		Re:	Extension

Dear
Ms. Elda Beethe and Ms. Beverly Beethe:

 

Reference
is made to the Option to Purchase dated April 30, 2010, together with each attachment thereto (i.e. Exhibit “A”, Exhibit
“B”, the Addendum (“the Addendum”) and the Confidentiality Agreement, each an “Attachment”
and, collectively, the “Attachments”; and the Option to Purchase together with all of the Attachments, the “Option”)
that was executed between Elda and the Company. The Option is attached to this letter (“Extension Agreement”)
as Exhibit “A”. Pursuant to that certain Warranty Deed, dated as of April 22, 2015, and recorded with the Johnson County
Register of Deeds on April 27, 2015, in Book 58, on Page 603, Elda transferred to Beverly an undivided one-half (1/2) interest
in and to the Section 33 Portion (as defined in paragraph 2 of this Option) of the Real Property. As set forth below, Beverly agrees
that her ownership interest in the Real Property is subject to, and that she is bound by the terms and conditions of, the Option,
and therefore, has also agreed, together with Elda to execute this Extension Agreement.

 

All
capitalized terms not otherwise defined in this Extension Agreement shall have the meanings given to such terms in the Option.
Among its terms, the Option provides that the Company must exercise its rights to purchase the Real Property during the Option
Period. Under the Option, the Option Period expires as of 11:59 p.m. on April 29, 2015. Subject to the other provisions of this
Extension Agreement, including the Company’s payment of the Extension Payments (as defined in paragraph 1 of this Extension
Agreement), the Company and each of Elda and Beverly (individually and collectively, “you”) wish to extend
the Option and the Option Period.

 

Please
execute this Extension Agreement in the space provided below, understanding that in doing so each of you and the Company are agreeing
to be bound by the following terms and provisions:

 

1.          Extension
of Option and Option Period. The Option, including without limitation the Company’s right to purchase the
Real Property pursuant to the Option, and the Option Period are hereby extended until 11:59 p.m. (Central) on April 29, 2020 (the
“Extended Option Period”) in consideration of the following payments (“Extension Payment(s)”):

 

(a)          A
single payment by the Company to you in the aggregate amount of [**] within ten (10) days after the Effective Date (as defined

of the Extension Payments made by the Company to you shall be deducted from the Purchase Price (as defined in the Option); provided,
however, that if the Option is exercised or terminated by the Company prior to the due date for any Extension Payment identified
in (b) of this paragraph 1, the Company shall not be obligated to pay any Extension Payment becoming due after the date of any
termination of the Option by the Company or date of the closing (“Closing”) of the purchase and sale of the Real

provided that all conditions to Closing set forth in the Option and this Extension Agreement then have been satisfied or waived

avoid any doubt, the parties agree that any reference in the Option to the expiration of any of: (i) the Option, (ii) the Option
Period, (iii) the Option Term, (iv) the term of the Option, or (v) any similar reference, shall mean and refer to the expiration

to the terms and provisions in the Option, and that she agrees to be bound by the terms and provisions of the Option (as an “Owner”
of the Real Property) and the terms and provisions of this Extension Agreement.

 

2.           Real
Property: Property. The definition of “Real Property” set forth in the introductory paragraph in the
Option to Purchase shall be replaced with the definition of “Real Property” set forth in this paragraph 2, and on
and after the Effective Date, any reference in the Option or this Extension Agreement to “Real Property” or
“Property” (as the case may be) shall mean and refer to all of your individual and collective rights, privileges,
title and interests of any nature whatsoever in and to the real estate (as defined in Neb. Rev. Stat. § 76-201 (Reissue 2013)),
except for the Life Estate and the Net Smelter Return Royalty that may be reserved by you upon Closing of the Transaction as provided

(g)          For
avoidance of any doubt, each of you and the Company agree that in the event any provision contained in the Option, including the
Addendum, or this Extension Agreement is in conflict with the provisions of this paragraph 4(g), the following provisions of this
paragraph 4(g) shall govern, control and prevail:

 

(i)          If
the Company exercises its right to purchase the Real Property pursuant to the Option and the Transaction is thereafter to be Closed,
each of you agree that at Closing you will convey to the Company by general warranty deed, good and marketable fee title in and
to all of your respective individual and collective rights, privileges, title and interest in and to the Real Property, free and
clear of all covenants, easements (other than easements of record as of the date of the Option), restrictions (other than restrictions
of record as of the date of the Option), liens (other than the lien of any ad valorem real estate taxes or installments of special

such right of use and occupancy, will automatically terminate without further action by the Company effective as of the date that
neither of you is occupying, as your permanent personal residence, the residence constructed on the Life Estate Surface Area. Each
of you agree also that use and occupancy of the Life Estate Surface Area by you at all times is subject to, and must be in compliance
with, the other applicable provisions of this Extension Agreement; and

 

(ii)         If
the Company exercises its right to purchase the Real Property pursuant to the Option and the Transaction is thereafter to be Closed,
then in the warranty deed conveying the Real Property to the Company, you hereby reserve unto yourself for your benefit and for
the benefit of your respective heirs, executors, personal representatives, successors, assigns and legal representatives the right
to be paid the Net Smelter Return Royalty pursuant to Section 11 of the Addendum, as amended in paragraph 4(h) below.

