WHEREAS:

                  A. The Projects comprise five natural gas-fired electric
         generation facilities located in Louisiana and Illinois. The electric
         generation facilities comprising the Projects are peaker facilities
         designed to generate electricity during periods of peak demand for
         electricity. As of the date hereof, the Big Cajun I Units 3&4 Project,
         the Rockford I Project and the Sterlington Project are complete and
         operate commercially. The Rockford II Project and the Bayou Cove
         Project are guaranteed by NRG Energy pursuant to the Contingent
         Guaranty Agreement to be completed and commercially operating by June
         30, 2003.

                  B. Each Project is owned by an indirect wholly-owned
         subsidiary of NRG Energy. The Issuer is an indirect wholly-owned
         subsidiary of NRG Energy.

                  C. The Issuer will issue and sell its Series A Bonds in an
         offering in reliance on Rule 144A and Regulation S under the Securities
         Act and will use the proceeds from the sale of the Series A Bonds to
         make loans to three of the five Project Companies pursuant to and in
         accordance with the Project Loan Agreements. Such Project Companies
         will use the proceeds of the sale of the Series A Bonds lent to them
         pursuant to the Project Loan Agreements to (i) reimburse NRG Energy for
         NRG Energy's costs of having constructed and/or acquired the Projects
         (including interest incurred during construction), (ii) pay the
         Premium, (iii) deposit $11,279,588 on the Closing Date into the
         Collateralized Experience Account, and (iv) pay transaction fees and
         costs in connection with the Transaction.

                  D. The Issuer will pay the principal of and interest on the
         Series A Bonds in accordance with the terms of the Indenture.

                  E. The Issuer will enter into the Swap Agreement with the Swap
         Counterparty pursuant to which the Issuer will make fixed rate interest
         rate payments to the Swap Counterparty and the Swap Counterparty will
         make floating rate interest payments to the Issuer.


<PAGE>

                  F. Regularly scheduled payments of principal of and interest
         on the Series A Bonds will be unconditionally and irrevocably
         guaranteed by XLCA pursuant to, and subject to, the Policy and the
         Insurance and Reimbursement Agreement in exchange for the payment of
         the Premium by the Issuer to XLCA as set forth in the Premium Letter.

                  G. Regularly scheduled payments of Swap Payment Amounts will
         be unconditionally and irrevocably guaranteed by XLCA pursuant to, and
         subject to, the Swap Policy and the Insurance and Reimbursement
         Agreement in exchange for the payment of the Swap Policy Premium by the
         Issuer to XLCA as set forth in the Premium Letter.

                  H. Pursuant to and in accordance with the Contingent Guaranty
         Agreement, NRG Energy will be obligated to make certain payments under
         circumstances specified in the Contingent Guaranty Agreement.

                  I. Pursuant to and in accordance with the Insurance and
         Reimbursement Agreement, the Issuer will be obligated to reimburse XLCA
         in respect of payments (if any) made by XLCA pursuant to the Policy
         and/or the Swap Policy and in respect of other amounts specified in the
         Insurance and Reimbursement Agreement.

                  J. Pursuant to the Issuer Collateral Documents, the Issuer's
         obligations owed to the Secured Parties will be secured by a first
         priority lien for the benefit of the Secured Parties on the membership
         interests in the Issuer and all of the property and assets of the
         Issuer (including the Project Loan Notes).

                  K. Pursuant to the Guaranties, each of the Project Companies
         will unconditionally and irrevocably guaranty the obligations and
         indebtedness of the Issuer in respect of the Guaranteed Obligations,
         which Guaranties will, pursuant to the Project Company Collateral
         Documents, be secured by a first priority lien for the benefit of the
         Secured Parties on the membership interests in each Project Company
         (other than the Big Cajun Project Company and the Sterlington Project
         Company) and on all or substantially all of the property and assets of
         each Project Company.

extent the same are being contested in good faith by appropriate proceedings and
adequate reserves with respect thereto shall, to the extent required by GAAP,
have been set aside, and failure to pay or comply with the contested item could

shall the Issuer not be a party to such an interest rate swap agreement,
provided, however, that the Issuer's obligations to enter into a Replacement
Swap Agreement pursuant to this Section 2.11 shall be expressly conditioned upon
XLCA's agreement to provide a financial guaranty to the replacement swap
provider on the same or similar terms as the Swap Policy. The Issuer shall be
required to apply any amounts received from any replacement swap provider in
connection with the Issuer's entry into a Replacement Swap Agreement (a) first,
toward the satisfaction of any Swap Breakage Costs due and owing to the original
Swap Counterparty under the Swap Agreement, and (b) second, to reimburse XLCA
for any payments made under the Swap Policy constituting termination payments in
connection with an early termination of the Swap Agreement to the extent not
previously reimbursed. The Issuer shall terminate or partially terminate the
Swap Agreement, in each case subject to its terms and conditions, such that at
no time shall the aggregate notional amount under the Swap Agreement exceed the
then outstanding aggregate principal amount of the Series A Bonds.

and substance reasonably satisfactory to Collateral Agent encumbering such
right, title or interest by the Lien of such Mortgage, and (iii) obtain a

due all material Taxes and governmental charges imposed upon it or upon its

shall become delinquent or in default and before penalties accrue thereon,
unless and to the extent the same are being contested in good faith by
appropriate proceedings and adequate reserves with respect thereto shall, to the

repair, renew or replace such property if such property is no longer useful in
the conduct of its business and the failure to do so could not reasonably be
expected to have a Project Material Adverse Effect; provided that the covenant
set forth in this Section 3.12(c) shall not serve to prohibit any disposition of

result of such authentication, delivery, issuance or incurrence, (ii) each of
Moody's and S&P has confirmed in writing that such authentication, delivery,

         4.5 Distributions.

                  (a) The Issuer shall not directly or indirectly (i) make or
declare any distribution (in cash, property or obligation) on, or make any other
payment on account of, any equity interest in the Issuer, (ii) make any payment
in respect of Subordinated Debt or (iii) make any other payment from the
Distribution Account (whether to a Project Company, any Affiliate of the Issuer
or any Project Company or any other Person) (each such distribution or payment,
a "Restricted Payment") unless:

                  (i) no Issuer Event of Default, Issuer Inchoate Default or
         Project Event of Default pursuant to Section 7.2(n) of this Agreement
         (Interconnection Solution) has occurred and is continuing and such
         Restricted Payment will not result in an Issuer Event of Default or an
         Issuer Inchoate Default;

                  (ii) subject to any reduction in the amount of the Restricted
         Payment in accordance with Section 4.5(b) of this Agreement, the amount
         of such Restricted Payment is limited to, and such Restricted Payment
         is made from, Account Funds in the Distribution Account and in
         accordance with Section 4.6 of the Depositary Agreement;

                  (iii) the Restricted Payment is made on a Restricted Payment
         Date;

                  (iv) as of the Restricted Payment Date, the Available
         Collateralized Experience Funds equal or exceed the Collateralized
         Experience Amount as of such date; and

                  (v) the Issuer shall have delivered to Collateral Agent, the
         Trustee, the Swap Counterparty and XLCA, at least five Business Days
         prior to the proposed Restricted Payment Date, a certificate dated as
         of the proposed Restricted Payment Date and duly executed by a
         Responsible Officer of the Issuer, certifying to the effect that each
         of the foregoing conditions and the other applicable conditions of this
         Section 4.5 shall have been satisfied as of such date and XLCA (if it
         is the Controlling Party), acting in its absolute discretion, shall
         have confirmed in writing to the Collateral Agent XLCA's





                                       15
<PAGE>

         agreement with such certificate (provided that failure by XLCA to make
         such confirmation prior to the proposed Restricted Payment Date shall
         be deemed to be such confirmation).

                  (b) If there shall have occurred and be continuing a Project
Event of Default or an Inchoate Project Block Condition in respect of any
Project Company, the Issuer shall reduce the Restricted Payment to be made by it
pursuant to Section 4.5(a) of this Agreement by an amount equal to the Project
Company Blocked Amount for such Project Company. Subject to Section 4.5(d), such
Project Company Blocked Amount shall be deemed to be Account Funds in the
Distribution Account not disbursed within 30 days after an Annual Scheduled
Payment Date and, accordingly, the Collateral Agent shall direct the Depositary
Agent to promptly transfer such Project Company Blocked Amount to the Revenue
Account to be applied in accordance with the Depositary Agreement in the same
manner as Account Funds in the Distribution Account that are not disbursed in
accordance with Section 4.6.2 of the Depositary Agreement by the 30th day
following an Annual Scheduled Payment Date.

