1.         Purchase
Warrant. THIS CERTIFIES THAT, pursuant to that certain Underwriting Agreement by and between LIPELLA PHARMACEUTICALS INC.,
a Delaware corporation (the “Company”), on one hand, and Spartan Capital Securities, LLC (the “Holder”),
on the other hand, dated [●] (the “Underwriting Agreement”), the Holder, as registered owner of this underwriter’s
warrant (this “Purchase Warrant”), is entitled, at any time or from time to time from [●] (the “Exercise
Date”), and at or before 5:00 p.m., Eastern Time, on [●] (the “Expiration Date”), but not thereafter,
to subscribe for, purchase and receive, in whole or in part, up to [●] shares of Common Stock of the Company, par value $0.0001
per share (“Common Stock”) (the “Shares”), subject to adjustment as provided in Section
6 hereof. If the Expiration Date is a day on which banking institutions are authorized by law to close, then this Purchase
Warrant may be exercised on the next succeeding day which is not such a day in accordance with the terms herein. During the period
ending on the Expiration Date, the Company agrees not to take any action that would terminate this Purchase Warrant. This Purchase
Warrant is initially exercisable at $[●] per share (125% of the price of the shares of Common Stock sold in the Offering);
provided, however, that upon the occurrence of any of the events specified in Section 6 hereof, the rights granted
by this Purchase Warrant, including the exercise price per share and the number of shares of Common Stock to be received upon such
exercise, shall be adjusted as therein specified. The term “Exercise Price” shall mean the initial exercise
price of this Purchase Warrant as set forth above or the adjusted exercise price as a result of the events set forth in Section
6 below, depending on the context. Capitalized terms not defined herein shall have the meaning ascribed to them in the Underwriting
Agreement.







 


2.         Exercise.


 


2.1       Exercise
Form. In order to exercise this Purchase Warrant, the exercise form attached hereto as Exhibit A must be duly executed
and completed and delivered to the Company, together with this Purchase Warrant and payment of the Exercise Price for the shares
of Common Stock being purchased payable in cash by wire transfer of immediately available funds to an account designated by the

hereby shall cease and expire.


 



    1



     


    

 


2.2       Cashless
Exercise. The Holder may elect to receive the number of shares of Common Stock equal to the value of this Purchase Warrant
(or the portion thereof being exercised), by surrender of this Purchase Warrant to the Company, together with the exercise form
attached hereto, in which event the Company shall issue to Holder, Shares in accordance with the following formula:


 


	X	=	Y(A-B)	 	 
	A	 	 
	 	 	 	 
	Where,	X	=	The number of shares
    of Common Stock to be issued to Holder;
	 	Y	=	The number of shares
    of Common Stock for which the Purchase Warrant is being exercised;
	 	A	=	The fair market
    value of one share of Common Stock; and
	 	B	=	The Exercise Price.


 


For
purposes of this Section 2.2, the “fair market value” of a share of Common Stock is defined as follows:


 


	 	(i)	if the shares of
    Common Stock are traded on a national securities exchange, the value shall be deemed to be the weighted average closing price
    on such exchange for the five consecutive trading days ending on the trading day immediately prior to the exercise form being
    submitted in connection with the exercise of the Purchase Warrant; or



 

	 	(ii)	if the shares of
    Common Stock are actively traded over-the-counter, the value shall be deemed to be the weighted average closing bid price
    of the shares of Common Stock for the five consecutive trading days ending on the trading day immediately prior to the exercise
    form being submitted in connection with the exercise of the Purchase Warrant; or


 


	 	(iii)	if there is no market
    for the shares of Common Stock, the value shall be the fair market value thereof, as determined in good faith by the Board.


