the tax that Executive would have paid had Executive not been subject to tax outside the United States (such reimbursements to be paid (net of taxes) within the timeframe required by Treasury
Regulation Section 1.409A-1(b)(8)(iii)) for so long as Executive is subject to additional tax solely due to Executive’s services as a foreign member of the Management Board of Parent, and

6. Termination. 

Executive’s employment hereunder may be terminated by the Company or Executive, as applicable, without any breach of this Agreement under
the following circumstances, and the Term will end on the Date of Termination. “Date of Termination” shall mean (i) if Executive’s employment is terminated by reason of Executive’s death, the date of Executive’s

	 	(b)	 Notice of Termination. Any termination of Executive’s employment by the Company or by Executive
under this Section 6 (other than termination pursuant to Section 6(a)(i)) shall be communicated by a written notice to the other Party hereto (i) indicating the specific termination provision in this Agreement relied upon, (ii)
setting forth in reasonable detail the facts and circumstances claimed to provide a basis for termination of Executive’s employment under the provision so indicated, if applicable, and (iii) specifying a Date of Termination which, if
submitted by Executive, shall be at least thirty (30) days following the date of such notice (a “Notice of Termination”); provided, however, that in the event that Executive delivers a Notice of Termination to the
Company, the Company may, in its sole discretion, change the Date of Termination to any date that occurs following the date of the Company’s receipt of such Notice of Termination and is prior to the date specified in such Notice of Termination,
but the termination will still be considered a resignation by Executive. A Notice of Termination submitted by the Company may provide for a Date of Termination on the date Executive receives the Notice of Termination, or any date thereafter elected
by the Company. The failure by either Party to set forth in the Notice of Termination any fact or circumstance which contributes to a showing of Cause or Good Reason shall not waive any right of the Party hereunder or preclude the Party from
asserting such fact or circumstance in enforcing the Party’s rights hereunder. 

  

	 	(c)	 Company Obligations upon Termination. Upon termination of Executive’s employment pursuant to any of
the circumstances listed in this Section 6, Executive (or Executive’s estate) shall be entitled to receive the sum of: (i) the portion of Executive’s Base Salary earned through the Date of Termination, but not yet paid to
Executive; (ii) any expense reimbursements owed to Executive pursuant to Section 5(d); and (iii) any vested benefits owed to Executive under any qualified retirement plan or health and welfare benefit plan in which Executive was a
participant in accordance with applicable law and the provisions of such plan. Except as otherwise expressly required by law (e.g., COBRA) or applicable plan, program, or arrangement or as specifically provided herein, all of Executive’s rights
to salary, severance, benefits, bonuses and other compensatory amounts hereunder (if any) shall cease upon the termination of Executive’s employment hereunder. In the event that Executive’s employment is terminated by the Company for any
reason, Executive’s sole and exclusive remedy shall be to receive the payments and benefits described in this Section 6(c) or Section 7, as applicable 

 

	 	(d)	 Deemed Resignation. If the Executive’s employment with Company terminates for any reason, Executive
shall be deemed to have resigned at that time from any and all positions that he may have held with Company or any Affiliates, as designated by Company or any Affiliates, or any other positions that he held on behalf of Company or any Affiliates.
If, for any reason, this Section 6(d) is deemed insufficient to effectuate such resignation, following a reasonable opportunity to review, Executive hereby authorizes Company and any Affiliates to execute any documents or instruments consistent
herewith which Company may deem necessary or desirable to effectuate such resignation or resignations, and to act as his attorney-in-fact. The Company will provide
Executive with a copy of such documents.

	 	(e)	 Mitigation. The Executive shall not be required to mitigate damages, or the amountof any payment
provided for under this Agreement by seeking other employment or otherwise after the termination of his employment hereunder, and any amounts earned by the Executive, whether from self-employment, as a common-law employee or otherwise, shall not reduce the amount of any payments under Section 7 otherwise payable to the Executive. For the avoidance of doubt, this Section 6(e) shall not affect
Section 7(b)(ii) or Section 7(c)(ii). 

  

	 	7.	 Payments upon Termination. 

 

	 	(a)	 Termination for Cause, or Termination Upon Death, Disability or Resignation from the Company Without Good

	 	(b)	 Termination without Cause, or Resignation from the Company with Good Reason. If Executive’s
employment is terminated by the Company without Cause pursuant to Section 6(a)(iv), or pursuant to Section 6(a)(v) due to Executive’s resignation with Good Reason, then except as otherwise provided under Section 7(c) and subject
to Executive signing on or before the 21st day following Executive’s Date of Termination, and not revoking, a release of claims substantially in the form attached as Exhibit A to this Agreement (the “Release”) and

of the cost of continuation coverage of group health coverage during the Severance Period; provided, that such reimbursement will cease if Executive receives coverage under a subsequent employer’s group health plan prior to the end of
such Severance Period, and provided, further, that, notwithstanding the foregoing, if the Company determines that it cannot provide the benefit required by this clause (b)(ii) without potentially violating applicable law or incurring
an excise tax, the Company shall in lieu thereof provide to Executive a taxable monthly payment in an amount equal to the monthly COBRA premium that Executive would be required to pay to continue Executive’s and the Executive’s covered
dependents’ group health coverage in effect on the Date of Termination (which amount shall 

  
 6 

 

 
  

 be based on the premium for the first month of COBRA coverage), which payments shall be made
regardless of whether Executive elects COBRA continuation coverage and shall commence in the month following the month in which the Date of Termination occurs and end on the earliest of (x) the last day of the Severance Period, (y) the
date that Executive and/or Executive’s covered dependents become no longer eligible for COBRA and (z) the date Executive becomes eligible to receive healthcare coverage from a subsequent employer (and Executive agrees to promptly notify
the Company of such eligibility); and

year in which the Date of Termination occurs. 
  

	 	(c)	 Change in Control. In lieu of the payments and benefits set forth in Section 7(b), in the event

twelve (12) month period following the Date of Termination; and 
 (iii) all unvested equity or equity-based awards that vest solely
based on the passage of time and are then held by the Executive under any Company equity compensation plans shall immediately become 100% vested (with any such awards that vest in whole or in part based on the attainment of performance-vesting
conditions being governed by the terms of the applicable award agreement), and the time period that the Executive may have to exercise any stock options shall be extended for a period equal to the shorter of (x) 12 months or (y) the remaining

reasonable cause with respect to such offense is made); 
 (ii) the Executive’s gross negligence, willful misconduct or repeated
insubordination with respect to the Company or any Affiliate; 
 (iii) the Executive’s use of alcohol or illegal drugs in a manner that
impairs the performance of the Executive’s obligations under this Agreement; 
 (iv) the Executive has engaged in misconduct that
violates any applicable state or federal law prohibiting workplace harassment, including but not limited to sexual harassment, and/or discrimination, or that violates any written policy of the Company adopted to prevent workplace harassment or
discrimination; 
 (v) the Executive’s engagement in conduct which the Executive knows or reasonably should have known would cause the
Company to violate any state or federal law; or 
 (vi) (A) repeated failure of Executive to substantially perform his employment duties
hereunder or (B) the Executive’s material breach of any of the material obligations of the Executive under this Agreement if such breach is not cured within five (5) days of notice of such breach to the Executive from the Board of
Directors. 
  

