2001 LONG-TERM INCENTIVE PLAN

RESTRICTED STOCK PROGRAM AGREEMENTS

     This Amendment to the Restricted Stock Program Agreements (this “Amendment”), is entered into
between Matrixx Initiatives, Inc., a Delaware corporation (the “Company”), and Edward Faber
(the “Director”), as of October 18, 2006 (the “Effective Date”).

RECITALS

     A. The Company entered into a restricted stock program agreement with the Director on January
3, 2006 (together, the “Restricted Stock Program Agreement”) pursuant to the Matrixx
Initiatives, Inc. 2001 Long-Term Incentive Plan, as amended (formerly known as the Gumtech
International, Inc. 2001 Long-Term Incentive Plan) (the “Plan”).

     B. The Board of Directors has implemented a mandatory director retirement policy requiring
directors to retire immediately prior to the Annual Meeting of Stockholders held in the year of the
director’s 72nd birthday; the policy also requires that the Director, who was in excess of 72 years
of age on May 18, 2005, retire immediately prior to the Annual Meeting of Stockholders to be held
in 2008.

     C. The Compensation Committee of the Board of Directors, acting as the Plan Committee,
believes that entering into this Amendment is appropriate given the mandatory director retirement
policy.

     NOW, THEREFORE, in consideration of the mutual covenants and conditions in this Agreement and
for other good and valuable consideration, the Company and the Director agree as follows:

1. Amendment of Section 3(B). Section 3(B) of the Restricted Stock Program
Agreement is hereby deleted and replaced in its entirety by the following:

                    B. Return of Common Stock.

     Except as set forth in this Agreement, the Director will transfer those shares
of Common Stock for which the restrictions have not lapsed under Section 3.C. to
the Company immediately and without any payment to the Director if the Director
ceases to serve on the Board of Directors or any committee thereof for any reason
other than death; Disability (as defined in the Plan); or mandatory retirement, as
provided in the Company’s Corporate Governance Principles, as amended from time to
time.

2. Amendment of Section 3(C). Section 3(C) of the Restricted Stock Program
Agreement is hereby deleted and replaced in its entirety by the following:

 

 

                    C. Lapse of Restrictions.

     Subject to the other conditions in this Section 3, the restrictions on
disposition of the shares of Common Stock issued hereunder will lapse upon the
first of the following dates: (i) the third anniversary of the Date of Grant, (ii)
the effective date of a Change of Control (as that term is defined in the form of
Change of Control Agreement filed with the Securities Exchange Commission on March
13, 2006 as Exhibit 10.12 to the Company’s 2005 Form 10-K), and (iii) the
date on which the Director ceases to serve on the Board of Directors or any
committee thereof on account of his death; Disability (as that term is defined in
the Plan); or mandatory retirement, as provided in the Company’s Corporate
Governance Principles, as amended from time to time; provided, however, that the
restrictions on the disposition of the shares of Common Stock issued hereunder will
not lapse unless the Director is serving on the Board of Directors or any committee
thereof as of the date the restrictions expire.

3. Binding Effect. This Amendment shall be binding upon and inure to the benefit of
the parties hereto and their respective heirs, administrators, executors, successors,
and assigns. The parties hereby consent to the personal jurisdiction of the courts
located in the State of Arizona.

4. Execution in Counterparts. This Amendment may be executed in one or more
counterparts, each of which shall be considered an original, but all of which together
shall be deemed to be one and the same document.

     IN WITNESS WHEREOF, the parties hereto have executed this Agreement as of the date first
written above.

Each Lender severally agrees, on the terms and conditions hereinafter set forth, to make Advances

issued by each Issuing Bank not to exceed at any time the lesser of (x) the Letter of Credit
Facility at such time and (y) such Issuing Bank’s Letter of Credit Commitment at such time and (ii)
for each such Letter of Credit not to exceed an amount equal to the

13

 

Unused Commitments of the Lenders at such time. No Letter of Credit shall have an expiration
date (including all rights of the Borrower or the beneficiary to require renewal) later than five
Business Days before the Termination Date; provided that no Letter of Credit may expire
after the Termination Date of any Non-Consenting Lender if, after giving effect to such Letter of
Credit, the aggregate Revolving Credit Commitments of the Consenting Lenders (including any
replacement Lenders) for the period following such Termination Date would be less than the
Available Amount of the Letters of Credit expiring after such Termination 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 (New York City
time) 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 (New York City time) 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. (New York City time) on the date of such Borrowing, and in the
case of a Borrowing consisting of Eurodollar Rate Advances, before 11:00 A.M. (New York City time)
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 portion 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 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
portion 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

14

 

corresponding amount. If and to the extent that such Lender shall not have so made such
ratable portion 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. Issuance of and Drawings and Reimbursement Under Letters of Credit.
(a) Request for Issuance. (i) Each Letter of Credit shall be issued upon notice, given
not later than 11:00 A.M. (New York City time) on the third Business Day prior to the date of the
proposed issuance of such Letter of Credit (or on such shorter notice as the applicable Issuing
Bank may agree), by the Borrower to any Issuing Bank, and such Issuing Bank shall give the Agent,
prompt notice thereof. Each such notice by the Borrower of issuance of a Letter of Credit (a
“Notice of Issuance”) shall be by facsimile or telephone, confirmed immediately in writing,
specifying therein the requested (A) date of such issuance (which shall be a Business Day), (B)
Available Amount of such Letter of Credit, (C) expiration date of such Letter of Credit (which
shall not be later than five Business Days before the Termination Date), (D) name and address of
the beneficiary of such Letter of Credit and (E) form of such Letter of Credit. Each Letter of
Credit shall be issued pursuant to such application for letter of credit as such Issuing Bank may
specify to the Borrower for use in connection with such requested Letter of Credit (a “Letter
of Credit Application”). If the requested form of such Letter of Credit is acceptable to such
Issuing Bank in its sole discretion, such Issuing Bank will, upon fulfillment of the applicable
conditions set forth in Article III, make such Letter of Credit available to the Borrower at its
office referred to in Section 8.02 or as otherwise agreed with the Borrower in connection with such
issuance. In the event and to the extent that the provisions of any Letter of Credit Application
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 may impose
any additional conditions on the issuance of a Letter of Credit nor obligations of the Borrower to
the Issuing Bank, other than as stated in this Agreement.

          (b) Participations. By the issuance of a Letter of Credit (or an amendment to a
Letter of Credit increasing the amount thereof) and without any further action on the part of the
applicable Issuing Bank or the Lenders, such Issuing Bank hereby grants to each Lender, and each
Lender hereby acquires from such Issuing Bank, a participation in such Letter of Credit equal to
such Lender’s Ratable Share of the Available Amount of such Letter of Credit. The Borrower hereby
agrees to each such participation. In consideration and in furtherance of the foregoing, each
Lender hereby absolutely and unconditionally agrees to pay to the Agent, for the account of such
Issuing Bank, such Lender’s Ratable Share of each drawing made under a Letter of Credit funded by
such Issuing Bank and not reimbursed by the Borrower on the date made, or of any reimbursement
payment required to be refunded to the Borrower for any reason, which amount will be advanced, and
deemed to be an Advance to the Borrower hereunder, regardless of the satisfaction of the conditions
set forth in Section 3.02. Each Lender acknowledges and agrees that its obligation to acquire
participations pursuant to this paragraph in respect of Letters of Credit is absolute and
unconditional and shall not be affected by any circumstance

15

 

whatsoever, including any amendment, renewal or extension of any Letter of Credit or the
occurrence and continuance of a Default or reduction or termination of the Revolving Credit
Commitments, and that each such payment shall be made without any offset, abatement, withholding or
reduction whatsoever. Each Lender further acknowledges and agrees that its participation in each
Letter of Credit will be automatically adjusted to reflect such Lender’s Ratable Share of the
Available Amount of such Letter of Credit at each time such Lender’s Revolving Credit Commitment is
increased pursuant to Section 2.18, reduced on a date prior to the date that the Termination Date
may have been extended pursuant to Section 2.19, amended pursuant to an assignment in accordance
with Section 8.07 or otherwise pursuant to this Agreement.

