any Tax Item is adjusted or redetermined. 
 (nn) “Separate Return” shall mean any Tax Return that is not a Joint Return.

 (oo) “Separate Return Tax Liability” means an amount equal to the hypothetical federal, state or local Tax liability
that the members of the Company Group included in a Joint Return filed in any Tax jurisdiction would have incurred if they had filed a consolidated return, combined return (including nexus combination, domestic combination, line of business
combination or any other form of combination), unitary return, or separate return, as the case may be, separate from the members of the Embraer U.S. Group, for the relevant Tax period in such Tax jurisdiction (based upon the assumption that such
members of the Company Group were required to file in such Tax jurisdiction), and their income was taxable at the highest corporate tax rate in effect for such period in such Tax jurisdiction; provided, however, that (1) the
Separate Return Tax Liability shall be computed by Embraer U.S. using such methods, conventions, practices, principles, positions, and elections (for example, the election to deduct or credit foreign Taxes) as are consistent with the methods,
conventions, practices, principles, positions and elections that are used by Embraer U.S. or Parent, as the case may be, in preparing the applicable Joint Return, and by taking into account only those Tax Assets of the Company Group (or other Tax
Items of loss, deduction or credit of the Company Group) that are included in and used in the applicable Joint Return to create any Tax Benefit (without regard to whether the Company Group could have used such Tax Assets or Tax Items on its
hypothetical separate return), (2) the Consolidated Return Regulations (or any similar provisions of state or local Tax Law) and the Joint Returns filed by the Affiliated Group in such Tax jurisdiction shall determine the timing of the recognition
of Tax Items with respect to DITs and ELAs and the determination of which Legal Entity shall bear the Tax benefit or burden of such Tax Items, and the Company Group shall be responsible for the Tax Items recognized by its respective members with
respect to any DITs and ELAs, (3) the Separate Return Tax Liability with respect to a Joint Return filed in a state or locality shall be computed by taking into account such Tax Items, and such receipts or other data used to compute
apportionment factors, of each Company Group member as are taken into account with respect to such Company Group member in preparing such Joint Return, regardless of whether such Company Group member separately has tax nexus with such state or
locality, and (4) although the Separate Return Tax Liability is to be computed on a hypothetical basis as if the members of the Company Group that are part of the Affiliated Group were separate from the other members of the Affiliated Group,
the fact that such members of the Company Group are included in a Joint Return and the effect that such inclusion has on the calculation of any Tax Item or on any Tax reporting requirement, shall nevertheless be taken into account for purposes of
computing the Separate Return Tax Liability. Notwithstanding anything to the contrary in this Agreement, the Separate Return Tax Liability of the Company shall be determined by using, as the U.S. federal and applicable state or local Tax basis for
each Reference Asset (as defined in the Tax Receivable Agreement), an amount equal to the product of (i) twenty five percent (0.25 or 25%) and (ii) the actual Tax basis of such Reference Asset (as defined in the Tax Receivable Agreement)
at any relevant time, and, for the avoidance of doubt, taking into account only 25% of the actual depreciation or amortization of such Reference Asset for a Tax period. 

(pp) “Subsidiary” when used with respect to any Person, means (i)(A) a corporation a majority in voting power of whose share
capital or capital stock with voting power, under ordinary circumstances, to elect

encumbrance, (B) a partnership or limited liability company in which such Person or a Subsidiary of such Person is, at the date of determination, (1) in the case of a partnership, a general partner of such partnership with the power

and management of such limited liability company, or (C) any other Person (other than a corporation, partnership, or limited liability company) in which such Person and/or one or more Subsidiaries of such Person, directly or indirectly, at the
date of determination thereof, has or have (1) the power to elect or direct the election of a majority of the members of the governing body of such Person, whether or not such power is subject to a voting agreement or similar encumbrance, or
(2) in the absence of such a governing body, at least a majority voting interest or (ii) any other Person of which an aggregate of 50% or more of the equity interests are, at the time, directly or indirectly, owned by such Person and/or
one or more Subsidiaries of such Person. 
 (qq) “Tax” and “Taxes” means any and all federal, state, local
or non-U.S. taxes, charges, fees, duties, levies, imposts, rates or other like governmental assessments or charges, and, without limiting the generality of the foregoing, shall include income, gross receipts,
net worth, property, sales, use, license, excise, franchise, capital stock, employment, payroll, unemployment insurance, social security, Medicare, stamp, environmental, value added, alternative or added minimum, ad valorem, trade, recording,
withholding, occupation or transfer taxes, together with any related interest, penalties and additions imposed by any Tax Authority. The term “Taxable” shall have a correlative meaning; provided that, references to
“Taxable period” for any franchise or other doing business Tax (including, but not limited to, the Texas franchise Tax) shall mean the Taxable period during which the income, operations, assets, or capital comprising the base of such Tax
is measured, regardless of whether the right to do business for another Taxable period is obtained by the payment of such Tax. 
 (rr)
“Tax Asset” shall mean any Tax Item that has accrued for Tax purposes, but has not been realized during the Taxable period in which it has accrued, and that could reduce a Tax in another Taxable period, including a net operating
loss, net capital loss, disallowed business interest, general business tax credit, foreign tax credit, charitable deduction, credit related to alternative minimum tax, or any other Tax credit. 

(ss) “Tax Authority” means, with respect to any Tax, the governmental entity or political subdivision, agency, commission or
authority thereof that imposes such Tax, and the agency, commission or authority (if any) charged with the assessment, determination or collection of such Tax for such entity or subdivision. 

(tt) “Tax Benefit” means a reduction in the Tax liability (or increase in Tax Refund) of a Taxpayer for any Taxable period.
Except as otherwise provided in this Agreement, a Tax Benefit shall be deemed to have been realized or received from a Tax Item in a Taxable period only if and to the extent that the Tax liability (or Tax Refund) of the Taxpayer for such period,
after taking into account the effect of the Tax Item on the Tax liability (or Tax Refund) of such Taxpayer in the current period and all prior periods, is less than (or, in case of a Tax Refund, greater than) it would have been had such Tax

2. Separate Return Tax Liability of the Company Group; Accounting for Tax Benefits 

(a) Payment of Separate Return Tax Liability by the Company to Embraer U.S. 

(i) Estimated Tax Payments. Subject to Section 2(c), with respect to each Taxable period for which a Joint Return will be filed,
at least five (5) Business Days prior to each relevant Estimated Tax Installment Date, the Company shall pay to Embraer U.S. an amount equal to the installment of the estimated Separate Return Tax Liability, as shown in the computation provided
by Embraer U.S. to the Company pursuant to Section 2(b)(i). For the avoidance of doubt, the amounts paid by the Company to Embraer U.S. under this Section 2(a)(i) shall be taken into account in
determining the amounts to be paid by the Company or Embraer U.S., as the case may be, pursuant to Section 2(a)(ii). 

(ii) Final Return Tax Payments. Subject to Section 2(c), with respect to each Taxable period for which a Joint Return will be
filed (other than a Joint Return relating to estimated Tax payments), at least ten (10) Business Days prior to the due date (including extensions) for the filing of each such Joint Return, (1) the Company shall pay to Embraer U.S. an
amount equal to the excess, if any, of (x) the Separate Return Tax Liability of the Company Group for such Taxable period and such Joint Return over (y) the aggregate amount, if any, previously paid by the Company to Embraer U.S. with
respect to such Taxable period and such Joint Return under Section 2(a)(i), as shown in the computation provided by Embraer U.S. to the Company pursuant to Section 2(b)(i); and (2) Embraer
U.S. shall pay to the Company an amount equal to the excess, if any, of (x) the aggregate amount, if any, previously paid by the Company to Embraer U.S. with respect to such Taxable period and such Joint Return under
Section 2(a)(i) over (y) the Separate Return Tax Liability of the Company Group for such Taxable period and such Joint Return, as shown in the computation provided by Embraer U.S. to the Company pursuant to
Section 2(b)(i). 
 (b) Determination of Separate Return Tax Liability. 

(i) Manner of Calculation. For each Taxable period during which a Joint Return will be filed, Embraer U.S. shall provide to the
Company, not less than twenty (20) Business Days prior to the due date (including extensions) for the filing of such Joint Return (1) a pro forma draft of the portion of such Joint Return that reflects the Tax Items of the Company Group,
(2) a statement that sets forth in reasonable detail the computation of the Separate Return Tax Liability of the Company Group in respect of such Joint Return, and (3) the amount payable by the Company or Embraer U.S., as determined in
accordance with this Agreement, pursuant to Section 2(a); provided, however, that in the case of any Joint Return relating to estimated Tax 

