	II.	 AGREEMENT 

1. Grant of Restricted Stock. The Company hereby grants to the person named in the Notice of Grant of Restricted Stock in Part I of this
Agreement (“Participant”) under the Plan for services performed and to be performed by Participant for the Company and as a separate incentive in connection with his or her services and not in lieu of any salary or other compensation for
his or her services, the number of Shares set forth in the Notice of Grant of Restricted Stock, subject to all of the terms and conditions in this Agreement and the Plan, which is incorporated herein by reference. Subject to Section 18(c) of
the Plan, in the event of a conflict between the terms and conditions of the Plan and this Agreement, the terms and conditions of the Plan shall prevail. 

 2. Participant’s Representations. In the event the Shares have not been
registered under the Securities Act of 1933, as amended, at the time this Restricted Stock Award is granted, Participant shall, if required by the Company, concurrently with the grant of this Restricted Stock Award, deliver to the Company his or her
Investment Representation Statement in the form attached hereto as Exhibit A. 
 3. Lock-Up
Period. Participant hereby agrees that Participant shall not offer, pledge, sell, contract to sell, sell any option or contract to purchase, purchase any option or contract to sell, grant any option, right or warrant to purchase, lend, or
otherwise transfer or dispose of, directly or indirectly, any Common Stock (or other securities) of the Company or enter into any swap, hedging or other arrangement that transfers to another, in whole or in part, any of the economic consequences of
ownership of any Common Stock (or other securities) of the Company held by Participant (other than those included in the registration) for a period specified by the representative of the underwriters of Common Stock (or other securities) of the
Company not to exceed one hundred and eighty (180) days following the effective date of any registration statement of the Company filed under the Securities Act (or such other period as may be requested by the Company or the underwriters to
accommodate regulatory restrictions on (i) the publication or other distribution of research reports and (ii) analyst recommendations and opinions, including, but not limited to, the restrictions contained in NASD Rule 2711(f)(4) or NYSE
Rule 472(f)(4), or any successor provisions or amendments thereto). 
 Participant agrees to execute and deliver such other agreements as
may be reasonably requested by the Company or the underwriter which are consistent with the foregoing or which are necessary to give further effect thereto. In addition, if requested by the Company or the representative of the underwriters of Common
Stock (or other securities) of the Company, Participant shall provide, within ten (10) days of such request, such information as may be required by the Company or such representative in connection with the completion of any public offering of
the Company’s securities pursuant to a registration statement filed under the Securities Act. The obligations described in this Section 3 shall not apply to a registration relating solely to employee benefit plans on Form S-1 or Form S-8 or similar forms that may be promulgated in the future, or a registration relating solely to a Commission Rule 145 transaction on Form S-4 or similar forms that may be promulgated in the future. The Company may impose stop-transfer instructions with respect to the shares of Common Stock (or other securities) subject to the foregoing restriction
until the end of said one hundred and eighty (180) day (or other) period. Participant agrees that any transferee of the Restricted Stock Award or Shares acquired pursuant to the Restricted Stock Award shall be bound by this Section 3. 

4. Non-Transferability of Restricted Stock. This Restricted Stock Award may not be transferred
in any manner otherwise than by will or by the laws of descent or distribution and may be exercised during the lifetime of Participant only by Participant. The terms of the Plan and this Agreement shall be binding upon the executors, administrators,
heirs, successors and assigns of Participant. 
 5. Tax Consequences. Participant has reviewed with Participant’s own tax
advisors the federal, state, local and foreign tax consequences of this investment and the transactions contemplated by this Agreement. Participant is relying solely on such advisors and not on any statements or representations of the Company or any
of its agents. Participant understands that Participant (and not the Company) shall be responsible for Participant’s own tax liability that may arise as a result of the transactions contemplated by this Agreement. Participant understands that

  
 -2- 

 
Section 83 of the Internal Revenue Code of 1986, as amended (the “Code”), taxes as ordinary income the difference between the purchase price, if any, for the Shares and the Fair
Market Value of the Shares as of each vesting date. Participant understands that Participant may elect to be taxed at the time the Shares are granted rather than when such Shares vest by filing an election under Section 83(b) of the Code (the
“83(b) Election”) with the IRS within thirty (30) days from the date of grant of the Restricted Stock Award. The form for making this election is attached as Exhibit B-3 hereto. 

PARTICIPANT ACKNOWLEDGES THAT IT IS PARTICIPANT’S SOLE RESPONSIBILITY AND NOT THE COMPANY’S TO FILE TIMELY THE 83(b) ELECTION, EVEN
IF PARTICIPANT REQUESTS THE COMPANY OR ITS REPRESENTATIVES TO MAKE THIS FILING ON PARTICIPANT’S BEHALF. 
 6. Tax Withholding.
Pursuant to such procedures as the Administrator may specify from time to time, the Company shall withhold the minimum amount required to be withheld for the payment of income, employment and other taxes which the Company determines must be withheld
(the “Withholding Taxes”) with respect to the filing of an 83(b) Election, or, if an 83(b) Election is not filed or not timely filed, upon each vesting date, by, in the Administrator’s discretion: (i) withholding otherwise
deliverable Shares having a Fair Market Value equal to the amount of such Withholding Taxes, (ii) withholding the amount of such Withholding Taxes from Participant’s paycheck(s), (iii) requiring Participant to make appropriate arrangements
with the Company (or the Parent or Subsidiary employing or retaining Participant) for the satisfaction of all Withholding Taxes, or (iv) a combination of the foregoing. The Company shall not retain fractional Shares to satisfy any portion of
the Withholding Taxes. Accordingly, if any withholding is done through the withholding of Shares, Participant shall pay to the Company an amount in cash sufficient to satisfy the remaining Withholding Taxes due and payable as a result of the Company
not retaining fractional Shares. Should the Company be unable to procure such cash amounts from Participant, Participant agrees and acknowledges that Participant is giving the Company permission to withhold from Participant’s paycheck(s) an
amount equal to the remaining Withholding Taxes due and payable as a result of the Company not retaining fractional Shares. Participant acknowledges and agrees that the Company may refuse to honor the exercise and refuse to deliver the Shares if
such withholding amounts are not delivered at the time they are due. 
 7. No Guarantee of Continued Service. PARTICIPANT ACKNOWLEDGES
AND AGREES THAT THE VESTING OF THE SHARES OF RESTRICTED STOCK PURSUANT TO THE VESTING SCHEDULE HEREOF IS EARNED ONLY BY CONTINUING AS A SERVICE PROVIDER AT THE WILL OF THE COMPANY (OR THE PARENT OR SUBSIDIARY EMPLOYING OR RETAINING PARTICIPANT) AND
NOT THROUGH THE ACT OF BEING HIRED, BEING GRANTED THIS RESTRICTED STOCK AWARD OR ACQUIRING SHARES HEREUNDER. PARTICIPANT FURTHER ACKNOWLEDGES AND AGREES THAT THIS AGREEMENT, THE TRANSACTIONS CONTEMPLATED HEREUNDER AND THE VESTING SCHEDULE SET FORTH
HEREIN DO NOT CONSTITUTE AN EXPRESS OR IMPLIED PROMISE OF CONTINUED ENGAGEMENT AS A SERVICE PROVIDER FOR THE VESTING PERIOD, FOR ANY PERIOD, OR AT ALL, AND SHALL NOT INTERFERE IN ANY WAY WITH PARTICIPANT’S RIGHT OR THE RIGHT OF THE COMPANY (OR
THE PARENT OR SUBSIDIARY EMPLOYING OR RETAINING PARTICIPANT) TO TERMINATE PARTICIPANT’S RELATIONSHIP AS A SERVICE PROVIDER AT ANY TIME, WITH OR WITHOUT CAUSE. 

