Re:    Separation Agreement
Dear Tom:
This Separation Agreement constitutes notice, including, but not limited to
notice under Section 10(d) of your Executive Employment Agreement dated December
23, 2014, as amended on May 27, 2015 and January 8, 2018 (“Employment
Agreement”), that your employment with Flex Pharma Inc. (along with its
affiliates, the “Company”) will terminate on June 26, 2018. This Separation
Agreement sets forth the understanding between you and the Company relating to
the termination of your employment with the Company effective on June 26, 2018.
We hope to make the transition as smooth as possible.

Notwithstanding any provisions herein, this Agreement supersedes any and all
prior agreements between you and the Company, including, but not limited to,
your Employment Agreement; provided, however, that your Employee
Non-Solicitation, Non-Competition, Confidential Information and Inventions
Assignment Agreement (“Confidentiality Agreement”) that you signed as a
condition of your employment, which is attached hereto as Exhibit B, shall
continue in full force and effect and is expressly incorporated by reference
herein.

In the interest of clarity, regardless of whether you enter into this Agreement,
the following terms shall apply in connection with the ending of your
employment: (i) the Company will pay you your base salary earned through the
Separation Date (as defined below), as well as any accrued but unused PTO
through the Separation Date, subject to standard deductions and withholdings;
(ii) your current coverage under the Company’s group health insurance plans will
cease as of the Separation Date; (iii) if you are currently participating in the
Company’s group health insurance plans, you may be eligible to continue your
group health insurance benefits at your own expense to the extent provided by
the federal COBRA law and/or state law and the Company’s current group health
insurance policies, and, later, you may be able to convert to an individual
policy through the provider of the Company’s health insurance, if you wish; (iv)
the terms of any continuation of health insurance coverage under the law will be
set forth in a separate written notice; and (v) your eligibility to participate
in any other employee benefit plans and programs of the Company will cease on
the Separation Date in accordance with the applicable benefit plan or program
terms; and (vi) any unvested stock will terminate on your Separation Date, and
any vested stock will continue to be subject to the terms of any and all
applicable plans, awards, grants and/or agreements. Also, regardless of whether
you sign this Agreement and/or receive the Severance Payments, you remain

--------------------------------------------------------------------------------

bound by your continuing obligations under the Confidentiality Agreement, which
is intended to, and does, survive the termination of this Agreement.
With those understandings, you and the Company agree as follows:
1.
Transition Period Payments And Benefits

Provided that you enter into and comply with this Agreement, including the
Release of Claims in Section 4 below, you will continue to receive your base
salary at the rate in effect as of the date hereof and your benefits at the same
level in effect as of the date hereof, and said base salary and benefits shall
continue during the Transition Period and until (and including) your Separation
Date. For purposes of this Agreement, the actual last day of your employment
shall be referred to as the “Separation Date,” and the time period between the
date of this Agreement and the Separation Date shall be referred to as the
“Transition Period.”
During the Transition Period, you shall perform your responsibilities to the
Company satisfactorily and as required by the Company, and to otherwise fulfill
your duties and obligations as set forth herein.

2.
Severance Payments

Provided that you enter into and comply with this Agreement, including the
Release of Claims in Section 4 below and the Release of Claims attached to this
Agreement as Exhibit A, and provide a resignation of all offices, directorships
and fiduciary positions with the Company, its affiliates and employee benefit
plans as of the Separation Date (pursuant to section 12(c) of your Employment
Agreement), the Company will provide the following severance payments to you:

(a)
The Company will pay you a lump sum payment of two hundred fifty-seven thousand,
two hundred fifty dollars ($257,250.00) which is equivalent to nine (9) months
of your base pay (“Lump Sum Payment”).  The Company may deduct from the Lump Sum
Payment any required withholding taxes, government payments and benefit
premium contributions. Notwithstanding any language to the contrary, no Lump Sum
Payment shall be made until the first regularly scheduled payroll date following
your execution and non-revocation of this Agreement and the Release of Claims in
Exhibit A; provided, however, that you shall execute the Release of Claims in
Exhibit A no earlier than the Separation Date. You agree that this Lump Sum
Payment is above and beyond any payments otherwise owed to you under the terms
of your employment and Employment Agreement, and not required by law.

