AMENDED AND RESTATED EXECUTIVE EMPLOYMENT AGREEMENT 

This Amended and Restated Employment Agreement (this “Agreement”) is entered into as of the last date set forth on the
signature page below (the “Effective Date”) by and between LogicBio Therapeutics, Inc. (the “Company”) and Frederic Chereau (“Executive”). 

1. Duties and Scope of Employment. 

(a) Positions and Duties. The Company hereby agrees to continue to employ Executive as its President and Chief Executive Officer, and
Executive will hereby agrees to continue in such position and serve the Company in such capacity, during the Employment Term. Executive will render such business and professional services in the performance of his duties, consistent with
Executive’s position within the Company, as will reasonably be assigned to Executive by the Company’s Board of Directors (the “Board”). The period of Executive’s employment under this Agreement is referred to herein
as the “Employment Term.” 
 (b) Obligations. During the Employment Term, Executive will perform his duties
faithfully and to the best of his ability and will devote his full business efforts and time to the Company. For the duration of the Employment Term, Executive agrees not to actively engage in any other employment, occupation or consulting activity
for any direct or indirect remuneration without the prior approval of the Board. 
 2. At-Will
Employment. The parties agree that Executive’s employment with the Company will continue to be “at-will” employment and may be terminated at any time with or without cause or notice.
However, as described in this Agreement, Executive may be entitled to severance benefits depending on the circumstances of Executive’s termination of employment with the Company. 

3. Compensation. 
 (a)
Base Salary. During the Employment Term, the Company will pay Executive an annual salary (the “Base Salary”) of $510,000 as compensation for Executive’s services. The Base Salary will be paid periodically in accordance
with the Company’s normal payroll practices. Executive’s Base Salary will be subject to review by the Compensation Committee (the “Compensation Committee”) of the Board and adjustments to the Base Salary may be made in its
discretion. 
 (b) Bonus. During the Employment Term, Executive will be eligible to receive an annual bonus, with a target annual
bonus equal to 50 percent (50%) of the Base Salary, upon achievement of certain performance objectives to be determined by the Compensation Committee. The amount, terms and conditions of any annual bonus will be determined by the Compensation
Committee in its discretion and any annual bonus will be subject to the terms and conditions of the applicable Company bonus plan, as in effect from time to time. Any earned annual bonus will be paid as soon as reasonably practicable after the
Compensation Committee determines that such bonus has been earned, but in no event shall the bonus be paid after the March 15th following the end of the calendar year to which the bonus relates,
in accordance with the Company’s normal payroll practices. The payment of any annual bonus will be subject to Executive’s continued employment through the payment date, except as set forth in Section 6 or 7 below or as otherwise
provided in an applicable bonus plan. 
  

 (c) Equity Compensation. During the Employment Term, Executive will be eligible to
receive equity and equity-based awards in the discretion of the Board or the Compensation Committee and on such terms and conditions as are determined by the Board or the Compensation Committee in its discretion. Any equity and equity-based awards
granted to Executive, whether before or after the Effective Date, will be governed by the terms and conditions of the applicable Company equity incentive plan(s), as in effect from time to time, and the award agreements governing such equity or
equity-based awards (any such plan and award agreements, collectively, the “Equity Agreements”). Notwithstanding anything in the Equity Agreements to the contrary, Executive may exercise any options to purchase common stock of the
Company granted to him prior to the Effective Date for eighteen (18) months following the date Executive’s employment with the Company is terminated for any reason other than Cause (as defined below) or, if earlier, until the applicable
option terminates in accordance with its terms (determined without regard to Executive’s termination of employment). 
 (d) Employee
Benefits. During the Employment Term, Executive will be entitled to participate in the employee benefit plans maintained by the Company, as in effect from time to time, of general applicability to other senior executives of the Company. The
Company reserves the right to cancel or change any of its employee benefit plans at any time. 
 (e) Indemnification. Executive will
be entitled to the same indemnification rights as the Company grants to other senior executives of the Company, subject to the provisions of the Company’s by-laws and certificate of incorporation. 

4. Vacation. Executive will be entitled to earn paid annual vacation in accordance with Company policy for other senior executive
officers, as in effect from time to time. 
 5. Expenses. 

(a) Subject to Section 5(b), the Company will reimburse Executive for all reasonable and necessary expenses incurred by Executive in
connection with the performance of Executive’s duties hereunder. 
 (b) Subject to any applicable policy established by the Company as
in effect from time to time, the Company will reimburse Executive for expenses incurred pursuant to Section 5(a) upon Executive’s having submitted valid receipts to the Company, provided that Executive is an employee of the Company on the
date on which the expenses are incurred. Executive’s right to payment or reimbursement for expenses hereunder shall be subject to the following additional rules: (i) the amount of expenses eligible for payment or reimbursement during any
calendar year shall not affect the expenses eligible for payment or reimbursement in any other calendar year, (ii) payment or reimbursement shall be made not later than December 31 of the calendar year following the calendar year in which
the expense or payment was incurred, and (iii) the right to payment or reimbursement is not subject to liquidation or exchange for any other benefit.

