common stock of the Company, (ii) three series of warrants to purchase common stock, and (iii) the shares of common stock underlying
such warrants. This Post-Effective amendment updates the prospectus dated February 9, 2017. All applicable registration fees were

Capital Market under the symbol “MBRX.” On October 12, 2017, the last sale price for our common stock as reported on
the NASDAQ Capital Market was $2.28 per share. There is no established public trading market for the warrants, and we do not expect
a market to develop. In addition, we do not intend to apply for a listing of the warrants on any national securities exchange.
We are an “emerging growth company”
as defined in Section 2(a) of the Securities Act of 1933, as amended, and we have elected to comply with certain reduced public
company reporting requirements.

Overview
We are a clinical stage pharmaceutical company
organized as a Delaware corporation in July 2015 to focus on the development of anti-cancer drug candidates, some of which are
based on license agreements with The University of Texas System on behalf of the M.D. Anderson Cancer Center, which we refer to
as MD Anderson. Our lead drug candidate is liposomal Annamycin, which we refer to as Annamycin, an anthracycline being studied
for the treatment of relapsed or refractory acute myeloid leukemia, or AML. We have two other drug development projects in process,
one involving a collection of small molecules, which we refer to as the WP1066 Portfolio, focused on the modulation of key regulatory
transcription factors involved in the progression of cancer, and the WP1222 Portfolio, a suite of molecules targeting the metabolic
processes involved in cancer in general and glioblastoma (the most common form of brain tumor) in particular. We also continue
to sponsor ongoing research at MD Anderson in order to improve and expand our drug development pipeline.

Risk Factors
|
See “Risk Factors” and other information incorporated by reference into this prospectus for a discussion of factors you should carefully consider before deciding whether to invest in our common stock.
|
RISK FACTORS
Investing in shares of our common stock
involves a high degree of risk. Before making an investment decision, you should carefully consider the risks described below,
together with the risks described in the “Risk Factors” section in our most recent Annual Report on Form 10-K, as well
as any updates to those risk factors in our subsequent Quarterly Reports on Form 10-Q, together with all of the other information
appearing in or incorporated by reference into this prospectus, before deciding whether to purchase any of the common stock being
offered. The risks described in these documents are not the only ones we face, but those that we consider to be material. There
may be other unknown or unpredictable economic, business, competitive, regulatory or other factors that could have material adverse
effects on our future results. Our business, financial condition or results of operations could be materially adversely affected
by any of these risks. The trading price of shares of our common stock could decline due to any of these risks, and you may lose
all or part of your investment. Please also read carefully the section entitled “Cautionary Note Regarding Forward-Looking
Statements.”
Investors receiving shares of common stock upon exercise
of the warrants will incur immediate and substantial dilution.
Investors receiving shares of common stock
upon exercise of the warrants will incur immediate and substantial dilution in net tangible book value per share. As the exercise
prices for the Series A warrants and the Representative’s Warrant are $1.50 per share and $1.35 per share, respectively,
investors receiving shares of common stock upon exercise of the Series A warrants and the Representative’s Warrant will incur
dilution of $1.08 per share and $0.93 per share, respectively, in the net tangible book value of their purchased shares of our
common stock, assuming full exercise of such warrants. Investors may experience further dilution to the extent that shares of our
common stock are issued upon the exercise of outstanding stock options and warrants.

CAUTIONARY NOTE REGARDING FORWARD-LOOKING
STATEMENTS
Some of the information in this prospectus,
and the documents we incorporate by reference, contain forward-looking statements within the meaning of the federal securities
laws. You should not rely on forward-looking statements in this prospectus, and the documents we incorporate by reference. Forward-looking
statements typically are identified by use of terms such as “anticipate,” “believe,” “plan,”
“expect,” “future,” “intend,” “may,” “will,” “should,”
“estimate,” “predict,” “potential,” “continue,” and similar words, although some
forward-looking statements are expressed differently. This prospectus, and the documents we incorporate by reference, may also
contain forward-looking statements attributed to third parties relating to their estimates regarding the markets we may enter in
the future. All forward-looking statements address matters that involve risk and uncertainties, and there are many important risks,
uncertainties and other factors that could cause our actual results to differ materially from the forward-looking statements contained
in this prospectus, and the documents we incorporate by reference.
You should also consider carefully the statements
under “Risk Factors” and other sections of this prospectus, and the documents we incorporate by reference, which address
additional facts that could cause our actual results to differ from those set forth in the forward-looking statements. We caution
investors not to place significant reliance on the forward-looking statements contained in this prospectus, and the documents we
incorporate by reference. We undertake no obligation to publicly update or review any forward-looking statements, whether as a
result of new information, future developments or otherwise.
