Benefit Payment (if any) for a Covered Taxable Year and items with respect to a Tax Schedule may have become final under Section 2.01(c), such items shall be revised to the extent necessary to reflect (i) a Determination,
(ii) material inaccuracies in the original computation as a result of factual information that was not previously taken into account, (iii) a material change attributable to a carryback or carryforward of a loss or other tax item,
(iv) a material change attributable to an amended Tax Return filed for such Covered Taxable Year or (v) to comply with the National Expert’s determination under the Reconciliation Procedures (such Schedules, a “Revised
Schedule”). The Company shall deliver any Revised Schedule to the Holders’ Representative within 30 calendar days of any of the foregoing events described in clauses (i) through (v) occurring. 

(e) Applicable Principles. It is the intention of the parties for the Company to pay the Holders 85% of the overall net additional
Income Taxes that the Company Group (or any member thereof) would have been required to pay on Tax Returns that have actually been filed but for the use of any Pre-IPO and IPO-Related Tax Assets, and this Agreement shall be interpreted in accordance
with such intention. Carryovers or carrybacks of any tax item shall be considered to be subject to the rules of the Code (or any successor Income Tax statute) and the Treasury Regulations (and any relevant provisions of state, local or Canadian tax
law) governing the use, limitation and expiration of carryovers or carrybacks of the relevant type, provided, however, that Pre-IPO and IPO-Related 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, and, for purposes of determining the Realized Tax Benefit for any Taxable Year, each Taxable Entity shall be assumed (a) 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 Pre-IPO and IPO-Related Tax Asset that is
permitted to be so carried back, carried forward or utilized; provided that for the avoidance of doubt, in order to properly implement the intention of the parties described in this clause (a), with respect to any SR&ED Credits arising in
such Taxable Year, notwithstanding that Canadian tax law provides that such current SR&ED Credits shall be utilized only after carrying forward to such Taxable Year any prior year SR&ED Credits, such prior year credits shall be considered as
utilized after any current year credits are considered as utilized, (b) to utilize any available Pre-IPO and IPO-Related Tax Asset that is permitted (or, for the avoidance of doubt, that would be so permitted but for an Other Tax Asset) to be
carried back, carried forward or utilized in such Taxable Year before utilizing any Other Tax Asset, and (c) to utilize any Pre-IPO and IPO-Related Tax Asset in the first Taxable Year in which such Pre-IPO and IPO-Related Tax Asset is permitted
to be utilized; provided, further, however, that, notwithstanding any other provision herein, the Company and the Holders’ Representative shall, acting reasonably, together determine the extent to which a Pre-IPO and IPO-Related
Tax Asset can be carried back or carried forward to a Straddle Year or any portion thereof. If a carryover or carryback of any Tax Attribute includes a portion that is attributable to the Pre-IPO and IPO-Related Tax Assets and another portion that
is not, and such other portion originated in a taxable period that preceded the origination of the portion attributable to the Pre-IPO and IPO-Related Tax Assets, the Company shall be assumed to utilize the portion attributable to


  
 14 








 
the Pre-IPO and IPO-Related Tax Assets before utilizing such other portion. In the event of a Section 382 Ownership Change, all amounts payable by the Company under this Agreement, including
any Tax Benefit Payments, shall, under all circumstances, continue to be calculated in all respects as if such Section 382 Ownership Change had not occurred. 

ARTICLE III 
 TAX BENEFIT PAYMENTS

 SECTION 3.01. Payments. 

