inventory and other current assets) owned by the Company Group on the IPO Date or (ii) any increase of the tax basis of the Company Group’s assets arising from the Pre-IPO Reorganization Transactions. 

“Valuation Assumptions” means, as of an Early Termination Date, the assumptions that (a) in each Taxable Year ending on or
after such Early Termination Date, the Company Group will generate taxable income sufficient to fully utilize all Covered Tax Assets (in accordance with all applicable limitations) during such Taxable Year or future Taxable Years, as
applicable; (b) the U.S. federal and Canadian federal and provincial income Tax rates that will be in effect for each such Taxable Year will be those specified for each such Taxable Year by the Code, the Canadian Tax Act, applicable provincial
law and other law as in effect on the Early Termination Date; (c) the effective state and local income tax rates that will be in effect for each such Taxable Year shall be 5%; (d) any non-amortizable assets will be disposed of on the fifteenth
anniversary of the IPO in a fully taxable transaction for U.S. federal, Canadian federal and provincial and non-U.S. and non-Canadian income tax purposes; provided that in the event of a Change of Control, such non-amortizable assets shall be
deemed disposed of at the time of sale of the relevant asset if earlier than such fifteenth anniversary; (e) any payment obligations pursuant to this Agreement will be satisfied on the date that any Tax Return to which such payment 

  
 10 

 
obligation relates is required to be filed excluding any extensions; and (f) to the extent relevant for purposes of determining any amount deemed paid under the Long-Term Incentive Plan, if such
Early Termination Date arises by reason of a transaction in which there is a sale of Common Stock to a Person that is not an Affiliate of the Company (an “LTIP Trigger Transaction”), all of the stock then owned by the LTIP Party was
sold at the price at which such stock was sold in the LTIP Trigger Transaction on such Early Termination Date (it being understood that if all of the stock held by the LTIP Party prior to such LTIP Trigger Transaction is in fact sold in such LTIP
Trigger Transaction, then the amount and price of such stock sold shall be determined entirely by reference to the LTIP Trigger Transaction) and, otherwise, that all stock then owned by the LTIP Party was sold on such Early Termination Date at its
fair market value as of such date. 
 ARTICLE 2 

DETERMINATION OF REALIZED TAX BENEFIT 

Section 2.01. Covered Tax Assets. The Company, on the one hand, and the TRA Parties, on the other hand, acknowledge that
the Company Group may, and to the extent permitted by applicable law and consistent with the principles set forth under Section 2.02(b) shall, reduce the amount of Taxes that the Company Group would otherwise be required to pay in the future as a
result of the Covered Tax Assets. 
 Section 2.02. Tax Benefit Schedule. 

(a) Tax Benefit Schedule. Within 45 calendar days after the filing of the Company’s U.S. federal income Tax Return for a
Taxable Year, the Company shall provide to the TRA Party Representative a schedule showing, in reasonable detail, (i) the calculation of the Covered Tax Benefit (if any) and the Tax Benefit Payment (if any) for such Taxable Year (together, a
“Tax Benefit Schedule”) and (ii) supporting information (including work papers and valuation reports) reasonably necessary to support the calculation of such payment. The Schedule will become final as provided in Section 2.03(a) and
may be amended as provided in Section 2.03(b) (subject to the procedures set forth in Section 2.03(a)). 
 (b) Applicable
Principles. For purposes of calculating the Covered Tax Benefit, carryovers or carrybacks of any Tax item attributable to the Covered Tax Assets shall be considered to be subject to the rules of the Code (or any successor statute) and the
Treasury Regulations (and any relevant provisions of the Canadian Tax Act, state, provincial or local tax law) governing the use, limitation and expiration of carryovers or carrybacks of the relevant type; provided, however, that the
Covered Tax Assets treated as resulting in a Realized Tax Benefit for one Taxable Year shall not be treated as resulting in a Realized Tax Benefit for any other Taxable Year. In addition, for purposes of determining the Realized Tax Benefit for
any Taxable Year, the Company Group shall be assumed (i) to utilize any item of loss, deduction or credit arising in such Taxable Year (and permitted to be utilized in such Taxable Year) before carrying back or carrying forward to such Taxable Year,
or otherwise utilizing in such Taxable Year, any Covered Tax Asset that is permitted to be so carried back, carried forward or utilized; (ii) to utilize any available Covered Tax Asset that is permitted (or, for the avoidance of doubt, that would be
so permitted but for a Post-IPO Tax Asset) to be carried back, carried forward or utilized in such Taxable Year before utilizing any Post-IPO Tax Asset, and (iii) to utilize any 

  
 11 

 
Covered Tax Asset in the earliest Taxable Year in which such Covered Tax Asset is permitted to be utilized. If a carryover or carryback of any Tax attribute includes a portion that is
attributable to the Covered Tax Assets (a “TRA Portion”) and another portion that is not (a “Non-TRA Portion”), the Company shall be assumed to utilize the TRA Portion before utilizing the Non-TRA Portion. 

