PROJECT INFORMATION ABSTRACT - The following provisions from the original ---------------------------- RFTP are specifically included in the terms of this contract. 1. Project Description ------------------- The Western Division, Naval Facilities Engineering Command (WESTNAVFACENGCOM) wishes to develop geothermal power as an alternative to conventional power sources at the Naval Weapons Center (NAVWPNCEN), China Lake, California. Preliminary investigations under the auspices of NAVWPNCEN, the U.S. Geological Survey, and the Department of Energy indicate a potential source of geothermal power in an area of NAVWPNCEN identified as the Coso Known Geothermal Resources Area (KGRA). WESTNAVFACENGCOM is issuing this Request for Technical Proposals (RFTP) in order to develop approximately 3 1/2 square miles of this potential resource for which the Navy has authority to develop. After determining the capacity, nature and reliability, of the resource through his own exploration program, the Contractor shall build, own, operate and maintain one or more geothermal power plants and necessary power lines, power transformer substations and associated equipment and facilities to deliver, initially, the full electrical energy requirements of NAVWPNCEN China Lake and subsequently other Navy activities, but not to exceed 75MW to the Navy at the designated delivery points (see Appendix "E"). The price bid under Step Two of this RFTP shall be all-inclusive for supply of power to NAVWPNCEN China Lake as more fully described in Section III. The price for power to other Navy activities will be negotiated under the Changes Clause. Delivered power at each designated delivery point must meet the total electrical load at each point and at no time shall the total cost per kilowatthour (WH) to the Navy be above 95 percent of the Ceiling Rate as defined in Appendix "F". The exploration, development, commercial operation, and maintenance of the Contractor's facilities and delivery of power must be at no capital cost to the Department of Defense. Title to the geothermal resource or electricity produced therefrom must remain in the Government except as further described for electricity in Section VI.A. The Government will provide the Contractor a real estate entry permit and will pay the Contractor his bid rate in price per KWH received by the Government, as escalated by the Coso Geothermal Index (CGI) and constrained by the Ceiling Rate (see Appendix "F") during the thirty year term of the contract. At no time during the term of the contract will the Department of Defense be obligated to pay more than 95 percent of the then established Ceiling Rate. This RFTP defines the project parameters and solicits responsive proposals from qualified offerors. A two-step RFTP is being solicited. The step-one proposals shall be limited to technical, business, environmental and other matters, and they must not contain any cost information. After evaluation for technical adequacy, acceptable offerors will then be invited in Step-Two to submit a cost proposal. The contract award will be made to the offeror submitting the lowest bid in price per kilowatthour for electric energy receive by the Government at NAVWPNCEN China Lake designated delivery point provided that the bid price is less than the Ceiling Rate as defined in Appendix "F". The Navy reserves the right to reject all bids if no bid is below the Ceiling Rate. 5 The Contractor shall explore, evaluate, and develop the geothermal resource; construct, operate and maintain a geothermal power plant; and deliver power to the Government as rapidly as possible within certain constraints, including that there be NO CAPITAL EXPENSE TO THE DEPARTMENT OF DEFENSE, that ----------------------------------------------- there be NO ADVERSE IMPACT UNACCEPTABLE TO THE NAVY ON THE MISSION OF NAVWPNCEN ---------------------------------------------------------------------- and that there be a NET COST SAVINGS TO THE GOVERNMENT. Development and ---------------------------------- extraction of geothermal by-products will require specific Navy approval and be accomplished in accordance with existing law. The Navy desires to expeditiously develop the full potential of its resource. Subsequent development and delivery of power in excess of 75 MW will be negotiated under the contract Changes Clause. The Government will consider such further development of Navy fee-acquired land up to the then existing southern California Navy loads. These Navy loads are currently served by Commercial Utility Companies under standard rate schedules. \\Modification P000011 deleted the first paragraph of Section II below and replaced it with that shown on the top of page 7.\\ [intentionally left blank] 6 \\Modification P000011 changed the first paragraph of Section II to read as follows:\\ II. CONSTRAINTS ----------- It shall be the responsibility of the Contractor to conform to and abide by all legally applicable statutes; ordinances; rules and regulations and all permit, approval, and easement requirements relating to the development of the geothermal resource at the Coso KGRA area, access to and from the general sites, and construction on and use of property under the control of NAVWPNCEN China Lake. In addition to the laws and regulations identified in Environmental Protection Plan, Section V, and the terms of this contract, the Contractor is referred to Naval Weapons Center Instructions (see Appendix "G"); the Geothermal Resources Operational Orders as published by the Geological Survey; the Geothermal Steam Act; the Geothermal Energy Research, Development and Demonstration Act; the Federal Land Planning and Management Act; the Defense Withdrawal Act of 1958 (P.L. 85-337); Title 30, the Code of Federal Regulations; and the Occupational Safety and Health Act, or any successor statutes thereto, all as from time to time amended. Unless specifically advised by the Contracting Officer to the contrary, the Contractor shall meet the legally applicable requirements of all State and Local Laws and Regulations. This list is not all inclusive and it is the sole responsibility of the Contractor to acquaint itself with all legally applicable Federal, State and local laws, regulations, and other legal constraints or requirements. Because of the nature of the NAVWPNCEN mission, the Government has placed certain constraints on geothermal operations within the boundaries of NAVWPNCEN. These constraints ensure the safe and economical development and production of those geothermal resources within the NAVWPNCEN boundary and ensure that any exploration, development, or production does not conflict with the mission of NAVWPNCEN. All on-site and other inspection performed by the Government will be at Government's cost. A. Administrative Responsibility ----------------------------- The Commander, NAVWPNCEN is the responsible agent of the Federal Government for the utilization of the land and airspace of NAVWPNCEN. As such, the Commander, NAVWPNCEN is responsible for the protection of the health and safety of all personnel, military and civilian, within the confines of NAVWPNCEN, and is responsible for the continuing preservation of the ability of NAVWPNCEN to perform its mission of air weapon research, development, test and evaluation. B. Access ------ Access to NAVWPNCEN is a privilege granted by Commander, NAVWPNCEN. Exercise of this privilege requires adherence to Navy traffic regulations, check-in/check-out procedures, radiation control measures, environmental controls, area access limitations, and electronic emission 7 controls. Access to range lands shall be on a not-to-interfere basis with Navy test schedules and shall be limited to that specific area being explored, developed or produced. Access schedules shall be established on a weekly basis with the Navy. The Public Works officer, NAVWPNCEN will have the authority to provide emergency access for reasons of geothermal safety or other drilling incidents requiring uninterrupted short term access to a specific site or geothermal operation. Access shall require that there be identified one responsible contact point for the Contractor who shall at all times know who is present on NAVWPNCEN lands, and this contact point shall be reachable at all times in event evacuation is ordered. Experience to date shows, in any given month, scheduled and unscheduled daylight downtime will not regularly exceed ten percent and scheduled and unscheduled nighttime downtime will not regularly exceed two percent. C. Security -------- Contractor personnel do not have to be U.S. Nationals, but the mission of the NAVWPNCEN is such that personnel cannot be granted access to NAVWPNCEN lands without being cleared for entry by the Navy. All non-citizen visits must be arranged through the Navy with a minimum notice of 96 hours for non-iron- curtain-bloc visitors. The latter will be considered on a case by case basis. The accessible areas and routes from these areas will be stipulated by the Navy. D. Environmental ------------- All vehicular traffic shall be limited to routes approved by the Navy. The Navy will retain the right to suspend any operation judged by the Navy to present an imminent threat to the environment. During all operations, all federal, state, and local environmental requirements shall be rigorously observed. The Navy shall have the right to impose emission standards required to protect the mission of NAVWPNCEN. \\Paragraph 2 on page 2 of P00008 provides Section II E of the contract is amended to read in full as follows: "E Sites and Routes ---------------- Power plant sites, drill pads, pipeline and power transmission routes will be selected subject to Navy approval to ensure such sites will have a minimum impact on NAVWPNCEN range operations. All site plans shall be submitted to the Navy for approval. Routes to and from work areas will be approved by the Navy."\\ F. Shelters -------- Operators and other Contractor personnel shall have the option of either evacuating NAVWPNCEN upon request or retiring to Navy approved personnel shelters during those times when NAVWPNCEN operations require personnel protection at the project site. Construction criteria for personnel shelters are included in the Technical Specifications, and installation will be totally at Contractor's expense. 8 G. Radioactive Sources ------------------- No radioactive sources shall be brought into NAVWPNCEN until appropriate Navy permits have been obtained. These permits will be issued upon the Navy verifying the license of the operator to be valid for the proposed effort, and the Navy approving a standard operating procedure for dealing with lost sources and handling damaged sources. H. Injuries and Accidents ---------------------- All disabling injuries occurring on NAVWPNCEN land will be reported within 24 hours to the Navy. The Navy will retain the right to suspend any operation judged by the Navy to present an imminent danger to people or to government property. I. Electronic Radiation -------------------- No electronic radiation will be permitted within NAVWPNCEN until a permit is obtained which certifies this emission will not interfere with the NAVWPNCEN mission. The Navy may, at times, require electronic emission silence for up to four hours. J. Plant Protection ---------------- To prevent damage, all wellheads shall be revetted as specified in the Technical Specifications, all wells shall be fitted with an approved below- ground flow limiter, all pipe lines fitted with automatic flow limiters, and all power plants equipped with a hardened control room. K. Public Release of Information ----------------------------- There shall be no public release of information or photographs concerning the aspects of this contract or other documents resulting therefrom without prior written approval of the Navy. L. Military/Government Property ---------------------------- As a result of past and ongoing NAVWPNCEN operations, the existence of unexploded ordnance and other hazardous material in the Coso KGRA is very likely. The danger that such material represents cannot be overemphasized. Therefore, all military or government property found on the land surface or embedded in the land shall be left in place. The Navy shall be informed of the presence of all hazardous or potentially hazardous ordnance or other material at once and Navy personnel will inspect and remove such material in a timely manner. 9 M. Data Exchange ------------- Data on flow, chemistry of fluids and reservoir conditions and structure shall be provided to the Navy within 90 days of the date the data is obtained by the Contractor with such data to remain proprietary to the Contractor for five years or contract termination, whichever occurs first. The Navy may use such data for independently evaluating the resource. N. Legal Jurisdiction ------------------ Law enforcement on NAVWPNCEN lands will remain the responsibility of the Navy except that the Navy may permit Inyo County deputized corporate security guards on NAVWPNCEN lands following Navy acceptance of specific Contractor security plans. O. Blowout Contingency Plan ------------------------ Prior to the commencement of any drilling into the geothermal reservoir, the Contractor shall prepare a contingency plan acceptable to the Navy for use in the event of a blowout of a geothermal well. P. Geothermal Resources Operational (GRO) Orders --------------------------------------------- The GRO Orders, as published by the United States Department of Interior, Geological Survey, Conservation Division, Office of the Area Geothermal Supervisor, and Title 30, Chapter II of the Code of Federal Regulations shall be adhered to subject to certain interpretations that are discussed in more detail under Technical Specifications, Section VI. Q. Right of Inspection ------------------- Navy shall have the right of inspection to ensure and verify compliance with these constraints. R. These constraints shall be included in all subcontracts. 