               failed, for a continuous period of thirty (30) minutes, to
               deliver power adjusted per the Correction Curves at a level of at
               least ninety five percent (95%) of the Nominated Capacity. For
               the purpose of defining Outage Hour, if NAPOCOR requests dispatch
               of capacity in excess of the amount defined in Subsection (a) of
               the definition of Outage, failure to deliver such excess amount
               shall not constitute an Outage Hour. For purpose of calculating
               the Total Outage Hours (TOH) for any given period (including
               Billing Period), the following formula shall be used:

                           n 0.95 x NC - (ACi + NRCi)

                TOH = (Sigma) ----------------------------------- x Wi

                      i=l0.95 x NC

where:

TOH    =   Total outage hours in any Billing Period.

NC     =   Nominated Capacity for that Billing Period expressed in kW.

n      =   The number of hours in that Billing Period.

ACi    =   The total power delivered during hour i expressed in kW adjusted
           per the Correction Curves.

                                       6

NRCi   =   NC less power requested by NAPOCOR in hour i, expressed in kW.

wi     =   Variable for hour i defined as follows:

if,

1)  (ACi  +  NRCi)  (greater than or equal to) 0.95 x NC; or

2)  (ACi  +  NRCi)  (less than) 0.95 x NC for a period shorter than 30 continues
                                minutes in hour i;

                         or

3)  Any of the events defined in Subsections (a), (b), (c), (d), (e) and (f) of
    the definition of Outage occurs during hour i,

then   wi = 0

otherwise   wi = 1

          disturb existing structures and facilities on the land so furnished
          for construction purposes unless and until given written permission by
          appropriate authorities. Unreasonable withholding or delay of such
          permission shall constitute Force Majeure.

     (c)  PNOC-EDC shall make available to the Operator, free and clear of liens
          and encumbrances that could interfere with the Operator's construction
          or operation of the Plants and at no cost to the Operator, all other

          and other documents for the importation of the Operator-owned
          construction or maintenance equipment that it may decide to bring into
          the country for use in connection with this Agreement. PNOC-EDC shall
          use its best efforts in assisting the Operator to obtain all such
          licenses and documents.

     (b)  PNOC-EDC shall use its best efforts to cause the Government to grant
          the Operator exemptions from all custom duties or other importation or
          exportation tax in respect of all items of plant, machinery and
          ancillary items, including consumables and spare parts, required for

          Subsection 4.1(a) equivalent to the period of the delay in obtaining
          such permits, licenses and other documents. The Operator or PNOC-EDC
          shall promptly notify the other Party of each such delay, and the
          Parties shall cooperate to promptly satisfy the relevant authority and
          remove the cause of the delay. Any delay in excess of sixty (60) days
          after notification by the Operator to PNOC-EDC shall cause Article 9
          to apply. The Operator shall not be subject to delay penalties as a
          result of such a delay.

4.6  PERMITS

     Following the Effectivity Date, the Operator, at no cost to PNOC-EDC, shall
     be responsible for securing from the Government all requisite

     except the Environmental Compliance Certificate, which shall be obtained by
     PNOC-EDC. PNOC-EDC shall cooperate with and use its best efforts to assist
     the Operator in obtaining such authorization, licenses and permits.

     Any delays, caused by an event of Force Majeure and to the extent that they
     materially affect the Operator's ability to undertake its performance under
     this Agreement, caused in obtaining requisite authorizations, licenses and
     permits shall extend the Completion Date and other benchmark dates day for
     day. The Operator or PNOC-EDC shall promptly notify the other Party of each
     such delay, and the Parties shall cooperate to promptly satisfy the
     relevant Authority and remove the cause of delay. Any delay in excess of
     sixty (60) days after notification shall cause Article 9 to apply. The
     Operator shall not be subject to delay penalties as a result of such a
     delay.

     The Operator shall comply with the following on matters of drawings and
     other documentary information, and PNOC-EDC rights thereto:

     4.7.1 SUBMISSION OF DRAWINGS AND DATA

          The Operator shall submit to PNOC-EDC copies of all drawings, plans,
          calculations, operating and maintenance instructions and, in general,
          copies of all material documents related to the Power Plant reasonably
          requested for reference and information. Prior to the start of
          construction,

                                       18

          within thirty (30) working days following receipt thereof, PNOC-EDC
          shall describe to the Operator in writing any flaws perceived by
          PNOC-EDC in the designs. Failure by PNOC-EDC to describe any flaws in
          such designs within such thirty (30) day period shall be deemed
          PNOC-EDC's waiver of its right to describe such flaws.

          The Operator shall also advise PNOC-EDC of the names of potential
          suppliers of material components or material services who have been
          shortlisted by the Operator. Within thirty (30) working days following
          receipt of such advice, PNOC-EDC shall advise the Operator of any such
          potential suppliers to which PNOC-EDC objects, together with the
          reasons for objection and may request the Operator to exclude such
          suppliers from the shortlist. The Operator shall comply with such
          requests by PNOC-EDC as it shall deem reasonable.

          Following the start of construction by the Operator on the Site, and
          in any case not earlier than 120 days after the Effectivity Date, the
          above-mentioned thirty (30) working days periods shall be reduced to
          fifteen (15) working days.

