Change in the Work shall be either a lump-sum fixed price or the recoverable
time and materials price plus overhead and profit in the amount of 10% of such
time and materials price. Company shall respond in writing to any request or
submission by Contractor regarding a Change in the Work within ten (10) Days
following Company's receipt thereof. A Change Order shall be entered into by the
Parties in order for the Change in the Work to be effective. If no agreement can
be reached, the provisions of Section 14 shall be invoked to resolve the
dispute.

      8.2.4   Except to the extent a Change in the Work specifically amends one
or more provisions hereof, all provisions of this Contract shall apply to all
Changes in the Work, and no Change in the Work shall be implied as a result of
any other Change in the Work.

      8.2.5   Contractor shall maintain, in accordance with generally accepted
accounting principles, records and books of account with respect to any Changes
in the Work or other Work involving additional costs in excess of the Contract
Price to be paid by Company on a recoverable cost or time and materials basis.
Company and its authorized representatives shall be entitled to inspect and
audit such records and books of account, during normal business hours and upon
reasonable advance notice.

      8.3     CHANGES CAUSED BY FORCE MAJEURE, CHANGE OF LAW, OR UNCONTROLLABLE
              COMPANY DEFAULT

      8.3.1   Contractor shall give notice to Company of any event of Force
Majeure, Uncontrollable Company Default, or Change of Law affecting Contractor
for which Contractor requires a schedule or price adjustment, which notice
shall, to the extent practicable, include the length of delay, if any, in the
Schedule, and increase in Contractor costs incurred by reason of such event, by
reason of such event and any proposed increase in the Contract Price by virtue
of such event, and Contractor shall substantiate the same to the reasonable
satisfaction of Company.

      8.3.2   Subject to Section 20.2, Company shall (if it accepts the
findings set forth in Contractor's notice issued pursuant to the foregoing and,
with respect to any notice which will have a material effect on the Contract
Price or Schedule, the Independent Engineer), within fifteen (15) Days following
receipt of the notice that specifies the length of the delay, and the proposed
adjustment to the Contract Price, if any, occasioned by such event, issue a
Change Order adjusting the Schedule by extending the time for performance of
Contractor's obligations under this Contract for a period equal to the delay in
completion of the Facility resulting from such event, and increasing the
Contract Price, to the extent Company agrees with the need for such a Change
Order. In the event Company or the Independent Engineer does not accept
Contractor's findings, the propriety of a Change Order for such event shall be
submitted for dispute resolution under Sections 14 and 24.3.

                                     PAGE 21

      8.3.3   Contractor shall use reasonable efforts to remove or mitigate the
effects of any event of Force Majeure, Uncontrollable Company Default, or Change
of Law and to minimize the delay caused thereby, but shall not, without the
prior written approval of Company as set forth in a Change Order issued with
respect thereto, be required to (a) subcontract additional Work or work
additional hours for which premium time is payable, (b) schedule additional work
shifts, or (c) otherwise incur additional costs, if, in any such case, such
subcontracting, additional hours, additional shifts or other additional costs
would not have been required to meet the Guaranteed Completion Date as defined
in the Schedule in effect prior to the occurrence of such event of Force
Majeure, Uncontrollable Company Default, or Change of Law.

      8.3.4   In the event of any emergency affecting the safety or protection
of persons or property or the Work, Contractor, at its discretion and without
any special instruction or authorization from Company, may take all reasonable
actions to prevent threatened damage, injury or loss. Any claim by Contractor
that such emergency constitutes a Change in the Work shall subsequently be
determined by the Parties in accordance with the provisions of this Section 8.

      8.4     EFFECT OF CHANGES ON WARRANTIES AND SAFETY

      8.4.1   If Contractor reasonably believes that a Change in the Work
proposed by Company may negatively affect any warranty or performance
commitments with regard to any Work, Contractor shall serve Company and either
Collateral Agent or the Independent Engineer with written notice within fourteen
(14) Days of Contractor's receipt of such proposal of its reasonable belief and
the believed effect. If Company insists, despite Contractor's notice, to require
the execution of such proposal and Contractor acquiesces to Company's request
and executes the proposal, the affected warranties or performance commitments
will be adjusted to the extent agreed between the Parties or as already
determined in accordance with the provisions of Section 14, but only to the
extent related to or derived from Company's proposal.

      8.4.2   If Contractor reasonably believes that a Change in the Work
proposed by Company may negatively affect safety of the Work or persons under
its supervision or for persons in the vicinity would violate any applicable
Laws, Contractor shall serve Company and either Collateral Agent or the
Independent Engineer with written notice within fourteen (14) Days of
Contractor's receipt of such Company's proposal of Contractor's reasonable
belief and the believed effect. If Company insists, despite Contractor's notice,
to require the execution of such proposal, Contractor shall not be required to
perform such proposal unless determined otherwise under resolution of the
dispute in accordance with Sections 14 and 24.3.

its intended use;

                     (ii)   be free from defects in material and workmanship;
and

                     (iii)  meet the requirements of the Specifications and this
Contract;

              (e)    title and ownership to the Work shall pass to and vest in
Company, as described in Section 12.1, free and clear of any and all liens,
claims, charges, security interests, encumbrances and rights of other persons
arising as a result of any actions or failure to act of Contractor, its

      The warranty period for the warranties set forth in Section 10.1 for an
item of Work (the "WARRANTY PERIOD") shall extend for a period of twelve (12)
Months from the Final Acceptance Date. The Warranty Period with respect to any
item of the Work that is repaired, replaced, modified, or otherwise altered by
Contractor pursuant to Section 10.3 below shall be extended to the longer of:

      (a)     twelve (12) Months from the date of completion of such repair,
replacement, modification or alteration; or

      (b)     the end of the original Warranty Period for the subject item of
the Work;

provided, however, that the Warranty Period shall in no event exceed twenty-four
(24) Months from commencement of the original Warranty Period for the subject
item of the Work.

      10.3    CORRECTION OF IMPROPER WORK

      10.3.1  Company shall notify Contractor promptly upon discovery of any
Defect. In order to be effective hereunder, such notice must be given at the

"failure report," which includes available technical and logistic information to
assist Contractor to assess the damage to the equipment and to evaluate
appropriate corrective action, shall be provided to Contractor as soon as
reasonably practicable upon discovery of the Defect.-- If Contractor requests,
Company shall supply all relevant information relating to past maintenance,
repair and operational data relating to the failed Work.

                                     PAGE 24

      10.3.2  Contractor's responsibility for any such warranty claim shall be

provided by Company or Company's operator without charge, at Contractor's
request.

      10.3.3  All costs associated with the performance of any repair and
maintenance work which is not Defect Remedy Work, including the costs of the

but which are replaced in conjunction with Defect Remedy Work at the request of
Company, shall be the responsibility of Company. Company shall provide
Contractor with access to the Facility and to utilities, tools and equipment
available at the Site for Contractor's performance of any Defect Remedy Work. If
Contractor requests Company to perform such Defect Remedy Work under this
Section 10 instead of Contractor, Company may, at its option, either agree to
cause the Defect Remedy Work to be effected and, in such case, Contractor shall
reimburse Company the costs Company has reasonably incurred as a result; or
Company may insist that Contractor perform or cause the performance of such
Defect Remedy Work.

      10.3.4  The warranty and the liabilities and obligations of Contractor
under this Contract shall not extend to replacement of normal consumables or
apply to any failure to comply with the warranty that has been caused by (i) any
erosion or derosion or normal wear and tear in operation of the subject Work;
(ii) any failure of Company which is an Uncontrollable Company Default or any
failure of a third party, other than Company's operator, Contractor or
Subcontractor, to properly store, install, operate and/or maintain the subject
Work in accordance with good industry practices and the Operation and
Maintenance Manual; (iii) any modifications made to the subject Work by any
person other than personnel of Contractor or Subcontractor without Contractor's

with the Warranty Claim Procedures in Exhibit E.

      10.5    DISCLAIMER AND RELEASE

      THE WARRANTIES, CONDITIONS, OBLIGATION AND LIABILITIES OF CONTRACTOR AND
RIGHTS AND REMEDIES OF COMPANY SET FORTH IN THIS CONTRACT ARE EXCLUSIVE AND IN
SUBSTITUTION FOR, AND COMPANY HEREBY WAIVES, RELEASES AND RENOUNCES, ALL OTHER
PRESENT AND FUTURE WARRANTIES, CONDITIONS, OBLIGATIONS, REPRESENTATIONS AND
LIABILITIES OF CONTRACTOR, TOGETHER WITH ALL OTHER RIGHTS, CLAIMS AND REMEDIES
OF COMPANY AGAINST CONTRACTOR, EXPRESS OR IMPLIED, ARISING BY LAW OR OTHERWISE,
INCLUDING, BUT NOT LIMITED TO, (A) ANY IMPLIED WARRANTY OR CONDITION OF
MERCHANTABILITY OR FITNESS FOR ANY PARTICULAR PURPOSE; (B) ANY IMPLIED WARRANTY
OR CONDITION ARISING FROM COURSE OF PERFORMANCE, COURSE OF DEALING OR USAGE OF
TRADE; (C) ANY OBLIGATION,

                                     PAGE 25

LIABILITY, RIGHT, CLAIM OR REMEDY IN TORT, WHETHER OR NOT ARISING FROM THE
NEGLIGENCE OF CONTRACTOR OR ITS SUBCONTRACTORS, ACTUAL, PASSIVE OR IMPUTED; OR
(D) ANY OBLIGATION, LIABILITY, RIGHT, CLAIM OR REMEDY FOR LOSS OF OR DAMAGE TO
THE FACILITY, WORK OR ANY PORTION THEREOF OR FOR ANY INCIDENTAL OR CONSEQUENTIAL
DAMAGES.

