 This Mining
Lease and Agreement is subject to, and Lessee hereby agrees to and accepts, the following covenants, terms, and conditions: 
  

	1.	LEASED SUBSTANCES. 

  

	 	1.1	Geothermal Steam, as Classified and defined in Utah Administrative Code R850-27-100 (collectively “leased substances”). This mineral lease grants Lessee the
right, subject to the terms and conditions set forth herein, to extract the leased substances. In the event that minerals or materials other than the leased substances are discovered during lease operations, Lessee shall promptly notify the Lessor
and shall not further disturb or remove the other minerals or materials without Lessor’s written permission. Upon notifying Lessor of such discovery the Lessee shall have preference in making application to the Lessor for a lease or permit
covering the unleased minerals or materials that are discovered. 

  

	 	1.2	Ore From Adjacent Lands; Transport Fee, Process Fee. Lessee may use mine workings, portals and ore processing facilities located on the Subject Property to transport or
process ore extracted from non-state lands adjacent to or nearby the Subject Property. As a condition of Lessor’s consent to such use of the Subject Property, Lessee shall pay Lessor a fee per ton of ore attributable to non-state lands that is
removed from portals located on the Subject Property and transported offsite or processed on site. Lessee shall also pay Lessor a fee per ton of any other ore that is mined from non-state lands and is transported to the Subject Property for
processing at a facility located upon the Subject Property. Said transport or process fee per ton shall be paid at One-half the leased substances royalty rate as contained in Paragraph 6 of this lease. Lessee shall maintain separate stockpiles of
ore removed from the Subject Property and ores attributable to non-state lands, and shall not commingle such ores. For purposes of this paragraph, weight of ores shall be the “dry weight,” determined by taking moisture content
measurements, and deducting the average moisture from the ore weight, measure at the point of receipt at the mill or other processing facility. For all ore subject to the transport or process fee that is transported for milling or processing during
a particular month, Lessee shall pay transport or process fees to Lessor on or before the end of the next succeeding month. Transport or process fees shall be accounted for separately on the monthly royalty settlement sheet required to be submitted
by Lessee pursuant to paragraph 6.4, Royalty Payment. 

  

	 	1.3	No Warranty of Title. Lessor claims title to the mineral estate covered by this Lease. Lessor does not warrant title nor represent that no one will dispute the title asserted
by Lessor. It is expressly agreed that Lessor shall not be liable to Lessee for any alleged deficiency in title to the mineral estate, nor shall Lessee become entitled to any refund for any rentals, bonuses, or royalties paid under this Lease in the
event of title failure. 

  

	2.	RESERVATIONS TO LESSOR. Subject to the exclusive rights and privileges granted to Lessee under this Lease, and further provided that Lessor shall refrain from taking actions
with respect to the Leased Premises that may unreasonably interfere with Lessee’s operations, Lessor hereby excepts and reserves from the operation of this Lease the following rights and privileges (to the extent that Lessor has the right to
grant such rights and privileges): 

  

	 	2.1	Rights-of-Way and Easements. Lessor reserves the right, following consultation with the Lessee, to establish rights-of-way and easements upon, through or over the Leased
Premises, under terms and conditions that will not unreasonably interfere with operations under this Lease, for roads, pipelines, electric transmission lines, transportation and utility corridors, mineral access, and any other purpose deemed
reasonably necessary by Lessor.

	 	2.2	Other Mineral Leases. Lessor reserves the right to enter into mineral leases and agreements with third parties covering minerals other than the leased substances, under terms
and conditions that will not unreasonably interfere with operations under this Lease in accordance with Lessor’s regulations, if any, governing multiple mineral development. 

  

	 	2.3	Use and Disposal of Surface. To the extent that Lessor owns the surface estate of the Leased Premises and subject to the rights granted to the Lessee pursuant to this Lease,
Lessor reserves the right to use, lease, sell, or otherwise dispose of the surface estate or any part thereof, provided that any such actions will not unreasonably interfere with operations under this Lease. Lessor shall notify Lessee of any such
sale, lease, or other disposition of the surface estate. 

  

	 	2.4	Rights Not Expressly Granted. Lessor further reserves all rights and privileges of every kind and nature, except as specifically granted in this Lease, provided that any
actions under such reservations will not unreasonably interfere with operations under this Lease. 

