         This Agreement, is made and entered into as of December 5, 2003, by and

         WHEREAS, on May 14, 2003, NRG filed a voluntary petition for relief
under chapter 11 of the Bankruptcy Code with the Bankruptcy Court.

         WHEREAS, NRG and certain of the NRG Subsidiaries have filed with the
Bankruptcy Court Debtors' Second Amended Joint Plan of Reorganization Pursuant
to Chapter 11 of the Bankruptcy Code dated October 10, 2003 (as amended,
supplemented or otherwise modified from time to time, the "Plan").

         WHEREAS, the Plan contemplates that Xcel will pay up to $390 million to
NRG pursuant to the Settlement Agreement in exchange for the releases of certain
liabilities and claims against the Released Parties.

         WHEREAS, a condition precedent to effectiveness of the Plan and the
obligations of Xcel to pay the Release-Based Amount to NRG is that Creditors
holding 85% of the NRG Unsecured Claims properly make the Release Election (the
"85% Condition"), unless such Creditors are otherwise bound to a release of
certain liabilities and claims against the Released Parties by a Final Order
acceptable to Xcel confirming the Plan.

         WHEREAS, the Plan contemplates this Agreement specifying the details as
to how to calculate whether the 85% Condition has been satisfied and the
Release-Based Amount payable by Xcel to NRG at any time based upon the allowance
and/or estimation of Claims and other factors.

         WHEREAS, this Agreement shall be incorporated into the Plan as an
exhibit thereto.

         (a)      Releasing Creditors. Except as may otherwise be agreed by Xcel
                  and NRG in writing, the amount of the Claim of a Releasing
                  Creditor shall be deemed to be the amount of (i) if such Claim

                  the Schedules or (b) the amount as reflected on the most
                  recently filed proof of Claim (if liquidated), or (ii) if the
                  Claim is not listed in the Schedules or is listed in the
                  Schedules as contingent, unliquidated, or disputed, zero
                  dollars ($0.00). In addition, such deemed amount shall be
                  reduced (but not below zero dollars ($0.00)) by the amount(s)
                  paid or to be paid to such Creditor on account of such Claim
                  prior to the Effective Date. Upon entry of a Final Order
                  providing for the Allowed amount of a Claim (including
                  allowance at an amount equal to $0), the amount of such Claim
                  for purposes of the 85% Condition shall be the Allowed amount.

         (b)      Non-Releasing Creditor. The amount of the Claim of a
                  Non-Releasing Creditor shall be deemed to be the Maximum
                  Amount of such Claim. Subject to paragraph 7, upon entry of a
                  Final Order providing for the Allowed amount of a Claim
                  (including allowance at an amount equal to $0), the amount of
                  such Claim for purposes of the 85% Condition shall be the
                  Allowed amount.

         (c)      Claims Against NRG and an NRG Subsidiary. The provisions of
                  paragraph 3 shall apply to the calculation with respect to the
                  85% Condition.

3.                Calculation of Claim Amount for A Creditor with Claims against
         NRG and An NRG Subsidiary.

         (a)      If a Creditor with a Claim against NRG and an NRG Subsidiary
                  as of the date an order for relief was entered with respect to
                  such entity agrees to eliminate such Claim against NRG as a
                  result of separate consideration from an NRG Subsidiary, such
                  Creditor shall have been deemed to have retained its Claim
                  against NRG for purposes of this Agreement unless (i) such
                  Creditor's claim against the NRG Subsidiary is unimpaired, but
                  if and only to the extent that satisfaction of such claim by
                  the NRG Subsidiary would satisfy such Claim against NRG, or
                  (ii) such Creditor agrees to release all of its NRG Released
                  Causes of Action against the Released Parties as part of the
                  elimination of its Claim against NRG.

         (b)      If a Creditor is deemed to have retained its Claim against NRG
                  as described above, the amount of such Claim shall be based
                  upon the Maximum Amount and resolved and determined by the
                  same method as applies to other Claims subject to this
                  Agreement.

