amount of the Initial Contribution to be made in XEL
Stock divided by (y) the average closing

price on the New York Stock Exchange for Xcel common
stock for the last ten full trading days through and
including the Business Day prior to the date when the
portion of the Initial Contribution to be paid in XEL
Stock is made.

(iii) If (1) on the Confirmation Date the Xcel
Debt has retained at least the 4/1/03 Ratings for a
period of at least 120 consecutive days but (2) at
any time after the Confirmation Date and prior to the
Xcel Payment Date the Xcel Debt has not retained at
least the 4/1/03 Ratings for a period of at least 120
consecutive days, then the provisions of subsections
(i) and (ii) above shall apply, but Xcel, in its sole
discretion, may, subject to an NRG Payment Request,
exercise the Xcel Downgrade Election and pay the
requisite XEL Stock no later than the later of (1) 10
Business Days after the Xcel Payment Date and (2) 105
days after the Downgrade Date. In such event, Xcel
shall issue a press release stating the specifics of
its Xcel Downgrade Election no later than five
Business Days after the Downgrade Date. In addition,
if Xcel has exercised an Xcel Downgrade Election
pursuant to this subsection (iii) and has
subsequently received an NRG Payment Revocation, then
Xcel shall pay the portion of the Initial
Contribution subject to the Xcel Downgrade Election
in XEL Stock within the later of (i) 10 Business Days
after receipt of the NRG Payment Revocation and (ii)
105 days after the Downgrade Date.

(iv) In addition to the foregoing, in the event
that on the Xcel Payment Date the Xcel Debt has not
retained at least the 4/1/03 Ratings for a period of
at least 120 consecutive days through and including
the date that the initial portion of the Third
Installment is due, then the due date for the initial
portion of the Third Installment shall be extended to
the later of June 30, 2004 and sixty days after the
Xcel Payment Date.

(g) Tax Treatment of Xcel Contribution. The Parties shall
treat the Xcel Contribution as a contribution to the capital
of NRG for federal, state, and local income tax purposes.

3. Allocation of Xcel Contribution and NRG Releases.

(a) Support Agreement Amount. The Support Agreement
Amount shall be made in exchange for the release of the NRG
Released Causes of Action comprised of the Support Agreement
Claims.

(b) Released-Based Amount. The Release-Based Amount
together with the Xcel Released Causes of Action shall be made
in exchange for the releases described in Sections 3(c) and
(d) hereof and such other releases and injunctions for the
benefit of the Released Parties set forth in the Confirmation
Order.

(c) Check the Box Releases. Subject to the terms of the
Release-Based Amount Agreement, the Released-Based Amount
shall be distributed pro rata to

each allowed Claim in the Unsecured Creditor Class that checks
the appropriate box on a Ballot indicating that the holder of
such Claim is releasing the Released Parties from all NRG
Released Causes of Action and causes the relevant balloting
agent to receive such Ballot by the Voting Deadline. Subject
to paragraph 3(d) of this Agreement, creditors not checking
the box on their Ballots and so causing the relevant balloting
agent to receive such Ballots by the Voting Deadline shall not
receive any portion of the Release-Based Amount; instead, the
aggregate share of the Release-Based Amount of those creditors
who did not check the box on their Ballots which otherwise
would have been payable to such creditors (if they had checked
the box) will be credited against and deducted from the Xcel
Contribution as set forth in the Release-Based Amount
Agreement.

(d) Third Party Releases. Notwithstanding anything to the
contrary in this Agreement, if the third party releases and
injunctions for the benefit of the Released Parties set forth
in sections 9.2 and 9.3 of the NRG Plan are approved in their
entirety pursuant to a Final Order of the Bankruptcy Court in
form acceptable to Xcel, then Xcel shall be obligated to pay
to NRG for distribution to creditors in the Unsecured Creditor
Class the entire $390 million of the Released-Based Amount;
provided, however, (a) the timing of the payment of the Third
Installment shall not be altered by an obligation to pay the
entire $390 million of Released-Based Amount, and (b) until
there is such a Final Order of the Bankruptcy Court, Xcel's
obligation to pay the Released-Based Amount shall be as
otherwise set forth in this Agreement and the Released-Based
Amount Agreement. In addition, if the third party releases and
injunctions for the benefit of the Released Parties set forth
in sections 9.2 and 9.3 of the NRG Plan are approved in their
entirety pursuant to a Final Order of the Bankruptcy Court in
form acceptable to Xcel, the Released-Based Amount Agreement
shall not be effective except for the indemnity provisions set
forth in section 9 thereof and any other portion of that
agreement applicable to section 9.

