so long as Weatherford is using best efforts to obtain rail cars and minimize the period of time during which Weatherford is unable to take delivery of Products; provided, further, however, that
nothing in this sentence shall be construed to relieve Weatherford of its obligations to make payments under this Agreement (including the obligation to make any Makewhole Payments as contemplated in this Section 2.3). The Minimum
Purchase Requirement shall be ordered by Weatherford in installments of not less than 15,000 tons of Product per calendar month (the “Monthly Minimum Requirement”), and not more than the Monthly Maximum Supply Availability, beginning in
July of 2011 and continuing thereafter for each calendar month during the Term. In the event that Weatherford fails to purchase one twelfth (1/12) of the Minimum Purchase Requirement of Product from Supplier during any particular calendar month
in which Supplier was ready, willing and able to deliver 30,000 tons of Product, then the “Purchase Shortfall” shall be the amount by which one twelfth (1/12) of the Minimum Purchase Requirement exceeds the amount of Product actually
purchased by Weatherford during such calendar month. On written notice of such Purchase Shortfall to Weatherford by Supplier, Weatherford shall have *** after the month of the Purchase Shortfall to purchase tonnage of Product in excess of the
Monthly Minimum Requirement (but subject to the Monthly Maximum Supply Availability) to make up for the Purchase Shortfall. If Weatherford fails to purchase the full amount of the Purchase Shortfall in such *** period, Weatherford shall be obligated
to pay to Supplier an amount equal to the amount of the Purchase Shortfall not purchased by Weatherford in such *** period (expressed in tons) multiplied by $*** (the “Makewhole Payment”). The Makewhole Payment shall be paid within *** of
written demand by Supplier, by wire transfer of immediately available funds to the account designated in writing by Supplier. The aggregate Purchase Shortfall amount for a Contract Year shall not exceed the Minimum Purchase Requirement for such
Contract Year less the amount of Product ordered and delivered to Weatherford. Weatherford reserves the right to resell goods purchased from Supplier if deemed necessary by Weatherford in order to satisfy the Minimum Purchase Requirement. Supplier
shall not be obligated to deliver more than the Monthly Maximum Supply Availability on any given calendar month. 

  

	2.4	Forecast of Demand. Weatherford shall provide, on a quarterly basis, a non-binding 3-month rolling volume forecast of its anticipated purchase of
Products (“Forecast Amount”). Updates to the Forecast Amount indicated in the six-month rolling volume forecast will be made and communicated periodically outside of the three-month rolling volume forecast as promptly as practicable after
Weatherford becomes aware of such changes. Supplier shall notify Weatherford within ten (10) Business Days of receiving a forecast or update if Supplier anticipates being unable to meet the anticipated purchase amounts. Supplier shall not be
obligated to deliver more than the Monthly Maximum Supply Availability on any given calendar month. 

  

	2.5	Title and Risk Of Loss. All Products will be shipped FOB, Supplier’s facility located in Wyeville, Wisconsin or at the Adams Rail Facility in
Adams, Wisconsin, at the Readsberg Rail Facility in Readsberg, Wisconsin, or at a similar rail location in Wisconsin (collectively “Supplier’s Facility”), as determined by Supplier in its reasonable discretion. Title and risk of
loss or damage to Products shall pass to Weatherford at the time the Products are delivered to the carrier. Supplier is not responsible for unfilled orders resulting from any shortage or lack of availability of rail cars for shipment of orders
except that Supplier must always meet the Minimum Supply volumes as specified in Section 2.1. Supplier warrants clear title to the Products at the time title to the Products passes to Weatherford, free from any and all liens or other
encumbrances. Supplier is responsible for properly loading the Product on the nominated carrier, at its expense, and will comply with any documentary instructions of Weatherford in the shipment process.

Weatherford from time to time under this Agreement; provided that Supplier shall be under no obligation to supply or sell, and Weatherford shall not have the right to buy Products in excess of the Minimum Purchase Requirement or the Monthly Maximum
Supply Availability. This Agreement shall control and govern all transactions between the Parties with respect to the sales and purchases of Products, whether under subsequent verbal and/or written Work Orders, unless subject to an express, duly
executed agreement (which is not a pre-printed form, terms contained on an Internet site or order confirmation) for the particular subject matter. The terms of this Agreement shall prevail over the terms in the Work Order in the event of a conflict
unless specific reference and identification is made to the provision of this Agreement to be modified and the intention to modify is explicitly stated and signed by both Parties. Such changes shall be effective for that Work Order only. Printed
terms and conditions contained in documents issued to Weatherford by Supplier or from Weatherford to Supplier with respect to the Products shall be of no force and effect and shall be superseded by the terms and conditions which are contained in
this Agreement. No waiver by either Party of any of the terms, provisions or conditions hereof shall be effective unless said waiver shall be in writing and signed by an authorized officer of such Party and specifically referencing this Agreement.
Supplier agrees to promptly process all of Weatherford’s orders under the terms of this Agreement. 

  

	2.7	Delivery. Supplier agrees that all Products ordered by Weatherford will be delivered to Weatherford per this Article 2 no later than the
delivery date specified in this Agreement, subject to the Monthly Maximum Supply Availability.

	 	(b)	Should Weatherford fail to make an adjustment to an invoice to which it was entitled, and as a result has overpaid amounts due to Supplier, then upon such overpayment
becoming known and agreed to by the Parties, Supplier shall issue a credit to Weatherford within ***, which credit may be applied by and utilized by Weatherford against future invoices owing to Supplier and, to the extent any credit has not been
applied or utilized within *** from the date of such overpayment, Supplier shall, upon demand received from Weatherford, immediately refund such remaining credit amount.

other charges, including but not limited to those relating to state and federal environmental and energy laws and regulations, assessed by any governmental entity relating to the severance, manufacture, sale or delivery of the Product shall be for
Weatherford’s account, and Weatherford hereby agrees to pay such other charges. The provisions of this Section shall continue after termination of this Agreement.

	 	(a)	The following terms apply to any claim of infringement of any United States patent, by a third party arising out of or relating to a Product furnished to Weatherford by
Supplier under this Agreement (an “Infringement Claim”). Supplier shall indemnify and hold Weatherford harmless from any Damage resulting by reason of an Infringement Claim relating to a Product furnished by Supplier. Subject to
Section 5.8(b), Supplier shall defend or settle, at its own expense, any action or suit against Weatherford with respect to an Infringement Claim for which it is responsible. Weatherford shall promptly notify Supplier of any Infringement
Claim and shall reasonably cooperate with Supplier at Supplier’s expense to facilitate the defense of each claim. 

  
 pg. 12

	 	(b)	Supplier’s obligations under Section 5.8(a) shall not apply to the extent that an Infringement Claim relates to, arises or results from, or is due to
(i) Weatherford’s modification of a Product or use of a Product in combination with any other device and the Infringement Claim would not have arisen in the absence of that modification or combination; (ii) Supplier’s compliance
with designs or specifications of Weatherford; or (iii) Weatherford’s continued use of the allegedly infringing Product after being notified by the Supplier to cease such use. In the event of an act or omission by Weatherford described in
this Section 5.8(b), Weatherford shall indemnify and hold Supplier harmless from any Damage resulting from such act or omission. 

  

	5.9	International Laws. The Parties agree to comply in all respects with the applicable international and national laws that apply to the Products including,

The Parties shall provide information concerning the technical specifications of the Products and/or the use of the Products in order for the respective Parties to determine the legality of such Products and such information shall be stated in
writing as the Parties may request. 

  

	5.10	Survival of Article 5. Notwithstanding anything to the contrary, the provisions of this Article 5 shall survive any termination of this

 6. Force Majeure 
  

	6.1	Force Majeure Events. If either Party is affected by Force Majeure it shall promptly notify the other Party of the nature and extent of the circumstances
in question. Neither Party shall be deemed to be in breach of this Agreement, or otherwise be liable to the other, for any delay in performance or the non-performance of any of its obligations under this Agreement, to the extent that the delay or
non-performance is due to any Force Majeure, and the time for performance of that obligation shall be extended accordingly; provided, that if the Force Majeure in question prevails for a continuous period in excess of thirty (30) days, the
Parties shall enter into discussions with a view to alleviating its effects, or to agreeing upon such alternative arrangements as the Parties mutually agree. 

 

	6.2	Limitation. Notwithstanding Section 6.1, neither Party shall be relieved of its obligations to make payments as provided herein (including,
but not limited to, the obligations to pay for delivered Products as required hereunder). 

  

	7.	Duration and Termination 

  

	7.1	Term. This Agreement shall be deemed to become effective on the Effective Date and shall continue in effect through July 31, 2014 (such period being
referred to herein as the “Primary Term”), unless earlier terminated as provided herein. This Agreement may be extended beyond the Primary Term by mutual written agreement of the Parties.

