maintained by such Bank and by the Administrative Agent in the ordinary course of business. The
accounts or records maintained by the Administrative Agent and each Bank shall be conclusive absent
manifest error of the amount of the Advances made by the Banks to the Borrower and the interest and
payments thereon. Any failure to so record or any error in doing so shall not, however, limit or
otherwise affect the obligation of the Borrower hereunder to pay any amount owing with respect to
the Obligations. In the event of any conflict between the accounts and records maintained by any
Bank and the accounts and records of the Administrative Agent in respect of such matters, the
accounts and records of the Administrative Agent shall control in the absence of manifest error.

Borrowing comprised of Eurodollar Rate Advances, the Administrative Agent shall promptly notify

receipt of a Notice of Conversion or Continuation under this Section, the Administrative Agent
shall provide each Bank with a copy thereof and, in the case of a Conversion to or a Continuation
of a Borrowing comprised of Eurodollar Rate Advances, notify each Bank of the applicable interest
rate under Section 2.07(b). No such Conversion or continuation shall be deemed the making of a new
Advance for purposes of this Agreement, including without limitation Article III.

          (c) Certain Limitations. Notwithstanding anything in paragraphs (a) and (b) above:

               (i) at no time shall there be more than six Interest Periods applicable to outstanding
Eurodollar Rate Advances and the Borrower may not select Eurodollar Rate Advances for any Borrowing
at any time that a Default has occurred and is continuing;

               (ii) if any Bank shall at least one Business Day before the date of any requested Borrowing,
Conversion or continuation, notify the Administrative Agent that the introduction of or any change
in or in the interpretation of any law or regulation makes it unlawful, or that any central bank or
other Governmental Person asserts that it is unlawful, for such Bank or its Eurodollar Lending
Office to perform its obligations under this Agreement to make Eurodollar Rate Advances or to fund
or maintain Eurodollar Rate Advances, the right of the Borrower to select Eurodollar Rate Advances
from such Bank shall be suspended until such Bank shall notify the Administrative Agent that the
circumstances causing such suspension no longer exist, and the Advance made by such Bank in respect
of such Borrowing, Conversion or continuation shall be a Reference Rate Advance;

               (iii) if the Administrative Agent is unable to determine in good faith the Eurodollar Rate for
Eurodollar Rate Advances comprising any requested Borrowing, the right of the Borrower to select
Eurodollar Rate Advances for such Borrowing or for any subsequent Borrowing shall be suspended
until the Administrative Agent shall notify the Borrower and the Banks that the circumstances
causing such suspension no longer exist, and each Advance comprising such Borrowing shall be a
Reference Rate Advance;

               (iv) if the Majority Banks shall, at least one Business Day before the date of any requested
Borrowing, notify the Administrative Agent that the Eurodollar Rate for Eurodollar Rate Advances
comprising such Borrowing will not adequately reflect the cost to

-24-

 

such Banks of making or funding their respective Eurodollar Rate Advances, as the case may be,
for such Borrowing, the right of the Borrower to select Eurodollar Rate Advances for such Borrowing
or for any subsequent Borrowing shall be suspended until the Administrative Agent shall notify the
Borrower and the Banks that the circumstances causing such suspension no longer exist, and each
Advance comprising such Borrowing shall be a Reference Rate Advance; and

               (v) if the Borrower shall fail to select the duration or continuation of any Interest Period
for any Eurodollar Rate Advances in accordance with the provisions contained in the definition of
“Interest Period” in Section 1.01 and paragraph (b) above, the Administrative Agent shall so notify
the Borrower and the Banks and such Advances shall be made available to the Borrower on the date of
such Borrowing as Reference Rate Advances or, if an existing Advance, Converted into Reference Rate
Advances.

          (d) Notices Irrevocable. Each Notice of Borrowing and Notice of Conversion or
Continuation, once delivered, shall be irrevocable and binding on the Borrower. In the case of any
Borrowing which the related Notice of Borrowing specifies is to be comprised of Eurodollar Rate
Advances, the Borrower shall indemnify each Bank against any loss, out-of-pocket cost or expense
incurred by such Bank as a result of any failure by the Borrower to fulfill on or before the date
specified in such Notice of Borrowing, the applicable conditions set forth in Article III,
including, without limitation, any loss (including any loss of anticipated profits), cost or
expense incurred by reason of the liquidation or reemployment of deposits or other funds acquired
by such Bank to fund the Advance to be made by such Bank as part of such Borrowing when such
Advance, as a result of such failure, is not made on such date.

          (e) Funding by Banks; Presumption by Administrative Agent. Unless the Administrative
Agent shall have received notice from a Bank prior to the proposed date of any Borrowing that such
Bank will not make available to the Administrative Agent such Bank’s share of such Borrowing, the
Administrative Agent may assume that such Bank has made such share available on such date in
accordance with Section 2.02 and may, in reliance upon such assumption, make available to the
Borrower a corresponding amount. In such event, if a Bank has not in fact made its share of the
applicable Borrowing available to the Administrative Agent, then the applicable Bank and the
Borrower severally agree to pay to the Administrative Agent forthwith on demand such corresponding
amount in immediately available funds 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 (a) in the case of a payment to be made by such Bank, the greater of the
Federal Funds Rate and a rate determined by the Administrative Agent in accordance with banking
industry rules on interbank compensation and (B) in the case of a payment to be made by the
Borrower, the interest rate applicable to Reference Rate Advances. If the Borrower and such Bank
shall pay such interest to the Administrative Agent for the same or an overlapping period, the
Administrative Agent shall promptly remit to the Borrower the amount of such interest paid by the
Borrower for such period. If such Bank pays its share of the applicable Borrowing to the
Administrative Agent, then the amount so paid shall constitute such Bank’s Advance included in such
Borrowing. Any payment by the Borrower shall be without prejudice to any claim the Borrower may
have against a Bank that shall have failed to make such payment to the Administrative Agent. A
notice of the

-25-

 

Administrative Agent to any Bank or the Borrower with respect to any amount owing under this
subsection (e) shall be conclusive, absent manifest error.

          (f) Obligations of Banks Several. The obligations of the Banks hereunder to make
Advances, to fund participations in Letters of Credit and to make payments pursuant to Section
9.04(c) are several and not joint. The failure of any Bank to make any Advance, to fund any
such participation or to make any payment under Section 9.04(c) on any date required
hereunder shall not relieve any other Bank of its corresponding obligation to do so on such date,
and no Bank shall be responsible for the failure of any other Bank to so make its Advance, to
purchase its participation or to make its payment under Section 9.04(c).

     Section 2.03. Reduction of the Commitments.

          (a) The Borrower shall have the right, upon at least three Business Days’ irrevocable notice
to the Administrative Agent, to terminate in whole or reduce ratably in part the unused portion of
the Commitments; provided that (i) each partial reduction shall be in the aggregate amount of
$1,000,000 or an integral multiple of $500,000 and (ii) the Borrower shall not terminate or reduce
the aggregate Commitments if, after giving effect thereto and to any concurrent prepayments
hereunder, the aggregate amount of Advances plus the Letter of Credit Exposure would exceed the
aggregate Commitments.

          (b) Any reduction and termination of the Commitments pursuant to this Section 2.03 shall be
applied ratably to each Bank’s Commitment and shall be permanent, with no obligation of the Banks
to reinstate such Commitments and the commitment fees provided for in Section 2.06(a) shall
thereafter be computed on the basis of the Commitments, as so reduced.

     Section 2.04. Prepayment of Advances.

          (a) Optional. The Borrower may prepay all Advances at any time, without premium or
penalty, after giving by 12:00 p.m. (i) in the case of Eurodollar Rate Advances, at least three
Business Days’ or (ii) in case of Reference Rate Advances, on the same Business Day, irrevocable
prior written notice to the Administrative Agent stating the proposed date and aggregate principal
amount of such prepayment. If any such notice is given, the Borrower shall prepay Advances
comprising part of the same Borrowing in whole or ratably in part in an aggregate principal amount
equal to the amount specified in such notice, together with accrued interest to the date of such
prepayment on the principal amount prepaid and amounts, if any, required to be paid pursuant to
Section 2.10 as a result of such prepayment being made on such date; provided,
however, that each partial prepayment with respect to: (a) any Borrowing comprised of
Reference Rate Advances shall be made in an initial minimum aggregate principal amount of $500,000
and thereafter in $100,000 multiples and in an aggregate principal amount such that after giving
effect thereto such Borrowing shall have a principal amount outstanding of at least $500,000 and
(b) any Borrowing comprised of Eurodollar Rate Advances shall be made in an initial minimum
aggregate principal amount of $1,000,000 and thereafter in $500,000 multiples and in an aggregate
principal amount such that after giving effect thereto such Borrowing shall have a principal amount
outstanding of at least $1,000,000. Full prepayments of any Borrowing are permitted without
restriction of amounts. Each prepayment under this Section 2.04(a) shall be allocated between the
Advances as determined by the Borrower.

-26-

 

          (b) Mandatory.

               (i) Reduction of Commitments. On the date of each reduction of the aggregate
Commitments pursuant to Section 2.03 or if for any reason the outstanding amount of Advances plus
the Letter of Credit Exposure exceeds the aggregate Commitments then in effect, the Borrower agrees
to make a prepayment in respect of the outstanding amount of the Advances and/or Cash Collateralize
the Letter of Credit Obligations to the extent, if any, that the aggregate unpaid principal amount
of all Advances plus the Letter of Credit Exposure exceeds the Commitments.

               (ii) Asset Disposition. If the Borrower or any of its Subsidiaries shall receive Net
Cash Proceeds from any Asset Disposition in excess of $20,000,000 or any Recovery Event in excess
of $20,000,000 (except (i) to the extent that a Reinvestment Notice shall be delivered in respect
of such Asset Disposition or Recovery Event or (ii) with respect to cash receipts in the ordinary
course of business of the applicable recipient), then on the date of receipt by the Borrower or the
applicable Subsidiary of such Net Cash Proceeds, the Advances shall immediately be prepaid by an
amount equal to the amount of such Net Cash Proceeds (except to the extent such Net Cash Proceeds
are otherwise required by the Note Agreement to be applied to the ratable prepayment of the Note
Obligations); provided, that, notwithstanding the foregoing, on each Reinvestment
Prepayment Date the Advances shall be prepaid by an amount equal to the Reinvestment Prepayment
Amount with respect to the relevant Reinvestment Event (except to the extent such Reinvestment
Prepayment Amount is otherwise required by the Note Agreement to be applied to the ratable
prepayment of the Note Obligations). For purposes of calculating whether the Net Cash Proceeds
received from an Asset Disposition exceed $20,000,000 or from a Recovery Event exceed $20,000,000,
such proceeds shall be determined as of the date of the applicable Asset Disposition or Recovery
Event, whether or not received on such date, but no such amount shall be required to be applied to
prepayment of the Advances pursuant to this Section until received by the applicable Person. The
provisions of this Section do not constitute a consent to the consummation of any Disposition not
permitted by Section 6.04.

               (iii) Debt Issuance. If any Debt for borrowed money shall be issued or incurred by
the Borrower or any of its Subsidiaries (excluding any Debt incurred in accordance with Section
6.02), then on the date of such issuance or incurrence, the Advances shall be prepaid by an
amount equal to the amount of the Net Cash Proceeds of such issuance or incurrence, except to the
extent that such Net Cash Proceeds are otherwise required by the Note Agreement to be applied to
the ratable prepayment of the Note Obligations. The provisions of this Section do not constitute a
consent to the issuance or incurrence of any Debt by the Borrower or any of its Subsidiaries not
otherwise permitted hereunder.

               (iv) Accrued Interest. Each prepayment under this Section 2.04(b) shall be
accompanied by accrued interest on the amount prepaid to the date of such prepayment and amounts,
if any, required to be paid pursuant to Section 2.10 as a result of such prepayment.

          (c) Illegality. If any Bank shall notify the Administrative Agent and the Borrower
that the introduction of or any change in or in the interpretation of any law or regulation makes
it unlawful, or that any central bank or other Governmental Person asserts that

-27-

 

it is unlawful for such Bank or its Eurodollar Lending Office to perform its obligations under
this Agreement to maintain any Eurodollar Rate Advances of such Bank then outstanding hereunder,
(i) the Borrower shall (a) if not prohibited by law, on the last day of the Interest Period for
each outstanding Eurodollar Rate Advance made by such Bank or (b) if required by such notice, on
the second Business Day following its receipt of such notice prepay all of the Eurodollar Rate
Advances made by such Bank then outstanding, together with accrued interest on the principal amount
prepaid to the date of such prepayment and amounts, if any, required to be paid pursuant to Section
2.10 as a result of such prepayment being made on such date, (ii) such Bank shall simultaneously
make a Reference Rate Advance to the Borrower on such date in an amount equal to the aggregate
principal amount of the Eurodollar Rate Advances prepaid to such Bank, and (iii) the right of the
Borrower to select Eurodollar Rate Advances from such Bank for any subsequent Borrowing shall be
suspended until such Bank shall notify the Administrative Agent that the circumstances causing such
suspension no longer exist; provided, that such Bank agrees to use reasonable efforts to
designate a different Applicable Lending Office if the making of such designation would avoid such
payment, and would not, in its reasonable judgment, be otherwise disadvantageous to such Bank.

          (d) No Additional Right; Ratable Prepayment. The Borrower shall have no right to
prepay any principal amount of any Advance except as provided in this Section 2.04, and all notices
given pursuant to this Section 2.04 shall be irrevocable and binding upon the Borrower. Each
payment of any Advance pursuant to this Section 2.04 shall be made in a manner such that all
Advances comprising part of the same Borrowing are paid in whole or ratably in part.

     Section 2.05. Repayment of Advances. The Borrower shall repay the outstanding
principal amount of the Advances outstanding on the Termination Date.

     Section 2.06. Fees.

          (a) Commitment Fees.

               (i) The Borrower agrees to pay to the Administrative Agent for the account of each Bank a
commitment fee on the daily amount by which such Bank’s Commitment exceeds the sum of (a) such
Bank’s outstanding Advances and (b) such Bank’s Pro Rata Share of the Letter of Credit Exposure, at
the Applicable Margin for commitment fees from the date of this Agreement until the Termination
Date. The commitment fees shall be due and payable quarterly in arrears on the last day of each
March, June, September and December prior to the Termination Date and on the Termination Date.

          (b) Agent Fees. The Borrower agrees to pay to the Administrative Agent for the
benefit of the Administrative Agent or the Lead Arranger, as applicable, the fees described in the
letter dated as of February 8, 2005 from Bank of America and the Lead Arranger to the Borrower (the
“Fee Letter”).

          (c) Letter of Credit Fees.

               (i) With respect to each Financial Letter of Credit issued hereunder, the Borrower agrees to
pay to (a) the Administrative Agent for the pro rata benefit of the Banks a

-28-

 

fee per annum equal to the Applicable Margin for letter of credit fees on the aggregate amount
available for drawing from time to time under such Financial Letter of Credit and (b) to the
Issuing Bank a facing fee for each Letter of Credit of .125% per annum of the face amount of such
Letter of Credit. Each such fee shall be payable quarterly in arrears on the last day of each
March, June, September and December prior to the Termination Date and on the Termination Date (or,
if later, the date on which all outstanding Letters of Credit have expired).

               (ii) With respect to each Performance Letter of Credit issued hereunder, the Borrower agrees
to pay to (a) the Administrative Agent for the pro rata benefit of the Banks a one-time letter of
credit fee in an amount equal to the Applicable Margin for letter of credit fees on the initial
stated amount of such Performance Letter of Credit (or, with respect to any subsequent increase to
the stated amount of any such Performance Letter of Credit, such increase in the stated amount)
thereof, such fee to be payable on the date of such issuance, increase or extension and (b) to the
Issuing Bank a facing fee for each Letter of Credit of .125% per annum of the face amount of such
Letter of Credit, payable in advance, commencing on the date of issuance, increase or extension of
such Letter of Credit and quarterly thereafter.

               (iii) The Borrower agrees to pay concurrently with each issuance, negotiation, drawing, or
amendment of each Letter of Credit, to the Issuing Bank for the sole account of the Issuing Bank,
issuance, negotiation, drawing and amendment fees and other standard costs and charges in the
amounts set forth from time to time as the Issuing Bank’s published scheduled fees for such
services.

     Section 2.07. Interest. The Borrower shall pay interest on the unpaid principal
amount of each Advance made by each Bank from the date of such Advance until such principal amount
shall be paid in full, at the following rates per annum:

          (a) Reference Rate Advances. If such Advance is a Reference Rate Advance, a rate per
annum equal at all times to the Adjusted Reference Rate in effect from time to time plus
the Applicable Margin in effect from time to time, payable in arrears on the last day of each
March, June, September and December and on the date such Reference Rate Advance shall be paid in
full, provided that upon the occurrence and during the continuance of any Event of Default,
such Advance shall bear interest at a rate per annum equal at all times to the Adjusted Reference
Rate in effect from time to time plus the Applicable Margin plus 2.00% per annum,
payable on demand.

          (b) Eurodollar Rate Advances. If such Advance is a Eurodollar Rate Advance, a rate
per annum equal at all times during the Interest Period for such Advance to the Eurodollar Rate for
such Interest Period plus the Applicable Margin in effect from time to time, payable on the
last day of such Interest Period, and, in the case of six-month Interest Periods, on the day which
occurs during such Interest Period three months from the first day of such Interest Period,
provided that upon the occurrence and during the continuance of any Event of Default, such
Advance shall bear interest at a rate per annum equal at all times during the Interest Period for
such Advance to the Eurodollar Rate for such Interest Period plus the Applicable Margin
plus 2.00% per annum, payable on demand.

-29-

 

          (c) Additional Interest on Eurodollar Rate Advances. The Borrower shall pay to each
Bank, so long as any such Bank shall be required under regulations of the Federal Reserve 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 Eurodollar Rate Advance of
such Bank, from the effective date of such Advance 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
Eurodollar Rate for the Interest Period for such Advance from (ii) the rate obtained by dividing
such Eurodollar Rate by a percentage equal to 100% minus the Eurodollar Rate Reserve Percentage of
such Bank for such Interest Period, payable on each date on which interest is payable on such
Advance. Such additional interest payable to any Bank shall be determined by such Bank and
notified to the Borrower through the Administrative Agent (such notice to include the calculation
of such additional interest, which calculation shall be conclusive in the absence of manifest
error).

          (d) Usury Recapture.

               (i) If, with respect to any Bank, the effective rate of interest contracted for under the
Credit Documents, including the stated rates of interest and fees contracted for hereunder and any
other amounts contracted for under the Credit Documents which are deemed to be interest, at any
time exceeds the Maximum Rate, then the outstanding principal amount of the loans made by such Bank
hereunder shall bear interest at a rate which would make the effective rate of interest for such
Bank under the Credit Documents equal the Maximum Rate until the difference between the amounts
which would have been due at the stated rates and the amounts which were due at the Maximum Rate
(the “Lost Interest”) has been recaptured by such Bank.

               (ii) If, when the loans made hereunder are repaid in full, the Lost Interest has not been
fully recaptured by such Bank pursuant to the preceding paragraph, then, to the extent permitted by
law, for the loans made hereunder by such Bank the interest rates charged under Section 2.07
hereunder shall be retroactively increased such that the effective rate of interest under the
Credit Documents was at the Maximum Rate since the effectiveness of this Agreement to the extent
necessary to recapture the Lost Interest not recaptured pursuant to the preceding sentence and, to
the extent allowed by law, the Borrower shall pay to such Bank the amount of the Lost Interest
remaining to be recaptured by such Bank.

               (iii) Notwithstanding the foregoing or any other term in this Agreement and the Credit
Documents to the contrary, it is the intention of each Bank and the Borrower to conform strictly to
any applicable usury laws. Accordingly, if any Bank contracts for, charges, or receives any
consideration which constitutes interest in excess of the Maximum Rate, then any such excess shall
be canceled automatically and, if previously paid, shall at such Bank’s option be applied to the
outstanding amount of the loans made hereunder by such Bank or be refunded to the Borrower.

     Section 2.08. Payments and Computations.

          (a) Payment Procedures. All payments to be made by the Borrower shall be made without
condition or deduction for any counterclaim, defense, recoupment or setoff. The

-30-

 

Borrower shall make each payment under this Agreement and under the Notes not later than 2:00
p.m. on the day when due in Dollars to the Administrative Agent at the Administrative Agent’s
Office in same day funds. The Administrative Agent shall promptly thereafter cause to be
distributed like funds relating to the payment of principal, interest or fees ratably (other than
amounts payable solely to the Administrative Agent, the Issuing Bank or a specific Bank pursuant to
Section 2.06(b), 2.06(c), 2.10, 2.11, 2.12, 2.13, or 9.04) in accordance with each Bank’s Pro Rata
Share to the Banks for the account of their respective Applicable Lending Offices, and like funds
relating to the payment of any other amount payable to any Bank or the Issuing Bank to such Bank
for the account of its Applicable Lending Office, in each case to be allocated between the Types of
Advances and applied in the manner determined by the Administrative Agent in its sole discretion.

          (b) Computations. All computations of interest based on the Reference Rate and of
fees shall be made by the Administrative Agent on the basis of a year of 365 or 366 days, as the
case may be, and all computations of interest based on the Eurodollar Rate and the Federal Funds
Rate shall be made by the Administrative Agent, on the basis of a year of 360 days, in each case
for the actual number of days (including the first day, but excluding the last day) occurring in
the period for which such interest or fees are payable. Each determination by the Administrative
Agent of an interest rate or fee shall be conclusive and binding for all purposes, absent manifest
error.

          (c) Non-Business Day Payments. Whenever any payment shall be stated to be due on a
day other than a Business Day, such payment shall be made on the next succeeding Business Day, and
such extension of time shall in such case be included in the computation of payment of interest or
fees, as the case may be.

          (d) Payments by Borrower; Presumptions by Administrative Agent. 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 Banks 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 Banks 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 Banks 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 Bank or the Issuing Bank, in immediately available
funds 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 Rate and a rate determined by the Administrative Agent in accordance with banking industry
rules on interbank compensation. A notice of the Administrative Agent to any Bank or the Borrower
with respect to any amount owing under this subsection (d) shall be conclusive, absent manifest
error.