          (c) Drawing and Reimbursement. The payment by an Issuing Bank of a draft drawn under
any Letter of Credit which is not reimbursed by the Borrower on the date made shall constitute for
all purposes of this Agreement the making by any such Issuing Bank of an Advance regardless of the
conditions set forth in Section 3.02, which shall be a Base Rate Advance, in the amount of such
draft, without regard to whether the making of such an Advance would exceed such Issuing Bank’s
Unused Commitment. Each Issuing Bank shall give prompt notice of each drawing under any Letter of
Credit issued by it to the Borrower and the Agent. Upon written demand by such Issuing Bank, with
a copy of such demand to the Agent and the Borrower, each Lender shall pay to the Agent such
Lender’s Ratable Share of such outstanding Advance pursuant to Section 2.03(b). Each Lender
acknowledges and agrees that its obligation to make Advances pursuant to this paragraph in respect
of Letters of Credit is absolute and unconditional and shall not be affected by any circumstance
whatsoever, including any amendment, renewal or extension of any Letter of Credit or the occurrence
and continuance of a Default or reduction or termination of the Revolving Credit Commitments, and
that each such payment shall be made without any offset, abatement, withholding or reduction
whatsoever. Promptly after receipt thereof, the Agent shall transfer such funds to such Issuing
Bank. Each Lender agrees to fund its Ratable Share of an outstanding Advance on (i) the Business
Day on which demand therefor is made by such Issuing Bank, provided that notice of such
demand is given not later than 11:00 A.M. (New York City time) on such Business Day, or (ii) the
first Business Day next succeeding such demand if notice of such demand is given after such time.
If and to the extent that any Lender shall not have so made the amount of such Advance available to
the Agent, such Lender agrees to pay to the Agent forthwith on demand such amount together with
interest thereon, for each day from the date of demand by any such Issuing Bank until the date such
amount is paid to the Agent, at the Federal Funds Rate for the account of such Issuing Bank. If a
Lender shall pay to the Agent any amount for the account of any such Issuing Bank on any Business
Day, such amount so paid in respect of principal shall constitute an Advance made by such Lender on
such Business Day for purposes of this Agreement, and the outstanding principal amount of the
Advance made by such Issuing Bank shall be reduced by such amount on such Business Day.

          (d) Letter of Credit Reports. Each Issuing Bank shall furnish (A) to the Agent and
each Lender 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 and each Lender 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.

          (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) shall not relieve any other Lender of its
obligation hereunder to make its Advance on such date, 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 such date.

16

 

          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 Acceptance 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 September 30, 2006, and on the
Termination Date.

          (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 September 30, 2006, 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
of 0.125% per annum on the Available Amount of each Letter of Credit issued by such Issuing
Bank, payable in arrears quarterly on the last day of each March, June, September and
December, commencing with the first such quarter in which any Letter of Credit is issued and
on the Termination Date, 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) Utilization Fees. If at any time the aggregate principal amount of the Total
Outstandings exceeds an amount equal to fifty percent (50%) of the aggregate Revolving Credit
Commitments, the Borrower shall pay to the Agent, for the ratable benefit of the Lenders, a
utilization fee (the “Utilization Fees”) equal to the product of (i) the average daily
Total Outstandings, calculated from the date the Total Outstandings exceeds an amount equal to
fifty percent (50%) of the aggregate Revolving Credit Commitments but excluding the date the Total
Outstandings falls below an amount equal to fifty percent (50%), times (ii) a per annum percentage
equal to the Applicable Rate for Utilization Fees. The Utilization Fees shall be payable in
arrears on the last day of each fiscal quarter (as well as on the Termination Date) for the fiscal
quarter (or portion thereof) then ending, beginning with the first of such dates to occur after the
Effective Date.

          (d) 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 dated September 1,
2006, as amended from time to time.

          SECTION 2.05. Optional Termination or Reduction of the Commitments. 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 of the Lenders, 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.

          SECTION 2.06. Repayment of Advances and Letter of Credit Drawings. (a) The Borrower
shall repay to the Agent for the ratable account of the Lenders on the Termination Date applicable
to such Lender the aggregate principal amount of the Advances made by such Lender and then
outstanding.

17

 

          (b) The obligations of the Borrower hereunder relating to any Letter of Credit shall be
unconditional and irrevocable, and shall be paid strictly in accordance with the terms of this
Agreement under all circumstances, including, without limitation, the following circumstances (it
being understood that any such payment by the Borrower is without prejudice to, and does not
constitute a waiver of, any rights the Borrower might have or might acquire as a result of the
payment by any Lender of any draft or the reimbursement by the Borrower thereof):

     (i) any lack of validity or enforceability of this Agreement, any Note, any Letter of
Credit or any other agreement or instrument relating thereto (all of the foregoing being,
collectively, the “L/C Related Documents”);

     (ii) any change in the time, manner or place of payment of, or in any other term of,
all or any of the obligations of the Borrower in respect of any L/C Related Document or any
other amendment or waiver of or any consent to departure from all or any of the L/C Related
Documents;

     (iii) the existence of any claim, set-off, defense or other right that the Borrower may
have at any time against any beneficiary or any transferee of a Letter of Credit (or any
Persons for which any such beneficiary or any such transferee may be acting), any Issuing
Bank, any Agent, any Lender or any other Person, whether in connection with the transactions
contemplated by the L/C Related Documents or any unrelated transaction;

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

     (v) payment by any Issuing Bank under a Letter of Credit against presentation of a
draft or certificate that does not strictly comply with the terms of such Letter of Credit;

     (vi) any exchange, release or non-perfection of any collateral, or any release or
amendment or waiver of or consent to departure from any guarantee, for all or any of the
obligations of the Borrower in respect of the L/C Related Documents; or

     (vii) any other circumstance or happening whatsoever, whether or not similar to any of
the foregoing, including, without limitation, any other circumstance that might otherwise
constitute a defense available to, or a discharge of, the Borrower or a guarantor;

provided, however, that nothing in this Section 2.06 shall limit the rights
of the Borrower under Section 8.12.

          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.

18

 

     (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.

          (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.

          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, with respect to any Eurodollar Rate Advances, the Required Lenders notify the Agent
that the Eurodollar Rate for any Interest Period for such Advances will not adequately reflect the
cost to such Required Lenders of making, funding or maintaining their respective Eurodollar Rate
Advances for such Interest Period, the Agent shall forthwith so notify the Borrower and the
Lenders, whereupon (i) each Eurodollar Rate Advance will automatically, on the last day of the then
existing Interest Period therefor, Convert into a Base Rate Advance, and (ii) the obligation of the
Lenders to make, 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.

          (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

19

 

     (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 (New York City time) 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 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, 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 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. The Borrower may,
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. (New York City time) on the date of such
prepayment, in the case of Base Rate Advances, to the Agent stating the proposed date and aggregate
principal amount of the prepayment, and if such notice is given the Borrower shall, prepay the
outstanding principal amount of the Advances comprising part of the same Borrowing in whole or
ratably in part, together with accrued interest to the date of such prepayment on the principal
amount prepaid; provided, however, that (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(c).

          (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 Arizona laws,
rules or regulations, including the 1984 Order and the 1986 Order, or applicable resolutions of the
Board of Directors of the Borrower and (ii) on the Termination Date applicable to any
Non-Consenting Lender, 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, in an
amount equal to the excess of (x) the sum of the Available Amount of all Letters of Credit plus the
aggregate principal amount of the Advances then outstanding over (y) the aggregate Commitments to
be outstanding immediately after giving effect to such Termination Date.

          SECTION 2.11. Increased Costs. (a) If, due to either (i) the introduction of or any
change in or in the interpretation of any law or regulation or (ii) the compliance with any new
guideline or unanticipated request from any central bank or other governmental authority (whether
or not having the force of law), there shall be any increase in the cost to any Lender of agreeing
to make or making, funding or maintaining Eurodollar Rate Advances or agreeing to issue or of
issuing or maintaining or participating in Letters of Credit (excluding for purposes of this
Section 2.11 any such increased costs resulting from (i) Taxes or Other Taxes (as to which Section
2.14 shall govern), (ii) changes in the basis of taxation of overall net income or overall gross
income by the United States or by the foreign jurisdiction or state under the laws of which such
Lender is organized or has its Applicable Lending Office or any political subdivision thereof and
(iii) reserve requirements included in the calculation required by Section 2.11(d)),

20

 

then the Borrower shall from time to time, within 30 days of demand by such Lender (with a
copy of such demand to the Agent), pay to the Agent for the account of such Lender additional
amounts that the Lender reasonably determines sufficient to compensate such Lender for such
increased cost. A certificate as to the amount of such increased cost, submitted to the Borrower
and the Agent by such Lender, shall be conclusive and binding for all purposes, absent manifest
error.

