                  (a)      Notwithstanding anything else contained herein or in
any Security Document, it is the intent of the parties that: (i) this Agreement

Liens: the Senior Trust Estate and Lien securing the payment and performance of
the Priority Lien Obligations and the Junior Trust Estate and Lien securing the
payment and performance of the Parity Lien Obligations and (ii) the Liens
securing the Parity Lien Obligations are subject and subordinate to the Liens
securing the Priority Lien Obligations.

                  (b)      The parties hereto agree that, after the date hereof
and prior to the Discharge of Priority Lien Obligations, in no event shall the
Parity Debt Representatives or any Parity Lien Secured Parties have a Lien on or

first priority lien of the Priority Lien Secured Parties. Notwithstanding (i)
anything to the contrary contained in any Parity Lien Document and irrespective
of the time, order or method of attachment or perfection of the security
interests created by the Priority Lien Documents or the Parity Lien Documents,
(ii) anything contained in any filing or agreement to which the Priority Lien
Secured Parties or Parity Lien Secured Parties or any other party hereto

                                       17

Junior Trust Estate.

Proceeding has been commenced by or against any Obligor, until the Discharge of
Priority Lien Obligations, (i) the Parity Lien Secured Parties will not (A)
exercise or seek to exercise any rights or exercise any remedies with respect to
any Collateral that is subject to the Senior Trust Estate, (B) institute any
action or proceeding with respect to such rights or remedies with respect to any
Collateral, including any action of foreclosure, (C) contest, protest or object
to any foreclosure proceeding or action brought by the Priority Lien Secured
Parties or any other exercise by the Priority Lien Secured Parties of any rights
and remedies under any Priority Lien Documents relating to the Collateral that
is subject to the Senior Trust Estate, (D) object to the forbearance by the
Priority Lien Secured Parties to the bringing or pursuing of any foreclosure
proceeding or action or any other exercise of any rights or remedies relating to
the Collateral that is subject to the Senior Trust Estate, (E) take or receive
from the Obligors, directly or indirectly, in cash or other property or by set
off or in any other manner, the Collateral or any part thereof or proceeds
therefrom in satisfaction of the Parity Lien Obligations, (F) contest or seek to

Obligations, or the perfection thereof, or the validity or enforceability of
this Agreement, (G) take or permit any action prejudicial to or inconsistent
with the priority position of the Senior Trust Estate over the Junior Trust
Estate, (H) object to any adequate protection or similar relief requested and
obtained by the Priority Lien Secured Parties in any Insolvency Proceeding or
Bankruptcy Case with respect to any Obligor or (I) object to any consent or
approval by the Priority Lien Secured Parties to the use of cash or other
Collateral, or any similar relief, in any Insolvency Proceeding or Bankruptcy
Case with respect to any Obligor, and (ii) the Priority Lien Secured Parties
shall have the exclusive right to enforce rights and exercise remedies with
respect to any Collateral that is part of the Senior Trust Estate, regardless of
whether such Collateral may also be part of the Junior Trust Estate.
Notwithstanding the foregoing, the Parity Lien Secured Parties may enforce
rights, exercise remedies and take actions (A) without any condition or
restriction whatsoever, at any time after the Discharge of Priority Lien
Obligations, (B) as necessary to perfect a Lien upon any Collateral by any
method of perfection except through possession or control or (C) as necessary to
prove, preserve or protect (but not enforce) the Liens securing the Parity Lien
Obligations.

                  (d)      In exercising rights and remedies with respect to the
Collateral, the Priority Debt Representatives may enforce (or refrain from
enforcing) the provisions of the Priority Lien Documents and exercise (or
refrain from exercising) remedies thereunder or any such rights and remedies,
all in such order and in such manner as they may determine in the exercise of
their sole and exclusive discretion, including (i) the exercise or forebearance
from exercise of all rights and remedies in respect of the Collateral and/or the
Priority Lien Obligations, (ii) the enforcement or forbearance from enforcement
of any Lien in respect of the Collateral, (iii) the release, with or without
consideration, of the Collateral from the Senior Trust Estate, and, in
connection with any such release, the concurrent release, with or without
consideration (as determined by the Priority Lien Secured Parties), of such
collateral from the Junior Trust Estate, (iv) the exercise or forebearance from
exercise of rights and powers of a holder of shares of stock included in the
Senior Trust Estate to the extent provided in the

                                       18

Security Documents, (v) the acceptance of the Collateral in full or partial
satisfaction of the Priority Lien Obligations and (vi) the exercise or
forebearance from exercise of all rights and remedies of a secured lender under
the UCC or any similar law of any applicable jurisdiction or in equity.

                  (e)      Without in any way limiting the generality of the
foregoing paragraphs, the Priority Lien Secured Parties may, at any time and
from time to time, without the consent of or notice to the Parity Lien Secured
Parties, without incurring responsibility to the Parity Lien Secured Parties and
without impairing or releasing the subordination provided in this Agreement or
the obligations hereunder of the Parity Lien Secured Parties, do any one or more
of the following: (i) change the manner, place or terms of payment or extend the
time of payment of, or renew or alter, the Priority Lien Obligations, or
otherwise amend or supplement in any manner the Priority Lien Obligations, or
any instrument evidencing the Priority Lien Obligations or any agreement under

or any other legal or equitable principle or doctrine which could otherwise, in
any way, constrain, limit or affect the order or manner of the enforcement
against any person obligated for the Priority Lien Obligations or the
liquidation of the Senior Trust Estate shall not be applicable to the Senior
Trust Estate or to the rights of the Priority Lien Secured Parties under this
Agreement.

         SECTION 2.4 Collateral Shared Equally and Ratably within Class. The
parties hereto agree that the payment and satisfaction of all of the Secured
Obligations within each Class shall be secured equally and ratably by the
security interests established in favor of the Collateral Trustee for the
benefit of the Secured Parties belonging to such Class. It is understood and
agreed that nothing in this Section 2.4 is intended to alter the priorities
among Secured Parties belonging to different Classes as provided in Section 2.3
hereof.

                  SECOND, to the respective Priority Debt Representatives for

held by the Priority Debt Representatives in respect of all Priority Lien
Obligations is sufficient to pay all Priority Lien Obligations in full in cash;

                  THIRD, to the respective Parity Debt Representatives for

Priority Lien Obligations in accordance with clause (a) above and, with respect
to a Parity Debt Representative, a Responsible Officer of such Parity Debt
Representative shall have received written notice, or shall have actual
knowledge, of the same prior to such Parity Debt Representative's distribution
of such proceeds, whether after the commencement of a Bankruptcy Case or
otherwise, such Parity Debt Representative or such holder of a Parity Lien
Obligation, as the case may be, shall forthwith deliver the same to the

                                       21

<PAGE>

Collateral Trustee, for the account of the holders of the Priority Lien
Obligations, in the form received, duly indorsed to the Collateral Trustee, for

held by such Parity Debt Representative or such holder of a Parity Lien
Obligation, as the case may be, for the benefit of the holders of the Priority
Lien Obligations and shall be deemed to be held segregated from other funds and
property held by such Parity Debt Representative or such holder of a Parity Lien
Obligation.

act or omission of the Collateral Trustee.

         SECTION 3.6 Documents and Communications. The Collateral Trustee will
permit each Secured Debt Representative and each Secured Debtholder upon
reasonable written notice from time to time to inspect and copy, at the cost and
expense of the party requesting such copies, any and all Security Documents and
other documents, notices, certificates, instructions or communications received
by the Collateral Trustee in its capacity as such.

         SECTION 3.7 For Sole and Exclusive Benefit of Holders of Secured
Obligations. The Collateral Trustee shall accept, hold, administer and enforce
all Liens at any time transferred or delivered to it and all other interests,
rights, powers and remedies at any time granted to or enforceable by the
Collateral Trustee and all other property of the Trust Estates solely and
exclusively for the benefit of the present and future holders of present and
future Secured Obligations, and shall distribute all proceeds received by it in
realization thereon or from enforcement thereof solely and exclusively pursuant
to the provisions of Section 3.4.

         SECTION 3.8 Additional Secured Debt.

                  (a)      The Collateral Trustee will, as trustee hereunder,
perform its undertakings set forth in Section 3.1(a) with respect to each holder
of Secured Obligations of a Series of Secured Debt that is issued or incurred
after the date hereof that (i) holds Secured Obligations that are identified as
a holder of Parity Lien Debt or Priority Lien Debt in accordance with the
procedures set forth in Section 3.8(b) and (ii) signs, through its designated
Secured Debt Representative identified pursuant to Section 3.8(b), a Collateral
Trust Joinder.

                  (b)      The Company or other applicable Obligor shall be
permitted to designate as additional Secured Debtholders hereunder each person
who is, or who becomes, the registered holder of Parity Lien Debt or the holder
of Priority Lien Debt incurred by the Company or such other Obligor after the

                                       22

<PAGE>

Credit Agreement (including issuances of letters of credit) shall be deemed to
be incurred on the date hereof so that no such further designation shall be
required to be made so that all such extensions of credit under the Credit
Agreement (regardless when made or incurred) shall be deemed Priority Lien Debt.
The Company or other applicable Obligor may effect such designation by
delivering to the Collateral Trustee, with copies to each previously identified
Secured Debt Representative, each of the following:

                           (i)      An officer's certificate of the Company
        stating that:

                                    (A)      the Company or such other Obligor
                  intends to incur additional Secured Debt ("New Secured Debt")
                  which shall either be (x) Priority Lien Debt permitted by each
                  agreement governing Secured Debt to be secured with a Priority
                  Lien on a pari passu basis with all previously existing
                  Priority Lien Debt and which, when incurred and after giving
                  pro forma effect to the incurrence of such Priority Lien Debt
                  and the application of the proceeds therefrom, shall be in an
                  aggregate principal amount that is permitted by the terms of
                  the Secured Debt Documents or (y) Parity Lien Debt permitted
                  by each agreement governing Secured Debt to be secured with a
                  Parity Lien on a pari passu basis with all previously existing
                  Parity Lien Debt and which, when incurred and after giving pro
                  forma effect to the incurrence of such Parity Lien Debt and
                  the application of the proceeds therefrom, shall be in an
                  aggregate principal amount that is permitted by the terms of

                                    (B)      after giving pro forma effect to
                  the incurrence of such New Secured Debt and the application of
                  the proceeds therefrom, no Secured Debt Default shall have
                  occurred and be continuing and, to the best of the signatory's
                  knowledge after due inquiry, no event or condition shall have
                  occurred which could reasonably be expected to result in a
                  Secured Debt Default;

                           (ii)     evidence that the Company or such other

         is secured by the Collateral;

                           (iii)    evidence that the officer's certificate
         delivered pursuant to clause (i) above has been duly authorized by the
         Board of Directors of the Company and has been duly executed and
         delivered; and

                           (iv)     a written notice specifying the name and
         address of the Secured Debt Representative for such series of New
         Secured Debt for purposes of Section 7.5.

Notwithstanding the foregoing, nothing in this Agreement shall be construed to
allow the Company or any other Obligor to incur additional Indebtedness unless
otherwise permitted by the terms of the Secured Debt Documents.

                           (ii)     as to any Collateral that is sold,

         by all of the Secured Debt Documents at the time of such sale, transfer
         or other disposition or to the extent of the interest sold, transferred
         or otherwise disposed of; and

                           (iii)    as to any Collateral other than Collateral
         being released pursuant to clauses (i) or (ii) of this Section 4.1(a),
         if consent to the release of such Collateral has been given by an Act
         of Instructing Debtholders; provided that if such Collateral represents
         all or substantially all of the Collateral, consent to release of such
         Collateral has been given by the requisite percentage or number of
         holders of each Series of Secured Debt under the applicable Secured

                  (b)      The Collateral Trustee agrees for the benefit of the
Company and the other Obligors that if the Collateral Trustee at any time

         such officer has made such examination or investigation as is necessary
         to enable him or her to express an informed opinion as to whether or
         not the conditions precedent in this Agreement and all other Secured
         Debt Documents, if any, relating to the release of the Collateral have
         been complied with and (z) in the opinion of such officer, such
         conditions precedent, if any, have been complied with;

                           (ii)     the proposed instrument or instruments
         releasing such Lien as to such property in recordable form, if

                                       24

<PAGE>

         permitted by Section 4.1(a) and the respective Secured Debt Documents
         governing the Secured Obligations the holders of which such Secured
         Debt Representative represents,

then the Collateral Trustee will execute (with such acknowledgements and/or
notarizations as are required) and deliver such release to the Company or other
applicable Obligor on or before the later of (x) the date specified in such
request for such release and (y) the fifth Business Day after the date of

         clause (ii) of Section 4.1(a), if the terms of any such sale, transfer
         or other disposition require the payment of the purchase price to be
         contemporaneous with the delivery of the applicable release, then, at
         the request of the Company or other applicable Obligor, the Collateral
         Trustee shall either be present at the closing of such transaction or
         shall deliver the release under customary escrow arrangements that
         permit such contemporaneous payment and delivery of the release; and

                           (ii)     at any time when a Secured Debt Default

                  (d)      Each Secured Debt Representative hereby agrees that:

                           (i)      as soon as reasonably practicable after
         receipt of an officer's certificate from the Company pursuant to
         Section 4.1(b)(i) it will, to the extent required by such Section,
         either provide (x) the written confirmation required by Section
         4.1(b)(iii), (y) a written statement that such release is not permitted

         Company reasonably necessary to determine whether the proposed release
         is permitted by Section 4.1(a) and after receipt of such information
         such Secured Debt Representative will as soon as reasonably practicable
         either provide the written confirmation or statement required pursuant
         to clause (x) or (y), as applicable; and

                           (ii)     within one Business Day of the receipt by it
         of any notice from the Collateral Trustee pursuant to Section
         4.1(c)(ii), such Secured Debt Representative shall deliver a copy of
         such notice to each registered holder of the Series of Priority Lien

not be obligated to take notice thereof or to act thereon, subject to Section
4.1(d).

         SECTION 4.3 Collateral Trustee not Required to Serve, File or Record.
The Collateral Trustee is not required to serve, file, register or record any
instrument releasing or subordinating its security interest in any Collateral.

                ARTICLE 5. IMMUNITIES OF THE COLLATERAL TRUSTEE

         SECTION 5.1 No Implied Duty. The Collateral Trustee will not have any
fiduciary duties nor will it have responsibilities other than those expressly
assumed by it in this Agreement and the other Security Documents. The Collateral
Trustee shall not be required to take any action which is contrary to applicable
law or any provision of this Agreement or the other Security Documents.

         SECTION 5.2 Appointment of Agents and Advisors. The Collateral Trustee
may execute any of the trusts or powers hereunder or perform any duties
hereunder either directly or by or through agents, attorneys, accountants,
appraisers or other experts or advisors selected by it in good faith as it may
reasonably require and shall not be responsible for any misconduct or negligence
on the part of any of them.

         SECTION 5.3 Other Agreements. The Collateral Trustee has accepted and
is bound by the Security Documents executed by the Collateral Trustee as of the
date of this Agreement and, as directed by an Act of Instructing Debtholders,
the Collateral Trustee may execute additional Security Documents delivered to it
after the date of this Agreement, provided, however, that such additional
Security Documents do not adversely affect the rights, privileges, benefits and
immunities of the Collateral Trustee. The Collateral Trustee shall not otherwise
be bound by, or be held obligated by, the provisions of any credit agreement,
indenture or other agreement governing Secured Debt (other than this Agreement
and the other Security Documents).

         SECTION 5.4 Solicitation of Instructions.

                  (a)      The Collateral Trustee may at any time solicit
written confirmatory instructions, in the form of an Act of Instructing
Debtholders or an order of a court of competent jurisdiction, as to any action
which it may be requested or required to take, or which it may propose to take,
in the performance of any of its obligations under this Agreement.

                  (b)      No written direction given to the Collateral Trustee
by an Act of Instructing Debtholders, which in the sole judgment of the
Collateral Trustee imposes, purports to impose or might reasonably be expected
to impose upon the Collateral Trustee any obligation or liability not set forth
in or arising under this Agreement and the other Security Documents shall be
binding upon the Collateral Trustee unless the Collateral Trustee elects, at its
sole option, to accept such direction.