     Section 2.09. Sharing of Payments, Etc. If any Bank shall obtain any payment (whether
voluntary, involuntary, through the exercise of any right of set-off, or otherwise) on account of
the Advances or Letter of Credit Obligations made by it in excess of its Pro Rata Share of payments
on account of the Advances or Letter of Credit Obligations obtained by all the Banks, such Bank
shall notify the Administrative Agent and forthwith purchase from the other Banks

-31-

 

such participations in the Advances made by them or Letter of Credit Obligations held by them
as shall be necessary to cause such purchasing Bank to share the excess payment ratably with each
of them; provided, however, that if all or any portion of such excess payment is
thereafter recovered from such purchasing Bank, such purchase from each Bank shall be rescinded and
such Bank shall repay to the purchasing Bank the purchase price to the extent of such Bank’s
ratable share (according to the proportion of (a) the amount of the participation sold by such Bank
to the purchasing Bank as a result of such excess payment to (b) the total amount of such excess
payment) of such recovery, together with an amount equal to such Bank’s ratable share (according to
the proportion of (i) the amount of such Bank’s required repayment to the purchasing Bank to (ii)
the total amount of all such required repayments to the purchasing Bank) of any interest or other
amount paid or payable by the purchasing Bank in respect of the total amount so recovered. The
Borrower agrees that any Bank so purchasing a participation from another Bank pursuant to this
Section 2.09 may, to the fullest extent permitted by law, exercise all its rights of payment
(including the right of set-off) with respect to such participation as fully as if such Bank were
the direct creditor of the Borrower in the amount of such participation.

     Section 2.10. Breakage Costs. If (a) any payment of principal of any Eurodollar Rate
Advance is made other than on the last day of the Interest Period for such Advance, whether as a
result of any payment pursuant to Section 2.04, the acceleration of the maturity of the Notes
pursuant to Article VII, or for any other reason or (b) the Borrower fails to make a principal or
interest payment with respect to any Eurodollar Rate Advance on the date such payment is due and
payable, the Borrower shall, within 10 days of any written demand sent by any Bank to the Borrower
through the Administrative Agent (which demand shall provide a statement explaining the amount and
setting forth the computation of any such loss or expense), pay to the Administrative Agent for the
account of such Bank any amounts required to compensate such Bank for any additional losses,
out-of-pocket costs or expenses which it may reasonably incur as a result of such payment or
nonpayment, including, without limitation, any loss (including loss of anticipated profits), cost
or expense incurred by reason of the liquidation or reemployment of deposits or other funds
acquired by any Bank to fund or maintain such Advance.

     Section 2.11. Increased Costs.

          (a) Eurodollar Rate Advances. If, due to either (i) the introduction of or any change
(other than any change by way of imposition or increase of reserve requirements included in the
Eurodollar Rate Reserve Percentage) in or in the interpretation of any law or regulation occurring
on or after the date of this Agreement or (ii) the compliance with any guideline or request from
any central bank or other Governmental Person (whether or not having the force of law), there shall
be any increase occurring on or after the date of this Agreement in the cost to any Bank of
agreeing to make or making, funding or maintaining Eurodollar Rate Advances, then the Borrower
shall from time-to-time, upon demand by such Bank (with a copy of such demand to the Administrative
Agent), immediately pay to the Administrative Agent for the account of such Bank additional amounts
sufficient to compensate such Bank for such increased cost; provided, that, before making
any such demand, such Bank agrees to promptly notify the Borrower and to use reasonable efforts
(consistent with its internal policy and legal and regulatory restrictions) to designate a
different Applicable Lending Office if the making of such a designation would avoid the need for,
or reduce the amount of, such increased cost and would not, in its reasonable judgment, be
otherwise disadvantageous. A certificate as to the amount of

-32-

 

such increased cost and detailing the calculation of such cost submitted to the Borrower and
the Administrative Agent by such Bank shall be conclusive and binding for all purposes, absent
manifest error.

          (b) Capital Adequacy. If any Bank or the Issuing Bank reasonably determines that its
required compliance with any law or regulation or any guideline or request from any central bank or
other Governmental Person (whether or not having the force of law) affects or would affect the
amount of capital required or expected to be maintained by such Bank or the Issuing Bank or any
corporation controlling such Bank or the Issuing Bank and that the amount of the capital is
increased by or based upon the existence of such Bank’s commitment to lend or the Issuing Bank’s
commitment to issue the Letters of Credit and other commitments of this type, then, upon 30 days’
prior written notice by such Bank or the Issuing Bank (with a copy of any such demand to the
Administrative Agent), the Borrower shall immediately pay to the Administrative Agent for the
account of such Bank or the Issuing Bank, as the case may be, from time-to-time as specified by
such Bank or the Issuing Bank, additional amounts sufficient to compensate such Bank or the Issuing
Bank, in light of the circumstances, to the extent that such Bank or the Issuing Bank, as the case
may be, reasonably determines the increase in capital to be allocable to the existence of such
Bank’s commitment to lend or the Issuing Bank’s commitment to issue the Letters of Credit under
this Agreement. A certificate as to the amounts showing in reasonable detail the calculation of
the amounts submitted to the Borrower by such Bank or the Issuing Bank shall be presumptively
correct, absent manifest error.

          (c) Letters of Credit. If any change in any law or regulation or in the
interpretation thereof by any court or administrative or Governmental Person charged with the
administration thereof shall either (i) impose, modify, or deem applicable any reserve, special
deposit, or similar requirement against letters of credit issued by, or assets held by, or deposits
in or for the account of, the Issuing Bank or (ii) impose on the Issuing Bank any other condition
regarding the provisions of this Agreement relating to the Letters of Credit or any Letter of
Credit Obligations, and the result of any event referred to in the preceding clause (i) or (ii)
shall be to increase the cost to the Issuing Bank of issuing or maintaining any Letter of Credit
(which increase in cost shall be determined by the Issuing Bank’s reasonable allocation of the
aggregate of such cost increases resulting from such event), then, upon demand by the Issuing Bank,
the Borrower shall pay to the Administrative Agent for the account of the Issuing Bank, from time
to time as specified by the Issuing Bank, additional amounts which shall be sufficient to
compensate the Issuing Bank for such increased cost. A certificate as to such increased cost
incurred by the Issuing Bank, as a result of any event mentioned in clause (i) or (ii) above, and
detailing the calculation of such increased costs submitted by the Issuing Bank to the Borrower,
shall be conclusive and binding for all purposes, absent manifest error.

     Section 2.12. Taxes.

          (a) No Deduction for Certain Taxes. Any and all payments by the Borrower shall be
made, in accordance with Section 2.08, free and clear of and without deduction for any and all
present or future taxes, levies, imposts, deductions, charges or withholdings, and all liabilities
with respect thereto, excluding, in the case of each Bank, the Issuing Bank and the Administrative
Agent, taxes imposed on its income, and franchise taxes imposed on it, by the jurisdiction (any
political subdivision of the jurisdiction) under the laws of which such Bank, the

-33-

 

Issuing Bank or the Administrative Agent (as the case may be) is organized or maintains its
Applicable Lending Office (all such income and franchise taxes collectively referred to as
“Excluded Taxes”, and all such taxes, levies, imposts, deductions, charges, withholdings
and liabilities, other than the Excluded Taxes being hereinafter referred to as “Taxes”).
If the Borrower shall be required by law to deduct any Taxes from or in respect of any sum payable
to any Bank, the Issuing Bank or the Administrative Agent, (i) the sum payable shall be increased
as may be necessary so that, after making all required deductions (including deductions applicable
to additional sums payable under this Section 2.12), such Bank, the Issuing Bank or the
Administrative Agent (as the case may be) receives an amount equal to the sum it would have
received had no such deductions been made; (ii) the Borrower shall make such deductions; and (iii)
the Borrower shall pay the full amount deducted to the relevant taxation authority or other
authority in accordance with applicable law. In addition, the Borrower agrees to pay any present
or future stamp or documentary taxes or any other excise or property taxes, charges or similar
levies which arise from any payment made or from the execution, delivery or registration of, or
otherwise with respect to, this Agreement, the Notes, or the other Credit Documents (hereinafter
referred to as “Other Taxes”).

          (b) Indemnification. The Borrower hereby indemnifies each Bank, the Issuing Bank
and the Administrative Agent for the full amount of Taxes or Other Taxes (including, without
limitation, any Taxes or Other Taxes imposed by any jurisdiction on amounts payable under this
Section 2.12) paid by such Bank, the Issuing Bank or the Administrative Agent, as the case may be,
and any liability arising therefrom or with respect thereto. Each payment required to be made by
the Borrower in respect of this indemnification shall be made to the Administrative Agent for the
benefit of any party claiming such indemnification within 30 days from the date the Borrower
receives written demand therefor from the Administrative Agent on behalf of itself as
Administrative Agent, the Issuing Bank or any such Bank.

          (c) Evidence of Tax Payments. Within 30 days after the date of any payment of Taxes
or Other Taxes, the Borrower will furnish to the Administrative Agent upon request thereby, at its
address referred to in Section 9.02, the original or a certified copy of a receipt evidencing
payment thereof. If no Taxes or Other Taxes are payable in respect of any payment hereunder, the
Borrower will furnish to the Administrative Agent, at such address, a certificate from each
appropriate taxing authority, or an opinion of counsel acceptable to the Administrative Agent, in
either case stating that such payment is exempt from or not subject to Taxes; provided,
however, that such certificate or opinion need only be given if (i) the Borrower makes any
payment from an account located outside the United States or (ii) the payment is made by a payor
that is not a United States Person. For purposes of this Section 2.12 the terms “United States”
and “United States Person” shall have the respective meanings set forth in Section 7701 of the
Code.

          (d) Survival. Without prejudice to the survival of any other agreement of the
Borrower hereunder, the agreements and obligations of the Borrower contained in this Section 2.12
shall survive the payment in full of principal and interest hereunder.

-34-

 

          (e) Foreign Bank Withholding Exemption. Each Bank and Issuing Bank that is not
incorporated under the laws of the United States of America or a state thereof agrees that it shall
deliver to the Borrower and the Administrative Agent on the date of this Agreement or upon, and as
a condition to, the effectiveness of any Assignment and Assumption (i) two duly completed copies of
United States Internal Revenue Service Form W-8BEN or W-8ECI or successor applicable form, as the
case may be, certifying in each case that such Bank is entitled to receive payments under this
Agreement and the Notes payable to it, without deduction or withholding of any United States
federal income taxes, (ii) if applicable, an Internal Revenue Service Form W-8 or W-9 or successor
applicable form, as the case may be, to establish an exemption from United States backup
withholding tax, and (iii) any other governmental forms which are necessary or required under an
applicable tax treaty or otherwise by law to reduce or eliminate any withholding tax, which have
been reasonably requested by the Borrower. Each Bank which delivers to the Borrower and the
Administrative Agent a Form W-8BEN or W-8ECI and Form W-8 or W-9 pursuant to the next preceding
sentence further undertakes to deliver to the Borrower and the Administrative Agent two further
copies of the said letter and Form W-8BEN or W-8ECI and Form W-8 or W-9, or successor applicable
forms, or other manner of certification, as the case may be, on or before the date that any such
letter or form expires or becomes obsolete or after the occurrence of any event requiring a change
in the most recent letter and form previously delivered by it to the Borrower and the
Administrative Agent, and such extensions or renewals thereof as may reasonably be requested by the
Borrower and the Administrative Agent certifying in the case of a Form W-8BEN or W-8ECI that such
Bank is entitled to receive payments under this Agreement without deduction or withholding of any
United States federal income taxes. If an event (including without limitation any change in
treaty, law or regulation) has occurred prior to the date on which any delivery required by the
preceding sentence would otherwise be required which renders all such forms inapplicable or which
would prevent any Bank from duly completing and delivering any such letter or form with respect to
it and such Bank advises the Borrower and the Administrative Agent that it is not capable of
receiving payments without any deduction or withholding of United States federal income tax, and in
the case of a Form W-8 or W-9, establishing an exemption from United States backup withholding tax,
such Bank shall not be required to deliver such letter or forms. The Borrower shall withhold tax
at the rate and in the manner required by the laws of the United States with respect to payments
made to a Bank failing to timely provide the requisite Internal Revenue Service forms.

          (f) Change of Applicable Lending Office. Any Bank claiming any additional amount
payable pursuant to this Section 2.12 shall use its reasonable best efforts (consistent with its
internal policy and applicable Governmental Rules) to change the jurisdiction of its lending office
if such a change would avoid the need for, or reduce the amount of, any such additional amount that
may thereafter accrue and would not, in the reasonable judgment of such Bank, be materially
disadvantageous to such Bank.

          (g) Repayment under Certain Circumstances. Each Bank (and the Administrative Agent
with respect to payments to the Administrative Agent for its own account) will (i) take all
reasonable actions by all usual means to maintain an exemption, if any, available to it from United
States tax withholding (whether available by treaty, by existing administrative waiver or by virtue
of the location of such Bank’s lending office) and (ii) otherwise cooperate with the Borrower to
minimize amounts payable by the Borrower under this Section 2.12;

-35-

 

provided, however, that neither any Bank nor the Administrative Agent shall be
obligated by reason of this Section 2.12(g) to contest the payment of any Taxes or Other Taxes, to
disclose any information regarding its tax affairs or tax computations or to reorder its tax or
other affairs. Subject to the foregoing, to the extent that the Borrower pays any amount pursuant
to this Section 2.12 and such Bank or the Administrative Agent receives a refund of any or all of
such amount, such refund shall be applied to reduce any amounts then due and owing under this
Agreement or, to the extent that no amounts are then due and owing under this Agreement, paid over
to the Borrower.

          (h) Exclusions. Notwithstanding anything contained herein to the contrary, the
Borrower shall not be required to make any payment to any Bank under this Section 2.12 with respect
to any Taxes or Other Taxes that (i) are attributable to such Bank’s failure to comply with the
requirements of this Section 2.12, (ii) are United States taxes imposed on amounts payable to such
Bank at the time the Bank became a party to this Agreement or (iii) are United States taxes imposed
as a result of an event occurring after the date on which such Bank became a Bank, other than a
change in any applicable Governmental Rule.

     Section 2.13. Letters of Credit.

          (a) Commitment.

               (i) The parties hereto acknowledge that on and after the Effective Date the Existing Letters
of Credit shall be Letters of Credit issued by the Issuing Bank pursuant to this Agreement. From
time to time from the Effective Date until the Termination Date, at the request of the Borrower,
the Issuing Bank shall, in reliance upon the agreements of the Banks set forth in this Section 2.13
on the terms and conditions hereinafter set forth, issue, increase, or extend the expiration date
of Letters of Credit for the account of the Borrower or any Subsidiary on any Business Day;
provided however, that for any Letter of Credit issued for the account of any
Subsidiary, the Borrower will be joint and severally liable for the reimbursement obligations of
such Subsidiary under such Letter of Credit as provided in subsection (h) below.

               (ii) No Letter of Credit shall be issued, increased, or extended:

                    (A) unless such issuance, increase, or extension would not cause the Letter of Credit Exposure
to exceed the aggregate Commitments less the aggregate outstanding principal amount of all
Advances;

                    (B) unless such Letter of Credit has an Expiration Date not later than the earlier of (a) 24
months after the date of issuance thereof and (b) March 31, 2011;

                    (C) unless such Letter of Credit Documents are in form and substance reasonably acceptable to
the Issuing Bank in its sole discretion;

                    (D) unless such Letter of Credit is either a Performance Letter of Credit or a Financial
Letter of Credit; and

                    (E) unless the Borrower has delivered to the Issuing Bank a completed and executed Letter of
Credit Application

-36-

 

               (iii) The Issuing Bank shall not be under any obligation to issue any Letter of Credit:

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

                    (B) if the issuance of such Letter of Credit would violate one or more policies of the Issuing
Bank; and

                    (C) if a default of any Bank’s obligations to fund under Section 2.13(c) exists or any
Bank is at such time a Default Lender hereunder, unless the Issuing Bank has entered into
satisfactory arrangements with the Borrower or such Bank to eliminate the Issuing Bank’s risk with
respect to such Bank.

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

               (i) Each Letter of Credit shall be issued or amended, as the case may be, upon the request of
the Borrower delivered to the Issuing Bank (with a copy to the Administrative Agent) in the form of
a Letter of Credit Application, appropriately completed and signed by a Responsible Officer of the
Borrower. Such Letter of Credit Application must be received by the Issuing Bank and the
Administrative Agent not later than 1:00 p.m. at least two Business Days (or such later date and
time as the Administrative Agent and the Issuing Bank may agree in a particular instance in their
sole discretion) prior to the proposed issuance date or date of amendment, as the case may be. In
the case of a request for an initial issuance of a Letter of Credit, such Letter of Credit
Application shall specify in form and detail satisfactory to the Issuing Bank: (A) the proposed
issuance date of the requested Letter of Credit (which shall be a Business Day); (B) the amount
thereof; (C) the expiry date thereof; (D) the name and address of the beneficiary thereof; (E) the
documents to be presented by such beneficiary in case of any drawing thereunder; (F) the full text
of any certificate to be presented by such beneficiary in case of any drawing thereunder; and (G)
such other matters as the Issuing Bank may reasonably require. In the case of a request for an
amendment of any outstanding Letter of Credit, such Letter of Credit Application shall specify in
form and detail satisfactory to the Issuing Bank (A) the Letter of Credit to be amended; (B) the
proposed date of amendment thereof (which shall be a Business Day); (C) the nature of the proposed
amendment; and (D) such other matters as the Issuing Bank may reasonably require. Additionally,
the Borrower shall furnish to the Issuing Bank and the Administrative Agent such other documents
and information pertaining to such

-37-

 

requested Letter of Credit issuance or amendment, including any Letter of Credit Documents, as
the Issuing Bank or the Administrative Agent may reasonably require.

               (ii) Promptly after receipt of any Letter of Credit Application, the Issuing Bank will confirm
with the Administrative Agent (by telephone or in writing) that the Administrative Agent has
received a copy of such Letter of Credit Application from the Borrower and, if not, the Issuing
Bank will provide the Administrative Agent with a copy thereof. Unless the Issuing Bank has
received written notice from any Bank, the Administrative Agent, or the Borrower, at least one
Business Day prior to the requested date of issuance or amendment of the applicable Letter of
Credit, that one or more applicable conditions contained in Article III shall not then be
satisfied, then, subject to the terms and conditions hereof, the Issuing Bank shall, on the
requested date, issue a Letter of Credit for the account of the Borrower (or the applicable
Subsidiary) or enter into the applicable amendment, as the case may be, in each case in accordance
with the Issuing Bank’s usual and customary business practices. Immediately upon the issuance of
each Letter of Credit, each Bank shall be deemed to, and hereby irrevocably and unconditionally
agrees to, purchase from the Issuing Bank a risk participation in such Letter of Credit in an
amount equal to the product of such Bank’s Pro Rata Share times the amount of such Letter of
Credit.

               (iii) If the Borrower so requests in any applicable Letter of Credit Application, the Issuing
Bank may, in its sole and absolute discretion, agree to issue a Letter of Credit that has automatic
extension provisions (each, an “Auto-Extension Letter of Credit”); provided that
any such Auto-Extension Letter of Credit must permit the Issuing Bank to prevent any such extension
at least once in each twelve-month period (commencing with the date of issuance of such Letter of
Credit) by giving prior notice to the beneficiary thereof not later than a day (the
“Non-Extension Notice Date”) in each such twelve-month period to be agreed upon at the time
such Letter of Credit is issued. Unless otherwise directed by the Issuing Bank, the Borrower shall
not be required to make a specific request to the Issuing Bank for any such extension. Once an
Auto-Extension Letter of Credit has been issued, the Banks shall be deemed to have authorized (but
may not require) the Issuing Bank to permit the extension of such Letter of Credit at any time to
an expiry date not later than March 31, 2011; provided, however, that the Issuing Bank shall not
permit any such extension if (A) the Issuing Bank has determined that it would not be permitted, or
would have no obligation, at such time to issue such Letter of Credit in its revised form (as
extended) under the terms hereof (by reason of the provisions of clause (ii) or (iii) of Section
2.13(a) or otherwise), or (B) it has received notice (which may be by telephone or in writing) on
or before the day that is five Business Days before the Non-Extension Notice Date (1) from the
Administrative Agent that the Majority Banks have elected not to permit such extension or (2) from
the Administrative Agent, any Bank or the Borrower that one or more of the applicable conditions
specified in Section 3.02 is not then satisfied, and in each such case directing the Issuing Bank
not to permit such extension.

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

-38-

 

               (v) All references in this Section 2.13 to times of day shall be references to (A) Eastern
time (daylight or standard, as applicable) if Bank of America is the applicable Issuing Bank or (B)
Pacific time (daylight or standard, as applicable) if UBOC is the applicable Issuing Bank.

          (c) Drawings and Reimbursements, Funding of Participations.

               (i) Upon receipt from the beneficiary of any Letter of Credit of any notice of a drawing under
such Letter of Credit, the Issuing Bank shall notify the Borrower and the Administrative Agent
thereof. Not later than 11:00 a.m. on the date of any payment by the Issuing Bank under a Letter of
Credit (each such date, an “Honor Date”), the Borrower shall reimburse the Issuing Bank
through the Administrative Agent in an amount equal to the amount of such drawing. If the Borrower
fails to so reimburse the Issuing Bank by such time, the Administrative Agent shall promptly notify
each Bank of the Honor Date, the amount of the unreimbursed drawing (the “Unreimbursed
Amount”), and the amount of such Bank’s Pro Rata Share thereof. In such event, the Borrower
shall be deemed to have requested a Borrowing of Reference Rate Advances to be disbursed on the
Honor Date in an amount equal to the Unreimbursed Amount, without regard to the minimum and
multiples specified in Section 2.01 for the principal amount of Reference Rate Advances, but
subject to the amount of the unutilized portion of the aggregate Commitments and the conditions set
forth in Section 3.02 (other than the delivery of a Notice of Borrowing). Any notice given by the
Issuing Bank or the Administrative Agent pursuant to this Section 2.13(c)(i) may be given by
telephone if immediately confirmed in writing; provided that the lack of such an immediate
confirmation shall not affect the conclusiveness or binding effect of such notice.