                                       5


4.                Payment by Xcel to NRG of the Release-Based Amount on Account
         of Releasing Creditors.

         (a)      Aggregate Payment by Xcel. Subject to the resolution of this
                  amount in accordance with paragraph 8, as of any Subsequent
                  Payment Date, the aggregate Release-Based Amount payable
                  (inclusive of amounts previously paid) by Xcel to NRG for
                  distribution to the Releasing Creditors shall be the product
                  of (i) the applicable Release-Based Maximum Amount, (ii) the
                  quotient of (a) the aggregate Allowed Claims of the Releasing
                  Creditors and (b) the aggregate of the Maximum Amount of all
                  Claims (whether or not the Creditors of such Claims are
                  Releasing Creditors), and (iii) either (a) on any Subsequent
                  Payment Date other than the Final Payment Date, 1.0 minus the
                  Xcel Reserve Retainage, or (b) on the Final Payment Date, 1.0.

         (b)      Calculation of Additional Amount. The Additional Amount, as of
                  each Subsequent Payment Date, shall be the difference between
                  the Aggregate Payment Amount and the aggregate amount
                  previously paid by Xcel

         (c)      Payments on Second Installment Date. Notwithstanding paragraph
                  4(a), on the Second Installment Date Xcel shall pay to NRG for
                  distribution to the Releasing Creditors on account of their
                  Allowed Claims $38 million or such number of shares of Xcel
                  common stock as is permitted by the Settlement Agreement.

         (d)      Payments on Subsequent Payment Dates. On each Subsequent
                  Payment Date, Xcel shall pay to NRG for distribution to the
                  Releasing Creditors (i) first, to each Releasing Creditor
                  holding a Claim that had not been Allowed as of the
                  immediately preceding Date of Determination but that has
                  subsequently been Allowed, the Pro Rata Share of the
                  Release-Based Amount (without any interest thereon) such
                  Releasing Creditor would have received from NRG had such Claim
                  been an Allowed Claim as of the Effective Date and Xcel had
                  made payments to NRG in accordance with this Agreement on
                  account of such Claim from and after the Effective Date, and
                  (ii) then, to all Releasing Creditors holding Allowed Claims,
                  the their Pro Rata Share of the Additional Amount (as reduced
                  by the payment made in clause (i) hereof).

         (e)      Limitation of Payments. Notwithstanding anything to the
                  contrary contained herein, Xcel shall not be obligated to pay
                  to NRG any amount so that after giving effect to such payment,
                  the aggregate amount paid (including such payment) exceeds the
                  Aggregate Payment Amount as calculated in accordance with
                  paragraph 8. In the event of overpayment on any prior
                  Subsequent Payment Date (including an overpayment caused by an
                  adjustment of Allowed Claims or to the Maximum Amount), such
                  overpayment shall be reflected in a reduction in the
                  Additional Amount payable on the next Subsequent Payment Date.

         (f)      Additional Payment When Retained Amount Exceeds Maximum
                  Allocation to Non-Releasing Creditors. If, as of any
                  Subsequent Payment Date, (i) the difference between (a) the
                  Release-Based Maximum Amount and (b) the

                                       6


                  aggregate amount already paid or to be paid on such Subsequent
                  Payment Date by Xcel pursuant to this Agreement exceeds (ii)
                  the aggregate Maximum Amount of Claims of Non-Releasing
                  Creditors, then Xcel shall pay to NRG the amount of such
                  difference on such Subsequent Payment Date.

