Summary of 2010 Incentive Plans

On December 15, 2009, the Human Resources Committee (the “Committee”) approved the Pinnacle West 2010 Annual
Incentive Award Plan (the “PNW Plan”), which provides an incentive award opportunity for Donald E. Brandt, the Chairman
of the Board and Chief Executive Officer of Pinnacle West and Arizona Public Service Company (“APS”). On December 16,
2009, the Board of Directors of Pinnacle West, acting on the recommendation of the Committee, approved the APS 2010
Annual Incentive Award Plan (the “APS Plan”) and the 2010 APS Palo Verde Employee Incentive Plan (the “Palo Verde
Plan”), which provide incentive award opportunities for Pinnacle West and APS employees, including the following “named
executive officers” from the 2009 Proxy Statement: James R. Hatfield, Senior Vice President, Chief Financial Officer
and Treasurer; Randall K. Edington, Executive Vice President and Chief Nuclear Officer of APS; and Steven M. Wheeler,
Executive Vice President, Customer Service and Regulation, of APS. The PNW Plan, the APS Plan, and the Palo Verde Plan
are referred to collectively herein as the “2010 Plans.”

No incentive payments will be awarded under the 2010 Plans unless Pinnacle West, with respect to Mr. Brandt, and
APS, with respect to Messrs. Hatfield, Wheeler and Edington, achieves a specified threshold earnings level. The
Committee may evaluate the impacts of unusual or nonrecurring adjustments to earnings in determining whether any
earnings level has been met for purposes of the 2010 Plans, and the impacts of any sale or disposal of assets will be
excluded for purposes of the PNW Plan.

The award opportunity for Mr. Brandt under the PNW Plan is based on the achievement of specified 2010 Pinnacle
West earnings levels. The award achieved may be further adjusted by the Committee based upon its evaluation of Mr.
Brandt’s individual performance. Mr. Brandt has an award opportunity of up to 50% of his base salary if the threshold
earnings level is met, up to 100% of his base salary if a target earnings level is met, and up to 150% of his base
salary if a maximum earnings level is met, before adjustment for individual performance. In considering Mr. Brandt’s
individual performance, the Committee may take into account factors such as shareholder value, financial strength,
operating performance, development and execution of corporate strategy and safety.

The award opportunities for Messrs. Hatfield and Wheeler under the APS Plan are based on the achievement of
specified 2010 APS earnings levels and specified business unit performance goals. The awards achieved may be further
adjusted by the Committee, with input from the Chief Executive Officer, based upon its evaluation of each officer’s
individual performance. Each officer has a target award opportunity of up to 50% of his base salary. He may earn less
than the target amount or more, up to a maximum award opportunity of up to 100% of his base salary, depending on the
achievement of the earnings and business unit performance goals separately or in combination, and before adjustment for
individual performance. The business unit performance measures that will be considered for Mr. Hatfield and Mr. Wheeler
are derived from APS’ five critical areas of focus as provided in its Strategic Framework: customers and communities, employees, environmental stewardship, operational excellence and shareholder
value. In considering each officer’s individual performance, with input from the Chief Executive Officer, the Committee
may take into account factors such as effective cost and financial management, APS’ financial strength, operational
performance, customer service, regulatory processes and safety.

  
The award opportunity for Mr. Edington under the Palo Verde Plan is based on the achievement of specified 2010 APS
earnings levels and specified business unit performance goals. Mr. Edington has an award opportunity of 25% of his base
salary up to 100% of his base salary depending on the achievement of the earnings and business unit performance goals
separately or in combination. The business unit performance indicators that will be considered for Mr. Edington are in
the areas of safety, employee performance, achievement of operational metrics for the Palo Verde Nuclear Generating
Station, performance improvement in key areas, and cost management.

In no event may any individual award under the PNW Plan or the APS Plan exceed 200% of the target payout level.

ARTICLE II

AMOUNTS AND TERMS OF THE ADVANCES AND LETTERS OF CREDIT

Section 2.01 The Advances and Letters of Credit.

(a) The Advances. Each Lender severally agrees, on the terms and conditions
hereinafter set forth, to make Advances in Dollars to the Borrower from time to time on any
Business Day during the period from the Effective Date until the Termination Date in an amount

 

19

 

not
to exceed such Lender’s Unused Commitment. Each Borrowing shall be in an aggregate amount of
$10,000,000 or an integral multiple of $1,000,000 in excess thereof and shall consist of Advances
of the same Type made on the same day by the Lenders ratably according to their respective
Revolving Credit Commitments. Within the limits of each Lender’s Revolving Credit Commitment, and
subject to the other terms and conditions hereof, the Borrower may borrow under this Section
2.01(a), prepay pursuant to Section 2.10 and reborrow under this Section 2.01(a).

(b) Letters of Credit. Each Issuing Bank agrees, on the terms and conditions
hereinafter set forth, in reliance upon the agreements of the other Lenders set forth in this
Agreement, to issue letters of credit (each, a “Letter of Credit”) for the account of the
Borrower from time to time on any Business Day during the period from the Effective Date until 30
days before the Termination Date in an aggregate Available Amount for all Letters of Credit issued
by each Issuing Bank not to exceed at any time such Issuing Bank’s Letter of Credit Commitment,
provided that after giving effect to the issuance of any Letter of Credit, (i) the Total
Outstandings shall not exceed the aggregate Revolving Credit Commitments and (ii) each Lender’s
Ratable Share of the Total Outstandings shall not exceed such Lender’s Revolving Credit Commitment.
No Letter of Credit shall have an expiration date (including all rights of the Borrower or the
beneficiary to require renewal) later than the Letter of Credit Expiration Date. Within the limits
referred to above, the Borrower may from time to time request the issuance of Letters of Credit
under this Section 2.01(b). The terms “issue”, “issued”, “issuance” and all similar terms, when
applied to a Letter of Credit, shall include any renewal, extension or amendment thereof.

Section 2.02 Making the Advances.

(a) Except as otherwise provided in Section 2.03(c), each Borrowing shall be made on notice,
given not later than (x) 12:00 noon on the third Business Day prior to the date of the proposed
Borrowing in the case of a Borrowing consisting of Eurodollar Rate Advances or (y) 12:00 noon on
the date of the proposed Borrowing in the case of a Borrowing consisting of Base Rate Advances, by
the Borrower to the Agent, which shall give to each Lender prompt notice thereof by facsimile.
Each such notice of a Borrowing (a “Notice of Borrowing”) shall be in writing or by
facsimile in substantially the form of Exhibit B hereto, specifying therein the requested
(i) date of such Borrowing, (ii) Type of Advances comprising such Borrowing, (iii) aggregate amount
of such Borrowing, and (iv) in the case of a Borrowing consisting of Eurodollar Rate Advances,
initial Interest Period for each such Advance. Each Lender shall, in the case of a Borrowing
consisting of Base Rate Advances, before 2:00 p.m. on the date of such Borrowing, and in the case
of a Borrowing consisting of Eurodollar Rate Advances, before 11:00 a.m. on date of such Borrowing,
make available for the account of its Applicable Lending Office
to the Agent at the Agent’s Account, in same day funds, such Lender’s Ratable Share of such
Borrowing. After the Agent’s receipt of such funds and upon fulfillment of the applicable
conditions set forth in Article III, the Agent will make such funds available to the Borrower at
the Agent’s address referred to in Section 8.02 or as requested by the Borrower in the applicable
Notice of Borrowing.

(b) Anything in subsection (a) above to the contrary notwithstanding, (i) the Borrower may not
select Eurodollar Rate Advances for any Borrowing if the aggregate amount of such Borrowing is less
than $10,000,000 or if the obligation of the Lenders to make

 

20

 

Eurodollar Rate Advances shall then be
suspended pursuant to Section 2.08 or 2.12 and (ii) at no time shall there be more than fifteen
different Interest Periods outstanding for Eurodollar Rate Advances.

(c) Each Notice of Borrowing shall be irrevocable and binding on the Borrower. In the case of
any Borrowing that the related Notice of Borrowing specifies is to be comprised of Eurodollar Rate
Advances, the Borrower shall indemnify each Lender against any loss, cost or expense reasonably
incurred by such Lender as a result of any failure to fulfill on or before the date specified in
such Notice of Borrowing for such Borrowing the applicable conditions set forth in Article III,
including, without limitation, any loss (excluding 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 Advance to be made by such Lender as part of such Borrowing when such Advance,
as a result of such failure, is not made on such date.

(d) Unless the Agent shall have received notice from a Lender prior to the time of the
applicable Borrowing that such Lender will not make available to the Agent such Lender’s Ratable
Share of such Borrowing, the Agent may assume that such Lender has made such portion available to
the Agent on the date of such Borrowing in accordance with subsection (a) of this Section 2.02 and
the Agent may, in reliance upon such assumption, make available to the Borrower on such date a
corresponding amount. If and to the extent that such Lender shall not have so made such Ratable
Share available to the Agent, such Lender and the Borrower severally agree to repay to the Agent
within one Business Day after demand for such Lender and within three Business Days after demand
for the Borrower such corresponding amount together with interest thereon, for each day from the
date such amount is made available to the Borrower until the date such amount is repaid to the
Agent, at (i) in the case of the Borrower, the interest rate applicable at the time to Advances
comprising such Borrowing and (ii) in the case of such Lender, the Federal Funds Rate. If the
Borrower and such Lender shall pay such interest to the Agent for the same or an overlapping
period, the Agent shall promptly remit to the Borrower the amount of such interest paid by the
Borrower for such period. If such Lender shall repay to the Agent such corresponding amount, such
amount so repaid shall constitute such Lender’s Advance as part of such Borrowing for purposes of
this Agreement.

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

Section 2.03 Letters of Credit.

(a) General.

(i) No Issuing Bank shall issue any Letter of Credit, if the expiry date of such
requested Letter of Credit would occur after the Letter of Credit Expiration Date, unless
all the Lenders have approved such expiry date.

 

21

 

(ii) No Issuing Bank shall be under any obligation to issue any Letter of Credit if:

(A) any order, judgment or decree of any Governmental Authority or arbitrator
shall by its terms purport to enjoin or restrain such Issuing Bank from issuing such
Letter of Credit, or any Law applicable to such Issuing Bank or any request or
directive (whether or not having the force of law) from any Governmental Authority
with jurisdiction over such Issuing Bank shall prohibit, or request that such
Issuing Bank refrain from, the issuance of letters of credit generally or such
Letter of Credit in particular or shall impose upon such Issuing Bank with respect
to such Letter of Credit any restriction, reserve or capital requirement (for which
such Issuing Bank is not otherwise compensated hereunder) not in effect on the
Effective Date, or shall impose upon such Issuing Bank any unreimbursed loss, cost
or expense which was not applicable on the Effective Date and which, in each such
case, such Issuing Bank in good faith deems material to it;

(B) except as otherwise agreed by the Borrower and such Issuing Bank, such
Letter of Credit is in an initial stated amount less than $50,000, in the case of a
commercial Letter of Credit, or $500,000, in the case of a standby Letter of Credit;

(C) such Letter of Credit is to be denominated in a currency other than
Dollars;

(D) such Letter of Credit contains any provisions for automatic reinstatement
of the stated amount after any drawing thereunder;

(E) subject to Section 2.03(b)(iii), the expiry date of such requested Letter
of Credit would occur more than twelve months after the date of issuance or last
extension; or

(F) any Lender is at such time an Affected Lender hereunder, unless the
applicable Issuing Bank is satisfied that the related exposure will be 100% covered
by the Commitments of the non-Affected Lenders or, if not so covered, until such
Issuing Bank has entered into arrangements satisfactory to it in its sole discretion
with the Borrower or such Affected Lender to eliminate such Issuing Bank’s risk with
respect to such Affected Lender, and participating interests in any such newly
issued Letter of Credit shall be allocated among non-Affected
Lenders in a manner consistent with Section 2.19(c)(i) (and Affected Lenders
shall not participate therein);

(iii) No Issuing Bank shall amend any Letter of Credit if such Issuing Bank would not
be permitted at such time to issue such Letter of Credit in its amended form under the terms
hereof.

(iv) No Issuing Bank shall be under any obligation to amend any Letter of Credit if (A)
such Issuing Bank would have no obligation at such time to issue such

 

22

 

Letter of Credit in
its amended form under the terms hereof, or (B) the beneficiary of such Letter of Credit
does not accept the proposed amendment to such Letter of Credit.

(b) Procedures for Issuance and Amendment of Letters of Credit; Auto-Extension Letters of
Credit.

(i) Each Letter of Credit shall be issued or amended, as the case may be, upon the
request of the Borrower delivered to the applicable Issuing Bank (with a copy to the Agent)
in the form of a Letter of Credit Application, appropriately completed and signed by an
Authorized Officer of the Borrower. Such Letter of Credit Application must be received by
such Issuing Bank and the Agent not later than 11:00 a.m. at least two Business Days (or
such later date and time as the Agent and such Issuing Bank may agree in a particular
instance in their sole discretion) prior to the proposed issuance date or date of amendment,
as the case may be. In the case of a request for an initial issuance of a Letter of Credit,
such Letter of Credit Application shall specify in form and detail satisfactory to the
applicable Issuing Bank: (A) the proposed issuance date of the requested Letter of Credit
(which shall be a Business Day); (B) the amount thereof; (C) the expiry date thereof; (D)
the name and address of the beneficiary thereof; (E) the documents to be presented by such
beneficiary in case of any drawing thereunder; (F) the full text of any certificate to be
presented by such beneficiary in case of any drawing thereunder; (G) the purpose and nature
of the requested Letter of Credit; and (H) such other matters as such Issuing Bank may
require. In the case of a request for an amendment of any outstanding Letter of Credit,
such Letter of Credit Application shall specify in form and detail satisfactory to the
applicable Issuing Bank (A) the Letter of Credit to be amended; (B) the proposed date of
amendment thereof (which shall be a Business Day); (C) the nature of the proposed amendment;
and (D) such other matters as such Issuing Bank may require. Additionally, the Borrower
shall furnish to the applicable Issuing Bank and the Agent such other documents and
information pertaining to such requested Letter of Credit issuance or amendment, including
any L/C Related Documents, as the applicable Issuing Bank or the Agent may require. In the
event and to the extent that the provisions of any Letter of Credit Application or other L/C
Related Document shall conflict with this Agreement, the provisions of this Agreement shall
govern. Without limitation of the immediately preceding sentence, no such Letter of Credit
Application or other L/C Related Document may impose any additional conditions on the
issuance or maintenance of a Letter of Credit, any additional default provisions, collateral
requirements or other obligations of the Borrower to any Issuing Bank, other than as stated
in this Agreement.

(ii) Promptly after receipt of any Letter of Credit Application, the applicable Issuing
Bank will confirm with the Agent (by telephone or in writing) that the Agent has received a
copy of such Letter of Credit Application from the Borrower and, if not, such Issuing Bank
will provide the Agent with a copy thereof. Unless the applicable Issuing Bank has received
written notice from the Required Lenders, the Agent or the Borrower, at least one Business
Day prior to the requested date of issuance or amendment of the applicable Letter of Credit,
that one or more applicable conditions contained in Article III shall not then be satisfied,
then, subject to the terms and conditions hereof, such Issuing Bank shall, on the requested
date, issue a Letter of Credit for the account of the Borrower

 

23

 

or enter into the applicable
amendment, as the case may be, in each case in accordance with such Issuing Bank’s usual and
customary business practices. Immediately upon the issuance of each Letter of Credit, each
Lender shall be deemed to, and hereby irrevocably and unconditionally agrees to, purchase
from such Issuing Bank a risk participation in such Letter of Credit in an amount equal to
the product of such Lender’s Ratable Share times the amount of such Letter of Credit.

