EX-10.7





 Exhibit 10.7 

EMPLOYMENT AGREEMENT 
 This
Employment Agreement (this “Agreement”) is made between Monte Rosa Therapeutics, Inc., a Delaware corporation (the “Company”), and Markus Warmuth, M.D. (the “Executive”) and is effective as of the
closing of the Company’s first underwritten public offering of its equity securities pursuant to an effective registration statement under the Securities Act of 1933, as amended (the “Effective Date”). Except with respect to
the Restrictive Covenants Agreement and the Equity Documents (each as defined below) and subject to Section 11, this Agreement supersedes in all respects all prior agreements between the Executive and the Company regarding the subject matter
herein, including without limitation (i) the offer letter between the Executive and the Company dated November 15, 2019 (the “Prior Agreement”), and (ii) any other offer letter, employment agreement or severance
agreement. 
 WHEREAS, the Company desires to continue to employ the Executive and the Executive desires to continue to be employed by the
Company on the new terms and conditions contained herein. 
 NOW, THEREFORE, in consideration of the mutual covenants and agreements
herein contained and other good and valuable consideration, the receipt and sufficiency of which is hereby acknowledged, the parties agree as follows: 

1.    Employment. 

(a)    Term. The Company shall employ the Executive and the Executive shall be employed by the Company pursuant to
this Agreement commencing as of the Effective Date and continuing until such employment is terminated in accordance with the provisions hereof (the “Term”). The Executive’s employment with the Company shall continue to be
“at will,” meaning that the Executive’s employment may be terminated by the Company or the Executive at any time and for any reason subject to the terms of this Agreement. 

(b)    Position and Duties. The Executive shall serve as the President and Chief Executive Officer
(“CEO”) of the Company and shall have such powers and duties as may from time to time be prescribed by the Board of Directors (the “Board”). In addition, the Company shall cause the Executive to be nominated for
election to the Board and to be recommended to the stockholders for election to the Board as long as the Executive remains the CEO of the Company, provided that the Executive shall be deemed to have resigned from the Board and from any
related positions upon ceasing to serve as CEO for any reason. The Executive shall devote the Executive’s full working time and efforts to the business and affairs of the Company. Notwithstanding the foregoing, the Executive may serve on other
boards of directors or scientific advisory boards or enter into consulting agreements with the approval of the Board, or engage in religious, charitable or other community activities as long as such services and activities do not interfere with the
Executive’s performance of the Executive’s duties to the Company. 
 (c)    Location. The
Executive’s primary work location will be in the Company’s U.S. office, currently located in Boston, Massachusetts, provided that the Executive may be required to travel regularly for business, including international travel, consistent
with the Company’s business needs. 












 2.    Compensation and Related Matters. 

(a)    Base Salary. The Executive’s initial base salary shall be paid at the rate of $564,600 per year. The
Executive’s base salary shall be subject to periodic review by the Board or the Compensation Committee of the Board (the “Compensation Committee”). The base salary in effect at any given time is referred to herein as
“Base Salary.” The Base Salary shall be payable in a manner that is consistent with the Company’s usual payroll practices for its executive officers. 

(b)    Incentive Compensation. The Executive shall be eligible to receive cash incentive compensation as determined
by the Board or the Compensation Committee from time to time. The Executive’s initial target annual incentive compensation shall be 50 percent of the Executive’s Base Salary. The target annual incentive compensation in effect at any
given time is referred to herein as the “Target Bonus.” The actual amount of the Executive’s annual incentive compensation, if any, shall be determined in the sole discretion of the Board or the Compensation Committee. Any
annual bonus will be paid no later than March 15th of the calendar year following the calendar year to which such bonus relates. Except as otherwise provided herein or as may be provided by the
Board or the Compensation Committee, the Executive must be employed by the Company on the date such incentive compensation is paid in order to earn or receive any annual incentive compensation. 

(c)    Expenses. The Executive shall be entitled to receive prompt reimbursement for all reasonable expenses
incurred by the Executive during the Term in performing services hereunder, in accordance with the policies and procedures then in effect and established by the Company for its executive officers. 

(d)    Other Benefits. The Executive shall be eligible to participate in or receive benefits under the
Company’s employee benefit plans in effect from time to time, subject to the terms of such plans. 
 (e)    Paid
Time Off. The Executive shall be entitled to take paid time off in accordance with the Company’s applicable paid time off policy for executives, as may be in effect from time to time. 