USE OF PROCEEDS
Assuming full exercise of the warrants,
we will receive gross proceeds of approximately $632,000. We currently intend to use such proceeds for working capital and general
corporate purposes. The amounts and timing of our use of the net proceeds from this offering will depend on a number of factors,
such as the timing and progress of our research and development efforts, the timing and progress of any partnering and commercialization
efforts, and technological advances. As of the date of this prospectus, we cannot specify with certainty all of the particular
uses for the net proceeds to us from this offering. Accordingly, our management will have broad discretion in the timing and application
of these proceeds.
DIVIDEND POLICY
We have never declared or paid any cash
dividends on our capital stock. We currently intend to retain earnings, if any, to finance the growth and development of our business.
We do not expect to pay any cash dividends on our common stock in the foreseeable future. Payment of future dividends, if any,
will be at the discretion of our board of directors and will depend on our financial condition, results of operations, capital
requirements, restrictions contained in any financing instruments, provisions of applicable law and other factors the board deems
relevant.
DILUTION
Upon exercise of the Series A warrants
and the Representative’s Warrant, a warrant holder’s ownership interest in our common stock will be diluted immediately
to the extent of the difference between the exercise price per warrant and the pro forma net tangible book value per share of our
common stock at the time of exercise of such warrant.
We calculate net tangible book value per
share by dividing the net tangible book value, which is tangible assets less total liabilities, by the number of outstanding shares
of our common stock. Dilution represents the difference between the portion of the amount per share paid by purchasers of shares
in this offering and the as adjusted net tangible book value per share of our common stock immediately after giving effect to this
offering. Our net tangible book value as of June 30, 2017 was approximately $8.1 million, or $0.40 per share.
After giving effect to the exercise of all
the Series A warrants and the Representative’s Warrant, our pro forma net tangible book value as of June 30, 2017 would have
been $8.8 million, or $0.42 per share. This represents an immediate increase in pro forma net tangible book value per share of
$0.02 to existing stockholders and immediate dilution of $1.08 and $0.93 in pro forma net tangible book value per share to new
investors receiving shares of common stock following exercise of the Series A warrants and the Representative’s Warrant,
respectively. Dilution per share to new investors is determined by subtracting pro forma net tangible book value per share after
this offering from the exercise price per warrant paid by new investors. The following table illustrates this dilution on a per
share basis:

The above table and discussion is based
on 20,164,854 shares of common stock outstanding as of June 30, 2017 and exclude the following, all as of June 30, 2017:
•
530,000
shares of common stock issuable upon the exercise of outstanding stock options, vested and unvested, with a weighted-average exercise
price of $5.17 per share;
• 948,011 shares
of common stock issuable upon the exercise of outstanding Series A, vested Series C and underwriter warrants from our February
14, 2017 follow-on offering with a weighted-average exercise price of $1.46 per share;
• 107,802 shares
of common stock issuable upon the exercise of outstanding underwriter warrants issued on May 1, 2016 related to our IPO with an
exercise price of $7.50 per share; and
• up to an
aggregate of 1,470,000 shares of common stock reserved for future issuance under our 2015 Stock Plan.
To the extent that
options or warrants outstanding as of June 30, 2017 have been or are exercised, or other shares are issued, investors purchasing
shares in this offering could experience further dilution. In addition, we may choose to raise additional capital due to market
conditions or strategic considerations, even if we believe we have sufficient funds for our current or future operating plans.
To the extent that additional capital is raised through the sale of equity or convertible debt securities, the issuance of these
securities could result in further dilution to our stockholders.
PLAN OF DISTRIBUTION
We are offering shares
of common stock issuable upon the exercise of outstanding Series A Warrants and of the Representative’s Warrant, respectively,
all of which were previously issued in connection with the February 2017 registered offering of our securities. The common stock
issuable upon the exercise of such warrants will not be offered through underwriters, or brokers or dealers. We will not pay any
compensation in connection with the offering of the shares upon exercise of the warrants.
DESCRIPTION OF CAPITAL STOCK
The following summary is a description
of the material terms of our capital stock and is not complete. You should also refer to the Moleculin Biotech, Inc. certificate
of incorporation and bylaws, which are included as exhibits to the registration statement of which this prospectus forms a part,
and the applicable provisions of the Delaware General Corporation Law.
