APPENDIX A

 

Payments Subject to Section 409A

 

		1.	Subject to this Appendix A, any severance payments that may be due under the Agreement shall begin only
upon the date of your “separation from service” (determined as set forth below) which occurs on or after the termination of
your employment. The following rules shall apply with respect to distribution of the severance payments, if any, to be provided to
you under the Agreement, as applicable:

 

		(a)	It is intended that each installment of the severance payments under the Agreement provided under shall
be treated as a separate “payment” for purposes of Section 409A. Neither the Company nor you shall have the right to
accelerate or defer the delivery of any such payments except to the extent specifically permitted or required by Section 409A.

 

		(b)	If, as of the date of your “separation from service” from the Company, you are not a “specified
employee” (within the meaning of Section 409A), then each installment of the severance payments shall be made on the dates
and terms set forth in the Agreement.

 

		(c)	If, as of the date of your “separation from service” from the Company, you are a “specified
employee” (within the meaning of Section 409A), then:

 

		(i)	Each installment of the severance payments due under the Agreement that, in accordance with the dates
and terms set forth herein, will in all circumstances, regardless of when your separation from service occurs, be paid within the short-term
deferral period (as defined under Section 409A) shall be treated as a short-term deferral within the meaning of Treasury Regulation
Section 1.409A-1(b)(4) to the maximum extent permissible under Section 409A and shall be paid on the dates and terms set
forth in the Agreement; and

 

		(ii)	Each installment of the severance payments due under the Agreement that is not described in this Appendix
A, Section 1(c)(i) and that would, absent this subsection, be paid within the six-month period following your “separation
from service” from the Company shall not be paid until the date that is six months and one day after such separation from service
(or, if earlier, your death), with any such installments that are required to be delayed being accumulated during the six-month period
and paid in a lump sum on the date that is six months and one day following your separation from service and any subsequent installments,
if any, being paid in accordance with the dates and terms set forth herein; provided, however, that the preceding provisions of this sentence
shall not apply to any installment of payments if and to the maximum extent that that such installment is deemed to be paid under a separation
pay plan that does not provide for a deferral of compensation by reason of the application of Treasury Regulation 1.409A-1(b)(9)(iii) (relating
to separation pay upon an involuntary separation from service). Any installments that qualify for the exception under Treasury Regulation
Section 1.409A-1(b)(9)(iii) must be paid no later than the last day of your second taxable year following the taxable year in
which the separation from service occurs.

  

    	 	Appendix A-1	 

     

    

 

2.            The
determination of whether and when your separation from service from the Company has occurred shall be made and in a manner consistent
with, and based on the presumptions set forth in, Treasury Regulation Section 1.409A-1(h). Solely for purposes of this Appendix A,
Section 2, “Company” shall include all persons with whom the Company would be considered a single employer under Section 414(b) and
414(c) of the Code.

 

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

EXHIBIT B

 

Employee Non-Solicitation, Confidentiality and
Assignment Agreement

 

In consideration and as a
condition of NAME (“I”, “Me”, or “You”) employment or continued employment by ProMIS Neurosciences.
(“ProMIS”), the parties hereby agree as follows:

 

1.            Proprietary
Information. I agree that all information, whether or not in writing, whether or not disclosed before or after I was first
employed by ProMIS, concerning the business, technology, business relationships or financial affairs of ProMIS or its subsidiaries, affiliates,
and associated entities (collectively, the “Company”) that the Company has not released to the general public (collectively,
 “Proprietary Information”), and all tangible embodiments thereof, are and will be the exclusive property of the Company.
By way of illustration, Proprietary Information may include information or material that has not been made generally available to the
public, such as: (a) corporate information, including plans, strategies, methods, policies, resolutions, notes, email correspondence,
negotiations or litigation; (b) marketing information, including strategies, methods, customer identities or other information
about customers, prospect identities or other information about prospects, or market analyses or projections; (c) financial information,
including cost and performance data, debt arrangements, equity structure, investors and holdings, purchasing and sales data and price
lists; and (d) operational and technological information, including plans, specifications, manuals, forms, templates, software,
designs, methods, procedures, formulas, discoveries, inventions, improvements, biological or chemical materials, concepts and ideas;
and (e) personnel information, including personnel lists, reporting or organizational structure, resumes, personnel data,
compensation structure, performance evaluations and termination arrangements or documents. Proprietary Information includes, without
limitation, (1) information received in confidence by the Company from its customers or suppliers or other third parties, and (2) all
biological or chemical materials and other tangible embodiments of the Proprietary Information.

