 WHEREAS, the Company has determined to issue and deliver Common Stock Purchase Warrants (the “Warrants”) entitling the holders of the
Warrants to purchase an aggregate of up to 12,000,000 Common Shares of the Company; 
 WHEREAS, the Company desires to provide for the
form and provisions of the Warrants, the terms upon which they will be issued and may be exercised, and the respective rights, limitations and immunities of the Company, the Warrant Agent and the holders of the Warrants; and 
 WHEREAS, all acts and things necessary have been done and performed to make the Warrant, when executed on behalf of the Company and countersigned
by or on behalf of the Warrant Agent, as provided in this Agreement, the valid, binding and legal obligation of the Company, and to authorize the execution and delivery of this Agreement; 
 NOW, THEREFORE, in consideration of the mutual agreements contained herein, the parties hereto agree as follows: 
 Article I 
 Execution and
Countersignature of Warrants 
 1.01. Execution and Countersignature of Warrants. 
 (a) Each Warrant, whenever issued, shall be dated             , 200_, shall be
substantially in the form of Exhibit A attached hereto and incorporated hereby, and shall be signed by, or bear the facsimile signature of, the President or a Vice President and of the Secretary or an Assistant Secretary of the Company. If any
officer whose facsimile signature has been placed upon any Warrant ceases to be that officer before the Warrant is issued, the Warrant may be issued with the same effect as if the officer had not ceased to be that officer on the date of issuance.

 (b) No Warrant may be exercised until it has been countersigned by the Warrant Agent. The Warrant Agent shall countersign a Warrant only
if: 
 (i) the Warrant is to be issued in exchange or substitution for one or more previously countersigned Warrants, as
provided in this Agreement, or 
 (ii) the Company instructs the Warrant Agent to do so. 
 (c) Unless and until countersigned by the Warrant Agent pursuant to this Agreement, a Warrant is invalid and of no effect. 

 Article II 
 Warrant Price, Duration and Exercise of Warrants 
 2.01. Warrant Price. Each Warrant,
when countersigned by the Warrant Agent, shall entitle the holder of the Warrant, subject to the provisions of this Agreement, to purchase from the Company two hundred (200) Common Shares for each Warrant as stated on the face of the Warrant at
the price of five dollars ($5.00) per share until such time prior to the expiration date as described in the Warrant, as up to 60,000 warrants have been exercised and the Company has received up to $60,000,000 in the process, subject to the
adjustments provided in Article III of this Agreement. The Warrant Price as used herein shall refer to the price per share at which Common Shares may be purchased at the time a Warrant is exercised. 
 2.02. Duration of Warrants. Warrants may be exercised only on or before the earlier date on which 60,000 Warrants have been issued or the date
that is the last Friday of the seventh calendar month after the date of issue of the Warrants (the “Expiration Date”). Notwithstanding the foregoing, if notice has been given as provided in Article III hereof in connection with the
liquidation, dissolution or winding up of the Company, the Warrants shall expire at the close of business on the third full business day before the date specified in the notice as the record date for determining holders of stock entitled to receive
any distribution upon the liquidation, dissolution or winding up; provided, however, that such date is at least five (5) business days after the date of the notice. 
 2.03. Exercise of Warrants. 
 (a) A Warrant, when countersigned by the Warrant Agent, may be exercised
by surrendering it at the office of the Warrant Agent in Cranford, New Jersey, or at the office of its successor as warrant agent, prior to the close of business of the Warrant Agent on the Expiration Date or such earlier date as may be applicable
with the exercise form set forth in the Warrant duly completed and executed, and by paying in full, in lawful money of the United States, the Warrant Price for each full Common Share as to which the Warrant is exercised, and any applicable taxes.
Notwithstanding the foregoing, the Company is only required to use reasonable efforts which will permit the purchase and sale of the Common Shares underlying the Warrants and is not required to qualify the Warrants or the Common Shares underlying
the Warrants in any state. 
 (b) As soon as practicable after the exercise of any Warrant, the Company shall issue to, or upon the order of,
the holder or holders of the Warrant, in whatever name or names the Warrant holder may direct, a certificate or certificates for the number of full Common Shares to which the holder or holders are entitled, registered in the name or names specified
by the holder or holders, and, if the Warrant is not exercised in full (except with respect to a remaining fraction of a share), a new countersigned Warrant for the number of shares (including fractional shares) as to which the Warrant has not been
exercised. All Warrants surrendered shall be canceled by the Company. 
 (c) If the same holder of one or more Warrants exercises the
purchase rights under the Warrants in the same transaction in a manner that leaves the right to purchase a fraction of a share unexercised, the Company shall pay a cash adjustment with respect to that final fraction in an amount equal to the same
fraction of the current market price of one Common Share on the business day that 

