12

(m)    Each Benefit Plan that is intended to be qualified under Section 401(a) of the Code has received a favorable determination letter or is entitled to rely on a favorable opinion letter from the IRS, in either case, that has not been revoked, and to the Knowledge of the Contributor Parties, no event or circumstance exists that has adversely affected or would reasonably be expected to adversely affect such qualified status. Each trust established in connection with any Benefit Plan which is intended to be exempt from federal income taxation under Section 501(a) of the Code is so exempt, and to the knowledge of such Contributor Party, no fact or event has occurred that would reasonably be expected to adversely affect the exempt status of any such trust.

(e)    There is no action, suit, proceeding, investigation, audit, dispute or claim concerning any Tax Return or any amount of Taxes of the Sponsor Entities either claimed or raised by any Governmental Authority in writing.

(f)    The Sponsor has made an election pursuant to Section 754 of the Code and such election is currently in effect.

(g)    There are no outstanding agreements or waivers extending the applicable statutory periods of limitation for any Taxes of the Sponsor Entities.

13

(j)    No Sponsor Entity has liability for Taxes of any Person under Treasury Regulation Section 1.1502-6 (or any similar provision of state, local or foreign Law), as a transferee, successor, or by Contract.

(k)    None of the Sponsor Entities has been a party to a transaction that is a “listed transaction,” as such term is defined in Treasury Regulations Section 1.6011-4(b)(2).

(l)    Hi-Crush Services and each Legacy Sponsor Subsidiary is classified as an entity disregarded as separate from the Sponsor for U.S. federal income tax purposes in accordance with Treasury Regulation § 301.7701-3. Sponsor is classified as a partnership for U.S. federal income tax purposes in accordance with Treasury Regulation § 301.7701-3. None of the Sponsor Entities has elected to be treated as a corporation for U.S. federal income Tax purposes.

(m)    Notwithstanding any other provision in this Agreement, (i) except to the extent that Taxes or the Code are explicitly referenced elsewhere, the representations and warranties in this Section 4.9 are the only representations and warranties in this Agreement with respect to the Tax matters of the Sponsor Entities, and (ii) none of the Sponsor Entities make any representation or warranty with respect to the existence, availability, amount, usability or limitations (or lack thereof) of any net operating loss, net operating loss carryforward, capital loss, capital loss carryforward, basis amount or other Tax attribute of any Sponsor Entities after the Closing Date.

Section 4.10    Litigation. There are no Proceedings pending or, to the Knowledge of the Contributor Parties, threatened before any Governmental Authority or arbitrator against the Sponsor Entities or the General Partner, except as would not, individually or in the aggregate, reasonably be expected to have a Sponsor Material Adverse Effect.

as of the date of this Agreement, shall survive the Closing and shall continue in full force and effect for a period of not less than the applicable statute of limitations.

(c)    In the event that any Sponsor Entity or the General Partner (i) consolidates with or merges into any other Person and shall not be the continuing or surviving corporation or entity of such consolidation or merger or (ii) in one or more series of transactions, directly or indirectly, transfers all or substantially all of its properties and assets to any Person (whether by consolidation, merger or otherwise), then, and in each such case, proper provision shall be made so that such continuing or surviving corporation or entity or transferee of such assets, as the case may be, assume the obligations set forth in this Section 6.6.

