GEOTHERMAL RESOURCES LEASE

(Minersville Land and LivestockSurface Lands Retained by

Lessor)

THIS GEOTHERMAL RESOURCES LEASE (Lease), entered into this 25thday of September, 2007, by and between MINERSVILLE LAND AND LIVESTOCK COMPANY, a Utah corporation (collectively, Lessor), and INTERMOUNTAIN
RENEWABLE POWER, LLC, a Delaware limited liability company (Lessee).

1. INTEREST GRANTED:

The interest granted hereunder is in the geothermal resources estate, and Lessor shall retain the surface estate. In addition, the parties believe that
the Lessor holds an undivided 75% interest in the geothermal resources estate, with the remaining 25% (the 25% Interest) held by the successors and assigns of Superior Oil Company (per grant from RonaldG.Wilcox). Lessee
shall be responsible for coordinating with the holder of the 25% Interest in leasing such interest. The Production Royalties payable under Section 3(b) shall be proportionately reduced to the extent that Lessor holds less than the full interest
in the geothermal estate (for example, 75% of the [***] and [***] Production Royalties specified in Section 3(b) (i) ) . In the event Lessor re-acquires the 25% Interest, such interest shall be deemed to be leased to Lessee hereunder and
the Production Royalties increased accordingly. In consideration of the covenants and agreements contained herein, Lessor hereby grants and leases to Lessee the exclusive right and privilege to drill for, extract, produce, remove, utilize, sell,
and dispose of all forms of thermal energy and other associated geothermal resources including without limitation:

(1) all products of
geothermal processes, including the natural heat of the earth, and the energy, in whatever form, including pressure, present in, resulting from, created by, or which may be extracted from that natural heat, directly or through a material medium
together with indigenous steam, hot water and hot brines; (2) steam and other gases, hot water and hot brines resulting from water, gas, or other fluids, including water and steam naturally present in a geothermal system, artificially
introduced into subsurface formations to serve as a heat transfer medium; (3) natural heat of the earth and the energy associated with that natural heat, and pressure; and (4) all dissolved or entrained minerals, substances or by-products
(Substances) that may be obtained from the medium used to transfer that heat, but excluding hydrocarbons and helium (collectively Geothermal Resources, which includes Substances except as necessary to separately determine
royalties as provided in Section 3),

in, on, under, adjacent to, or associated with those certain parcels of property (the Premises)
consisting of approximately eleven thousand two hundred and ninety-four (11,294) acres, as more particularly described as follows :

All that certain real property consisting of approximately 11,294 acres located in Beaver County, State of Utah, more particularly described on Exhibit A attached hereto and incorporated herein by reference, including
all interests in said Premises now owned or hereafter acquired, together with:

(a) Exploration. The exclusive right
to conduct within the leased area geological and geophysical exploration for Geothermal Resources;



---

(b) Development and Operations. Subject to the approval of Lessor as to
location, not to be unreasonably withheld, the right to construct or erect and to use, operate, and maintain on the Premises, together with ingress and egress thereupon, all wells, pumps, pipes, pipe lines, buildings, plants, sumps, brine pits,
reservoirs, tanks, waterworks, pumping stations, roads, electric power generating plants, transmission lines, industrial facilities, telephone lines, and such other works and structures and to use so much of the surface of the land that may be
reasonably necessary or convenient for the exploration, development, production, utilization, transportation, and processing of Geothermal Resources or for the full enjoyment of the rights granted by this Lease, subject to applicable laws and
regulations;

(c) Water. The non-exclusive right to drill water wells, and the exclusive right to drill wells into
Geothermal Resources that contain water, steam and brines, in accordance with Utah statutory laws within the Premises and to use the water produced therefrom for operations and activities hereunder, free of costs, provided that such drilling and
development is conducted in such away that they do not unreasonably interfere with Lessors activities on the Premises; and further that Lessor will use its best efforts to cooperate with Lessee to apply for, appropriate and use water
produced from the Premises (or lands pooled or unitized therewith) in furtherance of developing and conducting operations on the Premises (or lands pooled or unitized therewith). Lessor and Lessee shall evaluate the possibility of providing some
water from geothermal operations for use in livestock watering.

(d) Injection. The right, without the payment of
royalties hereunder, to inject or reinject into the leased lands geothermal resources, condensates, gas, treated wastewater or other fluids to the extent that such resources, condensates and fluids are necessary or convenient for operation under
this Lease in the recovery or processing of Geothermal Resources, including to maintain or increase pressure or production or to conduct tests.