     4.7.2 MODIFICATION RIGHTS

          During the same thirty (30) or fifteen (15) working day period
          following the receipt of the documents or list of such suppliers under
          Section 4.7.1, PNOC-EDC shall have the right to require modifications
          to the design as it deems necessary within the scope of work set forth
          in Annex B and Annex C for proper and safe operation of the Power
          Plant as it affects the operation of the PNOC-EDC geothermal fluid
          collection and disposal system and the NAPOCOR power system. In the
          event PNOC-EDC requests any Elective Modifications, then the Parties
          shall negotiate in good faith (i) to adjust the Contract Capacity
          Price to maintain the Operator's economic return on its investment as
          if no such Elective Modifications were performed and (ii) adjust the
          dates set forth in Section 4.1 to reflect any delays in designing such
          Elective Modifications and any additional time required by the
          Operator to complete such Elective Modifications; provided that the
          Operator shall not be required to make such Elective Modifications if
          such Elective Modifications would likely impair the Operator's ability
          to perform its obligations hereunder. In the event the Parties are
          unable to reach agreement on such adjustments within sixty (60) days
          following PNOC-EDC's request, PNOC-EDC may withdraw such request.
          Thereafter, if such request is not withdrawn, the Operator shall
          either comply with such request or terminate this

                                       19

          Agreement by giving written notice of termination to the PNOC-EDC;
          provided, however, that if the Operator gives such a written notice of
          termination to PNOC-EDC, PNOC-EDC shall have five (5) working days
          following delivery of such notice of termination to again withdraw its
          request. If such request is withdrawn by PNOC-EDC such written notice
          of termination will be of no effect. Upon such termination, the
          provisions of Article 9 shall apply. If, following the process as
          described in this Subsection 4.7.2, in the Operator's reasonable
          judgment a delay has been caused to its construction schedule, and
          such a delay is not due to a flaw in the Operator's drawings, the
          dates set forth in Subsection 4.1(a) shall be extended and adjusted
          proportionally to such a delay.

     4.7.3 FUTURE MODIFICATION

          All changes to the design of the Power Plant desired by the Operator
          shall be subject to the review and approval of PNOC-EDC and such
          approval shall not be unreasonably withheld. Except as set forth in
          Section 4.7.2 and this section, neither Party shall have the right to
          make or require any changes in the design of the Power Plant without
          the prior written consent of the other Party.

     4.7.4 CONSTRUCTION SCHEDULE

          The Operator shall submit to PNOC-EDC a detailed construction schedule
          of the Power Plant within three (3) months following the Effectivity
          Date. This schedule shall contain, in particular, dates for the
          submission of all drawings, documents and data, acceptance thereof,
          witnessing of tests and the overall procurement schedule. PNOC-EDC
          shall have the right to review and approve, which approval shall not
          be unreasonably withheld, the construction schedule of the Power
          Plant. Failure to disapprove such schedule within thirty (30) days
          following receipt of the same shall be deemed PNOC-EDC's approval of
          the same.

     4.7.5 MONITORING RIGHTS

          PNOC-EDC shall be entitled at its own cost to monitor the progress and
          quality of the construction and installation work. For this purpose,

     the construction work due to any of the following causes:

          (i)    Failure of the Operator to obtain the necessary access to the
                 Site, or failure of PNQC-EDC to deliver and accept geothermal
                 fluid meeting the Geothermal Fluid Specifications; or the
                 failure of PNOC-EDC to fulfill any of its other obligations
                 that at Operator's reasonable judgment will cause a delay in
                 the scheduled Completion Date; or the failure of the Operator,
                 for reasons not attributable to the Operator, to obtain the
                 Authorization to Construct and Permit to Operate; or

          (ii)   Any delay described in Sections 4.5 and 4.6, or any delay
                 caused by a PNOC-EDC directed modification in accordance with
                 Subsection 4.7.2 other than a modification which is
                 necessitated by a flaw in the Operator's drawings or any delays
                 as a resultof requirements upon the Operator by PNOC-EDC or by
                 any relevant Government authority to install an H2S abatement
                 system; or

          (iii)  Delays due to Force Majeure conditions:

     the Operator shall promptly notify PNOC-EDC of such delay, including
     details and supporting documents reasonably calculated to describe the
     problem, steps taken to resolve it and any proposed cooperative solution.
     Any delay under the terms of this

                                       22

     Section 4,10 shall extend day for day, unless otherwise agreed between the
     Parties, the Guaranteed Commercial Operation Date and all other related
     target dates directly related to the delay and within the responsibility of
     Operator.

4.11 PENALTY DUE TO DELAYS

     (a)  In the event the Commercial Operation Date of any individual Plant
          does not occur on or before the relevant Guaranteed Commercial
          Operation Date (as the same may be extended pursuant to this Agreement
          or by mutual agreement), the Operator shall pay PNOC-EDC an amount as
          defined in Annex 13. If the Operator fails to pay such amount within
          five (5) working days after due, PNOC-EDC shall have the right to draw
          on the Construction Performance Security to the extent of the amount
          defined in Annex E. In no event shall the aggregate amount of
          penalties for delay exceed the sum of $5,700,000.

     (b)  In the event that the Commercial Operation Date of any Plant does not
          occur within one hundred fifty (150) calendar days following the
          Guaranteed Commercial Operation Date for that Plant (as the same may
          be extended pursuant to this Agreement or by mutual agreement) then
          Section 15.4.1 shall apply.

4.12 LIGHTS AND BARRIERS

     During construction, the Operator shall put up and maintain at the Site
     such danger lights and barriers as the Operator deems reasonably necessary

     from sunset to sunrise during the performance of such work such adequate
     lighting on or about the Site and on the work area as the Operator deems
     necessary for the safety of the construction forces and for the proper
     observance and inspection of the construction and erection activities.

ARTICLE 5 TESTING OF THE FACILITY

5.1  TESTING PROCEDURES

     The procedures for the testing of the Power Plant set forth in Annex F
     shall be followed by the Operator.

5.2  TEST SCHEDULES

     (a)  The Operator and PNOC-EDC shall agree on test schedules and schedules
          of Geothermal Fluid requirements for the tests for the Power Plants.
          The schedules shall take into consideration the operational
          requirements of PNOC-

                                       23

          EDC and NAPOCOR, provided, however, that the Operator shall not be
          delayed by more than 7 calendar days in his proposed test schedules.

     (b)  In so far as Plants 1,2 and 3 are concerned, the Operator agrees to
          accept Geothermal fluid for a total period of three (3) months during
          the commissioning period. Over these three (3) months the Operator, at
          Operator's request, shall be entitled to two (2) months of Geothermal
          Fluid supply for plant 3 and two (2) months of Geothermal Fluid supply
          for Plants 1 and 2.