Section 6.7    Post-Closing Access; Records. From and after the Closing, the Partnership and its Affiliates shall make or cause to be made available to the Contributor Parties all books, records, Tax Returns and documents of the Hi-Crush Entities (and the assistance of employees responsible for such books, records and documents) upon reasonable notice during regular business hours as may be reasonably necessary for (a) investigating, settling, preparing for the defense or prosecution of, defending or prosecuting any Proceeding, (b) preparing reports to stockholders and Governmental Authorities or (c) such other purposes for which access to such documents is determined by the Contributor Parties to be reasonably necessary, including preparing and delivering any accounting or other statement provided for under this Agreement or otherwise, preparing Tax Returns, pursuing Tax refunds or responding to or disputing any Tax audit, or the determination of any matter relating to the rights and obligations of the Contributor Parties or any of their Affiliates under any Transaction Documents; provided, however, that access to such books, records, documents and employees shall not interfere with the normal operations of the Hi-Crush Entities and the reasonable out-of-pocket expenses of the Hi-Crush Entities incurred in connection therewith shall be paid by the Contributor Parties. The Partnership shall cause each Hi-Crush Entity to maintain and preserve all such Tax Returns, books, records and other documents for the greater of (i) five (5) years after the Closing Date and (ii) any applicable statutory or regulatory retention period, as the same may be extended and, in each case, shall offer to transfer such records to the Contributor Parties at the end of any such period.

Section 6.8    Tax Matters.

(a)    Transfer Taxes. Any transfer, documentary, sales, use, stamp, registration, and other similar Taxes and fees incurred in connection with this Agreement (“Transfer Taxes”) shall be borne equally by the Partnership, on the one hand, and the Contributor Parties, on the other hand. The Partnership and Contributor Parties shall cooperate to file all necessary Tax Returns and other documentation with respect to such Transfer Taxes, and, if required by applicable Law, the Parties agree to join in the execution of any such Tax Return and other documentation.

(b)    Allocation. On or prior to the date that is ninety (90) days after the Closing Date, the Contributor Parties’ Representative shall provide to the Partnership the Contributor Parties’ proposed allocation of the Consideration and other items treated as consideration for U.S. federal income tax purposes, which shall (i) allocate the Consideration (and the other items properly treated as consideration for U.S. federal income tax purposes) among the equity of the Partnership, the General Partner, and the Sponsor Entities indirectly transferred pursuant to this Agreement in accordance with Section 1060 of the Code and, to the extent applicable, Section 755 of the Code, and the Treasury Regulations thereunder, and (ii) in accordance with the amounts allocated to the equity of the General Partner and Sponsor Entities pursuant to clause (i), allocate such amounts among the assets of the General Partner and the Sponsor Entities in accordance with Section 1060 of the Code and, to the extent applicable, Section 755 of the Code, and the Treasury Regulations thereunder (the “Draft Allocation”). For the avoidance of doubt, the amounts allocated to the equity of to the Partnership pursuant to clause (i) of the preceding sentence shall be allocated among the assets of the Partnership for purposes of Sections 704(c), 751 and 755 of the Code consistent with the Partnership’s existing methodologies and current practices used for other transfers of equity in the Partnership, and nothing in the Draft Allocation or Tax Allocation shall require the Parties or the Partnership to use a different methodology. The Partnership shall have thirty (30) days after the receipt of the Draft Allocation to propose in writing any comments to the Draft Allocation (and in the event no such comments are proposed to the Contributor Parties within such time period, Partnership will be deemed to have agreed to, and accepted, the Draft Allocation). The Contributor Parties and the Partnership shall negotiate in good faith to agree upon a final allocation (the “Tax Allocation”). In the event that Partnership and the Contributor Parties are unable to agree upon a final allocation within thirty (30) days of Partnership’s delivery to the Contributor Parties of written comments to the Draft Allocation, the Parties may take inconsistent Tax reporting positions with respect to the allocation of the Consideration (and the other items properly treated as consideration for U.S. federal income tax purposes). In the event that the Parties agree upon a final Tax Allocation, Partnership and the Contributor Parties agree to (A) treat and report the transactions contemplated by this Agreement in all respects consistent with such Tax Allocation for purposes of any U.S. federal and applicable state income Taxes (including, but not limited to any statements required under Treasury Regulation § 1.751-1(a)(3) and any allocation required under Section 755 of the Code), and (B) not take any action inconsistent with such Tax Allocation; provided, however, that neither the Partnership nor the Contributor Parties shall be unreasonably impeded in its ability and discretion to negotiate, compromise and/or settle any Tax audit, claim or similar proceedings in connection with such allocation.

