Section 7. Exclusions. Notwithstanding any provision in this Agreement, the Company shall not be obligated under this
Agreement to indemnify or hold harmless Indemnitee, or, in the case of (a) and (c), to advance Expenses to Indemnitee:

payment has actually been made to or on behalf of Indemnitee under any insurance policy obtained by the Company except with respect to any excess beyond the amount paid under such insurance policy; 

(b) for an accounting of profits made from the purchase and sale (or sale and purchase) by Indemnitee of securities of the Company within the
meaning of Section 16(b) of the Exchange Act or similar provisions of state statutory law or common law; 
 (c) for any reimbursement of
the Company by Indemnitee of any bonus or other incentive-based or equity-based compensation or of any profits realized by Indemnitee from the sale of securities of the Corporation, as required in each case under the Exchange Act (including any such
reimbursements that arise from an accounting restatement of the Corporation pursuant to Section 304 of the Sarbanes-Oxley Act of 2002 (the “Sarbanes-Oxley Act”), or the payment to the Corporation of profits arising from
the purchase and sale by Indemnitee of securities in violation of Section 306 of the Sarbanes-Oxley Act), if Indemnitee is held liable therefor (including pursuant to any settlement arrangements) or in respect of claw-back provisions
promulgated under the rules and regulations of the Securities and Exchange Commission pursuant to the Dodd-Frank Wall Street Reform and Consumer Protection Act; 

(d) except as provided in Section 12(d) of this Agreement, in connection with any Proceeding (or any part of any
Proceeding) initiated by Indemnitee, including any Proceeding (or any part of any Proceeding) initiated by Indemnitee, against the Company or its directors, officers, employees or other indemnitees, unless (i) the Board authorized the
Proceeding (or any part of any Proceeding) prior to its initiation, (ii) the Company provides the indemnification, in its sole discretion, pursuant to the powers vested in the Company under applicable law or (iii) such Proceeding is being
brought by Indemnitee to assert, interpret or enforce Indemnitee’s rights under this Agreement (for the avoidance of doubt, Indemnitee shall not be deemed, for purposes of this subsection, to have initiated or brought any claim by reason of
(A) having asserted any affirmative defenses in connection with a claim not initiated by Indemnitee or (B) having made any counterclaim (whether permissive or mandatory) in connection with any claim not initiated by Indemnitee); or 

(e) if a final decision by a court having jurisdiction in the matter that is not subject to appeal shall determine that such indemnification is
not lawful. 
 Section 8. Advancement. In accordance with the pre-existing
requirements of the Bylaws, and notwithstanding any provision of this Agreement to the contrary, the Company shall advance, to the extent not prohibited by applicable law, the Expenses and Liabilities reasonably incurred by Indemnitee in connection
with any Proceeding, and such advancement shall be made 

