                                   ARTICLE II

                              PPA LETTER OF CREDIT

     SECTION 2.1 COMMITMENTS.

     Each Bank irrevocably agrees severally, on the terms and conditions
contained in this Agreement, to participate in the PPA Letter of Credit and in
the Drawing thereunder in the Percentage Interest of such Bank and in an
aggregate amount not to exceed at any time such Bank's Commitment.

     SECTION 2.2 AMOUNT AND TERM OF PPA LETTER OF CREDIT.

     (a) (i) Subject to the terms and conditions contained in this Agreement,
the Issuing Bank irrevocably agrees to issue the PPA Letter of Credit on the
Closing Date for the account of the Company and in a face amount not to exceed
the Stated Amount. The conditions precedent to the Closing Date are set forth in
Section 3.1.

     (ii) On or prior to the date that is 120 days prior to the original
Expiration Date of the PPA Letter of Credit or any extension thereof pursuant to
this Section 2.2(a) (the "NOTICE DATE"), the Agent may on behalf of the Banks in
accordance with Section 2.19(a) extend the original or extended Expiration Date,
as the case may be, of such PPA Letter of Credit for an additional one or more
years beyond the original or extended Expiration Date, as the case may be. The
Agent shall notify the Company, the Collateral Agent and the Power Purchaser of


                                       6
<PAGE>

the Banks' decision regarding such extension on or prior to the applicable
Notice Date. Failure of the Agent to provide the Company, the Collateral Agent
and the Power Purchaser with written notice of renewal on or prior to the
applicable Notice Date in respect of the original Expiration Date or any
extended Expiration Date, as the case may be, or imposition of additional terms
and conditions adverse to the Company (in the Company's reasonable judgment) in
respect of such renewal, shall be deemed to constitute non-renewal of the PPA
Letter of Credit beyond the original or extended Expiration Date, as the case
may be. If the Agent agrees to extend the then current Expiration Date, the
Expiration Date of the PPA Letter of Credit shall, effective upon the giving of
such notice to the Company, be such extended date.

     (b) The Issuing Bank shall have the right, upon the occurrence and during
the continuance of an Event of Default, to deliver to the Collateral Agent and
the Power Purchaser a notice in the form of Annex 2 to the PPA Letter of Credit
(a "TERMINATION NOTICE"), which notice shall be given at least thirty (30) days
prior to the date of termination referred to in such notice.

     (c) The Agent shall, solely for informational purposes, deliver to the
Company a copy of any Termination Notice given to the beneficiary under the PPA
Letter of Credit; PROVIDED, HOWEVER, that the Issuing Bank's ability to
terminate the PPA Letter of Credit shall not be contingent upon the Agent's
delivery to the Company of such notice and that neither the Agent nor the Banks
shall incur any liability whatsoever as a result of the Agent's failure to
deliver such notice to the Company.

     SECTION 2.3 PARTICIPATION IN PPA LETTER OF CREDIT.

     Simultaneously with the issuance of the PPA Letter of Credit, the Issuing
Bank shall be deemed to have sold and transferred to each Bank, and each Bank
shall be deemed to have purchased and received from the Issuing Bank, in each
case irrevocably and without any further action by any party, an undivided
interest and participation in the PPA Letter of Credit, each Drawing and the
other Loan Obligations in respect thereof in an amount equal to such Bank's
Percentage Interest therein. The Agent shall promptly advise each Bank of any
cancellation or other termination of the PPA Letter of Credit and any Drawing;
PROVIDED, HOWEVER, that failure to provide such notice shall not limit or impair
the rights of the Agent hereunder or under the Financing Documents.

     SECTION 2.4 DRAWING AND REIMBURSEMENT.

     The payment by the Issuing Bank of a Drawing shall constitute the making by
the Issuing Bank of a loan to the Company in the amount of such payment. In the
event that a Drawing is not repaid by the Company by 10:00 a.m. (New York City
time), on the day of such Drawing, the Agent shall promptly notify each other
Bank. Each such Bank (including the Issuing Bank in its capacity as a Bank)
shall, on the day of such notification, make a loan to the Company, which shall
be used to repay the applicable portion of the Issuing Bank's loan with respect
to such Drawing, in an amount equal to the amount of such Bank's Percentage
Interest in the Drawing, for application to repay the Issuing Bank (such loan by
a Bank to be referred to as a "PPA LOC LOAN"), and shall deliver to the Agent
for the Issuing Bank's account, on the day of such notification and in
immediately available funds, the amount of such loan. In the event that any Bank
fails to make available to the Agent for the account of the Issuing Bank the
amount of such


                                       7
<PAGE>

PPA LOC Loan, the Issuing Bank shall be entitled to recover such amount on
demand from such Bank together with interest thereon at the Federal Funds Rate
and until such reimbursement is made, the unreimbursed amount of the Issuing
Bank's loan shall be deemed to be a PPA LOC Loan for all purposes under this
Agreement.

     SECTION 2.5 FEES.

     The Company shall pay the following fees to the Agent for the respective
accounts of the Persons specified below:

     (a) from and including the Closing Date, for the respective accounts of the
Banks, a letter of credit fee equal to the product of (x) the average daily
Stated Amount and (y) the Applicable Margin for the letter of credit fee,
payable quarterly in arrears on each Quarterly Date occurring after the Closing
Date; and

     (b) from and including the Closing Date, for the account of the Issuing
Bank, a fronting fee equal to the product of (x) the average daily Stated Amount
and (y) 0.15% per annum, payable quarterly in arrears on each Quarterly Date
occurring after the Closing Date.

     SECTION 2.6 INTEREST.

     (a) RATE. The Company shall pay interest on the unpaid principal amount of
each PPA LOC Loan from the date such PPA LOC Loan is made until such principal
amount has been paid in full as follows:

          (i) BASE RATE LOANS. As to Base Rate Loans, at a rate per annum equal
     to the sum of (x) the Adjusted Base Rate plus (y) the Applicable Margin,
     payable monthly in arrears on the first Business Day of each month;

          (ii) EURODOLLAR RATE LOANS. As to Eurodollar Rate Loans, at a rate per
     annum equal to the sum of (x) the Eurodollar Rate plus (y) the Applicable
     Margin, payable on the last day of the applicable Interest Period or, if
     such Interest Period exceeds three months, at intervals of three months
     from the first day of such Interest Period; and

          (iii) POST-DEFAULT RATE. During an Event of Default (and whether
     before or after judgment), each PPA LOC Loan (whether or not due) and, to
     the maximum extent permitted by Applicable Law, each other amount due and
     payable under the Credit Documents shall bear interest at a rate per annum
     equal to the applicable Post-Default Rate.

     (b) METHOD OF ELECTING INTEREST RATES.

          (i) Each PPA LOC Loan shall constitute a Base Rate Loan unless the
     Company elects otherwise pursuant to the following provisions of this
     Section 2.6(b).

          (ii) Each PPA LOC Loan shall constitute a Base Rate Loan or a
     Eurodollar Rate Loan as the Company may elect in accordance with this
     Section 2.6(b). If no such election is timely made with respect to a PPA
     LOC Loan, such PPA LOC Loan shall


                                       8
<PAGE>

     initially constitute a Base Rate Loan in accordance with Section 2.6(b)(i).
     The Company may from time to time elect to change or continue the interest
     rate borne by each PPA LOC Loan, subject to the conditions set forth below,
     as follows:

               (A) with respect to PPA LOC Loans that are Base Rate Loans, the
          Company may elect to convert all or any portion of such PPA LOC Loans
          to Eurodollar Rate Loans as of any Business Day; and

               (B) with respect to PPA LOC Loans that are Eurodollar Rate Loans,
          the Company may elect to convert all or any portion of such PPA LOC
          Loans to Base Rate Loans or elect to continue all or any portion of
          such PPA LOC Loans as Eurodollar Rate Loans for an additional Interest
          Period, in each case effective on the last day of the then current
          Interest Period applicable to such PPA LOC Loans.

     Each such election shall be made by delivering a notice (a "NOTICE OF
     INTEREST RATE ELECTION") to the Agent (1) in the case of a conversion to or
     continuation of a Eurodollar Rate Loan, not later than 10:00 a.m. (New York
     City time) on the third Business Day prior to the day on which such
     conversion or continuation is to be effective or (2) in the case of a
     conversion to a Base Rate Loan, at any time prior to the day on which such
     conversion is to be effective. Each Notice of Interest Rate Election shall
     be in writing (including facsimile transmission) or by voice, promptly
     confirmed in writing. A Notice of Interest Rate Election may, if it so
     specifies, apply to only a portion of the aggregate principal amount of the
     relevant PPA LOC Loan.

