 GEOTHERMAL RESOURCES LEASE 
 (Minersville Land and Livestock–Surface Lands Retained by 
 Lessor) 
 THIS GEOTHERMAL RESOURCES LEASE (“Lease”), entered into this 25th day 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 Ronald G. 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 a way 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 

  

 2 

 
utilizes Geothermal Resources from such other land in the vicinity of the Premises, notwithstanding the expiration, termination or forfeiture of this Lease,
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). 
 2.
TERM: 
 (a) Initial Term, As Extended. This Lease shall have a term of TEN (10) years from the date first set forth above
(the “Initial Term”) and shall continue for so long thereafter as: 
 (i) Lessee is extracting or drilling for
Geothermal Resources on the Premises (or lands pooled or unitized with the Premises), working with reasonable diligence, allowing not more than TWENTY-FOUR (24) months between the completion or abandonment of one site/well and the exploration
and/or commencement of operations for the next; 
 (ii) Geothermal Resources are being produced or generated from the Premises
(or lands pooled or unitized with the Premises) in commercial quantities or steps are being taken to develop the Premises in such a way as to produce or generate from the land commercial quantities; 
 (iii) Remedial Operations are being continuously conducted on the Premises (or lands pooled or unitized with the Premises); 
 (iv) Drilling operations, commercial production of Geothermal Resources, or Remedial Operations are suspended or excused under the Force
Majeure or other provisions of this Lease; or 
 (vi) this Lease is otherwise extended by its terms. 
 “Remedial Operations” means reworking, redrilling, cleaning, testing, and the repair and replacement of wells and facilities for the production or use of
Geothermal Resources. Remedial Operations shall be deemed continuous so long as such operations do not cease for a period of more than two (2) consecutive years. Production in “commercial quantities” shall mean production in such
quantities of Geothermal Resources, produced, sold, or used, or capable of being produced, sold, or used, either from the Premises or lands pooled or unitized therewith, the value of which, after deducting Lessor’s royalty hereunder and
Lessee’s normal operating costs will provide to Lessee a return of such costs.

Resources, Lessor shall pay to Lessee the sum of [***]. On or before each anniversary date hereafter while the Lease is in force, Lessee agrees to pay to Lessor as rental for the next ensuing year the sum of [***] per acre; provided, however, that
rentals paid to Lessor under this subsection shall apply toward or be credited to royalties payable or to become payable on actual production (if any) under Section 3(b) for any year such rentals are paid. To the extent a portion of the
original acreage of this Lease is lost or surrendered by the Lessee, the Annual Rental shall be reduced proportionately. 
 (b) Production
Royalties. Subject to Section 11 below, and subject to proportionate reduction as described in Section 1 and in Section 3(d), Lessee shall pay to Lessor a royalty out of the proceeds received by Lessee from the sale of Geothermal
Resources or Substances produced from the Premises, or allocated to the Premises as provided in Sections 6 and/or 10(b) as follows: 
 (i)
Power Generation. If Lessee utilizes Geothermal Resources to generate and sell electric power, a royalty of [***] of the gross proceeds of the sale of said electric power for the first [***] years from the first sale of electricity and
[***] thereafter, in each case less Deductible Costs (as defined in Section 3(b) (vi)); 
 (ii) Sale of Substances. If Lessee
sells any Substances as such, a royalty of [***] of the gross proceeds of the sale of said Substances for the first [***] years from the first sale of Substances and [***] thereafter, in each case less Deductible Costs; 
 (iii) Sale of By-Products. If Lessee treats or processes or causes to be processed, any Substances and/or Geothermal Resources for the extraction
or manufacture therefrom of any by-products, and sells any by-products, a gross royalty of [***] of the proceeds from the sale by Lessee of said by-products, less Deductible Costs; 
 (iv) Other Commercial. If Lessee uses Geothermal Resources and/or Substances at a commercial facility other than an electric power generating

costs and of any transmission or transportation to the point of use if used off the Premises or off of any area pooled or unitized with the Premises (the “Unit Area”), as the case may be. 
  

