                                    AGREEMENT

                  In consideration of the premises and for other good and
valuable consideration, the receipt and sufficiency of which are hereby
acknowledged and as an inducement to the issuance of the Series A Bonds and the
Policies and the execution of the Swap Agreement, the parties hereto agree as
follows:

                                   SECTION 1
                      Definitions; RULES OF INTERPRETATION

                  All capitalized terms used but not defined in this Agreement
shall have the meanings attributed to them in Annex A to the Common Agreement.
The rules of interpretation set forth in Annex A to the Common Agreement shall
apply hereto as though fully set forth herein.

                                   SECTION 2
                             NRG SUPPORT OBLIGATIONS

                  NRG Energy hereby agrees that, until the termination of this
Agreement as set forth in Section 10, it unconditionally and irrevocably
guarantees in favor of the Collateral Agent, for the benefit of the Secured
Parties, the prompt and complete payment when due of the Obligations to the
extent and under the circumstances, but only to the extent and under the
circumstances, described in Sections 2.1, 2.2 and 2.3 (including, without
limitation, all amounts which would have become due but for the operation of the
automatic stay under Section 362(a) of the Federal Bankruptcy Code, 11 U.S.C.
362(a)). This is a guarantee of payment and not of collection. In addition, NRG
Energy hereby agrees that it will undertake, perform and comply with the
obligations set forth in Sections 2.5, 2.6, 2.7, 2.8, 2.9 and 2.10. The
obligations of NRG Energy referred to in this first sentence of this paragraph
are referred to herein as the "NRG Guaranteed Obligations" and the obligations
of NRG Energy referred to in the immediately preceding sentence are referred to
herein as the "Other Undertakings" and, together with the NRG Guaranteed
Obligations, as the "NRG Support Obligations." Notwithstanding anything
contained herein or in any other Financing Document, NRG Energy's obligations
with respect to the Obligations are limited to the NRG Support Obligations.

                  Section 2.1 Performance Shortfall Payments. If on any Annual
Scheduled Payment Date, there exists (a) a Debt Service Shortfall and (b) a
Performance Shortfall, then NRG Energy agrees to pay, or to cause to be paid, in
Dollars, in immediately available funds on such Annual Scheduled Payment Date,
an amount equal to the lesser of (x) the Performance Shortfall with respect to
the immediately preceding Determination Period or (y) the Debt Service Shortfall
on such Annual Scheduled Payment Date (such payment, a "Performance Shortfall
Payment"). Any amount which is not paid when due pursuant to this Section 2.1
shall bear interest at the Late Payment Rate as in effect from time to time
until paid in full. Performance Shortfall Payments (plus any accrued interest
thereon) shall be paid to the Collateral Agent and applied on the applicable
Annual Scheduled Payment Date in accordance with the Depositary Agreement,
provided, however, that any Performance Shortfall Payment received by the
Collateral Agent following the Annual Scheduled Payment Date on which such
Performance Shortfall Payment was due in accordance with this Section 2.1 shall
be immediately paid by the

                                       2
<PAGE>

Collateral Agent (i) first, to XLCA in respect of the Accrued Insurer Loss
Amount (Swap), (ii) second, to XLCA in respect of the Accrued Insurer Loss
Amount (Bond), and (iii) third, to the Debt Payment Account.

                  Section 2.2 Experience Payments.

                  (a) [INTENTIONALLY OMITTED]

                  (b) On Annual Scheduled Payment Dates. If on any Annual
         Scheduled Payment Date a Debt Service Shortfall remains after giving
         effect to the application of any Performance Shortfall Payment due and
         payable on such Annual Scheduled Payment Date in accordance with
         Section 2.1, then NRG Energy agrees to pay, or to cause to be paid, in
         Dollars, in immediately available funds on such date, an amount equal
         to the lesser of (x) (i) the Total Experience Amount as of the
         immediately preceding Determination Date, as determined in accordance
         with Section 2.4 and as set forth in a certificate delivered by the
         Issuer to XLCA pursuant to Section 2.7(b) of the Common Agreement,
         minus (ii) the amounts applied pursuant to priorities Fifth and Sixth
         in Section 4.2.3 of the Depositary Agreement on such Annual Scheduled
         Payment Date and (y) the remaining Debt Service Shortfall on such
         Annual Scheduled Payment Date (such payment, an "Experience Payment").

                  (c) Payment in Connection with NRG Event of Default. On any
         date upon which there exists and is continuing an NRG Event of Default
         hereunder (other than an NRG Event of Default pursuant to Section
         13.1(a) hereof), NRG Energy may, in order to cure the Issuer Event of
         Default resulting therefrom as contemplated by Section 7.1(m)(iii) of
         the Common Agreement, at its sole option, pay, or to cause to be paid
         in Dollars, in immediately available funds on such date, an amount
         equal to (x) the Total Experience Amount as of the immediately
         preceding Determination Date as determined in accordance with Section
         2.4 and as set forth in a certificate delivered by the Issuer to XLCA
         pursuant to Section 2.7(b) of the Common Agreement minus (y) the
         aggregate of all Available Collateralized Experience Funds as of such
         date (such payment, an "Experience Cash Collateral Deposit").
         Experience Cash Collateral Deposits shall be paid by NRG Energy to the
         Collateral Agent, for immediate deposit into a segregated cash
         collateral account maintained by the Collateral Agent for the benefit
         of the Secured Parties as further described in Section 7.6. If at any
         time thereafter, NRG Energy is required to make a payment pursuant to
         clauses (b) or (d) of this Section 2.2, the Collateral Agent shall
         first apply Experience Cash Collateral Deposits toward such payment in
         accordance with priority Sixth in Section 4.2.3 of the Depositary
         Agreement. In order for such Experience Cash Collateral Deposit to
         continue to constitute a cure of any Issuer Event of Default resulting
         from a continuing NRG Event of Default (other that an NRG Event of
         Default pursuant to Section 13.1(a) hereof), NRG Energy shall be
         required to deposit additional funds into the applicable Cash
         Collateral Account such that the aggregate of all Available
         Collateralized Experience Funds equals the then current Total
         Experience Amount. If on any Scheduled Payment Date or LOC Substitution
         Date, the aggregate of all Available Collateralized Experience Funds
         exceeds the then current Total Experience Amount, the Collateral Agent
         shall direct the Depositary Agent to transfer an amount of immediately
         available funds in Dollars equal to such excess from

                                       3
<PAGE>

         such Cash Collateral Account to NRG Energy or any Affiliate thereof as
         directed by NRG Energy.