Section 2.03. Procedures, Amendments.

(a) Procedure. Each time the Company delivers an applicable Schedule to the TRA Party Representative under this Agreement,
including any Amended Schedule delivered pursuant to Section 2.03(b) and any Early Termination Schedule or amended Early Termination Schedule delivered pursuant to the procedures set forth in Section 4.02, the Company shall also: (i) deliver
supporting schedules and work papers, as determined by the Company or as reasonably requested by the TRA Party Representative that provide a reasonable level of detail regarding the data and calculations that were relevant for purposes of preparing
the Schedule; (ii) deliver an Advisory Firm Letter supporting such Schedule; (iii) deliver a declaration signed by the chief financial officer of the Company to the effect that the activities underlying the computations reflected in the Schedule
have been made without regard to any transaction which was substantially motivated by the intent to reduce or defer any Tax Benefit Payment or Early Termination Payment; and (iv) allow the TRA Party Representative and its advisors to have reasonable
access to the appropriate representatives, as determined by the Company or as reasonably requested by the TRA Party Representative at the Company and the Advisory Firm in connection with a review of such Schedule. Without limiting the
generality of the preceding sentence, the Company shall ensure that any Tax Benefit Schedule that is delivered to the TRA Party Representative along with any supporting schedules and work papers, provides a reasonably detailed presentation of the
calculation of the Actual Tax Liability (the “with” calculation) and the Non-Tax Benefit Tax Liability (the “without” calculation), and identifies any material assumptions or operating procedures or principles that were used for
purposes of such calculations. An applicable Schedule or amendment thereto shall become final and binding on the Parties thirty calendar days from the date on which the TRA Party Representative first received the applicable Schedule or
amendment thereto unless: 
 (i) the TRA Party Representative, within thirty calendar days after receiving the applicable
Schedule or amendment thereto, provides the Company with written notice of a material objection to such Schedule that is made in good faith and that sets forth in reasonable detail the TRA Parties’ material objection (an “Objection
Notice”); or 
 (ii) the TRA Party Representative provides a written waiver of its right to deliver an Objection
Notice within the time period described in clause (i) above, in which case such Schedule or amendment thereto becomes binding on the date the waiver from the TRA Party Representative is received by the Company. 

In the event that the TRA Party Representative timely delivers an Objection Notice pursuant to clause (i) above, and if the Parties, for any reason, are
unable to successfully resolve the issues raised in the Objection Notice within thirty calendar days after receipt by the Company of the Objection Notice, the Company and the TRA Party Representative shall employ the reconciliation procedures as
described in Section 7.11 of this Agreement (the “Reconciliation Procedures”).

  
 12 

 (b) Amended Schedule. The applicable Schedule for any Taxable Year may be amended
from time to time by the Company (i) in connection with a Determination affecting the 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 the TRA Party Representative; (iii) to reflect a material change (relative to the amounts in the original Schedule) in the Realized Tax Benefit for such Taxable Year attributable to an amended Tax Return
filed for such Taxable Year, in each case with respect to any member of the Company Group; or (iv) to comply with the Expert’s determination under the Reconciliation Procedures (such amended Schedule, an “Amended Schedule”);
provided, however, that such a change under clause (i) shall not be taken into account on an Amended Schedule unless and until there has been a Determination with respect to such change. The Company shall deliver any Amended
Schedule to the TRA Party Representative within 30 calendar days of any of the foregoing events described in clauses (i) through (iv) occurring, and any such Amended Schedule shall be subject to the procedures set forth in Section 2.03(a). 

ARTICLE 3 
 TAX
BENEFIT PAYMENTS 
 Section 3.01. Payments.

(a) Payments. Within five Business Days of a Tax Benefit Schedule with respect to a Taxable Year becoming final in accordance with
Section 2.03(a) or Section 7.11, the Company shall pay to each of the TRA Parties an amount equal to the TRA Party’s Applicable Percentage multiplied by the Tax Benefit Payment for such Taxable Year determined pursuant to Section
3.01(b). Each such Tax Benefit Payment shall be made by wire transfer of immediately available funds to a bank account designated to the Company by the applicable TRA Party or as otherwise agreed by the Company and the applicable TRA Party.