 4 

 (v) Internal Use. Lessee may use, free of royalty, Substances, Geothermal Resources, electric
power and by-products developed from the Premises for all operations hereunder (or operations within any Unit Area), and Lessee shall not be required to account to Lessor for or pay royalty on any Substances, Geothermal Resources, electric power or
by-products reasonably lost or consumed in operations hereunder. 
 (vi) Deductible Costs. For purposes of Sections
3(b)(i)-(iii) above, “Deductible Costs” shall mean: 
 (A) any sales, excise or other taxes imposed on the sale of any said
electric power, Substances, or by-products, as the case may be, so sold or which are required to be included in or added to the sales price thereof or paid by the seller; and 
 (B) any cost to Lessee of any transmission or transportation to the point of sale of any of said electric power, Substances or by-products so sold, if
sold off the Premises or the Unit Area, as the case may be; and 
 (C) assuming Lessee does not use electricity generated from the
geothermal plant(s) for such requirements, the reasonable and standard cost of any electricity purchased by Lessee from unaffiliated third parties to operate the geothermal well field pumps or serve other parasitic loads of the geothermal gathering
field or the generating plant(s). 
 (vii) Payment. Lessee shall pay Lessor, on or before the last day of each and every calendar
month, the above production royalties accrued and payable for the preceding calendar month (“Payment Date”), and shall deliver to Lessor a statement setting forth the basis for the determination of such royalty. Notwithstanding anything to
the contrary, Lessor agrees that the Payment Date shall be adjusted to coincide with billing procedures set forth in any applicable power purchase agreements, whether monthly, bi-monthly, quarterly, or otherwise. 
 (c) Directional Drilling and Other Surface Use Rentals. If Lessee exercises the directional drilling rights granted in Section 1(e), or if
Lessee is using part of the surface of the Premises for unit or other operations and the Lease is terminated or surrendered (including without limitation, in the event the Lease is committed to a unit but is later excluded from such unit by
contraction of the unit or any participation area) Lessor shall not be entitled to any production royalties under Section 3(b), unless, and only to the extent that, such activity constitutes a commingling, pooling or unitization utilizing
Geothermal Resources from the Premises under Section 6. In lieu of any other compensation, Lessee shall pay to Lessor an annual rental computed at the rate of [***] per acre for each surface acre of the Premises being exclusively occupied by
Lessee pursuant to such grant under Section 1(e) and [***] per rod for any roads, utility lines, pipelines, or other linear items associated therewith. 
 (d) Proportionate Reduction. In the event Lessor at the time of making this Lease owns an interest in the leased Premises that is less than one hundred per cent of the total rights in the geothermal estate,
then the rentals, royalties and other consideration 

  

 5 

 
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. 
 (b) Severance Taxes on Lessor’s Royalties. Lessor agrees to pay any and all taxes assessed upon Lessor’s royalty proceeds for any Substances and/or Geothermal Resources produced and sold by Lessee from the Premises and ad
valorem taxes on Substances and/or Geothermal Resources together with the same share of all severance, production, net proceeds and license taxes or other taxes or assessments levied or assessed on account of the production of Substances and/or
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). 
  

 8 

 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”).

 STANDARD TERMS & CONDITIONS 
 INVOICING SCHEDULE 
 BUYER agrees to pay to UTCP the Total Contract Price for the equipment and services
described in this Agreement, based on the following invoicing schedule: 
  

	 	•	 	 [***]% of the Total Contract Price shall be invoiced by UTCP upon BUYER receiving funding from or one or more affiliates of Merrill Lynch, Pierce, Fenner and
Smith., Inc. (the “Lender”) under the terms of that certain Credit Agreement (the “Credit Agreement”) between BUYER and Lender dated as of August 31, 2008 (the “Funding Date”) and shall then be
due and payable by BUYER to UTCP within five business days of the Funding Date (the “Funding Payment”) in accordance with the payment terms below; 

  

	 	•	 	 [***]% of the Total Contract Price shall be invoiced by UTCP upon delivery of the first 50% of the Equipment to the Destination and shall then be due and payable by
BUYER to UTCP within thirty (30) business days of the date of the invoice in accordance with the payment terms below (the “First Delivery Payment”); 

  

	 	•	 	 [***]% of the Total Contract Price shall be invoiced by UTCP upon delivery of the last unit of Equipment to the Destination and shall then be due and payable by
BUYER to UTCP within thirty (30) business days of the date of the invoice in accordance with the payment terms below (the “Second Delivery Payment”); 

  