(iii) If the Borrower so requests in any applicable Letter of Credit Application, the
applicable Issuing Bank may, in its sole and absolute discretion, agree to issue a Letter of
Credit that has automatic extension provisions (each, an “Auto-Extension Letter of
Credit”); provided that any such Auto-Extension Letter of Credit must permit
such Issuing Bank to prevent any such extension at least once in each twelve-month period
(commencing with the date of issuance of such Letter of Credit) by giving prior notice to
the beneficiary thereof not later than a day (the “Non-Extension Notice Date”) in
each such twelve-month period to be agreed upon at the time such Letter of Credit is issued.
Unless otherwise directed by the applicable Issuing Bank, the Borrower shall not be
required to make a specific request to the applicable Issuing Bank for any such extension.
Once an Auto-Extension Letter of Credit has been issued, the Lenders shall be deemed to have
authorized (but may not require) the applicable Issuing Bank to permit the extension of such
Letter of Credit at any time to an expiry date not later than the Letter of Credit
Expiration Date; provided, however, that the applicable Issuing Bank shall
not permit any such extension (or may issue a Notice of Non-Extension) if (A) such Issuing
Bank has determined that it would not be permitted at such time to issue such Letter of
Credit in its revised form (as extended) by reason of the provisions of clause (i) of
Section 2.03(a) (or would have no obligation to issue such Letter of Credit by reason of the
provisions of clause (ii) of Section 2.03(a)), or (B) it has received notice (which may be
by telephone or in writing) on or before the day that is seven Business Days before the
Non-Extension Notice Date (1) from the Agent that the Required Lenders have elected not to
permit such extension pursuant to Section 6.02 or (2) from the Agent, the Required Lenders
or the Borrower that one or more of the applicable conditions specified in Section 3.02 is
not then satisfied, and in each such case directing such Issuing Bank not to permit such
extension.

(iv) Promptly after its delivery of any Letter of Credit or any amendment to a Letter
of Credit to an advising bank with respect thereto or to the beneficiary thereof, the
applicable Issuing Bank will also deliver to the Borrower and the Agent a true and complete
copy of such Letter of Credit or amendment.

(c) Drawings and Reimbursements; Funding of Participations.

(i) Subject to the provisions below, not later than 2:30 p.m. on the date (the
“Honor Date”) that any Issuing Bank makes any payment on a drawing on any Letter of
Credit, if the Borrower shall have received notice of such payment prior to 11:30 a.m. on
such date, or, if such notice has not been received by the Borrower prior to such time on
such date, then not later than 2:30 p.m. on the next Business Day, the Borrower shall
reimburse such Issuing Bank through the Agent in an amount equal to the amount of such
drawing together with interest thereon. If the Borrower fails to so reimburse such Issuing

 

24

 

Bank by such time, unless the Borrower shall have advised the Agent that it does not meet
the conditions specified in either clause (B) or (C) below, the Agent shall promptly notify
each Lender of the Honor Date, the amount of the unreimbursed drawing (the “Unreimbursed
Amount”), and the amount of such Lender’s Ratable Share thereof. In such event, the
Borrower shall be deemed to have requested a Base Rate Advance to be disbursed on the Honor
Date in an amount equal to the Unreimbursed Amount, without regard to the minimum and
multiples specified in Section 2.01(a) or the delivery of a Notice of Borrowing, but subject
to (A) the amount of the aggregate Unused Commitments, (B) no Event of Default having
occurred and be continuing, or resulting therefrom, and (C) the conditions specified in
Sections 3.02(c) through (i) being satisfied on and as of the date of the applicable Base
Rate Advance and, to the extent so financed, the Borrower’s obligation to satisfy the
reimbursement obligation created by such payment by the Issuing Bank on the Honor Date shall
be discharged and replaced by the resulting Base Rate Advance. Any notice given by any
Issuing Bank or the Agent pursuant to this Section 2.03(c)(i) may be given by telephone if
immediately confirmed in writing; provided that the lack of such an immediate
confirmation shall not affect the conclusiveness or binding effect of such notice.

(ii) Each Lender shall upon any notice pursuant to Section 2.03(c)(i) make funds
available to the Agent for the account of the applicable Issuing Bank at the Agent’s Office
in an amount equal to its Ratable Share of the Unreimbursed Amount not later than 4:00 p.m.
on the Business Day specified in such notice by the Agent, whereupon, subject to the
provisions of Section 2.03(c)(iii), each Lender that so makes funds available shall be
deemed to have made a Base Rate Advance to the Borrower in such amount. The Agent shall
remit the funds so received to the applicable Issuing Bank.

(iii) With respect to any Unreimbursed Amount that is not fully refinanced by a Base
Rate Advance because any of the conditions set forth in clauses (A), (B) or (C) of Section
2.03(c)(i) cannot be satisfied or for any other reason, then not later than 2:30 p.m. on the
next Business Day after the day notice of the drawing is given to the Borrower, in the case
of a failure to meet any such condition, or in any other case, after notice of the event
resulting in the outstanding Unreimbursed Amount, the Borrower shall reimburse such Issuing
Bank through the Agent in an amount equal to the amount of such outstanding Unreimbursed
Amount with interest thereon. If the Borrower fails to so reimburse such Issuing Bank by
such time, the Borrower shall be deemed to have incurred from the applicable Issuing Bank an
L/C Borrowing in the amount of the Unreimbursed Amount that is not so refinanced, which L/C
Borrowing shall be due and payable on demand (together with interest) and shall bear
interest at the Base Rate in
effect from time to time plus the Applicable Rate for Base Rate Advances in effect from
time to time plus 2% per annum. In such event, each Lender’s payment to the Agent for the
account of the applicable Issuing Bank pursuant to Section 2.03(c)(ii) shall be deemed
payment in respect of its participation in such L/C Borrowing and shall constitute an L/C
Advance from such Lender in satisfaction of its participation obligation under this Section
2.03.

(iv) Until each Lender funds its Base Rate Advance or L/C Advance pursuant to this
Section 2.03(c) to reimburse the applicable Issuing Bank for any amount drawn

 

25

 

under any
Letter of Credit, interest in respect of such Lender’s Ratable Share of such amount shall be
solely for the account of the applicable Issuing Bank.

(v) Each Lender’s obligation to make Base Rate Advances or L/C Advances to reimburse
the applicable Issuing Bank for amounts drawn under Letters of Credit, as contemplated by
this Section 2.03(c), shall be absolute and unconditional and shall not be affected by any
circumstance, including (A) any setoff, counterclaim, recoupment, defense or other right
which such Lender may have against such Issuing Bank, the Borrower or any other Person for
any reason whatsoever; (B) the occurrence or continuance of a Default, or (C) any other
occurrence, event or condition, whether or not similar to any of the foregoing;
provided, however, that each Lender’s obligation to make Base Rate Advances
pursuant to this Section 2.03(c) is subject to the conditions set forth in Section
2.03(c)(i). No such making of an L/C Advance shall relieve or otherwise impair the
obligation of the Borrower to reimburse the applicable Issuing Bank for the amount of any
payment made by such Issuing Bank under any Letter of Credit, together with interest as
provided herein.

(vi) If any Lender fails to make available to the Agent for the account of the
applicable Issuing Bank any amount required to be paid by such Lender pursuant to the
foregoing provisions of this Section 2.03(c) by the time specified in Section 2.03(c)(ii),
such Issuing Bank shall be entitled to recover from such Lender (acting through the Agent),
on demand, such amount with interest thereon for the period from the date such payment is
required to the date on which such payment is immediately available to such Issuing Bank at
a rate per annum equal to the greater of the Federal Funds Rate and a rate determined by
such Issuing Bank in accordance with banking industry rules on interbank compensation, plus
any administrative, processing or similar fees customarily charged by such Issuing Bank in
connection with the foregoing. If such Lender pays such amount (with interest and fees as
aforesaid), the amount so paid shall constitute such Lender’s Base Rate Advance included in
the relevant Borrowing or L/C Advance in respect of the relevant L/C Borrowing, as the case
may be. A certificate of the applicable Issuing Bank submitted to any Lender (through the
Agent) with respect to any amounts owing under this clause (vi) shall be conclusive absent
manifest error.

(d) Repayment of Participations.

(i) At any time after the applicable Issuing Bank has made a payment under any Letter
of Credit and has received from any Lender such Lender’s L/C Advance in respect of such
payment in accordance with Section 2.03(c), if the Agent receives for the
account of such Issuing Bank any payment in respect of the related Unreimbursed Amount
or interest thereon (whether directly from the Borrower or otherwise, including proceeds of
Cash Collateral (as defined in Section 2.03(h)) applied thereto by the Agent), the Agent
will distribute to such Lender its Ratable Share thereof in the same funds as those received
by the Agent.

(ii) If any payment received by the Agent for the account of the applicable Issuing
Bank pursuant to Section 2.03(c)(i) is required to be returned under any of the
circumstances described in Section 8.12 (including pursuant to any settlement entered

 

26

 

into
by such Issuing Bank in its discretion), each Lender shall pay to the Agent for the account
of such Issuing Bank its Ratable Share thereof on demand of the Agent, plus interest thereon
from the date of such demand to the date such amount is returned by such Lender, at a rate
per annum equal to the Federal Funds Rate from time to time in effect. The obligations of
the Lenders under this clause shall survive the payment in full of the Obligations and the
termination of this Agreement.

(e) Failure to Make Advances. The failure of any Lender to make the Advance to be
made by it on the date specified in Section 2.03(c) or any L/C Advance shall not relieve any other
Lender of its obligation hereunder to make its Advance or L/C Advance, as the case may be, to be
made by such other Lender on such date.

(f) Obligations Absolute. The obligation of the Borrower to reimburse the applicable
Issuing Bank for each drawing under each Letter of Credit and to repay each L/C Borrowing shall be
absolute, unconditional and irrevocable, and shall be paid strictly in accordance with the terms of
this Agreement under all circumstances, including the following:

(i) any lack of validity or enforceability of such Letter of Credit, this Agreement, or
any other Loan Document;

(ii) the existence of any claim, counterclaim, setoff, defense or other right that the
Borrower may have at any time against any beneficiary or any transferee of such Letter of
Credit (or any Person 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 hereby or by such Letter of Credit or any agreement or instrument
relating thereto, or any unrelated transaction;

(iii) any draft, demand, certificate or 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; or any loss or delay in the
transmission or otherwise of any document required in order to make a drawing under such
Letter of Credit;

(iv) any payment by the applicable Issuing Bank under such Letter of Credit against
presentation of a draft or certificate that does not strictly comply with the terms of such
Letter of Credit; or any payment made by the applicable Issuing Bank under such Letter of
Credit to any Person purporting to be a trustee in bankruptcy, debtor-in-possession,
assignee for the benefit of creditors, liquidator, receiver or other
representative of or successor to any beneficiary or any transferee of such Letter of
Credit, including any arising in connection with any proceeding under any Debtor Relief Law;
or

(v) any other circumstance or happening whatsoever, whether or not similar to any of
the foregoing, including any other circumstance that might otherwise constitute a defense
available to, or a discharge of, the Borrower.

provided, however, that nothing in this Section 2.03(f) shall limit the
rights of the Borrower under Section 2.03(g).

 

27

 

The Borrower shall promptly examine a copy of each Letter of Credit and each amendment thereto
that is delivered to it and, in the event of any claim of noncompliance with the Borrower’s
instructions or other irregularity that is known to the Borrower in connection with any draw under
such Letter of Credit of which the Borrower has reasonable notice, the Borrower will immediately
notify the applicable Issuing Bank. To the extent allowed by applicable Law, Borrower shall be
conclusively deemed to have waived any such claim against the applicable Issuing Bank and its
correspondents unless such notice is given as aforesaid. Nothing herein shall require the Borrower
to make any determination as to whether the drawing is in accordance with the requirements of the
Letter of Credit, provided that the Borrower may waive any discrepancies in the drawing on any such
Letter of Credit.

(g) Role of Issuing Bank. Each Lender and the Borrower agree that, in paying any
drawing under a Letter of Credit, the applicable Issuing Bank shall not have any responsibility to
obtain any document (other than any sight draft, certificates and documents expressly required by
the Letter of Credit) or to ascertain or inquire as to the validity or accuracy of any such
document or the authority of the Person executing or delivering any such document. None of the
applicable Issuing Bank, the Agent, any of their respective Related Parties nor any correspondent,
participant or assignee of such Issuing Bank shall be liable to any Lender for (i) any action taken
or omitted in connection herewith at the request or with the approval of the Lenders or the
Required Lenders, as applicable; (ii) any action taken or omitted in the absence of gross
negligence or willful misconduct; or (iii) the due execution, effectiveness, validity or
enforceability of any document or instrument related to any Letter of Credit or L/C Related
Document. The Borrower hereby assumes all risks of the acts or omissions of any beneficiary or
transferee with respect to its use of any Letter of Credit; provided, however, that
this assumption is not intended to, and shall not, preclude the Borrower’s pursuing such rights and
remedies as it may have against the beneficiary or transferee at Law or under any other agreement.
None of the applicable Issuing Bank, the Agent, any of their respective Related Parties nor any
correspondent, participant or assignee of such Issuing Bank shall be liable or responsible for any
of the matters described in clauses (i) through (v) of Section 2.03(f); provided,
however, that anything in such clauses to the contrary notwithstanding, the Borrower may
have a claim against the applicable Issuing Bank, and such Issuing Bank may be liable to the
Borrower, to the extent, but only to the extent, of any direct, as opposed to consequential or
exemplary, damages suffered by the Borrower which the Borrower proves were caused by such Issuing
Bank’s willful misconduct or gross negligence or such Issuing Bank’s willful failure to pay under
any Letter of Credit after the presentation to it by the beneficiary of a sight draft and
certificate(s) strictly complying with the terms and conditions of a Letter of Credit. In
furtherance and not in
limitation of the foregoing, the applicable Issuing Bank may accept documents that appear on
its face to be in order, without responsibility for further investigation, regardless of any notice
or information to the contrary, and such Issuing Bank shall not be responsible for the validity or
sufficiency of any instrument transferring or assigning or purporting to transfer or assign a
Letter of Credit or the rights or benefits thereunder or proceeds thereof, in whole or in part,
which may prove to be invalid or ineffective for any reason.

(h) Cash Collateral. Upon the request of the Agent, if, as of the Letter of Credit
Expiration Date, any L/C Obligation for any reason remains outstanding, the Borrower shall, in each
case, immediately Cash Collateralize the then outstanding L/C Obligations. Section 6.02 sets forth
certain additional requirements to deliver Cash Collateral hereunder. For purposes of

 

28

 

this Section
2.03 and Section 6.02, “Cash Collateralize” means to pledge and deposit with or deliver to the
Agent, for the benefit of the Issuing Banks and the Lenders, as collateral for the L/C Obligations,
cash or deposit account balances pursuant to documentation in form and substance satisfactory to
the Agent and each Issuing Bank (which documents are hereby consented to by the Lenders).
Derivatives of such term have corresponding meanings. The Borrower hereby grants to the Agent, for
the benefit of the Issuing Banks and the Lenders, a security interest in all such cash, deposit
accounts and all balances therein and all proceeds of the foregoing. Cash Collateral shall be
maintained in blocked, non-interest bearing deposit accounts with the Agent.

(i) Applicability of ISP and UCP. Unless otherwise expressly agreed by the applicable
Issuing Bank and the Borrower when a Letter of Credit is issued, (i) the rules of the ISP shall
apply to each standby Letter of Credit, and (ii) the rules of the Uniform Customs and Practice for
Documentary Credits, as most recently published by the International Chamber of Commerce at the
time of issuance shall apply to each commercial Letter of Credit.

