Inc., a Minnesota corporation (the “Company”), and the purchasers listed on Schedule A hereto who
have executed a signature page of the Agreement (each, a “Purchaser” and collectively, the “Purchasers”).
Certain definitions used in this Subscription Agreement shall have the meanings given to them in Section 5 below.


 


WHEREAS, the Company is conducting an offering
(the “Offering”) of an aggregate Offering amount of up to One Million Seven Hundred and Seventy-Five Thousand
Dollars ($1,775,000), involving the sale of up to 71 units, each consisting of (a) $25,000 in Convertible Notes (as defined below); and
(b) detachable warrants (the “Warrants”) to purchase shares of the Company’s common stock (collectively,
the Convertible Notes and the Warrants, the “Units”), for $25,000 per Unit;


 


WHEREAS, subject to the terms and conditions
set forth herein, the Company wishes to issue and sell to each Purchaser, and each Purchaser wishes to purchase from the Company, the
Units in exchange for the consideration (the “Consideration”) set forth opposite such Purchaser’s name
on Schedule A hereto.


 


NOW, THEREFORE, in consideration of the
mutual covenants and agreements hereinafter set forth and for other good and valuable consideration, the receipt and sufficiency of which
are hereby acknowledged, the parties hereto agree as follows:


 


1. DESCRIPTION OF CONVERTIBLE
NOTES, WARRANTS AND COMMITMENT


 


1.1 Description of Convertible
Notes. 


 


Principal Amount; Interest. The
Company has authorized the issuance and sale of Senior Secured Convertible Notes in the aggregate original principal amount of up to
One Million Seven Hundred and Seventy-Five Thousand Dollars ($1,775,000 USD) in substantially the form attached hereto, and with the
terms set forth in, Exhibit A (the “Convertible Notes” and each a “Convertible
Note”), subject to the receipt by the Company or Persons as directed by the Company of the Consideration no later than
the Closing Date. In exchange for each $25,000 of Consideration paid by each Purchaser, the Company will sell and issue to such

applicable Convertible Note (the “Interest”). The Convertible Notes shall be secured pursuant to the terms
of a security agreement in substantially the form attached hereto as Exhibit B (the “Security
Agreement”). The payment of the Convertible Notes and the security interest set forth in the Security Agreement shall
be issued as senior secured debt and have priority over the Subordinated Lender, pursuant to the Subordination Agreement in the form
of Exhibit C hereto (the “Subordination Agreement”).


 






     


     


    

 


1.2 Warrants.


 


Subject to the terms and conditions hereof and
on the basis of the representations and warranties hereinafter set forth, at and subject to the Closing, the Company agrees to issue and
sell to each of the Purchasers, and each of the Purchasers agrees to purchase from the Company, as part of the Units, a Warrant to purchase
that number of shares of Common Stock as calculated as set forth in the introductory paragraph of the Warrant, a form of which is attached
hereto as Exhibit D at an aggregate exercise price calculated as set forth in Section 2(b) of the Warrant, a form of which is attached
hereto as Exhibit D, with an exercise period of five (5) years from the Closing Date (the “Warrant Exercise Period”).


 


1.3 Piggyback Registration Rights. 


 


(a) The
Company covenants and agrees that if, at any time prior to the Registration Rights Expiration Date (defined below), it proposes to file
a registration statement with respect to its common stock (other than in connection with an offering to the Company’s employees
(Form S-8) or in connection with an acquisition, merger or similar transaction (Form S-4)) under the Securities Act in a primary registration
on behalf of the Company, and the registration form to be used may be used for the issuance or resale of (i) the shares underlying the
Convertible Notes (the “Note Shares”), (ii) the shares of Common Stock issuable upon exercise of the Warrants
or (iii) the shares of Common Stock issuable upon exercise of the Warrants (defined in Section 8.9) ((ii) and (iii) collectively,
the “Warrant Shares” and together with the Note Shares, the “Registrable Securities”),
the Company will give prompt written notice to each Purchaser and (name) of its intention to file such registration statement and
will offer to include in such registration statement, such number of Registrable Securities with respect to which the Company has received
written requests for inclusion therein within three (3) Business Days days after the giving of notice by the Company (the “Piggyback
Registration Rights”). If such registration statement is for an underwritten offering, such Registrable Securities shall
be included in the underwriting on the same terms and conditions as the securities otherwise being sold through the underwriters, which
terms and conditions shall be agreed upon between the Company and the underwriters in the Company’s sole discretion. Notwithstanding
the obligations set forth above, if (i) any Securities and Exchange Commission guidance sets forth a limitation on the number of securities
permitted to be registered on a particular registration statement as a secondary offering or (ii) the underwriters in such offering advise
the Company that marketing factors require a limitation on the number of shares to be underwritten, the number of Registrable Securities
to be registered on such registration statement will be reduced pro rata between the Purchasers and other parties whose securities are
included in such registration statement. The “Registration Rights Expiration Date” shall be five years from
the Closing.

(b) Demand
Registration Rights.


 


At any time commencing on the earlier of (1)
ninety (90) days following an IPO (as defined below); and (2) the one year anniversary of the Closing Date, Purchasers holding a
majority in interest of the then outstanding principal amount of the Convertible Notes sold in the Offering (“Majority
In Interest”), shall have the one-time right, by written notice provided to the Company (the “Demand
Notice”), to demand the Company to register for resale all of the Registrable Securities under and in accordance with
the provisions of the Securities Act by filing with the Securities and Exchange Commission (the
“Commission”) a registration statement covering the resale of the Registrable Securities (the
“Demand Registration Statement”). Such Demand Registration Statement shall be (i) filed by the Company
with the Commission no later than sixty (60) days after receipt by the Company of the Demand Notice (the “Demand Filing
Date”), and (ii) the Company shall use commercially reasonable efforts to obtain effectiveness of the Demand
Registration Statement promptly after the Demand Filing Date. The Demand Registration Statement required hereunder shall be on Form
S-1 (except if the Company is eligible to register for resale the Registrable Securities on Form S-3, in which case the Demand
Registration Statement shall be on Form S-3). The Company shall keep the Demand Registration Statement continuously effective, and
the information in the Demand Registration Statement current under Section 10(a) of the Securities Act until the earlier of (i) the
date when all Registrable Securities included in the Demand Registration Statement have been sold pursuant to the Demand
Registration Statement, (ii) the date that the Registrable Securities can be resold without restriction pursuant to Rule 144 of the
Securities Act; and (iii) one (1) year following the end of the Warrant Exercise Period. Notwithstanding the obligations set forth
above, if (x) any Commission guidance sets forth a limitation on the number of securities permitted to be registered on the Demand
Registration Statement (including any other securities included by the Company in such Demand Registration Statement) or (y) the
underwriters in such offering advise the Company that marketing factors require a limitation on the number of shares to be
underwritten, the number of Registrable Securities to be included on such Demand Registration Statement for the benefit of the
Purchasers and (name) will be reduced pro rata between the Participants (and such other parties) whose securities are
included in such Demand Registration Statement; provided further that the Company shall take action to file additional registration
statements at the request of a Majority In Interest, after the effectiveness of the Demand Registration Statement, subject to (i)
Commission rules and guidance and the requirements set forth above and (ii) such underwriters’ advice, until all Registrable
Securities are registered.

Company, confirming their beneficial ownership of Company securities, the owners of any entities holding Company securities which they

Notes have been finally and irrevocably paid in full in accordance with the terms thereof unless waived in writing by the Purchasers:


 


6.1 Preservation of Existence

The Company will preserve and maintain its existence
and all of its leases, privileges, franchises, qualifications and rights that are necessary in the ordinary conduct of its Business.


 


6.2 Pre-emptive Rights.



 


Except in connection with its IPO, if the Company
proposes to offer or sell any Equity Securities for a period of one (1) year following the Closing Date, the Company shall first offer
20% of such Equity Securities to the Purchasers (the “New Securities”) as follows:


 


(a) The
Company shall give notice (the “Offer Notice”) to each Purchaser, stating (i) its bona fide intention to offer

notification to the Company within ten (10) calendar days (the “Offer Period”) after the Offer Notice is given, each
Purchaser may elect in writing (the “Election Notice”) to purchase or otherwise acquire, at the price and on the terms
specified in the Offer Notice, up to that portion of such New Securities which equals the proportion that the Convertible Notes then held
by such Purchaser to all of the then-outstanding Convertible Notes (the “Pro Rata Proportion”). Such Election Notice
shall also set forth the maximum number of New Securities that such Purchaser would be willing to purchase.If any Purchaser(s) fail to

Proportion (the “Overallotment Purchasers”) shall also be allocated that portion of the New Securities for which Purchasers

offer and sell the remaining unsubscribed portion of such New Securities to any Person or Persons at a price not less than, and upon terms
no more favorable to the offeree than, those specified in the Offer Notice. If the Company does not enter into an agreement for the sale
of the New Securities within such period, or if such agreement is not consummated within thirty (30) calendar days of the execution thereof,
the right provided hereunder shall be deemed to be revived and such New Securities shall not be offered unless first reoffered to the
Purchasers in accordance with this Section  6.2(b).

conflict on any material issue between the position of the Company and the position of such Purchaser Party, in which case the
Company shall be responsible for the reasonable fees and expenses of no more than one such separate counsel. The Company will not be
liable to any Purchaser Party under this Agreement or any Other Investor Agreement (y) for any settlement by a Purchaser Party
effected without the Company’s prior written consent, which shall not be unreasonably withheld or delayed; or (z) to the
extent, but only to the extent that a loss, claim, damage or liability is attributable to any Purchaser Party’s breach of any

 8.3 Headings. 


 


The headings of the Sections and Subsections of
this Subscription Agreement are inserted for convenience only and do not constitute a part of this Subscription Agreement.