5.3  NOTICE OF TESTS

     The Operator shall notify PNOC-EDC at least fifteen (15) calendar days
     prior to carrying out any tests on the Power Plant and prior to:

     (a)  the initial parallel operation of each of the Operator's Plants; and

     (b)  all testing of the Protective Apparatus.

5.4  TESTS BEFORE COMPLETION

     (a)  PNOC-EDC reserves the right to witness all tests, including equipment
          testing at the Operator's or other subcontractor's or equipment
          supplier's premises during the course of this Agreement. NAPOCOR shall
          have the right to have a representative present at all tests of the
          Protective Apparatus.

     (b)  The representatives of PNOC-EDC shall have the right to be present
          during any test activity done by the Operator on the Power Plant.
          Tests conducted without the presence of PNOC-EDC's representative
          shall not be valid for the purposes of this Agreement; provided that
          if the Operator has complied with the notice provisions of Section 5.3
          and PNOC-EDC representative fails to be available for such tests at
          the scheduled time, the Operator may conduct such tests and such tests
          shall be valid for the purpose of this Agreement and the Operator
          shall have the right to issue, without need of PNOC-EDC's concurrence,
          the certificates required by Section 5.4(c).

     (c)  Upon completion of any test, the Operator and PNOC-EDC shall jointly
          issue a certificate that testing has been done on each Plant and that
          agreed testing procedures shown in Annex F had been followed.

     (d)  The Operator shall use best efforts to demonstrate the Power Plant's
          ability to provide to NAPOCOR on behalf of PNOC-EDC the Contracted
          Capacity. If, pursuant to the tests performed pursuant to this Article
          5, any Plant is unable to demonstrate a capacity equal to its
          proportional portion of the Contracted

                                       24

          Capacity, then the Operator shall perform the tests required by this
          Article 5 at such other capacity as the Operator elects. Upon
          completion of such tests, the Parties shall certify the Completion
          Date for the relevant Plant.

     (e)  No later than seven (7) calendar days after the Completion Date of
          each Plant, the Operator shall notify PNOC-EDC of the adjusted
          Nominated Capacity of the Power Plant for the first year of operation.
          The total Nominated Capacity of the Power Plant for the first year of
          operation shall be adjusted upon the Completion Date of each Plant in
          order to include the proportional portion of the Nominated Capacity
          related to that completed Plant.

     (f)  All costs, excluding Geothermal Fluid, incurred during the testing of
          the Power Plant shall be borne by the Operator.

     (g)  Energy generated during testing shall be delivered to NAPOCOR on
          behalf of PNOC-EDC and paid for by PNOC-EDC at fifty percent (50%) of
          the rate actually paid by NAPOCOR to PNOC-EDC. The Operator shall bill
          PNOC-EDC for such energy in accordance with Section 8.4.

     (h)  Notwithstanding anything to the contrary in this Agreement, in the
          event that, from and after the date set forth in Section 4.1 for the
          start of commissioning of a Plant, that Plant is capable of being
          tested, but performance tests required under Section 5.4(d) cannot be
          performed because of:

          (i)    an Interconnection Failure; or

          (ii)   PNOC-EDC's failure to deliver or accept Geothermal Fluid as
                 specified in the Geothermal Fluid Specifications; or

          (iii)  the Operator's failure to receive all permits, licenses, other
                 governmental approvals and utilities required for operation of
                 the Power Plant, notwithstanding its reasonable efforts to
                 obtain the same, and assuming the Operator has complied with
                 the scope of work set forth in Annex B; or

          (iv)   PNOC-EDC or NAPOCOR's failure to provide any personnel or
                 resource necessary to witness and approve such testing; or

          (v)    any dispute between PNOC-EDC and NAPOCOR (under the Power
                 Purchase Agreement or otherwise) which did not arise from any
                 default of the Operator under this Agreement, including the
                 termination or expiration of the Power Purchase Agreement,
                 then, in any such events, the Completion Date for such Plant(s)
                 shall be deemed to have occurred and

                                       25

                 PNOC-EDC shall be obligated to commence payments of the
                 Capacity Payments and the Energy Fee to the Operator on and
                 from the Completion Date provided, however, that Completion
                 Date for such payments shall not occur prior to August 1, 1997.
                 The capacity for purposes of calculating the Capacity Payments
                 payable under this Subsection shall be deemed to be delivery of
                 Nominated Capacity equal to the Contracted Capacity of such
                 Plant(s).

     At such time when all events described in subparagraphs (i), (ii), (iii),
     (iv) and (v), above have been cured and no longer exist regarding the
     affected Plant, the Operator shall perform the performance tests required
     under Section 5.4(d) and advise PNOC-EDC of the adjusted Nominated Capacity
     of the Power Plant and thereafter shall receive Capacity Payments based on
     the adjusted Nominated Capacity.

     In the event that the Operator is unable to pass all of the Plant's
     performance tests as set forth herein and provided that such tests are
     conducted within six (6) months from the Completion date of the affected
     Plant, the Operator will be obligated to refund or credit against future
     capacity made available and actually delivered to PNOC-EDC that amount of
     Capacity Payment actually received by the Operator prior to and during such
     tests which exceeds the amount of Capacity Payment which the Operator would
     have been paid at the lower capacity rating actually demonstrated in
     testing the Plant.

     In the event there is a difference of opinion about test results before or
     during the Cooperation Period, which cannot be resolved by the Parties
     within seven (7) days, the controversy shall be resolved by a reputable
     engineering firm chosen in advance as provided herein after. The Operator
     shall propose the engineering firm, acceptable to PNOC-EDC which acceptance
     shall not be unreasonably withheld, and the Parties will agree on such
     engineering firm not later than six (6) months prior to the estimated start
     of the Commissioning Period for the first Plant. The Parties shall equally
     share any costs associated with this procedure.

5.5  TESTS DURING COOPERATION PERIOD

     The net plant capacity and the Net Plant Steam Rate shall be tested every
     year in the presence of PNOC-EDC personnel following the procedures set
     forth in Annex F. This test shall be performed at the Operator's election
     within six (6) months after completion of the annual maintenance on each
     individual Plant and shall form the basis for determining the Nominated
     Capacity for the following year under Section 6.13. The Operator shall be
     entitled to repeat any of the aforesaid tests. If any of the events
     described in Subsection 5.4(h) affect the results of any such tests, the
     provisions of Subsection 5.4(h) shall apply for purposes of determining
     Nominated Capacity for such year.

