<P STYLE="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0; text-align: justify; text-indent: 0.5in">On February 16, 2018,
Moleculin Biotech, Inc. (the &ldquo;Company&rdquo;) entered into a Securities Purchase Agreement (the &ldquo;Purchase Agreement&rdquo;)
with certain institutional investors (the &ldquo;Investors&rdquo;) for the sale by the Company of 4,290,000 shares (the &ldquo;Common
Shares&rdquo;) of the Company&rsquo;s common stock (the &ldquo;Common Stock&rdquo;), at a purchase price of $2.10 per share. Concurrently
with the sale of the Common Shares, pursuant to the Purchase Agreement the Company also sold warrants to purchase 2,145,000 shares
of Common Stock (the &ldquo;Warrants&rdquo;). The Company sold the Common Shares and Warrants for aggregate gross proceeds of approximately
$9.0 million. Subject to certain beneficial ownership limitations, the Warrants will be initially exercisable on the six-month
anniversary of the issuance date at an exercise price equal to $2.80 per share of Common Stock, subject to adjustments as provided
under the terms of the Warrants. The Warrants are exercisable for five years from the initial exercise date. The closing of the
sales of these securities under the Purchase Agreement is expected to occur on February 21, 2018.</P>

<P STYLE="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0; text-align: justify">&nbsp;</P>

<P STYLE="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0; text-align: justify; text-indent: 0.5in">The Company estimates
that the net proceeds from the transactions will be approximately $8.27 million after deducting certain fees due to the placement
agent and the Company&rsquo;s estimated transaction expenses. The net proceeds received by the Company from the transactions will
be used for its planned clinical trials, preclinical programs, for other research and development activities and for general corporate
purposes.</P>

<P STYLE="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0; text-align: justify">&nbsp;</P>

<P STYLE="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0; text-align: justify; text-indent: 0.5in">The Common Shares were
offered and sold by the Company pursuant to an effective shelf registration statement on Form S-3, which was filed with the Securities
and Exchange Commission (the &ldquo;SEC&rdquo;) on July 24, 2017 and subsequently declared effective on August 21, 2017 (File No.
333-219434) (the &ldquo;Registration Statement&rdquo;), and the base prospectus contained therein. The Company expects to file
a prospectus supplement with the SEC on February 16, 2018 in connection with the sale of the Common Shares.</P>

<P STYLE="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0; text-align: justify">&nbsp;</P>

<P STYLE="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0; text-align: justify; text-indent: 0.5in">The Warrants and the
shares issuable upon exercise of the Warrants were sold without registration under the Securities Act of 1933 (the &ldquo;Securities
Act&rdquo;) in reliance on the exemptions provided by Section 4(a)(2) of the Securities Act as transactions not involving a public
offering and Rule 506 promulgated under the Securities Act as sales to accredited investors, and in reliance on similar exemptions
under applicable state laws.</P>

<P STYLE="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0; text-align: justify">&nbsp;</P>

<P STYLE="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0; text-align: justify; text-indent: 0.5in">The representations,
warranties and covenants contained in the Purchase Agreement were made solely for the benefit of the parties to the Purchase Agreement.
In addition, such representations, warranties and covenants (i) are intended as a way of allocating the risk between the parties
to the Purchase Agreement and not as statements of fact, and (ii) may apply standards of materiality in a way that is different
from what may be viewed as material by stockholders of, or other investors in, the Company. Accordingly, the Purchase Agreement
is included with this filing only to provide investors with information regarding the terms of transaction, and not to provide
investors with any other factual information regarding the Company. Stockholders should not rely on the representations, warranties
and covenants or any descriptions thereof as characterizations of the actual state of facts or condition of the Company or any
of its subsidiaries or affiliates. Moreover, information concerning the subject matter of the representations and warranties may
change after the date of the Purchase Agreement, which subsequent information may or may not be fully reflected in public disclosures.</P>

into a placement agent agreement (the &ldquo;Placement Agency Agreement&rdquo;) with Roth Capital Partners, LLC (&ldquo;Roth&rdquo;),
pursuant to which Roth agreed to serve as exclusive placement agent for the issuance and sale of the Common Shares and Warrants.
The Company has agreed to pay Roth an aggregate fee equal to 6.5% of the gross proceeds received by the Company from the sale of
the securities in the transactions. Pursuant to the Placement Agency Agreement, the Company also agreed to grant to Roth or its
designees warrants to purchase up to 3% of the aggregate number of shares of Common Stock sold in the transactions (the &ldquo;Roth
Warrants&rdquo;). The Roth Warrants have substantially the same terms as the Warrants, except that the Roth Warrants will expire
on February 15, 2023. The Roth Warrants and the shares issuable upon exercise of the Roth Warrants will be issued in reliance on
the exemption from registration provided by Section 4(a)(2) of the Securities Act as transactions not involving a public offering
and in reliance on similar exemptions under applicable state laws. The Company will also reimburse Roth for its expenses of $75,000.</P>

