Any Advance not paid by the Company at maturity, whether by
acceleration or otherwise, shall bear interest until paid in full at a rate per annum equal to the
higher of (i) the rate otherwise applicable thereto plus 1% or (ii) the Floating Rate plus 1%.

2.12 Method of Payment. All payments of principal, interest and fees hereunder shall
be made in immediately available funds to the Agent at its address specified on its signature page
to this Agreement (or at any other Lending Installation of the Agent specified in writing by the
Agent to the Company) not later than 1:00 p.m. (New York time) on the date when due and shall
(except in the case of Reimbursement Obligations for which the applicable LC Issuer has not been
fully indemnified by the Banks, or as otherwise specifically required hereunder) be applied ratably
by the Agent among the Banks. Funds received after such time shall be deemed received on the
following Business Day unless the Agent shall have received from, or on behalf of, the Company a
Federal Reserve reference number with respect to such payment before 4:00 p.m. (New York time) on
the date of such payment. Each payment delivered to the Agent for the account of any Bank shall be
delivered promptly by the Agent in the same type of funds received by the Agent to such Bank at the
address specified for such Bank in its Administrative Questionnaire or at any Lending Installation
specified in a notice received by the Agent from such Bank. The Agent is hereby authorized to
charge the account of the Company maintained with JPMorgan, if any, for each payment of principal,
interest, Reimbursement Obligations and fees as such payment becomes due hereunder. Each reference
to the Agent in this Section 2.12 shall also be deemed to refer, and shall apply equally,
to each LC Issuer, in the case of payments required to be made by the Company to such LC Issuer
pursuant to Section 3.6.

2.13 Bonds; Record-keeping; Telephonic Notices.

(a) The obligation of the Company to repay the Obligations shall be evidenced by one or more
Bonds or, at the request of any Bank following the FMB Release Date, a promissory note in form and

hereunder from the Company and each Bank’s share thereof.

(c) above shall be prima facie evidence of the existence and amounts of the Obligations
therein recorded; provided that the failure of the Agent or any Bank to maintain such
accounts or any error therein shall not in any manner affect the obligation of the Company to repay
the Obligations in accordance with their terms.

(e) The Company hereby authorizes the Banks and the Agent to make Advances based on telephonic
notices made by any person or persons the Agent or any Bank in good faith believes to be acting on
behalf of the Company. The Company agrees to deliver promptly to the Agent a written confirmation
of each telephonic notice signed by a Designated Officer. If the written confirmation differs in
any material respect from the action taken by the Agent and the Banks, the records of the Agent and
the Banks shall govern absent manifest error.

2.14 Lending Installations. Subject to the provisions of Section 4.6, each
Bank may book its Loans and its participation in any LC Obligations and each LC Issuer may book the
Facility LCs issued by it at any Lending Installation selected by such Bank or such LC Issuer, as

by it or Facility LCs will be issued by it and for whose account payments on the Loans or payments
with respect to Facility LCs are to be made.

2.15 Non-Receipt of Funds by the Agent. Unless a Bank or the Company, as the case may
be, notifies the Agent prior to the date on which it is scheduled to make payment to the Agent of
(i) in the case of a Bank, the proceeds of a Loan or (ii) in the case of the Company, a payment of
principal, interest or fees to the Agent for the account of the Banks, that it does not intend to
make such payment, the Agent may assume that such payment has been made. The Agent may, but shall
not be obligated to, make the amount of such payment available to the intended recipient in
reliance upon such assumption. If such Bank or the Company, as the case may be, has not in fact
made such payment to the Agent, the recipient of such payment shall, on demand by the Agent, repay
to the Agent the amount so made available together with interest thereon in respect of each day
during the period commencing on the date such amount was so made available by the Agent until the
date the Agent recovers such amount at a rate per annum equal to (i) in the case of payment by a
Bank, the Federal Funds Rate for such day or (ii) in the case of payment by the Company, the
interest rate applicable to the relevant Loan.

ARTICLE III

LETTER OF CREDIT FACILITY

3.1 Issuance. Each LC Issuer hereby agrees, on the terms and conditions set forth in
this Agreement, to issue standby and commercial letters of credit denominated in U.S. dollars
(each, a “Facility LC”) and to renew, extend, increase, decrease or otherwise modify each
Facility LC (“Modify,” and each such action a “Modification”), from time to time
from and including the date hereof and prior to the Termination Date upon the request of the
Company; provided that immediately after each such Facility LC is issued or Modified, the Aggregate
Outstanding Credit Exposure shall not exceed the Available Commitment. No Facility LC shall (x) be
issued later than 30 days prior to the scheduled Termination Date, (y) have an expiry date later
than the fifth Business Day (or, in the case of a commercial Facility LC, the 30th day)
prior to the scheduled Termination Date or (z) provide for time drafts.

3.2 Participations. Upon the issuance or Modification by an LC Issuer of a Facility
LC in accordance with this Article III (or, in the case of any Existing Facility LC, on the
Initial Borrowing Date), such LC Issuer shall be deemed, without further action by any party
hereto, to have unconditionally and irrevocably sold to each Bank, and each Bank shall be deemed,
without further action by any party hereto, to have unconditionally and irrevocably purchased from
such LC Issuer, a participation in such Facility LC (and each Modification thereof) and the related
LC Obligations in proportion to its Pro Rata Share.

3.3 Notice. Subject to Section 3.1, the Company shall give the applicable LC
Issuer notice prior to 12:00 noon (New York time) at least three Business Days prior to the
proposed date of issuance (other than an Existing Facility LC) or Modification of each Facility LC,
specifying the beneficiary, the proposed date of issuance (or Modification) and the expiry date of
such Facility LC, and describing the proposed terms of such Facility LC and the nature of the
transactions proposed to be supported thereby. Upon receipt of such notice, the applicable LC
Issuer shall promptly notify the Agent, and the Agent shall promptly notify each Bank, of the
contents thereof and of the amount of such Bank’s participation in such proposed Facility LC. The
issuance or Modification by an LC Issuer of any Facility LC shall, in addition to the conditions
precedent set forth in Article XI (the satisfaction of which such LC Issuer shall have no
duty to ascertain), be subject to the conditions precedent that such Facility LC shall be
satisfactory to such LC Issuer and that the Company shall have executed and delivered such
application agreement and/or such other instruments and agreements relating to such Facility LC as
such LC Issuer shall have reasonably requested (each, a “Facility LC Application”). In the
event of any conflict between the terms of this Agreement and the terms of any Facility LC
Application, the terms of this Agreement shall control.

3.4 LC Fees. The Company shall pay to the Agent, for the account of the Banks ratably
in accordance with their respective Pro Rata Shares, a letter of credit fee (the “LC Fee”)
at a per annum rate equal to the Applicable Margin for Eurodollar Rate Loans in effect from time to
time on the daily undrawn stated amount of each Facility LC, such fee to be payable in arrears on
each Payment Date and the Termination Date (and, if applicable, thereafter on demand). The Company
shall also pay to each LC Issuer for its own account (a) a fronting fee for each Facility LC at the
time and in the amount (i) in the case of JPMorgan, set forth in the Fee Letter, and (ii) in the
case of any other LC Issuer, separately agreed by the Company and such LC Issuer, and (b)
documentary and processing charges in connection with the issuance or Modification of and draws
under Facility LCs in accordance with such LC Issuer’s standard schedule for such charges as in
effect from time to time.

3.5 Administration; Reimbursement by Banks. Upon receipt from the beneficiary of any
Facility LC of any demand for payment under such Facility LC, the applicable LC Issuer shall notify
the Agent and the Agent shall promptly notify the Company and each other Bank as to the amount to
be paid by such LC Issuer as a result of such demand and the proposed payment date (the “LC
Payment Date”). The responsibility of an LC Issuer to the Company and each Bank shall be only
to determine that the documents (including each demand for payment) delivered under each Facility
LC issued by such LC Issuer in connection with such presentment shall be in conformity in all
material respects with such Facility LC. Each LC Issuer shall endeavor to exercise the same care
in the issuance and administration of Facility LCs as it does with respect to letters of credit in
which no participations are granted, it being understood that in the absence of any gross
negligence or willful misconduct by such LC Issuer, each Bank shall be unconditionally and
irrevocably liable without regard to the occurrence of any Default or any condition precedent
whatsoever, to reimburse such LC Issuer on demand for (i) such Bank’s Pro Rata Share of the amount
of each payment made by such LC Issuer under each Facility LC issued by it to the extent such
amount is not reimbursed by the Company pursuant to Section 3.6 below, plus (ii) interest
on the foregoing amount to be reimbursed by such Bank, for each day from the date of such LC
Issuer’s demand for such Reimbursement (or, if such demand is made after 12:00 noon (New York time)
on such date, from the next succeeding Business Day) to the date on which such Bank pays the amount
to be reimbursed by it, at a rate of interest per annum equal to the Federal Funds Effective Rate
for the first three days and, thereafter, at a rate of interest equal to the rate applicable to
Floating Rate Advances.

3.6 Reimbursement by Company. The Company shall be irrevocably and unconditionally
obligated to reimburse the applicable LC Issuer on the applicable LC Payment Date for any amounts
to be paid by such LC Issuer upon any drawing under any Facility LC issued by it, without
presentment, demand, protest or other formalities of any kind; provided that neither the Company
nor any Bank shall hereby be precluded from asserting any claim for direct (but not consequential)
damages suffered by the Company or such Bank to the extent, but only to the extent, caused by (i)
the willful misconduct or gross negligence of such LC Issuer in determining whether a request
presented under any Facility LC issued by it complied with the terms of such Facility LC or (ii)
such LC Issuer’s failure to pay under any Facility LC issued by it after the presentation to it of
a request strictly complying with the terms and conditions of such Facility LC. All such amounts
paid by the applicable LC Issuer and remaining unpaid by the Company shall bear interest, payable
on demand, for each day until paid at a rate per annum equal to (x) the rate applicable to Floating
Rate Advances for such day if such day falls on or before the applicable LC Payment Date and (y)
the sum of 1% plus the rate applicable to Floating Rate Advances for such day if such day falls
after such LC Payment Date. The applicable LC Issuer will pay to each Bank ratably in accordance
with its Pro Rata Share all amounts received by such LC Issuer from the Company for application in
payment, in whole or in part, of the Reimbursement Obligation in respect of any Facility LC issued
by such LC Issuer, but only to the extent such Bank has made payment to such LC Issuer in respect
of such Facility LC pursuant to Section 3.5. Subject to the terms and conditions of this
Agreement (including the submission of a Borrowing Notice in compliance with Section 2.8
and the satisfaction of the applicable conditions precedent set forth in Article XI), the
Company may request an Advance hereunder for the purpose of satisfying any Reimbursement
Obligation.

3.7 Obligations Absolute. The Company’s obligations under this Article III
shall be absolute and unconditional under any and all circumstances and irrespective of any setoff,
counterclaim or defense to payment which the Company may have or have had against any LC Issuer,
any Bank or any beneficiary of a Facility LC. The Company further agrees with the LC Issuers and
the Banks that the LC Issuers and the Banks shall not be responsible for, and the Company’s
Reimbursement Obligation in respect of any Facility LC shall not be affected by, among other
things, the validity or genuineness of documents or of any endorsements thereon, even if such
documents should in fact prove to be in any or all respects invalid, fraudulent or forged, or any
dispute between or among the Company, any of its affiliates, the beneficiary of any Facility LC or
any financing institution or other party to whom any Facility LC may be transferred or any claims
or defenses whatsoever of the Company or of any of its affiliates against the beneficiary of any
Facility LC or any such transferee. No LC Issuer 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 Facility LC. The Company agrees that any action taken or
omitted by any LC Issuer or any Bank under or in connection with a Facility LC and the related
drafts and documents, if done without gross negligence or willful misconduct, shall be binding upon
the Company and shall not put any LC Issuer or any Bank under any liability to the Company.
Nothing in this Section 3.7 is intended to limit the right of the Company to make a claim
against any LC Issuer for damages as contemplated by the proviso to the first sentence of
Section 3.6.

3.8 Actions of LC Issuers. Each LC Issuer shall be entitled to rely, and shall be
fully protected in relying, upon any Facility LC, draft, writing, resolution, notice, consent,
certificate, affidavit, letter, cablegram, telegram, telecopy, telex or teletype message,
statement, order or other document 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, independent accountants and other experts selected by such LC Issuer. Each LC Issuer
shall be fully justified in failing or refusing to take any action under this Agreement unless it
shall first have received such advice or concurrence of the Majority Banks as it reasonably deems
appropriate or it shall first be indemnified to its reasonable satisfaction by the Banks against
any and all liability and expense which may be incurred by it by reason of taking or continuing to
take any such action. Notwithstanding any other provision of this Article III, each LC
Issuer shall in all cases be fully protected in acting, or in refraining from acting, under this
Agreement in accordance with a request of the Majority Banks, and such request and any action taken
or failure to act pursuant thereto shall be binding upon the Banks and any future holders of a
participation in any Facility LC.

3.9 Indemnification. The Company hereby agrees to indemnify and hold harmless each
Bank, each LC Issuer and the Agent, and their respective directors, officers, agents and employees
from and against any and all claims and damages, losses, liabilities, reasonable costs or expenses
which such Bank, such LC Issuer or the Agent may incur (or which may be claimed against such Bank,
such LC Issuer or the Agent by any Person whatsoever) by reason of or in connection with the
issuance, execution and delivery or transfer of or payment or failure to pay under any Facility LC
or any actual or proposed use of any Facility LC, including any claims, damages, losses,
liabilities, costs or expenses which any LC Issuer may incur by reason of or in connection with (i)
the failure of any other Bank to fulfill or comply with its obligations to such LC Issuer hereunder
(but nothing herein contained shall affect any rights the Company may have against any defaulting
Bank) or (ii) by reason of or on account of such LC Issuer issuing any Facility LC which specifies
that the term “Beneficiary” included therein includes any successor by operation of law of the
named Beneficiary, but which Facility LC does not require that any drawing by any such successor
Beneficiary be accompanied by a copy of a legal document, satisfactory to such LC Issuer,
evidencing the appointment of such successor Beneficiary; provided that the Company shall
not be required to indemnify any Bank, any LC Issuer or the Agent for any claims, damages, losses,
liabilities, costs or expenses to the extent, but only to the extent, caused by (x) the willful
misconduct or gross negligence of any LC Issuer in determining whether a request presented under
any Facility LC issued by it complied with the terms of such Facility LC or (y) any LC Issuer’s
failure to pay under any Facility LC issued by it after the presentation to it of a request
strictly complying with the terms and conditions of such Facility LC. Nothing in this Section
3.9 is intended to limit the obligations of the Company under any other provision of this
Agreement.

3.10 Banks’ Indemnification. Each Bank shall, ratably in accordance with its Pro Rata
Share, indemnify each LC Issuer, its affiliates and their respective directors, officers, agents
and employees (to the extent not reimbursed by the Company) against any cost, expense (including
reasonable counsel fees and disbursements), claim, demand, action, loss or liability (except such
as result from such indemnitees’ gross negligence or willful misconduct or such LC Issuer’s failure
to pay under any Facility LC issued by it after the presentation to it of a request strictly
complying with the terms and conditions of the Facility LC) that such indemnitees may suffer or
incur in connection with this Article III or any action taken or omitted by such indemnitees
hereunder.

3.11 Rights as a Bank. In its capacity as a Bank, each LC Issuer shall have the same
rights and obligations as any other Bank.

ARTICLE IV

CHANGE IN CIRCUMSTANCES

4.1 Yield Protection.

(a) If any change in law or any governmental rule, regulation, policy, guideline or directive
(whether or not having the force of law), or any interpretation thereof by any agency or authority
having jurisdiction over any Bank or any LC Issuer,

(i) subjects any Bank, any LC Issuer or any applicable Lending Installation to any
increased tax, duty, charge or withholding on or from payments due from the Company
(excluding taxation measured by or attributable to the overall net income of such Bank, such
LC Issuer or such applicable Lending Installation, whether overall or in any geographic
area), or changes the rate of taxation of payments to any Bank or any LC Issuer in respect
of its Credit Extensions (including any participations in Facility LCs) or other amounts due
it hereunder, or

(ii) imposes or increases or deems applicable any reserve, assessment, insurance
charge, special deposit or similar requirement against assets of, deposits with or for the
account of, or credit extended by any Bank, any LC Issuer or any applicable Lending
Installation (including any reserve costs under Regulation D with respect to Eurocurrency
liabilities (as defined in Regulation D)), or

(iii) imposes any other condition the result of which is to increase the cost to any
Bank, any LC Issuer or any applicable Lending Installation of making, funding or maintaining
Credit Extensions (including any participations in Facility LCs), or reduces any amount
receivable by any Bank, any LC Issuer or any applicable Lending Installation in connection
with Credit Extensions (including any participations in Facility LCs) or requires any Bank,
any LC Issuer or any applicable Lending Installation to make any payment calculated by
reference to its Outstanding Credit Exposure or interest received by it, by an amount deemed
material by such Bank or such LC Issuer, or

(iv) affects the amount of capital required or expected to be maintained by any Bank,
any LC Issuer or any applicable Lending Installation or any corporation controlling any Bank
or any LC Issuer and such Bank or such LC Issuer, as applicable, determines the amount of
capital required is increased by or based upon the existence of this Agreement or its
obligation to make Credit Extensions (including any participations in Facility LCs)
hereunder or of commitments of this type,

then, upon presentation by such Bank or such LC Issuer to the Company of a certificate (as referred
to in the immediately succeeding sentence of this Section 4.1) setting forth the basis for
such determination and the additional amounts reasonably determined by such Bank or such LC Issuer
for the period of up to 90 days prior to the date on which such certificate is delivered to the
Company and the Agent, to be sufficient to compensate such Bank or such LC Issuer, as applicable,
in light of such circumstances, the Company shall within 30 days of such delivery of such
certificate pay to the Agent for the account of such Bank or such LC Issuer, as applicable, the
specified amounts set forth on such certificate. The affected Bank or LC Issuer, as applicable,
shall deliver to the Company and the Agent a certificate setting forth the basis of the claim and
specifying in reasonable detail the calculation of such increased expense, which certificate shall
be prima facie evidence as to such increase and such amounts. An affected Bank or LC Issuer, as
applicable, may deliver more than one certificate to the Company during the term of this Agreement.
In making the determinations contemplated by the above-referenced certificate, any Bank and any LC
Issuer may make such reasonable estimates, assumptions, allocations and the like that such Bank or
such LC Issuer, as applicable, in good faith determines to be appropriate, and such Bank’s or such
LC Issuer’s selection thereof in accordance with this Section 4.1 shall be conclusive and
binding on the Company, absent manifest error.

(b) No LC Issuer or Bank shall be entitled to demand compensation or be compensated hereunder
to the extent that such compensation relates to any period of time more than 90 days prior to the
date upon which such Bank or such LC Issuer, as applicable, first notified the Company of the
occurrence of the event entitling such Bank or such LC Issuer, as applicable, to such compensation
(unless, and to the extent, that any such compensation so demanded shall relate to the retroactive
application of any event so notified to the Company).

4.2 Replacement Bank.

(a) If any Bank shall make a demand for payment under Section 4.1, then within 30 days
after such demand, the Company may, with the approval of the Agent (which approval shall not be
unreasonably withheld) and provided that no Default or Event of Default shall then have occurred
and be continuing, demand that such Bank assign to one or more financial institutions designated by
the Company and approved by the Agent all (but not less than all) of such Bank’s Commitment and
Outstanding Credit Exposure within the period ending on the later of such 30th day and the last day
of the longest of the then current Interest Periods or maturity dates for such Outstanding Credit
Exposure. Any such assignment shall be consummated on terms satisfactory to the assigning Bank;
provided that such Bank’s consent to such assignment shall not be unreasonably withheld.

(b) If the Company shall elect to replace a Bank pursuant to clause (a) above, the
Company shall prepay the Outstanding Credit Exposure of such Bank, and the financial institution or
institutions selected by the Company shall replace such Bank as a Bank hereunder pursuant to an
instrument satisfactory to the Company, the Agent and the Bank being replaced by making Credit
Extensions to the Company in the amount of the Outstanding Credit Exposure of such assigning Bank
and assuming all the same rights and responsibilities hereunder as such assigning Bank and having
the same Commitment as such assigning Bank.

