                  4.1.1    Supply Amount. Supplier shall be required to provide
                           -------------
                           the Supply Amount in any Dispatch Hour. As provided
                           in Section 5.1, Buyer shall makereasonable efforts to

                           necessary to satisfy Buyer's TRR.

                           4.1.1.1  With the Buyer's prior consent, not to be
                                    unreasonably withheld or delayed, Supplier
                                    shall be entitled to generate or otherwise
                                    procure the Supply Amount from sources other
                                    than the Asset Bundle.

                           4.1.1.2  Supplier shall deliver the Supply Amount to
                                    Buyer during the Dispatch Hour on a
                                    continuous basis at the Point(s) of Delivery
                                    and shall schedule the Supply Amount in
                                    accordance with the Buyer's OATT or the

                           4.1.1.3  The Buyer at its sole discretion shall
                                    designate the allocation of the Supply

                                    notification provisions of Section 5.

                                    4.1.1.3.1 The Parties recognize that
                                              operation of the Asset Bundle is
                                              subject to, and thus the Supply
                                              Amount at times may be limited by,
                                              the operational parameters of the
                                              Asset Bundle. The Parties further
                                              recognize that the consolidation
                                              of two or more generating units
                                              into an Asset Bundle precludes
                                              contractual provisions addressing
                                              such operational parameters in a
                                              matter normally applied to Energy
                                              purchases from specified
                                              generating units. Consequently,
                                              Supplier will have the right to
                                              raise concerns regarding the
                                              effect of such operational
                                              parameters upon Buyer's scheduling
                                              requests, and Buyer will make good
                                              faith efforts to alleviate
                                              Supplier's concerns.

                                    4.1.1.3.2 The Parties further recognize that
                                              the Asset Bundle also is subject
                                              to the contractual and operating
                                              constraints set forth in Exhibit
                                              M.

                  4.1.2    Minimum Annual Energy Take. The Buyer shall accept a
                           --------------------------
                           minimum annual energy take during each Contract Year.
                           The Minimum Annual Energy Take shall be set forth on

                                    Buyer shall have the right to reduce the
                                    Minimum Annual Energy Take if the number of
                                    customers taking electric service from Buyer
                                    falls below the number of customers on
                                    December 31, 2000. Adjustments will be
                                    applicable, on a pro rata basis, on the
                                    first (1st) day of the month immediately
                                    following Supplier's receipt of Buyer's
                                    notice of adjustment. Buyer shall provide

                           --------------------------
                           Minimum Hourly Energy Take for any Dispatch Hour if
                           the Supply Amount, or a portion thereof, is provided
                           to Buyer from the Asset Bundle. The Minimum Hourly
                           Energy Take is stated in Exhibit A.

                           4.1.3.1  Buyer's Obligation to Take. If Buyer is

                                    unwilling to accept the Minimum Hourly
                                    Energy Take, the difference (in MWh) between
                                    the Supply Amount of Energy (including
                                    consideration for Energy that would have
                                    been taken but was unavailable due to
                                    Permitted Deratings or Force Majeure, as
                                    well as the Total Amount of Energy Replaced)
                                    and Minimum Hourly Energy Take shall be
                                    billed at the Price Ceiling of Energy less
                                    the Price Floor of Energy.

                  4.1.4    Supplier Rights to Output. Supplier may sell to
                           -------------------------
                           others any portion of the Asset Bundle Capacity in
                           excess of the Supply Amount.

                  4.1.5    Point(s) of Delivery. Supplier shall deliver, and
                           --------------------

                           Energy at the Point(s) of Delivery. Subject to
                           Section 4.1.6.2, Supplier shall be responsible for
                           all costs associated with delivery of the Supply
                           Amount of Energy to the Point(s) of Delivery.

                  4.1.6    Alternative Points of Delivery. For any Dispatch
                           ------------------------------
                           Hour, either Party may designate one or more
                           alternative Points of Delivery, subject to the other
                           Party's prior approval and consistent with the
                           Buyer's OATT or the ISA's OATT, as applicable, such
                           approval not to be unreasonably withheld or delayed.

                           4.1.6.1  If Supplier has designated an alternative
                                    Point of Delivery, Supplier shall be
                                    responsible for all costs of delivery to
                                    such alternative Point of Delivery.

                           4.1.6.2  If Buyer has designated an alternative Point
                                    of Delivery, Buyer shall be responsible for
                                    all costs of delivery to such alternative

                  4.1.7    Fuel. Buyer shall have no responsibility for any fuel
                           ----
                           procurement or fuel transportation costs or
                           activities associated with the Asset Bundle during
                           the term of this Agreement.

                  4.1.8    Resale. Except as provided in the next sentence, the
                           ------
                           Supply Amount may be resold by Buyer only as
                           necessary to satisfy Buyer's TRR. If, after
                           submitting the request of the Supply Amount pursuant
                           to Section

                                       13


                           5.1, the Buyer determines that the scheduled Supply
                           Amount, together with purchases scheduled under
                           Buyer's other Transitional Power Purchase Agreements,
                           exceeds Buyer's most current projected TRR, then the
                           Buyer also shall resell at wholesale that amount of
                           Energy in excess of Buyer's actual TRR as necessary
                           to balance its load and resources.

                  4.1.9    Right to Review. Buyer and Supplier each shall have
                           ---------------
                           the right to review during normal business hours the
                           relevant books and records of the other Party to
                           confirm the accuracy of such as it pertains to
                           transactions under this Agreement. The review shall
                           be consistent with standard business practices and
                           shall follow reasonable notice to the other Party.
                           Reasonable notice for a review of the previous
                           month's records shall be at least a twenty-four (24)
                           hour period from a Business Day to a subsequent
                           Business Day. If a review is requested of other than
                           the previous month's records, then notice of that
                           request shall be provided with a minimum of seven (7)
                           calendar days written notice by the requesting Party.
                           The notice shall specify the period to be covered by
                           the review. The Party providing records can make
                           reasonable requests that the receiving Party keep the
                           records confidential, and the receiving Party shall
                           take reasonable steps to accommodate such requests.

          4.2     Liquidated Damages.
                  ------------------

                  4.2.1    If the Delivered Amount of Energy is less than the
                           Supply Amount of Energy in any Dispatch Hour during a
                           month, and Replacement Costs computed in respect of
                           such month are greater than zero, then Supplier shall
                           reimburse Buyer for such Replacement Costs. If
                           Supplier's schedule of Ancillary Services is less
                           than the Supply Amount of Ancillary Services in any
                           Dispatch Hour during a month, Supplier shall
                           reimburse Buyer for such Replacement Costs for the
                           difference between Supplier's schedule and the Supply
                           Amount of Ancillary Services. An example of the
                           methodology used to calculate Replacement Costs is
                           provided in Exhibit D.

                  4.2.2    Supplier also shall be responsible for any costs
                           incurred by Buyer associated with a violation of
                           reliability criteria (including but not limited to
                           imbalance costs or penalties) due to a deviation
                           between the Supply Amount and Delivered Amount.

                  4.2.3    The Parties recognize and agree that the payment of
                           such amounts by Supplier pursuant to this Section 4.2
                           is an appropriate remedy in the event of such a
                           failure and that any such payment does not constitute
                           a forfeiture or penalty of any kind, but rather
                           constitutes actual costs to Buyer under the terms of
                           this Agreement.

         4.3      Supplier Operating Representative. Supplier shall provide and
                  ---------------------------------
                  maintain a twenty-four (24) hour seven (7) day per week
                  communication link with Buyer's control center and with
                  Buyer's schedulers. Supplier's Operating Representatives shall
                  be available to address and make decisions on all operational
                  matters under this Agreement on a twenty-four (24) hour seven
                  (7) day per week basis.

5.       NOTIFICATION

         5.1      Scheduling Notification. Buyer shall provide Supplier with a
                  -----------------------
                  request of the Supply Amount no later than twenty-four (24)
                  hours before day-ahead bids must be submitted to the CALPX.
                  Buyer shall make reasonable efforts to ensure that the request
                  of the Supply Amount is no greater than that amount then
                  projected to be necessary to satisfy Buyer's TRR. In addition,
                  for each Supply Amount request, the change in the Supply
                  Amount from one (1) hour to the next hour shall be no greater
                  than the ramping capability of the units within the Asset
                  Bundle as shown in Exhibit A.

         5.2      Availability Notification.

                           (b)      the magnitude of the Derating;
                           (c)      the hours during which the Derating is
                                    expected to apply;
                           (d)      the cause of the Derating;
                           (e)      the extent, if any, to which the Derating is
                                    attributable to a Permitted Derating; and
                           (f)      the projected Asset Bundle Capacity for each
                                    unit during the period covered by the
                                    Availability Notice, pursuant to Section
                                    5.2.4 below.

