                                        7

4.   DESIGNATION OF TRANSMISSION DEMAND

     Unless otherwise agreed and for delivery of power and energy to Customer's
     production facilities for consumption up to Customer Contract Demand,
     Bonneville shall provide a maximum Total Transmission Demand to Customer
     equal to Customer's Contract Demand minus the minimum annual contract
     demand associated with expected purchases of federal power, as determined
     by the Customer; provided, however, that Customer's requests for service
     meet the requirements of this Agreement. (For purposes of this section 4,
     "expected purchases of federal power" shall include only purchases of
     one-year or more.) Bonneville shall make available to Customer the
     Transmission Demand requested by Customer at the requested POI if
     Bonneville has (or can acquire through construction of new facilities or
     otherwise) Available Transmission Capacity to provide the requested
     service.

5.   TRANSMISSION OF ELECTRIC POWER

     (a)  During each hour of the term hereof, the Customer shall make available
          or arrange to have made available to Bonneville at the Point(s) of
          Integration, the Total Power Wheeled; and Bonneville shall for each
          such hour make an amount of Electric Power equal to the Total Power
          Wheeled available to the Customer at the Point(s) of Delivery, subject
          to the conditions in paragraphs (a)(1) through (a)(3) below.

          (1)  Bonneville may, but shall not be obligated to, integrate amounts
               of Electric Power on any hour which exceed the Total Transmission
               Demand.

          (2)  Bonneville may, but shall not be obligated to, integrate at a
               Point of Integration on any hour, amounts of Electric Power which
               exceed the Transmission Demand at such Point of Integration.

                                        8

          (3)  Bonneville may, but shall not be obligated to, integrate Electric
               Power from Resources other than Resources listed in the
               Customer's Transmission Parameters Exhibit, provided that the
               Points of Integration for such Electric Power have been mutually
               agreed upon; provided however, any such integration of power, to
               the extent that the Total Transmission Demand is not exceeded,
               shall be provided, in accordance with the Integration of
               Resources Transmission Rate Schedule. The Energy Transmission
               Rate Schedule shall not be applicable to integration of power
               from Resources to the extent such integration does not exceed the
               Total Transmission Demand.

     (b)  If, for any hour, the Customer determines that it has Electric Power
          available for nonfirm transmission over the FCRTS, the Customer may
          request nonfirm transmission service from Bonneville. If Bonneville
          has Available Transmission Capacity to provide the requested service,
          then Bonneville will provide transmission service for such excess
          Electric Power as a separately identified part of its schedule
          pursuant to section 7. Charges for such transmission, if in excess of
          Total Transmission Demand, shall be applied in accordance with the
          Energy Transmission rate schedule, or its successor, attached hereto
          as part of Exhibit A. At its discretion, Bonneville may provide such
          nonfirm transmission service notwithstanding section 4.

          (1)  The option to schedule Electric Power as nonfirm transmission
               service shall not be used to avoid having a Total Transmission
               Demand which reasonably reflects Transmission Demand for each
               Resource and the combined peak demand for wheeling which the
               Customer regularly places on Bonneville. Bonneville shall have
               the right to refuse to provide service on a nonfirm basis if it
               determines that the Transmission Demand at a Point of Integration
               should be increased or the Total Transmission Demand should be
               increased.

                                        9

          (2)  Any transaction using the FCRTS which is exempt from wheeling
               charges or loss assessment at the time of actual transmission,
               such as qualifying transactions under the Coordination Agreement
               (Contract No. 14-03- 48221), and which is subsequently converted
               to a sale to an entity other than Bonneville, shall be
               retroactively billed as nonfirm transmission service and shall be
               assessed losses unless such conversion is allowed or provided for
               under another agreement to which Bonneville is a party. Such
               qualifying transactions shall not be subject to paragraph (b)(3)
               below.

          (3)  Except as provided in subsection 5(b) for nonfirm transmission,
               amounts of Electric Power wheeled hereunder which exceed the
               Transmission Demand shall be billed under the ratchet provision
               of section 6, and/or an appropriate Bonneville rate for
               transmission without prior agreement.

     (c)  To compensate Bonneville for losses incurred in providing services
          hereunder, the Customer shall make available to Bonneville at the
          Customer's Points of Delivery, unless otherwise mutually agreed
          between the Parties, on the current hour, the amounts of Electric
          Power determined pursuant to the Transmission Loss Factors Exhibit for
          service performed pursuant to subsections (a) and (b) above; provided,
          however, that if mutually agreed, losses due to wheeling over
          designated facilities shall be purchased from Bonneville and deemed to
          be delivered to Bonneville by the Customer instead of being made
          available with scheduled energy.

     (d)  Bonneville shall, if requested by the Customer and if it is within
          Bonneville's capability to do so without adversely affecting its other
          obligations, make replacement Electric Power available to the Customer
          hereunder, without additional cost to the Customer except as provided
          in this subsection, if Electric Power to be made available to
          Bonneville pursuant to subsection (a) above cannot

                                       10

          be made available solely because of suspension or interruption of, or
          interference with, the operation of the FCRTS. The Customer shall, at
          Bonneville's option:

          (1)  reimburse Bonneville for any cost or loss of revenue incurred in
               making such replacement Electric Power available;

          (2)  replace all or a portion of such replacement Electric Power with
               the Customer's Electric Power at a time agreed upon by the
               Parties prior to delivery; or

          (3)  reimburse and replace pursuant to paragraphs (1) and (2) above in
               amounts determined by Bonneville which in total are equivalent in
               value to the replacement Electric Power delivered to the Utility
               pursuant to this subsection.

               The method to replace or reimburse shall be specified by
               Bonneville at the time of the Customer's request for replacement
               Electric Power.

     (e)  The Customer shall not use rights obtained under this Agreement to
          provide transmission services for another entity.

6.   PAYMENT BY THE CUSTOMER

     As compensation for services provided hereunder, the Customer shall pay
     Bonneville each month during the term hereof, amounts determined as
     provided in this section and in accordance with the Transmission Parameters
     Exhibit and the Transmission Rate Schedules and General Transmission Rate
     Schedule Provisions Exhibit. Any ratchet demand that may occur as
     determined by Bonneville pursuant to the Transmission Rate Schedules and
     General Transmission Rate Schedule Provisions, does not constitute an

                                       11

     increase in any Transmission Demand approved by Bonneville and any
     continued service at such level will depend on the availability of
     facilities as determined by Bonneville. Any changes in Transmission Demands
     must be requested in accordance with section 10.

     (a)  For integration of Electric Power pursuant to subsection 5(a), the
          Customer shall pay Bonneville in accordance with the appropriate rate
          schedules for integration of resources, use-of-facilities, and other
          transmission services.

     (b)  For nonfirm transmission of Electric Power pursuant to subsection
          5(b), the Customer shall pay Bonneville the rate specified in the
          current rate schedule for nonfirm transmission applicable to the
          facilities being used.

     (c)  If granted a Transmission Demand at a POI, Customer may, pursuant to
          the other provisions of this Agreement, reserve such Transmission
          Demand prior to actual use by paying Bonneville a deposit. Such
          deposit will be determined by Bonneville in a manner comparable to
          that applied to its Utility Customers.

7.   POWER SCHEDULING

     The Customer shall submit or arrange to have submitted to Bonneville by
     1000 hours (Pacific Time) of each Workday:

     (a)  for Resources requiring transmission herein to which the Customer has
          generation control:

          (1)  a retroactive report of the Electric Power supplied to Bonneville
               for each hour of the previous day or days; and

          (2)  at Bonneville's request, estimated amounts of Electric Power as
               specified in paragraph (1) above for each hour of the following
               day or days;

                                       12

     (b)  for Resources requiring transmission herein to which the Customer does
          not have generation control:

          (1)  at Bonneville's request, a schedule in advance of Electric Power
               to be supplied to Bonneville for each hour of the following day
               or days; and

          (2)  if the resource is within Bonneville's control area, a
               retroactive report of the Electric Power supplied by each
               Resource as made available to Bonneville for each hour of the
               previous day or days;

     (c)  a retroactive report of the hourly amounts of Electric Power which the
          Customer made available to Bonneville for nonfirm transmission
          pursuant to subsection 5(b); provided, however, that if requested by
          Bonneville, the Customer shall submit estimated amounts of Electric
          Power to be made available for nonfirm transmission and indicate the
          Point of Integration where such Electric Power will be made available.

8.   REACTIVE POWER

     It is the intent of the Parties hereto that the voltage level at the Points
     of Integration and the Points of Delivery be controlled in accordance with
     prudent utility operating practice. The Parties hereto shall jointly plan
     and operate their systems so as not to place an undue burden on the other
     party to supply or absorb reactive power accompanying or resulting from
     deliveries hereunder.

9.   REVISION OF EXHIBITS

     (a)  The rate schedules included in the Transmission Rate Schedules and
          General Transmission Rate Schedule Provisions Exhibit shall be
          replaced by successor rate

                                       13

          schedules in accordance with the provisions of section 7(i) of the
          Pacific Northwest Power Act and Agency rules. The unit rate or rates
          in such successor rate schedules shall be a non-mileage based rate
          which shall only reflect the distances between POI's and POD's if a
          short distance discount factor has been agreed upon by the Parties.

     (b)  Bonneville shall annually review the Transmission Loss Factors Exhibit
          and shall revise such exhibit as appropriate to incorporate values
          which represent then current FCRTS operating conditions or to
          incorporate any value, used in such exhibit to calculate the losses,
          which has changed due to a change in methodology. Any changes to the
          loss methodology or formula, other than numerical values, shall only
          be made after consultation with the Customer. Bonneville shall prepare
          a new Transmission Loss Factors Exhibit incorporating any revision and
          the revised exhibit shall become effective as of the date specified
          therein.

     (c)  If Bonneville determines that the Use-of-Facilities Charges specified
          in the Transmission Parameters Exhibit or any other charges,
          subsequent charges, or factors used in calculating any charges
          specified in this Agreement must be changed pursuant to sections 19 or
          38 of the General Wheeling Provisions Exhibit, it shall prepare a new
          Transmission Parameters Exhibit or other affected exhibit
          incorporating such revised charges and parameters. Such new exhibits
          shall be substituted for the exhibits then in effect and shall become
          effective as of the date specified therein.

10.  ADDITION OR DELETION OF POINTS OF INTEGRATION AND POINTS OF DELIVERY AND
     CHANGES IN TRANSMISSION DEMANDS

     (a)  Subject to section 4, Points of Integration and Points of Delivery may
          be added and Transmission Demands may be increased, subject to
          Bonneville's determination of Available Transmission Capacity, upon
          3-months' prior written notice to Bonneville, but

                                       14

          no more frequently than once in any 12-month period for any individual
          point or Transmission Demand. Such changes shall be effective for the
          remaining term of this Agreement unless otherwise indicated in the
          appropriate exhibits hereto, or changed pursuant to the provisions
          hereof.

     (b)  Points of Integration and Points of Delivery may be deleted and
          Transmission Demands may be reduced subject to the provisions of
          paragraphs (b)(1) through (b)(6) below.

          (1)  Transmission Demands for individual Points of Integration may be
               reduced no more frequently than once in any 12-month period for
               any Point of Integration, subject to the provisions of paragraph
               (b)(4) below and the notice requirements of paragraph (b)(5)
               below and only:

               (A)  to the extent that, pursuant to the provisions of agreements
                    between the Customer and the owner of a Resource designated
                    in the Transmission Parameters Exhibit as being integrated
                    at such Point of Integration, the Resource owner withdraws
                    all or a portion of the Customer's share of the Resource
                    output;

               (B)  to the extent that the Customer assigns all or a portion of
                    its share of the Resource output;

               (C)  to the extent of a permanent partial or total reduction in
                    the Customer's entitlement to a share of the capability of
                    the Resource;

               (D)  to the extent of the destruction, abandonment, or sale of a
                    Resource integrated at such Point of Integration; or

                                       15

               (E)  to the extent of the discontinuation of operation of a
                    Resource under a final order of a public official having
                    authority to issue such order.

          (2)  A Point of Integration may be deleted, upon 3-months' prior
               written notice to Bonneville, subject to paragraph (b)(4) below,
               but only after its Transmission Demand has been reduced to zero
               pursuant to paragraph (b)(1) above.

          (3)  A Point of Delivery may be deleted, subject to mutual agreement
               of the Parties hereto and to paragraph (b)(4) below, upon
               3-months' prior written notice to Bonneville.