4.3 Availability of Eurodollar Rate Loans. If

(a) any Bank determines that maintenance of a Eurodollar Rate Loan at a suitable Lending
Installation would violate any applicable law, rule, regulation or directive, whether or not having
the force of law, or

(b) the Majority Banks determine that (i) deposits of a type and maturity appropriate to match
fund Eurodollar Rate Loans are not available or (ii) the Base Eurodollar Rate does not accurately
reflect the cost of making or maintaining a Eurodollar Rate Loan,

then the Agent shall suspend the availability of Eurodollar Rate Loans and, in the case of
clause (a), require any outstanding Eurodollar Rate Loans to be converted to Floating Rate
Loans on such date as is required by the applicable law, rule, regulation or directive.

4.4 Funding Indemnification. If any payment of a Eurodollar Rate Loan occurs on a
date which is not the last day of an applicable Interest Period, whether because of prepayment or
otherwise, or a Eurodollar Rate Loan is not made on the date specified by the Company for any
reason other than default by the Banks, the Company will indemnify each Bank for any loss or cost
(but not lost profits) incurred by it resulting therefrom, including any loss or cost in
liquidating or employing deposits acquired to fund or maintain such Eurodollar Rate Loan;
provided that the Company shall not be liable for any of the foregoing to the extent they
arise because of acceleration by any Bank.

4.5

4

Taxes.

(a) All payments by the Company to or for the account of any Bank, any LC Issuer or the Agent
hereunder or under any Bond or Facility LC Application shall be made free and clear of and without
deduction for any and all Taxes. If the Company shall be required by law to deduct any Taxes from
or in respect of any sum payable hereunder to any Bank, any LC Issuer or the Agent, (i) the sum
payable shall be increased as necessary so that after making all required deductions (including
deductions applicable to additional sums payable under this Section 4.5) such Bank, such LC
Issuer or the 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 Company shall make such deductions, (iii) the Company
shall pay the full amount deducted to the relevant authority in accordance with applicable law and
(iv) the Company shall furnish to the Agent the original copy of a receipt evidencing payment
thereof within 30 days after such payment is made.

(b) In addition, the Company hereby agrees to pay any present or future stamp or documentary
taxes and any other excise or property taxes, charges or similar levies which arise from any
payment made hereunder or under any Bond or Facility LC Application or from the execution or
delivery of, or otherwise with respect to, this Agreement or any Bond or Facility LC Application
(“Other Taxes”).

(c) The Company hereby agrees to indemnify the Agent, each LC Issuer and each Bank for the
full amount of Taxes or Other Taxes (including any Taxes or Other Taxes imposed on amounts payable
under this Section 4.5) paid by the Agent, such LC Issuer or such Bank and any liability
(including penalties, interest and expenses) arising therefrom or with respect thereto. Payments
due under this indemnification shall be made within 30 days of the date the Agent, such LC Issuer
or such Bank makes demand therefor pursuant to Section 4.6.

(d) Each Bank that is not incorporated under the laws of the United States of America or a
state thereof (each a “Non-U.S. Bank”) agrees that it will, not more than ten Business Days
after the date hereof, or, if later, not more than ten Business Days after becoming a Bank
hereunder, (i) deliver to each of the Company and the Agent two duly completed copies of United
States Internal Revenue Service Form W-8BEN or W-8ECI, certifying in either case that such Bank is
entitled to receive payments under this Agreement without deduction or withholding of any United
States federal income taxes, and (ii) deliver to each of the Company and the Agent a United States
Internal Revenue Form W-8 or W-9, as the case may be, and certify that it is entitled to an
exemption from United States backup withholding tax. Each Non-U.S. Bank further undertakes to
deliver to each of the Company and the Agent (x) renewals or additional copies of such form (or any
successor form) on or before the date that such form expires or becomes obsolete, and (y) after the
occurrence of any event requiring a change in the most recent forms so delivered by it, such
additional forms or amendments thereto as may be reasonably requested by the Company or the Agent.
All forms or amendments described in the preceding sentence shall certify that such Bank is
entitled to receive payments under this Agreement without deduction or withholding of any United
States federal income taxes, unless an event (including any change in treaty, law or regulation)
has occurred prior to the date on which any such delivery would otherwise be required which renders
all such forms inapplicable or which would prevent such Bank from duly completing and delivering
any such form or amendment with respect to it and such Bank advises the Company and the Agent that
it is not capable of receiving payments without any deduction or withholding of United States
federal income tax.

(e) For any period during which a Non-U.S. Bank has failed to provide the Company with an
appropriate form pursuant to clause (d), above (unless such failure is due to a change in
treaty, law or regulation, or any change in the interpretation or administration thereof by any
governmental authority, occurring subsequent to the date on which a form originally was required to
be provided), such Non-U.S. Bank shall not be entitled to indemnification under this Section
4.5 with respect to Taxes imposed by the United States; provided that, should a
Non-U.S. Bank which is otherwise exempt from or subject to a reduced rate of withholding tax become
subject to Taxes because of its failure to deliver a form required under clause (d) above,
the Company shall take such steps as such Non-U.S. Bank shall reasonably request to assist such
Non-U.S. Bank to recover such Taxes.

(f) Any Bank that is entitled to an exemption from or reduction of withholding tax with
respect to payments under this Agreement or any Bond pursuant to the law of any relevant
jurisdiction or any treaty shall deliver to the Company (with a copy to the Agent), at the time or
times prescribed by applicable law, such properly completed and executed documentation prescribed
by applicable law as will permit such payments to be made without withholding or at a reduced rate.

(g) If the U.S. Internal Revenue Service or any other governmental authority of the United
States or any other country or any political subdivision thereof asserts a claim that the Agent did
not properly withhold tax from amounts paid to or for the account of any Bank (because the
appropriate form was not delivered or properly completed, because such Bank failed to notify the
Agent of a change in circumstances which rendered its exemption from withholding ineffective, or
for any other reason), such Bank shall indemnify the Agent fully for all amounts paid, directly or
indirectly, by the Agent as tax, withholding therefor, or otherwise, including penalties and
interest, and including taxes imposed by any jurisdiction on amounts payable to the Agent under
this clause (g), together with all costs and expenses related thereto (including attorneys
fees and time charges of attorneys for the Agent, which attorneys may be employees of the Agent).
The obligations of the Banks under this clause (g) shall survive the payment of the
Obligations and termination of this Agreement.

4.6 Bank Certificates, Survival of Indemnity. To the extent reasonably possible, each
Bank shall designate an alternate Lending Installation with respect to Eurodollar Rate Loans to
reduce any liability of the Company to such Bank under Section 4.1 or to avoid the
unavailability of Eurodollar Rate Loan under Section 4.3, so long as such designation is
not disadvantageous to such Bank. A certificate of such Bank as to the amount due under
Section 4.1, 4.4 or 4.5 shall be final, conclusive and binding on the
Company in the absence of manifest error. Determination of amounts payable under such Sections in
connection with a Eurodollar Rate Loan shall be calculated as though each Bank funded each
Eurodollar Rate Loan through the purchase of a deposit of the type and maturity corresponding to
the deposit used as a reference in determining the Base Eurodollar Rate applicable to such Loan
whether in fact that is the case or not. Unless otherwise provided herein, the amount specified in
any certificate shall be payable on demand after receipt by the Company of such certificate. The
obligations of the Company under Sections 4.1, 4.4 and 4.5 shall survive
payment of the Obligations and termination of this Agreement; provided that no Bank shall
be entitled to compensation to the extent that such compensation relates to any period of time more
than 90 days after the termination of this Agreement.

or suspended, whereupon the same shall forthwith terminate, and/or (ii) declare the Obligations to
be forthwith due and payable, whereupon the Aggregate Outstanding Credit Exposure and all other

act, pay to the Agent the Collateral Shortfall Amount (as defined below), which funds shall be
deposited in the Facility LC Collateral Account, in each case without presentment, demand, protest
or further notice of any kind, all of which are hereby expressly waived by the Company;
provided that in the case of an Event of Default referred to in Section 9.1(e), the
Commitments shall automatically terminate, the obligations and powers of the LC Issuers to issue
Facility LCs shall automatically terminate and the Obligations shall automatically become due and
payable without notice, presentment, demand, protest or other formalities of any kind, all of which
are hereby expressly waived by the Company, and the Company will be and become thereby
unconditionally obligated, without any further notice, act or demand, to pay to the Agent an amount
in immediately available funds, which funds shall be held in the Facility LC Collateral Account,
equal to the difference of (x) the amount of LC Obligations at such time, less (y) the amount on
deposit in the Facility LC Collateral Account at such time which is free and clear of all rights
and claims of third parties and has not been applied against the Obligations (such difference, the
“Collateral Shortfall Amount”).

(b) If at any time while any Event of Default is continuing, the Agent determines that the
Collateral Shortfall Amount at such time is greater than zero, the Agent may make demand on the
Company to pay, and the Company will, forthwith upon such demand and without any further notice or
act, pay to the Agent the Collateral Shortfall Amount, which funds shall be deposited in the
Facility LC Collateral Account.

(c) The Agent may, at any time or from time to time after funds are deposited in the Facility
LC Collateral Account, apply such funds to the payment of the Obligations and any other amounts as
shall from time to time have become due and payable by the Company to the Banks or the LC Issuers
under the Credit Documents. The Company hereby pledges, assigns and grants to the Agent, on behalf
of and for the ratable benefit of the Banks and the LC Issuers, a security interest in all of the
Company’s right, title and interest in and to all funds which may from time to time be on deposit
in the Facility LC Collateral Account to secure the prompt and complete payment and performance of
the Obligations. The Agent will invest any funds on deposit from time to time in the Facility LC
Collateral Account in certificates of deposit of JPMorgan having a maturity not exceeding 30 days.

(d) At any time while any Event of Default is continuing, neither the Company nor any Person
claiming on behalf of or through the Company shall have any right to withdraw any of the funds held
in the Facility LC Collateral Account. After all of the Obligations have been indefeasibly paid in
full, all Facility LCs have expired or been terminated and the Aggregate Commitment has been
terminated, any funds remaining in the Facility LC Collateral Account shall be returned by the
Agent to the Company or paid to whomever may be legally entitled thereto at such time.

into written agreements supplemental hereto for the purpose of adding or modifying any provisions
to the Credit Documents or changing in any manner the rights of the Banks or the Company hereunder
or waiving any Event of Default hereunder; provided that no such supplemental agreement
shall, without the consent of all of the Banks:

(a) Extend the maturity of any Loan or reduce the principal amount thereof, or extend the
expiry date of any Facility LC to a date after the scheduled Termination Date, or reduce the rate
or extend the time of payment of interest thereon or fees thereon or Reimbursement Obligations
related thereto.

(b) Modify the percentage specified in the definition of Majority Banks.

be effective without the written consent of such LC Issuer.

10.2 Preservation of Rights. No delay or omission of the Banks, the LC Issuers or the
Agent to exercise any right under the Credit Documents shall impair such right or be construed to
be a waiver of any Default or Event of Default or an acquiescence therein, and the making of a
Credit Extension notwithstanding the existence of a Default or Event of Default or the inability of
the Company to satisfy the conditions precedent to such Credit Extension shall not constitute any
waiver or acquiescence. Any single or partial exercise of any such right shall not preclude other
or further exercise thereof or the exercise of any other right, and no waiver, amendment or other
variation of the terms, conditions or provisions of the Credit Documents whatsoever shall be valid
unless in writing signed by the Banks required pursuant to Section 10.1, and then only to

any Loan or Commitment in which such Participant has an interest which would require consent of all
of the Banks pursuant to the terms of Section 10.1 or of any other Credit Document. The
Company agrees that each Participant shall be deemed to have the right of setoff provided in
Section 12.10 in respect of its participating interest in amounts owing under the Credit
Documents to the same extent as if the amount of its participating interest were owing directly to
it as a Bank under the Credit Documents; provided that each Bank shall retain the right of
setoff provided in Section 12.10 with respect to the amount of participating interests sold
to each Participant. The Banks agree to share with each Participant, and each Participant, by
exercising the right of setoff provided in Section 12.10, agrees to share with each Bank,
any amount received pursuant to the exercise of its right of setoff, such amounts to be shared in
accordance with Section 12.10 as if each Participant were a Bank. The Company further
agrees that each Participant shall be entitled to the benefits of Sections 4.1,
4.3, 4.4 and 4.5 to the same extent as if it were a Bank and had acquired
its interest by assignment pursuant to Section 12.1(c); provided that (i) a
Participant shall not be entitled to receive any greater payment under Section 4.1,
4.3, 4.4 or 4.5 than the Bank that sold the participating interest to such
Participant would have received had it retained such interest for its own account, unless the sale
of such interest to such Participant is made with the prior written consent of the Company, and
(ii) any Participant not incorporated under the laws of the United States of America or any State
thereof agrees to comply with the provisions of Section 4.5 to the same extent as if it
were a Bank.

(c) Any Bank may, in the ordinary course of its business and in accordance with applicable
law, at any time assign to one or more financial institutions or other Persons all or any part of
its rights and obligations under this Agreement; provided that (i) unless such assignment
is to another Bank, an affiliate of such assigning Bank or any direct or indirect contractual
counterparty in any swap agreement relating to the Loans to the extent required in connection with
the settlement of such Bank’s obligations pursuant thereto, such Bank has received the prior
written consent of the Agent, the Company (so long as no Event of Default exists) and each LC
Issuer, which consents of the Company and the LC Issuers shall not be unreasonably withheld or
delayed, and (ii) the minimum principal amount of any such assignment (other than assignments to a
Federal Reserve Bank, to another Bank, to an affiliate of such assigning Bank or to any direct or
indirect contractual counterparty in any swap agreement relating to the Loans to the extent
required in connection with the settlement of such Bank’s obligations pursuant thereto) shall be
$5,000,000 (or such lesser amount consented to by the Agent and, so long as no Event of Default
shall be continuing, the Company), which consents shall not be unreasonably withheld or delayed;
provided that after giving effect to such assignment the assigning Bank shall have a
Commitment of not less than $5,000,000 (unless otherwise consented to by the Agent and, so long as
no Event of Default shall be continuing, the Company). Notwithstanding the foregoing sentence, (x)
any Bank may at any time, without the consent of the Company or the Agent, assign all or any
portion of its rights under this Agreement to a Federal Reserve Bank; provided that no such
assignment shall release the transferor Bank from its obligations hereunder; and (y) no assignment
by a Bank shall release such Bank from its obligations hereunder unless (I) the Agent and, so long
as no Event of Default exists, the Company have approved such assignment or (II) the
creditworthiness of such affiliate (as determined in accordance with customary standards of the
banking industry) is no less than that of the assigning Bank.

(d) Any Bank may, in connection with any sale or participation or proposed sale or
participation pursuant to this Section 12.1, disclose to the purchaser or participant or
proposed purchaser or participant any information relating to the Company furnished to such Bank by
or on behalf of the Company; provided that prior to any such disclosure of non-public
information, the purchaser or participant or proposed purchaser or participant (which purchaser or
participant is not an affiliate of a Bank) shall agree to preserve the confidentiality of any
confidential information (except any such disclosure as may be required by law or regulatory
process) relating to the Company received by it from such Bank.

(e) Assignments under this Section 12.1 shall be made pursuant to an agreement (an
“Assignment Agreement”) substantially in the form of Exhibit D hereto or in such
other form as may be agreed to by the parties thereto and shall not be effective until a $3,500 fee
has been paid to the Agent by the assignee, which fee shall cover the cost of processing such
assignment; provided that such fee shall not be incurred in the event of an assignment by
any Bank of all or a portion of its rights under this Agreement to (i) a Federal Reserve Bank or
(ii) a Bank or an affiliate of the assigning Bank or (iii) to any direct or indirect contractual
counterparties in swap agreements relating to the Loans to the extent required in connection with
the settlement of any Bank’s obligations pursuant thereto.

12.2 Survival of Representations. All representations and warranties of the Company
contained in this Agreement shall survive the making of the Credit Extensions herein contemplated.

12.3 Governmental Regulation. Anything contained in this Agreement to the contrary
notwithstanding, no LC Issuer or Bank shall be obligated to extend credit to the Company in
violation of any limitation or prohibition provided by any applicable statute or regulation.

12.4 Taxes. Any taxes (excluding income taxes) payable or ruled payable by any
Federal or State authority in respect of the execution of the Credit Documents shall be paid by the
Company, together with interest and penalties, if any.

12.5 Choice of Law. THE CREDIT DOCUMENTS SHALL BE CONSTRUED IN ACCORDANCE WITH THE
INTERNAL LAWS (INCLUDING SECTION 5-1401 OF THE GENERAL OBLIGATIONS LAW OF NEW YORK, BUT OTHERWISE
WITHOUT REGARD TO THE LAW OF CONFLICTS) OF THE STATE OF NEW YORK, BUT GIVING EFFECT TO FEDERAL LAWS
APPLICABLE TO NATIONAL BANKS. THE COMPANY HEREBY IRREVOCABLY SUBMITS TO THE NON-EXCLUSIVE
JURISDICTION OF ANY UNITED STATES FEDERAL OR NEW YORK STATE COURT SITTING IN NEW YORK, NEW YORK IN
ANY ACTION OR PROCEEDING ARISING OUT OF OR RELATING TO ANY CREDIT DOCUMENT AND THE COMPANY HEREBY
IRREVOCABLY AGREES THAT ALL CLAIMS IN RESPECT OF ANY SUCH ACTION OR PROCEEDING MAY BE HEARD AND
DETERMINED IN ANY SUCH COURT. THE COMPANY HEREBY WAIVES ANY RIGHT TO A JURY TRIAL IN ANY ACTION OR
ARISING HEREUNDER OR UNDER ANY CREDIT DOCUMENT.

12.6 Headings. Section headings in the Credit Documents are for convenience of
reference only, and shall not govern the interpretation of any of the provisions of the Credit
Documents.

12.7 Entire Agreement. The Credit Documents embody the entire agreement and
understanding between the Company, the LC Issuers, the Agent and the Banks and supersede all prior
agreements and understandings between the Company, the LC Issuers, the Agent and the Banks relating
to the subject matter thereof (other than those contained in the Fee Letter which shall survive and
remain in full force and effect during the term of this Agreement).

12.8 Expenses; Indemnification. The Company shall reimburse the Agent and each
Arranger for (a) any reasonable costs, internal charges and out-of-pocket expenses (including
reasonable attorneys’ fees and time charges of attorneys for the Agent) paid or incurred by the
Agent or such Arranger in connection with the preparation, review, execution, delivery,
syndication, distribution (including via the internet), amendment and modification of the Credit
Documents and (b) any reasonable costs, internal charges and out-of-pocket expenses (including
reasonable attorneys’ fees and time charges of attorneys for the Agent) paid or incurred by the
Agent or such Arranger on its own behalf or on behalf of any LC Issuer or any Bank and, on or after
the date upon which an Event of Default specified in Section 9.1(a) or 9.1(e) has
occurred and is continuing, each Bank, in connection with the collection and enforcement of the
Credit Documents. The Company further agrees to indemnify the Agent, each Arranger, each LC
Issuer, each Bank and their respective Affiliates, and the directors, officers, employees and
agents of the foregoing (all of the foregoing, the “Indemnified Persons), against all losses,
claims, damages, penalties, judgments, liabilities and reasonable expenses (including all
reasonable expenses of litigation or preparation therefor whether or not an Indemnified Person is a
party thereto) which any of them may pay or incur arising out of or relating to this Agreement, the
other Credit Documents, the transactions contemplated hereby, the direct or indirect application or
proposed application of the proceeds of any Credit Extension hereunder, any actual or alleged
presence or release of any Hazardous Substance on or from any property owned or operated by the
Company or any Subsidiary or any Environmental Liability related in any way to the Company or any
Subsidiary; provided that the Company shall not be liable to any Indemnified Person for any
of the foregoing to the extent they arise from the gross negligence or willful misconduct of such
Indemnified Person. Without limiting the foregoing, the Company shall pay any civil penalty or
fine assessed by the Office of Foreign Assets Control against any Indemnified Person, and all
reasonable costs and expenses (including reasonable fees and expenses of counsel to such
Indemnified Person) incurred in connection with defense thereof, as a result of any breach or
inaccuracy of the representation made in Section 5.14. The obligations of the Company
under this Section shall survive the termination of this Agreement.