 SPECIFIC TERMS IN THIS EXHIBIT HAVE BEEN REDACTED BECAUSE CONFIDENTIAL TREATMENT OF THOSE TERMS HAS BEEN
REQUESTED. THE REDACTED MATERIAL HAS BEEN SEPARATELY SUBMITTED TO THE SECURITIES AND EXCHANGE COMMISSION, AND THE TERMS HAVE BEEN MARKED AT THE APPROPRIATE PLACE WITH THREE ASTERISKS (***). 

 
  

	7.2	Termination by Weatherford. This Agreement may be immediately terminated for breach if Supplier fails to produce and deliver Products that meet the
Specifications for a period of more than ***. Upon such breach, Weatherford may terminate this Agreement immediately by giving written notice of termination to Supplier. Subject to fulfilling its obligations to purchase the Minimum Purchase

prior to the end of such *** period, then Supplier may terminate this Agreement immediately. 

  

	7.4	Termination of Work Order. A termination of a Work Order does not terminate this Agreement. A termination of this Agreement does not terminate any
existing Work Order until such Work Order is completed, unless such Work Order is expressly terminated also. 

  

	7.5	Events Upon Termination. 

  

	 	(a)	Upon expiration of this Agreement or the termination of the Agreement for reasons other than pursuant to Section 7.2, Weatherford shall purchase from

	 	(b)	Upon expiration of this Agreement or the termination of this Agreement for any reason, Supplier shall forthwith cease to use, either directly or indirectly, any of the
Weatherford Intellectual Property and forthwith return to Weatherford all Weatherford Intellectual Property and Weatherford Confidential Information, and Weatherford shall forthwith cease to use, either directly or indirectly, any of the Supplier
Intellectual Property and forthwith return to Supplier all Supplier Intellectual Property and Supplier Confidential Information except to the extent necessary to use the Products theretofore supplied by Supplier hereunder. In such case Supplier

obligations that are expressly stated to survive the expiration of the Term or termination of this Agreement and any obligations that remain executory (other than minimum purchase obligations), which obligations, to the extent they remain executory,
shall remain in full force and effect until fully performed by the obligated Party as stated in this Agreement. The respective Parties’ obligations under Section 3.1, Section 4.4, Article 5, this
Section 7.5 and Articles 8 through 13 shall survive the expiration of the Term or termination of this Agreement. Neither expiration nor termination of this Agreement shall relieve any Party of liability for breaches of this
Agreement prior to such expiration or termination.

	8.2	Weatherford’s Representations. Weatherford hereby represents and warrants as follows: 

 

	 	(a)	Weatherford is duly incorporated and existing in good standing in its jurisdiction of incorporation and has the full corporate power and authority to conduct its

	8.3	Indemnification of Weatherford. SUPPLIER AGREES TO INDEMNIFY, DEFEND AND HOLD WEATHERFORD AND ITS SUCCESSORS AND ASSIGNS HARMLESS FROM

 pg. 16

	8.5	Express Negligence. THE INDEMNITIES SET FORTH IN THIS ARTICLE ARE INTENDED TO BE ENFORCEABLE AGAINST THE PARTIES IN ACCORDANCE WITH THE
EXPRESS TERMS AND SCOPE THEREOF NOTWITHSTANDING TEXAS’ EXPRESS NEGLIGENCE RULE OR ANY SIMILAR DIRECTIVE THAT WOULD PROHIBIT OR OTHERWISE LIMIT INDEMNITIES BECAUSE OF THE SIMPLE NEGLIGENCE (WHETHER SOLE, CONCURRENT, ACTIVE OR PASSIVE) OR OTHER
FAULT OR STRICT LIABILITY OF ANY OF THE INDEMNIFIED PARTIES. 

  

	8.6	Indemnification Procedure. In the event either Party learns of any claim, liability, demand or cause of action relating to this Agreement or the
performance hereunder, which said Party shall determine, in its sole discretion, that the other Party may be liable therefor, said Party shall promptly notify the other Party. If indemnity is required by any of the terms of this Agreement, the
indemnifying Party shall have the right to control all litigation and shall defend the other and pay all settlements, judgments, costs, and expenses (including without limitation court costs and reasonable attorneys’ fees), whether related or
unrelated, similar or dissimilar to the foregoing, incident thereto. Each Party, if requested, agrees to cooperate with the other in any defense, and the indemnifying Party shall reimburse the other for all reasonable expenses incurred in connection
therewith. The indemnified Party shall have the right to have counsel of its own choosing and at its sole expense participate in any such litigation. Notwithstanding the foregoing, however, neither Party shall effect settlement of or compromise any
such claim or proceedings without having obtained the prior written consent of the other Party, which consent shall not be unreasonably withheld, conditioned or delayed; provided that the indemnifying Party may settle or compromise any such claim if
the settlement or compromise (a) requires solely the payment of money damages by the indemnifying Party, and (b) includes as an unconditional term thereof the release by the claimant or the plaintiff of the indemnified Party from all
liability in respect of such claim. If the indemnified Party does not consent to a settlement which the indemnifying Party is willing to accept, then the indemnifying Party’s liability shall be limited to the amount for which the claim could

and equipment or business interruption, loss of a well, loss of a producing formation, loss of production; punitive, indirect, incidental or consequential damages, or, including without limitation, any other consequential damages of whatever nature,
howsoever same may be caused; provided that this Section 8.7 shall not limit Damages recoverable for breaches of the provisions of Articles 2 or 3. 

 

	8.8	 Compliance with Law. Subject to the limitations of this Agreement, it is agreed that in the performance of this Agreement all matters
shall be conducted in full compliance with any and all applicable federal, state, provincial and local laws, rules and regulations in the area(s) in which the matters are being conducted. Any performance obligation arising under this Agreement is
contingent on the prior receipt of all necessary government authorizations. If either Party is required to pay any fine or penalty or is subject to a claim from the other Party’s failure to comply with applicable laws, rules or regulations, the
Party failing to 

  
 pg. 17

	 	
comply shall defend, indemnify and hold harmless the other Party for all damages, fees and/or fines for such failure to comply to the extent of the indemnifying Party’s allocable share of
the failure to comply.

Convention on Combating Bribery of Foreign Public Officials in International Business Transactions, signed in Paris on December 17, 1997 (“the Convention”), and the Convention’s Commentaries (collectively the “OECD
Principles”), and shall comply with all applicable laws implementing the OECD Principles (including the U.S. Foreign Corrupt Practices Act of 1977), as well as any applicable local laws related to anti-corruption, anti-kickbacks, and anti-money
laundering. Supplier agrees not to take or fail to take any action that might cause Weatherford to be in violation of any such laws. In addition to the foregoing, Supplier represents and warrants that it and its Affiliates have not and shall not
request, induce, make, offer, authorize, promise to make any payment or transfer anything of value, directly or indirectly, (a) to any governmental official or employee (including employees of government-owned or government-controlled
corporations, agencies or bodies), (b) any official or employee of a public international organization, (c) to any political party, official of a political party or candidate, or (d) to any third party knowing, believing, or
suspecting that such third party will give the payment, or any portion thereof, to any of the foregoing persons in order to obtain or retain business, or for any other improper purpose. Any payments to governmental officials or employees on behalf
of Weatherford must be promptly reported to Weatherford. 

  

	8.10	Code of Conduct/ Gifts, Entertainment and Travel. It is considered to be in conflict with Weatherford’s interest for its employees or any member of
their immediate family to accept gifts, payments, extravagant entertainment, services, or loans in any form from anyone soliciting business, or who may already have established business relations with Weatherford. Gifts of nominal value and
entertainment, meals, and social invitations that are customary and proper under the circumstances and that do not place the recipient under any obligation are acceptable. Any gifts, payment of individual expenses, including, without limitation,
trips, or conveyances to Weatherford employees shall be disclosed in writing to the Weatherford Ethics and Compliance Group. 

  

	8.11	Information Requests. Supplier shall maintain full and complete accounting records of activity performed and expenditures incurred by Supplier in
connection with this Agreement in such a manner and detail as to permit verification of compliance with the provisions of Sections 8.8 through 8.10. Weatherford shall have the right to audit such Supplier’s records for a period of
two (2) Years from the expiration or termination of this Agreement. This provision shall survive expiration or termination of this Agreement. 

 Notwithstanding anything to the contrary, neither Party shall be required to take or refrain from taking any action prohibited or penalized under the laws of the United States, including the U.S.
antiboycott laws. 
  

	8.12	 Economic Sanctions and Export Controls. Supplier agrees to fully comply with all economic sanctions and export control laws and
regulations, including those regulations maintained by the U.S. Commerce Department’s Bureau of Industry and Security and the U.S. Treasury Department’s Office of Foreign Assets Control. In addition, Supplier shall

  
 pg. 18

	 	
not, directly or indirectly, sell, provide, export, re-export, transfer, divert, loan, lease, consign or otherwise dispose of any Weatherford equipment, product, services, software, source code,
technical data or technology to or via any person, entity or destination, or for any activity or end-use restricted by the laws or regulations of the United States or any other applicable jurisdiction (including nuclear, missile, chemical or
biological weapons proliferation, military, or money laundering activities) without first obtaining all required government authorizations. 