SECTION 11 - REMEDIES

      11.1    LIQUIDATED DAMAGES FOR DELAY IN FINAL ACCEPTANCE

      11.1.1  If the Final Acceptance Date does not occur by the Guaranteed
Completion Date (as the same may be extended in accordance with the terms of
this Contract), Contractor shall pay to Company as liquidated damages, for each
Day which shall elapse between the Guaranteed Completion Date and the Final
Acceptance Date, a sum equal to two-tenth percent (0.2%) of the Contract Price
per week (and/or the pro-rata part of two-tenth percent (0.2%) of the Contract
Price per each period of time which is less than a week, as the case may be);
provided, however, that if the Facility does not achieve Final Acceptance by the
Guaranteed Completion Date, but the Facility nevertheless is generating
electricity, then the liquidated damages payable by Contractor under this
Section 11.1.1 shall be reduced (but not to less than zero) by the amount of the
revenue to which Company is entitled during the period starting on the date
Company is entitled to receive such revenue until the date Final Acceptance
occurs.

      11.1.2  If at any time after the Guaranteed Completion Date, Contractor
is delayed in carrying out the Work as a result of any event identified in
Section 8.1 or Section 20 which would have entitled Contractor to an extension
of time had it occurred prior to the Guaranteed Completion Date, Contractor's
obligation to pay liquidated damages under Section 11.1.1 shall be suspended for
such period as represents the extension of time to which Contractor would have
been entitled had Section 8.1 applied.

      11.1.3  Notwithstanding anything to the contrary herein, liquidated
damages as provided in this Section 11.1 shall be not payable if failure to
achieve Final Acceptance by the Guaranteed Completion Date is due to Force
Majeure or Uncontrollable Company Default.

      11.2    LIQUIDATED DAMAGES FOR FAILURE TO MEET PERFORMANCE GUARANTEE

      11.2.1  In the event that, upon completion of the Performance Test, the
Performance Test result is less than the Performance Guarantee, Contractor shall
have the option for the period specified in Section 6.6.2 to undertake any
necessary actions to increase the output of the Facility to satisfy the
Performance Guarantee at its own cost. If, upon the expiration of such period,
the results of the last Performance Test are below such Performance Guarantee,
then Contractor shall, within thirty (30) Days, pay to Company one payment, as
liquidated damages, of an amount equal to one and one-tenths percent (1.1%) of
the Contract Price for each percentage point (1%) that the final Performance
Test results (as defined in Exhibit D) are below the Performance Guarantee.

      11.2.2  Notwithstanding anything to the contrary herein, liquidated
damages as provided in this Section 11.2 shall not be payable if failure to
achieve the Performance Guarantee is due to Force Majeure or Uncontrollable
Company Default.

      11.3    EXCLUSIVITY

      The liquidated damages payable under this Contract shall, without
duplication, be the sole and exclusive remedy and measure of damages with
respect to any delay in completion of the Facility or any failure to meet the
Performance Guarantee. Once payment of such liquidated damages and other amounts
has been made, or the limits set forth in Section 11.4 below have been met, and
Contractor has

                                     PAGE 26

performed all other Work required hereunder with respect to the Facility,
Contractor shall be relieved of any further Liability with respect to such
failure.

      11.4    GENERAL LIMITATION OF LIABILITY

      11.4.1  Notwithstanding any other provision to this Contract,
Contractor's maximum aggregate Liability under this Contract (including, without
limitation, for liquidated damages) from any and all causes shall in no case
exceed the lower of one hundred percent (100%) of the Contract Price (as the
same may be adjusted in accordance with this Contract) or one hundred percent
(100%) of the amount of the actual payments for the Work received by Contractor
hereunder.

      11.4.2  Except to the extent of the liquidated damages provided for in
this Section 11, in no event shall either Party be liable to the other for any
indirect, special, incidental, consequential or exemplary damages (which
includes loss of profit, revenues or savings), or for costs of procurement of
substitute goods whether arising in contract, equity, tort, or other basis for
Liability, even if it has been advised of the possibility of such damages.

      11.4.3  The foregoing limitations on Liability in this Section 11.4
shall:

              (a)    not limit Company's right to receive proceeds of
Contractor's insurance required to be maintained pursuant to Section 13 of this
Contract;

              (b)    not apply to limit, nor shall they include, the costs of
Contractor's or Company's indemnification obligations under Section 15; or

              (c)    exclude any Liability of Contractor or Company stemming
from the fraud or willful misconduct of Contractor, any Subcontractor, or their
respective employees or Company or its employees, respectively.

      11.5    OTHER PROVISIONS

      The Parties acknowledge and agree that because of the unique nature of the
Facility and the unavailability of substitute facilities, it is difficult or
impossible to determine with precision the amount of damages that would or might
be incurred by Company as a result of Contractor's failure to complete the Work
so that the Facility is completed by the Guaranteed Completion Date or so that
the Facility meets the Performance Guarantee. It is understood and agreed by the
Parties that Company shall be damaged by the failure of Contractor to meet such
obligations and that (i) it would be impracticable or extremely difficult to fix
the actual damages resulting therefrom; (ii) any delay liquidated damages or
performance liquidated damages that are payable under Sections 11.1 and 11.2 of
this Contract are in the nature of liquidated damages, and not a penalty, and
are fair and reasonable; and (iii) such payments represent a reasonable estimate
of fair compensation to Company for the losses that may reasonably be
anticipated from such failure. The Parties hereby acknowledge that this Section
11 represents a reasonable allocation of risk.

SECTION 12 - TITLE; CARE OF THE WORK

      12.1    PASSAGE OF TITLE

      Subject to the provisions of Sections 9.1.1 and 9.4, legal title to and
ownership of all Work and Materials provided hereunder shall pass to and vest in
Company when delivered to the Site and upon payment of the respective milestone
payment pursuant to the Milestone Payment Schedule.

                                     PAGE 27

      12.2    RISK OF LOSS

      Contractor shall be responsible to assure safe delivery of all Materials
to the Site. Except to the extent caused by the gross negligence or willful
misconduct of Company, and provided that any actual proceeds of insurance
payable with respect to loss, damage or destruction shall be paid to Contractor.
Contractor shall bear the risk of physical loss or destruction of or damage to
the Materials and the Work, whether or not incorporated in the Facility at the
Site or located on or off the Site, until such time as care, custody and control
of such equipment or Work is turned over to Company as provided in this
Contract. Notwithstanding the passage of title as provided in Section 12.1,
Contractor assumes the risk of loss with respect to, and shall be obligated to
replace, repair or reconstruct, any portion or all of the Materials or the Work
that is lost, damaged or destroyed prior to turning over care, custody and
control of such Material or Work to Company as provided in Section 12.3 of this
Contract, irrespective of how such loss, damage or destruction shall have
occurred. In the event of a termination of this Contract in accordance with the
provisions hereof prior to such turnover, the risk of loss with respect to such
Materials and Work shall pass to Company upon the effective date of termination,
whether by Company or by Contractor.

      12.3    CARE, CUSTODY AND CONTROL

      Upon Final Acceptance, Contractor will turn over to Company the care,
custody and control of the Facility. It is further acknowledged and agreed that
Company shall provide Contractor, at all times, free and clear access to the
Facility in order to allow Contractor to perform its obligations under the
Contract (including, without limitation, completion and/or repetition of
testing, Punchlist Items and warranties); provided that Contractor's performance
of Work after Final Acceptance does not unreasonably interfere with the
commercial operation of the Facility.

SECTION 13 - INSURANCE

      13.1    CONSTRUCTION INSURANCE

      Company and/or Contractor shall:

              (a)    obtain and maintain in full force and effect, at its own

              (b)    procure and maintain such further coverages as Company or
Contractor is required to have by any applicable Law.

                                     PAGE 28

      In the event this insurance or any portion of it becomes commercially
unavailable, Company and Contractor shall cooperate to obtain such replacement
insurance as may be available and this Contract shall be modified accordingly.

      13.2    POLICIES

      Construction insurance shall:

equivalent:

              "Where more than one party comprises the "Insured," each of the
parties shall, for the purpose of such insurance, be considered as a separate
and distinct unit/entity, and the words "the Insured" shall be considered as
applying to each party in the same manner as if a separate policy has been
issued to each of the said parties. The insurer will provide indemnity to each
in the same manner and to the same extent as if a separate policy has been
issued to each, provided that the total amount payable in respect of
compensation shall not exceed the limits of indemnity";

it.

      13.3    PAYMENT OF DEDUCTIBLES

entitled to cause its insurers or agents to provide to Company the certificates
of insurance evidencing its builders all risk policy only when the relevant risk
arises. Failure by a Party to obtain the insurance coverage or certificates of
insurance required by this Section 13 shall not in any way relieve or limit such
Party's obligations and liabilities under this Contract, nor shall the failure
of any insurance company for any reason to pay claims accruing with respect to
such Party's insurance, affect, negate or release such Party from any of the
provisions of this Contract, including such Party's indemnity obligations. The

                                     PAGE 29

shall fail to procure or maintain its insurances, then the other Party shall
have the right (but shall not be obligated) to provide and maintain such
insurance at the defaulting Party's expense and to deduct the cost thereof from
any amount or amounts due to the other Party or in the event there are no such
amounts due and payable, the defaulting Party shall reimburse the other Party
for such costs on demand.

