7.    Proprietary Rights. 

7.1     Definitions. For the purposes of this Article 7, the terms set forth below shall have the following
meanings: 

  
 3 

 7.1.1 Concept and Ideas. Those concepts and ideas disclosed by the Company to
Employee or which are first developed or conceived by Employee during the Employment Term and which relate to the Company’s present, past or prospective activities, services and products, all of which shall remain the sole and exclusive
property of the Company (hereinafter, collectively referred as “Concepts and Ideas”). Further, the Employee shall have no publication rights hereunder and all of the same shall belong exclusively to the Company. Employee acknowledges and
agrees that all works and tasks performed by Employee for or on behalf of the Company, or in connection therewith during the Employment Terms (the “Works”) are owned by the Company. Employee acknowledges and agrees that, to the fullest
extent allowed by law, all of the Works are “works made for hire,” as that phrase is defined in the Copyright Revision Act of 1976 (17 U.S.C. § IOI) (the “Act”) in that either: (i) such Works are and will be prepared
within the scope of this Agreement or (ii) such Works have been and will be specifically ordered or commissioned for use as set forth in the Act. The Company shall therefore be deemed to be the sole author and owner of any and all right, title,
and interest therein, including, without limitation, all intellectual property rights. 
 7.1.2. Confidential Information.
Confidential Information means that secret or proprietary information of whatever kind or nature disclosed to Employee by or on behalf of the Company during the Employment Term (whether or not invented, discovered or developed by Employee) or first
developed by Employee hereunder or otherwise during the Employment Term, or any other information derived from the Confidential Information. Such secret or proprietary information shall include (unless such information is generally available to the
public or known in the industry through no action of Employee) information relating to the design, manufacture, application, trade secrets, know how, research and development relating to the Company’s products, materials, operating and other
cost data, price lists and data relating to the Company’s products. Such secret or proprietary information shall specifically include, without limitation, all such secret or proprietary information contained in the Company’s manuals,
memoranda, plans, drawings and designs, specifications, supply sources, customer lists and records legended or otherwise identified by the Company or the Board as Confidential Information. The Employee’s obligations with respect to Confidential
Information will cease when the Confidential Information: (i) becomes part of the public domain through no wrongful act of the Employee, or (ii) is approved for release by prior written authorization of the Company. However, Confidential
Information shall be considered Confidential Information even if a portion or specific sections of the Confidential Information are known or generally available to the general public; and the Confidential Information shall not lose its character and
status as Confidential Information unless and until all of the Confidential Information is in the public domain. 

7.2.    Non-Disclosure to Third Parties. Except as required by
Employee’s duties, Employee shall not, at any time, now or in the future, directly or indirectly, use, publish, disseminate, reproduce or otherwise disclose any Confidential Information, Concepts and Ideas relating to the present, past or
prospective business of the Company to any third party. Further, and recognizing the highly competitive nature of the Company’s business and the need to protect its intellectual property, all publication rights shall belong solely to the
Company. 
 7.3.    Documents, etc. All documents, procedural manuals, guides, specifications, plans, drawings,
designs and similar materials, lists of present, past or prospective customers, customer proposals, invitations to submit proposals, price lists and data relating to the pricing of the Company’s products and services, records, notebooks and
similar repositories of or containing Confidential Information (including all copies thereof) that come into Employee’s possession or control by reason of Employee’s relationship with the Company, whether prepared by Employee or others:
(a) are and shall remain the property of the Company, (b) will not be used by Employee in any way adverse to the Company, (c) will not be removed from the Company’s premises (except as Employee’s duties require) and (d) at
the termination (for whatever reason) of Employee’s relationship with the Company, will be left with, or forthwith returned by Employee to, the Company. 

  
 4 

 7.4.    Patents, etc. Any interest in patents, patent
applications, inventions, technological innovations, improvements, enhancements, copyrights, copyrightable works, developments, discoveries, designs, processes, formulas, know-how, data and analysis, whether
patentable or not (collectively, the “Inventions”), which Employee as a result of rendering the Services to the Company under this Agreement may conceive or develop shall belong exclusively to the Company. 

7.5.    Assignment. The Employee hereby irrevocably assigns and, to the extent any such assignment cannot be made
at present, hereby agrees to irrevocably and automatically assign to the Company, without further compensation or consideration of his rights, title and interest in and to all Concepts, Ideas, Works, and Inventions and any and all related patents,
patent applications, copyrights, copyright applications, licenses, trademarks, trade names and other proprietary or intellectual property rights in the United States and throughout the world. The Employee agrees that he will promptly, without any
additional costs, expense or consideration, execute when presented, whether during the Employment Term or at any time thereafter, all documents, agreements, applications and instruments and perform all lawful acts which the Company considers
necessary or advisable to secure its rights hereunder and to carry out the intent of this Agreement. 