 9. Nature of Agreement 
  

	9.1	Assignment. Either Party shall have the right to assign or transfer to any Person any of its rights or obligations under this Agreement without the prior
written consent of the other Party, provided that the assigning Party shall remain liable to the other Party under the terms of this Agreement notwithstanding such assignment. This Agreement shall be binding on and inure to the benefit of the
Parties and their respective successors and permitted assigns, including any successor upon a sale or change of control of a Party. This Agreement is intended solely for the benefit of the Parties and their respective successors and permitted
assigns. 

  

	9.2	Relationship. Each of the Parties is an independent contractor with respect to the other and is not an employee of the other Party or any of the other
Party’s Affiliates, and nothing in this Agreement is intended to constitute a partnership or a master and servant relationship between the Parties. Each of the Parties understands and agrees that this Agreement does not create an exclusive
dealings arrangement and that each of Weatherford and Supplier may enter into similar arrangements with other companies with respect to similar or the same products. Nothing in this Agreement shall be construed to create any duty to, or standard of
care with reference to, or liability of a Party to, any person not a Party to this Agreement. Nothing in this Agreement shall be deemed to constitute any fiduciary or special relationship or duty between the Parties and each Party may take actions
hereunder that are for its own self-interest without any duty or, subject to the express terms of this Agreement, liability to the other Parties. 

  

	9.3	Entire Agreement; Amendment. This Agreement, including its appendices, exhibits and schedules, constitutes the entire Agreement between the Parties with
respect to the subject matter hereof and supersedes any existing agreements between them whether oral or written. The terms of this Agreement shall only be amended, modified or supplemented as set forth herein or in a writing signed by or on behalf
of both or the Parties. In case of a conflict between this Agreement and a purchase order (Work Order) or purchase order confirmation contemplated hereunder, the terms of this Agreement shall govern. Acceptance of a Work Order or purchase order
confirmation is insufficient to amend this Agreement unless a separate writing is duly executed by all the Parties specifically amending this Agreement. 

  

	9.4	 Reformation. If any term or other provision of this Agreement is invalid, illegal or incapable of being enforced by any rule of law or
public policy, all other conditions and provisions of this Agreement shall nevertheless remain in full force and effect so long as the economic and legal substance of the transactions contemplated hereby are not affected in any manner materially
adverse to any Party. Upon the determination that any term or other provision is invalid, illegal or incapable of being enforced, the Parties shall negotiate in good faith to modify this Agreement so as to effect the original intent of the Parties
as 

  
 pg. 19

	 	
closely as possible in an acceptable manner to the end that transactions contemplated hereby are fulfilled to the extent possible. In the event any such provision, clause, sentence or part of
this Agreement cannot be modified to comply with the law, then said provision, clause, sentence or portion of the Agreement shall be deemed to be deleted from the Agreement and the remaining terms and conditions shall remain in full force and
effect. 

 10. Notices and Service 

 

	10.1	Addresses. All notices, requests, consents, directions and other instruments and communications required or permitted to be given under this
Agreement shall be in writing and shall be deemed to have been duly given if delivered in person, by courier or by overnight delivery service with proof of delivery addressed to the respective Party at the address set forth below, or if sent by

 11. General 
  

	11.1	Waiver. No failure or delay by either Party in exercising any of its rights under this Agreement shall be deemed to be waiver of that right, and no waiver
by either Party of a breach of any provision of this Agreement shall be deemed to be a waiver of any subsequent breach of the same or any other provision. 

  

	11.2	Costs. The Parties shall bear their own costs of, and incidental to, the preparation, execution and implementation of this Agreement.

  

	11.3	 Counterparts. This Agreement may be executed in one or more counterparts, each of which shall for all purposes be deemed to be an
original and all of which shall constitute the same instrument. The exchange of copies of this Agreement and of signature pages by facsimile transmission (whether directly from one facsimile device to another by means of a dial-up connection or
whether otherwise transmitted via electronic transmission), by 

  
 pg. 20

	 	
electronic mail in “portable document format” (“.pdf”) form, or by any other electronic means intended to preserve the original graphic and pictorial appearance of a document,
or by a combination of such means, shall constitute effective execution and delivery of this Agreement as to the Parties and may be used in lieu of an original Agreement for all purposes. Signatures of the Parties transmitted by facsimile or other
electronic transmission shall be deemed to be original signatures for all purposes. Minor variations in the form of signature pages of this Agreement, including footers from earlier versions of this Agreement, shall be disregarded in determining a
Party’s intent or the effectiveness of such signature. 

 12. Governing Law and Venue 

 

	12.1	Governing Law; Venue; Waiver of Jury Trial. This Agreement shall be governed by and construed and enforced in accordance with the internal laws of the
State of Texas, without giving effect to that state’s conflicts of laws principles or choice of law rules. The Parties agree that Houston, Harris County, Texas, shall be the exclusive forum and venue for resolving any disputed matter.

 BOTH PARTIES AGREE THAT, TO THE EXTENT ALLOWED BY THE GOVERNING LAW, EACH PARTY HEREBY WAIVES ALL RIGHTS
TO A JURY TRIAL WITH RESPECT TO ANY LITIGATION INVOLVING THIS AGREEMENT. 
 It is the intent of the Parties to exclude
the application of the United Nations Convention on Contracts for the International Sale of Goods (1980). Nothing herein shall prohibit a Party from availing itself of a court of competent jurisdiction for the purpose of injunctive relief. The
Parties acknowledge and agree that the Parties may have available to them laws or remedies available under applicable local legislation; it is the intent of the Parties to have the terms of this Agreement apply in every instance, including, without
limitation, the choice of law provisions. 
 13. Special Provisions 

 

	13.1	Miscellaneous. This Agreement sets forth the entire agreement between Weatherford and Supplier with respect to its subject matter. All prior
negotiations and dealings regarding the subject matter hereof are superseded by and merged into this Agreement. No modification of this Agreement shall be effective unless made in writing and signed by both Parties.

 TRANSFER OF RIGHTS IN THE PROPERTY 
 This Security Instrument secures to Lender: (a) the Secured Obligation; and (b) the performance of Borrower’s and Grantor’s covenants and agreements under the Agreement and this
Security Instrument, respectively. For this purpose, Grantor does hereby mortgage, grant and convey to Lender, the following described property: Grantor’s right, title and interest in and to the unmined or unprocessed sand representing tonnage
equivalent to the then outstanding amount of unmined or unprocessed sand owing by Borrower as the Secured Obligation (collectively, the “Secured Sand”) located at that certain real property situated in MONROE COUNTY, WISCONSIN and
more particularly described on Exhibit A attached hereto (the “Land”); 
 TOGETHER WITH all
proceeds and products of the Secured Sand (collectively, the “Proceeds”). All replacements of and additions to such Proceeds shall also be covered by this Security Instrument. The Secured Sand and the Proceeds are sometimes
hereinafter collectively referred to as the “Property”. As a point of clarity, this Security Instrument is not conveying to Lender, and the Property does not include, any of Grantor’s interests in the Land or any other real
property rights other than the Secured Sand thereon or thereunder. 

  
 2 

 GRANTOR COVENANTS that Grantor is lawfully seized of the Property hereby conveyed and has
the right to mortgage, grant and convey the Property and that the Property is unencumbered, except for encumbrances of record and encumbrances depicted on that certain survey of the Land by Vierbicher Surveyors, dated December 10, 2010
(collectively, the “Permitted Encumbrances”). Grantor warrants and will defend generally the title to the Property against all claims and demands, subject to Permitted Encumbrances. 

THIS SECURITY INSTRUMENT combines uniform covenants for national use and non-uniform covenants with limited variations by jurisdiction to
constitute a uniform security instrument covering real property. 
 UNIFORM COVENANTS. Grantor and Lender covenant and agree as
follows: 
 1. Charges; Liens. Grantor shall pay all taxes, assessments, charges, fines, and impositions attributable to the
Property which can attain priority over this Security Instrument, leasehold payments, assessments or ground rents on the Property, if any. If Lender determines that any part of the Property is subject to a lien that can attain priority over this
Security Instrument, Lender shall give Grantor a notice identifying the lien. Within 10 days of the date on which such notice is given, Grantor shall satisfy and discharge such lien, including without limitation by taking one or more of the actions
set forth above in this Section 1. 
 2. Protection of Lender’s Interest in the Property and Rights Under this Security
Instrument. If (a) Grantor fails to perform any of the covenants and agreements contained in this Security Instrument, (b) there is a legal proceeding that might significantly affect Lender’s interest in the Property and/or rights under
this Security Instrument (such as a proceeding in bankruptcy, probate, for condemnation or forfeiture, for enforcement of a lien which may attain priority over this Security Instrument or to enforce laws or regulations), or (c) Grantor has
abandoned the Property, then Lender may do and pay for whatever is reasonable or appropriate to protect Lender’s interest in the Property and rights under this Security Instrument, including protecting and/or assessing the value of the
Property, and securing the Property. Lender’s actions can include, but are not limited to: (a) paying any sums secured by a lien which has priority over this Security Instrument; (b) appearing in court; and (c) paying Reasonable
Attorneys’ Fees to protect its interest in the Property and/or rights under this Security Instrument, including its secured position in a bankruptcy proceeding. Any amounts disbursed by Lender under this Section 2 shall become additional
debt of Borrower secured by this Security Instrument. These amounts shall bear interest at the Agreement rate from the date of disbursement and shall be payable, with such interest, upon notice from Lender to Borrower requesting payment. 