      13.5    SUBCONTRACTORS INSURANCE

      Contractor shall require its Major Subcontractors to, prior to performing
the works for Contractor which necessitate such coverage, provide proper

SECTION 14 - DISPUTE RESOLUTION

      14.1    SETTLEMENT BY MUTUAL AGREEMENT

      Company and Contractor desire that this Contract operate between them
fairly and reasonably. If during the term of this Contract a dispute arises
between Company and Contractor, or one Party perceives the other as acting
unfairly or unreasonably, or a question of interpretation arises hereunder, then
the Parties shall cause the Company's Representative and Contractor's
Representative to promptly confer and exert their good faith efforts to reach a
reasonable and equitable resolution of the issue. If Company's Representative
and Contractor's Representative are unable to resolve the issue within fourteen
(14) Days (within five (5) Days if a payment dispute), the matter shall be
referred within two (2) Days of the lapse of such period to the Parties'
responsible officers for resolution. Neither Party shall seek resolution by
mediation or arbitration of any dispute arising in connection with this Contract
until both Parties' responsible officers, who shall be identified by each Party
from time to time, have had at least fourteen (14) Days (seven (7) Days if a
payment dispute) to resolve the dispute following referral of the dispute to
such responsible officers. If the Parties fail to settle such dispute within
such period (including a failure identify their respective responsible officers
and make necessary referrals within such period), the provisions of Section 14.2
shall apply unless the Parties agree that the dispute is to be resolved
according to the provisions of Section 14.3. During pendency of a dispute,
Contractor shall be obligated to continue performance other than where the
nature or scale of the dispute may materially adversely affect Contractor's
ability to perform, or where such continued performance may materially adversely
affect Contractor's position with respect to the dispute.

      14.2    MEDIATION

      If a dispute under this Contract is not resolved by the Parties pursuant
to Section 14.1, upon the request of either Party the Parties shall try in good
faith to settle the dispute by nonbinding mediation administered by the American
Arbitration Association under its Commercial Mediation Rules before resorting to
arbitration. Unless otherwise agreed upon by the Parties, the mediation shall be
held in Nevada. Each Party will bear the cost and expense of preparing and
presenting its own case (including, but not limited to, its own attorneys' fees
and costs of witnesses). Payment of the mediator and other costs and expenses of
the mediation will be divided equally among the Parties.

      14.3    ARBITRATION

      14.3.1  If a dispute under this Contract is not resolved by the Parties
pursuant to Section 14.2 within thirty (30) Days from the date on which either
Party first requested mediation or if the Parties agree that the dispute is to
be resolved through arbitration, then such dispute shall be finally settled by

                                     PAGE 30

arbitration administered by the American Arbitration Association in accordance
with its Commercial Arbitration Rules. Unless otherwise agreed upon by the
Parties, the arbitration shall be held in Nevada.

      14.3.2  Notice of the demand for arbitration shall be delivered to the
other Party and the dispute shall be referred to such arbitrator, if the Parties
agree upon one, within ten (10) Days of receipt of demand, and if not to three
(3) arbitrators, one appointed by each Party, within ten (10) Days of receipt of
demand, each of such arbitrators to have knowledge and experience in the
construction and power generation field, both in technical matters as well as in
the implementation and interpretation of agreements similar to this Contract,
and a third independent arbitrator appointed by the two (2) arbitrators
appointed by the Parties. If a Party fails to appoint an arbitrator within the
aforementioned term, then the other Party's appointee shall become the sole
arbitrator. The Parties shall proceed with the arbitration expeditiously and
shall conclude all proceedings thereunder in order that a decision may be
rendered within sixty (60) Days or, in the case of a payment dispute, thirty
(30) Days from service of the demand for arbitration. Each Party shall bear its
own expenses in connection with any arbitration, including but not limited to
counsel fees, and all joint expenses shall be apportioned in the award of the
arbitrator(s).

      14.4    PENDING DISPUTES

      Notwithstanding any provision of this Section 14 to the contrary, either
Party may commence litigation within thirty (30) Days prior to the date after
which the commencement of litigation could be barred by any applicable statute
of limitations or other law, rule, regulation, or order of similar import or in
order to request injunctive or other equitable relief in connection with any
bankruptcy or insolvency proceeding or otherwise necessary to prevent
irreparable harm. In such event, the Parties will (except as may be prohibited
by judicial order) nevertheless continue to follow the procedures set forth
herein. While any disputes under this Contract are pending, including the
commencement and pendency of any of the dispute resolution procedures set forth
in this Section 14, the Parties shall abide by all their obligations under this
Contract without prejudice to a final determination in accordance with the
foregoing provisions of this Section 14.

      14.5    AWARDS

      Each Party agrees that any final award against it in any proceedings of
the nature referred to in Section 14.2 or 14.3 shall be final, conclusive, and
binding upon it and may be enforced in any court of competent jurisdiction, by
suit on the award or otherwise, a certified copy of which award shall be
conclusive evidence thereof and of the amount of its liability, or by any other
means provided by law.

SECTION 15 - INDEMNIFICATION

      15.1    CONTRACTOR'S INDEMNITY

default of Company); or

              (b)    any actual or alleged infringement of third party
intellectual property rights (including patents, copyright or trademark
infringement) by reason of the buying or use of any of design or engineering of

(except to the

                                     PAGE 31

extent caused by the use of the Materials or Work other than consistent with the
original purpose for which it is intended or any infringement which is due to
the use of the Materials in association or combination with any other plant or
items not supplied by Contractor).

      15.2    COMPANY'S INDEMNITY

      Company shall defend, indemnify and hold harmless Contractor and its
Subcontractors and their respective joint venture partners, directors, officers,
agents, employees, shareholders and Affiliates from any and all Liability or
Proceedings arising out of:

              (a)    any actual or alleged injury or death of persons or damage

Company (except only to the extent that the same have been caused by the
negligence or default of Contractor or its Subcontractors); or

              (b)    any and all environmental related liability or cost
arising from or related to the Site, including any actual or alleged injury to
persons or property related thereto or any remedial activity (except to the

      15.3    INDEMNIFICATION NOTICE AND SETTLEMENT OF CLAIMS

      A Party seeking the benefit of an indemnity under this Section 15 shall
give the other Party written notice of any claim giving rise to the indemnity
promptly after such Party learns of the same. The indemnifying Party may, at its
own cost, conduct negotiations for the settlement of such claim and any
litigation that may arise therefrom. The Party claiming the benefit of the
indemnity shall not make any admission that might be prejudicial to the
indemnifying Party unless the indemnifying Party fails to take over the conduct
of the negotiations or litigation within a reasonable time after having been so
requested. The indemnifying Party shall not settle any indemnified claim without
the indemnified Party's prior written approval (not to be unreasonably withheld
or delayed). The Party claiming the benefit of the indemnity shall, at the
request of the other Party, provide reasonable assistance for the purpose of
contesting any such claim or action, and shall be paid all reasonable costs
incurred in doing so and shall have the right to have its own counsel, at its
expense, participate in the defense and negotiation of the claim or action.

SECTION 16 - ASSIGNMENT

      16.1    ASSIGNMENT BY COMPANY

      (a) Company may assign or collaterally assign all of its rights, title and
interest in and to or arising out of or in connection with this Contract as
security for financing of the Galena Facility for benefit of Collateral Agent,
and Collateral Agent may further assign such rights to the extent permitted
under the Indenture; provided, however, that any such assignment shall not
relieve Company of any obligation hereunder. If Company collaterally assigns its

will enter into a Consent Agreement with the Collateral Agent containing
reasonable and customary provisions.

      (b) Unless specifically permitted in subsection (a) above, Company may not
assign any or all of its obligations, rights, title and/or interest in and to or

connection with this Contract to an Affiliate, without

                                     PAGE 32

and/or interest in and to or arising out of or in connection with this Contract
shall relieve Company of any obligation hereunder.

      16.2    ASSIGNMENT BY CONTRACTOR

      Contractor may not assign any or all of its obligations, rights, title

Contractor may assign its obligations, rights, title and/or interest in and to
or arising out of or in connection with this Contract to an Affiliate, without
Company's consent. No assignment of Contractor's obligations, rights, title
and/or interest in and to or arising out of or in connection with this Contract

SECTION 17 - SUBCONTRACTORS

      17.1    SUBCONTRACTS

      Contractor may enter into Subcontracts for the performance of the Work and
shall be solely responsible for the satisfactory performance of the Work and the
acts, defaults and omissions of any Subcontractor notwithstanding any review,
approval or other action taken by Company with regard to the selection of a
Subcontractor hereunder. Contractor shall be responsible for the actions of the
Subcontractors in their performance of the Work as if such actions were those of
Contractor. The issuance of any Subcontract shall not relieve Contractor of any
of its obligations under this Contract. All Subcontracts shall be consistent
with and in no way contrary to or inconsistent with any of the terms or
provisions of this Contract. No contractual relationship shall exist between
Company and any Subcontractor with respect to the Work to be performed
hereunder, and no Subcontractor is intended to be or shall be deemed a
third-party beneficiary of this Contract. Except as expressly set forth in
Section 17.2 below, nothing contained herein shall (a) create any contractual
relationship between any Subcontractor and Company or (b) obligate Company to
pay or arrange for the payment of any Subcontractor.