(j) Letter of Credit Reports. Each Issuing Bank shall furnish (A) to the Agent on the
first Business Day of each month a written report summarizing issuance and expiration dates of
Letters of Credit issued by such Issuing Bank during the preceding month and drawings during such
month under all such Letters of Credit and (B) to the Agent on the first Business Day of each
calendar quarter a written report setting forth the average daily aggregate Available Amount during
the preceding calendar quarter of all Letters of Credit issued by such Issuing Bank.

(k) Interim Interest. Except as provided in Section 2.03(c)(ii) with respect to
Unreimbursed Amounts refinanced as Base Rate Advances and Section 2.03(c)(iii) with respect to L/C
Borrowings, unless the Borrower shall reimburse each payment by an Issuing Bank pursuant to a
Letter of Credit in full on the Honor Date, the Unreimbursed Amount thereof shall bear interest,
for each day from and including the Honor Date to but excluding the date that the Borrower
reimburses such Issuing Bank for the Unreimbursed Amount in full, at the rate per annum equal to
(i) the Base Rate in effect from time to time plus the Applicable Rate for Base Rate Advances in
effect from time to time, to but excluding the next Business Day after the Honor Date and (ii) from
and including the next Business Day after the Honor Date, the Base Rate in effect from time to time
plus the Applicable Rate for Base Rate Advances in effect from time to time plus 2% per annum.

Section 2.04 Fees.

(a) Commitment Fee. The Borrower agrees to pay to the Agent for the account of each
Lender a commitment fee on such Lender’s Unused Commitment from the Effective Date in the case of
each Initial Lender and from the effective date specified in the Assumption Agreement or in the
Assignment and Assumption pursuant to which it became a Lender in the case of each other Lender
until the Termination Date at a rate per annum equal to the Applicable Rate for Commitment Fees in
effect from time to time, payable in arrears quarterly on the last day of each March, June,
September and December, commencing March 31, 2010, and on the Termination Date, provided that no
commitment fee shall accrue with respect to the Unused Commitment of an Affected Lender so long as
such Lender shall be an Affected Lender.

 

29

 

(b) Letter of Credit Fees.

(i) The Borrower shall pay to the Agent for the account of each Lender a commission on
such Lender’s Ratable Share of the average daily aggregate Available Amount of all Letters
of Credit outstanding from time to time at a rate per annum equal to the Applicable Rate for
Eurodollar Rate Advances in effect from time to time, during such calendar quarter, payable
in arrears quarterly on the last day of each March, June, September and December, commencing
with the quarter ended March 31, 2010, and on the Termination Date; provided that
the Applicable Rate for Eurodollar Rate Advances shall be 2% above such Applicable Rate in
effect upon the occurrence and during the continuation of an Event of Default if the
Borrower is required to pay default interest pursuant to Section 2.07(b).

(ii) The Borrower shall pay to each Issuing Bank, for its own account, a fronting fee
with respect to each Letter of Credit issued by such Issuing Bank, payable in the amounts
and at the times specified in the applicable Fee Letter between the Borrower and such
Issuing Bank, and such other commissions, issuance fees, transfer fees and other fees and
charges in connection with the issuance or administration of each Letter of Credit as the
Borrower and such Issuing Bank shall agree promptly following receipt of an invoice
therefor.

(c) Agent’s Fees. The Borrower shall pay to the Agent for its own account such fees
as are agreed between the Borrower and the Agent pursuant to the Fee Letter between the Borrower
and the Agent.

Section 2.05 Optional Termination or Reduction of the Commitments.

(a) The Borrower shall have the right, upon at least three Business Days’ notice to the Agent,
to terminate in whole or permanently reduce ratably in part the Unused Commitments or the Unissued
Letter of Credit Commitments, provided that each partial reduction shall be in the
aggregate amount of $10,000,000 or an integral multiple of $1,000,000 in excess thereof.

(b) So long as no Default or Event of Default shall be continuing, the Borrower shall have the
right, at any time, upon at least ten Business Days’ notice to an Affected Lender (with a copy to
the Agent), to terminate in whole such Lender’s Revolving Credit Commitment and, if applicable, its
Letter of Credit Commitment, without affecting the Commitments of any other
Lender. Such termination shall be effective, (x) with respect to such Lender’s Unused
Commitment, on the date set forth in such notice, provided, however, that such date
shall be no earlier than ten Business Days after receipt of such notice and (y) with respect to
each Advance outstanding to such Lender, in the case of Base Rate Advances, on the date set forth
in such notice and, in the case of Eurodollar Rate Advances, on the last day of the then current
Interest Period relating to such Advance. Upon termination of a Lender’s Commitments under this
Section 2.05(b), the Borrower will pay or cause to be paid all principal of, and interest accrued
to the date of such payment on, Advances owing to such Lender and, subject to Section 2.19, pay any
accrued commitment fees or Letter of Credit fees payable to such Lender pursuant to the provisions
of Section 2.04, and all other amounts payable to such Lender hereunder (including, but not limited
to, any increased costs or other amounts owing under Section 2.11 and any

 

30

 

indemnification for Taxes
under Section 2.14); and, if such Lender is an Issuing Bank, shall pay to such Issuing Bank for
deposit in an escrow account an amount equal to the Available Amount of all Letters of Credit
issued by such Issuing Bank, whereupon all Letters of Credit issued by such Issuing Bank shall be
deemed to have been issued outside of this Agreement on a bilateral basis and shall cease for all
purposes to constitute a Letter of Credit issued under this Agreement, and upon such payments,
except as otherwise provided below, the obligations of such Lender hereunder shall, by the
provisions hereof, be released and discharged; provided, however, that (i) such
Lender’s rights under Sections 2.11, 2.14 and 8.04, and, in the case of an Issuing Bank, Section
8.04(c), and its obligations under Section 8.04 and 8.08, in each case in accordance with the terms
thereof, shall survive such release and discharge as to matters occurring prior to such date and
(ii) such escrow agreement shall be in a form reasonably agreed to by the Borrower and such Issuing
Bank, but in no event shall either the Borrower or such Issuing Bank require any waivers,
covenants, events of default or other provisions that are more restrictive than or inconsistent
with the provisions of this Agreement. Subject to Section 2.18, the aggregate amount of the
Commitments of the Lenders once reduced pursuant to this Section 2.05(b) may not be reinstated.
The termination of the Commitments of an Affected Lender pursuant to this Section 2.05(b) will not
be deemed to be a waiver of any right that the Borrower, the Agent, any Issuing Bank or any other
Lender may have against the Affected Lender that arose prior to the date of such termination. Upon
any such termination, the Ratable Share of each remaining Lender will be revised.

Section 2.06 Repayment of Advances. The Borrower shall repay to the Agent for the ratable account of the Lenders on the
Termination Date the aggregate principal amount of the Advances made by such Lender and then
outstanding.

Section 2.07 Interest on Advances.

(a) Scheduled Interest. The Borrower shall pay interest on the unpaid principal
amount of each Advance owing to each Lender from the date of such Advance until such principal
amount shall be paid in full, at the following rates per annum:

(i) Base Rate Advances. During such periods as such Advance is a Base Rate
Advance, a rate per annum equal at all times to the sum of (x) the Base Rate in effect from
time to time plus (y) the Applicable Rate for Base Rate Advances in effect from
time to time, payable in arrears quarterly on the last day of each March, June,
September and December during such periods and on the date such Base Rate Advance shall be
Converted or paid in full.

(ii) Eurodollar Rate Advances. During such periods as such Advance is a
Eurodollar Rate Advance, a rate per annum equal at all times during each Interest Period for
such Advance to the sum of (x) the Eurodollar Rate for such Interest Period for such Advance
plus (y) the Applicable Rate for Eurodollar Rate Advances in effect from time to
time, payable in arrears on the last day of such Interest Period and, if such Interest
Period has a duration of more than three months, on each day that occurs during such
Interest Period every three months from the first day of such Interest Period and on the
date such Eurodollar Rate Advance shall be Converted or paid in full.

 

31

 

(b) Default Interest. Upon the occurrence and during the continuance of an Event of
Default under Section 6.01(a), the Agent may, and upon the request of the Required Lenders shall,
require the Borrower to pay interest (“Default Interest”) on (i) the unpaid principal
amount of each Advance owing to each Lender, payable in arrears on the dates referred to in clause
(a)(i) or (a)(ii) above, at a rate per annum equal at all times to 2% per annum above the rate per
annum required to be paid on such Advance pursuant to clause (a)(i) or (a)(ii) above and (ii) to
the fullest extent permitted by Law, the amount of any interest, fee or other amount payable
hereunder that is not paid when due, from the date such amount shall be due until such amount shall
be paid in full, payable in arrears on the date such amount shall be paid in full and on demand, at
a rate per annum equal at all times to 2% per annum above the rate per annum required to be paid on
Base Rate Advances pursuant to clause (a)(i) above, provided, however, that
following acceleration of the Advances pursuant to Section 6.01, Default Interest shall accrue and
be payable hereunder whether or not previously required by the Agent.

(c) Interest Rate Limitation. Nothing contained in this Agreement or in any other
Loan Document shall be deemed to establish or require the payment of interest to any Lender at a
rate in excess of the maximum rate permitted by applicable Law. If the amount of interest payable
for the account of any Lender on any interest payment date would exceed the maximum amount
permitted by applicable Law to be charged by such Lender, the amount of interest payable for its
account on such interest payment date shall be automatically reduced to such maximum permissible
amount. In the event of any such reduction affecting any Lender, if from time to time thereafter
the amount of interest payable for the account of such Lender on any interest payment date would be
less than the maximum amount permitted by applicable Law to be charged by such Lender, then the
amount of interest payable for its account on such subsequent interest payment date shall be
automatically increased to such maximum permissible amount, provided that at no time shall the
aggregate amount by which interest paid for the account of any Lender has been increased pursuant
to this sentence exceed the aggregate amount by which interest paid for its account has theretofore
been reduced pursuant to the previous sentence.

Section 2.08 Interest Rate Determination.

(a) The Agent shall give prompt notice to the Borrower and the Lenders of the applicable
interest rate determined by the Agent for purposes of Section 2.07(a).

(b) If the Required Lenders determine that for any reason in connection with any request for a
Eurodollar Rate Advance or a Conversion to or continuation thereof that (a) Dollar deposits are not
being offered to banks in the London interbank eurodollar market for the applicable amount and
Interest Period of such Eurodollar Rate Advance, (b) adequate and reasonable means do not exist for
determining the Eurodollar Rate for any requested Interest Period with respect to a proposed
Eurodollar Rate Advance, or (c) the Eurodollar Rate for any requested Interest Period with respect
to a proposed Eurodollar Rate Advance does not adequately and fairly reflect the cost to such
Lenders of funding such Advance, the Agent will promptly so notify the Borrower and each Lender,
whereupon each Eurodollar Rate Advance will automatically on the last day of the then existing
Interest Period therefor Convert into a Base Rate Advance. Thereafter, the obligation of the
Lenders to make or maintain Eurodollar Rate Advances shall be suspended until the Agent (upon the
instruction of the Required Lenders)

 

32

 

revokes such notice. Upon receipt of such notice, the
Borrower may revoke any pending request for a Borrowing of, Conversion to or continuation of
Eurodollar Rate Advances or, failing that, will be deemed to have Converted such request into a
request for a Base Rate Advance in the amount specified therein.

(c) If the Borrower shall fail to select the duration of any Interest Period for any
Eurodollar Rate Advances in accordance with the provisions contained in the definition of “Interest
Period” in Section 1.01, the Agent will forthwith so notify the Borrower and the Lenders and such
Advances will automatically, on the last day of the then existing Interest Period therefor, Convert
into Base Rate Advances.

(d) On the date on which the aggregate unpaid principal amount of Eurodollar Rate Advances
comprising any Borrowing shall be reduced, by payment or prepayment or otherwise, to less than
$10,000,000, such Advances shall automatically Convert into Base Rate Advances.

(e) Upon the occurrence and during the continuance of any Event of Default,

(i) with respect to Eurodollar Rate Advances, each such Advance will automatically, on
the last day of the then existing Interest Period therefor, Convert into a Base Rate Advance
(or if such Advance is then a Base Rate Advance, will continue as a Base Rate Advance); and

(ii) the obligation of the Lenders to make Eurodollar Rate Advances or to Convert
Advances into Eurodollar Rate Advances shall be suspended until the Agent shall notify the
Borrower and the Lenders that the circumstances causing such suspension no longer exist.

Section 2.09 Optional Conversion of Advances. The Borrower may on any Business Day, upon notice given to the Agent not later than 12:00
noon on the third Business Day prior to the date of the proposed Conversion and subject to the
provisions of Sections 2.08 and 2.12, Convert all Advances of one Type comprising the same
Borrowing into Advances of the other Type; provided, however, that (a) any
Conversion of Eurodollar Rate Advances into Base Rate Advances shall be made only on the last day
of an Interest Period for such Eurodollar Rate Advances, (b) any Conversion of Base Rate Advances
into Eurodollar Rate Advances shall be in an amount not less than the minimum amount specified
in Section 2.02(b) and (c) no Conversion of any Advances shall result in more separate Borrowings
than permitted under Section 2.02(b). Each such notice of a Conversion shall, within the
restrictions specified above, specify (i) the date of such Conversion, (ii) the Advances to be
Converted, and (iii) if such Conversion is into Eurodollar Rate Advances, the duration of the
initial Interest Period for each such Advance. Each notice of Conversion shall be irrevocable and
binding on the Borrower.

Section 2.10 Prepayments of Advances.

(a) Optional. At any time and from time to time, the Borrower shall have the right to
prepay the Advances, in whole or in part, without premium or penalty (except as provided in clause
(y) below), upon notice at least two Business Days’ prior to the date of such prepayment, in the
case of Eurodollar Rate Advances, and not later than 11:00 a.m. on the date of such prepayment, in
the case of Base Rate Advances, to the Agent specifying the proposed date of

 

33

 

such prepayment and
the aggregate principal amount and Type of the Advances to be prepaid (and, in the case of
Eurodollar Rate Advances, the Interest Period of the Borrowing pursuant to which made);
provided, however, that (x) each partial prepayment shall be in an aggregate
principal amount of $10,000,000 or an integral multiple of $1,000,000 in excess thereof and (y) in
the event of any such prepayment of a Eurodollar Rate Advance, the Borrower shall be obligated to
reimburse the Lenders in respect thereof pursuant to Section 8.04(e).

(b) Mandatory.

(i) The Borrower shall prepay the aggregate principal amount of the Advances, together
with accrued interest to the date of prepayment on the principal amount prepaid, without
requirement of demand therefor, or shall pay or prepay any other Indebtedness then
outstanding at any time, when and to the extent required to comply with applicable Laws of
any Governmental Authority, including the 2007 Order, or applicable resolutions of the Board
of Directors of the Borrower.

(ii) If for any reason the Total Outstandings at any time exceed the aggregate
Commitments then in effect, the Borrower shall, within one Business Day after notice
thereof, prepay Advances and/or Cash Collateralize the L/C Obligations in an aggregate
amount equal to such excess; provided, however, that the Borrower shall not
be required to Cash Collateralize the L/C Obligations pursuant to this Section 2.10(b)
unless, after the prepayment in full of the Advances, the Total Outstandings exceed the
aggregate Commitments then in effect.

Section 2.11 Increased Costs.

(a) Increased Costs Generally. If any Change in Law shall:

(i) impose, modify or deem applicable any reserve, special deposit, compulsory loan,
insurance charge or similar requirement against assets of, deposits with or for the account
of, or credit extended or participated in by, any Lender (except any reserve requirement
contemplated by Section 2.11(e)) or any Issuing Bank; or

(ii) impose on any Lender or any Issuing Bank or the London interbank market any other
condition, cost or expense affecting this Agreement or Eurodollar Rate Loans made by such
Lender or any Letter of Credit or participation therein;

and the result of any of the foregoing shall be to increase the cost to such Lender of making or
maintaining any Eurodollar Rate Advance (or of maintaining its obligation to make any such
Advance), or to increase the cost to such Lender or such Issuing Bank of participating in, issuing
or maintaining any Letter of Credit (or of maintaining its obligation to participate in or to issue
any Letter of Credit), or to reduce the amount of any sum received or receivable by such Lender or
such Issuing Bank hereunder (whether of principal, interest or any other amount) then, upon request
of such Lender or such Issuing Bank, the Borrower will pay to such Lender or such Issuing Bank, as
the case may be, such additional amount or amounts as will compensate such Lender or such Issuing
Bank, as the case may be, for such additional costs incurred or reduction suffered.

