  (i)            in each Taxable Year ending on or after such Early Termination Date,
      the Corporate Taxpayer will have taxable income sufficient
      to fully utilize the deductions arising from all Basis Adjustments and Imputed Interest, during such Taxable Year or future Taxable
      Years (including, for the avoidance of doubt, Basis Adjustments and Imputed Interest that would result from future Tax Benefit
      Payments that would be paid in accordance with the Valuation Assumptions, further assuming such future Tax Benefit Payments would
      be paid on the due date, including all valid extensions, for filing the Corporate Taxpayer Return for the applicable Taxable Year)
      in which such deductions would become available;

   

  

  
    10 

    
      

    

  

   

  (ii)           all taxable income of the Corporate Taxpayer will be subject to the
      maximum applicable tax rates throughout the relevant period;
      provided, the combined tax rate for U.S. state and local income taxes (but not, for the avoidance of doubt, federal income
      taxes) shall be the Assumed State and Local Tax Rate;

   

  (iii)          any loss or credit carryovers generated by deductions or losses
      arising from any Basis Adjustment and any Imputed Interest (including
      such Basis Adjustment or Imputed Interest generated as a result of payments under this Agreement) that are available in the Taxable
      Year that includes the Early Termination Date will be utilized by the Corporate Taxpayer ratably in each Taxable Year over the
      five Taxable years beginning with the Taxable Year that includes the Early Termination Date;

   

  (iv)          the U.S. federal, state and local income and franchise tax rates that
      will be in effect for each Taxable Year ending on or after
      such Early Termination Date will be those specified for each such Taxable Year by the Code and other law as in effect on the Early
      Termination Date;

   

  (v)           any non-amortizable Reference Assets to which any Basis Adjustment is
      attributable will be disposed of in a fully taxable transaction
      for U.S. federal income tax purposes on the fifteenth anniversary of the Early Termination Date for an amount sufficient to fully
      utilize the Basis Adjustment with respect to such non-amortizable Reference Asset; provided, that in the event of a Change
      of Control which includes a taxable sale of such non-amortizable Reference Asset (including the sale of all of the equity interests
      in an entity classified as a partnership or disregarded entity that directly or indirectly owns such non-amortizable Reference
      Asset), such non-amortizable Reference Asset shall be deemed disposed of at the time of the Change of Control; and

   

  (vi)          if, at the Early Termination Date, there are Units that have not been
      transferred in an Exchange, then all Units shall be deemed
      to be transferred pursuant to the Redemption Right effective on the Early Termination Date.

      DETERMINATION OF CERTAIN REALIZED TAX BENEFITS

   

  Section
      2.1            Exchange
        Schedules. Within ninety (90) calendar days after the filing of the Corporate Taxpayer Return for each Taxable Year in which
      any Exchange has been effected by a TRA Holder, the Corporate Taxpayer shall deliver to each TRA Holder a schedule (the “Exchange
        Schedule”) that shows, in reasonable detail necessary to perform the calculations required by this Agreement, including
      with respect to each TRA Holder participating in any Exchange during such Taxable Year, (i) the Basis Adjustments with respect
      to the Reference Assets as a result of the Exchanges effected by such TRA Holder in such Taxable Year, (ii) the period (or periods)
      over which such Basis Adjustments are amortizable and/or depreciable, and (iii) the portion of any Tax Benefit Payment with respect
      to such TRA Holder that the Corporate Taxpayer intends to treat as Imputed Interest.

   

  Section
      2.2            Tax
        Benefit Payment Schedules.

   

  (a)          Within ninety (90) calendar days after the filing
      of the Corporate Taxpayer Return for any Taxable Year in which there is a Realized Tax Benefit or Realized Tax Detriment, the
      Corporate Taxpayer shall provide to each TRA Holder: (i) a schedule showing, in reasonable detail, (A) the calculation of the
      Realized Tax Benefit or Realized Tax Detriment for such Taxable Year, (B) the portion of the Net Tax Benefit, if any, that is
      Attributable to such TRA Holder who has participated in any Exchange, and (C) the Tax Benefit Payment due, if any, to such TRA
      Holder (a “Tax Benefit Payment Schedule”), (ii) a reasonably detailed calculation by the Corporate Taxpayer
      of the Hypothetical Tax Liability, (iii) a reasonably detailed calculation by the Corporate Taxpayer of the Actual Tax Liability,
      (iv) a copy of the Corporate Taxpayer Return for such Taxable Year, and (v) any other work papers reasonably requested by such
      TRA Holder. The Tax Benefit Payment Schedule will become final as provided in Section 2.3(a) and may be amended as provided
      in Section 2.3(b) (subject to the procedures set forth in Section 2.3(b)).

   

  (b)          For purposes of calculating the Realized Tax
      Benefit or Realized Tax Detriment for any Taxable Year, carryovers or carrybacks of any U.S. federal income Tax item attributable
      to the Basis Adjustments, any Imputed Interest, and any Post-IPO TRA Benefits shall be considered to be subject to the rules of
      the Code and the Treasury Regulations, as applicable, governing the use, limitation and expiration of carryovers or carrybacks
      of the relevant type. If a carryover or carryback of any U.S. federal income Tax item includes a portion that is attributable
      to the Basis Adjustment, any Imputed Interest, or any Post-IPO TRA Benefits and another portion that is not so attributable, such
      respective portions shall be considered to be used in accordance with the “with and without” methodology. The parties
      agree that (i) any payment under this Agreement (to the extent permitted by law) will be treated as a subsequent upward adjustment
      to the purchase price of the relevant Units and will have the effect of creating additional Basis Adjustments to Reference Assets
      for the Corporate Taxpayer in the year of payment, and (ii) as a result, such additional Basis Adjustments will be incorporated
      into the current year calculation and into future year calculations, as appropriate.

  Section
      2.3            Procedure;
        Amendments.