          (4)  A reduction of a Transmission Demand or the deletion of a Point
               of Integration or a Point of Delivery shall not decrease the
               Customer's obligation to pay, for the duration of this Agreement,
               the Use-of-Facility Charges specified in the Transmission
               Parameters Exhibit, except to the extent that another customer of
               Bonneville obligates itself to make such payments to Bonneville
               for the remainder of the duration of this Agreement; provided,
               however, that upon mutual agreement, the Parties may negotiate a
               termination charge in lieu of continued periodic payment of
               Use-of-Facility Charges for the duration of this Agreement.

          (5)  The Customer shall provide Bonneville 3 years' written notice of
               any decrease in Transmission Demand, except as follows:

               (A)  the Customer shall provide 3 months' written notice of a
                    decrease in Transmission Demand if there is an equal
                    increase in Transmission Demand by another customer at the
                    same Point of Integration

                                       16

                    resulting from the sale or assignment of the Resource and
                    involving no loss of revenue to Bonneville; or

               (B)  the Customer shall provide written notice as soon as
                    possible if such decrease is due to involuntary loss of a
                    Resource, or discontinuation of operation of a Resource
                    under a final order of a public official having authority to
                    issue such order.

               (C)  When changes are made pursuant to this section, Bonneville
                    shall incorporate such changes in a new Transmission
                    Parameters Exhibit as soon as practicable.

          (6)  Notwithstanding any other provision but subject to paragraph
               10(b)(4), if Customer increases its purchases of federal power
               Customer shall be entitled to reduce its Transmission Demand at
               any POI(s) in an amount equal to such increase effective on the
               date that such increase in federal service occurs; provided, that
               Customer shall not be entitled, without Bonneville's consent, to
               a Total Transmission Demand in excess of the amount allowed by
               section 4.

     (c)  Notwithstanding any other provision, Customer may request a seasonal
          POI and an associated seasonal Transmission Demand at the POI.
          Bonneville will respond to such request under the procedures and
          standards of Exhibit E.

11.  OPTION TO CONVERT SERVICE

     Customer may convert services under this Agreement to other transmission
     services that Bonneville offers pursuant to the same policies which apply
     to Bonneville's Utility Customers; provided that, subject to subsection
     12(b), the provisions of Exhibit E shall continue to apply to any
     alternative transmission services.

                                       17

12.  REQUESTS AND DISPUTES

     (a)  The Customer may request additional transmission services to be
          provided under other agreements as provided in Exhibit E and, subject
          to the conditions and limitations therein, Bonneville's shall provide
          such services.

     (b)  Unless otherwise expressly provided, requests and disputes regarding
          requests for service (including requests for additional or deleted
          PODs or POIs and for increased or decreased Transmission Demand) and
          disputes under this Agreement shall be governed by Exhibit E;
          provided, that if Bonneville's membership in both -------- the Western
          Regional Transmission Association and the Northwest Regional
          Transmission Association terminates, Exhibit E shall only be used for
          disputes regarding IR services under this Agreement and shall
          terminate for all other purposes; provided, that requests for other
          services pending as of the date of Bonneville's termination of
          membership shall continue to be governed by Exhibit E; provided, that
          if Bonneville joins a successor organization to either the --------
          Westwide or Northwest RTA, or any new organization to implement
          Bonneville's obligations under sections 211 and 212 of the 1992
          Natural Energy Policy Act, then Exhibit E (as modified if necessary to
          provide comparable services to those provided under such successor or
          new organization) shall continue to apply to all requests for services
          by Customer under this Agreement.

13.  POWER SALES CONTRACT

     This Agreement does not modify the current Power Sales Contract between
     Bonneville and the Customer.

                                       18

14.  PRIORITY

     Customer shall have the same priority to Available Transmission Capacity
     for service under this Agreement as transmission service to other
     non-federal regional loads. To the extent Bonneville does not have adequate
     Available Transmission Capacity to meet a Customer's request, Customer
     shall have the same priority to Incremental Facilities for service under
     this Agreement as transmission service to other non-federal regional loads.

15.  ASSIGNMENT

     With Bonneville's consent, which shall not be unreasonably withheld,
     Customer may assign this Agreement or services under this Agreement (e.g.,
     PODs, POIs, and the associated Transmission Demands) to third Parties;
     provided, that the Transmission Service provided under this Agreement to
     such third party shall still serve, directly or indirectly, Customer's
     Facilities.

16.  STABILITY RESERVES

     The Customer shall provide Stability Reserves up to the Transmission Demand
     for transmission services provided pursuant to this Agreement as provided
     herein:

     (a)  Definitions:

          (1)  "Event" is a system condition that results in the need for
               Stability Reserves. The beginning of an event shall be identified
               by a transfer trip or other signal from Bonneville to the
               Customer restricting delivery of energy under this Agreement. The
               end of the Event shall be identified by the Bonneville
               dispatcher's notification to Customer that transmission of all
               energy to which Customer is entitled under this Agreement has
               been restored or notice to the Customer that service to the
               Customer's load will continue to

                                       19

               be fully or partially restricted for reasons other than
               Bonneville Stability Reserves rights under this Agreement.
               Notwithstanding the foregoing, the Event will end (subject to
               reinstatement as provided herein) when an undervoltage or
               underfrequency load shedding signal is received by the Customer
               and, if such undervoltage or underfrequency load shedding signal
               is received by Customer prior to Event Minute 3, then the entire
               Event shall be deemed an event of force majeure.

               The Event shall be reinstated and continue as follows:

               (i)  if the Event Duration was 5 Event Minutes or less, then the
                    Event shall be reinstated if Bonneville restricts deliveries
                    to Customer pursuant to its Stability Reserve rights within
                    2 hours or less of the last Event Minute;

               (ii) if the Event Duration was more than 5 Event Minutes but not
                    more than 15 Event Minutes, then the Event shall be
                    reinstated if Bonneville restricts deliveries to Customer
                    pursuant to its Stability Reserve rights within 4 hours or
                    less of the last Event Minute;

              (iii) if the Event Duration was more than 15 Event Minutes but
                    not more than 22 Event Minutes, then the Event shall be
                    reinstated if Bonneville restricts deliveries to Customer
                    pursuant to its Stability Reserve rights within 6 hours or
                    less of the last Event Minute;

               (iv) if the Event Duration was more than 22 Event Minutes, then
                    the Event shall be reinstated if Bonneville restricts
                    deliveries to Customer pursuant to its Stability Reserve
                    rights within 8 hours or less of the last Event Minute.

                                       20

          (2)  "Event Duration" shall be the total cumulative Event Minutes of
               the Event.

          (3)  "Event Minute" shall be the minutes of restriction (or any
               portion thereof) during an Event. If Bonneville restricts less
               than its full entitlement in any Event Minute, then for purposes
               of defining the Event, the Event Minutes and Event Duration,
               Bonneville shall be deemed to have restricted the entire amount
               of energy wheeled under this Agreement.

          (4)  "Material Plant Damage" shall be the inability to resume
               electrolysis in one or more pots without rebuilding or
               substantially repairing such pot(s).

          (5)  "Stability Reserves" are those reserves, provided by the Customer
               under this Agreement, that are necessary to ensure the stability
               of the Federal Columbia River Transmission System against losses
               of transmission facilities pursuant to the schemes in Exhibit F
               or any additional scheme(s) adopted pursuant to section 16(h)
               herein. Stability Reserves provided under this Agreement shall
               not include, without limitation: (1) stability reserves provided
               by the Customer in the Power Sales Contract; or (2) operating
               reserves or forced outage reserves that Bonneville has acquired
               under the Power Sales Contract or under other agreements.

     (b)  Amount of Stability Reserves. When necessary to provide Stability
          Reserves, Bonneville may restrict deliveries of energy wheeled under
          this Agreement to the Customer's aluminum smelter load (which shall
          not include wheel turning loads) pursuant to the schemes listed in
          Exhibit F and to Customer's other loads under any additional or
          extended scheme(s) adopted pursuant to subsection 16(h), for Stability
          Reserves in the following manner:

          (1)  up to 100 percent of Customer's energy subject to restriction
               under this Agreement for a period of up to 30 Event Minutes per
               Event;

                                       21

          (2)  provided, that Bonneville shall have the sole right to determine
               whether to restrict all or part of Customer's energy subject to
               restriction hereunder, when an Event occurs.

          For accounting purposes, Customer's wheeling turning load shall be
          deemed to be served by all of Customer's energy suppliers (whether the
          sale is made directly to Customer at its production facility or
          whether the sale is made at a remote point and the energy is wheeled
          to Customer's production facility), in proportion to the total annual
          amounts of energy purchased from each such supplier; provided, that if
          the wheel turning load is served exclusively by a supplier other than
          Bonneville who contracted specifically to provide such wheel turning
          service, such wheel turning load shall be excluded from the
          allocation.

          Notwithstanding any other provision of this Agreement, Bonneville
          shall use its best efforts to end an Event as soon as possible and
          Customer agrees to cooperate in development of mechanisms that will
          enhance Bonneville's ability to notify Customer of the end of an
          Event.

          Notwithstanding any other provision of this Agreement, including the
          breach and damages provisions, Bonneville shall have no contractual
          right under this Agreement which would cause Customer to incur
          Material Plant Damages: provided, Bonneville shall not be liable for
          equitable relief or damages for such Material Plant Damage occurring
          within 45 Event Minutes or less of an Event pursuant to a Stability
          Reserve scheme listed in Exhibit F or adopted pursuant to subsection
          16(h).

     (c)  Compensation for Stability Reserves.

                                       22

          (1)  For the right to restrict and for any restrictions provided
               pursuant to subsection (b) for the schemes listed in Exhibit F,
               Bonneville shall pay the Customer a "Reservation Fee" and a "Use
               Fee":

               The Reservation Fee shall be $0.20 per kilowatt-year for
               Customer's entire Transmission Demand.

               The Use Fee shall be 50 mills/kWh of restricted energy during
               Event Minutes 1 through 15 (or any portion thereof) of an Event;
               and, 100 mills/kWh of restricted energy during the Event Minutes
               16 through 30 (or any portion thereof) of an Event.

          (2)  If the Customer's load is not connected to a scheme specified in
               Exhibit F or additional or extended scheme adopted pursuant to
               subsection 16(h), Bonneville shall have no obligation to pay for
               Stability Reserves.

          (3)  The charges specified in this subsection shall not have any
               precedential effect for the purpose of determining reasonable
               stability reserve compensation under other agreements or for
               determining reasonable Stability Reserve compensation for
               additional or extended scheme(s) adopted pursuant to subsection
               16(h) herein. Neither Party shall introduce as evidence of
               reasonable compensation this Agreement or anything herein related
               to the compensation for stability reserves in Bonneville's rate
               cases or similar forums or in a proceeding under subsection 16(h)
               herein.

          (4)  Bonneville's payment obligation hereunder shall not include
               payment for restrictions under events of force majeure or under
               rights provided by other agreements. Such restrictions include
               those restrictions associated with force majeure which cause
               undervoltage and underfrequency load

                                       23

               shedding, future similar schemes of last resort, and outages of
               transmission facilities required for service hereunder.

     (d)  Liquidated Damage. The Parties acknowledge that restrictions beyond
          that allowed by this Agreement may result in damage to and lost
          production by Customer's aluminum reduction facilities prior to
          Material Plant Damage which is difficult to quantify. If the Event
          Duration exceeds 30 Event Minutes, then Bonneville shall be liable to
          Customer as follows:

          (i)  200 mills/kWh of restricted energy during Event Minutes 31
               through 45 (or portion thereof) of an Event;

          (ii) 400 mills/kWh of restricted energy during Event Minutes (or
               portion thereof), after Event Minute 45 of an Event;

         (iii) provided, that in lieu of (ii) and at Customer's option, if the
               Event Duration -------- exceeds 45 Event Minutes, and Customer
               incurs, in its determination, Material Plant Damage as a direct
               result of the restriction, then as to the portion of its
               production facilities that suffers Material Plan Damage,
               Bonneville and Customer agree that these damages can be
               reasonably quantified and, therefore, for that portion of its
               production facilities, Customer may recover actual damages
               (excluding only lost production and lost profits) pursuant to
               subsection 16(e) herein; but such actual damages shall not exceed
               $30 per kW of plant production facilities suffering Material
               Plant Damage. The liquidated damages charges in (i) and (ii),
               above, shall continue to apply to that portion of Customer's load
               which does not suffer Material Plant Damage. For purposes of this
               calculation, the Material Plant Damage shall be deemed to occur
               at the beginning of Event Minute 46.

