 AMENDED AND RESTATED MASTER PRODUCT PURCHASE AGREEMENT 

This Amended and Restated Master Product Purchase Agreement (this “Agreement”) is made and entered into as of this 16th day
of December, 2015 (the “Execution Date”) by and between Smart Sand, Inc. a Delaware Corporation, with a place of business at 1010 Stony Hill Rd, Ste 175, Yardley, PA 19067 (“Smart Sand”) and Archer Pressure Pumping,
LLC, a Delaware limited liability company, with a place of business at 10613 W. Sam Houston Pkwy N., Suite 600, Houston Texas 77064 (“Buyer”). 

RECITALS 
 A.
Whereas, Smart Sand mines, processes and sells certain industrial sand products; and 
 B. Whereas, Smart Sand and Buyer are parties to that
certain Master Product Purchase Agreement, dated as of August 19, 2014 (the “Original Agreement”); and 
 d. Whereas,
Smart Sand and Buyer desire to amend and restate in its entirety the Original Agreement, as set forth in this Agreement, to provide for the terms under which Smart Sand will sell such products to Buyer, based on firm monthly and yearly commitments
as more particularly described herein. 
 AGREEMENT 

Now therefore, in consideration of the mutual covenants herein, the parties hereto agree as follows: 

1. Products, Forecasts and Quantity Commitments  

1.1 Subject to the terms and conditions of this Agreement, during the Term (as defined in Section 7.1), Smart Sand agrees to sell and
deliver to Buyer, and Buyer agrees to purchase and accept from Smart Sand, frac sand products based on the specifications (the “Specifications”) set forth in Appendix A attached hereto and incorporated by reference (each a
“Product” and collectively, the “Products”), and based on the product mix and monthly minimum volumes specified in Appendix B, subject to the minimum yearly tonnage amounts as follows: 

 

					
	 Contract
 Year
	  	 Minimum

Tons per Year
	 	Minimum Tons
per Quarter
	 ***
	  	***	 	***

 Nothing in this Agreement shall be construed as limiting either party’s right to enter into a Product
purchase agreement with a third party at any time. 
 1.2 For purposes of this Agreement: (i) the “Interim Period”
shall mean the period beginning on *** and ending at 11:59 p.m. on ***; and (ii) a “Contract Year” shall mean (i) the period beginning *** of a given year and ending at 11:59 p.m. on *** of the immediately following year.
For the avoidance of doubt, ***. 
 Buyer shall provide Smart Sand with an initial *** non-binding forecast for all Product requirements prior to the first
month of delivery in Contract Year 1 hereunder for each quarter. On a monthly basis, after issuance of the initial *** forecast as specified above, and on or before the first day of each ensuing calendar month, Buyer shall update its forecast to
maintain a *** rolling forecast (each such forecast, a “Forecast”). All quantities stated for the first *** period of any Forecast shall be firm commitments of Buyer to purchase the stated 

 EXECUTION COPY 
  

 
quantity of each Product (each, a “Commitment”). Any estimate for periods between *** provided by Buyer shall be a non-binding good faith forecast of delivery requirements. If
Buyer does not provide an updated Forecast in any given month, the Forecast for such month, including the *** Commitment, shall be the greater of the previous month’s volume or the Minimum Tons per Month. 

1.3 During the Interim Period, subject to availability as determined by Smart Sand in its sole discretion, Buyer may purchase Products from
Smart Sand at a Base Price of *** per ton (plus applicable surcharges). The aggregate of the Minimum Tons per Year in *** shall be reduced in the aggregate by an amount equal to *** of the total tons of Products purchased (and paid for in full per
the terms of this Agreement) by Buyer during the Interim Period. Such reduction shall be split ***, and shall be proportionally applied to each quarter therein. By way of example, if Buyer purchases an aggregate of *** tons of Products during the
Interim Period, the Minimum Tons per Year in each of *** shall be reduced by *** tons, and the Minimum Tons per Quarter in each Contract Year shall be reduced by *** tons. 

