incurred in performing its limited warranty hereunder.

                                   ARTICLE 8

                            SUSPENSION OF SERVICES

     8.1   CPD may suspend all or a part of the services to be performed by COC
under this Agreement by written notice to COC, for any of the following reasons:

           (a)  Force majeure causes as set forth in Paragraph 12.1, or any
other reason that causes shutdown of the Facility or Resource Area for a period
of more than 20 consecutive calendar days or for more than 30 days in any 60 day
period.

           (b)  Inability of the Facility, the Resource Area to properly operate
for any reason including but not limited to unavailability of geothermal
resource in sufficient quality or quantity, malfunction of equipment,
unavailability of materials, equipment, supplies or labor, or structural
defects.

           (c)  SCE's inability or refusal to accept power from the Facility.

           (d)  Navy activities or restrictions which prohibit economical
operation of the Facility or the Resource Area.

                                      11


           (e)  Failure of COC to perform the Required Services, Drilling
Services or Emergency Services in accordance with the standards set forth in
Article 5 of this Agreement.

     8.2   Upon receipt of notice of suspension from CPC, COC shall continue to
perform its non-suspended services under this Agreement at such personnel
staffing and performance levels as are prudently dictated by the circumstances.
COC shall have the right during any such suspension to terminate the employment
of any of its personnel.  Any cost of reemployment for the performance of
services under this Agreement shall be payable as a Direct Cost under Section
4.2.

     8.3   Except in connection with Section 8.1(e), in the event of suspension,
CPD shall continue to pay COC all compensation in accordance with Article 4,
unless it is determined that such suspension will extend for more than 30
calendar days.  In the event such suspension will extend for more than 30
calendar days CPD shall compensate COC for costs associated with winding down
and restarting the operation and maintenance activities to the extent provided
for in the Operating Budget.

     8.4   COC may, by giving 30 days written notice to CPD, suspend all or a
part of its services under this Agreement if CPD shall fail to make any payment
when due as required under Article 4, provided that no such suspension shall
occur if the required payment is made within the notice period and except for
any Operating Fees which are not paid on account of the Subordination Agreement.

                                   ARTICLE 9

                                   INSURANCE

     9.1   COC shall procure and maintain in force the insurances listed below,
which shall contain waivers of subrogation with respect to loss or damage
resulting from COC's performance under this Agreement;

           (a)  Comprehensive general liability coverage, including bodily
injury, physical damage, and automobile liability, in the amount of $5,000,000
combined single limit.

           (b)  California Workers' Compensation coverage in statutory form and
amount.

           (c)  Such additional insurance as may be reasonably required by CPD
from time to time.

     9.2   COC shall provide to CPD such evidence of the required insurance as
CPD may reasonably specify.

                                      12


     9.3   Each of the required policies shall be endorsed to provide that the
party requiring the insurance be given thirty (30) days advance notice of
cancellation or material change.

     9.4   Each of the required insurances shall be primary insurance for all
purposes and shall be so endorsed.

                                  ARTICLE 10

                                  TERMINATION

     10.1  COC may terminate its performance under this Agreement upon six
months' written notice to CPD.  CPD may terminate COC's performance under this
Agreement upon six months' written notice to COC. Should such termination occur,
COC shall be paid for its services to the date of termination in accordance with
Article 4 (including any costs payable under Section 10.3) less any out-of-
pocket costs incurred by CPD in obtaining a replacement operator to perform the
services contemplated by this Agreement.

     10.2  If either party commits a material breach of its obligations under
this Agreement, the other party (hereinafter the "Non-Defaulting Party") may
give such party in default (hereinafter the "Defaulting Party") a written notice
describing such breach in reasonable detail and, if the breach is remediable,
demanding that the Defaulting Party cure it.  If the breach is not remediable,
the Defaulting Party shall be in default under this Article 10.  If the breach
is remediable, and the Defaulting Party does not cure the breach within sixty
(60) days after its receipt of such notice or, if the breach is such that it can
be cured but not within such period of time, does not promptly commence action
which is calculated to cure such breach within a reasonable period of time and
thereafter diligently pursue such action to completion, then the Defaulting
Party shall be deemed to be in default under this Article 10.  Upon a default
under this Article 10:

           (a)  If the Defaulting Party is CPD, then COC shall have the right to
terminate this Agreement by written notice to CPD, without prejudice to any
remedies at law or in equity that are available to COC by reason of CPD's
default.  In addition, the costs reasonably incurred by COC in effecting
termination in accordance with the terms of this provision, including severance
pay and relocation costs for any terminated employees, shall be paid to COC.

           (b)  If the Defaulting Party is COC, then CPD may suspend COC's
Performance under this Agreement and engage a third party to perform the
services COC is obligated to perform under this Agreement until such time as COC
is able to resume performance.  If, within 30 days of such suspension, COC
demonstrates to the reasonable satisfaction of CPD that it is able to perform
fully under this Agreement, and to compensate CPD for all costs, losses or
damages incurred which arise from COC's prior incomplete performance or failure
to perform, then COC shall be reinstated under this Agreement with

                                      13


full powers and rights as it had prior to the suspension. If COC shall not be
reinstated under the Agreement as contemplated in the preceding sentence, then
CPD shall have the right to terminate this Agreement by written notice to COC,
effective immediately upon such notice, without prejudice to any remedies at law
or in equity that are available to CPD by reason of COC's default.

