In making the calculation contemplated by the preceding sentence, EBITDA
generated or to be generated by such acquired Person, by such acquired Property

Property), during such period computed on the basis of personnel expenses for
employees retained or to be retained by the Borrower and its Subsidiaries in the
operation of such acquired Person, acquired Property or Property under
construction (based on the percentage of completion of construction of such
Property) and non-personnel costs and expenses incurred by the Borrower and its
Subsidiaries in the operation of the Borrower's and its Subsidiaries' business
at similarly situated facilities of the Borrower or any of its Subsidiaries;

forma calculations (and any such pro forma calculations described in this
sentence being hereinafter referred to as "Pro Forma EBITDA"); provided further,
that the Borrower shall not be required to deliver an Approved Consultant's
Report in connection with the El Paso Acquisition. Notwithstanding the
foregoing, such pro forma adjustments to EBITDA with respect to any Property
under construction shall be reduced if such construction is not completed by or
if the estimated date by which such construction to be completed is beyond, a
date that is more than 90 days beyond the Scheduled Completion Date for such
construction, such reduction to be reflected in the next set of financial
statements to be delivered to the Administrative Agent and the Banks on or after
the date such construction is not so completed or it is determined that such
construction will not be so completed and to be in an amount equal to the
product of (i) the applicable percentage reduction rate relating to the number
of days of delay as set forth below and (ii) the amount of the Pro Forma EBITDA
attributable to such Property:

Notwithstanding any provision of this Agreement which may otherwise be to the
contrary, if any lease pursuant to the Eunice Lease Documents is treated under
GAAP as a Capital Lease, then, for all computations of EBITDA hereunder, such

     Section 2.01. Making the Advances.

            (a) Advances. Each Bank severally agrees, on the terms and
conditions set forth in this Agreement, to make Advances to the Borrower from

the Termination Date in an aggregate outstanding amount up to but not to exceed
at any time outstanding its Commitment, as such amount may be reduced pursuant

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

Advances and payments with respect thereto.

subsection (i), each Bank and the Administrative Agent shall maintain in

accounts and records of the Administrative Agent shall control in the absence of
manifest error.

     Section 2.02. Method of Borrowing.

            (a) Notice. Each Borrowing shall be made pursuant to a Notice of
Borrowing (or by telephone notice promptly confirmed in writing by a Notice of

information required therein. In the case of a proposed Borrowing comprised of
Eurodollar Rate Advances, the Administrative Agent shall promptly notify each
Bank of the applicable interest rate under Section 2.07(b). Each Bank shall,
before 2:00 p.m. on the date of such Borrowing, make available for the account

Agent.

            (b) Conversions and Continuations. The Borrower may elect to Convert
or continue any Borrowing under this Section 2.02 by delivering an irrevocable
Notice of Conversion or Continuation to the Administrative Agent at the

at least three Business Days in advance of the

                                      -25-
<PAGE>

proposed Conversion or continuation date in the case of a Conversion to or a
continuation of a Borrowing comprised of Eurodollar Rate Advances and (ii) 1:00
p.m. on the Business Day of the proposed conversion date in the case of a
Conversion to Borrowing comprised of Reference Rate Advance. Each such Notice of
Conversion or Continuation shall be in writing or by telex or telecopier,
confirmed immediately in writing, or other written notice specifying the
information required therein. Promptly after 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 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

                                      -26-
<PAGE>

                  (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
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,

                                      -27-
<PAGE>

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 or any part of the
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.

            (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

                                      -28-
<PAGE>

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. Upon the occurrence of any Asset
Disposition or any Recovery Event (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 the Net Cash Proceeds related thereto, 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 the Net Cash Proceeds received
from an Asset Disposition or from a Recovery Event, 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) Equity Issuance. If the Leverage Ratio of the Borrower
and its Subsidiaries on a Consolidated basis shall exceed 4.00 to 1.00, then
Equity Issuance Proceeds received by the Borrower or any of its Subsidiaries,
shall be applied to prepay the Advances on the date such Equity Issuance
Proceeds are received in an amount equal to the lesser of (A) the amount of such
Equity Issuance Proceeds and (B) the amount necessary to cause the Leverage
Ratio to be 4.00 to 1.00 or less, based on the most recently delivered Financial
Statements; provided that this paragraph shall not apply to Equity Issuance
Proceeds required to be received by the Borrower pursuant to Section 3.01(n).