 

2.            Recognition
of Company’s Rights. I will not, at any time, without the Company’s prior written permission, either during or
after my employment, disclose or transfer any Proprietary Information to anyone outside of the Company, or use or permit to be used any
Proprietary Information for any purpose other than the performance of my duties as an employee of the Company. I will cooperate with the
Company and use my best efforts to prevent the unauthorized disclosure of all Proprietary Information. I will deliver to the Company all
copies and other tangible embodiments of Proprietary Information in my possession or control upon the earlier of a request by the Company
or termination of my employment. The term “Proprietary Information” hereunder will not include information that I can establish
by competent written evidence (i) is or becomes generally known within the Company’s industry through no fault of mine; (ii) was
known to me at the time it was disclosed; (iii) is lawfully and in good faith made available to me by a third-party who did not derive
it from the Company and who imposes no obligation of confidence on me; or (iv) is required to be disclosed by order of a governmental
authority or a court of competent jurisdiction, provided that such disclosure is subject to all applicable governmental or judicial protection
available for like material, and provided I first give reasonable advance written notice of such requirement to the Company, and permit
the Company to intervene in any relevant proceedings to protect its interests in the Proprietary Information, and provide full cooperation
and assistance to the Company in seeking to obtain such protection.

 

    	 	Exhibit B-1	 

     

    

 

3.            Rights
of Others. I understand that the Company is now and may hereafter be subject to non-disclosure
or confidentiality agreements with third persons which require the Company to protect or refrain from use of proprietary information.
I agree to be bound by the terms of such agreements in the event I have access to such proprietary information.

 

4.            Commitment
to Company; Avoidance of Conflict of Interest. While an employee of the Company, I
will devote my full-time efforts to the Company’s business and I will not engage in any other business activity that conflicts
or reasonably could potentially conflict with my duties to the Company. I will advise the president of the Company or their nominee at
such time as any activity of either the Company or another business presents me with a conflict of interest or the appearance of a conflict
of interest as an employee of the Company. I will take whatever action is requested of me by the Company to resolve any conflict or appearance
of conflict which it finds to exist.

 

5.            Developments.
I hereby assign and transfer and, to the extent any such assignment cannot be made at present, hereby agree to assign and transfer, to
ProMIS and its successors, designees and assigns, all my right, title and interest in and to all Developments (as defined below) that:
(a) are created, developed, made, conceived or reduced to practice by me (alone or jointly with others) or under my direction (collectively,
 “conceived”) during the period of my employment and six (6) months thereafter and that relate to the business of the
Company or to products, methods or services being researched, developed, manufactured or sold by the Company; or (b) result from
tasks assigned to me by the Company; or (c) result from the use of premises, Proprietary Information or personal property (whether
tangible or intangible) owned, licensed or leased by the Company (collectively, “Company-Related Developments”), and all
patent rights, trademarks, copyrights and other intellectual property rights in all countries and territories worldwide claiming, covering
or otherwise arising from or pertaining to Company-Related Developments (collectively, “Intellectual Property Rights”). I
further agree that “Company-Related Developments” include, without limitation, all Developments that (i) were conceived
by me before my employment, (ii) relate to the business of the Company or to products, methods or services being researched, developed,
manufactured or sold by the Company, and (iii) were not subject to an obligation to assign to another entity when conceived. I will
make full and prompt disclosure to the Company of all Company-Related Developments, as well as all other Developments conceived by me
during the period of my employment and six (6)  months thereafter. I acknowledge that all work performed by me as an employee of
the Company is on a “work for hire” basis. I hereby waive all claims to any moral rights or other special rights which I
may have or accrue in any Company-Related Developments. “Developments” mean inventions, discoveries, designs, developments,
methods, modifications, improvements, processes, biological or chemical materials, algorithms, databases, computer programs, formulae,
techniques, trade secrets, graphics or images, audio or visual works, and other works of authorship.

 

    	 	Exhibit B-2	 

     

    

 

To preclude any possible uncertainty, I
have set forth on Exhibit A attached hereto a complete list of Developments conceived by me before my employment that are
not Company-Related Developments (“Prior Inventions”). I have also listed on Exhibit A all patent rights of which
I am an inventor, other than those contained within Intellectual Property Rights (“Other Patent Rights”). If no such disclosure
is attached, I represent that there are no Prior Inventions or Other Patent Rights. If, in the course of my employment with the Company, I
incorporate a Prior Invention into a Company product, process or research or development program or other work done for the Company, I
hereby grant to the Company a nonexclusive, royalty-free, fully paid-up, irrevocable, perpetual, worldwide license (with the full right
to sublicense through multiple tiers) to make, have made, modify, use, offer for sale, import and sell such Prior Invention. Notwithstanding
the foregoing, I will not incorporate, or permit to be incorporated, Prior Inventions in any Company-Related Development without
the Company’s prior written consent.

 

I understand that to the extent
this Agreement is required to be construed in accordance with the laws of any state which precludes a requirement in an employee agreement
to assign certain classes of inventions made by an employee, this Section will be interpreted not to apply to any invention which
a court rules and/or the Company agrees falls within such classes.

