                            -4-





    







           6.2 The Transmission Service Entitlement for each Plant shall be
the Maximum Transmission Service Entitlement for such Plant specified in
Exhibit[s] II, Transmission Service, or any subsequent Plant Amendments, or
such lesser amount as may be established as follows. Beginning on the Date of
Initial Service for each Plant, Producer shall be entitled to specify a
Transmission Service Entitlement by advance written notice given to IID's
Authorized Representative at least thirty (30) days prior to the Date of
Initial Service. The Transmission Service Entitlement to be provided by IID
subsequent to the Date of Initial Service may be adjusted at six (6) month
intervals thereafter until two (2) years after the Date of Initial Service for
such Plant (the "Trial Period"). Such adjustments shall be made by having
Producer's Authorized Representative give IID's Authorized Representative a
ninety (90) day advance written notice as to the adjustment required.
Beginning two (2) years after the Date of Initial Service for such Plant,
Producer shall be entitled to specify a Transmission Service Entitlement for
each successive two-year period during the remaining term of this Agreement by
written notice from Producer's Authorized Representative to IID's Authorized
Representative given at least ninety (90) days prior to the beginning of each
two-year period.
           6.3 The Transmission Service Entitlement selected by Producer for
each Plant in accordance with Section 6.2 may be any amount which is less than
or equal to the Maximum Transmission Service Entitlement for such Plant
specified in Exhibit[s] II, Transmission Service and in any subsequent Plant
Amendments,


                            -5-





    






provided, however, that the following shall apply to each Plant after the
Trial Period for such Plant has elapsed.
                6.3.1 If (i) the sum of the Transmission Service Entitlements
for all Plants which are no longer in their Trial Periods is less than the sum
of the Maximum Transmission Service Entitlements for such Plants, as shown in
Exhibit[s] II, Transmission Service and in any subsequent Plant Amendments,
(the "Aggregate Maximum Transmission Service Entitlement"), and (ii) provided
that IID requires additional capacity for transmitting electric power to
Edison's transmission system for another person (or, following the Credit
Installment Period as defined in the Funding and Construction Agreement, for
itself) and (iii) IID's use of such required capacity would be in conflict
with Producer's right as provided herein to increase the sum of the
Transmission Service Entitlements for such Plants to the Aggregate Maximum
Transmission Service Entitlement, then IID shall so notify Producer in
writing, specifying in such notice the portion, expressed in megawatts (MW),
of the excess of the Maximum Transmission Service Entitlement over the
Transmission Service Entitlement for each such Plant which it desires to use
as stated above. Producer shall have ninety (90) days after receipt of IID's
notice to notify IID in writing that it desires to increase the Transmission
Service Entitlements of such Plants. To the extent that Producer does not
elect to increase the Transmission Service Entitlement of each such Plant up
to the Maximum Transmission Service Entitlement for such Plant, IID shall be
entitled to use such unclaimed capacity to satisfy the


                            -6-





    






transmission requirements specified in its notice to Producer, and to the
extent that IID does so, Producer shall thereafter be foreclosed from
increasing the Transmission Service Entitlement for such Plant in a manner
which would conflict with such usage by IID.
                6.3.2 IID shall treat Producer and each other person who has
entered into a transmission service agreement similar in substance to this
Agreement in a fair and nondiscriminatory manner in requesting additional
transmission capacity as provided in this Section 6.3. Without limiting the
generality of the foregoing, IID shall request additional transmission
capacity from Producer and such other persons on a pro rata basis, in
proportion to the Aggregate Maximum Transmission Service Entitlement for each
person less the sum of the Transmission Service Entitlements for each of such
persons' generating plants which is no longer in a Trial Period.
           6.4 In the event that the Original Capacity Nomination designated
by Producer (or the Participant associated with Producer) is adjusted pursuant
to Section 3.07 of the Funding and Construction Agreement, the Parties agree
to amend this Agreement in such a way that the sum of the Maximum Transmission
Service Entitlements for all Plants hereunder is equal to such Original
Capacity Nomination as so adjusted. As used in this Section 6.4, the terms
Original Capacity Nomination and Participant shall have the meanings assigned
to them in Article I of the Funding and Construction Agreement.