 (b) Amount of Payments. A “Tax Benefit Payment” shall equal, with respect to any Taxable Year, the amount of
Covered Tax Benefits, if any, for the Taxable Year, increased by: 
 (i) interest calculated at the Agreed Rate from the due
date (without extensions) for filing the U.S. federal income Tax Return with respect to Taxes for such Taxable Year until the Payment Date; and 

(ii) any increase in a Covered Tax Benefit that has become final under Section 2.03(b), together with interest calculated at
the Agreed Rate from the original Payment Date with respect to the Schedule that was amended; 

provided, however, that the amounts described in Section 3.01(b)(ii) above shall not be taken into account in determining a Tax Benefit Payment
attributable to any Taxable Year to the extent such amounts were taken into account in determining any Tax Benefit Payment for a preceding Taxable Year. Notwithstanding the foregoing, for each Taxable Year ending on or after a Change of
Control, all Tax Benefit Payments shall be calculated by using Valuation Assumptions (a), (d), (e) and (f), substituting in each case the terms “the closing date of a Change of Control” for an “Early Termination Date.” 

  
 13 

 Section 3.02. Offsets. In the event that a Tax Benefit Schedule is
amended pursuant to Section 2.03(b) for any Taxable Year reflecting a decrease in the Tax Benefit Payment for such year and payments have previously been made based on the greater Tax Benefit Payment (such excess, an “Excess
Payment”), any amounts that would otherwise be due to the TRA Parties at any subsequent time under Section 3.01(b) shall be reduced (but not below zero) until the aggregate amount of such reduction equals the amount of such Excess Payment.
For the avoidance of doubt, if all future payments are insufficient to repay any Excess Payment, the TRA Parties shall have no obligation to return such Excess Payment to the Company. 

Section 3.03. 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. 
 Section 3.04. Change Notices. If the Company or any of its
Subsidiaries receives a 30-day letter, a final audit report, a statutory notice of deficiency or similar written notice from the IRS, CRA or any Taxing Authority with respect to the Tax treatment of any Covered Tax Asset (a “Change
Notice”), which, if sustained, would result in (a) a reduction in the amount of Realized Tax Benefit with respect to a Taxable Year preceding the taxable year in which the Change Notice is received or (b) a reduction in the amount of Tax
Benefit Payments, the Company will be required to pay to the TRA Parties with respect to Taxable Years after and including the year in which the Change Notice is received, prompt written notice shall be given to the TRA Party Representative. 

ARTICLE 4 

TERMINATION 

Section 4.01. Early Termination; Breach of Agreement; Credit Events.

(a) Company’s Early Termination Right. With the written approval of (x) a majority of the Independent Directors
of the Board and (y) the TRA Party Representative, the Company may terminate this Agreement by paying to the TRA Parties the Early Termination Payment. Upon the Company’s payment of the Early Termination Payment, the Company shall not have
any further payment obligations under this Agreement, other than with respect to any: (A) prior Tax Benefit Payment agreed to by the Company and the TRA Party Representative as due and payable but unpaid as of the date the Early Termination Notice
is delivered and (B) current Tax Benefit Payment due for the Taxable Year ending prior to, with or including the date of the Early Termination Notice (except to the extent that such amount is included in the Early Termination Payment). 

(b) Acceleration upon Breach of Agreement. In the event that the Company breaches any of its material obligations under this
Agreement, whether as a result of failure to make any payments when due (subject to the last sentence of this Section 4.01(b)), failure to honor any 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 

  
 14 

 
hereunder shall be accelerated and such obligations shall be calculated as if an Early Termination Notice had been delivered on the date of the breach 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 date of the breach; (ii) any Tax Benefit Payment agreed to by the Company and the TRA Party Representative as due and payable but unpaid as of
such date; and (iii) any Tax Benefit Payment due for the Taxable Year ending prior to, with or including such date (except to the extent that such amount is included in the Early Termination Payment). The parties agree that the failure to make
any material payment due pursuant to this Agreement within three 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 will 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 months of the date such payment is due. 