 

(h)          Section
11 of the Addendum shall be deleted in its entirety and replaced with the following:

 

“If
Optionee exercises its right to purchase the Real Property pursuant to the Option and also elects to close on the purchase of the
Real Property, then in the deed conveying the Real Property to Optionee, there shall be reserved in favor of the Owners, their
heirs, executors, successors, assigns and legal representatives, a Net Smelter Return Royalty as hereinafter provided. Optionee
agrees that it will accept at Closing a deed from each Owner containing a reservation of Net Smelter Return Royalty, and Optionee
will thereafter record such deed(s) and execute and record any additional documentation or instruments as may be necessary or reasonably
appropriate for such purposes. As used herein, “Net Smelter Return Royalty” shall mean a real property interest in a
portion of the production of minerals from the Real Property, entitling Owners to receive a perpetual royalty in the amount of
2% of the Net Proceeds received by Optionee from the sale or other disposition of Mineral Substances (as hereinafter defined) produced
from minerals extracted from the Real Property, which may include but are not limited to ferroniobium, other niobium compounds
if any, titanium dioxide, other titanium compounds if any, scandium trioxide, other scandium compounds if any, and all other Mineral
Substances that are produced from minerals extracted from the Real Property and sold by Optionee, whether as products, co-products,
or by-products determined as set forth below.

(a)
“Net Proceeds” shall mean the gross proceeds received by Optionee, its successors or assigns, from a buyer of Mineral
Substances for the sale of such Mineral Substances produced from minerals extracted from the Real Property, minus all operating
costs of producing and selling such Mineral Substances, including but not limited to, the operating costs of mining, milling, flotation,
solvent extraction, precipitation, furnace smelting, electrolysis, electrowinning, or other processes required to put Mineral Substances
into saleable condition at the Elk Creek Plant, Owner’s proportionate share of the costs of packaging, shipping and insurance in
transit if such costs are part of the price for Mineral Substances delivered to a third party independent buyer, Owner’s proportionate
share of gross production, severance and similar taxes inuring on or measured by production or sales, and Owner’s proportionate
share of penalties, assaying and sampling charges if such charges are required by a third party independent buyer, but not including
capital costs.

 

(b) For purposes of calculating Net Proceeds, gross proceeds shall be determined by multiplying the volume, or weight, as
appropriate, of Mineral Substances sold, by

 

(i)
the actual unit price received for sale of Mineral Substances at the Elk Creek Plant to an unaffiliated third party purchaser during
the applicable royalty period, or

 

(ii)
if a disposition of Mineral Substances is made by Optionee, via internal transfer or sale to a party affiliated with Optionee,
during the applicable royalty period without an actual sale to an unaffiliated third party purchaser, then the average price reported
by metal-pages.com during the applicable royalty period, or

 

(iii)
if a disposition of Mineral Substances is made by Optionee, via internal transfer or sale to a party affiliated with Optionee,
during the applicable royalty period without an actual sale to an unaffiliated third party purchaser, and the prices cannot be
determined by using metal-pages.com, then the price for the Mineral Substances shall be as mutually agreed between the parties.
If the parties are unable to reach agreement, they will appoint a mutually agreeable third party appraiser qualified to accurately
determine the fair market value of the Mineral Substances.

 

(c)
Payment, accounting: Payment of the Net Smelter Return Royalty shall be due and payable within (60) days of the quarter
ending following the first sale of any Mineral Substances produced from minerals extracted from the Real Property, and
quarterly thereafter. All payments or credits for payment of the Net Smelter Return Royalty shall be accompanied by a
detailed statement explaining the manner in which the payment was calculated. Such payments and statements shall be delivered
no later than sixty (60) days after the end of the calendar quarter in which Mineral Substances are delivered to the buyer.
Such payments and statements shall be deemed conclusive and correct unless Owner objects to them in writing within 120 days
after receipt of such payments and statements. Any such objection shall specifically identify the deficiencies of
Optionee’s payment, accounting, or documentation. Optionee shall, upon not less than ten (10) days advance written
notice and during normal business hours, allow reasonable inspection by Owner’s accountant or legal representatives of
Optionee’s records, for the sole purpose of verifying compliance with the terms of this Option and correct calculation
of the Net Smelter Return Royalty payment made to Owners. Owner’s right to such inspection shall be limited to not more
than one time per year, unless an inspection by Owners reveals a substantiated noncompliance with the standards of this
Option, in which case Owners may repeat an inspection within less than twelve months.