                  (d) Payment Upon Early Termination Date. On any date upon
         which the Controlling Party shall have accelerated the Obligations (or
         such Obligations shall have automatically become immediately due and
         payable following a Bankruptcy Event with respect to the Issuer)
         following the occurrence and continuation of an Issuer Event of Default
         in accordance with the Section 7.5(b) of the Common Agreement (an
         "Early Termination Date"), NRG Energy agrees to pay, or to cause to be
         paid in Dollars, in immediately available funds on such date, an amount
         equal to the lesser of (x) (i) the Total Experience Amount as of the
         immediately preceding Determination Date as determined in accordance
         with Section 2.4 and as set forth in a certificate delivered by the
         Issuer to XLCA pursuant to Section 2.7(b) of the Common Agreement minus
         (ii) the aggregate of all Available Collateralized Experience Funds as
         of such date and (y) the then outstanding Obligations as so accelerated
         (such payment, an "Experience Termination Payment"). The Collateral
         Agent shall apply Experience Termination Payments as directed by the
         Controlling Party.

                  (e) General Terms. Any amount which is not paid when due
         pursuant to this Section 2.2 shall bear interest at the Late Payment
         Rate as in effect from time to time until paid in full. Experience
         Payments (plus any accrued interest thereon) shall be paid to the
         Collateral Agent and applied on the applicable Annual Scheduled Payment
         Date in accordance with the Depositary Agreement; provided, however,
         that any Experience Payment received by the Collateral Agent following
         the Annual Scheduled Payment Date on which such Experience Payment was
         due in accordance with this Section 2.2 shall be immediately paid by
         the Collateral Agent (i) first, to XLCA in respect of the Accrued
         Insurer Loss Amount (Swap), (ii) second, to XLCA in respect of the
         Accrued Insurer Loss Amount (Bond), and (iii) third, to the Debt
         Payment Account.

                  Section 2.3 Deductible Payments.

                  (a) On Annual Scheduled Payment Dates. If on any Annual
         Scheduled Payment Date a Debt Service Shortfall remains after giving
         effect to the application of (a) any Performance Shortfall Payment due
         and payable on such Annual Scheduled Payment Date in accordance with
         Section 2.1, (b) the amounts applied pursuant to priorities Fifth and
         Sixth in Section 4.2.3 of the Depositary Agreement and (c) any
         Experience Payment due and payable on such Annual Scheduled Payment
         Date in accordance with Section 2.2, then NRG Energy agrees to pay, or
         to cause to be paid, in Dollars, in immediately available funds on such
         Annual Scheduled Payment Date, an amount equal to the lesser of (x) the
         remaining Debt Service Shortfall and (y) (i) the Deductible Limit minus
         (ii) the aggregate of (A) all Deductible Payments previously made
         hereunder, for which NRG Energy has not yet been reimbursed pursuant to
         Section 4.1.2 of the Depositary Agreement (or otherwise), and (B) the
         amounts applied pursuant to priorities Eighth and Ninth in Section
         4.2.3 of the Depositary Agreement on such Annual Scheduled Payment
         Date. Deductible Payments made pursuant to this Section 2.3(a) (plus
         any accrued interest thereon) shall be paid to the Collateral Agent and
         applied on such applicable Annual Scheduled Payment Date in accordance
         with the Depositary Agreement; provided, however, that any Deductible
         Payment received by the Collateral Agent following the Annual Scheduled
         Payment

                                       4
<PAGE>

         Date on which such Deductible Payment was due under this Section 2.3
         shall be immediately paid by the Collateral Agent (i) first, to XLCA in
         respect of the Accrued Insurer Loss Amount (Swap), (ii) second, to XLCA
         in respect of the Accrued Insurer Loss Amount (Bond), and (iii) third,
         to the Debt Payment Account.

                  (b) Payment in Connection with NRG Event of Default. On any
         date upon which there exists and is continuing an NRG Event of Default
         hereunder (other than an NRG Event of Default pursuant to Section
         13.1(a) hereof), NRG Energy may, in order to cure the Issuer Event of
         Default resulting therefrom as contemplated by Section 7.1(m)(iii) of
         the Common Agreement, at its sole option, pay, or to cause to be paid
         in Dollars, in immediately available funds on such date, an amount
         equal to (x) the Deductible Limit, minus (y) the aggregate of all
         Deductible Payments previously made hereunder, for which NRG Energy has
         not yet been reimbursed pursuant to Section 4.1.2 of the Depositary
         Agreement (or otherwise), minus (z) the aggregate of all Available
         Collateralized Deductible Funds as of such date (such payment, an
         "Deductible Cash Collateral Deposit"). Deductible Cash Collateral
         Deposits shall be paid by NRG Energy to the Collateral Agent, for
         immediate deposit into a segregated cash collateral account maintained
         by the Collateral Agent for the benefit of the Secured Parties as
         further described in Section 7.6. If at any time thereafter NRG Energy
         is required to make a payment pursuant to clauses (a) or (c) of this
         Section 2.3, the Collateral Agent shall first apply Deductible Cash
         Collateral Deposits toward such payment in accordance with priority
         Ninth in Section 4.2.3 of the Depositary Agreement. If on any Scheduled
         Payment Date or LOC Substitution Date, the aggregate of all Available
         Collateralized Deductible Funds exceeds the amount of Deductible Cash
         Collateral Deposits calculated in accordance with clauses (x), (y) and
         (z) above as of such date, the Collateral Agent shall direct the
         Depositary Agent to transfer an amount of immediately available funds
         in Dollars equal to such excess from the applicable Cash Collateral
         Account to NRG Energy or any Affiliate thereof as directed by NRG
         Energy.

                  (c) Payment Upon Early Termination Date. On any Early
         Termination Date, NRG Energy agrees to pay, or to cause to be paid in
         Dollars, in immediately available funds on such date, an amount equal
         to the lesser of (A) (x) the Deductible Limit minus (y) the sum of (i)
         all Deductible Payments previously made hereunder for which NRG Energy
         has not yet been reimbursed pursuant to Section 4.1.2 of the Depositary
         Agreement (or otherwise), and (ii) the aggregate of all Available
         Collateralized Deductible Funds as of such date, and (B) (x)
         $32,500,000 (or the then Outstanding (as defined in the Indenture)
         principal amount of the Series A Bonds, if less) plus (y) all interest
         on the Series A Bonds accrued through such Early Termination Date and
         not yet paid (calculated giving effect to the Swap Agreement) (such
         payment, a "Deductible Termination Payment"). The Collateral Agent
         shall apply Deductible Termination Payments as directed by the
         Controlling Party.

