               (b) LIBOR Loan Interest Periods.

                  (i) In connection with each LIBOR Loan, Borrower may, pursuant
         to the applicable Notice of Borrowing or Notice of Conversion of Loan

         or, if available to all Banks and made available by Administrative
         Agent, nine or 12 months. Notwithstanding anything to the contrary
         herein, (A) any Interest Period which would otherwise end on a day
         which is not a Banking Day shall be extended to the next succeeding

         Banking Day of a calendar month (or on a day for which there is no

         Interest Period) shall end on the last Banking Day of a calendar month;
         (C) Borrower may not select Interest Periods which would leave a
         greater principal amount of Loans subject to Interest Periods ending

         principal amount of Loans scheduled to be outstanding after such date;

         extend beyond the Loan Maturity Date; (E) LIBOR Loans for each Interest
         Period shall be in the amount of at least $1,000,000; (F) Borrower may
         not at any time have outstanding more than ten different Interest
         Periods relating to LIBOR Loans; (G) if Borrower fails to specify an
         Interest Period for any LIBOR Loan in accordance with the terms of this
         Agreement, (1) in the case of a requested Loan, Borrower shall be
         deemed to have specified such Loans as Base Rate Loans in the
         applicable Notice of Borrowing, and (2) in the case of outstanding
         Loans, such Loans shall automatically convert to Base Rate Loans on the
         last day of the current Interest Period therefor; and (H) for the
         period from and after the Closing Date to and including the date which
         is six months after the Closing Date, Borrower may only select a one
         month Interest Period.

                  (ii) Borrower may contact Administrative Agent at any time
         prior to the end of an Interest Period for a quotation of Interest
         Rates in effect at such time for given Interest Periods and
         Administrative Agent shall promptly provide such quotation. Borrower
         may select an Interest Period telephonically within the time periods
         specified in Section 2.1.7, which selection shall be irrevocable on and
         after the applicable Minimum Notice Period. Borrower shall confirm such
         telephonic notice to Administrative Agent by delivering to
         Administrative Agent by telecopy on the day such notice is given a
         written notice in substantially the form of Exhibit C-3 hereto (a
         "Confirmation of Interest Period Selection"). Borrower shall promptly
         deliver to Administrative Agent the original of the Confirmation of
         Interest Period Selection initially delivered by telecopy.
         Administrative Agent shall as soon as practicable (and, in any case,
         within two Banking Days after delivery of the Confirmation of Interest
         Period

                                       6
<PAGE>   19

         Selection) notify Borrower of each determination of the Interest
         Rate applicable to each Loan.

               (c) Interest Computations. All computations of interest on Base
Rate Loans shall be based upon a year of 365 days (or 366 days in a leap year),
and shall be payable for the actual days elapsed (including the first day but
excluding the last day). All computations of interest on LIBOR Loans shall be
based upon a year of 360 days, and shall be payable for the actual days elapsed
(including the first day but excluding the last day). Borrower agrees that all
computations by Administrative Agent of interest shall be conclusive and binding
in the absence of manifest error.

         2.1.4 Register.

               (a) Administrative Agent shall maintain, at its address referred
to in Section 11.1, a register for the recordation of the names and addresses of
Banks and the Loan Commitments and Loans of each Bank from time to time (the
"Register"). The Register shall be available for inspection by Borrower at any
reasonable time and from time to time upon reasonable prior notice.

               (b) Administrative Agent shall record in the Register (i) the
Loan Commitment and the Loans from time to time of each Bank, (ii) the interest
rates applicable to all Loans and the effective dates of all changes thereto,
(iii) the Interest Period for each LIBOR Loan, (iv) the date and amount of any
principal or interest due and payable or to become due and payable from Borrower
to each Bank hereunder, (v) each repayment or prepayment in respect of the
principal amount of the Loans of each Bank, (vi) the amount of any sum received
by Administrative Agent hereunder for the account of Banks and each Bank's share
thereof and (vii) such other information as Administrative Agent may determine
is necessary for administering the Loans and this Agreement. Any such
recordation shall be conclusive and binding on Borrower and each Bank, absent
manifest error; provided that neither failure to make any such recordation, nor
any error in such recordation, shall affect any Bank's Loan Commitment or
Borrower's Obligations in respect of any applicable Loans or otherwise; and
provided, further that in the event of any inconsistency between the Register
and any Bank's records, the recordations in the Register shall govern.

         2.1.5 Promissory Notes. If requested by any Bank, the obligation of
Borrower to repay the Loans made by such requesting Bank and to pay interest
thereon at the rates provided herein shall be evidenced by a promissory note in
the form of Exhibit B hereto (a "Note"), each payable to the order of such
requesting Bank and in the principal amount of such Bank's Loan Commitment.
Borrower authorizes each such requesting Bank to record on the schedule annexed
to such Bank's Note, the date and amount of each Loan made by such Bank, and
each repayment or prepayment of principal thereunder and agrees that all such
notations shall constitute prima facie evidence of the matters noted; provided
that in the event of any inconsistency between the Register and any Bank's
records, the recordations in the Register shall govern; and provided, further
that neither the failure to issue any Note or to make any such notation, nor any
error in such notation, shall affect the validity of Borrower's obligations to
repay the full unpaid principal amount of the Loans or the duties of Borrower
hereunder or

                                       7
<PAGE>   20

thereunder. Borrower further authorizes each Bank which receives a Note to
attach to and make a part of such Bank's Note continuations of the schedule
attached thereto as necessary.

         2.1.6 Loan Funding.

               (a) Notice. Each Notice of Borrowing shall be delivered by
Borrower to Administrative Agent in accordance with Section 11.1. Administrative
Agent shall promptly notify each Bank of the contents of each Notice of
Borrowing.

               (b) Pro Rata Loans. All Loans shall be made on a pro rata basis
by Banks in accordance with their respective Proportionate Shares of such Loans,
with each Loan to consist of a Loan by each Bank equal to such Bank's
Proportionate Share of such Loan.

               (c) Bank Funding. Each Bank shall, before 11:00 a.m. on the
applicable Funding Date, make available to Administrative Agent by wire transfer
of immediately available funds in Dollars to the account of Administrative Agent
most recently designated by it for such purpose, such Bank's Proportionate Share
of such Loan. The failure of any Bank to make the Loan to be made by it as part
of any Loan shall not relieve any other Bank of its obligation hereunder to make
its Loan on the applicable Funding Date. No Bank shall be responsible for the
failure of any other Bank to make the Loan to be made by such other Bank on the
applicable Funding Date.

     Unless Administrative Agent shall have been notified by any Bank prior to
the applicable Funding Date that such Bank does not intend to make available to
Administrative Agent the amount of such Bank's Proportionate Share of such Loan
requested on such date, Administrative Agent may assume that such Bank has made
such amount available to Administrative Agent on such date in accordance with
the prior paragraph and Administrative Agent may, in its sole discretion and in
reliance upon such assumption, make available to Borrower a corresponding amount
on such date. If such corresponding amount is not in fact made available to
Administrative Agent by such Bank, Administrative Agent shall be entitled to
recover such corresponding amount on demand (and, in any event, within two
Banking Days from the applicable Funding Date) from such Bank together with
interest thereon, for each day from the applicable Funding Date until the date
such amount is paid to Administrative Agent, at the Federal Funds Rate for the
first two Banking Days after such date. If such Bank pays such amount to
Administrative Agent, then such amount shall constitute such Bank's
Proportionate Share of such Loan included in such Loan. If such Bank does not
pay such corresponding amount forthwith upon Administrative Agent's demand
therefor or within two Banking Days from the applicable Funding Date,
Administrative Agent shall promptly notify Borrower and Borrower shall
immediately pay such corresponding amount to Administrative Agent together with
interest thereon, for each day from the applicable Funding Date until the date
such amount is paid to Administrative Agent, at the rate then payable under this
Agreement for Base Rate Loans. Nothing in this Section 2.1.6(c) shall be deemed
to relieve any Bank from its obligation to fulfill its Obligations hereunder or
to prejudice any rights that Borrower may have against any Bank as a result of
any default by such Bank hereunder.

               (d) Development Account. No later than 1:00 p.m. on the date
specified in each Notice of Borrowing, if the applicable conditions precedent
listed in Article 3

                                       8
<PAGE>   21

have been satisfied or waived in accordance with the terms thereof and, subject
to Section 2.1.6(c) above, to the extent Administrative Agent shall have
received the appropriate funds from Banks, Administrative Agent will make
available the Loans requested in such Notice of Borrowing (or so much thereof as
Banks shall have approved pursuant to this Agreement) in Dollars and in
immediately available funds, at Administrative Agent's New York Branch, and
shall deposit such Loans into the Development Account.

         2.1.7 Conversion of Loans. Borrower may convert Loans from one Type of
Loans to another Type; provided, however, that (a) any conversion of LIBOR Loans
into Base Rate Loans shall be made on, and only on, the first day after the last
day of an Interest Period for such LIBOR Loans and (b) Loans shall be converted
only in amounts of $2,000,000 or more. Borrower shall request each such
conversion by delivering to Administrative Agent a written notice in the form of
Exhibit C-4 hereto, appropriately completed (a "Notice of Conversion of Loan
Type"), which specifies:

               (a) The Loans, or portion thereof, which are to be converted;

               (b) The Type into which such Loans, or portion thereof, are to be
converted;

               (c) If such Loans are to be converted into LIBOR Loans, the
initial Interest Period selected by Borrower for such Loans (which Interest
Period shall be selected in accordance with Section 2.1.3(b));

               (d) The Applicable Margin which will be in effect as of the day
of the requested conversion; and

               (e) The proposed date of the requested conversion (which shall be
a Banking Day and otherwise in accordance with this Section 2.1.7).

     Borrower shall so deliver each Notice of Conversion of Loan Type to
Administrative Agent so as to provide at least the applicable Minimum Notice
Period. Any Notice of Conversion of Loan Type shall be irrevocable and Borrower
shall be bound to make a conversion in accordance therewith. Each Notice of
Conversion of Loan Type shall be delivered by first-class mail or telecopy to
Administrative Agent at the office or to the telecopy number and during the
hours specified in Section 11.1; provided, however, that Borrower shall promptly
deliver to Administrative Agent the original of any Notice of Conversion of Loan
Type initially delivered by telecopy. Administrative Agent shall promptly notify
each Bank of the contents of each Notice of Conversion of Loan Type.

         2.1.8 Prepayments.

               (a) Terms of All Prepayments. Upon the prepayment of any Loan
(whether such prepayment is an optional prepayment under Section 2.1.8(b) or a
Mandatory Prepayment), Borrower shall pay to Administrative Agent for the
account of Bank which made such Loan, as applicable, (i) all accrued interest to
the date of such prepayment on the amount prepaid, (ii) all accrued fees to the
date of such prepayment of the amount being prepaid, and (iii) if such
prepayment is the prepayment of a LIBOR Loan on a day other than the last day of

                                       9
<PAGE>   22

an Interest Period for such LIBOR Loan, all Liquidation Costs incurred by such
Bank as a result of such prepayment. Notwithstanding the foregoing, but only in
respect of any Mandatory Prepayment, Borrower shall have the right, by giving
five Banking Days' notice to Administrative Agent, in lieu of prepaying a LIBOR
Loan on a day other than the last day of an Interest Period for such LIBOR Loan,
to deposit or cause Administrative Agent to deposit, into an account to be held
by Depositary Agent (which account shall be subjected to the Lien of the
Collateral Documents in a manner satisfactory to Administrative Agent) an amount
equal to the LIBOR Loans to be prepaid. Such funds shall be held in such account
until the expiration of the Interest Period applicable to the LIBOR Loan to be
prepaid at which time the amount deposited in such account shall be used to
prepay such LIBOR Loan and any interest accrued on such amount shall be
deposited in the Revenue Account. The deposit of amounts into such account shall
not constitute a prepayment of Loans and all Loans to be prepaid using the
proceeds from such account shall continue to accrue interest at the then
applicable interest rate for such Loans until actually prepaid. All amounts in
such account shall only be invested in Permitted Investments as directed by and
at the expense and risk of Borrower. Borrower may reborrow the principal amount
of any Loan which is prepaid.

               (b) Optional Prepayments. Subject to Section 2.1.8(a), Borrower
may, at its option and without penalty, upon five Banking Days' notice to
Administrative Agent, prepay any Loans in whole or in part in minimum amounts of
$5,000,000 or an incremental multiple of $1,000,000 in excess thereof.

               (c) Mandatory Prepayments.

                  (i) Borrower shall prepay (or cause to be prepaid) Loans to
         the extent required by Section 2.1.8(c)(ii), 2.1.8(c)(iii), 2.6.2, or
         7.2.2 of this Agreement, or any other provision of this Agreement or
         any other Credit Document which requires prepayment of Loans (such
         prepayment, "Mandatory Prepayment").

                  (ii) On the Banking Day on which Borrower receives the
         proceeds of any Final Equity Funding Payment or any Final Plant Funding
         Payment made by NRG Energy pursuant to and in accordance with Section
         2.1.1 or 2.1.2 of the NRG Energy Equity Undertaking, as the case may
         be, Borrower shall prepay the Loans in an aggregate amount equal to the
         amount of such proceeds.

                  (iii) In the event any Funded Working Capital Asset does not
         become a Converted Asset within eighteen months of the date of the
         initial funding of any such Funding Working Capital Asset hereunder,
         then Borrower shall prepay the Working Capital Loans in an aggregate
         principal amount equal to the amount of all Working Capital Loans made
         hereunder to fund any payments made in respect of such Funded Working
         Capital Asset.

     2.2 Total Commitments.

         2.2.1 Loan Commitment. The aggregate principal amount of all Loans
outstanding at any time or times shall not exceed $2,000,000,000 or, if such
amount is reduced by Borrower pursuant to Section 2.2.3, such lower amount (such
amount, as so reduced from

                                       10
<PAGE>   23

time to time, the "Total Loan Commitment"). The amount of each Bank's Loan
Commitment is set forth on Exhibit H hereto (which Exhibit shall be
automatically amended without further action upon the assignment of any such
Bank's Loan Commitment in accordance with the terms hereof to give effect to any
such assignment).

         2.2.2 Available Loan Commitments. Without limiting anything set forth
in Section 2.2.1, (a) the aggregate principal amount of all (i) Development
Loans outstanding at any time or times shall not exceed the then current
Available Development Loan Commitment and (ii) Working Capital Loans outstanding
at any time or times shall not exceed the then current Available Working Capital
Commitment, and (b) the sum of Development Loans outstanding plus Working
Capital Loans outstanding shall not exceed the then current Total Loan
Commitment.

         2.2.3 Reductions and Cancellations. Borrower may, from time to time
upon five Banking Days written notice to Administrative Agent, permanently
reduce, by an amount of $10,000,000 or an integral multiple of $1,000,000 in
excess thereof or cancel in its entirety the Total Loan Commitment and/or the
Total Working Capital Loan Commitment. Notwithstanding the foregoing, Borrower
may not reduce or cancel the Total Loan Commitment and/or the Total Working
Capital Loan Commitment if, after giving effect to such reduction or
cancellation, (a) the sum of the aggregate principal amount of all Loans then
outstanding would exceed the Total Loan Commitment, (b) the Available
Development Funds would not, in the reasonable judgment of the Technical
Committee and the Independent Engineer, be equal to or exceed remaining Project
Costs for all Approved Projects and Approved Turbines, or (c) such reduction or
cancellation would cause an Inchoate Default or an Event of Default, or have a
Borrower Material Adverse Effect or a Project Material Adverse Effect. Borrower
shall pay to Administrative Agent any Commitment Fees then due upon any
cancellation and, from the effective date of any reduction, the Commitment Fees
shall be computed on the basis of the Available Loan Commitment, as so reduced.
Once reduced or canceled, none of the Total Loan Commitment or the Working
Capital Loan Commitment may be increased or reinstated. Any reductions in the
Total Loan Commitment or the Total Working Capital Loan Commitment pursuant to
this Section 2.2.3 shall be applied ratably to each Bank's respective
Commitments in accordance with Section 2.5.1.

         2.2.4 Working Capital Loan Conversion to Development Loans. In the
event an Identified Project or Non-Identified Project satisfies the conditions
precedent to initial funding pursuant to Section 3.2, and prior to such initial
funding the assets assigned to such Project (as set forth in the applicable
Notice of Working Capital Loan Borrowing), if any, were Funded Working Capital
Assets, the Working Capital Loans associated with such Funded Working Capital
Assets shall be automatically converted for all purposes hereof into Development
Loans and shall cease to be considered outstanding Working Capital Loans,
including for purposes of Section 2.2.2, in each case such conversion being
effective as of the initial Funding Date with respect to such Project (the
Funded Working Capital Assets related to any such converted Working Capital
Loans shall be referred to herein as the "Converted Assets").

     2.3 Fees.

                                       11
<PAGE>   24

         2.3.1 Lead Arranger Fee Letter. Borrower shall pay to Lead Arranger and
Administrative Agent, for their respective accounts, the fees described in that
certain letter from NRG Energy to Lead Arranger dated April 4, 2001.

         2.3.2 Loan Commitment Fees. On the last Banking Day in each calendar
quarter (commencing on June 30, 2001) and on the earlier of (a) the Loan
Maturity Date and (b) the last Banking Day of the Loan Availability Period (or,
if the Total Loan Commitment is canceled prior to such date, on the date of such
cancellation), Borrower shall pay to Administrative Agent, for benefit of Banks,
accruing from the Closing Date or the first day of such quarter, as the case may
be, a commitment fee (the "Commitment Fee") for such quarter (or portion
thereof) then ending equal to the product of (i) 0.375% multiplied by (ii) the
daily average Available Loan Commitment for such quarter (or portion thereof)
multiplied by (iii) a fraction, the numerator of which is the number of days in
such quarter (or portion thereof) and the denominator of which is the number of
days in that year (365 or 366, as the case may be).

         2.3.3 Activation Fees. Concurrently with the making of the first Loan
in respect of each Non-Identified Project that becomes an Approved Project after
the date which is the six month anniversary of the Closing Date, Borrower shall
pay to Administrative Agent, for the benefit of the Banks, an activation fee
(the "Activation Fee") equal to the product of (a) 0.125% multiplied by (b) the
total amount of Project Costs in respect of such Non-Identified Project (as set
forth in such Non-Identified Project's Project Budget or Annual Operating
Budget, as the case may be, delivered in accordance with Section 3.2.22 or
Section 3.5.23).

     2.4 Other Payment Terms.

         2.4.1 Place and Manner. Borrower shall make all payments due to any
Bank or Administrative Agent hereunder to Administrative Agent, for the account
of such Bank or Administrative Agent (as the case may be), to The Bank of New
York, Federal Reserve Bank of New York ABA# 021000018, for further credit to
account #8900387734; Reference: NRG Finance Company I LLC, in Dollars and in
immediately available funds.

         2.4.2 Date. Borrower shall make all payments due to any Bank or
Administrative Agent hereunder not later than 12:00 noon on the date on which
such payment is due. Any payment made after such time on any day shall be deemed
received on Banking Day after such payment is received. Administrative Agent
shall disburse to each Bank each such payment received by Administrative Agent
for such Bank, such disbursement to occur on the day such payment is received if
received by 12:00 noon or if such payment is not received by 12:00 noon, on the
next Banking Day. Whenever any payment due hereunder shall fall due on a day
other than a Banking Day, such payment shall be made on the next succeeding
Banking Day (except in the case of any payment relating to a LIBOR Loan where
such next succeeding Banking Day is in the next calendar month, in which case
such payment shall be made on the next preceding Banking Day), and such
extension of time shall be included in the computation of interest or fees, as
the case may be.

         2.4.3 Late Payments. If any amounts required to be paid by Borrower
under this Agreement or the other Credit Documents (including principal or
interest payable on any Loan, and any fees or other amounts otherwise payable to
Administrative Agent or any Bank) remain

                                       12
<PAGE>   25

unpaid after such amounts are due, Borrower shall pay interest on the aggregate,
unpaid balance of such amounts from the date due until those amounts are paid in
full at a per annum rate equal to the Default Rate.

         2.4.4 Net of Taxes, Etc.

               (a) Taxes. Subject to each Bank's compliance with Section 2.4.6,
any and all payments to or for the benefit of Administrative Agent or any Bank
by Borrower hereunder or under any other Credit Document shall be made free and
clear of and without deduction, setoff or counterclaim of any kind whatsoever
and in such amounts as may be necessary in order that all such payments, after
deduction for or on account of any present or future taxes, levies, imposts,
deductions, charges or withholdings, and all liabilities with respect thereto
(excluding income and franchise taxes, which include taxes imposed on or
measured by the net income or capital of Administrative Agent or such Bank by
any jurisdiction or any political subdivision or taxing authority thereof or
therein solely as a result of a connection between such Bank and such
jurisdiction or political subdivision, other than a connection resulting solely
from executing, delivering or performing its obligations or receiving a payment
under, or enforcing, this Agreement or any Note) (all such non-excluded taxes,
levies, imposts, deductions, charges, withholdings and liabilities being
hereinafter referred to as "Taxes"), shall be equal to the amounts otherwise
specified to be paid under this Agreement and the other Credit Documents. If
Borrower shall be required by law to withhold or deduct any Taxes from or in
respect of any sum payable hereunder or under any other Credit Document to
Administrative Agent or any Bank, (i) the sum payable shall be increased as may
be necessary so that after making all required deductions (including deductions
applicable to additional sums payable under this Section 2.4.4), Administrative
Agent or such Bank receives an amount equal to the sum it would have received
had no such deductions been made, (ii) Borrower shall make such deductions and
(iii) Borrower shall pay the full amount deducted to the relevant taxation
authority or other authority in accordance with applicable Legal Requirements.
If Borrower shall make any payment under this Section 2.4.4 to or for the
benefit of Administrative Agent or any Bank with respect to Taxes and if
Administrative Agent or such Bank shall claim any credit or deduction for such
Taxes against any other taxes payable by Administrative Agent or such Bank to
any taxing jurisdiction then Administrative Agent or such Bank shall pay to
Borrower an amount equal to the amount by which such other taxes are actually
reduced; provided that the aggregate amount payable by Administrative Agent or
such Bank pursuant to this sentence shall not exceed the aggregate amount
previously paid by Borrower with respect to such Taxes. In addition, Borrower
agrees to pay any present or future stamp, recording or documentary taxes and
any other excise or property taxes, charges or similar levies (not including
income or franchise taxes) that arise under the laws of the United States of
America, the State of New York or any other state or jurisdiction where an
Approved Project, Approved Turbine or Funded Working Capital Asset is located
from any payment made hereunder or under any other Credit Document or from the
execution or delivery or otherwise with respect to this Agreement or any other
Credit Document (hereinafter referred to as "Other Taxes").

               (b) Indemnity. Borrower shall indemnify each Bank for the full
amount of Taxes and Other Taxes (including any Taxes or Other Taxes imposed by
any jurisdiction on amounts payable under this Section 2.4.4 paid by any Bank,
or any liability (including penalties, interest and expenses) arising therefrom
or with respect thereto), whether or

                                       13
<PAGE>   26

not such Taxes or Other Taxes were correctly or legally asserted; provided that
Borrower shall not be obligated to indemnify any Bank for any penalties,
interest or expenses relating to Taxes or Other Taxes arising from the
indemnitee's gross negligence or willful misconduct. Each Bank agrees to give
written notice to Borrower of the assertion of any claim against such Bank
relating to such Taxes or Other Taxes as promptly as is practicable after being
notified of such assertion, and in no event later than 180 days after the
principal officer of such Bank responsible for administering this Agreement
obtains knowledge thereof; provided that any Bank's failure to notify Borrower
of such assertion within such 180 days period shall not relieve Borrower of its
obligation under this Section 2.4.4 with respect to Taxes or Other Taxes arising
prior to the end of such period, but shall relieve Borrower of its obligations
under this Section 2.4.4 with respect to penalties and interest between the end
of such period and such time as Borrower receives notice from such Bank as
provided herein. Payments by Borrower pursuant to this indemnification shall be
made within 30 days from the date such Bank makes written demand therefor
(submitted through Administrative Agent), which demand shall be accompanied by a
certificate describing in reasonable detail the basis thereof. Each Bank agrees
to repay to Borrower any refund (including that portion of any interest that was
included as part of such refund with respect to Taxes or Other Taxes paid by
Borrower pursuant to this Section 2.4.4) received by such Bank for Taxes or
Other Taxes that were paid by Borrower pursuant to this Section 2.4.4 and to
contest, with the approval and participation of and at the expense of Borrower,
any such Taxes or Other Taxes which such Bank or Borrower reasonably believes
not to have been properly assessed.

               (c) Notice. Within 30 days after the date of any payment of Taxes
by Borrower, Borrower shall furnish to Administrative Agent, at its address
referred to in Section 11.1, the original or a certified copy of a receipt
evidencing payment thereof. Borrower shall compensate each Bank for all
reasonable losses and expenses sustained by such Bank as a result of any failure
by Borrower to so furnish such copy of such receipt.

               (d) Survival of Obligations. The obligations of Borrower under
this Section 2.4.4 shall survive the termination of this Agreement and the
repayment of the Obligations.

         2.4.5 Application of Payments. Payments made under Section 6.4.2(a)(vi)
of this Agreement or Section 5.4.2(a)(vi) of any Project Owner Guaranty shall be
applied to the Obligations associated with or attributable to the Approved
Project to which such payments relate. All other payments made under this
Agreement or the other Credit Documents and other amounts received by
Administrative Agent and Banks under this Agreement or the other Credit
Documents shall be applied as follows:

               (a) first, to any fees, costs, charges or expenses payable to
Administrative Agent, Documentation Agent, Lead Arranger, the members of the
Technical Committee and Banks hereunder or under the other Credit Documents
(such application to be made on a pro rata basis among such Persons),

               (b) second, to any fees, costs, charges or expenses payable to
Banks hereunder or under the other Credit Documents (such application to be made
on a pro rata basis among such Banks),

                                       14
<PAGE>   27

               (c) third, to any accrued but unpaid interest then due and owing
in respect of the Obligations, and

               (d) fourth, to outstanding principal then due and owing or
otherwise to be prepaid in respect of the Obligations; provided, with respect to
payments applied to outstanding principal then due and owing or otherwise to be
prepaid, such payments shall be applied as follows:

                  (i) first, to such debt associated with or attributable to
         Approved Projects which have achieved Provisional Acceptance (such
         application to be made on a pro rata basis among such Projects),

                  (ii) second, if all Loans associated with or attributable to
         Approved Projects which have achieved Provisional Acceptance have been
         paid, then to such debt associated with or attributable to Approved
         Projects which have not achieved Provisional Acceptance (such
         application to be made on a pro rata basis among such Projects), and

                  (iii) third, if all Loans associated with or attributable to
         Approved Projects which have or have not achieved Provisional
         Acceptance have been paid, then, to such debt associated with or
         attributable to Funded Working Capital Assets (such application to be
         made on a pro rata basis among such Funded Working Capital Assets).