                  5.2.5    Neither the Asset Bundle Capacity nor the Supply
                           Amount shall be reduced by Deratings which are not

6.       PRICING OF ENERGY AND ANCILLARY SERVICES

         6.1      Overview. The price of Energy paid by Buyer to Supplier shall
                  --------
                  be based upon a designated hourly market price, subject to
                  monthly floor, monthly ceiling, and annual true-up provisions.
                  The Price Floor of Energy will ensure that Supplier will
                  receive an average price for Energy for each month which is
                  not less than the price stated in Exhibit B. The Price Ceiling
                  of Energy provision provides that the average price of Energy
                  paid to Supplier each month and for each year shall not exceed
                  the price stated in Exhibit B.

                  each month, Supplier shall send to Buyer an invoice setting
                  forth the Supply Amount, Delivered Amount, the Market Price of
                  Energy pursuant to Section 6.2.1 for each Dispatch Hour in the
                  previous month, any amount due in accordance with Section 7.13
                  and the total due from Buyer. The invoice shall be calculated
                  based upon data available to Supplier and shall be in
                  accordance with this Section 7 and Exhibit C. Buyer shall
                  promptly notify Supplier if Buyer in good faith disputes any
                  portion of the invoice, stating in reasonable detail the
                  reason for the dispute.

         7.2      Monthly Invoice Calculation. On each monthly invoice, Supplier
                  ---------------------------
                  shall calculate the following amounts:

                  7.2.1    The Delivered Amount in respect of each Dispatch Hour
                           multiplied by the corresponding Market Price of
                           Energy pursuant to Section 6.2.1, summed over the
                           billing period;

                  7.2.2    Sum of the Delivered Amounts in respect of all
                           Dispatch Hours of the billing period multiplied by
                           the Price Ceiling of Energy;

                  7.2.3    Sum of the Delivered Amounts in respect of all
                           Dispatch Hours of the billing period multiplied by
                           the Price Floor of Energy;

                  7.2.4    For each Dispatch Hour of the billing period, the
                           shortfall, if any, between the Supply Amount and the
                           Delivered Amount (and in the case of Ancillary
                           Services the shortfall between the Supply Amount of
                           Ancillary Services and Supplier's schedule of
                           Ancillary Services);

                  7.2.5    The Supply Amount of Ancillary Service for each
                           dispatch hour multiplied by the price of Ancillary
                           Services as stated in Exhibit B; and

                  7.2.6    The Delivered Amount of Energy related to Ancillary
                           Services for each dispatch hour multiplied by the
                           Price Ceiling of Energy as stated in Exhibit B.

                  7.2.7    If applicable, any amount to be calculated in
                           accordance with Section 7.13.

         7.3      Supplier's Invoice. Supplier will invoice the lesser of the
                  ------------------
                  amounts calculated in Sections 7.2.1 and 7.2.2, provided that
                  if the amount calculated in Section 7.2.1 is less than the
                  amount calculated in Section 7.2.3, Supplier shall invoice
                  Buyer the amount calculated in Section 7.2.3. Supplier shall
                  also include in its invoice the amounts calculated in Sections
                  7.2.5, 7.2.6 and 7.2.7. If the Delivered Amount exceeds the
                  Supply Amount, Buyer shall not be obligated to pay for the
                  excess amount. Buyer shall pay Supplier for the amounts
                  invoiced pursuant to Section 7.2.6 upon Buyer's receipt of
                  payment from ISA or Control Area Operator. Examples of this
                  monthly invoice calculation (and annual true-up process) are

                                       17


                  contained in Exhibit C.

         7.4      Buyer's Invoice. In the event any shortfall occurs pursuant to
                  ---------------
                  Section 7.2.4 or payment is due to Buyer pursuant to Section
                  7.13, Buyer shall within ten (10) Business Days of receipt of
                  Supplier's invoice deliver to Supplier a Buyer's invoice
                  detailing any Replacement Costs or other payment due. Buyer
                  shall provide supporting data in reasonable detail to support
                  its calculations of Replacement Costs. Supplier shall promptly
                  notify Buyer if Supplier in good faith disputes any portion of
                  the invoice, stating in reasonable detail the reason for the
                  dispute. If the Buyer's invoice results in an amount due from
                  Supplier to Buyer, Buyer may offset such amount from its
                  payment of Supplier's corresponding invoice.

                  Buyer shall have the right to adjust the invoices issued in
                  accordance with this Section 7.4 if Buyer incurs Replacement
                  Costs that were not known when earlier invoices were issued.
                  Adjusted invoices shall be issued within thirty (30) days of
                  the date on which the additional Replacement Costs become
                  known. Buyer shall provide supporting data in reasonable
                  detail to support its calculations of Replacement Costs.
                  Supplier shall promptly notify Buyer if Supplier in good faith
                  disputes any portion of the invoice, stating in reasonable
                  detail the reason for the dispute. If the Buyer's adjusted
                  invoice results in an amount due from Supplier to Buyer, Buyer
                  may offset such amount from its payment of Supplier's
                  corresponding invoice.

                  -----------------------------------

                  7.5.1    The annual true-up mechanism will provide adjustments
                           among the Parties with respect to each Contract Year
                           in the following scenarios:

                           (a)      If (i) the Price Ceiling of Energy
                                    multiplied by the hourly Delivered Amount of
                                    Energy summed over the Contract Year is less
                                    than or equal to (ii) the Market Price of
                                    Energy for each hour pursuant to Section
                                    6.2.1 multiplied by the Delivered Amount of
                                    Energy for each hour during the Contract
                                    Year, Supplier shall subtract (x) the amount
                                    invoiced by Supplier for Energy pursuant to
                                    Section 7.3 summed of over the Contract Year
                                    from (y) the Price Ceiling of Energy
                                    multiplied by the hourly Delivered Amount of
                                    Energy summed over the Contract Year. If the
                                    difference calculated in accordance with the
                                    preceding sentence is greater than or equal
                                    to zero, Buyer shall pay the difference to
                                    Supplier. If the difference is less than
                                    zero, Supplier shall refund the difference
                                    to Buyer.

                           (b)      If (i) the Price Ceiling of Energy
                                    multiplied by the hourly Delivered Amount of
                                    Energy summed over the Contract Year is
                                    greater than or equal to (ii) the Market
                                    Price of Energy for each hour pursuant to
                                    Section 6.2.1 multiplied by the Delivered
                                    Amount of Energy for each hour during the
                                    Contract Year, Supplier shall

                                       18


                                    subtract (x) the amount invoiced by Supplier
                                    for Energy pursuant to Section 7.3 summed of
                                    over the Contract Year from (y) the Market
                                    Price of Energy multiplied by the hourly
                                    Delivered Amount of Energy summed over the
                                    Contract Year. If the difference calculated
                                    in accordance with the preceding sentence is
                                    greater than or equal to zero, Buyer shall
                                    pay the difference to Supplier. If the
                                    difference is less than zero, Supplier shall
                                    refund the difference to Buyer.

                           (c)      If Buyer incurred Replacement Costs for
                                    energy during the Contract year, Supplier
                                    shall multiply the Total Amount of Energy
                                    Replaced during the Contract Year by the
                                    Average Cost of Delivered Energy after
                                    true-up as determined in accordance with
                                    Section 7.5.1 (a) or 7.5.1 (b). If the
                                    amount so obtained is greater than the sum
                                    of the monthly Gross Replacement Costs of
                                    Energy from Buyer's Invoices for the
                                    Contract Year, the Adjusted Replacement Cost
                                    of Energy for the Contract Year shall be
                                    zero. If the amount so obtained is less than
                                    the sum of the monthly Gross Replacement
                                    Costs of Energy from Buyer's Invoices for
                                    the Contract Year, the Adjusted Replacement
                                    Cost of Energy for the Contract Year shall
                                    be the sum of the monthly Gross Replacement
                                    Costs of Energy less the amount obtained in
                                    accordance with the first sentence of this
                                    Section 7.5.1(c).

                                    If the Adjusted Replacement Cost of Energy
                                    is greater than the sum of the monthly
                                    Invoiced Replacement Costs of Energy from
                                    Buyer's Invoices for the Contract Year,
                                    Supplier shall pay the difference to Buyer.
                                    If the sum of the monthly Invoiced
                                    Replacement costs of Energy is greater than
                                    the Adjusted Replacement Cost of Energy,
                                    Buyer shall pay the difference to Seller.

                  7.5.2    True-up adjustments will be calculated by Supplier

                  operation of the Asset Bundle and (b) be willing and able to
                  perform its obligations under this Agreement.

