over which each Exchange Basis Adjustment is amortizable and/or depreciable. For the avoidance of doubt, payments made under this Agreement shall not be treated as resulting in an Exchange Basis Adjustment to the extent such payments are treated as
Imputed Interest. 
 Section 2.2 Tax Benefit Schedule. Within sixty (60) calendar days after the filing of the U.S. federal
income Tax Return of the Corporate Taxpayer for any Taxable Year in which there is a Realized Tax Benefit or Realized Tax Detriment, the Corporate Taxpayer shall provide to Agent: (i) a schedule showing, in reasonable detail, the calculation of

 Section 2.3 Procedure;
Amendments. 
 (a) Procedure. An applicable Schedule or amendment thereto shall become final and binding on all parties thirty
(30) calendar days from the first date on which Agent has received the applicable Schedule or amendment thereto unless Agent (i) within thirty (30) calendar days after receiving an applicable Schedule or amendment thereto, provides
the Corporate Taxpayer with notice of a material objection to such Schedule (“Objection Notice”) made in good faith or (ii) 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 the waiver is received by the Corporate Taxpayer. If the parties, 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 Agent shall employ the reconciliation procedures described in Section 7.9 of this Agreement (the

 (b) Amended Schedule. 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 material 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 Agent, (iii) to comply with the Expert’s determination under the Reconciliation Procedures, (iv) to reflect a material change in the Realized Tax Benefit or
Realized Tax Detriment for such Taxable Year attributable to a carryback or carryforward of a 

  
 10 








 
loss or other Tax item to such Taxable Year, (v) to reflect a material change in the Realized Tax Benefit or Realized Tax Detriment for such Taxable Year attributable to an amended Tax
Return filed for such Taxable Year or (vi) to adjust an Exchange Basis Schedule to take into account payments made pursuant to this Agreement (any such Schedule, an “Amended Schedule”). 

ARTICLE III 
 TAX
BENEFIT PAYMENTS 
 Section 3.1 Payments. 

(a) Payments. Subject to Section 3.5, within five (5) calendar days after a Tax Benefit Schedule delivered to Agent
becomes final in accordance with Section 2.3(a), the Corporate Taxpayer shall pay to each TRA Holder its proportionate share of the Tax Benefit Payment determined pursuant to Section 3.1(b) for such Taxable Year. Each such
payment shall be made by wire transfer of immediately available funds to the bank account previously designated by the TRA Holder to the Corporate Taxpayer or as otherwise agreed by the Corporate Taxpayer and the 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 estimated income Tax payments. Notwithstanding the foregoing, the Corporate Taxpayer shall have no obligation to make a Tax
Benefit Payment with respect to a Taxable Year prior to December 19 of the subsequent calendar year. 
 (b) A “Tax Benefit
Payment” means the sum of the Net Tax Benefit and the Accrued Amount. 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 total amount of payments previously made under this Section 3.1 (excluding payments attributable to Accrued Amounts); provided, for the avoidance of doubt, that a
TRA Holder shall not be required to return any portion of any previously made Tax Benefit Payment. The “Accrued Amount” shall equal the interest on the Net Tax Benefit calculated at the Agreed Rate from the due date (without
extensions) for filing the Corporate Taxpayer Return with respect to Taxes 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 Spark HoldCo Units in an Exchange unless otherwise required by law. 
 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 this Agreement. It is also intended that the provisions of this Agreement
will result in 85% of the Cumulative Net Realized Tax Benefit, and the Accrued Amount thereon, being paid to the TRA Holders pursuant to this Agreement. The provisions of this Agreement shall be construed in the appropriate manner to achieve these
fundamental results. 
 Section 3.3 Proportionate Share and Pro Rata Payments. 

(a) Proportionate Share. For purposes of this Agreement, a TRA Holder’s “proportionate share” for any Taxable Year equals
(i) the deductions available for use in such Taxable Year associated with the Exchange Basis Adjustments and the Imputed Interest attributable to such TRA Holder, divided by (ii) the deductions associated with all Exchange Basis
Adjustments and all Imputed Interest that are available for use in such Taxable Year. 

  
 11 








 (b) Pro Rata Payments. If the Corporate Taxpayer lacks sufficient funds to satisfy or is
prevented under any credit agreement or other arrangement from satisfying its obligations to make all Tax Benefit Payments due in a particular Taxable Year, each TRA Holder shall receive its proportionate share of the total funds available in the
Taxable Year to make the Tax Benefit Payments. 
 Section 3.4 Opt Out. 