 


 8.4 Independent Nature of Purchasers’ Obligations and

Agreement and the Other Investor Agreements are several and not joint with the obligations of any other Purchaser, and no Purchaser
shall be responsible in any way for the performance or non-performance of the obligations of any other Purchaser under this
Agreement and the Other Investor Agreements. Nothing contained in this Agreement and the Other Investor Agreements, and no action
taken by any Purchaser pursuant hereto or thereto, shall be deemed to constitute the Purchasers as a partnership, an association, a
joint venture or any other kind of entity, or create a presumption that the Purchasers are in any way acting in concert or as a
group with respect to such obligations or the transactions contemplated by this Agreement and the Other Investor Agreements. Each
Purchaser shall be entitled to independently protect and enforce its rights including, without limitation, the rights arising out of
this Agreement and the Other Investor Agreements, and it shall not be necessary for any other Purchaser to be joined as an
additional party in any Proceeding for such purpose. Each Purchaser has been represented by its own separate legal counsel in its
review and negotiation of this Agreement and the Other Investor Agreements. For reasons of administrative convenience only, each
Purchaser and its respective counsel have chosen to communicate with the Company through (name). The (name) does not
represent any of the Purchasers and only represents (name). The Company has elected to provide all Purchasers with the same
terms and agreements for the convenience of the Company and not because it was required or requested to do so by any of the
Purchasers. It is expressly understood and agreed that each provision contained in this Agreement and the Other Investor Agreements
is between the Company and a Purchaser, solely, and not between the Company and the Purchasers collectively and not between and
among the Purchasers.

by .pdf, .tif, .gif, .peg or similar attachment to electronic mail (any such delivery, an “Electronic Delivery”) shall
be treated in all manner and respects as an original executed counterpart and shall be considered to have the same binding legal effect
as if it were the original signed version thereof delivered in person. No party shall raise the use of Electronic Delivery to deliver
a signature or the fact that any signature or agreement or instrument was transmitted or communicated through the use of Electronic Delivery
as a defense to the formation of a contract, and each such party forever waives any such defense, except to the extent such defense relates
to lack of authenticity.

of the remaining provisions contained herein and therein, and any other application thereof, shall not in any way be affected or impaired

of this Agreement shall be deemed to be a continuing waiver in the future or a waiver of any subsequent default or a waiver of any other
provision, condition or requirement hereof, nor shall any delay or omission of any party to exercise any right hereunder in any manner
impair the exercise of any such right. Any proposed amendment or waiver that disproportionately, materially and adversely affects the
rights and obligations of any Purchaser relative to the comparable rights and obligations of the other Purchasers shall require the prior
written consent of such adversely affected Purchaser. Any amendment effected in accordance with this Section 8.11 shall be binding upon
each Purchaser and holder of Securities and the Company.

CERTIFICATION OF ACCREDITED INVESTOR STATUS


 


By indicating where applicable below, the undersigned
represents, warrants and certifies that he, she or it is an “accredited investor,” as that term is defined in
Rule 50119 of Regulation D of the Securities Act of 1933, as amended (the “Securities Act”). The
undersigned has initialed the line below indicating the basis on which he, she or it is representing his, her or its status as an “accredited
investor” at the request of EPIEN Medical, Inc., a Minnesota corporation (the “Company”). The
representation and confirmation below as part of this Certification of Accredited Investor Status (the “Certification”)
shall be effective for all purposes and shall be able to be relied upon by the Company, its legal counsel and assigns for any and all
purposes, until such time, if ever, as the undersigned has advised the Company that the representations below are no longer accurate or
correct.


 


By initializing below the undersigned confirms,
acknowledges and represents that he, she or it, is an “accredited investor” because he, she or it is (please
initial on the applicable line):


 


	—	a bank as defined in Section 3 (a)(2) of the Securities Act, or any savings and loan association or other institution as defined in Section 3(a)(5)(A) of the Securities Act whether acting in its individual or fiduciary capacity; a broker or dealer registered pursuant to Section 15 of the Securities Exchange Act of 1934, as amended (the “Exchange Act”); an insurance company as defined in Section 2(13) of the Securities Act; an investment company registered under the Investment Company Act of 1940 or a business development company as defined in Section 2(a)(48) of that Act; a small business investment company licensed by the U.S. Small Business Administration under Section 301(c) or (d) of the Small Business Investment Act of 1958; a plan established and maintained by a state, its political subdivisions, or any agency or instrumentality of a state or its political subdivisions, for the benefit of its employees, and such plan has total assets in excess of $5,000,000; an employee benefit plan within the meaning of the Employee Retirement Income Security Act of 1974, if the investment decision is made by a plan fiduciary, as defined in Section 3(21) of such Act, which is either a bank, savings and loan association, insurance company, or registered investment adviser, or if the employee benefit plan has total assets in excess of $5,000,000 or, if a self-directed plan, with investment decisions made solely by persons that are “accredited  investors”;
	 	 
	—	a private business development company as defined in Section 202(a)(22) of the Investment Advisers Act of 1940;



 


 






	19	http://www.law.cornell.edu/cfr/text/17/230.501



 




     


     


    

 


	—	an organization described in Section 501 (c)(3) of the Internal Revenue Code, corporation, Massachusetts or similar business trust, or partnership, not formed for the specific purpose of acquiring the securities offered, with total assets in excess of $5,000,000;
	 	 
	—	a natural person whose individual net worth, or joint net worth with the undersigned’s spouse, at the time of this purchase exceeds $1,000,000. For purposes of this item, “net worth” means the excess of total assets at fair market value (including personal and real property, but excluding the estimated fair market value of a person’s primary home) over total liabilities. Total liabilities exclude any mortgage on the primary home in an amount of up to the home’s estimated fair market value as long as the mortgage was incurred more than 60 days before the subscription date, but includes (i) any mortgage amount in excess of the home’s fair market value and (ii) any mortgage amount that was borrowed during the 60-day period before the subscription date;
	 	 
	—	a natural person who had an individual income in excess of $200,000 in each of the two most recent years or joint income with the undersigned’s spouse in excess of $300,000 in each of those years and has a reasonable expectation of reaching the same income level in the current year. “Income” for this purpose is computed by adding the following items to adjusted gross income for federal income tax purposes: (a) the amount of any tax-exempt interest income received; (b) the amount of losses claimed as a limited partner in a limited partnership; (c) any deduction claimed for depletion; (d) deductions for alimony paid; (e) deductible amounts contributed to an IRA or Keogh retirement plan; and (f) any amount by which income from long-term capital gains has been reduced in arriving at adjusted gross income pursuant to the provisions of Section 1202 of the Internal Revenue Code;
	 	 
	—	A revocable trust that has more than $5 million in assets, not formed for the purpose of acquiring the shares, and its trustee is a sophisticated person (under Rule 501(a)(7))21.
	 	 
	—	An irrevocable trust that has more than $5 million in assets, was not formed for the purpose of investing in the Company, and its trustee is a sophisticated person13 (under Rule 501(a)(7)).
	 	 
	—	an entity (other than a trust) in which all of the equity holders are “accredited investors” by virtue of their meeting one or more of the above standards, not formed for the specific purpose of acquiring any securities of the Company.
	 	 
	—	an executive officer of EPIEN Medical, Inc., a Minnesota corporation.

such knowledge and experience in financial and business matters that he or she is capable of evaluating the merits and risks of a prospective
investment.



 






     


     


    

 


The undersigned (the “Subscriber”)
hereby represents and warrants to the Company that Subscriber has not incurred any debt secured by Subscriber’s primary residence
for the purpose of inflating Subscriber’s net worth to qualify as an accredited investor or for the purpose of raising funds to
invest in any securities of the Company. Between the date of this Certification and the date if any on which Subscriber invests in the
Securities, Subscriber does not intend to, and will not, incur any debt to be secured by Subscriber’s primary residence for the
purpose of either inflating Subscriber’s net worth to qualify as an accredited investor or raising funds to invest in the Securities.


 


The undersigned agrees that the Company is relying

forth herein. All information which the undersigned has provided to the Company is true and correct and does not contain any untrue statement

THIS NOTE, AND THE SECURITIES ISSUABLE UPON CONVERSION OF THIS NOTE
(THE “SECURITIES”) HAVE BEEN ACQUIRED FOR INVESTMENT PURPOSES ONLY AND MAY NOT BE TRANSFERRED UNTIL (i) A REGISTRATION
STATEMENT UNDER THE SECURITIES ACT OF 1933, AS AMENDED (THE “ACT” OR THE “SECURITIES ACT”) SHALL
HAVE BECOME EFFECTIVE WITH RESPECT THERETO OR (ii) RECEIPT BY THE COMPANY OF AN OPINION OF COUNSEL REASONABLY SATISFACTORY TO THE COMPANY
TO THE EFFECT THAT REGISTRATION UNDER THE ACT IS NOT REQUIRED IN CONNECTION WITH SUCH PROPOSED TRANSFER NOR IS IN VIOLATION OF ANY APPLICABLE
STATE SECURITIES LAWS. THIS LEGEND SHALL BE ENDORSED UPON ANY NOTE ISSUED IN EXCHANGE FOR THIS NOTE AND ANY SECURITIES ISSUABLE UPON CONVERSION
OF THIS NOTE (EXCEPT AS OTHERWISE PROVIDED BELOW).


 


SECURED CONVERTIBLE PROMISSORY NOTE 


 


Effective
(date)


 


FOR VALUE RECEIVED, EPIEN Medical, Inc.,
a Minnesota corporation (the “Company” or the “Borrower”), hereby promises to
pay to the order of _______________________________ , a _____________ and/or its permitted assigns (the
“Holder”), the aggregate principal amount of $_________________________ (the
“Principal”), together with interest on the unpaid Principal amount hereof, upon the terms and
conditions hereinafter set forth. This Secured Convertible Promissory Note is defined herein as the
“Note”. The “Effective Date” of this Note shall be (date). This Note is
issued and all rights hereunder shall be held subject to all of the conditions, limitations and provisions set forth herein. Certain
capitalized terms used herein have the meanings given to them in that certain Subscription Agreement dated (date) between the
Company and certain accredited investors named therein (the “Subscription Agreement”).


 


		1.	Payment Terms. The balance of Principal, together
with any accrued and unpaid interest due hereunder shall be due and payable on the earlier of (i) (date), (ii) the date the Holder
has effected an Acceleration, (iii) the date that Holder has effected a Default Acceleration; or (iv) the date that Holder has effected
a Change of Control Acceleration (the earlier of (i), (ii), (iii), and (iv), the “Maturity Date”), unless this
Note is earlier converted as set forth below. This Note is one of the Senior Secured Convertible Promissory Notes (the “Notes”)
issued by the Company pursuant to the Subscription Agreement. This Note may not be prepaid prior to the Maturity Date without the prior
written consent of the Holder. In the event that this Note is repaid prior to the first anniversary of the Effective Date (either due
to an Acceleration, Default Acceleration, a Capital Raise or Change of Control Acceleration, or with the written consent of the Holder),
the Company shall pay the Holder a pre-payment penalty equal to (a) 10% of the original Principal amount of this Note, less (b) Interest
which has accrued under this Note through such date of prepayment and been paid to the Holder (the “Pre-Payment Penalty”).