(a) Subject to Section 3.05, within 5 Business Days of the Tax Schedule for any Covered Taxable Year becoming final under
Section 2.01(c), the Company shall pay to the Holders’ Representative, or to a paying agent designated by the Holders’ Representative, on behalf of the Holders an amount equal to the Tax Benefit Payment. Each Holder shall be entitled
to receive an amount equal to the Tax Benefit Payment multiplied by the Holder’s Sharing Percentage. Each Tax Benefit Payment shall be made by wire transfer of immediately available funds to the bank account of the Holders’ Representative
previously designated to the Company. 
 (b) A “Tax Benefit Payment” shall equal, with respect to any Covered Taxable Year,
the amount of Covered Tax Benefits, if any, for the Covered Taxable Year, increased by: 
 (1) the interest calculated at the
Agreed Rate from the due date (without extensions) for filing the U.S. federal income Tax Return (the “Filing Date”) with respect to Income Taxes for such Covered Taxable Year until the Payment Date; and 

(2) any increase in a Covered Tax Benefit that has become final under Section 2.01(d); 

provided, however, that the amounts described in Section 3.01(b)(2) above shall not be taken into account in determining a Tax Benefit
Payment attributable to any Covered Taxable Year to the extent of such amounts that were taken into account in determining any Tax Benefit Payment for a preceding Covered Taxable Year. 

SECTION 3.02. Offsets and Indemnification. 

(a) In the event that a Tax Schedule is revised pursuant to Section 2.01(d) for any Covered Taxable Year reflecting a decrease in the Tax
Benefit Payment for such year and payments have previously been made based on the higher Tax Benefit Payment (such excess, an “Excess Payment”), any amount that would otherwise be due to the Holders at any subsequent time under
Section 3.01(b) (but not, for avoidance of doubt, under Section 3.05) shall be offset and reduced (but not below zero) until such Excess Payment has been repaid. For the avoidance of doubt, if future payments are insufficient to repay any
Excess Payment, the Holders shall have no obligation to repay such Excess Payment. 

  
 15 








 (b) Within 5 Business Days of the delivery of a Revised Schedule to the Holders’
Representative for any Covered Taxable Year, the Company shall pay to the Holders’ Representative on behalf of the Holders an amount equal to the excess, if any, of (x) the amount each Holder is entitled to receive under this Agreement in
respect of the relevant Covered Taxable Year (based on such Revised Schedule) over (y) the cumulative amount paid in respect of such Covered Taxable Year pursuant to this Agreement. 

SECTION 3.03. No Duplicative Payments. No duplicative payment of any amount (including interest) will be required under this Agreement.

 SECTION 3.04. Pro Rata Payments. If for any reason the Company does not fully satisfy its payment obligations to make all Tax
Benefit Payments due under this Agreement in respect of a particular Covered Taxable Year, then the Holders agree that the Holders’ Representative shall pay the same proportion of each Tax Benefit Payment due to each Holder in respect of such
Covered Taxable Year, without favoring one Holder over the other. 
 SECTION 3.05. Special Rule for Award Holders and Compensatory
Payments. Notwithstanding anything herein to the contrary, except as otherwise set forth in Section 6.01, no Compensatory Payment shall be made other than in a single lump-sum payment on the first date to occur as set forth in
Section 3.05(a), (b) or (c), as applicable. 
 (a) Except as provided in Section 3.05(b) and (c), any Compensatory Payment
shall be made by the Company to each Award Holder through the applicable Company or Subsidiary payroll process on the Compensatory Payment Settlement Date. The Compensatory Payment shall be equal to the sum of (i) all Compensatory Payments
that, but for this Section 3.05, would have been made to such Award Holder prior to the Compensatory Payment Settlement Date, plus interest (at a rate of 120% of the applicable federal long-term rate (as prescribed under Section 1274(d) of
the Code)) on each such Compensatory Payment from the date such payment would have been made (absent this Section 3.05) through the Compensatory Payment Settlement Date, (ii) an amount equal to the good-faith estimate of the Compensation
Committee of the present value, discounted at the Early Termination Rate as of the Compensatory Payment Settlement Date, of all Compensatory Payments that would have been made hereunder (absent this Section 3.05) to the applicable Award Holder
subsequent to the Compensatory Payment Settlement Date. For purposes of estimating the present value of the Compensatory Payments described in clause (ii) of this Section 3.05(a), the Compensation Committee may, in its sole discretion,
decide to apply the Valuation Assumptions. In the event that the Valuation Assumptions are applied in the circumstances described in the foregoing sentence, then each reference in the definition of Valuation Assumptions to “Early