               2.4.6 Withholding Exemption Certificates. Each Bank upon becoming
a Bank hereunder and each Person to which any Bank grants a participation (or
otherwise transfers its interest in this Agreement) agree that they will deliver
to Borrower and Administrative Agent either (a) if such Bank or Person is a
corporation established under the laws of the United States or any political
subdivision thereof, a copy of a United States Internal Revenue Service Form W-9
or (b) if such Bank or Person is not a corporation established under the laws of
the United States or any political subdivision thereof, a duly completed and
executed non-bank certificate in the form of Exhibit J hereto and two duly
completed copies of United States Internal Revenue Service Form W-8ECI or W-8BEN
or successor applicable form, as the case may be (claiming therein a reduction
in, or an exemption from, United States withholding taxes under an applicable
treaty). Each Bank which delivers to Borrower and Administrative Agent a Form
W-8ECI or W-8BEN pursuant to the preceding sentence further undertakes to
deliver to Borrower and Administrative Agent further copies of the Form W-8ECI
or W-8BEN, or successor applicable form, or other manner of certification or
procedure, as the case may be, on or before the date that any such form expires
or becomes obsolete or within a reasonable time after gaining knowledge of the
occurrence of any event requiring a change in the most recent forms previously
delivered by it to Borrower, and such extensions or renewals thereof as may
reasonably be requested by Borrower, certifying in the case of a Form W-8ECI or
W-8BEN that such Bank is entitled to receive payments under this Agreement
without (or with a reduced amount of) deduction or withholding of any United
States federal income taxes, unless in any such cases an event (including any
change in treaty, law or regulation) has occurred prior to the date on which any
such delivery would otherwise be required which renders all such forms
inapplicable or which would prevent a Bank from duly completing and delivering
any such form with respect to

                                       15
<PAGE>   28

it. Borrower shall not be obligated to pay any additional amounts in respect of
United States Federal income tax pursuant to Section 2.4.4 (or make an
indemnification payment pursuant to Section 2.4.4) to any Bank (including any
Person to which any Bank sells, assigns, grants a participation in, or otherwise
transfers its rights under this Agreement) if the obligation to pay such
additional amounts (or such indemnification) would not have arisen but for a
failure of such Bank to comply with its obligations under this Section 2.4.6.
Notwithstanding the foregoing or anything else to the contrary in this
Agreement, (i) no Bank or other Person shall be obligated to deliver any form,
certificate or document which it cannot deliver as a matter of law and (ii) if a
Bank or other Person is not entitled to a full exemption from the United States
withholding taxes in respect of interest payments as of the date such Bank or
Person becomes a Bank or participant hereunder, then Borrower shall not be
obligated to pay any additional amounts or make any indemnification payments
pursuant to Section 2.4.4 in respect of such taxes applicable as of such date.

     2.5 Pro Rata Treatment.

         2.5.1 Loans, Commitment Reductions, Etc. Except as otherwise provided
herein, (a) each Loan and each reduction of the Total Loan Commitment or the
Total Working Capital Loan Commitment shall be made or allocated among Banks pro
rata according to their respective Proportionate Shares of such Loans or
Commitments, as the case may be, (b) each payment of principal of and interest
on Loans shall be made or shared among Banks holding such Loans pro rata
according to the respective unpaid principal amounts of such Loans held by such
Banks and (c) each payment of Commitment Fees or Activation Fees shall be shared
among Banks pro rata according to (i) their respective Proportionate Shares of
the Commitments to which such fees apply and (ii) in the case of each Bank which
becomes a Bank hereunder after the date hereof, the date upon which such Bank so
became a Bank.

         2.5.2 Sharing of Payments, Etc. If any Bank shall obtain any payment
(whether voluntary, involuntary, through the exercise of any right of setoff, or
otherwise) on account of Loans owed to it in excess of its ratable share of
payments on account of such Loans obtained by all Banks entitled to such
payments, such Bank shall forthwith purchase from the other Banks such
participation in the Loans, as the case may be, as shall be necessary to cause
such purchasing Bank to share the excess payment ratably with each of them;
provided, however, that if all or any portion of such excess payment is
thereafter recovered from such purchasing Bank, such purchase from such Bank
shall be rescinded and each other Bank shall repay to the purchasing Bank the
purchase price to the extent of such recovery together with an amount equal to
such other Bank's ratable share (according to the proportion of (a) the amount
of such other Bank's required repayment to (b) the total amount so recovered
from the purchasing Bank) of any interest or other amount paid or payable by the
purchasing Bank in respect of the total amount so recovered. Borrower agrees
that any Bank so purchasing a participation from another Bank pursuant to this
Section 2.5.2 may, to the fullest extent permitted by law, exercise all its
rights of payment (including the right of setoff) with respect to such
participation as fully as if such Bank were the direct creditor of Borrower in
the amount of such participation.

     2.6 Change of Circumstances.

                                       16
<PAGE>   29

         2.6.1 Inability to Determine Rates. If, on or before the Interest Rate
Determination Date for any LIBOR Loans, (a) Administrative Agent determines
(which determination shall be conclusive absent manifest error) that the LIBO
Rate for such Interest Period cannot be adequately and reasonably determined due
to the unavailability of funds in or other circumstances affecting the London
interbank market, or (b) Banks holding aggregate Proportionate Shares of 33-1/3%
or more of the Total Loan Commitment shall advise Administrative Agent that (i)
the rates of interest for such LIBOR Loans do not adequately and fairly reflect
the cost to such Banks of making or maintaining such Loans or (ii) deposits in
Dollars in the London interbank market are not available to such Banks (as
conclusively certified by each such Bank in good faith in writing to
Administrative Agent and to Borrower) in the ordinary course of business in
sufficient amounts to make and/or maintain their LIBOR Loans, Administrative
Agent shall immediately give notice of such condition to Borrower and Banks by
telephone or telecopy. After the giving of any such notice and until
Administrative Agent shall otherwise notify Borrower and Banks that the
circumstances giving rise to such condition no longer exist, Borrower's right to
request the making of or conversion to, and Banks' obligations to make or
convert to LIBOR Loans shall be suspended. Any LIBOR Loans outstanding at the
commencement of any such suspension shall be converted at the end of the then
current Interest Period for such Loans into Base Rate Loans unless such
suspension has then ended.

         2.6.2 Illegality. If, after the date of this Agreement, the adoption of
any Governmental Rule, any change in any Governmental Rule or the application or
requirements thereof (whether such change occurs in accordance with the terms of
such Governmental Rule as enacted, as a result of amendment, or otherwise), any
change in the interpretation or administration of any Governmental Rule by any
Governmental Authority, or compliance by any Bank or Borrower with any request
or directive (whether or not having the force of law) of any Governmental
Authority (a "Change of Law") shall make it unlawful or impossible for any Bank
to make or maintain any LIBOR Loan, such Bank shall immediately notify
Administrative Agent and Borrower of such Change of Law. Upon receipt of such
notice, (a) Borrower's right to request the making of or conversion to, and such
Bank's obligations to make or convert to, LIBOR Loans shall be suspended for so
long as such condition shall exist, and (b) Borrower shall, at the request of
such Bank, either (i) pursuant to Section 2.1.7, convert any then outstanding
LIBOR Loans into Base Rate Loans at the end of the current Interest Periods for
such Loans, or (ii) immediately repay such Loans pursuant to Section 2.1.8 or
convert LIBOR Loans of the affected Type into Base Rate Loans if such Bank shall
notify Borrower that such Bank may not lawfully continue to fund and maintain
such Loans. Any conversion or prepayment of LIBOR Loans made pursuant to the
preceding sentence prior to the last day of an Interest Period for such Loans
shall be deemed a prepayment thereof for purposes of Section 2.7.

         2.6.3 Increased Costs. If, after the date of this Agreement, any Change
of Law:

               (a) Shall subject any Bank to any tax, duty or other charge with
respect to any LIBOR Loan or Commitment, or shall change the basis of taxation
of payments by Borrower to any Bank on such a Loan or with respect to any
Commitment (except for Taxes, Other Taxes or changes in the rate of taxation on
the overall net income of any Bank); or

               (b) Shall impose, modify or hold applicable any reserve, special
deposit or similar requirement (without duplication of any reserve requirement
included within

                                       17
<PAGE>   30

the applicable Interest Rate through the definition of "Reserve Requirement")
against assets held by, deposits or other liabilities in or for the account of,
advances or loans by, or any other acquisition of funds by any Bank for any
LIBOR Loan; or

               (c) Shall impose on any Bank any other condition directly related
to any LIBOR Loan or Commitment;

and the effect of any of the foregoing is to increase the cost to such Bank of
making, issuing, creating, renewing, participating in (subject to the
limitations in Section 9.13) or maintaining any such LIBOR Loan or Commitment or
to reduce any amount receivable by such Bank hereunder; then Borrower shall from
time to time, upon demand by such Bank, pay to such Bank additional amounts
sufficient to reimburse such Bank for such increased costs or to compensate such
Bank for such reduced amounts. A certificate setting forth in reasonable detail
the amount of such increased costs or reduced amounts and the basis for
determination of such amount, submitted by such Bank to Borrower, shall, in the
absence of manifest error, be conclusive and binding on Borrower for purposes of
this Agreement.

         2.6.4 Capital Requirements. If any Bank determines that (a) any Change
of Law after the date of this Agreement increases the amount of capital required
or expected to be maintained by such Bank (or the Lending Office of such Bank)
or any Person controlling such Bank (a "Capital Adequacy Requirement") and (b)
the amount of capital maintained by such Bank or such Person which is
attributable to or based upon the Loans, the Commitments or this Agreement must
be increased as a result of such Capital Adequacy Requirement (taking into
account such Bank's or such Person's policies with respect to capital adequacy),
Borrower shall pay to Administrative Agent on behalf of such Bank or such
Person, upon demand of Administrative Agent on behalf of such Bank or such
Person, such amounts as such Bank or such Person shall reasonably determine are
necessary to compensate such Bank or such Person for the increased costs to such
Bank or such Person of such increased capital. A certificate of such Bank or
such Person, setting forth in reasonable detail the computation of any such
increased costs, delivered to Borrower by Administrative Agent on behalf of such
Bank or such Person shall, in the absence of manifest error, be conclusive and
binding on Borrower for purposes of this Agreement.

         2.6.5 Notice; Participating Banks' Rights. Each Bank will notify
Borrower of any event occurring after the date of this Agreement that will
entitle such Bank to compensation pursuant to this Section 2.6, as promptly as
practicable, and in no event later than 180 days after the principal officer of
such Bank responsible for administering this Agreement obtains knowledge
thereof; provided that any Bank's failure to notify Borrower within such 180 day
period shall not relieve Borrower of its obligation under this Section 2.6.5
with respect to claims arising prior to the end of such period, but shall
relieve Borrower of its obligations under this Section 2.6.5 with respect to the
time between the end of such period and such time as Borrower receives notice
from the indemnitee as provided herein. No Person purchasing from a Bank a
participation in any Commitment (as opposed to an assignment) shall be entitled
to any payment from or on behalf of Borrower pursuant to Section 2.6.3 or 2.6.4
which would be in excess of the applicable proportionate amount (based on the
portion of the Commitment in which such Person is participating) which would
then be payable to such Bank if such Bank had not sold a participation in that
portion of the Commitment.

         2.7 Funding Losses. If Borrower shall (a) repay or prepay any LIBOR
Loans on any day other than the last day of an Interest Period for such Loans
(whether an optional prepayment or a Mandatory Prepayment), (b) fail to borrow
any LIBOR Loans in accordance with a Notice of Borrowing delivered to
Administrative Agent (whether as a result of the failure to satisfy any
applicable conditions or otherwise), (c) fail to convert any Loans into LIBOR
Loans in accordance with a Notice of Conversion of Loan Type delivered to
Administrative Agent (whether as a result of the failure to satisfy any
applicable conditions or otherwise), (d) fail to continue a LIBOR Loan in
accordance with a Confirmation of Interest Period Selection delivered to
Administrative Agent or (e) fail to make any prepayment in accordance with any
notice of prepayment delivered to Administrative Agent, Borrower shall, upon
demand by any Bank, reimburse such Bank for all costs and losses incurred by
such Bank as a result of such repayment, prepayment or failure ("Liquidation
Costs"). Borrower understands that such costs and losses may include losses
incurred by a Bank as a result of funding and other contracts entered into by
such Bank to fund LIBOR Loans. Each Bank demanding payment under this Section
2.7 shall deliver to Borrower a certificate setting forth in reasonable detail
the basis for and the amount of costs and losses for which demand is made. Any
such certificate delivered to Borrower shall, in the absence of manifest error,
be conclusive and binding on Borrower for purposes of this Agreement.

     2.8 Alternate Office; Minimization of Costs.

         2.8.1 To the extent reasonably possible, each Bank shall designate an
alternative Lending Office with respect to its LIBOR Loans and otherwise take
any reasonable actions to reduce any liability of Borrower to any Bank under
Section 2.4.4, 2.6.3 or 2.6.4, or to avoid the unavailability of any Type of
Loans under Section 2.6.2 so long as such Bank, in its sole discretion,
determines that (a) such designation is not disadvantageous to such Bank and (b)
that such actions would eliminate or reduce any such liability. Borrower hereby
agrees to pay all reasonable costs and expenses incurred by any Bank in
connection with any such designation or actions.

         2.8.2 If and with respect to each occasion that a Bank either makes a
demand for compensation pursuant to Section 2.4.4, 2.6.3 or 2.6.4 or is unable
to fund LIBOR Loans pursuant to Section 2.6.2 or such Bank wrongfully fails to
fund a Loan, Borrower may, upon at least five Banking Days' prior irrevocable
written notice to each of such Bank and Administrative Agent, in whole
permanently replace the Commitment of such Bank; provided that Borrower shall
replace such Commitment with the Commitment of a commercial bank reasonably
satisfactory to Administrative Agent. Such replacement Bank shall upon the
effective date of replacement purchase the Obligations owed to such replaced
Bank for the aggregate amount thereof and shall thereupon for all purposes
become a "Bank" hereunder. Such notice from Borrower shall specify an effective
date for the replacement of such Bank's Commitment, which date shall not be
later than the tenth day after the day such notice is given. On the effective
date of any replacement of such Bank's Commitment pursuant to this Section
2.8.2, Borrower shall pay to Administrative Agent for the account of such Bank
(a) any fees due to such Bank to the date of such replacement, (b) accrued
interest on the principal amount of outstanding Loans held by such Bank to the
date of such replacement, and (c) the amount or amounts requested by such Bank
pursuant to each of Sections 2.4.4, 2.6.3 and 2.6.4, as applicable. Borrower
will remain liable to such replaced Bank for any Liquidation Costs that

                                       19
<PAGE>   32

such Bank may sustain or incur as a consequence of repayment of such Bank's
Loans (unless such Bank has defaulted on its obligation to fund a Loan
hereunder). Upon the effective date of repayment of any Bank's Loans and
termination of such Bank's Commitment pursuant to this Section 2.8.2, such Bank
shall cease to be a Bank hereunder. No such termination of any such Bank's
Commitment and the purchase of such Bank's Loans pursuant to this Section 2.8.2
shall affect (i) any liability or obligation of Borrower or any other Bank to
such terminated Bank which accrued on or prior to the date of such termination
or (ii) such terminated Bank's rights hereunder in respect of any such liability
or obligation.

         2.8.3 Upon written notice to Administrative Agent and Borrower, any
Bank may designate a Lending Office other than that set forth on Exhibit H
hereto (which Exhibit shall be automatically amended without further action to
give effect to such designation on the date Administrative Agent receives such
notice) and may assign all of its interests under the Credit Documents and its
Notes (if any) to such Lending Office; provided that such designation and
assignment do not at the time of such designation and assignment increase the
reasonably foreseeable liability of Borrower to such Bank under Section 2.4.4,
2.6.3, or 2.6.4 or make an Interest Rate option unavailable pursuant to Section
2.6.2.

Subject Acquisition(s) in respect of which all applicable conditions have been
satisfied (or waived in accordance with the terms hereof), unless the failure of
any condition to be satisfied with respect to any Subject Project, Approved
Project or Subject Acquisition has the effect of causing an Event of Default or
Inchoate Default to occur, in which case the requested Loan shall not be
permitted to occur until such time as the Event of Default or Inchoate Default
has been cured and the applicable conditions have been satisfied (or waived in
accordance with the terms hereof).

Turbines, Material Assets or other assets funded or acquired with the proceeds
of the Loans made hereunder.

right to effect a Development Credit Event, Working Capital Credit Event or an
Acquisition Credit Event hereunder without full compliance by Borrower with the
conditions described in this Article 3.

               (b) In the event Administrative Agent determines that an item or
items listed in a Drawdown Certificate as a Cost is not properly included in

Independent Engineer, may in its reasonable discretion cause to be made a Loan
or Loans in the amount requested in such Drawdown Certificate less the amount of
such item or items or may reduce the amount of Loans made pursuant to any
subsequent Drawdown Certificate by such amount. In the event that Borrower
prevails in any dispute as to whether such Project Costs were properly included
in such Drawdown Certificate, Loans in the amount requested but not initially
made shall forthwith be made.

     3.12 Conditions Precedent Related to Permitted IDA Financings.

               (a) The Technical Committee (and not Administrative Agent, the

Borrower's required

                                       70
<PAGE>   83

satisfaction of any condition precedent set forth in Section 3.2 or 3.5, as the
case may be, with respect to any Subject Project or Subject Acquisition, as the
case may be, which is contemplated to be constructed, maintained, operated,
owned and financed pursuant to a Permitted IDA Structure; provided that (i)
Borrower approves in writing any such supplement or modification, as the case
may be, (ii) in the reasonable opinion of the Technical Committee, any such
supplement or modification, as the case may be, is not reasonably likely to have
a Borrower Material Adverse Effect or a Project Material Adverse Effect in
respect of the relevant Project Owner, (iii) any such supplement or
modification, as the case may be, is strictly limited to the relevant Subject
Project or Subject Acquisition, as the case may be, and (iv) any such supplement
or modification, as the case may be, is being proposed, granted or agreed solely
because the Credit Documents (other than this Section 3.12) do not contemplate
the construction, maintenance, operation, ownership or financing of an Approved
Project under a Permitted IDA Structure.

               (b) In connection with the granting of any supplement or
modification pursuant to Section 3.12(a), Administrative Agent (on behalf of
Banks and upon the written direction of the Technical Committee) shall enter
into each supplemental agreement with Borrower or the other relevant Portfolio
Entities which is required to (i) supplement any of the definitions set forth in
any Credit Document (including, to the extent necessary, the definitions of
"Major Project Documents", "Major Project Participants", "Permitted Debt",
"Permitted Investment", "Permitted Liens", "Project Costs", "Project Documents",
and "Project Operating Revenues"), (ii) supplement any representation and
warranty set forth in any Credit Document (including, to the extent necessary,
Sections 3.23 and 3.25 of the relevant Project Owner Guaranty) and (iii)
supplement any covenant set forth in any Credit Document (including, to the
extent necessary, Section 5.12 and Sections 4.1, 4.9, 4.11, 4.13 and 5.13 of the
relevant Project Owner Guaranty), in each case solely because the Credit
Documents (other than this Section 3.12) do not contemplate the acquisition,
construction, maintenance, operation, ownership or financing of an Approved
Project under a Permitted IDA Structure. Each such supplemental agreement shall
be in form and substance reasonably satisfactory to the Technical Committee and
Borrower and, if entered into in compliance with this Section 3.12, shall be
deemed to satisfy the requirements of Section 9.9.

                                   ARTICLE 4.
                         REPRESENTATIONS AND WARRANTIES

     Borrower makes the following representations and warranties to and in favor
of Lead Arranger, Administrative Agent and Banks as of the Closing Date and as
of each Funding Date, in each case to the extent set forth in Article 3.

     4.1 Organization.

         4.1.1 Borrower. Borrower is a limited liability company duly
constituted, validly existing and in good standing under the laws of the State
of Delaware and is duly qualified, authorized to do business and in good
standing in each other jurisdiction where the character of its properties or the
nature of its activities makes such qualification necessary. Borrower has all
requisite power and authority to (a) own or hold under lease and operate the
property it purports to own or hold under lease, (b) carry on its business as
now being conducted

                                       71
<PAGE>   84

and as now proposed to be conducted (including all activities with respect to
the Acquisitions and the Approved Projects), (c) execute, deliver and perform
each Operative Document to which it is a party and (d) take each action as may
be necessary to consummate the transactions contemplated thereunder.

         4.1.2 Member. Member (a) is a limited liability company duly formed and
validly existing in good standing under the laws of the State of Delaware with
all requisite power and authority under the laws of the State of Delaware to
enter into the Limited Liability Company Agreement and, as the sole member of
the Borrower, to perform its obligations thereunder and to consummate the
transactions contemplated thereby, (b) is duly qualified, authorized to do
business and in good standing in each other jurisdiction where the character of
its properties or the nature of its activities makes such qualification
necessary, except where the failure to do so could reasonably be expected to
have a Borrower Material Adverse Effect and (c) has the power (i) to carry on
its business as now being conducted and as now proposed to be conducted by it,
(ii) to execute, deliver and perform each Operative Document to which it is a
party (in its individual capacity), (iii) to take all action as may be necessary
to consummate the transactions contemplated thereunder.

     4.2 Capitalization.

               (a) The equity interests in Borrower are duly authorized, validly
issued and (if applicable) fully paid and nonassessable. As of the Closing Date,
Member is the sole member of Borrower.

               (b) All of the Portfolio Entities are identified in Schedule 4.2
hereto (as such Schedule 4.2 may be supplemented from time to time by written
notice to Administrative Agent upon the creation of any new Portfolio Entity in
accordance with the terms of Section 6.5.2). The equity interests of each
Portfolio Entity are identified in Schedule 4.2 hereto (as so supplemented) and
such equity interests are duly authorized, validly issued and (if applicable),
fully paid and nonassessable. Schedule 4.2 hereto (as so supplemented)
completely and correctly sets forth the ownership of each Portfolio Entity.
Except as permitted pursuant to Sections 3.2 or 3.5 and 5.16 and 6.5.2, each
Portfolio Entity (other than Borrower) is a direct or indirect wholly-owned
Subsidiary of NRG Energy and a wholly-owned Subsidiary of Borrower or an
Affiliate Pledgor.

               (c) Except as permitted pursuant to Sections 3.2 or 3.5 and 5.16
and 6.5.2, there are no options, warrants, convertible securities or other
rights to acquire any equity interests in Borrower or any other Portfolio
Entity.

     4.3 Authorization; No Conflict. Borrower has duly authorized, executed and
delivered, or has been properly assigned, each Operative Document to which it is
a party and neither Borrower's execution and delivery thereof nor its
consummation of the transactions contemplated thereby nor its compliance with
the terms thereof (a) does or will contravene the constituent documents or any
other Legal Requirement applicable to or binding on Borrower or any of its
properties, (b) does or will contravene or result in any breach of or constitute
any default under, or result in or require the creation of any Lien (other than
Permitted Liens) upon any of its properties under, any agreement or instrument
to which Borrower is a party or by

                                       72
<PAGE>   85

which it or any of its properties may be bound or affected or (c) does or will
require the consent or approval of any Person, and with respect to any
Governmental Authority, does or will require any registration with, or notice
to, or any other action of, with or by any applicable Governmental
Instrumentality, in each case which has not already been obtained and disclosed
in writing to Administrative Agent.

     4.4 Enforceability. Each of the Credit Documents and Major Project
Documents to which Borrower is a party is a legal, valid and binding obligation
of Borrower enforceable against Borrower in accordance with its terms, except to
the extent that enforceability may be limited by applicable bankruptcy,
insolvency, moratorium, reorganization or other similar laws affecting the
enforcement of creditors' rights or by the effect of general equitable
principles (regardless of whether such enforceability is considered in a
proceeding in equity or at law). Since the Closing Date, none of the Operative
Documents to which Borrower is a party has been amended or modified except in
accordance with this Agreement.

     4.5 Compliance with Law. There are no violations by Borrower, or, to the
best knowledge of Borrower, the Member, any Affiliate Pledgor or NRG Energy, of
any Legal Requirement which could reasonably be expected to have a Borrower
Material Adverse Effect or a Project Material Adverse Effect.

     4.6 Contracts, Joint Ventures.

         4.6.1 Borrower is not party to nor is it bound by any material contract
other than the Credit Documents and Acquisition Documents to which it is a
party.

         4.6.2 Borrower is not a general partner nor is it a limited partner in
any general or limited partnership or a member in any limited liability company.

     4.7 Investment Company Act, Etc. Neither Borrower nor the Member nor any
Affiliate Pledgor is an investment company or a company controlled by an
investment company, within the meaning of the Investment Company Act of 1940, as
amended, and neither Borrower nor the Member nor any Affiliate Pledgor is or has
been determined by the Securities and Exchange Commission or any other
Governmental Authority to be subject to, or not exempt from, regulation under
PUHCA or the FPA (other than as provided by PURPA or as an Exempt Wholesale
Generator).

     4.8 ERISA. Either (a) there are no ERISA Plans or Multiemployer Plans for
any Portfolio Entity or any member of the Controlled Group or (b) (i) each
Portfolio Entity and each member of the Controlled Group have fulfilled their
obligations (if any) under the minimum funding standards of ERISA and the Code
for each ERISA Plan, (ii) each ERISA Plan or Multiemployer Plan is in compliance
in all material respects with the currently applicable provisions of ERISA and
the Code and (iii) neither any Portfolio Entity nor any Controlled Group member
has incurred any liability to the PBGC or any ERISA Plan or Multiemployer Plan
under Title IV of ERISA (other than liability for premiums due in the ordinary
course). None of any Portfolio Entity's assets constitute assets of an employee
benefit plan within the meaning of 29 CFR Section 2510.3-101.

                                       73
<PAGE>   86

     4.9 Permits. With respect to each Approved Project in the case of Sections
4.9.1 and 4.9.2, and with respect to each Funded Working Capital Asset
(including each Approved Turbine) in the case of Section 4.9.3:

         4.9.1 There are no Permits under existing law as such Approved Project
is designed that are or will become Applicable Permits other than the Applicable
Permits described in the applicable Permit Schedule. Except as disclosed
therein, each Applicable Permit listed in Part I(A) of the applicable Permit
Schedule is in full force and effect and is not subject to any current legal
proceeding or to any unsatisfied condition that could reasonably be expected to
have a Borrower Material Adverse Effect or a Project Material Adverse Effect in
respect of the relevant Project Owner, and all applicable appeal periods with
respect thereto have expired. Each Permit listed in Part II(A) of the applicable
Permit Schedule is either (1) timely obtainable at a cost consistent with the
applicable Project Budget or Annual Operating Budget, as the case may be, prior
to the time the applicable Project Owner requires such Permit and is of a type
that is routinely granted upon application and that would not normally be
obtained before contemplated by Borrower or the relevant Project Owner or (2)
able to be eliminated as an Applicable Permit through the implementation of
alternative solutions at a cost consistent with the applicable Project Budget or
Annual Operating Budget, as the case may be. No fact or circumstance exists, to
the best knowledge of Borrower, which indicates that any Permit identified in
Part II(A) of the applicable Permit Schedule shall not be timely obtainable at a
cost consistent with the applicable Project Budget or Annual Operating Budget,
as the case may be, without material difficulty or delay by the relevant Project
Owner before it becomes an Applicable Permit. Each Project Owner with respect to
an Approved Project is in compliance in all material respects with all
Applicable Permits.