                                       24

     (e)  Arbitration. Notwithstanding any other provision of this Agreement,
          Bonneville agrees to arbitrate any issue arising under this section 16
          to the full extent allowed under then-existing law, utilizing the
          procedures and standards in Exhibit E applicable to non-rate issues.
          The Arbitrator shall apply federal common law to determine the amount
          of such damages and, if Bonneville alleges any intervening events, to
          rule on such allegation and, if necessary, to determine Bonneville's
          relative share of such damages.

     (f)  Storage. During a period of restriction under subsection 16(b), during
          any further restriction of deliveries in breach of this Agreement, and
          during the period of Customer's inability to take delivery due to such
          breach, all of Customer's energy scheduled and delivered to Bonneville
          under this Agreement shall be deemed stored, at no charge, and shall
          not be spilled. Subject to transmission availability, Bonneville shall
          deliver such energy on demand to Customer's facilities or to another
          entity for resale at no charge other than the transmission charge
          provided herein. The Customer shall take from storage all such energy
          prior to purchasing any additional energy required to recover from the
          Event. If the Customer does not take the energy from storage within 48
          hours of the end of the Event, Bonneville s obligation to return such
          energy shall terminate.

     (g)  Confidentiality. The Parties agree that all material related to plant
          technology, plant operations or to proving damages which is submitted
          by the Customer to Bonneville, the arbitrator or any other party in
          any proceeding under section 16 of this Agreement is confidential. The
          Parties shall jointly request a protective order from the arbitrator:
          (i) preserving the confidentiality of such material; (ii) limiting its
          use to such proceeding; and (iii) requiring its return to Customer at
          the conclusion of the proceeding. Bonneville agrees not to voluntarily
          disclose any such information outside of the agency and agrees to
          restrict access to and use of such information to employees necessary
          to and for purposes associated only with the conduct of such
          proceeding.

                                       25

     (h)  Additional Stability Reserve Schemes. To the extent Bonneville
          determines: (a) the need for additional Stability Reserve scheme(s)
          not listed in Exhibit F that would restrict, at a frequency and
          duration similar to the scheme listed in Exhibit F, the energy subject
          to restriction under this Agreement, (b) the need to apply Stability
          Reserve schemes listed in Exhibit F and additional Stability Reserve
          scheme(s) to energy wheeled under this Agreement to non-aluminum DSIs,
          or (c) the need for modifications to the elements of schemes listed in
          Exhibit F that would significantly change the expected frequency or
          duration of restrictions, then:

          (1)  Bonneville shall consult with Customer on the need for,
               operational characteristics as they affect Customer of, and
               compensation for such scheme(s), and;

          (2)  Bonneville shall consider alternative methods and costs,
               including purchases from non-DSIs, for obtaining such additional
               reserves.

          Customer agrees to cooperate in the development of such scheme(s) and
          shall not unreasonably withhold its consent to implementation of such
          scheme(s).

     (i)  Make-Up Transmission. When an Event ends, Bonneville shall permit,
          subject to Available Transmission Capacity, without additional demand
          or unauthorized, increase charges, short-term, non-recurring demand
          overruns of the Customer s Transmission Demand.

     (j)  Annual Adjustments after October 1, 1995. Subsequent to October 1,
          1995, on the effective date of any IP Premium or successor rate
          adjustment thereafter, the fees and charges (SRCx) identified in 16(c)
          and 16(d) shall be adjusted as follows:

                                       26

                        SRCx     =     SRC base * IP-New
                                                  ------
                                                  IP-93

             where      SRCx     =     Each of the stability reserve fees
                                       identified in 16(c) and charges
                                       identified in 16(d), as adjusted
                                       hereunder, to be effective on the
                                       effective date of any IP or successor
                                       rate adjustment on or after October 1,
                                       1995.

                        SRC Base =     The stability reserve fees as specified
                                       in 16(c) and the changes as specified in
                                       16(d).

                        IP-New   =     Each newly adjusted average IP Premium
                                       rate or successor rate effective after
                                       October 1, 1995, in mills per kWh.  Such
                                       IP Premium or successor rate shall be
                                       calculated at a load factor of 90
                                       percent, and assuming a uniform demand in
                                       all months.  If there is more than one IP
                                       Premium or successor rate, the average
                                       shall be determined by a weighting based
                                       on forecasted sales in the relevant rate
                                       case.

                        IP-93    =     The average IP Premium rate in effect on
                                       October 1, 1993, in mills per kWh.  Such
                                       average IP Premium rate shall be
                                       calculated at a load factor of 90
                                       percent, and assuming a uniform demand in
                                       all months.  If there is more than one IP
                                       or successor rate, the average shall be
                                       determined by a weighting

                                       27

                                       based on foreacasted sales in the
                                       relevant rate case.

SECTION III. DETERMINATION OF TRANSMISSION RATE

A.   From time to time, but not more often than once in each Contract Year, BPA
     shall determine the following data for the facilities which have been
     constructed or otherwise acquired by BPA and which are used to transmit
     electric power:

     1.   The annual cost of the specified FCRTS facilities, as determined from
          the capital cost of such facilities and annual cost ratios developed
          from the Federal Columbia River Power System financial statement,
          including interest and amortization, operation and maintenance,
          administrative and general, and general plant costs.

     2.   The yearly noncoincident peak demands of all users of such facilities
          or other reasonable measurement of the facilities' peak use.

B.   The monthly charge per kilowatt of billing demand shall be one-twelfth of
     the sum of the annual cost of the FCRTS facilities used divided by the sum
     of Transmission Demands. The annual cost per kilowatt of Transmission
     Demand for a facility constructed or otherwise acquired by BPA shall be
     determined in accordance with the following formula:

     A
     -
     D

     Where:

     A = The annual cost of such facility as determined in accordance with A.1.
     above.

     D = The sum of the yearly noncoincident demands on the facility as
     determined in accordance with A.2. above.

The annual cost per kilowatt of facilities listed in the Agreement which are
owned by another entity, and used by BPA for making deliveries to the
transferee, shall be determined from the costs specified in tile Agreement
between BPA and such other entity.

SECTION IV. DETERMINATION OF BILLING DEMAND

Unless otherwise stated in the Agreement, the factor to be used in determining
the kilowatts of billing demand shall be the largest of:

A.   The Transmission Demand in kilowatts specified in the Agreement;

B.   The highest hourly Measured or Scheduled Demand for the month, the Measured
     Demand being adjusted for power factor, or

C.   The Ratchet Demand.

                                       11

                                 Schedule TGT-1
                         Townsend-Garrison Transmission

SECTION I. AVAILABILITY

This schedule shall apply to all agreements which provide for the firm
transmission of electric power and energy over transmission facilities of BPA's
section of the Montana [Eastern] Intertie. Service under this schedule is
subject to BPA's General Transmission Rate Schedule Provisions.

SECTION II. RATE

The monthly charge shall be one-twelfth of the sum of the annual charges listed
below, as applicable and as specified in the agreements for firm transmission.
The Townsend-Garrison 500-kV lines and associated terminal, line compensation.
and communication facilities are a separately identified portion of the Federal
Transmission System. Annual revenues plus credit for government use should equal
annual costs of the facilities, but in any given year there may be either a
surplus or a deficit. Such surpluses or deficits for any year shall be accounted
for in the computation of annual costs for succeeding years. Revenue
requirements for firm transmission use will be decreased by any revenues
received from nonfirm use and credits for all government use. The general
methodology for determining the firm rate is to divide the revenue requirement
by the total firm capacity requirements. Therefore, the higher the total
capacity requirements, the lower will be the unit rate.

If the government provides firm transmission service in its section of the
Montana [Eastern] Intertie in exchange for firm transmission service in a
customer's section of the Montana Intertie, the payment by the government for
such transmission services provided by such customer will be made in the form of
a credit in the calculation of the Intertie Charge for such customer. During an
estimated 1- to 3-year period following the commercial operation of the third
generating unit at the Colstrip Thermal Generating Plant at Colstrip, Montana,
the capability of the Federal Transmission System west of Garrison Substation
may be different from the long-term situation. It may not be possible to
complete the extension of the 500-kV portion of the Federal Transmission System
to Garrison by such commercial operation date. In such event, the 500/230 kV
transformer will be an essential extension of the Townsend-Garrison Intertie
facilities, and the annual costs of such transformer will be included in the
calculation of the Intertie Charge.

However, starting 1 month after extension to Garrison of the 500-kV portion of
the Federal Transmission System, the annual costs of such transformer will no
longer be included in the calculation of the Intertie Charge.

A.   Nonfirm Transmission Charge:

     This charge will be filed as a separate rate schedule and revenues received
     thereunder will reduce the amount of revenue to be collected under the
     Intertie Charge below.

B.   Intertie Charge for Firm Transmission Service:

     Intertie Charge =

     [((TAC/12)-NFR) x (CR-EC)
                       -------]
                         TCR

SECTION III. DEFINITIONS

A.   TAC = Total Annual Costs of facilities associated with the
     Townsend-Garrison 500-kV Transmission line including terminals, and prior
     to extension of the 500-kV portion of the Federal Transmission System to
     Garrison, the 500/230 kV transformer at Garrison. Such annual costs

                                       12

                                 Schedule TGT-93
                                   (Continued)

     are the total of: (1) interest and amortization of associated Federal
     investment and the appropriate allocation of general plant costs; (2)
     operation and maintenance costs; (3) allowance for BPA's general
     administrative costs which are appropriately allocable to such facilities,
     and (4) payments made pursuant to section 7(m) of Public Law 96-501 with
     respect to these facilities. Total Annual Costs shall be adjusted to
     reflect reductions to unpaid total costs as a result of any amounts
     received, under agreements for firm transmission service over the Montana
     Intertie, by the government on account of any reduction in Transmission
     Demand, termination or partial termination of any such agreement or
     otherwise to compensate BPA for the unamortized investment, annual cost,
     removal, salvage, or other cost related to such facilities.

B.   NFR = Nonfirm Revenues, which are equal to: (1) the product of the Nonfirm
     Transmission Charge described in II(A) above, and the total nonfirm energy
     transmitted over the Townsend- Garrison line segment under such charge for
     such month; plus (2) the product of the Nonfirm Transmission Charge and the
     total nonfirm energy transmitted in either direction by the Government over
     the Townsend- Garrison line segment for such month.

C.   CR = Capacity Requirement of a customer on the Townsend-Garrison 500-kV
     transmission facilities as specified in its firm transmission agreement.

D.   TCR = Total Capacity Requirement on the Townsend-Garrison 500-kV
     transmission facilities as calculated by adding (1) the sum of all Capacity
     Requirements (CR) specified in transmission agreements described in section
     I; and (2) the Government's firm capacity requirement. The Government's
     firm capacity requirement shall be no less than the total of the amounts,
     if any, specified in firm transmission agreements for use of the Montana
     Intertie.

E.   EC = Exchange Credit for each customer which is the product of: (1) the
     ratio of investment in the Townsend-Broadview 500-kV transmission line to
     the investment in the Townsend-Garrison 500-kV transmission line; and (2)
     the capacity which the Government obtains in the Townsend- Broadview 500-kV
     transmission line through exchange with such customer. If no exchange is in
     effect with a customer, the value of EC for such customer shall be zero.

                                 Schedule AC-93
                          Southern Intertie Annual Cost

SECTION I. AVAILABILITY

This schedule is applicable to all parties (New Owners) that execute PNW AC
Intertie Capacity Ownership Agreements (Agreements) and will be effective on the
date described in the Agreement. Service under this schedule is subject to BPA's
General Transmission Rate Schedule Provisions.

SECTION II. RATE

The rate charges reflect the terms of the Memorandum of Understanding (MOU),
signed in the Fall of 1991, between BPA and potential New Owners. The MOU
provides for the payment by New Owners of their prorated share of: (1) BPA's
annual operations, maintenance, and general plant expense (including applicable
overheads) properly chargeable to the AC Intertie facilities; and (2) BPA's
share of capitalized replacements on the AC Intertie. The monthly charge shall
be the sum of the charges specified in sections II.A and II.B.

A.   Operations, Maintenance, and General Plant

     The monthly charge shall equal $325 per megawatt of billing demand.

B.   Replacements

     The monthly charge shall equal $0 per megawatt of billing demand.