                                       26

     (a)  Upon the substantial completion of the Power Plant and subject to
          confirmation by PNOC-EDC (which confirmation shall not be unreasonably
          withheld), the Operator may certify that the Completion Date of the
          Power Plant has occurred notwithstanding that the Power Plant is
          unable to produce the Contracted Capacity adjusted per the Correction
          Curves or to achieve the Guaranteed Net Plant Steam Rate, but in that
          event adjustments shall be made to the Capacity Payments in accordance
          with the penalty provisions of Subsection 8.3.1; provided, however,
          that such certification may not be made if the Power Plant is unable
          to produce at least seventy percent (70%) of the Contracted Capacity,
          after application of the Correction Curves.

     (b)  On the Completion Date of the Power Plant, the Operator shall commence
          the delivery of electric capacity and energy to NAPOCOR on behalf of
          PNOC-EDC and shall be paid for such delivery in accordance with the
          provisions of Section 8.3. All other related provisions on the
          operation of the Power Plant and the tariffs, discounts, bonuses, and
          penalties on the regular sale of electric capacity and energy shall
          also take effect on this date.

6.2  POWER RATES FOR INITIAL DELIVERY

     In the event that the Completion Date of any Plant falls on a date other
     than the Commercial Operation Date, PNOC-EDC shall pay the Contract
     Capacity Price for the Power Plant to the Operator on a prorated basis
     based on the number of days elapsed from the Completion Date.

6.3  DEDICATION OF FACILITY

     The Operator shall operate and dedicate all energy and capacity of the
     Power Plant (net of Operator's and PNOC-EDC's usage allowed hereunder) to
     NAPOCOR.

          provided in accordance with a program to be agreed between PNOC-EDC
          and the Operator and shall be provided at no cost to PNOC-EDC.

     (b)  PNOC-EDC shall endeavor to offer to the Operator that PNOC-EDC take
          over the employment of such of the Operator's operating and
          maintenance staff employed on the Power Plant at the end of the
          Cooperation Period as PNOC-EDC may, at its sole discretion, consider
          suitable for employment with PNOC-EDC and under such terms and
          conditions of employment as PNOC-EDC shall consider acceptable.

13.4 CONDITION OF POWER PLANT ON TRANSFER

     (a)  Within a period of six (6) months prior to the Transfer Date, the
          Operator shall undertake performance and efficiency testing of the
          Power Plant as specified in Annex F to demonstrate the condition of
          the Power Plant at the Transfer Date.

     (b)  Notwithstanding any testing performed pursuant to Section 13.4(a), the
          Power Plant and all other equipment transferred pursuant to this
          Agreement shall be transferred on an "as is" basis and any warranties
          which would otherwise be

                                       47

          inherent defects, description or otherwise of whatsoever nature will
          be excluded; provided, however, that upon transfer the Operator shall
          warrant that, on the Transfer Date, the Power Plant will be free from
          all liens and encumbrances created by the Operator. After the Transfer
          Date, the Operator shall be under no liability whatsoever to PNOC-EDC
          the respect of the operation or otherwise of the Power Plant by
          PNOC-EDC or a person designated by PNOC-EDC and PNOC-EDC shall
          indemnify and keep indemnified the Operator against any liability to
          any person or damage to any property arising from the use or operation
          of the Power Plant after the Transfer Date, provided, however, that

          Party may, after such period, either (a) suspend this Agreement by
          giving written notice of suspension to the other Party or (b) upon
          thirty (30) days written notice, terminate this Agreement and the
          provisions of Article 9 shall apply. Except that in case of such delay

          party has the right to initiate a consultation between the Parties, to
          take place during such thirty (30) day notice period, in order to try
          and agree on conditions for eventual waiving of the recourse to the
          provisions of Article 9 and provided that if an agreement can not be

          day period specified in the second sentence of Section 9.1.

ARTICLE 15 SUSPENSION, TERMINATION AND ABANDONMENT

15.1 TERMINATION PRIOR TO EFFECTIVITY DATE

     (a)  Each Party shall use good-faith efforts to cause the conditions set
          forth in Article 26 to be satisfied as promptly as practicable after
          the date of this Agreement and

                                       50

          each Party will exercise reasonable discretion in electing to
          terminate this Agreement pursuant to this Section 15.1.

     (b)  If the Effectivity Date has not occurred by March 1, 1996, or within
          such longer period as the Parties may agree to, due to a failure of
          the conditions set forth in Section 26.1 to have been satisfied prior
          to such date, if such conditions have not been waived in writing by
          PNOC-EDC, the Parties shall consult with each other in good faith with
          the view to achieving the Effectivity Date. If a mutually acceptable
          arrangement is not reached and implemented within fifteen (15) days
          thereafter, either Party shall have the right to terminate this
          Agreement by giving written notice to the other Party. Upon such
          termination, PNOC-EDC shall return to the Operator all security held
          by PNOC-EDC in connection with this Agreement, including any bid
          securities, letters of credit and bank guarantees, the Operator shall
          reimburse PNOC-EDC for all costs and expenses incurred by PNOC-EDC as
          of the date of and in connection with this Agreement except those of
          PNOC-EDC related to the preparation of the request for proposals and
          the bid evaluation until such termination, and thereafter, neither
          Party shall have any further liability to the other and this Agreement
          shall immediately and automatically become null and void.
          Notwithstanding anything to the contrary in this Agreement, this
          provision shall become effective upon execution of this Agreement and
          shall remain effective until the Effectivity Date.