                  (c) Notwithstanding anything to the contrary in Section
4.5(a), if the Issuer is not permitted to make a Restricted Payment pursuant to
Section 4.5(a) on any Initial Restricted Payment Date solely because of an
Inchoate Block Condition:

                  (i) the amount of the Restricted Payment that the Issuer would
         have been permitted to make pursuant to Section 4.5(a) had no such
         Inchoate Block Condition been continuing on such Initial Restricted
         Payment Date (the "Blocked Restricted Payment Amount") shall not be
         transferred from the Distribution Account to the Revenue Account until
         the earlier of the end of the Subsequent Restricted Payment Period and
         the occurrence of an Issuer Event of Default (at which time the Blocked
         Restricted Payment Amount or any part thereof not previously applied as
         permitted by Section 4.5(c)(ii) shall be deemed to be Account Funds in
         the Distribution Account not disbursed within 30 days after an Annual
         Scheduled Payment Date and, accordingly, the Collateral Agent shall
         direct the Depositary Agent to promptly transfer the Blocked Restricted
         Payment Amount or such part thereof to the Revenue Account to be
         applied in accordance with the Depositary Agreement in the same manner
         as Account Funds in the Distribution Account that are not disbursed in
         accordance with Section 4.6.2 of the Depositary Agreement by the 30th
         day following an Annual Scheduled Payment Date); and

                  (ii) prior to the end of the Subsequent Restricted Payment
         Period, and only if such Inchoate Block Condition shall have been cured
         by, or on behalf of, the Issuer or shall have been waived by the
         Controlling Party prior to maturing into or becoming an Issuer Event of
         Default, the Issuer may use the Blocked Restricted Payment Amount to
         make a Restricted Payment; provided that the conditions set forth in
         Section 4.5(a)(i) through (v) are satisfied (the date upon which such
         payment is made, the "Subsequent Restricted Payment Date").

                  (d) Notwithstanding anything to the contrary in Section
4.5(b), if the Issuer is not permitted to make a Restricted Payment pursuant to
Section 4.5(b) on any Initial Restricted Payment Date solely because of an
Inchoate Project Block Condition:





                                       16
<PAGE>

                  (i) the Project Company Blocked Amount shall not be
         transferred from the Distribution Account to the Revenue Account until
         the earlier of the end of the Subsequent Project Restricted Payment
         Period and the occurrence of a Project Event of Default (at which time
         the Project Company Blocked Amount or any part thereof not previously
        applied as permitted by Section 4.5(d)(ii) shall be deemed to be
         Account Funds in the Distribution Account not disbursed within 30 days
         after an Annual Scheduled Payment Date and, accordingly, the Collateral
         Agent shall direct the Depositary Agent to promptly transfer the
         Project Company Blocked Amount or such part thereof to the Revenue
         Account to be applied in accordance with the Depositary Agreement in
         the same manner as Account Funds in the Distribution Account that are
         not disbursed in accordance with Section 4.6.2 of the Depositary
         Agreement by the 30th day following an Annual Scheduled Payment Date);
         and

                  (ii) prior to the end of the Subsequent Project Restricted
         Payment Period, and only if such Inchoate Project Block Condition shall
         have been cured by, or on behalf of, the relevant Project Company or
         shall have been waived by the Controlling Party prior to maturing into
         or becoming a Project Event of Default, the Issuer may use the Project
         Company Blocked Amount to make a Restricted Payment; provided that the
         conditions set forth in Section 4.5(a)(i) through (v) are satisfied
         (the date upon which such payment is made, the "Subsequent Project
         Restricted Payment Date").

                  (e) Even if all of the conditions set forth in Section 4.5(a)
or 4.5(b) of this Agreement have not been satisfied as of a proposed Restricted
Payment Date, the Issuer may make distributions ("Tax Distributions") for
Federal, state or local income tax payments in an amount not to exceed the
amount that the Issuer and the Project Companies would be required to pay if
such Persons were tax paying entities forming a consolidated group for Federal
income tax purposes or a similar consolidated, combined or unitary group for
state or local income tax purposes (the "Tax Group"), which amount shall be
assumed to equal the product of (A) the net income of the Tax Group for Federal,
state or local income tax purposes multiplied by (B) the highest marginal
Federal, state or local income tax rate at the time applicable to "C"
corporations; provided that the net income of the Tax Group shall be calculated
based on the assumption that the Tax Group is not part of any other consolidated
group (or similar group for state or local income tax purposes) and that all of
the Tax Group's tax attributes and benefits (including, without limitation,
deductions, credits, refunds, carryovers and carrybacks) shall be applied solely
with respect to the Tax Group's income; and provided, further, that no Tax
Distribution pursuant to this Section 4.5(e) shall be permitted, if an Issuer
Event of Default or Issuer Inchoate Default has occurred and is continuing or
would result from such Tax Distributions.

                  (f) Notwithstanding anything to the contrary in Section
4.5(e), if the Issuer is not permitted to make a Tax Distribution pursuant to
Section 4.5(e) solely because there shall be continuing an Issuer Inchoate
Default:

                  (i) the amount of the Tax Distribution that the Issuer would
         have been permitted to make pursuant to Section 4.5(e) had no such
         Issuer Inchoate Default been continuing (the "Tax Distribution Amount")
         shall not be transferred from the Distribution Account to the Revenue
         Account until the earlier of the end of the Subsequent Tax




                                       17
<PAGE>

         Payment Period and the occurrence of an Issuer Event of Default (at
         which time the Tax Distribution Amount or any part thereof not
         previously applied as permitted by Section 4.5(f)(ii) shall be deemed
         to be Account Funds in the Distribution Account not disbursed within 30
         days after an Annual Scheduled Payment Date and, accordingly, the
         Collateral Agent shall direct the Depositary Agent to promptly transfer
         the Tax Distribution Amount or such part thereof to the Revenue Account
         to be applied in accordance with the Depositary Agreement in the same
         manner as Account Funds in the Distribution Account that are not
         disbursed in accordance with Section 4.6.2 of the Depositary Agreement
         by the 30th day following an Annual Scheduled Payment Date); and

                  (ii) prior to the end of the Subsequent Tax Payment Period,
         and only if such Issuer Inchoate Default shall have been cured by, or
         on behalf of, the Issuer or shall have been waived by the Controlling
         Party prior to maturing into or becoming an Issuer Event of Default,
         the Issuer may use the Tax Distribution Amount to make a Tax
         Distribution in the amount set forth, and in the manner contemplated,
         in Section 4.5(e).

                  (g) Notwithstanding anything to the contrary herein or in any
other Financing Document, neither (i) Excluded Revenues nor (ii) amounts payable
to, or permitted to be disbursed to, NRG Energy pursuant to the Depositary
Agreement shall constitute Restricted Payments subject to this Section 4.5 and
such Excluded Revenues and amounts shall be permitted to be disbursed to NRG
Energy or any Affiliate thereof without regard for the conditions set forth in
this Section 4.5.

         4.6 Investments. The Issuer shall not make any investments (whether by
purchase of stocks, bonds, notes or other securities, loan, extension of credit,
advance or otherwise) other than (a) Permitted Investments made pursuant to
Section 5.1 of the Depositary Agreement, and (b) the investments provided for in
the Financing Documents.

         4.7 Transactions With Affiliates. The Issuer shall not enter into any

transaction or agreement) with any of its Affiliates other than (a) transactions
provided for in or expressly permitted by the Financing Documents, (b)
transactions or agreements certified by a Responsible Officer of the Issuer as
having terms that are not materially less favorable than the terms the Issuer
would obtain in an arm's-length transaction with a person that is not an
Affiliate, or (c) transactions or agreements between or among only the Issuer
and/or the Project Companies not otherwise prohibited by the terms of any
Financing Document.