 

34

 

(b) Capital Requirements. If any Lender or any Issuing Bank determines that any
Change in Law affecting such Lender or such Issuing Bank or any Applicable Lending Office of such
Lender or such Lender’s or such Issuing Bank’s holding company, if any, regarding capital
requirements has or would have the effect of reducing the rate of return on such Lender’s or such
Issuing Bank’s capital or on the capital of such Lender’s or such Issuing Bank’s holding company,
if any, as a consequence of this Agreement, the Commitments of such Lender or the Advances made by,
or participations in Letters of Credit held by, such Lender, or the Letters of Credit issued by
such Issuing Bank, to a level below that which such Lender or such Issuing Bank or such Lender’s or
such Issuing Bank’s holding company could have achieved but for such Change in Law (taking into
consideration such Lender’s or such Issuing Bank’s policies and the policies of such Lender’s or
such Issuing Bank’s holding company with respect to capital adequacy), then from time to time the
Borrower will pay to such Lender or such Issuing Bank, as the case may be, such additional amount
or amounts as will compensate such Lender or such Issuing Bank or such Lender’s or such Issuing
Bank’s holding company for any such reduction suffered.

(c) Certificates for Reimbursement. A certificate of a Lender or an Issuing Bank
setting forth the amount or amounts necessary to compensate such Lender or such Issuing Bank or its
holding company, as the case may be, as specified in subsection (a) or (b) of this Section and
delivered to the Borrower shall be conclusive absent manifest error. The Borrower shall pay such
Lender or such Issuing Bank, as the case may be, the amount shown as due on any such certificate
within 30 days after receipt thereof.

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

(e) Reserves on Eurodollar Rate Loans. The Borrower shall pay to each Lender, as long
as such Lender shall be required to maintain reserves with respect to liabilities or assets
consisting of or including Eurocurrency funds or deposits (currently known as “Eurocurrency
liabilities”), additional interest on the unpaid principal amount of each Eurodollar Rate Advance
equal to the actual costs of such reserves allocated to such Advance by such Lender (as determined
by such Lender in good faith, which determination shall be conclusive absent manifest error), which
shall be due and payable on each date on which interest is payable on such Loan, provided
the Borrower shall have received at least 30 days’ prior notice (with a copy to the Agent) of such
additional interest from such Lender. If a Lender fails to give notice 30 days prior to the
relevant interest payment date, such additional interest shall be due and payable 30 days from
receipt of such notice.

 

35

 

Section 2.12 Illegality. If any Lender shall have determined in good faith that the introduction of or any change in
any applicable Law or in the interpretation or administration thereof by any Governmental Authority
charged with the interpretation or administration thereof, or compliance with any guideline or
request from any such Governmental Authority (whether or not having the force of law), for any
Lender or its Applicable Lending Office to make, maintain or fund Eurodollar Rate Advances, or to
determine or charge interest rates based upon the Eurodollar Rate, or any Governmental Authority
has imposed material restrictions on the authority of such Lender to purchase or sell, or to take
deposits of, Dollars in the London interbank market, then, on notice thereof by such Lender to the
Borrower through the Agent, any obligation of such Lender to make or continue Eurodollar Rate
Advances or to convert Base Rate Advances to Eurodollar Rate Advances shall be suspended until such
Lender notifies the Agent and the Borrower that the circumstances giving rise to such determination
no longer exist. Upon receipt of such notice, the Borrower shall, upon demand from such Lender
(with a copy to the Agent), prepay or, if applicable, convert all Eurodollar Rate Advances of such
Lender to Base Rate Advances, either on the last day of the Interest Period therefor, if such
Lender may lawfully continue to maintain such Eurodollar Rate Advances to such day, or immediately,
if such Lender may not lawfully continue to maintain such Eurodollar Rate Advances. Upon any such
prepayment or conversion, the Borrower shall also pay accrued interest on the amount so prepaid or
converted.

Section 2.13 Payments and Computations.

(a) All payments to be made by the Borrower shall be made without condition or deduction for
any counterclaim, defense, recoupment or setoff. The Borrower shall make each payment hereunder
not later than 1:00 p.m. on the day when due in U.S. dollars to the Agent at the Agent’s Account in
same day funds. The Agent will promptly thereafter cause to be distributed like funds relating to
the payment of principal, interest, fees or commissions ratably (other than amounts payable
pursuant to Section 2.05(b), 2.11, 2.12, 2.14, 2.20 or 8.04(e)) to the Lenders for the account of
their respective Applicable Lending Offices, and like funds relating to the payment of any other
amount payable to any Lender to such Lender for the account of its Applicable Lending Office, in
each case to be applied in accordance with the terms of this
Agreement. Upon any Assuming Lender becoming a Lender hereunder as a result of a Commitment
Increase pursuant to Section 2.18, and upon the Agent’s receipt of such Lender’s Assumption
Agreement and recording of the information contained therein in the Register, from and after the
applicable Increase Date, the Agent shall make all payments hereunder and under any Notes issued in
connection therewith in respect of the interest assumed thereby to the Assuming Lender. Upon its
acceptance of an Assignment and Assumption and recording of the information contained therein in
the Register pursuant to Section 8.07(c), from and after the effective date specified in such
Assignment and Assumption, the Agent shall make all payments hereunder and under the Notes in
respect of the interest assigned thereby to the Lender assignee thereunder, and the parties to such
Assignment and Assumption shall make all appropriate adjustments in such payments for periods prior
to such effective date directly between themselves.

(b) All computations of interest based on the Base Rate or the Federal Funds Rate shall be
made by the Agent on the basis of a year of 365 or 366 days, as the case may be, and all
computations of interest based on the Eurodollar Rate and of fees and Letter of Credit

 

36

 

commissions
shall be made by the Agent on the basis of a year of 360 days, in each case for the actual number
of days (including the first day but excluding the last day) occurring in the period for which such
interest, fees or commissions are payable. Each determination by the Agent of an interest rate
hereunder shall be conclusive and binding for all purposes, absent manifest error.

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

(d) Unless the 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 Agent may assume that the Borrower has made such payment in full to the Agent on such date and
the 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 Agent, each Lender shall repay to the 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 Agent, at the Federal Funds Rate.

Section 2.14 Taxes.

(a) Payments Free of Taxes; Obligation to Withhold; Payments on Account of Taxes.

(i) Any and all payments by or on account of any obligation of the Borrower hereunder
or under any other Loan Document shall to the extent permitted by applicable Laws be made
free and clear of and without reduction or withholding for any Taxes. If, however,
applicable Laws require the Borrower or the Agent to withhold or deduct any Tax, such Tax
shall be withheld or deducted in accordance with such Laws as determined
by the Borrower or the Agent, as the case may be, upon the basis of the information and
documentation to be delivered pursuant to subsection (e) below.

(ii) If the Borrower or the Agent shall be required by the Internal Revenue Code to
withhold or deduct any Taxes, including both United States Federal backup withholding and
withholding taxes, from any payment, then (A) the Agent shall withhold or make such
deductions as are determined by the Agent to be required based upon the information and
documentation it has received pursuant to subsection (e) below, (B) the Agent shall timely
pay the full amount withheld or deducted to the relevant Governmental Authority in
accordance with the Internal Revenue Code, and (C) to the extent that the withholding or
deduction is made on account of Indemnified Taxes or Other Taxes, the sum payable by the
Borrower shall be increased as necessary so that after any required withholding or the
making of all required deductions (including deductions applicable to additional sums
payable under this Section) the Agent, Lender or Issuing Bank, as the case may be, receives
an amount equal to the sum it would have received had no such withholding or deduction been
made.

 

37

 

(b) Payment of Other Taxes by the Borrower. Without limiting the provisions of
subsection (a) above, the Borrower shall timely pay any Other Taxes to the relevant Governmental
Authority in accordance with applicable Laws.

(c) Tax Indemnifications.

(i) Without limiting the provisions of subsection (a) or (b) above, the Borrower shall,
and does hereby, indemnify the Agent, each Lender and each Issuing Bank, and shall make
payment in respect thereof within 30 days after written demand therefor, for the full amount
of any Indemnified Taxes or Other Taxes (including Indemnified Taxes or Other Taxes imposed
or asserted on or attributable to amounts payable under this Section) withheld or deducted
by the Borrower or the Agent or paid by the Agent, such Lender or such Issuing Bank, as the
case may be, and any penalties, interest and reasonable expenses arising therefrom or with
respect thereto, whether or not such Indemnified Taxes or Other Taxes were correctly or
legally imposed or asserted by the relevant Governmental Authority. The Borrower shall
also, and does hereby, indemnify the Agent, and shall make payment in respect thereof within
10 days after demand therefor, for any amount which a Lender or an Issuing Bank for any
reason fails to pay indefeasibly to the Agent as required by clause (ii) of this subsection.
A certificate as to the amount of any such payment or liability delivered to the Borrower
by a Lender or an Issuing Bank (with a copy to the Agent), or by the Agent on its own behalf
or on behalf of a Lender or an Issuing Bank, shall be conclusive absent manifest error.

(ii) Without limiting the provisions of subsection (a) or (b) above, each Lender and
each Issuing Bank shall, and does hereby, indemnify the Borrower and the Agent, and shall
make payment in respect thereof within 30 days after demand therefor, against any and all
Taxes and any and all related losses, claims, liabilities, penalties, interest and expenses
(including the fees, charges and disbursements of any counsel for the Borrower or the Agent)
incurred by or asserted against the Borrower or the Agent by any Governmental Authority as a
result of the failure by such Lender or such Issuing
Bank, as the case may be, to deliver, or as a result of the inaccuracy, inadequacy or
deficiency of, any documentation required to be delivered by such Lender or such Issuing
Bank, as the case may be, to the Borrower or the Agent pursuant to subsection (e). Each
Lender and each Issuing Bank hereby authorizes the Agent to set off and apply any and all
amounts at any time owing to such Lender or such Issuing Bank, as the case may be, under
this Agreement or any other Loan Document against any amount due to the Agent under this
clause (ii). The agreements in this clause (ii) shall survive the resignation and/or
replacement of the Agent, any assignment of rights by, or the replacement of, a Lender or an
Issuing Bank, the termination of the Commitments and the repayment, satisfaction or
discharge of all other Obligations.

(d) Evidence of Payments. Upon request by the Borrower or the Agent, as the case may
be, after any payment of Taxes by the Borrower or by the Agent to a Governmental Authority as
provided in this 2.14, the Borrower shall deliver to the Agent or the Agent shall deliver to the
Borrower, as the case may be, the original or a certified copy of a receipt issued by such
Governmental Authority evidencing such payment, a copy of any return required by Laws

 

38

 

to report
such payment or other evidence of such payment reasonably satisfactory to the Borrower or the
Agent, as the case may be.

(e) Status of Lenders; Tax Documentation.

(i) Each Lender shall deliver to the Borrower and to the Agent, at the time or times
prescribed by applicable Laws or when reasonably requested by the Borrower or the 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 Borrower or the Agent, as the case may be, to determine (A) whether or not
payments made hereunder or under any other Loan Document are subject to Taxes, (B) if
applicable, the required rate of withholding or deduction, and (C) such Lender’s entitlement
to any available exemption from, or reduction of, applicable Taxes in respect of all
payments to be made to such Lender by the Borrower pursuant to this Agreement or otherwise
to establish such Lender’s status for withholding tax purposes in the applicable
jurisdiction.

(ii) Without limiting the generality of the foregoing, if the Borrower is resident for
tax purposes in the United States,

(A) any Lender that is a “United States person” within the meaning of Section
7701(a)(30) of the Internal Revenue Code shall deliver to the Borrower and the 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 Borrower
or the Agent as will enable the Borrower or the Agent, as the case may be, to
determine whether or not such Lender is subject to backup withholding or information
reporting requirements; and

(B) each Foreign Lender 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 or under any other Loan Document shall
deliver to the Borrower and the Agent (in such number of copies as shall be
requested by the recipient) on or prior to the date on which such Foreign Lender
becomes a Lender under this Agreement (and from time to time thereafter upon the
request of the Borrower or the Agent, but only if such Foreign Lender is legally
entitled to do so), whichever of the following is applicable:

(1) 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,

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

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

 

39

 

(4) in the case of a Foreign Lender claiming the benefits of the
exemption for portfolio interest under section 881(c) of the Internal
Revenue Code, (x) a certificate to the effect that such Foreign Lender is
not (A) a “bank” within the meaning of section 881(c)(3)(A) of the Internal
Revenue Code, (B) a “10 percent shareholder” of the Borrower within the
meaning of section 881(c)(3)(B) of the Internal Revenue Code, or (C) a
“controlled foreign corporation” described in section 881(c)(3)(C) of the
Internal Revenue Code and (y) executed originals of Internal Revenue
Service Form W-8BEN, or

(5) 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 Borrower or the Agent to
determine the withholding or deduction required to be made.

(iii) Each Lender shall promptly (A) notify the Borrower and the Agent of any change in
circumstances which would modify or render invalid any claimed exemption or reduction, and
(B) take such steps as shall not be materially disadvantageous to it, in the reasonable
judgment of such Lender, and as may be reasonably necessary (including the re-designation of
its Applicable Lending Office) to avoid any requirement of applicable Laws of any
jurisdiction that the Borrower or the Agent make any withholding or deduction for taxes from
amounts payable to such Lender.

(f) Treatment of Certain Refunds. Unless required by applicable Laws, at no time
shall the Agent have any obligation to file for or otherwise pursue on behalf of a Lender or an
Issuing Bank, or have any obligation to pay to any Lender or any Issuing Bank, any refund of Taxes
withheld or deducted from funds paid for the account of such Lender or such Issuing Bank, as the
case may be. If the Agent, any Lender or any Issuing Bank determines, in its sole discretion, that
it has received a refund of any Taxes or Other Taxes as to which it has been
indemnified by the Borrower or with respect to which the Borrower has paid additional amounts
pursuant to this Section, it shall pay to the Borrower an amount equal to such refund (but only to
the extent of indemnity payments made, or additional amounts paid, by the Borrower under this
Section with respect to the Taxes or Other Taxes giving rise to such refund), net of all reasonable
out-of-pocket expenses incurred by the Agent, such Lender or such Issuing Bank, as the case may be,
and without interest (other than any interest paid by the relevant Governmental Authority with
respect to such refund), provided that the Borrower, upon the request of the Agent, such
Lender or such Issuing Bank, agrees to repay the amount paid over to the Borrower (plus any
penalties, interest or other charges imposed by the relevant Governmental Authority) to the Agent,
such Lender or such Issuing Bank in the event the Agent, such Lender or such Issuing Bank is
required to repay such refund to such Governmental Authority. This subsection shall not be
construed to require the Agent, any Lender or any Issuing Bank to make available its tax returns
(or any other information relating to its taxes that it deems confidential) to the Borrower or any
other Person.

 

40

 

(g) Payments. Failure or delay on the part of the Agent, any Lender or any Issuing
Bank to demand compensation pursuant to the foregoing provisions of this Section 2.14 shall not
constitute a waiver of the Agent’s, such Lender’s or such Issuing Bank’s right to demand such
compensation, provided that the Borrower shall not be required to compensate the Agent, a
Lender or an Issuing Bank pursuant to the foregoing provisions of this Section 2.14 for any
Indemnified Taxes or Other Taxes imposed or asserted by the relevant Governmental Authority more
than three months prior to the date that the Agent, such Lender or such Issuing Bank, as the case
may be, claims compensation with respect thereto (except that, if a Change in Law giving rise to
such Indemnified Taxes or Other Taxes is retroactive, then the three-month period referred to above
shall be extended to include the period of retroactive effect thereof).