          (b) If any Lender determines that compliance with any new law or regulation or any new
guideline or unanticipated request from any central bank or other governmental authority (whether
or not having the force of law) affects or would affect the amount of capital required or expected
to be maintained by such Lender or any corporation controlling such Lender and that the amount of
such capital is increased by or based upon the existence of such Lender’s commitment to lend or to
issue or participate in Letters of Credit hereunder and other commitments of this type, then,
within 30 days of demand by such Lender (with a copy of such demand to the Agent), the Borrower
shall pay to the Agent for the account of such Lender, from time to time as specified by such
Lender, additional amounts that the Lender reasonably determines sufficient to compensate such
Lender or such corporation in the light of such circumstances, to the extent that such Lender
reasonably determines such increase in capital to be allocable to the existence of such Lender’s
commitment to lend or to issue or participate in Letters of Credit hereunder. A certificate as to
such amounts submitted to the Borrower and the Agent by such Lender shall be conclusive and binding
for all purposes, absent manifest error.

          (c) Each Lender will notify the Borrower of any change that will entitle such Lender to
compensation under Section 2.11(a) or (b) as promptly as practicable, but in any event within 90
days after such Lender obtains knowledge thereof; provided, however, that, if any
Lender fails to give such notice within 90 days after it obtains knowledge of such change, such
Lender shall, with respect to compensation payable in respect of any costs resulting from such
change, only be entitled to payment for costs incurred from and after the date that such Lender
does give such notice plus, if such change shall have retroactive effect, costs resulting from such
change during the period of retroactive effect thereof. Any Lender claiming any additional amounts
payable pursuant to this Section agrees to use reasonable efforts (consistent with its internal
policy and legal and regulatory restrictions) to change the jurisdiction of its Eurodollar Lending
Office if the making of such a change would avoid the need for, or reduce the amount of, any such
additional amounts that may thereafter accrue and would not, in the reasonable judgment of such
Lender, be otherwise disadvantageous to such Lender.

          (d) The Borrower shall pay to the Agent for the account of each Lender that requests such a
payment, so long as such Lender shall be required under regulations of the Board of Governors of
the Federal Reserve System to maintain reserves with respect to Eurocurrency Liabilities, an
additional amount determined by such Lender up to but not exceeding an amount equal to the sum of
the products of the following for each Eurodollar Rate Advance for each day during the applicable
Interest Period therefor:

     (i) the principal amount of such Eurodollar Rate Advance outstanding on such day;
multiplied by

     (ii) the remainder of (x) a fraction the numerator of which is the rate (expressed as a
decimal) at which interest accrues on such Eurodollar Rate Advance for such Interest Period
as provided in this Agreement (less the Applicable Rate for Eurodollar Rate Advances), and
the denominator of which is one minus the effective rate (expressed as a decimal) at which
such reserve requirements are imposed on such Lender on such day, minus (y) such numerator;
multiplied by

     (iii) 1/360.

21

 

          Such additional amount shall be determined by such Lender and notified to the Borrower through
the Agent and shall be payable on each date on which interest is payable on such Eurodollar Rate
Advance. Any such determination, when submitted by a Lender to the Borrower and accompanied by the
calculations showing the basis for such determination, shall be conclusive and binding for all
purposes absent manifest error.

          SECTION 2.12. Illegality. Notwithstanding any other provision of this Agreement, if
any Lender shall notify the Agent that the introduction of or any change in or in the
interpretation of any law or regulation makes it unlawful, or any central bank or other
governmental authority asserts that it is unlawful, for any Lender or its Eurodollar Lending Office
to perform its obligations hereunder to make Eurodollar Rate Advances or to fund or maintain
Eurodollar Rate Advances hereunder, (a) each Eurodollar Rate Advance will automatically, on the
last day of the applicable Interest Period or, if required by applicable law, immediately upon such
demand, Convert into a Base Rate Advance and (b) 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 2.13. 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. (New York City
time) 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
2.11, 2.14 or 8.04(c)) 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 or an extension of the Termination Date pursuant
to Section 2.19, 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
or Extension Date, as the case may be, 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 Acceptance 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 Acceptance, 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 Acceptance 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 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 or the Federal Funds Rate and of fees and Letter of Credit 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

22

 

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) Any and all payments by the Borrower to or for the account
of any Lender or the Agent hereunder or under the Notes or any other documents to be delivered
hereunder shall be made, in accordance with Section 2.13 or the applicable provisions of such other
documents, free and clear of and without deduction for any and all present or future taxes, levies,
imposts, deductions, charges or withholdings, and all liabilities with respect thereto,
excluding, in the case of each Lender and the Agent, taxes imposed on its overall net
income, and franchise taxes imposed on it in lieu of net income taxes, by the United States and the
jurisdiction under the laws of which such Lender or the Agent (as the case may be) is organized or
does business or any political subdivision thereof and, in the case of each Lender, taxes imposed
on its overall net income, and franchise taxes imposed on it in lieu of net income taxes, by the
jurisdiction of such Lender’s Applicable Lending Office or any political subdivision thereof (all
such non-excluded taxes, levies, imposts, deductions, charges, withholdings and liabilities in
respect of payments hereunder or under the Notes being hereinafter referred to as “Taxes”).
If the Borrower shall be required by law to deduct any Taxes from or in respect of any sum payable
hereunder or under any Note or any other documents to be delivered hereunder to any Lender or the
Agent, (i) the sum payable shall be increased as may be necessary so that after making all required
deductions (including deductions applicable to additional sums payable under this Section 2.14)
such Lender or the Agent (as the case may be) receives an amount equal to the sum it would have
received had no such deductions been made, (ii) the Borrower shall make such deductions and (iii)
the Borrower shall pay the full amount deducted to the relevant taxation authority or other
authority in accordance with applicable law.

          (b) In addition, the Borrower shall pay any present or future stamp or documentary taxes or
any other excise or property taxes, charges or similar levies that arise from any payment made
hereunder or under the Notes or any other documents to be delivered hereunder or from the
execution, delivery or registration of, performing under, or otherwise with respect to, this
Agreement or the Notes or any other documents to be delivered hereunder (hereinafter referred to as
“Other Taxes”).

          (c) The Borrower shall indemnify each Lender and the Agent for and hold it harmless against
the full amount of Taxes or Other Taxes (including, without limitation, taxes of any kind imposed
or asserted by any jurisdiction on amounts payable under this Section 2.14) imposed on or paid by
such Lender or the Agent (as the case may be) and any liability (including penalties, interest and
expenses) arising therefrom or with respect thereto. This indemnification shall be made within 30
days from the date such Lender or the Agent (as the case may be) makes written demand therefor.
Such demand shall be made as promptly as practicable, but in any event within 90 days after such
Lender or the Agent (as the case may be) obtains actual knowledge of such event; provided,
however, that if any Lender or the Agent fails to make such demand within 90 days after
such Lender or the Agent (as the case may be) obtains knowledge of such event, such Lender or the
Agent shall, with respect to compensation payable in respect of such event, not be entitled to
compensation in respect of the costs and losses

23

 

incurred between the 90th day after such Lender or the Agent (as the case may be) obtains
actual knowledge of such event and the date such Lender or the Agent makes such demand.

          (d) Within 30 days after the date of any payment of Taxes, the Borrower shall furnish to the
Agent, at its address referred to in Section 8.02, the original or a certified copy of a receipt
evidencing such payment to the extent such a receipt is issued therefor, or other written proof of
payment thereof that is reasonably satisfactory to the Agent. In the case of any payment hereunder
or under the Notes or any other documents to be delivered hereunder by or on behalf of the Borrower
through an account or branch outside the United States or by or on behalf of the Borrower by a
payor that is not a United States person, if the Borrower determines that no Taxes are payable in
respect thereof, the Borrower shall furnish, or shall cause such payor to furnish, to the Agent, at
such address, an opinion of counsel acceptable to the Agent stating that such payment is exempt
from Taxes. For purposes of this subsection (d) and subsection (e), the terms “United
States” and “United States person” shall have the meanings specified in Section 7701 of
the Internal Revenue Code.