   

  (a)          An applicable Schedule or amendment thereto shall
      become final and binding on all parties thirty (30) calendar days from the first date on which each TRA Holder has received the
      applicable Schedule or amendment thereto unless (i) the TRA Party Representative provides the Corporate Taxpayer with notice of
      a material objection to such Schedule (“Objection Notice”) made in good faith or (ii) the TRA Party Representative
      provides a written waiver of such right of any Objection Notice within the period described in clause (i) above, in which case
      such Schedule or amendment thereto becomes binding on the date waivers from the TRA Party Representative has been received by
      the Corporate Taxpayer. If the Corporate Taxpayer and the TRA Party Representative, for any reason, are unable to successfully
      resolve the issues raised in an Objection Notice within thirty (30) calendar days after receipt by the Corporate Taxpayer of such
      Objection Notice, the Corporate Taxpayer and the TRA Party Representative, on behalf of the TRA Holders, shall employ the Reconciliation
      Procedures under Section 7.10 or Resolution of Disputes procedures under Section 7.9, as applicable.

   

  (b)          The applicable Schedule for any Taxable Year
      may be amended from time to time by the Corporate Taxpayer (i) in connection with a Determination affecting such Schedule, (ii)
      to correct inaccuracies in the Schedule identified as a result of the receipt of additional factual information relating to a
      Taxable Year after the date the Schedule was provided to the TRA Holders, (iii) to comply with the Expert’s determination
      under the Reconciliation Procedures, (iv) to reflect a change in the Realized Tax Benefit or Realized Tax Detriment for such Taxable
      Year attributable to a carryback or carryforward of a loss or other Tax item to such Taxable Year, (v) to reflect a change in
      the Realized Tax Benefit or Realized Tax Detriment for such Taxable Year attributable to an amended Corporate Taxpayer Return
      filed for such Taxable Year or (vi) to adjust an Exchange Schedule to take into account payments made pursuant to this Agreement
      (any such Schedule, an “Amended Schedule”). The Corporate Taxpayer shall provide an Amended Schedule to the
      TRA Holders within sixty (60) calendar days of the occurrence of an event referenced in clauses (i) through (vi) of the preceding
      sentence. For the avoidance of doubt, in the event a Schedule is amended after such Schedule becomes final pursuant to Section
        2.3(a), the Amended Schedule shall not be taken into account in calculating any Tax Benefit Payment in the Taxable Year to
      which the amendment relates but instead shall be taken into account in calculating the Cumulative Net Realized Tax Benefit for
      the Taxable Year in which the amendment actually occurs.

   

  Section
      2.4            Section
        754 Election. In its capacity as the sole managing member of Solaris LLC, the Corporate Taxpayer will ensure that, on and
      after the date hereof and continuing throughout the term of this Agreement, Solaris LLC and any of its eligible Subsidiaries will
      have in effect an election pursuant to Section 754 of the Code (and under any similar provisions of applicable U.S. state or local
      law).

  Article
      III 

      TAX BENEFIT PAYMENTS

   

  Section
      3.1            Payments.

   

  (a)          Within fifteen (15) Business Days after a Tax
      Benefit Payment Schedule delivered to the TRA Holders becomes final in accordance with Section 2.3(a), the Corporate Taxpayer
      shall pay to each TRA Holder the Tax Benefit Payment in respect of such TRA Holder determined pursuant to Section 3.1(b)
      for such Taxable Year. Each such payment shall be made by check, by wire transfer of immediately available funds to the bank account
      previously designated by such TRA Holder to the Corporate Taxpayer, or as otherwise agreed by the Corporate Taxpayer and such
      TRA Holder. For the avoidance of doubt, no Tax Benefit Payment shall be made in respect of estimated Tax payments, including,
      without limitation, U.S. federal or state estimated income Tax payments.

   

  (b)          A “Tax Benefit Payment” in
      respect of a TRA Holder for a Taxable Year means an amount, not less than zero, equal to the sum of the portion of the Net Tax
      Benefit Attributable to such TRA Holder. A Net Tax Benefit is “Attributable” to a TRA Holder to the extent
      that it is derived from any Basis Adjustment that is attributable to the Units acquired or deemed acquired by the Corporate Taxpayer
      or an Exchange undertaken by or with respect to such TRA Holder and any Imputed Interest. Subject to Section 3.3, the “Net
        Tax Benefit” for a Taxable Year shall be an amount equal to the excess, if any, of 85% of the Cumulative Net Realized
      Tax Benefit as of the end of such Taxable Year over the sum of (i) the total amount of payments previously made under this Section
        3.1 and (ii) the total amount of tax benefit payments previously made under the corresponding provision of any Post-IPO TRA;
      provided, for the avoidance of doubt, that no TRA Holder shall be required to return any portion of any previously made
      Tax Benefit Payment.

   

  (c)          If a TRA Holder elects for the provisions of
      this Section 3.1(c) to apply to an Exchange, by notifying the Corporate Taxpayer in writing on or before the due date for
      providing the Exchange Notice with respect to such Exchange (or, with respect to an Exchange in connection with the IPO, on or
      before the IPO Date), the aggregate Tax Benefit Payments to be made to such TRA Holder with respect to such Exchange shall be
      limited to (i) 50%, or such other percentage such TRA Holder elects to apply by notifying the Corporate Taxpayer in writing on
      or before the due date for providing the Exchange Notice with respect to such Exchange (or, with respect to an Exchange in connection
      with the IPO, on or before the IPO Date), of (ii) the amount equal to the sum of (A) any cash, excluding any Tax Benefit Payments,
      received by such TRA Holder in such Exchange and (B) the aggregate Market Value of the Class A Shares received by such TRA Holder
      in such Exchange. Notwithstanding any other provision of this Agreement, this Section 3.1(c) shall not apply to a TRA Holder
      unless such TRA Holder elects for the provisions of this Section 3.1(c) to apply, as provided herein.

   

  Section
      3.2            No
        Duplicative Payments. It is intended that the provisions of this Agreement will not result in duplicative payment of any amount
      (including interest) required under the Tax Receivable Agreements. It is also intended that the provisions of the Tax Receivable
      Agreements will result in 85% of the Cumulative Net Realized Tax Benefit being paid to the Persons to whom payments are due pursuant
      to the Tax Receivable Agreements. The provisions of this Agreement shall be construed in the appropriate manner to achieve these
      fundamental results.