  
 5 

 
within ten (10) days after the receipt by the Company of a statement or statements requesting such advances from time to time, whether prior to or after final disposition of any Proceeding.
Advances shall be unsecured and interest free. Advances shall be made without regard to Indemnitee’s ability to repay the Expenses and without regard to Indemnitee’s ultimate entitlement to indemnification under the other provisions of
this Agreement. Advances shall include any and all Expenses reasonably incurred pursuing an action to enforce this right of advancement, including Expenses incurred preparing and forwarding statements to the Company to support the advances claimed.
Indemnitee shall qualify for advances upon the execution and delivery to the Company of this Agreement, which shall constitute an undertaking providing that Indemnitee undertakes to repay the amounts advanced to the extent that it is ultimately
determined by final judicial decision from which there is no further right to appeal that the Indemnitee is not entitled to be indemnified by the Company. Nothing in this Section 8 shall limit Indemnitee’s right to
advancement pursuant to Section 12(d) of this Agreement. This Section 8 shall not apply to any claim made by Indemnitee for which indemnity is excluded pursuant to
Sections 7(a) or (c) hereof. 
 Section 9. Procedure for Notification and Defense of
Claim. 
 (a) Indemnitee shall promptly notify the Company in writing of any Proceeding with respect to which Indemnitee intends to
seek indemnification or advancement hereunder following the receipt by Indemnitee of written notice thereof (the date of such notification, the “Submission Date”). The written notification to the Company shall include a
description of the nature of the Proceeding and the facts underlying the Proceeding. To obtain indemnification under this Agreement, Indemnitee shall submit to the Company a written request, including therein or therewith such documentation and
information as is reasonably available to Indemnitee and is reasonably necessary to determine whether and to what extent Indemnitee is entitled to indemnification following the final disposition of such Proceeding, including any appeal therein. Any
delay or failure by Indemnitee to notify the Company hereunder will not relieve the Company from any liability which it may have to Indemnitee hereunder or otherwise than under this Agreement, and any delay or failure in so notifying the Company
shall not constitute a waiver by Indemnitee of any rights under this Agreement. The Secretary of the Company shall, promptly upon receipt of such a request for indemnification, advise the Board in writing that Indemnitee has requested
indemnification. 
 (b) In the event Indemnitee is entitled to indemnification and/or advancement with respect to any Proceeding, Indemnitee
may, at Indemnitee’s option, (i) retain counsel (including local counsel) selected by Indemnitee and approved by the Company to defend Indemnitee in such Proceeding, at the sole expense of the Company (which approval shall not be
unreasonably withheld, conditioned or delayed), or (ii) have the Company assume the defense of Indemnitee in such Proceeding, in which case the Company shall assume the defense of such Proceeding with counsel selected by the Company and
approved by Indemnitee (which approval shall not be unreasonably withheld, conditioned or delayed) within ten (10) days of the Company’s receipt of written notice of Indemnitee’s election to cause the Company to do so. If the Company
is required to assume the defense of any such Proceeding, it shall engage legal counsel for such defense, and the Company shall be solely responsible for all fees and expenses of such legal counsel and otherwise of such defense. Such legal counsel
may represent both Indemnitee and the Company (and any other party or parties entitled to be indemnified by the 

  
 6 

 
Company with respect to such matter) unless, in the reasonable opinion of legal counsel to Indemnitee, there is a conflict of interest between Indemnitee and the Company (or any other such party
or parties) or there are legal defenses available to Indemnitee that are not available to the Company (or any such other party or parties). Notwithstanding either party’s assumption of responsibility for defense of a Proceeding, each party
shall have the right to engage separate counsel at its own expense. If the Company has responsibility for defense of a Proceeding, the Company shall provide the Indemnitee and its counsel with all copies of pleadings and material correspondence
relating to the Proceeding. Indemnitee and the Company shall reasonably cooperate in the defense of any Proceeding with respect to which indemnification is sought hereunder, regardless of whether the Company or Indemnitee assumes the defense
thereof. Indemnitee may not settle or compromise any Proceeding without the prior written consent of the Company, which consent shall not be unreasonably withheld, conditioned or delayed. The Company may not settle or compromise any Proceeding
without the prior written consent of Indemnitee. 
 Section 10. Procedure Upon Application for Indemnification. 

(a) Upon written request by Indemnitee for indemnification pursuant to Section 9(a) hereof, if any determination by
the Company is required by applicable law with respect to Indemnitee’s entitlement thereto, such determination shall be made (i) if Indemnitee shall request such determination be made by Independent Counsel, by Independent Counsel, and
(ii) in all other circumstances, (A) by a majority vote of the Disinterested Directors, even though less than a quorum of the Board, (B) by a committee of Disinterested Directors designated by a majority vote of the Disinterested
Directors, even though less than a quorum of the Board, (C) if there are no such Disinterested Directors or, if such Disinterested Directors so direct, by Independent Counsel in a written opinion to the Board, a copy of which shall be delivered
to Indemnitee, or (D) if so directed by the Board, by the stockholders of the Company holding a majority of the securities of the Company entitled to vote; and, if it is so determined that Indemnitee is entitled to indemnification, payment to
Indemnitee shall be made within ten (10) days after such determination. Indemnitee shall cooperate with the person, persons or entity making such determination with respect to Indemnitee’s entitlement to indemnification, including
providing to such person, persons or entity upon reasonable advance request any documentation or information which is not privileged or otherwise protected from disclosure and which is reasonably available to Indemnitee and reasonably necessary to
such determination. Any Expenses incurred by Indemnitee in so cooperating with the person, persons or entity making such determination shall, to the fullest extent permitted by law, be borne by the Company (irrespective of the determination as to
Indemnitee’s entitlement to indemnification) and the Company hereby indemnifies and agrees to hold Indemnitee harmless therefrom. The Company will not deny any written request for indemnification hereunder made in good faith by Indemnitee
unless a determination as to Indemnitee’s entitlement to such indemnification described in this Section 10(a) has been made. The Company agrees to pay the reasonable fees and expenses of the Independent Counsel
referred to above and to fully indemnify such counsel against any and all Liabilities and Expenses arising out of or relating to this Agreement or its engagement pursuant hereto. 

