agencies, or other rating agency, shall be deemed to have established a rating in the same Category
as such agency or agencies; (ii) if only two of Moody’s, S&P and Fitch shall have in effect a
rating for the Index Debt, and such ratings shall fall within different Categories, the Applicable
Rate shall be based on the higher of the two ratings; (iii) if each of Moody’s, S&P and Fitch shall
have in effect a rating for the Index Debt, and such ratings shall fall within different
Categories, the Applicable Rate shall be based on (x) the majority rating, if two of such ratings

different Categories, (iv) if the ratings established or deemed to have been established by
Moody’s, S&P and/or Fitch for the Index Debt shall be changed (other than as a result of a change

shall apply during the period commencing on the effective date of such change and ending on the
date immediately preceding the effective date of the next such change.

debt obligations, the Borrower and the Lenders shall negotiate in good faith to amend this
definition to reflect such changed rating system or the unavailability of ratings from such rating

Availability Period in an aggregate principal amount that will not result in (i) such Lender’s
Revolving Credit Exposure exceeding such Lender’s Revolving Credit Commitment or (ii) the sum of
the total Revolving Credit Exposures exceeding the total Revolving Credit Commitments. Within the
foregoing limits and subject to the terms and conditions set forth herein, the Borrower may borrow,

     (b) The Borrower shall have the right, without the consent of the Lenders but with the prior
approval of the Administrative Agent, not to be unreasonably withheld, to cause from time to time
an increase in the total Revolving Credit Commitments of the Lenders by adding to this Agreement
one or more additional Lenders or by allowing one or more Lenders to increase their respective
Revolving Credit Commitments; provided however (i) no Event of Default shall have

Administrative Agent no earlier than 30 days prior to the first anniversary of the Effective Date
and no later than 30 days prior to the Revolving Credit Maturity Date and Term

failure of any Lender to make any Loan required to be made by it shall not relieve any other Lender
of its obligations hereunder; provided that the Revolving Credit Commitments and
Term Loan Commitments of the Lenders are several and no Lender shall be responsible for any other
Lender’s failure to make Loans as required.

     (b) Subject to Section 2.14, each Revolving Borrowing and each Term Loan Borrowing shall be

herewith. Each Swingline Loan shall be an LMIR Loan. Each Lender at its option may make any
Eurodollar Loan by causing any domestic or foreign branch or Affiliate of such Lender to make such
Loan; provided that any exercise of such option shall not affect the obligation of
the Borrower to repay such Loan in accordance with the terms of this Agreement.

     (c) At the commencement of each Interest Period for any Eurodollar Revolving Borrowing or
Eurodollar Term Loan Borrowing, such Borrowing shall be in an aggregate amount that is an integral

of a credit to the general deposit account of the Borrower with the Swingline Lender (or, in the
case of a Swingline Loan made to finance the reimbursement of an LC Disbursement as provided in
Section 2.06(e), by remittance to the Issuing Bank) by 3:00 p.m., New York City time, on the
requested date of such Swingline Loan.

withholding or reduction whatsoever. Each Lender shall comply with its obligation under this
paragraph by wire transfer of immediately available funds, in the same manner as provided in

mutatis mutandis, to the payment obligations of the Lenders), and the
Administrative Agent shall promptly pay to the Swingline Lender the amounts so received by it from
the Lenders. The Administrative Agent shall notify the Borrower of any participations in any
Swingline Loan acquired pursuant to this paragraph, and thereafter payments in respect of such
Swingline Loan shall be made to the Administrative Agent and not to the Swingline Lender. Any
amounts received by the Swingline Lender from the Borrower (or other party on behalf of the
Borrower) in respect of a Swingline Loan after receipt by the Swingline Lender of the proceeds of a
sale of participations therein shall be promptly remitted to the Administrative Agent; any such
amounts received by the Administrative Agent shall be promptly remitted by the Administrative Agent
to the Lenders that shall have made their payments pursuant to this paragraph and to the Swingline
Lender, as their interests may appear. The purchase of participations in a Swingline Loan pursuant

any request for a Letter of Credit. A Letter of Credit shall be issued, amended, renewed or
extended if and only if (and upon issuance, amendment, renewal or extension of each Letter of

potential Fronting Exposure with respect to such Defaulting Lender arising from either the Letter
of Credit then proposed to be issued or that Letter of Credit and all other LC Exposure as to which
Issuing Banks have actual or potential Fronting Exposure, has been fully reallocated pursuant to
Section 2.21(a)(iv) or cash collateralized pursuant to Section 2.06(j), or (ii) such Issuing Bank
has entered into other arrangements satisfactory to the Issuing Bank (in its sole discretion) with
the Borrower or such Defaulting Lender to eliminate such actual or potential Fronting Exposure, as
such Issuing Bank may elect in its sole discretion.

     (c) Expiration Date. Each Letter of Credit shall expire at or prior to the close of
business on the earlier of (i) the date one year after the date of the issuance of such Letter of
Credit (or, in the case of any renewal or extension thereof, one year after such renewal or
extension) and (ii) the date that is five Business Days prior to the Revolving Credit Maturity
Date; provided, if the Borrower so requests, the Issuing Bank may, in its sole and absolute
discretion, agree to issue a Letter of Credit that has automatic renewal provisions (each, an
“Auto-Renewal Letter of Credit”); provided that any such Auto-Renewal Letter of
Credit must permit the Issuing Bank to prevent any such renewal at least once in each twelve-month
period (commencing with the date of issuance of such Letter of Credit) by giving prior notice to
the
beneficiary thereof not later than (A) thirty (30) days before the end of such twelve-month
period, or (B) such later date to be agreed upon at the time such Letter of Credit is issued (the
“Nonrenewal Notice Date”). Once an Auto-Renewal Letter of Credit has been issued, the
Lenders shall be deemed to have authorized (but may not require) the Issuing Bank to permit the
renewal of such Letter of Credit at any time prior to the date set forth in clause (ii) of this
Section 2.06(c); provided that the expiry date of such Letter of Credit complies with clause (ii)
of this Section 2.06(c).

     (d) 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
Issuing Bank or the Lenders, the Issuing Bank hereby grants to each Lender, and each Lender hereby

27

 

acquires from the Issuing Bank, a participation in such Letter of Credit equal to such Lender’s
Applicable Revolving Credit Percentage of the aggregate amount available to be drawn under such
Letter of Credit. In consideration and in furtherance of the foregoing, each Lender hereby
absolutely and unconditionally agrees to pay to the Administrative Agent, for the account of the
Issuing Bank, such Lender’s Applicable Revolving Credit Percentage of each LC Disbursement made by
the Issuing Bank and not reimbursed by the Borrower on the date due as provided in paragraph (e) of
this Section, or of any reimbursement payment required to be refunded to the Borrower for any
reason. 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 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.

Letter of Credit, the Borrower shall reimburse such LC Disbursement by paying to the Administrative
Agent an amount equal to such LC Disbursement not later than 12:00 noon, New York City time, on the
date that such LC Disbursement is made, if the Borrower shall have received notice of such LC
Disbursement prior to 10:00 a.m., New York City time, on such date, or, if such notice has not been
received by the Borrower prior to such time on such date, then not later than 12:00 noon, New York
City time, on the Business Day immediately following the day that the Borrower receives such

the Borrower’s obligation to make such payment shall be discharged and replaced by the resulting
ABR Revolving Borrowing or Swingline Loan. If the Borrower fails to make such payment when due,
the Administrative Agent shall notify each Lender of the applicable LC Disbursement, the payment
then due from the Borrower in respect thereof and such Lender’s Applicable Revolving Credit
Percentage thereof. Promptly following receipt of such notice, each Lender shall pay to the
Administrative Agent its Applicable Revolving Credit Percentage of the payment then due from the
Borrower, in the same manner as provided in Section 2.07 with respect to Loans made by such Lender
(and Section 2.07 shall apply, mutatis mutandis, to the payment obligations of the
Lenders), and the Administrative Agent shall promptly pay to the Issuing Bank the amounts so
received by it from the Lenders. Promptly following receipt by the Administrative Agent of any
payment from the Borrower pursuant to this paragraph, the Administrative Agent shall distribute
such payment to the Issuing Bank or, to the extent that Lenders have made payments pursuant to this
paragraph to reimburse the Issuing
Bank, then to such Lenders and the Issuing Bank as their interests may appear. Any payment
made by a Lender pursuant to this paragraph to reimburse the Issuing Bank for any LC Disbursement
(other than the funding of ABR Revolving Loans or a Swingline Loan as contemplated above) shall not
constitute a Loan and shall not relieve the Borrower of its obligation to reimburse such LC
Disbursement.

     (f) Obligations Absolute. The Borrower’s obligation to reimburse LC Disbursements as
provided in paragraph (e) of this Section shall be absolute, unconditional and irrevocable, and
shall be performed strictly in accordance with the terms of this Agreement under any and all
circumstances whatsoever and irrespective of (i) any lack of validity or enforceability of any
Letter of Credit or this Agreement, or any term or provision therein, (ii) any draft or other

28

 

document presented under a Letter of Credit proving to be forged, fraudulent or invalid in any
respect or any statement therein being untrue or inaccurate in any respect, (iii) payment by the
Issuing Bank under a Letter of Credit against presentation of a draft or other document that does
not comply with the terms of such Letter of Credit, or (iv) any other event or circumstance
whatsoever, whether or not similar to any of the foregoing, that might, but for the provisions of
this Section, constitute a legal or equitable discharge of, or provide a right of setoff against,
the Borrower’s obligations hereunder. Neither the Administrative Agent, the Lenders nor the
Issuing Bank, nor any of their Related Parties, shall have any liability or responsibility by
reason of or in connection with the issuance or transfer of any Letter of Credit or any payment or
failure to make any payment thereunder (irrespective of any of the circumstances referred to in the
preceding sentence), or any error, omission, interruption, loss or delay in transmission or
delivery of any draft, notice or other communication under or relating to any Letter of Credit
(including any document required to make a drawing thereunder), any error in interpretation of
technical terms or any consequence arising from causes beyond the control of the Issuing Bank;
provided that the foregoing shall not be construed to excuse the Issuing Bank from
liability to the Borrower to the extent of any direct damages (as opposed to consequential damages,
claims in respect of which are hereby waived by the Borrower to the extent permitted by applicable
law) suffered by the Borrower that are caused by the Issuing Bank’s failure to exercise care when
determining whether drafts and other documents presented under a Letter of Credit comply with the
terms thereof. The parties hereto expressly agree that, in the absence of gross negligence or
willful misconduct on the part of the Issuing Bank (as finally determined by a court of competent
jurisdiction), the Issuing Bank shall be deemed to have exercised care in each such determination.
In furtherance of the foregoing and without limiting the generality thereof, the parties agree
that, with respect to documents presented which appear on their face to be in substantial
compliance with the terms of a Letter of Credit, the Issuing Bank may, in its sole discretion,
either accept and make payment upon such documents without responsibility for further
investigation, regardless of any notice or information to the contrary, or refuse to accept and
make payment upon such documents if such documents are not in strict compliance with the terms of
such Letter of Credit.

     (g) Disbursement Procedures. The Issuing Bank shall, promptly following its receipt
thereof, examine all documents purporting to represent a demand for payment under a Letter of
Credit. The Issuing Bank shall promptly notify the Administrative Agent and the Borrower by
telephone (confirmed by telecopy) of such demand for payment and whether the Issuing Bank has made
or will make an LC Disbursement thereunder; provided that any failure to give or
delay in giving such notice shall not relieve the Borrower of its obligation to reimburse the
Issuing Bank and the Lenders with respect to any such LC Disbursement.

     (h) Interim Interest. If the Issuing Bank shall make any LC Disbursement, then,
unless the Borrower shall reimburse such LC Disbursement in full on the date such LC Disbursement
is made, the unpaid amount thereof shall bear interest, for each day from and including the date
such LC Disbursement is made to but excluding the date that the Borrower reimburses such LC
Disbursement, at the rate per annum then applicable to ABR Revolving Loans; provided
that, if the Borrower fails to reimburse such LC Disbursement when due pursuant to
paragraph (e) of this Section, then Section 2.13(d) shall apply. Interest accrued pursuant to this
paragraph shall be for the account of the Issuing Bank, except that interest accrued on and after
the date of payment by any Lender pursuant to paragraph (e) of this Section

29

 

to reimburse the
Issuing Bank shall be for the account of such Lender to the extent of such payment.

     (i) Replacement of the Issuing Bank. The Issuing Bank may be replaced at any time by
written agreement among the Borrower, the Administrative Agent, the replaced Issuing Bank and the
successor Issuing Bank. The Administrative Agent shall notify the Lenders of any such replacement
of the Issuing Bank. At the time any such replacement shall become effective, the Borrower shall
pay all unpaid fees accrued for the account of the replaced Issuing Bank pursuant to Section
2.12(b). From and after the effective date of any such replacement, (i) the successor Issuing Bank
shall have all the rights and obligations of the Issuing Bank under this Agreement with respect to
Letters of Credit to be issued thereafter and (ii) references herein to the term “Issuing Bank”
shall be deemed to refer to such successor or to any previous Issuing Bank, or to such successor
and all previous Issuing Banks, as the context shall require. After the replacement of an Issuing
Bank hereunder, the replaced Issuing Bank shall remain a party hereto and shall continue to have
all the rights and obligations of an Issuing Bank under this Agreement with respect to Letters of
Credit issued by it prior to such replacement, but shall not be required to issue additional
Letters of Credit.

     (j) Cash Collateralization. If any Event of Default shall occur and be continuing and
if the maturity of the Loans has been accelerated pursuant to Article VII, on the Business Day that
the Borrower receives notice from the Administrative Agent upon written request of the Required
Revolving Lenders demanding the deposit of cash collateral pursuant to this paragraph, the Borrower
shall deposit in an account with the Administrative Agent, in the name of the Administrative Agent
and for the benefit of the Lenders, an amount in cash equal to the LC Exposure as of such date plus
any accrued and unpaid interest thereon; provided that the obligation to deposit
such cash collateral shall become effective immediately, and such deposit shall become immediately
due and payable, without demand or other notice of any kind, upon the occurrence of any Event of
Default with respect to the Borrower described in clause (g) or (h) of Article VII.. In addition,
at any time that there shall exist a Defaulting Lender, if the Fronting Exposure with respect to
such Defaulting Lender has not been fully reallocated pursuant to Section 2.21(a)(iv), immediately
upon the request of the Administrative Agent, the Issuing Bank or the Swingline Lender with respect
to any such unallocated Fronting Exposure, deposit in an account with the Administrative Agent, in
the name of the Administrative Agent and for the benefit of the Lenders, an amount in cash equal to
such unallocated Fronting Exposure. Such deposits shall be held by the Administrative Agent as
collateral for the payment and performance of the obligations of the Borrower under this Agreement.
The Administrative Agent shall have exclusive dominion and control, including the exclusive right
of withdrawal, over such account. Other than any interest earned on the investment of such
deposits, which investments shall be made at the option and sole discretion of the Administrative
Agent and at
the Borrower’s risk and expense, such deposits shall not bear interest. Interest or profits,
if any, on such investments shall accumulate in such account. Moneys in such account shall be
applied by the Administrative Agent to reimburse the Issuing Bank for LC Disbursements for which it
has not been reimbursed (or, as to cash collateral with respect to Fronting Exposure relating to a
Defaulting Lender’s Swingline Exposure, to reimburse the Swingline Lender for Swingline Loans which
have not been repaid) and, to the extent not so applied, shall be held for the satisfaction of the
reimbursement obligations of the Borrower for the LC Exposure (or such Fronting Exposure) at such
time or, if the maturity of the Loans has been accelerated (but subject to the consent of Lenders
with LC Exposure representing greater than 51% of the total LC

30

 

Exposure), be applied to satisfy
other obligations of the Borrower under this Agreement. If the Borrower is required to provide an
amount of cash collateral hereunder as a result of the occurrence of an Event of Default, such
amount (to the extent not applied as aforesaid) shall be returned to the Borrower within three
Business Days after all Events of Default have been cured or waived.