(e) Directional Drilling. The right to locate a well or wells on the surface of said land and to directional or slant drill said well or wells into, under, across and through the Premises and into and under
other lands in the vicinity of the Premises, together with the right to repair, re-drill, deepen, maintain, inject in, rework and operate or abandon such well or wells for the production of Geothermal Resources from such other lands together with
the right to develop water from said land for any of Lessees operations; together with the right to construct, erect, maintain, use, operate, replace, and remove all power generation facilities, transmission facilities, pipe lines, telephone
lines, tanks, machinery, and other facilities; together with all other rights necessary or convenient for Lessees operations under this subsection including rights of way for passage over and upon and across and ingress and egress to and from
said Premises; together with the right and easement to continue to use such items, as well as rights of way and/or easements appurtenant thereto, so long as Lessee

until such use is permanently discontinued. Upon the written request of Lessee, Lessor agrees to provide separate easements or rights-of-ways, in form sufficient for recording in the applicable county real property records, to evidence such surface
rights in this Section l(e). If the Lessor fails to provide such written easements within thirty (30) days of Lessees written request, Lessor authorizes Lessee to unilaterally prepare and execute such easements and record the same in the
applicable countys real property records. Should Lessee elect to unilaterally execute such easements, the nature, scope and duration of such easements as described in the executed document shall accurately and reasonably reflect the existing
uses in relation to Lessees surface and underground operations on the Premises (or on lands pooled and unitized therewith).

accruing hereunder shall be paid to Lessor only in the same proportions which Lessors interest bears to a one hundred per cent interest in the leased
Premises. Notwithstanding the foregoing, should Lessor hereafter acquire any additional right, title or interest in or to the leased Premises, it shall be subject to the provisions hereof to the same extent as if owned by the Lessor at the date
hereof, and any increase in payments of money hereunder necessitated thereby shall commence with the payment next following receipt by Lessee of satisfactory evidence of Lessors acquisition of such additional interest.

4. TAXES AND ASSESSMENTS:

(a)
Taxes and Improvements. Lessee shall pay all taxes levied and assessed against Lessees leasehold interest in the Premises. Lessee shall pay all taxes levied and assessed against all structures, improvements and personal property placed
upon the Premises by Lessee. Lessor shall pay all taxes levied and assessed against the Premises as such and against any rights thereto not covered by the Lease and shall pay all taxes levied and assessed against all structures and improvements
placed on the Premises by Lessor. Any increase in taxes arising from geothermal operations on the Premises shall be paid by Lessee.

Geothermal Resources from or allocated to the Premises, and to pay all of any other taxes assessed against the Premises, whether the same are assessed to Lessor or Lessee or otherwise. Lessor shall pay all of its tax obligations within thirty
(30) days of when due and shall provide Lessee, upon request, with evidence of such payment. Lessor grants Lessee the right, but not the obligation, to pay any of Lessors tax obligations hereunder, and to offset the amount of such
payments made on Lessors behalf against any amounts due to Lessor under this Lease, with interest at [***].

5. PROTECTION OF
SURFACE; LAWS; LIENS; EQUIPMENT

(a) Protection of Surface; Compensation for Damage. Lessee agrees to conduct its activities in a
good and workmanlike manner and use reasonable care at all times in all of Lessees operations on the Premises to prevent injury or damage to cattle, livestock, buildings, water rights, water diversion works, ditches, tanks and water wells or
other property of the Lessor located thereon; and Lessee agrees to repair, mitigate or pay the Lessor the fair market value (as determined by an independent third-party appraiser) for all damages to the cattle, crops, buildings, livestock,
fences, water rights, water diversions, ditches, tanks, water, water wells and other property of the Lessor situated on the surface of the Premises resulting from Lessees operations on the Premises. Lessee also agrees that all damages to pipe
and equipment caused by cattle shall be the responsibility of Lessee.

(b) Compliance with Laws. Lessor and Lessee each agree
that they will conduct all activities and operations associated with the Premises and with this Lease at all times in accordance with applicable federal, state and local laws, rules and regulations.