1.4 Commencing in Contract Year 1, Smart Sand shall guarantee Products equal to the minimum monthly volumes set forth on Appendix B
attached hereto. In no event will Smart Sand be required to provide to Buyer in any given month during the Term an aggregate quantity of Products exceeding *** percent of the Minimum Tons per Year for the applicable Contract Year. 

1.5 In the event that Buyer purchases less than the Minimum Tons per Quarter stated in Section 1.1 above during any quarter in any
Contract Year during the Term, Buyer shall pay to Smart Sand on or before the date that is *** following the end of such quarter an amount (the “Quarterly Shortfall Payment”) equal to (i) a price calculated by *** (the
“Quarterly Shortfall Price”), multiplied by (ii) the difference between (a) the applicable Minimum Tons per Quarter stated above and (b) the total of the actual tons of Product purchased by the
Buyer during such quarter (“Quarterly Purchased Tons”) plus tons of all Replacement Products (as defined in Section 4.2) purchased during such quarter (the resulting amount, the “Quarterly Net Tons”) (i.e.
(i) Quarterly Net Tons = Minimum Tons per Quarter – (Quarterly Purchased Tons + Replacement Products), and (ii) Quarterly Shortfall Payment = Quarterly Net Tons * Quarterly Shortfall Price). Any Quarterly Shortfall Payment for the
fourth quarter of *** shall be payable notwithstanding the expiration of this Agreement. If the Quarterly Net Tons is equal to or less than 0, then the Quarterly Shortfall Payment shall be $0. 

1.6 Buyer shall issue purchase orders to Smart Sand setting forth the quantities of Products, applicable prices, requested ship dates,
destination of shipment and other details related to a specific order. All purchase orders and requested ship dates are subject to written acceptance and acknowledgment by Smart Sand. 

1.7 The terms and conditions of this Agreement are the controlling terms and conditions for the purchase of Products by Buyer. The printed
terms and conditions of any purchase order, acknowledgment form, invoice or other business form of Buyer and Smart Sand shall not apply to any order. Buyer and Smart Sand agree that any purchase order issued by Buyer is for quantity and timing
purposes only, and such purchase order does not form the basis of any contract. 
 2. Price and Payment Terms 

2.1 The pricing for each of the Products for each Contract Year shall be as set forth on Appendix C attached hereto and incorporated by
reference (“Contract Price”). Smart Sand agrees that all Products ordered by Buyer and shipped prior to *** will be loaded onto Smart Sand supplied railcars, which have been provided in accordance with that certain Railcar Usage
Agreement, dated August 19, 2014, and subsequently amended and restated on the Execution Date, by and between Smart Sand and Buyer (as amended, the “Railcar Usage Agreement”), and shipped as specified in the purchase order,
provided, however, that (i) Buyer agrees to comply with all freight scheduling mechanisms and timeframes designated by Smart Sand in writing to Buyer from time to time, and (ii) delivery of the Products shall occur upon the
transfer of Products into the applicable railcar via a delivery chute. Delivery will be, and all prices are quoted, FCA Smart Sand’s facility in which such Products are loaded onto railcars (i.e. the Oakdale Facility, the Hixton Facility, or
such other facility as determined by the mutual consent of Smart Sand and Buyer), Incoterms 2010. For the avoidance of doubt, all rail and shipping costs, including, without limitation, insurance costs and in the event that all railcars subject to
the Railcar Usage 

  
 2 

 EXECUTION COPY 
  

 
Agreement are not returned in accordance with the terms of the Railcar Usage Agreement, an amount equal to *** per day per railcar for each day that any such railcars are not timely returned,
shall be borne exclusively by Buyer. Buyer shall use commercially reasonable efforts to establish a trade account with Smart Sand’s preferred rail carrier and transloader. Prior to the establishment of such trade accounts, Smart Sand shall pay
all freight charges and transloading charges for any shipment, after which Smart Sand shall provide an invoice to Buyer for such charges and Buyer shall pay Smart Sand within *** of the date of such invoice. After the establishment of such trade
accounts, Smart Sand may, at its option and with written notice to Buyer in response to the applicable purchase order that it intends to, pay all freight charges and transloading charges for any shipment, after which Smart Sand shall provide an
invoice to Buyer for such charges and Buyer shall pay Smart Sand within *** of the date of such invoice. The Contract Price shall be subject to adjustments implemented during the Term in accordance with the terms set forth in Appendix C. 