8.    Specific Performance. Employee agrees that any violation by him of Sections 6 or 7 of this Agreement would be
highly injurious to the Company and would cause irreparable harm to the Company. By reason of the foregoing, Employee consents and agrees that if he violates or threatens to violate any provision(s) of Sections 6 or 7 of this Agreement, the Company
shall be entitled, in addition to any other rights and remedies that it may have, to apply to any court of competent jurisdiction for specific performance and/or injunctive or other equitable relief (without the requirement of posting of a bond or
other security) in order to enforce, or prevent any continuing or potential violation of, the provisions of such Section(s). The Employee also recognizes that the territorial, time and scope limitations set forth in Sections 6 and 7, as applicable,
are reasonable and are properly required and necessary for the protection of the Company and in the event that any such territorial, time or scope limitation is deemed to be unreasonable by a court of competent jurisdiction, the Company and the
Employee agree, and Employee submits, to the reduction of any or all of said territorial, time or scope limitations to such an area, period or scope as said court shall deem reasonable under the circumstances. If such partial enforcement is not
possible, the provision shall be deemed severed, and the remaining provisions of this Agreement shall remain in full force and effect. Employee acknowledges that Sections 6 and 7 of this Agreement shall survive termination or expiration of the
Employee’s employment.

 9.    Termination. Notwithstanding the notice provision of
Article 1 hereof, Employee’s employment with the Company: (i) shall terminate upon the Employee’s resignation, death or disability, (ii) may be terminated without prior notice by the Board for Just Cause (as defined herein) and
(iii) may be terminated without cause by either party upon twenty (20) days prior notice to the other party as set forth in Article 1 hereof. As used in this Agreement, “Just Cause” means any of the following, as
determined by the Board, in its reasonable judgment: (1) Employee’s continuous failure or continuous refusal to perform the duties and responsibilities as are requested of him by the Company; (2) Employee’s gross negligence or
willful misconduct in the performance of Employee’s duties or (3) the commission by Employee of any act of embezzlement against Company or the commission of any felony or act involving moral turpitude. 

Except as hereinafter provided, effective as of the termination or expiration date of the Employee’s employment hereunder for any reason,
or for no reason, or in the event the Employee resigns, or his death or disability then, in any of such events, the Employee shall be paid his Base Salary and benefits through the date of expiration or termination and all the rights and options
granted to the Employee pursuant to Articles 3 and 4 hereof shall cease and terminate as of the date of the Employee’s termination, expiration or resignation and thereafter shall be null and void and without further force or effect.
Notwithstanding anything to the contrary herein contained, it is expressly agreed and understood that: (i) if the Employee is terminated by the Company without cause, or the Employee terminates his employment for Good Reason, as hereinafter
defined, prior to a “Change of Control” then the Employee shall be entitled to severance payments equal to twelve (12) months continuation of his Base Salary, a pro-rata share of any bonus for
which the Employee was eligible, continuation of benefits for the twelve (12) months severance period (or additional compensation in an amount reflecting the cost to the Company of such benefits if the benefit plans do not provide for
continuation) and continued vesting of stock options for twelve (12) months. 
 All severance payments of Base Salary and benefits
pursuant to subsection (i) will be paid in accordance with the provisions of this Agreement. Alternatively, if the Employee is terminated by the Company without cause, or the Employee terminates his employment for Good Reason, as hereinafter
defined, within nine (9) months following a “Change of Control,” the Employee shall be entitled to a one-time severance payment equal to twelve (12) months of his Base Salary as of the date
of termination, and such severance payment shall be paid as of the date of termination. If the Employee remains employed by the Company following the nine (9) months after a “Change of Control,” the severance benefits described in
subsection (i) shall again apply. 
 For purposes of this Agreement, “Good Reason” is defined to exist upon: 

 

	 	(A)	 The relocation of the Company’s offices such that the Employee’s daily commute is increased by at
least fifteen (15) miles each way without the written consent of the Employee; 

  

	 	(B)	 Material reduction of the Employee’s Base Salary without the prior consent of the employee (other than in
connection with, and substantially proportionate to reductions by the Company of the Base Salary of more than 50% of its employees); 

  
 6 

	 	(C)	 Material diminution in Employee’s duties, authority or responsibilities without the prior consent of the
Employee, other than changes in duties, authority or responsibilities resulting from the Employee’s misconduct; 

Provided, however, that any reduction in duties, authority or responsibilities or reduction in the level of management to which the Employee
reports resulting solely from a Change in Control which results in the Company being acquired by and made a part of a larger entity shall not constitute Good Reason. 

10.    Notice. Any notice provided for in this Agreement must be in writing and must be either personally
delivered, mailed by first class mail (postage prepaid and return receipt requested), sent by reputable overnight courier service (charges prepaid), or sent by confirmed facsimile at the address indicated below: 

 

			
	To the Company:	  	To Employee:
		
	AMYLYX PHARMACEUTICALS, INC.	  	Joshua B. Cohen
	210 Broadway #201	  	373 Columbia Street, Apt. 1
	Cambridge, MA 02139 	  	 Cambridge, MA 02141 

	Attn: Justin Klee, President	  	

 or such other address and/or to the attention of such other person as the recipient party shall have designated by notice
given in accordance with this Section 10. All notices under this Agreement shall be deemed to have been given:    (a) if delivered in person or sent by confirmed facsimile then on the date delivered, (b) if by overnight
courier, one (1) day following delivery to recipient, facsimile transmission or delivery to the courier (as the case may be) or (c) if mailed, three (3) business days following deposit in the U.S. mail. 

