                AMENDMENT TO PURCHASE POWER CONTRACT, AS AMENDED

          THIS AMENDMENT, made this 19th day of October, 1993, by HAWAII
ELECTRIC LIGHT COMPANY, INC., a Hawaii corporation ("Company"), and PUNA
GEOTHERMAL VENTURE, a Hawaii general partnership ("Seller");

                                    RECITALS:

          A. The Company and Thermal Power Company, as seller therein, had
previously entered into that certain Purchase Power Contract For Unscheduled
Energy Made Available From A Qualifying Facility, dated March 24, 1986
("Purchase Power Contract"), which was subsequently approved by the Public
Utilities Commission ("PUC") in its Decision and Order ("D & O") No. 8692,
filed in PUC Docket No. 5525 on March 25, 1986.

          B. The Seller subsequently succeeded to the interest of Thermal Power
Company under the Purchase Power Contract.

          C. The Company and the Seller entered into that certain Firm Capacity
Amendment To Purchase Power Contract Dated March 24, 1986, dated July 28, 1989
("Firm Capacity Amendment"), which was subsequently approved by the PUC in its
D & O No. 10519, filed in PUC Docket No. 6498 on February 14, 1990.

          D. The Seller's geothermal power project located in Kapoho, Hawaii
("Facility") was from its inception a "qualifying facility" ("QF"), under
Subchapter 2 of the "Standards for Small Power Production and Cogeneration,"
Hawaii Administrative Rules, Title 6, Chapter 74 ("PUC Standards").

          E. As a result of a restructuring of the ownership of the Seller and
the Facility in connection with financing for the Facility, the Facility may,
following such restructuring, no longer qualify as a QF under the PUC Standards,
but such restructuring will not otherwise affect or modify the Seller's
capability of performing its obligations under the Purchase Power Contract, as
amended, and/or the rights of the Company thereunder.

          F. The Company and the Seller firmly believe that the rates for
purchase set forth in the Purchase Power Contract, as amended, are fully
consistent with the provisions of H.R.S. Section 269-27.2 and continue to be in
furtherance of the State's policy to encourage the development of the State's

renewable alternate energy resources, including the geothermal resources.

          G. The Company and the Seller further believe that it is in the best
interests of the parties to amend the Purchase Power Contract, as amended, to
(i) provide that the Facility shall be either (i) a QF or (ii) a producer of
electricity generated from nonfossil fuel sources and thus falling within the
meaning of Section 269-27_2, Hawaii Revised Statutes ("nonfossil fuel
producer"), and to advise the PUC of such amendment.

          NOW, THEREFORE, in consideration of the premises, the parties hereby
agree to amend the Purchase Power Contract and the Firm Capacity Amendment as
follows:

          1.   Amendments to the Purchase Power Contract.

          a. The second WHEREAS clause on page 1 of the Purchase Power Contract
is amended by (i) deleting the following portion of that clause:

          "of a cogeneration facility or small power production facility which
          is a qualifying facility under Subchapter 2 of the PUC's Standards for
          Small Power Production and Cogeneration in the State of Hawaii,
          Chapter 74 of Title 6; and"

and (ii) substituting in lieu thereof the following new portion:

          "of a cogeneration facility or small power production facility which
          is (i) a qualifying facility under Subchapter 2 of the PUC's Standards
          for Small Power Production and Cogeneration in the State of Hawaii,
          Chapter 74 of Title 6, or (ii) a producer of electricity generated
          from nonfossil fuel sources and thus falling within the meaning of
          Section 269-27.2, Hawaii Revised Statutes ("nonfossil fuel producer");
          and"

          b. APPENDIX E on page 19 of the Purchase Power Contract is amended by
deleting subparagraph l.(a)(ii) in its entirety and substituting in lieu thereof
the following new subparagraphs l.(a)(ii):

          "(ii) failure of the Seller's facility, upon its completion and
                operation, to be (i) a qualifying facility under Subchapter 2 of
                the PUC's Standards for Small Power

                                       2.