		2.	Interest. Interest
on the outstanding Principal of this Note shall accrue at a rate of (percent) per annum (“Interest”),
compounded annually, and shall be due and payable on the earlier of (a) the Maturity Date, and (b) the date this Note has been completely
converted (payable in shares of common stock). All past-due Principal and Interest shall bear Interest at the rate of eighteen percent
(18%) per annum until paid in full (the “Default Rate”). Interest shall be computed on the basis of the actual
number of days elapsed and a year of 365 days.



 


(a) Notwithstanding
any provision in this Note, the total liability for payments of Interest and payments in the nature of interest, including all charges,
fees, exactions, or other sums which may at any time be deemed to be interest, shall not exceed the limit imposed by the usury laws of
the State of Minnesota or the applicable laws of the United States of America, whichever shall be higher (the “Maximum Rate”).


 


(b) In
the event the total liability for payments of Interest and payments in the nature of interest, including, without limitation, all charges,
fees, exactions or other sums which may at any time be deemed to be interest, which for any month or other interest payment period exceeds
the Maximum Rate, all sums in excess of those lawfully collectible as interest for the period in question (and without further agreement
or notice by, among or to the Holder the undersigned) shall be applied to the reduction of the Principal balance, with the same force
and effect as though the undersigned had specifically designated such excess sums to be so applied to the reduction of the Principal balance
and the Holder had agreed to accept such sums as a premium-free prepayment of Principal; provided, however, that the Holder may, at any
time and from time to time, elect, by notice in writing to the undersigned, to waive, reduce or limit the collection of any sums in excess
of those lawfully collectible as interest rather than accept such sums as a prepayment of the Principal balance. The undersigned does
not intend or expect to pay nor does the Holder intend or expect to charge, accept or collect any interest under this Note greater than
the Maximum Rate.


 


(c) If
any payment of Principal or interest on this Note shall become due on a Saturday, Sunday or any other day on which national banks are
not open for business, such payment shall be made on the next succeeding Business Day. “Business Day” means
a day other than (i) a Saturday, (ii) a Sunday or (iii) a day on which commercial banks in Minnesota, are authorized or required to be
closed for business.

	 	3.	Conversion of this Note.


 


(a) The
unpaid Principal balance of this Note, together with all accrued and unpaid Interest and as applicable, the Pre-Payment Penalty (such
amount converted by the Holder, the “Aggregate Amount Converted”), is convertible at the option of the Holder,
from time to time, following a Qualified Financing, into that number of shares of Common Stock (the “Shares”)
as equals the Aggregate Amount Converted divided by 85% of the Public Offering Price, subject to adjustment as discussed herein (the “Conversion
Price”)(each a “Conversion” and such option, the “Holder Conversion Option”).
In the event that the Conversion occurs within one year of the Effective Date, the Pre-Payment Penalty shall also be deemed due and payable,
and such Pre-Payment Penalty may also be converted into Common Stock pursuant to this Section 3(a).


 


(b) “Public
Offering Price” means the actual or implied price per share of Common Stock paid by the purchasers of the Qualified Offering
Securities sold in the Qualified Financing, as reasonably determined by the board of directors of the Company.


 


(c) “Qualified
Financing” means the closing of the Company’s first sale of its Common Stock to the public after the date of this
Note (including as part of a unit or in the form of, or as part of, a convertible security), in an offering underwritten by an investment
banking firm, pursuant to an effective registration statement under the Securities Act, which results in the Common Stock being listed
on a national securities exchange or NASDAQ, or quoted on the OTCQB or OTCQX market.


 


(d) “Qualified
Offering Securities” means the equity securities issued by the Company in the Qualified Financing.


 


(e) Following
Qualified Financing, the Company shall within ten (10) Business Days, notify the Holder that a Qualified Financing has occurred, at the
address of Holder which the Company then has on record.


 


(f) In
order to exercise the Holder Conversion Option, the Holder shall provide the Borrower a written notice of its intentions to exercise the
Holder Conversion Option, which notice shall set forth the amount of this Note to be converted and the applicable Principal, Interest
and the applicable Principal and Interest and if applicable, Pre-Payment Penalty to be converted and the calculation of the applicable
Conversion Price, which shall be in the form of Schedule A, attached hereto (“Notice of Conversion”).

(g) The
Company shall cause the Shares received upon exercise of the Holder Conversion Option hereunder to be transmitted by its transfer agent
(the “Transfer Agent”) to the Holder by crediting
the account of the Holder’s or its designee’s balance account with The Depository Trust Company through its Deposit or Withdrawal
at Custodian system (“DWAC”) if the Borrower is then a participant in such system and either (A) there is an effective registration
statement permitting the issuance of the Shares to or resale of the Shares by the Holder or (B) the Shares are eligible for resale by
the Holder without volume or manner-of-sale limitations pursuant to Rule 144, and otherwise by physical delivery of a certificate, registered
in the Company’s share register in the name of the Holder or its designee, for the number of Shares to which the Holder is entitled
pursuant to such exercise to the address specified by the Holder in the Notice of Exercise by the date that is two (2) Trading Days after
the delivery to the Company of the Notice of Conversion (such date, the “Share Delivery Date”). Upon delivery
of the Notice of Conversion, the Holder shall be deemed for all corporate purposes to have become the holder of record of the Shares with
respect to which this Note has been converted, irrespective of the date of delivery of the Shares.


 


(h) Notwithstanding
the foregoing, If the Borrower reasonably believes that there is an error in Holder’s calculation of the Shares issuable in connection
with the Notice of Conversion or the Conversion Price provided for therein, or another issue with the conversion, the Borrower shall not
be obligated to honor such defective Notice of Conversion and shall promptly notify Holder of such errors.


 


(i) Notwithstanding
anything herein to the contrary, the Holder shall not be required to physically surrender this Note to the Borrower until the Holder has
converted the entire amount of this Note, in which case, the Holder shall surrender this Note to the Borrower for cancellation within
three (3) Business Days of the date the final Notice of Conversion is delivered to the Borrower. Partial conversions of this Note shall
have the effect of lowering the outstanding Principal and Interest due on this Note, as applicable. The Holder and the Borrower shall
maintain records showing the actual Principal and Interest on this Note, provided that absent manifest error, the Borrower’s records
shall control.


 


(g) The
Borrower shall at all times take any and all additional actions as are necessary to maintain the required authority to issue the Shares
to the Holder, in the event the Holder exercises its rights under the Holder Conversion Option.


 


(h) Following
the effective time of any Conversion, all rights of any Holder with respect to the amount of this Note converted, will terminate, except
only for the rights of any such Holder to receive certificates (if the Borrower generally issues certificates) for the number of Shares
which this Note has been Converted.

	 	4.	General Provisions Relating to the Shares and Conversions.



 


(a) Conversion
calculations pursuant to Section 3, shall be rounded to the nearest whole share of Common Stock.


 


(b) If
the Borrower at any time or from time to time on or after the Effective Date effects a subdivision of its outstanding Common Stock, the
Conversion Price then in effect immediately before that subdivision shall be proportionately decreased, and conversely, if the Borrower
at any time or from time to time on or after the Effective Date combines its outstanding shares of Common Stock into a smaller number
of shares, the Conversion Price then in effect immediately before the combination shall be proportionately increased.


 


(c) The
Company shall not effect any exercise of the Holder Conversion Option and a Holder shall not have the right to convert any portion of
this Note to the extent that after giving effect to such issuance after exercise as set forth on the applicable Notice of Conversion,
the Holder (together with the Holder’s Affiliates, and any other Persons acting as a group together with the Holder or any of the
Holder’s Affiliates (such Persons, “Attribution Parties”)), would beneficially own in excess of the Beneficial Ownership
Limitation (as defined below). 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 the Holder
Conversion Option 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, nonconverted portion of this Note owned by the Holder or any of its Affiliates or
Attribution Parties and (ii) exercise or conversion of the unexercised or nonconverted portion of any other securities of the Company
(including, without limitation, any other Common Stock equivalents) subject to a limitation on conversion or exercise analogous to the
limitation contained herein beneficially owned by the Holder or any of its Affiliates or Attribution Parties. Except as set forth in the
preceding sentence, for purposes of this Section 4(c), beneficial ownership shall be calculated in accordance with Section 13(d) of the
Exchange Act and the rules and regulations promulgated thereunder, it being acknowledged by the Holder that the Company is not representing
to the Holder that such calculation is in compliance with Section 13(d) of the Exchange Act and the Holder is solely responsible for any
schedules required to be filed in accordance therewith. To the extent that the limitation contained in this Section 4(c) applies, the
determination of whether the Holder Conversion Option is exercisable (in relation to other securities owned by the Holder together with
any Affiliates and Attribution Parties) and of which portion of this Note is convertible shall be in the sole discretion of the Holder,
and the submission of a Notice of Conversion shall be deemed to be the Holder’s determination of whether this Note is convertible
(in relation to other securities owned by the Holder together with any Affiliates and Attribution Parties) and of which portion of this
Note is convertible, 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 4(c), 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’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. 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. 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 Note, 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 “Beneficial Ownership Limitation” shall be 4.99% of the number of shares of the Common Stock
outstanding immediately after giving effect to the issuance of shares of Common Stock issuable upon conversion of this Note. The limitations
contained in this paragraph shall apply to a successor holder of this Note.

	 	5.	Acceleration and Change of Control Acceleration.


 


(a) At
the option of the Holder, at any time after the earlier of (i) the date that the Company has completed a subsequent capital raise or capital
raises (whether through the sale of debt or equity) in the aggregate amount of at least $10 million after the date of this Note; or (ii)
has completed a Qualified Financing, the Holder may, by written notice to the Borrower, declare the Principal amount then outstanding
of, and the accrued Interest and all other amounts payable on (including where applicable, the Pre-Payment Penalty) this Note to be immediately
due and payable (an “Acceleration”)


 


(b) If
a Change of Control (as defined below) occurs and the Holder has not approved such Change of Control in writing (unless such Change of
Control has been waived by Holder), Holder shall have the right, by written notice to the Company, to declare the entire amount of this
Note, including all Principal and Interest and Pre-Payment Penalty immediately due and payable (a “Change of Control Acceleration”).
“Change of Control” means (i) the completion by the Company of a plan of merger or consolidation of the Company
with any other Person as a result of which the holders of the voting capital stock of the Company as a group would receive less than 50%
of the voting capital stock of the surviving or resulting corporation or entity; (ii) the closing of a transaction
involving the Company providing for the sale or transfer of substantially all the assets of the Company; or (iii) the acquisition of more
than 50% of the Company’s voting capital stock by any person within the meaning of Rule 13d-3 under the Exchange Act (other than
the Company or a Person that directly or indirectly controls, is controlled by, or is under common control with, the Company), in each
case unless approved by the written consent of the Holder.

been cured within ten (10) days from the date that the Holder has provided the Borrower written notice of such breach; or


 


(c) Borrower
shall: (i) become insolvent or take any action which constitutes its admission of inability to pay its debts as they mature; (ii) make

(d) Borrower
shall take any action authorizing, or in furtherance of, any of the foregoing.