          (e) Each Lender organized under the laws of a jurisdiction outside the United States (i) on or
prior to the date of its execution and delivery of this Agreement in the case of each Initial
Lender and on the date of the Assumption Agreement or the Assignment and Acceptance pursuant to
which it becomes a Lender in the case of each other Lender, (ii) at any time that a change of
circumstances occurs of which such Lender is aware that makes any information on the form so
provided incorrect and (iii) from time to time thereafter as reasonably requested in writing by the
Borrower (but only so long as such Lender remains lawfully able to do so), shall provide each of
the Agent and the Borrower with two original Internal Revenue Service Forms W-8BEN or W-8ECI or
other relevant Form W-8, as appropriate, or any successor or other form prescribed by the Internal
Revenue Service, certifying that such Lender is exempt from or entitled to a reduced rate of United
States withholding tax on payments pursuant to this Agreement or the Notes. Further, each such
Lender that is not an exempt recipient listed in Section 6049(b)(4) of the Internal Revenue Code
shall provide the Borrower and the Agent with the appropriate Internal Revenue Service Form W-8 or
Internal Revenue Service Form W-9, as appropriate, or other successor form prescribed by the
Internal Revenue Service, certifying that it is exempt from United States back-up withholding. If
the form provided by a Lender at the time such Lender first becomes a party to this Agreement
indicates a United States interest withholding tax rate in excess of zero, withholding tax at such
rate shall be considered excluded from Taxes unless and until such Lender provides the appropriate
forms certifying that a lesser rate applies, whereupon withholding tax at such lesser rate only
shall be considered excluded from Taxes for periods governed by such form; provided,
however, that, if at the date of the Assignment and Acceptance pursuant to which a Lender
assignee becomes a party to this Agreement, the Lender assignor was entitled to payments under
subsection (a) in respect of United States withholding tax with respect to interest paid at such
date, then, to such extent, the term Taxes shall include (in addition to withholding taxes that may
be imposed in the future or other amounts otherwise includable in Taxes) United States withholding
tax, if any, applicable with respect to the Lender assignee on such date. If any form or document
referred to in this subsection (e) requires the disclosure of information, other than information
necessary to compute the tax payable and information required on the date hereof by Internal
Revenue Service Form W-8BEN or W-8ECI, that the Lender reasonably considers to be confidential, the
Lender shall give notice thereof to the Borrower and shall not be obligated to include in such form
or document such confidential information.

          (f) For any period with respect to which a Lender has failed to provide the Borrower with
the appropriate form, certificate or other document described in Section 2.14(e) (other
than if such failure is due to a change in law, or in the interpretation or application
thereof, occurring subsequent to the date on which a form, certificate or other document originally
was required to be provided, or if such form, certificate or other document otherwise is not
required under subsection (e) above), such Lender shall not be entitled to gross up under Section
2.14(a) and shall not be entitled to indemnification under

24

 

Section 2.14(a) or (c) with respect to Taxes imposed by the United States by reason of such
failure; provided, however, that should a Lender become subject to Taxes because of
its failure to deliver a form, certificate or other document required hereunder, the Borrower shall
take such steps as the Lender shall reasonably request to assist the Lender to recover such Taxes.

          (g) Any Lender claiming any additional amounts payable pursuant to this Section 2.14 agrees to
use reasonable efforts (consistent with its internal policy and legal and regulatory restrictions)
to change the jurisdiction of its Eurodollar Lending Office if the making of such a change would
avoid the need for, or reduce the amount of, any such additional amounts that may thereafter accrue
and would not, in the reasonable judgment of such Lender, be otherwise disadvantageous to such
Lender.

          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 owing to it (other than as payment of an Advance made by an Issuing Bank
pursuant to the first sentence of Section 2.03(c) or pursuant to Section 2.11, 2.14 or 8.04(c)) 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 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.

          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(d) 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 Acceptance 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

25

 

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 for general corporate purposes of the
Borrower.

          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 scheduled Termination Date then in effect (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
$600,000,000 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.

          (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 and
each Eligible Assignee that agrees to an extension of the Termination Date in accordance with
Section 2.19(c), 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:

26

 

     (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

     (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. (New York City time), by
telecopier, of the occurrence of the Commitment Increase to be effected on such Increase Date and
shall record in the Register the relevant information with respect to each Increasing Lender and
each Assuming Lender on such date. Each Increasing Lender and each Assuming Lender shall, before
2:00 P.M. (New York City time) 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 portion 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 portion 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 portion 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 portion 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. Extension of Termination Date. (a) Once per year and at least 60 days
but not more than 90 days prior to any anniversary of the Effective Date, the Borrower, by written
notice to the Agent, may request an extension of the Termination Date in effect at such time by one
year from its then scheduled expiration. The Agent shall promptly notify each Lender of such
request, and each Lender shall in turn, in its sole discretion, not later than 20 days prior to
such anniversary date, notify the Borrower and the Agent in writing as to whether such Lender will
consent to such extension. If any Lender shall fail to notify the Agent and the Borrower in
writing of its consent to any such request for extension of the Termination Date at least 20 days
prior to the applicable anniversary date, such Lender shall be deemed to be a Non-Consenting Lender
with respect to such request. The Agent shall notify the Borrower not later than 15 days prior to
the applicable anniversary date of the decision of the Lenders regarding the Borrower’s request for
an extension of the Termination Date.

27

 

          (b) If all the Lenders consent in writing to any such request in accordance with subsection
(a) of this Section 2.19, the Termination Date in effect at such time shall, effective as at the
applicable anniversary date (the “Extension Date”), be extended for one year;
provided that on each Extension Date the applicable conditions set forth in Article III
shall be satisfied and on the Extension Date a duly authorized officer of the Borrower shall have
delivered to the Agent a certificate stating that the conditions set forth in Section 3.02(a) and
(b) are satisfied. If less than all of the Lenders consent in writing to any such request in
accordance with subsection (a) of this Section 2.19, the Termination Date in effect at such time
shall, effective as at the applicable Extension Date and subject to subsection (d) of this Section
2.19, be extended as to those Lenders that so consented (each a “Consenting Lender”) but
shall not be extended as to any other Lender (each a “Non-Consenting Lender”). To the
extent that the Termination Date is not extended as to any Lender pursuant to this Section 2.19 and
the Revolving Credit Commitment of such Lender is not assumed in accordance with subsection (c) of
this Section 2.19 on or prior to the applicable Extension Date, the Revolving Credit Commitment and
Unissued Letter of Credit Commitment, if any, of such Non-Consenting Lender shall automatically
terminate in whole on such unextended Termination Date without any further notice or other action
by the Borrower, such Lender or any other Person; provided that such Non-Consenting
Lender’s rights under Sections 2.11, 2.14 and 8.04, and its obligations under Sections 7.05 and
8.08, shall survive the Termination Date for such Lender as to matters occurring prior to such
date. It is understood and agreed that no Lender shall have any obligation whatsoever to agree to
any request made by the Borrower for any requested extension of the Termination Date.