         SECTION 5.5 Limitation of Liability. The Collateral Trustee shall not
be responsible or liable for any action taken or omitted to be taken by it
hereunder or under any other Security Document, except for its own gross
negligence, bad faith or willful misconduct as determined by a court of
competent jurisdiction.

         SECTION 5.6 Documents in Satisfactory Form. The Collateral Trustee
shall be entitled to require that all agreements, certificates, opinions,
instruments and other documents at

                                       26

<PAGE>

any time submitted to it, including those expressly provided for in this
Agreement, be delivered to it in a form and with substantive provisions
reasonably satisfactory to it.

         SECTION 5.7 Entitled to Rely. The Collateral Trustee may conclusively
rely upon any certificate, notice or other document (including any facsimile)
reasonably 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 need not investigate
any fact or matter stated in any such document. The Collateral Trustee may seek
and rely upon any judicial order or judgment, upon any advice, opinion or
statement of legal counsel, independent consultants and other experts selected
by it in good faith and upon any certification, instruction, notice or other
writing delivered to it by the Company or any other Obligor in compliance with
the provisions of this Agreement or delivered to it by any Secured Debt
Representative as to the Secured Debtholders for whom it acts, without being
required to determine the authenticity thereof or the correctness of any fact
stated therein or the propriety or validity of service thereof. The Collateral
Trustee may act in reliance upon any instrument comporting with the provisions
of this Agreement or any signature reasonably believed by it to be genuine and
may assume that any person purporting to give notice or receipt or advice or
make any statement or execute any document in connection with the provisions
hereof has been duly authorized to do so. To the extent an officer's certificate
or an opinion of counsel is required or permitted under this Agreement to be
delivered to the Collateral Trustee in respect of any matter, the Collateral
Trustee may rely conclusively on such officer's certificate or opinion of
counsel as to such matter.

         SECTION 5.8 Secured Debt Default. The Collateral Trustee shall not be
required to inquire as to the occurrence or absence of any Secured Debt Default
and shall not be affected by or required to act upon any notice or knowledge as
to the occurrence of any Secured Debt Default unless and until it receives a
Notice of Actionable Default or a Responsible Officer of the Collateral Trustee
has actual knowledge that an Actionable Default has occurred and is continuing.

         SECTION 5.9 Actions by Collateral Trustee. As to any matter not
expressly provided for by this Agreement, the Collateral Trustee shall act or
refrain from acting as directed by an Act of Instructing Debtholders and shall
be fully protected if it does so.

         SECTION 5.10 Security or Indemnity in favor of the Collateral Trustee.
The Collateral Trustee shall not be required to advance or expend any funds or
otherwise incur any financial liability in the performance of its duties or the
exercise of its powers or rights hereunder unless it has been provided with
security or indemnity reasonably satisfactory to it against any and all
liability or expense which may be incurred by it by reason of taking or
continuing to take such action.

         SECTION 5.11 Rights of the Collateral Trustee. In the event there is
any bona fide, good faith disagreement between the other parties to this
Agreement or any of the other Security Documents resulting in adverse claims
being made in connection with Collateral held by the Collateral Trustee and the
terms of this Agreement or any of the other Security Documents do not
unambiguously mandate the action the Collateral Trustee is to take or not to
take in connection therewith under the circumstances then existing, or the
Collateral Trustee is in doubt as to what action it is required to take or not
to take hereunder, it shall be entitled to refrain from

                                       27

<PAGE>

taking any action (and shall incur no liability for doing so) until directed
otherwise in writing by a request signed jointly by the parties hereto entitled
to give such direction or by order of a court of competent jurisdiction.

         SECTION 5.12 Limitations on Duty of Collateral Trustee in Respect of
Collateral.

                  (a)      Beyond the exercise of reasonable care in the custody
of Collateral in its possession, the Collateral Trustee shall have no duty as to
any Collateral in its possession or control or in the possession or control of
any agent or bailee or any income thereon or as to preservation of rights
against prior parties or any other rights pertaining thereto and the Collateral
Trustee shall not be responsible for filing any financing or continuation
statements or recording any documents or instruments in any public office at any
time or times or otherwise perfecting or maintaining the perfection of any
security interest in the Collateral. The Collateral Trustee shall be deemed to
have exercised reasonable care in the custody of the Collateral in its
possession if the Collateral is accorded treatment substantially equal to that
which it accords its own property, and the Collateral Trustee shall not be
liable or responsible for any loss or diminution in the value of any of the
Collateral by reason of the act or omission of any carrier, forwarding agency or
other agent or bailee selected by the Collateral Trustee in good faith.

                  (b)      The Collateral Trustee shall not be responsible for
the existence, genuineness or value of any of the Collateral or for the
validity, perfection, priority or enforceability of the Liens in any of the
Collateral, whether impaired by operation of law or by reason of any action or
omission to act on its part hereunder, except to the extent such action or
omission constitutes gross negligence, bad faith or willful misconduct on the
part of the Collateral Trustee, for the validity or sufficiency of the
Collateral or any agreement or assignment contained therein, for the validity of
the title of any Obligor to the Collateral, for insuring the Collateral or for
the payment of taxes, charges, assessments or Liens upon the Collateral or
otherwise as to the maintenance of the Collateral. The Collateral Trustee hereby
disclaims any representation or warranty to the present and future holders of
the Secured Obligations concerning the perfection of the Liens and security
interests granted hereunder or in the value of any of the Collateral.

         SECTION 5.13 Assumption of Rights, Not Assumption of Duties.
Notwithstanding anything to the contrary contained herein, (a) each of the
parties thereto shall remain liable under each of the Security Documents (other
than this Agreement) to the extent set forth therein to perform all of their
respective duties and obligations thereunder to the same extent as if this
Agreement had not be executed, (b) the exercise by the Collateral Trustee of any
of its rights, remedies or powers hereunder shall not release such parties from
any of their respective duties or obligations under the other Security Documents
and (c) the Collateral Trustee shall not be obligated to perform any of the
obligations or duties of any of the parties thereunder other than the Collateral
Trustee.

         SECTION 5.14 No Liability for Clean Up of Hazardous Materials. In the
event that the Collateral Trustee is required to acquire title to an asset for
any reason, or take any managerial action of any kind in regard thereto, in
order to carry out any fiduciary or trust obligation for the benefit of another,
which in the Collateral Trustee's sole discretion may cause the Collateral
Trustee to be considered an "owner or operator" under the provisions of the

                                       28

<PAGE>

Comprehensive Environmental Response Cleanup and Liability Act or any similar
Environmental Laws (collectively, "CERCLA") or otherwise cause the Collateral
Trustee to incur, or be exposed to, any Environmental Liability or any liability
under CERCLA or any other federal, state or local law, the Collateral Trustee
reserves the right, instead of taking such action, either to resign as
Collateral Trustee or to arrange for the transfer of the title or control of the
asset to a court appointed receiver. The Collateral Trustee shall not be liable
to any person for any Environmental Liability or any environmental claims or
contribution actions under any federal, state or local law, rule or regulation
by reason of the Collateral Trustee's actions and conduct as authorized,
empowered and directed hereunder or relating to the discharge, Release or
threatened Release of Hazardous Materials into the environment.

          ARTICLE 6. RESIGNATION AND REMOVAL OF THE COLLATERAL TRUSTEE

         SECTION 6.1 Resignation or Removal of Collateral Trustee. Subject to
the appointment of a successor Collateral Trustee as provided in Section 6.2 and
the acceptance of such appointment by the successor Collateral Trustee, (a) the
Collateral Trustee may resign at any time by giving not less than 30 days'
notice of resignation to each Secured Debt Representative and the Company and
(b) the Collateral Trustee may be removed at any time, with or without cause, by
an Act of Instructing Debtholders.

         SECTION 6.2 Appointment of Successor Collateral Trustee. Upon any such
resignation or removal, a successor Collateral Trustee may be appointed by an
Act of Instructing Debtholders. If no successor Collateral Trustee shall have
been so appointed and shall have accepted such appointment within 30 days after
the predecessor Collateral Trustee gave notice of resignation or was removed,
the retiring Collateral Trustee may (at the expense of the Company), at its
option, appoint a successor Collateral Trustee, or petition a court of competent
jurisdiction for appointment of a successor Collateral Trustee, which shall be a
bank or trust company (a) authorized to exercise corporate trust powers, (b)
having a combined capital and surplus of at least $500,000,000 and (c)
maintaining an office in New York, New York. The Collateral Trustee shall
fulfill its obligations hereunder until a successor Collateral Trustee meeting
the requirements of this Section 6.2 has accepted its appointment as Collateral
Trustee and the provisions of Section 6.3 have been satisfied.

         SECTION 6.3 Succession. When the person so appointed as successor
Collateral Trustee accepts such appointment:

                  (a)      such person shall succeed to and become vested with
all the rights, powers, privileges and duties of the predecessor Collateral
Trustee, and the predecessor Collateral Trustee shall be discharged from its
duties and obligations hereunder, and

                  (b)      the predecessor Collateral Trustee shall promptly
transfer all Liens and collateral security and other property of the Trust
Estates within its possession or control to the possession or control of the
successor Collateral Trustee and shall execute instruments and assignments as
may be necessary or desirable or reasonably requested by the successor
Collateral Trustee to transfer to the successor Collateral Trustee all Liens,
interests, rights, powers and remedies of the predecessor Collateral Trustee in
respect of the Security Documents or the Trust Estates.

                                       29

Thereafter the predecessor Collateral Trustee shall remain entitled to enforce
the immunities granted to it in Article 5 and the provisions of Sections 7.7 and
7.8.

                      ARTICLE 7. MISCELLANEOUS PROVISIONS

         SECTION 7.1 Amendment.

                  (a)      No amendment or supplement to the provisions of this
Agreement or any other Security Document (to which the Collateral Trustee is a
party) will be effective without the approval of the Collateral Trustee acting
as directed by an Act of Instructing Debtholders, except that:

                           (i)      any amendment or supplement that has the
         effect solely of adding or maintaining Collateral, securing additional
         Secured Debt that was otherwise permitted by the terms of the Secured
         Debt Documents to be secured by the Collateral or preserving or
         perfecting the Liens thereon or the rights of the Collateral Trustee
         therein will become effective when executed and delivered by the
         Company or any other applicable Obligor party thereto and the
         Collateral Trustee;

                           (ii)     no amendment or supplement that reduces,
         impairs or adversely affects the right of any Secured Debtholder (A) to
         vote its outstanding Secured Debt as to any matter described as subject
         to an Act of Instructing Debtholders (or amends the provisions of this
         clause (ii) or the definition of "Act of Instructing Debtholders" or
         "Actionable Default"), (B) to share in the order of application
         described in Section 3.4 in the proceeds of enforcement of or

         forth in the provisions described in Section 4.1 shall become effective

         each Series of Secured Debt so affected under the applicable Secured
         Debt Document;

                           (iii)    no amendment or supplement that imposes any
         obligation upon the Collateral Trustee or any Secured Debt
         Representative or adversely affects the rights of the Collateral
         Trustee or any Secured Debt Representative, respectively, in its
         capacity as such shall become effective without the consent of the
         Collateral Trustee or such Secured Debt Representative, respectively;
         and

                           (iv)     any amendment or supplement that has the
         effect solely of adding a parallel debt hereunder in respect of any
         future Series of Secured Debt that shall become entitled to the
         benefits of this Agreement, which is in form substantially the same as
         the Credit Agreement Parallel Debt and the Indenture Parallel Debt
         contained herein, will become effective when executed and delivered by
         the Company or any other applicable Obligor party thereto, the
         applicable Secured Debt Representative with respect to such future
         Series of Secured Debt and the Collateral Trustee.

The Collateral Trustee shall not enter into any such amendment or supplement
unless it shall have received an officer's certificate of the Company to the
effect that such amendment or supplement will not result in a breach of any
provision or covenant contained in any of the

                                       30

<PAGE>

Secured Debt Documents. Prior to executing any amendment or supplement pursuant
to this Section 7.1, the Collateral Trustee shall be entitled to receive an
opinion of counsel of the Company to the effect that the execution of such
document is authorized or permitted hereunder, and with respect to amendments
adding Collateral, an opinion of counsel of the Company addressing customary
perfection, and if such additional Collateral consists of equity interests of
any person, priority, matters with respect to such additional Collateral.
Notwithstanding the foregoing, any amendment, supplement or other agreement
regarding the provisions of the Security Documents that releases Collateral will
be effective only in accordance with the requirements set forth in Section 4.1.

                  (b)      The Collateral Trustee, acting as directed by an Act
of Instructing Debtholders, and the Obligors may, at any time and from time to
time, without the consent of any Parity Lien Secured Parties, enter into
amendments or other written agreements supplemental to any Security Document
that is a Priority Lien Document for the purpose of adding to, or deleting from,
or waiving or consenting to any departures from any provisions of, any Security
Document that is a Priority Lien Document or changing in any manner the rights
of the holders of the Priority Lien Secured Parties or the Obligors thereunder.
Any amendment or waiver of, or any consent under, any provision of any Priority
Lien Document that is a Security Document (except to the extent that such
amendment, waiver or consent, would have the effect of releasing Collateral from
the Junior Trust Estate not in accordance with Section 4.1) shall apply
automatically to any comparable provision of any comparable Parity Lien Document
without the consent of or notice to any Parity Lien Secured Parties and without
any action by any Obligor or any Parity Lien Secured Parties. The Company shall
promptly notify the Parity Lien Secured Parties of any amendment or waiver of,
or any consent under, any provision of any Priority Lien Document that is a
Security Document that applies automatically to any comparable provision of any
comparable Parity Lien Document, which notice shall include a copy of such
amendment, waiver or consent, as applicable, provided that the failure to give
such notice shall not affect the validity of such amendment or waiver of, or
consent under, the Priority Lien Documents.

                  (c)      Without an Act of Instructing Debtholders, no Parity
Lien Document that is a Security Document (but that is not also a Priority Lien
Document) may be amended, supplemented or otherwise modified or entered into to
the extent such amendment, supplement or modification, or the terms of any new
Parity Lien Document that is a Security Document, would be inconsistent with any
of the terms of the Priority Lien Documents or this Agreement. The Parity Lien
Secured Parties agree that each Parity Lien Document that is a Security Document
(but that is not also a Priority Lien Document) shall include the following
language:

                  "Notwithstanding anything herein to the contrary, the lien and
security interest granted to the Collateral Trustee pursuant to this Agreement
and the exercise of any right or remedy by such Collateral Trustee hereunder are
subject to the provisions of the Collateral Trust Agreement, dated as of
December 23, 2003 (the "Collateral Trust Agreement") among Credit Suisse First
Boston, acting through its Cayman Islands Branch, as Administrative Agent, the
Collateral Trustee, Law Debenture Trust Company of New York, as Trustee, NRG
Energy, Inc. and NRG Power Marketing Inc., as the Credit Agreement Borrowers,
and the other Guarantors party thereto (as amended, modified or supplemented
from time to time). In the event of any

                                       31

<PAGE>

conflict between the terms of the Collateral Trust Agreement and this Agreement,
the terms of the Collateral Trust Agreement shall govern."

; provided, however, that if the jurisdiction in which any such Parity Lien
Document shall be filed prohibits the inclusion of the language above or would
prevent a document containing such language to be recorded of record, the Parity
Debt Representatives and the Priority Debt Representatives agree, prior to such
Parity Lien Document being entered into, to negotiate in good faith replacement
language stating that the lien and security interest granted under such Parity
Lien Document is subject to the provisions of this Agreement.