12.9 Severability of Provisions. Any provision in any Credit Document that is held to
be inoperative, unenforceable or invalid in any jurisdiction shall, as to that jurisdiction, be
inoperative, unenforceable or invalid without affecting the remaining provisions in that
jurisdiction or the operation, enforceability or validity of that provision in any other
jurisdiction, and to this end the provisions of all Credit Documents are declared to be severable.

12.10 Setoff. In addition to, and without limitation of, any rights of the Banks
under applicable law, if the Company becomes insolvent, however evidenced, or any Default or Event
of Default occurs, any indebtedness from any Bank or any of its Affiliates to the Company
(including all account balances, whether provisional or final and whether or not collected or
available) may be offset and applied toward the payment of the Obligations owing to such Bank or
such Affiliate, whether or not the Obligations, or any part hereof, shall then be due. The Company
agrees that any purchaser or participant under Section 12.1 may, to the fullest extent
permitted by law, exercise all its rights of payment with respect to such purchase or participation
as if it were the direct creditor of the Company in the amount of such purchase or participation.

12.11 Ratable Payments. If any Bank, whether by setoff or otherwise, has payment made
to it upon its Outstanding Credit Exposure in a greater proportion than that received by any other
Bank, such Bank agrees, promptly upon demand, to purchase a portion of the Aggregate Outstanding
Credit Exposure held by the other Banks so that after such purchase each Bank will hold its Pro
Rata Share of the Aggregate Outstanding Credit Exposure. If any Bank, whether in connection with
setoff or amounts which might be subject to setoff or otherwise, receives collateral or other
protection for its Obligations or such amounts which may be subject to setoff, such Bank agrees,
promptly upon demand, to take such action necessary such that all Banks share in the benefits of
such collateral ratably in proportion to their respective Pro Rata Share of the Aggregate
Outstanding Credit Exposure. In case any such payment is disturbed by legal process, or otherwise,
appropriate further adjustments shall be made.

12.12 Nonliability. The relationship between the Company, on the one hand, and the
Banks, the Arrangers, the LC Issuers and the Agent, on the other hand, shall be solely that of
borrower and lender. None of the Agent, either Arranger, any LC Issuer or any Bank shall have any
fiduciary responsibilities to the Company. None of the Agent, either Arranger, any LC Issuer or
any Bank undertakes any responsibility to the Company to review or inform the Company of any matter
in connection with any phase of the Company’s business or operations. The Company shall rely
entirely upon its own judgment with respect to its business, and any review, inspection,
supervision or information supplied to the Company by the Banks is for the protection of the Banks
and neither the Company nor any third party is entitled to rely thereon. The Company agrees that
none of the Agent, either Arranger, any LC Issuer or any Bank shall have liability to the Company
(whether sounding in tort, contract or otherwise) for losses suffered by the Company in connection
with, arising out of, or in any way related to, the transactions contemplated and the relationship
established by the Credit Documents, or any act, omission or event occurring in connection
therewith, unless it is determined in a final non-appealable judgment by a court of competent
jurisdiction that such losses resulted from the gross negligence or willful misconduct of the party
from which recovery is sought. None of the Agent, either Arranger, any LC Issuer or any Bank shall
have any liability with respect to, and the Company hereby waives, releases and agrees not to sue
for, any special, indirect, consequential or punitive damages suffered by the Company in connection
with, arising out of, or in any way related to the Credit Documents or the transactions
contemplated thereby.

12.13 Other Agents. The Banks identified on the signature pages of this Agreement or
otherwise herein, or in any amendment hereof or other document related hereto, as being the
“Syndication Agent” or a Co-Documentation Agent (the “Other Agents”) shall have no rights,
powers, obligations, liabilities, responsibilities or duties under this Agreement other than those
applicable to all Banks as such. Without limiting the foregoing, the Other Agents shall not 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 the Other Agents in deciding to enter into this Agreement or in
taking or refraining from taking any action hereunder or pursuant hereto.

12.14 USA Patriot Act. Each Bank hereby notifies the Company that pursuant to
requirements of the USA Patriot Act, such Bank is required to obtain, verify and record information
that identifies the Company, which information includes the name and address of the Company and
other information that will allow such Bank to identify the Company in accordance with the USA
Patriot Act.

12.15 Electronic Delivery.

(a) The Company shall use its commercially reasonable best efforts to transmit to the Agent
all information, documents and other materials that it is obligated to furnish to the Agent
pursuant to this Agreement and the other Credit Documents, including all notices, requests,
financial statements, financial and other reports, certificates and other information materials,
but excluding (i) any Borrowing Notice, Conversion/Continuation Notice or notice of prepayment,
(ii) any notice of a Default or an Event of Default or (iii) any communication that is required to
be delivered to satisfy any condition precedent to the effectiveness of this Agreement and/or any
Advance hereunder (all such non-excluded communications, collectively, “Communications”),
in an electronic/soft medium in a format reasonably acceptable to the Agent to such e-mail address
as designated by the Agent from time to time. In addition, the Company shall continue to provide
Communications to the Agent or any Bank in the manner specified in this Agreement but only to the
extent requested by the Agent or such Bank. Each Bank and the Company further agrees that the
Agent may make Communications available to the Banks by posting Communications on IntraLinks or a
substantially similar electronic transmission system (the “Platform”); provided,
that upon written notice to the Agent and the Company, any Bank (such bank, a “Declining
Bank”) may decline to receive Communications via the Platform and shall direct the Company to
provide, and the Company shall so provide, such Communications to such Declining Bank by delivery
to such Declining Bank’s address in accordance with Section 14.1. Subject to the
conditions set forth in the proviso in the immediately preceding sentence, nothing in this
Section 12.15 shall prejudice the right of the Agent to make Communications available to
the Banks in any other manner specified herein.

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

(c) Each party hereto (other than a Declining Bank) agrees that any electronic Communication
referred to in this Section 12.15 shall be deemed delivered upon the posting of a record of
such Communication as “sent” in the e-mail system of the sending party or, in the case of any such
Communication to the Agent, upon the posting of a record of such Communication as “received” in the
e-mail system of the Agent, provided that if such Communication is not so received by a
Person during the normal business hours of such Person, such Communication shall be deemed
delivered at the opening of business on the next business day for such Person.

(d) Each party hereto acknowledges that the distribution of material through an electronic
medium is not necessarily secure and there are confidentiality and other risks associated with such
distribution.

(e) EACH PARTY HERETO FURTHER ACKNOWLEDGES AND AGREES THAT:

(i) NONE OF THE AGENT OR ITS AFFILIATES OR ANY OF THEIR RESPECTIVE OFFICERS, DIRECTORS,
EMPLOYEES, AGENTS, ADVISORS OR REPRESENTATIVES (COLLECTIVELY, THE “AGENT PARTIES”)
WARRANTS THE ADEQUACY OF THE PLATFORM OR THE ACCURACY OR COMPLETENESS OF ANY COMMUNICATION,
AND EACH AGENT PARTY EXPRESSLY DISCLAIMS LIABILITY FOR ERRORS OR OMISSIONS IN ANY
COMMUNICATION; AND

(ii) NO WARRANTY OF ANY KIND, EXPRESS, IMPLIED OR STATUTORY, INCLUDING ANY WARRANTY OF
MERCHANTABILITY, FITNESS FOR A PARTICULAR PURPOSE, NON-INFRINGEMENT OF THIRD PARTY RIGHTS OR
FREEDOM FROM VIRUSES OR OTHER CODE DEFECTS, IS MADE BY ANY AGENT PARTY IN CONNECTION WITH
ANY COMMUNICATION OR THE PLATFORM.

thereto shall be binding on all of the Banks. The Banks hereby acknowledge that the Agent shall be
under no duty to take any discretionary action permitted to be taken by it pursuant to the
provisions of this Agreement or any other Credit Document unless it shall be requested in writing
to do so by the Majority Banks. The Agent shall be fully justified in failing or refusing to take

13.8 Agent’s Reimbursement and Indemnification. The Banks agree to reimburse and
indemnify the Agent ratably in accordance with their respective Pro Rata Shares (i) for any amounts
not reimbursed by the Company for which the Agent is entitled to reimbursement by the Company under

of this Agreement or any other document delivered in connection with this Agreement or the
transactions contemplated hereby or the enforcement of any of the terms hereof or of any such other
documents, and for which the Agent is not entitled to reimbursement by the Company under the Credit
Documents; provided that no Bank shall be liable for any of the foregoing to the extent
they arise from the gross negligence or willful misconduct of the Agent.

13.9 Rights as a Bank. With respect to its Commitment and any Credit Extension made
by it, the Agent shall have the same rights and powers hereunder as any Bank and may exercise the
same as though it were not the Agent, and the term “Bank” or “Banks” shall, unless the context

decisions in taking or not taking action under this Agreement.

(b) Without limiting clause (a) above, each Bank acknowledges and agrees that neither
such Bank nor any of its Affiliates, participants or assignees may rely on the Agent to carry out
such Bank’s or other Person’s customer identification program, or other obligations required or
imposed under or pursuant to the USA Patriot Act or the regulations thereunder, including the
regulations contained in 31 C.F.R. 103.121 (as amended or replaced, the “CIP Regulations”),

hereby: (i) any identity verification procedure; (ii) any recordkeeping; (iii) any comparison with

regulations because it is both (i) an affiliate of a depository institution or foreign bank that

supervision by a banking authority regulating such affiliated depository institution or foreign
bank) shall deliver to the Agent a certification, or, if applicable, recertification, certifying

the USA Patriot Act and the applicable regulations.

13.11 Successor Agent. The Agent may resign at any time by giving written notice
thereof to the Banks and the Company, and the Agent may be removed at any time with or without
cause by written notice received by the Agent from the Majority Banks. Upon any such resignation
or removal, the Majority Banks shall have the right to appoint, on behalf of the Banks, a successor
Agent. If no successor Agent shall have been so appointed by the Majority Banks and shall have
accepted such appointment within thirty days after the retiring Agent’s giving notice of
resignation, then the retiring Agent may appoint, on behalf of the Banks, a successor Agent. Such
successor Agent shall be a commercial bank having capital and retained earnings of at least
$500,000,000. Upon the acceptance of any appointment as Agent hereunder by a successor Agent, such
successor Agent shall thereupon succeed to and become vested with all the rights, powers,
privileges and duties of the retiring Agent, and the retiring Agent shall be discharged from its
duties and obligations hereunder. After any retiring Agent’s resignation hereunder as Agent, the
provisions of this Article XIII shall continue in effect for its benefit in respect of any
actions taken or omitted to be taken by it while it was acting as the Agent hereunder.

13.12 Agent and Arranger Fees. The Company agrees to pay to the Agent, J.P. Morgan
Securities Inc. (“JPMSI”) and Barclays Capital (“Barclays”; together with JPMSI, the “Arrangers”),

ARTICLE XV

TERMINATION OF PRIOR AGREEMENT

The Company and the Banks which are parties to the Prior Agreement (which Banks constitute
“Majority Banks” under the Prior Agreement) agree that notwithstanding any requirement for notice
of termination of the Commitments under Section 2.5(b) of the Prior Agreement), simultaneously with

calculated exclusive of (i) all debt of any Affiliate of the Borrower (other than a Subsidiary)

Financial Accounting Standards No. 94, and (B) non-recourse to the Borrower or any Subsidiary, (ii)

interpretation, bulletin or other similar document by the Financial Accounting Standards Board on
or related to such re-categorization and (iii) other amounts attributable to the disposition of the

Standards dated March 31, 2006: Employers’ Accounting for Defined Pension and other Postretirement

Off-Balance Sheet Liabilities, including, but not limited to, the application of Financial
Accounting Standards Board Interpretation Nos. 45 and 46 and Financial Accounting Standards Board
Statement No. 150, in each case, with the agreement of its independent certified public
accountants, and such changes result in a change in the method of calculation or the results of any
of the financial covenants, tests, restrictions or standards herein or in the related definitions
or terms used therein (“Accounting Changes”), the parties hereto agree, at the Borrower’s request,
to enter into negotiations, in good faith, in order to amend such provisions in a credit neutral
manner so as to reflect equitably such changes with the desired result that the criteria for
evaluating the Borrower’s and its Subsidiaries’ financial condition shall be the same after such
changes as if such changes had not been made; provided, however, until such provisions are amended
in a manner reasonably satisfactory to the Administrative Agent and the Required Lenders, no
Accounting Change shall be given effect in such calculations. In the event such amendment is
entered into, all references in this Agreement to GAAP means generally accepted accounting
principles as of the date of such amendment. Notwithstanding the foregoing, all financial
statements to be delivered by the Borrower pursuant to Section 8.03 shall be prepared in accordance
with generally accepted accounting principles in effect at such time.

Credit hereunder, prepay Loans or reduce or cancel Letters of Credit, and use the resulting
increase in the Available Commitments for further Extensions of Credit in accordance with the terms
hereof.

SECTION 2.02. Fees.

(a) The Borrower agrees to pay to the Administrative Agent for the account of each Lender,
from the Closing Date until the date on which the Commitments shall be terminated in whole, a
commitment fee equal to the product of (i) the average daily amount of such Lender’s Available
Commitment from time to time multiplied by (ii) the Commitment Fee Rate. Such fees shall be
payable quarterly in arrears on the last day of each March, June, September and December,
commencing the first such date to occur following the Closing Date, and on the Commitment
Termination Date.

(b) In addition to the fees provided for in subsection (a) above, the Borrower shall pay to
the Administrative Agent and/or the Arrangers, as the case may be, the fees set forth in (i) that
certain letter agreement, dated March 1, 2007 among the Borrower, the Administrative Agent, the
Arrangers and the other parties thereto and (ii) that certain letter agreement, dated March 1,
2007, among the Borrower, the Administrative Agent and the other parties thereto (collectively, the
“Fee Letters”), in the amounts and at the times specified therein.

Lenders, a letter of credit fee on the daily aggregate amount of the LC Outstandings at a rate per

Administrative Agent not later than 10:00 a.m. (New York City time) on the date of termination or
reduction, and the Administrative Agent shall promptly distribute copies thereof to the Lenders)
terminate in whole or reduce ratably in part the unused portions of the Commitments; provided that
any such partial reduction shall be in the aggregate amount of $5,000,000 or an integral multiple
of $1,000,000 in excess thereof.

(b) Change of Control. Upon the occurrence of a Change of Control the Commitments shall be
reduced to zero, the principal amount outstanding hereunder, all interest thereon and all other
amounts payable under this Agreement and the other Loan Documents shall become and be forthwith due
and payable and all of the LC Obligations shall be cash collateralized in accordance with the terms
of Section 9.02, in each case without presentment, demand, protest or further notice of any kind,
all of which are hereby expressly waived by the Borrower.

(c) Prepayment upon Issuance or Sale of Consumers Stock. The Borrower shall make a mandatory
prepayment promptly and in any event within 3 Business Days after the Borrower’s receipt of any Net
Proceeds from the issuance, sale, assignment or other disposition of any capital stock or other

together with (i) accrued interest to the date of such prepayment on the principal amount prepaid
and (ii) in the case of Eurodollar Rate Loans, any amount payable to the Lenders pursuant to
Section 5.04(b), and the Commitments shall be reduced, pro rata, in an aggregate amount equal to
such Net Proceeds. Nothing in this Section 2.03(c) shall be construed to constitute the Lenders’
consent to any transaction referenced in this clause (c) which is not expressly permitted by
Article VIII. The Borrower shall give the Administrative Agent prior written notice or telephonic
notice promptly confirmed in writing (each of which the Administrative Agent shall promptly
transmit to each Lender) of when a prepayment required by this Section 2.03(c) will be made (which
date of prepayment shall be no later than the date on which such prepayment becomes due and payable
pursuant to this Section 2.03(c)). All such prepayments shall be applied first to repay
outstanding ABR Loans, then to repay outstanding Eurodollar Rate Loans with those Eurodollar Rate
Loans which have earlier expiring Interest Periods being repaid prior to those which have later
expiring Interest Periods and then as cash collateral pursuant to the Cash Collateral Agreement, to
secure LC Outstandings.

(d) Increase of Commitments; Additional Lenders. The Borrower shall have the right, upon at
least five (5) Business Days’ notice to the Administrative Agent, to add one or more Eligible Banks

the Commitment of an existing Lender upon the request of the Borrower pursuant to this Section
2.03(d) being referred to as a “Lender Addition”); provided that (i) each such proposed
Lender, in the case of an Eligible Bank not already a Lender hereunder, is acceptable to the
Administrative Agent (the consent of the Administrative Agent not to be unreasonably withheld);
(ii) the amount of all increases to the Commitments made pursuant to this Section 2.03(d) on any
Business Day shall be equal to or greater than $25,000,000 in the aggregate; and (iii) the amount
of all increases to the Commitments made pursuant to this Section 2.03(d) during the term of this
Agreement shall not exceed $250,000,000 in the aggregate. Each notice of a proposed Lender
Addition (a “Notice of Lender Addition”) shall be by telecopy, confirmed immediately in writing, in
substantially the form of Exhibit K hereto, specifying therein (i) the name and address of the
proposed Added Lender, (ii) the date on which the Borrower wishes such Lender Addition to become
effective, and (iii) the amount of the Commitment such Added Lender would have hereunder after
giving effect to such Lender Addition. If the conditions set forth in the proviso contained in the
first sentence of this Section 2.03(d) have been satisfied, the Administrative Agent shall forward
to such Added Lender and the Borrower for execution by such Added Lender and the Borrower an
Assumption and Acceptance. The Added Bank shall, upon such execution, return the executed
Assumption and Acceptance to the Administrative Agent, for the Administrative Agent’s acceptance
thereof.

Upon such execution, delivery and acceptance, from and after the effective date specified in
each Assumption and Acceptance, the Added Lender shall, in addition to the rights and obligations
hereunder held by it immediately prior to such effective date (if any), have the rights and
obligations hereunder that have been assumed by it pursuant to such Assumption and Acceptance and,
in the case of an Eligible Bank not previously a Lender hereunder, shall become a Lender hereunder.

By executing and delivering an Assumption and Acceptance, each Added Lender confirms to and
agrees with each party hereto as follows: (i) neither the Administrative Agent nor any Lender
makes any representation or warranty, nor assumes any responsibility with respect to, any
statements, warranties or representations made in or in connection with this Agreement or the
execution, legality, validity, enforceability, genuineness, sufficiency or value of this Agreement
or any other instrument or document furnished pursuant hereto; and (ii) neither the Administrative
Agent nor any Lender makes any representation or warranty, nor assumes any responsibility with
respect to, the financial condition of the Borrower or the performance or observance by the
Borrower of any of its obligations under this Agreement or any other instrument or document
furnished pursuant hereto.

Upon its receipt of an Assumption and Acceptance executed by an Added Lender and the Borrower,
the Administrative Agent shall, if such Assumption and Acceptance has been completed and is in
substantially the form of Exhibit L hereto, (i) accept such Assumption and Acceptance, and (ii)
give prompt notice thereof to the Borrower. If requested by an Added Lender, the Borrower, at its
own expense, shall execute and deliver to the Administrative Agent a new Promissory Note or
Promissory Notes to the order of such Added Lender in accordance with Section 3.01(c). Such new
Promissory Note or Promissory Notes shall be dated the effective date of such Assumption and
Acceptance.

(e) Reallocation Upon Lender Addition. If there are any Borrowings outstanding on the
effective date of any Assumption and Acceptance, the Added Lender shall purchase from the other
Lenders such participations in such Borrowings as shall be necessary to cause such Added Lender to
share ratably (based on the proportion that such Added Lender’s Commitment bears to the total
Commitments after giving effect to the Lender Addition) in each such Borrowing. To purchase such
participations, the Added Lender shall before 12:00 noon (New York City time) on the effective date
of its Assumption and Acceptance, make available for the account of its Applicable Lending Office
to the Agent at its address referred to in Section 11.02, in Dollars and in same day funds,
such Added Lender’s ratable portion (based on the proportion that such Added Lender’s Commitment
(or the increase in such Added Lender’s Commitment, in the case of an Added Lender which is an
existing Lender hereunder) bears to the total Commitments after giving effect to the Lender
Addition) of each Borrowing then outstanding, together with an amount equal to such ratable portion
of the interest which has accrued to such date and remains unpaid on such Borrowing. After the
Agent’s receipt of such funds, the Agent will promptly make such same day funds available to the
account of each Lender in an amount equal to such Lender’s ratable portion of such payment by the
Added Lender.