  
 -3- 

 8. Forfeiture Upon Termination as a Service Provider. Notwithstanding any contrary
provision of this Agreement or the Notice of Grant of Restricted Stock, if Participant terminates service as a Service Provider for any or no reason prior to vesting, the then Unvested Shares of Restricted Stock awarded by this Agreement will
thereupon be forfeited and automatically transferred to and reacquired by the Company at no cost to the Company upon the date of such termination and Participant will have no further rights thereunder. Participant hereby appoints the Escrow Agent
with full power of substitution, as Participant’s true and lawful attorney-in-fact with irrevocable power and authority in the name and on behalf of Participant to
take any action and execute all documents and instruments, including, without limitation, stock powers which may be necessary to transfer the certificate or certificates evidencing such Unvested Shares of Restricted Stock to the Company upon such
termination of service. 
 9. Restriction on Transfer. Except for the escrow described in Section 10 or transfer of the Shares to
the Company or its assignees contemplated by this Agreement, none of the Shares or any beneficial interest therein shall be transferred, encumbered or otherwise disposed of in any way until such Shares shall have vested in accordance with the
provisions of this Agreement, other than by will or the laws of descent and distribution. Any distribution or delivery to be made to Participant under this Agreement shall, if Participant is then deceased, be made to Participant’s designated
beneficiary, or if no beneficiary survives Participant, to the administrator or executor of Participant’s estate. Any such transferee must furnish the Company with (a) written notice of his or her status as transferee, and
(b) evidence satisfactory to the Company to establish the validity of the transfer and compliance with any laws or regulations pertaining to said transfer. 

10. Escrow of Shares. 
 (a)
All Shares of Restricted Stock will, upon execution of this Agreement, be delivered and deposited with an escrow holder designated by the Company (the “Escrow Holder”), together with the Assignment Separate from Certificate (the
“Stock Assignment”) duly endorsed in blank, attached hereto as Exhibit B-1. The Shares of Restricted Stock and the Stock Assignment will be held by the Escrow Holder, pursuant to the Joint
Escrow Instructions of the Company and Participant attached as Exhibit B-2 hereto. 
 (b) The
Escrow Holder shall not be liable for any act it may do or omit to do with respect to holding the Shares of Restricted Stock in escrow and while acting in good faith and in the exercise of its judgment. 

(c) Upon Participant’s termination as a Service Provider for any reason, the Escrow Holder, upon receipt of written notice of such
termination, will take all steps necessary to accomplish the transfer of the Unvested Shares of Restricted Stock to the Company. Participant hereby appoints the Escrow Holder with full power of substitution, as Participant’s true and lawful attorney-in-fact with irrevocable power and authority in the name and on behalf of Participant to take any action and execute all documents and instruments, including, without
limitation, stock powers which may be necessary to transfer the certificate or certificates evidencing such Unvested Shares of Restricted Stock to the Company upon such termination. 

  
 -4- 

 (d) The Escrow Holder will take all steps necessary to accomplish the transfer of Shares of
Restricted Stock to Participant after they vest following Participant’s request that the Escrow Holder do so. 
 (e) Subject to the
terms hereof, Participant shall have all the rights of a shareholder with respect to such Shares while they are held in escrow, including without limitation, the right to vote the Shares and receive any cash dividends declared thereon. 

(f) In the event of any merger, reorganization, consolidation, recapitalization, separation, liquidation, stock dividend, split-up, share combination, or other change in the corporate structure of the Company affecting the Common Stock, the Shares shall be increased, reduced or otherwise changed, and by virtue of any such change
Participant shall in his or her capacity as owner of the Unvested Shares of Restricted Stock that have been awarded to him or her be entitled to new or additional or different shares of stock, cash or securities (other than rights or warrants to
purchase securities); such new or additional or different shares, cash or securities shall thereupon be considered to be “Unvested Shares of Restricted Stock” and shall be subject to all of the conditions and restrictions which were
applicable to the Unvested Shares of Restricted Stock pursuant to this Agreement. If Participant receives rights or warrants with respect to any Unvested Shares of Restricted Stock, such rights or warrants may be held or exercised by Participant,
provided that until such exercise any such rights or warrants and after such exercise any shares or other securities acquired by the exercise of such rights or warrants shall be considered to be Unvested Shares of Restricted Stock and shall be
subject to all of the conditions and restrictions which were applicable to the Unvested Shares of Restricted Stock pursuant to this Agreement. The Administrator in its absolute discretion at any time may accelerate the vesting of all or any portion
of such new or additional shares of stock, cash or securities, rights or warrants to purchase securities or shares or other securities acquired by the exercise of such rights or warrants. 

11. Company’s Right of First Refusal. Subject to Section 9, before any vested Shares held by Participant or any transferee
(either being sometimes referred to herein as the “Holder”) may be sold or otherwise transferred (including transfer by gift or operation of law), the Company or its assignee(s) shall have a right of first refusal to purchase the Shares on
the terms and conditions set forth in this Section 11 (the “Right of First Refusal”). 
 (a) Notice of Proposed
Transfer. The Holder of the Shares shall deliver to the Company a written notice (the “Notice”) stating: (i) the Holder’s bona fide intention to sell or otherwise transfer such Shares; (ii) the name of each proposed
purchaser or other transferee (“Proposed Transferee”); (iii) the number of Shares to be transferred to each Proposed Transferee; and (iv) the bona fide cash price or other consideration for which the Holder proposes to transfer the
Shares (the “Offered Price”), and the Holder shall offer the Shares at the Offered Price to the Company or its assignee(s). 
 (b)
Exercise of Right of First Refusal. At any time within thirty (30) days after receipt of the Notice, the Company and/or its assignee(s) may, by giving written notice to the Holder, elect to purchase all, but not less than all, of the
Shares proposed to be transferred to any one or more of the Proposed Transferees, at the purchase price determined in accordance with subsection (c) below. 

  
 -5- 

 (c) Purchase Price. The purchase price (“Right of First Refusal Price”) for
the Shares purchased by the Company or its assignee(s) under this Section 11 shall be the Offered Price. If the Offered Price includes consideration other than cash, the cash equivalent value of the
non-cash consideration shall be determined by the Board in good faith. 
 (d) Payment. Payment
of the Right of First Refusal Price shall be made, at the option of the Company or its assignee(s), in cash (by check), by cancellation of all or a portion of any outstanding indebtedness of the Holder to the Company (or, in the case of repurchase
by an assignee, to the assignee), or by any combination thereof within thirty (30) days after receipt of the Notice or in the manner and at the times set forth in the Notice. 