                  (v) 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

                                      -29-
<PAGE>

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 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 August 27, 2005 from
Bank of America and the Lead Arranger to the Borrower (the "Fee Letter").

                                      -30-
<PAGE>

            (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 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

                                      -31-
<PAGE>

for such Advance to the Eurodollar Rate for such Interest Period plus the
Applicable Margin plus 2.00% per annum, payable on demand.

            (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 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.

                                      -33-

      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 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

                                      -34-
<PAGE>

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 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.

                                      -35-

      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 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

                                      -36-
<PAGE>

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.

            (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.

                                      -37-

            (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; 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 lesser of (i) $300,000,000
and (ii) 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) November 1, 2011;

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

                                      -38-
<PAGE>

                        (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

                  (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

                                      -39-
<PAGE>

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 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 (in
writing or by facsimile promptly confirmed 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. Upon the
issuance of an Auto-Extension Letter of Credit, the Issuing Bank shall promptly
notify the Administrative Agent of the agreed upon Non-Extension Notice Date
with respect to such Letter of Credit. The Administrative Agent shall notify the
Banks of the agreed upon Non-Extension Notice Date with respect to such Letter
of Credit as a part of its regular quarterly report to the Banks concerning
Letters of Credit. 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 November 1, 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 in writing or by
facsimile promptly confirmed 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

                                      -40-
<PAGE>

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. As a part of its regular quarterly report to the Banks concerning
Letters of Credit, the Administrative Agent shall deliver to the Banks notice
that (x) such Letter of Credit or amendment to Letter of Credit has been
delivered, (y) the amount of such Letter of Credit, and (z) the Expiration Date
of such Letter of Credit.

                  (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.

                                      -41-
<PAGE>

                  (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 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

                                      -42-
<PAGE>

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 9.11 (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.

            (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

                                      -43-
<PAGE>

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 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. 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

                                      -44-
<PAGE>

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 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. Any Letter of Credit Application submitted by
the Borrower to the Issuing Bank requesting the issuance, increase, extension,
or other amendment of any Letter of Credit for the account of any Person other
than the Borrower shall constitute a representation and warranty by the Borrower
that such Person is a Subsidiary of the Borrower. The Issuing Bank shall be
entitled to rely upon, and shall not incur any liability for relying upon, such
representation and warranty of the Borrower.

      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);

                                      -45-
<PAGE>

            (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 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 $300,000,000; provided that
(i) any such request for an increase shall be in a minimum amount of
$50,000,000, and (ii) the Borrower may make a maximum of six 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 Bank not
responding within such time period shall be deemed to have declined to increase
its Commitment.

            (c) Notification by Administrative Agent; Additional Banks. The
Administrative Agent shall notify the Borrower of the Banks' responses to each
request made hereunder. To achieve the full amount of a requested increase and
subject to the approval of the Administrative Agent and the Issuing Bank (which
approvals shall not be unreasonably withheld), the Borrower may also invite
additional Eligible Assignees to become Banks pursuant to a joinder agreement in
form and substance satisfactory to the Administrative Agent and its counsel.

                                      -46-

            (d) Effective Date and Allocations. If the aggregate Commitments are
increased in accordance with this Section, the Administrative Agent and the
Borrower shall determine the effective date (the "Increase Effective Date") and
the final allocation of such increase. The Administrative Agent shall promptly
notify the Borrower and the Banks of the final allocation of such increase and
the Increase Effective Date.

            (e) Conditions to Effectiveness of Increase. As a condition
precedent to such increase, the Borrower shall deliver to the Administrative
Agent a certificate of the Borrower and each Guarantor dated as of the Increase
Effective Date (in sufficient copies for each Bank) signed by a Responsible
Officer of such Person (i) certifying and attaching the resolutions adopted by
such Person approving or consenting to such increase, and (ii) in the case of
the Borrower, certifying that, before and after giving effect to such increase,
(A) the representations and warranties contained in Article IV and the other
Credit Documents are true and correct on and as of the Increase Effective Date,
except to the extent that such representations and warranties specifically refer
to an earlier date, in which case they are true and correct as of such earlier
date, and except that for purposes of this Section 2.15, the representations and
warranties contained in Section 4.05 shall be deemed to refer to the most recent
statements furnished pursuant to clauses (c) and (d), respectively, of Section
5.01, and (B) no Default exists. The Borrower shall prepay (but may do so with
proceeds of Advances from any effective increase) any Advances outstanding on
the Increase Effective Date (and pay any additional amounts required pursuant to
Section 2.10) to the extent necessary to keep the outstanding Advances ratable
with any revised Pro Rata Shares arising from any nonratable increase in the
Commitments under this Section.