  

 2 

 
next precedes the day of exercise reduced by the same fraction of the Warrant Price of one Common Share on that day. For this purpose, the current market
price shall be the price of one Common Share on the principal stock exchange on which the Common Shares is traded on the next preceding business day, or, if no sales take place on that day or if the Common Shares are not then listed on a stock
exchange, the average of the reported bid and asked prices on that day in the over-the-counter market. 
 (d) All Common Shares issued upon
the exercise of a Warrant shall be duly and validly issued, fully paid and nonassessable, and the Company shall pay all taxes in connection with the issuance of such shares. The Company shall not be required to pay any tax imposed in connection with
any transfer involved in the issuance of a certificate for Common Shares in any name other than that of the holder or holders of the Warrant surrendered in connection with the purchase of the shares. In this case the Company shall not be required to
issue or deliver any stock certificate until the tax has been paid. 
 (e) Each person in whose name any certificate for Common Shares is
issued shall be deemed to have become the holder of record of the shares on the date on which the Warrant was surrendered and payment of the Warrant Price and any applicable taxes was made, irrespective of the date of delivery of the certificate,
except that, if the date of surrender and payment is a date when the stock transfer books of the Company are closed, a person shall be deemed to have become the holder of shares at the close of business on the next succeeding date on which the stock
transfer books are open. Except as otherwise provided in Article III, each person holding any shares received upon exercise of Warrants shall be entitled to receive only dividends or distributions which are payable to holders of record on or after
the date on which the person is deemed to become the holder of record of such shares. 
 Article III 
 Adjustments 
 3.01. Stock
Dividends - Split-Ups. If after the date of this Agreement, and subject to the provisions of Section 3.07 hereof, the number of outstanding Common Shares of the Company is increased by a stock dividend payable in Common Shares or by a
split-up of Common Shares, then, on the day following the date fixed for the determination of holders of Common Shares entitled to receive the stock dividend or split-up, the number of shares issuable on exercise of each Warrant shall be increased
in proportion to the increase in outstanding shares and the then applicable Warrant Price shall be correspondingly decreased. 
 3.02.
Aggregation of Shares. If after the date of this Agreement, and subject to the provisions of Section 3.07 hereof, the number of outstanding Common Shares of the Company is decreased by a combination or reclassification of Common Shares,
then, after the effective date of the combination or reclassification, the number of Common Shares issuable on exercise of each Warrant shall be decreased in proportion to the decrease in outstanding Common Shares and the then applicable Warrant
Price shall be correspondingly increased. 
 3.03. Special Stock Dividends. If after the date of this Agreement, and subject to the
provisions of Section 3.07 hereof, shares of any class of stock of the Company (other than Common Shares) are issued by way of a stock dividend on outstanding Common 

  