2.2 Unless stated otherwise in an order, prices quoted by Smart Sand do not include sales, VAT use or similar taxes. And such taxes, fees,
duties, and customs charges imposed on Smart Sand in the country or area of operations shall be reimbursed to Smart Sand by Buyer. The provisions of this clause shall continue after termination of this Agreement. 

2.3 Smart Sand shall invoice Buyer upon shipment of Products. Other than as provided for freight charges and transloading charges in
Section 2.1, payment by Buyer shall be due and payable within *** after the date of invoice. Past due invoices (including invoices for freight charges and transloading charges) are subject to a monthly service charge at a rate equal to *** per
month or the maximum rate from time to time permitted by applicable law. 
 2.4 Smart Sand’s Credit Department may revoke credit
approval at any time and require credit enhancements such as a prepayment or a letter of credit posted by Buyer to continue performing under this Agreement. Upon placing this instrument with an attorney for collection of past due payments or
repossession of Products, Buyer shall reimburse Smart Sand for reasonable attorneys’ fees, court costs, and other expenses incurred by Smart Sand to enforce the terms and conditions stated herein. 

2.5 Within *** after the Execution Date, Buyer shall pay to Smart Sand the amount of ***, representing payment in full for all True-Up
Payments (as defined in the Original Agreement) payable by Buyer with respect to Contract Year 1 of the Original Agreement (the “Prior Shortfall Payment”). Any failure by Buyer to pay the Prior Shortfall Payment when due shall
constitute a material breach of this Agreement, and, in addition to (and not in lieu of) any other rights and remedies that Smart Sand has, the Prior Shortfall Payment shall automatically and without notice accrue interest at a rate equal to *** per
month or the maximum rate from time to time permitted by applicable law, whichever is greater. 
 3. Specifications 

In the event Buyer desires to change the Specifications, a request for change shall be submitted to Smart Sand in writing. Smart Sand must
agree to any such changes in writing prior to amendment of the Specifications, and Smart Sand is under no obligation to accept any such changes. Smart Sand shall notify Buyer of any adjustment to the Contract Prices resulting from the changes to the
Specifications requested by Buyer. Buyer must agree to the adjustment to the Contract Prices in writing prior to any amendment of the Specifications. 

4. Delivery 
 4.1
The Products shall be delivered in accordance with Section 2.1 of this Agreement. Smart Sand reserves the right to charge Buyer a storage fee for any Buyer controlled rail car that remains at Smart Sand’s rail facility longer than ***
after arrival. 
 4.2 In the event that Smart Sand is unable to supply Buyer’s requirements, Buyer shall have the right to purchase
replacement Product (“Replacement Products”) from alternative sources (up to the amount that Smart Sand is unable to supply) after receipt of notification of Smart Sand’s failure to supply. Provided that

  
 3 

 EXECUTION COPY 
  

 
Smart Sand’s inability to supply is not the result of an Excusable Delay under Section 9 below, then all Replacement Products purchased by Buyer shall count towards the Buyer’s
requirements obligation set forth in Section 1.1 above. Except to the extent Smart Sand’s inability to supply is the result of an Excusable Delay, if the Replacement Products are purchased by Buyer at a price that is higher than the
then-applicable Contract Price, Smart Sand shall be responsible for the difference between the Contract Price and the price of the Replacement Products, which may be paid by shipping additional Products or providing a credit to Buyer towards future
purchases of Products. 
 4.3 In connection herewith, until *** Buyer shall borrow railcars from Smart Sand, pursuant to the Railcar Use
Agreement (the “Railcar Use Agreement”), substantially in the form attached hereto as Exhibit A. Commencing ***, Buyer shall be responsible for supplying all railcars required to load and transport all Product purchased hereunder
from Smart Sand to the Buyer. Any failure by Buyer to supply any such railcars shall not reduce or limit in any way any of Buyer’s obligations hereunder, including but not limited to, its obligation to purchase the Minimum Tons Per Year of
Products *** set forth in Section 1.1. 
 5. Inspection 

