Business Day after such relevant LC Disbursement is made, payable on demand, at a rate per
annum equal to the Base Rate plus the Base Rate Margin, and

payable hereunder, from the date such amount is due and payable until the date such amount is paid
in full) than the maximum rate permitted by applicable law. Interest accrued pursuant to this
paragraph shall be for the account of the Issuing Bank, except that interest accrued on and after

the account of such Bank to the extent of such payment.

 

14

 

(b) The Company agrees to pay to the Administrative Agent for the account of the Banks ratably

a fronting fee at the rate per annum heretofore mutually agreed by the Company and the Issuing Bank
pursuant to the Fee Letter, on the Maximum Credit Amount of the Letter of Credit from and including
the Effective Date to, but excluding, the Termination Date. Such fronting fee accrued through and
including the last day of March, June, September and December of each year shall be payable in
arrears on the third Business Day following such last day, commencing on the first such date to
occur after the Effective Date. The Company agrees to pay to the Issuing Bank for its account (i)
on or before the fifth Business Day after the Issuing Bank shall have paid any drawing under the
Letter of Credit, a drawing fee (inclusive of any wire-transfer fees) in an amount equal to $135,
(ii) on or before the date of any extension of the Letter of Credit pursuant to Section 17, an
amendment fee, if any, in an amount mutually agreed upon between the Issuing Bank and the Company,
and (iii) on or before the date of any transfer of the Letter of Credit, a transfer fee, if any, in
an amount set forth on Exhibit 3 to the Letter of Credit.

(d) (i) If after April 16, 2010, the adoption of any applicable law, rule or regulation, or
any change therein, or any change in the interpretation or administration thereof by any
governmental authority, central bank or comparable agency charged with the interpretation or
administration thereof, or compliance by any Bank with any request or directive (whether or not
having the force of law) of any such authority, central bank or comparable agency shall impose,
modify or deem applicable any reserve, special deposit or similar requirement (including, without
limitation, any such requirement imposed by the Board of Governors of the Federal Reserve System)
against letters of credit issued by or assets held by, deposits with or for the account of, or
credit extended by, any Bank or shall impose on any Bank any other condition regarding this
Agreement or the Letter of Credit or its Participation therein, and the result of any of the
foregoing is to increase the cost to such Bank of the issuance or maintenance of the Letter of
Credit or its Participation therein, or to reduce the amount of any sum received or receivable by
such Bank under this Agreement with respect thereto, by an amount deemed by such Bank to be
material, then within 30 days after demand by such Bank (with a copy to the Administrative Agent),
the Company shall pay to the Administrative Agent for the account of such Bank such additional
amount or amounts as will compensate such Bank for such increased cost or reduction.

(ii) If any Bank shall have determined that, after April 16, 2010, the adoption of any
applicable law, rule or regulation regarding capital adequacy, or any change in any such
law, rule or regulation, or any change in the interpretation or administration thereof by
any governmental authority, central bank or comparable agency charged with the
interpretation or administration thereof, or any request or directive regarding capital
adequacy (whether or not having the force of law) of any such authority, central bank or

 

15

 

comparable agency, has or would have the effect of reducing the rate of return on
capital of such Bank (or its Parent) as a consequence of such Bank’s obligations hereunder
to a level below that which such Bank (or its Parent) could have achieved but for such
adoption, change, request or directive (taking into consideration its policies with respect
to capital adequacy) by an amount deemed by such Bank to be material, then from time to
time, within 30 days after demand by such Bank (with a copy to the Administrative Agent),
the Company shall pay to such Bank such additional amount or amounts as will compensate such
Bank (or its Parent) for such reduction.

(iii) Each Bank will notify the Company and the Administrative Agent of any event of
which it has knowledge, occurring after April 16, 2010 which will entitle such Bank to
compensation pursuant to clause (i) or (ii) of this Section 2(d) as promptly as practicable,
but in any event within 90 days after such Bank obtains knowledge thereof; provided that, if
such Bank fails to give such notice within 90 days after it obtains knowledge of such an
event, such Bank shall, with respect to compensation payable in respect of any costs
resulting from such event, only be entitled to payment for costs incurred on and after the
date that such Bank does give such notice. A certificate of any Bank claiming compensation
under this Section 2(d) and setting forth the additional amount or amounts to be paid to it
hereunder shall be conclusive in the absence of demonstrable error. In determining such
amount, such Bank may use any reasonable averaging and attribution methods.

(e) For the purposes of this Section 2(e), the following terms have the following meanings:

“Taxes” means any and all present or future taxes, duties, levies, imposts, deductions,

all liabilities with respect thereto, excluding (i) in the case of each Bank and the Administrative
Agent, taxes imposed on or measured by its net income, and franchise or similar taxes imposed on
it, by the United States, or by the jurisdiction (or any political subdivision thereof) under the

which its Applicable Booking Office is located, (ii) any branch profits taxes imposed by the United
States or any similar tax imposed by any other jurisdiction in which the Company is located, (iii)

Agreement.

“Other Taxes” means any present or future stamp or documentary taxes and any other excise or
property taxes, or similar charges or levies, which arise from any payment made pursuant to this
Agreement or from the execution or delivery of, or otherwise with respect to, this Agreement or the

(i) Any and all payments by the Company to or for the account of any Bank or the
Administrative Agent hereunder shall be made without deduction for any Taxes or Other Taxes;
provided that, if the Company shall be required by law to deduct any Taxes or Other Taxes
from any such payments, (A) the sum payable shall be increased as necessary so that after
making all required deductions for any Taxes or Other Taxes (including deductions applicable
to additional sums payable under this Section) such Bank or the Administrative Agent (as the
case may be) receives an amount equal to the sum it would have received had no such
deductions been made, (B) the Company shall make such deductions, (C) the Company shall pay
the full amount deducted to the relevant taxation authority or other authority in accordance
with applicable law and (D) the Company shall furnish to the Administrative Agent the

imposed or asserted by any jurisdiction on amounts payable under this Section) paid by such
Bank or the Administrative Agent (as the case may be) and any liability (including
penalties, interest and expenses) arising therefrom or with respect thereto. This
indemnification shall be paid within 30 days after such Bank or the Administrative Agent (as
the case may be) makes demand therefor. Such demand shall be made as promptly as
practicable, but in any event within 90 days after such Bank obtains actual knowledge of
such event; provided, however, that if any Bank fails to make such demand within 90 days
after such Bank obtains knowledge of such event, such Bank shall, with respect to
compensation payable in respect of such event, not be entitled to compensation in respect of
the costs and losses incurred between the 90th day after such Bank obtains actual knowledge
of such event and the date such Bank makes such demand.

(iii)

(1) Each Bank shall deliver to the Company and to the Administrative Agent, at the time
or times prescribed by applicable laws or when reasonably requested by the Company or the
Administrative Agent, such properly completed and executed documentation prescribed by
applicable laws or by the taxing authorities of any jurisdiction and such other reasonably
requested information as will permit the Company or the Administrative Agent, as the case
may be, to determine (A) whether or not payments made hereunder are subject to Taxes, (B) if
applicable, the required rate of withholding or deduction, and (C) such Bank’s entitlement
to any available exemption from, or reduction of, applicable Taxes in respect of all
payments to be made to such Bank by the Company pursuant to this Agreement or otherwise to
establish such Bank’s status for withholding tax purposes in the applicable jurisdiction.

(2) Without limiting the generality of the foregoing:

(A) any Bank that is a “United States Person” within the meaning of Section
7701(a)(30) of the Internal Revenue Code, and not an exempt recipient described in
Section 6049(b)(4) of the Internal Revenue Code, shall

 

17

 

deliver to the Company and the Administrative Agent executed originals of
Internal Revenue Service Form W-9 or such other documentation or information
prescribed by applicable laws or reasonably requested by the Company or the
Administrative Agent as will enable the Company or the Administrative Agent, as the
case may be, to determine whether or not such Bank is subject to backup withholding
or information reporting requirements; and

(B) each Bank that is organized under the laws of a jurisdiction other than the
United States (including each State thereof and the District of Columbia) (a
“Foreign Bank”) that is entitled under the Internal Revenue Code or any applicable
treaty to an exemption from or reduction of withholding tax with respect to payments
hereunder shall deliver to the Company and the Administrative Agent (in such number
of copies as shall be requested by the recipient) on or prior to the date on which
such Foreign Bank becomes a Bank under this Agreement (and from time to time
thereafter upon the request of the Company or the Administrative Agent, but only if
such Foreign Bank is legally entitled to do so), whichever of the following is
applicable

(I) executed originals of Internal Revenue Service Form W-8BEN claiming
eligibility for benefits of an income tax treaty to which the United States is a
party,

(II) executed originals of Internal Revenue Service Form W-8ECI,

(III) executed originals of Internal Revenue Service Form W-8IMY and all
required supporting documentation,

Internal Revenue Service Form W-8BEN, or

(V) executed originals of any other form prescribed by applicable laws as a
basis for claiming exemption from or a reduction in United States Federal
withholding tax together with such supplementary documentation as may be prescribed
by applicable laws to permit the Company or the Administrative Agent to determine
the withholding or deduction required to be made.

(3) Each Bank shall promptly notify the Company and the Administrative Agent of any
change in circumstances which would modify or render invalid any claimed exemption or
reduction.

