Energy under contract to Buyer; and

                              the applicable transmission scheduling procedures.

          4.1.2     Buyer's Obligation to Take. If Buyer is unable or unwilling
                    --------------------------
                    to take the Asset Bundle Capacity in any Dispatch Hour, the
                    difference (in MWh) between the Asset Bundle Capacity and
                    Buyer's actual take in such Dispatch Hour shall be treated
                    as if it were a part of the Delivered Amount for such
                    Dispatch Hour. Buyer shall give notice to Supplier as soon
                    as reasonably practicable if it is unable or unwilling to
                    take delivery of the full Asset Bundle Capacity in any
                    Dispatch Hour.

          4.1.3     Supplier Rights to Output. Supplier may sell to others any
                    -------------------------
                    portion of the Asset Bundle Capacity which Buyer is
                    unwilling or unable to take.

          4.1.4     Point(s) of Delivery. Supplier shall deliver, and Buyer
                    --------------------
                    shall take delivery of, the Delivered Amount at the Point(s)
                    of Delivery. Subject to Section 4.1.5.2, Supplier shall be
                    responsible for all costs associated with delivery of the
                    Delivered Amount to the Point(s) of Delivery.

          4.1.5     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 approval, such
                    approval not to be unreasonably withheld or delayed.

                    4.1.5.1   If Supplier has designated an alternative Point of
                              Delivery, Supplier shall be responsible for all

                    ----
                    procurement or fuel transportation associated with the Asset
                    Bundle during the term of this Agreement.

          4.1.7     Resale.  Buyer shall not resell the Delivered Amount except
                    ------
                    as necessary to satisfy Buyer's TRR or to maintain
                    reliability.

          4.1.8     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 one Business Day to a subsequent Business Day.
                    Notice to request a review of other than the

                                       8


                    previous month's records, shall be provided with a minimum
                    of seven (7) calendar days written notice by the requesting
                    Party, which 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.

          4.1.9     Transmission Outages.  Supplier shall not be obligated to
                    --------------------
                    deliver the Asset Bundle Capacity, and no liquidated damages
                    shall become due, if the Transmission System outages render
                    the Transmission System incapable of receiving the Asset
                    Bundle Capacity at the specified Point(s) of Delivery,
                    provided that in such event Supplier must deliver Energy up
                    to the capability of the Transmission System to receive such
                    Energy.

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

          4.2.1     The liquidated damages payment provisions are an integral
                    part of this Agreement and form a portion of the
                    consideration for the execution and for any breach of this
                    Agreement.

          4.2.2     If the Delivered Amount is less than the Asset Bundle
                    Capacity 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. An example of the methodology used
                    to calculate Replacement Costs is provided in Exhibit D.
                    Supplier's obligation to make payments under this section is
                    conditioned on Buyer's fulfillment of its obligation to take
                    reasonable steps to mitigate its Replacement Costs
                    consistent with Good Utility Practice.

          4.2.3     The Parties recognize and agree that the payment of such
                    amounts by Supplier 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.

                    (d)  the cause of the Derating;
                    (e)  the extent, if any, to which the Derating is
                         attributable to a Permitted Derating; and

               Notice. Such changes shall be effective for the hours designated
               in such verbal notice, beginning upon issuance of the notice.

     5.1.4     If and to the extent a Derating is the result of one or more of
               the following causes, it shall be a Permitted Derating:

               (a)  approved planned outages pursuant to Section 22;
               (b)  Transmission System outages as described in Section 4.1.9;

               (e)  compliance with constraints on flue gas emissions applicable
                    to the Asset Bundle, provided, however, that to the extent
                    such constraints can be avoided or mitigated through
                    purchasing emission allowances on commercially reasonable
                    terms or other commercially reasonable economic measures
                    short of installing new equipment or retrofitting existing
                    equipment, these constraints shall not be Permitted
                    Deratings; and
               (f)  equipment limitations due to ambient conditions which differ
                    from ISO conditions.