Smart Sand shall test the Products in accordance with the testing procedures set forth on Appendix D for compliance with the
Specifications. Smart Sand shall retain all testing records for a period of *** and shall, at Buyer’s request, supply to Buyer a copy of Smart Sand’s test sheets, certified by Smart Sand to be a true copy. Because deliveries made pursuant
to this Agreement shall be via large individual loads by rail, any inspection by Buyer can be made at the point of loading. Buyer may, at its expense, have a representative at Smart Sand’s facility for the purpose of such inspection. 

6. Warranty 
 6.1
Smart Sand warrants to Buyer that Smart Sand shall conform with the Specifications and comply in all material respects with the testing procedures set forth on Appendix D attached hereto and incorporated by reference with respect to each
Product. If Buyer and Smart Sand agree in good faith that any Product sold under this Agreement does not meet the Specifications, Smart Sand, at its cost and expense, shall promptly correct the defect by either (i) delivering substitute Product
meeting the Specifications, or (ii) refunding any amounts paid to Smart Sand for such non-conforming Product. 
 6.2 Buyer acknowledges
that Products may become damaged by improper handling after delivery and that Smart Sand shall have no obligation to replace such damaged Products. 

6.3 THIS WARRANTY IS EXPRESSLY IN LIEU OF ALL OTHER WARRANTIES. SMART SAND MAKES NO OTHER WARRANTIES, EXPRESS OR IMPLIED, INCLUDING BUT NOT
LIMITED TO ANY WARRANTIES OF MERCHANTABILITY OR FITNESS FOR ANY PARTICULAR PURPOSE WITH RESPECT TO ANY PRODUCTS. 
 7. Term and
Termination 
 7.1 This Agreement shall become effective as of *** (the “Effective Date”), and shall expire at 11:59
p.m. on the last day of *** (the “Term”) unless sooner terminated as provided herein. 
 7.2 Either party may terminate
this Agreement, immediately upon written notice to the other party, (i) if such other party is in material breach of any of its obligations under the Agreement and fails to cure such breach within *** (*** for the nonpayment of money) after
written notice thereof to such other party, or (ii) if such other party is insolvent or makes any arrangement with its creditors generally, or has a receiver appointed for all or a substantial part of its business or properties, or an
insolvency, bankruptcy or similar proceeding is brought by or against such other party and involving such other party is not dismissed within 60 business days of its institution, or if such other party goes into liquidation or otherwise ceases to
function as a going concern.

 EXECUTION COPY 
  

 7.3 In the event of termination of this Agreement as provided in Section 7.2, this
Agreement shall immediately become void and there shall be no liability or obligation on the part of any party hereto; provided, that (i) any such termination shall not relieve any party from liability for any willful breach of
this Agreement or any fraud, (ii) the provisions of this Section 7.3 (Effect of Termination) and Sections 8 (Confidentiality), 10 (Limitation of Liability), 12 (Notices), 13 (Resolution of Disputes), 14 (Compliance with Laws) and 15
(Miscellaneous) of this Agreement shall remain in full force and effect and survive any termination of this Agreement, and (iii) if termination is by Smart Sand, Buyer shall pay, within *** of the effective date of termination, an amount equal
to: 
  

	 	(A)	all amounts due and owing to Smart Sand for Products delivered by Smart Sand prior to the effective date of termination; plus 

 

	 	(B)	an amount equal to: (i) *** of the then-applicable Contract Price for each of the *** Products, multiplied by (ii) the difference between (X) the Minimum Tons per Year for ***, as may be adjusted pursuant
to Section 1.3 and (Y) the actual tons of each Product purchased by Buyer during ***; minus any payments made by Buyer to Smart Sand under Section 1.5; plus 

 

	 	(C)	all amounts due or to become due to Smart Sand under the Railcar Use Agreement. 