3. Assignment of Miscellaneous Proceeds; Forfeiture. All Miscellaneous Proceeds are hereby assigned to and shall be paid to Lender. Unless an
agreement is made in writing or Applicable Law requires interest to be paid on such Miscellaneous Proceeds, Lender shall not be required to pay Grantor any interest or earnings on such Miscellaneous Proceeds. In the event of a total or partial
taking, destruction, or loss in value of the Property, the Miscellaneous Proceeds shall be applied to the sums secured by this Security Instrument, whether or not then due, with the excess, if any, paid to Grantor. 

  
 3 

 If the Property is abandoned by Grantor, or if, after notice by Lender to Grantor that the
Opposing Party (as defined in the next sentence) offers to make an award to settle a claim for damages, Grantor fails to respond to Lender within 30 days after the date the notice is given, Lender is authorized to collect and apply the Miscellaneous
Proceeds either to restoration or repair of the Property or to the sums secured by this Security Instrument, whether or not then due. “Opposing Party” means the third party that owes Grantor Miscellaneous Proceeds or the party
against whom Grantor has a right of action in regard to Miscellaneous Proceeds. 
 Grantor shall be in default if any action or
proceeding, whether civil or criminal, is begun that, in Lender’s judgment, could result in forfeiture of the Property or other material impairment of Lender’s interest in the Property or rights under this Security Instrument. Grantor can
cure such a default by causing the action or proceeding to be dismissed with a ruling that, in Lender’s judgment, precludes forfeiture of the Property or other material impairment of Lender’s interest in the Property or rights under this
Security Instrument. The proceeds of any award or claim for damages that are attributable to the impairment of Lender’s interest in the Property are hereby assigned and shall be paid to Lender. 

4. Forbearance By Lender Not a Waiver. Any forbearance by Lender in exercising any right or remedy including, without limitation, Lender’s
acceptance of payments from third persons, entities or Successors in Interest of Grantor or in amounts less than the amount then due, shall not be a waiver of or preclude the exercise of any right or remedy. 

5. Loan Charges. Grantor shall pay all filing fees and mortgage recording fees and charges in connection herewith. Lender may charge Grantor fees
for services performed in connection with Grantor’s default, for the purpose of protecting Lender’s interest in the Property and rights under this Security Instrument, including, but not limited to, reasonable attorneys’ fees,
property inspection and valuation fees. In regard to any other fees, the absence of express authority in this Security Instrument to charge a specific fee to Grantor shall not be construed as a prohibition on the charging of such fee. Lender may not
charge fees that are expressly prohibited by this Security Instrument or by Applicable Law. If the Loan is subject to a law which sets maximum loan charges, and that law is finally interpreted so that the interest or other loan charges collected or
to be collected in connection with the Loan exceed the permitted limits, then: (a) any such loan charge shall be reduced by the amount necessary to reduce the charge to the permitted limit; and (b) any sums already collected from Grantor which
exceeded permitted limits will be refunded to Grantor. Lender may choose to make this refund by reducing the principal owed under the Agreement or by making a direct payment to Grantor. 
 6. Notices. All notices given by Grantor or Lender in connection with this Security Instrument must be in writing. Any notice to Grantor in connection with this Security Instrument shall be deemed
to have been given to Grantor when mailed by first class mail or when actually delivered to Grantor’s notice address if sent by other means. Notice to any one Grantor shall constitute notice to all Grantors unless Applicable Law expressly
requires otherwise. The notice address shall be the Property Address unless Grantor has designated a substitute notice address by notice to Lender. Grantor shall promptly notify Lender of Grantor’s change of address. There may be only one
designated notice address under this Security Instrument at any one time. Any notice in connection with this Security instrument shall not be deemed to have been given to Lender until actually received by Lender. If any notice required by this
Security Instrument is also required under Applicable Law, the Applicable Law requirement will satisfy the corresponding requirement under this Security Instrument. 

  
 4 

 7. Governing Law; Severability; Rules of Construction. This Security Instrument shall be governed by
federal law and the law of the jurisdiction in which the Property is located. All rights and obligations contained in this Security Instrument are subject to any requirements and limitations of Applicable Law. Applicable Law might explicitly or
implicitly allow the parties to agree by contract or it might be silent, but such silence shall not be construed as a prohibition against agreement by contract. In the event that any provision or clause of this Security Instrument or the Agreement
conflicts with Applicable Law, such conflict shall not affect other provisions of this Security Instrument or the Agreement which can be given effect without the conflicting provision. As used in this Security Instrument: (a) words of the masculine
gender shall mean and include corresponding neuter words or words of the feminine gender; (b) words in the singular shall mean and include the plural and vice versa; and (c) the word “may” gives sole discretion without any obligation to
take any action. 
 8. Grantor’s Right to Reinstate After Default. If Grantor meets certain conditions described below, Grantor
shall have the right to have enforcement of this Security Instrument discontinued at any time prior to the earliest of: (a) such period as Applicable Law might specify for the termination of Grantor’s right to reinstate; or (b) entry of a
judgment enforcing this Security Instrument. Those conditions are that Grantor: (a) cures all defaults hereunder and of any other covenants or agreements; (b) pays all expenses incurred in enforcing this Security Instrument, including, but
not limited to, Reasonable Attorneys’ Fees as defined herein, property inspection and valuation fees, and other fees incurred for the purpose of protecting Lender’s Interest in the Property and rights under this Security Instrument; and
(c) takes such action as Lender may reasonably require to assure that Lender’s Interest in the Property and rights under this Security Instrument, and Grantor’s obligation to pay the sums secured by this Security Instrument, shall
continue unchanged. Lender may require that Grantor pay such reinstatement sums and expenses in one or more of the following forms, as selected by Lender: (a) cash; (b) money order; (c) certified check, bank check, treasurer’s
check or cashier’s check, provided any such check is drawn upon an institution whose deposits are insured by a federal agency, instrumentality or entity; or (d) Electronic Funds Transfer. Upon reinstatement by Grantor, this Security
Instrument and obligations secured hereby shall remain fully effective as if no default had occurred. 
 9. Hazardous Substances. As used
in this Section 9, (a) “Hazardous Substances” are those substances defined as toxic or hazardous substances, pollutants, or wastes by Environmental Law and the following substances: gasoline, kerosene, other flammable or toxic
petroleum products, toxic pesticides and herbicides, volatile solvents, materials containing asbestos or formaldehyde, and radioactive materials; (b) “Environmental Law” means federal laws and laws of the jurisdiction where the
Property is located that relate to health, safety or environmental protection; (c) “Environmental Cleanup” includes any response action, remedial action, or removal action, as defined in Environmental Law and (d) an
“Environmental Condition” means a condition that can cause, contribute to, or otherwise trigger an Environmental Cleanup. Grantor shall not cause or permit the presence, use, disposal, storage, or release of any Hazardous
Substances, or threaten to release any Hazardous Substances, on or in the Property. Grantor shall not do, nor allow anyone else to do, anything 

  
 5 

 
affecting the Property (a) that is in violation of any Environmental Law, (b) which creates an Environmental Condition, or (c) which, due to the presence, use, or release of a
Hazardous Substance, creates a condition that adversely affects the value of the Property. The preceding two sentences shall not apply to the presence, use, or storage on the Property of small quantities of Hazardous Substances that are generally
recognized to be appropriate uses in the ordinary course of Grantor’s business and to maintenance of the Property (including, but not limited to, hazardous substances in consumer products). 