(h) Each of the Agent, any Issuing Bank or any Lender agrees to cooperate with any reasonable
request made by the Borrower in respect of a claim of a refund in respect of Indemnified Taxes as
to which it has been indemnified by the Borrower or with respect to which the Borrower has paid
additional amounts pursuant to this Section 2.14 if (i) the Borrower has agreed in writing to pay
all of the Agent’s or such Issuing Bank’s or such Lender’s reasonable out-of-pocket costs and
expenses relating to such claim, (ii) the Agent or such Issuing Bank or such Lender determines, in
its good faith judgment, that it would not be disadvantaged, unduly burdened or prejudiced as a
result of such claim and (iii) the Borrower furnishes, upon request of the Agent, or such Issuing
Bank or such Lender, an opinion of tax counsel (such opinion, which can be reasoned, and such
counsel to be reasonably acceptable to such Lender, or such Issuing Bank or the Agent) that the
Borrower is likely to receive a refund or credit.

Section 2.15 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 Advances or L/C Advances owing to
it (other than pursuant to Section 2.05(b), 2.11, 2.12, 2.14, 2.20 or 8.04(e) or any payment
obtained by a Lender as consideration for the assignment of or sale of a participation in any of
its Advances or participations in Letters of Credit to any assignee or participant, other than to
the Borrower or any Subsidiary thereof if permitted hereby (as to which the provisions of this
Section 2.15 shall apply) in excess of its Ratable Share of payments on account of the
Advances obtained by all the Lenders, such Lender shall forthwith purchase from the other
Lenders (for cash at face value) such participations in the Advances 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 2.15 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.

 

41

 

Section 2.16 Evidence of Debt.

(a) Each Lender shall maintain in accordance with its usual practice an account or accounts
evidencing the indebtedness of the Borrower to such Lender resulting from each Advance owing to
such Lender from time to time, including the amounts of principal and interest payable and paid to
such Lender from time to time hereunder in respect of Advances. The Borrower agrees that upon
notice by any Lender to the Borrower (with a copy of such notice to the Agent) to the effect that a
Note is required or appropriate in order for such Lender to evidence (whether for purposes of
pledge, enforcement or otherwise) the Advances owing to, or to be made by, such Lender, the
Borrower shall promptly execute and deliver to such Lender a Note payable to the order of such
Lender in a principal amount up to the Revolving Credit Commitment of such Lender.

(b) The Register maintained by the Agent pursuant to Section 8.07(c) shall include a control
account, and a subsidiary account for each Lender, in which accounts (taken together) shall be
recorded (i) the date and amount of each Borrowing made hereunder, the Type of Advances comprising
such Borrowing and, if appropriate, the Interest Period applicable thereto, (ii) the terms of each
Assumption Agreement and each Assignment and Assumption delivered to and accepted by it, (iii) the
amount of any principal or interest due and payable or to become due and payable from the Borrower
to each Lender hereunder and (iv) the amount of any sum received by the Agent from the Borrower
hereunder and each Lender’s share thereof.

(c) Entries made in good faith by the Agent in the Register pursuant to subsection (b) above,
and by each Lender in its account or accounts pursuant to subsection (a) above, shall be
prima facie evidence of the amount of principal and interest due and payable or to
become due and payable from the Borrower to, in the case of the Register, each Lender and, in the
case of such account or accounts, such Lender, under this Agreement, absent manifest error;
provided, however, that the failure of the Agent or such Lender to make an entry,
or any finding that an entry is incorrect, in the Register or such account or accounts shall not
limit or otherwise affect the obligations of the Borrower under this Agreement.

Section 2.17 Use of Proceeds. The proceeds of the Advances shall be available (and the Borrower agrees that it shall use
such proceeds) solely to refinance Indebtedness of the Borrower from time to time and for other
general corporate purposes of the Borrower, subject to such restrictions that are imposed in the
2007 Order.

Section 2.18 Increase in the Aggregate Revolving Credit Commitments.

(a) The Borrower may, at any time prior to the Termination Date, by notice to the Agent,
request that the aggregate amount of the Revolving Credit Commitments be increased by an amount of
$10,000,000 or an integral multiple thereof (each a “Commitment Increase”) to be effective
as of a date that is at least 90 days prior to the Termination Date (the “Increase Date”)
as specified in the related notice to the Agent; provided, however that (i) in no
event shall the aggregate amount of the Revolving Credit Commitments at any time exceed
$700,000,000 or the aggregate amount of Commitment Increases exceed $200,000,000 and (ii) on the
date of any request by the Borrower for a Commitment Increase and on the related Increase Date, the
applicable conditions set forth in this Section 2.18 shall be satisfied.

 

42

 

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

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

(d) On each Increase Date, each Eligible Assignee that accepts an offer to participate in a
requested Commitment Increase in accordance with Section 2.18(b) (each such Eligible Assignee, an
“Assuming Lender”) shall become a Lender party to this Agreement as of such Increase Date
and the Revolving Credit Commitment of each Increasing Lender for such requested Commitment
Increase shall be so increased by the amount by which the Increasing Lender agreed to increase its
Revolving Credit Commitment (or by the amount allocated to such
Lender pursuant to the last sentence of Section 2.18(b)) as of such Increase Date;
provided, however, that the Agent shall have received on or before such Increase
Date the following, each dated such date:

(i) (A) certified copies of resolutions of the Board of Directors of the Borrower
approving the Commitment Increase and the corresponding modifications to this Agreement, (B)
an opinion of counsel for the Borrower (which may be in-house counsel), in form and
substance reasonably acceptable to the Required Lenders and (C) a certificate from a duly
authorized officer of the Borrower, stating that the conditions set forth in Section 3.02(a)
and (b) are satisfied;

(ii) an assumption agreement from each Assuming Lender, if any, in form and substance
satisfactory to the Borrower and the Agent (each an “Assumption Agreement”), duly
executed by such Assuming Lender, the Agent and the Borrower; and

 

43

 

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

On each Increase Date, upon fulfillment of the conditions set forth in the immediately preceding
sentence of this Section 2.18(d), the Agent shall notify the Lenders (including, without
limitation, each Assuming Lender) and the Borrower, on or before 1:00 p.m., by telecopier, of the
occurrence of the Commitment Increase to be effected on such Increase Date and shall record in the
Register the relevant information with respect to each Increasing Lender and each Assuming Lender
on such date. Each Increasing Lender and each Assuming Lender shall, before 2:00 p.m. on the
Increase Date, make available for the account of its Applicable Lending Office to the Agent at the
Agent’s Account, in same day funds, in the case of such Assuming Lender, an amount equal to such
Assuming Lender’s Ratable Share of the Borrowings then outstanding (calculated based on its
Revolving Credit Commitment as a percentage of the aggregate Revolving Credit Commitments
outstanding after giving effect to the relevant Commitment Increase) and, in the case of such
Increasing Lender, an amount equal to the excess of (i) such Increasing Lender’s Ratable Share of
the Borrowings then outstanding (calculated based on its Revolving Credit Commitment as a
percentage of the aggregate Revolving Credit Commitments outstanding after giving effect to the
relevant Commitment Increase) over (ii) such Increasing Lender’s Ratable Share of the Borrowings
then outstanding (calculated based on its Revolving Credit Commitment (without giving effect to the
relevant Commitment Increase) as a percentage of the aggregate Revolving Credit Commitments
(without giving effect to the relevant Commitment Increase). After the Agent’s receipt of such
funds from each such Increasing Lender and each such Assuming Lender, the Agent will promptly
thereafter cause to be distributed like funds to the other Lenders for the account of their
respective Applicable Lending Offices in an amount to each other Lender such that the aggregate
amount of the outstanding Advances owing to each Lender after giving effect to such distribution
equals such Lender’s Ratable Share of the Borrowings then outstanding (calculated based on its
Revolving Credit Commitment as a percentage of the aggregate Revolving Credit Commitments
outstanding after giving effect to the relevant Commitment Increase).

Section 2.19 Affected Lenders. Notwithstanding any provision of this Agreement to the contrary, if any Lender becomes an
Affected Lender, then the following provisions shall apply for so long as such Lender is an
Affected Lender:

(a) fees shall cease to accrue on the Unused Commitment of such Affected Lender pursuant to
Section 2.04(a);

(b) the Revolving Credit Commitment and Advances of such Affected Lender shall not be included
in determining whether the Required Lenders have taken or may take any action hereunder (including
any consent to any amendment or waiver pursuant to Section 8.01), other than any waiver, amendment
or modification requiring the consent of all Lenders or of each Lender affected;

(c) if there shall be any Available Amount under any outstanding Letter of Credit during any
time a Lender is an Affected Lender, then:

 

44

 

(i) all or any part of the Available Amount of all such Letters of Credit shall be
reallocated among the non-Affected Lenders in accordance with their respective Ratable
Shares (disregarding any Affected Lender’s Revolving Credit Commitment) but only to the
extent that with respect to each non-Affected Lender the sum of (A) the aggregate principal
amount of all Advances made by such non-Affected Lender (in its capacity as a Lender) and
outstanding at such time plus (B) such non-Affected Lender’s Ratable Share (after giving
effect to the reallocation contemplated in this Section 2.19(c)(i)) of the outstanding L/C
Obligations, does not exceed such non-Affected Lender’s Revolving Credit Commitment;

(ii) if the Ratable Share of the Available Amount of outstanding Letters of Credit of
the non-Affected Lenders is reallocated pursuant to Section 2.19(c), then the fees payable
to the Lenders pursuant to Section 2.04(a) and Section 2.04(b) shall be adjusted in
accordance with such non-Affected Lenders’ Ratable Shares; and

(iii) if the Affected Lender’s Ratable Share (the “Affected Lender Share”) of
the Available Amount of all outstanding Letters of Credit is not reallocated pursuant to
Section 2.19(c), then, without prejudice to any rights or remedies of any Issuing Bank or
any Lender hereunder, the fee payable under Section 2.04(b) with respect to such Affected
Lender Share shall be payable to the Issuing Bank until such Affected Lender Share is
reallocated;

(d) to the extent the Agent receives any payments or other amounts for the account of an
Affected Lender under this Agreement, such Affected Lender shall be deemed to have requested that
the Agent use such payment or other amount to fulfill such Affected Lender’s previously unsatisfied
obligations to fund an Advance under Section 2.03(c) or L/C Advance or any other unfunded payment
obligation of such Affected Lender under this Agreement; and

(e) for the avoidance of doubt, the Borrower, each Issuing Bank, the Agent and each other
Lender shall retain and reserve its other rights and remedies respecting each Affected Lender.

In the event that the Agent, the Borrower and the Issuing Banks each agrees that an Affected
Lender has adequately remedied all matters that caused such Lender to be an Affected Lender, then
the Ratable Shares of the Lenders shall be readjusted to reflect the inclusion of such Lender’s
Revolving Credit Commitment and on such date such Lender shall purchase at par such of the Advances
of the other Lenders as the Agent shall determine may be necessary in order for such Lender to hold
such Advances in accordance with its Ratable Share. In addition, at such time as the Affected
Lender is replaced by another Lender pursuant to Section 2.20, the Ratable Shares of the Lenders
will be readjusted to reflect the inclusion of the replacing Lender’s Commitment in accordance with
Section 2.20. In either such case, this Section 2.19 will no longer apply.

Section 2.20 Replacement of Lenders. If any Lender requests compensation under Section 2.11, or if the Borrower is required to
pay any additional amount to any Lender or any Governmental Authority for the account of any Lender
pursuant to Section 2.14, or if any Lender is an Affected Lender, then the Borrower may, at its
sole expense and effort, upon notice to such

 

45

 

Lender and the Agent, require such Lender to assign
and delegate, without recourse (in accordance with and subject to the restrictions contained in,
and consents required by, Section 8.07), all of its interests, rights and obligations under this
Agreement and the related Loan Documents to one or more assignees that shall assume such
obligations (which any such assignee may be another Lender, if a Lender accepts such assignment),
provided that:

(a) the Borrower shall have paid to the Agent the assignment fee specified in Section 8.07(b);

(b) such Lender shall have received payment of an amount equal to the outstanding principal of
its Advances and L/C Advances, accrued interest thereon, accrued fees and all other amounts payable
to it hereunder and under the other Loan Documents (including any amounts under Section 8.04(e))
from the assignee (to the extent of such outstanding principal and accrued interest and fees) or
the Borrower (in the case of all other amounts);

(c) in the case of any such assignment resulting from a claim for compensation under Section
2.11 or payments required to be made pursuant to Section 2.14, such assignment will result in a
reduction in such compensation or payments thereafter; and

(d) such assignment does not conflict with applicable Laws.

A Lender shall not be required to make any such assignment or delegation if, prior thereto, as
a result of a waiver by such Lender or otherwise, the circumstances entitling the Borrower to
require such assignment and delegation cease to apply.

provided, however, that if the 2007 Order is superseded or modified by any
Subsequent Order, the Borrower may, in consultation with the Lenders, revise the Notices of
Borrowing or request for issuance to the extent necessary to take into account any applicable

satisfactory to each Lender in its sole discretion) delivered prior to the execution and delivery

together as a whole with all such written information so furnished, contains an untrue statement of
a material fact or omits to state a material fact necessary in order to make the statements
therein, in the light of the circumstances under which they were made,

 

52

 

not misleading, except as
would not reasonably be expected to result in a Material Adverse Effect; provided that with respect
to any projected financial information, forecasts, estimates or forward-looking information, the
Borrower represents only that such information and materials have been prepared in good faith on
the basis of assumptions believed to be reasonable at the time of preparation of such forecasts,
and no representation or warranty is made as to the actual attainability of any such projections,
forecasts, estimates or forward-looking information.

the Borrower shall fail to perform or observe any other term, covenant or agreement contained in

Agreement; or (ii) any event of default shall exist under any agreement or instrument relating to

(e) The Borrower or any of its Material Subsidiaries shall fail to pay any principal of or
premium or interest in respect of any operating lease in respect of which the payment obligations

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

$35,000,000 in the aggregate shall be rendered against the Borrower or any Material

 

59

 

Subsidiary and
such judgments or orders shall continue unsatisfied or unstayed for a period of 45 days; or

(h) (i) any “person” or “group” (as such terms are used in Sections 13(d) and 14(d) of the

the expiration of any applicable grace period, any installment payment with respect to its
withdrawal liability under Section 4201 of ERISA under a Multiemployer Plan in an aggregate amount
in excess of $35,000,000;

then, and in any such event, the Agent shall at the request, or may with the consent, of the
Required Lenders, by notice to the Borrower, (i) declare the obligation of each Lender to make
Advances (other than L/C Advances) and of the Issuing Banks to issue Letters of Credit to be
terminated, whereupon the same shall forthwith terminate, (ii) declare the Advances, all interest
thereon and all other amounts payable under this Agreement to be forthwith due and payable,
whereupon the Advances, 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; 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 of the United States, (A) the obligation of each Lender to make Advances (other than L/C
Advances) and of the Issuing Banks to issue Letters of Credit shall automatically be terminated and
(B) the Advances, 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 (iii) exercise all rights and remedies available to it under
this Agreement, the other Loan Documents and applicable Law.