               (ii) Each Bank shall upon any notice pursuant to Section 2.13(c)(i) make funds available to
the Administrative Agent for the account of the Issuing Bank at the Administrative Agent’s Office
in an amount equal to its Pro Rata Share of the Unreimbursed Amount not later than 1:00 p.m. on the
Business Day specified in such notice by the Administrative Agent, whereupon, subject to the
provisions of Section 2.13(c)(iii), each Bank that so makes funds available shall be deemed to have
made a Reference Rate Advance to the Borrower in such amount. The Administrative Agent shall remit
the funds so received to the Issuing Bank.

               (iii) With respect to any Unreimbursed Amount that is not fully refinanced by a Borrowing of
Reference Rate Advances because the conditions set forth in Section 3.02 cannot be satisfied or for
any other reason, the Borrower shall be deemed to have incurred from the Issuing Bank an L/C
Borrowing in the amount of the Unreimbursed Amount that is not so refinanced, which L/C Borrowing
shall be due and payable on demand (together with interest) and shall bear interest at the Adjusted
Reference Rate in effect from time to time plus the Applicable Margin plus 2.00% per annum. In such
event, each Bank’s payment to the Administrative Agent for the account of the Issuing Bank pursuant
to Section 2.13(c)(ii) shall be deemed payment in respect of its participation in such L/C
Borrowing and shall constitute an L/C Advance from such Bank in satisfaction of its participation
obligation under this Section 2.13.

               (iv) Until each Bank funds its Advance or L/C Advance pursuant to this Section 2.13(c) to
reimburse the Issuing Bank for any amount drawn under any Letter of

-39-

 

Credit, interest in respect of such Bank’s Pro Rata Share of such amount shall be solely for
the account of the Issuing Bank.

               (v) Each Bank’s obligation to make Advances or L/C Advances to reimburse the Issuing Bank for
amounts drawn under Letters of Credit, as contemplated by this Section 2.13(c), shall be absolute
and unconditional and shall not be affected by any circumstance, including (A) any setoff,
counterclaim, recoupment, defense or other right which such Bank may have against the Issuing Bank,
the Borrower or any other Person for any reason whatsoever; (B) the occurrence or continuance of a
Default, or (C) any other occurrence, event or condition, whether or not similar to any of the
foregoing. No such making of an L/C Advance shall relieve or otherwise impair the obligation of
the Borrower to reimburse the Issuing Bank for the amount of any payment made by the Issuing Bank
under any Letter of Credit, together with interest as provided herein.

               (vi) If any Bank fails to make available to the Administrative Agent for the account of the
Issuing Bank any amount required to be paid by such Bank pursuant to the foregoing provisions of
this Section 2.13(c) by the time specified in Section 2.13(c)(ii), the Issuing Bank shall be
entitled to recover from such Bank (acting through the Administrative Agent), on demand, such
amount with interest thereon for the period from the date such payment is required to the date on
which such payment is immediately available to the Issuing Bank at a rate per annum equal to the
greater of the Federal Funds Rate and a rate determined by the Issuing Bank in accordance with
banking industry rules on interbank compensation. A certificate of the Issuing Bank submitted to
any Bank (through the Administrative Agent) with respect to any amounts owing under this clause
(vi) shall be conclusive absent manifest error.

          (d) Repayment of Participations.

               (i) At any time after the Issuing Bank has made a payment under any Letter of Credit and has
received from any Bank such Bank’s L/C Advance in respect of such payment in accordance with
Section 2.13(c), if the Administrative Agent receives for the account of the Issuing Bank any
payment in respect of the related Unreimbursed Amount or interest thereon (whether directly from
the Borrower or otherwise, including proceeds of Cash Collateral applied thereto by the
Administrative Agent), the Administrative Agent will distribute to such Bank its Pro Rata Share
thereof (appropriately adjusted, in the case of interest payments, to reflect the period of time
during which such Bank’s L/C Advance was outstanding) in the same funds as those received by the
Administrative Agent.

               (ii) If any payment received by the Administrative Agent for the account of the Issuing Bank
pursuant to Section 2.13(c)(i) is required to be returned under any of the circumstances described
in Section 9.10 (including pursuant to any settlement entered into by the Issuing Bank in its
discretion), each Bank shall pay to the Administrative Agent for the account of the Issuing Bank
its Pro Rata Share thereof on demand of the Administrative Agent, plus interest thereon from the
date of such demand to the date such amount is returned by such Bank, at a rate per annum equal to
the Federal Funds Rate from time to time in effect. The obligations of the Banks under this clause
shall survive the payment in full of the Obligations and the termination of this Agreement.

-40-

 

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

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

               (ii) the existence of any claim, counterclaim, setoff, defense or other right that the
Borrower or any Subsidiary may have at any time against any beneficiary or any transferee of such
Letter of Credit (or any Person for whom any such beneficiary or any such transferee may be
acting), the Issuing Bank or any other Person, whether in connection with this Agreement, the
transactions contemplated hereby or by such Letter of Credit or any agreement or instrument
relating thereto, or any unrelated transaction;

               (iii) any draft, demand, certificate or other document presented under such Letter of Credit
proving to be forged, fraudulent, invalid or insufficient in any respect or any statement therein
being untrue or inaccurate in any respect; or any loss or delay in the transmission or otherwise of
any document required in order to make a drawing under such Letter of Credit;

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

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

     The Borrower shall promptly examine a copy of each Letter of Credit and each amendment thereto
that is delivered to it and, in the event of any claim of noncompliance with the Borrower’s
instructions or other irregularity, the Borrower will immediately notify the Issuing Bank. To the
extent permitted by applicable law, the Borrower shall be conclusively deemed to have waived any
such claim against the Issuing Bank and its correspondents unless such notice is given as
aforesaid.

          (f) Role of Issuing Bank. Each Bank and the Borrower agree that, in paying any
drawing under a Letter of Credit, the Issuing Bank shall not have any responsibility to obtain any
document (other than any sight draft, certificates and documents expressly required by the Letter
of Credit) or to ascertain or inquire as to the validity or accuracy of any such document or the
authority of the Person executing or delivering any such document. None of the Issuing Bank, the
Administrative Agent, any of their respective Related Parties nor any correspondent, participant or
assignee of the Issuing Bank shall be liable to any Bank for (i) any action taken or

-41-

 

omitted in connection herewith at the request or with the approval of the Banks or the
Majority Banks, as applicable; (ii) any action taken or omitted in the absence of gross negligence
or willful misconduct; or (iii) the due execution, effectiveness, validity or enforceability of any
document or instrument related to any Letter of Credit or Letter of Credit Document. The Borrower
hereby assumes all risks of the acts or omissions of any beneficiary or transferee with respect to
its use of any Letter of Credit; provided, however, that this assumption is not intended to, and
shall not, preclude the Borrower’s pursuing such rights and remedies as it may have against the
beneficiary or transferee at law or under any other agreement. None of the Issuing Bank, the
Administrative Agent, any of their respective Related Parties nor any correspondent, participant or
assignee of the Issuing Bank shall be liable or responsible for any of the matters described in
clauses (i) through (v) of Section 2.13(e); provided, however, that anything in
such clauses to the contrary notwithstanding, the Borrower may have a claim against the Issuing
Bank, and the Issuing Bank may be liable to the Borrower, to the extent, but only to the extent, of
any direct, as opposed to consequential or exemplary, damages suffered by the Borrower directly, or
indirectly by a Subsidiary, which the Borrower proves were caused by the Issuing Bank’s willful
misconduct or gross negligence or the Issuing Bank’s willful failure to pay under any Letter of
Credit after the presentation to it by the beneficiary of a sight draft and certificate(s) strictly
complying with the terms and conditions of a Letter of Credit. In furtherance and not in
limitation of the foregoing, the Issuing Bank may accept documents that appear on their face to be
in order, without responsibility for further investigation, regardless of any notice or information
to the contrary, and the Issuing Bank shall not be responsible for the validity or sufficiency of
any instrument transferring or assigning or purporting to transfer or assign a Letter of Credit or
the rights or benefits thereunder or proceeds thereof, in whole or in part, which may prove to be
invalid or ineffective for any reason.

          (g) Cash Collateral. Upon the request of the Administrative Agent, if, as of 5 days
prior to the Termination Date, any Letter of Credit Obligation for any reason remains outstanding,
the Borrower shall, in each case, immediately Cash Collateralize the then outstanding amount of all
Letter of Credit Obligations. Sections 2.04(b), 7.02 and 7.03 set forth certain additional
requirements to deliver Cash Collateral hereunder. For purposes of this Section 2.13, Sections
2.04, 7.02 and 7.03, “Cash Collateralize” means to pledge and deposit with or deliver to
the Administrative Agent, for the benefit of the Issuing Bank and the Banks, as collateral for the
Letter of Credit Obligations, cash or deposit account balances pursuant to documentation in form
and substance satisfactory to the Administrative Agent and the Issuing Bank (which documents are
hereby consented to by the Banks). Derivatives of such term have corresponding meanings. The
Borrower hereby grants to the Administrative Agent, for the benefit of the Issuing Bank and the
Banks, a security interest in all such cash, deposit accounts and all balances therein and all
proceeds of the foregoing. Cash Collateral shall be maintained in blocked, non-interest bearing
deposit accounts at Bank of America. Notwithstanding anything herein to the contrary, provided
that the Borrower has Cash Collateralized the then outstanding amount of all Letter of Credit
Obligations with respect to each Letter of Credit with an expiration date after the Termination
Date in accordance with this Section 2.15(g), each Bank’s participation in the Letter of Credit
Obligations shall be released as of the Termination Date.

          (h) Applicability of ISP and UCP. Unless otherwise expressly agreed by the Issuing
Bank and the Borrower when a Letter of Credit is issued (including any such agreement applicable to
an Existing Letter of Credit), (i) the rules of the ISP shall apply to each standby

-42-

 

Letter of Credit, and (ii) the rules of the Uniform Customs and Practice for Documentary
Credits, as most recently published by the International Chamber of Commerce at the time of
issuance shall apply to each commercial Letter of Credit.

          (i) Conflict with Letter of Credit Documents. In the event of any conflict between
the terms hereof and the terms of any Letter of Credit Document, the terms hereof shall control.

          (j) Letters of Credit Issued for Subsidiaries. Notwithstanding that a Letter of
Credit issued or outstanding hereunder is in support of any obligations of, or is for the account
of, a Subsidiary, the Borrower shall be obligated to reimburse the Issuing Bank hereunder for any
and all drawings under such Letter of Credit. The Borrower hereby acknowledges that the issuance
of Letters of Credit for the account of Subsidiaries inures to the benefit of the Borrower, and
that the Borrower’s business derives substantial benefits from the businesses of such Subsidiaries.

     Section 2.14. Replacement of Banks. If any Bank requests compensation under Section
2.11, or if the Borrower is required to pay any additional amount to any Bank or any Governmental
Person for the account of any Bank pursuant to Section 2.12, or if any Bank is a Defaulting Bank or
a Non-Consenting Bank (as defined below in this Section 2.14), then the Borrower may, at its sole
expense and effort, upon notice to such Bank and the Administrative Agent, require such Bank to
assign and delegate, without recourse (in accordance with and subject to the restrictions contained
in, and consents required by, Section 9.06), all of its interests, rights and obligations under
this Agreement and the related Credit Documents to an assignee that shall assume such obligations
(which assignee may be another Bank, if a Bank accepts such assignment), provided that:

          (a) the Assignee shall have paid to the Administrative Agent the assignment fee specified in
Section 9.06(a);

          (b) such Bank shall have received payment of an amount equal to the outstanding principal of
its Advances and L/C Advances, accrued interest thereon, accrued fees and all other amounts payable
to it hereunder and under the other Credit Documents (including any amounts under Section 2.11 and
2.12) from the assignee (to the extent of such outstanding principal and accrued interest and fees)
or the Borrower (in the case of all other amounts);

          (c) in the case of any such assignment resulting from a claim for compensation under Section
2.11 or payments required to be made pursuant to Section 2.12, such assignment will result in a
reduction in such compensation or payments thereafter; and

          (d) such assignment does not conflict with applicable Governmental Rules.

     A Bank shall not be required to make any such assignment or delegation if, prior thereto, as a
result of a waiver by such Bank or otherwise, the circumstances entitling the Borrower to require
such assignment and delegation cease to apply. In the event that (i) the Borrower or the
Administrative Agent requests that the Banks consent to a waiver of any provision of the Credit
Documents or agree to any amendment thereto, (ii) such consent or amendment requires the agreement
of all of the Banks in accordance with the terms of Section 9.01 and (iii) at least the

-43-

 

Majority Banks have agreed to such consent or amendment, then any Bank that does not agree to
such consent or amendment shall be a “Non-Consenting Bank”.

     Section 2.15. Increase in Commitments.

          (a) Request for Increase. Provided there exists no Default, upon notice to the
Administrative Agent (which shall promptly notify the Banks), the Borrower may from time to time,
request an increase in the aggregate Commitments by an amount (for all such requests) not exceeding
$100,000,000; provided that (i) any such request for an increase shall be in a minimum amount of
$20,000,000, and (ii) the Borrower may make a maximum of five such requests. At the time of
sending such notice, the Borrower (in consultation with the Administrative Agent) shall specify the
time period within which each Bank is requested to respond (which shall in no event be less than
ten Business Days from the date of delivery of such notice to the Banks).

          (b) Bank Elections to Increase. Each Bank shall notify the Administrative Agent
within such time period whether or not it agrees to increase its Commitment and, if so, whether by
an amount equal to, greater than, or less than its Pro Rata Share of such requested increase. Any

be required to pay or discharge any such tax, assessment, charge, levy or claim that is being
contested in good faith and, in the case of any such tax, assessment, charge or levy, by proper
proceedings and as to which, in all such cases, it is maintaining appropriate reserves in

otherwise permitted under the Credit Documents with any of its Affiliates (other than the Borrower

     Section 5.12. Environmental Remediation and Indemnification. If at any time any
Hazardous Material is discovered on, under or about any Mortgaged Property or any other property
owned or operated by the Borrower or any Subsidiary (“Other Property”) and failure to
remediate the same would cause the Borrower or any Subsidiary to be in violation of any
Environmental Law that would reasonably be expected to have a Material Adverse Effect, the Borrower
will inform the Administrative Agent of the same and of the Borrower’s proposed remediation
program, and the Borrower or such Subsidiary will, at no cost and expense to the Collateral Agent,
the Administrative Agent or the Banks, and only to the extent of any legal requirement under
applicable Environmental Laws for the Borrower or such Subsidiary to do so, remediate or remove
such Hazardous Materials from such Mortgaged Property or Other Property

such remediation program as a prudent operator would undertake, (b) the approval of the appropriate
Governmental Persons, if any such approval is required under the applicable Environmental Laws, and

have a Material Adverse Effect. The Borrower and any Subsidiary shall have the right to contest
any notice or directive by any appropriate Governmental Person to remediate or remove Hazardous
Materials from any Mortgaged Property or Other Property so long as the Borrower or such Subsidiary
diligently prosecutes such contest to completion and complies with any final order or
determination. The Borrower shall be solely responsible for, and will indemnify and hold harmless
the Collateral Agent, the Administrative Agent, the Bookrunner, the Lead Arranger, the Syndication
Agent, any Co-Documentation Agent and the Banks and their respective directors, officers,
employees, agents, successors and assigns from and against, any and all losses, damages, demands,
claims, causes of action, judgments, actions, assessments, penalties, costs, expenses and
liabilities to the extent that they directly or indirectly arise out of or are attributable to the
release of any Hazardous Materials at any Mortgaged Property or Other Property, including the
following: (i) all foreseeable and unforeseeable consequential damages; (ii) the costs of any
repair, cleanup or detoxification of any Mortgaged Property or Other Property required by any
applicable Environmental Laws, and the preparation and implementation of any closure, remedial or
other plans required by any applicable Environmental Laws; and (iii) all reasonable costs and
expenses incurred by the Collateral Agent, the Administrative Agent or any Bank in connection with
clauses (i) and (ii) above, including reasonable attorneys’ fees; provided,
however, that the Borrower shall not be liable for any of the foregoing if a final,
nonappealable judgment by a court of competent jurisdiction finds that such release of Hazardous
Materials resulted from the gross negligence or willful misconduct of the Collateral Agent, the
Administrative Agent or a Bank. The indemnities provided in this section shall survive the
repayment or any other satisfaction of the Obligations of the Borrower under the Credit Documents.

     Section 5.13. Use of Proceeds. The proceeds of Advances will be used by the Borrower
(a) to refinance existing Debt to the extent not prohibited hereunder, (b) for capital
expenditures, (c) for working capital, including the issuance of Letters of Credit, (d) for
Acquisitions, (e) to fund Quarterly Distributions to the extent permitted by Section 6.06, (f) to
pay fees, costs and expenses owed pursuant to this Agreement and (f) for other general partnership
purposes. The Borrower is not engaged in the business of extending credit for the purpose of
purchasing or carrying margin stock (within the meaning of Regulation U). No proceeds of the
Borrowings will be used to purchase or carry any margin stock in violation of Regulations T, U or
X.

     Section 5.14. Clean Down Period. During each calendar year during the term of this
Agreement, there shall be a period of fifteen (15) consecutive days (the “Clean Down
Period”) during which (a) there are no Distribution Loans outstanding and (b) no Distributions
Loans will be made.

     Section 5.15. Post-Closing Requirements. Within 120 days following the Effective Date
(or such later date as is acceptable to the Administrative Agent), the Borrower shall deliver to
the Administrative Agent, in form and substance satisfactory to Administrative Agent, a copy of the
signed order of the Louisiana Public Service Commission authorizing each of the Louisiana
Guarantors to execute Guaranties and Security Documents with respect to the Obligations under

-57-

 

this Agreement (the “Louisiana Public Service Commission Order”). Notwithstanding
anything herein to the contrary, within the 120 day period following the Effective Date (or such
later date as is acceptable to the Administrative Agent), the failure to have obtained the
Louisiana Public Service Commission Order shall not be considered to be a violation of the
representations, warranties and covenants in this Agreement or any of the other Loan Documents so
long as the Borrower is diligently pursuing the same.

ARTICLE VII

REMEDIES

     Section 7.01. Events of Default. The occurrence of any of the following events shall
constitute an “Event of Default” under any Credit Document:

          (a) Payment. The Borrower shall fail to (i) pay any principal of any Advance or any
L/C Borrowing when the same becomes due and payable, (ii) pay any interest on any Note or any fee
owing in connection with the Obligations, this Agreement or any of the other Credit Documents
within three Business Days after the same becomes due and payable or (iii) pay any other amount
owing in connection with the Obligations, this Agreement or any of the other Credit Documents
within five Business Days after the same becomes due and payable;

          (b) Representation and Warranties. Any representation or warranty made or deemed to

          (c) Covenant Breaches. The Borrower fails to perform or observe any term, covenant or
agreement contained in Sections 5.02, 5.13 or Article VI of this Agreement; or the Borrower, any
Guarantor or any Subsidiary fails to perform or observe any other term, covenant or agreement
contained in any Credit Document on its part to be performed or observed, and such failure remains

outstanding in a principal amount of at least $10,000,000 in the aggregate, or any interest or
premium thereon, when the same becomes due and payable (whether by scheduled maturity, required
prepayment, acceleration demand or otherwise), and such failure continues after the applicable
grace period, if any, specified in the agreement or instrument relating to such Debt; any other
event occurs or condition exists under any agreement or instrument relating to any such Debt and
continues after the applicable grace period, if any, specified in such agreement or instrument, if
the effect of such event or condition is to accelerate, or to permit the acceleration of, the
maturity of such Debt; or any such Debt is declared to be due and payable or is required to be
prepaid, redeemed, purchased or defeased (other than by a regularly scheduled required prepayment,
redemption, purchase or defeasance), or an offer to prepay, redeem, purchase or defease such Debt
is required to be made, in each case before the stated maturity thereof;

          (e) Insolvency. The Borrower or any Material Subsidiary generally does not pay its
debts as such debts become due, admits in writing its inability to pay its debts generally or makes
a general assignment for the benefit of creditors; any proceeding is instituted by the Borrower or
any Material Subsidiary seeking to adjudicate it a bankrupt or insolvent, seeking liquidation,
winding up, reorganization, arrangement, adjustment, protection, relief, or composition of it or
its debts under any law relating to bankruptcy, insolvency or reorganization or relief of debtors,
or seeking the entry of an order for relief or the appointment of a receiver,

proceeding is instituted against the Borrower or any Material Subsidiary seeking to adjudicate it a
bankrupt or insolvent, seeking liquidation, winding up, reorganization, arrangement, adjustment,

of its property, and either such proceeding remains undismissed or unstayed for a period of 60 days
or any of the actions sought in such proceeding (including the entry of an order for relief against
the Borrower or such Material Subsidiary, as applicable, or the appointment of a receiver, trustee,
custodian or other similar official for it or for any substantial part of its property) occurs; or
the Borrower or any Material Subsidiary takes any action to authorize any of the actions set forth
above in this Section 7.01(e);

          (f) Judgments.

               (i) Any judgment or order for the payment of money in excess of $10,000,000 is rendered
against the Borrower or any Material Subsidiary by a court of competent jurisdiction, and either
(a) enforcement proceedings are commenced by any creditor upon such judgment or order or (b) there
is any period of 30 consecutive days during which a stay of enforcement of such judgment or order,
by reason of a pending appeal or otherwise, is not in effect, unless such judgment or order has
been vacated, satisfied, dismissed, or bonded pending appeal or, in the case of a judgment or order
the entire amount of which is covered by insurance (subject to applicable deductibles), is the
subject of a binding agreement with the plaintiff and the insurer covering payment therefor; or

               (ii) any nonmonetary judgment or order is rendered against the Borrower or any Material
Subsidiary that could reasonably be expected to have a Material Adverse Effect, and there is any
period of 30 consecutive days during which a stay of enforcement of such judgment or order, by
reason of a pending appeal or otherwise, is not in effect;

          (g) [Intentionally deleted];

          (h) Credit Documents. Any material provision of any Credit Document for any reason
ceases to be valid and binding on, or enforceable against, the Borrower or any Material Subsidiary,
as applicable (except (i) pursuant to the terms of such Credit Document, (ii) as permitted by this
Agreement (including, without limitation, Sections 6.04 and 9.18 hereof or (iii) to the extent such
provision is released in writing by the Administrative Agent), or the Borrower or any Material
Subsidiary, as applicable, so states in writing;

          (i) Security Documents. Any Security Document for any reason (except pursuant to the
terms hereof (including, without limitation, Sections 6.04 and 9.18 hereof) or thereof) ceases to
create an Acceptable Security Interest on any material portion of the Collateral purported to be
covered by such Security Document, and the same, if curable, is not cured within 15 days after the
Administrative Agent notifies the Borrower or the affected Subsidiary, as applicable, of the same;
or

-67-

 

          (j) Change of Control. A Change of Control shall occur.

