ARTICLE II

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 Agent 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 and (ii) the period (or periods) over which such Basis Adjustments are amortizable and/or depreciable.

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 Agent: (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 each TRA Holder who has participated in any Exchange, (C) the Accrued Amount with respect to any such Net Tax Benefit that is Attributable to such TRA Holder, (D) the Tax Benefit Payment due to each such TRA Holder, and (E) the portion of such Tax Benefit Payment that the Corporate Taxpayer intends to treat as Imputed Interest (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 any Agent. In addition, the Corporate Taxpayer shall allow each Agent reasonable access at no cost to the appropriate representatives of the Corporate Taxpayer in connection with a review of such Tax Benefit Payment Schedule. 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, 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, 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 and other than amounts accounted for as Imputed Interest) 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 all Agents have received the applicable Schedule or amendment thereto unless (i) any Agent, within thirty (30) calendar days after receiving an applicable Schedule or amendment thereto, provides the Corporate Taxpayer and each other Agent with notice of a material objection to such Schedule (“Objection Notice”) made in good faith or (ii) each Agent 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 all Agents have been received by the Corporate Taxpayer. If the Corporate Taxpayer and the Agents, 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 Agents 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 Agents, (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 each Agent 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 five (5) Business Days after a Tax Benefit Payment Schedule delivered to the Agents 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 and the Accrued Amount with respect thereto. A Net Tax Benefit is “Attributable” to a TRA Holder to the extent that it is derived from any Basis Adjustment or Imputed Interest that is attributable to the Units acquired or deemed acquired by the Corporate Taxpayer in an Exchange undertaken by or with respect to such TRA Holder. 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 (excluding payments attributable to Accrued Amounts) 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. The “Accrued Amount” with respect to any portion of a Net Tax Benefit Attributable to a TRA Holder shall equal an amount determined in the same manner as interest on such portion of the Net Tax Benefit Attributable to a TRA Holder for a Taxable Year calculated at the Agreed Rate from the due date (without extensions) for filing the Corporate Taxpayer Return for such Taxable Year until the Payment Date. For the avoidance of doubt, for Tax purposes, the Accrued Amount shall not be treated as interest but shall instead be treated as additional consideration for the acquisition of Units in an Exchange unless otherwise required by law.

(c) Notwithstanding any provision of this Agreement to the contrary, unless a TRA Holder elects for the provisions of this Section 3.1(c) not to apply to any 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 any Exchange shall be limited to (i) [ ]%, 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, provided, for the avoidance of doubt, that such amount shall not include any Imputed Interest with respect to such Exchange.

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, and the Accrued Amount thereon, 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), but excluding payments attributable to Accrued Amounts) 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), but excluding payments attributable to Accrued Amounts) in the amount it would have received if there had been no excess payment to such TRA Holder.

(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.

(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 each Agent 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 any Agent. In addition, the Corporate Taxpayer shall allow each Agent reasonable access at no cost to the appropriate representatives of the Corporate Taxpayer in connection with a review of such Early Termination Schedule. The Early Termination Schedule shall become final and binding on all parties thirty (30) calendar days from the first date on which all Agents have received such Schedule or amendment thereto unless (x) any Agent, within thirty (30) calendar days after receiving the Early Termination Schedule, provides the Corporate Taxpayer and each other Agent with notice of a material objection to such Schedule made in good faith (“Material Objection Notice”) or

(y) each Agent 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 all Agents have been received by the Corporate Taxpayer (the “Early Termination Effective Date”). If the Corporate Taxpayer and the Agents, 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 Agents shall employ the Reconciliation Procedures under Section 7.10 or Resolution of Disputes procedures under Section 7.9, as applicable.

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.

ARTICLE V

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.

ARTICLE VI

NO DISPUTES; CONSISTENCY; COOPERATION

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, the Corporate Taxpayer (i) shall notify each Agent of, and keep each Agent reasonably informed with respect to, the portion of any audit, examination, or any other administrative or judicial proceeding (a “Tax Proceeding”) of the Corporate Taxpayer or Solaris LLC by a Taxing Authority the outcome of which is reasonably expected to affect the rights and obligations of the TRA Holders under this Agreement, (ii) shall provide each Agent 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, however, that the Corporate Taxpayer shall not settle or otherwise resolve any part of a Tax Proceeding described in the previous clause that relates to a Basis Adjustment or the deduction of Imputed Interest (and in each case, that is reasonably expected to have a material effect on the TRA Holders’ rights under this Agreement) without the consent of the relevant Agent, which consent shall not be unreasonably withheld, conditioned or delayed; 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 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 7.3 Entire Agreement; No Third Party Beneficiaries. This Agreement constitutes the entire agreement and supersedes all prior agreements and understandings, both written and oral, among the parties with respect to the subject matter hereof. This Agreement shall be binding upon and inure solely to the benefit of each party hereto and their respective successors and permitted assigns, and nothing in this Agreement, express or implied, is intended to or shall confer upon any other Person any right, benefit or remedy of any nature whatsoever under or by reason of this Agreement, except as expressly provided in Section 3.3.

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 such transferee has executed and delivered, or, in connection with such transfer, executes and delivers, a joinder to this Agreement, in form and substance reasonably satisfactory to the Corporate Taxpayer, agreeing to become a “TRA Holder” for all purposes of this Agreement, 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 any such Person has executed and delivered, or, in connection with such assignment, executes and delivers, a joinder to this Agreement, in form and substance reasonably satisfactory to the Corporate Taxpayer, agreeing to be bound by Section 7.13 and acknowledging specifically the terms of Section 7.6(b).

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. Notwithstanding the foregoing provisions of this Section 7.6(a), Yorktown X may assign this Agreement to the Persons that are partners in Yorktown X as of the date of this Agreement, and each such Person may assign this Agreement to any of such Person’s Affiliates, without the prior written consent of the Corporate Taxpayer, provided that in either case (i) each such transferee executes and delivers a joinder to this Agreement, in form and substance reasonably satisfactory to the Corporate Taxpayer, agreeing to become a “TRA Holder” for all purposes of this Agreement, and (ii) each transferor provides the Corporate Taxpayer prior to any such transfer a written opinion of counsel, which counsel shall be satisfactory to the Corporate Taxpayer, that the transfer of this Agreement complies with all applicable securities laws.

(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.

(c) The Person designated as the Agent other than the Yorktown Agent may not be changed without the prior written consent of the Corporate Taxpayer and the Majority TRA Holders (for this purpose, calculated by excluding Yorktown X, any Affiliates of Yorktown X, and each of their assignees).

(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.

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.

(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), each Agent 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.

Section 7.10 Reconciliation. In the event that any Agent 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.

(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 Agent and each of its assignees and 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 Agent or 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 an Agent or 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, attorneys or other agents, (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 Agent (and each employee, representative or other agent of such Agent or its assignees, as applicable) and 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 Agents, 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 the Agents or any TRA Holder relating to such Tax treatment and Tax structure.

(b) If an Agent or an assignee or 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.