	 	•	 	 Subject to any Mechanical Completion Delay Penalties, [***] of the Total Contract Price shall be invoiced by UTCP upon the occurrence of Mechanical Completion (as
hereinafter defined) and shall then be due and payable by BUYER to UTCP within thirty (30) business days of the date of the invoice in accordance with the payment and other terms below (the “Mechanical Completion Payment”). For
purposes of this Agreement, “Mechanical Completion” means the date upon which (i) BUYER’s design, engineering, procurement, permitting, construction (except for punch-list items) and permanent installation of the
geothermal electricity plant that incorporates the Equipment (the “Facility”) is complete, the Commissioning Test shall have been completed for each unit of Equipment and there shall have been a Successful Commissioning Test as
defined in Exhibit D-1, (ii) BUYER is in receipt of applicable turnover packages, (iii) the Facility is capable of operating safely in accordance with applicable laws and prudent electric power industry practices.

  

	 	•	 	 Subject to any Performance Penalties, [***] of the Total Contract Price shall be invoiced by UTCP upon the occurrence of a Successful Performance Test (as
hereinafter defined) and shall then be due and payable by BUYER to UTCP within thirty (30) business days of the date of the invoice in accordance with the payment and other terms below (the “Successful Performance Test
Payment”). For purposes of this Agreement, “Performance Test” means a performance test conducted by or at the direction of BUYER and in accordance with the methodologies set forth in Exhibit D-2 hereto. A
“Successful Performance Test” is a Performance Test that demonstrates Facility net electrical output of not less than [***] of the performance benchmark of 10.35 MW (the “Performance Benchmark”) for 240 consecutive hours
(the “Test Period”), provided, however, that if the total Facility hot water resource flow rate (“Total Facility Flow”) is less than the Aggregate Corrected Flow (as such term is defined in Exhibit D-1), the
Performance Benchmark shall be adjusted in accordance with the following formula: 10.35 MW * (Total Facility Flow / Aggregate Corrected Flow) (the “Adjusted Performance Benchmark”). Notwithstanding the foregoing, the Performance
Test shall be deemed a Successful Performance Test for purposes of determining payments and for calculating Performance Penalties (defined below) under this Agreement if the result of the Performance Test meets the criteria set forth in this
paragraph with the Performance Benchmark set at 10.0 MW (the “Contract Performance Benchmark”). 

 The Funding Payment is
meant to cover the cost of lead-time sourcing, product support and equipment processing, and is non-refundable. In the event UTCP has not received the Funding Payment, the First Delivery Payment or the Second Delivery Payment, in full, by their
respective due dates then UTCP’s Delivery Date obligations under this Agreement shall be extended on a day-for-day basis for each day that the Funding Payment, the First Delivery Payment or the Second Delivery Payment, as the case may be, is
past due. 
 PAYMENT TERMS 
 All payments made to
UTCP shall be made in U.S. dollar funds by wire transfer or check in the required remittance amount without discount to a U.S. bank designated by UTCP for credit to UTCP’s account. If payment is made by check BUYER shall send the check to:

 Swift # (International): [***] 
 Each payment will accrue
interest from the date it is invoiced until the date it is received by UTCP, at a rate of 1.5% per month. In no event shall any such interest be deemed to be a penalty but shall be solely construed as an administrative charge to UTCP arising
out of BUYER’s late payment. BUYER shall reimburse UTCP for any expenses, including reasonable attorneys’ fees, incurred in collecting any overdue payments, and in no event shall the payment hereunder exceed any applicable federal or state
usury laws. 
 UTCP shall submit invoices for payment to BUYER at the address incorporated under the section herein entitled NOTICES, if any, or as otherwise
directed in writing by BUYER. 
 The prices set forth in this Agreement are firm, provided that if BUYER delays delivery of the units of Equipment (as
defined in Exhibit A) from the applicable agreed-upon Delivery Dates, then BUYER agrees to pay UTCP any increased costs that it incurs from third parties based on such delay, including any rerouting or other shipping costs, any storage and
rigging fees, and any price increases from suppliers of the units of Equipment being purchased under this Agreement or any services under this Agreement that, in all cases, are the direct result of such delay. 
 SECURITY INTEREST 
 BUYER hereby grants to UTCP a continuing
second priority security interest in and lien upon all of BUYER’s right, title and interest in and to the Equipment (the “Collateral”) to secure BUYER’s payment of the Total Contract Price; provided however that if (i) BUYER
has failed to pay an amount that is due under this Agreement, and (ii) BUYER has repaid in full all amounts outstanding under the Credit Agreement, then BUYER shall grant to UTCP a continuing first priority security interest in and lien upon
the Collateral. Upon payment in full of the Total Contract Price (subject to adjustments thereto for Performance Penalties or Mechanical Completion Delay Penalties pursuant hereto) the security interest and lien of this Agreement shall automatically
terminate and UTCP shall take such actions (at UTCP’s sole cost and expense) as are reasonably requested by BUYER to release the Collateral from the security interest and lien granted by this Agreement. The validity and enforceability of the
security interest and lien created pursuant to this Agreement shall be subject to UTCP entering into a subordination agreement with the Lender containing subordination and other terms and conditions satisfactory to the Lender (the
“Subordination Agreement”). 
 For as long as the Total Contract Price remains unpaid, in whole or in part, BUYER agrees to provide UTCP with
prompt written notice of the occurrence of any Event of Default (as hereinafter defined). In addition, BUYER will maintain insurance covering the Collateral as is customary for businesses similar to the business of BUYER and will promptly name UTCP
as loss payee, as its interests may appear, of any insurance now or hereafter covering the Collateral. BUYER will pay promptly when due all taxes and assessments on the Collateral or for its use or operation, except for taxes and assessments which
are being contested in good faith. Upon any failure of BUYER to pay any such taxes and assessments within five business days after notice from UTCP, UTCP may at its option discharge any taxes (which are not being contested by BUYER) to which any
Collateral is at any time subject. In addition, upon the failure of BUYER to do so, UTCP may purchase insurance on any Collateral and pay such amounts as may be reasonably necessary for the repair, maintenance or preservation thereof. BUYER agrees
to reimburse UTCP on demand for any payments or expenses incurred by UTCP pursuant to the foregoing authorizations. BUYER will promptly execute and deliver to UTCP such financing statements, certificates, notices and other documents or instruments
as may be necessary to enable UTCP to perfect or from time to time perfect, renew or continue the security interest granted herein. BUYER hereby authorizes UTCP to take all action (including, without limitation, the filing of any Uniform Commercial
Code Financing Statements or amendments thereto without the signature of BUYER) that UTCP may deem necessary or desirable to perfect or otherwise protect the security interest described hereunder. 
 Each of the following shall constitute an event of default (an “Event of Default”) hereunder: (a) BUYER becoming insolvent, making an assignment
for the benefit of creditors or making or sending a notice of intended bulk transfer, or if a committee of creditors is appointed for, or any petition or proceeding for any relief under any bankruptcy, reorganization, arrangement, insolvency,
readjustment of debt, receivership, liquidation or dissolution law or statute now or hereinafter in effect (whether at law or in equity) is filed or commenced by or against BUYER or any of its properties or a receiver or trustee is appointed for
BUYER or any of its properties and is not released or terminated within 120 days of such filing or appointment, as the case may be; (b) any merger, consolidation or other business combination involving BUYER or the sale of all or substantially
all of the assets of BUYER where the surviving entity fails to assume all the obligations of BUYER under this Agreement by operation of law or pursuant to an agreement reasonably satisfactory to UTCP; or (c) the failure to pay any installment
of the Total Contract Price pursuing to the Invoicing Schedule, in whole or in part, and after taking into account all adjustments thereto for Mechanical Completion Delay Penalties and Performance Penalties, within thirty (30) calendar days
after notice by UTCP to Buyer of such failure; 
 Upon the occurrence of any Event of Default such default not having been remedied within 30 days of its
occurrence or waived by UTCP, subject to the terms of the Subordination Agreement, UTCP shall have the following rights and remedies: (i) all rights and remedies provided by law, including, without limitation, those provided by the Uniform
Commercial Code as in effect in the State of Connecticut from time to time (the “UCC”); and (ii) the right to take possession of the Collateral and in addition thereto, the right to enter upon any premises on which the
Collateral or any part thereof may be situated, without notice, and remove the same therefrom. All rights and remedies available to UTCP pursuant to the provisions of this Agreement, applicable law and otherwise are cumulative, not exclusive, and
are enforceable alternatively, successively and/or concurrently by UTCP.