	 	(b)	 Change in Control. “Change in Control” shall have the following meaning for purposes of this
Agreement: 

 (i) any “person,” as such term is used in Sections 13(d) and 14(d) of the Securities Exchange Act
of 1934, as amended (the “Act”) (other than Parent, any Affiliate, or any trustee, fiduciary or other person or entity holding securities under any employee benefit plan or trust of Parent or any Affiliate), together with all
“affiliates” and “associates” (as such terms are defined in Rule 12b-2 under the Act) of such person, shall become the “beneficial owner” (as such term is defined in Rule 13d-3 under the Act), directly or indirectly, of securities of Parent representing fifty percent (50%) or more of the combined voting power of Parent’s then outstanding securities having the right to vote in an
election of the Board (“Voting Securities”) (in such case other than as a result of an acquisition of securities directly from Parent); or 

  
 8 

 

 
  

 (ii) the consummation of (A) any consolidation or merger of Parent where the
shareholders of Parent, immediately prior to the consolidation or merger, would not, immediately after the consolidation or merger, beneficially own (as such term is defined in Rule 13d-3 under the Act),
directly or indirectly, shares representing in the aggregate more than fifty percent (50%) of the voting shares of Parent issuing cash or securities in the consolidation or merger (or of its ultimate parent corporation, if any), or (B) any sale
or other transfer (in one transaction or a series of transactions contemplated or arranged by any party as a single plan) of all or substantially all of the assets of Parent. 

Notwithstanding the foregoing, a Change in Control shall not be deemed to have occurred (x) as a result of an initial public offering or
direct listing of Parent’s equity securities or other financing transaction, (y) as a result of a transaction that occurs to change the domicile of Parent, or (z) for purposes of the foregoing clause (i) solely as the result of
an acquisition of securities by Parent that, by reducing the number of shares of Voting Securities outstanding, increases the proportionate number of Voting Securities beneficially owned by any person to fifty percent (50%) or more of the combined
voting power of all of the then outstanding Voting Securities; provided, however, that if any person referred to in this sentence shall thereafter become the beneficial owner of any additional shares of Voting Securities (other than pursuant to a
stock split, stock dividend, or similar transaction or as a result of an acquisition of securities directly from Parent) and immediately thereafter beneficially owns fifty percent (50%) or more of the combined voting power of all of the then
outstanding Voting Securities, then a Change in Control shall be deemed to have occurred for purposes of the foregoing clause (i). Notwithstanding the foregoing, a Change in Control shall not have occurred unless the transaction or event
constituting the Change in Control would also constitute a “change in control event” (as defined in Treasury Regulation §1.409A-3(i)(5)) under Section 409A (defined below).

guidance promulgated thereunder. 

  

	 	(d)	 Disability. “Disability” shall mean termination because the Executive is unable due to a
physical or mental condition to perform the essential functions of his position with or without reasonable accommodation for six (6) months in the aggregate during any twelve (12) month period or based on the written certification by two
licensed physicians of the likely continuation of such condition for such period. This definition shall be interpreted and applied consistent with the Americans with Disabilities Act, the Family and Medical Leave Act, and other applicable law. In
the event Executive’s employment is terminated based on the Executive’s Disability, then the Executive shall not be entitled to any severance payments or benefits, except as provided in Section 6(c).  

  
 9 

 

 
  

	 	(e)	 Good Reason. “Good Reason” shall mean the Company’s material breach of any of the
material obligations of the Company under this Agreement. Notwithstanding the foregoing, no Good Reason will have occurred unless and until: (a) Executive resigns within ninety (90) days of Executive’s knowledge of the occurrence of
the facts and circumstances underlying the Good Reason event, (b) Executive has provided the Company, within sixty (60) days of Executive’s knowledge of the occurrence of the facts and circumstances underlying the Good Reason event,
written notice stating with specificity the applicable facts and circumstances underlying such finding of Good Reason; (c) the Company has had an opportunity to cure the same within thirty (30) days after the receipt of such notice; and
(d) the Company shall have failed to so cure within such period.

	 	(b)	 Noncompetition. During the Term and for a period of one (1) year after the Date of Termination,
Executive shall not, without the Company’s prior written consent, whether individually, as a director, manager, member, stockholder, partner, owner, employee, consultant, advisor, agent, or in any other capacity, other than on behalf of the
Company or any Affiliates, directly or indirectly, organize, establish, own, operate, manage, control, engage in, participate in, invest in, permit Executive’s name to be used by, act as a consultant or advisor to, render services for (alone or
in association with any person, firm, corporation or business organization), or otherwise assist any person that engages in any business which competes with any portion of the Competitive Business (as defined below) anywhere in the world.
Notwithstanding the prior sentence, nothing shall prevent Executive from owning, for passive investment purposes not intended to circumvent this Agreement, less than three percent (3%) of the publicly-traded
common equity securities of any such person. Executive agrees and acknowledges that the Executive has the means to support Executive and Executive’s dependents other than by violating the provisions of this clause (a), and the provisions of
this clause (a) will not impair such ability. For purposes of this Section 9, “Competitive Business” shall mean the research, development and/or commercialization (collectively, “Develop”) of any compound
that has psychedelic, entactogenic and/or oneirophrenic properties, which is being Developed for the treatment of a mental health disease or disorder, and which Development would be competitive to any business conducted by the Company or any
Affiliate or any business of which Executive knows the Company or any Affiliate has specific plans to engage in on the Date of Termination. 

  

	 	(c)	 Nonsolicitation. During the Term and for a period of two (2) years after the Date of Termination,
Executive will not directly or indirectly (i) solicit any individual who, at the time of the solicitation is, or within the six (6) month prior to the Date of Termination was, an employee of or consultant to Company or any Affiliate to
terminate his or her relationship with the Company or any Affiliate; or (ii) attempt to induce any clients, licensors, licensees or customers of Company or any Affiliate to terminate, breach or materially change any contractual or other
relationship with Company or any Affiliate. 

  
 10 

 

 
  

	 	(d)	 Use of Material Undisclosed Information. The Executive acknowledges that it is the policy of the Company
that all employees are prohibited from benefiting from the possession of material undisclosed information concerning the Company or any Affiliates, providers or business partners (in each case provided they are listed on a national or international
securities exchange) with respect to trading in the public securities markets. The Executive covenants and agrees that he will abide by such policy. 

  

	 	(e)	 Reasonable Restrictions. The Executive further acknowledges and agrees that the provisions of this
Section 9 are reasonable and properly required for the adequate protection of the Competitive Business. Executive represents and warrants that (i) the restrictive provisions of this Section 9 will not substantially impair
Executive’s ability to earn a livelihood, nor will such provisions cause Executive undue hardship, and (ii) Executive has fully and carefully read this Agreement and has been advised by the Company to consult with an attorney of
Executive’s choice and that Executive fully understands and agrees with the provisions of this Agreement, including this Section 9. 