         4.8 ERISA. The Issuer shall not establish, maintain, contribute to or
become obligated to contribute to any ERISA Plan.

         4.9 Liquidation; Amendment of Organizational Documents.

                  (a) The Issuer shall not liquidate or dissolve itself (or
suffer any liquidation or dissolution) or amend its organizational documents in
any material respect (except, in respect of such amendment of its organizational
documents, (i) as required to comply with the "special purpose entity"
requirements or similar criteria of any Rating Agency or (ii) in connection with
a Permitted Change of Control).

                  (b) Section 9.01 of the Indenture shall govern the Issuer's
rights in respect of the transactions expressly referred to in such Section 9.01
(and reference is made herein to Section 9.01(4) of the Indenture and the right
of XLCA (at any time when there is no Insurer Default) to consent, in its
absolute discretion, to any transaction referred to therein prior to its
consummation). Upon any consolidation of the Issuer with, or merger of the
Issuer into, any other Person in accordance with Section 9.01 of the Indenture,

merged or to which any conveyance, transfer or lease is made in accordance with
Section 9.01 of the Indenture shall succeed to, and be substituted for, and may
exercise every right and power of, the Issuer under this Agreement and the other
Financing Documents with the same effect as if such successor Person had been

change its fiscal year without XLCA's prior written consent.

         4.12 Assignment. The Issuer shall not assign its rights or obligations
hereunder or under any other Financing Documents, except as expressly permitted

permitted pursuant to paragraph (c) of this Section 5.8, Project Company shall
perform its obligations and exercise its rights under any such transaction or

                                       21
<PAGE>

         Counsel (as such term is defined in the Indenture), each stating that
         such consolidation, merger, conveyance, transfer or lease and, if a

                                       23
<PAGE>

Substance has occurred in, on, under or at such real property, that such Release

                                   ARTICLE 6
                                    GUARANTY

         6.1 Guaranty.

                  (a) Each Project Company, as primary obligor and not merely as
surety, absolutely, unconditionally and irrevocably and jointly and severally
with each other Project Company guarantees to the Secured Parties the full and
punctual payment when due, whether at stated maturity, by acceleration or
otherwise, of all of the Bond Obligations, the Reimbursement Obligations and the
Swap Obligations of the Issuer under the Financing Documents, together with the
payment in full of all fees and expenses incurred by the Collateral Agent or any
other Secured Party in enforcing any such Obligations or the terms hereof,
including reasonable fees and expenses of its legal counsel and agents
(collectively, the "Guaranteed Obligations"), and agrees that if, for any
reason, the Issuer shall fail to pay when due any of the Guaranteed Obligations,
such Project Company will pay the same forthwith. Each Project Company waives
notice of acceptance of its Guaranty and of any obligation to which it applies
or may apply under the terms hereof, and waives promptness, diligence,
presentment, demand of payment or performance, notice of dishonor or non-payment
or non-performance, protest, or notice of protest, of any such obligations, suit
or taking other action by any Secured Party against, and




                                       24
<PAGE>

giving any notice of default or other notice to, or making any demand on, any
party liable thereon (including any Project Company).

                  (b) If, notwithstanding the representation and warranty set
forth in Section 2.2(aa) of the Insurance and Reimbursement Agreement or
anything to the contrary herein, enforcement of the liability of any Project
Company under its Guaranty for the full amount of the Guaranteed Obligations
would be an unlawful or voidable transfer under any applicable fraudulent
conveyance or fraudulent transfer law or any comparable law, then the liability
of such Project Company hereunder shall be reduced to the highest amount for
which such liability may then be enforced without giving rise to an unlawful or
voidable transfer under any such law.

         6.2 Guaranty Absolute. The Guaranty of each Project Company is a
primary obligation of such Project Company and is an absolute, unconditional,
continuing and irrevocable guaranty of payment in full in cash of the Guaranteed
Obligations and not of collectibility, and is in no way conditioned on or
contingent upon any attempt to enforce in whole or in part the Issuer's
liabilities and obligations to the Secured Parties. If the Issuer shall fail to
pay in full in cash any of the Guaranteed Obligations to any Secured Party as
and when they are due, the Project Companies shall forthwith pay such Guaranteed
Obligations immediately (in immediately available funds in Dollars) to an
account designated by the Collateral Agent. Each failure by the Issuer to pay
any Guaranteed Obligation strictly in accordance with the terms of each
Financing Document under which such Guaranteed Obligation arises, regardless of
any Legal Requirement now or hereafter in effect in any jurisdiction, shall give
rise to a separate cause of action herewith, and separate suits may be brought
hereunder as each cause of action arises.

         6.3 Rights and Obligations Absolute and Unconditional. All rights of
the Secured Parties and all obligations of each Project Company in respect of
its Guaranty hereunder shall be absolute and unconditional irrespective of:

                  (a) any lack of validity, legality or enforceability of any
Financing Document;

                  (b) the failure of any Secured Party:

                  (i) to assert any claim or demand or to enforce any right or
         remedy against the Issuer, any Project Company or any other Person
         (including any other guarantor) under the provisions of any Financing
         Document or otherwise, or

                  (ii) to exercise any right or remedy against any other
         guarantor of, or collateral securing, any of the Obligations;

                  (c) any change in the time, manner or place of payment of, or
in any other term of, any of the Obligations, or any other extension or renewal
of any obligation of the Issuer or any Project Company;

                  (d) any reduction, limitation, impairment or termination of
any of the Obligations for any reason (other than the written agreement of all
of the Secured Parties to terminate the Obligations in full), including any
claim of waiver, release, surrender, alteration or compromise, and shall not be
subject to, and Project Company hereby waives any right to or




                                       25
<PAGE>

claim of, any defense or setoff, counterclaim, recoupment or termination
whatsoever by reason of the invalidity, illegality, nongenuineness,
irregularity, compromise, unenforceability of, or any other event or occurrence
affecting, any obligation of the Issuer, any Project Company or otherwise, other
than Project Company's indefeasible payment in full of the Guaranteed
Obligations;

                  (e) any amendment to, rescission, waiver or other modification
of, or any consent to departure from, any of the terms of any Financing Document
other than its Guaranty;

                  (f) any addition, exchange, release, surrender or
non-perfection of any collateral, or any amendment to or waiver or release or
addition of, or consent to departure from, any other security interest held by
any Secured Party securing any of the Obligations;

                  (g) any sale, exchange, release or surrender of, realization
upon or other manner or order of dealing with any property by whomsoever pledged
or mortgaged to secure or howsoever securing the Obligations or any liabilities
or obligations (including any of those hereunder) incurred directly or
indirectly in respect thereof or hereof and/or any offset there against;

                  (h) the application of any sums by whomsoever paid or
howsoever realized to any obligations and liabilities of the Issuer or any
Project Company to the Secured Parties under the Financing Documents in the
manner provided therein regardless of what obligations and liabilities remain
unpaid;

                  (i) any action or failure to act in any manner referred to in
this Guaranty which may deprive Project Company of its right to subrogation
against the Issuer or any other Project Company to recover full indemnity for
any payments or performances made pursuant to its Guaranty or of its right of
contribution against any other party; or

                  (j) any other circumstance which might otherwise constitute a
defense available to, or a legal or equitable discharge of, the Issuer, any
Project Company, any surety or any guarantor.

         6.4 Guaranty Continuing. Each Project Company's Guaranty is a
continuing Guaranty and all obligations to which it applies or may apply under
the terms hereof shall be conclusively presumed to have been created in reliance
hereon. In the event that, notwithstanding the provisions of Section 6.1, any
Project Company's Guaranty shall be deemed revocable in accordance with
applicable Legal Requirements, then any such revocation shall become effective
only upon receipt by the Collateral Agent of written notice of revocation signed
by such Project Company. No revocation or termination hereof shall affect in any
manner rights arising under any Project Company's Guaranty with respect to
Guaranteed Obligations arising prior to receipt by the Collateral Agent of
written notice of such revocation or termination.

