Re:     Employment
Agreement

 

Dear Yishai:

 

On behalf of Gelesis, Inc. (the “Company”), I
am pleased to confirm our offer to continue your employment as Chief Executive Officer (“CEO”) and Founder of the Company. The
terms and conditions of your continued employment are set forth below in this letter agreement (the “Agreement”):

 

1.            Position.
As CEO, you will report to the Board of Directors of the Company (the “Board”) and have such powers and duties as may
from time to time be prescribed by the Board. You will also serve on the Board for so long as you remain CEO, provided that you shall
be deemed to have resigned from the Board and from any related positions upon ceasing to serve as CEO for any reason. This is a full-time
employment position. It is understood and agreed that, while you render services to the Company, you will not engage in any other employment,
consulting or other business activities (whether full-time or part-time), except as expressly authorized in writing by the Board. Notwithstanding
the foregoing, you may engage in religious, charitable and other community activities so long as such activities do not interfere or conflict
with your obligations to the Company.

 

2.            Effective
Date. The Effective Date of this Agreement shall be on the closing of the currently contemplated deSPAC transaction with Capstar Special
Purpose Acquisition Corp (or other entity) (“Effective Date”).

 

3.            Compensation
and Related Matters.

 

(a)            Base
Salary. The Company will pay you an initial base salary at the rate of $412,000 per year, payable in accordance with the Company’s
standard payroll schedule for its executives and subject to applicable deductions and withholdings. Your base salary will be subject to
periodic increases at the Company’s discretion. Your base salary in effect at any given time is referred to herein as the “Base
Salary.”

 

(b)            Annual
Bonus. You will initially be eligible to receive an annual performance bonus targeted at 50% of your Base Salary. The actual bonus
amount is discretionary and will be determined by the Company’s Board of Directors. To receive an annual bonus, you must be employed
by the Company as of December 31 of the year to which such bonus relates. Any annual bonus will be paid no later than March 15th
of the calendar year following the calendar year to which such bonus relates.

 

     

     

    

 

(c)            Expenses.
The Company will promptly reimburse you for all reasonable expenses incurred by you in performing services hereunder, in accordance with
the policies and procedures then in effect and established by the Company for its executives.

 

(d)            Benefits/Paid
Time Off. You will be eligible, subject to the terms of the applicable plans and programs, to participate in the employee benefits
and insurance programs generally made available to the Company’s full-time employees. You will be entitled to 25 days annually of
paid time off consistent with the terms of the Company’s paid time off policy for its executives, as in effect from time to time.
The Company reserves the right to modify, amend or cancel any of its benefits plans or programs at any time.

 

4.            Equity.
All options that you were previously granted to purchase the Company’s Common Stock shall continue to vest in accordance with your
Stock Option Agreements with the Company and the Gelesis 2006 Stock Incentive Plan, as amended, and the 2016 Stock Incentive Plan, as
amended as applicable.

 

5.            Location.
You will primarily work from the Company’s U.S. office, currently located in Boston, Massachusetts, provided, however, that you
may be required to travel on business as is necessary from time to time.

 

6.            At-Will
Employment; Date of Termination. At all times your employment is “at will,” meaning you or the Company may terminate it
at any time for any or no reason, subject to the terms of this Agreement. Your last day of employment regardless of the reason is referred
to herein as the “Date of Termination.” Given your role as a senior executive, in the event that you elect to end your
employment other than for Good Reason, the Company requires you to provide at least 30 days’ advance written notice to the Company.
Notwithstanding the foregoing, in the event you give such advance written notice, the Company may unilaterally accelerate the Date of
Termination, and such acceleration shall not result in a termination by the Company for purposes of this Agreement.

 

To the extent applicable, you shall be deemed to have resigned from
all officer and board member positions that you hold with the Company or any of its respective subsidiaries and affiliates upon the termination
of your employment regardless of the reason. You shall execute any documents in reasonable form as may be requested to confirm or effectuate
any such resignations.

 

7.            Accrued
Obligations. In the event of the ending of your employment regardless of the reason, the Company shall pay you (i) your Base
Salary and, if applicable, any accrued but unused vacation, through the Date of Termination, (ii) the amount of any documented expenses
properly incurred by you on behalf of the Company prior to any such termination and not yet reimbursed, and (iii) the awarded, but
unpaid portion, if any, of the annual performance bonus for any prior year (the “Accrued Obligations”).

 

     

     

    

 

8.            Severance
Pay and Benefits Upon a Qualifying Termination. In the event that a Qualifying Termination (as defined in Section 10)
occurs, then, in addition to you being entitled to the Accrued Obligations, and subject to (i) you signing a separation
agreement and release in a form and manner reasonably satisfactory to the Company, which shall include, without limitation, a
general release of claims against the Company and all related persons and entities and a reaffirmation of the Continuing
Obligations (as defined below) and, in the Company’s discretion, a one year post-employment noncompetition agreement that
is no more restrictive than the existing Non-Competition and Non-Solicitation Agreement, and shall provide that if you breach the
Continuing Obligations, all payments of the Severance Amount (as defined below) shall immediately cease (the “Separation
Agreement”), and (ii) the Separation Agreement becoming irrevocable, all within 60 days after the Date of Termination
(or such shorter period as set forth in the Separation Agreement):

 

(a)            the
Company shall pay you an amount equal to twelve (12) months of your Base Salary (the “Severance Amount”); and

 

(b)            subject
to your copayment of premium amounts at the applicable active employees’ rate and your proper election to receive benefits under
the Consolidated Omnibus Budget Reconciliation Act of 1985, as amended (“COBRA”), the Company shall pay to the group
health plan provider(s) or the COBRA provider a monthly payment equal to the monthly employer contribution that the Company would
have made to provide health insurance to you if you had remained employed by the Company until the earliest of (A) the twelve (12)
month anniversary of the Date of Termination; (B) your eligibility for group health plan benefits under any other employer’s
group health plan; or (C) the cessation of your continuation rights under COBRA; provided, however, that if the Company reasonably
determines that it cannot pay such amounts to the group health plan provider(s) or the COBRA provider (if applicable) without potentially
violating applicable law (including, without limitation, Section 2716 of the Public Health Service Act), then the Company shall convert
such payments to payroll payments directly to you for the time period specified above. Such payments, if to you, shall be subject to tax-related
deductions and withholdings and paid on the Company’s regular payroll dates.