 6. Severance. 

(a) Termination for other than Cause, Death or Disability or Resignation for Good Reason. If the Company (or any parent or subsidiary or
successor of the Company) terminates Executive’s employment with the Company other than for Cause (as defined below) and other than due to Executive’s death or Disability (as defined below), or Executive resigns with Good Reason (as
defined below), then, subject to Section 8, Executive will be entitled to (i) receive severance pay at a rate equal to Executive’s Base Salary, as then in effect, for nine (9) months from the date of such termination, which will
be paid in equal installments in accordance with the Company’s normal payroll practices; (ii) an amount equal to Executive’s target annual bonus for the year in which such termination of employment occurs, multiplied by .75, payable
in equal installments in accordance with the Company’s normal payroll practices over nine (9) months from the date of such termination; and (iii) if Executive elects continuation coverage pursuant to the Consolidated Omnibus Budget
Reconciliation Act of 1985, as amended (“COBRA”), for Executive and his eligible dependents within the time period prescribed pursuant to COBRA, the Company will reimburse Executive for the COBRA premiums for such coverage until the
earlier of (A) a period of six (6) months from the last date of employment of Executive with the Company, or (B) the date upon which Executive ceases to be eligible for coverage under COBRA. COBRA reimbursements will be made by the
Company to Executive consistent with the Company’s normal expense reimbursement policy. However, if the Company determines in its sole discretion that it cannot provide the foregoing COBRA benefits without potentially violating applicable law
(including, without limitation, Section 2716 of the Public Health Service Act) or incurring additional taxes, the Company will in lieu thereof provide to Executive a taxable monthly payment in an amount equal to the monthly COBRA premium that
Executive would be required to pay to continue his group health coverage in effect on the date of his termination of employment (which amount will be based on the premium for the first month of COBRA coverage) for the time period described in clause
(A) in equal installments in accordance with the Company’s normal payroll practices. In addition to the amounts described above, Executive will be entitled to receive Executive’s accrued and unpaid Base Salary through the date
Executive’s employment terminates, any unreimbursed expenses due under Section 5 of above, and any vested benefits required to be paid or provided under the terms and conditions of the Company’s benefit plans (collectively, the
“Accrued Benefits”) if Executive’s employment terminates in the circumstances described in this Section 6(a). 

(b) Termination for Cause or Death or Disability; Voluntary Resignation. If Executive’s employment with the Company (or any parent
or subsidiary or successor of the Company) is terminated voluntarily by Executive without Good Reason, for Cause by the Company or due to Executive’s death or Disability, then Executive will be entitled to receive the Accrued Benefits and no
further compensation or benefits will be paid to Executive under this Agreement. 
 (c) Exclusive Remedy. In the event of a
termination of Executive’s employment with the Company (or any parent or subsidiary or successor of the Company), the provisions of this Section 6 and Section 7 below are intended to be and are exclusive and in lieu of any other
rights or remedies to which Executive or the Company may otherwise be entitled in connection with the termination of Executive’s employment under any employee compensation or benefit plan which provides benefits in the nature of severance or
continuation pay.

 7. Termination for other than Cause, Death or Disability or Resignation for Good Reason
within 24 months following a Change in Control. If the Company (or any parent or subsidiary or successor of the Company) terminates Executive’s employment with the Company other than for Cause (as defined below) and other than due to
Executive’s death or Disability (as defined below), or Executive resigns with Good Reason (as defined below), in either case, within twenty-four (24) months following a Change of Control (as defined below) then, subject to Section 8
and in lieu of the payments set forth in Section 6 above, Executive will be entitled to (i) receive a severance payment equal to one and one-half times (1.5x) the sum of (A) Executive’s
annual Base Salary, as then in effect, and (B) Executive’s target annual bonus for the year in which such termination of employment occurs; (ii) an amount equal to the monthly COBRA premium that Executive would be required to pay to
continue his group health coverage in effect on the date of his termination of employment for a period of twelve (12) months (which amount will be based on the premium for the first month of COBRA coverage); and (iii) accelerated vesting
as to one hundred percent (100%) of Executive’s then outstanding and unvested equity and equity-based awards (with any performance-vesting awards vesting at target levels). All amounts payable under prongs (i) and (ii) of this
Section 7 will be paid in a lump sum on the first normal payroll date of the Company following the Release Deadline (as defined below) in accordance with the Company’s normal payroll practices. In addition to the amounts described above,
Executive will be entitled to receive the Accrued Benefits. 
 8. Conditions to Receipt of Severance; No Duty to Mitigate. 

(a) Separation Agreement and Release of Claims. The receipt of any severance pursuant to Sections 6 or 7 will be subject to Executive
signing and not revoking a separation agreement and general release of claims in a form reasonably satisfactory to the Company (the “Release”) and provided that such Release becomes effective and irrevocable no later than sixty
(60) days following the termination date (such deadline, the “Release Deadline”). If the Release does not become effective and irrevocable by the Release Deadline, Executive will forfeit any rights to severance or benefits
under this Agreement. In no event will severance payments or benefits be paid or provided until the Release becomes effective and irrevocable. Subject to Section 8(b), any cash severance pay to which Executive is entitled pursuant to
Section 6 or 7 (other than the Accrued Obligations) will be paid, or will begin to be paid, on the first normal payroll date of the Company following the Release Deadline, with such payment to include all amounts that would have been paid prior
to such date but for this Section 8(a). 
 (b) Section 409A.  

(i) Notwithstanding anything to the contrary in this Agreement, no severance pay or benefits to be paid or provided to Executive, if any,
pursuant to this Agreement that, when considered together with any other payments or benefits, would be considered deferred compensation under Code Section 409A and the final regulations and any guidance promulgated thereunder (collectively,
“Section 409A”) (together, the “Deferred Payments”) will be paid or otherwise provided until Executive has incurred a “separation from service” within the meaning of Section 409A.