         6.5 Waivers. Each Project Company hereby waives and relinquishes all
rights and remedies accorded by applicable law to sureties or guarantors and
agrees not to assert or take advantage of any such rights or remedies, including
(a) any right to require the Collateral Agent or any other Secured Party to
proceed against the Issuer, any Project Company or any other Person or to
proceed against or exhaust any security held by the Collateral Agent or any
other




                                       26
<PAGE>

Secured Party at any time or to pursue any other remedy in the Collateral
Agent's or any other Secured Party's power before proceeding against such
Project Company, (b) any defense that may arise by reason of the incapacity,
lack of power or authority, dissolution, merger, termination or disability of
the Issuer, any Project Company or any other Person or the failure of the
Collateral Agent or any other Secured Party to file or enforce a claim against
the estate (in administration, bankruptcy or any other proceeding) of the
Issuer, any Project Company or any other Person, (c) demand, presentment,
protest and notice of any kind except as provided herein, including notice of
the existence, creation or incurring of any new or additional indebtedness or
obligation or of any action or non-action on the part of the Issuer, any Project
Company, the Collateral Agent, any other Secured Party, any endorser or creditor
of the Issuer, any Project Company or on the part of any other Person under this
or any other instrument in connection with any obligation or evidence of
indebtedness held by the Collateral Agent or any other Secured Party as
collateral or in connection with any Guaranteed Obligation, (d) any defense
based upon an election of remedies by the Collateral Agent or any other Secured
Party, including an election to proceed by non-judicial rather than judicial
foreclosure, which destroys or otherwise impairs the subrogation rights of any
Project Company, the right of any Project Company to proceed against the Issuer
or any other Project Company for reimbursement, or both, (e) any defense based
on any offset against any amounts which may be owed by any Person to any Project
Company for any reason whatsoever, (f) any defense based on any act, failure to
act, delay or omission whatsoever on the part of the Issuer or any Project
Company or the failure by the Issuer or any Project Company to do any act or
thing or to observe or perform any covenant, condition or agreement to be
observed or performed by it under the Financing Documents, (g) any defense based
upon any statute or rule of law which provides that the obligation of a surety
must be neither larger in amount nor in other respects more burdensome than that
of the principal; provided that, upon payment or performance in full of the
Guaranteed Obligations, a Project Company's Guaranty shall no longer be of any
force or effect, (h) any defense, setoff or counterclaim which may at any time
be available to or asserted by the Issuer or any Project Company against the
Collateral Agent, any other Secured Party or any other Person under the
Financing Documents, (i) any duty on the part of the Collateral Agent or any
other Secured Party to disclose to any Project Company any facts the Collateral
Agent or any other Secured Party may now or hereafter know about the Issuer or
any Project Company, regardless of whether the Collateral Agent or such Secured
Party have reason to believe that any such facts materially increase the risk
beyond that which any Project Company intends to assume, or have reason to
believe that such facts are unknown to any Project Company, or have a reasonable
opportunity to communicate such facts to any Project Company, since each Project
Company acknowledges that it is fully responsible for being and keeping informed
of the financial condition of the Issuer and the Project Companies and of all
circumstances bearing on the risk of non-payment or non-performance of any
obligations and liabilities hereby guaranteed, (j) any defense based on any
change in the time, manner or place of any payment or performance under, or in
any other term of, the Financing Documents or any other amendment, renewal,
extension, acceleration, compromise or waiver of or any consent or departure
from the terms of the Financing Documents, (k) any defense arising because of
the Collateral Agent's or any other Secured Party's election, in any proceeding
instituted under the Federal Bankruptcy Code, of the application of Section
1111(b)(2) of the Federal Bankruptcy Code, and (l) any defense based upon any
borrowing or grant of a security interest under Section 364 of the Federal
Bankruptcy Code.



                                       27

         6.6 Acknowledgments. Each Project Company acknowledges that it has been
provided with a copy of each of the Financing Documents and has read and is
familiar with the provisions of each of the Financing Documents.

         6.7 Subordination. All existing and future indebtedness of, or other
obligation owed by, the Issuer or any Project Company to any other Project
Company is hereby subordinated to all of the Guaranteed Obligations on the same
terms as required in respect of subordinated Debt of the Issuer and the Project
Companies pursuant to this Agreement as set forth in Exhibit H to this
Agreement.

         6.8 Subrogation. So long as the Financing Documents remain in effect
and until all of the Guaranteed Obligations have been paid in full, (a) no
Project Company shall have any right of subrogation and each Project Company
waives all rights to enforce any remedy which the Secured Parties now have or
may hereafter have against the Issuer or any other Project Company, and waives
the benefit of, and all rights to participate in, any security now or hereafter
held by the Collateral Agent or any other Secured Party from the Issuer or any
of the Project Companies, and (b) each Project Company waives any claim, right
or remedy which it may now have or hereafter acquire against the Issuer or any
other Project Company that arises hereunder and/or from the performance by it
hereunder, including any claim, remedy or right of subrogation, reimbursement,
exoneration, contribution, indemnification, or participation in any claim, right
or remedy of the Secured Parties against the Issuer or any Project Company, or
any security which the Secured Parties now have or hereafter acquire, whether or
not such claim, right or remedy arises in equity, under contract, by statute,
under common law or otherwise. Any amount paid to any Project Company on account
of any such subrogation rights prior to the indefeasible payment in full in cash
of the Obligations (including the Guaranteed Obligations) and the termination of
all other obligations of the Secured Parties under the Financing Documents shall
be held in trust for the benefit of the Collateral Agent and shall immediately
thereafter be paid to the Collateral Agent for the benefit of the Secured
Parties.

         6.9 Bankruptcy.

         (a) So long as the Financing Documents remain in effect and until all
of the Obligations have been paid in full, none of the Project Companies shall,
without the prior written approval of the Controlling Party, commence, or join
with any other Person in commencing, any bankruptcy, reorganization, or
insolvency proceeding against the Issuer or any other Project Company. The
obligations of each Project Company under its Guaranty shall not be altered,
limited or affected by any proceeding, voluntary or involuntary, involving the
bankruptcy, reorganization, insolvency, receivership, liquidation or arrangement
of the Issuer, NRG Energy or any Project Company, or by any defense which the
Issuer or any other Project Company may have by reason of any order, decree or
decision of any court or the administrative body resulting from any such
proceeding.

         (b) So long as the Financing Documents remain in effect and until all
of the Guaranteed Obligations have been paid in full, to the extent of any
Guaranteed Obligation, each Project Company shall file, in any bankruptcy or
other proceeding in which the filing of claims is required or permitted by Legal
Requirements, all claims which such Project Company may have against the Issuer
or any other Project Company related to any indebtedness of the Issuer or any




                                       28
<PAGE>

Project Company to such Project Company, and hereby assigns to the Collateral
Agent, on behalf of the Secured Parties, all rights of such Guarantor
thereunder. If any Project Company fails to file any such claim, the Collateral
Agent, as attorney-in-fact for such Project Company, is hereby authorized to do
so in the name of such Project Company or, in the Collateral Agent's discretion,
to assign the claim to a nominee and to cause proofs of claim to be filed in the
name of the Collateral Agent's nominee. The foregoing power of attorney is
coupled with an interest and cannot be revoked. The Collateral Agent or its
nominee shall have the sole right to accept or reject any plan proposed in any
such proceeding and to take any other action which a party filing a claim is
entitled to take. In all such cases, whether in administration, bankruptcy or
otherwise, the person authorized to pay such a claim shall pay the same to the
Collateral Agent to the extent of any Guaranteed Obligation which then remain
unpaid, and, to the full extent necessary for that purpose, each Project Company
hereby assigns to the Collateral Agent all of such Project Company's rights to
all such payments or distributions to which such Project Company would otherwise
be entitled; provided, however, that such Project Company's obligations
hereunder shall not be satisfied except to the extent that the Collateral Agent
receives cash by reason of any such payment or distribution. If the Collateral
Agent receives anything hereunder other than cash, the same shall be held as
collateral for amounts due under this Guaranty.

         6.10 Interest; Collection Expenses. Any amount required to be paid by
any Project Company pursuant to the terms of its Guaranty shall bear interest at
the Late Payment Rate or the maximum rate permitted by Legal Requirements,
whichever is less, from the date due until paid in full. If the Collateral Agent
or any other Secured Party is required to pursue any remedy against any Project
Company, such Project Company shall pay to the Collateral Agent or such Secured
Party, as the case may be, upon demand, all reasonable attorneys' fees and
expenses all other costs and expenses incurred by the Collateral Agent or such
Secured Party in enforcing its Guaranty.