 

6.            Documents
and Other Materials. I will keep and maintain adequate and current records of all Proprietary Information and Company-Related
Developments conceived by me, which records will be available to and remain the sole property of the Company at all times. All files,
letters, notes, memoranda, reports, records, data, sketches, drawings, notebooks, layouts, charts, quotations and proposals, specification
sheets, program listings, blueprints, models, prototypes, materials or other written, photographic or other tangible material containing
or embodying Proprietary Information, whether created by me or others, which come into my custody or possession, are the exclusive property
of the Company to be used by me only in the performance of my duties for the Company. In the event of the termination of my employment
for any reason, I will deliver to the Company all of the foregoing, and all other materials of any nature pertaining to the Proprietary
Information of the Company and to my work, and will not take or keep in my possession any of the foregoing or any copies. Any property
situated on the Company’s premises and owned by the Company, including laboratory space, computers, disks and other storage media,
filing cabinets or other work areas, is subject to inspection by the Company at any time with or without notice.

 

7.            Enforcement
of Intellectual Property Rights. I will cooperate fully with the Company, both during and after my employment with the Company,
with respect to the procurement, maintenance and enforcement of Intellectual Property Rights, as well as all other patent rights, trademarks,
copyrights and other intellectual property rights in all countries and territories worldwide owned by or licensed to the Company. I will
sign, both during and after the term of this Agreement, all papers, including copyright applications, patent applications, declarations,
oaths, assignments of priority rights, and powers of attorney, which the Company may deem necessary or desirable in order to protect its
rights and interests in any Company-Related Development or Intellectual Property Rights. If the Company is unable, after reasonable effort,
to secure my signature on any such papers, I hereby irrevocably designate and appoint each officer of the Company as my agent and
attorney-in-fact to execute any such papers on my behalf, and to take any and all actions as the Company may deem necessary or desirable
in order to protect its rights and interests in the same.

 

    	 	Exhibit B-3	 

     

    

 

8.            Non-Solicitation.
In order to protect the Company’s Proprietary Information and good will, during my employment and for a period of twelve (12) months
following a for Cause (as defined below) termination of my employment (the “Restricted Period”), I will not, directly
or indirectly, in any manner, other than for the benefit of the Company, (a) call upon, solicit, divert or take away any of the
customers, business or prospective customers of the Company or any of its suppliers, and/or (b) solicit, entice or attempt to persuade
any other employee or consultant of the Company to leave the services of the Company for any reason. I acknowledge and agree that if
I violate any of the provisions of this Section, the running of the Restricted Period will be extended by the time during which I engage
in such violation(s).

 

9.            Government
Contracts. I acknowledge that the Company may have from time to time agreements with
other persons or with the United States Government or its agencies which impose obligations or restrictions on the Company regarding
inventions made during the course of work under such agreements or regarding the confidential nature of such work. I agree to comply
with any such obligations or restrictions upon the direction of the Company. In addition to the rights assigned under Section 5, I
also assign to the Company (or any of its nominees) all rights which I have or acquired in any Developments, full title to which is required
to be in the United States under any contract between the Company and the United States or any of its agencies.

 

10.         Prior
Agreements. I hereby represent that, except as I have fully disclosed previously in writing
to the Company, I am not bound by the terms of any agreement with any current or previous employer or other party that interferes
with my performance under this Agreement or obligates me to refrain from using or disclosing any trade secret or confidential or proprietary
information in the course of my employment with the Company or to refrain from competing, directly or indirectly, with the business of
such previous employer or any other party, or to assign any patent rights, trademarks, copyrights or other intellectual property rights.
I further represent that my performance of all the terms of this Agreement as an employee of the Company does not and will not breach
any agreement to keep in confidence proprietary information, knowledge or data acquired by me in confidence or in trust prior to my employment
with the Company. I will not disclose to the Company or induce the Company to use any confidential or proprietary information or material
belonging to any previous employer or others.

 

11.          Remedies
Upon Breach. I understand that the restrictions contained in this Agreement are necessary
for the protection of the business and goodwill of the Company and I consider them to be reasonable for such purpose. Any breach of this
Agreement is likely to cause the Company substantial and irrevocable damage and therefore, in the event of such breach, the Company, in
addition to such other remedies which may be available, will be entitled to specific performance and other injunctive relief.

 

    	 	Exhibit B-4	 

     

    

 

12.         Use
of Voice, Image and Likeness. I give the Company permission to use my voice, image
or likeness, with or without using my name, for the purposes of advertising and promoting the Company, or for other purposes deemed appropriate
by the Company in its reasonable discretion, except to the extent expressly prohibited by law.

 

13.         Publications
and Public Statements. I will obtain the Company’s written approval before publishing
or submitting for publication any material that relates to my work at the Company and/or incorporates any Proprietary Information. To
ensure that the Company delivers a consistent message about its products, services and operations to the public, and further in recognition
that even positive statements may have a detrimental effect on the Company in certain contexts, any statement about the Company which
I create, publish or post during my period of employment and for six (6) months thereafter, on any media accessible by the public,
including but not limited to electronic bulletin boards and Internet-based chat rooms, must first be reviewed and approved by an officer
of the Company before it is released in the public domain.