  
 6 

 
payments, Embraer U.S. shall provide the foregoing information to the Company not less than ten (10) Business Days prior to each relevant Estimated Tax Installment Date. If the Company
disagrees with any Tax Item of the Company Group reflected on the pro forma draft of any Joint Return or any tax position relating to the computation of the Separate Return Tax Liability, then the Company shall promptly notify Embraer U.S. and the
parties shall use their reasonable best efforts to resolve the dispute. If the parties are unable to resolve any such dispute within ten (10) Business Days after the Company gives notice to Embraer U.S., then the matter shall be referred to a
nationally recognized accounting firm that is mutually acceptable to Embraer U.S. and the Company (the “Independent Accountant”) to resolve such dispute. All costs, fees, and expenses incurred with respect to the resolution
of such dispute shall be borne equally by Embraer U.S. and the Company, except that if the Independent Accountant determines that the proposed position submitted by a party to the Independent Accountant for its determination is frivolous, has not
been asserted in good faith, or is not supported by substantial authority, then 100% of such costs, fees, and expenses shall be borne by such party. If any dispute related to the computation of the Separate Return Tax Liability has not been resolved
by the due date for the payment of the Separate Return Tax Liability (including installments of estimated Separate Return Tax Liability) with respect to the applicable Joint Return as described in Section 2(a), then the
Company or Embraer U.S., as the case may be, shall make its payment based upon the original statement prepared by Embraer U.S., and any adjustments to such payment will be made in accordance with Section 5 following the
resolution of such dispute. 
 (ii) Separate Return Tax Liability. For purposes of this Agreement, the “Separate Return Tax
Liability” shall be determined as if the Company Group were filing a separate Tax Return under the Code or any analogous provisions of state or local Tax Law, and the term will not have the same meaning as set forth in Treasury Regulation Section 1.1502-12. For the avoidance of doubt, (A) the computation of the Separate Return Tax Liability of the Company Group shall be determined without regard to whether the Affiliated Group is obligated
to pay a Tax liability for the applicable Taxable period and (B) no Tax Asset or other Tax Item that has previously been taken into account in any Taxable period for the Company Group’s benefit in determining the Separate Return Tax
Liability payable under Section 2(a) or any amount payable under Section 5, or that has otherwise been realized by the Company Group, shall again be taken into account in this computation. If the
Separate Return Tax Liability of the Company Group for a Taxable period is less than zero, then the Separate Return Tax Liability of the Company Group shall be deemed to be zero for such period for purposes of Section 2(a).

 (c) Accounting for Tax Benefits. In the event that the Embraer U.S. Group recognizes a Tax Benefit on a Joint Return as a result
of the Separate Return Tax Liability being less than zero for a Taxable period, the amount of such Tax Benefit for such Taxable period shall be recorded and added to a cumulative register of prior Tax Benefits (the “Cumulative Tax Benefit
Register”). Amounts payable by the Company pursuant to Section 2(a)(i) or (ii) for any Taxable period may, at the option of the Company, reduce the amounts in the Cumulative Tax Benefit Register (but not below zero). Any reduction
in the amounts in the Cumulative Tax Benefit Register pursuant to the preceding sentence shall be treated, for purposes of this Agreement, as a payment in like amount by the Company to Embraer U.S. pursuant to Section 2(a). Within ten
(10) Business Days of filing a Joint Return, Embraer U.S. shall provide to the Company a statement setting forth in reasonable detail the computation of the amount, if any, reflected in the Cumulative Tax Benefit Register. For the avoidance of
doubt, no Tax Asset or other Tax Item that has been taken into account in any Taxable period for the Company Group’s benefit in determining the Separate Return Tax Liability payable under Section 2(a) or any amount
payable under Section 5, or that has otherwise been realized by the Company Group, shall again be taken into account for purposes of determining any amount added to the Cumulative Tax Benefit Register under this
Section 2(c). For the avoidance of doubt, no payment will be required to be made from Embraer U.S. to the Company on account of any amounts in the Cumulative Tax Benefit Register. 

3. Preparation and Filing of Tax Returns. 

(a) Joint Returns. Embraer U.S. shall be responsible for (i) preparing and filing (or causing to be prepared and filed) all Joint
Returns for any Taxable period and (ii) remitting (or causing to be remitted) to the proper Tax Authority the Tax shown on such Joint Returns. 

  
 7 

 (b) Separate Returns. 

(i) Embraer U.S. Separate Returns. Embraer U.S. shall be responsible for (1) preparing and filing (or causing to be prepared and
filed) all Separate Returns for any Taxable period that include one or more members of the Embraer U.S. Group and (2) remitting (or causing to be remitted) to the proper Tax Authority the Tax shown on such Separate Returns. 

(ii) Company Separate Returns. The Company shall be responsible for (1) preparing and filing (or causing to be prepared and
filed) all Separate Returns for any Taxable period that include one or more members of the Company Group and (2) remitting (or causing to be remitted) to the proper Tax Authority the Tax shown on such Separate Returns. 

(c) Provision of Information. The Company shall provide Embraer U.S. with all information necessary for Embraer U.S. or Parent to
properly and timely file all Joint Returns. Such information may include, but need not be limited to (i) a Tax Return package for Joint Returns and Separate Returns of the Company Group, (ii) an estimated Tax package for Joint Returns and
Separate Returns of the Company Group, (iii) a Tax provision package, (iv) a Tax projection package, and (v) workpapers and other supporting documentation relating to the foregoing (collectively, the “Tax Package”).
With respect to any Tax Items of the Company Group includible in a Joint Return, the Tax Package shall be prepared, with respect to such Tax Items, using the methods, conventions, practices, principles, positions, and elections used by Embraer U.S.
or Parent in preparing the applicable Joint Return. In the event the Company fails to provide information necessary for Embraer U.S. or Parent to properly and timely file a Joint Return in the form reasonably requested by Embraer U.S. and within
sufficient time to permit the timely filing of such Joint Return, the twenty (20) Business Day notice period (or ten (10) Business Day notice period in the case of estimated Tax payments) in Section 2(b)(i) shall
be waived, and any penalties, interest, or other payment obligation assessed against the Affiliated Group by reason of a delay in filing such Tax Return shall be payable by the Company, but only to the extent that such delay is attributable to the
Company’s failure to provide the necessary information on a timely basis. 
 (d) Special Rules Relating to the Preparation of Tax
Returns. 
 (i) Except as otherwise provided in this Agreement, the party that is responsible for filing (or causing to be filed) a Tax
Return pursuant to this Section 3 shall have the exclusive right, in its sole discretion, with respect to such Tax Return to determine (1) the manner in which such Tax Return shall be prepared and filed, including the
methods, conventions, practices, principles, positions, and elections to be used and the manner in which any Tax Item shall be reported, (2) whether any extensions may be requested, (3) whether an amended Tax Return shall be filed,
(4) whether any claims for refund shall be made, (5) whether any refunds shall be paid by way of refund or credited against any liability for the related Tax, and (6) whether to retain outside firms to prepare or review such Tax
Return; provided, however, that with respect to Joint Returns, Embraer U.S. shall prepare such Joint Returns in good faith and shall consult with the Company prior to changing any method of accounting if such action would impact the
Company Group. 
 (ii) With respect to any Separate Return for which the Company is responsible for filing (or causing to be filed), the
Company may not take (and shall cause the members of the Company Group not to take) any positions that it knows, or reasonably should know, are inconsistent with the methods, conventions, practices, principles, positions, or elections used by
Embraer U.S. in preparing any Joint Return, except to the extent that the failure to take such position would be contrary to applicable Tax Law. The Company and the other members of the Company Group shall (1) allocate Tax Items between such
Separate Return for which the Company is responsible and any related Joint Return for which Embraer U.S. is responsible that is filed in the same Tax year in a manner that is consistent with the reporting of such Tax Items on such related Joint
Return and (2) make any applicable elections required under applicable Tax Law necessary to effect such allocation. 
 4.
Tax Liability of the Company in the Event of Disaffiliation. Although neither party has any plan or intent to effectuate any transaction that would constitute a Deconsolidation Event, the parties have set forth how

  
 8 

 
certain Tax matters with respect to a Deconsolidation Event would be handled in the event that, as a result of changed circumstances, a transaction that constitutes a Deconsolidation Event occurs
at some future time. 
 (a) In General. In the case of a Deconsolidation Event, the Company and the Company Affiliates shall remain
liable under this Agreement for the Separate Return Tax Liability of the Company Group for the Taxable period during which such Deconsolidation Event occurs and for prior Taxable periods in which any such disaffiliated members of the Company Group
were members of the Affiliated Group, and the Company shall be required to pay Embraer U.S. all amounts for such Taxable periods that are determined pursuant to this Agreement. Moreover, should a Tax Proceeding ultimately result in assessment of a
Tax deficiency against any Affiliated Group for years in which the Company or the other members of the Company Group were affiliated with such Affiliated Group, the Company and the Company Affiliates shall remain liable for the Company Group’s
portion of such Tax deficiency determined pursuant to this Agreement, plus interest and penalties as provided in Section 6(a), if any. 

(b) Allocation of Tax Items. In the case of a Deconsolidation Event, all Tax computations for (i) any Pre-Deconsolidation Periods ending on the date of the Deconsolidation Event and (ii) the immediately following Taxable period of the Company or any disaffiliated members of the Company Group, shall be made
pursuant to the principles of Section 1.1502-76(b) of the Treasury Regulations or any similar provision of federal, state or local Tax Law, as reasonably determined by Embraer U.S. 

