tax, interest or penalty that may be imposed on you by Section 409A or damages for failing to comply with Section 409A.
A termination of your employment hereunder shall not be deemed to have occurred for purposes of any provision of this letter providing

409A and, for purposes of any such provision of this letter, references to a “termination,” “termination of
employment” or like terms shall mean “separation from service.” In the event that any payment or benefit made

shall be delayed until the six-month anniversary of the date of your “separation from service”. Each payment made
under this letter shall be designated as a “separate payment” within the meaning of Section 409A. All reimbursements

to reimbursement or in-kind benefits under this letter shall not be subject to liquidation or exchange for another benefit and

expenses eligible for reimbursement, or in-kind benefits to be provided, respectively, in any other taxable year.

COVENANT AGREEMENT

CONFIDENTIALITY,
RESTRICTIVE COVENANT

AND
INTELLECTUAL PROPERTY AGREEMENT

 

As
a condition of my employment and/or continued employment with Marina Biotech, Inc., its subsidiaries, affiliates, successors or
assigns (collectively, the “Company”), and in consideration of my employment with the Company and my receipt
of the compensation now and hereafter paid to me by the Company, I, Larn Hwang, Ph.D., agree to the following (the “Agreement”):

 

1.       Confidential
Information. I agree that I have had access to the Company’s Confidential Information, as defined herein, that such
Confidential Information is valuable to the Company, and that the unauthorized release of that information would cause serious
damage to the Company. I therefore agree to hold in strictest confidence, and not to use, except for the benefit of the Company,
or to disclose to any person, firm or corporation without written authorization of the Company, any Confidential Information of
the Company. I understand that “Confidential Information” means any of the Company’s proprietary information,
technical data, trade secrets or know-how, including but not limited to, sketches and drawings, research, product plans, products,
services, customer lists and customers, markets, software, developments, inventions, processes, formulas, technology, engineering,
marketing, finances, business plans, or other business information disclosed to me by the Company either directly or indirectly
in writing, orally or by drawings or observation. In the event that I am required by law to disclose any Confidential Information,
I will give the Company prompt advance written notice thereof and will assist the Company in obtaining an order to protect the
Confidential Information from public disclosure.

 

2.       Inventions

 

(a)       Inventions
Retained and Licensed. I have attached hereto, as Exhibit A, a list describing all inventions, designs, original
works of authorship, developments, improvements, and trade secrets which were made by me prior to my employment with the Company
(collectively referred to as “Prior Inventions”), which belong to me, which relate to the Company’s business,
products or product development, and which are not assigned to the Company hereunder. If there are no such Prior Inventions indicated
on Exhibit A, I represent that there are no such Prior Inventions. If in the course of providing services to the Company,
I incorporate into a Company product, process or design a Prior Invention owned by me or in which I have an interest, the Company
is hereby granted and shall have a nonexclusive, royalty-free, irrevocable, perpetual, worldwide license to make, have made, modify,
use and sell such Prior Invention as part of or in connection with such product, process or design.

 

(b)       Assignment
of Inventions. I acknowledge that during my employment with the Company and/or during such time as I am providing services
to the Company as a consultant, contractor, or in any capacity (both my employment and/or my provision of services are referred
to collectively herein as “employment” or being “employed”), I may be expected to undertake creative work,
either alone or jointly with others, which may lead to inventions, original works of authorship, developments, concepts, improvements,
trade secrets or other intellectual property rights, whether or not patentable or registrable under copyright or similar laws
(“Inventions”). I hereby agree that all Inventions created while employed by the Company (whether or not on
the Company’s premises or using the Company’s equipment and materials or during regular business hours), and in connection
with my employment by the Company, shall be a work-for-hire and shall be the sole and exclusive property of the Company, and I
hereby assign to the Company all of my right, title and interest in and to any and all such Inventions. In addition, any Inventions
created after the termination of my employment with the Company which are based upon or derived from Confidential Information
shall be the sole and exclusive property of the Company, and I hereby assign to the Company all of my right, title and interest
in and to any and all such Inventions.