  

	3.	TERM OF LEASE; MINIMUM ROYALTIES; READJUSTMENT. 

  

	 	3.1	Primary Term. This Lease is granted for a “primary term” of ten (10) years from the date hereinabove first written. 

  

	 	3.2	Extension Beyond Primary Term By Production. Subject to Lessee’s compliance with the other provisions of this Lease, this Lease shall remain in effect beyond the primary
term so long as leased substances are being produced in paying quantities, as defined herein, from the Leased Premises, or from lands constituting a mining unit as approved by Lessor in its reasonable discretion. For purposes of this lease,
production of leased substances in paying quantities shall mean the mining and sale of the leased substances during the lease-year in an amount sufficient to cover all operating expenses accruing to the lessee pursuant to the leasehold for that
lease year, including the payment of all taxes and the payment of rentals and royalties accruing to the Lessor. 

  

	 	3.3	Extension Beyond Primary Term By Diligent Development, Financial Investment and Minimum Royalty. In the absence of actual production in paying quantities as set forth in
paragraph 3.2, Extension Beyond Primary Term, this Lease shall remain in effect beyond the primary term only if the Lessee is engaged in diligent operations, exploration or development activity, as well as making a substantial financial investment,
which in Lessor’s sole discretion is calculated to advance development or production of leased substances from the Leased Premises or lands constituting a mining unit as approved by the Director which includes the Leased Premises, and Lessee
pays the annual minimum royalty set forth in Paragraph 3.4, Minimum Royalty, in advance, on or before the anniversary date of the date first written hereinabove. 

  

	 	3.4	Minimum Royalty. Commencing with the n/a year of this lease Lessee shall pay Lessor an annual minimum royalty, in advance, on or before the Effective Date and each
anniversary thereof. The advance annual minimum royalty shall be in the amount of $ n/a. Lessee may credit each lease-year’s minimum royalty payment against actual production royalties accruing during that lease year, but such credit shall not
carry over beyond the lease year in which the advance royalty was paid. Minimum royalties may not be credited against the annual rentals or bonus bids.

	 	3.5	Expiration; Cessation of Production. This Lease may not be extended pursuant to paragraph 3.3, Diligent Operations, beyond the end of the twentieth year after the Effective
Date except by the actual production of leased substances in commercial quantities from the Leased Premises or from lands constituting an approved mining unit which includes the Leased Premises, or except by suspension of the Lease pursuant to
Article 17.3, unless otherwise specifically approved in writing by the Director of the Trust Lands Administration in the interest of the trust beneficiaries. After expiration of the primary term, this Lease will expire of its own terms, without the
necessity of any notice or action by Lessor, if: (a) Lessee fails to produce leased substances in accordance with Article 3.2; (b) Lessee ceases to engage in exploration, development, or operations or fails to pay annual advance minimum
royalties in accordance with Article 3.4; or, (c) the Director fails to make a written determination that it is in the interest of the trust beneficiaries to extend this lease. 

  

	 	3.6	Readjustment. At the end of the primary term and at the end of each period of ten (10) years thereafter (“Readjustment Period”), Lessor may exercise its option
to readjust the terms and conditions of this Lease (including, without limitation: rental rates, minimum royalties, royalty rates, valuation methods, and provisions concerning reclamation). Notice of intent to exercise the right to readjust is
timely given by Lessor if mailed prior to the end of the Readjustment Period to the last address set forth for Lessee in Lessor’s files. Lessor shall have up to one year after exercising its option to readjust to review and communicate in
writing the final readjusted terms of the lease. If within thirty (30) days after submission of the readjusted lease terms to the Lessee, the Lessee determines that any or all of the proposed readjusted terms and conditions are unreasonable,
then Lessee shall so notify Lessor in writing and the parties, acting reasonably, shall attempt to resolve the objectionable term or condition. If the parties are unable, acting reasonably, to resolve the matter and agree upon the readjusted terms
and conditions as submitted by Lessor at the end of the Readjustment Period, Lessee shall forfeit any right to the continued extension of this lease, and the lease shall automatically terminate, provided that nothing herein shall be deemed to
preclude Lessee from appealing any readjustment by Lessor pursuant to applicable law. 