 

The amounts
payable under this Section 8, to the extent taxable, shall be paid out in substantially equal installments in accordance with the
Company’s payroll practice over twelve (12) months commencing within 60 days after the Date of Termination; provided, however, that
if the 60-day period begins in one calendar year and ends in a second calendar year, the Severance Amount, to the extent it qualifies
as “non-qualified deferred compensation” within the meaning of Section 409A of the Internal Revenue Code of 1986, as
amended (the “Code”), shall begin to be paid in the second calendar year by the last day of such 60-day period;
provided, further, that the initial payment shall include a catch-up payment to cover amounts retroactive to the day immediately following
the Date of Termination. Each payment pursuant to this Agreement is intended to constitute a separate payment for purposes of Treasury
Regulation Section 1.409A-2(b)(2).

 

If your employment ends for any reason other than a Qualifying Termination,
you will be entitled to the Accrued Obligations and will not be entitled to any further compensation from the Company. For the avoidance
of doubt, if your employment ends due to your death or disability, you will receive the Accrued Obligations but will not be eligible for
severance pay and benefits, whether pursuant to this Section 8 or otherwise.

 

     

     

    

 

9.            Change
in Control Payment. The provisions of this Section 9 address your rights and obligations upon the occurrence of a Change in
Control of the Company. These provisions shall supplement, and be in addition to the provisions of Section 8 regarding severance
pay and benefits upon a termination of employment, if such termination of employment occurs within twelve (12) months after the
occurrence of the first event constituting a Change in Control. These provisions shall terminate and be of no further force or
effect beginning twelve (12) months after the occurrence of a Change in Control.

 

(a)            Change
in Control. If your employment is terminated by the Company without Cause or by you for Good Reason within twelve (12) months after
a Change in Control, then, subject to your signing of the Separation Agreement and the Separation Agreement becoming irrevocable, all
within 60 days after the Date of Termination, notwithstanding anything to the contrary in any applicable option agreement or stock-based
award agreement, all unvested stock options and other unvested stock-based awards held by you shall immediately accelerate and become
fully exercisable or nonforfeitable as of the Date of Termination.

 

10.            Definitions.
For the purposes of this Agreement, the following terms shall have the following meanings:

 

(a)            “Cause”
shall mean (i) your dishonest statements or acts with respect to the Company or any affiliate of the Company, or any current or prospective
customers, suppliers, vendors or other third parties with which such entity does business that results in or is reasonably anticipated
to result in harm to the Company; (ii) your commission of (A) a felony or (B) any misdemeanor involving moral turpitude,
deceit, dishonesty or fraud; (iii) your failure to perform your assigned duties and responsibilities, which failure continues, in
the reasonable judgment of the Board, for 30 days after written notice given to you describing such failure; (iv) your gross negligence,
willful misconduct or insubordination that results in or is reasonably anticipated to result in harm to the Company; (v) your violation
of any material provision of any agreement(s) between you and the Company or any Company policies including, without limitation,
this Agreement, the Restrictive Covenants Agreement, agreements relating to noncompetition, nonsolicitation, nondisclosure and/or assignment
of inventions or policies related to ethics or workplace conduct; or (vi) your failure to cooperate with a bona fide internal investigation
or an investigation by regulatory or law enforcement authorities, after being instructed by the Board to cooperate, or the willful destruction
or failure to preserve documents or other materials known to be relevant to such investigation or the inducement of others to fail to
cooperate or to produce documents or other materials in connection with such investigation.

 

(b)           “Change
of Control” shall mean any of the following:

 

(i)            any
 “person,” as such term is used in Sections 13(d) and 14(d) of the Securities Exchange Act of 1934, as amended
(the “Act”) (other than the Company, any of its subsidiaries, or any trustee, fiduciary or other person or entity
holding securities under any employee benefit plan or trust of the Company or any of its subsidiaries), together with all
 “affiliates” and “associates” (as such terms are defined in Rule 12b-2 under the Act) of such person,
shall become the “beneficial owner” (as such term is defined in Rule 13d-3 under the Act), directly or indirectly,
of securities of the Company representing fifty (50) percent or more of the combined voting power of the Company’s then
outstanding securities having the right to vote in an election of the Board (“Voting Securities”) (in such case
other than as a result of an acquisition of securities directly from the Company); or

 

     

     

    

 

(ii)            the
date a majority of the members of the Board is replaced during any 12-month period by directors whose appointment or election is not endorsed
by a majority of the members of the Board before the date of the appointment or election; or

 

(iii)            the
consummation of (A) any consolidation or merger of the Company where the stockholders of the Company, immediately prior to the consolidation
or merger, would not, immediately after the consolidation or merger, beneficially own (as such term is defined in Rule 13d-3 under
the Act), directly or indirectly, shares representing in the aggregate more than fifty (50) percent of the voting shares of the Company
issuing cash or securities in the consolidation or merger (or of its ultimate parent corporation, if any), or (B) any sale or other
transfer (in one transaction or a series of transactions contemplated or arranged by any party as a single plan) of all or substantially
all of the assets of the Company.