 

    	 

    	 

    

 

(c)       Patent
and Copyright Registrations. I agree to assist the Company, or its designee, in every way, to secure the Company’s
rights in the Inventions and any copyrights, patents, mask work rights or other intellectual property rights relating thereto
in any and all countries, including the disclosure to the Company of all pertinent information and data with respect thereto,
the execution of all applications, specifications, oaths, assignments and all other instruments which the Company shall deem necessary
in order to apply for and obtain such rights and in order to assign and convey to the Company, its successors, assigns and nominees
the sole and exclusive rights, title and interest in and to such Inventions, and any copyrights, patents, mask work rights or
other intellectual property rights relating thereto. I further agree that my obligation to execute or cause to be executed any
such instrument or papers shall continue after the termination of this Agreement.

 

(d)       Application.
I agree that the provisions of this Section 2 shall apply with respect to any and all Inventions, whether created during my employment
with the Company or any predecessor entity, or during any pre-organization period that directly apply to the Company’s business
as of the date of creation. I acknowledge that the Company and its future investors shall rely on this representation.

 

3.       Returning
Company Documents. I agree that, at the time I cease performing services for the Company, I will immediately deliver to
the Company (and will not keep in my possession, recreate or deliver to anyone else) any and all software, devices, records, data,
notes, reports, proposals, lists, correspondence, specifications, drawings, blueprints, sketches, materials, equipment, other
documents or property, including all Confidential Information, or reproductions of any aforementioned items developed by me in
connection with my employment with the Company or otherwise belonging to the Company, its successors or assigns.

 

4.       Non-Solicitation/Non-Service

 

(a)      Non-Solicit.
To the extent permitted by law, I agree that while I am employed by the Company and for a period of twelve (12) months
immediately following the termination of my employment from the Company for any reason, I shall not either directly or
indirectly:

 

(i)
       hire, solicit, induce,
recruit or encourage any of the Company’s employees or independent contractors to leave their employment or end
their relationship with the Company, or take away such employees or independent contractors, or attempt to solicit, induce,
recruit, encourage or take away employees and independent contractors of the Company, either for myself or for any other
person or entity; or

 

    	 	 2	 

    	 

    

 

(ii)
       solicit, induce, or attempt to solicit or induce any customer, vendor or client
of the Company to terminate his, her or its relationship with the Company or to encourage said customer, vendor or client to use
my services or those provided by an entity with which I am employed or affiliated to the detriment of the Company.

 

(b)       Non-Service.
To the extent permitted by law, I agree that while I am employed by the Company and for a period of twelve (12) months immediately
following the termination of my employment from the Company for any reason, I shall not, directly or indirectly, on my own behalf
or on behalf of any person, firm, company, or entity, provide services or accept business of the type offered by the Company to
any entity that:

 

(i)
is a client, customer, or business partner of the Company; and/or

 

(ii)
was a client, customer, or business partner of the Company within the two year period preceding the termination of my employment
with the Company; and/or

 

(iii)
was a prospective client, customer, or business partner of the Company during the two year period preceding the termination of
my employment with the Company and which the Company has materially pursued or otherwise made material efforts in developing such
prospective relationship as of the termination date.

 

(c)       Reasonableness/Judicial
Reformation. I agree that the restrictive covenants in this section are reasonable under the circumstances, and I further
agree that if, in the opinion of any court of competent jurisdiction, such restraint is not reasonable in any respect, such court
shall have the right, power and authority to excise or modify such provision or provisions of these covenants as to the court
shall appear not reasonable and to enforce the remainder of the covenants as so amended.

 

5.       Non-Disparagement.
I agree that I will not, directly or indirectly, individually or in concert with others, engage in any conduct or make any statement
that is likely to have the effect of undermining or disparaging the reputation of the Company, or its good will, products, or
business opportunities, or that is likely to have the effect of undermining or disparaging the reputation of any officer, director,
agent, representative, shareholder or employee, past or present, of the Company.

 

6.       Equitable
Relief & Remedies. I agree that it would be impossible or inadequate to measure and calculate the Company’s
damages from any breach of the covenants set forth herein. Accordingly, I agree that if I breach any of the covenants contained
herein, the Company will have available, in addition to any other right or remedy available, the right to cease making any payments
otherwise due to me (to the extent permitted by law) and the right to obtain an injunction from a court of competent jurisdiction
restraining such breach or threatened breach and to specific performance of any such provision of this Agreement. I agree that
the time periods of the restrictive covenants contained herein shall be extended by any and all periods during which I am in breach
of such restrictive covenants.