10.      INDEMNIFICATION

         10.1  To the fullest extent permitted by law, a Party to this Agreement
               ("the Indemnifying Party") shall indemnify, defend and hold
               harmless the other Party, its parent, affiliates, and successors
               and agents (each an "Indemnified Party") from and against any and
               all claims, demands, suits, obligations, payments, liabilities,
               costs, judgments, damages, losses or expenses asserted by third
               parties against an Indemnified Party and arising out of, relating
               to, or resulting from the Indemnifying Party's breach of, or the
               negligent performance of its obligations under this Agreement.

               10.1.1   Such indemnity shall also extend to actual courts costs,
                        attorneys' fees, expenses and other liabilities incurred
                        in the defense of any claim, action or proceeding,
                        including negotiation, settlement, defense and appeals,
                        to which this indemnification obligation applies. In
                        furtherance of the foregoing indemnification and not by
                        way of limitation thereof, the Indemnifying Party hereby
                        waives any defense it otherwise might have against the
                        Indemnified Party under applicable workers' compensation
                        laws.

               10.1.2   In claims against any Indemnified Party by an agent of
                        the Indemnifying Party, or anyone directly or indirectly
                        employed by them or anyone for whose acts they may be
                        liable, the indemnification obligation under this
                        Section 10 shall not be limited by a limitation on
                        amount or type of damages, compensation or benefits
                        payable by or for the Indemnifying Party or a
                        subcontractor under workers' or workmen's compensation
                        acts, disability benefit acts or other employee benefit
                        acts.

               10.1.3   Such indemnity shall also extend to all costs and
                        expenses incurred by the Indemnified Party in any action
                        or proceeding to enforce the provisions of this
                        Agreement, but only if and to the extent the Indemnified
                        Party prevails in such action or proceeding.

         10.2  No Negation of Existing Indemnities; Survival. Each Party's
               ---------------------------------------------
               indemnity

                                       21


               obligations hereunder shall not be construed to negate, abridge
               or reduce other rights or obligations or indemnity which would
               otherwise exist at law or equity. The obligations contained
               herein shall survive any termination, cancellation, or suspension
               of this Agreement to the extent that any third party claim is
               commenced during the applicable statute of limitations period.

          10.3 Indemnification Procedures.
               --------------------------

               10.3.1   Any Party seeking indemnification under this Agreement
                        shall give the other Party notice of such claim promptly
                        but in any event on or before thirty (30) days after the
                        Party's actual knowledge of such claim or action. Such
                        notice shall describe the claim in reasonable detail,
                        and shall indicate the amount (estimated if necessary)
                        of the claim that has been, or may be sustained by, said
                        Party. To the extent that the other Party will have been
                        actually and materially prejudiced as a result of the
                        failure to provide such notice, such notice will be a
                        condition precedent to any liability of the other Party
                        under the provisions for indemnification contained in
                        this Agreement.

               10.3.2   In any action or proceeding brought against an
                        Indemnified Party by reason of any claim indemnifiable
                        hereunder, the Indemnifying Party may, at its sole
                        option, elect to assume the defense at the Indemnifying
                        Party's expense, and shall have the right to control the
                        defense thereof and to determine the settlement or
                        compromise of any such action or proceeding.
                        Notwithstanding the foregoing, an Indemnified Party
                        shall in all cases be entitled to control its defense in
                        any action if it:

                        (i)   may result in injunctions or other equitable
                              remedies in respect of the Indemnified Party which
                              would affect its business or operations in any
                              materially adverse manner;

                        (ii)  may result in material liabilities which may not
                              be fully indemnified hereunder; or

                        (iii) may have a significant adverse impact on the
                              business or the financial condition of the
                              Indemnified Party (including a material adverse
                              effect on the tax liabilities, earnings or ongoing
                              business relationships of the Indemnified Party)
                              even if the Indemnifying Party pays all
                              indemnification amounts in full.

               10.3.3   Subject to Section 10.3.2, neither Party may settle or
                        compromise any claim for which indemnification is sought
                        under this Agreement without the prior consent of the
                        other Party; provided, however, said consent shall not
                        be unreasonably withheld or delayed.

11.      LIMITATION OF LIABILITY

                                       22


         11.1     Responsibility for Damages: Except as otherwise provided
                  --------------------------
                  herein or to the extent of the other Party's negligence or
                  willful misconduct, each Party shall be responsible for all
                  physical damage to or destruction of the property, equipment
                  and/or facilities owned by it and its affiliates and any
                  physical injury or death to natural Persons resulting
                  therefrom, regardless of who brings the claim and regardless
                  of who caused the damage, and shall not seek recovery or
                  reimbursement from the other Party for such damage; provided,
                  that in any such case the Parties will exercise Due Diligence
                  to remove the cause of any disability at the earliest
                  practicable time.

         11.2     No Consequential Damages: To the fullest extent permitted by
                  ------------------------
                  law and notwithstanding other provisions of this Agreement, in
                  no event shall a Party, or any of its Agents, be liable to the
                  other Party, whether in contract, warranty, tort, negligence,
                  strict liability, or otherwise, for special, indirect,
                  incidental, multiple, consequential (including but not limited
                  to lost profits or revenues and lost business opportunities),
                  or punitive damages related to or resulting from performance
                  or nonperformance of this Agreement or any activity associated
                  with or arising out of this Agreement. For purposes of
                  clarification, Replacement Costs shall not be considered
                  consequential or incidental damages under this Section 11.2.
                  In addition, this limitation on liability shall not apply with
                  respect to claims pursuant to Section 10 hereof.

         11.3     Survival: The provisions of this Section 11 shall survive any
                  --------
                  termination, cancellation, or suspension of this Agreement.

12.      FORCE MAJEURE

         12.1     An event of "Force Majeure" shall be defined as any
                  interruption or failure of service or deficiency in the
                  quality or quantity of service or any other failure to perform
                  any of its obligations hereunder to the extent such failure
                  occurs without fault or negligence on the part of that Party
                  and is caused by factors beyond that Party's reasonable
                  control, which by the exercise of reasonable diligence that
                  Party is unable to prevent, avoid, mitigate or overcome,
                  including:

                  (i)   acts of God or the public enemy, such as storms,
                        flood, lightning, and earthquakes,

                  (ii)  failure, threat of failure, or unscheduled withdrawal
                        of facilities from operation for maintenance or
                        repair, and including unscheduled transmission and
                        distribution outages,

                  (iii) sabotage of facilities and equipment,

                  (iv)  civil disturbance,

                  (v)   strike or labor dispute,

                  (vi)  action or inaction of a court or public authority, or

                                       23


                  (vii) any other cause of similar nature beyond the
                        reasonable control of that Party.

         12.2     Economic hardship of either Party shall not constitute Force
                  Majeure under this Agreement. Notwithstanding this, if Buyer
                  suffers an event of Force Majeure it shall be relieved of its
                  obligation to take delivery of, or otherwise pay for, Energy
                  and Ancillary Services under this Agreement for the duration
                  of the event of Force Majeure. In addition, if Buyer is unable
                  to have Energy and Ancillary Services delivered from the
                  Point(s) of Delivery to its service territory due to an outage
                  on the Transmission System, that shall be considered a Force
                  Majeure event and shall relieve Buyer of performance for the
                  extent of the event.

         12.3     In the event of a Force Majeure, neither Party shall be
                  considered in default under this Agreement or responsible to
                  the other Party in tort, strict liability, contract or other
                  legal theory for damages of any description, and affected
                  performance obligations shall be extended by a period equal to
                  the term of the resultant delay, but in no event shall exceed
                  the term of the Agreement, provided that the Party relying on
                  a claim of Force Majeure:

                  (i)   provides prompt written notice of such Force Majeure
                        event to the other Party, giving an estimate of its
                        expected duration and the probable impact on the
                        performance of its obligations hereunder;

                  (ii)  exercises all reasonable efforts to continue to
                        perform its obligations under this Agreement;

                  (iii) expeditiously takes action to correct or cure the
                        event or condition excusing performance so that the
                        suspension of performance is no greater in scope and
                        no longer in duration than is dictated by the
                        problem; provided, however, that settlement of
                        strikes or other labor disputes will be completely
                        within the sole discretion of the Party affected by
                        such strike or labor dispute;

                  (iv)  exercises all reasonable efforts to mitigate or limit
                        damages to the other Party; and

                  (v)   provides prompt notice to the other Party of the
                        cessation of the event or condition giving rise to
                        its excuse from performance.