  
 7 

 (b) In the event the determination of entitlement to indemnification is to be made by Independent
Counsel pursuant to Section 10(a) hereof, (i) the Independent Counsel shall be selected by the Company within ten (10) days of the Submission Date (the cost of such Independent Counsel to be paid by the Company),
(ii) the Company shall give written notice to Indemnitee advising it of the identity of the Independent Counsel so selected and (iii) Indemnitee may, within ten (10) days after such written notice of selection shall have been given,
deliver to the Company Indemnitee’s written objection to such selection. Such objection by Indemnitee may be asserted only on the ground that the Independent Counsel selected does not meet the requirements of “Independent Counsel” as
defined in this Agreement. If such written objection is made and substantiated, the Independent Counsel selected shall not serve as Independent Counsel unless and until Indemnitee withdraws the objection or a court has determined that such objection
is without merit. Absent a timely objection, the person so selected shall act as Independent Counsel. If no Independent Counsel shall have been selected and not objected to before the later of (A) thirty (30) days after the Submission Date
and (B) ten (10) days after the final disposition of the Proceeding, including any appeal therein, each of the Company and Indemnitee shall select a law firm or member of a law firm meeting the qualifications to serve as Independent
Counsel, and such law firms or members of law firms shall select the Independent Counsel. 
 Upon the due commencement of any judicial proceeding or
arbitration pursuant to Section 12(a) of this Agreement, Independent Counsel shall be discharged and relieved of any further responsibility in such capacity (subject to the applicable standards of professional conduct then
prevailing). 
 Section 11. Presumptions and Effect of Certain Proceedings. 

(a) In making a determination with respect to entitlement to indemnification hereunder, the person, persons or entity making such determination
shall, to the fullest extent not prohibited by applicable law, presume that Indemnitee is entitled to indemnification under this Agreement if Indemnitee has submitted a request for indemnification in accordance with
Section 9(a) of this Agreement, and the Company shall, to the fullest extent not prohibited by applicable law, have the burden of proof to overcome that presumption in connection with the making by any person, persons or
entity of any determination contrary to that presumption. Neither the failure of the Company (including by its directors or Independent Counsel) to have made a determination prior to the commencement of any action pursuant to this Agreement that
indemnification is proper in the circumstances because Indemnitee has met the applicable standard of conduct, nor an actual determination by the Company (including by its directors or Independent Counsel) that Indemnitee has not met such applicable
standard of conduct, shall be a defense to the action or create a presumption that Indemnitee has not met the applicable standard of conduct. 

(b) Subject to Section 12(e) hereof, if the person, persons or entity empowered or selected under
Section 10 of this Agreement to determine whether Indemnitee is entitled to indemnification shall not have made a determination within sixty (60) days after receipt by the Company of the request therefore, the
requisite determination of entitlement to indemnification shall, to the fullest extent not prohibited by applicable law, be deemed to have been made and Indemnitee shall be entitled to such indemnification, absent a prohibition of such
indemnification under applicable law; provided, however, that such 60-day period may be extended for a reasonable time, not to exceed an additional thirty (30) days, if (i) the 