 

    	 	 3	 

    	 

    

 

7.       General
Provisions

 

(a)       Severability.
I agree that if one or more of the provisions in this Agreement are deemed void by law, then the remaining provisions will continue
in full force and effect and, if legally permitted, such offending provision or provisions shall be replaced with an enforceable
provision or enforceable provisions that as nearly as possible effects the parties’ intent. Without limiting the generality
of the foregoing, the parties hereby expressly state their intent that, to the extent any provision of this Agreement is unenforceable
due to the scope (temporal, geographic or otherwise) being too broad, the court or arbitrator properly adjudicating any dispute
with respect thereto shall modify such provision to the minimum extent necessary to cause such provision to be enforceable.

 

(b)       Successors
and Assigns. This Agreement will be binding upon my heirs, executors, administrators and other legal representatives and
will be for the benefit of the Company, its successors, and its assigns. I acknowledge and agree that I cannot assign or transfer
this Agreement nor any rights hereunder without the express written consent of the Company, in its absolute discretion. The Company,
however, shall have the right to assign this Agreement and/or any of its rights or obligations set forth herein.

 

(c)       Survival.
I agree that notwithstanding anything in this Agreement to the contrary, the provisions of this Agreement shall survive any termination
of my employment with the Company and/or termination of this Agreement, and shall remain in full force and effect indefinitely.

 

(d)       Governing
Law. This Agreement shall be construed, interpreted and governed in accordance with the laws of the State of California,
without reference to rules relating to conflicts of law.

 

(e)       Amendment.
This Agreement may only be amended by written agreement of the parties hereto.

tax, interest or penalty that may be imposed on you by Section 409A or damages for failing to comply with Section 409A. A termination
of your employment hereunder shall not be deemed to have occurred for purposes of any provision of this letter providing for the
payment of any amount or benefit constituting “deferred compensation” under Section 409A upon or following a termination
of employment unless such termination is also a “separation from service” within the meaning of Section 409A and,
for purposes of any such provision of this letter, references to a “termination,” “termination of employment”
or like terms shall mean “separation from service.” In the event that any payment or benefit made hereunder or under
any compensation plan, program or arrangement of the Company would constitute payments or benefits pursuant to a non-qualified
deferred compensation plan within the meaning of Section 409A and, at the time of your “separation from service” you
are a “specified employee” within the meaning of Section 409A, then any such payments or benefits shall be delayed
until the six-month anniversary of the date of your “separation from service”. Each payment made under this letter
shall be designated as a “separate payment” within the meaning of Section 409A. All reimbursements and in-kind benefits
provided under this letter shall be made or provided in accordance with the requirements of Section 409A to the extent that such
reimbursements or in-kind benefits are subject to Section 409A. All reimbursements for expenses paid pursuant hereto that constitute
taxable income to you shall in no event be paid later than the end of the calendar year next following the calendar year in which
you incur such expense or pays such related tax. Unless otherwise permitted by Section 409A, the right to reimbursement or in-kind
benefits under this letter shall not be subject to liquidation or exchange for another benefit and the amount of expenses eligible
for reimbursement, or in-kind benefits, provided during any taxable year shall not affect the expenses eligible for reimbursement,
or in-kind benefits to be provided, respectively, in any other taxable year.

RESTRICTIVE
COVENANT AGREEMENT

 

    	 	6 	 

    	 

    

 

CONFIDENTIALITY,
RESTRICTIVE COVENANT

AND
INTELLECTUAL PROPERTY AGREEMENT

 

As
a condition of my employment and/or continued employment with Marina Biotech, Inc., its subsidiaries, affiliates, successors or
assigns (collectively, the “Company”), and in consideration of my employment with the Company and my receipt
of the compensation now and hereafter paid to me by the Company, I, Mihir Munsif, agree to the following (the “Agreement”):

 

1.       Confidential
Information. I agree that I have had access to the Company’s Confidential Information, as defined herein, that such
Confidential Information is valuable to the Company, and that the unauthorized release of that information would cause serious
damage to the Company. I therefore agree to hold in strictest confidence, and not to use, except for the benefit of the Company,
or to disclose to any person, firm or corporation without written authorization of the Company, any Confidential Information of
the Company. I understand that “Confidential Information” means any of the Company’s proprietary information,
technical data, trade secrets or know-how, including but not limited to, sketches and drawings, research, product plans, products,
services, customer lists and customers, markets, software, developments, inventions, processes, formulas, technology, engineering,
marketing, finances, business plans, or other business information disclosed to me by the Company either directly or indirectly
in writing, orally or by drawings or observation. In the event that I am required by law to disclose any Confidential Information,
I will give the Company prompt advance written notice thereof and will assist the Company in obtaining an order to protect the
Confidential Information from public disclosure.