 


2.3             Legend.
Each certificate for the securities purchased under this Purchase Warrant shall bear the following legends unless such securities
have been registered under the Securities Act of 1933, as amended (the “Act”), or are exempt from registration

INCLUDING, THE DATE THAT IS ONE HUNDRED AND EIGHTY (180) DAYS BEGINNING ON THE DATE OF COMMENCEMENT OF SALES OF THE OFFERING PURSUANT

case in accordance with FINRA Rule 5110(e)(2)(B), or (b) cause this Purchase Warrant or the securities issuable hereunder to be

6.1         Adjustments
to Exercise Price and Number of Shares of Common Stock. The Exercise Price and the number of Shares of Common Stock underlying
this Purchase Warrant shall be subject to adjustment from time to time as hereinafter set forth:


 


6.1.1       Share
Dividends; Split Ups. If, after the date hereof, and subject to the provisions of Section 6.3 below, the number of
outstanding shares of Common Stock is increased by a stock dividend payable in shares of Common Stock or by a split up of shares
of Common Stock or other similar event, then, on the effective day thereof, the number of shares of Common Stock purchasable hereunder
shall be increased in proportion to such increase in outstanding shares of Common Stock , and the Exercise Price shall be proportionately
decreased.


 






    3



     


    

 


6.1.2       Aggregation
of Shares of Common Stock. If, after the date hereof, and subject to the provisions of Section 6.3 below, the number
of outstanding shares of Common Stock is decreased by a consolidation, combination or reclassification of shares of Common Stock
or other similar event, then, on the effective date thereof, the number of shares of Common Stock purchasable hereunder shall
be decreased in proportion to such decrease in outstanding shares, and the Exercise Price shall be proportionately increased.


 


6.1.3       Replacement
of shares of Common Stock upon Reorganization, etc. In case of any reclassification or reorganization of the outstanding shares
of Common Stock other than a change covered by Section 6.1.1 or Section 6.1.2 hereof or that solely affects the
par value of such shares of Common Stock, or in the case of any share reconstruction or amalgamation or consolidation of the Company
with or into another corporation (other than a consolidation or share reconstruction or amalgamation in which the Company is the
continuing corporation and that does not result in any reclassification or reorganization of the outstanding shares of Common
Stock ), or in the case of any sale or conveyance to another corporation or entity of the property of the Company as an entirety
or substantially as an entirety in connection with which the Company is dissolved, the Holder of this Purchase Warrant shall have
the right thereafter (until the expiration of the right of exercise of this Purchase Warrant) to receive upon the exercise hereof,
for the same aggregate Exercise Price payable hereunder immediately prior to such event, the kind and amount of shares of Common
Stock or other securities or property (including cash) receivable upon such reclassification, reorganization, share reconstruction
or amalgamation, or consolidation, or upon a dissolution following any such sale or transfer, by a Holder of the number of shares
of Common Stock of the Company obtainable upon exercise of this Purchase Warrant immediately prior to such event; and if any reclassification
also results in a change in shares of Common Stock covered by Section 6.1.1 or Section 6.1.2, then such adjustment
shall be made pursuant to Section 6.1.1, Section 6.1.2 and this Section 6.1.3. The provisions of this Section
6.1.3 shall similarly apply to successive reclassifications, reorganizations, share reconstructions or amalgamations, or consolidations,
sales or other transfers.


 