 3 

 
Shares, then, commencing with the day following the date fixed for the determination of holders of Common Shares entitled to receive the stock dividend, in
addition to any Common Share receivable upon exercise of the Warrants, the Warrant holders upon exercise of the Warrants shall be entitled to receive, as nearly as practicable, the same number of shares of dividend stock, plus any shares issued upon
any subsequent change, replacement, subdivision or combination of the stock dividend, to which the holders would have been entitled if their Warrants would have been exercised immediately prior to the stock dividend. No adjustment in the Warrant
Price shall be made merely by virtue of the happening of any event specified in this Section 3.03. 
 3.04. Reorganization, Etc.
If after the date of this Agreement any capital reorganization or reclassification of the Common Shares of the Company, or consolidation or merger of the Company with another corporation, or sale of all or substantially all of its assets to another
corporation is effective, then, as a condition of the reorganization, reclassification, consolidation, merger or sale, lawful and fair provision shall be made whereby the Warrant holders after the transaction shall have the right to purchase and
receive, upon the basis and upon the terms and conditions specified in the Warrants and in lieu of the Common Shares of the Company purchasable and receivable immediately prior to the transaction upon the exercise of the rights represented by the
Warrants, the shares of stock, securities or assets that may be issued or payable with respect to or in exchange for a number of outstanding Common Shares equal to the number of Common Shares purchasable and receivable immediately prior to the
transaction upon the exercise of the rights represented by the Warrants if the reorganization, reclassification, consolidation, merger or sale had not taken place. Appropriate provisions shall be made in connection with a reorganization,
reclassification, consolidation, merger or sale with respect to the rights and interests of the Warrant holders to the end that the provision of this Agreement (including, without limitation, provisions for adjustments of the Warrant Price and of
the number of shares purchasable upon exercise of the Warrants) shall immediately after the transaction be applicable as nearly as possible to any shares of stock, securities or assets deliverable immediately after the transaction upon the exercise
of the Warrants. The Company shall not effect any consolidation, merger or sale unless, prior to the consummation of the transaction, the successor corporation (if other than the Company) resulting from the consolidation or merger, or the
corporation purchasing the assets, assumes by written instrument executed and delivered to the Warrant Agent the obligation to deliver to the Warrant holders the shares of stock, securities or assets in accordance with the foregoing provisions that
the holders may be entitled to purchase. 
 3.05. Notice of Change in Warrant. Upon any adjustment of the Warrant Price or the number
of shares issuable on exercise of a Warrant, then and in each case the Company shall give written notice of the adjustment to the Warrant Agent. The notice shall state the Warrant Price resulting from the adjustment and the increase or decrease, if
any, in the number of shares purchasable at that price upon exercise of a Warrant, setting forth in reasonable detail the method of calculation and the facts upon which the calculation is based. The Company shall mail or cause to be mailed to each
holder of Warrants at the address registered with the Company, a notice setting forth such change or adjustment. Failure to file a statement or to give notice, or any defect in a statement or notice, shall not affect the legality or validity of the
changes or adjustments.

 3.06. Other Notices. In case at any time: 
 (a) the Company pays any dividends payable in stock upon its Common Shares or makes any distributions (other than regular cash dividends) to the holders
of its Common Shares;

of any class or any other rights; 
 (c) there is a capital reorganization, a classification of the capital stock of the Company or a
consolidation or merger of the Company with, or a sale of all or substantially all of its assets to, another corporation; or 
 (d) there is

 then, in any one or more of these cases, the Company shall give written
notice in the manner set forth in Section 3.05 of this Agreement of the date on which (i) the books of the Company close or a record is taken for the dividend, distribution or subscription rights, or (ii) the reorganization,
reclassification, consolidation, merger, sale, dissolution, liquidation or winding up takes place. The notice also shall specify the date as of which the holders of record of Common Shares shall participate in dividend, distribution or subscription
rights, or shall be entitled to exchange their Common Shares for securities or other property deliverable upon the reorganization, reclassification, consolidation, merger, sale, dissolution, liquidation or winding up. The notice shall be given and
published at least twenty (20) days prior to the transaction in question and not less than twenty (20) days prior to the record date or the date on which the Company’s transfer books are closed with respect to the transaction. Failure
to give or publish the notice, or any defect in the notice, shall not affect the legality or validity of any transaction covered or to be covered in the notice. 
 3.07. Limitation on Fractions. Notwithstanding anything in Sections 3.01 or 3.02 hereof to
the contrary, cumulative adjustments in the number of shares issuable upon exercise of Warrants shall be made only to the nearest multiple of one-tenth ( 1/10) of a share, i.e., fractions of less than five-hundredths ( 5/100) of a share shall be
disregarded and fractions of five-hundredths ( 5/100) of a share or more shall be treated as being one-tenth ( 1/10) of a share. 
 3.08. Form of Warrant. The form of Warrant need not be changed due to any change pursuant to this article, and Warrants issued after a change may state the same Warrant Price and the same number of shares as is
stated in the Warrants initially issued pursuant hereto. However, at any time in its sole discretion, the Company may make any change in the form of Warrant that it may deem appropriate and that does not affect the substance of the Warrants. Any
Warrant subsequently issued and countersigned, whether in exchange or substitution for an outstanding Warrant or otherwise, may be in the form as so changed.

Conferred by Warrants. A Warrant does not entitle its holder to any of the rights of a stockholder of the Company. 
 4.02. Lost,
Stolen, Mutilated or Destroyed Warrants. If any Warrant is lost, stolen, mutilated or destroyed, the Company and the Warrant Agent may issue a new Warrant of like denomination, tenor and date as the Warrant so lost, stolen, mutilated or
destroyed. Any such issuance of a new Warrant shall be on whatever terms and conditions with respect to indemnity or otherwise that the Company and Warrant Agent may in their sole discretion impose (which shall, in the case of a mutilated Warrant,
include the surrender of the Warrant). Any new Warrant shall constitute an original contractual obligation of the Company, regardless of whether the allegedly lost, stolen, mutilated or destroyed Warrant is at any time enforceable by anyone.