(f)    Equity. The equity awards held by the Executive shall continue to be governed by the terms and conditions of
the Company’s applicable equity incentive plan(s) and the applicable award agreement(s) governing the terms of such equity awards (collectively, the “Equity Documents”); provided, however, and notwithstanding anything to
the contrary in the Equity Documents, in the event of a termination by the Company without Cause or by the Executive for Good Reason, in either event within the Change in Control Period (as such terms are defined below), all stock options and other
stock-based awards held by the Executive shall immediately accelerate and become fully vested and exercisable or nonforfeitable as of the Date of Termination (as defined below) or, if later, the Change in Control. 

3.    Termination. The Executive’s employment hereunder may be terminated without any breach of this Agreement
under the following circumstances: 

  
 2 













 (a)    Death. The Executive’s employment hereunder shall
terminate upon death. 
 (b)    Disability. The Company may terminate the Executive’s employment if the
Executive is disabled and unable to perform or expected to be unable to perform the essential functions of the Executive’s then existing position or positions under this Agreement with or without reasonable accommodation for a period of 180
days (which need not be consecutive) in any 12-month period. If any question shall arise as to whether during any period the Executive is disabled so as to be unable to perform the essential functions of the
Executive’s then existing position or positions with or without reasonable accommodation, the Executive may, and at the request of the Company shall, submit to the Company a certification in reasonable detail by a physician selected by the
Company to whom the Executive or the Executive’s guardian has no reasonable objection as to whether the Executive is so disabled or how long such disability is expected to continue, and such certification shall for the purposes of this
Agreement be conclusive of the issue. The Executive shall cooperate with any reasonable request of the physician in connection with such certification. If such question shall arise and the Executive shall fail to submit such certification, the
Company’s determination of such issue shall be binding on the Executive. Nothing in this Section 3(b) shall be construed to waive the Executive’s rights, if any, under existing law including, without limitation, the Family and Medical
Leave Act of 1993, 29 U.S.C. §2601 et seq. and the Americans with Disabilities Act, 42 U.S.C. §12101 et seq. 

(c)    Termination by the Company for Cause. The Company may terminate the Executive’s employment hereunder
for Cause. For purposes of this Agreement, “Cause” shall mean, as determined by the Board in good faith, any of the following: 

(i)    the Executive’s willful misconduct in connection with the performance of the Executive’s duties,
including, without limitation, misappropriation of funds or property of the Company other than the occasional, customary and de minimis use of Company property for personal purposes; 

(ii)    the Executive’s commission of acts satisfying the elements of (A) any felony or (B) a misdemeanor
involving moral turpitude, deceit, dishonesty, fraud or conduct by the Executive that would reasonably be expected to result in material injury or reputational harm to the Company if the Executive was retained in the Executive’s position; 

(iii)    the Executive’s continued non-performance of the Executive’s
duties that has continued for more than 15 days following written notice of such non-performance; 

(iv)    a material breach by the Executive of the Restrictive Covenants Agreement or any other confidentiality,
assignment, noncompetition and/or nonsolicitation obligations; 
 (v)    a material violation by the Executive of the
Company’s lawful written employment policies; 

  
 3 













 (vi)    the Executive’s diversion of any business or business
opportunity of the Company for the benefit of any party other than the Company without the consent of the Company; or 

(vii)    the Executive’s failure to cooperate with an internal investigation or an investigation by regulatory or
law enforcement authorities, after being instructed by the Company to cooperate, or the willful destruction or failure to preserve documents or other materials known to be relevant to such investigation or the inducement of others to fail to
cooperate or to produce documents or other materials in connection with such investigation. 
 (d)    Termination by
the Company without Cause. The Company may terminate the Executive’s employment hereunder at any time without Cause. Any termination by the Company of the Executive’s employment under this Agreement which does not constitute a
termination for Cause under Section 3(c) and does not result from the death or disability of the Executive under Section 3(a) or (b) shall be deemed a termination without Cause. 