     (c)  If the Effectivity Date has not occurred by March 1, 1996, or within
          such longer period as the Parties may agree to, due to a failure of
          the conditions set forth in Section 26.2 to have been satisfied prior
          to such date, if such conditions have not been waived in writing by
          the Operator, the Parties shall consult with each other in good faith
          with the view to achieving the Effectivity Date. If a mutually
          acceptable arrangement is not reached and implemented within fifteen
          (15) days thereafter, either Party shall have the right to terminate
          this Agreement by giving written notice to the other Party. Upon such
          termination, PNOC-EDC shall return to the Operator all security held
          by PNOC-EDC in connection with this Agreement, including any bid
          securities, letters of credit and bank guarantees, PNOC-EDC shall
          reimburse the Operator for all costs and expenses incurred by the
          Operator as of the date of and in connection with this Agreement, and
          thereafter, neither Party shall have any further liability to the
          other and this Agreement shall immediately and automatically become
          null and void. Notwithstanding anything to the contrary in this
          Agreement, this provision shall become effective upon execution of
          this Agreement and shall remain effective until the Effectivity Date.

     (d)  If the Effectivity Date has not occurred by March 1, 1996, or within
          such longer period as the Parties may agree to, due to a failure of
          the conditions set forth in

                                       51

          Section 26.3 to have been satisfied prior to such date, if such
          conditions have not been waived in writing by both Parties, the
          Parties shall consult with each other in good faith with the view to
          achieving the Effectivity Date. If a mutually acceptable arrangement
          is not reached and implemented within fifteen (15) days thereafter,
          each Party shall bear its own costs and expenses. In the event,
          however, of the failure of the condition in Section 26.3 (a) (ii)
          other than for reasons due to adverse economic or political conditions
          in the Philippines, and the Parties do not waive the fulfillment of
          this condition, either Party may terminate this Agreement by giving
          written notice to the other Party, and the Operator shall reimburse
          PNOC-EDC for all costs and expenses incurred by PNOC-EDC as of the
          date of and in connection with this Agreement except those of PNOC-EDC
          related to the preparation of the request for proposals and the bid
          evaluation until such termination. Neither Party shall have any
          further liability to the other and this Agreement shall immediately
          and automatically become null and void. Notwithstanding anything to
          the contrary in this Agreement, this provision shall become effective
          upon execution of this Agreement and shall remain effective until the
          Effectivity Date.

     (e)  Costs and expenses referred to in this Section 15.1 shall not include
          any consequential or special damages (including without limitation
          lost profits, lost revenues, increased operating costs or loss of
          revenues from the Power Plant), whether such liability arises in
          contract, warranty, tort (including negligence) or otherwise.

     (f)  The amount of costs and expenses to be reimbursed by either Party to
          the other Party under this Section 15.1 shall be estimated by an
          independent accountant jointly appointed by the Parties and the costs
          associated with such estimation shall be paid by the Party making the
          reimbursement.

15.2 TERMINATION FOR DEFAULT AND SUSPENSION OF DELIVERY

     (a)  PNOC-EDC may temporarily suspend receipt of electricity from the
          Operator for:

          (i)    Tampering with meters by the Operator; or

          (ii)   A condition on the Operator's side of the Point of
                 Interconnection, dangerous to life or property.

                 Such condition shall be subject to confirmation by an
                 independent third party expert satisfactory to both Parties. If
                 so confirmed, PNOC-EDC shall be excused payment of capacity and
                 energy charges for the duration

                                       52

                 of such suspension and such suspension shall cease on
                 rectification of the initiating condition.

     (b)  Subject to the Operator's cure rights set forth in paragraph (c)
          below, upon the material breach by the Operator of any of its
          obligations hereunder, PNOC-EDC may, as its sole remedy, terminate
          this Agreement. Upon such termination, (i) if termination occurs prior
          to the Commercial Operation Date, the entire proceeds of the
          Construction Performance Security shall be forfeited in favor of
          PNOC-EDC and the Operator shall transfer, at no cost, all of the
          Operators right, title and interest in the Power Plants to PNOC-EDC
          and (ii) if termination occurs after the Commercial Operation Date of
          the Power Plant, the Operator shall transfer, at no cost all of the
          Operator's right, title and interest in the Power Plants to PNOC-EDC.
          Upon such termination and forfeiture and/or transfer, as the case may
          be, the Operator shall have no further liability hereunder.

     (c)  No such termination shall be made by PNOC-EDC without thirty (30) days
          (or longer pursuant to this paragraph) prior written notice to the
          Operator. Such notice shall be delivered, personally or by registered
          mail, stating in particular the provision of this Agreement which has
          been violated. If the Operator fails to correct any default within the
          thirty (30) day period from its receipt of the notice, or such period
          exceeding thirty (30) days as reasonably necessary to accomplish such
          cure provided the Operator has commenced curing such default within
          such thirty (30) day period and continues to diligently proceed to
          cure such default until cured, PNOC-EDC may terminate this Agreement;
          provided, however, that any dispute by the Operator in good faith as
          to the correctness of any bill from PNOC-EDC shall not be a cause to
          terminate this Agreement. Any suspension of the deliveries of
          electricity to NAPOCOR on behalf of PNOC-EDC or termination of this
          Agreement upon any authorized grounds shall in no way relieve the
          Operator of its liability to compensate PNOC-EDC for any amounts owed
          by the Operator to PNOC-EDC under this Agreement less any amounts owed
          by PNOC-EDC to Operator under this Agreement.

15.3 SUSPENSION OF PAYMENT

     Subject to the provisions of Section 14, payments under this Agreement,
     upon written request of the Operator, and for a period reasonably required
     to replace or repair the Power Plant, may be suspended if the Operator is
     temporarily unable to produce the electric capacity or energy contracted
     for due to physical destruction of or damage to the Power Plant.