(e) Holder’s Right to Transfer. If all of the Shares proposed in the Notice to be transferred to a given Proposed Transferee are
not purchased by the Company and/or its assignee(s) as provided in this Section 11, then the Holder may sell or otherwise transfer such Shares to that Proposed Transferee at the Offered Price or at a higher price, provided that such sale or
other transfer is consummated within one hundred and twenty (120) days after the date of the Notice, that any such sale or other transfer is effected in accordance with any applicable securities laws and that the Proposed Transferee agrees in
writing that the provisions of this Section 11 shall continue to apply to the Shares in the hands of such Proposed Transferee. If the Shares described in the Notice are not transferred to the Proposed Transferee within such period, a new Notice
shall be given to the Company, and the Company and/or its assignees shall again be offered the Right of First Refusal before any Shares held by the Holder may be sold or otherwise transferred. 

(f) Exception for Certain Family Transfers. Anything to the contrary contained in this Section 11 notwithstanding, the transfer of
any or all of the Shares during Participant’s lifetime or on Participant’s death by will or intestacy to Participant’s immediate family or a trust for the benefit of Participant’s immediate family shall be exempt from the
provisions of this Section 11. “Immediate Family” as used herein shall mean spouse, lineal descendant or antecedent, father, mother, brother or sister. In such case, the transferee or other recipient shall receive and hold the Shares
so transferred subject to the provisions of this Agreement, including but not limited to this Section 11 and Section 8, and there shall be no further transfer of such Shares except in accordance with the terms of this Section 11. 

(g) Termination of Right of First Refusal. The Right of First Refusal shall terminate as to any Shares upon the earlier of (i) the
first sale of Common Stock of the Company to the general public, or (ii) a Change in Control in which the successor corporation has equity securities that are publicly traded. 

12. Restrictive Legends and Stop-Transfer Orders. 

(a) Legends. Participant understands and agrees that the Company shall cause the legends set forth below or legends substantially
equivalent thereto, to be placed upon any certificate(s) evidencing ownership of the Shares together with any other legends that may be required by the Company or by state or federal securities laws:

 THE SECURITIES REPRESENTED HEREBY HAVE NOT BEEN REGISTERED UNDER THE SECURITIES ACT OF 1933
(THE “ACT”) AND MAY NOT BE OFFERED, SOLD OR OTHERWISE TRANSFERRED, PLEDGED OR HYPOTHECATED UNLESS AND UNTIL REGISTERED UNDER THE ACT OR, IN THE OPINION OF COUNSEL SATISFACTORY TO THE ISSUER OF THESE SECURITIES, SUCH OFFER, SALE OR
TRANSFER, PLEDGE OR HYPOTHECATION IS IN COMPLIANCE THEREWITH. 
 THE SHARES REPRESENTED BY THIS CERTIFICATE ARE SUBJECT TO CERTAIN
RESTRICTIONS ON TRANSFER, A RIGHT OF FIRST REFUSAL AND FORFEITURE RIGHTS IN FAVOR OF THE ISSUER OR ITS ASSIGNEE(S) AS SET FORTH IN THE RESTRICTED STOCK AGREEMENT BETWEEN THE ISSUER AND THE ORIGINAL HOLDER OF THESE SHARES, A COPY OF WHICH MAY BE
OBTAINED AT THE PRINCIPAL OFFICE OF THE ISSUER. SUCH TRANSFER RESTRICTIONS, RIGHT OF FIRST REFUSAL AND FORFEITURE RIGHTS IN FAVOR OF THE ISSUER OR ITS ASSIGNEE(S) ARE BINDING ON TRANSFEREES OF THESE SHARES. 

THE SHARES REPRESENTED BY THIS CERTIFICATE ARE SUBJECT TO RESTRICTIONS ON TRANSFER FOR A PERIOD OF TIME FOLLOWING THE EFFECTIVE DATE OF THE
UNDERWRITTEN PUBLIC OFFERING OF THE COMPANY’S SECURITIES SET FORTH IN AN AGREEMENT BETWEEN THE ISSUER AND THE ORIGINAL HOLDER OF THESE SHARES AND MAY NOT BE SOLD OR OTHERWISE DISPOSED OF BY THE HOLDER PRIOR TO THE 

EXPIRATION OF SUCH PERIOD WITHOUT THE CONSENT OF THE COMPANY OR THE MANAGING UNDERWRITER. 

(b) Stop-Transfer Notices. Participant agrees that, in order to ensure compliance with the restrictions referred to herein, the Company
may issue appropriate “stop transfer” instructions to its transfer agent, if any, and that, if the Company transfers its own securities, it may make appropriate notations to the same effect in its own records. 

(c) Refusal to Transfer. The Company shall not be required (i) to transfer on its books any Shares that have been sold or otherwise
transferred in violation of any of the provisions of this Agreement or (ii) to treat as owner of such Shares or to accord the right to vote or pay dividends to any purchaser or other transferee to whom such Shares shall have been so
transferred. 
 13. Address for Notices. Any notice to be given to the Company under the terms of this Award Agreement will be
addressed to the Company at                             , or at such other address as the Company may
hereafter designate in writing. 
 Any notice to the Escrow Holder shall be sent to the Company’s address with a copy to the other party
not sending the notice. 
 14. Electronic Delivery. The Company may, in its sole discretion, decide to deliver any documents related
to the Shares of Restricted Stock awarded under the Plan or future Restricted Stock that may be awarded under the Plan by electronic means or request Participant’s consent to participate in the Plan by electronic means. Participant hereby
consents to receive such documents by electronic delivery and agrees to participate in the Plan through any on-line or electronic system established and maintained by the Company or another third party
designated by the Company. 

  
 -7- 

 15. No Waiver. Either party’s failure to enforce any provision or provisions of
this Agreement shall not in any way be construed as a waiver of any such provision or provisions, nor prevent that party from thereafter enforcing each and every other provision of this Agreement. The rights granted both parties herein are
cumulative and shall not constitute a waiver of either party’s right to assert all other legal remedies available to it under the circumstances. 

16. Successors and Assigns. The Company may assign any of its rights under this Agreement to single or multiple assignees, and this
Agreement shall inure to the benefit of the successors and assigns of the Company. Subject to the restrictions on transfer herein set forth, this Agreement shall be binding upon Participant and his or her heirs, executors, administrators, successors
and assigns. The rights and obligations of Participant under this Agreement may only be assigned with the prior written consent of the Company. 

17. Interpretation. The Administrator will have the power to interpret the Plan and this Agreement and to adopt such rules for the
administration, interpretation and application of the Plan as are consistent therewith and to interpret or revoke any such rules (including, but not limited to, the determination of whether or not any Shares of Restricted Stock have vested). All
actions taken and all interpretations and determinations made by the Administrator in good faith will be final and binding upon Participant, the Company and all other interested persons. Neither the Administrator nor any person acting on behalf of
the Administrator will be personally liable for any action, determination or interpretation made in good faith with respect to the Plan or this Agreement. 