         12.4     Notwithstanding the above provisions, a Force Majeure event
                  shall excuse Supplier from its obligation to deliver the
                  Supply Amount pursuant to Section 4 of this Agreement only for
                  the first forty-eight (48) hours of the Force Majeure event.
                  After such forty-eight (48) hour period, Supplier must either
                  deliver the Supply Amount at the Point(s) of Delivery or pay
                  liquidated damages pursuant to Section 4.2 of this Agreement.
                  Provided that, to the extent a Force Majeure event is caused
                  by an outage on the Transmission System, Supplier shall be
                  excused

                                       24


                  from its obligations to deliver the Supply Amount for the
                  duration of the outage.

         12.5     If Supplier has notified Buyer of an event of Force Majeure,
                  and if Supplier so requests, Buyer will attempt to replace the
                  Supply Amount that is not excused in accordance with Section
                  12.4 with Energy or Ancillary Services from another Asset
                  Bundle. However, Buyer's inability to acquire such replacement
                  Energy or Ancillary Services shall not excuse Supplier from
                  Supplier's obligation to deliver the Supply Amount not
                  otherwise excused in accordance with Section 12.4

13.      DISPUTES

         13.1     Any action, claim or dispute which either Party may have
                  against the other arising out of or relating to this Agreement
                  or the transactions contemplated hereunder, or the breach,
                  termination or validity thereof (any such claim or dispute, a
                  "Dispute") shall be submitted in writing to the other Party.
                  The written submission of any Dispute shall include a concise
                  statement of the question or issue in dispute together with a
                  statement listing the relevant facts and documentation that
                  support the claim.

         13.2     The Parties agree to cooperate in good faith to expedite the
                  resolution of any Dispute. Pending resolution of a Dispute,
                  the Parties shall proceed diligently with the performance of
                  their obligations under this Agreement.

         13.3     The Parties shall first attempt in good faith to resolve any
                  Dispute through informal negotiations by the Contract
                  Representatives. In the event that the Contract
                  Representatives are unable to satisfactorily resolve the
                  Dispute within thirty (30) days from the receipt of notice of
                  the Dispute, either Party may by written notice to the other
                  Party refer the Dispute to its respective senior management
                  for resolution as promptly as practicable. If the Parties'
                  senior management are unable to resolve the Dispute within
                  forty-five (45) days from the date of such referral,
                  thereafter the Parties may agree in writing to extend the time
                  period of such senior management negotiations. In the event
                  the Parties' senior management do not resolve the dispute
                  within the prescribed or extended time period, either Party
                  may initiate arbitration through the serving and filing of a
                  demand for arbitration and the Parties expressly agree that
                  arbitration in accordance with this Section 13 shall be the
                  exclusive means to further resolve any Dispute and hereby
                  irrevocably waive their right to a jury trial with respect to
                  any Dispute, provided that at any time:

                  13.3.1   A request made by a Party for provisional remedies
                           requesting preservation of the Parties' respective
                           rights and obligations under the Agreement may be
                           resolved by a court of law located in the County of
                           the principal place of business of Buyer.

                  13.3.2   Nothing in this Agreement shall preclude, or be
                           construed to preclude, any Party from filing a
                           petition or complaint with the FERC or PUCN with
                           respect to any arbitrable Dispute over which said
                           agency has jurisdiction. In such case, the other
                           Party may request the FERC or

                                       25


                           PUCN, as applicable, to reject or to waive
                           jurisdiction. If jurisdiction is rejected or waived
                           with respect to all or a portion of the Dispute, the
                           portion of the Dispute not so accepted by the FERC or
                           PUCN, as applicable, shall be resolved through
                           arbitration in accordance with this Agreement. To the
                           extent that the FERC or PUCN, as applicable, asserts
                           or accepts jurisdiction over the Dispute, the
                           decision, finding of fact or order of FERC shall be
                           final and binding, subject to judicial review under
                           the Federal Power Act or Nevada Revised Statutes and
                           subject to the provisions of Section 2.2.2. Any
                           arbitration proceedings that may have commenced with
                           respect to the Dispute prior to the assertion or
                           acceptance of jurisdiction by the FERC or PUCN, as
                           applicable, shall be terminated to the extent the
                           FERC or PUCN accepts or asserts jurisdiction over
                           such Dispute.

         13.4     Unless otherwise agreed by the Parties, any arbitration
                  initiated under this Agreement shall be conducted in
                  accordance with the following:

                  13.4.1   Arbitrations shall be held within the County of the
                           principal place of business of Buyer.

                  13.4.2   Except as otherwise modified herein, the arbitration
                           shall be conducted in accordance with the "Commercial
                           Arbitration Rules" of the American Arbitration
                           Association ("AAA") then in effect.

                  13.4.3   Arbitration shall be conducted by one neutral
                           arbitrator who shall be selected pursuant to the AAA
                           rules and the following:

                           13.4.3.1 The Parties agree that the list of potential
                                    arbitrators provided by the AAA shall, if
                                    available, contain twenty (20) candidates,
                                    and at least fifty percent (50%) of the
                                    candidates shall be members of the AAA
                                    National Energy Panel.

                           13.4.3.2 The Parties also agree that each shall be
                                    allowed to strike the names of five
                                    candidates before ranking the remaining
                                    candidates and returning the list to the AAA
                                    in accordance with the Commercial
                                    Arbitration Rules. If the Parties are unable
                                    to agree on an arbitrator, such arbitrator
                                    shall be appointed by the AAA.

                           13.4.3.3 The arbitrator shall not have any current or
                                    past substantial business, financial, or
                                    personal relationships with either Party (or
                                    their Affiliates) and shall not be a vendor,
                                    supplier, customer, employee, consultant, or
                                    competitor to either of the Parties or their
                                    Affiliates.

                           13.4.3.4 The arbitrator shall be authorized only to
                                    interpret and apply the provisions of this
                                    Agreement or any related agreements entered
                                    into under this Agreement and shall

                                       26


                                    have no power to modify or change any
                                    provision of this Agreement. The arbitrator
                                    shall have no authority to award punitive or
                                    multiple damages or any damages inconsistent
                                    with this Agreement. The arbitrator shall
                                    within thirty (30) days of the conclusion of
                                    the hearing, unless such time is extended by
                                    agreement of the Parties, notify the Parties
                                    in writing of his or her decision, stating
                                    his or her reasons for such decision and
                                    separately listing his or her findings of
                                    fact and conclusions of law. Judgment on the
                                    award may be entered in any court having
                                    jurisdiction.

         13.5     The Parties shall proceed with the arbitration expeditiously,
                  and the arbitration shall be concluded within five (5) months
                  of the filing of the demand for arbitration pursuant to this
                  Section 13 in order that the decision may be rendered within
                  six (6) months of such filing, unless the arbitrator extends
                  such time at the request of a Party upon a showing of good
                  cause or upon agreement of the Parties.

         13.6     Any arbitration proceedings, decision or award rendered
                  hereunder and the validity, effect and interpretation of any
                  arbitration agreement shall be governed by the Federal
                  Arbitration Act of the United States, 9 U.S.C. ss.ss. 1 et
                  seq.

         13.7     The decision of the arbitrator shall be final and binding on
                  both Parties and may be enforced in any court having
                  jurisdiction over the Party against which enforcement is
                  sought.

         13.8     The fees and expenses of the arbitrator shall be shared by the
                  Parties equally, unless the decision of the arbitrator shall
                  specify some other apportionment of such fees and expenses.
                  All other expenses and costs of the arbitration shall be borne
                  by the Party incurring the same.

14.      NATURE OF OBLIGATIONS

         14.1     Except where specifically stated in this Agreement to be
                  otherwise, the duties, obligations, and liabilities of the
                  Parties shall be several; not joint or collective. The
                  provisions of this Agreement shall not be construed to create
                  an association, trust, partnership, or joint venture; to
                  impose a trust or partnership duty, obligation, or liability
                  or agency relationship on or with regard to either Party.

         14.2     Nothing in this Agreement nor any action taken hereunder shall
                  be construed to create any duty, liability, or standard of
                  care to any person not a Party to this Agreement. Each Party
                  shall be individually and severally liable for its own
                  obligations under this Agreement.

         14.3     By this Agreement, neither Party dedicates any part of its
                  facilities or the service provided under this Agreement to the
                  public.

15.      SUCCESSORS AND ASSIGNS

                                       27


         15.1     This Agreement may be assigned, without express written
                  consent of the other Party, as follows:

                  15.1.1   Buyer may assign this Agreement or assign or delegate
                           its rights and obligations under this Agreement, in
                           whole or in part, if such assignment is made to an
                           affiliate, parent, subsidiary, successor or any
                           party, provided that such assignee operates all or a
                           portion of the PLR or if such assignment is required
                           by Law or applicable regulations.

                  15.1.2   Supplier also may assign this Agreement as provided
                           in Section 11.5 of the Asset Sale Agreement; provided
                           that such assignment is to an entity that (a) has the
                           right to control the operation of the Asset Bundle
                           and (b) is willing and able to perform its
                           obligations under this Agreement.