          (iii) Each Notice of Interest Rate Election shall specify:

               (A) the PPA LOC Loan (or portion thereof) together with the
          amount of each thereof, to which such notice applies;

               (B) the date on which the conversion or continuation selected in
          such notice is to be effective, which shall comply with the applicable
          clause of subsection (ii) above;

               (C) if PPA LOC Loans are to be converted, each new type of PPA
          LOC Loan together with the amount thereof, and if such new PPA LOC
          Loans are Eurodollar Rate Loans, the duration of the initial Interest
          Period applicable thereto; and

               (D) if such PPA LOC Loans are to be continued as Eurodollar Rate
          Loans for additional Interest Periods, the duration of such Interest
          Periods.

Each Interest Period specified in a Notice of Interest Rate Election shall
comply with the provisions of the definition of Interest Period. No conversion
into or continuation of a Eurodollar Rate Loan shall be permitted when a Default
or an Event of Default has occurred and is continuing, and if a Default or an
Event of Default has occurred and is continuing, each Eurodollar Rate Loan shall
automatically be converted into a Base Rate Loan on the last day of the then
current Interest Period applicable thereto.


                                       9
<PAGE>

          (iv) A Notice of Interest Rate Election shall not be revocable by the
     Company. If the Company fails to deliver a timely Notice of Interest Rate
     Election to the Agent for any Eurodollar Rate Loan, such PPA LOC Loans
     shall be converted into Base Rate Loans on the last day of the then current
     Interest Period applicable thereto.

          (v) Anything to the contrary in this Agreement notwithstanding, at no
     time shall there be outstanding more than four different Interest Periods
     applicable to the PPA LOC Loans, and Eurodollar Rate Loans that bear a
     single Interest Period shall not be less than $1 million and shall be in
     integral multiples of $100,000.

     (c) FUNDING LOSSES. If the Company makes any payment of principal with
respect to any Eurodollar Rate Loan or any Eurodollar Rate Loan is converted
to a Base Rate Loan on any day other than the last day of an Interest Period
applicable thereto, or if the Company fails to borrow, repay or prepay any
Eurodollar Rate Loan after notice has been given to the Agent in accordance
with the terms hereof, the Company shall reimburse the Agent, for the ratable
account of the Banks, within 30 days after demand for any resulting loss or
expense incurred by them, including any loss incurred in obtaining,
liquidating or employing deposits from third parties. Without prejudice to
the foregoing, the Company shall indemnify the Agent and the Banks against
any direct (as opposed to consequential) loss or expense that the Agent or
the Banks may sustain or incur as a consequence of a failure by the Company
in payment of principal of, or interest on, any Eurodollar Rate Loan, or any
part thereof, including any interest, premium or penalty paid by the Agent or
any Bank to lenders of funds borrowed by it or deposited with it for the
purpose of making or maintaining such Eurodollar Rate Loan. A certificate as
to the amount of any such loss or expense in reasonable detail (specifying
the basis of such loss or expense) shall be promptly submitted by the Agent,
or by any Bank through the Agent, to the Company and shall be conclusive and
binding as to the amount thereof, absent manifest error.

     (d) BASIS FOR DETERMINING INTEREST RATE INADEQUATE OR UNFAIR. If on or
prior to the first day of any Interest Period for any Eurodollar Rate Loan:

          (i) the Agent or any Bank determines, in its reasonable judgment, that
     deposits in Dollars (in the applicable amounts) are not being offered to
     the Agent or such Bank in the relevant market for such Interest Period, or

          (ii) the Agent or such Bank, in its reasonable judgment, shall
     determine that the Eurodollar Rate will not adequately and fairly reflect
     the cost to the Agent or such Bank of funding its Eurodollar Rate Loans for
     such Interest Period,

the Agent, or such Bank through the Agent, shall forthwith give notice thereof
(which notice shall describe in reasonable detail the basis for such
determination) to the Company, whereupon until the Agent, or such Bank through
the Agent, notifies the Company that the circumstances giving rise to such
suspension no longer exist, (A) the obligations of the Agent or such Bank to
make or continue Eurodollar Rate Loans or to convert outstanding PPA LOC Loans
into Eurodollar Rate Loans shall be suspended and (B) each outstanding
Eurodollar Rate Loan or, if only a Bank shall be affected, each Eurodollar Rate
Loan held by such Bank shall be converted into a Base Rate Loan on the last day
of the then current Interest Period applicable thereto.


                                       10
<PAGE>

     (e) MAXIMUM RATE. This Agreement is hereby expressly limited so that in no
contingency or event, whether by reason of acceleration of the maturity of any
indebtedness hereunder or otherwise, shall the interest contracted for or
charged or received by the Banks exceed the maximum amount permissible under
Applicable Law. If, from any circumstance whatsoever, interest would otherwise
be payable to the Banks in excess of the maximum lawful amount, the interest
payable to the Banks shall be reduced to the maximum amount permitted under
Applicable Law, and the amount of interest for any subsequent period, to the
extent less than that permitted by Applicable Law, shall to that extent be
increased by the amount of such reduction.

     SECTION 2.7 REPAYMENT.

     On each Quarterly Date, the Company shall repay the principal amount of
each PPA LOC Loan in accordance with Exhibit D to this Agreement. Each PPA LOC
Loan shall mature and be repaid in full on the applicable PPA LOC Loan Required
Payment Date; PROVIDED that, the Company shall repay on or prior to the
Commercial Operation Date the outstanding principal amount of each PPA LOC Loan,
together with accrued interest to the date of such repayment on the principal
amount, in respect of any Drawing made prior to the Commercial Operation Date,
to the extent funds are available to pay such amounts in accordance with Section
3.9 of the Collateral Agency Agreement.

     SECTION 2.8 PREPAYMENTS.

     The Company may, at any time and from time to time on any Business Day,
upon prior written notice to the Agent not later than 11:00 a.m. (New York City
time), at least one Business Day before the day of any prepayment of the PPA LOC
Loans, such notice stating the proposed date and aggregate principal amount of
the prepayment, and if such notice is given the Company shall, prepay without
premium or penalty, except as provided in Section 2.6(c), the outstanding
principal amounts of the PPA LOC Loans in whole or in part, together with
accrued interest to the date of such prepayment on the principal amount prepaid.

     All prepayments made hereunder shall be applied by the Agent and the Banks
against the principal amount of outstanding PPA LOC Loans in inverse order of
maturity; PROVIDED, that such prepayments shall first be applied to the
prepayment of outstanding Base Rate Loans to the extent thereof and then to the
prepayment of outstanding Eurodollar Rate Loans.

     SECTION 2.9 SECURITY.

     The Obligations shall be secured by the Security Documents, the rights and
remedies in respect of which shall be exercised pursuant to the Collateral
Agency Agreement.

     SECTION 2.10 PAYMENTS.

     (a) The Company shall make each payment hereunder and under the PPA LOC
Loan Note not later than 10:00 a.m. (New York City time), on the day when due to
the Agent at its address set forth in Section 9.2, in Dollars in immediately
available funds. The Agent will promptly thereafter cause to be distributed like
funds relating to the payment of principal (including reimbursement of the
Drawing), interest or fees ratably (other than amounts payable


                                       11
<PAGE>

for the account of the Issuing Bank pursuant to Section 2.5(b), which shall be
payable solely to the Issuing Bank, or payable pursuant to Section 9.4) to the
Banks and like funds relating to the payment of any other amount payable to any
Bank to such Bank, in each case to be applied in accordance with the terms of
this Agreement. The Agent may withhold from any interest payment to any Bank an
amount equal to any applicable withholding tax (including upon the failure of
any Bank to provide the forms or other documentation required under Section
2.17(f)).

     (b) Unless the Agent receives notice from the Company before the date on
which any payment is due to the Banks hereunder that the Company will not make
such payment in full, the Agent may assume that the Company has made such
payment in full to the Agent on such date, and the Agent may, in reliance upon
such assumption, cause to be distributed to each Bank on such due date an amount
equal to the amount then due to such Bank. If and to the extent that the Company
has not so made such payment in full to the Agent on the date on which such
payment is due, each Bank agrees, irrevocably and without qualification or
exception, to repay to the Agent forthwith on demand such amount distributed to
such Bank together with interest thereon, for each day from the date such amount
is distributed to such Bank until the date on which such Bank repays such amount
to the Agent, at the Federal Funds Rate.

     (c) All payments made by the Company to each of the Banks and the Agent
under this Agreement and the PPA LOC Loan Note will be made without set-off,
counterclaim or other defense.

     SECTION 2.11 COMPUTATION OF INTEREST AND FEES.