  Section
      3.3            Pro
        Rata Payments; Coordination of Benefits with Other Tax Receivable Agreements.

   

  (a)          Notwithstanding anything in Section 3.1
      to the contrary, to the extent that the aggregate amount of the Corporate Taxpayer’s tax benefit subject to the Tax Receivable
      Agreements is limited in a particular Taxable Year because the Corporate Taxpayer does not have sufficient taxable income to fully
      utilize available deductions and other attributes, the limitation on the tax benefit for the Corporate Taxpayer shall be allocated
      as follows: (i) first among any Post-IPO TRAs (and among all Persons eligible for payments thereunder in the manner set forth
      in such Post-IPO TRAs) and (ii) to the extent of any remaining limitation on tax benefit for the Corporate Taxpayer after the
      application of clause (i), to this Agreement (and among all Persons eligible for payments hereunder). For the avoidance of doubt,
      for purposes of this Section 3.3(a), it is intended that in calculating the Corporate Taxpayer’s tax benefit subject
      to the Tax Receivable Agreements, any available taxable income of the Corporate Taxpayer be first allocated to this Agreement
      and any remaining available taxable income will then be allocated to any Post-IPO TRA.

   

  (b)          After taking into account Section 3.3(a),
      if for any reason the Corporate Taxpayer does not fully satisfy its payment obligations to make all Tax Benefit Payments due under
      the Tax Receivable Agreements in respect of a particular Taxable Year, then, (i) the Corporate Taxpayer will pay the same proportion
      of each Tax Benefit Payment due to each Person to whom a payment is due under each of the Tax Receivable Agreements in respect
      of such Taxable Year, without favoring one obligation over the other, and (ii) no Tax Benefit Payment shall be made in respect
      of any Taxable Year until all Tax Benefit Payments in respect of prior Taxable Years have been made in full.

   

  (c)          To the extent the Corporate Taxpayer makes a
      payment to a TRA Holder in respect of a particular Taxable Year under Section 3.1(a) of this Agreement (taking into account
      Section 3.3(a) and Section 3.3(b)) in an amount in excess of the amount of such payment that should have been made
      to such TRA Holder in respect of such Taxable Year, then (i) such TRA Holder shall not receive further payments under Section
        3.1(a) until such TRA Holder has foregone an amount of payments equal to such excess and (ii) the Corporate Taxpayer will
      pay the amount of such TRA Holder’s foregone payments to the other Persons to whom a payment is due under the Tax Receivable
      Agreements in a manner such that each such Person to whom a payment is due under the Tax Receivable Agreements, to the maximum
      extent possible, receives aggregate payments under Section 3.1(a) or the comparable section of the other Tax Receivable
      Agreement(s), as applicable (in each case, taking into account Section 3.3(a) and Section 3.3(b) or the comparable
      section of the other Tax Receivable Agreement(s) in the amount it would have received if there had been no excess payment to such
      TRA Holder.

   

  

  
    15 

    
      

    

  

   

  (d)          The parties hereto agree that the parties to
      any Post-IPO TRA are expressly made third party beneficiaries of the provisions of this Section 3.3.

   

  (e)          A Post-IPO TRA shall be included in the definition
      of Tax Receivable Agreements for purposes of this Section 3.3 only if such Post-IPO TRA does not provide otherwise.

   

  Article
      IV 

      TERMINATION

   

  Section
      4.1            Early
        Termination at Election of the Corporate Taxpayer. The Corporate Taxpayer may terminate this Agreement at any time by paying
      to each TRA Holder the Early Termination Payment due to such TRA Holder pursuant to Section 4.5(b) (such termination, an
      “Early Termination”); provided that the Corporate Taxpayer may withdraw any notice of exercise of its
      termination rights under this Section 4.1 prior to the time at which any Early Termination Payment has been paid. Upon
      payment of the Early Termination Payments by the Corporate Taxpayer, neither the TRA Holders nor the Corporate Taxpayer shall
      have any further payment obligations under this Agreement, other than for any Tax Benefit Payment previously due and payable but
      unpaid as of the Early Termination Notice and, except to the extent included in the Early Termination Payment, any Tax Benefit
      Payment due for any Taxable Year ending prior to, with or including the Early Termination Date. Upon payment of all amounts provided
      for in this Section 4.1, this Agreement shall terminate.

   

  Section
      4.2            Early
        Termination upon Change of Control. In the event of a Change of Control, all obligations hereunder shall be accelerated and
      such obligations shall be calculated as if an Early Termination Notice had been delivered on the closing date of the Change of
      Control and shall include, but not be limited to the following: (a) payment of the Early Termination Payment calculated as if
      an Early Termination Notice had been delivered on the effective date of a Change of Control, (b) payment of any Tax Benefit Payment
      in respect of a TRA Holder agreed to by the Corporate Taxpayer and such TRA Holder as due and payable but unpaid as of the Early
      Termination Notice, and (c) except to the extent included in the Early Termination Payment, payment of any Tax Benefit Payment
      due for any Taxable Year ending prior to, with or including the effective date of a Change of Control. In the event of a Change
      of Control, the Early Termination Payment shall be calculated utilizing the Valuation Assumptions and by substituting in each
      case the terms “the closing date of a Change of Control” for an “Early Termination Date.”

   

  Section
      4.3            Breach
        of Agreement.

   

  (a)          In the event that the Corporate Taxpayer breaches
      any of its material obligations under this Agreement, whether as a result of failure to make any payment within three (3) months
      of the date when due, as a result of failure to honor any other material obligation required hereunder or by operation of law
      as a result of the rejection of this Agreement in a case commenced under the Bankruptcy Code or otherwise, then if the Majority
      TRA Holders so elect, such breach shall be treated as an Early Termination. Upon such election, all obligations hereunder shall
      be accelerated and such obligations shall be calculated as if an Early Termination Notice had been delivered on the date of such
      breach and shall include, but shall not be limited to, (i) the Early Termination Payment calculated as if an Early Termination
      Notice had been delivered on the date of a breach, (ii) any Tax Benefit Payment previously due and payable but unpaid as of the
      date of the breach, and (iii) except to the extent included in the Early Termination Payment, any Tax Benefit Payment due for
      any Taxable Year ending prior to, with or including the Early Termination Date. Notwithstanding the foregoing, in the event that
      the Corporate Taxpayer breaches this Agreement, if the Majority TRA Holders do not elect to treat such breach as an Early Termination
      pursuant to this Section 4.3(a), the TRA Holders shall be entitled to seek specific performance of the terms hereof.