SECTION 2.04. Computations of Outstandings. Whenever reference is made in this Agreement to
the principal amount outstanding on any date under this Agreement, such reference shall refer to
the Total Outstandings. References to the unused portion of the Commitments shall refer to the
excess, if any, of the Commitments hereunder over the Total Outstandings; and references to the
unused portion of any Lender’s Commitment shall refer to such Lender’s Percentage of the unused
Commitments.

LOANS

(a) The Borrower may request a Borrowing (other than a Conversion) by delivering a notice (a
“Notice of Borrowing”) to the Administrative Agent no later than 12:00 noon (New York City time) on
the third Business Day prior to the proposed Borrowing or, in the case of ABR Loans, no later than
11:00 a.m. (New York City time) on the date of the proposed Borrowing. The Administrative Agent
shall give each Lender prompt notice of each Notice of Borrowing. Each Notice of Borrowing shall
be in substantially the form of Exhibit A and shall specify the requested (i) date of such
Borrowing, (ii) Type of Loans to be made in connection with such Borrowing, (iii) Interest Period,
if any, for such Loans and (iv) amount of such Borrowing. Each proposed Borrowing shall conform to
the requirements of Sections 3.03 and 3.04.

(b) Each Lender shall, before 1:00 p.m. (New York City time) on the date of such Borrowing,
make available for the account of its Applicable Lending Office to the Administrative Agent at the
Administrative Agent’s offices at 2 Penns Way, Suite 200, New Castle, DE 19270, in same day funds,
such Lender’s Percentage of such Borrowing. After the Administrative Agent’s receipt of such funds
and upon fulfillment of the applicable conditions set forth in Article VI, the Administrative Agent
will make such funds available to the Borrower at the Administrative Agent’s aforesaid address.
Notwithstanding the foregoing, unless the Administrative Agent shall have received notice from a
Lender prior to the date of any Borrowing that such Lender will not make available to the
Administrative Agent such Lender’s Percentage of such Borrowing, the Administrative Agent may
assume that such Lender has made such Percentage available to the Administrative Agent on the date
of such Borrowing in accordance with the first sentence of this subsection (b), and the
Administrative Agent may, in reliance upon such assumption, make available to the Borrower on such
date a corresponding amount.

(c) The Extensions of Credit made by each Lender shall be evidenced by one or more accounts or
records maintained by such Lender and by the Administrative Agent in the ordinary course of
business. The accounts or records maintained by the Administrative Agent and each Lender shall be
conclusive absent manifest error of the amount of the Extensions of Credit made by the Lenders to
the Borrower and the interest and payments thereon. Any failure to so record or any error in doing
so shall not, however, limit or otherwise affect the obligation of the Borrower hereunder to pay
any amount owing with respect to the Obligations. In the event of any conflict between the
accounts and records maintained by any Lender and the accounts and records of the Administrative
Agent in respect of such matters, the accounts and records of the Administrative Agent shall
control in the absence of manifest error. Any Lender may request that Loans made by it be
evidenced by a Promissory Note. In such event, the Borrower shall prepare, execute and deliver to
such Lender a Promissory Note payable to the order of such Lender (or, if requested by such Lender,
to such Lender and its registered assigns) and in a form approved by the Administrative Agent.
Thereafter, the Loans evidenced by such Promissory Note and interest thereon shall at all times
(including after assignment pursuant to Section 11.07) be represented by one or more Promissory
Notes in such form payable to the order of the payee named therein, except to the extent that any
such Lender subsequently returns any such Promissory Note for cancellation and requests that such
Loans once again be evidenced as described in the first sentence of this Section 3.01(c).

SECTION 3.02. Conversion of Loans. The Borrower may from time to time Convert any of the
Loans (or portions thereof) of any Type to one or more Loans of the same or any other Type by
delivering a notice of such Conversion (a “Notice of Conversion”) to the Administrative Agent (x)
no later than 12:00 noon (New York City time) on the third Business Day prior to the date of any
proposed Conversion into a Eurodollar Rate Loan and (y) no later than 11:00 a.m. (New York City
time) on the date of any proposed Conversion into an ABR Loan. The Administrative Agent shall give
each Lender prompt notice of each Notice of Conversion. Each Notice of Conversion shall be in
substantially the form of Exhibit B and shall specify (i) the requested date of such Conversion,
(ii) the Type of, and Interest Period, if any, applicable to, the Loans (or portions thereof)
proposed to be Converted, (iii) the requested Type of Loans to which such Loans (or portions
thereof) are proposed to be Converted, (iv) the requested initial Interest Period, if any, to be
applicable to the Loans resulting from such Conversion and (v) the aggregate amount of Loans (or
portions thereof) proposed to be Converted. Each proposed Conversion shall be subject to the
provisions of Sections 3.03 and 3.04.

SECTION 3.03. Interest Periods. The period between the date of each Eurodollar Rate Loan and
the date of payment in full of such Loan shall be divided into successive periods of months
(“Interest Periods”) for purposes of computing interest applicable thereto. The initial Interest
Period for each such Loan shall begin on the day such Loan is made, and each subsequent Interest
Period shall begin on the last day of the immediately preceding Interest Period for such Loan. The
duration of each Interest Period shall be 1, 2, 3, or 6 months, as the Borrower may, in accordance
with Section 3.01 or 3.02, select; provided, however, that:

(i) the Borrower may not select any Interest Period for a Eurodollar Rate Loan that
ends after the Maturity Date;

(ii) whenever the last day of any Interest Period would otherwise occur on a day other
than a Business Day, the last day of such Interest Period shall occur on the next succeeding
Business Day, provided that if such extension would cause the last day of such Interest
Period to occur in the next following calendar month, the last day of such Interest Period
shall occur on the next preceding Business Day; and

(iii) any Interest Period that commences on the last Business Day of a calendar month
(or on a day for which there is no numerically corresponding day in the last calendar month
of such Interest Period) shall end on the last Business Day of the last calendar month of
such Interest Period.

SECTION 3.04. Other Terms Relating to the Making and Conversion of Loans.

(a) Notwithstanding anything in Section 3.01 or 3.02 to the contrary:

(i) each Borrowing shall be in an aggregate amount not less than $5,000,000, or an
integral multiple of $1,000,000 in excess thereof (or such lesser amount as shall be equal
to the total amount of the Available Commitments on such date, after giving effect to all
other Extensions of Credit to be made on such date), and shall consist of Loans to the same
Borrower of the same Type, having the same Interest Period and made or Converted on the same
day by the Lenders ratably according to their respective Percentages;

(ii) at no time shall the number of Borrowings comprising Eurodollar Rate Loans
outstanding hereunder be greater than ten (10);

(iii) no Eurodollar Rate Loan may be Converted on a date other than the last day of the
Interest Period applicable to such Loan unless the corresponding amounts, if any, payable to
the Lenders pursuant to Section 5.04(b) are paid contemporaneously with such Conversion;

(iv) if the Borrower shall either fail to give a timely Notice of Conversion pursuant
to Section 3.02 in respect of any of the Loans or fail, in any Notice of Conversion that has
been timely given, to select the duration of any Interest Period for any of the Loans to be
Converted into Eurodollar Rate Loans in accordance with Section 3.03, such Loans shall, on
the last day of the then existing Interest Period therefor, automatically Convert into, or
remain as, as the case may be, ABR Loans; and

(v) if, on the date of any proposed Conversion, any Event of Default or Default shall
have occurred and be continuing, all Loans then outstanding shall, on such date,
automatically Convert into, or remain as, as the case may be, ABR Loans.

(b) If any Lender shall notify the Administrative Agent that the introduction of or any change
in or in the interpretation of any law or regulation makes it unlawful, or that any central bank or
other governmental authority asserts that it is unlawful, for such Lender or its Applicable Lending
Office to perform its obligations hereunder to make, or to fund or maintain, Eurodollar Rate Loans
hereunder, (i) the obligation of such Lender to make, or to Convert Loans into, Eurodollar Rate
Loans for any Borrowing from such Lender shall be forthwith suspended until the earlier to occur of
the date upon which (A) such Lender shall cease to be a party hereto and (B) it is no longer
unlawful for such Lender to make, fund or maintain Eurodollar Rate Loans, and (ii) if the
maintenance of Eurodollar Rate Loans then outstanding through the last day of the Interest Period
therefor would cause such Lender to be in violation of such law, regulation or assertion, the
Borrower shall either prepay or Convert all Eurodollar Rate Loans from such Lender within five days
after such notice. Promptly upon becoming aware that the circumstances that caused such Lender to
deliver such notice no longer exist, such Lender shall deliver notice thereof to the Administrative
Agent (but the failure to do so shall impose no liability upon such Lender). Promptly upon receipt
of such notice from such Lender (or upon such Lender’s assigning all of its Commitment, Loans,
participation and other rights and obligations hereunder pursuant to Section 11.07), the
Administrative Agent shall deliver notice thereof to the Borrower and the Lenders and such
suspension shall terminate.

(c) If the Required Lenders shall, at least one Business Day before the date of any requested
Borrowing, notify the Administrative Agent that the Adjusted LIBO Rate for Eurodollar Rate Loans to
be made in connection with such Borrowing will not adequately reflect the cost to such Required
Lenders of making, funding or maintaining their respective Eurodollar Rate Loans for such
Borrowing, or that they are unable to acquire funding in a reasonable manner so as to make
available Eurodollar Rate Loans in the amount and for the Interest Period requested, or if the
Administrative Agent shall determine that adequate and reasonable means do not exist to be able to
determine the Adjusted LIBO Rate, then the right of the Borrower to select Eurodollar Rate Loans
for such Borrowing and any subsequent Borrowing shall be suspended until the Administrative Agent
shall notify the Borrower and the Lenders that the circumstances causing such suspension no longer
exist, and each Loan to be made or Converted in connection with such Borrowing shall be an ABR
Loan.

(d) If any Lender shall have delivered a notice to the Administrative Agent described in
Section 3.04(b), and if and so long as such Lender shall not have withdrawn such notice in
accordance with said Section 3.04(b), the Borrower or the Administrative Agent may demand that such
Lender assign in accordance with Section 11.07, to one or more Eligible Banks designated by the
Borrower or the Administrative Agent (each a “Prospective Lender”), all (but not less than all) of
such Lender’s Commitment, Loans, participation and other rights and obligations hereunder;
provided, that any such demand by the Borrower during the continuance of an Event of Default or
Default shall be ineffective without the consent of the Required Lenders. If, within 30 days
following any such demand by the Administrative Agent or the Borrower, any such Prospective Lender
so designated shall fail to consummate such assignment on terms reasonably satisfactory to such
Lender, or the Borrower and the Administrative Agent shall have failed to designate any such
Prospective Lender, then such demand by the Borrower or the Administrative Agent shall become
ineffective, it being understood for purposes of this provision that such assignment shall be
conclusively deemed to be on terms reasonably satisfactory to such Lender, and such Lender shall be
compelled to consummate such assignment forthwith, if such Prospective Lender (i) shall agree to
such assignment in substantially the form of the Lender Assignment attached hereto as Exhibit F and
(ii) shall tender payment to such Lender in an amount equal to the full outstanding dollar amount
accrued in favor of such Lender hereunder (as computed in accordance with the records of the
Administrative Agent), including, without limitation, all accrued interest and fees and, to the
extent not paid by the Borrower, any payments required pursuant to Section 5.04(b).

(e) Each Notice of Borrowing and Notice of Conversion shall be irrevocable and binding on the
Borrower. In the case of any Borrowing which the related Notice of Borrowing or Notice of
Conversion specifies is to be comprised of Eurodollar Rate Loans, the Borrower shall indemnify each
Lender against any loss, cost or expense incurred by such Lender as a result of any failure to
fulfill, on or before the date specified in such Notice of Borrowing or Notice of Conversion for
such Borrowing, the applicable conditions (if any) set forth in this Article III (other than
failure pursuant to the provisions of Section 3.04(b) or (c) hereof) or in Article VI, including
any such loss (including loss of anticipated profits), cost or expense incurred by reason of the
liquidation or reemployment of deposits or other funds acquired by such Lender to fund the Loan to
be made by such Lender when such Loan, as a result of such failure, is not made on such date.

SECTION 3.05. Repayment of Loans; Interest

(a) Principal. The Borrower shall repay the outstanding principal amount of the Loans on the
Maturity Date (or such earlier date as may be required pursuant to Section 2.03 or 9.02).

(b) Interest. All Loans shall bear interest on the unpaid principal amount thereof from the
date of such Loan until such principal amount shall be paid in full, at the Applicable Rate for
such Loan (except as otherwise provided in this subsection (b)), payable as follows:

(i) ABR Loans. If such Loan is an ABR Loan, interest thereon shall be payable
quarterly in arrears on the last day of each March, June, September and December, on the
date of any Conversion of such ABR Loan and on the date such ABR Loan shall become due and
payable or shall otherwise be paid in full; provided that any amount of principal that is
not paid when due (whether at stated maturity, by acceleration or otherwise) shall bear
interest, from the date on which such amount is due until such amount is paid in full,
payable on demand, at a rate per annum equal at all times to the Default Rate.

(ii) Eurodollar Rate Loans. If such Loan is a Eurodollar Rate Loan, interest thereon
shall be payable on the last day of such Interest Period and, if the Interest Period for
such Loan has a duration of more than three months, on that day of each third month during
such Interest Period that corresponds to the first day of such Interest Period (or, if any
such month does not have a corresponding day, then on the last day of such month); provided
that any amount of principal that is not paid when due (whether at stated maturity, by
acceleration or otherwise) shall bear interest, from the date on which such amount is due
until such amount is paid in full, payable on demand, at a rate per annum equal at all times
to the Default Rate.

ARTICLE IV

LETTERS OF CREDIT

SECTION 4.01. Issuing Banks. Subject to the terms and conditions hereof, the Borrower may
from time to time identify and arrange for one or more Lenders reasonably satisfactory to the
Administrative Agent to act as Issuing Banks hereunder. Any such designation by the Borrower shall
be notified to the Administrative Agent at least three (3) Business Days prior to the first date
upon which the Borrower proposes that such Issuing Bank issue its first Letter of Credit. Nothing
contained herein shall be deemed to require any Lender to agree to act as an Issuing Bank, if it
does not so desire. In the event of any conflict between any Issuing Bank Agreement and this
Agreement, the terms of this Agreement shall control.

SECTION 4.02. Letters of Credit.

(a) Each Letter of Credit shall be issued (or the stated maturity thereof extended or terms
thereof modified or amended) for the account of the Borrower or a Subsidiary of the Borrower (other
than Consumers or any Subsidiary thereof) on not less than three (3) Business Days’ prior written
notice thereof to the Administrative Agent (which shall promptly distribute copies thereof to the
Lenders) and the relevant Issuing Bank and shall be denominated in Dollars or in an Alternative
Currency. Each such notice (a “Request for Issuance”) shall be delivered no later than 12:00 noon
(New York City time) on the third Business Day prior to the proposed date of issuance, extension,
modification or amendment and shall specify (i) the date (which shall be a Business Day) of
issuance of such Letter of Credit (or the date of effectiveness of such extension, modification or
amendment) and the stated expiry date thereof (which shall be no later than the earlier of the date
that is five (5) Business Days (or, in the case of any commercial Letter of Credit, thirty (30)
Business Days) prior to the Commitment Termination Date and the date which is one year after the
requested date of issuance, provided that any Letter of Credit with a one year tenor may provide
for the renewal thereof for additional periods of up to one year which shall in no event extend
beyond the date which is five (5) Business Days (or, in the case of any commercial Letter of
Credit, thirty (30) Business Days) prior to the Commitment Termination Date), (ii) the proposed
stated amount of such Letter of Credit (which shall not be less than $100,000 (or the Dollar
Equivalent thereof in an Alternative Currency) unless otherwise agreed by the applicable Issuing
Bank), (iii) the currency in which such Letter of Credit shall be denominated (which currency shall
be Dollars or an Alternate Currency), and (iv) such other information as shall demonstrate
compliance of such Letter of Credit with the requirements specified therefor in this Agreement and
the relevant Issuing Bank Agreement. Each Request for Issuance shall be irrevocable unless
modified or rescinded by the Borrower in writing not less than two (2) Business Days prior to the
proposed date of issuance (or effectiveness) specified therein. Not later than 12:00 noon (New
York City time) on the proposed date of issuance (or effectiveness) specified in such Request for
Issuance, and upon fulfillment of the applicable conditions precedent and the other requirements
set forth herein and in the relevant Issuing Bank Agreement, such Issuing Bank shall issue (or
extend, amend or modify) such Letter of Credit and provide notice and a copy thereof to the
Administrative Agent, which shall promptly furnish notice thereof to each Lender.

(b) Schedule II contains a schedule of certain letters of credit issued for the account of the
Borrower prior to the Closing Date. Subject to the satisfaction of the applicable conditions
contained in Article VI, from and after the Closing Date such letters of credit shall be deemed to
be Letters of Credit issued pursuant to this Article IV for all purposes hereunder (each such
Letter of Credit, a “Transitional Letter of Credit”). For purposes of clarification, each term or
provision applicable to the issuance of a Letter of Credit (including conditions applicable
thereto) shall be deemed to include the deemed issuance of the Transitional Letters of Credit on
the Closing Date.

(c) Each Lender severally agrees with each Issuing Bank to participate in the Extension of
Credit resulting from the issuance or deemed issuance (or extension, modification or amendment) of
each Letter of Credit issued or deemed issued (or extended, amended or modified) pursuant to this
Section 4.02 in the manner and the amount provided in Section 4.04(b), and the issuance or deemed
issuance of such Letter of Credit shall be deemed to be a confirmation by each Issuing Bank and
each Lender of such participation in such amount.

(d) Notwithstanding anything herein to the contrary, no Issuing Bank shall have any obligation
to, and no Issuing Bank shall, issue, extend, amend or modify any Letter of Credit if on the date
of such issuance, extension, amendment or modification, before or after giving effect thereto, (i)
the Total Outstandings at such time would exceed the Commitments, (ii) the Dollar Equivalent of the
aggregate LC Outstandings with respect to Letters of Credit denominated in euros would exceed the
Euro Sublimit (iii) the Dollar Equivalent of the aggregate LC Outstandings with respect to Letters
of Credit denominated in Indian Rupees would exceed the Indian Rupee Sublimit or (iv) the Dollar
Equivalent of the aggregate LC Outstandings with respect to Letters of Credit denominated in
Canadian Dollars would exceed the Canadian Dollar Sublimit.

SECTION 4.03. Issuing Bank Fees. The Borrower shall pay directly to each Issuing Bank such
fees and expenses, if any, specified to be paid to such Issuing Bank pursuant to each Issuing Bank
Agreement to which it is a party, at the times, and in the manner, specified in such Issuing Bank
Agreement.

SECTION 4.04. Reimbursement to Issuing Banks.

(a) The Borrower hereby agrees to pay to the Administrative Agent for the account of each
Issuing Bank, on demand made by such Issuing Bank to the Borrower and the Administrative Agent, on
and after each date on which such Issuing Bank shall pay any amount under any Letter of Credit
issued by such Issuing Bank, a sum in Dollars equal to the Dollar Equivalent of the amount so paid
(calculated as of the date of such payment by such Issuing Bank) plus interest on such Dollar
Equivalent of such amount from the date so paid by such Issuing Bank until repayment to such
Issuing Bank in full at a fluctuating interest rate per annum equal at all times to the Applicable
Rate for ABR Loans.