         SECTION 7.2 Further Assurances The Company and each of the other
Obligors shall do or cause to be done all acts and things which may be required,
or which the Collateral Trustee from time to time may reasonably request, to
assure and confirm that the Collateral Trustee holds, for the benefit of the
holders of the applicable Secured Obligations, duly created and enforceable and
except, with respect to any Series of Secured Debt, to the extent not required
to be perfected by the Secured Debt Documents relating to such Series of Secured
Debt, perfected Liens upon the Collateral, including after-acquired Collateral
and any property or assets which become Collateral pursuant to the definition
thereof after the date hereof, subject, in the case of Parity Lien Obligations
with respect to the Collateral that secures such Parity Lien Obligations, only
to the Priority Liens and those Liens that arise by operation of law and are not
voluntarily granted, in each case as contemplated by the Secured Debt Documents.

                  Upon the reasonable request of the Collateral Trustee at any
time and from time to time, the Company and each of the other Obligors shall
promptly execute, acknowledge and deliver such security documents, instruments,
certificates, notices and other documents, and take such other actions as shall
be reasonably required, or that the Collateral Trustee may reasonably request,
to create, perfect, protect, assure or enforce the Liens and benefits intended
to be conferred, in each case as contemplated by the Secured Debt Documents for
the benefit of the holders of Secured Obligations.

         SECTION 7.3 Successors and Assigns.

                  (a)      Except as provided in Section 5.2, the Collateral
Trustee may not, in its capacity as such, delegate any of its duties or assign
any of its rights hereunder, and any attempted delegation or assignment of any
such duties or rights shall be null and void. All obligations of the Collateral
Trustee hereunder shall inure to the sole and exclusive benefit of, and be
enforceable by, each Secured Debt Representative and each present and future
holder of Secured Obligations, each of whom shall be entitled to enforce this
Agreement as a third party beneficiary hereof, and all of their respective
successors and assigns.

                  (b)      Neither the Company nor any other Obligor may
delegate any of its duties or assign any of its rights hereunder, and any
attempted delegation or assignment of any such duties or rights shall be null
and void. All obligations of the Company and the other Obligors hereunder shall
inure to the sole and exclusive benefit of, and be enforceable by, the
Collateral Trustee, each Secured Debt Representative and each present and future
holder of Secured Obligations, each of whom shall be entitled to enforce this
Agreement as a third party beneficiary hereof, and all of their respective
successors and assigns.

         SECTION 7.4 Delay and Waiver. No failure to exercise, no course of
dealing with respect to the exercise of, and no delay in exercising, any right,
power or remedy arising under this Agreement or any of the other Security
Documents shall impair any such right, power or remedy or operate as a waiver
thereof. No single or partial exercise of any such right, power or remedy shall
preclude any other or future exercise thereof or the exercise of any other
right, power or remedy. The remedies herein are cumulative and are not exclusive
of any remedies provided by law.

                  (d)      No Obligor shall ever assert any claim against any

litigation or otherwise). In the event that all or any part of a payment or
distribution made with respect to the Priority Lien Obligations is recovered
from any of the Priority Lien Secured Parties in an Insolvency Proceeding or a
Bankruptcy Case or otherwise (and whether by demand, settlement, litigation or
otherwise), any payment or distribution received by any of the Parity Lien
Secured Parties with respect to the Parity Lien Obligations from the proceeds of
any Collateral or any title insurance policy required by any real property
mortgage at any time after the date of the payment or distribution that is so
recovered, whether pursuant to a right of subrogation or otherwise, shall be
deemed to have been received by the Parity Lien Secured Parties in trust as
property for the Priority Lien Secured Parties and the Parity Lien Secured
Parties shall forthwith deliver such payment or distribution to the Collateral
Trustee, for the benefit of the Priority Lien Secured Parties, for application
to the Priority Lien Obligations until such Priority Lien Obligations shall have
been paid in full in cash and all commitments in respect of Priority Lien
Obligations shall have been terminated.

         SECTION 7.19 Insolvency. This Agreement shall be applicable both before
and after the commencement of any Insolvency Proceeding or Bankruptcy Case by or

Administrative Agent shall be entitled to all of the rights, protections,
immunities and indemnities set forth in the Credit Agreement, the Trustee shall
be entitled to all of the rights, protections, immunities and indemnities set
forth in the Indenture and any future Secured Debt Representative shall be
entitled to all of the rights, protections, immunities and indemnities set forth
in the credit agreement, indenture or other agreement governing the applicable
Secured Debt with respect to which such person shall act as representative, in
each case as if specifically set forth herein. In no event shall any Secured
Debt Representative be liable for any act or omission on the part of the
Obligors or the Collateral Trustee hereunder.

         ARTICLE 8. CREDIT AGREEMENT PARALLEL DEBT FOR DUTCH AND SWISS
                               SECURITY INTERESTS

                  Without prejudice to the provisions of the Credit Agreement,
and for the purpose of ensuring and preserving the validity and continuity of
the security interests granted and to be granted under or pursuant to the Dutch
Security Documents and the Swiss Security Documents, the Credit Agreement
Borrowers hereby irrevocably and unconditionally undertake to pay to the
Collateral Trustee amounts equal to and in the currency of the total amount of
the Secured Obligations (as defined in the Credit Agreement), which from time to
time are due in accordance with and under the same terms and conditions as each
of the Secured Obligations (such payment undertakings and the obligations and
liabilities which are the result thereof hereinafter referred to as the "Credit
Agreement Parallel Debt").

                  The Credit Agreement Borrowers and the Collateral Trustee
acknowledge that (i) for this purpose the Credit Agreement Parallel Debt
constitutes undertakings, obligations and liabilities of the Credit Agreement
Borrowers to the Collateral Trustee which are separate and independent from, and
without prejudice to, the corresponding Secured Obligations which exist between
the Credit Agreement Borrowers and the Secured Parties (as defined in the Credit
Agreement) and (ii) the Credit Agreement Parallel Debt represents the Collateral
Trustee's own claims (vorderingen op naam) (Forderung in eigenem Namen) to
receive payment of the Credit Agreement Parallel Debt, provided that the total
amount of the Credit Agreement Parallel Debt shall never exceed the total amount
of the Secured Obligations.

                  Every payment of monies made by the Credit Agreement Borrowers
or the applicable Guarantors to the Administrative Agent (as defined in the
Credit Agreement) regarding the Credit Agreement shall, conditionally upon such
payment not subsequently being voided or reduced by virtue of any provisions or
enactments relating to bankruptcy, insolvency, liquidation or similar laws of
general application, be in satisfaction pro tanto of the covenant by the Credit
Agreement Borrowers contained in the first paragraph of this Article 8, provided
that, if any such payment as is mentioned above is subsequently voided or
reduced by virtue of any provisions or enactments relating to bankruptcy,
insolvency, liquidation or similar laws of general application, the Collateral
Trustee shall be entitled to receive a corresponding amount as Credit Agreement
Parallel Debt under the first paragraph under this Article 8 from the Credit
Agreement Borrowers and the Credit Agreement Borrowers shall remain liable to
satisfy such Credit Agreement Parallel Debt and such Credit Agreement Parallel
Debt shall be deemed not to have been discharged.

                  Subject to the provisions of the first paragraph of this
Article 8, but notwithstanding any of the other provisions of this Article 8:

                  (a)      the total amount due and payable as Credit Agreement
Parallel Debt under this Article 8 shall be decreased to the extent the Credit
Agreement Borrowers or the applicable Guarantors shall have paid any amounts to
the Secured Parties or any of them to reduce the outstanding Secured Obligations
or any of the Secured Parties otherwise receives any amount in payment of the
Secured Obligations; and

                                       38

<PAGE>

                  (b)      to the extent that the Credit Agreement Borrowers or
the applicable Guarantors shall have paid any amounts to the Collateral Trustee
under the Credit Agreement Parallel Debt or the Collateral Trustee otherwise
shall have received monies in payment of the Credit Agreement Parallel Debt, the
total amount due and payable under the Secured Obligations shall be decreased as
if said amounts were received directly in payment of the Secured Obligations.

                  For the avoidance of doubt, in the event that the Credit
Agreement Borrowers are in default in respect of the Secured Obligations, as set
forth in the Credit Agreement, the Credit Agreement Borrowers shall, at the same
time, be deemed in default in respect of their obligations under the Credit
Agreement Parallel Debt.

   ARTICLE 9. INDENTURE PARALLEL DEBT FOR DUTCH AND SWISS SECURITY INTERESTS

                  Without prejudice to the provisions of the Indenture, and for
the purpose of ensuring and preserving the validity and continuity of the
security interests granted under or pursuant to the Dutch Security Documents and
the Swiss Security Documents, the Company hereby irrevocably and unconditionally
undertakes to pay to the Collateral Trustee amounts equal to and in the currency
of the total amount of the Parity Lien Obligations in respect of the Notes,
which from time to time are due in accordance with and under the same terms and
conditions as each of the Notes and the Indenture (such payment undertakings and
the obligations and liabilities which are the result thereof hereinafter
referred to as the "Indenture Parallel Debt").

                  The Company and the Collateral Trustee acknowledge that (i)
for this purpose the Indenture Parallel Debt constitutes undertakings,
obligations and liabilities of the Company to the Collateral Trustee which are
separate and independent from, and without prejudice to, the corresponding
Parity Lien Obligations in respect of the Notes that are issued by the Company
to the holders of the Notes and (ii) that the Indenture Parallel Debt represents
the Collateral Trustee's own claims (vorderingen op naam) (Forderung in eigenem
Namen) to receive payment of the Indenture Parallel Debt, provided that the
total amount of the Indenture Parallel Debt shall never exceed the total amount
of the Parity Lien Obligations in respect of the Notes.

                  Every payment of monies made by the Company or the applicable
Guarantors to the Trustee regarding the Parity Lien Obligations in respect of
the Notes shall, conditionally upon such payment not subsequently being voided
or reduced by virtue of any provisions or enactments relating to bankruptcy,
insolvency, liquidation or similar laws of general application, be in
satisfaction pro tanto of the covenant by the Company contained in the first
paragraph of this Article 9, provided that, if any such payment as is mentioned
above is subsequently voided or reduced by virtue of any provisions or
enactments relating to bankruptcy, insolvency, liquidation or similar laws of
general application, the Collateral Trustee shall be entitled to receive a
corresponding amount as Indenture Parallel Debt under the first paragraph of
this Article 9 from the Company and the Company shall remain liable to satisfy
such Indenture Parallel Debt and such Indenture Parallel Debt shall be deemed
not to have been discharged.

                  Subject to the provision in the first paragraph in this
Article 9, but notwithstanding any of the other provisions of this Article 9:

                  (a)      the total amount due and payable as Indenture
Parallel Debt under this Article 9 shall be decreased to the extent the Company
or the applicable Guarantors shall have paid any amounts to the holders or any
of them to reduce the outstanding Parity Lien Obligations in respect of the
Notes or any of the holders otherwise receives any amount in payment of the
Parity Lien Obligations in respect of the Notes; and

                  (b)      to the extent that the Company shall have paid any
amounts to the Collateral Trustee under the Indenture Parallel Debt or the
Collateral Trustee otherwise shall have received monies in payment of the
Indenture Parallel Debt, the total amount due and payable under the Parity Lien
Obligations in respect of the Notes shall be decreased as if said amounts were
received directly in payment of the Parity Lien Obligations in respect of the
Notes.

                  For the avoidance of doubt, in the event that the Company is
in default in respect of the Parity Lien Obligations in respect of the Notes, as
set forth in the Indenture, the Company shall, at the same time, be deemed in
default in respect of its obligations under the Indenture Parallel Debt.

                  This AMENDED AND RESTATED COMMON AGREEMENT (as amended,
amended and restated, supplemented or otherwise modified from time to time, this
"Agreement"), dated as of January 6, 2004, is entered into among (1) XL Capital
Assurance Inc., a New York stock insurance company ("XLCA"), (2) Goldman Sachs
Mitsui Marine Derivative Products, L.P., a Delaware limited partnership (the
"Swap Counterparty"), (3) Law Debenture Trust Company of New York, a New York
limited purpose trust company, not in its individual capacity but solely as
successor trustee to The Bank of New York for the benefit of the holders of the
Bonds (the "Bondholders") (in such capacity, the "Trustee"), (4) The Bank of New
York, as collateral agent for the benefit of the Secured Parties (in such
capacity, the "Collateral Agent"), (5) NRG Peaker Finance Company LLC, a
Delaware limited liability company, as Issuer (the "Issuer"), and (6) each party
hereto identified as a Project Company on the signature pages hereto (each a
"Project Company" and, collectively, the "Project Companies").

                                    RECITALS

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.

                  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 issued and sold its Series A Bonds in an
         offering in reliance on Rule 144A and Regulation S under the Securities
         Act. All proceeds from the sale of the Series A Bonds were used by the
         Issuer to loan specified amounts to the Bayou Cove Project Company, the
         Rockford I Project Company and the Rockford II Project Company in
         exchange for the Project Loan Agreements such Project Companies
         executed and delivered to the Issuer.

                  D.       The Project Companies used the proceeds from their
         respective loans 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 and all additional
         amounts required to be paid to XLCA pursuant to the Policy and the
         Insurance and Reimbursement Agreement (iii) deposit $11,279,588 in a
         designated account pursuant to the original Depositary Agreement, dated
         as of the Original Closing Date, among the Issuer, each Project
         Company, the Collateral Agent and the Depository Agent (the "Original
         Depositary Agreement") and (iv) pay transaction fees and costs.

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

                  F.       The Issuer has entered into the Swap Agreement with
         the Swap Counterparty pursuant to which the Issuer will make fixed rate
         interest rate payments to

<PAGE>

         the Swap Counterparty and the Swap Counterparty will make floating rate
         interest payments to the Issuer.

                  G.       Regularly scheduled payments of principal of and
         interest on the Series A Bonds are 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.

                  H.       Regularly scheduled payments of Swap Payment Amounts
         are 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.

                  I.       Pursuant to and in accordance with the now terminated
         Contingent Guaranty Agreement, dated as of the Original Closing Date by
         NRG Energy in favor of the Collateral Agent (the "Contingent Guaranty
         Agreement"), NRG Energy was obligated to make certain payments under
         circumstances specified in the Contingent Guaranty Agreement.

                  J.       Pursuant to and in accordance with the Insurance and
         Reimbursement Agreement, the Issuer is 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.

                  K.       Pursuant to the Issuer Collateral Documents, the
         Issuer's obligations owed to the Secured Parties are 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).

                  L.       Pursuant to the Guaranties, each of the Project
         Companies guarantees unconditionally and irrevocably the obligations
         and indebtedness of the Issuer in respect of the Guaranteed
         Obligations, which Guaranties are, pursuant to the Project Company
         Collateral Documents, 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.

                  M.       As a condition precedent to the issuance of the
         Series A Bonds, the Policy and the Swap Policy and the execution of the
         Swap Agreement by the Swap Counterparty, the Parties hereto executed
         and delivered the original Common Agreement, dated as of June 18, 2002,
         among XLCA, the Swap Counterparty, the Original Trustee, the Collateral
         Agent, the Issuer and each Project Company (the "Original Common
         Agreement").

                  N.       On May 12, 2003, as a consequence of certain Issuer
         Events of Default under the Original Common Agreement, XLCA, as
         Controlling Party, declared and made all sums of accrued and
         outstanding principal, accrued

                                       2

<PAGE>

         but unpaid interest and accrued but unpaid premium remaining under the
         Financing Documents, together with all unpaid amounts, fees, costs and
         charges due under any Financing Documents, immediately due and payable
         (the "Acceleration").

                  O.       On May 14, 2003, NRG Energy and certain of its
         subsidiaries filed voluntary petitions for bankruptcy under Chapter 11
         of the United States Bankruptcy Code (the "NRG Bankruptcy").

                  P.       Following the Acceleration and the NRG Bankruptcy,
         NRG Energy, NRG Power Marketing, the Issuer, the Project Companies and
         XLCA agreed to implement a financial restructuring of the Obligations
         (the "Restructuring") substantially on the terms set forth in a
         Restructuring Agreement, dated as of September 18, 2003, by and among
         NRG Energy, NRG Power Marketing, the Issuer, the Project Companies and
         XLCA (as amended, amended and restated, supplemented or otherwise
         modified from time to time, the "Restructuring Agreement").