  
 8 

 
determination is to be made by Independent Counsel and Indemnitee objects to the Company’s selection of Independent Counsel and (ii) the Independent Counsel ultimately selected requires
such additional time for the obtaining or evaluating of documentation or information relating thereto; provided further, however, that such 60-day period may also be extended for a reasonable time, not to exceed an additional sixty (60) days,
if the determination of entitlement to indemnification is to be made by the stockholders of the Company. 
 (c) The termination of any
Proceeding or of any claim, issue or matter therein, by judgment, order, settlement or conviction, or upon a plea of nolo contendere or its equivalent, shall not (except as otherwise expressly provided in this Agreement) adversely affect the right
of Indemnitee to indemnification or create a presumption that Indemnitee did not act in good faith and in a manner which Indemnitee reasonably believed to be in or not opposed to the best interests of the Company or, with respect to any criminal
Proceeding, that Indemnitee had reasonable cause to believe that Indemnitee’s conduct was unlawful. 
 (d) Reliance as Safe
Harbor. For purposes of any determination of good faith, Indemnitee shall be deemed to have acted in good faith if Indemnitee’s action is based on the records or books of account of the Enterprise, including financial statements, or on
information supplied to Indemnitee by the officers of the Enterprise in the course of their duties, or on the advice of legal counsel for the Enterprise or on information or records given or reports made to the Enterprise by an independent certified
public accountant or by an appraiser or other expert selected with the reasonable care by the Enterprise. The provisions of this Section 11(d) shall not be deemed to be exclusive or to limit in any way the other
circumstances in which Indemnitee may be deemed to have met the applicable standard of conduct set forth in this Agreement. 
 (e)
Actions of Others. The knowledge or actions, or failure to act, of any director, officer, agent or employee of the Enterprise shall not be imputed to Indemnitee for purposes of determining the right to indemnification under this
Agreement. 
 Section 12. Remedies of Indemnitee. 

(a) Subject to Section 12(e) hereof, in the event that (i) a determination is made pursuant to
Section 10 of this Agreement that Indemnitee is not entitled to indemnification under this Agreement, (ii) advancement is not timely made pursuant to Section 8 of this Agreement, (iii) no
determination of entitlement to indemnification shall have been timely made pursuant to Section 10(a) of this Agreement within sixty (60) days after receipt by the Company of the request for indemnification,
(iv) payment of indemnification is not made pursuant to Sections 4 or 5 or the third to the last sentence of Section 10(a) of this Agreement within ten (10) days after receipt by the Company of a written request
therefor, (v) payment of indemnification pursuant to Sections 2, 3 or 6 of this Agreement is not made within ten (10) days after a determination has been made that Indemnitee is entitled to
indemnification, or (vi) in the event that the Company or any other Person takes or threatens to take any action to declare this Agreement void or unenforceable, or institutes any litigation or other action or proceeding designed to deny, or to
recover from, Indemnitee the benefits provided or intended to be provided to Indemnitee hereunder, Indemnitee shall be entitled to an adjudication by a court of Indemnitee’s entitlement to such indemnification or advancement. Alternatively,
Indemnitee, at Indemnitee’s option, may seek an award in arbitration to be conducted by a single arbitrator pursuant to the Commercial Arbitration Rules of the American Arbitration Association. The Company shall not oppose Indemnitee’s
right to seek any such adjudication or award in arbitration. 

  
 9 

 (b) In the event that a determination shall have been made pursuant to
Section 10(a) of this Agreement that Indemnitee is not entitled to indemnification, any judicial proceeding or arbitration commenced pursuant to this Section 12 shall be conducted in all respects
as a de novo trial, or arbitration, on the merits and Indemnitee shall not be prejudiced by reason of that adverse determination. In any judicial proceeding or arbitration commenced pursuant to this Section 12 the Company
shall have the burden of proving Indemnitee is not entitled to indemnification or advancement, as the case may be. 
 (c) If a determination
shall have been made pursuant to Section 10(a) of this Agreement that Indemnitee is entitled to indemnification, the Company shall be bound by such determination in any judicial proceeding or arbitration commenced pursuant
to this Section 12, absent a prohibition of such indemnification under applicable law. 
 (d) The Company shall, to
the fullest extent not prohibited by applicable law, be precluded from asserting in any judicial proceeding or arbitration commenced pursuant to this Section 12 that the procedures and presumptions of this Agreement are not
valid, binding and enforceable and shall stipulate in any such court or before any such arbitrator that the Company is bound by all the provisions of this Agreement. It is the intent of the Company that Indemnitee not be required to incur Expenses
associated with the interpretation, enforcement or defense of Indemnitee’s rights under this Agreement by litigation or otherwise because the cost and expense thereof would substantially detract from the benefits intended to be extended to
Indemnitee hereunder. The Company shall indemnify Indemnitee against any and all Expenses and, if requested by Indemnitee, shall (within ten (10) days after receipt by the Company of a written request therefore) advance, to the extent not
prohibited by applicable law, such Expenses to Indemnitee, which are incurred by Indemnitee in connection with any action brought by Indemnitee for indemnification or advancement from the Company under this Agreement or the Bylaws, or under any
directors’ and officers’ liability insurance policies maintained by the Company, regardless of whether Indemnitee ultimately is determined to be entitled to such indemnification, advancement or insurance recovery, as the case may be. 