20

(c)    Cooperation. Prior to the destruction or discarding of any books and records with respect to Tax matters pertinent to the General Partner or any Sponsor Entity relating to any taxable period beginning on or before the Closing Date, each Party shall give the other Party reasonable written notice and, if the other Party so requests, shall itself allow, or cause the General Partner or Sponsor Entity to allow the other Party to take, possession of such books and records. Partnership and the Contributor Parties further agree, upon request, to use their reasonable best efforts to obtain any certificate or other document from any Governmental Authority or any other Person as may be necessary to mitigate, reduce or eliminate any Tax that could be imposed on the General Partner or a Sponsor Entity as a result of the transactions contemplated hereby or for any taxable period of the General Partner or Sponsor Entity beginning on or before the Closing Date.

(d)    Allocations. The Partnership and the Contributor Parties shall use commercially reasonable efforts to cause the Partnership to allocate all items of income, gain, loss, deduction and credit allocable to the Subject Units between Partnership and the Contributor Parties (as the owners of the Sponsor) based on the “interim closing method” under Section 706 of the Code and the Treasury Regulations thereunder.

(e)    Tax Indemnity.

(i)    The Contributor Parties, on a several and not joint basis, shall be liable for, shall pay and shall protect, defend, indemnify and hold harmless the Partnership and its Subsidiaries from and against all Losses such parties incur arising from (i) any breach of the representations and warranties contained in Section 4.9, (ii) any Taxes of the Sponsor Entities arising prior to and including the Closing Date, and (iii) any liability of each Sponsor Entity for the Tax of another Person as a result of being (A) a member of an affiliated, consolidated, combined or unitary group or (B) a party to any Contract providing for an obligation to indemnify any other Person for Tax. The Partnership shall be solely liable for, shall pay and shall protect, defend, indemnify and hold harmless the Contributor Parties from any and all Taxes which arise as a result of the ownership of the Sponsor Entities after the Closing Date.

(ii)    If any claim (an “Indemnified Tax Claim”) is made by any Tax Authority that, if successful, would result in indemnification of any Party (the “Tax Indemnified Party”) by another Party (the “Tax Indemnifying Party”) under this Section 6.8, the Tax Indemnified Party shall promptly, but in no event later than the earlier of (i) forty-five (45) days after receipt of notice from the Tax Authority of such claim or (ii) fifteen (15) days prior to the date required for the filing of any protest of such claim, notify the Tax Indemnifying Party in writing of such fact.

(iii)    The Tax Indemnifying Party shall control all decisions with respect to any Tax Proceeding involving an Indemnified Tax Claim and the Tax Indemnified Party shall take such action (including settlement with respect to such Tax Proceeding or the prosecution of such Tax Proceeding to a determination in a court or other tribunal of initial or appellate jurisdiction) in connection with a Tax Proceeding involving an Indemnified Tax Claim as the Tax Indemnifying Party shall reasonably request in writing from time to time, including the selection

21

of counsel and experts and the execution of powers of attorney; provided, however, that (i) within thirty (30) days after the notice required by Section 6.8(e)(ii) has been delivered (or such earlier date that any payment of Taxes with respect to such claim is due but in no event sooner than five days after the Tax Indemnifying Party’s receipt of such notice), the Tax Indemnifying Party requests that such claim be contested, and (ii) if the Tax Indemnified Party is requested by the Tax Indemnifying Party to pay the Tax claimed and sue for a refund, the Tax Indemnifying Party shall have advanced to the Tax Indemnified Party, on an interest-free basis, the amount of such claim. The Tax Indemnified Party shall not make any payment of an Indemnified Tax Claim for at least thirty (30) days (or such shorter period as may be required by Law) after the giving of the notice required by Section 6.8(e)(ii) with respect to such claim, shall give to the Tax Indemnifying Party any information requested related to such claim, and otherwise shall cooperate with the Tax Indemnifying Party in order to contest effectively any such claim.