(c) Acceleration upon a Credit Event. In the event that either party becomes aware that an event described in clause (c) in the
definition of Credit Event exists with respect to the Company or any of its Subsidiaries, such party shall provide written notice to the other party (the “Credit Event Notice”). In the event that the Credit Event is not cured
within ten days of delivery of such Credit Event Notice or upon the occurrence of an event described in clauses (a) and (b) in the definition of Credit Event, all obligations hereunder shall be accelerated and such obligations shall be calculated as
if an Early Termination Notice had been delivered on the date the Credit Event 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 date of the Credit
Event; (ii) any Tax Benefit Payment agreed to by the Company and the TRA Party Representative as due and payable but unpaid as of such date; and (iii) any Tax Benefit Payment due for the Taxable Year ending prior to, with or including such date
(except to the extent that such amount is included in the Early Termination Payment).
 Section 4.02. Early Termination
Notice. If the Company chooses to exercise its right of early termination under Section 4.01(a) above, the Company shall deliver to the TRA Party Representative notice of the Company’s decision to exercise such right (the
“Early Termination Notice”). Upon the delivery of the Early Termination Notice or the occurrence of an event described in Section 4.01(b) or (c), the Company shall deliver a schedule (the “Early Termination
Schedule”) showing in reasonable detail the information required pursuant to Section 2.02 and the calculation of the Early Termination Payment. The delivery and finalization of such Early Termination Schedule shall be governed by
Section 2.03. 
 Section 4.03. Payment upon Early Termination.

(a) Timing of Payment. Within ten Business Days after the Early Termination Schedule becomes final and binding on the parties
hereto, the Company shall pay to each of the TRA Parties the Early Termination Payment. Such payment shall be made by wire transfer of immediately available funds to a bank account designated by the applicable TRA Party or as otherwise agreed
by the Company and such TRA Party. 
 (b) Amount of Payment. The “Early Termination Payment” with
respect to any TRA Party means an amount equal to such TRA Party’s Applicable Percentage of the present value, discounted at the Early Termination Rate as of such date, of all Tax Benefit Payments that

  
 15 

 
would be required to be paid by the Company to the TRA Parties beginning from the Early Termination Date applying the Valuation Assumptions. For purposes of calculating the present value
pursuant to this Section 4.03(b) of all Tax Benefit Payments that would be required to be paid, it shall be assumed that absent the Early Termination Notice all Tax Benefit Payments would be paid on the due date (without extensions) for filing the
Company’s Tax Return with respect to Taxes for each Taxable Year. 
 ARTICLE 5 

COMPANY OBLIGATIONS AND LATE PAYMENTS 

Section 5.01. Company Obligations.

(a) Notwithstanding any other provision of this Agreement to the contrary, upon the occurrence and during the continuance of any of the
bankruptcy-related events described in Section 7.1(f) of either Credit Agreement (or the equivalent bankruptcy default provisions of any senior debt documents that may from time to time replace any Credit Agreement), any Tax Benefit Payments and
Early Termination Payment required to be made by the Company to the TRA Parties 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 (i) the obligations
under each of the Credit Agreements (or under any senior debt documents that may from time to time replace any Credit Agreement) or any other obligations in respect of indebtedness, other than intercompany indebtedness, for borrowed money of the
Company and its Subsidiaries (“Senior Indebtedness”), (ii) payments in respect of letters of credit of the Company and its Subsidiaries, (iii) cash management obligations of the Company and its Subsidiaries and (iv) hedging
obligations entered into with the providers of the Senior Indebtedness or Affiliates thereof (collectively, the “Senior Obligations”) and shall rank pari passu in right of payment with all current or future unsecured
obligations of the Company that are not Senior Obligations. 
 (b) Without the prior written consent of the TRA Party Representative (not to
be unreasonably withheld, conditioned or delayed), the Company shall not enter into any agreement after the IPO Date if the terms of such agreement would be materially more restrictive than the Credit Agreements with respect to the ability of the
Company to make the Tax Benefit Payments or the Early Termination Payment under this Agreement. 
 (c) For so long as the Agreement remains
outstanding, without the prior written consent of the TRA Party Representative (not to be unreasonably withheld, conditioned or delayed), the Company shall not incur any indebtedness for borrowed money if, immediately after giving effect to such
incurrence and the application of proceeds therefrom, the Company’s Consolidated Net Leverage Ratio pro forma for such indebtedness exceeds 5.70 to 1.00, unless the incurrence of such indebtedness is permitted by each of the Credit Agreements
(including any senior debt documents that may from time to time replace any Credit Agreement to the extent that such senior debt document is no less restrictive with respect to the ability of the Company to incur indebtedness than the applicable
Credit Agreement replaced by such senior debt document). 
 Section 5.02. Late Payments by the Company. The amount of all or any
portion of any Tax Benefit Payment or Early Termination Payment required to be made by the Company to any TRA Party under this Agreement that is not made to such TRA Party when due under the terms of this Agreement shall be payable together with any
interest thereon, computed at the Default Rate and commencing from the date on which such payment was due and payable. 
 ARTICLE 6 

