April 16, 1985, between Second Imperial Geothermal Company and Southern
California Edison Company.

     5.2 The Transmission Service Entitlement to be provided by IID for the
Plant shall be contingent on a Plant Connection Agreement being in effect.
Transmission service for the Plant shall commence on the Date of Initial Service
of such Plant. Producer's Authorized Representative shall give IID's Authorized
Representative written notice of the Date of Initial Service at least thirty
(30) days before the Date of Initial Service.

6. TRANSMISSION SERVICE:

     6.1 Subject to the terms of this Agreement, IID shall provide to Producer
and Producer shall purchase from IID transmission service over IID's
transmission system for the Plant. IID shall make arrangements with Edison to
provide, at Producer's or Edison's expense, for the transfer of the electrical
power to be delivered to Edison hereunder from IID's transmission system to
Edison's transmission system at the Point(s) of Delivery.

     6.2 The Transmission Service Entitlement for the Plant shall be the Maximum
Transmission Service Entitlement for such Plant specified in Exhibit II or any
subsequent Plant Amendments, or such lesser amount as may be established as
follows. Beginning on the Date of Initial Service for the 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 Producers' Authorized Representative give IID's Authorized Representative
a ninety (90) day advance written notice as to the adjustment

                                       4

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 2-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
2-year period.

     6.3 The Transmission Service Entitlement selected by Producer for the 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
II or any subsequent Plant Amendments, provided, however, that the following
shall apply to the 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
II 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

                                       5

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 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.

                                       6

     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:

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

          The transmission service for each Plant affected shall be curtailed by
multiplying the Transmission Service Entitlement in accordance with Exhibit II
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 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.

                                       7

     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.

     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 II and in any subsequent Plant Amendments.

                                       8

     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 II 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. 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. My 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. The initial rate is specified in Exhibit I-A 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

                                       9

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.

     8.3 An initial monthly scheduling fee, as specified in Exhibit II 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. 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 & Accounting

                               All billings by IID shall be sent to

                                       10

                               Second Imperial Geothermal Company
                               343 Second Street, Suite N
                               Los Altos, CA 94022

     9.2 Either Party's Authorized Representative may at any time, by advance
written notice to the other Party's 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 dispute 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
data 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 concur pursuant to Section
6.5.1 or Section 6.5.2 exceed a cumulative total of twenty-four (24) hours
during any calendar month based on 730 hours per month representing the full
transmission service charge. The amount of such pro rata reduction

                                       11

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 expanse 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,

responsibility," as used in Section 10.2, means the employees of a Party who are
responsible for one or more of 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 16, 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.

                                       13

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
representative(s) 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 standards.

     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
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 dedication of the
system or any portion thereof by the Party to the public or to the other Party,
and it is understood and agreed

                                       14

that any such undertaking under any provision of this Agreement by a Party shall
cease upon the termination of its obligations hereunder.

14. NON-WAIVER: None of the provisions of this Agreement shall be considered
waived by either Party except when such waiver is given in writing. The failure
of either Party to insist in any one or more instances upon strict performance
of any of the provisions of this Agreement or to take advantage of any of its
rights hereunder shall not be construed as a waiver of any such provisions or
the relinquishment of any such rights for the future; but the same shall
continue and remain in full force and effect.

15. NO THIRD PARTY RIGHTS: The Parties do not intend to create rights in or to
grant remedies to any Third Party or others as a beneficiary of this Agreement
or of any duty, covenant, obligation or undertaking established hereunder.

16. UNCONTROLLABLE FORCES: Neither Party shall be considered to be in default in
the performance of any of its obligations under this Agreement when a failure of
performance shall be due to an uncontrollable force. The term "uncontrollable
force" shall mean any cause beyond the control of the Party affected including,
but not restricted to, failure of or threat of failure of facilities which have
been maintained in accordance with generally-accepted engineering and operating
practices in the electrical utility industry, flood, drought, earthquake,
tornado, storm, fire, pestilence, lightning and other natural catastrophes,
epidemic, war, riot, civil disturbance or disobedience, strike, labor dispute,
labor or material shortage, sabotage, government priorities and restraint by
court order or public authority (whether valid or invalid) and actions or
nonaction by or inability to obtain or keep the necessary authorizations or
approvals from any governmental agency or authority, the failure or inability of
Edison to receive the electric power to be transmitted hereunder at the Point(s)
of Delivery, which by exercise of due diligence such

                                       15

Party could not reasonably have been expected to avoid and which by exercise of
due diligence it has been unable to overcome. Nothing contained herein shall be
construed as to require a Party to settle any strike or labor dispute in which
it may be involved. Either Party rendered unable to fulfill any of its
obligations under this Agreement by reason of an uncontrollable force shall give
prompt written notice of such fact to the other Party and shall exercise due
diligence to remove such inability with all reasonable dispatch.