  

	4.	BONUS BID. Lessee agrees to pay Lessor an initial bonus bid in the sum of n/a dollars as partial consideration for Lessor’s issuance of this Lease, payable in cash prior
to execution of this lease. The initial bonus bid may not be credited against annual rentals, annual minimum royalties or production royalties accruing pursuant to this lease. 

  

	5.	RENTALS/MINIMUM RENTALS. Lessee agrees to pay Lessor an annual rental of $1.00 for each acre and fractional part thereof within the Leased Premises; provided however, the
minimum annual rental required by this lease shall be $500.00 irrespective of acreage. Lessee shall promptly pay annual rentals each year in advance on or before the anniversary date of the Effective Date. The rental payment for a mineral lease year
may be credited against production royalties only as they accrue for that lease year. The Lessee may not credit rentals paid for one lease year against production royalties accruing to another lease year. Rental payments may not be credited against
minimum royalties or bonus bids accruing to any lease year.

	6.	ROYALTIES. 

  

	 	6.1	Production Royalties. Lessee shall pay Lessor a production royalty on the basis of 10% of the Gross Value, f.o.b. the mine, of the leased substances sold under an arm’s
length transaction, bona fide contract of sale or $ n/a per short ton, whichever amount is greater. For purposes of this lease the Gross Value of the leased substances shall mean the actual compensation received by the Lessee, or any affiliated
entity, on the basis of U.S. Dollars, including all payments, bonuses and allowances, received plus the value of all services, payments in kind and all other compensation whether monetary or non-monetary, received by the Lessee from the buyer or
from other parties for the sale or disposal of the leased substances. 

  

	 	6.2	Non-Arms Length Transactions. In the event that Lessee uses, sells or otherwise disposes of leased substances without a non-arm’s-length contract or bill of sale, Lessee
shall promptly notify Lessor of such use, sale or disposal. The Director may then determine and assign the Gross Value to the leased substances for royalty purposes after taking into account spot market prices, the value of similar or like leased
substances reported by other trust lands lessees, the value of like mineral commodities as reported by the United States Geological Survey, and other pertinent economic data regarding the fair market value of the leased substances, f.o.b. the mine.


  

	 	6.3	No Deductions. It is expressly understood and agreed that none of Lessee’s mining, production or processing costs, including but not limited to costs for materials,
labor, overhead, distribution, transportation f.o.b. mine, loading, crushing, processing, or general and administrative activities, may be deducted in computing Lessor’s royalty. All such costs shall be entirely borne by Lessee and are
anticipated by the rate of royalty set forth in this Lease. 

  

	 	6.4	Royalty Payment. For all leased substances that are sold or transported from the leased lands during a particular month, Lessee shall pay royalties to Lessor on or before the
end of the next succeeding month. Royalty payments shall be accompanied by a verified statement, in a form approved by Lessor, stating the amount of leased substances sold or transported, the gross proceeds accruing to Lessee, and any other
information reasonably required by Lessor to verify production and disposition of the leased substances or leased substances products. Delinquent royalties may be subject to late fees and penalties in accordance with Lessor’s Rules.


  

	 	6.5	Suspension, Waiver or Reduction of Rents or Royalties. Lessor, to the extent not prohibited by applicable law, is authorized to waive, suspend, or reduce the rental or
minimum royalty, or reduce the royalty applicable with respect to the entire Lease, whenever in Lessor’s sole judgment it is necessary to do so in order to promote development, or whenever in the Lessor’s sole judgment the Lease cannot be
successfully operated under the terms provided herein and continued operations are in the trust land beneficiaries best interest. 

  

	7.	RECORDKEEPING; INSPECTION; AUDITS. 

  

	 	7.1	 Registered Agent; Records. Lessee shall maintain a registered agent within the State of Utah to whom any and all notices may be sent by Lessor and upon whom
process may be served. Lessee shall also maintain an office within the State of Utah containing originals or copies of all maps, engineering data, permitting materials, books, records or contracts (whether such documents are in paper or electronic
form) generated by Lessee that pertain in any way to leased substances production, output and valuation; mine operations; assays; processing returns; leased substances sales and dispositions; and calculation

of royalties from the Leased Premises. Lessee shall maintain such documents for at least seven years after the date of the leased substances production to
which the documents pertain. 