     5.1.5     In respect of any hour, the Asset Bundle Capacity of each unit
               shall be the Asset Bundle Capacity figure stated in Exhibit A
               minus any Permitted Derating applicable during such hour.

                                       10


               5.1.6     For the avoidance of doubt, the Asset Bundle Capacity
                         shall not be affected by Deratings which are not
                         Permitted Deratings.

               5.1.7     In determining whether to declare a Permitted Derating
                         that does not involve a planned outage, Supplier shall
                         take account of operational considerations regarding
                         the items listed in Section 5.1.4 and shall not vary
                         its considerations to reflect different market
                         conditions.

          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; and

          7.2.4     For each Dispatch Hour of the billing period, the shortfall,
                    if any, between the Asset Bundle Capacity and the Delivered
                    Amount.

     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. Examples of this monthly invoice calculation (and
          annual true-up process) are contained in Exhibit C.

     7.4  Buyer's Invoice. In the event any shortfall occurs pursuant to Section
          ---------------
          7.2.4, Buyer shall within 10 days of receipt of Supplier's invoice
          deliver to Supplier a Buyer's invoice detailing any Replacement Costs
          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.

     7.5  Annual True-Up Mechanism.
          ------------------------

          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, Buyer shall pay to
                         Supplier the greater of (A) zero; and (B) the
                         difference in the dollar amount between (x) the Price
                         Ceiling of Energy multiplied by the hourly Delivered
                         Amount of Energy summed over the Contract Year and (y)
                         the amounts invoiced by Supplier for Energy pursuant to
                         Section 7.3 summed over the Contract Year; or

                    (b)  If (i) the Price Ceiling of Energy multiplied by the
                         hourly Delivered Amount of Energy summed over the
                         Contract Year is

                                       12


                         greater than (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, Buyer shall pay to Supplier the greater
                         of (A) zero; and (B) the difference in the dollar
                         amount between (x) the market price of Energy for each
                         hour multiplied by the hourly Delivered Amount of
                         Energy summed over the Contract Year and (y) the
                         amounts invoiced by Supplier for Energy pursuant to
                         Section 7.3 summed over the Contract Year.

          7.5.2     Supplier shall also perform the calculations set forth in
                    Section 7.5.1 using the hourly Asset Bundle Capacity in
                    place of the hourly Delivered Amount of Energy. Supplier
                    shall include in the true-up invoice an amount equal to the
                    lesser of (a) the difference between the amount calculated
                    pursuant to the first sentence of this Section 7.5.2. and
                    the amount calculated pursuant to Section 7.5.1.and (b) the
                    sum of all Replacement Costs incurred during the Contract
                    Year.

          7.5.3     True-up adjustments will be calculated by Supplier within
                    twenty days after each Contract Year. Examples of the true-
                    up calculations and invoice form are set forth in Exhibit E.
                    Interest shall be calculated pursuant to 18 CFR Section
                    35.19a and shall be included in the true-up invoice.
                    Invoices for true-up adjustments shall be submitted by
                    Supplier within thirty (30) days after the end of the
                    Contract Year. Payments for such invoices shall be due from
                    Buyer twenty (20) days from receipt of the true-up invoice.

          Section 14.  Pending resolution of the invoice dispute, payment shall
          be made or offsets or credits taken, as applicable, based upon the
          undisputed portion of the invoice.

          determined to be payable along with interest (calculated pursuant to
          18 CFR Section 35.19a) through the date of payment.  No invoice (or
          payment covered thereby) shall be subject to adjustment unless notice
          or request for adjustment is given within one (1) year of the date
          payment thereunder was due.

     7.8  Method of Payment.  Subject to Sections 7.6 and 7.7, Buyer shall remit
          ------------------
          all amounts due by wire or electronic fund transfer, pursuant to
          Supplier's invoice instructions, no later than twenty days after
          receipt of the invoice.

     7.9  Overdue Payments.  Overdue payments shall bear interest from and

10.  INDEMNIFICATION

     10.1 Supplier shall indemnify Buyer for failure to maintain insurance
          requirements pursuant to Section 12.

     10.2 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.