 MECHANICAL COMPLETION DELAY PENALTIES 
 The full Mechanical Completion Payment amount shall only be due and payable by BUYER to UTCP if Mechanical Completion occurs on or prior to the Guaranteed Mechanical Completion Date (as hereinafter defined). For
purposes of this Agreement, “Guaranteed Mechanical Completion Date” means December 1, 2008; provided that UTCP agrees that it shall use commercially reasonable efforts to reach Mechanical Completion as soon as possible
following the Access Date (defined below). In the event that Mechanical Completion does not occur on or prior to the Guaranteed Mechanical Completion Date, the Mechanical Completion Payment amount shall be reduced by [***] for each day that
Mechanical Completion is not achieved by the Guaranteed Mechanical Completion Date (the “Mechanical Completion Delay Penalties”). Should Buyer not incur any penalties (including, but not limited to, required prepayments to its
Lenders under the Credit Agreement or to its investors under the Limited Liability Company Agreement of BUYER) as a result of Mechanical Completion not being achieved by December 31, 2008, then any accrued Mechanical Completion Delay Penalties
shall be forgiven. In the event that Mechanical Completion is not complete by December 31, 2008, UTCP shall be paid [***] per piece of Equipment that has successfully completed the Commissioning Test prior to December 31, 2008 and the
remaining balance due in the Mechanical Completion Payment shall be withheld and the reduction of [***] per day shall be applied to the balance until Mechanical Completion is achieved or the balance has been liquidated. 
 The Parties acknowledge and agree that the Initial Start-up and completion of the Commissioning Test of each unit
of Equipment prior to the Guaranteed Mechanical Completion Date requires that (i) each unit of Equipment be fully installed in conformance with UTCP’s Conditions Required For Timely Start-Up/Commissioning Of Purecycle® 225 Powerplants At Raser Therm0 #1 Site and (ii) UTCP be provided with access to the Facility at least forty-five (45) days prior to the Guaranteed Mechanical Completion Date (the
“Access Date”). BUYER shall provide UTCP with all necessary facilities and infrastructure to run the Commissioning Test of each unit of Equipment on or before such Access Date. At a minimum this shall include necessary hot and cold
water flows and the ability to import and export power sufficient to service blocks of Equipment of no fewer than five (5) units at a time. Such facilities shall be provided in a manner to permit UTCP to conduct the Commissioning Test on any
five co-located units within the facility. BUYER shall complete UTCP’s installation requirements and guidelines prior to the Access Date for each unit of Equipment and BUYER shall provide access to UTCP as it completes the installation of each
piece of Equipment to permit UTCP to complete pre-commissioning activities as early as possible. The Guaranteed Mechanical Completion Date shall be extended by one day for each day after October 15, 2008 that the Access Date has not occurred
(the “Delayed Access Date”. 
 In the event that (i) all units of Equipment are not fully installed in conformance with UTCP’s
installation requirements and guidelines and/or (ii) UTCP has not been provided with full access to the Facility for the Initial Start up mobilization prior to the Access Date, and as a result, UTCP is required to perform the Initial Start up
and/or the Commissioning Tests at times or during days when UTCP’S workers are entitled to overtime or premium rates, Buyer agrees to reimburse UTCP for any and all incremental costs associated with the performance of Initial Start up and/or
the Commissioning Tests at overtime or premium rates. 
 PERFORMANCE PENALTIES 
 The full Successful Performance Test Payment amount shall only be due and payable by BUYER to UTCP upon the occurrence of a Successful Performance Test. In the event that Facility performance is below the Contract
Performance Benchmark, or the Adjusted Performance Benchmark, as applicable, the Successful Performance Test Payment shall be reduced in accordance with the performance penalty schedule attached hereto as Exhibit F (the “Performance
Penalties”). The Parties agree that if a Performance Test has not occurred within one-hundred and eighty (180) days following the Guaranteed Mechanical Completion Date, the entire Successful Performance Test Payment shall be forfeited
by UTCP. 
 UTCP LIMITED STEP-IN RIGHT 
 If a
Performance Test is not completed within sixty (60) calendar days of the Guaranteed Mechanical Completion Date, then UTCP may exercise its rights under the Step-In and Standstill Agreement, dated as of the date hereof (the “Step-In and
Standstill Agreement”). 
 UTCP CONSTRUCTION INFORMATION RIGHTS 
 BUYER shall promptly send, or cause to be sent, copies of the monthly progress reports to UTCP that BUYER sends to the Lender; provided, however, that BUYER is entitled to redact confidential, privileged or other
sensitive information therefrom. During the design, engineering, construction, commissioning and performance testing of the Facility, BUYER shall provide a UTCP representative with reasonable access to the Facility and to BUYER’s
representatives, agents and subcontractors to enable UTCP to monitor the progress of the Facility. 
 UTCP’S RECEIPT OF INDEPENDENT
ENGINEER’S REPORT AND ACCEPTABILITY THEREOF 
 The obligations of the Parties under this Agreement shall not be effective until: (i) UTCP
has received a final Lender’s Independent Engineer’s report (the “Engineer’s Report” or the “Report”) from R.W. Beck, Inc. (the “Independent Engineer”); and (ii) the Report shall
be acceptable to UTCP in its reasonable discretion. UTCP shall provide written notice to BUYER acknowledging receipt of the Report and its acceptance to UTCP thereof. For the avoidance of doubt, no payments will be due from BUYER to UTCP until UTCP
has provided such notice to BUYER. 
 In the event the Report is not reasonably acceptable to UTCP, UTCP and BUYER shall work together in good faith for 15
calendar days after UTCP’s receipt of the Report to resolve UTCP’s concerns; such resolution may include, without limitation, a written amendment to this Agreement. 
  