(d)          As
used herein, the term “Mineral Substances” means commercially valuable minerals in their first saleable form as produced
by Optionee. For clarity, any value added to Mineral Substance by further refining or processing same beyond their first saleable
form shall not be included in the calculation of the Net Smelter Return Royalty, except as a workback to reach an agreed on contained
value (if necessary), If Optionee uses Mineral Substances to produce further refined or finished products, then Net Smelter Return
Royalty shall be calculated based on the price attributable to the contained value of the applicable Mineral Substances contained
in such further refined or finished products, as if such Mineral Substances were sold in their first saleable form.

 

Optionee
shall, at such time as the statement is delivered, pay to Owners the Net Smelter Return Royalty due to Owners, by wire transfer
direct into Owners’ depository bank accounts as Owners may from time to time direct. Initially the Net Smelter Return Royalty shall
be paid by Optionee to you as follows: Elda will be entitled to the entire Net Smelter Return Royalty from the minerals extracted
from the Section 27 Portion of the Real Property, plus one-half of the Net Smelter Return Royalty from the minerals extracted from
the Section 33 Portion of the Real Property, and Beverly will be entitled to one-half of the Net Smelter Return Royalty from the
minerals extracted from the Section 33 Portion of the Real Property.”

 

(i)          Notwithstanding
anything to the contrary in the Option or this Extension Agreement, the Weather Station Tower Lease dated June 10, 2014, the North
Building Lease dated May 21, 2014, and the South Building Lease dated January 1, 2011, each by and among each of you, as Lessor,
and the Company, as Lessee, including each exhibit and schedule thereto, each as extended pursuant to that Extension of Building
Lease Agreements dated as of even date herewith, shall govern the rights and obligations of each of you and the Company with respect
to the Company Leased Buildings, including the Company’s rights of use and obligations of payment of rental therefor during the
Extended Option Period, and if the Company exercises its right to purchase the Real Property, until Closing. The rental payments,
to be paid to you pursuant to the leases, are in addition to the obligation of the Company to pay you, upon Closing of the Transaction,
for the buildings as provided in paragraph 3 of Exhibit A-l.

 

5.          Payment
Terms. All dollar amounts expressed in this Extension Agreement shall be paid in United States currency. All Extension
Payments and any amount (other than the Purchase Price) due in respect of paragraph 3 of this Extension Agreement or otherwise
in respect of the Option, will be considered to have been timely made if personally received by you on or before the due date

Option to Purchase by certified or registered mail, return receipt requested, or by Federal Express or other overnight courier,
as evidenced by a receipt for certified or registered mail, or Federal Express or other overnight courier date stamp.

6.          Representations
and Warranties; No Lease or Conservation Reserve Program; Assignment and Transfer.
Elda is reaffirming that all of the representations and warranties made by Elda in the Option are to the best of her
knowledge true, accurate and complete as of the Effective Date, and Beverly joins in and makes the same representations and warranties
made by Elda in the Option, and that such representations and warranties of Beverly are to her knowledge true, accurate and complete
as of the Effective Date, provided that the Company acknowledges that as of the Effective Date (i) Elda has transferred an undivided
one-half interest in and to the Section 33 Portion of the Real Property to Beverly, and (ii) Elda has entered into, and Beverly
by her signature below agrees to be bound by, (a) an oral cash lease with Kenneth Heidemann for a portion of the Real Property
(“Heidemann Lease”) and (b) an oral cash lease with Bill Phillips fora portion of the Real Property (“Phillips
Lease”).

 

You
agree to terminate the current Heidemann Lease and current Phillips Lease prior to August 31, 2015, with such terminations to be
effective at the end of their current respective terms, which are both February 29, 2016. For the period from March 1, 2016 through
the duration of the Extended Option Period, you agree only to enter into written agricultural leases for the Real Property that
immediately terminate upon notice of exercise of the Option by the Company. Should the Company exercise the Option on or after
March 1 of a given calendar year, the Company agrees to reimburse you as landlord and your agricultural tenant for the actual amounts
expended in preparation of the land for that crop year and the value of the growing or unharvested crops on the Real Property.
Should the Company execute the Option prior to March 1 of a given calendar year, Company agrees to reimburse you as landlord and
your agricultural tenant only for the actual amounts expended in preparation of the land for that crop year. Reimbursement shall
be allocated between you as landlord and your tenant in proportion to your actual interest in the actual amounts expended in preparation
of the land, growing crops, or unharvested crops. Reimbursement for landlord of the Section 33 Portion of the Real Property shall
be payable 50% to Elda and 50% to Beverly. Reimbursement for landlord of the Section 27 Portion of the Real Property shall be payable
100% to Elda.

 

Company
also acknowledges that as of the Effective Date, a portion of the Real Property has been enrolled in the Conservation Reserve Program
or similar program, which enrollment terminates as of September 30, 2020 (“Existing CRP Enrollment”). Each of
you hereby represents and warrants that, as of the Effective Date, you each own an undivided one-half interest in and to the Section
33 Portion of the Real Property and that Elda is the sole legal, beneficial and equitable owner of all right, title and interest
in and to the Section 27 Portion of the Real Property, and that, in the aggregate, you are the sole legal, beneficial and equitable
owners of all right, title and interest in and to the Real Property and, in the aggregate, you have good and marketable fee title
in and to the Real Property and good and lawful authority to grant the Option and to enter into this Extension Agreement and to
convey the entire Real Property pursuant to the Option and this Extension Agreement.