10 III. PRICING, ESCALATION AND PAYMENTS -------------------------------- A. General ------- The Government will accept from the Contractor electric energy service for Navy loans listed in Appendix "E". The Government will pay Contractor on a monthly basis for delivery of such electric energy as metered at the designated delivery points. Payments will be made solely for electrical energy consumed by the Government as recorded on a watthour meter at the designated delivery points, and not for energy that is available to the Government but not actually consumed. The Government will pay the Contractor 56 mils per KW escalated by the Coso Geothermal Index (but never more than 95 percent of the Ceiling Rate defined in Appendix "F") for each KWH consumed by the Government as metered at NAVWPNCEN China Lake designated delivery point identified in paragraph A of Appendix "E". After serving NAVWPNCEN China Lake, the Contractor shall serve additional designated delivery points as his generating capacity permits at a rate to be negotiated under the Changes Clause. Once the Contractor has agreed to supply electrical energy to a delivery point, he shall be solely responsible to provide all electrical energy needs to that delivery point. It is understood that the Navy loans listed in Appendix "E" are presently being serviced by a utility company under contract to the U.S. Navy. It is agreed that the Contractor will pay for any costs of termination involved in such existing contracts, and that the sole payment by the Navy under this contract is for the price bid by the successful Contractor. Similarly, the Government will not make payment for any additional items of cost including, but not limited to, wheeling, banking, standby, emergency, backup, line transmission loss, metering loss, transformer loss, power factor, demand, termination charges, and the like. As additional generating capacity is installed, the Contractor is required to serve additional designated delivery points if technically feasible at a rate to be negotiated under the Changes Clause. B. Power Availability ------------------ Electric service shall be available at the designated delivery points which the Contractor has agreed to serve 100 percent of the time subject to force majeure. The Contractor shall use reasonable diligence to provide a regular and uninterrupted supply of service at the service locations, but shall not be liable to the Government for damages, breach of contract, or otherwise, for failure, suspension, diminution, or other variations of service occasioned by any cause beyond the control and without the fault or negligence of the Contractor. 11 C. Price Escalation ---------------- On 1 February and 1 August of each year, the contract unit price will be adjusted for the following six month period to reflect the percent change (increase or decrease) in the Coso Geothermal Index (See Appendix "C") during the previous six month period. The first escalation will occur on 1 August 1984 based on the previous six month period. D. Incremental Development of Geothermal Power Generation ------------------------------------------------------ \\Page 3, item [3] of Modification P000011 amends Section III.D.1 to read in full as follows:\\ 1. At such time as the existence of a commercial geothermal resource has been established by the Contractor, the Contractor shall proceed to design and install power generation plant(s) of sufficient capacity to produce and deliver the proposed capacity adequate to provide electrical service to at least NAVWPNCEN China Lake, but not in excess of the generating capacity for which the parties have agreed to hereunder. 2. Should the Government determine that further development of the resource beyond 75 MW is feasible and that it is in the best interest of the Department of Defense so to do, the Government may, by the Changes Clause authorize Contractor to proceed with development of the field and production of electrical power. 3. The Contractor's plan for the development of the geothermal resource shall include procedures to ensure close coordination of plant development and distribution of energy with changing Navy requirements. The Government will also closely coordinate with the Contractor on planned changes in Navy requirements. \\Page 3, item [4] of Modification P000011 adds a new Section III.E. to read in full as follows:\\ E. Expansion Beyond NAVWPNCEN -------------------------- The Government and the Contractor have determined that the entitlement provided to the Government with respect to NAVWPNCEN pursuant to Section IV.C.1 of the contract is not appropriate as Government entitlement with respect to expansion beyond the generating capacity of Unit I-1. A different method for determination of such entitlement has accordingly been negotiated and agreed to by the parties and the provisions controlling said expansion and Government's entitlement shall supersede the provisions of paragraphs A, B, C and D of Section III of the contract. 12 IV. GEOTHERMAL POWER GENERATION/ELECTRIC SERVICE SPECIFICATIONS ----------------------------------------------------------- A. Technical Provisions for Utility Service ---------------------------------------- 1. Measurement of Service ---------------------- (a) All service furnished by the Contractor at the designated delivery points shall be measured by metering equipment of standard manufacture, furnished, installed, maintained, calibrated, and read by the Contractor at his expense. In the event that any meter fails to register or registers incorrectly, the quantity of service delivered through it during that period shall be determined and an equitable adjustment based thereon shall be made in the Government's bills (for this purpose any meter which registers not more than 2 percent slow or fast shall be deemed correct). Failure to agree on any adjustment shall be a dispute concerning a question of fact within the meaning of the "Disputes" clause of this contract. (b) The Contractor shall read all meters at periodic intervals of approximately thirty days. All billings based on meter readings of less than twenty-seven days or more than thirty-two days shall be prorated accordingly. 2. Meter Test ---------- The Contractor, at his expense, shall periodically inspect and test the meters at intervals of no longer than six months. At the written request of the Contracting Officer, the Contractor shall make tests of any or all of such meters in the presence of Government representatives. The cost of such tests shall be borne by the Government if the percentage of error is found to be not more than 2 percent slow or fast. No meter shall be placed in service which on test registers in excess of 100 percent under normal operating conditions. Upon request, the Contractor will provide copies of all test data to the Government. B. General Provisions for Utility Service -------------------------------------- 1. Payment ------- (a) The Contractor shall submit invoices monthly to locations as listed on the Electric Service Specifications and payments hereunder shall be made by the designated disbursing officer for service furnished hereunder at the rate specified.

Developable Lands ----------------- Fee title to the surface and mineral rights of the land available to the Contractor for exploration and development is vested in the United States of America. This property is identified in Appendix "A" and the attached map (Appendix D"). The Navy has authority to authorize a Contractor to explore and to develop the geothermal resource for the purpose of producing electric energy. Four non-contiguous fee-owned land areas are in the Coso area. The largest contains approximately 1,920 acres; the other three contain about 640 acres, 320 acres and 40 acres. Generally excluded from development or exploration is approximately 605 acres of the 1,920 acre parcel identified in the National Register of Historic Places. This excluded area is identified in Appendices "A" and "D". The total area available to the Contractor for development (hereinafter called developable lands) is therefore about 2,315 acres, or about 3 1/2 square miles, as well as the approximate 4 square miles added to this contract as a result of this modification. The Contractor shall have the sole right to investigate, explore, develop and produce electricity from the developable lands as defined above during the term of the contract. Except as provided in this contract, no interest in steam, electricity, water, earth, gravel, rocks or minerals will be conveyed to the Contractor who explores the resource and develops the electric power. This does not preclude the Contractor's transfer of electricity as a form of payment for services rendered. Necessary quantities of these resources may be used by the Contractor at no charge subject to Navy approval and provided that: 1. The resource is incidental to the performance of the contract; and 2. The resource is obtained by the Contractor from: a. Developable lands b. The surface of NAVWPNCEN lands in the Coso area, excluding therefrom lands identified in the National Register of Historic Places, or c. In the case of water, no deeper than 1,000 feet below the surface of NAVWPNCEN lands in the Coso area, excluding therefrom any public water reserves; and 3. The resource (other than electricity) is not transported outside NAVWPNCEN boundaries; and 4. The resource (other than electricity) is not sold to anyone or transferred to a party other than a subcontractor to the Contractor; and 5. The resource is utilized for the purpose intended by this contract. 20 The electricity may be bartered, traded or sold as a means of paying for peak Navy energy requirements as well as such items as wheeling, banking, standby, emergency, backup, line transmission loss, metering loss, transformer loss, power factor, demand, termination charges, and the like. Development and extraction of geothermal by-products will require specific Navy approval and be accomplished in accordance with existing law. B. Hardening --------- The Navy may require, from time to time, personnel on the NAVWPNCEN China Lake ranges to evacuate NAVWPNCEN ranges or take shelter. Until such time as an acceptable hardened facility of sufficient size to protect all personnel is constructed, all unprotected personnel shall evacuate NAVWPNCEN ranges when so ordered. After completion of the hardened facility, personnel shall either evacuate the ranges or take shelter in the hardened facilities, whichever can be done most expeditiously. Contractor has the option to provide hardened facilities during drilling operations. C. Financial --------- All work under the contract shall be at Contractor's expense. The Contractor shall be responsible for determining the requirements and obtaining at his expense, any and all approvals, easements, or permits from governmental agencies or private parties having jurisdiction. The Contractor shall be solely responsible for any taxes, bonding, third party insurance, wheeling, banking, and all other charges associated with this contract. D. Maintenance ----------- Existing roads on or serving the area under this contract shall not be impaired by the Contractor. Road maintenance will be required based on Contractor's usage and will be the responsibility of the Contractor. E. GRO Orders ---------- All work under the contract shall be performed in accordance with the GRO Orders, except where this contract specifies differently. The GRO Orders refer to the Geothermal Resources Operational Orders as published by the United States Department of Interior, Geological Survey, Conservation Division, Office of the Area Geothermal Supervisor. The latest draft of GRO Order 5 shall apply, until the final version is published. The following substitutions of terminology, however, will apply to the work done under this contract: the terms "Area Geothermal Supervisor", "Supervisor", "U.S. Geological Survey Geothermal District Office", "Secretary" or "Director" are to mean the Navy; "lessee" or "operator" are to mean the Contractor; and "lease" is to mean the Entry Permit. The GRO Orders make reference to Chapter 11 of Title 30, the Code of Federal Regulations. Where applicable, the modifications to the language and intent of the original regulations, as noted above, shall apply to this contract. Plans and reporting requirements 21 identified in this contract shall meet the Contractor's obligation, provided that where data is requested by GRO Orders or the regulations and not in this contract, such data shall be provided by the Contractor. F. Protection and Closing of Wells ------------------------------- Geothermal wells shall be provided with a flow limiter below the surface of the ground. In addition, the wellheads shall be revetted. Earth berms or, at some locations, a culvert arch (open at both ends) covered with several feet of dirt and rock rubble are typical of the required revetments. If work under this contract is terminated at the direction of either party, the following conditions of completed or unfinished wells or borings will apply: 1. Any casing or plugs set into the well shall remain in place, and title to such items will automatically pass to the Government upon the decision to terminate. 