11.     Code Section 409A Compliance. 

(a)    The intent of the parties is that payments and benefits under this Agreement comply with, or be exempt from Code
Section 409A, and, accordingly, this Agreement shall be interpreted and applied so as to be in compliance therewith. The Company and the Executive agree to work together in good faith to consider amendments to this Agreement and to take such
reasonable actions which are necessary, appropriate or desirable to avoid imposition of any additional tax or income recognition prior to actual payment to the Executive under Section 409A. 

  
 7 

 (b)    A termination of employment shall not be deemed to have occurred
for purposes of any provision of this Agreement providing for the payment of any amounts or benefits upon or following a termination of employment that are considered “non-qualified deferred
compensation” under Code Section 409A unless such termination is also a “separation from service” within the meaning of Code 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”. If the Executive is deemed on the date of termination to be a “specified employee” within the meaning of that
term under Code Section 409A(a)(2)(B), then with regard to any payment that is considered non-qualified deferred compensation under Code Section 409A payable on account of a “separation from
service,” such payment or benefit shall be made or provided at the date which is the earlier of (A) the expiration of the six (6) -month period measured from the date of such “separation from service” of the Executive, and
(B) the date of the Executive’s death (the “Delay Period”). Upon the expiration of the Delay Period, all payments and benefits delayed pursuant to this Section 26(b) (whether they would have otherwise been payable in a single sum
or in installments in the absence of such delay) shall be paid or reimbursed to the Executive in a lump sum and any remaining payments and benefits due under this Agreement shall be paid or provided in accordance with the normal payment dates
specified for them herein. 
 (c)    With regard to any provision herein that provides for reimbursement of costs and
expenses or in-kind benefits, except as permitted by Code Section 409A, (i) the right to reimbursement or in-kind benefits shall not be subject to liquidation
or exchange for another benefit, (ii) 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, in any other taxable year, provided that the foregoing clause (ii) shall not be violated with regard to expenses reimbursed under any arrangement covered by Internal Revenue
Code Section 105(b) solely because such expenses are subject to a limit related to the period the arrangement is in effect and (iii) such payments shall be made on or before the last day of Executive’s taxable year following the
taxable year in which the expense occurred. 
 For purposes of Code Section 409A, the Executive’s right to receive any installment payments
pursuant to this Agreement shall be treated as a right to receive a series of separate and distinct payments. In no event may the Executive, directly or indirectly, designate the calendar year of any payment to be made under this Agreement that is
considered nonqualified deferred compensation. In no event shall the timing of Executive’s execution of the General Release, directly or indirectly, result in the Executive designating the calendar year of payment, and if a payment that is
subject to execution of the General Release could be made in more than one taxable year, payment shall be made in the later taxable year. 

12.     Indemnification. 

(a)    To the fullest extent permitted under applicable law, Employee shall not be liable to the Company or any of its
equity holders for any loss, claim, damage or liability arising from any act or omission performed or omitted by the Employee in connection with the Company’s business or affairs (including any error in judgment in providing any advice or
counsel), except for any loss, claim, damage or liability primarily attributable to the Employee’s willful misconduct, recklessness, or gross negligence, as finally determined by a court of competent jurisdiction, or as otherwise required by
law. 

  
 8 

 (b)    The Company shall, to the fullest extent permitted by applicable
law, indemnify and hold the Employee harmless against any and all losses, claims, damages, liabilities, costs or Expenses (as defined below) (including judgments and amounts paid in settlement) to which the Employee may become subject in connection
with any matter arising out of or in connection with the Company’s business or affairs, or by reason of the fact that the Employee is or was serving at the Company’s request as a director, officer, employee or agent of another corporation
or other enterprise, unless (i) a court of competent jurisdiction, in a judgment that has become final and that is no longer subject to appeal or review, determines that any such loss, claim, damage, liability, cost or Expense is primarily
attributable to the Employee’s willful misconduct, recklessness, or gross negligence, or (ii) it is determined in accordance with applicable law that the Employee did not act in good faith and did not reasonably believe that the
Employee’s conduct was in or not opposed to the Company’s best interests and, with respect to any criminal Proceeding (as defined below), had no reasonable cause to believe that the Employee’s conduct was unlawful. The termination of
a Proceeding by judgment, order, settlement, or conviction, or upon a plea of nolo contendere or its equivalent, is not, of itself, automatically determinative that Employee did not meet the relevant standard of conduct described in this subsection.

 (c)    If any Employee becomes involved in any capacity in any Proceeding in connection with any matter arising out
of or in connection with the Company’s business or affairs, or by reason of the fact that the Employee is or was serving at the Company’s request as an Executive Chairman, director, officer, employee or agent of another corporation or
other enterprise, the Company shall pay (as they are incurred) the Employee’s Expenses (as defined below) incurred in connection therewith after the Company receives (i) a written affinnation by the Employee of the Employee’s good
faith belief that it has met the standard of conduct necessary for indemnification, and (ii) a written undertaking by or on behalf of the Employee to repay to the Company the amount of any such Expense paid to the extent that it is ultimately
detennined that the Employee is not entitled to be indemnified by the Company in connection with such Proceeding as provided in the exceptions contained herein or under applicable law. 