SECTION III. ADJUSTMENT TO REPLACEMENTS RATE

A.   Determination of Billing Adjustment

     New Owners will receive a billing adjustment if BPA incurs AC Intertie
     replacement cost during the rate period. The Replacements Rate Adjustment
     equals:

     AC lntertie work orders ($000) * %
     ----------------------------------
               725 MW * # months

     where:

     "# months" equals: (1) the number of months that this rate schedule is in
     effect during the fiscal year for the Initial Replacements Rate Adjustment;
     or (2) the number of months in the rate period for the Final Replacements
     Rate Adjustment; and

     "%" equals the New Owners' percentage share of BPA's total AC Intertie
     Rated Transfer Capability as specified in the Agreements.

B.   Initial Replacements Rate Adjustment

     New Owners will receive a billing adjustment for each fiscal year that BPA
     incurs AC Intertie replacement cost. At the end of each fiscal year, the
     cost associated with AC Intertie capital replacement work orders that have
     closed during the fiscal year will be determined. The unit rate that would
     result using these closed work orders is the basis of the Initial
     Replacements Rate Adjustment.

     1.   Notice Provisions

          Following each fiscal year, BPA shall notify all New Owners by
          December 15 of the proposed Replacements Rate Adjustment. BPA will
          provide the calculation of the adjustment and a short description of
          the work performed and the associated cost used as the basis for
          billing adjustment. In addition to written notification, BPA may, but
          is not obligated to, hold a public meeting to clarify its
          determinations.

                                       14

                                 Schedule AC-93
                                   (Continued)

          Written comments on the Initial Replacements Rate Adjustment will he
          accepted through the end of January. Consideration of comments
          submitted by the New Owners may result in the billing adjustment
          differing from the initially proposed adjustment. BPA shall notify all
          New Owners of the Initial Replacements Rate Adjustment by the last day
          of February.

     2.   Adjustment of Monthly Bills

          An adjustment will be made on the New Owner's monthly bill prepared
          during March. The Initial Replacements Rate adjustment will be
          multiplied by the sum of the monthly billing factors from the relevant
          fiscal year (i.e., the New Owner's share in megawatts of BPA's PNW AC
          Intertie Rated Transfer Capability multiplied by the number of months
          that this rate schedule is effective during the fiscal year). The
          Initial Replacements Rate Adjustment will appear as a charge to the
          New Owner on the monthly bill prepared during March.

C.   Final Replacements Rate Adjustment

     The actual costs associated with the AC Intertie capital replacement work
     orders that occur during the rate period may change after BPA performs its
     final analysis of the work orders. BPA shall compare the unit rate for the
     rate period using the results of the final work order analysis to the
     weighted average of the unit rates from the Initial Replacements Rate
     Adjustments.

     1.   Notice Provisions

          BPA shall notify all New Owners in May 1998 of the results of the
          calculations, an explanation of work order change(s), and any
          resulting billing adjustment. Written comments from New Owners will be
          accepted through the end of June. BPA shall notify all New Owners of
          the Final Replacements Rate Adjustment by July 31. Consideration of
          comments submitted by the New Owners may result in the Final
          Replacements Rate Adjustment differing from the initially proposed
          adjustment.

     2.   Adjustment of Monthly Bills

          If the absolute value of the Final Replacements Rate Adjustment is
          greater than or equal to $1 per megawatt per month, an adjustment will
          be made on the New Owner's monthly bill prepared during August. For
          each New Owner, the Final Replacements Rate Adjustment will be
          multiplied by the sum of the monthly billing factors from the relevant
          fiscal years (i.e., the New Owner's share in megawatts of BPA's PNW AC
          Intertie Rated Transfer Capability multiplied by the number of months
          that this rate schedule is effective during the fiscal years). The
          Final Replacements Rate Adjustment will appear as a charge or credit
          to the New Owner on the monthly bill prepared during August. Interest,
          as determined by BPA's Office of Financial Management, will be
          included in any adjustment.

SECTION IV. BILLING FACTOR

The billing demand shall be the New Owner's capacity ownership share in
megawatts of BPA's PNW AC Intertie Rated Transfer Capability as specified in the
Agreement.

     rate schedules required by agreement to remain in force.

     Transmission service provided shall be subject to the following Acts, as
     amended: the Bonneville Project Act, the Regional Preference Act (P.L.
     88-552), the Federal Columbia River Transmission System Act, and the
     Pacific Northwest Electric Power Planning and Conservation Act, and the
     Energy Policy Act of 1992, Pub. L. 102-486, 106 Stat. 2776 (1992).

     The meaning of terms used in the transmission rate schedules shall be as
     defined in agreements or provisions which are attached to the Agreement or
     as in any of the above Acts.

C.   Interpretation

     If a provision in the executed Agreement is in conflict with a provision
     contained herein, the former shall prevail.

SECTION II. BILLING FACTOR DEFINITIONS AND BILLING ADJUSTMENTS

A.   Billing Factors

     1.   Scheduled Demand

          The largest of hourly amounts wheeled which are scheduled by the
          customer during the time period specified in the rate schedules.

     2.   Metered Demand

          Metered Demand in kilowatts shall be the largest of the 60-minute
          clock-hour integrated demands measured by meters installed at each POD
          during each time period specified in the applicable rate schedule.
          Such measurements shall be made as specified in the Agreement. BPA, in
          determining the Metered Demand, will exclude any abnormal readings due
          to or resulting from: (a) emergencies or breakdowns on, or maintenance
          of, the FCRTS; or (b) emergencies on the customer's facilities,
          provided that such facilities have been adequately maintained and
          prudently operated as determined by BPA. If more than one class of
          power is delivered to any POD, the portion of the metered quantities
          assigned to any class of power shall be as agreed to by the parties.
          The amount so assigned shall constitute the Metered Demand for such
          class of power.

                                       16

     3.   Transmission Demand

          previous 11 billing months, such decrease will be reflected in
          determining the Ratchet Demand.

B.   Billing Adjustments

     Average Power Factor

     The adjustment for average power factor, when specified in a transmission
     rate schedule or in the Agreement, shall be made in accordance with the
     average power factor section of the General Wheeling Provisions.

     To maintain acceptable operating conditions on the Federal system, BPA may
     restrict deliveries of power at any time that the average leading power
     factor or average lagging power factor for all classes of power delivered
     to such point or to such system is below 85 percent.

SECTION IV. BILLING INFORMATION

A.   Payment of Bills

     Bills for transmission service shall be rendered monthly by BPA. Failure to
     receive a bill shall not release the customer from liability for payment.
     Bills for amounts due of $50,000 or more must be paid by direct wire
     transfer: customers who expect that their average monthly bill will not
     exceed $50,000 and who expect special difficulties in meeting this
     requirement may request, and BPA may approve, an exemption from this
     requirement. Bills for amounts due BPA under $50,000 may be paid by direct
     wire transfer or mailed to the Bonneville Power Administration, P.O. Box
     6040, Portland, Oregon 97228-6040, or to another location as directed by
     BPA. The procedures to be followed in making direct wire transfers will be
     provided by the Office of Financial Management and updated as necessary.

     1.   Computation of Bills

          The transmission billing determinant is the electric power quantified
          by the method specified in the Agreement or Transmission Rate
          Schedule. Scheduled power or metered power will be used.

          The transmission customer shall provide necessary information to BPA
          for any computation required to determine the proper charges for use
          of the FCRTS, and shall cooperate with BPA in the exchange of
          additional information which may be reasonably useful for respective
          operations.

          Demand and energy billings for transmission service under each
          applicable rate schedule shall be rounded to whole dollar amounts, by
          eliminating any amount which is less than 50 cents and increasing any
          amounts from 50 cents through 99 cents to the next higher dollar.

     2.   Estimated Bills

          At its option, BPA may elect to tender an estimated bill to be
          followed at a subsequent billing date by a final bill. The estimated
          bill shall have the validity of and be subject to the same payment
          provisions as a final bill.

     3.   Billing Month

          For charges based on scheduled quantities, the billing month is the
          calendar month. For charges based on metered quantities, the billing
          month is defined as the interval between scheduled meter-reading
          dates. The billing month will not exceed 31 days in any case. While it
          may be necessary to read meters on a day other than the scheduled
          meter-reading date, for determination of billing demand, the billing
          month will cease at 2400 hours on the last scheduled meter- reading
          date. Schedules will be predetermined. The customer must give 30 days
          notice to request a change to the schedule.

                                       19

     4.   Due Date

          Bills shall be due by close of business on the 20th day after the date
          of the bill (due date). Should the 20th day be a Saturday, Sunday, or
          holiday (as celebrated by the customer), the due date shall be the
          next following business day.

     5.   Late Payment

          Bills not paid in full on or before close of business on the due date
          shall be subject to a penalty charge of $25. In addition, an interest
          charge of one-twentieth percent (0.05 percent) shall be applied each
          day to the sum of the unpaid amount and the penalty charge. This
          interest charge shall be assessed on a daily basis until such time as
          the unpaid amount and penalty charge are paid in full.

          Remittances received by mail will be accepted without assessment of
          the charges referred to in the preceding paragraph provided the
          postmark indicates the payment was mailed on or before the due date.
          Whenever a power bill or a portion thereof remains unpaid subsequent
          to the due date and after giving 30 days' advance notice in writing,
          BPA may cancel the contract for service to the customer. However, such
          cancellation shall not affect the customer's liability for any charges
          accrued prior thereto under such agreement.

     6.   Disputed Billings

          In the event of a disputed billing, full payment shall be tendered to
          BPA and the disputed amount noted. Disputed amounts are subject to the
          late payment provisions specified above. BPA shall separately account
          for the disputed amount. If it is determined that the customer is
          entitled to the disputed amount, BPA shall refund the disputed amount
          with interest, as determined by BPA's Office of Financial Management.

          BPA retains the right to verify, in a manner satisfactory to the
          Administrator, all data submitted to BPA for use in the calculation of
          BPA's rates and corresponding rate adjustments. BPA also retains the
          right to deny eligibility for any BPA rate or corresponding rate
          adjustment until all submitted data have been accepted by BPA as
          complete, accurate, and appropriate for the rate or adjustment under
          consideration.

     7.   Revised Bills

          As necessary, BPA may render a revised bill.

          a.   If the amount of the revised bill is less than or equal to the
               amount of the original bill, the revised bill shall replace all
               previous bills issued by BPA that pertain to the specified
               customer for the specified billing period and the revised bill
               shall have the same date as the replaced bill.

          b.   If a revision causes an additional amount to be due BPA or the
               specified customer beyond the amount of the original bill, a
               revised bill will be issued for the difference and the date of
               the revised bill shall be its date of issue.

contract body to which they are an exhibit. If a provision in such contract body
is in conflict with a provision contained herein, the former shall prevail.

     (b) If a provision in the General Transmission Rate Schedule Provisions is
in conflict with a provision in this exhibit or the contract body, this exhibit
or the contract body shall prevail.

     (c) Nothing contained in this contract shall, in any manner, be construed
to abridge, limit, or deprive any party thereto of any means of enforcing any
remedy, either at law or in equity, for the breach of any of the provisions
thereof which it would otherwise have.

     2.  Definitions. As used in this contract:

     (a) "Contractor," "Utility" or "Borrower" means the party to this contract
other than Bonneville.

     (b) "Federal System" or "Federal System Facilities" means the facilities of
the Federal Columbia River Power System, which for the purposes of this contract
shall be deemed to include the generating facilities of the Government in the

facilities:

          (1) from which Bonneville receives all or a portion of the generating
     capability (other than station service) for use in meeting Bonneville's
     loads, such facilities being included only to the extent Bonneville has the
     right to receive such capability; provided, however, that "Bonneville's
     loads" shall not include that portion of the loads of any Bonneville
     customer which are served by a nonfederal generating resource purchased or
     owned directly by such customer which may be scheduled by Bonneville;

          (2) which Bonneville may use under contract, or license; or

          (3) to the extent of the rights acquired by Bonneville pursuant to the
     Treaty, between the Government and Canada, relating to the cooperative
     development of water resources of the Columbia River Basin, signed in
     Washington, D.C., on January 17, 1961.

     (c) "Integrated Demand" means the number of kilowatts which is equal to the
number of kilowatt-hours delivered at any point during a clock hour.