  
 16 








 
Termination Date” shall be replaced with “Compensatory Payment Settlement Date.” All determinations and calculations with respect to the Compensatory Payment shall be final and not
subject to challenge or review, including, without limitation, pursuant to Section 8.13 hereof. 
 (b) In the event of a Change of
Control that constitutes a “change in control event” within the meaning of Section 409A prior to the Compensatory Payment Settlement Date, the Compensatory Payment shall be made on the date of such Change of Control, calculated and
paid in accordance with Section 3.05(a), but substituting the date of the Change of Control for the Compensatory Payment Settlement Date. 

(c) At its option, the Company, after obtaining the prior written consent of the Holders’ Representative, may make the Compensatory
Payment prior to the Compensatory Payment Settlement Date, calculated and paid in accordance with Section 3.05(a), but substituting such earlier payment date for the Compensatory Payment Settlement Date, but only to the extent such earlier
payment date is permitted by and in compliance with Treasury Regulation Section 1.409A-3(j)(4). 
 (d) For purposes of determining
amounts that would be payable pursuant to Article II, this Article III (other than this Section 3.05) and Article V in respect of Sharing Percentages, all determinations shall be made as if all Compensatory Payments that would, absent this
Section 3.05, have been made prior to the date of the applicable determination had in fact been made on the dates they would have been made absent this Section 3.05. 

ARTICLE IV 
 CHANGE NOTICE 

SECTION 4.01. 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 or any Taxing Authority with respect to the Tax treatment of any Pre-IPO and IPO-Related Tax Asset (a “Change Notice”), which, if sustained, would result in (i) a
reduction in the amount of Realized Tax Benefit with respect to a Covered Taxable Year preceding the taxable year in which the Change Notice is received or (ii) a reduction in the amount of Tax Benefit Payments the Company will be required to
pay to the Holders’ Representative with respect to Covered Taxable Years after and including the taxable year in which the Change Notice is received, prompt written notice shall be given to the Holders’ Representative.

 ARTICLE V 

TERMINATION 
 SECTION 5.01.
Early Termination, Change of Control, Breach of Agreement and Divestiture. 
 (a) The Company may terminate this Agreement with the
approval by a majority of the directors of the Company (“Elective Early Termination”) by paying to the Holders the Early Termination Payment as of the date of the Early Termination Notice (the “Early Termination
Date”). Upon payment of the Early Termination Payment by the Company pursuant to an Elective Early Termination, the Company shall have no further payment obligations under this Agreement, other than for any (a) Tax Benefit Payment
agreed to by the Company and the Holders as due and payable but unpaid as of the Early Termination Date and (b) any Tax Benefit Payment due for the Covered Taxable Year ending with or including the date of the Early Termination Date (except to
the extent that the amount described in clause (a) or (b) is included in the Early Termination Payment). 
 (b) 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 effective date of such Change of Control and shall include, but not be limited to,
(a) the Early Termination Payment calculated as if an Early Termination Notice had been delivered on such date, (b) any Tax Benefit Payment agreed to by the Company and the Holders as due and payable but unpaid as of the Early Termination
Date and (c) any Tax Benefit Payment due for the Covered Taxable Year ending with or including the Early Termination Date (except to the extent that the amount described in clause (b) or (c) is included in the Early Termination
Payment). 
 (c) In the event that the Company breaches any of its material obligations under this Agreement, whether as a result of failure
to make any material payment when due, failure to honor any other material obligation required hereunder or by operation of law as a result of the rejection of this Agreement in a case commenced under the Bankruptcy Code or otherwise, then all
obligations hereunder shall be accelerated and such obligations shall be calculated as if an Early Termination Notice had been delivered on the date of such breach and shall include, but shall not be limited to, (1) the Early Termination
Payment calculated as if an Early Termination Notice had been delivered on the date of a breach, (2) any Tax Benefit Payment agreed to by the Company and the Holders as due and payable but unpaid as of the date of a breach, and (3) any Tax
Benefit Payment due for the Taxable Year ending with or including the date of a breach. Notwithstanding the foregoing, in the event that the Company breaches this Agreement, the Holders shall be entitled to elect to receive the amounts set forth in
clauses (1), (2) and (3) above or to seek specific performance of the terms hereof. The parties agree that the failure to make any payment due pursuant to this Agreement within three 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. In the case of a breach of a material obligation other than an obligation to make a payment, the Company will not be considered to have breached such obligation for purposes of this Section 5.01(c)
until the Holders have provided written notice to the Company that the Company has breached its material obligations and so long as such breach is cured within five Business Days of the delivery of such notice to the Company, the Company shall not
be in breach of its obligations under this Agreement. 