 

18

 

(iv) For any period with respect to which a Bank has failed to provide the Company or
the Administrative Agent with the appropriate forms pursuant to Section 2(e)(iii) (unless
such failure is due to a change in treaty, law or regulation occurring subsequent to the
date on which such form originally was required to be provided, but only to the extent that
the Bank has complied with the law as changed by such treaty, law or regulation), such Bank
shall not be entitled to indemnification under Section 2(e)(ii) or (iii) with respect to
Taxes imposed by the United States; provided that if a Bank, which is otherwise exempt from
or subject to a reduced rate of withholding tax, becomes subject to Taxes because of its
failure to deliver a form required hereunder, the Company shall take such steps as such Bank
shall reasonably request to assist such Bank to recover such Taxes.

(v) If the Company is required to pay additional amounts to or for the account of any
Bank pursuant to this Section, then such Bank will change the jurisdiction of its Applicable
Booking Office if, in the reasonable judgment of such Bank, such change (A) will eliminate
or reduce any such additional payment which may thereafter accrue and (B) is not otherwise
materially disadvantageous to such Bank.

(f) If (x) the Company is required pursuant to Section 2(d) or 2(e) to make any additional
payment to any Bank (any Bank so affected an “Affected Bank”) or (y) any Bank becomes a Defaulting
Bank, the Company may elect to replace the Participation Percentage and Participation of such
Affected Bank or Defaulting Bank, as applicable, provided that no Reimbursement Event of Default
shall have occurred and be continuing at the time of such replacement, and provided further that,
concurrently with such replacement, (i) another bank or other entity which is reasonably
satisfactory to the Company, the Issuing Bank and the Administrative Agent shall agree, as of such
date, to purchase for cash (to the extent of the principal amount of such Affected Bank’s or
Defaulting Bank’s, as applicable, Disbursement Advances and accrued interest and fees and other
reimbursable amounts then due and payable) and otherwise assume the Participation Percentage and
Participation of, and other obligations then due to, such Affected Bank or Defaulting Bank, as
applicable, pursuant to an Assignment and Assumption and to become a Bank for all purposes under
this Agreement and to assume all obligations of such Affected Bank or Defaulting Bank, as
applicable, to be replaced as of such date and to comply with the requirements of Section 15
applicable to assignments, (ii) the Company shall pay to such Affected Bank or Defaulting Bank, as
applicable, in same day funds on the day of such replacement all interest, fees and other amounts
then accrued but unpaid to such Affected Bank or Defaulting Bank, as applicable, by the Company
hereunder to and including the date of replacement, including without limitation payments due to
such Affected Bank or Defaulting Bank, as applicable, under Sections 2(d) and 2(e), in each case to
the extent not paid by the purchasing Bank, and (iii) concurrently with the effectiveness of such
replacement, such Affected Bank or Defaulting Bank, as applicable, shall be released with respect
to its Participation Percentage, such Participation Percentage shall be terminated, and
Disbursement Advances assigned by such Affected Bank or Defaulting Bank, as applicable, and shall
cease to be a Bank hereunder but shall continue to be entitled to the benefits of, and subject to,
those provisions of this Agreement which survive payment of all amounts payable pursuant to Section
2 and termination of the Letter of Credit and this Agreement.

 

19

 

(g) The Company shall make each payment hereunder to the Administrative Agent at its Chicago
office, not later than 2:00 p.m. (New York City time) on the date when due in lawful money of the
United States of America and in Federal or other funds immediately available in Chicago. Whenever
any payment under this Section 2 shall be due on a day which is not a Business Day, the date for
payment thereof shall be extended to the next succeeding day that is a Business Day. If the date
for any payment of principal is extended by operation of law or otherwise, interest thereon shall
be payable for such extended time.

(h) Computations of the letter of credit commission, the fronting fee referred to in Section
2(c), and interest 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, for the actual number of days (including the
first day but excluding the last day) elapsed. Computations of all other interest hereunder shall
be made by the Administrative Agent on the basis of a year of 360 days for the actual number of
days (including the first day but excluding the last day) elapsed.

(i) Provided that the Company shall have delivered notice thereof to the Administrative Agent
not less than three Business Days prior to any proposed termination, the Company may terminate this
Agreement (other than those provisions which expressly survive termination hereof) upon (i) payment
in full of all amounts payable under Section 2, together with accrued and unpaid interest thereof,
(ii) cancellation and return of the Letter of Credit, and (iii) the payment in full of all
reimbursable expenses and other obligations under this Agreement together with accrued and unpaid
interest thereon. No such termination will be made unless the Equity Participant will be provided
with a substitute letter of credit as and to the extent required by the Participation Agreement at
such time or unless the Equity Participant shall otherwise consent.

(j) Notwithstanding any provision of this Agreement to the contrary, if any Bank becomes a
Defaulting Bank, then the following provisions shall apply for so long as such Bank is a Defaulting
Bank:

(i) the Company shall not be required to pay any letter of credit commission to such
Defaulting Bank pursuant to Section 2(b) with respect to such Defaulting Bank’s
Participation Percentage; provided that, without prejudice to any rights or remedies of the
Issuing Bank or any Bank hereunder, the letter of credit commission payable under Section
2(b) with respect to such Defaulting Bank’s Participation Percentage shall be payable to the
Issuing Bank until such Defaulting Lender shall cease to be a Defaulting Lender hereunder.
For the avoidance of doubt, it is being understood that, the interest payable by the Company
pursuant to Section 2(a) shall continue to be payable to the applicable Banks, including the
Defaulting Bank, to the extent the Defaulting Bank has funded its Participation Percentage
and would be entitled to such interest had it not become a Defaulting Bank;

(ii) the Participation Percentage of such Defaulting Bank shall not be included in
determining whether the Required Banks have taken or may take any action hereunder
(including any consent to any amendment or waiver pursuant to Section 10), other than any
waiver, amendment or modification requiring the consent of all Banks or of each affected
Bank;

 

20

 

(iii) for the avoidance of doubt, the Company shall retain and reserve its other rights and
remedies respecting each Defaulting Bank; and

(iv) in the event that the Administrative Agent, the Company and the Issuing Bank each
agrees that a Defaulting Bank has adequately remedied all matters that caused such Bank to
be a Defaulting Bank, then this Section 2(i) shall no longer apply in respect of such
rehabilitated Defaulting Bank.

Section 3. Amendment and Restatement of Letter of Credit; Conditions to Effectiveness; Transitional
Provisions. (a) On the terms and conditions herein set forth, the Issuing Bank agrees to execute

or agreement contained in this Agreement (other than those covered by

 

32

 

clause (i) above or subclause (A) of this clause (ii) or Section 7(e) or Section 19) on its
part to be performed or observed if the failure to perform or observe such term, covenant or

(whether by scheduled maturity, required prepayment, acceleration, demand or otherwise), and
such failure shall continue after the applicable grace period, if any, specified in the

of default shall exist under any agreement or instrument relating to any such Indebtedness

as such debts become due, or shall admit in writing its inability to pay its debts
generally, or shall make a general assignment for the benefit of creditors; or any

limitation, the entry of an order for relief against, or the appointment of a receiver,
trustee, custodian or other similar official for, it or for any substantial part of its
property) shall occur; or the Company or any of its Material Subsidiaries shall take any

respect to any Plan or Multiemployer Plan and, as a result of such event or condition,
together with all other such events or conditions, the Company or any ERISA Affiliate shall
incur or in the opinion of the Required Banks shall be reasonably likely to incur a

which is, in the determination of the Required Banks, likely to exceed $35,000,000 in the
aggregate; or

of Credit as provided therein. The Administrative Agent shall give notice to the Company under
Section 9(ii) promptly upon being requested to do so by the Required Banks and will promptly notify
each Bank of any such notice given at the request of the Required Banks.

Section 10. Amendments and Waivers. No modification, amendment or waiver of any provision of this
Agreement or the Letter of Credit or any consent to the assignment of the Company’s obligations
under any of the Transaction Documents or the Financing Documents shall be effective unless the
same shall be in writing and signed by (or with the written consent of) the Company and the
Required Banks (and, if the rights or duties of the Issuing Bank or the Administrative Agent are
affected thereby, by it); provided that no such modification, amendment, waiver or consent shall,
unless signed by (or with the written consent of) each Bank affected thereby, (i) increase the
Maximum Credit Amount or Maximum Drawing Amount or subject any Bank to any additional obligation
under this Agreement or the Letter of Credit, (ii) reduce the principal of or rate of interest on

36

 

(d) The Platform is provided “as is” and “as available.” The Agent Parties (as defined below)
do not warrant the accuracy or completeness of the Company Materials or the adequacy of the
Platform, and expressly disclaim any liability for errors in or omissions from the Company
Materials. No warranty of any kind, express or implied or statutory, is made by any Agent Party in
connection with the Company Materials or the Platform. In no event shall the Administrative Agent,
its Affiliates, or any partners, directors, officers, employees, agents and advisors of the
Administrative Agent or of its Affiliates (collectively, the “Agent Parties”) have any liability to
the Company, any Bank or any other Person for losses, claims, damages, liabilities or expenses of
any kind (whether in tort, contract or otherwise) arising out of the Company’s or the
Administrative Agent’s transmission of Company Materials through the Internet, except to the extent
that such losses, claims, damages, liabilities or expenses are determined by a court of competent
jurisdiction by a final and nonappealable judgment to have resulted from the gross negligence or
willful misconduct of such Agent Party.