      17.2    SUBCONTRACT PROVISIONS

      Contractor shall ensure that Subcontracts made with Major Subcontractors

Subcontract are assignable to Company, its successors and assigns upon Company's
written request accompanied by proof of source of payment to Major
Subcontractor's satisfaction, following any termination of this Contract.

                                     PAGE 33

SECTION 18 - SUSPENSION

      18.1    RIGHT OF COMPANY TO SUSPEND WORK

      Company may suspend performance of the Work by Contractor hereunder, in
whole or in part, upon ten (10) Days' prior written notice of such suspension to
Contractor. Such suspension shall continue for the period specified in the
suspension notice.

      18.2    INITIAL PAYMENTS TO CONTRACTOR

      Within thirty (30) Days of the issuance of an invoice therefor by
Contractor, Contractor shall be entitled to payment for Work that has been
completed as of the effective date of such suspension or concerning which
delivery has been suspended if such suspension has not ceased within ten (10)
Days of the effective date of such suspension.

      18.3    EXTENDED SUSPENSION

      In the event that the duration of the suspensions by Company exceed ninety
(90) Days in the aggregate, then Contractor may give notice to the Company's
Representative and Collateral Agent requesting permission to proceed. If
permission is not granted by Company or Collateral Agent within twenty (20) Days
of the delivery of such notice, Contractor may terminate its obligations under
this Contract by so notifying Company in writing, and Contractor shall be
entitled to payments as described in Section 19.2.2.

      18.4    RIGHT OF CONTRACTOR TO SUSPEND

      Contractor may suspend performance of the Work hereunder, in whole or in
part, upon five (5) Days' prior written notice to Company of such suspension (i)
where Company has withheld from payment any amount invoiced by Contractor where
Company's Representative is in receipt of such invoice and the invoiced amount
has become due, unless within fifteen (15) Days of the due date of such amount
Company has released such payment or such withheld payment has been set aside
for payment to Contractor in a form acceptable to Contractor pending resolution
of the dispute in accordance with the dispute resolution procedures set forth in
Section 14 or (ii) Collateral Agent suspends disbursements of monies to Company
as the result of an event of default under the Indenture not attributable to
Contractor and Company has not provided Contractor reasonable assurance of
payment from other sources. Such suspension shall continue for the period
specified in the suspension notice.

      18.5    ADDITIONAL CHANGES RESULTING FROM SUSPENSIONS

      Provided that suspension is not necessary by reason of a default on the
part of Contractor that has not been corrected, in the event of suspension
pursuant to this Section 18, the Contract Price shall be increased by the amount
equal to the additional costs reasonably incurred by Contractor as a result of
the suspension (including without limitation costs for the purpose of
safeguarding, storage, personnel, Subcontractors or rented equipment costs,
demobilization and re-mobilization costs and increased costs or charges incurred
for rescheduling) and the scheduled dates specified in this Contract, the
Schedule, and all other dates and milestones herein by which Contractor's
responsibilities are measured shall be adjusted to reflect any delays resulting
from such suspension (including without limitation a period equal to the
suspension period, a period for demobilization and re-mobilization plus any
additional period required). If Contractor shall, solely in consequence of such
suspension, be required to perform any obligations under its warranty at a time
which exceeds the original schedule for warranty obligations that would have
been applied if there were no suspension, the additional cost of complying with
the warranty obligations shall be added to the Contract Price.

                                     PAGE 34

      18.6    RESUMPTION OF WORK

      Upon receipt of notice to resume the Work in accordance with this
Contract, Contractor shall examine the Facility and the Work affected by the
suspension. Contractor shall make good any deterioration or defect in or loss of
such Facility or Work that may have occurred during suspension, and costs
incurred in making such examinations and making good and resuming Work shall be
added to the Contract Price, all of which Work shall be at Company's expense
unless such suspension occurred by reason of a default on the part of Contractor
that was not corrected within the time period specified in Section 19.1.

SECTION 19 - TERMINATION

      19.1    TERMINATION BY COMPANY

      19.1.1  Company may terminate the Work after the occurrence of one or
more of the following events of default and if, following a written notice from
Company to cure such event of default, said event of default continues to exist
for ten (10) Days in the circumstances described in (a) below, and thirty (30)
Days in the circumstances described in (b) below:

              (a)    the occurrence of an Insolvency Event involving Contractor;
or

              (b)    Contractor defaults in its performance under a material
provision of this Contract, including (i) total abandonment of the Facility and
Work; (ii) a representation or warranty provided by Contractor herein is or
becomes untrue in any material respect; or (iii) due to a Contractor failure,
the Facility does not achieve Commercial Operation (as such term is defined in
the PPA) by the date which is 150 days prior to the date for which termination
for default in achieving such milestone by the offtaker may occur under the
terms of the PPA; provided, however, that where a specific remedy is provided
under the Contract, enforcement of the specific remedy shall be the sole
recourse and remedy for such default, and provided, further, that Company may
not terminate this Contract until the date that is one hundred twenty (120) days
after such breach (which shall be reduced to thirty (30) days under clause (ii)
above, and sixty (60) days under clause (iii) above) if, after notice of such
default and prior to expiration of the thirty (30) Day period set forth above,
Contractor has commenced and is diligently pursuing efforts to cure such breach.

      19.1.2  In the event of termination as provided in Subsection 19.1.1,
Company shall compensate Contractor for all payment milestones achieved plus a
pro rata portion of the payment milestone amounts for payment milestones
partially achieved as of termination, plus a proportional payment of the unpaid

other costs associated with the termination of the Work. Upon termination and
such payment, Contractor shall deliver to Company possession of the Work in its
then condition, including Drawings and Specifications and contracts with
Subcontractors, and construction supplies dedicated solely to construction of
the Facility.

      19.1.3  In the event of termination as provided in Section 19.1.1,
Company shall have the right, at its sole option, to take possession of all
Materials, assume and become liable for any reasonable written obligations and
commitments that Contractor may have in good faith undertaken with third parties
in connection with the Work, which obligations and commitments are by Law or by
their terms assumable by Company and are not covered by the payments made to
Contractor under Section 19.1.2. If Company elects to assume any obligation of
Contractor as described in this Section 19.1.3, then as a condition precedent to
Company's compliance with any subsection of this Section 19, Contractor shall
execute all papers and take all other reasonable steps requested by Company that
may be required to vest in Company all rights, set-offs, benefits and titles
necessary to such assumption by Company of such

                                     PAGE 35

obligations. Company agrees to indemnify and hold Contractor harmless against
any Liability under any obligations assumed by Company pursuant hereto.

      19.1.4  In the event of termination as provided in Section 19.1.1, if such
sums have not already been offset against monies payable to Contractor,
Contractor shall pay Company the difference between (x) reasonable amounts
incurred by Company to engage a substitute contractor, including overhead,
legal, engineering and other direct and necessary expenses to complete the Work
minus (y) the unpaid Contract Price.

below, and thirty (30) Days in the circumstances described in (b) below:

              (a)    the occurrence of an Insolvency Event involving Company; or

              (b)    Company defaults in its performance under a material
provision of this Contract, and such default is an Uncontrollable Company
Default or is a default of the obligation to make any payment hereunder;
provided, however, that, for all cases except for the obligation to make or
complete any payment, Contractor may not terminate this Contract until the date
that is one hundred twenty (120) days after such breach if, after notice of such
default and prior to expiration of the thirty (30) Day period set forth above,
Company has commenced and is diligently pursuing efforts to cure such breach.

      19.2.2  In the event of termination as provided in Section 19.2.1,
Company shall pay to Contractor that portion of the Contract Price associated
with all payment milestones achieved plus a pro rata portion of the payment
milestone amounts for payment milestones partially achieved up to the date of
Contractor's receipt of notice of termination plus a proportional payment of the
Final Acceptance milestone and plus any costs attributable to and incurred in
terminating the Work, including cancellation charges owed to third parties and
additional compensation in the amount of fifteen percent (15%) for the portion
of the Contract Price paid or payable as provided above, but in no event shall
the total amount exceed the Contract Price. If all such payments are not
received within thirty (30) Days of termination, without derogation from other
remedies available to Contractor, the license granted to Company under Section
9.4 shall automatically terminate and be of no further effect.

SECTION 20 - FORCE MAJEURE

      20.1    CONSEQUENCES OF FORCE MAJEURE

      20.1.1  Upon an occurrence of an event of Force Majeure that materially
and adversely affects the performance by that Party of its obligations or the
enjoyment by that Party of its rights pursuant to this Contract, provided that
any such material adverse effect has not occurred due to the material failure of
the Party to comply with its obligations hereunder, then:

      (a)     the non-performing Party shall use its reasonable efforts to give
the other Party as soon as reasonably practicable but in any event within
seventy-two (72) hours of such Party learning of the occurrence of such event or
circumstance written notice describing the particulars of the occurrence or
circumstance;

                                     PAGE 36

      (b)     the non-performing Party shall be excused from performance
provided that such excused performance is of no greater scope and of no longer
duration than is required by the event of Force Majeure;

      (c)     the non-performing Party shall use its reasonable efforts to
remedy its inability to perform; and

      (d)     when the non-performing Party is able to resume performance of
its obligations under this Contract, that Party shall use its reasonable efforts
to promptly give the other Party written notice to that effect and shall
promptly resume performance.