  
 18 








 (d) In the event of a Divestiture, the Company shall pay to the Holders the Early Termination
Payment in respect of such Divestiture and such payment shall be calculated as if an Early Termination Notice had been delivered on the effective date of such Divestiture. 

(e) The Company and the Holders hereby acknowledge that, as of the date of this Agreement, the aggregate value of the Tax Benefit Payments
cannot reasonably be ascertained for U.S. federal income tax or other applicable Tax purposes. 
 SECTION 5.02. Early Termination
Notice. In the event of an Elective Early Termination, the Company shall deliver to the Holders’ Representative a notice (the “Early Termination Notice”) specifying the Company’s intention to exercise such right and
showing in reasonable detail its calculation of the Early Termination Payment (the “Proposed Early Termination Payment”). At the time the Company delivers the Early Termination Notice to the Holders’ Representative, the Company
shall deliver to the Holders’ Representative (i) a schedule showing, in reasonable detail, the computation of the Proposed Early Termination Payment (the “Early Termination Tax Schedule”), (ii) any work papers and
valuation reports relating to the computation of the Proposed Early Termination Payment and (iii) any National Expert report with respect to such Early Termination Tax Schedule, work papers and valuation reports. The Company shall also provide
the Holders’ Representative and its advisors reasonable access during normal business hours at no cost to the appropriate representatives at the Company and its Subsidiaries in connection with its review of the Early Termination Tax Schedule,
work papers and reports. Within 30 calendar days after receiving such calculation, the Holders’ Representative shall notify the Company whether it agrees to or objects to the Proposed Early Termination Payment. The Proposed Early Termination
Payment shall become final and binding on the parties if the Holders’ Representative agrees in writing to the value of the Proposed Early Termination Payment within such 30 day period (or such shorter period as may be mutually agreed in writing
by the parties). If the Holders’ Representative objects, and the Holders’ Representative and the Company, for any reason, cannot agree upon the value of the Early Termination Payment within 15 calendar days following the Company’s
receipt of the Holders’ Representative objection, the Company and the Holders shall employ the Reconciliation Procedures as described in Section 8.13 of this Agreement. For the avoidance of doubt, the Company shall have no obligation to
request early termination under Section 5.01. 
 SECTION 5.03. Payment upon Early Termination. Within 10 calendar days of an
agreement between the Holders and the Company as to the value of the Early Termination Payment, the Company shall pay to the Holders an amount equal to the Early Termination Payment. Such payment shall be made by wire transfer of immediately
available funds to a bank account designated by the Holders. 

  
 19 








 SECTION 5.04. Compensatory Payments. Notwithstanding anything herein to the contrary, this
Article V shall not apply to any Compensatory Payments, the payment of which shall be as set forth in Sections 3.05 hereof. 
 ARTICLE VI