  

	 	(f)	 Blue Penciling. If, at the time of enforcement of any of the provisions of this Section 9, a court
shall hold that the duration, scope, geographic area or other restrictions stated herein are unreasonable under circumstances then existing, Executive and the Company agree that the maximum duration, scope, geographic area or other restrictions
deemed reasonable under such circumstances by such court shall be substituted for the stated duration, scope, geographic area or other restrictions. 

  

	 	10.	 Cooperation. 

  

	 	(a)	 Third-Party Agreements and Rights. The Executive hereby
confirms that the Executive is not bound by the terms of any agreement with any previous employer or other party which restricts in any way the Executive’s use or disclosure of information or the Executive’s engagement in any business. The
Executive represents to the Company that the Executive’s execution of this Agreement, the Executive’s continued employment with the Company and the performance of the Executive’s duties for the Company or any Affiliates will not
violate any obligations the Executive may have to any such previous employer or other party. In the Executive’s work for the Company or any Affiliates, the Executive will not disclose or make use of any information in violation of any
agreements with or rights of any such previous employer or other party, and the Executive will not bring to the premises of the Company or any Affiliates any copies or other tangible embodiments of non-public
information belonging to or obtained from any such previous employment or other party. 

  
 11 

 

 
  

	 	(b)	 Litigation and Regulatory Cooperation. During and after the Executive’s employment with the
Company, the Executive shall reasonably cooperate with the Company and any Affiliate in the defense or prosecution of any claims or actions now in existence or that may be brought in the future against or on behalf of the Company or any Affiliate
that relate to events or occurrences that transpired while the Executive was employed by the Company provided that such cooperation after the termination of Executive’s employment with the Company does not otherwise interfere with the
Executive’s subsequent employment and/or engagement with a subsequent employer and/or third parties. The Executive’s reasonable cooperation in connection with such claims or actions shall include, but not be limited to, being available to
meet with counsel to prepare for discovery or trial and to act as a witness on behalf of the Company and any Affiliate at mutually convenient times. During and after the Term, the Executive also shall cooperate reasonably with the Company and any
Affiliate in connection with any investigation or review of any federal, state or local regulatory authority as any such investigation or review relates to events or occurrences that transpired while the Executive was employed by the Company. The
Company or the applicable Affiliate shall reimburse the Executive for any reasonable out-of-pocket expenses (including reasonable legal fees) incurred in connection with
the Executive’s performance of obligations pursuant to this Section 10(b). 

  

	 	(c)	 Injunction. The Executive acknowledges that any material breach by him of his obligations under this
Agreement, including but not limited to the restrictions set forth in Section 9 hereof, would result in irreparable injury to the Company or an Affiliate. The Company or the applicable Affiliate shall, therefore, be entitled, without
restricting the Company or such applicable Affiliate(s) from other legal and equitable remedies, to injunctive and other equitable relief to prevent or restrain the breach of this Agreement and to withhold compensation and benefits from the
Executive if he fails to comply with this Agreement. Nothing in this Section shall be deemed to restrict any other remedy or right the Company, any Affiliate or the Executive may have for any other breach of this Agreement. 

 

	 	(d)	 Consent to Jurisdiction. To the extent that any court action is permitted consistent with or to enforce
Section 9 of this Agreement, the Parties hereby consent to the jurisdiction of the State of New York and County of New York. Accordingly, with respect to any such court action, the Executive (a) submits to the personal jurisdiction of such

 14. Advice of Counsel. The Executive acknowledges that, in
executing this Agreement, the Executive has had the opportunity to seek the advice of independent legal counsel, and has read and understood all of the terms and provisions of this Agreement. This Agreement shall not be construed against any Party
by reason of the drafting or preparation hereof. 
 15. Section 409A. This Agreement is intended to comply with the requirements of
Section 409A of the Internal Revenue Code of 1986, as amended (“Section 409A”), and the Parties hereby agree to amend this Agreement as and when necessary or desirable to conform to or otherwise properly
reflect any guidance issued under Section 409A after the date hereof without violating Section 409A. In case any one or more provisions of this Agreement fails to comply with the provisions of Section 409A, the remaining provisions of
this Agreement shall remain in effect, and this Agreement shall be administered and applied as if the non-complying provisions were not part of this Agreement. The Parties in that event shall endeavor to agree
upon a reasonable substitute for the non-complying provisions, to the extent that a substituted provision would not cause this Agreement to fail to comply with Section 409A, and, upon so agreeing, shall
incorporate such substituted provisions into this Agreement. A termination of the Executive’s employment 

  
 13 

 

 
  

 
hereunder shall not be deemed to have occurred for purposes of any provision of this Agreement providing for the payment of any amount or benefit constituting “deferred compensation”
under Section 409A upon or following a termination of employment unless such termination is also a “separation from service” within the meaning of Section 409A and, for purposes of any such provision of this Agreement, references
to a “termination,” “termination of employment” or like terms shall mean “separation from service.” In the event that any payment or benefit made hereunder or under any compensation plan, program or arrangement of the
Company would constitute payments or benefits pursuant to a non-qualified deferred compensation plan within the meaning of Section 409A and, at the time of the Executive’s “separation from
service” the Executive is a “specified employee” within the meaning of Section 409A, then any such payments or benefits shall be delayed until the six-month anniversary of the date of
Executive’s “separation from service”. Each payment made under this Agreement shall be designated as a “separate payment” within the meaning of Section 409A. All reimbursements and
in-kind benefits provided under this Agreement shall be made or provided in accordance with the requirements of Section 409A to the extent that such reimbursements or
in-kind benefits are subject to Section 409A. All reimbursements for expenses paid pursuant hereto that constitute taxable income to the Executive shall in no event be paid later than the end of the
calendar year next following the calendar year in which the Executive incurs such expense or pays such related tax. Unless otherwise permitted by Section 409A, the right to reimbursement or in-kind
benefits under this Agreement shall not be subject to liquidation or exchange for another benefit and the amount of expenses eligible for reimbursement, or in-kind benefits, provided during any taxable year
shall not affect the expenses eligible for reimbursement, or in-kind benefits to be provided, respectively, in any other taxable year. 
  

	 	16.	 Section 280G. 

 

	 	(a)	 Notwithstanding anything contained in this Agreement to the contrary, in the event that any payment or benefit
received or to be received by the 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 part), to the excise tax imposed under Section 4999 of the Code (the “Excise Tax”), then, after taking into account any reduction in the Total Payments provided by reason of Section 280G of the Code
in any other plan, arrangement or agreement, then such remaining Total Payments shall be reduced, to the extent necessary so that no portion of the Total Payments is subject to the Excise Tax but only if (i) the net amount of such Total
Payments, as so reduced (and after subtracting the net amount of federal, state and local income taxes on such reduced Total Payments and after taking into account the phase out of itemized deductions and personal exemptions attributable to such
reduced Total Payments) is greater than or equal to (ii) the net amount of such Total Payments without such reduction (but after subtracting the net amount of federal, state and local income taxes on such Total Payments and the amount of Excise
Tax to which Executive would be subject in respect of such unreduced Total Payments and after taking into account the phase out of itemized deductions and personal exemptions attributable to such unreduced Total Payments). 