Section 12. No Waiver; Remedies. No failure on the part of the Administrative Agent or any Bank to
exercise, and no delay in exercising, any right, power, or privilege hereunder shall operate as a
waiver thereof; nor shall any single or partial exercise of any right hereunder 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 13. Waiver of Right of Setoff. The Administrative Agent and each Bank hereby waive any right to
set off and apply any and all deposits (general or special, time or demand, provisional or final)
and collateral at any time held and other indebtedness at any time owing by it to or for the credit
or the account of the Company if there shall be a drawing under the Letter of Credit at any time
during the pendency of any proceeding by or against the Company seeking to adjudicate it a bankrupt
or insolvent, or seeking liquidation, winding up, reorganization, arrangement, adjustment,
protection, relief or composition of it or its debts under any law relating to bankruptcy,
insolvency or reorganization or relief of debtors, or seeking the entry of an order for relief or
the appointment of a receiver, custodian, trustee or other similar official for it or for any
substantial part of its property (collectively the “bankruptcy events”), against any and all of the
obligations of the Company now or hereafter existing in respect of any reimbursement obligation of
the Company set forth in Section 2(a), provided that any such waiver shall be deemed ineffective as
and to the extent that the Administrative Agent and each Bank receive, after any of the bankruptcy
events occur, an unqualified opinion of nationally-recognized counsel with bankruptcy law
experience (which counsel shall be mutually satisfactory to the Administrative Agent and the Equity
Participant, each of which shall use its best efforts to agree on such counsel), that non-waiver
would not, as a result of the application of bankruptcy or similar laws as then in effect, lead to
the Administrative Agent or any Bank being refused, prevented, permanently enjoined or restrained
from or delayed in fulfilling its obligation under the Letter of Credit. This Section 13 shall not
constitute a waiver of any right of setoff if there shall be a drawing under the Letter of Credit
at any time other than that described in this Section 13.

Section 14. Participations of the Banks. (a) The Issuing Bank hereby sells to each other Bank, and each
Bank hereby severally purchases from the Issuing Bank, as of the Effective Date, a Participation in
an amount equal to such Bank’s Participation Percentage of the Letter of Credit and in each drawing
thereunder, all on the terms and conditions set forth herein. Each Bank

 

37

 

acknowledges and agrees that its obligation to acquire participations pursuant to this
paragraph in respect of the Letters of Credit is absolute and unconditional and shall not be
affected by any circumstance whatsoever, including any amendment, renewal or extension of the
Letter of Credit or the occurrence and continuance of a Reimbursement Event of Default, and that
each such payment shall be made without any offset, abatement, withholding or reduction whatsoever.

(b) If at any time on or after the Effective Date the Company shall fail to reimburse any LC
Disbursement prior to or immediately upon making thereof by the Issuing Bank, such LC Disbursement
shall constitute a Disbursement Advance in accordance with Section 2(a), and the Administrative
Agent shall promptly (but in any event no later than 2:30 p.m., New York City time, on the date
payment is due from the Banks under this Section 14(b)) advise each Bank thereof and of the amount
due from the Company and the amount of such Bank’s Participation therein, and each Bank shall pay,
no later than 4:00 p.m. (New York City time) on such date such Bank’s Participation Percentage of
such amount by transferring the same in immediately available funds to the Administrative Agent for
the account of the Issuing Bank at the Administrative Agent’s address specified in Section 11.
With respect to any such LC Disbursement, each Bank agrees that the Issuing Bank shall have no
responsibility to the Banks other than obtaining the certificates referred to in the Letter of
Credit and notifying each Bank thereof. The Administrative Agent shall promptly credit each Bank’s
account with such Bank’s Participation Percentage of (i) all amounts representing principal of, or
interest on, any Disbursement Advances, in each case in respect of which such Bank has funded its
Participation Percentage in accordance with the foregoing provisions of this Section 14(b) and (ii)
letter of credit commissions payable to each Bank pursuant to Section 2(b) of this Agreement and
accruing on and after the Effective Date, but, in the case of both clause (i) and clause (ii), only
if, when and to the extent received by the Administrative Agent from the Company. All such
payments shall be made if, when and to the extent the Administrative Agent receives payment from
the Company in respect of any Disbursement Advance and of the letter of credit commission pursuant
to Section 2(b) of this Agreement, and in the same funds in which such amounts are received, by
credit to an account at a bank located in the United States of America as each Bank shall designate
in writing to the Administrative Agent.

(c) If the Administrative Agent should for any reason make any payment to any Bank in
anticipation of the receipt of funds from the Company and such funds are not received by the
Administrative Agent from the Company on the date payment is due, then such Bank shall, on demand
by the Administrative Agent, forthwith return to the Administrative Agent any such amounts
transferred to such Bank by the Administrative Agent in respect of such Bank’s Participation plus
interest thereon from the day such amounts were transferred by the Administrative Agent to such
Bank to but not including the day such amounts are returned by such Bank at a rate per annum equal
to the Federal Funds Rate. If the Administrative Agent is required at any time to return to the
Company or to a trustee, receiver, liquidator, custodian or other similar official any portion of
the payments made by the Company to the Administrative Agent for the account of any Bank, then such
Bank shall, on demand by the Administrative Agent, forthwith return to the Administrative Agent any
such payments transferred to such Bank by the Administrative Agent in respect of such Bank’s
Participation, but without interest on such payments (unless the Administrative Agent is required
to pay interest on such amounts to the Person recovering such payments).

 

38

 

(d) Each Bank agrees that if it should receive any amount due to it under this Agreement in
respect of its Participation other than from the Administrative Agent, such Bank will remit all of
the same to the Administrative Agent to distribute to the Banks pursuant to this Agreement, and
such Bank’s Participation shall be adjusted to reflect such remittance. Each Bank further agrees
to send the Administrative Agent a copy of any notice sent by such Bank to the Company hereunder.

(e) Each Bank acknowledges and represents that it has made its own independent appraisal of
the Company, and the business, affairs and financial condition of the Company, based on such
documents and information as such Bank has deemed appropriate, and each Bank will continue to be
responsible for making its own independent appraisal of such matters, based on such documents and
information as such Bank shall deem appropriate at the time, and has not relied upon and will not
hereafter rely upon the Administrative Agent or any other Bank or any information prepared,
distributed or otherwise made available by the Administrative Agent for such appraisal or other
assessment or review of the Company. Each Bank represents, and in granting a Participation to such
Bank it is specifically understood and agreed, that such Bank is acquiring its Participation in the
Letter of Credit for its own account in the ordinary course of its commercial banking business and
not with a view to, or for sale in connection with, any distribution thereof.

Section 15. Assignees; Participants. (a) Each Bank shall have the right, with the prior written consent
of the Company (which shall not be unreasonably withheld, and shall not be required if a
Reimbursement Event of Default has occurred and is continuing) and the prior written consent of the
Administrative Agent and the Issuing Bank, to assign all or a pro rata portion of all of its rights
and obligations under its Participation at any time and from time to time to one or more Eligible
Institutions (each an “Assignee”); provided that (i) each such Assignee shall assume such rights
and obligations and agree, for the benefit of each other party hereto, to be bound by the
provisions of, and perform the obligations of a Bank under, this Agreement, pursuant to an
Assignment and Assumption and (ii) the aggregate amount of the Participation or Participations
assigned to each such Assignee pursuant to this Section 15(a) shall not be less than $5,000,000.
Each Bank shall give prompt notice to the Administrative Agent and the Company of each such
assignment made by it. For the avoidance of doubt, no assignment by JPMorgan pursuant to this
Section 15 shall affect its rights and obligations in its capacity as Issuing Bank.

(b) (i) Each Bank shall also have the right, without the consent of the Company, to grant
participating interests in its Participation at any time and from time to time to one or more other
financial institutions or other Persons (other than a natural person or the Company or any of the
Company’s Affiliates or Subsidiaries) (each a “Participant”); provided that (A) such Bank’s
obligations under this Agreement shall remain unchanged, (B) such Bank shall remain solely
responsible to the other parties hereto for the performance of such obligations and (C) the
Company, the Administrative Agent and the other Banks shall continue to deal solely and directly
with such Bank in connection with such Bank’s rights and obligations under this Agreement. Each
such participation granted by a Bank shall be evidenced by a participation agreement in form
acceptable to such Bank. Each such participation agreement shall provide that such Bank shall
retain the sole right to exercise its rights under this Agreement and to enforce the obligations
owed to it hereunder pursuant to its Participation including, without

 

39

 

limitation, the right to consent to any modification, amendment or waiver of any provision of
this Agreement or the Letter of Credit or any assignment of the Company’s obligations under any of
the Transaction Documents or the Financing Documents; provided that any such participation
agreement may provide that such Bank will not, without the consent of the Participant, consent to
any modification, amendment or waiver of this Agreement or the Letter of Credit that (w) increases
the Maximum Credit Amount or Maximum Drawing Amount or subjects such Bank to any additional
obligation under this Agreement or the Letter of Credit, (x) reduces the principal of or rate of
interest on any reimbursement obligation or reduces the letter of credit commission payable under
Section 2(b), (y) postpones the date fixed for any payment of principal of or interest on any
reimbursement obligation or any payment of such letter of credit commission or (z) extends the
Stated Termination Date or the Termination Date, in each case subject to such participation.