5.                Adjustments to the Release-Based Amount on the Subsequent
         Payment Dates Based Upon Reconsideration or Liquidation of Claim. On
         each Subsequent Payment Date, if, for any reason, including, without
         limitation, the reconsideration of a Claim pursuant to section 502(j)
         of the Bankruptcy Code, the allowance or liquidation of a Claim in
         excess of the Maximum Amount, an amendment to the Schedules or a proof
         of Claim, or the creation of additional prepetition Claims by virtue of
         sections 502(g) or (h) of the Bankruptcy Code, a Supplemental
         Distribution Claimant has received a smaller distribution (calculated
         as a percentage) than other Releasing Creditors holding Allowed Claims,
         NRG shall pay such Supplemental Distribution Claimant from the
         Additional Amount an amount sufficient to achieve the same distribution
         (calculated as a percentage) as other Releasing Creditors holding
         Allowed Claims who have already received a distribution. If the
         Additional Amount with the deduction of the Xcel Reserve Retainage paid
         to NRG is insufficient to permit all such Supplemental Distribution
         Claimants to receive the same distribution (calculated as a percentage)
         as other Releasing Creditors holding Allowed Claims, all of the
         Additional Amount shall be distributed to the Supplemental Distribution
         Claimants so that each Supplemental Distribution Claimants receives, as
         nearly as possible, the same distribution (calculated as a percentage).

6.                Estimation of Maximum Amount.

         (a)      Estimation by the Bankruptcy Court. For purposes of this
                  Agreement, NRG or Reorganized NRG may, at any time and from
                  time to time, request that the Bankruptcy Court determine the
                  Maximum Amount of any unliquidated, disputed, or contingent
                  Claim pursuant to section 502(c) of the Bankruptcy Code
                  regardless of whether NRG, Reorganized NRG, the statutory
                  committee of unsecured creditors, or any other party in
                  interest (as applicable) previously objected to such Claim or
                  whether the Bankruptcy Court has ruled on any such objection,
                  and the Bankruptcy Court will retain jurisdiction to estimate
                  any Claim at any time during litigation concerning any
                  objection to any Claim including during the pendency of any
                  appeal relating to any such objection.

         (b)      Estimation Conditions. It shall be a condition to occurrence
                  of the Effective Date of the Settlement Agreement, waivable by
                  Xcel, that there shall have been entered a Final Order
                  determining the Maximum Amount of the Claim of any
                  Non-Releasing Creditor which the Maximum Amount is Material.
                  It shall be a condition to Xcel's obligation to pay any of the
                  Release-Based Amount that there shall have been entered a
                  Final Order determining the Maximum Amount of the Claim of any
                  Releasing Creditor which is not Allowed and for which the
                  Allowed amount of such Claim could be Material.

                                       7


         (c)      Estimation By Agreement. NRG and Xcel shall use their
                  reasonable best efforts to determine the Maximum Amount of
                  each Claim that could be Material. Xcel and NRG may reasonably
                  estimate the Maximum Exposure on account of any Claim (or the
                  aggregate of the Claims) of the Non-Releasing Creditor(s). If
                  Xcel and NRG cannot agree on an amount, the Court may estimate
                  the Maximum Exposure of any Claim and, if the Court declines
                  to do so, the Maximum Exposure shall be the amount estimated
                  by Xcel.

7.                Calculation of Allowed Claims With Non-Releasing Creditors.
         Upon the allowance of a Claim of any Non-Releasing Creditor, NRG shall
         use its commercially reasonable best efforts to obtain the Claims
         Resolution Release, which if obtained, shall reduce the Maximum Amount
         to the Allowed Amount. If an action has been commenced against Xcel,
         the Maximum Amount shall be increased or decreased, as the case may be,
         based upon Xcel's costs (including reasonable attorneys' fees) and
         liability, if any, resulting from a Final Order determining such Claim
         or settlement thereof.