      20.1.2  Except for the obligations of either Party to make any required
payment then due and owing under this Contract, neither Party shall be liable
for any failure or delay in complying with its obligations hereunder to the
extent that such failure or delay has been caused, or contributed to, by one or
more events of Force Majeure or its or their effects or by any combination
thereof. The periods allowed for the performance by the Parties of such
obligation(s), including without limitation the Guaranteed Completion Date in
the case of Contractor, shall be extended as required, but in no event less than
on a Day-for-Day basis, for so long as one or more Force Majeure events
continues to affect materially and adversely the performance of such Party of
such obligation(s) under or pursuant to this Contract; provided that either
Party may immediately terminate this Contract and Company shall pay Contractor
the amounts described in Section 19.2.2, deducting from such payment only the
unrealized percentage (if any) of the Contract Price, if one or more Force
Majeure events delays a Party's performance for a period greater than nine (9)
Months.

      20.2    ADJUSTMENTS TO DATES AND COST

      In the event Contractor is delayed or the cost of the Work shall be
increased by an event of Force Majeure, Contractor shall be entitled to an
adjustment of the Schedule and the Contract Price shall be increased to reflect
the increase in the cost of the Work and added expenses incurred by Contractor
for additional interest during construction.

milestones including Final Acceptance.

      2.3     SUPPLY

              The Facility will contain 2 OECs (otherwise termed as "ITLUs")
              units, as well as the balance of Plant equipment and materials
              detailed herein.

              The scope of supply includes the following:

              2.3.1  OEC units

                     Two (2) complete OEC units, each OEC unit consists of the
                     following main components:

                     o   Vaporizers

                         The vaporizer is a horizontal, shell and tube heat
                         exchanger, manufactured of carbon steel with a tube
                         bundle, sheet metal shell and fixed tube sheets.
                         Heating fluid flows through the tube side and motive
                         fluid through the shell side. A bellow type expansion
                         joint is provided to compensate for any differential
                         thermal expansion of the tubes and shell.

                         Separator is installed on the top of the vaporizer. The
                         separator is designed to retain the droplets of liquid
                         carried over the vapor, thus preventing impinging of
                         droplets on turbine blades.

                     o   Preheaters

                         The preheater is a horizontal, shell and tube heat
                         exchanger manufactured from carbon steel with a tube
                         bundle, metal shell and fixed tube sheets. Heating
                         fluid flows through the tube side and motive fluid
                         through the shell side. A bellow type expansion joint
                         is provided to compensate for any differential thermal
                         expansion of the tubes and shell.

                     o   Recuperator

                         The recuperator is a horizontal, shell and tube heat
                         exchanger manufactured from carbon steel with a tube
                         bundle, metal shell and fixed tube sheets. Liquid
                         motive fluid flows through the tube side and vapor
                         motive fluid through the shell side.

                     o   Air Cooled condensers

                                    PAGE A-8

                         The condenser is an induced draft, air-cooled heat
                         exchanger. The tubes are arranged in a one-pass
                         configuration where motive fluid vapor is fed from the
                         inlet box to the tubes. The motive fluid is cooled and
                         condensed inside the tubes by forced air flowing
                         outside of the finned tubes in a cross-flow pattern.
                         The condensed motive fluid accumulates in the hot well
                         collector from where it flows by gravity to the motive
                         fluid filters and pumps. The condenser tubes are made
                         of carbon steel tubes with aluminum fins.

                     o   Power skid consists of 2 turbines, one synchronous
                         generator and one oil system

                         Each OEC power skid consists of a dual shaft extension
                         generator, two turbines and associated oil system.

                         (A) SYNCHRONOUS GENERATOR

                         The generator is a synchronous type, air-cooled, three
                         phase machine, brushless and weather protected. It is
                         built to NEMA II specifications and rated at kW, 0.85
                         PF, 13.8 kV and 60 Hz. It is cooled by a once-through
                         air-cooling system with an inlet filter. The generator
                         and the two turbines are directly coupled.

                         (B) TURBINE

                         Each of the two OEC turbines consists of a single
                         casing, multi-stage axial unit. The turbine is directly
                         coupled to the end of the generator shaft. No
                         speed-reducing gearbox is required because the
                         properties of the organic fluids produce favorable
                         aerodynamic matching at relatively low blade and
                         rotational speeds. A double, mechanical shaft seal is
                         used to prevent leakage of the working fluid into the
                         atmosphere or lube oil.

                         (C) TURBINE AND GENERATOR OIL SYSTEM. The oil system
                         has two functions:

                     o   To supply oil to each turbine bearing for lubrication,
                         sealing and cooling, and

                     o   To supply oil to the generator bearings for
                         lubrication.

                         The oil system is designed to supply each oil consumer
                         with the proper pressure and flow, and the proper type
                         of oil. Each system is equipped with an oil pump as
                         well as oil filters, oil coolers (forced air-cooled
                         type), solenoid operated control valves and relief
                         valves. The system is

                                    PAGE A-9

                         equipped with air operated emergency pumps and air
                         accumulator to supply the lube oil in the event of an
                         electric power failure.

                     o   Motive feed pump system including motive fluid pumps
                         and piping.

                         The feed pump is a motor-driven multi stage vertical
                         turbine centrifugal pump, which transfers the
                         condensate motive fluid from the condenser liquid
                         collector into the heat exchangers. A mechanical seal
                         separates the high-pressure motive fluid from the
                         atmosphere.

                         The pump discharge is connected to the recuperator
                         or preheater inlet through level control valve and
                         swing check valve.

                         A manual valve is installed at the suction strainer
                         inlet to allow maintenance of the strainer and the
                         pump.

                     o   Organic Motive Fluid Piping system

                         The organic motive fluid piping system consists of
                         piping assemblies, in which the condensed motive fluid
                         flow from the feed pumps through the recuperator and
                         preheater to the vaporizer, vapor motive fluid flow
                         from the vaporizer to the turbine and from the turbine
                         to the air cooled condenser and in which the condensed
                         motive fluid return from the condenser hot well to the
                         feed pumps. A motive fluid strainer is installed
                         between the hot well collector and the pump inlet.
                         Expansion joints are installed in the turbine inlet and
                         outlet pipe assemblies to reduce the force and moments
                         on the turbine nozzles. Automatic and manual control
                         valves are supplied as part of the piping system.

                     o   Purge system

                         The purge system is installed on the upper side of the
                         condenser outlet boxes. The system is designed to
                         continuously purge the OEC condenser of non-condensable
                         gases, predominantly air, that enter the OEC, mostly
                         during start-up and when the unit is not operating, and
                         to recover the working fluid.

                     o   Power and control system

                                    PAGE A-10

                         (OEC power and control cabinets may be installed in
                         either pre-fabricated power shelters (one per each
                         unit) or inside one main building in the power plant).

                         The OEC power system contains of: (i) the generator
                         high voltage breaker, PTs and CTs; (ii) Protection
                         relays board and (iii) 480 Volt auxiliaries supply
                         board (MCC).

                         The control system is based on a programmable logic
                         controller (PLC). The OEC control incorporates a
                         turbine control backup relay (TCBU), which disconnect
                         the OEC from the bus and shut it down safely in event
                         of a PLC malfunction. The PLC and I/O units with its
                         accessories, is housed in a control board and fields
                         junction boxes.

                         The OEC control and protection system contains the
                         following items:

                         (a)  PLC: central processing unit with analog and
                         digital input and output modules, and communication
                         control units.

                         (b)  PROTECTION RELAYS to provide generator protection
                         against under/over voltage, reverse power, loss of
                         excitation, generator differential, phase over current,
                         ground fault, phase balance, over speed, etc.

                         (c)  SYNCHRONIZER, check synchronizer, voltage
                         regulator and VAR controller, and

                         (d)  OPERATION MODE SELECTOR switch and reset push
                         buttons for local operation. Same switch and push
                         buttons are duplicated by soft switch at the HMI
                         computer screen for remote operation of the OEC from a
                         local control room.

                         The control system automatically accelerates the
                         generator to synchronous speed and then synchronizes
                         the generator to the bus. After being linked with the
                         bus, the control system monitors and controls the
                         operation of the OEC. Pressures, temperatures,
                         voltages, speed, kilowatts, kilovars, currents, etc.,
                         are checked and monitored and compared with preset
                         values in memory, to detect warning or failure
                         conditions.

                         In the event of a failure within the system, the unit
                         is

                                    PAGE A-11

                         disconnected from the bus and shut down in a
                         pre-programmed sequence. After a failure condition is
                         rectified, the generating unit can be automatically
                         started after a manual reset signal.

                     o   Electro-Pneumatic Control System

                         The electro-pneumatic control system operates the
                         control valve actuators and provides air pressure to
                         pneumatic components, either directly or through
                         solenoid-operated valves installed on the pneumatic
                         control panel. The pneumatic control panel is supplied
                         by air at a nominal pressure of 90 psi, the pressure
                         required to operate the pneumatic equipment. Pressure
                         regulation and filtration is also provided.

                         Electronic control signals for the system are provided
                         from the central unit control in the form of digital
                         (ON, OFF) or analog (4 to 20 mA). The analog signals
                         are converted by current to pressure (I/P) transducers
                         to a proportional pneumatic output signal.

