                                  LEASE TERMS

Sec. 1.  Rentals -- Rentals shall be paid to proper office of lessor in advance
of each lease year until there is production in commercial quantities from the
leased lands.  Annual rental rates per acre or fraction thereof are:  $1 for
noncompetitive leases and $2 for competitive leases.
  If this lease or a portion thereof is committed to an approved cooperative or
unit plan which includes a well capable of producing leased resources, and the
plan contains a provision for allocation of production, royalties shall be paid
on the production allocated to this lease.  However, annual rentals shall
continue to be due for those lands not within a participating area.
  Failure to pay annual rental, if due, on or before the anniversary date of
this lease (or next official working day if office is closed) shall
automatically terminate this lease by operation of law.  Rentals may be
suspended by the Secretary upon a sufficient showing by lessor.

Sec. 2.  Royalties -- Royalties shall be paid to proper office of lessor.
Royalties shall be computed in accordance with regulations and orders.  Royalty
rates on production are: 10 percent for steam, heat, or energy; 5 percent for
byproducts; and 5 percent for demineralized water.
  Lessor reserves the right to establish reasonable minimum values on production
after giving lessee notice and an opportunity to be heard.  Royalties shall be
due and payable on the last day of the month following the month in which
production occurred.
  Minimum royalty shall be due for any lease year beginning on or after the
commencement of production in commercial quantities in which royalty payments
aggregate less than $2 per acre.  Lessor shall pay such difference at the end of
lease year. This minimum royalty may be waived, suspended, or reduced, and the
above royalty rates may be reduced for all or portions of this lease if the
Secretary determines that such action is necessary to encourage the greatest
ultimate recovery of the leased resources, or is otherwise justified.

Sec. 3.  Bonds -- Lessee shall file and maintain any bond required under
regulations.

Sec. 4.  Diligence, rate of development, unitization, and drainage -- Lessee
shall perform diligent exploration as required by regulations and shall prevent
unnecessary damage to, loss of, or waste of leased resources.  Lessor reserves
right to specify rates of development and production in the public interest and
to require lessee to subscribe to a cooperative or unit plan, within 30 days of
notice, if deemed necessary for proper development and operation of the area,
field, or pool embracing these leased lands.  Lessee shall drill and produce
wells necessary to protect leased lands from drainage or pay compensatory
royalty for drainage in amount determined by lessor.

Sec. 5.  Documents, evidence, and inspection -- Lessee shall file with proper
office of lessor, not later than (30) days, after effective date thereof, any
contract or evidence of other arrangement for the sale or disposal of
production.  At such times and in such form as lessor may prescribe, lessee
shall furnish detailed statements showing amounts and quality of all products
removed and sold, proceeds therefrom, and amount used for production purposes or
unavoidably lost.  Lessee shall be required to provide

                                     R&M-3


plots and schematic diagrams showing development work and improvements, and
reports with respect to parties in interest, expenditures, and depreciation
costs.
  In the form prescribed by lessor, lessee shall keep a daily drilling record, a
log, and complete information on well surveys and tests and keep a record of
subsurface investigations and furnish copies to lessor when required.  Lessee
shall keep open at all reasonable times for inspection by any authorized officer
or lessor, the leased premises and all wells, improvements, machinery, and
fixtures thereon, and all books, accounts, maps, and records relative to
operations, surveys, or investigations on or in the leased lands.  Lessee shall
maintain copies of all contracts, sales agreements, accounting records, and
documentation such as billings, invoices, or similar documentation that support
costs claimed as manufacturing, preparation, and/or transportation costs.  All
such records shall be maintained in lessee's accounting offices for future audit
by lessor.  Lessee shall maintain required records for 6 years after they are
generated or, if an audit or investigation is underway, until released of the
obligation to maintain such records by lessor.
  Notwithstanding existence of this lease, information obtained under this
section shall be closed to inspection by the public in accordance with the
Freedom of Information Act (5 U.S.C. 552).

