Employment Agreement, dated May 12, 2023, by and between the Registrant and Alex C. Sapir

Start Date; Term of Employment. The Executive’s employment under this Agreement will commence on May 12, 2023 (the “Start Date”) and will continue until terminated by either Party. The effective date of any termination of the Executive’s employment hereunder is hereinafter referred to as the “Termination Date”, and the period of time between the Start Date and the Termination Date is hereinafter referred to as the “Term of Employment”. Effective upon any Termination Date, this Agreement will automatically terminate and will be of no further force or effect, except as otherwise provided in Section 14 hereof, and the Executive shall immediately resign, in writing, from all positions then held by the Executive with the Company and its affiliates, unless otherwise expressly agreed to by the Company and the Executive. For the avoidance of doubt, the Executive’s employment is at-will, and either the Executive or the Company may terminate the Executive’s employment hereunder any time, for any or no reason, without advance notice (except for any notice expressly required under Section 6 below).

Initial Position as Special Advisor to the Interim Chief Executive Officer. As of the Start Date and continuing to June 30, 2023, at 11:59 pm, Executive shall serve as a Special Advisor (“Special Advisor”) to the Interim Chief Executive Officer of the Company. As a Special Advisor, Executive shall work on a less than full-time basis and will perform those duties assigned to Executive by the Interim Chief Executive Officer.

President and Chief Executive Officer. Beginning on July 1, 2023 (“CEO Start Date”) and continuing for the duration of the Term of Employment, Executive shall serve as the President and Chief Executive Officer of the Company (the “CEO”) and shall serve on the Company’s board of directors (the “Board”), subject to the Executive’s reelection thereto from time to time by the Company’s stockholders. The Board agrees that the governance committee will ensure that Executive is nominated to serve on the Board at all times during Executive’s employment as CEO hereunder.

Location. Executive will spend on average at least approximately 50% of his work time either in the Company’s office in Cambridge, Massachusetts, or in business travel as reasonably required by the Executive’s job duties, and shall otherwise work remotely from Executive’s home office in Executive’s principal state of residence in the State of North Carolina, or such other state; provided that Executive agrees not to relocate outside of the State of North Carolina without prior written notice to the Board.

Duties. During the Term of Employment, the Executive shall be responsible for the performance of those duties, and shall have such authorities and responsibilities, as are consistent with the Executive’s positions as Special Advisor and then CEO, as applicable, and such other duties, authorities and responsibilities not inconsistent with the Executive’s positions as may be assigned to the Executive by the Board from time to time. The Executive shall report to the Board and shall perform and discharge faithfully, diligently, and to the best of the Executive’s ability, the Executive’s duties and responsibilities hereunder. Subject to Executive’s part-time employment status prior to the CEO Start Date, the Executive shall devote substantially all of the Executive’s business time, loyalty, attention and efforts to the business and affairs of the Company and its affiliates; provided that the foregoing will not prevent the Executive from serving on the board of directors of one public company unaffiliated with the Company and/or providing academic instruction at an educational institution, so long as the Executive receives the Board’s prior express approval of any such activity, which approval shall not be unreasonably withheld, and such activities do not, individually or in the aggregate, create a potential conflict of interest or otherwise interfere with the Executive’s duties, obligations or restrictions hereunder. The Executive agrees to abide by the rules, regulations, instructions, personnel practices and policies of the Company and any changes therein that may be adopted from time to time by the Company.

Compensation. As full compensation for all services rendered by the Executive to the Company and any affiliate thereof, during the Term of Employment, the Company will provide to the Executive the following:

Base Salary. Effective as of the CEO Start Date, the Executive shall receive a base salary at the annualized rate of $650,000, less all applicable withholdings and deductions (the “Base Salary”). The Executive’s Base Salary shall be paid in equal installments in accordance with the Company’s regularly established payroll procedures. The Executive’s Base Salary will be reviewed on an annual or more frequent basis by the Board and is subject to change, in the sole and absolute discretion of the Board. Between the Start Date and the CEO Start Date, Executive shall receive a salary at the monthly rate of $27,000, less all applicable withholdings and deductions (“Special Advisor Salary”), which shall be paid in equal installments in accordance with the Company’s regularly established payroll procedures.