         4.9.2 There are no Permits under existing law as such Approved Project
is designed that are or will become Applicable Third Party Permits other than
the Permits described in the applicable Permit Schedule (or Permits the failure
of which to obtain could not reasonably be expected to have a Borrower Material
Adverse Effect or a Project Material Adverse Effect in respect of the relevant
Project Owner). Except as disclosed therein, each Applicable Third Party Permit
listed in Part I(B) of the applicable Permit Schedule is in full force and
effect and is not subject to current legal proceeding or to any unsatisfied
condition that could reasonably be expected to have a Borrower Material Adverse
Effect or a Project Material Adverse Effect in respect of the relevant Project
Owner, and all applicable appeal periods with respect thereto have expired. No
fact or circumstance exists, to the best knowledge of Borrower, which indicates
that any Applicable Third Party Permit shall not be timely obtainable at a cost
consistent with the applicable Project Budget or Annual Operating Budget, as the
case may be, without material difficulty or delay by the applicable Major
Project Participant before it becomes an Applicable Third Party Permit. To the
best knowledge of Borrower, each Major Project Participant is in compliance in
all material respects with its respective Applicable Third Party Permits, each
other Major Project Participant possesses all licenses, franchises, patents,
copyrights, trademarks and trade names, or rights thereto necessary to perform
its duties under the Operative Documents to which it is a party, and such Person
is not in violation of any valid rights of others with respect to any of the
foregoing which could reasonably be expected to have a Borrower Material Adverse
Effect or a Project Material Adverse Effect in respect of the relevant Project
Owner.

                                       74
<PAGE>   87

         4.9.3 To the best knowledge of Borrower, each Turbine Purchase
Contractor and Material Asset Purchase Contractor possesses all material
licenses, franchises, patents, copyrights, trademarks and trade names, or rights
thereto necessary to perform its duties under each Turbine Purchase Contract and
Material Asset Purchase Contract to which it is a party, and such Turbine
Purchase Contractor and Material Asset Purchase Contractor is not in violation
of any valid rights of others with respect to any of the foregoing which could
reasonably be expected to have a Borrower Material Adverse Effect.

     4.10 Intellectual Property. Borrower owns or has the right to use all
material patents, trademarks, service marks, trade names, copyrights, licenses
and other similar rights, which are necessary for the operation of its business.
Except as set forth on Exhibit G-5 hereto, nothing has come to the attention of
Borrower to the effect that (a) any material product, process, method,
substance, part or other material presently contemplated to be sold by or
employed by Borrower in connection with its business will infringe any patent,
trademark, service mark, trade name, copyright, license or other right owned by
any other Person, (b) there is pending or threatened any claim or litigation
against or affecting Borrower contesting its right to sell or use any such
product, process, method, substance, part or other material or (c) there is, or
there is pending or proposed, any patent, invention, device, application or
principle or any statute, law, rule, regulation, standard or code relating to
the use of technology or intellectual property by Borrower, in each case which
could reasonably have a Borrower Material Adverse Effect or a Project Material
Adverse Effect.

     4.11 Hazardous Substance.

         4.11.1 Except as set forth in Exhibit G-6 hereto: (a) neither any
Portfolio Entity nor the Member nor NRG Energy (for the purposes of this
Section, the "Subject Companies"), with respect to the Sites, Improvements or
other Mortgaged Properties owned or leased by a Portfolio Entity, is or has in
the past been in violation of any Hazardous Substance Law which violation could
reasonably be expected to result in a material liability to any of the Subject
Companies or their respective properties and assets or in an inability of any
Portfolio Entity to perform its obligations under any Operative Document; (b)
none of the Subject Companies nor, to the best knowledge of Borrower, any third
party has used, released, discharged, generated, manufactured, produced, stored,
or disposed of in, on, under, or about the Sites, Improvements or other
Mortgaged Properties owned or leased by any Portfolio Entity, or transported
thereto or therefrom, any Hazardous Substances that could reasonably be expected
to subject any Bank to liability or any Subject Company to material liability,
under any Hazardous Substance Law; (c) to the best knowledge of Borrower, there
are no underground tanks, whether operative or temporarily or permanently
closed, located on the Sites, Improvements or other Mortgaged Properties owned
or leased by any Portfolio Entity; (d) there are no Hazardous Substances used,
stored or present at, on or, to the best knowledge of Borrower, near the Sites,
Improvements or other Mortgaged Properties owned or leased by any Portfolio
Entity, except in compliance with Hazardous Substance Laws and other Legal
Requirements or as disclosed in the Environmental Reports; and (e) to the best
knowledge of Borrower, there neither is nor has been any condition,
circumstance, action, activity or event that could reasonably be expected to be
a material violation by any Subject Company of any Hazardous Substance Law, or
to result in liability to any Bank or material liability to any Subject Company
under any Hazardous Substance Law.

                                       75
<PAGE>   88

         4.11.2 Except as set forth on Exhibit G-5 hereto or Exhibit G-6 hereto,
there is no pending or, to the best knowledge of Borrower, threatened, action or
proceeding by any Governmental Authority (including the U.S. Environmental
Protection Agency) or any non-governmental third party with respect to the
presence or Release of Hazardous Substances in, on, from or to the Sites,
Improvements or other Mortgaged Properties owned or leased by any Portfolio
Entity.

         4.11.3 (a) Except as set forth on Exhibit G-5 hereto or Exhibit G-6
hereto, no Subject Company has knowledge of any past or existing violations of
any Hazardous Substances Laws by any Person relating in any way to the Sites,
Improvements or other Mortgaged Properties owned or leased by any Portfolio
Entity, in each case which could reasonably be expected to have a Borrower
Material Adverse Effect or a Project Material Adverse Effect.

     4.12 Litigation.

               (a) As of the Closing Date, except as set forth on Exhibit G-5
hereto, there are no pending or, to the best knowledge of Borrower, threatened
actions or proceedings of any kind, including actions or proceedings of or
before any Governmental Authority, to which Borrower, any Affiliate Pledgor or
the Member or an Identified Project, Approved Project or Acquisition Plant is a
party or is subject, or by which any of them or any of their properties or an
Identified Project, Approved Project or Acquisition Plant are bound.

               (b) As of the Closing Date, except as set forth on Exhibit G-5
hereto, there are no pending or, to the best knowledge of Borrower, threatened
actions or proceedings of any kind (including actions or proceedings of or
before any Governmental Authority) to which NRG Energy or, to the best knowledge
of Borrower, any other Major Project Participants is a party or is subject, or
by which any of them or any of their properties are bound, which if adversely
determined to or against NRG Energy, the Member or any Affiliate Pledgor or any
other Major Project Participant could reasonably be expected to have a Sponsor
Material Adverse Effect or a Borrower Material Adverse Effect.

               (c) After the Closing Date, there are no pending or, to the best
knowledge of Borrower, threatened actions or proceedings of any kind, including
actions or proceedings of or before any Governmental Authority, to which
Borrower, the Member, any Affiliate Pledgor or NRG Energy is a party or is
subject, or by which any of them or any of their properties are bound which have
not been disclosed by Borrower to Administrative Agent in accordance with, and
to the extent required by, Section 5.3.

     4.13 Labor Disputes and Acts of God. Neither the business nor the
properties of Borrower, the Member, any Affiliate Pledgor or NRG Energy, or, to
the best knowledge of Borrower, any other Major Project Participant are affected
by any fire, explosion, accident, strike, lockout or other labor dispute,
drought, storm, hail, earthquake, embargo, act of God or of the public enemy, or
other casualty (whether or not covered by insurance), which could reasonably be
expected to have a Borrower Material Adverse Effect.

     4.14 Project Documents. Except as permitted by Section 3.2.6(t) or
3.5.7(u), copies of all of the Project Documents and Turbine Purchase Contracts
and Material Asset Purchase

                                       76
<PAGE>   89

Contracts in effect with respect to the Approved Projects, Funded Working
Capital Assets and Acquisitions, as the case may be, as of such date have been
delivered to Administrative Agent by Borrower.

     4.15 Disclosure. Neither this Agreement nor any certificate or other
documentation (other than the Project Budgets, the Annual Operating Budgets, the
Maintenance Budgets and the Base Case Project Projections) furnished to
Administrative Agent, the Lead Arranger or the Technical Committee, or to any
consultant submitting a report to Administrative Agent, the Lead Arranger or the
Technical Committee, by or, to the best knowledge of Borrower, on behalf of NRG
Energy or the Member in connection with the transactions contemplated by this
Agreement or the Project Documents or the design, description, testing or
operation of an Acquisition, Approved Project or an Approved Turbine, contains
any untrue statement of a material fact or omits to state a material fact
necessary in order to make the statements contained herein or therein not
misleading under the circumstances in which they were made at the time such
statements are made. As of the Closing Date, there is no fact known to Borrower
which has had or could reasonably be expected to have a Borrower Material
Adverse Effect or a Project Material Adverse Effect which has not been set forth
in this Agreement or in the other documents, certificates and written statements
furnished to Administrative Agent and/or the Independent Consultants, by or on
behalf of Borrower in connection with the transactions contemplated hereby.

     4.16 Private Offering by Borrower. Assuming that Banks are acquiring the
Notes for investment purposes only, and not for purposes of resale or
distribution thereof except for assignments or participations as provided in
Sections 9.13 and 9.14, no registration of the Notes under the Securities Act of
1933, as amended, or under the securities laws of the State of New York, or any
other state in which an Approved Project, Funding Working Capital Asset or
Acquisition is located is required in connection with the offering, issuance and
sale of the Notes hereunder. Neither Borrower nor anyone acting on its behalf
has taken, or will take, any action which would subject the issuance or sale of
the Notes to Section 5 of the Securities Act of 1933, as amended.

     4.17 Taxes. All tax returns and reports of the Member, each Affiliate
Pledgor and Borrower required to be filed by any such Person have been timely
filed, and all taxes required to be paid with respect to such tax returns to be
due and payable and all material assessments, utility charges, fees and other
governmental charges upon the Member, each Affiliate Pledgor and Borrower and
upon their respective properties, assets, income, businesses and franchises
which are due and payable have been paid when due and payable, other than those
taxes, assessments, fees and charges being contested in good faith and by
appropriate proceedings and for which reserves or other appropriate provisions,
if any, as shall be required in conformity with GAAP shall have been made or
provided therefor. Borrower knows of no proposed tax assessment against NRG
Energy, the Member, Borrower, any Affiliate Pledgor or any Portfolio Entity
which could reasonably be expected to have a Borrower Material Adverse Effect
that is not being actively contested by such Person in good faith and by
appropriate proceedings and for which reserves or other appropriate provisions,
if any, as shall be required in conformity with GAAP shall not have been made or
provided therefor. For federal income tax purposes, Borrower is a limited
liability company and not an association taxed as a corporation.

                                       77
<PAGE>   90

     4.18 Governmental Regulation. Except to the extent that the FPA or PUHCA is
applicable to Borrower solely by reason of Borrower being an Exempt Wholesale
Generator or the owner of a Qualifying Facility, none of Borrower, the Member,
any Affiliate Pledgor, Administrative Agent, or any Bank, nor any Affiliate of
any of them will, solely as a result of the construction, ownership, leasing or
operation of any Identified Project or Non-Identified Project or any Turbine,
the sale of electricity, capacity or ancillary services therefrom or the
entering into any Operative Document or any transaction contemplated hereby or
thereby, be subject to, or not exempt from, regulation under the FPA or PUHCA or
under state laws and regulations respecting the rates or the financial or
organizational regulation of electric utilities. Borrower is not subject to
regulation under any Governmental Rule as to securities, rates or financial or
organizational matters that would preclude the making or repayment of any Loans,
or the incurrence by Borrower of any of the Obligations or the execution,
delivery and performance by Borrower of the Operative Documents to which it is a
party. Borrower will not be deemed by any Governmental Authority having
jurisdiction to be subject to financial, organizational or rate regulation as an
"electric utility," "electric corporation," "electrical company," "public
utility," "public utility holding company" or any similar Person under any
existing law, rule or regulation of any Governmental Authority.

     4.19 Margin Stock. Borrower is not engaged principally, or as one of its
principal activities, in the business of extending credit for the purpose of
"buying", "carrying" or "purchasing" margin stock (as defined in Regulations T,
U or X of the Federal Reserve Board), and no part of the proceeds of the Loans
or the Project Revenues or the proceeds of any loans made under any Intercompany
Loan Agreement will be used by Borrower to buy, carry or purchase any such
margin stock or to extend credit to others for the purpose of "buying",
"carrying" or "purchasing" any such margin stock or for any other purpose which
violates the provisions of the regulations of the Federal Reserve Board.

     4.20 Budgets; Projections. Borrower has prepared the Project Budgets, the
Annual Operating Budgets, the Maintenance Budgets (to the extent applicable) and
the Base Case Project Projections and is responsible for developing the
assumptions on which the Project Budgets, the Annual Operating Budgets, the
Maintenance Budgets (to the extent applicable) and the Base Case Project
Projections are based; and the Project Budgets, the Annual Operating Budgets,
the Maintenance Budgets (to the extent applicable) and the Base Case Project
Projections for the Identified Projects, the Approved Projects and Acquisitions
(a) as of the date delivered, updated or supplemented are based on reasonable
assumptions (including as to all legal and factual matters material to the
estimates set forth therein), (b) as of the date delivered, updated or
supplemented are consistent with the provisions of the Project Documents in
effect as of such date and (c) as of the date delivered, updated or supplemented
indicate that the estimated Project Costs with respect to such Project or
Acquisition, as the case may be, will not exceed funds available (including
Committed Equity Funds) to pay Project Costs with respect to such Project or
Acquisition, as the case may be. In the reasonable opinion of Borrower, as of
the date delivered, updated or supplemented, the textual material accompanying
the Base Case Project Projections for the Identified Projects, the Approved
Projects and Acquisitions discloses all information reasonably necessary for an
understanding of the Base Case Project Projections, and does not contain any
material misstatements or omit any information which, in conjunction with other
information given, would be necessary to make such information not materially
misleading. Lead Arranger, Arrangers, the Technical Committee and Banks
acknowledge that

                                       78
<PAGE>   91

the Project Budgets, the Annual Operating Budgets, the Maintenance Budgets (to
the extent applicable) and the Base Case Project Projections, in so far as the
Project Budgets, the Annual Operating Budgets, the Maintenance Budgets (to the
extent applicable) and the Base Case Project Projections relate to future
events, cannot be viewed as fact and that actual results during the period or
periods specified therein may differ from the budgeted or projected results set
forth therein.

     4.21 Financial Statements. In the case of each financial statement and
accompanying information delivered by Borrower hereunder (including financial
statements of the Portfolio Entities, NRG Energy, the Member, any Affiliate
Pledgor and any Affiliated Major Project Participants delivered pursuant to
Sections 3.1.14, 3.2.19, 3.5.20 and 5.4, but excluding any financial statements
of any Major Project Participant which is not an Affiliate of NRG Energy), each
such financial statement and information shall have been prepared in conformity
with GAAP and fairly present, in all material respects, the financial position
(on a consolidated and, where applicable, consolidating basis) of the Persons
described in such financial statements as at the respective dates thereof and
the results of operations and cash flows (on a consolidated and, where
applicable, consolidating basis) of the Persons described therein for each of
the periods then ended, subject, in the case of any such unaudited financial
statements, to changes resulting from audit and normal year-end adjustments.
Except for obligations under the Operative Documents to which it is a party,
Borrower does not (and will not following the funding of the initial Loans) have
any contingent obligations, unmatured liabilities, contingent liability or
liability for taxes, long-term lease or forward or long-term commitment that is
not reflected in the foregoing financial statements or the notes thereto and
which in any such case is material in relation to the business, operations,
properties, assets, financial condition or prospects of Borrower and the other
Portfolio Entities taken as a whole.

     4.22 Existing Defaults. Borrower is not in default under any material term
of any Operative Document relating to the Approved Projects, the Funded Working
Capital Assets or the Acquisitions or any agreement relating to any obligation
of Borrower for or with respect to borrowed money. To the best knowledge of
Borrower, no other party to any Operative Document is in default thereunder,
which default could reasonably be expected to have a Borrower Material Adverse
Effect.

     4.23 Offices, Location of Collateral.

     4.23.1 The chief executive office or chief place of business (as such term
is used in Article 9 of the Uniform Commercial Code as in effect in each state
where the Collateral is located and the State of New York from time to time) of
Borrower and each Portfolio Entity is set forth in Schedule 4.23 hereto (as such
schedule may be supplemented from time to time by 30 days' notice to
Administrative Agent pursuant to Section 6.15). Borrower's federal employer
identification number is 41-1006241 and each of the other Portfolio Entities'
federal employer numbers are set forth in Schedule 4.23 hereto (as so
supplemented) or as otherwise delivered to Administrative Agent in connection
with the satisfaction of the requirements for initial funding of Development
Loans or Working Capital Loans under Section 3.2, 3.4 or 3.5, as the case may
be.

                                       79
<PAGE>   92

     4.23.2 With respect to each Approved Project, Funded Working Capital Asset
or Acquisition, all of the tangible Collateral (other than the Accounts,
Mortgaged Properties and general intangibles) related thereto, is, or when
acquired or installed pursuant to the Project Documents will be, located in a
jurisdiction where a properly completed financing statement has been filed with
the appropriate filing office for the creation of a security interest therein or
at the address set forth in Schedule 4.23 hereto (as such schedule may be
supplemented from time to time by 30 days' notice to Administrative Agent).

         4.23.3 The location of Borrower's books of accounts and records is set
forth in Schedule 4.23 hereto (as such schedule may be supplemented from time to
time by 30 days' notice to Administrative Agent).

     4.24 Title and Liens.

               (a) With respect to the properties and assets attributable to the
Initial Contribution, Borrower with respect to such properties and assets has
good, and with respect to real property, marketable and insurable title to such
properties and assets, in each case free and clear of all Liens, encumbrances or
other exceptions to title other than Permitted Liens.

               (b) Except as contemplated by Sections 3.2 or 3.5 and 5.16, (i)
each Project Owner is a direct or indirect wholly-owned Subsidiary of NRG Energy
and (A) Borrower or (B) an Affiliate Pledgor, (ii) each Project Owner owns 100%
of its respective Identified Project or Non-Identified Project and (iii) each
Project Owner holds title to only one Identified Project or Non-Identified
Project or one Approved Turbine and any Funded Working Capital Assets related
thereto.

               (c) The Lien of the Collateral Documents constitutes a valid lien
on all Collateral comprising the Initial Contribution. The Lien of the
Collateral Documents constitutes a first priority perfected security interest in
all the personal property relating to the Initial Contribution, subject to no
Liens except (i) Permitted Liens described in clauses (a), (b) and (e) of the
definition thereof and (ii) to the extent required by Governmental Rule, clauses
(c) and (g) of the definition of "Permitted Liens".

               (d) The Lien of the Collateral Documents (to the extent then
existing) constitutes a valid lien on all Collateral relating to the Approved
Projects, the Funded Working Capital Assets and any other asset (including any
Acquisition Plants) acquired with the proceeds of any Loan. The Lien of the
Collateral Documents (to the extent then existing) constitutes a valid and
subsisting first priority Lien of record on all the Mortgaged Properties
relating to the Approved Projects and Acquisition Plants described in the Deeds
of Trust or Mortgages, as the case may be (to the extent required pursuant to
Article 3 and Section 5.12.3), and, a first priority perfected security interest
in all the personal property relating to the Approved Projects, the Funded
Working Capital Assets and the other assets described in the Collateral
Documents, subject to no Liens except (i) Permitted Liens described in clauses
(a), (b) and (e) of the definition thereof, (ii) to the extent required by
Governmental Rule, clauses (c) and (g) of the definition of "Permitted Liens"
and (iii) Permitted Encumbrances.

     4.25 Collateral. The security interests granted to Administrative Agent,
for the benefit of Secured Parties, pursuant to the Collateral Documents in the
Collateral related to the Initial Contribution, the Approved Projects, the
Funded Working Capital Assets and the other assets described in such Collateral
Documents (a) constitute as to personal property included in the Collateral and,
with respect to subsequently acquired personal property included in the
Collateral, will constitute, a perfected security interest under the UCC to the
extent a security interest can be perfected by filing or, in the case of the
Accounts, and the Pledged Equity Interests (the Pledged Equity Interests being
"certificated securities" as defined in Article 8 of the UCC), by possession by
or on behalf of the secured party and (b) are, and, with respect to such
subsequently acquired personal property, will be, as to Collateral related to
the Initial Contribution, the Approved Projects, the Funded Working Capital
Assets and the other assets described in such Collateral Documents perfected
under the UCC as aforesaid, superior and prior to the rights of all third
Persons now existing or hereafter arising whether by way of mortgage, lien,
security interests, encumbrance, assignment or otherwise. Except to the extent
possession of portions of such Collateral is required for perfection, all such
action as is necessary has been taken to establish and perfect Administrative
Agent's, for the benefit of Secured Parties, rights in and to such Collateral to
the extent Administrative Agent's, for the benefit of Secured Parties, security
interest can be perfected by filing, including any recording, filing,
registration, giving of notice or other similar action. No filing, recordation,
re-filing or re-recording other than those listed on Exhibit D-5 hereto (as the
same may be supplemented pursuant to Article 3 from time to time) is necessary
to perfect and maintain the perfection of the interest, title or Liens of the
Collateral Documents related to the Initial Contribution, the Approved Projects,
the Funded Working Capital Assets and the other assets described in such
Collateral Documents, and all such filings or recordings will have been made to
the extent Administrative Agent's, for the benefit of Secured Parties, security
interest can be perfected by filing. The Member, each Affiliate Pledgor and each
Portfolio Entity has properly delivered or caused to be delivered to
Administrative Agent all such Collateral that requires perfection of the Lien
and security interest described above by possession.

                                   ARTICLE 5.
                        AFFIRMATIVE COVENANTS OF BORROWER

     Borrower covenants and agrees that, so long as any of the Commitments shall
remain in effect and until payment and performance in full of all of the Loans
and Obligations, Borrower will perform, and, to the extent specified below, will
cause each of the other Portfolio Entities, all covenants set forth in this
Article 5.

     5.1 Use of Proceeds and Revenues.

         5.1.1 Proceeds. Unless otherwise applied by Administrative Agent
pursuant to this Agreement, Borrower shall (a) deposit the proceeds of the Loans

Owner which is not a Subsidiary of Borrower pursuant to an Intercompany Loan
Agreement (Borrower), provided

                                       81
<PAGE>   94

Working Capital Loans shall only be used (i) by Borrower and Project Owners,
(ii) for working capital purposes in respect of any Approved Project which has
achieved Provisional Acceptance and (iii) to make progress payments in respect
of, or to otherwise acquire, any Approved Turbine. Notwithstanding anything to
the contrary herein (but subject to Section 6.6), Borrower may also use the
proceeds of any Loan advanced hereunder to fund one or more Restricted Payments
to the Member, any Affiliate Pledgor or NRG Energy, provided that the aggregate
amount of such Restricted Payments shall not exceed the aggregate amount of
Contributions made by the Member, any Affiliate Pledgor or NRG Energy to
Borrower in accordance with Section 3.9 (exclusive of any such Contributions
which were made (A) for the purpose of providing Borrower with sufficient
Available Development Funds to cause the timely Completion of the Approved

contemplated by Section 2.1.8(c)).

asset acquired with the proceeds of a Loan, unless otherwise applied by
Administrative Agent pursuant to Article 7 and the terms of the Depositary
Agreement, Borrower shall (a) deposit all Project Revenues received by or due to
Borrower (other than Insurance Proceeds, Eminent Domain Proceeds and damage

to Completion of such Approved Project in the relevant Development Sub-Account
for application toward Project Costs and otherwise for application as set forth
in Section 2.1.3 of the Depositary Agreement, (b) deposit all Project Revenues
received by or due to Borrower (other than Insurance Proceeds, Eminent Domain
Proceeds and damage payments described in Sections 2.1.2, 2.3 and 2.7 of the
Depositary Agreement) received after Completion of such Approved Project in the
Revenue Account for application solely for the purposes and in the order and
manner provided in Section 2.2.3 of the Depositary Agreement, (c) deposit all
Insurance Proceeds and Eminent Domain Proceeds described in Section 2.3.2 of the

application solely for the purposes, and in the order and manner, provided in
Sections 2.3.3, 2.3.4 and 2.3.5 of the Depositary Agreement and (d) deposit all
proceeds received by Borrower pursuant to an Intercompany Loan Agreement

the case of NRG Energy, $25,000,000) the aggregate per year, (b) injunctive or
declaratory relief, or (c) any Liens (other than Permitted Liens) relating to an
Approved Project, Acquisition Plant or a Funded Working Capital Asset for taxes

Material Adverse Effect;

         5.3.7 Any act by Borrower to become a surety, guarantor, endorser or
accommodation endorser for a third party other than endorsement of negotiable
instruments for collection purposes or Permitted Debt;

         5.3.8 Promptly, but in no event later than 30 days prior to the time
any Person will become an equity holder of Borrower or the occurrence of any
other change in or transfer of ownership interests in Borrower notice thereof,
which notice shall identify such Person and such Person's interest in Borrower
and shall describe, in reasonable detail, such other change or transfer;

         5.3.9 Any material notices delivered to or received from any Person
(other than a Portfolio Entity) under any Project Document relating to an
Approved Project, an Approved Turbine or an Acquisition Document.

Energy, the Member or Borrower, or any credit rating assigned to the Loans and
transactions contemplated hereby.

     5.9 Calculation of Ratios.

         5.9.1 For purposes of this Agreement (including Article 3 and Sections

Document, Borrower shall, and shall cause each Portfolio Entity to, calculate
the Deemed Debt Service Coverage Ratios, the Historical Debt Service Coverage
Ratios, the Projected Debt Service Coverage Ratios and the Interest Coverage
Ratios (a) without taking into account the EBITDA and Project Revenues produced
by an Approved Project in respect of which a Project Default or Project Inchoate

consistent with and supported by the conclusions set forth in the most recently
delivered Independent Consultants' reports and (c) with respect to any
calculation of a Deemed Debt Service Coverage Ratio, in a manner which is

         5.9.2 (a) In connection with the making of an initial Development Loan
for a Subject Project or a Subject Acquisition or the release of the Liens of
the Collateral Documents in respect of an Approved Project, Borrower shall
deliver a properly completed Ratio Election Certificate, in substantially the

non-recourse loans to capitalization (the "Applicable Development Loan Ratio")
for (i) with respect to any elections made pursuant to Section 3.2.28, the
relevant Subject Project and all Approved Projects, (ii) with respect to any
elections made pursuant to Section 3.5.27, the relevant Subject Acquisition and
all Approved Projects and (iii) with respect to any elections made pursuant to
Section 6.4.2(a)(iii), all Approved Projects (other than the Approved Project
which is proposed to be released). Such elected Applicable Development Loan
Ratio shall be equal to or lower than the Deemed Development Loan Ratio in
effect immediately after giving effect to the proposed initial funding or
release, as the case may be.