COMPANY TAX MATTERS; CONSISTENCY; COOPERATION 

Section 6.01. Participation in Company Tax Matters. Except as otherwise provided herein, the Company shall have full
responsibility for, and sole discretion over, all Tax matters concerning the Company Group, including, without limitation, the preparation, filing or amending of any Tax Return and defending, contesting or settling any issue pertaining to Taxes

  
 16 

 
(a “Tax Claim”), provided that the Company shall act in good faith in connection with its control of any matter which is reasonably expected to affect the TRA
Parties’ rights and obligations under this Agreement, provided further that the Company shall not enter into any settlement with respect to, or agree to concede, any Tax Claim that could have a material effect on the TRA Parties’
rights (including the right to receive payments) under this Agreement without the consent of the TRA Party Representative (not to be unreasonably withheld, conditioned or delayed). The Company shall notify the TRA Party Representative of, and
keep the TRA Party Representative reasonably informed with respect to, the portion of any audit of the Company Group by a Taxing Authority the outcome of which is reasonably expected to affect the TRA Parties’ rights and obligations under this
Agreement, and shall give the TRA Party Representative reasonable opportunity to provide information and participate (at its own expense) in the applicable portion of such audit.

Section 6.02. Consistency. Except upon the written advice of an Advisory Firm, the Company and the TRA Parties agree to report and
cause to be reported for all purposes, including U.S. and Canadian federal, state, provincial, local and non-U.S. and non-Canadian tax purposes and financial reporting purposes, all Tax-related items (including, without limitation, the Tax Benefit
Payments) in a manner consistent with that specified by the Company in any Schedule or statement required to be provided by or on behalf of the Company under this Agreement or under applicable Tax law. Any dispute concerning such advice shall be
subject to the Reconciliation Procedures; provided, however, that only the TRA Party Representative shall have the right to object to such advice pursuant to this Section 6.02. In the event that an Advisory Firm is replaced with
another firm acceptable to the Company and the TRA Party Representative pursuant to the definition of “Advisory Firm,” such replacement Advisory Firm shall be required to perform its services under this Agreement using procedures
and methodologies consistent with those used by the previous Advisory Firm, unless otherwise required by law (or the Company and the TRA Party Representative agree to the use of other procedures and methodologies). 

Section 6.03. Cooperation. Each of the Company, on the one hand, and the TRA Parties, on the other hand, shall (a) furnish to the
other party in a timely manner such information, documents and other materials as the other party may reasonably request for purposes of making or approving 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 relating to this Agreement; (b) make itself available to the other party and its representatives to provide explanations of documents and
materials and such other information as the requesting party or its representatives may reasonably request in connection with any of the matters described in clause (a) above; and (c) reasonably cooperate in connection with any such matter, and the
requesting party shall reimburse the other party for any reasonable third-party costs and expenses incurred pursuant to this Section 6.03.

(a) Provided that written notice is provided to the Company at least ten Business Days prior to an assignment or transfer, each TRA Party may
assign or transfer (including by way of a pledge, rehypothecation, grant of a participation in, or sale) this Agreement to any Person without the prior written consent of the Company or any other TRA Party. 

(b) No provision of this Agreement may be amended unless such amendment is approved in writing by the Company and the TRA Party
Representative. For the avoidance of doubt, any amendment of this Agreement that is approved in writing by the Company and the TRA Party Representative shall be binding upon the TRA Parties. 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. Notwithstanding anything contained herein to the contrary, the TRA Party Representative may, in its good faith discretion, amend Schedule A
without the consent of any other party hereto; provided that such amendment does not materially, adversely and disproportionately affect any TRA Party vis-à-vis any other TRA Party. 

  
 19 

 (c) 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 Company shall require and 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 Company, by written agreement, 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. 
 (d) The Company shall maintain at its offices a copy of each
notice of assignment or transfer received pursuant to Section 7.08(a) and a register for the recordation of the names, addresses and Applicable Percentages of the TRA Parties (the “Register”). The entries in the Register shall be
conclusive absent manifest error, and the Company and the TRA Parties shall treat each Person whose name is recorded in the Register pursuant to the terms hereof as a TRA Party hereunder for all purposes of this Agreement. Notwithstanding anything
contained herein to the contrary, no assignment or transfer shall be effective until such assignment or transfer has been recorded in the Register. 