     Section 7.02. Optional Acceleration of Maturity. If any Event of Default (other than
an Event of Default pursuant to paragraph (e) of Section 7.01 with respect to the Borrower) shall
have occurred and be continuing, then, and in any such event,

          (a) the Administrative Agent (i) shall at the request, or may with the consent, of the
Majority Banks, by notice to the Borrower, declare the obligation of each Bank and the Issuing Bank
to make extensions of credit hereunder, including the making of Advances and issuing of Letters of
Credit, to be terminated, whereupon the same shall forthwith terminate or (ii) shall, at the
request, or may with the consent, of the Majority Banks, by notice to the Borrower, declare all
principal, interest, fees, reimbursements, indemnifications and all other amounts payable under
this Agreement to be forthwith due and payable, whereupon the Notes (if any), all such principal,
interest, and other amounts shall become and be forthwith due and payable in full, without
presentment, demand, protest or further notice of any kind (including, without limitation, any
notice of intent to accelerate or notice of acceleration), all of which are hereby expressly waived
by the Borrower;

          (b) the Borrower shall, on demand of the Administrative Agent at the request or with the
consent of the Majority Banks, deposit with the Administrative Agent Cash Collateral in an amount
of cash equal to the Letter of Credit Exposure as security for the Obligations; and

          (c) the Administrative Agent shall at the request or may with the consent of the Majority
Banks proceed to enforce its rights and remedies under the Security Documents, the Guaranties, and
any other Credit Documents for the ratable benefit of the Creditors (as defined in the
Intercreditor Agreement) by appropriate proceedings.

     Section 7.03. Automatic Acceleration of Maturity. If any Event of Default pursuant to
paragraph (e) of Section 7.01 shall occur with respect to the Borrower,

          (a) (i) the obligation of each Bank and the Issuing Bank to make extensions of credit
hereunder, including making Advances and issuing Letters of Credit, shall immediately and
automatically be terminated and (ii) all principal, interest, fees, reimbursements,

of intent to accelerate or notice of acceleration), all of which are hereby expressly waived by the
Borrower; and

any other Credit Document for the ratable benefit of the Creditors by appropriate proceedings.

-68-

 

     Section 7.04. Non-exclusivity of Remedies. No remedy conferred upon the
Administrative Agent or any Bank is intended to be exclusive of any other remedy, and each remedy
shall be cumulative of all other remedies existing by contract, at law, in equity, by statute or
otherwise.

     Section 7.05. Right of Set-off. Upon the occurrence and during the continuance of any
Event of Default, the Administrative Agent and each Bank is hereby authorized at any time and from
time-to-time, to the fullest extent permitted by law, to set off and apply any and all deposits
(general or special, time or demand, provisional or final) at any time held and other indebtedness
at any time owing by the Administrative Agent or any such Bank to or for the credit or the account
of the Borrower against any and all of the obligations of the Borrower now or hereafter existing
under this Agreement, any Notes held by such Bank, and the other Credit Documents, irrespective of
whether or not the Administrative Agent or such Bank shall have made any demand under this
Agreement, any Note, or such other Credit Documents, and although such obligations may be
unmatured. The Administrative Agent and each Bank agrees to promptly notify the Borrower after any
such set-off and application made by the Administrative Agent or such Bank, provided that the
failure to give the notice shall not affect the validity of such set-off and application. The
rights of the Administrative Agent and the Banks under this Section are in addition to any other
rights and remedies (including, without limitation, other rights of set-off) which the
Administrative Agent or the Banks may have.

     Section 7.06. Application of Collateral. The proceeds of any sale, or other
realization upon all or any part of the Collateral (as defined in each of the Security Documents)
shall be applied by the Administrative Agent in accordance with the terms of the Intercreditor
Agreement; provided, however that if the Intercreditor Agreement has been terminated, the
Administrative Agent shall apply such proceeds in the following order:

     first, to payment of the reasonable expenses of sale or other realization of such
Collateral, including reasonable compensation to the Administrative Agent and its agents and
counsel;

     second, to the payment of all reasonable expenses, liabilities, and advances incurred
or made by the Administrative Agent in connection therewith, and to the ratable payment of any
other unreimbursed reasonable expenses for which the Administrative Agent or any Bank is to be
reimbursed pursuant to the terms hereof or any other Credit Document;

     third, to the ratable payment of accrued but unpaid agent’s fees, commitment fees,

the Banks in respect of the Advances and Letters of Credit under this Agreement and the Notes;

     fourth, to the ratable payment of accrued but unpaid interest on the Advances owing
under this Agreement; and

     fifth, to the ratable payment of all other Obligations which relate to the Advances,
Letters of Credit, any Interest Rate Contract between the Borrower or any Subsidiary and a Bank or

a Bank or an Affiliate thereof and which are owing to the Administrative Agent, the Collateral
Agent, the Banks and their Affiliates.

-69-

 

     Any surplus of such cash or cash proceeds held by the Administrative Agent and remaining after
the payment in full of all the Obligations shall be promptly paid over to the Borrower or to

ARTICLE VIII

THE ADMINISTRATIVE AGENT AND THE COLLATERAL AGENT

     Section 8.01. Appointment and Authority. Each of the Banks and the Issuing Bank
hereby irrevocably appoints Bank of America to act on its behalf as the Administrative Agent and
Collateral Agent hereunder and under the other Credit Documents and authorizes the Agents to take
such actions on its behalf and to exercise such powers as are delegated to the Agents by the terms
hereof or thereof, together with such actions and powers as are reasonably incidental thereto. The
provisions of this Article are solely for the benefit of the Agents, the Banks and the Issuing
Bank, and neither the Borrower nor any other Guarantor shall have rights as a third party
beneficiary of any of such provisions.

     Section 8.02. Rights as a Bank. The Person serving as the Agents hereunder shall have
the same rights and powers in its capacity as a Bank as any other Bank and may exercise the same as
though it were not an Agent and the term “Bank” or “Banks” shall, unless otherwise expressly
indicated or unless the context otherwise requires, include the Person serving as the Agents
hereunder in its individual capacity. Such Person and its Affiliates may accept deposits from,
lend money to, act as the financial advisor or in any other advisory capacity for and generally
engage in any kind of business with the Borrower or any Subsidiary or other Affiliate thereof as if
such Person were not an Agent hereunder and without any duty to account therefor to the Banks.

     Section 8.03. Exculpatory Provisions. The Agents shall not have any duties or
obligations except those expressly set forth herein and in the other Credit Documents. Without
limiting the generality of the foregoing, the Agents:

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

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

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

-70-

 

     The Agents shall not be liable for any action taken or not taken by it (i) with the consent or
at the request of the Majority Banks (or such other number or percentage of the Banks as shall be
necessary, or as the Agent shall believe in good faith shall be necessary, under the circumstances
as provided in Sections 9.01 and 7.02) or (ii) in the absence of its own gross negligence or
willful misconduct. The Agents shall be deemed not to have knowledge of any Default unless and
until notice describing such Default is given to the Agent by the Borrower, a Bank or the Issuing
Bank.

     The Agents shall not be responsible for or have any duty to ascertain or inquire into (i) any
statement, warranty or representation made in or in connection with this Agreement or any other
Credit Document, (ii) the contents of any certificate, report or other document delivered hereunder
or thereunder or in connection herewith or therewith, (iii) the performance or observance of any of
the covenants, agreements or other terms or conditions set forth herein or therein or the
occurrence of any Default, (iv) the validity, enforceability, effectiveness or genuineness of this
Agreement, any other Credit Document or any other agreement, instrument or document or (v) the
satisfaction of any condition set forth in Article III or elsewhere herein, other than to confirm
receipt of items expressly required to be delivered to the Agent.

     Section 8.04. Reliance by Agents. The Agents shall be entitled to rely upon, and
shall not incur any liability for relying upon, any notice, request, certificate, consent,
statement, instrument, document or other writing (including any electronic message, Internet or
intranet website posting or other distribution) believed by it to be genuine and to have been
signed, sent or otherwise authenticated by the proper Person. The Agents also may rely upon any
statement made to it orally or by telephone and believed by it to have been made by the proper
Person, and shall not incur any liability for relying thereon. In determining compliance with any
condition hereunder to the making of an Advance, or the issuance of a Letter of Credit, that by its
terms must be fulfilled to the satisfaction of a Bank or the Issuing Bank, the Agents may presume
that such condition is satisfactory to such Bank or the Issuing Bank unless the Agent shall have
received notice to the contrary from such Bank or the Issuing Bank prior to the making of such
Advance or the issuance of such Letter of Credit. The Agents 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.

     Section 8.05. Delegation of Duties. The Agents may perform any and all of its duties
and exercise its rights and powers hereunder or under any other Credit Document by or through any
one or more sub-agents appointed by the Agent. The Agents and any such sub-agent may perform any
and all of its duties and exercise its rights and powers by or through their respective Related
Parties. The exculpatory provisions of this Article shall apply to any such sub-agent and to the
Related Parties of the Agents and any such sub-agent, and shall apply to their respective
activities in connection with the syndication of the credit facilities provided for herein as well
as activities as Agent.

     Section 8.06. Resignation of Administrative Agent. The Administrative Agent may at
any time give notice of its resignation to the Banks, the Issuing Bank and the Borrower. Upon
receipt of any such notice of resignation, the Majority Banks shall have the right, in consultation
with the Borrower, to appoint a successor, which shall be a bank with an office in the United

-71-

 

States, or an Affiliate of any such bank with an office in the United States. If no such
successor shall have been so appointed by the Majority Banks and shall have accepted such
appointment within 30 days after the retiring Administrative Agent gives notice of its resignation,
then the retiring Administrative Agent may on behalf of the Banks and the Issuing Bank, appoint a
successor Administrative Agent meeting the qualifications set forth above; provided that if the
Administrative Agent shall notify the Borrower and the Banks that no qualifying Person has accepted
such appointment, then such resignation shall nonetheless become effective in accordance with such
notice and (a) the retiring Administrative Agent shall be discharged from its duties and
obligations hereunder and under the other Credit Documents (except that in the case of any
collateral security held by the Administrative Agent on behalf of the Banks or the Issuing Bank
under any of the Credit Documents, the retiring Administrative Agent shall continue to hold such
collateral security until such time as a successor Administrative Agent is appointed) and (b) all
payments, communications and determinations provided to be made by, to or through the
Administrative Agent shall instead be made by or to each Bank and the Issuing Bank directly, until
such time as the Majority Banks appoint a successor Administrative Agent as provided for above in
this Section. Upon the acceptance of a successor’s appointment as Administrative Agent hereunder,
such successor shall succeed to and become vested with all of the rights, powers, privileges and
duties of the retiring (or retired) Administrative Agent, and the retiring Administrative Agent
shall be discharged from all of its duties and obligations hereunder or under the other Credit
Documents (if not already discharged therefrom as provided above in this Section). 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
retiring Administrative Agent’s resignation hereunder and under the other Credit Documents, the
provisions of this Article and Section 9.04 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 the retiring Administrative Agent was
acting as Administrative Agent.

     Any resignation by Bank of America as Administrative Agent pursuant to this Section shall also
constitute its resignation as Issuing Bank and Collateral Agent. Upon the acceptance of a
successor’s appointment as Administrative Agent hereunder, (a) such successor shall succeed to and
become vested with all of the rights, powers, privileges and duties of the retiring Issuing Bank
and Collateral Agent, (b) the retiring Issuing Bank and Collateral Agent shall be discharged from
all of their respective duties and obligations hereunder or under the other Credit Documents, and
(c) the successor Issuing Bank shall issue letters of credit in substitution for the Letters of
Credit, if any, outstanding at the time of such succession or make other arrangement satisfactory
to the retiring Issuing Bank to effectively assume the obligations of the retiring Issuing Bank
with respect to such Letters of Credit.

     Section 8.07. Non-Reliance on Agents and Other Banks. Each Bank and the Issuing Bank
acknowledges that it has, independently and without reliance upon the Agents or any other Bank or
any of their Related Parties and based on such documents and information as it has deemed
appropriate, made its own credit analysis and decision to enter into this Agreement. Each Bank and
the Issuing Bank also acknowledges that it will, independently and without reliance upon the Agents
or any other Bank or any of their Related Parties and based on such documents and information as it
shall from time to time deem appropriate, continue to make its

-72-

 

own decisions in taking or not taking action under or based upon this Agreement, any other
Credit Document or any related agreement or any document furnished hereunder or thereunder.

     Section 8.08. No Other Duties, Etc. Anything herein to the contrary notwithstanding,
none of the Bookrunner, Lead Arranger, Syndication Agent or any Co-Documentation Agent listed on
the cover page hereof shall have any powers, duties or responsibilities under this Agreement or any
of the other Credit Documents, except in its capacity, as applicable, as an Agent, a Bank or the
Issuing Bank hereunder.

     Section 8.09. Administrative Agent May File Proofs of Claim. In case of the pendency
of any receivership, insolvency, liquidation, bankruptcy, reorganization, arrangement, adjustment,
composition or other judicial proceeding relative to the Borrower or any Guarantor, the
Administrative Agent (irrespective of whether the principal of any Advance or Letter of Credit
Obligation shall then be due and payable as herein expressed or by declaration or otherwise and
irrespective of whether the Administrative Agent shall have made any demand on the Borrower) shall
be entitled and empowered, by intervention in such proceeding or otherwise

          (a) to file and prove a claim for the whole amount of the principal and interest owing and
unpaid in respect of the Advances, Letter of Credit Obligations and all other Obligations that are
owing and unpaid and to file such other documents as may be necessary or advisable in order to have
the claims of the Banks, the Issuing Bank and the Administrative Agent (including any claim for the
reasonable compensation, expenses, disbursements and advances of the Banks, the Issuing Bank and
the Administrative Agent and their respective agents and counsel and all other amounts due the
Banks, the Issuing Bank and the Administrative Agent under Sections 2.13, 2.06 and 9.04) allowed in
such judicial proceeding; and

          (b) to collect and receive any monies or other property payable or deliverable on any such
claims and to distribute the same;

and any custodian, receiver, assignee, trustee, liquidator, sequestrator or other similar official
in any such judicial proceeding is hereby authorized by each Bank and the Issuing Bank to make such
payments to the Administrative Agent and, in the event that the Administrative Agent shall consent
to the making of such payments directly to the Banks and the Issuing Bank, to pay to the
Administrative Agent any amount due for the reasonable compensation, expenses, disbursements and
advances of the Administrative Agent and its agents and counsel, and any other amounts due the
Administrative Agent under Sections 2.06 and 9.04.

     Nothing contained herein shall be deemed to authorize the Administrative Agent to authorize or
consent to or accept or adopt on behalf of any Bank or the Issuing Bank any plan of reorganization,
arrangement, adjustment or composition affecting the Obligations or the rights of any Bank or to
authorize the Administrative Agent to vote in respect of the claim of any Bank in any such
proceeding.

     Section 8.10. Collateral and Guaranty Matters. The Banks and the Issuing Bank
irrevocably authorize the Collateral Agent, at its option and in its discretion,

          (a) to release any Lien on any property granted to or held by the Collateral Agent under any
Credit Document (i) upon termination of the aggregate Commitments and

-73-

 

payment in full of all Obligations (other than contingent indemnification obligations) and the
expiration, termination or Cash Collateralization of all Letters of Credit, (ii) that is sold or to
be sold as part of or in connection with any sale permitted hereunder or under any other Credit
Document, (iii) pursuant to Section 9.18 or (iv) subject to Section 9.01, if approved, authorized
or ratified in writing by the Majority Banks;

          (b) to subordinate any Lien on any property granted to or held by the Administrative Agent
under any Credit Document to the holder of any Lien on such property that is permitted by Section
6.01; and

          (c) to release any Guarantor from its obligations under the Guaranty and any other applicable
Credit Document if such Person ceases to be a Subsidiary as a result of a transaction permitted
hereunder.

     Upon request by the Administrative Agent at any time, the Majority Banks will confirm in
writing the Administrative Agent’s authority to release or subordinate its interest in particular
types or items of property, or to release any Guarantor from its obligations under the Guaranty or
any other Credit Document pursuant to this Section 8.10.

     Section 8.11. Swap Agreements. The benefit of the Security Documents and of the
provisions of this Agreement relating to any collateral securing the Obligations shall also extend
to and be available to those Banks or their Affiliates which are counterparties to any Interest
Rate Contract or Hydrocarbon Hedge Agreement with the Borrower or any of its Subsidiaries on a pro
rata basis in respect of any obligations of the Borrower or any of its Subsidiaries which arise
under any such Interest Rate Contract or Hydrocarbon Hedge Agreement that is in effect while such
Person or its Affiliate is a Bank, but only while such Person or its Affiliate is a Bank, including
any Interest Rate Contracts and Hydrocarbon Hedge Agreements between such Persons in existence
prior to the Effective Date. No Bank or any Affiliate of a Bank shall have any voting rights under
any Credit Document as a result of the existence of obligations owed to it under any such Interest
Rate Contracts or Hydrocarbon Hedge Agreements.

ARTICLE IX

further, that no amendment, waiver or consent shall, unless in writing and signed by the
Administrative Agent or the Issuing Bank in addition to the Banks required above to take such

Agent, any Bank or the Issuing Bank to exercise, and no delay in exercising, any right hereunder
shall operate as a waiver thereof; nor shall any single or partial exercise of any such right

herein provided are cumulative and not exclusive of any remedies provided by law.

     Section 9.04. Expenses; Indemnity; Damage Waiver.

          (a) Costs and Expenses. The Borrower shall pay (i) all reasonable out-of-pocket

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

disbursements of any outside counsel for the Administrative Agent, any Bank or the Issuing Bank),
in connection with the enforcement or protection of its rights (A) in connection with this
Agreement and the other Credit Documents, including its rights under this Section, or (B) in
connection with the Advances made or Letters of Credit issued hereunder, including all such
out-of-pocket expenses incurred during any workout, restructuring or negotiations in respect of
such Advances or Letters of Credit.

          (b) Indemnification by the Borrower. The Borrower shall indemnify the Administrative
Agent (and any sub-agent thereof), the Collateral Agent, the Bookrunner, the Lead Arranger, the
Syndication Agent, any Co-Documentation Agent, each Bank and the Issuing Banks, 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 outside counsel for any Indemnitee),
incurred by any Indemnitee or asserted against any Indemnitee by any third party or by the Borrower
or any other Subsidiary arising out of, in connection with, or as a result of (i) the execution or
delivery of this Agreement, any other Credit Document or any agreement or instrument contemplated
hereby or thereby, the performance by the parties hereto of their respective obligations hereunder
or thereunder or the consummation of

-76-

 

the transactions contemplated hereby or thereby, (ii) any Advance or Letter of Credit or the
use or proposed 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, whether brought by a third party or by the Borrower or any other Guarantor, and
regardless of whether any Indemnitee is a party thereto, in all cases, whether or not caused by
or arising, in whole or in part, out of the negligence of the Indemnitee; provided
that such indemnity shall not, as to any Indemnitee, be available to the extent that such losses,
claims, damages, liabilities or related expenses (x) are determined by a court of competent
jurisdiction by final and nonappealable judgment to have resulted from the gross negligence or
willful misconduct of such Indemnitee or (y) result from a claim brought by the Borrower or any
other Subsidiary against an Indemnitee for breach in bad faith of such Indemnitee’s obligations
hereunder or under any other Credit Document, if the Borrower or such Subsidiary has obtained a
final and nonappealable judgment in its favor on such claim as determined by a court of competent
jurisdiction.

          (c) Reimbursement by Banks. To the extent that the Borrower for any reason fails to
indefeasibly pay any amount required under subsection (a) or (b) of this Section to be paid by it
to the Administrative Agent (or any sub-agent thereof), the Issuing Bank or any Related Party of
any of the foregoing, each Bank severally agrees to pay to the Administrative Agent (or any such
sub-agent), the Issuing Bank or such Related Party, as the case may be, such Bank’s Pro Rata Share
(determined as of the time that the applicable unreimbursed expense or indemnity payment is sought)
of such unpaid amount, provided that the unreimbursed expense or indemnified loss, claim,
damage, liability or related expense, as the case may be, was incurred by or asserted against the
Administrative Agent (or any such sub-agent) or the Issuing Bank in its capacity as such, or
against any Related Party of any of the foregoing acting for the Administrative Agent (or any such
sub-agent) or Issuing Bank in connection with such capacity. The obligations of the Banks under
this subsection (c) are subject to the provisions of Section 2.02(f).

          (d) Waiver of Consequential Damages, Etc. To the fullest extent permitted by
applicable law, the Borrower shall not assert, and hereby waives, any claim against any Indemnitee,
on any theory of liability, for special, indirect, consequential or punitive damages (as opposed to
direct or actual damages) arising out of, in connection with, or as a result of, this Agreement,
any other Credit Document or any agreement or instrument contemplated hereby, the transactions
contemplated hereby or thereby, any Advance or Letter of Credit or the use of the proceeds thereof.
No Indemnitee referred to in subsection (b) above shall be liable for any damages arising from the
use by unintended recipients of any information or other materials distributed by it through
telecommunications, electronic or other information transmission systems in connection with this
Agreement or the other Credit Documents or the transactions contemplated hereby or thereby.