(d)    If for any reason (other than anything described in Section 12(b)(i) or (ii)) the foregoing indemnification is
unavailable to the Employee, or insufficient to hold it harmless, then the Company shall, to the fullest extent permitted by applicable law, contribute to the amount paid or payable by the Employee as a result of such loss, claim, damage or
liability in such proportion as is appropriate to reflect the relative benefits received by the Company, on the one hand, and the Employee on the other hand or, if such allocation is not pennitted by applicable law, to reflect not only the relative
benefits referred to above but also any other relevant equitable considerations. 
 (e)    In any suit brought to
enforce a right to indemnification or to recover an advancement of Expenses, the burden of proving that the Employee is not entitled to be indemnified, or to an advancement of Expenses, hereunder is on the Company (or any equity holder of the
Company acting derivatively or otherwise on behalf of the Company or its equity holders). 
 (f)     As used in this
Agreement, 
 (i)    the term “Proceeding” means: (i) any threatened, pending or completed
action, suit, arbitration or other alternate dispute resolution mechanism, investigation, inquiry, judicial, administrative or legislative hearing, whether brought by or in the right of the Company or otherwise, including any and all appeals
thereof, whether of a civil, criminal, administrative, legislative, arbitrative, investigative or other nature or (ii) any inquiry, hearing or investigation that the Employee reasonably believes might lead to the institution of any such action,
suit, alternative dispute resolution mechanism or hearing, whether judicial, administrative or legislative; and 

  
 9 

 (ii)    the term “Expenses” means any and all
expenses, including attorneys’ and experts’ fees, court costs and all other expenses, paid or payable in connection with investigating, defending, being a witness in or participating in (including on appeal), or preparing to investigate,
defend, be a witness in or participate in (including on appeal), any Proceeding.” 
 13.    General
Provisions. 
 (a)    Severability.    Whenever possible, each provision of this Agreement
shall be interpreted in such manner as to be effective and valid under applicable law, but if any provision of this Agreement is held to be invalid, illegal or unenforceable in any respect under any applicable law or rule in any jurisdiction, such
invalidity, illegality or unenforceability shall not affect any other provision or any other jurisdiction, and this Agreement shall be reformed, construed and enforced in such jurisdiction so as to best give effect to the intent of the parties under
this Agreement. 
 (b)    Complete Agreement. This Agreement embodies the complete agreement and understanding
among the parties and supersedes and preempts any prior understandings, agreements or representations by or between the parties, written or oral, which may have related to the subject matter hereof in any way. 

(c)    Counterparts. This Agreement may be executed in separate counterparts, each of which is deemed to be an
original and all of which taken together constitute one and the same agreement. 
 (d)    Success and Assigns.
Except as otherwise provided herein, this Agreement shall bind and inure to the benefit of and be enforceable by the Employee and the Company, and their respective heirs, legal representatives, successors and assigns, including any successor to the
Company by means of merger or consolidation; provided that the rights and obligations of Employee under this Agreement shall not be assignable. The Company is defined to mean an affiliate or subsidiary of the Company. 

(e)    Choice of Law. This Agreement shall be governed and construed in accordance with the internal laws of the
Commonwealth of Massachusetts without giving effect to any choice of law or conflict of law provision or rule (whether of the Commonwealth of Massachusetts or any other jurisdiction) that would cause the application of the laws of any jurisdiction
other than the Commonwealth of Massachusetts. 
 (f)    Consent to Jurisdiction. The parties irrevocably consent
and submit to the jurisdiction of any local, state or federal court within the County of Middlesex and in The Commonwealth of Massachusetts for the enforcement of this Agreement. The parties irrevocably waive any objection he may have to venue in
the defense of an inconvenient forum to the maintenance of such actions or proceedings to enforce this Agreement. 

  
 10 

 (g)    Waiver. The failure of any party to enforce any of the
provisions of this Agreement shall in no way be construed as a waiver of such provisions and shall not affect the right of such party thereafter to enforce each and every provision of this Agreement in accordance with its terms. 

(h)    Headings. The headings contained in this Agreement are for convenience of reference only and shall not
affect the meaning or interpretation of this Agreement. 
 (i)    Amendments. This Agreement shall not be amended
or modified unless pursuant to an agreement in writing signed by the Company and the Employee. 
 (i)
    Survival, Notwithstanding anything to the contrary herein contained, Sections 6, 7, 8, 9, 11, 12 and 13 hereof shall remain in effect following the expiration or termination of this Agreement and Employee’s
employment hereunder and the rights and obligations of the parties shall survive the termination or expiration of Employee’s employment to the extent that any performance is required following termination or expiration of this Agreement.

bonus, if awarded, shall not be added to the Base Salary and, if awarded, will be paid within forty five (45) days after the end of the year with respect to which the bonus is being awarded. 

(c)    Stock Option Bonus. The Company agrees that, from time to time during the Employment Term, the Employee may
be eligible for additional stock option grants as determined, on an annual basis, by the Board and based upon the successful completion of annual goals and objectives as determined by the Board. All such grants shall vest in accordance with the
Company’s standard form option grant agreement. The decision of the Board as to whether or not to award any stock options shall be final and binding on the parties.

reasonable out-of-pocket business expenses, which Employee incurs in connection with performing his duties under this Agreement. The reimbursement of all such expenses
shall be made in accordance with the Company’s customary practices and policies (including presentation of evidence reasonably satisfactory to the Company of the amounts and nature of such expenses) for reimbursement of expenses. 