 

2.       Inventions

 

(a)       Inventions
Retained and Licensed. I have attached hereto, as Exhibit A, a list describing all inventions, designs, original
works of authorship, developments, improvements, and trade secrets which were made by me prior to my employment with the Company
(collectively referred to as “Prior Inventions”), which belong to me, which relate to the Company’s business,
products or product development, and which are not assigned to the Company hereunder. If there are no such Prior Inventions indicated
on Exhibit A, I represent that there are no such Prior Inventions. If in the course of providing services to the Company,
I incorporate into a Company product, process or design a Prior Invention owned by me or in which I have an interest, the Company
is hereby granted and shall have a nonexclusive, royalty-free, irrevocable, perpetual, worldwide license to make, have made, modify,
use and sell such Prior Invention as part of or in connection with such product, process or design.

 

(b)       Assignment
of Inventions. I acknowledge that during my employment with the Company and/or during such time as I am providing services
to the Company as a consultant, contractor, or in any capacity (both my employment and/or my provision of services are referred
to collectively herein as “employment” or being “employed”), I may be expected to undertake creative work,
either alone or jointly with others, which may lead to inventions, original works of authorship, developments, concepts, improvements,
trade secrets or other intellectual property rights, whether or not patentable or registrable under copyright or similar laws
(“Inventions”). I hereby agree that all Inventions created while employed by the Company (whether or not on
the Company’s premises or using the Company’s equipment and materials or during regular business hours), and in connection
with my employment by the Company, shall be a work-for-hire and shall be the sole and exclusive property of the Company, and I
hereby assign to the Company all of my right, title and interest in and to any and all such Inventions. In addition, any Inventions
created after the termination of my employment with the Company which are based upon or derived from Confidential Information
shall be the sole and exclusive property of the Company, and I hereby assign to the Company all of my right, title and interest
in and to any and all such Inventions.

 

    	 	 	 

    	 

    

 

(c)       Patent
and Copyright Registrations. I agree to assist the Company, or its designee, in every way, to secure the Company’s
rights in the Inventions and any copyrights, patents, mask work rights or other intellectual property rights relating thereto
in any and all countries, including the disclosure to the Company of all pertinent information and data with respect thereto,
the execution of all applications, specifications, oaths, assignments and all other instruments which the Company shall deem necessary
in order to apply for and obtain such rights and in order to assign and convey to the Company, its successors, assigns and nominees
the sole and exclusive rights, title and interest in and to such Inventions, and any copyrights, patents, mask work rights or
other intellectual property rights relating thereto. I further agree that my obligation to execute or cause to be executed any
such instrument or papers shall continue after the termination of this Agreement.

 

(d)       Application.
I agree that the provisions of this Section 2 shall apply with respect to any and all Inventions, whether created during my employment
with the Company or any predecessor entity, or during any pre-organization period that directly apply to the Company’s business
as of the date of creation. I acknowledge that the Company and its future investors shall rely on this representation.

 

3.       Returning
Company Documents. I agree that, at the time I cease performing services for the Company, I will immediately deliver to
the Company (and will not keep in my possession, recreate or deliver to anyone else) any and all software, devices, records, data,
notes, reports, proposals, lists, correspondence, specifications, drawings, blueprints, sketches, materials, equipment, other
documents or property, including all Confidential Information, or reproductions of any aforementioned items developed by me in
connection with my employment with the Company or otherwise belonging to the Company, its successors or assigns.