         6.11 Reinstatement of Guaranty. Each Project Company's Guaranty and its
obligations of the Guarantors shall automatically be reinstated if and to the
extent that for any reason any payment made pursuant to its Guaranty is
rescinded or otherwise restored to it, whether as a result of any proceedings in
bankruptcy or reorganization or otherwise with respect to the Issuer or any
other Person or as a result of any settlement or compromise with any Person
(including any Project Company) in respect of such payment, and such Project
Company shall pay the Collateral Agent on demand all of its reasonable costs and
expenses (including reasonable fees of counsel) incurred by the Collateral Agent
in connection with such rescission or restoration.

         6.12 Termination of Guaranty. The Guaranty of a Project Company shall
terminate in its entirety upon the occurrence of a Project Release Event with
respect to such Project Company.

         6.13 Survival. The provisions of this Article 6 shall survive
satisfaction, discharge and/or termination of this Agreement and the other
Financing Documents.

         6.14 Contribution Obligations among Project Companies. In order to
provide for just and equitable contribution among the Project Companies, each
Project Company agrees that if any payment or distribution is made by a Project
Company (a "Funding Project Company")




                                       29
<PAGE>

under its Guaranty, such Funding Project Company shall be entitled to a
contribution from the other Project Companies for all such payments or
distributions, or damages and expenses incurred by such Funding Project Company
in discharging any Guaranteed Obligations. Each Project Company which is not a
Funding Project Company (a "Non-Funding Project Company") shall be liable to a
Funding Project Company with respect to any such payments or distributions, or
damages and expenses, in an aggregate amount equal to (a) the ratio of (i) the
net worth of such Non-Funding Project Company, as determined in accordance with
the most recent balance sheet of such Non-Funding Project Company at the time of
such payment by a Funding Project Company, to (ii) the aggregate net worth of
all Project Companies, similarly determined, multiplied by (b) the amount which
the Funding Project Company paid on account of the Guaranteed Obligations. If at
any time there exists more than one Funding Project Company, then payment from
the other Non-Funding Project Companies pursuant to this Section 6.14 shall be
in an aggregate amount equal in proportion to the total amount of money paid for
or on account of the Guaranteed Obligations by the Funding Project Companies
pursuant to their Guaranties. If the Funding Project Company is required to make
any payment hereunder, such Funding Project Company shall also be entitled to a
right of subrogation in respect of such payment from the other Project
Companies. Notwithstanding anything in this Section 6.14 to the contrary, the
agreements in this Section 6.14 are to establish the relative rights of
contribution of the Project Companies and shall not modify the joint and several
nature of the obligations of each Project Company owed to or for the benefit of
the Secured Parties or impair the rights of the Collateral Agent for the benefit
of the Secured Parties to hold any of the Project Companies liable for payment
of the full amount of all Guaranteed Obligations.

                           EVENTS OF DEFAULT; REMEDIES

         7.1 Issuer Events of Default. The occurrence of any of the following
events shall constitute an "Issuer Events of Default" hereunder:

                  (a) Failure to Make Payments. The Issuer shall fail to pay, in
accordance with the terms of the Financing Documents, (i) any principal of any

or any scheduled fee, cost, charge or sum due hereunder or under the other
Financing Documents within 3 Business Days after the date that such sum is due,
or (v) any other fee, cost, charge or other sum due hereunder or under the other
Financing Documents within 10 Business Days after the date that such sum is due;
provided that any such failure of the Issuer to pay the amounts described in
this Section 7.1(a) shall not be an Issuer Event of Default if such amounts are
paid (i) by one or more of the Project Companies pursuant to, and in accordance
with, their respective Guaranties, (ii) by NRG Energy (or any other Equity
Party) pursuant to, and in accordance with, the Contingent Guaranty Agreement
(or other Equity Document), or (iii) otherwise with Account Funds from the Debt
Payment Account in accordance with the terms of the Depositary Agreement.

                  (b) Judgments. One or more final judgments for the payment of
money (if such payments are not fully covered by insurance) in excess of
$5,000,000 in the aggregate shall be rendered against the Issuer, and the Issuer
shall not discharge the same or provide for its discharge in accordance with its
terms, or procure a stay of execution thereof, within 60 days after the date of
entry thereof; provided, however, that any such judgment shall not be (and shall
not constitute part of) an Issuer Event of Default under this Section 7.1(b) if
and for so long as (i) the amount of such judgment is fully covered by a valid
and binding policy of insurance between the defendant and the insurer covering
payment thereof and (ii) such insurer has been notified of, and has not disputed
the claim made for payment of, the amount of such judgment.

                  (c) Misstatements; Omissions. Any representation or warranty
by the Issuer set forth in any Financing Document or in any document entered
into in connection therewith in favor of or for the benefit of any Secured Party
or in any certificate, financial statement or other document delivered in
connection therewith for the benefit of any Secured Party shall prove to have
been incorrect in any material respect when made (or deemed made) and the facts
or events underlying such incorrect representation or warranty shall not be
changed so as to correct such representation or warranty in all material
respects for a period of 30 days (or so long as the facts or events underlying
such incorrect representation or warranty are capable of being changed so as to
correct such incorrect representation or warranty in all material respects and
the Issuer is diligently proceeding to change such events or facts, such longer
period but in no event for an aggregate period in excess of 90 days) after a
Responsible Officer of the Issuer becomes aware thereof or the Issuer first
received a notice from or on behalf of the Controlling Party (or XLCA if the
proviso to this Section 7.1(c) applies) specifying such material inaccuracy and
requiring that the facts or events underlying such incorrect representation or
warranty be changed so as to correct such incorrect representation or warranty
in all material respects; provided, however, that any Issuer Event of Default
pursuant to this Section 7.1(c) arising solely from any representation or
warranty made by the Issuer for the benefit of XLCA under the Insurance and
Reimbursement Agreement shall be an Issuer Event of Default in respect of which
no Person other than XLCA shall have the rights given to the parties to this
Agreement in respect of Issuer Events of Default generally.

                  (d) Bankruptcy; Insolvency. The Issuer shall become subject to
a Bankruptcy Event.

                  (e) Debt Cross Default. The Issuer shall default for a period
beyond any applicable grace period (i) in the payment of any principal, interest
or other amount due on any Debt for Borrowed Money of the Issuer (other than the
Obligations) and such defaulted amount, together with any other principal,

Issuer (other than the Obligations) equals or exceeds $5,000,000 in the
aggregate, or (ii) in the payment of any amount then due or performance of any
obligation then required under any agreement evidencing Debt of the Issuer
(other than the Financing Documents) if, because of such default, the holder of
such Debt accelerates the payment thereof and such accelerated amount, together
with the amount of any other Debt of the Issuer then so accelerated (other than
the Obligations), equals or exceeds $5,000,000 in the aggregate.

                  (f) ERISA. With respect to any ERISA Plan which a member of
the Controlled Group sponsors, maintains, administers, contributes to,
participates in, or has any




                                       31
<PAGE>

obligation to contribute to or any liability under, an event has occurred or a
condition exists which, together with all other such events or conditions, would
reasonably be expected to have an Issuer Material Adverse Effect.

                  (g) Breach of Terms of Financing Documents.

                  (i) The Issuer shall fail to perform or observe any of the
         covenants or other agreements set forth in Sections 2.1 (Use of
         Proceeds and Revenues), 2.6(a)(i) and (c) (Existence, Conduct of
         Business, etc.), or Article 4 (other than Section 4.6 (Investments),
         4.8 (ERISA), 4.10 (Accounts) and 4.11 (Name and Location; Fiscal
         Year)).