6.    Restrictive Covenants. As partial consideration of the Company entering into this Agreement, the Employee
agrees that at all times during which the Employee is employed by the Company and continuing for a period of one (1) year following the expiration or termination of the Employee’s employment under this Agreement for any reason (the
“Restricted Period”), the Employee shall not, directly or indirectly, without the prior written consent of the Company, any place in the world: (A) engage or participate, as an owner, partner, shareholder (except as the holder of not
more than one percent (1%) of the outstanding stock of a publicly-traded company), member, employee, adviser, consultant, sales representative, officer, director, agent or otherwise, in any Competitive Business (as defined below); (B) without

Business” shall mean a business which is directly or indirectly competitive with the business of the Company as conducted at the time of the expiration or termination of Employee’s employment. 

7.    Proprietary Rights. 

7.1    Definitions. For the purposes of this Article 7, the terms set forth below shall have the following
meanings: 
 7.11    Concept and Ideas. Those concepts and ideas disclosed by the Company to Employee or which
are first developed or conceived by Employee during the Employment Term and which relate to the Company’s present, past or prospective activities, services and products, all of which shall remain the sole and exclusive property of the Company
(hereinafter, collectively referred as “Concepts and Ideas”). Further, the Employee shall have no publication rights hereunder and all of the same shall belong exclusively to the Company. Employee acknowledges and agrees that all works and
tasks performed by Employee for or on behalf of the Company, or in connection therewith during the Employment Terms (the “Works”) are owned by the Company. Employee acknowledges and agrees that, to the fullest extent allowed by law, all of
the Works are “works made for hire,” as that phrase is defined in the Copyright Revision Act of 1976 (17 U.S.C. § 101) (the “Act”) in that either: (i) such Works are and will be prepared within the scope of this
Agreement or (ii) such Works have been and will be specifically ordered or commissioned for use as set forth in the Act. The Company shall therefore be deemed to be the sole author and owner of any and all right, title, and interest therein,
including, without limitation, all intellectual property rights.

 7.1.2.    Confidential Information. Confidential Information
means that secret or proprietary information of whatever kind or nature disclosed to Employee by or on behalf of the Company during the Employment Term (whether or not invented, discovered or developed by Employee) or first developed by Employee
hereunder or otherwise during the Employment Term, or any other information derived from the Confidential Information. Such secret or proprietary information shall include (unless such information is generally available to the public or known in the
industry through no action of Employee) information relating to the design, manufacture, application, trade secrets, know how, research and development relating to the Company’s products, materials, operating and other cost data, price lists
and data relating to the Company’s products. Such secret or proprietary information shall specifically include, without limitation, all such secret or proprietary information contained in the Company’s manuals, memoranda, plans, drawings
and designs, specifications, supply sources, customer lists and records legended or otherwise identified by the Company or the Board as Confidential Information. The Employee’s obligations with respect to Confidential Information will cease
when the Confidential Information: (i) becomes part of the public domain through no wrongful act of the Employee, or (ii) is approved for release by prior written authorization of the Company. However, Confidential Information shall be
considered Confidential Information even if a portion or specific sections of the Confidential Information are known or generally available to the general public; and the Confidential Information shall not lose its character and status as
Confidential Information unless and until all of the Confidential Information is in the public domain. 

7.2.    Non-Disclosure to Third Parties. Except as required by Employee’s duties, Employee shall not, at any
time, now or in the future, directly or indirectly, use, publish, disseminate, reproduce or otherwise disclose any Confidential Information, Concepts and Ideas relating to the present, past or prospective business of the Company to any third party.
Further, and recognizing the highly competitive nature of the Company’s business and the need to protect its intellectual property, all publication rights shall belong solely to the Company. 

  
 4 

 7.3.    Documents, etc. All documents, procedural manuals,
guides, specifications, plans, drawings, designs and similar materials, lists of present, past or prospective customers, customer proposals, invitations to submit proposals, price lists and data relating to the pricing of the Company’s products
and services, records, notebooks and similar repositories of or containing Confidential Information (including all copies thereof) that come into Employee’s possession or control by reason of Employee’s relationship with the Company,
whether prepared by Employee or others: (a) are and shall remain the property of the Company, (b) will not be used by Employee in any way adverse to the Company, (c) will not be removed from the Company’s premises (except as
Employee’s duties require) and (d) at the termination (for whatever reason) of Employee’s relationship with the Company, will be left with, or forthwith returned by Employee to, the Company. 

7.4.    Patents, etc. Any interest in patents, patent applications, inventions, technological innovations,
improvements, enhancements, copyrights, copyrightable works, developments, discoveries, designs, processes, formulas, know-how, data and analysis, whether patentable or not (collectively, the
“Inventions”), which Employee as a result of rendering the Services to the Company under this Agreement may conceive or develop shall belong exclusively to the Company. 