          10.2.1    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

                                       14


                    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.

          10.2.2    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 Section 10.2.1
                    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.

          10.2.3    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.

          10.2.4.   Such indemnity obligations 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
                    of the statute of limitations period applicable to any third
                    party claim.

     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;

                                       15


                    (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
                           Indemnified 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

     11.1 To the fullest extent permitted by law and notwithstanding other
          provisions of this Agreement, in no event shall a Party, or any of
          their respective successors or assigns be liable to the other Party,
          whether in contract, warranty, tort, negligence, strict liability, or
          otherwise, for special, indirect, incidental, multiple, consequential
          (excluding replacement power costs and other costs pursuant to Section
          4.2, but including lost profits and 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.  However, this
          Limitation of Liability shall not apply with respect to claims
          pursuant to Section 10, or for personal injury, death or property
          damage asserted by third parties as to which a Party is liable
          pursuant to the indemnification provisions hereof or otherwise
          hereunder.

     11.2 The provisions of this Section 11 shall survive any termination,
          cancellation, or suspension of this Agreement.

12.  INSURANCE

     12.1 Supplier shall maintain at its cost and expense, fire, liability,
          business interruption, worker's compensation and other forms of
          insurance relating to the damage, destruction and loss of Supplier's
          Asset Bundle and facilities.  Buyer agrees that it is acceptable for
          Supplier to self-insure in whole or in part against such risks.

     12.2 If the Asset Bundle is damaged or destroyed in whole or in part by a
          casualty, whether insured or not, this Agreement shall continue in
          full force and effect and Supplier shall take all commercially
          reasonable steps to repair and restore the Asset Bundle and
          facilities.

     12.3 Every third-party contract of insurance shall be with an insurer
          qualified to do business in the State of Nevada and with the
          equivalent of a "Best Rating" of "A" or better and shall include
          provisions or endorsements

          (i)   stating that such insurance is primary insurance with respect to
                the interest of Buyer and that any insurance maintained by Buyer
                is excess and not contributory insurance required hereunder;

          (ii)  providing that no reduction, cancellation or expiration of the
                policy shall be effective until ninety (90) days from the date
                written notice thereof is actually received by Buyer. Upon
                Supplier's receipt of any notice of reduction, cancellation or
                expiration, Supplier shall immediately provide written notice
                thereof to Buyer; and

          (iii) naming Buyer as an additional insured on the general liability
                insurance policies as its interests may appear with respect to
                this Agreement.

     12.4 On or before the Effective Date, Supplier shall provide to Buyer, and
          shall continue to provide to Buyer at least fifteen (15) days prior to
          the end of each Contract Year, upon any change in coverage, or at the
          request of Buyer not to exceed once each year, properly executed and

          policies required to be maintained by Suppler under this Agreement.
          Certificates of insurance shall provide the following information:

          (i)   the name of insurance company, policy number and expiration
                date;

                amount of deductibles or self-insured retentions;

          (iii) A statement indicating that Buyer shall receive at least thirty
                (30) days prior written notice of cancellation or expiration of
                a policy, or reduction of liability limits with respect to a
                policy; and

          (iv)  A statement indicating that Buyer has been named as an
                additional insured.

          At Buyer's request, not to exceed once each Contract Year, in addition
          to the foregoing certifications, Supplier shall deliver to Buyer a
          copy of each insurance policy, certified as a true copy by an
          authorized representative of the issuing insurance company.

     12.5 Buyer shall have the right to inspect the original policies of
          insurance applicable to this Agreement at Supplier's place of business
          during regular business hours.

