for the payment of money made payable to the order of “Signature Bank as Escrow Agent for Moleculin Biotech, Inc.,”
and Escrow Agent is willing to accept said checks and other instruments for the payment of money in accordance with the terms hereinafter

WHEREAS, the

WHEREAS, the
Company and Underwriter warrant to the Escrow Agent that a copy of each document that has been delivered to Investors and
third parties that include Escrow Agent’s name and duties, has been attached hereto as Schedule I.


 




     


     


    

 


NOW, THEREFORE,
IT IS AGREED as follows:


 


1.           Delivery
of Escrow Funds.


 


(a)          Underwriter
and the Company shall instruct Investors to deliver to Escrow Agent wire transfers to Signature Bank, 950 Third Avenue, 9th Floor,
New York, NY 10022, ABA No. 026013576 for credit to Signature Bank, as Escrow Agent for Moleculin Biotech, Inc., Account No. 1502647500,
in each case, with the name and address of the individual or entity making payment. The previous sentence notwithstanding, any
checks received by the Escrow Agent directly from investors or indirectly through an underwriter made payable to the order of “Signature
Bank, as Escrow Agent for Moleculin Biotech, Inc.” shall be dealt with as set forth below. In the event any Investor’s
address is not provided to Escrow Agent by the Investor, then Underwriter and/or the Company agree to promptly provide Escrow Agent
with such information in writing. The wire transfers and any such checks shall be deposited into a non interest-bearing account
at Signature Bank entitled “Moleculin Biotech, Inc., Signature Bank, as Escrow Agent” (the “Escrow Account”).


 


(b)          The
collected funds deposited into the Escrow Account are referred to as the “Escrow Funds.”


 


(c)          The
Escrow Agent shall have no duty or responsibility to enforce the collection or demand payment of any funds deposited into the Escrow
Account. If, for any reason, any check deposited into the Escrow Account shall be returned unpaid to the Escrow Agent, the sole
duty of the Escrow Agent shall be to return the check to the Investor and advise the Company and Underwriter promptly thereof.


 


2.           Release
of Escrow Funds. The Escrow Funds shall be paid by the Escrow Agent in accordance with the following:


 


(a)          In
the event that the Company and Underwriter advise the Escrow Agent in writing that the Offering has been terminated (the “Termination
Notice”), the Escrow Agent shall promptly return the funds paid by each Investor to said Investor without interest or
offset.


 


(b)          Reserved.


 


(c)          Provided
that the Escrow Agent does not receive the Termination Notice in accordance with Section 2(a) and there is the Minimum Amount deposited
into the Escrow Account on or prior to the Termination Date, the Escrow Agent shall, upon receipt of written instructions, in the
form of Exhibit A, attached hereto and made a part hereof, or in a form and substance satisfactory to the Escrow Agent, received
from the Company and Underwriter, pay the Escrow Funds in accordance with such written instructions, such payment or payments to
be made by wire transfer within one (1) business day of receipt of such written instructions. Such instructions must be received
by the Escrow Agent no later than 3:00 PM Eastern Time on a Banking Day for the Escrow Agent to process such instructions that
Banking Day.


 


(d)          If
by 3:00 P.M. Eastern time on the Termination Date, the Escrow Agent has not received written instructions from the Company and
Underwriter regarding the disbursement of the Escrow Funds or the total amount of the Escrow Funds is less than the Minimum Amount,
then the Escrow Agent shall promptly return the Escrow Funds to the Investors without interest or offset. The Escrow Funds returned
to each Investor shall be free and clear of any and all claims of the Escrow Agent.


 




    	 	2	 



     


    

 


(e)          The
Escrow Agent shall not be required to pay any uncollected funds or any funds that are not available for withdrawal.


 


(f)          If
the Termination Date or any date that is a deadline under this Agreement for giving the Escrow Agent notice or instructions or
for the Escrow Agent to take action is not a Banking Day, then such date shall be the Banking Day that immediately preceding that
date. A “Banking Day” is any day other than a Saturday, Sunday or a day that a New York State chartered bank
is not legally obligated to be opened.


 


3.            Acceptance
by Escrow Agent. The Escrow Agent hereby accepts and agrees to perform its obligations hereunder, provided that:


 


(a)          The
Escrow Agent may act in reliance upon any signature believed by it to be genuine, and may assume that any person who has been designated
by Underwriter or the Company to give any written instructions, notice or receipt, or make any statements in connection with the
provisions hereof has been duly authorized to do so. Escrow Agent shall have no duty to make inquiry as to the genuineness, accuracy
or validity of any statements or instructions or any signatures on statements or instructions. The names and true signatures of
each individual authorized to act singly on behalf of the Company and Underwriter are stated in Schedule II, which is attached
hereto and made a part hereof. The Company and Underwriter may each remove or add one or more of its authorized signers stated
on Schedule II by notifying the Escrow Agent of such change in accordance with this Agreement, which notice shall include
the true signature for any new authorized signatories.


 


(b)          The
Escrow Agent may act relative hereto in reliance upon advice of counsel in reference to any matter connected herewith. The Escrow
Agent shall not be liable for any mistake of fact or error of judgment or law, or for any acts or omissions of any kind, unless
caused by its willful misconduct or gross negligence.


 


(c)          Underwriter
and the Company agree to indemnify and hold the Escrow Agent harmless from and against any and all claims, losses, costs, liabilities,
damages, suits, demands, judgments or expenses (including but not limited to reasonable attorney’s fees) claimed against
or incurred by Escrow Agent arising out of or related, directly or indirectly, to this Escrow Agreement unless caused by the Escrow
Agent’s gross negligence or willful misconduct.


