January 19, 2019

Katrine Bosley

Dear Katrine:

I am writing to confirm the arrangements with respect to your transition and separation from employment with Editas Medicine, Inc. (the “Company”).

As we have discussed, provided you sign and return this letter agreement to me by January 21, 2019, you will have the opportunity to remain employed by the Company as President and Chief Executive Officer through March 1, 2019 (the “Separation Date”), pursuant to the terms and conditions set forth below, with your resignation from such employment and offices effective on that date. We agree that all public communication by the Company regarding your resignation will be substantially consistent with the press release in the form attached hereto as Attachment 1. Further, provided you sign and return the Additional Release of Claims attached hereto as Exhibit A (the “Additional Release”) on the Separation Date and do not revoke the Additional Release, you will have the opportunity to receive the post-separation consideration described in paragraph 2 below.

By timely signing and returning this letter agreement, and by timely signing and returning the Additional Release and not revoking your acceptance, you will be entering into binding agreements with the Company and will be agreeing to the terms and conditions set forth in the numbered paragraphs below, including the releases of claims set forth in paragraph 3 and in the Additional Release. Therefore, you are advised to consult with an attorney before signing this letter agreement or the Additional Release, and you have been given a reasonable amount of time to consider this letter agreement, and at least twenty-one (21) days to consider the Additional Release. If you sign the Additional Release, you may change your mind and revoke your agreement during the seven (7) day period after you have signed it (the “Revocation Period”) by notifying me in writing. If you do not so revoke, the Additional Release will become a binding agreement between you and the Company upon the expiration of the Revocation Period.

The following sets forth the terms and conditions that will apply should you timely sign and return this letter agreement:

1. Resignation; Transition Period – You hereby resign (a) effective as of the Separation Date, from employment with, and from your offices as President and Chief Executive Officer of, the Company, and (b) effective immediately as of the date you sign this letter agreement, from your membership on the Company’s Board of Directors (the “Board”), and from any and all other positions as an officer of the Company and/or a member of any Board committees of the Company and any positions with Editas Securities Corporation. You further agree to execute and deliver any documents reasonably necessary to effectuate such resignations described in the previous sentence, as requested by the Company. The period between the date you sign and return this letter

agreement and the Separation Date will be a transition period (the “Transition Period”), during which you will perform transition duties as may be reasonably requested by and at the direction of the Board, which will entail assisting with the transition of your duties and responsibilities to an interim Chief Executive Officer (collectively, the “Transition Duties”) and the interim CEO will be responsible for all Company decisions during this period. Further, for purposes of clarity, you will not be required to sign any documents as CEO of the Company. Also, during the Transition Period, you will not work from the offices of the Company except as occasionally requested by the Chairman of the Board or the interim CEO. During the Transition Period, you will continue to receive your regular base salary at its current rate, to participate in the Company’s benefit plans (pursuant to the terms and conditions of such plans), and to be entitled to vacation time in accordance with Company policy; provided, however, that you will not be eligible for or entitled to participate in any Company bonus plan for the 2019 fiscal year or future fiscal years. You will, however, be eligible to receive a bonus for 2018 equal to your target bonus times the percentage achievement of the Company’s 2018 goals as assessed by the Board of Directors of the Company in connection with the determination of bonuses for the executive team, with any such bonus to be payable to you in the first quarter of 2019, no later than March 15, 2019. Notwithstanding any of the foregoing, the Company retains the right to terminate your employment prior to the Separation Date for Cause (as defined in the Company’s Severance Benefits Plan adopted on December 10, 2015 (the “Severance Plan”), in which case your employment with the Company shall end immediately and you will not be eligible to receive any further payment, including bonus, or benefit from the Company, except for your final wages and any unused vacation time accrued through the last day of your employment and, if eligible and at your own cost, group medical insurance pursuant to the law known as “COBRA”.

2. Post-Separation Consideration – If you timely sign and return this letter agreement, continue employment through the Transition Period in accordance with the terms hereof, and timely sign and return the Additional Release (and do not revoke your acceptance within the Revocation Period), you will be eligible to receive the following:

(a) COBRA Contribution. Should you timely elect and be eligible to continue receiving group health and/or dental insurance pursuant to applicable “COBRA” law, the Company will, until the earlier of (x) February 28, 2020, and (y) the date on which you become eligible to receive group health insurance from a new employer (as applicable, the “COBRA Contribution Period”), continue to pay on your behalf the share of the premiums for such coverage that it pays on behalf of active and similarly situated employees who receive the same type of coverage and any administrative fee. The remaining balance of any premium costs during the COBRA Contribution Period, and all premium costs thereafter, shall be paid by you on a monthly basis for as long as, and to the extent that, you remain eligible for COBRA continuation. You agree that, should you obtain alternative health and/or dental insurance coverage prior to February 28, 2020, you will so inform the Company in writing within five (5) business days of obtaining such coverage.

(b) Advisory Services Agreement. The Company will engage you as an advisor pursuant to the terms set forth in the fully executed Advisory Services Agreement attached hereto as Exhibit B (the “Advisory Agreement”).