(c) Carrybacks. 
 (i)
Relinquishment. In the case of a Deconsolidation Event, notwithstanding any other provision of this Agreement, to the extent permitted by law, the Company hereby expressly agrees to elect (under Section 172(b)(3) of the Code and, to the
extent feasible, any similar provision of any federal, state or local Tax Law, including Section 1.1502-21(b)(3) of the Treasury Regulations) to relinquish any right to carryback net operating losses (or
other Tax Items, to the extent permissible) to any Pre-Deconsolidation Periods of Embraer U.S. (in which event no payment shall be due from Embraer U.S. to the Company in respect of such net operating losses
or other Tax Items). 
 (d) Continuing Covenants. Each of Embraer U.S. (for itself and each Embraer U.S. Affiliate) and the Company
(for itself and each Company Affiliate) agrees (i) not to take any action reasonably expected to result in an increased Tax liability to the other, a reduction in a Tax Asset of the other or an increased liability to the other under this
Agreement, and (ii) to take any action reasonably requested by the other that would reasonably be expected to result in a Tax Benefit; provided, in either such case, that the taking or refraining to take such action does not result in
any additional cost not fully compensated for by the other party or any other adverse effect to such party. The parties hereby acknowledge that the preceding sentence is not intended to limit, and therefore shall not apply to, the rights of the
parties with respect to matters otherwise covered by this Agreement. 
 (e) Cumulative Tax Benefit Register. Following any
Deconsolidation Event, Embraer U.S. will deliver to the Company a schedule setting forth the amounts remaining in the Cumulative Tax Benefit Register that have not applied to reduce payments hereunder within 120 days of such Deconsolidation Event.

 5. Adjustments. 

(a) Adjustment Payments. In the event of any Redetermination of any Joint Return, or resolution of any dispute between the parties by
the Independent Accountant or otherwise, which affects the calculation of the Company Group’s Separate Return Tax Liability or any other calculations or determinations under this Agreement for any Taxable period, the amounts required to be paid
pursuant to Section 2(a) or amounts added to the Cumulative Tax Benefit Register pursuant to Section 2(c), as applicable, (as well as any amounts required to be paid under
Section 6 below) shall be recomputed for such Taxable period to take into account such Redetermination or dispute resolution. The Company shall pay Embraer U.S., or Embraer U.S. shall pay the

  
 9 

 
Company, as applicable, an amount equal to the difference between the payment or payments previously made between the parties in respect of such redetermined Joint Return or Separate Return Tax
Liability and the amount that would have been paid pursuant to this Agreement in respect of such redetermined Joint Return (if such redetermined Joint Return had been filed on the basis of the Redetermination) or Separate Return Tax Liability. In
the event Embraer U.S. or Parent is required to pay to any Tax Authority any amount for additional Taxes due to the disallowance of all or part of any Tax Item for which the Company added an amount to the Cumulative Tax Benefit Register pursuant to
Section 2(c) and offset a payment under Section 2(a) (or if Embraer U.S. or Parent would have been so required to pay any Tax Authority but for other credits or adjustments), the Company shall pay
to Embraer U.S. the amount of such additional Tax paid by Embraer U.S. or Parent (or which Embraer U.S. or Parent would have been required to pay but for other credits or adjustments); provided, however, the amount so paid by the
Company to Embraer U.S. shall not exceed the cumulative amount credited to the Cumulative Tax Benefit Register by the Company pursuant to Section 2(c) with respect to such Tax Item (except as provided in
Section 6 below). If a payment is made as a result of a Redetermination or dispute resolution which does not conclude the matter, further adjusting payments will be made, as appropriate, to reflect the outcome of any
subsequent Redeterminations or dispute resolution, as applicable. 
 (b) Timing of Payments. Any payment by Embraer U.S. or the
Company required (x) by any dispute resolution shall be paid within five (5) Business Days after the date such dispute is resolved and (y) by any Redetermination in which (i) additional Taxes are paid, will be due five
(5) Business Days after the date on which the additional Taxes were paid or, if later, five (5) Business Days after the date of a request from the other party for the payment, or (ii) the amount or character of a Tax Item was adjusted
or redetermined, will be due five (5) Business Days after the date on which the final action resulting in such adjustment or redetermination is taken by a Tax Authority or either party or their Subsidiaries, as applicable. 

6. Payments. 

(a) Payment of Interest, Penalties, and Expenses. Interest, penalties, and expenses incurred by Embraer U.S. or Parent in connection
with the amendment of any Joint Return and/or any Tax Proceeding, shall be borne equitably by those parties whose Tax liability may be affected by such amendment or Tax Proceeding, unless otherwise provided under this Agreement. Embraer U.S. shall
act in good faith with respect to any interest, penalties, and expenses to be charged to the Company. 
 (b) Interest on Late
Payments. Payments pursuant to this Agreement that are not made by the date prescribed in this Agreement or, if no such date is prescribed, not later than five (5) Business Days after demand for payment is made (the “Due
Date”) shall bear interest for the period from and including the date immediately following the Due Date through and including the date of payment at the Interest Rate. Such interest will be payable at the same time as the payment to which
it relates. 
 (c) Tax Consequences of Payments. For all Tax purposes and to the extent permitted by applicable Tax Law, the parties
hereto shall treat any payment made pursuant to this Agreement as a capital contribution or a distribution, as the case may be, under the principles of Treasury Regulation Section 1.1552-1(b)(2), Treasury
Regulation Section 1.1502-33(d)(1)(ii), Revenue Ruling 73605, 1973-2 C.B. 109 or Revenue Ruling 76-302, 1976-2 C.B. 257, as applicable, and such payments will not create liabilities or receivables among the parties. If the receipt or accrual of any payment under this Agreement causes, directly or indirectly, an
increase in the taxable income of the recipient under one or more applicable Tax Laws, such payment shall be increased so that, after the payment of any Taxes with respect to the payment, the recipient thereof shall have realized the same net amount
it would have realized had the payment not resulted in taxable income. To the extent that any payment for which any party hereto (the indemnifying party) is required to pay another party (the indemnified party) pursuant to this Agreement may be
deducted or credited in determining the amount of any other Taxes required to be paid by the indemnified party (for example, state Taxes which are permitted to be deducted in determining federal Taxes), the amount of any payment made to the
indemnified party by the indemnifying party shall be decreased by taking into account any resulting reduction in other Taxes of the indemnified party. If such a 

  
 10 

 
reduction in Taxes of the indemnified party occurs following the payment made to the indemnified party with respect to the relevant indemnified Taxes, the indemnified party shall promptly repay
the indemnifying party the amount of such reduction when actually realized. If the Tax Benefit arising from the foregoing reduction of Taxes described in this Section 6(c) is subsequently decreased or eliminated, then the
indemnifying party shall promptly pay the indemnified party the amount of the decrease in such Tax Benefit. 
 7.
Indemnification. 
 (a) Indemnification by Embraer U.S. Embraer U.S. shall indemnify and hold harmless each member of
the Company Group from and against (i) any Taxes which a member of the Embraer U.S. Group is required to pay to a Tax Authority (except for Taxes, including the amount of any Separate Return Tax Liability, which Embraer U.S. has a right of
reimbursement hereunder from the Company), or in respect of which Embraer U.S. is required to make a payment hereunder to the Company, (ii) any Taxes imposed upon any member of the Company Group pursuant to Treasury Regulation Section 1.1502-6 or any analogous provision of state or local Tax Law for any Taxable period for which a Joint Return was filed in any Tax jurisdiction (except for Taxes, including the amount of any Separate
Return Tax Liability, which Embraer U.S. has a right of reimbursement hereunder from the Company) and (iii) any Taxes and Losses arising out of or based upon any breach or nonperformance of any covenant or agreement made or to be performed by
Embraer U.S. contained in this Agreement. For the avoidance of doubt, in no event shall Embraer U.S. be required to indemnify the Company with respect to the loss of any Tax attributes by any member of the Company Group. 

(b) Indemnification by the Company. The Company shall indemnify and hold harmless each member of the Embraer U.S. Group from and
against (i) any Taxes which a member of the Company Group is required to pay to a Tax Authority (except for Taxes which the Company has a right of reimbursement hereunder from Embraer U.S. or Taxes described in
Section 7(a)(ii)) or in respect of which the Company is required to make a payment hereunder to Embraer U.S. and (ii) any Taxes and Losses arising out of or based upon any breach or nonperformance of any covenant or
agreement made or to be performed by the Company contained in this Agreement. For the avoidance of doubt, in no event shall the Company be required to indemnify Embraer U.S. with respect to the loss of any Tax attributes by any member of the Embraer
U.S. Group. 
 8. Appointment of Agent. The Company consents to the appointment of Embraer U.S. (and Parent, if
Parent is not Embraer U.S.) as agent for the members of the Company Group in respect of all matters relating to Joint Returns, and agrees that Embraer U.S. (and Parent) shall have full authority to determine the Company Group’s Separate Return
Tax Liability in accordance with Section 2, to file Joint Returns (or otherwise cause any Joint Returns to be filed) and to make or change any Tax elections (or cause any Tax elections to be made or changed) on behalf of
the Company Group, and to control Tax Proceedings in accordance with Section 9, in each case, except as otherwise provided in this Agreement. The agency power of Embraer U.S. (and Parent), as described in this
Section 8, shall extend to all periods during which the Company or any member of the Company Group is a member of any Affiliated Group, and, in the event of the disaffiliation of the Company or any member of the Company
Group, Embraer U.S. (and Parent) shall retain its agency powers described herein to make or change on behalf of the Company, or any member of the Company Group, any election or other decision affecting Tax liabilities for such periods that the
Company or such member of the Company Group was affiliated with the Affiliated Group. 
 9. Tax Proceedings. 