Section 6.02 Actions in Respect of Letters of Credit upon Default. If any Event of Default shall have occurred and be continuing, the Agent may with the
consent, or shall at the request, of the Required Lenders, irrespective of whether it is taking any
of the actions described in Section 6.01 or otherwise, (a) make demand upon the Borrower to, and
forthwith upon such

 

60

 

demand the Borrower will Cash Collateralize the aggregate Available Amount of
all Letters of Credit then outstanding (whether or not any beneficiary under any Letter of Credit
shall have drawn or be entitled at such time to draw thereunder) or (b) make such other
arrangements in respect of the outstanding Letters of Credit as shall be acceptable to the Required
Lenders, 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 of the United States, the
Borrower will Cash Collateralize the aggregate Available Amount of all Letters of Credit then
outstanding, without presentment, demand, protest or any notice of any kind, all of which are
hereby expressly waived by the Borrower. If at any time the Agent determines that any funds held
in the L/C Cash Deposit Account are subject to any right or interest of any Person other than the
Agent, the Issuing Banks and the Lenders or that the total amount of such funds is less than the
aggregate Available Amount of all Letters of Credit, the Borrower will, forthwith upon demand by
the Agent, pay to the Agent, as additional funds to be deposited and held in the L/C Cash Deposit
Account, an amount equal to the excess of (a) such aggregate Available Amount over (b) the total
amount of funds, if any, then held in the L/C Cash Deposit Account that are free and clear of any
such right and interest. Upon the drawing of any Letter of Credit, to the extent funds are on
deposit in the L/C Cash Deposit Account, such funds shall be applied to reimburse the Issuing Banks
to the extent permitted by applicable Law, or each Lender to the extent such Lender has funded an
Advance in respect of such Letter of Credit. The Borrower hereby grants to the Agent, for the
benefit of the Issuing Banks and the Lenders, a Lien upon and
security interest in the L/C Cash Deposit Account and all amounts held therein from time to
time as security for the L/C Obligations, and for application to the Borrower’s reimbursement
obligations as and when the same shall arise. The Agent shall have exclusive dominion and control,
including the exclusive right of withdrawal, over such account. After all such Letters of Credit
shall have expired or been fully drawn upon and all other obligations of the Borrower hereunder and
under the other Loan Documents shall have been paid in full, the balance, if any, in such L/C Cash
Deposit Account shall be promptly returned to the Borrower.

ARTICLE VII

THE AGENT

Section 7.01 Appointment and Authority. Each of the Lenders (for purposes of this Article, references to the Lenders shall also
mean the Issuing Banks) hereby irrevocably appoints Wells Fargo to act on its behalf as the Agent
hereunder and under the other Loan Documents and authorizes the Agent to take such actions on its
behalf and to exercise such powers as are delegated to the Agent by the terms hereof or thereof,
together with such actions and powers as are reasonably incidental thereto. Except as set forth in
Section 7.06, the provisions of this Article are solely for the benefit of the Agent and the
Lenders, and neither the Borrower nor any of its Affiliates shall have rights as a third party
beneficiary of any of such provisions.

Section 7.02 Rights as a Lender. The Person serving as the Agent hereunder shall have the same rights and powers in its
capacity as a Lender as any other Lender and may exercise the same as though it were not the Agent
and the term “Lender” or “Lenders” shall, unless otherwise expressly indicated or unless the
context otherwise requires, include the Person serving as the Agent hereunder in its individual
capacity. Such Person and its Affiliates may accept deposits

 

61

 

from, lend money to, act as the
financial advisor or in any other advisory capacity for and generally engage in any kind of
business with the Borrower or any Subsidiary or other Affiliate thereof as if such Person were not
the Agent hereunder and without any duty to account therefor to the Lenders.

Section 7.03 Exculpatory Provisions. The Agent shall not have any duties or obligations except those expressly set forth herein
and in the other Loan Documents. Without limiting the generality of the foregoing, the Agent:

(a) shall not be subject to any fiduciary or other implied duties, regardless of whether a
Default has occurred and is continuing;

(b) shall not have any duty to take any discretionary action or exercise any discretionary
powers, except discretionary rights and powers expressly contemplated hereby or by the other Loan
Documents that the Agent is required to exercise as directed in writing by the Required Lenders (or
such other number or percentage of the Lenders as shall be expressly
provided for herein), provided that the Agent shall not be required to take any action
that, in its opinion or the opinion of its counsel, may expose the Agent to liability or that is
contrary to any Loan Document or applicable Law; and

(c) shall not, except as expressly set forth herein and in the other Loan Documents, have any
duty to disclose, and shall not be liable for the failure to disclose, any information relating to
the Borrower or any of its Affiliates that is communicated to or obtained by the Person serving as
the Agent or any of its Affiliates in any capacity.

The Agent shall not be liable for any action taken or not taken by it (i) with the consent or
at the request of the Required Lenders (or such other number or percentage of the Lenders as shall
be necessary, or as the Agent shall believe in good faith shall be necessary, under the
circumstances as provided in Section 6.01 and 8.01) or (ii) in the absence of its own gross
negligence or willful misconduct. The Agent shall be deemed not to have knowledge of any Default
unless and until notice describing such Default is given to the Agent by the Borrower or a Lender.

The 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 or any other
Loan Document, (ii) the contents of any certificate, report or other document delivered hereunder
or thereunder or in connection herewith or therewith, (iii) the performance or observance of any of
the covenants, agreements or other terms or conditions set forth herein or therein or the
occurrence of any Default, (iv) the validity, enforceability, effectiveness or genuineness of this
Agreement, any other Loan Document or any other agreement, instrument or document or (v) the
satisfaction of any condition set forth in Article III or elsewhere herein, other than to confirm
receipt of items expressly required to be delivered to the Agent.

Section 7.04 Reliance by Agent. The 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
(including any electronic message, internet or intranet website posting or other distribution)
believed by it to be genuine and to have been signed, sent

 

62

 

or otherwise authenticated by the proper
Person. The Agent also may rely upon any statement made to it orally or by telephone and believed
by it to have been made by the proper Person, and shall not incur any liability for relying
thereon. In determining compliance with any condition hereunder to the making of any Advance, or
the issuance of a Letter of Credit, that by its terms must be fulfilled to the satisfaction of a
Lender or an Issuing Bank, the Agent may presume that such condition is satisfactory to such Lender
or such Issuing Bank unless the Agent shall have received notice to the contrary from such Lender
or such Issuing Bank prior to the making of such Advance or the issuance of such Letter of Credit.
The 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 good faith in accordance with the advice of any such counsel, accountants or
experts.

Section 7.05 Delegation of Duties. The Agent may perform any and all of its duties and exercise its rights and powers
hereunder or under any other Loan Document by or through any one or more sub-agents appointed by
the Agent. The Agent and any such sub-agent may perform any and all of its duties and exercise its
rights and powers by or through their respective Related Parties. The exculpatory provisions of
this Article shall apply to any such sub-agent and to the Related Parties of the 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 Agent.

Section 7.06 Resignation of Agent. The Agent may at any time give notice of its resignation to the Lenders and the Borrower.
Upon receipt of any such notice of resignation, the Required Lenders shall have the right, with the
consent of the Borrower so long as no Event of Default has occurred and is continuing, to appoint a
successor, which shall be a bank with an office in the United States, or an Affiliate of any such
bank with an office in the United States. If no such successor shall have been so appointed by the
Required Lenders and shall have accepted such appointment within 45 days after the retiring Agent
gives notice of its resignation, then the retiring Agent may, on behalf of the Lenders, appoint a
successor Agent meeting the qualifications set forth above; provided that if the Agent
shall notify the Borrower and the Lenders that no qualifying Person has accepted such appointment,
then such resignation shall nonetheless become effective in accordance with such notice and (1) the
retiring Agent shall be discharged from its duties and obligations hereunder and under the other
Loan Documents (except that in the case of any collateral security held by the Agent on behalf of
the Lenders under any of the Loan Documents, the retiring Agent shall continue to hold such
collateral security until such time as a successor Agent is appointed) and (2) all payments,
communications and determinations provided to be made by, to or through the Agent shall instead be
made by or to each Lender directly, until such time as the Required Lenders appoint a successor
Agent as provided for above in this Section. Upon the acceptance of a successor’s appointment as
Agent hereunder, such successor shall succeed to and become vested with all of the rights, powers,
privileges and duties of the retiring (or retired) Agent, and the retiring Agent shall be
discharged from all of its duties and obligations hereunder or under the other Loan Documents (if
not already discharged therefrom as provided above in this Section). The fees payable by the
Borrower to a successor Agent shall be as agreed between the Borrower and such successor. After
the retiring Agent’s resignation hereunder and under the other Loan Documents, the provisions of
this Article and Section 8.04 shall continue in effect for the benefit of such retiring

 

63

 

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 the retiring Agent was acting as Agent.

Section 7.07 Non-Reliance on Agent and Other Lenders. Each Lender acknowledges that it has, independently and without reliance upon the Agent or
any other Lender or any of their Related Parties and based on such documents and information as it
has deemed appropriate, made its own credit analysis and decision to enter into this Agreement.
Each Lender also acknowledges that it will, independently and without reliance upon the Agent or
any other Lender or any of their Related Parties 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.

Section 7.08 No Other Duties, Etc. Anything herein to the contrary notwithstanding, none of the Arrangers, Syndication Agent,
Documentation Agent or other agents listed on the cover page hereof shall have any powers, duties
or responsibilities under this Agreement or any of the other Loan Documents, except in its
capacity, as applicable, as the Agent or a Lender hereunder.

Section 7.09 Issuing Banks. Each Issuing Bank shall act on behalf of the Lenders with respect to any Letters of Credit
issued by it and the documents associated therewith, and each Issuing Bank shall have all of the
benefits and immunities provided in this Article VII (other than Section 7.02) to the same extent
as such provisions apply to the Agent.

ARTICLE VIII

MISCELLANEOUS

Section 8.01 Amendments, Etc. No amendment or waiver of any provision of this Agreement or any other Loan Document, nor
consent to any departure by the Borrower therefrom, shall in any event be effective unless the same
shall be in writing and signed by the Required Lenders, and then such waiver or consent shall be
effective only in the specific instance and for the specific purpose for which given;
provided, however, that no amendment, waiver or consent shall

(a) unless agreed to by each Lender directly affected thereby, (i) reduce or forgive the
principal amount of any Advance or the Borrower’s obligations to reimburse any drawing on a Letter
of Credit, reduce the rate of or forgive any interest thereon (provided that only the
consent of the Required Lenders shall be required to waive the applicability of any post-default
increase in interest rates), or reduce or forgive any fees hereunder (other than fees payable to
the Agent, the Arrangers or any Issuing Bank for their own respective accounts), (ii) extend the
final scheduled maturity date or any other scheduled date for the payment of any principal of or
interest on any Advance, extend the time of payment of any obligation of the Borrower to reimburse
any drawing on any Letter of Credit or any interest thereon, extend the expiry date of any Letter
of Credit beyond the fifth Business Day prior to the Termination Date, or extend the time of
payment of any fees hereunder (other than fees payable to the Agent, the Arrangers or any Issuing
Bank for their own respective accounts), or (iii) increase any Revolving Credit

 

64

 

Commitment of any
such Lender over the amount thereof in effect or extend the maturity thereof (it being understood
that a waiver of any condition precedent set forth in Section 3.02 or of any Default, if agreed to
by the Required Lenders or all Lenders (as may be required hereunder with respect to such waiver),
shall not constitute such an increase);

(b) unless agreed to by all of the Lenders, (i) reduce the percentage of the aggregate
Revolving Credit Commitments or of the aggregate unpaid principal amount of the Advances, or the
number or percentage of Lenders, that shall be required for the Lenders or any of them to take or
approve, or direct the Agent to take, any action hereunder or under any other Loan Document
(including as set forth in the definition of “Required Lenders”), (ii) change any other provision
of this Agreement or any of the other Loan Documents requiring, by its terms, the consent or
approval of all the Lenders for such amendment, modification, waiver, discharge, termination or
consent, or (iii) change or waive any provision of Section 2.15, any other provision of this
Agreement or any other Loan Document requiring pro rata treatment of any Lenders, or this Section
8.01 or Section 2.19(b); and

(c) unless agreed to by the Issuing Banks or the Agent in addition to the Lenders required as
provided hereinabove to take such action, affect the respective rights or obligations of the
Issuing Banks or the Agent, as applicable, hereunder or under any of the other Loan Documents.

Section 8.02 Notices, Etc.

(a) All notices and other communications provided for hereunder shall be either (x) in writing
(including facsimile communication) and mailed, faxed or delivered or (y) as and to the extent set
forth in Sections 8.02(b) and (c) and in the proviso to this Section 8.02(a), if to the Borrower,
at the address specified on Schedule 8.02; if to any Lender, at its Domestic Lending
Office; if to the Agent, at the address specified on Schedule 8.02; and if to any Issuing
Bank, at the address specified on Schedule 8.02 or, as to the Borrower or the Agent, at
such other address as shall be designated by such party in a written notice to the other parties
and, as to each other party, at such other address as shall be designated by such party in a
written notice to the Borrower and the Agent. All such notices and communications shall, when
mailed or faxed, be effective when deposited in the mails or faxed, respectively, except that
notices and communications to the Agent pursuant to Article II, III or VII shall not be effective
until received by the Agent. Delivery by facsimile of an executed counterpart of any amendment or
waiver of any provision of this Agreement or the Notes or of any Exhibit hereto to be executed and
delivered hereunder shall be effective as delivery of a manually executed counterpart thereof.
Notices delivered through electronic communications to the extent provided in subsection (b) below,
shall be effective as provided in such subsection (b). Upon request of the Borrower, the Agent
will provide to the Borrower (i) copies of each Administrative Questionnaire or (ii) the address of
each Lender.

(b) Notices and other communications to the Lenders, the Agent and the Issuing Banks hereunder
may be delivered or furnished by electronic communication (including e-mail and Internet or
intranet websites) pursuant to procedures approved by the Agent and agreed to by the Borrower,
provided that the foregoing shall not apply to notices to any Lender or the Issuing Banks
pursuant to Article II if such Lender or the Issuing Banks, as applicable, has notified the

 

65

 

Agent and the Borrower that it is incapable of receiving notices under such Article by electronic
communication. The Agent or the Borrower may, in its discretion, agree to accept notices and other
communications to it hereunder by electronic communications pursuant to procedures approved by it,
provided that approval of such procedures may be limited to particular notices or
communications. Unless the Agent and the Borrower otherwise agree, (i) notices and other
communications sent to an e-mail address shall be deemed received upon the sender’s receipt of
an acknowledgement from the intended recipient (such as by the “return receipt requested” function,
as available, return e-mail or other written acknowledgement), provided that if such notice
or other communication is not sent during the normal business hours of the recipient, such notice
or communication shall be deemed to have been sent at the opening of business on the next business
day for the recipient, and (ii) notices or communications posted to an Internet or intranet website
shall be deemed received upon the deemed receipt by the intended recipient at its e-mail address as
described in the foregoing clause (i) of notification that such notice or communication is
available and identifying the website address therefor.

(c) The Borrower agrees that the Agent may make materials delivered to the Agent pursuant to
Sections 5.01(h)(i), (ii) and (iv), as well as any other written information, documents,
instruments and other material relating to the Borrower or any of its Subsidiaries and relating to
this Agreement, the Notes or the transactions contemplated hereby, or any other materials or
matters relating to this Agreement, the Notes or any of the transactions contemplated hereby
(collectively, the “Communications”) available to the Lenders by posting such notices on
Intralinks or a substantially similar electronic system (the “Platform”). The Borrower
acknowledges that (i) the distribution of material through an electronic medium is not necessarily
secure and that there are confidentiality and other risks associated with such distribution, (ii)
the Platform is provided “as is” and “as available” and (iii) neither the Agent nor any of its
Affiliates warrants the accuracy, adequacy or completeness of the Communications or the Platform
and each expressly disclaims liability for errors or omissions in the Communications or the
Platform. 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 the Agent or any of its Affiliates
in connection with the Platform.