  
 -4- 

 (ii) Notwithstanding anything to the contrary in this Agreement, if Executive is a
“specified employee” within the meaning of Section 409A at the time of Executive’s termination (other than due to death), then the Deferred Payments that are payable within the first six (6) months following Executive’s
separation from service, will become payable on the first payroll date that occurs on or after the date six (6) months and one (1) day following the date of Executive’s separation from service. All subsequent Deferred Payments, if
any, will be payable in accordance with the payment schedule applicable to each payment or benefit. Notwithstanding anything herein to the contrary, if Executive dies following Executive’s separation from service, but prior to the six
(6) month anniversary of the separation from service, then any payments delayed in accordance with this paragraph will be payable in a lump sum as soon as administratively practicable after the date of Executive’s death and all other
Deferred Payments will be payable in accordance with the payment schedule applicable to each payment or benefit. Each payment and benefit payable under this Agreement is intended to constitute a separate payment for purposes of Section 1.409A-2(b)(2) of the Treasury Regulations. 
 (iii) Any amounts paid under this Agreement
that satisfies the requirements of the “short-term deferral” rule set forth in Section 1.409A-1(b)(4) of the Treasury Regulations will not constitute Deferred Payments for purposes of clause
(i) above. 
 (iv) Any amount paid under this Agreement that qualifies as a payment made as a result of an involuntary separation from
service pursuant to Section 1.409A-1(b)(9)(iii) of the Treasury Regulations that does not exceed the Section 409A Limit (as defined below) will not constitute Deferred Payments for purposes of clause
(i) above. 
 (v) All payments under this Agreement are intended to be exempt from, or comply with, the requirements of
Section 409A so that none of the payments and benefits provided hereunder will be subject to the additional tax imposed under Section 409A, and any ambiguities herein will be interpreted to so comply. The Company and 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
Executive under Section 409A. In no event will the Company, any of its subsidiaries or affiliates be liable to Executive by reason of any acceleration of income or any additional tax (including any interest and penalties) asserted with respect
to the failure of any payments or benefits provided under this Agreement to satisfy the applicable requirements of Section 409A. 
 (c)
Confidential Information Agreement. Executive’s continuing receipt of any payments or benefits under Section 6 or 7 will be subject to Executive continuing to comply with the terms of Confidential Information Agreement (as defined
in Section 11). In the event Executive breaches the provisions of the Confidential Information Agreement and is unable to cure such breach, if curable, within thirty (30) days following receipt from the Company of written notice of such
breach, then all payments and benefits to which Executive may otherwise be entitled pursuant to Sections 6 or 7 will immediately cease. 

(d) No Duty to Mitigate. Executive will not be required to mitigate the amount of any payment contemplated by this Agreement, nor will
any earnings that Executive may receive from any other source reduce any such payment.

 9. Definitions. 

(a) Cause. For purposes of this Agreement, “Cause” is defined, as determined by the Company in its reasonable judgment,
as (i) breach of this Agreement or the Confidential Information Agreement by Executive; (ii) intentional and continued nonperformance or misperformance of Executive’s duties or refusal to abide by or comply with the reasonable
directives of the Board, or the Company’s policies and procedures, which, if reasonably susceptible to cure (as determined by the Company), is not cured within fifteen (15) days following Executive’s receipt of written notice from the
Company describing in reasonable detail the nature of the nonperformance, misperformance or refusal, as applicable; (iii) Executive’s gross negligence in the performance of his material duties under this Agreement;
(iv) Executive’s fraud or willful misconduct with respect to the business or affairs of the Company; (v) Executive’s conviction of, or a plea of nolo contendere to, a felony or other crime involving moral turpitude; or
(vi) the commission of any act in direct or indirect competition with or materially detrimental to the best interests of Company. For purposes of this Agreement, any act, or failure to act, shall not be deemed willful or intentional unless it
is done, or omitted to be done, by Executive in bad faith or without a reasonable good faith belief that Executive’s action or omission was in the best interests of the Company. Notwithstanding the preceding sentence, in order for an event to
qualify as “Cause”, the Company must not terminate Executive’s employment with the Company without first providing Executive with written notice of the acts or omissions constituting the grounds for “Cause”. 

(b) Change of Control. For purposes of this Agreement, “Change of Control” is defined as: 

(i) the acquisition of the Company by another entity by means of any transaction or series of related transactions (including, without
limitation, any reorganization, merger or consolidation or stock transfer, but excluding any such transaction effected primarily for the purpose of changing the domicile of the Company), unless the Company’s stockholders of record immediately
prior to such transaction or series of related transactions hold, immediately after such transaction or series of related transactions, at least fifty percent (50%) of the voting power of the surviving or acquiring entity (provided that the
sale by the Company of its securities for the primary purpose of raising additional funds shall not constitute a Change of Control hereunder); or 

(ii) a sale, license or other disposition of all or substantially all of the assets, intellectual property or technology of the Company. 

Notwithstanding the foregoing provisions of this definition, a transaction will not be deemed a Change of Control unless the transaction
qualifies as a “change in control event” within the meaning of Section 409A. 
 (c) Code. For purposes of this
Agreement, “Code” means the Internal Revenue Code of 1986, as amended. 
 (d) Disability. For purposes of this
Agreement, “Disability” means that Executive has been unable to perform Executive’s Company duties as the result of Executive’s incapacity due to physical or mental illness for at least
twenty-six (26) weeks after the commencement of such incapacity or for one-hundred and eighty (180) days in any consecutive twelve (12) month period,
which incapacity is determined to be total and permanent by a physician selected by the Company or its insurers and acceptable to Executive or Executive’s legal representative (such agreement as to acceptability not to be unreasonably
withheld). 