Section 7.09. 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 7.10. Waiver of Jury Trial. EACH PARTY HERETO HEREBY
IRREVOCABLY WAIVES ALL RIGHT TO TRIAL BY JURY IN ANY LITIGATION, ACTION, PROCEEDING, CROSS-CLAIM, OR COUNTERCLAIM IN ANY COURT (WHETHER BASED ON CONTRACT, TORT, OR OTHERWISE) ARISING OUT OF, RELATING TO OR IN CONNECTION WITH (A) THIS AGREEMENT OR
THE VALIDITY, PERFORMANCE, INTERPRETATION, COLLECTION OR ENFORCEMENT HEREOF OR (B) THE ACTIONS OF THE PARTIES IN THE NEGOTIATION, AUTHORIZATION, EXECUTION, DELIVERY, ADMINISTRATION, PERFORMANCE OR ENFORCEMENT HEREOF. 

Section 7.11. Reconciliation. In the event that the Company and the TRA Party Representative are unable to resolve a disagreement
with respect to the matters governed by Section 2.03, Section 4.02 and Section 6.02 (which matters, for the avoidance of doubt, may include the calculations of any amounts set forth in any Schedule or Amended Schedule) within the relevant period
designated in this Agreement (a “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 in a nationally recognized accounting firm or a law firm (other than the Advisory Firm or the preparer of the Advisory Firm Letter), and the Expert shall not, and the firm that
employs the Expert shall not, have any material relationship with the Company or the TRA Party Representative or other actual or potential conflict of interest. If the parties are unable to agree on an Expert within 15 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, unless the parties mutually agree to extend such 15-day period. The Expert shall resolve any
matter relating to the Early Termination Schedule or an amendment thereto within thirty calendar days and shall resolve any matter relating to a Tax Benefit Schedule or an amendment thereto within fifteen 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 is due or any Tax
Return reflecting the subject of a disagreement is due, the undisputed amount shall be made on the date prescribed by this Agreement and such Tax Return may be filed as prepared by the Company, subject to adjustment (by an increase or decrease in
the amount of subsequent payments otherwise due under this Agreement) or amendment of such Tax Return upon resolution. The costs and expenses relating 

  
 20 

 
to the engagement of such Expert or amending any Tax Return shall be borne inversely based upon the relative success (in terms of percentages) of each party’s claims. For example, if the
final determination reflects a 60-40 compromise of the parties’ claims, the costs and expenses would be allocated 40% to the party whose claim was determined to be 60% successful and 60% to the party whose claim was determined to be 40%
successful. Any dispute as to whether a dispute is a Reconciliation Dispute within the meaning of this Section 7.11 shall be decided by the Expert. The Expert shall finally determine any Reconciliation Dispute and the determinations of the
Expert pursuant to this Section 7.11 shall be final and binding on the Company and all TRA Parties and may be entered and enforced in any court having jurisdiction. The determination of the Expert with respect to any dispute that is submitted to it
for determination pursuant to this Section 7.11 shall be based solely on presentations and materials provided by the parties hereto that are in accordance with the guidelines and procedures set forth in this Agreement (i.e., such determination shall
not be made on the basis of an independent review by the Expert). The Expert shall not assign a value to any Reconciliation Dispute that is greater than the greatest value for such item assigned by the Company, on the one hand, or the TRA Party
Representative, on the other hand, or less than the smallest value for such assigned by the Company, on the one hand, and the TRA Party Representative, on the other hand. 

Section 7.12. Withholding. The Company shall be entitled to deduct and withhold from any amount payable to any TRA Parties
pursuant to this Agreement such amounts as the Company is required to deduct and withhold under the Code or any provision of state, local or foreign tax law, with respect to entering into or making payments under this Agreement. To the extent
amounts are so withheld and paid over to the appropriate governmental authority by the Company, such withheld amounts shall be treated for all purposes of this Agreement as having been paid to the TRA Party in respect of whom such withholding was
made. The Company shall provide evidence of such payment to such TRA Party. To the extent the amount of any withholding hereunder cannot be finally determined until after the end of the taxable year in which the amount otherwise payable to
such TRA Parties pursuant to this Agreement is required to be paid, the Company shall be entitled to deduct and withhold the maximum amount of tax that, in the Company’s reasonable judgment, may be required to be remitted to the applicable
government authority with respect to such TRA Party, and after the applicable amount of withholding is finally determined, the Company shall promptly pay over any excess withheld amounts to such TRA Party. Notwithstanding the foregoing, if a
withholding obligation arises as a result of a Change of Control that causes the Company (or its successor) to become a non-U.S. Person, any amount payable to a TRA Party under this Agreement shall be increased such that after all required
deductions and withholdings have been made (including such deductions and withholdings applicable to additional sums payable under this sentence) the TRA Party receives an amount equal to the sum that it would have received had no such deductions or
withholdings been made. 
 Section 7.13. Confidentiality. 