Annual Discretionary Bonus. Effective as of the CEO Start Date, for each calendar year during the Term of Employment (prorated for the calendar year which contains the CEO Start Date), the Executive will be eligible to earn an annual discretionary performance bonus (the “Annual Discretionary Bonus”) in an initial amount of up to 50% of the Executive’s Base Salary (the “Target Bonus”), based upon the Board’s assessment of the Executive’s performance and the Company’s attainment of targeted goals as set by the Board, after discussions with and input from Executive. To the extent the Executive’s Base Salary and/or target bonus percentage of Base Salary is changed during the year to which the performance bonus relates, the Target Bonus shall be calculated based on Base Salary actually paid during

such year (and not solely on the Executive’s Base Salary at the end of such year) and shall apply the initial target bonus percentage of Base Salary and the revised target bonus percentage of Base Salary based on the portion of the year during which each was in effect. The Board may determine to pay any earned Annual Discretionary Bonus in the form of cash, vested equity award(s), or a combination of cash and equity, in its sole and absolute discretion. Following the close of each calendar year, the Board will determine whether the Executive has achieved an Annual Discretionary Bonus for such year, and the amount of any such Annual Discretionary Bonus, based on the set criteria (which, for the avoidance of doubt, may be less than the Target Bonus). The Annual Discretionary Bonus, if earned, will be paid by no later than March 15 of the calendar year after the year to which it relates. No amount of the Annual Discretionary Bonus is guaranteed, and the Executive must remain employed by the Company in good standing through the date of payment of an Annual Discretionary Bonus in order to earn and receive such bonus, except as may be specifically set forth in Section 7 below. The Executive’s bonus eligibility, and the terms and conditions of the bonus (including the Target Bonus amount), will be reviewed on an annual or more frequent basis by the Board and are subject to change in the discretion of the Board.

Initial Stock Option Award. On the Start Date, the Company will grant to the Executive, subject to the Executive’s continued employment with the Company through the grant date, a one- time award consisting of nonqualified options to purchase 2,430,400 shares of the Company’s common stock (the “Shares”) at a per-Share exercise price equal to the grant date fair market value of one Share (the “Initial Option Award”), subject to all of the terms and conditions of the Company’s incentive equity plan and/or inducement plan, as applicable, an individual stock option award agreement consistent with the terms set forth herein, and any ancillary agreements with the Company that the Executive may be required to enter into as a condition of such grant (collectively, the “Equity Documents”), which will provide, among other things, that the Initial Option Award will: (1) vest and become exercisable over 4 years as follows: (i) as to 25% of the Shares underlying the Initial Option Award on the first anniversary of the Start Date and (ii) as to an additional 6.25% of the Shares underlying the Initial Option Award on the last day of each of the next 12 successive calendar quarters, provided in each case that the Executive remains employed by the Company and in compliance with the Equity Documents through each such vesting date; (2) have an option term of 10 years, and (3) permit a minimum of one year post-separation from service to exercise any portion of the Initial Option Award which is then vested and exercisable (and that has not otherwise become forfeited under the terms of the Equity Documents). Subject to the terms set forth in the preceding sentence and the accelerated vesting provision in Section 7 below, in the event of any conflict between any terms of this Agreement and any terms of the Equity Documents, the terms of the Equity Documents will prevail.

Additional Discretionary Equity Awards. During the Term of Employment, the Executive will be eligible to receive additional incentive equity awards, if any, at such times and on such terms and conditions as the Board shall, in its sole discretion, determine.

Paid Time Off. During the Term of Employment beginning with the CEO Start Date, the Executive shall be entitled to paid time off, vacation time plus sick time, consistent with the Company’s policies.

Business Expenses. Upon presentation of such substantiation and documentation as the Company may specify from time to time, the Executive will be reimbursed in accordance

with the Company’s expense reimbursement policy as in effect from time to time for all eligible out-of- pocket business expenses incurred and paid by the Executive during the Term of Employment.

Housing and Travel Allowance. The Company will provide the Executive with an additional cash allowance of up to $100,000 annually (pro-rated for any partial calendar year) to be applied by the Executive solely towards the rental cost of a personal apartment in the Greater Boston metropolitan region and to transportation expenses for Executive’s regular commuting trips to the Company’s offices in Cambridge, Massachusetts, in each case solely to the extent such costs or expenses are incurred during the Term of Employment (the “Housing and Travel Allowance”), which will be paid to the Executive on a monthly basis in arrears, subject to presentation by the Executive of such substantiation and documentation as the Company may specify from time to time. To the extent that such Housing and Travel Allowance will constitute taxable income to the Executive for a given calendar year, the Company will also provide the Executive with an additional cash gross-up amount (the “Housing Gross-Up Payment”) equal to the estimated amount of such taxable income (estimated at the highest federal and state tax rates applicable to a person living in the Commonwealth of Massachusetts), which will be paid to the Executive on or before December 31 of such year, regardless of whether Executive is employed through such payment date (but provided that Executive was employed by the Company for at least one day during such year). Annually the Board will review and determine in its sole discretion after good faith consultation with the Executive appropriate adjustments, if any, to the amount of the Housing and Travel Allowance for each subsequent year.