 8.
Confidentiality 
 8.1 The parties acknowledge that either party may disclose (orally or in writing) to the other confidential and
proprietary information relating to the Products or each party’s business (together the “Confidential Information”). Each party agrees that it will keep the Confidential Information of the other party disclosed to it in
confidence by using at least the same degree of care to prevent unauthorized disclosure or use thereof as such party uses to protect its own confidential information of like nature, and that it will not knowingly disclose, directly or indirectly,
any item of Confidential Information to any person, without the prior written consent of the disclosing party, except only to those of the recipient’s employees who need to know the same in the performance of their duties for the recipient in
connection with this Agreement. 
 8.2 The parties’ non-disclosure obligations restrictions hereunder shall continue with respect to
any item of Confidential Information until the earlier of the expiration of ten (10) years following the termination of this Agreement for any reason, or until such item: (a) is or has become publicly available; or (b) was in the
possession of, or known by, the recipient without an obligation to keep it confidential; or (c) has been disclosed to the recipient by an unrelated third party, without an obligation to keep it confidential; or (d) has been independently
developed by the recipient. 
 9. Excusable Delay 

Neither party shall be liable for any delay or failure to perform to the extent caused by fire, flood, adverse weather conditions, explosion,
war, riot, embargo, labor disputes, strike, shortage of utilities, delay in transportation, compliance with any laws, regulations, orders, acts or requirements from the government, civil or military authorities, government-mandated facility
shutdowns or limitations, acts of God or the public enemy, or any other similar act or event of any nature reasonably beyond such party’s control. In such circumstances, neither party shall be liable for its failure to perform its obligations
hereunder to the limited extent that such failure is due to an event hereunder; provided, however, that (i) such non-performance shall only be permitted during the duration of such event, and (ii) a party legitimately
claiming such event shall be obligated to remedy the applicable event with all reasonable and diligent dispatch; and provided, further, that the party claiming such event shall use commercially reasonable efforts to take such actions
as such party deems necessary or advisable to mitigate the negative impact of such event on the other party. If Smart Sand’s production capacity is impaired as a result of one of the foregoing events of force majeure, then Smart Sand will
allocate to Buyer a pro rata portion of Smart Sand’s total remaining capacity taking into account Smart Sand’s impaired production capacity, Buyer’s requirements pursuant to the forecast provided by Buyer in accordance with
Section 1.2, and Smart Sand’s aggregate requirements for Products under purchase agreements with other customers.

 13. Resolution of Disputes 

13.1 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. 
 13.2 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 respective
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 and forum
provisions and the respective parties agree not to avail themselves of such alternate local legislation or remedies available thereunder. The parties acknowledge that this is a fundamental foundation for the risk allocation undertaken in this
Agreement and should this provision be breached it would deny the other party the full benefit of its risk allocation and the agreed pricing structure. Accordingly, should a party avail itself of local legislation that conflicts or negates the risk
allocation contained in this Agreement, then such party shall be liable to the non-breaching party for all damages arising therefrom. 

14. Compliance with Law 

14.1 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 compliance in all material respects 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. 
 14.2 Notwithstanding anything to the contrary, neither party shall be required to take any action or be
required to refrain from taking any action prohibited, penalized or required, as applicable, under the laws of the United States, including, without limitation, the U.S. antiboycott laws. 

15. Miscellaneous. 

15.1 This Agreement constitutes the entire agreement between the parties hereto relating to the subject matter hereof and supersedes all prior
oral and written and all contemporaneous oral negotiation, commitments and understandings of the parties. This Agreement may not be changed or amended except by a writing executed by both parties hereto. 

15.2 This Agreement shall inure to the benefit of and be binding upon the parties hereto and their respective successors and assigns (to the
extent this Agreement is assignable). Either party may assign or otherwise transfer this Agreement without the other party’s consent to (i) one of its affiliates, (ii) the purchaser of substantially all of such party’s assets,
(iii) the surviving entity in a merger involving such party or (iv) any financial institution providing financing to such party. Except for such assignment, no party may assign this Agreement without the prior written consent of the other
party. Any prohibited assignment or attempted assignment without the other party’s prior written consent shall be void.