 

Notwithstanding the foregoing, a “Change in
Control” shall not be deemed to have occurred for purposes of the foregoing clause (i) solely as the result of an acquisition
of securities by the Company which, by reducing the number of shares of Voting Securities outstanding, increases the proportionate number
of Voting Securities beneficially owned by any person to fifty (50) percent or more of the combined voting power of all of the then outstanding
Voting Securities; provided, however, that if any person referred to in this sentence shall thereafter become the beneficial owner of
any additional shares of Voting Securities (other than pursuant to a stock split, stock dividend, or similar transaction or as a result
of an acquisition of securities directly from the Company) and immediately thereafter beneficially owns fifty (50) percent or more of
the combined voting power of all of the then outstanding Voting Securities, then a “Change in Control” shall be deemed to
have occurred for purposes of the foregoing clause (i).

 

(c)            “Good
Reason” shall mean that you have complied with the Good Reason Process (hereinafter defined) following the occurrence of any of
the following events: (i) a material diminution in your responsibilities, authority or duties; (ii) a diminution in your Base
Salary except for across-the-board salary reductions of similar magnitude based on the Company’s financial performance similarly
affecting all or substantially all senior management employees of the Company; (iii) a material change in the geographic location
of the principal office of the Company to which you are assigned, such that there is an increase of at least thirty (30) miles of driving
distance to such location from your principal residence as of such change; or (iv) the material breach of this Agreement by the Company.

 

(d)            “Good
Reason Process” shall mean that (i) you reasonably determine that a “Good Reason” condition has occurred;
(ii) you notify the Company in writing of the first occurrence of the Good Reason condition within 60 days of the first
occurrence of such condition; (iii) you reasonably cooperate with the Company’s efforts, for a period not less than 30
days following such notice (the “Cure Period”), to remedy the condition; (iv) notwithstanding such efforts,
the Good Reason condition continues to exist; and (v) you terminate your employment within 60 days after the end of the Cure
Period. If the Company cures the Good Reason condition during the Cure Period, Good Reason shall be deemed not to have occurred.

 

     

     

    

 

(e)            “Qualifying
Termination” shall mean, after the Effective Date, the Company terminates your employment without Cause or you resign from your
employment for Good Reason. For the avoidance of doubt, a termination due to your death or disability is not a Qualifying Termination.

 

11.            Continuing
Obligations.

 

(a)            Restrictive
Covenants Agreements. You acknowledge and agree that your Noncompetition and Nonsolicitation Agreement, dated November 1, 2011,
and your Invention and Non-Disclosure Agreement, dated November 1, 2011, as amended, shall continue in full force and effect and
are incorporated by reference herein (together, the “Restrictive Covenants Agreements”). For purposes of this Agreement,
the obligations in this Section 11 and those that arise in the Restrictive Covenants Agreement and any other agreement relating to
confidentiality, assignment of inventions, or other restrictive covenants shall collectively be referred to as the “Continuing
Obligations.”

 

(b)            Third
Party Agreements and Rights. You hereby confirm that you are not bound by the terms of any agreement with any previous employer or
other party which restricts your engagement in any business in any way, other than confidentiality restrictions (if any). You represent
to the Company that your execution of this Agreement, your employment with the Company and the performance of your proposed duties for
the Company will not violate any obligations you may have to any such previous employer or other party. In your work for the Company,
you will not disclose or make use of any information in violation of any agreements with or rights of any such previous employer or other
party, and you will not bring to the premises of the Company any copies or other tangible embodiments of non-public information belonging
to or obtained from any such previous employment or other party. You agree that, notwithstanding anything to the contrary herein, if your
employment ends in connection with or as a result of a former employer or third party enforcing or attempting to enforce a noncompetition
obligation or other restrictive covenant against you, such termination will not constitute a Qualifying Termination for purposes of this
Agreement.

 

(c)            Litigation
and Regulatory Cooperation. During and for the period of six (6) years after your employment with the Company ends, you
shall cooperate in any reasonable manner with the Company in (i) the defense or prosecution of any claims or actions now in
existence or which may be brought in the future against or on behalf of the Company which relate to events or occurrences that
transpired while you were employed by the Company, (ii) the investigation, whether internal or external, of any matters about
which the Company believes you may have knowledge or information and (iii) transitioning your duties. Your cooperation in any
reasonable manner in connection with such claims, actions or investigations shall include, but not be limited to, being available to
meet with counsel to answer questions or to prepare for discovery or trial and to act as a witness on behalf of the Company, all at
mutually convenient times. During and for the period of six (6) years after your employment with the Company ends, you also
shall cooperate in any reasonable manner with the Company in connection with any investigation or review of any federal,
state or local regulatory authority as any such investigation or review relates to events or occurrences that transpired while you
were employed by the Company. The Company shall reimburse you for any reasonable out of pocket expenses incurred in connection with
your performance of obligations pursuant to this Section 11(c) and, after the expiration of the period during which you
are receiving the Severance Amount, shall reimburse you at the last rate of base compensation effective during your employment for
your reasonable time spent providing cooperation, excluding time required to testify in response to subpoena.

 

     

     

    

 

(d)            Relief.
You agree that it would be difficult to measure any damages caused to the Company which might result from your breach of any of the Continuing
Obligations, and that in any event money damages would be an inadequate remedy for any such breach. Accordingly, you agree that if you
breach, or propose to breach, any portion of the Continuing Obligations, the Company shall be entitled, in addition to all other remedies
that it may have, to an injunction or other appropriate equitable relief to restrain any such breach without showing or proving any actual
damage to the Company.

 

12.            Section 409A

 

(a)            Anything
in this Agreement to the contrary notwithstanding, if at the time of your separation from service within the meaning of Section 409A
of the Code, the Company determines that you are a “specified employee” within the meaning of Section 409A(a)(2)(B)(i) of
the Code, then to the extent any payment or benefit that you become entitled to under this Agreement or otherwise on account of your separation
from service would be considered deferred compensation otherwise subject to the 20 percent additional tax imposed pursuant to Section 409A(a) of
the Code as a result of the application of Section 409A(a)(2)(B)(i) of the Code, such payment shall not be payable and such
benefit shall not be provided until the date that is the earlier of (A) six months and one day after your separation from service,
or (B) your death. If any such delayed cash payment is otherwise payable on an installment basis, the first payment shall include
a catch-up payment covering amounts that would otherwise have been paid during the six-month period but for the application of this provision,
and the balance of the installments shall be payable in accordance with their original schedule.