                            -7-





    





                6.5 IID reserves the right to interrupt or curtail the
transmission service provided hereunder as follows:
                6.5.1 If the Operating Transmission Capability is reduced to
less than Normal Transmission Capacity from a Point of Receipt to a Point of
Delivery, and when continuity of service within IID's service area is not
being jeopardized, IID may curtail the transmission service currently being
provided from such Point of Receipt to such Point of Delivery, to an amount
"A" determined by the following formula:

A = Operating Transmission Capability     x    Transmission Service
       Normal Transmission Capacity                Entitlement

                The transmission service for each Plant affected
shall be curtailed by multiplying the Transmission Service Entitlement in
accordance with Exhibit[s] II, Transmission Service and in any subsequent
Plant Amendments by the same percentage (expressed as a decimal) as used in
the determination of "A." However, any such curtailment shall occur only after
IID has made all reasonable efforts to eliminate the cause of the reduction in
Operating Transmission Capability, and IID shall then employ reasonable
efforts to eliminate expeditiously the cause of said reduction.
                6.5.2 If continuity of service within IID's control area is
being jeopardized, as determined by IID in its sole judgment, IID may
interrupt or curtail the transmission service provided hereunder to the extent
necessary to avoid or eliminate such jeopardy; provided that (i) such
interruptions or curtailments may be made so that IID may fully utilize all
generating resources owned by it or available to it under


                            -8-





    







contract in order to avoid damage to IID's electrical system caused by
overloading, (ii) such interruption or curtailment shall occur only after IID
has made all reasonable efforts to avoid or eliminate such jeopardy and (iii)
to the extent feasible any curtailment of transmission service provided
hereunder from a Point of Receipt to a Point of Delivery shall be made in
accordance with the formula set forth in Section 6.5.1.
           6.6 If IID's efforts do not avoid or eliminate such jeopardy, the
Parties shall endeavor to develop some other arrangement to avoid or eliminate
such jeopardy and minimize the effects of IID's interruption or curtailment on
both parties.
           6.7 In the event of any curtailments or interruptions made pursuant
to Section 6.5.1 or Section 6.5.2, Producer shall, immediately after being
orally notified by IID, reduce the electrical output of the Plants by the
amounts requested by IID.
           6.8 The transmission service to be provided by IID and purchased by
Producer for each Plant shall not exceed the Transmission Service Entitlement
for that Plant.
           6.9 Subject to Section 6.5, IID shall, during the periods that IID
has agreed to provide the transmission service at the specified Transmission
Service Entitlements, accept hourly scheduled energy deliveries at each Point
of Receipt and simultaneously deliver the same amount of energy (less
transmission losses as provided herein) at the Point(s) of Delivery mutually
agreed upon by the Parties' dispatchers and/or schedulers.


                            -9-





    






6.10 Hourly scheduled energy deliveries at each Point of Receipt shall conform
with the practices and procedures developed by the Parties' dispatchers and
schedulers and agreed to by the Authorized Representatives.
           7.   TRANSMISSION LOSSES:
           7.1 IID shall determine, by transmission power flow analysis, the
electrical losses (expressed as a percent amount of hourly scheduled energy
deliveries) associated with the electrical output from each Plant. Such
analysis shall be performed by IID at its sole expense. The initial percent
amount, for each Plant, representing the electrical losses as determined
herein shall be as specified in Exhibit[s] II, Transmission Service and in any
subsequent Plant Amendments.
           7.2 Unless otherwise agreed to by Producer's and IID's schedulers
and dispatchers, IID shall reduce the amount of all hourly scheduled energy
deliveries for Producer or Producer's account by the percent amount of such
hourly deliveries for each Plant in accordance with Exhibit[s] II,
Transmission Service and in any subsequent Plant Amendments.
           7.3 If either Party believes that there has been a significant
change in IID's electrical system and the electrical losses associated with
any Plant should be redetermined, either Party's Authorized Representative may
submit a written request to the other Party's Authorized Representative that
the electrical losses be redetermined. Following such request, a transmission
flow analysis shall be performed by IID as approved by the Authorized
Representatives and paid for by the requesting Party.