 EXECUTION COPY 
  

 15.3 This Agreement shall be governed by and construed and enforced in accordance with the
internal laws of the State of Delaware without giving effect to that state’s conflicts of laws principles or choice of law rules. The parties agree that Wilmington, Delaware shall be the exclusive forum and venue for resolving any disputed
matter. 
 15.4 No delay or failure by either party to exercise or enforce at any time any right or provision of this Agreement shall be
considered a waiver thereof or of such party’s right thereafter to exercise or enforce each and every right and provision of this Agreement. A waiver to be valid shall be in writing, but need not be supported by consideration. No single waiver
shall constitute a continuing of subsequent waiver. 
 15.5 The rights and obligations of the parties hereto shall survive the termination
or expiration of this Agreement to the extent that any performance is required under this Agreement after such termination or expiration. 

15.6 This Agreement may be executed in one or more counterparts, each of which shall be deemed an original, but all of which shall constitute
one and the same document. 
 15.7 The headings herein are for reference purposes only and are not to be considered in construing this
Agreement. 
 15.8 If any provision of this Agreement shall be held illegal, invalid or unenforceable, in whole or in part, such provision
shall be modified to render it legal, valid and enforceable while to the fullest extent possible preserving the business and financial intent and impact of the original provision, and the legality, validity and enforceability of all other provisions
of the Agreement shall not be affected thereby.

Product Pricing 

Contract Prices are the sum of annual Base Prices and Quarterly fuel surcharges, as detailed below. Pricing for shipments each month should
be based on the Contract Prices for the most recent quarter. 
  

	 	1)	Base Prices starting during *** will be based upon the Average Cushing Oklahoma WTI Spot Prices as listed on WWW.EIA.DOE.GOV for the preceding calendar quarter (the “Oil Price Average”) ((Month 1
Average + Month 2 Average + Month 3 Average)/3=Oil Price Average) as follows: 

  

									
	 	  	Base Price Based Upon Preceding Calendar Quarter Oil Price
Average (per barrel)
	Product	  	Less than $***	 	 At least $***

and less than

$***
	 	 At least $***

and less than

$***
	 	At least $***
	 ***
	  	***	 	***	 	***	 	***

  

	 	2)	Base Prices are subject to quarterly diesel and natural gas/propane fuel surcharges adjustments, starting on the Execution Date, with details below: 

Natural Gas Surcharge: A Natural Gas Surcharge will be applied if the Average Natural Gas Price (ANGP) as listed on
WWW.EIA.DOE.GOV for the preceding calendar quarter is above the Bench Mark, set at *** per MMBTU, and shall be adjusted at the end of each calendar quarter for the duration of the Agreement. A surcharge of *** per ton for every *** per MMBTU
increase for the ANGP for the preceding calendar quarter will apply in addition to the Base Price for all products. The calculation will be prorated, i.e., if the ANGP for a prior quarter averages *** per MMBTU, the surcharge will be *** per ton for
the following quarter. 
 As an example, if the average of the monthly closes of NYMEX natural gas for January, February and March is ***,
then ***will be added to the applicable Base Price for April, May and June. Additionally, if the average of the monthly closes of NYMEX natural gas for April, May and June is *** or less, then *** will be added to the Base Price for July August and
September. 
 Propane Surcharge: A Propane Surcharge will be applied if the Average Quarterly Mont Belvieu, TX Propane Spot Price
(AMBTX) as listed on WWW.EIA.GOV (http://www.eia.gov/dnav/pet/hist/LeafHandler.ashx?n=pet&s=eer_epllpa_pf4_y44mb_dpg&f=m) for the preceding calendar quarter is above the Bench Mark, set at *** per gallon of Propane ((Month 1 Average +
Month 2 Average + Month 3 Average)/3=AMBTX), and shall be adjusted at the end of each calendar quarter for the duration of the Agreement. A surcharge of $*** per ton for every *** per gallon increase in the AMBTX for the preceding calendar quarter
will apply in addition to the Base Price for all products. The calculation will be prorated, i.e., if the AMBTX for a prior quarter averages *** per Gallon, the surcharge will be *** per ton for the following quarter. 