(ii) Subject to clause (iii) below, the Company agrees that each Participant shall be
entitled to the benefits of Sections 2(d) and 2(e) to the same extent as if it were a Bank
and had acquired its interest by assignment pursuant to Section 15(a).

(iii) A Participant shall not be entitled to receive any greater payment under Section
2(d) or 2(e) than the applicable Bank would have been entitled to receive with respect to
the participating interest granted to such Participant, unless the granting of such interest
to such Participant is made with the Company’s prior written consent. A Participant
organized under the laws of a jurisdiction outside the United States shall not be entitled
to the benefits of Section 2(d) or 2(e) unless the Company is notified of the participating
interest granted to such Participant and such Participant agrees, for the benefit of the
Company, to comply with Section 2(d) or 2(e) as though it were a Bank.

Section 16. Continuing Obligation; Binding Effect. The obligations of the Company under this Agreement
shall continue until the later of (i) the Termination Date and (ii) the date upon which all amounts
due and owing to the Administrative Agent or any Bank hereunder shall have been paid in full. The
obligation of the Company to reimburse the Administrative Agent, the Issuing Bank and the Banks
pursuant to Sections 2(d), 2(e), 19 and 21 hereof and the obligations of the parties pursuant to
Sections 22, 24 and 27 hereof shall survive the termination of the Letter of Credit and this
Agreement. This Agreement shall be binding upon and inure to the benefit of each of the parties
hereto and their respective successors. The Company shall not have the right to assign its rights
hereunder or any interest herein to any Person without the prior written consent of the Issuing
Bank and each Bank. The Issuing Bank shall not have the right to assign its rights as the Issuing
Bank hereunder without the prior written consent of the Company (which shall not be unreasonably
withheld) and each Bank.

Section 17. Extension of the Letter of Credit. At least 105 days but not more than 180 days before the
Stated Termination Date, the Company may request the Administrative Agent in writing (each such
request being irrevocable and binding), with a copy to the Issuing Bank and each Bank, to extend
for not less than three years, nor more than eight years (or, if earlier, the end of the Basic
Lease Term or as otherwise required under the Participation Agreement), the Stated Termination
Date, specifying the terms and conditions, including fees, to be applicable to such extension.
Within 45 days after receiving such extension request (or such later date as the Company may
authorize in writing, but in no event later than 60 days before the Stated

 

40

 

Termination Date), each Bank shall notify the Administrative Agent and the Company of its
consent or nonconsent to such extension request, and if any Bank shall give no such notice, it
shall be deemed not to have consented to such extension request. No such requested extension shall
be effective without the consent of all the Banks. The consent of any Bank shall be in its sole
discretion and shall be conditional upon no Reimbursement Default or Reimbursement Event of Default
existing as of the date of such extension and the preparation, execution and delivery of legal
documentation in form and substance satisfactory to such Bank and its counsel, incorporating
substantially the terms and conditions contained in the extension request as the same may be
modified by agreement among the Company, and the Banks, and evidence satisfactory to it of the due
authorization and validity thereof.

Section 18. Limited Liability of the Banks.

(a) The Company assumes all risks of the acts or omissions of the Equity Participant and any
beneficiary or transferee of the Letter of Credit with respect to its use of the Letter of Credit.
None of the Administrative Agent, the Issuing Bank and the Banks, nor their respective Affiliates
nor any officer, director, employee or agent of any of the foregoing shall be liable or responsible
for: (a) the use which may be made of the Letter of Credit or any acts or omissions of the Equity
Participant or any beneficiary or transferee in connection therewith; (b) the validity, sufficiency
or genuineness of documents, or of any endorsement thereon, even if such documents shall prove to
be in any or all respects invalid, insufficient, fraudulent or forged; (c) payment by the Issuing
Bank against presentation of documents which do not comply with the terms of the Letter of Credit,
including failure of any documents to bear any reference or adequate reference to the Letter of
Credit; or (d) any other circumstances whatsoever in making or failing to make payment under the
Letter of Credit, except that the Company shall have a claim against the Issuing Bank, and the
Issuing Bank shall be liable to the Company, to the extent, but only to the extent, of any direct,
as opposed to special, indirect, consequential or punitive, damages or losses suffered by the
Company which the Company proves were caused by the Issuing Bank’s gross negligence or willful
misconduct in (i) honoring a presentation that does not strictly comply with the Letter of Credit,
(ii) failing to honor a presentation that strictly complies with the Letter of Credit or (iii)
retaining any document presented for purposes of drawing under the Letter of Credit. In no event
shall the Issuing Bank be deemed to have failed to act with due diligence or reasonable care if the
Issuing Bank’s conduct is in accordance with Standard Letter of Credit Practice and in accordance
with this Agreement. In furtherance and not in limitation of the foregoing, the Issuing Bank may
accept documents that appear on their face to be in order, without responsibility for further
investigation, regardless of any notice or information to the contrary unless the Equity
Participant and the Company have notified the Issuing Bank in writing prior to a drawing under the
Letter of Credit that such documents do not comply with the Letter of Credit.

(b) Without limiting any other provision of this Agreement, the Issuing Bank and each other
Indemnified Party (if applicable), shall not be responsible to the Company for, and the Issuing
Bank’s rights and remedies against the Company and the Company’s obligation to reimburse the
Issuing Bank shall not be impaired by: (i) honor of a presentation under the Letter of Credit which
on its face strictly complies with the terms of the Letter of Credit; (ii) honor of a presentation
of any documents presented for purposes of drawing under the Letter of Credit (a “Drawing
Document”) which appear on their face to have been signed, presented or issued (X)

 

41

 

by any purported successor or transferee of any beneficiary or other party required to sign,
present or issue the Drawing Documents or (Y) under a new name of the beneficiary; (iii) acting
upon any communication or instruction (whether oral, telephonic, written, telegraphic, facsimile or
electronic) (each an “Instruction”) that is unauthorized and that is (x) received pursuant to the
express terms of the Letter of Credit or (y) any other Instruction regarding the Letter of Credit
or error in computer transmission that in either case the Indemnified Party, in Good Faith,
believes to have been given by a Person or entity authorized to give such Instruction; (iv) any
errors, omissions, interruptions or delays in transmission or delivery of any message, advice or
document (regardless of how sent or transmitted) or for reasonable errors in interpretation of
technical terms made in good faith after advice of counsel or in translation; (v) any delay in
giving or failing to give any notice; (vi) any acts, omissions or fraud by, or the solvency of, any
beneficiary, any nominated Person or any other Person other than the Issuing Bank or an Indemnified
Party; (vii) any breach of contract between the beneficiary and the Company or any of the parties
to the underlying transaction; (viii) assertion or waiver of any provision of the ISP which
primarily benefits an issuer of a letter of credit, including, any requirement that any Drawing
Document be presented to it at a particular hour or place, except to the extent such provisions of
the ISP conflict with the express provisions of the Letter of Credit or this Agreement; (ix)
dishonor of any presentation for which the Company is unable or unwilling to reimburse or indemnify
the Issuing Bank (provided that the Company acknowledges that if the Issuing Bank shall later be
required to honor the presentation, the Company shall be liable therefor in accordance with Article
2 hereof); and (x) acting or failing to act as required or permitted under Standard Letter of
Credit Practice. For purposes of this Section 18(b), “Good Faith” means honesty in fact in the
conduct of the transaction concerned. For the avoidance of doubt, it is understood that this
Section 18(b) shall not be construed to limit the Issuing Bank’s liability for damages caused by
the Issuing Bank’s gross negligence or willful misconduct as otherwise provided for in this
Agreement.

(c) The Company shall notify the Administrative Agent and the Issuing Bank of (i) any
noncompliance with any Instruction given by the Company with respect to the Letter of Credit or any
amendment thereto, any other irregularity with respect to the text of the Letter of Credit or any
amendment thereto or any claim of an unauthorized, fraudulent or otherwise improper Instruction
given by the Company with respect to the Letter of Credit or any amendment thereto, in each case
within ten (10) Business Days after an Authorized Officer of the Company becomes aware of the
receipt by the Company of a copy of the Letter of Credit or any such amendment and (ii) any
objection the Company may have to the Issuing Bank’s honor or dishonor of any presentation under
the Letter of Credit or any other action or inaction taken or proposed to be taken by the Issuing
Bank under or in connection with this Agreement or the Letter of Credit, within ten (10) Business
Days after an Authorized Officer of the Company becomes aware of the objectionable action or
inaction. To the extent allowed by applicable law, the failure to so notify the Issuing Bank
within said times shall discharge the Issuing Bank from any loss or liability that the Issuing Bank
could have avoided or mitigated had it received such notice, to the extent that the Issuing Bank
could be held liable for damages hereunder; provided that the foregoing shall not be construed to
excuse the Issuing Bank from liability to the Company to the extent of any direct damages (as
opposed to consequential damages, claims in respect of which are hereby waived by the Company to
the extent permitted by applicable law) suffered by the Company that are caused by the Issuing
Bank’s failure to exercise care when determining whether drafts and other documents presented under
the Letter of Credit comply

 

42

 

with the terms thereof or by the Issuing Bank’s gross negligence or willful misconduct;
provided, further, that, if the Company shall not provide such notice to the Issuing Bank within
twenty (20) Business Days of the date of receipt, the Issuing Bank shall have no liability
whatsoever for such noncompliance, irregularity, action or inaction and the Company shall be
precluded from raising such noncompliance, irregularity or objection as a defense or claim against
Issuing Bank. For the avoidance of doubt, it is understood that this Section 18(c) shall not be
construed to limit the Issuing Bank’s liability for damages caused by the Issuing Bank’s gross
negligence or willful misconduct as otherwise provided for in this Agreement.