 SUBORDINATION AND LATE PAYMENTS 

SECTION 6.01. Subordination. Notwithstanding anything to the contrary provided herein, if, at the time any payments are required to be
made by the Company under this Agreement, (a) the Company is not permitted, pursuant to the terms of its outstanding indebtedness, to pay such amounts, (b) (i) the Company does not have the cash on hand or availability under any
revolving credit agreement to pay such amounts or payment of such dividends would give rise to a material adverse effect or a default under any such agreement, and (ii) no Subsidiary of the Company is permitted, pursuant to the terms of its
outstanding indebtedness or other applicable law, to pay dividends to the Company to allow it to pay such amounts, or (c) payments of such amounts would violate applicable law then, in each case, the Company shall, by notice to the Holder, be
permitted to defer the payment of such amounts until the condition described in clause (a), (b) or (c) is no longer applicable, in which case such amounts, including any amounts payable under Section 5.01(b) and (c), together with
accrued and unpaid interest thereon as described in the immediately following sentence shall become due and payable immediately. If the Company defers the payment of any such amounts pursuant to the foregoing sentence, such amounts shall accrue
interest at the Agreed Rate, from the date that such amounts originally became due and owing pursuant to the terms hereof to the date that such amounts were paid. Notwithstanding the foregoing, if any Compensatory Payment would be subject to tax,
penalty or interest under Section 409A if paid pursuant to the immediately preceding sentence, such Compensatory Payment shall not be paid as set forth therein but shall instead be paid as set forth in Section 3.05(a), (b) or (c), as
applicable, or otherwise in accordance with Section 409A. The Company agrees to take commercially reasonable actions to cause its direct and indirect Subsidiaries to pay dividends (including, to the extent commercially reasonable, access any
revolving credit facility or other source of liquidity to facilitate the payment of such dividends), to the extent consistent with the terms of their outstanding indebtedness and any applicable law, to the extent necessary to make payments
hereunder. 
 SECTION 6.02. Late Payments. The amount of all or any portion of a payment not made 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 VII 

NO DISPUTES; CONSISTENCY; COOPERATION 

SECTION 7.01. Holders’ Participation in Company Tax Matters. Except as otherwise provided herein, the Company shall have full
responsibility for, and sole discretion over, all Income 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
Income Taxes. Notwithstanding the foregoing, the Company shall notify the Holders’ Representative of, and keep the Holders’ Representative reasonably informed with respect to, and the Holders’ Representative shall have the right to
participate in (at its own expense) and monitor (but not control) the portion of any audit of the Company Group by the applicable Taxing Authority the outcome of which is reasonably expected to affect the Holders’ rights under this Agreement.
The Company shall provide to the Holders’ Representative reasonable opportunity to provide information and other input to the Company and its advisors concerning the conduct of any such portion of such audits.

manner consistent with that specified by the Company in any Schedule required to be provided by or on behalf of the Company under this Agreement. Any dispute concerning the accounting or law firm’s advice shall be subject to the terms of
Section 8.13. 
 SECTION 7.03. Cooperation. Each of the Company and the Holders (through the Holders’ Representative) 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, (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 7.03.

SECTION 8.02. Amendments and Modifications. Except as otherwise provided herein, no amendment, modification, or variation of any
provision of this Agreement shall in any event be effective unless the same shall be in writing and signed by each of the parties hereto. 

SECTION 8.03. No Waiver. The failure of any party hereto, at any time or times, to require strict performance by the other party hereto
of any provision of this Agreement shall not waive, affect or diminish any right of such party thereafter to demand strict compliance and performance herewith. Any suspension or waiver of any provision of this Agreement shall not suspend, waive or
affect any other provision of this Agreement whether the same is prior or subsequent thereto. None of the undertakings, agreements and covenants of any party hereto contained in or contemplated by any other provision of this Agreement shall be
deemed to have been suspended or waived by any other party hereto, unless such waiver or suspension is by an instrument in writing signed by an officer of or other authorized employee of such party and directed to any other party hereto specifying
such suspension or waiver. 
 SECTION 8.04. Successors and Assigns; No Third Party Beneficiaries. 

(a) The Holders’ Representative may not assign its rights and obligations in its capacity as Holders’ Representative under this
Agreement to any Person without the prior written consent of the Company; provided, however, that the Holders’ Representative may assign its rights and obligations in its capacity as Holders’ Representative
under this Agreement to any of its Affiliates, 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
Company agreeing to be become the “Holders’ Representative” for all purposes of this Agreement. 