 

14.         No
Employment Obligation. I understand that this Agreement does not create an obligation
on the Company or any other person to continue my employment. I acknowledge that, unless otherwise agreed in a formal written employment
agreement signed on behalf of the Company by an authorized officer, my employment with the Company is at will and therefore may be terminated
by the Company or me at any time and for any reason. Without limiting the foregoing in any manner, You may be immediately terminated,
without notice, for Cause or without Cause. “Cause” as used herein shall mean: (i) a breach of Your obligations under
this Agreement or any other agreement you have with the Company; (ii) the failure or refusal to follow the instructions of Your
supervisor or the Board of Directors of the Company, as the case may be; (iii) the commission by You of any act of dishonesty, moral
turpitude, fraud, or breach of trust; (iv) conviction of, or pleading guilty or no contest to, any felony or any lesser crime; (v) the
failure to adhere to policies and procedures adopted by the Company from time to time.

 

15.         Survival
and Assignment by the Company. I understand that my obligations under this Agreement
will continue in accordance with its express terms regardless of any changes in my title, position, duties, salary, compensation or benefits
(if any) or other terms and conditions of employment. I further understand that my obligations under this Agreement will continue following
the termination of my employment regardless of the manner of such termination and will be binding upon my heirs, executors and administrators.
The Company will have the right to assign this Agreement to its affiliates, successors and assigns. I expressly consent to be bound by
the provisions of this Agreement for the benefit of the Company or any parent, subsidiary or affiliate to whose employ I may be transferred
without the necessity that this Agreement be resigned at the time of such transfer.

 

16.         Disclosure
to Future Employers and Others. During the period in which the terms of the Non-Solicitation
agreement described in Section 8 and the Developments agreement in Section 5 remain in force, I will provide a copy of
this Agreement to any prospective employer, partner or co-venturer prior to entering into an employment, partnership or other business
relationship with such person or entity.

17.         Exit
Interview. If and when I depart from the Company, I may be required to attend an
exit interview and sign an “Employee Exit Acknowledgement” to reaffirm my acceptance and acknowledgement of the obligations
set forth in this Agreement. During the Restricted Period following termination of my employment, I will notify the Company of any
change in my address and of each subsequent engagement, employment or business activity, including the name and address of my employer,
party to which I render services or other post-Company employment or engagement plans and the nature of my activities.

 

18.         Severability.
In case any provisions (or portions thereof) contained in this Agreement will, for any reason, be held invalid, illegal or unenforceable
in any respect, such invalidity, illegality or unenforceability will not affect the other provisions of this Agreement, and this Agreement
will be construed as if such invalid, illegal or unenforceable provision had never been contained herein. If, moreover, any one or more
of the provisions contained in this Agreement will for any reason be held to be excessively broad as to duration, geographical scope,
activity or subject, it will be construed by limiting and reducing it, so as to be enforceable to the extent compatible with the applicable
law as it will then appear.

 

19.         Entire
Agreement. This Agreement constitutes the entire and only agreement between the Company
and me respecting the subject matter hereof, and supersedes all prior agreements and understandings, oral or written, between us concerning
such subject matter. No modification, amendment, waiver or termination of this Agreement or of any provision hereof will be binding unless
made in writing and signed by an authorized officer of the Company. Failure of the Company to insist upon strict compliance with any
of the terms, covenants or conditions hereof will not be deemed a waiver of such terms, covenants or conditions. In the event of any
inconsistency between this Agreement and any other contract between the Company and me, the provisions of this Agreement will prevail.

 

20.         Interpretation.
This Agreement will be deemed to be made and entered into in the Commonwealth of Massachusetts, and will in all respects be interpreted,
enforced and governed under the laws of the Commonwealth of Massachusetts. I hereby agree to consent to personal jurisdiction of the
Suffolk County Business Litigation Session for purposes of enforcing this Agreement, and waive any objection that I might have to personal
jurisdiction or venue in this court. As used in this Agreement, “including” means “including but not limited to”.

of management); or (iv) a material breach by the Company of its obligations under this offer letter. No resignation will be treated
as a resignation for Good Reason unless (x) you have given written notice to the Company of your intention to terminate your employment
for Good Reason, describing the grounds for such action, no later than 90 days after the first occurrence of such circumstances, (y) you
have provided the Company with at least 30 days in which to cure the circumstances, and (z) if the Company is not successful in curing
the circumstance s, you end your employment within 60 days following the cure period in (y).

 

You will be required to execute
a Non-Solicitation, Confidentiality and Assignment Agreement in the form attached as Exhibit B, as a condition of employment.

 

You represent that you are
not bound by any employment contract, restrictive covenant or other restriction preventing (or that purports to prevent) you from entering

You agree to provide to the
Company, within three days of your hire date, documentation of your eligibility to work in the United States, as required by the Immigration
Reform and Control Act of 1986. You may need to obtain a work visa in order to be eligible to work in the United States. If that is the
case, your employment with the Company will be conditioned upon your obtaining a work visa in a timely manner as determined by the Company.

 

This letter shall not be construed
as an agreement, either expressed or implied, to employ you for any stated term, and shall in no way alter the Company’s policy
of employment at will, under which both you and the Company remain free to terminate the employment relationship, with or without cause,
at any time, with or without notice. Although your job duties, title, compensation and benefits, as well as the Company’s personnel
policies and procedures, may change from time to time, the “at-will” nature of your employment may only be changed by a written
agreement signed by you and the Company’s Chief Executive Officer, which expressly states the intention to modify the at-will
nature of your employment. Similarly, except as expressly provided herein, nothing in this letter shall be construed as an agreement,
either express or implied, to pay you any compensation or grant you any benefit beyond the end of your employment with the Company.

