CONSULTING AGREEMENT 

This Consulting Agreement (the “Agreement”), made this 27th day of
March, 2017 is entered into by Immunotolerance, Inc., a Delaware corporation (the “Company”), and Alan Crane, an individual (the “Consultant”). 

WHEREAS, the Company and the Consultant desire to establish the terms and conditions under which the Consultant will provide services to the
Company. 
 NOW, THEREFORE, in consideration of the mutual covenants and promises contained herein and other good and valuable
consideration, the receipt and sufficiency of which is hereby acknowledged by the parties hereto, the parties agree as follows: 
 1.
Services. The Consultant agrees to perform such consulting, advisory and related services to and for the Company as may be reasonably requested from time to time by the Company, including, but not limited to, the services specified on
Schedule A to this Agreement. The Consultant also agrees to provide the Company with related services that may be requested from time to time by the Company. During the Consultation Period (as defined below) and for a period of one year
thereafter, except in connection with his performance of the Services, the Consultant shall not engage in any activity in the field described on Schedule A to this Agreement, and he shall not assist any other person or organization that
engages in any such activity. 
 2. Term. This Agreement shall commence on the Effective Date and shall continue until the four-year
anniversary of the Effective Date (such period, as it may be extended, either by the mutual written agreement of the parties or automatically, or earlier terminated being referred to as the “Consultation Period”), unless sooner
terminated in accordance with the provisions of Section 4, and shall automatically renew for successive one-year periods, unless the Company provides 90 days’ notice of termination before any such
successive period. 
 3. Compensation. 

3.1 Shares. In connection with the execution of this Agreement, Consultant and Company shall enter into a Restricted Stock Agreement.
Subject to approval of the Board of Directors of the Company, the Company shall issue and sell to the Consultant, and the Consultant shall purchase from the Company, subject to the terms and conditions set forth in this Agreement and the Restricted
Stock Agreement, 1,990,000 shares (the “Shares”) of common stock, $0.0001 par value, of the Company (“Common Stock”), at a purchase price of $0.0001 per share, for an aggregate purchase price of $190. Such Shares are in addition
to the 10,000 shares of Common Stock held by the Consultant as of the date hereof. The Consultant agrees that the Shares shall be subject to the terms of the Restricted Stock Agreement. 

3.2 Expenses. The Company shall reimburse the Consultant for all reasonable and necessary documented out of pocket expenses incurred or
paid by the Consultant in connection with, or related to, the performance of Consultant’s services under this Agreement. 












 The Consultant shall submit to the Company itemized monthly statements, in a form satisfactory to the
Company, of such expenses incurred in the previous month. The Company shall pay to the Consultant amounts shown on each such statement within thirty (30) days after receipt thereof. 

3.3 Benefits. The Consultant shall not be entitled to any benefits, coverages or privileges, including, without limitation, health
insurance, social security, unemployment, medical or pension payments, made available to employees of the Company. 
 4. Termination.
The Company may terminate the Consultation Period at any time for Cause (as defined below). In the event of such termination, the Consultant shall be entitled to payment hereunder and for expenses paid or incurred prior to the effective date of
termination. Such payments shall constitute full settlement of any and all claims of the Consultant of every description against the Company. Notwithstanding the foregoing, the Company may terminate the Consultation Period effective immediately upon
receipt of written notice by the Consultant, if the Consultant breaches or threatens to breach any provision of Section 6. For purposes of this Section 4, “Cause” shall exist in the event of (i) a good faith finding by the
Board of Directors of the Company (A) of repeated and willful failure of the Consultant after written notice to perform his reasonable Services for the Company, or (B) that the Consultant has engaged in dishonesty, gross negligence or
misconduct; or (ii) the conviction of the Consultant of, or the entry of a pleading of guilty or nolo contendere by the Consultant to, any crime involving moral turpitude or any felony. The Consultant may terminate the Consultation Period at
any time upon thirty (30) days’ written notice. 
 5. Cooperation. The Consultant shall use Consultant’s best efforts
in the performance of Consultant’s obligations under this Agreement. The Company shall provide such access to its information and property as may be reasonably required in order to permit the Consultant to perform Consultant’s obligations
hereunder. The Consultant shall cooperate with the Company’s personnel, shall not interfere with the conduct of the Company’s business and shall observe all rules, regulations and security requirements of the Company concerning the safety
of persons and property. 
 6. Proprietary Information and Inventions. 