               Production and Cogeneration in the State of Hawaii, Chapter 74 of
               Title 6 in effect as of the date of this Contract, or (ii) a
               nonfossil fuel producer falling within the meaning of Section
               269-27.2, Hawaii Revised Statutes; or"

          c. All other references or requirements in the Purchase Power Contract
to the Facility being a "QF" or "qualifying facility" are similarly amended by
adding to each such reference or requirement the phrase "or nonfossil fuel
producer falling within the meaning of Section 269-27.2, Hawaii Revised
Statutes".

          2. Amendments to the Firm Capacity Amendment.

          a. The sixth (6th) WHEREAS clause on page 1 of the Firm Capacity
Amendment is amended by deleting that WHEREAS clause in its entirety and
substituting in lieu thereof the following new WHEREAS clause:

          "WHEREAS, the Seller's facility will be (i) a qualifying facility
          under Subchapter 2 of the PUC's Standards for Small Power Production
          and Cogeneration in the State of Hawaii, Chapter 74 of Title 6, or
          (ii) a facility which generates electricity from nonfossil fuel
          sources and thus falling within the meaning of Section 269-27.2,
          Hawaii Revised Statutes;"

          b. All other references or requirements in the Firm Capacity Amendment
to the Facility being a "QF" or "qualifying facility" are similarly amended by
adding to each such reference or requirement the phrase "or nonfossil fuel
producer falling within the meaning of Section 269-27.2, Hawaii Revised
Statutes".

          3. Continuing Effect. Except as amended by this instrument, the Power
Purchase Contract, as amended by the Firm Capacity Amendment, remains in
otherwise unmodified and in full force and effect.

          4. Further Action. The Company and the Seller shall take such further
action as may be necessary or desirable to implement the provisions, and advise
the PUC, of this Amendment to Purchase Power Contract, as amended, as
expeditiously as possible.

          5. Counterparts. This instrument may be executed in any number of
counterparts, each of which shall be deemed an

                                       3.

original, and all of which together shall constitute one and the same
instrument.

          6. Effective Date. This Amendment to Purchase Power Contract, as
amended, shall become effective when signed by the Seller and the Company.

          IN WITNESS WHEREOF, the Company and the Seller have executed this
Amendment to Purchase Power Contract, as amended, as of the day and year first
above written.

          WHEREAS, by Amendment to Purchase Power Contract, As Amended ("Second
Amendment") HELCO and PGV amended the Unscheduled Energy Contract and Firm
Capacity Amendment (the Unscheduled Energy Contract as amended by the Firm
Capacity Amendment and the Second Amendment, and as may be amended from time to
time, is referred to as the "Amended PPC").

          WHEREAS, a number of issues arose between the Company and Seller which
they settled in a Settlement Agreement dated March 7, 1995 ("Settlement
Agreement");

          WHEREAS, as part of the Settlement Agreement, the Company and Seller
agreed to amend the Amended PPC as reflected in the terms and conditions herein
and in "APPENDIX D, POWER PURCHASES BY COMPANY (Interim Period)" for the period
(the "Interim Period") starting with the Effective Date (as defined herein)
until the satisfaction by PGV of all of PGV's obligations under the Settlement
Agreement;

          WHEREAS, subsequent to the Interim Period, HELCO and PGV desire to
revise the Amended PPC to reflect the parties' understanding of the Amended PPC
prior to the Interim Period as reflected in the terms and conditions herein and
in "APPENDIX D, POWER PURCHASES BY COMPANY (Subsequent to Interim Period)";

          WHEREAS, the Seller's facility will continue to be throughout the term
of this contract either (1) a qualifying, small power production facility under
Subchapter 2 of the PUC's Standards for Small Power Production and Cogeneration
in the State of Hawaii, Chapter 74 of Title 6 of the State's Administrative

          WHEREAS, the Seller is not, and will continue not to be throughout the

promises herein, the Company and the Seller hereby agree to amend the Amended
PPC as follows:

          1. Interim Period Appendix D. Upon the Effective Date (as defined
herein), "APPENDIX D, POWER PURCHASE BY COMPANY", of the Amended PPC is deleted
in its entirety and replaced with "APPENDIX D, POWER PURCHASE BY COMPANY
(Interim Period)", which is attached hereto as Attachment A and incorporated
herein by reference.