  
 14 

 

 
  

	 	(b)	 For purposes of determining whether and the extent to which the Total Payments will be subject to the Excise
Tax, (i) no portion of the Total Payments the receipt or enjoyment of which Executive shall have waived at such time and in such manner as not to constitute a “payment” within the meaning of Section 280G(b) of the Code shall be
taken into account; (ii) no portion of the Total Payments shall be taken into account which, in the written opinion of an independent, nationally recognized accounting firm (the “Independent Advisors”) selected by the Company,
does not constitute a “parachute payment” within the meaning of Section 280G(b)(2) of the Code (including by reason of Section 280G(b)(4)(A) of the Code) and, in calculating the Excise Tax, no portion of such Total Payments shall
be taken into account which, in the opinion of Independent Advisors, constitutes reasonable compensation for services actually rendered, within the meaning of Section 280G(b)(4)(B) of the Code, in excess of the “base amount” (as
defined in Section 280G(b)(3) of the Code) allocable to such reasonable compensation; and (iii) the value of any non-cash benefit or any deferred payment or benefit included in the Total Payments
shall be determined by the Independent Advisors in accordance with the principles of Sections 280G(d)(3) and (4) of the Code. 

  

	 	17.	 Miscellaneous. 

 

	 	(a)	 This Agreement shall be governed by, and construed exclusively in accordance with, the laws of the State of New
York without giving effect to any choice or conflict of law rules to the contrary. Each Party submits to the nonexclusive jurisdiction of any United States District Court located in New York, New York and of any New York state court sitting in New
York, New York for purposes of all legal proceedings arising out of or relating to this Agreement or the transactions contemplated hereby. Each Party irrevocably waives any objection which it may now or hereafter have to the laying of venue in any
proceeding brought in such a court, and any claim that any such proceeding was brought in an inconvenient forum. 

  

	 	(b)	 Should any provision of this Agreement be held invalid or unenforceable, the remainder of this Agreement shall
not be affected and shall be enforceable to the fullest extent permitted at law or in equity. 

  

	 	(c)	 This Agreement contains the entire agreement between the Parties concerning the subject matter hereof and
supersedes all prior conversations, proposals, negotiations, understandings and agreements, whether written or oral, concerning the subject matter hereof, including, without limitation, the Prior Agreement. 

 

	 	(d)	 This Agreement shall not be amended, altered, changed, modified, supplemented or rescinded in any manner except
by written agreement executed by both Parties expressly referring to this Agreement. 

  

	 	(e)	 No waiver of any provision hereof shall be effective unless made in writing and signed by the waiving Party.
The failure of any Party to require the performance of any term or obligation of this Agreement, or the waiver by any Party of any breach of this Agreement, shall not prevent any subsequent enforcement of such term or obligation or be deemed a
waiver of any subsequent breach. 

  
 15 

 

 
  

	 	(f)	 This Agreement may be executed in any number of counterparts, each of which when so executed and delivered
shall be taken to be an original; but such counterparts shall together constitute one and the same document. 

  

	 	(g)	 The Parties recognize that litigation in federal or state courts or before federal or state administrative
agencies of disputes arising out of the Executive’s employment with the Company or out of this Agreement, or the Executive’s termination of employment or termination of this Agreement, may not be in the best interests of either the
Executive or the Company, and may result in unnecessary costs, delays, complexities, and uncertainty. The Parties agree that any dispute between the Parties arising out of or relating to the negotiation, execution, performance or termination of this
Agreement or the Executive’s employment, including, but not limited to, any claim arising out of this Agreement, claims under Title VII of the Civil Rights Act of 1964, as amended, the Civil Rights Act of 1991, the Age Discrimination in
Employment Act of 1967, the Americans with Disabilities Act of 1990, Section 1981 of the Civil Rights Act of 1966, as amended, the Family Medical Leave Act, the Executive Retirement Income Security Act, and any similar federal, state or local
law, statute, regulation, or any common law doctrine, whether that dispute arises during or after employment, shall be settled by binding arbitration in accordance with the National Rules for the Resolution of Employment Disputes of the American
Arbitration Association; provided, however, that this dispute resolution provision shall not apply to any separate agreements between the Parties that do not themselves specify arbitration as an exclusive remedy. The location
for the arbitration shall be the New York metropolitan area. Any award made by such panel shall be final, binding and conclusive on the Parties for all purposes, and judgment upon the award rendered by the arbitrators may be entered in any court
having jurisdiction thereof. The arbitrators’ fees and expenses and all administrative fees and expenses associated with the filing of the arbitration shall be borne by the Company; provided, however, that at the Executive’s
option, Executive may voluntarily pay up to one-half the costs and fees. The Parties acknowledge and agree that their obligations to arbitrate under this Section survive the termination of this Agreement and
continue after the termination of the employment relationship between Executive and the Company. The Parties each further agree that the arbitration provisions of this Agreement shall provide each Party with its exclusive remedy, and each Party
expressly waives any right it might have to seek redress in any other forum, except as otherwise expressly provided in this Agreement. By election arbitration as the means for final settlement of all claims, the Parties hereby waive their
respective rights to, and agree not to, sue each other in any action in a Federal, State or local court with respect to such claims, but may seek to enforce in court an arbitration award rendered pursuant to this Agreement. The Parties specifically
agree to waive their respective rights to a trial by jury, and further agree that no demand, request or motion will be made for trial by jury.

 (iii) Termination for Cause. The Company may terminate Executive’s
employment for Cause, as defined below. 
 (iv) Termination without Cause. The Company may terminate Executive’s employment
without Cause. 
 (v) Resignation from the Company with Good Reason. Executive may resign Executive’s employment with the
Company with Good Reason, as defined below. 
 (vi) Resignation from the Company without Good Reason. Executive may resign
Executive’s employment with the Company for any reason other than Good Reason or for no reason. 
  

	 	(b)	 Notice of Termination. Any termination of Executive’s employment by the Company or by Executive
under this Section 6 (other than termination pursuant to Section 6(a)(i)) shall be communicated by a written notice to the other Party hereto (i) indicating the specific termination provision in this Agreement relied upon,
(ii) setting forth in reasonable detail the facts and circumstances claimed to provide a basis for termination of Executive’s employment under the provision so indicated, if applicable, and (iii) specifying a Date of Termination
which, if submitted by Executive, shall be at least thirty (30) days following the date of such notice (a “Notice of Termination”); provided, however, that in the event that Executive delivers a Notice of
Termination to the Company, the Company may, in its sole discretion, change the Date of Termination to any date that occurs following the date of the Company’s receipt of such Notice of Termination and is prior to the date specified in such
Notice of Termination, but the termination will still be considered a resignation by Executive. A Notice of Termination submitted by the Company may provide for a Date of Termination on the date Executive receives the Notice of Termination, or any
date thereafter elected by the Company. The failure by either Party to set forth in the Notice of Termination any fact or circumstance which contributes to a showing of Cause or Good Reason shall not waive any right of the Party hereunder or
preclude the Party from asserting such fact or circumstance in enforcing the Party’s rights hereunder. 