 


In case any one or more Events of Default shall
occur and be continuing, the Holder, may proceed to protect and enforce the rights of the Holder by an action at law, suit in equity or
other appropriate proceeding, whether for the specific performance of any agreement contained herein or for an injunction against a violation
of any of the terms hereof, or in aid of the exercise of any power granted hereby or thereby or by law or otherwise, and shall also be
authorized to take all actions to enforce the security interest set forth in the Security Agreement. In case of a default in the payment
of any Principal of or premium, if any, or Interest on this Note, Borrower will pay to the Holder such further amount as shall be sufficient
to cover the reasonable cost and expenses of collection, including, without limitation, reasonable attorneys’ fees, expenses and
disbursements. No course of dealing and no delay on the part of the Holder in exercising any right, power or remedy shall operate as a
waiver thereof or otherwise prejudice the Holder’s rights, powers or remedies. No right, power or remedy conferred by this Note
upon the Holder shall be exclusive of any other right, power or remedy referred to herein or therein or now or hereafter available at
law, in equity, by statute or otherwise.


 


		8.	Assignment and Transfer
by Holder. If and whenever this Note shall be
assigned and transferred, or negotiated, including transfers to substitute or successor trustees, in each case subject to applicable
law and the availability of an exemption from registration for such transfer, which shall be approved by the Company subject to the Holder
providing the Company a legal opinion for such transfer, which opinion shall be reasonably accepted by the Company, the holder hereof
shall be deemed the “Holder” for all purposes under this Note.

of the tangible assets and beneficial use of all the Collateral and may use it in any lawful manner not inconsistent with this Security
Agreement, provided that Borrower’s right to possession and beneficial use shall not apply to any Collateral where possession of
the Collateral by the Secured Parties is required by law to perfect the Secured Parties’ security interest in such Collateral. The
Secured Parties shall not be required to take any steps necessary to preserve any rights in the Collateral against prior parties, neither
to protect nor to preserve nor to maintain any security interest given to secure the indebtedness.


 


7) Rights,
Powers and Limitation of Liability.


 


a) Appointment
as Borrower’s Attorney-in-Fact. Borrower hereby irrevocably appoints the Security Agent as Borrower’s agent and attorney-in-fact,
with full power in Borrower’s name or its own name and at Borrower’s expense, and whether the Security Agent acts directly
or through one or more of its representatives, to execute, endorse and deliver any and all agreements, assignments, pledges, instruments,
documents, and any other writings, and to take any and all other actions, which a Majority In Interest may in its sole discretion deem
necessary or desirable to effect the terms and purposes of this Security Agreement, including without limitation: (i) to take any action
which the Security Agent is authorized to take under Section 6(b) hereof in the event Borrower fails to perform or comply with any of its duties, covenants or agreements hereunder; and
(ii) to exercise, during the continuation of an Event of Default, any and all rights and remedies specified in Section 7 hereof.
This power, being coupled with an interest, shall be irrevocable until the Obligations are paid and performed in full;

b) Right to Perform for
Borrower. If Borrower fails at any time to perform or comply with any of its obligations, covenants or agreements hereunder, the
Security Agent may (but shall not be obligated to) take such action, in its own name or as the Borrower’s attorney-in-fact as
provided in Section 7(a) hereof, as a Majority In Interest shall deem necessary or desirable to effect such performance or
compliance, including without limitation: (i) the preservation and maintenance of the Collateral and the payment, discharge, contest
and/or settlement of any and all taxes and third-party claims and charges; (ii) the removal or avoidance of the imposition of liens
against any or all of the Collateral; (iii) the timely collection of payments due and the enforcement of remedies available under or
with respect to the Collateral and related warranties and other agreements; and (iv) the execution and filing (to the extent
permitted under the UCC and other applicable law) of financing and continuation statements and amendments and other documents with
appropriate governmental authorities;


 


c) Limitation
of Liability. Borrower agrees that the Secured Parties shall have no obligation to exercise any of their rights, powers and remedies
hereunder and no liability to Borrower or any other person for not doing so. Borrower further agrees that to the extent the Secured Parties
do exercise any of such rights, powers or remedies (i) the Secured Parties shall be accountable to Borrower and/or any other persons only
for amounts they actually receive as the result of such exercise (and not for amounts to which it is or may be entitled or which it might
have received had it elected to take additional action) and (ii) neither the Secured Parties nor any of their representatives shall have
any liability to Borrower or any other person for any act or omission in connection with such exercise except for (A) the Secured Parties’
or any such representative’s failure to exercise reasonable care as required under the UCC or to otherwise comply with UCC provisions
or (B) the Secured Parties’ or any such representative’s willful misconduct.


 


8) Default.
Each of following shall constitute an “Event of Default” under this Security Agreement:


 


a) Payment
Default. Borrower fails to make any payment when due under the Notes or in connection with any of the other Obligations;


 


b) Other
Defaults. An Event of Default occurs under the Notes or the Borrower fails to comply with or to perform any other material term, obligation,
covenant or condition contained in this Security Agreement or the Notes;


 


c) Default
in Favor of Third Parties. In the event that Borrower defaults under any loan, extension of credit, security agreement, purchase and
sale agreement, or any other agreement, in favor of any other creditor or person that may materially affect any of Borrower’s assets or Borrower’s ability to repay the Notes
or perform its respective obligations under this Security Agreement or any of the other Obligations which default is not cured within
ten (10) days.


 


Security Agreement


 



    Page 8 of 16


     


    

 


d) Defective
Collateralization. This Security Agreement ceases to be in full force and effect, including failure of any collateral document to
create a valid and perfected security interest or line, at any time and for any reason;


 


e) False
Statements. Any warranty, representation, or statement made or furnished to the Secured Parties by Borrower or on Borrower’s
behalf is false or misleading in any material respect, either now or at the time made or furnished ;


 


f) Bankruptcy.
The appointment of a receiver for any part of Borrower’s assets, any assignment for the benefit of creditors, any type of creditor
workout, or the commencement of any proceeding under any bankruptcy or insolvency laws by or against Borrower; and/or


 


g) Creditor
or Forfeiture Proceedings. Commencement of foreclosure or forfeiture proceedings, whether by judicial proceeding, self-help, repossession
or any other method, by any creditor of Borrower or by any governmental agency against any collateral securing the indebtedness. This
includes a garnishment of any of Borrower’s accounts.


 


9) Rights
and Remedies on Default. If an Event of Default occurs under this Security Agreement, at any time thereafter, the Secured Parties
shall have all the rights of a secured party under the UCC. In addition, and without limitation, the Secured Parties may exercise any
one or more of the following rights and remedies:


 


a) all
obligations under the Notes and hereunder may (notwithstanding any provisions thereof), at the option of a Majority In Interest and without
demand, notice or legal process of any kind, be declared, and immediately shall become, due and payable;


 


b) without
notice, demand or legal process of any kind, the Security Agent may take possession of any or all of the Collateral (in addition to Collateral
of which it already has possession), wherever it may be found, and for that purpose may pursue the same wherever it may be found, and
may, without a breach of the peace, enter into any of Borrower’s premises where any of the Collateral may be or be supposed to be,
and search for, take possession of, remove, keep and store any of the Collateral until the same shall be sold or otherwise disposed of,
and the Security Agent shall have the right to store the same in any of Borrower’s premises without cost to the Secured Parties,
and the Security Agent may exercise from time to time any rights and remedies available to it under applicable law, including the UCC,
in addition to, and not in lieu of, any rights and remedies expressly granted in this Security Agreement or in any other instrument or
agreement executed by Borrower;


 


c) at
the Security Agent’s request, Borrower will, at Borrower’s expense, assemble the Collateral at one or more places, reasonably
convenient to both parties, where the Collateral may, at a Majority In Interest’s option, remain,
at Borrower’s expense, pending sale or other disposition thereof;


 


Security Agreement


 



    Page 9 of 16


     


    

 


d) the
Security Agent may, at any time in a Majority In Interest’s discretion, transfer any Collateral into the name of the Security Agent
or any agent thereof or that of the Security Agent’s nominee, and the Security Agent may with the consent of a Majority In Interest,
pursuant to Section 7(a) of this Security Agreement, execute any such documents as may be necessary to effectuate said change, each case
subject to applicable law;


 


e) the
Secured Parties shall have the right, either itself or through a receiver, to: (i) collect the payments, rents, income, or revenues from
the Collateral and hold the same as security for the amounts due under the Notes or apply it to payment of the indebtedness under the
Notes in such order of preference as a Majority In Interest may determine; (ii) notify any account debtor that accounts have been assigned
to the Secured Parties and that the Secured Parties have a security interest therein; (iii) direct all such account debtors to make payments
to the Secured Parties of all or any part of the sums owing Borrower by such account debtor; (iv) enforce collection of any of the accounts
by suit or otherwise; (v) surrender, release or exchange all or any part of said accounts; or (vi) compromise, settle, extend or renew
for any period (whether or not longer than the original period) any indebtedness thereunder or evidenced thereby;


 


f) the
Secured Parties shall have the full power to sell, lease, transfer, or otherwise deal with the Collateral or proceeds thereof in the Secured
Parties’ own name or their agent or that of Borrower, all in accordance with the UCC. The Secured Parties may sell the Collateral
at public auction or private sale. Unless the Collateral threatens to decline speedily in value or of a type customarily sold on a recognized
market, the Secured Parties shall give Borrower, as required by law, reasonable notice of the time and place of any public sale or the
time after which any private sale or any other disposition of the Collateral is to be made. The requirements of reasonable notice shall
be met if such notice is given at least ten (10) days before the time of the sale or disposition. All expenses relating to the disposition
of the Collateral, including without limitation the expenses of retaking, holding, insuring, preparing for sale and selling the Collateral,
shall become a part of the indebtedness secured by this Security Agreement and shall be payable on demand, with interest at the Default
Rate (as defined in the Notes) from date of expenditure until repaid. Any proceeds of any sale, lease or other disposition by the Secured
Parties of any of the Collateral shall be applied as follows: (i) first, to the payment of the Secured Parties’ reasonable expenses
in connection with the Collateral, including reasonable attorneys’ fees and legal expenses; (ii) second, to the payment of all other
obligations in such manner as a Majority In Interest may deem advisable; and (iii) third, the balance, if any, to or at the direction
of Borrower. Borrower shall remain liable for any deficiency; and/or


 


g) except
as may be prohibited by applicable law, all of the Secured Parties’ rights and remedies, whether evidenced by this Security Agreement
or other writing, shall be cumulative and may be exercised singularly or concurrently. Election by a Majority In Interest to pursue any remedy shall not exclude pursuit of any other
remedy, and an election to make expenditures or to take action to perform an obligation of Borrower under this Agreement, after Borrower’s
failure to perform, shall not affect the Secured Parties’ right to declare a default and exercise their remedies.