          (c) If less than all of the Lenders consent to any such request pursuant to subsection (a) of
this Section 2.19, the Agent shall promptly so notify the Consenting Lenders, and each Consenting
Lender may, in its sole discretion, give written notice to the Agent not later than 10 days prior
to the Extension Date of the amount of the Non-Consenting Lenders’ Revolving Credit Commitments for
which it is willing to accept an assignment in accordance with Section 8.07(a). If the Consenting
Lenders notify the Agent that they are willing to accept assignments of Revolving Credit
Commitments in an aggregate amount that exceeds the amount of the Revolving Credit Commitments of
the Non-Consenting Lenders, such Revolving Credit Commitments shall be allocated among the
Consenting Lenders willing to accept such assignments in such amounts as are agreed between the
Borrower and the Agent. If after giving effect to the assignments of Revolving Credit Commitments
described above there remains any Revolving Credit Commitments of Non-Consenting Lenders, the
Borrower may arrange for one or more Eligible Assignees as Assuming Lenders to assume, effective as
of the Extension Date, any Non-Consenting Lender’s Revolving Credit Commitment and all of the
obligations of such Non-Consenting Lender under this Agreement thereafter arising, without recourse
to or warranty by, or expense to, such Non-Consenting Lender; provided, however,
that the amount of the Revolving Credit Commitment of any such Assuming Lender as a result of such
substitution shall in no event be less than $10,000,000 unless the amount of the Revolving Credit
Commitment of such Non-Consenting Lender is less than $10,000,000, in which case such Assuming
Lender shall assume all of such lesser amount; and provided further that:

     (i) any such Consenting Lender or Assuming Lender shall have paid to such
Non-Consenting Lender (A) the aggregate principal amount of, and any interest accrued and
unpaid to the effective date of the assignment on, the outstanding Advances, if any, of such
Non-Consenting Lender plus (B) any accrued but unpaid fees owing to such
Non-Consenting Lender as of the effective date of such assignment;

     (ii) all additional cost reimbursements, expense reimbursements and indemnities then
due and payable to such Non-Consenting Lender, and all other accrued and unpaid amounts
owing to such Non-Consenting Lender hereunder, as of the effective date of such assignment
shall have been paid to such Non-Consenting Lender; and

28

 

     (iii) with respect to any such Assuming Lender, the applicable processing and
recordation fee required under Section 8.07(a) for such assignment shall have been paid;

provided further that such Non-Consenting Lender’s rights under Sections 2.11, 2.14
and 8.04, and its obligations under Sections 7.05 and 8.08, shall survive such substitution as to
matters occurring prior to the date of substitution. At least three Business Days prior to any
Extension Date, (A) each such Assuming Lender, if any, shall have delivered to the Borrower and the
Agent an Assumption Agreement, duly executed by such Assuming Lender, such Non-Consenting Lender,
the Borrower and the Agent, (B) any such Consenting Lender shall have delivered confirmation in
writing satisfactory to the Borrower and the Agent as to the increase in the amount of its
Revolving Credit Commitment and (C) each Non-Consenting Lender being replaced pursuant to this
Section 2.19 shall have delivered to the Agent any Note or Notes held by such Non-Consenting
Lender. Upon the payment of all amounts referred to in clauses (i), (ii) and (iii) of the
immediately preceding sentence, each such Consenting Lender or Assuming Lender, as of the Extension
Date, will be substituted for such Non-Consenting Lender under this Agreement and shall be a Lender
for all purposes of this Agreement, without any further acknowledgment by or the consent of the
other Lenders, and the obligations of each such Non-Consenting Lender hereunder arising after the
Extension Date shall, by the provisions hereof, be released and discharged.

          (d) If (after giving effect to any assignments or assumptions pursuant to subsection (c) of
this Section 2.19) Lenders having Revolving Credit Commitments equal to at least 50% of the
Revolving Credit Commitments in effect immediately prior to the Extension Date consent in writing
to a requested extension (whether by execution and delivery of an Assumption Agreement or
otherwise) not later than one Business Day prior to such Extension Date, the Agent shall so notify
the Borrower, and, subject to the satisfaction of the applicable conditions in Article III and the
delivery to the Agent on the Extension Date of a certificate of a duly authorized officer of the
Borrower stating that the conditions set forth in Section 3.02(a) and (b) are satisfied, the
Termination Date then in effect shall be extended for the additional one-year period as described
in subsection (a) of this Section 2.19, and all references in this Agreement, and in the Notes, if
any, to the “Termination Date” shall, with respect to each Consenting Lender and each
Assuming Lender for such Extension Date, refer to the Termination Date as so extended. Promptly
following each Extension Date, the Agent shall notify the Lenders (including, without limitation,
each Assuming Lender) of the extension of the scheduled Termination Date in effect immediately
prior thereto and shall thereupon record in the Register the relevant information with respect to
each such Consenting Lender and each such Assuming Lender.

Borrower, 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 Federal Bankruptcy Code, (A) the obligation of each
Lender to make Advances (other than Advances by an Issuing Bank or a Lender pursuant to Section
2.03(c)) 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.

40

 

          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, make demand upon the Borrower to, and forthwith upon such demand the
Borrower will, (a) pay to the Agent for the benefit of the Lenders in same day funds at the Agent’s
office designated in such demand, for deposit in the L/C Cash Deposit Account, an amount equal to
the aggregate Available Amount of all Letters of Credit then outstanding, provided,
however, that in the event of an actual or deemed entry of an order for relief with respect
to the Borrower under the Federal Bankruptcy Code, the Borrower will pay to the Agent on behalf of
the Lenders in same day funds , for deposit to the L/C Cash Deposit Account, an amount equal to 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, or (b)
make such other arrangements in respect of the outstanding Letters of Credit as shall be acceptable
to the Required Lenders. 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 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, and if so applied, then such reimbursement shall be deemed a repayment of the
corresponding Advance in respect of such Letter of Credit. 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 Notes 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. Authorization and Action. Each Lender (in its capacities as a Lender
and Issuing Bank, as applicable) hereby appoints and authorizes the Agent to take such action as
agent on its behalf and to exercise such powers and discretion under this Agreement as are
delegated to the Agent by the terms hereof, together with such powers and discretion as are
reasonably incidental thereto. As to any matters not expressly provided for by this Agreement
(including, without limitation, enforcement or collection of the Notes), the Agent shall not be
required to exercise any discretion or take any action, but shall be required to act or to refrain
from acting (and shall be fully protected in so acting or refraining from acting) upon the
instructions of the Required Lenders, and such instructions shall be binding upon all Lenders and
all holders of Notes; provided, however, that the Agent shall not be required to
take any action that exposes the Agent to personal liability or that is contrary to this Agreement
or applicable law. The Agent agrees to give to each Lender prompt notice of each notice or report
given to it by the Borrower pursuant to the terms of this Agreement.

          SECTION 7.02. Agent’s Reliance, Etc. Neither the Agent nor any of its directors,
officers, agents or employees shall be liable for any action taken or omitted to be taken by it or
them under or in connection with this Agreement, except for its or their own gross negligence or
willful misconduct. Without limitation of the generality of the foregoing, the Agent: (i) may
treat the Lender that made any Advance as the holder of the Indebtedness resulting therefrom until
the Agent receives and accepts an Assumption Agreement entered into by an Assuming Lender as
provided in Section 2.18 or 2.19, as the case may be, or an Assignment and Acceptance entered into
by such Lender, as assignor, and an Eligible Assignee, as assignee, as provided in Section 8.07;
(ii) may consult with legal counsel

41

 

(including counsel for the Borrower), independent public accountants and other experts
selected by it and shall not be liable for any action taken or omitted to be taken in good faith by
it in accordance with the advice of such counsel, accountants or experts; (iii) makes no warranty
or representation to any Lender and shall not be responsible to any Lender for any statements,
warranties or representations (whether written or oral) made in or in connection with this
Agreement; (iv) shall not have any duty to ascertain or to inquire as to the performance,
observance or satisfaction of any of the terms, covenants or conditions of this Agreement on the
part of the Borrower or the existence at any time of any Default or to inspect the property
(including the books and records) of the Borrower; (v) shall not be responsible to any Lender for
the due execution, legality, validity, enforceability, genuineness, sufficiency or value of, or the
perfection or priority of any lien or security interest created or purported to be created under or
in connection with, this Agreement or any other instrument or document furnished pursuant hereto;
and (vi) shall incur no liability under or in respect of this Agreement by acting upon any notice,
consent, certificate or other instrument or writing (which may be by facsimile) believed by it to
be genuine and signed or sent by the proper party or parties.

          SECTION 7.03. Bank of America and Affiliates. With respect to its Commitments, the
Advances made by it and any Note issued to it, Bank of America shall have the same rights and
powers under this Agreement 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, include Bank
of America in its individual capacity. Bank of America and its Affiliates may accept deposits
from, lend money to, act as trustee under indentures of, accept investment banking engagements from
and generally engage in any kind of business with, the Borrower, any of its Subsidiaries and any
Person who may do business with or own securities of the Borrower or any such Subsidiary, all as if
Bank of America were not the Agent and without any duty to account therefor to the Lenders. The
Agent shall have no duty to disclose any information obtained or received by it or any of its
Affiliates relating to the Borrower or any of its Subsidiaries to the extent such information was
obtained or received in any capacity other than as Agent.