 

In return for the compensation
payments set forth in this letter, you agree to devote your full business time, best efforts, skill, knowledge, attention, and energies
to the advancement of the Company’s business and interests and to the performance of your duties and responsibilities as an employee
of the Company and not to engage in any other business activities without prior approval from the Company.

 

As an employee of the Company,
you will be required to comply with all Company policies and procedures. Violations of the Company’s policies may lead to immediate
termination of your employment. Further, the Company’s premises, including all workspaces, furniture, documents, and other tangible
materials, and all information technology resources of the Company (including computers, data and other electronic files, and all internet
and email) are subject to oversight and inspection by the Company at any time. Company employees should have no expectation of privacy
with regard to any Company premises, materials, resources, or information.

 

This offer letter is your
formal offer of employment and supersedes any and all prior or contemporaneous agreements, discussions and understandings, whether written
or oral, relating to the subject matter of this letter or your employment with the Company. The resolution of any disputes under this
letter will be governed by the laws of the Commonwealth of Massachusetts.

APPENDIX A

 

Payments Subject to Section 409A

 

		1.	Subject to this Appendix A, any severance payments that may be due under the Agreement shall begin only
upon the date of your “separation from service” (determined as set forth below) which occurs on or after the termination of
your employment. The following rules shall apply with respect to distribution of the severance payments, if any, to be provided to
you under the Agreement, as applicable:

 

		(a)	It is intended that each installment of the severance payments under the Agreement provided under shall
be treated as a separate “payment” for purposes of Section 409A. Neither the Company nor you shall have the right to
accelerate or defer the delivery of any such payments except to the extent specifically permitted or required by Section 409A.

 

		(b)	If, as of the date of your “separation from service” from the Company, you are not a “specified
employee” (within the meaning of Section 409A), then each installment of the severance payments shall be made on the dates
and terms set forth in the Agreement.

 

		(c)	If, as of the date of your “separation from service” from the Company, you are a “specified
employee” (within the meaning of Section 409A), then:

 

		(i)	Each installment of the severance payments due under the Agreement that, in accordance with the dates
and terms set forth herein, will in all circumstances, regardless of when your separation from service occurs, be paid within the short-term
deferral period (as defined under Section 409A) shall be treated as a short-term deferral within the meaning of Treasury Regulation
Section 1.409A-1(b)(4) to the maximum extent permissible under Section 409A and shall be paid on the dates and terms set
forth in the Agreement; and

 

		(ii)	Each installment of the severance payments due under the Agreement that is not described in this Appendix
A, Section 1(c)(i) and that would, absent this subsection, be paid within the six-month period following your “separation
from service” from the Company shall not be paid until the date that is six months and one day after such separation from service
(or, if earlier, your death), with any such installments that are required to be delayed being accumulated during the six-month period
and paid in a lump sum on the date that is six months and one day following your separation from service and any subsequent installments,
if any, being paid in accordance with the dates and terms set forth herein; provided, however, that the preceding provisions of this sentence
shall not apply to any installment of payments if and to the maximum extent that that such installment is deemed to be paid under a separation
pay plan that does not provide for a deferral of compensation by reason of the application of Treasury Regulation 1.409A-1(b)(9)(iii) (relating
to separation pay upon an involuntary separation from service). Any installments that qualify for the exception under Treasury Regulation
Section 1.409A-1(b)(9)(iii) must be paid no later than the last day of your second taxable year following the taxable year in
which the separation from service occurs.

 

    Appendix A - 1

     

    

 

		2.	The determination of whether and when your separation from service from the Company has occurred shall
be made and in a manner consistent with, and based on the presumptions set forth in, Treasury Regulation Section 1.409A-1(h). Solely
for purposes of this Appendix A, Section 2, “Company” shall include all persons with whom the Company would be considered
a single employer under Section 414(b) and 414(c) of the Code.

 

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

NON-SOLICITATION, CONFIDENTIALITY and ASSIGNMENT
AGREEMENT

 

Employee Non-Solicitation, Confidentiality and
Assignment Agreement

 

In consideration and as a
condition of NAME (“I”, “Me”, or “You”) employment or continued employment by ProMIS Neurosciences.
(“ProMIS”), the parties hereby agree as follows:

 