  

	 	(c)	 Company Obligations upon Termination. Upon termination of Executive’s employment pursuant to any of
the circumstances listed in this Section 6, Executive (or Executive’s estate) shall be entitled to receive the sum of: (i) the portion of Executive’s Base Salary earned through the Date of Termination, but not yet paid to
Executive; (ii) any expense reimbursements owed to Executive pursuant to Section 5(d); and (iii) any vested benefits owed to Executive under any qualified retirement plan or health and welfare benefit plan in which Executive was a
participant in accordance with applicable law and the provisions of such plan. Except as otherwise expressly required by law (e.g., COBRA) or applicable plan, program, or arrangement or as specifically provided herein, all of Executive’s rights
to salary, severance, benefits, bonuses and other compensatory amounts hereunder (if any) shall cease upon the termination of Executive’s employment hereunder. In the event that Executive’s employment is terminated by the Company for any
reason, Executive’s sole and exclusive remedy shall be to receive the payments and benefits described in this Section 6(c) or Section 7, as applicable 

  
 4 

 

 
  

	 	(d)	 Deemed Resignation. If the Executive’s employment with Company terminates for any reason, Executive
shall be deemed to have resigned at that time from any and all positions that he may have held with Company or any Affiliates, as designated by Company or any Affiliates, or any other positions that he held on behalf of Company or any Affiliates.
If, for any reason, this Section 6(d) is deemed insufficient to effectuate such resignation, following a reasonable opportunity to review, Executive hereby authorizes Company and any Affiliates to execute any documents or instruments consistent
herewith which Company may deem necessary or desirable to effectuate such resignation or resignations, and to act as his attorney-in-fact. The Company will provide
Executive with a copy of such documents. 

  

	 	(e)	 Mitigation. The Executive shall not be required to mitigate damages, or the amount of any payment
provided for under this Agreement by seeking other employment or otherwise after the termination of his employment hereunder, and any payments earned by the Executive, whether from self-employment, as a common-law employee or otherwise, shall not reduce the amount of any amounts under Section 7 otherwise payable to the Executive. For the avoidance of doubt, this Section 6(e) shall not affect
Section 7(b)(ii) or Section 7(c)(ii). 

 7. Payments upon Termination. 

 

	 	(a)	 Termination for Cause, or Termination Upon Death, Disability or Resignation from the Company Without Good
Reason. If Executive’s employment shall terminate as a result of Executive’s death pursuant to Section 6(a)(i) or Disability pursuant to Section 6(a)(ii), pursuant to Section 6(a)(iii) for Cause, or pursuant to
Section 6(a)(vi) for Executive’s resignation from the Company without Good Reason, then Executive shall not be entitled to any severance payments or benefits, except as provided in Section 6(c). 

 

	 	(b)	 Termination without Cause, or Resignation from the Company with Good Reason. If Executive’s
employment is terminated by the Company without Cause pursuant to Section 6(a)(iv), or pursuant to Section 6(a)(v) due to Executive’s resignation with Good Reason, then except as otherwise provided under Section 7(c) and subject
to Executive signing on or before the 21st day following Executive’s Date of Termination, and not revoking, a release of claims substantially in the form attached as Exhibit A to this Agreement (the “Release”) and
Executive’s continued compliance with Section 9, Executive shall receive, in addition to payments and benefits set forth in Section 6(c), the following: 

  
 5 

 

 
  

 (i) an amount equal to 0.75 times the Executive’s then-current Base Salary, payable in
the form of salary continuation in regular installments over the nine (9) month period following the Date of Termination (the “Severance Period”) in accordance with the Company’s normal payroll practices; 

(ii) subject to Executive’s eligibility and election of continuation coverage of group health coverage pursuant to COBRA, reimbursement
of the cost of continuation coverage of group health coverage during the Severance Period; provided, that such reimbursement will cease if Executive receives coverage under a subsequent employer’s group health plan prior to the end of such
Severance Period, and provided, further, that, notwithstanding the foregoing, if the Company determines that it cannot provide the benefit required by this clause (b)(ii) without potentially violating applicable law or incurring an excise tax, the
Company shall in lieu thereof provide to Executive a taxable monthly payment in an amount equal to the monthly COBRA premium that Executive would be required to pay to continue Executive’s and the Executive’s covered dependents’ group
health coverage in effect on the Date of Termination (which amount shall be based on the premium for the first month of COBRA coverage), which payments shall be made regardless of whether Executive elects COBRA continuation coverage and shall
commence in the month following the month in which the Date of Termination occurs and end on the earliest of (x) the last day of the Severance Period, (y) the date that Executive and/or Executive’s covered dependents become no longer
eligible for COBRA and (z) the date Executive becomes eligible to receive healthcare coverage from a subsequent employer (and Executive agrees to promptly notify the Company of such eligibility); and 

(iii) the earned but unpaid portion of the Annual Bonus, if any, for any calendar year ending prior to the calendar year in which the Date of
Termination occurs (as determined by the Board in good faith for the performance year), which amount will be paid no later than April 30th of the year in which the Date of Termination occurs.

  

	 	(c)	 Change in Control. In lieu of the payments and benefits set forth in Section 7(b), in the event
Executive’s employment is terminated by the Company without Cause pursuant to Section 6(a)(iv), or pursuant to Section 6(a)(v) due to Executive’s resignation with Good Reason, in either case, on or within twelve (12) months
following the date of a Change in Control, subject to Executive signing on or before the 21st day following Executive’s Date of Termination, and not revoking, the Release and Executive’s continued compliance with Section 9, Executive
shall receive, in lieu of the payments and benefits set forth in Section 7(b), the following: 

  
 6 

 

 
  

 (i) an amount in cash equal to the sum of (A) 12 months of the Executive’s then-current
Base Salary, and (B) the then-current Target Bonus, payable in a lump sum within sixty (60) days following the Date of Termination; 

(ii) the benefits set forth in Section 7(b)(ii), provided that solely for this purpose, “Severance Period” shall mean the
twelve (12) month period following the Date of Termination; and 
 (iii) all unvested equity or equity-based awards that vest solely
based on the passage of time and are then held by the Executive under any Company equity compensation plans shall immediately become 100% vested (with any such awards that vest in whole or in part based on the attainment of performance-vesting
conditions being governed by the terms of the applicable award agreement), and the time period that the Executive may have to exercise any stock options shall be extended for a period equal to the shorter of (x) 12 months or (y) the remaining
term of the applicable stock option. 
 8. Certain Definitions. 