(b) If any Issuing Bank shall not have been reimbursed in full by the Borrower for any payment
made by such Issuing Bank under a Letter of Credit issued by such Issuing Bank on the date of such
payment, such Issuing Bank shall give the Administrative Agent and each Lender prompt notice
thereof (an “LC Payment Notice”) no later than 12:00 noon (New York City time) on the Business Day
immediately succeeding the date of such payment by such Issuing Bank. Each Lender severally agrees
to purchase from each Issuing Bank a participation in the reimbursement obligation of the Borrower
to such Issuing Bank under subsection (a) above, by paying to the Administrative Agent for the
account of such Issuing Bank an amount in Dollars equal to such Lender’s Percentage of the Dollar
Equivalent of such unreimbursed amount paid by such Issuing Bank (calculated as of the date of such
payment by such Issuing Bank), plus interest on such Dollar Equivalent of such amount at a rate per
annum equal to the Federal Funds Effective Rate from the date of such payment by such Issuing Bank
to the date of payment to such Issuing Bank by such Lender. Each such payment by a Lender shall be
made not later than 3:00 p.m. (New York City time) on the later to occur of (i) the Business Day
immediately following the date of such payment by such Issuing Bank and (ii) the Business Day on
which such Lender shall have received an LC Payment Notice from such Issuing Bank. Each Lender’s
obligation to make each such payment to the Administrative Agent for the account of such Issuing
Bank shall be several and shall not be affected by the occurrence or continuance of any Default or
Event of Default or the failure of any other Lender to make any payment under this Section 4.04.
Each Lender further agrees that each such payment shall be made without any offset, abatement,
withholding or reduction whatsoever.

(c) The failure of any Lender to make any payment to the Administrative Agent for the account
of an Issuing Bank in accordance with subsection (b) above, shall not relieve any other Lender of
its obligation to make payment, but no Lender shall be responsible for the failure of any other
Lender. If any Lender shall fail to make any payment to the Administrative Agent for the account
of an Issuing Bank in accordance with subsection (b) above, within five (5) Business Days after the
LC Payment Notice relating thereto, then, for so long as such failure shall continue, such Issuing
Bank shall be deemed, for purposes of Section 5.05 and Article IX hereof and the Cash Collateral
Agreement, to be a Lender hereunder owed a Loan in an outstanding principal amount equal to the
amount due and payable by such Lender to the Administrative Agent for the account of such Issuing
Bank pursuant to subsection (b) above.

(d) Each participation purchased by a Lender under subsection (b) above, shall constitute an
ABR Loan in the amount in Dollars paid by such Lender to the Administrative Agent for the account
of the applicable Issuing Bank and shall be deemed made by such Lender to the Borrower on the date
of the related payment by the relevant Issuing Bank under the applicable Letter of Credit issued by
such Issuing Bank (irrespective of the Borrower’s noncompliance, if any, with the conditions
precedent for Loans hereunder); and all such payments by the Lenders in respect of any one such
payment by such Issuing Bank shall constitute a single Borrowing hereunder.

SECTION 4.05. Obligations Absolute. The payment obligations of each Lender under Section
4.04(b) and of the Borrower under this Agreement in respect of any payment under any Letter of
Credit and any Loan made under Section 4.04(d) shall be unconditional and irrevocable, and shall be
paid strictly in accordance with the terms of this Agreement under all circumstances, including the
following circumstances:

(i) any lack of validity or enforceability of any Loan Document or any other agreement
or instrument relating thereto or to such Letter of Credit;

(ii) any amendment or waiver of, or any consent to departure from, all or any of the
Loan Documents;

(iii) the existence of any claim, set-off, defense or other right which the Borrower
may have at any time against any beneficiary, or any transferee, of such Letter of Credit
(or any Persons for whom any such beneficiary or any such transferee may be acting), any
Issuing Bank, or any other Person, whether in connection with this Agreement, the
transactions contemplated herein or by such Letter of Credit, or any unrelated transaction;

(iv) any statement or any other document presented under such Letter of Credit proving
to be forged, fraudulent, invalid or insufficient in any respect or any statement therein
being untrue or inaccurate in any respect;

(v) payment in good faith by any Issuing Bank under a Letter of Credit issued by such
Issuing Bank against presentation of a draft or certificate which does not comply with the
terms of such Letter of Credit; or

(vi) any other circumstance or happening whatsoever, whether or not similar to any of
the foregoing.

SECTION 4.06. Indemnification; Liability of Issuing Banks and the Lenders.

(a) In addition to amounts payable as elsewhere provided in this Agreement, the Borrower
hereby agrees to pay and to protect, indemnify, and save harmless each Indemnified Person from and
against any and all liabilities and costs that any such Indemnified Person may incur or be subject
to as a consequence, direct or indirect, of (i) the issuance, execution and delivery or transfer of
or payment or failure to pay under any Letter of Credit or (ii) the failure of any Issuing Bank to
honor a demand for payment under any Letter of Credit as a result of any act or omission, whether
rightful or wrongful, of any present or future de jure or de facto government or governmental
authority, in each case other than to the extent solely as a result of the (x) gross negligence or
willful misconduct of such Indemnified Person as determined by a court of competent jurisdiction by
final and nonappealable judgment or (y) any Issuing Bank’s failure to pay under any Letter of
Credit after the presentation to it of a request strictly complying with the terms and conditions
of such Letter of Credit.

(b) The Borrower assumes all risks of the acts and omissions of any beneficiary or transferee
of any Letter of Credit. Neither the Issuing Bank that has issued such Letter of Credit, nor any
other Indemnified Person, shall be liable or responsible for (i) the use that may be made of such
Letter of Credit or any acts or omissions of any beneficiary or transferee thereof in connection
therewith; (ii) the validity, sufficiency or genuineness of documents, or of any endorsement
thereon, even if such documents should prove to be in any or all respects invalid, insufficient,
fraudulent or forged; (iii) payment by such Issuing Bank against presentation of documents that do
not comply with the terms of such Letter of Credit, including failure of any documents to bear any
reference or adequate reference to such Letter of Credit; or (iv) any other circumstances
whatsoever in making or failing to make payment under such Letter of Credit, except that the
Borrower shall have the right to bring suit against such Issuing Bank, and such Issuing Bank shall
be liable to the Borrower and any Lender, to the extent of any direct, as opposed to consequential,
damages suffered by the Borrower or such Lender which the Borrower or such Lender proves were
caused by such Issuing Bank’s willful misconduct or gross negligence as determined by a court of
competent jurisdiction by final and nonappealable judgment, including such Issuing Bank’s willful
failure to make timely payment under such Letter of Credit following the presentation to it by the
beneficiary thereof of a draft and accompanying certificate(s) which strictly comply with the terms
and conditions of such Letter of Credit. In furtherance and not in limitation of the foregoing,
any Issuing Bank may accept sight drafts and accompanying certificates presented under any Letter
of Credit issued by such Issuing Bank that appear on their face to be in order, without
responsibility for further investigation, regardless of any notice or information to the contrary.
Notwithstanding the foregoing, no Lender shall be obligated to indemnify the Borrower for damages
caused by any Issuing Bank’s willful misconduct or gross negligence, and the obligation of the
Borrower to reimburse the Lenders hereunder shall be absolute and unconditional, notwithstanding
the gross negligence or willful misconduct of any Issuing Bank.

(c) The Borrower’s other obligations under this Section 4.06 shall survive the repayment of
all amounts owing to the Lenders, the Issuing Banks and the Agents under the Loan Documents and the
termination of the Commitments. If and to the extent that the obligations of the Borrower under
this Section 4.06 are unenforceable for any reason, the Borrower agrees to make the maximum
contribution to the payment and satisfaction thereof which is permissible under applicable law.

SECTION 4.07. Currency Equivalents. The Dollar Equivalent of any amount denominated in any
Alternative Currency shall be determined by the Issuing Bank in accordance with prevailing exchange
rates, as set forth in the applicable Issuing Bank Agreement, and notice of such amount shall be
provided to the Administrative Agent, in each case on the applicable date. The Dollar Equivalent of
the stated amount of each Letter of Credit outstanding made in an Alternative Currency and of the
amount of each participation purchased by a Lender under Section 4.04(b) shall be recalculated
hereunder on (i) each date that it shall be necessary to determine the unused portion of each
Lender’s Commitment, or the outstanding amount of any or all Loans, LC Outstandings or any
Extension of Credit, or (ii) on any such other date which the Administrative Agent deems such
recalculation necessary or advisable or is otherwise directed to make such recalculation by the
Required Lenders, but in any event at least monthly. The Administrative Agent agrees to provide
notice to the Lenders of the relevant Dollar Equivalent determined pursuant to each such
determination and each such recalculation as soon as practicable following such determination or
recalculation, as the case may be.

SECTION 4.08. Judgment Currency. If for the purposes of obtaining judgment in any court it is
necessary to convert a sum due hereunder or under the Promissory Notes in any currency (the
“Original Currency”) into another currency (the “Other Currency”) the parties hereto agree, to the
fullest extent that they may effectively do so, that the rate of exchange used shall be that at
which in accordance with normal banking procedures the Administrative Agent could purchase the
Original Currency with the Other Currency at the Administrative Agent’s main office in New York,
New York on the Business Day immediately preceding that on which final judgment is given. The
obligation of the Borrower in respect of any sum due in the Original Currency from it to any
Lender, any Issuing Bank, the Collateral Agent or Administrative Agent hereunder or under any other
Loan Document shall, notwithstanding any judgment in any Other Currency, be discharged only to the
extent that on the Business Day following receipt by such Lender, Issuing Bank, Collateral Agent or
the Administrative Agent (as the case may be) of any sum adjudged to be so due in such Other
Currency such Lender, Issuing Bank, Collateral Agent or Administrative Agent (as the case may be)
may in accordance with normal banking procedures purchase the Original Currency with such Other
Currency; if the amount of the Original Currency so purchased is less than the sum originally due
to such Lender, Issuing Bank, Collateral Agent or Administrative Agent (as the case may be) in the
Original Currency, the Borrower agrees, as a separate obligation and notwithstanding any such
judgment, to indemnify such Lender, Issuing Lender, Collateral Agent or Administrative Agent (as
the case may be) against such loss, and if the amount of the Original Currency so purchased exceeds
the sum originally due in the Original Currency to any Lender, Issuing Lender, Collateral Agent or
Administrative Agent (as the case may be), such Lender, Issuing Lender, Collateral Agent or
Administrative Agent (as the case may be) agrees to remit to the Borrower such excess.

SECTION 4.09. Cash Collateral Agreement. The Borrower agrees that it will maintain pursuant
to the Cash Collateral Agreement a cash collateral account, in the name of the Borrower but under
the sole dominion and control of the Collateral Agent, for the benefit of itself, the
Administrative Agent, the LC Issuers and the Lenders. The Borrower hereby pledges, assigns and
grants to the Collateral Agent, for the benefit of itself, the Administrative Agent, the LC Issuers
and the Lenders, a security interest in all of its right, title and interest in and to all funds
which may from time to time be on deposit in such account to secure the prompt and complete payment
and performance of all reimbursement obligations of the Borrower now or hereafter existing with
respect to LC Obligations.

SECTION 4.10. Court Order. If at any time any Issuing Bank shall have been served with or
otherwise subjected to a court order, injunction, or other process or decree issued or granted at
the instance of the Borrower restraining or seeking to restrain such Issuing Bank from paying any
amount under any Letter of Credit issued by it (other than pursuant to any action or proceeding
based on Section 5-109 of the Uniform Commercial Code) and either (i) there has been a drawing
under such Letter of Credit which such Issuing Bank would otherwise be obligated to pay or (ii) the
stated expiration date or any reduction of the stated amount of such Letter of Credit has occurred
but the right of the beneficiary to draw thereunder has been extended in connection with the
pendency of the related court action or proceeding, the Borrower shall provide cash collateral
pursuant to the Cash Collateral Agreement in an amount equal to one hundred five percent (105%) of
the Dollar Equivalent of the LC Outstandings at such time in respect of such Letter of Credit.

ARTICLE V

PAYMENTS, COMPUTATIONS AND YIELD PROTECTION

SECTION 5.01. Payments and Computations.

(a) The Borrower shall make each payment hereunder and under the other Loan Documents not
later than 2:00 p.m. (New York City time) on the day when due in Dollars to the Administrative
Agent at its offices at 2 Penns Way, Suite 200, New Castle, DE 19270, in same day funds, except
payments to be made directly to any Issuing Bank as expressly provided herein; any payment received
after 3:00 p.m. (New York City time) shall be deemed to have been received at the start of business
on the next succeeding Business Day, unless the Administrative Agent shall have received from, or
on behalf of, the Borrower a Federal Reserve reference number with respect to such payment before
4:00 p.m. (New York City time). The Administrative Agent will promptly thereafter cause to be
distributed like funds relating to the payment of principal, interest, fees or other amounts
payable to the Lenders, to the respective Lenders to which the same are payable, for the account of
their respective Applicable Lending Offices, in each case to be applied in accordance with the
terms of this Agreement. If and to the extent that any distribution of any payment from the
Borrower required to be made to any Lender pursuant to the preceding sentence shall not be made in
full by the Administrative Agent on the date such payment was received by the Administrative Agent,
the Administrative Agent shall pay to such Lender, upon demand, interest on the unpaid amount of
such distribution, at a rate per annum equal to the Federal Funds Effective Rate, from the date of
such payment by the Borrower to the Administrative Agent to the date of payment in full by the
Administrative Agent to such Lender of such unpaid amount. Upon the Administrative Agent’s
acceptance of a Lender Assignment and recording of the information contained therein in the
Register pursuant to Section 11.07, from and after the effective date specified in such Lender
Assignment, the Administrative Agent shall make all payments hereunder and under any Promissory
Notes in respect of the interest assigned thereby to the Lender assignee thereunder, and the
parties to such Lender Assignment shall make all appropriate adjustments in such payments for
periods prior to such effective date directly between themselves.

(b) The Borrower hereby authorizes the Administrative Agent, each Lender and each Issuing
Bank, if and to the extent payment owed to the Administrative Agent, such Lender or such Issuing
Bank, as the case may be, is not made when due hereunder (or, in the case of a Lender, under any
Promissory Note held by such Lender), to charge from time to time against any or all of the
Borrower’s accounts with the Administrative Agent, such Lender or such Issuing Bank, as the case
may be, any amount so due.

(c) All computations of interest based on the Alternate Base Rate (when the Alternate Base
Rate is based on the Prime Rate) shall be made by the Administrative Agent on the basis of a year
of 365 or 366 days, as the case may be. All other computations of interest and fees hereunder
(including computations of interest based on the Adjusted LIBO Rate, the CD Rate and the Federal
Funds Effective Rate) shall be made by the Administrative Agent on the basis of a year of 360 days.
In each such case, such computation shall be made for the actual number of days (including the
first day but excluding the last day) occurring in the period for which such interest or fees are
payable. Each such determination by the Administrative Agent or a Lender shall be conclusive and
binding for all purposes, absent manifest error.

(d) Whenever any payment hereunder or under any other Loan Document 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
and fees hereunder; provided, however, that if such extension would cause payment of interest on or
principal of Eurodollar Rate Loans to be made in the next following calendar month, such payment
shall be made on the next preceding Business Day and such reduction of time shall in such case be
included in the computation of payment of interest hereunder.

(e) Unless the Administrative Agent shall have received notice from the Borrower prior to the
date on which any payment is due to the Lenders 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 Lender on such due date an amount equal to the
amount then due such Lender. If and to the extent the Borrower shall not have so made such payment
in full to the Administrative Agent, such Lender shall repay to the Administrative Agent forthwith
on demand such amount distributed to such Lender, together with interest thereon, for each day from
the date such amount is distributed to such Lender until the date such Lender repays such amount to
the Administrative Agent, at the Federal Funds Effective Rate.

(f) Any amount payable by the Borrower hereunder or under any of the Promissory Notes that is
not paid when due (whether at stated maturity, by acceleration or otherwise) shall (to the fullest
extent permitted by law) bear interest, from the date when due until paid in full, at a rate per
annum equal at all times to the Default Rate, payable on demand.

(g) If at any time insufficient funds are received by and available to the Administrative
Agent to pay fully all amounts of principal, interest and fees then due hereunder, such funds shall
be applied, subject to Section 5.07, (i) first, toward payment of interest and fees then due
hereunder, ratably among the parties entitled thereto in accordance with the amounts of interest
and fees then due to such parties, and (ii) second, toward payment of principal then due hereunder,
ratably among the parties entitled thereto.

SECTION 5.02. Interest Rate Determination. The Administrative Agent shall give prompt notice
to the Borrower and the Lenders of the applicable interest rate determined by the Administrative
Agent for purposes of Section 3.05(b)(i) or (ii).

SECTION 5.03. Prepayments. The Borrower shall have no right to prepay any principal amount of
any Loans other than as follows:

(a) The Borrower may (and shall provide notice thereof to the Administrative Agent not later
than 10:00 a.m. (New York City time) on the date of prepayment, and the Administrative Agent shall
promptly distribute copies thereof to the Lenders), and if such notice is given, the Borrower
shall, prepay the outstanding principal amounts of the Loans made as part of the same Borrowing, in
whole or ratably in part; provided, however, that each partial prepayment shall be in an aggregate
principal amount of not less than $5,000,000 or an integral multiple of $1,000,000 in excess
thereof (or such lesser amount as shall be equal to the total amount of Loans outstanding to the
Borrower).

(b) On any date on which (i) any termination or optional or mandatory reduction of the
Commitments shall occur pursuant to Section 2.03(a) or (b) or (ii) the Total Outstandings shall
exceed the aggregate amount of the Commitments, the Borrower shall first, pay or prepay the
principal outstanding on the Loans and/or all LC Outstandings that represent amounts that have been
drawn under Letters of Credit but have neither been reimbursed by the Borrower nor converted into
ABR Loans, second, if all of the Loans and all of such unreimbursed amounts constituting LC
Outstanding shall have been paid in full, provide cash collateral pursuant to the Cash Collateral
Agreement, to secure remaining LC Outstandings, and third, cause an amount of Letters of Credit to
be cancelled (if necessary after taking into account the payments and provision of cash collateral
in the immediately preceding clauses), in each case, in an aggregate amount equal to the excess, as
applicable, of (A) the Total Outstandings over (B) the aggregate amount of the sum of the
Commitments (following such termination or reduction, if any) and any cash collateral on deposit in
the Cash Collateral Account. Any payments and prepayments required by clause “first” of this
subsection (b) shall be applied to outstanding ABR Loans up to the full amount thereof before they
are applied to outstanding Eurodollar Rate Loans.

(c) On any date on which (i) the aggregate Dollar Equivalent of all LC Outstandings
denominated in euros shall exceed the Euro Sublimit, (ii) all LC Outstandings denominated in Indian
Rupees shall exceed the Indian Rupee Sublimit, or (iii) the aggregate Dollar Equivalent of all LC
Outstandings denominated in Canadian Dollars shall exceed the Canadian Dollar Sublimit, the
Borrower shall provide cash collateral pursuant to the Cash Collateral Agreement, to secure the LC
Outstandings in an aggregate amount equal to the excess, as applicable, of (A)(1) the aggregate
Dollar Equivalent of all LC Outstandings denominated in euro, over (2) the sum of the Euro Sublimit
and, without duplication, such cash collateral, (B)(1) the aggregate Dollar Equivalent of all LC
Outstandings denominated in Indian Rupees, over (2) the sum of the Indian Rupee Sublimit and,
without duplication, such cash collateral or (C)(1) the aggregate Dollar Equivalent of all LC
Outstandings denominated in Canadian Dollars, over (2) the sum of the Canadian Dollar Sublimit and,
without duplication, such cash collateral.

(d) Any prepayment pursuant to this Section 5.03 shall be accompanied by (i) accrued interest
to the date of such prepayment on the principal amount repaid and (ii) in the case of prepayments
of Eurodollar Rate Loans, any amount payable to the Lenders pursuant to Section 5.04(b). In the
event that the Borrower requests the release of any cash collateral pursuant to the terms of the
Cash Collateral Agreement and on the date of such request or at any time prior to the time of such
release, there has become, or there becomes, due and payable any prepayment of any Loans under this
Agreement, the Borrower hereby directs the Administrative Agent to apply the proceeds of such
release of cash collateral to such prepayment of such Loans and agrees that any such request is a
confirmation of such direction.