               (b) Without limiting anything set forth in clause (a) above, with
respect to any Subject Project or Approved Project which was initially funded
after the satisfaction of the conditions precedent set forth in Section 3.2 and
(in each case) which is an Identified Project, Borrower may elect any such
Applicable Development Loan Ratio only if it demonstrates to the reasonable
satisfaction of the Technical Committee that (as of such initial funding date or
release date, as the case may be and based in part on the proposed Applicable
Development Loan Ratios) the minimum and average projected annual Deemed Debt
Service Coverage Ratios for such Subject Project or such Approved Project, as
the case may be, satisfy the requirements set forth in Section 3.2.21(c).

               (c) Without limiting anything set forth in clause (a) or (b)
above, with respect to any Subject Project or Approved Project which was
initially funded after the satisfaction of the conditions precedent set forth in
Section 3.2 and (in each case) which is a Non-Identified Project, Borrower may
elect any such Applicable Development Loan Ratio only if it demonstrates to the
reasonable satisfaction of the Technical Committee that (as of such initial
funding date or release date, as the case may be and based in part on the
proposed Applicable Development Loan Ratios) the minimum and average projected
annual Deemed Debt

                                       86
<PAGE>   99

Service Coverage Ratios for such Subject Project or such Approved Project, as
the case may be, satisfy the requirements set forth in 3.2.21(d).

               (d) Without limiting anything set forth in clause (a), (b) or (c)
above, with respect to any Subject Acquisition or Approved Project which was
initially funded after the satisfaction of the conditions precedent set forth in
Section 3.5, Borrower may elect any such Applicable Development Loan Ratio only
if it demonstrates to the reasonable satisfaction of the Technical Committee
that (as of such initial funding date or release date, as the case may be and
based in part on the proposed Applicable Development Loan Ratios) the minimum
and average projected annual Deemed Debt Service Coverage Ratios for such
Subject Acquisition or such Approved Project, as the case may be, satisfy the
requirements set forth in 3.5.22(c).

     5.10 Indemnification.

         5.10.1 Borrower shall, and shall cause each other Portfolio Entity to,
indemnify, defend and hold harmless Lead Arranger, Arrangers, Administrative
Agent, each member of the Technical Committee and each Bank, and in their
capacities as such, their respective officers, directors, shareholders,
controlling Persons, employees, agents and servants (collectively, the
"Indemnitees") from and against and reimburse the Indemnitees for:

               (a) any and all claims, obligations, liabilities, losses,
damages, injuries (to Person, property, or natural resources), penalties, stamp
or other similar taxes, actions, suits, judgments, costs and expenses (including
reasonable attorney's fees) of whatever kind or nature, whether or not well
founded, meritorious or unmeritorious, demanded, asserted or claimed against any
such Indemnitee (collectively, "Subject Claims") in any way relating to, or
arising out of or in connection with this Agreement, the other Operative
Documents, any Identified Project or Non-Identified Project, any Acquisition,
any Approved Project or any Funded Working Capital Asset, except for claims by a
Portfolio Entity against an Indemnitee that are in whole or in part successful;

               (b) any and all Subject Claims arising in connection with the
release or presence of any Hazardous Substances at any Identified Project,
Non-Identified Project and Approved Project, whether foreseeable or
unforeseeable, including all costs of removal and disposal of such Hazardous
Substances, all reasonable costs required to be incurred in (i) determining
whether any Identified Project, Non-Identified Project and Approved Project is
in compliance and (ii) causing each Identified Project, Non-Identified Project
and Approved Project to be in compliance, with all applicable Legal
Requirements, all reasonable costs associated with claims for damages to Persons
or property, and reasonable attorneys' and consultants' fees and court costs;
and

               (c) any and all Subject Claims in any way relating to, or arising
out of or in connection with any claims, suits, liabilities against any
Portfolio Entity, the Member, NRG Energy or any of their Affiliates.

         5.10.2 The foregoing indemnities shall not apply with respect to an
Indemnitee, to the extent arising as a result of the gross negligence or willful
misconduct of such Indemnitee, but shall continue to apply to other Indemnitees.

                                       87
<PAGE>   100

         5.10.3 The provisions of this Section 5.10 shall survive foreclosure of
the Collateral Documents and satisfaction or discharge of the Portfolio Entities
obligations hereunder and under the other Credit Documents, and shall be in
addition to any other rights and remedies of Lead Arranger, Arrangers, the
Technical Committee, Administrative Agent and any Bank.

         5.10.4 In case any action, suit or proceeding shall be brought against
any Indemnitee, such Indemnitee shall notify Borrower of the commencement
thereof, and Borrower shall be entitled, at its expense, acting through counsel
reasonably acceptable to such Indemnitee, to participate in, and, to the extent
that Borrower desires, to assume and control the defense thereof. Such
Indemnitee shall be entitled, at its expense, to participate in any action, suit
or proceeding the defense of which has been assumed by Borrower. Notwithstanding
the foregoing, Borrower shall not be entitled to assume and control the defenses
of any such action, suit or proceedings if and to the extent that, in the
reasonable opinion of such Indemnitee and its counsel, such action, suit or
proceeding involves the potential imposition of criminal liability upon such
Indemnitee or a conflict of interest between such Indemnitee and Borrower or
between such Indemnitee and another Indemnitee (unless such conflict of interest
is waived in writing by the affected Indemnitees), and in such event (other than
with respect to disputes between such Indemnitee and another Indemnitee)
Borrower shall pay the reasonable expenses of such Indemnitee in such defense.

         5.10.5 Borrower shall report to such Indemnitee on the status of such
action, suit or proceeding as material developments shall occur and from time to
time as requested by such Indemnitee (but not more frequently than every 60
days). Borrower shall deliver to such Indemnitee a copy of each document filed
or served on any party in such action, suit or proceeding, and each material
document which Borrower possesses relating to such action, suit or proceeding.

         5.10.6 (a) Notwithstanding Borrower's rights hereunder to control
certain actions, suits or proceedings, if any Indemnitee reasonably determines
that failure to compromise or settle any Subject Claim made against such
Indemnitee is reasonably likely to have an imminent material adverse effect on
such Indemnitee or a Borrower Material Adverse Effect, such Indemnitee shall be
entitled (and Borrower shall cause other relevant Portfolio Entity to agree to
the same) to compromise or settle such Subject Claim.

               (b) Notwithstanding Borrower's rights hereunder to control
certain actions, suits or proceedings, if the Required Banks reasonably
determine that failure to compromise or settle any Subject Claim made against
such Indemnitee is reasonably likely to have an imminent Borrower Material
Adverse Effect or a Project Material Adverse Effect, such Indemnitee or the
Required Banks, as the case may be, shall provide Borrower with written notice
of a proposed compromise or settlement of such claim specifying in detail the
nature and amount of such proposed settlement or compromise. Borrower (and any
other relevant Portfolio Entity) shall be deemed to have approved such proposed
compromise or settlement unless, within 30 days after the date Borrower receives
such notice of intended compromise or settlement, Borrower provides such
Indemnitee or the Required Banks, as the case may be, with (i) a written legal
analysis from counsel reasonably acceptable to such Indemnitee or Required
Banks, as the case may be, reasonably concluding that, based on the magnitude of
the Subject

                                       88
<PAGE>   101

Claim, the legal basis for such Subject Claim, and/or the cost of defending such
Subject Claim, the amount of such proposed settlement or compromise is not
within a reasonable range of settlements or compromises for such Subject Claim,
and indicating, based on such factors, such counsel's view as to the appropriate
amount of a reasonable settlement or compromise for such Subject Claim (the
"Settlement Amount"). If the Indemnitee or the Required Banks, as the case may
be, receives such legal analysis required by this Section within such 30-day
period, the Indemnitee or the Required Banks, as the case may be, may elect to
settle or compromise such Subject Claim and Borrower shall be responsible for
the payment of all amounts of such compromise or settlement up to 125% of the
Settlement Amount, such Indemnitee shall be responsible for payment of all
amounts of such compromise or settlement in excess of such 125% limit and such
compromise or settlement shall be binding upon Borrower. If Borrower does not
provide such legal analysis within such period, or if such legal analysis is not
reasonable, in the reasonable determination of such Indemnitee or the Required
Banks, as the case may be, such Indemnitee may settle or compromise such Subject
Claim (and Borrower shall cause any other relevant Portfolio Entity to agree to
the same) and shall be fully indemnified by Borrower therefor. Such Indemnitee
or the Required Banks, as the case may be, shall not otherwise settle or
compromise any such Subject Claim other than at its own expense.

         5.10.7 Upon payment of any Subject Claim by Borrower pursuant to this
Section 5.10 or other similar indemnity provisions contained herein to or on
behalf of an Indemnitee, Borrower, without any further action, shall be
subrogated to any and all claims that such Indemnitee may have relating thereto,
and such Indemnitee shall cooperate with Borrower and give such further
assurances as are necessary or advisable to enable Borrower vigorously to pursue
such claims.

         5.10.8 Any amounts payable by Borrower pursuant to this Section 5.10
shall be regularly payable within 30 days after Borrower receives an invoice for
such amounts from any applicable Indemnitee, and if not paid within such 30-day
period shall bear interest at the Default Rate.

         5.10.9 Notwithstanding anything to the contrary set forth herein,
Borrower shall not, in connection with any one legal proceeding or claim, or
separate but related proceedings or claims arising out of the same general
allegations or circumstances, in which the interests of the Indemnitees do not
materially differ, be liable to the Indemnitees (or any of them) under any of
the provisions set forth in this Section 5.10 for the fees and expenses of more
than one separate firm of attorneys (which firm shall be selected by the
affected Indemnitees, or upon failure to so select, by Administrative Agent).

         5.10.10 If, for any reason whatsoever, the indemnification provided
under this Section 5.10 is unavailable to any Indemnitee or is insufficient to
hold it harmless to the extent provided in this Section 5.10, then provided such
payment is not prohibited by or contrary to any applicable Governmental Rule,
Legal Requirement or public policy, Borrower shall contribute to the amount paid
or payable by such Indemnitee as a result of the Subject Claim in such
proportion as is appropriate to reflect the relative economic interests of
Borrower and its Affiliates on the one hand, and such Indemnitee on the other
hand, in the matters contemplated by this Agreement as well as the relative
fault of Borrower (and its Affiliates) and such Indemnitee with respect to such
Subject Claim, and any other relevant equitable considerations.

     5.11 Operation of Approved Projects and Annual Operating Budget.

               (a) With respect to each Approved Project, on or before the date
which is 60 days prior to the first day of the month in which Completion of such
Approved Project occurs or is anticipated to occur (or, in the case of any
Approved Project which is acquired after the satisfaction of the conditions
precedent set forth in Section 3.5, on or before the date of the making of the
initial Loan hereunder in respect of such Approved Project, all as more
particularly provided for in Section 3.5.23(b)) and 60 days prior to the first
day of each year thereafter, Borrower shall submit to Administrative Agent a
draft operating plan and a budget, detailed by month for such Approved Project,
of anticipated revenues and anticipated expenditures, such budget to include
debt service (if applicable), proposed distributions, maintenance, repair and
operation expenses (including reasonable allowance for contingencies), Major
Maintenance, reserves and all other anticipated O&M Costs for such Approved
Project for the remainder of the year for the first such plan and budget and for
the ensuing year for each other such plan and budget and, in the case of Major
Maintenance, to the conclusion of the second full year thereafter (each such
annual operating plan and budget with respect to each Approved Project and for
all the Approved Projects as a whole, an "Annual Operating Budget"). Except as
otherwise provided for in Section 3.5.23(b), each Annual Operating Budget shall
be subject to the reasonable approval of Administrative Agent and the
Independent Engineer. Other than with respect to any Annual Operating Budget
delivered pursuant to Section 3.5.23(b), failure by Administrative Agent to
approve or disapprove such draft Annual Operating Budget within 30 days after
receipt thereof shall be deemed to be an approval by Administrative Agent of
such draft. Borrower shall incorporate Administrative Agent's suggestions into a
final Annual Operating Budget, which, subject to the provisions of the last
sentence of this Section 5.11, shall be prepared no less than 30 days in advance
of each year.

               (b) Without limiting the foregoing, each Annual Operating Budget
delivered by Borrower pursuant to Section 3.5.23(b) shall also contain as an
attachment to such Annual Operating Budget a project budget setting forth all of
the anticipated Project Costs (including amounts payable under the relevant
Acquisition Documents) from and after the date of the initial Development Loan
in respect of the relevant Approved Project. Such project budget shall be deemed
to be part of the initial Annual Operating Budget for such Approved Project, but
shall not be updated as part of the yearly updating of the Annual Operating
Budget described and provided for in clause (a) above.

               (c) The O&M Costs in each Annual Operating Budget which are
subject to escalation limitations in the Project Documents shall not, absent
extraordinary circumstances, be increased by more than the amounts provided in
such Project Documents. Borrower shall continue to operate and maintain such
Approved Project, or cause such Approved Project to be operated and maintained,
within amounts not to exceed 110% of the aggregate amounts set forth in the
applicable Annual Operating Budget; provided, however, the costs for fuel shall
not be limited by the Annual Operating Budget. Pending approval of any Annual
Operating Budget in accordance with the terms of this Section 5.11, Borrower
shall continue to operate and maintain such Approved Project, or cause such
Approved Project to be operated and maintained, within the Annual Operating
Budget for such Approved Project then in effect; provided, further, that the
amounts specified therein shall be increased by the amounts specified in the
Project Documents.

     5.12 Further Assurances.

         5.12.1 Borrower shall, from time to time, execute, acknowledge, record,
register, deliver and/or file all such notices, statements, instruments and
other documents (including any memorandum of lease or other agreement, financing
statement, continuation statement, certificate of title or estoppel
certificate), relating to the Loans stating the interest and charges then due
and any known defaults, and take such other steps as may be necessary or
reasonably advisable to render fully valid and enforceable under all applicable
Legal Requirements the rights, liens and priorities of Secured Parties (or any
agent on their behalf) with respect to all Collateral and other security from
time to time furnished under this Agreement and the other Credit Documents or
intended to be so furnished, including (a) granting Liens, subject to no other
Liens other than Permitted Liens, in favor of Administrative Agent, for the
benefit of Secured Parties, in any Approved Project, Approved Turbine or portion
thereof not part of the Collateral and (b) causing its partners, members or
shareholders, as the case may be, to grant a first priority Lien to
Administrative Agent, for the benefit of Secured Parties, in all the ownership
interests in a Portfolio Entity, in each case to the extent permitted, without
any waivers, and consistently with the characterization of the Debt incurred and
Liens granted hereunder and under the other Credit Documents, in each case in
such form and at such times as shall be satisfactory to Administrative Agent,
and pay all fees and expenses (including reasonable attorneys' fees) incident to
compliance with this Section 5.12.1.

         5.12.2 If a Portfolio Entity shall at any time acquire any real
property or leasehold or other interest in real property related to an Approved
Project not covered by the Deeds of Trust or Mortgages, promptly upon such
acquisition (or on the Closing Date if such acquisition occurred prior thereto)
in furtherance of the Lien on the Approved Project and related Collateral
granted on the respective Funding Date, Borrower shall execute, deliver and
record a supplement to the applicable Deed of Trust or Mortgage, as the case may
be, or, if necessary, execute, deliver and record a new Deed of Trust or
Mortgage, as the case may be, in substantially the form attached hereto as
Exhibit D-3A or Exhibit D-3B, as the case may be, subjecting the real property
or leasehold or other interests so acquired to a lien and security interest in
favor of Administrative Agent, for the benefit of Secured Parties, subject only
to Permitted Liens and other exceptions to title approved by Administrative
Agent, securing all of the relevant Portfolio Entity's Obligations under the
Credit Documents; provided, that unless a Mortgage Event has occurred and is
continuing, with respect to any Approved Project located in the State of New
York, no Deeds of Trust or Mortgages shall be required in any circumstance where
Borrower reasonably determines and certifies (as verified by the Technical
Committee) that the documentation, filing, recording and other fees and expenses
reasonably anticipated to be incurred by any Portfolio Entity in connection with
the drafting, negotiating, filing and recording of any such Deed of Trust or
Mortgage are materially greater in the State of New York than the fees and
expenses customarily incurred by borrowers in similar transactions in respect of
real property located in other jurisdictions in the United States; provided,
however, that, at all times, Deeds of Trust or Mortgages, as the case may be,
shall be required to be maintained on the real property interests underlying at
least 50% of the Approved Projects then in existence (which percentage shall
based on the amount of Loan proceeds attributable and allocated to, or
contemplated to be attributable or allocated to, such Approved Projects). If
requested by Administrative Agent, Borrower shall obtain an appropriate
endorsement or supplement to the applicable Title Policy or procure a new Title
Policy insuring the Lien of Administrative Agent,

                                       91
<PAGE>   104

for the benefit of Secured Parties, in such additional property, subject only to
Permitted Liens and other exceptions to title approved by Administrative Agent,
and shall obtain subordination and nondisturbance agreements from applicable
third parties to the extent reasonably requested by Administrative Agent.

         5.12.3 Borrower shall perform, upon the request of Administrative
Agent, such reasonable acts as may be necessary to carry out the intent of this
Agreement and the other Credit Documents.

         5.12.4 Borrower shall, and shall cause each other Portfolio Entity to,
cause the Pledged Equity Interests to be "certificated securities" as defined in
Article 8 of the UCC and include in each appropriate Portfolio Entity's
constituent documents terms, in each case consistent with Section 8-103(c) of
the UCC, to the effect that the corresponding Pledged Equity Interests are
"securities" (as such term is defined in Article 8 of the UCC) governed by
Article 8 of the UCC.

     5.13 Maintenance of Insurance. Borrower shall maintain or cause to be
maintained on its behalf in effect at all times the types of insurance required
pursuant to Exhibit K hereto, in the amounts and on the terms and conditions
specified therein, with insurance companies rated "A-" or better, with a minimum
size rating of "IX," by Best's Insurance Guide and Key Ratings (or an equivalent
rating by another nationally recognized insurance rating agency of similar
standing if Best's Insurance Guide and Key Ratings shall no longer be published)
or other insurance companies of recognized responsibility satisfactory to
Administrative Agent.

     5.14 Market Study. On each 18 month anniversary of the later to occur of
(a) the date on which the initial Development Loan was made with respect to a
particular Approved Project and (b) the most recent date on which Borrower shall
have delivered a Power Marketing Consultant's report pursuant to Section
6.4.2(a)(v), Borrower shall deliver to Administrative Agent a Power Marketing
Consultant's certificate with respect to each such Approved Project, in
substantially the form of Exhibit G-8 hereto, with a Power Marketing
Consultant's report attached thereto (which report shall be in form and
substance reasonably satisfactory to the Technical Committee).

     5.15 Revenue Payment to Borrower. Borrower shall use its good faith
reasonable efforts to cause all Project Revenues, Insurance Proceeds, Eminent
Domain Proceeds, damage payments (including delay or performance liquidated
damage payments) and any other amounts due any Portfolio Entity to be paid or
otherwise delivered by such Persons making such payment or delivery directly to
Borrower for deposit in the Accounts as required pursuant to this Agreement, the
applicable Consent and the Depositary Agreement.

     5.16 Joint Venture Requirements.

         5.16.1 In the case of a Subject Project owned by a Project Owner which
is not a wholly-owned Subsidiary of Borrower, Borrower shall, and shall cause
each of the relevant Portfolio Entities to, comply in all respects with the
Co-Project Owner Requirements.

                                       92
<PAGE>   105

         5.16.2 In the case of a Subject Project that is only partially owned by
the relevant Project Owner, Borrower shall, and shall cause each of the relevant
Portfolio Entities to, comply in all respects with the Co-Joint Venturer
Requirements.

     5.17 Interest Rate Protection. In the event that the yield on five-year
U.S. Treasury Bonds exceeds 6.5% for ten consecutive Banking Days, within ten
Banking Days of such date, Borrower shall deliver to the Technical Committee a
plan (which plan shall be in form and substance reasonably satisfactory to the
Technical Committee) setting forth in reasonable detail Borrower's proposed
strategy for effectively limiting its exposure to such increased interest rates
and, to the extent required by such plan, Borrower shall maintain in full force
and effect, one or more Interest Rate Agreements with one or more banks or other
financial institutions in a manner consistent with such plan; provided that,
thereafter, Borrower may only terminate any such Interest Rate Agreement then in
effect if (a) such termination is in accordance with, and permitted by, such
plan and (b) the aggregate cost of liquidating and unwinding each such Interest
Rate Agreement is less than $5,000,000.

other Credit Documents, Borrower shall not become liable as a surety, guarantor,

Person; provided, however, that this Section 6.1 shall not be deemed to prohibit
the incurrence, creation, assumption or existence of Permitted Debt.

     6.2 Limitations on Liens. Borrower shall not, and shall not permit any of
the other Portfolio Entities which is Subsidiary thereof to, create, assume or
suffer to exist any Lien securing a charge or obligation on any properties or

         any such proposed release;

                  (vi) Borrower prepays the Loans (with amounts other than
         amounts in any Account or otherwise constituting Collateral) in an
         amount equal to the greater of (a) the positive difference (if any)

         which have been applied to the prepayment of such Loans prior to the
         date of any such proposed release, (b) with respect to any release that

         date of any such proposed release and (c) an amount equal to the
         positive difference (if any) between the aggregate amount of Loans
         outstanding minus the Capped Commitment Amount in effect after giving
         effect to any such sale, transfer or other disposition;

                  (vii) such release could not reasonably be expected to have a
         Borrower Material Adverse Effect (it being acknowledged and agreed that
         a Borrower Material Adverse Effect shall not be deemed to exist solely
         by reason of a change in (a) any minimum or average projected annual
         Interest Coverage Ratio or Deemed Debt Service Coverage Ratio for any
         Approved Project or all Approved Projects, (b) the geographic, fuel or
         commercial diversification of the Approved Projects or (c) the

                                       95

         Ratio, the Blended Ratio, Blended Development Loan Ratio, the Blended
         Working Capital Ratio, the Deemed Development Loan Ratio or the Capped

                  (viii) Borrower shall have delivered to the Technical
         Committee a certificate, in form and substance reasonably satisfactory
         to the Technical Committee, stating that each of the conditions set
         forth in this Section 6.4.2 have been satisfied and, after delivery of
         such certificate and other supporting documents as Borrower and the
         Technical Committee may agree to Banks, the Majority Banks have not
         objected in writing to the accuracy of such certification by the
         Determination Date.

               (b) In the event Borrower is required to prepay any Working
Capital Loans pursuant to Section 2.1.8(c)(iii), Banks shall promptly release
the applicable Funded Working Capital Assets and consent to the transfer of such
Funded Working Capital Assets to NRG Energy or a designee thereof, and
Administrative Agent shall promptly execute and deliver to Borrower and the
relevant Project Owner such documents and instruments as may be reasonably
necessary to release such Funded Working Capital Assets from the Liens of the
Collateral Documents and to permit such transfers of ownership.

               (c) Upon any release of the Approved Project or any Funded
Working Capital Asset (including the Approved Turbine) from the Lien of the
Collateral Documents related thereto as provided herein, the Approved Project or
such Funded Working Capital Asset shall cease to be an Approved Project or
Funded Working Capital Asset, as applicable, for purposes of this Agreement and
the other Credit Documents.

     6.5 Changes; Subsidiaries.

expected to have a Borrower Material Adverse Effect;

               (b) such new Subsidiary is being created for the primary purpose
of owning, directly or indirectly, an Approved Project, an Approved Turbine or
an Acquisition Plant;

               (c) Administrative Agent shall have received (i) copies of the
articles of incorporation, certificate of formation or certificate of
incorporation or charter or other state certified constituent documents of the
new Subsidiary, certified by the secretary of state of such new Subsidiary's
state of formation or incorporation, as the case may be, and (ii) copies of the
Bylaws or other comparable constituent documents of the new Subsidiary,
certified by its secretary or an assistant secretary (which Bylaws or other
constituent documents shall be in form and substance reasonably satisfactory to
Administrative Agent); and

                                       96
<PAGE>   109

               (d) if such new Subsidiary will not be a wholly-owned Subsidiary
of Borrower, the creation of such new Subsidiary complies with the Co-Project
Owner Requirements.

     6.6 Distributions.

         6.6.1 Subject to Sections 6.6.2, 6.6.3 and 6.6.4, Borrower shall not
directly or indirectly, make or declare any distribution (in cash, property or
obligation) on, repay any subordinated indebtedness or make any other payment on
account of, any interest in Borrower or any other Portfolio Entity (including
any transfers of any tax benefits) (a "Restricted Payment") unless:

               (i) no Event of Default, Inchoate Default, Project Default or

proceeds at Waterfall Level 6 and Waterfall Level 7 in accordance with Section
2.2.3(b) of the Depositary Agreement;

               (iv) no Borrower Material Adverse Effect has occurred and is
continuing, or could reasonably be expected to occur as a result of such
Restricted Payment;

and the other Portfolio Entities under Revenue Power Marketing Agreements, each
Historical Debt Service Coverage Ratio for the quarterly period ending on the

the negligence or misconduct of any such agents or attorneys-in-fact selected by
it with reasonable care.

         9.1.2 Administrative Agent and its respective directors, officers,
employees or agents shall not be responsible for any action taken or omitted to
be taken by it or them hereunder or under any other Credit Document or in
connection herewith or therewith, except for its or their own gross negligence
or willful misconduct. Without limiting the generality of the foregoing,
Administrative Agent (a) may treat the payee of any Note as the holder thereof
until Administrative Agent receives written notice of the assignment or transfer
thereof signed by such payee and in form satisfactory to Administrative Agent;
(b) may consult with legal counsel, 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 them in accordance with the advice of such

                                      106
<PAGE>   119

counsel, accountants or experts; (c) makes no warranty or representation to any
Bank for any statements, warranties or representations made in or in connection
with any Operative Document; (d) 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 Operative Document on the part of any party thereto or to
inspect the property (including the books and records) of any Portfolio Entity
or any other Person; and (e) shall not be responsible to any Bank for the due
execution, legality, validity, enforceability, genuineness, sufficiency or value
of any Operative Document or any other instrument or document furnished pursuant
hereto. Except as otherwise provided under this Agreement, Administrative Agent
shall take such action with respect to the Credit Documents as shall be directed
by the Required Banks.

     9.2 Reliance by Administrative Agent. Administrative Agent shall be
entitled to rely upon any certificate, notice or other document (including any
cable, telegram, telecopy or telex) believed by it to be genuine and correct and
to have been signed or sent by or on behalf of the proper Person or Persons, and
upon advice and statements of legal counsel, independent accountants and other
experts selected by Administrative Agent. As to any other matters not expressly
provided for by this Agreement, Administrative Agent shall not be required to
take any action or exercise any discretion, but shall be required to act or to
refrain from acting upon instructions of the Required Banks or, where expressly
provided, the Majority Banks (except that Administrative Agent shall not be
required to take any action which exposes Administrative Agent to personal
liability or which is contrary to this Agreement, any other Credit Document or
any Legal Requirement) and shall in all cases be fully protected in acting, or
in refraining from acting, hereunder or under any other Credit Document in
accordance with the instructions of the Required Banks (or, where so expressly
stated, the Majority Banks), and such instructions of the Required Banks (or
Majority Banks, where applicable) and any action taken or failure to act
pursuant thereto shall be binding on all of Banks.