Grantor shall promptly give Lender written notice of (a) any investigation, claim, demand, lawsuit or other action by any
governmental or regulatory agency or private party involving the Property and any Hazardous Substance or Environmental Law of which Grantor has actual knowledge, (b) any Environmental Condition, including but not limited to, any spilling,
leaking, discharge, release or threat of release of any Hazardous Substance, and (c) any condition caused by the presence, use or release of a Hazardous Substance which adversely affects the value of the Property. If Grantor learns, or is
notified by any governmental or regulatory authority, or any private party, that any removal or other remediation of any Hazardous Substance affecting the Property is necessary, Grantor shall promptly take all required remedial actions in accordance
with Environmental Law. Nothing herein shall create any obligation on Lender for an Environmental Cleanup. 
 NON-UNIFORM COVENANTS.
Grantor and Lender further covenant and agree as follows: 
 10. Remedies. Lender shall give notice to Grantor upon Grantor’s
breach of any covenant or agreement in this Security Instrument. The notice shall specify: (a) the default; (b) the action required to cure the default; and (c) a date, not less than 30 days from the date the notice is given to Grantor, by which the
default must be cured. The notice shall further inform Grantor of the right to reinstate after default and the right to bring the non-existence of a default or any other defense of Grantor. As to any default by Borrower other than its failure to
deliver the Minimum Supply of Product to Lender under the Secured Obligation, Lender shall be entitled to the remedies provided for in the other paragraphs of this Mortgage. As to a default by Borrower in its obligation to deliver the Minimum Supply
of Product to Lender under the Secured Obligation, if such default is not cured on or before the date specified in the notice, Lender is hereby granted an easement and license to enter on and occupy that portion of the Land as is reasonably
required, for a period of time not to exceed twelve (12) months from the date of such default, for the sole purpose of removing the Secured Sand from the Land, in accordance with all laws and regulations and by use of a commercially reasonable
method. In such event, Lender shall also be entitled to entry of a money judgment against Borrower for collect its reasonable expenses in removing the Secured Sand from the Land and its all expenses incurred in pursuing the remedies provided in this
Section 10, including, but not limited to, Reasonable Attorneys’ Fees and costs of title evidence incurred therewith, if any. The remedy described in this paragraph shall be Lender’s sole and exclusive remedy under this Security
Instrument for Borrower’s default is its failure to deliver the Minimum Supply of Product to Lender under the Secured Obligation. In no event may Lender foreclose this Mortgage as provided in Chapter 846, Wis. Stats.. 

11. Release. Upon satisfaction of the Secured Obligation, Lender shall release this Security Instrument. Grantor shall pay any recordation costs.
Lender may charge Grantor a fee for releasing this Security Instrument, but only if the fee is paid to a third party for services rendered and the charging of the fee is permitted under Applicable Law. 

  
 6 

 12. Attorneys’ Fees. If this Security Instrument is subject to Chapter 428 of the Wisconsin
Statutes, “Reasonable Attorneys’ Fees” shall mean only those attorneys’ fees allowed by that Chapter.

2. Production and Supply of the Products 
  

	2.1	Commencement of Production/Minimum Supply.

Period”) consisting of *** tons of *** and *** tons of *** (the “Initial Minimum Supply”). 

  

	(b)	Beginning on May 1, 2012 through July 31, 2014 (the “Secondary Period”) Supplier is obligated to sell and Halliburton is obligated to buy, a minimum
annual volume of 600,000 tons of Product (the “Secondary Minimum Supply”) provided, however, such Secondary Miniumum Supply shall consist of no more than *** tons of ***. For any partial year, the Secondary Minimum Supply shall be prorated
based upon a full year’s supply. For the sake of clarity, for any partial year during the Secondary Period of this Agreement, the Secondary Minimum Supply shall be allocated monthly according to the following formula: six hundred thousand tons
divided by twelve (600,000 tons/12). Supplier shall be under no obligation to supply or sell Product in excess of the Initial Minimum Supply or the Secondary Minimum Supply. In the event that Supplier fails to supply to Halliburton either the
Initial Minimum Supply or the Secondary Minimum Supply during any Contract Year (a “Supply Shortfall”), Supplier shall have *** after the end of such Contract Year to, as the sole and exclusive remedy for such Supply Shortfall, either
(i) tender the Supply Shortfall, including by supplying Product from one or more third parties in accordance with Section 2.12, or (ii) pay to Halliburton within *** of the end of the Contract Year, as liquidated damages, an
amount equal to amount of the Supply Shortfall (expressed in tons) multiplied by $***. It will be Supplier’s sole discretion as to which option is utilized. 

 

	(c)	The “Monthly Maximum Supply Availability” during the Term is set forth in the table below. Supplier will not be obligated to fulfill orders that exceed the

 SPECIFIC TERMS IN THIS EXHIBIT HAVE BEEN REDACTED BECAUSE CONFIDENTIAL TREATMENT OF THOSE TERMS HAS BEEN
REQUESTED. THE REDACTED MATERIAL HAS BEEN SEPARATELY SUBMITTED TO THE SECURITIES AND EXCHANGE COMMISSION, AND THE TERMS HAVE BEEN MARKED AT THE APPROPRIATE PLACE WITH THREE ASTERISKS (***). 

 
  

	2.2	Supply Requirements; Price, Volume Discounts and Additional Volume. 

 

	(a)	During the Term of this Agreement, pricing will be fixed at $***/short ton for contracted volumes as well as any additional material that becomes available for purchase
by Halliburton. 

  

	(b)	Supplier agrees that Halliburton shall be considered a preferred purchaser and, accordingly, prices paid by Halliburton during the Term of this Agreement shall be no
greater than the lowest prices charged by Supplier for the same Product to any future purchasers in the oilfield services industry during any period covered by this Agreement. Notwithstanding the foregoing, this Section shall not apply to:
(a) contracts paid in advance; or (b) contracts in place between Supplier and other customers before the Effective Date of this Agreement; or (c) to any spot sales made by Supplier; or (d) for sales of any Product offered to but
not taken by Halliburton; or (e) sales of Product from facilities owned by Supplier at locations other than 9000 State Highway 173, Tomah, Wisconsin 54660. 

 

	(c)	Subject to the availability of excess Product as determined by Supplier, Supplier may make available to Halliburton any additional volume, “Additional Volume”
over the Monthly Maximum Supply Availability, on a right of first refusal basis. Supplier will provide its estimate of Additional Volume for delivery up to two months in advance of the actual availability and will use its best efforts to work with
Halliburton regarding scheduling and delivery of such Additional Volumes. 

  

	2.3	Halliburton Minimum Purchase Requirement. During the Term, Halliburton shall be required to take and, in accordance with Section 3.1, pay for
a minimum aggregate of 300,000 tons of Product during the Initial Period and 600,000 tons of Product per Contract Year for the Secondary Period (the “Minimum Purchase Requirement”); provided, however, that if, due solely to Force Majeure
or the unavailability of rail cars in the market, Halliburton is unable to take delivery of Products as contemplated hereunder for a period of time during a Contract Year, Halliburton shall not be deemed to be in breach of this Agreement as a result
of such failure so long as Halliburton is using best efforts to obtain rail cars and minimize the period of time during which Halliburton is unable to take delivery of Products; provided, further, however, that nothing in this sentence shall be
construed to relieve Halliburton of its obligations to make payments under this Agreement (including the obligation to make any Makewhole Payments as contemplated in Section 2.6). 

 

	2.4	During the Initial Period, the Minimum Purchase Requirement shall be ordered by Halliburton in installments of not less than 25,000 tons of Product per calendar month
(the “Initial Monthly Minimum Requirement”), and not more than the Monthly Maximum Supply Availability, beginning in September of 2011 and continuing thereafter for each calendar month during the Initial Period. In the event that
Halliburton fails to purchase one ninth (1/9) of the Minimum Purchase Requirement of Product from Supplier during any particular calendar month in the Initial Period in which Supplier was ready, willing and able to deliver 33,333 tons of
Product, then the “Purchase Shortfall” shall be the amount by which one ninth (1/9) of the Minimum Purchase Requirement exceeds the amount of Product actually purchased by Halliburton during such calendar month.

  

	2.5	 During the Secondary Period, the Minimum Purchase Requirement shall be ordered by Halliburton in installments of not less than 40,000 tons of Product
per calendar month (the “Secondary Monthly Minimum Requirement”), and not more than the Monthly Maximum Supply Availability, beginning in May of 2012 and continuing thereafter for each calendar

month during the remaining Term of this Agreement. In the event that Halliburton fails to purchase one twelfth (1/12) of the Minimum Purchase Requirement of Product from Supplier during any
particular calendar month in the Secondary Period in which Supplier was ready, willing and able to deliver 50,000 tons of Product, then the “Purchase Shortfall” shall be the amount by which one twelfth (1/12) of the Minimum Purchase
Requirement exceeds the amount of Product actually purchased by Halliburton during such calendar month until the minimum annual volume is met. 

  

	2.6	On written notice of such Purchase Shortfall to Halliburton by Supplier, Halliburton shall have *** after the month of the Purchase Shortfall to purchase tonnage of
Product in excess of the Initial or Secondary Monthly Minimum Requirement as applicable (but subject to the Monthly Maximum Supply Availability) to make up for the Purchase Shortfall. If Halliburton fails to purchase the full amount of the Purchase
Shortfall in such *** period, Halliburton shall be obligated to pay to Supplier an amount equal to the amount of the Purchase Shortfall not purchased by Halliburton in such *** period (expressed in tons) multiplied by $*** (the “Makewhole
Payment”). The Makewhole Payment shall be paid within *** of written demand by Supplier, by wire transfer of immediately available funds to the account designated in writing by Supplier. The aggregate Purchase Shortfall amount for a Contract
Year shall not exceed the Initial or Secondary Minimum Purchase Requirement for such Contract Year, as applicable, less the amount of Product ordered and delivered to Halliburton. Halliburton reserves the right to resell goods purchased from
Supplier if deemed necessary by Halliburton in order to satisfy the Initial or Secondary Minimum Purchase Requirement. Supplier shall not be obligated to deliver more than the Monthly Maximum Supply Availability on any given calendar month.