 4.03. Reservation of Common Shares. The Company shall at all times reserve and keep available the number of its authorized but
unissued Common Shares which is sufficient to permit the exercise in full of the Warrants pursuant to the terms hereof. If at any time the number of authorized but unissued Common Shares is not sufficient for these purposes, the Company shall take
such corporate action as, in the opinion of counsel, may be necessary to increase its authorized but unissued shares to the number of shares sufficient for these purposes. The Warrants, and the Common Shares issuable upon exercise of the Warrants,
have been registered under the Securities Act of 1933, as amended.

Warrant Agent in place of the Warrant Agent. 
  

 6 

 (b) If the Company fails to make an appointment within sixty (60) days after it has been notified in
writing of a resignation or an incapacity by the resigning or incapacitated Warrant Agent or by the holder of a Warrant (who must, with any notice, submit the Warrant for inspection by the Company), then the holder of any Warrant may apply to any
court of competent jurisdiction for the appointment of a successor Warrant Agent. Any successor Warrant Agent, whether appointed by the Company or by a court, must be a corporation organized, doing business and in good standing under the laws of the

 (c) After appointment, any successor Warrant Agent shall be vested with all the authorities, powers, rights, immunities, duties and obligations of its predecessor Warrant Agent with like effect as if originally named as Warrant Agent under
this Agreement without any further act or deed. However, if for any reason it becomes necessary or appropriate, the predecessor Warrant Agent shall execute and deliver, at the Company’s expense, an instrument transferring to a successor Warrant
Agent all the authority, powers, rights, immunities, duties and obligations of a Warrant Agent hereunder. Not later than the effective date of any appointment the Company shall give notice of the appointment to the predecessor Warrant Agent to each
transfer agent for its Common Shares and to the registered holders of the Warrants. Failure to give notice, or any defect in a notice, shall not affect the validity of the appointment of a successor Warrant Agent. 
 (d) Any corporation into which the Warrant Agent may be merged or with which it may be consolidated or any corporation resulting from any merger or
consolidation to which the Warrant Agent is a party shall be the successor Warrant Agent under this Agreement without any further act. 
 6.02. Fees and Expenses of Warrant Agent. The Company shall (a) pay the Warrant Agent reasonable remuneration for its services as Warrant Agent hereunder and reimburse the Warrant Agent upon demand for all expenditures that it
may reasonably incur in the execution of its duties hereunder, for example and not by way of limitation, including the cost of legal counsel utilized by Warrant Agent pursuant to Section 6.03(a) hereof; and (b) perform, execute,
acknowledge and deliver or cause to be performed, executed, acknowledged and delivered all further and other acts, instruments and assurances that reasonably may be required by the Warrant Agent to carry out or perform this Agreement.

 (a) The Warrant Agent may consult with legal counsel (who may be legal counsel for the Company) and the opinion of legal counsel shall be full and
complete authorization and protection to the Warrant Agent with respect to any action taken or omitted by it in good faith and in accordance with the opinion. 
 (b) Whenever in the performance of its duties under this Agreement the Warrant Agent deems it necessary or desirable that any fact or matter be proved or established by the Company prior to taking or suffering any

Treasurer or an Assistant Treasurer or the Controller or the Secretary of the Company and delivered to the Warrant Agent. However, in its discretion, the Warrant Agent may in lieu of a signed statement accept other evidence of a fact or matter or
may require further or additional evidence that to it may seem reasonable. 
 (i) The Company shall indemnify and hold
harmless the Warrant Agent and its employees from and against any loss, damage, liability or claim suffered, incurred by, or asserted against it or them, including expenses of legal counsel, arising out of, in connection with or based upon any act
or omission by it or them relating in any way to this Agreement or its services hereunder, so long as the Warrant Agent and its employees have acted in good faith and without negligence.