     SECTION 2.07. Funding of Borrowings. (a) Each Lender shall make each Loan to be
made by it hereunder on the proposed date thereof by wire transfer of immediately available funds
by 1:00 p.m., New York City time, to the account of the Administrative Agent most recently
designated by it for such purpose by notice to the Lenders; provided that Swingline
Loans shall be made as provided in Section 2.05. The Administrative Agent will make such Loans
available to the Borrower by promptly crediting the amounts so received, in like funds, to an
account designated by the Borrower in the applicable Borrowing Request; provided
that ABR Revolving Loans made to finance the reimbursement of an LC Disbursement as
provided in Section 2.06(e) shall be remitted by the Administrative Agent to the Issuing Bank.

     (b) Unless the Administrative Agent shall have received notice from a Lender prior to the
proposed date of any Borrowing that such Lender will not make available to the Administrative Agent
such Lender’s share of such Borrowing, the Administrative Agent may assume that such Lender has
made such share available on such date in accordance with paragraph (a) of this Section and may, in
reliance upon such assumption, make available to the Borrower a corresponding amount. In such
event, if a Lender has not in fact made its share of the applicable Borrowing available to the
Administrative Agent, then the applicable Lender and the Borrower severally agree to pay to the
Administrative Agent forthwith on demand such corresponding amount with interest thereon, for each
day from and including the date such amount is made available to the Borrower to but excluding the
date of payment to the Administrative Agent, at (i) in the case of such Lender, the greater of the
Federal Funds Effective Rate and a rate determined by the Administrative Agent in accordance with
banking industry rules on interbank compensation or (ii) in the case of the Borrower, the interest
rate applicable to such Borrowing. If such Lender pays such amount to the Administrative Agent,
then such amount shall constitute such Lender’s Loan included in such Borrowing.

     SECTION 2.08. Interest Elections. (a) Each Revolving Borrowing and the Term
Borrowing initially shall be of the Type specified in the applicable Borrowing Request and, in the
case of a Eurodollar Revolving Borrowing or Eurodollar Term Loan Borrowing, shall have an initial
Interest Period as specified in such Borrowing Request. Thereafter, the Borrower may elect to
convert such Borrowing to a different Type or to continue such Borrowing and, in the case of a
Eurodollar Revolving
Borrowing or Eurodollar Term Loan Borrowing, may elect Interest Periods therefor, all as
provided in this Section. The Borrower may elect different options with respect to different
portions of the affected Borrowing, in which case each such portion shall be allocated ratably
among the Lenders holding the Loans comprising such Borrowing, and the Loans comprising each such
portion shall be considered a separate Borrowing. This Section shall not apply to Swingline
Borrowings, which may not be converted or continued.

     (b) To make an election pursuant to this Section, the Borrower shall notify the Administrative
Agent of such election by telephone by the time that a Borrowing Request would be required under
Section 2.03 if the Borrower were requesting a Revolving Borrowing or Term Loan Borrowing of the
Type resulting from such election to be made on the effective date of

31

 

such election. Each such
telephonic Interest Election Request shall be irrevocable and shall be confirmed promptly by hand
delivery or telecopy to the Administrative Agent of a written Interest Election Request signed by
the Borrower.

     (c) Each telephonic and written Interest Election Request shall specify the following
information in compliance with Section 2.02:

     (i) the Borrowing to which such Interest Election Request applies and, if different
options are being elected with respect to different portions thereof, the portions thereof
to be allocated to each resulting Borrowing (in which case the information to be specified
pursuant to clauses (iii) and (iv) below shall be specified for each resulting Borrowing);

     (ii) the effective date of the election made pursuant to such Interest Election
Request, which shall be a Business Day;

     (iii) whether the resulting Borrowing is to be an ABR Borrowing or a Eurodollar
Borrowing; and

     (iv) if the resulting Borrowing is a Eurodollar Borrowing, the Interest Period to be
applicable thereto after giving effect to such election, which shall be a period
contemplated by the definition of the term “Interest Period”.

If any such Interest Election Request requests a Eurodollar Borrowing but does not specify an
Interest Period, then the Borrower shall be deemed to have selected an Interest Period of one
month’s duration, in the case of a Eurodollar Borrowing.

     (d) Promptly following receipt of an Interest Election Request, the Administrative Agent shall
advise each Lender of the details thereof and of such Lender’s portion of each resulting Borrowing.

     (e) If the Borrower fails to deliver a timely Interest Election Request with respect to a
Eurodollar Revolving Borrowing or Eurodollar Term Loan Borrowing prior to the end of the Interest
Period applicable thereto, then, unless such Borrowing is repaid as provided herein, at the end of
such Interest Period such Borrowing shall be converted to an ABR Borrowing. Notwithstanding any
contrary provision hereof, if an Event of Default has occurred and is continuing and the
Administrative Agent, at the request of the Required Lenders, so notifies the Borrower, then, so
long as an Event of Default is continuing (i) no outstanding Revolving
Borrowing or Term Loan Borrowing may be converted to or continued as a Eurodollar Borrowing
and (ii) unless repaid, each Eurodollar Revolving Borrowing and each Eurodollar Term Loan Borrowing
shall be converted to an ABR Borrowing at the end of the Interest Period applicable thereto.

     SECTION 2.09. Termination and Reduction of Revolving Credit Commitments. (a) Unless
previously terminated, the Revolving Credit Commitments shall terminate on the Revolving Credit
Maturity Date.

     (b) The Borrower may at any time terminate, or from time to time reduce, the Revolving Credit
Commitments; provided that (i) each reduction of the Revolving Credit

32

 

Commitments
shall be in an amount that is an integral multiple of $1,000,000 and not less than $5,000,000 and
(ii) the Borrower shall not terminate or reduce the Revolving Credit Commitments if, after giving
effect to any concurrent prepayment of the Loans in accordance with Section 2.11, the sum of the
Revolving Credit Exposures would exceed the total Revolving Credit Commitments.

     (c) The Borrower shall notify the Administrative Agent of any election to terminate or reduce
the Revolving Credit Commitments under paragraph (b) of this Section at least three Business Days
prior to the effective date of such termination or reduction, specifying such election and the
effective date thereof. Promptly following receipt of any notice, the Administrative Agent shall
advise the Lenders of the contents thereof. Each notice delivered by the Borrower pursuant to this
Section shall be irrevocable; provided that a notice of termination of the
Revolving Credit Commitments delivered by the Borrower may state that such notice is conditioned
upon the effectiveness of other credit facilities, in which case such notice may be revoked by the
Borrower (by notice to the Administrative Agent on or prior to the specified effective date) if
such condition is not satisfied. Any termination or reduction of the Revolving Credit Commitments
shall be permanent. Each reduction of the Revolving Credit Commitments shall be made ratably among
the Lenders in accordance with their respective Revolving Credit Commitments.

     SECTION 2.10. Repayment of Loans; Evidence of Debt. (a) The Borrower hereby
unconditionally promises to pay (i) to the Administrative Agent for the account of each Lender the
then unpaid principal amount of each Revolving Loan on the Revolving Credit Maturity Date, (ii) to
the Swingline Lender the then unpaid principal amount of each Swingline Loan on the earlier of the
Revolving Credit Maturity Date and a date that is not more than fourteen Business Days after such
Swingline Loan is made; provided that on each date that a Revolving Borrowing is
made, the Borrower shall repay all Swingline Loans then outstanding and (iii) to the Administrative
Agent for the account of each Lender the then unpaid principal amount of each Term Loan on the Term
Loan Maturity Date.

     (b) 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 Loan made by such
Lender, including the amounts of principal and interest payable and paid to such Lender from time
to time hereunder.

     (c) The Administrative Agent shall maintain accounts in which it shall record (i) the amount
of each Loan made hereunder, the Class and Type thereof and the Interest Period applicable thereto,
(ii) the amount of any principal or interest due and payable or to become due and payable from the
Borrower to each Lender hereunder and (iii) the amount of any sum received by the Administrative
Agent hereunder for the account of the Lenders and each Lender’s share thereof.

     (d) The entries made in the accounts maintained pursuant to paragraph (b) or (c) of this
Section shall be prima facie evidence of the existence and amounts of the
obligations recorded therein; provided that the failure of any Lender or the
Administrative Agent to maintain such accounts or any error therein shall not in any manner affect
the obligation of the Borrower to repay the Loans in accordance with the terms of this Agreement.

33

 

     (e) Any Lender may request that Loans made by it be evidenced by a promissory note. In such
event, the Borrower shall prepare, execute and deliver to such Lender a promissory note payable to
the order of such Lender (or, if requested by such Lender, to such Lender and its registered
assigns) and substantially in the form of (i) with respect to Revolving Loans, in the form of
revolving loan note attached hereto as Exhibit F-1, (ii) with respect to Term Loans, in the form of
term loan note attached hereto as Exhibit F-2 and (ii) with respect to Swingline Loans, in the form
of swingline loan note attached hereto as Exhibit F-3. Thereafter, the Loans evidenced by such
promissory note and interest thereon shall at all times (including after assignment pursuant to
Section 9.04) be represented by one or more promissory notes in such form payable to the order of
the payee named therein (or, if such promissory note is a registered note, to such payee and its
registered assigns).

     SECTION 2.11. Prepayment of Loans. (a) The Borrower shall have the right at any
time and from time to time to prepay any Borrowing in whole or in part, subject to prior notice in
accordance with paragraph (b) of this Section.

     (b) The Borrower shall notify the Administrative Agent (and, in the case of prepayment of a
Swingline Loan, the Swingline Lender) by telephone (confirmed by telecopy) of any prepayment
hereunder (i) in the case of prepayment of a Eurodollar Revolving Borrowing, Eurodollar Term Loan
Borrower, ABR Revolving Borrowing or ABR Term Loan Borrowing, not later than 11:00 a.m., New York
City time, on the date of prepayment, or (ii) in the case of prepayment of a Swingline Loan, not
later than 12:00 noon, New York City time, on the date of prepayment. Each such notice shall be
irrevocable and shall specify the prepayment date and the principal amount of each Borrowing or
portion thereof to be prepaid; provided that, if a notice of prepayment is given in
connection with a conditional notice of termination of the Revolving Credit Commitments as
contemplated by Section 2.09, then such notice of prepayment may be revoked if such notice of
termination is revoked in accordance with Section 2.09. Promptly following receipt of any such
notice relating to a Revolving Borrowing or Term Loan Borrowing, the Administrative Agent shall
advise the Lenders of the contents thereof. Each partial prepayment of any Revolving Borrowing or
Term Loan Borrowing shall be in an amount that is an integral multiple of $1,000,000 and not less
than $1,000,000 in the case of an ABR Revolving Borrowing or ABR Term Loan Borrowing, or $3,000,000
in the case of a Eurodollar Revolving Borrowing or Eurodollar Term Loan Borrowing. Each prepayment
of a Revolving Borrowing or Term Loan Borrowing shall be applied ratably to the Loans included in
the prepaid
Borrowing. Prepayments shall be accompanied by accrued interest to the extent required by
Section 2.13.

     SECTION 2.12. Fees. (a) The Borrower agrees to pay to the Administrative Agent for
the account of each Lender a facility fee, which shall accrue at the Applicable Rate on the daily
amount of the Revolving Credit Commitment of such Lender (whether used or unused) during the period
from and including the Effective Date to but excluding the date on which such Revolving Credit
Commitment terminates; provided that, if such Lender continues to have any
Revolving Credit Exposure after its Revolving Credit Commitment terminates, then such facility fee
shall continue to accrue on the daily amount of such Lender’s Revolving Credit Exposure from and
including the date on which its Revolving Credit Commitment terminates to but excluding the date on
which such Lender ceases to have any Revolving Credit Exposure. Accrued facility fees shall be
payable in arrears on the last day of March, June, September and December of each year and on the
date on which the Revolving Credit Commitments terminate,

34

 

commencing on the first such date to
occur after the date hereof; provided that any facility fees accruing after the
date on which the Revolving Credit Commitments terminate shall be payable on demand. All facility
fees shall be computed on the basis of a year of 365 days (or 366 days in leap year) and shall be
payable for the actual number of days elapsed (including the first day but excluding the last day).

     (b) The Borrower agrees to pay (i) to the Administrative Agent for the account of each Lender
a participation fee with respect to its participations in Letters of Credit, which shall accrue at
the same Applicable Rate as interest on Eurodollar Revolving Loans on the average daily amount of
such Lender’s LC Exposure (excluding any portion thereof attributable to unreimbursed LC
Disbursements) during the period from and including the Effective Date to but excluding the date on
which such Lender ceases to have any LC Exposure, and (ii) to the Issuing Bank a fronting fee, at a
rate per annum agreed to between the Borrower and each Issuing Bank, which shall accrue on the
average daily amount of the LC Exposure with respect to Letters of Credit issued by such Issuing
Bank (excluding any portion thereof attributable to unreimbursed LC Disbursements) during the
period from and including the Effective Date to but excluding the date on which there ceases to be
any LC Exposure, as well as the Issuing Bank’s standard fees with respect to the issuance,
amendment, renewal or extension of any Letter of Credit issued by such Issuing Bank or processing
of drawings thereunder. Participation fees and fronting fees accrued through and including the
last day of March, June, September and December of each year shall be payable quarterly on the
third Business Day following the last day of March, June, September and December of each year,
commencing on the first such date to occur after the Effective Date; provided that
all such fees shall be payable on the date on which the Revolving Credit Commitments terminate and
any such fees accruing after the date on which the Revolving Credit Commitments terminate shall be
payable on demand. Any other fees payable to the Issuing Bank pursuant to this paragraph shall be
payable within 10 days after demand. All participation fees and fronting fees shall be computed on
the basis of a year of 365 days (or 366 days in leap year) and shall be payable for the actual
number of days elapsed (including the first day but excluding the last day).

     (c) The Borrower agrees to pay to the Administrative Agent, for its own account, fees payable
in the amounts and at the times separately agreed upon between the Borrower and the Administrative
Agent.