  

	2.7	Halliburton may elect to sell all or any amount of Product comprising the Minimum Purchase Requirement in order to meet its obligations under this Agreement. If
requested by Halliburton, Supplier will use its best efforts to assist Halliburton with delivery schedules and delivery locations for any Product sold by Halliburton. Sales of such Product by Halliburton will count towards fulfilling
Halliburton’s Minimum Purchase Requirement. Nothing in this Section will release Halliburton from its payment obligations to Supplier for such Product sold by Halliburton. 

 

	2.8	Forecast of Demand. Halliburton shall provide, on a quarterly basis, a non-binding 3-month rolling volume forecast of its anticipated purchase of
Products (“Forecast Amount”). Updates to the Forecast Amount indicated in the six-month rolling volume forecast will be made and communicated periodically outside of the three-month rolling volume forecast as promptly as practicable after
Halliburton becomes aware of such changes. Supplier shall notify Halliburton within ten (10) Business Days of receiving a forecast or update if Supplier anticipates being unable to meet the anticipated purchase amounts. Supplier shall not be
obligated to deliver more than the Monthly Maximum Supply Availability on any given calendar month. 

  

	2.9	 Title and Risk Of Loss. Title and risk of loss or damage to Products shall pass to Halliburton as defined by Incoterm, FCA
(details listed in table below), Incoterms 2010. Supplier is not responsible for unfilled orders resulting from any shortage or lack of availability of rail cars for shipment of orders except that Supplier must always meet the Minimum Supply volumes
as specified in Section 2.1. Supplier warrants clear title to the

Products at the time title to the Products passes to Halliburton, free from any and all liens or other encumbrances. Supplier is responsible for properly loading and correct stowing of the
Product on the Halliburton nominated carrier, at its expense, and will comply with any documentary instructions of Halliburton in the shipment process.

	2.10	Orders. During the Term, Supplier shall supply to Halliburton, and Halliburton shall purchase, the types and amounts of the Products ordered by
Halliburton from time to time under this Agreement; provided that Supplier shall be under no obligation to supply or sell, and Halliburton shall not have the right to buy Products in excess of the Minimum Purchase Requirement or the Monthly Maximum
Supply Availability. This Agreement shall control and govern all transactions between the Parties with respect to the sales and purchases of Products, whether under subsequent verbal and/or written Work Orders, unless subject to an express, duly
executed agreement (which is not a pre-printed form, terms contained on an Internet site or order confirmation) for the particular subject matter. The terms of this Agreement shall prevail over the terms in the Work Order in the event of a conflict
unless specific reference and identification is made to the provision of this Agreement to be modified and the intention to modify is explicitly stated and signed by both Parties. Such changes shall be effective for that Work Order only. Printed
terms and conditions contained in documents issued to Halliburton by Supplier or from Halliburton to Supplier with respect to the Products shall be of no force and effect and shall be superseded by the terms and conditions which are contained in
this Agreement. No waiver by either Party of any of the terms, provisions or conditions hereof shall be effective unless said waiver shall be in writing and signed by an authorized officer of such Party and specifically referencing this Agreement.
Supplier agrees to promptly process all of Halliburton’s orders under the terms of this Agreement. 

  

	2.11	Delivery. Supplier agrees that all Products ordered by Halliburton will be delivered to Halliburton per this Article 2 and in accordance
with a reasonable delivery date contained in the Work Order, subject to the Monthly Maximum Supply Availability. 

  

	2.12	Alternate Sources of Supply. Supplier may, in its discretion, source Product from third Persons for purposes of selling such Product to Halliburton
hereunder, so long as such Product meets or exceed the Specifications and Quality Standards subject to Section 5.1 and Supplier is otherwise in compliance with the other provisions of this Agreement.

end of such calendar month. Each invoice shall be for the tonnage actually shipped. Payment shall be due no later than the *** after the date of receipt of the invoice. 

 

	(b)	Should Halliburton fail to make an adjustment to an invoice to which it was entitled, and as a result has overpaid amounts due to Supplier, then upon such overpayment
becoming known and agreed to by the Parties, Supplier shall issue a credit to Halliburton within ***, which credit may be applied by and utilized by Halliburton against future invoices owing to Supplier and, to the extent any credit has not been

	(c)	Interest Rate on Past Due Payments. Payments *** or more past due shall bear interest at the rate of *** from (and including) the date on which the

 4. Taxes. Seller is responsible for all
taxes legally imposed upon its business, including but not limited to taxes imposed upon its income, its personnel or its property. Such taxes are on Sellers account. Halliburton shall pay and Seller shall collect and is responsible for the
reporting of applicable transaction taxes such as severance, sales, use, value added, manufacture, excise, or similar taxes, unless a valid exemption is claimed by Halliburton. Transaction taxes are in addition to established prices and shall be

 SPECIFIC TERMS IN THIS EXHIBIT HAVE BEEN REDACTED BECAUSE CONFIDENTIAL TREATMENT OF THOSE TERMS HAS BEEN
REQUESTED. THE REDACTED MATERIAL HAS BEEN SEPARATELY SUBMITTED TO THE SECURITIES AND EXCHANGE COMMISSION, AND THE TERMS HAVE BEEN MARKED AT THE APPROPRIATE PLACE WITH THREE ASTERISKS (***). 

 
  

	5.2	Inspection. Supplier shall permit representatives of Halliburton, at any reasonable time and upon reasonable prior notice, to inspect the Products
manufactured by Supplier at Supplier’s Facility prior to the time of delivery of Products to the carrier. Whether or not Halliburton conducts an inspection, Supplier shall provide Halliburton a production sample per Work Order in order to show
compliance with Section 5.1. A “Production Sample” is defined as one hundred (100) grams of the actual production run and/or lot number of the delivered Product. Such Production Sample shall be retained by Supplier and
provided to Halliburton up to one hundred twenty (120) days from the date of the Work Order. Supplier shall provide multiple-sieve analysis of Product at Supplier’s facility for inspection/confirmation by Halliburton.

  

	5.3	Rejection. Halliburton shall be entitled to reject any of the Products that do not comply with Section 5.1; provided that any Products not
rejected prior to the time of delivery of such Products to the carrier shall be deemed accepted by Halliburton, unless testing of the applicable Production Sample by an independent third party laboratory conclusively determines that Products
previously accepted by Halliburton do not comply with Section 5.1 (in which case Halliburton may reject such previously accepted Products upon such determination by the independent third party laboratory). In the event that Halliburton
timely rejects any Products, Supplier shall replace such Products at its sole cost. Supplier shall provide such replacement Products at Supplier’s Facility within a reasonable time under the circumstances. The time for fulfillment of the
Minimum Purchase Requirement shall be extended by the amount of time Supplier takes to replace the non-conforming Product with conforming Product.

PRODUCTS ARE FIT FOR A PARTICULAR PURPOSE, NOTWITHSTANDING ANY COURSE OF DEALING OR INDUSTRY PRACTICE INCONSISTENT WITH THIS AGREEMENT. Should Halliburton choose to provide a warranty to its customers beyond the warranty provided by Supplier,
then Halliburton shall bear the entire cost of such warranty. Should any Product not comply with the warranties of Supplier expressly made in this Agreement, then Supplier shall, as the sole and exclusive remedy of Halliburton, provide replacement
Product to Halliburton at Supplier’s Facility. 

  

	5.5	Insurance Requirements. Each of Supplier and Halliburton shall maintain and exhibit to the other on demand, (a) certificates of comprehensive general
liability insurance and employers liability insurance for such amount as may from time to time be agreed between the Parties but in any event not be less than *** in each case and (b) certificates of excess liability insurance for such amount

 pg. 10

	 	
confidentiality of such information and (b) to prospective purchasers, investors or lenders (subject to the execution by the prospective purchasers, investors or lenders of written
confidentiality agreements with terms at least as stringent as those contained herein ); provided, that in no event shall such information be disclosed to a competitor of such other Party unless such competitor is seeking to purchase, invest or lend
funds to Supplier. If a receiving Party receives a request to disclose all or any part of the disclosing Party’s Confidential Information under the terms of a valid and effective subpoena, decree or order issued by a court of competent
jurisdiction or by a governmental body, the receiving Party hereby agrees to, and agrees to cause its Affiliates to, immediately notify the disclosing Party in writing of the existence, terms and circumstances surrounding the request, so that the
disclosing Party may seek an appropriate protective order or waive the receiving Party’s compliance with the provisions of this Agreement (and, if the disclosing Party seeks an order, to provide the cooperation as said owner shall reasonably
request); and if disclosure of Confidential Information is required in the written opinion of a receiving Party’s counsel, the receiving Party shall exercise reasonable efforts, with the cooperation of the disclosing Party, to obtain an order
or other reliable assurance that confidential treatment will be accorded to the disclosed Confidential Information.

of use other than for the purposes expressly stated in this Agreement, whether directly or indirectly, any Intellectual Property of the other Party. 