                                       53

15.4 ABANDONMENT

     15.4.1 ABANDONMENT DURING CONSTRUCTION

     The construction of any or all of the Plants shall be deemed abandoned to
     the extent set forth below under any of the following circumstances:

     (a)  If the Operator, through a written notice to PNOC-EDC, terminates
          construction of the Plants other than by reason of Force Majeure or
          for reasons not attributable to the Operator with the intent that such
          termination be permanent;

     (b)  If the Operator fails (other than by reason of Force Majeure or for
          reasons not attributable to the Operator) to place a confirmed order
          for the long lead items in turbo-generators) within one hundred twenty
          (120) days period following the Effectivity Date;

     (c)  If the Operator fails (other than by reason of Force Majeure or for
          reasons not attributable to the Operator) to resume work (i) within
          one hundred twenty (120) calendar days following receipt of insurance
          proceeds relating to, and in amounts sufficient to cover loss or
          damage arising from, a Force Majeure situation affecting one or more
          of the Plants provided, however, that in case of release to the
          Operator of partial insurance proceeds, the Operator shall resume work
          to the extent of the amounts so collected, or (ii) in case no material
          damage to such Plants has occurred, within one hundred twenty (120)
          calendar days following the termination or cessation of such Force
          Majeure situation, provided that a notice of such termination or
          cessation was given by PNOC-EDC to the Operator; or

     (d)  Subject to the provisions of Section 14 and except for reasons not
          attributable to the Operator, if the Commercial Operation Date of any
          Plant does not occur within one hundred fifty (150) calendar days
          following the relevant Guaranteed Commercial Operations Date (as the
          same may be adjusted in accordance with this Agreement or by mutual
          agreement).

     If construction of one or more Plants is deemed abandoned as set forth
     above, PNOC-EDC may terminate this Agreement by giving the Operator not
     less than fifteen (15) days prior written notice of its intention to so
     terminate this Agreement. If the Operator has not commenced work under
     clause (b) or (c), as the case may be, of this Section 15.4.1 before the
     expiration of such fifteen (15) day period, this Agreement shall
     immediately and automatically terminate. Upon such termination, the
     Operator shall forfeit the portion of the Construction Performance Security
     relating to such abandoned Plants to PNOC-EDC and transfer, upon payment by
     PNOC-EDC of a purchase price calculated pursuant to Section 9.2 for the
     Plants not so abandoned, all of the Operator's right, title

                                       54

     and interest in the Power Plant to PNOC-EDC. Upon such termination,
     forfeiture and transfer, the Operator shall have no further liability
     hereunder.

     15.4.2 ABANDONMENT DURING COOPERATION PERIOD

     The Power Plant shall be deemed abandoned during the Cooperation Period
     under the following circumstances:

     (a)  If the Operator, through a written notice to PNOC-EDC terminates
          operation of the Power Plant with the intent that the termination be
          permanent except for (i) Force Majeure or (ii) reasons not
          attributable to the Operator;

     (b)  If the Operator fails to deliver energy to NAPOCOR on behalf of
          PNOC-EDC for a period of one hundred twenty (120) consecutive calendar
          days other than as a result of an Outage, without written notice of
          temporary suspension, except for (i) Force Majeure or (ii) reasons not
          attributable to the Operator; or

     (c)  Subject to the provisions of Section 14 and except for reasons not
          attributable to the Operator, if within one hundred twenty (120)
          calendar days following receipt of insurance proceeds relating to, and
          in an amount sufficient to cover loss or damage arising from, a Force
          Majeure situation, the Operator fails to resume reconstruction of the
          damaged Plants provided, however, that in case of release to the
          Operator of partial insurance proceeds, the Operator shall resume work
          to the extent of the amounts so collected, or, in case no material
          damage to the Plants has occurred; within one hundred twenty (120)
          days following the termination or cessation of a Force Majeure
          situation, the Operator fails to resume delivery of energy to NAPOCOR
          on behalf of PNOC-EDC, provided that a notice of such termination or
          cessation shall have been given by PNOC-EDC to the Operator.

     If the Plants are deemed abandoned during the Cooperation Period as set
     forth above, PNOC-EDC may terminate this Agreement by giving the Operator
     not less than fifteen (15) days prior written notice of its intention to so
     terminate this Agreement. If the Operator has not commenced work under
     clause (b) or (c), as the case may be, of this Section 15.4.2 before the
     expiration of such fifteen (15) day period, this Agreement shall
     immediately and automatically terminate. Upon such termination, the
     Operator shall transfer, at no cost to PNOC-EDC, all of the Operator's
     right, title and interest in the Power Plant to PNOC-EDC. Upon such
     termination and transfer, the Operator shall have no further liability
     hereunder.

     or the address to which such notices and communications are to be sent.

ARTICLE 18 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.

ARTICLE 19 ASSIGNMENT

     (a)  Except as set forth in paragraphs (b) or (c) below, the Operator shall
          not assign or transfer any or all of its rights and obligations under
          this Agreement without the written consent of PNOC-EDC. Any such
          assignment or

                                       57

          transfer made without such written consent shall be null and void.
          Consent for such assignment or transfer shall not be unreasonably
          withheld, provided that, in the opinion of PNOC-EDC, the assignee or
          transferee possesses all the legal, financial and technical
          qualifications required to operate and maintain the Power Plant.

     (b)  Notwithstanding the foregoing, the Operator may assign or create a
          security interest over its rights and interests in this Agreement for
          the purpose of financing the design, construction, ownership and
          operation of the Power Plant. PNOC-EDC agrees to execute such consents
          to or acknowledgements of such assignments as the Operator or its
          lenders reasonably require and under such terms and conditions
          acceptable to PNOC-EDC. In addition, PNOC-EDC agrees to reasonably
          cooperate with the Operator's proposed lenders and agrees to amend
          this Agreement as reasonably required by such lenders provided such
          amendments do not materially increase PNOC-EDC's obligations or
          materially decrease PNOC-EDC's rights hereunder.

     (c)  All obligations under this Agreement which the Operator agrees to be
          responsible for hereunder shall be assumed by NEWCO which shall
          undertake to perform the Operator's obligations to perform such work
          and in consideration of which shall be paid all fees payable to the
          Operator under this Agreement. NEWCO, in carrying out such work and
          receiving the fees payable to the Operator under this Agreement, shall
          act on its own behalf and for its own benefit, and not as an agent or
          representative of the Operator. For such purpose, PNOC-EDC, the
          Operator and NEWCO shall execute and deliver the Accession
          Undertaking, upon the effectiveness of which NEWCO shall become a
          party hereto without the need of any further action on the part of the
          Operator and the rights and obligations of PNOC-EDC and the Operator
          under this Agreement shall be transferred and amended in accordance
          with the terms of the Accession Undertaking, as fully as if NEWCO had
          executed this Agreement as amended by the terms of the Accession
          Undertaking.