(d) Each Lender agrees that notice to it (as provided in the next sentence) (a
“Notice”) specifying that any Communications have been posted to the Platform shall
constitute effective delivery of such information, documents or other materials to such Lender for
purposes of this Agreement; provided that if requested by any Lender the Agent shall
deliver a copy of the Communications to such Lender by e-mail, facsimile or mail. Each Lender
agrees (i) to notify the Agent in writing of such Lender’s e-mail address to which a Notice may be
sent by electronic transmission (including by electronic communication) on or before the date such
Lender becomes a party to this Agreement (and from time to time thereafter to ensure that the Agent
has on record an effective e-mail address for such Lender) and (ii) that any Notice may be sent to
such e-mail address.

(e) The Borrower hereby acknowledges that certain of the Lenders may be “public-side” Lenders
(i.e., Lenders that do not wish to receive material non-public information with respect to the
Borrower or its securities) (each, a “Public Lender”). The Borrower hereby agrees that (w)
all Communications that are to be made available to Public Lenders shall be clearly and

 

66

 

conspicuously marked “PUBLIC” which shall mean that the word “PUBLIC” shall appear prominently on
the first page thereof; (x) by marking Communications “PUBLIC,” the Borrower shall be deemed to
have authorized the Agent, the Arranger and the Lenders to treat such Communications as not
containing any material non-public information with respect to the Borrower or its securities for
purposes of United States federal and state securities laws; (y) all
Communications marked “PUBLIC” are permitted to be made available through a portion of the
Platform designated as “Public Investor;” and (z) the Agent and the Arranger shall be entitled to
treat any Communications that are not marked “PUBLIC” as being suitable only for posting on a
portion of the Platform not marked as “Public Investor.” Notwithstanding the foregoing, the
Borrower shall be under no obligation to mark any Communications “PUBLIC.” Notwithstanding anything
to the contrary herein, the Borrower need not provide to any Public Lender any information, notice,
or other document hereunder that is not public information, including without limitation, the
Notice of Borrowing and any notice of Default.

Section 8.03 No Waiver; Cumulative Remedies; Enforcement. No failure by any Lender, any Issuing Bank or the Agent to exercise, and no delay by any
such Person in exercising, any right, remedy, power or privilege hereunder shall operate as a
waiver thereof; nor shall any single or partial exercise of any right, remedy, power or privilege
hereunder preclude any other or further exercise thereof or the exercise of any other right,
remedy, power or privilege. The rights, remedies, powers and privileges herein provided are
cumulative and not exclusive of any rights, remedies, powers and privileges provided by Law.

Notwithstanding anything to the contrary contained herein or in any other Loan Document, the
authority to enforce rights and remedies hereunder and under the other Loan Documents against the
Borrower shall be vested exclusively in, and all actions and proceedings at Law in connection with
such enforcement shall be instituted and maintained exclusively by, the Agent in accordance with
Article VI for the benefit of all the Lenders and the Issuing Banks; provided,
however, that the foregoing shall not prohibit (a) the Agent from exercising on its own
behalf the rights and remedies that inure to its benefit (solely in its capacity as Agent)
hereunder and under the other Loan Documents, (b) any Issuing Bank from exercising the rights and
remedies that inure to its benefit (solely in its capacity as an Issuing Bank) hereunder and under
the other Loan Documents, (c) any Lender from exercising setoff rights in accordance with Section
8.05 (subject to the terms of Section 2.15), or (d) any Lender from filing proofs of claim or
appearing and filing pleadings on its own behalf during the pendency of a proceeding relative to
the Borrower under any Debtor Relief Law; and provided, further, that if at any
time there is no Person acting as Agent hereunder and under the other Loan Documents, then (i) the
Required Lenders shall have the rights otherwise ascribed to the Agent pursuant to Article VI and
(ii) in addition to the matters set forth in clauses (b), (c) and (d) of the preceding proviso and
subject to Section 2.15, any Lender may, with the consent of the Required Lenders, enforce any
rights and remedies available to it and as authorized by the Required Lenders.

Section 8.04 Costs and Expenses; Indemnity; Damage Waiver.

(a) The Borrower agrees to pay on demand all costs and expenses of the Agent in connection
with the administration, modification and amendment of this Agreement, the Notes and the other Loan
Documents to be delivered hereunder, including, without limitation, the reasonable fees and
expenses of counsel for the Agent with respect thereto and with respect to

 

67

 

advising the Agent as to
its rights and responsibilities under this Agreement. The Borrower further agrees to pay on demand
all costs and expenses of the Agent and the Lenders, if any (including, without limitation,
reasonable counsel fees and expenses), in connection with the enforcement (whether through
negotiations, legal proceedings or otherwise) of this Agreement,
the Notes and the other Loan Documents to be delivered hereunder, including, without
limitation, reasonable fees and expenses of counsel for the Agent and each Lender in connection
with the enforcement of rights under this Section 8.04(a).

(b) The Borrower agrees to indemnify and hold harmless the Agent (and any sub-agent thereof),
each Lender, and each Related Party of any of the foregoing (each, an “Indemnified Party”)
from and against any and all claims, damages, losses, liabilities and expenses (including, without
limitation, reasonable fees and expenses of counsel) incurred by or asserted or awarded against any
Indemnified Party, in each case arising out of or in connection with or by reason of (including,
without limitation, in connection with any investigation, litigation or proceeding or preparation
of a defense in connection therewith, whether based on contract, tort or any other theory,) (i) the
Notes, this Agreement, any of the transactions contemplated herein or the actual or proposed use of
the proceeds of any Advance or Letter of Credit (including any refusal by any Issuing Bank to honor
a demand for payment under a Letter of Credit if the documents presented in connection with such
demand do not strictly comply with the terms of such Letter of Credit), or (ii) the actual or
alleged presence of Hazardous Materials on any property of the Borrower or any of its Subsidiaries
or any Environmental Action relating in any way to the Borrower or any of its Subsidiaries,
provided that such indemnity shall not, as to any Indemnified Party, be available to the
extent (a) such fees and expenses are expressly stated in this Agreement to be payable by the
Indemnified Party, included expenses payable under Section 2.14, Section 5.01(e) and Section
8.07(b) or (b) such claim, damage, loss, liability or expense is found in a final, non-appealable
judgment by a court of competent jurisdiction to have resulted from such Indemnified Party’s gross
negligence, willful misconduct or material breach of its obligations under this Agreement, in which
case any fees and expenses previously paid or advanced by the Borrower to such Indemnified Party in
respect of such indemnified obligation will be returned by such Indemnified Party. In the case of
an investigation, litigation or other proceeding to which the indemnity in this Section 8.04(b)
applies, such indemnity shall be effective whether or not such investigation, litigation or
proceeding is brought by the Borrower, its directors, equityholders or creditors or an Indemnified
Party or any other Person, whether or not any Indemnified Party is otherwise a party thereto, and
whether or not the transactions contemplated hereby are consummated, provided that if the
Borrower and such Indemnified Party are adverse parties in any such litigation or proceeding, and
the Borrower prevails in a final, non-appealable judgment by a court of competent jurisdiction, any
fees or expenses previously paid or advanced by the Borrower to such Indemnified Party pursuant to
this Section 8.04(b) will be returned by such Indemnified Party.

(c) To the extent that the Borrower for any reason fails to indefeasibly pay any amount
required under subsection (a) or (b) of this Section to be paid by it to the Agent (or any
sub-agent thereof), any Issuing Bank or any Related Party of any of the foregoing (and without
limiting its obligation to do so), each Lender severally agrees to pay to the Agent (or any such
sub-agent), such Issuing Bank or such Related Party, as the case may be, such Lender’s Ratable
Share (determined as of the time that the applicable unreimbursed expense or indemnity payment is
sought) of such unpaid amount, provided that the unreimbursed expense or indemnified loss,

 

68

 

claim, damage, liability or related expense, as the case may be, was incurred by or asserted
against the Agent (or any such sub-agent) or such Issuing Bank in its capacity as such, or against
any Related Party of any of the foregoing acting for the Agent (or any such sub-agent) or such
Issuing Bank in connection with such capacity.

(d) Each party hereto also agrees not to assert any claim for special, indirect, consequential
or punitive damages against the other parties hereto, or any Related Person any party hereto, on
any theory of liability, arising out of or otherwise relating to the Notes, this Agreement, any of
the transactions contemplated herein or the actual or proposed use of the proceeds of the Advances
or the Letters of Credit. No Indemnified Party shall be liable for any damages arising from the
use by unintended recipients of any information or other materials distributed by it through
telecommunications, electronic or other information transmission systems (including Intralinks,
SyndTrak or similar systems) in connection with this Agreement or the other Loan Documents,
provided that such indemnity shall not, as to any Indemnified Party, be available to the
extent such damages are found in a final, non-appealable judgment by a court of competent
jurisdiction to have resulted from such Indemnified Party’s gross negligence or willful misconduct.

(e) If any payment of principal of, or Conversion of, any Eurodollar Rate Advance is made by
the Borrower to or for the account of a Lender other than on the last day of the Interest Period
for such Advance, as a result of a payment or Conversion pursuant to Section 2.08(d) or (e), 2.10
or 2.12, acceleration of the maturity of the Advances pursuant to Section 6.01 or for any other
reason, or by an Eligible Assignee to a Lender other than on the last day of the Interest Period
for such Advance upon an assignment of rights and obligations under this Agreement pursuant to
Section 8.07 as a result of a demand by the Borrower pursuant to Section 8.07(a), the Borrower
shall, upon demand by such Lender (with a copy of such demand to the Agent), pay to the Agent for
the account of such Lender any amounts required to compensate such Lender for any additional
losses, costs or expenses that it may reasonably incur as a result of such payment or Conversion,
including, without limitation, any loss (excluding loss of anticipated profits), cost or expense
incurred by reason of the liquidation or reemployment of deposits or other funds acquired by any
Lender to fund or maintain such Advance.

(f) Without prejudice to the survival of any other agreement of the Borrower hereunder, the
agreements and obligations of the Borrower contained in Sections 2.11, 2.14 and 8.04 shall survive
the payment in full of principal, interest and all other amounts payable hereunder and under the
Notes.

Section 8.05 Right of Set-off. 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 6.01 to authorize the
Agent to declare the Advances due and payable pursuant to the provisions of Section 6.01, each
Lender, each Issuing Bank and each of their respective Affiliates is hereby authorized at any time
and from time to time, to the fullest extent permitted by Law, to set off and apply any and all
deposits (general or special, time or demand, provisional or final) at any time held and other
indebtedness at any time owing by such Lender, such Issuing Bank or any such Affiliate 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 or any other Loan Document to such Lender or Issuing
Bank, whether or not such Lender or Issuing Bank

 

69

 

shall have made any demand under this Agreement or
such Note and although such obligations may be contingent or unmatured or are owed to a branch or
office of such Lender or such Issuing Bank different from the branch or office holding such deposit
or obligated on such indebtedness. Each Lender and each Issuing
Bank agrees promptly to notify the Borrower after any such set-off and application,
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 each Issuing Bank under this Section are in
addition to other rights and remedies (including, without limitation, other rights of set-off) that
such Lender may have.

Section 8.06 Binding Effect. Except as provided in Section 3.01, this Agreement shall become effective when it shall
have been executed by the Borrower and the Agent and when the Agent shall have been notified by
each Initial Lender that such Initial Lender has executed it and thereafter shall be binding upon
and inure to the benefit of the Borrower, the Agent 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 8.07 Successors and Assigns.

(a) The provisions of this Agreement shall be binding upon and inure to the benefit of the
parties hereto and their respective successors and assigns permitted hereby, except that the
Borrower may not assign or otherwise transfer any of its rights or obligations hereunder without
the prior written consent of the Agent and each Lender (and any purported assignment or transfer
without such consent shall be null and void) and no Lender may assign or otherwise transfer any of
its rights or obligations hereunder except (i) to an assignee in accordance with the provisions of
subsection (b) of this Section, (ii) by way of participation in accordance with the provisions of
subsection (d) of this Section, or (iii) by way of pledge or assignment of a security interest
subject to the restrictions of subsection (f) of this Section. Nothing in this Agreement,
expressed or implied, shall be construed to confer upon any Person (other than the parties hereto,
their respective successors and assigns permitted hereby, Participants to the extent provided in
subsection (d) of this Section and, to the extent expressly contemplated hereby, the Related
Parties of each of the Agent, the Issuing Banks and the Lenders) any legal or equitable right,
remedy or claim under or by reason of this Agreement.

(b) Any Lender may at any time assign to one or more assignees all or a portion of its rights
and obligations under this Agreement (including all or a portion of its Revolving Credit Commitment
and the Advances (including for purposes of this subsection (b), participations in L/C Obligations)
at the time owing to it); provided that any such assignment shall be subject to the
following conditions:

(i) Minimum Amounts.

(A) in the case of an assignment of the entire remaining amount of the
assigning Lender’s Revolving Credit Commitment and the Advances at the time owing to
it or in the case of an assignment to a Lender, no minimum amount need be assigned;
and

 

70

 

(B) in any case not described in subsection (b)(i)(A) of this Section, the
aggregate amount of the Revolving Credit Commitment (which for this purpose includes
Advances outstanding thereunder) or, if the Revolving Credit Commitment is not then
in effect, the principal outstanding balance of the
Advances of the assigning Lender subject to each such assignment, determined as
of the date the Assignment and Assumption with respect to which such assignment is
delivered to the Agent or, if “Trade Date” is specified in the Assignment and
Assumption, as of the Trade Date, shall not be less than $5,000,000 unless each of
the Agent and, so long as no Event of Default has occurred and is continuing, the
Borrower otherwise consents (each such consent not to be unreasonably withheld or
delayed).

(ii) Proportionate Amounts. Each partial assignment shall be made as an
assignment of a proportionate part of all the assigning Lender’s rights and obligations
under this Agreement with respect to the Advances, L/C Obligations or the Revolving Credit
Commitment assigned, and each such assignment shall be of a constant, and not a varying,
percentage of all rights and obligations under this Agreement;

(iii) Required Consents. No consent shall be required for any assignment
except to the extent required by subsection (b)(i)(B) of this Section and, in addition:

(A) the consent of the Borrower (such consent not to be unreasonably withheld
or delayed) shall be required unless (1) an Event of Default has occurred and is
continuing at the time of such assignment or (2) such assignment is to a Lender, an
Affiliate of a Lender or an Approved Fund;

(B) the consent of the Agent (such consent not to be unreasonably withheld or
delayed) shall be required if such assignment is to a Person that is not a Lender,
an Affiliate of such Lender or an Approved Fund with respect to such Lender;

(C) the consent of each Issuing Bank (such consent not to be unreasonably
withheld or delayed) shall be required for any assignment that increases the
obligation of the assignee to participate in exposure under one or more Letters of
Credit (whether or not then outstanding);.

(iv) Assignment and Assumption. The parties to each assignment shall execute
and deliver to the Agent an Assignment and Assumption, together with a processing and
recordation fee in the amount of $3,500; provided, however, that no such fee
shall be payable in the case of an assignment made at the request of the Borrower to an
existing Lender. The assignee, if it is not a Lender, shall deliver to the Agent an
Administrative Questionnaire.

(v) No Assignment to Borrower. No such assignment shall be made to the
Borrower or any of the Borrower’s Affiliates or Subsidiaries.

(vi) No Assignment to Natural Persons. No such assignment shall be made to a
natural person.