incurred by, or asserted against the Company, including expenses of legal counsel, arising out of, in connection with or based upon any act or omission by the Warrant Agent relating in any way to this Agreement or its services hereunder, so long as
the Warrant Agent has acted in bad faith and/or with negligence. 
 (c) The Warrant Agent shall not be liable for or by reason of any of the
statements of fact or recital contained in this Agreement or in the Warrants (except its countersignature of the Warrants) or be required to verify the statements or recitals, and all of these statements and recitals are and shall be deemed to have
been made only by the Company. 
 (d) The Warrant Agent shall not be responsible for (i) the validity of this Agreement, (ii) the
execution and delivery of this Agreement or the validity and execution of any Warrants (except its countersignature or execution of the Warrants), (iii) any breach by the Company of any covenant or condition contained herein or in any Warrant,
(iv) the making of any adjustment required by Article III of this Agreement or (v) the manner, method or amount of any adjustment or the ascertaining of the existence of facts that would require any adjustment. The Warrant Agent also, by
any act under or pursuant hereto, shall not be deemed to make any representation or warranty as to the authorization or reservation of any Common Shares to be issued pursuant hereto, as to any Warrant or as to whether, when issued, Common Shares
shall be duly and validly issued, fully paid and nonassessable.

and applicable regulations imposed by the Planning and Zoning Commission, and expressly insuring against the claims of any persons in possession of all or any part of the Real Property 
 D. Survey. Beginning on the Effective Date and continuing through the end of the Option Period, Optionee shall, at Optionee’s expense, have
the right to obtain an accurate ALTA survey of the Real Property satisfactory to Optionee prepared by a registered land surveyor licensed by the State of Kansas (i) showing the boundaries of the Real Property and the locations of all easements,
rights-of-way, curb cuts, structures and other improvements, encroachments, overlaps, bodies of water, officially designated flood hazard areas, nearest public street or highway, public utilities, and building set-back lines on, under or affecting
the Real Property, if any, (ii) showing the adjoining property owners, (iii) staking the corners of the Real Property with permanent iron stakes, (iv) containing a complete legal description of the Real Property, (v) certifying
the exact acreage and the exact square footage of the Real Property, exclusive of any portion used or dedicated for public rights-of-way, which shall be used to determine the Purchase Price, and (vi) stating whether all or any part of the Real
Property lies within a flood hazard area (the “Survey”). In all other respects, the Survey shall meet the requirements of any governmental agency having jurisdiction over the Real Property and any requirements of the title insurance
company of Optionee and Optionee’s lender necessary to comply with any and all applicable regulations. 
  

	 	5.	Closing; Conveyance 

 A. Closing. If Optionee
exercises the Option, the closing on the purchase of the Real Property by Optionee from Optionor shall occur within sixty (60) days from the date of the exercise of the Option by the Optionee (the “Closing”), at a time and place that
is mutually agreed upon by Optionor and Optionee. 
 B. General Warranty Deed. Upon the exercise of the Option, the Optionor shall
execute, acknowledge, and deliver to Optionee, at Closing, a good and sufficient general warranty deed conveying fee simple title to the Real Property and all improvements thereon, free and clear of all liens, encumbrances, and other defects in
title. If a defect in the title to the Real Property is identified by Optionee pursuant to Section 4(C) and Optionor agrees to cure said defect(s), all costs and expenses of curing such defects in the title shall be borne by the Optionor, and
any such costs and expenses, together with all moneys required for the satisfaction of delinquent taxes, liens, or encumbrances, may be subtracted from the Purchase Price and applied directly to the curing of such defects, if any, and to the
satisfaction and release of such taxes, liens, and encumbrances. In the event Optionor refuses to cure any title deficiencies 

  

 3 

 
identified pursuant to Section 4(C), but Optionee nonetheless proceeds to close the transaction, all costs and expenses of curing such defects in the
title shall be borne by the Optionee excepting that the cost of curing delinquent taxes, liens and encumbrances shall remain Optionor’s responsibility. Optionee acknowledges that a pipeline currently exists on and across the Real Property and
that the presence of said pipeline is an acceptable exception to the status of the title to the Real Property. 
 C. Real Property
Taxes. All real property ad valorem taxes and assessments against the Real Property for the then current tax year shall be prorated between Optionor and Optionee as of the date of Closing; such taxes shall be estimated in accordance with the
taxes assessed against the Real Property for the tax year prior to the year in which the Closing occurs. 
 In compliance with Kansas law,
Optionor hereby discloses to Optionee that to the best of Optionor’s knowledge, the Real Property is not subject to special assessments and is not located in an improvement district. 
 D. Closing Costs. Optionee shall pay the recording fee for the deed and any documents relating to Optionee’s financing of the Purchase Price,
if any. Except as provided otherwise, Optioner and Optionee will share equally in the costs of Closing. All title examination fees and title insurance premiums necessary to provide Optionee with an owner’s policy of title insurance and
Optionee’s lender, if applicable, with a loan policy of title insurance shall be paid 50% by Optioner and 50% by Optionee, except Optionee shall pay the costs of all endorsements requested by Optionee or its lender. Optionor and Optionee shall
each be responsible for the payment of their own attorneys’ fees and expenses. If upon the Closing of the purchase of the Real Property, any crops on the Real Property are damaged such that the proceeds from the harvest of such crops cannot be
paid to Optionor, Optionee shall be required to reimburse Optionor for such crop damage at the fair market value of such crops so damaged as of the Closing Date. 
 E. Affidavit of Title. Optionor shall deliver to Optionee at Closing an affidavit of title sufficient to allow the title insurance company of Optionee and Optionee’s lender, if applicable, to insure
against any and all standard exceptions, including mechanics’ liens and materialmen’s liens, and rights of all parties, other than Optionor and Optionee, to possession of all or any part of the Real Property and addressing such other items
as the title insurance company shall reasonably request. 
 F. Non-Foreign Status Certification. Optionee shall deliver to Optionor a
non-foreign status certification as required by Section 1445 of the Internal Revenue Code of 1986, as amended. 
 G. Possession.
Possession of the Real Property shall be delivered to Optionee at Closing. 
  