  

	 	7.2	Inspection. Lessor’s employees and authorized agents at Lessor’s sole risk and expense shall have the right to enter the Leased Premises to check scales as to their
accuracy, and to go on any part of the Leased Premises to examine, inspect, survey and take measurements for the purposes of verifying production amounts and proper lease operations. Upon reasonable notice to Lessee, Lessor’s employees and
authorized agents shall further have the right to audit, examine and copy (at Lessor’s expense) all documents described in paragraph 7.1, Registered Agent; Records, whether such documents are located at the mine site or elsewhere. Lessee shall
furnish all conveniences necessary for said inspection, survey, or examination; provided, however, that such inspections shall be conducted in a manner that is in conformance with all applicable mine safety regulations and does not unreasonably
interfere with Lessee’s operations. 

  

	 	7.3	Geologic Information. In the event Lessee conducts core-drilling operations or other geologic evaluation of the Leased Premises, Lessor may inspect core samples, evaluations
thereof, and proprietary geologic information concerning the Leased Premises. Upon request by Lessor, Lessee shall timely provide Lessor with a true and correct copy of all such evaluations, geological reports, drilling logs, assays and interpretive
maps of the leased substances within the leased lands. 

  

	 	7.4	Confidentiality. Any and all documents and geologic data obtained by Lessor through the exercise of its rights as set forth in paragraphs 7.2, Inspection., and 7.3, Geologic
Information., may be declared confidential information by Lessee, in which event Lessor and its authorized agents shall maintain such documents and geologic data as protected records under the Utah Governmental Records Access Management Act or other
applicable privacy statute, and shall not disclose the same to any third party without the written consent of Lessee, or as required under the order of a court of competent jurisdiction requiring such disclosure, provided that Lessor’s
obligations of confidentiality to Lessee shall cease upon termination of this Lease. 

  

	8.	USE OF SURFACE ESTATE. 

  

	 	8.1	Lessor-Owned Surface. If Lessor owns the surface estate of all or some portion of the Leased Premises, at the time of the execution of this Lease, by issuance of this Lease
the Lessee has been granted the right to make use of such lands to the extent reasonably necessary and expedient for the economic operation of the leasehold. Lessee’s right to surface use of Lessor-owned surface estate shall include the right
to subside the surface. Such surface uses shall be exercised subject to the rights reserved to Lessor as provided in paragraph 2, RESERVATIONS TO LESSOR, and without unreasonable interference with the rights of any prior or subsequent lessee of
Lessor. 

  

	 	8.2	Split-Estate Lands. If Lessor does not own the surface estate of any portion of the Leased Premises, Lessee’s access to and use of the surface of such lands shall be
determined by applicable law governing mineral development on split-estate lands, including without limitation applicable statutes governing access by mineral owners to split estate lands, and reclamation and bonding requirements. Lessee shall
indemnify, defend and hold Lessor harmless for all claims, causes of action, damages, costs and expenses (including attorney’s fees and costs) arising out of or related to damage caused by Lessee’s operations to surface lands or
improvements owned by third parties.

	10.	BONDING. 

  

	 	10.1	Lease Bond May Be Required. At the time this Lease is executed, Lessor may require Lessee to execute and file with the Lessor a good and sufficient bond or other financial
guarantee acceptable to Lessor in order to: (a) guarantee Lessee’s performance of all covenants and obligations under this Lease, including Lessee’s obligation to pay royalties; and (b) ensure compensation for damage, if any, to
the surface estate and any surface improvements. 

  

	 	10.2	Reclamation Bonding. The bond required by and filed with the Utah Division of Oil, Gas and Mining (“UDOGM”) in connection with the issuance of a mine permit which
includes the Leased Premises may be accepted by the Director to satisfy Lessor’s bonding requirements with respect to Lessee’s reclamation obligations under this Lease; provided, however, upon notice to Lessee, the Lessor may, in its
reasonable discretion, determine that the bond filed with UDOGM is insufficient to protect Lessor’s interests. In such an event the Director shall enter written findings as to the basis for calculation of the perceived insufficiency and enter
an order establishing the amount of additional bonding required. Lessee shall file any required additional bond with Lessor within thirty (30) days after demand by Lessor. Lessor may increase or decrease the amount of any additional bond from
time to time in accordance with the same procedure. 