     (d) All fees payable hereunder shall be paid on the dates due, in immediately available funds,
to the Administrative Agent (or to the Issuing Bank, in the case of fees payable to it) for
distribution, in the case of facility fees and participation fees, to the Lenders. Fees paid shall
not be refundable under any circumstances.

     (e) If any Lender shall become a Defaulting Lender, then no facility fee under subsection (a)
of this Section 2.12 with respect to any unfunded portion of such Lender’s Revolving Credit
Commitment, nor any letter of credit fee under subsection (b) of this Section 2.12 shall accrue for
the account of such Lender from and after the date upon which such Lender shall have become a
Defaulting Lender until such time as such Lender is no longer a Defaulting Lender.

     SECTION 2.13. Interest. (a) The Loans comprising each ABR Revolving Borrowing or
ABR Term Loan Borrowing shall bear interest on each day at the Alternate Base Rate for such day
plus an amount equal to the “ABR Spread” set forth in the pricing grid set forth in the

35

 

defined
term “Applicable Rate” that would be applicable to ABR Revolving Loans or ABR Term Loans,
respectively, on such day. The Loans comprising each Swingline Loan shall bear interest on each
day at the LIBO Market Index Rate for such day plus an amount equal to the “Eurodollar
Spread” set forth in the pricing grid set forth in the defined term “Applicable Rate” that would be
applicable to Eurodollar Revolving Loans on such day.

     (b) The Loans comprising each Eurodollar Borrowing shall bear interest in the case of a
Eurodollar Revolving Loan or Eurodollar Term Loan, at the LIBO Rate for the Interest Period in
effect for such Borrowing plus the Applicable Rate for Eurodollar Revolving Loans or Eurodollar
Term Loans, respectively.

     (c) Notwithstanding the foregoing, if any principal of or interest on any Loan or any fee or
other amount payable by the Borrower hereunder is not paid when due, whether at stated maturity,
upon acceleration or otherwise, such overdue amount shall bear interest, after as well as before
judgment, at a rate per annum equal to (i) in the case of overdue principal of any Loan, 2% plus
the rate otherwise applicable to such Loan as provided in the preceding paragraphs of this Section
or (ii) in the case of any other amount, 2% plus the rate applicable to ABR Revolving Loans as
provided in paragraph (a) of this Section.

     (d) Accrued interest on each Loan shall be payable in arrears on each Interest Payment Date
for such Loan and, in the case of Revolving Loans, upon termination of the Revolving Credit
Commitments; provided that (i) interest accrued pursuant to paragraph (d) of this
Section shall be payable on demand, (ii) in the event of any repayment or prepayment of any Loan
(other than a prepayment of an ABR Revolving Loan prior to the end of the Availability Period),
accrued interest on the principal amount repaid or prepaid shall be payable on the date of such
repayment or prepayment and (iii) in the event of any conversion of any Eurodollar Revolving Loan
prior to the end of the current Interest Period therefor, accrued interest on such Loan shall be
payable on the effective date of such conversion.

     (e) All interest determined by reference to the LIBO Rate or clause (b) of the definition of
Alternate Base Rate shall be computed on the basis of a year of 360 days, and all other interest
shall be computed on the basis of a year of 365 days (or 366 days in a leap year), and in each case
shall be payable for the actual number of days elapsed (including the first day
but excluding the last day). The applicable Alternate Base Rate or LIBO Rate shall be
determined by the Administrative Agent, and such determination shall be conclusive absent manifest
error.

     (f) The Borrower shall pay to each Lender, so long as such Lender shall be required under
regulations of the Board to maintain reserves with respect to liabilities or assets consisting of
or including Eurocurrency Liabilities, additional interest on the unpaid principal amount of each
Borrowing of such Lender during such periods as such Borrowing is a Eurodollar Revolving Borrowing
or Eurodollar Term Loan Borrowing, from the date of such Borrowing until such principal amount is
paid in full, at an interest rate per annum equal at all times to the remainder obtained by
subtracting (i) the LIBO Rate for the Interest Period in effect for such Eurodollar Revolving
Borrowing or Eurodollar Term Loan Borrowing from (ii) the rate obtained by dividing such LIBO Rate
by a percentage equal to 100% minus the Eurodollar Rate Reserve Percentage of such Lender for such
Interest Period. Such additional interest shall be determined by such Lender. The Borrower shall
from time to time, within 15 days after demand (which demand shall be accompanied by a certificate
comporting with the requirements set forth in

36

 

Section 2.15(d)) by such Lender (with a copy of such
demand and certificate to the Administrative Agent) pay to the Lender giving such notice such
additional interest; provided, however, that the Borrower shall not be required to
pay to such Lender any portion of such additional interest that accrued more than 90 days prior to
any such demand, unless such additional interest was not determinable on the date that is 90 days
prior to such demand.

     SECTION 2.14. Alternate Rate of Interest. If prior to the commencement of any
Interest Period for a Eurodollar Borrowing:

     (a) the Administrative Agent determines (which determination shall be conclusive absent
manifest error) that adequate and reasonable means do not exist for ascertaining the LIBO
Rate, as applicable, for such Interest Period; or

     (b) the Administrative Agent is advised by the Required Lenders that the LIBO Rate for
such Interest Period will not adequately and fairly reflect the cost to such Lenders (or
Lender) of making or maintaining their Loans (or its Loan) included in such Borrowing for
such Interest Period;

then the Administrative Agent shall give notice thereof to the Borrower and the Lenders by
telephone or telecopy as promptly as practicable thereafter and, until the Administrative Agent
notifies the Borrower and the Lenders that the circumstances giving rise to such notice no longer
exist, (i) any Interest Election Request that requests the conversion of any Revolving Borrowing or
Term Loan Borrowing to, or continuation of any Revolving Borrowing or Term Loan Borrowing as, a
Eurodollar Borrowing shall be ineffective, and (ii) if any Borrowing Request requests a Eurodollar
Revolving Borrowing or Eurodollar Term Loan Borrowing, such Borrowing shall be made as an ABR
Borrowing; provided that if the circumstances giving rise to such notice affect
only one Type of Borrowings, then the other Type of Borrowings shall be permitted.

     SECTION 2.15. Illegality; Increased Costs. (a) If any Change in Law shall make it
unlawful or impossible for any Lender to make, maintain or fund its Eurodollar Loans, such Lender
shall so notify the
Administrative Agent. Upon receipt of such notice, the Administrative Agent shall immediately
give notice thereof to the other Lenders and to the Borrower, whereupon until such Lender notifies
the Borrower and the Administrative Agent that the circumstances giving rise to such suspension no
longer exist, the obligation of such Lender to make Eurodollar Loans shall be suspended. If such
Lender shall determine that it may not lawfully continue to maintain and fund any of its
outstanding Eurodollar Loans to maturity and shall so specify in such notice, the Borrower shall
immediately prepay (which prepayment shall not be subject to Section 2.11) in full the then
outstanding principal amount of such Eurodollar Loans, together with the accrued interest thereon.

     (b) If any Change in Law shall:

     (i) impose, modify or deem applicable any reserve, special deposit or similar
requirement against assets of, deposits with or for the account of, or credit extended by,
any Lender (except any such reserve requirement reflected in Section 2.13(f)) or the Issuing
Bank; or

37

 

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

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

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

     (d) A certificate of a Lender or the Issuing Bank setting forth, in reasonable detail showing
the computation thereof, the amount or amounts necessary to compensate such Lender or the Issuing
Bank or its holding company, as the case may be, as specified in paragraph (b) or (c) of this
Section shall be delivered to the Borrower and shall be conclusive absent manifest error. Such
certificate shall further certify that such Lender or the Issuing Bank is making similar demands of
its other similarly situated borrowers. The Borrower shall pay such Lender
or the Issuing Bank, as the case may be, the amount shown as due on any such certificate
within 10 days after receipt thereof, if such certificate complies herewith.

     (e) Failure or delay on the part of any Lender or the Issuing Bank to demand compensation
pursuant to this Section shall not constitute a waiver of such Lender’s or the Issuing Bank’s right
to demand such compensation; provided that the Borrower shall not be required to
compensate a Lender or the Issuing Bank pursuant to this Section for any increased costs or
reductions incurred more than 90 days prior to the date that such Lender or the Issuing Bank, as
the case may be, notifies the Borrower of the Change in Law giving rise to such increased costs or
reductions and of such Lender’s or the Issuing Bank’s intention to claim compensation therefor;
provided further that, if the Change in Law giving rise to such increased costs or
reductions is retroactive, then the 90-day period referred to above shall be extended to include
the period of retroactive effect thereof (to the extent that such period of retroactive effect is
not already included in such 90-day period).

     SECTION 2.16. Break Funding Payments. In the event of (a) the payment of any
principal of any Eurodollar Loan other than on the last day of an Interest Period applicable

38

 

thereto (including as a result of an Event of Default), (b) the conversion of any Eurodollar Loan
other than on the last day of the Interest Period applicable thereto, (c) the failure to borrow,
convert, continue or prepay any Revolving Loan or Term Loan on the date specified in any notice
delivered pursuant hereto (regardless of whether such notice may be revoked under Section 2.11(b)
and is revoked in accordance therewith), or (d) the assignment of any Eurodollar Loan other than on
the last day of the Interest Period applicable thereto as a result of a request by the Borrower
pursuant to Section 2.19, then, in any such event, the Borrower shall compensate each Lender for
the loss, cost and expense (excluding loss of anticipated profits) attributable to such event. A
certificate of any Lender setting forth, in reasonable detail showing the computation thereof, any
amount or amounts that such Lender is entitled to receive pursuant to this Section shall be
delivered to the Borrower and shall be conclusive absent manifest error. The Borrower shall pay
such Lender the amount shown as due on any such certificate within 10 days after receipt thereof,
if such certificate complies herewith.

     SECTION 2.17. Taxes. (a) Any and all payments by or on account of any obligation of
the Borrower hereunder shall be made free and clear of and without deduction for any Indemnified
Taxes or Other Taxes; provided that if the Borrower shall be required to deduct any
Indemnified Taxes or Other Taxes from such payments, then (i) the sum payable shall be increased as
necessary so that after making all required deductions (including deductions applicable to
additional sums payable under this Section) the Administrative Agent, any Lender or Issuing Bank
(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 Governmental Authority in accordance with applicable law.

     (b) In addition, the Borrower shall pay any Other Taxes to the relevant Governmental Authority
in accordance with applicable law.

     (c) The Borrower shall indemnify the Administrative Agent, each Lender and the Issuing Bank,
within 10 days after written demand therefor, for the full amount of any Indemnified Taxes or Other
Taxes paid by the Administrative Agent, such Lender or the Issuing
Bank, as the case may be, on or with respect to any payment by or on account of any obligation
of the Borrower hereunder (including Indemnified Taxes or Other Taxes imposed or asserted on or
attributable to amounts payable under this Section) and any penalties, interest and reasonable
expenses arising therefrom or with respect thereto, whether or not such Indemnified Taxes or Other
Taxes were correctly or legally imposed or asserted by the relevant Governmental Authority;
provided that the Borrower shall not be required to indemnify or reimburse a Lender
pursuant to this Section for any Indemnified Taxes or Other Taxes imposed or asserted more than 90
days prior to the date that such Lender notifies the Borrower of the Indemnified Taxes or Other
Taxes imposed or asserted and of such Lender’s intention to claim compensation therefor;
provided further that, if the Indemnified Taxes or Other Taxes imposed or asserted
giving rise to such claims are retroactive, then the 90-day period referred to above shall be
extended to include the period of retroactive effect thereof (to the extent that such period of
retroactive effect is not already included in such 90-day period). A certificate setting forth, in
reasonable detail showing the computation thereof, the amount of such payment or liability
delivered to the Borrower by a Lender or the Issuing Bank, or by the Administrative Agent on its
own behalf or on behalf of a Lender or the Issuing Bank, shall be conclusive absent manifest error.

39

 

     (d) As soon as practicable after any payment of Indemnified Taxes or Other Taxes by the
Borrower to a Governmental Authority, the Borrower shall deliver to the Administrative Agent the
original or a certified copy of a receipt issued by such Governmental Authority evidencing such
payment, a copy of the return reporting such payment or other evidence of such payment reasonably
satisfactory to the Administrative Agent.

     (e) Any Foreign Lender that is entitled to an exemption from or reduction of withholding tax
under the law of the jurisdiction in which the Borrower is located, or any treaty to which such
jurisdiction is a party, with respect to payments under this Agreement shall deliver to the
Borrower (with a copy to the Administrative Agent), at the time or times prescribed by applicable
law, such properly completed and executed documentation prescribed by applicable law or reasonably
requested by the Borrower as will permit such payments to be made without withholding or at such
reduced rate. If a payment made to a Lender under this Agreement would not be subject (in whole or
in part) to U.S. federal withholding tax imposed by FATCA if such Lender were to comply with the
applicable reporting or disclosure requirements of FATCA (including those contained in Section
1471(b) or 1472(b) of the Code, as applicable), such Lender shall deliver to the Borrower and
Administrative Agent, at the time or times prescribed by law and at such time or times reasonably
requested by the Borrower or Administrative Agent, such documentation or certifications prescribed
by applicable law (including as prescribed by Section 1471(b)(3)(C)(i) of the Code) and such
additional documentation or certifications reasonably requested by the Borrower or Administrative
Agent as may be necessary for the Borrower or Administrative Agent to comply with its obligations
to withhold or report under FATCA, to determine that such Lender has complied with such Lender’s
obligations under FATCA or to determine the amount (if any) to deduct and withhold from such
payment. Each Foreign Lender shall promptly notify the Borrower and the Administrative Agent at
any time it determines that it is no longer in a position to provide any previously delivered form,
certificate or other item to the Borrower (or any other form of certification adopted by the U.S.
taxing authorities for such purpose).

     (f) Should any Lender, the Administrative Agent or the Issuing Bank during the term of this
Agreement ever receive any refund, credit or deduction from any taxing authority to
which such Lender, the Administrative Agent or the Issuing Bank would not be entitled but for
the payment by the Borrower of Taxes (it being understood that the decision as to whether or not to
claim, and if claimed, as to the amount of any such refund, credit or deduction shall be made by
such Lender, the Administrative Agent or the Issuing Bank in its sole discretion), such Lender, the
Administrative Agent or the Issuing Bank, as the case may be, thereupon shall repay to the Borrower
an amount with respect to such refund, credit or deduction equal to any net reduction in taxes
actually obtained by such Lender, the Administrative Agent or the Issuing Bank, as the case may be,
and determined by such Lender, the Administrative Agent or the Issuing Bank, as the case may be, to
be attributable to such refund, credit or deduction.

     (g) Except for a request by the Borrower under Section 2.19(b), no Foreign Lender shall be
entitled to the benefits of Sections 2.17(a) or 2.17(c) if withholding tax is imposed on amounts
payable to such Foreign Lender at the time such Foreign Lender becomes a party to this Agreement or
designates a new lending office.