6



---

(c) Liens. All labor to be performed and material to be furnished in the operations under this
Lease shall be at the sole cost and expense of Lessee, and Lessee shall hold Lessor free and harmless from liability thereunder. Lessee and Lessor shall each keep the Premises fully protected against any and all liens of every character arising from
or connected with their individual operations on the Premises. Lessor agrees not to permit any mortgage or other lien to be placed on the property that would affect or purport to affect or supersede Lessees interest under this Lease. Lessor
acknowledges and agrees that Lessee, in order to pursue its activities hereunder may utilize various project, equipment and other financing options and as part of such financings Lessee may assign its interests under this Lease (whether for security
purposes or as a full and complete assignment). To the extent the Premises are currently encumbered by a mortgage, deed of trust, or other lien created by Lessor, Lessor shall use its best efforts to obtain a subordination, in recordable form, of
such encumbrance to this Lease.

(d) Reclamation. Within six (6) months after abandonment of any well, including those
abandonments resulting from termination of this Lease, Lessee shall remove all machinery, material, and structures used in connection with said well and not used in its other operations, if any, on the Premises, and shall fill in and level off all
excavations, pits, or other alterations to the surface of the Premises caused in connection with said well, and, insofar as practical, shall, restore the Premises and the means of ingress and egress in compliance with all requirements of applicable
reclamation laws and regulations, except reasonable wear and tear, acts of nature and conditions beyond the control of Lessee.

(e)
Equipment and Improvements. Lessor agrees that Lessee shall retain ownership of, and can remove at any time, any and all improvements, equipment, fixtures and property of any kind brought onto or attached or affixed to the Premises, including
all well casings, pipes, power generation equipment, buildings, transmission lines and all other equipment or property of any kind, regardless of whether such property is considered realty or personalty for state law or other purposes.

6. COMMINGLING, POOLING, AND UNITIZATION:

(a) Commingling. Lessee shall have the right to commingle (for purposes of storing, transporting, handling, unitizing, selling or processing) Geothermal Resources produced or extracted from the Premises (and lands pooled, unitized or
combined therewith), with similar substances produced or extracted from other lands or units. In the event of such commingling, Lessee shall meter, gauge, or measure, according to prevalent industry standards, the production from the Premises at the
well head, or from the unit or units including the leased land or other units or lands, as applicable, and compute and pay Lessors royalty attributable to Lessors land on the basis of such production as so determined or allocated.

(b) Pooling and Unitization. Lessee may, without notice to or consent from Lessor, as a recurring right for drilling, development
or operating purposes, pool, unitize, or otherwise combine all or part of the Premises into a unit (whether federal or voluntary contractual unit) with any other land or lands (whether held by Lessee or others), whether or not adjacent or
contiguous,



7



---

which Lessee desires to develop or operate (singly or in combination with others) as a unit. The execution by Lessee of any unit agreement, unit operating
agreement or other documents necessary to such pooling or unitization shall be binding on the Premises and Lessors current and future interests therein. Lessee shall provide Lessor courtesy notice of any pooling or unitization of the Premises.
Any well (whether or not Lessees well) commenced, drilled, drilling and/or producing or being capable of producing in any part of such unit shall for all purposes of this Lease be deemed a well commenced, drilled, drilling and/or producing on
the Premises, and the Lessee shall have the same rights and obligations with respect thereto and the drilling and producing operations upon the lands from time to time included within any such unit as Lessee would have if such lands constituted the
Premises leased hereunder; provided, however, that notwithstanding this or any other provision or provisions of this Lease to the contrary:

(i) Production as to which a royalty is payable from any such wells or wells drilled upon any such unit, whether located on the Premises or other lands, shall be allocated to the Premises in the proportion that the
acreage of the leased land in such unit bears to the total acreage of such unit. Such allocated portion thereof shall for all purposes be considered as having been produced from the Premises, and the royalty, payable under this Lease with respect to
the leased land in such unit shall be payable only upon that proportion of production so allocated, and

(ii) If taxes of
any kind are levied or assessed (other than taxes on the surface and on Lessors improvements), any portion of which is chargeable to Lessor under the provisions of this Lease, then the share of such taxes to be borne by Lessor shall be in
proportion to the share of the production from such unit allocated to the Premises.