(e)    Termination by the Executive. The Executive may terminate employment hereunder at any time for any reason,
including but not limited to, Good Reason. For purposes of this Agreement, “Good Reason” shall mean that the Executive has completed all steps of the Good Reason Process (hereinafter defined) following the occurrence of any of the
following events without the Executive’s consent (each, a “Good Reason Condition”): 

(i)    a material diminution in the Executive’s responsibilities, authority or duties; 

(ii)    a material diminution in the Executive’s Base Salary except for
across-the-board salary reductions based on the Company’s financial performance similarly affecting all or substantially all senior management employees of the
Company; 
 (iii)    a material change in the geographic location of the principal office of the Company
to which the Executive is assigned, such that there is an increase of at least fifty (50) miles of driving distance to such location from the Executive’s principal residence as of such change; 

(iv)    the Executive’s removal from the role of Chief Executive Officer or President without Cause;

 (v)    the Executive no longer reporting directly and exclusively to the Board; or 

(vi)    a material breach of this Agreement by the Company. 

The “Good Reason Process” consists of the following steps: 

(i)    the Executive reasonably determines in good faith that a Good Reason Condition has occurred; 

  
 4 













 (ii)    the Executive notifies the Company in writing of
the first occurrence of the Good Reason Condition within 60 days of the first occurrence of such condition; 

(iii)    the Executive cooperates in good faith with the Company’s efforts, for a period of not less
than 30 days following such notice (the “Cure Period”), to remedy the Good Reason Condition; 

(iv)    notwithstanding such efforts, the Good Reason Condition continues to exist at the end of the Cure
Period; and 
 (v)    the Executive terminates employment within 60 days after the end of the Cure
Period. 
 If the Company cures the Good Reason Condition during the Cure Period, Good Reason shall be deemed not to have occurred. 

4.    Matters related to Termination. 

(a)    Notice of Termination. Except for termination as specified in Section 3(a), any termination of the
Executive’s employment by the Company or any such termination by the Executive shall be communicated by written Notice of Termination to the other party hereto. For purposes of this Agreement, a “Notice of Termination” shall
mean a notice which shall indicate the specific termination provision in this Agreement relied upon. 
 (b)    Date
of Termination. “Date of Termination” shall mean: (i) if the Executive’s employment is terminated by death, the date of death; (ii) if the Executive’s employment is terminated on account of disability under
Section 3(b) or by the Company for Cause under Section 3(c), the date on which Notice of Termination is given; (iii) if the Executive’s employment is terminated by the Company without Cause under Section 3(d), the date on
which a Notice of Termination is given or the date otherwise specified by the Company in the Notice of Termination; (iv) if the Executive’s employment is terminated by the Executive under Section 3(e) other than for Good Reason, 30
days after the date on which a Notice of Termination is given, and (v) if the Executive’s employment is terminated by the Executive under Section 3(e) for Good Reason, the date on which a Notice of Termination is given after the end
of the Cure Period. Notwithstanding the foregoing, in the event that the Executive gives a Notice of Termination to the Company, the Company may unilaterally accelerate the Date of Termination and such acceleration shall not result in a termination
by the Company for purposes of this Agreement. 
 (c)    Accrued Obligations. If the Executive’s employment
with the Company is terminated for any reason, the Company shall pay or provide to the Executive (or to the Executive’s authorized representative or estate) (i) any Base Salary earned through the Date of Termination;
(ii) unpaid expense reimbursements (subject to, and in accordance with, Section 2(c) of this Agreement); and (iii) any vested benefits the Executive may have under any employee benefit plan of the Company through the Date of
Termination, which vested benefits shall be paid and/or provided in accordance with the terms of such employee benefit plans (collectively, the “Accrued Obligations”). 

  
 5 













 (d)    Resignation of All Other Positions. To the extent
applicable, the Executive shall be deemed to have resigned from all officer and board member positions that the Executive holds with the Company or any of its respective subsidiaries and affiliates upon the termination of the Executive’s
employment for any reason. The Executive shall execute any documents in reasonable form as may be requested to confirm or effectuate any such resignations. 

5.    Severance Pay and Benefits Upon Termination by the Company without Cause or by the Executive for Good Reason
Outside the Change in Control Period. If the Executive’s employment is terminated by the Company without Cause as provided in Section 3(d), or the Executive terminates employment for Good Reason as provided in Section 3(e), in
each case outside of the Change in Control Period (as defined below), then, in addition to the Accrued Obligations, and subject to (i) the Executive signing a separation agreement and release in a form and manner satisfactory to the
Company, which shall include, without limitation, a general release of claims against the Company and all related persons and entities that shall not release the Executive’s rights under this Agreement, a reaffirmation of all of the
Executive’s Continuing Obligations (as defined below), and, in the Company’s sole discretion, a one-year post-employment noncompetition agreement, and shall provide that if the Executive breaches any
of the Continuing Obligations, all payments of the Severance Amount shall immediately cease (the “Separation Agreement”), and (ii) the Separation Agreement becoming irrevocable, all within 60 days after the Date of Termination
(or such shorter period as set forth in the Separation Agreement), which shall include a seven (7) business day revocation period: 