                  (ii) The Issuer shall fail to perform or observe any of the
         covenants or other agreements set forth in the Financing Documents
         which are not otherwise specifically provided for in Section 7.1(g)(i)
         or elsewhere in this Section 7.1 and such failure shall continue
         unremedied for a period of 30 days after the Issuer becomes aware
         thereof or receives written notice thereof from the Controlling Party;
         provided, however, if (A) such failure does not consist of a failure to
         pay money and cannot be cured within such 30 day period, (B) such
         failure is susceptible of cure within 90 days, (C) the Issuer is
         proceeding with diligence and in good faith to cure such failure, (D)
         the existence of such failure has not had and, after considering the
         nature of the cure, could not reasonably be expected to have an Issuer
         Material Adverse Effect, and (E) the Controlling Party and the
         Collateral Agent shall have received an officer's certificate signed by
         a Responsible Officer of the Issuer to the effect of clauses (A), (B),
         (C) and (D) above and stating what action the Issuer is taking to cure
         such failure, then such 30 day cure period shall be extended to such
         date, not to exceed a total of 90 days, as shall be necessary for the
         Issuer diligently to cure such failure.

                  (h) Loss of Exemption. The Issuer shall become subject to, or
not exempt from, regulation under the FPA or PUHCA, other than Section 9(a)(2)
of PUHCA, and such regulation, or loss of exemption from regulation, shall have
an Issuer Material Adverse Effect; provided that the Issuer shall have 60 days
after a Responsible Officer of the Issuer obtains knowledge of such event to
cure such event before it becomes an Issuer Event of Default so long as the
extension of time to cure such event could not reasonably be expected to have an
Issuer Material Adverse Effect.

                  (i) Issuer Collateral. (i) The grant of the Lien of any of the
Issuer Collateral Documents shall fail in any material respect to provide a
perfected Lien in favor of the Collateral Agent for the benefit of the Secured
Parties on any of the Issuer Collateral with the priority purported to be
created thereby, and the Issuer shall fail to cure any such failure within 15
days after the Issuer becomes aware thereof or receives written notice thereof
from the Collateral Agent, or (ii) the Collateral Agent shall receive a
Secretary of State report indicating that the Collateral Agent's security
interest in any of the Issuer Collateral is not prior to all other security
interests or other interests reflected in such report, other than Issuer
Permitted Liens, and the Issuer shall fail to cure such condition within 15 days
after the Issuer becomes aware thereof or receives written notice thereof from
the Collateral Agent.

         continuing and (A) has resulted in an Issuer Material Adverse Effect,
         or (B) could reasonably be expected to result in an Issuer Material
         Adverse Effect, provided that there shall be no Issuer Event of Default
         under this Section 7.1(k)(ii) if the Issuer consummates a Permitted
         Peaker Buyout (Peaker Sale/Project Event of Default) or Peaker
         Collateralization in respect of the applicable Project Company and/or
         its Project.

                  (l) Unenforceability of Financing Documents. At any time after
the execution and delivery thereof, any material provision of any Financing
Document shall cease to be in full force and effect (other than by reason of a
release of Collateral thereunder in accordance with the terms hereof or thereof,

         writing any of its obligations thereunder.

                  (ii) Any Equity Party shall fail to make any payment as and
         when due under any Equity Document to which it is a party.

                  (iii) There shall have occurred and be continuing an NRG Event
         of Default (other than pursuant to the matters referred to in Section
         7.1 (m)(i) or Section 7.1(m)(ii)), provided that there shall be no
         Issuer Event of Default pursuant to this Section 7.1(m)(iii) if the
         Equity Party shall have deposited, or caused the deposit of, cash in
         the Cash Collateral Accounts in accordance with Section 2.2(c) or

<PAGE>

                  (i) a failure of the Bayou Cove Project to reach Completion on

         of the Bayou Cove Project and the Bayou Cove Project Company; and

                  (ii) a failure of the Rockford II Project to reach Completion
         on or prior to June 30, 2003 shall not be an Issuer Event of Default

         Buyout (Completion / Loss Event) or Peaker Collateralization in respect
         of the Rockford II Project and the Rockford II Project Company.

         be, such certificate as required by Section 4.7.2(a)(ii) of the
         Depositary Agreement, provided that there shall be no Issuer Event of

                                       34
<PAGE>

         shall not be (and shall not constitute part of) a Project Event of
         Default under this Section 7.2(b) if and for so long as (i) the amount
         of such judgment is fully covered by a valid and binding policy of
         insurance between the defendant and the insurer covering payment
         thereof and (i) such insurer has been notified of, and has not disputed
         the claim made for payment of, the amount of such judgment.

                  (c) Misstatements; Omissions. Any representation or warranty
by such Project Company set forth in any Financing Document or in any document

prove to have been incorrect in any material respect when made (or deemed made)
and the facts or events underlying such incorrect representation or warranty
shall not be changed so as to correct such representation or warranty in all
material respects for a period of 30 days (or so long as the facts or events
underlying such incorrect representation or warranty are capable of being
changed so as to correct such incorrect representation or warranty in all
material respects and such Project Company is diligently proceeding to change
such events or facts, such longer period but in no event for an aggregate period
in excess of 90 days) after a Responsible Officer of such Project Company
becomes aware thereof or receives written notice thereof from or on behalf of
the Controlling Party (or XLCA if the proviso to this Section 7.2(c) applies)
specifying such material inaccuracy and requiring that the facts or events
underlying such incorrect representation or warranty be changed so as to correct
such incorrect representation or warranty in all material respects; provided,
however, that any Project Event of Default pursuant to this Section 7.2(c)
arising solely from any representation or warranty made by a Project Company for
the benefit of XLCA under the Insurance and Reimbursement Agreement shall be an
Issuer Event of Default in respect of which no Person other than XLCA shall have
the rights given to parties to this Agreement in respect of Issuer Events of
Default generally.

                  (d) Bankruptcy.

         Event.

                  (ii) Any Major Project Participant (other than such Project

         Project Participant has any remaining obligations (other than
         indemnification obligations) under the Major Project Documents related
         to such Project to which it is a party) shall become subject to a
         Bankruptcy Event; provided that no Project Event of Default shall occur
         as a result of such Bankruptcy Event if: (A) with respect to any such
         Major Project Participant that is the only Person able to provide the
         services that are being provided under the Major Project Document to
         which it is a party on a commercially reasonable basis, (x) such Major
         Project Participant is continuing to perform all of its obligations
         under such Major Project Document in accordance with the terms thereof
         and (y) the Controlling Party does not, within 60 days after the
         occurrence of such Bankruptcy Event, declare a Project Event of Default
         with respect thereto; and (B) with respect to any Major Project
         Participant in such Project Company's Project, (t) within 30 days after
         the occurrence of such Bankruptcy Event, such Project Company notifies
         the Controlling Party and the Collateral Agent in writing that it
         intends to replace the affected Person in accordance with this clause
         (B), (u) within 135 days after the occurrence of such Bankruptcy Event,
         such Project Company replaces




                                       35
<PAGE>

         the affected Person with a Person that is reasonably satisfactory to
         XLCA (if XLCA is then the Controlling Party) or whose replacement of
         the affected Person could not reasonably be expected to have a Project
         Material Adverse Effect (if XLCA is not then the Controlling Party)
         pursuant to documentation that is reasonably satisfactory to XLCA (if
         XLCA is then the Controlling Party) or that could not reasonably be
         expected to have a Project Material Adverse Effect (if XLCA is not then
         the Controlling Party), and (v) such Bankruptcy Event does not have a
         Project Material Adverse Effect.

                  (e) Debt Cross Default. Such Project Company shall default for
a period beyond any applicable grace period (i) in the payment of any principal,
interest or other amount due on any Debt for Borrowed Money of such Project
Company (other than the Obligations) and such defaulted amount, together with
any other principal, interest or other amount due and unpaid on any Debt for
Borrowed Money of such Project Company (other than the Obligations) equals or
exceeds $5,000,000 in the aggregate, or (ii) in the payment of any amount then
due or performance of any obligation then required under any agreement

and such accelerated amount, together with the amount of any other Debt of such
Project Company then so accelerated (other than the Obligations), equals or
exceeds $5,000,000 in the aggregate.

         Event of Default unless such Project Company does not cure such failure
         within three Business Days after the occurrence of such failure.