2. All non-productive wells will be plugged and abandoned in accordance with GRO Order No. 3 prior to final abandonment of the project. 3. Any producing well will be fitted with a valving or regulating mechanism to allow either a complete shutdown of the well or withdrawal of the geothermal resource in a regulated and controlled manner as specified in GRO Order No. 2, paragraph 5.B. G. Contractual Phases of Work -------------------------- The exploration and development of the resource and operation of the power plant is divided into five phases as follows: Field Investigation and Research (Phase A), Field Exploration (Drilling) (Phase B), Field Development (Power Plant Construction) (Phase C), Power Production and Field Operation (Phase D), and Field Closure (Phase E). H. Termination During Exploration ------------------------------ The Contractor may elect to terminate work on the project during the first two phases. Such termination is to be at Contractor's expense including costs for site restoration and equipment removal. In the event that the Contractor elects to terminate the work, the Navy will acquire the rights (including right to further distribution without incurring obligation) to all data developed, and all the Contractor's rights and interest in the project are terminated. Navy may proceed with such development as Navy may determine to be in the best interest of the Government without any continuing obligation to Contractor. I. Capacity -------- Throughout this contract, capacities refer to electric paver in megawatts (MW) as delivered to the designated delivery points. The initial minimum acceptable capacity is the full electrical energy requirements of NAVWPNCEN China Lake. The maximum acceptable capacity (at any time during this contract term unless so modified under the Changes Clause) is 75 MW. 22 The Navy desires to develop the full potential of its resource. The Contractor, therefore, should identify how and when he plans to develop from the initial capacity to 75 MW. Subsequent capacity beyond the first 75 MW will be negotiated under the Changes Clause. Paragraph 7 on page 10 of 10 to P00008 provides Section VI.J. of the Contract is amended to read as follows: "J. Schedule. The schedule for completion of work to be performed with -------- respect to each geothermal power plant under this Contract is set forth in the appropriate portion of Section IV.C or IV.D hereof. Each such schedule is intended to specify maximum periods of time for the key elements of work unless unforeseen delays (including and not limited to regulatory agency approvals) are encountered which cannot be overcome by the parties exercising due diligence. Each such schedule represents the maximum times the Navy considers appropriate, but the Navy is desirous of completing each phase in the least time possible." \\Page 6, item [8] of Modification P000011 amended VI.J to add the following sentence:\\ Unit I-2 and Unit I-3 shall be complete and shall be on-line on or before June 3, 1989. \\Page 5, item [3] of Modification P000012 amends Section VI.J to add the following:\\ Unit II-1, Unit II-2 and Unit II-3 shall be complete and shall be on-line on or before January 31, 1990. 23 K. Recording Requirements ---------------------- Status reports will be provided the Navy annually during the term of the contract. Well logs and other technical data shall be provided the Navy no later than 90 days (or less if so identified in the applicable version of GRO Order No. 5) after data is obtained by the Contractor. Other technical data may include any or all data identified in GRO Order No. 5. The Navy will have the right to data obtained by the Contractor during the term of the contract from geophysical investigations, exploratory wells, development wells, and reinjection wells. Such data to be treated as proprietary to the Navy and Contractor for five years or contract termination whichever occurs first. The data will be for Navy use in conducting an independent evaluation of the resource. L. Field Investigation and Research (Phase A) ------------------------------------------ A substantial body of research data has already been compiled regarding the potential geothermal resource at Coso. The Contractor will use this information, plus any additional data that is available or obtained by the Contractor, to select exploratory drill site locations. It is anticipated that this phase of the operation will be limited, both in terms of time and the amount of additional field data (such as additional temperature gradient holes) that will be required. At the completion of the Field Investigation and Research, an analysis and evaluation of the results of these investigations will be conducted by the Contractor and a determination made as to the feasibility of proceeding with an exploratory drilling program. At that time, the Contractor will update as necessary his submitted plan for Field Exploration (Drilling) phase. The plan shall identify, at a minimum, the drilling company and contract; size, depth, and the location of exploratory wells; the schedule for obtaining necessary approvals, if any, from regulatory agencies; waste disposal methods; and methods of well testing. 23a M. Field Exploration (Drilling (Phase B) ------------------------------------- During the Field Exploration (Drilling) phase, the Contractor shall drill deep geothermal wells as necessary to further evaluate, identify and locate the geothermal reservoir. Flow testing of the wells shall be performed as required. Once the flow testing is completed, an exploratory well can be shut-in if it is not commercially productive, or it can be left on a slow bleed to be converted to a production well at a later date if the flow is adequate. At the completion of Field Exploration (Drilling), an analysis and evaluation of the results of these investigations will be conducted by the Contractor at his expense and a determination made as to the practicality of proceeding with a geothermal electric power plant. At that time, the Contractor shall prepare a formal report evaluating the reservoir and determining the feasibility of producing electric power therefrom. This report shall utilize data developed from the drilling and testing of exploratory wells. Contractor will evaluate the resource and the economic factors affecting geothermal development, including construction and operation of electric power generating facilities. Reliability of the resource will be established by the Contractor. Also at the completion of Field Exploration (Drilling), the Contractor shall update his submitted plans for Field Development (Power Plant Construction) phase and Power Production and Field Operation phase to reflect results of the exploratory phases. Specific production well, reinjection well, personnel shelter, power plant, and transmission line siting data shall be submitted to the Navy for approval at this time. N. Field Development (Power Plant Construction) (Phase C) ------------------------------------------------------ The Contractor shall design and construct a power plant and related facilities and drill production and reinjection wells in accordance with his plans and schedules at his expense. Construction activities during this phase include drill sites and wells; power generating plant and associated support facilities; geothermal steam or fluid pipelines; transmission lines; and access roads to drill sites, power plants, and along the transmission lines and pipelines. The personnel shelters, if any, and the power plant control room(s) shall be hardened. The control room(s) may serve as the personnel shelter if it is of sufficient size. Sufficient hardened space shall be provided to shelter the minimum number of personnel, including visitors and drill crews, required to remain on site during the operational phase. The hardened areas shall be constructed to be equivalent to two feet of reinforced concrete (compression strength of 3,000 psi in 28 days) covered with five feet of earth and two courses of fresh granite rubble 18 to 24 inches thick. The Navy must review and approve the final design of the hardened structure(s). The power plant shall be restricted in size to provide the required capacity of Subsection I above. The Contractor was obligated to identify the initial size in his proposal, and the power plant shall be designed to provide that power at state-of-the-art availability. The Contractor shall interconnect with a commercial utility. The interconnection point shall be located on 24 NAVWPNCEN China Lake property and shall not be less than twenty feet nor more than two hundred feet easterly from the western boundary of Section 16, Township 22 South, Range 38 East, Mount Diablo Base Line and Meridian. \\Paragraph 8 on page 10 of 10 P00008 has added the following insert to Section VI.N "or SCE Inyokern substation SE Corner Section 20, Township 26 South, Range 39 East Mount Diablo Base Line and Meridian."\\ The Contractor shall install at the interconnection point and maintain a watthour demand meter meeting Navy specifications recording the total electrical power and energy transmitted off Navy property. Data shall be provided to Navy monthly on the power and energy transmitted off Navy property. Production wells shall be drilled and a waste fluid disposal system established. Contractor shall identify, at a minimum, size, depth, and location of wells; the schedule for obtaining the necessary approvals, if any, from regulatory agencies; waste disposal methods; and methods of well testing. The Contractor shall obtain required approvals, easements, and permits, if any, and construct the power plant on property made available by the Government. The Contractor, at his expense, shall construct the wellheads; pipelines; generating plant and its associated controls; electric power lines; and switching, transformer, motoring, and other equipment associated with the electric interconnection. The Contractor shall install adequate equipment to ensure that reverse electrical flow cannot possibly go through the circuit. Contractor's electricity needs (for start-up, for example) if supplied by a commercial utility shall be separately metered. In the annual status reports, as a minimum, and six months prior to the power plant becoming operational, the Contractor shall advise the Navy in writing of any modifications to his plan for his power plant design. If any modification has impact on the capacity of the power plant or power availability or the location of the designated delivery points or the characteristics of the electricity to be delivered to the Navy, the Contractor shall advise the Navy in writing within seven days of the time the Contractor is aware of the requirement for the modification, and the modification shall be subject to Navy approval. O. Power Production and Field Operation (Phase D) ---------------------------------------------- The Contractor shall update his submitted plan for Power Production and Field Operation annually. The updated plan shall include items such as schedules of preventive maintenance, drilling of new production wells, contracts for drilling, contracts for the operation of the power plant, and staffing. The Contractor shall operate and maintain the power plant and related facilities and continue field development to 75 MW in accordance with his plans and schedules at his expense. Contractor shall be solely responsible for delivery of all electrical requirements for servicing needs at the designated delivery point(s) he has agreed to serve. Delivery of the electric energy is to be to the designated delivery point(s) and in conformance with standard utility industry practice. Contractor will be responsible for continued operation of the geothermal field, including but not limited to well maintenance, drilling of supplemental wells, and maintenance of power plant and related facilities. 25 P. Field Closure (Phase E) ----------------------- During Field Closure, at the option of the Government if desired, the facilities shall be removed, wells abandoned and capped as appropriate, and Government premises restored to their original condition, ordinary wear and tear excepted, by the Contractor at his expense within a reasonable time after termination or expiration of the contract. 26 VII. GENERAL PROVISIONS ------------------ The General Provisions are contained in Appendix I. 27 VIII.SPECIAL PROVISIONS ------------------ 1. TERMINATION BY CONTRACTOR ------------------------- The Contractor may elect to terminate work on the project during the exploratory phases of work (Phase A and B) up to the time the Contractor submits his final report evaluating the geothermal resource by giving 90 days written notice to Navy.