	 	6.	Risk of Loss 

 All risk of loss with respect to the
Real Property shall remain with Optionor until the Closing and delivery of the deed to Optionee. 
  

 4 

	 	7.	Restriction on Sale/Recordability 

 Optionor agrees
not to sell or offer for sale, transfer, convey, lease, assign, gift or otherwise dispose of the Real Property or any interest therein during the Option Period except that Optionor may elect to transfer the Real Property to an entity or to
individuals who will comply with, and be bound by, this Agreement and who shall have an identity of ownership with Optionor; Optionor and Optionee further agree that a Memorandum of this Agreement in substantially the form on Exhibit ‘B’
attached hereto shall be recorded in the Office of the Register of Deeds of Harvey County, Kansas. Should this Option be released at any time due to non-exercise or default on the part of Optionee, Optionee shall have the obligation to release its
Option claim of record with the Register of Deeds of Harvey County, Kansas, at Optionee’s sole cost and expense. 
  

	 	8.	Default 

 If either party defaults in the
performance of its duties or obligations under this Agreement, then: 
 A. if Optionee is in default, then Optionor may: (i) terminate
this Agreement and receive the Deposit as liquidated damages, thereby releasing the parties from this Agreement or (ii) pursue any other remedy available at law, in equity or by statute; and 
 B. if Optionor is the party in default, then Optionee may (i) terminate this Agreement and receive a refund of the Deposit, thereby releasing the
parties from this Agreement or (ii) pursue a legal action only for specific performance. 
  

	 	9.	Miscellaneous 

 A. Benefit and Binding
Effect. This Agreement shall be binding upon, and shall inure to the benefit of, the parties hereto, their respective heirs, legal representatives, successors and assigns. 
 B. Time of the Essence. Time is of the essence for this Agreement. 
 C. Assignment. Optionee may assign this Agreement prior to Closing to either an existing or to-be-formed legal entity for the purpose of acquiring title to the subject Real Property. 
 D. Entire Agreement. This Agreement contains the entire agreement between the parties hereto and no modification or amendment shall be binding
upon any party unless made in writing and signed by each of the parties hereto. 
 E. Governing Law. This Agreement and the rights and
obligations of the parties hereto shall be construed in accordance with the laws of the State of Kansas. 
  

 5 

 F. Counterparts. This Agreement may be executed in one or more counterparts each of which shall
constitute an original and all of which together shall constitute but one and the same instrument binding on all the parties. 
 G. Broker
Commissions. Optionor and Optionee warrant to each other that no broker has been engaged in regard to the sale of the Real Property and that no commissions will be owing to anyone in regard to this Agreement or the closing of the purchase of the
Real Property. In the event of a breach of the foregoing warranty, the breaching party agrees to save, defend, indemnify and hold harmless the other party from and against any claims, losses, damages, liabilities and expenses, including but not
limited to, attorneys’ fees. 
 H. Section 1031 Exchange. Optionee agrees, at no cost, expense, liability or obligation to
Optionee, to cooperate with Optionor to complete a tax-free exchange under Section 1031 of the Internal Revenue Code of 1986, as amended, and the Regulations promulgated thereunder, as amended, upon any sale of the Real Property by Optionor to
Optionee. 
 IN TESTIMONY WHEREOF, witness the signatures of Optionor and Optionee as of the date first above written.