(a) In General. Except as provided in Section 9(b), (i) with respect to any Joint Returns and any Separate
Returns described in Section 3(b)(i), Embraer U.S., and (ii) with respect to Separate Returns described in Section 3(b)(ii), the Company (in either case, the “Controlling Party”),
shall have the exclusive right, in its sole discretion, to control, contest, and represent the interests of each member of the Embraer U.S. Group and/or the Company Group, as applicable, in any Tax Proceeding relating to such Tax Return and to
resolve, settle or agree to any deficiency, claim or adjustment proposed, asserted or assessed in connection with or as a result of 

  
 11 

 
any such Tax Proceeding. Except as otherwise provided in Section 9(b), the Controlling Party’s rights shall extend to any matter pertaining to the management and
control of a Tax Proceeding, including execution of waivers, choice of forum, scheduling of conferences and the resolution of any Tax Item. 

(b) Participation of Non-Controlling Party. In any Tax Proceeding relating to a Joint Return in
which any Tax Item of the Company Group is a subject of such Tax Proceeding (a “Contested Company Group Item”), the Company shall be entitled to participate in such Tax Proceeding at its expense, insofar as the liabilities of the
Company Group are concerned, and Embraer U.S. shall consult with the Company with respect to any Contested Company Group Item, shall act in good faith with a view to the merits in connection with such Tax Proceeding, shall keep the Company updated
and informed with respect to such Contested Company Group Item and shall not settle or compromise any Contested Company Group Item in excess of $500,000 without the Company’s prior written consent, such consent not be unreasonably withheld or
delayed. 
 (c) Notice. If a party becomes aware of the existence of a Tax issue that may give rise to an indemnification obligation
under this Agreement, such party shall give prompt notice to the other party of such issue (and such notice shall contain factual information, to the extent known, describing any asserted Tax liability in reasonable detail), and shall promptly
forward to the other party copies of all notices and material communications with any Tax Authority relating to such issue. Failure to give timely notice shall not affect the indemnities given hereunder except, and only to the extent that, the
indemnifying party shall have been actually materially prejudiced as a result of such failure. 
 10. Cooperation.
The parties shall cooperate with one another in all matters relating to Taxes (and each shall cause its respective affiliates to so cooperate). The Company shall provide Embraer U.S., and Embraer U.S. shall provide the Company, with such
cooperation and information as is necessary in order to enable Embraer U.S., Parent and the Company to satisfy its Tax, accounting and other legitimate requirements. Unless otherwise provided under this Agreement, such cooperation and information
shall include (i) making the parties’ respective knowledgeable employees available during normal business hours, (ii) providing the information required by reasonable Tax and accounting questionnaires from the other party (at the
times and in the format as reasonably required by such other party), (iii) maintaining such books and records and providing such information as may be necessary or reasonably useful in the filing of Joint Returns and Separate Returns,
(iv) executing such documents as may be necessary or reasonably useful in connection with any Tax Proceeding, the filing of Joint Returns and Separate Returns, or the filing of refund claims by a member of the Embraer U.S. Group or the Company
Group (including certification, to the best of a party’s knowledge, of the accuracy and completeness of the information it has supplied), and (v) taking any actions which the other party may reasonably request in connection with the
foregoing matters. 
 11. Foreign Tax Returns. If the parties (or any members of their respective Groups) are
required to file (or the parties determine that it is in their best interests to file) a foreign Tax Return for any Taxable period ending on or after the Effective Date that includes at least two Legal Entities, of which one Legal Entity is a member
of the Company Group and the other Legal Entity is a member of the Embraer U.S. Group (or any such Legal Entity of one Group is required or able to file a Tax Return reflecting the Tax Assets of a Legal Entity of the other Group pursuant to a
similar or analogous scheme under applicable foreign Tax Law), the parties shall reasonably cooperate with one another to complete such Tax Returns, and to allocate the responsibility for payment of any Taxes or Tax Benefits with respect to such Tax
Returns, consistent with the underlying principles of calculation and allocation in this Agreement, with such changes as are necessary to reflect the Tax Laws of the applicable jurisdiction. 

12. Binding Effect; Assignment. Except as otherwise provided in Section 12(b) or 23,
this Agreement shall be binding upon and shall inure to the benefit of Embraer U.S., the Company, and each other party hereto and each other Legal Entity that becomes a party hereto pursuant to Section 12(b) or 23,
and this Agreement shall inure to the benefit of, and be binding upon, any successors or assigns of the parties hereto. Except as otherwise provided in Section 12(b) or 23, each of Embraer U.S. and the Company may
assign its right to receive payments under this Agreement but may not assign or delegate any other right or obligation hereunder. 

  
 12 

 13. No Third Party Beneficiaries. Except as provided in
Sections 7, 12 and 23, this Agreement is solely for the benefit of Embraer U.S. and the Company and is not intended to confer upon any other Person any rights or remedies hereunder. 

14. Application of Agreement. This Agreement shall be applicable only to Taxable periods of the Company and the
members of the Company Group ending on or after the Effective Date and to each Taxable period thereafter. 
 15.
Interpretation. This Agreement is intended to calculate, allocate and settle certain Tax liabilities of the members of the Embraer U.S. Group and the Company Group, and any situation or circumstance concerning such calculation
and allocation that is not specifically contemplated hereby or provided for herein shall be dealt with in a manner consistent with the underlying principles of calculation and allocation in this Agreement. 

16. Legal and Accounting Fees. Unless otherwise specified herein, any fees or expenses (including internal
expenses) for legal, accounting or other professional services rendered in connection with Tax research relating to the Company Group, the preparation of a Joint Return or any statement relating to any Separate Return Tax Liability or other
calculations under this Agreement or the conduct of any Tax Proceeding shall be allocated between Embraer U.S. and the Company in a manner resulting in Embraer U.S. and the Company, respectively, bearing a reasonable approximation of the actual
amount of such fees or expenses hereunder reasonably related to, and for the benefit of, their respective Groups. The Company shall pay Embraer U.S. for any fees and expenses allocated to the Company pursuant to this
Section 16 within five (5) Business Days after the date the Company receives notice from Embraer U.S. requesting such payment. 

17. Effect of the Agreement. This Agreement shall determine the liability of Embraer U.S. and the Company to each
other as to the matters provided for herein, whether or not such determination is effective for purposes of the Code or state or local Tax Laws, or for financial reporting purposes or for any other purposes. 

18. Allocation Among the Company and Its Included Subsidiaries. Nothing herein shall be deemed to preclude or
require any allocation of the Separate Return Tax Liability of the Company Group among or between the Company and its Subsidiaries. 

19. Modifications. This Agreement shall not be modified or terminated except by a writing duly signed by each of
the parties hereto, and no waiver of any provisions of this Agreement shall be effective unless in a writing duly signed by the party sought to be bound, except that any addition of a new party pursuant to Section 12(b) or
23 shall not require a writing signed by any other party. 
 20. Entire Agreement. This Agreement
embodies the entire agreement among the parties hereto with respect to the matters covered hereby and thereby, and all prior written or oral agreements, representations, warranties or covenants previously existing between the parties with respect to
such subject matter are cancelled and are not part of this Agreement. 
 21. Changes in Law. 

(a) Any references to the Code or Treasury Regulations, or a law of another jurisdiction, shall be deemed to refer to the relevant provisions
of any successor statute or regulation and shall refer to such provisions as in effect from time to time. 
 (b) If, due to any change in
applicable law or regulations or their interpretation by any court of law or other governing body having jurisdiction subsequent to the Effective Date, performance of any provision of this Agreement or any transaction contemplated thereby shall
become impracticable or impossible, the parties hereto shall use their commercially reasonable efforts to find and employ an alternative means to achieve the same or substantially the same result as that contemplated by such provision.

hereby, as if such Person were a signatory hereto (whether or not such Person signs a counterpart of this Agreement or enters into a joinder agreement or similar instrument with respect hereto). 

(ii) Notwithstanding the provisions of clause (i) of this Section 23(b), and without limiting the rights of
any Embraer U.S. Successor or Embraer U.S. Successor Parent, the Company agrees that following the effective time of a transaction described in clause (i) of this Section 23(b) (an “Embraer U.S. Successor
Transaction”) in which Embraer U.S. continues as a legal entity, and with respect to Joint Returns for Taxable periods beginning prior to the effective time of such Embraer U.S. Successor Transaction, (a) Embraer U.S. shall continue to

 EACH PARTY HERETO ACKNOWLEDGES AND AGREES THAT ANY CONTROVERSY WHICH MAY ARISE UNDER THIS AGREEMENT IS LIKELY TO

 Exhibit 10.16 

EMPLOYMENT AGREEMENT 

This Employment Agreement (this “Agreement”) is made and entered into as of September 14, 2021 (the “Effective
Date”), by and among Embraer Aircraft Holding, Inc. (the “Company”), together with its respective subsidiaries, and, on and after the Closing Date (as defined below), Newco (as defined below), the “Company
Group”) Embraer S.A. (“Embraer”) solely with respect to Section 11 hereof, and Gerard J. DeMuro (“Executive” and, together with the Company and Parent, the
“Parties”). 
 RECITALS 

WHEREAS, Embraer and Zanite Acquisition Corp. (“Zanite”) are in discussions with respect to a possible business combination
(the “Business Combination”) whereby, among other things, EVE Urban Air Mobility Solutions, Inc. (“EVE”) would become a direct or indirect wholly-owned subsidiary of Zanite,
Zanite would continue to be a public company with securities listed for trading in the public market, Parent would become a direct or indirect owner of a majority of Zanite’s outstanding equity securities and Zanite would change its name to EVE
Urban Air Mobility Solutions Inc. (such post-Business Combination entity referred to herein as “Newco”); 

WHEREAS, such business combination will be accomplished pursuant to a business combination agreement by and among Embraer, Zanite, EVE and
other parties thereto (the “BCA”); 
 WHEREAS, in furtherance of the possible Business Combination, the Parties intend that
Executive shall commence employment as the Co-Chief Executive Officer of EVE effective as of the date on which Zanite appoints a replacement member for its board of directors (the “Employment
Commencement Date”) and to also serve as Co-CEO of Newco and a member of the Board of Directors of Newco (the “Newco Board”) upon completion of the Business Combination. 