          SECTION 7.04. Lender Credit Decision. Each Lender acknowledges that it has,
independently and without reliance upon the Agent or any other Lender and based on the financial
statements referred to in Section 4.01 and such other 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 and based on such documents and information as it shall deem appropriate at the time,
continue to make its own credit decisions in taking or not taking action under this Agreement.

          SECTION 7.05. Indemnification. (a) Each Lender severally agrees to indemnify the
Agent (to the extent not promptly reimbursed by the Borrower) from and against such Lender’s
Ratable Share of any and all liabilities, obligations, losses, damages, penalties, actions,
judgments, suits, costs, expenses or disbursements of any kind or nature whatsoever that may be
imposed on, incurred by, or asserted against the Agent in any way relating to or arising out of
this Agreement or any action taken or omitted by the Agent under this Agreement (collectively, the
“Indemnified Costs”), provided that no Lender shall be liable for any portion of
the Indemnified Costs resulting from the Agent’s gross negligence or willful misconduct. Without
limitation of the foregoing, each Lender agrees to reimburse the Agent promptly upon demand for its
Ratable Share of any out-of-pocket expenses (including counsel fees) incurred by the Agent in
connection with the preparation, execution, delivery, administration, modification, amendment or
enforcement (whether through negotiations, legal proceedings or otherwise) of, or legal advice in
respect of rights or responsibilities under, this Agreement, to the extent that the Agent is not
reimbursed for such expenses by the Borrower. In the case of any investigation, litigation or
proceeding giving rise to any Indemnified Costs, this Section 7.05 applies whether any such
investigation, litigation or proceeding is brought by the Agent, any Lender or a third party.

42

 

          (b) Each Lender severally agrees to indemnify the Issuing Banks (to the extent not promptly
reimbursed by the Borrower) from and against such Lender’s Ratable Share of any and all
liabilities, obligations, losses, damages, penalties, actions, judgments, suits, costs, expenses or
disbursements of any kind or nature whatsoever that may be imposed on, incurred by, or asserted
against any such Issuing Bank in any way relating to or arising out of this Agreement or any action
taken or omitted by such Issuing Bank hereunder or in connection herewith; provided,
however, that no Lender shall be liable for any portion of such liabilities, obligations,
losses, damages, penalties, actions, judgments, suits, costs, expenses or disbursements resulting
from such Issuing Bank’s gross negligence or willful misconduct. Without limitation of the
foregoing, each Lender agrees to reimburse any such Issuing Bank promptly upon demand for its
Ratable Share of any costs and expenses (including, without limitation, fees and expenses of
counsel) payable by the Borrower under Section 8.04, to the extent that such Issuing Bank is not
promptly reimbursed for such costs and expenses by the Borrower.

          (c) The failure of any Lender to reimburse the Agent or any Issuing Bank promptly upon demand
for its Ratable Share of any amount required to be paid by the Lenders to the Agent as provided
herein shall not relieve any other Lender of its obligation hereunder to reimburse the Agent or any
Issuing Bank for its Ratable Share of such amount, but no Lender shall be responsible for the
failure of any other Lender to reimburse the Agent or any Issuing Bank for such other Lender’s
Ratable Share of such amount. Without prejudice to the survival of any other agreement of any
Lender hereunder, the agreement and obligations of each Lender contained in this Section 7.05 shall
survive the payment in full of principal, interest and all other amounts payable hereunder and
under the Notes. Each of the Agent and each Issuing Bank agrees to return to the Lenders their
respective Ratable Shares of any amounts paid under this Section 7.05 that are subsequently
reimbursed by the Borrower.

          SECTION 7.06. Successor Agent. The Agent may resign at any time by giving written
notice thereof to the Lenders and the Borrower and may be removed at any time with or without cause
by the Required Lenders. Upon any such resignation or removal, the Required Lenders shall have the
right to appoint a successor Agent approved, so long as no Event of Default has occurred and is
continuing, by the Borrower, which consent shall not be unreasonably withheld or delayed. If no
successor Agent shall have been so appointed by the Required Lenders, and shall have accepted such
appointment, within 45 days after the retiring Agent’s giving of notice of resignation or the
Required Lenders’ removal of the retiring Agent, then the retiring Agent may, on behalf of the
Lenders, appoint a successor Agent, which shall be a commercial bank organized under the laws of
the United States of America or of any State thereof and having a combined capital and surplus of
at least $500,000,000; provided that if the 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 (a) the retiring Agent shall be discharged from
its duties and obligations hereunder and under the other Loan Documents and (b) all payments,
communications and determinations provided to be made by, to or through the Agent shall instead be
made by or to each Lender and the Issuing Banks directly, until such time as the Required Lenders
appoint a successor Agent as provided for above in this Section, and the Borrower and the Lenders
agree to negotiate in good faith to amend this Agreement to resolve any ambiguities and
inconsistencies resulting therefrom. Upon the acceptance of any appointment as Agent hereunder by
a successor Agent, such successor Agent shall thereupon succeed to and become vested with all the
rights, powers, discretion, privileges and duties of the retiring Agent, and the retiring Agent
shall be discharged from its duties and obligations under this Agreement. After any retiring
Agent’s resignation or removal hereunder as Agent, the provisions of this Article VII shall inure
to its benefit as to any actions taken or omitted to be taken by it while it was Agent under this
Agreement.

     Any resignation by Bank of America as Agent pursuant to this Section shall also constitute its
resignation as Issuing Bank as to Letters of Credit that may be issued after the date of such
resignations. Upon the acceptance of a successor’s appointment as Agent hereunder, (i) such
successor shall succeed to

43

 

and become vested with all of the rights, powers, privileges and duties of Bank of America as
retiring Issuing Bank as to Letters of Credit that may be issued after the date of such
resignations, (ii) the Bank of America as retiring Issuing Bank shall be discharged from all of its
respective duties and obligations hereunder or under the other Loan Documents as to Letters of
Credit that may be issued after the date of such resignations, and (iii) the successor Issuing Bank
shall issue letters of credit in substitution for such Letters of Credit, if any, outstanding at
the time of such succession, subject to the consent of the beneficiaries thereof, or make other
arrangements satisfactory to Bank of America as retiring Issuing Bank to effectively assume the
obligations of Bank of America as retiring Issuing Bank with respect to such Letters of Credit;
provided that, for purposes of clarification, Bank of America shall retain all rights and
obligations with respect to its issued Letters of Credit, if any, until such adequate alternative
arrangements have been consummated.

          SECTION 7.07. Other Agents. Each Lender hereby acknowledges that neither the
documentation agents nor any other Lender designated as any “Agent” on the signature pages hereof
has any rights, obligations or liability hereunder other than in its capacity as a Lender.

ARTICLE VIII

MISCELLANEOUS

          SECTION 8.01. Amendments, Etc. No amendment or waiver of any provision of this
Agreement or the Notes, 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, unless
in writing and signed by all the Lenders, do any of the following: (a) waive any of the conditions
specified in Section 3.01, (b) increase the Commitments of the Lenders, (c) reduce the principal
of, or interest on, the Advances or any fees or other amounts payable hereunder due to such
Lenders, (d) postpone any date fixed for any payment of principal of, or interest on, the Advances
or any fees payable hereunder due to such Lenders, (e) change the percentage of the Revolving
Credit Commitments or of the aggregate unpaid principal amount of the Advances, or the number of
Lenders, that shall be required for the Lenders or any of them to take any action hereunder or (f)
amend this Section 8.01; and provided further that (x) no amendment, waiver or
consent shall, unless in writing and signed by the Agent in addition to the Lenders required above
to take such action, affect the rights or duties of the Agent under this Agreement or any Note and
(y) no amendment, waiver or consent shall, unless in writing and signed by the Issuing Banks in
addition to the Lenders required above to take such action, adversely affect the rights or
obligations of the Issuing Banks in their capacities as such under this Agreement.

          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

44

 

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
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 email, 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.

45

 

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

          SECTION 8.04. Costs and Expenses. (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 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 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 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 each Lender and each of
their Affiliates and their officers, directors, employees, agents and advisors (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) (i) the Notes, this
Agreement, any of the transactions contemplated herein or the actual or proposed use of the
proceeds of the Advances 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, except to the extent 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 or willful misconduct,
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

46

 

any other Person, whether or not any Indemnified Party is otherwise a party thereto, unless
such litigation or proceeding is brought by or against the Borrower and the Borrower prevails in a
final, non-appealable judgment, in which case any fees or 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, and whether or not the transactions contemplated hereby are consummated.
Each party hereto also agrees not to assert any claim for special, indirect, consequential or
punitive damages against the other parties hereto, any of their Affiliates, or any of their
respective directors, officers, employees, attorneys and agents, 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.