         15.2     Supplier may, without the consent of Buyer, assign, transfer,
                  pledge or otherwise dispose of its rights and interests
                  hereunder to a trustee, lending institution, or any Person for
                  the purposes of financing or refinancing the Asset Bundle,
                  including upon or pursuant to the exercise of remedies under
                  such financing or refinancing, or by way of assignments,
                  transfers, conveyances of dispositions in lieu thereof;
                  provided, however, that no such assignment or disposition
                  shall relieve or in any way discharge Supplier or such
                  permitted assignee from the performance of its duties and
                  obligations under this Agreement. Buyer agrees to execute and
                  deliver such documents as may be reasonably necessary to
                  accomplish any such assignment, transfer, conveyance, pledge
                  or disposition of rights hereunder for purposes of the
                  financing or refinancing of the Asset Bundle, so long as
                  Buyer's rights under this Agreement are not thereby materially
                  altered, amended, diminished or otherwise impaired.

         15.3     Either Party may, without the consent of the other Party,
                  assign this Agreement to a successor to all or substantially
                  all of the assets of such Party by way of merger,
                  consolidation, sale or otherwise, provided such successor
                  assumes and becomes liable for all of such Party's duties and
                  obligations hereunder including Section 3 hereof.

         15.4     Except as stated above, neither this Agreement nor any of the
                  rights, interests, or obligations hereunder shall be assigned
                  by either Party, including by operation of law, without the
                  prior written consent of the other Party, said consent not to
                  be unreasonably withheld. Any assignment of this Agreement in
                  violation of the foregoing shall be, at the option of the
                  non-assigning Party, void.

         15.5     Except as set forth above, no assignment or transfer of rights
                  or obligations under this Agreement by a Party shall relieve
                  said Party from full liability and financial responsibility
                  for the performance thereof after any such transfer or
                  assignment unless and until the transferee or assignee shall
                  agree in writing to assume the obligations and duties of said
                  Party under this Agreement and the other Party has consented
                  in writing to such assumption; said consent not to be
                  unreasonably withheld.

                                       28


         15.6     This Agreement and all of the provisions hereof are binding
                  upon, and inure to the benefit of, the Parties and their
                  respective successors and permitted assigns.

16.      REPRESENTATIONS

         16.1     Representations of the Parties. The Parties represent and
                  ------------------------------
                  warrant each to the other as follows:

                  16.1.1   Incorporation. Buyer is a corporation duly
                           -------------
                           incorporated, validly existing and in good standing
                           under the laws of the State of Nevada. Supplier is a
                           limited liability company duly organized, validly
                           existing and in good standing under the laws of the
                           State of Delaware. Both Buyer and Supplier have all
                           requisite corporate power and authority to own, lease
                           and operate their material assets and properties and
                           to carry on their business as now being conducted.

                  16.1.2   Authority. The Party has full corporate power and
                           ---------
                           authority to execute and deliver this Agreement and,
                           subject to the procurement of applicable regulatory
                           approvals, to carry out the actions required of it by
                           this Agreement. The execution and delivery of this
                           Agreement and the transactions contemplated hereby
                           have been duly and validly authorized by all
                           necessary corporate action required on the part of
                           the Party. The Agreement has been duly and validly
                           executed and delivered by the Party and, assuming
                           that it is duly and validly executed and delivered by
                           the other Party, constitutes a legal, valid and
                           binding agreement of the Party.

                  16.1.3   Compliance With Law. The Party represents and
                           -------------------
                           warrants that it is not in violation of any
                           applicable Law, or applicable regulation, which
                           violation could reasonably be expected to materially
                           adversely affect the other Party's performance of its
                           obligations under this Agreement. The Party
                           represents and warrants that it will comply with all
                           Laws, and regulations applicable to its compliance
                           with this Agreement, non-compliance with which would
                           reasonably be expected to materially adversely affect
                           either Party's performance of its obligations under
                           this Agreement.

                  16.1.4   Representations of Both Parties. The representations
                           -------------------------------
                           in this Section 16 shall continue in full force and
                           effect for the term of this Agreement.

17.      DEFAULT AND REMEDIES

         17.1     An Event of Default hereunder shall be deemed to have occurred
                  upon a Party's (Defaulting Party) failure to comply with any
                  material obligation imposed upon it by this Agreement.
                  Examples of an Event of Default include, but are not limited
                  to the following:

                  (i)      Failure to make any payments due under this
                           Agreement;

                                       29


                  (ii)     Failure to deliver the Supply Amount for a period of
                           five (5) consecutive days;

                  (iii)    Failure to follow the directions of a Control Area
                           Operator, ISA, EDU, WSCC, NERC, PUCN, FERC, or any
                           successor thereto where following such directions is
                           required hereunder;

                  (iv)     Supplier not being in compliance with Section 3; and

                  (v)      Failure of the Guarantor to be in compliance with the
                           terms of the Guarantee delivered under Section 3.1.2.

         17.2     An Event of Default shall be excused:

                  17.2.1   In the event such Event of Default was caused by
                           Force Majeure provided that the Party claiming a
                           Force Majeure complies with the requirements of
                           Section 12; and

                  17.2.2   In the event such Event of Default was caused by
                           transmission and distribution outages or disruptions.

         17.3     Unless excused, in an Event of Default the Non-Defaulting
                  Party shall be entitled to provide written notice (or verbal
                  notice in case of emergency followed by written notice) of the
                  Event of Default to the Defaulting Party and to specify a cure
                  period, which cure period shall be a minimum of thirty (30)
                  days.

         17.4     If an Event of Default is not cured by the Defaulting Party
                  during the cure period specified by the Non-Defaulting Party,
                  the Non-Defaulting Party shall be entitled to those remedies
                  which are not inconsistent with the terms of this Agreement,
                  including termination and the payment of liquidated damages. A
                  Defaulting Party shall not be liable to the Non-Defaulting
                  Party for any punitive, consequential or incidental damages.
                  For purposes of clarification, Replacement Costs shall not be
                  considered consequential or incidental damages under this
                  Section 17.4.

         17.5     Notwithstanding this Section 17, liquidated damages shall be
                  paid to Buyer pursuant to Sections 4.2, 12, 18, and 21.

18.      FACILITY ADDITIONS AND MODIFICATIONS

         18.1     Supplier shall be entitled to make additions and modifications
                  to the Asset Bundle subject to the following:

                  18.1.1   To the extent additions and modifications interfere
                           with the operation of the Asset Bundle in providing
                           the Supply Amount to Buyer beyond the limits for
                           planned outages set forth in Section 21, liquidated
                           damages shall be paid to Buyer pursuant to Section
                           4.2.

                  18.1.2   Supplier shall use reasonable efforts to minimize any
                           adverse impact on

                                       30


                           Buyer during the course of making such additions and
                           modifications.

                  18.1.3   Such additions and modifications shall be conducted
                           in accordance with Good Utility Practice, and all
                           applicable Laws, regulations, reliability criteria
                           and the Interconnection Agreement between Buyer and
                           Supplier, dated November 16, 2000, as it may be
                           amended from time to time.

         18.2     Supplier shall seek Buyer's prior written approval for all
                  Supplier's additions or modifications to the Asset Bundle
                  which might reasonably be expected to have an adverse effect
                  upon Buyer with respect to operations or performance under
                  this Agreement.

19.      COORDINATION

         19.1     Upon knowledge thereof, each Party shall promptly give notice
                  to the other Party of any labor dispute which is delaying or
                  threatens to delay the timely performance of this Agreement,
                  which shall include a description of the general nature of the
                  dispute.

20.      EMERGENCY AND NONEMERGENCY CONDITION RESPONSE

         20.1     Buyer and Supplier shall comply with any applicable
                  requirement of any Governmental Authority, NERC, WSCC, ISA,
                  Control Area Operator, transmission operator, EDU or any
                  successor of any of them, regarding the reduced or increased
                  generation of the Asset Bundle in the event of an Emergency
                  Condition or Nonemergency Condition.

         20.2     Supplier shall not be obligated to deliver the Supply Amount
                  and no liquidated damages shall become due, if the Supply
                  Amount is reduced in the event of an Emergency Condition or a
                  Nonemergency Condition.

         20.3     Each Party shall provide prompt verbal notice to the other
                  Party of any Emergency Condition or Nonemergency Condition.

         20.4     Either Party may take reasonable and necessary action to
                  prevent, avoid or mitigate injury, danger, damage or loss to
                  its own equipment and facilities, or to expedite restoration
                  of service; provided, however, that the Party taking such
                  action shall give the other Party prior notice if at all
                  possible before taking any action. However, this Section 20.4
                  shall not be construed to supersede Sections 20.2 and 20.3.