                  (d) General Terms. Any amount which is not paid when due
         pursuant to this Section 2.3 shall bear interest at the Late Payment
         Rate as in effect from time to time until paid in full.

         (Peaker Sale/Project Event of Default), the Total Experience Amount

                  Until this Agreement is terminated in accordance with Section
10 hereof, NRG Energy covenants and agrees with the Collateral Agent, for the
benefit of the Secured Parties, as follows:

                  Section 4.1 Corporate Existence; Business; Asset Sales. NRG
Energy shall preserve and maintain (i) its legal existence and form and (ii) all
of its rights, privileges and franchises, if any, necessary to perform its
obligations under this Agreement, provided, however, that NRG Energy may merge
or consolidate with or into, or may sell, convey, transfer or lease its
properties and assets substantially as an entirety to any Person so long as (A)
NRG Energy is the surviving or continuing corporation, or the surviving or
continuing corporation or corporation that acquires by sale, conveyance,

Default shall have occurred and be continuing. Except as permitted in the
preceding proviso, and other than assets required to be sold to conform with
Legal Requirements, NRG Energy shall not sell or otherwise dispose of any assets
(other than short-term, readily marketable investments purchased for cash
management purposes with funds not representing the proceeds of other asset
sales) if on a pro-forma basis, the aggregate net book value of all such sales
during the most recent 12-month period would exceed 10% of NRG Energy's
Consolidated Net Tangible Assets computed as of the end of the most recent
quarter preceding such sale; provided, however, that any such sales shall be
disregarded for purposes of this 10% limitation if the proceeds are invested in
assets in similar or related lines of business and, provided, further, that NRG
Energy may sell or otherwise dispose of assets in excess of such 10% limitation
if the proceeds from such sales or dispositions, which are not reinvested as
provided above, are retained as cash or cash equivalents or applied to reduce or
retire Debt of NRG Energy ranking senior to or equal with the NRG Support
Obligations. For purposes of this Section 4.1, "Consolidated Net Tangible
Assets" shall mean, as of the date of any determination thereof, with respect to
NRG Energy, the total amount of all of NRG Energy's assets determined on a
consolidated basis in accordance with GAAP as of such date less the sum of (a)
NRG Energy's consolidated current liabilities determined in accordance with GAAP
and (b) NRG Energy's assets properly classified as intangible assets in
accordance with GAAP.

                  Section 4.2 Compliance with Legal Requirements. NRG Energy
shall comply in all material respects with all Legal Requirements binding on it,
except where failure to do so could not reasonably be expected to have an NRG
Energy Material Adverse Effect.

taxes, rates, assessments, fees and governmental charges upon or against it or
against its properties, in each case before the same becomes delinquent and
before penalties accrue thereon, unless and to the extent that the same is being
contested in good faith by appropriate proceedings and reserves in conformity
with GAAP have been provided therefore on the books of NRG Energy.

                  Section 4.4 Insurance. NRG Energy shall insure, and keep
insured with good and responsible insurance companies, all insurable property
owned by it of a character usually insured by companies similarly situated and
operating like property. To the extent usually insured (subject to self-insured
retentions) by companies similarly situated and conducting similar businesses,
NRG Energy will also insure employers' and public and product liability risks
with good and responsible insurance companies. NRG Energy shall not, however, be
required to maintain terrorism insurance for its properties.

                  Section 4.5 Ranking. NRG Energy shall cause its obligations
hereunder to at all times rank at least pari passu with all other senior
unsecured obligations of NRG Energy.

                  (d) NRG Energy shall promptly, upon acquiring notice or giving
notice, as the case may be, or obtaining knowledge thereof, give written notice

                                    WAIVERS

                  NRG Energy hereby waives and relinquishes all rights and
remedies accorded by applicable Legal Requirements to sureties or guarantors and
agrees not to assert or take

                                       13

advantage of any such rights or remedies, including (a) any right to require the
Collateral Agent or any other Secured Party to proceed against any 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 NRG Energy (except to the extent
expressly set forth herein), (b) any defense that may arise by reason of the
incapacity, lack of power or authority, death, 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, 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 foregoing 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 for or in connection with any of the
Obligations, (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 NRG Energy, the right of NRG Energy to proceed
against the Issuer, any Project Company or any other Person for reimbursement,
or both, (e) any defense based on any offset against any amounts which may be
owed by any Person to NRG Energy for any reason whatsoever, (f) any defense
based on any act, failure to act, delay or omission whatsoever on the part of
the Issuer or any Project Company or the failure by the Issuer or any Project
Company to do any act or thing or to observe or perform any covenant, condition
or agreement to be observed or performed by it under the Financing Documents,
(g) any defense based upon any statute or rule of law which provides that the
obligation of a surety must be neither larger in amount nor in other respects
more burdensome than that of the principal, (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 NRG Energy any facts
that 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 any other Secured Party has reason to believe that any such facts
materially increase the risk beyond that which NRG Energy intends to assume, or
have reason to believe that such facts are unknown to NRG Energy, or have a
reasonable opportunity to communicate such facts to NRG Energy, since NRG Energy
acknowledges that NRG Energy 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 of any obligations and
liabilities hereby guaranteed, (j) any defense based on any change in the time,
manner or place of any payment 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.

                                   SECTION 7
                               SPECIFIC PROVISIONS

                  Section 7.1 Reinstatement. This Agreement and the obligations
of NRG Energy hereunder shall automatically be reinstated if and to the extent
that for any reason any payment made pursuant to this Agreement is rescinded or
otherwise restored to NRG Energy, whether as a result of any proceedings in
bankruptcy or reorganization or otherwise with respect to Issuer or any other
Person or as a result of any settlement or compromise with any Person (including
NRG Energy) in respect of such payment, and NRG Energy 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.

                  Section 7.2 Specific Performance. NRG Energy hereby
irrevocably waives, to the extent it may do so under applicable Legal
Requirements, any defense based on the adequacy of a remedy at law that may be
asserted as a bar to the remedy of specific performance in any action brought
against NRG Energy for specific performance of this Agreement by the Issuer or
any successor or assign thereof (including the Collateral Agent) or for their
benefit by a receiver, custodian or trustee appointed for the Issuer or in
respect of all or a substantial part of its assets, under the bankruptcy or
insolvency laws of any jurisdiction to which the Issuer or its assets are
subject.