          2. Subsequent Period Appendix D. Upon the satisfaction by PGV of all
of PGV's monetary and energy obligations under the Settlement Agreement,
"APPENDIX D, POWER PURCHASE BY COMPANY (Interim Period)", shall be deleted in

incorporated herein by reference.

          3. Affiliated Interest. The Seller shall not sell or transfer more

transaction that would make the Seller an Affiliated Interest with the Company
as defined by Section 269-19.5, Hawaii Revised Statutes, without first notifying
the Company and receiving appropriate PUC approval, if any is required. If the
PUC (or any other entity which has the authority to do so) finds that the Seller
is an Affiliated Interest with the Company, the Seller shall have 60 days to
take whatever action may be appropriate to render the relationship not to be an
Affiliated Interest. The Company shall have the right to terminate the Amended
PPC, including this Third Amendment and any future amendments, if the PUC

                                       2

prohibits the Company from recovering any payments made to the Seller under this
Amended PPC, as amended herein and from time to time, due to the effect of
Section 269-19.5, Hawaii Revised Statutes, relating to affiliated interests.

          4. Continuing Effect. To the extent not amended by this Third
Amendment, the Amended PPC shall remain in full force and effect.

          5. Further Performance. Each Party hereto shall and does hereby agree
to make, execute, deliver and cooperate with each other, as the case may be, any
and all agreements, instruments, documents, records and/or funds, as the case
may be, whatsoever required, necessary and/or convenient to effect and
consummate this Agreement and to permit performance of all acts required
hereunder.

          6. Counterparts/Facsimile Signatures. This Agreement may be executed
and delivered by the parties hereto in any number of counterparts, each of which
shall be delivered an original or duplicate original, and all of which together
shall constitute one and the same instrument or agreement. Counterparts may be
exchanged by facsimile, which facsimile signatures shall be effective for all
purposes and treated in the same manner as physical signatures. Notwithstanding
the foregoing, the party using facsimile signatures agrees that it will promptly
forward physically signed copies of this Agreement to the other party.

          7. Effective Date. This Third Amendment becomes effective on the
earlier of sixty (60) calendar days from the date first above written or when
the PUC authorizes, by appropriate decision and order satisfactory to the Seller
and the Company, the Company's energy payments to the Seller hereunder to be
included in the Company's Fuel Clause pursuant to Rule 6-60-6, Standards For
Electric and Gas Utility Service, Title 6, Chapter 60, of the Hawaii
Administrative Rules, or in the Company's base rates pursuant to Section
269-16(b), Hawaii Revised Statutes, whichever occurs first ("Effective Date").

          8. Denial Of Application. Notwithstanding anything in this Agreement
to the contrary, in the event that the Commission denies the Company's
application to include energy payments to Seller in either the Company's Fuel
Clause pursuant to Rule 6-60-6, Standards For Electric and Gas Utility Service,
Title 6, Chapter 60, of the Hawaii Administrative Rules, or in the Company's
base rates pursuant to Section 269-16(b), Hawaii Revised Statutes, within sixty
(60) calendar days from the date first above written, then this Third Amendment
shall be null and void and of no further force and effect.

                                       3

          IN WITNESS WHEREOF, the Company and the Seller have executed this
Third Amendment as of the day and year first above written.

          be paid for at the off-peak energy rates set forth in Section A.3. of
          this APPENDIX D. The rate of delivery of such Energy may exceed the
          Allowed Capacity as set forth in APPENDIX A at any given time.

     2.   Energy furnished by Seller to the Company shall be metered by a
          time-of-day meter. The Company shall not pay for any Energy that may
          be delivered by the Seller prior to installation and operation of the

          operation and maintenance) in cents per kilowatthour, calculated in
          accordance with the provisions of the PUC's Standards, on file with

     5.   During each payment period Seller shall be credited at the rate of
          $0.002 per kilovarhour for each kilovarhour furnished by the Seller to
          the Company in excess of .62 x kwh. The kvarh meters shall be adjusted
          to prevent reversal in the event the power factor is leading.