-77-

 

          (e) Payments. All amounts due under this Section shall be payable not later than ten
Business Days after demand therefor.

          (f) Survival. The agreements in this Section shall survive the resignation of the
Administrative Agent (and the Issuing Bank), the replacement of any Bank, the termination of the
aggregate Commitments and the repayment, satisfaction or discharge of all the other Obligations.

     Section 9.05. Binding Effect. This Agreement shall become effective when it shall
have been executed by the Borrower, the Administrative Agent and the Banks and thereafter shall be
binding upon and inure to the benefit of the Borrower, the Administrative Agent, the Issuing Bank
and each Bank and their respective successors and assigns, except that the Borrower shall not have
the right to assign its rights or delegate its duties under this Agreement or any interest in this
Agreement without the prior written consent of each Bank.

     Section 9.06. Bank Assignments and Participations.

          (a) Assignments. Any Bank may assign to one or more banks or other entities all or
any portion of its rights and obligations under this Agreement (including, without limitation, all
or a portion of its Commitments, the Advances owing to it, and the participation interest in the
Letter of Credit Obligations held by it); provided, however, that (i) each such
assignment shall be of a constant, and not a varying, percentage of all of such Bank’s rights and
obligations assigned under this Agreement (including, without limitation, its obligations to make
Advances), (ii) the amount of the Commitments and Advances of such Bank being assigned pursuant to
each such assignment (determined as of the date of the Assignment and Assumption with respect to
such assignment) shall be, if to an entity other than a Bank, not less than $5,000,000.00 and shall
be an integral multiple of $1,000,000.00, (iii) each such assignment shall be to an Affiliate, an
Approved Fund or an Eligible Assignee, (iv) the parties to each such assignment shall execute and
deliver to the Administrative Agent, for its acceptance and recording in the Register, an
Assignment and Assumption, together with the Notes (if any) subject to such assignment, and (v)
each Eligible Assignee (other than the Eligible Assignee of the Administrative Agent) shall pay to
the Administrative Agent a $3,500 administrative fee. Upon such execution, delivery, acceptance
and recording, from and after the effective date specified in each Assignment and Assumption, which
effective date shall be at least three Business Days after the execution thereof (unless waived by
the Administrative Agent), (a) the assignee thereunder shall be a party hereto for all purposes
and, to the extent that rights and obligations hereunder have been assigned to it pursuant to such
Assignment and Assumption, have the rights and obligations of a Bank hereunder and (b) such Bank
thereunder shall, to the extent that rights and obligations hereunder have been assigned by it
pursuant to such Assignment and Assumption, relinquish its rights and be released from its
obligations under this Agreement (and, in the case of an Assignment and Assumption covering all or
the remaining portion of such Bank’s rights and obligations under this Agreement, such Bank shall
cease to be a party hereto).

          (b) Term of Assignments. By executing and delivering an Assignment and Assumption,
the Bank thereunder and the assignee thereunder confirm to and agree with each other and the other
parties hereto as follows: (i) other than as provided in such Assignment and

-78-

 

Assumption, such Bank makes no representation or warranty and assumes no responsibility with
respect to any statements, warranties or representations made in or in connection with this
Agreement or the execution, legality, validity, enforceability, genuineness, sufficiency of value
of this Agreement or any other instrument or document furnished pursuant hereto; (ii) such Bank
makes no representation or warranty and assumes no responsibility with respect to the financial
condition of the Borrower or the Guarantors or the performance or observance by the Borrower or the
Guarantors of any of their obligations under this Agreement or any other instrument or document
furnished pursuant hereto; (iii) such assignee confirms that it has received a copy of this
Agreement, together with copies of the financial statements referred to in Section 4.05 and such
other documents and information as it has deemed appropriate to make its own credit analysis and
decision to enter into such Assignment and Assumption; (iv) such assignee will, independently and
without reliance upon the Administrative Agent, such Bank or any other Bank and based on such
documents and information as it shall deem appropriate at the time, continue to make its own credit
decisions in taking or not taking action under this Agreement; (v) such assignee appoints and
authorizes the Administrative Agent to take such action as agent on its behalf and to exercise such
powers under this Agreement as are delegated to the Administrative Agent by the terms hereof,
together with such powers as are reasonably incidental thereto; and (vi) such assignee agrees that
it will perform in accordance with their terms all of the obligations which by the terms of this
Agreement are required to be performed by it as a Bank.

          (c) The Register. The Administrative Agent shall maintain at its address referred to
in Section 9.02 a copy of each Assignment and Assumption delivered to and accepted by it and a
register for the recordation of the names and addresses of the Banks and the Commitments of, and
principal amount of the Advances owing to, each Bank from time to time (the “Register”).
The entries in the Register shall be conclusive and binding for all purposes, absent manifest
error, and the Borrower, the Administrative Agent, the Issuing Bank, and the Banks may treat each
Person whose name is recorded in the Register as a Bank hereunder for all purposes of this
Agreement. The Register shall be available for inspection by the Borrower or any Bank at any
reasonable time and from time to time upon reasonable prior notice.

          (d) Procedures. Upon its receipt of an Assignment and Assumption executed by a Bank
and an Eligible Assignee, together with the Notes subject to such assignment, the Administrative
Agent shall, if such Assignment and Assumption has been completed and is in substantially the form
of the attached Exhibit D, (i) accept such Assignment and Assumption, (ii) record the
information contained therein in the Register, and (iii) give prompt notice thereof to the
Borrower.

          (e) Participations. Each Bank may at any time, without the consent of, or notice to,
the Borrower or the Administrative Agent, sell participations to any Person (other than a natural
person or the Borrower or any of the Borrower’s Affiliates or Subsidiaries) (each, a
“Participant”) in or to all or a portion of its rights and obligations under this Agreement
(including, without limitation, all or a portion of its Commitments, the Advances owing to it, its
participation interest in the Letter of Credit Obligations, and the Notes held by it);
provided, however, that (i) such Bank’s obligations under this Agreement
(including, without limitation, its Commitments to the Borrower hereunder) shall remain unchanged,
(ii) such Bank shall remain solely responsible to the other parties hereto for the performance of
such obligations, (iii) such Bank shall remain the holder of any such Notes for all purposes of
this Agreement, (iv) the

-79-

 

Borrower, the Administrative Agent, and the Issuing Bank and the other Banks shall continue to
deal solely and directly with such Bank in connection with such Bank’s rights and obligations under
this Agreement, and (v) such Bank shall not require the participant’s consent to any matter under
this Agreement, except for change in the principal amount of the Notes, reductions in fees or
interest (in each case to the extent subject to such participation), releasing all or substantially
all of the Collateral (other than pursuant to Section 9.18), or extending the Termination Date
(provided that, in any case in which a participant has the right to approve any amendment, waiver
or consent as described above in this clause (v), such Bank shall retain (and hereby agrees to
exercise) the right to repurchase the participation of such participant if such participant does
not approve any such amendment, waiver or consent). The Borrower hereby agrees that participants
shall have the same rights under Sections 2.10, 2.11, 2.12(b) and 9.04 as a Bank to the extent of
their respective participations.

     Section 9.07. Treatment of Certain Information; Confidentiality. Each of the
Administrative Agent, the Banks and the Issuing Bank agrees to maintain the confidentiality of the
Information (as defined below), except that Information may be disclosed (a) to its Affiliates and
to its and its Affiliates’ respective partners, directors, officers, employees, agents, advisors
and representatives (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 purporting to have
jurisdiction over it (including any self-regulatory authority, such as the National Association of
Insurance Commissioners), (c) to the extent required by applicable laws or regulations or by any
subpoena or similar legal process, (d) to any other party hereto, (e) in connection with the
exercise of any remedies hereunder or under any other Credit Document or any action or proceeding
relating to this Agreement or any other Credit Document or the enforcement of rights hereunder or
thereunder, (f) subject to an agreement containing provisions substantially the same as those of
this Section, to (i) any assignee of or Participant in, or any prospective assignee of or
Participant in, any of its rights or obligations under this Agreement or (ii) any actual or
prospective counterparty (or its advisors) to any swap or derivative transaction relating to the
Borrower and its obligations, (g) with the consent of the Borrower or (h) to the extent such
Information (x) becomes publicly available other than as a result of a breach of this Section or
(y) becomes available to the Administrative Agent, any Bank, the Issuing Bank or any of their
respective Affiliates on a nonconfidential basis from a source other than the Borrower.

     For purposes of this Section, “Information” means all information received from the
Borrower or any Subsidiary relating to the Borrower or any Subsidiary or any of their respective
businesses, other than any such information that is available to the Administrative Agent, any Bank
or the Issuing Bank on a nonconfidential basis prior to disclosure by the Borrower or any
Subsidiary, provided that, in the case of information received from the Borrower or any
Subsidiary after the date hereof, such information is clearly identified at the time of delivery as
confidential. Any Person required to maintain the confidentiality of Information as provided in
this Section shall be considered to have complied with its obligation to do so if such Person has
exercised the same degree of care to maintain the confidentiality of such Information as such
Person would accord to its own confidential information.

     Section 9.08. Execution in Counterparts. This Agreement may be executed in any number
of counterparts and by different parties hereto in separate counterparts, each of which

-80-

 

when so executed shall be deemed to be an original and all of which taken together shall
constitute one and the same agreement.

     Section 9.09. Survival of Representations and Warranties. All representations and
warranties made hereunder and in any other Credit Document or other document delivered pursuant
hereto or thereto or in connection herewith or therewith shall survive the execution and delivery
hereof and thereof. Such representations and warranties have been or will be relied upon by the
Administrative Agent and each Bank, regardless of any investigation made by the Administrative
Agent or any Bank or on their behalf and notwithstanding that the Administrative Agent or any Bank
may have had notice or knowledge of any Default at the time of any Advance or issuance of Letter of
Credit, and shall continue in full force and effect as long as any Advance or any other Obligation
hereunder shall remain unpaid or unsatisfied or any Letter of Credit shall remain outstanding.

     Section 9.10. Severability. In case one or more provisions of this Agreement or the
other Credit Documents shall be invalid, illegal or unenforceable in any respect under any
applicable law, the validity, legality and enforceability of the remaining provisions contained
herein or therein shall not be affected or impaired thereby.

     Section 9.11. Payments Set Aside. To the extent that any payment by or on behalf of
the Borrower is made to the Administrative Agent, the Issuing Bank or any Bank, or the
Administrative Agent, the Issuing Bank or any Bank exercises its right of setoff, and such payment
or the proceeds of such setoff or any part thereof is subsequently invalidated, declared to be
fraudulent or preferential, set aside or required (including pursuant to any settlement entered
into by the Administrative Agent, the Issuing Bank or such Bank in its discretion) to be repaid to
a trustee, receiver or any other party, in connection with any proceeding under any Debtor Relief
Law or otherwise, then (a) to the extent of such recovery, the obligation or part thereof
originally intended to be satisfied shall be revived and continued in full force and effect as if
such payment had not been made or such setoff had not occurred, and (b) each Bank and the Issuing
Bank severally agrees to pay to the Administrative Agent upon demand its applicable share (without
duplication) of any amount so recovered from or repaid by the Administrative Agent, plus interest
thereon from the date of such demand to the date such payment is made at a rate per annum equal to
the Federal Funds Rate from time to time in effect. The obligations of the Banks and the Issuing
Bank under clause (b) of the preceding sentence shall survive the payment in full of the
Obligations and the termination of this Agreement

     Section 9.12. Guaranties. The Administrative Agent and each of the Banks hereby
consent to the terms and conditions of the Amended and Restated Subsidiary Guaranties executed by
each of the Guarantors on the date hereof.

     Section 9.13. Usury Not Intended. It is the intent of the Borrower, the
Administrative Agent and the Banks in the execution and performance of this Agreement and the other
Credit Documents to contract in strict compliance with applicable usury laws, including conflicts
of law concepts, governing the Advances of the Banks including such applicable laws of the State of
Texas and the United States of America from time-to-time in effect. In furtherance thereof, the
Administrative Agent, the Banks and the Borrower stipulate and agree that none of the terms and
provisions contained in this Agreement or the other Credit Documents shall ever be construed to

-81-

 

create a contract to pay, as consideration for the use, forbearance or detention of money,
interest at a rate in excess of the Maximum Rate and that for purposes hereof “interest” shall
include the aggregate of all charges which constitute interest under such laws that are contracted
for, charged or received under this Agreement and the other Credit Documents; and in the event
that, notwithstanding the foregoing, under any circumstances the aggregate amounts taken, reserved,
charged, received or paid on the Advances, include amounts which by applicable law are deemed
interest which would exceed the Maximum Rate, then such excess shall be deemed to be a mistake and
the Bank receiving same shall credit the same on the principal of its Advances (or if its Advances
shall have been paid in full, refund said excess to the Borrower). In the event that the maturity
of the Obligations is accelerated by reason of any election of the holder thereof resulting from
any Event of Default under this Agreement or otherwise, or in the event of any required or
permitted prepayment, then such consideration that constitutes interest may never include more than
the Maximum Rate and excess interest, if any, provided for in this Agreement or otherwise shall be
canceled automatically as of the date of such acceleration or prepayment and, if theretofore paid,
shall be credited on the Advances (or, if the Advances shall have been paid in full, refunded to
the Borrower of such interest). The provisions of this Section shall control over all other
provisions of this Agreement or the other Credit Documents which may be in apparent conflict
herewith. In determining whether or not the interest paid or payable under any specific
contingencies exceeds the Maximum Rate, the Borrower, the Administrative Agent and the Banks shall
to the maximum extent permitted under applicable law amortize, prorate, allocate and spread in
equal parts during the period of the full stated term of the Advances, all amounts considered to be
interest under applicable law at any time contracted for, charged, received or reserved in
connection with the Obligations.

     Section 9.14. Waiver of Jury; Consent to Jurisdiction. Each party hereto hereby
irrevocably 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 any other Credit Document or the transactions contemplated hereby or thereby (whether
based on contract, tort or any other theory). Each party hereto (a) certifies that no
representative, agent or attorney of any other person has represented, expressly or otherwise, that
such other person 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 and the other Credit Documents by, among other things, the mutual waivers and
certifications in this section. Each such Party hereby irrevocably submits to the nonexclusive
jurisdiction of the United States district court for the northern district of Texas and of any
Texas state court sitting in Dallas, Texas for purposes of all legal proceedings arising out of or
relating to this Agreement, the other Credit Documents, and the transactions contemplated
thereby.

     Section 9.15. Governing Law. This Agreement, the Notes and the other Credit Documents
shall be governed by, and construed and enforced in accordance with, the laws of the State of
Texas. Without limiting the intent of the parties set forth above, (a) Chapter 15, Subtitle 3,
Title 79, of the Revised Civil Statutes of Texas, 1925, as amended (relating to revolving loans and
revolving tri-party accounts), shall not apply to this Agreement, the Notes,

-82-

 

or the transactions contemplated hereby and (b) to the extent that any Bank may be subject to
Texas law limiting the amount of interest payable for its account, such Bank shall utilize the
indicated (weekly) rate ceiling from time to time in effect as provided in Chapter 303 of the Texas
Finance Code, as amended (formerly known as the indicated (weekly) rate ceiling in Article
5069-1.04 of the Revised Civil Statutes of Texas).

     Section 9.16. Credit Documents. To the extent the specific terms and provisions of
this Credit Agreement expressly conflict with the specific terms and provisions of any of the other
Credit Documents, the specific terms and provisions of this Credit Agreement shall control.

     Section 9.17. Existing Indebtedness. The indebtedness of the Borrower evidenced under
this Agreement and the other Credit Documents is given in renewal, extension, modification but not
in extinguishment or discharge of, a portion of the indebtedness evidenced by the Notes executed by
the Predecessor Borrower each dated June 18, 2004, in the aggregate principal amount of
$200,000,000 executed by the Predecessor Borrower to the order of the lenders named therein, each
bearing interest and being due and payable as therein provided.

     Section 9.18. Release of Collateral. If after the Effective Date (a) the Borrower has
senior unsecured long-term debt outstanding (or if no such senior unsecured long-term debt is
outstanding that is rated by S&P or Moody’s, the Borrower has a corporate debt rating) that (i) is
rated by S&P and all such debt is rated at or above BB+ by S&P and such rating shall be the only
rating of the Borrower with respect to such debt; (ii) is rated by Moody’s and all such debt is
rated at or above Ba1 by Moody’s and such rating shall be the only rating of the Borrower with
respect to such debt; or (iii) is rated by S&P and Moody’s and all such debt is rated at or above
BB+ by S&P and Ba1 by Moody’s (a “Ratings Increase”), and (b) so long as no Default or
Event of Default shall have occurred and then be continuing at such time, then the Collateral shall
be released from the Liens created by the Security Documents and all obligations (other than those
expressly stated to survive such termination) of the Collateral Agent, the Borrower and each
Guarantor thereunder shall terminate, all without delivery of any instrument or performance of any
act by any party, and all rights to the Collateral shall revert to the Borrower and its respective
Subsidiaries; provided however, that (A) the Holders shall also grant a similar
release of Collateral, (B) the Borrower and its Subsidiaries shall grant the Administrative Agent
and the Banks a negative pledge on the assets of the Borrower and its Subsidiaries, except for
Liens permitted by Section 6.02, and shall not grant a negative pledge to any other creditor other
than the Holders and (C) the obligations of the Borrower arising under this Agreement and the
Credit Documents rank pari passu and equal in right of payment with all of the other Debt of the
Borrower, which is not by its terms secured by any assets of the Borrower and its Subsidiaries, and
which is not subordinate in right of payment to any other Debt of the Borrower or its Subsidiaries.
At the request and expense of the Borrower following any such termination and release, the
Collateral Agent shall deliver to the Borrower or such respective Subsidiary any Collateral held by
the Collateral Agent under the Security Documents, and shall execute and deliver to the Borrower or
such Subsidiary such documents as such Person shall reasonably request to evidence such termination
and release. Notwithstanding the foregoing, if subsequent to such Rating Increase, the Borrower
has senior unsecured long-term debt outstanding that (i) is rated by Standard & Poor’s and all such
debt is rated below BB+ by S&P and such rating shall be the only rating of the Borrower; (ii) is
rated by Moody’s and all such debt is rated below Ba1 by Moody’s and such rating shall be the only
rating of the Borrower; or (iii) is rated by S&P and

-83-

 

Moody’s and all such debt is rated below BB+ by Standard & Poor’s and Ba1 by Moody’s, then, at
the expense of the Borrower, the Borrower shall promptly, or such cause each of its Subsidiaries to
promptly, execute and deliver to the Collateral Agent such security agreements, amendments to this
Agreement, other documents and legal opinions, as the Collateral Agent and the Lenders may
reasonably request or deem necessary in connection with the foregoing grant of a security interest,
in order to cause the Collateral to be subject to the Liens created by the Security Documents as of
the Effective Date, and the Company shall execute and deliver such security agreements, amendments
to this Agreement, other documents and legal opinions, as the Agent and the Lenders may reasonably
request in connection with the foregoing grant of a security interest, and the provisions of this
Section 9.18 shall not apply to any future Ratings Increase.

     Section 9.19. Assignment and Assumption. Effective as of the Effective Date, the
Predecessor Borrower assigns and transfers all its rights, title, interest, liabilities and
obligations to the Borrower under the Existing Credit Agreement as if the Borrower had originally
executed the Credit Agreement. The Borrower hereby expressly assumes the obligations of the
Predecessor Borrower under the Existing Credit Agreement and each of the other Credit Documents to
which the Predecessor Borrower was a party. The Borrower hereby agrees to be bound by the terms of
the Agreement and to perform all of the obligations of the Predecessor Borrower in respect thereof
as if the Existing Credit Agreement had been contracted originally by the Borrower.

     Section 9.20. USA PATRIOT Act Notice. Each Bank that is subject to the Act (as
hereinafter defined) and the Administrative Agent (for itself and not on behalf of any Bank) hereby
notifies the Borrower that pursuant to the requirements of the USA Patriot Act (Title III of Pub.
L. 107-56 (signed into law October 26, 2001)) (the “Act”), it is required to obtain, verify
and record information that identifies the Borrower, which information includes the name and
address of the Borrower and other information that will allow such Bank or the Administrative
Agent, as applicable, to identify the Borrower in accordance with the Act.

     Pursuant to section 26.02 of the Texas business and commerce code, a credit agreement in
which the amount involved in the credit agreement exceeds $50,000 in value is not enforceable
unless the credit agreement is in writing and signed by the party to be bound or that party’s
authorized representative.

     The rights and obligations of the parties to an agreement subject to the preceding
paragraph shall be determined solely from the written credit agreement, and any prior oral
agreements between the parties are superseded by and merged into the credit agreement. This
written Agreement and the Credit Documents, as defined in this Agreement, represent the final
agreement among the parties and may not be contradicted by evidence of prior, contemporaneous, or
subsequent oral agreements of the parties.

     There are no unwritten oral agreements between the parties.

aggregate principal amount of $10,000,000 (the “Existing Series B Notes”), and the Prior Issuer’s
6.96% Senior Secured Notes, Series C, due June 18, 2014, in the aggregate principal amount of

Existing Series B Notes, the “Existing Notes”). The Prior Issuer is a wholly owned subsidiary of
the Company and both are part of a common enterprise. The Company is (a) primarily and
unconditionally liable for the existing

 

 

obligations of the Prior Issuer under the Existing Shelf Agreement pursuant to that certain
Limited Partner Guaranty Agreement executed by it of even date with the Existing Shelf Agreement
and (b) a beneficiary of the proceeds of the Existing Notes issued by the Prior Issuer under the
Existing Shelf Agreement by virtue of (i) distributions made to it by the Prior Issuer and (ii)
investments made in the Prior Issuer for the benefit of the Company. The Prior Issuer and the
Company have advised Prudential and the Existing Holders that the Company wishes to assume the
obligations of the Prior Issuer under the Existing Shelf Agreement and the Existing Notes and amend
and restate the Existing Note Agreement as hereinafter provided. Subject to the terms and
conditions hereto, Prudential and the Existing Holders are willing to agree to this request of the
Company and the Prior Issuer.