 

	 	(a)	 Cause. The Company shall have “Cause” to terminate Executive’s employment hereunder upon:

 (i) the commission by the Executive of, or indictment of the Executive for, (A) a felony or (B) any
misdemeanor involving moral turpitude, deceit, or intentional fraud (“indictment,” for these purposes, meaning an indictment, probable cause hearing or any other procedure pursuant to which an initial determination of probable or
reasonable cause with respect to such offense is made); 
 (ii) the Executive’s gross negligence, willful misconduct or repeated
insubordination with respect to the Company or any Affiliate; 
 (iii) the Executive’s use of alcohol or illegal drugs in a manner that
impairs the performance of the Executive’s obligations under this Agreement; 
 (iv) the Executive has engaged in misconduct that
violates any applicable state or federal law prohibiting workplace harassment, including but not limited to sexual harassment, and/or discrimination, or that violates any written policy of the Company adopted to prevent workplace harassment or
discrimination; 
 (v) the Executive’s engagement in conduct which the Executive knows or reasonably should have known would cause the
Company to violate any state or federal law; or 

  
 7 

 

 
  

 (vi) (A) repeated failure of Executive to substantially perform his employment duties
hereunder or (B) the Executive’s material breach of any of the material obligations of the Executive under this Agreement if such breach is not cured within fifteen (15) days of notice of such breach to the Executive from the Board of
Directors. 
  

	(b)	 Change in Control. “Change in Control” shall have the following meaning for purposes of this
Agreement: 

 (i) any “person,” as such term is used in Sections 13(d) and 14(d) of the Securities Exchange Act
of 1934, as amended (the “Act”) (other than Parent, any Affiliate, or any trustee, fiduciary or other person or entity holding securities under any employee benefit plan or trust of Parent or any Affiliate), together with all
“affiliates” and “associates” (as such terms are defined in Rule 12b-2 under the Act) of such person, shall become the “beneficial owner” (as such term is defined in Rule 13d-3 under the Act), directly or indirectly, of securities of Parent representing fifty percent (50%) or more of the combined voting power of Parent’s then outstanding securities having the right to vote in an
election of the Board (“Voting Securities”) (in such case other than as a result of an acquisition of securities directly from Parent); or 

(ii) the consummation of (A) any consolidation or merger of Parent where the shareholders of Parent, immediately prior to the
consolidation or merger, would not, immediately after the consolidation or merger, beneficially own (as such term is defined in Rule 13d-3 under the Act), directly or indirectly, shares representing in the
aggregate more than fifty percent (50%) of the voting shares of Parent issuing cash or securities in the consolidation or merger (or of its ultimate parent corporation, if any), or (B) any sale or other transfer (in one transaction or a series
of transactions contemplated or arranged by any party as a single plan) of all or substantially all of the assets of Parent. 

Notwithstanding the foregoing, a Change in Control shall not be deemed to have occurred (x) as a result of an initial public offering or
direct listing of Parent’s equity securities or other financing transaction, (y) as a result of a transaction that occurs to change the domicile of Parent, or (z) for purposes of the foregoing clause (i) solely as the result of
an acquisition of securities by Parent that, by reducing the number of shares of Voting Securities outstanding, increases the proportionate number of Voting Securities beneficially owned by any person to fifty percent (50%) or more of the combined
voting power of all of the then outstanding Voting Securities; provided, however, that if any person referred to in this sentence shall thereafter become the beneficial owner of any additional shares of Voting Securities (other than pursuant to a
stock split, stock dividend, or similar transaction or as a result of an acquisition of securities directly from Parent) and immediately thereafter beneficially owns fifty percent (50%) or more of the combined voting power of all of the then
outstanding Voting Securities, then a Change in Control shall be deemed to have occurred for purposes of the foregoing clause (i). Notwithstanding the foregoing, a Change in Control shall not have occurred unless the transaction or event
constituting the Change in Control would also constitute a “change in control event” (as defined in Treasury Regulation §1.409A-3(i)(5)) under Section 409A (defined below). 

  
 8 

 

 
  

	 	(c)	 Code. “Code” shall mean the Internal Revenue Code of 1986, as amended, and the regulations and
guidance promulgated thereunder. 

  

	 	(d)	 Disability. “Disability” shall mean termination because the Executive is unable due to a
physical or mental condition to perform the essential functions of his position with or without reasonable accommodation for nine (9) months in the aggregate during any twelve (12) month period or based on the written certification by two
licensed physicians of the likely continuation of such condition for such period. This definition shall be interpreted and applied consistent with the Americans with Disabilities Act, the Family and Medical Leave Act, and other applicable law. In
the event Executive’s employment is terminated based on the Executive’s Disability, then the Executive shall not be entitled to any severance payments or benefits, except as provided in Section 6(c).  

 

	 	(e)	 Good Reason. “Good Reason” shall mean the Company’s material breach of any of the
material obligations of the Company under this Agreement. Notwithstanding the foregoing, no Good Reason will have occurred unless and until: (a) Executive resigns within ninety (90) days of Executive’s knowledge of the occurrence of
the facts and circumstances underlying the Good Reason event, (b) Executive has provided the Company, within sixty (60) days of Executive’s knowledge of the occurrence of the facts and circumstances underlying the Good Reason event,
written notice stating with specificity the applicable facts and circumstances underlying such finding of Good Reason; (c) the Company has had an opportunity to cure the same within thirty (30) days after the receipt of such notice; and
(d) the Company shall have failed to so cure within such period. 

  

	 	9.	 Restrictive Covenants. 

 

	 	(a)	 Confidentiality. The Parties have previously executed that certain proprietary Confidentiality and
Developments Agreement, dated as of April 1, 2019 (the “Confidentiality and Developments Agreement”), which remains in full force and effect and is hereby made a part of, this Agreement. 

 

	 	(b)	 Nonsolicitation. During the Term and for a period of twelve (12) months after the Date of
Termination, Executive will not directly or indirectly (i) solicit any individual who, at the time of the solicitation is, or within the six (6) month prior to the Date of Termination was, an employee of or consultant to Company or any
Affiliate to terminate his or her relationship with the Company or any Affiliate; or (ii) attempt to induce any clients, licensors, licensees or customers of Company or any Affiliate to terminate, breach or materially change any contractual or
other relationship with Company or any Affiliate. 

  
 9 

 

 
  

	 	(c)	 Use of Material Undisclosed Information. The Executive acknowledges that it is the policy of the Company
that all employees are prohibited from benefiting from the possession of material undisclosed information concerning the Company or any Affiliates, providers or business partners (in each case provided they are listed on a national or international
securities exchange) with respect to trading in the public securities markets. The Executive covenants and agrees that he will abide by such policy. 