7.5.    Assignment. The Employee hereby irrevocably assigns and, to the extent any such assignment cannot be made
at present, hereby agrees to irrevocably and automatically assign to the Company, without further compensation or consideration of his rights, title and interest in and to all Concepts, Ideas, Works, and Inventions and any and all related patents,
patent applications, copyrights, copyright applications, licenses, trademarks, trade names and other proprietary or intellectual property rights in the United States and throughout the world. The Employee agrees that he will promptly, without any
additional costs, expense or consideration, execute when presented, whether during the Employment Term or at any time thereafter, all documents, agreements, applications and instruments and perform all lawful acts which the Company considers
necessary or advisable to secure its rights hereunder and to carry out the intent of this Agreement. 

8.    Specific Performance. Employee agrees that any violation by him of Sections 6 or 7 of this Agreement would be
highly injurious to the Company and would cause irreparable harm to the Company. By reason of the foregoing, Employee consents and agrees that if he violates or threatens to violate any provision(s) of Sections 6 or 7 of this Agreement, the Company
shall be entitled, in addition to any other rights and remedies that it may have, to apply to any court of competent jurisdiction for specific performance and/or injunctive or other equitable relief (without the requirement of posting of a bond or
other security) in order to enforce, or prevent any continuing or potential violation of, the provisions of such Section(s). The Employee also recognizes that the territorial, time and scope limitations set forth in Sections 6 and 7, as applicable,
are reasonable and are properly required and necessary for the protection of the Company and in the event that any such territorial, time or scope limitation is deemed to be unreasonable by a court of competent jurisdiction, the Company and the
Employee agree, and Employee submits, to the reduction of any or all of said territorial, time or scope limitations to such an area, period or scope as said court shall deem reasonable under the circumstances. If such partial enforcement is not
possible, the provision shall be deemed severed, and the remaining provisions of this Agreement shall remain in full force and effect. Employee acknowledges that Sections 6 and 7 of this Agreement shall survive termination or expiration of the
Employee’s employment. 

  
 5 

 9.    Termination. Notwithstanding the notice provision of
Article 1 hereof, Employee’s employment with the Company: (i) shall terminate upon the Employee’s resignation, death or disability, (ii) may be terminated without prior notice by the Board for Just Cause (as defined herein) and
(iii) may be terminated without cause by either party upon twenty (20) days prior notice to the other party as set forth in Article 1 hereof. As used in this Agreement, “Just Cause” means any of the following, as
determined by the Board, in its reasonable judgment: (1) Employee’s continuous failure or continuous refusal to perform the duties and responsibilities as are requested of him by the Company; (2) Employee’s gross negligence or
willful misconduct in the performance of Employee’s duties or (3) the commission by Employee of any act of embezzlement against Company or the commission of any felony or act involving moral turpitude. 

Except as hereinafter provided, effective as of the termination or expiration date of the Employee’s employment hereunder for any reason,
or for no reason, or in the event the Employee resigns, or his death or disability then, in any of such events, the Employee shall be paid his Base Salary and benefits through the date of expiration or termination and all the rights and options
granted to the Employee pursuant to Articles 3 and 4 hereof shall cease and terminate as of the date of the Employee’s termination, expiration or resignation and thereafter shall be null and void and without further force or effect.
Notwithstanding anything to the contrary herein contained, it is expressly agreed and understood that: (i) if the Employee is terminated by the Company without cause, or the Employee terminates his employment for Good Reason, as hereinafter
defined, prior to a “Change of Control” then the Employee shall be entitled to severance payments equal to twelve (12) months continuation of his Base Salary, a pro-rata share of any bonus for
which the Employee was eligible, continuation of benefits for the twelve (12) months severance period (or additional compensation in an amount reflecting the cost to the Company of such benefits if the benefit plans do not provide for
continuation) and continued vesting of stock options for twelve (12) months. 
 All severance payments of Base Salary and benefits
pursuant to subsection (i) will be paid in accordance with the provisions of this Agreement. Alternatively, if the Employee is terminated by the Company without cause, or the Employee terminates his employment for Good Reason, as hereinafter
defined, within nine (9) months following a “Change of Control,” the Employee shall be entitled to a one-time severance payment equal to twelve (12) months of his Base Salary as of the date
of termination, and such severance payment shall be paid as of the date of termination. If the Employee remains employed by the Company following the nine (9) months after a “Change of Control,” the severance benefits described in
subsection (i) shall again apply. 
 For purposes of this Agreement, “Good Reason” is defined to exist upon: 

 

	 	(A)	 The relocation of the Company’s offices such that the Employee’s daily commute is increased by at
least fifteen (15) miles each way without the written consent of the Employee; 

  

	 	(B)	 Material reduction of the Employee’s Base Salary without the prior consent of the employee (other than in
connection with, and substantially proportionate to reductions by the Company of the Base Salary of more than 50% of its employees); 

  
 6 

	 	(C)	 Material diminution in Employee’s duties, authority or responsibilities without the prior consent of the
Employee, other than changes in duties, authority or responsibilities resulting from the Employee’s misconduct; 

Provided, however, that any reduction in duties, authority or responsibilities or reduction in the level of management to which the Employee
reports resulting solely from a Change in Control which results in the Company being acquired by and made a part of a larger entity shall not constitute Good Reason. 