(a) Notwithstanding Section 3.1, prior to an Exchange, a TRA Holder may elect not to receive any payments under this Agreement with
respect to such Exchange, by delivering written notice evidencing such election (an “Opt Out Notice”) to the Corporate Taxpayer at least three Business Days prior to the Exchange Date of the relevant Exchange. An Opt Out Notice,
when delivered, shall be irrevocable. 
 (b) This Agreement shall not apply to any Exchange which is covered by an Opt Out Notice delivered
pursuant to Section 3.4(a), and all computations hereunder, including the computation of any Tax Benefit Payments and determination of any amounts attributable to a TRA Holder, shall be made without taking into account Exchanges covered
by such Opt Out Notice. For the avoidance of doubt, a TRA Holder who makes an election pursuant to Section 3.4(a) shall remain entitled to payments under this Agreement with respect to any Exchanges for which no election has been made
pursuant to Section 3.4(a). 
 Section 3.5 Five-Year Deferral Period. 

(a) Any Tax Benefit Payment that would otherwise be due and payable pursuant to Section 3.1(a) during the Five-Year Deferral Period
shall be reduced to the extent necessary to cause the TRA Coverage Ratio with respect to such Tax Benefit Payment to be met. The “TRA Coverage Ratio” shall be met with respect to a Tax Benefit Payment if Cash Available for
Distribution during the four-quarter period ending on September 30 of the calendar year in which such Tax Benefit Payment would be due and payable equals or exceeds 130% of the Total Distributions for such four-quarter period. The cumulative
amount by which any Tax Benefit Payments are reduced pursuant this Section 3.5(a) is referred to herein as the “Deferred TRA Amount.” For the avoidance of doubt, in the event that the TRA Coverage Ratio is met with
respect to any portion of a Tax Benefit Payment, that portion of the Tax Benefit Payment shall be due and payable under Section 3.1(a), with the remainder being added to the Deferred TRA Amount. 

(b) Subject to Section 3.5(c), the Corporate Taxpayer shall pay the Deferred TRA Amount as soon as practicable following the
expiration of the Five-Year Deferral Period and in no event later than October 10, 2019 (the date of such actual payment, the “Deferred TRA Payment Date”). 

(c) The Deferred TRA Amount shall not exceed the Corporate Taxpayer’s pro rata share (as of the Deferred TRA Payment Date) of the excess
of (i) Cash Available for Distribution generated during the Five-Year Deferral Period, over (ii) the actual distributions made by Spark HoldCo during the Five-Year Deferral Period.

 (d) For purposes of illustration, sample calculations of the TRA Coverage Ratio and examples of
non-deferral, full deferral, and partial deferral are set forth in Schedule B attached hereto. 
 ARTICLE IV 

TERMINATION 

Section 4.1 Early Termination, Breach of Agreement and Payment Related to Change of Control. 

(a) The Corporate Taxpayer may terminate this Agreement at any time by paying to each TRA Holder its proportionate share of the Early
Termination Payment. Upon payment of the Early Termination Payment by the Corporate Taxpayer, the Corporate Taxpayer shall not have any further payment obligations under this Agreement, other than for (i) any Tax Benefit Payment agreed to by
the Corporate Taxpayer acting in good faith and any TRA Holder as due and payable but unpaid as of the Early Termination Notice and (ii) any Tax Benefit Payment due for the Taxable Year ending with or including the date of the Early Termination
Notice (except to the extent that the amount described in clause (ii) is included in the Early Termination Payment). Upon payment of all amounts provided for in this Section 4.1(a), this Agreement shall terminate. 

(b) 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 when due, 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 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 agreed to by the Corporate Taxpayer acting in good faith and any TRA Holder as due and payable but unpaid as of the date of a breach, and
(iii) any Tax Benefit Payment due for the Taxable Year ending with or including the date of a breach. Notwithstanding the foregoing, in the event that the Corporate Taxpayer breaches this Agreement, the TRA Holders shall be entitled to elect to
receive the amounts set forth in clauses (i), (ii) and (iii) above or to seek specific performance of the terms hereof. The parties agree that the failure 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, 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


  
 13 








 
Taxpayer does not have sufficient cash to make such payment as a result of limitations imposed by existing credit agreements to which Spark HoldCo or any Subsidiary of Spark HoldCo is a party, in
which case Section 5.2 shall apply, but the Default Rate shall be replaced by the Agreed Rate); provided further that it shall be a breach of this Agreement, and the provisions in the first two sentences of this
Section 4.1(b) 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 shareholders in excess of the Target Distribution while any Tax Benefit
Payment is due and payable but unpaid. Any Tax Benefit Payment that is not paid when due pursuant to this Section 4.1(b) shall be due on the date of the next Tax Benefit Payment (the “Subsequent Due Date”). If all or a
portion of any Tax Benefit Payment is not made to any TRA Holder on the Subsequent Due Date, such payment may be further deferred pursuant to the provisions of this Section 4.1(b) and shall continue to accrue interest pursuant to
Section 5.2. 
 (c) The Corporate Taxpayer and each TRA Holder hereby acknowledges that, as of the date of this Agreement, the
aggregate value of the Tax Benefit Payments cannot reasonably be ascertained for U.S. federal income Tax or other applicable Tax purposes. 