                            -10-





    







Whenever the percent amount for electrical losses is redetermined, such
percent amount shall become effective as of the first day of the month
following the date of such redetermination; provided, that such a
redetermination may be no sooner than twelve (12) months after the most recent
redetermination. Any redetermination of electrical losses made pursuant to
this Section 7 shall be based on conditions in existence at the time of such
redetermination.
           7.4 Along with the monthly billing pursuant to Section 9.1, for the
transmission service for each Plant, IID shall submit a monthly summary of
hourly scheduled energy deliveries and of electrical losses for each Plant.
           8.   CHARGES:
           8.1 For transmission service provided by IID, Producer shall pay
IID at a rate to be determined by IID pursuant to the methodologies specified
in Exhibit I.A. The initial rate is specified in Exhibit[s] II, Transmission
Service and revisions thereto will be specified in any subsequent Plant
Amendments. Any specific facility charge to Producer for connecting the
Plant(s) to the IID transmission system shall be included only in the Plant
Connection Agreement(s) between IID and Producer.
           8.2 The transmission rate shall be reviewed annually and may be
revised. Any revision of the rates shall be based on the methodologies in
Exhibit I.A and on the conditions in existence at the time of the revision.
Producer shall have the right to review any exhibits or work papers prepared
by IID to revise the rates.


                            -11-





    







           8.3 An initial monthly scheduling fee, as specified in Exhibit[s]
II, Transmission Service and revisions thereto specified in any subsequent
Plant Amendments, shall be paid by Producer to IID for those months in which
there were scheduled energy deliveries from the Plant(s). The initial
scheduling fee has been determined by IID pursuant to the methodology
specified in Exhibit I.B. The scheduling fee shall be reviewed annually and
may be revised. Any revision of the scheduling fee shall be based on the
methodology in exhibit I.B and on the conditions in existence at the time of
the revision. Producer shall have the right to review any exhibits or work
papers prepared by IID to revise the scheduling fee.
           9.   BILLING AND PAYMENT:
           9.1 IID shall render bills to Producer, beginning in the month of
the Date of Initial Service, on or before the fifteenth (15th) day of each
month for the transmission service to be provided during the month. Producer
shall pay such bills within twenty (20) days after receipt thereof.

           All payments by Producer shall be sent to:
                Imperial Irrigation District
                c/o Manager, Finance and Accounting
                P.O. Box 937
                Imperial, California  92251

           All billings by IID shall be sent to:
                Del Ranch, Ltd.
                7029 Gentry Road
                Calipatria, California  92233

           9.2  Either Party's Authorized Representative may at
any time, by advance written notice to the other Party's


                            -12-





    







Authorized Representative, change the address to which payments or billings
shall be sent.
           9.3 Bills which are not paid in full by said due date shall
thereafter bear an additional charge of one and one-half percent (1-1/2%) per
month, or the maximum legal rate of interest, whichever is less, compounded
monthly on the unpaid amount prorated by days from the due date until payment
is received by IID.
           9.4 In the event any portion of any bill is disputed, the disputed
amount shall be paid when due under protest. If the protested portion of the
payment is found to be incorrect by the Authorized Representatives, the
disputed amount shall be paid by IID to Producer, including interest at the
rate of 1-1/2% per month, or the maximum legal rate, whichever is less,
compounded monthly from the date of payment by Producer to the date the refund
check or adjusted bill is received by Producer.
           9.5 For a fractional part of a calendar month at the beginning or
end of the period for which the transmission service is provided hereunder,
the charge pursuant to Section 8.1 shall be proportionately adjusted by the
ratio of days that service is furnished by IID to Producer during such month
to the total number of days in such month.
           9.6 The charge for the transmission service pursuant to Section 8.1
shall be proportionately reduced to the extent the duration of the
interruptions or curtailments of the transmission service which may occur
pursuant to Section 6.5.1 or Section 6.5.2 exceed a cumulative total of
twenty-four (24) hours during


