        (c) If a Term Conversion Event shall have occurred, and the Agent,
subject to the approval of the Required Banks, elects to convert any PPA LOC
Loan into a PPA Term Loan in accordance with Section 2.7(e), the Stated Amount
shall be reduced by an amount equal to the amount of the PPA LOC Loan so
converted and the Maximum Stated Amount correspondingly reduced.

        (d) 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 PECO a notice in the form of Annex E to the PPA Letter of Credit (a
"TERMINATION NOTICE"), which notice shall be given at least sixty (60) days
prior to the date of termination referred to in such notice. After the delivery
by the Issuing Bank of a Termination Notice, the Stated Amount shall be neither
increased, nor reinstated upon payment of any PPA LOC Loans notwithstanding any
other provision of this Agreement to the contrary.

        (e) The Agent shall, solely for informational purposes, deliver to the
Partnership a copy of any Termination Notice given to the beneficiary under the
PPA Letter of Credit; PROVIDED, HOWEVER, that the Banks' ability to terminate
the PPA Letter of Credit shall not be contingent upon the Agent's delivery to
the Partnership 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 Partnership.

        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

                                       7
<PAGE>

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 reduction in the Maximum Stated Amount, change in the Stated Amount or
Expiration Date in respect of the PPA Letter of Credit or the 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. (a) The payment by the Issuing
Bank of a Drawing shall constitute the making by the Issuing Bank of a loan to
the Partnership in the amount of such payment. In the event that a Drawing is
not repaid by the Partnership 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 Partnership, 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 such
Drawing, for application to repay the Issuing Bank (each such loan by a Bank,
which shall be either a PPA LOC Loan or a PPA Term Loan, to be referred to as a
"PPA 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 PPA 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 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 Loan (either a PPA LOC Loan or a PPA Term Loan, as applicable) for all
purposes of this Agreement.

        (b) If a Non-Renewal Event shall have occurred, PECO shall be entitled
to make a Drawing on the PPA Letter of Credit in an amount equal to the Stated
Amount of the PPA Letter of Credit as in effect immediately prior to such
Drawing and the PPA Letter of Credit shall thereupon terminate.

        Section 2.5 FEES. The Partnership shall pay the following fees to the
Agent for the respective accounts of the persons specified below:

        (a) for the respective accounts of the Banks, a letter of credit fee
equal to the product of (i) the average daily Stated Amount and (ii) a per annum
rate equal to the average daily Applicable Margin for Eurodollar Rate Loans, as
in effect during the applicable period, payable quarterly in arrears on the
first Business Day of each February, May, August and November (each such
Business Day, a "QUARTERLY DATE") occurring after the Closing Date calculated on
the basis of a 360-day year for the actual number of days elapsed;

        (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) 0.125% per annum payable quarterly in arrears on each Quarterly Date
occurring after the Closing Date calculated on the basis of a 360-day year for
the actual number of days elapsed;

                                       8
<PAGE>

               (c) from and after the Closing Date to and including April 1,
2001, for the account of each Bank an annual commitment fee, payable quarterly
in arrears on each Quarterly Date occurring after the Closing Date and
calculated on the basis of a 360 day year for the number of days elapsed in an
amount equal to 0.375% of the Additional Commitment; and

               (d) such other fees specified in the fee letter among the
Partnership, the Agent.

        Section 2.6 INTEREST. (a) RATE. The Partnership shall pay interest on
the unpaid principal amount of each PPA Loan for each day from the date such PPA
Loan is made until such principal amount has been paid in full as follows:

        (i) BASE RATE LOANS. As to Base Rate Loans for each day until due at a
rate PER ANNUM equal to (x) the sum of the Adjusted Base Rate plus (y) the
Applicable Margin as in effect on such day payable monthly in arrears on the
first Business Day of each month; and

        (ii) EURODOLLAR RATE LOANS. As to Eurodollar Rate Loans, for each day
until due at a rate PER ANNUM equal to the sum of (x) the Eurodollar Rate plus
(y) as in effect on such day 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.