(e) The Advisor 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 Advisor agrees to be bound by all such obligations and restrictions that are known to Advisor and to take all action necessary to discharge the obligations of the Company under such agreements.

(f) The Advisor’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 Advisor 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, (iii) is approved for release by written authorization of an officer of the Company, or (iv) is independently learned by the Advisor with no reliance on any propriety information or resources of the Company. Further, nothing herein prohibits the Advisor from communicating with government agencies about possible violations of federal, state, or local laws or otherwise providing information to government agencies or participating in government agency investigations or proceedings. In addition, notwithstanding the Advisor’s confidentiality and nondisclosure obligations, the Advisor is hereby advised as follows pursuant to the Defend Trade Secrets Act: “An individual shall not be held criminally or civilly liable under any Federal or State trade secret law for the disclosure of a trade secret that (A) is made (i) in confidence to a

Federal, State, or local government official, either directly or indirectly, or to an attorney; and (ii) solely for the purpose of reporting or investigating a suspected violation of law; or (B) is made in a complaint or other document filed in a lawsuit or other proceeding, if such filing is made under seal. An individual who files a lawsuit for retaliation by an employer for reporting a suspected violation of law may disclose the trade secret to the attorney of the individual and use the trade secret information in the court proceeding, if the individual (A) files any document containing the trade secret under seal; and (B) does not disclose the trade secret, except pursuant to court order.”

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 Advisor, solely or jointly with others or under Advisor’s direction and whether during normal business hours or otherwise, (i) during the Advisory Period if related to the business of the Company or (ii) after the Advisory Period if resulting or directly derived from Proprietary Information (as defined below) (collectively under clauses (i) and (ii), “Inventions”), shall be the sole property of the Company. The Advisor 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 Advisor’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 Advisor not during normal working hours, not on the Company’s premises and not using the Company’s tools, devices, equipment or Proprietary Information. The Advisor further acknowledges that each original work of authorship which is made by the Advisor (solely or jointly with others) within the scope of the 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 Advisor agrees that if, in the course of performing the services pursuant to this Agreement, the Advisor incorporates into any Invention developed under this Agreement any preexisting invention, improvement, development, concept, discovery or other proprietary information owned by the Advisor or in which the Advisor has an interest (“Prior Inventions”), (i) the Advisor 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 Advisor 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 Advisor 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 Advisor also hereby waives all claims to moral rights in any Inventions.

(d) The Advisor 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-Exclusivity. The Company retains the right to contract with other companies and/or individuals for advising services without restriction. Similarly, the Advisor retains the right, subject to the Advisor’s continuing obligations under the Restrictive Covenant Agreements referenced in the Separation Agreement, to contract with other companies or entities for the Advisor’s advising services.

8. Other Agreements; Warranty.

8.1 The Advisor hereby represents that, except as the Advisor has previously disclosed in writing to the Company, the Advisor 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 Advisor’s advising 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 Advisor further represents that Advisor’s performance of all the terms of this Agreement and the performance of the services as an Advisor of the Company do not and will not breach any agreement with any third party to which the Advisor is a party (including, without limitation, any nondisclosure or non-competition agreement), and that the Advisor 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 Advisor hereby represents, warrants and covenants that Advisor has the skills and experience necessary to perform the services, that Advisor will perform said services in a professional, competent and timely manner, that Advisor has the power to enter into this Agreement and that Advisor’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 Advisor shall perform all services under this Agreement as an “independent contractor” and not as an employee or agent of the Company. The Advisor 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 Advisor shall have the right to control and determine the time, place, methods, manner and means of performing the services within reasonable business hours. In performing the services, the amount of time devoted by the Advisor on any given day will be entirely within the Advisor’s control, and the Company will rely on the Advisor to put in the amount of time necessary to fulfill the requirements of this Agreement, subject to the maximum number of hours per month as stated above. The Advisor is not required to attend regular meetings at the Company. However, upon reasonable notice, the Advisor 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 Advisor 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 Advisor shall not use the Company’s trade names, trademarks, service names or service marks without the prior approval of the Company.

9.5 The Advisor 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. The Advisor shall indemnify, defend and hold harmless the Company and its successors and assigns from and against any claim or liability of any kind (including penalties, fees or charges) resulting from the Advisor’s failure to pay the taxes, penalties, and payments referenced in this Section 10.

10. Remedies. The Advisor acknowledges that any breach of the provisions of Sections 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 Advisor 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 Advisor 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 12.

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 (provided, for the avoidance of doubt, that it does not

supersede the Separation Agreement or the Restrictive Covenant Agreements referenced therein).

14. Amendment. This Agreement may be amended or modified only by a written instrument executed by both the Company and the Advisor.

15. Non-Assignability of Contract. This Agreement is personal to the Advisor and the Advisor shall not have the right to assign any of Advisor’s rights or delegate any of Advisor’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 Advisor.

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 Advisor are personal and shall not be assigned by Advisor.

18. Interpretation. If any restriction set forth in Section 6 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. 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.