(a)    the Company shall pay the Executive an amount equal to the sum of (A) 12 months of the Executive’s Base Salary
plus (B) the Executive’s Target Bonus for the then-current year (the “Severance Amount”); provided that in the event the Executive is entitled to any payments pursuant to the Restrictive Covenants Agreement,
the Severance Amount received in any calendar year will be reduced by the amount the Executive is paid in the same such calendar year pursuant to the Restrictive Covenants Agreement (the “Restrictive Covenants Agreement Setoff”);
and 
 (b)    subject to the Executive’s copayment of premium amounts at the applicable active employees’ rate
and the Executive’s proper election to receive benefits under the Consolidated Omnibus Budget Reconciliation Act of 1985, as amended (“COBRA”), the Company shall pay to the group health plan provider or the COBRA provider a
monthly payment equal to the monthly employer contribution that the Company would have made to provide health insurance to the Executive if the Executive had remained employed by the Company until the earliest of (A) the 12 month anniversary of
the Date of Termination; (B) the date that the Executive becomes eligible for group medical plan benefits under any other employer’s group medical plan; or (C) the cessation of the Executive’s health continuation rights under
COBRA; provided, however, that if the Company determines that it cannot pay such amounts to the group health plan provider or the COBRA provider (if applicable) without potentially violating applicable law (including, without limitation,
Section 2716 of the Public Health Service Act), then the Company shall convert such payments to payroll payments directly to the Executive for the time period specified above. Such payments to the Executive shall be subject to tax-related deductions and withholdings and paid on the Company’s regular payroll dates; and 

  
 6 













 (c)    notwithstanding anything to the contrary in any of the Equity
Documents: (i) the portion of all time-based stock options and other stock-based awards subject solely to time-based vesting held by the Executive as of the Effective Date (the “Time-Based Equity Awards”) scheduled to vest in
the 12 month period following the Date of Termination shall immediately accelerate and become fully vested and exercisable or nonforfeitable as of the later of (A) the Date of Termination or (B) the effective date of the Separation
Agreement (the “Accelerated Vesting Date”); and (ii) with respect to vested stock options that were granted prior to the Effective Date, the Executive shall have until the earlier of the expiration date of the stock option or
the date that is one (1) year from the Date of Termination to exercise all vested stock options, unless the Equity Documents pursuant to which such stock options are granted require or authorize earlier termination in connection with a
liquidation or sale of the Company; provided that in order to effectuate the accelerated vesting contemplated by this subsection, the unvested portion of the Executive’s Time-Based Equity Awards that are subject to acceleration pursuant
to this subsection that would otherwise be forfeited on the Date of Termination will be delayed until the earlier of (A) the effective date of the Separation Agreement (at which time acceleration will occur), or (B) the date that the
Separation Agreement can no longer become fully effective (at which time the unvested portion of the Executive’s Time-Based Equity Awards subject to acceleration pursuant to this subsection will be forfeited). Notwithstanding the foregoing, no
additional vesting of the Time-Based Equity Awards shall occur during the period between the Date of Termination and the Accelerated Vesting Date. With respect to any performance-based vesting equity award, such award shall continue to be governed
in all respects by the terms of the applicable equity award documents. 
 The amounts payable under Section 5, to the extent taxable, shall be paid out
in substantially equal installments in accordance with the Company’s payroll practice over 12 months commencing within 60 days after the Date of Termination; provided, however, that if the
60-day period begins in one calendar year and ends in a second calendar year, such payments, to the extent they qualify as “non-qualified deferred
compensation” within the meaning of Section 409A of the Internal Revenue Code of 1986, as amended (the “Code”), shall begin to be paid in the second calendar year by the last day of such
60-day period; provided, further, that the initial payment shall include a catch-up payment to cover amounts retroactive to the day immediately following the Date
of Termination. Each payment pursuant to this Agreement is intended to constitute a separate payment for purposes of Treasury Regulation Section 1.409A-2(b)(2). 