4. Xcel Tax Benefit. The Parties agree that:

(a) Worthless Stock Deduction. For federal income tax
purposes, after the Effective Date Xcel or its Affiliates
shall claim the Worthless Stock Deduction for the Loss Year.
Neither Xcel nor any of its Affiliates shall claim the
Worthless Stock Deduction for any year before the Loss Year.

(b) Tax Related Plan Provisions.

(i) The Xcel Tax Benefit shall be the sole and
exclusive property of Xcel, and the NRG Entities and
any party claiming by or through them hereby release
as of the Effective Date any right or interest that
they might otherwise have in the Xcel Tax Benefit.

(ii) NRG and its direct and indirect subsidiaries
shall not be (a) reconsolidated with Xcel or any of
its other Affiliates for tax purposes at any time
after their March, 2001 deconsolidation unless
otherwise

required by state or local tax law, or (b) treated as
a party to or otherwise entitled to the benefits of
any tax sharing agreement with Xcel, other than the
Tax Matters Agreement.

5. Xcel Guaranties, Insurance, and Intercompany Claims.

(a) Xcel Guaranties and Insurance. The Parties agree
that:

(i) On the Effective Date, all Guarantees shall
either be terminated or Xcel and NRG shall enter into
other arrangements satisfactory to Xcel and NRG with
respect to such obligations (with Xcel and any
Affiliates thereof having no further liability for
such obligations or arrangements) and all cash
collateral posted by Xcel or any Affiliate shall be
returned as soon as practicable to Xcel, including,
if not previously returned, the $11.5 million of cash
collateral posted by Xcel for the Mid-Atlantic
project. With respect to the $11.5 million of cash
collateral posted by Xcel for the Mid-Atlantic
project, NRG shall cooperate with Xcel in seeking the
return at the earliest practical date after the
current expiration of the relevant Mid-Atlantic
agreement in July of 2003.

(ii) NRG and the NRG Subsidiaries shall be solely
responsible for renewing, administering, and paying
for their own insurance policies starting with
insurance policies relating to property and other
coverages expiring as of June 2003, and D&O Policies
expiring on the D&O Expiration Date; provided,
however, that Xcel shall (1) not cancel any D&O
Policy before the D&O Expiration Date, (2) reasonably
cooperate with NRG's past or current officers and
directors who may be entitled to coverage under any
D&O Policy to allow them to administer their claims,
and (3) if available and at the sole cost of NRG, and
after receiving sufficient funds from NRG, at NRG's
request purchase customary tail coverage, commencing
on the D&O Expiration Date, for NRG's officers and
non-Xcel directors in office on the day prior to the
Petition Date and who are eligible for coverage under
any D&O Policy.

(iii) The Parties acknowledge and agree that the
rights and obligations of Xcel, NRG, and all other
persons or entities insured under any D&O Policy have
been and shall remain unaffected by the Chapter 11
Cases or any subsequent bankruptcy cases or
proceedings commenced by any of the NRG Subsidiaries
and that upon the Effective Date, Xcel, NRG, and all
other persons or entities insured under any D&O
Policy shall have the same status with respect to,
and rights under, any D&O Policy as immediately prior
to the Petition Date, notwithstanding, among other
things, the automatic stay in the Chapter 11 Case for
NRG previously in effect or the automatic stay that
may thereafter remain in effect in the chapter 11
case of any other NRG Subsidiary.

(b) Intercompany Claims. The Parties agree that:

(i) Any prepetition or postpetition Claims of
Xcel or any Affiliate against any of the NRG Entities
arising from the provision of intercompany goods or
services of the type set forth on Schedule 5(b)(i)
hereto to any of the NRG Entities or from payment by
Xcel or any Affiliate under any Guaranty shall be
paid in full in cash by NRG in the ordinary course
(including payment during the Chapter 11 Cases) in
the appropriate amount based on the underlying
contracts or agreements between the parties
(including all agreements listed on Schedule 8(m) to
this Agreement), without any subordination or
recharacterization of such Claims, except that the
Claims which are to be paid in full in the ordinary
course during the Chapter 11 Cases shall not include
Claims of Xcel or any Affiliate arising under the
Guarantees listed in Schedule 5(b)(i) hereto (such
Claims, subject to the next sentence, to be paid in

in clause (ii) below) but shall include any Claims of
Xcel or any Affiliate related to Northern States
Power Company, NRG Energy Center-Rock Tenn LLC, NRG
Thermal f/k/a Norenco Corporation, NRG Resource