 

4.       Non-Solicitation/Non-Service

 

(a)      Non-Solicit.
To the extent permitted by law, I agree that while I am employed by the Company and for a period of twelve (12) months immediately
following the termination of my employment from the Company for any reason, I shall not either directly or indirectly:

 

(i)
       hire, solicit, induce, recruit
or encourage any of the Company’s employees or independent contractors to leave their employment or end their relationship
with the Company, or take away such employees or independent contractors, or attempt to solicit, induce, recruit, encourage or
take away employees and independent contractors of the Company, either for myself or for any other person or entity; or

 

    	 	2 	 

    	 

    

 

(ii)
      solicit, induce, or attempt to solicit or induce any customer, vendor or client
of the Company to terminate his, her or its relationship with the Company or to encourage said customer, vendor or client to use
my services or those provided by an entity with which I am employed or affiliated to the detriment of the Company.

 

(b)      Non-Service.
To the extent permitted by law, I agree that while I am employed by the Company and for a period of twelve (12) months immediately
following the termination of my employment from the Company for any reason, I shall not, directly or indirectly, on my own behalf
or on behalf of any person, firm, company, or entity, provide services or accept business of the type offered by the Company to
any entity that:

 

(i)
is a client, customer, or business partner of the Company; and/or

 

(ii)
was a client, customer, or business partner of the Company within the two year period preceding the termination of my employment
with the Company; and/or

 

(iii)
was a prospective client, customer, or business partner of the Company during the two year period preceding the termination of
my employment with the Company and which the Company has materially pursued or otherwise made material efforts in developing such
prospective relationship as of the termination date.

 

(c)       Reasonableness/Judicial
Reformation. I agree that the restrictive covenants in this section are reasonable under the circumstances, and I further
agree that if, in the opinion of any court of competent jurisdiction, such restraint is not reasonable in any respect, such court
shall have the right, power and authority to excise or modify such provision or provisions of these covenants as to the court
shall appear not reasonable and to enforce the remainder of the covenants as so amended.

 

5.       Non-Disparagement.
I agree that I will not, directly or indirectly, individually or in concert with others, engage in any conduct or make any statement
that is likely to have the effect of undermining or disparaging the reputation of the Company, or its good will, products, or
business opportunities, or that is likely to have the effect of undermining or disparaging the reputation of any officer, director,
agent, representative, shareholder or employee, past or present, of the Company.

 

6.       Equitable
Relief & Remedies. I agree that it would be impossible or inadequate to measure and calculate the Company’s
damages from any breach of the covenants set forth herein. Accordingly, I agree that if I breach any of the covenants contained
herein, the Company will have available, in addition to any other right or remedy available, the right to cease making any payments
otherwise due to me (to the extent permitted by law) and the right to obtain an injunction from a court of competent jurisdiction
restraining such breach or threatened breach and to specific performance of any such provision of this Agreement. I agree that
the time periods of the restrictive covenants contained herein shall be extended by any and all periods during which I am in breach
of such restrictive covenants.

 

    	 	3 	 

    	 

    

 

7.       General
Provisions

 

(a)       Severability.
I agree that if one or more of the provisions in this Agreement are deemed void by law, then the remaining provisions will continue
in full force and effect and, if legally permitted, such offending provision or provisions shall be replaced with an enforceable
provision or enforceable provisions that as nearly as possible effects the parties’ intent. Without limiting the generality
of the foregoing, the parties hereby expressly state their intent that, to the extent any provision of this Agreement is unenforceable
due to the scope (temporal, geographic or otherwise) being too broad, the court or arbitrator properly adjudicating any dispute
with respect thereto shall modify such provision to the minimum extent necessary to cause such provision to be enforceable.

 

(b)       Successors
and Assigns. This Agreement will be binding upon my heirs, executors, administrators and other legal representatives and
will be for the benefit of the Company, its successors, and its assigns. I acknowledge and agree that I cannot assign or transfer
this Agreement nor any rights hereunder without the express written consent of the Company, in its absolute discretion. The Company,
however, shall have the right to assign this Agreement and/or any of its rights or obligations set forth herein.

 

(c)       Survival.
I agree that notwithstanding anything in this Agreement to the contrary, the provisions of this Agreement shall survive any termination
of my employment with the Company and/or termination of this Agreement, and shall remain in full force and effect indefinitely.

 

(d)       Governing
Law. This Agreement shall be construed, interpreted and governed in accordance with the laws of the State of California,
without reference to rules relating to conflicts of law.

 

(e)       Amendment.
This Agreement may only be amended by written agreement of the parties hereto.