     9.3 Non-Reliance. Each Bank represents that it has, independently and
without reliance on Administrative Agent or any other Bank, and based on such
documents and information as it has deemed appropriate, made its own appraisal
of the financial condition and affairs of the Portfolio Entities and decision to
enter into this Agreement and agrees that it will, independently and without
reliance upon Administrative Agent, or any other Bank, and based on such
documents and information as it shall deem appropriate at the time, continue to
make its own appraisals and decisions in taking or not taking action under this
Agreement. Each of Administrative Agent and any Bank shall not be required to
keep informed as to the performance or observance by NRG Energy, the Member, any
Affiliate Pledgor, any Portfolio Entity or its Affiliates under this Agreement
or any other document referred to or provided for herein or to make inquiry of,
or to inspect the properties or books of NRG Energy, the Member, any Affiliate
Pledgor, any Portfolio Entity or its Affiliates.

     9.4 Defaults. Administrative Agent shall not be deemed to have knowledge or
notice of the occurrence of any Inchoate Default, Event of Default, Project
Default or Project Inchoate Default unless Administrative Agent has received a
notice from a Bank or Borrower, referring to this Agreement, describing such
Inchoate Default, Event of Default, Project Default or Project Inchoate Default
and indicating that such notice is a notice of default. If Administrative Agent
receives such a notice of the occurrence of an Inchoate Default, Event of
Default, Project Default or Project Inchoate Default Administrative Agent shall
give notice thereof to Banks and

                                      107
<PAGE>   120

Borrower. Administrative Agent shall take such action with respect to any
Inchoate Default or Event of Default as is provided in Article 7 or if not
provided for in Article 7, as Administrative Agent shall be reasonably directed
by the Required Banks; provided, however, unless and until Administrative Agent
shall have received such directions, Administrative Agent may (but shall not be
obligated to) take such action, or refrain from taking such action, with respect
to such Inchoate Default or Event of Default as it shall deem advisable in the
best interest of Banks.

     9.5 Indemnification. Without limiting any Obligation of any of Portfolio
Entity hereunder, each Bank agrees to indemnify Administrative Agent and its
officers, directors, shareholders, controlling Persons, employees, agents and
servants, ratably in accordance with their Proportionate Shares for any and all
liabilities, obligations, losses, damages, penalties, actions, judgments, suits,
costs, expenses or disbursements of any kind or nature whatsoever which may at
any time be imposed on, incurred by or asserted against Administrative Agent or
any such Person in any way relating to or arising out of this Agreement or any
documents contemplated by or referred to herein or therein or the transactions
contemplated hereby or thereby or the enforcement of any of the terms hereof or
thereof or of any such other documents (to the extent Borrower has not paid any
such amounts pursuant to Section 5.10); provided, however, that no Bank shall be
liable for any of the foregoing to the extent they arise from Administrative
Agent's or any such Person's gross negligence or willful misconduct.
Administrative Agent of any such Person shall be fully justified in refusing to
take or to continue to take any action hereunder unless it shall first be
indemnified to its satisfaction by Banks against any and all liability and
expense which may be incurred by it by reason of taking or continuing to take
any such action. Without limitation of the foregoing, each Bank agrees to
reimburse Administrative Agent and any such Person promptly upon demand for its
ratable share of any out-of-pocket expenses (including counsel fees) incurred by
Administrative Agent or any such Person in connection with the preparation,
execution, administration or enforcement of, or legal advice in respect of
rights or responsibilities under, the Operative Documents, to the extent that
Administrative Agent or any such Person is not reimbursed for such expenses by
Borrower.

     9.6 Successor Administrative Agent. Administrative Agent acknowledges that
its current intention is to remain Administrative Agent hereunder. Nevertheless,
Administrative Agent may resign at any time by giving 15 days' written notice
thereof to Banks and Borrower. Administrative Agent may be removed involuntarily
only for a material breach of its duties and obligations hereunder or under the
other Credit Documents or for gross negligence or willful misconduct in
connection with the performance of its duties hereunder or under the other
Credit Documents and then only upon the affirmative vote of the Required Banks
(excluding Administrative Agent from such vote and Administrative Agent's
Proportionate Share of the Commitment from the amounts used to determine the
portion of the Commitment necessary to constitute the required Proportionate
Share of the remaining Banks). Upon any such resignation or removal, the
Required Banks shall have the right, with the consent of Borrower (such consent
not to be unreasonably withheld or delayed) to appoint a successor
Administrative Agent. If no successor Administrative Agent shall have been so
appointed by the Required Banks, and shall have accepted such appointment,
within 30 days after the retiring Administrative Agent's giving of notice of
resignation or Banks' removal of the retiring Administrative Agent, the retiring
Administrative Agent may, on behalf of Banks, with the consent of Borrower (such
consent not to be unreasonably withheld or delayed), appoint a successor
Administrative Agent, which shall be a Bank, if any Bank shall be willing to
serve, and otherwise shall be a commercial bank

                                      108
<PAGE>   121

having a combined capital and surplus of at least $500,000,000. Upon the
acceptance of any appointment as Administrative Agent under the Operative
Documents by a successor Administrative Agent, such successor Administrative
Agent shall thereupon succeed to and become vested with all the rights, powers,
privileges and duties of the retiring Administrative Agent, and the retiring
Administrative Agent shall be discharged from its duties and obligations as
Administrative Agent only under the Credit Documents. After any retiring
Administrative Agent's resignation or removal hereunder as Administrative Agent,
the provisions of this Article 9 shall inure to its benefit as to any actions
taken or omitted to be taken by it while it was Administrative Agent under the
Operative Documents.

     9.7 Authorization. Administrative Agent is hereby authorized by Banks to
execute, deliver and perform each of the Credit Documents to which
Administrative Agent is or is intended to be a party and each Bank agrees to be
bound by all of the agreements of Administrative Agent contained in the Credit
Documents. Administrative Agent is further authorized by Secured Parties to
release liens on property that the Portfolio Entities permitted to sell or
transfer pursuant to the terms of this Agreement, the other Credit Documents or
the Operative Documents, and to enter into agreements supplemental hereto for
the purpose of curing any formal defect, inconsistency, omission or ambiguity in
this Agreement or any Credit Document to which it is a party.

     9.8 Administrative Agent, Technical Committee and Other Agents. With
respect to its Commitment, the Loans made by it and any Note issued to it, each
of the financial institutions acting as Administrative Agent or as members of
the Technical Committee shall have the same rights and powers under the
Operative Documents as any other Bank and may exercise the same as though it
were not Administrative Agent or a member of the Technical Committee, as the
case may be. The term "Bank" or "Banks" shall, unless otherwise expressly
indicated, include members of the Technical Committee, in their individual
capacity. The financial institutions acting as Administrative Agent and members
of the Technical Committee 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 Borrower or any other Person, without any duty to account
therefor to Banks. The parties acknowledge and agree that, except as expressly
set forth herein, the Documentation Agent, the Arrangers and each other agent
and arranger listed on the signature pages hereto (other than Administrative
Agent) shall not, in such capacities (but not in their capacities as Banks),
have any rights, responsibilities, duties, obligations (including any fiduciary
obligations) or liability hereunder.

     9.9 Amendments; Waivers.

               (a) Subject to the provisions of this Section 9.9, unless
otherwise specified in this Agreement or another Credit Document, the Required
Banks (or Administrative Agent with the consent in writing of the Required
Banks) and Borrower may enter into agreements, waivers or supplements hereto for
the purpose of adding, modifying or waiving any provisions to the Credit
Documents or changing in any manner the rights of Banks or Borrower hereunder or
waiving any Inchoate Default or Event of Default; provided, however, that no
such supplement, waiver or agreement shall, without the consent of all of Banks:

         Portfolio Entity, except as expressly contemplated by Section 7.1.10,
         or

                  (v) Amend this Section 9.9; or

                  (vi) Release any Collateral from the Lien of any of the
         Collateral Documents, except as permitted in Section 6.4.2 and Section
         5.4.2 of the applicable Project Owner Guaranty, or allow release of any
         funds from any Account otherwise than in accordance with the terms
         hereof; or

                  (vii) Extend the maturity of any Loan or any of the Notes or
         reduce the principal amount thereof, or reduce the rate or change the
         time of payment of interest due on any Loan or any Notes; or

                  (viii) Extend the scheduled Loan Maturity Date; or

                  (ix) Reduce the amount or extend the payment date for any

         amounts; or

         payable to any Bank; or

                  (xi) Terminate any Project Owner Guarantee or the NRG Energy

         NRG Energy or any Project Owner thereunder, in each case except in
         accordance with its terms; or

                  (xii) Increase the maximum duration of Interest Periods
         permitted hereunder; or

                  (xiii) Subordinate the Loans to any other Indebtedness.

               (b) Without limiting anything contained in clause (a) above, (i)
no amendment, modification, termination or waiver of any provision of any Note
(other than by way of amending a document referred to therein) shall be
effective without the written concurrence of the Bank which is the holder of
that Note, and (ii) no amendment, modification, termination or waiver of any
provision of Article 9 or any other provision of this Agreement which, by its
terms, expressly requires the approval or concurrence or is expressly for the
benefit of

                                      110
<PAGE>   123

Administrative Agent shall be effective without the written concurrence of
Administrative Agent.

               (c) Any proposed action to be taken by the Required Banks under
the Credit Documents, including supplemental agreements with Borrower adding,
modifying or waiving any provisions to the Credit Documents or changing in any
manner the rights of Banks or Borrower hereunder or waiving any Inchoate Default
or Event of Default under this Section 9.9, shall be deemed so taken by the
Required Banks unless, after Banks have received from Administrative Agent
and/or Borrower notice of such proposed action together with all other
documentation and other information reasonably necessary for Banks'
consideration of such proposed action, Banks having Proportionate Shares
exceeding 40% at the time of such notice notify Administrative Agent of such
Banks' disapproval of such proposed action by the Determination Date.

     9.10 Withholding Tax.

          9.10.1 Administrative Agent may withhold from any interest payment to
any Bank an amount equivalent to any applicable withholding tax. If the forms or
other documentation required by Section 2.4 are not delivered to Administrative
Agent, then Administrative Agent may withhold from any interest payment to any
Bank not providing such forms or other documentation, an amount equivalent to
the applicable withholding tax.

          9.10.2 If the Internal Revenue Service or any authority of the United
States or other jurisdiction asserts a claim that Administrative Agent did not
properly withhold tax from amounts paid to or for the account of any Bank
(because the appropriate form was not delivered, was not properly executed, or
because such Bank failed to notify Administrative Agent of a change in
circumstances which rendered the exemption from, or reduction of, withholding
tax ineffective, or for any other reason) such Bank shall indemnify
Administrative Agent fully for all amounts paid, directly or indirectly, by
Administrative Agent as tax or otherwise, including penalties and interest,
together with all expenses incurred, including legal expenses, allocated staff
costs, and any out of pocket expenses.

          9.10.3 If any Bank sells, assigns, grants participation in, or
otherwise transfers its rights under this Agreement, the purchaser, assignee,
participant or transferee, as applicable, shall comply and be bound by the terms
of Sections 2.4.7, 9.10.1 and 9.10.2 as though it were such Bank.

     9.11 General Provisions as to Payments. Administrative Agent shall promptly
distribute to each Bank, subject to the terms of the assignment and assumption
agreement between Administrative Agent and such Bank, its pro rata share of each
payment of principal and interest payable to Banks on the Loans and of fees
hereunder received by Administrative Agent for the account of Banks and of any
other amounts owing under the Loans. The payments made for the account of each
Bank shall be made, and distributed to it, for the account of its domestic or
foreign lending office, as each Bank may designate in writing to Administrative
Agent. Banks shall have the right to alter designated lending offices upon five
Banking Days prior written notice to Administrative Agent and Borrower.

                                      111
<PAGE>   124

     9.12 Substitution of Bank. Should any Bank fail to make a Loan in violation
of its obligations under this Agreement (a "Non-Advancing Bank"), Administrative
Agent shall (a) in its sole discretion fund the Loan on behalf of the
Non-Advancing Bank or (b) cooperate with Borrower or any other Bank to find
another Person that shall be acceptable to Administrative Agent and that shall
be willing to assume the Non-Advancing Bank's obligations under this Agreement
(including the obligation to make the Loan which the Non-Advancing Bank failed
to make but without assuming any liability for damages for failing to have made
such Loan or any previously required Loan). Subject to the provisions of the
next following sentence, such Person shall be substituted for the Non-Advancing
Bank hereunder upon execution and delivery to Administrative Agent of an
agreement acceptable to Administrative Agent by such Person assuming the
Non-Advancing Bank's obligations under this Agreement, and all interest and fees
which would otherwise have been payable to the Non-Advancing Bank shall
thereafter be payable to such Person. Nothing in (and no action taken pursuant
to) this Section 9.12 shall relieve the Non-Advancing Bank from any liability it
might have to Borrower or to the other Banks as a result of its failure to make
any Loan or (b) limit any of the provisions set forth in Section 2.1.6.

     9.13 Participation.

          9.13.1 Nothing herein provided shall prevent any Bank from selling a
participation in one or more of its Commitments (and Loans made thereunder);
provided that (a) no such sale of a participation shall alter such Bank's or
Borrower's obligations hereunder, (b) any agreement pursuant to which any Bank
may grant a participation in its rights with respect to its Commitment shall
provide that, with respect to such Commitment, subject to the following proviso,
such Bank shall retain the sole right and responsibility to exercise the rights
of such Bank, and enforce the obligations of Borrower relating to such
Commitment, including the right to approve any amendment, modification or waiver
of any provision of this Agreement or any other Credit Document and the right to
take action to have the Obligations (or any portion thereof) of Portfolio
Entities declared due and payable pursuant to Article 7; provided, however, that
such agreement may provide that the participant may have rights to approve or
disapprove decreases in Commitments, interest rates or fees, lengthening of
maturity of any Loans, extend the payment date for any amount due under Article
2 hereof or release of any material Collateral. No recipient of a participation
in any Commitment or Loans of any Bank shall have any rights under this
Agreement or shall be entitled to any reimbursement for Taxes, Other Taxes
increased costs or reserve requirements under Section 2.4 or 2.6 or any other
indemnity or payment rights against Borrower (but shall be permitted to receive
from Bank granting such participation a proportionate amount which would have
been payable to Bank from whom such Person acquired its participation).

          9.13.2 Notwithstanding anything to the contrary contained herein, any
Bank (a "Granting Bank") may grant to a special purpose funding vehicle (a
"SPC"), identified as such in writing from time to time by the Granting Bank to
Administrative Agent and Borrower, the option to provide to Borrower all or any
part of any Loan that such Granting Bank would otherwise be obligated to make to
Borrower pursuant to this Agreement; provided that (i) nothing herein shall
constitute a commitment by any SPC to make any Loan, (ii) if an SPC elects not
to exercise such option or otherwise fails to provide all or any part of such
Loan, the Granting Bank shall be obligated to make such Loan pursuant to the
terms hereof. The making

                                      112
<PAGE>   125

of a Loan by an SPC hereunder shall utilize the Commitment of the Granting Bank
to the same extent, and as if, such Loan were made by such Granting Bank. Each
party hereto hereby agrees that no SPC shall be liable for any indemnity or
similar payment obligation under this Agreement (all liability for which shall
remain with the Granting Bank). In furtherance of the foregoing, each party
hereto hereby agrees (which agreement shall survive the termination of this
Agreement) that, prior to the date that is one year and one day after the
payment in full of all outstanding commercial paper or other senior indebtedness
of any SPC, it will not institute against, or join any other Person in
instituting against, such SPC any bankruptcy, reorganization, arrangement,
insolvency or liquidation proceedings under the laws of the United States or any
state thereof. In addition, notwithstanding anything to the contrary contained
in this Section 9.13, any SPC may (i) with notice to, but without the prior
written consent of, Borrower and Administrative Agent and without paying any
processing fee therefor, assign all or a portion of its interests in any Loans
to the Granting Bank or to any financial institutions (consented to by Borrower
and Administrative Agent) providing liquidity and/or credit support to or for
the account of such SPC to support the funding or maintenance of Loans and (ii)
disclose on a confidential basis any non-public information relating to its
Loans to any rating agency, commercial paper dealer or provider of any surety,
guarantee or credit or liquidity enhancement to such SPC. This section may not
be amended without the written consent of the SPC.

     9.14 Transfer of Commitment. Notwithstanding anything else herein to the
contrary, any Bank, after receiving (a) Borrower's prior written consent as to
the identity of the assignee (which consent shall not be unreasonably withheld
or delayed or, so long as an Event of Default has occurred and is continuing,
required) and (b) Administrative Agent's prior written consent (which consent
shall not be unreasonably withheld or delayed) may from time to time, at its
option, sell, assign, transfer, negotiate or otherwise dispose of a portion of
one or more of its Commitments (and Loans made thereunder) (including Bank's
interest in this Agreement and the other Credit Documents) to any bank or other
lending institution which in such assigning Bank's judgment is reasonably
capable of performing the obligations of a Bank hereunder and reasonably
experienced in project financing; provided, however, that no Bank (including any
assignee of any Bank) may assign any portion of its Commitment (including Loans)
of less than $1,000,000 (unless to another Bank); provided, further, that any
Bank may assign all or any portion of its Commitments to an Affiliate of such
Bank without the consent of any Person. In the event of any such assignment, (i)
the assigning Bank's Proportionate Share shall be reduced and its obligations
hereunder released by the amount of the Proportionate Share assigned to the new
lender, (ii) the parties to such assignment shall execute and deliver to
Administrative Agent an Assignment Agreement evidencing such sale, assignment,
transfer or other disposition substantially in the form of Exhibit L hereto or
otherwise satisfactory to Administrative Agent together with an assignment fee
payable to Administrative Agent of $3,500 (provided such assignment fee shall
not be required with respect to the initial syndication of Lead Arranger's and
Arrangers' Commitments) and any other related documentation reasonably requested
by Administrative Agent, including such withholding tax certificates as may be
appropriate pursuant to Section 2.4.7, (iii) at the assigning Bank's option, (A)
Borrower shall execute and deliver to such new lender new Notes in the forms
attached hereto as Exhibit B hereto in a principal amount equal to such new
lender's Commitment and (B) Borrower shall execute and exchange with the
assigning Bank a replacement note for any Note in an amount equal to the
Commitment retained by Bank, if any, (iv) to the extent the assigning Bank has
been issued any Notes in its favor, such Bank shall cancel and return each such
Note to Borrower promptly after the

                                      113
<PAGE>   126

effectiveness of any such assignment and (v) Exhibit H hereto shall be
automatically amended without further action to reflect such assignment and the
Proportionate Shares of Banks following such assignment. Thereafter, such new
lender shall be deemed to be a Bank and shall have all of the rights and duties
of a Bank (except as otherwise provided in this Article 9), in accordance with
its Proportionate Share, under each of the Credit Documents.

     9.15 Laws. Notwithstanding the foregoing provisions of this Article 9, no
sale, assignment, transfer, negotiation or other disposition of the interests of
any Bank hereunder or under the other Credit Documents shall be allowed if it
would require registration under the federal Securities Act of 1933, as then
amended, any other federal securities laws or regulations or the securities laws
or regulations of any applicable jurisdiction. Borrower shall, from time to time
at the request and expense of Administrative Agent, execute and deliver to
Administrative Agent, or to such party or parties as Administrative Agent may
designate, any and all further instruments as may in the opinion of
Administrative Agent be reasonably necessary or advisable to give full force and
effect to such disposition.

     9.16 Assignability to Federal Reserve Bank. Notwithstanding any other
provision contained in this Agreement or any other Credit Document to the
contrary, any Bank may assign all or any portion of the Loans or Notes held by
it to any Federal Reserve Bank or the United States Treasury as collateral
security pursuant to Regulation A of the Board of Governors of the Federal
Reserve System and any Operating Circular issued by such Federal Reserve Bank,
provided that any payment in respect of such assigned Loans or Notes made by
Borrower to or for the account of the assigning and/or pledging Bank in
accordance with the terms of this Agreement shall satisfy Borrower's obligations
hereunder in respect of such assigned Loans or Notes to the extent of such
payment. No such assignment shall release the assigning Bank from its
obligations hereunder and in no event shall such Federal Reserve Bank be
considered to be a "Bank" or be entitled to require the assigning Bank to take
or omit to take any action hereunder.

     9.17 Technical Committee. Each Bank hereby appoints and authorizes each of
Credit Suisse First Boston, ABN AMRO Bank N.V., Citicorp USA, Inc., Deutsche
Bank AG, Bayerische Hypo- und Vereinsbank AG, The Royal Bank of Scotland plc and
The Bank of Tokyo-Mitsubishi, Ltd. to act as its technical committee hereunder
and under the other Credit Documents (the "Technical Committee") with such
powers as are expressly delegated to the Technical Committee by the terms of
this Agreement and the other Credit Documents, together with such other powers
as are reasonably incidental thereto. The Technical Committee shall not have any
duties or responsibilities except those expressly set forth in this Agreement or
in any other Credit Document, or be a trustee or a fiduciary for any Bank.
Notwithstanding anything to the contrary contained herein the Technical
Committee shall not be required to take any action which is contrary to this
Agreement or any other Credit Documents or any Legal Requirement or exposes the
Technical Committee to any liability. All decisions and determinations to be
made by the Technical Committee hereunder and under the other Credit Documents
shall be made by the affirmative vote of six of its members (provided that if
any single member of the Technical Committee shall fail to approve or disapprove
any matter before it within 20 Banking Days from the date that at least five
other members of the Technical Committee shall have approved such matter, then
such matter shall be deemed to be approved by such member). Borrower and each
Bank hereby agrees that the protective provisions set forth in Section 5.10 and
Sections 9.1 through 9.5 shall apply to and protect, mutatis mutandis, each
member of the Technical

                                      114
<PAGE>   127

Committee and all determinations, decisions, actions or inactions taken or
omitted to be taken by the Technical Committee. In the event that any member of
the Technical Committee at any time reduces its Commitment to less than
$50,000,000, ceases to be a Bank hereunder, is removed from the Technical
Committee by the Majority Banks or otherwise resigns from the Technical
Committee, Borrower shall nominate (and submit such nominations in writing to
the remaining members of the Technical Committee) three Banks as a potential
replacement member within five Banking Days after the occurrence of any such
event (provided that each such nominee shall be a Bank with one of the six
largest Commitments at such time among Banks who are not then members of the
Technical Committee) and the remaining members of the Technical Committee shall
appoint one of such three nominated Banks as a replacement member to the
Technical Committee (thereafter, such replacement member shall have the same
rights and obligations as the other members of the Technical Committee).

     9.18 Notices to Technical Committee and Banks. Administrative Agent
promptly shall deliver all material documents, instruments and notices that it
receives hereunder and under the other Operative Documents to the Technical
Committee and to each Bank that is not a member of the Technical Committee.

for the benefit of Secured Parties and grants Administrative Agent a security
interest in and to all such deposits, sums, securities or other property.
Regardless of the adequacy of any other collateral, any Bank or any Affiliate
thereof (but only with the prior written consent of Administrative Agent), may
execute or realize on Banks' security interest in any such deposits or other

under this Agreement or any other Credit Document shall impair any such right,
power or remedy of Banks, nor shall it be construed to be a waiver of any such
breach or default, or an acquiescence therein, or of or in any similar breach or
default thereafter occurring, nor shall any waiver of any single Event of
Default, Inchoate Default, Project Default, Project Inchoate Default or other
breach or default be deemed a waiver of any other Event of Default, Inchoate

     11.12 Deed of Trust/Collateral Documents. The Loans are or will be secured
in part by the Deeds of Trust and Mortgages encumbering certain properties
associated with the Approved Projects in such Projects' respective states.
Reference is hereby made to the Deeds of Trust, Mortgages and the other
Collateral Documents for the provisions, among others, relating to the nature
and extent of the security provided thereunder, the rights, duties and
obligations of the Portfolio Entities and the rights of Administrative Agent and
Banks with respect to such security.

     11.13 Limitation on Liability. No claim shall be made by any Portfolio
Entity, the Member, any Affiliate Pledgor, NRG Energy or any of their
Affiliates, against Administrative Agent, Lead Arranger, Banks, any member of
the Technical Committee, any other Secured Party or any of their Affiliates,
directors, employees, attorneys or agents for any special, indirect,
consequential or punitive damages in respect of any breach or wrongful conduct
(whether or not the claim therefor is based on contract, tort or duty imposed by
law), in connection with, arising out of or in any way related to the
transactions contemplated by this Agreement or the other Operative Documents or
any act or omission or event occurring in connection therewith; and Borrower
hereby waives, releases and agrees not to sue upon any such claim for any such
damages, whether or not accrued and whether or not known or suspected to exist
in its favor.

     11.14 Waiver of Jury Trial. BANKS AND BORROWER HEREBY KNOWINGLY,
VOLUNTARILY, AND INTENTIONALLY WAIVE ANY RIGHTS THEY MAY HAVE TO A TRIAL BY JURY
IN RESPECT OF ANY LITIGATION BASED HEREON, OR ARISING OUT OF, UNDER, OR IN
CONNECTION WITH, THIS AGREEMENT OR ANY OTHER CREDIT DOCUMENT, OR ANY COURSE OF
CONDUCT, COURSE OF DEALING, STATEMENTS (WHETHER VERBAL OR WRITTEN), OR ACTIONS
OF BANKS OR BORROWER. THIS PROVISION IS A MATERIAL INDUCEMENT FOR BANKS TO ENTER
INTO THIS AGREEMENT.

     11.15 Consent to Jurisdiction. Banks and Borrower agree that any legal
action or proceeding by or against Borrower or with respect to or arising out of
this Agreement, the Notes, or any other Credit Document may be brought in or
removed to the courts of the State of New York, in and for the County of New
York, or of the United States of America for the Southern District of New York,
as Administrative Agent may elect. By execution and delivery of the Agreement,
Banks and Borrower accept, for themselves and in respect of their property,
generally and unconditionally, the jurisdiction of the aforesaid courts. Banks
and Borrower irrevocably consent to the service of process out of any of the
aforementioned courts in any

                                      123
<PAGE>   136

manner permitted by law. Nothing herein shall affect the right of Administrative
Agent to bring legal action or proceedings in any other competent jurisdiction,
including judicial or non-judicial foreclosure of any Deed of Trust or Mortgage.
Banks and Borrower further agree that the aforesaid courts of the State of New
York and of the United States of America shall have exclusive jurisdiction with
respect to any claim or counterclaim of Borrower based upon the assertion that
the rate of interest charged by Banks on or under this Agreement, the Loans
and/or the other Credit Documents is usurious. Banks and Borrower hereby waive
any right to stay or dismiss any action or proceeding under or in connection
with any or all of any Identified Project, Approved Project, Funded Working
Capital Asset, Acquisition, this Agreement or any other Credit Document brought
before the foregoing courts on the basis of forum non-conveniens.