 Page 4 of 9 

 REPURCHASE OPTION 
 In the event that: (i) the Facility has not been placed into commercial operation within six (6) months after the date Mechanical Completion occurs due to events or circumstances not directly caused by or related to the Equipment
or UTCP’s material breach of this Agreement; (ii) BUYER is not diligently working toward placing the Facility into commercial operation; and (iii) BUYER has repaid in full all amounts outstanding under the Credit Agreement, then UTCP
shall have the right, but not the obligation, to repurchase the Equipment for an amount equal to the portion of the Total Contract Price received from BUYER; provided, that in the event UTCP repurchases the Equipment, neither Party shall thereafter
have any liability to the other Party hereunder.

 UTCP warrants that any standard component of the PureCycle®
 System [defined as a standard production PureCycle® System (i.e. the following components and interconnects: the evaporator, the power module and the condenser supplied by UTCP, and
the mechanical and electrical interconnects supplied by UTCP between such components)] that is properly installed, commissioned by UTCP or a UTCP Authorized Service Provider (“ASP”), operated in accordance with the specifications provided
by UTCP and found by UTCP under normal use and service to malfunction during the warranty period solely as a result of material defects in materials or workmanship, will be replaced or repaired at UTCP’s option. 
 This coverage is limited to replacement parts and reasonable transportation and labor, as defined by UTCP, for component removal, repair or replacement, and
reinstallation during the first eighteen (18) months after the date of shipment or twelve (12) months from commissioning, whichever occurs first. 
 This Warranty shall be declared null and void if a commissioning checklist is not received by UTCP within
twenty-five (25) days of commissioning the PureCycle® System. 
 UTCP or an ASP must perform
all preventive maintenance and repairs during the Warranty period. Failure to comply with the recommended preventive maintenance procedures as scheduled in the applicable Operation and Maintenance Manual, and provide UTCP a field service report
(“FSR”) documenting that this preventive maintenance has been performed, and UTCP being in receipt of such FSR within twenty-five (25) days of the maintenance being required as per the schedule, will result in this Warranty being
declared null and void. Buyer must provide and maintain a dedicated analog telephone line or internet service with long distance direct dial and answer capability for UTCP’s remote monitoring service. 
 Malfunctions 
 Malfunctions and defects do not include normal wear and tear, fluctuation in the heat source or consistent lack of heat from the heat source, effects of corrosive and/or erosive environments, fuels or heat sources, condenser or evaporator

 EXHIBIT D-1 
 COMMISSIONING TEST PROCEDURE 
 A four (4) hour Commissioning Test for each unit of Equipment
will be conducted in general accordance with the American Society of Mechanical Engineers (“ASME”) Performance Test Code (“PTC”) 1. A site specific Commissioning Test procedure developed in general accordance with ASME PTC-1 will
be mutually agreed upon by the Parties, such agreement not to be unreasonably withheld. The site specific test procedure will be provided to the Parties prior to the commencement of the Commissioning Test sufficiently in advance to provide a
reasonable period of time to permit a review thereof without causing undue delay to the commencement of the Commissioning Test. The site specific Commissioning Test Procedure shall incorporate and shall be substantially comprised of the
following: 
  

	 	1.	Step One: 

  

	 	a.	Operate each unit of Equipment at the optimal gross electrical output and record the following test parameters for each unit of Equipment (each a “Test Parameter” and
collectively, the “Test Parameters”): 

  

	 	•	 	 Net electrical output (“Net Output”) 

  

	 	•	 	 Hot water resource temperature (“Resource Temp.”) 