  

	 	(d)	 Reasonable Restrictions. The Executive further acknowledges and agrees that the provisions of this
Section 9 are reasonable and properly required for the adequate protection of the Company’s business. Executive represents and warrants that (i) the restrictive provisions of this Section 9 will not substantially impair
Executive’s ability to earn a livelihood, nor will such provisions cause Executive undue hardship, and (ii) Executive has fully and carefully read this Agreement and has been advised by the Company to consult with an attorney of
Executive’s choice and that Executive fully understands and agrees with the provisions of this Agreement, including this Section 9. 

  

	 	(e)	 Blue Penciling. If, at the time of enforcement of any of the provisions of this Section 9, a court
shall hold that the duration, scope, geographic area or other restrictions stated herein are unreasonable under circumstances then existing, Executive and the Company agree that the maximum duration, scope, geographic area or other restrictions
deemed reasonable under such circumstances by such court shall be substituted for the stated duration, scope, geographic area or other restrictions. 

  

	 	10.	 Cooperation. 

  

	 	(a)	 Third-Party Agreements and Rights. The Executive hereby
confirms that the Executive is not bound by the terms of any agreement with any previous employer or other party which restricts in any way the Executive’s use or disclosure of information or the Executive’s engagement in any business. The
Executive represents to the Company that the Executive’s execution of this Agreement, the Executive’s continued employment with the Company and the performance of the Executive’s duties for the Company or any Affiliates will not
violate any obligations the Executive may have to any such previous employer or other party. In the Executive’s work for the Company or any Affiliates, the Executive will not disclose or make use of any information in violation of any
agreements with or rights of any such previous employer or other party, and the Executive will not bring to the premises of the Company or any Affiliates any copies or other tangible embodiments of non-public
information belonging to or obtained from any such previous employment or other party. 

  

	 	(b)	 Litigation and Regulatory Cooperation. During and after the Executive’s employment with the
Company, the Executive shall reasonably cooperate with the Company and any Affiliate in the defense or prosecution of any claims or actions now in existence or that may be brought in the future against or on behalf of the Company or any Affiliate
that relate to events or occurrences that transpired while the Executive was employed by the Company provided that such cooperation after the termination of Executive’s employment with the Company does not otherwise 

  
 10 

 

 
  

 interfere with the Executive’s subsequent employment and/or engagement with a
subsequent employer and/or third parties. The Executive’s reasonable cooperation in connection with such claims or actions shall include, but not be limited to, being available to meet with counsel to prepare for discovery or trial and to act
as a witness on behalf of the Company and any Affiliate at mutually convenient times. During and after the Term, the Executive also shall cooperate reasonably with the Company and any Affiliate in connection with any investigation or review of any
federal, state or local regulatory authority as any such investigation or review relates to events or occurrences that transpired while the Executive was employed by the Company. The Company or the applicable Affiliate shall reimburse the Executive
for any reasonable out-of-pocket expenses (including reasonable legal fees) incurred in connection with the Executive’s performance of obligations pursuant to this
Section 10(b). 
  

	 	(c)	 Injunction. The Executive acknowledges that any material breach by him of his obligations under this
Agreement, including but not limited to the restrictions set forth in Section 9 hereof, would result in irreparable injury to the Company or an Affiliate. The Company or the applicable Affiliate shall, therefore, be entitled, without
restricting the Company or such applicable Affiliate(s) from other legal and equitable remedies, to injunctive and other equitable relief to prevent or restrain the breach of this Agreement and to withhold compensation and benefits from the
Executive if he fails to comply with this Agreement. Nothing in this Section shall be deemed to restrict any other remedy or right the Company, any Affiliate or the Executive may have for any other breach of this Agreement. 

 

	 	(d)	 Consent to Jurisdiction. To the extent that any court action is permitted consistent with or to enforce
Section 9 of this Agreement, the Parties hereby consent to the jurisdiction of the State of New York and County of New York. Accordingly, with respect to any such court action, the Executive (a) submits to the personal jurisdiction of such
courts; (b) consents to service of process; and (c) waives any other requirement (whether imposed by statute, rule of court, or otherwise) with respect to personal jurisdiction or service of process. 

11. Assignment. This Agreement is personal to Executive, and Executive may not assign or delegate any of his rights or obligations under
this Agreement without first obtaining the written consent of the Company. The Company may assign and delegate its rights and obligations under this Agreement, in each case in whole but not in part, without the prior consent of the Executive in the
event that, and only in the event that, (a) the Company shall effect a reorganization, consolidate with, or merge into, any other corporation, partnership, organization or other entity, or transfer all or substantially all of its properties or
assets to any other corporation, partnership, organization or other entity, (b) such corporation, partnership, organization or other entity referred to in the preceding clause “(a)” including without limitation any affiliate thereof
shall by operation of law or expressly in writing assume all obligations of the Company hereunder as fully as if it had been originally made a party to this Agreement. 

12. Notices. All notices required under this Agreement shall be given by personal delivery deemed given on the date of receipt, or by
postage prepaid certified or registered mail, return receipt requested, addressed to the Company or to the Executive as follows, or to such other address as either Party shall notify the other by like notice:

	 If to the Executive:

 ####

 
 With a copy to ####

 If sent by mail, such notice shall be deemed to have been given on the date of delivery set forth on the registered or
certified mail receipt or upon the third (3rd) day after mailing if delivery is refused. 

13. Expenses of Enforcement. In the event that any suit or legal proceeding is brought to enforce any provision of this Agreement, the
prevailing Party in such suit or proceeding shall be entitled to receive all of such Party’s reasonable expenses, including reasonable attorneys’ fees and costs. 

14. Advice of Counsel. The Executive acknowledges that, in executing this Agreement, the Executive has had the opportunity to seek the
advice of independent legal counsel, and has read and understood all of the terms and provisions of this Agreement. This Agreement shall not be construed against any Party by reason of the drafting or preparation hereof. 

15. Section 409A. This Agreement is intended to comply with the requirements of Section 409A of the Internal Revenue Code of 1986,
as amended (“Section 409A”), and the Parties hereby agree to amend this Agreement as and when necessary or desirable to conform to or otherwise properly reflect any guidance issued under Section 409A after
the date hereof without violating Section 409A. In case any one or more provisions of this Agreement fails to comply with the provisions of Section 409A, the remaining provisions of this Agreement shall remain in effect, and this Agreement
shall be administered and applied as if the non-complying provisions were not part of this Agreement. The Parties in that event shall endeavor to agree upon a reasonable substitute for the non-complying provisions, to the extent that a substituted provision would not cause this Agreement to fail to comply with Section 409A, and, upon so agreeing, shall incorporate such substituted provisions into
this Agreement. A termination of the Executive’s employment hereunder shall not be deemed to have occurred for purposes of any provision of this Agreement providing for the payment of any amount or benefit constituting “deferred
compensation” under Section 409A upon or following a termination of employment unless such termination is also a “separation from service” within the meaning of Section 409A and, for purposes of any such

  
 12 

 