                  (ii) Such Project Company shall fail to perform or observe any
         of the covenants or other agreements set forth hereunder or in any

         failure shall not be susceptible of cure or, if susceptible of cure,
         shall continue unremedied for a period of 30 days after such Project
         Company becomes aware thereof or receives written notice thereof from,
         or on behalf of, the Controlling Party; provided, however, if (A) such
         failure does not consist of a failure to pay money and cannot be cured
         within such 30-day period, (B) such failure is susceptible of cure
         within 90 days, (C) such Project Company is proceeding with diligence
         and in good faith to cure such failure, (D) the existence of such
         failure has not had and, after considering the nature of the cure,
         could not be reasonably expected to have, a Project Material Adverse
         Effect, and (E) the Controlling Party and the Collateral Agent shall
         have received an officer's certificate signed by a Responsible Officer
         of such Project Company to the effect of clauses (A), (B), (C) and (D)
         above and stating what action such Project Company is taking to cure
         such failure, then such 30-day cure period shall be extended to





                                       36
<PAGE>

         such date, not to exceed a total of 90 days, as shall be necessary for
         such Project Company diligently to cure such failure.

                  (g) Major Project Documents.

                  (i) Any Person (other than a Secured Party) shall be in breach
         of, or in default under, (A) a Major Project Document relating to such
         Project Company's Project (after giving effect to any applicable grace
         period set forth in such Major Project Document), or (B) any Consent
         related to such Major Project Document, and in each case such breach or
         default could reasonably be expected to have a Project Material Adverse
         Effect, and such breach or default shall not be susceptible of cure or,
         if susceptible of cure, shall continue unremedied for a period of 45
         days; provided that if (A) such breach or default does not consist of a
         failure to pay money and cannot be cured within such 45-day period, (B)
         such breach or default is susceptible of cure within 90 days, (C) the
         breaching party is proceeding with diligence and in good faith to cure
         such breach, and (D) the existence of such breach or default does not
         have a Project Material Adverse Effect and the extension of time to
         cure such breach or default could not, after considering the nature of
         the cure, be reasonably expected to have a Project Material Adverse
         Effect, then such 45-day cure period shall be extended to such date,
         not to exceed a total of 90 days, as shall be necessary for the
         breaching party diligently to cure such breach or default; provided,
         further, that no Project Event of Default shall be declared or deemed
         to exist as a result of any such breach or default if: (y) within the

         45-day cure period, if no extension is given), such Project Company
         replaces the affected Person (other than such Project Company) with a
         Person that is reasonably satisfactory to XLCA (if XLCA is then the
         Controlling Party) or whose replacement of the affected Person could
         not reasonably be expected to have a Project Material Adverse Effect
         (if XLCA is not then the Controlling Party) pursuant to documentation
         that is reasonably satisfactory to XLCA (if XLCA is then the
         Controlling Party) or that could not reasonably be expected to have a
         Project Material Adverse Effect (if XLCA is not then the Controlling
         Party), and (z) the existence of such breach or default does not have a
         Project Material Adverse Effect and the extension of time (if any) to
         obtain a replacement Person could not reasonably be expected to have a
         Project Material Adverse Effect.

                  (ii) Any Major Project Document relating to such Project
         Company's Project shall terminate, any material provision in any such
         Major Project Document shall for any reason cease to be valid and
         binding on any Person party thereto except upon fulfillment of such
         Person's obligations thereunder (or any such Person shall so state in
         writing), or shall be declared null and void, or the validity or
         enforceability thereof shall be contested by any party thereto or any
         Governmental Authority, or any such Person shall deny in writing that
         it has any liability or obligation thereunder, except upon fulfillment
         of its obligations thereunder, and in each case such occurrence could
         reasonably be expected to have a Project Material Adverse Effect;
         provided that no Project Event of Default shall be declared or deemed
         to exist as a result of the occurrence of such event if: (A) within 30
         days after the occurrence of such event, such Project Company notifies
         the Controlling Party and the Collateral Agent in writing that it
         intends to cure such event, (B) within 135 days after the occurrence of
         such event, such Project Company (x) replaces the affected

<PAGE>

                  Person (other than Project Company) with a Person that is
reasonably satisfactory to XLCA (if XLCA is then the Controlling Party) or whose
replacement of the affected Person could not reasonably be expected to have a
Project Material Adverse Effect (if XLCA is not then the Controlling Party)
pursuant to documentation that is reasonably satisfactory to XLCA (if XLCA is
then the Controlling Party) or that could not reasonably be expected to have a
Project Material Adverse Effect (if XLCA is not then the Controlling Party) or
(y) replaces the affected Major Project Document with a Project Document that is
reasonably satisfactory to XLCA (if XLCA is then the Controlling Party) or that
could not reasonably be expected to have a Project Material Adverse Effect (if
XLCA is not then the Controlling Party); and (C) the occurrence of such event
does not have a Project Material Adverse Effect and the extension of time to
cure such event could not reasonably be expected to have a Project Material
Adverse Effect.

from PUHCA), and such cessation or failure shall have a Project Material Adverse
Effect; provided that such Project Company shall have 60 days after a
Responsible Officer of such Project Company obtains knowledge of such cessation
or failure to cure such cessation or failure before it becomes a Project Event
of Default so long as the extension of time to cure such cessation or failure
could not reasonably be expected to have a Project Material Adverse Effect.

                  (i) Abandonment. At any time following the Completion Date for
its Project, such Project Company shall announce that it is abandoning such
Project or such Project shall be abandoned or operation thereof shall
substantially cease for a continuous period of more than 2 years for any reason.

                  (j) Permits. Any Permit shall be revoked, canceled, not
renewed or materially modified by the issuing agency or other Governmental
Authority having jurisdiction (excluding any revocation, cancellation,
non-renewal, or material modification at the request of the relevant Project
Company and with the prior written consent of the Controlling Party and the
Collateral Agent) and within 90 days thereafter the relevant Project Company is
not able to demonstrate to the reasonable satisfaction of XLCA (if XLCA is then

                  (k) ERISA. With respect to any ERISA Plan which a member of
the Controlled Group sponsors, maintains, administers, contributes to,
participates in, or has any obligation to contribute to or any liability under,

Adverse Effect.

such Project Company's Project Company Collateral Documents shall fail in any
material respect to provide a




                                       38
<PAGE>

perfected Lien in favor of the Collateral Agent for the benefit of the Secured

Collateral, or (ii) Project Company Permitted Liens as described in paragraphs
(b) and (d) of the definition of Project Company Permitted Liens) and such Lien
shall not be discharged within 15 days after such Project Company becomes aware
thereof or receives written notice thereof from the Collateral Agent.

                  (n) Interconnection Solution. The Interconnection Solution

                  (a) Each party to this Agreement agrees that the Controlling
         Party shall, subject to Section 9.2 (b) as to matters referred to in
         the proviso to Section 9.2(b), have the exclusive power to determine,
         control and direct any request, demand, authorization, direction,
         notice, consent, waiver or other action to be given, made or taken by
         any party to any Financing Document. Notwithstanding anything to the
         contrary in any Financing Document, each of the Swap Counterparty, the
         Collateral Agent and the Trustee (on behalf of itself and the
         Bondholders) agrees not to give, make or take any such request, demand,
         authorization, direction, notice, consent, waiver or other action for
         so long as XLCA is the Controlling Party (unless, in each such case, it
         is directed to do so by XLCA). Without prejudice to Section 2.11 of
         this Agreement, this Section 7.4(a) shall not prohibit (a) notices by
         the Issuer to the Swap



                                       40
<PAGE>
Counterparty under the Swap Agreement from becoming effective if, pursuant to
the express terms of the Swap Agreement, such notices are to be effective
without XLCA's consent upon being given to XLCA, or (b) the Swap Counterparty
from designating an early termination of the Swap Agreement (as expressly
permitted by its terms) without XLCA's consent.

                  (b) Each party to this Agreement agrees that the Controlling
Party shall have the exclusive power to determine the exercise of all rights and
remedies in respect of any Issuer Event of Default or any other default or event
of default under any Financing Document howsoever arising. Notwithstanding
anything to the contrary in any Financing Document, each of the Swap
Counterparty, the Collateral Agent and the Trustee (on behalf itself and the
Bondholders) agrees not to exercise any rights or remedies granted in, or
pursuant to or in respect of any, Financing Document or available to it at law
or in equity in respect of any default or event of default under any Financing
Document for so long as XLCA is the Controlling Party (unless, in each such
case, it is directed to exercise such rights and remedies by XLCA). Without
prejudice to Section 2.11 of this Agreement, this Section 7.4(b) shall not
prohibit the Swap Counterparty from designating an early termination of the Swap
Agreement (as expressly permitted by its terms) without XLCA's consent.