1.            Proprietary
Information. I agree that all information, whether or not in writing, whether or not disclosed before or after I was first
employed by ProMIS, concerning the business, technology, business relationships or financial affairs of ProMIS or its subsidiaries, affiliates,
and associated entities (collectively, the “Company”) that the Company has not released to the general public (collectively,
 “Proprietary Information”), and all tangible embodiments thereof, are and will be the exclusive property of the Company. By
way of illustration, Proprietary Information may include information or material that has not been made generally available to the public,
such as: (a) corporate information, including plans, strategies, methods, policies, resolutions, notes, email correspondence,
negotiations or litigation; (b) marketing information, including strategies, methods, customer identities or other information
about customers, prospect identities or other information about prospects, or market analyses or projections; (c) financial information,
including cost and performance data, debt arrangements, equity structure, investors and holdings, purchasing and sales data and price
lists; and (d) operational and technological information, including plans, specifications, manuals, forms, templates, software,
designs, methods, procedures, formulas, discoveries, inventions, improvements, biological or chemical materials, concepts and ideas; and
(e) personnel information, including personnel lists, reporting or organizational structure, resumes, personnel data, compensation
structure, performance evaluations and termination arrangements or documents. Proprietary Information includes, without limitation, (1) information
received in confidence by the Company from its customers or suppliers or other third parties, and (2) all biological or chemical
materials and other tangible embodiments of the Proprietary Information.

 

2.            Recognition
of Company’s Rights. I will not, at any time, without the Company’s prior written permission, either during or
after my employment, disclose or transfer any Proprietary Information to anyone outside of the Company, or use or permit to be used any
Proprietary Information for any purpose other than the performance of my duties as an employee of the Company. I will cooperate with the
Company and use my best efforts to prevent the unauthorized disclosure of all Proprietary Information. I will deliver to the Company all
copies and other tangible embodiments of Proprietary Information in my possession or control upon the earlier of a request by the Company
or termination of my employment. The term “Proprietary Information” hereunder will not include information that I can establish
by competent written evidence (i) is or becomes generally known within the Company’s industry through no fault of mine; (ii) was
known to me at the time it was disclosed; (iii) is lawfully and in good faith made available to me by a third-party who did not derive
it from the Company and who imposes no obligation of confidence on me; or (iv) is required to be disclosed by order of a governmental
authority or a court of competent jurisdiction, provided that such disclosure is subject to all applicable governmental or judicial protection
available for like material, and provided I first give reasonable advance written notice of such requirement to the Company, and permit
the Company to intervene in any relevant proceedings to protect its interests in the Proprietary Information, and provide full cooperation
and assistance to the Company in seeking to obtain such protection.

 

     Exhibit B - 1

    

    

 

3.            Rights
of Others. I understand that the Company is now and may hereafter be subject to non-disclosure
or confidentiality agreements with third persons which require the Company to protect or refrain from use of proprietary information.
I agree to be bound by the terms of such agreements in the event I have access to such proprietary information.

 

4.            Commitment
to Company; Avoidance of Conflict of Interest. While an employee of the Company, I
will devote my full-time efforts to the Company’s business and I will not engage in any other business activity that conflicts or
reasonably could potentially conflict with my duties to the Company. I will advise the president of the Company or their nominee at such
time as any activity of either the Company or another business presents me with a conflict of interest or the appearance of a conflict
of interest as an employee of the Company. I will take whatever action is requested of me by the Company to resolve any conflict or appearance
of conflict which it finds to exist.

 

5.            Developments.
I hereby assign and transfer and, to the extent any such assignment cannot be made at present, hereby agree to assign and transfer, to
ProMIS and its successors, designees and assigns, all my right, title and interest in and to all Developments (as defined below) that:
(a) are created, developed, made, conceived or reduced to practice by me (alone or jointly with others) or under my direction (collectively,
 “conceived”) during the period of my employment and six (6) months thereafter and that relate to the business of the
Company or to products, methods or services being researched, developed, manufactured or sold by the Company; or (b) result from
tasks assigned to me by the Company; or (c) result from the use of premises, Proprietary Information or personal property (whether
tangible or intangible) owned, licensed or leased by the Company (collectively, “Company-Related Developments”), and all patent
rights, trademarks, copyrights and other intellectual property rights in all countries and territories worldwide claiming, covering or
otherwise arising from or pertaining to Company-Related Developments (collectively, “Intellectual Property Rights”). I further
agree that “Company-Related Developments” include, without limitation, all Developments that (i) were conceived by me
before my employment, (ii) relate to the business of the Company or to products, methods or services being researched, developed,
manufactured or sold by the Company, and (iii) were not subject to an obligation to assign to another entity when conceived. I will
make full and prompt disclosure to the Company of all Company-Related Developments, as well as all other Developments conceived by me
during the period of my employment and six (6)  months thereafter. I acknowledge that all work performed by me as an employee of
the Company is on a “work for hire” basis. I hereby waive all claims to any moral rights or other special rights which I may
have or accrue in any Company-Related Developments. “Developments” mean inventions, discoveries, designs, developments, methods,
modifications, improvements, processes, biological or chemical materials, algorithms, databases, computer programs, formulae, techniques,
trade secrets, graphics or images, audio or visual works, and other works of authorship.