NOW, THEREFORE, in consideration of the mutual covenants and agreements hereinafter set forth and for other good and valuable consideration,
the receipt of which are hereby acknowledged, the Parties hereto agree as follows: 
 1. Term. Executive’s employment with the
Company under the terms and conditions of this Agreement shall commence on the Employment Commencement Date and shall continue during an initial term until the second anniversary of the Employment Commencement Date (the “Initial
Term”), provided that upon completion of the Business Combination, the Initial Term shall automatically be extended to the second anniversary of the effective date of the Business Combination (the “Closing Date”), and
automatically renew for successive one-year terms thereafter (the “Subsequent Term” and together with the Initial Term, the “Term”), in each case, until terminated in
accordance with the terms and conditions of Section 5 of this Agreement. Notwithstanding any provision of this Agreement to the contrary, Executive shall be employed on an
“at-will” basis and Executive’s employment may be terminated by either Party at any time, subject to the notice provisions contained herein that may apply with respect to termination of
employment. 

 2. Title; Services and Duties. 

(a) During the Term, Executive shall be employed by the Company as EVE’s Co-Chief Executive Officer, and shall report to the Board of
Directors of EVE (the “Board”), pursuant to the terms of this Agreement. Effective as of the Closing Date, Executive shall also serve as Co-CEO of Newco reporting to the Board of Directors of
Newco. 
 (b) During the Term, Executive shall (i) be a full-time employee of the Company, or such other member of the Company Group as
determined by the Board, (ii) have such duties, responsibilities and authority as set forth on Exhibit B hereto and as may reasonably be prescribed by the Board, consistent with Executive’s position as
Co-Chief Executive Officer and (iii) devote all of Executive’s business time and best efforts to the performance of his duties to the Company Group and shall not engage in any other business,
profession or occupation for compensation. Notwithstanding the foregoing, Executive may (x) serve as a director or advisor of non-profit organizations without approval of the Board and as director or
advisor of for profit companies with the prior approval of the Board, which shall not be unreasonably withheld, (y) perform and participate in civic, charitable, educational, professional, community, industry affairs and other related
activities, and (z) manage personal investments; provided, however, that such activities do not materially interfere, individually or in the aggregate, with the performance of his duties hereunder and do not materially breach
Section 6(c) hereof. For the avoidance of doubt, effective on or prior to the Employment Commencement Date, Executive shall resign his position as a member of the Zanite Board of Directors. 

(c) The principal location of Executive’s employment with the Company shall be in Washington D.C., although Executive understands and
agrees that any office location required by Executive in Washington D.C. shall be at Executive’s sole expense and that Executive may be required to travel from time to time for business reasons including regular travel to the Company’s
headquarters in Melbourne, Florida. 
 3. Compensation. 

(a) Base Salary. The Company Group shall pay Executive a base salary in an amount no less than $400,000 per annum (as in effect from
time to time, the “Base Salary”) during the Term, payable in accordance the Company Group’s regular payroll practices as in effect from time to time. Executive will be eligible for Base Salary increases on the same terms and
conditions as apply to the Company’s similarly situated executives. 
 (b) Long Term Incentive Award. On the Closing Date,
Executive shall be granted a one-time equity or equity based award of up to 260,000 shares of common stock Newco, pursuant to a long-term incentive plan to be adopted by Newco pursuant to the BCA (the
“Initial Grant”). Except as otherwise provided in Section 3(b)(i) below, the Initial Grant shall vest on the second anniversary of the Closing Date, subject, except as otherwise provided in
Section 5 below, to Executive’s continued employment with the Company Group through such vesting date. The number of shares actually awarded to Executive in connection with the Initial Grant shall be calculated in the
following manner: 

 (i) 100,000 fully-vested shares (the “Fully-Vested Shares”) shall be
awarded to Executive on the Closing Date; provided, however, during the 24-month period following the Closing Date, Executive will retain all, and will not sell or transfer any, of such shares, that such
shares may also be subject to the terms and conditions set forth in a lock-up agreement to be entered into between Newco and its directors and officers generally and, to the extent the lock-up agreement does not permit the sale of shares to cover taxes, Executive shall be permitted to remit a number of shares to Newco to satisfy any tax withholding obligations; 

(ii) In the event the PIPE Raise exceeds $250,000,000, zero to 120,000 shares (the “PIPE Shares”) shall be awarded to
Executive on the Closing Date (the amount of shares actually issued shall be based on a linear sliding scale between $250,000,000 and $400,000,000, such that 4,000 shares will be issued for each $5,000,000 and fraction thereof by which the PIPE
Raise exceeds $250,000,000); 
 (iii) Up to 20,000 shares (the “Operating Model Shares”) shall be issued to Executive on
the Closing Date based on the Executive’s collaboration with the EVE team on the Company’s operating model, as determined by the Compensation Committee or the Board (to the extent a compensation committee has not been formed); and 

(iv) Up to 20,000 shares (the “Personnel Shares”) shall be issued to Executive on the Closing Date based on the
Executive’s recruitment of the Board and select key management positions, as determined by the Compensation Committee or the Board (to the extent a compensation committee has not been formed). 

For purposes of this Agreement, “PIPE Raise” shall mean the amount of cash invested in the Company, Zanite or Newco after the
Employment Commencement Date and on or prior to the Closing Date, excluding any cash contributions from Embraer (or its affiliates) or from Zanite (or its affiliates), but including cash investments from any strategic investors, PIPE investors and
other investors. 
 (c) Performance-Based Equity Award. On the Closing Date, the Executive shall also be granted a one-time equity or equity based award of 200,000 shares of Newco common stock (the “Performance-Based Grant”). Shares earned under the Performance-Based Grant shall vest on the second anniversary of
the Closing Date subject, except as provided in Section 5 below, to Executive’s continued employment with the Company through such vesting date. The number of shares earned in connection with the Performance-Based
Grant shall be based on the achievement of certain performance criteria and calculated in the following manner:  
 (i) Up to 100,000
shares (the “First Year Shares”) shall be earned on the first anniversary of the Closing Date based upon performance against organizational targets as mutually agreed by Executive and the Compensation Committee or the Board (to the
extent a Compensation Committee has not been formed), and any of the 100,000 shares not earned as of the first anniversary shall be forfeited; and 

 (ii) Up to 100,000 shares (the “Second Year Shares”) shall be earned on
the second anniversary of the Closing Date based upon performance against organizational targets as mutually agreed by Executive and the Compensation Committee or to the Board (to the extent a Compensation Committee has not been formed), and any of
such 100,000 shares that are not earned as of the second anniversary shall be forfeited. 
 4. Employee Benefits. 

(a) Employee Benefits and Perquisites. During the Term, Executive shall be eligible to participate in all benefit plans made available
by the Company Group to its senior executives generally. Such benefits shall be subject to the applicable limitations and requirements imposed by the terms of such benefit plans and shall be governed in all respects in accordance with the terms of
such plans as in effect from time to time. Nothing in this Section 4(a), however, shall require the Company or any member of the Company Group to maintain any benefit plan or provide any type or level of benefits to its
current employees, including Executive. 
 (b) Paid Vacation. During the Term, Executive shall be entitled to not less than four
weeks of paid vacation per calendar year (pro-rated for the calendar year in which the Employment Commencement Date occurs) in accordance with the terms and conditions of the Company’s vacation policies
as in effect from time to time. 
 (c) Reimbursement of Business Expenses. The Company Group shall reimburse Executive for any
expenses reasonably and necessarily incurred by Executive during the Term in furtherance of Executive’s duties hereunder, including travel, meals and accommodations, upon submission by Executive of vouchers or receipts and in compliance with
such rules and policies relating thereto as the Company may from time to time adopt. The Company Group shall pay or reimburse Executive for Executive’s costs and expenses in connection with the review, negotiation and execution of this
Agreement and any agreements related hereto up to a maximum of $50,000. 
 (d) Indemnification and Insurance. The Company Group will
indemnify Executive (including advancement of expenses in connection therewith) and hold Executive harmless in accordance with, and subject to, the terms of each Company Group member’s organizational documents. The Company Group will also cover
Executive under the Company Group’s directors’ and officers’ liability insurance policies, on the same terms and conditions it covers any of its similarly situated officers and/or directors. Executive’s rights under this
Section 4(d) shall not be exclusive and shall be in addition to any other rights and insurance coverage to which the Executive may be entitled under (i) applicable law or (ii) any other agreement, including the BCA. 

5. Termination of Employment. Executive’s employment shall be terminated at the earliest to occur of the following: (i) the
date on which the Company Group provides notice to Executive of termination for “Disability” (as defined below); (ii) the date of Executive’s death; (iii) the date on which Executive’s employment is terminated for
“Cause” (as defined below); (iv) the date which is 30 days following the date on which the Company Group provides notice to Executive of termination without Cause; (v) the date which is 30 days following the date on which Executive
provides notice to the Company of his voluntary resignation other than for Good Reason (as defined below); or (vi) the date on which Executive’s employment terminates due to his resignation for Good Reason. 