18. Additional Documents. Participant agrees upon request to execute any further documents or instruments necessary or desirable to
carry out the purposes or intent of this Agreement. 
 19. Governing Law; Severability. This Agreement is governed by the internal
substantive laws, but not the choice of law rules, of California. 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 shall continue in full force
and effect. 
 20. Entire Agreement. The Plan is incorporated herein by reference. The Plan and this Agreement (including the exhibits
referenced herein) constitute the entire agreement of the parties with respect to the subject matter hereof and supersede in their entirety all prior undertakings and agreements of the Company and Participant with respect to the subject matter
hereof, and may not be modified adversely to the Participant’s interest except by means of a writing signed by the Company and Participant. 

Participant acknowledges receipt of a copy of the Plan and represents that he or she is familiar with the terms and provisions thereof, and
hereby accepts this Agreement subject to all of the terms and provisions thereof. Participant has reviewed the Plan and this Agreement in their entirety, has had an opportunity to obtain the advice of counsel prior to executing this Agreement

 Exhibit 10.8 

LOGICBIO THERAPEUTICS, INC. 

2018 EQUITY INCENTIVE PLAN 

1. DEFINED TERMS 

Exhibit A, which is incorporated by reference, defines certain terms used in the Plan and sets forth operational rules related to those
terms. 
 2. PURPOSE 

The Plan is intended to advance the interests of the Company by providing for the grant to Participants of Stock and Stock-based Awards. The
purposes of the Plan are to attract, retain, and reward key Employees and Directors of, and consultants and advisors to, the Company and its subsidiaries, to incentivize them to generate stockholder value, to enable them to participate in the growth
of the Company and to align their interests with the interests of the Company’s stockholders.  

3. ADMINISTRATION 
 The
Plan will be administered by the Administrator. The Administrator has discretionary authority, subject only to the express provisions of the Plan, to administer and interpret the Plan and any Award; to determine eligibility for and grant Awards; to
determine the exercise price, base value from which appreciation is measured, or purchase price, if any, applicable to any Award; to determine, modify or waive the terms and conditions of any Award; to determine the form of settlement of Awards
(whether in cash, shares of Stock, other Awards, or other property); to prescribe forms, rules and procedures relating to the Plan and Awards; and to otherwise do all things necessary or desirable to carry out the purposes of the Plan or any Award.
Determinations of the Administrator made with respect to the Plan or any Award are conclusive and bind all persons. 
 4. LIMITS
ON AWARDS UNDER THE PLAN 
 (a) Number of
Shares. Subject to adjustment as provided in Section 7(b), the number of shares of Stock that may be issued in satisfaction of Awards under the Plan is 1,183,214 shares of Stock (the “Initial Share Pool”). The
Initial Share Pool will automatically increase on January 1st of each year from 2019 until 2028, by the lesser of (A) four percent of the number of shares of Stock outstanding as of the close
of business on the immediately preceding December 31st; and (B) the number of shares of Stock determined by the Board on or prior to such date for such year (the Initial Share Pool, as it may
be so increased, the “Share Pool”). Up to 1,183,214 of the shares of Stock from the Share Pool may be issued in satisfaction of ISOs, but nothing in this Section 4(a) will be construed as requiring that any, or any fixed number
of, ISOs be granted under the Plan. For purposes of this Section 4(a), shares of Stock will not be treated as issued under the Plan, and will not reduce the Share Pool, unless and until, and to the extent, the shares are actually issued to a
Participant. Without limiting the generality of the foregoing, shares of Stock withheld by the Company in payment of the exercise price or purchase price of an Award or in satisfaction of tax withholding requirements with respect to an Award and
shares of Stock underlying any portion of an Award that is settled or that expires, becomes unexercisable, terminates or is forfeited to or repurchased by the Company, in each case, without the issuance (or retention (in the case of Restricted
Stock)) of Stock, will not be treated as issued in satisfaction of Awards under the Plan and will not reduce the Share Pool. The limits set forth in this Section 4(a) will be construed to comply with the applicable requirements of
Section 422. 

 (b) Substitute Awards. The Administrator may grant
Substitute Awards under the Plan. To the extent consistent with the requirements of Section 422 and the regulations thereunder and other applicable legal requirements (including applicable stock exchange requirements), shares of Stock issued in
respect of Substitute Awards will be in addition to and will not reduce the Share Pool, but, notwithstanding anything in Section 4(a) to the contrary, if any Substitute Award is settled in cash or expires, becomes unexercisable, terminates or
is forfeited to or repurchased by the Company, in each case, without the issuance (or retention (in the case of Restricted Stock)) of Stock, the shares of Stock previously subject to such Award will not increase the Share Pool or otherwise be
available for future issuance under the Plan. The Administrator will determine the extent to which the terms and conditions of the Plan apply to Substitute Awards, if at all; provided that Substitute Awards will not be subject to, and will
not count against, the individual limits described in Section 4(d). 
 (c) Type of Shares. The shares of
Stock issued under the Plan may be shares of authorized but unissued Stock, treasury Stock, or Stock acquired in an open-market transaction. No fractional shares of Stock will be issued under the Plan. 

(d) Individual Limits. 

(1) The following additional limits apply to Awards of the specified type granted to any person in any calendar year: 

(A) Stock Options: 750,000 shares of Stock. 

(B) SARs: 750,000 shares of Stock. 

(C) Awards other than Stock Options and SARs: 750,000 shares of Stock. 

In applying the foregoing limits, (i) all Awards of the specified type granted to the same person in the same calendar year are
aggregated and made subject to one limit; (ii) the limits applicable to Stock Options and SARs refer to the number of shares of Stock underlying those Awards; and (iii) the share limit under clause (C) refers to the maximum number of
shares of Stock that may be issued, or the value of which may be paid in cash or other property, under Awards of the type specified in clause (C), assuming maximum payout levels. 

(2) Notwithstanding the foregoing limits, the aggregate value of all compensation granted or paid to any Director with respect to any
calendar year, including Awards granted under the Plan and cash fees or other compensation paid by the Company to such Director outside of the Plan, in each case, for his or her services as a Director during such calendar year, may not exceed
$550,000 in the aggregate, calculating the value of any Awards based on the grant date fair value in accordance with the Accounting Rules and assuming maximum payout levels.

 5. ELIGIBILITY AND PARTICIPATION 

The Administrator will select Participants from among key Employees and Directors of, and consultants and advisors to, the Company and its
subsidiaries. Eligibility for ISOs is limited to employees of the Company or of a “parent corporation” or “subsidiary corporation” of the Company as those terms are defined in Section 424 of the Code. Eligibility for NSOs
and SARs is limited to individuals who are providing direct services on the date of grant of the Award to the Company or to a subsidiary of the Company that would be described in the first sentence of
Section 1.409A-1(b)(5)(iii)(E) of the Treasury Regulations. 
 6. RULES
APPLICABLE TO AWARDS 
 (a) All Awards. 

(1) Award Provisions. The Administrator will determine the terms and conditions of all Awards, subject to the
limitations provided herein. By accepting (or, under such rules as the Administrator may prescribe, being deemed to have accepted) an Award, the Participant will be deemed to have agreed to the terms and conditions of the Award and the Plan.
Notwithstanding any provision of the Plan to the contrary, Substitute Awards may contain terms and conditions that are inconsistent with the terms and conditions specified herein, as determined by the Administrator. 