 


Security Agreement

10) Term.


 


a) This
Security Agreement shall continue in full force and effect until each and all of the obligations under the Notes have been paid and discharged
in full, whereupon (subject to Section 10(b) below) this Security Agreement shall automatically terminate. Such termination shall
not in any way affect or impair the rights and obligations of the parties hereto relating to any transactions or events prior to such
termination, and all indemnities by Borrower shall survive such termination.


 


b) If
after receipt of any payment of, or the proceeds of any Collateral for, all or any part of the obligations, the Secured Parties are compelled
to surrender or voluntarily surrender such payment or proceeds to any person because such payment or application of proceeds is or may
be avoided, invalidated, recaptured, or set aside as a preference, fraudulent conveyance, impermissible setoff or for any other reason,
whether or not such surrender is the result of (i) any judgment, decree or order of any court or administrative body having jurisdiction
over the Secured Parties, or (ii) any settlement or compromise by the Secured Parties of any claim as to any of the foregoing with any
person (including the primary obligor with respect to any of the Obligations), then the Obligations or part thereof affected shall be
reinstated and continue and this Security Agreement shall be reinstated and continue in full force as to such Obligations or part thereof
as if such payment or proceeds had not been received, notwithstanding any previous cancellation of any instrument evidencing any such
Obligation or any previous instrument delivered to evidence the satisfaction thereof or the termination of this Security Agreement.


 


c) This
Agreement, any and all security interests and any and all rights and powers granted to Secured Parties under this Agreement shall automatically
terminate and be of no further force and effect upon the payment in full of the amounts due Secured Parties under the Notes (the “Termination
Date”). Secured Parties hereby irrevocably constitute and appoint Borrower and any officer or agent thereof, with full power
of substitution, as its true and lawful attorney-in-fact with full irrevocable power and authority in place and stead of Secured Parties
and in the name of Secured Parties or in their own name, immediately upon the Termination Date, for the exclusive purpose of filing (a)
a Termination Statement on Form UCC 3 (or any successor form) and (b) any other documents necessary or desirable to evidence the termination
of any and all security interests held by Secured Parties.


 


11) Notices.
All notices, approvals, consents, requests, and other communications hereunder shall be in writing and shall be delivered (i) by personal
delivery, or (ii) by national overnight courier service, or (iii) by certified or registered mail, return receipt requested, or (iv) via
facsimile transmission, with confirmed receipt, or (v) via email. Notice shall be effective upon receipt except for notice via fax (as
discussed above) or email, which shall be effective only when the recipient, by return or reply email or notice delivered by other
method provided for in this Section 10, acknowledges having received that email (with an automatic “read receipt”
or similar notice not constituting an acknowledgement of an email receipt for purposes of this Section 10, but which acknowledgement
of acceptance shall include cases where recipient ‘replies’ to such prior email, including the body of the prior email in
such ‘reply’). Such notices shall be sent to the applicable party or parties at the address specified on the signature page
hereof, subject to notice of changes thereof from any party with at least ten (10) business days’ notice to the other parties. Rejection
or other refusal to accept or the inability to deliver because of changed address of which no notice was given shall be deemed to be receipt
of the notice as of the date of such rejection, refusal or inability to deliver.


 


Security Agreement

12) Modifications.
This Security Agreement, together with any related documents constitutes the entire understanding and agreement of the parties as to the
matters set forth in this Security Agreement. No alteration of or amendment to this Security Agreement shall be effective unless given
in writing and signed by the party or parties sought to be charged or bound by the alteration or amendment.


 


13) Attorney’s
Fees. Borrower shall pay or reimburse the Secured Parties on demand for all costs and expenses (including without limitation reasonable
attorneys’ fees and legal expenses) paid or incurred by the Secured Parties in exercising or enforcing any of their rights, powers
and remedies under this Security Agreement and for all other costs and expenses which the Secured Parties have or shall have paid by reason
of Borrower’s failure or refusal to do so as and when required hereunder. The amount of any such cost or expense shall be repayable
on demand and, until repayment, all such expenditures incurred or paid by the Secured Parties for such purposes will bear interest at
the Default Rate set forth in the Notes from the date incurred or paid by the Secured Parties to the date of repayment by Borrower. All
such expenses will become a part of the Debt.


 


14) No
Waiver by the Secured Parties. The Secured Parties shall not be deemed to have waived any rights under this Security Agreement
unless such waiver is given in writing and signed by the Security Agent on behalf of a Majority In Interest. No delay or omission on the
part of the Secured Parties or a Majority In Interest in exercising any right shall operate as a waiver of such right or any other right.
A waiver by a Majority In Interest of a provision of this Security Agreement shall not prejudice or constitute a waiver of the Secured
Parties’ right otherwise to demand strict compliance with that provision or any other provision of this Agreement. Neither prior
waiver by a Majority In Interest nor any course of dealing between the Secured Parties or a Majority In Interest and Borrower shall constitute
a waiver of any of the Secured Parties’ or a Majority In Interest’s rights or of any of Borrower’s obligations as to
any future transactions. Whenever the consent of the Secured Parties or a Majority In Interest is required under this Security Agreement,
the granting of such consent by the Secured Parties or a Majority In Interest in any instance shall not constitute continuing consent
to subsequent instances where such consent is required, and in all cases such consent may be granted or withheld in the sole discretion
of the Secured Parties or a Majority In Interest.


 


15) Successors
and Assigns. Subject to any limitations stated in this Agreement on transfer of Borrower’s interest, this Security Agreement
shall be binding upon and inure to the benefit of the parties, their successors, and assigns, provided, however,
that Borrower shall not assign or otherwise transfer any of its rights, interests or obligations hereunder without a Majority In Interest’s
prior written consent. If ownership of the Collateral becomes vested in a person other than Borrower, the Secured Parties or a Majority
In Interest, as applicable, without notice to Borrower, may deal with Borrower’s successors with reference to this Security Agreement
and the indebtedness by way of forbearance or extension without releasing Borrower from the obligations of this Security Agreement or
liability under the Notes. If there shall be more than one Borrower, each Borrower shall be jointly and severally liable hereunder. Upon
assignment or transfer of the Notes by any Secured Party, such assignee shall automatically become a Secured Party hereunder.


 


Security Agreement

16) Survival
of Representations and Warranties. All representations and warranties of Borrower and all terms, provisions, conditions and agreements
to be performed by Borrower contained herein, and in any other agreement, document and instrument executed by Borrower concurrently herewith,
shall be true and satisfied at the time of the execution of this Security Agreement, and shall survive the closing hereof and the execution
and delivery of this Security Agreement.


 


17) Counterparts,
Effect of Facsimile, Emailed and Photocopied Signatures. This Agreement and any signed agreement or instrument entered into in
connection with this Agreement, and any amendments hereto or thereto, may be executed in one or more counterparts, all of which shall
constitute one and the same instrument. Any such counterpart, to the extent delivered by means of a facsimile machine or by .pdf, .tif,
..gif, .jpeg or similar attachment to electronic mail (including email) or as an electronic download (any such delivery, an “Electronic
Delivery”) shall be treated in all manner and respects as an original executed counterpart and shall be considered to have
the same binding legal effect as if it were the original signed version thereof delivered in person. No party shall raise the use of Electronic
Delivery to deliver a signature or the fact that any signature or agreement or instrument was transmitted or communicated through the
use of Electronic Delivery as a defense to the formation of a contract, and each such party forever waives any such defense, except to
the extent such defense relates to lack of authenticity.


 


18) Governing
Law and Jurisdiction. This Agreement shall be governed by, enforced, and construed under and in accordance with the laws of the
United States of America and, with respect to the matters of state law, with the laws of the State of Minnesota without giving effect
to principles of conflicts of law thereunder. Each of the parties hereby: (a) irrevocably submits to the non-exclusive personal jurisdiction
of any Minnesota court, over any claim arising out of or relating to this Agreement and irrevocably agrees that all such claims may be
heard and determined in such Minnesota court; and (b) irrevocably waives, to the fullest extent permitted by applicable law, any objection
it may now or hereafter have to the laying of venue in any proceeding brought in a Minnesota court.

ARISING IN ANY WAY FROM THIS AGREEMENT OR THE TRANSACTIONS CONTEMPLATED HEREIN.


 


21) Severability.
If any term or other provision of this Agreement is determined to be invalid, illegal or incapable of being enforced by any rule or law,

Upon such determination that any term or other provision is invalid, illegal or incapable of being enforced, the parties hereto shall
negotiate in good faith to modify this Agreement so as to effect the original intent of the parties as closely as possible in an acceptable
manner to the end that transactions contemplated hereby are fulfilled to the extent possible.

money damages in the event of any such failure and (c) that in the event of any such failure, the other party may be entitled to (i) specific
performance, injunctive and other equitable relief to compel the breaching party to comply with its obligations in accordance with the

and has obtained the advice of its own legal, tax and business advisors before executing this Agreement; (d) said party has acted voluntarily

Warrant #______________________  


 


COMMON STOCK PURCHASE WARRANT


 


EPIEN MEDICAL, INC.