(d) In the event of a Change of Control, all obligations hereunder shall be accelerated and such obligations shall be calculated pursuant to
this Article IV 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, (i) the Early Termination Payment calculated as if an Early Termination Notice had been
delivered on the effective date of a Change of Control, (ii) any Tax Benefit Payment in respect of a TRA Holder agreed to by the Corporation and such TRA Holder as due and payable but unpaid as of the Early Termination Notice and (iii) 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 4.2 Early Termination Notice. If the Corporate Taxpayer chooses to exercise its right of early termination under
Section 4.1(a) above, the Corporate Taxpayer shall deliver to Agent notice of such intention to exercise such right (the “Early Termination Notice”) and a schedule (the “Early Termination Schedule”)
specifying the Corporate Taxpayer’s intention to exercise such right and showing in reasonable detail the calculation of the Early Termination Payment. The Early Termination Schedule shall become final and binding on all parties thirty
(30) calendar days from the first date on which Agent has received such Schedule or amendment thereto unless Agent (i) within thirty (30) calendar days after receiving the Early Termination Schedule, provides the Corporate Taxpayer
with notice of a material objection to such Schedule made in good faith (“Material Objection Notice”) or (ii) provides a written waiver of such right of a Material Objection Notice within the period described in clause
(i) above, in which case such Schedule becomes binding on the date the waiver is received by the Corporate Taxpayer (the “Early Termination Effective Date”). If the parties, 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 Agent shall employ the Reconciliation Procedures. 

  
 14 








 Section 4.3 Payment upon Early Termination. 

(a) 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 wire transfer of immediately available funds to a bank account or accounts designated by the TRA Holder or as otherwise agreed by the Corporate Taxpayer and the TRA Holder. 

(b) “Early Termination Payment” shall equal, with respect to each TRA Holder, the present value, discounted at the Agreed
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 the TRA Holder beginning from the Early Termination Date and assuming that the Valuation Assumptions are
applied; provided that, in the event the Early Termination Effective date occurs prior to or on the same date as the Deferred TRA Payment Date, the Deferred TRA Amount shall be included in the Early Termination Payment without regard to the
limitations set forth in Section 3.5(c). 
 ARTICLE V 

SUBORDINATION AND LATE PAYMENTS 

Section 5.1 Subordination. Notwithstanding any other provision of this Agreement to the contrary, any Tax Benefit Payment,
Deferred TRA Amount or Early Termination Payment required to be made by the Corporate Taxpayer to any TRA Holder under this Agreement 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 (“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 4.1(b). 
 Section 5.2 Late Payments by the Corporate Taxpayer. The amount of all or any portion
of any Tax Benefit Payment, Deferred TRA Amount or Early Termination Payment not made to any TRA Holder when due under the terms of this Agreement shall be payable together with any interest thereon, computed at the Default Rate (or, if so provided
in Section 4.1(b), at the Agreed Rate) and commencing from the date on which such Tax Benefit Payment, Deferred TRA Amount or Early Termination Payment was due and payable. For the avoidance of doubt, no interest (other than the Accrued
Amount) shall accrue on any Deferred TRA Amount during the Five-Year Deferral Period, but interest shall accrue as provided in this Section 5.2 on the amount of all or any portion of any Deferred TRA Amount not made to any TRA Holder as
provided in Section 3.5(b). 