                  Q.       On October 1, 2003, the United States District Court
         for the Southern District of New York entered an order (the "Approval
         Order") in the NRG Bankruptcy authorizing and approving the
         transactions provided in the Restructuring Agreement including the
         execution and delivery of this Agreement by the parties hereto. The
         Approval Order became a Final Order on October 11, 2003.

                  R.       It is a condition precedent to the consummation of
         the Restructuring that the parties hereto shall have executed and
         delivered this Agreement.

                  NOW THEREFORE, in consideration of the premises contained
         herein and for other good and valuable consideration, the receipt and
         sufficiency of which are hereby acknowledged and as an inducement to
         the consummation of the Restructuring, the parties hereto agree as
         follows:

covenant until the Completion Date for such Project Company's Project. Without
prejudice to the immediately preceding sentence, each of the Bayou Cove Project
Company and the Rockford II Project Company shall, not later than 8 months after
the Completion Date for its Project, cause an as-built survey to be prepared and
delivered to XLCA (if XLCA is the Controlling Party), the Collateral Agent, the

(other than as permitted by Section 5.10), (b) its qualification to do business
in each jurisdiction in which the character of the properties owned or leased by
it or in which the transaction of its business as conducted or proposed to be

that the failure to do so could not reasonably be expected to have a Project
Material Adverse Effect and (c) its other material rights, privileges and
franchises necessary or desirable in the normal conduct of its business.

         3.7      Project Documents. Each Project Company shall exercise,
preserve and defend all of its rights under its Project Documents, except to the
extent failure to so exercise, preserve or defend such rights could not
reasonably be expected to have a Project Material Adverse Effect.

         3.8      Permits. Each Project Company shall obtain all Permits
required at any time and from time to time in connection with such Project
Company's development, construction, ownership, leasing, operation, maintenance

                  (a)      Each Project Company shall preserve the security
interests granted or purported to be granted under the Collateral Documents to

and enforce its right, title and interest in and to, and the rights of the
Collateral Agent in and to, its Project Company Collateral, including the
preparation, making or delivery of all filings and recordations, the payment of
fees and other charges and the issuance of supplemental documentation.

                  (b)      If a Project Company obtains any right, title or
interest in, to or under any real property (including leasehold interests) that
is material to the development, construction, ownership, leasing, operation,
maintenance or use of its Project and that is not covered by the Collateral
Documents to which it is a party, it shall (i) collaterally assign such right,
title or interest to the Collateral Agent for the benefit of the Secured
Parties, (ii) record a supplement to the Mortgage to which it is a party in form
and substance reasonably satisfactory to Collateral Agent encumbering such
right, title or interest by the Lien of such Mortgage, and (iii) obtain a
supplement to the applicable Title Policy insuring the first priority (subject
to Project Company Permitted Liens) of such Mortgage over such real property.

                  (c)      Each Project Company shall perform such reasonable
acts as may be necessary to carry out the intent of this Agreement (including

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
assets expressly permitted under Section 5.4 of this Agreement.

determination of the Power and Fuel Market Consultant that the Energy Marketing
Services Agreement should be terminated or (iii) a material default by NRG Power
Marketing under the Energy Marketing Services Agreement.

         executed by a Responsible Officer of the Issuer, certifying, in such
         Responsible Officer's capacity as an officer of the Issuer, to the
         effect that, to the best of such Responsible Officer's knowledge, each
         of the foregoing conditions and the other applicable conditions of this

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

         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:

                           (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

         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

<PAGE>

         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 a Disbursement Request to make distributions
to its direct equity owners from the Distribution Account (such distributions,
the "Tax Distributions") equal to the currently due and payable aggregate
Federal, state or local income tax liability of NRG Energy (or its successor for
tax purposes) in respect of items of taxable income, gain, loss, deduction and
credit arising from the operations of the Issuer and the Project Companies
(together, the "Tax Group" and such liability, the "Tax Group Liability"), which
amount for each taxing jurisdiction shall be assumed to equal the product of (i)
the net taxable income of the Tax Group for applicable Federal, state or local
income tax purposes during the relevant tax period multiplied by (ii) the
highest marginal Federal, state or local income tax rate at the time actually
applicable to the relevant taxpayer for such period in the applicable
jurisdiction with respect to such income; provided that such Tax Group Liability
(A) shall be reduced by any taxes that are actually paid by the Issuer or the
Project Companies to the relevant taxing authorities and (B) shall be calculated
by excluding the items of taxable income, gain, loss, deduction and credit
arising from the operations of any entities not included in the Tax Group (such
as any income of NRG Energy not derived from the operations of the Tax Group)
and by assuming that all of the tax attributes and benefits attributable to the
operations of the Tax Group (including, without limitation, deductions, credits,
refunds, carryovers and carrybacks) shall be applied solely with respect to the
taxable income of the members of the Tax Group; provided, however, that tax
attributes of one member of the Tax Group shall not be deemed to offset the
income of another member of the Tax Group in a taxing jurisdiction if, under
applicable law in such jurisdiction, such attributes of the first member are not
in fact permitted to offset such income of the second member; 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. In the event that
(w) any Tax Distribution exceeds (as reasonably determined by the Issuer or NRG
Energy) the amount of the actual Tax Group Liability in respect of the relevant
tax period, or (x) any entity that is not a member of the Tax Group receives a
refund of taxes from a Federal, state or local taxing authority that is
attributable (as reasonably determined by the Issuer or NRG Energy) in whole or
in part to a prior Tax Distribution, then either (y) the recipient of the
relevant Tax Distribution shall promptly return such excessive Tax Distribution
or tax refund to the Issuer or (z) future Tax Distributions that would have
otherwise been permitted under the preceding sentence of this Section 4.5(e)
shall be reduced by the amount of such excess or refund; provided that Issuer or
NRG Energy shall promptly make the determination described in (x) above and,
after making such determination, shall provide to XLCA a calculation supporting
such determination.

         (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:

                                       22

<PAGE>

                           (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
         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 (other than those disbursed from the Distribution Account)
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 (or any transaction under or pursuant to 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, in
such Responsible Officer's capacity as an 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.

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

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 (if XLCA is the Controlling Party) (at any time when there

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, the successor Person formed by
such consolidation or into which the Issuer is 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 named as the Issuer in
this Agreement and the other Financing Documents, and thereafter, except in the
case of a lease, the predecessor Person shall be relieved of all obligations and
covenants under the Financing Documents.

         4.10     Accounts. The Issuer shall not maintain, establish or use any
bank, deposit or securities accounts other than the Accounts.

         4.11     Name and Location; Fiscal Year. The Issuer shall not (a)
change its name, the location of its principal place of business, the location
of the Issuer Collateral, its jurisdiction of organization or its organizational

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

Party) (which consent shall not be

                                       24

<PAGE>

unreasonably withheld by XLCA), or in case XLCA is not the Controlling Party, if
such deviation from the Annual Operations Budget could reasonably be expected to
have an Issuer Material Adverse Effect.

         4.15     Corporate Services Agreement. The Issuer shall not (a) enter
into any agreement replacing the existing Corporate Service Agreement without
the prior written consent of XLCA, (if XLCA is the Controlling Party), which

Bayou Cove Project Company shall not be permitted to transfer the entire Site of
the Bayou Cove Project pursuant to the Bayou Cove EPC Agreement (Interconnection
Facilities)), or (e) in connection with a Permitted Peaker Buyout, provided that

Responsible Officer of such Project Company, in such Responsible Officer's
capacity as an Officer of such Project Company, the Collateral Agent shall then

provided that, in respect of each transaction or agreement 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 agreement as if such

         Project Company other than the Collateral would become subject to a
         mortgage, pledge, lien, security interest or other encumbrance that
         would not be permitted by this Agreement, such Project Company or such
         successor Person, as the case may be, shall take such steps as shall be
         necessary effectively to secure the Bonds of each series equally and
         ratably with (or prior to) all indebtedness secured thereby;

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

                                   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, the
Depositary 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 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.

                                       31

<PAGE>

         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 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;

                                       32

<PAGE>

                  (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 a Responsible Officer of 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 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

                                       33

<PAGE>

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.

         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 M 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,

                                       34

<PAGE>

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 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

                                       35

<PAGE>

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") 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 Bond Obligation on the date that such principal is due, (ii) any amount
in respect of any Reimbursement Obligation on the date that such amount is due,
(iii) any Swap Payment Amount in accordance with the Swap Agreement, (iv) any
interest on any Bond Obligation, Reimbursement Obligation, Swap Payment Amount
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 Parent 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

                                       37

<PAGE>

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, interest or other amount due and unpaid on any Debt for Borrowed
Money of the 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 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, in such Responsible Officer's
         capacity as an officer of the Issuer, to the effect of clauses (A),
         (B), (C) and (D) above and stating

                                       38

<PAGE>

         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

         7.4      Controlling Party Agreement.

                  (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 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

                                       47

<PAGE>

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 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

                                       48

<PAGE>

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 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 Collateral Agent and Project Events of
Default. In exercising its rights as Controlling Party in respect of remedies
under Section 7.5 under this Agreement, XLCA (if XLCA is the Controlling Party)
shall give the Trustee and the Collateral Agent notice of XLCA's exercise of
such remedies (provided that failure by XLCA to give such

                                       49

<PAGE>

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 and such Issuer Event of Default is continuing, 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 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 fees costs, expenses or expenditures approved
for payment in writing by the Controlling Party and (i) accrued and unpaid in
connection with the management and operation of the Project Companies or any
Collateral or (ii) subject to reimbursement under any Financing Document;

         third: to the payment of the whole amount then outstanding of all
Scheduled Debt Service and in case such proceeds are not sufficient to pay in
full the whole amount so outstanding, then to make pro rata payment without any
preference or priority, to each Secured Party (to which such Scheduled Debt
Service is payable) in respect of such Obligations;

         fourth: to the payment of such remaining 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) as the Controlling Party shall direct; and

         fifth: after the payment in full of the Obligations, the remainder, if
any, shall be paid to the Issuer or as a court of competent jurisdiction may
direct.

                                    ARTICLE 8
                               SCOPE OF LIABILITY

                  Except as set forth in this Article 8, notwithstanding
anything in this Agreement or the other Financing Documents to the contrary, the
Secured Parties shall have no claims with respect to the transactions
contemplated by the Operative Documents against NRG Energy or any of its
Affiliates (other than the Financing Parties), shareholders, officers, directors
or employees (collectively, the "Nonrecourse Persons"); provided that the
foregoing provision of this Article 8 shall not (a) constitute a waiver, release
or discharge of any of the indebtedness, or of any of the terms, covenants,
conditions, or provisions of this Agreement or any other Financing Document and
the same shall continue (but without personal liability to any

                                       50

<PAGE>

Nonrecourse Person except as provided herein and therein) until fully paid,
discharged, observed, or performed, (b) limit or restrict the right of any
Secured Party (or any assignee, beneficiary or successor to any of them) to name
the Issuer, any Project Company or any other Person as a defendant in any action
or suit for a judicial foreclosure or for the exercise of any other remedy under
or with respect to this Agreement or any other Financing Document, or for
injunction or specific performance, so long as no judgment in the nature of a
deficiency judgment shall be enforced against any Nonrecourse Person, except as
set forth in this Article 8, (c) limit or restrict any right or remedy of any
Secured Party (or any assignee or beneficiary thereof or successor thereto) with
respect to, and each of the Nonrecourse Persons shall remain fully liable to the
extent that such Person would otherwise be liable for its own actions with
respect to, any fraud (which shall not include innocent or negligent
misrepresentation), willful misrepresentation, or misappropriation of Project
Revenues or any other earnings, revenues, rents, issues, profits or proceeds
from or of the Collateral that should or would have been paid as provided herein
or paid or delivered to any Secured Party (or any assignee or beneficiary
thereof or successor thereto) towards any payment required under this Agreement
or any other Financing Document, (d) affect or diminish or constitute a waiver,
release or discharge of any specific written obligation, covenant, or agreement
made by any of the Nonrecourse Persons or any security granted by the
Nonrecourse Persons in support of the obligations of such Persons under any
Financing Document or as security for the obligations of the Issuer and the
Project Companies, and (e) limit the liability of (i) any Person who is a party
to any Project Document and has issued any certificate or other statement in
connection therewith with respect to such liability as may arise by reason of
the terms and conditions of such Project Document (but subject to any limitation
of liability in such Project Document), certificate or statement, (ii) any
Person rendering a legal opinion pursuant to this Agreement or (iii) NRG Energy
or any Acceptable Assignee under or pursuant to the Parent Agreement, in each
case under this clause (e) relating solely to such liability of such Person as
may arise under such referenced agreement, instrument or opinion. The
limitations on recourse set forth in this Article 8 shall survive the
termination of this Agreement and the full payment and performance of the
Obligations hereunder and under the other Financing Documents.

                                   ARTICLE 9
                    INDEMNIFICATION, AMENDMENTS AND WAIVERS

         9.1      Indemnification.

                  (a)      The Issuer and each Project Company shall, on an
after-tax basis, jointly and severally indemnify, defend and hold harmless XLCA
and the Collateral Agent, and in their capacities as such, their respective
officers, directors, shareholders, controlling Persons, affiliates, employees,
agents, attorneys and servants (collectively, the "Indemnitees") from and
against any and all claims, obligations, liabilities, losses, costs or expenses
(including reasonable attorneys' fees and disbursements and reasonable fees and
disbursements of consultants and auditors and reasonable costs of
investigations), penalties, actions and suits which any of them incur or which
are claimed against any of them (collectively, "General Subject Claims"), in any
way arising out of or in connection with this Agreement (including the
enforcement of this Agreement), the other Operative Documents, any of the
transactions contemplated hereby or thereby, any Project, the actual or proposed
use of proceeds of the Bonds or any refund or

                                       51

<PAGE>

adjustment of any amount paid or payable to the Collateral Agent in respect of
any Collateral or any interest thereon which may be ordered by or otherwise
required by any Person.

                  (b)      Without limiting the generality of clause (a) above,
the Issuer and each Project Company further agree to jointly and severally
indemnify, on an after-tax basis, and hold harmless each Indemnitee from and
against any and all claims, losses, liabilities, suits, obligations, fines,
damages, judgments, penalties, charges, costs and expenses (including reasonable
attorneys' fees and disbursements and reasonable fees and disbursements of
consultants and auditors and reasonable costs of investigations) (whether civil
or criminal, arising under a theory of negligence or strict liability, or
otherwise) which are imposed on, incurred or paid by or asserted against such
Indemnitee (collectively, "Environmental Subject Claims" and, together with
General Subject Claims, "Subject Claims") and (i) arising out of or resulting
from the development, construction, ownership, leasing, use, operation or
maintenance of any Site, Improvement or other Mortgaged Property, or (ii)
arising in connection with the Release or threatened Release or presence of any
Hazardous Substances in, on, under or at any Site of any Project, Improvement or
other Mortgaged Property.

                  (c)      The foregoing indemnities shall not apply with
respect to an Indemnitee to the extent that any Subject Claim is found by a
final and non-appealable decision of a court of competent jurisdiction to have
resulted from the gross negligence or willful misconduct of such Indemnitee, but
shall continue to apply to other Indemnitees.

                  (d)      The Issuer and each Project Company agree that no
Indemnitee shall have any liability (whether direct or indirect, in contract,
tort or otherwise) to the Issuer, any Project Company or any of their respective
shareholders, affiliates or creditors for or in connection with this Agreement,
the other Operative Documents or any of the transactions contemplated hereby or
thereby, except to the extent such liability is found in a final, non-appealable
court of competent jurisdiction to have resulted from such Indemnitee's gross
negligence or willful misconduct.

                  (e)      The provisions of this Section 9.1 shall survive
foreclosure of the Collateral Documents and satisfaction or discharge of the
Issuer's or each Project Company's obligations hereunder and under the other
Financing Documents, and shall be in addition to any other rights and remedies
of the Secured Parties.