  

	11.	WATER RIGHTS. 

  

	 	11.1	Water Rights in Name of Lessor. If Lessee files to appropriate water for use in association with this lease or operations upon the Leased Premises, the filing for such water
right shall be made by Lessee in the name of Lessor at no cost to Lessor, and such water right shall become an appurtenance to the Leased Premises, subject to Lessee’s right to use such water right at no cost during the term of this Lease.


  

	 	11.2	 Option to Purchase. If Lessee purchases or acquires an existing water right for use in association with this lease or operations upon the Leased Premises,
Lessor shall have the option to acquire that portion of such water right as was used on the Leased Premises upon expiration or termination of this Lease. The option price for such water right shall be the fair market value of the water right as of
the date of expiration or termination of this Lease. Upon expiration or termination of this Lease, Lessee shall notify Lessor in writing of all water rights purchased or acquired by Lessee for leased substances mining operations on the Leased
Premises and its estimate of the fair market value of such water right. Lessor shall then have forty-five (45) days to exercise its option to acquire the water by payment to Lessee of the estimated fair market value. If Lessor disagrees with
Lessee’s estimate of fair market value, Lessor shall notify Lessee of its disagreement within the 45 day option exercise period. The fair market value of the water right shall then be appraised by a single appraiser

mutually acceptable to both parties, which appraisal shall be final and not subject to review or appeal. If the parties cannot agree upon the choice of an
appraiser, the fair market value of the water right shall be determined by a court of competent jurisdiction. Conveyance of any water right pursuant to this paragraph shall be by quit claim deed. 


  

	12.	ASSIGNMENT OR SUBLEASE; OVERRIDING ROYALTIES. 

  

	 	12.1	Consent Required. Lessee shall not assign or sublease this Lease in whole or in part, or otherwise assign or convey any rights or privileges granted by this Lease, including,
without limitation, creation of overriding royalties or production payments, without the prior written consent of Lessor, which shall not be unreasonably withheld. Lessee agrees that Lessor, in determining whether to consent to any proposed
assignment, may reasonably consider the proposed assignee’s financial capacity, ability to market and process leased substances, and may refuse to consent to such assignment if, in the Lessor’s reasonable opinion, the proposed assignee
lacks the necessary financial or technical capacity to mine, market and/or process leased substances in a manner comparable to Lessee. Any assignment, sublease or other conveyance made without prior written consent of Lessor shall have no legal
effect unless and until approved in writing by Lessor. Exercise of any right with respect to the Leased Premises in violation of this provision shall constitute a default under this Lease. 

  

	 	12.2	Binding Effect. All of the terms and provisions of this Lease shall be binding upon and shall inure to the benefit of their respective successors, assigns, and sublessees.


  

	 	12.3	Limitation on Overriding Royalties. Lessor reserves the right to disapprove the creation of an overriding royalty or production payment that would, in Lessor’s
reasonable discretion, constitute an unreasonable economic burden upon operation of the Lease. In exercising its discretion to disapprove the creation of an overriding royalty, Lessor shall consult with Lessee and any third parties involved and
shall prepare findings to evidence the basis of its decision. Any transfer in interest which would create a cumulative overriding royalty burden in excess of 20% shall not be approved. 

  

	13.	OPERATIONS. 

  

	 	13.1	Permitting. Before Lessee commences exploration, drilling, or mining operations on the Leased Premises, it shall have obtained such permits and posted such bonds as may be
required under applicable provisions of the Utah Mined Land Reclamation Act and associated regulations. Lessee shall maintain any required permits in place for the duration of mining operations and reclamation. Upon request, Lessee shall provide
Lessor with a copy of all regulatory filings relating to permitting matters. 

  

	 	13.2	Plan of Operations. Prior to the commencement of any exploration, drilling, or mining operations on the Leased Premises, Lessee shall obtain Lessor’s approval of a plan
of operations for the Leased Premises. Lessor may modify the proposed plan of operations as is needed to insure that there is no waste of economically recoverable mineral reserves contained on the Leased Premises. In this context “waste”
shall mean the inefficient utilization of, or the excessive or improper loss of an otherwise economically recoverable mineral resource. Lessor shall notify Lessee in writing of its approval or modifications of the plan of operations. The plan of
operations submitted by Lessee shall be deemed approved by Lessor if Lessor has not otherwise notified Lessee within sixty (60) days of filing.