  
 -6- 

 (e) Good Reason. For purposes of this Agreement, “Good Reason” means
Executive’s resignation within thirty (30) days following the expiration of any Company cure period (described below) following the occurrence of one or more of the following, without Executive’s express written consent: 

(i) a material diminution of Executive’s authority, duties, or responsibilities with the Company in effect immediately prior to such
assignment; 
 (ii) a material breach of this Agreement by the Company; 

(iii) any successor to the Company (whether pursuant to any Change in Control or otherwise) does not assume this Agreement; or 

(iv) a material reduction in Executive’s base salary in effect immediately prior to such termination, unless the Company also similarly
reduces the base salaries of all other similarly-situated employees of the Company. 
 Executive will not resign for Good Reason without first providing the
Company with written notice of the acts or omissions constituting the grounds for “Good Reason” within ninety (90) days of the initial existence of the grounds for “Good Reason” and a cure period of thirty (30) days
following the date of such notice. For the avoidance of doubt, the failure of the Executive to be elected to the Board by the Company’s stockholders shall not constitute grounds for “Good Reason” hereunder. 

(f) Section 409A Limit. For purposes of this Agreement, “Section 409A Limit” will
mean two (2) times the lesser of: (i) Executive’s annualized compensation based upon the annual rate of pay paid to Executive during Executive’s taxable year preceding Executive’s taxable year of his separation from service
as determined under Treasury Regulation Section 1.409A-1(b)(9)(iii)(A)(1) and any Internal Revenue Service guidance issued with respect thereto; or (ii) the maximum amount that may be taken into
account under a qualified plan pursuant to Section 401(a)(17) of the Internal Revenue Code for the year in which Executive’s separation from service occurred. 

10. Limitation on Payments. 

(a) If Executive receives, is provided or may receive or be provided any payment or benefit that constitutes a “parachute payment”
(as defined in Section 280G(b)(2) of the Code), and the net after-tax amount of any such parachute payment is less than the net after-tax amount if the aggregate
payments and benefits to be made to Executive were three times Executive’s “base amount” (as defined in Section 280G(b)(3) of the Code), less $1.00, then the aggregate of the amounts constituting the parachute payments shall be
reduced to an amount equal to three times Executive’s base amount, less $1.00. For purposes of determining the “net after-tax amount,” the Company will cause to be taken into account all
applicable federal, state and local income and employment taxes and the excise taxes (all computed at the highest applicable marginal rate, net of the maximum reduction in federal income taxes which could be obtained from a deduction of such state
and local taxes). If a reduction pursuant to this Section 10 is to occur, (x) Executive will have no rights to any additional 

  
 -7- 

 
payments and/or benefits that are being reduced, and (y) reduction in payments and/or benefits will occur in the following order: (i) reduction of cash payments, if any, which shall
occur in reverse chronological order such that the cash payment owed on the latest date following the occurrence of the event triggering such excise tax will be the first cash payment to be reduced; (ii) cancellation of accelerated vesting of
equity awards other than stock options, if any; (iii) cancellation of accelerated vesting of stock options, if any; and (iv) reduction of other payments or benefits, if any, paid or provided to Executive, which shall occur in reverse
chronological order such that the payment or benefit owed on the latest date following the occurrence of the event triggering such excise tax will be the first benefit to be reduced. In the event that acceleration of vesting of equity awards or
stock options is to be reduced, such acceleration of vesting will be cancelled in the reverse order of the date of grant. If two or more equity awards or stock options are granted on the same date, each award or stock option will be reduced on a pro-rata basis. Notwithstanding, any excise tax imposed will be solely the responsibility of Executive. In no event shall Executive have any discretion with respect to the ordering of his payment reductions. 

(b) Unless the Company and Executive otherwise agree in writing, any determination required under this Section 10 will be made in writing
by a nationally recognized firm of independent public accountants selected by the Company, the Company’s legal counsel or such other person or entity to which the Parties mutually agree (the “Firm”), whose determination will be
conclusive and binding upon Executive and the Company for all purposes. For purposes of making the calculations required by this Section 10, the Firm may make reasonable assumptions and approximations concerning applicable taxes and may rely on
reasonable, good faith interpretations concerning the application of Sections 280G and 4999 of the Code. The Company and Executive will furnish to the Firm such information and documents as the Firm may reasonably request in order to make a
determination under this Section 10. The Company will bear all costs the Firm may reasonably incur in connection with any calculations contemplated by this Section 10. 

11. Confidential Information; Non-Solicitation. Executive agrees that Executive will continue to
be bound by the Confidential Information, Invention Assignment, Restricted Activities, and Arbitration Agreement (the “Confidential Information Agreement”) by and between Executive and the Company in accordance with its terms. In
addition, until the date one (1) year after the termination of Executive’s employment with the Company for any reason, Executive agrees to not, either directly or indirectly, solicit, induce, attempt to solicit, recruit, or encourage any
employee of the Company (or any parent or subsidiary of the Company) to leave his or her employment either for Executive or for any other entity or person. Executive represents that he (i) is familiar with the foregoing covenant not to solicit,
and (ii) is fully aware of his obligations hereunder, including, without limitation, the reasonableness of the length of time, scope and geographic coverage of this covenant. 

12. Assignment. This Agreement will be binding upon and inure to the benefit of (a) the heirs, executors and legal representatives
of Executive upon Executive’s death and (b) any successor of the Company. Any such successor of the Company will be deemed substituted for the Company under the terms of this Agreement for all purposes. For this purpose,
“successor” means any person, firm, corporation or other business entity which at any time, whether by purchase, merger or otherwise, directly or indirectly acquires all or substantially all of the assets or business of the Company.
None of the rights of Executive to receive any form of compensation payable pursuant to this Agreement may be assigned or transferred except by will or the laws of descent and distribution. Any other attempted assignment, transfer, conveyance or
other disposition of Executive’s right to compensation or other benefits will be null and void. 