As an example, if the average of the monthly closes of Mont Belvieu, TX Propane Spot for January, February and March is ***/gallon, then ***
will be added to the applicable Base Price for April, May and June. Additionally, if the average of the monthly closes of AMBTX propane for April, May and June is ***/gallon or less, then *** will be added to the Base Price for July August and
September.

 AMENDED AND RESTATED RAILCAR USAGE AGREEMENT 

THIS AMENDED AND RESTATED RAILCAR USAGE AGREEMENT (“Agreement”) is made as of this 16th day of December 2015, by and between
Smart Sand, Inc., having an address of 1010 Stony Hill Rd, Ste 175, Yardley, PA 19067 (“Smart Sand”); and Archer Pressure Pumping, LLC, having an address of 10613 W. Sam Houston Pkwy N., Suite 600, Houston Texas 77064
(“Borrower”). 
 BACKGROUND 

A. Smart Sand has agreed to sell to Borrower frac sand pursuant to a Master Product Purchase Agreement, dated August 19, 2014, as amended
and restated by that certain Amended and Restated Master Product Purchase Agreement, dated of even date herewith (as amended and restated, the “Restated PPA”), which frac sand shall be shipped from Smart Sand’s facility via
railcar. 
 B. Smart Sand and Borrower are parties to that certain Railcar Usage Agreement, dated as of August 19, 2014 (the
“Original Agreement”); and 
 C. Smart Sand and Borrower desire to amend and restate in its entirety the Original
Agreement, as set forth in this Agreement, to provide for the terms under which Smart Sand will lend to Borrower, and Borrower will use, *** railcars during the period ending ***. 

NOW, THEREFORE, for good and valuable consideration, the receipt and sufficiency of which is hereby acknowledged, the parties, intending to be
legally bound, hereby agree as follows: 
 1. Term. The term of this Agreement shall commence on the date hereof and expire upon the
termination or ***. All borrowed railcars will be returned to the Facility (as defined below), or another facility or location designated by Smart Sand, and all outstanding fees must be paid to Smart Sand within 30 days of termination. 

2. Railcar Usage. Smart Sand and Borrower hereby agree as follows: 

A. Smart Sand shall provide railcars exclusively to Borrower and Borrower shall use such railcars solely for the purpose of shipping frac sand
pursuant to the Restated PPA from Smart Sand’s Oakdale, Wisconsin facility (the “Facility”). During the term, Borrower shall pay to Smart Sand a monthly fee of *** (consisting of *** for the railcar and *** for insurance
coverage) for each railcar (plus all costs associated with the initial delivery of such railcar by the owner/lessor of such railcar (the “Owner”) to Smart Sand, such costs not to exceed *** per car) set forth on Schedule A
attached hereto, which schedule may be amended at any time and from time to time upon the written consent of both parties as required to ship the volume of products to Borrower set forth in the Restated PPA. Smart Sand agrees to add the Borrower as
an “additional insured” to its insurance policy relating to the railcars, and in good faith to pursue abatements, reductions and concessions from Owner on the number of railcars under rental and the monthly fee per railcar, and to provide
the Borrower with the benefit of any rent abatement, reduction or other concession that Smart Sand may receive from the Owner. Notwithstanding the foregoing, Borrower shall not have the right to review all or any portion of the railcar lease between
the Owner and Smart Sand, unless otherwise consented to in writing by the Owner and Smart Sand. Once delivery of a frac sand shipment pursuant to the Restated PPA has been completed, Borrower shall use commercially reasonable efforts to ensure the
prompt return of all borrowed railcars to the Facility. During the period commencing on the date hereof and ending on ***, Borrower may sublease any railcars borrowed hereunder to one or more third parties upon (i) Borrower entering into a
mutually agreeable sublease with Smart Sand, which sublease shall contain standard and customary terms and conditions, shall provide that Borrower shall pay to Smart Sand a rate of *** per railcar, and shall be subject to the Owner’s review,
feedback and approval, and (ii) Borrower entering into a sublease with the third party that is leasing the railcars from Borrower, which sublease shall contain standard and customary terms and conditions and shall be subject to the Owner’s
review, feedback and approval. Upon expiration of this Agreement in accordance with its terms, Borrower shall promptly, but in no event greater than *** after such termination or expiration, return all railcars to the Facility and pay to Smart Sand
all amounts due and payable hereunder. If the Restated PPA is terminated or expires prior to ***, then Borrower shall promptly, but in no event greater than *** after the termination or expiration of the Restated PPA, return all railcars to the
Facility and pay to Smart Sand, in addition to all amounts due and payable hereunder, all remaining payments to become due to Smart Sand hereunder plus all early termination fees payable by Smart Sand to all Owners of the railcars pursuant to Smart
Sand’s lease with such Owners. By way of example, if the Restated PPA terminates and *** are borrowed pursuant to this Agreement, and, but for the Restated PPA’s termination there would have been twelve (12) months remaining under the
term of this Agreement, the accelerated sum of *** will become immediately due and payable