LLC, and NRG Energy, Inc. Notwithstanding the
foregoing, (A) Settled Claims shall not be paid until
the Effective Date, at which time Xcel shall receive,
on account of and in full and final settlement of
such Claims, the Xcel Plan Note; and (B) after
January 31, 2003 NRG shall only be responsible under
the Services Agreement for Reimbursable Claims. NRG
agrees that it shall not order services from Xcel or
any Affiliate under the Services Agreement or
otherwise inconsistent with any provisions of this
Agreement.

(ii) To the extent, if any, that intercompany
Claims of Xcel or any Affiliate (other than Settled
Claims and other than Claims under the Services
Agreement which are not Reimbursable Claims, but
including Claims for reimbursement of payments made
by Xcel or any Affiliate under Guarantees) are unpaid
as of the Petition Date, such amounts shall be paid
in full in cash on the Effective Date by the relevant
NRG Entity or NRG under the NRG Plan without any
subordination or recharacterization of such Claims.

(iii) The provisions of clauses (i) and (ii) of
this Section 5(b) shall not apply to any tax sharing
agreement. All tax sharing agreements or
understandings to the extent otherwise binding on
Xcel and NRG, shall terminate (without any residual
or ongoing liability of either party to the other) as
of the Effective Date for all taxable periods, past,
present and future. On and after the Effective Date,
tax matters between NRG, Xcel, and any Affiliates
thereof shall be governed exclusively by the Tax

during the Chapter 11 Cases.

(g) NRG represents that all NRG Subsidiaries, except for
Xxxx Xx Energy Development Company Ltd. and NRG Gladstone

(e) Except to the extent otherwise provided in the NRG
Plan, NRG shall use its reasonable best efforts to cause all
NRG Subsidiaries which become part of the Chapter 11 Cases or
other bankruptcy cases or proceedings instituted as part of
the reorganization of the NRG Entities to seek a Final Order
in a form acceptable to Xcel from the Bankruptcy Court making

Claims, Causes of Action, remedies, defenses, setoffs, rights or other benefits
of the Parties or any of their respective Affiliates shall be fully preserved
without any estoppel, evidentiary or other effect of any kind or nature
whatsoever. Upon Xcel's determination, which may not be unreasonably delayed,
that each of the foregoing conditions has been satisfied in accordance with the
terms of this Agreement, Xcel shall deliver a written notice to NRG stating as
such and that the effective date of this Agreement has occurred. For purposes of
any agreement or document contemplated by this Agreement, including the NRG
Plan, the "Effective Date" of this Agreement shall be the date on which Xcel

10. Termination. If all of the conditions set forth in section 8

claim of any Party for breach of this Agreement shall survive
termination and all rights and remedies with respect to such claims
shall not be prejudiced in any way.

11. Indemnification by NRG. NRG shall, for itself and on behalf
of each of the NRG Subsidiaries, and as agent for each NRG Subsidiary,
indemnify, defend (or, where applicable, pay the reasonable defense
costs for) and hold harmless the Released Parties from and against any
and all Liabilities that any entity seeks to impose upon the Released
Parties, or which are imposed upon the Released Parties, if and to the
extent such Liabilities relate to, arise out of or result from the
failure of any NRG Subsidiary to pay its creditors in full except to
the extent provided for in the NRG Plan and except with respect to (i)
LSP-Pike Energy, LLC, (ii) LSP-Xxxxxx Energy, LLC, (iii) NRG Xxxxxx
Turbines, LLC, (iv) NRG Gila Bend Holdings, and (v) NRG Audrain
Generating LLC, or the failure to have the provisions of sections 9.2,
9.3.B., 9.3.C., and 9.3.G. of the NRG Plan be fully applicable pursuant
to a Final Order of the Bankruptcy Court to any Non-Plan Debtor or any
NRG Subsidiary which subsequently becomes part of the Chapter 11 Cases
or other bankruptcy cases or proceedings.