  
 -8- 

 13. Notices. All notices, requests, demands and other communications called for
hereunder will be in writing and will be deemed given (i) on the date of delivery if delivered personally, (ii) one (1) day after being sent by a well established commercial overnight service, or (iii) four (4) days after being mailed

 14. Severability. In the event that any provision hereof becomes or is declared by a
court of competent jurisdiction to be illegal, unenforceable or void, this Agreement will continue in full force and effect without said provision. 

15. Arbitration. Executive agrees that any and all controversies, claims, or disputes with anyone (including the Company and any
employee, officer, director, stockholder or benefit plan of the Company in their capacity as such or otherwise) arising out of, relating to, or resulting from Executive’s service to the Company, shall be subject to arbitration in accordance
with the provisions of the Confidential Information Agreement. 
 16. Integration. This Agreement represents the entire agreement and
understanding between the parties as to the subject matter herein and supersedes all prior or contemporaneous agreements whether written or oral. This Agreement may be modified only by agreement of the parties by a written instrument executed by the
parties that is designated as an amendment to this Agreement.

 (b) Obligations. During the Employment Term, Executive will perform his duties faithfully and

 2.
At-Will Employment. The parties agree that Executive’s employment with the Company will continue to be “at-will” employment and may be terminated

3. Compensation. 
 (a)
Base Salary. During the Employment Term, the Company will pay Executive an annual salary (the “Base Salary”) of $375,000 as compensation for Executive’s services. The Base Salary will be paid periodically in accordance
with the Company’s normal payroll practices. Executive’s Base Salary will be subject to review by the Compensation Committee (the “Compensation Committee”) of the Board and adjustments to the Base Salary may be made in its
discretion. 
 (b) Bonus. During the Employment Term, Executive will be eligible to receive an annual bonus, with a target annual
bonus equal to thirty-five percent (35%) of the Base Salary, upon achievement of certain performance objectives to be determined by the Compensation Committee. The amount, terms and conditions of any annual bonus will be determined by the
Compensation Committee in its discretion and any annual bonus will be subject to the terms and conditions of the applicable Company bonus plan, as in effect from time to time. Any earned annual bonus will be paid as soon as reasonably practicable
after the Compensation Committee determines that such bonus has been earned, but in no event shall the bonus be paid after the March 15th following the end of the calendar year to which the bonus

connection with the performance of Executive’s duties hereunder. 
 (b) Subject to any applicable policy established by the Company as
in effect from time to time, the Company will reimburse Executive for expenses incurred pursuant to Section 5(a) upon Executive’s having submitted valid receipts to the Company, provided that Executive is an employee of the Company on the
date on which the expenses are incurred. Executive’s right to payment or reimbursement for expenses hereunder shall be subject to the following additional rules: (i) the amount of expenses eligible for payment or reimbursement during any
calendar year shall not affect the expenses eligible for payment or reimbursement in any other calendar year, (ii) payment or reimbursement shall be made not later than December 31 of the calendar year following the calendar year in which
the expense or payment was incurred, and (iii) the right to payment or reimbursement is not subject to liquidation or exchange for any other benefit. 

6. Severance. 
 (a)
Termination for other than Cause, Death or Disability or Resignation for Good Reason. If the Company (or any parent or subsidiary or successor of the Company) terminates Executive’s employment with the Company other than for Cause (as
defined below) and other than due to Executive’s death or Disability (as defined below), or Executive resigns with Good Reason (as 

  
 -2- 

 
defined below), then, subject to Section 8, Executive will be entitled to (i) receive severance pay at a rate equal to Executive’s Base Salary, as then in effect, for six
(6) months from the date of such termination, which will be paid in equal installments in accordance with the Company’s normal payroll practices; (ii) an amount equal to Executive’s target annual bonus for the year in which such
termination of employment occurs, multiplied by .5, payable in equal installments in accordance with the Company’s normal payroll practices over six (6) months from the date of such termination; and (iii) if Executive elects
continuation coverage pursuant to the Consolidated Omnibus Budget Reconciliation Act of 1985, as amended (“COBRA”) for Executive and his eligible dependents within the time period prescribed pursuant to COBRA, the Company will
reimburse Executive for the COBRA premiums for such coverage until the earlier of (A) a period of three (3) months from the last date of employment of Executive with the Company, or (B) the date upon which Executive ceases to be
eligible for coverage under COBRA. COBRA reimbursements will be made by the Company to Executive consistent with the Company’s normal expense reimbursement policy. However, if the Company determines in its sole discretion that it cannot provide
the foregoing COBRA benefits without potentially violating applicable law (including, without limitation, Section 2716 of the Public Health Service Act) or incurring additional taxes, the Company will in lieu thereof provide to Executive a
taxable monthly payment in an amount equal to the monthly COBRA premium that Executive would be required to pay to continue his group health coverage in effect on the date of his termination of employment (which amount will be based on the premium
for the first month of COBRA coverage) for the time period described in clause (A) in equal installments in accordance with the Company’s normal payroll practices. In addition to the amounts described above, Executive will be entitled to
receive Executive’s accrued and unpaid Base Salary through the date Executive’s employment terminates, any unreimbursed expenses due under Section 5 of above, and any vested benefits required to be paid or provided under the terms and
conditions of the Company’s benefit plans (collectively, the “Accrued Benefits”) if Executive’s employment terminates in the circumstances described in this Section 6(a). 