(b)
In addition, if you timely elect continued coverage under COBRA for yourself and
your covered dependents under the Company’s group health plans, then the Company
shall pay that employer portion of the COBRA premiums that it was paying prior
to the Separation Date in order to continue your health insurance coverage in
effect for yourself (and your covered dependents) on the Separation Date until
the earliest of: (i) the last day of the ninth month after your Separation Date;
(ii) the date when you become eligible for substantially equivalent health
insurance coverage in connection with new employment or self-employment; or
(iii) the date you cease to be eligible for COBRA continuation coverage for any
reason, including plan termination (such period from the termination date
through the earlier of (i)-(iii), the “COBRA Payment Period”). Notwithstanding
the foregoing, if at any time the Company determines that its payment of COBRA
premiums on your behalf would result in a violation of applicable law (including
but not limited to the 2010 Patient Protection and Affordable Care Act, as
amended by the 2010 Health Care and Education Reconciliation Act), then in lieu
of paying COBRA

--------------------------------------------------------------------------------

premiums pursuant to this Section, the Company shall pay you on the last day of
each remaining month of the COBRA Payment Period, a fully taxable cash payment
equal to the COBRA premium for such month, subject to applicable tax withholding
(such amount, the “Special Severance Payment”). Nothing in this Agreement shall
deprive you of your rights under COBRA or ERISA for benefits under plans and
policies arising under your employment by the Company.

Except as expressly provided in this Agreement, and except as to any vested
right that you may have under the express terms of any written benefit plan, by
signing this Agreement you agree that the payments and benefits set forth herein
will be complete and unconditional payment, settlement, accord and/or
satisfaction with respect to your Employment Agreement and all other obligations
and liabilities of the Company to you, including, without limitation, all claims
for back wages, salary, vacation pay, incentive pay, bonuses, stock and stock
options, commissions, severance pay, reimbursement of expenses, any and all
other forms of compensation or benefits, attorney's fees, or other costs or
sums. You acknowledge that, except as provided in this Agreement, you will not
receive any additional compensation, severance, payments or benefits after the
Separation Date, with the exception of any vested right you may have under the
express terms of a written ERISA-qualified benefit plan (e.g., 401k account).
3.
Stock Options

You were granted options to purchase shares of the common stock of Flex Pharma,
Inc. (“Flex Pharma”) pursuant to the Flex Pharma’s 2015 Equity Incentive Plan
(the “Plan”) and one or more Stock Option Grant Notice and Option Agreements
(the “Option Agreements”). Following the Separation Date, vesting of your stock
options will cease and your rights to exercise your options as to any vested
shares will be as set forth in the Plan and Option Agreements and as amended by
the Advisor Agreement entered into by the parties that is effective on June 26,
2018. Any unvested stock options will immediately be cancelled in accordance
with the Plan terms.
4.
Return of Property

By signing below, you certify that you will return to the Company by the
Separation Date all Company property, including, without limitation, files,
notes, passwords, passcodes, software, drawings, records, business plans and
forecasts, financial information, specifications, computer-recorded information,
tangible property (computer equipment, laptops, keys and access cards,
identification badges, credit cards, cell phone) and any documents (including
computerized data and any copies made of any computerized data or software)
containing or embodying information concerning the Company, its business or its
business relationships (in the latter two cases, actual or prospective),
provided you may retain certain non-confidential personnel and benefits
documents that related to your employment. Please coordinate the return of
Company property with Lauren Mastrocola, Controller. Receipt of the Severance
and Retention Payments as described in this Agreement is expressly conditioned
on return of all Company property. After you return all such property, you
commit to deleting and finally purging any duplicates of files or documents that
may contain Company information from any non-Company computer or other device
that remains in your possession after the Separation Date. If you later discover
that you continue to retain any of the Company’s property or information, you
shall return it to the Company immediately.

--------------------------------------------------------------------------------

Exhibit B

EMPLOYEE NON-SOLICITATION, NON-COMPETITION, CONFIDENTIAL INFORMATION AND
INVENTIONS ASSIGNMENT AGREEMENT
In consideration of my employment or continued employment by Flex Pharma, Inc.,
a Delaware corporation (“Company”), and the compensation paid to me now and
during my employment with the Company, I agree to the terms of this Agreement as
follows:
1.
Confidential Information Protections.