8.                Resolution of Aggregate Payment Amount as of Date of
         Determination. Fifteen calendar days after each Date of Determination,
         NRG shall deliver to Xcel a written report setting forth NRG's
         calculation of the Aggregate Payment Amount. The report shall include a
         record of Claims that were Allowed or not Allowed subsequent to the
         prior Date of Determination, copies of any stipulations, orders,
         releases, and any other documentation related to such Claim, and a
         reconciliation of each Claim against such Claim's prior Maximum Amount
         (and for Claims of holders of NRG's public securities, a reconciliation
         of such Claims held by such Releasing Creditors against the amount of
         such securities actually tendered by such Releasing Creditors). In
         addition, the report shall include any adjustments to such calculation
         of the Aggregate Payment Amount as may be required by paragraph 5. Xcel
         will have 20 calendar days to review the report and calculate the
         Aggregate Payment Amount. If the Parties disagree as to the Aggregate
         Payment Amount, the Parties shall proceed in good faith to reconcile
         the calculations. If the Parties cannot reconcile such amounts, on the
         applicable Subsequent Payment Date, Xcel shall pay the undisputed
         Additional Amount to NRG. Any disputed amount to which Xcel
         subsequently agrees shall be paid to NRG on the next Subsequent Payment
         Date as if such amount had been agreed on the prior Subsequent Payment
         Date. All disputed amounts with respect to the Aggregate Payment Amount
         shall be agreed to, or determined by the Bankruptcy Court, prior to the
         Final Payment Date.

9.                Indemnification.

         (a)      Claims By Creditors. NRG shall indemnify Xcel or any Released
                  Party for any loss, claim or damages (including, without
                  limitation, reasonable attorneys' fees, litigation costs and
                  expenses) incurred by Xcel or any Released Party as a result
                  of any action by (i) a Releasing Creditor arising from or
                  relating to any claim that the Releasing Creditor did not
                  receive its correct Pro Rata Share of the Release-Based Amount
                  for any reason whatsoever, including, without limitation,
                  because of the reconsideration of its claim pursuant to
                  section 502(j) of the Bankruptcy Code, provided that there
                  shall be no indemnity if Xcel and NRG actually agree in
                  writing as to the amount to pay a particular Releasing
                  Creditor and such Releasing

                                       8


                  Creditor receives such amount from NRG, or (ii) any creditor
                  arising from or relating to the fact that such creditor did
                  not receive proper notice with respect to any matter relating
                  to the Chapter 11 Cases.

         (b)      Allowed Claim Subsequently Not Allowed. If any Claim is
                  reported to Xcel pursuant to paragraph 8 as Allowed and NRG
                  subsequently determines that such Claim is not Allowed (or is
                  Allowed in a lesser amount than previously reported), NRG
                  shall pay to Xcel, upon demand, the amount such Releasing
                  Creditor has received, or if such Claim is Allowed in a lesser
                  amount, the excess of such amount over the amount such
                  Releasing Creditor would have received had its Allowed Claim
                  been reported in the lesser amount.

10.               No Interest. Except as provided in paragraph 2(c) of the
         Settlement Agreement, any payments to be made by Xcel under this
         Agreement shall not include, and Xcel shall have no liability for, any
         interest with respect thereto.

11.               Conditions. The obligation of Xcel to pay any Release-Based
         Amount pursuant to this Agreement is subject to, and conditioned upon,
         the satisfaction or waiver by Xcel of any condition to the performance
         of Xcel's obligation under the Settlement Agreement as of the Effective
         Date.

12.               No Additional Payment By Xcel. In no event shall Xcel pay to
         NRG more than the product of (a) $390 million and (b) the quotient of
         (x) the Allowed Claims of the Releasing Creditors and (y) all Allowed
         Claims, regardless of whether any particular Creditor receives less
         than its Pro Rata Share of the Release-Based Amount. In no event shall
         Xcel be obligated under this Agreement to make any payment to NRG after
         the Final Payment Date assuming all amounts due are paid.

13.               No Liability of Xcel to Creditors. Xcel shall have no
         liability to any Creditor of a Claim with respect to this Agreement.

14.               Access to Ballots and Claims. NRG shall, or shall cause the
         claims agent appointed in NRG's bankruptcy case (or any ballot or
         solicitation agent) to make available to Xcel access to all ballots and
         proofs of claim, all reports and summaries related thereto, and any
         other information related to the same, and to take all other actions
         Xcel may reasonably request in connection with any matter relating to
         this Agreement.