        (iii) DEFAULT INTEREST. Interest payments for each day on any principal
amounts that have not been paid when due shall be payable at the Adjusted Base
Rate plus the Applicable Margin as in effect on such day plus 2%

        (b) METHOD OF ELECTING INTEREST RATES. (i) Each PPA Loan shall
constitute a Base Rate Loan unless the Partnership elects otherwise pursuant to
the following provisions of this Section 2.6(b).

        (ii) Each PPA Loan shall constitute a Base Rate Loan or a Eurodollar
Rate Loan as the Partnership may elect in accordance with this Section 2.6(b).
If no such election is timely made with respect to a PPA Loan, such PPA Loan
shall constitute a Base Rate Loan in accordance with Section 2.6(b)(i), provided
that, in the case of PPA Term Loans that arise on the occasion of a conversion
from PPA LOC Loans in accordance with Section 2.7(d) or 2.7(e), such PPA Term
Loans shall be continued as the same type of PPA Loan (i.e., Base Rate Loan or
Eurodollar Loan), and if any such PPA LOC Loan was a Eurodollar Loan, the then
current Interest Period shall continue after such conversion, until the end of
such Interest Period, at which time the provisions for election of Interest
Periods contained in this Section 2.6(b) shall apply. The Partnership may from
time to time elect to change or continue the interest rate borne by each PPA
Loan, subject to the conditions set forth below, as follows:

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

                (B) with respect to PPA Loans that are Eurodollar Rate Loans,
        the Partnership may elect to convert all or any portion of such PPA
        Loans to Base Rate Loans or elect to continue all or any portion of such
        PPA Loans as

                                       9
<PAGE>

        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 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 Loan.

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

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

                (D) if such PPA 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 Loans 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.

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

        (c) FUNDING LOSSES. If the Partnership 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 Partnership 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 Partnership 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 Partnership shall indemnify

                                       10
<PAGE>

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 Partnership 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 Partnership 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 Partnership, whereupon until the Agent, or such Bank
through the Agent, notifies the Partnership 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
Loans into Eurodollar Rate Loans shall be suspended and (B) each outstanding
Eurodollar Rate Loan, or if a Bank only 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.

        (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. (a) The Partnership shall repay the principal
amount of each PPA LOC Loan in accordance to the provisions of Exhibit C
applicable to PPA LOC Loans. Each PPA LOC Loan shall mature and be paid in full
on the applicable PPA LOC Loan Required Payment Date.

                                       11
<PAGE>

        (b) The Issuing Bank shall reduce the Stated Amount by the principal
amount of each PPA LOC Loan.

        (c) Subject to Sections 2.2 and 6.2, the Issuing Bank shall, upon
receipt of written notice from the Partnership, reinstate the Stated Amount to
the extent of any repayment or prepayment of the principal amount of any PPA LOC
Loan; provided, that such reinstatement shall not cause the Stated Amount to
exceed the Maximum Stated Amount as then in effect. The Issuing Bank shall
provide notice to PECO in the form of Annex D if the Letter of Credit is
reinstated.

        (d) Each PPA Term Loan (including the PPA Term Loans made after a
Non-Renewal Event and any PPA Term Loan made upon a conversion of a PPA LOC Loan
after the occurrence of a Term Conversion Event) shall, in accordance with
Exhibit C, (i) amortize and be payable on successive Scheduled Payment Dates in
amounts of principal and interest computed on a Mortgage Basis, and (ii) finally
mature and be due and payable on the applicable PPA Term Loan Required Payment
Date in the amount of remaining principal thereof and accrued interest thereon.

        (e) If a Term Conversion Event shall have occurred as to any PPA LOC
Loan, then from and after the date such Term Conversion Event occurs, the Agent
may, subject to the approval of the Required Banks and upon 15 Business Days'
prior written notice to the Partnership and the other Senior Parties, convert
such PPA LOC Loan into a PPA Term Loan.