(f)    Scope.

The rights under this Section 6.8 shall survive the Closing until thirty (30) days after the expiration of the statute of limitations (including extensions) applicable to such Tax matter. No claim may be made or brought by any Party hereto after the expiration of the applicable survival period unless such claim has been asserted by written notice specifying the details supporting the claim on or prior to the expiration of the applicable survival period. For the avoidance of doubt, this Section 6.8 shall not be subject to the provisions of Article VII.

Section 6.9    Waiver of Earnout Rights. By entering into this Agreement, each Contributor Party, on behalf of itself and its Affiliates, hereby waives, from and after the Closing, any and all rights related to, and acknowledges the termination of any obligations of any Partnership Entity in respect of, the Earnout Payments including, without limitation, the right of such Contributor Party and/or its Affiliates to receive any indirect payments thereunder, and acknowledges and agrees that the Contributor Parties and their Affiliates shall not have any further rights with respect thereto.

The Sponsor hereby waives, from and after the Closing, any and all rights related to, and acknowledges the termination of any obligations of the Partnership or Hi-Crush Augusta in respect of, any Earnout Payment contemplated by the 2017 Contribution Agreement (including any rights by the Sponsor to receive any payments thereunder) pursuant to the terms of Section 12.8 therein, and acknowledges and agrees that the Sponsor shall not have any further rights with respect thereto.

(a)    If any Indemnified Party receives notice of the assertion of any claim or of the commencement of any claim, action, or proceeding made or brought by any Person who is not a Party to this Agreement or any Representative of a Party to this Agreement (a “Third Party Claim”) with respect to which indemnification is to be sought from an Indemnifying Party, the Indemnified Party shall give such Indemnifying Party reasonably prompt written notice thereof, but in any event such notice shall not be given later than thirty (30) calendar days after the Indemnified Party’s receipt of notice of such Third Party Claim. Such notice shall describe the nature of the Third Party Claim in reasonable detail and shall indicate the estimated amount, if practicable, of the indemnifiable Loss that has been or may be sustained by the Indemnified Party. The Indemnifying Party will have the right to participate in or, by giving written notice to the Indemnified Party, to elect to assume the defense of any Third Party Claim at such Indemnifying

23

Party’s expense and by such Indemnifying Party’s own counsel; provided, that the counsel for the Indemnifying Party who shall conduct the defense of such Third Party Claim shall be reasonably satisfactory to the Indemnified Party. The Indemnified Party shall cooperate in good faith in such defense at such Indemnified Party’s own expense. If an Indemnifying Party elects not to assume the defense of any Third Party Claim, the Indemnified Party may compromise or settle such Third Party Claim over the objection of the Indemnifying Party, which settlement or compromise shall conclusively establish the Indemnifying Party’s liability pursuant to this Agreement.

(b)    (i) If, within 20 calendar days after an Indemnified Party provides written notice to the Indemnifying Party of any Third Party Claims, the Indemnified Party receives written notice from the Indemnifying Party that such Indemnifying Party has elected to assume the defense of such Third Party Claim as provided in this Section 7.3, the Indemnifying Party will not be liable for any legal expenses subsequently incurred by the Indemnified Party in connection with the defense thereof (unless the Indemnifying Party is also a party to such proceeding and the Indemnified Party determines in good faith that joint representation would be inappropriate based on a conflict of interest between the Indemnifying Party and the Indemnified Party, in which case the Indemnified Party shall have the right to engage not more than one firm as its own counsel, the fees and expenses of which shall be paid by the Indemnifying Party); provided, however, that if the Indemnifying Party shall fail to take reasonable steps necessary to defend diligently such Third Party Claim within 20 calendar days after receiving notice from the Indemnified Party that the Indemnified Party believes the Indemnifying Party has failed to take such steps, the Indemnified Party may assume its own defense and the Indemnifying Party shall be liable for all reasonable expenses thereof.