                  (f)      In case any action, suit or proceeding shall be
brought against any Indemnitee, such Indemnitee shall notify the Issuer and the
Project Companies of the commencement thereof, and the Issuer and the Project
Companies shall be entitled, at their expense, acting through counsel reasonably
acceptable to such Indemnitee, to participate in, and, to the extent that the
Issuer and the Project Companies desire, to assume and control the defense
thereof; provided, however, that the Issuer or any Project Company shall not
settle or compromise any Subject Claim on behalf of such Indemnitee without such
Indemnitee's prior written consent unless such settlement or compromise includes
an unconditional release of such Indemnitee from, and holds such Indemnitee
harmless against, all liability arising out of such claim, action, proceeding or
investigation. Such Indemnitee shall be entitled, at its expense, to participate
in any action, suit or proceeding the defense of which has been assumed by the
Issuer or the Project Companies. Notwithstanding the foregoing, neither the
Issuer nor any Project

                                       52

<PAGE>

Company shall be entitled to assume and control the defense of any such action,
suit or proceedings if and to the extent that, in the 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 the Issuer or any Project Company 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) the Issuer and each
Project Company shall pay the expenses of such Indemnitee in such defense and be
jointly and severally liable for such expenses.

                  (g)      Upon payment of any Subject Claim by the Issuer or
any Project Company pursuant to this Section 9.1 or other similar indemnity
provisions contained herein to or on behalf of an Indemnitee, the Issuer or such
Project Company, 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 the Issuer and the Project Companies and give such further
assurances as are necessary or advisable to enable the Issuer and the Project
Companies vigorously to pursue such claims.

                  (h)      Notwithstanding anything to the contrary set forth
herein, the Issuer 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 9.1 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 do so, by XLCA (if XLCA is the
Controlling Party) or the Collateral Agent (if XLCA is not the Controlling
Party)), exclusive of any appropriate local counsel; provided that this Section
9.1(h) shall not apply in respect of XLCA or the Collateral Agent if it
demonstrates to the reasonable satisfaction of the Issuer that there exists a
conflict of any sort with any other Indemnitee or that XLCA or the Collateral
Agent, as the case may be, is prejudiced by such representation of XLCA or the
Collateral Agent, as the case may be, and, accordingly, Issuer shall be liable
to XLCA and the Collateral Agent under the provisions of this Section 9.1 for
the fees and expenses of XLCA's and the Collateral Agent's separate legal
counsel (and any appropriate local counsel).

                  (i)      Any amounts payable by the Issuer or any Project
Company pursuant to this Section 9.1 shall be regularly payable within 30 days
after the Issuer or any Project Company receives an invoice for such amounts
from any applicable Indemnitee, and if not paid within such 30-day period shall
bear interest at the Late Payment Rate.

                  (j)      If, for any reason whatsoever, the indemnification
provided under this Section 9.1 is unavailable to any Indemnitee or is
insufficient to hold it harmless to the extent provided in this Section 9.1,
then provided such payment is not prohibited by or contrary to any applicable
Legal Requirement or public policy, the Issuer and each Project Company 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 the Issuer and each Project Company and their respective
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 the

                                       53

<PAGE>

Issuer and each Project Company (and their respective Affiliates) and such
Indemnitee with respect to such Subject Claim, and any other relevant equitable
considerations.

forth in Section 9.2(b) below, neither this Agreement (including the Guaranties)
nor any of the terms hereof may be amended, supplemented, modified or waived,

waiver, consent, approval, agreement or other action under or with respect to,
any Financing Document; provided, however, that no such amendment, supplement,

Indenture) Bond affected thereby; and provided, further, that no such amendment
or supplement that results in the Swap Counterparty no longer being designated a
Secured Party or changes its rights to receive payments in respect of the Swap
Obligations in accordance with Section 2.11 of the Common Agreement or Section
4.1.2 of the Depository Agreement shall be made without the consent of the Swap
Counterparty; provided, however, that no such amendment, supplement,
modification, waiver, consent, approval, agreement or action that adversely
affects the rights of the Collateral Agent provided in Article 11 of the Common
Agreement in any material respect or its compensation or indemnity in any

                              THE COLLATERAL AGENT

         11.1     Appointment and Duties of Collateral Agent.

                  (a)      Appointment and Duties of Collateral Agent. Each of
XLCA, the Swap Counterparty and the Trustee hereby designates and appoints The
Bank of New York to act as the Collateral Agent for the Transaction, and XLCA,
the Swap Counterparty and the Trustee hereby authorize The Bank of New York, as
the Collateral Agent, to take such actions on its behalf under the provisions of
the Collateral Documents to which it is a party and to exercise such powers and
perform such duties as are expressly delegated to the Collateral Agent by the
terms thereof and this Agreement and each of the other Financing Documents to
which it is a party, together with such other powers as are reasonably
incidental thereto. Notwithstanding any provision to the contrary elsewhere in
this Agreement and the other Financing Documents, the Collateral Agent shall not
have any duties or responsibilities, except those expressly set forth in this
Agreement and the other Financing Documents to which it is a party, or any
fiduciary relationship with XLCA, the Swap Counterparty or the Trustee, and no
implied covenants, functions or responsibilities shall be read into this
Agreement, the other Financing Documents or otherwise exist against the
Collateral Agent. The Collateral Agent shall not be liable for any action taken
or omitted to be taken by it hereunder or under any other Financing Document, or
in connection herewith or therewith, or in connection with the Collateral,
unless caused by its gross negligence or willful misconduct as determined by a
court of competent jurisdiction.

                  Anything in this Agreement to the contrary notwithstanding, in
no event shall the Collateral Agent or the Trustee be liable under or in
connection with this Agreement for indirect, special, incidental, punitive or
consequential losses or damages of any kind whatsoever, including but not
limited to lost profits, whether or not foreseeable, even if the Collateral
Agent or the Trustee (in any of its capacities hereunder) has been advised of
the possibility thereof and regardless of the form of action in which such
damages are sought.

                                       56

<PAGE>

                  (b)      Notices to XLCA, the Swap Counterparty, the Trustee
and the Issuer. The Collateral Agent will give notice to XLCA, the Swap
Counterparty, the Trustee and the Issuer of any action taken by the Collateral
Agent or any Person acting at the direction of the Collateral Agent hereunder or
under any other Financing Document; such notice shall be given prior to the
taking of such action, and such action will be binding upon and deemed to be
taken at the direction of XLCA, the Swap Counterparty and the Trustee.

                  (c)      Direction of Collateral Agent by the Controlling
Party. Notwithstanding anything to the contrary in this Agreement, the
Collateral Agent shall not be required to exercise any rights or remedies under
any of the Financing Documents, take or refrain from taking any discretionary
action thereunder or give any consent under any of the Financing Documents or
enter into any agreement amending, modifying, supplementing or waiving any
provision of any Financing Document unless it shall have been directed to do so
by the Controlling Party.

         11.2     Rights of Collateral Agent.

                  (a)      Collateral Agent May Act Through Agents. Each of the
Collateral Agent and the Trustee may execute or perform any of its duties or
powers hereunder either directly or by or through agents or attorneys, and
neither the Trustee nor the Collateral Agent shall be responsible for any
misconduct or negligence on the part of any agent or attorney appointed with due
care by it hereunder.

                  (b)      Limitation of Liability. Neither the Collateral Agent
nor any of its respective officers, directors, employees, agents,
attorneys-in-fact or affiliates shall be (i) liable for any action lawfully
taken or omitted to be taken by it under or in connection with any Financing
Document (except for its gross negligence or willful misconduct as determined by
a court of competent jurisdiction), or (ii) responsible in any manner to XLCA,
the Swap Counterparty or the Trustee for any recitals, statements,
representations or warranties made by the Issuer, any Project Company or any
representative thereof contained in any Financing Document or in any
certificate, report, statement or other document referred to or provided for in,
or received by the Collateral Agent under or in connection with, any Financing
Document or for the value, validity, effectiveness, genuineness, enforceability
or sufficiency of the Financing Documents or for any failure of the Issuer or
any Project Company to perform its obligations thereunder. The Collateral Agent
shall not be under any obligation to XLCA, the Swap Counterparty or the Trustee
to ascertain or to inquire as to the observance or performance of any of the
agreements contained in, or conditions of, any Financing Document, or to inspect
the properties, books or records of the Issuer.

                  (c)      Reliance by the Collateral Agent. The Collateral
Agent shall be entitled to rely conclusively, and shall be fully protected in
relying, upon any note, writing, resolution, notice, consent, certificate,
affidavit, report (environmental or otherwise), letter, telecopy, telex or
teletype message, statement, order or other document or conversation believed by
it to be genuine and to have been signed, sent or made by the proper Person or
Persons and upon advice and statements of legal counsel (including counsel to
the Issuer), independent accountants and other experts selected by the
Collateral Agent. In connection with any request of the Controlling Party, the
Collateral Agent shall be fully protected in relying conclusively on a
certificate of such Person, signed by an Responsible Officer of such Person. The
Collateral Agent shall be fully

                                       57

<PAGE>

justified in failing or refusing to take any action under any Financing Document
(i) if such action would, in the opinion of the Collateral Agent, be contrary to
law or the terms of this Agreement or the other Financing Documents, (ii) if
such action is not specifically provided for in such Financing Document and it
shall not have received any such advice or concurrence of the Controlling Party,
as it deems appropriate, or (iii) if, in connection with the taking of any such
action that would constitute an exercise of remedies under such Financing
Document, it shall not first be indemnified to its satisfaction by the Issuer
and the Controlling Party against any and all liability and expense which may be
incurred by it by reason of taking or continuing to take any such action. The
Collateral Agent shall in all cases be fully protected in acting, or in
refraining from acting, under any Financing Document in accordance with a
request of the Controlling Party, and such request and any action taken or
failure to act pursuant thereto shall be binding upon the Secured Parties.

                  (d)      Ambiguity or Inconsistency in Financing Documents
with Proposed Actions. If, with respect to a proposed action to be taken by it,
the Collateral Agent shall determine in good faith that the provisions of this
Agreement or any other Financing Document relating to the functions,
responsibilities or powers of the Collateral Agent are or may be ambiguous or
inconsistent, the Collateral Agent shall notify the Controlling Party and the
Issuer, identifying the proposed action and the provisions that it considers are
or may be ambiguous or inconsistent, and may decline either to perform such
function or responsibility or to exercise such power unless it has received
written confirmation that the Controlling Party and, if no Issuer Event of
Default has occurred and is continuing, the Issuer concur in the circumstances
that the action proposed to be taken by the Collateral Agent is consistent with
the terms of this Agreement or is otherwise appropriate. The Collateral Agent
shall be fully protected in acting or refraining from acting upon, or from
omitting to act prior to, the confirmation of the Controlling Party, in this
respect, and such confirmation shall be binding upon the Collateral Agent.

                  (e)      Knowledge of Event of Default. The Collateral Agent
shall not be deemed to have actual, constructive, direct or indirect knowledge
or notice of the occurrence of any Issuer Event of Default unless and until the
Collateral Agent has received a notice or a certificate from the Controlling
Party or the Issuer stating that an Issuer Event of Default has occurred. The
Collateral Agent shall have no obligation whatsoever either prior to or after
receiving such notice or certificate to inquire whether an Issuer Event of
Default has in fact occurred and shall be entitled to rely conclusively, and
shall be fully protected in so relying, on any notice or certificate so
furnished to a Responsible Officer of the Collateral Agent. No provision of this
Agreement shall require the Collateral Agent to expend or risk its own funds or
otherwise incur any financial liability in the performance of any of its duties
hereunder or in the exercise of any of its rights or powers, if it shall have
reasonable grounds for believing that repayment of such funds or indemnity
satisfactory to it against such risk or liability is not reasonably assured to
it. In the event that the Collateral Agent receives such a notice of the
occurrence of any Issuer Event of Default, the Collateral Agent shall give
notice thereof to the Issuer, the Swap Counterparty, XLCA and the Trustee.
Subject to the provisions of this Agreement, the Collateral Agent shall take
such action with respect to such Issuer Event of Default as so directed pursuant
to Section 11.1(c).

                  (f)      No Liability for Clean-up of Hazardous Materials. In
the event the Collateral Agent (or the Trustee, if it is required to acquire
title for any reason) is required to take

                                       58

<PAGE>

any managerial action of any kind with respect to the Collateral, in order to
carry out any fiduciary or trust obligation for the benefit of another, which in
the Collateral Agent's or the Trustee's sole discretion may cause the Collateral
Agent or the Trustee to be considered an "owner or Operator" under the
provisions of CERCLA, or otherwise cause the Collateral Agent or Trustee to
incur liability under CERCLA or any other federal, state or local law, each of
the Collateral Agent and the Trustee reserves the right to, instead of taking
such action, either resign or arrange for the transfer of the title or control
of the asset to a court appointed receiver.

                  Neither the Collateral Agent nor the Trustee shall be liable
to the Issuer or any Project Company or any other Person for any environmental
claims or contribution actions under any federal, state or local law, rule or
regulation by reason of the Collateral Agent's or the Trustee's actions and
conduct as authorized, empowered and directed hereunder or relating to the
discharge, release or threatened release of hazardous materials into the
environment, except in each case to the extent such claims or contribution
actions arise from the gross negligence, bad faith or willful misconduct on the
part of the Collateral Agent or the Trustee.

         11.3     Lack of Reliance on the Agents.

                  (a)      Each of XLCA and the Swap Counterparty expressly
acknowledges that neither the Collateral Agent nor any of its respective
officers, directors, employees, agents or attorneys-in-fact has made any
representations or warranties to it and that no act by the Collateral Agent
hereinafter taken, including any review of the Projects or of the affairs of the
Issuer, shall be deemed to constitute any representation or warranty by the
Collateral Agent to XLCA or the Swap Counterparty. Each of XLCA and the Swap
Counterparty represents to the Collateral Agent that it has, independently and
without reliance upon XLCA or the Swap Counterparty, based on such documents and
information as it has deemed appropriate, made its own appraisal of and
investigation into the business, operations, property, financial and other
condition and creditworthiness of the Projects and the Issuer. Each of XLCA and
the Swap Counterparty also represents that it will, independently and without
reliance upon the Collateral Agent, and based on such documents and information
as it shall deem appropriate at the time, continue to make its own credit
analysis, appraisals and decisions in taking or not taking action under this
Agreement, and to make such investigation as it deems necessary to inform itself
as to the business, operations, property, financial and other condition and
creditworthiness of the Projects and the Issuer. Except for notices, reports and
other documents expressly required to be furnished to XLCA, the Swap
Counterparty and the Trustee by the Collateral Agent hereunder, the Collateral
Agent shall not have any duty or responsibility to provide XLCA, the Swap
Counterparty or the Trustee with any credit or other information concerning the
business, operations, property, financial and other condition or
creditworthiness of the Projects and the Issuer which may come into the
possession of the Collateral Agent or any of its officers, directors, employees,
agents or attorneys-in-fact.

                  (b)      Beyond the exercise of reasonable care in the custody
thereof or as otherwise provided for in the Financing Documents, the Collateral
Agent shall have no duty as to any Collateral in its possession or control or in
the possession or control of any agent or bailee or any income thereon or as to
preservation of rights against prior parties. The Collateral Agent shall be
deemed to have exercised reasonable care in the custody of the Collateral in its
possession if the Collateral is accorded treatment substantially equal to that
which the Collateral

                                       59

<PAGE>

Agent accords its own property, and the Collateral Agent shall not be liable or
responsible for any loss or diminution in the value of any of the Collateral by
reason of the act or omission of any carrier, forwarding agency or other agent
or bailee selected by the Collateral Agent in good faith.

                  (c)      The Collateral Agent shall not be responsible for the
existence, genuineness or value of any of the Collateral or for the validity,
perfection, priority or enforceability of the liens in any of the Collateral,
whether impaired by operation of law or by reason of any action or omission to
act on its part hereunder, except to the extent such action or omission
constitutes gross negligence, bad faith or willful misconduct on the part of the
Collateral Agent, for the validity or sufficiency of the Collateral or any
agreement or assignment contained therein, for the validity of the title of the
Issuer to the Collateral, for insuring the Collateral or for the payment of
taxes, charges, assessments or liens upon the Collateral or otherwise as to the
maintenance of the Collateral. The Collateral Agent shall not be responsible for
filing any financing or continuation statements or recording any documents or
instruments in any public office at any time.