        Section 2.8 PREPAYMENTS. The Partnership 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 Partnership 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. PPA Term Loans shall be prepaid ratably with the Bonds
in the event the Bonds are prepaid, provided that in the event that an LOC Sweep
Notice shall have been given, the PPA Term Loans may be prepaid in accordance
with Section 3.3(c) of the Collateral Agency Agreement.

        All prepayments made hereunder shall be applied by the Agent and the
Banks against the installments of principal amount of outstanding PPA Loans of a
particular class (i.e., PPA LOC Loans or PPA Term Loans), in inverse order of
maturity; such prepayments shall first be applied to the prepayment of
outstanding Base Rate Loans of a particular class (i.e., PPA LOC Loans or PPA
Term Loans) to the extent thereof and then to the prepayment of outstanding
Eurodollar Rate Loans of such class.

        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 Partnership shall make each payment
hereunder not later than 10:00 a.m. (New York City time), on the day when due to
the Agent at its address set

                                       12
<PAGE>

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 Drawings), interest or fees ratably
(other than amounts payable for the account of the Issuing Bank pursuant to
Section 2.5(a) and (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 Partnership before the
date on which any payment is due to the Banks hereunder that the Partnership
will not make such payment in full, the Agent may assume that the Partnership
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 Partnership 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 Partnership to each of the Banks and the
Agent under this Agreement will be made without set-off, counterclaim or other
defense.

        Section 2.11 COMPUTATION OF INTEREST AND FEES. All computations of
interest hereunder for Eurodollar Rate Loans shall be made on the basis of a
year of 360 days and for Base Rate Loans shall be made on the basis of a year of
365/366 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 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 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 Partnership hereunder, such amount shall be due and
payable not later than 10 Business Days after receipt by the Partnership 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 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 participation (which it shall be deemed
to have purchased

                                       13
<PAGE>

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 Partnership 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 Partnership 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 Partnership 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 Partnership 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 Partnership
resulting from all PPA Loans shall be evidenced by this Agreement.

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

        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 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 PPA Loans or Eurodollar Rate Loans (except for changes in the
        rate of tax on the net income of the 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

                                       14
<PAGE>

                (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 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 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 Partnership 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 Partnership 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 Partnership 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
15 Business Days after demand by the Agent, the Partnership 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 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 Partnership of such determination,
and the Partnership 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 Loan during such Eurocurrency Reserve Period
at a rate PER ANNUM which shall, during each monthly period applicable to such
PPA 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 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 Partnership 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

                                       15
<PAGE>

before the date on which the Agent first notifies the Partnership 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 Partnership at the time that
it is otherwise required to pay interest in respect of such PPA 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 Partnership of the
existence of a Eurocurrency Reserve Period, the Agent, or the applicable Bank
through the Agent, shall promptly notify the Partnership of any termination
thereof, at which time the Partnership 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
Partnership 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 Partnership 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 15 Business Days after the delivery of such
certificates by the Agent, the Partnership 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 Partnership to the Agent and the
Banks under this Agreement 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 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 Loan or the branch of the Agent
through which it renders its services as the Agent ("EXCLUDED TAXES"). If the
Partnership 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.

                                       16
<PAGE>

        (b) To the extent permitted by law, without duplication of amounts paid
by the Partnership under Section 2.17(a), the Partnership 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
Partnership office (but in no event later than 60 days) 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 Partnership 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 Partnership will provide evidence that all Taxes imposed on
payments under this Agreement, any PPA Loan have been fully paid to the
appropriate authorities by delivering official receipts or notarized copies to
the Agent within 15 Business Days after payment. The Partnership will compensate
the Agent or any Bank that has to pay any Taxes because the Partnership 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 Partnership of
its intent to make such payment.

        (d) If the Partnership 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 Partnership's expense, keep the Partnership fully
informed about the progress of the contest, consult in good faith with the
Partnership's counsel regarding conduct of the contest, and not compromise or
otherwise settle the contest without the Partnership'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 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
Partnership has provided the Agent or such Bank an opinion of independent tax
counsel selected by the Partnership 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

                                       17
<PAGE>

requested by the Agent or such Bank, the Partnership 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 Partnership 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
Partnership 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
Partnership has paid the amount required.