 

     Exhibit B - 2

    

    

 

To preclude any possible uncertainty, I
have set forth on Exhibit A attached hereto a complete list of Developments conceived by me before my employment that are
not Company-Related Developments (“Prior Inventions”). I have also listed on Exhibit A all patent rights of which
I am an inventor, other than those contained within Intellectual Property Rights (“Other Patent Rights”). If no such disclosure
is attached, I represent that there are no Prior Inventions or Other Patent Rights. If, in the course of my employment with the Company, I
incorporate a Prior Invention into a Company product, process or research or development program or other work done for the Company, I
hereby grant to the Company a nonexclusive, royalty-free, fully paid-up, irrevocable, perpetual, worldwide license (with the full right
to sublicense through multiple tiers) to make, have made, modify, use, offer for sale, import and sell such Prior Invention. Notwithstanding
the foregoing, I will not incorporate, or permit to be incorporated, Prior Inventions in any Company-Related Development without
the Company’s prior written consent.

 

I
understand that to the extent this Agreement is required to be construed in accordance with the laws of any state which precludes a requirement
in an employee agreement to assign certain classes of inventions made by an employee, this Section will be interpreted not to apply
to any invention which a court rules and/or the Company agrees falls within such classes.

 

6.            Documents
and Other Materials. I will keep and maintain adequate and current records of all Proprietary Information and Company-Related
Developments conceived by me, which records will be available to and remain the sole property of the Company at all times. All files,
letters, notes, memoranda, reports, records, data, sketches, drawings, notebooks, layouts, charts, quotations and proposals, specification
sheets, program listings, blueprints, models, prototypes, materials or other written, photographic or other tangible material containing
or embodying Proprietary Information, whether created by me or others, which come into my custody or possession, are the exclusive property
of the Company to be used by me only in the performance of my duties for the Company. In the event of the termination of my employment
for any reason, I will deliver to the Company all of the foregoing, and all other materials of any nature pertaining to the Proprietary
Information of the Company and to my work, and will not take or keep in my possession any of the foregoing or any copies. Any property
situated on the Company’s premises and owned by the Company, including laboratory space, computers, disks and other storage media,
filing cabinets or other work areas, is subject to inspection by the Company at any time with or without notice.

 

7.            Enforcement
of Intellectual Property Rights. I will cooperate fully with the Company, both during and after my employment with the Company,
with respect to the procurement, maintenance and enforcement of Intellectual Property Rights, as well as all other patent rights, trademarks,
copyrights and other intellectual property rights in all countries and territories worldwide owned by or licensed to the Company. I will
sign, both during and after the term of this Agreement, all papers, including copyright applications, patent applications, declarations,
oaths, assignments of priority rights, and powers of attorney, which the Company may deem necessary or desirable in order to protect its
rights and interests in any Company-Related Development or Intellectual Property Rights. If the Company is unable, after reasonable effort,
to secure my signature on any such papers, I hereby irrevocably designate and appoint each officer of the Company as my agent and
attorney-in-fact to execute any such papers on my behalf, and to take any and all actions as the Company may deem necessary or desirable
in order to protect its rights and interests in the same.

 

     Exhibit B - 3

    

    

 

8.            Non-Solicitation.
In order to protect the Company’s Proprietary Information and good will, during my employment and for a period of twelve (12) months
following a for Cause (as defined below) termination of my employment (the “Restricted Period”), I will not, directly
or indirectly, in any manner, other than for the benefit of the Company, (a) call upon, solicit, divert or take away any of the customers,
business or prospective customers of the Company or any of its suppliers, and/or (b) solicit, entice or attempt to persuade any other
employee or consultant of the Company to leave the services of the Company for any reason. I acknowledge and agree that if I violate any
of the provisions of this Section, the running of the Restricted Period will be extended by the time during which I engage in such violation(s).

 

9.            Government
Contracts. I acknowledge that the Company may have from time to time agreements with
other persons or with the United States Government or its agencies which impose obligations or restrictions on the Company regarding
inventions made during the course of work under such agreements or regarding the confidential nature of such work. I agree to comply
with any such obligations or restrictions upon the direction of the Company. In addition to the rights assigned under Section 5, I
also assign to the Company (or any of its nominees) all rights which I have or acquired in any Developments, full title to which is required
to be in the United States under any contract between the Company and the United States or any of its agencies.

 

10.          Prior
Agreements. I hereby represent that, except as I have fully disclosed previously in writing
to the Company, I am not bound by the terms of any agreement with any current or previous employer or other party that interferes
with my performance under this Agreement or obligates me to refrain from using or disclosing any trade secret or confidential or proprietary
information in the course of my employment with the Company or to refrain from competing, directly or indirectly, with the business of
such previous employer or any other party, or to assign any patent rights, trademarks, copyrights or other intellectual property rights.
I further represent that my performance of all the terms of this Agreement as an employee of the Company does not and will not breach
any agreement to keep in confidence proprietary information, knowledge or data acquired by me in confidence or in trust prior to my employment
with the Company. I will not disclose to the Company or induce the Company to use any confidential or proprietary information or material
belonging to any previous employer or others.

 

11.          Remedies
Upon Breach. I understand that the restrictions contained in this Agreement are necessary
for the protection of the business and goodwill of the Company and I consider them to be reasonable for such purpose. Any breach of this
Agreement is likely to cause the Company substantial and irrevocable damage and therefore, in the event of such breach, the Company, in
addition to such other remedies which may be available, will be entitled to specific performance and other injunctive relief.