            (f) Conflicting Provisions. This Section shall supersede any
provisions in Sections 2.09 or 9.01 to the contrary.

Bank for use in connection with the transactions contemplated by the Credit
Documents, taken as a whole with other information, documents, certificates or
written statements furnished therewith, contains any material misstatement of
fact or omits to state a material fact necessary to make the statements

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

would undertake, (b) the approval of the appropriate Governmental Persons, if

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, any Co-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,

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

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.

the Guarantors shall execute such Mortgages and other Security Documents as the

Borrower and the Guarantors shall deliver to the Collateral Agent such other

Agent, a copy of the signed order of the Louisiana Public Service Commission

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.

      Section 5.16. Mortgage Amendments. Upon the earlier to occur of (i) six
months prior to the Termination Date or (ii) if the Collateral Agent reasonably
believes that failure to execute and deliver such amendments could have a

applicable, shall promptly execute and deliver to the Collateral Agent
amendments to each of the existing Mortgages in form and substance reasonably
satisfactory to the Collateral Agent, together with such other documents,
certificates, opinions and agreements as the Collateral Agent may reasonably
request.

Documents within five Business Days after the same becomes due and payable;

            (b) Representation and Warranties. Any representation or warranty

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

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

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

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

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

      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

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, letter of credit fees, and fronting fees owing to the
Administrative Agent, the Issuing Bank, and 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 an Affiliate thereof, or any Hydrocarbon Hedge
Agreement between the Borrower or any Subsidiary and a Bank or an Affiliate
thereof and which are owing to the Administrative Agent, the Collateral Agent,
the Banks and their Affiliates.

                                  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.

                                      -75-

<PAGE>

      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. Upon the receipt of such notice by the
Administrative Agent, the Administrative Agent shall promptly notify the Banks
of the Default described in such notice.

      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

                                      -76-

<PAGE>

with the Borrower, to appoint a successor, which shall be a bank with an office
in the United States, or an Affiliate of any such bank with an office in the
United States. If no such successor shall have been so appointed by the 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

                                      -77-

<PAGE>

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, any Co-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

                                      -78-

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,

            (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

                                  MISCELLANEOUS

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 action, affect the rights or duties of the Administrative Agent or
the Issuing Bank, as the case may be, under this Agreement or any other Credit
Document.

      Section 9.03. No Waiver; Remedies. No failure on the part of the
Administrative 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

      Section 9.04. Expenses; Indemnity; Damage Waiver.

            (a) Costs and Expenses. The Borrower shall pay (i) all reasonable

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.

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

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, except in the case of an assignment of
the entire remaining amount of the assigning Bank's Commitments and Advances at
the time owing to it, (iii) each such assignment shall be to an Affiliate, an
Approved Fund or an Eligible Assignee, (iv) the parties to each such assignment

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),

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

                                      -83-

<PAGE>

other and the other parties hereto as follows: (i) other than as provided in
such Assignment and 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

                                      -84-

<PAGE>

Bank shall remain the holder of any such Notes for all purposes of this
Agreement, (iv) the 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 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 Second 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

                                      -86-

<PAGE>

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 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,

                                      -87-

<PAGE>

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, 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 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 Borrower each
dated March 31, 2005, in the aggregate principal amount of $250,000,000 executed
by the 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 and Moody's, the
Borrower has a corporate debt rating) that is rated at or above BBB- by S&P and
Baa3 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 is either (i) not rated by both S&P and Moody's or (ii) is
rated by S&P and Moody's and all such debt is rated below BBB- by Standard &
Poor's or below Baa3 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

                                      -88-

<PAGE>

Collateral Agent and the Banks 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 Banks 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. Amendment and Restatement. The Borrower, the Administrative
Agent and the Banks have agreed that this Agreement is an amendment and
restatement of the Existing Credit Agreement in its entirety and the terms and
provisions hereof supersede the terms and provisions thereof, and this Agreement
is not a new or substitute credit agreement or novation of the Existing Credit
Agreement.

      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.

          THERE ARE NO UNWRITTEN ORAL AGREEMENTS BETWEEN THE PARTIES.