 

Notwithstanding
anything in the Option to the contrary, each of you agree (i) that during the Extended Option Period and thereafter until Closing,
and (ii) if Company exercises its right to purchase the Real Property pursuant to the Option and elects to Close on the Transaction
and you also elect to reserve the Life Estate in accordance with the Option and this Extension Agreement, during the term of the
Life Estate, neither of you are permitted without the express prior written consent of the Company, which consent may be withheld

Transferee’s interest in the Real Property shall be subject to and be bound by the terms and conditions of the Option and this
Extension Agreement, and if such writing is not delivered by the Transferee to the Company prior to the date of such Transfer,
such Transfer shall, to the maximum extent permitted by law, be deemed null and void and with no force or effect.

9.          Effective
Date; Assignment. This Extension Agreement becomes effective as of the date of this Extension Agreement first set
forth above (“Effective Date”). The Option and this Extension Agreement, and all of the parties’ respective
obligations, rights, privileges, title and interest in, to, under and in respect of the Option, including the Addendum, and this
Extension Agreement (including, without limitation, all of the parties’ respective obligations and rights under and in respect
of paragraph 4(g) of this Extension Agreement) will be binding upon, and will inure to the benefit of and be enforceable by and
against the parties hereto and their respective assigns, trustees, successors, heirs, executors, personal representatives, legal
representatives, administrators and any subsequent owner of, or anyone holding any right, title or interest in or to, all or any
part of the Real Property. Section 8 of the Option to Purchase is hereby deleted in its entirety. Notwithstanding anything to
the contrary in the Option or this Extension Agreement, each of you agree that the right to reserve the Life Estate is personal
to each of you and the right to occupy the Life Estate Surface Area during the term of the Life Estate is personal to each of
you; and, therefore, any transfer or assignment by either of you shall not include, and you shall be prohibited from transferring
or assigning, the right to reserve the Life Estate at Closing of the Transaction in the name of any person other than either of
you.

 

10.         Counterparts.
This Extension Agreement may be executed in any number of counterparts, each of which shall be deemed an original, but all of which
together shall constitute one and the same instrument. Any executed signature page of any such counterpart, or any facsimile or
electronic PDF copy thereof, may be attached or appended by any party to any other counterpart to complete a fully executed and
original Extension Agreement.

 

11.         Effect
of Extension Agreement. All provisions of this Extension Agreement shall be in full force and effect during the
Extended Option Period and, if Optionee exercises its right to purchase the Real Property, until Closing. Except to the extent
expressly modified or amended by application of this Extension Agreement, all covenants, terms and conditions of the Option will
continue and remain in full force and effect during the Extended Option Period, and, if Company exercises its right to purchase
the Real Property pursuant to the Option, then thereafter until the Closing. For the avoidance of doubt, from and after the Effective
Date, the “Option” shall mean the Option to Purchase, dated April 30, 2010, including the Addendum and each other Attachment
thereto, as such Option is amended and extended by this Extension Agreement. In the event of any conflict between any provision
of this Extension Agreement, including Exhibit “A-l”, and the Option, the provisions of this Extension Agreement shall
control.

 

12.         1031
Exchange. In the event, in furtherance of the Transaction, either of you or the Company elect to effect a tax-deferred
exchange in conformance with Section 1031 of the Internal Revenue Code, as amended, you or the Company, having made such election,
may assign the Option and all of the electing party’s rights in, under and in respect thereof to a Qualified Intermediary as may
be necessary or appropriate for the purpose of attempting to qualify the Transaction to be eligible for treatment as a qualified
exchange allowed under Section 1031 of the Internal Revenue Code of 1986, as amended, and effecting such exchange; provided, however,
that in any such event, the Qualified Intermediary shall be bound by all covenants, agreements, warranties, representations and
all of the performance and other obligations and liabilities of the electing party under and in respect of the Option, but such
electing party nevertheless shall not be relived of, and shall remain responsible and liable for, for all of its performance and
other obligations and liabilities of the electing party under and in respect of the Option and all of the covenants, agreements,
warranties, representations and other obligations and liabilities of the electing party under and in respect thereof, all of which
shall be enforceable by and against and between you and the Company. If either of you or the Company elects to structure the Transaction
as a like-kind exchange pursuant to Section 1031 of the Internal Revenue Code of 1986, as amended, the parties will reasonably
cooperate upon the request of the electing party and shall execute any necessary documents requested by the electing party in attempting
to qualify the Transaction as an exchange under Section 1031 of the Internal Revenue Code; provided, however, that (a) the non-electing
parties shall not incur any cost or liability for its assistance (except the cost incurred by such party for its legal fees to
review any documentation) and the electing party will indemnify and hold the other parties harmless
from and against any cost, claims, expenses, or liabilities (including but not limited to reasonable attorney fees and expenses
and costs of litigation) incurred by such parties solely as a result of structuring the Transaction as a like-kind exchange, and
(b) the exchange will have no material effect on the terms of the non-electing parties’ obligations or in respect of the Option
or this Extension Agreement. Nothing contained herein shall prevent all parties from electing a like-kind exchange.