  

	6.7	Remedies. The Parties hereby agree that the breach of this Article 6 would cause irreparable harm, for which money damages would not be
adequate compensation. If any Party breaches or threatens a breach of the provisions of this Article 6, the other Party shall be entitled to an injunction upon proper proof required by law in any court of competent jurisdiction restraining
the breaching Party from violating the provisions without the necessity of posting a bond therefor. Nothing herein shall be construed as prohibiting the other Party from pursuing any other remedies available to it at law or in equity for enforcement
of this Article 6. 

  

	6.8	Intellectual Property Indemnification. 

  

	(a)	 The following terms apply to any claim of infringement of any United States patent, by a third party arising out of or relating to a Product furnished

 pg. 11

	 	
Product furnished by Supplier. Subject to Section 6.8(b), Supplier shall defend or settle, at its own expense, any action or suit against Halliburton with respect to an Infringement
Claim for which it is responsible. Halliburton shall promptly notify Supplier of any Infringement Claim and shall reasonably cooperate with Supplier at Supplier’s expense to facilitate the defense of each claim. 

 

	(b)	Supplier’s obligations under Section 6.8(a) shall not apply to the extent that an Infringement Claim relates to, arises or results from, or is due to
(i) Halliburton’s modification of a Product or use of a Product in combination with any other device and the Infringement Claim would not have arisen in the absence of that modification or combination; (ii) Supplier’s compliance
with designs or specifications of Halliburton; or (iii) Halliburton’s continued use of the allegedly infringing Product after being notified by the Supplier to cease such use. In the event of an act or omission by Halliburton described in
this Section 6.8(b), Halliburton shall indemnify and hold Supplier harmless from any Damage resulting from such act or omission.

writing as the Parties may request.

this Agreement. Each Party also agrees that it will be responsible for any breaches by its Affiliates of the terms of this Article 6.

in question. Neither Party shall be deemed to be in breach of this Agreement, or otherwise be liable to the other, for any delay in performance or the non-performance of any of its obligations under this Agreement, to the extent that the delay or
non-performance is due to any Force Majeure, and the time for performance of that obligation shall be extended accordingly; provided, that if the Force Majeure in question prevails for a continuous period in excess of thirty (30) days, the

 SPECIFIC TERMS IN THIS EXHIBIT HAVE BEEN REDACTED BECAUSE CONFIDENTIAL TREATMENT OF THOSE TERMS HAS BEEN
REQUESTED. THE REDACTED MATERIAL HAS BEEN SEPARATELY SUBMITTED TO THE SECURITIES AND EXCHANGE COMMISSION, AND THE TERMS HAVE BEEN MARKED AT THE APPROPRIATE PLACE WITH THREE ASTERISKS (***).

immediately terminated for breach if Supplier fails to produce and deliver Products that meet the Specifications for a period of more than ***. Upon such breach, Halliburton may terminate this Agreement immediately by giving written notice of
termination to Supplier. Subject to fulfilling its obligations to purchase the Minimum Purchase Requirement, Halliburton may terminate any Work Order upon *** written notice. In the event Supplier has incurred costs in executing the Work Order up to
termination, Halliburton shall reimburse Supplier for such documented costs. In the event of Supplier’s failure to perform any of its material obligations under this Agreement (including failure to deliver agreed upon amounts of sand and not
making up the Supply Shortfall as contemplated by Section 2.1(b),), Halliburton shall promptly give Supplier notice thereof. Such notice shall specifiy the nature of such failure with particularity and in reasonable detail, including the
specific provision of this Agreement to which such purported failure relates. Suplier shall use commercially reasonable effort to cure or otherwise remedy the failure specified in such notice within *** after its receipt of such notice. A failure
specified in such notice which Supplier does not cure or otherwise remedy in such *** period shall be deemed a “Supplier Uncured Failure”. Halliburton shall have the right to terminate this Agreement if Supplier has more than ***.
Halliburton’s sole and exclusive damages in case of such termination shall be limited to $*** per short ton of Product that remains undelivered under the Minimum Purchase Requirements for the remaining life of the Contract after the filling of
all outstanding Work Orders. The Parties acknowledge and agree that in the event of a breach under this Section 8.2, the damages would be difficult if not impossible to quantify, and accordingly, such payment shall be for liquidated
damages and not as any form of penalty. 

  

	8.3	Termination by Supplier. If Supplier is not then in breach of this Agreement giving rise to an event of termination, Supplier shall be entitled to
terminate this Agreement should Halliburton fail to order and take delivery of Product or pay sums due hereunder. Supplier shall give Halliburton written notice of any such failure and provide a reasonable time to cure which shall not exceed ***.
Should Halliburton fail to cure prior to the end of such *** period, then Supplier may terminate this Agreement immediately. Supplier’s sole and exclusive damages in case of such termination shall be limited to $*** per short ton of Product
that remains undelivered under the Minimum Purchase Requirements for the remaining life of the Contract after the filling of all outstanding Work Orders. The Parties acknowledge and agree that in the event of a breach under this
Section 8.3, the damages would be difficult if not impossible to quantify, and accordingly, such payment shall be for liquidated damages and not as any form of penalty. 

 

	8.4	Termination of Work Order. A termination of a Work Order does not terminate this Agreement. A termination of this Agreement does not terminate any
existing Work Order until such Work Order is completed, unless such Work Order is expressly terminated also. 

  

	8.5	Events Upon Termination. 

  

	(a)	Upon expiration of this Agreement or the termination of the Agreement for reasons other than pursuant to Section 8.2, Halliburton shall purchase from
Supplier all Products which have been ordered from Supplier but not delivered to Halliburton at the date of termination, and Supplier shall promptly manufacture and deliver such Products to Halliburton. 

  
 pg. 13

	(b)	Upon expiration of this Agreement or the termination of this Agreement for any reason, Supplier shall forthwith cease to use, either directly or indirectly, any of the

Intellectual Property and forthwith return to Supplier all Supplier Intellectual Property and Supplier Confidential Information except to the extent necessary to use the Products theretofore supplied by Supplier hereunder. In such case Supplier
hereby grants Halliburton or its designee an irrevocable, royalty free license to use such Supplier Intellectual Property and Supplier Confidential Information to the extent it is incorporated into such Product(s) theretofore supplied by Supplier
hereunder. 

  

	(c)	Upon expiration of this Agreement or the termination of this Agreement for any reason, all obligations of the Parties hereunder shall terminate, except for any
obligations that are expressly stated to survive the expiration of the Term or termination of this Agreement and any obligations that remain executory which obligations, to the extent they remain executory, shall remain in full force and effect
until fully performed by the obligated Party as stated in this Agreement. The respective Parties’ obligations under Section 3.1, Section 5.4, Article 6, this Section 8.5 and Articles 9 through
14 shall survive the expiration of the Term or termination of this Agreement. Neither expiration nor termination of this Agreement shall relieve any Party of liability for breaches of this Agreement prior to such expiration or termination.

 9. INDEMNITY AND LIMITATION OF LIABILITY 

 

	9.1	INDEMNIFICATION.

  

	(a)	HALLIBURTON AND SUPPLIER AGREE TO FULLY RELEASE, INDEMNIFY, DEFEND AND HOLD ONE ANOTHER AND THEIR RESPECTIVE PARENT, SUBSIDIARY OR AFFILIATED ENTITIES HARMLESS FROM
AND AGAINST ANY AND ALL CLAIMS, COSTS, CAUSES OF ACTION, FINES, PENALTIES OR OTHER LIABILITY THAT MAY BE ASSERTED AGAINST THE OTHER AND/OR THEIR RESPECTIVE GROUPS, TO THE EXTENT, ARISING OUT OF THE INDEMNIFYING PARTY’S OR THEIR RESPECTIVE
GROUP’S NEGLIGENCE OR WILLFUL MISCONDUCT IN CONNECTION WITH PERFORMANCE UNDER THIS AGREEMENT.

  

	(b)	NOTWITHSTANDING PARAGRAPH 9.1, HALLIBURTON AND SUPPLIER SPECIFICALLY ACKNOWLEDGE AND AGREE THAT THE GOODS PROVIDED BY SUPPLIER HEREUNDER ARE INHERENTLY DANGEROUS AND
HALLIBURTON AGREES TO INDEMNIFY AND HOLD HARMLESS SUPPLIER ITS PARENT, SUBSIDIARY AND AFFILIATED ENTITIES FROM AND AGAINST ANY CLAIMS, COSTS, CAUSES OF ACTION, FINES, PENALTIES OR OTHER LIABILITY TO THE EXTENT CAUSED BY HALLIBURTON’S NEGLIGENT
USE OF THE PRODUCT(S) OR NEGLIGENT OR WILLFUL FAILURE TO PROVIDE ADEQUATE WARNING OR REASONABLE PROTECTIVE PROCEDURES AND EQUIPMENT WITH RESPECT TO THE USE OF THE PRODUCT(S) 

  
 pg. 14

	9.2	Limitation of Liability. NEITHER PARTY SHALL BE LIABLE TO THE OTHER PARTY FOR, AND EACH PARTY RELEASES THE OTHER FROM LIABILITY ATTRIBUTABLE TO, ANY SPECIAL,
ECONOMIC, INDIRECT, CONSEQUENTIAL, OR OTHER INCIDENTAL DAMAGES ARISING OUT OF THE PERFORMANCE OF THIS AGREEMENT, OR DEFAULT IN THE PERFORMANCE HEREOF, WHETHER BASED UPON CONTRACT, TORT (INCLUDING NEGLIGENCE, PRODUCT LIABILITY OR STRICT LIABILITY),
OR WARRANTY. 