     SECTION 2.18. Payments Generally; Pro Rata Treatment; Sharing of Set-offs. (a) The
Borrower shall make each payment required to be made by it hereunder (whether of principal,
interest, fees or reimbursement of LC Disbursements, or of amounts payable under Section 2.15,

40

 

2.16 or 2.17, or otherwise) prior to 1:00 p.m., New York City time, on the date when due, in immediately
available funds, without set-off or counterclaim. Any amounts received after such time on any date
may, in the discretion of the Administrative Agent, be deemed to have been received on the next
succeeding Business Day for purposes of calculating interest thereon. All such payments shall be
made to the Administrative Agent at its offices at 301 South College Street, Charlotte, North
Carolina 28288-0608, except payments to be made directly to the Issuing Bank or Swingline Lender as
expressly provided herein and except that payments pursuant to Sections 2.15, 2.16, 2.17 and 9.03
shall be made directly to the Persons entitled thereto); provided, if any Lender shall
become a Defaulting Lender, from and after the date upon which such Lender shall have become a
Defaulting Lender, any payment made on account of principal of or interest on the Revolving Loans
shall be applied as set forth in Section 2.21(a)(ii), provided, further, that the
application of such payments in accordance herewith shall not constitute an Event of Default or a
Default, and no payment of principal of or interest on the Revolving Loans of such Defaulting
Lender shall be considered to be overdue, if, had such payments been applied without regard hereto,
no such Event of Default or Default would have occurred and no such payment of principal of or
interest on the Revolving Loans of such Defaulting Lender would have been overdue. The
Administrative Agent shall distribute any such payments received by it for the account of any other
Person to the appropriate recipient promptly following receipt thereof. If any payment hereunder
shall be due on a day that is not a Business Day, the date for payment shall be extended to the
next succeeding Business Day, and, in the case of any payment accruing interest, interest thereon
shall be payable for the period of such extension. All payments hereunder shall be made in
dollars.

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

     (c) If any Lender shall, by exercising any right of set-off or counterclaim or otherwise,
obtain payment (other than any payment to a dissenting Lender pursuant to Section 2.01(c)) in
respect of any principal of or interest on any of its Revolving Loans or participations in LC
Disbursements, Term Loans or Swingline Loans resulting in such Lender receiving payment of a
greater proportion of the aggregate amount of its Revolving Loans and participations in LC
Disbursements, Term Loans and Swingline Loans and accrued interest thereon than the proportion
received by any other Lender, then the Lender receiving such greater proportion shall purchase (for
cash at face value) participations in the Revolving Loans and participations in LC Disbursements,
Term Loans and Swingline Loans of other Lenders to the extent necessary so that the benefit of all
such payments shall be shared by the Lenders ratably in accordance with the aggregate amount of
principal of and accrued interest on their respective Revolving Loans and participations in LC
Disbursements, Term Loans and Swingline Loans; provided that (i) if any such
participations are purchased and all or any portion of the payment giving rise thereto is
recovered, such participations shall be rescinded and the purchase price restored to the extent of
such recovery, without interest, and (ii) the provisions of this paragraph shall not be construed
to apply to any payment made by the Borrower pursuant to and in

41

 

accordance with the express terms
of this Agreement or any payment obtained by a Lender as consideration for the assignment of or
sale of a participation in any of its Loans or participations in LC Disbursements to any assignee
or participant, other than to the Borrower or any Subsidiary or Affiliate thereof (as to which the
provisions of this paragraph shall apply). The Borrower consents to the foregoing and agrees, to
the extent it may effectively do so under applicable law, that any Lender acquiring a participation
pursuant to the foregoing arrangements may exercise against the Borrower rights of set-off and
counterclaim with respect to such participation as fully as if such Lender were a direct creditor
of the Borrower in the amount of such participation.

     (d) Unless the Administrative Agent shall have received notice from the Borrower prior to the
date on which any payment is due to the Administrative Agent for the account of the Lenders or the
Issuing Bank hereunder that the Borrower will not make such payment, the Administrative Agent may
assume that the Borrower has made such payment on such date in accordance herewith and may, in
reliance upon such assumption, distribute to the Lenders or the Issuing Bank, as the case may be,
the amount due. In such event, if the Borrower has not in fact made such payment, then each of the
Lenders or the Issuing Bank, as the case may be, severally agrees to repay to the Administrative
Agent forthwith on demand the amount so distributed to such Lender or Issuing Bank with interest
thereon, for each day from and including the date such amount is distributed to it to but excluding
the date of payment to the Administrative Agent, at the greater of the Federal Funds Effective Rate
and a rate determined by the Administrative Agent in accordance with banking industry rules on
interbank compensation.

     (e) If any Lender shall fail to make any payment required to be made by it pursuant to Section
2.05(c), 2.06(d) or (e), 2.07(b) or 2.18(d), then the Administrative Agent may, in its discretion
(notwithstanding any contrary provision hereof), apply any amounts thereafter received by the
Administrative Agent for the account of such Lender to satisfy such Lender’s obligations under such
Sections until all such unsatisfied obligations are fully paid.

     SECTION 2.19. Mitigation Obligations; Replacement of Lenders. (a) If any
Lender requests compensation under Section 2.15 or Section 2.13(f), or if the Borrower is
required to pay any additional amount to any Lender or any Governmental Authority for the account
of any Lender pursuant to Section 2.17, then such Lender shall use reasonable efforts to designate
a different lending office for funding or booking its Loans hereunder or to assign its rights and
obligations hereunder to another of its offices, branches or affiliates, if, in the judgment of
such Lender, such designation or assignment (i) would eliminate or reduce amounts payable pursuant
to Section 2.13(f), 2.15 or 2.17, as the case may be, in the future and (ii) would not subject such
Lender to any unreimbursed cost or expense and would not otherwise be disadvantageous to such
Lender. The Borrower hereby agrees to pay all reasonable costs and expenses incurred by any Lender
in connection with any such designation or assignment. Subject to the foregoing, Lenders agree to
use reasonable efforts to select lending offices which will minimize taxes and other costs and
expenses for the Borrower.

     (b) If any Lender requests compensation under Section 2.13(f) or Section 2.15, or if the
Borrower is required to pay any additional amount to any Lender or any Governmental Authority for
the account of any Lender pursuant to Section 2.17, or if any Lender refuses to consent to an
extension pursuant to Section 2.01(c), or if any Lender is a Defaulting Lender, then the Borrower
may, at its sole expense and effort, upon notice to such Lender and the Administrative Agent,
require such Lender to assign and delegate, without recourse (in accordance with and subject to the
restrictions contained in Section 9.04), all its interests, rights

42

 

and obligations under this
Agreement to an assignee that shall assume such obligations (which assignee may be another Lender,
if a Lender accepts such assignment); provided that (i) the Borrower shall have
received the prior written consent of the Administrative Agent (and, if a Revolving Credit
Commitment is being assigned, the Issuing Banks and Swingline Lender), which consent shall not
unreasonably be withheld, (ii) such Lender shall have received payment of an amount equal to the
outstanding principal of its Revolving Loans and participations in LC Disbursements, Term Loans and
Swingline Loans, accrued interest thereon, accrued fees and all other amounts payable to it
hereunder, from the assignee (to the extent of such outstanding principal and accrued interest and
fees) or the Borrower (in the case of all other amounts) and (iii) in the case of any such
assignment resulting from a claim for compensation under Section 2.13(f) or Section 2.15 or
payments required to be made pursuant to Section 2.17, such assignment will result in a reduction
in such compensation or payments. A Lender shall not be required to make any such assignment and
delegation if, prior thereto, as a result of a waiver by such Lender or otherwise, the
circumstances entitling the Borrower to require such assignment and delegation cease to apply. If
any Lender refuses to assign and delegate all its interests, rights and obligations under this
Agreement after the Borrower has required such Lender to do so as a result of a claim for
compensation under Section 2.13(f) or Section 2.15 or payments required to be made pursuant to
Section 2.17, such Lender shall not be entitled to receive such compensation or required payments.

     SECTION 2.20. Separateness. The Lenders acknowledge and affirm (i) their reliance on
the separateness of the Borrower and General Partner from each other and from other Persons,
including Enterprise Products OLLC, Enterprise Products Partners, EPCO and Enterprise GP Holdings,
(ii) that other creditors of the Borrower or the General Partner have likely advanced funds to such
Persons in reliance upon the separateness of the Borrower and General Partner from each other and
from other Persons, including Enterprise Products OLLC, Enterprise Products Partners, EPCO and
Enterprise GP Holdings, (iii) that each of the Borrower and General Partner have assets and
liabilities that are
separate from those of each other and from other Persons, including Enterprise Products OLLC,
Enterprise Products Partners, EPCO and Enterprise GP Holdings, (iv) that the Loans and other
obligations owing under this Agreement, the Notes and documents related hereto or thereto have not
been guaranteed by General Partner, Enterprise Products OLLC, Enterprise Products Partners, EPCO or
Enterprise GP Holdings, and (v) that, except as other Persons may expressly assume or guarantee
this Agreement, the Notes or any documents related hereto or thereto or any of the Loans or other
obligations thereunder, the Lenders shall look solely to the Borrower and its property and assets,
and any property pledged as collateral with respect hereto or thereto, for the repayment of any
amounts payable pursuant hereto or thereto and for satisfaction of any obligations owing to the
Lenders hereunder or thereunder.

     SECTION 2.21. Defaulting Lenders.

     (a) Adjustments. Notwithstanding anything to the contrary contained in this
Agreement, if any Lender becomes a Defaulting Lender, then, until such time as that Lender is no
longer a Defaulting Lender, to the extent permitted by applicable law:

     (i) Waivers and Amendments. That Defaulting Lender’s right to approve or
disapprove any amendment, waiver or consent with respect to this Agreement shall be
restricted as set forth in Section 9.02(b).

43

 

     (ii) Reallocation of Payments. Any payment of principal, interest, fees or
other amounts received by the Administrative Agent for the account of that Defaulting Lender
(whether voluntary or mandatory, at maturity, pursuant to Article VIII or otherwise,
and including any amounts made available to the Administrative Agent by that Defaulting
Lender pursuant to Section 9.08), shall be applied at such time or times as may be
determined by the Administrative Agent as follows: first, to the payment of any amounts
owing by that Defaulting Lender to the Administrative Agent hereunder; second, to the
payment on a pro rata basis of any amounts owing by that Defaulting Lender to the Issuing
Banks or Swingline Lender hereunder; third, to be held as cash collateral, if any cash
collateral is required to be delivered pursuant to Section 2.06(j) with respect to any
Fronting Exposure of such Defaulting Lender not fully reallocated pursuant to clause (iv)
below, for future funding obligations of that Defaulting Lender as to its participation in
any Swingline Loan or Letter of Credit; fourth, as the Borrower may request (so long as no
Default or Event of Default exists), to the funding of any Revolving Loan in respect of
which that Defaulting Lender has failed to fund its portion thereof as required by this
Agreement, as determined by the Administrative Agent; fifth, if so determined by the
Administrative Agent and the Borrower, to be held in a non-interest bearing deposit account
and released in order to satisfy obligations of that Defaulting Lender to fund Revolving
Loans under this Agreement; sixth, to the payment of any amounts then owing to the Lenders,
the Issuing Bank or Swingline Lender as a result of any judgment of a court of competent
jurisdiction obtained by any Lender, the Issuing Bank or Swingline Lender against that
Defaulting Lender as a result of that Defaulting Lender’s breach of its obligations under
this Agreement; seventh, so long as no Default or Event of Default exists, to the payment of
any amounts then owing to the Borrower as a result of any judgment of a court of competent
jurisdiction obtained by the Borrower against that Defaulting Lender as a result of that
Defaulting Lender’s breach of its obligations under this Agreement; and eighth, to that
Defaulting Lender or as otherwise directed by a court
of competent jurisdiction; provided that if (x) such payment is a payment of the
principal amount of any Revolving Loans or LC Disbursements in respect of which that
Defaulting Lender has not fully funded its appropriate share and (y) such Revolving Loans or
LC Disbursements were made at a time when the conditions set forth in Section 4.02 were
satisfied or waived, such payment shall be applied solely to pay the Revolving Loans of, and
LC Disbursements owed to, all non-Defaulting Lenders on a pro rata basis prior to being
applied to the payment of any Revolving Loans of, or LC Disbursements owed to, that
Defaulting Lender. Any payments, prepayments or other amounts paid or payable to a
Defaulting Lender that are applied (or held) to pay amounts owed by a Defaulting Lender or
to post cash collateral pursuant to this section shall be deemed paid to and redirected by
that Defaulting Lender, and each Lender irrevocably consents hereto. Upon making any
payment to the Administrative Agent or any Issuing Bank for the account of a Defaulting
Lender, the Borrower’s obligation to pay such amount to such Defaulting Lender shall be
fully discharged and such Defaulting Lender shall have no recourse to the Borrower for the
payment of such amount.

     (iii) Certain Fees. That Defaulting Lender shall not be entitled to receive
any facility fees with respect to its undrawn Revolving Credit Commitment pursuant to
Section 2.12(a) or fees with respect to its participation in Letters of Credit pursuant to
Section 2.12(b) for any period during which that Lender is a Defaulting Lender (and the

44

 

Borrower shall not be required to pay any such fee that otherwise would have been required
to have been paid to that Defaulting Lender).

     (iv) Reallocation of Applicable Revolving Credit Percentages to Reduce Fronting
Exposure. During any period in which there is a Defaulting Lender, for purposes of
computing the amount of the obligation of each non-Defaulting Lender to acquire, refinance
or fund participations in Letters of Credit or Swingline Loans pursuant to Section 2.05(c)
and 2.06(d), the “Applicable Revolving Credit Percentage” of each non-Defaulting Lender
shall be computed without giving effect to the Revolving Credit Commitment of that
Defaulting Lender; provided, that, (i) each such reallocation shall be given effect only if,
at the date the applicable Lender becomes a Defaulting Lender, no Default or Event of
Default exists; and (ii) the aggregate obligation of each non-Defaulting Lender to acquire,
refinance or fund participations in Letters of Credit and Swingline Loans shall not exceed
the positive difference, if any, of (1) the Revolving Credit Commitment of that
non-Defaulting Lender minus (2) the Revolving Credit Exposure of that non-Defaulting
Lender.

     (b) Defaulting Lender Cure. If the Borrower, the Administrative Agent, Swingline
Lender and the Issuing Banks agree in writing in their sole discretion that a Defaulting Lender
should no longer be deemed to be a Defaulting Lender, the Administrative Agent will so notify the
parties hereto, whereupon as of the effective date specified in such notice and subject to any
conditions set forth therein (which may include arrangements with respect to any cash collateral),
that Lender will, to the extent applicable, purchase that portion of outstanding Revolving Loans of
the other Lenders or take such other actions as the Administrative Agent may determine to be
necessary to cause the Revolving Loans and funded and unfunded participations in Letters of Credit
and Swingline Loans to be held on a pro rata basis by the Lenders in accordance with their
Applicable Revolving Credit Percentages (without giving effect to clause (a)(iv) above, whereupon
that Lender will cease to be a Defaulting Lender; provided that no adjustments will
be made retroactively with respect to fees accrued or payments made by or on behalf of the
Borrower while that Lender was a Defaulting Lender; and provided, further, that
except to the extent otherwise expressly agreed by the affected parties, no change hereunder from
Defaulting Lender to Lender will constitute a waiver or release of any claim of any party hereunder
arising from that Lender’s having been a Defaulting Lender.