Section 19. Cost, Expenses and Taxes. The Company agrees to pay not later than 30 days after demand
therefor (a) all reasonable costs and expenses of the Administrative Agent in connection with the
preparation, execution, delivery, filing, recording and administration of this Agreement and any
other documents which may be delivered in connection with this Agreement and any waiver or consent
under, or amendment of, this Agreement, the Fee Letter or any of the Transaction Documents or
Financing Documents, including, without limitation, the reasonable fees and out-of-pocket expenses
of one firm of attorneys for the Administrative Agent (and any additional firms required to address
matters in respect of which such firm is precluded from representation as a result of conflicts)
and local counsel who may be retained by said counsel, with respect thereto and with respect to
advising the Administrative Agent as to its rights and responsibilities under this Agreement; (b)
as to the Administrative Agent, the Issuing Bank and each Bank, all reasonable costs and expenses
(including reasonable counsel fees and expenses) in connection with (i) the enforcement of this
Agreement and such other documents which may be delivered in connection with this Agreement or (ii)
any action or proceeding relating to a court order, injunction or other process or decree
restraining or seeking to restrain the Issuing Bank from paying any amount under the Letter of
Credit; and (c) as to the Administrative Agent and the Issuing Bank, all reasonable costs and
expenses (including reasonable counsel fees and expenses) in connection with each transfer of the
Letter of Credit in accordance with its terms. In addition, the Company shall pay any and all
stamp, documentary, filing, recording or other similar taxes and fees payable or determined to be
payable in connection with the execution, delivery, filing and recording of this Agreement and such
other documents, and agrees to save the Administrative Agent and each Bank harmless from and
against any and all liabilities with respect to or resulting from any delay in paying or omission
to pay such taxes and fees, provided that the Administrative Agent and each Bank agree promptly to
notify the Company of any such taxes and fees which are incurred by the Administrative Agent or
such Bank. To the extent permitted by applicable law, the foregoing provisions shall supersede any
costs and expenses provisions set forth in Section 8.02 of the ISP.

Section 20. Administrative Agent; Issuing Bank. (a)

(i) Each Bank irrevocably appoints and authorizes the Administrative Agent to take such action
as agent on its behalf and to exercise such powers under this Agreement as are delegated to the
Administrative Agent by the terms hereof, together with all such powers as are reasonably
incidental thereto.

(ii) The Administrative Agent shall not have any duties or obligations except those expressly
set forth herein. Without limiting the generality of the foregoing, (a) the Administrative Agent
shall not be subject to any fiduciary or other implied duties, regardless of

 

43

 

whether a Reimbursement Event of Default has occurred and is continuing, (b) the
Administrative Agent shall not have any duty to take any discretionary action or exercise any
discretionary powers, except discretionary rights and powers expressly contemplated herein that the
Administrative Agent is required to exercise in writing as directed by the Required Banks (or such
other number or percentage of the Banks as shall be necessary under the circumstances as provided
in Section 10), and (c) except as expressly set forth herein, the Administrative Agent shall not
have any duty to disclose, and shall not be liable for the failure to disclose, any information
relating to the Company or any of its Subsidiaries that is communicated to or obtained by the bank
serving as Administrative Agent or any of its Affiliates in any capacity. The Administrative Agent
shall not be liable for any action taken or not taken by it with the consent or at the request of
the Required Banks (or such other number or percentage of the Banks as shall be necessary under the
circumstances as provided in Section 10), or in the absence of its own gross negligence or willful
misconduct. The Administrative Agent shall be deemed not to have knowledge of any Reimbursement
Event of Default unless and until written notice thereof is given to the Administrative Agent by
the Company or a Bank, and the Administrative Agent shall not be responsible for or have any duty
to ascertain or inquire into (i) any statement, warranty or representation made in or in connection
with this Agreement, (ii) the contents of any certificate, report or other document delivered
hereunder or in connection with this Agreement, (iii) the performance or observance of any of the
covenants, agreements or other terms or conditions set forth in this Agreement, (iv) the validity,
enforceability, effectiveness or genuineness of this Agreement or any other agreement, instrument
or document, or (v) the satisfaction of any condition set forth in Section 3 or elsewhere in this
Agreement, other than to confirm receipt of items expressly required to be delivered to the
Administrative Agent.

(iii) The Administrative Agent shall be entitled to rely upon, and shall not incur any
liability for relying upon, any notice, request, certificate, consent, statement, instrument,
document or other writing reasonably believed by it to be genuine and correct and to have been
signed or sent by the proper Person. The Administrative Agent also may rely upon any statement
made to it orally or by telephone (except when a writing is expressly required) and reasonably
believed by it to be made by the proper Person, and shall not incur any liability for relying
thereon.

(iv) The Administrative Agent may perform any and all its duties and exercise its rights and
powers hereunder by or through any one or more sub-agents appointed by the Administrative Agent in
the exercise of reasonable care.

(v) Subject to the appointment and acceptance of a successor Administrative Agent as provided
in this paragraph, the Administrative Agent may resign at any time by notifying the Banks and the
Company. Upon any such resignation, the Required Banks shall have the right, with the prior
written approval of the Company (which approval will not be unreasonably withheld or delayed and
which shall be required only so long as no Reimbursement Event of Default shall be continuing), to
appoint a successor. If no successor shall have been so appointed by the Required Banks and shall
have accepted such appointment within 30 days after the retiring Administrative Agent gives notice
of its resignation, then the retiring Administrative Agent may, on behalf of the Banks, appoint a
successor Administrative Agent which shall be a commercial bank having capital and retained
earnings of at least $100,000,000 or an Affiliate of any such commercial bank. Upon the acceptance
of its appointment as Administrative Agent

 

44

 

hereunder by a successor, such successor shall succeed to and become vested with all the
rights, powers, privileges and duties of the retiring Administrative Agent, and the retiring
Administrative Agent shall be discharged from its duties and obligations hereunder. The fees
payable by the Company to a successor Administrative Agent shall be the same as those payable to
its predecessor unless otherwise agreed between the Company and such successor. After the
Administrative Agent’s resignation hereunder, the provisions of this Section 20 and Sections 19 and
21 shall continue in effect for the benefit of such retiring Administrative Agent, its sub agents
and their respective Affiliates in respect of any actions taken or omitted to be taken by any of
them while it was acting as Administrative Agent.

(vi) Each Bank acknowledges that it has, independently and without reliance upon the
Administrative Agent or any other Bank 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 Bank
also acknowledges that it will, independently and without reliance upon the Administrative Agent or
any other Bank 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 or related agreement or any document furnished hereunder.

(b) The Administrative Agent and its Affiliates may accept deposits from, make loans or
otherwise extend credit to, and generally engage in any kind of business with, the Company, the
Equity Participant and their respective Subsidiaries and Affiliates and receive payment on such
loans or extensions of credit and otherwise act with respect thereto freely and without
accountability in the same manner as if this Agreement and the transactions contemplated hereby
were not in effect.

(c) The Administrative Agent may consult with legal counsel (who may be counsel for the
Company), independent public accountants and other experts as it may select and shall not be liable
for any action taken or omitted to be taken by it in good faith in accordance with the advice of
such counsel, accountants or experts.

(d) It is understood that the Issuing Bank will exercise and give the same care and attention
to the Letter of Credit as it gives to its other letters of credit and loans for its own account
and that the Issuing Bank shall have no obligation to the Company or any other Bank and no duty or
responsibility with respect to this Agreement or the Letter of Credit, except as expressly provided
herein and in the Letter of Credit. Without limiting the generality of the foregoing, the Issuing
Bank shall not be required to take any action with respect to any Reimbursement Default, except as
expressly provided in Section 9 hereof. The Issuing Bank shall not be liable for any action taken
or not taken at the request or with the approval of the Required Banks (or all the Banks, as
applicable) or for the performance or non-performance of the obligations of any other party under
this Agreement or any Transaction Document or Financing Document or any other document contemplated
thereby. It is further understood that: (i) except as expressly limited by the provisions of this
Agreement, the Issuing Bank retains the sole right to exercise its rights and enforce the
obligations of the Company under this Agreement, and the Issuing Bank may use its sole discretion
with respect to exercising or refraining from exercising any rights or taking or refraining from
taking any actions which may be vested in it or which it may be entitled to take or assert under
this Agreement or any of the Transaction

 

45

 

Documents or Financing Documents (including, without limitation, the giving of any notice to
any Person of any Reimbursement Event of Default under this Agreement except as provided in Section
9); and (ii) the Issuing Bank shall not, in the absence of gross negligence or willful misconduct,
be under any liability to any other Bank with respect to anything which the Issuing Bank may do or
refrain from doing in the exercise of its best judgment or which it may deem to be necessary or
desirable. Neither the Administrative Agent nor the Issuing Bank shall incur any liability by
acting in reliance upon any written communication or any telephone conversation which it reasonably
believes to be genuine and correct or to have been signed, sent or made by the proper Person.
Neither the Administrative Agent nor the Issuing Bank shall have any obligation to make any claim
on, or assert any lien upon, or assert any setoff against, any property held by it and, if it
elects to do so, it may in its discretion apply the same against indebtedness of the Company other
than the Company’s obligations under this Agreement; provided that, to the extent any funds
received pursuant to any of the foregoing are applied to the obligations of the Company under
Section 2(a) or 2(b) hereof, each Bank shall be entitled to receive its pro rata share thereof in
accordance with Section 14(b) above. Any such setoff or other action in respect of any
reimbursement obligation of the Company set forth in Section 2(a) will be subject to Section 13.