6.1.4       Fundamental
Transaction. If, at any time while this Purchase Warrant is outstanding, the Company enters into the following transactions
with another Person or group of Persons whereby such other Person or group acquires more than 50% of the outstanding shares of
Common Stock (not including any shares of Common Stock held by the other Person or other Persons making or party to, or associated
or affiliated with, the other Persons making or party to such stock or share purchase agreement or other business combination):
(i) the Company, directly or indirectly, in one or more related transactions effects any merger or consolidation of the Company
with or into another Person, (ii) the Company, directly or indirectly, effects any sale, lease, license, assignment, transfer,
conveyance or other disposition of all or substantially all of its assets in one or a series of related transactions, (iii) any
direct or indirect purchase offer, tender offer or exchange offer (whether by the Company or another Person) is completed pursuant
to which holders of shares of Common Stock are permitted to sell, tender or exchange their shares for other securities, cash or
property and has been accepted by the holders of 50% or more of the outstanding shares of Common Stock, (iv) the Company, directly
or indirectly, in one or more related transactions effects any reclassification, reorganization or recapitalization of the shares
of Common Stock or any compulsory share exchange pursuant to which the shares of Common Stock is effectively converted into or
exchanged for other securities, cash or property, or (v) the Company, directly or indirectly, in one or more related transactions
consummates a stock or share purchase agreement or other business combination (including, without limitation, a reorganization,
recapitalization, spinoff or scheme of arrangement) with another Person or group of Persons (each a “Fundamental Transaction”),
then, upon any subsequent exercise of this Purchase Warrant, the Holder shall have the right to receive, for each Share that would
have been issuable upon such exercise immediately prior to the occurrence of such Fundamental Transaction, 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
or alternative consideration (the “Alternative Consideration”) receivable as a result of such Fundamental Transaction
by a holder of the number of shares of Common Stock for which this Purchase Warrant is exercisable immediately prior to such Fundamental
Transaction. For purposes of any such exercise, the determination of the Exercise Price shall be appropriately adjusted to apply
to such Alternative Consideration based on the amount of Alternative Consideration issuable in respect of one share of Common
Stock in such Fundamental Transaction, and the Company shall apportion the Exercise Price among the Alternative Consideration
in a reasonable manner reflecting the relative value of any different components of the Alternative Consideration. If holders
of shares 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 Alternative Consideration it receives upon any exercise of this Purchase
Warrant following such Fundamental Transaction. The Company shall cause any successor entity in a Fundamental Transaction in which
the Company is not the survivor (the “Successor Entity”) to assume in writing all of the obligations of the
Company under this Purchase Warrant, and to deliver to the Holder in exchange for this Purchase Warrant a security of the Successor
Entity evidenced by a written instrument substantially similar in form and substance to this Purchase 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 Purchase Warrant immediately 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, the value of such shares of capital
stock, the number of shares of such capital stock and the exercise price for such shares of capital stock for the purpose of protecting
the economic value of this Purchase Warrant immediately prior to the consummation of such Fundamental Transaction). 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 Purchase Warrant referring to the “Company” 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 Purchase Warrant with the same effect as if such Successor Entity had been named as the Company herein.

6.1.5       Changes
in Form of Purchase Warrant. This form of Purchase Warrant need not be changed because of any change pursuant to this Section
6.1, and any warrants issued after such change, in exchange or replacement of this Purchase Warrant may state the same Exercise
Price and the same number of shares of Common Stock as are stated in the Purchase Warrant initially issued pursuant to this Purchase
Warrant. The acceptance by any Holder of the issuance of a new warrant reflecting a required or permissive change shall not be
deemed to waive any rights to an adjustment occurring after the date hereof or the computation thereof.


 


6.2         Substitute
Purchase Warrant. Except as otherwise provided in Section 6.1.5, in case of any consolidation of the Company with, or share
reconstruction or amalgamation of the Company with or into, another corporation (other than a consolidation or share reconstruction
or amalgamation which does not result in any reclassification or change of the outstanding shares of Common Stock ), the corporation
formed by such consolidation or share reconstruction or amalgamation shall execute and deliver to the Holder a supplemental warrant
providing that the holder of this Purchase Warrant shall have the right thereafter (until the stated expiration of this Purchase
Warrant) to receive, upon exercise of such supplemental warrant, the kind and amount of shares of common stock and other securities
and property receivable upon such consolidation or share reconstruction or amalgamation, by a holder of the number of shares of
Common Stock of the Company for which this Purchase Warrant might have been exercised immediately prior to such consolidation,
share reconstruction or amalgamation, sale or transfer. Such supplemental warrant shall provide for adjustments which shall be
substantially the same to the adjustments provided for in this Section 6. The above provisions of this Section 6
shall similarly apply to successive consolidations or share reconstructions or amalgamations.


 


6.3         Elimination
of Fractional Interests. The Company shall not be required to issue certificates representing fractions of shares of Common
Stock upon the exercise of this Purchase Warrant, nor shall it be required to issue scrip or pay cash in lieu of any fractional
interests, it being the intent of the parties that all fractional interests shall be eliminated by rounding any fraction up or
down, as the case may be, to the nearest whole number of shares of Common Stock or other securities, properties or rights.