          1B. Authorization of Series B Notes. The Company will authorize the issue of its 6.88% Senior
Secured Notes, Series B, due July 1, 2010 (the “Series B Notes”), in the aggregate principal amount
of $10,000,000, to be dated the most recent date to which interest has been paid on the Existing
Series B Notes, to mature July 1, 2010, to bear interest on the unpaid balance thereof from the
date thereof until the principal thereof shall have become due and payable at the rate of 6.88% per
annum and on the occurrence and during the continuation of an Event of Default at the rate
specified therein, to be substantially in the form of Exhibit A-2 hereto and to be issued upon
exchange for the Existing Series B Notes. The term “Series B Notes” as used herein shall include

such Series C Note pursuant to any such provision.

          1D. Authorization of Issue of Shelf Notes. The Company will authorize the issue of its senior
secured promissory notes (the “Shelf Notes”) in the aggregate principal amount of $10,000,000; to
be dated the date of issue thereof; to mature, in the case of each Shelf Note so issued, no more
than 10 years after the date of original issuance thereof; to have an average life, in the case of
each Shelf Note so issued, of no more than 8 years after the date of original issuance thereof; to

Shelf Note. Notes which have (i) the same final maturity, (ii) the same principal prepayment
dates, (iii) the same principal prepayment amounts (as a percentage of the original principal
amount of each Note), (iv) the same interest rate, (v) the same interest payment periods, and (vi)
the same original date of issuance are herein called a “Series” of Notes. Capitalized terms used

          1E. Assumption and Amendment and Restatement of Existing Notes. The Company hereby
irrevocably, absolutely, unconditionally and expressly assumes (i) due and punctual payment of all
of the principal of, interest on, Yield-Maintenance Amount (if any) with respect to, and all other
payments due under or relating to the Existing Notes or the Existing Note Agreement. The Company
covenants that its debts, liabilities and obligations assumed pursuant to this paragraph 1E shall
be those of a primary obligor and not a guarantor, surety or secondary obligor.

          1F. Amendment and Restatement of Existing Notes and Existing Shelf Agreement and Issuance of
Notes. Subject to the terms and conditions herein set forth, the Company, the Prior Issuer,
Prudential and the Existing Holders agree that, effective on the Restatement Date, (i) the Existing
Series A Notes will be amended and restated in their entirety to be a like principal amount of
Series A Notes having the terms described in paragraph 1A hereof and to be in the form of Exhibit

principal amount of the Existing Notes held by such Existing Holder being so amended and restated,
registered in the name of such Existing Holder and in the denominations specified in the Purchaser
Schedule

3

 

attached hereto. The Notes issued under this paragraph 1F are given in exchange and
substitution for, and not as payment of the indebtedness evidenced by, the Existing Notes being
amended and restated pursuant to this paragraph 1F, (ii) merely re-evidence the indebtedness
evidenced by the Existing Notes, and (iii) are not intended to constitute a novation or discharge
of the indebtedness evidenced by the Existing Notes. Any Note issued in exchange for any Existing
Notes shall carry the rights to unpaid interest which was carried on the Existing Note for which
such Note was issued in exchange, so that neither gain nor loss of interest shall result from any
such exchange.

          2. PURCHASE AND SALE OF SHELF NOTES.

          2A. Facility. Prudential is willing to consider, in its sole discretion and within limits
which may be authorized for purchase by Prudential Affiliates from time to time, the purchase of
Shelf Notes pursuant to this Agreement. The willingness of Prudential to consider such purchase of
Shelf Notes is herein called the “Facility”. At any time, the aggregate principal amount of Shelf
Notes stated in paragraph 1D, minus the aggregate principal amount of Shelf Notes purchased
and sold pursuant to this Agreement prior to such time, minus the aggregate principal
amount of Accepted Notes (as hereinafter defined) which have not yet been purchased and sold
hereunder prior to such time is herein called the “Available Facility Amount” at such time.
NOTWITHSTANDING THE WILLINGNESS OF PRUDENTIAL TO CONSIDER PURCHASES OF SHELF NOTES BY PRUDENTIAL
AFFILIATES, THIS AGREEMENT IS ENTERED INTO ON THE EXPRESS UNDERSTANDING THAT NEITHER PRUDENTIAL NOR
ANY PRUDENTIAL AFFILIATE SHALL BE OBLIGATED TO MAKE OR ACCEPT OFFERS TO PURCHASE SHELF NOTES, OR TO
QUOTE RATES, SPREADS OR OTHER TERMS WITH RESPECT TO SPECIFIC PURCHASES OF SHELF NOTES, AND THE
FACILITY SHALL IN NO WAY BE CONSTRUED AS A COMMITMENT BY PRUDENTIAL OR ANY PRUDENTIAL AFFILIATE.

          2B. Issuance Period. Shelf Notes may be issued and sold pursuant to this Agreement until the
earlier of (i) June 18, 2007 and (ii) the thirtieth day after Prudential shall have given to the
Company, or the Company shall have given to Prudential, written notice stating that it elects to
terminate the issuance and sale of Shelf Notes pursuant to this Agreement (or if such thirtieth day
is not a Business Day, the Business Day next preceding such thirtieth day). The period during
which Shelf Notes may be issued and sold pursuant to this Agreement is herein called the “Issuance
Period”.

          2C. Periodic Spread Information. Provided no Default or Event of Default exists, not later
than 9:30 A.M. (New York City local time) on a Business Day during the Issuance Period if there is
an Available Facility Amount on such Business Day, the Company may request by telecopier or
telephone, and Prudential will, to the extent reasonably practicable, provide to the Company on
such Business Day (or, if such request is received after 9:30 A.M. (New York City local time) on
such Business Day, on the following Business Day), information (by telecopier or telephone) with
respect to various spreads at which Prudential Affiliates might be interested in purchasing Shelf
Notes of different average lives; provided, however, that the Company may not make
such requests more frequently than once in every five Business Days or such other period as shall
be mutually agreed to by the Company and Prudential. The amount

4

 

and content of information so provided shall be in the sole discretion of Prudential but it is
the intent of Prudential to provide information which will be of use to the Company in determining
whether to initiate procedures for use of the Facility. Information so provided shall not
constitute an offer to purchase Shelf Notes, and neither Prudential nor any Prudential Affiliate
shall be obligated to purchase Shelf Notes at the spreads specified. Information so provided shall
be representative of potential interest only for the period commencing on the day such information
is provided and ending on the earlier of the fifth Business Day after such day and the first day
after such day on which further spread information is provided. Prudential may suspend or
terminate providing information pursuant to this paragraph 2C for any reason, including its
determination that the credit quality of the Company has declined since the date of this Agreement.

          2D. Request for Purchase. The Company may from time to time during the Issuance Period make
requests for purchases of Shelf Notes (each such request being a “Request for Purchase”). Each
Request for Purchase shall be made to Prudential by telecopier or overnight delivery service, and
shall, unless otherwise expressly accepted by Prudential, (i) specify the aggregate principal
amount of Shelf Notes covered thereby, which shall not be less than $10,000,000 and not be greater
than the Available Facility Amount at the time such Request for Purchase is made, (ii) specify the
principal amounts, final maturities, principal prepayment dates and amounts and interest payment
periods (quarterly or semi-annual in arrears) of the Shelf Notes covered thereby, (iii) specify the
use of proceeds of such Shelf Notes, (iv) specify the proposed day for the closing of the purchase
and sale of such Shelf Notes, which shall be a Business Day during the Issuance Period not less
than 10 days and not more than 25 days after the making of such Request for Purchase, (v) specify
the number of the account and the name and address of the depository institution to which the
purchase prices of such Shelf Notes are to be transferred on the Closing Day for such purchase and
sale, (vi) certify that the representations and warranties contained in paragraph 8 are true on and
as of the date of such Request for Purchase and that there exists on the date of such Request for
Purchase no Event of Default or Default, (vii) specify the Designated Spread for such Shelf Notes
and (viii) be substantially in the form of Exhibit B attached hereto. Each Request for
Purchase shall be in writing and shall be deemed made when received by Prudential.

          2E. Rate Quotes. Not later than five Business Days after the Company shall have given
Prudential a Request for Purchase pursuant to paragraph 2D, Prudential may, but shall be under no
obligation to, provide to the Company by telephone or telecopier, in each case between 9:30 A.M.
and 1:30 P.M. New York City local time (or such later time as Prudential may elect) interest rate
quotes for the several principal amounts, maturities, principal prepayment schedules, and interest
payment periods of Shelf Notes specified in such Request for Purchase. Each quote shall represent
the interest rate per annum payable on the outstanding principal balance of such Shelf Notes, at
which a Prudential Affiliate would be willing to purchase such Shelf Notes at 100% of the principal
amount thereof.

          2F. Acceptance. Within 30 minutes after Prudential shall have provided any interest rate
quotes pursuant to paragraph 2E or such other period as Prudential may specify to the Company (such
period being the “Acceptance Window”), the Company may, subject to paragraph 2G, elect to accept
such interest rate quotes as to not less than $10,000,000 aggregate principal amount of the Shelf
Notes specified in the related Request for Purchase. Such election

5

 

shall be made by an Authorized Officer of the Company notifying Prudential by
telephone or telecopier within the Acceptance Window that the Company elects to accept such
interest rate quotes, specifying the Notes (each such Shelf Note being an “Accepted Note”) as to
which such acceptance (an “Acceptance”) relates. The day the Company notifies an Acceptance with
respect to any Accepted Notes is herein called the “Acceptance Day” for such Accepted Notes. Any
interest rate quotes as to which Prudential does not receive an Acceptance within the Acceptance
Window shall expire, and no purchase or sale of Shelf Notes hereunder shall be made based on such
expired interest rate quotes. Subject to paragraph 2G and the other terms and conditions hereof,
the Company agrees to sell to a Prudential Affiliate, and Prudential agrees to cause the purchase
by a Prudential Affiliate of, the Accepted Notes at 100% of the principal amount of such Shelf
Notes. As soon as practicable following the Acceptance Day, the Company, Prudential and each
Prudential Affiliate which is to purchase any such Accepted Notes will execute a confirmation of
such Acceptance substantially in the form of Exhibit C attached hereto (a “Confirmation of
Acceptance”). If the Company should fail to execute and return to Prudential within two Business
Days following receipt thereof a Confirmation of Acceptance with respect to any Accepted Notes,
Prudential may at its election at any time prior to its receipt thereof cancel the closing with
respect to such Accepted Notes by so notifying the Company in writing.

          2G. Market Disruption. Notwithstanding the provisions of paragraph 2F, if Prudential shall
have provided interest rate quotes pursuant to paragraph 2E and thereafter prior to the time an
Acceptance with respect to such quotes shall have been notified to Prudential in accordance with
paragraph 2F the domestic market for U.S. Treasury securities or derivatives shall have closed or
there shall have occurred a general suspension, material limitation, or significant disruption of
trading in securities generally on the New York Stock Exchange or in the domestic market for U.S.
Treasury securities or derivatives, then such interest rate quotes shall expire, and no purchase or
sale of Shelf Notes hereunder shall be made based on such expired interest rate quotes. If the
Company thereafter notifies Prudential of the Acceptance of any such interest rate quotes, such
Acceptance shall be ineffective for all purposes of this Agreement, and Prudential shall promptly
notify the Company that the provisions of this paragraph 2G are applicable with respect to such
Acceptance.

          2H. Closing.

          2H(1). Shelf Note Closings. Not later than 11:30 A.M. (New York City local time) on the
Closing Day for any Accepted Notes, the Company will deliver to each Purchaser listed in the
Confirmation of Acceptance relating thereto at the offices of Schiff Hardin LLP, 6600 Sears Tower,
Chicago, Illinois 60606 the Accepted Notes to be purchased by such Purchaser in the form of one or
more Shelf Notes in authorized denominations as such Purchaser may request for each Series of
Accepted Notes to be purchased on the Closing Day, dated the Closing Day and registered in such
Purchaser’s name (or in the name of its nominee), against payment of the purchase price thereof by
transfer of immediately available funds for credit to the Company’s account specified in the
Request for Purchase of such Shelf Notes.

          2H(2). Rescheduled Closings If the Company fails to tender to any Purchaser the Accepted
Notes to be purchased by such Purchaser on the scheduled Closing Day for such Accepted Notes as
provided above in this paragraph 2H, or any of the conditions specified in

6

 

paragraph 3 shall not have been fulfilled by the time required on such scheduled Closing Day,
the Company shall, prior to 1:00 P.M., New York City local time, on such scheduled Closing Day
notify Prudential (which notification shall be deemed received by each Purchaser) in writing
whether (x) such closing is to be rescheduled (such rescheduled date to be a Business Day during
the Issuance Period not less than one Business Day and not more than 30 Business Days after such
scheduled Closing Day (the “Rescheduled Closing Day”) and certify to Prudential (which
certification shall be for the benefit of each Purchaser) that the Company reasonably believes that
it will be able to comply with the conditions set forth in paragraph 3 on such Rescheduled Closing
Day and that the Company will pay the Delayed Delivery Fee in accordance with paragraph 2I(2) or
(y) such closing is to be canceled as provided in paragraph 2I(3). In the event that the Company
shall fail to give such notice referred to in the preceding sentence, Prudential (on behalf of each
Purchaser) may at its election, at any time after 1:00 P.M., New York City local time, on such
scheduled Closing Day, notify the Company in writing that such closing is to be canceled as
provided in paragraph 2I(3). Notwithstanding anything to the contrary appearing in this Agreement,
the Company may elect to reschedule a closing with respect to any given Accepted Notes on not more
than one occasion, unless Prudential shall have otherwise consented in writing.

          2I. Fees.

          2I(1). Issuance Fee The Company will pay to each Purchaser in immediately available funds a
fee (the “Issuance Fee”) on each Closing Day in an amount equal to 0.25% of the aggregate principal
amount of Shelf Notes sold to such Purchaser on such Closing Day.

          2I(2). Delayed Delivery Fee If the closing of the purchase and sale of any Accepted Note is
delayed for any reason (other than if the Company has satisfied all of the conditions in paragraph
3 with respect to the purchase of such Accepted Notes and the Purchasers fail to purchase such
Accepted Notes) beyond the original Closing Day for such Accepted Note, the Company will pay to the
Purchaser of such Accepted Note on the Cancellation Date or actual closing date of such purchase
and sale a fee (the “Delayed Delivery Fee”) calculated as follows:

(BEY - MMY) X DTS/360 X PA

where “BEY” means Bond Equivalent Yield, i.e., the bond equivalent yield per annum of such Accepted
Note, “MMY” means Money Market Yield, i.e., the yield per annum on a commercial paper investment of
the highest quality selected by Prudential on the date Prudential receives notice of the delay in
the closing for such Accepted Note having a maturity date or dates the same as, or closest to, the
Rescheduled Closing Day or Rescheduled Closing Days (a new alternative investment being selected by
Prudential each time such closing is delayed); “DTS” means Days to Settlement, i.e., the number of
actual days elapsed from and including the original Closing Day with respect to such Accepted Note
to but excluding the date of such payment; and “PA” means Principal Amount, i.e., the principal
amount of the Accepted Note for which such calculation is being made. In no case shall the Delayed
Delivery Fee be less than zero. Nothing contained herein shall obligate any Purchaser to purchase
any Accepted Note on any day other than the Closing Day for such Accepted Note, as the same may be
rescheduled from time to time in compliance with paragraph 2H.

7

 

          2I(3). Cancellation Fee If the Company at any time notifies Prudential in writing that the
Company is canceling the closing of the purchase and sale of any Accepted Note, or if Prudential
notifies the Company in writing under the circumstances set forth in the penultimate sentence of
paragraph 2H(2) that the closing of the purchase and sale of such Accepted Note is to be canceled,
or if the closing of the purchase and sale of such Accepted Note is not consummated on or prior to
the last day of the Issuance Period (the date of any such notification, or the last day of the
Issuance Period, as the case may be, being the “Cancellation Date”), the Company will pay the
Purchasers in immediately available funds an amount (the “Cancellation Fee”) calculated as follows:

PI X PA

where “PI” means Price Increase, i.e., the quotient (expressed in decimals) obtained by dividing
(a) the excess of the ask price (as determined by Prudential) of the Hedge Treasury Note(s) on the
Cancellation Date over the bid price (as determined by Prudential) of the Hedge Treasury Notes(s)
on the Acceptance Day for such Accepted Note by (b) such bid price; and “PA” has the meaning
specified in paragraph 2I(2). The foregoing bid and ask prices shall be as reported by TradeWeb
LLC (or, if such data for any reason ceases to be available through TradeWeb LLC, any publicly
available source of similar market data). Each price shall be rounded to the second decimal place.
In no case shall the Cancellation Fee be less than zero.

          3. CONDITIONS OF AMENDMENT AND RESTATEMENT AND CLOSING. The effectiveness of the amendment
and restatement of the Existing Notes and the Existing Shelf Agreement pursuant to paragraph 1F
hereof is subject to the satisfaction, on the Restatement Date, of, and the obligation of any

Business Days prior to the prepayment date, specifying such prepayment date, specifying the
aggregate principal amount of the Notes to be prepaid on such date, identifying each Note held by
such Holder, and the principal amount of each such Note, to be prepaid on such date and stating
that such prepayment is to be made pursuant to paragraph 4B. Notice of prepayment having been

          4F. Offer to Prepay Notes in the Event of Asset Dispositions and Debt Issuance.

          (i) Notice of Offer to Prepay Notes. The Company will, at least 15 days prior to (a)
the receipt by the Company or any of its Subsidiaries of Net Cash Proceeds from any Asset
Disposition in excess of $20,000,000 or any Recovery Event in excess of $20,000,000 (except (1) to
the extent a Reinvestment Notice shall be delivered in respect of such Asset Disposition or
Recovery Event and (2) cash receipts in the ordinary course of business of the applicable
recipient), (b) each Reinvestment Prepayment Date, and (c) the receipt by the Company or any of its
Subsidiaries of any Net Cash Proceeds from the issuance or incurrence of any Debt for borrowed
money (excluding any Debt incurred in accordance with paragraph 6C(2)), give written notice thereof
to each Holder. Such notice shall contain and constitute an offer to prepay the Notes as described in paragraph 4F(iii) and shall be accompanied by the
certificate described in paragraph 4F(vi). For purposes of calculating whether the Net Cash

13

 

Proceeds received from an Asset Disposition exceed $20,000,000 or from a Recovery Event exceed
$20,000,000, such proceeds shall be determined as of the date of the applicable Asset Disposition
or Recovery Event, whether or not received on such date, but no such amount shall be required to be
applied to prepayment of the Notes pursuant to this paragraph 4F until received by the applicable
Person. The provisions of this paragraph 4F do not constitute a consent to the consummation of any
Asset Disposition not permitted by paragraph 6C(5) or a consent to the issuance or incurrence of
any Debt by the Company or any of its Subsidiaries not otherwise permitted hereunder.

          (ii) Notice of Acceptance of Offer under Paragraph 4F(i). If the Company shall at any
time receive an acceptance to an offer to prepay Notes under paragraph 4F(i) from some, but not
all, of the Holders, then the Company will, within two Business Days after the receipt of such
acceptance, give written notice of such acceptance to each other Holder which has notified the
Company that it requests to receive notices under this paragraph 4F(ii).

          (iii) Offer to Prepay Notes. The offer to prepay Notes contemplated by paragraph
4F(i) shall be an offer to prepay, in accordance with and subject to this paragraph 4F, on the date
the Company or any Subsidiary shall receive any Net Cash Proceeds (in the case of an offer to
prepay given as a result of clauses (a) or (c) of paragraph 4F(i)) or on the Reinvestment
Prepayment Date (in the case of an offer to prepay given as a result of clause (b) of paragraph
4F(i)) (the “Proposed Prepayment Date”), a principal amount of the Notes held by each Holder (in
this case only, “Holder” in respect of any Note registered in the name of a nominee for a disclosed
beneficial owner shall mean such beneficial owner) that is equal to the product of (x) the amount
of the Net Cash Proceeds described in clauses (a) or (c) of paragraph 4F(i) (in the case of an
offer to prepay given as a result of such clauses) or the Reinvestment Prepayment Amount with
respect to the Reinvestment Event relating to the Reinvestment Prepayment Date (in the case of an
offer to prepay even as a result of clause (b) of paragraph 4F(i)) and (y) a fraction, the
numerator of which is the outstanding principal amount of Notes held by such Holder on such
Proposed Prepayment Date and the denominator of which is the sum of the outstanding principal
amount of all Bank Obligations on such Proposed Prepayment Date plus the sum of the outstanding
principal amount of all Notes on such Proposed Prepayment Date.

          (iv) Rejection; Acceptance. A Holder may accept the offer to prepay made pursuant to
paragraph 4F(i) by causing a notice of such acceptance to be delivered to the Company prior to the
Proposed Prepayment Date. A failure by a Holder to so respond to an offer to prepay made pursuant
to this paragraph 4F prior to the Proposed Prepayment Date shall be deemed to constitute a
rejection of such offer by such Holder.

          (v) Prepayment. Prepayment of the Notes to be prepaid pursuant to this paragraph 4F
shall be at 100% of the principal amount so prepaid, together with interest on such Notes accrued
to the date of prepayment and, (i) with respect to a prepayment as a result of an Asset Disposition
or a Recovery Event, to the extent that the aggregate principal amount of the Notes prepaid
pursuant to this paragraph 4F as a result of all Asset Dispositions or Recovery Events would exceed
$20,000,000, the Yield-Maintenance Amount, if any, with respect to the principal amount of the Notes being prepaid, to the extent the principal amount of the Notes
being prepaid, together with the aggregate principal amount of Notes previously prepaid

14

 

pursuant to this paragraph 4F as a result of Asset Dispositions or Recovery Events, would exceed $20,000,000
and (ii) with respect to a prepayment as a result of the issuance or incurrence of any Debt for
borrowed money, the Yield maintenance Amount, if any, with respect to each such Note. The
prepayment shall be made on the Proposed Prepayment Date. The principal amount of any Note prepaid
pursuant to this paragraph 4F shall be applied and reduce the required prepayments of such Note
referred to in paragraph 4A hereof in the inverse order of their scheduled due dates.