                            -13-





    






any calendar month based on 730 hours per month representing the full
transmission service charge. The amount of such pro rata reduction in any
month shall reflect the duration and amount of such interruptions or
curtailments which exceed said cumulative 24 hours. Such pro rata reduction
shall be reflected as a credit to Producer as soon as possible in a subsequent
monthly bill.
           9.7 The charge for the transmission service shall not be reduced if
IID can deliver, but Edison's transmission system cannot receive, the hourly
scheduled energy deliveries independent of the duration of time this condition
exists.
           10.  LIABILITY:
           10.1 Except for any loss, damage, claim, costs, charge or expense
resulting from Willful Action, neither Party (the "released Party"), its
directors or other governing body, officers or employees shall be liable to
the other Party for any loss, damage, claim, cost, charge, or expense of any
kind or nature incurred by the other Party (including direct, indirect or
consequential loss, damage, claim, cost, charge or expense; and whether or not
resulting from the negligence of a Party, its directors or other governing
body, officers, employees or any person or entity whose negligence would be
imputed to a Party) from engineering, repair, supervision, inspection,
testing, protection, operation, maintenance, replacement, reconstruction, use
or ownership of the released Party's electrical system, Plant(s) or associated
facilities in connection with the implementation of this Agreement. Except for
any loss, damage, claim, cost, charge or expense resulting from Willful
Action,


                            -14-





    






each Party releases the other Party, its directors or other governing body,
officers and employees from any such liability.
           10.2 For the purpose of this Section 10, Willful Action shall be
defined as action taken or not taken by a Party at the direction of its
directors or other governing body, officers or employees having management or
administrative responsibility affecting its performance under this Agreement,
as follows:
                10.2.1 Action which is knowingly or intentionally taken or not
taken with conscious indifference to the consequences thereof or with intent
that injury or damage would result or would probably result therefrom.
                10.2.2 Action which has been determined by final arbitration
award or final judgment or judicial decree to be a material default under this
Agreement and which occurs or continues beyond the time specified in such
arbitration award or judgment or judicial decree for curing such default or,
if no time to cure is specified therein, occurs or continues thereafter beyond
a reasonable time to cure such default.
                10.2.3 Action which is knowingly or intentionally taken or not
taken with the knowledge that such action taken or not taken is a material
default under this Agreement.
           10.3 Willful Action does not include any act or failure to act
which is merely involuntary, accidental or negligent.
           10.4 The phrase "employees having management or administrative
responsibility," as used in Section 10.2, means the employees of a Party who
are responsible for one or more of


                            -15-





    







the executive functions of planning, organizing, coordinating, directing,
controlling and supervising such Party's performance under this Agreement with
responsibility for results.
           10.5 Subject to the foregoing provisions of this Section 10, each
Party agrees to defend, indemnify and save harmless the other Party, its
officers, agents, or employees against all losses, claims, demands, costs or
expenses for loss of or damage to property, or injury or death of persons,
which directly or indirectly arise out of the indemnifying Party's performance
pursuant to this Agreement; provided, however, that a Party shall be solely
responsible for any such losses, claims, demands, costs or expenses which
result from its sole negligence or Willful Action.
           11.  AUDITING:
           11.1 IID shall make its books, records, and other supporting
information, as requested, available to Producer or to Producer's designated
contracted representatives with a CPA firm, for the purpose of auditing any
charges or accounts to be kept by IID hereunder. All such audits shall be
undertaken at reasonable times and in conformance with generally-accepted
auditing stan dards.
           11.2 If as a result of such audits Producer believes its charges or
accounts should be adjusted, the findings shall be presented to the Authorized
Representatives. If the Authorized Representatives agree that any audit
finding should result in a revision of charges or accounts, such revisions
shall be