 

(b)            All
in-kind benefits provided and expenses eligible for reimbursement under this Agreement shall be provided by the Company or incurred by
you during the time periods set forth in this Agreement. All reimbursements shall be paid as soon as administratively practicable, but
in no event shall any reimbursement be paid after the last day of the taxable year following the taxable year in which the expense was
incurred. The amount of in-kind benefits provided or reimbursable expenses incurred in one taxable year shall not affect the in-kind benefits
to be provided or the expenses eligible for reimbursement in any other taxable year (except for any lifetime or other aggregate limitation
applicable to medical expenses). Such right to reimbursement or in-kind benefits is not subject to liquidation or exchange for another
benefit.

 

(c)            To
the extent that any payment or benefit described in this Agreement constitutes “non-qualified deferred compensation”
under Section 409A of the Code, and to the extent that such payment or benefit is payable upon the termination of your
employment, then such payments or benefits shall be payable only upon your “separation from service.” The
determination of whether and when a separation from service has occurred shall be made in accordance with the presumptions set forth
in Treasury Regulation Section 1.409A 1(h).

 

     

     

    

 

(d)            The
parties intend that this Agreement will be administered in accordance with Section 409A of the Code. To the extent that any provision
of this Agreement is ambiguous as to its compliance with Section 409A of the Code, the provision shall be read in such a manner so
that all payments hereunder comply with Section 409A of the Code. Each payment pursuant to this Agreement is intended to constitute
a separate payment for purposes of Treasury Regulation Section 1.409A 2(b)(2). The parties agree that this Agreement may be amended,
as reasonably requested by either party, and as may be necessary to fully comply with Section 409A of the Code and all related rules and
regulations in order to preserve the payments and benefits provided hereunder without additional cost to either party.

 

(e)            The
Company makes no representation or warranty and shall have no liability to you or any other person if any provisions of this Agreement
are determined to constitute deferred compensation subject to Section 409A of the Code but do not satisfy an exemption from, or the
conditions of, such Section.

 

13.            Withholding;
Tax Effect. All forms of compensation referred to in this Agreement are subject to reduction to reflect applicable withholding and
payroll taxes and other deductions required by law. You hereby acknowledge that the Company does not have a duty to design its compensation
policies in a manner that minimizes your tax liabilities, and you will not make any claim against the Company or the Board related to
tax liabilities arising from your compensation.

 

14.            Entire
Agreement. This Agreement, together with the Restrictive Covenants Agreements and any existing stock option or incentive stock agreements
or similar, constitute the complete agreement between you and the Company, contains all of the terms of your employment with the Company
and supersedes any prior agreements, representations or understandings (whether written, oral or implied) between you and the Company.

 

15.            Governing
Law; Jurisdiction. This Agreement will be governed by the laws of the Commonwealth of Massachusetts, excluding laws relating to conflicts
or choice of law. You and the Company each submit to the exclusive personal jurisdiction of the federal and state courts located in the
Commonwealth of Massachusetts.

 

16.            Assignment;
Successors and Assigns. Neither you nor the Company may make any assignment of this Agreement or any interest in it, by
operation of law or otherwise, without the prior written consent of the other; provided, however, that the Company may assign its
rights and obligations under this Agreement without your consent to any affiliate or to any person or entity with whom the Company
shall hereafter effect a reorganization, consolidate with, or merge into or to whom it transfers all or substantially all of its
properties or assets; provided further, that if you remain employed or become employed by the Company, the purchaser or any of their
affiliates in connection with any such transaction, then you shall not be entitled to any severance payments or benefits solely as a
result of such transaction. This Agreement shall inure to the benefit of and be binding upon you and the Company, and each of your
and its respective successors, executors, administrators, heirs and permitted assigns. In the event of your death after the Date of
Termination but prior to the completion by the Company of all payments due to you under this Agreement, the Company shall continue
such payments to your beneficiary designated in writing to the Company prior to your death (or to your estate, if you fail to make
such designation).

 

     

     

    

 

17.            Waiver;
Amendment. No waiver of any provision hereof shall be effective unless made in writing and signed by the waiving party. The failure
of any party to require the performance of any term or obligation of this Agreement, or the waiver by any party of any breach of this
Agreement, shall not prevent any subsequent enforcement of such term or obligation or be deemed a waiver of any subsequent breach. This
Agreement may be amended or modified only by a written instrument signed by you and by a member of the Board.

 

18.            Enforceability.
If any portion or provision of this Agreement (including, without limitation, any portion or provision of any section of this Agreement)
shall to any extent be declared illegal or unenforceable by a court of competent jurisdiction, then the remainder of this Agreement, or
the application of such portion or provision in circumstances other than those as to which it is so declared illegal or unenforceable,
shall not be affected thereby, and each portion and provision of this Agreement shall be valid and enforceable to the fullest extent permitted
by law.

 

19.            Indemnification/Other
Terms. The Company agrees to indemnify you to the fullest extent required by the laws of the State of Delaware, the Company’s
Articles of Incorporation and Bylaws, and in accordance with its Directors and Officers Liability Policy. The provisions of this Agreement
shall survive the termination of your employment to the extent necessary to effectuate the terms contained herein. The headings and other
captions in this Agreement are for convenience and reference only and shall not be used in interpreting, construing or enforcing any of
the provisions of this Agreement. This Agreement may be executed in separate counterparts. When both counterparts are signed, they shall
be treated together as one and the same document. PDF copies of signed counterparts shall be equally effective as originals.