In no event shall Contractor liability hereunder cover any costs incurred more than one year from the effective data of such termination. 2. TERMINATION BY GOVERNMENT ------------------------- The Government at any time during the term of this contract shall have the right to terminate this contract by giving six months prior written notice for reasons of national security, national defense preparedness, national emergency, or for any reasons the Contracting Officer shall determine that such termination is in the best interest of the Government. The Government shall pay Contractor the price for the unamortized portion of the exploratory investment (Phase A and B) and for the Contractor's investment in his installed power plant facilities (Phase C). (a) The Contractor shall submit his termination claim to the Contracting Officer promptly after receipt of a Notice of Termination, but in no event later chan one year from the effective date thereof, unless one or more extensions in writing are granted by the Contracting Officer upon written request of the Contractor within such one year period or authorized extension thereof. Upon failure of the Contractor to submit his termination claim within the time allowed, the Contracting Officer may determine, on the basis of information available to him, the amount, if any, due to the Contractor by reason of termination and shall thereupon pay to the Contractor the amount so determined. (b) Any disputes as to questions of fact which may arise hereunder shall be subject to the "Disputes" clause of this contract. \\Modification P000010 deleted Section VIII.2.(c) below and replaced it with the paragraph beginning near the top of page 29a hereof.\\ [intentionally left blank] 29 [intentionally left blank] \\Section VIII.2.(c) above which had been amended by P000010 has been deleted and replaced with a new Section VIII.2.(c) (page 5, item [4] of Modification P000012) to read in full as follows:\\ (c) Ceiling amount for Units I-1, I-2, and I-3: So long as the parties have agreed on a delivered price and a delivery schedule for the Contractor to provide electric power service only to NAVWPNCEN, the Governments's liability to the Contractor pursuant to this clause shall not exceed $67,500,000. This ceiling amount is derived by multiplying 25 megawatts by $2,700,00 per megawatt. When and as the parties agree on a delivered price and a delivery schedule for the Contractor to provide electric power service to designated delivery points in addition to NAVWPNCEN, the foregoing $67,500,000 ceiling shall be increased by an amount equal to the average peak load (expressed in megawatts) of these additional designated delivery points during the prior twelve months multiplied by $2,500,000 per megawatt until the average peak load of the designated delivery points for which the parties have agreed on a delivered price and a delivery schedule (including NAVWPNCEN) totals 50 megawatts. Thereafter, until the average peak load of the designated delivery points for which the parties have agreed on a delivered price and a delivery schedule (including NAVWPNCEN) totals 75 megawatts, the multiplier shall be $1,400,000 per megawatt. Thus, at the time that the parties agree on a delivered price and a delivery schedule for designated delivery points (including NAVWPNCEN) with an average peak load of 75 megawatts, the ceiling amount shall be $165,000,000. 29a \\Page 5, item [5] of Modification P000012 added a new Section VIII.2.(d) to read in full as follows:\\ (d) Ceiling amount for Units II-1, II-2, and II-3: So long as the parties have agreed on a delivered price and a delivery schedule for the Contractor to provide additional electric power beyond that covered under paragraph VIII.2.(c) above, the ceiling amount shall be derived as follows: for the first additional 25 megawatts of installed nameplate capacity, the amount due to Contractor hereunder shall not exceed $67,500,000. This ceiling amount is derived by multiplying 25 megawatts by $2,700,00 per megawatt. This ceiling amount shall be increased by $2,500,000 per megawatt for each additional megawatt of nameplate capacity between 25 megawatts and 50 megawatts and shall be increased by $2,300,000 per megawatt for each additional megawatt of nameplate capacity between 50 megawatts and 75 megawatts. Thus at the time the total additional nameplate capacity for Units II-1, II-2, and II-3 totals 75 megawatts, the ceiling amount under this Section VIII.2.(d) shall be $187,500,000. 29b 3. Force Majeure ------------- Notwithstanding anything to the contrary in this contract, if the Contractor shall fail to perform any obligation (except pecuniary obligation) hereby imposed upon it, and such failure shall be caused or materially contributed to by act of God; a public enemy; sabotage; strikes; lockouts; riots; rebellions; injunctions or interference through legal proceedings; Municipal, State, or Federal laws or regulations; breakage or accident to the resource production facilities or generating plant and related equipment, wells, machinery, equipment or lines of pipe; washouts; earthquakes; storms; freezing of lines; the availability of equipment, material or labor on the open market; or any cause or causes of whatsoever nature (whether like or unlike those herein enumerated) beyond Contractor's reasonable repairs to or reconditioning the generating plant and related equipment, wells, machinery, equipment or lines of pipe, such failure shall not be deemed to be a violation of the obligations of the Contractor hereunder. Contractor shall, however, use reasonable diligence to put itself again in a position to carry out its obligations hereunder. Contractor agrees that it shall maintain a full stock of spare parts to accomplish foreseeable repairs on the facilities. Failure of Contractor to maintain such stock of spare parts shall not be excused by this provision. 4. Default (1969 AUG) 7-302.9 ------- (a) The Government may, subject to the provisions of paragraph (c) below, by written notice of default to the Contractor, terminate the whole or any part of this contract in any one of the following circumstances: (i) if the Contractor fails to make delivery of the supplies or to perform the services within the time specified herein or any extension thereof; or (ii) if the Contractor fails to perform any of the other provisions of this contract, or so fails to make progress as to endanger performance of this contract in accordance with its terms, and in either of these two circumstances does not cure such failure within a period of 60 days (or such longer period as the Contracting Officer may authorize in writing) after receipt of notice from the Contracting Officer specifying such failure. (b) In the event the Government terminates this contract in whole or in part as provided in paragraph (a) of this clause, the Government may procure, upon such terms and in such manner as the Contracting Officer may deem appropriate, supplies or services similar to those so terminated, and the Contractor shall be liable to the Government for any excess costs for such similar supplies or services; provided, that the Contractor shall continue the performance of this contract to the extent not terminated under the provisions of this clause. 30 (c) Except with respect to defaults of subcontractors, the Contractor shall not be liable for any excess Costs if the failure to perform the contract arises out of causes beyond the control and without the fault or negligence of the Contractor. Such causes may include, but are not restricted to, acts of God or of the public enemy, acts of the Government in either its sovereign or contractual capacity, fires, floods, epidemics, quarantine restrictions, strikes, freight embargoes, and unusually severe weather; but in every case the failure to perform must be beyond the control and without the fault or negligence of the Contractor. If the failure to perform is caused by the default of a subcontractor, and if such default arises out of causes beyond the control of both the Contractor and subcontractor, and without the fault or negligence of either of them, the Contractor shall not be liable for any excess costs for failure to perform, unless the supplies or services to be furnished by the subcontractor were obtainable from other sources in sufficient time to permit the Contractor to meet the required delivery schedule. (d) If this contract is terminated as provided in paragraph (a) of this clause, the Government, in addition to any other rights provided in this clause, may require the Contractor to transfer title and deliver to the Government, in the manner and to the extent directed by the Contracting Officer, (i) any completed supplies, and (ii) such partially completed supplies and materials, parts, tools, dies, jigs, fixtures, plans, drawings, information, and contract rights (hereinafter called "manufacturing materials") as the Contractor has specifically produced or specifically acquired for the performance of such part of this contract as has been terminated; and the Contractor shall, upon direction of the Contracting Officer, protect and perserve property in the possession of the Contractor in which the Government has an interest. Payment for completed supplies delivered to and accepted by the Government shall be at the contract price. Payment for manufacturing materials delivered to and accepted by the Government and for the protection and preservation of property shall be in an amount agreed upon by the Contractor and Contracting Officer; failure to agree to such amount shall be a dispute concerning a question of fact within the meaning of the clause of this contract entitled "Disputes". The Government may withhold from amounts otherwise due the Contractor for such completed supplies or manufacturing materials such sum as the Contracting Officer determines to be necessary to protect the Government against loss because of outstanding liens or claims of former lien holders. (e) If, after notice of termination of this contract under the provisions of this clause, it is determined for any reason that the Contractor was not in default under the provisions of this clause, or that the default was excusable under the provisions of this clause, the rights and obligations of the parties shall, if the contract contains a clause providing for termination for convenience of the Government, be the same as if the notice of termination had been issued pursuant to such clause. If, after notice of termination of this contract under the provisions of this clause, it is determined for any reason that the Contractor was not in default under the provisions of this clause, and if this contract does not contain a clause providing for termination for convenience of the Government, the contract shall be equitably adjusted to compensate for such termination and the contract modified accordingly; failure to agree to any such adjustment shall be a dispute concerning a question of fact within the meaning of the clause of this contract entitled "Disputes". 31 (f) The rights and remedies of the Government provided in this clause shall not be exclusive and are in addition to any other rights and remedies provided by law or under this contract. (g) As used in paragraph (c) of this clause, the terms "subcontractor" and "subcontractors" mean subcontractor(s) at any tier. 7-302.9 5. Liquidated Damages ------------------ A. Notwithstanding anything to the contrary in paragraph 4, Section VIII herein, the Contractor shall remain liable to the Navy for any excess procurement costs for electrical power obtained by the Navy to make up the amount of electrical power which should have been provided by the Contractor for whatever period (not to exceed one year) the Navy requires with the exercise of reasonable diligence to reestablish electric service by a public utility. Thereafter the Navy shall forgo its rights to excess reprocurement costs and to any other rights or remedies arising from the default if the Contractor, promptly following the effective date of default termination, provides the Navy an amount equal to $56,000 times the average load during the prior twelve months (expressed in megawatts) of the designated delivery point (points) for which the Contractor and the Government have agreed to a delivered price and delivery schedule to supply electric power service and which is (are) terminated for default. B. At any time during the term of this contract, Navy shall have the option to consider, as an alternative remedy to termination, allowing any financing institution which has an interest in Contractor's facilities to cure Contractor's default. Should Navy elect this remedy, Contractor shall promptly assign all of its rights to said financial institution or its designee, which assignment shall require specific prior written approval by Navy. 6. Standards of Conduct -------------------- The Contractor shall maintain during the term of the contract a Standards of Conduct Program to ensure that the highest standards of ethical conduct are adhered to by representatives of the Contractor in dealing with the Navy. Upon request the Navy shall be provided access to the Plan and the reports under the Plan submitted by the Compliance Officer to the Government Relations Committee of the Contractor. 7. Release ------- The revisions in contract price and schedule established by this modification take into account all changes (constructive, written, or oral) to this contract as of the data of this modification and constitute the full and complete equitable adjustment to which the Contractor and the Government are entitled for said changes. The equitable adjustment provided herein takes into account all claims arising out of or relating to this contract as of the date of this modification, including but not limited to all delays, disruptions, dislocations, accelerations, interest costs, lost business opportunities, financing, legal and accounting expenses, bid and proposal costs, inefficiencies in performance and additional costs of whatever nature, 32 known or unknown, arising from or relating to this contract as of the date of this modification and to the changes effected by this modification. This modification also settles, and constitutes an accord and satisfaction with respect to, any claims by either party, whether or not asserted, that the contract was breached, or subject to termination for any reason, as a result of events arising prior or relating to this contract as of the date of this modification. 33 IN WITNESS WHEREOF, the parties hereto have executed this contract as of 19 October 1983.