Our amended and restated certificate of
incorporation authorizes us to issue up to 75,000,000 shares of common stock, par value $0.001 per share, and 5,000,000 shares
of preferred stock, $0.001 par value per share.
Common Stock
Shares of our common stock have the following
rights, preferences and privileges:
Voting
Each holder of common stock is entitled
to one vote for each share of common stock held on all matters submitted to a vote of stockholders. Any action at a meeting at
which a quorum is present will be decided by a majority of the voting power present in person or represented by proxy, except in
the case of any election of directors, which will be decided by a plurality of votes cast. There is no cumulative voting.
Dividends
Holders of our common stock are entitled
to receive dividends when, as and if declared by the our board of directors out of funds legally available for payment, subject
to the rights of holders, if any, of any class of stock having preference over the common stock. Any decision to pay dividends
on our common stock will be at the discretion of our board of directors. Our board of directors may or may not determine to declare
dividends in the future. See “Dividend Policy.” The board’s determination to issue dividends will depend upon
our profitability and financial condition any contractual restrictions, restrictions imposed by applicable law and the SEC, and
other factors that our board of directors deems relevant.
Liquidation Rights
In the event of a voluntary or involuntary
liquidation, dissolution or winding up of the company, the holders of our common stock will be entitled to share ratably on the
basis of the number of shares held in any of the assets available for distribution after we have paid in full, or provided for
payment of, all of our debts and after the holders of all outstanding series of any class of stock have preference over the common
stock, if any, have received their liquidation preferences in full.
Other
Our issued and outstanding shares of common
stock are fully paid and nonassessable. Holders of shares of our common stock are not entitled to preemptive rights. Shares of
our common stock are not convertible into shares of any other class of capital stock, nor are they subject to any redemption
or sinking fund provisions.
Preferred Stock
We are authorized to issue up to 5,000,000 shares
of preferred stock. Our certificate of incorporation authorizes the board to issue these shares in one or more series, to determine
the designations and the powers, preferences and relative, participating, optional or other special rights and the qualifications,
limitations and restrictions thereof, including the dividend rights, conversion or exchange rights, voting rights (including the
number of votes per share), redemption rights and terms, liquidation preferences, sinking fund provisions and the number of shares
constituting the series. Our board of directors could, without stockholder approval, issue preferred stock with voting and other
rights that could adversely affect the voting power and other rights of the holders of common stock and which could have the effect
of making it more difficult for a third party to acquire, or of discouraging a third party from attempting to acquire, a majority
of our outstanding voting stock.
Series A Warrants
The following summary of certain terms
and provisions of the Series A warrants is not complete and is subject to, and qualified in its entirety by, the provisions of
the warrant, the form of which is filed as an exhibit to the registration statement of which this prospectus forms a part.
Duration and Exercise Price
. The
Series A warrant has an exercise price of $1.50 per share. The Series A warrants are immediately exercisable and expire on February
14, 2022. The exercise price and number of shares of common stock issuable upon exercise is subject to appropriate adjustment in
the event of stock dividends, stock splits, reorganizations or similar events affecting our common stock.
Exercisability
. The Series A warrants
will be exercisable, at the option of each holder, in whole or in part, by delivering to us a duly executed exercise notice accompanied
by payment in full for the number of shares of our common stock purchased upon such exercise (except in the case of a cashless
exercise as discussed below). A holder (together with its affiliates) may not exercise any portion of the warrant to the extent
that the holder would own more than 4.99% (or, at the election of the holder, 9.99%) of the outstanding common stock immediately
after exercise, provided that the holder may increase the limitation on amount of ownership of outstanding stock after exercising
the holder’s warrants up to 9.99% of the number of shares of our common stock outstanding immediately after giving effect
to the exercise, as such percentage ownership is determined in accordance with the terms of the warrants, provided further that
any increase in such limitation shall not be effective until 61 days following notice from the holder to us. No fractional shares
of common stock will be issued in connection with the exercise of a warrant. In lieu of fractional shares, we will either pay the
holder an amount in cash equal to the fractional amount multiplied by the exercise price or round up to the next whole share.
Cashless Exercise
. If, at the time
a holder exercises its warrant, a registration statement registering the issuance of the shares of common stock underlying the
Series A warrants under the Securities Act is not then effective or available, then in lieu of making the cash payment otherwise
contemplated to be made to us upon such exercise in payment of the aggregate exercise price, if the holder chooses to exercise
the warrants it must elect instead to receive upon such exercise (either in whole or in part) the net number of shares of common
stock determined according to a formula set forth in the warrant.