 


Initial Exercise Date: (date)


 


THIS COMMON STOCK PURCHASE WARRANT (the
“Warrant”) certifies that, for value received, ________________________________ or its assigns (the
“Holder”) is entitled, upon the terms and subject to the limitations on exercise and the conditions hereinafter set
forth, at any time on or after the Vesting Date (the “Initial Exercise Date”) and on or prior to 5:00 p.m. (New
York City time) on the fifth anniversary of the Vesting Date (the “Termination Date”) but not thereafter, to
subscribe for and purchase from Epien Medical, Inc., a Minnesota corporation (the “Company”), up to the Total
Warrant Shares (defined below)(as subject to adjustment hereunder, as applicable, the “Warrant Shares”) of Common
Stock. The purchase price of one share of Common Stock under this Warrant shall be equal to the Exercise Price, as defined in
Section 2(b). The “Total Warrant Shares” equals (a) the Note Principal, multiplied by (b) 80%, and divided by (c)
(i) 0.90 multiplied by (ii) the Public Offering Price (defined below), rounded up to the nearest whole number. For example, if the
Note Principal was $25,000 and the Public Offering Price was $2.50, the Total Warrant Shares would be 8,888 = ($25,000 x 0.80)
÷ (0.9 x $2.50), rounded up to the nearest whole share. The “Vesting Date” shall be the date the Qualified
Offering closes, as defined below. “Note Principal” means the principal amount of the Senior Secured Convertible
Notes acquired by the Holder pursuant to the Subscription Agreement.


 


Section 1. Definitions. Capitalized terms used and
not otherwise defined herein shall have the meanings set forth in that certain Subscription Agreement (the
“Subscription Agreement”), dated August 13, 2021, among the Company and the purchasers signatory thereto.

 Section 2. Exercise.


 


a) Exercise of Warrant. Exercise of the purchase rights
represented by this Warrant may be made, in whole or in part, at any time or times on or after the Initial Exercise Date and on or
before the Termination Date by delivery to the Company of a duly executed facsimile copy or PDF copy submitted by e-mail (or e-mail
attachment) of the Notice of Exercise in the form annexed hereto (the “Notice of Exercise”). Within the two (2)
Trading Days 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’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) Business Day of receipt of such notice. The Holder and any
assignee, by acceptance of this Warrant, acknowledge and agree that, by reason of the provisions of this paragraph, following the
purchase of a portion of the Warrant Shares hereunder, the number of Warrant Shares available for purchase hereunder at any given
time may be less than the amount stated on the face hereof.


 


b) Exercise Price. The exercise price per share of Common
Stock under this Warrant shall be Ninety Percent (90%) of the Public Offering Price, subject to adjustment hereunder (the
“Exercise Price”). “Public Offering Price” means the actual or implied price per share of
Common Stock paid by the purchasers of the Qualified Offering Securities sold in the Qualified Financing, as reasonably determined
by the board of directors of the Company. “Qualified Financing” means the closing of the Company’s first
sale of its Common Stock to the public after the date of this Warrant (including as part of a unit or in the form of, or as part of,
a convertible security), in an offering underwritten by an investment banking firm, pursuant to an effective registration statement
under the Securities Act, which results in the Common Stock being listed on a national securities exchange or NASDAQ, or quoted on
the OTCQB or OTCQX market. “Qualified Offering Securities” means the equity securities issued by the Company in
the Qualified Financing. For example, if the Public Offering Price was $2.50, the Exercise Price would be $2.25 = 0.9 x $2.50.

c) Cashless
Exercise. Notwithstanding anything contained herein to the contrary, if at the time of exercise hereof a registration statement under
the Securities Act is not effective (or the prospectus contained therein is not available for use) for the sale of all of the Warrant
Shares, then the Holder may, in its sole discretion, exercise this Warrant, in whole or in part, at such time by means of a “cashless
exercise” in which the Holder shall be entitled to receive a number of Warrant Shares equal to the quotient obtained by dividing
[(A-B) (X)] by (A), where:


 


		(A) = 	as applicable: (i) the Closing Sales Price on the Trading
Day immediately preceding the date of the applicable Notice of Exercise if such Notice of Exercise is (1) both executed and delivered
pursuant to Section 2(a) hereof on a day that is not a Trading Day or (2) both executed and delivered pursuant to Section 2(a) hereof
on a Trading Day prior to the opening of “regular trading hours” (as defined in Rule 600(b)(68) of Regulation NMS promulgated
under the federal securities laws) on such Trading Day, or (ii) the Closing Sales Price on the date of the applicable Notice of Exercise
if the date of such Notice of Exercise is a Trading Day and such Notice of Exercise is executed and delivered pursuant to Section 2(a)
hereof during “regular trading hours” or after the close of “regular trading hours” on such Trading Day;



 


		(B) = 	the Exercise Price of this Warrant, as adjusted hereunder;
and



 


		(X) = 	the number of Warrant Shares that would be issuable upon
exercise of this Warrant in accordance with the terms of this Warrant if such exercise were by means of a cash exercise rather than a
cashless exercise.



 


If Warrant Shares are issued in such a cashless
exercise, the parties acknowledge and agree that in accordance with Section 3(a)(9) of the Securities Act, the Warrant Shares shall take
on the characteristics of the Warrants being exercised, and the holding period of the Warrant Shares being issued may be tacked on to
the holding period of this Warrant. The Company agrees not to take any position contrary to this Section 2(c).


 


“Closing Sales Price” means
the last sales price of the Common Stock on the Principal Market as reported by NASDAQ.com (or a comparable reporting service of national
reputation selected by the Corporation and reasonably acceptable to a Majority In Interest of the Holders if NASDAQ.com is not then reporting
closing sales prices the Common Stock) (collectively, “NASDAQ.com”), or if the foregoing does not apply, the last reported
sales price of such security on a national exchange or in the over-the-counter market on the electronic bulletin board for such security
as reported by NASDAQ.com, or, if no such price is reported for such security by NASDAQ.com, the average of the bid prices of all market
makers for such security as reported in the “pink sheets” by the National Quotation Bureau, Inc., in each case for such date
or, if such date was not a Trading Day for such security, on the next preceding date that was a Trading Day. If the Closing Sales Price
cannot be calculated for such security as of either of such dates on any of the foregoing bases, the Closing Sales Price of such security
on such date shall be the fair market value as reasonably determined by an investment banking firm
selected by the Corporation and reasonably acceptable to a Majority In Interest of the Holders, with the costs of such appraisal to be
borne by the Corporation.


 


Warrant #


 




    3


     


    

 


“Bid Price” means, for any date,
the price determined by the first of the following clauses that applies: (a) if the Common Stock is then listed or quoted on a Trading
Market, the bid price of the Common Stock for the time in question (or the nearest preceding date) on the Trading Market on which the
Common Stock is then listed or quoted as reported by Bloomberg L.P. (based on a Trading Day from 9:30 a.m. (New York City time) to 4:02
p.m. (New York City time)), (b) if OTC is not a Trading Market, the volume weighted average price of the Common Stock for such date (or
the nearest preceding date) on OTC as applicable, (c) if the Common Stock is not then listed or quoted for trading on OTC and if prices
for the Common Stock are then reported on The OTC Pink Market (or a similar organization or agency succeeding to its functions of reporting
prices), the most recent bid price per share of the Common Stock so reported, or (d) in all other cases, the fair market value of a share
of Common Stock as determined by an independent appraiser selected in good faith by the Purchasers of a majority in interest of the Securities
then outstanding and reasonably acceptable to the Company, the fees and expenses of which shall be paid by the Company.


 


“Trading Day” means any day
on which the Common Stock is traded on the Trading Market, provided that “Trading Day” shall not include any day on
which the Common Stock is scheduled to trade on the Trading Market for less than 4.5 hours or any day that the Common Stock is suspended
from trading during the final hour of trading on the Trading Market (or if the Trading Market does not designate in advance the closing
time of trading on the Trading Market, then during the hour ending at 4:00:00 p.m., New York City time) unless such day is otherwise designated
as a Trading Day in writing by the Investor.


 


“Trading Market” means any of
the following markets or exchanges on which the Common Stock is listed or quoted for trading on the date in question: the NYSE American,
the Nasdaq Capital Market, the Nasdaq Global Market, the Nasdaq Global Select Market, the New York Stock Exchange, or the OTCQB or OTCQX
(or any successors to any of the foregoing).


 


d) Mechanics of Exercise.


 


i. Delivery
of Warrant Shares Upon Exercise. The Company shall cause the Warrant Shares purchased hereunder to be transmitted by its transfer
agent (the “Transfer Agent”) to the Holder by crediting the account of the Holder’s or its designee’s balance
account with The Depository Trust Company through its Deposit or Withdrawal at Custodian system (“DWAC”) if the Company
is then a participant in such system and either (A) there is an effective registration statement permitting the issuance of the Warrant
Shares to or resale of the Warrant Shares by the Holder or (B) the Warrant Shares are eligible for resale
by the Holder without volume or manner-of-sale limitations pursuant to Rule 144 (assuming cashless exercise of the Warrants), and otherwise
by physical delivery of a certificate, registered in the Company’s share register in the name of the Holder or its designee, for
the number of Warrant Shares to which the Holder is entitled pursuant to such exercise to the address specified by the Holder in the Notice
of Exercise by the date that is the earliest of (i) two (2) Trading Days after the delivery to the Company of the Notice of Exercise and
(ii) one (1) Trading Day after delivery of the aggregate Exercise Price to the Company (such date, the “Warrant Share Delivery
Date”). Upon delivery of the Notice of Exercise, the Holder shall be deemed for all corporate purposes to have become the holder
of record of the Warrant Shares with respect to which this Warrant has been exercised, irrespective of the date of delivery of the Warrant
Shares, provided that payment of the aggregate Exercise Price (other than in the case of a cashless exercise) is received within two (2)
Trading Days following delivery of the Notice of Exercise.


 


ii. Delivery
of New Warrants Upon Exercise. If this Warrant shall have been exercised in part, the Company shall, at the request of a Holder and
upon surrender of this Warrant certificate, at the time of delivery of the Warrant Shares, deliver to the Holder a new Warrant evidencing
the rights of the Holder to purchase the unpurchased Warrant Shares called for by this Warrant, which new Warrant shall in all other respects
be identical with this Warrant.


 


iii. No
Fractional Shares. No fractional shares shall be issued upon the exercise of this Warrant. As to any fraction of a share which the
Holder would otherwise be entitled to purchase upon such exercise, the Company shall, at its election, either pay a cash adjustment in
respect of such final fraction in an amount equal to such fraction multiplied by the Exercise Price or round up to the next whole share.


 


iv. Charges,
Taxes and Expenses. Issuance of Warrant Shares shall be made without charge to the Holder for any issue or transfer tax or other incidental
expense in respect of the issuance of such Warrant Shares, all of which taxes and expenses shall be paid by the Company, and such Warrant
Shares shall be issued in the name of the Holder or in such name or names as may be directed by the Holder; provided, however,
that, in the event that Warrant Shares are to be issued in a name other than the name of the Holder, this Warrant when surrendered for
exercise shall be accompanied by the Assignment Form attached hereto duly executed by the Holder and the Company may require, as a condition
thereto, the payment of a sum sufficient to reimburse it for any transfer tax incidental thereto. The Company shall pay all Transfer Agent
fees required for same-day processing of any Notice of Exercise and all fees to the Depository Trust Company (or another established clearing corporation
performing similar functions) required for same-day electronic delivery of the Warrant Shares.

v. Closing
of Books. The Company will not close its stockholder books or records in any manner which prevents the timely exercise of this Warrant,
pursuant to the terms hereof.