(b) Termination for Cause or Death or Disability; Voluntary Resignation. If Executive’s employment with the Company (or any parent
or subsidiary or successor of the Company) is terminated voluntarily by Executive without Good Reason, for Cause by the Company or due to Executive’s death or Disability, then Executive will be entitled to receive the Accrued Benefits and no
further compensation or benefits will be paid to Executive under this Agreement. 
 (c) Exclusive Remedy. In the event of a
termination of Executive’s employment with the Company (or any parent or subsidiary or successor of the Company), the provisions of this Section 6 and Section 7 below are intended to be and are exclusive and in lieu of any other
rights or remedies to which Executive or the Company may otherwise be entitled in connection with the termination of Executive’s employment under any employee compensation or benefit plan which provides benefits in the nature of severance or
continuation pay. 
 7. Termination for other than Cause, Death or Disability or Resignation for Good Reason within 24 months following a Change in
Control. If the Company (or any parent or subsidiary or successor of the Company) terminates Executive’s employment with the Company other than for Cause (as defined below) and other than due to Executive’s death or Disability (as
defined below), or Executive resigns with Good Reason (as defined below), in either case, within twenty-four (24) months following a Change of Control (as defined below) then, subject to Section 8 and in lieu of the payments set forth in
Section 6 above, Executive will be entitled to (i) receive a severance payment equal to one times 

  
 -3- 

 
(1x) the sum of (A) Executive’s annual Base Salary, as then in effect, and (B) Executive’s target annual bonus for the year in which such termination of employment occurs
(ii) an amount equal to the monthly COBRA premium that Executive would be required to pay to continue his group health coverage in effect on the date of his termination of employment for a period of nine (9) months (which amount will be
based on the premium for the first month of COBRA coverage); and (iv) accelerated vesting as to one hundred percent (100%) of Executive’s then outstanding and unvested equity and equity-based awards (with any performance-vesting awards
vesting at target levels). All amounts payable under prongs (i) and (ii) of this Section 7 will be paid in a lump sum on the first normal payroll date of the Company following the Release Deadline (as defined below) in accordance with the
Company’s normal payroll practices. In addition to the amounts described above, Executive will be entitled to receive the Accrued Benefits. 

8. Conditions to Receipt of Severance; No Duty to Mitigate. 

(a) Separation Agreement and Release of Claims. The receipt of any severance pursuant to Sections 6 or 7 will be subject to Executive
signing and not revoking a separation agreement and general release of claims in a form reasonably satisfactory to the Company (the “Release”) and provided that such Release becomes effective and irrevocable no later than sixty
(60) days following the termination date (such deadline, the “Release Deadline”). If the Release does not become effective and irrevocable by the Release Deadline, Executive will forfeit any rights to severance or benefits
under this Agreement. In no event will severance payments or benefits be paid or provided until the Release becomes effective and irrevocable. Subject to Section 8(b), any cash severance pay to which Executive is entitled pursuant to
Section 6 or 7 (other than the Accrued Obligations) will be paid, or will begin to be paid, on the first normal payroll date of the Company following the Release Deadline, with such payment to include all amounts that would have been paid prior
to such date but for this Section 8(a). 
 (b) Section 409A.  

(i) Notwithstanding anything to the contrary in this Agreement, no severance pay or benefits to be paid or provided to Executive, if any,
pursuant to this Agreement that, when considered together with any other payments or benefits, would be considered deferred compensation under Code Section 409A and the final regulations and any guidance promulgated thereunder (collectively,
“Section 409A”) (together, the “Deferred Payments”) will be paid or otherwise provided until Executive has incurred a “separation from service” within the meaning of Section 409A.

 (ii) Notwithstanding anything to the contrary in this Agreement, if Executive is a “specified employee” within the meaning of
Section 409A at the time of Executive’s termination (other than due to death), then the Deferred Payments that are payable within the first six (6) months following Executive’s separation from service, will become payable on the
first payroll date that occurs on or after the date six (6) months and one (1) day following the date of Executive’s separation from service. All subsequent Deferred Payments, if any, will be payable in accordance with the payment
schedule applicable to each payment or benefit. Notwithstanding anything herein to the contrary, if Executive dies following Executive’s separation from service, but prior to the six (6) month anniversary of the separation from service,
then any payments delayed in accordance with this paragraph will be payable in a lump sum as soon as administratively practicable after the date of Executive’s death and all other Deferred Payments will be payable in accordance with the payment
schedule applicable to each payment or benefit. Each payment and benefit payable under this Agreement is intended to constitute a separate payment for purposes of Section 1.409A-2(b)(2) of the Treasury
Regulations. 
  

  
 -4- 

 (iii) Any amounts paid under this Agreement that satisfies the requirements of the
“short-term deferral” rule set forth in Section 1.409A-1(b)(4) of the Treasury Regulations will not constitute Deferred Payments for purposes of clause (i) above. 

(iv) Any amount paid under this Agreement that qualifies as a payment made as a result of an involuntary separation from service pursuant to Section 1.409A-1(b)(9)(iii) of the Treasury Regulations that does not exceed the Section 409A Limit (as defined below) will not constitute Deferred Payments for purposes of clause (i) above. 