1.1     Nondisclosure; Recognition of Company’s Rights. At all times during and
after my employment, I will hold in confidence and will not disclose, use,
lecture upon, or publish any of Company’s Confidential Information (defined
below), except as may be required in connection with my work for Company, or as
expressly authorized by the Chief Executive Officer (the “CEO”) of Company. I
will obtain the CEO’s written approval before publishing or submitting for
publication any material (written, oral, or otherwise) that relates to my work
at Company and/or incorporates any Confidential Information. I hereby assign to
Company any rights I may have or acquire in any and all Confidential Information
and recognize that all Confidential Information shall be the sole and exclusive
property of Company and its assigns.

1.2     Confidential Information. The term “Confidential Information” shall mean
any and all confidential knowledge, data or information related to Company’s
business or its actual or demonstrably anticipated research or development,
including without limitation (a) gene sequences, cell lines, samples, chemical
compounds, assays, biological materials, trade secrets, inventions, ideas,
processes, data, formulae, other works of authorship, know-how, improvements,
discoveries, developments, designs, and techniques; (b) information regarding
products, services, plans for research and development, marketing and business
plans, budgets, financial statements, contracts, prices, suppliers, and
customers; (c) information regarding the skills and compensation of Company’s
employees, contractors, and any other service providers of Company; and (d) the
existence of any business discussions, negotiations, or agreements between
Company and any third party.

1.3     Third Party Information. I understand that Company has received and in
the future will receive from third parties confidential or proprietary
information (“Third Party Information”) subject to a duty on Company’s part to
maintain the confidentiality of such information and to use it only for certain
limited purposes. During and after the term of my employment, I will hold Third
Party Information in strict confidence and will not disclose to anyone (other
than Company personnel who need to know such information in connection with
their work for Company) or use, Third Party Information, except in connection
with my work for Company or unless expressly authorized by an officer of Company
in writing.

1.4     No Improper Use of Information of Prior Employers and Others. I
represent that my employment by Company does not and will not breach any
agreement with any former employer, including any noncompete agreement or any
agreement to keep in confidence or refrain from using information acquired by me
prior to my employment by Company. I further represent that I have not entered
into, and will not enter into, any agreement, either written or oral, in
conflict with my obligations under this Agreement. During my employment by
Company, I will not improperly make use of, or disclose, any information or
trade secrets of any former employer or other third party, nor will I bring onto
the premises of Company or use any unpublished documents or any property
belonging to any former employer or other third party, in violation of any
lawful agreements with that former employer or third party. I will use in the
performance of my duties only information that is generally known and used by
persons with training and experience comparable to my own, is common knowledge
in the industry or otherwise legally in the public domain, or is otherwise
provided or developed by Company.

2.Inventions.

2.1     Definitions. As used in this Agreement, the term “Invention” means any
ideas, concepts, information, materials, processes, data, programs, know-how,
improvements, discoveries, developments, designs, formulae, other copyrightable
works, and techniques and all Intellectual Property Rights in any of the items
listed above. The term “Intellectual Property Rights” means all trade secrets,
copyrights, trademarks, mask work rights, patents and other intellectual
property rights recognized by the laws of any jurisdiction or country. The term
“Moral Rights” means all paternity, integrity, disclosure, withdrawal, special
and any other similar rights recognized by the laws of any jurisdiction or
country.

2.2     Prior Inventions. I have disclosed on Exhibit A a complete list of all
Inventions that (a) I have, or I have

--------------------------------------------------------------------------------

caused to be, alone or jointly with others, conceived, developed, or reduced to
practice prior to the commencement of my employment by Company; (b) in which I
have an ownership interest or which I have a license to use; and (c) that I wish
to have excluded from the scope of this Agreement (collectively referred to as
“Prior Inventions”). If no Prior Inventions are listed in Exhibit A, I warrant
that there are no Prior Inventions. I agree that I will not incorporate, or
permit to be incorporated, Prior Inventions in any Company Inventions (defined
below) without Company’s prior written consent. If, in the course of my
employment with Company, I incorporate a Prior Invention into a Company process,
machine or other work, I hereby grant Company a non-exclusive, perpetual,
fully-paid and royalty-free, irrevocable and worldwide license, with rights to
sublicense through multiple levels of sublicensees, to reproduce, make
derivative works of, distribute, publicly perform, and publicly display in any
form or medium, whether now known or later developed, make, have made, use,
sell, import, offer for sale, and exercise any and all present or future rights
in, such Prior Invention.