<P STYLE="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0; text-align: justify; text-indent: 0.5in">Subject to the consummation
of the offering, the Company agreed to give Roth a nine-month right of first refusal to act as the Company&rsquo;s lead underwriter
or exclusive placement agent for any further capital raising transactions undertaken by the Company. With certain exceptions, the
Company also granted Roth a six-month tail fee equal to the cash and warrant compensation in the offering, if any investor with
which Roth had substantive discussions with respect to the offering, provides the Company with further capital during such six-month
period following termination of the Company&rsquo;s engagement of Roth.</P>

to ensure that information required to be disclosed by the Company in the reports it files or submits under the Exchange Act is

copy or PDF copy submitted by e-mail (or e-mail attachment) of the Notice of Exercise in the form annexed hereto (the &ldquo;<U>Notice

Settlement Period (as defined in Section 2(d)(i) herein) following the date of exercise as aforesaid, the Holder shall deliver
the aggregate Exercise Price for the shares specified in the applicable Notice of Exercise by wire transfer or cashier&rsquo;s
check drawn on a United States bank unless the cashless exercise procedure specified in Section 2(c) below is specified in the
applicable Notice of Exercise. No ink-original Notice of Exercise shall be required, nor shall any medallion guarantee (or other
type of guarantee or notarization) of any Notice of Exercise be required. Notwithstanding anything herein to the contrary, the
Holder shall not be required to physically surrender this Warrant to the Company until the Holder has purchased all of the Warrant
Shares available hereunder and the Warrant has been exercised in full, in which case, the Holder shall surrender this Warrant to
the Company for cancellation within three (3) Trading Days of the date on which the final Notice of Exercise is delivered to the
Company. Partial exercises of this Warrant resulting in purchases of a portion of the total number of Warrant Shares available
hereunder shall have the effect of lowering the outstanding number of Warrant Shares purchasable hereunder in an amount equal to
the applicable number of Warrant Shares purchased. The Holder and the Company shall maintain records showing the number of Warrant
Shares purchased and the date of such purchases. The Company shall deliver any objection to any Notice of Exercise within one (1)

purchased exceeds (y) the amount obtained by multiplying (1) the number of Warrant Shares that the Company was required to deliver
to the Holder in connection with the exercise at issue times (2) the price at which the sell order giving rise to such purchase
obligation was executed, and (B) at the option of the Holder, either reinstate the portion of the Warrant and equivalent number
of Warrant Shares for which such exercise was not honored (in which case such exercise shall be deemed rescinded) or deliver to
the Holder the number of shares of Common Stock that would have been issued had the Company timely complied with its exercise
and delivery obligations hereunder. For example, if the Holder purchases Common Stock having a total purchase price of $11,000
to cover a Buy-In with respect to an attempted exercise of shares of Common Stock with an aggregate sale price giving rise to
such purchase obligation of $10,000, under clause (A) of the immediately preceding sentence the Company shall be required to pay
the Holder $1,000. The Holder shall provide the Company written notice indicating the amounts payable to the Holder in respect
of the Buy-In and, upon request of the Company, evidence of the amount of such loss. Nothing herein shall limit a Holder&rsquo;s
right to pursue any other remedies available to it hereunder, at law or in equity including, without limitation, a decree of specific
performance and/or injunctive relief with respect to the Company&rsquo;s failure to timely deliver shares of Common Stock upon
exercise of the Warrant as required pursuant to the terms hereof.</P>