13.  FORCE MAJEURE

     13.1 Each Party shall have the obligation to operate in accordance with
          Good Utility Practice at all times.

     13.2 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 without
          limitation:

                                       17


          (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 (excluding
                 such caused by normal wear and tear or manufacturing defects),
                 and including unscheduled transmission and distribution
                 outages,

          (iii)  sabotage of facilities and equipment,

          (iv)   civil disturbance,

          (v)    labor dispute,

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

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

     13.3 Economic hardship of either Party shall not constitute Force Majeure
          under this Agreement. Nor shall anything contained in this Section or
          elsewhere in this Agreement excuse a Party from strict compliance with
          the obligation of the Parties to comply with the terms of this
          Agreement relating to timely payments.

     13.4 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.

     13.5 Notwithstanding the above provisions, a Force Majeure event shall
          excuse Supplier from its obligation to deliver the Asset Bundle
          Capacity  pursuant to Section 4 of this Agreement only for the first
          seven (7) days of the Force Majeure event.  After such seven day
          period, Supplier must either deliver the Asset Bundle

                                       18


          Capacity at the Point(s) of Delivery or pay liquidated damages
          pursuant to Section 4.2 of this Agreement.

14.  DISPUTES

     14.1 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 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.

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

     14.3 The Parties shall first attempt in good faith to resolve any Dispute.
          In the event that representatives of the Parties are unable to
          satisfactorily resolve the Dispute within 30 (thirty) days from the
          receipt of notice of the Dispute, either Party may by written notice
          to the other refer the Dispute to their respective senior management
          or may demand in writing the submission of the Dispute to binding
          arbitration.  In the event a Party refers a Dispute to its senior
          management, that Party does not waive its right subsequently to demand
          the submission of the Dispute to binding arbitration.  Once a Party
          demands in writing that a Dispute be submitted to binding arbitration,
          the Parties expressly select arbitration as the means to resolve
          Disputes and thereby irrevocably waives their right to a jury trial
          with respect to any Dispute, subject to the following:

          14.3.1    The request 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
                    County of the principal office of Buyer.

     14.4 Subject to the restrictions of Section 6.3, 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 claim over which said agency has jurisdiction.  In such
          case, the other Party may request FERC or the PUCN, as applicable, to
          reject or to waive jurisdiction.  If jurisdiction is rejected or
          waived with respect to all or a portion of the claim, the portion of
          the claim not so accepted by FERC or the PUCN, as applicable, shall be
          resolved through arbitration, as provided in this Agreement.  To the
          extent that FERC or the PUCN, as applicable, asserts or accepts
          jurisdiction over the claim, the decision, finding of fact or order of
          FERC or the PUCN, as applicable, 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, and any
          arbitration proceedings that may have commenced with respect to the
          claim prior to the assertion or acceptance of jurisdiction by FERC or
          the PUCN, as applicable, shall be terminated.

                                       19


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

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

          14.5.2    Arbitrations shall be conducted in accordance with the
                    "Commercial Arbitration Rules" of the American Arbitration
                    Association ("AAA") then in effect.

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

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

                    14.5.3.2  The Parties also agree that each will 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 American Arbitration Association.

                    14.5.3.3  The arbitrator shall not have any current or past
                              substantial business or financial relationships
                              with any party to the arbitration (or their
                              affiliates) and shall not be a vendor, supplier,
                              customer, employee, consultant, or competitor to
                              any of the Parties including their affiliates.

                    14.5.3.4  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 have no power to
                              modify or change any of the above in any manner.
                              The arbitrator shall have no authority to award
                              punitive or multiple damages or any damages
                              inconsistent with this Agreement. The arbitrator
                              shall within 30 days of the conclusion of the
                              hearing, unless such time is extended by agreement
                              of all 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. The
                              decision of the arbitrator rendered in such a
                              proceeding shall be final and binding on the
                              Parties. Judgment on the award may be entered upon
                              it in any court having jurisdiction.

     14.6 The Parties shall proceed with the arbitration expeditiously and the
          arbitration shall, if possible be concluded, in order that the
          decision may be rendered within six (6) months after the filing of the
          demand for arbitration.

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

     14.8   The award 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.

            expenses, including but not limited to legal fees, except that all
            expenses associated with the arbitration shall be apportioned in the
            award of the arbitrator based upon the respective merit of the
            claims of the Parties.