         11.4     Indemnification. The Controlling Party agrees to indemnify and
hold harmless each of the Collateral Agent, and its officers, directors, agents
and attorneys, in their respective capacities as such (to the extent not
reimbursed by the Issuer and without limiting the obligation, if any, of the
Issuer to do so), from and against any and all liabilities, obligations, losses,
damages, penalties, actions, judgments, suits, costs, expenses or disbursements
of any kind whatsoever which may at any time be imposed on, incurred by or
asserted against the Collateral Agent in its capacity as such in any way
relating to or arising out of any Financing Document, or the performance of its
duties as Collateral Agent thereunder or any action taken or omitted by such
Collateral Agent in its capacity as such under or in connection with any of the
foregoing; provided that the Controlling Party shall not be liable for the
payment of any portion of such liabilities, obligations, losses, damages,
penalties, actions, judgments, suits, costs, expenses or disbursements to the
extent that any of the foregoing result from the Collateral Agent's gross
negligence or willful misconduct as determined by a court of competent
jurisdiction. The agreements in this Section 11.4 shall survive the payment or
satisfaction in full of the Obligations.

         11.5     Resignation or Removal of the Collateral Agent. The Collateral
Agent may resign as Collateral Agent upon thirty (30) days' prior written notice
to XLCA, the Swap Counterparty, the Trustee and the Issuer. The Collateral Agent
may be removed at any time following such notice with or without cause by the
Controlling Party, with any such resignation or removal to become effective only
upon the appointment by the Controlling Party of a successor Collateral Agent
under this Section 11.5. If the Collateral Agent shall resign or be removed as
Collateral Agent, then the Controlling Party shall (and if no such successor
shall have been appointed within thirty (30) days of such Collateral Agent's
resignation or removal, such Collateral Agent may) appoint a successor
collateral agent, which successor collateral agent shall be reasonably
acceptable to the Issuer (and shall be deemed acceptable to the Controlling
Party and the Trustee), whereupon such successor collateral agent shall succeed
to the rights, powers and duties of the "Collateral Agent" and the term
"Collateral Agent" shall mean such successor collateral agent effective upon its
appointment, and the former Collateral Agent's rights, powers and duties as
Collateral Agent shall be terminated, without any other or further act

                                       60

<PAGE>

or deed on the part of such former Collateral Agent (except that the resigning
Collateral Agent shall deliver all Collateral, subject to Section 12.4, then in
its possession to the successor Collateral Agent) or the Controlling Party. If
the Issuer withholds its acceptance of such successor Collateral Agent or if an
instrument of acceptance by a successor Collateral Agent shall not have been
delivered to the Collateral Agent within 30 days after: (i) the giving by the
resigning Collateral Agent of such notice of resignation or (ii) the giving of
such notice of removal to the removed Collateral Agent, then the retiring
Collateral Agent may petition, at the expense of the Issuer, any court of
competent jurisdiction for the appointment of a successor Collateral Agent.
After any retiring Collateral Agent's resignation or removal hereunder as
Collateral Agent, the provisions of this Agreement shall inure to its benefit as
to any actions taken or omitted to be taken by it while it was Collateral Agent.

         11.6     Release of Collateral. Notwithstanding anything to the
contrary contained herein, the Collateral Agent is authorized (without any
further action by any Secured Party) to release the Lien of the Collateral
Documents from any portion of the Collateral that is expressly permitted to be
sold, assigned, transferred or otherwise disposed of in accordance with the
terms of this Agreement and the other Financing Documents. The Collateral Agent
shall execute such documents and take such actions as reasonably requested by,
and at the expense of, the Issuer to effect or evidence such release. The
Collateral Agent shall be entitled to receive an Opinion of Counsel (as defined
in the Indenture) in connection with any such release to the effect that the
conditions precedent to such release under the Financing Documents have been
satisfied. Except as otherwise provided in this Agreement or in the other
Financing Documents, neither the Collateral Agent nor any Co-Collateral Agent
shall release any of the Collateral without the prior written consent of the
Controlling Party.

         11.7     Assignment of Rights, Not Assumption of Duties. Anything
herein contained to the contrary notwithstanding, (a) the Issuer shall remain
liable under each of the Financing Documents to which it is a party to the
extent set forth therein to perform all of its duties and obligations
thereunder, (b) the exercise by the Collateral Agent or the Trustee of any of
their rights, remedies or powers hereunder shall not release the Issuer from any
of its duties or obligations under each of the Financing Documents to which it
is a party, and (c) neither the Collateral Agent nor the Trustee shall be
obligated to perform any of the obligations or duties of the Issuer thereunder
or, except as expressly provided herein, to take any action to collect or
enforce any claim for payment assigned hereunder or otherwise.

         11.8     Appointment of Co-Collateral Agent. Notwithstanding any other
provisions of this Agreement, at any time, for the purpose of meeting any legal
requirement of any jurisdiction in which any Collateral may at the time be
located, the Collateral Agent shall have the power and may execute and deliver
all instruments to appoint one or more persons to act as its Co-Collateral Agent
of all or any part of the Collateral, and to vest in such persons, in such
capacity and for the benefit or on behalf of the Secured Parties, such title to
the Collateral, or any part thereof, and subject to the other provisions of this
Section 11.8, such powers, duties, obligations, rights and trusts as the
Collateral Agent may consider necessary or desirable, provided that the
appointment of such Co-Collateral Agent shall be subject to the approval of the
Issuer and the Controlling Party, which approval shall not be unreasonably
withheld, and provided further, that any Co-Collateral Agent shall agree to be
liable to the Secured Parties to the extent the Collateral Agent is so liable
pursuant to this Agreement.

                                       61

<PAGE>

                  All rights and powers, conferred or imposed upon the
Collateral Agent may be conferred or imposed upon and may be exercised or
performed by a Co-Collateral Agent.

                  Any notice, request or other writing given to the Collateral
Agent shall be deemed to have been given to the Co-Collateral Agent, as
effectively as if given to such Co-Collateral Agent. Every instrument appointing
any Co-Collateral Agent shall refer to this Agreement and the conditions of this
section.

                  If any Co-Collateral Agent shall become incapable of acting,
resign or be removed, all of its estates, properties, rights, remedies and
trusts shall vest in and be exercised by the Collateral Agent to the extent
permitted by law.

                  The appointment of a Co-Collateral Agent shall not relieve the
Collateral Agent from any of its obligations hereunder.

                  The Collateral Agent shall not be responsible for any willful
misconduct or negligence on the part of any Co-Collateral Agent appointed with
due care and in good faith pursuant to this Section 11.8.

                  Delivery to the Collateral Agent and/or Trustee of the
financial statements and reports is for informational purposes only and the
Collateral Agent's and/or the Trustee's receipt of such shall not constitute
constructive notice of any information contained therein or determinable from
information contained therein, including the Issuer's compliance with any of its
covenants hereunder (as to which the Collateral Agent and/or the Trustee is
entitle to rely exclusively on officers' certificates).

         11.9     XLCA Confirmation Before Release of Certain Funds.
Notwithstanding anything to the contrary in any Financing Document, if XLCA is
the Controlling Party, any funds, cash or obligations to be released in
accordance with the terms of the Depositary Agreement to any Financing Party or
any other Person upon the cure of any Funds Block Condition shall not be so
released (and the Collateral Agent shall not direct the Depositary Agent to
release such funds, cash or obligations) unless XLCA shall have confirmed, in
its absolute discretion, in writing to the Collateral Agent that such Funds
Block Condition has been cured; provided that if a certificate as to the cure of
a Funds Block Condition is delivered to the Collateral Agent and to XLCA in
accordance with the terms of the Financing Documents and requests a release of
funds, cash or obligations as of a specified date, the failure of XLCA to
confirm the cure of such Funds Block Condition on or prior to such specified
date shall, if (notwithstanding anything to the contrary in any Financing
Document) such certificate shall have been received by XLCA at least 5 Business
Days prior to such specified date, be deemed to be such confirmation.

registered or certified with return receipt requested, (d) if sent by prepaid
telegram or by facsimile or (e) other electronic means (including electronic
mail) confirmed by facsimile or telephone (except to the Collateral Agent).
Notice so given shall be effective upon receipt by the addressee, except that
communication or notice so transmitted by facsimile or other direct electronic
means shall be deemed to have been validly and effectively given on the day (if
a Business Day and, if not, on the next following Business Day) on which it is

times be treated as collateral security for the payment of the Issuer's
obligations under the Insurance and Reimbursement Agreement, the Bonds, the Swap
Agreement and all other obligations of the Issuer under this Agreement and the
other Financing Documents, and the Issuer hereby pledges to the Collateral
Agent, for the benefit of the Secured Parties, and grants the Collateral Agent a
first priority security interest in and to all such deposits, sums, securities
or other property (subject to Issuer Permitted Liens). Regardless of the
adequacy of any other collateral, the Collateral Agent may execute or realize on
its security interest in any such deposits or other sums credited by or due from
the Collateral Agent to the Issuer, may apply any such deposits or other sums to
or set them off against Obligations at any time after the occurrence and during

power or remedy accruing to XLCA, the Swap Counterparty or the Trustee or any
other Secured Party upon the occurrence of any Issuer Event of Default or Issuer
Inchoate Default or any Project Event of Default or Project Inchoate Default or
any breach or default of any other Party under this Agreement or any other
Financing Document shall impair any such right, power or remedy of any Secured
Party, 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

                                       67

<PAGE>

waiver of any single Issuer Event of Default, Issuer Inchoate Default, Project
Event of Default or Project Inchoate Default or other breach or default be
deemed a waiver of any other Issuer Event of Default, Issuer Inchoate Default,
Project Event of Default or Project Inchoate Default or other breach or default
theretofore or thereafter occurring. Any waiver, permit, consent or approval of
any kind or character on the part of the Collateral Agent, XLCA, the Swap
Counterparty and/or the Trustee of any Issuer Event of Default, Issuer Inchoate
Default, Project Event of Default or Project Inchoate Default or other breach or
default under this Agreement or any other Financing Document, or any waiver on
the part of the Collateral Agent, XLCA, the Swap Counterparty and/or the Trustee
of any provision or condition of this Agreement or any other Financing Document,
must be in writing and shall be effective only to the extent in such writing
specifically set forth. All remedies, either under this Agreement or any other
Financing Document or by law or otherwise afforded to the Collateral Agent,
XLCA, the Swap Counterparty or the Trustee and the other Secured Parties shall
be cumulative and not alternative.

         12.4     Costs, Expenses and Attorneys' Fees. Without duplication of
any other provision of any Financing Document regarding the payment of fees,
costs and/or expenses, the Issuer will pay to each of XLCA, the Swap
Counterparty, the Trustee and the Collateral Agent (a) all of their reasonable
costs and expenses in connection with the preparation, negotiation, closing and
administering of this Agreement and the other Financing Documents, and the
documents contemplated hereby or thereby, including the reasonable fees,
expenses and disbursements of attorneys and agents retained by such Persons in
connection with the preparation of such documents and any amendments hereof or
thereof, or the preparation, negotiation, closing, administration or enforcement
of any Financing Document or any rescission or restriction thereof, (b) the
reasonable fees, expenses and disbursements of the Independent Consultants and
any other engineering or insurance consultants to XLCA, the Swap Counterparty
and the Trustee and incurred in connection with the Financing Documents or the
Transaction prior to the Closing Date, and (c) the travel and out-of-pocket
costs incurred by such Persons following the Closing Date (provided that any
such costs described in this clause (c), or related group of such costs, in
excess of $10,000 shall be approved by the Issuer). Without limiting the
foregoing, the Issuer will reimburse XLCA, the Swap Counterparty, the Trustee
and the Collateral Agent for all costs and expenses, including reasonable
attorneys' fees and those of their agents, expended or incurred by such Persons
in enforcing this Agreement or the other Financing Documents in connection with
an Issuer Event of Default, in actions for declaratory relief in any way related
to this Agreement or in collecting any sum which becomes due to such Persons on
the Policy, the Swap Policy, the Bonds or otherwise under the Financing
Documents. The provisions of this Section 12.4 shall survive the termination of
this Agreement.

         12.5     Entire Agreement. This Agreement and any agreement, document
or instrument attached hereto or referred to herein integrate all the terms and
conditions mentioned herein or incidental hereto and supersede all oral
negotiations and prior writings in respect to the subject matter hereof. In the
event of any conflict between the terms, conditions and provisions of this
Agreement and any such other agreement, document or instrument, the terms,
conditions and provisions of this Agreement shall prevail.

         12.6     Governing Law. This Agreement, and any instrument or agreement
required hereunder (to the extent not otherwise expressly provided for therein),
shall be governed by, and

                                       68

<PAGE>

construed under, the laws of the State of New York, without reference to
conflicts of laws (other than Section 5-1401 of the New York General Obligations
Law).

         12.7     Severability. In case any one or more of the provisions
contained in this Agreement should be invalid, illegal or unenforceable in any
respect, the validity, legality and enforceability of the remaining provisions
shall not in any way be affected or impaired thereby.

         12.8     Headings. Headings have been inserted in this Agreement as a
matter of convenience for reference only and such article and section headings
shall not be used in the interpretation of any provision of this Agreement.

         12.9     No Partnership, etc. XLCA, the Swap Counterparty, the Trustee,
the Collateral Agent, the Issuer and the Project Companies intend that the
relationship between them shall be solely that of independent contracting
parties. Nothing contained in this Agreement, the Policy, the Swap Policy, the
Insurance and Reimbursement Agreement, the Bonds, the Indenture or any other
Financing Document shall be deemed or construed to create a partnership,
tenancy-in-common, joint tenancy, joint venture or co-ownership by or between
XLCA, the Swap Counterparty, the Trustee, the Collateral Agent, the Issuer, the
Project Companies or any other Person. XLCA, the Swap Counterparty, the
Collateral Agent and the Trustee shall not be in any way responsible or liable
for the debts, losses, obligations or duties of the Project Companies, the
Issuer or any other Person with respect to any Project or otherwise. All
obligations to pay real property or other taxes, assessments, insurance premiums
and all other fees and charges arising from the ownership, operation or
occupancy of any Project, and to perform all obligations and other agreements
and contracts relating to any Project or any other asset or liability of any
Project Company or the Issuer, shall be the sole responsibility of the Project
Companies and the Issuer.

         12.10    Limitation on Liability. No claim shall be made by any Project
Company, the Issuer, NRG Energy or any of their Affiliates against XLCA, the
Swap Counterparty, the Trustee, the Collateral Agent, any other Secured Party or
any of their respective 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 the Issuer 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.

         12.11    Waiver of Jury Trial. THE PARTIES HERETO 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 FINANCING DOCUMENT, OR ANY COURSE
OF CONDUCT, COURSE OF DEALING, STATEMENTS (WHETHER VERBAL OR WRITTEN) OR ACTIONS
OF THE PARTIES HERETO. THIS PROVISION IS A MATERIAL INDUCEMENT FOR XLCA AND THE
TRUSTEE TO ENTER INTO THIS AGREEMENT.