  
 15 








 ARTICLE VI 

NO DISPUTES; CONSISTENCY; COOPERATION 

Section 6.1 Participation in the Corporate Taxpayer’s and Spark HoldCo’s Tax Matters. Except as otherwise provided
herein, the Corporate Taxpayer shall have full responsibility for, and sole discretion over, all Tax matters concerning the Corporate Taxpayer and Spark HoldCo, including without limitation the preparation, filing or amending of any Tax Return and
defending, contesting or settling any issue pertaining to Taxes. Notwithstanding the foregoing, the Corporate Taxpayer shall notify Agent of, and keep Agent reasonably informed with respect to, the portion of any audit of the Corporate Taxpayer and
Spark HoldCo by a Taxing Authority the outcome of which is reasonably expected to affect the rights and obligations of the TRA Holders under this Agreement, and shall provide to Agent reasonable opportunity to provide information and other input to
the Corporate Taxpayer, Spark HoldCo and their respective advisors concerning the conduct of any such portion of such audit; provided, however, that the Corporate Taxpayer and Spark HoldCo shall not be required to take any action that
is inconsistent with any provision of the Spark HoldCo LLC Agreement. 
 Section 6.2 Consistency. Except upon the written advice
of a Qualified Tax Advisor, and except for items that are explicitly characterized as “deemed” or in a similar manner by the terms of this Agreement, the Corporate Taxpayer and the TRA Holders agree to report and cause to be reported for
all purposes, including U.S. federal, state, local and non-U.S. Tax purposes and financial reporting purposes, all Tax-related items (including, without limitation, the Reference Assets and each Tax Benefit Payment) in a manner consistent with that
specified by the Corporate Taxpayer in any Schedule required to be provided by or on behalf of the Corporate Taxpayer under this Agreement. Any Dispute concerning such advice shall be subject to the terms of Section 7.9. 

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 audit,
examination or controversy with any Taxing Authority, (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, and the Corporate Taxpayer shall reimburse the TRA Holder for
any reasonable third-party costs and expenses incurred pursuant to this Section 6.3. 
 ARTICLE VII

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. 

Section 7.4 Governing Law. This Agreement shall be governed by, and construed in accordance with, the law of the State of Texas,

 17 








 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; Amendments; Waivers. 

(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 Spark HoldCo Units are transferred in accordance with the terms of the Spark HoldCo LLC Agreement, the transferring TRA Holder shall have the option to assign to the transferee of such Spark HoldCo Units
the transferring TRA Holder’s rights under this Agreement with respect to such transferred Spark HoldCo 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, except as otherwise provided in such joinder, and (ii) any and all payments
payable or that may become payable to a TRA Holder pursuant to this Agreement (A) that do not arise from an Exchange and (B) that, once an Exchange has occurred, arise with respect to the Exchanged Spark HoldCo Units, 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 7.12 and acknowledging specifically the terms of Section 7.6(b). For the avoidance of doubt, if a TRA Holder transfers Spark HoldCo Units but does not assign to the transferee of such Spark
HoldCo Units the rights of such TRA Holder under this Agreement with respect to such transferred Spark HoldCo 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 Spark HoldCo Units. 
 (b) Notwithstanding the foregoing
provisions of this Section 7.6, no transferee described in clause (i) of the first sentence of Section 7.6(a) shall have the right to enforce the provisions of Section 2.3, Section 4.2, or
Section 6.2 of this Agreement, and no assignee described in clause (ii) of the first sentence of Section 7.6(a) shall have any rights under this Agreement except for the right to enforce its right to receive payments
under this Agreement. 
 (c) No provision of this Agreement may be amended unless such amendment is approved in writing by each of the
Corporate Taxpayer and Spark HoldCo and by TRA Holders who would be entitled to receive at least two-thirds of the Early Termination Payments payable to all TRA Holders hereunder if the Corporate Taxpayer had exercised its right of early termination
on the date of the most recent Exchange prior to such amendment (excluding, for purposes of this sentence, all payments made to any TRA Holder pursuant to this Agreement 

  
 18 








 
since the date of such most recent Exchange); 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. 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. 
 (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. Notwithstanding anything to the contrary herein, in the event a TRA Holder transfers his
Spark HoldCo Units to a Permitted Transferee (as defined in the Spark HoldCo LLC Agreement), such TRA Holder shall have the right, on behalf of such transferee, to enforce the provisions of Section 2.3, Section 4.2 or
Section 6.2 with respect to such transferred Spark HoldCo Units. 
 Section 7.7 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 7.8 Resolution of Disputes. 

(a) Any and all disputes which are not governed by Section 7.9, 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 7.8 and Section 7.9)
(each a “Dispute”) shall be governed by this Section 7.8. 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 [Texas] in accordance with the then-existing Rules of Arbitration of the International Chamber of Commerce. 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 International Chamber of Commerce shall make the appointment. The arbitrator shall be a lawyer admitted to the practice of
law in the State of [Texas] 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. 

  
 19 








 (b) Notwithstanding the provisions of Section 7.8(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 7.8(b), Agent and each TRA Holder (i) expressly consents to the application of Section 7.8(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) (i) EACH PARTY HEREBY IRREVOCABLY SUBMITS TO THE JURISDICTION OF COURTS LOCATED IN
HARRIS COUNTY, TEXAS, FOR THE PURPOSE OF ANY JUDICIAL PROCEEDING BROUGHT IN ACCORDANCE WITH THE PROVISIONS OF PARAGRAPH (B) OF THIS SECTION 7.8, 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 7.8(c) have a reasonable relation to this Agreement, and to the parties’ relationship with one another; and 

(ii) 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 7.8(c)(i) and such parties agree not to plead or claim the same. 