SECTION 5.04. Yield Protection.

(a) Increased Costs. If, due to either (i) the introduction of or any change in or in the
interpretation of any law or regulation after the Closing Date, or (ii) the compliance with any
guideline or request from any central bank or other governmental authority (whether or not having
the force of law) issued or made after the Closing Date, there shall be reasonably incurred any
increase in (A) the cost to any Lender of agreeing to make or making, funding or maintaining
Eurodollar Rate Loans, or of participating in the issuance, maintenance or funding of any Letter of
Credit, or (B) the cost to any Issuing Bank of issuing or maintaining any Letter of Credit, then
the Borrower shall from time to time, upon demand by such Lender or Issuing Bank, as the case may
be (with a copy of such demand to the Administrative Agent), pay to the Administrative Agent for
the account of such Lender or Issuing Bank, as the case may be, additional amounts sufficient to
compensate such Lender or Issuing Bank, as the case may be, for such increased cost. A certificate
as to the amount of such increased cost and giving a reasonable explanation thereof, submitted to
the Borrower and the Administrative Agent by such Lender or such Issuing Bank, as the case may be,
shall constitute such demand and shall be conclusive and binding for all purposes, absent manifest
error.

(b) Breakage. If (i) due to any prepayment pursuant to Section 2.03, an acceleration of
maturity of the Loans pursuant to Section 9.02, or any other reason, any Lender receives payments
of principal of any Eurodollar Rate Loan other than on the last day of the Interest Period relating
to such Loan, (ii) the Borrower shall Convert any Eurodollar Rate Loans on any day other than the
last day of the Interest Period therefor, (iii) the Borrower shall fail to prepay a Eurodollar Rate
Loan on the date specified in a notice of prepayment or (iv) a Eurodollar Rate Loan is not made or
continued, or an ABR Loan is not Converted to a Eurodollar Rate Loan, on the date specified by the
Borrower in the applicable Notice of Borrowing or Notice of Conversion, the Borrower shall,
promptly after demand by such Lender (with a copy of such demand to the Administrative Agent), pay
to the Administrative Agent for the account of such Lender any amounts required to compensate such
Lender for additional losses, costs, or expenses (including anticipated lost profits) that such
Lender may reasonably incur as a result of such occurrence, including any loss, cost or expense
incurred by reason of the liquidation or reemployment of deposits or other funds acquired by such
Lender to fund or maintain such Loan. For purposes of this subsection (b), a certificate setting
forth the amount of such additional losses, costs, or expenses and giving a reasonable explanation
thereof, submitted to the Borrower and the Administrative Agent by such Lender, shall constitute
such demand and shall be conclusive and binding for all purposes, absent manifest error.

(c) Capital. If any Lender or Issuing Bank determines that (i) compliance 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) affects or would affect the amount of capital required or
expected to be maintained by such Lender or Issuing Bank, whether directly, or indirectly as a
result of commitments of any Person controlling such Lender or Issuing Bank (but without
duplication), and (ii) the amount of such capital is increased by or based upon (A) the existence
of such Lender’s or such Issuing Bank’s commitment to lend or issue or participate in any Letter of
Credit hereunder, (B) the participation in or issuance or maintenance of any Letter of Credit or
Loan or (C) other similar such commitments, then, upon demand by such Lender or Issuing Bank, the
Borrower agrees immediately to pay to the Administrative Agent for the account of such Lender or
Issuing Bank from time to time as specified by such Lender or Issuing Bank additional amounts
sufficient to compensate such Lender or Issuing Bank in the light of such circumstances, to the
extent that such Lender or Issuing Bank reasonably determines such increase in capital to be
allocable to the transactions contemplated hereby. A certificate as to such amounts and giving a
reasonable explanation thereof (to the extent permitted by law), submitted to the Borrower and the
Administrative Agent by such Lender or Issuing Bank, shall be conclusive and binding for all
purposes, absent manifest error.

(d) Notices. Each Lender and Issuing Bank hereby agrees to use its best efforts to notify the
Borrower of the occurrence of any event referred to in subsection (a), (b) or (c) of this Section
5.04 promptly after becoming aware of the occurrence thereof. The failure of any Lender or any
Issuing Bank to provide such notice or to make demand for payment under said subsection shall not
constitute a waiver of such Lender’s or such Issuing Bank’s (as the case may be) rights hereunder;
provided that, notwithstanding any provision to the contrary contained in this Section 5.04, the
Borrower shall not be required to reimburse any Lender or any Issuing Bank for any amounts or costs
incurred under subsection (a), (b) or (c) of this Section 5.04 more than 90 days prior to the date
that such Lender or such Issuing Bank’s (as the case may be) notifies the Borrower in writing
thereof, in each case unless, and to the extent that, any such amounts or costs so incurred shall
relate to the retroactive application of any event notified to the Borrower which entitles such
Lender or such Issuing Bank (as the case may be) to such compensation. If any Lender or any
Issuing Bank shall subsequently determine that any amount demanded and collected under this Section
5.04 was done so in error, such Lender or such Issuing Bank (as the case may be) will promptly
return such amount to the Borrower.

(e) Survival of Obligations. Subject to subsection (d) above, the Borrower’s obligations
under this Section 5.04 shall survive the repayment of all other amounts owing to the Lenders, the
Agents and the Issuing Banks under the Loan Documents and the termination of the Commitments. If
and to the extent that the obligations of the Borrower under this Section 5.04 are unenforceable
for any reason, the Borrower agrees to make the maximum contribution to the payment and
satisfaction thereof which is permissible under applicable law.

SECTION 5.05. Sharing of Payments, Etc. If any Lender shall obtain any payment (whether
voluntary, involuntary, through the exercise of any right of set-off, or otherwise) on account of
the Loans owing to it (other than pursuant to Section 5.04 or Section 5.06) in excess of its
ratable share of payments obtained by all the Lenders on account of the Loans of such Lenders, such
Lender shall forthwith purchase from the other Lenders such participation in the Loans owing to
them as shall be necessary to cause such purchasing Lender to share the excess payment ratably with
each of them; provided, however, that if all or any portion of such excess payment is thereafter
recovered from such purchasing Lender, such purchase from each Lender shall be rescinded and such
Lender shall repay to the purchasing Lender the purchase price to the extent of such recovery
together with an amount equal to such Lender’s ratable share (according to the proportion of
(i) the amount of such Lender’s required repayment to (ii) the total amount so recovered from the
purchasing Lender) of any interest or other amount paid or payable by the purchasing Lender in
respect of the total amount so recovered. The Borrower agrees that any Lender so purchasing a
participation from another Lender pursuant to this Section 5.05 may, to the fullest extent
permitted by law, exercise all its rights of payment (including the right of set-off) with respect
to such participation as fully as if such Lender were the direct creditor of the Borrower in the
amount of such participation. Notwithstanding the foregoing, if any Lender shall obtain any such
excess payment involuntarily, such Lender may, in lieu of purchasing participations from the other
Lenders in accordance with this Section 5.05, on the date of receipt of such excess payment, return
such excess payment to the Administrative Agent for distribution in accordance with Section
5.01(a).

SECTION 5.06. Taxes.

(a) All payments by the Borrower hereunder and under the other Loan Documents shall be made in
accordance with Section 5.01, free and clear of and without deduction for all present or future
taxes, levies, imposts, deductions, charges or withholdings, and all liabilities with respect
thereto, excluding, in the case of each Lender, each Issuing Bank and each Agent, taxes imposed on
its overall net income, and franchise taxes imposed on it by the jurisdiction under the laws of
which such Lender, Issuing Bank or Agent (as the case may be) is organized or any political
subdivision thereof and, in the case of each Lender, taxes imposed on its overall net income, and
franchise taxes imposed on it by the jurisdiction of such Lender’s Applicable Lending Office or any
political subdivision thereof (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
other Loan Document to any Lender, Issuing Bank or 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 5.06) such Lender, Issuing Bank or 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.

(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 other Loan Document or from the execution, delivery or registration of, or
otherwise with respect to, this Agreement or any other Loan Document (hereinafter referred to as
“Other Taxes”).

(c) The Borrower agrees to indemnify each Lender, Issuing Bank and Agent for the full amount
of Taxes and Other Taxes (including any Taxes and any Other Taxes imposed by any jurisdiction on
amounts payable under this Section 5.06) paid by such Lender, Issuing Bank or Agent (as the case
may be) and any liability (including penalties, interest and expenses) arising therefrom or with
respect thereto, whether or not such Taxes or Other Taxes were correctly or legally asserted. This
indemnification shall be made within thirty (30) days from the date such Lender, Issuing Bank or
Agent (as the case may be) makes written demand therefor; provided, that such Lender, Issuing Bank
or Agent (as the case may be) shall not be entitled to demand payment under this Section 5.06 for
an amount if such demand is not made within one year following the date upon which such Lender,
Issuing Bank or Agent (as the case may be) shall have been required to pay such amount.

(d) Within thirty (30) days after the date of any payment of Taxes, the Borrower will furnish
to the Administrative Agent, at its address referred to in Section 11.02, the original or a
certified copy of a receipt evidencing payment thereof.

(e) Each Bank represents and warrants that either (i) it is organized under the laws of a
jurisdiction within the United States or (ii) it has delivered to the Borrower or the
Administrative Agent duly completed copies of such form or forms prescribed by the United States
Internal Revenue Service indicating that such Bank is entitled to receive payments without
deduction or withholding of any United States federal income taxes, as permitted by the Internal
Revenue Code of 1986, as amended. Each other Lender agrees that, on or prior to the date upon
which it shall become a party hereto, and upon the reasonable request from time to time of the
Borrower or the Administrative Agent, such Lender will deliver to the Borrower and the
Administrative Agent (to the extent that it is not prohibited by law from doing so) either (A) a
statement that it is organized under the laws of a jurisdiction within the United States or
(B) duly completed copies of such form or forms as may from time to time be prescribed by the
United States Internal Revenue Service, indicating that such Lender is entitled to receive payments
without deduction or withholding of any United States federal income taxes, as permitted by the
Internal Revenue Code of 1986, as amended. Each Bank that has delivered, and each other Lender
that hereafter delivers, to the Borrower and the Administrative Agent the form or forms referred to
in the two preceding sentences further undertakes to deliver to the Borrower and the Administrative
Agent, to the extent that it is not prohibited by law from doing so, further copies of such form or
forms, or successor applicable form or forms, as the case may be, as and when any previous form
filed by it hereunder shall expire or shall become incomplete or inaccurate in any respect. Each
Lender represents and warrants that each such form supplied by it to the Administrative Agent and
the Borrower pursuant to this subsection (e), and not superseded by another form supplied by it, is
or will be, as the case may be, complete and accurate.

SECTION 5.07. Apportionment of Payments.

(a) Subject to the provisions of Section 2.03, Section 5.03(b) and Section 5.07(b), all
payments of principal and interest in respect of outstanding Loans, all payments in respect of
unpaid reimbursement obligations under Section 4.04(a), all payments of fees and all other payments
in respect of any other Obligations hereunder, shall be allocated among such of the Lenders and the
Issuing Banks as are entitled thereto, ratably or otherwise as expressly provided herein. Except
as provided in Section 5.07(b) with respect to payments and proceeds of Collateral received after
the occurrence of an Event of Default, all such payments and any other amounts received by the
Administrative Agent from or for the benefit of the Borrower shall be applied:

(i) first, to pay principal of and interest on any portion of the Loans which the
Administrative Agent may have advanced on behalf of any Lender other than Citibank for which
the Administrative Agent has not then been reimbursed by such Lender or the Borrower;

(ii) second, to pay interest on and then the principal of the Loans then due and
payable (in the order described hereinbelow);

(iii) third to pay principal of and interest on all unpaid reimbursement obligations
under Section 4.04(a);

(iv) fourth, to the Cash Collateral Account, to secure outstanding Letters of Credit to
the extent required pursuant to this Agreement;

(v) fifth, to pay all other Obligations under any Loan Document then due and payable,
ratably; and

(vi) sixth, as the Borrower so designates.

All such principal and interest payments in respect of the Loans shall be applied first to repay
outstanding ABR Loans and then to repay outstanding Eurodollar Rate Loans with those Eurodollar
Rate Loans which have earlier expiring Interest Periods being repaid prior to those which have
later expiring Interest Periods.

(b) During the continuance of an Event of Default and after declaration thereof by written
notice from the Administrative Agent to the Borrower, the Administrative Agent shall apply all
payments in respect of Loans, unpaid reimbursement obligations under Section 4.04(a) or any other
Obligations, and the Collateral Agent shall deliver all proceeds of Collateral to the
Administrative Agent for application, in the following order:

(i) first, to pay principal of and interest on any portion of the Loans which the
Administrative Agent may have advanced on behalf of any Lender other than Citibank for which
the Administrative Agent has not then been reimbursed by such Lender or the Borrower;

(ii) second, to pay any fees, expense reimbursements or indemnities then due to the
Agents under any of the Loan Documents;

(iii) third, to the ratable payment of any fees, expense reimbursements or indemnities
then due to the Lenders and the Issuing Banks under any of the Loan Documents;

(iv) fourth, to the ratable payment of interest due in respect of the Loans, in
accordance with the Lenders’ respective Percentages;

(v) fifth, to the ratable payment or prepayment of principal outstanding on all Loans,
in accordance with the Lenders’ respective Percentages;

(vi) sixth, to pay principal of and interest on all unpaid reimbursement obligations
under Section 4.04(a);

(vii) seventh, to the Cash Collateral Account to secure LC Obligations in respect of
outstanding Letters of Credit, in an amount equal to the Cash Collateral Required Amount;
and

(viii) eighth, to the ratable payment of all other Obligations then outstanding under
the Loan Documents.

The order of priority set forth in this Section 5.07(b) and the related provisions of this
Agreement are set forth solely to determine the rights and priorities of the Agents and the Lenders
as among themselves.

SECTION 5.08. Proceeds of Collateral. During the continuance of an Event of Default and after
declaration thereof by written notice from the Administrative Agent to the Borrower, the Borrower
shall cause all proceeds of Collateral to be deposited pursuant to arrangements for the collection
of such amounts established by the Borrower and the Administrative Agent (or the Collateral Agent,
as applicable) for application pursuant to Section 5.07. All collections of proceeds of Collateral
which are received directly by the Borrower shall be deemed to have been received by the Borrower
as the Collateral Agent’s trustee and, during the continuance of an Event of Default and after
declaration thereof by written notice from the Administrative Agent to the Borrower, upon the
Borrower’s receipt thereof, the Borrower shall immediately transfer all such amounts to the
Administrative Agent for application pursuant to Section 5.07. All other proceeds of Collateral
received by the Collateral Agent and/or the Administrative Agent, whether through direct payment or
otherwise, will be deemed received by such Agent, will be the sole property of such Agent, and will
be held by such Agent, for the benefit of the Lenders for application pursuant to Section 5.07.

constituting Collateral at the time of such release to be pledged to the Collateral Agent as
security for the Obligations pursuant to documentation reasonably satisfactory to the
Administrative Agent in form and substance.

party to this Agreement); or

(d) The Borrower or any of its Subsidiaries shall fail to perform or observe any other term or

grace period, if any, specified in any agreement or instrument relating to such Debt; or any other
default under any agreement or instrument relating to any such Debt (including any “amortization
event” or event of like import in connection with any Off-Balance Sheet Liabilities), or any other
event, shall occur and shall continue after the applicable grace period, if any, specified in such
agreement or instrument, if the effect of such default or event is (i) to accelerate, or to permit
the acceleration of, the maturity of such Debt; or any such Debt shall be declared to be due and
payable, or required to be prepaid (other than by a regularly scheduled required prepayment) prior
to the stated maturity thereof; unless in each such case the obligee under or holder of such Debt

or (ii) with respect to any such event occurring in connection with any Off-Balance Sheet
Liabilities aggregating $25,000,000 or more, to terminate the reinvestment of collections or
proceeds of receivables and related security under any agreements or instruments related thereto
(other than a termination resulting solely from the request of the Borrower or its Subsidiaries);
or

(f) (i) The Borrower, any Restricted Subsidiary or Consumers shall generally not pay its
debts as such debts become due, or shall admit in writing its inability to pay its debts generally,

similar official for the Borrower, such Restricted Subsidiary or Consumers or any of its property)
shall occur; or (iii) the Borrower, any Restricted Subsidiary or Consumers shall take any corporate
or other action to authorize any of the actions set forth above in this subsection (f); or

(g) Any judgment or order for the payment of money in excess of $25,000,000 shall be rendered
against the Borrower or any Restricted Subsidiary or any of their respective properties and either
(i) enforcement proceedings shall have been commenced by any creditor upon such judgment or order
or (ii) there shall be any period of 30 consecutive days during which a stay of enforcement of such
judgment or order, by reason of a pending appeal or otherwise, shall not be in effect; or

(h) Any material provision of any Loan Document, after execution hereof or delivery thereof
under Article VI, shall for any reason other than the express terms hereof or thereof cease to be
valid and binding on any party thereto; or the Borrower shall so assert in writing; or

(i) At any time, for any reason (except to the extent permitted by the terms of the Loan
Documents or due to any failure by the Collateral Agent to take any action on its part to be
performed under applicable law in order to maintain the perfection or priority of any such Liens),
(i) the Liens intended to be created under any of the Loan Documents with respect to Collateral
having a Fair Market Value of $10,000,000 or more become, or the Borrower or any of its
Subsidiaries seeks to render such Liens, invalid or unperfected, or (ii) Liens in favor of the
Collateral Agent for the benefit of the Lenders contemplated by the Loan Documents with respect to
Collateral having a Fair Market Value of $10,000,000 or more shall, at any time, for any reason, be
invalidated or otherwise cease to be in full force and effect, or such Liens shall not have the
priority contemplated by this Agreement or the Loan Documents.

SECTION 9.02. Remedies. If any Event of Default has occurred and is continuing, then the
Administrative Agent or the Collateral Agent, as applicable, shall at the request, or may with the
consent, of the Required Lenders, upon notice to the Borrower (i) declare the Commitments and the
obligation of each Lender to make or Convert Loans (other than Loans under Section 4.04) and of any
Issuing Bank to issue Letters of Credit to be terminated, whereupon the same shall forthwith
terminate, (ii) declare the principal amount outstanding hereunder, all interest thereon and all
other amounts payable under this Agreement and the other Loan Documents to be forthwith due and
payable, whereupon the principal amount outstanding hereunder, all such interest and all such
amounts shall become and be forthwith due and payable, without presentment, demand, protest or
further notice of any kind, all of which are hereby expressly waived by the Borrower, (iii) make
demand on the Borrower to pay, and the Borrower will be obligated to, upon such demand without any
further notice or act, pay to the Administrative Agent the Cash Collateral Required Amount, which
funds shall be deposited to the Cash Collateral Account as security for the LC Outstandings and
(iv) exercise in respect of any and all Collateral, in addition to the other rights and remedies
provided for herein or otherwise available to the Administrative Agent, the Collateral Agent or the
Lenders, all the rights and remedies of a secured party on default under the Uniform Commercial
Code in effect in the State of New York and in effect in any other jurisdiction in which Collateral
is located at that time; provided, however, that in the event of an actual or deemed entry of an
order for relief with respect to the Borrower under the Bankruptcy Code, (A) the Commitments and
the obligation of each Lender to make or Convert Loans and of any Issuing Bank to issue Letters of
Credit shall automatically be terminated, (B) the principal amount outstanding hereunder, all such
interest and all such amounts shall automatically become and be due and payable, without
presentment, demand, protest or any notice of any kind, all of which are hereby expressly waived by
the Borrower, and (C) the Administrative Agent shall make demand on the Borrower to pay, and the
Borrower shall be obligated to, upon such demand without any further notice or act, pay to the
Administrative Agent the Cash Collateral Required Amount, which funds shall be deposited to the
Cash Collateral Account as security for the LC Outstandings. Notwithstanding anything to the
contrary contained herein, no notice given or declaration made by the Administrative Agent pursuant
to this Section 9.02 shall affect (i) the obligation of any Issuing Bank to make any payment under
any Letter of Credit issued by such Issuing Bank in accordance with the terms of such Letter of
Credit or (ii) the participatory interest of each Lender in each such payment. If at any time
while any Event of Default is continuing, the Administrative Agent determines that the Cash
Collateral Required Amount is greater than zero, the Administrative Agent may make demand on the
Borrower to pay, and the Borrower will be obligated to, upon such demand without any further notice
or act, pay to the Administrative Agent the Cash Collateral Required Amount, which funds shall be
deposited to the Cash Collateral Account as security for the LC Outstandings.