2.3     Assignment of Company Inventions. Inventions assigned to the Company or
to a third party as directed by the Company pursuant to the subsection titled
Government or Third Party are referred to in this Agreement as “Company
Inventions.” Subject to the subsection titled Government or Third Party and
except for Inventions that I have set forth in Exhibit A, I hereby assign and
agree to assign in the future (when any such Inventions or Intellectual Property
Rights are first reduced to practice or first fixed in a tangible medium, as
applicable) to Company all my right, title, and interest in and to any and all
Inventions (and all Intellectual Property Rights with respect thereto) made,
conceived, reduced to practice, or learned by me, either alone or with others,
during the period of my employment by Company. Any assignment of Inventions (and
all Intellectual Property Rights with respect thereto) hereunder includes an
assignment of all Moral Rights. To the extent such Moral Rights cannot be
assigned to Company and to the extent the following is allowed by the laws in
any country where Moral Rights exist, I hereby unconditionally and irrevocably
waive the enforcement of such Moral Rights, and all claims and causes of action
of any kind against Company or related to Company’s customers, with respect to
such rights. I further acknowledge and agree that neither my
successors-in-interest nor legal heirs retain any Moral Rights in any Inventions
(and any Intellectual Property Rights with respect thereto).

2.4     Government or Third Party. I agree that, as directed by the Company, I
will assign to a third party, including without limitation the United States,
all my right, title, and interest in and to any particular Company Invention.

2.5     Enforcement of Intellectual Property Rights and Assistance. During and
after the period of my employment and at Company’s request and expense, I will
assist Company in every proper way, including consenting to and joining in any
action, to obtain and enforce United States and foreign Intellectual Property
Rights and Moral Rights relating to Company Inventions in all countries. If the
Company is unable to secure my signature on any document needed in connection
with such purposes, I hereby irrevocably designate and appoint Company and its
duly authorized officers and agents as my agent and attorney in fact, which
appointment is coupled with an interest, to act on my behalf to execute and file
any such documents and to do all other lawfully permitted acts to further such
purposes with the same legal force and effect as if executed by me.

3.Records. I agree to keep and maintain adequate and current records (in the
form of notes, sketches, drawings and in any other form that is required by the
Company) of all Inventions made by me during the period of my employment by the
Company, which records shall be available to, and remain the sole property of,
the Company at all times.

4.Additional Activities.

4.1     Noncompetition. During the term of my employment with the Company and
for a period of twelve (12) months immediately following the termination of my
employment with the Company for any reason, whether voluntary or involuntary,
or  with or without cause, I will not  within the United States or any other
geographic region in which the Company conducts its business, and in any
capacity, whether individually or as an employee, consultant, director, officer,
agent, advisor or otherwise for or on behalf of any entity (a “Competing
Organization”), engage in any business activities that are competitive with any
of the material business activities of the Company,  including without
limitation the research,  development, sale or marketing of any material
product, process or service, in existence or being conducted, provided or
developed by the Company, unless my duties at such Competing Organization do not
include duties relating to any product, process, service or business activity
that competes or is reasonably expected to compete with a material product,
process, service or business activity in existence or being conducted, provided
or developed by the Company, and provided that I have delivered to the Company a
written statement, confirmed by my prospective employer or consulting client, as
the case may be, describing my duties and stating that such duties are
consistent with my obligations under this Agreement.  I acknowledge and agree
that the covenants contained in this Section 4.1 are (i) reasonable and valid in
geographical and temporal scope and in all other respects and (ii) essential to
protect the value of the business and assets of the Company.  If any court of
competent jurisdiction shall at any time deem the duration or the geographic
scope of any of the provisions of this Section 4.1 unenforceable, the other
provisions of this Section 4.1 shall nevertheless stand, and the duration and/or
geographic scope set forth herein shall be deemed to be the longest period
and/or greatest size permissible by law under the circumstances, and the parties
hereto agree that such court shall reduce the time period and/or geographic
scope to permissible duration or size.