         12.12    Consent to Jurisdiction. XLCA, the Swap Counterparty, the
Trustee, the Collateral Agent, the Issuer and the Project Companies agree that
any legal action or proceeding by or against the Issuer or any Project Company
or with respect to or arising out of this Agreement, the Policy, the Swap
Policy, the Insurance and Reimbursement Agreement, the Bonds, the Indenture or
any other Financing 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 XLCA, the Swap Counterparty,
the Trustee or the Collateral Agent may elect. By execution and delivery of this
Agreement, XLCA, the Trustee, the Collateral Agent, the Issuer and the Project
Companies accept, for themselves and in respect of their property, generally and
unconditionally, the jurisdiction of the aforesaid courts. XLCA, the Swap
Counterparty, the Trustee, the Collateral Agent, the Issuer and the Project
Companies irrevocably consent to the service of process out of any of the
aforementioned courts in any manner permitted by law. Nothing herein shall
affect the right of XLCA, the Trustee or the Collateral Agent to bring legal
action or proceedings in any other competent jurisdiction, including judicial or
non-judicial foreclosure of any Mortgage. XLCA, the Swap Counterparty the
Trustee, the Collateral Agent, the Issuer and the Project Companies 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 the Issuer based upon the assertion that the rate of interest
charged by XLCA or owing to the Bonds under this Agreement, the Policy, the Swap
Policy, the Insurance and Reimbursement Agreement, the Indenture and/or the
other Financing Documents is usurious. XLCA, the Swap Counterparty, the Trustee,
the Collateral Agent, the Issuer and the Project Companies hereby waive any
right to stay or dismiss any action or proceeding under or in connection with
any or all of any Project, this Agreement or any other Financing Document
brought before the foregoing courts on the basis of forum non-conveniens. The
Issuer and each Project Company hereby irrevocably appoints and designates
Corporation Service Company, as its true and lawful attorney and duly authorized
agent for acceptance of service of legal process, and agrees to maintain
Corporation Service Company as such. The Issuer and each Project Company agrees
that service of such process upon such person shall constitute personal service
of such process upon it.

         12.13    Usury. Nothing contained in this Agreement or any other
Financing Document shall be deemed to require the payment of interest or other
charges by the Issuer or any other Person in excess of the amount which any
Secured Party may lawfully charge under any applicable usury laws. In the event
any Secured Party 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 such Secured Party, be returned to the Issuer or
credited against the Obligations.

         12.14    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. Neither the Issuer nor any Project Company

         12.15    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,

without prejudice to Section 12.17 or Section 12.18, until the date that is 366

obligations under the Financing Documents shall automatically be reinstated if
for any reason any payment made by or on behalf of the Issuer under any

of any proceedings in bankruptcy, 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.

         12.18    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 Financing Documents
shall be considered to have been relied upon by the parties hereto and shall
survive the execution and delivery of this Agreement and the other Financing
Documents and the issuance of the Policy, the Swap Policy and the Bonds.
Notwithstanding anything in this Agreement or implied by law to the contrary,
the agreements of the Issuer and the Project Companies set forth in Sections
9.1, 10.1 and 12.4 and Article 11 and the agreements of the Collateral Agent
contained in Article 11 shall survive the payment and performance of the Bonds
and other Obligations and the termination of this Agreement as shall such other
provisions in any Financing Document expressly stated to do so.

         12.19    Partial Termination. Upon the occurrence of a Project Release
Event with respect to any Project Company, all of such Project Company's
obligations (including its Guaranty) hereunder and under the other Financing
Documents shall terminate and the Project Company Collateral of such Project
Company shall no longer be subject to the Lien of the Collateral Documents. A
Project Release Event with respect to the Rockford II Project Company shall be
deemed also to be a Project Release Event with respect to the Rockford II
Equipment Company. Notwithstanding anything to the contrary in this Agreement,
each Secured Party agrees to

                                       71

execute such documents, and take such other actions, as reasonably requested by,
and at the expense of, the Issuer to effect and evidence such termination and
release.

         12.20    No XLCA Liability or Duties. Neither XLCA nor any of its
officers, directors or employees shall be liable or responsible for: (a) the use
which may be made of each of the Policies by or for the Collateral Agent, the
Swap Counterparty, the Depositary Agent, the Trustee, any depositary, any bank,
any Bondholder or other purchaser of Bonds or any other Person or for any acts
or omissions of any such Person in connection therewith; (b) the validity,
sufficiency, accuracy or genuineness of documents or of any endorsements thereon
delivered to XLCA (or its Fiscal Agent) in connection with any claim under
either of the Policies, or of any signatures thereon, even if such documents or
signatures should in fact prove to be in any or all respects invalid,
insufficient, fraudulent or forged or (c) any acts or omissions to act of the
Issuer, any Project Company, the Swap Counterparty, the Collateral Agent, the
Depositary Agent, the Trustee, any Bondholder or any other person in connection
with the Collateral. In furtherance and not in limitation of the foregoing, XLCA
(or its Fiscal Agent) may accept documents that appear on their face to be in
order, without responsibility for further investigation. In making any decision
or determination, taking any action or omitting to take any action, giving or
withholding any consent, waiver or agreement (whether as Controlling Party or
otherwise) in respect of matters arising under or in connection with any
Financing Document and in each other respect, XLCA shall have no implied duty to
any other party to this Agreement or any other Person and shall act at all times
as it shall, in its absolute, discretion see fit.

                                      H-2

<PAGE>

watercraft liability policies. Total Limits can be maintained through

an amount not less than $10,000,000 for all owned, non-owned and hired aircraft,
fixed wing or rotary, used in connection with the Project Company's activities.

                  (h)      Such other or additional insurance (as to risks
covered, policy amounts, policy provisions or otherwise) as, under Prudent
Utility Practices in the reasonable judgment of XLCA in consultation with the
Insurance Consultant (if XLCA is the Controlling Party) or the Trustee in
consultation with the Insurance Consultant, but without any need for the consent
of the Bondholders (if XLCA is not the Controlling Party), are from time to time
insured against for property and facilities similar in nature.

                  (i)      All major contractors and subcontractors, shall,
prior to performing work for any Project Company, supply proper evidence of
insurance as set forth in paragraphs 1(b), 1(c), and 1(d), above. If required by
Contract, the contractor and/or subcontract may also be required to provide
coverage for the exposures noted in 1(a), above. If they are required to provide
those policies, then Project Company must be included on the Policy as a Loss
Payee, as its interest may appear. The Project Company shall use its discretion
in requiring higher limits should the exposure merit limits greater than those
set forth above. Such insurance, with the exception of workers compensation,
supplied by these parties shall:

                           (i)      add the Project Company and the Secured
                  Parties as additional insureds;

                           (ii)     be primary as respects insurance provided by
                  the Project Company and the Secured Parties;

                           (iii)    waive rights of subrogation against the
                  Project Company and the Secured Parties;

                           (iv)     continue in force until obligations of the
                  applicable contractor or subcontractor to the Project Company
                  are fulfilled.

With respect to the Workers' Compensation coverage of the
contractor/subcontractor, evidence of such coverage shall be satisfactory if
that evidence reflects that subrogation has been waived in favor of the Project
Company.

                  2.       All policies wherein the Secured Parties have an
insurable interest shall insure the interests of the Collateral Agent for the
benefit of the Secured Parties as well as the Project Company and all policies,
with the exception of workers compensation insurance, shall name the Secured
Parties as additional insureds. Each policy shall provide for a waiver of
subrogation against the Secured Parties and the Project Company. Each such
policy shall provide that if any premium or installment is not paid when due, or
if such insurance is to be cancelled, terminated or materially changed in a
manner that adversely affects the Secured Parties , the insurers (or their
representatives) will promptly notify the Project Company and the Collateral
Agent and any such cancellation, termination or change shall not be effective
until 60

                                      H-3

<PAGE>

days after receipt of such notice by the Controlling Party and the additional
insureds, with the exception of non-payment of premium which will be 10 days
notice.

                  3.       All policies of insurance required to be maintained
pursuant to Section 1(a) shall provide that the proceeds of such policies shall
be payable solely to the Collateral Agent pursuant to a standard first mortgage
endorsement substantially equivalent to the Lenders Loss Payable Endorsement
Form CP 1218019. All policies (other than in respect to liability or workers
compensation insurance) shall insure the interests of the Secured Parties
regardless of any breach or violation by the Project Company of warranties,
declarations or conditions contained in such policies, any action or inaction of
the Project Company or others, or any foreclosure relating to the Project or any
change in ownership of all or any portion of the Project, subject to the review
and approval of Underwriters (the foregoing may be accomplished by the use of
the Lender Loss Payable Endorsement required above).

                  4.       In the event that the Project Company fails to
respond in a reasonable, timely and appropriate manner to take any steps
necessary or reasonably requested by the Controlling Party to collect from any
insurers for any loss covered by any insurance required to be maintained by this
Exhibit C, the Controlling Party may instruct the Collateral Agent to make all
proofs of loss, adjust all claims and/or receive all or any part of the proceeds
of the foregoing insurance policies, either in the name of the Collateral Agent,
on behalf of the Secured Parties, or the name of the Project Company; provided,
however, that the Project Company shall, upon request and at the Project
Company's own cost and expense, make all proofs of loss and take all other steps
necessary or reasonably requested to collect from insurers for any loss covered
by any insurance required to be obtained by this Exhibit C.

                  5.       In the event any insurance (including the limits or
deductibles thereof) hereby required to be maintained, other than insurance
required by law to be maintained, shall not be available and commercially
feasible in the commercial insurance market, the Project Company shall not be
required to maintain such insurance if it delivers to the Controlling Party (a)
a certificate of the Insurance Consultant to the effect that such insurance is
not available and commercially feasible in the commercial insurance market and
(b) a certificate of a Responsible Officer of the Project Company to the effect
that the failure to maintain such insurance could not reasonably be expected to
have a Project Material Adverse Effect

                  6.       In the event that any policy is written on a
"claims-made" basis and such policy is not renewed or the retroactive date of
such policy is to be changed, the Project Company shall obtain for each such
policy or policies the broadest basic and supplemental extended reporting period
coverage or "tail" reasonably available in the commercial insurance market for
each such policy or policies, and shall provide the Controlling Party with
evidence that such basic and supplemental extended reporting period coverage or
"tail" has been obtained.

                           GENERAL SUBORDINATION TERMS

                  All Debt incurred by the Issuer under paragraph (b) of the
definition of Issuer Permitted Debt or by a Project Company under paragraph (e)
of the definition of Project Company Permitted Debt shall be subject to the
following terms and conditions, which shall be incorporated in a written
agreement between the Issuer or such Project Company, as the case may be, and
the Person(s) to which any such Debt is owed:

                  (a)      For purposes of these terms of subordination (these
"Subordination Terms"), the "Senior Debt" shall mean the Obligations. Unless
otherwise defined herein, capitalized terms used herein have the meanings
provided in the Common Agreement, (as amended, amended and restated,
supplemented or otherwise modified from time to time), dated as of June 18, 2002
among (1) XL Capital Assurance Inc., a New York stock insurance company, (2)
Goldman Sachs Mitsui Marine Derivative Products, L.P., a Delaware limited
liability company, (3) Law Debenture Trust Company of New York, as successor
trustee to The Bank of New York for the benefit of the Bondholders (the
"Trustee"), (4) The Bank of New York, as collateral agent for the benefit of the
Secured Parties (in such capacity, the "Collateral Agent"), (5) NRG Peaker
Finance Company LLC, a Delaware limited liability company, as Issuer (the
"Issuer"), and (6) each party thereto identified as a Project Company on the
signature pages thereto (each a "Project Company" and, collectively, the
"Project Companies").

                  (b)      [INSERT "NRG PEAKER FINANCE COMPANY LLC" OR NAME OF
PROJECT COMPANY] (the "Debtor"), for itself and its successors and assigns,
covenants and agrees and each holder of the indebtedness evidenced by [DESCRIBE
INDEBTEDNESS DOCUMENTATION] ("Subordinated Debt") by its acceptance thereof
likewise covenants and agrees that the payment of the principal of, and interest
on, and all other amounts owing in respect of, the Subordinated Debt is hereby
expressly subordinated, to the extent and in the manner herein set forth, to the
prior payment in full in cash or discharge in full in cash of all Senior Debt.
The subordination provisions set forth herein shall constitute a continuing
offer to all persons who, in reliance upon such provisions, become holders of,
or continue to hold, Senior Debt, and such provisions are made for the benefit
of the holders of Senior Debt, and such holders are hereby made obligees
hereunder to the same extent as if their names were written herein as such, and
they and/or each of them may proceed to enforce such provisions as a third party
beneficiary.

                  (c)      Unless and until all Senior Debt shall have been paid
in full in cash in accordance with its terms and all obligations in respect
thereof shall have terminated, the Debtor shall not, directly or indirectly,
make or agree to make any payment (in cash or property, by set-off or
otherwise), direct or indirect, of or on account of any Subordinated Debt (or
any Debt subordinated thereto), and no such payment shall be accepted by any
holder of Subordinated Debt, unless such payment is made with funds which the
Issuer or any Project Company is permitted to distribute from the Distribution
Account in accordance with Section 4.6 of the Depositary Agreement.

<PAGE>

                  (d)      Upon (i) any acceleration of the principal amount due
on any Subordinated Debt or (ii) any payment or distribution of assets of the
Debtor of any kind or character, whether in cash, property or securities, to
creditors upon any dissolution or winding up or total or partial liquidation or
reorganization of the Debtor, whether voluntary or involuntary or in bankruptcy,
insolvency, receivership or similar proceedings, then and in any such event all
principal and interest and all other amounts due or to become due upon all
Senior Debt (including, without limitation, all interest accruing after the
commencement of any bankruptcy, insolvency, receivership or similar proceeding
at the rate provided in the Financing Documents whether or not such interest is
an allowed claim in such proceeding) shall first be paid in full in cash and all
obligations in respect thereof shall have been terminated before any holder of
Subordinated Debt shall be entitled to retain any assets so paid or distributed
in respect of the Subordinated Debt (for principal, interest or otherwise); and,
upon any such dissolution or winding up or liquidation or reorganization, any
payment or distribution of assets of the Debtor of any kind or character,
whether in cash, property or securities, to which the holders of the
Subordinated Debt would be entitled, except as otherwise provided herein, shall
be paid by the Debtor or by any receiver, trustee in bankruptcy, liquidating
trustee, agent or other person, corporation, partnership or other entity making
such payment or distribution, or by the holders of the Subordinated Debt if
received by them, to the Trustee for distribution to the holders of Senior Debt
or their representatives, to the extent necessary to pay all Senior Debt in full
in cash, after giving effect to any concurrent payment or distribution to or for
the benefit of the holders of Senior Debt, before any payment or distribution is
made to the holders of the Subordinated Debt.

                  (e)      The holders of the Subordinated Debt irrevocably
authorize and empower (without imposing any obligation on) each holder of Senior
Debt and such holder's representatives, under the circumstances set forth in
paragraph (d) above, to demand, sue for, collect and receive every such payment
or distribution described therein and give acquittance therefor, to file claims
and proofs of claims in any statutory or nonstatutory proceeding, to vote such
Senior Debt holder's ratable share of the full amount of the Subordinated Debt
in its sole discretion in connection with any resolution, arrangement, plan of
reorganization, compromise, settlement or extension and to take all such other
action (including, without limitation, the right to participate in any
composition of creditors and the right to vote such Senior Debt holder's ratable
share of the Subordinated Debt at creditors' meetings for the election of
trustees, acceptances of plans and otherwise), in the name of the holders of the
Subordinated Debt or otherwise, as such Senior Debt holder or its
representatives may deem necessary or desirable for the enforcement of these
Subordination Terms. The holders of the Subordinated Debt shall execute and
deliver to each holder of Senior Debt and such Senior Debt holder's
representatives all such further instruments confirming the foregoing
authorization, and all such powers of attorney, proofs of claim, assignments of
claim and other instruments, and shall take all such other actions as may be
requested by such holder of Senior Debt or such holder's representatives in
order to enable such holder or such representative to enforce all claims upon or
in respect of such holder's ratable share of the Subordinated Debt.

                  (f)      Should any payment or distribution be collected or
received by any holder of Subordinated Debt and such collection or receipt is
not expressly permitted by these Subordination Terms, such holder shall
forthwith turn over the same to the Trustee in the form received (except for the
endorsement or the assignment of such holder when necessary) and,

                                       M-2

<PAGE>

until so turned over, the same shall be held in trust by such holder as the
property of the holders of Senior Debt.

                  (g)      No holder of the Subordinated Debt shall, without the
prior written consent of the Controlling Party, have any right to demand payment
of, accelerate the maturity of, or otherwise enforce any right or remedy in
respect of any Subordinated Debt or commence or prosecute any action thereon
until all Senior Debt is paid in full in cash and all obligations in respect
thereof have been terminated.