Section 21. Indemnification. (a) To the fullest extent permitted by law, the Company shall indemnify and
hold harmless the Administrative Agent, the Issuing Bank, each Bank, their respective affiliates
and correspondents and each of their respective directors, officers, employees and agents (each
such party, an “Indemnified Party”) from and against any and all claims, suits, judgments, costs,
losses, fines, penalties, damages, liabilities, and expenses, including expert witness fees and
reasonable legal fees, charges and disbursements of any counsel (including in-house counsel fees
and allocated costs) for any Indemnified Party (“Costs”) (except to the extent any such Costs are
expressly stated in this Agreement to be payable by the Indemnified Party or to the extent
expressly limited pursuant to Sections 2(d), 2(e), 2(f), 7(e), 18(a) and 19), arising out of, in
connection with, or as a result of: (i) the Letter of Credit or any pre-advice of its issuance;
(ii) any action or proceeding arising out of or in connection with the Letter of Credit or this
Agreement (whether administrative, judicial or in connection with arbitration), including any
action or proceeding to compel or restrain any presentation or payment under the Letter of Credit,
or for the wrongful dishonor of or honoring a presentation under the Letter of Credit; (iii) any
Instruction that is unauthorized and that is (x) received pursuant to the express terms of the
Letter of Credit or (y) any other Instruction regarding the Letter of Credit or error in computer
transmission that in either case the Indemnified Party reasonably believed to be authorized; (iv)
any third party seeking to enforce the rights of an applicant, beneficiary, nominated person,
transferee or assignee of proceeds of the Letter of Credit; (v) the fraud, forgery or illegal
action of parties other than the Indemnified Party (including, for the avoidance of doubt, any
fraud, forgery or illegal action by any party in connection with any transfer of the Letter of
Credit); (vi) the enforcement against the Company of this Agreement or any rights or remedies under
or in connection with this Agreement or the Letter of Credit; (vii) the Administrative Agent’s or
the Issuing Bank honoring any presentation upon or during the continuance of any Reimbursement
Event of Default or for which the Company is unable or unwilling to make any payment to the
Administrative Agent, the Issuing Bank or any Bank as required under this Agreement; (viii) the
acts or omissions, whether rightful or wrongful, of any present or future de jure or de facto
governmental or regulatory authority or cause or event beyond the control of such Indemnified
Party; in each case, including that

 

46

 

resulting from the Administrative Agent’s or the Issuing Bank’s own negligence, provided,
however, that such indemnity shall not be available to any Person claiming indemnification under
(i) through (viii) above to the extent that such Costs are found in a final, non-appealable
judgment by a court of competent jurisdiction to have resulted directly from the gross negligence
or willful misconduct of the Indemnified Party claiming indemnity, in which case any fees or
expenses previously paid or advanced by the Company to such Indemnified Party in respect of such
indemnified obligation (if any) will be returned by such Indemnified Party. Without limitation of
the foregoing, the Company shall not be required to indemnify the Issuing Bank or its Related
Parties pursuant to this Section for any Costs to the extent solely caused by (i) the Issuing
Bank’s willful misconduct or gross negligence in determining whether documents presented under the
Letter of Credit comply with the terms of the Letter of Credit or (ii) its willful failure to make
lawful payment under the Letter of Credit after presentation to it by the beneficiary of the Letter
of Credit of documents strictly complying with the terms and conditions of the Letter of Credit.
If and to the extent that the obligations of Company under this paragraph are unenforceable for any
reason, Company shall make the maximum contribution to the Costs permissible under applicable law.

(b) To the extent permitted by applicable law, the foregoing provisions shall supersede any
indemnity provisions set forth in Section 8.01(b) of the ISP.

(c) To the extent that the Administrative Agent or the Issuing Bank is not reimbursed and
indemnified by the Company under this Agreement, each Bank will reimburse and indemnify the
Administrative Agent and the Issuing Bank on demand for and against such Bank’s Participation
Percentage of any and all claims, demands, liabilities, obligations, losses, damages, penalties,
actions, judgments, suits, costs, expenses or disbursements (including fees and disbursements of
counsel) of any kind or nature whatsoever which may be imposed on, incurred by, or asserted against
the Administrative Agent or the Issuing Bank in any way relating to or arising out of this
Agreement, the Fee Letter, the Letter of Credit, or any of the Transaction Documents or Financing
Documents or any action taken or omitted to be taken by the Administrative Agent or the Issuing
Bank hereunder or thereunder, or the transactions contemplated hereby and thereby or the
enforcement of any of the terms hereof and thereof; provided that such Bank shall not be liable for
any portion of such claims, demands, liabilities, obligations, losses, damages, penalties, actions,
judgments, suits, costs, out-of-pocket expenses or disbursements resulting from the gross
negligence or willful misconduct of the Administrative Agent or the Issuing Bank or which are
expressly excluded from the indemnification by the Company by the proviso to the first sentence of
Section 21(a), or by the second sentence of Section 21(a) of this Agreement. Each Bank’s
obligations under this Section 21(c) shall survive the termination of this Agreement and the Letter
of Credit. If the Administrative Agent or the Issuing Bank is reimbursed by the Company for any
amounts previously received from any Bank pursuant to this Section 21(c), it will promptly pay to
such Bank its proportionate share of any amounts so received.

Section 22. Confidentiality. (a) The Administrative Agent and each Bank agree (on behalf of themselves
and each of their Affiliates, directors, officers, employees and representatives) to take normal
and reasonable precautions and exercise due care to maintain the confidentiality of all non-public
information provided to them by the Company or any Subsidiary of the Company in connection with
this Agreement and neither the Administrative Agent, any

 

47

 

Bank nor any of their Affiliates, directors, officers, employees and representatives shall use
any such information for any purpose or in any manner other than pursuant to the terms contemplated
by this Agreement, except to the extent such information (a) was or becomes generally available to
the public other than as a result of a disclosure by the Administrative Agent or any Bank, or (b)
was or becomes available on a non-confidential basis from a source other than the Company, provided
that such source is not bound by a confidentiality agreement with the Company known to the
Administrative Agent or affected Bank after reasonable inquiry; provided that nothing herein shall
limit the disclosure of any such information (i) to the extent required by statute, rule,
regulation or judicial process; (ii) to counsel for the Administrative Agent or any Bank; (iii) to
bank examiners, auditors or accountants, on a confidential basis; (iv) to the Administrative Agent
or any other Bank; (v) by the Administrative Agent or any Bank to an Affiliate thereof who is bound
by this Section 22; provided that any such information delivered to an Affiliate shall be for the
purposes related to the extension of credit represented by this Agreement and the administration
and enforcement thereof and for no other purpose; (vi) in connection with any litigation relating
to enforcement of this Agreement or (vii) to any assignee or participant (or prospective assignee
or participant) so long as such assignee or participant (or prospective assignee or participant)
first enters into a confidentiality agreement with the respective Bank, which confidentiality
agreement shall contain terms substantially similar to the terms set forth in this Section 22.
Each Bank and the Administrative Agent agree, unless specifically prohibited by applicable law or
court order, to notify the Company of any request for disclosure of any such non-public information
(x) by any governmental authority or representative thereof (other than any such request in
connection with an examination of the financial condition of the Company by such governmental
authority) or (y) pursuant to legal process. The obligations under this Section 22 shall survive
for two (2) years after termination of this Agreement.

(b) This Agreement is intended to provide express authorization to each of the Banks and their
Affiliates (and each employee, representative, or other agent of each Bank and its respective
Affiliates) to disclose to any and all Persons, without limitation of any kind, the “tax treatment”
and “tax structure” (in each case, within the meaning of Treasury Regulation Section 1.6011-4) of
the transactions contemplated hereby and all materials of any kind (including opinions or other tax
analyses) that are provided to the Banks or any of their Affiliates (and any such employees,
representatives or other agents) relating to such tax treatment and structure; provided, that, with
respect to any document or similar item that in either case contains information concerning the tax
treatment or tax structure of the transactions contemplated hereby as well as other information,
this authorization shall only apply to such portions of the documents or similar item that relate
to the tax treatment or tax structure of the transactions contemplated hereby.

Section 23. Severability. Any provision of this Agreement which is prohibited, unenforceable or not
authorized in any jurisdiction shall, as to such jurisdiction, be ineffective to the extent of such
prohibition, unenforceability or non-authorization without invalidating the remaining provisions
hereof or affecting the validity, enforceability or legality of such provision in any other
jurisdiction.