Sec. 6.  Conduct of operations -- Lessee shall conduct operations in a manner
that minimizes adverse impacts to the land, air, and water, to cultural,
biological, visual, and other resources, and to other land uses or users.
Lessee shall take reasonable measures deemed necessary by lessor to accomplish
the intent of this section.  To the extent consistent with leased rights
granted, such measures may include, but are not limited to, modification to
siting or design of facilities, timing of operations, and specification of
interim and final reclamation measures.  Lessor reserves the right to continue
existing uses and to authorize future uses upon or in the leased lands,
including the approval of easements or rights-of-ways.  Such uses shall be
conditioned so as to prevent unnecessary or unreasonable interference with
rights of lessees.
  Prior to disturbing the surface of the leased lands, lessee shall contact
lessor to be appraised of procedures to be followed and modification or
reclamation measures that may be necessary.  Areas to be disturbed may require
inventories or special studies to determine the extent of impacts to other
resources.  Lessee may be required to complete minor inventories or short term
special studies under guidelines provided by lessor.  If in the conduct of
operations, threatened or endangered species, objects of historic or scientific
interest, or substantial unanticipated environmental effects are observed,
lessee shall immediately contact lessor.  Lessee shall cease any operations that
would result in the destruction of such species or objects.

Sec. 7.  Production of byproducts -- If the production, use, or conversion of
geothermal resources from these leased lands is susceptible of producing a
valuable byproduct or byproducts, including commercially demineralized water for
beneficial uses in accordance with applicable State water laws, lessor may
require substantial beneficial production or use thereof by lessee.

Sec. 8.  Damages to property -- Lessee shall pay lessor for damage to lessor's
improvements, and shall save and hold lessor harmless from all claims for damage
or harm to persons or property as a result of lease operations.

Sec. 9.  Protection of diverse interests and equal opportunity -- Lessee shall
maintain a safe working environment in accordance with standard industry
practices and take measures necessary to protect the health and safety of the
public.  Lessor reserves the right to ensure that production is sold at
reasonable prices and to prevent monopoly.
  Lessee shall comply with Executive Order No. 11246 of September 24, 1965, as
amended, and regulations and relevant orders of the Secretary of Labor issued
pursuant thereto.  Neither lessee nor lessee's subcontractor shall maintain
segregated facilities.

Sec. 10.  Transfer of lease interests and relinquishment of lease -- As required
by regulations, lessee shall file with lessor, any assignment or other transfer
of an interest in this lease.  Lessor may relinquish this lease or any legal
subdivision by filing in the proper office a written relinquishment, which shall
be effective as of the date of filing, subject to the continued obligation of
the lessee and surety to pay all accrued rentals and royalties.

Sec. 11.  Delivery of premises -- At such time as all or portions of this lease
are returned to lessor, lessee shall place all wells in condition for suspension
or abandonment, reclaim the land as specified by lessor, and within a reasonable
period of time, remove equipment and improvements not deemed necessary by lessor
for preservation of producible wells or continued protection of the environment.

Sec. 12.  Proceedings in case of default -- If lessee fails to comply with any
provisions of this lease, and the noncompliance continues for 30 days after
written notice thereof, this lease shall be subject to cancellation in
accordance with the Act.  However, if this lease includes land known to contain
a well capable of production in commercial quantities, it may be cancelled only
by judicial proceedings. This provision shall not be construed to prevent the
exercise by lessor of any other legal and equitable remedy, including waiver of
1986the default. Any such remedy or waiver shall not prevent later cancellation
for the same default recurring at any other time.

                                     R&M-4


  Whenever the lessee fails to comply in a timely manner with any of the
provisions of the Act, this lease, the regulations, or formal orders, and
immediate action is required, the Lessor may enter on the leased lands and take
measures deemed necessary to correct the failure at the expense of the Lessor.

Sec. 13.  Heirs and successors-in-interest -- Each obligation of this lease
shall extend to and be binding upon, and every benefit hereof shall inure to,
the heirs, executors, administrators, successors, or assignees of the respective
parties hereto.

                                     R&M-5


                 Navy Constraints On Naval Weapon Center Lands

In addition to the lease terms and requirements contained in the lease forms,
the lessee shall comply with the following Navy constraints unless they are
jointly modified by the Commander, NWC, and the Authorized Officer, Bureau of
Land Management, with the concurrence of the Deputy Conservation Manager (DCM)
for Geothermal, USGS.

The Commander, NWC, is the responsible agent of the Federal Government for the
utilization of the land surface and airspace of NWC.  As such, the Commander,
NWC, is responsible for the protection of the health and safety of all
personnel, military and civilian, within the confines of NWC, and is responsible
for the continuing preservation of the ability of NWC to perform its mission of
air delivered weapons research, development, test, and evaluation.