                  (h)      Until all Senior Debt has been paid in full in cash
and all obligations in respect thereof have been terminated, the holders of the
Subordinated Debt will not, without the prior written consent of the Controlling
Party, commence or join with any other person, corporation, partnership or other
entity in commencing any proceeding against the Debtor or any other person,
corporation, partnership or other entity with respect to the Subordinated Debt
under any bankruptcy, reorganization, readjustment of debt, dissolution,
receivership, liquidation or insolvency law or statute now or hereafter in
effect in any jurisdiction, nor shall the holders of the Subordinated Debt,
without the prior written consent of the Controlling Party, participate in any
assignment for benefit of creditors, compositions or arrangements with respect
to the Debtor's obligations with respect to the Subordinated Debt.

                  (i)      Subject to the payment in full in cash of all Senior
Debt and the termination of all obligations in respect thereof, the holders of
the Subordinated Debt shall be subrogated (equally and ratably with the holders
of all indebtedness of the Debtor that by its express terms is subordinated to
Senior Debt to the same extent as the Subordinated Debt is subordinated and that
is entitled to like rights of subrogation) to the rights of the holders of
Senior Debt to receive payments or distributions of assets of the Debtor made on
the Senior Debt until the Subordinated Debt shall be paid in full; provided that
nothing herein contained shall be intended to assign or grant to any holder of
Subordinated Debt, or subrogate any such holder to, any right of a holder of
Senior Debt as a mortgagee, secured party or other lien or pledgeholder of any
property of the Debtor that secures any Senior Debt.

                  (j)      The above provisions are not intended to impair as
between the Debtor, its creditors other than the holders of Senior Debt, and the
holders of the Subordinated Debt, the obligation of the Debtor, which is
absolute and unconditional, to pay to the holders of the Subordinated Debt, as
and when the same shall become due and payable in accordance with its terms,
principal and interest thereon, subject to the rights of the holders of Senior
Debt as provided in these Subordination Terms, or to affect the relative rights
of the holders of the Subordinated Debt and creditors of the Debtor other than
the holders of Senior Debt.

                  (k)      Application of these Subordination Terms to the
Subordinated Debt, the subordination effected thereby and the rights of the
holders of the Senior Debt shall not be affected by (i) any amendment of or
addition or supplement to any Operative Document or any Senior Debt or any
instrument or agreement relating thereto or providing collateral security for
any Senior Debt, (ii) any exercise or non-exercise of any right, power or remedy
under or in respect of any Operative Document or any Senior Debt or any
instrument or agreement relating thereto, or any release of any collateral
securing any Senior Debt, or (iii) any waiver, consent, release, indulgence,
extension, renewal, modification, delay or any other action, inaction or

                                       M-3

<PAGE>

omission in respect of any Operative Document or any Senior Debt or any
instrument or agreement relating thereto or providing collateral security for
any Senior Debt; in each case whether or not any holders of any Subordinated
Debt shall have had notice or knowledge of any of the foregoing.

                  (l)      Upon any payment or distribution of assets of the
Debtor referred to in these Subordination Terms, the holders of Subordinated
Debt shall be entitled to rely upon any order or decree entered by any court of
competent jurisdiction in which such insolvency, bankruptcy, receivership,
liquidation, reorganization, dissolution, winding up or similar case or
proceeding is pending, or a certificate of the trustee in bankruptcy, receiver,
liquidating trustee, custodian, assignee for the benefit of creditors, agent or
other Person making such payment or distribution, delivered to the holders of
Subordinated Debt, for the purpose of ascertaining the Persons entitled to
participate in such payment or distribution, the holders of Senior Debt and
other indebtedness of the Debtor, the amount thereof or payable thereon, the
amount or amounts paid or distributed thereon and all other facts pertinent
thereto or to these Subordination Terms.

                  (m)      The following provision shall at all times be part of
each instrument or debt security evidencing or representing any Subordinated
Debt:

                  "The principal of and interest on the indebtedness evidenced
                  hereby are postponed, subordinated and junior in right of
                  payment to certain "Senior Debt", as defined in the [IDENTIFY
                  THESE SUBORDINATION TERMS], on the terms set forth in such
                  Subordination Terms. The provisions of such Subordination
                  Terms used therein are hereby incorporated herein as if set
                  forth at length herein. Each subsequent holder and transferee
                  hereof shall be bound, to the extent of its interest herein,
                  by the obligations set forth in such provisions applicable to
                  a holder hereof."

                  (n)      Notwithstanding anything to the contrary in these
Subordination Terms or the agreement into which they are incorporated, these
Subordination Terms may be waived, modified, amended or otherwise changed only
if and as set forth in a written agreement signed by the parties hereto and the
Controlling Party.

                  (o)      These Subordination Terms shall be governed by, and
construed in accordance with, the laws of the State of New York.

                  (p)      Each party hereto, for itself and its successors and
assigns, and each third party beneficiary hereof (by acceptance of the benefits
hereof) hereby (i) irrevocably and unconditionally submits, for itself and its
property, to the exclusive jurisdiction of the Supreme Court of the State of New
York sitting in New York County and of the United States District Court for the
Southern District of New York, and any appellate court from any thereof, in any
action or proceeding arising out of or relating to these Subordination Terms,
(ii) irrevocably and unconditionally agrees that all claims in respect of any
such action or proceeding shall be heard and determined in such New York State
or, to the extent permitted by law, in such Federal court, and (iii) agrees that
a final judgment in any such action or proceeding shall be conclusive and may be
enforced in other jurisdictions and courts by suit on the judgment or in any
other manner provided by law; provided, that this clause (p) shall not impair or
diminish any right that any

                                       M-4

party or third party beneficiary may otherwise have to bring any action or
proceeding relating to these Subordination Terms in the courts of any other

              MAJOR MAINTENANCE RESERVE ACCOUNT FUNDING GUIDELINES

         The funds deposited in the Major Maintenance Reserve Account ("MMRA")
are to be used for three principal types of major maintenance ("MM") activities:
combustion inspections ("Cis"), hot gas path inspections ("HGPs") and major
overhauls or inspections ("Mos"). The manufacturers of combustion turbines
establish and periodically update the frequencies at which each of these
activities should be performed on each of the model types they manufacture.
These frequencies are defined in terms of either equivalent operating
hours/factored hours ("EOH" or "FH") or equivalent starts/factored starts ("ES"
or "FS"), or a combination of both (e.g., the measure that yields the most
frequent MM activity). The manufacturers also establish and periodically update
the equations that are to be used to calculate EOH and/or ES for each of their
models. Combining 1) the estimates of the cost of each MM activity with 2)
information about the actual operating hours and starts and the adjustment
variables (e.g., the actual number of trips) during a particular period yields
an estimate of the cost of the future MM activities to be incurred during the
specific period.

         The amount of MMRA funding required for each Project per Factored
Start, Equivalent Operating Hour or Equivalent Start for fiscal year 2003 is set
forth in the table below. Equivalent Starts, Factored Starts or Equivalent
Operating Hours shall all be calculated in accordance with the equipment
manufacturer's most current maintenance guidelines.

BAYOU COVE

Each Factored Start of a unit at the Bayou Cove Project requires a deposit of
$3,500 into the MMRA. This figure shall be adjusted annually at a rate pursuant
to the calculation in Exhibit A attached hereto.

As of 2003, major maintenance activity frequencies and EOH/ES definitions for GE
7EAs at the Bayou Cove Project are specified in Heavy-Duty Gas Turbine Operating
and Maintenance Considerations, published by GE Power Systems in January 2003
(Document GER-3620J). These frequencies are as follows (Document GER-3620J at
p. 32):

     -   CIs - 12,000 Factored Hours (FH; GE's label for EOH) or 450 Factored
         Starts (FS), whichever yields the most frequent inspections.

     -   HGPs - 24,000 FHs or 1,200 FSs, whichever yields the most frequent
         inspections.

     -   MOs - 48,000 FHs or 2,400 FSs, whichever yields the most frequent
         inspections.

For the units of the Bayou Cove Project that burn gas without water/steam
injection, the definitions of FH and FS for the determination of HGP frequency
are as follows:

                                      O-8

<PAGE>

     -   FH = base-load operating hours + 6 x peak-load operating hours

     -   FS = .5 x part-load starts + base-load starts + 1.3 x peak-load starts
              + 20 x emergency starts + 2 x fast-load starts +(Sigma) T(i) a(i)

Ti means the number of trips at each load level, and ai means the severity
factor for a trip at each load level. The severity factors are provided in a
graph on p. 13 of Document GER-3620J which are equal to the lesser of 8 or 2 + 5
* % Load (e.g., at 40% of load, the factor is 2 + 5 x .40 = 4). FH and FS for
the determination of CI and MO frequencies are defined in the same way.

STERLINGTON

Each Factored Start of a unit at the Sterlington Project requires a deposit of
$900 into the MMRA. This figure shall be adjusted annually at a rate pursuant to
the calculation in Exhibit A attached hereto.

As of 2003, the relevant manual for major maintenance activity frequencies and
EOH/ES definitions for GE Frame 5 CTs is Document GER-3620J as described above.
Although Document GER-3620J does not include specifications for frequencies and
definitions for these particular models, GE staff have verbally recommended that
the frequencies for Model 5001PA and the FH/FS definitions for Frame 6/7/9
models specified in Document GER-3620J be used for these units. These
frequencies are as follows (Document GER-3620J at p. 32):

     -   CIs - 12,000 FHs or 800 FSs, whichever yields the most frequent
         inspections.

     -   HGPs - 1,200 FSs

     -   MOs - 48,000 FHs or 2,400 FSs, whichever yields the most frequent
         inspections.

The definitions of FHs and FSs are the same as those for 7EA units at the Bayou
Cove Project.

ROCKFORD I AND ROCKFORD II

Each Equivalent Operating Hour for a unit at the Rockford I Project and the
Rockford II Project each requires a deposit of $440 into the MMRA. This figure
shall be adjusted annually at a rate pursuant to the calculation in Exhibit A
attached hereto.

As of 2003, major maintenance frequencies and EOH definitions for Siemens
V84.3A(2) CTs are specified in Siemens Document 970602GSR, Maintenance
Intervals/Equivalent Operating Hours as follows:

     -   Minor inspections (Siemens' label for CIs) - 4,000 EOHs

     -   HGPs - 25,000 EOHs

     -   MOs - 50,000 EOHs

For the units of the Rockford I Project and the Rockford II Project that burn
gas:

     -   EOH = 10 x starts + 10 x rapid temperature changes (including a trip) +
         operating hours.

                                      O-9

BIG CAJUN

Each Equivalent Start of a unit at the Big Cajun Project requires a deposit of
$6,670 into the MMRA. This figure shall be adjusted annually at a rate pursuant
to the calculation in Exhibit A attached hereto.

As of 2003, major maintenance activity frequencies and EOH/ES definitions for
Siemens Westinghouse W501-D5A CTs are specified in Service Bulletin 36803:
Combustion Turbine Maintenance and Inspection Intervals, published by SW Power
Corporation in December 2000 (Service Bulletin 36803). These frequencies are as
follows (Service Bulletin 36803 at p. 12):

     -   CIs - 8,000 EOHs or 400 ESs, whichever yields the most frequent
         inspections.

     -   HGPs - 24,000 EOHs or 800 ESs, whichever yields the most frequent
         inspections.

     -   MOs - 48,000 EHs or 1,600 ESs, whichever yields the most frequent
         inspections.

For the units of the Big Cajun Project that burn gas, EOH (Service Bulletin
36803 at p. 15) and ES (Service Bulletin 36803 at pp 17-18) are defined as
follows:

     -   EOH = base-load hours + 3 x peak-load hours

     -   ES = normal starts + 10 x intermediate starts + 20 x fast starts +
         fired aborts + (SIGMA) T(i) a(i) + (SIGMA) C(i) b(i)

T(i) means the number of trips at various load levels, a(i) means the severity
factor associated with a trip from each load level, C(i) means a load change of
various magnitude, and b(i) means the severity factor associated with a load
change of each magnitude. The trip severity factors are as follows:

     -   From 51-100% of load - 20

     -   From 31-50% of load - 14

     -   From 16-20% of load - 7

     -   From 1-15% of load - 4

                                      O-10

                             ADJUSTMENT OF DEPOSITS

The initial deposit into the MMRA for each Factored Start (with respect to the
Bayou Cove Project and Sterlington Project), each Equivalent Operating Hour
(with respect to the Rockford I Project and Rockford II Project) and each
Equivalent Start (with respect to the Big Cajun Project) shall be adjusted at
the beginning of each year by multiplying (i) the deposit for the prior year and
(ii) the composite price index (the "CPI"). The determination of the CPI is
based on an allocation of percentage weights for labor and materials pursuant to
the following formula:

                  CPI = [0.4 x (L(n)-L(i))/L(i)] + [0.6 x (M(n)-M(i))/M(i)] + 1]

         Where:

         L(n)  =  the Labor Index for the current year

         L(i)  =  the Labor Index for the prior year

         M(n)  =  the Material Index for the current year

         M(i)  =  the Material Index for the prior year

The "Labor Index" means the "Average Hourly Earnings of Production Workers,
Turbine and turbine generator set units, Series Id CEU3133361106" as published
by the Bureau of Labor Statistics, United States Department of Labor, rounded to
the nearest hundredth.

The "Material Index" means the "Producer Price Indexes, Series Id PCU3511# (N),
Turbines and turbine generator sets" as published by the Bureau of Labor
Statistics, United States Department of Labor, rounded to the nearest tenth.

For each operating year, defined as November of one year through October of the
following year, index values for September of the first year and the previous
year shall be used in the above calculations.

For example, the September 2003 value of the Average Hourly Earnings of
Production Workers, Turbine and turbine generator set units, Series Id
CEU3133361106 was 23.09, and the value of this index in September 2002 was
22.55. The September 2003 value of the Producer Price Indexes, Series Id
PCU3511# (N), Turbines and turbine generator sets was 153.5 (Preliminary) and
the September 20023 value of this index was 153.1. The CPI for the November 2003
- October 2004 operating year would therefore be:

     CPI = [0.4 x (23.09 -22.55)/22.55] + [0.6 x (153.5-153.1)/153.1] + 1]
           = 1.011146

To continue the example, the deposit for Bayou Cove for the November 2002 -
October 2003 period was $3,500.00 per Factored Start. The deposit for the
November 2003 - October 2004 period is $3,539.01, equal to the multiplicative
product of 1.011146 and $3,500.00.

                                      O-11

<PAGE>

The United States Department of Labor may revise any of the data referred to
above for a period of up to four (4) months after initial publication. If such a
revision occurs, the deposit shall be adjusted for such year in accordance with
such revised data.

If the United States Department of Labor, by footnote, appendix or any other
method, discontinues or revises any of the data referred to above (other than
benchmark adjustments) or revises the methodology for obtaining such data, a
substitute for the adjustment of the revised or discontinued data shall be
agreed to and used; provided, that such substitute shall result in substantially
the same adjustment, insofar as possible, as would have been achieved by
continuing the use of the original data had it not been revised or discontinued.

         conflict between the provisions of a Financing Document (exclusive of

         Appendix of a Financing Document shall mean such Exhibit, Schedule,
         Annex or Appendix as, amended, modified or supplemented from time to
         time in accordance with such Financing Document; provided that no

I.       The words "hereof," "herein" and "hereunder" and words of similar
         import when used in any document shall refer to such document as a
         whole and not to any particular provision of such document.

J.       The word "will" shall be construed to have the same meaning and effect
         as the word "shall."

K.       The use in this Agreement of the words "asset" and "property" shall be
         construed to have the same meaning and effect and to refer to any and
         all tangible and intangible assets and properties, including cash,
         securities, accounts and contract rights.

         and their respective counsel. Accordingly, the Financing Documents
         shall be deemed to be the product of all parties thereto, and no
         ambiguity shall be construed in favor of or against any Financing
         Party, any Equity Party, XLCA, the Swap Counterparty, the Trustee, the
         Collateral Agent or the Depositary Agent solely as a result of any such
         Person having drafted or proposed the ambiguous provision.