     (d) "Measured Demand" means the maximum Integrated Demand for a billing
month determined from measurements made as specified in the contract or as
determined in section 4 hereof when metering or other data are not available

                                        2

for such purpose. Bonneville, in determining the Measured Demand, will exclude
any abnormal Integrated Demands due to, or resulting from (a) emergencies or
breakdowns on, or maintenance of, either parties' facilities, and (b)
emergencies on facilities of the Transferee, provided that such facilities have
been adequately maintained and prudently operated as determined by Bonneville.

     If the contract provides for delivery of more than one class of power to a
Transferee at any Point of Delivery, the portion of each Integrated Demand
assigned to any class of power shall be determined as specified in the contract.
The portion of the Integrated Demand so assigned shall constitute the Measured
Demand for such class of power.

     (e) "Month" means the period commencing at the time when the meters
mentioned in this contract are read by Bonneville and ending approximately 30
days thereafter when a subsequent reading of such meters is made by Bonneville.

     (f) "Point(s) of Delivery" means the point(s) of delivery listed either in
the Points of Delivery Exhibit to this contract or in the body of this contract.

     (g) "System" or "Facilities" means the transmission facilities: (1) which
are owned or controlled by either party, or (2) which either party may use under
lease, easement, or license.

     (h) "Transferee" means an entity which receives power or energy from the
system of the Transferor.

     (i) "Transferor" means an entity which receives at one point on its system
a supplying entity's power or energy and makes such power or energy available at
another point on its system for the account of the delivering entity or a third
party.

     (j) "Uncontrollable Forces" means:

          (1) strikes or work stoppage affecting the operation of the
     Contractor's works, system, or other physical facilities or of the Federal
     System Facilities or the physical facilities of any Transferee upon which
     such operation is completely dependent; the term "strikes or work stoppage"
     shall be deemed to include threats of imminent strikes or work stoppage
     which reasonably require a party or Transferee to restrict or terminate its
     operations to prevent substantial loss or damage to its works, system, or
     other physical facilities; or

          (2) such of the following events as the Contractor or Bonneville or
     any Transferee by exercise of reasonable diligence and foresight, could not
     reasonably have been expected to avoid:

               (A) events, reasonably beyond the control of either party or any
          Transferee, causing failure, damage, or destruction of any works,
          system or facilities of such party or Transferee; the word "failure"

                                        3

          shall be deemed to include interruption of, or interference with, the
          actual operation of such works, system, or facilities;

               (B) floods or other conditions caused by nature which limit or
          prevent the operation of, or which constitute an imminent threat of
          damage to, any such works, system, or facilities; and

               (C) orders and temporary or permanent injunctions which prevent
          operation, in whole or in part, of the works, system, or facilities of
          either party or any Transferee, and which are issued in any bona fide
          proceeding by:

                    i. any duly constituted court of general jurisdiction; or

                    ii. any administrative agency or officer, other than
               Bonneville or its officers, provided by law (a) if said party or
               Transferee has no right to a review of the validity of such order
               by a court of competent jurisdiction; or (b) if such order is
               operative and effective unless suspended, set aside, or annulled
               by a court of competent jusidiction and such order is not
               suspended, set aside, or annulled in a judicial proceeding
               prosecuted by said party or Transferee in good faith; provided,
               however, that if such order is suspended, set aside, or annulled
               in such a judicial proceeding, it shall be deemed to be an
               "uncontrollable force" for the period during which it is in
               effect; provided, further, that said party or Transferee, shall
               not be required to prosecute such a proceeding, in order to have
               the benefits of this section, if the parties agree that there is
               no valid basis for contesting the order.

               The tem "operation" as used in this subsection shall be deemed to
          include construction, if construction is required to implement the
          contract and is specified therein.

     3.  Prior Demands.

     (a) In determining any credit demand mentioned in, or money compensation to
be paid under this contract for any month, Integrated Demands at which electric
energy was delivered by the Transferor at Points of Delivery mentioned herein
for the account of the other party to this contract prior to the date upon which
the contract takes effect shall be considered in the same manner as if this
contract had been in effect.

     (b) If either party has delivered electric power and energy to the other
party at any Point of Delivery specified in this contract or in any previous
contract, and such Point of Delivery is superseded by another Point of Delivery
specified in this contract, the Measured Demands, if any, at the superseded
Point of Delivery shall be considered for the purpose of determining the charges
paid to the Transferor for the electric power and energy delivered under this
contract at such superseded point.

     4.  Measurements. Except as it is otherwise provided in section 7, each
measurement of each meter mentioned in this contract shall be the measurement

                                        4

automatically recorded by such meter or, at the request of either party, the
measurement as mutually determined by the best available information.

     If it is provided in this contract that measurements made by any of the
meters specified therein are to be adjusted for losses, such adjustments shall
be made by using factors, or by compensating the meters, as agreed upon by the
parties hereto. If changes in conditions occur which substantially affect any
such loss factor or compensation, it will be changed in a manner which will
conform to such change in conditions.

     5.  Measurements and Installation of Meters. Bonneville may at any time
install a meter or metering equipment to make the measurements for any Point of
Delivery required for any computation or determination mentioned in this
contract, and if so installed, such measurements shall be used thereafter in
such computation or determination.

     6.  Tests of Metering Installations. Each party to this contract shall, at
its expense, test its metering installations associated with this contract at
least once every two years, and, if requested to do so by the other party, shall
make additional tests or inspections of such installations, the expense of which
shall be paid by such other party unless such additional tests or inspections
show the measurements of such installations to be inaccurate as specified in
section 7. Each party shall give reasonable notice of the time when any such
test or inspection is to be made to the other party who may have representatives
present at such test or inspection. Any component of such installations found to
be defective or inaccurate shall be adjusted, repaired or replaced to provide
accurate metering.

     7.  Adjustment for Inaccurate Metering

     (a) If any meter mentioned in this contract fails to register, or if the
measurement made by such meter during a test made as provided in section 6
varies by more than one percent from the measurement made by the standard meter
used in such test, or if an error in meter reading occurs, adjustment shall be
made correcting all measurements for the actual period during which such
innacurate measurements were made, if such period can be determined. If such
period cannot be determined, the adjustment shall be made for the period
immediately preceding the test of such meter which is equal to the lesser of (a)
one-half the time from the date of the last preceding test of such meter, or (b)
six months. Such corrected measurements shall be used to recompute the amounts
of any electric power and energy to be made available, or any credits to be made
in any exchange energy account, and of any money compensation to be paid to the
Transferor as provided in this contract.

     (b) If the credit theretofore made to the Transferor in the exchange energy
account varies from the credit to be made as recomputed, the amount of the
variance will be credited in such exchange energy account to the party entitled
thereto.

     (c) If the money compensation theretofore paid to the Transferor varies
from the money compensation to be paid as recomputed, the amount of the variance
will be paid to the party entitled thereto after both parties have agreed to
such recomputation and within 30 days after receipt of invoice by the designated
payment office of the payer; provided, however, that the other

                                        5

party may deduct such amount due it from any money compensation which thereafter
becomes due the Transferor under this contract.

     8.  Character of Service. Unless otherwise specifically provided for in the
contract, electric power and energy made available pursuant to this contract
shall be in the form of three-phase current, alternating at a nominal frequency
of 60 hertz.

     9.  Point(s) of Delivery and Delivery Voltage. Electric power and energy
shall be delivered to each Transferee at such point or points and at such
voltage or voltages as are agreed upon by the parties hereto.

     10. Combining Deliveries Coincidentally. If it is provided in this contract
that charges for electric power and energy made available at two or more Points
of Delivery will be made by combining deliveries at such points coincidentally:

     (a) the total Measured Demand to be considered in determining the billing
demand for each billing month shall be the largest sum obtained by adding for
each demand interval of such month the corresponding Integrated Demands of the
Transferee at all such points after adjusting said Integrated Demands as
appropriate to such points;

     (b) the number of kilowathours to be used in determining the energy charge,
if any, and the average power factor at which electric energy is delivered at
such points under this contract, during such month, shall be the sum of the
amounts of electric energy delivered at such points under this contract during
such month; and

     (c) the number of reactive kilovolt-ampere-hours to be used in determining
such average monthly power factor shall be the sum of the reactive
kilovolt-ampere-hours delivered at such points under this contract such month.

     11. Suspension of Deliveries. The other party to this contract may at any
time notify the Transferor in writing to suspend the deliveries of electric
power and energy provided for in this contract. Upon receipt of any such notice,
the Transferor will forthwith discontinue, and will not resume, such deliveries
until notified to do so by the other party, and upon receipt of such notice from
the other party to do so, will forthwith resume such deliveries.

     12. Continuity of Service. Either party may temporarily interrupt or reduce
deliveries of electric power and energy if such party determines that such
interruption or reduction is necessary or desirable in case of system
emergencies, Uncontrollable Forces, or in order to install equipment in, make
repairs to, make replacements within, make investigations and inspections of, or
perform other maintenance work on its system. Except in case of emergency and in
order that each party's operations will not be unreasonably interfered with,
such party shall give notice to the other party of any such interruption or
reduction, the reason therefor, and the probable duration thereof to the extent
such party has knowledge thereof. Each party shall effect the use of temporary
facilities or equipment to minimize the effect of any such interruption or
outage to the extent reasonable or appropriate.

                                        6

     13. Uncontrollable Forces. Each party shall notify the other as soon as
possible of any Uncontrollable Forces which may in any way affect the delivery
of power hereunder. In the event the operations of either party are interrupted
or curtailed due to such Uncontrollable Forces, such party shall exercise due
diligence to reinstate such operations with reasonable dispatch.

     14. Reducing Charges for Interruptions. If deliveries of electric power and
energy to the Transferee are suspended, interrupted, interfered with or
curtailed due to Uncontrollable Forces on either the Transferee's System or
Transferor's System, or if the Transferor interrupts or reduces deliveries to
the Transferee for any of the reasons stated in section 12 hereof, the credit in
the exchange energy account which would otherwise be made, or the money
compensation which would otherwise be paid to the Transferor, shall be
appropriately reduced. No interruption, or equivalent interruption, of less than
30 minutes duration will be considered for computation of such reduction in
charges.

     15. Net Billing. Upon mutual agreement of the parties, payment due one
party may be offset against payments due the other party under all contracts
between the parties hereto for the sale and exchange of electric power and
energy, use of transmission facilities, operation and maintenance of electric
facilities, lease of electric facilities, mutual supply of emergency and standby
electric power and energy, and under such other contracts between such parties
as the parties may agree, unless otherwise provided in existing contracts
between the parties. Under contracts included in this procedure, all payments
due one party in any month shall be offset against payments due the other party
in such month, and the resulting net balance shall be paid to the party in whose
favor such balance exists unless the latter elects to have such balance carried
forward to be added to the payments due it in a succeeding month.

     16. Average Power Factor.

     (a) The formula for determining average power factor is as follows:

Average Power Factor =                     Kilowatthours
                       ---------------------------------------------------------
                       /(Kilowatthours)2 + (Reactive Kilovolt-ampere-hours)2

The data used in the above formula shall be obtained from meters which are
ratcheted to prevent reverse registration.

     (b) When delivery of electric power and energy by the Transferor at any
point is commingled with any other class or classes of power and it is
impracticable to separately meter the kilowatthours and reactive
kilovolt-ampere-hours for each class, the average power factor of the total
delivery of such electric power and energy for the month will be used, where
applicable, as the power factor for each of the separate classes.

     (c) Except as it is otherwise specifically provided in this contract, no
adjustment will be made for power factor at any point of delivery described in
this contract while the varhours delivered at such point are not measured.

                                        7

     (d) The Transferor may, but shall not be obligated to, deliver electric
energy hereunder at a power factor of less than 0.85 leading or lagging.

     17. Permits.

     (a) If any equipment or facilities associated with any Point of Delivery
and belonging to a party to this contract are or are to be located on the
property of the other party, a permit to install, test, maintain, inspect,
replace, repair, and operate during the term of this contract and to remove such
equipment and facilities at the expiration of said term, together with the right
of entry to said property at all reasonable times in such term, is hereby
granted by the other party.

     (b) Each party shall have the right at all reasonable times to enter the
property of the other party for the purpose of reading any and all meters
mentioned in this contract which are installed on such property.

     (c) If either party is required or permitted to install, test, maintain,
inspect, replace, repair, remove, or operate equipment on the property of the
other, the owner of such property shall furnish the other party with accurate
drawings and wiring diagrams of associated equipment and facilities, or, if such
drawings or diagrams are not available, shall furnish accurate information
regarding such equipment or facilities. The owner of such property shall notify
the other party of any subsequent modification which may affect the duties of
the other party in regard to such equipment, and furnish the other party with
accurate revised drawings, if possible.