17. ASSIGNMENTS:

     17.1 Any assignment by Producer of its interest in this Agreement which is
made without the written consent of IID (which shall not be unreasonably
withheld) shall not relieve Producer from its primary liability for any of its
duties and obligations hereunder, and in the event of any such assignment
Producer shall continue to remain primarily liable for payment of any and all
money due IID hereunder and for the performance and observance of all other
covenants, duties and obligations to be performed and observed hereunder by it
to the same extent as though no assignment has been made.

     17.2 Notwithstanding any provision of Section 17.1 to the contrary, prior
to the end of the Credit Installment Period, as defined in Article I of the
Funding and Construction Agreement, Producer's right to transmission service
under this Agreement with respect to the Plant may be assigned only (i) to a
purchaser or co-owner of such Plant or to a person who will operate such plants
pursuant to a contract or other arrangement with such purchaser and in either
case only with the prior written consent of IID (which shall not be unreasonably
withheld) or (ii) for security purposes, to a bank or other entity which
provides financing for such Plant or any electrical transmission facilities
associated therewith. Producer and IID agree that nothing in this Section 17.2
may be amended, modified or waived without the prior written consent of each and

                                       16

every party to the Funding and Construction Agreement (except for any parties in
default thereunder).

     17.3 Whenever an assignment of Producer's interest in this Agreement is
made with the written consent of IID, Producer's assignee shall expressly assume
in writing the duties and obligations hereunder of Producer and, within thirty
(30) days after any such assignment and assumption of duties and obligations,
Producer shall furnish or cause to be furnished to IID a true and correct copy
of such assignment and assumption of duties and obligations.

     17.4 Subject to the foregoing restrictions on assignments, all of the terms
of this Agreement shall be binding upon and inure to the benefit of both of the
Parties and their respective successors, permitted assigns and legal
representatives.

18. GOVERNING LAW: This Agreement shall be interpreted, governed by and
construed under the laws of the State of California or the laws of the United
States, as applicable.

19. NOTICES: Any notice, demand or request provided for in this Agreement, or
served, given or made in connection with it, shall be in writing and shall be
deemed properly served, given or made if delivered in person or sent by United
States mail, postage prepaid, to the persons specified below unless otherwise

                  METHODOLOGY AND CALCULATION OF SCHEDULING FEE

                              ANNUAL DETERMINATION

                                       OF

                               IID SCHEDULING FEES

During the month of April each year, Imperial Irrigation District (IID) 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 preceeding 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 service 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 preceeding 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.

when such curtailment, interruption or reduction is required in order for IID to
construct, install, maintain, repair, replace, remove, investigate or inspect
any of its equipment or any part of its system of if IID determines that such
curtailment, interruption or reduction is necessary because of a System
Emergency, forces outages or abnormal operating conditions on its system. IID
shall use reasonable efforts to

keep interruptions and curtailments to a minimum time.

16. LIABILITY

         16.1 Neither Party shall hold the other Party, its officers, agents or
employees liable for any loss, damage, claim, cost, or expense for loss of or
damage to property, or injury or death of persons, which arises out of the first
Party's ownership, operation or maintenance of facilities on its own side of the
Point of Delivery, except as provided in Section 16.2.

         16.2 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 or breach of or default under 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
misconduct.

17. UNCONTROLLABLE FORCE

         Neither Party shall be considered to be in default with respect to any
obligation hereunder, other than the obligations to pay money, if prevented from
fulfilling such obligation by reason of an uncontrollable force. The term
"uncontrollable force" means any cause beyond the control of the Party affected,
including, but not limited to, failure or threat of imminent failure of
facilities, flood, earthquake, storm, lighting, fire, epidemic, war, riot, civil
disturbance, sabotage and restraint by court or public authority, which by
exercise of due diligence and foresight could not reasonably have been avoided.
Whichever Party is rendered unable to fulfill any obligation by reason of
uncontrollable forces shall give prompt written notice of such fact to the other
Party and shall exercise due diligence to remove such inability with all
reasonable dispatch. Nothing in this Agreement shall require a Party to settle
any strike or labor dispute in which it is involved.

officer of each Party.