          Legally Enforceable Obligation as follows:

          a.   On-Peak Period. During the 14 hour period from 7:00 a.m. to 9:00
               p.m. each day, the Seller shall be obligated to deliver energy
               under the Company's Dispatch at a rate equal to the Seller's firm
               capacity obligation described in Paragraph 3 of APPENDIX B of
               this Contract.

          b.   Off-Peak Period. During the 10 hour period from midnight to 7:00

          last day of the calendar month in which the firm capacity was
          provided, of 1/12 of the Annual Capacity Payment Rate.

     2.   The Capacity Payment Rate shall be $4,000,000 per year beginning on
          July 1, 1990, or on the Commercial Operation date, whichever occurs
          first; provided that the Seller has satisfied the Acceptance Test

                                       2

                                                                   ATTACHMENT A
                                                                      TO THE
                                                                 THIRD AMENDMENT

          requirement of Paragraph 3(f)(i) of APPENDIX B; and subject to the
          sanction provision of Paragraph D.1. Of APPENDIX D.

     3.   The Company shall not be required to pay any additional capacity
          payment for any additional power supplied by the Seller, either at the
          Company's or the Seller's request.

     4.   A failure by the Seller to provide the required firm capacity to the
          Company shall result in the reduction in the capacity payment due to
          the Seller from the Company in accordance with Paragraph D of APPENDIX
          D of this Contract. The Company shall not have any obligation to pay
          capacity payments to the Seller for periods in excess of twenty-four
          hours in which the Seller is unable to fulfill its obligations under
          the Contract, including but not limited to (i) circumstances which are
          subject to Paragraph 15 of this Contract relating to Force Majeure
          without fault, or (ii) for periods in which the Seller does not
          fulfill its obligations under Paragraph 3 of APPENDIX B of this
          contract due to the Seller's "default," as such term is defined in
          APPENDIX E of this Contract.

     5.   If the Seller does not satisfy its firm capacity obligations as
          described in Paragraph 3 of APPENDIX B and Paragraph C of this
          APPENDIX D of this Contract, it shall pay sanctions as described in
          Paragraph D of this APPENDIX D.

C.   PERFORMANCE STANDARDS

     1.   The Seller acknowledges and agrees that the Seller's generating
          facility is expected to meet the following minimum standards for
          satisfactory day-to-day performance during each contract year: (i) an
          On-peak Availability (excluding the four-week annual maintenance
          period and downtime due to a catastrophic equipment failure) of 95
          percent or better; (ii) not more than 6 Plant Trips per year; and
          (iii) a forced outage rate of 5 percent or less.

     2.   The "On-peak Availability" of the Seller's Facility (in percent) is to
          be computed by adding the total Energy Under Company's Dispatch
          Subject to a legally Enforceable Obligation available from the
          Seller's unit during the contract year, multiplying the total by 100,
          and dividing by the product of 4,718 on-peak

                                       3

                                                                   ATTACHMENT A
                                                                      TO THE
                                                                 THIRD AMENDMENT

          hours per 48 week year (4,732 for leap years) times the firm capacity
          obligation (prorated on a daily basis, if necessary).

     3.   "Catastrophic Equipment Failure" means a sudden, unexpected failure of
          a major piece of equipment which (i) substantially reduces or
          eliminates the capability of the Seller's Facility to produce power,
          (ii) is beyond the reasonable control of the Seller and could not have
          been prevented by the exercise of due diligence by the Seller, and
          (iii) despite the exercise of all reasonable efforts, requires more
          than sixty (60) days to repair.

     4.   "Plant Trip" means the sudden and immediate removal of the Seller's
          Facility from service as a result of an immediate
          mechanical/electrical/hydraulic control system trip or operator
          initiated trip/shutdown which requires the Company to take immediate
          steps to place an unscheduled generator on line to make up for the
          loss of output of the Seller's Facility; provided, however, that a
          Plant Trip shall not include: (i) any such removal which occurs within
          forty-eight (48) hours of the time at which the Seller's Facility is
          restarted following an outage; (ii) trips caused or initiated by the
          Company; or (iii) trips occurring during periods when the Seller has
          continued to furnish capacity to the Company at the request of the
          Company's Production Manager after the Seller has notified the
          Company's Production Manager that the Seller's Facility is likely to
          trip.