The Executive shall not be required to mitigate the amount of any payments provided for under this Section 5 or Section 6 of this Agreement by
seeking other employment, and no payment shall be offset or reduced by the amount of any compensation or benefits provided to the Executive in any subsequent employment. 

6.    Severance Pay and Benefits Upon Termination by the Company without Cause or by the Executive for Good Reason
within the Change in Control Period. The provisions of this Section 6 shall apply in lieu of, and expressly supersede, the provisions of Section 5 if (i) the Executive’s employment is terminated either (a) by the Company
without Cause as provided in Section 3(d), or (b) by the Executive for Good Reason as provided in Section 3(e), and (ii) the Date of Termination is within three (3) months prior to, on or within 12 months after the
occurrence of the first event constituting a Change in Control (such period, the “Change in Control Period”). These provisions shall terminate and be of no further force or effect after the


  
 7 













 
Change in Control Period. For the avoidance of doubt, (i) in no event will the Executive be entitled to severance benefits under both Section 5 and Section 6 of this Agreement, and
(ii) if the Company has commenced providing severance pay and benefits to the Executive under Section 5 prior to the date that the Executive becomes eligible to receive severance pay and benefits under this Section 6, the severance
pay and benefits previously provided to the Executive under Section 5 shall reduce the severance pay and benefits to be provided under this Section 6. 

(a)    If the Executive’s employment is terminated by the Company without Cause as provided in Section 3(d) or
the Executive terminates employment for Good Reason as provided in Section 3(e) and in each case the Date of Termination occurs during the Change in Control Period, then, in addition to the Accrued Obligations, and subject to the signing of a
general release of claims against the Company and all related persons and entities that shall not release the Executive’s rights under this Agreement (the “Release”) by the Executive and the Release becoming fully effective,
all within the time frame set forth in the Release but in no event more than 60 days after the Date of Termination: 

(i)    the Company shall pay the Executive a lump sum in cash in an amount equal to the sum of (A)
18 months of the Executive’s then-current Base Salary (or the Executive’s Base Salary in effect immediately prior to the Change in Control, if higher) plus (B) 1.5 times the Executive’s Target Bonus for the then-current year (or the
Executive’s Target Bonus in effect immediately prior to the Change in Control, if higher) (the “Change in Control Payment”); provided that the Change in Control Payment shall be reduced by the amount of the Restrictive
Covenants Agreement Setoff, if applicable; and 
 (ii)    subject to the Executive’s copayment of
premium amounts at the applicable active employees’ rate and the Executive’s proper election to receive benefits under COBRA, the Company shall pay to the group health plan provider or the COBRA provider a monthly payment equal to the
monthly employer contribution that the Company would have made to provide health insurance to the Executive if the Executive had remained employed by the Company until the earliest of (A) the 18 month anniversary of the Date of Termination;
(B) the date that the Executive becomes eligible for group medical plan benefits under any other employer’s group medical plan; or (C) the cessation of the Executive’s health continuation rights under COBRA; provided,
however, that if the Company determines that it cannot pay such amounts to the group health plan provider or the COBRA provider (if applicable) without potentially violating applicable law (including, without limitation, Section 2716 of the
Public Health Service Act), then the Company shall convert such payments to payroll payments directly to the Executive for the time period specified above. Such payments to the Executive shall be subject to
tax-related deductions and withholdings and paid on the Company’s regular payroll dates; and 

(iii)    with respect to vested stock options that were granted prior to the Effective Date, the Executive
shall have until the earlier of the expiration date of the stock option or the date that is one (1) year from the Date of Termination to exercise all vested stock options, unless the Equity Documents pursuant to which such stock options are
granted require or authorize earlier termination in connection with a liquidation or sale of the Company. 

  
 8 













 The amounts payable under this Section 6(a), to the extent taxable, shall be paid or commence to be
paid within 60 days after the Date of Termination or, if later, the Change in Control; provided, however, that if the 60-day period begins in one calendar year and ends in a second calendar year, such
payments to the extent they qualify as “non-qualified deferred compensation” within the meaning of Section 409A of the Code, shall be paid or commence to be paid in the second calendar year by
the last day of such 60-day period. 
 (b)    Additional Limitation. 