(a) Each party shall maintain in strict confidence and shall not disclose to any third party (except to its Affiliates in connection with
performing any duties as necessary for the other party hereunder) any and all Confidential Information, except as may be necessary in order to comply with a requirement of Law, in which case the receiving party shall, if permissible, promptly notify
the disclosing party of any such requirement and such disclosing party shall be 

  
 21 

 
permitted to seek confidential treatment for such information; provided that any party hereto or its Affiliates may disclose the terms of this Agreement in any registration statement
relating to the IPO, provided further that the foregoing shall not prohibit any TRA Party from disclosing such terms and information to (i) its lenders, (ii) prospective purchasers of such TRA Party or its assets and such prospective
purchasers’ lenders, and (iii) legal counsel and other representatives of any of the foregoing. 
 (b) With respect to any such
Confidential Information, each of the parties hereto shall: (i) use the same degree of care in safeguarding the other party’s Confidential Information as it uses to safeguard its own information which is proprietary and/or treated as
confidential; and (ii) upon the discovery of any inadvertent disclosure or unauthorized use of the Confidential Information, or upon obtaining notice of such disclosure or use from the other party, take or cause to be taken all necessary actions to
prevent any further inadvertent disclosure or unauthorized use. 
 Section 7.14. Affiliated Corporations; Admission of the Company into a
Consolidated Group; Transfers of Corporate Assets.
 (a) If the Company or any member or members of the Company Group was, is or becomes
a member of an affiliated, combined, unitary or consolidated group of corporations that files a consolidated income tax return pursuant to Sections 1501 et seq. of the Code or any comparable provision of applicable state, local or non-U.S. Tax law
(a “Consolidated Return”): (i) the provisions of this Agreement relating to the Company shall be applied with respect to the group as a whole as of any date of determination; and (ii) Tax Benefit Payments shall be computed with
reference to the consolidated taxable income of the group as a whole. 
 (b) If an entity in the Company Group transfers one or more assets
to a corporation (or a Person classified as a corporation for U.S. income tax purposes) with which such entity does not file a consolidated Tax Return pursuant to Section 1501 of the Code (or any corresponding provision of state, local or non-U.S.
law), such entity, for purposes of calculating the amount of any Tax Benefit Payment (e.g., calculating the gross income of the Company’s affiliated or consolidated group and determining the Realized Tax Benefit) due hereunder, shall be treated
as having disposed of such asset in a fully taxable transaction on the date of such transfer. The consideration deemed to be received by such entity shall be determined as if such transfer occurred on an arm’s length basis with an unrelated
third party. 
 (c) If an entity in the Company Group transfers to a third party, directly or indirectly, stock of any Subsidiary as to
which the tax basis of such Subsidiary’s Covered Tax Assets exceeds the tax basis of the transferor entity’s stock in such Subsidiary in a taxable transaction to a third party, such tax basis difference shall be treated for purposes of
this Agreement as a Covered Tax Asset. 
 Section 7.15. Tax Treatment. The TRA Parties and the Company agree, solely for U.S. federal
income tax purposes, to treat (i) the Initial TRA as having been issued by the Company in satisfaction of indebtedness owed by the Company to the Initial TRA Party in an amount equal to the fair market value of the Initial TRA Party’s rights
under the Initial TRA, as jointly determined by the Company and the Initial TRA Party and (ii) a portion of each payment made under this Agreement as interest determined under Section 483 of the Code and any comparable provision of state or local
law. Each party shall file all Tax Returns in accordance with such treatment described in this section, unless otherwise required by a “determination” within the meaning of Section 1313 of the Code.

 Section 7.16. TRA Party Representative.

(a) Appointment. Without further action of any of the Company, the TRA Party Representative or any TRA Party, and as partial
consideration of the benefits conferred by this Agreement, the TRA Party Representative is hereby irrevocably constituted and appointed, with full power of substitution, to act in the name, place and stead of each TRA Party with respect to the
taking by the TRA Party Representative of any and all actions and the making of any decisions required or permitted to be taken by the TRA Party Representative under this Agreement. The power of attorney granted herein is coupled with an interest
and is irrevocable and may be delegated by the TRA Party Representative. No bond shall be required of the TRA Party Representative and it shall receive no compensation for its services. In the event that the TRA Party Representative disposes of its
entire interest in this Agreement, a majority of the remaining TRA Parties may elect another TRA Party to act as TRA Party Representative. In the event that the TRA Party Representative wishes to withdraw from its position under this Agreement as
TRA Party Representative, a majority of the TRA Parties, including the TRA Party Representative, may elect another TRA Party to act as TRA Party Representative. 