Fundamental Transactions
. If a fundamental
transaction occurs, then the successor entity will succeed to, and be substituted for us, and may exercise every right and power
that we may exercise and will assume all of our obligations under the warrants with the same effect as if such successor entity
had been named in the warrant itself. If holders of our common stock are given a 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 consideration it receives
upon any exercise of the warrant following such fundamental transaction. In addition, in the event of a fundamental transaction,
at the request of the holder, we or the successor entity shall purchase the unexercised portion of the warrant from the holder
by paying to the holder cash in an amount equal to the Black-Scholes value (as defined in the warrants) of the remaining unexercised
portion of the warrant on the date of such fundamental transaction.
Exchange Listing
. We do not intend
to list the warrants on any securities exchange or nationally recognized trading system.
Right as a Stockholder
. Except as
otherwise provided in the warrants or by virtue of such holder’s ownership of shares of our common stock, the holders of
the warrants do not have the rights or privileges of holders of our common stock, including any voting rights, until they exercise
their warrants.
Representative’s Warrant
The Representative’s Warrant is materially
similar to the Series A warrants discussed above, except that the exercise price is $1.35 per share.
Listing
Our common stock is listed on the Nasdaq
Capital Market under the symbol “MBRX”.
Transfer Agent
The transfer agent for our common stock
is VStock Transfer, LLC.

fees), judgments, fines and amounts paid in settlement actually and reasonably incurred in connection with such action, suit or
proceeding, if such person acted in good faith and in a manner he or she reasonably believed to be in or not opposed to the best
interests of such corporation, and, with respect to any criminal action or proceeding, had no reasonable cause to believe his or
her conduct was unlawful.
The DGCL also permits indemnification by
a corporation under similar circumstances for expenses (including attorneys’ fees) actually and reasonably incurred by such
persons in connection with the defense or settlement of a derivative action or suit, except that no indemnification shall be made
in respect of any claim, issue or matter as to which such person shall have been adjudged to be liable to such corporation unless
the Delaware Court of Chancery or the court in which such action or suit was brought shall determine upon application that such
person is fairly and reasonably entitled to indemnity for such expenses which such court shall deem proper.
To the extent a present or former director
or officer is successful in the defense of such an action, suit or proceeding referenced above, or in defense of any claim, issue
or matter therein, a corporation is required by the DGCL to indemnify such person for actual and reasonable expenses incurred in
connection therewith. Expenses (including attorneys’ fees) incurred by such persons in defending any action, suit or proceeding
may be paid in advance of the final disposition of such action, suit or proceeding upon in the case of a current officer or director,
receipt of an undertaking by or on behalf of such person to repay such amount if it is ultimately determined that such person is
not entitled to be so indemnified.
The DGCL provides that the indemnification
described above shall not be deemed exclusive of other indemnification that may be granted by a corporation pursuant to its bylaws,
disinterested directors’ vote, stockholders’ vote and agreement or otherwise.
Section 102(b)(7) of the DGCL enables
a corporation, in its certificate of incorporation or an amendment thereto, to eliminate or limit the personal liability of a director
to the corporation or its stockholders for monetary damages for violations of the directors’ fiduciary duty, except (i) for
any breach of the director’s duty of loyalty to the corporation or its stockholders, (ii) for acts or omissions not
in good faith or which involve intentional misconduct or a knowing violation of law, (iii) pursuant to Section 174 of
the DGCL (providing for liability of directors for unlawful payment of dividends or unlawful stock purchases or redemptions) or
(iv) for any transaction from which a director derived an improper personal benefit. The Registrant’s certificate of
incorporation provides for such limitations on liability for its directors.
The DGCL also provides corporations with
the power to purchase and maintain insurance on behalf of any person who is or was a director, officer, employee or agent of such
corporation, or is or was serving at the request of such corporation in a similar capacity for another corporation, partnership,
joint venture, trust or other enterprise, against any liability asserted against him or her in any such capacity or arising out
of his or her status as such, whether or not the corporation would have the power to indemnify him or her against such liability
as described above. In connection with this offering, the Registrant will obtain liability insurance for its directors and officers.
Such insurance would be available to its directors and officers in accordance with its terms.