     All computations of interest and fees hereunder shall be made on the basis
of a year of 360 days 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 calculation and each determination by the Agent of an interest
rate hereunder shall be conclusive and binding for all purposes, absent manifest
error.

     SECTION 2.12 PAYMENTS ON NON-BUSINESS DAYS.

     Whenever any payment hereunder or under the PPA LOC Loan Note is 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.
If no due date is specified for the payment of any amount payable by the Company
hereunder, such amount shall be due and payable not later than 10 Business Days
after receipt by the Company of written demand from the Agent for payment
thereof.

     SECTION 2.13 SHARING OF PAYMENTS, ETC.

     (a) Each Bank agrees that if, as a result of the exercise of a right of
set-off, banker's lien or counterclaim or other similar right or the receipt of
a secured claim, it receives any payment in respect of the PPA LOC Loans or
other Obligations hereunder it shall promptly notify the Agent thereof (and the
Agent shall promptly notify the other Banks). If, as a result of such payment,
such Bank receives a greater percentage of the Obligations owed to it under this
Agreement than the percentage received by any other Bank, such Bank shall
purchase a


                                       12
<PAGE>

participation (which it shall be deemed to have purchased simultaneously upon
the receipt of such payment) in the Obligations then held by such other Banks so
that all such recoveries of principal and interest with respect to all
Obligations owed to each Bank shall be pro rata on the basis of its respective
amount of such Obligations owed to all Banks; PROVIDED, that if all or part of
such proportionately greater payment received by such purchasing Bank is
thereafter recovered by or on behalf of the Company from such Bank, such
purchase shall be rescinded and the purchase price paid for such participation
shall be returned to such Bank to the extent of such recovery, but without
interest.

     (b) Each Bank which receives a secured claim as described in subsection (a)
above shall, to the extent practicable, exercise its rights in respect of such
secured claim in accordance with such subsection (a) and otherwise in a manner
consistent with the rights of the Banks entitled under this Section 2.13 to
share in the benefits of any recovery on such secured claim.

     (c) The Company expressly consents to the foregoing arrangements and agrees
that any holder of a participation in any Obligation so purchased or otherwise
acquired of which the Company has received notice may exercise any and all
rights of set-off, banker's lien or counterclaim with respect to any and all
monies owing by the Company to such holder as fully as if such holder were a
holder of such Obligation in the amount of the participation held by such
holder.

     SECTION 2.14 EVIDENCE OF DEBT.

     (a) The indebtedness of the Company resulting from all PPA LOC Loans shall
be evidenced by this Agreement and the promissory note substantially in the form
of Exhibit B (the "PPA LOC LOAN NOTE"), delivered by the Company to the Agent
for the benefit of the Banks in accordance with the terms hereof.

     (b) The books and accounts of the Agent shall be conclusive evidence,
absent manifest error, of the amounts of the Drawing, all PPA LOC Loans, fees,
interest and other amounts advanced, due, outstanding, payable or paid pursuant
to this Agreement or the PPA LOC Loan Note.

     SECTION 2.15 INCREASED COSTS AND REDUCED RETURNS.

     (a) If, on or after the date hereof, the adoption of any Applicable Law, or
any change therein, or any change in the interpretation or administration
thereof by any Governmental Authority, central bank or comparable agency charged
with the interpretation or administration thereof, or compliance by the Agent or
any Bank with any request or directive (whether or not having the force of law)
of any such authority, central bank or comparable agency:

          (i) shall subject the Agent or such Bank to any tax, duty or other
     charge (other than routine examination fees or Taxes) with respect to the
     Eurodollar Rate Loans, the PPA LOC Loan Note or its obligation to make or
     continue Eurodollar Rate Loans, or shall change the basis of taxation of
     payments to the Agent or any Bank of the principal of or interest on its
     Eurodollar Rate Loans or any other amounts due under this Agreement in
     respect of its Eurodollar Rate Loans or its obligation to make or continue
     Eurodollar Rate Loans (except for changes in the rate of tax on the net
     income of the


                                       13
<PAGE>

     Agent or such Bank imposed by the federal, state or local jurisdiction in
     which the Agent's or such Bank's principal executive office is located); or

          (ii) shall impose, modify or deem applicable any reserve, special
     deposit or similar requirement (including any such requirement imposed by
     the Board of Governors of the Federal Reserve System, but excluding with
     respect to any Eurodollar Rate Loan any such requirement provided in
     Section 2.17(b), against assets of, deposits with or for the account of, or
     credit extended by, the Agent or any Bank or shall impose on the Agent or
     any Bank or on the London interbank market any other condition affecting
     the Eurodollar Rate Loans, the PPA LOC Loan Note or its obligation to
     advance Eurodollar Rate Loans;

and the result of any of the foregoing is to increase the cost to the Agent or
such Bank of making or continuing any Eurodollar Rate Loan or to reduce the
amount of any sum received or receivable by the Agent or such Bank under this
Agreement or under the PPA LOC Loan Note with respect thereto by an amount
deemed by the Agent or such Bank to be material, then the Agent, or such Bank
through the Agent, shall deliver to the Company as promptly as practicable a
certificate setting forth in reasonable detail the additional amounts that the
Agent or such Bank, as the case may be, determines will fully compensate it for
such reduction, increased cost or payment and the basis for the determination of
such amount; PROVIDED, that the Company shall not be obligated to compensate the
Agent or any Bank for the amount of such increased cost incurred with respect to
a period of time prior to the date which is 90 days before the date on which the
Agent first notifies the Company of a claim for such compensation or that an
event had occurred which will entitle the Agent or a Bank to such compensation.
Any such amount claimed by the Agent or any Bank shall, in the case of clause
(i) above, be net of applicable tax savings, if any, directly attributable
thereto. Within 30 days after demand by the Agent, the Company shall pay to the
Agent, for its account or for the account of the applicable Bank, as the case
may be, such additional amount shown as due on any such certificate, absent
manifest error.

     (b) In the event that the Agent or any Bank shall determine (which
determination shall, absent manifest error, be final and conclusive and binding
on all the parties hereto) at any time that the Agent or such Bank is required
to maintain reserves in respect of Eurocurrency Liabilities during any period
during which any PPA LOC Loan owing to it bears interest based on the Eurodollar
Rate (each such period, for the Agent or such Bank, a "EUROCURRENCY RESERVE
PERIOD"), but only in respect of any period during which any reserve shall
actually be maintained by the Agent or such Bank for any Eurodollar Rate Loan as
a result of a reserve requirement applicable to it under Regulation D in
connection with Eurocurrency Liabilities, then the Agent, or such Bank through
the Agent, shall promptly give notice to the Company of such determination, and
the Company shall directly pay to the Agent, for its account or for the account
of the applicable Bank, as the case may be, additional interest on the unpaid
principal amount of such PPA LOC Loan during such Eurocurrency Reserve Period at
a rate PER ANNUM which shall, during each monthly period applicable to such PPA
LOC Loan, be the amount by which (x) the Eurodollar Rate for such monthly period
divided (and rounded upward to the next whole multiple of 1/100 of 1%) by a
percentage equal to 100% minus the then stated maximum rate of all reserve
requirements (including any marginal, emergency, supplemental, special or other
reserves) applicable to the Agent or such Bank in respect of Eurocurrency
Liabilities exceeds (y) the Eurodollar Rate for such monthly period. The Agent,
or such Bank through the Agent, shall


                                       14
<PAGE>

furnish along with such notice a certificate setting forth in reasonable detail
the cost actually incurred to maintain such reserves and the basis for the
determination of such amount; PROVIDED, that the Company shall not be obligated
to compensate the Agent or any Bank for the amount of such increased cost
incurred with respect to a period of time prior to the date which is 90 days
before the date on which the Agent first notifies the Company of a claim for
such compensation or that an event has occurred which will entitle the Agent or
a Bank to such compensation. Additional interest payable pursuant to the
immediately preceding sentence shall be paid by the Company at the time that it
is otherwise required to pay interest in respect of such PPA LOC Loan, or, if
later demanded by the Agent or any Bank, promptly on demand. Each of the Agent
and the Banks agrees that, if notice is given to the Company of the existence of
a Eurocurrency Reserve Period, the Agent, or the applicable Bank through the
Agent, shall promptly notify the Company of any termination thereof, at which
time the Company shall cease to be obligated to pay additional interest to the
Agent or such Bank pursuant to the first sentence of this paragraph until such
time, if any, as a subsequent Eurocurrency Reserve Period shall occur.