to Smart Sand (12 months x *** cars x ***), plus all fees payable by Smart Sand to each Owner pursuant to its lease. Notwithstanding the foregoing, if, at the time of termination or expiration,
another customer has expressed to Smart Sand an interest in borrowing railcars from Smart Sand (and Borrower has not exercised its right to sublease the railcars as set forth above), then Smart Sand shall use reasonable efforts to provide all or any
portion of the railcars subject to this Agreement to such customer, after which Borrower shall have no further obligation to pay monthly fees for any railcar transferred to such customer (so long as such customer is paying a monthly fee of at least
*** per car per month); provided, however, that Borrower shall remain fully liable to pay for any railcars that are not transferred in accordance with the provisions above; and provided, further, that Borrower shall
promptly reimburse Smart Sand for all expenses incurred by Smart Sand in transferring such railcars to such customer (including, without limitation, reasonably attorneys’ fees and transportation expenses), and, if such customer pays a rate less
than the *** per car per month, then Borrower shall promptly pay to Smart Sand an amount equal to the difference between *** and the amount paid by such new customer, multiplied by the number of cars transferred to such customer, multiplied by the
number of months remaining in this Agreement (((***-New Customer Rate) * Number of Transferred Cars) * Number of Remaining Months). 
 B.
Borrower will preserve in good condition Smart Sand’s railcars and will not alter the structure of such railcars. The railcars shall be used exclusively within the continental United States and/or between Canada and the continental United
States. All cross border fees/duty/taxes associated with usage of the railcars to and from Canada shall be borne by the Borrower. The Borrower shall return the borrowed cars empty and clean. 

C. During the time while the railcars are borrowed, Borrower assumes the entire responsibility for the railcars and shall be responsible and
liable to Smart Sand for any and all damage to or destruction of same, except for damage caused by normal wear and tear and for damage that is covered under Smart Sand’s insurance policy related to the railcars. Smart Sand shall not be liable
for loss of or damage to the product or any part thereof that may be handled or stored in the borrowed railcars. Borrower assumes responsibility for, and indemnifies and holds Smart Sand harmless from, any such loss or damage or claim therefore,
except where such loss or damage is caused solely by Smart Sand’s negligence. Borrower indemnifies and holds Smart Sand harmless from any liability resulting from injuries to persons or damage to property arising out of or in connection with
the use of borrowed railcars except when caused solely by Smart Sand’s negligence. 
 3. Amounts Payable. The parties agree that
the outstanding amounts due and payable under Section 2A of the Original Agreement for or with respect to period prior to the date hereof are reflected on Invoice No. *** and that such amounts shall be paid in accordance with the terms of such
invoices. 
 4. Relationship of Parties. Smart Sand and Borrower acknowledge and agree that their relationship is that of contracting
parties and independent contractors only, and neither is the partner, employee, joint venturer or agent of the other. 
 5. Governing