The Registrant’s certificate of incorporation
in requires the Registrant to indemnify and hold harmless, to the fullest extent permitted by applicable law as it presently exists
or may hereafter be amended, any person (a “covered person”) who was or is made or is threatened to be made a party
or is otherwise involved in any threatened, pending or completed action, suit or proceeding, whether civil, criminal, administrative
or investigative (a “proceeding”) by reason of the fact that he or she is or was a director, officer or member of a
committee of the Registrant, or, while a director or officer of the Registrant, is or was serving at the request of the Registrant
as a director or officer, employee or agent of another corporation, partnership, joint venture, trust or other enterprise or non-profit
entity, including service with respect to employee benefit plans, against all liability and loss suffered and expenses (including
attorneys’ fees), judgment, fines and amounts paid in settlement actually and reasonably incurred by such person in connection
with a proceeding.
In addition, under the Registrant’s
certificate of incorporation, in certain circumstances, the Registrant shall pay the expenses (including attorneys’ fees)
incurred by a covered person in defending a proceeding in advance of the final disposition of such proceeding; provided, however,
that the Registrant shall not be required to advance any expenses to a person against whom the Registrant directly brings an action,
suit or proceeding alleging that such person (1) committed an act or omission not in good faith or (2) committed an act
of intentional misconduct or a knowing violation of law. Additionally, an advancement of expenses incurred by a covered person
shall be made only upon delivery to the Registrant of an undertaking, by or on behalf of such covered person, to repay all amounts
so advanced if it shall ultimately be determined by final judicial decision from which there is no further right to appeal or otherwise
in accordance with Delaware law that such covered person is not entitled to be indemnified for such expenses.
The foregoing statements are subject to
the detailed provisions of Section 145 of the DGCL and the full text of the Registrant’s certificate of incorporation,
which is filed as Exhibit 3.1 hereto.
Item 15. Recent Sales of Unregistered Securities.
Except as set forth below, in the three
years preceding the filing of this Registration Statement, the Registrant has not issued any securities that were not registered
under the Securities Act:
In August 2015, Messrs. Klemp, Picker and
Priebe purchased 1,100,000 shares, 500,000 shares and 3,000,000 shares of our common stock, respectively, at a purchase price of
$0.001 per share.
In August 2015, in exchange for the issuance
of 630,000 shares of common stock, we acquired the rights to the license agreement with MD Anderson covering our WP1122 Portfolio
held by IntertechBio Corporation, a company affiliated with Messrs. Priebe and Picker. In August 2015, in exchange for the issuance
of 1,431,000 shares of common stock, we acquired the rights to the Annamycin IND and all data related to the Annamycin IND or the
development of Annamycin held by AnnaMed, Inc., a company affiliated with Mr. Klemp.
In May 2016, Moleculin, LLC, a Texas limited
liability company, was merged with and into MBI, which survived the merger. As a result of the merger, we issued the equity interests
holders of Moleculin, LLC (including the convertible noteholders of Moleculin, LLC) an aggregate of 999,931 shares of our common
stock. Messrs. Klemp, Picker and Priebe are members of Moleculin, LLC and received shares of our common stock as a result of the
merger.
In August and September 2015, the Registrant
issued two 8% convertible notes in an aggregate of $250,000 in principal amount of convertible notes to one investor, which principal
and accrued interest automatically converted into shares of common stock upon the closing of the Company’s initial public
offering at a conversion rate of $0.1299 per share. In October 2015, the Registrant issued two 8% convertible notes in an aggregate
of $200,000 in principal amount of convertible notes to two investors, which principal and accrued interest automatically converted
into shares of common stock upon the closing of the Company’s initial public offering at a conversion rate of $0.20 per share.
At the time of such purchase in October 2015, the convertible note investors and the Registrant agreed that the investors would
fund the Registrant up to the filing of its initial non-confidential registration statement an additional $165,000 on the same
terms as in the October financing. Pursuant to such agreement, such amounts were received in January 2016.
Between January and May 2016, the Registrant
sold 225,963 shares of common stock for a total purchase price of $677,889 to 19 investors.
On June 20, 2016, the Registrant agreed
to issue 24,000 shares of common stock to an investor relations firm for services provided.
In January 2017, the Registrant agreed to
issue 79,167 shares of common stock to a third-party in settlement of $237,500 in past due amounts.
In July 2017, the Registrant agreed to issue
two warrants to purchase 100,000 and 50,000 shares of common stock at exercise prices of $2.41 and $3.00 per share, respectively,
to a consultant, subject to approval by Nasdaq of a listing of additional shares application, which was received in August 2017.
None of these transactions involved
a public offering. We believe that each of the above issuances was exempt from registration under the Securities Act in reliance
on Section 4(a)(2) of the Securities Act regarding transactions not involving a public offering.