(2) Term of Plan. No Awards may be made after ten years from the Date of Adoption, but previously granted Awards
may continue beyond that date in accordance with their terms. 
 (3) Transferability. Neither ISOs nor, except as
the Administrator otherwise expressly provides in accordance with the third sentence of this Section 6(a)(3), other Awards may be transferred other than by will or by the laws of descent and distribution. During a Participant’s lifetime,
ISOs and, except as the Administrator otherwise expressly provides in accordance with the third sentence of this Section 6(a)(3), SARs and NSOs may be exercised only by the Participant. The Administrator may permit the transfer of Awards other
than ISOs, subject to applicable securities and other laws and such terms and conditions as the Administrator may determine. 
 (4)
Vesting; Exercisability. The Administrator will determine the time or times at which an Award vests or becomes exercisable and the terms and conditions on which a Stock Option or SAR remains exercisable. Without limiting the
foregoing, the Administrator may at any time accelerate the vesting and/or exercisability of an Award (or any portion thereof), regardless of any adverse or potentially adverse tax or other consequences resulting from such acceleration. Unless the
Administrator expressly provides otherwise, however, the following rules will apply if a Participant’s Employment ceases: 

(A) Except as provided in (B) and (C) below, immediately upon the cessation of the Participant’s Employment
each Stock Option and SAR (or portion thereof) that is then held by the Participant or by the Participant’s permitted transferees, if any, will cease to be exercisable and will terminate, and each other Award that is then held by the
Participant or by the Participant’s permitted transferees, if any, to the extent not then vested, will be forfeited. 

  
 -3- 

 (B) Subject to (C) and (D) below, each vested and unexercised
Stock Option and SAR (or portion thereof) held by the Participant or the Participant’s permitted transferees, if any, immediately prior to the cessation of the Participant’s Employment, to the extent then exercisable, will remain
exercisable for the lesser of (i) a period of three months following such cessation of Employment or (ii) the period ending on the latest date on which such Stock Option or SAR could have been exercised without regard to this
Section 6(a)(4), and will thereupon immediately terminate. 
 (C) Subject to (D) below, each vested and
unexercised Stock Option and SAR (or portion thereof) held by a Participant or the Participant’s permitted transferees, if any, immediately prior to the cessation of the Participant’s Employment due to his or her death, to the extent then
exercisable, will remain exercisable for the lesser of (i) the one-year period ending on the first anniversary of the Participant’s death or (ii) the period ending on the latest date on which
such Stock Option or SAR could have been exercised without regard to this Section 6(a)(4), and will thereupon immediately terminate. 

(D) All Awards (whether or not vested or exercisable) held by a Participant or the Participant’s permitted
transferees, if any, immediately prior to the cessation of the Participant’s Employment will immediately terminate upon such cessation of Employment if the termination is for Cause or occurs in circumstances that in the determination of the
Administrator would have constituted grounds for the Participant’s Employment to be terminated for Cause (in each case, without regard to the lapsing of any required notice or cure periods in connection therewith). 

(5) Recovery of Compensation. The Administrator may provide in any case that any outstanding Award (whether or not vested
or exercisable), the proceeds from the exercise or disposition of any Award or Stock acquired under any Award, and any other amounts received in respect of any Award or Stock acquired under any Award will be subject to forfeiture and disgorgement to
the Company, with interest and other related earnings, (i) if the Participant to whom the Award was granted is not in compliance with any provision of the Plan or any applicable Award, any
non-competition, non-solicitation, no-hire, non-disparagement, confidentiality, invention
assignment, or other restrictive covenant by which he or she is bound, or any policy of the Company or any of its subsidiaries that is applicable to the Participant and that provides for forfeiture, disgorgement or clawback with respect to incentive
compensation that includes Awards under the Plan; or (ii) to the extent required by law or applicable stock exchange listing standards, including, without limitation, Section 10D of the Securities Exchange Act of 1934, as amended. Each
Participant, by accepting or being deemed to have accepted an Award under the Plan, agrees (or will be deemed to have agreed) to cooperate fully with the Administrator, and to cause any and all permitted transferees of the Participant to cooperate
fully with the Administrator, to effectuate any forfeiture or disgorgement described in this Section 6(a)(5). Neither the Administrator nor the Company nor any other person, other than the Participant and his or her permitted transferees, if
any, will be responsible for any adverse tax or other consequences to a Participant or his or her permitted transferees, if any, that may arise in connection with this Section 6(a)(5). 

  
 -4- 

 (6) Taxes. The issuance, delivery, vesting, and retention of
Stock, cash or other property under an Award are conditioned upon the full satisfaction by the Participant of all tax and other withholding requirements with respect to the Award. The Administrator will prescribe such rules for the withholding of
taxes and other amounts with respect to any Award as it deems necessary. The Administrator may hold back shares of Stock from an Award or permit a Participant to tender previously-owned shares of Stock in satisfaction of tax or other withholding
requirements (but not in excess of the maximum withholding amount consistent with the Award being subject to equity accounting treatment under the Accounting Rules). Any amounts withheld pursuant to this Section 6(a)(6) will be treated as
though such payment had been made directly to the Participant. 
 (7) Dividend Equivalents. The
Administrator may provide for the payment of amounts, on such terms and subject to conditions established by the Administrator, in lieu of cash dividends or other cash distributions with respect to Stock subject to an Award, whether or not the
holder of such Award is otherwise entitled to share in the actual dividend or distribution in respect of such Award. Subject to Section 6(a)(10), any entitlement to dividend equivalents or similar entitlements will be established and
administered either consistent with an exemption from, or in compliance with, the applicable requirements of Section 409A. Dividends and dividend equivalent amounts payable in respect of Awards that are subject to restrictions may be subject to
such limitations or restrictions as the Administrator may impose. 
 (8) Rights Limited. Nothing in the Plan or
any Award will be construed as giving any person the right to be granted an Award or to continued employment or service with the Company or any of its subsidiaries, or any rights as a stockholder except as to shares of Stock actually issued under
the Plan. The loss of existing or potential profit in any Award will not constitute an element of damages in the event of a termination of a Participant’s Employment for any reason, even if the termination is in violation of an obligation of
the Company or any of its subsidiaries to the Participant. 
 (9) Coordination with Other Plans. Awards under the
Plan may be granted in tandem with, or in satisfaction of or substitution for, other Awards under the Plan or awards made under other compensatory plans or programs of the Company or any of its subsidiaries. For example, but without limiting the
generality of the foregoing, awards under other compensatory plans or programs of the Company or any of its subsidiaries may be settled in shares of Stock (including, without limitation, Unrestricted Stock) under the Plan if the Administrator so
determines, in which case the shares will be treated as issued under the Plan (and will reduce the Share Pool in accordance with the rules set forth in Section 4). 

(10) Section 409A. 

(A) Without limiting the generality of Section 11(b), each Award will contain such terms as the Administrator
determines and will be construed and administered such that the Award either qualifies for an exemption from the requirements of Section 409A or satisfies such requirements. 