     5.   The "Forced Outage Rate" of the Seller's Facility during a contract
          year is to be computed by totaling the average megawatts unavailable
          for service due to forced outages or deratings on an hourly basis,
          multiplying the total by 100, and dividing by the product of 8,760
          hours per year times the weighted average of the Seller's firm
          capacity obligation (prorated on a daily basis, if necessary).

D.   SANCTIONS

     1.   The capacity payment is to be made on the basis of the full
          availability of the Seller's firm capacity obligation. When the
          Seller's full firm capacity obligation is not available, the Seller
          shall pay the Company $0.0339 per on-peak hour for each kilowatt of
          deficiency based on annual capacity payments of $4 million and 4,718
          on-peak hours in a year. During

          the period from July 1, 1990 to December 31, 1990, the sanction
          provided for in this paragraph shall not exceed the capacity payments
          provided for in Section B.2. of this APPENDIX D on a monthly basis.

     2.   For each contract year in which the On-peak Availability of the
          Seller's Facility is less than 95 percent, the Seller will pay $10,000
          to the Company for each full percentage point of the shortfall unless
          the shortfall is due to a catastrophic equipment failure.

     3.   For each Plant Trip in excess of 6 per contract year, the Seller shall
          pay $10,000 to the Company.

     4.   The Company shall have the right to offset any payment due from the
          Seller under this Paragraph against any payments due to the Seller.

     5.   If the Seller does not deliver 12,500 kw of Firm Capacity as provided
          by Paragraph 3 of APPENDIX B, by December 31, 1990, the Seller shall
          pay the Company $0.0339 per on-peak hour for each kilowatt deficiency
          until the Seller satisfies the Acceptance Test provided in Paragraph
          3(f)(i) for 12,500 kw of Firm Capacity; if the Seller does not deliver
          25,000 kw of Firm Capacity as provided by Paragraph 3 of APPENDIX B,
          by March 1, 1991, the Seller shall pay the Company $0.0339 per on-peak
          hour for each kilowatt deficiency until the Seller satisfies the
          Acceptance Test provided in Paragraph 3(f)(i) for 25,000 kw of Firm
          Capacity.

     6.   Each party may exercise whatever legal or equitable remedies may be
          available to enforce the obligations of this Contract in the event of
          a default by the other party.

A.   ENERGY PURCHASES BY THE COMPANY

     1.   Subject to the other provisions of this Contract, including but not
          limited to Sections 6 and 7, the Company shall accept and pay for
          Energy generated by the Seller's Facility and delivered by the Seller
          to the Company at the higher of: (a) the respective on-peak and
          off-peak energy rates set forth in Section A.3. of this APPENDIX D, or
          (b) the Minimum Purchase Rate set forth in Section A.4. of this
          APPENDIX D; provided, however, that the rate of delivery of such
          Energy shall not exceed the Allowed Capacity as set forth in APPENDIX
          A at any given time.

     2.   Energy furnished by Seller to the Company shall be metered by a
          time-of-day meter. The Company shall not pay for any Energy that may
          be delivered by the Seller prior to installation and operation of the
          Company's meters. The on-peak hours shall be those between 7:00 a.m.
          and 9:00 p.m. daily, and the off-peak hours shall be those between
          9:00 p.m. on one day and 7:00 a.m. on the following day.

     3.   The respective on-peak and off-peak energy rates for Energy shall be
          one hundred percent (100%) of the Company's respective on-peak and
          off-peak Avoided Energy Costs (including avoided costs of fuel and
          operation and maintenance) in cents per kilowatthour, calculated in
          accordance with the provisions of the PUC's Standards, on file with
          the PUC and in effect for the month in which such Energy is delivered,
          as adjusted by the Transformer Loss Adjustment Factor that is to be
          determined pursuant to Paragraph 3(f)(ii) of APPENDIX B.

     4.   The Minimum Purchase Rate in this contract shall apply to all
          deliveries of Energy made by Seller to Company during the term of this
          Contract and to all deliveries of Energy under a Legally Enforceable
          Obligation made by Seller to Company.