  
 22 








 (b) No Holder may assign its rights and obligations under this Agreement without the prior
written consent of the Company and the Holders’ Representative; provided, however, that the rights hereunder may be freely assigned by any Sponsor Stockholder to (i) any Affiliate of such Sponsor Stockholder, (ii) another Sponsor
Stockholder or (iii) any Permitted Transferee. The Company must receive notice of any proposed assignment no later than 5 days prior to the effective date of such assignment and any transferee must, concurrently with the transfer, execute and
deliver a joinder to this Agreement, in the form of Exhibit A, agreeing to become the “Holder” for all purposes of this Agreement with respect to the transferred interest and assume all obligations of its transferor. Notwithstanding the
foregoing, an Award Holder shall not be permitted to assign its rights and obligations under this Agreement in respect of an Award to the extent such assignment would give rise to tax, penalty or interest under Section 409A, as determined by
the Compensation Committee. A Holder, other than an Award Holder in respect of an Award, may pledge some or all of its rights, interests or entitlements under this Agreement to any U.S. money center bank in connection with a bona fide loan or other
indebtedness. 
 (c) If the Company or any of its successors or assigns (i) shall consolidate with or merge into any other corporation
or entity and shall not be the continuing or surviving corporation or entity of such consolidation or merger or (ii) shall transfer all or substantially all of its properties and assets to any individual, corporation or other entity, then and
in each such case proper provisions shall be made so that the successors and assigns of the Company shall assume all of the obligations set forth in this Agreement, including, for the avoidance of doubt, any obligations that are outstanding under
this Agreement at the time of such consolidation, merger or transfer. 
 (d) This Agreement shall be binding upon and inure to the benefit of
all of the parties and their respective successors and permitted assigns, including, for the avoidance of doubt, any successor of the Company. The terms and provisions of this Agreement are for the purpose of defining the relative rights and
obligations of the parties hereto with respect to the transactions contemplated hereby and no Person shall be a third party beneficiary of any of the terms and provisions of this Agreement. 

SECTION 8.05. Entire Agreement. This Agreement constitutes the entire agreement, and supersedes all prior agreements, understandings,
representations and warranties, both written and oral, between the parties with respect to the subject matter hereof and thereof. 
 SECTION
8.06. Severability. Wherever possible, each provision of this Agreement shall be interpreted in such a manner as to be effective and valid under applicable law, but if any provision of this Agreement shall be prohibited by or invalid under
applicable law, the provisions of this Agreement shall be deemed to be severable but only to the extent consistent with economic and other purposes of this Agreement. 

  
 23 








 SECTION 8.07. Consent to Jurisdiction. Each party agrees that it shall bring any action,
suit, demand or proceeding (including counterclaims) in respect of any claim arising out of or related to this Agreement or the transactions contemplated hereby, exclusively, in the Delaware Court of Chancery or, if unavailable, the United States
District Court for the District of Delaware, in each case, sitting in the City of Wilmington, Delaware (as applicable, the “Chosen Courts”), and solely in connection with claims arising under this Agreement or the transactions
contemplated hereby (i) irrevocably submits to the exclusive jurisdiction of the Chosen Courts, (ii) waives any objection to laying venue in any such action, suit, demand or proceeding in the Chosen Courts, (iii) waives any objection
that the Chosen Courts are an inconvenient forum or do not have jurisdiction over any party and (iv) agrees that service of process upon such party in any such action, suit, demand or proceeding shall be effective if notice is given in
accordance with Section 8.01. 
 SECTION 8.08. Waiver of Jury Trial. Each of the parties hereto hereby irrevocably waives any
and all right to trial by jury in any legal proceeding arising out of or related to this Agreement or the transactions contemplated hereby. 

SECTION 8.09. Governing Law. This Agreement (and all claims, controversies and causes of action, whether in contract, tort or
otherwise) and the rights and obligations of the parties hereunder shall be governed by, and construed, interpreted and enforced in accordance with, the laws of the State of Delaware, without regard to the conflicts of law rules of such State that
would result in the application of the laws of any other State. 
 SECTION 8.10. Counterparts. This Agreement may be executed in
multiple counterparts, each of which when so executed and delivered shall be an original, and all of which when taken together shall constitute one and the same instrument. 