6.1 Proprietary Information. 

(a) The Consultant acknowledges that Consultant’s relationship with the Company is one of high trust and confidence and that in the
course of Consultant’s service to the Company, Consultant will have access to and contact with Proprietary Information. The Consultant will not disclose any Proprietary Information to any person or entity other than employees of the Company or
use the same for any purposes (other than in the performance of the services) without written approval by an officer of the Company, either during or after the Consultation Period, unless and until such Proprietary Information has become public
knowledge without fault by the Consultant.

 (b) For purposes of this Agreement, Proprietary Information shall mean, by way of
illustration and not limitation, all information, whether or not in writing, whether or not patentable and whether or not copyrightable, of a private, secret or confidential nature, owned, possessed or used by the Company, concerning the
Company’s business, business relationships or financial affairs, including, without limitation, any Invention, formula, vendor information, customer information, apparatus, equipment, trade secret, process, research, report, technical or

marketing or business plan, forecast, unpublished financial statement, budget, license, price, cost, customer, supplier or personnel information or employee list that is communicated to, learned of, developed or otherwise acquired by the Consultant
in the course of Consultant’s service as a consultant to the Company. 
 (c) The Consultant’s obligations under this
Section 6.1 shall not apply to any information that (i) is or becomes known to the general public under circumstances involving no breach by the Consultant or others of the terms of this Section 6.1, (ii) is generally disclosed to
third parties by the Company without restriction on such third parties, or (iii) is approved for release by written authorization of an officer of the Company. 

(d) The Consultant agrees that all files, documents, letters, memoranda, reports, records, data, sketches, drawings, models, laboratory
notebooks, program listings, computer equipment or devices, computer programs or other written, photographic, or other tangible material containing Proprietary Information, whether created by the Consultant or others, which shall come into
Consultant’s custody or possession, shall be and are the exclusive property of the Company to be used by the Consultant only in the performance of Consultant’s duties for the Company and shall not be copied or removed from the Company
premises except in the pursuit of the business of the Company. All such materials or copies thereof and all tangible property of the Company in the custody or possession of the Consultant shall be delivered to the Company, upon the earlier of
(i) a request by the Company or (ii) the termination of this Agreement. After such delivery, the Consultant shall not retain any such materials or copies thereof or any such tangible property. 

(e) The Consultant agrees that Consultant’s obligation not to disclose or to use information and materials of the types set forth in
paragraphs (b) and (d) above, and Consultant’s obligation to return materials and tangible property set forth in paragraph (d) above extends to such types of information, materials and tangible property of customers of the Company or

 (f) The
Consultant acknowledges that the Company from time to time may have agreements with other persons or with the United States Government, or agencies thereof, that impose obligations or restrictions on the Company regarding inventions made during the
course of work under such agreements or regarding the confidential nature of such work. The Consultant agrees to be bound by all such obligations and restrictions that are known to Consultant and to take all action necessary to discharge the
obligations of the Company under such agreements.