Employee Benefits. During the Term of Employment beginning with the CEO Start Date, the Executive will be eligible to participate in any employee benefit plan maintained by the Company for the benefit of its employees generally, subject to all of the terms and conditions (including eligibility requirements) of such plan. Notwithstanding the foregoing, the Company may modify or terminate any employee benefit plan at any time, in its sole and absolute discretion.

The Executive hereby acknowledges that in connection with entering into this Agreement, the Executive shall be required to enter into, and agrees to strictly abide by, an Employee Confidentiality and Assignment Agreement with the Company in the form attached as Exhibit A hereto (the “ECAA”).

Effect of Termination.

All Terminations Other Than by the Company Without Cause or by the Executive With Good Reason.

Termination by the Company Without Cause or by the Executive With Good Reason Within Eighteen Months Following a Change in Control. If a Qualifying Termination occurs within eighteen (18) months following a Change in Control, then the Executive shall be entitled to the Accrued Obligations.

the passage of time vest and become fully exercisable or non-forfeitable as of the Termination Date (collectively, the “Change in Control Severance Benefits”).

Release. As a condition of the Executive’s receipt of the Severance Benefits or the Change in Control Severance Benefits, as applicable, the Executive must execute and deliver to the Company a severance and release of claims agreement in a form to be provided by the Company (other than a standard release of employment-related claims and a mutual nondisparagement provision, such form will not include any new obligations or restrictive covenants imposed on Executive beyond those to which the Executive is otherwise subject as of the Termination Date under this Agreement or other agreements executed by Executive and the Company) (the “Severance Agreement”), which Severance Agreement must become irrevocable within 60 days following the Executive’s Termination Date (or such shorter period as may be directed by the Company). The Severance Benefits or the Change in Control Severance Benefits (other than any COBRA subsidy), as applicable, will be paid or commence to be paid in the first regular payroll beginning after the Severance Agreement becomes effective and irrevocable, provided that if the foregoing 60 day period (or such shorter period as may be directed by the Company) would end in a calendar year subsequent to the year in which the Executive’s employment ends, the Severance Benefits or Change in Control Severance Benefits (other than any COBRA subsidy), as applicable, will not be paid or begin to be paid before the first payroll of the subsequent calendar year (the date the Severance Benefits or Change in Control Severance Benefits, as applicable, commence pursuant to this sentence, the “Payment Date”). The Executive must continue to comply with the ECAA and any similar agreement with the Company or its affiliates in order to be eligible to continue receiving the Severance Benefits or Change in Control Severance Benefits, as applicable.

Change in Control Definition. For purposes of this Agreement, “Change in Control” shall mean the occurrence of any of the following events, provided that such event or occurrence constitutes a change in the ownership or effective control of the Company, or a change in the ownership of a substantial portion of the assets of the Company, as defined in Treasury Regulation §§ 1.409A-3(i)(5)(v), (vi) and (vii): (i) the acquisition by an individual, entity or group (within the meaning of Section 13(d)(3) or 14(d)(2) of the Securities Exchange Act of 1934 (the “Exchange Act”)) (a “Person”) of beneficial ownership of any capital stock of the Company if, after such acquisition, such Person beneficially owns (within the meaning of Rule 13d-3 under the Exchange Act) fifty percent (50%) or more of either (x) the then-outstanding shares of common stock of the Company (the “Outstanding Company Common Stock”) or (y) the combined voting power of the then-outstanding securities of the Company entitled to vote generally in the election of directors (the “Outstanding Company Voting Securities”); provided, however, that for purposes of this subsection (i), the following acquisitions shall not constitute a Change in Control: (1) any acquisition directly from the Company or (2) any acquisition by any entity pursuant to a Business Combination (as defined below) which complies with clauses (x) and (y) of subsection (iii) of this definition; or (ii) a change in the composition of the Board that results in the Continuing Directors (as defined below) no longer constituting a majority of the Board (or, if applicable, the Board of Directors of a successor corporation to the Company), where the term “Continuing Director” means at any date a member of the Board (x) who was a member of the Board on the Effective Date or (y) who was nominated or elected subsequent to such date by at least a majority of the directors who were Continuing Directors at the time of such nomination or election or whose election to the Board was recommended or endorsed by at least a majority of the directors who were

Withholding. The Company may withhold from any compensation and benefits payable under this Agreement all applicable federal, state, local, or other taxes, and any other applicable withholdings and deductions.