                         The system includes a personal computer with dedicated
                         software to enable the operator to operate the power
                         plant and monitor its functions.

                     o   Interface With Local / Remote Station Controls

                         The control system provides access to all the analog
                         and digital signals connected to the PLC through a
                         communication link. Using the communication link,
                         Company can monitor parameters inside the PLC, send the
                         OEC Stop Command from another PC with the proper
                         software. The data inside the PLC is organized in
                         blocks of accessible registers. Detailed requirements
                         for the data transfer of information are determined
                         during detailed design. This includes both
                         communication and hard-wired interface data.

                     o   Instrumentation

                         All parameters that are measured to insure proper

                 resetting the same, it shall be started again according to the
                 normal hot start procedure as described in O&M manuals, and
                 resume normal operation conditions.

            The test will be recorded as per the attached test record of each
            Generating Unit Test for each Generating Unit.

      3.2   Net Deliverable Energy Test (Performance Test)

            After completion of the Mechanical Completion Tests and the
            Generating Unit Tests, the Facility will be tested as close as
            possible to the Design Conditions, for a period of ninety six (96)
            hours at full rated load to verify the Facility's Net Deliverable
            Energy. The ambient temperature and the heat source conditions will
            be within the Design Range.

            During this test, the net deliverable energy of the Facility will be
            monitored, with manual and automatic recording of readings as
            specified in Section 6.4 hereof.

4.    TEST PROTOCOLS

      The procedures for conducting the tests, including calibration data,
      instrumentation data, test records and frequency of measurement will be
      detailed in individual test protocols. The individual test protocol will
      be drafted by Contractor and submitted for review to Company and the
      Independent Engineer at least forty five (45) days prior to the start of
      any individual test. All components of the test protocol, including
      revisions, must be approved by Company and the Independent Engineer at
      least fifteen (15) days prior to the commencement of the relevant test.
      The test protocols will be consistent with the terms of this Exhibit D.

                                    PAGE D-3

      The test protocols shall explicitly state the industry codes and standards
      that will be used, the instrumentation required, the form of the expected
      results, the anticipated time duration of the test and the anticipated
      number of Company's operating personnel required to assist Contractor in
      the conduct of the test.

                                    PAGE D-4

5.    REPEATING AND SUSPENSION OF TEST

      If test criteria are not met or problems or deficiencies arise during the
      conduct of the tests which require cessation thereof (including due to
      Company Default, causes attributable to other entities such as Nevada
      Power Co. and Force Majeure), or if Contractor opts to retest to improve
      test results, Contractor will establish the actions to be taken to bring
      about a successful completion of the tests. Such actions shall be taken by
      Contractor and the tests shall be reconducted.

      Subject to the provisions of the Contract, Contractor may repeat any of
      the tests. In case one or more of the tests are repeated, the latest of
      the test results will be utilized to establish the final results of
      testing. Repeating one or more of the tests does not require repeating any
      of the other tests, unless it affects the results of tests already
      performed.

      Subject to the provisions of the Contract, the tests may be suspended by
      Contractor upon each occurrence or circumstance beyond the control of
      Contractor which does not reflect equipment failure, design or
      construction defects (e.g., a problem with the grid, supply of heat
      resource not in accordance with the design range, Force Majeure, etc.),
      which make conduct of the tests unfeasible. The test period may resume
      after the period(s) of suspension, with the test period including
      period(s) of Facility test operation both before and after the period(s)
      of suspension, if Contractor so desires. Alternatively, at Contractor's
      discretion, the tests may be repeated from the beginning following a
      suspension.

      Adjustments to the Facility during suspension shall not impact on the
      availability of the Facility to resume the tests when the causes of
      suspension no longer exist unless Contractor elects to repeat the tests
      from the beginning.

6.    INSTRUMENTATION

      Permanent Facility instrumentation shall be utilized for measurement and
      data collection. A list of key instruments to be used during the tests
      will be specified by Contractor prior to the initiation of the test. The
      instruments will be calibrated in accordance with the standards of a
      recognized national organization such as the American Society of Testing
      and Materials (ASTM), the Instrument Society of America (ISA), etc.

      6.1   Instrumentation Uncertainty

            Solely for purposes of the tests, the following as installed
            Facility instrumentation will be deemed to have the
            after-calibration uncertainties below:

Terms not specifically defined in this Exhibit shall have the meaning described
in the general terms of the Engineering, Procurement and Construction Contract
to which this Exhibit is attached.

1.    Where Company has agreed in accordance with the terms of the Contract to
take corrective action, and upon notifying Contractor as set forth in Section
10.3.1 of the Contract, Company may undertake corrective action, but Contractor
reserves the right to investigate and determine the eligibility of such warranty
claim.

2.    Company shall notify Contractor in accordance with Section 10.3.1 of the
Contract and provide documents per paragraph (3) below together with a written
cost estimate of the corrective action required. As soon as reasonably possible
following the receipt of said documents and cost estimate, Contractor shall
investigate the defect and shall issue written instructions to Company on the
corrective action to be undertaken, or Contractor shall undertake corrective
action by its own employees or agents.

3.    The following procedures shall be observed in all Contractor warranty
claims for the Facility in connection with which Company has taken corrective
action at Contractor's request as identified in paragraph (1) above:

      (a)  A failure report, which shall contain technical and logistic
information sufficiently detailed to enable Contractor to assess the damage to
the Work and to evaluate appropriate corrective action in the form as agreed to
by Company and Contractor, shall be provided by Company as soon as reasonably
practicable after the occurrence of any event giving rise to a warranty claim.

      (b)  Warranty claims shall be submitted in accordance with paragraph (d)
below, and shall include, as a required minimum, the following documents:

           (i)   Applicable failure report;

           (ii)  List of equipment and materials purchased or used in
accomplishing the repair, schedule of operations and subcontractors hours
applicable to each claim, and a copy of any internal work orders or purchase
orders prepared in connection with each such claim;

           (iii) Company's maintenance and repair records with respect to the
equipment for which the claim is being made;

           Company shall include with such maintenance and repair records the
manufacturer/vendor part number and serial number and the identification by part
number and serial number of the next major assembly call-out (such as, but not
limited to, turbine, generator, electrical cabinet); and

           (iv)  copies of invoices received or prepared for costs and expenses
claimed.

      The documentation to be provided pursuant to paragraphs (b)(ii) and
(b)(iii) above, shall be in a form reasonably acceptable to Contractor.

      (c)  All warranty claims pertaining to failure of the equipment for which
Company has independently undertaken corrective action during any calendar month
shall be submitted to Contractor on or before the last day of the following
calendar month. Claims shall be paid by Contractor on a net 30 basis. Work
performed by Company under a warranty claim shall be billed on a "time and
material" basis as defined below.

      (d)  "Time and Material" in connection with a warranty claim is defined as
follows:

                                    PAGE E-2

            (i)  With respect to "Time", the product of one hundred fifteen
percent (115%) of the normal hourly wage (including fringe benefits, insurance
and taxes) Company pays with respect to its particular employee (not including
overhead) multiplied by the number of hours each employee performed the
particular Work;

           (ii)  With respect to "Material", one hundred ten percent (110%) of
the actual purchase price paid by Company or an affiliate to a third party for
the materials incorporated or consumed in connection with the Work; and

           (iii) With respect to Work performed by a subcontractor (other than
an entity which directly or indirectly controls, is controlled by, or is under
common control with, Company, Work done by any such entity being deemed Work
done by Company through its own employees for purposes of this definition), one
hundred ten percent (110%) of the actual amount paid by Company to the
subcontractor for such Work.

      (e)  Accounting settlement between Company and Contractor due to warranty
claims shall occur on a quarterly basis.

      (f)  Company shall maintain adequate records to support all warranty
claims and allow Contractor to audit warranty claims upon no less than ten (10)
days period notice.

                                FORM OF GUARANTY

            This ENGINEERING, PROCUREMENT AND CONSTRUCTION AGREEMENT GUARANTY,
made and delivered as of February 12, 2004 (this "Guaranty"), is by ORMAT
TECHNOLOGIES INC., a Delaware corporation (the "Guarantor"), in favor of ORNI 7
LLC, a Delaware limited liability company (together with its successors in such
capacity, the "Guaranteed Party").

            WHEREAS, the Guaranteed Party and Ormat Nevada Inc., a Delaware
corporation, as contractor (the "Contractor"), are parties to an Engineering,
Procurement and Construction Agreement dated as of the date hereof (as modified
and supplemented and in effect from time to time, the "EPC Agreement").
Capitalized terms used in this Guaranty but not otherwise defined herein shall
have the meanings assigned to such terms in the EPC Agreement.

            WHEREAS, the Guarantor has agreed to provide assurance for the
performance of the Contractor's obligations in connection with the EPC
Agreement; and

            WHEREAS, the execution and delivery of this Guaranty is a condition
to the Guaranteed Party's further performance of its obligations under the terms
of the EPC Agreement.