(iii) Lessor hereby grants Lessee (or
the consents to the assignment of such rights from Lessee to any unit operator) the right to use of the surface of the Premises in support of unit operations, including all the surface uses enumerated in Section 1 above. In the event the
Premises, or any portion thereof, are later removed from the unit by any contraction of the Unit Area, all such existing surface uses of the Premises in support of unit operations shall continue in force and effect, and Lessor agrees to provide
Lessee or the unit operator with written easements, rights-of-way, licenses or such other acceptable surface use grants, in recordable form, to evidence such existing surface uses in support of unit operations. If the Lessor fails to provide such
written easements within thirty (30) days of Lessees written request, Lessor authorizes Lessee to unilaterally prepare and execute such easements and record the same in the applicable countys real property records. Should Lessee
elect to unilaterally execute such easements, the nature, scope and duration of such easements as described in the executed document shall accurately and reasonably reflect the existing uses in relation to Lessees surface and underground
operations on the Premises (or on lands pooled and unitized therewith).

7. RESERVATIONS TO LESSOR:

The following rights (to the extent owned by Lessor) are reserved to Lessor, provided such rights and activities do not interfere with Lessees
exploration, development, production or other operations, activities or rights hereunder on the Premises or any Unit Area:

(i) Surface Use - the right to conduct ranching operations, or sell or otherwise dispose of the surface of the Premises (subject to this Lease) in a lawful manner. Any specific restrictions on the prospective use of the Premises by
Lessee, as a result of specific surface needs of the Lessor, may be set forth in an Appendix to this Lease.

(ii) Mineral
Rights - the right to extract minerals, hydrocarbons, and helium (other than Substances) from the Premises, subject to the following covenants and restrictions:

Notwithstanding the reservation of mineral rights to the Lessor, Lessor and Lessee acknowledge that Lessee shall make substantial investments in exploring for and developing geothermal resources on the Premises (or
Unit Area). Lessor hereby covenants and agrees, on behalf of itself, its successors and assigns, including any future lessee of any mineral lease on the Premises, that the rights of Lessee under this Lease shall be and remain superior to the
rights of Lessor (or its lessees, successors or assigns) in the reserved mineral estate. To the extent that Lessor (or its lessees, successors or assigns; as applicable, the Mineral Rights Holder) intend to explore for, develop, extract,
transport or process minerals on the Premises, such Mineral Rights Holder must enter into a joint development agreement, on such form provided by and acceptable to Lessee, in its sole and absolute discretion, which shall provide for the cooperation
and coordination of joint development of the mineral estate and the geothermal resources estate; provided that all conflicts between such surface or subsurface uses of the Premises shall be resolved in favor of the Lessee and its rights hereunder.
Lessor further covenants and agrees that before entering into any mineral lease on all or any part of the Premises, Lessor shall provide Lessee with ten (10) days prior written notice of such proposed mineral lease, the terms and provisions of
such proposed mineral lease, and the party requesting the mineral lease as lessee. Lessee reserves the right to propose a specific addendum to such proposed mineral lease to address the operational needs of the Lessee, and the agreement of such
mineral lessee to the requirements of Lessee shall be a condition to the execution and recordation of any mineral lease. Any mineral lease shall expressly reference this paragraph and the dominance of the rights under this Lease as to the mineral
estate, and Lessor agrees that a reference to the subordination of the mineral estate to the geothermal estate leased hereunder may be included in any recorded memorandum of this Lease.

8. DEFAULT AND TERMINATION; SURRENDER:

(a) Default by Lessee. Whenever the Lessee fails to comply with any of the material terms and provisions of this Lease, and does not commence to remedy such failure within forty-five (45) days after receipt of written notice
from Lessor, the Lessor may (a) suspend operations until the requested action is taken to correct the noncompliance, or (b) cancel this Lease by delivering written



9



---

notice of its intent to do so to Lessee; provided, however, that if there is a bona fide dispute as to the amount due in the case of a payment dispute and
all undisputed amounts are paid, said forty-five (45) day period shall be extended until five (5) days after such dispute is settled by final court decree or agreement. The following property shall be excepted from any Lease termination
hereunder as a result of default: (a) each and any well then capable of producing in commercial quantities the substances covered by this Lease, and in respect to which Lessee is not in default, plus an area of 20 acres surrounding such well;
and (b) rights of way and easements across lands subject to such Lease termination, which rights of way and easements are necessary for conducting Lessees operations on or in the vicinity of the lands retained (or any Unit Area), with
respect to which Lessee is not in default, including sites for electric generating units.