12. Release and Covenant Not to Xxx.

(a) Release. As of the Effective Date, for good and
valuable consideration, the adequacy of which is hereby
confirmed, each of the NRG Entities, in their individual
capacities and, to the extent applicable, as debtors in
possession for and on behalf of their estates and any entity
that may assert a Claim or Cause of Action derivatively or
otherwise, hereby release and discharge, absolutely,
unconditionally, irrevocably and forever, the Released Parties
from any and all NRG Released Causes of Action.

(b) Applicability of Release to Transferees. The releases
set forth in Section 12(a) above shall be binding upon all
Transferees of the releasing party.

(c) Binding Effect of Releases. Each party to which the
releases set forth in Section 12(a) above applies shall be
deemed to have granted such release notwithstanding that it
may hereafter discover facts in addition to, or different
from, those which it now knows or believes to be true, and
without regard to the subsequent discovery or existence of
such different or additional facts, and such party expressly
waives any and all rights that it may have under any statute
or

common law principle, including section 1542 of the California
Civil Code, which would limit the effect of such releases to
those Claims or Causes of Action actually known or suspected
to exist at the time of execution of the release. Section 1542
of the California Civil Code generally provides as follows: "a
general release does not extend to claims which the creditor
does not know or suspect to exist in his favor at the time of
executing the release, which if known by him may have
materially affected his settlement with the debtor."

(d) NRG Entity Covenant Not to Xxx. As of the Effective
Date, for good and valuable consideration, the adequacy of
which is hereby confirmed, each of the NRG Entities, in their
individual capacities and, to the extent applicable, as
debtors in possession for and on behalf of their estates and
any entity that may assert a claim or cause of action
derivatively or otherwise, hereby covenant and agree not to
commence or prosecute any lawsuit or other legal action,
proceeding, or arbitration against any of the Released Parties
in respect of any and all NRG Released Causes of Action.

(e) Xcel Covenant Not to Xxx. As of the Effective Date,
for good and valuable consideration, the adequacy of which is
hereby confirmed, Xcel and, to the extent applicable, any
entity that may assert a claim or cause of action derivatively
or otherwise, hereby covenants and agrees not to commence or
prosecute any lawsuit or other legal action, proceeding, or
arbitration against any of the NRG Entities in respect of any
and all Xcel Released Causes of Action.

13. Miscellaneous Provisions.

(a) Specific Performance. It is understood and agreed
that money damages would not be a sufficient remedy for any
breach of this Agreement, and each non-breaching Party shall
be entitled to specific performance and injunctive or other
equitable relief as a remedy for such breach.

(b) Successors and Assigns. This Agreement is intended to
bind and inure to the benefit of each of the Parties and each
of their respective successors, assigns, heirs, executors,
administrators, and representatives.

(c) Governing Law; Jurisdiction. This Agreement will be
governed by the laws of the State of New York, without regard
to its conflicts of laws principles that would require the law
of another jurisdiction to be applied. Through the first
anniversary of the Effective Date, each of the Parties
irrevocably (a) submits and consents in advance to the
exclusive jurisdiction of the Bankruptcy Court for the purpose
of any action or proceeding in which any NRG Entity is a party
arising out of or relating to this Agreement; (b) agrees that
all claims in respect to such action or proceeding may be
heard and determined exclusively in such court; and (c) waives
any objection that such Party may have based upon lack of
personal jurisdiction, improper venue, or forum non
conveniens.

(d) Entire Agreement. This Agreement, the exhibits and
schedules hereto, and the applicable provisions in the NRG
Plan constitute the complete and entire agreement between the
Parties with respect to the matters contained in this
Agreement, and supersede all prior agreements, negotiations,
and discussions between the Parties with respect thereto.

(e) Non-Reliance. Each of the Parties acknowledges that,
in entering into this Agreement, it is not relying upon any
representations or warranties made by anyone other than those
representations, warranties, terms and provisions expressly
set forth in this Agreement, the exhibits and schedules
hereto, and the applicable provisions in the NRG Plan.

NOTE "A":

Any transactions that were entered into with a CP on or before the expiration
date of the guaranty will be covered through the duration of the trade(s) on an
"evergreen" basis. Thus, for Aquila, El Paso, and PGET Power, all trade
obligations of NRG were entered into prior to the expiration dates of those
guaranties, even though the periods ultimately covered under those trade
obligations are relatively far out into the future (to 12/03 for Aquila and PGET
Power, to 12/06 for El Paso). The inclusion of a guaranty or other item on this
Schedule VI.D. which has expired shall not be deemed a statement that such
guaranty or other item is otherwise effective or in force or effect.