     (c) The Agent, and each Bank through the Agent, will promptly notify the
Company of any event of which it has knowledge, occurring after the date hereof,
which will entitle the Agent or such Bank to compensation pursuant to this
Section and will designate a different lending office if such designation will
avoid the need for, or reduce the amount of, such compensation and will not, in
the sole judgment of the Agent or such Bank, be otherwise disadvantageous to the
Agent or such Bank.

     SECTION 2.16 CAPITAL ADEQUACY.

     If the Agent or any Bank shall determine that, after the date hereof, the
adoption of any Applicable Law regarding capital adequacy, or any change
therein, or any change in the interpretation or administration thereof by any
Governmental Authority, central bank or comparable agency charged with the
interpretation or administration thereof, or any request or directive regarding
capital adequacy (whether or not having the force of law) of any such authority,
central bank or comparable agency, has or would have the effect of reducing the
rate of return on capital of the Agent or such Bank or its holding company as a
consequence of the Agent's or such Bank's obligations hereunder to a level below
that which the Agent or such Bank could have achieved but for such adoption,
change, request or directive (taking into consideration its policies with
respect to capital adequacy) by an amount deemed by the Agent or such Bank to be
material, then the Agent, or such Bank through the Agent, shall deliver to the
Company as promptly as practicable (but in no event later than 120 days after
the Agent or such Bank has actual knowledge of such claim for capital adequacy)
a certificate setting forth in reasonable detail the amount being charged by the
Agent or such Bank and the basis for the determination of such amount. Within 30
days after the delivery of such certificates by the Agent, the Company shall pay
to the Agent, for its account or for the account of the applicable Bank, as the
case may be, the amount shown as due on any such certificate.

     SECTION 2.17 TAXES.

     (a) Payments by the Company to the Agent and the Banks under this Agreement
and the PPA LOC Loan Note will be made free and clear of and without deduction
for Taxes, other than Taxes based on the net income of the Agent or any Bank
(including franchise taxes imposed


                                       15
<PAGE>

in lieu of net income taxes) imposed by (i) the United States federal
government, (ii) the jurisdiction where the Agent or such Bank is organized or
has its principal office or (iii) the jurisdiction of the branch of such Bank
maintaining any PPA LOC Loan or the branch of the Agent through which it renders
its services as the Agent ("EXCLUDED TAXES"). If the Company is required by law
to deduct Taxes (other than Excluded Taxes) from such a payment, then the sum
payable under the instrument to which the payment relates will be increased so
that such deduction does not result in a diminution in the amount the Agent or
any Bank actually receives.

     (b) To the extent permitted by law, without duplication of amounts paid by
the Company under Section 2.17(a), the Company hereby indemnifies and holds
harmless the Agent and each Bank from and against, and agrees to reimburse the
Agent and each Bank on an after-tax basis (computed taking into account any
deductions or other benefits available for federal income tax purposes for the
Agent or such Bank if it is a United States taxpayer and any deductions and
benefits available for income tax purposes in any jurisdiction in which the
Agent or such Bank is a taxpayer) on demand for, any and all Taxes paid or
incurred by the Agent or such Bank in connection with the transactions
contemplated by this Agreement; PROVIDED, HOWEVER, that the foregoing indemnity
does not cover Excluded Taxes. Reimbursement on an "after-tax basis" means on a
basis such that the Agent or such Bank is made whole after taking into account
income taxes that the Agent or such Bank will owe on the indemnity or
reimbursement payment in any jurisdiction and any related tax benefits, assuming
the Agent or such Bank is subject to income taxes at the highest marginal rates.
Nothing in this paragraph shall interfere with the right of the Agent or any
Bank to arrange its tax affairs in whatever manner it thinks fit and, in
particular, the Agent and the Banks are under no obligation to claim a deduction
or other benefit relating to these transactions ahead of any other claim,
relief, credit, deduction or other benefit to which it is entitled. The Agent,
or applicable Bank through the Agent, shall promptly give written notice to the
Company after (but in no event later than 60 days after) the Agent or such Bank
has actual knowledge of the imposition of any Taxes subject to indemnification
hereunder; PROVIDED, HOWEVER, that failure to give such notice within such 60
day period will not relieve the Company of the obligation to indemnify the Agent
or such Bank in accordance with the terms hereof, except to the extent of
interest that would have been avoided had the notice been given prior to the end
of such 60-day period.

     (c) The Company will provide evidence that all Taxes imposed on payments
under this Agreement, any PPA LOC Loan or the PPA LOC Loan Note, have been fully
paid to the appropriate authorities by delivering official receipts or notarized
copies to the Agent within 30 days after payment. The Company will compensate
the Agent or any Bank that has to pay any Taxes because the Company failed to
timely furnish such evidence; PROVIDED, that prior to paying such Taxes, the
Agent, or such Bank through the Agent, shall have notified the Company of its
intent to make such payment.

     (d) If the Company so requests promptly in writing after receipt of any
notice under Section 2.17 hereof, the Agent or applicable Bank will contest in
good faith the Taxes at the Company's expense, keep the Company fully informed
about the progress of the contest, consult in good faith with the Company's
counsel regarding conduct of the contest, and not compromise or otherwise settle
the contest without the Company's consent (which shall not be unreasonably
withheld or delayed); PROVIDED, that the Agent or such Bank may in its sole
discretion select the forum for the contest and determine whether the contest
will be by resisting payment of the


                                       16
<PAGE>

Taxes or by paying the Taxes and seeking a refund; PROVIDED, FURTHER that the
Agent or such Bank will be under no obligation to contest unless (A) if the
Agent or such Bank requests, the Company has provided the Agent or such Bank an
opinion of independent tax counsel selected by the Company and reasonably
acceptable to the Agent or such Bank to the effect that there is a reasonable
basis for the contest, (B) the amount in controversy is at least $75,000, (C)
the Agent or such Bank has received satisfactory indemnification and security
for any liability, loss, cost or expense arising out of the contest (including,
but not limited to, all reasonable legal and accounting fees and expenses,
penalties, interest and additions to tax), (D) if requested by the Agent or such
Bank, the Company has admitted in writing its duty to indemnify the Agent or
such Bank for the Taxes if the contest is lost (but such admission shall not
preclude the Company from raising a defense to liability if a court of competent
jurisdiction has rendered a decision articulating the cause of such Taxes, and
the cause is not one for which the Company is responsible under this Section
2.17), and (E) if the contest is conducted in a manner that requires paying all
or part of the Taxes, the Company has paid the amount required.

     (e) If the Company so requests within 10 days of notice to the Company of
the imposition of any Taxes on payments to any of the Banks of a type not
generally imposed on United States or foreign lenders making advances of the
types contemplated hereunder, such Banks shall (consistent with legal and
regulatory restrictions) comply with Section 2.19 hereof.

     (f) At such times as may be required by Applicable Law or as the Agent or
the Company may reasonably request, each Bank agrees that it will deliver to the
Agent and the Company duly completed forms of any applicable jurisdiction or
other documentation reasonably satisfactory to the Agent and the Company that
such Bank is entitled to receive payments under this Agreement without deduction
or withholding of income tax under the Applicable Law of such jurisdiction. Each
Bank further agrees to notify the Agent and the Company of the occurrence of any
event (including any change in treaty, law or regulation) that would render such
Bank unable to receive payments hereunder without such deduction or withholding.
The provisions of this Section 2.17(f) shall apply to any successor holder of a
PPA LOC Loan Note.

     SECTION 2.18 ILLEGALITY.

     If, on or after the date of this Agreement, the adoption of any Applicable
Law, or any change therein, or any change in the interpretation or
administration thereof by any Governmental Authority, central bank or comparable
agency charged with the interpretation or administration thereof, or compliance
by the Agent or any Bank with any request or directive (whether or not having
the force of law) of any such Governmental Authority, central bank or comparable
agency shall make it unlawful or impossible for the Agent or such Bank to make,
continue or convert its Eurodollar Rate Loans, the Agent, or such Bank through
the Agent, shall so notify the Company, whereupon until the Agent, or such Bank
through the Agent, notifies the Company that the circumstances giving rise to
such suspension no longer exist, the obligation of the Agent or such Bank to
make or continue Eurodollar Rate Loans, or to convert outstanding PPA LOC Loans
into Eurodollar Rate Loans, shall be suspended. Before giving any notice to the
Company pursuant to this Section 2.18, the Agent or applicable Bank shall
designate a different lending office for the Eurodollar Rate Loans if such
designation will avoid the need for giving such notice and will not, in the sole
judgment of the Agent or such Bank, be otherwise


                                       17
<PAGE>

disadvantageous to the Agent or such Bank. If such notice is given, each
Eurodollar Rate Loan of the Agent or such Bank then outstanding shall either (i)
be converted to a Base Rate Loan on the last day of the then current Interest
Period applicable to such Eurodollar Rate Loan if the Agent or such Bank may
lawfully continue to make and continue such PPA LOC Loan to such day, or (ii) be
immediately converted to a Base Rate Loan if the Agent or such Bank shall
determine that it may not lawfully continue to make and continue such PPA LOC
Loan to such day; PROVIDED, that the Company shall not be obligated to make any
payment pursuant to Section 2.6(c) as a result of such conversion. If the
Company so requests within 10 days of receipt of the notice referred to above,
the applicable Bank shall (consistent with legal and regulatory restrictions)
comply with Section 2.19 hereof.