(e) Notwithstanding anything in this Agreement to the contrary, no determination as to entitlement to indemnification under this Agreement
shall be required to be made prior to the final disposition of the Proceeding, including any appeal therein; provided that, in absence of any such determination with respect to such Proceeding, the Company shall advance Expenses with respect to such
Proceeding. 
 Section 13. Non-Exclusivity; Survival of Rights; Insurance;
Subrogation. 
 (a) The rights of indemnification and to receive advancement as provided by this Agreement shall not be deemed
exclusive of any other rights to which Indemnitee may at any time be entitled under applicable law, the Certificate of Incorporation, the Bylaws, any agreement, a vote of stockholders or a resolution of directors, or otherwise. No amendment,

  
 10 

 
alteration or repeal of this Agreement or of any provision hereof shall limit or restrict any right of Indemnitee under this Agreement in respect of any action taken or omitted by such Indemnitee
in Indemnitee’s Corporate Status prior to such amendment, alteration or repeal. The Company shall not adopt any amendment or alteration to, or repeal of, the Certificate of Incorporation or the Bylaws, the effect of which would be to deny,
diminish or encumber the Indemnitee’s rights to indemnification pursuant to this Agreement, the Certificate of Incorporation, the Bylaws or applicable law relative to such rights prior to such amendment, alteration or repeal. To the extent that
a change in Delaware law, whether by statute or judicial decision, permits greater indemnification or advancement than would be afforded currently under the Bylaws or this Agreement, it is the intent of the parties hereto that Indemnitee shall enjoy
by this Agreement the greater benefits so afforded by such change. No right or remedy herein conferred is intended to be exclusive of any other right or remedy, and every other right and remedy shall be cumulative and in addition to every other
right and remedy given hereunder or now or hereafter existing at law or in equity or otherwise. The assertion or employment of any right or remedy hereunder, or otherwise, shall not prevent the concurrent assertion or employment of any other right
or remedy. 
 (b) The Company hereby acknowledges that Indemnitee may have certain rights to indemnification, advancement and insurance
provided by one or more Persons with whom or which Indemnitee may be associated. The Company hereby acknowledges and agrees that (i) the Company shall be the indemnitor of first resort with respect to any Proceeding, Expense,
Liability or matter that is the subject of the Indemnity Obligations, (ii) the Company shall be primarily liable for all Indemnity Obligations and any indemnification afforded to Indemnitee in respect of any Proceeding, Expense,
Liability or matter that is the subject of Indemnity Obligations, whether created by applicable law, organizational or constituent documents, contract (including this Agreement) or otherwise, (iii) any obligation of any other
Persons with whom or which Indemnitee may be associated to indemnify Indemnitee or advance Expenses or Liabilities to Indemnitee in respect of any Proceeding shall be secondary to the obligations of the Company hereunder, (iv) the
Company shall be required to indemnify Indemnitee and advance Expenses or Liabilities to Indemnitee hereunder to the fullest extent provided herein without regard to any rights Indemnitee may have against any other Person with whom or which
Indemnitee may be associated or insurer of any such Person and (v) the Company irrevocably waives, relinquishes and releases any other Person with whom or which Indemnitee may be associated from any claim of contribution,
subrogation or any other recovery of any kind in respect of amounts paid by the Company hereunder. In the event any other Person with whom or which Indemnitee may be associated or their insurers advances or extinguishes any liability or loss
which is the subject of any Indemnity Obligation owed by the Company or payable under any Company insurance policy, the payor shall have a right of subrogation against the Company or its insurer or insurers for all amounts so paid which would
otherwise be payable by the Company or its insurer or insurers under this Agreement. In no event will payment of an Indemnity Obligation by any other Person with whom or which Indemnitee may be associated or their insurers affect the obligations of
the Company hereunder or shift primary liability for any Indemnity Obligation to any other Person with whom or which Indemnitee may be associated. Any indemnification, insurance or advancement provided by any other Person with whom or which
Indemnitee may be associated with respect to any liability arising as a result of Indemnitee’s Corporate Status or capacity as an officer or director of any Person is specifically in excess over any Indemnity Obligation of the Company or valid
and any collectible insurance (including but not limited to any malpractice insurance or professional errors and omissions insurance) provided by the Company under this Agreement. 