Re:       Employment
Agreement

 

Dear David:

 

On behalf of Gelesis, Inc. (the “Company”), I
am pleased to confirm our offer to continue your employment as the Company’s Chief Operating and Commercial Officer (“COCO”).
  The terms and conditions of your continued employment are set forth below in this letter agreement (the “Agreement”):

 

1.            Position.
As COCO, you will report to the Company’s Chief Executive Officer (the “CEO”) and have such powers and duties as may
from time to time be prescribed by the CEO. This is a full-time employment position. It is understood and agreed that, while you render
services to the Company, you will not engage in any other employment, consulting or other business activities (whether full-time or part-time),
except as expressly authorized in writing by the CEO. Notwithstanding the foregoing, you may engage in religious, charitable and other
community activities so long as such activities do not interfere or conflict with your obligations to the Company.

 

2.            Effective
Date. The Effective Date of this Agreement shall be on the closing of the currently contemplated deSPAC transaction with Capstar Special
Purpose Acquisition Corp (or other entity) (“Effective Date”).

 

3.            Compensation
and Related Matters.

 

(a)            Base
Salary. The Company will pay you an initial base salary at the rate of $370,800 per year, payable in accordance with the Company’s
standard payroll schedule for its executives and subject to applicable deductions and withholdings. Your base salary will be subject to
periodic increases at the Company’s discretion. Your base salary in effect at any given time is referred to herein as the “Base
Salary.”

 

(b)            Annual
Bonus. You will initially be eligible to receive an annual performance bonus targeted at 40% of your Base Salary. The actual bonus
amount is discretionary and will be determined by the Company’s Board of Directors. To receive an annual bonus, you must be employed
by the Company as of December 31 of the year to which such bonus relates. Any annual bonus will be paid no later than March 15th
of the calendar year following the calendar year to which such bonus relates.

 

(c)            Expenses.
The Company will promptly reimburse you for all reasonable expenses incurred by you in performing services hereunder, in accordance with
the policies and procedures then in effect and established by the Company for its executives.

 

     

     

    

 

(d)            Benefits/Paid
Time Off. You will be eligible, subject to the terms of the applicable plans and programs, to participate in the employee benefits
and insurance programs generally made available to the Company’s full-time employees. You will be entitled to 20 days annually of
paid time off consistent with the terms of the Company’s paid time off policy for its executives, as in effect from time to time.
The Company reserves the right to modify, amend or cancel any of its benefits plans or programs at any time.

 

4.            Equity.
All options that you were previously granted to purchase the Company’s Common Stock shall continue to vest in accordance with your
Stock Option Agreements with the Company and the Gelesis 2006 Stock Incentive Plan, as amended, and the 2016 Stock Incentive Plan, as
amended as applicable.

 

5.            Location.
You will primarily work from the Company’s U.S. office, currently located in Boston, Massachusetts, provided, however, that you
may be required to travel on business as is necessary from time to time.

 

6.            At-Will
Employment; Date of Termination. At all times your employment is “at will,” meaning you or the Company may terminate it
at any time for any or no reason, subject to the terms of this Agreement. Your last day of employment regardless of the reason is referred
to herein as the “Date of Termination.” Given your role as a senior executive, in the event that you elect to end your
employment other than for Good Reason, the Company requires you to provide at least 30 days’ advance written notice to the Company.
Notwithstanding the foregoing, in the event you give such advance written notice, the Company may unilaterally accelerate the Date of
Termination, and such acceleration shall not result in a termination by the Company for purposes of this Agreement.

 

To the extent applicable, you shall be deemed to have resigned from
all officer and board member positions that you hold with the Company or any of its respective subsidiaries and affiliates upon the termination
of your employment regardless of the reason. You shall execute any documents in reasonable form as may be requested to confirm or effectuate
any such resignations.

 

7.            Accrued
Obligations. In the event of the ending of your employment regardless of the reason, the Company shall pay you (i) your Base
Salary and, if applicable, any accrued but unused vacation, through the Date of Termination, (ii) the amount of any documented expenses
properly incurred by you on behalf of the Company prior to any such termination and not yet reimbursed, and (iii) the awarded, but
unpaid portion, if any, of the annual performance bonus for any prior year (the “Accrued Obligations”).

 

8.            Severance
Pay and Benefits Upon a Qualifying Termination. In the event that a Qualifying Termination (as defined in Section 10)
occurs, then, in addition to you being entitled to the Accrued Obligations, and subject to (i) you signing a separation
agreement and release in a form and manner reasonably satisfactory to the Company, which shall include, without limitation, a
general release of claims against the Company and all related persons and entities and a reaffirmation of the Continuing Obligations
(as defined below) and, in the Company’s discretion, a one year post-employment noncompetition agreement that is no more
restrictive than the existing Non-Competition and Non-Solicitation Agreement, and shall provide that if you breach the
Continuing Obligations, all payments of the Severance Amount (as defined below) shall immediately cease (the “Separation
Agreement”), and (ii) the Separation Agreement becoming irrevocable, all within 60 days after the Date of Termination
(or such shorter period as set forth in the Separation Agreement):

 

(a)            the
Company shall pay you an amount equal to twelve (12) months of your Base Salary (the “Severance Amount”); and

 

(b)            subject
to your copayment of premium amounts at the applicable active employees’ rate and your proper election to receive benefits under
the Consolidated Omnibus Budget Reconciliation Act of 1985, as amended (“COBRA”), the Company shall pay to the group
health plan provider(s) or the COBRA provider a monthly payment equal to the monthly employer contribution that the Company would
have made to provide health insurance to you if you had remained employed by the Company until the earliest of (A) the twelve (6) month
anniversary of the Date of Termination; (B) your eligibility for group health plan benefits under any other employer’s group
health plan; or (C) the cessation of your continuation rights under COBRA; provided, however, that if the Company reasonably determines
that it cannot pay such amounts to the group health plan provider(s) or the COBRA provider (if applicable) without potentially violating
applicable law (including, without limitation, Section 2716 of the Public Health Service Act), then the Company shall convert such
payments to payroll payments directly to you for the time period specified above. Such payments, if to you, shall be subject to tax-related
deductions and withholdings and paid on the Company’s regular payroll dates.