Persons acting as a group together with the Holder or any of the Holder&rsquo;s Affiliates (such Persons, &ldquo;<U>Attribution
Parties</U>&rdquo;)), would beneficially own in excess of the Beneficial Ownership Limitation (as defined below).&nbsp; For purposes
of the foregoing sentence, the number of shares of Common Stock beneficially owned by the Holder and its Affiliates and Attribution
Parties shall include the number of shares of Common Stock issuable upon exercise of this Warrant with respect to which such determination
is being made, but shall exclude the number of shares of Common Stock which would be issuable upon (i) exercise of the remaining,

to the Holder that such calculation is in compliance with Section 13(d) of the Exchange Act and the Holder is solely responsible

applies, the determination of whether this Warrant is exercisable (in relation to other securities owned by the Holder together
with any Affiliates and Attribution Parties) and of which portion of this Warrant is exercisable shall be in the sole discretion
of the Holder, and the submission of a Notice of Exercise shall be deemed to be the Holder&rsquo;s determination of whether this
Warrant is exercisable (in relation to other securities owned by the Holder together with any Affiliates and Attribution Parties)
and of which portion of this Warrant is exercisable, in each case subject to the Beneficial Ownership Limitation, and the Company
shall have no obligation to verify or confirm the accuracy of such determination. In addition, a determination as to any group
status as contemplated above shall be determined in accordance with Section 13(d) of the Exchange Act and the rules and regulations
promulgated thereunder. For purposes of this Section 2(e), in determining the number of outstanding shares of Common Stock, a Holder
may rely on the number of outstanding shares of Common Stock as reflected in (A) the Company&rsquo;s most recent periodic or annual
report filed with the Commission, as the case may be, (B) a more recent public announcement by the Company or (C) a more recent
written notice by the Company or the Transfer Agent setting forth the number of shares of Common Stock outstanding.&nbsp; Upon
the written or oral request of a Holder, the Company shall within one Trading Day confirm orally and in writing to the Holder the
number of shares of Common Stock then outstanding.&nbsp; In any case, the number of outstanding shares of Common Stock shall be
determined after giving effect to the conversion or exercise of securities of the Company, including this Warrant, by the Holder
or its Affiliates or Attribution Parties since the date as of which such number of outstanding shares of Common Stock was reported.
The &ldquo;<U>Beneficial Ownership Limitation</U>&rdquo; shall be [4.99%] [9.99%]of the number of shares of the Common Stock outstanding
immediately after giving effect to the issuance of shares of Common Stock issuable upon exercise of this Warrant. The Holder, upon
notice to the Company, may increase or decrease the Beneficial Ownership Limitation provisions of this Section 2(e), provided that
the Beneficial Ownership Limitation in no event exceeds 9.99% of the number of shares of the Common Stock outstanding immediately
after giving effect to the issuance of shares of Common Stock upon exercise of this Warrant held by the Holder and the provisions