     11.16 Usury. Nothing contained in this Agreement or the Notes shall be
deemed to require the payment of interest or other charges by Borrower or any
other Person in excess of the amount which the holders of the Notes may lawfully
charge under any applicable usury laws. In the event that Banks shall collect
moneys which are deemed to constitute interest which would increase the
effective interest rate to a rate in excess of that permitted to be charged by
applicable Legal Requirements, all such sums deemed to constitute interest in
excess of the legal rate shall, upon such determination, at the option of Banks,
be returned to Borrower or credited against the principal balance then
outstanding.

     11.17 Successors and Assigns. The provisions of this Agreement shall be
binding upon and inure to the benefit of the parties hereto and their respective
successors and assigns. Borrower may not assign or otherwise transfer any of its
rights under this Agreement except as provided in Section 6.16, and Banks may
not assign or otherwise transfer any of their rights under this Agreement except
as provided in Article 9.

     11.18 Counterparts. This Agreement and any amendments, waivers, consents or
supplements hereto or in connection herewith may be executed in any number of
counterparts and by different parties hereto in separate counterparts, each of
which when so executed and delivered shall be deemed an original, but all such
counterparts together shall constitute but one and the same instrument;
signature pages may be detached from multiple separate counterparts and attached
to a single counterpart so that all signature pages are physically attached to
the same document.

     11.19 Survival. All representations, warranties, covenants and agreements
made herein and in the certificates or other instruments delivered in connection
with or pursuant to this Agreement and the other Credit Documents shall be
considered to have been relied upon by the parties hereto and shall survive the
execution and delivery of this Agreement, the other Credit Documents and the
making of the Loans. Notwithstanding anything in this Agreement or implied by
law to the contrary, the agreements of Borrower set forth in Sections 2.4.4,
2.6.4, 2.7, 5.10, 9.1, 9.8, 10.1 and 11.4 and the agreements of Banks set forth
in Sections 9.1, 9.5 and 9.10.2 shall survive the payment and performance of the
Loans and other Obligations and the reimbursement of any amounts drawn
thereunder, and the termination of this Agreement.

<PAGE>   16

     Section 2.4's minimum amount requirement for each outstanding Borrowing, a
     portion thereof, as follows: (i) if such Borrowing is of Eurocurrency
     Loans, on the last day of the Interest Period applicable thereto, the
     Borrower may continue part or all of such Borrowing as Eurocurrency Loans
     for an Interest Period or Interest Periods specified by the Borrower or

     Borrowing is of Base Rate Loans, on any Business Day, the Borrower may
     convert all or part of such Borrowing into Eurocurrency Loans for an
     Interest Period or Interest Periods specified by the Borrower. The Borrower
     shall give all such notices requesting the advance, continuation, or

     notice shall be irrevocable once given and, if by telephone, shall be
     promptly confirmed in writing). Notices of the continuation of a Borrowing
     of Eurocurrency Loans for an additional Interest Period or of the
     conversion of part or all of a Borrowing of Eurocurrency Loans into Base
     Rate Loans or of Base Rate Loans into Eurocurrency Loans must be given by
     no later than 11:00 a.m. (New York time) at least three (3) Business Days

     notices concerning the advance, continuation, or conversion of a Borrowing
     shall specify the date of the requested advance, continuation or conversion
     of a Borrowing (which shall be a Business Day), the amount of the requested

     thereto. The Borrower agrees that the Agent may rely on any such telephonic
     or telecopy notice given by any person it in good faith believes is an
     Authorized Representative without the necessity of independent
     investigation, and in the event any such notice by telephone conflicts with
     any written confirmation, such telephonic notice shall govern if the Agent
     has acted in reliance thereon. There may be no more than five different
     Interest Periods in effect at any one time.

          (b) Notice to the Banks. The Agent shall give prompt telephonic or
     telecopy notice to each Bank of any notice from the Borrower received
     pursuant to Section 2.5(a) above. The Agent shall give notice to the
     Borrower and each Bank by like means of the interest rate applicable to
     each Borrowing of Eurocurrency Loans and the amount thereof.

          (c) Borrower's Failure to Notify. Any outstanding Borrowing of Base
     Rate Loans shall, subject to Section 6.2 hereof, automatically be continued
     for an additional Interest Period on the last day of its then current
     Interest Period unless the Borrower has notified the Agent within the
     period required by Section 2.5(a) that it intends to convert such Borrowing
     into a Borrowing of Eurocurrency Loans or notifies the Agent within the
     period required by Section 2.8(a) that it intends to prepay such Borrowing.
     If the Borrower fails to give notice pursuant to Section 2.5(a) above of
     the continuation or conversion of any outstanding principal amount of a
     Borrowing of Eurocurrency Loans before the last day of its then current
     Interest Period within the period required by Section 2.5(a) and has not
     notified the Agent within the period required by Section 2.8(a) that it
     intends to

                                       12

<PAGE>   17

     prepay such Borrowing, such Borrowing shall automatically be converted into
     a Borrowing of Base Rate Loans, subject to Section 6.2 hereof.

          (d) Disbursement of Loans. Not later than 12:00 p.m. (New York time)
     on the date of any requested advance of a new Borrowing of Eurocurrency
     Loans, and not later than 1:00 p.m. (New York time) on the date of any
     requested advance of a new Borrowing of Base Rate Loans, subject to Section

     Loans at the Agent's principal office in New York, New York or such other
     office as the Agent has previously agreed to, in writing, with the
     Borrower.

          (e) Agent Reliance on Bank Funding. Unless the Agent shall have been
     notified by a Bank before the date on which such Bank is scheduled to make
     payment to the Agent of the proceeds of a Loan (which notice shall be
     effective upon receipt) that such Bank does not intend to make such
     payment, the Agent may assume that such Bank has made such payment when due
     and the Agent may in reliance upon such assumption (but shall not be
     required to) make available to the Borrower the proceeds of the Loan to be
     made by such Bank and, if any Bank has not in fact made such payment to the
     Agent, such Bank shall, on demand, pay to the Agent the amount made
     available to the Borrower attributable to such Bank together with interest
     thereon in respect of each day during the period commencing on the date
     such amount was made available to the Borrower and ending on (but
     excluding) the date such Bank pays such amount to the Agent at a rate per
     annum equal to the Federal Funds Rate. If such amount is not received from
     such Bank by the Agent immediately upon demand, the Borrower will, on
     demand, repay to the Agent the proceeds of the Loan attributable to such
     Bank with interest thereon at a rate per annum equal to the interest rate
     applicable to the relevant Loan.

     Section 2.6 Interest Periods. As provided in Section 2.5(a) hereof, at the

to such Loans from among the available options. The term "Interest Period" means
the period commencing on the date a Borrowing of Loans is advanced, continued,
or created by conversion and ending: (a) in the case of Base Rate Loans, on the

calendar quarter if such Loan is advanced, continued or created by conversion on
the last Business Day of a calendar quarter), and (b) in the case of
Eurocurrency Loans, 1, 2, 3, or 6 months thereafter; provided, however, that:

          (a) any Interest Period for a Borrowing of Base Rate Loans that
     otherwise would end after the Maturity Date shall end on the Maturity Date;

                                       13

<PAGE>   18

          (b) for any Borrowing of Eurocurrency Loans, the Borrower may not
     select an Interest Period that extends beyond the Maturity Date;

          (c) whenever the last day of any Interest Period would otherwise be a
     day that is not a Business Day, the last day of such Interest Period shall
     be extended to the next succeeding Business Day, provided that, if such
     extension would cause the last day of an Interest Period for a Borrowing of
     Eurocurrency Loans to occur in the following calendar month, the last day
     of such Interest Period shall be the immediately preceding Business Day;
     and

          (d) for purposes of determining an Interest Period for a Borrowing of
     Eurocurrency Loans, a month means a period starting on one day in a
     calendar month and ending on the numerically corresponding day in the next
     calendar month; provided, however, that if there is no numerically
     corresponding day in the month in which such an Interest Period is to end
     or if such an Interest Period begins on the last Business Day of a calendar
     month, then such Interest Period shall end on the last Business Day of the
     calendar month in which such Interest Period is to end.

     Section 2.7 Maturity of Loans. Unless an earlier maturity is provided for
hereunder (whether by acceleration or otherwise), each Loan shall mature and
become due and payable by the Borrower on the Maturity Date.

     Section 2.8 Prepayments.

          (a) The Borrower may prepay without premium or penalty and in whole or
     in part (but, if in part, then: (i) if such Borrowing is of Base Rate
     Loans, in an amount not less than $1,000,000, (ii) if such Borrowing is of
     Eurocurrency Loans in an amount not less than $1,000,000, and (iii) in an
     amount such that the minimum amount required for a Borrowing pursuant to
     Section 2.4 hereof remains outstanding) any Borrowing of Eurocurrency Loans
     upon three Business Days prior notice to the Agent or, in the case of a
     Borrowing of Base Rate Loans, notice delivered to the Agent no later than
     11:00 a.m. (New York time) on the date of prepayment, such prepayment to be
     made by the payment of the principal amount to be prepaid and accrued
     interest thereon to the date fixed for prepayment. In the case of
     Eurocurrency Loans, such prepayment may only be made on the last day of the
     Interest Period then applicable to such Loans. The Agent will promptly
     advise each Bank of any such prepayment notice it receives from the
     Borrower.

          (b) If the aggregate principal amount of outstanding Loans shall at
     any time for any reason exceed the Total Credit Facility Commitments then
     in effect, the Borrower shall, immediately and without notice or demand,
     pay the amount of such excess to the Agent for the ratable benefit of the
     Banks as a prepayment of the Loans. Immediately upon determining the need
     to make any such prepayment the Borrower shall notify the Agent of such
     required prepayment.

                                       14

<PAGE>   19

          (c) The Borrower shall apply all the net proceeds of any public or
     private sale of equity securities, issuance of securities that are
     convertible into stock, any equity-linked offering or any other equity
     offering made by the Borrower (collectively, an "Equity Offering") to
     prepayment of the Loans.

          (d) Each such prepayment shall be accompanied by a payment of all
     accrued and unpaid interest on the Loans prepaid and shall be subject to
     Section 2.12.

     Section 2.9 Repricing Events.

          (a) In the event that the Rating of the Borrower is downgraded by
     either of Moody's Investors Service, Inc. or Standard & Poor's Ratings
     Services or any successors thereto from the Rating in effect on the
     Effective Date, the Base Rate Margin, Eurocurrency Margin and Facility Fee
     Rate shall be increased from the Base Rate Margin, Eurocurrency Margin and
     Facility Fee Rate then in effect by, respectively, .50%, .50% and .25%,
     with effect from the date of issuance of such Rating downgrade and for so
     long as such lower Rating is in effect.

          (b) For so long as any Obligations remain outstanding hereunder on and
     after January 1, 2002, the Base Rate Margin, Eurocurrency Margin and
     Facility Fee Rate shall be increased from the Base Rate Margin,
     Eurocurrency Margin and Facility Fee Rate then in effect by, respectively,
     .25%, .30%, and .05%, with effect from January 1, 2002.

     Section 2.10 Default Rate. If any payment of any Obligation is not made
when due (whether by acceleration or otherwise), such Obligation shall bear
interest, computed on the basis of a year of 360 days and actual days elapsed
(except for Base Rate Loans bearing interest based on the rate described in
clause (i) of the definition of Base Rate, in which case such Loan shall bear
interest computed on the basis of a year of 365 or 366 days, as applicable, and
the actual number of days elapsed) from the date such payment was due until paid
in full, payable on demand, at a rate per annum equal to:

          (a) for any Obligation other than a Eurocurrency Loan, the sum of two
     percent (2%) plus the Base Rate Margin plus the Base Rate from time to time
     in effect; and

          (b) for any Eurocurrency Loan, the sum of two percent (2%) plus the
     rate of interest in effect thereon at the time of such default until the
     end of the Interest Period applicable thereto and, thereafter, at a rate
     per annum equal to the sum of two percent (2%) plus the Base Rate Margin
     plus the Base Rate from time to time in effect.

     Section 2.11 The Notes.

          (a) The Loans made to the Borrower by a Bank shall be evidenced by a
     single promissory note of the Borrower issued to such Bank in the form of

                                       15

<PAGE>   20

     Exhibit A hereto. Each such promissory note is hereinafter referred to as a
     "Note" and collectively such promissory notes are referred to as the
     "Notes."

          (b) Each Bank shall record on its books and records or on a schedule
     to its Note the amount of each Loan advanced, continued, or converted by
     it, all payments of principal and interest and the principal balance from
     time to time outstanding thereon, the type of such Loan, and, for any
     Eurocurrency Loan, the Interest Period and the interest rate applicable
     thereto. The record thereof, whether shown on such books and records of a
     Bank or on a schedule to any Note, shall be prima facie evidence as to all
     such matters; provided, however, that the failure of any Bank to record any
     of the foregoing or any error in any such record shall not limit or
     otherwise affect the obligation of the Borrower to repay all Loans made to
     it hereunder together with accrued interest thereon. At the request of any
     Bank and upon such Bank tendering to the Borrower the Note to be replaced,
     the Borrower shall furnish a new Note to such Bank to replace any
     outstanding Note, and at such time the first notation appearing on a
     schedule on the reverse side of, or attached to, such Note shall set forth
     the aggregate unpaid principal amount of all Loans, if any, then
     outstanding thereon.

     Section 2.12 Funding Indemnity. If any Bank shall incur any loss, cost or
expense (including, without limitation, any loss of profit, and any loss, cost
or expense incurred by reason of the liquidation or re-employment of deposits or
other funds acquired by such Bank to fund or maintain any Eurocurrency Loan or
the relending or reinvesting of such deposits or amounts paid or prepaid to such
Bank) as a result of:

          (a) any payment (whether by acceleration or otherwise), prepayment or
     conversion of a Eurocurrency Loan on a date other than the last day of its
     Interest Period,

          (b) any failure (because of a failure to meet the conditions of
     Section 6 or otherwise) by the Borrower to borrow or continue a
     Eurocurrency Loan, or to convert a Base Rate Loan into a Eurocurrency Loan,
     on the date specified in a notice given pursuant to Section 2.5(a) or
     established pursuant to Section 2.5(c) hereof,

          (c) any failure by the Borrower to make any payment of principal on
     any Eurocurrency Loan (x) when due (whether by acceleration or otherwise),
     or (y) on the date specified in a notice of prepayment, or

          (d) any acceleration of the maturity of a Eurocurrency Loan as a
     result of the occurrence of any Event of Default hereunder,

then, upon the demand of such Bank, the Borrower shall pay to such Bank such
amount as will reimburse such Bank for such loss, cost or expense. If any Bank
makes such a claim for compensation, it shall provide to the Borrower, with a
copy to the Agent, a certificate executed by an officer of such Bank setting
forth the amount of such loss, cost or expense in reasonable detail (including
an explanation of the basis for and the

                                       16

<PAGE>   21

computation of such loss, cost or expense) and the amounts shown on such
certificate if reasonably calculated shall be conclusive absent manifest error.

     Section 2.13 Commitment Terminations. The Borrower shall have the right at
any time and from time to time, upon five (5) Business Days prior written notice
to the Agent, to terminate the Credit Facility Commitments without premium or
penalty, in whole or in part, any partial termination to be (i) in an amount not
less than $5,000,000, and (ii) allocated ratably among the Banks in proportion
to their respective Percentages, provided that the Credit Facility Commitments
may not be reduced to an amount less than the amount of all Loans then
outstanding. The Agent shall give prompt notice to each Bank of any such
termination of Commitments. Any termination of Credit Facility Commitments
pursuant to this Section 2.13 may not be reinstated. In addition, that portion
of the Credit Facility Commitments that remains unused after the fifth
Disbursement (after giving effect to all Loans to be made on such fifth
Disbursement) shall be terminated and may not be reinstated. In addition, the
Banks shall have the right to terminate the Credit Facility Commitments if no
Disbursement has occurred on or before the Termination Date.

SECTION 3. FEES.

     Section 3.1 Fees.

          (a) Agent Fee. The Borrower shall pay, or cause to be paid, to the
     Agent on the Effective Date the Agent Fee.

          (b) Facility Fee. For the period from the Effective Date to and
     including the Maturity Date, the Borrower shall pay to the Agent for the
     ratable account of the Banks in accordance with their Percentages a
     facility fee accruing at a rate per annum equal to the Facility Fee Rate on
     the average daily amount of the Commitments (whether used or unused), or if
     the Commitments have expired or terminated, on the principal amount of
     Loans. Such facility fee is payable in arrears on the last Business Day of
     each calendar quarter and on the Maturity Date, unless the Commitments are
     terminated in whole on an earlier date, in which event the fee for the
     period to but not including the date of such termination shall be paid in
     whole on the date of such termination.

          (c) Outstanding Fee. If any Obligations remain outstanding on December
     31, 2001, the Borrower shall pay, or cause to be paid, to the Agent on that
     date, for the ratable account of the Banks in accordance with their
     Percentages, a fee equal to .10% of the amount of Obligations outstanding
     on that date.

          (d) Fee Calculations. All fees payable under this Agreement shall be
     payable in U.S. Dollars and shall be computed on the basis of a year of 360
     days, for the actual number of days elapsed. All determinations of the
     amount of fees

                                       17

<PAGE>   22

     shall be conclusive absent manifest error.

SECTION 4. PLACE AND APPLICATION OF PAYMENTS.

     Section 4.1 Place and Application of Payments. All payments of principal of
and interest on the Loans, and of all other amounts payable by the Borrower

of the Agent in New York, New York (or such other location in the United States
as the Agent may designate to the Borrower). Any payments received after such
time shall be deemed to have been received by the Agent on the next Business
Day. All such payments shall be made free and clear of, and without deduction
for, any set-off, counterclaim, levy, withholding or any other deduction of any
kind in U.S. Dollars, in immediately available funds at the place of payment.
The Agent will promptly thereafter cause to be distributed like funds relating
to the payment of principal or interest on Loans or applicable fees ratably to
the Banks and like funds relating to the payment of any other amount payable to
any Person to such Person, in each case to be applied in accordance with the
terms of this Agreement.

SECTION 5. REPRESENTATIONS AND WARRANTIES.

     The Borrower hereby represents and warrants to each Bank as to itself and,
where the following representations and warranties apply to Subsidiaries, as to
each of its Subsidiaries, as follows:

     Section 5.1 Corporate Organization and Authority. The Borrower and each of
its Subsidiaries is duly organized, validly existing and in good standing under
the laws of its jurisdiction of organization, except where such failure to be in
good standing would not, individually or in the aggregate, have a Material
Adverse Effect. Each is duly qualified to transact business in each jurisdiction
in which such qualification is required, whether by reason of ownership or
leasing of property or the conduct of business or otherwise, except where
failure to be so qualified would not, individually or in the aggregate, have a
Material Adverse Effect. Each has the power and authority required to own, lease
and operate its properties and to conduct its business as currently conducted,
except where failure to have such power and authority could not, individually or
in the aggregate, have a Material Adverse Effect.

     Section 5.2 Subsidiaries. Schedule 5.2 (as updated quarterly pursuant to
Section 7.6(b) hereof or otherwise from time to time in writing by the Borrower)
hereto identifies each Subsidiary and the jurisdiction of its incorporation. All
of the issued and outstanding shares of capital stock of each Subsidiary are
validly issued and outstanding and fully paid and nonassessable except as set
forth on Schedule 5.2 hereto. All such shares owned by the Borrower are owned
beneficially, and of record, and, except in the case of any Project Finance
Subsidiary, free of any Lien.

                                       18

<PAGE>   23

     Section 5.3 Corporate Authority and Validity of Obligations. The Borrower
has full right and authority to enter into this Agreement and the other Credit
Documents to which it is a party, to make the borrowings herein provided for, to
issue its Notes in evidence thereof, and to perform all of its obligations under
the Credit Documents to which it is a party. Each Credit Document to which it is
a party has been duly authorized, executed and delivered by the Borrower and
constitutes valid and binding obligations of the Borrower enforceable in
accordance with its terms. No Credit Document, nor the performance or observance
by the Borrower of any of the matters or things therein provided for,
contravenes any provision of law or any charter or by-law provision of the
Borrower or any material Contractual Obligation of or affecting the Borrower or
any of its Properties or results in or requires the creation or imposition of
any Lien on any of the Properties or revenues of the Borrower.

     Section 5.4 Financial Statements. All financial statements heretofore
delivered to the Banks showing historical performance of the Borrower for each
of the Borrower's fiscal years ending on or before December 31, 1999, and for
the Borrower's quarter ended September 30, 2000 have been prepared in accordance
with generally accepted accounting principles applied on a basis consistent,
except as otherwise noted therein, with that of the previous fiscal year. Each
of such financial statements fairly presents on a consolidated basis the
financial condition of the Borrower as of the dates thereof and the results of
operations for the periods covered thereby. The Borrower and its Subsidiaries
have no material contingent liabilities other than those disclosed in such
financial statements referred to in this Section 5.4 or in comments or footnotes
thereto, or in any report supplementary thereto, heretofore furnished to the
Banks. Since December 31, 1999, there has been no material adverse change in the
business, operations, Property or financial or other condition, or business
prospects, of the Borrower or any of its Subsidiaries.

     Section 5.5 No Litigation; No Labor Controversies.

          (a) Except as set forth on Schedule 5.5 (as updated quarterly pursuant
     to Section 7.6(b) hereof or otherwise from time to time in writing by the
     Borrower), there is no litigation or governmental proceeding pending, or to
     the knowledge of the Borrower, threatened, against the Borrower or any
     Subsidiary which, if adversely determined, could (individually or in the
     aggregate) have a Material Adverse Effect.

          (b) Except as set forth on Schedule 5.5 (as updated quarterly pursuant
     to Section 7.6(b) hereof or otherwise from time to time in writing by the
     Borrower), there are no labor controversies pending or, to the best
     knowledge of the Borrower, threatened against the Borrower or any
     Subsidiary which could have a Material Adverse Effect.

     Section 5.6 Taxes. The Borrower and its Subsidiaries have filed all United
States federal tax returns, and all other tax returns, required to be filed and
have paid all taxes due pursuant to such returns or pursuant to any assessment
received by the Borrower or any Subsidiary, except such taxes, if any, as are
being contested in good

                                       19

<PAGE>   24

faith and for which adequate reserves have been provided. No notices of tax
liens have been filed and no claims are being asserted concerning any such
taxes, which liens or claims are material to the financial condition of the
Borrower or any of its Subsidiaries (individually or in the aggregate). The
charges, accruals and reserves on the books of the Borrower and its Subsidiaries
for any taxes or other governmental charges are adequate.

     Section 5.7 Approvals. No authorization, consent, license, exemption,
filing or registration with any court or governmental department, agency or
instrumentality (including under the Public Utility Holding Company Act of 1935,
as amended ("PUHCA")), nor any approval or consent of the stockholders of the
Borrower or any Subsidiary or from any other Person, is necessary to the valid
execution, delivery or performance by the Borrower or any Subsidiary of any
Credit Document to which it is a party.

     Section 5.8 Validity of Notes. When executed, authenticated and delivered
pursuant to the provisions of this Agreement against payment of the
consideration therefore, the Notes will be duly issued and will constitute
legal, valid and binding obligations of the Borrower, enforceable in accordance
with their terms, except for the effect of bankruptcy, insolvency,
reorganization, moratorium and other similar laws relating to or affecting the
rights of creditors generally, and will rank pari passu with all other
outstanding unsecured indebtedness of the Borrower.

     Section 5.9 ERISA. With respect to each Plan, the Borrower and each other
member of the Controlled Group has fulfilled its obligations under the minimum
funding standards of and is in compliance in all material respects with the
Employee Retirement Income Security Act of 1974, as amended ("ERISA"), and with
the Code to the extent applicable to it and has not incurred any liability to
the Pension Benefit Guaranty Corporation ("PBGC") or a Plan under Title IV of
ERISA other than a liability to the PBGC for premiums under Section 4007 of
ERISA. The Borrower does not have any contingent liabilities for any
post-retirement benefits under a Welfare Plan, other than liability for
continuation coverage described in Part 6 of Title I of ERISA.

     Section 5.10 Government Regulation. Neither the Borrower nor any Subsidiary
is an "investment company" within the meaning of the Investment Company Act of
1940, as amended.

     Section 5.11 Margin Stock; Use of Proceeds. Neither the Borrower nor any
Subsidiary is engaged principally, or as one of its primary activities, in the
business of extending credit for the purpose of purchasing or carrying margin
stock ("margin stock" to have the same meaning herein as in Regulation U of the
Board of Governors of the Federal Reserve System). The proceeds of the Loans are
to be used solely for the purposes set forth in and permitted by Section 7.10.
The Borrower will not use the proceeds of any Loan in a manner that violates any
provision of Regulation U or X of the Board of Governors of the Federal Reserve
System.

     Section 5.12 Licenses and Authorizations; Compliance Laws. The Borrower and
each of its Subsidiaries has all necessary licenses, permits and governmental

                                       20

<PAGE>   25

authorizations to own and operate its Properties and to carry on its business as
currently conducted and contemplated. The Borrower and each of its Subsidiaries
is in compliance with all applicable laws, regulations, ordinances and orders of
any governmental or judicial authorities except for any such law, regulation,
ordinance or order which, the failure to comply therewith, could not reasonably
be expected to have a Material Adverse Effect.

     Section 5.13 Ownership of Property Liens. The Borrower and each Subsidiary
has good title to or valid leasehold interests in all its Property. None of the
Borrower's Property is subject to any Lien, except as permitted in Section 7.9.

     Section 5.14 No Burdensome Restrictions; Compliance with Agreements.
Neither the Borrower nor any Subsidiary is (a) party or subject to any law,
regulation, rule or order, or any Contractual Obligation that (individually or
in the aggregate) could have a Material Adverse Effect or (b) in default in the
performance, observance or fulfillment of any of the obligations, covenants or
conditions contained in, nor has any event occurred (and is continuing) that
constitutes or would (whether or not with the giving of notice and/or with the
passage of time and/or the fulfillment of any other requirement) constitute, to
the knowledge of the Borrower, a default or any breach or failure to perform by
the Borrower under any indenture, mortgage, loan agreement, lease or other
agreement or instrument to which it is a party, which default could have a
Material Adverse Effect.

     Section 5.15 Full Disclosure. All information heretofore furnished by the
Borrower to the Agent or any Bank for purposes of or in connection with the
Credit Documents or any transaction contemplated thereby is, and all such
information hereafter furnished by the Borrower to the Agent or any Bank will
be, true and accurate in all material respects and not misleading on the date as

Borrower or a Subsidiary from discontinuing the operation or maintenance of any
such Properties if such discontinuance is not disadvantageous to the Banks or
the holders of the Notes, and is, in the judgment of the Borrower, desirable in
the conduct of its business or the business of its Subsidiary.