     5.   During each payment period Seller shall be credited at the rate of
          $0.002 per kilovarhour for each kilovarhour furnished by the Seller to
          the Company in

                                                                   ATTACHMENT B
                                                                      TO THE
                                                                 THIRD AMENDMENT

          excess of .62 x kwh. The kvarh meters shall be adjusted to prevent
          reversal in the event the power factor is leading.

     6.   Company shall accept and pay for Emergency Energy (as defined in
          APPENDIX F) generated by Seller's Facility and made available by
          Seller to Company, as follows: the respective on-peak and off-peak
          energy rates for Emergency Energy shall be three hundred percent
          (300%) of Company's on-peak and off-peak Avoided Energy Costs
          (including avoided costs of fuel and operation and maintenance) in
          cents per kilowatthour, calculated in accordance with the provisions
          of the PUC's Standards, on file with the PUC and in effect for the
          quarter in which such Energy is delivered.

     7.   The Seller shall deliver Energy under Company Dispatch pursuant to a
          Legally Enforceable obligation as follows:

          (a)  On-Peak Period. During the 14 hour period from 7:00 a.m. to 9:00
               p.m. each day, the Seller shall be obligated to deliver energy
               under the Company's Dispatch at a rate equal to the Seller's firm
               capacity obligation described in Paragraph 3 of APPENDIX B of
               this Contract.

          (b)  Off-Peak Period. During the 10 hour period from midnight to 7:00
               a.m. and 9:00 p.m. to midnight each day, the Seller shall be
               obligated to deliver energy under the Company's Dispatch at a
               rate not greater than the Seller's firm capacity obligation
               described in Paragraph 3 of APPENDIX B of this Contract and not
               less than the Minimum Delivery Guarantee.

B.   CAPACITY PURCHASES BY THE COMPANY

     1.   As compensation for providing the firm capacity under Company Dispatch
          as described in Paragraph 3 of APPENDIX B, the Company will pay the
          Seller a capacity payment, payable monthly within 20 days after the
          last day of the calendar month in which the firm capacity was
          provided, of 1/12 of the Annual Capacity Payment Rate.

     2.   The Capacity Payment Rate shall be $4,000,000 per year beginning on
          July 1, 1990, or on the Commercial Operation date, whichever occurs
          first; provided that the Seller has satisfied the Acceptance Test

                                       2

                                                                   ATTACHMENT B
                                                                      TO THE
                                                                 THIRD AMENDMENT

          requirement of Paragraph 3(f)(i) of APPENDIX B; and subject to
          the sanction provision of Paragraph D.1. of APPENDIX D.

     3.   The Company shall not be required to pay any additional capacity
          payment for any additional power supplied by the Seller, either at the
          Company's or the Seller's request.

     4.   A failure by the Seller to provide the required firm capacity to the
          Company shall result in the reduction in the capacity payment due to
          the Seller from the Company in accordance with Paragraph D of APPENDIX
          D of this Contract. The Company shall not have any obligation to pay
          capacity payments to the Seller for periods in excess of twenty-four
          hours in which the Seller is unable to fulfill its obligations under
          the Contract, including but not limited to (i) circumstances which are
          subject to Paragraph 15 of this Contract relating to Force Majeure
          without fault, or (ii) for periods in which the Seller does not
          fulfill its obligations under Paragraph 3 of APPENDIX B of this
          Contract due to the Seller's "default," as such term is defined in
          APPENDIX E of this Contract.

     5.   If the Seller does not satisfy its firm capacity obligations as
          described in Paragraph 3 of APPENDIX B and Paragraph C of this
          APPENDIX D of this Contract, it shall pay sanctions as described in
          Paragraph D of this APPENDIX D.

C.   PERFORMANCE STANDARDS

     1.   The Seller acknowledges and agrees that the Seller's generating
          facility is expected to meet the following minimum standards for
          satisfactory day-to-day performance during each contract year: (i) an
          On-peak facility Availability (excluding the four-week annual
          maintenance period and downtime due to a catastrophic equipment
          failure) of 95 percent or better; (ii) not more than 6 Plant Trips per
          year; and (iii) a forced outage rate of 5 percent or less.