     SECTION 2.19 ASSIGNMENTS BY BANKS.

     (a) If at least 180 days before the Expiration Date, the Agent shall have
requested the consent of each of the other Banks to the extension of the PPA
Letter of Credit, and if the Agent shall not, within twenty-five (25) days of
issuing such request, have received the written consent of any Bank to the
extension proposed by the Agent, the Agent shall have the right to require such
Bank to transfer all of its proportionate share of the PPA LOC Loans in
accordance with Section 2.19(b). Prior to the Notice Date, each Bank shall give
the Agent written notice of such Bank's election to extend or not to extend the
original or extended Expiration Date of the PPA Letter of Credit for an
additional one or more years as specified by the Agent.

     (b) In the event that (i) a Bank is required to comply with this Section
2.19 after a request from the Company pursuant to Sections 2.17 or 2.18, (ii)
the Company or the Issuing Bank requests that the provisions of this Section
2.19 apply to a Bank within 10 days after the Company receives a notice from the
Agent that (a) such Bank has failed to make available to the Agent its portion
of any PPA LOC Loan on the date required to be made available to the Agent
pursuant to this Agreement after the Agent has made written demand upon such
Bank for such payment, (b) such Bank has provided the Agent with notice that
such Bank shall not make available to the Agent such portion of any PPA LOC Loan
required to be made available to the Agent pursuant to this Agreement or (c)
such Bank has failed to reimburse the Agent pursuant to the terms of this
Agreement, or (iii) the Issuing Bank requests that the provisions of this
Section 2.19 apply to a Bank in the event the long-term debt rating of such Bank
shall at any time be less than a rating of "A" or the equivalent by S&P or by
Moody's, then such Bank shall assign all or a part of its proportionate share of
the PPA LOC Loans and its Commitment to a replacement bank (which may be, but is
not required to be, a Bank, and shall be subject to the prior written consent of
the Issuing Bank) (a "REPLACEMENT BANK") designated by the Company; PROVIDED,
that any assignment or transfer made by a Bank to a Replacement Bank shall
substantially be in the form of Exhibit C hereto, and any assignment of all or
part of the PPA LOC Loans or other obligations with respect to the PPA Letter of
Credit shall be made without recourse, representation or warranty. The Company
shall promptly pay when due all reasonable fees and expenses which such Bank
incurs in connection with such transfer or assignment and the Company shall
cause the Replacement Bank to pay to the Agent for the account of the assigning
Bank in immediately available funds all amounts outstanding or payable under
this Agreement to each Bank assigning its interest in the PPA LOC Loans or other
obligations with respect to the PPA Letter of Credit.

     SECTION 2.20 REDUCTION IN COMMITMENTS/REIMBURSEMENTS.

     The Company shall have the right to refinance the Commitment and any
outstanding PPA LOC Loans, if any, without premium or penalty, except as
provided in Section 2.6(c), upon at least 10 Business Days' prior written notice
to the Agent.

     SECTION 2.21 RIGHT OF SET-OFF.

     Subject to the provisions of the Collateral Agency Agreement, the Company
hereby authorizes each Bank (in addition to, and without limitation of, any
right of set-off, banker's lien or counterclaim a Bank may otherwise have), upon
the occurrence and during the continuance of any Event of Default, at any time
and from time to time, without notice to the Company or any Person other than
the Collateral Agent (any such notice being hereby expressly waived by the
Company to the extent it may legally do so) to set off and appropriate and apply
any and all deposits (general or special, time or demand, provisional or final)
at any time held, and other indebtedness at any time owing, by such Bank in any
of its offices, wherever located (whether such deposits or indebtedness be in
Dollars or in any other currency), to or for the credit or the account of the
Company against any and all of the Obligations and liabilities of the Company
now or hereafter existing under this Agreement, irrespective of whether or not
such Bank shall have made any demand hereunder or thereunder and although such
Obligations may be contingent or unmatured.

                                   ARTICLE III

     with any suit, action or proceeding relating to such documents in the

presented for payment.

                         REPRESENTATIONS AND WARRANTIES

     SECTION 4.1 REPRESENTATIONS AND WARRANTIES OF COMPANY.

<PAGE>

     (d) This Agreement has been, and, upon issuance thereof, the PPA Letter of
Credit will have been, duly executed and delivered by the Issuing Bank.

     (e) This Agreement constitutes, and the PPA Letter of Credit upon issuance
thereof will constitute, legal, valid and binding obligations of the Issuing
Bank, enforceable against it in accordance with the respective terms thereof,
except as such enforceability (i) may be limited by applicable bankruptcy,

enforcement of creditors' rights and remedies generally and (ii) is subject to
general principles of equity (regardless of whether enforceability is considered
in a proceeding in equity or at law).

                                   ARTICLE V

                                    COVENANTS

     SECTION 5.1 COVENANTS.

     So long as any Commitment is in effect, the PPA Letter of Credit is
outstanding or the Obligations remain unpaid, the Company shall observe and
perform all of the covenants of the Company contained in Article VI of the
Indenture (which covenants are incorporated herein by reference as if fully set
forth herein).

                                   ARTICLE VI

                              DEFAULTS AND REMEDIES

     SECTION 6.1 EVENTS OF DEFAULT.

     Each of the following shall constitute an "Event of Default" under this
Agreement so long as the same shall be continuing:

     (a) the Company shall fail to pay any amount due under this Agreement
(including under the PPA LOC Loan Note) within 15 days after the due date
thereof; or

     (b) an "Event of Default" under the Indenture shall have occurred and be
continuing; or

     (c) an "Event of Default" under the DSR LOC Reimbursement Agreement shall
have occurred and be continuing; or

     (d) an "Event of Default" under the Working Capital Agreement shall have
occurred and be continuing.

     SECTION 6.2 REMEDIES.

     Upon the occurrence and during the continuation of an Event of Default, the
Agent shall, at the request of the Required Banks, take one or more of the
following actions: (i) terminate the


                                       21
<PAGE>

PPA Letter of Credit in accordance with the terms thereof, (ii) declare the
Obligations, all interest thereon and all other amounts payable under this
Agreement and the PPA LOC Loan Note to be forthwith due and payable, including
but not limited to the amount of any and all PPA LOC Loans which may be made
upon a Drawing under the PPA Letter of Credit which occurs after the date on
which the Agent declares such amounts to be due and payable, but prior to the
effective date of termination of such PPA Letter of Credit in accordance with
Section 2.2(b), whereupon the Obligations, all such interest and all such
amounts shall become and be forthwith due and payable, without presentment,
demand, protest or further notice of any kind, all of which are hereby expressly
waived by the Company or (iii) terminate the ability of the Company to continue
PPA LOC Loans as, or to convert PPA LOC Loans to, Eurodollar Rate Loans;
PROVIDED, that the Agent and the Banks shall not have the right to exercise any
other remedy hereunder or otherwise available to the Agent or any Bank except in
accordance with the provisions of the Collateral Agency Agreement.

     SECTION 6.3 COLLATERALIZATION UPON ACCELERATION OF THE BONDS.

     In the event that an Event of Default hereunder results from an "EVENT OF
DEFAULT" under the Indenture and the Trustee accelerates amounts due under the
Indenture, the PPA LOC Provider shall be entitled to require collateralization
of the Stated Amount by having the Collateral Agent deposit (in a separate
account to be held by the Collateral Agent), at the time that any amounts are
paid to the Trustee in respect of accelerated amounts due under the Indenture,
an amount equal to the amount that would have been disbursed to the Agent at
such time (based on pro rata payment requirements) if Drawings had been made to
the full extent of the Stated Amount ("DEEMED PPA LOC LOANS") and the Deemed PPA
LOC Loans had been accelerated at the same time as an acceleration under the
Indenture. Upon a Drawing on the PPA Letter of Credit, a portion of the amount
in the separate account equal to such Drawing's proportionate share of the
Stated Amount shall be transferred by the Collateral Agent to the PPA LOC
Provider. The Agent, the Issuing Bank and each Bank agree that upon termination
or expiration of the PPA Letter of Credit, all amounts in such separate
collateral account that have not been transferred pursuant to the previous
sentence (to the extent of such expiration or termination) shall be transferred
to the Collateral Agent.