          (c) The Borrower will (i) promptly (and in any event within three
     Business Days after an officer of the Borrower has knowledge thereof) give
     notice to the Agent and each Bank (x) of the occurrence of any Default or
     Event of Default or (y) of any payment default or payment event of default
     aggregating $20,000,000 or more under any Contractual Obligation of the

of the properties of the Borrower or any of its Subsidiaries, to examine all of
their books of account, records, reports and other papers, to make copies and
extracts therefrom, and to discuss their respective affairs, finances and

     Section 7.9 Liens. The Borrower shall cause the Obligations to at all times
rank at least pari passu with all other senior unsecured obligations of the
Borrower. The Borrower will not create, incur, permit to exist or to be incurred
any Lien of any kind on any Property owned by the Borrower; provided, however,
that this Section 7.9 shall not apply to nor operate to prevent:

          (a) Liens upon any Property acquired by the Borrower to secure any
     Indebtedness (which for purposes of this Section 7.9(a) shall include
     non-recourse obligations) of the Borrower incurred to finance or refinance
     the purchase price of such Property (including Property which was initially
     purchased with equity), provided that any such Lien shall apply only to the
     Property that was so acquired and the aggregate principal amount of
     Indebtedness secured by such Liens shall not exceed the cost or value of
     the acquired Property;

          (b) Other Liens not to exceed 10% of Consolidated Net Tangible Assets;

          (c) Liens on the stock or other equity interests of Project Finance

     the foregoing paragraphs (a) through (c), inclusive.

     Section 7.10 Use of Proceeds; Regulation U. The proceeds of the Borrowing

connection with the acquisition of certain generating assets from Conectiv and
the financing thereof, including but not limited to any payments made under

engineering, environmental, financial and other advisors and outside consultants
and for other general corporate purposes. The Borrower will not use any part of
the proceeds of any of the Borrowings directly or indirectly to purchase or
carry any margin stock (as defined in Section 5.11 hereof) or to extend credit
to others for the purpose of purchasing or carrying any such margin stock.

     Section 7.11 Mergers, Consolidations and Sales of Assets.

          (a) The Borrower will not consolidate with or merge into any other
     Person or sell, convey, transfer or lease its properties and assets
     substantially as an entirety to any Person, and the Borrower shall not
     permit any Person to consolidate with or merge into the Borrower, unless:
     (i) immediately prior to and immediately following such consolidation,
     merger, sale or lease, and after giving effect thereto, no Default or Event
     of Default shall have occurred and be continuing; and (ii) the Borrower is
     the surviving or continuing corporation, or the surviving or continuing
     corporation that acquires by sale, conveyance, transfer or

                                       27

<PAGE>   32

     lease (a) has a Rating equal to or better than the Rating of the Borrower
     in effect prior to such consolidation or merger and (y) is incorporated in
     the United States and expressly assumes the payment and performance of all
     Obligations of the Borrower under the Credit Documents pursuant to
     documentation in form and substance satisfactory to the Required Banks.

          (b) Except for the sale of the properties and assets of the Borrower
     substantially as an entirety pursuant to subsection (a) above, and other
     than assets required to be sold to conform with governmental regulations,
     the Borrower shall not sell or otherwise dispose of any assets (other than
     short-term, readily marketable investments purchased for cash management
     purposes with funds not representing the proceeds of other asset sales) if
     on a pro forma basis, the aggregate net book value of all such sales during
     the most recent 12-month period would exceed ten percent (10%) of
     Consolidated Net Tangible Assets computed as of the end of the most recent
     fiscal quarter preceding such sale; provided, however, that any such sales
     shall be disregarded for purposes of this ten percent (10%) limitation if
     the proceeds are invested in assets in similar or related lines of business
     of the Borrower and, provided further, that the Borrower may sell or
     otherwise dispose of assets in excess of such ten percent (10%) if the
     proceeds from such sales or dispositions, which are not reinvested as
     provided above, are retained by the Borrower as cash or cash equivalents at
     all times until invested in assets in similar or related lines of business
     of the Borrower.

     Section 7.12 Consolidated Net Worth. The Borrower will at all times cause
its Consolidated Net Worth to be equal to or greater than the Minimum
Consolidated Net Worth.

     Section 7.13 Indebtedness to Consolidated Capitalization. The Borrower will
at the end of each of its fiscal quarters maintain a ratio of its Indebtedness
to Consolidated Capitalization of not more than 0.68 to 1.00, provided that for
not more than two consecutive months in any six month period (any such two month
period being referred to herein as a "Non-Conforming Period"), the ratio of the
Borrower's Indebtedness to Consolidated Capitalization may increase to not more
than 0.72 to 1.00 so long as the Borrower delivers to the Agent within 30 days
after the end of any such Non-Conforming Period written affirmation from Moody's
Investors Service, Inc. and Standard and Poor's Ratings Service, Inc. that the
respective Ratings which were in effect prior to such Non-Conforming Period
remains in effect and that the Borrower has not been placed in any "credit-watch
with negative implications" or similar type of category. For purposes of this
covenant, only fifty percent (50%) of any Indebtedness of the Borrower
constituting performance guarantees of obligations of the Borrower's Affiliates
shall be deemed Indebtedness, provided that if any demand has been made on such
guarantee, the full amount of such guarantee shall be included in calculating
Indebtedness.

     Section 7.14 Compliance with Laws. Without limiting any of the other
covenants of the Borrower in this Section 7, the Borrower will conduct its
business, and otherwise be, in compliance with all applicable laws, regulations,
ordinances, writs, judgments, injunctions, decrees, awards and orders of any
governmental or judicial

                                       28

<PAGE>   33

authorities; provided, however, that the Borrower shall not be required to
comply with any such law, rule, regulation, ordinance, writ, judgments,
injunction, decree, award or order if the failure to comply therewith could not
reasonably be expected to have a Material Adverse Effect.

     Section 7.15 Takeout Financing. In the event that all of the Obligations
have not been repaid by the date that is sixty (60) days prior to the Maturity
Date, the Borrower shall either (a) notify the Banks that it has sufficient
funds to repay the Obligations on or before the Maturity Date and identify the
source of those funds, or (b) commence to take all necessary or desirable steps
to issue debt securities of the Borrower, in an aggregate amount sufficient that
the net proceeds of such sale shall not be less than the amount of the
Obligations which remain outstanding as of the time of such sale. The Borrower
agrees that such debt securities will be offered and sold at pricing and other
terms and conditions recommended by the Banks as necessary and appropriate to
effect a sale of such debt securities in an amount sufficient to repay the
outstanding Obligations. In connection with such offering and sale, each of the
Banks shall be designated a managing underwriter of such offering, and such
underwriting shall be done on a best efforts basis and pursuant to documentation
acceptable to the Borrower and to each Bank. The net proceeds of such offering
shall be used to repay the Obligations to the Banks and, if such proceeds exceed
the amount of the outstanding Obligations, any excess shall belong to the
Borrower.

     Section 8.1 Events of Default. Any one or more of the following shall

those described in subsections (e) or (f) of Section 8.1 hereof has occurred and

directed by the Required Banks, terminate the remaining Commitments and all
other obligations of the Banks hereunder on the date stated in such notice
(which may be the date thereof); and (b) if so directed by the Required Banks,
declare the principal of and the accrued interest on all outstanding Notes to be
forthwith due and payable and thereupon all outstanding Notes, including both
principal and interest thereon, shall be and become immediately due and payable
together with all other amounts payable under the Credit Documents without
further demand, presentment, protest or notice of any kind. The Agent, after
giving notice to the Borrower pursuant to Section 8.1(c), 8.1(d) or this Section
8.2, shall also promptly send a copy of such notice to the other Banks, but the
failure to do so shall not impair or annul the effect of such notice.

     Section 8.3 Bankruptcy Defaults. When any Event of Default described in
subsections (e) or (f) of Section 8.1 hereof has occurred and is continuing,
then all outstanding Notes shall immediately become due and payable together
with all other amounts payable under the Credit Documents without presentment,
demand, protest or notice of any kind and the obligation of the Banks to extend
further credit pursuant to any of the terms hereof shall immediately terminate.

     Section 8.4 Notice of Default. The Agent shall give notice to the Borrower
under Section 8.1(c) or 8.1(d) hereof promptly upon being requested to do so by
any Bank and shall thereupon notify all the Banks thereof.

Bank, and any other holder of any Note outstanding hereunder, all reasonable
costs and expenses incurred or paid by the Agent or such Bank or any such
holder, including attorneys' fees and court costs, in connection with any
Default or Event of Default by the Borrower hereunder or in connection with the
enforcement of any of the Credit Documents.

SECTION 9. CHANGE IN CIRCUMSTANCES.

     Section 9.1 Change of Law. Notwithstanding any other provisions of this
Agreement or any Note if at any time after the date hereof any change in
applicable law or regulation or in the interpretation thereof makes it unlawful
for any Bank to make or continue to maintain Eurocurrency Loans or to perform
its obligations as contemplated hereby, such Bank shall promptly give notice
thereof to the Borrower and such Bank's obligations to make or maintain
Eurocurrency Loans under this Agreement shall terminate until it is no longer
unlawful for such Bank to make or maintain Eurocurrency Loans. The Borrower
shall prepay on demand the outstanding principal amount of any such affected
Eurocurrency Loans, together with all interest accrued thereon at a rate per
annum equal to the interest rate applicable to such Loan; provided, however,
subject to all of the terms and conditions of this Agreement, the Borrower may
then elect to borrow the principal amount of the affected Eurocurrency Loans
from such Bank by means of Base Rate Loans from such Bank, which Base

                                       31

<PAGE>   36

Rate Loans shall not be made ratably by the Banks but only from such affected
Bank.

     Section 9.2 Unavailability of Deposits or Inability to Ascertain, or
Inadequacy of, LIBOR. If on or prior to the first day of any Interest Period for
any Borrowing of Loans:

          (a) the Agent determines that deposits in U.S. Dollars (in the
     applicable amounts) are not being offered to it in the federal funds or
     eurocurrency interbank market, as applicable, for such Interest Period, or
     that by reason of circumstances affecting the federal funds or interbank
     eurocurrency market, as applicable, adequate and reasonable means do not
     exist for ascertaining the applicable Federal Funds Rate or LIBOR; or

          (b) Banks having 25% or more of the aggregate amount of the Total
     Credit Facility Commitments reasonably determine and so advise the Agent
     that the Federal Funds Rate or LIBOR, as applicable, as reasonably
     determined by the Agent will not adequately and fairly reflect the cost to
     such Banks or Bank of funding their or its Loans or Loan for such Interest
     Period;

then the Agent shall forthwith give notice thereof to the Borrower and the
Banks, whereupon until the Agent notifies the Borrower that the circumstances
giving rise to such suspension no longer exist, the obligations of the Banks or
of the relevant Bank to make Base Rate Loans bearing interest at the Federal
Funds Rate or Eurocurrency Loans in the currency so affected, as applicable,
shall be suspended.

     Section 9.3 Increased Cost and Reduced Return.

          (a) If, on or after the date hereof, the adoption of any applicable
     law, rule or regulation, 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 any Bank (or its Lending Office)
     with any request or directive (whether or not having the force of law but,
     if not having the force of law, compliance with which is customary in the
     relevant jurisdiction) of any such authority, central bank or comparable
     agency:

               (i) shall subject any Bank (or its Lending Office) to any tax,
          duty or other charge with respect to its Eurocurrency Loans, its
          Notes, or its obligation to make Eurocurrency Loans, or shall change
          the basis of taxation of payments to any Bank (or its Lending Office)
          of the principal of or interest on its Eurocurrency Loans, or any
          other amounts due under this Agreement in respect of its Eurocurrency
          Loans or its obligation to make Eurocurrency Loans (except for changes
          in the rate of tax on the overall net income or profits of such Bank
          or its Lending Office imposed by the jurisdiction in which such Bank
          or its lending office is

                                       32

<PAGE>   37

          incorporated in which such Bank's principal executive office or
          Lending Office is located); or

               (ii) shall impose, modify or deem applicable any reserve, special
          deposit or similar requirement (including, without limitation, any
          such requirement imposed by the Board of Governors of the Federal
          Reserve System, but excluding with respect to any Eurocurrency Loans
          any such requirement included in an applicable Eurocurrency Reserve
          Percentage) against assets of, deposits with or for the account of, or
          credit extended by, any Bank (or its Lending Office) or shall impose
          on any Bank (or its Lending Office) or on the interbank market any
          other condition affecting its Eurocurrency Loans, its Notes, or its
          obligation to make Eurocurrency Loans;

and the result of any of the foregoing is to increase the cost to such Bank (or
its Lending Office) of making or maintaining any Eurocurrency Loan, or to reduce
the amount of any sum received or receivable by such Bank (or its Lending
Office) under this Agreement or under its Notes with respect thereto, by an
amount deemed by such Bank to be material, then, within fifteen (15) days after
demand by such Bank (with a copy to the Agent), the Borrower shall be obligated
to pay to such Bank such additional amount or amounts as will compensate such
Bank for such increased cost or reduction. In the event any law, rule,
regulation or interpretation described above is revoked, declared invalid or
inapplicable or is otherwise rescinded, and as a result thereof a Bank is
determined to be entitled to a refund from the applicable authority for any
amount or amounts which were paid or reimbursed by Borrower to such Bank
hereunder, such Bank shall, so long as no Event of Default has occurred and is
then continuing, refund such amount or amounts to Borrower without interest.

          (b) If, after the date hereof, any Bank or the Agent shall have
     determined that the adoption of any applicable law, rule or regulation
     regarding capital adequacy, or any change therein (including, without
     limitation, any revision in the Final Risk-Based Capital Guidelines of the
     Board of Governors of the Federal Reserve System (12 CFR Part 208, Appendix
     A; 12 CFR Part 225, Appendix A) or of the Office of the Comptroller of the
     Currency (12 CFR Part 3, Appendix A), or in any other applicable capital
     rules heretofore adopted and issued by any governmental authority), 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 any Bank (or its
     Lending Office) with any request or directive regarding capital adequacy
     (whether or not having the force of law but, if not having the force of
     law, compliance with which is customary in the applicable jurisdiction) of
     any such authority, central bank or comparable agency, has or would have
     the effect of reducing the rate of return on such Bank's capital, or on the
     capital of any corporation controlling such Bank, as a consequence of its
     obligations hereunder to a level below that which such Bank could have
     achieved but for such adoption, change or compliance (taking into
     consideration such Bank's policies

                                       33

<PAGE>   38

     with respect to capital adequacy) by an amount deemed by such Bank to be
     material, then from time to time, within fifteen (15) days after demand by
     such Bank (with a copy to the Agent), the Borrower shall pay to such Bank
     such additional amount or amounts as will compensate such Bank for such
     reduction.

          (c) Each Bank that determines to seek compensation under this Section
     9.3 shall notify the Borrower and the Agent of the circumstances that
     entitle the Bank to such compensation pursuant to this Section 9.3 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 such Bank, be otherwise disadvantageous to such Bank. A
     certificate of any Bank claiming compensation under this Section 9.3 and
     setting forth the additional amount or amounts to be paid to it hereunder
     shall be conclusive in the absence of manifest error. In determining such
     amount, such Bank may use any reasonable averaging and attribution methods.

          (d) If any Bank (other than Credit Suisse First Boston, Merrill Lynch
     Capital Corporation or Citicorp USA, Inc.) has demanded compensation or
     given notice of its intention to demand compensation under this Section 9.3
     or the Borrower is required to pay any additional amount to any Bank under
     Section 9.3, the Borrower shall have the right, with the assistance of the
     Agent, to seek a substitute Bank or Banks reasonably satisfactory to the
     Agent (which may be one or more of the Banks) to replace such Bank under
     this Agreement and on the date of replacement, the Borrower shall pay all
     accrued interest and fees to the Bank being replaced. The Bank to be so
     replaced shall cooperate with the Borrower and substitute Bank to
     accomplish such substitution, provided that all of such Bank's Credit
     Facility Commitment is replaced.

     Section 9.4 Lending Offices. Each Bank may, at its option, elect to make
its Loans hereunder at the branch, office or affiliate specified on the
appropriate signature page hereof or in the assignment agreement which any
assignee bank executes pursuant to Section 11.12 hereof (each a "Lending
Office") for each type of Loan available hereunder or at such other of its
branches, offices or affiliates as it may from time to time elect and designate
in a written notice to the Borrower and the Agent.

     Section 9.5 Discretion of Bank as to Manner of Funding. Notwithstanding any
other provision of this Agreement, each Bank shall be entitled to fund and
maintain its funding of all or any part of its Loans in any manner it sees fit,
it being understood, however, that for the purposes of this Agreement all
determinations hereunder shall be made as if each Bank had actually funded and
maintained each Eurocurrency Loan through the purchase of deposits of U.S.
Dollars in the eurocurrency interbank market having a maturity corresponding to
such Loan's Interest Period and bearing an interest rate equal to LIBOR for such
Interest Period.

SECTION 10. THE AGENT.

     Section 10.1 Appointment and Authorization of Agent. Each Bank hereby
appoints Credit Suisse First Boston as the Agent under the Credit Documents and
hereby authorizes the agent to take such action as Agent on its behalf and to
exercise such powers under the Credit Documents as are delegated to the Agent by
the terms thereof, together with such powers as are reasonably incidental
thereto. The Agent shall have no duties or responsibilities except those
expressly set forth in this Agreement and the Credit Documents. The duties of
the Agent shall be mechanical and administrative in nature; the Agent shall not
have by reason of this Agreement or any other Credit Document a fiduciary
relationship in respect of any Bank, the holder of any Note or any other Person;
and nothing in this Agreement or any other Credit Document, expressed or
implied, is intended to or shall be so construed as to impose upon the Agent any
obligations in respect of this Agreement or any other Credit Document except as
expressly set forth herein or therein.

     Section 10.2 Agent and its Affiliates. The Agent shall have the same rights
and powers under this Agreement and the other Credit Documents as any other Bank
and may exercise or refrain from exercising the same as though it were not the
Agent, and the Agent and its affiliates may accept deposits from, lend money to,
and generally engage in any kind of business with the Borrower or any Affiliate
of the Borrower as if it were not the Agent under the Credit Documents. The term
"Bank" as used herein and in all other Credit Documents, unless the context
otherwise clearly requires, includes the Agent in its individual capacity as a
Bank. References in Section 2 hereof to the Agent's Loans, or to the amount
owing to the Agent for which an interest rate is being determined, refer to the
Agent in its individual capacity as a Bank.

     Section 10.3 Action by Agent. If the Agent receives from the Borrower a
written notice of an Event of Default pursuant to Section 7.6(c)(i) hereof, the
Agent shall promptly give each of the Banks written notice thereof. The
obligations of the Agent under the Credit Documents are only those expressly set
forth therein. Without limiting the generality of the foregoing, the Agent shall
not be required to take any action hereunder with respect to any Default or
Event of Default, except as expressly provided in Sections 8.2 and 8.5. In no
event, however, shall the Agent be required to take any action in violation of
applicable law or of any provision of any Credit Document, and the Agent shall
in all cases be fully justified in failing or refusing to act hereunder or under
any other Credit Document unless it shall be first indemnified to its reasonable
satisfaction by the Banks against any and all costs, expense, and liability
which may be incurred by it by reason of taking or continuing to take any such
action. The Agent shall be entitled to assume that no Default or Event of
Default exists unless notified to the contrary by a Bank or the Borrower. In all
cases in which this Agreement and the other Credit Documents do not require the
Agent to take certain actions, the Agent shall be fully justified in using its
discretion in failing to take or in taking any action hereunder and thereunder.

     Section 10.4 Consultation with Experts. The Agent may consult with legal
counsel, independent public accountants and other experts selected by it and
shall not be

                                       35

<PAGE>   40

liable for any action taken or omitted to be taken by it in good faith in
accordance with the advice of such counsel, accountants or experts.

     Section 10.5 Liability of Agent; Credit Decision. Neither the Agent nor any
of its directors, officers, agents, or employees shall be liable for any action
taken or not taken by it in connection with the Credit Documents (i) with the
consent or at the request of the Required Banks or (ii) in the absence of its
own gross negligence or willful misconduct. Neither the Agent nor any of its
directors, officers, agents or employees shall be responsible for or have any
duty to ascertain, inquire into or verify: (i) any statement, warranty or
representation made in connection with this Agreement, any other Credit Document
or any Credit Event; (ii) the performance or observance of any of the covenants
or agreements of the Borrower or any other party contained herein or in any
other Credit Document; (iii) the satisfaction of any condition specified in
Section 6 hereof, except receipt of items required to be delivered to the Agent;
or (iv) the validity, effectiveness, genuineness, enforceability, perfection,
value, worth or collectability hereof or of any other Credit Document or of any
other documents or writing furnished in connection with any Credit Document; and
the Agent makes no representation of any kind or character with respect to any
such matter mentioned in this sentence. The Agent may execute any of its duties
under any of the Credit Documents by or through employees, agents, and
attorneys-in-fact and shall not be answerable to the Banks, the Borrower, or any
other Person for the default or misconduct of any such agents or
attorneys-in-fact selected with reasonable care. The Agent shall not incur any
liability by acting in reliance upon any notice, consent, certificate, other
document or statement (whether written or oral) believed by it to be genuine or
to be sent by the proper party or parties. In particular and without limiting
any of the foregoing, the Agent shall have no responsibility for confirming the
accuracy of any Compliance Certificate or other document or instrument received
by it under the Credit Documents. The Agent may treat the payee of any Note as
the holder thereof until written notice of transfer shall have been filed with
the Agent signed by such payee in form satisfactory to the Agent. Each Bank
acknowledges that it has independently and without reliance on the Agent or any
other Bank, and based upon such information, investigations and inquiries as it
deems appropriate, made its own credit analysis and decision to extend credit to
the Borrower in the manner set forth in the Credit Documents. It shall be the
responsibility of each Bank to keep itself informed as to the creditworthiness
of the Borrower and any other relevant Person, and the Agent shall have no
liability to any Bank with respect thereto.

     Section 10.6 Indemnity. The Banks shall ratably, in accordance with their
respective Percentages, indemnify and hold the Agent, and its directors,
officers, employees, agents and representatives harmless from and against any
liabilities, losses, costs or expenses suffered or incurred by it under any
Credit Document or in connection with the transactions contemplated thereby,
regardless of when asserted or arising, except to the extent they are promptly
reimbursed for the same by the Borrower and except to the extent that any event
giving rise to a claim was caused by the gross negligence or willful misconduct
of the party seeking to be indemnified. The obligations of the Banks under this
Section 10.6 shall survive termination of this Agreement.

                                       36

<PAGE>   41

     Section 10.7 Resignation of Agent and Successor Agent. The Agent may resign
at any time by giving written notice thereof to the Banks and the Borrower. Upon
any such resignation of the Agent, the Required Banks shall have the right to
appoint a successor Agent with the consent of the Borrower, provided, that at
any time an Event of Default has occurred and is continuing, no such consent
shall be required. If no successor Agent shall have been so appointed by the
Required Banks, and shall have accepted such appointment, within thirty (30)
days after the retiring Agent's giving of notice of resignation, then the
retiring Agent may, on behalf of the Banks, with the consent of the Borrower,
appoint a successor Agent, which shall be any Bank hereunder or any 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 $200,000,000. Upon
the acceptance of its appointment as the Agent hereunder, such successor Agent
shall thereupon succeed to and become vested with all the rights and duties of
the retiring or removed Agent under the Credit Documents, and the retiring Agent
shall be discharged from its duties and obligations thereunder. After any
retiring Agent's resignation hereunder as Agent, the provisions of this Section
10 and all protective provisions of the other Credit Documents shall inure to
its benefit as to any actions taken or omitted to be taken by it while it was
Agent.

SECTION 11. MISCELLANEOUS.

     Section 11.1 Withholding Taxes.

          (a) Payments Free of Withholding. Subject to Section 11.1(b) hereof,
     each payment by the Borrower under this Agreement or the other Credit
     Documents shall be made without withholding for or on account of any
     present or future taxes (other than overall net income taxes on the
     recipient). If any such withholding is so required, the Borrower shall make
     the withholding, pay the amount withheld to the appropriate governmental
     authority before penalties attach thereto or interest accrues thereon and
     forthwith pay such additional amount as may be necessary to ensure that the
     net amount actually received by each Bank and the Agent free and clear of
     such taxes (including such taxes on such additional amount) is equal to the
     amount which that Bank or the Agent (as the case may be) would have
     received had such withholding not been made. If the Agent or any Bank pays
     any amount in respect of any such taxes, penalties or interest the Borrower
     shall reimburse the Agent or that Bank for that payment on demand in the
     currency in which such payment was made. If the Borrower pays any such
     taxes, penalties or interest, it shall deliver official tax receipts
     evidencing that payment or certified copies thereof to the Bank or Agent on
     whose account such withholding was made (with a copy to the Agent if not
     the recipient of the original) on or before the thirtieth day after
     payment. If any Bank or the Agent determines it has received or been
     granted a credit against or relief or remission for, or repayment of, any
     taxes paid or payable by it because of any taxes, penalties or interest
     paid by the Borrower and evidenced by such a tax receipt, such Bank or
     Agent shall, to the extent it can do so without prejudice to the retention
     of the amount of such credit, relief, remission or repayment, pay to the
     Borrower such amount as such Bank or Agent determines is attributable to
     such

                                       37

<PAGE>   42

     deduction or withholding and which will leave such Bank or Agent (after
     such payment) in no better or worse position than it would have been in if
     the Borrower had not been required to make such deduction or withholding.
     Nothing in this Agreement shall interfere with the right of each Bank and
     the Agent to arrange its tax affairs in whatever manner it thinks fit nor
     oblige any Bank or the Agent to disclose any information relating to its
     tax affairs or any computations in connection with such taxes.

          (b) U.S. Withholding Tax Exemptions. Each Bank that is not a United
     States person (as such term is defined in Section 7701(a)(30) of the Code)
     shall submit to the Borrower and the Agent on or before the earlier of the
     date of the initial Disbursement and thirty (30) days after the date
     hereof, two duly completed and signed copies of either Form W8BEN (relating
     to such Bank and entitling it to a complete exemption from withholding
     under the Code on all amounts to be received by such Bank, including fees,
     pursuant to the Credit Documents and the Loans) or Form W8ECI (relating to
     all amounts to be received by such Bank, including fees, pursuant to the
     Credit Documents and the Loans) of the United States Internal Revenue
     Service. Thereafter and from time to time, each Bank shall submit to the
     Borrower and the Agent such additional duly completed and signed copies of
     one or the other of such Forms (or such successor forms as shall be adopted
     from time to time by the relevant United States taxing authorities) as may
     be (i) requested by the Borrower in a written notice, directly or through
     the Agent, to such Bank and (ii) required under then-current United States
     law or regulations to avoid or reduce United States withholding taxes on
     payments in respect of all amounts to be received by such Bank, including
     fees, pursuant to the Credit Documents or the Loans.

          (c) Inability of Bank to Submit Forms. If any Bank determines, as a
     result of any change in applicable law, regulation or treaty, or in any
     official application or interpretation thereof, that it is unable to submit
     to the Borrower or Agent any form or certificate that such Bank is
     obligated to submit pursuant to subsection (b) of this Section 11.1 or that
     such Bank is required to withdraw or cancel any such form or certificate
     previously submitted or any such form or certificate otherwise becomes
     ineffective or inaccurate, such Bank shall promptly notify the Borrower and
     Agent of such fact and the Bank shall to that extent not be obligated to
     provide any such form or certificate and will be entitled to withdraw or
     cancel any affected form or certificate, as applicable.