     18. Ownership of Facilities.

     (a) Except as otherwise expressly provided, ownership of any and all
equipment, and of all salvable facilities installed or previously installed by a
party to this contract on the property of the other party shall be and remain in
the installing party.

     (b) Each party shall identify all movable equipment and all other salvable
facilities which are installed by such party on the property of the other by
permanently affixing thereto suitable markers plainly stating the name of the
owner of the equipment and facilities so identified. Within a reasonable time
subsequent to initial installation, and subsequent to any modification of such
installation, representatives of the parties shall jointly prepare an itemized
list of said movable equipment and facilities.

     19. Adjustment for Change of Conditions. If changes in conditions hereafter
occur which substantially affect any factor required by this contract to be used
in determining (a) any credit in any exchange energy account to be made, money
compensation to be paid, or amount of electric power and energy or losses to be
made available to one party by the other party, or (b) any maximum replacement
demand, or average power factor mentioned in this contract, such factor will be
changed in an equitable manner which will conform to such changes of conditions.
If an increase in the capacity of the facilities being used by the Transferor in
making deliveries hereunder is required at any time after execution of this
contract to enable the Transferor to make the deliveries herein required
together with those required for its own operations, the construction or
installation of additional or other

                                        8

equipment or facilities for that purpose shall be deemed to be a change of
conditions within the meaning of the preceding sentence.

     If, pursuant to the terms of the agreement establishing such exchange
energy account, another rate is substituted for the rate to be used in settling
the balance in such account, the number of kilowatthours to be credited to the
Transferor in such account for each month as provided in this agreement, shall
be changed for each month thereafter to the amount computed by multiplying such
number of kilowatthours by 2.5 mills and dividing the resulting product by the
currently effective substituted rate in mills per kilowatthour.

     20. Dispute Resolution and Arbitration.

     (a) Pending resolution of a disputed matter the parties will continue
performance of their respective obligations pursuant to this contract. If the
parties cannot reach timely mutual agreement on any matter in the administration
of this contract Bonneville shall, unless otherwise specifically provided for in
subsection (b) below and, to the extent necessary for its continued performance,
make a determination of such matter without prejudice to the rights of the other
party. Such determination shall not constitute a waiver of any other remedy
belonging to the Contractor.

     (b) The questions of fact stated below shall be subject to arbitration.
Other questions of fact under this contract may be submitted to arbitration upon
written mutual agreement of the parties. The party calling for arbitration shall
serve notice in writing upon the other party, setting forth in detail the
question or questions to be arbitrated and the arbitrator appointed by such
party. The other party shall, within 10 days after the receipt of such notice,
appoint a second arbitrator, and the two so appointed shall choose and appoint a
third. In case such other party fails to appoint an arbitrator within said 10
days, or in case the two so appointed fail for 10 days to agree upon and appoint
a third, the party calling for the arbitration, upon 5 days' written notice
delivered to the other party, shall apply to the person who at the time shall be
the presiding judge of the United States Court of Appeals for the Ninth Circuit
for appointment of the second and third arbitrator, as the case may be.

     The determination of the question or questions submitted for arbitration
shall be made by a majority of the arbitrators and shall be binding on the
parties. Each party shall pay for the services and expenses of the arbitrator
appointed by or for it, for its own attorney fees, and for compensation for its
witnesses or consultants. All other costs incurred in connection with the
arbitration shall be shared equally by the parties thereto.

     The questions of fact to be determined as provided in this section shall be
limited to:

          (1) the determination of the measurements to be made by the parties
     hereto pursuant to section 4;

          (2) the correction of the measurements to be made pursuant to section
     7;

                                        9

          (3) the duration of the interruption or equivalent interruption in
     section 14;

          (4) whether changes in conditions mentioned in section 19 have
     occurred;

          (5) whether the changes mentioned in section 30 were made "promptly";

          (6) whether an increase or decrease in load or change in load factor
     mentioned in section 32 is unusual;

          (7) any issue which both parties agree is an issue of fact mentioned
     in sections 30, 31, and 34;

          (8) the occurrence of an abnormal nonrecurring demand and the amount
     and time thereof;

          (9) whether a party has complied with section 34(b); and

          (10) the acceptable level of harmonics for purposes of section 35.

     21. Contract Work Hours and Safety Standards.

     This contract, if and to the extent required by applicable law and if not
otherwise exempted, is subject to the following provisions:

     (a) Overtime Requirements. No Contractor or subcontractor contracting for
any part of the contract work which may require or involve the employment of
laborers or mechanics, shall require or permit any laborer or mechanic in any
workweek in which such worker is employed on such work to work in excess of 8
hours in any calendar day or in excess of 40 hours in such workweek unless such
laborer or mechanic receives compensation at a rate not less than one and
one-half times such worker's basic rate of pay for all hours worked in excess of
eight hours in any calendar day or in excess of 40 hours in such workweek, as
the case may be.

     (b) Violation; Liability for Unpaid Wages; Liquidated Damages. In the event
of any violation of the provisions of subsection (a), the Contractor and any

     (e) Records. The Contractor shall maintain payroll records containing the
information specified in 29 CFR 516.2(a). Such records shall be preserved for 3
years from the completion of the contract.

     22. Convict Labor. In connection with the performance of work under this
contract, the Contractor agrees, if and to the extent required by applicable law
or if not otherwise exempted, not to employ any person undergoing sentence of
imprisonment except as provided by Public Law 89- 176, September 10, 1965 (18
U.S.C. 4082(c)(2)) and Executive Order 11755, December 29, 1973.

     23. Equal Employment Opportunity. During the performance of this contract,
if and to the extent required by applicable law or if not otherwise exempted,
the Contractor agrees as follows:

     (a) The Contractor will not discriminate against any employee or applicant
for employment because of race, color, religion, sex, or national origin. The
Contractor will take affirmative action to ensure that applicants are employed,
and that employees are treated during employment, without regard to their race,
color, religion, sex, or national origin. Such action shall include, but not be
limited to, the following: employment, upgrading, demotion or transfer;
recruitment or recruitment advertising; layoff or termination; rates of pay or
other forms of compensation; and selection for training, including
apprenticeship. The Contractor agrees to post in conspicuous places, available
to employees and applicants for employment, notices to be provided by Bonneville
setting forth the provisions of the Equal Opportunity clause.

     (b) The Contractor will, in all solicitations or advertisements for
employees placed by or on behalf of the Contractor, state that all qualified
applicants will receive consideration for employment without regard to race,
color, religion, sex, or national origin.

     (c) The Contractor will send to each labor union or representative of

and relevant orders of the Secretary of Labor, or pursuant

                                       11

thereto, and will permit access to said Contractor's books, records, and
accounts by Bonneville and the Secretary of Labor for purposes of investigations
to ascertain compliance with such rules, regulations, and orders.

     (f) In the event of the Contractor's noncompliance with the Equal
Opportunity clause of this contract or with any of such rules, regulations, or
orders, this contract may be cancelled, terminated, or suspended in whole or in
part and the Contractor may be declared ineligible for further Government
contracts in accordance with procedures authorized in Executive Order No. 11246
of September 24, 1965, and such other sanctions may be imposed and remedies
invoked as provided in Executive Order No. 11246 of September 24, 1965, or by
rule, regulation, or order of the Secretary of Labor, or as otherwise provided
by law.

     (g) The Contractor will include the provisions of paragraphs (a) through
(f) in every subcontract or purchase order unless exempted by rules,
regulations, or orders of the Secretary of Labor issued pursuant to Section 204
of Executive Order No. 11246 of September 24, 1965, so that such provisions will
be binding upon each subcontractor or vendor. The Contractor will take such
action with respect to any subcontract or purchase order as Bonneville may
direct as a means of enforcing such provisions, including sanctions for
noncompliance. In the event the Contractor becomes involved in, or is threatened
with, litigation with a subcontractor or vendor as a result of such direction by
Bonneville, the Contractor may request the Government to enter into such
litigation to protect the interests of the Government.

     24. Additional Provisions. The Contractor agrees to comply with the clauses
for Government contracts contained in the following statutes, Executive Orders,

of this contract, and the parties will cooperate in exchanging such additional
information as may be reasonably useful for their respective operations.

     26. Assignment of Contract. This contract shall inure to the benefit of,
and shall be binding upon the respective successors and assigns of the parties
to this contract. Such contract or any interest therein shall not be transferred
or assigned by either party to any party other than the Government or an agency
thereof without the written consent of the other except as

                                       12

specifically provided in this section. The consent of Bonneville is hereby given
to any security assignment or other like financing instrument which may be
required under terms of any mortgage, trust, security agreement or holder of
such instrument of indebtedness made by and between the Contractor and any
mortgagee, trustee, secured party, subsidiary of the Contractor or holder of
such instrument of indebtedness, as security for bonds of other indebtedness of
such Contractor, present or future; such mortagagee, trustee, secured party,
subsidiary, or holder may realize upon such security in foreclosure or other
suitable proceedings, and succeed to all right, title, and interests of such
Contractor.

     27. Waiver of Default. Any waiver at any time by any party to this contract
of its rights with respect to any default of any other party thereto, or with
respect to any other matter arising in connection with such contract, shall not
be considered a waiver with respect to any subsequent default or matter.

     28. Notices and Computation of Time. Any notice required by this contract

     29. Interest of Member of Congress. No Member of, or Delegate to Congress,
or Resident Commissioner shall be admitted to any share or part of this contract
or to any benefit that may arise therefrom, but this provision shall not be
construed to extend to this contract if made with a corporation for its general
benefit.

            APPLICABLE ONLY IF TRANSFEREE IS A PARTY TO THIS CONTRACT
            ---------------------------------------------------------

     30. Balancing Phase Demands. If required by the Transferor at any time
during the term of this contract, the Transferee shall promptly make such
changes as are necessary on its system to balance the phase currents at any
Point of Delivery so that the current of any one phase shall not exceed the
current on any other phase at such point by more than 10 percent.

     31. Adjustment for Unbalanced Phase Demands. If the Transferee fails to
promptly make the changes mentioned in section 30, the Transferor may, after
giving written notice one month in advance, determine that the Measured Demand
of the Transferee at the Point of Delivery in question during each month
thereafter, until such changes are made, is equal to the product obtained by
multiplying by three the largest of the Integrated Demands on any phase adjusted
as appropriate to such point during such month.

     32. Changes in Requirements or Characteristics. The Transferee will,
whenever possible, give reasonable notice to the Transferor of any unusual
increase or decrease of its demands for electric power and energy on the
Transferor's system, or of any unusual change in the load factor or power factor
at which the Transferee will take delivery of electric power and energy under
this contract.

     33. Inspection of Facilities. Each party may for any reasonable purpose
under this contract inspect the other party's electric installation at any
reasonable time. Such inspection, or failure to inspect, shall not render

                                       13

such party, its officers, agents, or employees, liable or responsible for any
injury, loss, damage, or accident resulting from defects in such electric
installation, or for violation of this contract. The inspecting party shall
observe written instructions and rules posted in facilities and such other
necessary instructions or standards for inspection as the parties agree to. Only
those electric installations used in complying with the terms of this contract
shall be subject to inspection.

     34. Electric Disturbances.

     (a) For the purposes of this section, an electric disturbance is any
sudden, unexpected, changed, or abnormal electric condition occurring in or on
an electric system which causes damage.

     (b) Each party shall design, construct, operate, maintain and use its
electric system in conformance with accepted utility practices:

          (1) to minimize electric disturbances such as, but not limited to, the
     abnormal flow of power which may damage or interfere with the electric
     system of the other party or any electric system connected with such other
     party's electric system; and

          (2) to minimize the effect on its electric system and on its customers
     of electric disturbances originating on its own or another electric system.

     (c) If both parties to this contract are parties to the Western
Interconnected Electric System Agreement, their relationship with respect to
system damages shall be governed by that Agreement.

     (d) During such time as a party to this contract is not a party to the
Agreement Limiting Liability Among Western Interconnected Systems, its relations
with the other party with respect to system damages shall be governed by the
following sentence, notwithstanding the fact that the other party may be a party
to said Agreement Limiting Liability Among Western Interconnected Systems. A
party to this contract shall not be liable to the other party for damage to the
other party's system or facilities caused by an electric disturbance on the
first party's system, whether or not such electric disturbance is the result of
negligence by the first party, if the other party has failed to fulfill its
obligations under subsection (b)(2) above.