Section 409A.

Although the Company does not guarantee the tax treatment of any payments or benefits under this Agreement, the intent of the Parties is that the payments and benefits under this Agreement be exempt from or, to the extent not exempt, comply with, Section 409A of the Code and the regulations and guidance promulgated thereunder (collectively “Section 409A”), and, accordingly, to the maximum extent possible, this Agreement will be interpreted and construed consistent with such intent. Notwithstanding the foregoing, the Company does not guarantee any particular tax result, and in no event whatsoever will the Company, its affiliates, or their respective officers, directors, employees, counsel or other service providers, be liable for any tax, interest or penalty that may be imposed on the Executive by Section 409A or damages for failing to comply with Section 409A.

For purposes of Section 409A, the Executive’s right to receive installment payments pursuant to this Agreement shall be treated as a right to receive a series of separate payments and, accordingly, each installment payment will at all times be considered a separate and distinct payment. Whenever a payment hereunder specifies a payment period with reference to a number of days, the actual date of payment within the specified period shall be within the sole discretion of the Company.

To the extent that reimbursements or other in-kind benefits hereunder constitute “deferred compensation” subject to Section 409A, (x) all expenses or other reimbursements hereunder will be made on or prior to the last day of the taxable year following the taxable year in which such expenses were incurred by the Executive, (y) any right to reimbursement or in-kind benefits will not be subject to liquidation or exchange for another benefit, and (z) no such reimbursement, expenses eligible for reimbursement, or in-kind benefits provided in any taxable year will in any way affect the expenses eligible for reimbursement, or in-kind benefits to be provided, in any other taxable year.

Any other provision of this Agreement to the contrary notwithstanding, in no event will any payment or benefit hereunder that constitutes “deferred compensation” subject to Section 409A be subject to offset by any other amount unless otherwise permitted by Section 409A.

A termination of employment will not be deemed to have occurred for purposes of any provision of this Agreement providing for the payment of any amounts or benefits that constitute “deferred compensation” subject to Section 409A upon or following a termination of employment, unless such termination is also a “separation from service” within the meaning of Section 409A, and, for purposes of any such provision, all references in this Agreement to the Executive’s “termination”, “termination of employment” or like terms will mean the Executive’s “separation from service” with the Company, and the date of such separation from service will be the date of termination for purposes of any such payment or benefit.

Notwithstanding any other provision of this Agreement to the contrary, if, at the time of the Executive’s separation from service, the Executive is a “specified employee” within the meaning and in accordance with Treasury Regulation Section 1.409A-1(i), then the Company will defer the payment or commencement of any “deferred compensation” subject to Section 409A that is payable upon separation from service (without any reduction in such payments or benefits ultimately paid or provided to the Executive) until the date that is six (6) months following separation from service or, if earlier, the earliest other date as is permitted under Section 409A (and any amounts that otherwise would have been paid during this deferral period will be paid in a lump sum on the day after the expiration of the six (6) month period or such shorter period, if applicable). The Company will determine in its sole discretion all matters relating to who is a “specified employee” and the application of and effects of the change in such determination.

Section 280G. In the event that any payments and other benefits provided for in this Agreement or otherwise payable to the Executive constitute “parachute payments” within the meaning of Section 280G of the Code, and, but for this paragraph, would be subject to the excise tax imposed by Section 4999 of the Code, then any post-termination severance payments and benefits payable under this Agreement or otherwise will be either (1) delivered in full or (2) delivered as to such lesser extent which would result in no portion of such payments and benefits being subject to excise tax under Section 4999 of the Code, whichever of the foregoing amounts, taking into account the applicable federal, state and local income taxes and the excise tax imposed by Section 4999 of the Code, results in the receipt by the Executive, on an after-tax basis, of the greatest amount of payments and benefits, notwithstanding that all or some portion of such benefits may be taxable under Section 4999 of the Code. If a reduction in the Executive’s payments and benefits is necessitated by the preceding sentence, such reduction will occur in the following order: (i) any cash amounts payable to the Executive, (ii) any benefits valued as parachute payments, and (iii) acceleration of vesting of any equity awards. Any determination required under this paragraph will be made in writing by the Company’s independent public accountants (the “Firm”), whose determination will be conclusive and binding upon the Executive and the Company. For purposes of making the calculations required by this paragraph, 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 the Executive will furnish to the Firm such information and documents as the Firm may reasonably request in order to make a determination under this paragraph. The Company will bear all costs the Firm may incur in connection with any calculations contemplated by this paragraph.