 

     

     

    

 

The amounts payable under this Section 8, to the extent taxable,
shall be paid out in substantially equal installments in accordance with the Company’s payroll practice over twelve (12) months
commencing within 60 days after the Date of Termination; provided, however, that if the 60-day period begins in one calendar year and
ends in a second calendar year, the Severance Amount, to the extent it qualifies as “non-qualified deferred compensation”
within the meaning of Section 409A of the Internal Revenue Code of 1986, as amended (the “Code”), shall begin
to be paid in the second calendar year by the last day of such 60-day period; provided, further, that the initial payment shall include
a catch-up payment to cover amounts retroactive to the day immediately following the Date of Termination. Each payment pursuant to this
Agreement is intended to constitute a separate payment for purposes of Treasury Regulation Section 1.409A-2(b)(2).

 

If your employment ends for any reason other than a Qualifying Termination,
you will be entitled to the Accrued Obligations and will not be entitled to any further compensation from the Company. For the avoidance
of doubt, if your employment ends due to your death or disability, you will receive the Accrued Obligations but will not be eligible for
severance pay and benefits, whether pursuant to this Section 8 or otherwise.

 

9.            Change
in Control Payment. The provisions of this Section 9 address your rights and obligations upon the occurrence of a Change in
Control of the Company. These provisions shall supplement, and be in addition to the provisions of Section 8 regarding
severance pay and benefits upon a termination of employment, if such termination of employment occurs within twelve (12) months
after the occurrence of the first event constituting a Change in Control. These provisions shall terminate and be of no
further force or effect beginning twelve (12) months after the occurrence of a Change in Control.

 

     

     

    

 

(a)            Change
in Control. If your employment is terminated by the Company without Cause or by you for Good Reason within twelve (12) months after a
Change in Control, then, subject to your signing of the Separation Agreement and the Separation Agreement becoming irrevocable, all within
60 days after the Date of Termination, notwithstanding anything to the contrary in any applicable option agreement or stock-based award
agreement, all unvested stock options and other unvested stock-based awards held by you shall immediately accelerate and become fully
exercisable or nonforfeitable as of the Date of Termination.

 

10.            Definitions.
For the purposes of this Agreement, the following terms shall have the following meanings:

 

(a)            “Cause”
shall mean (i) your dishonest statements or acts with respect to the Company or any affiliate of the Company, or any current or prospective
customers, suppliers, vendors or other third parties with which such entity does business that results in or is reasonably anticipated
to result in harm to the Company; (ii) your commission of (A) a felony or (B) any misdemeanor involving moral turpitude,
deceit, dishonesty or fraud; (iii) your failure to perform your assigned duties and responsibilities, which failure continues, in
the reasonable judgment of the Board, for 30 days after written notice given to you describing such failure; (iv) your gross negligence,
willful misconduct or insubordination that results in or is reasonably anticipated to result in harm to the Company; (v) your violation
of any material provision of any agreement(s) between you and the Company or any Company policies including, without limitation,
this Agreement, the Restrictive Covenants Agreement, agreements relating to noncompetition, nonsolicitation, nondisclosure and/or assignment
of inventions or policies related to ethics or workplace conduct; or (vi) your failure to cooperate with a bona fide internal investigation
or an investigation by regulatory or law enforcement authorities, after being instructed by the Board to cooperate, or the willful destruction
or failure to preserve documents or other materials known to be relevant to such investigation or the inducement of others to fail to
cooperate or to produce documents or other materials in connection with such investigation.

 

(b)            “Change
of Control” shall mean any of the following:

 

(i)            any
 “person,” as such term is used in Sections 13(d) and 14(d) of the Securities Exchange Act of 1934, as amended (the
 “Act”) (other than the Company, any of its subsidiaries, or any trustee, fiduciary or other person or entity holding securities
under any employee benefit plan or trust of the Company or any of its subsidiaries), together with all “affiliates” and “associates”
(as such terms are defined in Rule 12b-2 under the Act) of such person, shall become the “beneficial owner” (as such
term is defined in Rule 13d-3 under the Act), directly or indirectly, of securities of the Company representing fifty (50) percent
or more of the combined voting power of the Company’s then outstanding securities having the right to vote in an election of the
Board (“Voting Securities”) (in such case other than as a result of an acquisition of securities directly from the Company);
or

 

(ii)            the
date a majority of the members of the Board is replaced during any 12-month period by directors whose appointment or election is not endorsed
by a majority of the members of the Board before the date of the appointment or election; or

 

(iii)            the
consummation of (A) any consolidation or merger of the Company where the stockholders of the Company, immediately prior to the consolidation
or merger, would not, immediately after the consolidation or merger, beneficially own (as such term is defined in Rule 13d-3 under
the Act), directly or indirectly, shares representing in the aggregate more than fifty (50) percent of the voting shares of the Company
issuing cash or securities in the consolidation or merger (or of its ultimate parent corporation, if any), or (B) any sale or other
transfer (in one transaction or a series of transactions contemplated or arranged by any party as a single plan) of all or substantially
all of the assets of the Company.