21.      OUTAGE SCHEDULING

         21.1     Supplier shall request Buyer's approval prior to any
                  inspections, proposed planned outages or other non-forced
                  outages (all hereinafter referred to as "planned outages") of
                  the Asset Bundle so as to minimize the impact on the
                  availability of the Asset Bundle. Under no circumstances shall
                  Supplier conduct a

                                       31


                  planned outage without the express prior consent of Buyer
                  pursuant to this Section 21.

         21.2     Planned Outages.
                  ---------------

                  21.2.1   Within sixty (60) days following the Effective Date
                           of this Agreement and on or before October 1 of each
                           Contract Year, Supplier shall provide Buyer with a
                           schedule of proposed planned outages for the period
                           beginning on the date of such proposed schedule for
                           the following twelve (12) months. The proposed
                           planned outage schedule will designate days for each
                           unit in which the Asset Bundle Capacity will be
                           reduced in part or total for each such unit. Each
                           proposed schedule shall include all applicable
                           information, including but not limited to the
                           following: Month, day and time of requested outage;
                           facilities impacted (such as Unit and description);
                           duration of outage; purpose of outage; amount of
                           capacity (in MWs) which is derated; other conditions
                           and remarks; and name of contact and phone number.

                  21.2.2   Buyer shall promptly review Supplier's proposed
                           schedule and shall either require modifications or
                           approve the proposed schedule. Supplier shall use its
                           best efforts to accomplish all planned outages in
                           accordance with the approved schedule. Supplier shall
                           be responsible to Buyer for Replacement Costs (i) if
                           any outage period exceeds its approved schedule,
                           provided that changes to the approved schedule may be
                           requested by either Party and each Party shall make
                           reasonable efforts to accommodate such changes,
                           provided further the Buyer shall have no obligation
                           to agree to Supplier's revisions to the approved
                           planned outage schedule; and (ii) if Supplier
                           conducts a planned outage without the consent of
                           Buyer as provided herein.

22.      REPORTS

         22.1     Supplier shall promptly provide Buyer with copies of any
                  orders, decrees, letters or other written communications to or
                  from any Governmental Authority asserting or indicating that
                  Supplier and/or its Asset Bundle is in violation of Laws which
                  relate to Supplier, or operations or maintenance of the Asset
                  Bundle and which may have an adverse effect on Buyer. Supplier
                  shall use reasonable efforts to keep Buyer appraised of the
                  status of any such matters.

23.      COMMUNICATIONS

                           Buyer and the Control Area Operator.

         23.3     Supplier shall immediately report to Buyer any "Abnormal
                  Condition" that has or may occur, and provide all pertinent
                  information, including but not limited to the following:

         23.4     Cause of the Condition.
                  ----------------------

                  23.4.1   An "Abnormal Condition" shall include without
                           limitation any conditions that, to Supplier's
                           knowledge, have or are reasonably likely to:

                           (i)     Adversely affect Supplier's ability to
                                   provide Energy and Ancillary Services to
                                   Buyer;

                  remaining terms, provisions and conditions of this Agreement
                  shall continue in full force and effect, unless, however, the
                  effect of the severance would vitiate the intent of the
                  Parties hereto, as determined by either Party in its
                  reasonable discretion.

         28.2     The Parties shall endeavor in good faith to replace such
                  invalid, void, or unenforceable provisions with a valid and
                  enforceable provision which achieves the purposes intended by
                  the Parties to the greatest extent permitted by law.

29.      WAIVERS

         29.1     No failure or delay on the part of a Party in exercising any
                  of its rights under this Agreement or in insisting upon strict
                  performance of provisions of this Agreement, no partial
                  exercise by either Party of any of its rights under this
                  Agreement, and no course of dealing between the Parties shall
                  constitute a waiver of the rights of either Party under this
                  Agreement. Any waiver shall be effective only by a written
                  instrument signed by the Party granting such waiver, and such
                  shall not operate as a waiver of, or estoppel with respect to,
                  any subsequent failure to comply therewith.

30.      AMENDMENTS

         30.1     The Parties shall negotiate in good faith to determine
                  necessary amendments, if any, to this Agreement, provided that
                  in negotiating such amendments the Parties shall attempt, in
                  good faith, to reasonably preserve the bargain initially
                  struck in this Agreement if any Governmental Authority, FERC,
                  any state or the PUCN, implements a change in any Law or
                  applicable regulation that materially affects or is reasonably
                  expected to materially affect Buyer's PLR service under this
                  Agreement.

         30.2     The Parties shall meet to discuss the impact of any changes in
                  Buyer's OATT or the ISA's OATT, as applicable, or any rule or
                  practice of NERC, WSCC, or any other Governmental Authority on
                  the terms of this Agreement upon request by either Party
                  during the term of this Agreement.

         30.3     In the event that it is deemed necessary to amend this
                  Agreement, the Parties will attempt to agree upon such
                  amendment and will submit such mutually agreed upon
                  amendment(s) to the FERC for filing and acceptance.

                                       35


         30.4     Amendments to this Agreement shall be in writing and shall be
                  executed by an authorized representative of each Party.

31.      TIME IS OF THE ESSENCE

         31.1     Time is of the essence of this Agreement and in the
                  performance of all of the covenants and conditions hereof.

32.      APPROVALS

         32.1     Each Party's performance under this Agreement is subject to
                  the condition that all requisite governmental and regulatory
                  approvals for such performance are obtained in form and
                  substance satisfactory to the other Party in its reasonable
                  discretion. Each Party shall use best efforts to obtain all
                  required approvals and shall exercise due diligence and shall
                  act in good faith to cooperate and assist each other in
                  acquiring any regulatory approval necessary to effectuate this
                  Agreement. Further, the Parties agree to reasonably support
                  the other Party in any associated regulatory proceedings,
                  including by being a witness on behalf of the other Party.

         32.2     Notwithstanding the provisions of Section 2.2.2 of this
                  Agreement, if any Governmental Authority in its review of the
                  Agreement places conditions on or requires revisions of the
                  Agreement that have no more than a de minimus effect on
                  Supplier or Buyer, the Parties agree to execute an amendment
                  to this Agreement reasonably acceptable to each Party
                  incorporating such conditions or revisions.

         32.3     This Agreement is made subject to present or future state or
                  federal laws, regulations, or orders properly issued by state
                  or federal bodies having jurisdiction.

         32.4     The Parties hereto agree to execute and deliver promptly, at
                  the expense of the Party requesting such action, any and all
                  other and further instruments, documents and information which
                  may reasonably be necessary or appropriate to give full force
                  and effect to the terms and intent of this Agreement.

33.      PLR SERVICE

         33.1     The Agreement is premised on Buyer providing PLR service.
                  Notwithstanding anything to the contrary contained herein, if
                  Nevada retail electricity restructuring (including
                  implementation of retail customer choice of electricity
                  suppliers) is delayed beyond the Effective Date of this
                  Agreement, the Parties shall continue to perform this
                  Agreement in all respects pursuant to the terms and conditions
                  hereof as if Buyer was the PLR and Buyer's retail and
                  wholesale customers shall be considered as the TRR.

                                       36


34.      CONFIDENTIALITY

         34.1     Confidential Information. Certain information provided by a
                  ------------------------
                  Party (the "Disclosing Party") to the other Party (the
                  "Receiving Party") in connection with the negotiation or
                  performance of this Agreement may be considered confidential
                  and/or proprietary (hereinafter referred to as "Confidential
                  Information") by the Disclosing Party. To be considered
                  Confidential Information hereunder, such information must be
                  clearly labeled or designated by the Disclosing Party as
                  "confidential" or "proprietary" or with words of like meaning.
                  If disclosed orally, such information shall be clearly
                  identified as confidential and such status shall be confirmed
                  promptly thereafter in writing.

         34.2     Treatment of Confidential Information. The Receiving Party
                  -------------------------------------
                  shall treat any Confidential Information with at least the
                  same degree of care regarding its secrecy and confidentiality
                  as the Receiving Party's similar information is treated within
                  the Receiving Party's organization. The Receiving Party shall
                  not disclose the Confidential Information of the Disclosing
                  Party to third parties (except as stated hereinafter) nor use
                  it for any purpose other than the negotiation or performance
                  of this Agreement, without the express prior written consent
                  of the Disclosing Party. The Receiving Party further agrees
                  that it shall restrict disclosure of Confidential Information
                  as follows:

                  34.2.1   Disclosure shall be restricted solely to its agents
                           as may be necessary to enforce the terms of this
                           Agreement after advising those agents of their
                           obligations under this Section 34.2.