15.               Amendment or Waiver. Except as otherwise specifically provided
         herein, this Agreement may not be modified, amended or supplemented
         without the prior written consent of the Parties. No waiver of any of
         the provisions of this Agreement shall be deemed or constitute a waiver
         of any other provision of this Agreement, whether or not similar, nor
         shall any waiver be deemed a continuing waiver.

16.               Notices. Any notice required or desired to be served, given or
         delivered under this Agreement shall be in writing, and shall be deemed
         to have been validly served, given or delivered if provided by personal
         delivery, or upon receipt of fax delivery, as follows:

         By its execution and delivery of this Agreement, each of the Parties
         hereto hereby irrevocably and unconditionally agrees for itself that
         any legal action, suit or proceeding against it with respect to any
         matter under or arising out of or in connection with this Agreement or
         for recognition or enforcement of any judgment rendered in any such
         action, suit or proceeding, shall be brought exclusively in the
         Bankruptcy Court and each of the Parties hereto irrevocably accepts and
         submits itself to the exclusive jurisdiction of each such court,
         generally and unconditionally, with respect to any such action, suit or
         proceeding, and waives any objection it may have to venue or the
         convenience of the forum.

18.               Termination. This Agreement shall terminate upon (i) the third
         party releases and injunctions for the benefit of the Released Parties
         set forth in Sections 9.2 and 9.3 of the Plan being approved in their
         entirety pursuant to a Final Order in form acceptable to Xcel or (ii)
         the occurrence of the Final Payment Date. The provisions of paragraph 9
         and any other provisions applicable to paragraph 9 shall survive
         termination of this Agreement.

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

20.               Headings and References. The headings of the sections,
         paragraphs and subsections of this Agreement are inserted for
         convenience only and shall not affect the interpretation hereof.
         Reference to a paragraph shall refer to paragraphs of this Agreement
         unless the context requires otherwise.

21.               Interpretation. This Agreement is the product of negotiations
         of the Parties, and in the enforcement or interpretation hereof, is to
         be interpreted in a neutral manner, and any presumption with regard to
         interpretation for or against any Party by reason of that Party having
         drafted or caused to be drafted this Agreement, or any portion hereof,
         shall not be effective in regard to the interpretation hereof.

23.               No Third-Party Beneficiaries. This Agreement shall be solely
         for the benefit of the Parties hereto and no other person or entity
         shall be a third-party beneficiary hereof. The obligations of Xcel
         pursuant to this Agreement are to NRG only and do not run to and are
         not enforceable directly by any Creditor; provided, however, that any
         Creditor shall have the right to demand that NRG enforce NRG's rights
         under this Agreement. In the event NRG fails to enforce this Agreement,
         NRG and Xcel agree that any Creditor may do so in the name of NRG;
         provided; however, that Xcel shall be required to defend enforcement
         actions in only one proceeding.

24.               No Admissions. This Agreement shall in no event be construed
         as or be deemed to be evidence of an admission or concession on the
         part of any Party or any Creditor of any claim or fault or liability or
         damages whatsoever. Each of the Parties denies any and all wrongdoing
         or liability of any kind and does not concede any infirmity in the
         Claims or defenses which it has asserted or could assert.

25.               Counterparts. This Agreement may be executed in one or more
         counterparts, each of which shall be deemed an original and all of
         which shall constitute one and the same Agreement. Delivery of an
         executed signature page of this Agreement by facsimile shall be
         effective as delivery of a manually executed signature page of this
         Agreement.

26.               Entire Agreement. This Agreement constitutes the entire
         agreement between the Parties with respect to the calculation of the
         Release-Based Amount and the determination of the satisfaction of the
         85% Condition and supersedes all prior and contemporaneous agreements,
         representations, warranties and understandings of the Parties, whether
         oral, written or implied, as to the subject matter hereof and does not
         supersede the Plan (including the exhibits thereto) with respect to the