        (e) If the Partnership so requests within 10 days of notice to the
Partnership 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 Partnership may reasonably request, each Bank agrees that it will deliver
to the Agent and the Partnership duly completed forms of any applicable
jurisdiction or other documentation reasonably satisfactory to the Agent and the
Partnership 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 Partnership
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.

        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 Partnership,
whereupon until the Agent, or such Bank through the Agent, notifies the
Partnership 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 or convert outstanding PPA Loans into Eurodollar Rate Loans, shall be
suspended. Before giving any notice to the Partnership pursuant to this Section,
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 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 make or continue such PPA 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 or continue such PPA Loan to
such day; PROVIDED, that the Partnership shall not be obligated to make any
payment pursuant to Section 2.6(c) as a result of such conversion. If the
Partnership 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.

                                       18

        Section 2.19 REDUCTION IN COMMITMENTS/REIMBURSEMENTS. The Partnership
shall have the right to refinance the Commitment and any outstanding PPA 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 2.20 RIGHT OF SET-OFF. Subject to the terms and conditions of
the Collateral Agency Agreement, the Partnership 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 Partnership or any Person other than the Collateral Agent (any
such notice being hereby expressly waived by the Partnership 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 Partnership against
any and all of the Obligations and liabilities of the Partnership 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.

                         REPRESENTATIONS AND WARRANTIES

        Section 5.1 COVENANTS. So long as any Commitment is in effect, the PPA

                                   ARTICLE VI

        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) any principal of any PPA Loans is not paid in full within 5 days

<PAGE>

        (c) an "Event of Default" under the Common 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) after giving any required notice to
the beneficiary of the PPA Letter of Credit and the lapse of the time period
required prior to termination of the PPA Letter of Credit, terminate the PPA
Letter of Credit in accordance with Section 2.2(d), (ii) declare the
Obligations, all interest thereon and all other amounts payable under this
Agreement to be forthwith due and payable, including but not limited to the
amount of any and all PPA 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 a termination
of the PPA Letter of Credit in accordance with Section 2.2(d), whereupon the
Obligations, all such interest and all such amounts shall become and be
immediately due and payable, without presentment, demand, protest or further
notice of any kind, all of which are hereby expressly waived by the Partnership,
(iii) terminate the ability of the Partnership to cause reinstatement of the
Stated Amount through the reimbursement of Drawings, as contemplated by the
terms hereof or (iv) terminate the ability of the Partnership to continue PPA

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 Common Agreement and the Trustee accelerates amounts due under the
Common Agreement, the Maximum Stated Amount shall be entitled to
collateralization pursuant to the terms of the Collateral Agency Agreement 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 Common Agreement, 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 Maximum Stated Amount
shall be transferred by the Collateral Agent to the Agent. 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.

                            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 Document or Financing Document;

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

        (c) the existence of any claim, set-off, defense or other right that the
Partnership 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 Document 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 Document, 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
Partnership, the Agent and the Banks (including the Issuing Bank), the
Partnership 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

                                       22
<PAGE>

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 Partnership shall have a claim against the Issuing Bank, and the Issuing
Bank shall be liable to the Partnership, to the extent of any direct, as opposed
to consequential, damages suffered by the Partnership that the Partnership
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
Document), 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;
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 Document 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, the
Issuing Bank shall act solely as issuer of the PPA 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 Partnership or any other party to any Project
Document.

        (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 to create, perfect or maintain the
existence or perfected status of any security interest created pursuant to any
such Credit Documents.