     (e) If one of the parties to this contract is not a party to the Agreement
Limiting Liability Among Western Interconnected Systems, each party to this
contract shall hold harmless and indemnify the other party, its officers and
employees, from any claims for loss, injury, or damage suffered by those to whom
the first party delivers power not for resale, which loss, injury or damage is
caused by an electric disturbance on the other party's system, whether or not
such electric disturbance results from the negligence of such other party, if
such first party has failed to fulfill its obligations under subsection (b)(2)
above, and such failure contributed to the loss, injury or damage.

                                       14

     (f) Nothing in this section shall be construed to create any duty to, any
standard of care with reference to, or any liability to any person not a party
to this contract.

     35. Harmonic Control. Each party shall design, construct, operate, maintain
and use its electric facilities in accordance with good engineering practices to
reduce to acceptable levels the harmonic currents and voltages which pass into
the other party's facilities. Harmonic reductions shall be accomplished with
equipment which is specifically designed and permanently operated and maintained
as an integral part of the facilities of the party which owns the system on
which harmonics are generated.

          APPLICABLE ONLY IF TRANSFEREE IS NOT A PARTY TO THIS CONTRACT
          -------------------------------------------------------------

     36. Protection of the Transferor. Protection is or will be afforded to
Bonneville or its Transferor under such of the following provisions and
conditions as are specified in each contract executed or to be executed by
Bonneville and each third party Transferee named in this contract: the power
factor clause of the applicable Bonneville Wholesale Rate Schedule and the
subject matter set forth in the General Contract Provisions under the following
titles, namely:

     Adjustment for Unbalanced Phase Demands; Uncontrollable Forces; Continuity
of Service; Changes in Demands or Characteristics; Electric Disturbances;
Harmonic Control; Balancing Phase Demands; Permits; Ownership of Facilities; and
Inspection of Facilities.

           RELATING TO RURAL ELECTRIFICATION ADMINISTRATION BORROWERS
           ----------------------------------------------------------

     37. Approval of Contract. If the Contractor borrows from the Rural
Electrification Administration or any other entity under an indenture which
requires the lender's approval of contracts, this contract and any amendment
thereto shall not be binding on the parties thereto if they are not approved by
the Rural Electrification Administration or such other entity. The Contractor
shall notify Bonneville of any such entity. If approval is given, such contract
or amendment shall be effective at the time stated therein.

                 APPLICABLE ONLY IF BONNEVILLE IS THE TRANSFEROR
                 -----------------------------------------------

     38. Equitable Adjustment of Rates.

     (a) Bonneville shall establish, periodically review and revise rates for
the wheeling of electric power and/or energy pursuant to the terms of this
contract. Such rates shall be established in accordance with applicable law.

     (b) As used in this section, the words "Rate Adjustment Date" shall mean
any date specified by Bonneville in a notice of intent to file revised rates as
published in the Federal Register; provided, however, that such date shall not
occur sooner than (1) nine months from the date that such notice of intent is
published; or (2) twelve months from any previous Rate Adjustment Date. By
giving written notice to the Contractor 45 days prior to such Rate Adjustment
Date, Bonneville may delay such Rate Adjustment Date for up to 90 days if
Bonneville determines either that the revenue level of the proposed rates

                                       15

differs by more than five percent from the revenue requirements indicated by
most recent repayment studies entered in the hearings record or that external
events beyond Bonneville's control will prevent Bonneville from meeting such
Rate Adjustment Date. Bonneville may cancel a notice of intent to file revised
rates at any time (1) by written notice to the Contractor; or (2) by publishing
in the Federal Register a new notice of intent to file revised rates which
specifically cancels a previous notice.

     (c) The Contractor shall pay Bonneville for the service made available
under this contract during the period commencing on each Rate Adjustment Date
and ending at the beginning of the next Rate Adjustment Date at the rate
specified in any rate schedule available at the beginning of such period for
service of the class, quality, and type provided for in this contract, and in
accordance with the terms thereof, and of the General Transmission Rate Schedule
Provisions, if any, as changed with, incorporated in or referred to in such rate

          allowed by section 4 of this Agreement shall be subject to
          Bonneville's precedent and policy of providing transmission capacity
          to its direct service customers in excess of their Contract Demand.

                                        4

2.   REQUESTS FOR TRANSMISSION SERVICE.

     2.1  Service to be Provided. Upon request by Customer and subject to the
          terms of this Agreement, Bonneville shall provide Transmission
          Services to Customer from its Available Transmission Capacity on its
          Existing Facilities, or from Incremental Facilities where necessary,
          to Customer on the same basis that Bonneville provides such services
          to similarly-situated entities eligible for FERC-ordered service under
          FPA sections 211 and 212.

     2.2  Request for Service. Customer shall provide to Bonneville information
          regarding its request for transmission service, consistent (to the
          extent applicable) with either the FERC's then-current policy
          regarding such request (as currently embodied in its "Policy Statement
          Regarding Good Faith Requests for Transmission Services") or as
          otherwise mutually agreed. A request for transmission services which
          is consistent with this subsection shall be deemed a "Good Faith
          Request" for transmission services for purposes of this Agreement.

     2.3  Response to Request for Transmission Service.

          2.3.1 Bonneville shall respond to a request for transmission services
                from Customer in a manner consistent with responses to Good
                Faith Requests under section 212 of the FPA and FERC's
                then-current policies (as presently embodied in its "Policy
                Statement Regarding Good Faith Requests for Transmission
                Services").

          2.3.2 Bonneville may elect to provide the requested transmission
                service without further study, or may elect to conduct a study,
                including any environmental studies, if such are reasonably
                required by statute to determine:

                                        5

               (i)  whether Bonneville has sufficient Available Transmission
                    Capacity to provide the requested service initially and for
                    the full term of the request; and

               (ii) what Incremental Facilities, if any, are required to
                    accommodate the requested service.

               If Bonneville and Customer agree, such study may be conducted by
               a third party; provided, however, Bonneville shall retain the
               authority to accept or reject the study's conclusions.
               Bonneville's reasonable study costs shall be billed to and paid
               by Customer based upon Bonneville's estimate of such costs. Any
               reconciliation for over or underpayment shall be done upon
               completion of the study work. Such study shall be completed
               within a reasonable time period consistent with FERC's
               then-current policies. Failing agreement between Bonneville and
               Customer on a reasonable period of time for and scope of such
               studies, the dispute resolution procedures may be invoked by
               either Party. Bonneville shall be responsible for conducting the
               study with participation and input from Customer. The results of
               the study, to the extent Customer has not requested confidential
               treatment, shall be made available to the Customer and to any
               other DSI or Member of the Northwest RTA, provided that such
               other DSI or Member reimburses Customer for a reasonable share of
               its costs.

          2.3.3 Subject to the requirements of the National Environmental Policy
                Act or other applicable environmental laws, if Bonneville is
                able to provide the requested transmission service without
                further study or if the study demonstrates that the requested
                service can be provided using Existing Facilities, then
                Bonneville shall promptly tender amendments to this contract to
                Customer and take all other actions reasonably necessary to

                                        6

                effectuate service.

     2.4  Requests Requiring Upgrades, Additional Facilities or
          Interconnections.

          2.4.1 If Bonneville concludes, based on a study performed pursuant to
                subsection 2.3.2, that Bonneville does not have sufficient
                Available Transmission Capacity to provide the requested service
                initially or for the term of the request, then Bonneville's
                study shall include at a minimum: (i) a detailed description of
                the Incremental Facilities which are necessary to provide the
                requested service; (ii) the estimated cost of and cash flow
                requirements for installing the Incremental Facilities; (iii)
                the estimated time necessary to build the Incremental
                Facilities, including the estimated time required for
                environmental studies, licensing and regulatory approvals, (iv)
                the estimated incremental capacity added to the transmission
                system by the Incremental Facilities; and (v) whether Customer
                will be expected or required to contribute capital in connection
                with installing the Incremental Facilities. If requested,
                Bonneville will also provide a list of any other requests or
                Bonneville forecasted uses that contributed to the insufficiency
                of Available Transmission Capacity.

          2.4.2 If Bonneville's study demonstrates a need for a transmission
                Interconnection with another entity, then Bonneville shall make
                a good faith effort to arrange a joint study with the other
                entity to evaluate the impact of such an Interconnection.

          2.4.3 If Bonneville's study demonstrates a need for and the
                feasibility of building Incremental Facilities and if Customer
                elects to proceed with its request for transmission services,
                then Bonneville shall be obligated to build the Incremental
                Facility and provide the requested service; provided that
                Bonneville's obligation to build and provide service is subject
                to applicable

                                        7

                law.  Bonneville shall provide notice of the project to all
                other DSIs and to the manager of the Northwest RTA.

3.   PRICING.

     Pricing of Transmission Services by Bonneville to integrate Customer's
     Resource to its load under this Agreement shall be pursuant to IR-93 and
     its successor. If Bonneville offers other Transmission Services, pricing
     for such services shall be at the rates applicable to other users of the
     same services.

4.   PURCHASE AND RESALE SERVICES.

     Bonneville and Customer acknowledge that in some instances, an arrangement
     in which Bonneville purchases power for resale to Customer may be
     preferable to Bonneville wheeling non-federal power to Customer. Therefore,
     Bonneville shall make best efforts to purchase power, energy or other
     energy services, as specified by Customer as to supplier, amount, term,
     shape, and other criteria, and resell such power, energy or other energy
     services to Customer for Customer's own use at a price equal to
     Bonneville's purchase costs for the power plus Bonneville transmission
     charges that would have been applicable if Customer had directly purchased
     such power, energy or other energy services. Bonneville may also impose a
     reasonable brokerage fee for this service.

5.   TRANSMISSION ON NON-FEDERAL SYSTEMS.

     Bonneville shall make best efforts to request and purchase transmission
     services identified by Customer, on Customer's behalf, from Northwest RTG
     members, Westwide RTG members, or from any transmitting utility under
     sections 211 and 212 of the Federal Power Act. Customer shall reimburse
     Bonneville for all of the costs incurred in complying with this provision.

                                        8

6.   DISPUTE RESOLUTION.

     6.1  Scope of Dispute Resolution. The scope of dispute resolution under
          this Agreement shall include all disputes arising under this
          Agreement, including but not limited to, disputes concerning amounts
          and location of Available Transmission Capacity; need for and costs of
          Incremental Facilities and interconnection facilities; costs, prices,
          and terms and conditions of requested transmission services and
          interconnection facilities; and estimates of the nature, extent, total
          cost, schedule, and proposed allocations of costs associated with
          studies, including environmental analyses, proposed in response to a
          request for service; and including, unless expressly waived, disputes
          arising under transmission agreements requested, offered or signed
          pursuant to this Agreement.

     6.2  Preconditions to Arbitration.

          6.2.1 Each Party shall use best efforts to settle all disputes arising
                under this Governing Agreement. In the event any such dispute is
                not settled, any disputing Party may request in writing that the
                Manager of the Northwest RTA (or alternatively, the head of the
                Northwest Power Pool) appoint an impartial facilitator to aid
                the disputing Parties in reaching a mutually acceptable
                resolution to the dispute; such appointment shall be made within
                ten days of receipt of the request. The facilitator and
                representatives of the disputing Parties with authority to
                settle the dispute shall meet within 21 days after the
                facilitator has been appointed to attempt to negotiate a
                resolution of the dispute. Settlement offers shall not be
                admissible in any subsequent dispute resolution process or in
                any other forum. With the consent of all disputing Parties,
                resolution may include referring the matter to a technical body
                (such as the Northwest Power Pool Transmission Planning
                Committee) for resolution or an advisory opinion.

                                        9

          6.2.2 If the disputing Parties have not succeeded in negotiating a
                resolution of the dispute within 30 days after first meeting
                with the facilitator or if the facilitator is not appointed
                within ten days pursuant to subsection 6.2.1, such Parties shall
                be deemed to be at an impasse and any such disputing Party may
                commence the dispute resolution process by submitting a written
                notice to the other Party.

     6.3 Arbitration Process.

          6.3.1 Within 14 days of a disputing Party's request that the
                arbitration process be commenced, each disputing Party shall
                submit a statement in writing to the other disputing Party,
                which statement shall set forth in reasonable detail the nature
                of the dispute, the issues to be arbitrated, and the proposed
                Award sought through such arbitration proceedings. To the extent
                the disputing Parties do not agree on the terms of a requested
                contract for Interconnection or Transmission Services, each
                submittal shall include proposed contract language for those
                issues in dispute.