            NOW, THEREFORE, in consideration of the premises and other good and
valuable consideration, the adequacy, receipt and sufficiency of which are
hereby acknowledged, the Guarantor hereby agrees as follows:

            1.   Guaranty. The Guarantor hereby unconditionally and irrevocably
guarantees, as the primary obligor and not merely as surety, to and for the
benefit of the Guaranteed Party, the timely performance when due by the
Contractor of all obligations, whether financial or non-financial, required to
be performed by it under the EPC Agreement, including, without limitation, the
due and punctual payment in full by the Contractor of all amounts required to be
paid by it thereunder (the obligations guaranteed hereunder hereinafter referred
to as the "Guaranteed Obligations"). The guaranty contained herein is an
absolute, unconditional, present and continuing guaranty of payment and
performance, and not of collection, is in no way conditioned or contingent upon
any attempt to collect from or enforce payment or performance by Contractor or
upon any other event, contingency or circumstance whatsoever, and shall be
binding upon and against the Guarantor without regard to the validity or
enforceability of the EPC Agreement. If, for any reason whatsoever, the
Contractor shall fail or be unable duly, punctually and fully to pay or perform
any Guaranteed Obligation as and when the same shall become due and payable or
when such performance shall be required under the EPC Agreement, the Guarantor
shall forthwith pay,

                                    PAGE I-1

perform, cause to be paid, or cause to be performed, such Guaranteed Obligation
to the Guaranteed Party.

            2.   Guaranty Absolute. The Guarantor agrees that the obligations of
the Guarantor set forth in this Guaranty shall be direct obligations of the
Guarantor, and such obligations shall be absolute and unconditional, shall not
be subject to any counterclaim, set-off, deduction, diminution, abatement,
recoupment, suspension, deferment, reduction or defense (other than to the
extent available to Contractor under the EPC Agreement) based upon any claim the
Guarantor may have against the Guaranteed Party and shall remain in full force
and effect without regard to, and shall not be released, discharged or in any
way affected or impaired by, any circumstance or condition whatsoever (other
than full and strict compliance by the Guarantor with its obligations hereunder
as expressly provided herein, provided, however, that the Guarantor shall be
entitled to assert as a defense to performance any defenses to performance
available to Contractor under the EPC Agreement), including, without limitation:

                 (a)  any amendment or modification of or supplement to or other
      change in the EPC Agreement or any exhibit attached thereto;

                 (b)  any failure, omission or delay on the part of the
      Guaranteed Party to conform or comply with any term of the EPC Agreement
      or any exhibit attached thereto;

                 (c)  any waiver, consent, extension, indulgence, compromise,
      release or other action or inaction under or in respect of the EPC
      Agreement or any obligation or liability of the Guaranteed Party, or any
      exercise or non-exercise of any right, remedy, power or privilege under or
      in respect of the EPC Agreement or any such obligation or liability,
      provided that the Guaranteed Obligations will be deemed waived, extended,
      released, terminated, liquidated or otherwise amended to the extent of an
      express agreement or consent to in writing for the same by Contractor, the
      Guaranteed Party and the Collateral Agent.

                 (d)  any bankruptcy, insolvency, reorganization, arrangement,
      readjustment, liquidation or similar proceeding with respect to the
      Contractor, the Guarantor, the Guaranteed Party or any of their respective
      properties, or any action taken by any trustee or receiver or by any court
      in any such proceeding;

                                    PAGE I-2

                 (e)  any discharge, termination, cancellation, frustration,
      irregularity, invalidity or unenforceability, in whole or in part, of the
      EPC Agreement or any exhibit attached thereto or any term or provision
      thereof (other than as a result of the performance or payment in full of
      the Guaranteed Obligations or as a result of an express agreement or
      consent to in writing for the same by Contractor, the Guaranteed Party and
      the Collateral Agent);

                 (f)  any merger or consolidation of the Guarantor, the
      Guaranteed Party, or the Contractor into or with any other corporation or
      any sale, lease or transfer of all or any of the assets of the Guarantor,
      the Guaranteed Party, or the Contractor;

                 (g)  any change in the ownership of the Guarantor, the
      Guaranteed Party, or the Contractor; or

                 (h)  to the extent permitted under applicable Laws, any other
      occurrence or circumstance whatsoever, whether similar or dissimilar to
      the foregoing, which might otherwise constitute a legal or equitable
      defense available to, or discharge of the liabilities of, the Contractor
      or the Guarantor as a guarantor or surety which might otherwise limit
      recourse against the Guarantor in respect of the Guaranteed Obligations,
      other than performance in full of the Guaranteed Obligations.

            The Guaranteed Obligations constitute the full recourse obligations
of the Guarantor enforceable against it to the full extent of all its assets and
properties. Without limiting the generality of the foregoing, the Guarantor
agrees that repeated and successive demands may be made and recoveries may be
had hereunder as and when, from time to time, the Contractor shall default
under, or fail to comply with, the terms of the EPC Agreement and that
notwithstanding the recovery hereunder for or in respect of any given default or
failure to so comply by the Contractor under the EPC Agreement, this Guaranty
shall remain in full force and effect and shall apply to each and every
subsequent default. If (i) an event permitting the exercise of remedies under
the EPC Agreement, as the case may be, shall at any time have occurred and be
continuing and (ii) such exercise, or any consequences thereof provided in the
EPC Agreement, shall at any time be prevented by reason of the pendency against
the Contractor of a case or proceeding under any bankruptcy or insolvency law,
the Guarantor agrees that, solely for purposes of this Guaranty and its
obligations hereunder, the EPC Agreement shall be deemed to have been declared
in default and obligations thereunder shall be deemed to be due and payable,
with all the attendant consequences as provided in such EPC Agreement as if
declaration of default and the consequence thereof had been accomplished in
accordance with

                                    PAGE I-3

the terms thereof, and the Guarantor shall, upon demand, forthwith perform the
obligations guaranteed hereunder.

            The obligations of the Guarantor hereunder are several from the
Contractor or any other person, and are primary obligations concerning which the
Guarantor is the principal obligor. There are no conditions precedent to the
enforcement of this Guaranty, except as expressly contained herein. It shall not
be necessary for the Guaranteed Party, in order to enforce payment by the
Guarantor under this Guaranty, to show any proof of the Contractor's default, to
exhaust its remedies against the Contractor, any other guarantor, or any other
person liable for the payment or performance of the Guaranteed Obligations.

            In no case shall the Guarantor be liable under this Guaranty or in
respect of the Guaranteed Obligations to an extent greater than the Guaranteed
Obligations.

            3.   Waiver. The Guarantor hereby unconditionally waives, to the
extent permitted by applicable Laws:

                 (a)  notice of any of the matters referred to in Section 2
      hereof;

                 (b)  all notices which may be required by Laws now or hereafter
      in effect, to preserve any rights of the Guarantor hereunder, including,
      without limitation, any demand or proof of notice of non-payment or

      legality, validity, binding effect or enforceability hereof.

                 (d)  This Guaranty has been duly executed and delivered by the
      Guarantor and constitutes the legal, valid and binding obligation of the

      knowledge of the Guarantor, threatened, against or affecting the Guarantor

      under this Guaranty;

                 (b)  comply with all the requirements of all applicable Laws,
      except where the failure to comply with any such requirement would not

      2.3     SUPPLY

              The Facility will contain 2 OECs (otherwise termed as "ITLUs")
              units, as well as the balance of Plant equipment and materials
              detailed herein.

              The scope of supply includes the following:

              2.3.1  OEC units (New units in Galena)

                     Two (2) complete OEC units, each OEC unit consists of the
                     following main components:

                     o   Vaporizers

                         The vaporizer is a horizontal, shell and tube heat
                         exchanger, manufactured of carbon steel with a tube
                         bundle, sheet metal shell and fixed tube sheets.
                         Heating fluid flows through the tube side and motive
                         fluid through the shell side. A bellow type expansion
                         joint is provided to compensate for any differential
                         thermal expansion of the tubes and shell.

                         Separator is installed on the top of the vaporizer. The
                         separator is designed to retain the droplets of liquid
                         carried over the vapor, thus preventing impinging of
                         droplets on turbine blades.

                     o   Preheaters

                         The preheater is a horizontal, shell and tube heat
                         exchanger manufactured from carbon steel with a tube
                         bundle, metal shell and fixed tube sheets. Heating
                         fluid flows through the tube side and motive fluid
                         through the shell side. A bellow type expansion joint
                         is provided to compensate for any differential thermal
                         expansion of the tubes and shell.

                     o   Recuperator

                         The recuperator is a horizontal, shell and tube heat
                         exchanger manufactured from carbon steel with a tube
                         bundle, metal shell and fixed tube sheets. Liquid
                         motive fluid flows through the tube side and vapor
                         motive fluid through the shell side.

                     o   Air Cooled condensers

                         The condenser is an induced draft, air-cooled heat
                         exchanger. The tubes are arranged in a one-pass
                         configuration where motive fluid vapor is fed from the
                         inlet box to the tubes. The motive fluid is cooled and
                         condensed inside the tubes by forced air flowing
                         outside of the finned tubes in a cross-flow pattern.
                         The condensed motive fluid accumulates in the hot well
                         collector from where it flows by gravity to the motive
                         fluid filters and pumps. The condenser tubes are made
                         of carbon steel tubes with aluminum fins.

                     o   Power skid consists of 2 turbines, one synchronous
                         generator and one oil system

                         Each OEC power skid consists of a dual shaft extension
                         generator, two turbines and associated oil system.

                         (A) SYNCHRONOUS GENERATOR

                         The generator is a synchronous type, air-cooled, three
                         phase machine, brushless and weather protected. It is
                         built to NEMA II specifications and rated at kW, 0.85
                         PF, 13.8 kV and 60 Hz. It is cooled by a once-through
                         air-cooling system with an inlet filter. The generator
                         and the two turbines are directly coupled.