                  34.2.2   In the event that the Receiving Party is requested,
                           pursuant to or as required by applicable Law or by
                           legal process, to disclose any Confidential
                           Information, the Receiving Party shall provide the
                           Disclosing Party with prompt notice of such request
                           or requirement in order to enable Disclosing Party to
                           seek an appropriate protective order or other remedy
                           and to consult with Disclosing Party with respect to
                           Disclosing Party taking steps to resist or narrow the
                           scope of such request or legal process. The Receiving
                           Party agrees not to oppose any action by the
                           Disclosing Party to obtain a protective order or
                           other appropriate remedy. In the absence of such
                           protective order, and provided that the Receiving
                           Party is advised by its counsel that it is compelled
                           to disclose the Confidential Information, the
                           Receiving Party shall:

                           (i)      furnish only that portion of the
                                    Confidential Information which the Receiving
                                    Party is advised by counsel is legally
                                    required; and

                           (ii)     use its commercially reasonable best
                                    efforts, at the expense of the Disclosing
                                    Party, to ensure that all Confidential
                                    Information so disclosed will be accorded
                                    confidential treatment.

         34.3     Excluded Information. Confidential Information shall not be
                  --------------------
                  deemed to include

                                       37


                  the following:

                  34.3.1   information which is or becomes generally available
                           to the public other than as a result of a disclosure
                           by the Receiving Party;

                  34.3.2   information which was available to the Receiving
                           Party on a non-confidential basis prior to its
                           disclosures by the Disclosing Party; and

                  34.3.3   information which becomes available to the Receiving
                           Party on a non-confidential basis from a person other
                           than the Disclosing Party or its representative who
                           is not otherwise bound by a confidentiality agreement
                           with Disclosing Party or its agent or is otherwise
                           not under any obligation to Disclosing party or its
                           agent not to disclose the information to the
                           Receiving Party.

         34.4     Injunctive Relief Due to Breach. The Parties agree that
                  -------------------------------
                  remedies at law may be inadequate to protect each other in the
                  event of a breach of this Section 34, and the Receiving Party
                  hereby in advance agrees that the Disclosing Party shall be
                  entitled to seek and obtain, without proof of actual damages,
                  temporary, preliminary and permanent injunctive relief from
                  any court or Governmental Authority of competent jurisdiction
                  restraining the Receiving Party from committing or continuing
                  any breach of this Section 34.

35.      CHOICE OF LAW

         35.1     This Agreement and the rights and obligations of the Parties
                  shall be construed and governed by the Laws of: (i) the State
                  of Nevada as if executed and performed wholly within that
                  state; and (ii) the Federal Power Act, to the extent the
                  rights and obligations of the Parties are covered by such act.

                                    EXHIBIT H
                                FORM OF GUARANTEE

         This Guarantee is entered into as of November 16, 2000 by NRG Energy,
Inc., a Delaware corporation, and Dynegy Holdings Inc., a Delaware corporation
(each, a "Guarantor"), on behalf of Reid Gardner Power LLC, a Delaware limited
liability company ("Supplier"), in favor of and for the benefit of Nevada Power
Company, a Nevada corporation ("NPC"). NPC is sometimes referred to herein as
"Beneficiary".

         WHEREAS, Supplier and NPC are entering into a Transitional Power
Purchase Agreement dated as of November 16, 2000 (the "TPPA") by which Supplier
has agreed to sell and NPC has agreed to buy Energy and Ancillary Services (as
defined in the TPPA) produced by the Reid Gardner generating station being sold
by NPC; and

         WHEREAS, it is a condition to the obligation of NPC to enter into the
TPPA for Guarantor to guarantee the Supplier's obligations under the TPPA in an
amount not to exceed the Credit Amount (as defined in the TPPA) (the "Guarantied
Obligations").

         1. Guarantee. Each Guarantor jointly and severally, and irrevocably and
unconditionally, guaranties, as primary obligor and not merely as surety, the
due and punctual payment in full of all Guarantied Obligations (including
amounts that would become due but for the operation of the automatic stay under
Section 362(a) of the Bankruptcy Code, 11 U.S.C.(S)362(a)).

         In the event that all or any portion of the Guarantied Obligations is
paid by Supplier, the obligations of Guarantor hereunder shall continue and
remain in full force and effect or be reinstated, as the case may be, in the
event that all or any part of such payment(s) is rescinded or recovered directly
or indirectly from the Beneficiary as a preference, fraudulent transfer or
otherwise, and any such payments that are so rescinded or recovered shall
constitute Guarantied Obligations (to the extent such payments, in the
aggregate, do not exceed the Credit Amount).

         Subject to the other provisions of this Section 1, upon failure of
Supplier to pay any of the Guarantied Obligations when and as the same shall
become due, the Guarantors will upon demand pay, or cause to be paid, in cash,
to NPC, an amount equal to the aggregate of the unpaid Guarantied Obligations to
the extent due. In the event the Guarantors fail to pay the Guarantied
Obligations, each and every default in the payment shall give rise to a separate
cause of action and separate causes of action may be brought hereunder as each
such cause of action arises. In no event shall the amount recoverable hereunder
by Beneficiary from the Guarantors, singly or jointly, ever exceed the Credit
Amount (as defined in the TPPA).

         2. Expenses. Each Guarantor agrees to reimburse NPC for all reasonable
costs and expenses (including, without limitation, the reasonable fees and
expenses of legal counsel) in connection with (i) any default by such Guarantor
hereunder and any enforcement or collection proceeding resulting therefrom,
including, without limitation, all manner of participation in or other
involvement with bankruptcy, insolvency, receivership, foreclosure, winding up
or liquidation proceedings of or involving the Guarantor, judicial or regulatory
proceedings of or


                                      H-3


involving the Guarantor and workout, restructuring or other negotiations or
proceedings of or involving the Guarantor (whether or not the workout,
restructuring or transaction contemplated thereby is consummated) and (ii) the
enforcement of this Section 2.

         3. Guarantee Absolute; Continuing Guarantee. The obligations of each
Guarantor hereunder are joint and several, irrevocable, absolute, independent
and unconditional, and shall not be affected by any circumstance which
constitutes a legal or equitable discharge of a guarantor or surety other than
payment in full of the Guarantied Obligations. In furtherance of the foregoing
and without limiting the generality thereof, the Guarantors agree that: (a) this
Guarantee is a guarantee of payment when due and not of collectibility; (b) the
obligations of each Guarantor hereunder are independent of the obligations of
Supplier under the TPPA and a separate action or actions may be brought and
prosecuted against either Guarantor whether or not any action is brought against
the Supplier and whether or not the Supplier is joined in any such action or
actions; and (c) either Guarantor's payment of a portion, but not all, of the
Guarantied Obligations shall in no way limit, affect, modify or abridge the
Guarantors' liability for any portion of the Guarantied Obligations that has not
been paid. This Guarantee is a continuing guarantee and shall be binding upon
the Guarantors and its successors and assigns.

         4. Actions by Beneficiary. The Beneficiary may from time to time,
without notice or demand and without affecting the validity or enforceability of
this Guarantee or giving rise to any limitation, impairment or discharge of the
Guarantors' liability hereunder, (a) renew, extend, accelerate or otherwise
change the time, place, manner or terms of payment of the Guarantied
Obligations, (b) settle, compromise, release or discharge, or accept or refuse
any offer of performance with respect to, or substitutions for, the Guarantied
Obligations or any agreement relating thereto and/or subordinate the payment of
the same to the payment of any other obligations, (c) request and accept other
guaranties of the Guarantied Obligations and take and hold security for the
payment of this Guarantee or the Guarantied Obligations, (d) release, exchange,
compromise, subordinate or modify, with or without consideration, any security
for payment of the Guarantied Obligations, any other guaranties of the
Guarantied Obligations, or any other obligation of any Person with respect to
the Guarantied Obligations, (e) enforce and apply any security hereafter held by
or for the benefit of the Beneficiary in respect of this Guarantee or the
Guarantied Obligations and direct the order or manner of sale thereof, or
exercise any other right or remedy that the Beneficiary may have against any
such security, and (f) exercise any other rights available to NPC under the
TPPA.