  
 -5- 

 (B) If a Participant is determined on the date of the
Participant’s termination of Employment to be a “specified employee” within the meaning of that term under Section 409A(a)(2)(B) of the Code, then, with regard to any payment that is considered nonqualified deferred compensation
under Section 409A, to the extent applicable, payable on account of a “separation from service”, such payment will be made or provided on the date that is the earlier of (i) the first business day following the expiration of the six-month period measured from the date of such “separation from service” and (ii) the date of the Participant’s death (the “Delay Period”). Upon the expiration of the Delay
Period, all payments delayed pursuant to this Section 6(a)(10)(B) (whether they would have otherwise been payable in a single lump sum or in installments in the absence of such delay) will be paid on the first business day following the
expiration of the Delay Period in a lump sum and any remaining payments due under the Award will be paid in accordance with the normal payment dates specified for them in the applicable Award agreement. 

(C) With regard to any payment considered to be nonqualified deferred compensation under Section 409A, to the
extent applicable, that is payable upon a change in control of the Company or other similar event, to the extent required to avoid the imposition of any additional tax, interest, or penalty under Section 409A, no amount will be payable unless
such change in control constitutes a “change in control event” within the meaning of Section 1.409A-3(i)(5) of the Treasury Regulations. 

(D) For purposes of Section 409A, each payment made under the Plan will be treated as a separate payment. 

(b) Stock Options and SARs. 

(1) Time and Manner of Exercise. Unless the Administrator expressly provides otherwise, no Stock Option or SAR will
be considered to have been exercised until the Administrator receives a notice of exercise in a form acceptable to the Administrator that is signed by the appropriate person and accompanied by any payment required under the Award. Any attempt to
exercise a Stock Option or SAR by any person other than the Participant will not be given effect unless the Administrator has received such evidence as it may require that the person exercising the Award has the right to do so. 

(2) Exercise Price. The exercise price (or the base value from which appreciation is to be measured) per share of
each Award requiring exercise must be no less than 100% (in the case of an ISO granted to a 10-percent stockholder within the meaning of Section 422(b)(6) of the Code, 110%) of the Fair Market Value of a
share of Stock, determined as of the date of grant, or such higher amount as the Administrator may determine in connection with the grant. 

(3) Payment of Exercise Price. Where the exercise of an Award (or portion thereof) is to be accompanied by a
payment, payment of the exercise price must be made by cash or check acceptable to the Administrator or, if so permitted by the Administrator and if legally permissible, (i) through the delivery of previously acquired unrestricted shares of
Stock, or the withholding of unrestricted shares of Stock otherwise issuable upon exercise, in either case, that 

  
 -6- 

 
have a Fair Market Value equal to the exercise price; (ii) through a broker-assisted exercise program acceptable to the Administrator; (iii) by other means acceptable to the
Administrator; or (iv) by any combination of the foregoing permissible forms of payment. The delivery of previously acquired shares in payment of the exercise price under clause (i) above may be accomplished either by actual delivery or by
constructive delivery through attestation of ownership, subject to such rules as the Administrator may prescribe. 
 (4) Maximum
Term. The maximum term of Stock Options and SARs must not exceed 10 years from the date of grant (or five years from the date of grant in the case of an ISO granted to a 10-percent stockholder
described in Section 6(b)(2)). 
 (5) Repricing. Except in connection with a corporate transaction involving
the Company (which term includes, without limitation, any stock dividend, stock split, extraordinary cash dividend, recapitalization, reorganization, merger, consolidation, split up, spin-off, combination or
exchange of shares) or as otherwise contemplated by Section 7 below, The Company may not, without obtaining stockholder approval, (i) amend the terms of outstanding Stock Options or SARs to reduce the exercise price or base value of such
Stock Options or SARs; (ii) cancel outstanding Stock Options or SARs in exchange for Stock Options or SARs with an exercise price or base value that is less than the exercise price or base value of the original Stock Options or SARs; or
(iii) cancel outstanding Stock Options or SARs that have an exercise price or base value greater than the Fair Market Value of a share of Stock on the date of such cancellation in exchange for cash or other consideration. 

7. EFFECT OF CERTAIN TRANSACTIONS 

(a) Covered Transactions. Except as otherwise expressly provided in an Award agreement or by the
Administrator, the following provisions will apply in the event of a Covered Transaction: 
 (1) Assumption or
Substitution. If the Covered Transaction is one in which there is an acquiring or surviving entity, the Administrator may provide for (i) the assumption or continuation of some or all outstanding Awards or any portion thereof or
(ii) the grant of new awards in substitution therefor by the acquiror or survivor or an affiliate of the acquiror or survivor. 

(2) Cash-Out of Awards. Subject to Section 7(a)(5), the Administrator
may provide for payment (a “cash-out”), with respect to some or all Awards or any portion thereof (including only the vested portion thereof), equal in the case of each applicable Award or
portion thereof to the excess, if any, of (i) the Fair Market Value of a share of Stock multiplied by the number of shares of Stock subject to the Award or such portion, minus (ii) the aggregate exercise or purchase price, if any, of such
Award or portion (or, in the case of a SAR, the aggregate base value above which appreciation is measured), in each case, on such payment and other terms and subject to such conditions (which need not be the same as the terms and conditions
applicable to holders of Stock generally ) as the Administrator determines, including that any amounts paid in respect of such Award in connection with the Covered Transaction be placed in escrow or otherwise made subject to such restrictions as the
Administrator deems appropriate. For the avoidance of doubt, if the per share exercise or purchase price (or base value) of an Award or portion thereof is equal to or greater than the Fair Market Value of one share of Stock, such Award or portion
may be cancelled with no payment due hereunder or otherwise in respect thereof. 

  
 -7- 

 (3) Acceleration of Certain Awards. Subject to
Section 7(a)(5), the Administrator may provide that any Award requiring exercise will become exercisable, in full or in part, and/or that the issuance of any shares of Stock remaining issuable under any outstanding Award of Stock Units
(including Restricted Stock Units and Performance Awards to the extent consisting of Stock Units) will be accelerated, in full or in part, in each case, on a basis that gives the holder of the Award a reasonable opportunity, as determined by the
Administrator, following the exercise of the Award or the issuance of the shares, as the case may be, to participate as a stockholder in the Covered Transaction. 

(4) Termination of Awards upon Consummation of Covered Transaction. Except as the Administrator may otherwise
determine, each Award will automatically terminate (and in the case of outstanding shares of Restricted Stock, will automatically be forfeited) immediately upon the consummation of the Covered Transaction, other than (i) any Award that is
assumed, continued or substituted for pursuant to Section 7(a)(1) and (ii) any Award that by its terms, or as a result of action taken by the Administrator, continues following the Covered Transaction. 

(5) Additional Limitations. Any share of Stock and any cash or other property delivered pursuant to
Section 7(a)(2) or Section 7(a)(3) with respect to an Award may, in the discretion of the Administrator, contain such limitations or restrictions, if any, as the Administrator deems appropriate, including to reflect any performance or
other vesting conditions to which the Award was subject and that did not lapse (and were not satisfied) in connection with the Covered Transaction. For purposes of the immediately preceding sentence, a
cash-out under Section 7(a)(2) or an acceleration under Section 7(a)(3) will not, in and of itself, be treated as the lapsing (or satisfaction) of a performance or other vesting condition. In the
case of Restricted Stock that does not vest and is not forfeited in connection with the Covered Transaction, the Administrator may require that any amounts delivered, exchanged or otherwise paid in respect of such Stock in connection with the
Covered Transaction be placed in escrow or otherwise made subject to such restrictions as the Administrator deems appropriate to carry out the intent of the Plan. 