                  Section 7.3 Bankruptcy Code Waiver. NRG Energy hereby
irrevocably waives, to the extent it may do so under applicable Legal
Requirements, any protection to which it may be entitled under Sections
365(c)(1), 365(c)(2) and 365(e)(2) of the Bankruptcy Law or equivalent
provisions of the laws or regulations of any other jurisdiction with respect to
any proceedings, or any successor provision of law of similar import, in the
event of any Bankruptcy Event of it, the Issuer or any Project Company.
Specifically, in the event that the trustee (or similar official) in a
Bankruptcy Event of NRG Energy, the Issuer or any Project Company or the
debtor-in-possession takes any action, NRG Energy shall not assert any defense,
claim or counterclaim denying liability hereunder on the basis that this
Agreement is an executory contract or a "financial accommodation" that cannot be
assumed, assigned or enforced or on any other theory directly or indirectly
based on Section 365(c)(1), 365(c)(2) or 365(e)(2) of the Bankruptcy Law, or
equivalent provisions of the laws or regulations of any other jurisdiction with
respect to any proceedings or any successor provision of law of similar import.
If a Bankruptcy Event of NRG Energy, the Issuer or any Project Company shall
occur, NRG Energy agrees, after the occurrence of such Bankruptcy Event, to
reconfirm in writing, to the extent permitted by applicable Legal Requirements,
its pre-petition waiver of any protection to which it may be entitled under
Sections 365(c)(1), 365(c)(2) and 365(e)(2) of the Bankruptcy Law or equivalent
provisions of the laws or regulations of any other jurisdiction with respect to
proceedings and, to give effect to such waiver, NRG Energy consents to the
assumption and enforcement of each provision of this Agreement by the
debtor-in-possession or the Issuer's or any Project Company's trustee in
bankruptcy, as the case may be.

                  Section 7.4 No Commencement of Bankruptcy Proceedings. So long
as the Financing Documents remain in effect, NRG Energy shall not, without the
prior written consent of the Controlling Party, commence, or join with any other
Person in commencing, any bankruptcy, reorganization, or insolvency proceeding
against the Issuer or any Project Company.

                                       15
<PAGE>

The obligations of NRG Energy under this Agreement shall not be altered, limited
or affected by any proceeding, voluntary or involuntary, involving the
bankruptcy, reorganization, insolvency, receivership, liquidation or arrangement
of any the Issuer or any Project Company, or by any defense which the Issuer or
any Project Company may have by reason of any order, decree or decision of any
court or administrative body resulting from any such proceeding.

                  Section 7.5 Set-Off. In addition to any rights now or
hereafter granted under applicable Legal Requirements or otherwise, and not by
way of limitation of any such rights, upon the failure of NRG Energy to make any
payments as required by Section 2 hereunder, the Collateral Agent is hereby
authorized at any time or from time to time, without presentment, demand,
protest or other notice of any kind to NRG Energy or to any other Person, any
such notice being hereby expressly waived, to set-off and to appropriate and
apply any and all deposits (general or special) and any other indebtedness at
any time held or owing by any Secured Party (including by branches and agencies
of each of the Secured Parties wherever located) to or for the credit or the
account of NRG Energy, against and on account of the obligations of NRG Energy
then due under this Agreement, irrespective of whether or not the Collateral
Agent shall have made any demand hereunder.

                  Section 7.6 Cash Collateral Accounts

                  (a) All amounts required to be deposited as cash collateral
with the Collateral Agent pursuant to Section 2.2(c) and Section 2.3(b) shall be
deposited in separate cash collateral accounts (such accounts, and any
replacement or supplemental account into which any such cash collateral may at
any time be deposited, collectively, the "Cash Collateral Accounts") established
by NRG Energy with the Collateral Agent and under the dominion and control of
the Collateral Agent, to be held or applied, or released for application, as
provided in this Section 7.6. NRG Energy hereby grants to the Collateral Agent,
for the benefit of Secured Parties, as security for the payment and performance
of the NRG Guaranteed Obligations, a security interest in and lien on (i) the
Cash Collateral Accounts, (ii) all amounts now or at any time on deposit
therein, (iii) all investment property or other financial assets from time to
time credited thereto, and (iv) all proceeds of any of the foregoing, in
whatever form. In connection with the making of the initial deposit in any Cash
Collateral Account NRG Energy shall be required to (a) execute such
documentation as may be necessary, or that is reasonably requested by the
Collateral Agent, in order to grant to the Collateral Agent, for the benefit of
the Secured Parties, a first priority perfected security interest in the Cash
Collateral Accounts (subject to NRG Permitted Liens), including without
limitation an account control agreement containing control provisions
substantially similar to those contained in the Depositary Agreement and (b)
deliver an opinion of counsel with respect to the Cash Collateral Accounts
substantially similar to the opinion given with respect to the Accounts on the
Closing Date. Upon the earlier to occur of (i) termination of this Agreement in
accordance with Section 10 or (ii) the cure of the NRG Event of Default which
triggered the making of a Cash Collateral Deposit, the Collateral Agent shall
take, at NRG Energy's expense, such actions as NRG Energy may reasonably request
to effect the release of such Cash Collateral Deposit and the security interest
and lien granted pursuant to this clause (a), provided, however, that in the
case of clause (ii) of this sentence, at the time of such proposed release no
other NRG Event of Default shall have occurred and be continuing.

                                       16
<PAGE>

                  (b) Interest and other payments and distributions made on or
with respect to the cash collateral held by the Collateral Agent pursuant to
clause (a) of this Section 7.6 shall be for the account of NRG Energy and shall
constitute cash collateral to be held by the Collateral Agent or returned to NRG
Energy in accordance with clause (a) of this Section 7.6 or in accordance with
Section 2.2(c) or 2.3(b).

                  (c) NRG Energy may at any time replace cash on deposit in any
Cash Collateral Account with an Acceptable Letter of Credit. Such Acceptable
Letter of Credit shall be administered in accordance with Section 5.2 of the
Depositary Agreement.