ARTICLE III

Representations and Warranties

     The Borrower represents and warrants to the Lenders that:

     SECTION 3.01. Organization; Powers. Each of the Borrower and its Subsidiaries is
duly formed, validly existing and (if applicable) in good standing (except, with respect to
Subsidiaries other than Material Subsidiaries, where the failure to be in good standing,

Effect) under the laws of the jurisdiction of its organization, has all requisite power and
authority to carry on its business in all material respects as now conducted and, except where the
failure to do so, individually or in the aggregate, could not reasonably be expected to result in a
Material Adverse Effect, is qualified to do business in, and (if applicable) is in good standing

agreement or other instrument binding upon the Borrower or any of its Subsidiaries or its assets,
or give rise to a right thereunder to require any payment to be made by the Borrower or any of its

heretofore furnished to the Lenders the consolidated balance sheets of the Borrower and its
consolidated Subsidiaries and the related consolidated statements of income, equity and cash flow

accordance with GAAP, subject to year-end audit adjustments and the absence of footnotes in the
case of the statements referred to in clause (ii) above.

     (b) No Material Adverse Change exists; provided, on and after the date on which the
Borrower obtains an investment-grade rating on its Index Debt from any of Moody’s, S&P or Fitch,
Borrower makes no representation or warranty with respect to the foregoing.

     SECTION 3.05. Litigation and Environmental Matters. (a) There are no actions, suits
or proceedings by or before any arbitrator or Governmental Authority pending against or, to the
knowledge of the Borrower, threatened in writing against or affecting the Borrower or any of its
Subsidiaries (i) as to which there is a reasonable possibility of an adverse determination and
that, if adversely determined, could reasonably be expected, individually or in the aggregate, to
result in a Material Adverse Effect (other than the Disclosed Matters) or (ii) that involve this
Agreement or the Transactions.

     (b) Except for the Disclosed Matters and except with respect to any other matters that,
individually or in the aggregate, could not reasonably be expected to result in a Material Adverse

Environmental Law or to obtain, maintain or comply with any permit, license or other approval

46

 

required under any Environmental Law, (ii) has become subject to any Environmental Liability, (iii)
has received notice of any claim with respect to any Environmental Liability or (iv) knows of any
basis for any Environmental Liability.

     (c) Since the date of this Agreement, there has been no change in the status of the Disclosed

     SECTION 3.06. Compliance with Laws. Each of the Borrower and its Subsidiaries is in
compliance with all laws, regulations and orders of any Governmental Authority applicable to it or

reasonably be expected to result in a Material Adverse Effect. No Default has occurred and is
continuing.

to be paid all Taxes required to have been paid by it, except (a) Taxes that are being contested in
good faith by appropriate proceedings and for which the Borrower or such Subsidiary, as applicable,

     SECTION 3.09. ERISA. No ERISA Event has occurred or is reasonably expected to occur
that, when taken together with all other such ERISA Events for which liability is reasonably
expected to occur, could reasonably be expected to result in a Material Adverse Effect.

reports, financial statements, certificates or other information furnished by or on behalf of the
Borrower to the Administrative Agent or any Lender in connection with the negotiation of this
Agreement (as modified or supplemented by other information so furnished) contains any material
misstatement of fact or omits to state any material fact necessary to make the statements therein,
in the light of the circumstances under which they were made, not misleading; provided
that, with respect to projected financial information, the Borrower represents only that
such information was prepared in good faith based upon assumptions believed to be reasonable at the
time.

     SECTION 3.11. Subsidiaries. As of the Effective Date the Borrower has no

used to purchase or carry any margin stock in violation of said Regulations U or X or to extend
credit to others for the purpose of purchasing or carrying margin stock in violation of said
Regulations U or X.

     (b) Indebtedness of Project Finance Subsidiaries;

case of any Subsidiary that is not wholly-owned (directly or indirectly) by the Borrower, dividends
or payments, as the case may be, to the other owners of Equity Interests in such Subsidiary;
provided, any dividends or payments by any such Subsidiary that is not wholly-owned
(directly or indirectly) by the Borrower to the Borrower shall be not less than an amount equal to

Lenders pursuant hereto, which prohibits, restricts or imposes any conditions upon the ability of
any Subsidiary (other than Project Finance Subsidiaries) to (a) pay dividends or make other
distributions or pay any Indebtedness owed to the Borrower or any Subsidiary, or (b) make
subordinate loans or advances to or make other investments in the Borrower or any Subsidiary in
each case, other than restrictions or conditions contained in, or existing by reasons of, any
agreement or instrument (i) relating to any Indebtedness of any Subsidiary permitted by Section
6.01, (ii) relating to property existing at the time of the acquisition thereof, so long as the
restriction or condition relates only to the property so acquired, (iii) relating to any
Indebtedness of, or otherwise to, any Subsidiary at the time such Subsidiary was merged or
consolidated with or into, or acquired by, the Borrower or a Subsidiary or became a Subsidiary and
not created in contemplation thereof, (iv) effecting a renewal, extension, refinancing, refund or
replacement (or successive extensions, renewals, refinancings, refunds or replacements) of
Indebtedness issued under an agreement referred to in clauses (i) through (iii) above, so long as
the restrictions and conditions contained in any such renewal, extension, refinancing, refund or
replacement agreement, taken as a whole, are not materially more restrictive than the restrictions
and conditions contained in the original agreement, as determined in good faith by the board of
directors of the General Partner, (v) constituting customary provisions restricting subletting or
assignment of any leases of the Borrower or any Subsidiary or provisions in agreements that
restrict the assignment of such agreement or any rights thereunder, (vi) constituting restrictions
on the sale or other disposition of any property securing Indebtedness as a result of a Lien on

other deposits or assets imposed by customers and other persons under contracts entered into in the
ordinary course of business, (ix) constituting provisions contained in agreements or instruments
relating to Indebtedness that prohibit the transfer of all or substantially all of the assets of
the obligor under that agreement or instrument unless the transferee assumes the obligations of the
obligor under such agreement or instrument or such assets may be transferred subject to such
prohibition, (x) constituting a requirement that a certain amount of Indebtedness be maintained
between a Subsidiary and the Borrower or another Subsidiary, (xi) constituting any restriction or
condition with respect to property under an agreement that has been entered into for the
disposition of such property, provided that such disposition is otherwise permitted
hereunder, (xii) constituting any restriction or condition with respect to property under a
charter, lease or other agreement that has been entered into for the employment of such property or
(xiii) that is a Hybrid Security or an indenture, document, agreement or security entered into or
issued in connection with a Hybrid Security or otherwise constituting a restriction or condition on
the payment of dividends or distributions by an issuer of a Hybrid Security.

     SECTION 6.07 Financial Condition Covenants.

     (a) Ratio of Consolidated EBITDA to Consolidated Interest Expense. Until the Borrower
obtains an investment-grade rating on its Index Debt from any of Moody’s, S&P or Fitch, the
Borrower shall not permit its ratio of Consolidated EBITDA to Consolidated Interest Expense in each
case for the four full fiscal quarters most recently ended to be less than 2.75 to 1.00 as of the
last day of any fiscal quarter.

55

 

     (b) Leverage Ratio. The Borrower shall not permit its ratio of Consolidated
Indebtedness to Consolidated EBITDA in each case for the four full fiscal quarters most recently
ended (the “Leverage Ratio”) to exceed 5.00 to 1.00 as of the last day of any fiscal
quarter; provided, following a Specified Acquisition (defined below), such ratio shall not
exceed

5.50 to 1.00 as of the last day of (i) the fiscal quarter in which the Specified Acquisition
occurred (the “Acquisition Quarter”), and (ii) the two fiscal quarters following the
Acquisition Quarter, and

     5.00 to 1.00 as of the last day of any fiscal quarter thereafter.

As used herein, “Specified Acquisition” means, at the election of Borrower, one or more
acquisitions of assets or entities or operating lines or divisions in any rolling 12-month period
for an aggregate purchase price of not less than $25,000,000; provided, in the event the
Leverage Ratio exceeds 4.75 to 1.00 at the end of any fiscal quarter in which one or more
acquisitions otherwise qualifying as a Specified Acquisition but for Borrower’s failure to so elect
shall have occurred, Borrower shall be deemed to have so elected a Specified Acquisition with
respect thereto; provided, further, following the election (or deemed election) of
a Specified Acquisition, Borrower may not elect (or be deemed to have elected) a subsequent
Specified Acquisition unless, at the time of such subsequent election, the Leverage Ratio does not
exceed 4.75 to 1.00.

     (c) Calculation Methodology. For purposes of calculating the financial covenant
ratios set forth in this Section 6.07, the Project Finance Subsidiaries shall be disregarded. For
purposes of this Section 6.07(b), if during any period of four fiscal quarters the Borrower or any
Subsidiary acquires any Person (or any interest in any Person) or all or substantially all of the
assets of any Person, the EBITDA attributable to such assets or an amount equal to the percentage
of ownership of the Borrower or a Subsidiary, as the case may be, in such Person times the EBITDA
of such Person, for such period determined on a pro forma basis (which determination, in each case,
shall be subject to approval of the Administrative Agent, not to be unreasonably withheld) may be
included as Consolidated EBITDA for such period as if such acquisition occurred on the first day of
such four fiscal quarter period; provided that during the portion of such period
that follows such acquisition, the computation in respect of the EBITDA of such Person or such
assets, as the case may be, shall be made on the basis of actual (rather than pro forma) results.

In addition, for purposes of this Section 6.07: (i) Hybrid Securities up to an aggregate amount of
15% of Consolidated Total Capitalization shall be excluded from Consolidated Indebtedness, and (ii)
Consolidated EBITDA may include, at Borrower’s option, any Material Project EBITDA Adjustments as
provided in the definition thereof.

     SECTION 6.08 Asset Dispositions. The Borrower will not, and will not permit any of
its Subsidiaries (other than Project Finance Subsidiaries) to Dispose of any assets or properties,
other than (a) Dispositions of inventory in the ordinary course of business, (b) Dispositions for
which the consideration received therefor is less than $50,000 and Dispositions of machinery and
equipment no longer used or useful in the conduct of business of the Borrower and its Subsidiaries

transfer or otherwise dispose of any assets, tangible or intangible, to, or participate in, or
effect, any transaction with, any officer, director, employee or Affiliate (other than the Borrower
or any Subsidiary) unless any and all such transactions between the Borrower and its Subsidiaries
on the one hand and any officer, director, employee or Affiliate (other than the Borrower or any
Subsidiary) on the other hand, shall be on an arms-length basis and on terms no less favorable to
the Borrower or such Subsidiary than could have been obtained from a third party who was not an
officer, director, employee or Affiliate (other than the Borrower or any Subsidiary);
provided, that the foregoing provisions of this Section shall not (a) prohibit the Borrower
or any Subsidiary from declaring or paying any lawful dividend or distribution otherwise permitted
hereunder, (b) prohibit the Borrower or any Subsidiary from providing credit support for its
Subsidiaries (other than Project Finance Subsidiaries) as it deems appropriate in the ordinary
course of business, (c) prohibit the Borrower or any Subsidiary from engaging in a transaction or
transactions that are not on an arms-length basis or are not on terms as favorable as could have
been obtained from a third party, provided that such transaction or transactions occurs within a
related series of transactions, which, in the aggregate, are on an arms-length basis and are on
terms as favorable as could have been obtained from a third party, (d) prohibit the Borrower or any
Subsidiary from engaging in non-material transactions with any officer, director, employee or
Affiliate of the Borrower or any Subsidiary that are not on an arms-length basis or are not on
terms as favorable as could have been obtained from a third party but are in the ordinary course of
the Borrower’s or such Subsidiary’s business, so long as, in each case, after giving effect
thereto, no Default or Event of Default shall have occurred and be continuing, (e) prohibit any
agreements listed on Schedule 6.09 attached hereto, provided, any right of first refusal
with respect to the purchase of any assets of the Borrower or any Subsidiary (other than a Project
Finance Subsidiary) granted to any Affiliate shall by its terms automatically terminate upon the
occurrence of an Event of Default as described in Section 7(g), (h) or (i), or (f) prohibit the
Borrower or any Subsidiary from engaging in a transaction with an Affiliate if such transaction has
been approved by a majority of the General Partner’s independent directors.

ARTICLE VII

Events of Default

     If any of the following events (“Events of Default”) shall occur:

     (a) the Borrower shall fail to pay any principal of any Loan or any reimbursement obligation
in respect of any LC Disbursement when and as the same shall become due and payable, whether at the
due date thereof or at a date fixed for prepayment thereof or otherwise;

     (b) the Borrower shall fail to pay any interest on any Loan or any fee or any other amount
(other than an amount referred to in clause (a) of this Article) payable under this Agreement, when
and as the same shall become due and payable, and such failure shall continue unremedied for a
period of five (5) Business Days;

     (c) any representation or warranty made or deemed made by or on behalf of the Borrower or any
Subsidiary of the Borrower in or in connection with this Agreement or any amendment or modification
hereof or waiver hereunder, or in any report, certificate, financial statement or other document
furnished pursuant to or in connection with this Agreement or any amendment or modification hereof
or waiver hereunder, shall prove to have been incorrect in any material respect when made or deemed
made and such materiality is continuing;

     (d) the Borrower shall fail to observe or perform any covenant, condition or agreement
contained in Section 5.02, 5.03 (with respect to the Borrower’s existence) or 5.07 or in Article

contained in this Agreement (other than those specified in clause (a), (b) or (d) of this Article),

     (f) the Borrower or any Material Subsidiary (other than Project Finance Subsidiaries) shall
(i) fail to pay (A) any principal of or premium or interest on any Material Indebtedness of the

one or more Hedging Agreements (excluding amounts the validity of which are being contested in good
faith by appropriate proceedings, if necessary, and for which adequate reserves with respect
thereto are maintained on the books of the Borrower or such Material Subsidiary (as the case may
be)) in excess of $25,000,000, in each case when the same becomes due and payable (whether by
scheduled maturity, required prepayment, acceleration, demand or otherwise), and such failure shall
continue after the applicable grace period, if any, specified in the agreement or instrument
relating to such Material Indebtedness or such Hedging Agreements; or (ii) default in the
observance or performance of any covenant or obligation contained in any agreement or instrument

loan documents (in each case, other than a failure to pay specified in clause (i) of this
subsection (f)) and such default shall continue after the applicable grace period, if any,
specified in such agreement or instrument, if the effect thereof is to accelerate the maturity of
such Material Indebtedness or require such Material Indebtedness to be prepaid prior to the stated
maturity thereof; for the avoidance of doubt the parties acknowledge