                                  ARTICLE VII

                            CHARACTER OF OBLIGATIONS

     SECTION 7.1 OBLIGATIONS ABSOLUTE.

     The Obligations shall be absolute, unconditional and irrevocable and shall
not be affected or impaired under any circumstances whatsoever, including the
following circumstances:

     (a) any lack of validity or enforceability of any provision of any Project
Contract or Financing Document;

     (b) any amendment or waiver of, or any consent to departure from, any
provision of any Project Contract or Financing Document;


                                       22
<PAGE>

     (c) the existence of any claim, set-off, defense or other right that the
Company may have at any time against the beneficiary of the PPA Letter of Credit
(or any Person for whom such beneficiary may be acting), any Bank, the Agent or
any other Person, whether in connection with any Project Contract or Financing
Document, the transactions contemplated thereby or any unrelated transaction;

     (d) any statement or signature in any certificate or other document
presented under the PPA Letter of Credit proving to be forged, fraudulent,
invalid or insufficient in any respect, or any such statement being untrue or
inaccurate in any respect whatsoever;

     (e) any exchange, release or nonperfection of any Collateral or other
collateral, or any release, amendment or waiver of or consent to departure from
any Project Contract, Financing Document or any guaranty, for any of the
Obligations;

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

     (g) any other circumstance or happening whatsoever, whether or not similar
to any of the foregoing.

     SECTION 7.2 LIMITED LIABILITY OF AGENT AND BANKS.

     As among the Company, the Agent and the Banks (including the Issuing Bank),
the Company assumes all risks of the acts or omissions of the beneficiaries of
the PPA Letter of Credit with respect to the use of the PPA Letter of Credit.
Neither the Agent nor any Bank nor any of their respective officers, directors,
employees or agents shall be liable or responsible for (i) the use that may be
made of the PPA Letter of Credit or any acts or omissions of any beneficiaries
of the PPA Letter of Credit in connection with the PPA Letter of Credit; (ii)
the form, validity, sufficiency, accuracy, genuineness or legal effect of any
document submitted in connection with the PPA Letter of Credit or of any
endorsement thereon, even if such document or endorsement should prove to be in
any or all respects invalid, insufficient, inaccurate, fraudulent or forged;
(iii) payment by the Issuing Bank against presentation of any document that does
not comply with the terms of the PPA Letter of Credit, including failure of any
document to bear any reference or adequate reference to the PPA Letter of
Credit; or (iv) any other circumstance whatsoever in making, delaying to make or
failing to make payment under the PPA Letter of Credit; PROVIDED, HOWEVER, that
the Company shall have a claim against the Issuing Bank, and the Issuing Bank
shall be liable to the Company, to the extent of any direct, as opposed to
consequential, damages suffered by the Company that the Company proves were the
result of the Issuing Bank's willful misconduct or gross negligence in paying
under the PPA Letter of Credit or the Issuing Bank's willful or grossly
negligent failure to pay under the PPA Letter of Credit after the presentation
to it by the beneficiary of a draft and certificate strictly complying with the
terms and conditions of the PPA Letter of Credit (unless the Issuing Bank in
good faith believed itself (based upon an opinion of counsel) to be prohibited
by law or legal authority from making such payment). In furtherance and not in
limitation of the foregoing, the Issuing Bank may accept any document that
appears on its face to be in order, without responsibility for further
investigation, regardless of any notice or information to the contrary.

                                  ARTICLE VIII

                                    THE AGENT

     SECTION 8.1 AUTHORIZATION AND ACTION.

     (a) Each Bank hereby appoints and authorizes the Agent to take such action
as agent on its behalf and to exercise such powers under this Agreement as are
delegated to the Agent by the terms hereof, together with such powers as are
reasonably incidental thereto. As to any matters not expressly provided for by
the Credit Documents (including enforcement of and collection under any Credit
Document or other Project Contract), the Agent shall not be required to exercise
any discretion or take any action, but shall be required to act or to refrain
from acting (and shall be fully protected in so acting or refraining from
acting) upon the instructions of the Required Banks, and such instructions shall
be binding upon all Banks and the holders of any PPA LOC Loan Note; PROVIDED,
HOWEVER, that the Agent shall not be required to take any action that, in the
Agent's sole judgment, exposes the Agent to personal liability or that is
contrary to any Credit Document or other Project Contract or Applicable Law. In
performing its function and duties hereunder as Agent, the Agent shall act
solely as the agent of the Banks and in its capacity as Issuing Bank it shall
act solely as issuer of the PPA LOC Letter of Credit, and does not assume and
shall not be deemed to have assumed in either such capacity any obligation
towards or relationship of agency or trust or other fiduciary relationship with
or for the Company or any other party to any Project Contract.

     (b) Each Bank hereby authorizes the Agent in the name of and on behalf of
such Bank to sign such documents, take all such actions and perform such
obligations that the Agent deems necessary or appropriate to bind each of the
Banks under the Credit Documents and the Transaction Documents, and to create,
perfect or maintain the existence or perfected status of any security interest,
to be the named "Senior Party" under the Collateral Agency Agreement, and the
sole named payee, in respect of all of the Financing Liabilities of the Company
under or pursuant to this Agreement and the PPA LOC Loan Note, and all
Collateral to the extent securing such Financing Liabilities, and to take all
such actions and perform such obligations that the Agent deems necessary or
appropriate in such capacity.

     SECTION 8.2 AGENT'S RELIANCE, ETC.

     Neither the Agent nor the Issuing Bank nor any of their directors,
officers, agents or employees shall be liable for any action taken or omitted to
be taken by it or them under or in connection with any Credit Document or other
Project Contract, except for its or their own gross negligence or willful
misconduct. Without limitation of the generality of the foregoing, the Agent and
the Issuing Bank (i) may treat any Bank that has signed an Assignment and
Acceptance as the holder of the applicable portion of the Obligations; (ii) may
consult with legal counsel (including counsel for the Company or any Affiliate),
independent public accountants and other experts selected by it and shall not be
liable for any action taken or omitted to be taken in good faith by it in
accordance with the advice of such counsel, accountants or experts; (iii) makes
no warranty or representation to any Bank and shall not be responsible to any
Bank for any statements, warranties or representations made in or in connection
with any Credit


                                       24
<PAGE>

Document or other Project Contract; (iv) shall not have any duty to ascertain or
to inquire as to the performance or observance of any of the terms, covenants or
conditions of any Credit Document or other Project Contract on the part of the
Company or any Affiliate or to inspect the property (including the books and
records) of the Company or any Affiliate thereof; (v) shall not be responsible
to any Bank for the due execution, legality, validity, enforceability,
genuineness, sufficiency or value of any Credit Document or other Project
Contract or any other instrument or document furnished pursuant hereto or
thereto; and (vi) shall incur no liability under or in respect of any Credit
Document or other Project Contract by acting upon any notice, consent,
certificate or other instrument or writing (which may be by telecopier or
otherwise) believed by it to be genuine and signed or sent by the proper party
or parties.

     SECTION 8.3 THE AGENT, THE ISSUING BANK AND AFFILIATES.

     With respect to its Commitment and participation in the PPA Letter of
Credit, the Agent and the Issuing Bank shall have the same rights and powers
under this Agreement as any other Bank and may exercise the same as though it
were not the Agent or the Issuing Bank, as the case may be; and the term "BANK"
or "BANKS" shall, unless otherwise expressly indicated, include the Agent and
Issuing Bank in their capacity as a Bank (including the Issuing Bank in its
capacity as such). The Agent and the Issuing Bank and their Affiliates may
accept deposits from, lend money to, act as trustee under indentures of, and
generally engage in any kind of business with, the Company, any Affiliate
thereof and any Person that may do business with or own securities of the
Company or any Affiliate thereof, all as if the Agent and the Issuing Bank,
respectively, were not the Agent and the Issuing Bank, and without any duty to
account therefor to the Banks.

     SECTION 8.4 BANK CREDIT DECISION.

     Each Bank agrees that it has, independently and without reliance on the
Agent, the Issuing Bank or any other Bank 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 also agrees that it will,
independently and without reliance on the Agent, the Issuing Bank or any other
Bank and based on such documents and information as it deems appropriate at the
time, continue to make its own credit decisions in taking or not taking action
under this Agreement.

     SECTION 8.5 INDEMNIFICATION.