  

	 	•	 	 Hot water resource flow rate (“Resource Flow”) 

  

	 	•	 	 Cooling water temperature (“Cooling Temp.”) 

  

	 	•	 	 Cooling water flow rate (“Cooling Flow”) 

  

	 	b.	Recordings for each Test Parameter are to be taken at 10 minute intervals throughout the four (4) hour Commissioning Test period for a total of 25 Test Parameter data points.

  

	 	c.	For each Test Parameter, the average of the 25 recorded Test Parameter data points will be used for purposes of Step Two of Commissioning Test procedure. 

 

	 	2.	Step Two: 

  

	 	a.	Using Figure D1, determine nominal Resource Flow based on the measured Resource Temp. from curve in Figure D11
 (the “Nominal Resource Flow”). 

  

	 	b.	Using Figure D2, calculate Cooling Water Flow Deviation by comparing the measured Cooling Flow to the nominal Cooling Flow of 928 GPM and identify correction factor using
solid curve in Figure D2 (“Cooling Flow Correction Factor”). 

  

	 	c.	Using Figure D2, calculate Cooling Water Temperature Deviation by comparing the measured Cooling Temp. to the nominal Cooling Temp. of 65F and identify correction factor
using dotted curve in Figure D2 (“Cooling Temp. Correction Factor”). 

  

	1	Figure D-1 has been developed based on UTCP’s predictive thermodynamic model. If actual resource conditions are outside the conditions shown in the correction curve in
Figure D-1, the same model will be used to generate updated correction curves, which shall be confirmed by UTCP recreating those curves with the data at the actual operating conditions. At the time the updated correction curves are developed, the
original correction curves will be recreated and plotted with the new curve and compared to the original Figure D-1. 

	 	d.	Calculate corrected Nominal Resource Flow based upon equation in Figure D3 (the “Corrected Resource Flow”). 

 Successful Commissioning Test: 
 The Commissioning Test for all
units of Equipment shall be deemed successful (a “Successful Commissioning Test”) if (i) the sum of the measured Resource Flow of all units of Equipment (the “Aggregate Resource Flow”) is less than or equal to the sum of the
Corrected Resource Flow of all units of Equipment (the “Aggregate Corrected Resource Flow”) and (ii) the average Net Output of all units of Equipment is 250 kW or greater. 
 Conditional Site Requirements for Commissioning Test: 
  

	•	 	 All Test Parameters will be recorded by Buyer, with assistance from Seller, utilizing Buyer supplied monitoring equipment (the “Monitoring Equipment”),
operated in accordance with the Monitoring Equipment manufacturers’ specifications and operating instructions. 

  

	•	 	 The accuracy of all measured Test Parameters shall be determined in accordance with the Monitoring Equipment manufacturers’ specifications.

  

	•	 	 Monitoring Equipment accuracy uncertainties shall be applied to all measured Test Parameters (see example in Figure D4). 

  

	•	 	 Hot water resource pressures shall be sufficient to control dissolved gases, and maintain 10% margin above saturation pressure. Hot water pressure drop across the
evaporator of each unit of equipment (inlet to exit) shall exceed 12psi. 

  

	•	 	 Buyer will manage Facility cooling tower operation to maintain a constant Cooling Temp. and Cooling Flow during the four (4) hour Commissioning Test period. If
a constant Cooling Temp. or Cooling Flow cannot be maintained during the Commissioning Test period, then the Commissioning Test will be postponed until constant Cooling Temp. or Cooling Flow can be maintained.

 Resultant Calculations: 
  

	 	•	 	 Resource Temp. measured at 267F with uncertainty of 2F provides a Nominal Resource Flow at 265F of 240 GPM 

  

	 	•	 	 Cooling Flow measured at 900 GPM with uncertainty of 30 GPM results in a correction factor at 870 GPM of 1.03 

  

	 	•	 	 Cooling Temp. measured at 66F with uncertainty of 2F results in a correction factor at 68F of 1.06 

  

	 	•	 	 Resource flow measured at 260 GPM – 13 GPM (uncertainty) = 247 GPM 

  

	 	•	 	 Corrected Resource Flow: 240 GPM * 1.03 * 1.06 = 262 GPM