Clawback. To the maximum extent permitted by applicable law, all amounts paid or provided to the Executive hereunder shall be subject to any clawback or recoupment policy that may be maintained by the Company from time to time, and the requirements of any law or regulation applicable to the Company and governing the clawback or recoupment of executive compensation, or as set forth in any final non-appealable order by any court of competent jurisdiction or arbitrator.

Absence of Restrictions. The Executive represents and warrants that the Executive is not bound by any employment contracts, restrictive covenants or other restrictions that prevent the Executive from entering into employment with, or carrying out the Executive’s responsibilities for, the Company, or which are in any way inconsistent with any of the terms of this Agreement.

Notice. Any notice delivered under this Agreement shall be deemed duly delivered three (3) business days after it is sent by registered or certified mail, return receipt requested, postage prepaid, one (1) business day after it is sent for next-business day delivery via a reputable nationwide overnight courier service, or immediately upon hand delivery, in each case to the address of the recipient set forth below.

Applicable Law; Jury Trial Waiver. This Agreement shall be governed by and construed in accordance with the laws of the Commonwealth of Massachusetts (without reference to the conflict of laws provisions thereof). Any action, suit or other legal proceeding arising under or relating to any provision of this Agreement shall be commenced only in a court of the Commonwealth of Massachusetts (or, if appropriate, a federal court located within the Commonwealth of Massachusetts), and the Company and the Executive each consents to the jurisdiction of such a court. The Company and the Executive each hereby irrevocably waives any right to a trial by jury in any action, suit or other legal proceeding arising under or relating to any provision of this Agreement.

Successors and Assigns. This Agreement shall be binding upon and inure to the benefit of both Parties and their respective successors and assigns, including any corporation with which or into which the Company may be merged or which may succeed to its assets or business (and, as used in this Agreement, “Company” will mean the Company and any such successor corporation); provided, however, that the obligations of the Executive are personal and shall not be assigned by the Executive.

Survival. Sections 5 and 7 through 22 hereof will survive and continue in full force and effect in accordance with their respective terms notwithstanding any expiration or termination of the Term of Employment and/or this Agreement.

Pre-Employment Checks. The Executive acknowledges and agrees that the Executive’s employment, and this Agreement, are contingent upon satisfactory completion prior to the Start Date of pre-employment screening activities, including favorable reference checks of former employment, verification of the Executive’s ability to work in the United States, and educational background and criminal history checks. The Executive agrees to assist the Company as needed to facilitate the timely completion of such checks.

No Oral Modification, Waiver, Cancellation or Discharge. This Agreement may be amended or modified only by a written instrument executed by both the Company and the Executive. No delay or omission by the Company in exercising any right under this Agreement

shall operate as a waiver of that or any other right. A waiver or consent given by the Company on any one occasion shall be effective only in that instance and shall not be construed as a bar to or waiver of any right on any other occasion.

Captions and Pronouns. The captions of the sections of this Agreement are for convenience of reference only and in no way define, limit or affect the scope or substance of any section of this Agreement. Whenever the context may require, any pronouns used in this Agreement shall include the corresponding masculine, feminine or neuter forms, and the singular forms of nouns and pronouns shall include the plural, and vice versa.

Interpretation. The Parties agree that this Agreement will be construed without regard to any presumption or rule requiring construction or interpretation against the drafting Party. References in this Agreement to “include” or “including” should be read as though they said “without limitation” or equivalent forms. References in this Agreement to the “Board” shall include any authorized committee thereof.

Severability. Each provision of this Agreement must be interpreted in such manner as to be effective and valid under applicable law, but if any provision of this Agreement is held to be prohibited by or invalid under applicable law, such provision will be ineffective only to the extent of such prohibition or invalidity, without invalidating the remainder of such provision or the remaining provisions of this Agreement. Moreover, if a court of competent jurisdiction determines any of the provisions contained in this Agreement to be unenforceable because the provision is excessively broad in scope, whether as to duration, activity, geographic application, subject or otherwise, it will be construed, by limiting or reducing it to the extent legally permitted, so as to be enforceable to the extent compatible with then applicable law to achieve the intent of the Parties.

Counterparts. This Agreement may be executed in several counterparts, each of which will be deemed to be an original but all of which together will constitute one and the same instrument. Facsimile, PDF, and electronic counterpart signatures to and versions of this Agreement will be acceptable and binding on the Parties.