     Each of the Banks agree to indemnify the Agent and the Issuing Bank (to the
extent not promptly reimbursed by the Company and without limiting the
obligation of the Company to do so), on demand, ratably according to such Bank's
Percentage Interest, from and against any and all liabilities, obligations,
losses, damages, penalties, actions, judgments, suits, costs, expenses and
disbursements of any kind or nature whatsoever that may at any time (including
at any time following the payment of any Obligations or termination of this
Agreement) be imposed on, incurred by or asserted against the Agent or the
Issuing Bank in any way relating to or arising out of any Credit Document or
other Project Contract or any action taken or omitted by the Agent under any
Credit Document or other Project Contract; PROVIDED, HOWEVER, that no Bank shall
be liable for any portion of such liabilities, obligations, losses, damages,
penalties, actions, judgments, suits, costs, expenses or disbursements to the
extent resulting solely from the Agent's gross negligence or willful misconduct.
Without limitation of the foregoing, each Bank agrees to



                                       25
<PAGE>

reimburse the Agent promptly upon demand for its ratable share of any costs and
expenses payable by the Company under Section 9.4, to the extent that the Agent
is not reimbursed for such costs and expenses by the Company.

     SECTION 8.6 SUCCESSOR AGENT.

     The Agent may resign at any time by giving written notice thereof to the
Banks and the Company and may be removed at any time with or without cause with
the written approval of the Required Banks. Upon any such resignation or
removal, the Required Banks shall have the right to appoint a successor Agent
with the consent of the Company, which shall not be unreasonably withheld or
delayed. If no successor Agent has been so appointed by the Required Banks, and
has accepted such appointment, within 30 days after the retiring Agent's giving
of notice of resignation or the Required Banks' removal of the retiring Agent,
then the retiring Agent may, on behalf of the Banks, appoint a successor Agent
with the consent of the Company (which shall not be unreasonably withheld or
delayed), which successor Agent shall be a commercial bank organized under the
laws of the United States of America or of any state thereof and having a
combined capital and surplus of at least $500,000,000. Upon the acceptance of

LOC Loan Note, the other Credit Documents and the other documents to be

     SECTION 9.6 SEVERABILITY.

     Any provision of this Agreement that is prohibited, unenforceable or not
authorized in any jurisdiction shall, as to such jurisdiction, be ineffective to
the extent of such prohibition, unenforceability or nonauthorization without

validity, enforceability or authorization of such provision in any other
jurisdiction.

     SECTION 9.7 NON-RECOURSE LIABILITY.

     Satisfaction of the Obligations shall be had solely from the Collateral.
Notwithstanding any provision to the contrary in the Transaction Documents,
there shall be no recourse against any Affiliates, stockholders, officers,
directors, representatives or employees of the Company, other than the Company
(each a "NON-RECOURSE PARTY"), for any payment due hereunder or under any other
Financing Document or Security Document from the Company or for the performance
of any obligation of such Non-Recourse Party, or breach of any representation or
warranty made by such Non-Recourse Party hereunder or thereunder. The sole
recourse of the Agent and the Banks hereunder or under any other Transaction
Document or for the performance of any obligation of the Company, or breach of
any representation or warranty made hereunder or thereunder by the Company,
shall be against the Company and its assets, it being expressly understood by
the Senior Parties that such obligations are obligations solely of the Company
and


                                       28
<PAGE>

that no such personal liability shall attach to, or be incurred by any
Non-Recourse Party; PROVIDED, that nothing contained in this Section 9.7 shall
(i) impair in respect of the Company the validity of any PPA LOC Loan Note, or
any other Credit Documents, as applicable, prevent the taking of any action
permitted by law against the Company or any of its Affiliates, or in any way
affect or impair the rights of the Agent and the Banks to take any action
permitted by law, in either case to realize upon the Collateral, (ii) be deemed
to release the Company or any of its Affiliates, or any past, present or future
shareholder, partner, officer, employee, director or agent of any thereof, from
liability for its fraudulent actions, fraudulent misrepresentations, gross
negligence or willful misconduct or (iii) limit or affect the obligations and
liabilities of any Non-Recourse Party in accordance with the terms of any other
Transaction Document creating such obligations and liabilities to which such
Non-Recourse Party is a party.

     SECTION 9.8 BINDING EFFECT.

     This Agreement shall be binding upon and inure to the benefit of the
Company, the Agent and the Banks and their respective successors and assigns,
except that the Company shall not have the right to assign any of its rights and
obligations hereunder without the prior written consent of the Required Banks,
and, except as provided in Section 9.9, no Bank other than the Issuing Bank
shall have the right to assign any of its rights and obligations hereunder.

     SECTION 9.9 ASSIGNMENTS AND PARTICIPATIONS.

     (a) Any Bank may at any time (with the consent of the Company, such consent
not to be unreasonably withheld or delayed, the consent of the Agent, such
consent not to be unreasonably withheld or delayed, and the consent of the
Issuing Bank) sell to one or more banks or other entities whose long-term
unsecured debt is rated at least "A" or the equivalent by S&P and Moody's (a
"PURCHASING BANK") all or any part of its rights and obligations under this
Agreement and the PPA LOC Loan Note (which, except in the case of an assignment
to a Person that, immediately before such assignment, was a Bank, shall be in an
amount equal to not less than the lesser of (x) $5,000,000 and (y) 25% of the
Stated Amount pursuant to an Assignment and Acceptance, executed by such
Purchasing Bank, such transferor Bank, the Agent and the Issuing Bank (and, in
the case of a Purchasing Bank that is not then a Bank or an Affiliate thereof,
by the Company). Upon (i) such execution of such Assignment and Acceptance and
(ii) delivery of a copy thereof to the Company and payment of the amount of its
participation to the Agent or such transferor Bank, such Purchasing Bank shall
for all purposes be a Bank party to this Agreement and shall have all the rights
and obligations of a Bank under this Agreement, to the same extent as if it were
an original party hereto with the Percentage Interest as set forth in such
Assignment and Acceptance, which shall be deemed to amend this Agreement to the
extent, and only to the extent, necessary to reflect the addition of such
Purchasing Bank and the resulting adjustment of Percentage Interests arising
from the purchase by such Purchasing Bank of all or a portion of the rights and
obligations of such transferor Bank under this Agreement and the PPA LOC Loan
Note.

     (b) Any Bank may, from time to time, sell or offer to sell participating
interests in any PPA LOC Loans owing to such Bank, such Bank's interest in any
PPA LOC Loan Note, any Commitment of such Bank or any other interests and
obligations of such Bank hereunder, to one or more banks or other entities
(each, a "PARTICIPANT"), on such terms and conditions as may be


                                       29
<PAGE>

determined by the selling Bank, without the consent of or notice to the Company,
and the grant of such participation shall not relieve any Bank of its
obligations, or impair the rights of any Bank, hereunder. In the event of any
such sale by a Bank of a participating interest to a Participant, such Bank
shall remain solely responsible for the performance of such Bank's obligations
under this Agreement, the Company, the Agent and the Issuing Bank will continue
to deal solely and directly with such Bank in connection with such Bank's rights
and obligations under this Agreement and such Bank shall retain the sole right
and responsibility to exercise the rights of such Bank, and enforce the
obligations of the Company, including the right to approve any amendment,
modification, supplement or waiver of any provision of any Credit Document and
the right to take action under Article 6 hereof and such Bank shall not grant
any such Participant any voting rights or veto power over any such action by
such Bank under this Agreement (PROVIDED, that such Bank may agree not to
consent to any modification, amendment or waiver of this Agreement, without the
consent of the Participant, that would alter the principal of or interest on any
PPA LOC Loans, postpone the date fixed for any payment of principal of or
interest thereon or extend the term of any Commitment). No Participant shall
have any rights under this Agreement to receive payment of principal, interest
or any other amount payable hereunder except through a Bank and as provided in
this Section 9.9. The Company agrees that, upon the occurrence and during the
continuance of any Event of Default, each Participant shall have the right of
set-off in respect of its participating interest in amounts owing under this
Agreement and any PPA LOC Loan Note as set forth in Section 2.21 hereof to the
same extent as if the amount of its participating interest was owing directly to
it as a Bank under this Agreement or any PPA LOC Loan Note. The Company also
agrees that each Participant shall be entitled to the benefits of Sections 2.15,
2.16, 2.17 and 2.18 hereof with respect to its participation granted hereunder;
PROVIDED, that no Participant shall be entitled to receive any greater amount
pursuant to such Sections than the Bank transferring such participation would
have been entitled to receive in respect of the amount of the participation
transferred to such Participant had no such transfer occurred.