          6.3.2 Within ten days following the submission of their statements,
                the disputing Parties shall select an Arbitrator who shall be
                familiar with and knowledgeable about the policies and criteria
                used in the Northwest Interconnected Area transmission systems
                and regulatory requirements. If the disputing Parties cannot
                agree upon an Arbitrator, the disputing Parties shall take turns
                striking names from a list of ten qualified individuals supplied
                by the Northwest RTA Manager (or alternatively the head of the
                Northwest Power Pool) from the list maintained by the Northwest
                RTA Board with a disputing Party chosen by lot first striking a
                name. The last-remaining name not stricken shall be designated
                as the Arbitrator. If that individual is unable or unwilling to
                serve, the individual last stricken from

                                       10

                the list shall be designated and the process repeated until an
                individual is selected who is able and willing to serve. Absent
                the express written consent of all disputing Parties as to any
                particular individual, no person shall be eligible for selection
                as an Arbitrator who is or was, past or present, an officer,
                member of the governing body, employee of or consultant to any
                of the disputing Parties, or of an entity related to or
                affiliated with any of the disputing Parties, or whose interests
                are otherwise affected by the matter to be arbitrated. Any
                individual designated as an Arbitrator shall make known to the
                disputing Parties any such disqualifying relationship and a new
                Arbitrator shall be designated in accordance with the provisions
                of this subsection.

          6.3.3 The Arbitrator shall cause to be published in the Northwest RTA
                newsletter and electronic bulletin board a notice of the dispute
                with sufficient detail to inform potential intervenors of the
                disputed issues.

          6.3.4 The Arbitrator shall determine discovery procedures,
                intervention rights, how evidence shall be taken, what written
                submittals may be made, and other such procedural matters,
                taking into account the complexity of the issues involved, the
                extent to which factual matters are disputed and the extent to
                which the credibility of witnesses is relevant to a resolution
                of the dispute. Each party to the dispute shall produce all
                evidence determined by the Arbitrator to be relevant to the
                issues presented. To the extent such evidence involves
                proprietary or confidential information, the Arbitrator shall
                issue an appropriate protective order which shall be complied
                with by all Parties to the dispute. The Arbitrator may elect to
                resolve the arbitration matter solely on the basis of written
                evidence and arguments.

          6.3.5 The Arbitrator shall grant intervention only to Parties that
                have a commercial power or transmission interest in the dispute.
                Intervening

                                       11

                Parties shall have the same procedural rights as Disputing
                Parties to the dispute. "Parties" refers to both Disputing
                Parties and Intervening Parties. Absent the agreement to the
                contrary of all disputing Parties, no entity shall be permitted
                to intervene unless, as a condition of its intervention, it
                agrees to be bound by these dispute resolution provisions,
                including the provisions related to deference on appeal set
                forth in subsection 6.6.4.

          6.3.6 The Arbitrator shall consider all issues underlying a dispute
                including, if relevant, whether Bonneville's reliability
                criteria, standards, guidelines and operating procedures are
                reasonably consistent with Prudent Utility Practice, after
                giving consideration to consistently applied regional or
                national reliability standards, guidelines or criteria;
                provided, that Bonneville's reliability criteria, standards, and
                guidelines, and operating procedures for maintaining system
                reliability which were in effect and in writing as of July 1,
                1993, or that are consistent with the provisions of reliability
                criteria, standards, guidelines, and operating procedures of the
                North American Electric Reliability Council and the WSCC which
                govern the planning, design, and operation of Members'
                transmission systems, but not the applicability, consistent
                application or interpretation of such criteria, standards,
                operating procedures and guidelines in regard to a particular
                request, shall be afforded a rebuttable presumption of
                reasonableness and consistency with Prudent Utility Practice by
                the Arbitrator. Bonneville's reliability criteria, standards,
                guidelines and operating procedures shall be consistently
                applied by Bonneville to its own use of its system and to
                Customer's request to use such system pursuant to a request for
                interconnection or Transmission Services.

          6.3.7 The Arbitrator shall take evidence submitted by the Parties in
                accordance with procedures established by the Arbitrator and may
                request additional information, including the opinion of
                recognized technical bodies. Parties

                                       12

                shall be afforded a reasonable opportunity to rebut any such
                additional information.

     6.4  Substantive Standards and Decision. The Arbitrator shall apply to any
          dispute arising from a request for service the standards that FERC
          would apply to a request for FERC ordered service under FPA sections
          211 and 212. As soon as practicable, but in no event later than 115
          days of his or her selection as Arbitrator, the Arbitrator shall
          select, by written notice to the Parties, the proposed Award of a
          disputing party which best meets the terms and intent of this
          Agreement and conforms with the FPA and FERC's then-applicable
          standards and policies for FERC-ordered service; provided, however, if
          the Arbitrator concludes that no proposed Award is consistent with
          this Governing Agreement, the FPA, and FERC's then-applicable
          standards and policies, or addresses all issues in dispute, the
          Arbitrator shall specify how each proposed Award is deficient and
          request that the Parties submit within twenty (20) days new proposed
          Awards that cure the deficiencies stated by the Arbitrator. A written
          decision, including specific findings of fact, explaining the basis
          for the Award shall be provided by the Arbitrator. Awards will be
          based only on the evidence on the record before the Arbitrator. The
          decision shall be published in the NWRTA newsletter or on the
          electronic bulletin board. No Award that is not appealed shall be
          deemed to be precedential in any other arbitration related to a
          different dispute.

     6.5  Compliance and Costs.

          6.5.1 Immediately upon the decision by the Arbitrator, the disputing
                Parties shall take whatever action is required to comply with
                the selected Award to the extent the selected Award does not
                require regulatory action and no party seeks appeal. To the
                extent the Award requires local or federal approval or
                regulatory action, Bonneville shall promptly submit and support
                that

                                       13

                portion of the Award with the appropriate authority. Any and all
                costs associated with the arbitration (not including the
                Parties' costs associated with attorney costs and expert witness
                fees) shall be borne by the Party or Parties whose proposed
                Award was not selected, unless the Parties agree to an alternate
                method of allocating costs.

     6.6  Bonneville Rate Proceedings. In case of a dispute arising under this
          Agreement concerning a Bonneville rate for requested Interconnection
          or Transmission Services ("Bonneville Rate Issue Dispute"):

          6.6.1 Except as otherwise provided in this subsection, this subsection
                6.6 shall apply to a Bonneville Rate Issue Dispute in lieu of
                subsection 6.3, 6.4, 6.5 of this Agreement; provided, that if
                Bonneville has by Federal Register notice initiated a hearing
                under subsection 7(i) of the Pacific Northwest Electric Power
                Planning and Conservation Act (Northwest Power Act) to
                establish, or to review and revise, a rate or rates of general
                applicability for FERC- ordered transmission services, and the
                Bonneville Rate Issue Dispute involves the appropriateness or
                application of such rate or rates to the Customer's request for
                Bonneville Transmission Services, then for purposes only of
                Customer's request for Bonneville Transmission Services a
                separate subsection 7(i) proceeding shall be held in accordance
                with the procedures of this subsection 6.6 to resolve that
                particular Bonneville Rate Issue Dispute unless the Arbitrator
                determines that (1) the separate 7(i) proceeding would frustrate
                the ongoing 7(i) proceeding and (2) resolution of the Bonneville
                Rate Issue Dispute in the ongoing 7(i) proceeding would not
                materially frustrate the Customer's need for an expeditious
                decision.

          6.6.2 Where the rate would have been subject to review and
                determination by FERC under subsection 212(i)(1) of the FPA if
                the rate dispute and any related good faith dispute over
                Transmission Services had been timely

                                       14

                brought before FERC by an entity eligible to request
                FERC-ordered service under subsection 211 of the FPA, then
                pricing of Interconnection or Transmission Service by Bonneville
                in response to Customer request shall conform to subsection
                212(i)(1)(ii) of the FPA and then-applicable standards and
                policies of FERC.

          6.6.3 A hearing on a Bonneville Rate Issue Dispute shall be held which
                comports in all respects with subsection 7(i) of the Northwest
                Power Act and other applicable requirements of Federal law,
                including any applicable requirements of the National
                Environmental Policy Act, with the addition that:

                (i) following compliance with the preconditions to arbitration
                    set forth in subsection 6.2 of this Governing Agreement, and
                    within 14 days of a disputing Party's ensuing request that
                    the hearing process be commenced, each disputing Party shall
                    submit a statement in writing to the other disputing Party,
                    which statement shall set forth in reasonable detail the
                    nature of the Bonneville Rate Issue Dispute, the issues to
                    be raised in the hearing, and the proposed rate(s) sought
                    through such hearing;

               (ii) Bonneville shall within 14 days of its receipt of the
                    disputing Party's written statement prepare and submit for
                    publication a Federal Register notice that in addition to
                    meeting the requirements of Northwest Power Act subsection
                    7(i)(1), also sets forth the statements or notifies the
                    public of their availability;

              (iii) the Hearing Officer/Arbitrator (hereafter Hearing Officer)
                    shall be selected as specified in subsection 6.3.2 of this
                    Governing Agreement, which selection shall be officially
                    recognized by

                                       15

                    Bonneville;

               (iv) with the exception of any legally required process for
                    taking participant comments, the hearing shall be held in
                    Portland, Oregon, and in the Bonneville Rates Hearing Room
                    if available, unless an alternative location is agreed to by
                    all Parties to the hearing;

                (v) the Hearing Officer shall comport with subsections 6.3.4,
                    6.3.6 and 6.3.7 of this Governing Agreement, unless
                    inconsistent with the procedural provisions of subsection
                    7(i) of the Northwest Power Act or the National
                    Environmental Policy Act;

               (vi) the Hearing Officer shall, unless violative of subsection
                    7(i) of the Northwest Power Act or the National
                    Environmental Policy Act, conduct the hearing in a manner
                    calculated to ensure that no more than 115 days elapses from
                    the date of the publicly noticed pre-hearing conference to
                    the date of the Administrator's final decision pursuant to
                    subsection 7(i)(5) of the Northwest Power Act;

              (vii) the Hearing Officer shall, unless the Hearing Officer
                    becomes unavailable, make a recommended decision to the
                    Administrator that (a) best meets the terms and intent of
                    this Governing Agreement, subsection 212(i) of the FPA and
                    FERC's then-applicable standards and policies for
                    FERC-ordered service, and (b) sets forth the Hearing
                    Officer's findings and conclusions, and the reasons or basis
                    thereof, on all material issues of fact, law, or discretion
                    presented on the record;

             (viii) in the case of rates described in subsection 6.6.2 above,
                    the Administrator shall afford deference to the Hearing
                    Officer's factual

                                       16

                    findings and determination of issues not of first impression
                    (i.e., matters previously decided by FERC or a court of
                    competent jurisdiction in cases involving comparable facts
                    and circumstances); and

               (ix) the Administrator's final decision under subsection 7(i)(5)
                    of the Northwest Power Act shall also set forth the reasons
                    for reaching any findings and conclusions which may differ
                    from those of the Hearing Officer, based on the hearing
                    record and the law.

          6.6.4 FERC Appeal. Bonneville shall file its final rates decision with
                FERC in accord with existing provisions of law and regulation. A
                disputing party to an arbitration may apply to FERC to appeal or
                protest that aspect of any Award relating to Bonneville's rate.
                Any appeal to FERC shall be based solely upon the record
                assembled by the Arbitrator, provided, however, that any order
                by an Arbitrator excluding material from the arbitration record
                or which is alleged to violate due process may be explicitly
                appealed to FERC. Bonneville and the Customer, in the case of
                Bonneville rates described in subsection 6.6.2 above, intend
                that FERC should afford deference to the Hearings Officer
                factual findings and determinations of issues not of first
                impression (i.e., matters previously decided by FERC or a court
                of competent jurisdiction in cases involving comparable facts
                and circumstances).

     6.7  Appeal to Claims Court. A disputing party to an arbitration may apply
          to the U.S. Claims Court to hear an appeal of that aspect of any Award
          relating to terms and conditions of requested service or a breach of
          this Agreement. Upon finding that any terms and conditions are
          inconsistent with this Agreement or that Bonneville has breached this
          Agreement, the Claims Court shall remand to the Arbitrator for any
          further determinations and decisions.