The Contract is hereby modified as follows: [1] A new Section I.D.3, is added to the Contract to read in full as follows: "3. It is understood and agreed that the revocation of said permit shall constitute a termination by the Government within the meaning of Section VIII.2. of the Contract. Further, if Government's limitation or restriction of said permit is imposed in such a manner as to prevent the Contractor, its subcontractors, or its assigns from exercising their rights as contemplated in this Contract, then Government shall provide the appropriate monetary compensation for lost revenues within the dollar guidelines of said Section VIII.2." [2] Section II E of the contract is amended to read in full as follows: "E Sites and Routes ---------------- Power plant sites, drill pads, pipeline and power transmission routes will be selected subject to Navy approval to ensure such sites will have a minimum impact on NAVWPNCEN range operations. All site plans shall be submitted to the Navy for approval. Routes to and from work areas will be approved by the Navy." [3] To section IV.B2(c) a new subparagraph 4 is added as follows: "4. It is understood and agreed that the price (the "NAVWPNCEN Price") established, adjusted and limited in accordance with Section III.A. and IV.B2(c)(1) of the Contract for NAVWPNCEN Power (as defined at Section IV.C.3(d)(1) hereof) is not subject to change, whether upon or as part of the negotiation of prices under the Changes Clause hereof for electrical energy delivered to designated delivery points ('DDP'), in addition to that point for NAVWPNCEN ('NAVWPNCEN DDP,' as defined in Section VI.C.3(a) hereof), or otherwise, without the written consent of the Initial Consortium, described in Section IV.C.2(a) hereof." [4] Section IV.C of the Contract is deleted and a new Section IV.C is added to read in full: "C. Provisions Governing Service to NAVWPNCEN ----------------------------------------- 1. In General. The Contractor is prepared to proceed with the Phase C ---------- construction of a geothermal power plant designed to serve NAVWPNCEN. Said work will be performed pursuant to agreements by and between the Contract or and an 'Initial Consortium' (as herein defined). In order to arrange financing and assistance for said plant the following will take place: Modification P00008 Contract N62474-79-C-5382 Page 2 of 10 R&M-3 (a) The Contractor will assign to the Initial Consortium certain rights which Contractor has been granted under the Contact (subject to the Contractor's right to reacquire the same). Such assignment shall be effected by an 'Assignment and Consent' to be executed by and between Contractor and the Initial Consortium in a form approved and agreed to by the Government (hereafter the same is referred to as the "Initial Plant Assignment"). (b) Pursuant to appropriate documentation, the Initial Consortium intends to further assign certain rights and interests under the Contract and in the Initial Plant and Initial Project (both defined herein) to a third party which may be a lender ('Lender') or a lessor ('Lessor'). In this regard, it is intended that if the financing is to be provided through a lease, then the Lessor will transfer to the Initial Consortium a leasehold interest (the 'Lease') in the Initial Plant with full authority to operate the Initial Project for a term of approximately 15 years, plus extensions, if any. Upon the termination of said Lease, the rights in the Initial Plant/Project would revert to the Lessor and its successors and assigns. The Initial Consortium, the Lender, the Lessor and their respective successors and assigns are sometimes referred to herein individually as the 'Financing Party' and collectively as the 'Financing Parties'. 2. Definitions. Unless the context otherwise clearly requires, each of the following terms, when used in this Contract or in any appendix, exhibit or attachment thereto with initial capitals, shall have the meaning set forth for such term below: (a) 'Initial Consortium' means a joint venture or other business ------------------ combination, identified in the Initial Plant assignment which includes one or more engineering and construction companies and/or one or more equipment suppliers for the Initial Plant. (b) 'Initial Plant' means Unit 1 of the geothermal power plant and its ------------- ------ associated facilities as constructed by the Initial Consortium, (including and not limited to surface steam gathering system, brine disposal, system, power transmission facilities, substation, interconnection facilities and other facilities and equipment necessary to generate, sell and deliver power from such plant); but excludes all geothermal resource and wells. (c) 'Initial Project' means all elements of permitting, licensing, --------------- designing, constructing, erecting, financing, owning, operating, leasing, and maintaining the Initial Plant, and of generating, selling and delivering power therefrom, and receiving, utilizing and disbursing the revenues generated thereby; but excludes all elements of producing and bringing to the surface the geothermal resources. Modification P00008 Contract N62474-79-C-5382 Page 3 of 10 R&M-4 3. Contractor's Delivery of Electric Service for NAVWPNCEN. The Contractor's ------------------------------------------------------- obligations under the contract with respect to the 'NAVWPNCEN DDP' (defined herein) shall be satisfied by performance under coordinated contracts as follows: (a) Government's Existing NAVWPNCEN/SCE Contract Continues. The NAVWPNCEN ------------------------------------------------------ DDP is the present point of delivery under contract with Southern California Edison Company ('SCE') N62474-70-C-1201, Item 1054 ('NAVWPNCEN/SCE Contract'). Present service by SCE to the NAVWPNCEN DDP shall remain in place after the Initial Service Date (as defined herein), uninterupted, under the SCE/NAVWPNCEN Contract and shall be deemed to be full utility service by the Contractor so long as the Contractor complies with the provisions of this Section IV.C.3. If SCE fails to provide service to NAVWPNCEN DDP under the SCE/NAVWPNCEN Contract, the Contractor, the Initial Project, and the Financing Parties shall not be responsible for such failure. (b) Initial Plant Output and The PURPA Contract. Subject to the ------------------------------------------- Government's rights and powers as otherwise provided therein, the Initial Plant is authorized at all times to be operated at full capacity. All power from the Initial Plant shall be sold by Contractor or its assigns to SCE pursuant to an appropriate contract (the 'PURPA Contract'). All payments from the PURPA Contract shall be paid to and belong to the Contractor or its assigns and they are authorized to apply the same to pay SCE for NAVWPNCEN Power, to operate and maintain the Initial Plant, to service debt, to realize a recovery of and return on their capital expenditures, to operate and maintain the geothermal resource, wells, and related facilities for the Initial Project, and for other purposes. (c) Initial Service Date. The date of the commencement of service pursuant -------------------- to the Contract (herein the 'Initial Service Date') shall occur upon the earlier of (a) a date stipulated by written notice to the Government by the Initial Consortium, or (b) 1 February 1987, as such date may be hereby or hereafter modified, taking into account all applicable extensions or excusable delays pursuant to the Contract. (d) Payment for NAVWPNCEN Power (Including Conserved Power). Contractor ------------------------------------------------------- shall pay for (or shall discharge all payments due from the government to SCE for) NAVWPNCEN Power delivered from and after the Initial Service Date through the term of the Contract. Said payment or discharge shall be made subject to the following terms and conditions: Modification P00008 Contract N62474-79-C-5382 Page 4 of 10 R&M-5 (1) NAVWPNCEN Power is defined to be the amount of electrical energy equal to (A) the lesser of (i) 100,000 MWH per year adjusted cumulatively from 1 January 1986 by a 3% per year load growth factor and properly adjusted by a fraction (e.g. 30/365 for a 30 day billing period) to reflect the portion of a year covered by the billing period in question or (ii) the actual amount of energy delivered by SCE to the NAVWPNCEN DDP pursuant to the SCE/NAVWPNCEN Contract during the billing period in question, reduced by (B) the amount by which the net output of the Initial Plant delivered to SCE under the PURPA Contract for the billing period in question is less than the amount computed under Clause (A) of this Subparagraph(1) as a result of a Force Majeure event or other limiting provision of the Contract (including but not limited to Sections III.B, VIII.3, and VIII.4 of the Contract). Events which are defined as Force Majeure events herein shall constitute Force Majeure in connection wth any inability of Contractor or the Financing Parties to make delivery to SCE under the PURPA Contract. (2) Such payment or discharge shall constitute timely delivery of supplies and performance of services by Contractor within the meaning of the Contract, as hereby modified, and in particular within the meaning of Section VIII.4(a) thereof. (3) Such payments or discharge shall be on behalf of Government against its SCE bills under the SCE/NAVWPNCEN Contract. (4) If, for a given year, the amount of electrical energy for which the Government is billed by SCE falls short of an amount computed according to Section IV.C.3(d)(1)(A)(i) and reduced according to Section IV.C.3(d)(1)(B) (such shortfalls here called "Conserved Power"), the Government shall be entitled to a credit equal to the difference between (A) the price that the Contractor would have paid to SCE for the Conserved Power had it been used and (B) the price that the Government would have paid to the Contractor for the conserved power had it been used. Such credit shall be determined in accordance with the procedures set forth in Section IV.C.3(g)(8) hereof. (e) Service From Initial Project. Neither the Initial Project nor any ---------------------------- financing Party for the Initial Project shall be obligated to or liable to the Government to provide or pay for (or to compensate the Government for any failure to provide or pay for) any electrical service to Government in excess of NAVWPNCEN Power, or any electric service from Contractor or otherwise delivered to or metered at any DDP other than the NAVWPNCEN DDP. Modification P00008 Contract N62474-79-C-5382 Page 5 of 10 R&M-6 (f) Government's Right to Pay NAVWPNCEN/SCE Contract. If any SCE invoice for ------------------------------------------------ NAVWPNCEN Power has not been paid within sixty (60) days following its date, the Government, at is option, may pay such invoice and seek reimbursement for the amount thereof (including any interest and penalties due to SCE with respect to late payment) pursuant to the Contract. In the event of repeated or extended failure to pay, the Contractor shall provide a detailed report of the cause and proposed cure therefor. If such report or performance thereunder is not reasonably satisfactory to the government, the Government shall have grounds for termination under Section VIII.4 hereof. (g) Government's Payment of Contract Price to Contractor or Its Assigns. ------------------------------------------------------------------- The Government shall pay to the Contractor or its assignee an amount equal to the NAVWPNCEN Price times the NAVWPNCEN Power for each Billing Period (as herein defined) from and after the Initial Service Date, subject to the following terms and conditions: (1) The NAVWPNCEN Price has a base rate of 56 mills per KWh which is subject to adjustment after August 1, 1984, as provided in the Contract. (2) In no case shall the NAVWPNCEN Price for NAVWPNCEN Power exceed 95% of the applicable Ceiling Rate for the same (as defined in Appendix F to the Contract). (3) Each Billing Period shall have the same frequency and duration as each billing period of the SCE/NAVWPNCEN Contract. (4) Proof of payment to SCE for NAVWPNCEN Power shall be required as a condition precedent to the obligation of the Government to pay Contractor for the corresponding amount of NAVWPNCEN Power pursuant to the Contract. Full payment to Contractor or its assignee shall be made promptly upon such proof. (5) The service provided under the SCE/NAVWPNCEN Contract will be measured by the metering procedures presently followed under that contract. The Government shall provide the Contractor the results of such measurements and such other information the Contractor reasonably requires to compute payments for NAVWPNCEN Power. Contractor shall be allowed (at its own cost) to install its own meter and procedure to monitor the service and bills received by Government from SCE under the SCE/NAVWPNCEN Contract. (6) The Government's obligation to pay for NAVWPNCEN Power shall not be conditioned upon operation of the Initial Plant. Modification P00008 Contract N62474-79-C-5382 Page 6 of 10 R&M-7 (7) The invoice for NAVWPNCEN Power shall be submitted to Naval Weapons center, China Lake, California, 93555. The billing period will correspond to the referrable SCE billing period under the SCE/NAVWPNCEN Contract. Payment of each such invoice shall be made by the Disbursing Officer, Code 0862, Naval Weapons Center, China Lake, California, 93555, as directed by the Contractor or its assignee under the Initial Plant Assignment. (8) In the first calendar quarter of each year the Government and the Contractor shall audit the invoices, payments, and power output and consumption figures for the prior calendar year, reconcile all differences between them, and close the books for that year for all purposes hereunder. The Government shall be credited on the last day of such quarter with an amount for the prior year computed in accordance with Section IV.C.3(d)(4) hereof. 4. Restriction on Assignment. It is prohibited for the Contractor, its ------------------------- assigns, or their subassigns to assign any right under the Contract to or for the benefit of (a) any individual who is a national of, or any entity which is owned or effectively controlled by any government or governmental agency of or national or nationals of, any country which may from time to time be listed in country Group S, Y or Z of Supplement No. 1 to Part 370 of the Code of Federal Regulations, or any regulations which are hereafter promulgated in substitution therefor or replacement thereof, as from time to time in effect, or (b) any individual or entity to whom any such assignment is then prohibited pursuant to any other law or regulation of the United States. 5. Quiet Enjoyment. Without prejudice to the Government's rights and --------------- remedies against the Contractor, in order to provide security to the Financing Parties for their respective rights and interests in the Initial Plant and the Initial Project, and in order to permit the financing of the Initial Plant and the Initial Project in accordance with the Contract, (any other provision of this Contract notwithstanding) it is understood and agreed for the benefit of the Contractor and each Financing Party as follows: (a) So long as no default shall have occurred and be continuing, and shall be uncured (either by Contractor or the financing Parties), pursuant to the Contract in direct connection with the Initial Project, or arising from any failure to provide or pay for NAVWPNCEN Power (as limited in sections IV.C.3(d) and IV.C.3(e) hereof), the possession and enjoyment by the contractor and each Financing Party of any rights assigned to it as authorized hereby or by the Initial Plant Assignment shall be without hindrance, ejection, molestation or interruption by reason of the action, inaction, or default of Contractor or any other person or entity. Modification P00008 Contract N62474-79-C-5382 Page 7 of 10 R&M-8 (b) If the Contractor should fail to perform or comply with any of its obligations pursuant to the Contract the failure to perform or comply with which might have any material, adverse affect on any Financing Party or the Initial Project, then any Financing Party may, but shall not be obligated to, itself perform or comply with such obligations and charge the reasonable costs of such performance or compliance to the Contractor. (c) The Financing Parties, or any of them, may exercise such rights, powers and privileges of the Contractor pursuant to the Contract to supply the geothermal resource or reinjection necessary to operate the Initial Plant at full capacity as they may acquire by virtue of their assignment of rights referred to in the Initial Plant Assignment. 6. General Description of the Initial Plant. The Initial Plant will be ----------------------------------------- designed, manufactured and installed by the Initial Consortium to include a turbine which has two entries, one for high pressure steam and one for low pressure steam.