(i)    Anything in this Agreement to the contrary notwithstanding, in the event that the amount of any
compensation, payment or distribution by the Company to or for the benefit of the Executive, whether paid or payable or distributed or distributable pursuant to the terms of this Agreement or otherwise, calculated in a manner consistent with
Section 280G of the Code, and the applicable regulations thereunder (the “Aggregate Payments”), would be subject to the excise tax imposed by Section 4999 of the Code, then the Aggregate Payments shall be reduced (but not
below zero) so that the sum of all of the Aggregate Payments shall be $1.00 less than the amount at which the Executive becomes subject to the excise tax imposed by Section 4999 of the Code; provided that such reduction shall only occur
if it would result in the Executive receiving a higher After Tax Amount (as defined below) than the Executive would receive if the Aggregate Payments were not subject to such reduction. In such event, the Aggregate Payments shall be reduced in the
following order, in each case, in reverse chronological order beginning with the Aggregate Payments that are to be paid the furthest in time from consummation of the transaction that is subject to Section 280G of the Code: (1) cash
payments not subject to Section 409A of the Code; (2) cash payments subject to Section 409A of the Code; (3) equity-based payments and acceleration; and (4) non-cash forms of benefits;
provided that in the case of all the foregoing Aggregate Payments all amounts or payments that are not subject to calculation under Treas. Reg. §1.280G-1,
Q&A-24(b) or (c) shall be reduced before any amounts that are subject to calculation under Treas. Reg. §1.280G-1,
Q&A-24(b) or (c). 
 (ii)    For purposes of this
Section 6(b), the “After Tax Amount” means the amount of the Aggregate Payments less all federal, state, and local income, excise and employment taxes imposed on the Executive as a result of the Executive’s receipt of the
Aggregate Payments. For purposes of determining the After Tax Amount, the Executive shall be deemed to pay federal income taxes at the highest marginal rate of federal income taxation applicable to individuals for the calendar year in which the
determination is to be made, and state and local income taxes at the highest marginal rates of individual taxation in each applicable state and locality, net of the maximum reduction in federal income taxes which could be obtained from deduction of
such state and local taxes. 
 (iii)    The determination as to whether a reduction in the Aggregate
Payments shall be made pursuant to Section 6(b)(i) shall be made by a nationally recognized accounting firm selected by the Company (the “Accounting Firm”), which 

  
 9 













 
shall provide detailed supporting calculations both to the Company and the Executive within 15 business days of the Date of Termination, if applicable, or at such earlier time as is reasonably
requested by the Company or the Executive. Any determination by the Accounting Firm shall be binding upon the Company and the Executive. 

(c)    Definitions. For purposes of this Agreement, “Change in Control” shall mean a “Sale
Event” as defined in the Company’s 2021 Stock Option and Incentive Plan (as the same may be amended from time to time). 

7.    Section 409A. 

(a)    Anything in this Agreement to the contrary notwithstanding, if at the time of the Executive’s separation from
service within the meaning of Section 409A of the Code, the Company determines that the Executive is a “specified employee” within the meaning of Section 409A(a)(2)(B)(i) of the Code, then to the extent any payment or benefit
that the Executive becomes entitled to under this Agreement or otherwise on account of the Executive’s separation from service would be considered deferred compensation otherwise subject to the 20 percent additional tax imposed pursuant to
Section 409A(a) of the Code as a result of the application of Section 409A(a)(2)(B)(i) of the Code, such payment shall not be payable and such benefit shall not be provided until the date that is the earlier of (A) six months and one
day after the Executive’s separation from service, or (B) the Executive’s death. If any such delayed cash payment is otherwise payable on an installment basis, the first payment shall include a
catch-up payment covering amounts that would otherwise have been paid during the six-month period but for the application of this provision, and the balance of the
installments shall be payable in accordance with their original schedule. 
 (b)    All
in-kind benefits provided and expenses eligible for reimbursement under this Agreement shall be provided by the Company or incurred by the Executive during the time periods set forth in this Agreement. All
reimbursements shall be paid as soon as administratively practicable, but in no event shall any reimbursement be paid after the last day of the taxable year following the taxable year in which the expense was incurred. The amount of in-kind benefits provided or reimbursable expenses incurred in one taxable year shall not affect the in-kind benefits to be provided or the expenses eligible for reimbursement
in any other taxable year (except for any lifetime or other aggregate limitation applicable to medical expenses). Such right to reimbursement or in-kind benefits is not subject to liquidation or exchange for
another benefit. 
 (c)    To the extent that any payment or benefit described in this Agreement constitutes “non-qualified deferred compensation” under Section 409A of the Code, and to the extent that such payment or benefit is payable upon the Executive’s termination of employment, then such payments
or benefits shall be payable only upon the Executive’s “separation from service.” The determination of whether and when a separation from service has occurred shall be made in accordance with the presumptions set forth in Treasury
Regulation Section 1.409A-1(h). 
 (d)    The parties intend that this
Agreement will be administered in accordance with Section 409A of the Code. To the extent that any provision of this Agreement is ambiguous 