                                       23
<PAGE>

        Section 8.2 AGENT'S RELIANCE, ETC. Neither the Agent nor the Issuing
Bank nor any of its or 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 Document, 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 Partnership 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 Document or other Project Document; (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 Document on the
part of the Partnership or any Affiliate or to inspect the property (including
the books and records) of the Partnership 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 Document 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 Document 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 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 the 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 Partnership, any Affiliate thereof and any Person that may do business
with or own securities of the Partnership 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. The Banks agree to indemnify the Agent and
the Issuing Bank (to the extent not promptly reimbursed by the Partnership and
without limiting the obligation of the Partnership 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,

                                       24
<PAGE>

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 Document or any action taken or
omitted by the Agent under any Credit Document or other Project Document;
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 reimburse the Agent promptly upon demand for its ratable
share of any costs and expenses payable by the Partnership under Section 9.4, to
the extent that the Agent is not reimbursed for such costs and expenses by the
Partnership.

        Section 8.6 SUCCESSOR AGENT. The Agent may resign at any time by giving
30 days prior written notice thereof to the Banks and the Partnership 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 Partnership,
which shall not be unreasonably withheld. 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 Partnership (which
shall not be unreasonably withheld), 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 any appointment as Agent hereunder by a successor Agent, such
successor Agent shall thereupon succeed to and become vested with all of the
rights, powers, privileges and duties of the retiring Agent, and the retiring
Agent shall be discharged from its duties and obligations under the Credit

while it was agent under this Agreement.

Agent to execute and deliver such instruments and other documents as the Agent
may deem desirable to confirm such consent, to the release of the Liens on the
Collateral, including any release in connection with any sale, transfer or other
disposition of the Collateral or any part thereof, in accordance with the
Project Documents.

        Section 9.4 COSTS AND EXPENSES. The Partnership agrees to pay on demand
(i) all reasonable costs and expenses of the Agent and the Banks (including the
Issuing Bank) in connection with the preparation, execution, delivery,
syndication, administration, modification and amendment of this Agreement, the
other Credit Documents, and the other documents to be delivered hereunder,
including (a) the reasonable fees and out-of-pocket expenses of counsel for the
Agent and the Banks with respect thereto and with respect to advising the Agent
and the Banks as to their rights and responsibilities, or the perfection,
protection or reservation of rights or interests, under this Agreement, the
other Credit Documents, the other Project Documents and the other documents to
be delivered hereunder, (b) the reasonable fees and expenses of any consultants,
auditors or accountants engaged by the Agent with the written consent (which
shall not be unreasonably withheld) of the Partnership pursuant hereto, and (ii)
all reasonable costs and expenses of the Agent and the Banks (including the
Issuing Bank) (including reasonable counsel fees and expenses of the Agent and
the Banks) in connection with the enforcement (whether through negotiations,
legal proceedings or otherwise) of this Agreement, the other Credit Documents,
the other Project Documents and the other documents to be delivered hereunder,
whether in any action, suit or litigation, bankruptcy, insolvency or similar
proceeding. In addition, the Partnership shall pay any and all stamp and other
taxes and fees payable or determined to be payable in connection with the
execution, delivery, filing and recording of the aforementioned documents, and
the Partnership agrees to indemnify and hold the Agent and the Banks (including
the Issuing Bank) harmless from and against any and all liabilities with respect
to or resulting from any delay in paying or omission to pay any of the
foregoing.

        Section 9.5 APPLICATION OF MONEY. If any sum paid or recovered in
respect of the Obligations is less than the amount then due, the Agent may apply
that sum to principal, interest, fees or any other amount due under this
Agreement in such proportions and order and generally in such manner as the
Agent shall reasonably determine.

        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 invalidating the remaining
provisions of this Agreement or affecting the 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, partners, stockholders, officers, directors, representatives or
employees of the Partnership, other than the Partnership (each a "NON-RECOURSE
PARTY"), for any payment due hereunder or under any other Financing Document or
Security Document from the Partnership 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 Partnership, or breach of any
representation or warranty made hereunder or thereunder by the Partnership,
shall be against the Partnership and its assets, it being expressly understood
by the Senior Parties that such obligations of the Partnership are obligations
solely of the Partnership and that no such

                                       27
<PAGE>

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 Partnership the validity of any Credit Document, as applicable, prevent
the taking of any action permitted by law against the Partnership 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 Partnership 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 Partnership, the Agent and the Banks and their
respective successors and assigns, except that the Partnership 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 Partnership, 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 (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 33 1/3% of the Maximum 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
Partnership). Upon (i) such execution of such Assignment and Acceptance and (ii)
delivery of a copy thereof to the Partnership 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.