                  (d) Cash held in any Cash Collateral Account shall be invested
and reinvested in Permitted Investments (which Permitted Investments shall be
only those described in clauses (a), (b), (e), (f) or (g) of the definition
thereof) by the Collateral Agent, which shall make such Permitted Investments
(a) when no Issuer Event of Default has occurred and is continuing, at the
written direction of NRG Energy (provided that in the absence of any contrary
written direction of NRG Energy with respect to any cash held in any Cash
Collateral Account, NRG Energy hereby directs the Collateral Agent to invest
such cash in Permitted Investments of the type specified in clause (a) of the
definition thereof (which direction is deemed to be a written investment
instruction for purposes of the following sentence)), and (b) when an Issuer
Event of Default has occurred and is continuing, in Permitted Investments of the
type specified in clause (a) of the definition thereof. The Collateral Agent
shall have no obligation to invest or reinvest any amounts held hereunder in the
absence of written investment instructions, and in no event shall the Collateral
Agent be liable for the selection of Permitted Investments or for investment
losses, if any, incurred thereon. Any and all commissions, broker fees or other
charges, penalties, fees or expenses incurred in connection with the investment
in, or liquidation of, any Permitted Investment shall be solely for the account
of NRG Energy, and shall be debited against the cash balance in the applicable
Cash Collateral Account.

                  (e) The Collateral Agent shall sell or liquidate all or any
portion of the Permitted Investments held in any Cash Collateral Account at any
time the proceeds thereof are required to make any disbursement from such Cash
Collateral Account in accordance with the terms of this Agreement. Any such sale
or liquidation shall be in the order of maturity of the applicable Permitted
Investments, with Permitted Investments closest to maturity being sold or
liquidated first. In no event shall the Collateral Agent be liable for any
losses incurred as a result of the liquidation of any Permitted Investment prior
to its stated maturity (including, without limitation, any early withdrawal or
liquidation penalty) or the failure of any Person to provide timely written
investment instructions.

                                   SECTION 8
                             DEDUCTIONS/WITHHOLDING

                  All sums, if any, payable by NRG Energy hereunder shall be
paid in full, free of any deductions or withholdings for any and all Taxes
imposed by any governmental authority of any jurisdiction through which payment
is made. In the event that NRG Energy is prohibited by law from making any such
payments hereunder free of such deductions or withholdings, then NRG Energy
shall pay such additional amount as may be necessary in order that the actual
amount received after such deduction or withholding shall equal the full amount
stated to be

                                       17
<PAGE>

payable hereunder. NRG Energy shall pay directly to all appropriate taxing
authorities any and all Taxes, and all liabilities with respect to such Taxes
imposed by law or by any taxing authority on or with regard to any payment
required to be made by NRG Energy hereunder. Notwithstanding the foregoing, if a
payment due from NRG Energy hereunder relates to a payment which, if directly
made by the Issuer or other primary obligor, would have been subject to
deduction or withholding of Taxes without any gross-up obligation (or an
obligation to pay an additional amount) on the part of the Issuer or other
primary obligor, NRG Energy shall not be required to pay additional amounts
under this Section 8.

                                   SECTION 9
                                    NOTICES

                  Any notice or other communication hereunder shall be given in
writing and shall be personally delivered or sent by registered or certified
mail (postage prepaid, return receipt requested), by overnight courier or by
facsimile transmission with confirmation by overnight courier, and shall be
deemed to have been duly given or made when received by the intended recipient

                                   TERMINATION

                  This Agreement shall terminate upon the earlier of (a) payment
in full of the Obligations or (b) the occurrence of an Early Termination Date,
provided that NRG Energy's obligation to pay (i) the Experience Termination
Payment, (ii) the Deductible Termination

                                       18

Payment and (iii) any amounts due and payable hereunder accruing prior to such

the proviso in the preceding sentence, the Other Undertakings for a Project
Company and its Project shall terminate upon the earlier of (a) the occurrence
of a Project Release Event with respect to such Project Company and (b) the
occurrence of an Early Termination Date. The Collateral Agent agrees to execute
such documents and take such other actions as reasonably requested by, and at
the expense of, NRG Energy in order to effect and evidence any such termination.

                                   SECTION 11
                             SUCCESSORS AND ASSIGNS

                  This Agreement shall be binding upon and inure to the benefit
of the parties hereto and their respective successors and permitted assigns.
This Agreement may not be assigned by NRG Energy except with the consent of the
Collateral Agent (in accordance with Section 9.2 of the Common Agreement) unless
assigned, in part, in connection with a Permitted Change of Control in

(x) is rated at least A3 by Moody's and A- by S&P or (y) is rated at least Baa2
by Moody's and BBB by S&P and has provided cash, Acceptable Letters of Credit or
other credit support acceptable to the Controlling Party in its sole discretion

                                   SECTION 12
                                    AMENDMENT

                  No amendment or waiver of any provision of this Agreement nor
any consent to any departure by NRG Energy herefrom shall in any event be
effective unless the same shall be in writing and signed by NRG Energy and the
Collateral Agent (in accordance with Section 9.2 of the Common Agreement), and
then such waiver or consent shall be effective only in the specific instance and
for the specific purpose for which given.

                                   SECTION 13
                         EVENTS OF DEFAULT AND REMEDIES

                  Section 13.1 Events of Default. The occurrence of any of the
following events shall constitute an event of default hereunder (an "NRG Event
of Default"):

                  (a) NRG Energy shall fail to make any payment as and when due
under this Agreement;

                  (b) Any representation or warranty by NRG Energy set forth in
this Agreement or in any document entered into in connection herewith in favor
of or for the benefit of any Secured Party or in any certificate, financial
statement or other document delivered in connection herewith for the benefit of
any Secured Party shall prove to have been incorrect in

                                       19
<PAGE>

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 NRG Energy 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 NRG Energy becomes aware thereof or NRG Energy first received a
notice from or on behalf of the Controlling Party specifying such material
inaccuracy and requiring that facts or events underlying such incorrect
representation or warranty be changed so as to correct such incorrect
representation or warranty in all material respects.