 


(d)          In
the event that the Escrow Agent shall be uncertain as to its duties or rights hereunder, the Escrow Agent shall be entitled to
(i) refrain from taking any action other than to keep safely the Escrow Funds until it shall be directed otherwise by a court of
competent jurisdiction, or (ii) deliver the Escrow Funds to a court of competent jurisdiction.


 




    	 	3	 



     


    

 


(e)          The
Escrow Agent shall have no duty, responsibility or obligation to interpret or enforce the terms of any agreement other than Escrow
Agent’s obligations hereunder, and the Escrow Agent shall not be required to make a request that any monies be delivered
to the Escrow Account, it being agreed that the sole duties and responsibilities of the Escrow Agent shall be to the extent not
prohibited by applicable law (i) to accept checks or other instruments for the payment of money and wire transfers delivered to
the Escrow Agent for the Escrow Account and deposit said checks and wire transfers into the non-interest bearing Escrow Account,
and (ii) to disburse or refrain from disbursing the Escrow Funds as stated above, provided that the checks received by the Escrow
Agent have been collected and are available for withdrawal.


 


4.            Escrow
Account Statements and Information. The Escrow Agent agrees to send to the Company and/or the Underwriter a copy of
the Escrow Account periodic statement, upon request in accordance with the Escrow Agent’s regular practices for providing
account statements to its non-escrow clients and to also provide the Company and/or Underwriter, or their designee, upon request
other deposit account information, including Escrow Account balances, by telephone or by computer communication, to the extent
practicable. The Company and Underwriter agree to complete and sign all forms or agreements required by the Escrow Agent for that
purpose. The Company and Underwriter each consent to the Escrow Agent’s release of such Escrow Account information to any
of the individuals designated by Company or Underwriter, which designation has been signed in accordance with Section 3(a) by any
of the persons in Schedule II.  Further, the Company and Underwriter have an option to receive e-mail notification
of incoming and outgoing wire transfers. If this e-mail notification service is requested and subsequently approved by the Escrow
Agent, the Company and Underwriter agrees to provide a valid e-mail address and other information necessary to set-up this service
and sign all forms and agreements required for such service. The Company and Underwriter each consent to the Escrow Agent’s
release of wire transfer information to the designated e-mail address(es). The Escrow Agent’s liability for failure to comply
with this section shall not exceed the cost of providing such information.


 


5.            Resignation
and Termination of the Escrow Agent. The Escrow Agent may resign at any time by giving 30 days’ prior written notice
of such resignation to Underwriter and the Company. Upon providing such notice, the Escrow Agent shall have no further obligation
hereunder except to hold as depositary the Escrow Funds that it receives until the end of such 30-day period. In such event, the
Escrow Agent shall not take any action, other than receiving and depositing Investors checks and wire transfers in accordance with
this Agreement, until the Company has designated a banking corporation, trust company, attorney or other person as successor. Upon
receipt of such written designation signed by Underwriter and the Company, the Escrow Agent shall promptly deliver the Escrow Funds
to such successor and shall thereafter have no further obligations hereunder. If such instructions are not received within 30 days
following the effective date of such resignation, then the Escrow Agent may deposit the Escrow Funds held by it pursuant to this
Agreement with a clerk of a court of competent jurisdiction pending the appointment of a successor. In either case provided for
in this Section, the Escrow Agent shall be relieved of all further obligations and released from all liability thereafter arising
with respect to the Escrow Funds.


 




    	 	4	 



     


    

 


6.            Termination.
The Company and Underwriter may terminate the appointment of the Escrow Agent hereunder upon written notice specifying the date
upon which such termination shall take effect, which date shall be at least 30 days from the date of such notice. In the event
of such termination, the Company and Underwriter shall, within 30 days of such notice, appoint a successor escrow agent and the
Escrow Agent shall, upon receipt of written instructions signed by the Company and Underwriter, turn over to such successor escrow
agent all of the Escrow Funds; provided, however, that if the Company and Underwriter fail to appoint a successor
escrow agent within such 30-day period, such termination notice shall be null and void and the Escrow Agent shall continue to be
bound by all of the provisions hereof. Upon receipt of the Escrow Funds, the successor escrow agent shall become the escrow agent
hereunder and shall be bound by all of the provisions hereof and Escrow Agent shall be relieved of all further obligations and
released from all liability thereafter arising with respect to the Escrow Funds and under this Agreement.


 


7.            Investment.
All funds received by the Escrow Agent shall be held only in non-interest bearing bank accounts at Signature Bank.


 


8.            Compensation.
Escrow Agent shall be entitled, for the duties to be performed by it hereunder, to a fee of $4,000.00, which fee shall be paid
by the Company upon the signing of this Agreement. In addition, the Company shall be obligated to reimburse Escrow Agent for all
fees, costs and expenses incurred or that become due in connection with this Agreement or the Escrow Account, including reasonable
attorney’s fees. Neither the modification, cancellation, termination or rescission of this Agreement nor the resignation
or termination of the Escrow Agent shall affect the right of Escrow Agent to retain the amount of any fee which has been paid,
or to be reimbursed or paid any amount which has been incurred or becomes due, prior to the effective date of any such modification,
cancellation, termination, resignation or rescission. To the extent the Escrow Agent has incurred any such expenses, or any such
fee becomes due, prior to any closing, the Escrow Agent shall advise the Company and the Company shall direct all such amounts
to be paid directly at any such closing.


 


9.            Notices.
All notices, requests, demands and other communications required or permitted to be given hereunder shall be in writing and shall
be deemed to have been duly given if sent by hand-delivery, by facsimile (followed by first-class mail), by nationally recognized