  
 10 













 
as to its compliance with Section 409A of the Code, the provision shall be read in such a manner so that all payments hereunder comply with Section 409A of the Code. Each payment
pursuant to this Agreement or the Restrictive Covenants Agreement is intended to constitute a separate payment for purposes of Treasury Regulation Section 1.409A-2(b)(2). The parties agree that this
Agreement may be amended, as reasonably requested by either party, and as may be necessary to fully comply with Section 409A of the Code and all related rules and regulations in order to preserve the payments and benefits provided hereunder
without additional cost to either party. 
 (e)    The Company makes no representation or warranty and shall have no
liability to the Executive or any other person if any provisions of this Agreement are determined to constitute deferred compensation subject to Section 409A of the Code but do not satisfy an exemption from, or the conditions of, such Section.

 8.    Continuing Obligations.  

(a)    Restrictive Covenants Agreement. The terms of the Employee Confidentiality, Assignment, Nonsolicitation and
Noncompetition Agreement, dated February 14, 2020 (the “Restrictive Covenants Agreement”), between the Company and the Executive, attached hereto as Exhibit A, continue to be in full force and effect. For purposes of this
Agreement, the obligations in this Section 8 and those that arise in the Restrictive Covenants Agreement and any other agreement relating to confidentiality, assignment of inventions, or other restrictive covenants shall collectively be
referred to as the “Continuing Obligations.” 
 (b)    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, other than confidentiality
restrictions (if any), 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 employment with the Company and the performance of the
Executive’s proposed duties for the Company 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, 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 any copies or other tangible embodiments of
non-public information belonging to or obtained from any such previous employment or other party. 

(c)    Litigation and Regulatory Cooperation. During and after the Executive’s employment, the Executive shall
cooperate fully with the Company in (i) the defense or prosecution of any claims or actions now in existence or which may be brought in the future against or on behalf of the Company which relate to events or occurrences that transpired while
the Executive was employed by the Company, and (ii) the investigation, whether internal or external, of any matters about which the Company believes the Executive may have knowledge or information. The Executive’s full cooperation in
connection with such claims, actions or investigations shall include, but not be limited to, being available to meet with counsel to answer questions or to prepare for discovery or trial and to act as a witness on behalf of the Company at mutually
convenient times. During and after the Executive’s employment, the Executive also shall cooperate fully with the Company 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
shall reimburse the Executive for any reasonable out-of-pocket expenses incurred in connection with the Executive’s performance of obligations pursuant to this
Section 8(c). 
 (d)    Relief. The Executive agrees that it would be difficult to measure any damages
caused to the Company which might result from any breach by the Executive of the Continuing Obligations, and that in any event money damages would be an inadequate remedy for any such breach. Accordingly, the Executive agrees that if the
Executive breaches, or proposes to breach, any portion of the Continuing Obligations, the Company shall be entitled, in addition to all other remedies that it may have, to an injunction or other appropriate equitable relief to restrain any such
breach without showing or proving any actual damage to the Company. 
 9.    Consent to Jurisdiction. The parties
hereby consent to the jurisdiction of the state and federal courts of the Commonwealth of Massachusetts. Accordingly, with respect to any such court action, the Executive (a) submits to the exclusive 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. 

10.    Waiver of Jury Trial. Each of the Executive and the Company irrevocably and unconditionally WAIVES ALL RIGHT
TO TRIAL BY JURY IN ANY PROCEEDING (WHETHER BASED ON CONTRACT, TORT OR OTHERWISE) ARISING OUT OF OR RELATING TO THIS AGREEMENT OR THE EXECUTIVE’S EMPLOYMENT BY THE COMPANY OR ANY AFFILIATE OF THE COMPANY, INCLUDING WITHOUT LIMITATION THE
EXECUTIVE’S OR THE COMPANY’S PERFORMANCE UNDER, OR THE ENFORCEMENT OF, THIS AGREEMENT. 