          (vi) Officer’s Certificate. Each offer to prepay the Notes pursuant to this paragraph
4F shall be accompanied by a certificate, executed by a Responsible Officer of the Company and
dated the date of such offer, specifying (i) the Proposed Prepayment Date, (ii) the date that such
offer is made pursuant to this paragraph 4F, (iii) the principal amount of each Note offered to be
prepaid, (iv) the interest and the Yield-Maintenance Amount, if any, that would be due on each Note
offered to be prepaid, (v) that the conditions of this paragraph 4F have been fulfilled, and (vi)
in reasonable detail, a description of the event giving rise to such offer to prepay and the
details of the calculation of the amount of the Notes offered to be prepaid.

          5. AFFIRMATIVE COVENANTS. During the Issuance Period and so long thereafter as any Note or
any amount under any Loan Document shall remain unpaid, the Company agrees to comply with the

17

 

owned or hereafter acquired,
other than Liens permitted by the provisions of paragraph 6C(1) (unless prior written consent to
the creation or assumption thereof shall have been obtained pursuant to paragraph 11C), make or

          5E. Preservation of Legal Existence, Etc. The Company will preserve and maintain, and cause
each Subsidiary to preserve and maintain, its legal existence, rights (charter and statutory) and

partner, board of directors or equivalent body of the Company or such Subsidiary determines that
the preservation thereof is no longer desirable in the conduct of the business of the Company or
such Subsidiary, as applicable, and if the loss thereof is not disadvantageous in any material
respect to the Holders.

          5F. Maintenance of Properties, Etc. Except as otherwise permitted by paragraph 6C(5), the
Company will maintain and preserve, and cause each Subsidiary to maintain and preserve, all of its
material properties that are necessary for the conduct of its business in good working order and
condition, ordinary wear and tear excepted.

          5G. Compliance with Laws, Etc. The Company will comply, and cause each Subsidiary to comply,
with all Governmental Rules the noncompliance with which could reasonably be expected to have a
Material Adverse Effect.

          5H. Payment of Taxes, Etc. The Company will pay and discharge, and cause each Subsidiary to
pay and discharge, before the same become delinquent, (a) all federal, state and other material
taxes, assessments and governmental charges or levies imposed upon or against it or its property
and (b) all material lawful claims that, if unpaid, might by law become a Lien upon its property;
provided, however, that neither the Company nor any Subsidiary shall be required to pay or
discharge any such tax, assessment, charge, levy or claim that is being contested in good faith
and, in the case of any such tax, assessment, charge or levy, by proper proceedings and as to
which, in all such cases, it is maintaining appropriate reserves in accordance with GAAP.

          5I. Maintenance of Insurance. The Company will maintain, and cause each Subsidiary to
maintain, insurance with responsible and reputable insurance companies or associations in such
amounts and covering such risks (a) as is usually carried by companies engaged in similar

          5K. Transactions with Affiliates. The Company will conduct, and cause each Subsidiary to
conduct, all transactions otherwise permitted under the Loan Documents with any of its Affiliates
(other than the Company or a Guarantor) on terms that are fair and reasonable and no less favorable
to the Company or such Subsidiary than it would obtain in a comparable arms’ length transaction
with a Person not an Affiliate.

          5L. Compliance with Environmental Laws. The Company will (i) comply, and cause each
Subsidiary to comply, with all applicable Environmental Laws and Environmental Permits, except in
such instances in which (a) such requirement of law or order, writ, injunction or decree is being
contested in good faith by the appropriate proceedings diligently conducted, if such contest could
reasonably be expected to cause such non-compliance to not have a Material Adverse Effect or (b)
the failure to comply therewith could not reasonably be expected to have a Material Adverse Effect,
(ii) obtain and renew, and cause each Subsidiary to obtain and renew, when needed all material
Environmental Permits necessary for its operations and properties that, if not obtained and
renewed, could reasonably be expected to have a Material Adverse Effect, (iii) conduct, and cause
each Subsidiary to conduct, any necessary investigation, study, sampling and testing at properties
currently owned and operated by the Company or any Subsidiary in accordance with the requirements
of all applicable Environmental Laws and (iv) undertake, and cause each Subsidiary to undertake,
any cleanup, removal, remedial and other action necessary to remove and clean up all Hazardous
Materials from any of its currently owned or operated properties, in accordance with the material
requirements of all applicable Environmental Laws, the noncompliance with which could reasonably be
expected to have a Material Adverse Effect.

          5M. Environmental Remediation and Indemnification. If at any time any Hazardous Material is
discovered on, under or about any Mortgaged Property or any other property owned or operated by the
Company or any Subsidiary (“Other Property”) and failure to remediate the same would cause the
Company or any Subsidiary to be in violation of any Environmental Law that could reasonably be
expected to have a Material Adverse Effect, the Company will inform the Holders of the same and of
the Company’s proposed remediation program, and the Company or such Subsidiary will, at no cost and
expense to the Collateral Agent or the Holders, and only to the extent of any legal requirement
under applicable Environmental Laws for the Company or such Subsidiary to do so, remediate or
remove such Hazardous Materials from such Mortgaged Property or Other Property or the groundwater
underlying such Mortgaged Property or Other Property in accordance with (i) such remediation
program as a prudent operator would undertake, (ii) the approval of the appropriate Governmental
Persons, if any such approval is required under the applicable Environmental Laws, and (iii) all
applicable Environmental Laws the noncompliance with which could reasonably be expected to have a
Material Adverse Effect. The Company and any Subsidiary shall have the right to contest any notice
or directive by any appropriate Governmental Person to remediate or remove Hazardous Materials from
any Mortgaged Property or Other Property so long as the Company or such Subsidiary diligently
prosecutes such contest to completion and complies with any final order or determination. The
Company shall be solely responsible for, and will indemnify and hold harmless the Collateral Agent
and the Holders and their respective directors, officers, employees, agents, successors and assigns
from and against, any and all losses, damages, demands, claims, causes of action, judgments,
actions, assessments, penalties, costs, expenses and liabilities to the extent that they directly
or indirectly arise out of or are

19

 

attributable to the release of any Hazardous Materials at any Mortgaged Property or Other
Property, including the following: (a) all foreseeable and unforeseeable consequential damages; (b)
the costs of any repair, cleanup or detoxification of any Mortgaged Property or Other Property
required by any applicable Environmental Laws, and the preparation and implementation of any
closure, remedial or other plans required by any applicable Environmental Laws; and (c) all
reasonable costs and expenses incurred by the Collateral Agent or any Holder in connection with
clauses (a) and (b) above, including reasonable attorneys’ fees; provided, however,
that the Company shall not be liable for any of the foregoing if a final, nonappealable judgment by
a court of competent jurisdiction finds that such release of Hazardous Materials resulted from the
gross negligence or willful misconduct of the Collateral Agent or a Holder. The indemnities
provided in this paragraph 5M shall survive the repayment or any other satisfaction of the
Obligations of the Company under the Loan Documents.

          5N. Maintenance of Credit Facility. The Company will at all times maintain a committed
revolving credit facility in an amount of not less than $20,000,000 with a remaining term of at
least 6 months.

          5O. Additional Covenants and Additional Defaults. If the Company or any Subsidiary enters
into, assumes or otherwise becomes bound or obligated under any agreement (including amendments of
the Bank Agreement) evidencing, securing, guaranteeing or otherwise relating to the Bank
Obligations that contains one or more Additional Covenants or Additional Defaults, the terms of
this Agreement shall, without any further action on the part of the Company or any of the holders
of the Notes, be deemed to be amended automatically to include each Additional Covenant and each
Additional Default contained in such agreement. The Company further covenants to promptly execute
and deliver at its expense (including the reasonable fees and expenses of counsel for the holders
of the Notes) an amendment to this Agreement in form and substance satisfactory to the Required
Holder(s) evidencing the amendment of this Agreement to include such Additional Covenants and
Additional Defaults, provided that the execution and delivery of such amendment shall not
be a precondition to the effectiveness of such amendment as provided for in this paragraph 5O, but
shall merely be for the convenience of the parties hereto.

          5P. Post-Closing Requirements. Within 120 days following the Restatement Date (or such later
date as is acceptable to the Required Holders), the Company shall deliver to the Holders, in form
and substance satisfactory to Required Holders, a copy of the signed order of the Louisiana Public
Service Commission authorizing each of the Louisiana Guarantors to execute Guaranties and Security
Documents with respect to the Obligations under this Agreement (the “Louisiana Public Service
Commission Order”). Notwithstanding anything herein to the contrary, within the 120 day period
following the Restatement Date (or such later date as is acceptable to the Required Holders), the
failure to have obtained the Louisiana Public Service Commission Order shall not be considered to
be a violation of the representations, warranties and covenants in this Agreement or any of the
other Loan Documents so long as the Company is diligently pursuing the same.

          6. NEGATIVE COVENANTS. During the Issuance Period and so long thereafter as any Note or any
amount under any Loan Document shall remain unpaid, the Company agrees to comply with the following
covenants.

20

 

          6A(1). [Intentionally omitted.]

          6A(2). Interest Charge Coverage Ratio. The Company shall not, as of the end of any fiscal

to 1.00; provided however, that during an Acquisition Adjustment Period, the Leverage Ratio shall
not be greater than 4.75 to 1.00.

          6B. Distributions, Etc. The Company will not pay any management fee or similar fee of any
sort to any Affiliate thereof or to any other Person, declare or pay any dividends or
distributions, purchase, redeem, retire, defease or otherwise acquire for value any of its equity
interests or any warrants, rights or options to acquire such equity interests, now or hereafter
outstanding, return any capital to its equity holders as such, or make any distribution of
Property, equity interests, warrants, rights, options, obligations or securities to its
equity-holders as such, or permit any Subsidiary to purchase, redeem, retire, defease or otherwise

thereupon be and become, immediately due and payable together with interest accrued thereon and
together with the Yield-Maintenance Amount, if any, with respect to each Note, without presentment,
demand, protest or notice of any kind (including, without limitation, notice of intent to
accelerate), all of which are hereby waived by the Company.

          The Company acknowledges, and the parties hereto agree, that each Holder has the right to
maintain its investment in the Notes free from repayment by the Company (except as herein
specifically provided for) and that the provision for payment of the Yield-Maintenance Amount by
the Company in the event that the Notes are prepaid or are accelerated as a result of an Event of
Default, is intended to provide compensation for the deprivation of such right under such
circumstances.

          7B. Rescission of Acceleration. At any time after any or all of the Notes shall have been
declared immediately due and payable pursuant to paragraph 7A, the Required Holder(s) may, by
notice in writing to the Company, rescind and annul such declaration and its consequences if (i)
the Company shall have paid all overdue interest on the Notes, the principal of and
Yield-Maintenance Amount, if any, payable with respect to any Notes which have become due otherwise
than by reason of such declaration, and interest on such overdue interest and overdue principal and
Yield Maintenance Amount at the rate specified in the Notes, (ii) the Company shall not have paid
any amounts which have become due solely by reason of such declaration, (iii) all Events of Default
and Defaults, other than non-payment of amounts which have become due solely by reason of such
declaration, shall have been cured or waived pursuant to paragraph 11C, and (iv) no judgment or
decree shall have been entered for the payment of any amounts due pursuant to the Notes or this
Agreement. No such rescission or annulment shall extend to or affect any subsequent Event of
Default or Default or impair any right arising therefrom.

          7C. Notice of Acceleration or Rescission. Whenever any Note shall be declared immediately due
and payable pursuant to paragraph 7A or any such declaration shall be rescinded and annulled
pursuant to paragraph 7B, the Company shall forthwith give written notice thereof to each Holder at
the time outstanding.

          7D. Other Remedies. If any Event of Default or Default shall occur and be continuing, the
Holder of any Note may proceed to protect and enforce its rights under this Agreement, such Note
and the other Loan Documents by exercising such remedies as are available to such Holder in respect
thereof under applicable law, either by suit in equity or by action at law, or both, whether for
specific performance of any covenant or other agreement contained in this Agreement or in aid of
the exercise of any power granted in this Agreement. No remedy conferred in this Agreement upon
any Holder is intended to be exclusive of any other remedy, and each and every such remedy shall be
cumulative and shall be in addition to every other remedy conferred herein or now or hereafter
existing at law or in equity or by statute or otherwise. All amounts recovered by any Holder as the
result of the exercise of such remedies or from distributions or other payments under the
Intercreditor Agreement (after application of amounts thereunder pursuant to the terms of Section
4.3 thereof) shall be applied in accordance with the following priorities (with all partial
payments of amounts owing within each category being allocated ratably in accordance with the
amounts so owing to each Holder): first, to the payment of all fees, indemnities, costs and
expenses then owing to the Holders under the Loan Documents; second, after payment in full
of the amounts set forth in clause first above, to the payment of the Yield-Maintenance
Amount, if any, then owing; third, after payment in full of the amounts set forth in clause
second above, to the payment of all accrued and unpaid interest then owing to the Holders
under the Loan Documents; and fourth, after payment in full of the amounts set forth in
clause third above, to the payment of principal then outstanding under the Notes

          8. REPRESENTATIONS, COVENANTS AND WARRANTIES. The Company represents, covenants and warrants

in good standing under the laws of Delaware, (b) is duly qualified or licensed as a foreign limited
partnership and is in good standing in each jurisdiction in which it owns or leases property or in
which the conduct of its business requires it to so qualify or be licensed, except to the extent

          8B. Financial Statements. The Company has furnished Prudential, each Existing Holder and each
Purchaser of any Accepted Notes with the following financial statements, identified by a principal
financial officer of the Ultimate General Partner: (i)

Consolidated balance sheets of the Company and its Subsidiaries as at December 31, 2003
and as at December 31 in each of the three fiscal years of the Company most recently completed
after December 31, 2003, if any, prior to the date as of which this representation is made or
repeated to such Purchaser (other than fiscal years completed within 120 days prior to such date
for which audited financial statements have not been released) and Consolidated statements of
operations and cash flows and a Consolidated statement of changes in partners’ capital of the
Company and its Subsidiaries for each such year, all such Consolidated statements having been
reported on by KPMG LLP; and (ii) a Consolidated balance sheet of the Company and its Subsidiaries
as at the end of the quarterly period (if any) most recently completed prior to such date and after
the end of such fiscal year (other than quarterly periods completed within 45 days prior to such
date for which financial statements have not been released) and the comparable quarterly period in
the preceding fiscal year and Consolidated statements of operations, cash flows and changes in
partners’ capital for the periods from the beginning of the fiscal years in which such quarterly
periods are included to the end of such quarterly periods, prepared by the Company. Such financial
statements (including any related schedules and/or notes) are true and correct in all material
respects (subject, as to interim statements, to changes resulting from audits and year-end
adjustments), have been prepared in accordance with GAAP consistently followed throughout the
periods involved and show all liabilities, direct and contingent, of the Company and its
Subsidiaries required to be shown in accordance with such principles. The balance sheets fairly
present the condition of the Company and its Subsidiaries as at the dates thereof, and the
statements of operations, cash flows and changes in partners’ capital fairly present the results of
the operations of the Company and its Subsidiaries and their cash flows for the periods indicated.
There has been no material adverse change in the business, property or assets, condition (financial
or otherwise) operations or prospects of the Company and its Subsidiaries taken as a whole since
the end of the most recent fiscal year for which such audited financial statements have been
furnished.

          8C. Actions Pending. There is no action, suit, investigation or proceeding pending or, to the
knowledge of the Company, threatened against the Company or any of its Subsidiaries, or any
properties or rights of the Company or any of its Subsidiaries, by or before any court, arbitrator
or administrative or governmental body which might result in any material adverse change in the
business, property or assets, condition (financial or otherwise), operations or prospects of the
Company and its Subsidiaries taken as a whole. There is no action, suit, investigation or
proceeding pending or, to the knowledge of the Company, threatened against the Company or any of
its Subsidiaries which purports to affect the validity or enforceability of this Agreement, any
Note or any other Loan Document.

          8D. Outstanding Debt. Neither the Company nor any of its Subsidiaries has outstanding any
Debt except as permitted by paragraphs 6A(3) and 6C(2). There exists no default under the
provisions of any instrument evidencing such Debt or of any agreement relating thereto.

          8E. Title to Properties. Each of the Company and its Subsidiaries has good and indefeasible
title to its respective material real properties (other than easements or properties which it
leases) and good title to all of its respective material personal properties and assets, including
the material properties and assets reflected in the most recent audited balance sheet referred to
in paragraph 8B (other than properties and assets disposed of in the ordinary course of

34

 

business), subject to no Lien of any kind except Liens permitted by paragraph 6C(1).
Each of the Company and its Subsidiaries has good and defensible title to all material easements
and rights of way purported to be owned by it. All leases necessary in any material respect for
the conduct of the respective businesses of the Company and its Subsidiaries are valid and
subsisting and are in full force and effect. The Company and each Subsidiary enjoys peaceful and
undisturbed possession of all easements and rights of way necessary in any material respect for the
operation of its Properties. None of the Assigned Agreements, and none of the other documents
creating or affecting any such leasehold, easement or right of way, contains any provisions that
could reasonably be expected to have a Material Adverse Effect or to materially impair the
operation of the business of the Company and its Subsidiaries, taken as a whole.

          8F. Taxes. The Company and each of its Subsidiaries has filed, or there has been filed on its
behalf, or an extension has been obtained for the filing of, all federal, state and other material
tax returns required to be filed before the making of this representation and warranty, and each
has paid all taxes shown thereon to be due, including interest, additions to taxes and penalties,
or has provided adequate reserves in accordance with GAAP for the payment thereof.

          8G. Conflicting Agreements and Other Matters. Neither the Company nor any of its Subsidiaries
is a party to any contract or agreement or subject to any charter or other restriction which
materially and adversely affects its business, property or assets, condition (financial or
otherwise) or operations. Neither the execution nor delivery of this Agreement, the Notes or any
other Loan Document, nor the offering, issuance and sale of the Notes, nor fulfillment of nor
compliance with the terms and provisions hereof and of the other Loan Documents will conflict with,
or result in a breach of the terms, conditions or provisions of, or constitute a default under, or
result in any violation of, or result in the creation of any Lien upon any of the properties or
assets of the Company or any of its Subsidiaries other than the Liens created in favor of the
Collateral Agent for the ratable benefit of the Holders and the Banks pursuant to, the Company
Partnership Agreement or the charter or by-laws or other organizational documents of any of its
Subsidiaries, any award of any arbitrator or any agreement (including any agreement with partners
or members), instrument, order, judgment, decree, statute, law, rule or regulation to which the
Company or any of its Subsidiaries is subject. Neither the Company nor any of its Subsidiaries is
a party to, or otherwise subject to any provision contained in, any instrument evidencing Debt of
the Company or such Subsidiary, any agreement relating thereto or any other contract or agreement
(including its limited partnership agreement or limited liability company agreement) which limits
the amount of, or otherwise imposes restrictions on the incurring of, Debt of the Company of the
type to be evidenced by the Notes, or Debt of the Subsidiaries that are Guarantors of the type to
be evidenced by the Guaranties, except as set forth in the agreements listed in Schedule 8G
attached hereto.

          8H. Offering of Notes. Neither the Company nor any agent acting on its behalf has, directly
or indirectly, offered the Notes or any similar security of the Company for sale to, or solicited
any offers to buy the Notes or any similar security of the Company from, or otherwise approached or
negotiated with respect thereto with, any Person other than institutional investors, and neither
the Company nor any agent acting on its behalf has taken or will take any action which would
subject the issuance or sale of the Notes to the provisions of
Section 5 of the

35

 

Securities Act or to the provisions of any securities or Blue Sky law of any
applicable jurisdiction.

          8I. Use of Proceeds. None of the proceeds of the sale of any Notes will be used, directly or
indirectly, for the purpose, whether immediate, incidental or ultimate, of purchasing or carrying
any “margin stock” as defined in Regulation U (12 CFR Part 221) of the Board of Governors of the
Federal Reserve System (“margin stock”) or for the purpose of maintaining, reducing or retiring any
Debt which was originally incurred to purchase or carry any stock that is then currently a margin
stock or for any other purpose which might constitute the purchase of such Notes a “purpose credit”
within the meaning of such Regulation U, unless the Company shall have delivered to the Purchaser
which is purchasing such Notes, on the Closing Day for such Notes, an opinion of counsel
satisfactory to such Purchaser stating that the purchase of such Notes does not constitute a
violation of such Regulation U. Neither the Company nor any agent acting on its behalf has taken
or will take any action which might cause this Agreement or the Notes to violate Regulation T,
Regulation U or any other regulation of the Board of Governors of the Federal Reserve System or to
violate the Exchange Act, in each case as in effect now or as the same may hereafter be in effect.

          8J. ERISA. No accumulated funding deficiency (as defined in section 302 of ERISA and section
412 of the Code), whether or not waived, exists with respect to any Plan (other than a
Multiemployer Plan). No liability to the PBGC has been or is expected by the Company or any ERISA
Affiliate to be incurred with respect to any Plan (other than a Multiemployer Plan) by the Company,
any Subsidiary or any ERISA Affiliate which is or would be materially adverse to the business,
property or assets, condition (financial or otherwise) or operations of the Company and its
Subsidiaries taken as a whole. Neither the Company, any Subsidiary nor any ERISA Affiliate has
incurred or presently expects to incur any withdrawal liability under Title IV of ERISA with
respect to any Multiemployer Plan which is or would be materially adverse to the business, property
or assets, condition (financial or otherwise) or operations of the Company and its Subsidiaries
taken as a whole. The execution and delivery of this Agreement and the issuance and sale of the
Notes will be exempt from or will not involve any transaction which is subject to the prohibitions
of section 406 of ERISA and will not involve any transaction in connection with which a penalty
could be imposed under section 502(i) of ERISA or a tax could be imposed pursuant to section 4975
of the Code. The representation by the Company in the next preceding sentence is made in reliance
upon and subject to the accuracy of the representation of each Purchaser in paragraph 9B as to the
source of funds to be used by it to purchase any Notes.