                  (c) NRG Energy shall default in the due observance or
performance of any agreement contained in Section 4.1 (excluding Section 4.1(ii)
but including the proviso thereto);

                  (d) NRG Energy shall default in the due observance or
performance of any covenant, condition or agreement contained in this Agreement
(other than specified in Section 13.1(c) above) and such default shall continue
unremedied for a period of 30 days after notice thereof from the Collateral
Agent, provided, however, if (i) such failure does not consist of a failure to
pay money and cannot be cured within such 30 day period, (ii) such failure is
susceptible of cure within 90 days, (iii) NRG Energy is proceeding with
diligence and in good faith to cure such failure, (iv) the existence of such
failure has not had and cannot after considering the nature of the cure be
reasonably expected to have an NRG Energy Material Adverse Effect, and (v) the
Collateral Agent shall have received an officer's certificate signed by a
Responsible Officer of NRG Energy to the effect of clauses (i), (ii), (iii) and
(iv) above and stating what action NRG Energy is taking to cure such failure,
then such 30 day cure period shall be extended to such date, not to exceed a
total of 90 days, as shall be necessary for NRG Energy diligently to cure such
failure; provided, further, that in the case of a default in the due observance
or performance of Section 2.7, the applicable cure period shall not exceed a
total of 60 days;

                  (e) NRG Energy 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 NRG Energy (other than amounts
under the Financing Documents) and such defaulted amount, together with any
other principal, interest or other amount due and unpaid on any Debt for
Borrowed Money of NRG Energy (other than amounts under the Financing Documents)
equals or exceeds $50,000,000, or in the performance of any Specified Financial
Covenant; or (ii) in the payment of any amount then due or performance of any
obligation then required (other than a Specified Financial Covenant) under any
agreement evidencing Debt of NRG Energy (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 NRG
Energy then so accelerated (other than the obligations under the Financing
Documents) equals or exceeds $50,000,000, provided, that it shall not constitute
an NRG Event of Default as set forth in clause (i) with respect to a breach of
any Specified Financial Covenant if, and for so long as, NRG Energy provides an
officer's certificate from a responsible officer stating that either NRG Energy
and the holder(s) of the relevant obligation(s) under the relevant agreement(s)
in which such Specified Financial Covenant appears are, and continue to be, in

                                       20
<PAGE>

active discussions with respect to the waiver of such default (such Officer's
Certificate to be renewed every 10 Business Days) or that a default no longer
exists under such relevant agreements as a result of a breach of any Specified
Financial Covenant;

                  (f) NRG Energy shall be subject to a Bankruptcy Event;

                  (g) One or more final judgments for the payment of money (if
such payments are not fully covered by insurance) in excess of $50,000,000 in
the aggregate shall be rendered against NRG Energy, and NRG Energy shall fail to
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 NRG Event of Default under this Section 13.1(g) if and
for so long as either (i) (A) 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 (B) such insurer has been notified of, and has not
disputed the claim made for payment of, the amount of such judgment, or (ii)
such judgment if left unstayed could not reasonably be executed to have an NRG
Material Adverse Effect; or

                  (h) 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 NRG Material Adverse Effect.

                  Section 13.2 Remedies. Upon the occurrence of an NRG Event of
Default, the Collateral Agent (acting at the direction of the Controlling Party)
shall (a) have the right to declare all obligations then due and payable under
this Agreement to be immediately due and payable and require NRG Energy to
immediately pay to the Collateral Agent in immediately available funds an amount
equal to the aggregate amount of the obligations so accelerated (provided that

such obligations shall be automatically accelerated), and (b) have all the
rights and remedies available to it at law or in equity or by statute in respect

or reserved to any party is intended to be exclusive of any other available
remedy or remedies, but each and every such remedy shall be cumulative and shall
be in addition to every other remedy given under this Agreement or now or
hereafter existing at law or in equity or by statute. In order to entitle any
party to exercise any remedy reserved to it in this Agreement, it shall not be
necessary to give any notice, other than such notice as may be expressly
required by this Agreement. No failure or delay on the part of any party in
exercising any right, power or privilege hereunder and no course of dealing
between NRG Energy and any Secured Party shall operate as a waiver thereof; nor
shall any single or

the Southern District of New York, (ii) consents to the service of process

proceeding by mailing copies thereof by registered United States mail, postage
prepaid, to the address specified pursuant to Section 9 hereof, and (iii) to the

Corporation Service Company, with offices on the date hereof at 1177 Avenue of
the Americas, 17th Floor, New York, New York 10036-2721, as its designee,
appointee and agent with respect to any action or proceeding in New York to
receive for and on its behalf service of any and all legal process, summons,
notices and documents which may be served in any such action or proceeding and
agrees that the failure of such agent to give any advice of any such service of
process to such person shall not impair or affect the validity of such service
or of any judgment based thereon. If for any reason such designee, appointee and
agent shall cease to be available to act as such, NRG Energy agrees to designate
a new designee, appointee and agent in New York City on the terms and for the
purposes of this provision.

                                   SECTION 17

                                   Litigation

None, other than the following:

(1)      Those described in NRG Energy's Annual Report on Form 10-K for the year
         ended December 31, 2001, NRG Energy's Quarterly Report on Form 10-Q for
         the quarter ended March 31, 2002 and/or any Current Report on Form 8-K
         of NRG Energy filed on or prior to the Closing Date;

(2)      On May 24, 2002, a class action was instituted in San Francisco County
         Superior Court in California against a group of generators, including
         NRG Energy's affiliates Cabrillo Power I, LLC, El Segundo Power, LLC,
         and Long Beach Generation, LLC (Bronco Don Holdings, LLP v. Duke Energy
         Trading and Marketing, LLC, et al.). This case essentially asserts the
         same claims set forth in the previously reported T&E Pastorino Nursery
         action, i.e., violation of California Business & Professions Code
         Section 17200 based on defendants' alleged withholding of electricity
         from the market to artificially create a shortage, violation of
         ancillary services agreements by various defendants, and market
         manipulation by defendants by means of their execution with the
         California Department of Water Resources of long term contracts,
         allegedly at supracompetitive rates. Similarly, in mid-May 2002, a
         class action was instituted in San Joaquin County Superior Court in
         California against energy suppliers, including the same NRG Energy
         affiliates (RDJ Farms, Inc., and Brittalia Ventures v. Allegheny Energy
         Supply Company, LLC et al.). This case asserts violations of California
         Business & Professions Code Sections 16720 and 17200 again based on
         alleged exercise of market power by defendants, and market manipulation
         by defendants by means of their execution with the California
         Department of Water Resources of long term contracts, allegedly at
         supracompetitive rates. There can be no assurance as to the outcome of
         these claims.

(3)      In early June 2002, a class action was instituted in San Francisco
         County Superior Court in California against a group of generators and
         traders, including NRG Energy, on behalf of a putative class of rate
         payers in the State of Washington (Donna G. Hansen v. Dynegy Power
         Marketing, Inc., et al.). This action seeks injunctive and equitable
         relief, including restitution and disgorgement with respect to monetary
         injuries, for violations of California Business & Professions Code
         Sections 16720 and 17200 for alleged combining by the defendants to
         restrain the amount of energy available for sale through the California
         PX and ISO energy markets, conspiring to illegally obtain and trade
         information relating to energy supply, pricing and demand, and
         combining to raise the "market clearing bid" for electric energy on the
         PX wholesale markets, all of which allegedly raised prices for
         electricity to retail and wholesale consumers in the Pacific Northwest.
         There can be no assurance as to the outcome of these claims.<PAGE>

                  the participant and/or qualified beneficiaries.