(6) Uniform Treatment. For the avoidance of doubt, the Administrator need not treat Participants or Awards (or
portions thereof) in a uniform matter, and may treat different Participants and/or Awards differently, in connection with a Covered Transaction. 

(b) Changes in and Distributions with Respect to Stock. 

(1) Basic Adjustment Provisions. In the event of a stock dividend, stock split or combination of shares (including
a reverse stock split), recapitalization or other change in the Company’s capital structure that constitutes an equity restructuring within the meaning of the Accounting Rules, the Administrator will make appropriate adjustments to the maximum
number of shares of Stock specified in Section 4(a) that may be issued under the Plan, the individual limits described in Section 4(d), the number and kind of shares of stock or securities underlying Awards then outstanding or subsequently
granted, any exercise or purchase prices (or base values) relating to Awards and any other provision of Awards affected by such change. 

  
 -8- 

 (2) Certain Other Adjustments. The Administrator may also make
adjustments of the type described in Section 7(b)(1) to take into account distributions to stockholders other than those provided for in Section 7(a) and 7(b)(1), or any other event, if the Administrator determines that adjustments are
appropriate to avoid distortion in the operation of the Plan or any Award. 
 (3) Continuing Application of Plan
Terms. References in the Plan to shares of Stock will be construed to include any stock or securities resulting from an adjustment pursuant to this Section 7. 

8. LEGAL CONDITIONS ON THE ISSUANCE OF STOCK

 The Company will not be obligated to issue any shares of Stock pursuant to the Plan or to remove any restriction from shares of Stock
previously issued under the Plan until: (i) the Company is satisfied that all legal matters in connection with the issuance of such shares have been addressed and resolved; (ii) if the outstanding Stock is at the time of issuance listed on
any stock exchange or national market system, the shares to be issued have been listed or authorized to be listed on such exchange or system upon official notice of issuance; and (iii) all conditions of the Award have been satisfied or waived.
The Company may require, as a condition to the exercise of an Award or the issuance of shares of Stock under an Award, such representations or agreements as counsel for the Company may consider appropriate to avoid violation of the Securities Act of
1933, as amended, or any applicable state or non-U.S. securities law. Any Stock issued under the Plan will be evidenced in such manner as the Administrator determines appropriate, including book-entry
registration or delivery of stock certificates. In the event that the Administrator determines that stock certificates will be issued in connection with Stock issued under the Plan, the Administrator may require that such certificates bear an
appropriate legend reflecting any restriction on transfer applicable to such Stock, and the Company may hold the certificates pending the lapse of the applicable restrictions. 

9. AMENDMENT AND TERMINATION 

The Administrator may at any time or times amend the Plan or any outstanding Award for any purpose which may at the time be permitted by
applicable law, and may at any time terminate the Plan as to any future grants of Awards; provided that, except as otherwise expressly provided in the Plan or the applicable Award, the Administrator may not, without the Participant’s
consent, alter the terms of an Award so as to materially and adversely affect the Participant’s rights under the Award, unless the Administrator expressly reserved the right to do in the Plan or at the time the applicable Award was granted. Any amendments to the Plan will be conditioned upon stockholder approval only to the extent, if any, such approval is required by applicable law (including the Code) or stock exchange requirements, as
determined by the Administrator. For the avoidance of doubt, no adjustment to any Award pursuant to the terms of Section 7 will be treated as an amendment requiring a Participant’s consent. 

  
 -9- 

 10. OTHER COMPENSATION ARRANGEMENTS 

The existence of the Plan or the grant of any Award will not affect the right of the Company or any of its subsidiaries to grant any person
bonuses or other compensation in addition to Awards under the Plan. 
 11. MISCELLANEOUS 

(a) Waiver of Jury Trial. By accepting or being deemed to have accepted an Award under the Plan, each Participant
waives (or will be deemed to have waived), to the maximum extent permitted under applicable law, any right to a trial by jury in any action, proceeding or counterclaim concerning any rights under the Plan or any Award, or under any amendment,
waiver, consent, instrument, document or other agreement delivered or which in the future may be delivered in connection therewith, and agrees (or will be deemed to have agreed) that any such action, proceedings or counterclaim will be tried before
a court and not before a jury. By accepting or being deemed to have accepted an Award under the Plan, each Participant certifies that no officer, representative, or attorney of the Company has represented, expressly or otherwise, that the Company
would not, in the event of any action, proceeding, or counterclaim, seek to enforce the foregoing waivers. Notwithstanding anything to the contrary in the Plan, nothing herein is to be construed as limiting the ability of the Company and a
Participant to agree to submit any dispute arising under the terms of the Plan or any Award to binding arbitration or as limiting the ability of the Company to require any individual to agree to submit such disputes to binding arbitration as a
condition of receiving an Award hereunder. 
 (b) Limitation of Liability. Notwithstanding anything to the
contrary in the Plan or any Award, neither the Company, nor any of its subsidiaries, nor the Administrator, nor any person acting on behalf of the Company, any of its subsidiaries, or the Administrator, will be liable to any Participant, to any
permitted transferee, to the estate or beneficiary of any Participant or any permitted transferee, or to any other person by reason of any acceleration of income, any additional tax, or any penalty, interest or other liability asserted by reason of
the failure of an Award to satisfy the requirements of Section 422 or Section 409A or by reason of Section 4999 of the Code, or otherwise asserted with respect to any Award. 

(c) Unfunded Plan. The Company’s obligations under the Plan are unfunded, and no Participant will have any
right to specific assets of the Company in respect of any Award. Participants will be general unsecured creditors of the Company with respect to any amounts due or payable under the Plan. 

(d) Section 162(m). To the extent applicable, Awards granted pursuant to the Plan are intended to be eligible for
exemption from the limitations of Section 162(m) of the Code by reason of the post-initial public offering transition relief set forth in Section 1.162-27(f) of the Treasury Regulations. 

12. ESTABLISHMENT OF SUB-PLANS 

The Administrator may at any time and from time to time establish one or more sub-plans under the Plan
(for local law compliance purposes or other purposes or administrative reasons determined by the Administrator) by adopting supplements to the Plan containing, in each case, 

  
 -10- 

 
(i) such limitations on the Administrator’s discretion under the Plan and (ii) such additional terms and conditions, as the Administrator deems necessary or desirable. Each supplement
so established will be deemed to be part of the Plan but will apply only to Participants within the group to which the supplement applies (as determined by the Administrator). 

13. GOVERNING LAW 

(a) Certain Requirements of Corporate Law. Awards and shares of Stock will be granted, issued and administered
consistent with the requirements of applicable Delaware law relating to the issuance of stock and the consideration to be received therefor, and with the applicable requirements of the stock exchanges or other trading systems on which the Stock is
listed or entered for trading, in each case, as determined by the Administrator. 
 (b) Other Matters. Except as
otherwise provided by the express terms of an Award agreement, under a sub-plan described in Section 12 or as provided in Section 13(a), the domestic substantive laws of the Commonwealth of
Massachusetts govern the provisions of the Plan and of Awards under the Plan and all claims or disputes arising out of or based upon the Plan or any Award under the Plan or relating to the subject matter hereof or thereof, without giving effect to
any choice or conflict of laws provision or rule that would cause the application of the domestic substantive laws of any other jurisdiction. 

