After the Additional Tonnage Commencement Date (assuming the Excess Capacity Commencement Date (as defined below) has not occurred), the Minimum Tons per Year and Minimum Tons per Quarter shall be as follows:

*The Additional Tons shall be prorated in the Contract Year and quarter in which the Additional Tonnage Commencement Date occurs based upon the days remaining in such Contract Year and quarter.

Excess Capacity Tonnages

Smart Sand shall use commercially reasonable efforts to obtain up to an additional *** railcars for purposes of shipping an additional *** tons of Products per Contract Year. Commencing on the *** (the “Excess Capacity Commencement Date”) after Smart Sand notifies Buyer in writing that it has excess capacity available to sell an additional *** tons of Products per Contract Year, and has an additional *** railcars available for shipment of such additional Products and, pursuant to subsection (2) of Appendix C, the parties mutually agree on an increased per ton railcar usage charge (if necessary), the Minimum Tons per Year and Minimum Tons per Quarter shall be increased by *** tons per Contract Year and *** tons per quarter (“Excess Capacity Tons”).

ACTIVE\49362770.v2-5/30/17

(ii)If Smart Sand determines, in its reasonable discretion (and notifies Buyer in writing of its determination), that the railcars designated for shipping either the Additional Tons or the Excess Capacity Tons (i.e. *** railcars and *** railcars, as applicable), are insufficient for shipping the Additional Tons or Excess Capacity Tons, as the case may be, the Additional Tons or the Excess Capacity Tons (and the Minimum Tons per Year and Minimum Tons per Quarter), as the case may be, shall be automatically reduced by an amount equal to *** tons multiplied by the number of additional railcars required to ship the Additional Tons or the Excess Capacity Tons, as the case may be, as determined by Smart Sand in its reasonable discretion; provided, however, that if either Smart Sand or Buyer supplies additional railcars after such reduction, the Additional Tons or Excess Capacity Tons (and the Minimum Tons per Year and Minimum Tons per Quarter), as the case may be, shall automatically increase at a rate equal to the number of additional railcars supplied by Smart Sand or Buyer multiplied by *** (i.e. Additional railcars* ***), up to the amounts set forth subsection (i) above.

(iii)Nothing in this Agreement shall be construed as limiting either party’s right to enter into a purchase or sale agreement with respect to any of the Products with a third party at any time.”

1.2Section 1.3 shall be deleted in its entirety and replaced with the following:

“1.3In no event will Smart Sand be required to provide to Buyer, in any given month during the Term, an aggregate amount exceeding *** percent of the then-applicable Minimum Tons per Year. Buyer shall submit purchase orders on or before the 15th day of each month in order for the Products set forth in such purchase orders to be deemed to be purchased in such month. Buyer shall submit purchase orders containing evenly spaced delivery intervals and similar quantities of Products.”

1.3The first paragraph of Section 1.5 shall be deleted in its entirety and replaced with the following:

“1.5Buyer may choose to defer the purchase of up to a maximum of *** percent of the then-applicable Minimum Tons per Year each Contract Year until the end of the Term (each ton, a “Deferred Ton”). Within *** after completion of each Contract Year or earlier termination of this Agreement (each, a “Determination Date”), Buyer shall pay to Smart Sand (each, a “Deferment Payment”) an amount equal to the applicable Contract Price for the Deferred Tons multiplied by the amount of Deferred Tons on such Determination Date. If Buyer purchases more than the Minimum Tons per Quarter in any quarter, (i) such excess shall automatically reduce the Deferred Tons, and (ii) in the following quarter, the Prior Excess shall be reduced by the amount of such excess. By way of example, (i) if the Minimum Tons per Year is *** tons, the Deferred Tons are *** tons and Buyer purchases *** tons in a quarter, then the Deferred Tons will be automatically decreased to *** and the Prior Excess will be ***, and (ii) if Buyer then purchases *** tons of Products in the subsequent quarter, the Deferred Tons will be reduced to *** and the Prior Excess will be *** tons. If Buyer does not pay any Quarterly Shortfall Payment when due (and fails to cure such nonpayment within *** after such Quarterly Shortfall Payment is due), Smart Sand may, in its sole discretion, eliminate Buyer’s deferral right

hereunder by providing written notice of such elimination to Buyer, in which case Buyer shall promptly (but in no event greater than *** after Smart Sand’s notice) pay to Smart Sand (A) an amount equal to $*** multiplied by the then outstanding Deferred Tons, and (B) any outstanding Deferment Payments. At no time during any Contract Year during the Term may the Deferred Tons exceed *** percent of the Minimum Tons per Year.”

1.4The parenthetical in the second sentence of Section 2.1 stating “(which Smart Sand railcars shall consist of up to *** railcars for Products)” shall be deleted in its entirety and replaced with “(which Smart Sand railcars shall be provided in accordance with the Railcar Usage Agreement)”.

1.5Appendix B to the Agreement shall be deleted in its entirety and replaced with Appendix B attached hereto.

1.6After the Additional Tonnage Commencement Date, all *** Products shall have the same Base Price as *** Products, as set forth in Appendix C to the Agreement.

1.7Subsection (2) of Appendix C shall be deleted in its entirety and replaced with the following:

“(2)Buyer shall pay to Smart Sand an additional $*** per ton of Products purchased or required to be purchased hereunder (or, if Smart Sand determines in its sole discretion that $*** per ton is insufficient for railcar usage for shipping the Additional Tons or Excess Capacity Tons, such higher amount as mutually agreed to by Smart Sand and Buyer in connection with the Additional Tons and Excess Capacity Tons), as set forth in more detail in the Railcar Usage Agreement.”