Section 11. At the time such notice is given, Optionee shall pay the Owner one thousand dollars ($1,000.00) as earnest money which
shall apply toward the Purchase Price. Upon the exercise of this Option, the purchase of the Real Property shall be governed by
the terms and conditions stated herein. Optionee shall have the right at any time within 180 days following termination or expiration
of this Option to remove any and all buildings, structures, machinery, equipment, and facilities placed on the Real Property by
Optionee.

 

5.           Anything
herein to the contrary notwithstanding, Optionee shall have the right to terminate this Option at any time prior to exercise of
the Option by giving Owner written notice of such termination. Owner shall make any claim for damages resulting from this Option

to the Real Property.

 

6.           Owner
represents and warrants to Optionee, and its successors and assigns, that, to the best of his knowledge and except as otherwise
disclosed in writing to Optionee:

 

		(i)	Owner is the sole legal and equitable owner of the Real
Property and has good and lawful authority to convey same;

 

		(ii)	the Real Property is free and clear of all leases, liens,
encumbrances and outstanding adverse claims, demands and interests, except easements of record and visible restrictions;

 

		(iii)	the execution and delivery of this Option and
the performance of this Option by Owner will not result in any breach or constitute a default (or an event which, with notice
or lapse of time, or both, would become a default) under, or give to others any rights of termination, amendment, acceleration,
cancellation, or consent, or result in the creation of a lien or encumbrance on the Real Property, pursuant to any instrument
or obligation to which Owner is a party or by which he is bound;

Owner (or his Lessee) may remain in possession of the Real Property until Optionee gives written notice to Owner that it requires
possession of the Real Property for its operations. Optionee shall give Owner six (6) months prior written notice of its intention
to take possession of the Real Property and, during such six (6) month period, Owner may remove from said Real Property any buildings,
other structures, equipment, machinery, fences (except boundary fences), fixtures or improvements. If not so removed by Owner

[**] of the appraised value of any buildings, structures, fences (except boundary fences), or other improvements to said Real
Property (excluding equipment or machinery). If Owner removes buildings, other structures, fences or improvements from said Real
Property within six (6) months after Optionee makes such election to take possession, then Optionee will pay Owner [**]  of the appraised value for such buildings, other structures, fences (except boundary fences) or improvements (excluding

rendered and shall be final and binding. The fees and expenses of such appraisers shall be borne equally by the parties.

 

C.           If

or as grazing land. The parties shall attempt to agree on a fair per acre valuation of the land as agricultural or grazing land,
without consideration for any value for minerals, and if they reach an agreement, this value shall be treated as the appraised
value. If they fail to agree within fifteen (15) days after exercise of the Option, then Optionee and Owner shall each appoint
an appraiser familiar with the property values in the area as arbitrator. Such arbitrators shall then select a third, qualified
and impartial appraiser as a third arbitrator and a written award or decision of such arbitrators shall be rendered and shall be
final and binding. The fees and expenses of the arbitrators shall be borne equally by the parties.

the event that access roads for drill sites are constructed the roads shall not be rocked, graveled or surfaced. When the exploratory
drill site activity is completed, the Optionee shall promptly cap any drill holes and restore the surface to the original condition
as nearly as reasonably practicable so that the site may be cultivated. The drill holes shall be capped at least 36 inches below
the surface so as to not interfere with any farming cultivation or operations.

for payment as deemed acceptable to Owner. Upon exercising the option to purchase for the “Mineral Rights” only, Owner
shall execute and deliver a mineral deed to the Optionee conveying all minerals of any kind whatsoever in and under the “Real
Property” with the right of ingress and egress at all times for the purpose of mining, drilling, exploring, operating, and
developing said lands for minerals of any kind whatsoever and storing, handling, transporting and marketing the same therefrom.

is understood and agreed that in the event the option to purchase is exercised by Optionee to purchase the surface and the “Mineral
Rights”, the surface and the “Mineral Rights” will be acquired in its entirety and the Optionee agrees to pay
the entire purchase amount in full to the Owner at close.

caused by its operations on the surface of the “Real Property”.

 

6.          If

The
aggregate Purchase Price to be paid by Optionee at Closing shall be:

 

1.          For
the Section 33 Portion of the Real Property, 226. 43 acres* multiplied by the greater of:

 

(a)          [**] per acre, or

 

(b)          [**] the Appraised Per Acre Value** of the Real Property at the time of the Option Exercise Date, plus

 

2.          For
the Section 27 Portion of the Real Property, 40 acres* multiplied by two and one-half (2.5) times the Appraised Per Acre Value**
of the Real Property at the time of the Option Exercise Date, plus

 

3.          [**]
of the Appraised Value*** of the residential and other building improvements located on the Real Property as of the Option Exercise
Date.