 

     Exhibit B - 4

    

    

 

12.          Use
of Voice, Image and Likeness. I give the Company permission to use my voice, image
or likeness, with or without using my name, for the purposes of advertising and promoting the Company, or for other purposes deemed appropriate
by the Company in its reasonable discretion, except to the extent expressly prohibited by law.

 

13.          Publications
and Public Statements. I will obtain the Company’s written approval before publishing
or submitting for publication any material that relates to my work at the Company and/or incorporates any Proprietary Information. To
ensure that the Company delivers a consistent message about its products, services and operations to the public, and further in recognition
that even positive statements may have a detrimental effect on the Company in certain contexts, any statement about the Company which
I create, publish or post during my period of employment and for six (6) months thereafter, on any media accessible by the public,
including but not limited to electronic bulletin boards and Internet-based chat rooms, must first be reviewed and approved by an officer
of the Company before it is released in the public domain.

 

14.          No
Employment Obligation. I understand that this Agreement does not create an obligation
on the Company or any other person to continue my employment. I acknowledge that, unless otherwise agreed in a formal written employment
agreement signed on behalf of the Company by an authorized officer, my employment with the Company is at will and therefore may be terminated
by the Company or me at any time and for any reason. Without limiting the foregoing in any manner, You may be immediately terminated,
without notice, for Cause or without Cause. “Cause” as used herein shall mean: (i) a breach of Your obligations under
this Agreement or any other agreement you have with the Company; (ii) the failure or refusal to follow the instructions of Your supervisor
or the Board of Directors of the Company, as the case may be; (iii) the commission by You of any act of dishonesty, moral turpitude,
fraud, or breach of trust; (iv) conviction of, or pleading guilty or no contest to, any felony or any lesser crime; (v) the
failure to adhere to policies and procedures adopted by the Company from time to time.

 

15.         Survival
and Assignment by the Company. I understand that my obligations under this Agreement will
continue in accordance with its express terms regardless of any changes in my title, position, duties, salary, compensation or benefits
(if any) or other terms and conditions of employment. I further understand that my obligations under this Agreement will continue following
the termination of my employment regardless of the manner of such termination and will be binding upon my heirs, executors and administrators.
The Company will have the right to assign this Agreement to its affiliates, successors and assigns. I expressly consent to be bound by
the provisions of this Agreement for the benefit of the Company or any parent, subsidiary or affiliate to whose employ I may be transferred
without the necessity that this Agreement be resigned at the time of such transfer.

 

16.          Disclosure
to Future Employers and Others. During the period in which the terms of the Non-Solicitation
agreement described in Section 8 and the Developments agreement in Section 5 remain in force, I will provide a copy of
this Agreement to any prospective employer, partner or co-venturer prior to entering into an employment, partnership or other business
relationship with such person or entity.

 

     Exhibit B - 5

    

    

 

17.          Exit
Interview. If and when I depart from the Company, I may be required to attend an
exit interview and sign an “Employee Exit Acknowledgement” to reaffirm my acceptance and acknowledgement of the obligations
set forth in this Agreement. During the Restricted Period following termination of my employment, I will notify the Company of any
change in my address and of each subsequent engagement, employment or business activity, including the name and address of my employer,
party to which I render services or other post-Company employment or engagement plans and the nature of my activities.

 

18.         Severability.
In case any provisions (or portions thereof) contained in this Agreement will, for any reason, be held invalid, illegal or unenforceable
in any respect, such invalidity, illegality or unenforceability will not affect the other provisions of this Agreement, and this Agreement
will be construed as if such invalid, illegal or unenforceable provision had never been contained herein. If, moreover, any one or more
of the provisions contained in this Agreement will for any reason be held to be excessively broad as to duration, geographical scope,
activity or subject, it will be construed by limiting and reducing it, so as to be enforceable to the extent compatible with the applicable
law as it will then appear.

 

19.          Entire
Agreement. This Agreement constitutes the entire and only agreement between the Company
and me respecting the subject matter hereof, and supersedes all prior agreements and understandings, oral or written, between us concerning
such subject matter. No modification, amendment, waiver or termination of this Agreement or of any provision hereof will be binding unless
made in writing and signed by an authorized officer of the Company. Failure of the Company to insist upon strict compliance with any of
the terms, covenants or conditions hereof will not be deemed a waiver of such terms, covenants or conditions. In the event of any inconsistency
between this Agreement and any other contract between the Company and me, the provisions of this Agreement will prevail.

 

20.          Interpretation.
This Agreement will be deemed to be made and entered into in the Commonwealth of Massachusetts, and will in all respects be interpreted,
enforced and governed under the laws of the Commonwealth of Massachusetts. I hereby agree to consent to personal jurisdiction of the Suffolk
County Business Litigation Session for purposes of enforcing this Agreement, and waive any objection that I might have to personal jurisdiction
or venue in this court. As used in this Agreement, “including” means “including but not limited to”