1.  Access.

    Access to the NWC is a privilege granted by the Commander, NWC. Exercise of
    this privilege requires adherence to NWC traffic regulations, check-in/
    check-out procedures, radiation control measures, environmental controls,
    area access limitations, and electronic emission controls and such other
    published administrative regulations as appropriate. Access shall be on a
    not-to-interfere basis with NWC test schedules, and shall be limited to that
    specific lease block or area being explored, developed or produced. Access
    schedules shall be established on a weekly basis with NWC. NWC shall provide
    uninterrupted short term access for reasons of geothermal safety or other
    drilling incidents requiring access to a specific site for geothermal
    operations. Experience to date shows that in any given month, scheduled and
    unscheduled daylight downtime will not regularly exceed 10% and nighttime
    downtime will not regularly exceed 2%. Access shall require that for each
    lease holder, one responsible contact point shall at all times know who is
    present on NWC lands, and this contact point shall be reachable at all times
    in event evacuation is ordered.

2.  Security.

    The mission of the NWC is such that visitors cannot be granted access to NWC
    lands without going through NWC security procedures. All non-citizen visits
    must be arranged through NWC with a minimum notice of 96 hours for non-
    communist-bloc visitors. The latter will be considered on a case-by-case
    basis. Accessible areas visitors use will be delineated by NWC.

                                     R&M-6


3.  Environmental.

    NWC retains the right to suspend any operation judged by the Center to
    present an imminent threat to the environment. During all operations, all
    federal, state and local environmental standards shall be rigorously
    observed. No components of the environment shall be unnecessarily disturbed.
    NWC shall have the right to impose those emission standards required to
    protect the Center's mission.

4.  Sites and Routes.

    All vehicular traffic shall be limited to routes approved by NWC. Power
    plant sites, drill pad sites, and pipe line routes will be selected subject
    to NWC approval to ensure that such sites will have a minimum impact on NWC
    range operations. All site plans shall be submitted to NWC for review and
    approval. Routes to and from work areas within lease blocks shall be
    approved by NWC.

5.  Shelters.

    Lease operators shall have the option of either moving employees outside NWC
    boundaries upon request of the designated representatives of the Commander,
    NWC, or retiring to NWC approved personnel shelters provided by the lessee
    during those times when the NWC operations require personnel protection at
    the work site.

6.  Radioactive Sources.

    No radioactive sources shall be brought into NWC until appropriate Navy
    permits have been obtained. These permits will be issued after NWC has
    verified the license of the operator to be valid for the proposed effort and
    has approved written standard procedures for use and for handling lost or
    damaged sources.

7.  Injuries and Accidents.

    All disabling injuries occurring within NWC boundaries will be reported
    within 24 hours to NWC. NWC will have the right to suspend any operation
    judged by NWC to present an imminent danger to any personnel on NWC property
    or to government property.

8.  Electronic Radiation.

    Electronic emissions will not be permitted without prior review and
    authorization by the NWC. Periods of emission will be coordinated with the
    Center and, at times, the Center may require electronic emission silence for
    periods of up to four hours.

                                     R&M-7


9.  Plant Protection.

    All wet-heads shall be revetted to a degree acceptable to NWC; all wells so
    designated by NWC shall be fitted with an approved below ground or revetted
    flow limiter; all pipe lines shall be fitted with automatic flow limiters as
    approved by NWC and all power plants shall be equipped with a hardened
    control room approved for continuous occupancy during NWC tests.

10. Information.

    All information on incidents involving both NWC equipment and/or personnel
    and the geothermal operators will be released to the public jointly by NWC
    and the Department of Interior. Particular attention will be given to
    information concerning incidents that have the potential for high public
    interest. Any serious injury or fatality and any geothermal blowout will be
    reported at once to NWC.

11. Military/Government Property.

    All military and government property found on the land surface or embedded
    in the land shall be left in place. NWC shall be informed of the presence of
    all suspected or potentially hazardous material immediately and NWC
    personnel will inspect and remove such material in a timely manner. In case
    of doubt, NWC is to be called for an inspection.

12. Data Exchange.

    Data on flow, chemistry of fluids and reservoir conditions and structure
    shall be provided to NWC with such data to remain proprietary in accordance
    with current practices and procedures as developed by the Deputy
    Conservation Manager and set forth in 30 CFR 270.

13. Legal Jurisdiction.

    Law enforcement on NWC lands will remain the responsibility of NWC. The use
    of geothermal operator employees in a guard function or the contracting by
    the geothermal operator for security guards on NWC lands will be subject to
    review and approval by NWC.

14. Right of Inspection.

    NWC shall have the right of inspection at all times to ensure and verify
    compliance with these constraints.