ARTICLE X

THE AGENTS

SECTION 10.01. Authorization and Action.

(a) Each of the Lenders and each of the Issuing Banks hereby irrevocably appoints each Agent
(other than the Syndication Agent and the Documentation Agents) as its agent and authorizes each
such Agent to take such actions on its behalf and to exercise such powers as are delegated to such
Agent by the terms of the Loan Documents, together with such actions and powers as are reasonably
incidental thereto.

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

(c) No Agent shall have any duties or obligations except those expressly set forth in the Loan
Documents. Without limiting the generality of the foregoing, (i) no Agent shall be subject to any
fiduciary or other implied duties, regardless of whether a Default or an Event of Default has
occurred and is continuing, (ii) no Agent shall have any duty to take any discretionary action or
exercise any discretionary powers, except discretionary rights and powers expressly contemplated by
the Loan Documents that such Agent is required to exercise in writing by the Required Lenders (or
such other number or percentage of the Lenders as shall be necessary under the circumstances as
provided in Section 11.01), and (iii) except as expressly set forth in the Loan Documents, no Agent
shall have any duty to disclose, or shall be liable for the failure to disclose, any information
relating to the Borrower or any of its Subsidiaries or Affiliates that is communicated to or
obtained by the Lender serving as such Agent or any of its Affiliates in any capacity. No Agent
shall be liable for any action taken or not taken by it with the consent or at the request of the
Required Lenders (or such other number or percentage of the Lenders as shall be necessary under the
circumstances as provided in Section 11.01 or any other provision of this Agreement) or in the
absence of its own gross negligence or willful misconduct. Each Agent shall be deemed not to have
knowledge of any Default or Event of Default unless and until written notice thereof is given to
such Agent by the Borrower or a Lender (in which case such Agent shall promptly give a copy of such
written notice to the Lenders and the other Agents). No Agent shall be responsible for or have any
duty to ascertain or inquire into (A) any statement, warranty or representation made in or in
connection with any Loan Document, (B) the contents of any certificate, report or other document
delivered thereunder or in connection therewith, (C) the performance or observance of any of the
covenants, agreements or other terms or conditions set forth in any Loan Document, (D) the
validity, enforceability, effectiveness or genuineness of any Loan Document or any other agreement,
instrument or document, or (E) the satisfaction of any condition set forth in Article VI or
elsewhere in any Loan Document, other than to confirm receipt of items expressly required to be
delivered to such Agent. Neither the Syndication Agent nor the Documentation Agents shall have any
duties or obligations in such capacity under any of the Loan Documents.

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

(e) Each Agent may perform any and all its duties and exercise its rights and powers by or
through one or more sub-agents appointed by such Agent. Each Agent and any such sub-agent may
perform any and all its duties and exercise its rights and powers through their respective Related
Parties. The exculpatory provisions of the preceding subsections of this Section 10.01 shall apply
to any such sub-agent and to the Related Parties of each Agent and any such sub-agent, and shall
apply to their respective activities in connection with the syndication of the credit facilities
provided for herein as well as activities as an Agent.

(f) Subject to the appointment and acceptance of a successor Agent as provided in this
subsection (f), any Agent may resign at any time by notifying the Lenders, the Issuing Banks and
the Borrower. Upon any such resignation, the Required Lenders shall have the right, in
consultation with the Borrower, to appoint a successor. If no successor shall have been so
appointed by the Required Lenders and shall have accepted such appointment within 30 days after the
retiring Agent gives notice of its resignation, then the retiring Agent may, on behalf of the
Lenders and the Issuing Banks, appoint a successor Agent which shall be a Lender with an office in
New York, New York, or an Affiliate of any such Lender. Upon the acceptance of its appointment as
an Agent hereunder by a successor, such successor shall succeed to and become vested with all the
rights, powers, privileges and duties of the retiring Agent, and the retiring Agent shall be
discharged from its duties and obligations hereunder. The fees payable by the Borrower to a
successor Agent shall be the same as those payable to its predecessor unless otherwise agreed
between the Borrower and such successor. After an Agent’s resignation hereunder, the provisions of
this Article and Section 11.04 shall continue in effect for the benefit of such retiring Agent, its
sub-agents and their respective Related Parties in respect of any actions taken or omitted to be
taken by any of them while it was acting as an Agent.

(g) Each Lender acknowledges that it has independently and without reliance upon any Agent or
any other Lender and based on such documents and information as it has deemed appropriate, made its
own credit analysis and decision to enter into this Agreement. Each Lender also acknowledges that
it will, independently and without reliance upon any Agent or any other Lender and based on such
documents and information as it shall from time to time deem appropriate, continue to make its own
decisions in taking or not taking action under or based upon this Agreement, any other Loan
Document or any related agreement or any document furnished hereunder or thereunder. Each Lender
agrees (except as provided in Section 11.05) that it will not take any legal action, nor institute
any actions or proceedings, against the Borrower or any other obligor hereunder or with respect to
any Collateral, without the prior written consent of the Required Lenders. Without limiting the
generality of the foregoing, no Lender may accelerate or otherwise enforce its portion of the
Loans, or unilaterally terminate its Commitment except in accordance with Section 9.02.

(h) Each Lender acknowledges and agrees that neither such Lender, nor any of its Affiliates,
participants or assignees, may rely on the Administrative Agent to carry out such Lender’s,
Affiliate’s, participant’s or assignee’s customer identification program, or other obligations
required or imposed under or pursuant to the USA Patriot Act or the regulations thereunder,
including the regulations contained in 31 C.F.R. 103.121 (as hereafter amended or replaced, the
“CIP Regulations”), or any other applicable laws, rules, regulations or orders of any
governmental authority, including any programs involving any of the following items relating to or
in connection with any of the Borrower, its Subsidiaries, its Affiliates or their agents, the Loan
Documents or the transactions hereunder or contemplated hereby: (a) any identity verification
procedures, (b) any recordkeeping, (c) comparisons with government lists, (d) customer notices or
(e) other procedures required under the CIP Regulations or such other laws, rules, regulations or
orders.

(i) Within 10 days after the Closing Date and at such other times as are required under the
USA Patriot Act, each Lender and each of its assignees and participants that are not incorporated
under the laws of the United States of America or a state thereof (and is not excepted from the
certification requirement contained in Section 313 of the USA Patriot Act and the applicable
regulations because it is both (a) an affiliate of a depository institution or foreign bank that
maintains a physical presence in the United States or foreign country, and (b) subject to
supervision by a banking authority regulating such affiliated depository institution or foreign
bank) shall deliver to the Administrative Agent the certification, or, if applicable,
recertification, certifying that such Lender is not a “shell” and certifying to other matters as
required by Section 313 of the USA Patriot Act and the applicable regulations.

SECTION 10.02. Indemnification. The Lenders agree to indemnify each Agent (to the extent not
reimbursed by the Borrower), ratably according to the respective Percentages of the Lenders, from
and against any and all liabilities, obligations, losses, damages, penalties, actions, judgments,
suits, costs, expenses or disbursements of any kind or nature whatsoever which may be imposed on,
incurred by, or asserted against such Agent in any way relating to or arising out of this Agreement
or any action taken or omitted by such Agent under this Agreement, provided that no Lender shall be
liable for any portion of such liabilities, obligations, losses, damages, penalties, actions,
judgments, suits, costs, expenses or disbursements resulting from such Agent’s gross negligence or
willful misconduct. Without limitation of the foregoing, each Lender agrees to reimburse the
Agents and the Arrangers promptly upon demand for its ratable share of any out-of-pocket expenses
(including counsel fees) incurred by the Agents and the Arrangers in connection with the
preparation, syndication, execution, delivery, administration, modification, amendment or
enforcement (whether through negotiations, legal proceedings or otherwise) of, or legal advice in
respect of rights or responsibilities under, this Agreement to the extent that the Agents and the
Arrangers are entitled to reimbursement for such expenses pursuant to Section 11.04 but are not
reimbursed for such expenses by the Borrower.

SECTION 10.03. Concerning the Collateral and the Loan Documents.

(a) Each Lender and Issuing Bank authorizes and directs the Collateral Agent to enter into the
Loan Documents relating to the Collateral for the benefit of the Lenders and the Issuing Banks.
Each Lender and Issuing Bank agrees that any action taken by any Agent or the Required Lenders (or,
where required by the express terms of this Agreement, a greater proportion of the Lenders) in
accordance with the provisions of this Agreement or the other Loan Documents, and the exercise by
any Agent or the Required Lenders (or, where so required, such greater proportion) of the powers
set forth herein or therein, together with such other powers as are reasonably incidental thereto,
shall be authorized and binding upon all of the Lenders and the Issuing Banks. Without limiting
the generality of the foregoing, the Collateral Agent shall have the sole and exclusive right and
authority to (i) act as the disbursing and collecting agent for the Lenders and the Issuing Banks
with respect to all payments and collections arising in connection with this Agreement and the Loan
Documents relating to the Collateral; (ii) execute and deliver each Loan Document relating to the
Collateral and accept delivery of each such agreement delivered by the Borrower, including any
intercreditor agreement referenced in Section 8.02(a)(xiii); (iii) act as collateral agent for the
Lenders and the Issuing Banks for purposes of the perfection of all Liens created by such
agreements and all other purposes stated therein; provided, however, the Collateral Agent hereby
appoints, authorizes and directs the other Agents, the Lenders and the Issuing Banks to act as
collateral sub-agent for the Collateral Agent, the Lenders and the Issuing Banks for purposes of
the perfection of all Liens with respect to any property of the Borrower or any of its Subsidiaries
at any time in the possession of such Agent, such Lender or such Issuing Bank, including, without
limitation, deposit accounts maintained with, and cash held by, such Agent, such Lender or such
Issuing Bank; (iv) manage, supervise and otherwise deal with the Collateral; (v) take such action
as is necessary or desirable to maintain the perfection and priority of the Liens created or
purported to be created by the Loan Documents; and (vi) except as may be otherwise specifically
restricted by the terms of this Agreement or any other Loan Document, exercise all remedies given
to the Collateral Agent, the Lenders or the Issuing Banks with respect to the Collateral under the
Loan Documents relating thereto, applicable law or otherwise.

(b) The Administrative Agent, each Lender and each Issuing Bank hereby directs, in accordance
with the terms of this Agreement, the Collateral Agent to release any Lien held by the Collateral
Agent for the benefit of the Lenders and the Issuing Banks:

(i) against all of the Collateral, upon payment in full of the Obligations under the
Loan Documents and termination of this Agreement;

(ii) against all of the Collateral (other than the “Collateral” under (and as defined
in) the Cash Collateral Agreement), upon satisfaction of the conditions set forth in Section
8.01(n)(ii);

(iii) against any part of the Collateral sold or disposed of by the Borrower, if such
sale or disposition is otherwise permitted under this Agreement, as certified to the
Collateral Agent by the Borrower, or is otherwise consented to by the Required Lenders;

(iv) against any part of the “Collateral” (as defined in the Cash Collateral Agreement)
to the extent required pursuant to the Cash Collateral Agreement; and/or

(v) against any of the Collateral upon the occurrence of any event described in Section
8.10 of the Borrower Pledge Agreement.

The Administrative Agent, each Lender and each Issuing Bank hereby directs the Collateral Agent to
execute and deliver or file such termination and partial release statements and do such other
things as are necessary to release Liens to be released pursuant to this Section 10.03(b) promptly
upon the effectiveness of any such release.

(c) Each Lender and each Issuing Bank hereby directs the Administrative Agent and the
Collateral Agent to, upon the satisfaction of the conditions precedent set forth in Section 6.01,
(i) release the Guarantors (as defined in the Existing Credit Agreement) from, and terminate, the
Guaranty (as defined in the Existing Credit Agreement), (ii) release Enterprises and the Grantors
(as defined in the Existing Credit Agreement) from, release all Liens granted pursuant to and
terminate the Subsidiary Pledge Agreement (as defined in the Existing Credit Agreement) and (iii)
release any Lien held by the Collateral Agent for the benefit of the Lenders and the Issuing Banks
in any assets of the Borrower other than the capital stock of Consumers and related property
pledged by the Borrower pursuant to the Borrower Pledge Agreement.

the rights or duties of any Issuing Bank under this Agreement or any other Loan Document. Any

addressed to the Administrative Agent.

SECTION 11.03. No Waiver of Remedies. No failure on the part of the Borrower, any Lender, any
Issuing Bank or any Agent to exercise, and no delay in exercising, any right hereunder or under any
other Loan Document shall operate as a waiver thereof; nor shall any single or partial exercise of
any such right preclude any other or further exercise thereof or the exercise of any other right.
The remedies herein provided are cumulative and not exclusive of any remedies provided by law.

SECTION 11.04. Costs, Expenses and Indemnification.

(a) The Borrower agrees to (i) reimburse on demand all reasonable costs and expenses of each
Agent and each Arranger (including reasonable fees and expenses of counsel to the Agents) in
connection with (A) the preparation, syndication, negotiation, execution and delivery of the Loan
Documents and (B) the care and custody of any and all collateral, and any proposed modification,
amendment, or consent relating to any Loan Document, and (ii) to pay on demand all reasonable costs
and expenses of each Agent and, on and after the date upon which the principal amount outstanding
hereunder becomes or is declared to be due and payable pursuant to Section 9.02 or an Event of
Default specified in Section 9.01(a) shall have occurred and be continuing, each Lender (including
fees and expenses of counsel to the Agents, special Michigan counsel to the Lenders and, from and
after such date, counsel for each Lender (including the allocated costs and expenses of in-house
counsel)) in connection with the workout, restructuring or enforcement (whether through
negotiations, legal proceedings or otherwise) of this Agreement, the other Loan Documents and the
other documents to be delivered hereunder.

(b) The Borrower agrees to indemnify each Agent, each Arranger, each Issuing Bank, each
Lender, and each Related Party of any of the foregoing Persons (each such Person being called an
“Indemnified Person”) against, and hold each Indemnified Person harmless from, any and all losses,
claims, damages, liabilities and related expenses, including the reasonable fees, charges and
disbursements of any counsel for any Indemnified Person, incurred by or asserted against any
Indemnified Person arising out of, in connection with, or as a result of (i) the execution or
delivery of any Loan Document or any other agreement or instrument contemplated hereby or thereby,
the performance by the parties to the Loan Documents of their respective obligations thereunder or
the consummation of the transactions contemplated hereby or thereby, (ii) any Loan or other
Extension of Credit or the use or proposed use of the proceeds therefrom, (iii) any actual or
alleged presence or release of any Hazardous Substance on or from any property owned or operated by
the Borrower or any of its Subsidiaries, or any Environmental Liability related in any way to the
Borrower or any of its Subsidiaries, (iv) the use of the Platform as contemplated herein, or (v)
any actual or prospective claim, litigation, investigation or proceeding relating to any of the
foregoing, whether based on contract, tort or any other theory and regardless of whether any
Indemnified Person is a party thereto; provided, that such indemnity shall not, as to any
Indemnified Person, be available to the extent that such losses, claims, damages, liabilities or
related expenses are determined by a court of competent jurisdiction by final and nonappealable
judgment to have resulted from the gross negligence or willful misconduct of such Indemnified
Person. The Borrower shall pay any civil penalty or fine assessed by the Office of Foreign Assets
Control against any Indemnified Person and all reasonable costs and expenses (including reasonable
fees and expenses of counsel to such Indemnified Persons) incurred in connection with defense
thereof, as a result of acts or omissions of the Borrower contrary to the representation made in
Section 7.01(t).

(c) The Borrower’s other obligations under this Section 11.04 shall survive the repayment of
all amounts owing to the Lenders, the Issuing Banks and the Agents under the Loan Documents and the
termination of the Commitments. If and to the extent that the obligations of the Borrower under
this Section 11.04 are unenforceable for any reason, the Borrower agrees to make the maximum
contribution to the payment and satisfaction thereof which is permissible under applicable law.

(d) To the extent permitted by applicable law, the Borrower shall not assert, and the Borrower
hereby waives, any claim against each Lender, each Agent and their respective Affiliates,
directors, employees, attorneys, agents or sub-agents, on any theory of liability, for special,
indirect, consequential or punitive damages (as opposed to direct or actual damages) (whether or
not the claim therefor is based on contract, tort or duty imposed by any applicable legal
requirement) arising out of, in connection with, arising out of, as a result of, or in any way
related to, this Agreement or any Loan Document or any agreement or instrument contemplated hereby
or thereby or referred to herein or therein, the transactions contemplated hereby or thereby, any
Borrowing or the use of the proceeds thereof or any act or omission or event occurring in
connection therewith, and the Borrower hereby waives, releases and agrees not to sue upon any such
claim or any such damages, whether or not accrued and whether or not known or suspected to exist in
its favor.

SECTION 11.05. Right of Set-off.

(a) Upon (i) the occurrence and during the continuance of any Event of Default and (ii) the
making of the request or the granting of the consent specified by Section 9.02 to authorize the
Administrative Agent to declare the principal amount outstanding hereunder to be due and payable
pursuant to the provisions of Section 9.02, each Lender and Issuing Bank is hereby authorized at
any time and from time to time, to the fullest extent permitted by law, to set off and apply any
and all deposits (general or special, time or demand, provisional or final) at any time held and
other indebtedness at any time owing by such Lender or such Issuing Bank, as applicable, to or for
the credit or the account of the Borrower, against any and all of the obligations of the Borrower
now or hereafter existing under this Agreement and the Promissory Notes held by such Lender or the
Issuing Bank Agreement to which such Issuing Bank is a party, as the case may be, irrespective of
whether or not such Lender or such Issuing Bank, as applicable, shall have made any demand under
this Agreement or such Promissory Notes or such Issuing Bank Agreement, as the case may be, and
although such obligations may be unmatured. Each Lender and Issuing Bank agrees to notify promptly
the Borrower after any such set-off and application made by such Lender or Issuing Bank, as the
case may be, provided that the failure to give such notice shall not affect the validity of such
set-off and application. The rights of each Lender and Issuing Bank under this Section 11.05 are
in addition to other rights and remedies (including other rights of set-off) which such Lender and
Issuing Bank may have.

(b) The Borrower agrees that it shall have no right of off-set, deduction or counterclaim in
respect of its obligations hereunder, and that the obligations of the Lenders hereunder are several
and not joint. Nothing contained herein shall constitute a relinquishment or waiver of the
Borrower’s rights to any independent claim that the Borrower may have against any Agent or any
Lender for such Agent’s or such Lender’s, as the case may be, gross negligence or willful
misconduct, but no Lender shall be liable for any such conduct on the part of any Agent or any
other Lender, and no Agent shall be liable for any such conduct on the part of any Lender or any
other Agent.

SECTION 11.06. Binding Effect. This Agreement shall become effective when it shall have been
executed by the Borrower and the Agents and when the Administrative Agent shall have been notified
by each Bank that such Bank has executed it and thereafter shall be binding upon and inure to the
benefit of the Borrower, the Agents and each Lender and their respective successors and assigns,
except that, the Borrower shall not have the right to assign its rights hereunder or any interest
herein without the prior written consent of the Lenders.

SECTION 11.07. Assignments and Participation.

(a) Any Lender may sell participations in all or a portion of its rights and obligations under
this Agreement pursuant to subsection (b) below and any Lender may assign all or any part of its
rights and obligations under this Agreement pursuant to subsection (c) below.