 

*          For
the avoidance of doubt, for purposes of determining the Purchase Price, the parties agree that (i) the Section 33 Portion of the
Real Property consists of 226.43 acres and (ii) that the Section 27 Portion of the Real Property consists of 40 acres, whether
such section of the Real Property actually contains more or less.

 

**         Appraised
Per Acre Value. As used in this Option, the “Appraised Per Acre Value” of the Real Property shall
be the per acre value of the Real Property at the time of the Option Exercise Date as determined in accordance with this
Exhibit “A-l”. The parties agree that in determining the Appraised Per Acre Value, consideration shall be given
only to the fair market value of the Real Property assuming the same will be used solely for agricultural purposes or grazing
land. For the avoidance of doubt, the Real Property will be valued as a whole, without giving any consideration to the fact
that different purchase values apply to the Section 33 Portion and the Section 27 Portion. Owners and Optionee shall attempt
in good faith to arrive at the Appraised Per Acre Value of the Real Property, and if they reach an agreement, such value
shall be the Appraised Per Acre Value. If they fail to agree within fifteen (15) days after the Option Exercise Date, then
Optionee and Owners (collectively) shall each appoint one appraiser familiar with real property values of similarly situated
land in Johnson County, Nebraska or the surrounding area. Such appraisers shall promptly appoint a third appraiser who also
shall be familiar with real property values of similarly situated land in Johnson County, Nebraska or the surrounding area.
Each appraiser shall promptly prepare an appraisal of the fair market per acre value of the Real Property assuming the same
will be used solely for agricultural purposes or grazing land. If Optionee and Owners cannot in good faith arrive at the
Appraised Per Acre Value by mutual agreement, then the Appraised Per Acre Value as contemplated by this Exhibit
“A-l” shall be determined by averaging the fair market per acre value of the Real Property determinations
of the two appraisers of the three appraisers appointed pursuant to this Exhibit “A-l” whose determinations of
the Appraised Per Acre Value are closest, and such average then shall be deemed to be the “Appraised Per Acre
Value” and shall be final and binding on both Optionee and Owners. The fees and expenses of the appraiser selected by a
party shall be borne by such party, and the fees and expenses of the third appraiser shall be borne equally by the
parties. Each appraiser appointed pursuant to this Exhibit “A-l” shall be required to (i) be a registered real
property appraiser (as defined in Neb. Rev. Stat., Section 76-2217.01 (as amended from time to time)) meeting the then
current minimum qualifications set forth in Neb. Rev. Stat., Section 76- 2229.01(2)(c) and (ii) hold a current designation as
a Nebraska Certified Real Estate Property Appraiser.

and Optionee shall attempt in good faith to arrive at the Appraised Value of the residential and other building improvements located
on the Real Property, and if they reach an agreement, such value shall be the Appraised Value of the residential and other building
improvements located on the Real Property. If they fail to agree within fifteen (15) days after the Option Exercise Date, the Appraised
Value of such residential and other building improvements shall be determined by the appraisers appointed to determine the Appraised
Per Acre Value. Such appraisers shall determine the Appraised Value of the residential and other building improvements using the
same methodology as established for determining the Appraised Per Acre Value, understanding however that there shall not be any
allowance for the value of the land upon which the residential and other building improvements have been erected or constructed
since Owners will be compensated for such land by application of subparagraphs 1 and 2 above.

TO

 

EXTENSION AGREEMENT BETWEEN

 

VICTOR L. WOLTEMATH AND JUANITA E. WOLTEMATH

AND ELK CREEK RESOURCES CORP.

 

Exploration Lease Agreement and Option to
Purchase

[See attached]

 

EXPLORATION LEASE AGREEMENT AND OPTION
TO PURCHASE

 

This Exploration Lease
Agreement and Option to Purchase (“Agreement”) is made this 25th day of March, 2010, by and between Victor
L. Woltemath and Juanita E. Woltemath, husband and wife whose address is 62044 720 Rd., Elk Creek, NE 68348 (“Lessor/Owner”)
and Elk Creek Resources Corp., a Nebraska Corporation, whose address is 6003 Old Cheney Road, Lincoln, Nebraska, 68516, (“Lessee/Operator”).

 

1.           PROPERTY:
The property which is the subject of this Agreement (the “Property”) is situated in Pawnee County, Nebraska and
Johnson County, Nebraska and is more fully described on Exhibit “A” attached and incorporated herein. The “Mineral
Interest” which is the subject of the Option to Purchase is situated in Pawnee County, Nebraska and Johnson County, Nebraska
and is more fully described on Exhibit “B” attached and incorporated herein. “Mineral Interest” is defined
herein to include minerals of any kind whatsoever lying in and under the Property and cobalt and all other base and precious metals
and all economic minerals, metals or substances.