   

  

  
    16 

    
      

    

  

   

  (b)          The parties agree that the failure of the Corporate
      Taxpayer to make any payment due pursuant to this Agreement within three (3) months of the date such payment is due shall be deemed
      to be a breach of a material obligation under this Agreement for all purposes of this Agreement, and that it shall not be considered
      to be a breach of a material obligation under this Agreement to make a payment due pursuant to this Agreement within three (3)
      months of the date such payment is due. Notwithstanding anything in this Agreement to the contrary, except in the case of an Early
      Termination Payment or any payment treated as an Early Termination Payment, it shall not be a breach of this Agreement if the
      Corporate Taxpayer fails to make any Tax Benefit Payment when due to the extent that the Corporate Taxpayer has insufficient funds
      to make such payment; provided that the interest provisions of Section 5.2 shall apply to such late payment unless
      the Corporate Taxpayer does not have sufficient cash to make such payment as a result of limitations imposed by any existing credit
      agreement to which Solaris LLC or any subsidiary of Solaris LLC is a party, in which case Section 5.2 shall apply, but
      the Default Rate shall be replaced by the Agreed Rate; and provided further that it shall be a breach of this Agreement,
      and the provisions of Section 4.3(a) shall apply as of the original due date of the Tax Benefit Payment, if the Corporate
      Taxpayer makes any distribution of cash or other property to its stockholders while any Tax Benefit Payment is due and payable
      but unpaid.

   

  Section
      4.4            Early
        Termination Notice. If the Corporate Taxpayer chooses to exercise its right of early termination under Section 4.1
      above, the Corporate Taxpayer shall deliver to the TRA Holders notice of such intention to exercise such right (the “Early
        Termination Notice”). Upon delivery of the Early Termination Notice or the occurrence of an event described in Section
        4.2 or Section 4.3(a), the Corporate Taxpayer shall deliver (i) a schedule showing in reasonable detail the calculation
      of the Early Termination Payment (the “Early Termination Schedule”) and (ii) any other work papers reasonably
      requested by the TRA Holders. The Early Termination Schedule shall become final and binding on all parties thirty (30) calendar
      days from the first date on which the TRA Holders have received such Schedule or amendment thereto unless (x) the TRA Party Representative
      provides the Corporate Taxpayer with notice of a material objection to such Schedule made in good faith (“Material Objection
        Notice”) or (y) the TRA Party Representative, on behalf of the TRA Holders, provides a written waiver of such right
      of a Material Objection Notice within the period described in clause (x) above, in which case such Schedule becomes binding on
      the date waivers from the TRA Holders have been received by the Corporate Taxpayer (the “Early Termination Effective
        Date”). If the Corporate Taxpayer and the TRA Party Representative, for any reason, are unable to successfully resolve
      the issues raised in such notice within thirty (30) calendar days after receipt by the Corporate Taxpayer of the Material Objection
      Notice, the Corporate Taxpayer and the TRA Party Representative, on behalf of the TRA Holders, shall employ the Reconciliation
      Procedures under Section 7.10 or Resolution of Disputes procedures under Section 7.9, as applicable.

   

  

  
    17 

    
      

    

  

   

  Section
      4.5            Payment
        upon Early Termination.

   

  (a)          Subject to its right to withdraw any notice of
      Early Termination pursuant to Section 4.1, within three (3) calendar days after the Early Termination Effective Date, the
      Corporate Taxpayer shall pay to each TRA Holder its Early Termination Payment. Each such payment shall be made by check, by wire
      transfer of immediately available funds to a bank account or accounts designated by such TRA Holder, or as otherwise agreed by
      the Corporate Taxpayer and such TRA Holder.

   

  (b)          A TRA Holder’s “Early Termination
        Payment” as of the Early Termination Date shall equal the present value, discounted at the Early Termination Rate as
      of the Early Termination Effective Date, of all Tax Benefit Payments that would be required to be paid by the Corporate Taxpayer
      to such TRA Holder beginning from the Early Termination Date and assuming that the Valuation Assumptions are applied.

      SUBORDINATION AND LATE PAYMENTS

   

  Section
      5.1            Subordination.
      Notwithstanding any other provision of this Agreement to the contrary, any Tax Benefit Payment, Early Termination Payment or any
      payment pursuant to Section 4.2 resulting from a Change of Control or any payment pursuant to Section 5.2 shall rank subordinate
      and junior in right of payment to any principal, interest or other amounts due and payable in respect of any obligations in respect
      of indebtedness for borrowed money of the Corporate Taxpayer and its Subsidiaries (such obligations, “Senior Obligations”)
      and shall rank pari passu with all current or future unsecured obligations of the Corporate Taxpayer that are not Senior Obligations.
      For the avoidance of doubt, notwithstanding the above, the determination of whether it is a breach of this Agreement if the Corporate
      Taxpayer fails to make any Tax Benefit Payment when due is governed by Section 4.3. To the extent that any payment under
      this Agreement is not permitted to be made at the time payment is due as a result of this Section 5.1 and the terms of
      the agreements governing Senior Obligations, such payment obligation nevertheless shall accrue for the benefit of the TRA Holders
      and the Corporate Taxpayer shall make such payments at the first opportunity that such payments are permitted to be made in accordance
      with the terms of the Senior Obligations.

   

  Section
      5.2            Late
        Payments by the Corporate Taxpayer. The amount of all or any portion of any Tax Benefit Payment, Early Termination Payment
      or any other payment under this Agreement not made to any TRA Holder when due under the terms of this Agreement, whether as a
      result of Section 5.1 and the terms of the Senior Obligations or otherwise, shall be payable together with any interest
      thereon, computed at the Default Rate (or, if so provided in Section 4.3(b), at the Agreed Rate) and commencing from the
      date on which such Tax Benefit Payment, Early Termination Payment or any other payment under this Agreement was due and payable.