58

 

and agree that any payment required to be made under a guaranty of payment or collection described in clause (c) of the
definition of Indebtedness shall be due and payable at the time such payment is due and payable
under the terms of such guaranty (taking into account any applicable grace period) and such payment

or greater than $25,000,000 shall be rendered against the Borrower or any Material Subsidiary
(other than Project Finance Subsidiaries) or any combination thereof and the same shall remain
undischarged for a period of 30 consecutive days during which execution shall not be effectively
stayed, or any action shall be legally taken by a judgment creditor to attach or levy upon any
assets of the Borrower or any such Material Subsidiary to enforce any such judgment;

     (k) an ERISA Event shall have occurred that, when taken together with all other ERISA Events
that have occurred, could reasonably be expected to result in liability of the Borrower and its

     (l) the General Partner takes, suffers or permits to exist any of the events or conditions
referred to in clauses (g), (h) or (i) of this Article; or

     (m) a Change in Control shall occur;

59

 

then, and in every such event (other than an event with respect to the Borrower described in clause
(g) or (h) of this Article), and at any time thereafter during the continuance of such event, the
Administrative Agent at the request of the Required Lenders (or, as to clause (i) below, Required
Revolving Lenders) shall, by notice to the Borrower, take either or both of the following actions,
at the same or different times: (i) terminate the Revolving Credit Commitments, and thereupon the
Revolving Credit Commitments shall terminate immediately, and (ii) declare the Loans then
outstanding to be due and payable in whole (or in part, in which case any principal not so declared
to be due and payable may thereafter be declared to be due and payable), and thereupon the
principal of the Loans so declared to be due and payable, together with accrued interest thereon
and all fees and other obligations of the Borrower accrued hereunder, shall become due and payable
immediately, without presentment, demand, protest or other notice of any kind, all of which are
hereby waived by the Borrower; and in case of any event with respect to the Borrower described in
clause (g) or (h) of this Article, the Revolving Credit Commitments shall automatically terminate
and the principal of the Loans then outstanding, together with accrued interest thereon and all
fees and other obligations of the Borrower accrued hereunder, shall automatically become due and payable, without presentment,
demand, protest or other notice of any kind, all of which are hereby waived by the Borrower.

ARTICLE VIII

The Administrative Agent

     Each of the Lenders and the Issuing Bank hereby irrevocably appoints the Administrative Agent
as its agent and authorizes the Administrative Agent to take such actions on its behalf and to
exercise such powers as are delegated to the Administrative Agent by the terms hereof, together
with such actions and powers as are reasonably incidental thereto.

     The bank serving as the Administrative Agent hereunder shall have the same rights and powers
in its capacity as a Lender as any other Lender and may exercise the same as though it were not the
Administrative Agent, and such bank and its Affiliates may accept deposits from, lend money to and
generally engage in any kind of business with the Borrower or any Subsidiary or other Affiliate
thereof as if it were not the Administrative Agent hereunder.

     The Administrative Agent shall not have any duties or obligations except those expressly set
forth herein. Without limiting the generality of the foregoing, (a) the Administrative Agent shall
not be subject to any fiduciary or other implied duties, regardless of whether a Default has
occurred and is continuing, (b) the Administrative Agent shall not have any duty to take any
discretionary action or exercise any discretionary powers, except discretionary rights and powers
expressly contemplated hereby that the Administrative Agent is required to exercise in writing by
the Required Lenders or Required Revolving Lenders (or such other number or percentage of the
Lenders as shall be necessary under the circumstances as provided in Section 9.02), and (c) except
as expressly set forth herein, the Administrative Agent shall not have any duty to disclose, and
shall not be liable for the failure to disclose, any information relating to the Borrower or any of
its Subsidiaries that is communicated to or obtained by the bank serving as Administrative Agent or
any of its Affiliates in any capacity. The Administrative Agent shall not be liable to the Lenders
for any action taken or not taken by it with the consent or at the request of the Required Lenders
or Required Revolving Lenders (or such other number or percentage of the Lenders as shall be
necessary under the circumstances as provided in Section 9.02) or in the absence of its own gross negligence or willful misconduct. The Administrative Agent shall be deemed not to

60

 

have knowledge of any Default unless and until written notice thereof is given to the Administrative Agent by the
Borrower or a Lender, and the Administrative Agent shall not be responsible for or have any duty to
ascertain or inquire into (i) any statement, warranty or representation made in or in connection
with this Agreement, (ii) the contents of any certificate, report or other document delivered
hereunder or in connection herewith, (iii) the performance or observance of any of the covenants,
agreements or other terms or conditions set forth herein, (iv) the validity, enforceability,
effectiveness or genuineness of this Agreement or any other agreement, instrument or document, or
(v) the satisfaction of any condition set forth in Article IV or elsewhere herein, other than to confirm receipt of items expressly required to be delivered
to the Administrative Agent.

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

     The Administrative Agent may perform any and all its duties and exercise its rights and powers
by or through any one or more sub-agents appointed by the Administrative Agent. The Administrative
Agent and any such sub-agent may perform any and all its duties and exercise its rights and powers
through their respective Related Parties. The exculpatory provisions of the preceding paragraphs
shall apply to any such sub-agent and to the Related Parties of the Administrative Agent and any
such sub-agent, and shall apply to their respective activities in connection with the syndication
of the credit facilities provided for herein as well as activities as Administrative Agent.
Anything herein to the contrary notwithstanding, neither the Administrative Agent, the
Co-Syndication Agents, the Co-Documentation Agents, the Joint Lead Arrangers nor the Joint Book
Runners listed on the cover page hereof shall have any powers, duties or responsibilities under
this Agreement, the Notes or any documents related hereto or thereto, except in its capacity, as
applicable, as Administrative Agent, Issuing Bank, Swingline Lender or a Lender hereunder.

     Subject to the appointment and acceptance of a successor Administrative Agent as provided in
this paragraph, the Administrative Agent may resign at any time by notifying the Lenders, the
Issuing Bank and the Borrower. Upon any such resignation, the Required Lenders shall have the
right, with the Borrower’s approval (which will not be unreasonably withheld), to appoint a
successor. If no successor shall have been so appointed by the Required Lenders and shall have
accepted such appointment within 30 days after the retiring Administrative Agent gives notice of
its resignation, then the retiring Administrative Agent may, with the Borrower’s approval (which
will not be unreasonably withheld or delayed, and the Borrower’s approval shall not be required if
an Event of Default has occurred which is continuing), on behalf of the Lenders and the Issuing
Bank, appoint a successor Administrative Agent which shall be a bank with an office in New York,
New York, or an Affiliate of any such bank and such bank, or its Affiliate, as applicable, shall
have capital and surplus equal to or greater than $500,000,000. Upon the acceptance of its
appointment as Administrative Agent hereunder by a successor, such

61

 

successor shall succeed to and become vested with all the rights, powers, privileges and duties of the retiring Administrative
Agent, and the retiring Administrative Agent shall be discharged from its duties and obligations
hereunder. The fees payable by the Borrower to a successor Administrative Agent shall be the same
as those payable to its predecessor unless otherwise agreed between the Borrower and such
successor. After the Administrative Agent’s resignation hereunder, the provisions of this Article
and Section 9.03 shall continue in effect for the benefit of such retiring Administrative Agent,
its sub-agents and their respective Related Parties in respect of any actions taken or omitted to be taken by any of them while it was acting as
Administrative Agent.

     Each Lender acknowledges that it has, independently and without reliance upon the
Administrative Agent or any other Lender and based on such documents and information as it has
deemed appropriate, made its own credit analysis and decision to enter into this Agreement. Each
Lender also acknowledges that it will, independently and without reliance upon the Administrative
Agent or any other Lender and based on such documents and information as it shall from time to time
deem appropriate, continue to make its own decisions in taking or not taking action under or based
upon this Agreement, any related agreement or any document furnished hereunder or thereunder.

     (f) The Borrower will have the option to provide to the Administrative Agent all information,
documents and other materials that it is obligated to furnish to the Administrative Agent pursuant
to this Agreement or any other document executed in connection herewith, including, without
limitation, all notices, requests, financial statements, financial and other reports, certificates
and other information materials, but excluding any such communication that (i) relates to a request
for a new, or a conversion of an existing, Borrowing or other extension of credit (including any
election of an interest rate or Interest Period relating thereto) or relates to the issuance,
amendment, renewal or extension of any Letter of Credit, (ii) relates to the payment of any
principal or other amount due under this Agreement prior to the scheduled date therefor, (iii)
provides notice of any Default or Event of Default, or (iv) other than the requirements set forth

precedent to the effectiveness of this Agreement and/or any Borrowing, any issuance, amendment,
renewal or extension of any Letter of Credit or any other extension of credit hereunder (all such
non-excluded communications being referred to herein collectively as “Communications”), by
transmitting the Communications in an electronic/soft medium in a format acceptable to the
Administrative Agent. The Borrower further agrees that the Administrative Agent may make the
Communications available to the Lenders and the Issuing Bank by posting the Communications on
SyndTrak or a substantially similar electronic transmission system (the “Platform”). The
Borrower acknowledges that the distribution of material through an electronic medium is not
necessarily secure and that there are confidentiality and other risks associated with such
distribution. The Platform is provided “as is” and “as available”. The Agent Parties (as
defined below) do not warrant the accuracy or completeness of the Communications, or the adequacy
of the Platform and expressly disclaim liability for errors or omissions in the Communications. No
warranty of any kind, express, implied or statutory, including, without limitation, any warranty of

63

 

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 Parties in connection with the
Communications or the Platform. In no event shall the Administrative Agent or 
any of its affiliates or any of their respective officers, directors, employees, agents,
advisors or representatives (collectively, “Agent Parties”) have any liability to the Borrower, any
Lender or any other Person or entity for damages of any kind, including, without limitation, direct
or indirect, special, incidental or consequential damages, losses or expenses (whether in tort,
contract or otherwise) arising out of the Borrower’s or the Administrative Agent’s transmission of
Communications through the internet, except to the extent the liability of any Agent Party is found
in a final non-appealable judgment by a court of competent jurisdiction to have resulted primarily
from such Agent Party’s gross negligence or willful misconduct. The Administrative Agent
agrees that the receipt of the Communications by the Administrative Agent at its e-mail address as
specified by the Administrative Agent from time to time shall constitute effective delivery of the
Communications to the Administrative Agent for purposes of this Agreement and any other documents
executed in connection herewith. Each of the Issuing Bank and the Lenders agrees that notice to it
(as provided in the next sentence) specifying that the Communications have been posted to the
Platform shall constitute effective delivery of the Communications to such Issuing Bank or Lender,
as the case may be, for purposes of this Agreement and any other documents executed in connection
herewith. Each of the Issuing Bank and the Lenders agrees to notify the Administrative Agent in
writing (including by electronic communication) from time to time of such Issuing Bank’s or
Lender’s, as the case may be, e-mail address to which the foregoing notice may be sent by
electronic transmission, and (ii) that the foregoing notice may be sent to such e-mail address.
Nothing herein shall prejudice the right of the Administrative Agent or any Lender to give any
notice or other communication pursuant hereto or any other document executed in connection herewith
in any other manner specified herein or therein.

Any party hereto may change its address or telecopy number for notices and other communications
hereunder by notice to the other parties hereto. All notices and other communications given to any
party hereto in accordance with the provisions of this Agreement shall be deemed to have been given
on the date of receipt.

     SECTION 9.02. Waivers; Amendments. (a) No failure or delay by the Administrative
Agent, the Issuing Bank or any Lender in exercising any right or power hereunder shall operate as a
waiver thereof, nor shall any single or partial exercise of any such right or power, or any
abandonment or discontinuance of steps to enforce such a right or power, preclude any other or
further exercise thereof or the exercise of any other right or power. The rights and remedies of
the Administrative Agent, the Issuing Bank and the Lenders hereunder are cumulative and are not
exclusive of any rights or remedies that they would otherwise have. No waiver of any provision of
this Agreement or consent to any departure by the Borrower therefrom shall in any event be
effective unless the same shall be permitted by paragraph (b) of this Section, and then such waiver
or consent shall be effective only in the specific instance and for the purpose for which given.
Without limiting the generality of the foregoing, the making of a Loan or issuance of a Letter of
Credit shall not be construed as a waiver of any Default, regardless of whether the Administrative
Agent, any Lender or the Issuing Bank may have had notice or knowledge of such Default at the time.

64

 

     (b) Neither this Agreement nor any provision hereof may be waived, amended or modified except
pursuant to an agreement or agreements in writing entered into by the Borrower and the Required
Lenders (or the Required Revolving Lenders, as applicable) or by the Borrower and the
Administrative Agent with the consent of the Required Lenders (or the Required Revolving Lenders, as applicable); provided that no such agreement shall (i)
increase or extend the Revolving Credit Commitment of any Lender without the written consent of
such Lender, (ii) reduce the principal amount of any Loan or LC Disbursement or reduce the rate of
interest thereon, or reduce any fees payable hereunder, without the written consent of each Lender
affected thereby, (iii) postpone the scheduled date of payment of the principal amount of any Loan
or LC Disbursement, or any interest thereon, or any fees payable hereunder, or reduce the amount
of, waive or excuse any such payment, or postpone the scheduled date of expiration of any Revolving
Credit Commitment, without the written consent of each Lender affected thereby, (iv) change Section
2.18(b) or (c) in a manner that would alter the pro rata sharing of payments required thereby,
without the written consent of each Lender, or (v) change any of the provisions of this Section or
the definition of “Required Lenders” or any other provision hereof specifying the number or
percentage of Lenders required to waive, amend or modify any rights hereunder or make any
determination or grant any consent hereunder, without the written consent of each Lender (or, as to
any change to the definition of “Required Revolving Lenders”, the written consent of each Revolving
Lender); provided further that no such agreement shall amend, modify or otherwise affect
the rights or duties of the Administrative Agent, the Issuing Bank or the Swingline Lender
hereunder without the prior written consent of the Administrative Agent, the Issuing Bank or the
Swingline Lender, as the case may be. Notwithstanding anything to the contrary herein, the
Revolving Commitment and outstanding Loans of a Defaulting Lender shall be disregarded for all
purposes of any determination of whether the requisite Lenders have taken or may take any action
hereunder, and any amendment, waiver or consent which by its terms requires the consent of all
Lenders or each affected Lender may be effected with the consent of the applicable Lenders other
than Defaulting Lenders, except that (x) the Revolving Credit Commitment of any Defaulting Lender
may not be increased or extended, nor may the Term Loan Maturity Date be extended, nor may the
outstanding principal of any Loan owed to such Defaulting Lender be forgiven without the consent of
such Defaulting Lender and (y) any waiver, amendment or modification requiring the consent of all
Lenders or each affected Lender that by its terms affects any Defaulting Lender more adversely than
other affected Lenders shall require the consent of such Defaulting Lender.