--------------------------------------------------------------------------------

4.2     Prior Relationships. Without limiting Section 4.1, I represent that I
have no other agreements, relationships or commitments to any other person or
entity that conflict with my obligations to the Company under this Agreement or
my ability to become employed and perform the services for which I am being
hired by the Company. I further agree that if I have signed a confidentiality
agreement or similar type of agreement with any former employer or other entity,
I will comply with the terms of any such agreement to the extent that its terms
are lawful under applicable law. I represent and warrant that after undertaking
a careful search (including searches of my computers, cell phones, electronic
devices and documents); I have returned all property and confidential
information belonging to all prior employers. Moreover, in the event that the
Company or any of its directors, officers, agents, employees, investors,
shareholders, administrators, affiliates, divisions, subsidiaries, predecessor
or successor corporations, or assigns is sued based on any obligation or
agreement to which I am a party or am bound, I agree to fully indemnify the
Company, its directors, officers, agents, employees, investors, shareholders,
administrators, affiliates, divisions, subsidiaries, predecessor and successor
corporations, and assigns for all verdicts, judgments, settlements, and other
losses incurred by the Company (the indemnitee) in the event that it is the
subject of any legal action resulting from any breach of my obligations under
this Agreement, as well as any reasonable attorneys’ fees and costs if the
plaintiff is the prevailing party in such an action.

4.3     Nonsolicitation. I agree that for the period of my employment by Company
and for a period of twelve (12) months immediately following the termination of
my employment with the Company for any reason, whether voluntary or involuntary,
with or without cause, I will not, either directly or indirectly, solicit or
attempt to solicit any employee, independent contractor, or consultant of
Company to terminate his, her or its relationship with Company in order to
become an employee, consultant, or independent contractor to or for any other
person or entity.

5.Return Of Company Property. Upon termination of my employment or upon
Company’s request at any other time, I will deliver to Company all of Company’s
property, equipment, and documents, together with all copies thereof, and any
other material containing or disclosing any Inventions, Third Party Information
or Confidential Information and certify in writing that I have fully complied
with the foregoing obligation. I agree that I will not copy, delete, or alter
any information contained upon my Company computer or Company equipment before I
return it to Company. In addition, if I have used any personal computer, server,
or e-mail system to receive, store, review, prepare or transmit any Company
information, including but not limited to, Confidential Information, I agree to
provide the Company with a computer-useable copy of all such Confidential
Information and then permanently delete and expunge such Confidential
Information from those systems; and I agree to provide the Company access to my
system as reasonably requested to verify that the necessary copying and/or
deletion is completed. I further agree that any property situated on Company’s
premises and owned by Company is subject to inspection by Company’s personnel at
any time with or without notice. Prior to the termination of my employment or
promptly after termination of my employment, I will cooperate with Company in
attending an exit interview and certify in writing that I have complied with the
requirements of this section.

6.Notification Of New Employer. If I leave the employ of Company, I consent to
the notification of my new employer of my rights and obligations under this
Agreement, by Company providing a copy of this Agreement or otherwise.

7.General Provisions.

7.1     Governing Law and Venue. This Agreement and any action related thereto
will be governed and interpreted by and under the laws of the Commonwealth of
Massachusetts, without giving effect to any conflicts of laws principles that
require the application of the law of a different state. I expressly consent to
personal jurisdiction and venue in the state and federal courts for the county
in which Company’s principal place of business is located for any lawsuit filed
there against me by Company arising from or related to this Agreement.

7.2     Severability. If any provision of this Agreement is, for any reason,
held to be invalid or unenforceable, the other provisions of this Agreement will
remain enforceable and the invalid or unenforceable provision will be deemed
modified so that it is valid and enforceable to the maximum extent permitted by
law.

7.3     Survival. This Agreement shall survive the termination of my employment
and the assignment of this Agreement by Company to any successor or other
assignee and shall be binding upon my heirs and legal representatives.

7.4     Employment. I agree and understand that nothing in this Agreement shall
give me any right to continued employment by Company, and it will not interfere
in any way with my right or Company’s right to terminate my employment at any
time, with or without cause and with or without advance notice.

7.5     Notices. Each party must deliver all notices or other communications
required or permitted under this Agreement in writing to the other party at the
address listed on the signature page, by courier, by certified or registered
mail (postage prepaid

--------------------------------------------------------------------------------

and return receipt requested), or by a nationally-recognized express mail
service. Notice will be effective upon receipt or refusal of delivery. If
delivered by certified or registered mail, notice will be considered to have
been given five (5) business days after it was mailed, as evidenced by the
postmark. If delivered by courier or express mail service, notice will be
considered to have been given on the delivery date reflected by the courier or
express mail service receipt. Each party may change its address for receipt of
notice by giving notice of the change to the other party.