 

     

     

    

 

Notwithstanding the foregoing, a “Change in
Control” shall not be deemed to have occurred for purposes of the foregoing clause (i) solely as the result of an acquisition
of securities by the Company which, by reducing the number of shares of Voting Securities outstanding, increases the proportionate number
of Voting Securities beneficially owned by any person to fifty (50) percent or more of the combined voting power of all of the then outstanding
Voting Securities; provided, however, that if any person referred to in this sentence shall thereafter become the beneficial owner of
any additional shares of Voting Securities (other than pursuant to a stock split, stock dividend, or similar transaction or as a result
of an acquisition of securities directly from the Company) and immediately thereafter beneficially owns fifty (50) percent or more of
the combined voting power of all of the then outstanding Voting Securities, then a “Change in Control” shall be deemed to
have occurred for purposes of the foregoing clause (i).

 

(c)            “Good
Reason” shall mean that you have complied with the Good Reason Process (hereinafter defined) following the occurrence of any of
the following events: (i) a material diminution in your responsibilities, authority or duties; (ii) a diminution in your Base
Salary except for across-the-board salary reductions of similar magnitude based on the Company’s financial performance similarly
affecting all or substantially all senior management employees of the Company; (iii) a material change in the geographic location
of the principal office of the Company to which you are assigned, such that there is an increase of at least thirty (30) miles of driving
distance to such location from your principal residence as of such change; or (iv) the material breach of this Agreement by the Company.

 

(d)            “Good
Reason Process” shall mean that (i) you reasonably determine that a “Good Reason” condition has occurred; (ii) you
notify the Company in writing of the first occurrence of the Good Reason condition within 60 days of the first occurrence of such condition;
(iii) you reasonably cooperate with the Company’s efforts, for a period not less than 30 days following such notice (the “Cure
Period”), to remedy the condition; (iv) notwithstanding such efforts, the Good Reason condition continues to exist; and
(v) you terminate your employment within 60 days after the end of the Cure Period. If the Company cures the Good Reason condition
during the Cure Period, Good Reason shall be deemed not to have occurred.

 

     

     

    

 

(e)            “Qualifying
Termination” shall mean, after the Effective Date, the Company terminates your employment without Cause or you resign from your
employment for Good Reason. For the avoidance of doubt, a termination due to your death or disability is not a Qualifying Termination.

 

11.            Continuing
Obligations.

 

(a)            Restrictive
Covenants Agreements. You acknowledge and agree that your Noncompetition and Nonsolicitation Agreement, dated September 1, 2016,
and your Invention and Non-Disclosure Agreement, dated September 1, 2016, as amended, shall continue in full force and effect, and
are incorporated by reference herein (together, the “Restrictive Covenants Agreements”). For purposes of this Agreement,
the obligations in this Section 11 and those that arise in the Restrictive Covenants Agreement and any other agreement relating to
confidentiality, assignment of inventions, or other restrictive covenants shall collectively be referred to as the “Continuing
Obligations.”

 

(b)            Third
Party Agreements and Rights. You hereby confirm that you are not bound by the terms of any agreement with any previous employer or
other party which restricts your engagement in any business in any way, other than confidentiality restrictions (if any). You represent
to the Company that your execution of this Agreement, your employment with the Company and the performance of your proposed duties for
the Company will not violate any obligations you may have to any such previous employer or other party. In your work for the Company,
you will not disclose or make use of any information in violation of any agreements with or rights of any such previous employer or other
party, and you will not bring to the premises of the Company any copies or other tangible embodiments of non-public information belonging
to or obtained from any such previous employment or other party. You agree that, notwithstanding anything to the contrary herein, if your
employment ends in connection with or as a result of a former employer or third party enforcing or attempting to enforce a noncompetition
obligation or other restrictive covenant against you, such termination will not constitute a Qualifying Termination for purposes of this
Agreement.

 

(c)            Litigation
and Regulatory Cooperation. During and for the period of six (6) years after your employment with the Company ends, you
shall cooperate in any reasonable manner with the Company in (i) the defense or prosecution of any claims or actions now in
existence or which may be brought in the future against or on behalf of the Company which relate to events or occurrences that
transpired while you were employed by the Company, (ii) the investigation, whether internal or external, of any matters about
which the Company believes you may have knowledge or information and (iii) transitioning your duties. Your cooperation in any
reasonable manner in connection with such claims, actions or investigations shall include, but not be limited to, being available to
meet with counsel to answer questions or to prepare for discovery or trial and to act as a witness on behalf of the Company, all at
mutually convenient times. During and for the period of six (6) years after your employment with the Company ends, you also
shall cooperate in any reasonable manner with the Company in connection with any investigation or review of any federal, state or
local regulatory authority as any such investigation or review relates to events or occurrences that transpired while you were
employed by the Company. The Company shall reimburse you for any reasonable out of pocket expenses incurred in connection
with your performance of obligations pursuant to this Section 11(c), and, after the expiration of the period during which you
are receiving the Severance Amount, shall reimburse you at the last rate of base compensation effective during your employment for
your reasonable time spent providing cooperation, excluding time required to testify in response to subpoena.

 

     

     

    

 

(d)            Relief.
You agree that it would be difficult to measure any damages caused to the Company which might result from your breach of any of the Continuing
Obligations, and that in any event money damages would be an inadequate remedy for any such breach. Accordingly, you agree that if you
breach, or propose to breach, any portion of the Continuing Obligations, the Company shall be entitled, in addition to all other remedies
that it may have, to an injunction or other appropriate equitable relief to restrain any such breach without showing or proving any actual
damage to the Company.

 

12.            Section 409A

 

(a)            Anything
in this Agreement to the contrary notwithstanding, if at the time of your separation from service within the meaning of Section 409A
of the Code, the Company determines that you are a “specified employee” within the meaning of Section 409A(a)(2)(B)(i) of
the Code, then to the extent any payment or benefit that you become entitled to under this Agreement or otherwise on account of your separation
from service would be considered deferred compensation otherwise subject to the 20 percent additional tax imposed pursuant to Section 409A(a) of
the Code as a result of the application of Section 409A(a)(2)(B)(i) of the Code, such payment shall not be payable and such
benefit shall not be provided until the date that is the earlier of (A) six months and one day after your separation from service,
or (B) your death. If any such delayed cash payment is otherwise payable on an installment basis, the first payment shall include
a catch-up payment covering amounts that would otherwise have been paid during the six-month period but for the application of this provision,
and the balance of the installments shall be payable in accordance with their original schedule.