                  (c) Without prejudice to the generality of Section 7.4(a) or
7.4(b) of this Agreement, each of the Trustee, on behalf of itself and the
Bondholders, and the Swap Counterparty, hereby assigns to XLCA the respective
rights of the Trustee, the Bondholders and the Swap Counterparty with respect to
the Obligations to the extent of any payments under the Policy or the Swap
Policy. The foregoing assignment is in addition to, and not in limitation of,
rights of subrogation otherwise available to XLCA in respect of the Policies
(including pursuant to Section 4.2 of the Insurance and Reimbursement
Agreement), which subrogation rights are acknowledged, and agreed to, by the
other Secured Parties. Payments to XLCA in respect of the foregoing assignment
shall in all cases be subject to and subordinate to the rights of the
Bondholders to receive all scheduled payments of interest and principal under
the Bond Obligations. The Controlling Party is hereby appointed agent and
attorney-in-fact for each other Secured Party in any legal proceeding in respect
of the Obligations. Each Secured Party agrees that the Controlling Party may at
any time during the continuation of any proceeding by or against any debtor with
respect to which a claim seeking the avoidance as a preferential transfer of any
payment made with respect to the Obligations (a "Preference Claim"), or other
claim with respect to the Obligations is asserted under any proceeding in
connection with a Bankruptcy Event, direct all matters relating to such
proceeding, including, without limitation, (i) all matters relating to any
Preference Claim, (ii) the direction of any appeal of any order relating to any
Preference Claim and (iii) the posting of any surety or performance bond pending
any such appeal. The Trustee, on behalf of itself and the Bondholders, and the
Swap Counterparty each hereby agrees that XLCA shall be subrogated to, and the
Trustee, on behalf of itself and the Bondholders, and the Swap Counterparty each
hereby delegates and assigns, to the fullest extent permitted by law, the
respective rights of the Trustee, the Bondholders and the Swap Counterparty in
the conduct of any proceeding in connection with a Bankruptcy Event, including,
without limitation, all rights of any party to an adversary proceeding or action
with respect to any court order issued in connection with any such proceeding.

                  (d) Each party to this Agreement agrees that in respect of the
matters set forth or contemplated in Sections 7.4, 7.5, 7.6 and 7.7 and in
respect of related matters set forth or




                                       41
<PAGE>

contemplated in the Financing Documents, the Swap Counterparty shall abide by
the decisions, and follow and comply with the requests, of the Controlling Party
and shall have no voting or other related rights in respect of any such matters.

         7.5 Remedies. Upon the occurrence and during the continuation of an
Issuer Event of Default, the Controlling Party may, without any obligation to do
so and without further notice of default, presentment or demand for payment,
protest or notice of non-payment or dishonor, or other notices or demands of any
kind (all such notices and demands being waived), exercise any or all of the
following rights and remedies, in any combination or order, in addition (but
without prejudice to its rights as Controlling Party pursuant to Section 7.4) to
such other rights or remedies as the Secured Parties may have hereunder or under
the Collateral Documents or at law or in equity:

                  (a) Cure. Make disbursements to or on behalf of the Issuer to
cure any Issuer Event of Default hereunder and to cure any default or render any
performance under any Project Document as XLCA in its absolute discretion may
consider necessary or appropriate, whether to preserve and protect the
Collateral or the Secured Parties' interests therein or for any other reason,
and all sums so expended, together with interest on such total amount at the
Late Payment Rate (but in no event shall the rate exceed the maximum lawful
rate), shall be repaid by the Issuer to Collateral Agent promptly upon demand
therefor and shall be secured by the Financing Documents.

                  (b) Acceleration. Declare and make all sums of accrued and
outstanding principal, accrued but unpaid interest and accrued but unpaid
premium remaining under the Financing Documents, together with all unpaid
amounts, fees, costs and charges due hereunder or under any other Financing
Document (including in respect of any Reimbursement Obligation, Depositary
Obligation or Bond Obligation) immediately due and payable, and require the
Issuer immediately, without presentment, demand, protest or other notice of any
kind, all of which the Issuer hereby expressly waives, to pay to the Collateral
Agent an amount in immediately available funds equal to the aggregate amount of
any such outstanding accelerated obligations; provided that XLCA, so long as it
shall be the Controlling Party, shall not cause such an acceleration upon the
occurrence and during the continuation of an Issuer Event of Default pursuant to
Section 7.1(a) (Failure to Make Payments) if at such time (i) the discounted
present value of the aggregate amount of all payments made under the Policies
for which XLCA has not been reimbursed under the Insurance and Reimbursement
Agreement (or otherwise) is less than $25,000,000 (such discounted present value
being calculated by discounting the value of such aggregate amount back to the
Closing Date at a discount rate of 6.672826%), and (ii) no Issuer Event of
Default or Issuer Inchoate Default shall have occurred or be continuing (other
than pursuant to or in respect of Section 7.1(a) of this Agreement); and
provided, further, that in the event of an Issuer Event of Default occurring
under Section 7.1(d) (Bankruptcy), all such amounts, notwithstanding anything to
the contrary in this Agreement, shall become immediately due and payable without
further act of any Secured Party.

                  (c) Cash Collateral. Apply to any Obligation then due any
amounts on deposit in any Account, any funds on deposit in any Cash Collateral
Account, any drawings made under any Acceptable Letter of Credit or any proceeds
or any other monies of the Issuer on deposit with Depositary Agent or any
Secured Party in the manner provided in this Agreement or




                                       42
<PAGE>

in the Uniform Commercial Code and other relevant statutes and decisions and
interpretations thereunder with respect to cash collateral.

                  (d) Possession of Projects. Enter into possession of any
Project and perform any and all work and labor necessary to complete such
Project or to operate and maintain such Project, and all sums expended in so
doing, together with interest on such total amount at the Late Payment Rate,
shall be repaid by the Issuer to the Secured Party or Parties expending such
sums promptly upon demand and shall be secured by the Financing Documents to the
extent provided herein.

                  (e) Remedies Under Collateral Documents. Exercise any and all
rights and remedies available to the Secured Parties under any of the Collateral
Documents, including judicial or non-judicial foreclosure or public or private
sale of any of the Collateral pursuant to the Collateral Documents.

         7.6 Notice to Trustee and Project Events of Default. In exercising its
rights as Controlling Party in respect of remedies under Section 7.5 under this
Agreement, XLCA shall give the Trustee notice of XLCA's exercise of such
remedies (provided that failure by XLCA to give such notice shall in no way
limit, prejudice or affect XLCA's ability to exercise any remedies and XLCA
shall have no liability of any kind to any Person for failure to give such
notice). Without limiting anything set forth in this Article 7, upon the
occurrence of a Project Event of Default hereunder, the remedies available to
the Controlling Party and the other Secured Parties shall not include the
remedies set forth in Section 7.5 unless an Issuer Event of Default has also
occurred and is continuing.

         7.7 Application of Proceeds. If there shall have occurred an Issuer
Event of Default, all money, proceeds and other property received or held by the
Collateral Agent comprising Collateral or pursuant to the exercise by the
Collateral Agent of rights and remedies of the Secured Parties under any
Financing Document in respect of the Collateral shall be applied by the
Collateral Agent as follows (and if any Secured Party receives any such money,
proceeds or property other than as distributed by the Collateral Agent pursuant
to this Section 7.7, such Secured Party shall promptly pay or transfer the same
to the Collateral Agent for distribution in accordance with this Section 7.7):

                  first: to the payment of all and any fees, costs and expenses
owed to the Collateral Agent and the Trustee in their respective trust
capacities pursuant to any Financing Document;

                  second: to the payment of the whole amount then outstanding
(including accrued interest, principal and premium (if any)) of the Obligations
(or if the Obligations shall only have been accelerated in part, the whole
amount then outstanding of such part) and in case such proceeds are not
sufficient to pay in full the whole amount so outstanding, then to make pro-rata
payments without any preference or priority, to each Secured Party (other than
the Collateral Agent or the Trustee) in respect of the Obligations; and

                  third: after the payment in full of the Obligations, to the