                         (B) TURBINE

                         Each of the two OEC turbines consists of a single
                         casing, multi-stage axial unit. The turbine is directly
                         coupled to the end of the generator shaft. No
                         speed-reducing gearbox is required because the
                         properties of the organic fluids produce favorable
                         aerodynamic matching at relatively low blade and
                         rotational speeds. A double, mechanical shaft seal is
                         used to prevent leakage of the working fluid into the
                         atmosphere or lube oil.

                         (C) TURBINE AND GENERATOR OIL SYSTEM. The oil system
                         has two functions:

                     o   To supply oil to each turbine bearing for lubrication,
                         sealing and cooling, and

                     o   To supply oil to the generator bearings for
                         lubrication.

                         The oil system is designed to supply each oil consumer
                         with the proper pressure and flow, and the proper type
                         of oil. Each system is equipped with an oil pump as
                         well as oil filters, oil coolers (forced air-cooled
                         type), solenoid operated control valves and relief
                         valves. The system is

                         equipped with air operated emergency pumps and air
                         accumulator to supply the lube oil in the event of an
                         electric power failure.

                     o   Motive feed pump system including motive fluid pumps
                         and piping.

                         The feed pump is a motor-driven multi stage vertical
                         turbine centrifugal pump, which transfers the
                         condensate motive fluid from the condenser liquid
                         collector into the heat exchangers. A mechanical seal
                         separates the high-pressure motive fluid from the
                         atmosphere.

                         The pump discharge is connected to the recuperator or
                         preheater inlet through level control valve and swing
                         check valve.

                         A manual valve is installed at the suction strainer
                         inlet to allow maintenance of the strainer and the
                         pump.

                     o   Organic Motive Fluid Piping system

                         The organic motive fluid piping system consists of
                         piping assemblies, in which the condensed motive fluid
                         flow from the feed pumps through the recuperator and
                         preheater to the vaporizer, vapor motive fluid flow
                         from the vaporizer to the turbine and from the turbine
                         to the air cooled condenser and in which the condensed
                         motive fluid return from the condenser hot well to the
                         feed pumps. A motive fluid strainer is installed
                         between the hot well collector and the pump inlet.
                         Expansion joints are installed in the turbine inlet and
                         outlet pipe assemblies to reduce the force and moments
                         on the turbine nozzles. Automatic and manual control
                         valves are supplied as part of the piping system.

                     o   Purge system

                         The purge system is installed on the upper side of the
                         condenser outlet boxes. The system is designed to
                         continuously purge the OEC condenser of non-condensable
                         gases, predominantly air, that enter the OEC, mostly
                         during start-up and when the unit is not operating, and
                         to recover the working fluid.

                     o   Power and control system

EPC Galena Project

                                    PAGE A-10

                         (OEC power and control cabinets may be installed in
                         either pre-fabricated power shelters (one per each
                         unit) or inside one main building in the power plant).

                         The OEC power system contains of: (i) the generator
                         high voltage breaker, PTs and CTs; (ii) Protection
                         relays board and (iii) 480 Volt auxiliaries supply
                         board (MCC).

                         The control system is based on a programmable logic
                         controller (PLC). The OEC control incorporates a
                         turbine control backup relay (TCBU), which disconnect
                         the OEC from the bus and shut it down safely in event
                         of a PLC malfunction. The PLC and I/O units with its
                         accessories, is housed in a control board and fields
                         junction boxes.

                         The OEC control and protection system contains the
                         following items:

                         (a)  PLC: central processing unit with analog and
                         digital input and output modules, and communication
                         control units.

                         (b)  PROTECTION RELAYS to provide generator protection
                         against under/over voltage, reverse power, loss of
                         excitation, generator differential, phase over current,
                         ground fault, phase balance, over speed, etc.

                         (c)  SYNCHRONIZER, check synchronizer, voltage
                         regulator and VAR controller, and

                         (d)  OPERATION MODE SELECTOR switch and reset push
                         buttons for local operation. Same switch and push
                         buttons are duplicated by soft switch at the HMI
                         computer screen for remote operation of the OEC from a
                         local control room.

                         The control system automatically accelerates the
                         generator to synchronous speed and then synchronizes
                         the generator to the bus. After being linked with the
                         bus, the control system monitors and controls the
                         operation of the OEC. Pressures, temperatures,
                         voltages, speed, kilowatts, kilovars, currents, etc.,
                         are checked and monitored and compared with preset
                         values in memory, to detect warning or failure
                         conditions.

                         In the event of a failure within the system, the unit
                         is

                         disconnected from the bus and shut down in a
                         pre-programmed sequence. After a failure condition is
                         rectified, the generating unit can be automatically
                         started after a manual reset signal.

                     o   Electro-Pneumatic Control System

                         The electro-pneumatic control system operates the
                         control valve actuators and provides air pressure to
                         pneumatic components, either directly or through
                         solenoid-operated valves installed on the pneumatic
                         control panel. The pneumatic control panel is supplied
                         by air at a nominal pressure of 90 psi, the pressure
                         required to operate the pneumatic equipment. Pressure
                         regulation and filtration is also provided.

                         Electronic control signals for the system are provided
                         from the central unit control in the form of digital
                         (ON, OFF) or analog (4 to 20 mA). The analog signals
                         are converted by current to pressure (I/P) transducers
                         to a proportional pneumatic output signal.

                     o   Human-Machine Interface (HMI)

                         The system includes a personal computer with dedicated
                         software to enable the operator to operate the power
                         plant and monitor its functions.

                     o   Interface With Local / Remote Station Controls

                         The control system provides access to all the analog
                         and digital signals connected to the PLC through a
                         communication link. Using the communication link,
                         Company can monitor parameters inside the PLC, send the
                         OEC Stop Command from another PC with the proper
                         software. The data inside the PLC is organized in
                         blocks of accessible registers. Detailed requirements
                         for the data transfer of information are determined
                         during detailed design. This includes both
                         communication and hard-wired interface data.

                     o   Instrumentation

                         All parameters that are measured to insure proper
                         control and operation of the OEC, such as pressure,
                         temperature,

                  normal hot start procedure as described in O&M manuals, and
                  resume normal operation conditions.

            The test will be recorded as per the attached test record of
            Individual Generating Units Test.

      3.2   Performance Test

            Upon completion of the mechanical tests, the Individual Generating
            Units test and after being run at full rated load for a sufficient
            length of time to ensure thermal saturation, the Facility will be
            tested as close as possible to the Design Conditions, for a period
            of four (4) hours at full rated load to verify the Plant's capacity.
            The ambient temperature and the heat source conditions will be
            within the Design Range.

            During this test, the performance of the Plant will be monitored,
            with manual and automatic recording of readings as specified in
            Section 6.4 hereof.

4.    TEST PROTOCOLS

      The procedures for conducting the tests, including calibration data,
      instrumentation data, test records and frequency of measurement will be
      detailed in individual test protocols. The individual test protocol will
      be drafted by Contractor and submitted for review to Company at least
      forty five (45) days prior to the start of any individual test. All
      components of the test protocol, including revisions, will be approved at
      least fifteen (15) days prior to the commencement of the relevant test.
      The test protocols will be consistent with the terms of this Exhibit D.

      The test protocols shall explicitly state the industry codes and standards
      that will be used, the instrumentation required, the form of the expected
      results, the anticipated time duration of the test and the anticipated
      number of Company's operating personnel required to assist Contractor in
      the conduct of the test.

5.    REPEATING AND SUSPENSION OF TEST

      If test criteria are not met or problems or deficiencies arise during the
      conduct of the tests which require cessation thereof (including due to
      Company Default, causes attributable to other entities such as utilities
      and Force Majeure), or if Contractor opts to retest to improve test
      results, Contractor will establish the actions to be taken to bring about
      a successful completion of the tests. Such actions shall be taken by
      Contractor and the tests shall be reconducted.

      Subject to the provisions of the Contract, Contractor may repeat any of
      the tests. In

                                        3

      case one or more of the tests are repeated, the latest of the test results
      will be utilized to establish the final results of testing. Repeating one
      or more of the tests does not require repeating any of the other tests,
      unless it affects the results of tests already performed.

      Subject to the provisions of the Contract, the tests may be suspended by
      Contractor upon each occurrence or circumstance beyond the control of
      Contractor which does not reflect equipment failure, design or
      construction defects (e.g., a problem with the grid, supply of heat
      resource not in accordance with the design range, Force Majeure, etc.),
      which make operation of the tests unfeasible. The test period may resume
      after the period(s) of suspension, with the test period including
      period(s) of Facility test operation both before and after the period(s)
      of suspension, if Contractor so desires. Alternatively, at Contractor's
      discretion, the tests may be repeated from the beginning following a
      suspension.

      Adjustments to the Plant during suspension shall not impact on the
      availability of the Facility to resume the tests when the causes of
      suspension no longer exist unless Contractor elects to repeat the tests
      from the beginning.

6.    INSTRUMENTATION

      Permanent Plant instrumentation shall be utilized for measurement and data
      collection. A list of key instruments to be used during the tests will be
      specified by Contractor prior to the initiation of the test. The
      instruments will be calibrated in accordance with the standards of a
      recognized national organization such as the American Society of Testing
      and Materials (ASTM), the Instrument Society of America (ISA), etc.