 

2.           EXPLORATION
RIGHTS AND OPERATIONS: In consideration of a one-time payment of [**] per acre, the receipt and sufficiency of which is hereby
acknowledged, Lessor/Owner hereby grants to Lessee/Operator the exclusive right to explore and evaluate the Property for a period
of sixty (60) months from and after the date hereof.

 

	 	(a)	Lessee/Operator shall conduct its operations on the Property in a good and environmentally responsible manner and shall comply with all applicable laws and regulations of any governmental entity having jurisdiction over such operations including, but not limited to, laws and regulations pertaining to exploration and mining operations, mine safety and health, environmental protection and reclamation.

 

	 	(b)	Lessee/Operator shall have the right, for exploration and evaluation purposes, to build roadways on the Property. In the event that roadways are constructed on the Property, they shall not be rocked, graveled or surfaced without the consent of the Lessor/Owner.

 

	 	(c)	Lessee/Operator shall have the right to drill, develop, appropriate and devote to its own use water wells that are necessary for its operations on the Property. This right may only be established with Lessor/Owner’s consent on a case by case determination. Lessor/Owner retains the ability to refuse the right for Lessee/Operator to drill, develop, appropriate and devote to its own use water wells that are necessary for its operations on the Property, only if it is objectively unreasonable. If Lessor/Owner agrees to allow Lessee/Operator to drill, develop, appropriate and devote its use of water, all water development conducted and all water rights acquired, shall be done in accordance with Nebraska law. In the event such development should occur, at the conclusion of this “Agreement” all water rights will revert to Lessor/Owner. The Lessee/Operator agrees to conduct its operations in a manner that protects Lessor/Owner’s fresh ground water from contamination. In the unlikely event that Lessee/Operator’s operations cause fresh ground water contamination to the surface water and/or subsurface water, the Lessee/Operator shall be liable and responsible unto Lessor/Owner and Lessor/Owner’s tenant(s) for all damages suffered. It is understood and agreed that “Mineral Interest” is in no way to be construed as any interest in fresh ground water or water rights.

	 	(d)	Lessee/Operator shall pay for labor and materials supplied to it on the Property and shall keep the Property free and clear from all liens and encumbrances related to such labor and materials.

 

	 	(e)	If Lessee/Operator does not exercise its Option to Purchase, all water wells and power lines located on the Property shall become the property of Lessor/Owner upon the termination of this Agreement, provided, however, that Lessee/Operator may remove all buildings, structures, fixtures, machinery and equipment from the Property within twelve (12) months after said termination. All such buildings, structures, fixtures, machinery and equipment not removed within said twelve (12) months period shall become the property of Lessor/Owner. If Lessor/Owner does not elect to accept such buildings, structures, fixtures, machinery and equipment, then they shall be removed at Lessee/Operator’s cost.

 

	 	(f)	When the exploratory drill site activity is completed, the Lessee/Operator shall promptly cap any drill holes and restore the surface to the original condition as nearly as practicable so that the site may be cultivated. The drill holes shall be capped at least sixty (60) inches below the surface so as to not interfere with any farming cultivation or operations.

 

	 	(g)	If Lessee/Operator does not exercise its Option to Purchase, then upon the termination of this Agreement, Lessee/Operator shall provide Lessor/Owner with copies of all non-interpretative information generated during the term of this Agreement concerning the Property, which may be in Lessee/Operator’s possession or control. Lessee/Operator makes no representation or warranty of any kind as to the accuracy or completeness of such information, and Lessee/Operator shall have no liability or responsibility for the accuracy or completeness of such information.

 

	 	(h)	Lessee/Operator may remove such mineral samples, cuttings, cores or materials as are necessary or desirable for a complete evaluation of the Property. Lessee/Operator shall not, however, commence commercial mineral production or sell any mineral product from the Property unless the Option to Purchase has been exercised by the Lessee/Operator and the total purchase price of [**] per acre has been paid by Lessee/Operator to Lessor/Owner.

 

	 	(i)	Lessee/Operator agrees to pay to Lessor/Owner the sum of Five Thousand Dollars ($5,000.00) for each drill hole to be constructed on the Property which sum shall be paid prior to the undertaking of any construction activities of the drill hole. A drill hole shall be established as a hole in which mineralization has been reached being approximately four hundred feet to five hundred feet (400’-500’) in depth.

 

	 	(j)	The Lessee/Operator must comply with all applicable local, state and federal, laws, rules and regulations concerning exploration or mining activities on the Property, including requirements for posting of bonds or sureties in connection with these activities. The Lessee/Operator agrees to indemnify and hold the Lessor/Owner harmless with respect to any and all costs, claims, liabilities and expenses arising out of the Lessee/Operator’s activities on the Property.