  Section
      6.1            Participation
        in the Corporate Taxpayer’s and Solaris LLC’s Tax Matters. Except as otherwise provided herein or in the Solaris
      LLC Agreement, the Corporate Taxpayer shall have full responsibility for, and sole discretion over, all Tax matters concerning
      the Corporate Taxpayer and Solaris LLC, including without limitation preparing, filing or amending any Tax Return and defending,
      contesting or settling any issue pertaining to Taxes. Notwithstanding the foregoing, in the event a Taxing Authority initiates
      any audit, examination, or any other administrative or judicial proceeding (a “Tax Proceeding”) of the Corporate
      Taxpayer or Solaris LLC any portion of the outcome of which is reasonably expected to affect the rights and obligations of the
      TRA Holders under this Agreement and the TRA Holders elect a TRA Party Representative, then the Corporate Taxpayer (i) shall notify
      the TRA Party Representative of, and keep the TRA Party Representative reasonably informed with respect to, the relevant portion
      of such Tax Proceeding (ii) shall provide the TRA Party Representative with reasonable opportunity to provide information and
      other input to the Corporate Taxpayer, Solaris LLC and their respective advisors concerning the conduct of any such portion of
      a Tax Proceeding; provided further, that the Corporate Taxpayer and Solaris LLC shall not be required to take any action,
      or refrain from taking any action, that is inconsistent with any provision of the Solaris LLC Agreement.

   

  Section
      6.2            Consistency.
      Unless there is a Determination to the contrary, the Corporate Taxpayer and each of the TRA Holders agree to report, and to cause
      their respective Subsidiaries to report, for all purposes, including U.S. federal, state and local Tax purposes and financial
      reporting purposes, all Tax-related items (including, without limitation, the Basis Adjustments, Imputed Interest, and each Tax
      Benefit Payment), but, for financial reporting purposes, only in respect of items that are not explicitly characterized as “deemed”
      or in a similar manner by the terms of this Agreement, in a manner consistent with the description of any Tax characterization
      herein (including as set forth in Section 2.2(b) and Section 3.1(b) and any Schedule required to be provided by
      or on behalf of the Corporate Taxpayer under this Agreement, as finally determined pursuant to Section 2.3. If the Corporate
      Taxpayer and any TRA Holder, for any reason, are unable to successfully resolve any disagreement concerning such treatment within
      thirty (30) calendar days, the Corporate Taxpayer and such TRA Holder shall employ the Reconciliation Procedures under Section
        7.10 or Resolution of Disputes procedures under Section 7.9, as applicable.

   

  Section
      6.3            Cooperation.
      Each TRA Holder shall (i) furnish to the Corporate Taxpayer in a timely manner such information, documents and other materials
      as the Corporate Taxpayer may reasonably request for purposes of making any determination or computation necessary or appropriate
      under this Agreement, preparing any Tax Return or contesting or defending any Tax Proceeding, (ii) make itself available to the
      Corporate Taxpayer and its representatives to provide explanations of documents and materials and such other information as the
      Corporate Taxpayer or its representatives may reasonably request in connection with any of the matters described in clause (i)
      above, and (iii) reasonably cooperate in connection with any such matter. The Corporate Taxpayer shall reimburse each TRA Holder
      for any reasonable third-party costs and expenses incurred pursuant to this Section 6.3.

  Section
      7.4            Governing
        Law. This Agreement and the rights and obligations of the parties hereunder shall be governed by, and construed in accordance
      with, the law of the State of Delaware, without regard to the conflicts of laws principles thereof that would mandate the application
      of the laws of another jurisdiction.

   

  Section
      7.5            Severability.
      If any term or other provision of this Agreement is invalid, illegal or incapable of being enforced by any law or public policy,
      all other terms and provisions of this Agreement shall nevertheless remain in full force and effect so long as the economic or
      legal substance of the transactions contemplated hereby is not affected in any manner materially adverse to any party. Upon such
      determination that any term or other provision is invalid, illegal or incapable of being enforced, the parties hereto 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 in order that the transactions contemplated hereby are consummated as originally contemplated to the greatest extent possible.

   

  Section
      7.6            Successors;
        Assignment.

   

  (a)          No TRA Holder may assign this Agreement to any
      Person without the prior written consent of the Corporate Taxpayer; provided, however, that:

   

  (i)            to the extent Units are transferred in accordance
      with the terms of the Solaris LLC Agreement, the transferring TRA Holder shall have the option to assign to the transferee of
      such Units the transferring TRA Holder’s rights under this Agreement with respect to such transferred Units as long as (A)
      such transferee has executed and delivered, or, in connection with such transfer, executes and delivers, a Joinder, agreeing to
      become a “TRA Holder” for all purposes of this Agreement, and (B) the assigning party represents to the Corporate
      Taxpayer that such assignment will be made in accordance with all applicable securities laws, and

   

  (ii)           the right to receive any and all payments payable
      or that may become payable to a TRA Holder pursuant to this Agreement that, once an Exchange has occurred, arise with respect
      to the Units transferred in such Exchange, may be assigned to any Person or Persons as long as (A) any such Person has executed
      and delivered, or, in connection with such assignment, executes and delivers, a Joinder, agreeing to be bound by Section 7.13
      and acknowledging specifically the terms of Section 7.6(b), and (B) the assigning party represents to the Corporate
      Taxpayer that such assignment will be made in accordance with all applicable securities laws.

   

  For
      the avoidance of doubt, if a TRA Holder transfers Units but does not assign to the transferee of such Units the rights of such
      TRA Holder under this Agreement with respect to such transferred Units, such TRA Holder shall continue to be entitled to receive
      the Tax Benefit Payments, if any, due hereunder with respect to, including any Tax Benefit Payments arising in respect of a subsequent
      Exchange of, such Units.

   

  (b)         
      Notwithstanding the foregoing provisions of this Section 7.6, no assignee described in Section 7.6(a)(ii) shall
      have any rights under this Agreement except for the right to enforce its right to receive payments under this
      Agreement.