     10.3  If a default is not cured as provided in Section 10.2, the Non-
Defaulting Party may elect to suspend performance hereof on a month-by-month
basis rather than terminate the Agreement.  If the Non-Defaulting Party suspends
performance, the Defaulting Party may remedy such default during the period of
suspension and pay the Non-Defaulting Party its losses or damages, plus interest
at the rate of 10% per annum.  Upon the remedy of such default and payment of
such damages to the Non-Defaulting Party, such default shall cease to exist and
the Non-Defaulting Party may not terminate this Agreement unless the Defaulting
Party commits a separate material breach of this Agreement which permits
termination pursuant to this Article. The remedy provided by this Section 10.3
is in addition to other remedies provided elsewhere in this Agreement.

     10.4  Subject to the applicable provisions of other documents entered into
by the parties, either party may terminate this Agreement by written notice to
the other party if the latter party (a) commences a voluntary proceeding under
any federal or state bankruptcy, insolvency or reorganization law, or (b) has
such a proceeding filed against it and fails to have such proceeding stayed or
vacated within 30 days, or (c) upon the end of any such stay, fails to have such
involuntary proceeding vacated within 30 days thereafter, or (d) admits the
material allegations of any petition in bankruptcy filed against it, or (e) is
adjudged bankrupt, or (f) makes a general assignment for the benefit of its
creditors, or if a receiver is appointed for all or a substantial portion of
such party's assets and is not discharged within 30 days after his appointment.
Any termination of this Agreement pursuant to this Section 10.4 shall be
considered to be by reason of anticipatory breach of contract, and such
termination shall be without prejudice to any rights the terminating party may
have by reason of such anticipatory breach.

     10.5  If SCE terminates the Power Purchase Contract because of an uncured
default of the Power Purchase Contract that was the result of COC's gross
negligence or willful misconduct, then this Agreement shall be terminated
effective upon termination of the Power Purchase Contract.

     10.6  In case of a termination pursuant to this Article 10, CPD and COC
shall arrive at a schedule for a transition period, at the end of which COC
shall be relieved of its obligations under this Agreement.  During the
transition period, COC shall cooperate with any party appointed to be
replacement field operator to ensure a smooth transition of service.  In
addition, COC shall arrange for the transfer to CPD of any permits and licenses
for the Facility or any resource development activities in connection therewith
held in the name of COC.  In case of a termination, COC shall be entitled to the
termination and demobilization payments contemplated

                                      14


by this Article 10, unless the termination results from a default by COC as
defined in this Article 10, in which case no termination or demobilization
payments shall be due to COC under this Agreement.

     10.7  Subject to earlier termination pursuant to the terms of this Article
10, the term of this Agreement shall expire on December 31, 2009.

                                  ARTICLE 11

                                INDEMNIFICATION

     11.1  Each party shall defend, indemnify, and hold harmless the other from
and against all claims, demands, liability, loss, suit, judgment, cost, damage
or expense incurred or suffered by the indemnified party (including the cost of
investigating, analyzing and defending such matters, and including court costs
and reasonable attorneys' fees) relating to, resulting from or arising out of
acts or omissions of the indemnifying party and connected in any way with its
performance under this Agreement, whether or not insured against, except to the
extent caused by the gross negligence of the party otherwise indemnified.  The
indemnity granted herein shall include indemnity for damage to property or to
the environment and for injury to or death of any person, including employees of
COC and CPD.  "Acts or omissions" of a party shall include acts or omissions of
lower tier subcontractors, suppliers, or others operating within the scope of
authorization of such party.

     11.2  Where one party is obligated under this or other Articles to
indemnify another, such obligations shall extend to the partners and affiliates
of the party indemnified, and to directors, officers, agents, and employees of
any of them.

                                  ARTICLE 12

                           MISCELLANEOUS PROVISIONS

     12.1  Any delay or stoppage of work due to any of the following causes
shall constitute a Force Majeure event for such a period as such obligations
cannot be performed: acts of God, fire, flood, earthquake, explosion, riot, war,
sabotage, terrorism, or governmental acts and decrees. However, such delay or
stoppage shall not constitute a Force Majeure event if such event is caused by
the active or passive negligence or the intentional acts or omissions of the
delayed party. The delayed party shall recommence the performance of its
obligations as promptly and expeditiously as possible following any such delay
or stoppage. If any such Force Majeure event continues for 45 days, either party
may terminate this Agreement in accordance with the provisions of Article 10,
including without limitation the provisions regarding payment to COC of
termination and demobilization payments.

                                      15


     12.2  Any controversy between COC and CPD or claim of either COC or CPD
arising out of or related to this Agreement, or the breach thereof, shall first
be referred to the management of COC and management committee of CPD for
resolution.  If agreement cannot be reached, the parties may pursue other means
for resolving the dispute.

     12.3  Any notice, demand or request provided for in this Agreement shall be