        (b) Any Bank may, from time to time, sell or offer to sell participating
interests in any PPA Loans owing to such Bank, such Bank's interest in 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 determined by the selling Bank, without the
consent of or notice to the Partnership, 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

                                       28
<PAGE>

Partnership, 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 Partnership, including the right, subject to Section 9.1, 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, subject to Section
9.1, 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. 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 Partnership 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 as set forth in Section 2.20 hereof to the
same extent as if the amount of its participating interest was owing directly to
it as a Bank under this Agreement. The Partnership 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 Partnership furnished to such Bank by or on
behalf of the Partnership; provided, however, that prior to any such disclosure,
the Person receiving such disclosure shall sign such confidentiality agreements
as the Partnership may reasonably request.

        Section 9.10 INDEMNIFICATION. The Partnership 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
Partnership or the Collateral, or the omission or alleged omission to state any
fact concerning the Partnership 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 and enforcing the rights
and remedies of the Agent and the Banks under the Project Documents; (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 Document; or (vii) any failure by the Partnership to comply
with any Environmental Laws; PROVIDED, HOWEVER, that the Partnership 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

                                       29
<PAGE>

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 Partnership, 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 Partnership in writing, enclosing a
copy of all papers served, but the omission so to notify the Partnership 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 Partnership shall not be liable for any settlement of any such action
effected without the Partnership's prior written consent. In case any such
action shall be brought against any Indemnified Party and it shall notify the
Partnership of the commencement thereof, the Partnership 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 Partnership to such Indemnified Party of the Partnership's
election so to assume the defense thereof, the Partnership 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
Partnership, (ii) the Indemnified Party shall have reasonably concluded that
there may be a conflict of interest between the Partnership and the Indemnified
Party in the conduct of the defense of such action (in which case the
Partnership shall not have the right to direct the defense of such action on
behalf of the Indemnified Party) or counsel for the Partnership shall have
declined to represent the Indemnified Party in light of a potential conflict of
interest or (iii) the Partnership shall not in fact have employed counsel
reasonably satisfactory to the Indemnified Party to assume the defense of such
action.

feasibility of its construction. To induce and facilitate the construction of
the plant, the Development Authority of Heard County ("Authority") has made
available to Tenaska taxable revenue bond financing ("Bond Financing") of up to
$400,000,000.00. Under that financing, the Authority will own the land,
building, equipment and other property purchased with the bond proceeds and will
lease the property to Tenaska under a lease with a term in excess of twenty-five
(25) years (the "Lease"). At the end of the lease period, Tenaska will have the
obligation to purchase the land, building and equipment from the Authority for a
nominal sum. The Authority will use Tenaska's lease payments to retire the bond
issue indebtedness, and the Authority will retain for its use and the use of
Heard County any lease payments in excess of those needed to retire the bond
issue indebtedness.

         This bond financing and the ad valorem tax consequences resulting
therefrom is a major consideration for Tenaska in its determination of the
feasibility of construction of the plant. The Commissioners, the Board and
Tenaska recognize and agree that the Authority's ownership interest in the real
and personal property leased to Tenaska is not subject to ad valorem taxation.
Likewise, Commissioners, the Board and Tenaska recognize and agree that
Tenaska's leasehold interest in the property it leases from the Authority
pursuant to the Lease will be subject to ad valorem taxation.

         In order to provide Tenaska with sufficient information and certainty
upon which it can base its construction decision, the Commissioners, the Board
and Tenaska agree that it is important to set forth at this time the methodology
by which it is agreed that Tenaska's leasehold interest under the Lease will be
valued.
That methodology is as follows:

         1. There will be no value to the Lease and therefore no real property
or personal property taxes on the property which is subject to the Lease until
January 1 of the year after the year in which the construction of the plant is
completed and revenue generation operations commence thereon.