     (c) Any Bank may, in connection with any assignment or participation or
proposed assignment or participation pursuant to this Section 9.9, disclose to
the Purchasing Bank or Participant or proposed Purchasing Bank or Participant
any information relating to the Company furnished to such Bank by or on behalf
of the Company; PROVIDED, HOWEVER, that prior to any such disclosure, the Person
receiving such disclosure shall sign such confidentiality agreements as the
Company may reasonably request.

     SECTION 9.10 INDEMNIFICATION.

     The Company agrees to indemnify, on demand, and hold harmless the Agent and
each Bank (including the Issuing Bank) and each of their respective officers,
directors, employees, agents and affiliates from and against any and all claims,
damages, losses, liabilities, costs and expenses whatsoever that such
indemnified party may incur (or that may be claimed against such indemnified
party by any Person) by reason of (i) any untrue statement or alleged untrue
statement of any material fact concerning the Company or the Collateral, or the
omission or alleged omission to state any fact concerning the Company or the
Collateral necessary to make any such statement, in light of the circumstances
under which it was made, not misleading; (ii) the issuance, sale or delivery of
the Senior Debt; (iii) the use of the proceeds of the Senior Debt or any
Drawing; (iv) any reasonable action taken by such indemnified party in
protecting


                                       30
<PAGE>

and enforcing the rights and remedies of the Agent and the Banks under the
Project Contracts; (v) subject to Section 7.2, the execution, delivery or
transfer of, or payment or failure to pay under, the PPA Letter of Credit; (vi)
any claim of any Person with respect to any finder's fee, brokerage commission
or other similar sum due in connection with any Project Contract; or (vii) any
failure by the Company to comply with any Environmental Requirement; PROVIDED,
HOWEVER, that the Company shall not be required to indemnify the Issuing Bank
for any claims, damages, losses, liabilities, costs or expenses to the extent
caused by the Issuing Bank's willful misconduct or gross negligence in paying
under the PPA Letter of Credit or the Issuing Bank's willful or grossly
negligent failure to pay under the PPA Letter of Credit after the presentation
to it by the beneficiary of a draft and certificate strictly complying with the
terms and conditions of the PPA Letter of Credit (unless the Issuing Bank in
good faith believed itself (based upon an opinion of counsel) to be prohibited
by law or legal authority from making such payment). The Company, upon demand by
any party indemnified or intended to be indemnified pursuant to this Section
9.10 at any time, shall also reimburse such party for any reasonable legal or
other expenses incurred in connection with investigating or defending against
any of the foregoing. If any action, suit or proceeding arising from any of the
foregoing is brought against any party indemnified or intended to be indemnified
pursuant to this Section 9.10 (an "INDEMNIFIED PARTY"), such Indemnified Party
shall promptly notify the Company in writing, enclosing a copy of all papers
served, but the omission so to notify the Company of any such action shall not
relieve it of any liability that it may have to any Indemnified Party otherwise
than under this Section 9.10; PROVIDED, HOWEVER, that the Company shall not be
liable for any settlement of any such action effected without the Company's
prior written consent. In case any such action shall be brought against any
Indemnified Party and it shall notify the Company of the commencement thereof,
the Company shall be entitled to participate in and, to the extent that it shall
wish, to assume the defense thereof with counsel reasonably satisfactory to such
Indemnified Party, and after notice from the Company to such Indemnified Party
of the Company's election so to assume the defense thereof, the Company shall
not be liable to such Indemnified Party for any subsequent legal or other
expenses attributable to such defense, except as provided below, other than
reasonable costs of investigation subsequently incurred by such Indemnified
Party in connection with the defense thereof. The Indemnified Party shall have
the right to employ its own counsel in any such action, but the fees and
expenses of such counsel shall be at the expense of such Indemnified Party
unless (i) the employment of counsel by such Indemnified Party has been
authorized by the Company, (ii) the Indemnified Party shall have reasonably
concluded that there may be a conflict of interest between the Company and the
Indemnified Party in the conduct of the defense of such action (in which case
the Company shall not have the right to direct the defense of such action on
behalf of the Indemnified Party) or counsel for the Company shall have declined
to represent the Indemnified Party in light of a potential conflict of interest
or (iii) the Company shall not in fact have employed counsel reasonably
satisfactory to the Indemnified Party to assume the defense of such action.

FOR VALUE RECEIVED, the undersigned, AES Red Oak, L.L.C., a Delaware limited
liability company (the "COMPANY"), hereby unconditionally promises to pay to the
order of Dresdner Bank AG, acting through its New York Branch (the "AGENT") for
the benefit of the Banks party from time to time to the Reimbursement Agreement
referred to below the lesser of (i) the principal sum of Thirty Million Dollars
($30,000,000.00) and (ii) the aggregate unpaid principal amount of the PPA LOC
Loans owing to the Banks by the Company under the Reimbursement Agreement, on
the dates and in the amounts specified therein.

The Company further promises to pay interest on the daily unpaid principal
amount hereof from time to time outstanding on the dates and at the rates
specified in the Reimbursement Agreement. This PPA LOC Loan Note is hereby
expressly limited so that in no contingency or event, whether by reason of
acceleration of the maturity of any indebtedness evidenced hereby or otherwise,
shall the interest contracted for or charged or received by the Agent for the
account of the Banks exceed the maximum amount permissible under Applicable Law.
If, from any circumstance whatsoever, interest would otherwise be payable to the
Agent for the account of the Banks in excess of the maximum lawful amount, the
interest payable to the Agent for the account of the Banks shall be reduced to
the maximum amount permitted under Applicable Law, and the amount of interest
for any subsequent period, to the extent less than that permitted by Applicable
Law, shall to that extent be increased by the amount of such reduction.

The holder hereof is irrevocably authorized to endorse on the schedule attached
hereto, or on a continuation thereof, the date each such interest payment is due
and the amount of each such interest payment determined in accordance with the
Reimbursement Agreement. All such notations shall constitute PRIMA FACIE
evidence of the accuracy of the information so recorded and be enforceable
against the Company with the same force and effect as if such amounts were each
set forth in a separate PPA LOC Loan Note executed by the Company.

All payments due hereunder shall be made without set-off, counterclaim or
deduction of any nature to the Agent, for the account of the Banks, in lawful
money of the United States of America and in immediately available funds, at
such place and in such manner as may be specified by the Agent pursuant to the
Reimbursement Agreement.

The holder hereof is irrevocably authorized to endorse on the schedule attached
hereto, or on a continuation thereof, the date and amount of each PPA LOC Loan
incurred by the Company and each payment or prepayment of principal thereof,
provided that the failure of the holder to make, or any error in making, any
such recordation or endorsement shall not affect the obligations of the Company
hereunder or under the Reimbursement Agreement. All such notations shall
constitute PRIMA FACIE evidence of the accuracy of the information so recorded
and be

for the benefit of the Banks, referred to in, evidences each PPA LOC Loan owing
to the Banks by the Company under, is subject to the provisions of, and entitles
the holder to the benefits of, the Power Purchase Agreement Letter of Credit and
Reimbursement Agreement, dated as of March 1, 2000 (the "REIMBURSEMENT

thereto, and the Agent, as the same may be amended, supplemented or otherwise
modified from time to time and to which reference is hereby made for a more
complete statement of the terms and conditions under which each PPA LOC Loan
evidenced hereby is to be incurred and paid. Capitalized terms in this PPA LOC
Loan Note that are not specifically defined herein shall have the meanings
ascribed to them in the Reimbursement Agreement.

The Reimbursement Agreement provides for, among other things, the acceleration
of the maturity of the unpaid principal amount hereof upon the occurrence of
certain stated events and for voluntary prepayments in certain circumstances and
upon certain terms and conditions. The obligations of the Company under the
Reimbursement Agreement and this PPA LOC Loan Note are secured by, and the
holder hereof is entitled to the benefit of, the Security Documents.

In addition to any and all costs, fees and expenses for which the Company is
liable under the Reimbursement Agreement, the Company promises to pay all costs
and expenses, including reasonable attorneys' fees and disbursements, incurred
in the collection and enforcement hereof or any appeal of any judgment rendered
hereon.

The Company hereby expressly waives diligence, presentment, protest, demand,
dishonor, nonpayment and notice of every kind to the fullest extent permitted by
Applicable Law. No failure or delay by the holder of this PPA LOC Loan Note to
exercise any right or remedy under this PPA LOC Loan Note or any other document
or instrument entered into pursuant to the Reimbursement Agreement shall operate
or be construed as a waiver or modification hereof or thereof.

Company and shall inure to the Agent and its successors, endorsees and assigns.

illegal or unenforceable, the validity of all other terms and provisions hereof
shall in no way be affected thereby.