(ii)    Without the prior written consent of the Indemnified Party, the Indemnifying Party shall not enter into any settlement of any Third Party Claim that would lead to liability or create any financial or other obligation on the part of the Indemnified Party for which the Indemnified Party is not entitled to indemnification hereunder. If a firm offer is made to settle a Third Party Claim without leading to liability or the creation of a financial or other obligation on the part of the Indemnified Party for which the Indemnified Party is not entitled to indemnification hereunder and the Indemnifying Party desires to accept and agree to such offer, the Indemnifying Party shall give written notice to the Indemnified Party to that effect. If the Indemnified Party fails to consent to such firm offer within 30 calendar days after its receipt of such notice, the Indemnifying Party shall be relieved of its obligations to defend such Third Party Claim and the Indemnified Party may contest or defend such Third Party Claim. In such event, the maximum liability of the Indemnifying Party as to such Third Party Claim will be the amount of such settlement offer plus reasonable costs and expenses paid or incurred by Indemnified Party up to the date of said notice.

(c)    Any claim by an Indemnified Party on account of an indemnifiable Loss that does not result from a Third Party Claim (a “Direct Claim”) shall be asserted by giving the Indemnifying Party reasonably prompt written notice thereof, stating the nature of such claim in reasonable detail and indicating the estimated amount, if practicable, but in any event such notice shall not be given later than 30 calendar days after the Indemnified Party becomes aware of such Direct Claim, and the Indemnifying Party shall have a period of 20 calendar days within which to respond to such Direct Claim. If the Indemnifying Party does not respond within such 20 calendar day period, the Indemnifying Party shall be deemed to have accepted such claim. If the Indemnifying Party rejects such claim, the Indemnified Party will be free to seek enforcement of its right to indemnification under this Agreement.

24

(d)    If the amount of any indemnifiable Loss, at any time subsequent to the making of an indemnity payment in respect thereof, is reduced by recovery, settlement or otherwise under or pursuant to any insurance coverage, or pursuant to any claim, recovery, settlement or payment by, from or against any other entity, the amount of such reduction, less any costs, expenses or premiums incurred in connection therewith (together with interest thereon from the date of payment thereof to the date or repayment at the “prime rate” as published in The Wall Street Journal) shall promptly be repaid by the Indemnified Party to the Indemnifying Party.

(e)    A failure to give timely notice as provided in this Section 7.3 shall not affect the rights or obligations of any Party hereunder except if, and only to the extent that, as a result of such failure, the Party that was entitled to receive such notice was actually prejudiced as a result of such failure.

(f)    Notwithstanding anything to the contrary in this Section 7.3, the indemnification procedures set forth in Section 6.8 shall control any indemnities relating to Taxes.

Section 7.4    Exclusive Remedy. Except for the remedies contained in Section 6.8 relating to Taxes, Section 8.8 and in the case of fraud, after the Closing, the Partnership acknowledges that the indemnification obligations of the Contributor Parties set forth in Section 7.2 are the sole and exclusive remedy of the Partnership Entities with respect to this Agreement and the transactions contemplated hereby, whether asserted against (a) the Contributor Parties or the Sponsor Entities or (b) the former, current and future holders of any equity, partnership or limited liability company interest, controlling persons, directors, officers, employees, agents, attorneys, Affiliates, members, managers, general or limited partners, stockholders, assignees of the or any of the Contributor Parties or the Sponsor Entities. Subject to and in furtherance of the foregoing, the Partnership hereby waives, from and after the Closing, to the fullest extent permitted under applicable Law, any and all rights, claims and causes of action it may have relating to the subject matter of this Agreement based upon predecessor or successor liability, contribution, tort, strict liability or any Law or otherwise.

Section 7.5    Limitations. Notwithstanding anything to the contrary in this Article VII or elsewhere in this Agreement (other than Section 6.8 relating to Taxes):

(a)    Each Contributor Party’s aggregate liability under this Agreement and from the transactions contemplated hereby shall not exceed its pro rata share of the value of the Consideration.