     Section 11.2 No Waiver of Rights. No delay or failure on the part of the
Agent or any Bank or on the part of the holder or holders of any Note in the
exercise of any power or right under any Credit Document shall operate as a
waiver thereof, nor as an acquiescence in any default, nor shall any single or
partial exercise thereof preclude any other or further exercise of any other
power or right, and the rights and remedies hereunder of the Agent, the Banks
and the holder or holders of any Notes are cumulative to, and not exclusive of,
any rights or remedies which any of them would otherwise have.

                                       38

<PAGE>   43

     Section 11.3 Non-Business Day. If any payment of principal or interest on
any Loan or of any other Obligation shall fall due on a day which is not a
Business Day, interest or fees (as applicable) at the rate, if any, such Loan or
other Obligation bears for the period prior to maturity shall continue to accrue
on such Obligation from the stated due date thereof to and including the next
succeeding Business Day, on which the same shall be payable.

     Section 11.4 Documentary Taxes. The Borrower agrees that it will pay any
documentary, stamp or similar taxes payable in respect to any Credit Document,
including interest and penalties, in the event any such taxes are assessed,
irrespective of when such assessment is made and whether or not any credit is
then in use or available hereunder.

     Section 11.5 Survival of Representations. All representations and
warranties made herein or in certificates given pursuant hereto shall survive
the execution and delivery of this Agreement and the other Credit Documents, and
shall continue in full force and effect with respect to the date as of which
they were made as long as any credit is in use or available hereunder.

     Section 11.6 Survival of Indemnities. All indemnities and all other
provisions relative to reimbursement to the Banks of amounts sufficient to
protect the yield of the Banks with respect to the Loans, including, but not
limited to, Section 2.12, Section 9.3 and Section 11.15 hereof, shall survive
the termination of this Agreement and the other Credit Documents and the payment
of the Loans and all other Obligations.

     Section 11.7 Set-Off.

          (a) In addition to any rights now or hereafter granted under
     applicable law and not by way of limitation of any such rights, upon the
     occurrence of any Event of Default, each Bank, each Affiliate of a Bank,
     and each subsequent holder of any Note is hereby authorized by the Borrower
     at any time or from time to time, without notice to the Borrower or to any
     other Person, any such notice being hereby expressly waived, to set off and
     to appropriate and to apply any and all deposits (general or special,
     including, but not limited to, Indebtedness evidenced by certificates of
     deposit, whether matured or unmatured, and in whatever currency
     denominated) and any other Indebtedness at any time held or owing by that
     Bank, its Affiliate or that subsequent holder to or for the credit or the
     account of the Borrower, whether or not matured, against and on account of
     the obligations and liabilities of the Borrower to that Bank, its Affiliate
     or that subsequent holder under the Credit Documents, including, but not
     limited to, all claims of any nature or description arising out of or
     connected with the Credit Documents, irrespective of whether or not (a)
     that Bank, its Affiliate or that subsequent holder shall have made any
     demand hereunder or (b) the principal of or the interest on the Loans or
     Notes and other amounts due hereunder shall have become due and payable
     pursuant to Section 8 and although said obligations and liabilities, or any
     of them, may be contingent or unmatured.

                                       39

<PAGE>   44

          (b) Each Bank agrees with each other Bank a party hereto that if such
     Bank shall receive and retain any payment, whether by set-off or
     application of deposit balances or otherwise, on any of the Loans in excess
     of its ratable share of payments on all such obligations then outstanding
     to the Banks, then such Bank shall purchase for cash at face value, but
     without recourse, ratably from each of the other Banks such amount of the
     Loans, or participations therein, held by each such other Bank (or interest
     therein) as shall be necessary to cause such Bank to share such excess
     payment ratably with all the other Banks; provided, however, that if any
     such purchase is made by any Bank, and if such excess payment or part
     thereof is thereafter recovered from such purchasing Bank, the related
     purchases from the other Banks shall be rescinded ratably and the purchase
     price restored as to the portion of such excess payment so recovered, but
     without interest unless the purchasing Bank is required to pay interest
     thereon, in which case each Bank returning funds to such purchasing Bank
     shall pay its pro rata share of such interest.

     Section 11.10 Successors and Assigns. This Agreement shall be binding upon
the Borrower and its successors and assigns, and shall inure to the benefit of
each of the Banks and the benefit of their respective successors and assigns,
including any subsequent holder of any Note. The Borrower may not assign any of
its rights or obligations under any Credit Document without the written consent
of all of the Banks.

     Section 11.11 Participants and Note Assignees. Each Bank shall have the
right at its own cost to grant participations (to be evidenced by one or more
agreements or certificates of participation) in the Loans made and Credit
Facility Commitment held by such Bank at any time and from time to time, and to
assign its rights under such Loans or the Note evidencing such Loans to a
federal reserve bank; provided that (i) no such participation or assignment
shall relieve any Bank of any of its obligations under this Agreement, (ii) no
such assignee or participant shall have any rights under this Agreement except
as provided in this Section 11.11, and (iii) the Agent shall have no obligation
or responsibility to such participant or assignee, except that nothing herein is
intended to affect the rights of an assignee of a Note to enforce the Note
assigned. Any party to which such a participation or assignment has been granted
shall have the benefits of Section 2.12 and Section 9.3, but shall not be
entitled to receive any greater payment under either such Section than the Bank
granting such participation would have been entitled to receive in connection
with the rights transferred. Any agreement pursuant to which any Bank may grant
such a participating interest shall provide that such Bank shall retain the sole
right and responsibility to enforce the obligations of the Borrower hereunder,
including, without limitation, the right to approve any amendment, modification
or waiver of any provision of this Agreement; provided that such participation
agreement may provide that such Bank will not agree to any modification,
amendment or waiver of this Agreement that would (A) increase the Credit
Facility Commitment of such Bank if such increase would also increase the
participant's obligations, (B) forgive any amount of or postpone the date for
payment of any principal of or interest on any Loan or of any fee payable
hereunder in which such participant has an interest or (C) reduce the stated
rate at which interest or fees in which such participant has an interest accrue
hereunder.

     Section 11.12 Assignment of Commitments by Banks.

          (a) Each Bank shall have the right at any time, with the written
     consent (except in the case of an assignment to (i) an Affiliate of such
     Bank, (ii) another Bank or (iii) as provided in clause (b) below) of the
     Borrower and Agent (which consent shall not be unreasonably withheld), to
     assign all or any part of its Credit Facility Commitment (including the
     same percentage of its Note and outstanding Loans) to one or more other
     Persons; provided that such assignment is in an amount of at least
     $10,000,000 or the entire Credit Facility Commitment of such Bank, and if
     such assignment is not for such Bank's entire Credit Facility Commitment
     then such Bank's Credit Facility Commitment after giving effect to such
     assignment shall not be less than $10,000,000; and provided further that
     neither the consent of the Borrower nor of the Agent shall be required for
     any Bank to assign all or part of its Credit Facility Commitment to any
     Affiliate of the assigning Bank. Each such assignment shall set forth the
     assignee's address for

                                       42

<PAGE>   47
     notices to be given under Section 11.8 hereof hereunder and its designated
     Lending Office pursuant to Section 9.4 hereof. Upon any such assignment,
     delivery to the Agent of an executed copy of such assignment agreement and
     the forms referred to in Section 11.1 hereof, if applicable, and, except in
     the case of an assignment to an Affiliate of the assigning Bank, the
     payment of a $3,500 recordation fee to the Agent, the assignee shall become
     a Bank hereunder, all Loans and the Credit Facility Commitment it thereby
     holds shall be governed by all the terms and conditions hereof and the Bank
     granting such assignment shall have its Credit Facility Commitment, and its
     obligations and rights in connection therewith, reduced by the amount of
     such assignment; provided, however, in the event a Bank assigns all of its
     Credit Facility Commitment to an Affiliate or at the request of the
     Borrower, pursuant to Section 11.13(iii), no recordation fee shall be
     required hereunder. Notwithstanding any other provision set forth in this
     Agreement, any Bank may at any time create a security interest in all or
     any portion of its rights under this Agreement (including, without
     limitation, the Loans owing to it and the Note held by it) in favor of any
     Federal Reserve Bank in accordance with Regulation A of the Board of
     Governors of the Federal Reserve System.

          (b) Notwithstanding anything to the contrary contained herein, any
     Bank (a "Granting Bank") may grant to a special purpose funding vehicle (a
     "SPC"), identified as such in writing from time to time by the Granting
     Bank to the Agent and the Borrower, the option to provide to the Borrower
     all or any part of any Loan that such Granting Bank would otherwise be
     obligated to make to the Borrower pursuant to this Agreement; provided that
     (i) nothing herein shall constitute a commitment by any SPC to make any
     Loan, (ii) if an SPC elects not to exercise such option or otherwise fails
     to provide all or any part of such Loan, the Granting Bank shall be
     obligated to make such Loan pursuant to the terms hereof. The making of an
     Loan by an SPC hereunder shall utilize the Commitment of the Granting Bank
     to the same extent, and as if, such Loan were made by such Granting Bank.
     Each party hereto hereby agrees that no SPC shall be liable for any
     indemnity or similar payment obligation under this Agreement (all liability
     for which shall remain with the Granting Bank). In furtherance of the
     foregoing, each party hereto hereby agrees (which agreement shall survive
     the termination of this Agreement) that, prior to the date that is one year
     and one day after the payment in full of all outstanding commercial paper
     or other senior indebtedness of any SPC, it will not institute against, or
     join any other person in instituting against, such SPC any bankruptcy,
     reorganization, arrangement, insolvency or liquidation proceedings under
     the laws of the United States or any State thereof. In addition,
     notwithstanding anything to the contrary contained in this Section
     11.12(b), any SPC may (i) with notice to, but without the prior written
     consent of, the Borrower and the Agent and without paying any processing
     fee therefore, assign all or a portion of its interests in any Loans to the
     Granting Bank or to any financial institutions (consented to by the
     Borrower and Agent) providing liquidity and/or credit support to or for the
     account of such SPC to support the funding or maintenance of Loans and (ii)
     disclose on a confidential basis any non-public information relating to its
     Loans to any rating agency,

                                       43

<PAGE>   48

     commercial paper dealer or provider of any surety, guarantee or credit or
     liquidity enhancement to such SPC. This section may not be amended without
     the written consent of the SPC.

     Section 11.13 Amendments. Any provision of the Credit Documents may be
amended or waived if, but only if, such amendment or waiver is in writing and is
signed by (a) the Borrower, (b) the Required Banks, and (c) if the rights or
duties of the Agent are affected thereby, the Agent; provided that:

          (a) no amendment or waiver pursuant to this Section 11.13 shall (A)
     increase any Credit Facility Commitment of any Bank without the consent of
     such Bank or (B) reduce the stated rate at which interest or fees accrue or
     reduce the amount of or postpone any fixed date for payment of any
     principal of or interest on any Loan or of any fee payable hereunder
     without the consent of each Bank; and

          (b) no amendment or waiver pursuant to this Section 11.13 shall,
     unless signed by each Bank, change this Section 11.13, or the definition of
     Required Banks, or affect the number of Banks required to take any action
     under the Credit Documents.

     If the Borrower requests an amendment to this Agreement which requires the
approval of all of the Banks and one of the Banks (a "Replaceable Bank") does
not approve it, the Borrower may propose that another bank which is reasonably
acceptable to the Agent (a "Replacement Bank") be substituted for and replace
the Replaceable Bank for purposes of this Agreement. If a Replacement Bank is so
substituted for the Replaceable Bank, the Replaceable Bank shall enter into an
assignment agreement with the Replacement Bank, the Borrower and the Agent to
assign and transfer to the Replacement Bank, the Replaceable Bank's Credit
Facility Commitment hereunder, which shall provide, among other things, for the
payment of all Obligations owing to the Replaceable Bank; provided, however, if
a Replacement Bank cannot be found, then the Borrower may elect to take out the
Replaceable Bank and reduce the facility accordingly by making a prepayment in
the amount of such Replaceable Bank's outstanding Loans plus all accrued and
unpaid interest thereon and all fees and all other Obligations due and owing to
the Replaceable Bank on the date of replacement. Notwithstanding anything to the
contrary contained herein, in no event shall the Agent be a Replaceable Bank.

     Section 11.14 Headings. Section headings used in this Agreement are for
reference only and shall not affect the construction of this Agreement.

     Section 11.15 Legal Fees, Other Costs and Indemnification. The Borrower
agrees to pay all reasonable costs and expenses of the Agent in connection with
the preparation and negotiation of the Credit Documents, including, without
limitation, the reasonable fees and disbursements of counsel to the Agent, in
connection with the preparation and execution of the Credit Documents and any
amendment, waiver or consent related hereto, whether or not the transactions
contemplated herein are consummated. The Borrower further agrees to indemnify
each Bank, the Agent, and their

                                       44

<PAGE>   49

respective Affiliates, directors, agents, officers and employees, against all
losses, claims, damages, penalties, judgments, liabilities and expenses
(including, without limitation, all expenses of litigation or preparation
therefore, whether or not the indemnified Person is a party thereto) which any
of them may incur or reasonably pay arising out of or relating to any Credit
Document or any of the transactions contemplated thereby or the direct or
indirect application or proposed application of the proceeds of any Loan other
than those which arise from the gross negligence or willful misconduct of the
party claiming indemnification. The Borrower, upon demand by the Agent or a Bank
at any time, shall reimburse the Agent or Bank for any reasonable legal or other
expenses incurred in connection with investigating or defending against any of
the foregoing except if the same is directly due to the gross negligence or
willful misconduct of the party to be indemnified.

     Section 11.16 Entire Agreement. The Credit Documents constitute the entire
understanding of the parties thereto with respect to the subject matter thereof
and any prior or contemporaneous agreements, whether written or oral, with
respect thereto are superseded thereby.

     Section 11.17 Construction. The parties hereto acknowledge and agree that
neither this Agreement nor the other Credit Documents shall be construed more
favorably in favor of one than the other based upon which party drafted the
same, it being acknowledged that all parties hereto contributed substantially to
the negotiation of this Agreement and the other Credit Documents.

     Section 11.18 Governing Law. This Agreement and the other Credit Documents,
and the rights and duties of the parties hereto, shall be construed and
determined in accordance with the internal laws of the State of New York.

     Section 11.19 Submission to Jurisdiction; Waiver of Jury Trial. Each of the
Borrower, each Bank and the Agent hereby submits to the nonexclusive
jurisdiction of the United States District Court for the Southern District of
New York and of any New York State court sitting in the City of New York for
purposes of all legal proceedings arising out of or relating to this Agreement,
the other Credit Documents or the transactions contemplated hereby or thereby.
Each of the Borrower, each Bank and the Agent irrevocably waives, to the fullest
extent permitted by law, any objection which it may now or hereafter have to the
laying of the venue of any such proceeding brought in such a court and any claim
that any such proceeding brought in such a court has been brought in an
inconvenient forum. Each of the Borrower, each Bank and the Agent hereby
irrevocably waives any and all right to trial by jury in any legal proceeding
arising out of or relating to any Credit Document or the transactions
contemplated thereby.

                                                              ____________, 2000

     For Value Received, the undersigned, NRG Energy, Inc., a Delaware
corporation (the "Borrower"), promises to pay to the order of (the "Bank") on
the Maturity Date of the hereinafter defined Credit Agreement, at the principal
office of _____________ in New York, New York, in U.S. Dollars, the aggregate
unpaid principal amount of all Loans made by the Bank to the Borrower pursuant
to the Credit Agreement, together with interest on the principal amount of each
Loan from time to time outstanding hereunder at the rates, and payable in the
manner and on the dates, specified in the Credit Agreement.

     The Bank shall record on its books or records or on a schedule attached to
this Note, which is a part hereof, each Loan made by it pursuant to the Credit
Agreement, together with all payments of principal and interest and the
principal balances from time to time outstanding hereon, whether the Loan is a
Base Rate Loan or a Eurocurrency Loan, the interest rate and Interest Period
applicable thereto, provided that prior to the transfer of this Note all such
amounts shall be recorded on a schedule attached to this Note. The record
thereof, whether shown on such books or records or on a schedule to this Note,
shall be prima facie evidence of the same, provided, however, that the failure
of the Bank to record any of the foregoing or any error in any such record shall
not limit or otherwise affect the obligation of the Borrower to repay all Loans
made to it pursuant to the Credit Agreement together with accrued interest
thereon.

     This Note is one of the Notes referred to in the Credit Agreement dated as
of _________, 2000, among the Borrower, ________________, as Agent, and the
Banks party thereto (the "Credit Agreement"), and this Note and the holder
hereof are entitled to all the benefits provided for thereby or referred to
therein, to which Credit Agreement reference is hereby made for a statement
thereof. All defined terms used in this Note, except terms otherwise defined
herein, shall have the same meaning as in the Credit Agreement. This Note shall
be governed by and construed in accordance with the internal laws of the State
of New York.

     Prepayments may be made hereon and this Note may be declared due prior to
the expressed maturity hereof, all in the events, on the terms and in the manner
as provided for in the Credit Agreement.

     The Borrower hereby waives demand, presentment, protest or notice of any
kind hereunder.

                FORM OF LEGAL OPINION OF COUNSEL TO THE BORROWER

                         [DATE OF INITIAL DISBURSEMENT]

------------,
in its capacity as
Agent, and the Banks party to the Credit Agreement referred to below

Ladies and Gentlemen:

     I am Vice President and General Counsel of NRG Energy, Inc., a Delaware
corporation ("Borrower"), and have represented the Borrower in connection with
the transactions to be effected pursuant to the terms and conditions of that
certain Credit Agreement dated as of the date hereof among the Borrower, the
Banks party thereto and __________________, as Agent (the "Credit Agreement").

     This opinion is delivered to you pursuant to Section 6.1(a) of the Credit
Agreement. Capitalized terms used in this opinion and not otherwise defined
herein shall have the meanings ascribed thereto in the Credit Agreement.

     In connection with this opinion I have examined:

     A. the Credit Agreement; and

     B. the Notes.

     The foregoing documents, together with the other documents executed and
delivered by the Borrower to the Agent in connection with the Credit Agreement,
are sometimes referred to herein as the "Loan Documents."

     I have also examined such corporate documents and records of the Borrower
and such certificates of public officials and officers of the Borrower as I have
deemed necessary or appropriate for purposes of rendering this opinion. In
stating my opinion, I have assumed the genuineness of all signatures (except the
Borrower), the authority of persons signing the Loan Documents on behalf of all
parties thereto (except the Borrower), the authenticity of all documents
submitted to us as originals and the conformity to authentic original documents
of all documents submitted to us as certified, conformed or photostatic copies.

     Based on the foregoing, and subject to the qualifications set forth herein,
I am of the opinion that:

     1. The Borrower is a corporation duly organized, validly existing and in
good standing under the laws of the State of Delaware.

                                      C-1

<PAGE>   60

     2. The Borrower has the corporate power and authority to execute, deliver
and perform the Loan Documents and all corporate action necessary to authorize
the execution, delivery and performance of the Loan Documents has been taken.

     3. The Loan Documents have been duly executed and delivered on behalf of
the Borrower and constitute valid and binding obligations of the Borrower
enforceable against the Borrower in accordance with their respective terms,
except as limited by applicable bankruptcy, insolvency, moratorium or other
similar laws affecting the rights of creditors or the application of general
principles of equity (whether considered in a proceeding in equity or at law).

     4. The execution, delivery and performance by the Borrower of the Loan
Documents do not: (i) result in a breach or other violation of any of the terms,
conditions or provisions of any indenture, loan or credit agreement or any other
agreement, lease or instrument to which the Borrower is a party or by which it
or any of its properties may be bound; (ii) result in a breach or other
violation of any of the terms, conditions or provisions of any order, writ,
injunction or decree of any court or other governmental authority or
instrumentality to which the Borrower is subject; or (iii) result in the
creation or imposition of any lien, charge, security interest or encumbrance
upon any property of the Borrower under any indenture, loan or credit agreement
or any other material agreement, lease, instrument, order, writ, injunction or
decree referred to in clauses (i) and (ii) above; where any such breach,
violation or lien could have a Material Adverse Effect. The execution, delivery
and performance by the Borrower of the Loan Documents and the transactions
contemplated thereby do not result in a breach or other violation of any of the
terms, conditions or provisions of any applicable federal, or Delaware statute
or regulation where such breach or violation could have a Material Adverse
Effect.

     5. Except as set forth on Schedule 5.5 to the Credit Agreement, no
judgments are outstanding against the Borrower, nor is there pending or, to the
best of our knowledge, threatened, any litigation, investigation, contested
claim or governmental proceeding by or against the Borrower which could have a
Material Adverse Effect.

     6. Neither the Borrower nor any Subsidiary is an "investment company"
within the meaning of the Investment Company Act of 1940, as amended. No
approvals by the SEC under the Public Utility Holding Company Act of 1935, as
amended ("PUHCA") are required in connection with the execution by the Borrower
of the Loan Documents or the performance by the Borrower of any of the
transactions contemplated thereby.

     7. No authorization, consent, license, order or approval of, or other
action by, any governmental authority is required to be obtained or made in
connection with the due execution, delivery and performance of the Loan
Documents.

I am a member of the bar of the State of Minnesota, and I am not licensed to
practice in the States of Delaware or New York. I express no opinion on the law
of any other jurisdiction other than the State of Minnesota and the provisions
of the Delaware General

                                      C-2

<PAGE>   61

Corporation Law and the federal laws of the United States applicable therein or
thereto. The opinions expressed herein are based upon the law and circumstances
as they are in effect or exist on the date hereof, and I assume no obligation to
revise or supplement this letter in the event of future changes in the law or
interpretations thereof with respect to circumstances or events that may occur
subsequent to the date hereof. I express no opinion as to the effect of the laws
of any other jurisdiction.

     For purposes of the opinion rendered in paragraph 3, I have assumed that
the laws of the State of New York are substantially the same as the laws of the
State of Minnesota.

     Minnesota Statutes ss.290.371, Subd. 4, provides that any corporation
required to file a Notice of Business Activities Report does not have a cause of
action upon which it may bring suit under Minnesota law unless the corporation
has filed a Notice of Business Activities Report and provides that the use of
the courts of the State of Minnesota for all contracts executed and all causes
of action that arose before the end of any period for which a corporation failed
to file a required report is precluded. Insofar as our opinion may relate to the
valid, binding and enforceable character of any agreement under Minnesota law or
in a Minnesota court, we have assumed that any party seeking to enforce such
agreement has at all times been, and will continue at all times to be, exempt
from the requirement of filing a Notice of Business Activities Report or, if not
exempt, has duly filed, and will continue to duly file, all Notice of Business
Activities Reports.

     This opinion is furnished by me as General Counsel of the Borrower to you
pursuant to the Credit Agreement. This opinion is solely for your benefit and
may not be relied upon by any other Person or by you in any other context, or
any other Person that may become a Bank under the Credit Agreement after the
date hereof. This opinion may not be quoted, in whole or in part, or copies
hereof furnished, to any other Person, or any other Person that may become a
Bank under the Credit Agreement after the date hereof without my prior express
written consent.

                                        Very truly yours,

                                      C-3

                   LITIGATION/GOVERNMENTAL PROCEEDINGS SUMMARY

Fortistar (Oswego)

In July 1999, Fortistar Capital, Inc. ("Fortistar") commenced an action against
NRG Energy, Inc. (the "Company") in Hennepin County (Minnesota) District Court,
seeking damages in excess of $100 million and an order restraining the Company
from consummating the acquisition of Niagara Mohawk Power Corporation's Oswego
generating station. Fortistar's motion for a temporary restraining order was
denied. A temporary injunction hearing was held in September 1999. The
acquisition was consummated in October 1999. In January 2000, the court denied
Fortistar's request for a temporary injunction. In April and December 2000, the
Company filed summary judgment motions to dispose of the litigation respecting
both liability and damages, and a hearing on these motions was held in April
2001 and certain of Fortistar's claims were dismissed. No trial date has been
set in respect of the remaining claims. The Company has asserted numerous
counterclaims against Fortistar and will continue to vigorously defend the suit.

New York Environmental Investigation

In May 2000, the New York Department of Environmental Conservation issued a
Notice of Violation to the Company and the prior owner of the Company's Huntley
and Dunkirk facilities in New York, relating to physical changes made at those
facilities prior to our assumption of ownership. The Notice of Violation alleges
that these changes represent major modifications undertaken without the proper
permits having been obtained. Although the Company has a right to
indemnification by the previous owner for fines, penalties, assessments and
related losses resulting from the previous owner's failure to comply with
environmental laws and regulations, if these facilities did not comply with the
applicable permit requirements, the Company could be required, among other
things, to install specified pollution control technology to further reduce
pollutant emissions from the Huntley and Dunkirk facilities, and the Company
could become subject to fines and penalties associated with the current and
prior operation of the facilities. The Company is currently in settlement
discussions with the Department of Environmental Conservation and the State
Attorney General's Office. On May 14, 2001, the Company received a Notice of
Intent to Sue from the New York Attorney General, notifying the Company pursuant
to Section 304 of the Clean Air Act (the "Act") of the State's intent to file
suit against the Company and Niagara Mohawk Power Corporation in federal
district court for violations of the Act, unless a settlement is reached within
60 days. The Company will continue its settlement discussions with the Attorney
General's Office and the Department of Environmental Conservation.

California Actions

The Company has been named as a defendant in certain private plaintiff class
actions filed in the Superior Court of the State of California for the County of
San

Diego in San Diego, California on November 27, 2000 (Pamela R. Gordon v. Reliant
Energy, Inc., et al.) and November 29, 2000 (Ruth Hendricks v. Dynegy Power
Marketing Inc., et al.), and in the Superior Court of the State of California,
City and County of San Francisco (Pier 23 Restaurant v. PG&E Energy Trading, et
al., filed January 24, 2001). The Company has also been named in another suit
filed on January 16, 2001 in the Superior Court of the State of California for
the County of San Diego, brought by three California water districts, as
consumers of electricity (Sweetwater Authority v. Dynegy Inc., et al.), and in a
suit filed on January 18, 2001 in Superior Court of the State of California,
County of San Francisco, brought by the San Francisco City Attorney on behalf of
the People of the State of California (The People of the State of California v.
Dynegy Power Marketing, Inc., et al.). Although the complaints contain a number
of allegations, the basic claim is that, by underbidding forward contracts and
exporting electricity to surrounding markets, the defendants, acting in
collusion, were able to drive up wholesale prices on the Real Time and
Replacement Reserve markets, through the Western Systems Coordinating Council
and otherwise. The complaints allege that the conduct violated California
antitrust and/or unfair competition laws. The Company does not believe that it
has engaged in any illegal activities, and intends to vigorously defend these
lawsuits.

On May 2, 2001, certain partially-owned subsidiaries of the Company, and other
power generators and power traders, were named as defendants in a class action
filed in the Superior Court of the State of California for the County of Los
Angeles (Cruz M. Bustamante and Barbara Matthews v. Dynegy, Inc., et al.). The
complaint alleges that defendants engaged in various anti-competitive, unlawful,
fraudulent and unfair business practices and acts, and acted with the
anti-competitive purpose of using economic and physical withholding of
electricity from the California electric generation market in order to derive
monopoly profits from the sale of their electricity in California. The Company
does not believe that its affiliates named in this lawsuit engaged in any
illegal activities, and the Company's affiliates intend to vigorously contest
these allegations.

LABOR DISPUTE SUMMARY