 

(b)            All
in-kind benefits provided and expenses eligible for reimbursement under this Agreement shall be provided by the Company or incurred by
you during the time periods set forth in this Agreement. All reimbursements shall be paid as soon as administratively practicable, but
in no event shall any reimbursement be paid after the last day of the taxable year following the taxable year in which the expense was
incurred. The amount of in-kind benefits provided or reimbursable expenses incurred in one taxable year shall not affect the in-kind benefits
to be provided or the expenses eligible for reimbursement in any other taxable year (except for any lifetime or other aggregate limitation
applicable to medical expenses). Such right to reimbursement or in-kind benefits is not subject to liquidation or exchange for another
benefit.

 

(c)            To
the extent that any payment or benefit described in this Agreement constitutes “non-qualified deferred compensation” under
Section 409A of the Code, and to the extent that such payment or benefit is payable upon the termination of your employment, then
such payments or benefits shall be payable only upon your “separation from service.” The determination of whether and when
a separation from service has occurred shall be made in accordance with the presumptions set forth in Treasury Regulation Section 1.409A
1(h).

 

     

     

    

 

(d)            The
parties intend that this Agreement will be administered in accordance with Section 409A of the Code. To the extent that any provision
of this Agreement is ambiguous as to its compliance with Section 409A of the Code, the provision shall be read in such a manner so
that all payments hereunder comply with Section 409A of the Code. Each payment pursuant to this Agreement is intended to constitute
a separate payment for purposes of Treasury Regulation Section 1.409A 2(b)(2). The parties agree that this Agreement may be amended,
as reasonably requested by either party, and as may be necessary to fully comply with Section 409A of the Code and all related rules and
regulations in order to preserve the payments and benefits provided hereunder without additional cost to either party.

 

(e)            The
Company makes no representation or warranty and shall have no liability to you or any other person if any provisions of this Agreement
are determined to constitute deferred compensation subject to Section 409A of the Code but do not satisfy an exemption from, or the
conditions of, such Section.

 

13.            Withholding;
Tax Effect. All forms of compensation referred to in this Agreement are subject to reduction to reflect applicable withholding and
payroll taxes and other deductions required by law. You hereby acknowledge that the Company does not have a duty to design its compensation
policies in a manner that minimizes your tax liabilities, and you will not make any claim against the Company or the Board related to
tax liabilities arising from your compensation.

 

14.            Entire
Agreement. This Agreement, together with the Restrictive Covenants Agreements, and any existing stock option or incentive stock agreements,
or similar, constitute the complete agreement between you and the Company, contains all of the terms of your employment with the Company
and supersedes any prior agreements, representations or understandings (whether written, oral or implied) between you and the Company.

 

15.            Governing
Law; Jurisdiction. This Agreement will be governed by the laws of the Commonwealth of Massachusetts, excluding laws relating to conflicts
or choice of law. You and the Company each submit to the exclusive personal jurisdiction of the federal and state courts located in the
Commonwealth of Massachusetts.

 

16.            Assignment;
Successors and Assigns. Neither you nor the Company may make any assignment of this Agreement or any interest in it, by
operation of law or otherwise, without the prior written consent of the other; provided, however, that the Company may assign its
rights and obligations under this Agreement without your consent to any affiliate or to any person or entity with whom the Company
shall hereafter effect a reorganization, consolidate with, or merge into or to whom it transfers all or substantially all of its
properties or assets; provided further, that if you remain employed or become employed by the Company, the purchaser or any of their
affiliates in connection with any such transaction, then you shall not be entitled to any severance payments or benefits solely as a
result of such transaction. This Agreement shall inure to the benefit of and be binding upon you and the Company, and each of your
and its respective successors, executors, administrators, heirs and permitted assigns. In the event of your death after the Date of
Termination but prior to the completion by the Company of all payments due to you under this Agreement, the Company shall continue
such payments to your beneficiary designated in writing to the Company prior to your death (or to your estate, if you fail to
make such designation).

 

     

     

    

 

17.            Waiver;
Amendment. No waiver of any provision hereof shall be effective unless made in writing and signed by the waiving party. The failure
of any party to require the performance of any term or obligation of this Agreement, or the waiver by any party of any breach of this
Agreement, shall not prevent any subsequent enforcement of such term or obligation or be deemed a waiver of any subsequent breach. This
Agreement may be amended or modified only by a written instrument signed by you and the CEO.

 

18.            Enforceability.
If any portion or provision of this Agreement (including, without limitation, any portion or provision of any section of this Agreement)
shall to any extent be declared illegal or unenforceable by a court of competent jurisdiction, then the remainder of this Agreement, or
the application of such portion or provision in circumstances other than those as to which it is so declared illegal or unenforceable,
shall not be affected thereby, and each portion and provision of this Agreement shall be valid and enforceable to the fullest extent permitted
by law.

 

19.            Indemnification/Other
Terms. The Company agrees to indemnify you to the fullest extent required by the laws of the State of Delaware, the Company’s
Articles of Incorporation and Bylaws (as each may be amended and/or restated from time to time), and in accordance with its Directors
and Officers Liability Policy. The provisions of this Agreement shall survive the termination of your employment to the extent necessary
to effectuate the terms contained herein. The headings and other captions in this Agreement are for convenience and reference only and
shall not be used in interpreting, construing or enforcing any of the provisions of this Agreement. This Agreement may be executed in
separate counterparts. When both counterparts are signed, they shall be treated together as one and the same document. PDF copies of signed
counterparts shall be equally effective as originals.