          8K. Governmental Consent. Neither the nature of the Company or of any Subsidiary, nor any of
their respective businesses or properties, nor any relationship between the Company or any
Subsidiary and any other Person, nor any circumstance in connection with the offering, issuance,
sale or delivery of the Notes is such as to require any authorization, consent, approval, exemption
or any action by or notice to or filing with any court or administrative or governmental or
regulatory body (other than routine filings after the Closing Day for any Notes with the Securities
and Exchange Commission and/or state Blue Sky authorities) in connection with the execution and
delivery of this Agreement and the other Loan Documents, the offering, issuance, sale or delivery
of the Notes or fulfillment of or compliance with the terms and provisions hereof or of the other
Loan Documents.

properties and facilities have complied at all times and in all respects with all federal, state,

Environmental Laws, failure to receive required permits, failure to comply with the terms and
conditions of such permits or liability in connection with such releases would not, individually or
in the aggregate, have a Material Adverse Effect.

company,” a “subsidiary company” of a “holding company” or an “affiliate” of a “holding company” or

          8P. Disclosure. Neither this Agreement nor any other document, certificate or statement
furnished to any Purchaser by or on behalf of the Company in connection herewith contains any
untrue statement of a material fact or omits to state a material fact necessary in order to make
the statements contained herein and therein, taken as a whole, not misleading. There is no fact
peculiar to the Company or any of its Subsidiaries which materially adversely affects or in the
future may reasonably be expected (so far as the Company can now foresee) to materially adversely
affect the business, property or assets, condition (financial or otherwise) or operations of the

surplus as set forth in the NAIC Annual Statement filed with such Purchaser’s state of
domicile; or

     (ii) the Source is a separate account that is maintained solely in connection with such

91-38 and, except as disclosed by such Purchaser to the Company in writing pursuant to this
clause (iii), no employee benefit plan or group of plans maintained by the same employer or
employee organization beneficially owns more than 10% of all assets allocated to such pooled

definition of “control” in Section V(e) of the QPAM Exemption) owns a 5% or more interest in
the Company and (a) the identity of such QPAM and (b) the names of all employee benefit
plans whose assets are included in such investment fund have been disclosed to the Company
in writing pursuant to this clause (iv); or

     (v) the Source constitutes assets of a “plan(s)” (within the meaning of Section IV of

40

 

          “Discounted Value” means, with respect to the Called Principal of any Note, the amount
obtained by discounting all Remaining Scheduled Payments with respect to such Called Principal from
their respective scheduled due dates to the Settlement Date with respect to such Called Principal,
in accordance with accepted financial practice and at a discount factor (as converted to reflect
the periodic basis on which interest on such Note is payable, if payable other than on a
semi-annual basis) equal to the Reinvestment Yield with respect to such Called Principal.

          “Reinvestment Yield” means, with respect to the Called Principal of any Note, the Designated

Principal for actively traded U.S. Treasury securities having a maturity equal to the Remaining
Average Life of such Called Principal as of such Settlement Date on the Treasury Yield Monitor page
of Standard & Poor’s MMS – Treasury Market Insight (or, if Standard & Poor’s shall cease to report
such yields in MMS – Treasury Market Insight or shall cease to be Prudential Capital Group’s
customary source of information for calculating yield-maintenance amounts on privately placed
notes, then such source as is then Prudential Capital Group’s customary source of such
information), or if such yields shall not be reported as of such time or the yields reported as of
such time shall not be ascertainable, (ii) the Treasury Constant Maturity Series yields reported,

Release H.15(519) (or any comparable successor publication) for actively traded U.S. Treasury
securities having a constant maturity equal to the Remaining Average Life of such Called Principal
as of such Settlement Date. Such implied yield shall be determined, if necessary, by (a)
converting U.S. Treasury bill quotations to bond equivalent yields in accordance with accepted
financial practice and (b) interpolating linearly between yields reported for various maturities.
The Reinvestment Yield shall be rounded to that number of decimal places as appears in the coupon
of the applicable Note.

          “Remaining Average Life” means, with respect to the Called Principal of any Note, the number
of years (calculated to the nearest one-twelfth year) obtained by dividing (i) such Called
Principal into (ii) the sum of the products obtained by multiplying (a) each Remaining Scheduled
Payment of such Called Principal (but not of interest thereon) by (b) the number of years
(calculated to the nearest one-twelfth year) which will elapse between the Settlement Date with
respect to such Called Principal and the scheduled due date of such Remaining Scheduled Payment.

          “Remaining Scheduled Payments” means, with respect to the Called Principal of any Note, all

written consent of all of the Holders at the time outstanding, no amendment to or waiver of the
provisions of this Agreement shall change or affect the provisions of paragraph 7A or this
paragraph 11C insofar as such provisions relate to proportions of the principal amount of the
Notes, or the rights of any individual Holder, required with respect to any declaration of Notes to
be due and payable or with respect to any consent, amendment, waiver or declaration, (iii)
with the written consent of Prudential (and not without the written consent of Prudential)
the provisions of paragraph 2 may be amended or waived (except insofar as any such amendment or
waiver would affect any rights or obligations with respect to the purchase and sale of Notes which
shall have become Accepted Notes prior to such amendment or waiver), and (iv) with the
written consent of all of the Purchasers which shall have become obligated to purchase Accepted
Notes of any Series (and not without the written consent of all such Purchasers), any of the
provisions of paragraphs 2 and 3 may be amended or waived insofar as such amendment or waiver would
affect only rights or obligations with respect to the purchase and sale of the Accepted Notes of
such Series or the terms and provisions of such Accepted Notes. Each Holder of any Note at the
time or thereafter outstanding shall be bound by any consent authorized by this paragraph 11C,
whether or not such Note shall have been marked to indicate such consent, but any Notes issued
thereafter may bear a notation referring to any such consent. No course of dealing between the
Company and any Holder nor any delay in exercising any rights hereunder or under any Note shall
operate as a waiver of any rights of any Holder of such Note. As used herein and in the Notes, the
term “this Agreement” and references thereto shall mean this Agreement as it may from time to time
be amended or supplemented.

          11D. Form, Registration, Transfer and Exchange of Notes; Lost Notes. The Notes are issuable
as registered notes without coupons in denominations of at least $100,000, except as may be
necessary to reflect any principal amount not evenly divisible by $100,000. The Company shall keep
at its principal office a register in which the Company shall provide for the registration of Notes
and of transfers of Notes. Upon surrender for registration of transfer of any Note at the
principal office of the Company, the Company shall, at its expense, execute and deliver one or more
new Notes of like tenor and of a like aggregate principal amount, registered in the name of such
transferee or transferees. At the option of the Holder of any Note, such Note may be exchanged for
other Notes of like tenor and of any authorized denominations, of a like aggregate principal
amount, upon surrender of the Note to be exchanged at the principal office of the Company.
Whenever any Notes are so surrendered for exchange, the Company shall, at its expense, execute and
deliver the Notes which the Holder making the exchange is entitled to receive. Each installment of
principal payable on each installment date upon each new Note issued upon any such transfer or
exchange shall be in the same proportion to the unpaid principal amount of such new Note as the
installment of principal payable on such date on the Note surrendered for registration of transfer
or exchange bore to the unpaid principal amount of such Note. No reference need be made in any
such new Note to any installment or installments of principal previously due and paid upon the Note
surrendered for registration of transfer or exchange. Every Note surrendered for registration of
transfer or exchange shall be duly endorsed, or be accompanied by a written instrument of transfer
duly executed, by the Holder of such Note or such Holder’s attorney duly authorized in writing.
Any Note or Notes issued in exchange for any Note or upon transfer thereof shall carry the rights
to unpaid interest and interest to accrue which were carried by the Note so exchanged or
transferred, so that neither

63

 

gain nor loss of interest shall result from any such transfer or exchange. Upon receipt of
written notice from the Holder of any Note of the loss, theft, destruction or mutilation of such
Note and, in the case of any such loss, theft or destruction, upon receipt of such Holder’s
unsecured indemnity agreement, or in the case of any such mutilation upon surrender and
cancellation of such Note, the Company will make and deliver a new Note, of like tenor, in lieu of
the lost, stolen, destroyed or mutilated Note.

          11E. Persons Deemed Owners; Participations. Prior to due presentment for registration of
transfer, the Company may treat the Person in whose name any Note is registered as the owner and
holder of such Note for the purpose of receiving payment of principal of and interest on, and any
Yield-Maintenance Amount payable with respect to, such Note and for all other purposes whatsoever,
whether or not such Note shall be overdue, and the Company shall not be affected by notice to the
contrary. Subject to the preceding sentence, the Holder of any Note may from time to time grant
participations in all or any part of such Note to any Person on such terms and conditions as may be
determined by such Holder in its sole and absolute discretion.

          11F. Survival of Representations and Warranties; Entire Agreement. All representations and
warranties contained herein or made in writing by or on behalf of the Company in connection
herewith shall survive the execution and delivery of this Agreement and the Notes, the transfer by
any Purchaser of any Note or portion thereof or interest therein and the payment of any Note, and
may be relied upon by any Transferee, regardless of any investigation made at any time by or on
behalf of any Purchaser or any Transferee. Subject to the preceding sentence, this Agreement and
the other Loan Documents embody the entire agreement and understanding between the parties hereto
with respect to the subject matter hereof and supersede all prior agreements and understandings
relating to such subject matter.

          11G. Successors and Assigns. All covenants and other agreements in this Agreement contained
by or on behalf of any of the parties hereto shall bind and inure to the benefit of the respective
successors and assigns of the parties hereto (including, without limitation, any Transferee)
whether so expressed or not.

          11H. Independence of Covenants. All covenants hereunder shall be given independent effect so
that if a particular action or condition is prohibited by any one of such covenants, the fact that
it would be permitted by an exception to, or otherwise be in compliance within the limitations of,
another covenant shall not avoid the occurrence of a Default or Event of Default if such action is
taken or such condition exists.

          11I. Notices. All written communications provided for hereunder (other than communications
provided for under paragraph 2) shall be sent by first class mail or nationwide overnight delivery
service (with charges prepaid) and (i) if to any Purchaser, addressed as specified for such
communications in the Purchaser Schedule attached hereto (in the case of the Series A
Notes, the Series B Notes or the Series C Notes) or the Purchaser Schedule attached to the
applicable Confirmation of Acceptance (in the case of any Notes issued after the date hereof) or at
such other address as any such Purchaser shall have specified to the Company in writing, (ii) if to
any other Holder of any Note, addressed to it at such address as it shall have specified in writing
to the Company, or, if any such Holder shall not have so specified
an address, then

64

 

addressed to such Holder in care of the last Holder of such Note which shall
have so specified an address to the Company and (iii) if to the Company, addressed to it at 2501
Cedar Springs, Suite 600, Dallas, Texas 75201, Attention: William W. Davis, provided,
however, that any such communication to the Company may also, at the option of the Person
sending such communication, be delivered by any other means either to the Company at its address
specified above or to any Authorized Officer of the Company. Any communication pursuant to
paragraph 2 shall be made by the method specified for such communication in paragraph 2, and shall
be effective to create any rights or obligations under this Agreement only if, in the case of a
telephone communication, an Authorized Officer of the party conveying the information and of the
party receiving the information are parties to the telephone call, and in the case of a telecopier
communication, the communication is signed by an Authorized Officer of the party conveying the
information, addressed to the attention of an Authorized Officer of the party receiving the
information, and in fact received at the telecopier terminal the number of which is listed for the
party receiving the communication in the Purchaser Schedule or at such other telecopier
terminal as the party receiving the information shall have specified in writing to the party
sending such information.

          11J. Payments Due on Non-Business Days. Anything in this Agreement or the Notes to the
contrary notwithstanding, any payment of principal of or interest on, or Yield-Maintenance Amount
payable with respect to, any Note that is due on a date other than a Business Day shall be made on
the next succeeding Business Day. If the date for any payment is extended to the next succeeding
Business Day by reason of the preceding sentence, the period of such extension shall not be
included in the computation of the interest payable on such Business Day.

          11K. Severability. Any provision of this Agreement which is prohibited or unenforceable in
any jurisdiction shall, as to such jurisdiction, be ineffective to the extent of such prohibition
or unenforceability without invalidating the remaining provisions hereof, and any such prohibition
or unenforceability in any jurisdiction shall not invalidate or render unenforceable such provision
in any other jurisdiction.

          11L. Descriptive Headings. The descriptive headings of the several paragraphs of this
Agreement are inserted for convenience only and do not constitute a part of this Agreement.

          11M. Satisfaction Requirement. If any agreement, certificate or other writing, or any action
taken or to be taken, is by the terms of this Agreement required to be satisfactory to Prudential,
any Purchaser, to any Holder or to the Required Holder(s), then (unless stated otherwise) the
determination of such satisfaction shall be made by Prudential, such Purchaser, such Holder or the
Required Holder(s), as the case may be, in the sole and exclusive judgment (exercised in good
faith) of the Person or Persons making such determination.

          11N. Governing Law. THIS AGREEMENT SHALL BE CONSTRUED AND ENFORCED IN ACCORDANCE WITH, AND
THE RIGHTS OF THE PARTIES SHALL BE GOVERNED BY, THE LAW OF THE STATE OF NEW YORK.

65

 

          11O. Severalty of Obligations. The sales of Notes to the Purchasers are to be several sales,
and the obligations of Prudential and the Purchasers under this Agreement are several obligations.
No failure by Prudential or any Purchaser to perform its obligations under this Agreement shall
relieve any other Purchaser or the Company of any of its obligations hereunder, and neither
Prudential nor any Purchaser shall be responsible for the obligations of, or any action taken or
omitted by, any other such Person hereunder.

          11P. Counterparts. This Agreement may be executed in any number of counterparts, each of
which shall be an original, but all of which together shall constitute one instrument.

          11Q. Binding Agreement. When this Agreement is executed and delivered by the Company and
Prudential, it shall become a binding agreement between the Company and Prudential. This Agreement
shall also inure to the benefit of each Purchaser which shall have executed and delivered a
Confirmation of Acceptance, and each such Purchaser shall be bound by this Agreement to the extent
provided in such Confirmation of Acceptance.

          11R. Waiver of Jury Trial; Consent to Jurisdiction.

     (i) THE COMPANY, PRUDENTIAL AND EACH HOLDER HEREBY KNOWINGLY, VOLUNTARILY, AND
INTENTIONALLY WAIVE ANY RIGHTS THEY MAY HAVE TO A TRIAL BY JURY IN ANY LITIGATION OF ANY
CLAIM WHICH IS BASED HEREON, OR ARISES OUT OF, UNDER, OR IN CONNECTION WITH THIS AGREEMENT,
THE NOTES OR THE OTHER LOAN DOCUMENTS, OR ANY TRANSACTIONS RELATING HERETO OR THERETO, OR
ANY COURSE OF CONDUCT, COURSE OF DEALING, STATEMENTS (WHETHER ORAL OR WRITTEN), OR ACTIONS
OF THE COMPANY, PRUDENTIAL OR THE HOLDERS. THE COMPANY ACKNOWLEDGES THAT THIS PROVISION IS
A MATERIAL INDUCEMENT FOR PRUDENTIAL AND EACH PURCHASER TO BECOME A PARTY TO THIS AGREEMENT
AND TO PURCHASE NOTES HEREUNDER.

     (ii) ANY LEGAL ACTION OR PROCEEDING WITH RESPECT TO THIS AGREEMENT, THE NOTES, THE
OTHER LOAN DOCUMENTS OR ANY TRANSACTIONS RELATING HERETO OR THERETO, OR ANY COURSE OF
CONDUCT, COURSE OF DEALING, STATEMENTS (WHETHER ORAL OR WRITTEN), OR ACTIONS OF THE COMPANY,
PRUDENTIAL OR THE HOLDERS MAY BE BROUGHT IN THE COURTS OF THE STATE OF NEW YORK OR THE
UNITED STATES OF AMERICA FOR THE SOUTHERN DISTRICT OF NEW YORK, AND THE COMPANY HEREBY
ACCEPTS FOR ITSELF AND IN RESPECT OF ITS PROPERTY, GENERALLY AND UNCONDITIONALLY, THE
NONEXCLUSIVE JURISDICTION OF THE AFORESAID COURTS. THE COMPANY, PRUDENTIAL AND EACH HOLDER
HEREBY IRREVOCABLY WAIVE ANY OBJECTIONS, INCLUDING, WITHOUT LIMITATION, ANY OBJECTION TO THE
LAYING OF VENUE OR BASED ON THE GROUNDS OF FORUM NON CONVENIENS, WHICH THEY MAY NOW OR
HEREAFTER HAVE

66

 

TO THE BRINGING OF ANY SUCH ACTION OR PROCEEDING IN SUCH RESPECTIVE JURISDICTIONS.

     (iii) The Company hereby irrevocably consents to service of process on it at the
address provided for notices in paragraph 11I. Any and all service of process and any other
notice in any such action, suit or proceeding shall be effective against the Company if
given by registered or certified mail, return receipt requested, or by any other means or
mail which requires a signed receipt, postage prepaid, mailed to the Company as provided in
the preceding sentence.

          11S. Maximum Interest Payable. The Company, Prudential, each Purchaser and any other Holders
specifically intend and agree to limit contractually the amount of interest payable under this
Agreement, the Notes, the other Loan Documents and all other instruments and agreements related
hereto and thereto to the maximum amount of interest lawfully permitted to be charged under
applicable law. Therefore, none of the terms of this Agreement, the Notes, the other Loan
Documents or any instrument pertaining to or relating to this Agreement, the Notes or the other
Loan Documents shall ever be construed to create a contract to pay interest at a rate in excess of
the maximum rate permitted to be charged under applicable law, and neither Company, any guarantor
nor any other party liable or to become liable hereunder or under the Notes, any guaranty, any
other Loan Document or any other instruments and agreements related hereto and thereto shall ever
be liable for interest in excess of the amount determined at such maximum rate, and the provisions
of this paragraph 11S shall control over all other provisions of this Agreement, any Notes, the
other Loan Documents, any guaranty or any other instrument pertaining to or relating to the
transactions herein contemplated. If any amount of interest taken or received by Prudential, any
Purchaser or any Holder shall be in excess of said maximum amount of interest which, under
applicable law, could lawfully have been collected by Prudential, such Purchaser or such Holder
incident to such transactions, then such excess shall be deemed to have been the result of a
mathematical error by all parties hereto and shall be refunded promptly by the Person receiving
such amount to the party paying such amount, or, at the option of the recipient, credited ratably
against the unpaid principal amount of the Note or Notes held by Prudential, such Purchaser or such
Holder, respectively. All amounts paid or agreed to be paid in connection with such transactions
which would under applicable law be deemed “interest” shall, to the extent permitted by such
applicable law, be amortized, prorated, allocated and spread throughout the stated term of this
Agreement and the Notes. “Applicable law” as used in this paragraph means that law in effect from
time to time which permits the charging and collection of the highest permissible lawful,
nonusurious rate of interest on the transactions herein contemplated, and “maximum rate” as used in
this paragraph means, with respect to each of the Notes, the maximum lawful, nonusurious rates of
interest (if any) which under applicable law may be charged to the Company from time to time with
respect to such Notes.

          11T. Release of Collateral. Prudential, each Purchaser and the Company agree that, effective
upon the Collateral Release Date:

     (i) Prudential and each Purchaser will deliver a direction to the Collateral Agent to
release all Liens in the Collateral securing the Obligations (as defined in the
Intercreditor Agreement) and to terminate all Security Agreements, Mortgages and any

67

 

other instrument or agreement pursuant to which a Lien has been created or arose to
secure any or all of the Obligations (as defined in the Intercreditor Agreement);

     (ii) paragraphs 3A(xi), 3A(xii), 3A(xiii), 3J, 3K, 6C(1)(i), and 7A(xv) of this
Agreement shall no longer be effective and shall be deleted from the Agreement;

     (iii) clause (i) of paragraph 6C(4) of this Agreement shall be amended in its entirety
to read as follows:

     “(i) so long as no Default or Event of Default
has occurred and is continuing or would be caused
thereby, the Company or any Subsidiary may make any
Acquisition; provided, however, that
any such Acquisition shall be permitted only if, (a)
on or before or concurrently with the effectiveness
of such Acquisition and to the extent required by
the Required Holders, the Company delivers to the
Holders (I) guaranties duly executed by the parties
thereto, in form and substance satisfactory to the
Required Holders, and accompanied by UCC searches
and title investigations, (II) such legal opinions
in relation to the documents described in the
foregoing subclause (I) as the Required Holders may
reasonably request, and (III) evidence of Company
authority to enter into, and environmental
assessments with respect to, such Acquisition, (b)
the Company or such Guarantor is the acquiring or
surviving entity, (c) no Default or Event of Default
exists and the Acquisition could not reasonably be
expected to cause a Default or Event of Default, (d)
after giving effect to such Acquisition on a pro
forma basis, the Company would have been in
compliance with all of the covenants contained in
this Agreement, including, without limitation,
paragraph 6A as of the end of the most recent fiscal
quarter, (e) the acquisition target is in the same
or similar line of business as the Company and its
Subsidiaries, (f) the terms of paragraph 6G are
satisfied, and (g) the aggregate amount of cash
(including the proceeds of any Debt permitted to be
incurred under clause (xi) of paragraph 6C(2) or
otherwise hereunder), Permitted Investments and the
remaining unused portion of the commitment under the
Bank Agreement is sufficient to fund such
Acquisition;”;

68

 

     (iv) clause (a) paragraph 8U of the Agreement shall be amended to delete the words “and
Liens in favor of the Collateral Agent” from the second sentence thereof and clause (b) of
paragraph 8U of the Agreement shall be amended to delete the words “, other than in favor of
the Collateral Agent” therefrom;

     (v) the definition of “Assigned Agreements” shall be amended and restated in its
entirety to read as follows:

     “Assigned Agreements” shall mean all
agreements, guaranties, contracts, leases, licenses,
contract rights and rights to payment, including
purchase contracts, sales contracts, transportation
contracts, gathering service agreements, gas
purchase agreements, pipeline lease agreements, gas
marketing agreements and gas processing agreements,
to which the Company or any Subsidiary is a party.

     (vi) the definition of “Loan Documents” shall be amended to delete the words “, the
Security Documents” therefrom.

69

 

          If you are in agreement with the foregoing, please sign the form of acceptance on the enclosed
counterpart of this letter and return the same to the Company, whereupon this letter shall become a
binding agreement between the Company and you.