7.6     Injunctive Relief. I acknowledge that, because my services are personal
and unique and because I will have access to the Confidential Information of
Company, any breach of this Agreement by me would cause irreparable injury to
Company for which monetary damages would not be an adequate remedy and,
therefore, will entitle Company to injunctive relief (including specific
performance). The rights and remedies provided to each party in this Agreement
are cumulative and in addition to any other rights and remedies available to
such party at law or in equity.

7.7     Waiver. Any waiver or failure to enforce any provision of this Agreement
on one occasion will not be deemed a waiver of that provision or any other
provision on any other occasion.

7.8     Export. I agree not to export, reexport, or transfer, directly or
indirectly, any U.S. technical data acquired from Company, or any products
utilizing such data, in violation of the United States export laws or
regulations.

7.9     Counterparts. This Agreement may be executed in one or more
counterparts, each of which shall be deemed an original and all of which shall
be taken together and deemed to be one instrument.

7.10     Entire Agreement. If no other agreement governs nondisclosure and
assignment of inventions during any period in which I was previously employed or
am in the future employed by Company as an independent contractor, the
obligations pursuant to sections of this Agreement titled Confidential
Information Protections and Inventions shall apply. This Agreement is the final,
complete and exclusive agreement of the parties with respect to the subject
matter hereof and supersedes and merges all prior communications between us with
respect to such matters. No modification of or amendment to this Agreement, or
any waiver of any rights under this Agreement, will be effective unless in
writing and signed by me and the CEO of Company. Any subsequent change or
changes in my duties, salary or compensation will not affect the validity or
scope of this Agreement.
 
This Agreement shall be effective as of __December 29_, 2014.

Employee:
I have read, understand, and Accept this agreement and have been given the
opportunity to Review it with independent legal counsel.

Exhibit C
ADEA DISCLOSURE

As you have been informed, Flex Pharma Inc. (along with its affiliates, the
“Company”) is terminating your employment as part of a job elimination or
reorganization at the Company. The Company is offering employees who have been
laid off as part of this job elimination or reorganization the opportunity to
receive certain severance benefits (“Severance Benefits”) as part of a group
termination program (“Program”) in exchange for, among other things, the
affected employee’s agreement to release any and all claims he or she may have
against the Company and related persons and entities. The terms of this offer as
it applies to you are described in the attached Separation Agreement and Release
(the “Separation Agreement”).
The federal Age Discrimination in Employment Act (the “ADEA”) requires that when
an employee who is 40 or more years of age is provided certain benefits and
asked to sign a release in connection with a group employment termination
program, the employee must be provided with certain information. Consistent with
this, the Company is providing that information to you.

1.
Eligibility: All Company employees who have been provided with the Separation
Agreement as part of the Program are eligible for Severance Benefits. The
Company determined which employees would be selected for layoff based on the
Company’s assessment of its future business needs and the extent to which
employees’ job duties, abilities and skill sets matched the Company’s future
business needs.

2.
Time Limits for Decisions Concerning the Severance Benefits: As set forth in the
attached Agreement, you have at least forty-five (45) days to review and sign
the Agreement and return it to Lauren Mastrocola at lmastrocola@flex-pharma.com.
You will have seven (7) days after you sign the Agreement to change your mind
and revoke it; if you do not do so, the Agreement will be effective on the
eighth day after you sign the Agreement.

3.
Listing of Persons Selected and Not Selected: Under the ADEA, some laid off
employees are entitled to certain information about other persons selected for
the Program and thus offered Severance Benefits and those who were not selected
and thus not offered Severance Benefits. The information to be provided covers
persons in the “decisional unit.” The decisional unit is the portion of the
Company’s organization from which the Company decided who would be selected for
the Program, and thus offered Severance Benefits, and who would not be selected
for the Program. In this case, the decisional unit is Flex Pharma Inc. The
following lists the ages and job titles of all employees in the decisional unit,
identifying those who were and were not selected for the Program.

This list is current as of the date it is provided to you.