     (d)  Without limiting the generality of Subsection 19(b), PNOC-EDC shall in
          the consent of PNOC-EDC specified in the Subsection 19(b) acknowledge
          and agree that (i) it has been informed of and consents to the
          execution, delivery and performance of the assignment and security
          agreements between the Operator and the lenders, and the terms thereof
          including any provisions relating to the assignment and application of
          the proceeds of insurance policies described in the Agreement and (ii)
          to give the lenders notice of any default under or breach by the
          Operator of any provision of this Agreement or the Accession
          Undertaking and of any abandonment under Article 15 of this Agreement
          and agree to not terminate this Agreement or the Accession Undertaking
          on the basis of such breach, default or abandonment without providing
          the lenders designated in such consent with at least ninety (90) days
          within which to cure such breach, default or abandonment,

                                       58

          which period will commence on the later of (x) the lenders' receipt of
          the aforesaid notice and (y) expiration of the period provided in this
          Agreement for the cure of such breach, default or abandonment by the
          Operator.

ARTICLE 20 PRIVATIZATION ASSURANCES

     In the event that either of the common stock or other equity interests in
     PNOC-EDC, or NAPOCOR, or any other portion of their assets or business
     activities are sold or otherwise transferred or announced to be sold or
     otherwise transferred, or any merger or other corporate reorganization (or
     a series of any of the above):

          (i)    results in a real or purported assignment of rights or
                 assumption of obligation under this Agreement; or

          (ii)   substantially and adversely changes the net assets, projected
                 profits, projected net cash flow from operations, or otherwise
                 would prompt a reasonable person to conclude that the ability
                 if the relevant entity to duly perform its obligations
                 hereunder on timely basis had been materially and adversely
                 affected;

     then the Operator shall have the right to request reasonable assurances
     from PNOC-EDC, NAPOCOR and the Government that the Operator's rights and
     net economic returns under this Agreement are preserved and that PNOC-EDC's
     ability to fully and satisfactorily comply with its obligations under this
     Agreement is not impaired. If no mutually agreed, written resolution of the
     issues is reached within ninety (90) days, then the provisions of Article 9
     shall apply. Without limiting PNOC-EDC's obligation to make such buyout if
     the ability of PNOC-EDC to fund any resulting buyout is in question,
     PNOC-EDC shall exercise any rights it may have to cause NAPOCOR or other
     third-party to assume PNOC-EDC's rights and obligations under this
     Agreement, paying the proceeds directly to the Operator.

ARTICLE 21 DISPUTE RESOLUTION; JURISDICTION

     (a)  As much as possible, all disputes shall be settled amicably between
          the Parties. The Parties each hereby elect binding arbitration as
          their sole and exclusive remedy for any claim arising under this
          Agreement or in any way related to the Project.

     (b)  The Parties agree that in the event that there is any dispute or
          difference between them arising out of this Agreement or in the
          interpretation of any of the provisions hereof, they shall endeavor to
          meet together in an effort to resolve such dispute by discussion
          between them. But failing such resolution, the Chief executives of

                                       59

          PNOC-EDC and the Operator shall meet to resolve such dispute or
          difference, and the joint decision of such Chief Executives shall be
          binding upon the parties hereto. In the event that a settlement of any
          such dispute or difference is not reached pursuant to this subclause,
          then arbitration under the next following subclause shall apply.

     (c)  Where any dispute is not resolved as provided for in the preceding
          subclause, then the Parties shall enter into binding arbitration
          procedures under the rules of conciliation and arbitration of the
          International Chamber of Commerce. Such arbitration shall take place
          in Paris, France before a tribunal of three arbitrators, one to be
          chosen by each of the Operator and PNOC-EDC, and the third to be
          chosen by the two first selected. The arbitration proceedings shall be
          conducted in the English language.

     (d)  To the extent that in any jurisdiction of (i) PNOC-EDC may claim for
          itself or its assets or revenues immunity from suit, execution,
          attachment or other legal process or (ii) there may be attributed to
          PNOC-EDC or its assets or revenues such immunity (whether or not
          claimed), PNOC-EDC agrees not to claim and unconditionally and
          irrevocably waives such immunity to the full extent permitted by the
          laws of such jurisdiction. PNOC-EDC consents generally in respect of
          the enforcement of any judgment against it in any such proceedings in
          any jurisdiction to the giving of any relief or the issue of any
          process in connection with such proceedings (including, without
          limitation, the making, enforcement or execution against any property
          of PNOC-EDC).

ARTICLE 22 ENTIRE AGREEMENT AND SEPARABILITY

     This Agreement constitutes the entire agreement between the Parties hereto
     and supersedes all prior negotiations and agreements, whether written or
     oral. If any part or parts of this Agreement shall be declared invalid by
     competent courts, the other parts hereof shall not thereby be affected or
     impaired.

ARTICLE 23 GOVERNING LAW

     This Agreement shall be governed and construed in accordance with
     Philippine Law.

                                       60

     consequential or special damages (including without limitation lost
     profits, lost revenue, increased operating costs or loss revenues from the
     Power Plant), whether such liability arises in contract, warranty, tort
     (including negligence) or otherwise. Further, except as expressly set forth
     in this Agreement, the Operator make no warranties or guarantees, express
     or implied, with regard to the Power Plant and PNOC-EDC hereby waives any

           FIRST AMENDMENT TO LEYTE OPTIMIZATION PROJECT BOT AGREEMENT

     THIS FIRST AMENDMENT to LEYTE OPTIMIZATION PROJECT BOT AGREEMENT (this
"Amendment") is made as of February 29, 1996, between PNOC-ENERGY DEVELOPMENT
CORPORATION, a wholly owned subsidiary of the Philippine National Oil Company,
organized and existing under Philippine law ("PNOC-EDC") and ORMAT LEYTE CO.
LTD. a Philippine limited partnership ("Operator").