(b)    Each Indemnified Party shall take, and cause its Affiliates to take, commercially reasonable steps to mitigate any Loss for which it would otherwise be entitled to indemnification pursuant to this Article VII upon becoming aware of any event or circumstance that would be reasonably expected to, or does, give rise thereto, including incurring costs only to the minimum extent necessary to remedy the breach that gives rise to such Loss; provided that any reasonable cost incurred by a Party to mitigate any such Loss will be deemed a Loss for purposes of this Article VII.

25

(c)    NOTWITHSTANDING ANYTHING TO THE CONTRARY IN THIS AGREEMENT, NEITHER THE PARTNERSHIP NOR THE CONTRIBUTOR PARTIES NOR THEIR RESPECTIVE AFFILIATES SHALL BE LIABLE HEREUNDER TO ANY INDEMNIFIED PARTY FOR ANY LOST PROFITS OR PUNITIVE, CONSEQUENTIAL, REMOTE, SPECULATIVE, SPECIAL OR INDIRECT DAMAGES, EXCEPT TO THE EXTENT SUCH LOST PROFITS OR DAMAGES ARE INCLUDED IN ANY ACTION BY A THIRD PARTY AGAINST SUCH INDEMNIFIED PARTY FOR WHICH IT IS ENTITLED TO INDEMNIFICATION UNDER THIS AGREEMENT.

Section 7.6    Tax Treatment of Indemnity Provisions. Each Party, to the extent permitted by applicable Law, agrees to treat any payments made pursuant to this Article VII as adjustments to the Consideration for all U.S. federal and applicable state income and franchise Tax purposes.

Section 7.7    Calculation of Losses. In calculating amounts payable to an Indemnified Party, the amount of any indemnified Losses shall be computed net of (a) payments actually recovered by any Indemnified Party under any insurance policy with respect to such Losses net of expenses and (b) any actual recovery by any Indemnified Party from any Person with respect to such Losses net of expenses. Each Indemnified Party shall use commercially reasonable efforts to pursue reimbursement for Losses, including under insurance policies and indemnity arrangements.

Section 7.8    No Duplication. In no event shall any Indemnified Party be entitled to recover any Losses under one Section or provision of this Agreement to the extent of the full amount of such Losses already recovered by such Indemnified Party, nor shall its insurer or indemnitor be entitled to any kind of subrogation or substitution which would give it the right to make a claim against the Indemnifying Party.

Section 7.9    Release.

(a)    Except for the obligations of the Partnership under this Agreement or any Transaction Document and in the case of fraud, effective as of the Closing, each Contributor Party hereby forever fully and irrevocably releases and discharges each Hi-Crush Entity and its respective predecessors, successors and past and present stockholders, directors, managers, officers, employees, agents, and other representatives (collectively, the “Hi-Crush Released Parties”) from any and all actions, suits, claims, demands, debts, promises, judgments, liabilities or obligations of any kind whatsoever in law or equity and causes of action of every kind and nature, or otherwise (including claims for damages, costs, expense, and attorneys’, brokers’ and accountants fees and expenses) in each case related directly to such Contributor Party’s ownership of any of the Subject Units and the ownership and/or operation of the Sponsor Entities, or the assets, business, operations conduct, services, products and/or employees (including former employees) or any of the Sponsor Entities (and any predecessors), related to any period of time before the Closing Date, which each such Contributor Party can, shall or may have against the Hi-Crush Released Parties, whether known or unknown, and that now exist or may hereinafter accrue based on matters now known or unknown (collectively, the “Hi-Crush Released Claims”), and hereby irrevocably agrees to refrain from directly or indirectly asserting any claim or demand or commencing (or causing to be commenced) any proceeding of any kind before any Governmental Authority, against any Hi-Crush Released Party based upon any Hi-Crush Released Claim.