   

    

  
    21 

    
      

    

  

   

  

  (c)          The Person designated as the TRA Party Representative
      may not be changed without the prior written consent of the Corporate Taxpayer and the Majority TRA Holders.

   

  (d)          Except as otherwise specifically provided herein,
      all of the terms and provisions of this Agreement shall be binding upon, shall inure to the benefit of and shall be enforceable
      by the parties hereto and their respective successors, assigns, heirs, executors, administrators and legal representatives. The
      Corporate Taxpayer shall cause any direct or indirect successor (whether by purchase, merger, consolidation or otherwise) to all
      or substantially all of the business or assets of the Corporate Taxpayer, by written agreement, expressly to assume and agree
      to perform this Agreement in the same manner and to the same extent that the Corporate Taxpayer would be required to perform if
      no such succession had taken place.

   

  Section
      7.7            Amendments;
        Waivers. No provision of this Agreement may be amended unless such amendment is approved in writing by each of the Corporate
      Taxpayer and the Majority TRA Holders; provided, however, that no such amendment shall be effective if such amendment would
      have a disproportionate effect on the payments certain TRA Holders will or may receive under this Agreement unless all such disproportionately
      affected TRA Holders consent in writing to such amendment; and provided, further, that amendment of the definition of Change
      of Control will also require the written approval of a majority of the Independent Directors. No provision of this Agreement may
      be waived unless such waiver is in writing and signed by the party against whom the waiver is to be effective.

   

  Section
      7.8            Titles
        and Subtitles. The titles of the sections and subsections of this Agreement are for convenience of reference only and are
      not to be considered in construing this Agreement.

   

  Section
      7.9            Resolution
        of Disputes.

   

  (a)          Any and all disputes which are not governed by
      Section 7.10, including any ancillary claims of any party, arising out of, relating to or in connection with the validity,
      negotiation, execution, interpretation, performance or non-performance of this Agreement (including the validity, scope and enforceability
      of this Section 7.9 and Section 7.10) (each a “Dispute”) shall be governed by this Section
        7.9. The parties hereto shall attempt in good faith to resolve all Disputes by negotiation. If a Dispute between the parties
      hereto cannot be resolved in such manner, such Dispute shall be finally settled by arbitration conducted by a single arbitrator
      in accordance with the then-existing rules of arbitration of the American Arbitration Association. If the parties to the Dispute
      fail to agree on the selection of an arbitrator within ten (10) calendar days of the receipt of the request for arbitration, the
      American Arbitration Association shall make the appointment. The arbitrator shall be a lawyer admitted to the practice of law
      in a U.S. state, or a nationally recognized expert in the relevant subject matter, and shall conduct the proceedings in the English
      language. Performance under this Agreement shall continue if reasonably possible during any arbitration proceedings. In addition
      to monetary damages, the arbitrator shall be empowered to award equitable relief, including an injunction and specific performance
      of any obligation under this Agreement. The arbitrator is not empowered to award damages in excess of compensatory damages, and
      each party hereby irrevocably waives any right to recover punitive, exemplary or similar damages with respect to any Dispute.
      The award shall be the sole and exclusive remedy between the parties regarding any claims, counterclaims, issues, or accounting
      presented to the arbitral tribunal. Judgment upon any award may be entered and enforced in any court having jurisdiction over
      a party or any of its assets.

   

  

  
    22 

    
      

    

  

   

  (b)          Notwithstanding the provisions of Section
        7.9(a), the Corporate Taxpayer may bring an action or special proceeding in any court of competent jurisdiction for the purpose
      of compelling a party to arbitrate, seeking temporary or preliminary relief in aid of an arbitration hereunder, and/or enforcing
      an arbitration award and, for the purposes of this Section 7.9(b), the TRA Party Representative and each TRA Holder (i)
      expressly consents to the application of Section 7.9(c) to any such action or proceeding, (ii) agrees that proof shall
      not be required that monetary damages for breach of the provisions of this Agreement would be difficult to calculate and that
      remedies at law would be inadequate, and (iii) irrevocably appoints the Corporate Taxpayer as agent of such party for service
      of process in connection with any such action or proceeding and agrees that service of process upon such agent, who shall promptly
      advise such party in writing of any such service of process, shall be deemed in every respect effective service of process upon
      such party in any such action or proceeding.

   

  (c)          EACH PARTY HEREBY IRREVOCABLY SUBMITS TO THE
      JURISDICTION OF ANY FEDERAL COURT OF THE DISTRICT OF DELAWARE OR THE DELAWARE COURT OF CHANCERY FOR THE PURPOSE OF ANY JUDICIAL
      PROCEEDING BROUGHT IN ACCORDANCE WITH THE PROVISIONS OF PARAGRAPH (B) OF THIS SECTION 7.9 OR ANY JUDICIAL PROCEEDING ANCILLARY
      TO AN ARBITRATION OR CONTEMPLATED ARBITRATION ARISING OUT OF OR RELATING TO OR CONCERNING THIS AGREEMENT. Such ancillary judicial
      proceedings include any suit, action or proceeding to compel arbitration, to obtain temporary or preliminary judicial relief in
      aid of arbitration, or to confirm an arbitration award. The parties acknowledge that the fora designated by this Section 7.9(c)
      have a reasonable relation to this Agreement, and to the parties’ relationship with one another.

   

  (d)          The parties hereby waive, to the fullest extent
      permitted by applicable law, any objection which they now or hereafter may have to personal jurisdiction or to the laying of venue
      of any such ancillary suit, action or proceeding brought in any court referred to in Section 7.9(c) and such parties agree
      not to plead or claim the same.