     SECTION 9.03. Expenses; Indemnity; Damage Waiver. (a) The Borrower shall pay (i)
all reasonable out-of-pocket expenses incurred by the Administrative Agent and its Affiliates,
including the reasonable fees, charges and disbursements of one law firm as counsel for the
Administrative Agent, in connection with the syndication (prior to the Effective Date) of the
credit facilities provided for herein, the preparation and administration of this Agreement or any
amendments, modifications or waivers of the provisions hereof (whether or not the transactions
contemplated hereby or thereby shall be consummated), (ii) all reasonable out-of-pocket expenses
incurred by the Issuing Bank in connection with the issuance, amendment, renewal or extension of
any Letter of Credit or any demand for payment thereunder and (iii) all out-of-pocket expenses
reasonably incurred during the existence of an Event of Default by the Administrative Agent, the
Issuing Bank or any Lender, including the fees, charges and disbursements of any counsel for the
Administrative Agent, the Issuing Bank or any Lender, in connection with the enforcement or
protection of its rights in connection with this Agreement, including its rights under this
Section, or in connection with the Loans made or Letters of Credit

65

 

issued hereunder, including all such out-of-pocket expenses incurred during any workout, restructuring or negotiations in respect
of such Loans or Letters of Credit.

     (b) The Borrower shall indemnify the Administrative Agent, the Issuing Bank and each Lender,
and each Related Party of any of the foregoing Persons (each such Person being called an
“Indemnitee”) against, and hold each Indemnitee harmless from, any and all losses, claims,
damages, liabilities and related expenses, including the fees, charges and disbursements of any
counsel for any Indemnitee, incurred by or asserted against any Indemnitee arising out of, in
connection with, or as a result of (i) the execution or delivery of this Agreement or any agreement
or instrument contemplated hereby, the performance by the parties hereto of their respective
obligations hereunder or the consummation of the Transactions or any other transactions
contemplated hereby, (ii) any Loan or Letter of Credit or the use of the proceeds therefrom
(including any refusal by the Issuing Bank to honor a demand for payment under a Letter of Credit
if the documents presented in connection with such demand do not strictly comply with the terms of
such Letter of Credit), (iii) any actual or alleged presence or release of Hazardous Materials on
or from any property owned or operated by the Borrower or any of its Subsidiaries, or any
Environmental Liability related in any way to the Borrower or any of its Subsidiaries, or (iv) any
actual or prospective claim, litigation, investigation or proceeding relating to any of the
foregoing, whether based on contract, tort or any other theory and regardless of whether any
Indemnitee is a party thereto; provided that such indemnity shall not, as to any
Indemnitee, be available (x) to the extent that such losses, claims, damages, liabilities or
related expenses resulted from the gross negligence or willful misconduct of such Indemnitee or any
Related Party of such Indemnitee, or (y) in connection with disputes among or between the
Administrative Agent, Lenders, Issuing Bank and/or their respective Related Parties.

     (c) To the extent that the Borrower fails to pay any amount required to be paid by it to the
Administrative Agent, the Issuing Bank or the Swingline Lender under paragraph (a) or (b) of this
Section, each Lender severally agrees to pay to the Administrative Agent, the Issuing Bank or the
Swingline Lender, as the case may be, such Lender’s Applicable Revolving Credit Percentage and
Applicable Term Loan Percentage (determined as of the time that the applicable unreimbursed expense
or indemnity payment is sought) of such unpaid amount; provided that the
unreimbursed expense or indemnified loss, claim, damage, liability or related expense, as the case
may be, was incurred by or asserted against the Administrative Agent, the Issuing Bank or the
Swingline Lender in its capacity as such.

     (d) To the extent permitted by applicable law, the Borrower shall not assert, and hereby
waives, any claim against any Indemnitee, on any theory of liability, for indirect, special,
consequential or punitive damages (as opposed to direct or actual damages) arising out of, in
connection with, or as a result of, this Agreement or any agreement or instrument contemplated
hereby, the Transactions, any Loan or Letter of Credit or the use of the proceeds thereof.

     (e) All amounts due under this Section shall be payable not later than 30 days after written
demand therefor, such demand to be in reasonable detail setting forth the basis for and method of
calculation of such amounts.

     SECTION 9.04. Successors and Assigns. (a) The provisions of this Agreement shall be
binding upon and inure to the benefit of the parties hereto and their respective successors and
assigns permitted hereby (including any Affiliate of the Issuing Bank that issues any Letter of
Credit), except that the Borrower may not assign or otherwise transfer any of its rights or

66

 

obligations hereunder without the prior written consent of each Lender (and any attempted
assignment or transfer by the Borrower without such consent shall be null and void). 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 (including any Affiliate of the Issuing Bank
that issues any Letter of Credit) and, to the extent expressly contemplated hereby, the Related
Parties of each of the Administrative Agent, the Issuing Bank and the Lenders) any legal or
equitable right, remedy or claim under or by reason of this Agreement.

     (b) Any Lender may assign to one or more assignees (other than the Borrower or an Affiliate of
the Borrower or a Defaulting Lender) all or a portion of its rights and obligations under this
Agreement (including all or a portion of its Revolving Credit Commitment and Revolving Loans owing
to it and/or Term Loans at the time owing to it); provided that (i) except in the case of
an assignment to a Lender (or an Affiliate of a Lender with a rating of at least A from S&P or A2
from Moody’s), each of the Borrower and the Administrative Agent (and, in the case of an assignment
of all or a portion of a Revolving Credit Commitment or any Lender’s obligations in respect of its
LC Exposure or Swingline Exposure, each Issuing Bank and the Swingline Lender) must give their
prior written consent to such assignment (which consent shall not be unreasonably withheld or
delayed), (ii) except in the case of an assignment to a Lender or an Affiliate of a Lender or an
assignment of the entire remaining amount of the assigning Lender’s Revolving Credit Commitment and
Revolving Loans and/or Term Loan, as applicable, the amount of the Revolving Credit Commitment and
Revolving Loans and/or Term Loan, as applicable, of the assigning Lender subject to each such
assignment (determined as of the date the Assignment and Acceptance with respect to such assignment
is delivered to the Administrative Agent) shall not be less than $5,000,000 unless each of the
Borrower and the Administrative Agent otherwise consent, (iii) each partial assignment of a
Revolving Credit Commitment and Revolving Loans and/or Term Loan, as the case may be, shall result
in the assignor retaining a Revolving Credit Commitment and Revolving Loans and/or Term Loan, as
applicable, of not less than $10,000,000 and shall be made as an assignment of a proportionate part
of all the assigning Lender’s rights and obligations under this Agreement with respect to such
Revolving Credit Commitment and Revolving Loans and/or Term Loan, (iv) the parties (other than the
Borrower) to each assignment shall execute and deliver to the Administrative Agent an Assignment
and Acceptance, together with a processing and recordation fee of $3,500, (v) the assignee, if it
shall not be a Lender, shall deliver to the Administrative Agent an Administrative Questionnaire
and (vi) no assignment to a foreign bank shall be made hereunder unless, at the time of such
assignment, there is no withholding tax applicable with respect to such foreign bank for which the
Borrower would be or become responsible under Section 2.17; and provided further that any
consent of the Borrower otherwise required under this paragraph shall not be required if an Event
of Default has occurred and is continuing. Subject to acceptance and recording thereof pursuant to
paragraph (d) of this Section, from and after the effective date specified in each Assignment and
Acceptance the assignee thereunder shall be a party hereto and, to the extent of the interest
assigned by such Assignment and Acceptance, have the rights and obligations of a Lender under this
Agreement, and the assigning Lender thereunder shall, to the extent of the interest assigned by
such Assignment and Acceptance, be released from its obligations under this Agreement (and, in the
case of an Assignment and Acceptance covering all of the assigning Lender’s rights and obligations
under this Agreement, such Lender shall cease to be a party hereto but shall continue to be
entitled to the benefits of Sections 2.15, 2.16, 2.17 and 9.03 as to matters occurring on or prior
to date of assignment). Any assignment or

67

 

transfer by a Lender of rights or obligations under this
Agreement that does not comply with this paragraph 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
paragraph (e) of this Section.

     (c) The Administrative Agent, acting for this purpose as an agent of the Borrower, shall
maintain at one of its offices in The City of New York, the address of which shall be made
available to any party to this Agreement upon request: a copy of each Assignment and Acceptance
delivered to it and a register for the recordation of the names and addresses of the Lenders, and
the Revolving Credit Commitment of, and principal amount of the Loans and LC Disbursements owing
to, each Lender pursuant to the terms hereof from time to time (the “Register”). The
entries in the Register shall be conclusive absent manifest error, and the Borrower, the
Administrative Agent, the Issuing Bank and the Lenders may treat each Person whose name is recorded
in the Register pursuant to the terms hereof as a Lender hereunder for all purposes of this
Agreement, notwithstanding notice to the contrary. In addition, the Administrative Agent shall
maintain on the Register information regarding the designation, and revocation of designation, of
any Lender as a Defaulting Lender. The Register shall be available for inspection by the Borrower,
the Issuing Bank and any Lender, at any reasonable time and from time to time upon reasonable prior
notice.

     (d) Upon its receipt of a duly completed Assignment and Acceptance executed by an assigning
Lender and an assignee, the assignee’s completed Administrative Questionnaire (unless the assignee
shall already be a Lender hereunder), the processing and recordation fee referred to in paragraph
(b) of this Section and any written consent to such assignment required by paragraph (b) of this
Section, the Administrative Agent shall accept such Assignment and Acceptance and record the
information contained therein in the Register. No assignment shall be effective for purposes of
this Agreement unless it has been recorded in the Register as provided in this paragraph.

     (e) Any Lender may, without the consent of the Borrower, the Administrative Agent, the Issuing
Bank or the Swingline Lender, sell participations to one or more banks or other entities, other
than a Defaulting Lender (a “Participant”) in all or a portion of such Lender’s rights and
obligations under this Agreement (including all or a portion of its Revolving Credit Commitment and
the Loans owing to it); provided that (i) such Lender’s obligations under this
Agreement shall remain unchanged, (ii) such Lender shall remain solely responsible to the other
parties hereto for the performance of such obligations and (iii) the Borrower, the Administrative
Agent, the Issuing Bank 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. Any agreement
or instrument pursuant to which a Lender sells such a participation shall provide that such Lender
shall retain the sole right to enforce this Agreement and to approve any amendment, modification or
waiver of any provision of this Agreement; provided that such agreement or
instrument may provide that such Lender will not, without the consent of the Participant, agree to
any amendment, modification or waiver described in the first proviso to Section 9.02(b) that
affects such Participant.

     (f) A Participant shall not be entitled to receive any greater payment under Section 2.15 or
2.17 than the applicable Lender would have been entitled to receive with respect to the
participation sold to such Participant, unless the sale of the participation to such Participant is
made with the Borrower’s prior written consent. A Participant that would be a Foreign Lender if it
were a Lender shall not be entitled to the benefits of Section 2.17 unless the Borrower is

68

 

notified of the participation sold to such Participant and such Participant agrees, for the benefit of the
Borrower, to comply with Section 2.17(e) as though it were a Lender and has zero withholding at the
time of participation.

     (g) Any Lender may at any time pledge or assign a security interest in all or any portion of
its rights under this Agreement to secure obligations of such Lender to a Federal Reserve Bank or
any central bank having jurisdiction over such Lender, and this Section shall not apply to any such
pledge or assignment of a security interest; provided that no such pledge or
assignment of a security interest shall release a Lender from any of its obligations hereunder or
substitute any such pledgee or assignee for such Lender as a party hereto.

     (h) In connection with any assignment of rights and obligations of any Defaulting Lender
hereunder, no such assignment shall be effective unless and until, in addition to the other
conditions thereto set forth herein, the parties to the assignment shall make such additional
payments to the Administrative Agent in an aggregate amount sufficient, upon distribution thereof
as appropriate (which may be outright payment, purchases by the assignee of participations or
subparticipations, or other compensating actions, including funding, with the consent of the
Borrower and the Administrative Agent, the applicable pro rata share of Revolving Loans previously
requested but not funded by the Defaulting Lender, to each of which the applicable assignee and
assignor hereby irrevocably consent), to (x) pay and satisfy in full all payment liabilities then
owed by such Defaulting Lender to the Administrative Agent or any Lender hereunder (and interest
accrued thereon) and (y) acquire (and fund as appropriate) its full pro rata share of all Revolving
Loans and participations in Letters of Credit and Swingline Loans in accordance with its Applicable
Revolving Credit Percentage. Notwithstanding the foregoing, in the event that any assignment of
rights and obligations of any Defaulting Lender hereunder shall become effective under applicable
Law without compliance with the provisions of this paragraph, then the assignee of such interest
shall be deemed to be a Defaulting Lender for all purposes of this Agreement until such compliance
occurs.

     SECTION 9.05. Survival. All covenants, agreements, representations and warranties
made by the Borrower herein and in the certificates or other instruments delivered in connection
with or pursuant to this Agreement shall be considered to have been relied upon by the other
parties hereto and shall survive the execution and delivery of this Agreement and the making of any
Loans and issuance of any Letters of Credit, regardless of any investigation made by any such other
party or on its behalf and notwithstanding that the Administrative Agent, the Issuing Bank or any
Lender may have had notice or knowledge of any Default or incorrect representation or warranty at
the time any credit is extended hereunder, and shall continue in full force and effect as long as
the principal of or any accrued interest on any Loan or any fee or any other amount payable under
this Agreement is outstanding and unpaid or any Letter of Credit is outstanding and so long as the
Revolving Credit Commitments have not expired or terminated. The provisions of Sections 2.15,
2.16, 2.17 and 9.03 and Article VIII shall survive and remain in full force and effect regardless
of the consummation of the transactions contemplated hereby, the repayment of the Loans, the
expiration or termination of the Letters of Credit and the Revolving Credit Commitments or the
termination of this Agreement or any provision hereof.

     SECTION 9.06. Counterparts; Integration; Effectiveness. This Agreement may be
executed in counterparts (and by different parties hereto on different counterparts), each of which
shall constitute an original, but all of which when taken together shall constitute a single
contract. This Agreement and any separate letter agreements with respect to fees payable to the

69

 

Administrative Agent constitute the entire contract among the parties relating to the subject
matter hereof and supersede any and all previous agreements and understandings, oral or
written, relating to the subject matter hereof. This Agreement shall become effective on the
Effective Date, and thereafter shall be binding upon and inure to the benefit of the parties hereto
and their respective successors and assigns. Delivery of an executed counterpart of a signature
page of this Agreement by telecopy shall be effective as delivery of a manually executed
counterpart of this Agreement.

     SECTION 9.07. Severability. Any provision of this Agreement held to be invalid,
illegal or unenforceable in any jurisdiction shall, as to such jurisdiction, be ineffective to the
extent of such invalidity, illegality or unenforceability without affecting the validity, legality
and enforceability of the remaining provisions hereof; and the invalidity of a particular provision
in a particular jurisdiction shall not invalidate such provision in any other jurisdiction.
Without limiting the foregoing provisions of this Section, if and to the extent that the
enforceability of any provisions in this Agreement relating to Defaulting Lenders shall be limited
by bankruptcy, insolvency, receivership or similar law, as determined in good faith by the
Administrative Agent, an Issuing Bank or the Swingline Lender, as applicable, then such provisions
shall be deemed to be in effect only to the extent not so limited.