 

71

 

Subject to acceptance and recording thereof by the Agent pursuant to subsection (c) of this
Section and notice thereof to the Borrower, from and after the effective date specified in each
Assignment and Assumption, the assignee thereunder shall be a party to this Agreement
and, to the extent of the interest assigned by such Assignment and Assumption, have the rights
and obligations of a Lender under this Agreement, and the assigning Lender thereunder shall, to the
extent of the interest assigned by such Assignment and Assumption, be released from its obligations
under this Agreement (and, in the case of an Assignment and Assumption covering all of the
assigning Lender’s rights and obligations under this Agreement, such Lender shall cease to be a
party hereto) but shall continue to be entitled to the benefits of Sections 2.11, 2.14 and 8.04
with respect to facts and circumstances occurring prior to the effective date of such assignment.
Upon request, the Borrower (at its expense) shall execute and deliver a Note to the assignee
Lender. Any assignment or transfer by a Lender of rights or obligations under this Agreement that
does not comply with this subsection shall be treated for purposes of this Agreement as a sale by
such Lender of a participation in such rights and obligations in accordance with subsection (d) of
this Section.

(c) Register. The Agent shall maintain at the Agent’s Office a copy of each
Assignment and Assumption delivered to it and a register for the recordation of the names and
addresses of the Lenders, and the Revolving Credit Commitments of, and principal amounts of the
Advances and L/C Obligations owing to, each Lender pursuant to the terms hereof from time to time
(the “Register”). The entries in the Register shall be conclusive, absent manifest error,
and the Borrower, the Agent and the Lenders may treat each Person whose name is recorded in the
Register pursuant to the terms hereof as a Lender hereunder for all purposes of this Agreement,
notwithstanding notice to the contrary. The Register shall be available for inspection by the
Borrower and any Lender, at any reasonable time and from time to time upon reasonable prior notice.

(d) Participations. Any Lender may at any time, without the consent of, or notice to,
the Borrower or the Agent, sell participations to any Person (other than a natural person or the
Borrower or any of the Borrower’s Affiliates or Subsidiaries) (each, a “Participant”) in
all or a portion of such Lender’s rights and/or obligations under this Agreement (including all or
a portion of its Revolving Credit Commitment and/or the Advances (including such Lender’s
participations in L/C Obligations) owing to it); provided that (i) such Lender’s
obligations under this Agreement shall remain unchanged, (ii) such Lender shall remain solely
responsible to the other parties hereto for the performance of such obligations, (iii) the
Borrower, the Agent, the Lenders and the Issuing Banks shall continue to deal solely and directly
with such Lender in connection with such Lender’s rights and obligations under this Agreement and
(iv) no participant under any such participation shall have any right to approve any amendment or
waiver of any provision of this Agreement or any Note, or any consent to any departure by the
Borrower therefrom, except to the extent that such amendment, waiver or consent would reduce the
principal of, or interest on, any Obligations or any fees or other amounts payable hereunder, in
each case to the extent subject to such participation, or postpone any date fixed for any payment
of principal of, or interest on, any Obligations or any fees or other amounts payable hereunder, in
each case to the extent subject to such participation.

Any agreement or instrument pursuant to which a Lender sells such a participation shall
provide that such Lender shall retain the sole right to enforce this Agreement and to approve any

 

72

 

amendment, modification or waiver of any provision of this Agreement; provided that such
agreement or instrument may provide that such Lender will not, without the consent of the
Participant, agree to any amendment, waiver or other modification addressing the matters set
forth in clause (iv) above to the extent subject to such participation. Subject to subsection
(e) of this Section, the Borrower agrees that each Participant shall be entitled to the benefits of
Sections 2.11, 2.14 and 8.04(e) to the same extent as if it were a Lender and had acquired its
interest by assignment pursuant to subsection (b) of this Section. To the extent permitted by Law,
each Participant also shall be entitled to the benefits of Section 8.05 as though it were a Lender,
provided such Participant agrees to be subject to Section 2.15 as though it were a Lender.

(e) Limitations upon Participant Rights. A Participant shall not be entitled to
receive any greater payment under Section 2.11 or 2.14 than the applicable Lender would have been
entitled to receive with respect to the participation sold to such Participant, unless the sale of
the participation to such Participant is made with the Borrower’s prior written consent. A
Participant that would be a Foreign Lender if it were a Lender shall not be entitled to the
benefits of Section 2.14 unless the Borrower is notified of the participation sold to such
Participant and such Participant agrees, for the benefit of the Borrower, to comply with Section
2.14(e) as though it were a Lender.

(f) Certain Pledges. Any Lender may at any time pledge or assign a security interest
in all or any portion of its rights under this Agreement (including under its Note, if any) to
secure obligations of such Lender, including 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.

(g) Resignation as an Issuing Bank after Assignment. Notwithstanding anything to the
contrary contained herein, if at any time any Issuing Bank assigns all of its Revolving Credit
Commitment and Advances pursuant to subsection (b) above, such Issuing Bank may, upon 30 days’
notice to the Borrower and the Lenders, resign as an Issuing Bank. If any Issuing Bank resigns, it
shall retain all the rights, powers, privileges and duties of an Issuing Bank hereunder with
respect to all Letters of Credit outstanding as of the effective date of its resignation as an
Issuing Bank and all L/C Obligations with respect thereto (including the right to require the
Lenders to make Base Rate Advances or fund risk participations in Unreimbursed Amounts pursuant to
Section 2.03(c)).

(h) The words “execution,” “signed,” “signature,” and words of like import in any Assignment
and Assumption shall be deemed to include electronic signatures or the keeping of records in
electronic form, each of which shall be of the same legal effect, validity or enforceability as a
manually executed signature or the use of a paper-based recordkeeping system, as the case may be,
to the extent and as provided for in any applicable Law, including the Federal Electronic
Signatures in Global and National Commerce Act, the New York State Electronic Signatures and
Records Act, or any other similar state Laws based on the Uniform Electronic Transactions Act.

Section 8.08 Confidentiality. Neither the Agent nor any Lender may disclose to any Person any confidential, proprietary
or non-public information of the Borrower furnished to the

 

73

 

Agent or the Lenders by the Borrower
(such information being referred to collectively herein as the “Borrower 
Information”), except that each of the Agent and each of the Lenders may disclose
Borrower Information (i) to its and its affiliates’ employees, officers, directors, agents and
advisors having a need to know in connection with this Agreement (it being understood that the
Persons to whom such disclosure is made will be informed of the confidential nature of such
Borrower Information and instructed to keep such Borrower Information confidential on substantially
the same terms as provided herein), (ii) to the extent requested by any regulatory authority, (iii)
to the extent required by applicable Laws or regulations or by any subpoena or similar legal
process, (iv) to any other party to this Agreement, (v) in connection with the exercise of any
remedies hereunder or any suit, action or proceeding relating to this Agreement or the enforcement
of rights hereunder, (vi) subject to an agreement containing provisions substantially the same as
those of this Section 8.08, to any assignee or participant or prospective assignee or participant,
(vii) to the extent such Borrower Information (A) is or becomes generally available to the public
on a non-confidential basis other than as a result of a breach of this Section 8.08 by the Agent or
such Lender or their Related Parties, or (B) is or becomes available to the Agent or such Lender on
a nonconfidential basis from a source other than the Borrower (provided that the source of such
information was not known by the recipient after inquiry to be bound by a confidentiality agreement
with or other contractual, legal or fiduciary obligation of confidentiality to the Borrower or any
other Person with respect to such information) and (viii) with the consent of the Borrower. The
obligations under this Section 8.08 shall survive for two calendar years after the date of the
termination of this Agreement.

Section 8.09 Governing Law. This Agreement and the Notes shall be governed by, and construed in accordance with, the
Laws of the State of New York (including Sections 5-1401 and 5-1402 of the General Obligations Law
but otherwise without regard to conflict of law principles).

Section 8.10 Counterparts; Integration; Effectiveness. This Agreement may be executed in counterparts (and by different parties hereto in
different counterparts), each of which shall constitute an original, but all of which when taken
together shall constitute a single contract. This Agreement and the other Loan Documents
constitute the entire contract among the parties relating to the subject matter hereof and
supersede any and all previous agreements and understandings, oral or written, relating to the
subject matter hereof. Except as provided in Section 3.01, this Agreement shall become effective
when it shall have been executed by the Agent and when the Agent shall have received counterparts
hereof that, when taken together, bear the signatures of each of the other parties hereto.
Delivery of an executed counterpart of a signature page of this Agreement by telecopy or other
electronic imaging means shall be effective as delivery of a manually executed counterpart of this
Agreement.

Section 8.11 Jurisdiction, Etc.

(a) Each of the parties hereto hereby submits to the non-exclusive jurisdiction of any New
York State court or federal court of the United States of America sitting in New York City, and any
appellate court from any thereof, in any action or proceeding arising out of or relating to this
Agreement or the other Loan Documents, or for recognition or enforcement of any
judgment, and each of the parties hereto hereby agrees that all claims in respect of any such
action or proceeding may be heard and determined in any such New York State court or, to the

 

74

 

extent permitted by Law, in such federal court. Nothing in this Agreement shall affect any right that any
party may otherwise have to bring any action or proceeding relating to this Agreement or the Notes
in the courts of any jurisdiction.

(b) Each of the parties hereto irrevocably and unconditionally waives, to the fullest extent
it may legally and effectively do so, any objection that it may now or hereafter have to the laying
of venue of any suit, action or proceeding arising out of or relating to this Agreement or the
Notes in any New York State or federal court. Each of the parties hereto hereby irrevocably
waives, to the fullest extent permitted by Law, the defense of an inconvenient forum to the
maintenance of such action or proceeding in any such court.

Section 8.12 Payments Set Aside. To the extent that any payment by or on behalf of the Borrower is made to the Agent, any
Issuing Bank or any Lender, or the Agent, any Issuing Bank or any Lender exercises its right of
setoff, and such payment or the proceeds of such setoff or any part thereof is subsequently
invalidated, declared to be fraudulent or preferential, set aside or required (including pursuant
to any settlement entered into by the Agent, such Issuing Bank or such Lender in its discretion) to
be repaid to a trustee, receiver or any other party, in connection with any proceeding under any
Debtor Relief Law or otherwise, then (a) to the extent of such recovery, the obligation or part
thereof originally intended to be satisfied shall be revived and continued in full force and effect
as if such payment had not been made or such setoff had not occurred, and (b) each Lender and each
Issuing Bank severally agrees to pay to the Agent upon demand its applicable share (without
duplication) of any amount so recovered from or repaid by the Agent, plus interest thereon from the
date of such demand to the date such payment is made at a rate per annum equal to the Federal Funds
Rate from time to time in effect. The obligations of the Lenders and the Issuing Banks under
clause (b) of the preceding sentence shall survive the payment in full of the Obligations and the
termination of this Agreement.

Section 8.13 Patriot Act. Each Lender hereby notifies the Borrower that pursuant to the requirements of the USA
Patriot Act (Title III of Pub. L. 107-56 (signed into law October 26, 2001)) (the “Act”),
it is required to obtain, verify and record information that identifies each borrower, guarantor or
grantor (the “Loan Parties”), which information includes the name and address of each Loan
Party and other information that will allow such Lender to identify such Loan Party in accordance
with the Act. The Borrower shall provide, to the extent commercially reasonable, such information
and take such actions as are reasonably requested by the Agent or any Lender in order to assist the
Agent and such Lender in maintaining compliance with the Act.

Section 8.14 Waiver of Jury Trial. EACH OF THE BORROWER, THE AGENT AND THE LENDERS HEREBY IRREVOCABLY WAIVES ALL RIGHT TO
TRIAL BY JURY IN ANY ACTION, PROCEEDING OR COUNTERCLAIM (WHETHER BASED ON CONTRACT, TORT OR
OTHERWISE) ARISING OUT OF OR RELATING TO THIS AGREEMENT, THE NOTES OR ANY OTHER LOAN DOCUMENT
OR THE ACTIONS OF THE BORROWER, THE AGENT OR ANY LENDER IN THE NEGOTIATION, ADMINISTRATION,
PERFORMANCE OR ENFORCEMENT THEREOF.

Section 8.15 No Advisory or Fiduciary Responsibility. In connection with all aspects of each transaction contemplated hereby, the Borrower
acknowledges and agrees that: (i) the credit facilities provided for hereunder and any related
arranging or other services in connection

 

75

 

therewith (including in connection with any amendment,
waiver or other modification hereof or of any other Loan Document) are an arm’s-length commercial
transaction between the Borrower, on the one hand, and the Agent, each of the Lenders and each of
the Arrangers, on the other hand, and the Borrower is capable of evaluating and understanding and
understands and accepts the terms, risks and conditions of the transactions contemplated hereby and
by the other Loan Documents (including any amendment, waiver or other modification hereof or
thereof); (ii) in connection with the process leading to such transaction, each of the Agent, the
Lenders and the Arrangers is and has been acting solely as a principal and is not the financial
advisor, agent or fiduciary, for the Borrower or any of its Affiliates, stockholders, creditors or
employees or any other Person; (iii) neither the Agent nor any Lender or Arranger has assumed or
will assume an advisory, agency or fiduciary responsibility in favor of the Borrower with respect
to any of the transactions contemplated hereby or the process leading thereto, including with
respect to any amendment, waiver or other modification hereof or of any other Loan Document
(irrespective of whether the Agent or any Lender or Arranger has advised or is currently advising
the Borrower or any of its Affiliates on other matters) and neither the Agent nor any Lender or
Arranger has any obligation to the Borrower with respect to the transactions contemplated hereby
except those obligations expressly set forth herein and in the other Loan Documents; (iv) the
Agent, each of the Lenders and the Arrangers and their respective Affiliates may be engaged in a
broad range of transactions that involve interests that differ from those of the Borrower and its
Affiliates, and neither the Agent nor any Lender or Arranger has any obligation to disclose any of
such interests by virtue of any advisory, agency or fiduciary relationship; and (v) the Agent and
each Lender and Arranger have not provided and will not provide any legal, accounting, regulatory
or tax advice with respect to any of the transactions contemplated hereby (including any amendment,
waiver or other modification hereof or of any other Loan Document) and the Borrower has consulted
its own legal, accounting, regulatory and tax advisors to the extent it has deemed appropriate.
The Borrower hereby waives and releases, to the fullest extent permitted by Law, any claims that it
may have against the Agent and each Lender and Arranger with respect to any breach or alleged
breach of agency or fiduciary duty in connection with the Loan Documents.

Section 8.16 Survival of Representations and Warranties. All representations and warranties made hereunder and in any other Loan Document or other
document delivered pursuant hereto or thereto or in connection herewith or therewith shall survive
the execution and delivery hereof and thereof. Such representations and warranties have been or
will be relied upon by the Agent and each Lender, regardless of any investigation made by the Agent
or any Lender or on their behalf, and shall continue in full force and effect as long
as any Advance or any other Obligation hereunder shall remain unpaid or unsatisfied or any
Letter of Credit shall remain outstanding.

Section 8.17 Severability. If any provision of this Agreement or the other Loan Documents is held to be illegal,
invalid or unenforceable, (a) the legality, validity and enforceability of the remaining provisions
of this Agreement and the other Loan Documents shall not be affected or impaired thereby and (b)
the parties shall endeavor in good faith negotiations to replace the illegal, invalid or
unenforceable provisions with valid provisions the economic effect of which comes as close as
possible to that of the illegal, invalid or unenforceable provisions. The invalidity of a
provision in a particular jurisdiction shall not invalidate or render unenforceable such provision
in any other jurisdiction.

party thereto (as amended or modified from time to time, the “Credit Agreement”; the terms
defined therein being used herein as therein defined) outstanding on such date.

The Borrower promises to pay interest on the unpaid principal amount of each Advance from the
date of such Advance until such principal amount is paid in full, at such interest rates, and

Promissory Note.

This Promissory Note is one of the Notes referred to in, and is entitled to the benefits of,

Advance being evidenced by this Promissory Note and (ii) contains provisions for acceleration of
the maturity hereof upon the happening of certain stated events and also for prepayments on account
of principal hereof prior to the maturity hereof upon the terms and conditions therein specified.