(c) Jurisdiction. By accepting (or being deemed to have accepted) an Award, each Participant agrees or will be
deemed to have agreed to (i) submit irrevocably and unconditionally to the jurisdiction of the federal and state courts located within the geographic boundaries of the United States District Court for the District of Massachusetts for the
purpose of any suit, action or other proceeding arising out of or based upon the Plan or any Award; (ii) not commence any suit, action or other proceeding arising out of or based upon the Plan or any Award, except in the federal and state
courts located within the geographic boundaries of the United States District Court for the District of Massachusetts; and (iii) waive, and not assert, by way of motion as a defense or otherwise, in any such suit, action or proceeding, any
claim that he or she is not subject personally to the jurisdiction of the above-named courts that his or her property is exempt or immune from attachment or execution, that the suit, action or proceeding is brought in an inconvenient forum, that the
venue of the suit, action or proceeding is improper or that the Plan or any Award or the subject matter thereof may not be enforced in or by such court.

determine; (ii) to one or more officers of the Company the power to grant Awards to the extent permitted by Section 152 or 157(c) of the Delaware General Corporation Law; and (iii) to such Employees or other persons as it determines

delegation, as applicable.

written designation (in a form acceptable to the Administrator) most recently filed with the Administrator by the Participant prior to his or her death and not subsequently revoked, or, if there is no such designated beneficiary, the executor or

acceptable to the Administrator. 
 “Board”: The Board of Directors of the Company. 

  
 A-1 

 “Cause”: In the case of any Participant who is party to an offer letter or employment or
severance-benefit agreement that contains a definition of “Cause,” the definition set forth in such letter or agreement applies with respect to such Participant for purposes of the Plan for so long as such letter or agreement is in effect.
In every other case, “Cause” means, as determined by the Administrator, (i) a substantial failure of the Participant to perform the Participant’s duties and responsibilities to the Company or any of its subsidiaries or
substantial negligence in the performance of such duties and responsibilities; (ii) the commission by the Participant of a felony or a crime involving moral turpitude; (iii) the commission by the Participant of theft, fraud, embezzlement,
material breach of trust or any material act of dishonesty involving the Company or any of its subsidiaries; (iv) a significant violation by the Participant of the code of conduct of the Company or any of its subsidiaries of any material policy
of the Company or any of its subsidiaries, or of any statutory or common law duty of loyalty to the Company or any of its subsidiaries; (v) material breach of any of the terms of the Plan or any Award made under the Plan, or of the terms of any
other agreement between the Company or any of its subsidiaries and the Participant; or (vi) other conduct by the Participant that could be expected to be harmful to the business, interests or reputation of the Company. 

“Change in Control”: The occurrence of any of the following events: 
  

	 	(1)	 A change in the ownership of the Company which occurs on the date that any one person, or more than one
person acting as a group (“Person”), acquires ownership of the stock of the Company that, together with the stock held by such Person, constitutes more than 50% of the total voting power of the stock of the Company.

  

	 	(2)	 A change in the effective control of the Company which occurs on the date that a majority of members of
the Board is replaced during any twelve (12)-month period by directors whose appointment or election is not endorsed by a majority of the members of the Board prior to the date of the appointment or election. For purposes of this clause, if any
Person is considered to be in effective control of the Company, the acquisition of additional control of the Company by the same Person will not be considered a Change in Control. 

 

	 	(3)	 A change in the ownership of a substantial portion of the Company’s assets which occurs on the date
that any Person acquires (or has acquired during the twelve (12)-month period ending on the date of the most recent acquisition by such Person) assets from the Company that have a total gross fair market value equal to or more than 50% of the total
gross fair market value of all of the assets of the Company immediately prior to such acquisition. For purposes of this clause, gross fair market value means the value of the assets of the Company, or the value of the assets being disposed of,
determined without regard to any liabilities associated with such assets. 

 For purposes of this definition, persons will
be considered to be acting as a group if they are owners of a corporation that enters into a merger, consolidation, purchase, or acquisition of stock, or similar business transaction with the Company. 

  
 A-2 

 Notwithstanding the foregoing, a transaction will not be deemed a Change in Control unless
the transaction qualifies as a change in control event within the meaning of Section 409A. 
 Further and for the avoidance of doubt, a
transaction will not constitute a Change in Control if: (i) its sole purpose is to change the jurisdiction of the Company’s incorporation or (ii) its sole purpose is to create a holding company that will be owned in substantially the
same proportions by the persons who held the Company’s securities immediately before such transaction. 
 “Code”: The U.S. Internal
Revenue Code of 1986, as from time to time amended and in effect, or any successor statute as from time to time in effect. 
 “Company”:
LogicBio Therapeutics, Inc., a Delaware corporation. 
 “Compensation Committee”: The Compensation Committee of the Board. 

“Covered Transaction”: Any of (i) a consolidation, merger or similar transaction or series of related transactions, including a sale or
other disposition of stock, in which the Company is not the surviving corporation or which results in the acquisition of all or substantially all of the Company’s then-outstanding common stock by a single person or entity or by a group of
persons and/or entities acting in concert; (ii) a sale or transfer of all or substantially all the Company’s assets; (iii) a Change in Control; or (iv) a dissolution or liquidation of the Company. Where a Covered Transaction
involves a tender offer that is reasonably expected to be followed by a merger described in clause (i) (as determined by the Administrator), the Covered Transaction will be deemed to have occurred upon consummation of the tender offer. 

“Date of Adoption”: The earlier of the date the Plan was approved by the Company’s stockholders or adopted by the Board, as determined
by the Committee. 
 “Director”: A member of the Board who is not an Employee. 

“Employee”: Any person who is employed by the Company or any of its subsidiaries. 

“Employment”: A Participant’s employment or other service relationship with the Company or any of its subsidiaries. Employment will be
deemed to continue, unless the Administrator otherwise determines, so long as the Participant is employed by, or otherwise is providing services in a capacity described in Section 5 to, the Company or any of its subsidiaries. If a
Participant’s employment or other service relationship is with any subsidiary of the Company and that entity ceases to be a subsidiary of the Company, the Participant’s Employment will be deemed to have terminated when the entity ceases to
be a subsidiary of the Company unless the Participant transfers Employment to the Company or one of its remaining subsidiaries. Notwithstanding the foregoing, in construing the provisions of any Award relating to the payment of “nonqualified
deferred compensation” (subject to Section 409A) upon a termination or cessation of Employment, references to termination or cessation of employment, separation from service, retirement or similar or correlative terms will be construed to
require a “separation from service” (as that term is defined in Section 1.409A-1(h) of the Treasury Regulations) from the Company and from all other corporations and trades or businesses, if
any, that would be treated as a single “service recipient” with the Company under Section 1.409A-1(h)(3) of the