 (a) For Cause; Resignation by Executive Other than for Good Reason; Death or
Disability. If during the Term Executive’s employment with the Company Group is terminated by the Company for Cause or as a result of Executive’s death or Disability, or Executive resigns his employment other than for Good Reason,
Executive shall not be entitled to any further compensation or benefits other than, in each case if applicable as of the date of termination: (i) any accrued but unpaid Base Salary (payable as provided in Section 3(a)
hereof); (ii) reimbursement for any expenses properly incurred prior to the date of termination and reported by Executive in accordance with Section 4(c) hereof, payable on the Company Group’s first regularly scheduled
payroll date which occurs at least 10 business days after the date of termination; and (iii) vested employee benefits, if any, to which Executive may be entitled under the Company Group’s employee benefit plans described in
Section 4(a) and Section 4(b) as of the date of termination, payable as provided in such employee benefit plans (collectively, the “Accrued Rights”). Notwithstanding the foregoing,
if employment termination is due to death or Disability and Executive (or his estate, as applicable) executes a release of claims in the form attached as Exhibit A hereto, subject to any revisions necessary to reflect changes in applicable
law occurring after the date hereof (the “Release”), Executive (or his estate, as applicable) shall be entitled to receive, (x) if such termination occurs after the equity awards have been granted and prior to vesting of the
equity awards in accordance with Sections 3(b) and (c), accelerated vesting to the Severance Payment Date (or if earlier, the vesting date of the awards described in Sections 3(b) and 3(c)) of (A) all shares granted under the
Initial Grant, and (B) all shares granted under the Performance-Based Grant, provided, however, that if such termination occurs after the first anniversary of the Closing Date, the number of Performance-Based Shares that vest shall be equal to,
provided that such Initial Grant shall be fully vested, the number of First-Year Shares that were earned as of such first anniversary plus the number of Second-Year Shares (such total number of shares determined under clause (A) and (B) the
“Acceleration Shares”) and (y) in the event that such termination occurs prior to the date on which such equity awards are granted and the Closing Date subsequently occurs, the Initial Grant will be made to Executive not later
than the time it would otherwise be made under Section 3(b) above had Executive’s employment with the Company continued through such date. 

(b) Termination by the Company without Cause or Resignation for Good Reason. If during the Term Executive’s employment is
terminated by the Company Group without Cause or Executive resigns his employment for Good Reason, then Executive shall be entitled to receive the Accrued Rights, and if (i) Executive executes a Release and the applicable revocation period with
respect to the Release expires within 30 days (or such longer period as required by law) following the date of termination and (ii) Executive does not materially breach the restrictive covenants set forth in Section 6
hereof, then Executive shall receive the following: 
 (i) An amount in cash equal to one times Executive’s Base Salary, as in effect
immediately prior to the date of termination (without regard to any reduction resulting in Good Reason) which amount shall be paid to Executive on the first regularly scheduled payroll date of the Company Group that occurs on or following the 60th day after the date of termination (the “Severance Payment Date”); 

 (ii) Provided that Executive timely elects to continue coverage under the Consolidated
Omnibus Budget Reconciliation Act of 1985 (“COBRA”), for the 12 calendar months immediately following the end of the calendar month in which the date of termination occurs, the Company shall pay a portion of
the premiums so that Executive’s cost for coverage is commensurate with active employees; provided, that, if the Company determines that such payments would cause adverse tax consequences to the Company or
Executive or otherwise not be permitted under the Company Group’s health and welfare plans or under law, the Company shall instead provide Executive with monthly cash payments during such 12 month period in an
amount equal to the amount of the Company’s monthly contributions referenced above; provided, further, that such contributions shall cease to be effective as of the date that Executive obtains health and welfare benefits
from a subsequent employer; and 
 (iii) if such termination occurs (A) prior to the date on which such equity awards are granted and
the Closing Date subsequently occurs, the Initial Grant will be made to Executive not later than the time it would otherwise be made under Section 3(b) above had Executive’s employment with the Company continued
through such date provided that such Initial Grant shall be fully vested, or (B) if such termination occurs after the equity awards have been granted and prior to vesting of the equity awards in accordance with
Section 3(b) and 3(c), accelerated vesting of the Acceleration Shares (determined and vesting as described in Section 5(a)). 

(c) Definitions. For purposes of this Agreement: 

(i) “Affiliate” as applied to any Person, means any other Person directly or indirectly controlling, controlled by, or under
common control with, that Person. For the purposes of this definition “control” (including, with correlative meanings, the terms “controlling”, “controlled by” and “under common control
with”), as applied to any Person, means the possession, directly or indirectly, of the power to direct or cause the direction of the management and policies of that Person, whether through the ownership of voting securities (the ownership
of more than 50% of the voting securities of an entity shall for purposes of this definition be deemed to be “control”), by contract or otherwise provided that following the Closing Date no direct or indirect shareholder of Newco
(including Embraer and the Company) shall be considered to be an Affiliate of Newco or its Subsidiaries. 
 (ii) “Cause”
means (in each case, other than due to death or Disability): Executive’s (A) conviction of, or pleading nolo contendere to, a felony, (B) conviction of, or pleading nolo contendere to, any crime, whether a felony or misdemeanor,
involving the purchase or sale of any security, mail or wire fraud, theft, embezzlement or moral turpitude (it being understood that de minimis personal use or taking of office equipment, supplies and similar resources shall not constitute
theft or embezzlement); (C) commission of any act involving dishonesty fraud, misrepresentation, or breach of trust, in each case that causes or is reasonably expected to result in a material injury to the Company Group; or (D) willful
misconduct or gross negligence in connection with, or failure or refusal to perform, following lawful instruction by the Board or Newco Board, Executive’s duties and obligations as an employee, including confidentiality and code of conduct
obligations. “Cause” and the applicability of the foregoing definition shall be determined in good faith in the sole discretion of the Board. Notwithstanding the foregoing, in no event will the occurrence of any such condition constitute
Cause unless (1) the Company provides notice to Executive of the existence of the condition giving rise to Cause within 30 days following the Company’s knowledge of its existence and (2) if curable, Executive fails to cure such
condition within 30 days following the date of such notice, upon which failure to cure Executive’s employment will immediately terminate for Cause. 

 (iii) “Disability” means Executive becoming physically or mentally
incapacitated and therefore unable for a period of 45 consecutive working days or 75 working days in any six (6) month period to perform the duties hereunder, with or without reasonable accommodations, as determined by the Board in its sole
discretion. If possible, the Company will engage in an interactive process with Executive to determine whether Executive can perform the duties hereunder with reasonable accommodations. 

(iv) “Good Reason” means, in each case without Executive’s prior written consent, (A) a diminution in
Executive’s Base Salary from the amounts described in Section 3(a); (B) a material diminution in Executive’s duties, responsibilities authority or an adverse change in Executive’s title or role;
(C) a requirement that Executive report to anyone other than as provided in Section 2(a); (D) a material breach by the Company or any member of the Company Group of this Agreement or any other agreement between the
Company or any member of the Company Group with Executive (including, for the avoidance of doubt, any failure to grant the equity awards consistent with the terms set forth in this Agreement); or (E) the BCA has not been executed within 180
days of the Employment Commencement Date. Notwithstanding the foregoing, in no event will the occurrence of any such condition constitute Good Reason unless (1) Executive provides notice to the Company of the existence of the condition giving
rise to Good Reason within 60 days following Executive’s knowledge of its existence and (2) the Company fails to cure such condition within 30 days following the date of such notice, upon which failure to cure Executive’s employment
will immediately terminate with Good Reason. 
 (v) “Person” means any individual, corporation, partnership, limited
liability company, joint venture, association, trust or other entity or organization, including a government or political subdivision or an agency or instrumentality thereof. 

6. Restrictive Covenants. 
 (a)
Acknowledgment. Executive agrees and acknowledges that, in the course of Executive’s employment, Executive shall acquire access to and become acquainted with information about the Company Group that is
non-public, confidential or proprietary in nature. Executive acknowledges that the EVE is engaged throughout the world in a highly competitive business and the success of the EVE in the marketplace depends
upon its goodwill and reputation, and that Executive has developed and shall continue to develop such goodwill and reputation through substantial investment by the EVE. Executive agrees and acknowledges that reasonable limits on Executive’s
ability to engage in activities competitive with the EVE are warranted to protect its substantial investment in developing and maintaining its status in the marketplace, reputation and goodwill. Executive recognizes that in order to guard the
legitimate interests of the EVE, it is necessary for it to protect all “Confidential Information” (as defined below) and the disclosure of Confidential Information would place the EVE at a competitive disadvantage. Executive further
agrees that Executive’s obligations under this Section 6 are reasonable and shall be absolute and unconditional. 