         5. No Discharge. This Guarantee and the obligations of each Guarantor
hereunder shall be valid and enforceable and shall not be subject to any
limitation, impairment or discharge for any reason (other than payment in full
of the Guarantied Obligations), including without limitation the occurrence of
any of the following, whether or not Guarantor shall have had notice or
knowledge of any of them: (a) any failure to assert or enforce or agreement not
to assert or enforce, or the stay or enjoining, by order of court, by operation
of law or otherwise, of the exercise or enforcement of, any claim or demand or
any right, power or remedy with respect to the Guarantied Obligations or any
agreement relating thereto, or with respect to any other guarantee of or
security for the payment of the Guarantied Obligations, (b) any waiver or

                                      H-4


modification of, or any consent to departure from, any of the terms or
provisions of any other guarantee or security for the Guarantied Obligations,
(c) the Guarantied Obligations, or any agreement relating thereto, at any time
being found to be illegal, invalid or unenforceable in any respect, (d) the
application of payments received from any source to the payment of indebtedness
other than the Guarantied Obligations, even if the Beneficiary might have
elected to apply such payment to any part or all of the Guarantied Obligations,
(e) any failure to perfect or continue perfection of a security interest in any
collateral which secures any of the Guarantied Obligations, (f) any defenses,
set-offs or counterclaims which the Supplier may assert against the Beneficiary
in respect of the Guarantied Obligations, including but not limited to failure
of consideration, breach of warranty, payment, statute of frauds, statute of
limitations, accord and satisfaction (other than the right to set off or recoup
overdue undisputed payments due from Beneficiary under the TPPA), and (g) any
other act or thing or omission, or delay to do any other act or thing, which may
or might in any manner or to any extent vary the risk of either Guarantor as an
obligor in respect of the Guarantied Obligations.

         6. Waivers for the Benefit of Beneficiary. Each Guarantor waives, for
the benefit of Beneficiary, until the Guarantied Obligations are paid in full:
(a) any right to require the Beneficiary, as a condition of payment or
performance by the Guarantors, to (i) proceed against the Supplier, any other
guarantor of the Guarantied Obligations or any other Person, (ii) proceed
against or exhaust any security held from the Supplier, any other guarantor of
the Guarantied Obligations or any other Person, or (iii) pursue any other remedy
in the power of the Beneficiary; (b) any defense arising by reason of the
incapacity, lack of authority or any disability or other defense of the Supplier
including, without limitation, any defense based on or arising out of the lack
of validity or the unenforceability of the Guarantied Obligations or any
agreement or instrument relating thereto or by reason of the cessation of the
liability of the Supplier from any cause other than payment in full of the
Guarantied Obligations; (c) 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; (d) (i) any
principles or provisions of law, statutory or otherwise, that are or might be in
conflict with the terms of this Guarantee and any legal or equitable discharge
of Guarantors' obligations hereunder, (ii) the benefit of any statute of
limitations affecting Guarantors' liability hereunder or the enforcement hereof,
(iii) any rights to set-offs, recoupments and counterclaims, and (iv)
promptness, diligence and any requirement that the Beneficiary protect, secure,
perfect or insure any lien on any property subject thereto; (e) notices,
demands, presentments, protests, notices of protest, notices of dishonor and
notices of any action or inaction, including acceptance of this Guarantee; and
(f) to the fullest extent permitted by law, any defenses or benefits that may be
derived from or afforded by law which limit the liability of or exonerate
guarantors or sureties, or which may conflict with the terms of this Guarantee.

         7. Waiver of Rights Against Supplier. Until the Guarantied Obligations
are paid in full, each Guarantor waives any claim, right or remedy, direct or
indirect, that such Guarantor now has or may hereafter have against the Supplier
or any of its assets in connection with this Guarantee or the performance by
such Guarantor of its obligations hereunder, in each case whether such claim,
right or remedy arises in equity, under contract, by statute, under common law
or otherwise and including without limitation (a) any right of subrogation,
reimbursement or

                                      H-5


indemnification that such Guarantor now has or may hereafter have against the
Supplier, (b) any right to enforce, or to participate in, any claim, right or
remedy that the Beneficiary now has or may hereafter have against the Supplier,
and (c) any benefit of, and any right to participate in, any collateral or
security hereafter held by the Beneficiary. Each Guarantor further agrees that,
to the extent the waiver or agreement to withhold the exercise of its rights of
subrogation, reimbursement and indemnification as set forth herein is found by a
court of competent jurisdiction to be void or voidable for any reason, any
rights of subrogation, reimbursement or indemnification such Guarantor may have
against the Supplier or against any collateral or security shall be junior and
subordinate to any rights the Beneficiary may have against Supplier, to all
right, title and interest the Beneficiary may have in any such collateral or
security, and to any right the Beneficiary may have against such other
guarantor.

         8. Representations and Warranties of Guarantor. Each Guarantor
represents and warrants to NPC as follows:

         (a) it is a corporation duly organized, validly existing and in good
standing under the laws of its state of incorporation. Such Guarantor has the
requisite corporate power and authority to own, lease and operate its properties
and to carry on its business as now being conducted.

         (b) it has the corporate power and authority to execute and deliver
this Guarantee and to consummate the transactions contemplated hereby. The
execution and delivery of this Guarantee and the consummation of the
transactions contemplated hereby have been duly and validly authorized by the
Board of Directors of such Guarantor, and no other corporate proceedings on the
part of such Guarantor, including the approval of its shareholders, are
necessary to authorize this Guarantee or to consummate the transactions so
contemplated. This Guarantee has been duly and validly executed and delivered by
such Guarantor and constitutes a valid and binding agreement of such Guarantor,
enforceable against such Guarantor in accordance with its terms.

         (c) There are no legal or arbitral proceedings by or before any
governmental or regulatory authority or agency, now pending or (to such
Guarantor's knowledge) threatened against such Guarantor or its subsidiaries
that could reasonably be expected to have a material adverse effect on the
consolidated financial condition, operations or business taken as a whole of it
and its subsidiaries, except as set forth in periodic filings by such Guarantor
with the Securities and Exchange Commission.

         (d) The representations and warranties made herein will remain true
until such Guarantor has fulfilled its obligations to pay in full the Guaranteed
Obligations.

         9. Set Off. In addition to any other rights the Beneficiary may have
under law or in equity, if any amount shall at any time be due and owing by
either Guarantor to the Beneficiary under this Guarantee, the Beneficiary is
authorized at any time or from time to time, without notice (any such notice
being expressly waived), to set off and to appropriate and to apply any
indebtedness of the Beneficiary owing to such Guarantor and any other property
of such

                                      H-6


Guarantor held by the Beneficiary to or for the credit or the account of such
Guarantor against and on account of the Guarantied Obligations and liabilities
of such Guarantor to the Beneficiary under this Guarantee.

         10. Disputes. Any action, claim or dispute arising out of or relating
to this Guarantee (any such action, claim or dispute, a "Dispute") shall be
submitted in writing to the other Party. In the event the Guarantors and NPC are
unable to resolve the Dispute satisfactorily within thirty (30) days from the
receipt of notice of the Dispute, either the Guarantors or NPC may initiate
arbitration through the serving and filing of a demand for arbitration. The
Guarantors and NPC expressly agree that such arbitration shall be the exclusive
means to further resolve any Dispute and hereby irrevocably waive their right to
a jury trial with respect to any Dispute, provided that at any time a request
made for provisional remedies requesting preservation of respective rights and
obligations under the Guarantee may be resolved by a court of law located in the
County of the principal place of business of NPC. Arbitration shall be conducted
in accordance with Sections 13.4, 13.5, 13.6, 13.7, and 13.8 of the TPPA.

         11. Amendments and Waivers. No amendment, modification, termination or
waiver of any provision of this Guarantee, and no consent to any departure by
either Guarantor therefrom, shall in any event be effective without the written
concurrence of NPC and, in the case of any such amendment or modification,
either Guarantor. Any such waiver or consent shall be effective only in the
specific instance and for the specific purpose for which it was given.

         12. Miscellaneous. It is not necessary for Beneficiary to inquire into
the capacity or powers of either Guarantor or Supplier or the officers,
directors or any agents acting or purporting to act on behalf of any of them.
The rights, powers and remedies given to Beneficiary by this Guarantee are
cumulative and shall be in addition to and independent of all rights, powers and
remedies given to Beneficiary by virtue of any statute or rule of law or in the
TPPA. Any forbearance or failure to exercise, and any delay by Beneficiary in
exercising, any right, power or remedy hereunder shall not impair any such
right, power or remedy or be construed to be a waiver thereof, nor shall it
preclude the further exercise of any such right, power or remedy.

         In case any provision in or obligation under this Guarantee shall be
invalid, illegal or unenforceable in any jurisdiction, the validity, legality
and enforceability of the remaining provisions or obligations, or of such
provision or obligation in any other jurisdiction, shall not in any way be
affected or impaired thereby.

         This Guarantee shall inure to the benefit of Beneficiary and its
respective successors and assigns.

         13. Notices. All notices, requests, demands, waivers, consents and
other communications hereunder shall be in writing, shall be delivered either in
person, by telegraphic, facsimile or other electronic means, by overnight air
courier or by mail, and shall be deemed to have been duly given and to have
become effective (a) upon receipt if delivered in person or by telegraphic,
facsimile or other electronic means, (b) one (1) business day after having been

                                      H-7