  
 11 

 (c) The Company shall maintain an insurance policy or policies providing liability insurance
providing reasonable and customary coverage as compared with similarly situated companies (as determined by the Board in its reasonable discretion) for directors, officers, employees, trustees, or agents of any Enterprise, and Indemnitee shall be
covered by such policy or policies in accordance with its or their terms to the maximum extent of the coverage available for any such director, officer, employee, trustee or agent under such policy or policies and such policies shall provide for and
recognize that the insurance policies are primary to any rights to indemnification, advancement or insurance proceeds to which Indemnitee may be entitled from one or more Persons with whom or which Indemnitee may be associated to the same extent as
the Company’s indemnification and advancement obligations set forth in this Agreement. If, at the time of the receipt of a notice of a claim pursuant to the terms hereof, the Company has director and officer liability insurance in effect, the
Company shall give prompt notice of the commencement of such Proceeding to the insurers in accordance with the procedures set forth in the respective policies. The Company shall thereafter take all necessary or desirable action to cause such
insurers to pay, on behalf of Indemnitee, all amounts payable as a result of such Proceeding in accordance with the terms of such policies. 

(d) In the event of any payment under this Agreement, the Company shall be subrogated to the rights of recovery of Indemnitee, including rights
of indemnification provided to Indemnitee from any other person or entity with whom Indemnitee may be associated; provided, however, that the Company shall not be subrogated to the extent of any such payment of all rights of recovery of Indemnitee
with respect to any Person with whom or which Indemnitee may be associated. 
 (e) The indemnification and contribution provided for in this
Agreement will remain in full force and effect regardless of any investigation made by or on behalf of Indemnitee.

or agent of the Company or any other Enterprise, (ii) one (1) year after the date of final termination of any Proceeding, including any appeal, then pending in respect of which Indemnitee is granted rights of indemnification or advancement
hereunder and of any proceeding, including any appeal, commenced by Indemnitee pursuant to Section 12 of this Agreement relating thereto or (iii) the expiration of all statutes of limitation applicable to possible
Proceedings to which Indemnitee may be subject arising out of Indemnitee’s Corporate Status. The indemnification provided under this Agreement shall continue as to the Indemnitee even though he or she may have ceased to be a director or officer
of the Company or of any of the Company’s direct or indirect subsidiaries or to have Corporate Status. This Agreement shall be binding upon the Company and its successors and assigns and shall inure to the benefit of Indemnitee and
Indemnitee’s heirs, executors and administrators. The Company shall require and cause any successor, and any direct or indirect parent of any successor, whether direct or indirect by purchase, merger, consolidation or otherwise, to all,
substantially all or a substantial part, of the business and/or assets of the 

  
 12 

 
Company, by written agreement in form and substance satisfactory to Indemnitee, expressly to assume and agree to perform this Agreement in the same manner and to the same extent that the Company
would be required to perform if no such succession had taken place. This Agreement shall not be deemed an employment contract between the Company (or any of its subsidiaries or any other Enterprise) and Indemnitee. Indemnitee specifically
acknowledges that Indemnitee’s employment with the Company (or any of its subsidiaries or any other Enterprise), if any, is at will, and Indemnitee may be discharged at any time for any reason, with or without cause, except as may be otherwise
provided in any written employment contract between Indemnitee and the Company (or any of its subsidiaries or any other Enterprise), other applicable formal severance policies duly adopted by the Board, or, with respect to service as a director of
the Company, by the Certificate of Incorporation, the Bylaws or the DGCL. 
 Section 15. Severability. If any provision
or provisions of this Agreement shall be held to be invalid, illegal or unenforceable for any reason whatsoever: (a) the validity, legality and enforceability of the remaining provisions of this Agreement (including, without limitation, each
portion of any Section of this Agreement containing any such provision held to be invalid, illegal or unenforceable that is not itself invalid, illegal or unenforceable) shall not in any way be affected or impaired thereby and shall remain
enforceable to the fullest extent permitted by applicable law; (b) such provision or provisions shall be deemed reformed to the extent necessary to conform to applicable law and to give the maximum effect to the intent of the parties hereto;
and (c) to the fullest extent possible, the provisions of this Agreement (including, without limitation, each portion of any Section of this Agreement containing any such provision held to be invalid, illegal or unenforceable that is not itself
invalid, illegal or unenforceable) shall be construed so as to give effect to the intent manifested thereby. 
 Section 16.
Enforcement. 
 (a) The Company expressly confirms and agrees that it has entered into this Agreement and assumed the
obligations imposed on it hereby in order to induce Indemnitee to serve as a director, officer, employee or agent of the Company, and the Company acknowledges that Indemnitee is relying upon this Agreement in serving as a director, officer, employee
or agent of the Company. 
 (b) This Agreement constitutes the entire agreement between the parties hereto with respect to the subject matter
hereof and supersedes all prior agreements and understandings, oral, written and implied, between the parties hereto with respect to the subject matter hereof; provided, however, that this Agreement is a supplement to and in furtherance of the
Certificate of Incorporation, the Bylaws and applicable law, and shall not be deemed a substitute therefore, nor diminish or abrogate any rights of Indemnitee thereunder. 