 (b) Confidential Information. During Executive’s employment and at all times
following Executive’s termination of employment for any reason, Executive shall hold in a fiduciary capacity for the benefit of the Company Group all non-public information, matters and materials of the
Company Group, including, without limitation, know-how, trade secrets, customer lists, pricing policies, operational methods, information relating to products, processes, customers, services and other business
and financial affairs, and information as to customers or other third parties (collectively, the “Confidential Information”), in each case to which Executive has had or may have access and shall not, subject to Section 6(h),
below, directly or indirectly, use or disclose such Confidential Information to any Person other than (i) to the extent required or deemed advisable by Executive in good faith in the course of Executive’s employment or as otherwise
expressly required in connection with court process or requested by a governmental or regulatory body, (ii) as may be permitted pursuant to Section 6(h) or (iii) to Executive’s personal advisers for purposes of enforcing or
interpreting this Agreement (or in the case of any other litigation between Executive and the Company Group), or to a court or arbitrator for the purpose of enforcing or interpreting this Agreement (or in the case of any other litigation between
Executive and the Company Group), and who in each case have been informed as to the confidential nature of such Confidential Information and, as to advisers, their obligation to keep such Confidential Information confidential. Notwithstanding the
foregoing, “Confidential Information” shall not include any information which is in the public or industry domain during Executive’s employment or becomes publicly known or made generally available at any time through no wrongful act
of Executive. For the avoidance of doubt, information regarding EVE’s clients obtained by Executive prior to the Employment Commencement Date, and his knowledge of methods, processes, techniques and best practices in general use in the private
markets industry (collectively, “Existing and General Information”) shall not constitute “Confidential Information” or trade secrets of EVE for any purpose under this Agreement or applicable law. Upon the termination of
Executive’s employment for any reason or upon the request of the Company at any time, Executive shall deliver to the Company all documents, papers and records (including, but not limited to, electronic media) in Executive’s possession or
subject to Executive’s control that (x) belong to the Company Group or (y) contain or reflect any Confidential Information concerning the Company Group; provided, that Executive may retain personal and business contact information and
records relating to Executive’s compensation. To the extent such documents, papers and records are stored or maintained on any personal computer, email, cloud account, or other storage device and cannot be returned to the Company in their
entirety, Executive agrees to permanently delete such materials upon the instruction of the Company. 
 (c) Non-Competition and Non-Solicitation. During Executive’s employment and for a period of 12 months after Executive’s employment ends for any reason, Executive
will not, whether for Executive’s own account or for any other Person, directly or indirectly, with or without compensation: 
 (i)
Own, operate, manage, or control, serve as an officer, director, partner, employee, agent, consultant, advisor or developer or in any similar capacity to, or have any financial interest in, or aid or assist anyone else in the conduct of any
Competitive Business. For purposes of this Agreement, “Competitive Business” means any Person which engages, or is preparing to engage, in the research, design, development, testing, engineering, licensing, certification,
manufacturing, procurement, assembling, packaging, sales support and after-sales support of, marketing, promotion, advertising, qualification, distribution, importation, fulfillment, offering, sale, deployment, delivery, provision, exploitation,
configuration, installation, integration, analysis, support, maintenance, repair, service and other commercialization of or provision of services with respect to eVTOL and related products and services and the UATM for the UAM market; or
(ii) any product line of or service offered by the Company or any member of the Company Group with respect to which Executive had direct or indirect involvement, or about which Executive received or had access to Confidential Information, in
each case, anywhere in the world; 

 (ii) Solicit, divert, take away or attempt to solicit, divert or take away any of the
customers, prospective customers or suppliers or any other business contacts of the Company or any member of the Company Group with whom Executive first had direct or indirect contact, or about whom Executive received or had access to Confidential
Information, during Executive’s employment with the Company Group; or 
 (iii) Solicit, retain, knowingly hire, knowingly offer to
hire, entice away or in any manner persuade or attempt to persuade any officer, employee or agent of the Company or any member of the Company Group who was employed, engaged or recruited within the last 12 months of Executive’s employment with
the Company Group to discontinue his relationship with the Company Group. 
 Non-targeted, general, solicitations to
the public shall be deemed not to breach this Section 6. Notwithstanding the foregoing, nothing in Section 6(c) will prohibit Executive from (i) acquiring or passive ownership of not more than two percent (2%) of any class of
securities of any company or (ii) being employed by, otherwise providing services to, or owning any interest in a Person that would otherwise be considered a Competitive Business, provided that Executive’s employment with or other service
to such Person is not related (other than in immaterial respects) to the business of such Person that is a Competitive Business (it being understood that Executive shall be required to provide the Company Group with reasonable details of such
position, including with respect to duties and responsibilities). 
 (d) Intellectual Property. All copyrights, trademarks, trade
names, servicemarks, patents, trade secrets, ideas (whether or not protectible under trade secret laws), inventions, concepts, processes, methods, techniques and other intangible or intellectual property rights that are invented, conceived,
developed, created, enhanced or reduced to practice by Executive (whether solely or jointly with others) during Executive’s employment with the Company Group (whether prior to or after the Effective Date) (“Company Inventions”)
shall be the sole property of EVE. Executive hereby irrevocably assigns to EVE all of Executive’s right, title and interest in and to the Company Inventions and waives any right or interest that Executive may otherwise have in respect of any
Company Inventions. Executive shall promptly disclose and describe to the Company Group all Company Inventions. Upon request of the Company Group, Executive shall execute, acknowledge and deliver any assignment or other instrument or document
reasonably necessary or appropriate to give effect to this Section 6(d) and do all other acts and things reasonably necessary, at the Company Group’s expense, to enable the Company or its applicable Affiliate, as the
case may be, to exploit the same or to obtain or perfect their rights with respect thereto. 
 (e) Compliance with Obligations.
Executive represents and covenants that (i) Executive has made the Company Group aware of any contract or other arrangement with any present or past employer that restricts Executive’s ability to be employed by and/or solicit clients,
investors, employees or other third parties on behalf of the Company Group; (ii) Executive has not disclosed to the Company Group any information with respect to which Executive owes any 

 
obligation of confidentiality or non-use to any present or past employer or other third party; (iii) Executive has fully complied with
Executive’s contractual and common law obligations to all present and past employers and persons to whom Employee has provided services; and (iv) Executive’s execution of this Agreement and employment by the Company Group does not
require Executive to violate, and Executive has not violated and will not violate, any such obligation. Executive represents and covenants that Employee will be bound by and comply with the policies, procedures and practices of the Company Group in
effect from time to time during Executive’s employment with the Company Group. 
 (f) Modification. The parties agree and
acknowledge that the duration, scope and geographic area of the covenants described in this Section 6 are fair, reasonable and necessary in order to protect the goodwill and other legitimate interests of the Company Group,
that adequate consideration has been received by Executive for such obligations, and that these obligations do not prevent Executive from earning a livelihood. If, however, for any reason any arbitrator or court of competent jurisdiction determines
that the restrictions in this Section 6 are not reasonable, that consideration is inadequate or that Executive has been prevented unlawfully from earning a livelihood, such restrictions shall be interpreted, modified or
rewritten to include as much of the duration, scope and geographic area identified in this Section 6 as shall render such restrictions valid and enforceable. 

(g) Remedies for Breach. The Parties agree that the restrictive covenants contained in this Agreement are severable and separate, and
the unenforceability of any specific covenant herein shall not affect the validity of any other covenant set forth herein. Executive acknowledges that the Company Group shall suffer irreparable harm as a result of a material breach of such
restrictive covenants by Executive for which an adequate monetary remedy does not exist and a remedy at law may prove to be inadequate. Accordingly, in the event of any actual or threatened material breach by Executive of any provision of this
Section 6, the Company shall, in addition to any other remedies permitted by law, be entitled to seek to obtain remedies in equity, including, without limitation, specific performance, injunctive relief, a temporary
restraining order, and/or a permanent injunction in any court of competent jurisdiction in aid of arbitration (each, an “Equitable Remedy”), to prevent or otherwise restrain a material breach of this
Section 6, without the necessity of proving damages, posting a bond or other security. Such relief shall be in addition to and not in substitution of any other remedies available to the Company. The existence of any claim
or cause of action of Executive against the Company, whether predicated on this Agreement or otherwise, shall not constitute a defense to the enforcement by the Company of said covenants. 

(h) Permitted Disclosures. Pursuant to 18 U.S.C. §1833(b), Executive shall not be held criminally or civilly liable under any
Federal or State trade secret law for the disclosure of a trade secret of the Company Group that (i) is made (A) in confidence to a Federal, State, or local government official, either directly or indirectly, or to Executive’s
attorney, and (B) solely for the purpose of reporting or investigating a suspected violation of law; or (ii) is made in a complaint or other document that is filed under seal in a lawsuit or other proceeding. If Executive files a
lawsuit for retaliation by the Company Group for reporting a suspected violation of law, Executive may disclose the trade secret to Executive’s attorney and use the trade secret information in the court proceeding, if Executive (1) files
any document containing the trade secret under seal, and (2) does not disclose the trade secret, except pursuant to court order. Nothing in this Agreement is intended 

 
to conflict with 18 U.S.C. §1833(b) or create liability for disclosures of trade secrets that are expressly allowed by such section. Further, nothing in any agreement Executive has with the
Company Group shall prohibit or restrict Executive from making any voluntary disclosure of information or documents related to any violation of law to any governmental agency or legislative body, or any self-regulatory organization, in each case,
without advance notice to the Company. 
 7. Assignment. This Agreement, and all of the terms and conditions hereof, shall bind the
Company and its successors and assigns and shall bind Executive and Executive’s heirs, executors and administrators. No transfer or assignment of this Agreement shall release the Company from any obligation to Executive hereunder incurred prior
to such assignment. Neither this Agreement, nor any of the Company’s rights or obligations hereunder, may be assigned or otherwise subject to hypothecation by Executive, and any such attempted assignment or hypothecation shall be null and void.
The Company may assign any of its rights hereunder, in whole or in part, to (i) any successor or assign in connection with the sale of all or substantially all of the Company’s assets or equity interests or in connection with any merger,
acquisition and/or reorganization or (ii) to EVE on or prior to the Closing Date or (iii) to Newco on or following the Closing Date. 