10.    Notice. Any notice provided for in this Agreement must be in writing and must be either personally
delivered, mailed by first class mail (postage prepaid and return receipt requested), sent by reputable overnight courier service (charges prepaid), or sent by confirmed facsimile at the address indicated below:

 or such other address and/or to the attention of such other person as the recipient party shall have designated by notice
given in accordance with this Section 10. All notices under this Agreement shall be deemed to have been given: (a) if delivered in person or sent by confirmed facsimile then on the date delivered, (b) if by overnight courier, one
(1) day following delivery to recipient, facsimile transmission or delivery to the courier (as the case may be) or (c) if mailed, three (3) business days following deposit in the U.S. mail. 

11.    Code Section 409A Compliance. 

(a)    The intent of the parties is that payments and benefits under this Agreement comply with, or be exempt from Code
Section 409A, and, accordingly, this Agreement shall be interpreted and applied so as to be in compliance therewith. The Company and the Executive agree to work together in good faith to consider amendments to this Agreement and to take such
reasonable actions which are necessary, appropriate or desirable to avoid imposition of any additional tax or income recognition prior to actual payment to the Executive under Section 409A. 

  
 7 

 (b)    A termination of employment shall not be deemed to have occurred
for purposes of any provision of this Agreement providing for the payment of any amounts or benefits upon or following a termination of employment that are considered “non-qualified deferred
compensation” under Code Section 409A unless such termination is also a “separation from service” within the meaning of Code 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”. If the Executive is deemed on the date of termination to be a “specified employee” within the meaning of that
term under Code Section 409A(a)(2)(B), then with regard to any payment that is considered non-qualified deferred compensation under Code Section 409A payable on account of a “separation from
service,” such payment or benefit shall be made or provided at the date which is the earlier of (A) the expiration of the six (6)- month period measured from the date of such “separation from service” of the Executive, and (B)
the date of the Executive’s death (the “Delay Period”). Upon the expiration of the Delay Period, all payments and benefits delayed pursuant to this Section 26(b) (whether they would have otherwise been payable in a single sum or
in installments in the absence of such delay) shall be paid or reimbursed to the Executive in a lump sum and any remaining payments and benefits due under this Agreement shall be paid or provided in accordance with the normal payment dates specified
for them herein. 
 (c)    With regard to any provision herein that provides for reimbursement of costs and expenses or in-kind benefits, except as permitted by Code Section 409A, (i) the right to reimbursement or in-kind benefits shall not be subject to liquidation or exchange for
another benefit, (ii) 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, in any other taxable year, provided that the foregoing clause (ii) shall not be violated with regard to expenses reimbursed under any arrangement covered by Internal Revenue
Code Section 105(b) solely because such expenses are subject to a limit related to the period the arrangement is in effect and (iii) such payments shall be made on or before the last day of Executive’s taxable year following the
taxable year in which the expense occurred. 
 For purposes of Code Section 409A, the Executive’s right to receive any installment payments
pursuant to this Agreement shall be treated as a right to receive a series of separate and distinct payments. In no event may the Executive, directly or indirectly, designate the calendar year of any payment to be made under this Agreement that is
considered nonqualified deferred compensation. In no event shall the timing of Executive’s execution of the General Release, directly or indirectly, result in the Executive designating the calendar year of payment, and if a payment that is
subject to execution of the General Release could be made in more than one taxable year, payment shall be made in the later taxable year. 

12.    Indemnification. 

(a)    To the fullest extent permitted under applicable law, Employee shall not be liable to the Company or any of its
equity holders for any loss, claim, damage or liability arising from any act or omission performed or omitted by the Employee in connection with the Company’s business or affairs (including any error in judgment in providing any advice or
counsel), except for any loss, claim, damage or liability primarily attributable to the Employee’s willful misconduct, recklessness, or gross negligence, as finally determined by a court of competent jurisdiction, or as otherwise required by
law. 

  
 8 

 (b)    The Company shall, to the fullest extent permitted by applicable
law, indemnify and hold the Employee harmless against any and all losses, claims, damages, liabilities, costs or Expenses (as defined below) (including judgments and amounts paid in settlement) to which the Employee may become subject in connection
with any matter arising out of or in connection with the Company’s business or affairs, or by reason of the fact that the Employee is or was serving at the Company’s request as a director, officer, employee or agent of another corporation
or other enterprise, unless (i) a court of competent jurisdiction, in a judgment that has become final and that is no longer subject to appeal or review, determines that any such loss, claim, damage, liability, cost or Expense is primarily
attributable to the Employee’s willful misconduct, recklessness, or gross negligence, or (ii) it is determined in accordance with applicable law that the Employee did not act in good faith and did not reasonably believe that the
Employee’s conduct was in or not opposed to the Company’s best interests and, with respect to any criminal Proceeding (as defined below), had no reasonable cause to believe that the Employee’s conduct was unlawful. The termination of
a Proceeding by judgment, order, settlement, or conviction, or upon a plea of nolo contendere or its equivalent, is not, of itself, automatically determinative that Employee did not meet the relevant standard of conduct described in this subsection.