          (c) 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 Notes 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.

          (d) 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 Notes due and payable pursuant to the
provisions of Section 6.01, each Lender 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 to or for the credit or the account of the Borrower against any and all of the
obligations of the Borrower now or hereafter existing under this Agreement and the Note held by
such Lender, whether or not such Lender shall have made any demand under this Agreement or such
Note and although such obligations may be unmatured. Each Lender 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
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. This Agreement shall become effective (other than
Section 2.01, which shall only become effective upon satisfaction of the conditions precedent set
forth in Section 3.01) 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.

47

 

          SECTION 8.07. Assignments and Participations. (a) Each Lender may and, if demanded
by the Borrower (following a demand by such Lender pursuant to Section 2.11 or 2.14) upon at least
five Business Days’ notice to such Lender and the Agent, will assign to one or more Persons all or
a portion of its rights and obligations under this Agreement (including, without limitation, all or
a portion of its Revolving Credit Commitment, its Unissued Letter of Credit Commitment, the
Advances owing to it, its participations in Letters of Credit and the Note or Notes held by it);
provided, however, that (i) each such assignment shall be of a constant, and not a
varying, percentage of all rights and obligations under this Agreement, (ii) except in the case of
an assignment to a Person that, immediately prior to such assignment, was a Lender or an assignment
of all of a Lender’s rights and obligations under this Agreement, the amount of the Revolving
Credit Commitment or Unissued Letter of Credit Commitment of the assigning Lender being assigned
pursuant to each such assignment (determined as of the date of the Assignment and Acceptance with
respect to such assignment) shall in no event be less than $5,000,000 (unless such assignment is
for the entire remaining amount of the assigning Lender’s Revolving Credit Commitment) or an
integral multiple of $1,000,000 in excess thereof unless the Borrower and the Agent otherwise
agree, (iii) each such assignment shall be to an Eligible Assignee, (iv) each such assignment made
as a result of a demand by the Borrower pursuant to this Section 8.07(a) shall be arranged by the
Borrower after consultation with the Agent and shall be either an assignment of all of the rights
and obligations of the assigning Lender under this Agreement or an assignment of a portion of such
rights and obligations made concurrently with another such assignment or other such assignments
that together cover all of the rights and obligations of the assigning Lender under this Agreement,
(v) no Lender shall be obligated to make any such assignment as a result of a demand by the
Borrower pursuant to this Section 8.07(a) unless and until such Lender shall have received one or
more payments from either the Borrower or one or more Eligible Assignees in an aggregate amount at
least equal to the aggregate outstanding principal amount of the Advances owing to such Lender,
together with accrued interest thereon to the date of payment of such principal amount and all
other amounts payable to such Lender under this Agreement, and (vi) the parties to each such
assignment shall execute and deliver to the Agent, for its acceptance and recording in the
Register, an Assignment and Acceptance, together with any Note subject to such assignment and a
processing and recordation fee of $3,500 payable by the parties to each such assignment,
provided, however, that in the case of each assignment made as a result of a demand
by the Borrower, such recordation fee shall be payable by the Borrower except that no such
recordation fee shall be payable in the case of an assignment made at the request of the Borrower
to an Eligible Assignee that is an existing Lender; provided, further, that the
Agent may, in its sole discretion, elect to waive such processing and recordation fee in the case
of any assignment, and (vii) any Lender may, without the approval of the Borrower and the Agent,
assign all or a portion of its rights to any Lender or to any of its or their Affiliates that is
not a natural person. Upon such execution, delivery, acceptance and recording, from and after the
effective date specified in each Assignment and Acceptance, (x) the assignee thereunder shall be a
party hereto and, to the extent that rights and obligations hereunder have been
 assigned to it
pursuant to such Assignment and Acceptance, have the rights and obligations of a Lender hereunder
and (y) the Lender assignor thereunder shall, to the extent that rights and obligations hereunder
have been assigned by it pursuant to such Assignment and Acceptance, relinquish its rights (other
than its rights under Sections 2.11, 2.14 and 8.04 to the extent any claim thereunder relates to an
event arising prior to such assignment) and be released from its obligations (other than its
obligations under Section 7.05 to the extent any claim thereunder relates to an event arising prior
to such assignment and under Section 8.08) under this Agreement (and, in the case of an Assignment
and Acceptance covering all or the remaining portion of an assigning Lender’s rights and
obligations under this Agreement, such Lender shall cease to be a party hereto). For the avoidance
of doubt, no assignment by an Issuing Bank pursuant to this Section 8.07(a) shall affect its rights
and obligations in its capacity as an Issuing Bank with respect to any Letters of Credit issued by
it and then outstanding.

          (b) By executing and delivering an Assignment and Acceptance, the Lender assignor thereunder
and the assignee thereunder confirm to and agree with each other and the other parties hereto

48

 

as follows: (i) other than as provided in such Assignment and Acceptance, such assigning
Lender makes no representation or warranty and assumes no responsibility with respect to any
statements, warranties or representations made in or in connection with this Agreement or the
execution, legality, validity, enforceability, genuineness, sufficiency or value of, or the
perfection or priority of any lien or security interest created or purported to be created under or
in connection with, this Agreement or any other instrument or document furnished pursuant hereto;
(ii) such assigning Lender makes no representation or warranty and assumes no responsibility with
respect to the financial condition of the Borrower or the performance or observance by the Borrower
of any of its obligations under this Agreement or any other instrument or document furnished
pursuant hereto; (iii) such assignee confirms that it has received a copy of this Agreement,
together with copies of the financial statements referred to in Section 4.01 and such other
documents and information as it has deemed appropriate to make its own credit analysis and decision
to enter into such Assignment and Acceptance; (iv) such assignee will, independently and without
reliance upon the Agent, such assigning Lender or any other Lender and based on such documents and
information as it shall deem appropriate at the time, continue to make its own credit decisions in
taking or not taking action under this Agreement; (v) such assignee confirms that it is an Eligible
Assignee; (vi) such assignee appoints and authorizes the Agent to take such action as agent on its
behalf and to exercise such powers and discretion under this Agreement as are delegated to the
Agent by the terms hereof, together with such powers and discretion as are reasonably incidental
thereto; and (vii) such assignee agrees that it will perform in accordance with their terms all of
the obligations that by the terms of this Agreement are required to be performed by it as a Lender.
Any assignment or transfer by a Lender of rights or obligations under this Agreement that does not
comply with subsection (a) and (b) of this Section 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 (e) of this Section.

          (c) Upon its receipt of an Assignment and Acceptance executed by an assigning Lender and an
assignee representing that it is an Eligible Assignee, together with any Note or Notes subject to
such assignment, the Agent shall, if such Assignment and Acceptance has been completed and is in
substantially the form of Exhibit C hereto, (i) accept such Assignment and Acceptance, (ii)
record the information contained therein in the Register and (iii) give prompt notice thereof to
the Borrower.

          (d) The Agent shall maintain at its address referred to in Section 8.02 a copy of each
Assumption Agreement and each Assignment and Acceptance delivered to and accepted by it and a
register for the recordation of the names and addresses of the Lenders and the Commitment of, and
principal amount of the Advances owing to, each Lender from time to time (the “Register”).
The entries in the Register shall be conclusive and binding for all purposes, absent manifest
error, and the Borrower, the Agent and the Lenders may treat each Person whose name is recorded in
the Register as a Lender hereunder for all purposes of this Agreement. The Register shall be
available for inspection by the Borrower or any Lender at any reasonable time and from time to time
upon reasonable prior notice.

          (e) Each Lender may sell participations to one or more banks or other entities (other than the
Borrower or any of its Affiliates) in or to all or a portion of its rights and/or obligations under
this Agreement (including, without limitation, all or a portion of its Commitment, the Advances
owing to it and any Note or Notes held by it); provided, however, that (i) such
Lender’s obligations under this Agreement (including, without limitation, its Commitment to the
Borrower hereunder) shall remain unchanged, (ii) such Lender shall remain solely responsible to the
other parties hereto for the performance of such obligations, (iii) such Lender shall remain the
holder of any such Note for all purposes of this Agreement, (iv) the Borrower, the Agent and the
other Lenders shall continue to deal solely and directly with such Lender in connection with such
Lender’s rights and obligations under this Agreement and (v) 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

49

 

interest on, the Notes 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, the Notes or any fees or other amounts payable hereunder, in each case to the
extent subject to such participation.