                  In the event the COBRA premium shall change for all employees

Article 5. Excise Tax

         5.1 Excise Tax Equalization Payment. If the Participant becomes
entitled to severance benefits or any other payment or benefit under this
Agreement, or under any other agreement or plans of the Company (in the
aggregate, the "Total Payments"), and any of the Total Payments will be subject
to the tax (the "Excise Tax") imposed by Section 4999 of the Code (or any
similar tax that may hereafter be imposed), the Company shall pay to the
Participant in cash an additional amount (the "Gross-Up Payment") such that the
net amount retained by the Participant after deduction of any Excise Tax upon
the Total Payments and any federal, state and local income tax and Excise Tax
upon the Gross-Up Payment provided for by this Section 5.1 (including FICA and
FUTA), shall be equal to the Total Payments. Such payment shall be made by the
Company to the Participant as soon as practicable following the effective date
of termination, but in no event beyond forty-five (45) days from such date.

         5.2 Tax Computation. For purposes of determining whether any of the
Total Payments will be subject to the Excise Tax and the amounts of such Excise
Tax:

              (a) Any other payments or benefits received or to be received
                  by the Participant in connection with a Restructuring Bonus or
                  the Participant's termination of employment (whether pursuant
                  to the terms of this Agreement or any other plan, arrangement,
                  or agreement with the Company, or with any person (which shall
                  have the meaning set forth in Section 3(a)(9) of the
                  Securities Exchange Act of 1934, including a "group" as
                  defined in Section 13(d) therein) whose actions result in a
                  Change in Control of the Company or any person affiliated with
                  the Company or such persons) shall be treated as "parachute
                  payments" within the meaning of Section 280G(b)(l) of the Code
                  and shall be treated as subject to the Excise Tax, unless in
                  the opinion of tax counsel as supported by the Company's
                  independent auditors and acceptable to the Participant, such
                  other payments or benefits (in whole or in part) do not, or
                  unless such excess parachute payments (in whole or in part)
                  represent reasonable compensation for services actually
                  rendered within the meaning of Section 280G(b)(4) of the Code
                  in excess

                                        7
<PAGE>

                  of the base amount within the meaning of Section 280G(b)(3) of
                  the Code, or are otherwise not subject to the Excise Tax;

              (b) The amount of the Total Payments which shall be treated as
                  subject to the Excise Tax shall be equal to the lesser of: (i)
                  the total amount of the Total Payments; or (ii) the amount of
                  excess parachute payments within the meaning of Section
                  280G(b)(3) (after applying clause (a) above); and

              (c) The value of any non-cash benefits or any deferred payment or
                  benefit shall be determined by the Company's independent
                  auditors in accordance with the principles of Section 280G(d)
                  (3) and (4) of the Code.

         For purposes of determining the amount of the Gross-Up Payment, the
Participant shall deemed to pay federal income taxes at the highest marginal
rate of federal income taxation in the calendar year in which the Gross-Up
Payment is to be made, and state and local income taxes at the highest marginal
rate of taxation in the state and locality of the Participant's residence on
the effective date of termination, net of the maximum reduction in federal
income taxes which could be obtained from deduction of such state and local
taxes.

         5.3 Subsequent Recalculation. If the Internal Revenue Service adjusts
the computation of the Company under Section 5.2 herein so that the Participant
did not receive the greatest net benefit, the Company shall reimburse the
Participant for the full amount necessary to make the Participant whole, plus a
market rate of interest, as determined by the Committee.

Article 6. Outplacement Assistance

         Following a termination of employment in which Severance Benefits are
payable hereunder, the Participant shall be reimbursed by the Company for the
costs of all outplacement services obtained by the Participant within the two
(2) year period after the Effective Date of Termination; provided, however, that
the total reimbursement shall be limited to $15,000.

Article 7. The Company's Payment Obligation

         7.1 Payment Obligations Absolute. Except as provided herein, the
Company's obligation to make the payments and the arrangements provided for
herein shall be absolute and unconditional, and shall not be affected by any
circumstances, including, without limitation, any offset, counterclaim,
recoupment, defense, or other right which the Company may have against the
Participant or anyone else. All amounts payable by the Company hereunder shall
be paid without notice or demand. Except as provided herein, each and every
payment made hereunder by the Company shall be final, and the Company shall not
seek to recover all or any part of such payment from the Participant or from
whomever may be entitled thereto. Notwithstanding the foregoing, the Company
reserves the right to conduct an independent investigation for the sole purpose
of determining whether "Cause" exists that would negate a payment hereunder.
Until the conclusion of such investigation (which shall be conducted
expeditiously) the Company reserves the right to suspend payment of benefits or
alternatively, to condition any benefits on the results of such investigation.
For purposes of this section, "expeditiously" shall be defined as

                                        8
<PAGE>

a reasonable period of time not to exceed six (6) months. Participant shall be
notified within thirty (30) days of the conclusion of the investigation.

         The Participant shall not be obligated to seek other employment in
mitigation of the amounts payable or arrangement made under any provision of
this Agreement, and the obtaining of any such other employment shall in no event
affect any reduction of the Company's obligations to make the payments and
arrangements required to be made under this Agreement.

         7.2 Contractual Rights to Benefits. This Agreement establishes and
vests in the Participant a contractual right to the benefits to which he is
entitled hereunder. However, nothing herein contained shall required or be
deemed to require, or prohibit or be deemed to prohibit, the Company to
segregate, earmark, or otherwise set aside any funds or other assets, in trust
or otherwise, to provide for any payments to be made or required hereunder.

         7.3 Bankruptcy Court Approval

         Participant acknowledges that an involuntary petition under the
Bankruptcy Code has been filed against the Company in the United States
Bankruptcy Court for the District of Minnesota (the "Bankruptcy Court"). If an
order for relief under the Bankruptcy Code is entered against the Company in the
Bankruptcy Court or any other bankruptcy court, or if the Company commences a
voluntary case under Chapter 11 of the Bankruptcy Code, the Company shall
promptly move the applicable bankruptcy court for an order authorizing the
assumption of this Agreement under section 365 of the Bankruptcy Code or such
other relief as appropriate to ensure compliance with this Agreement by the
Company and the receipt by the Participant of the rights granted hereunder.