   

  

  
    23 

    
      

    

  

   

  Section
      7.10        Reconciliation.
      In the event that the TRA Party Representative or any TRA Holder (as applicable, the “Disputing Party”) and
      the Corporate Taxpayer are unable to resolve a disagreement with respect to the calculations required to produce the schedules
      described in Section 2.3, Section 4.4 and Section 6.2 (but not, for the avoidance doubt, with respect to
      any legal interpretation with respect to such provisions or schedules) within the relevant period designated in this Agreement
      (“Reconciliation Dispute”), the Reconciliation Dispute shall be submitted for determination to the Expert.
      The Expert shall be a partner or principal in a nationally recognized accounting or law firm, and unless the Corporate Taxpayer
      and the Disputing Party agree otherwise, the Expert shall not, and the firm that employs the Expert shall not, have any material
      relationship with the Corporate Taxpayer or the Disputing Party or other actual or potential conflict of interest. If the parties
      are unable to agree on an Expert within fifteen (15) calendar days of receipt by the respondent(s) of written notice of a Reconciliation
      Dispute, the Expert shall be appointed by the American Arbitration Association. The Expert shall resolve (a) any matter relating
      to the Exchange Schedule or an amendment thereto or the Early Termination Schedule or an amendment thereto within thirty (30)
      calendar days, (b) any matter relating to a Tax Benefit Payment Schedule or an amendment thereto within fifteen (15) calendar
      days , and (c) any matter related to treatment of any tax-related item as contemplated in Section 6.2 within fifteen (15)
      calendar days, or, in each case, as soon thereafter as is reasonably practicable after such matter has been submitted to the Expert
      for resolution. Notwithstanding the preceding sentence, if the matter is not resolved before any payment that is the subject of
      a disagreement would be due (in the absence of such disagreement) or any Tax Return reflecting the subject of a disagreement is
      due, any portion of such payment that is not under dispute shall be paid on the date prescribed by this Agreement and such Tax
      Return may be filed as prepared by the Corporate Taxpayer, subject to adjustment or amendment upon resolution. The costs and expenses
      relating to the engagement of such Expert or amending any Tax Return shall be borne by the Corporate Taxpayer except as provided
      in the next sentence. The Corporate Taxpayer and the Disputing Party shall each bear its own costs and expenses of such proceeding,
      unless (i) the Expert adopts such Disputing Party’s position, in which case the Corporate Taxpayer shall reimburse such
      Disputing Party for any reasonable out-of-pocket costs and expenses in such proceeding, or (ii) the Expert adopts the Corporate
      Taxpayer’s position, in which case such Disputing Party shall reimburse the Corporate Taxpayer for any reasonable out-of-pocket
      costs and expenses in such proceeding. Any dispute as to whether a dispute is a Reconciliation Dispute within the meaning of this
      Section 7.10 shall be decided by the Expert. The Expert shall finally determine any Reconciliation Dispute and the determinations
      of the Expert pursuant to this Section 7.10 shall be binding on the Corporate Taxpayer and its Subsidiaries and the Disputing
      Party and may be entered and enforced in any court having jurisdiction.

   

  Section
      7.11        Withholding.
      The Corporate Taxpayer shall be entitled to deduct and withhold from any payment payable pursuant to this Agreement such amounts
      as the Corporate Taxpayer is required to deduct and withhold with respect to the making of such payment under the Code or any
      provision of U.S. federal, state, local or non-U.S. tax law; provided, that, the Corporate Taxpayer shall use commercially
      reasonable efforts to notify any applicable TRA Holder of its intent to withhold at least ten (10) Business Days prior to withholding
      such amounts. To the extent that amounts are so withheld and paid over to the appropriate Taxing Authority by the Corporate Taxpayer,
      such withheld amounts shall be treated for all purposes of this Agreement as having been paid to the relevant TRA Holder. The
      Corporate Taxpayer shall provide evidence of such payment to the relevant TRA Holder upon such TRA Holder’s written request,
      to the extent that such evidence is available.

   

  Section
      7.12        Admission of the Corporate Taxpayer into a Consolidated Group; Transfers of Corporate
        Assets.

   

  (a)          If the Corporate Taxpayer is or becomes a member
      of a combined, consolidated, affiliated or unitary group that files a consolidated, combined or unitary income Tax Return pursuant
      to Sections 1501 et seq. of the Code or any corresponding provisions of U.S. state or local Tax law, then: (i) the provisions
      of this Agreement shall be applied with respect to the relevant group as a whole; and (ii) Tax Benefit Payments, Early Termination
      Payments and other applicable items hereunder shall be computed with reference to the consolidated (or combined or unitary, where
      applicable) taxable income, gain, loss, deduction and attributes of the relevant group as a whole.

   

  

  
    24 

    
      

    

  

   

  (b)          If the Corporate Taxpayer (or any other entity
      that is obligated to make a Tax Benefit Payment or Early Termination Payment hereunder), Solaris LLC or any of Solaris LLC’s
      direct or indirect Subsidiaries that is treated as a partnership or disregarded entity for U.S. federal income tax purposes (but
      only to the extent such Subsidiaries are not held through any entity treated as a corporation for U.S. federal income tax purposes)
      (a “Transferor”) transfers one or more Reference Assets to a corporation (or a Person classified as a corporation
      for U.S. federal income tax purposes) with which the Transferor does not file a consolidated Tax Return pursuant to Section 1501
      of the Code, the Transferor, for purposes of calculating the amount of any Tax Benefit Payment or Early Termination Payment (e.g.,
      calculating the gross income of the entity and determining the Realized Tax Benefit of such entity) due hereunder, shall be treated
      as having disposed of such Reference Assets in a fully taxable transaction on the date of such contribution. The consideration
      deemed to be received by the Transferor shall be equal to the fair market value of the transferred Reference Assets, plus, without
      duplication, (i) the amount of debt to which any such Reference Asset is subject, in the case of a transfer of an encumbered Reference
      Asset or (ii) the amount of debt allocated to any such Reference Asset, in the case of a contribution of a partnership interest.
      For purposes of this Section 7.12(b), a transfer of a partnership interest shall be treated as a transfer of the Transferor’s
      share of each of the assets and liabilities of that partnership.

   

  Section
      7.13        Confidentiality.