 

	 	(k)	It is understood and agreed by the parties that if the surface acres of the Property covered by this Agreement are presently entered in the Conservation Reserve Program, (“Program”), the Property in the Program must be kept in an approved grass cover for the duration of the Program. The Lessee/Operator will indemnify and hold harmless the Lessor/Owner, or his agents, from any costs or penalties as a result of the Property not being in compliance with the Program, including but not limited to cost-shares, annual payments, interest, liquidated damages, withheld payments, penalties or any repayments to the USDA. The Lessee/Operator further agrees that it will pay all costs of restoring the Property to compliance with the Program promptly; and that in the event that any program payments are withheld, any penalties are assessed, or any repayments to the USDA are required, they will reimburse the Lessor/Owner for these withheld payments, penalties or repayments to the USDA. Prior to Lessee/Operator’s operations, the Lessee/Operator will notify the County Soil Conservation Service Office and FSA office of the exploration activity.

drilling, roadways established, structures erected, production, storage facilities or any other use or damage caused to the Property
enrolled in the Program, any repayments of cost-shares, annual payments, interest and liquidated damages, will be promptly reimbursed
to the Lessor/Owner by the Lessee/Operator.

 

3.           DAMAGES:
Drilling shall be conducted in such a manner as to cause the minimum amount of detrimental interference with the agricultural
operations on the Property. Lessee/Operator shall promptly either repair or restore or reimburse the Lessor/Owner the reasonable
value for any damage to the surface of the Property and any improvements thereon, including any cost of Property restoration and
crop or livestock damage caused by such drilling or access road construction.

 

	 	(a)	Lessee/Operator is aware that grazing livestock may be located on the Property. In the event that such livestock is located on the Property, Lessee/Operator shall act in a responsible manner around said livestock. Lessee/Operator shall be liable for any injury to the animal(s) and/or person(s) caused by the Lessee/Operator’s negligence.

 

	 	(b)	If the Lessor/Owner retains ownership of the surface of the Property the Lessee/Operator and/or its assigns shall pay for damages caused by its operations on the Property. Lessee/Operator shall be liable and responsible unto Lessor/Owner and Lessor/Owner’s tenant(s) for all damages caused by Lessee/Operator’s use, occupancy, possession and enjoyment of the Property, including, but not limited to, water contamination (surface and subsurface), and/or damages to growing crops, land, pasture grass, or livestock. Lessee/Operator shall indemnify and hold Lessor/Owner harmless as to any claims, damages, actions or causes of action related to any environmental damage or contamination caused or contributed to by Lessee/Operator subsequent to the commencement of this Agreement.

 

	 	(c)	No drill hole shall be drilled nearer than one hundred fifty feet (150’) from an existing house, barn, or other building on the Property without the prior consent of Lessor/Owner. Lessee/Operator shall consult with Lessor/Owner in regard to the route of ingress and egress on the Property for the purposes of testing, drilling, and developing the Property.

 

	 	(d)	Lessee/Operator shall not build or place structures on the surface of the Property except those ordinarily associated with drilling operations without the prior consent of Lessor/Owner. Any of Lessee/Operator’s buildings or fixtures that are necessary, will be present during mining operations and would occupy any portion of Lessor/Owner’s surface estate of the Property, shall be limited to reasonable uses such as ventilation shafts and monitoring devices. Lessee/Operator shall pay fair market value for any portion of the Lessor/Owner’s surface estate that is used for said buildings or fixtures.

 

	 	(e)	In the course of developing a mine for mining operations and/or production, the Lessee/Operator will require a main entrance to the mine, a shaft entrance or decline and a surface staging and/or storing area. In no way does this Agreement give the Lessee/Operator the right to the use, occupancy, possession or enjoyment of the Lessor/Owner’s surface estate of the Property for said purposes.

As to the leasehold Mineral Interest, Lessee/Operator will examine title and notify Lessor/Owner if, in the opinion of Lessee/Operator’s counsel, title is defective so as to substantially impair mining, or such title is contested or questioned by any person, entity or governmental agency so as to substantially impair mining. In that event, Lessee/Operator and Lessor/Owner shall take such actions as are reasonably necessary to perfect, defend, or protect title to the leasehold Mineral Interest, then Lessee/Operator may elect either to (1) close only on the “Mineral Interest” at a reduced pro rata price to be agreed upon between parties, or (2) terminate this Agreement.

 

	 	(d)	Conveyance of the “Mineral Interest” shall be at closing by a good and sufficient Mineral Deed containing warranty of title.

Conveyance of the leasehold Mineral Interest shall be by an assignment containing a warranty that Lessor/Owner shall have done nothing to impair the title to the leasehold Mineral Interest.

 

	 	(e)	Real estate taxes, leasehold costs and expenses associated with the “Mineral Interest” shall be pro-rated to the date that Lessee/Operator pays to Lessor/Owner the first One-half (1/2) of the purchase price, being [**]per acre. After said date, Lessee/Operator shall be responsible for and shall pay all real estate taxes, leasehold costs and expenses associated with the “Mineral Interest”.