 6.2 Inventions. 

(a) All inventions, ideas, creations, discoveries, computer programs, works of authorship, data, developments, technology, designs,
innovations and improvements (whether or not patentable and whether or not copyrightable) which are made, conceived, reduced to practice, created, written, designed or developed by the Consultant, solely or jointly with others or under
Consultant’s direction and whether during normal business hours or otherwise, (i) during the Consultation Period if related to the business of the Company or (ii) during or after the Consultation Period if resulting or directly
derived from Proprietary Information (as defined above) (collectively under clauses (i) and (ii), “Inventions”), shall be the sole property of the Company. The Consultant hereby assigns to the Company all Inventions and any and
all related patents, copyrights, trademarks, trade names, and other industrial and intellectual property rights and applications therefor, in the United States and elsewhere and appoints any officer of the Company as Consultant’s duly
authorized attorney to execute, file, prosecute and protect the same before any government agency, court or authority. However, this paragraph shall not apply to Inventions which do not relate to the business or research and development conducted or
planned to be conducted by the Company at the time such Invention is created, made, conceived or reduced to practice and which are made and conceived by the Consultant not during normal working hours, not on the Company’s premises and not using
the Company’s tools, devices, equipment or Proprietary Information. The Consultant further acknowledges that each original work of authorship which is made by the Consultant (solely or jointly with others) within the scope of this Agreement and
which is protectable by copyright is a “work made for hire,” as that term is defined in the United States Copyright Act. 
 (b)
The Consultant agrees that if, in the course of performing the Services, the Consultant incorporates into any Invention developed under this Agreement any preexisting invention, improvement, development, concept, discovery or other proprietary
information owned by the Consultant or in which the Consultant has an interest (“Prior Inventions”), (i) the Consultant will inform the Company, in writing before incorporating such Prior Inventions into any Invention, and
(ii) the Company is hereby granted a nonexclusive, royalty-free, perpetual, irrevocable, transferable worldwide license with the right to grant and authorize sublicenses, to make, have made, modify, use, import, offer for sale, sell, reproduce,
distribute, modify, adapt, prepare derivative works of, display, perform, and otherwise exploit such Prior Inventions, without restriction, including, without limitation, as part of or in connection with such Invention, and to practice any method
related thereto. The Consultant will not incorporate any invention, improvement, development, concept, discovery or other proprietary information owned by any third party into any Invention without the Company’s prior written permission. 

(c) Upon the request of the Company and at the Company’s expense, the Consultant shall execute such further assignments, documents and
other instruments as may be necessary or desirable to fully and completely assign all Inventions to the Company and to assist the Company in applying for, obtaining and enforcing patents or copyrights or other rights in the United States and in any
foreign country with respect to any Invention. The Consultant also hereby waives all claims to moral rights in any Inventions. 
 (d) The
Consultant shall promptly disclose to the Company all Inventions and will maintain adequate and current written records (in the form of notes, sketches, drawings and as may be specified by the Company) to document the conception and/or first actual
reduction to practice of any Invention. Such written records shall be available to and remain the sole property of the Company at all times.

 7. Non-Solicitation. During the Consultation
Period and for a period of one year thereafter, the Consultant shall not, either alone or in association with others, (i) solicit, or permit any organization directly or indirectly controlled by the Consultant to solicit, any employee of the
Company to leave the employ of the Company; or (ii) solicit for employment, hire or engage as an independent contractor, or permit any organization directly or indirectly controlled by the Consultant to solicit for employment, hire or engage as
an independent contractor, any person who is employed or engaged by the Company; provided, that this clause (ii) shall not apply to any individual whose employment with the Company has been terminated for a period of six months or
longer. 
 8. Other Agreements; Warranty. 

8.1 The Consultant hereby represents that, except as the Consultant has disclosed in writing to the Company, the Consultant is not bound by the
terms of any agreement with any third party to refrain from using or disclosing any trade secret or confidential or proprietary information in the course of Consultant’s consultancy with the Company, to refrain from competing, directly or
indirectly, with the business of such third party or to refrain from soliciting employees, customers or suppliers of such third party. The Consultant further represents that Consultant’s performance of all the terms of this Agreement and the
performance of the services as a consultant of the Company do not and will not breach any agreement with any third party to which the Consultant is a party (including, without limitation, any nondisclosure or
non-competition agreement), and that the Consultant will not disclose to the Company or induce the Company to use any confidential or proprietary information or material belonging to any current or previous
employer or others. 
 8.2 The Consultant hereby represents, warrants and covenants that Consultant has the skills and experience necessary
to perform the services, that Consultant will perform said services in a professional, competent and timely manner, that Consultant has the power to enter into this Agreement and that Consultant’s performance hereunder will not infringe upon or
violate the rights of any third party or violate any federal, state or municipal laws. 
 9. Independent Contractor Status. 

9.1 The Consultant shall perform all services under this Agreement as an “independent contractor” and not as an employee or agent of
the Company. The Consultant is not authorized to assume or create any obligation or responsibility, express or implied, on behalf of, or in the name of, the Company or to bind the Company in any manner. 