(v) All payments under this Agreement are intended to be exempt from, or comply with, the requirements of Section 409A so that none of
the payments and benefits provided hereunder will be subject to the additional tax imposed under Section 409A, and any ambiguities herein will be interpreted to so comply. The Company and 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 Executive under Section 409A. In
no event will the Company, any of its subsidiaries or affiliates be liable to Executive by reason of any acceleration of income or any additional tax (including any interest and penalties) asserted with respect to the failure of any payments or
benefits provided under this Agreement to satisfy the applicable requirements of Section 409A. 
 (c) Confidential Information
Agreement. Executive’s continuing receipt of any payments or benefits under Section 6 or 7 will be subject to Executive continuing to comply with the terms of Confidential Information Agreement (as defined in Section 11). In the
event Executive breaches the provisions of the Confidential Information Agreement, then all payments and benefits to which Executive may otherwise be entitled pursuant to Sections 6 or 7 will immediately cease. 

(d) No Duty to Mitigate. Executive will not be required to mitigate the amount of any payment contemplated by this Agreement, nor will
any earnings that Executive may receive from any other source reduce any such payment. 
 9. Definitions. 

(a) Cause. For purposes of this Agreement, “Cause” is defined, as determined by the Company in its reasonable judgment,
as (i) breach of this Agreement or the Confidential Information Agreement by Executive; (ii) intentional and continued nonperformance or misperformance of Executive’s duties or refusal to abide by or comply with the reasonable
directives of the CEO or the Board, or the Company’s policies and procedures, which, if reasonably susceptible to cure (as determined by the Company), is not cured within fifteen (15) days following Executive’s receipt of written
notice from the Company describing in reasonable detail the nature of the nonperformance, misperformance or refusal, as applicable; (iii) Executive’s gross negligence in the performance of his material duties under this Agreement;
(iv) Executive’s fraud or willful misconduct with respect to the business or affairs of the Company; (v) Executive’s conviction of, or a plea of nolo contendere to, a felony or other crime involving moral turpitude; or
(vi) the commission of any act in direct or indirect competition with or materially detrimental to the best interests of Company. 

  
 -5- 

 (b) Change of Control. For purposes of this Agreement, “Change of
Control” is defined as: 
 (i) the acquisition of the Company by another entity by means of any transaction or series of related
transactions (including, without limitation, any reorganization, merger or consolidation or stock transfer, but excluding any such transaction effected primarily for the purpose of changing the domicile of the Company), unless the Company’s
stockholders of record immediately prior to such transaction or series of related transactions hold, immediately after such transaction or series of related transactions, at least fifty percent (50%) of the voting power of the surviving or acquiring
entity (provided that the sale by the Company of its securities for the primary purpose of raising additional funds shall not constitute a Change of Control hereunder); or 

(ii) a sale, license or other disposition of all or substantially all of the assets, intellectual property or technology of the Company. 

Notwithstanding the foregoing provisions of this definition, a transaction will not be deemed a Change of Control unless the transaction
qualifies as a “change in control event” within the meaning of Section 409A. 
 (c) Code. For purposes of this
Agreement, “Code” means the Internal Revenue Code of 1986, as amended. 
 (d) Disability. For purposes of this
Agreement, “Disability” means that Executive has been unable to perform Executive’s Company duties as the result of Executive’s incapacity due to physical or mental illness for at least
twenty-six (26) weeks after the commencement of such incapacity or for one-hundred and eighty (180) days in any consecutive twelve (12) month period,
which incapacity is determined by a physician selected by the Company or its insurers and acceptable to Executive or Executive’s legal representative (such agreement as to acceptability not to be unreasonably withheld). 

(e) Good Reason. For purposes of this Agreement, “Good Reason” means Executive’s resignation within thirty
(30) days following the expiration of any Company cure period (described below) following the occurrence of one or more of the following, without Executive’s consent: 

(i) a material diminution of Executive’s authority, duties, or responsibilities with the Company in effect immediately prior to such
assignment; 
 (ii) a material breach of this Agreement by the Company; or 

(iii) a material reduction in Executive’s base salary in effect immediately prior to such termination, unless the Company also similarly
reduces the base salaries of all other similarly-situated employees of the Company. 

  
 -6- 

 Executive will not resign for Good Reason without first providing the Company with written notice of the
acts or omissions constituting the grounds for “Good Reason” within ninety (90) days of the initial existence of the grounds for “Good Reason” and a cure period of thirty (30) days following the date of such notice.

 (f) Section 409A Limit. For purposes of this Agreement, “Section 409A Limit”
will mean two (2) times the lesser of: (i) Executive’s annualized compensation based upon the annual rate of pay paid to Executive during Executive’s taxable year preceding Executive’s taxable year of his separation from
service as determined under Treasury Regulation Section 1.409A-1(b)(9)(iii)(A)(1) and any Internal Revenue Service guidance issued with respect thereto; or (ii) the maximum amount that may be taken
into account under a qualified plan pursuant to Section 401(a)(17) of the Internal Revenue Code for the year in which Executive’s separation from service occurred. 