	 	13.3	Plan of Operations - Modification. In the event that material changes are required to the plan of operations during the course of mining, Lessee shall submit a modification
of the plan of operations to the Lessor. Routine adjustments to the plan of operations based upon geologic circumstances encountered during day-to-day mining operations do not require the submission of a modification. If the proposed changes require
emergency action by Lessor, then the Lessee shall so notify the Lessor at the time of submission of the modification and the parties shall use their best efforts to meet the Lessee’s time schedule regarding implementation of the changes.
Non-emergency modifications will be reviewed promptly by Lessor to insure that there is no waste of economically recoverable mineral reserves pursuant to the plan of operations, as modified, and Lessor shall notify lessee in writing of its approval
or modification of the proposed modification. Modifications shall be deemed approved by Lessor if Lessor has not otherwise notified Lessee within thirty (30) days of filing. 

  

	 	13.4	Mine Maps. Lessee shall maintain at the mine office clear, accurate, and detailed maps of all actual and planned operations. Such maps shall be certified by an engineer or
geologist who is professionally licensed by the State of Utah or by a state having a reciprocal licensing agreement with the State of Utah. Lessee shall provide copies of such maps to Lessor upon request. 

  

	 	13.5	Good Mining Practices. Lessee shall conduct exploration and mining operations on the Leased Premises in accordance with standard industry operating practices, and shall avoid
waste of economically recoverable leased substances. Lessee shall comply with all regulations and directives of the Mine Safety and Health Administration or successor agencies for the health and safety of employees and workers. Leased substances
shall be mined from this Lease by underground methods only. 

  

	 	13.6	Mining Units. Lessor may approve the inclusion of the Leased Premises in a mining unit with federal, private or other non-state lands upon terms and conditions that it deems
necessary to protect the interests of the Lessor, including without limitation segregation of production, accounting for commingled leased substances production, and minimum production requirements or minimum royalties for the Leased Premises.


  

	14.	EQUIPMENT; RESTORATION. 

  

	 	14.1	Equipment. Upon termination of this Lease, Lessee shall remove, and shall have the right to remove, all improvements, equipment, stockpiles, and dumps from the Leased
Premises within six (6) months; provided, however, that Lessor may, at Lessor’s sole risk and expense, and subject to Lessee’s compliance with requirements imposed by UDOGM and MSHA, require Lessee to retain in place underground
timbering supports, shaft linings, rails, and other installations reasonably necessary for future mining of the Leased Premises. All improvements and equipment remaining on the Leased Premises after six (6) months may be deemed forfeited to
Lessor upon written notice of such forfeiture to Lessee. Lessee may abandon underground improvements, equipment of any type, stockpiles and dumps in place if such abandonment is in compliance with applicable law, and further provided that Lessee
provides Lessor with financial or other assurances sufficient in Lessor’s reasonable discretion to protect Lessor from future environmental liability with respect to such abandonment or any associated hazardous waste spills or releases. Lessee
shall identify and locate on the mine map the location of all equipment abandoned on the Lease Premises.

	 	14.2	Restoration and Reclamation. Upon termination of this Lease, Lessee shall reclaim the Leased Premises in accordance with the requirements of applicable law, including mine
permits and reclamation plans on file with UDOGM. Lessee shall further abate any hazardous condition on or associated with the Leased Premises. Lessee and representatives of all governmental agencies having jurisdiction shall have the right to
re-enter the Leased Premises for reclamation purposes for a reasonable period after termination of the Lease. 

  

	15.	MULTIPLE MINERAL DEVELOPMENT. 

 The Utah School and
Institutional Trust Lands Administration may designate any lands under its authority as a Multiple Mineral Development Area (MMD). In designated MMDs the Lessor may require in addition to the terms and conditions of this lease such stipulations or
restrictions as may be necessary in the determination of the Director to integrate and coordinate the operations of lessees having an interest in the lands in order to conserve natural resource and optimize revenues to the trust-land beneficiaries.