Section 24. Governing Law; Consent to Jurisdiction. (a) This Agreement shall be governed by, and
construed in accordance with, the laws of the State of New York.

 

48

 

(b) Each party hereto submits to the nonexclusive jurisdiction of the Supreme Court of the
State of New York sitting in New York County and of the United States District Court of the
Southern District of New York, and any appellate court from any thereof, in any action or
proceeding arising out of or relating to this Agreement or for recognition or enforcement of any
judgment, and each party hereto hereby agrees, to the fullest extent permitted by law, that all
claims in respect of any such action or proceeding may be heard and determined in such New York
State or, to the extent permitted by law, in such Federal court. Nothing in this Agreement shall
affect any right that any party hereto may otherwise have to bring action or proceeding relating to
this Agreement in the courts of any jurisdiction.

Section 25. Headings. Section headings in this Agreement are included herein for convenience of reference
only and shall not constitute a part of this Agreement for any other purpose.

Section 26. Counterparts; Integration. This Agreement may be signed in any number of counterparts, each
of which shall be an original, with the same effect as if the signatures thereto and hereto were
upon the same instrument. This Agreement, the Fee Letter, that certain Commitment Agreement dated
as of March 17, 2010 between JPMorgan, J.P. Morgan Securities Inc., Union Bank, N.A., and the
Company, that certain Letter Agreement between the Issuing Bank and the Company dated as of April
16, 2010 constitute the entire agreement and understanding among the parties hereto and, subject to
Section 3(c), supersede any and all prior agreements and understandings, oral or written, relating
to the subject matter hereof.

Section 27. WAIVER OF JURY TRIAL. TO THE EXTENT ALLOWED BY LAW, EACH OF THE COMPANY, THE BANKS AND THE
ADMINISTRATIVE AGENT HEREBY IRREVOCABLY WAIVES ANY AND ALL RIGHT TO TRIAL BY JURY IN ANY LEGAL
PROCEEDING ARISING OUT OF OR RELATING TO THIS AGREEMENT OR THE TRANSACTIONS CONTEMPLATED HEREBY.

Section 28. No Advisory or Fiduciary Responsibility. In connection with all aspects of each
transaction contemplated hereby (including in connection with any amendment, waiver or other
modification hereof or any syndication of the credit facility provided hereunder), the Company
acknowledges and agrees that: (i) (A) the arranging and other services regarding this Agreement
provided by the Administrative Agent are arm’s-length commercial transactions between the Company
and its Affiliates, on the one hand, and the Administrative Agent and its Affiliates, on the other
hand, (B) it has consulted its own legal, accounting, regulatory and tax advisors to the extent it
has deemed appropriate, and (C) it is capable of evaluating, and understands and accepts, the
terms, risks and conditions of the transactions contemplated hereby; (ii) (A) the Administrative

or any other Person and (B) none of the Administrative Agent or the Company has any obligation to
each other or to their respective Affiliates with respect to the transactions contemplated hereby
except those obligations expressly set forth herein; and (iii) the Administrative Agent and its
Affiliates may be engaged in a broad range of transactions that involve interests that differ from
those of the Company and its Affiliates, and the Administrative Agent has no obligation to disclose
any of such interests to the Company or its Affiliates. To the

 

49

 

fullest extent permitted by law, the Administrative Agent and the Company hereby waive and
release any claims that they may have against each other with respect to any breach or alleged
breach of agency or fiduciary duty in connection with any aspect of any transaction contemplated
hereby. Each of the Administrative Agent and the Banks acknowledge and agree that it has consulted
its own legal, accounting, regulatory and tax advisors to the extent it has deemed appropriate.

Section 29. Waiver of Damages. To the extent allowed by law, no party hereto shall have any
liability with respect to, and each party hereto hereby waives, releases and agrees not to sue for,
any special, indirect, consequential or punitive damages or losses suffered by such party in
connection with, arising out of, or in any way related to this Agreement, the Letter of Credit or
the transactions contemplated hereby or thereby regardless of whether such party shall have been
advised of the possibility of such damages or losses or of the form of action in which such damages
or losses may be claimed.

Section 30. Government Regulations. The Company agrees to provide documentary and other
evidence of the Company’s identity as may be requested by any Bank at any time to enable such Bank
to verify the Company’s identity or to comply with any applicable law or regulation, including,

disregarded. The rating in effect at any date is that in effect at the close of business on such
date. In the case of split ratings from S&P or Moody’s, the rating to be used to determine which
pricing level applies is the higher of the two (e.g., BBB+/Baa2 results in Level II Status);
provided that if the split is more than one full rating category, the rating category next below
that of the higher of the two rating categories will be used (e.g., BBB+/Baa3 results in Level III
Status, and A-/Baa3 results in Level II Status). If the rating system of Moody’s or S&P shall
change, or if either such Rating Agency shall cease to be in the business of rating corporate debt
obligations, the Company, the Administrative Agent and the Banks shall negotiate in good faith to
amend this definition to reflect such changed rating system or the unavailability of ratings from
such Rating Agency and, pending the effectiveness of any such amendment, the Letter of Credit
Commission Rate and the Base Rate Margin shall be determined by reference to the Rating most
recently in effect prior to such change or cessation.

“S&P” means Standard & Poor’s Financial Services LLC, a division of The McGraw-Hill Companies,
Inc., and any successor thereto.

“Status” refers to the determination of which of Level I Status, Level II Status, Level III
Status, Level IV Status or Level V Status exists at any date.

Attention: President

Dear Sirs:

We hereby establish, at the request of Arizona Public Service Company (the “Company”), in your
favor, our Irrevocable Transferable Letter of Credit No. P-010152 (formerly numbered as S-1002)
(the “Letter of Credit”), in a maximum amount at any date (the “Maximum Credit Amount”) equal to
the amount shown opposite the period including such date in the Table of Maximum Credit Amounts
attached hereto as Schedule II-A, effective immediately and expiring at 5:00 p.m. (New York
City time) on the Termination Date. Capitalized terms used herein and in Schedules II-A,
II-B and III and Exhibits 1, 2, 3 and 4
hereto shall have the meanings set forth in Schedule I hereto. This Letter of Credit is
issued in connection with the leasing of an undivided interest in Unit 2 of the Palo Verde Nuclear
Generating Station to the Company pursuant to a Facility Lease dated as of August 1, 1986 (the
“Facility Lease”) as amended and in effect on the date hereof, between the Company and U.S. Bank
National Association (as successor to State Street Bank and Trust Company, as successor to The
First National Bank of Boston), as Owner Trustee under a trust agreement with you.

We hereby irrevocably authorize you to draw on us, in accordance with the terms and conditions
hereinafter set forth, an amount not in excess of the amount shown opposite the period including
the date of such drawing (the “Date of Drawing”) in the Table of Maximum Drawing Amounts attached
hereto as Schedule II-B as such amounts are modified from time to time in accordance with
the next paragraph. Such amounts, as modified in accordance with the next paragraph, are
hereinafter referred to collectively as the “Maximum Drawing Amounts” and individually as the
“Maximum Drawing Amount”. A drawing in respect of a payment hereunder honored by us shall not
exceed the lesser of the Maximum Drawing Amount applicable on the Date of Drawing and the Maximum
Credit Amount applicable on the Date of Drawing. All payments hereunder shall be made from our own
general funds.

Exhibit A — Page 1

 

 

 

The Maximum Drawing Amounts shall be modified from time to time as follows:

(a) upon payment by the Issuing Bank of each drawing under the Letter of Credit, the Maximum
Drawing Amounts applicable to each Date of Drawing subsequent to such payment shall be
automatically reduced by an amount equal to the amount of the drawing so paid and shall not be
reinstated; and

(b) if adjustments are made to Modified Special Casualty Values, corresponding adjustments
shall be made to the Maximum Drawing Amounts shown in Schedule II-B, (as theretofore
reduced pursuant to clause (a) above), provided that if any such adjustment of Modified Special
Casualty Values would cause the Maximum Drawing Amount for any period to exceed the Maximum Credit
Amount for such period, (minus, the amount of any drawing theretofore honored by us hereunder),
such Maximum Credit Amount (as so reduced) shall apply for such period and provided further that
adjustments pursuant to this clause (b) shall be effective automatically upon receipt by us of a
notice from you in the form of Exhibit 1 hereto.

Upon receipt of a notice in the form of Exhibit 1 hereto, we will promptly issue an
amendment to this irrevocable transferable letter of credit containing a revised Schedule
II-B reflecting the adjustments contained in such notice.