                            -16-





    






retroactive to the first billing for such charges and accounts and shall be
made as soon as practical after determination.
           11.3 The amount of any unresolved dispute shall accrue interest at
the rate of one and one-half percent (1-1/2%) per month, or the maximum legal
rate, whichever is less, compounded monthly for any amount of money ultimately
refunded to Producer.
           12. AUTHORIZED REPRESENTATIVES: Within thirty (30) calendar days
after the Completion Date, as defined in Article I of the Funding and
Construction Agreement, each Party shall designate by written notice to the
other Party a representative who is authorized to act on its behalf in the
implementation of this Agreement. Either Party may at any time change the
designation of its Authorized Representative by written notice to the other
Party.
           13. NO DEDICATION OF FACILITIES: Any undertaking by one Party to
the other Party under any provision of this Agreement shall not constitute the

                            EXHIBIT I.A

                DEVELOPMENT AND METHODOLOGY FOR THE
                    TRANSMISSION SERVICE CHARGE

IID's transmission service charge shall be recalculated during the month of
April of each year, using the methodology summarized in this Exhibit. The
recalculated transmission service charge shall be effective on June 1 of the
year of recalculation.

EI.A-1 Plant Investment

     TAI = WP + PA - TR + GP + M&S

where

      TAI =   Total adjusted investment at the time of calculation.
      WP  =   Estimate of weighted Transmission Plant Cost ($40,980,291) as
              December 31, 1983 calculated using the following formula:
      WP  =   (0.7 x OC) + (0.3 x RCN); where
      OC  =   Cumulative original cost of Transmission
                     Plant as shown in IID's accounting records, obtained by
                     summing the actual cost of all yearly additions to
                     Transmission Plant from 1938 to the end of 1983, (i.e.,
                     $20,700,415).
              RCN =  Estimate of the cumulative reproduction cost
                     to build the Transmission Plant items
                     identified in OC in 1983 dollars.  Calculated
                     by summing the escalated cost of each yearly
                     addition to Transmission Plant starting in
                     1938 up to the end of calendar year 1983
                     using the Handy-Whitman Index for Total
                     Transmission Plant for the Pacific Region,
                     (i.e., $88,300,000).
      PA  =   Cumulative sum of additions to Transmission Plant from January
              1, 1984 to the end of the year preceding the year of
              calculation. Thus, if the calculation takes place in 1996, PA is
              sum of Transmission Plant additions at actual cost from January
              1, 1984 to December 31, 1995.
              PA = Sum of [TPA(i) + OA(i)] where TPA(i) =
              Annual additions to Transmission
                      Plant for each year associated with
                     the Transmission Project, as defined
                      in Section 7.05 of the Funding and
                       Construction Agreement. TPA(i) is
                              calculated for each year from Completion Date of
                              Transmission Project to end of year preceding
                              year of calculation.


                            -EIA-1-






    







                      OA(i) = Other annual additions to Transmission
                              Plant by IID each year. OA(i) is calculated for
                              each year from January 1, 1984 to end of year
                              preceding year of calculation.
      TR = Sum of (i) and (ii) where:
      (i)= For facilities placed in service prior to 1984, the cumulative sum
           of the annual Weighted Retirement Costs (WRC) for retirements from
           Transmission Plant from January 1, 1984 to the end of the year
           preceding the year of calculation. Thus, if the calculation takes
           place in 1996, TR is comprised of the sum of annual Transmission
           Plant retirements from January 1, 1984 to December 31, 1995 with
           each year's original cost adjusted to account for the weighted cost
           of retirement.
           where WRC  = Weighted Retirement Cost for transmission
                        retired in a given year.
                  OCI = Original cost of transmission facilities
                        retired in a given year.
           WRC = 70%*OCI + 30%*OCI*RCN/OC
      (ii) = Cumulative sum of original cost of annual
             transmission retirements for facilities placed in
             service after January 1, 1984.
      GP = General plant investment as shown in IID's accounting records, as
           of the year preceding the year of calculation, allocated to
           transmission use by the ratio of total allocated transmission O&M
           cost to the sum of production O&M cost excluding fuel, distribution
           O&M cost, transmission O&M cost, dispatching cost, and customer
           accounting and services costs.
      M&S= Materials and supplies inventory held by IID as of the year
           preceding the year of calculation, allocated to transmission use by
           the ratio of Transmission Plant Original Cost to Total Electric
           Plant original cost as reflected in IID's accounting records for
           the year preceding the year of calculation.