such exercise immediately prior to the occurrence of such Fundamental Transaction, at the option of the Holder (without regard
to any limitation in Section 2(e) on the exercise of this Warrant), the number of shares of Common Stock of the successor or acquiring
corporation or of the Company, if it is the surviving corporation, and any additional consideration (the &ldquo;<U>Alternate Consideration</U>&rdquo;)
receivable as a result of such Fundamental Transaction by a holder of the number of shares of Common Stock for which this Warrant
is exercisable immediately prior to such Fundamental Transaction (without regard to any limitation in Section 2(e) on the exercise
of this Warrant). For purposes of any such exercise, the determination of the Exercise Price shall be appropriately adjusted to
apply to such Alternate Consideration based on the amount of Alternate Consideration issuable in respect of one share of Common
Stock in such Fundamental Transaction, and the Company shall apportion the Exercise Price among the Alternate Consideration in
a reasonable manner reflecting the relative value of any different components of the Alternate Consideration. If holders of Common
Stock are given any choice as to the securities, cash or property to be received in a Fundamental Transaction, then the Holder
shall be given the same choice as to the Alternate Consideration it receives upon any exercise of this Warrant following such Fundamental
Transaction. Notwithstanding anything to the contrary, in the event of a Fundamental Transaction, the Company or any Successor
Entity (as defined below) shall, at the Holder&rsquo;s option, exercisable at any time concurrently with, or within 30 days after,
the consummation of the Fundamental Transaction (or, if later, the date of the public announcement of the applicable Fundamental
Transaction), purchase this Warrant from the Holder by paying to the Holder an amount of cash equal to the Black Scholes Value
of the remaining unexercised portion of this Warrant on the date of the consummation of such Fundamental Transaction; <U>provided</U>,
<U>however</U>, that, if the Fundamental Transaction is not within the Company's control, including not approved by the Company's
Board of Directors, Holder shall only be entitled to receive from the Company or any Successor Entity, as of the date of consummation
of such Fundamental Transaction, the same type or form of consideration (and in the same proportion), at the Black Scholes Value
(as defined below) of the unexercised portion of this Warrant, that is being offered and paid to the holders of Common Stock of
the Company in connection with the Fundamental Transaction, whether that consideration be in the form of cash, stock or any combination
thereof, or whether the holders of Common Stock are given the choice to receive from among alternative forms of consideration in
connection with the Fundamental Transaction. &ldquo;<U>Black Scholes Value</U>&rdquo; means the value of this Warrant based on
the Black Scholes Option Pricing Model obtained from the &ldquo;OV&rdquo; function on Bloomberg, L.P. (&ldquo;<U>Bloomberg</U>&rdquo;)
determined as of the day of consummation of the applicable Fundamental Transaction for pricing purposes and reflecting (A) a risk-free
interest rate corresponding to the U.S. Treasury rate for a period equal to the time between the date of the public announcement
of the applicable Fundamental Transaction and the Termination Date, (B) an expected volatility equal to the greater of 100% and
the 100 day volatility obtained from the HVT function on Bloomberg as of the Trading Day immediately following the public announcement
of the applicable Fundamental Transaction, (C) the underlying price per share used in such calculation shall be the greater of
(i) the sum of the price per share being offered in cash, if any, plus the value of any non-cash consideration, if any, being offered
in such Fundamental Transaction and (ii) the greater of (x) the last VWAP immediately prior to the public announcement of such
Fundamental Transaction and (y) the last VWAP immediately prior to the consummation of such Fundamental Transaction and (D) a remaining
option time equal to the time between the date of the public announcement of the applicable Fundamental Transaction and the Termination
Date. The payment of the Black Scholes Value will be made by wire transfer of immediately available funds within five Business
Days of the Holder&rsquo;s election (or, if later, on the effective date of the Fundamental Transaction). The Company shall cause
any successor entity in a Fundamental Transaction in which the Company is not the survivor (the &ldquo;<U>Successor Entity</U>&rdquo;)
to assume in writing all of the obligations of the Company under this Warrant and the other Transaction Documents in accordance
with the provisions of this Section 3(e) pursuant to written agreements in form and substance reasonably satisfactory to the Holder
and approved by the Holder (without unreasonable delay) prior to such Fundamental Transaction and shall, at the option of the Holder,
deliver to the Holder in exchange for this Warrant a security of the Successor Entity evidenced by a written instrument substantially
similar in form and substance to this Warrant which is exercisable for a corresponding number of shares of capital stock of such
Successor Entity (or its parent entity) equivalent to the shares of Common Stock acquirable and receivable upon exercise of this
Warrant (without regard to any limitations on the exercise of this Warrant) prior to such Fundamental Transaction, and with an
exercise price which applies the exercise price hereunder to such shares of capital stock (but taking into account the relative
value of the shares of Common Stock pursuant to such Fundamental Transaction and the value of such shares of capital stock, such
number of shares of capital stock and such exercise price being for the purpose of protecting the economic value of this Warrant
immediately prior to the consummation of such Fundamental Transaction), and which is reasonably satisfactory in form and substance
to the Holder. Upon the occurrence of any such Fundamental Transaction, the Successor Entity shall succeed to, and be substituted
for (so that from and after the date of such Fundamental Transaction, the provisions of this Warrant and the other Transaction
Documents referring to the &ldquo;Company&rdquo; shall refer instead to the Successor Entity), and may exercise every right and
power of the Company and shall assume all of the obligations of the Company under this Warrant and the other Transaction Documents
with the same effect as if such Successor Entity had been named as the Company herein. For the avoidance of doubt, if, at any time
while this Warrant is outstanding, a Fundamental Transaction occurs, pursuant to the terms of this Section 3(e), the Holder shall
not be entitled to receive more than one of (i) the consideration receivable as a result of such Fundamental Transaction by a holder
of the number of shares of Common Stock for which this Warrant is exercisable immediately prior to such Fundamental Transaction,
(ii) an amount of cash (or other consideration) equal to the Black Scholes Value of the remaining unexercised portion of this Warrant
on the date of the consummation of the Fundamental Transaction, or (iii) the assumption by the Successor Entity of all of the obligations
of the Company under this Warrant and the option to receive a security of the Successor Entity evidenced by a written instrument
substantially similar in form and substance to this Warrant.</P>