(b) Surrender. Lessee shall have the
right, in its sole discretion and at any time, to surrender all or any portions of the Premises it does not intend to utilize. In such case, Lessee shall execute and record a quit claim deed as to such surrendered portions, and Lessee shall thereby
be relieved of all obligations as to the acreage so surrendered.

9. CONDEMNATION:

Eminent domain proceedings resulting in the condemnation of a part of the Premises leased herein, but leaving the remaining Premises reasonably usable by
Lessee for the purposes of the activities described herein, will not terminate this Lease unless Lessee consents in writing to such termination. The effect of any such partial condemnation will be to terminate the Lease as to the portion of the
Premises condemned, and the Lease of the remainder of the Premises shall remain intact. To the extent that all or a portion of the surface estate of the Premises is condemned, but the geothermal estate is not condemned, Lessee may retain all such
acreage that it is capable of continuing to operate, on a lease basis or unit basis, as determined in its sole and absolute discretion. Lessee is authorized to unilaterally record notice of the status of such retained acreage after any condemnation.
To the extent that the geothermal estate is of necessity condemned as part of such condemnation proceeding or request, Lessee shall be granted notice of such condemnation, the right to participate in and negotiate damages for loss of such geothermal
estate, and all proceeds from that portion of any condemnation award that pertains to the loss of the geothermal estate shall be paid to Lessee.

10. ASSIGNMENTS, SUBLEASES, DIVIDED INTERESTS:

(a) Assignment and Sublease. Lessee shall have the absolute right to
sell, assign or sublease all or any portion of its interest or right in and to this Lease and/or the Premises; these rights shall include, without limitation, the right to pledge, assign, mortgage, or otherwise collateralize the Lease to any
affiliate of Lessee and/or any party for the purpose of financing or tax structuring. Lessor shall have the right to sell or assign its interest or right in and to this Lease and/or the Premises with the prior written consent of Lessee, which shall
not be unreasonably withheld.

(b) Divided Interests. In the event of assignment (by operation of law or otherwise) of the Lease as
to a segregated portion of the Premises, or if it is otherwise determined that more than one party holds the leasehold interest hereunder, payments due the Lessor hereunder shall be apportionable among the several leasehold owners according to the
surface area of each of their respective



10



---

leaseholds (unless undivided ownership is otherwise set forth expressly in recorded documents), and default in such payment by one or more of such leasehold
owners shall in no way affect the right of any other leasehold owner hereunder. In the event of any uncertainty or dispute as to the parties entitled to such payment, Lessee shall be entitled, in its sole discretion, to discharge its payment
obligation by making such payments into a third party escrow, court escrow, or such other method as Lessee reasonably determines. Lessors successors and assigns agree to execute and record any stipulations and cross-conveyances as may be
necessary to establish of record the ownership of segregated or fractional interests in the Premises. Lessor shall provide fifteen (15) days prior written notice of any proposed sale of the surface estate only on the Premises (with the
reservation by Lessor of the geothermal or other subsurface estates).

11. FORCE MAJEURE:

Lessees obligations hereunder save and except payment of annual rentals set forth in Section 3(a) above shall be suspended, and the term of the
Lease and the period for removal of Lessees property in the event of termination shall be extended while Lessee is prevented from complying therewith by: strikes; lockouts; riots; action of the elements, including but not limited to fire,
explosion, flood, volcanic activity, earthquakes, or tidal waves; accidents; delays in transportation; inability to secure labor or materials in the open market; laws, rules or regulations of any Federal, State, County, Municipal or other
governmental agency, authority or representative having jurisdiction, including failure or delay in issuance of necessary permits or approvals; war (whether declared or undeclared including terrorist acts); acts of God; litigation or administrative
proceedings affecting title to lands covered hereby or operations thereon; inability to secure or absence of a market for commercial sale of Substances and/or Geothermal Resources, or any of them, produced from the Premises or of derivatives
developed by Lessee therefrom; or by other matters or conditions beyond the reasonable control of Lessee, whether or not similar to the conditions or matters in this Section specifically enumerated (Force Majeure).

to elect to match such Top Lease Offer. If Lessee elects to match such Top Lease Offer, it shall provide written notice of such election within such thirty (30) day period, which election shall constitute a binding obligation to match such Top
Lease Offer; provided however that Lessee shall not be obligated to pay any upfront rental, bonus or other consideration that, by the terms of the Top Lease Offer are required to be paid at execution, until this Lease shall actually terminate and
expire by its terms (or be surrendered by Lessee).