SECTION 8.11. Interpretation. Any references to an agreement or organizational document herein shall mean such agreement or
organizational document, as may be amended, modified and/or supplemented (and/or as any provision thereunder may be waived) from time to time in accordance with its terms. 

SECTION 8.12. Headings. The descriptive headings of the several Articles and Sections contained in this Agreement are and shall be
without substantive meaning or content of any kind whatsoever and are not a part of the agreement between the parties hereto. 
 SECTION
8.13. Reconciliation. In the event that the Company and the Holders’ Representative are unable to resolve a disagreement within the relevant period designated in this Agreement, the matter shall be submitted for determination to a
nationally recognized expert in the particular area of disagreement employed by a nationally recognized accounting firm or a law firm, which expert is mutually acceptable to all parties (the “National Expert”). 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, such payment shall be made on the date prescribed by this Agreement in the amount proposed by the Company and
such Tax Return shall be filed 

  
 24 








 
as prepared by the Company, subject to adjustment or amendment upon resolution. The costs and expenses related to the engagement of the National Expert or amending any Tax Return shall be borne
by the Company, except as provided in the next sentence. Each of the Company and the Holders shall bear their own costs and expenses of such proceeding. Any dispute as to whether a dispute is subject to the Reconciliation Procedures under this
Agreement shall be decided by the National Expert. The determinations of the National Expert pursuant to this Section 8.13 shall be binding on the Company, its Subsidiaries and the applicable Holder absent manifest error and may be entered and
enforced in any Chosen Court. 
 SECTION 8.14. Withholding. The Company and its Subsidiaries shall be entitled to deduct and withhold
from any payment payable pursuant to this Agreement such amounts as the Company or Subsidiary is required to deduct and withhold with respect to the making of such payment under the Code, the Treasury Regulations, or any provision of state, local or
foreign tax law. To the extent that amounts are so withheld and paid over to the appropriate Taxing Authority by the Company or Subsidiary, such withheld amounts shall be treated for all purposes of this Agreement as having been paid to the
applicable Holder. The Company shall provide evidence of such payments to the Holders other than Award Holders through the Holders’ Representative, to the extent that such evidence is available, and directly to the Award Holders consistent with
the payroll processes of the Company or Subsidiary. 
 SECTION 8.15. Admission of the Company into a Consolidated Group. 

(a) If the Company is or becomes a member of an affiliated or consolidated group of corporations that files a consolidated income tax return
pursuant to Sections 1501 et seq. of the Code or any corresponding provisions of state, local or foreign law (other than if the Company becomes a member of such group as a result of a change in control, in which case the provisions of Article IV
shall control), then: (a) the provisions of this Agreement shall be applied with respect to the group as a whole; and (b) Tax Benefit Payments and other applicable items hereunder shall be computed with reference to the consolidated
taxable income of the group as a whole. 
 (b) If any Person the income of which is included in the income of the Company’s affiliated
or consolidated group transfers one or more assets to a corporation or any Person treated as such for Tax purposes with which such entity does not file a consolidated tax return pursuant to Section 1501 et seq. of the Code or any corresponding
provisions of state, local or foreign law, then 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, such Person shall be treated as having disposed of such asset in a fully taxable transaction on the date of such contribution. The consideration deemed to be received by such entity shall be determined as if such transfer occurred on
an arm’s-length basis with an unrelated third party. 

  
 25 








 SECTION 8.16. Appointment of Holders’ Representative. 

(a) Without further action of the Company, the Holders’ Representative or the Holders, and as partial consideration of the benefits
conferred by this Agreement, the Holders’ Representative is hereby irrevocably constituted and appointed, with full power of substitution, to act in the name, place and stead of each Holder with respect to the taking by the Holders’
Representative of any and all actions and the making of any decisions required or permitted to be taken by the Holders’ Representative under this Agreement. The power of attorney granted herein is coupled with an interest and is
irrevocable and may be delegated by the Holders’ Representative. No bond shall be required of the Holders’ Representative, and the Holders’ Representative shall receive no compensation for its services. 