 
  

 
provision of this Agreement, references to a “termination,” “termination of employment” or like terms shall mean “separation from service.” In the event that any
payment or benefit made hereunder or under any compensation plan, program or arrangement of the Company would constitute payments or benefits pursuant to a non-qualified deferred compensation plan within the
meaning of Section 409A and, at the time of the Executive’s “separation from service” the Executive is a “specified employee” within the meaning of Section 409A, then any such payments or benefits shall be delayed
until the six-month anniversary of the date of Executive’s “separation from service”. Each payment made under this Agreement shall be designated as a “separate payment” within the
meaning of Section 409A. All reimbursements and in-kind benefits provided under this Agreement shall be made or provided in accordance with the requirements of Section 409A to the extent that such
reimbursements or in-kind benefits are subject to Section 409A. All reimbursements for expenses paid pursuant hereto that constitute taxable income to the Executive shall in no event be paid later than
the end of the calendar year next following the calendar year in which the Executive incurs such expense or pays such related tax. Unless otherwise permitted by Section 409A, the right to reimbursement or
in-kind benefits under this Agreement shall not be subject to liquidation or exchange for another benefit and the amount of expenses eligible for reimbursement, or
in-kind benefits, provided during any taxable year shall not affect the expenses eligible for reimbursement, or in-kind benefits to be provided, respectively, in any
other taxable year. 
  

	 	16.	 Section 280G. 

 

	 	(a)	 Notwithstanding anything contained in this Agreement to the contrary, in the event that any payment or benefit
received or to be received by the 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 part), to the excise tax imposed under Section 4999 of the Code (the “Excise Tax”), then, after taking into account any reduction in the Total Payments provided by reason of Section 280G of the Code
in any other plan, arrangement or agreement, then such remaining Total Payments shall be reduced, to the extent necessary so that no portion of the Total Payments is subject to the Excise Tax but only if (i) the net amount of such Total
Payments, as so reduced (and after subtracting the net amount of federal, state and local income taxes on such reduced Total Payments and after taking into account the phase out of itemized deductions and personal exemptions attributable to such
reduced Total Payments) is greater than or equal to (ii) the net amount of such Total Payments without such reduction (but after subtracting the net amount of federal, state and local income taxes on such Total Payments and the amount of Excise
Tax to which Executive would be subject in respect of such unreduced Total Payments and after taking into account the phase out of itemized deductions and personal exemptions attributable to such unreduced Total Payments). 

 

	 	(b)	 For purposes of determining whether and the extent to which the Total Payments will be subject to the Excise
Tax, (i) no portion of the Total Payments the receipt or enjoyment of which Executive shall have waived at such time and in such manner as not to constitute a “payment” within the meaning of Section 280G(b) of the Code shall be
taken into account; (ii) no portion of the Total Payments shall be 

  
 13 

 

 
  

	 	taken into account which, in the written opinion of an independent, nationally recognized accounting firm (the “Independent Advisors”) selected by the Company, does not constitute a “parachute
payment” within the meaning of Section 280G(b)(2) of the Code (including by reason of Section 280G(b)(4)(A) of the Code) and, in calculating the Excise Tax, no portion of such Total Payments shall be taken into account which, in the
opinion of Independent Advisors, constitutes reasonable compensation for services actually rendered, within the meaning of Section 280G(b)(4)(B) of the Code, in excess of the “base amount” (as defined in Section 280G(b)(3) of the
Code) allocable to such reasonable compensation; and (iii) the value of any non-cash benefit or any deferred payment or benefit included in the Total Payments shall be determined by the Independent
Advisors in accordance with the principles of Sections 280G(d)(3) and (4) of the Code. 

  

	 	17.	 Miscellaneous. 

 

	 	(a)	 This Agreement shall be governed by, and construed exclusively in accordance with, the laws of the State of New
York without giving effect to any choice or conflict of law rules to the contrary. Each Party submits to the nonexclusive jurisdiction of any United States District Court located in New York, New York and of any New York state court sitting in New
York, New York for purposes of all legal proceedings arising out of or relating to this Agreement or the transactions contemplated hereby. Each Party irrevocably waives any objection which it may now or hereafter have to the laying of venue in any
proceeding brought in such a court, and any claim that any such proceeding was brought in an inconvenient forum. 

  

	 	(b)	 Should any provision of this Agreement be held invalid or unenforceable, the remainder of this Agreement shall
not be affected and shall be enforceable to the fullest extent permitted at law or in equity. 

  

	 	(c)	 This Agreement contains the entire agreement between the Parties concerning the subject matter hereof and
supersedes all prior conversations, proposals, negotiations, understandings and agreements, whether written or oral, concerning the subject matter hereof, including, without limitation, the Prior Agreement. 

 

	 	(d)	 This Agreement shall not be amended, altered, changed, modified, supplemented or rescinded in any manner except
by written agreement executed by both Parties expressly referring to this Agreement. 

  

	 	(e)	 No waiver of any provision hereof shall be effective unless made in writing and signed by the waiving Party.
The failure of any Party to require the performance of any term or obligation of this Agreement, or the waiver by any Party of any breach of this Agreement, shall not prevent any subsequent enforcement of such term or obligation or be deemed a
waiver of any subsequent breach. 

  
 14 

 

 
  

	 	(f)	 This Agreement may be executed in any number of counterparts, each of which when so executed and delivered
shall be taken to be an original; but such counterparts shall together constitute one and the same document. 

  

	 	(g)	 The Parties recognize that litigation in federal or state courts or before federal or state administrative
agencies of disputes arising out of the Executive’s employment with the Company or out of this Agreement, or the Executive’s termination of employment or termination of this Agreement, may not be in the best interests of either the
Executive or the Company, and may result in unnecessary costs, delays, complexities, and uncertainty. The Parties agree that any dispute between the Parties arising out of or relating to the negotiation, execution, performance or termination of this
Agreement or the Executive’s employment, including, but not limited to, any claim arising out of this Agreement, claims under Title VII of the Civil Rights Act of 1964, as amended, the Civil Rights Act of 1991, the Age Discrimination in
Employment Act of 1967, the Americans with Disabilities Act of 1990, Section 1981 of the Civil Rights Act of 1966, as amended, the Family Medical Leave Act, the Executive Retirement Income Security Act, and any similar federal, state or local
law, statute, regulation, or any common law doctrine, whether that dispute arises during or after employment, shall be settled by binding arbitration in accordance with the National Rules for the Resolution of Employment Disputes of the American
Arbitration Association; provided, however, that this dispute resolution provision shall not apply to any separate agreements between the Parties that do not themselves specify arbitration as an exclusive remedy. The location
for the arbitration shall be the New York metropolitan area. Any award made by such panel shall be final, binding and conclusive on the Parties for all purposes, and judgment upon the award rendered by the arbitrators may be entered in any court
having jurisdiction thereof. The arbitrators’ fees and expenses and all administrative fees and expenses associated with the filing of the arbitration shall be borne by the Company; provided, however, that at the Executive’s
option, Executive may voluntarily pay up to one-half the costs and fees. The Parties acknowledge and agree that their obligations to arbitrate under this Section survive the termination of this Agreement and