 (c)    If any Employee becomes involved in any capacity in any Proceeding in connection with any matter arising out
of or in connection with the Company’s business or affairs, or by reason of the fact that the Employee is or was serving at the Company’s request as an Executive Chairman, director, officer, employee or agent of another corporation or
other enterprise, the Company shall pay (as they are incurred) the Employee’s Expenses (as defined below) incurred in connection therewith after the Company receives (i) a written affirmation by the Employee of the Employee’s good
faith belief that it has met the standard of conduct necessary for indemnification, and (ii) a written undertaking by or on behalf of the Employee to repay to the Company the amount of any such Expense paid to the extent that it is ultimately
determined that the Employee is not entitled to be indemnified by the Company in connection with such Proceeding as provided in the exceptions contained herein or under applicable law. 

(d)    If for any reason (other than anything described in Section 12(b)(i) or (ii)) the foregoing indemnification is
unavailable to the Employee, or insufficient to hold it harmless, then the Company shall, to the fullest extent permitted by applicable law, contribute to the amount paid or payable by the Employee as a result of such loss, claim, damage or
liability in such proportion as is appropriate to reflect the relative benefits received by the Company, on the one hand, and the Employee on the other hand or, if such allocation is not permitted by applicable law, to reflect not only the relative
benefits referred to above but also any other relevant equitable considerations. 
 (e)    In any suit brought to
enforce a right to indemnification or to recover an advancement of Expenses, the burden of proving that the Employee is not entitled to be indemnified, or to an advancement of Expenses, hereunder is on the Company (or any equity holder of the
Company acting derivatively or otherwise on behalf of the Company or its equity holders). 
 (f)    As used in this
Agreement, 
 (i)    the term “Proceeding” means: (i) any threatened, pending or completed
action, suit, arbitration or other alternate dispute resolution mechanism, investigation, inquiry, judicial, administrative or legislative hearing, whether brought by or in the right of the Company or otherwise, including any and all appeals
thereof, whether of a civil, criminal, administrative, legislative, arbitrative, investigative or other nature or (ii) any inquiry, hearing or investigation that the Employee reasonably believes might lead to the institution of any such action,
suit, alternative dispute resolution mechanism or hearing, whether judicial, administrative or legislative; and 

  
 9 

 (ii)    the term “Expenses” means any and all
expenses, including attorneys’ and experts’ fees, court costs and all other expenses, paid or payable in connection with investigating, defending, being a witness in or participating in (including on appeal), or preparing to investigate,
defend, be a witness in or participate in (including on appeal), any Proceeding.” 
 13.    General
Provisions. 
 (a)    Severability. Whenever possible, each provision of this Agreement shall be interpreted
in such manner as to be effective and valid under applicable law, but if any provision of this Agreement is held to be invalid, illegal or unenforceable in any respect under any applicable law or rule in any jurisdiction, such invalidity, illegality
or unenforceability shall not affect any other provision or any other jurisdiction, and this Agreement shall be reformed, construed and enforced in such jurisdiction so as to best give effect to the intent of the parties under this Agreement. 

(b)    Complete Agreement. This Agreement embodies the complete agreement and understanding among the parties and
supersedes and preempts any prior understandings, agreements or representations by or between the parties, written or oral, which may have related to the subject matter hereof in any way. 

(c)    Counterparts. This Agreement may be executed in separate counterparts, each of which is deemed to be an
original and all of which taken together constitute one and the same agreement. 
 (d)    Success and Assigns.
Except as otherwise provided herein, this Agreement shall bind and inure to the benefit of and be enforceable by the Employee and the Company, and their respective heirs, legal representatives, successors and assigns, including any
successor to the Company by means of merger or consolidation; provided that the rights and obligations of Employee under this Agreement shall not be assignable. The Company is defined to mean an affiliate or subsidiary of the Company. 

(e)    Choice of Law. This Agreement shall be governed and construed in accordance with the internal laws of the
Commonwealth of Massachusetts without giving effect to any choice of law or conflict of law provision or rule (whether of the Commonwealth of Massachusetts or any other jurisdiction) that would cause the application of the laws of any jurisdiction
other than the Commonwealth of Massachusetts. 
 (f)    Consent to Jurisdiction. The parties irrevocably consent
and submit to the jurisdiction of any local, state or federal court within the County of Middlesex and in The Commonwealth of Massachusetts for the enforcement of this Agreement. The parties irrevocably waive any objection he may have to
venue in the defense of an inconvenient forum to the maintenance of such actions or proceedings to enforce this Agreement. 

 (g)    Waiver. The failure of any party to enforce any of the
provisions of this Agreement shall in no way be construed as a waiver of such provisions and shall not affect the right of such party thereafter to enforce each and every provision of this Agreement in accordance with its terms. 

(h)    Headings. The headings contained in this Agreement are for convenience of reference only and shall not
affect the meaning or interpretation of this Agreement. 
 (i)    Amendments. This Agreement shall not be amended
or modified unless pursuant to an agreement in writing signed by the Company and the Employee. 
 G)    Survival.
Notwithstanding anything to the contrary herein contained, Sections 6, 7, 8, 9, 11, 12 and 13 hereof shall remain in effect following the expiration or termination of this Agreement and Employee’s employment hereunder and the rights and
obligations of the parties shall survive the termination or expiration of Employee’s employment to the extent that any performance is required following termination or expiration of this Agreement.