10. Limitation on Payments. 

(a) If Executive receives, is provided or may receive or be provided any payment or benefit that constitutes a “parachute payment”
(as defined in Section 280G(b)(2) of the Code), and the net after-tax amount of any such parachute payment is less than the net after-tax amount if the aggregate
payments and benefits to be made to Executive were three times Executive’s “base amount” (as defined in Section 280G(b)(3) of the Code), less $1.00, then the aggregate of the amounts constituting the parachute payments shall be
reduced to an amount equal to three times Executive’s base amount, less $1.00. For purposes of determining the “net after-tax amount,” the Company will cause to be taken into account all
applicable federal, state and local income and employment taxes and the excise taxes (all computed at the highest applicable marginal rate, net of the maximum reduction in federal income taxes which could be obtained from a deduction of such state
and local taxes). If a reduction pursuant to this Section 10 is to occur, (x) Executive will have no rights to any additional payments and/or benefits that are being reduced, and (y) reduction in payments and/or benefits will occur in
the following order: (i) reduction of cash payments, if any, which shall occur in reverse chronological order such that the cash payment owed on the latest date following the occurrence of the event triggering such excise tax will be the first
cash payment to be reduced; (ii) cancellation of accelerated vesting of equity awards other than stock options, if any; (iii) cancellation of accelerated vesting of stock options, if any; and (iv) reduction of other payments or
benefits, if any, paid or provided to Executive, which shall occur in reverse chronological order such that the payment or benefit owed on the latest date following the occurrence of the event triggering such excise tax will be the first benefit to
be reduced. In the event that acceleration of vesting of equity awards or stock options is to be reduced, such acceleration of vesting will be cancelled in the reverse order of the date of grant. If two or more equity awards or stock options are
granted on the same date, each award or stock option will be reduced on a pro-rata basis. Notwithstanding, any excise tax imposed will be solely the responsibility of Executive. In no event shall Executive
have any discretion with respect to the ordering of his payment reductions. 
 (b) Unless the Company and Executive otherwise agree in
writing, any determination required under this Section 10 will be made in writing by a nationally recognized firm of independent public accountants selected by the Company, the Company’s legal counsel or such other person or entity to
which the Parties mutually agree (the “Firm”), whose determination will be conclusive and binding upon Executive and the Company for all purposes. For purposes of making the calculations required by this Section 10, the Firm
may make reasonable assumptions and 

  
 -7- 

 
approximations concerning applicable taxes and may rely on reasonable, good faith interpretations concerning the application of Sections 280G and 4999 of the Code. The Company and Executive will
furnish to the Firm such information and documents as the Firm may reasonably request in order to make a determination under this Section 10. The Company will bear all costs the Firm may reasonably incur in connection with any calculations
contemplated by this Section 10. 
 11. Confidential Information. Executive agrees that Executive will continue to be bound by
the Confidential Information, Invention Assignment, Restricted Activities, and Arbitration Agreement (the “Confidential Information Agreement”) by and between Executive and the Company in accordance with its terms. 

12. Assignment. This Agreement will be binding upon and inure to the benefit of (a) the heirs, executors and legal representatives
of Executive upon Executive’s death and (b) any successor of the Company. Any such successor of the Company will be deemed substituted for the Company under the terms of this Agreement for all purposes. For this purpose,
“successor” means any person, firm, corporation or other business entity which at any time, whether by purchase, merger or otherwise, directly or indirectly acquires all or substantially all of the assets or business of the Company.
None of the rights of Executive to receive any form of compensation payable pursuant to this Agreement may be assigned or transferred except by will or the laws of descent and distribution. Any other attempted assignment, transfer, conveyance or
other disposition of Executive’s right to compensation or other benefits will be null and void. 
 13. Notices. All notices,
requests, demands and other communications called for hereunder will be in writing and will be deemed given (i) on the date of delivery if delivered personally, (ii) one (1) day after being sent by a well established commercial overnight
service, or (iii) four (4) days after being mailed by registered or certified mail, return receipt requested, prepaid and addressed to the parties or their successors at the following addresses, or at such other addresses as the parties may
later designate in writing: 
 If to the Company: 

LogicBio Therapeutics, Inc. 
 700
Main Street 
 Cambridge, Massachusetts 02139 

If to Executive:

residential address known by the Company. 
 14. Severability. In the event that any provision hereof becomes or is declared by a
court of competent jurisdiction to be illegal, unenforceable or void, this Agreement will continue in full force and effect without said provision. 

15. Arbitration. Executive agrees that any and all controversies, claims, or disputes with anyone (including the Company and any
employee, officer, director, stockholder or benefit plan of the Company in their capacity as such or otherwise) arising out of, relating to, or resulting from Executive’s service to the Company, shall be subject to arbitration in accordance
with the provisions of the Confidential Information Agreement. 

  
 -8- 

 16. Integration. This Agreement represents the entire agreement and understanding
between the parties as to the subject matter herein and supersedes all prior or contemporaneous agreements whether written or oral. This Agreement may be modified only by agreement of the parties by a written instrument executed by the parties that
is designated as an amendment to this Agreement. 
 17. Waiver of Breach. The waiver of a breach of any term or provision of this
Agreement, which must be in writing, will not operate as or be construed to be a waiver of any other previous or subsequent breach of this Agreement. 

18. Headings. All captions and section headings used in this Agreement are for convenient reference only and do not form a part of this
Agreement. 
 19. Tax Withholding. All payments made pursuant to this Agreement will be subject to withholding of applicable taxes and
other legally required amounts. 
 20. Governing Law. This Agreement will be governed by the laws of the Commonwealth of Massachusetts
without regard to any conflict of laws principles that would result in the application of the laws of any other jurisdiction. Executive agrees to submit to the exclusive jurisdiction of the courts of or in the Commonwealth of Massachusetts in
connection with any dispute arising out of this Agreement. 
 21. Acknowledgment. Executive acknowledges that he has had the
opportunity to discuss this matter with and obtain advice from his private attorney, has had sufficient time to, and has carefully read and fully understands all the provisions of this Agreement, and is knowingly and voluntarily entering into this
Agreement. 
 22. Counterparts. This Agreement may be executed in counterparts, and each counterpart will have the same force and
effect as an original and will constitute an effective, binding agreement on the part of each of the undersigned.