 


e) Holder’s
Exercise Limitations. The Company shall not effect any exercise of this Warrant, and a Holder shall not have the right to exercise
any portion of this Warrant, pursuant to Section 2 or otherwise, to the extent that after giving effect to such issuance after exercise
as set forth on the applicable Notice of Exercise, the Holder (together with the Holder’s Affiliates, and any other Persons acting
as a group together with the Holder or any of the Holder’s Affiliates (such Persons, “Attribution Parties”)),
would beneficially own in excess of the Beneficial Ownership Limitation (as defined below). 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, nonexercised portion of this Warrant
beneficially owned by the Holder or any of its Affiliates or Attribution Parties and (ii) exercise or conversion of the unexercised or
nonconverted portion of any other securities of the Company (including, without limitation, any other Common Stock equivalents) subject
to a limitation on conversion or exercise analogous to the limitation contained herein beneficially owned by the Holder or any of its
Affiliates or Attribution Parties. Except as set forth in the preceding sentence, for purposes of this Section 2(e), beneficial ownership
shall be calculated in accordance with Section 13(d) of the Exchange Act and the rules and regulations promulgated thereunder, it being
acknowledged by the Holder that the Company is not representing to the Holder that such calculation is in compliance with Section 13(d)
of the Exchange Act and the Holder is solely responsible for any schedules required to be filed in accordance therewith. To the extent
that the limitation contained in this Section 2(e) 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’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’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. 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. 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 “Beneficial Ownership Limitation” shall be 4.99% 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 limitations contained in this paragraph shall apply to a successor holder of this Warrant.

Section 3. Certain Adjustments.


 


a) Stock
Dividends and Splits. If the Company, at any time while this Warrant is outstanding: (i) pays a stock dividend or otherwise makes
a distribution or distributions on shares of its Common Stock or any other equity or equity equivalent securities payable in shares of
Common Stock (which, for avoidance of doubt, shall not include any shares of Common Stock issued by the Company upon exercise of this
Warrant), (ii) subdivides outstanding shares of Common Stock into a larger number of shares, (iii) combines (including by way of reverse
stock split) outstanding shares of Common Stock into a smaller number of shares, or (iv) issues by reclassification of shares of the Common
Stock any shares of capital stock of the Company, then in each case the Exercise Price shall be multiplied by a fraction of which the
numerator shall be the number of shares of Common Stock (excluding treasury shares, if any) outstanding immediately before such event
and of which the denominator shall be the number of shares of Common Stock outstanding immediately after such event, and the number of
shares issuable upon exercise of this Warrant shall be proportionately adjusted such that the aggregate Exercise Price of this Warrant
shall remain unchanged. Any adjustment made pursuant to this Section 3(a) shall become effective immediately after the record date for
the determination of stockholders entitled to receive such dividend or distribution and shall become effective immediately after the effective
date in the case of a subdivision, combination or re-classification.


 


b) Calculations.
All calculations under this Section 3 shall be made to the nearest cent or the nearest 1/100th of a share, as the case may be. For purposes
of this Section 3, the number of shares of Common Stock deemed to be issued and outstanding as of a given date shall be the sum of the
number of shares of Common Stock (excluding treasury shares, if any) issued and outstanding.


 


c) Notice
to Holder.


 


i. Adjustment
to Exercise Price. Whenever the Exercise Price is adjusted pursuant to any provision of this Section 3, the Company shall promptly
deliver to the Holder by facsimile or email a notice setting forth the Exercise Price after such adjustment and any resulting adjustment
to the number of Warrant Shares and setting forth a brief statement of the facts requiring such adjustment.


 


ii. Notice
to Allow Exercise by Holder. If (A) the Company shall declare a dividend (or any other distribution in whatever form) on the Common
Stock, (B) the Company shall declare a special nonrecurring cash dividend on or a redemption of the Common Stock, (C) the Company shall
authorize the granting to all holders of the Common Stock rights or warrants to subscribe for or purchase any shares of capital stock
of any class or of any rights, (D) the approval of any stockholders of the Company shall be required in connection with any reclassification
of the Common Stock, any consolidation or merger to which the Company (and all of its Subsidiaries, taken as a whole) is a party, any
sale or transfer of all or substantially all of the assets of the Company, or any compulsory share exchange whereby the Common Stock is
converted into other securities, cash or property, or (E) the Company shall authorize the voluntary or involuntary dissolution, liquidation
or winding up of the affairs of the Company, then, in each case, the Company shall cause to be delivered by facsimile or email to the
Holder at its last facsimile number or email address as it shall appear upon the Warrant Register of the Company, at least 20 calendar
days prior to the applicable record or effective date hereinafter specified, a notice stating (x) the date on which a record is to be
taken for the purpose of such dividend, distribution, redemption, rights or warrants, or if a record is not to be taken, the date as of
which the holders of the Common Stock of record to be entitled to such dividend, distributions, redemption, rights or warrants are to
be determined or (y) the date on which such reclassification, consolidation, merger, sale, transfer or share exchange is expected to become
effective or close, and the date as of which it is expected that holders of the Common Stock of record shall be entitled to exchange their
shares of the Common Stock for securities, cash or other property deliverable upon such reclassification, consolidation, merger, sale,
transfer or share exchange; provided that the failure to deliver such notice or any defect therein or in the delivery thereof shall not
affect the validity of the corporate action required to be specified in such notice. To the extent that any notice provided in this Warrant
constitutes, or contains, material, non-public information regarding the Company or any of the Subsidiaries, the Company shall simultaneously
file such notice with the Securiteis and Exchange Commission pursuant to a Current Report on Form 8-K (to the extent the Company is a
reporting company at the time of such event). The Holder shall remain entitled to exercise this Warrant during the period commencing on
the date of such notice to the effective date of the event triggering such notice except as may otherwise be expressly set forth
herein.

d) Voluntary
Adjustment By Company. Subject to the rules and regulations of the Trading Market, the Company may at any time during the term of
this Warrant, subject to the prior written consent of the Holder, and the terms of the Subscription Agreement, reduce the then current
Exercise Price to any amount and for any period of time deemed appropriate by the board of directors of the Company.


 


Section 4. Transfer of Warrant.


 


a) Transferability.
Subject to compliance with any applicable securities laws and the conditions set forth in Section 4(d) hereof and to the provisions of
Section 4.1 of the Subscription Agreement, this Warrant and all rights hereunder (including, without limitation, any registration rights)
are transferable, in whole or in part, upon surrender of this Warrant at the principal office of the Company or its designated agent,
together with a written assignment of this Warrant substantially in the form attached hereto duly executed by the Holder or its agent
or attorney and funds sufficient to pay any transfer taxes payable upon the making of such transfer. Upon such surrender and, if required,
such payment, the Company shall execute and deliver a new Warrant or Warrants in the name of the assignee or assignees, as applicable,
and in the denomination or denominations specified in such instrument of assignment, and shall issue to the assignor a new Warrant evidencing
the portion of this Warrant not so assigned, and this Warrant shall promptly be cancelled. Notwithstanding anything herein to the contrary,
the Holder shall not be required to physically surrender this Warrant to the Company unless the Holder has assigned this Warrant in full,
in which case, the Holder shall surrender this Warrant to the Company within three (3) Trading Days of the date on which the Holder delivers
an assignment form to the Company assigning this Warrant in full. The Warrant, if properly assigned in accordance herewith, may be exercised
by a new holder for the purchase of Warrant Shares without having a new Warrant issued.


 


b) New
Warrants. This Warrant may be divided or combined with other Warrants upon presentation hereof at the aforesaid office of the Company,
together with a written notice specifying the names and denominations in which new Warrants are to be issued, signed by the Holder or
its agent or attorney. Subject to compliance with Section 4(a), as to any transfer which may be involved in such division or combination,
the Company shall execute and deliver a new Warrant or Warrants in exchange for the Warrant or Warrants to be divided or combined in accordance
with such notice. All Warrants issued on transfers or exchanges shall be dated the Initial Exercise Date and shall be identical with this
Warrant except as to the number of Warrant Shares issuable pursuant thereto.


 


c) Warrant
Register. The Company shall register this Warrant, upon records to be maintained by the Company for that purpose (the “Warrant
Register”), in the name of the record Holder hereof from time to time. The Company may deem and treat the registered Holder
of this Warrant as the absolute owner hereof for the purpose of any exercise hereof or any distribution to the Holder, and for all other
purposes, absent actual notice to the contrary

d) Transfer
Restrictions. If, at the time of the surrender of this Warrant in connection with any transfer of this Warrant, the transfer of this
Warrant shall not be either (i) registered pursuant to an effective registration statement under the Securities Act and under applicable
state securities or blue sky laws or (ii) eligible for resale without volume or manner-of-sale restrictions or current public information
requirements pursuant to Rule 144, the Company may require, as a condition of allowing such transfer, that the Holder or transferee of
this Warrant, as the case may be, comply with, and make the same representations as, the Purchasers in the Subscription Agreement, including,
but not limited to Section 2 of the Subscription Agreement.


 


e) Representation
by the Holder. The Holder, by the acceptance hereof, represents and warrants that it is acquiring this Warrant and, upon any exercise
hereof, will acquire the Warrant Shares issuable upon such exercise, for its own account and not with a view to or for distributing or
reselling such Warrant Shares or any part thereof in violation of the Securities Act or any applicable state securities law, except pursuant
to sales registered or exempted under the Securities Act.


 


Section 5. Miscellaneous.


 


a) No
Rights as Stockholder Until Exercise; No Settlement in Cash. This Warrant does not entitle the Holder to any voting rights, dividends
or other rights as a stockholder of the Company prior to the exercise hereof as set forth in Section 2(d)(i), except as expressly set
forth in Section 3. Without limiting any rights of a Holder to receive Warrant Shares on a “cashless exercise” pursuant to
Section 2(c) herein, in no event shall the Company be required to net cash settle an exercise of this Warrant.