          (f) Any Lender may, in connection with any assignment or participation or proposed assignment
or participation pursuant to this Section 8.07, disclose to the assignee or participant or proposed
assignee or participant, any information relating to the Borrower furnished to such Lender by or on
behalf of the Borrower; provided that, prior to any such disclosure, the assignee or
participant or proposed assignee or participant shall agree to preserve the confidentiality of any
Borrower Information relating to the Borrower received by it from such Lender as provided in
Section 8.08.

          (g) Notwithstanding anything to the contrary contained herein, any Lender (a “Granting
Bank”) may grant to a special purpose funding vehicle (a “SPC”), identified as such in
writing from time to time by the Granting Bank to the Agent and the Borrower, the option to provide
to the Borrower all or any part of any Advance that such Granting Bank would otherwise be obligated
to make to the Borrower pursuant to this Agreement; provided that (i) nothing herein shall
constitute a commitment by any SPC to make any Advance, (ii) if an SPC elects not to exercise such
option or otherwise fails to provide all or any part of such Advance, the Granting Bank shall be
obligated, as a principal and not as a surety, to make such Advance pursuant to the terms hereof
and (iii) all voting rights under this Agreement, except with respect to the consent contemplated
in the last sentence of this Section 8.07(g), shall be exercised by the Granting Bank, all payments
hereunder shall continue to be made to the Granting Bank as agent for its SPC and the Granting Bank
will continue to be the sole Lender for all purposes of this Agreement except as expressly provided
in this Section 8.07(g). The making of an Advance by an SPC hereunder shall utilize the Commitment
of the Granting Bank to the same extent, and as if, such Advance were made by such Granting Bank.
Each party hereto hereby agrees that no SPC shall be liable for any indemnity or similar payment
obligation under this Agreement (all liability for which shall remain with the Granting Bank). In
furtherance of the foregoing, each party hereto hereby agrees (which agreement shall survive the
termination of this Agreement) that, prior to the date that is one year and one day after the
payment in full of all outstanding commercial paper or other senior indebtedness of any SPC, it
will not institute against, or join any other person in instituting against, such SPC any
bankruptcy, reorganization, arrangement, insolvency or liquidation proceedings under the laws of
the United States or any State thereof. In addition, notwithstanding anything to the contrary
contained in this Section 8.07, any SPC may (i) with notice to, but without the prior written
consent of, the Borrower and the Agent and without paying any processing fee therefor, assign all
or a portion of its interests in any Advances to the Granting Bank or to any financial institutions
(consented to by the Borrower and Agent) providing liquidity and/or credit support to or for the
account of such SPC to support the funding or maintenance of Advances and (ii) disclose on a
confidential basis any non-public information relating to its Advances to any rating agency,
commercial paper dealer or provider of any surety, guarantee or credit or liquidity enhancement to
such SPC. Notwithstanding the foregoing, neither such grant made hereunder nor the holding of
interest hereunder by any SPC shall increase any of the Borrower’s obligations and/or liabilities
(including without limitation tax liabilities and other indemnities) which the Borrower has but for
such grant or holding of interest (“SPC Liabilities”) and the Granting Bank shall hold the
Borrower harmless and indemnify the Borrower from and against any and all SPC Liabilities. This
Section may not be amended without the written consent of each SPC affected thereby.

          (h) Notwithstanding any other provision set forth in this Agreement, any Lender may at any
time create a security interest in all or any portion of its rights under this Agreement
(including, without limitation, the Advances owing to it and any Note or Notes held by it) in favor
of any Federal Reserve Bank in accordance with Regulation A of the Board of Governors of the
Federal Reserve System.

50

 

          (i) 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 (e) of this Section and, to the extent expressly
contemplated hereby, the Agent, the Issuing Banks, the Lenders, their respective Affiliates or any
employees, officers, directors, agents or advisors of the foregoing) any legal or equitable right,
remedy or claim under or by reason of this Agreement.

          (j) The words “execution,” “signed,” “signature,” and words of like import in any Assignment
and Acceptance 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
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 (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 (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. Execution in Counterparts. This Agreement may be executed in any
number of counterparts and by different parties hereto in separate counterparts, each of which when
so executed shall be deemed to be an original and all of which taken together shall constitute one
and the same agreement. Delivery of an executed counterpart of a signature page to this Agreement
by facsimile 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 nonexclusive 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 Notes, 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

51

 

heard and determined in any such New York State court or, to the 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. No Liability of the Issuing Banks. The Borrower assumes all risks of
the acts or omissions of any beneficiary or transferee of any Letter of Credit with respect to its
use of such Letter of Credit. Neither an Issuing Bank nor any of its officers or directors shall
be liable or responsible for: (a) the use that may be made of any Letter of Credit or any acts or
omissions of any beneficiary or transferee in connection therewith; (b) the validity, sufficiency
or genuineness of documents, or of any endorsement thereon, even if such documents should prove to
be in any or all respects invalid, insufficient, fraudulent or forged; (c) payment by such Issuing
Bank against presentation of documents that do not comply with the terms of a Letter of Credit,
including failure of any documents to bear any reference or adequate reference to the Letter of
Credit; or (d) any other circumstances whatsoever in making or failing to make payment under any
Letter of Credit, except that the Borrower shall have a claim against such Issuing Bank, and such
Issuing Bank shall be liable to the Borrower, to the extent of any direct, but not consequential,
damages suffered by the Borrower that the Borrower proves were caused by (i) such Issuing Bank’s
willful misconduct or gross negligence as determined in a final, non-appealable judgment by a court
of competent jurisdiction in determining whether documents presented under any Letter of Credit
comply with the terms of such Letter of Credit or (ii) such Issuing Bank’s willful failure to make
lawful payment under a Letter of Credit after the presentation to it of a draft and certificates
strictly complying with the terms and conditions of the Letter of Credit. In furtherance and not
in limitation of the foregoing, such Issuing Bank may accept documents that appear on their face to
be in order, without responsibility for further investigation, regardless of any notice or
information to the contrary.

          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 OR THE
NOTES 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 therewith

52

 

(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 and the Arranger, 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,
the Agent and the Arranger each 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 the 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 the Arranger has advised or is currently advising the
Borrower or any of its Affiliates on other matters) and neither the Agent nor the 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 and the
Arranger 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 the Arranger has any obligation to disclose any of such interests by virtue of any advisory,
agency or fiduciary relationship; and (v) the Agent and the 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 the Arranger
with respect to any breach or alleged breach of agency or fiduciary duty in connection with the
Loan Documents.

53

          FOR VALUE RECEIVED, the undersigned, ARIZONA PUBLIC SERVICE COMPANY, an Arizona corporation
(the “Borrower”), hereby promises to pay to the order of                                          or its
registered assigns (the “Lender”), in accordance with the provisions of the Credit
Agreement (as hereinafter defined), the principal amount of each Advance from time to time made by
the Lender to the Borrower pursuant to the Five-Year Credit Agreement dated as of September 28,
2006 among the Borrower, the Lender and certain other lenders parties thereto, the Arrangers, and
Bank of America, N.A., as Agent for the Lender and such other lenders, and the issuing banks and
other agents 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
payable at such times, as are specified in the Credit Agreement.

          Both principal and interest are payable in lawful money of the United States of America to the
Agent for the account of the Lender in same day funds at the address and account specified on
Schedule 8.02. Each Advance owing to the Lender by the Borrower pursuant to the Credit
Agreement, and all payments made on account of principal thereof, shall be recorded by the Lender
and, prior to any transfer hereof, endorsed on the grid attached hereto which is part of this
Promissory Note.

          This Promissory Note is one of the Notes referred to in, and is entitled to the benefits of,
the Credit Agreement. The Credit Agreement, among other things, (i) provides for the making of
Advances by the Lender to the Borrower from time to time in an aggregate amount not to exceed at
any time the Lender’s Unused Commitment, the indebtedness of the Borrower resulting from each such
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.