(b) Expenses. If at any time a TRA Party Representative shall incur out-of-pocket expenses in connection with the exercise of its
duties hereunder, upon written notice to the Company from the TRA Party Representative of documented costs and expenses (including fees and disbursements of counsel and accountants) incurred by the TRA Party Representative in connection with the
performance of its rights or obligations under this Agreement and the taking of any and all actions in connection therewith, the Company shall reduce any future payments (if any) due to the TRA Parties hereunder pro rata (based on their respective
Applicable Percentages) by the amount of such expenses which it shall instead remit directly to the requesting TRA Party Representative. In connection with the performance of its rights and obligations under this Agreement and the taking of any and
all actions in connection therewith, a TRA Party Representative shall not be required to expend any of its own funds (though, for the avoidance of doubt, it may do so at any time and from time to time in its sole discretion). 

(c) Limitation on Liability. The TRA Party Representative shall not be liable to any TRA Party for any act of the TRA Party
Representative arising out of or in connection with the acceptance or administration of its duties under this Agreement, except to the extent any liability, loss, damage, penalty, fine, cost or expense is actually incurred by such TRA Party as a
proximate result of the gross negligence, bad faith or willful misconduct of the TRA Party Representative (it being understood that any act done or omitted pursuant to the advice of legal counsel shall be conclusive evidence of such good faith and
reasonable judgment). The TRA Party Representative shall not be liable for, and shall be indemnified by the TRA Parties (on a several but not joint basis) for, any liability, loss, damage, penalty or fine incurred by the TRA Party Representative
(and any cost or expense incurred by the TRA Party Representative in connection therewith and herewith and not previously reimbursed pursuant to subsection (b) above) arising out of or in connection with the acceptance or administration of its
duties under this Agreement, except to the extent that any such liability, loss, damage, penalty, fine, cost or expense is the proximate result of the gross negligence, bad faith or willful misconduct of the TRA Party Representative (it being
understood that any act done or omitted pursuant to the advice of legal counsel shall be conclusive evidence of such good faith and reasonable judgment); provided, however, that in no event shall any TRA Party be obligated to indemnify
the TRA Party Representative hereunder for any liability, loss, damage, penalty, fine, cost or expense to the extent (and only to the extent) the aggregate amount of all liabilities, losses, damages, penalties, fines, costs and expenses indemnified
by such TRA Party hereunder is or would be in excess of the aggregate payments under this Agreement actually remitted to such TRA Parties. 

(d) Actions of the TRA Party Representative. A decision, act, consent or instruction of the TRA Party Representative shall
constitute a decision of all TRA Parties and shall be final, binding and conclusive upon each TRA Party, and the Company may rely upon any decision, act, 

  
 23 

 
consent or instruction of the TRA Party Representative as being the decision, act, consent or instruction of each TRA Party. The Company is hereby relieved from any liability to any person for
any acts done by the Company in accordance with any such decision, act, consent or instruction of the TRA Party Representative, including, without limitation, any action taken by the Company in its dealings with the TRA Party Representative pursuant
to and consistent with the terms of this Agreement (including, without limitation, complying with expense reimbursement requests pursuant to Section 7.16(b)). Each TRA Party hereby agrees that the TRA Party Representative may, at any time and in its
sole discretion, elect to enter into a transaction which is likely to result in the assignment, in whole or in part, of this Agreement to a Person (upon such election, an “Approved Assignment”), and each such TRA Party will raise no
objections against such Approved Assignment, regardless of the consideration (if any) being paid in such Approved Assignment, so long as such Approved Assignment does not materially and adversely impact such TRA Parties in a manner materially
adverse to the other TRA Parties. Each TRA Party will take all actions requested by the TRA Party Representative in connection with the consummation of an Approved Assignment, including the execution of all agreements, documents and instruments
in connection therewith requested by the TRA Party Representative of such TRA Party. Upon the consummation of the Approved Assignment, each TRA Party will receive its Applicable Percentage of such consideration, if any, relating to such
Approved Assignment. Each TRA Party will bear its Applicable Percentage of the costs of any Approved Assignment to the extent such costs are incurred for the benefit of all TRA Parties. 

(e) Involvement in Company Determinations. In the event that any determination must be made under this Agreement by the TRA Party
Representative or any dispute arises hereunder, should any representatives of the TRA Party Representative or its Affiliates then be serving on the Board, such directors shall be excluded from all deliberations and actions of the Board related to
such determination or dispute.