 


7.         Reservation
and Listing. The Company shall at all times reserve and keep available out of its authorized shares of Common Stock, solely
for the purpose of issuance upon exercise of this Purchase Warrant, such number of shares of Common Stock or other securities,
properties or rights as shall be issuable upon the exercise thereof. The Company covenants and agrees that, upon exercise of this
Purchase Warrant and payment of the Exercise Price therefor, unless this Purchase Warrant is exercised pursuant to a cashless
exercise, as provided in Section 2.2 hereof, in accordance with the terms hereby, all shares of Common Stock and other
securities issuable upon such exercise shall be duly and validly issued, fully paid and non-assessable and not subject to preemptive
rights of any shareholder. The Company further covenants and agrees that upon exercise of this Purchase Warrant and payment of
the exercise price therefor, unless this Purchase Warrant is exercised pursuant to a cashless exercise, as provided in Section
2.2 hereof, all shares of Common Stock and other securities issuable upon such exercise shall be duly and validly issued,
fully paid and non-assessable and not subject to preemptive rights of any shareholder. As long as this Purchase Warrant shall
be outstanding, the Company shall use its commercially reasonable efforts to cause all shares of Common Stock issuable upon exercise
of this Purchase Warrant to be listed (subject to official notice of issuance) on all national securities exchanges (or, if applicable,
on the OTCQB Market or any successor quotation system) on which the shares of Common Stock are then listed and/or quoted (if at
all).

8.         Certain
Notice Requirements.


 


8.1         Holder’s
Right to Receive Notice. Nothing herein shall be construed as conferring upon the Holder the right to vote or consent or to
receive notice as a shareholder for the election of directors or any other matter, or as having any rights whatsoever as a shareholder
of the Company. If, however, at any time prior to the expiration of this Purchase Warrant and the exercise thereof, any of the
events described in Section 8.2 shall occur, then, in one or more of said events, the Company shall give written notice
of such event at least fifteen days prior to the date fixed as a record date or the date of closing the transfer books (the “Notice
Date”) for the determination of the shareholders entitled to such dividend, distribution, conversion or exchange of
securities or subscription rights, or entitled to vote on such proposed dissolution, liquidation, winding up or sale. Such notice
shall specify such record date or the date of the closing of the transfer books, as the case may be. Notwithstanding the foregoing,
the Company shall deliver to the Holder a copy of each notice given to the other shareholders of the Company at the same time
and in the same manner that such notice is given to the shareholders.


 


8.2         Events
Requiring Notice. The Company shall be required to give the notice described in this Section 8 upon one or more of
the following events: (i) if the Company shall take a record of the holders of its shares of Common Stock for the purpose of entitling

(ii) the Company shall offer to all the holders of its shares of Common Stock any additional shares of capital stock of the Company
or securities convertible into or exchangeable for shares of capital stock of the Company, or any option, right or warrant to
subscribe therefor, or (iii) a dissolution, liquidation or winding up of the Company (other than in connection with a consolidation
or share reconstruction or amalgamation) or a sale of all or substantially all of its property, assets and business shall be proposed.


 


8.3         Notice
of Change in Exercise Price. The Company shall, promptly after an event requiring a change in the Exercise Price pursuant
to Section 6 hereof, send notice to the Holder of such event and change (“Price Notice”). The Price

accurate by the Company’s Chief Financial Officer.

9.         Miscellaneous.


 


9.1         Amendments.
The Company and the Underwriter may from time to time supplement or amend this Purchase Warrant without the approval of the Holder
in order to cure any ambiguity, to correct or supplement any provision contained herein that may be defective or inconsistent
with any other provisions herein, or to make any other provisions in regard to matters or questions arising hereunder that the
Company and the Underwriter may deem necessary or desirable and that the Company and the Underwriter deem shall not adversely
affect the interest of the Holder. All other modifications or amendments shall require the written consent of and be signed by
the party against whom enforcement of the modification or amendment is sought.


 


9.2         Headings.
The headings contained herein are for the sole purpose of convenience of reference, and shall not in any way limit or affect the
meaning or interpretation of any of the terms or provisions of this Purchase Warrant.


 


9.3         Entire
Agreement. This Purchase Warrant (together with the other agreements and documents being delivered pursuant to or in connection
with this Purchase Warrant) constitutes the entire agreement of the parties hereto with respect to the subject matter hereof,
and supersedes all prior agreements and understandings of the parties, oral and written, with respect to the subject matter hereof.