Modification P00008 Contract N62474-79-C-5382 Page 8 of 10 R&M-9 8. Consideration. Contractor and the Government have determined that over the ------------- remaining term of the Contract the Initial Plant is projected to generate a total output in excess of the output Contractor is required to produce to satisfy its obligation for NAVWPNCEN Power. Use of the geothermal resource for that purpose by the Contractor is authorized by this Modification P00008. In consideration for such use of the resource as well as the other changes contained in this Modification P00008, the Contractor hereby obligates itself and promises to pay the Government the sum of $25,000,000 on or before 31 December 2009. That payment shall be secured by funds placed monthly by Contractor in escrow beginning two months after commercial operations for the Initial Plant have commenced at a rate sufficient to total (assuming interest at a rate of 10% per annum, adjusted annually according to experience) no less than $25,000,000 on 31 December, 2009. A default pursuant to this Section IV.C.8 shall not affect the right of the Financing Parties to Quiet Enjoyment." [5] A new Section IV.D. is added to the Contract to read in full as follows: "D. Provisions Governing Service from Subsequent Plants/Projects. ------------------------------------------------------------- Contractor will become obligated to provide electric service beyond the requirements of NAVWPNCEN Power when the contract negotiations for a subsequent geothermal plant are completed. Contractor is in Phases A or B with respect to all contract work except the work relating to the Initial Plant which is in Phase C. Pursuant to the terms of the Contract, the Contractor agrees to submit to Government by 28 February 1986, the cost and price data to begin the negotiations with the Government. Such negotiations shall address the price and other terms and conditions necessary and appropriate to provide Contractor a basis to seek financing for the design, construction and operation of two additional geothermal energy turbine plants with characteristics similar to those described in Section IV.D.6 hereof. Upon receipt of such data, Government agrees to proceed in good faith with the intent to commence, carry won and complete the said negotiations with Contractor as soon as practicable." [6] A new Section IV.E is added to the Contract to read in full as follows: "E. Precedence of this Modification P00008. Notwithstanding anything --------------------------------------- in the Contract, or appendices or exhibits thereto, the provisions of this Modification P00008 shall take precedence over all other typewritten portions of the Contract and/or its appendices, General Provisions, and other writings." Modification P00008 Contract N62474-79-C-5382 Page 9 of 10 R&M-10 [7] Section VI.J. of the Contract is amended to read as follows: "J. Schedule. The schedule for completion of work to be performed with -------- respect to each geothermal power plant under this Contract is set forth in the appropriate portion of Section IV.C or IV.D hereof. Each such schedule is intended to specify maximum periods of time for the key elements of work unless unforeseen delays (including and not limited to regulatory agency approvals) are encountered which cannot be overcome by the parties exercising due diligence. Each such schedule represents the maximum times the Navy considers appropriate, but the Navy is desirous of completing each phase in the least time possible." [8] Section VI.N of the contract is modified to include an additional interconnection point by adding the following after the word "Meridian" on line 3 of pg 25 Contract Modification P00004: "or SCE Inyokern substation SE Corner Section 20, Township 26 South, Range 39 East Mount Diablo Base Line and Meridian." [9] The first full paragraph on page E-4 of Appendix E to the Contract is deleted and a new paragraph is added to read in full as follows: "The designated delivery point at NAVWPNCEN China Lake is that point at which electrical service is delivered to NAVWPNCEN Under the Utility Service Contract No. N62474-70-C-1201/1054 (the 'SCE/NAVWPNCEN Contract') by and between Government and Southern California Edison company ('SCE'). Government and Contractor agree the additional designated delivery points described in paragraph B of this Appendix E for NAVWPNCEN (to wit: Harvey Field, I.D. No. 2 and Laurel Mountain, I.D. No. 99) are not included in the service provided under the SCE/NAVWPNCEN Contract and are not a service to be provided by Contractor." [10] The effective date of this modification P00008 is 13 Feb 86 . ------------ Modification P00008 Contract N62474-79-C-5382 Page 10 of 10 R&M-11 AMENDMENT OF SOLICITATION/MODIFICATION OF CONTRACTPage 1 of 2 Pages 1.

DATE SIGNED 17 AUG 1987 --------------- R&M-1 N62474-79-C-5382 Modification P00011 Page 2 of 6 This modification P00011 refers to Contract N62474-79-C-5382 of December 6, 1979, as modified from time to time (the "Contract"). Unless modified in subsequent paragraphs of this modification P00011, all terms and conditions of this Contract remain the same. The Contract is hereby modified as follows: [1] The first paragraph of Section II. is changed to read as follows: II. CONSTRAINTS ----------- It shall be the responsibility of the Contractor to conform to and abide by all legally applicable statutes; ordinances; rules and regulations and all permit, approval, and easement requirements relating to the development of the geothermal resource at the Coso KGRA area, access to and from the general sites, and construction on and use of property under the control of NAVWPNCEN China Lake. In addition to the laws and regulations identified in Environmental Protection Plan, Section V, and the terms of this contract, the Contractor is referred to Naval Weapons Center Instructions (see Appendix "G"); the Geothermal Resources Operational Orders as published by the Geological Survey; the Geothermal Steam Act; the Geothermal Energy Research, Development and Demonstration Act; the Federal Land Planning and Management Act; the Defense Withdrawal Act of 1958 (P.L. 85-337); Title 30, the Code of Federal Regulations; and the Occupational Safety and Health Act, or any successor statutes thereto, all as from time to time amended. Unless specifically advised by the Contracting Officer to the contrary, the Contractor shall meet the legally applicable requirements of all State and Local Laws and Regulations. This list is not all inclusive and it is the sole responsibility of the Contractor to acquaint itself with all legally applicable Federal, State and local laws, regulations, and other legal constraints or requirements. Because of the nature of the NAVWPNCEN mission, the Government has placed certain constraints on geothermal operations within the boundaries of NAVWPNCEN. These constraints ensure the safe and economical development of and production of the geothermal resources within the NAVWPNCEN boundary and ensure that any exploration, development, or production does not conflict with the mission of NAVWPNCEN. All on-site and other inspection performed by the Government will be at Government's cost. R&M-2 N62474-79-C-5382 Modification P00011 Page 3 of 6 [2] Section I.C. is amended to read in full as follows: C. Term. ---- This contract shall continue in effect for a period of thirty years from the date of award. The Government has a unilateral right to extend the term of this Contract for an additional ten (10) year term by the giving of written notice to the Contractor not less than 180 days in advance of the contract completion date. If the Government shall exercise this option, the extended contract shall not be considered to include this option provision. The Contractor understands that the Government requires Congressional approval to exercise any option for the extension of the term of this Contract pursuant to this clause. If the Government shall exercise this option, the Government's compensation from the Units shall be as follows: (a) such compensation from Unit I-1 shall remain as provided under IV.C hereof; and (b) Government's share of all PURPA revenues for the option period from Unit I-2 and/or Unit I-3 shall be twenty-two (22) percent. [3] Section III.D.1. is amended to read in full as follows: D. Incremental Development of Geothermal Power Generation ------------------------------------------------------ 1. At such time as the existence of a commercial geothermal resource has been established by the Contractor, the Contractor shall proceed to design and install power generation plant(s) of sufficient capacity to produce and deliver the proposed capacity adequate to provide electrical service to at least NAVWPNCEN China Lake, but not in excess of the generating capacity for which the parties have agreed to hereunder. [4] A new Section III.E. is added to the contract to read in full as follows: E. Expansion Beyond NAVWPNCEN -------------------------- The Government and the Contractor have determined that the entitlement provided to the Government with respect to NAVWPNCEN pursuant to Section IV.C.1 of the contract is not appropriate as Government entitlement with respect to expansion beyond the generating capacity of Unit I-1. A different method for determination of such entitlement has accordingly been negotiated and agreed to by the parties and the provisions controlling said expansion and Government's entitlement shall supersede the provisions of paragraphs A, B, C and D of Section III of the contract. [5] Section IV.C.2.(b) is amended to change "Unit 1" to read "Unit I-1". R&M-3 N62474-79-C-5382 Modification P00011 Page 4 of 6 [6] Section IV. Paragraph D. is amended to read in full as follows: D. Provisions Governing Electric Generating Capacity Beyond NAVWPNCEN To --------------------------------------------------------------------- and Including 75 MW of Service ------------------------------ In General, the Government and the Contractor have mutually agreed to increase the amount of power than can be developed from the Government's geothermal resource at NAVWPNCEN beyond the requirement of NAVWPNCEN as provided under Section IV.C hereof to 75 MW of nameplate rating. It is acknowledged that the nameplate rating of the geothermal plants installed by the Contractor may differ as much as 25% plus or minus from the generating capacity of said geothermal plants. In order to arrange for equity and debt financing and assistance for the field and development to 75 MW of generating capacity the Government and Contractor will cooperate as follows: 1. Contractor will assign to one or more legal entities (partnerships, corporations or proprietorships) involving other parties certain rights which Contractor has been granted under the Contract. All such assignments require Government's consent and such consent will not be unreasonably withheld. If consent is given by Government, no additional consideration is required. The Government will not consent to assignments that contain legal constraints on Government or are contrary to prior assignment. Such assignments, lacking Government consent, shall not be effective. 2. The right of reassignment is extended to Contractor's assignees and their assignments, provided that all such reassignments require the Government's consent in order to be effective. If consent is given by the Government, no additional consideration is required. 3. Definitions ----------- Unless the context otherwise clearly requires, each of the following terms, when used in this contract or in any appendix or attachment thereto with initial capitals, will have the meaning set forth for such term below: (a) "Unit" means a specific turbine-generator set and its associated facilities, exclusive of all geothermal resources and wells, designated by a number. For example, the facility for NAVWPNCEN is referred to as Unit I-1 in Section IV.C.2(b) hereof. As of the execution date of this contract modification P00011, Contractor contemplates increasing the generating facilities located at the developable lands in two increments. Each increment is expected to consist of a Unit with a nameplate rating of 25 MW and will be located at or adjoining the site of the Initial Plant (Unit I-1). These two increments are hereby designated Unit I-2 and Unit I-3, respectively. R&M-4 N62474-79-C-5382 Modification P00011 Page 5 of 6 (b) "Unit Owner" means the joint venture, corporation or other business combination identified as the owner of a Unit in an assignment of rights by Contractor under this contract. (c) "Unit Financing Party" means the firm or firms identified as such with respect to a Unit in an assignment of right by Contractor under this contract. (d) "Unit Resource" means the geothermal resources and wells associated with a specific Unit. (e) "Unit Project" means all elements of permitting, licensing, designing, constructing, erecting, financing, owning, operating, leasing, and manufacturing a specific Unit and/or (where specifically indicated) Unit Resource and receiving, utilizing and disbursing the revenues generated thereby. (f) "PURPA Revenues" means any and all sums of money payable to Contractor or its assigns under the provisions of its PURPA Contract with Southern California Edison Company as capacity payments, energy payments and bonus capacity payments. (g) "SCE" means the Southern California Edison Company, as defined in the PURPA Contracts. (h) "On Line" means the first date a Unit is deemed by the parties to have commenced commercial operation under the contract for such Unit. 4. Pricing Mechanism ----------------- (a) Unit I-2 and Unit I-3. The Contractor or its assigns shall pay the Government a share of all gross PURPA revenues earned by the Contractor or its assigns from Southern California Edison pursuant to the PURPA Contract for electricity generated from Unit I-2 and Unit I-3. The Government share of gross PURPA revenue shall be as follows: First three years after first such Unit goes On Line 4 percent Next seven years 10 percent Next five years 15 percent Remaining years until contract completion 20 percent (b) The payments due to the Government hereunder shall begin for each Unit separately with the date upon which that Unit first goes On Line and said payments shall continue until the completion date of this Contract with respect to each such Unit, including all extensions hereof. R&M-5 N62474-79-C-5382 Modification P00011 Page 6 of 6 (c) The SCE payments for Units I-2 and I-3 are governed by the Southern California Edison PURPA Contract for initial Turbine and therefore as a condition to implementing the provisions of Section IV.D.3 hereof, the Government and the Contractor do hereby agree to negotiate in good faith to establish appropriate allocation provisions affecting the relative rights of Government, Contractor, and the Owners and Financing Parties of the Initial Plant in said SCE PURPA Contract and payments thereunder. (d) Inasmuch as the construction of all the additional Units is subject to many uncertainties, if these unknown factors affect the expected development plan the parties agree to accommodate those changes by providing for alternate equivalent arrangements. [7] Add a new Section IV.F. to read as follows: F. Provisions Governing Service from Subsequent Projects. ----------------------------------------------------- The Contractor will become obligated to provide electric service beyond the requirements provided for in Section IV.D. of the contract when contract negotiations for a contemplated additional geothermal plant are completed. Such negotiations shall address terms and conditions necessary and appropriate to provide the Contractor a basis to seek financing for the design, construction and operation of such additional plant. The Government agrees to proceed in good faith with the intent to commence, carry on and complete said negotiations in a timely manner. [8] Section VI.J. is amended to add the following: Unit I-2 and Unit I-3 shall be complete and shall be on-line on or before June 3, 1989.