(b) If at any time the Holders’ Representative shall incur out of pocket expenses in connection with the exercise of its duties hereunder,
the Holders’ Representative shall be entitled to reduce any future payments (if any) due to Holders hereunder pro rata (based on their respective Sharing Percentages to which such costs and expenses relate) by the amount of such costs and
expenses. In connection with the performance of its rights and obligations under this Agreement and the taking of any and all actions in connection therewith, the Holders’ 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) The Holders’
Representative shall not be liable to any Holder for any act of the Holders’ 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 Holder as a proximate result of the gross negligence, bad faith or willful misconduct of the Holders’ Representative (it being understood that any act done or omitted pursuant
to the advice of legal counsel shall be conclusive evidence of good faith and reasonable judgment). The Holders’ Representative shall not be liable for, and shall be indemnified by the Holders (on a several but not joint basis) for, any
liability, loss, damage, penalty or fine incurred by the Holders’ Representative (and any cost or expense incurred by the Holders’ 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 Holders’ Representative (it being understood that any act done or omitted pursuant to the advice of legal counsel shall be conclusive evidence of good faith and reasonable judgment);
provided, however, in no event shall any Holder be obligated to indemnify the Holders’ Representative hereunder for any liability, loss, damage, penalty, fine, cost or expense to the extent (and only to the extent) that the aggregate
amount of all liabilities, losses, damages, penalties, fines, costs and expenses indemnified by such Holder hereunder is or would be in excess of the aggregate payments under this Agreement actually remitted to such Holder. Each Holder’s
receipt of any and all benefits to which such Holder is entitled under this Agreement, if any, is conditioned upon and subject to such Holder’s acceptance of all obligations, including the obligations of this Section 8.16(c), applicable to
such Holder under this Agreement. 

  
 26 








 (d) Any decision, act, consent or instruction of the Holders’ Representative shall
constitute a decision of all Holders and shall be final, binding and conclusive upon each Holder, and the Company may rely upon any decision, act, consent or instruction of the Holders’ Representative as being the decision, act, consent or
instruction of each Holder. 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 Holders’ Representative. 

SECTION 8.17. Section 409A. 

(a) It is the intent of the Company that all payments and benefits under this Agreement comply with or be exempt from Section 409A, and,
accordingly, to the maximum extent permitted, this Agreement shall be interpreted to be exempt from Section 409A or in compliance therewith, as applicable. Nothing contained herein shall constitute any representation or warranty by the Company
regarding compliance with Section 409A. The Company shall have no obligation to take any action to prevent the assessment of any additional tax, interest or penalties under Section 409A on any Award Holder or any other person, and the
Company, its Subsidiaries, its Affiliates, and each of their respective employees and representatives shall have no liability to any Award Holder or any other person with respect thereto. 

(b) With respect to amounts deemed to be “nonqualified deferred compensation” subject to Section 409A: (i) all expenses or
other reimbursements as provided herein shall be made on or prior to the last day of the taxable year following the taxable year in which such expenses were incurred; (ii) no such reimbursement or expenses eligible for reimbursement in any
taxable year shall in any way affect the expenses eligible for reimbursement in any other taxable year; and (iii) the right to reimbursement or in-kind benefits shall not be subject to liquidation or exchange for another benefit. 

SECTION 8.18. Tax Treatment. Each Holder (other than an Award Holder in respect of an Award), the Holders’ Representative and the
Company agree that by entering into this Agreement, each Holder is receiving a distribution in an amount equal to the fair market value of its rights under this Agreement, as jointly determined by the Company and the Holders’ Representative,
and that such distribution is subject to Section 301 of the Code for U.S. federal income tax purposes and any similar or comparable state law provision for state tax purposes. Each such party shall file all Tax Returns in accordance with such
treatment described in the previous sentence, unless otherwise required by a “determination” within the meaning of Section 1313 of the Code.