Funds under this Letter of Credit are available to you against presentation on or prior to the
Termination Date of your drawing in the form of a completed certificate signed by you in the form
of Exhibit 2 attached hereto. Such certificate shall be dated the date of its presentation
and shall be presented (x) by facsimile (at facsimile number (312) 233-2266 or alternately to (312)
954-2458), Attention: Manager, without further need of documentation, including the original of
this Letter of Credit, or (y) at our Chicago office specified below, in each case, it being
understood that each certificate so submitted is to be the sole operative instrument of drawing.
You shall use your best efforts to give telephonic notice of a drawing to the Issuing Bank at its
Standby Service Unit, (at: (312) 954-5973 or alternately to 1-800-634-1969, Option 1) on the day of
such drawing (but such notice shall not be a condition to drawing hereunder and you shall have no
liability for not doing so). If we receive such certificate as provided herein, in strict
conformity with the terms and conditions of this Letter of Credit, prior to 10:00 a.m. (New York
City time) on any Business Day, (notwithstanding any provision of Rule 5.01 of the International
Standby Practices, ICC Publication No. 590 (the “ISP98”) to the contrary, which provisions of the
ISP98 are hereby expressly waived), we will honor the drawing on the same Business Day. If we
receive such certificate as provided herein on or after 10:00 a.m. and prior to 5:00 p.m. (New York
City time) on any Business Day, all in strict conformity with the terms and conditions of this
Letter of Credit, we will honor the drawing on the next Business Day. Payment under this Letter of
Credit will be made by wire transfer of federal funds to your account with any bank located in the
United States of America or by deposit of immediately available funds into a designated account
that you maintain with us.

Notwithstanding any provision of Section 5-108(b) of the New York Uniform Commercial Code (the
“NY UCC”) or Rule 5.01 of the ISP98 to the contrary, which provisions are hereby expressly waived,
if the presentation of such certificate is not in strict conformity with the terms and conditions
of this Letter of Credit, we will give you prompt notice prior to the time we would have been
obliged to make payment as set forth in the preceding paragraph by

Exhibit A — Page 2

 

 

 

facsimile transmission addressed to you at the fax number set forth in the next succeeding
paragraph, effective upon confirmation, that we have refused such non-conforming certificate, and
stating all discrepancies in respect of which the Issuing Bank refuses such non-conforming
certificate. If you correct such non-conforming demand by presentation of the certificate
corrected to be in strict conformity with the terms and conditions of the Letter of Credit, then we
will honor the drawing and make payment in accordance with the terms provided herein based upon the
time such corrected certificate is presented, provided that you may make only one such corrected
demand with respect to any such non-conforming demand, and provided further that any such
correction and presentation of such conforming demand is effected on or prior to the Stated
Termination Date, and provided further that for purposes of determining whether such certificate
has been timely presented, the corrected certificate shall be deemed to have been presented on the
date the non-conforming certificate was presented.

Notwithstanding any other provision of this Letter of Credit, we shall have the right, upon
the occurrence of any of the events listed in Schedule III hereto, to terminate this Letter
of Credit by delivering to you a written notice in the form of Exhibit 4 hereto indicating
the date of such termination (the “Date of Early Termination”), provided that on or before the Date
of Early Termination you will have the right to draw once an amount not in excess of the lesser of
the Maximum Credit Amount and the Maximum Drawing Amount in accordance with the procedures
described herein. The written notice referred to in the preceding sentence shall be given by
facsimile transmission addressed to you at Emerson Finance LLC, 8000 W. Florissant Avenue, P.O. Box
4100, St. Louis, Missouri 63136; Attention: President; Fax: 314-553-2463 (or to such other address
or facsimile number designated by you by written notice delivered to us at least 15 days prior to
the notice of early termination) and shall be effective upon receipt of the appropriate
confirmation of the facsimile transmission. We will also forward a copy of such notice by
overnight delivery service to the address set forth above. The Date of Early Termination specified
in such written notice shall be:

(a) in the case of events specified in paragraphs A and G of Schedule III, not earlier
than ten days after such notice is given, and

(b) in the case of all other events specified in Schedule III, not earlier than 30
days after such notice is given.

Upon the Termination Date this Letter of Credit shall automatically terminate and be delivered
to the Issuing Bank for cancellation. Failure to deliver said Letter of Credit will have no effect
on the Termination Date, and the Letter of Credit will still be considered terminated.

Notwithstanding the provisions of Section 5-112(b)(2) of the NY UCC that permit the Issuing
Bank to refuse to recognize or carry out a transfer of this Letter of Credit if the transferee has
failed to comply with any other requirement relating to transfer imposed by the Issuing Bank which
is within the standard practice referred to in Section 5-108(e) of the NY UCC or is otherwise
reasonable under the circumstances, which provisions are hereby expressly waived, this Letter of
Credit may be transferred in its entirety more than once, but in each case only to the successor
Equity Participant under the Trust Agreement dated as of August 1, 1986 between yourself and U.S.
Bank National Association (as successor to State Street Bank and Trust Company, as successor to The
First National Bank of Boston). Any transfer request must be

Exhibit A — Page 3

signed by the transferor and by the transferee accompanied by the original of this Letter of Credit
and any amendments thereto (which presentation of an appropriately completed Exhibit 3
shall be conclusive evidence of such transferee’s authority without any inquiry by us into the
terms of the Trust Agreement). Upon the Issuing Bank’s endorsement of such transfer, the
transferee instead of the transferor shall, without necessity of further action, be entitled to all
the benefits of and rights under this Letter of Credit in the transferor’s place.

Notwithstanding any provision of Rule 3.12 of the ISP98 to the contrary, which provisions are
hereby expressly waived, upon the Issuing Bank’s receipt of its standard certificate duly executed
by you certifying that the original of this Letter of Credit has been lost, destroyed or mutilated,
the Issuing Bank shall provide a true copy of original (which copy shall be marked as such) of this
Letter of Credit to you without affecting the Company’s obligations to the Issuing Bank to
reimburse. Upon delivery of such copy, any requirement that the original be presented hereunder
shall be deemed to be a reference to such copy.

Except as expressly stated herein, this Letter of Credit is governed by, and construed in
accordance with the ISP98. As to matters not governed by the ISP98, this Letter of Credit shall be
governed by and construed in accordance with the laws of the State of New York, including without
limitation the NY UCC as in effect in the State of New York, without regard to principles of
conflict of laws (other than Sections 5.1401 and 5.1402 of the General Obligations Law of the State
of New York).

referring to the number of this Letter of Credit, and addressed and presented to the Issuing Bank

any way be modified, amended, amplified or limited by reference to any document, instrument or

year anniversary date (the “Second Year Incentive”). [If, within two years following the

	 	•	 	Eligibility to participate in the Supplemental Executive Benefit Retirement Plan. The
SEBRP is structured as a cash balance plan to which the company contributes 28 percent of
your base and annual incentive compensation.

	 	•	 	Eligibility to participate in the company’s 401(k) plan. You are eligible to contribute

employment, you will become eligible for the company matching contribution of 75 cents for
every dollar you contribute, up to 6 percent of your compensation.

	 	•	 	Eligibility to participate in the Deferred Compensation Plan (DCP.) The DCP provides
you with the opportunity to defer part of your compensation on a pre-tax basis. The
deferred amount also earns interest. The company sets the interest amount each calendar
year.

compensation arrangement and provide an initial credit of $350,000. The first $250,000
credit will vest upon the fifth anniversary of your hire date and the last $100,000 credit
will vest upon the seventh anniversary of your hire date, in each case, subject to your
continued employment through the applicable vesting date. The initial credit will earn
interest in accordance with the Pinnacle West Deferred Compensation Plan.

provide severance benefits in connection with a change of control on terms and conditions
generally applicable to other similarly situated executives of the Company, but modified to
comply with the policies set forth in the Form 8-K filed by the Company on May 4, 2009. In
the event of payment under this agreement, you would receive 2.99 times base salary and
annual incentive as described in the agreement.

	 	•	 	If you enroll in the company’s benefit program within the first 30 days of employment,
your medical, dental, and life insurance will be effective on your one-month anniversary
date of employment. Medical and dental plan premiums are on a pre-tax basis.

	 	•	 	You will be eligible for the relocation benefits provided generally to the Company’s
senior executives.

All items of compensation, and all benefits, that are provided pursuant to a compensation or
benefit plan or agreement will be subject to the terms and provisions of the relevant plan or
agreement and, in all cases, the Company reserves the right to modify, amend, suspend or terminate
the applicable plan or agreement.

In the event that, prior to the second anniversary of your hire date, your employment is terminated
by the Company without Cause and you are not entitled to severance benefits under the KEESA,
subject to your execution and non-revocation of a general release of claims against the Company and
its affiliates within 55 days after your termination, you will receive continuation of your annual
base salary at the rate in effect immediately preceding the date on which your employment
terminates for a period of twelve months commencing on the date that is 60 days following your
termination, such payments to be made in accordance with the Company’s normal payroll practices as
in effect on the date of termination. You will also be paid a target bonus. In addition, for a
period of 12 months following your termination, you will be paid a monthly amount equal to the
monthly employer-paid portion of the premiums for active senior executives’ health care coverage as
in effect from time to time during such 12-month period. Each payment under this paragraph will be
deemed a separate payment and, to the extent required to comply with Section 409A of the Code, will
be delayed until the date that is six months after your separation from service.

For purposes of this Agreement, “Cause” means (i) your engaging in conduct which has caused
demonstrable and serious injury to the Company, monetary or otherwise; (ii) commission of a felony;
(iii) your unreasonable neglect or refusal to perform your duties or responsibilities; (iv) an act
by you of gross or willful misconduct; or (v) a material breach of the Company’s policies that are
applicable to you.

Your employment is “at will” which means that either you or the Company may terminate your
employment at any time for any reason with or without notice.

You represent that you have full authority to execute this offer letter and that neither executing
this letter or providing services to the Company or its affiliates will constitute a breach of any
agreement that you may have with any other party.

This offer is contingent upon successful completion of a pre-employment medical screening and
background check.