19. NON-WAIVER

         None of the provisions of this Agreement shall be considered waived by
either Party except when such waiver is given in writing. The failure of either
Party to insist in any one or more instances upon strict performance of any of
the provisions of this Agreement or to take advantage of any of its rights
hereunder shall not be construed as a waiver of any such provisions or the
relinquishment of any such rights for the future; but the same shall continue
and remain in full force and effect.

20. NO DEDICATION OF FACILITIES

         Any undertaking by one Party to the other Party under any provision of
this Agreement shall not constitute the dedication of the system or any portion

24. ARBITRATION

         24.1 Any dispute arising out of or relating to this Agreement, or the
breach thereof, which is not resolved by the Parties acting through their
Authorized Representatives shall be settled by arbitration to the extent
permitted by the laws applicable to the Parties; provided, however, that no
Party to the dispute shall be bound to any greater extent than any other Party
to the dispute. Arbitration shall not apply to any dispute or mater that is
within the jurisdiction of any regulatory agency.

         24.2 Any demand for arbitration shall be made by written notice to the
other Party setting forth in adequate detail the nature of the dispute, the
issues to be arbitrated, the amount or amounts, if any, involved in the dispute,
and the remedy sought. Within twenty (20) days from the receipt of such notice,
the other Party may submit its own written statement of the dispute and may set
forth in adequate detail any additional related matters or issues to be
arbitrated.

         24.3 Within thirty (30) days after delivery of the written notice
demanding arbitration, the Parties acting through their Authorized
Representatives shall meet for the purpose of selecting an arbitrator. The
Parties may agree upon a single arbitrator, but in the event that they cannot
agree, three arbitrators shall be used. Each Party shall designate one
arbitrator, and the two

arbitrators shall then select a third arbitrator. All arbitrators shall be
persons skilled and experienced in the field in which the dispute has arisen and
no person shall be eligible for appointment as an arbitrator who is or has been
an officer or employee of either of the Parties or otherwise interested in the
matter to be arbitrated. Should either party refuse or neglect to appoint an
arbitrator or to furnish the arbitrators with any papers or information
demanded, the arbitrators are empowered, by both Parties, to proceed without the
participation or assistance of that Party.

         24.4 Except as otherwise provided in this Section, the arbitration
shall be governed by the rules and practices of the American Arbitration
Association, or a similar organization if the American Arbitration Association
should not at the time exist.

         24.5 Arbitration proceedings shall be held in Imperial, California, at
a time and place to be selected by the arbitrators. The arbitrators shall hear
evidence submitted by the Parties and may call for additional information which
shall be furnished by the Party having such information. The arbitrators shall
have no authority to call for information not related to the issues included in
the dispute or to determine other issues not in dispute.

         24.6 If there is only one arbitrator, his decision shall be binding and
conclusive on the Parties. If there are three arbitrators, the decision of any
two shall be binding and conclusive. The decision of the arbitrators shall
contain findings regarding the issues involved in the dispute, including the
merits of the positions of the Parties, the materiality of any default, and the
remedy or relief to which a Party shall be entitled. The arbitrators may not
grant any remedy or relief which is inconsistent with this Agreement, nor shall
the arbitrators make findings or decide issues not in dispute.

         24.7 The fees and expenses of the arbitrators shall be shared equally
by the Parties, unless the decision of the arbitrators specifies some other
apportionment. All other expenses and costs of the arbitration shall be borne by
the Party incurring such expenses and costs.

         24.8 Any decision or award granted by the arbitrators shall be final
and judgement may be entered on it in any court of competent jurisdiction. This
agreement to arbitrate shall be specifically enforceable

25, ENTIRE AGREEMENT

         25.1 The complete agreement of the Parties is set forth in this
Agreement and all communications regarding subject interconnected operations
whether oral or written, are hereby abrogated and withdrawn.

         25.2 IID shall not amend the IID-Edison Transmission Service Agreement
for Alternate Resources between IID and SCE of September 10, 1985 to the extent
that any such amendment shall apply to the Plant without the prior written
consent of ORMESA.

         25.3 Notwithstanding any other provision of the Agreement, if IID has
or hereinafter enters into any plant connection agreement with any alternate
resource developer, which agreement contains terms more favorable to that
developer than the terms extended to ORMESA, IID shall, within thirty (30) days
following execution of such an agreement, modify this Agreement content with
those more favorable terms.