     14.10  This Agreement shall be interpreted pursuant to the laws of the
            State of Nevada, as if executed and performed wholly within that
            state, and the Federal Power Act.

15.  NATURE OF OBLIGATIONS

     15.1   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.

     15.2   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.

16.  SUCCESSORS AND ASSIGNS

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

            16.1.1  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.

            16.1.2  Subject to the requirement that Supplier's assignee fulfills
                    the requirements of this Agreement, including without
                    limitation obligations under Section 3, Supplier may assign
                    this Agreement to an affiliate that directly or indirectly
                    owns at least a fifty percent interest in the Asset Bundle.

     16.2   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

                                       21


               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.

     16.3      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.

     16.4      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.

     16.5      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.

     16.6      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.

                         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

               of an Event of Default include, but are not limited to the
               following:

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

               (ii)  Failure to deliver the Asset Bundle Capacity for a period
                     of thirty 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 being in compliance with neither Section 3.1.1 nor
                     Section 3.1.2; and

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

     18.2      An Event of Default shall be excused:

               18.2.1    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 13;
                         and

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

                                       23


     18.3      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.

     18.4      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.

     18.5      Notwithstanding this Section 18, liquidated damages shall be paid
               to Buyer pursuant to Sections 4.2 and 13.

19.  FACILITY ADDITIONS AND MODIFICATIONS

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

               19.1.1    To the extent additions and modifications interfere
                         with the operation of the Asset Bundle in providing
                         Energy to Buyer beyond the limits for planned outages
                         set forth in Section 22, liquidated damages shall be
                         paid to Buyer pursuant to Section 4.2.

               19.1.2    Supplier shall use reasonable efforts to minimize any
                         adverse impact on Buyer during the course of making
                         such additions and modifications.

               19.1.3    Such additions and modifications shall be conducted in
                         accordance with Good Utility Practice, and all
                         applicable Laws, regulations and Reliability Criteria.

     19.2      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 a material adverse effect
               upon Buyer with respect to operations or performance under this
               Agreement.

20.  COORDINATION

     20.1      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.

21.  EMERGENCY CONDITION RESPONSE

     21.1      Buyer and Supplier shall comply with any applicable requirement
               of any Governmental Authority, NERC, WSCC, ISA, RTO, 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

                                       24


               condition. Supplier shall not be obligated to deliver the Asset
               Bundle Capacity, and no liquidated damages shall become due, if
               generation is reduced in the event of an emergency condition.

     21.2      Each Party shall provide prompt verbal notice to the other Party
               of any emergency condition.

     21.3      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.

22.  OUTAGE SCHEDULING

     22.1      Buyer acknowledges that Supplier may not be the operator of the
               Asset Bundle and may not have direct control over the operation
               of the Asset Bundle.

     22.2      Supplier shall request that the Operator coordinate with Buyer
               any inspections, non-forced outages and maintenance of Supplier's
               Asset Bundle so as to minimize the impact on Buyer under this
               Agreement.

     22.3      Planned Outages.
               ---------------

               22.3.1    Within sixty (60) days following the Effective Date,
                         Supplier shall provide Buyer with a proposed schedule
                         of planned outages for the period beginning on the date
                         of such proposal through March 1, 2003 ("Contract
                         Period"). The proposed planned outage schedule will
                         designate days for each unit in which the Asset Bundle
                         Capacity will be reduced to zero for such unit.
                         Supplier shall be entitled to designate up to 100 unit-
                         days during the Contract Period. Unit-days may be
                         applied to either unit without limitation. Only whole
                         days, being the 24-hour period commencing at 06:00:00,
                         may be designated for planned outages.

               22.3.2    If all unit-days in Supplier's proposed planned outage
                         schedule fall within the months of February, March and
                         November, then it shall not require Buyer's approval
                         and shall become the final planned outage schedule. To
                         the extent Supplier's proposed planned outage schedule
                         designates unit-days which fall outside such months,
                         the inclusion of such unit-days in the final planned
                         outage schedule shall be subject to Buyer's approval.