     A. PNOC-EDC and ORMAT INC. a Delaware Corporation executed that certain
Leyte Optimization Project BOT Agreement dated August 4, 1995 which has been
assigned to the Operator (the "Original Agreement"), concerning the development
and operation of a 49 MW (net) geothermal power production facilities in Leyte
Province, the Philippines. All capitalized terms not defined herein shall have
the meanings given them in the Original Agreement.

     B. PNOC-EDC and Operator each acknowledge that some but not all of the
conditions to "Effectivity" of the Original Agreement set forth in Sections
26.1, 26.2 and 26.3 of the Original Agreement have been fulfilled.

     C. PNOC-EDC and Operator recognize that additional time is needed in order
to fulfill the remaining conditions to Effectivity set forth in Sections 26.1,
26.2 and 26.3 of the Original Agreement.

     D. Section 15.1 of the Original Agreement provides, inter alia, that if by
the Effectivity Date of March 1, 1996, one or more of the conditions set forth
in Sections 26.1, 26.2 and 26.3 have not been fulfilled or waived by PNOC-EDC or
the Operator, as the case may be, the parties shall consult in good faith with a
view to achieving Effectivity. Furthermore, Section 3.1(a) states that if the
Effectivity Date does not occur on or before March 01, 1996, the parties shall
discuss and agree on any further extension of the Bid Security.

     E. PNOC-EDC and Operator wish to amend the Original Agreement and the Bid
Security as more fully set forth in this Amendment.

     NOW THEREFORE, the parties hereto, intending to be legally bound, and to
bind their successors and assigns, agree as follows:

     1. Amendment of Section 3.1(a) of the Original Agreement.

     Section 3.1(a) of the Original Agreement is hereby amended to read in its
entirety as follows:

     (a) To guarantee the faithful performance by the Operator of its obligation
to completely construct the Power Plant in accordance with the terms and
conditions of this Agreement, within ten (10) days of the Effectivity Date the
Operator shall post and deliver the Construction Performance Security in a form
acceptable to PNOC-EDC in a sum equivalent to One Hundred Dollars (US $100) per
kilowatt (kW) of total Contracted Capacity for all the Plants or its equivalent
in Philippine Pesos or other currencies. Prior to such delivery, the Operator
shall ensure that the Bid Security required under the bid documents shall be
extended until such time the Construction Performance Security shall have been
posted and delivered; provided that, in the event that the Effectivity Date does
not occur on or before April 10, 1996, the parties shall discuss and agree on
any further extension of the Bid Security. PNOC-EDC shall have recourse to the
Construction Performance Security to satisfy the final judgment in an arbitral
proceeding in accordance with Article 21.

entirety as follows:

     (b) If the Effectivity Date has not occurred by April 10, 1996, or within
such longer period as the parties may agree to, due to a failure of the
conditions set forth in Section 26.1 to have been satisfied prior to such date,
if such conditions have not been waived in writing by PNOC-EDC, the parties
shall consult with each other in good faith with the view to achieving the
Effectivity Date. If a mutually acceptable arrangement is not reached and
implemented within fifteen (15) days thereafter, either party shall have the
right to terminate this Agreement by giving written notice to the other party.
Upon such termination, PNOC-EDC shall return to the Operator all security held
by PNOC-EDC in connection with this Agreement, including any bid securities,
letters of credit and bank guarantees, the Operator shall reimburse PNOC-EDC for
all costs and expenses incurred by PNOC-EDC as of the date of and in connection
with this Agreement except those of PNOC-EDC related to the preparation of the
request for proposals and the bid evaluation until such termination, and
thereafter, neither party shall have any further liability to the other and this
Agreement shall immediately and automatically become null and void.
Notwithstanding anything to the contrary in this Agreement, this provision shall
become effective upon execution of this Agreement and shall remain effective
until the Effectivity Date.

     4. Amendment of Section 15.1(c) of the Original Agreement

     (c) If the Effectivity Date has not occurred by April 10, 1996, or within
such longer period as the parties may agree to, due to a failure of the
conditions set forth in Section 26.2 to have been satisfied prior to such date,
if such conditions have not been waived in writing by the Operator, the parties
shall consult each other in good faith with the view to achieving the
Effectivity Date. If a mutually acceptable arrangement is not reached and
implemented within fifteen (15) days thereafter, either party shall have the

                                       3

Upon such termination, PNOC-EDC shall return to the Operator all security held
by PNOC-EDC in connection with this Agreement, including any bid securities,
letters of credit and bank guarantees, PNOC-EDC shall reimburse the Operator for
all costs and expenses incurred by the Operator as of the date of and in
connection with this Agreement, and thereafter, neither party shall have any
further liability to the other and this Agreement shall immediately and

this Agreement, this provision shall become effective upon execution of this
Agreement and shall remain effective until the Effectivity Date.

     5. Amendment of Section 15.1(d) of the Original Agreement

     (d) If the Effectivity Date has not occurred by April 10, 1996, or within
such longer period as the parties may agree to, due to a failure of the
conditions set forth in Section 26.3 to have been satisfied prior to such date,
if such conditions have not been waived in writing by both parties, the parties
shall consult each other in good faith with the view to achieving the
Effectivity Date. If a mutually acceptable arrangement is not reached and
implemented within fifteen (15) days thereafter, either party shall bear its own
costs and expenses. In the event, however, of the failure of the condition in
Section 26.3(a)(ii) other than for reasons due to adverse economic or political
conditions in the Philippines, and the parties do not waive the fulfillment of
this condition, either party may terminate this Agreement by giving written
notice to the other party, and the Operator shall reimburse PNOC-EDC as of the
date of and in connection with this Agreement except those of PNOC-EDC related
to the preparation of the request for proposals and the bid evaluation until
such termination. Neither party shall have any further liability to the other
and this Agreement shall immediately and automatically became null and void.