Section 7.9 Reconciliation. In the event that the Corporate Taxpayer and Agent or the relevant TRA Holder, as applicable, are
unable to resolve a disagreement with respect to the matters governed by Section 2.3, Section 4.2 and Section 6.2 within the relevant period designated in this Agreement (“Reconciliation
Dispute”), the Reconciliation Dispute shall be submitted for determination to a nationally recognized expert (the “Expert”) in the particular area of disagreement mutually acceptable to both parties. The Expert shall be a
partner or principal in a nationally recognized accounting or law firm, and unless the Corporate Taxpayer and Agent or the relevant TRA Holder agree otherwise, the Expert shall not, and the firm that employs the Expert shall not, have any material
relationship with the Corporate Taxpayer or Agent or the relevant TRA Holder, as applicable, 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 International Chamber of Commerce Centre for Expertise. The Expert shall resolve any matter relating to the


  
 20 








 
Exchange Basis Schedule or an amendment thereto or the Early Termination Schedule or an amendment thereto within thirty (30) calendar days and shall resolve any matter relating to a Tax
Benefit Schedule or an amendment thereto within fifteen (15) calendar days or as soon thereafter as is reasonably practicable, in each case after the 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, the undisputed amount 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 Agent or the relevant TRA Holder, as applicable, shall bear their own costs and expenses of such proceeding, unless
(i) the Expert adopts Agent’s or the relevant TRA Holder’s, as applicable, position, in which case the Corporate Taxpayer shall reimburse Agent or the relevant TRA Holder, as applicable, 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 Agent or the relevant TRA Holder, as applicable, 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 7.9 shall be decided by the Expert. The Expert shall finally determine any Reconciliation Dispute and the
determinations of the Expert pursuant to this Section 7.9 shall be binding on the Corporate Taxpayer and its Subsidiaries and Agent or the relevant TRA Holder, as applicable, and may be entered and enforced in any court having
jurisdiction. 
 Section 7.10 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. 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. 

Section 7.11 Admission of the Corporate Taxpayer into a Consolidated Group; Transfers of Corporate Assets. 

(a) If the Corporate Taxpayer becomes a member of an affiliated or consolidated group of corporations that files a consolidated income Tax
Return pursuant to Sections 1501 et seq. of the Code or any corresponding provisions of U.S. state or local law, then: (i) the provisions of this Agreement shall be applied with respect to the 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 taxable income of the group as a whole. 

(b) If any entity that is obligated to make a Tax Benefit Payment or Early Termination Payment hereunder transfers one or more assets to a
corporation (or a Person classified as a corporation for U.S. federal income Tax purposes) with which such entity does not file a consolidated Tax Return pursuant to Section 1501 of the Code, such entity, for purposes of


  
 21 








 
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 asset in a fully taxable transaction on the date of such contribution. The consideration deemed to be received by such entity shall be equal to the fair market value of the contributed asset,
plus (i) the amount of debt to which such asset is subject, in the case of a contribution of an encumbered asset or (ii) the amount of debt allocated to such asset, in the case of a contribution of a partnership interest. For purposes of
this Section 7.11(b), a transfer of a partnership interest shall be treated as a transfer of the transferring partner’s share of each of the assets and liabilities of that partnership. 

Section 7.12 Confidentiality. 

(a) Agent and each of its assignees and each TRA Holder and each of its 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 Spark HoldCo and its Affiliates and successors or the
TRA Holders, learned by Agent or TRA Holder heretofore or hereafter. This Section 7.12 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 Agent or a TRA Holder in violation of this Agreement) or is generally known to the business community and (ii) the disclosure of information to the extent necessary for a TRA Holder to prepare and file
its Tax Returns, to respond to any inquiries regarding the same from any Taxing Authority or to prosecute or defend any action, proceeding or audit by any Taxing Authority with respect to such returns. Notwithstanding anything to the contrary
herein, Agent and each of its assignees (and each employee, representative or other agent of 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, Spark HoldCo, Agent, 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 Agent or the TRA Holder relating to such Tax treatment and Tax structure. 

(b) If 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 7.12, the Corporate Taxpayer shall have the right and remedy to have the provisions of this Section 7.12 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 the accounts and funds managed
by the Corporate Taxpayer 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.