   

  (a)          Each TRA Holder and each of such TRA Holder’s
      assignees acknowledges and agrees that the information of the Corporate Taxpayer is confidential and, except in the course of
      performing any duties as necessary for the Corporate Taxpayer and its Affiliates, as required by law or legal process or to enforce
      the terms of this Agreement, such Person shall keep and retain in the strictest confidence and not disclose to any Person any
      confidential matters, acquired pursuant to this Agreement, of the Corporate Taxpayer and its Affiliates and successors, concerning
      Solaris LLC and its Affiliates and successors or the TRA Holders, learned by any TRA Holder heretofore or hereafter. This Section
        7.13 shall not apply to (i) any information that has been made publicly available by the Corporate Taxpayer or any of its
      Affiliates, becomes public knowledge (except as a result of an act of a TRA Holder in violation of this Agreement) or is generally
      known to the business community and (ii) the disclosure of information (A) as may be proper in the course of performing such TRA
      Holder’s obligations, or monitoring or enforcing such TRA Holder’s rights, under this Agreement, (B) as part of such
      TRA Holder’s normal reporting, rating or review procedure (including normal credit rating and pricing process), or in connection
      with such TRA Holder’s or such TRA Holder’s Affiliates’ normal fund raising, marketing, informational or reporting
      activities, or to such TRA Holder’s (or any of its Affiliates’) Affiliates, auditors, accountants, or attorneys, (C)
      to any bona fide prospective assignee of such TRA Holder’s rights under this Agreement, or prospective merger or other business
      combination partner of such TRA Holder, provided that such assignee or merger partner agrees to be bound by the provisions
      of this Section 7.13, (D) as is required to be disclosed by order of a court of competent jurisdiction, administrative
      body or governmental body, or by subpoena, summons or legal process, or by law, rule or regulation; provided that any TRA
      Holder required to make any such disclosure to the extent legally permissible shall provide the Corporate Taxpayer prompt notice
      of such disclosure, or to regulatory authorities or similar examiners conducting regulatory reviews or examinations (without any
      such notice to the Corporate Taxpayer), or (E) to the extent necessary for a TRA Holder to prepare and file its Tax Returns, to
      respond to any inquiries regarding such Tax Returns from any Taxing Authority or to prosecute or defend any Tax Proceeding with
      respect to such Tax Returns. Notwithstanding anything to the contrary herein, each TRA Holder and each of its assignees (and each
      employee, representative or other agent of such TRA Holder or its assignees, as applicable) may disclose to any and all Persons,
      without limitation of any kind, the Tax treatment and Tax structure of the Corporate Taxpayer, Solaris LLC, the TRA Holders and
      their Affiliates, and any of their transactions, and all materials of any kind (including opinions or other Tax analyses) that
      are provided to any TRA Holder relating to such Tax treatment and Tax structure.

   

  

  
    25 

    
      

    

  

   

  (b)         If a TRA Holder or an assignee commits a breach,
      or threatens to commit a breach, of any of the provisions of this Section 7.13, the Corporate Taxpayer shall have the right
      and remedy to have the provisions of this Section 7.13 specifically enforced by injunctive relief or otherwise by any court
      of competent jurisdiction without the need to post any bond or other security, it being acknowledged and agreed that any such
      breach or threatened breach shall cause irreparable injury to the Corporate Taxpayer or any of its Subsidiaries or the TRA Holders
      and that money damages alone shall not provide an adequate remedy to such Persons. Such rights and remedies shall be in addition
      to, and not in lieu of, any other rights and remedies available at law or in equity.

   

  Section
      7.14        No
        More Favorable Terms. None of the Corporate Taxpayer nor any of its Subsidiaries shall enter into any additional agreement
      providing rights similar to this Agreement to any Person (including any agreement pursuant to which the Corporate Taxpayer is
      obligated to pay amounts with respect to tax benefits resulting from any net operating losses or other tax attributes to which
      the Corporate Taxpayer becomes entitled as a result of a transaction) if such agreement provides terms that are more favorable
      to the counterparty under such agreement than those provided to the TRA Holders under this Agreement; provided, however,
      that the Corporate Taxpayer (or any of its Subsidiaries) may enter into such an agreement if this Agreement is amended to make
      such more favorable terms available to the TRA Holders.

   

  Section
      7.15        Change
        in Law. Notwithstanding anything herein to the contrary, if, in connection with an actual or proposed change in law, a TRA
      Holder reasonably believes that the existence of this Agreement could cause income (other than income arising from receipt of
      a payment under this Agreement) recognized by such TRA Holder upon any Exchange to be treated as ordinary income rather than capital
      gain (or otherwise taxed at ordinary income rates) for U.S. federal income tax purposes or would have other material adverse tax
      consequences to such TRA Holder and/or its direct or indirect owners, then at the election of such TRA Holder and to the extent
      specified by such TRA Holder, this Agreement (i) shall cease to have further effect, (ii) shall not apply to an Exchange by such
      TRA Holder occurring after a date specified by it, or (iii) shall otherwise be amended in a manner determined by such TRA Holder
      to waive any benefits to which such TRA Holder would otherwise be entitled under this Agreement, provided that such amendment
      shall not result in an increase in or acceleration of payments under this Agreement at any time as compared to the amounts and
      times of payments that would have been due in the absence of such amendment.

  Section
      7.16        Independent Nature of TRA Holders’ Rights and Obligations.  The
        rights and obligations of each TRA Holder are independent of the rights and obligations of any other TRA Holder. No TRA Holder
        shall be responsible in any way for the performance of the obligations of any other TRA Holder, nor shall any TRA Holder have
        the right to enforce the rights or obligations of any other TRA Holder. The obligations of each TRA Holder are solely for the
        benefit of, and shall be enforceable solely by, the Corporate Taxpayer. The decision of each TRA Holder to enter into this Agreement
        has been made by such TRA Holder independently of any other TRA Holder. Nothing contained herein or in any other agreement or
        document delivered at any closing (other than the Solaris LLC Agreement), and no action taken by any TRA Holder pursuant hereto
        or thereto, shall be deemed to constitute the TRA Holders as a partnership, an association, a joint venture or any other kind
        of entity, or create a presumption that the TRA Holders are in any way acting in concert or as a group with respect to such rights
        or obligations or the transactions contemplated hereby, and the Corporate Taxpayer acknowledges that the TRA Holders are not acting
        in concert or as a group and will not assert any such claim with respect to such rights or obligations or the transactions contemplated
        hereby.