     SECTION 9.08. Right of Setoff. If an Event of Default shall have occurred and be
continuing and acceleration has occurred under Article VII, each Lender and each of its Affiliates
is hereby authorized at any time and from time to time, to the fullest extent permitted by law, to
set off and apply any and all deposits (general or special, time or demand, provisional or final)
at any time held and other obligations at any time owing by such Lender or Affiliate to or for the
credit or the account of the Borrower against any of and all the obligations of the Borrower now or
hereafter existing under this Agreement held by such Lender, irrespective of whether or not such
Lender shall have made any demand under this Agreement and although such obligations may be
unmatured; provided, that in the event that any Defaulting Lender shall exercise any such
right of setoff granted hereunder, (x) all amounts so set off shall be paid over immediately to the
Administrative Agent for further application in accordance with the provisions of Section 2.18 and,
pending such payment, shall be segregated by such Defaulting Lender from its other funds and deemed
held in trust for the benefit of the Administrative Agent and the Lenders, and (y) the Defaulting
Lender shall provide promptly to the Administrative Agent a statement describing in reasonable
detail the obligations under this Agreement owing to such Defaulting Lender as to which it
exercised such right of setoff. The rights of each Lender under this Section are in addition to
other rights and remedies (including other rights of setoff) which such Lender may have.

     SECTION 9.09. Governing Law; Jurisdiction; Consent to Service of Process. (a) This
Agreement shall be construed in accordance with and governed by the law of the State of New York.

     (b) The Borrower hereby irrevocably and unconditionally submits, for itself and its property,
to the nonexclusive jurisdiction of the Supreme Court of the State of New York sitting in New York
County and of the United States District Court of the Southern District of New York, and any
appellate court from any thereof, in any action or proceeding arising out of or relating to this
Agreement, or for recognition or enforcement of any judgment, and each of the parties hereto hereby
irrevocably and unconditionally agrees that all claims in respect of any such action or proceeding may be heard and determined in such New York State or, to the extent

70

 

permitted by law, in such Federal court. Each of the parties hereto agrees that a final judgment
in any such action or proceeding shall be conclusive and may be enforced in other jurisdictions by
suit on the judgment or in any other manner provided by law. Nothing in this Agreement shall
affect any right that the Administrative Agent, the Issuing Bank or any Lender may otherwise have
to bring any action or proceeding relating to this Agreement against the Borrower or its properties
in the courts of any jurisdiction.

     (c) The Borrower hereby irrevocably and unconditionally waives, to the fullest extent it may
legally and effectively do so, any objection which 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 in any court
referred to in paragraph (b) of this Section. 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.

     (d) Each party to this Agreement irrevocably consents to service of process in the manner
provided for notices in Section 9.01. Nothing in this Agreement will affect the right of any party
to this Agreement to serve process in any other manner permitted by law.

     SECTION 9.10. WAIVER OF JURY TRIAL. EACH PARTY HERETO HEREBY WAIVES, TO THE FULLEST
EXTENT PERMITTED BY APPLICABLE LAW, ANY RIGHT IT MAY HAVE TO A TRIAL BY JURY IN ANY LEGAL
PROCEEDING DIRECTLY OR INDIRECTLY ARISING OUT OF OR RELATING TO THIS AGREEMENT OR THE TRANSACTIONS
CONTEMPLATED HEREBY (WHETHER BASED ON CONTRACT, TORT OR ANY OTHER THEORY). EACH PARTY HERETO (A)
CERTIFIES THAT NO REPRESENTATIVE, AGENT OR ATTORNEY OF ANY OTHER PARTY HAS REPRESENTED, EXPRESSLY
OR OTHERWISE, THAT SUCH OTHER PARTY WOULD NOT, IN THE EVENT OF LITIGATION, SEEK TO ENFORCE THE
FOREGOING WAIVER AND (B) ACKNOWLEDGES THAT IT AND THE OTHER PARTIES HERETO HAVE BEEN INDUCED TO
ENTER INTO THIS AGREEMENT BY, AMONG OTHER THINGS, THE MUTUAL WAIVERS AND CERTIFICATIONS IN THIS
SECTION.

     SECTION 9.11. Headings. Article and Section headings and the Table of Contents used
herein are for convenience of reference only, are not part of this Agreement and shall not affect
the construction of, or be taken into consideration in interpreting, this Agreement.

     SECTION 9.12. Confidentiality. Each of the Administrative Agent, the Co-Syndication
Agents, the Co-Documentation Agents, and the Lenders agrees to maintain the confidentiality of the
Information (as defined below), except that Information may be disclosed (a) to its and its
Affiliates’ directors, officers, employees and agents, including accountants, legal counsel and
other advisors (it being understood that the Persons to whom such disclosure is made will be
informed of the confidential nature of such Information and instructed to keep such Information
confidential), (b) to the extent requested by any regulatory authority, (c) to the extent required
by applicable laws or regulations or by any subpoena or similar legal process, (d) to any other
party to this Agreement, (e) 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, (f) subject
to an agreement containing provisions substantially the same as those of this Section, to any
assignee of or Participant in, or any prospective assignee of or Participant in, any of its rights
or obligations under this Agreement (including any pledgee or assignee permitted under Section
9.04(g)), (g) with the consent of the Borrower or (h) to the extent such Information (i) becomes

71

 

publicly available other than as a result of a breach of this Section or (ii) becomes available to
the Administrative Agent, Co-Syndication Agents, the Co-Documentation Agents or any Lender on a
nonconfidential basis from a source other than the Borrower and its Related Parties. For the
purposes of this Section, “Information” means all information received from the Borrower relating
to the Borrower or its business, other than any such information that is available to the
Administrative Agent or any Lender on a nonconfidential basis prior to disclosure by the Borrower.

     SECTION 9.13. Interest Rate Limitation. Notwithstanding anything herein to the
contrary, if at any time the interest rate applicable to any Loan, together with all fees, charges
and other amounts which are treated as interest on such Loan under applicable law (collectively the
“Charges”), shall exceed the maximum lawful rate (the “Maximum Rate”) which may be
contracted for, charged, taken, received or reserved by the Lender holding such Loan in accordance
with applicable law, the rate of interest payable in respect of such Loan hereunder, together with
all Charges payable in respect thereof, shall be limited to the Maximum Rate and, to the extent
lawful, the interest and Charges that would have been payable in respect of such Loan but were not
payable as a result of the operation of this Section shall be cumulated and the interest and
Charges payable to such Lender in respect of other Loans or periods shall be increased (but not
above the Maximum Rate therefor) until such cumulated amount, together (to the extent lawful) with
interest thereon at the Federal Funds Effective Rate to the date of repayment, shall have been
received by such Lender.

     SECTION 9.14. Liability of General Partner. It is hereby understood and agreed that
the General Partner shall have no personal liability, as general partner or otherwise, for the
payment of any amount owing or to be owing hereunder.

     SECTION 9.15. USA Patriot Act Notice. Each Lender and Agent (for itself and not on
behalf of any Lender) hereby notifies Borrower that pursuant to the requirements of the USA Patriot
Act (Title III of Pub. L. 107-56 (signed into law October 26, 2003)) (the “Act”), it is
required to obtain, verify and record information that identifies Borrower, which information
includes the name and address of Borrower and other information that will allow such Lender or the
Agent, as applicable, to identify Borrower in accordance with the Act. The Borrower
shall, following a request by the Agent or any Lender, provide all documentation and other
information that the Agent or such Lender reasonably requests in order to comply with its ongoing
obligations under applicable “know your customer” and anti-money laundering rules and regulations,
including the Act.

     SECTION 9.16. No Advisory or Fiduciary Responsibility. In connection with all
aspects of each transaction contemplated hereby (including in connection with any amendment, waiver
or other modification hereof or of any other Loan Document), Borrower acknowledges and agrees, and
acknowledges its Affiliates’ understanding, that: (i) (A) the arranging and other services
regarding this Agreement provided by Administrative Agent, arrangers and Lenders are arm’s-length
commercial transactions between Borrower and its Affiliates, on the one hand, and Administrative Agent, arrangers and Lenders, on the other hand, (B) Borrower has consulted
its own legal, accounting, regulatory and tax advisors to the extent it has deemed appropriate, and
(C) Borrower is capable of evaluating, and understands and accepts, the terms, risks and conditions
of the transactions contemplated hereby and by the other Loan Documents; (ii) (A) Administrative
Agent, each Lender and each arranger is and has been acting solely as a principal and, except as
expressly agreed in writing by the relevant parties, has not been, is not, and will

72

 

not be acting as an advisor, agent or fiduciary for Borrower or any of its Affiliates, or any other Person and
(B) neither Administrative Agent nor any arranger or Lender has any obligation to Borrower or any
of its Affiliates with respect to the transactions contemplated hereby except those obligations
expressly set forth herein and in the other Loan Documents; and (iii) Administrative Agent,
arrangers and Lenders and their respective Affiliates may be engaged in a broad range of
transactions that involve interests that differ from those of Borrower and its Affiliates, and
neither Administrative Agent, any arranger or any Lender has any obligation to disclose any of such
interests to Borrower or its Affiliates. To the fullest extent permitted by law, Borrower hereby
waives and releases any claims that it may have against Administrative Agent, any arranger or any
Lender with respect to any breach or alleged breach of agency or fiduciary duty in connection with
any aspect of any transaction contemplated hereby.

     SECTION 9.17. Existing Credit Facility. Each Lender and Administrative Agent (for
the undersigned Lenders, to the extent a party to the Existing Credit Facility) agree and
acknowledge that in connection with the amendment and restatement of the Existing Credit Facility
pursuant hereto, Borrower, Administrative Agent and Lenders shall make adjustments to (i) the
outstanding principal amount of “Revolving Loans” (as defined in the Existing Credit Facility) (but
not any interest accrued thereon prior to the Effective Date or any accrued facility fees under the
Existing Credit Facility prior to the Effective Date), including the borrowing of such additional “
Revolving Loans” (which may include “Eurodollar Loans” (as defined in the Existing Credit Facility)
and the repayment of “Revolving Loans” (which may include the prepayment or conversion of
“Eurodollar Loans”) plus all applicable accrued interest, fees and expenses as shall be necessary
to provide for Revolving Loans by each Lender in the amount of its new Applicable Revolving Credit
Percentage of all Revolving Loans as of the Effective Date, and (ii) participations in Existing
Letters of Credit to provide for each Lender’s participation in each Existing Letter of Credit
equal to such Lender’s new Applicable Revolving Credit Percentage of the aggregate amount available
to be drawn under each such Existing Letter of Credit as of the Effective Date. In connection with
the foregoing, each Lender shall be deemed to have made an assignment of its outstanding Revolving
Loans and “Commitments” (as defined in the Existing Credit Facility) under the Existing Credit
Facility, and assumed outstanding Revolving Loans and Commitments of other Lenders under the
Existing Credit Facility, all at the request of the Borrower, as may be necessary to effect the
foregoing, and each such Lender shall be entitled to any reimbursement under Section 2.16 hereof
with respect thereto. Each of the undersigned Lenders, to the extent a party to the Existing Credit
Facility, waives any requirement under the Existing Credit Facility that notice with respect to any
such borrowing, prepayment or other transaction described in this Section 9.16 be given.

(ii) a $7.5 million Subordinated Note Payable to The Louisiana Land and Exploration Company
(or any successor or assign), dated December 31, 1991, made by Evangeline Gas Pipeline

     DUNCAN ENERGY PARTNERS L.P., a Delaware limited partnership (the “Borrower”), for
value received, promises and agrees to pay to WELLS FARGO BANK, NATIONAL ASSOCIATION, as Swingline

MILLION AND NO/100 DOLLARS ($75,000,000.00), or such lesser amount as shall equal the aggregate
unpaid principal amount of the Swingline Loans owed to the Swingline Lender under the Credit
Agreement, in lawful money of the United States of America and in immediately available funds, on
the dates and in the principal amounts provided in the Credit Agreement, and to pay interest on the
unpaid principal amount as provided in the Credit Agreement for such Swingline Loans, at such
office, in like money and funds, for the period commencing on the date of each such Swingline Loan
until such Swingline Loan shall be paid in full, at the rates per annum and on the dates provided
in the Credit Agreement.

     This note evidences the Swingline Loans owed to the Swingline Lender under that certain
Revolving Credit and Term Loan Agreement dated as of October 25, 2010, by and among the Borrower,
Wells Fargo Bank, National Association, individually, as Administrative Agent, Issuing Bank and
Swingline Lender, and the other financial institutions parties thereto (such Credit Agreement,
together with all amendments or supplements thereto, being the “Credit Agreement”), and
shall be governed by the Credit Agreement. Capitalized terms used in this note and not defined in
this note, but which are defined in the Credit Agreement, have the respective meanings herein as
are assigned to them in the Credit Agreement.

     The Swingline Lender is hereby authorized by the Borrower to endorse on Schedule A (or a
continuation thereof) attached to this note, the amount and date of each payment or prepayment of
principal of each such Swingline Loan received by the Swingline Lender, provided that any failure
by the Swingline Lender to make any such endorsement shall not affect the obligations of the
Borrower under the Credit Agreement or under this note in respect of such Swingline Loans.

     This note may be held by the Swingline Lender for the account of its applicable lending office
and, except as otherwise provided in the Credit Agreement, may be transferred from one lending
office of the Swingline Lender to another lending office of the Swingline Lender from time to time
as the Swingline Lender may determine.

     Except only for any notices which are specifically required by the Credit Agreement, the
Borrower and any and all co-makers, endorsers, guarantors and sureties severally waive notice
(including but not limited to notice of intent to accelerate and notice of acceleration, notice of
protest and notice of dishonor), demand, presentment for payment, protest, diligence in collecting
and the filing of suit for the purpose of fixing liability, and consent that the time of payment
hereof may be extended and re-extended from time to time without notice to any of them. Each such
person agrees that its liability on or with respect to this note shall not be

affected by any release of or change in any guaranty or security at any time existing or by
any failure to perfect or maintain perfection of any lien against or security interest in any such
security or the partial or complete unenforceability of any guaranty or other surety obligation, in
each case in whole or in part, with or without notice and before or after maturity.

     The Credit Agreement provides for the acceleration of the maturity of this note upon the
occurrence of certain events and for prepayment of Swingline Loans upon the terms and conditions
specified therein. Reference is made to the Credit Agreement for all other pertinent purposes.

     This note is issued pursuant to and is entitled to the benefits of the Credit Agreement.

     It is hereby understood and agreed that DEP Holdings, LLC, the general partner of the

amount owing or to be owing hereunder.

     This note shall be construed in accordance with and be governed by the law of the State of
New York and the United States of America from time to time in effect.