8. Arbitration. 
 (a)
Except as otherwise set forth in Section 6 of this Agreement, the Company and Executive mutually consent to the resolution by final and binding arbitration of any and all disputes, controversies or claims between them
including, without limitation, (i) any dispute, controversy or claim related in any way to Executive’s employment with the Company or any termination thereof, (ii) any dispute, controversy or claim of alleged discrimination,
harassment or retaliation (including, but not limited to, claims based on race, sex, sexual preference, religion, national origin, age, marital or family status, medical condition, handicap or disability) and (iii) any claim arising out of or
relating to this Agreement or the breach thereof (collectively, “Disputes”); provided, however, that nothing herein shall require arbitration of any claim or charge which, by law, cannot be the subject of a compulsory
arbitration agreement. All Disputes shall be resolved exclusively by arbitration administered by the Judicial Arbitration and Mediation Services (“JAMS”) under the JAMS Comprehensive Arbitration Rules & Procedures then in
effect, available at www.jamsadr.com (the “JAMS Rules”). 
 (b) Any arbitration proceeding brought under this Agreement
shall be conducted in Melbourne, Florida, or another mutually agreed upon location before one arbitrator selected in accordance with the JAMS Rules. The Company will pay for any administrative or hearing fees charged by the arbitrator or JAMS,
except that Executive shall pay any filing fees associated with any arbitration that Executive initiatives (but only so much of the filing fees as Executive would have instead paid, had Executive filed a complaint in a court of law). Each party to
any Dispute shall pay its own expenses, including attorneys’ fees; provided, that, the arbitrator shall award the prevailing party reasonable costs and attorneys’ fees incurred but shall not be able to award any special or
punitive damages. The arbitrator shall issue a decision or award in writing, stating the essential findings of fact and conclusions of law. 

 (c) Any judgment on or enforcement of any award, including an award providing for interim or
permanent injunctive relief, rendered by the arbitrator may be entered, enforced or appealed from in any court of competent jurisdiction. Any arbitration proceedings, decision or award rendered hereunder, and the validity, effect and interpretation
of this arbitration provision, shall be governed by the Federal Arbitration Act, 9 U.S.C. §1 et seq. 
 (d) It is part of the essence
of this Agreement that any Disputes hereunder shall be resolved expeditiously and as confidentially as possible. Accordingly, the Company and Executive agree that all proceedings in any arbitration shall be conducted under seal and kept strictly
confidential. In that regard, no party shall use, disclose or permit the disclosure of any information, evidence or documents produced by any other party in the arbitration proceedings or about the existence, contents or results of the proceedings
except as may be required by any legal process, as required in an action in aid of arbitration or for enforcement of or appeal from an arbitral award or as may be permitted by the arbitrator for the preparation and conduct of the arbitration
proceedings. Before making any disclosure permitted by the preceding sentence, the party intending to make such disclosure shall give the other party reasonable written notice of the intended disclosure and afford such other party a reasonable
opportunity to protect its interests. 
 ______ By initialing here, Executive acknowledges he or she has read this paragraph and agrees with the
arbitration provision herein. 
 9. General. 

(a) Notices. All notices, requests, consents, claims, demands, waivers and other communications hereunder shall be in writing and shall

or e-mail; or (iv) on the third (3rd) day after the date mailed, by certified or registered mail, return receipt requested, postage prepaid. Such
communications must be sent to the respective parties at the following addresses (or at such other address for a party as shall be specified in a notice given in accordance with this Section 9(a)): 

To the Company: 
 To Executive:

 At the address shown in the Company’s personnel records. 

(b) Entire Agreement. This Agreement (including any Exhibits hereto) constitutes the sole and entire agreement of the parties to this
Agreement with respect to the subject matter contained herein and therein, and, effective as of the Effective Date, supersedes all prior and contemporaneous representations, warranties, understandings and agreements, both written and oral, with
respect to such subject matter. 
 (c) Headings. The headings in this Agreement are for reference only and shall not affect the
interpretation of this Agreement. 

 (d) Amendment and Modification; Waiver. This Agreement may only be amended, modified
or supplemented by an agreement in writing signed by all of the parties hereto. No failure to exercise, or delay in exercising, any right, remedy, power or privilege arising from this Agreement shall operate or be construed as a waiver thereof; nor
shall any single or partial exercise of any right, remedy, power or privilege hereunder preclude any other or further exercise thereof or the exercise of any other right, remedy, power or privilege. 

(e) Governing Law. This Agreement shall be governed by and construed in accordance with the internal laws of the State of Florida
without giving effect to any choice or conflict of law provision or rule. 
 (f) Survivorship. The provisions of this Agreement
necessary to carry out the intention of the parties as expressed herein shall survive the termination or expiration of this Agreement, including without limitation, the provisions of Section 6 hereof. 

(g) No Third-Party Beneficiaries. This Agreement is for the sole benefit of the parties hereto and their respective successors and
permitted assigns and nothing herein, express or implied, is intended to or shall confer upon any other Person or entity any legal or equitable right, benefit or remedy of any nature whatsoever under or by reason of this Agreement. 

(h) Construction. The parties acknowledge that this Agreement is the result of
arm’s-length negotiations between sophisticated parties, each afforded representation by legal counsel. Each and every provision of this Agreement shall be construed as though both parties participated
equally in the drafting of the same, and any rule of construction that a document shall be construed against the drafting party shall not be applicable to this Agreement. 

(i) Withholding. All compensation payable to Executive pursuant to this Agreement shall be subject to any applicable statutory
withholding taxes and such other taxes as are required or permitted under applicable law and such other deductions or withholdings as authorized by Executive to be collected with respect to compensation paid to Executive. 

(j) Section 409A. The intent of the parties is that payments and benefits under this Agreement comply with, or be
exempt from, Section 409A of the Code, to the extent subject thereto, and accordingly, to the maximum extent permitted, this Agreement shall be interpreted and administered to be in compliance therewith. Notwithstanding anything contained
herein to the contrary, Executive shall not be considered to have terminated employment with the Company for purposes of any payments under this Agreement which are subject to Section 409A of the Code until Executive would be considered to have
incurred a “separation from service” from the Company Group within the meaning of Section 409A of the Code. Each amount to be paid or benefit to be provided under this Agreement shall be construed as a separate identified payment for
purposes of Section 409A of the Code. Without limiting the foregoing and notwithstanding anything contained herein to the contrary, to the extent required in order to avoid accelerated taxation and/or tax penalties under Section 409A of
the Code, amounts that would otherwise be payable and benefits that would otherwise be provided pursuant to this Agreement or any other arrangement between Executive and the Company Group during the six-month
period immediately following Executive’s separation from service shall instead be paid on the first business day after the date that is six months following Executive’s separation from service (or, if earlier, Executive’s date of
death). To the extent required to avoid an accelerated or additional tax under Section 409A 

 
of the Code, amounts reimbursable to Executive under this Agreement shall be paid to Executive on or before the last day of the year following the year in which the expense was incurred and the
amount of expenses eligible for reimbursement (and in kind benefits provided to Executive) during one year may not affect amounts reimbursable or provided in any subsequent year. The Company makes no representation that any or all of the payments
described in this Agreement shall be exempt from or comply with Section 409A of the Code and makes no undertaking to preclude Section 409A of the Code from applying to any such payment. 

(k) 280G Payments. In the event that any payment or benefit received or to be received by Executive, whether pursuant to the terms of
this Agreement or any other plan, arrangement or agreement (all such payments and benefits being hereinafter referred to as the “Total Payments”) would be subject, in whole or in part, to the excise tax imposed under
Section 4999 of the Code (the “Excise Tax”), then the Total Payments will be reduced (in a manner complying with Code Section 409A), but only to the extent that Executive would retain a greater amount on an after-tax basis than Executive would retain absent such reduction, such that the value of the Total Payments that Executive is entitled to receive will be $1 less than the maximum amount which Executive may receive
without becoming subject to the Excise Tax. 
 (l) No Mitigation. The Company agrees that, upon termination of Executive’s
employment hereunder, Executive is not required to seek other employment or to attempt in any way to reduce any amounts payable to Executive by the Company Group under this Agreement or otherwise. Further, no payment or benefit provided for in this
Agreement or elsewhere shall be reduced by any compensation earned by Executive as the result of employment by another employer. 
 (m)
Counterparts. This Agreement may be executed in counterparts, each of which shall be deemed an original, but all of which together shall be deemed to be one and the same agreement. A signed copy of this Agreement delivered by facsimile, e-mail or other means of electronic transmission shall be deemed to have the same legal effect as delivery of an original signed copy of this Agreement. 

10. Executive Representation and Acceptance. By signing this Agreement, Executive hereby represents that Executive is not currently
under any contractual obligation to work for another employer (other than as a board member of Zanite) and that Executive is not restricted by any agreement or arrangement from entering into this Agreement and performing Executive’s duties
hereunder. 
 11. Effect of Proposed Business Combination. It is the intent of the Parties to complete the possible Business
Combination and for Executive to serve as Co-CEO of Newco. As a result, the Parties shall take actions consistent with this intent including, but not limited to, Embraer causing the BCA to provide, or to cause
Newco to provide, that Newco shall assume and fully perform this Agreement.