<PAGE>

         2. Ad valorem taxes will commence in the year after the year in which
the plant is completed and revenue generation operations commence thereon.
Thereafter, for a period of twenty (20) years, the taxes will be derived by
reference to the hypothetical amount of the cumulative principal reduction of
the outstanding bond indebtedness ("Cumulative Principal Reduction") determined
as if the principal amount of the outstanding bond indebtedness were amortized
by equal quarterly payments of principal and interest at a rate equal to six
percent (6%) per annum over such period of twenty (20) years, as more
specifically set forth below:

         First, determine the dollar amount of the outstanding bond financing
proceeds that were invested in engineering, procurement and construction costs
("EPC") in (a) Leased Land and Buildings and (b) Leased Equipment, as each are
defined in the Lease.

         Second, for the Leased Land and Buildings (collectively) and for the
Leased Equipment, and as of the first day of each of the twenty years of the
hypothetical amortization, compute the Cumulative Principal Reduction which will
have been deemed to have been paid under such amortization through such date
[computed separately for the Leased Land and Buildings (collectively) and for
the Leased Equipment].

         Third, to take into account depreciation, the Cumulative Principal
Reduction in each year of the twenty year period shall be multiplied by a factor
set forth below:

         Fourth, to determine the property value for ad valorem tax purposes in
any year of such twenty (20) year period, compute the product of (a) the
Cumulative Principal Reduction of the Leased Land and Buildings (collectively)
and the Leased Equipment through such year and (b) the factor in Third above.
Such product shall be deemed to be the fair market value of the Leased Land and
Buildings and of the Leased Equipment in such year. Such product shall
thereafter be multiplied by forty percent (40%) to determine the assessed value
of each such category for such year and thereafter multiplied by the millage
rate, established by Heard County with respect to such year, to determine the
tax in each such year of such twenty (20) year period.

         An example of the application of this methodology, assuming a millage
rate of 25.00 and assuming EPC of Leased Land and Buildings of $1,757,000.00 and
Leased Equipment of $228,243,000.00 is attached hereto as Exhibit "A" and
Exhibit "B".

         After the expiration of the twenty (20) year period described in this
paragraph 2, the valuation of the Leased Land, Buildings and Leased Equipment,
to the extent not governed by paragraph 4, will be determined under the
methodology then employed by the Board.

         3. Repairs or Replacement. Repairs or replacement of items of Leased
Equipment whenever occurring shall be treated as part of the Leased Equipment
and shall have the same value as the items of Leased Equipment so repaired or
replaced and shall not affect the value of the Leased Equipment for tax purposes
or the ultimate tax liability of Tenaska.

         4. Plant Expansion. The Bond Financing has been sized to accommodate a
plant expansion within ten (10) years from the sale of the first bonds. If,
after the construction of the initial plant is completed and revenue generation
operations begin, any Buildings or Leased Equipment are thereafter purchased
through the Bond Financing as part of a plant expansion, such Buildings and
Leased Equipment shall be entitled to a twenty year tax abatement (with the
Lease accordingly extended as necessary) on the same methodology described in
paragraphs 1, 2 and 3 above. The plant expansion will not be taxed during its
construction, as set forth in paragraph 1, and a separate twenty (20) year
hypothetical amortization of the bonds issued in connection with such plant
expansion will be established based upon the EPC for such plant

                                      -3-

expansion effective the year after the plant expansion is completed and revenue
generation operations commence thereon, using the methodology in paragraph 2
above, adjusted as needed so as to afford the plant expansion a full 20-year tax
abatement under the formula described herein.

         By their signatures appearing at the bottom of this agreement, the
Commissioners, the Board and Tenaska concur and agree to be bound by the above
valuation of Tenaska's leasehold interest for Heard County ad valorem tax
purposes under such Authority Bond financing and Lease. This Agreement shall
inure to the benefit of Tenaska, its successors and assignees, including without
limitation, its lenders.