               22.3.3    Supplier shall be entitled to amend the final planned
                         outage schedule with either (a) six months prior
                         written notice to Buyer or (b) Buyer's approval,
                         provided however, that to the extent such amendments
                         contemplate planned outage unit-days outside of the
                         months February, March and November, Buyer's approval
                         shall be required in respect of such unit-days.

               23.3.4    In considering whether to grant approval under this
                         Section 22.3, Buyer shall take account of the
                         restrictions and constraints imposed on Supplier under
                         the Co-Tenancy Agreement and the Operating Agreement
                         (both as

                                       25


                         defined in the Asset Sale Agreement), and Buyer shall
                         not unreasonably withhold or delay its approval.

23.  REPORTS

     23.1      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 a material adverse effect on Buyer. Supplier shall
               use reasonable efforts to keep Buyer apprised of the status of
               any such matters.

24.  COMMUNICATIONS

     24.1      Supplier's Operating Representatives shall be available 24 hours
               per day for communications with the Control Area Operator and/or
               the ISA and Buyer to facilitate the operations contained in this
               Agreement.

     24.2      Supplier shall, at its expense, maintain and, if reasonably
               necessary, install real-time communications equipment at the
               Asset Bundle to maintain communications between personnel on site
               at the Asset Bundle, Buyer and the Control Area Operator at all
               times. Supplier shall provide at its expense:

               (i)  Ringdown voice telephone lines, and

               (ii) Equipment to transmit to and receive telecopies from Buyer
                    and the Control Area Operator.

     24.3      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:

               24.3.1    A description of the "Abnormal Condition" and the
                         actions to be taken to alleviate the "Abnormal
                         Condition".

               24.3.2    The expected duration including the beginning and
                         ending time of the "Abnormal Condition".

               25.3.3    The amount of any adjustment to the current (real time)
                         level of Energy.

     24.4      Cause of the condition.
               ----------------------

               24.4.1    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 to Buyer.

                         (ii) Cause an unplanned reduction in the rate of
                              delivery of Energy to Buyer.

                                       26


                         (iii)  Cause an unplanned isolation of the Asset Bundle
                                from the transmission system.


     24.5      Supplier shall immediately notify Buyer after such "Abnormal
               Condition" has been alleviated.

25.  NOTICES

28.  COUNTERPARTS AND INTERPRETATION

                                       27


     28.1      This Agreement may be executed in any number of counterparts,
               each of which shall be deemed an original.

     28.2      In the event an ambiguity or question of intent or interpretation
               arises, this Agreement shall be construed as if drafted jointly
               by the Parties and no presumption or burden of proof shall arise
               favoring or disfavoring any Party by virtue of authorship of any
               of the provisions of this Agreement.

     28.3      Any reference to any federal, state, local, or foreign statute or
               law shall be deemed also to refer to all rules and regulations
               promulgated thereunder, unless the context requires otherwise.

     28.4      The word "including" in this Agreement shall mean "including

29.  SEVERABILITY

     29.1      If any term, provision or condition of this Agreement is held to
               be invalid, void or unenforceable by a court or Governmental
               Authority of competent jurisdiction and such holding is subject
               to no further appeal or judicial review, then such invalid, void,
               or unenforceable term, provision or condition shall be deemed
               severed from this Agreement and all 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.

     29.2      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.

30.  WAIVERS

     30.1      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.

31.  AMENDMENTS

     31.1      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

                                       28


               is reasonably expected to materially affect Buyer's PLR service
               under this Agreement.

     31.2      The Parties shall meet to discuss the impact of any changes in
               Buyer's OATT, 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.

     31.3      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.

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

32.  TIME IS OF THE ESSENCE

               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.

     33.2      This Agreement is made subject to present or future state or

     33.3      The Parties hereto agree to execute and deliver promptly, at the
               expense of the Party requesting such action, any and all other

               the term of the Agreement be extended beyond March 1, 2003.
