 Mr. Scott Carmer 

 

	Re:	 Separation Agreement 

Dear Scott: 
 You are resigning as the Chief Executive Officer of
NexImmune, Inc. (the “Company”). The purpose of this letter agreement (this “Agreement”) is to set forth the terms of your resignation from the Company. 

 

	1.	 Separation of Employment. Your employment with Company will end effective as of
February 12, 2022 (the “Resignation Date”). From and after the Resignation Date, you will not represent yourself as an employee or agent of Company. As of the Resignation Date, you will have resigned from each and every office,
position or responsibility in which you served for Company and each of its affiliates, subsidiaries or divisions, including as a Director on Company’s Board of Directors and as Company’s Chief Executive Officer and will deliver to Company
a written letter of resignation from each and every office, position or responsibility in which you served for Company and any of its affiliates, subsidiaries or divisions in the form provided by Company. 

 

	2.	 Separation Benefit. In consideration for you signing and returning this Agreement, the
Company will provide you with $50,000.00, less applicable withholdings and other deductions, in lieu of a 2021 performance bonus (the “Separation Benefits”). The payment will be made in one lump sum on the next payroll date
following the Effective Date (as defined in Section 17 below). 

 You acknowledge that except for the Separation
Benefits, your final wages, and any accrued but unused vacation (each of which shall be paid to you in accordance with Company’s regular payroll practices and applicable law), you are not entitled to any other compensation from Company or any
of its affiliates, subsidiaries or divisions, without limitation, other wages, commissions, bonuses, vacation pay, holiday pay, equity, units, stock, stock options, carve out, paid time off or any other form of compensation or benefit. 

 

	3.	 Company Equity. You were granted options (“Options”) to purchase
shares of the Company’s common stock under the Company’s 2017 Equity Incentive Plan, the 2018 Equity Incentive Plan and the 2021 Equity Incentive Plan. In accordance with the terms of each such Plan and your award agreements, all Options
that remain unvested as of the Resignation Date will cease to vest and will be forfeited. You will have the time to exercise vested Options following the Resignation Date to extent permitted under the terms of the applicable Plan and award
agreement. 

  

	4.	 COBRA Benefits. Your coverage under the Company’s group health plans will terminate
effective February 28, 2022. Regardless of whether you sign the Agreement, you have the right to elect to continue your medical and dental benefits pursuant to the terms and conditions of COBRA at your cost. Your eligibility for benefits under
COBRA, the amount of such benefits, and the terms and conditions of such benefits, shall be determined by COBRA statutory and regulatory guidelines.

	5.	 No Other Compensation Due. You acknowledge that except for the Separation Benefits and
your final wages, including accrued, unpaid vacation time (which final wages will be paid to you in accordance with Company’s regular payroll practices and applicable law), you are not now and shall not in the future be entitled to any other
compensation from Company or any of its affiliates, subsidiaries or divisions, without limitation, other wages, commissions, bonuses, vacation pay, holiday pay, equity, units, stock, stock options, carve out, paid time off or any other form of
compensation or benefit. 

  

	6.	 Unemployment Benefits. By virtue of your separation of employment, you shall be entitled
to apply for unemployment benefits. The determination of your eligibility for such benefits (and the amount of benefits to which you may be entitled) shall be made by the appropriate state agency pursuant to applicable state law. Company agrees that
it shall not contest any claim for unemployment benefits by you. Company, of course, shall not be required to falsify any information. 

  

	7.	 Return of Property, Confidentiality, Non-Disparagement,
and Related Matters. You expressly acknowledge and agree to the following: 

  

	 	(a)	 On or prior to the Resignation Date, you will return to Company all documents (and any copies,
duplicates, or replicas thereof), and property, including, without limitation, any laptop computer that was provided to you by Company or any of its affiliates, Company’s and their respective divisions, affiliates, parents, subsidiaries and
related entities, and all of its and their owners, shareholders, partners, directors, officers, employees, trustees, agents, successors and assigns (collectively, the “Company Affiliates”) during your employment with the Company,
and that you will abide by any and all common law and/or statutory obligations relating to protection and non-disclosure of Company’s and the Company Affiliates’ trade secrets and/or confidential and
proprietary documents and information. 

  

	 	(b)	 You previously executed an Employee Proprietary Information, Inventions,
Non-Competition and Non-Solicitation Agreement, dated as of July 1, 2014 (the “Restrictions Agreement”). The Restrictions Agreement remains in full
force and effect and survives the termination of your employment with the Company. You will honor and abide by the terms and provisions of the Restrictions Agreement. 

 

	 	(c)	 You will not make any statements that are disparaging about, or adverse to, the interests or business of
Company or any Company Affiliate (including their respective officers, directors, employees, and direct or indirect shareholders) including, without limitation, any statements that disparage any person, product, service, finances, financial
condition, capability or any other aspect of the business of Company or any Company Affiliate (including their respective officers, directors, employees, and direct or indirect shareholders). “Disparaging” statements are those that,
directly or indirectly, impugn the character, honesty, integrity or morality or business acumen or abilities in connection with any aspect of the operation of business of the individual or entity being disparaged. This restriction will not restrict
your ability to testify truthfully under oath pursuant to subpoena or other legal process. 

  

	 	(d)	 Your breach of any of the foregoing covenants by you shall constitute a material breach of this
Agreement and shall relieve Company of any further obligations hereunder and, in addition to any other legal or equitable remedy available to Company and, subject to the Company obtaining a court order or judgment, the Company will be entitled to
terminate or recover any Separation Benefits already provided to you pursuant to this Agreement and to terminate the Option.