Company of the proceeds from the sale of the Securities hereunder, (i) the fair saleable value of the Company&rsquo;s assets exceeds
the amount that will be required to be paid on or in respect of the Company&rsquo;s existing debts and other liabilities (including
known contingent liabilities) as they mature, (ii) the Company&rsquo;s assets do not constitute unreasonably small capital to carry
on its business as now conducted and as proposed to be conducted including its capital needs taking into account the particular
capital requirements of the business conducted by the Company, consolidated and projected capital requirements and capital availability
thereof, and (iii) the current cash flow of the Company, together with the proceeds the Company would receive, were it to liquidate
all of its assets, after taking into account all anticipated uses of the cash, would be sufficient to pay all amounts on or in
respect of its liabilities when such amounts are required to be paid. The Company does not intend to incur debts beyond its ability
to pay such debts as they mature (taking into account the timing and amounts of cash to be payable on or in respect of its debt).
The Company has no knowledge of any facts or circumstances which lead it to believe that it will file for reorganization or liquidation
under the bankruptcy or reorganization laws of any jurisdiction within one year from the Closing Date. <U>Schedule 3.1(aa)</U>
sets forth as of the date hereof all outstanding secured and unsecured Indebtedness of the Company or any Subsidiary, or for which
the Company or any Subsidiary has commitments. For the purposes of this Agreement, &ldquo;<U>Indebtedness</U>&rdquo; means (x)
any liabilities for borrowed money or amounts owed in excess of $50,000 (other than trade accounts payable incurred in the ordinary
course of business), (y) all guaranties, endorsements and other contingent obligations in respect of indebtedness of others, whether
or not the same are or should be reflected in the Company&rsquo;s consolidated balance sheet (or the notes thereto), except guaranties
by endorsement of negotiable instruments for deposit or collection or similar transactions in the ordinary course of business;
and (z) the present value of any lease payments in excess of $50,000 due under leases required to be capitalized in accordance
with GAAP. Neither the Company nor any Subsidiary is in default with respect to any Indebtedness.</P>

pursuant to the initial press release as described in Section 4.4, (ii) no Purchaser shall be restricted or prohibited from effecting
any transactions in any securities of the Company in accordance with applicable securities laws from and after the time that the
transactions contemplated by this Agreement are first publicly announced pursuant to the initial press release as described in
Section 4.4 and (iii) no Purchaser shall have any duty of confidentiality or duty not to trade in the securities of the Company
to the Company or its Subsidiaries after the issuance of the initial press release as described in Section 4.4.&nbsp; </FONT>Notwithstanding
the foregoing, in the case of a Purchaser that is a multi-managed investment vehicle whereby separate portfolio managers manage
separate portions of such Purchaser&rsquo;s assets and the portfolio managers have no direct knowledge of the investment decisions
made by the portfolio managers managing other portions of such Purchaser&rsquo;s assets, the covenant set forth above shall only
apply with respect to the portion of assets managed by the portfolio manager that made the investment decision to purchase the
Securities covered by this Agreement.</P>

below, the Company performed additional procedures during the third quarter and additional analysis and procedures post-closing
to ensure the Company&rsquo;s financial statements were prepared in accordance with generally accepted accounting principles. Accordingly,
the Company believes that the financial statements included in the Form 10-Q quarterly report for the quarter ended September 30,
2017 fairly present, in all material respects, the Company&rsquo;s financial condition, results of operations and cash flows for
the periods presented.</P>

<P STYLE="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0; text-indent: 0.5in; text-align: justify">A material weakness is a control deficiency
(within the meaning of the Public Company Accounting Oversight Board Auditing Standard 1305) or combination of control deficiencies
that result in more than a remote likelihood that a material misstatement of the annual or interim financial statements will not
be prevented or detected. During the last quarter of fiscal 2016, and as the Company&rsquo;s operational activities increased,
management determined that it did not have sufficient segregation of duties within its accounting functions, which is a basic internal
control. Due to the Company&rsquo;s size and nature, segregation of all conflicting duties may not always be possible and may not
be economically feasible. However, to the extent possible, the initiation of transactions, the custody of assets and the recording
of transactions should be performed by separate individuals. Management evaluated the impact of the Company&rsquo;s failure to
maintain effective segregation of duties on its assessment of its internal control over financial reporting and concluded that
the control deficiency represents a material weakness. Management added a full-time controller during the quarter ended September
30, 2017 and intends to further increase its accounting staff, as soon as economically feasible and sustainable, to remediate this
material weakness.</P>