11.    Integration. This Agreement constitutes the entire agreement between the parties with respect to the subject
matter hereof and supersedes all prior agreements between the parties concerning such subject matter, including the Prior Agreement, provided that the Restrictive Covenants Agreement and the Equity Documents remain in full force and effect.

 12.    Withholding; Tax Effect. All payments made by the Company to the Executive under this Agreement shall
be net of any tax or other amounts required to be withheld by the Company under applicable law. Nothing in this Agreement shall be construed to require the Company to make any payments to compensate the Executive for any adverse tax effect
associated with any payments or benefits or for any deduction or withholding from any payment or benefit. 

13.    Assignment; Successors and Assigns. Neither the Executive nor the Company may make any assignment of this
Agreement or any interest in it, by operation of law or otherwise, without the prior written consent of the other; provided, however, that the Company may assign its rights and obligations under this Agreement (including the Restrictive
Covenants Agreement) without the Executive’s consent to any affiliate or to any person or entity with whom the Company shall hereafter effect a reorganization or consolidation, into which the Company merges or to whom it transfers all or
substantially all of its properties or assets; 

  
 12 













 
provided, further that if the Executive remains employed or becomes employed by the Company, the purchaser or any of their affiliates in connection with any such transaction, then the
Executive shall not be entitled to any payments, benefits or vesting pursuant to Section 2(f), Section 5 or Section 6 of this Agreement solely as a result of such transaction. This Agreement shall inure to the benefit of and be
binding upon the Executive and the Company, and each of the Executive’s and the Company’s respective successors, executors, administrators, heirs and permitted assigns. In the event of the Executive’s death after the Executive’s
termination of employment but prior to the completion by the Company of all payments due to the Executive under this Agreement, the Company shall continue such payments to the Executive’s beneficiary designated in writing to the Company prior
to the Executive’s death (or to the Executive’s estate, if the Executive fails to make such designation). 

14.    Enforceability. If any portion or provision of this Agreement (including, without limitation, any portion or
provision of any section of this Agreement) shall to any extent be declared illegal or unenforceable by a court of competent jurisdiction, then the remainder of this Agreement, or the application of such portion or provision in circumstances other
than those as to which it is so declared illegal or unenforceable, shall not be affected thereby, and each portion and provision of this Agreement shall be valid and enforceable to the fullest extent permitted by law. 

15.    Survival. For the avoidance of doubt, this Agreement shall survive the termination of the Executive’s
employment to the extent necessary to effectuate the terms contained herein. 
 16.    Waiver. 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. 

17.    Notices. Any notices, requests, demands and other communications provided for by this Agreement shall be
sufficient if in writing and delivered in person or sent by a nationally recognized overnight courier service or by registered or certified mail, postage prepaid, return receipt requested, to the Executive at the last address the Executive has filed
in writing with the Company or, in the case of the Company, at its main offices, attention of the Board. 

18.    Amendment. This Agreement may be amended or modified only by a written instrument signed by the Executive
and by a duly authorized representative of the Company. 
 19.    Effect on Other Plans and Agreements. An
election by the Executive to resign for Good Reason under the provisions of this Agreement shall not be deemed a voluntary termination of employment by the Executive for the purpose of interpreting the provisions of any of the Company’s benefit
plans, programs or policies. Nothing in this Agreement shall be construed to limit the rights of the Executive under the Company’s benefit plans, programs or policies except as otherwise provided in Section 8 hereof, and except that the
Executive shall have no rights to any severance benefits under any Company severance pay plan, offer letter or otherwise. Except for the Restrictive Covenants Agreement, in the event that the Executive is


  
 13 













 
party to an agreement with the Company providing for payments or benefits under such plan or agreement and under this Agreement, the terms of this Agreement shall govern and the Executive may
receive payment under this Agreement only and not both. Further, Section 5 and Section 6 of this Agreement are mutually exclusive and in no event shall the Executive be entitled to payments or benefits pursuant to both Section 5 and
Section 6 of this Agreement. 
 20.    Governing Law. This is a Massachusetts contract and shall be
construed under and be governed in all respects by the laws of the Commonwealth of Massachusetts without giving effect to the conflict of laws principles thereof. With respect to any disputes concerning federal law, such disputes shall be determined
in accordance with the law as it would be interpreted and applied by the United States Court of Appeals for the First Circuit. 

21.    Counterparts. 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.