The Contractor understands that the Government requires Congressional approval to exercise any option for the extension of the term of this Contract pursuant to this clause. If the Government shall exercise this option, the Government's compensation from the Units shall be as follows: (a) such compensation from Unit I-1 shall remain as provided under IV.C hereof; (b) the Government's share of all gross PURPA revenues for the option period from Unit I-2 and/or Unit I-3 shall be twenty-two (22) percent; and (c) the Government's share of all gross PURPA revenues for the option period from either or any of Unit II-1, Unit II-2, and Unit II-3 shall be twenty-two (22) percent. [2] Section IV. Paragraph D. is amended to read in full as follows: D. Provisions Governing electric Generating Capacity Beyond NAVWPNCEN To --------------------------------------------------------------------- and Including 160 MW of Service ------------------------------- In General, the Government and the Contractor have mutually agreed to increase the amount of power than can be developed from the Government's geothermal resource at NAVWPNCEN beyond the requirement of NAVWPNCEN as provided under Section IV.C hereof to 160 MW of nominal nameplate rating. It is acknowledged that the nominal nameplate rating of the geothermal plants installed by the Contractor may differ as much as 25% plus or minus from the generating capacity of said geothermal plants. In order to arrange for equity and debt financing and assistance for the field and development to 160 MW of generating capacity the Government and Contractor will cooperate as follows: 1. Contractor will assign to one or more legal entities (partnerships, corporations or proprietorships) involving other parties certain rights which Contractor has been granted under the Contract. All such assignments require Government's consent and such consent will not be unreasonably withheld. If consent is given by Government, no additional consideration is required. The Government will not consent to assignments that contain legal constraints on Government or are contrary to prior assignment. Such assignments, lacking Government consent, shall not be effective. R&M-2 N62474-79-C-5382 Modification P00012 Page 3 of 5 2. The right of reassignment is extended to Contractor's assignees and their assignments, provided that all such reassignments require the Government's consent in order to be effective. If consent is given by the Government, no additional consideration is required. 3. Definitions ----------- Unless the context otherwise clearly requires, each of the following terms, when used in this contract or in any appendix or attachments thereto with initial capitals, will have the meaning set forth for such term below: (a) "Unit" means a specific turbine-generator set and its associated facilities, exclusive of all geothermal resources and wells, designated by a number. For example, the facility for NAVWPNCEN is referred to as Unit I- 1 in Section IV.C.2(b) hereof. As of the execution date of this contract modification P00012, Contractor contemplates increasing the generating facilities located at the developable lands in five increments. Each increment is expected to consist of a Unit with a nominal nameplate rating of 25 MW. Two such increments are contemplated to be located at or adjoining the site of the Initial Plant (Unit I-1). These two increments are hereby designated Unit I-2 and Unit I-3, respectively. Three additional increments are also contemplated to be added to the developable lands at a single site expected to be located within the five square mile are described in Appendix A at page A-4 hereof. These three increments are hereby designated Unit II-1, Unit II-2, and Unit II-3 respectively. Not withstanding the above, the parties understand and agree that the contemplated number of units may be increased or decreased to accommodate development requirements and in such event this agreement will be administratively amended to reflect such a change. (b) "Unit Owner" means the joint venture, corporation or other business combination identified as the owner of a Unit in an assignment of rights by Contractor under this contract. (c) "Unit Financing Party" means the firm or firms identified as such with respect to a Unit in an assignment of right by Contractor under this contract. (d) "Unit Resource" means the geothermal resources and wells associated with a specific Unit. (e) "Unit Project" means all elements of permitting, licensing, designing, constructing, erecting, financing, owning, operating, leasing, and manufacturing a specific Unit and/or (where specifically indicated) Unit Resource and receiving, utilizing and disbursing the revenues generated thereby. (f) "PURPA Revenues" means any and all sums of money payable to Contractor or its assigns under the provisions of its PURPA Contract with Southern California Edison Company as capacity payments, energy payments and bonus capacity payments. R&M-3 N62474-79-C-5382 Modification P00012 Page 4 of 5 (g) "SCE" means the Southern California Edison Company, as defined in the PURPA Contracts. (h) "On Line" means the first date a Unit is deemed by the parties to have commenced commercial operation under the construction contract for such Unit. 4. Pricing Mechanism ----------------- (a) Unit I-2 and Unit I-3. The Contractor or its assigns shall pay the Government a share of all gross PURPA revenues earned by the Contractor or its assigns from Southern California Edison pursuant to the PURPA Contract for electricity generated from Unit I-2 and Unit I-3. The Government share of gross PURPA revenue shall be as follows: First three years after first such Unit goes On Line 4 percent Next five years 10 percent Next five years 18 percent Remaining years until contract completion 20 percent (b) Unit II-1, Unit II-2 and Unit II-3. The Contractor or its assigns shall pay the Government a share of all gross PURPA revenues earned by the Contractor or its assigns from Southern California Edison pursuant to the PURPA Contract for electricity generated from Unit II-1, Unit II-2 and Unit II-3. The Government share of gross PURPA revenue shall be as follows: First five years after first such Unit goes On Line 4 percent Next five years 10 percent Next five years 18 percent Remaining years until contract completion 20 percent (c) The payments due to the Government hereunder shall begin for each Unit separately with the date upon which that Unit first goes On Line and said payments shall continue until the completion date of this Contract with respect to each such Unit, including all extensions hereof. (d) The SCE payments for Units I-2 and I-3 are governed by the Southern California Edison PURPA Contract for the initial Turbine and therefore as a condition to implementing the provisions of Section IV.D. hereof, the Government and the Contractor do hereby agree to negotiate in good faith to establish appropriate allocation provisions affecting the relative rights of Government, Contractor, and the Owners and Financing Parties of the Initial Plant in said SCE PURPA Contract and payments thereunder. Allocation provisions shall be based on metered output of each of units I- 1, I-2, and I-3. R&M-4 N62474-79-C-5382 Modification P00012 Page 5 of 5 (e) Inasmuch as the construction of all the additional Units is subject to many uncertainties, if these unknown factors affect the expected development plan the parties agree to accommodate those changes by providing for alternate equivalent arrangements. [3] Section VI.J. is amended to add the following: Unit II-1, Unit II-2 and Unit II-3 shall be complete and shall be on-line on or before January 31, 1990. [4] Section VIII.2.(c) is amended to read in full as follows: (c) Ceiling amount for Units I-1, I-2, and I-3: So long as the parties have agreed on a delivered price and a delivery schedule for the Contractor to provide electric power service only to NAVWPNCEN, the Governments's liability to the Contractor pursuant to this clause shall not exceed $67,500,000. This ceiling amount is derived by multiplying 25 megawatts by $2,700,00 per megawatt. When and as the parties agree on a delivered price and a delivery schedule for the Contractor to provide electric power service to designated delivery points in addition to NAVWPNCEN, the foregoing $67,500,000 ceiling shall be increased by an amount equal to the average peak load (expressed in megawatts) of these additional designated delivery points during the prior twelve months multiplied by $2,500,000 per megawatt until the average peak load of the designated delivery points for which the parties have agreed on a delivered price and a delivery schedule (including NAVWPNCEN) totals 50 megawatts. Thereafter, until the average peak load of the designated delivery points for which the parties have agreed on a delivered price and a delivery schedule (including NAVWPNCEN) totals 75 megawatts, the multiplier shall be $1,400,000 per megawatt. Thus, at the time that the parties agree on a delivered price and a delivery schedule for designated delivery points (including NAVWPNCEN) with an average peak load of 75 megawatts, the ceiling amount shall be $165,000,000. [5] Add a new Section VIII.2.(d) to read in full as follows: (d) Ceiling amount for Units II-1, II-2, and II-3: So long as the parties have agreed on a delivered price and a delivery schedule for the Contractor to provide additional electric power beyond that covered under paragraph VIII.2.(c) above, the ceiling amount shall be derived as follows: for the first additional 25 megawatts of installed nameplate capacity, the amount due to Contractor hereunder shall not exceed $67,500,000. This ceiling amount is derived by multiplying 25 megawatts by $2,700,00 per megawatt. This ceiling amount shall be increased by $2,500,000 per megawatt for each additional megawatt of nameplate capacity between 25 megawatts and 50 megawatts and shall be increased by $2,300,000 per megawatt for each additional megawatt of nameplate capacity between 50 megawatts and 75 megawatts. Thus at the time the total additional nameplate capacity for Units II-1, II-2, and II-3 totals 75 megawatts, the ceiling amount under this Section VIII.2.(d) shall be $187,500,000.