  

	16.	DEFAULT 

  

	 	16.1	Notice of Default; Termination. Upon Lessee’s violation of or failure to comply with any of the terms, conditions or covenants set forth in this Lease, Lessor shall
notify Lessee of such default by registered or certified mail, return receipt requested, at the last address for Lessee set forth in Lessor’s files. Lessee shall then have thirty (30) days, or such longer period as may be granted in
writing by Lessor, to either cure the default or request a hearing pursuant to the Lessor’s administrative adjudication rules. In the event Lessee fails to cure the default or request a hearing within the specified time period, Lessor may
cancel this Lease without further notice to or appeal by Lessee. 

  

	 	16.2	Effect of Termination. The termination of this Lease for any reason, whether through expiration, cancellation or relinquishment, shall not limit the rights of the Lessor to
recover any royalties and/or damages for which Lessee may be liable, to recover on any bond on file, or to seek injunctive relief to enjoin continuing violations of the Lease terms. No remedy or election under this Lease shall be deemed exclusive,
but shall, wherever possible, be cumulative with all other remedies available under this Lease, at law, or in equity. Lessee shall surrender the Leased Premises upon termination; however, the obligations of Lessee with respect to reclamation,
indemnification and other continuing covenants imposed by this Lease shall survive the termination. All fees, rentals and monies of any type previously paid by the Lessee to the Lessor are forfeited to the trust. 

  

	17.	MISCELLANEOUS PROVISIONS. 

  

	 	17.1	Indemnity. Except as limited by paragraph 7.2, Inspection, Lessee shall indemnify and hold Lessor harmless for, from and against each and every claim, demand, liability,
loss, cost, damage and expense, including, without limitation, attorneys’ fees and court costs, arising in any way out of Lessee’s occupation and use of the Leased Premises, including without limitation claims for death, personal injury,
property damage, and unpaid wages and benefits. Lessee further agrees to indemnify and hold Lessor harmless for, from and against all claims, demands, liabilities, damages and penalties arising out of any failure of Lessee to comply with any of
Lessee’s obligations under this Lease, including without limitation reasonable attorneys’ fees and court costs. Lessee may be required to obtain insurance in a type and in an amount acceptable to Lessor, naming the Trust Lands
Administration, its employees, its Board of trustees and the State of Utah as co-insured parties under the policy.

	 	17.2	Interest. Interest shall accrue and be payable on all obligations arising under this Lease at such current rate as may from time to time be enacted by the Director and
recorded in the Director’s Minutes of the School and Institutional Trust Lands Administration. Interest shall accrue and be payable, without necessity of demand, from the date each such obligation shall arise. 

  

	 	17.3	Suspension. In the event that Lessor in its reasonable discretion determines that suspension is necessary in the interests of conservation of the leased substances; that
prevailing market conditions for the leased substances render continued operation of the subject property uneconomic, or if Lessee has been prevented from performing any of its obligations or responsibilities under this Lease or from conducting
mining operations by labor strikes, fires, floods, explosions, riots, acts of terrorism, any unusual mining casualties or conditions, Acts of God, government restrictions or orders, severe weather conditions, or other extraordinary events beyond its
control, then the time for performance of this Lease by Lessee shall be suspended during the continuance of such conditions or acts which prevent performance, excepting any payments due and owing to Lessor. 

  

	 	17.4	Consent to Suit; Jurisdiction. This Lease shall be governed by the laws of the State of Utah. Lessor and Lessee agree that all disputes arising out of this Lease shall be
litigated only in the Third Judicial District Court for Salt Lake County, Utah, and Lessee consents to the jurisdiction of such court. Lessee shall not bring any action against Lessor without exhaustion of available administrative remedies and
compliance with applicable requirements of the Utah Governmental Immunity Act. 

  

	 	17.5	No Waiver. No waiver of the breach of any provision of this Lease shall be construed as a waiver of any preceding or succeeding breach of the same or any other provision of
this Lease, nor shall the acceptance of rentals or royalties by Lessor during any period of time in which Lessee is in default be deemed to be a waiver of such default. 

  

	 	17.6	Severability. The invalidity of any provision of this Lease, as determined by a court of competent jurisdiction, shall in no way affect the validity of any other provision
hereof. 

  

	 	17.7	Entire Lease. This Lease, together with any attached stipulations, sets forth the entire agreement between Lessor and Lessee with respect to the subject matter of this Lease.
No subsequent alteration or amendment to this Lease shall be binding upon Lessor and Lessee unless in writing and signed by each of them.