EI.A-2  Annual Cost
      TAC = (1.25 x CRF x TAI) + OM + A&G
      where
      TAC =  Total Annual Cost.
      CRF =  Annual capital recovery factor calculated for a 33- year
             amortization using the average interest rate for the year
             preceding the year of calculation from the "Merrill Lynch 500
             Municipal Bond Index Electric- Retail."
      OM =   Total allocated transmission O&M cost during the year preceding
             the year of calculation, equal to the sum of (i) dispatching
             costs and (ii) transmission O&M cost allocated to transmission
             use by the ratio of


                            -EIA-2-






    







             Transmission Plant original cost (OC) to Total Transmission Plant
             original cost (including the cost of subtransmission plant) as
             shown in IID's accounting records.
      A&G =  Administrative and general cost during the year
             preceding the year of calculation, allocated to
             transmission use by the ratio of total allocated
             transmission cost (OM) to the sum of production O&M
             cost excluding fuel, distribution O&M cost,
             transmission O&M cost, dispatching cost, and customer
             accounting and services cost. Administrative and
             general cost is comprised of Power Department plus
             Joint Department A&G less Customer Account Expense.

EI.A-3  Monthly Transmission Service Charge
      TSC =     TAC
             --------
             12 x APL
      where
      TSC = Monthly transmission service charge, in $/kW.
      APL = Annual peak load during the year preceding the year
            of calculation, expressed in kW, which is equal to the sum of
            IID's service peak load plus all transmission wheeling commitments
            (including all Transmission Service Entitlements).

      IID, in April each year, will calculate monthly fees for scheduling
services related to Alternative Energy Resources and transactions with other
utilities as follows:

      A.   An appropriate number of scheduling units will be
           assigned to every IID resource, Alternative Energy
           Resource, and transaction with other utilities in
           operation during the preceding year.  The number of
           scheduling units assigned to each resource and/or
           transaction will depend upon the total daily number of
           functions and therefore, estimated time required to
           schedule the resource and/or transaction.  This
           estimate will be directly related to the complexity of
           the scheduling service being provided.  Table 1 shows
           how the total scheduling units were determined for the
           IID system.

      B.   The expenses related to dispatching and scheduling
           services will be equal to the sum of the following:

               1.    IID FPC Account 556 for the year preceding the
           year of calculation

               2. A portion of the annual expenses related to the SCADA and
           AGC systems for the year preceding the year of calculation,
           determined by multiplying one half of the levelized debt service
           payments for the systems by the percentage that FPC Account 556 is
           of the total of FPC Accounts 556, 561 and 581. Table 2 shows
           calculations involved with this step.

      C.   The annual scheduling fee per scheduling unit will be
           determined by dividing the expenses related to
           scheduling found in Step B by the total scheduling
           units from Step A.  The per unit fee will then be
           multiplied by the number of scheduling units assigned
           to each resource and/or transaction to develop an
           appropriate annual scheduling fee for that resource
           and/or transaction.  The monthly scheduling fee will
           then be calculated by dividing the annual fee by 12.
           Table 3 shows the calculation.

The revised scheduling fee will be effective on June 1 of the year in which
they are calculated.