Consideration. ------------- a. Contractor and the Government have determined that over the remaining term of the Contract the initial plant is projected to generate a total output in excess of the output Contractor is required to produce to satisfy its obligation for Naval Air Weapons Station, China Lake power. Use of the geothermal resource for production of such excess output is authorized by this Modification P00008. b. In consideration for such use of the resource as well as the other changes contained in this Modification P00008, the Contractor hereby obligates itself and promises to pay the Government the sum of $25,000,000 on or before 31 December 2009. That payment shall be secured by funds placed monthly by Contractor in escrow beginning two months after commercial operations of the Initial Plant have commenced. However, existence of the escrow does not relieve Contractor of the obligation to ensure that the Government receives a total of $25,000,000 as previously stated. c. The escrow shall be established with an institution insured by the Federal Deposit Insurance Corporation. Terms and conditions of the escrow agreement shall be subject to approval by the Government and shall be substantially the same as those in the attached draft agreement, Exhibit "A"; permitted investments for the escrow fund shall be only those listed in the attached Exhibit "A". The escrow agreement shall require the escrow agent to periodically provide the Government with statement showing escrow account activity and balance. Government shall have the right to audit the escrow account from time to time. d. Contractor shall deposit in escrow each month an amount of not less than $50,000. Without approval in advance by the Government, Contractor shall neither make withdrawals from, nor encumber, the escrow fund. f. A default pursuant to this Section IV.C.8 shall not affect the right of the Financing Parties to quiet enjoyment. R&M-2 AMENDMENT OF SOLICITATION/MODIFICATION OF CONTRACT Page 1 of 2 Pages 1.

DATE SIGNED 4 OCT 94 ------------ R&M-1 ATTACHED TO AND MADE A PART OF CONTRACT MODIFICATION N62474-79-C-5382-P00029 The Navy herein consents to the exchange and transfer of steam between the Navy I and Navy II facilities located at Coso subject to the following conditions: 1. Transfers will be of steam for production purposes of generating electric power. Transfers of brine and/or condensate may be either for flashing to power-generating steam, for injection, or for prevention of scale. 2. All transfers shall be strictly monitored by the Navy and California Energy Company, Inc. (CECI) by means of continuous flow gauging and recording of flow through the gauge(s). Such gauging shall be by means of mutually-agreed upon devices which shall be calibrated and certified prior to installation and operation. Each gauge shall be re-calibrated at least once a year by using a mutually-agreed-upon technique. The Navy may require that this re-calibration be performed by an independent third-party, to be approved by the Navy. 3. Gauging points for particular pipeline(s) to be used for steam, brine, and/or condensate transfer between Navy I and Navy II producing areas shall be agreed upon by the Navy and CECI in advance of installation and operation of such pipeline(s). Flow at the gauging points shall be recorded daily in units of pounds of mass and shall be reported to the Navy on a weekly basis as part of routine reporting of geothermal fluid production and electric power generation. 4. The Navy shall be compensated according to the formulas found in the Exchange Agreement dated January 11, 1994, Exhibit "A", which was signed by the partners in the Navy I and Navy II development projects. The partners may amend these formulas from time to time, with the Navy's consent. 5. In the event it is determined that the transfer of steam, brine, and/or condensate between facilities is materially detrimental* to the Navy, the Navy reserves the right to suspend, terminate, or withdraw its consent to the transfers at any time, notwithstanding any provision in the Exchange Agreement or in this modification to the contrary. CECI shall hold the Navy harmless from any and all related monetary damages resulting from such suspension, termination, or withdrawal and agrees to indemnify the Navy against all claims of itself, its partners, and any other parties in this regard. 6. Such suspension, termination, or withdrawal shall be effective no later than 15 days after delivery to CECI of written notice to cease such exchanges. The navy may, in its discretion, cancel its notice of suspension, termination, or withdrawal prior to the notice taking effect. R&M-2 ATTACHED TO AND MADE A PART OF CONTRACT MODIFICATION N62474-79-C-5382-P00029 7. Reservoir model simulations shall be run at least every six months, or more frequently, as needed, using up-to-date production and monitoring information. The results of such simulations shall be conveyed to the Geothermal Program Office immediately upon completion. *NOTE: For the purposes of this modification, materially detrimental is defined as: Any reservoir-related change in the overall production enthalpy or steam rate within the Navy I and Navy II areas which is beyond one standard deviation from CECI's simulation-based forecast of such values, using the most recent of these forecasts prior to the observed change. The simulation-based forecast shall be updated every six months, or more frequently, as needed. The standard deviation is calculated on the differences between monthly measurements and history- matched values in the simulator for the period from the start of production to the time of the forecast. The size of these historical differences is a statistical measure of the quality of the simulation; and the accuracy of the forecast based on the simulation is not expected to be any better than the accuracy of the history-match. Observed changes in enthalpy or steam rate may occur in a period of time as short as one month, or they may be more protracted (such as over a six-month period). Changes of this nature can be construed as materially detrimental to the Navy to the extent that they would impact the Navy's ability to realize its long-term goals for the geothermal resource at Coso.

DATE SIGNED 19 Dec 94 ------------- R&M-1 ATTACHED TO AND MADE A PART OF CONTRACT MODIFICATION N62474-79-C-5382-P00030 PAGE 2 OF 4 The Navy herein consents to the exchange and transfer of steam between the Navy and Bureau of Land Management (BLM) facilities located at Coso subject to the following conditions: 1. Transfers will be of steam for the purpose of generating electric power. Transfers of brine and/or condensate will be for injection or prevention of scale. 2. All transfers shall be strictly monitored by the Navy and California Energy Company, Inc. (CECI) by means of continuous flow gauging and recording of flow through the gauge(s). Such gauging shall be by means of mutually-agreed- upon devices which shall be calibrated and certified prior to installation and operation. Each gauge shall be re-calibrated at least once a year by using a mutually-agreed-upon technique. The Navy may require that this re-calibration be performed by an independent third-party, to be approved by the Navy. 3. Gauging points for particular pipeline(s) to be used for steam, brine, and/or condensate transfer between Navy contract lands and BLM lease lands shall be agreed upon by the Navy, BLM, and CECI in advance of installation and operation of such pipeline(s). Flow at the gauging points shall be recorded daily in units of pounds of mass and shall be reported to the Navy on a weekly basis as part of routine reporting of geothermal fluid production and electric power generation. 4. The Navy shall be compensated on the basis of Equivalent Megawatt-Hours (MWh) for steam transferred to BLM power plants. Determination of the MWh shall be made by first calculating the Thermal Capacity (in BTU/1b-m) of steam transferred using a formula that is mutually-agreed upon by the Navy, BLM and CECI. Using this formula, the total Thermal Value (in BTU) of the steam that is transferred shall be determined by multiplying the Thermal Capacity by the total mass that passes by the gauge. Determination of the Thermal Capacity of the steam shall take into account the temperature, pressure, and amount of non- condensible gas that the steam contains. This value shall be updated as necessary to ensure accurate determination of Thermal Value, Thermal Value shall be converted into MWh and shall be the basis for calculating revenue due to the Navy. The MWh shall be based on the average efficiency of the Navy turbines in converting steam to electricity. 5. Revenues due the Navy for steam transferred by CECI from the Navy contract lands to power plants on BLM lands shall be calculated by multiplying the MWh times the prevailing energy price ($/MWh) for the originating project. Prevailing energy price for a given monthly billing period is defined as an amount equal to the Total Current Energy Payment divided by the net MWh as shown on the Southern California Edison Company - Statement of Energy Purchased. This value shall then be multiplied by the average of the prevailing revenue share rates for Navy I and Navy II to determine the amount due the Navy. R&M-2 ATTACHED TO AND MADE A PART OF CONTRACT MODIFICATION N62474-79-C-5382-P00030 PAGE 3 OF 4 In the event steam transferred from Navy to BLM during the given month results in CECI's BLM power plants receiving capacity payments, the Navy shall be compensated on a pro rata basis for steam contributed toward earning those capacity payments. Such capacity payments shall include "capacity", "bonus capacity", and "as available capacity payments". The extent of the Navy contribution, if any, toward reaching capacity payment thresholds shall be based on the amount of MWh produced with Navy steam. The Navy-produced portion of those payments will then be subject to revenue sharing based on the average of the prevailing revenue share rates for Navy I and Navy II. 6. The Navy shall also be compensated for steam transferred from BLM lease lands to Navy Power plants in the same manner as above with the following exception: The Navy revenue share rate for MWh transferred from the BLM lease lands to power plants on Navy contract lands shall be the difference between: a. the average of the prevailing royalty rates for Navy I and Navy II; and b. the actual percentage of the gross value of the transferred MWh, paid to the Minerals Management Service (MMS) based on the netback calculation at the BLM project. CECI will document this actual percentage by submitting to the Navy, each month, a copy of the Southern California Edison Company "Statement of Energy Purchased" and a copy of the "Report of Sales and Royalty Remittance" (MMS-2014) for the BLM project. 7. Revenues due the Navy from the transfer of steam shall be calculated and paid on a monthly basis along with the revenue from sale of electricity at Navy I and Navy II. They shall, however, be separately listed from the Navy electricity sales revenue amounts. 8. In the event it is determined that the transfer or exchange of steam between facilities is materially detrimental* to the Navy, the Navy reserves the right to suspend, terminate, or withdraw its consent to such transfers at any time notwithstanding any provision in other contract modifications or in this modification to the contrary. CECI shall hold the Navy harmless from any and all related monetary damages resulting from such suspension, termination, or withdrawal and agrees to indemnify the Navy against all claims of itself, its partners, and any other parties in this regard. 9. Such suspension, termination, or withdrawal shall be effective no later than 15 days after delivery to the CECI of written notice to cease such exchanges. The Navy may, in its discretion, cancel its notice of suspension, termination, or withdrawal prior to the notice taking effect. 10. Reservoir model simulations shall be run at least every six (6) months, or more frequently, as needed, using up to date production and monitoring information. The results of such simulations shall be conveyed to the Geothermal Program Office immediately upon completion. R&M-3 ATTACHED TO AND MADE A PART OF CONTRACT MODIFICATION N62474-79-C-5382-P00030 PAGE 4 OF 4 *NOTE: For the purposes of this modification, materially detrimental is defined as: Any reservoir-related change in the overall production enthalpy or steam rate within the Navy I and Navy II, or BLM producing areas which is beyond one standard deviation from CECI's simulation-based forecast of such values, using the most recent of these forecasts prior to the observed change. The simulation-based forecast shall be updated every six months, or more frequently, as needed. The standard deviation is calculated on the differences between monthly measurements and history-matched values in the simulator for the period from the start of production to the time of the forecast. The size of these historical differences is a statistical measure of the quality of the simulation, and the accuracy of the forecast based on the stimulation is not expected to be any better than the accuracy of the history-match. Observed changes in enthalpy or steam rate may occur in a period of time as short as one month, or they may be more protracted (such as over a six-month period). Changes of this nature can be construed as materially detrimental to the Navy or BLM to the extent that they would impact the either the Navy's or BLM's ability to realize its long-term goals for the geothermal resource at Coso.