     2.   The "On-peak Availability" of the Seller's Facility (in percent) is to
          be computed by adding the total Energy Under Company's Dispatch
          Subject to a legally Enforceable obligation available from the
          Seller's unit during the contract year, multiplying the total by 100,
          and dividing by the product of 4,718 on-peak

                                       3

                                                                   ATTACHMENT B
                                                                      TO THE
                                                                 THIRD AMENDMENT

          hours per 48 week year (4,732 for leap years) times the firm capacity
          obligation (prorated on a daily basis, if necessary).

     3.   "Catastrophic Equipment Failure" means a sudden, unexpected failure of
          a major piece of equipment which (i) substantially reduces or
          eliminates the capability of the Seller's Facility to produce power,
          (ii) is beyond the reasonable control of the Seller and could not have
          been prevented by the exercise of due diligence by the Seller, and
          (iii) despite the exercise of all reasonable efforts, requires more
          than sixty (60) days to repair.

     4.   "Plant Trip" means the sudden and immediate removal of the Seller's
          Facility from service as a result of an immediate
          mechanical/electrical/hydraulic control system trip or operator
          initiated trip/shutdown which requires the Company to take immediate
          steps to place an unscheduled generator on line to make up for the
          loss of output of the Seller's Facility; provided, however, that a
          Plant Trip shall not include: (i) any such removal which occurs within
          forty-eight (48) hours of the time at which the Seller's Facility is
          restarted following an outage; (ii) trips caused or initiated by the
          Company; or (iii) trips occurring during periods when the Seller has
          continued to furnish capacity to the Company at the request of the
          Company's Production Manager after the Seller has notified the
          Company's Production Manager that the Seller's Facility is likely to
          trip.

     5.   The "Forced Outage Rate" of the Seller's Facility during a contract
          year is to be computed by totaling the average megawatts unavailable
          for service due to forced outages or deratings on an hourly basis,
          multiplying the total by 100, and dividing by the product of 8,760
          hours per year times the weighted average of the Seller's firm
          capacity obligation (prorated on a daily basis, if necessary).

D.   SANCTIONS

     1.   The capacity payment is to be made on the basis of the full
          availability of the Seller's firm capacity obligation. When the
          Seller's full firm capacity obligation is not available, the Seller
          shall pay the Company $0.0339 per on-peak hour for each kilowatt of
          deficiency based on annual capacity payments of $4 million and 4,718
          on-peak hours in a year. During the period from July 1, 1990 to
          December 31, 1990,

                                       4

                                                                      TO THE
                                                                 THIRD AMENDMENT

          the sanction provided for in this paragraph shall not exceed the
          capacity payments provided for in Section B.2. of this APPENDIX D on a
          monthly basis.

     2.   For each contract year in which the On-peak Availability of the
          Seller's Facility is less than 95 percent, the Seller will pay $10,000
          to the Company for each full percentage point of the shortfall unless
          the shortfall is due to a catastrophic equipment failure.

     3.   For each Plant Trip in excess of 6 per contract year, the Seller shall
          pay $10,000 to the Company.

     4.   The Company shall have the right to offset any payment due from the
          Seller under this Paragraph against any payments due to the Seller.

     5.   If the Seller does not deliver 12,500 kw of Firm Capacity as provided
          by Paragraph 3 of APPENDIX B, by December 31, 1990, the Seller shall
          pay the Company $0.0339 per on-peak hour for each kilowatt deficiency
          until the Seller satisfies the Acceptance Test provided in Paragraph
          3(f)(i) for 12,500 kw of Firm Capacity; if the Seller does not deliver
          25,000 kw of Firm Capacity as provided by Paragraph 3 of APPENDIX B,
          by March 1, 1991, the Seller shall pay the Company $0.0339 per on-peak
          hour for each kilowatt deficiency until the Seller satisfies the
          Acceptance Test provided in Paragraph 3(f)(i) for 25,000 kw of Firm
          Capacity.

     6.   Each party may exercise whatever legal or equitable remedies may be
          available to enforce the obligations of this Contract in the event of
          a default by the other party.