Section 17. Modification and Waiver. No supplement, modification or amendment of this Agreement shall be binding unless
executed in writing by the parties thereto. No waiver of any of the provisions of this Agreement shall be deemed to be or shall constitute a waiver of any other provision of this Agreement nor shall any waiver constitute a continuing waiver.

 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

  
 11 

 
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. 

  
 13 

 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 

  
 14 

 
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) 

  
 15 

 
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 

  
 16 

 
(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 

  
 17 

 
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 

  
 18 

 
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.

If to a TRA Holder, other than an Agent, that is or was a partner in Solaris LLC, to: 

The address set forth in the records of Solaris LLC. 

Any party may change its address or fax number by giving the other party written notice of its new address or fax number in the manner set forth above. 

Section 7.2 Counterparts. This Agreement may be executed in one or more counterparts, all of which shall be considered one and the
same agreement and shall become effective when one or more counterparts have been signed by each of the parties and delivered to the other parties, it being understood that all parties need not sign the same counterpart. Delivery of an executed
signature page to this Agreement by facsimile transmission shall be as effective as delivery of a manually signed counterpart of this Agreement. 

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 

  
 20 

 
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. 

  
 21 

 (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. 

  
 22 

 (b) Notwithstanding the provisions of Section 7.9(a), the Corporate Taxpayer may bring an
action or special proceeding in any court of competent jurisdiction for the purpose of compelling a party to arbitrate, seeking temporary or preliminary relief in aid of an arbitration hereunder, and/or enforcing an arbitration award and, for the
purposes of this Section 7.9(b), 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 

  
 23 

 
Early Termination Schedule or an amendment thereto within thirty (30) calendar days, (b) any matter relating to a Tax Benefit Payment Schedule or an amendment thereto within fifteen
(15) calendar days , and (c) any matter related to treatment of any tax-related item as contemplated in Section 6.2 within fifteen (15) calendar days, or, in each case,
as soon thereafter as is reasonably practicable after such matter has been submitted to the Expert for resolution. Notwithstanding the preceding sentence, if the matter is not resolved before any payment that is the subject of a disagreement would
be due (in the absence of such disagreement) or any Tax Return reflecting the subject of a disagreement is due, any portion of such payment that is not under dispute shall be paid on the date prescribed by this Agreement and such Tax Return may be
filed as prepared by the Corporate Taxpayer, subject to adjustment or amendment upon resolution. The costs and expenses relating to the engagement of such Expert or amending any Tax Return shall be borne by the Corporate Taxpayer except as provided
in the next sentence. The Corporate Taxpayer and the Disputing Party shall each bear its own costs and expenses of such proceeding, unless (i) the Expert adopts such Disputing Party’s position, in which case the Corporate Taxpayer shall
reimburse such Disputing Party for any reasonable out-of-pocket costs and expenses in such proceeding, or (ii) the Expert adopts the Corporate Taxpayer’s
position, in which case such Disputing Party shall reimburse the Corporate Taxpayer for any reasonable out-of-pocket costs and expenses in such proceeding. Any dispute
as to whether a dispute is a Reconciliation Dispute within the meaning of this Section 7.10 shall be decided by the Expert. The Expert shall finally determine any Reconciliation Dispute and the determinations of the Expert
pursuant to this Section 7.10 shall be binding on the Corporate Taxpayer and its Subsidiaries and the Disputing Party and may be entered and enforced in any court having jurisdiction. 

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

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

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

  
 24 

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

Section 7.13 Confidentiality. 

(a) Each 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

  
 25 

 
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. 

  
 26 

 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.