15. Minor administrative costs incurred by the Naval Weapons Center, i.e.,
    scheduling to avoid conflict with Weapons Center range use, will be
    chargeable to the leaseholder.  For more information call Dr. Carl Austin,
    (714) 939-3411, extension 228.

   portion of the leased lands creates separate leases. Assignee, upon approval
   of assignment, becomes lessee of the Government as to the assigned interest

               PART B:  CERTIFICATION AND REQUEST FOR APPROVAL

1. The assignor certifies as owner of an interest in the above designated lease
   that he/she hereby assigns to the above assignee(s) the rights specified
   above.

2. Assignee certifies as follow:  (a) Assignee is a citizen of the United
   States; an association of such citizens; a municipality; or a corporation
   organized under the laws of the United States or of any State or territory
   thereof.  For the assignment of NPR-A leases, assignee is a citizen, nation,
   or resident alien of the United States or association of such citizen,
   nationals, resident aliens or private, public or municipal corporations, (b)
   Assignee is not considered a minor under the laws of the State in which the
   lands covered by this assignment are located; (c) Assignee's chargeable
   interests, direct and indirect, in either public domain or acquired lands, do
   not exceed 200,000 acres in oil and gas options or 246,080 in oil and gas
   leases in the same State, or 300,000 acres in leases and 200,000 options in
   each leasing District in Alaska, of this is an oil and gas lease issued in
   accordance with the Mineral Leasing Act of 1920 or 51,200 acres in any one
   State if this is a geothermal lease; and (d) All parties holding an interest
   in the assignment are otherwise in compliance with the regulations (43 CFR
   Group 3100 or 3200) and the authorizing Acts.

3. Assignee's signature to this assignment constitutes acceptance of all
   applicable terms, conditions, stipulations and restrictions pertaining to the
   lease described herein.

For oil and gas assignments, the obligation to pay overriding royalties, payment
out of production, carried interests, net profit interests, or such similar
payments or interests increased herein, which, when added to overriding
royalties or payments out of production or other similar interests or payments
previously created, may be suspended by the Secretary at any time upon a
determination that the excess constitutes a burden on lease operations in
accordance with 43 CFR 3103.

For geothermal assignments, an overriding royalty may not be less than one-
fourth (1/4) of one percent of the value of output, nor greater than 50 percent
of the rate of royalty due to the United States when this assignment is added to
all previously created overriding royalties (43 CFR 3241).

I certify that the statements made herein by me are true, complete, and correct
to the best of my knowledge and belief and are made in good faith.

1. The assignor certifies as owner of an interest in the above designated lease
   that he/she hereby assigns to the above assignee(s) the rights specified
   above.

2. Assignee certifies as follows:  (a) Assignee is a citizen of the United
   States:  an association of such citizens; a municipality; or a corporation
   organized under the laws of the United States or of any State or territory
   thereof.  For the assignment of NPR-A leases, assignee is a citizen, nation,
   or resident alien of the United States or association of such citizen,
   nationals, resident aliens or private, public or municipal corporations, (b)
   Assignee is not considered a minor under the laws of the State in which the
   lands covered by this assignment are located; (c) Assignee's chargeable
   interests, direct and indirect, in either public domain or acquired lands, do
   not exceed 200,000 acres in oil and gas options or 246,080 in oil and gas
   leases in the same State, or 300,000 acres in leases and 200,000 acres in
   options in each leasing District in Alaska, if this is an oil and gas lease
   issued in accordance with the Mineral Leasing Act of 1920 or $1,200 acres in
   any one State if this is a geothermal lease; and (d) All parties holding an
   interest in the assignment are otherwise in compliance with the regulations
   (43 CFR Group 3100 or 3200) and the authorizing Acts.

3. Assignee's signature to this assignment constitutes acceptance of all
   applicable terms, conditions, stipulations and restrictions pertaining to the
   lease described herein.

For oil and gas assignments, the obligation to pay overriding royalties, payment
out of production, carried interests, net profit interests, or such similar
payments or interests created herein, which when added to overriding royalties
or payments out of production or other similar interests or payments previously
created, may be suspended by the Secretary at any time upon a determination that
the excess constitutes a burden on lease operations in accordance with 43 CFR
3103.

For geothermal assignments, an overriding royalty may not be less than one-
fourth (1/4) of one percent of the value of output, nor greater than 50 percent
of the rate of royalty due to the United States when this assignment is added to
all previously created overriding royalties (43 CFR 3241).

I certify that the statements made herein by me are true, complete, and correct
to the best of my knowledge and belief and are made in good faith.