9.2 The Consultant shall have the right to control and determine the time, place, methods, manner and means of performing the services. In
performing the services, the amount of time devoted by the Consultant on any given day will be entirely within the Consultant’s control, and the Company will rely on the Consultant to put in the amount of time necessary to fulfill the
requirements of this Agreement. The Consultant will provide all equipment and supplies required to perform the services. The Consultant is not required to attend regular meetings at the Company. However, upon reasonable notice, the Consultant shall
meet with representatives of the Company at a location to be designated by the parties to this Agreement.

 9.3 In the performance of the services, the Consultant has the authority to control and
direct the performance of the details of the services, the Company being interested only in the results obtained. However, the services contemplated by the Agreement must meet the Company’s standards and approval and shall be subject to the
Company’s general right of inspection and supervision to secure their satisfactory completion. 
 9.4 The Consultant shall not use the
Company’s trade names, trademarks, service names or service marks without the prior approval of the Company. 
 9.5 The Consultant shall
be solely responsible for all state and federal income taxes, unemployment insurance and social security taxes in connection with this Agreement and for maintaining adequate workers’ compensation insurance coverage. 

10. Remedies. The Consultant acknowledges that any breach of the provisions of Section 1, 6 or 7 of this Agreement shall result in
serious and irreparable injury to the Company for which the Company cannot be adequately compensated by monetary damages alone. The Consultant agrees, therefore, that, in addition to any other remedy the Company may have, the Company shall be
entitled to enforce the specific performance of this Agreement by the Consultant and to seek both temporary and permanent injunctive relief (to the extent permitted by law) without the necessity of proving actual damages or posting a bond. 

11. Notices. All notices required or permitted under this Agreement shall be in writing and shall be deemed effective upon personal
delivery or upon deposit in the United States Post Office, by registered or certified mail, postage prepaid, addressed to the other party at the address shown above, or at such other address or addresses as either party shall designate to the other
in accordance with this Section 11. 
 12. Pronouns. Whenever the context may require, any pronouns used in this Agreement shall
include the corresponding masculine, feminine or neuter forms, and the singular forms of nouns and pronouns shall include the plural, and vice versa. 

13. Entire Agreement. This Agreement constitutes the entire agreement between the parties and supersedes all prior agreements and
understandings, whether written or oral, relating to the subject matter of this Agreement. 
 14. Amendment. This Agreement may be
amended or modified only by a written instrument executed by both the Company and the Consultant. 
 15.
Non-Assignability of Contract. This Agreement is personal to the Consultant and the Consultant shall not have the right to assign any of Consultant’s rights or delegate any of Consultant’s
duties without the express written consent of the Company. Any non-consented-to assignment or delegation, whether express or implied or by operation of law, shall be
void and shall constitute a breach and a default by the Consultant. 

  
 - 6 - 













 16. Governing Law. This Agreement shall be governed by and construed in accordance
with the laws of the Commonwealth of Massachusetts without giving effect to any choice or conflict of law provision or rule that would cause the application of laws of any other jurisdiction. 

17. Successors and Assigns. This Agreement shall be binding upon, and inure to the benefit of, both parties and their respective
successors and assigns, including any corporation with which, or into which, the Company may be merged or which may succeed to its assets or business, provided, however, that the obligations of the Consultant are personal and shall not be assigned
by Consultant. 
 18. Interpretation. If any restriction set forth in Section 1, 6 or 7 is found by any court of competent
jurisdiction to be unenforceable because it extends for too long a period of time or over too great a range of activities or in too broad a geographic area, it shall be interpreted to extend only over the maximum period of time, range of activities
or geographic area as to which it may be enforceable. 
 19. Survival. The last sentence of Section 1 and Sections 4 through 20
shall survive the expiration or termination of this Agreement. 
 20. Miscellaneous. 

20.1 No delay or omission by the Company in exercising any right under this Agreement shall operate as a waiver of that or any other right. A
waiver or consent given by the Company on any one occasion shall be effective only in that instance and shall not be construed as a bar or waiver of any right on any other occasion. 

20.2 The captions of the sections of this Agreement are for convenience of reference only and in no way define, limit or affect the scope or
substance of any section of this Agreement. 
 20.3 In the event that any provision of this Agreement shall be invalid, illegal or otherwise
unenforceable, the validity, legality and enforceability of the remaining provisions shall in no way be affected or impaired thereby.