Item 16. Exhibits and Financial Statement Schedules.
(a)
Exhibits
: Reference is
made to the Exhibit Index following the signature pages hereto, which Exhibit Index is hereby incorporated into this Item.
(b)
Financial Statement Schedules
:
All schedules are omitted because the required information is inapplicable or the information is presented in the financial statements
and the related notes.
Item 17. Undertakings
(a) The
undersigned Registrant hereby undertakes:
(1) To file, during any period in
which offers or sales are being made, a post-effective amendment to this registration statement:
(i) To include any prospectus required
by Section 10(a)(3) of the Securities Act of 1933;
(ii) To reflect in the prospectus
any facts or events arising after the effective date of the registration statement (or the most recent post-effective amendment
thereof) which, individually or in the aggregate, represent a fundamental change in the information set forth in the registration
statement. Notwithstanding the foregoing, any increase or decrease in volume of securities offered (if the total dollar value of
securities offered would not exceed that which was registered) and any deviation from the low or high end of the estimated maximum
offering range may be reflected in the form of prospectus filed with the Commission pursuant to Rule 424(b) if, in the aggregate,
the changes in volume and price represent no more than a 20% change in the maximum aggregate offering price set forth in the “Calculation
of Registration Fee” table in the effective registration statement.
(iii) To include any material information
with respect to the plan of distribution not previously disclosed in the registration statement or any material change to such
information in the registration statement;
Provided, however, that Paragraphs (a)(1)(i),
(a)(1)(ii) and (a)(1)(iii) of this section do not apply if the registration statement is on Form S-1 and the information required
to be included in a post-effective amendment by those paragraphs is contained in reports filed with or furnished to the Commission
by the Registrant pursuant to Section 13 or Section 15(d) of the Securities Exchange Act of 1934 that are incorporated by reference
in the registration statement.
(2) That, for the purpose of determining
any liability under the Securities Act of 1933, each such post-effective amendment shall be deemed to be a new registration statement
relating to the securities offered therein, and the offering of such securities at that time shall be deemed to be the initial
bona fide offering thereof.
(3) To remove from registration by
means of a post-effective amendment any of the securities being registered which remain unsold at the termination of the offering.
(b) Insofar as indemnification for liabilities
arising under the Securities Act of 1933 may be permitted to directors, officers and controlling persons of the registrant pursuant
to the provisions referenced in Item 14 of this Registration Statement, or otherwise, the Registrant has been advised that
in the opinion of the Securities and Exchange Commission such indemnification is against public policy as expressed in the Act
and is, therefore, unenforceable. In the event that a claim for indemnification against such liabilities (other than the payment
by the registrant of expenses incurred or paid by a director, officer, or controlling person of the registrant in the successful
defense of any action, suit or proceeding) is asserted by such director, officer or controlling person in connection with the securities
being registered hereunder, the registrant will, unless in the opinion of its counsel the matter has been settled by controlling
precedent, submit to a court of appropriate jurisdiction the question of whether such indemnification by it is against public policy
as expressed in the Act and will be governed by the final adjudication of such issue.
(c) The undersigned Registrant hereby undertakes
that each prospectus filed pursuant to Rule 424(b) as part of a registration statement relating to an offering, other than registration
statements relying on Rule 430B or other than prospectuses filed in reliance on Rule 430A, shall be deemed to be part of and included
in the registration statement as of the date it is first used after effectiveness. Provided, however, that no statement made in
a registration statement or prospectus that is part of the registration statement or made in a document incorporated or deemed
incorporated by reference into the registration statement or prospectus that is part of the registration statement will, as to
a purchaser with a time of contract of sale prior to such first use, supersede or modify any statement that was made in the registration
statement or prospectus that was part of the registration statement or made in any such document immediately prior to such date
of first use.
(d) That, for purposes of determining any
liability under the Securities Act of 1933, each filing of the registrant’s annual report pursuant to section 13(a) or section
15(d) of the Securities Exchange Act of 1934 (and, where applicable, each filing of an employee benefit plan’s annual report
pursuant to section 15(d) of the Securities Exchange Act of 1934) that is incorporated by reference in the registration statement
shall be deemed to be a new registration statement relating to the securities offered therein, and the offering of such securities
at that time shall be deemed to be the initial bona fide offering thereof.
SIGNATURES
Pursuant to the requirements of the Securities
Act, the registrant has duly caused this Registration Statement to be signed on its behalf by the undersigned, thereunto duly authorized,