         7.4 Xcel Guaranty.

         Xcel hereby agrees to guarantee the terms of this Agreement and perform
the obligations hereunder if the Company is unable or unwilling to perform
such obligations. A duly authorized representative of Xcel has executed this
Agreement below for the sole purposes of signifying its agreement to this
Section 7.4.

Article 8. Withholding

         The Company shall be entitled to withhold from any amounts payable
under this Agreement all taxes as legally shall be required (including,
without limitation, any United States federal taxes, and any other state,
city, or local taxes).

Article 9. Non-Competition Other Than Upon Change in Control

         9.1 Prohibition on Competition. The Participant agrees that during the
course of the Participant's employment with the Company, without the prior
written consent of the Company, and for one (1) year from the date of the
Participant's voluntary or involuntary termination of employment with the
Company, the Participant shall not:

                                        9
<PAGE>

              (a) Directly or indirectly own, manage, consult, associate with,
                  operate, join, work for, control or participate in the
                  ownership, management, operation or control of, or be
                  connected in any manner with, any business (whether in
                  corporate, proprietorship, or partnership for or otherwise),
                  as more than a 10% owner in such business or member of a group
                  controlling such business, which is engaged in any activity
                  which competes with the business of the company as conducted
                  one (1) year prior to (and up through) the date of the
                  Participant's involuntary or voluntary termination of
                  employment with the Company or which will compete with any
                  proposed business activity of the Company in the planning
                  stage on such date of involuntary or voluntary termination.
                  The participant and the Company agree that this provision is
                  reasonably enforced as to any geographic area.

              (b) Directly or indirectly solicit, service, contract with or
                  otherwise engage any past (one year prior), existing or
                  prospective customer, client or account who then has a
                  relationship with the Company for current or prospective
                  business on behalf of a competitor of the Company, or on the
                  Participant's own behalf for a competing business. The
                  Participant and the Company agree that this provision is
                  reasonably enforced with reference to any geographic area
                  applicable to such relationships with the Company.

              (c) Cause or attempt to cause any existing or prospective
                  customer, client, or account, who then has a relationship with
                  the Company for current or prospective business, to divert
                  terminate, limit or in any manner modify, or fail to enter
                  into any actual or potential business relationship with the
                  Company. The Participant and the Company agree that this
                  provision is reasonably enforced with reference to any
                  geographic area applicable to such relationships with the
                  Company.

              (d) The Company agrees that the terms "activity", "which competes
                  with the business of the Company", "competitor of the
                  Company", "competing business", and "relationship with the
                  Company" as used in this Agreement shall be reasonably
                  construed and applied.

         9.2 Disclosure of Information. The Participant recognizes that he has
access to and knowledge of certain confidential and proprietary information of
the Company, which is essential to the performance of his duties as an employee
of the Company. The Participant will not, during or after the term of his
employment with the Company, in whole or in part, disclose such information to
any person, firm, corporation, association, or other entity for any reason or
purpose whatsoever, nor shall he make use of any information for his own
purposes.

         9.3 Covenants Regarding Other Employees. During the period ending one
(1) year following the payment of Severance Benefits under this Agreement, the
Participant agrees to not

                                       10
<PAGE>

directly or indirectly solicit, employ or conspire with others to employ any of
the Company's employees. The term "employ" for purposes of this paragraph means
to enter into an arrangement for services as a full-time or part-time employee,
independent contractor, consultant, agent or otherwise. The Participant and the
Company agree that this provision is reasonably enforced as to any geographic
area.

Article 10. Non-Disparagement

         10.1 Disparagement. The Participant and the Company, each agrees not to
make any disparaging or negative statements about the Company or the
Participant, including but not limited to its products, services or management
any person or entity whatsoever, including but not limited to past, present and
prospective employees or employers, customers, clients, analysts, investors,
vendors and suppliers.

         10.2 Release. In order to receive the benefits provided under the
Agreement (other than accrued vacation and paid time-off), the Participant will
be required to provide the Company with a release in a form to be provided by
the Company, or, if Xcel provides the benefits, the Participant will be
required to provide Xcel and the Company with a release in a form to be provided
by Xcel. Such release shall fully release the Company or Xcel, as applicable,
and all of its officers, agents, directors, employees, and representatives, any
affiliated companies, businesses or entities, and all other persons and entities
from each and every legal claim or demand of any kind that the Participant ever
had or might have arising out of any action, conduct or decision taking place
during the Participant's employment with the Company, or arising out of the
Participant's separation from that employment, whether or not any such claim
known at the time of separation.

Article 11. Successors and Assignment

         11.1 Successors to the Company. The Company will require any successor
(whether direct or indirect, by purchase, merger, consolidation, or otherwise)
of all or substantially all of the business and/or assets of the Company or of
any division or subsidiary thereof that employed the Participant at the time of
Termination of Employment to expressly assume and agree to perform the Company's
obligations under this Agreement in the same manner and to the same extent that
the Company would be required to perform them if no such succession had taken
place. Failure of the Company to obtain such assumption and agreement prior to
the effective date of any such succession shall be a breach of this Agreement
and shall entitle the Participant to compensation from the Company in the same
amount and on the same terms as he would be entitled to hereunder if he had
terminated his employment with the Company voluntarily for Good Reason. Except
for the purposes of implementing the foregoing, the date on which any such
succession becomes effective shall be deemed the Effective Date of Termination.

         11.2 Assignment by the Participant. This Agreement shall inure to the
benefit of and be enforceable by the Participant's personal or legal
representatives, executors, administrators, successors, heirs, distributes,
devisees, and legatees. If the Participant dies while any amount would still be
payable to him hereunder had he continued to live, all such amounts, unless

                                       11
<PAGE>

otherwise provided herein, shall be paid in accordance with the terms of this
Agreement, to the Participant's Beneficiary. If the Participant has not named a
Beneficiary, then such amounts shall be paid to the Participant's devisee,
legatee, or other designee, or if there is not such designee, to the
Participant's estate.

Article 12. Miscellaneous

         12.1 Beneficiaries. The Participant may designate one or more persons
or entities as the primary and/or contingent beneficiaries of any Severance
Benefits or Change in Control Severance Benefits owing to the Participant under
this Agreement. Such designation must be in the form of a signed writing