 


9.4         Binding
Effect. This Purchase Warrant shall inure solely to the benefit of and shall be binding upon, the Holder and the Company and
their permitted assignees, respective successors, legal representative and assigns, and no other person shall have or be construed
to have any legal or equitable right, remedy or claim under or in respect of or by virtue of this Purchase Warrant or any provisions
herein contained.


 


9.5         Governing
Law; Submission to Jurisdiction; Trial by Jury. This Purchase Warrant shall be governed by and construed and enforced in accordance
with the laws of the State of New York, without giving effect to conflict of laws principles thereof. The Company hereby agrees
that any action, proceeding or claim against it arising out of, or relating in any way to this Purchase Warrant shall be brought
and enforced in the New York Supreme Court, County of New York, or in the United States District Court for the Southern District
of New York, and irrevocably submits to such jurisdiction, which jurisdiction shall be exclusive. The Company hereby waives any
objection to such exclusive jurisdiction and that such courts represent an inconvenient forum. Any process or summons to be served
upon the Company may be served by transmitting a copy thereof by registered or certified mail, return receipt requested, postage
prepaid, addressed to it at the address set forth in Section 8 hereof. Such mailing shall be deemed personal service and
shall be legal and binding upon the Company in any action, proceeding or claim. The Company and the Holder agree that the prevailing
party(ies) in any such action shall be entitled to recover from the other party(ies) all of its reasonable attorneys’ fees
and expenses relating to such action or proceeding and/or incurred in connection with the preparation therefor. The Company (on
its behalf and, to the extent permitted by applicable law, on behalf of its stockholders and affiliates) and the Holder hereby
irrevocably waive, to the fullest extent permitted by applicable law, any and all right to trial by jury in any legal proceeding
arising out of or relating to this Agreement or the transactions contemplated hereby.

9.6         Waiver,
etc. The failure of the Company or the Holder to at any time enforce any of the provisions of this Purchase Warrant shall
not be deemed or construed to be a waiver of any such provision, nor to in any way affect the validity of this Purchase Warrant
or any provision hereof or the right of the Company or any Holder to thereafter enforce each and every provision of this Purchase
Warrant. No waiver of any breach, non-compliance or non-fulfillment of any of the provisions of this Purchase Warrant shall be
effective unless set forth in a written instrument executed by the party or parties against whom or which enforcement of such
waiver is sought; and no waiver of any such breach, non-compliance or non-fulfillment shall be construed or deemed to be a waiver
of any other or subsequent breach, non-compliance or non-fulfillment.


 


9.7         Holder
Not Deemed a Shareholder. Except as otherwise specifically provided herein, the Holder, solely in its capacity as a holder
of this Purchase Warrant, shall not be entitled to vote or receive dividends or be deemed the holder of share capital of the Company
for any purpose, nor shall anything contained in this Purchase Warrant be construed to confer upon the Holder, solely in its capacity
as a holder of this Purchase Warrant, any of the rights of a shareholder of the Company or any right to vote, give or withhold
consent to any corporate action (whether any reorganization, issue of shares, reclassification of shares, consolidation, merger,
conveyance or otherwise), receive notice of meetings, receive dividends or subscription rights, or otherwise, prior to the issuance
to the Holder of the Shares which it is then entitled to receive upon the due exercise of this Purchase Warrant. In addition,
nothing contained in this Purchase Warrant shall be construed as imposing any liabilities on the Holder to purchase any securities
(upon exercise of this Purchase Warrant or otherwise) or as a shareholder of the Company, whether such liabilities are asserted
by the Company or by creditors of the Company.


 


9.8         Restrictions.
The Holder acknowledges that the Shares acquired upon the exercise of this Purchase Warrant, if not registered, and the Holder
does not utilize cashless exercise, will have restrictions upon resale imposed by state and federal securities laws.


 


9.9         Severability.
Wherever possible, each provision of this Purchase Warrant shall be interpreted in such manner as to be effective and valid under
applicable law, but if any provision of this Purchase Warrant shall be prohibited by or invalid under applicable law, such provision
shall be ineffective to the extent of such prohibition or invalidity, without invalidating the remainder of such provision or
the remaining provisions of this Purchase Warrant.