(b) Any Lender may sell participations to one or more banks or other entities (each a
“Participant”) in all or a portion of its rights and obligations under this Agreement (including,
without limitation, all or a portion of its Commitment and its outstanding Loan), provided that (i)
such Lender’s obligations under this Agreement (including, without limitation, its Commitment to
the Borrower hereunder) shall remain unchanged, (ii) such Lender shall remain solely responsible to
the other parties hereto for the performance of such obligations, (iii) such Lender shall remain
the holder of the Loans of such Lender for all purposes of this Agreement and (iv) the Borrower
shall continue to deal solely and directly with such Lender in connection with such Lender’s rights
and obligations under this Agreement. Each Lender shall retain the sole right to approve, without
the consent of any Participant, any amendment, modification or waiver of any provision of the Loan
Documents other than any amendment, modification or waiver with respect to any Loan or Commitment
in which such Participant has an interest which would require consent of all of the Lenders
pursuant to the terms of Section 11.01 or of any other Loan Document. The Borrower agrees that
each Participant shall be deemed to have the right of set-off provided in Section 11.05 in respect
of its participating interest in amounts owing under the Loan Documents to the same extent as if
the amount of its participating interest were owing directly to it as a Lender under the Loan
Documents, provided that each Lender shall retain the right of set-off provided in Section 11.05
with respect to the amount of participating interests sold to each Participant. The Lenders agree
to share with each Participant, and each Participant, by exercising the right of set-off provided
in Section 11.05, agrees to share with each Lender, any amount received pursuant to the exercise of
its right of set-off, such amounts to be shared in accordance with Section 11.05 as if each
Participant were a Lender. The Borrower further agrees that each Participant shall be entitled to
the benefits of Sections 5.04 and 5.06 to the same extent as if it were a Lender and had acquired
its interest by assignment pursuant to Section 11.07(c); provided that (i) a Participant shall not
be entitled to receive any greater payment under Section 5.04 or 5.06 than the Lender who sold the
participating interest to such Participant would have received had it retained such interest for
its own account, unless the sale of such interest to such Participant is made with the prior
written consent of the Borrower, and (ii) any Participant not incorporated under the laws of the
United States of America or any State thereof agrees to comply with the provisions of Section 5.06
to the same extent as if it were a Lender.

(c) Any Lender may, in the ordinary course of its business and in accordance with applicable
law, with the consent of the Administrative Agent and each Issuing Bank (such consent not to be
unreasonably withheld or delayed), at any time assign to any other Lender or to any Eligible Bank
all or any part of its rights and obligations under this Agreement, provided, that the aggregate of
the Commitments and the principal amount the Loans subject to any such assignment (other than
assignments to a Federal Reserve Bank, or to any other Lender, or to any direct or indirect
contractual counterparties in swap agreements relating to the Loans to the extent required in
connection with the physical settlement of any Lender’s obligations pursuant thereto) shall be
$5,000,000 (or such lesser amount consented to by the Administrative Agent); provided, that, unless
such Lender is assigning all of its rights and obligations hereunder, after giving effect to such
assignment the assigning Lender shall have Commitments and Loans in the aggregate of not less than
$5,000,000 (unless otherwise consented to by the Administrative Agent).

(d) Any Lender may, in connection with any sale or participation or proposed sale or
participation pursuant to this Section 11.07 disclose to the purchaser or Participant or proposed
purchaser or Participant any information relating to the Borrower furnished to such Lender by or on
behalf of the Borrower, provided that prior to any such disclosure of non-public information, the
purchaser or Participant or proposed purchaser or Participant (which Participant is not an
affiliate of a Lender) shall agree to preserve the confidentiality of any confidential information
(except any such disclosure as may be required by law or regulatory process) relating to the
Borrower received by it from such Lender.

(e) Assignments under this Section 11.07 shall be made pursuant to an agreement (a “Lender
Assignment”) substantially in the form of Exhibit F hereto or in such other form as may be agreed
to by the parties thereto and shall not be effective until a $3,500 fee has been paid to the
Administrative Agent by the assignee, which fee shall cover the cost of processing such assignment,
provided, that such fee shall not be incurred in the event of an assignment by any Lender of all or
a portion of its rights under this Agreement to (i) a Federal Reserve Bank, (ii) a Lender (iii) an
affiliate of the assigning Lender (which affiliate shall be an Eligible Bank) or (iv) to any direct
or indirect contractual counterparties in swap agreements relating to the Loans to the extent
required in connection with the physical settlement of any Lender’s obligations pursuant thereto.

(f) Notwithstanding anything to the contrary contained herein, any Lender (a “Granting
Lender”) may grant to a special purpose funding vehicle (an “SPC”), identified as such in writing
from time to time by the Granting Lender to the Administrative Agent and the Borrower, the option
to provide to the Borrower all or any part of any Loan that such Granting Lender is obligated to
make to the Borrower pursuant to this Agreement; provided that (i) nothing herein shall constitute
a commitment by any SPC to make any Loan, (ii) if an SPC elects not to exercise such option or
otherwise fails to provide all or any part of such Loan, the Granting Lender shall remain obligated
to make such Loan pursuant to the terms hereof, (iii) the Borrower shall not be required to pay any
amount under Section 5.06 that is greater than the amount which it would have been required to pay
had there been no grant to an SPC and (iv) any SPC (or assignee of an SPC) will comply, if
applicable, with the provisions contained in Section 5.06. No grant by any Granting Lender to an
SPC agreeing to provide a Loan or the making of such Loan by such SPC shall operate to relieve such
Granting Lender of its liabilities and obligations hereunder, except to the extent of the making of
such Loan by such SPC. The making of a Loan by an SPC hereunder shall utilize the Commitment of
the Granting Lender to the same extent, and as if, such Loan were made by such Granting Lender.
Each party hereto hereby agrees that no SPC shall be liable for any indemnity or similar payment
obligation under this Agreement (all liability for which shall remain with the Granting Lender).
In addition, each party hereto hereby agrees (which agreement shall survive the termination of this
Agreement) that any SPC may (i) with notice to, but without the prior written consent of, the
Borrower and the Administrative Agent and without paying any processing fee therefor, assign all or
a portion of its interests in any Loans to the Granting Lender or to any financial institutions
(consented to by the Administrative Agent in its sole discretion) providing liquidity and/or credit
support to or for the account of such SPC to support the funding or maintenance of Loans and (ii)
disclose on a confidential basis any non-public information relating to the Loans to any rating
agency, commercial paper dealer or provider of any surety, guarantee or credit or liquidity
enhancement to such SPC. This Section 11.07(f) may not be amended without the written consent of
any SPC that holds an option to provide Loans. No recourse under any obligation, covenant, or
agreement of the SPC contained in this Agreement shall be had against any shareholder, officer,
agent or director of the SPC as such, by the enforcement of any assessment or by any proceeding, by
virtue of any statute or otherwise; it being expressly agreed and understood that this Agreement is
a corporate obligation of the SPC and no personal liability shall attach to or be incurred by any
officer, agent or member of the SPC as such, or any of them under or by reason of any of the
obligations, covenants or agreements of the SPC contained in this Agreement, or implied therefrom,
and that any and all personal liability for breaches by the SPC of any such obligations, covenants
or agreements, either at law or by statute or constitution, of every such shareholder, officer,
agent or director is hereby expressly waived by all parties to this Agreement as a condition of and
consideration for the SPC entering into this Agreement; provided, however, that the foregoing shall
not relieve any such person or entity of any liability they might otherwise have as a result of
fraudulent actions or omissions taken by them. All parties to this Agreement acknowledge and agree
that the SPC shall only be liable for any claims that each of them may have against the SPC only to
the extent of the SPC’s assets. The provisions of this clause shall survive the termination of
this Agreement.

(g) Any Lender may at any time pledge or assign a security interest in all or any portion of
its rights under this Agreement to secure obligations of such Lender, including without limitation
any pledge or assignment to secure obligations to a Federal Reserve Bank; provided, that no such
pledge or assignment shall release such Lender from any of its obligations hereunder or substitute
any such pledgee or assignee for such Lender as a party hereto.

(h) The Administrative Agent shall maintain at its address referred to in Section 11.02 a copy
of each Lender Assignment and each Assumption and Acceptance delivered to and accepted by it and a
register for the recordation of the names and addresses of the Lenders and the Commitment of, and
principal amount of the Loans owing to, each Lender from time to time (the “Register”). The
entries in the Register shall be conclusive and binding for all purposes, absent manifest error,
and the Borrower, the Agents, the Issuing Banks and the Lenders may treat each Person whose name is
recorded in the Register as a Lender hereunder for all purposes of this Agreement. The Register
shall be available for inspection by the Borrower, any Issuing Bank or any Lender at any reasonable
time and from time to time upon reasonable prior notice.

SECTION 11.08. Confidentiality. In connection with the negotiation and administration of this
Agreement and the other Loan Documents, the Borrower has furnished and will from time to time
furnish to the Agents, the Issuing Banks and the Lenders (each, a “Recipient”) written information
which is identified to the Recipient when delivered as confidential (such information, other than
any such information which (i) was publicly available, or otherwise known to the Recipient, at the
time of disclosure, (ii) subsequently becomes publicly available other than through any act or
omission by the Recipient or (iii) otherwise subsequently becomes known to the Recipient other than
through a Person whom the Recipient knows to be acting in violation of his or its obligations to
the Borrower, being hereinafter referred to as “Confidential Information”). The Recipient will not
knowingly disclose any such Confidential Information to any third party (other than to those
persons who have a confidential relationship with the Recipient), and will take all reasonable
steps to restrict access to such information in a manner designed to maintain the confidential
nature of such information, in each case until such time as the same ceases to be Confidential
Information or as the Borrower may otherwise instruct. It is understood, however, that the
foregoing will not restrict the Recipient’s ability to freely exchange such Confidential
Information with its Affiliates, prospective Participants in or assignees of the Recipient’s
position herein or direct or indirect counterparties (or their advisors) to any swap,
securitization or derivative transaction relating to the Obligations, but the Recipient’s ability
to so exchange Confidential Information shall be conditioned upon any such Person entering into an
agreement as to confidentiality similar to this Section 11.08. It is further understood that the
foregoing will not prohibit the disclosure of any or all Confidential Information if and to the
extent that such disclosure may be required (1) by a regulatory agency, self-regulatory body or
otherwise in connection with an examination of the Recipient’s records by appropriate authorities,
(2) pursuant to court order, subpoena or other legal process or in connection with any proceeding,
suit or other action relating to any Loan Document or (3) otherwise, as required by law; in the
event of any required disclosure under clause (2) or (3), above, the Recipient agrees to use
reasonable efforts to inform the Borrower as promptly as practicable to the extent not prohibited
by law. Notwithstanding any other provision of this Agreement, each party (and each Participant
pursuant to Section 11.07) (and each employee, representative or other agent of such party (or
Participant)) may disclose to any and all persons, without limitation of any kind, the U.S. tax
treatment and U.S. tax structure of the transactions contemplated by the Loan Documents and all
materials of any kind (including opinions or other tax analyses) that are provided to such party
relating to such U.S. tax treatment and U.S. tax structure, other than any information for which
nondisclosure is reasonably necessary in order to comply with applicable securities laws.

SECTION 11.09. Waiver of Jury Trial. THE BORROWER, THE AGENTS, THE ISSUING BANKS AND THE
LENDERS EACH HEREBY IRREVOCABLY WAIVES ALL RIGHT TO TRIAL BY JURY IN ANY ACTION, PROCEEDING OR
COUNTERCLAIM ARISING OUT OF OR RELATING TO THIS AGREEMENT OR ANY OTHER LOAN DOCUMENT, OR ANY OTHER
INSTRUMENT OR DOCUMENT DELIVERED HEREUNDER OR THEREUNDER.

SECTION 11.10. GOVERNING LAW; SUBMISSION TO JURISDICTION. THIS AGREEMENT AND THE PROMISSORY
NOTES SHALL BE GOVERNED BY, AND CONSTRUED IN ACCORDANCE WITH, THE LAWS OF THE STATE OF NEW YORK
(INCLUDING SECTION 5-1401 OF THE GENERAL OBLIGATIONS LAWS OF THE STATE OF NEW YORK, BUT OTHERWISE
WITHOUT REGARD TO CONFLICTS OF LAW PRINCIPLES). THE BORROWER, THE LENDERS, THE ISSUING BANKS AND
THE AGENTS, EACH (I) IRREVOCABLY SUBMITS TO THE JURISDICTION OF ANY NEW YORK STATE COURT OR FEDERAL
COURT SITTING IN NEW YORK CITY IN ANY ACTION ARISING OUT OF ANY LOAN DOCUMENT, (II) AGREES THAT ALL
CLAIMS IN SUCH ACTION MAY BE DECIDED IN SUCH COURT, (III) WAIVES, TO THE FULLEST EXTENT IT MAY
EFFECTIVELY DO SO, THE DEFENSE OF AN INCONVENIENT FORUM AND (IV) CONSENTS TO THE SERVICE OF PROCESS
BY MAIL. A FINAL JUDGMENT IN ANY SUCH ACTION SHALL BE CONCLUSIVE AND MAY BE ENFORCED IN OTHER
JURISDICTIONS. NOTHING HEREIN SHALL AFFECT THE RIGHT OF ANY PARTY TO SERVE LEGAL PROCESS IN ANY
MANNER PERMITTED BY LAW OR AFFECT ITS RIGHT TO BRING ANY ACTION IN ANY OTHER COURT. THE BORROWER
AGREES THAT THE AGENTS SHALL HAVE THE RIGHT TO PROCEED AGAINST THE BORROWER OR ITS PROPERTY IN A
COURT IN ANY LOCATION TO ENABLE THE AGENTS, THE ISSUING BANKS AND THE LENDERS TO REALIZE ON THE
COLLATERAL OR ANY OTHER SECURITY FOR THE OBLIGATIONS, OR TO ENFORCE A JUDGMENT OR OTHER COURT ORDER
ENTERED IN FAVOR OF ANY AGENT, ANY ISSUING BANK OR ANY LENDER. THE BORROWER AGREES THAT IT WILL
NOT ASSERT ANY PERMISSIVE COUNTERCLAIMS IN ANY PROCEEDING BROUGHT BY ANY AGENT, ANY ISSUING BANK OR
ANY LENDER TO REALIZE ON THE COLLATERAL OR ANY OTHER SECURITY FOR THE OBLIGATIONS, OR TO ENFORCE A
JUDGMENT OR OTHER COURT ORDER IN FAVOR OF ANY AGENT, ANY ISSUING BANK OR ANY LENDER. THE BORROWER
WAIVES ANY OBJECTION THAT IT MAY HAVE TO THE LOCATION OF THE COURT IN WHICH ANY AGENT, ANY ISSUING
BANK OR ANY LENDER MAY COMMENCE A PROCEEDING DESCRIBED IN THIS SECTION.

SECTION 11.11. Relation of the Parties; No Beneficiary. No term, provision or requirement,
whether express or implied, of any Loan Document, or actions taken or to be taken by any party
thereunder, shall be construed to create a partnership, association, or joint venture between such
parties or any of them. No term or provision of this Agreement or any other Loan Document shall be
construed to confer a benefit upon, or grant a right or privilege to, any Person other than the
parties hereto or thereto. The Borrower hereby acknowledges that none of the Agents, the Lenders
or the Issuing Banks has any fiduciary relationship with or fiduciary 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 Agents, the Lenders and the Issuing Banks, on the one hand, and the
Borrower, on the other hand, in connection herewith or therewith is solely that of debtor and
creditor.

SECTION 11.12. Execution in Counterparts. This Agreement may be executed in any number of
counterparts and by different parties hereto in separate counterparts, each of which when so
executed shall be deemed to be an original and all of which taken together shall constitute one and
the same Agreement.

SECTION 11.13. Survival of Agreement. All covenants, agreements, representations and
warranties made herein and in the certificates pursuant hereto shall be considered to have been
relied upon by the Agents, the Lenders and the Issuing Banks and shall survive the making by the
Lenders and the Issuing Banks of the Extensions of Credit and the execution and delivery to the
Lenders of any Promissory Notes evidencing the Extensions of Credit and shall continue in full
force and effect so long as any Promissory Note or any amount due hereunder is outstanding and
unpaid, any Letter of Credit remains outstanding or any Commitment of any Lender has not been
terminated.

SECTION 11.14. Platform.

(a) The Borrower shall use its commercially reasonable best efforts to transmit to the
Administrative Agent all information, documents and other materials that it is obligated to furnish
to the Administrative Agent pursuant to this Agreement and the other Loan Documents, including,
without limitation, all notices, requests, financial statements, financial and other reports,
certificates and other information materials, but excluding any such communication that (i) relates
to a notice of borrowing or other extension of credit or a conversion of an existing interest rate
on any Loan or Borrowing (including, without limitation, any Notice of Conversion), (ii) relates to
the payment of any principal or other amount due hereunder prior to the scheduled date therefor,
(iii) provides notice of any Default or Event of Default hereunder or (iv) is required to be
delivered to satisfy any condition precedent to the effectiveness of this Agreement and/or any
Extension of Credit hereunder (all such non-excluded communications being referred to herein
collectively as “Communications”), in an electronic/soft medium in a format reasonably acceptable
to the Administrative Agent to oploanswebadmin@citigroup.com (or such other e-mail address
designated by the Administrative Agent from time to time). In addition, the Borrower shall
continue to provide the Communications to the Administrative Agent in the manner specified in this
Agreement but only to the extent requested by the Administrative Agent. Each Lender, each Issuing
Bank and the Borrower further agrees that the Administrative Agent may make the Communications
available to the Lenders and the Issuing Banks by posting the Communications on IntraLinks or a
substantially similar electronic transmission system (the “Platform”); provided, however, that upon
written notice to the Administrative Agent and the Borrower, any Lender or any Issuing Bank (such
lender a “Declining Lender”) may decline to receive Communications via the Platform and shall
direct the Borrower to provide, and the Borrower shall so provide, such Communications to such
Declining Lender by delivery to such Declining Lender’s address set forth on the signature pages
hereto, or as specified in the Lender Assignment or Assignment and Acceptance pursuant to which it
became a Lender or as otherwise directed in such notice. Subject to the conditions set forth in
the proviso in the immediately preceding sentence, nothing in this Section 11.14 shall prejudice
the right of the Administrative Agent to make the Communications available to the Lenders in any
other manner specified herein.

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

(c) Each party hereto (other than a Declining Lender) agrees that any electronic communication
referred to in this Section 11.14 shall be deemed delivered upon the posting of a record of such
communication as “sent” in the e-mail system of the sending party or, in the case of any such
communication to the Administrative Agent, upon the posting of a record of such communication as
“received” in the e-mail system of the Administrative Agent, provided that if such communication is
not so received by the Administrative Agent during the normal business hours of the Administrative
Agent, such communication shall be deemed delivered at the opening of business on the next business
day for the Administrative Agent.

(d) Each party hereto acknowledges that the distribution of material through an electronic
medium is not necessarily secure and there are confidentiality and other risks associated with such
distribution.

(e) EACH PARTY HERETO FURTHER ACKNOWLEDGES AND AGREES THAT:

(i) NONE OF THE ADMINISTRATIVE AGENT, ITS AFFILIATES NOR ANY OF THEIR RESPECTIVE
OFFICERS, DIRECTORS, EMPLOYEES, AGENTS, ADVISORS OR REPRESENTATIVES (COLLECTIVELY, THE
“CITIGROUP PARTIES”) WARRANTS THE ADEQUACY OF THE PLATFORM OR THE ACCURACY OR COMPLETENESS
OF ANY COMMUNICATIONS, AND EACH CITIGROUP PARTY EXPRESSLY DISCLAIMS LIABILITY FOR ERRORS OR
OMISSIONS IN ANY COMMUNICATIONS, AND

(ii) NO WARRANTY OF ANY KIND, EXPRESS, IMPLIED OR STATUTORY, INCLUDING, WITHOUT
LIMITATION, ANY WARRANTY OF MERCHANTABILITY, FITNESS FOR A PARTICULAR PURPOSE,
NON-INFRINGEMENT OF THIRD PARTY RIGHTS OR FREEDOM FROM VIRUSES OR OTHER CODE DEFECTS, IS
MADE BY ANY CITIGROUP PARTY IN CONNECTION WITH ANY COMMUNICATIONS OR THE PLATFORM.

(f) This Section 11.14 shall terminate on the date that neither CUSA nor any of the Citigroup
Parties is the Administrative Agent under this Agreement.

SECTION 11.15. USA Patriot Act. Each Lender hereby notifies the Borrower that pursuant to
requirements of the USA 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 Lender to identify the Borrower in accordance with the USA Patriot
Act.