  

	9.3	Indemnification Procedure. In the event either Party learns of any claim, liability, demand or cause of action relating to this Agreement or the
performance hereunder, which said Party shall determine, in its sole discretion, that the other Party may be liable therefor, said Party shall promptly notify the other Party. If indemnity is required by any of the terms of this Agreement, the
indemnifying Party shall have the right to control all litigation and shall defend the other and pay all settlements, judgments, costs, and expenses (including without limitation court costs and reasonable attorneys’ fees), whether related or
unrelated, similar or dissimilar to the foregoing, incident thereto. Each Party, if requested, agrees to cooperate with the other in any defense, and the indemnifying Party shall reimburse the other for all reasonable expenses incurred in connection
therewith. The indemnified Party shall have the right to have counsel of its own choosing and at its sole expense participate in any such litigation. Notwithstanding the foregoing, however, neither Party shall effect settlement of or compromise any
such claim or proceedings without having obtained the prior written consent of the other Party, which consent shall not be unreasonably withheld, conditioned or delayed; provided that the indemnifying Party may settle or compromise any such claim if
the settlement or compromise (a) requires solely the payment of money damages by the indemnifying Party, and (b) includes as an unconditional term thereof the release by the claimant or the plaintiff of the indemnified Party from all
liability in respect of such claim. If the indemnified Party does not consent to a settlement which the indemnifying Party is willing to accept, then the indemnifying Party’s liability shall be limited to the amount for which the claim could
have been settled provided, such settlement does not require the indemnified Party to forego any property rights other than the amount of payment of the proposed settlement. 

 

	9.4	Compliance with Law. Subject to the limitations of this Agreement, it is agreed that in the performance of this Agreement all matters shall be conducted
in full compliance with any and all applicable federal, state, provincial and local laws, rules and regulations in the area(s) in which the matters are being conducted. Any performance obligation arising under this Agreement is contingent on the
prior receipt of all necessary government authorizations. If either Party is required to pay any fine or penalty or is subject to a claim from the other Party’s failure to comply with applicable laws, rules or regulations, the Party failing to
comply shall defend, indemnify and hold harmless the other Party for all damages, fees and/or fines for such failure to comply to the extent of the indemnifying Party’s allocable share of the failure to comply. 

 

	9.5	 Antibribery. Supplier represents and warrants that it and all of its Affiliates and agents shall act in accordance with the principles
described in the Convention on Combating Bribery of Foreign Public Officials in International Business Transactions, signed in Paris on December 17, 1997 (“the Convention”), and the Convention’s Commentaries (collectively the
“OECD Principles”), and shall comply with all applicable laws implementing the OECD Principles (including the U.S. Foreign Corrupt Practices Act of 1977), as well as any applicable local laws related to anti-corruption, anti-kickbacks, and
anti-money laundering. Supplier agrees not to take or fail to take any action that might 

  
 pg. 15

	 	
cause Halliburton to be in violation of any such laws. In addition to the foregoing, Supplier represents and warrants that it and its Affiliates have not and shall not request, induce, make,
offer, authorize, promise to make any payment or transfer anything of value, directly or indirectly, (a) to any governmental official or employee (including employees of government-owned or government-controlled corporations, agencies or
bodies), (b) any official or employee of a public international organization, (c) to any political party, official of a political party or candidate, or (d) to any third party knowing, believing, or suspecting that such third party
will give the payment, or any portion thereof, to any of the foregoing persons in order to obtain or retain business, or for any other improper purpose. Any payments to governmental officials or employees on behalf of Halliburton must be promptly
reported to Halliburton. 

  

	9.6	Code of Conduct/ Gifts, Entertainment and Travel. It is considered to be in conflict with Halliburton’s interest for its employees or any member of
their immediate family to accept gifts, payments, extravagant entertainment, services, or loans in any form from anyone soliciting business, or who may already have established business relations with Halliburton. Gifts of nominal value and
entertainment, meals, and social invitations that are customary and proper under the circumstances and that do not place the recipient under any obligation are acceptable. Any gifts, payment of individual expenses, including, without limitation,
trips, or conveyances to Halliburton employees shall be disclosed in writing to the Halliburton Ethics and Compliance Group. 

  

	9.7	Information Requests. Supplier shall maintain full and complete accounting records of activity performed and expenditures incurred by Supplier in
connection with this Agreement in such a manner and detail as to permit verification of compliance with the performance obligations, including, by way of illustration and not limitation, pricing requirements, as well as the provisions of Sections
9.4 through 9.6 of this agreement. Halliburton shall have the right to audit such Supplier’s records for a period of two (2) Years from the expiration or termination of this Agreement. This provision shall survive expiration or
termination of this Agreement. 

 Notwithstanding anything to the contrary, neither Party shall be required to
take or refrain from taking any action prohibited or penalized under the laws of the United States, including the U.S. antiboycott laws. 
  

	9.8	Economic Sanctions and Export Controls. Supplier agrees to fully comply with all economic sanctions and export control laws and regulations, including
those regulations maintained by the U.S. Commerce Department’s Bureau of Industry and Security and the U.S. Treasury Department’s Office of Foreign Assets Control. In addition, Supplier shall not, directly or indirectly, sell, provide,
export, re-export, transfer, divert, loan, lease, consign or otherwise dispose of any Halliburton equipment, product, services, software, source code, technical data or technology to or via any person, entity or destination, or for any activity or
end-use restricted by the laws or regulations of the United States or any other applicable jurisdiction (including nuclear, missile, chemical or biological weapons proliferation, military, or money laundering activities) without first obtaining all
required government authorizations. 

 10. Nature of Agreement 

 

	10.1	 Assignment. Either Party shall have the right to assign or transfer to any Person any of its rights or obligations under this Agreement
without the prior written consent of the other Party, provided that the assigning Party shall remain liable to the other 

  
 pg. 16

	 	
Party under the terms of this Agreement notwithstanding such assignment. This Agreement shall be binding on and inure to the benefit of the Parties and their respective successors and permitted
assigns, including any successor upon a sale or change of control of a Party. This Agreement is intended solely for the benefit of the Parties and their respective successors and permitted assigns. 

 

	10.2	Relationship. Each of the Parties is an independent contractor with respect to the other and is not an employee of the other Party or any of the other
Party’s Affiliates, and nothing in this Agreement is intended to constitute a partnership or a master and servant relationship between the Parties. Each of the Parties understands and agrees that this Agreement does not create an exclusive
dealings arrangement and that each of Halliburton and Supplier may enter into similar arrangements with other companies with respect to similar or the same products. Nothing in this Agreement shall be construed to create any duty to, or standard of
care with reference to, or liability of a Party to, any person not a Party to this Agreement. Nothing in this Agreement shall be deemed to constitute any fiduciary or special relationship or duty between the Parties and each Party may take actions
hereunder that are for its own self-interest without any duty or, subject to the express terms of this Agreement, liability to the other Parties. 

  

	10.3	Entire Agreement; Amendment. This Agreement, including its appendices, exhibits and schedules, constitutes the entire Agreement between the Parties with
respect to the subject matter hereof and supersedes any existing agreements between them whether oral or written. The terms of this Agreement shall only be amended, modified or supplemented as set forth herein or in a writing signed by or on behalf
of both or the Parties. In case of a conflict between this Agreement and a purchase order (Work Order) or purchase order confirmation contemplated hereunder, the terms of this Agreement shall govern. Acceptance of a Work Order or purchase order
confirmation is insufficient to amend this Agreement unless a separate writing is duly executed by all the Parties specifically amending this Agreement. 

  

	10.4	Reformation. If any term or other provision of this Agreement is invalid, illegal or incapable of being enforced by any rule of law or public policy, all
other conditions and provisions of this Agreement shall nevertheless remain in full force and effect so long as the economic and legal substance of the transactions contemplated hereby are not affected in any manner materially adverse to any Party.
Upon the determination that any term or other provision is invalid, illegal or incapable of being enforced, the Parties shall negotiate in good faith to modify this Agreement so as to effect the original intent of the Parties as closely as possible
in an acceptable manner to the end that transactions contemplated hereby are fulfilled to the extent possible. In the event any such provision, clause, sentence or part of this Agreement cannot be modified to comply with the law, then said
provision, clause, sentence or portion of the Agreement shall be deemed to be deleted from the Agreement and the remaining terms and conditions shall remain in full force and effect. 

11. Notices and Service 
  

	11.1	 Addresses. All notices, requests, consents, directions and other instruments and communications required or permitted to be given