 


b) Loss,
Theft, Destruction or Mutilation of Warrant. The Company covenants that upon receipt by the Company of evidence reasonably satisfactory
to it of the loss, theft, destruction or mutilation of this Warrant or any stock certificate relating to the Warrant Shares, and in case
of loss, theft or destruction, of indemnity or security reasonably satisfactory to it (which, in the case of the Warrant, shall not include
the posting of any bond), and upon surrender and cancellation of such Warrant or stock certificate, if mutilated, the Company will make
and deliver a new Warrant or stock certificate of like tenor and dated as of such cancellation, in lieu of such Warrant or stock certificate.


 


c) Saturdays,
Sundays, Holidays, etc. If the last or appointed day for the taking of any action or the expiration of any right required or granted
herein shall not be a Business Day, then such action may be taken or such right may be exercised on the next succeeding Business Day.

d) Authorized
Shares.


 


The Company covenants that, during the period the
Warrant is outstanding, it will reserve from its authorized and unissued Common Stock a sufficient number of shares to provide for the
issuance of the Warrant Shares upon the exercise of any purchase rights under this Warrant. The Company further covenants that its issuance
of this Warrant shall constitute full authority to its officers who are charged with the duty of issuing the necessary Warrant Shares
upon the exercise of the purchase rights under this Warrant. The Company will take all such reasonable action as may be necessary to assure
that such Warrant Shares may be issued as provided herein without violation of any applicable law or regulation, or of any requirements
of the Trading Market upon which the Common Stock may be listed. The Company covenants that all Warrant Shares which may be issued upon
the exercise of the purchase rights represented by this Warrant will, upon exercise of the purchase rights represented by this Warrant
and payment for such Warrant Shares in accordance herewith, be duly authorized, validly issued, fully paid and nonassessable and free
from all taxes, liens and charges created by the Company in respect of the issue thereof (other than taxes in respect of any transfer
occurring contemporaneously with such issue).


 


Except and to the extent as waived or consented
to by the Holder, the Company shall not by any action, including, without limitation, amending its certificate of incorporation or through
any reorganization, transfer of assets, consolidation, merger, dissolution, issue or sale of securities or any other voluntary action,
avoid or seek to avoid the observance or performance of any of the terms of this Warrant, but will at all times in good faith assist in
the carrying out of all such terms and in the taking of all such actions as may be necessary or appropriate to protect the rights of Holder
as set forth in this Warrant against impairment. Without limiting the generality of the foregoing, the Company will (i) not increase the
par value of any Warrant Shares above the amount payable therefor upon such exercise immediately prior to such increase in par value,
(ii) take all such action as may be necessary or appropriate in order that the Company may validly and legally issue fully paid and nonassessable
Warrant Shares upon the exercise of this Warrant and (iii) use commercially reasonable efforts to obtain all such authorizations, exemptions
or consents from any public regulatory body having jurisdiction thereof, as may be, necessary to enable the Company to perform its obligations
under this Warrant.


 


Before taking any action which would result in
an adjustment in the number of Warrant Shares for which this Warrant is exercisable or in the Exercise Price, the Company shall obtain
all such authorizations or exemptions thereof, or consents thereto, as may be necessary from any public regulatory body or bodies having
jurisdiction thereof.


 


e) Jurisdiction.
All questions concerning the construction, validity, enforcement and interpretation of this Warrant shall be determined in accordance
with the provisions of the Subscription Agreement.


 


Warrant #


 




    9


     


    

 


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


 


g) Nonwaiver
and Expenses. No course of dealing or any delay or failure to exercise any right hereunder on the part of Holder shall operate as
a waiver of such right or otherwise prejudice the Holder’s rights, powers or remedies. Without limiting any other provision of this
Warrant or the Subscription Agreement, if the Company willfully and knowingly fails to comply with any provision of this Warrant, which
results in any material damages to the Holder, the Company shall pay to the Holder such amounts as shall be sufficient to cover any costs
and expenses including, but not limited to, reasonable attorneys’ fees, including those of appellate proceedings, incurred by the
Holder in collecting any amounts due pursuant hereto or in otherwise enforcing any of its rights, powers or remedies hereunder.


 


h) Notices.
Any notice, request or other document required or permitted to be given or delivered to the Holder by the Company shall be delivered in
accordance with the notice provisions of the Subscription Agreement.


 


i) Limitation
of Liability. No provision hereof, in the absence of any affirmative action by the Holder to exercise this Warrant to purchase Warrant
Shares, and no enumeration herein of the rights or privileges of the Holder, shall give rise to any liability of the Holder for the purchase
price of any Common Stock or as a stockholder of the Company, whether such liability is asserted by the Company or by creditors of the
Company.


 


j) Successors
and Assigns. Subject to applicable securities laws, this Warrant and the rights and obligations evidenced hereby shall inure to the
benefit of and be binding upon the successors and permitted assigns of the Company and the successors and permitted assigns of Holder.
The provisions of this Warrant are intended to be for the benefit of any Holder from time to time of this Warrant and shall be enforceable
by the Holder or holder of Warrant Shares.


 


k) Amendment.
This Warrant may not be modified or amended or the provisions hereof waived without the written consent of the Company and the Holder
of this Warrant.


 


l) Severability.
Wherever possible, each provision of this Warrant shall be interpreted in such manner as to be effective and valid under applicable law,
but if any provision of this 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 provisions or the remaining provisions of this Warrant.


 


m) Headings.
The headings used in this Warrant are for the convenience of reference only and shall not, for any purpose, be deemed a part of this Warrant.

THIS COMMON STOCK PURCHASE WARRANT (the “Warrant”)
certifies that, for value received, (name), or its assigns (the “Holder”) is entitled, upon the terms and subject
to the limitations on exercise and the conditions hereinafter set forth, at any time on or after the Vesting Date (the “Initial
Exercise Date”) and on or prior to 5:00 p.m. (New York City time) on the fifth anniversary of the Vesting Date (the “Termination
Date”) but not thereafter, to subscribe for and purchase from Epien Medical, Inc., a Minnesota corporation (the “Company”),
up to the Total Warrant Shares (defined below) (as subject to adjustment hereunder, as applicable, the “Warrant Shares”)
of Common Stock. The purchase price of one share of Common Stock under this Warrant shall be equal to the Exercise Price, as defined in
Section 2(b). The “Total Warrant Shares” equals (a) the total amount of Notes sold under the Offering, multiplied by
(b) 20%, and divided by (c) (i) 0.90 multiplied by (ii) the Public Offering Price (defined below), rounded up to the nearest whole number.
For example, if the total amount of Notes sold in the Offering was $1,775,000 and the Public Offering Price was $2.50, the Total Warrant
Shares would be 157,778 = ($1,775,000 x 0.20) ÷ (0.9 x $2.50), rounded up to the nearest whole share. The “Vesting Date”
shall be the date the Qualified Offering (as defined below) closes. “Note Principal” means the principal amount of
the Senior Secured Convertible Notes acquired by the Holder pursuant to the Subscription Agreement.

Section 1. Definitions. Capitalized
terms used and not otherwise defined herein shall have the meanings set forth in that certain Subscription Agreement (the “Subscription
Agreement”), dated (date), among the Company and the Purchasers signatory thereto.


 


Section 2. Exercise.


 


a) Exercise
of Warrant. Exercise of the purchase rights represented by this Warrant may be made, in whole or in part, at any time or times on
or after the Initial Exercise Date and on or before the Termination Date by delivery to the Company of a duly executed facsimile copy
or PDF copy submitted by e-mail (or e-mail attachment) of the Notice of Exercise in the form annexed hereto (the “Notice of Exercise”).
Within the two (2) Trading Days 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’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. Upon partial exercise, the Company shall promptly issue an amended Warrant representing the remaining number of Shares purchasable
thereunder. All other terms and conditions of such amended Warrant shall be identical to those contained herein. 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.


 


b) Exercise
Price. The exercise price per share of Common Stock under this Warrant shall be Ninety Percent (90%) of the Public Offering Price,
subject to adjustment hereunder (the “Exercise Price”). “Public Offering Price” means the actual
or implied price per share of Common Stock paid by the purchasers of the Qualified Offering Securities sold in the Qualified Financing,
as reasonably determined by the board of directors of the Company. “Qualified Financing” means the closing of the Company’s
first sale of its Common Stock to the public after the date of this Warrant (including as part of a unit or in the form of, or as part
of, a convertible security), in an offering underwritten by an investment banking firm, pursuant to an effective registration statement
under the Securities Act, which results in the Common Stock being listed on a national securities exchange or NASDAQ, or quoted on the
OTCQB or OTCQX market. “Qualified Offering Securities” means the equity securities issued by the Company in the Qualified
Financing. For example, if the Public Offering Price was $2.50, the Exercise Price would be $2.25 = 0.9 x $2.50.


 


c) Cashless
Exercise. Notwithstanding anything contained herein to the contrary, if at the time of exercise hereof, a registration statement under
the Securities Act is not effective (or the prospectus contained therein is not available for use) for the sale of all of the Warrant
Shares, then the Holder may, in its sole discretion, exercise this Warrant, in whole or in part, at such time by means of a “cashless
exercise” in which the Holder


 


Warrant #


 




    2


     


    

 


shall be entitled to receive a number of Warrant Shares equal to the
quotient obtained by dividing [(A-B)*(X)] by (A), where:


 


		(A) =	as applicable: (i) the Closing Sales Price on the Trading Day immediately preceding the date of the applicable Notice of Exercise
if such Notice of Exercise is (1) both executed and delivered pursuant to Section 2(a) hereof on a day that is not a Trading Day or (2)
both executed and delivered pursuant to Section 2(a) hereof on a Trading Day prior to the opening of “regular trading hours”
(as defined in Rule 600(b)(68) of Regulation NMS promulgated under the federal securities laws) on such Trading Day, or (ii) the Closing
Sales Price on the date of the applicable Notice of Exercise if the date of such Notice of Exercise is a Trading Day and such Notice of
Exercise is executed and delivered pursuant to Section 2(a) hereof during “regular trading hours” or after the close of “regular
trading hours” on such Trading Day;



 


		(B) = 	the Exercise Price of this Warrant, as adjusted hereunder; and



 


		(X) = 	the number of Warrant Shares that would be issuable upon
exercise of this Warrant in accordance with the terms of this Warrant if such exercise were by means of a cash exercise rather than a
cashless exercise.



 


If Warrant Shares are issued in such a cashless
exercise, the parties acknowledge and agree that in accordance with Section 3(a)(9) of the Securities Act, the Warrant Shares shall take
on the characteristics of the Warrants being exercised, and the holding period of the Warrant Shares being issued may be tacked on to
the holding period of this Warrant. The Company agrees not to take any position contrary to this Section 2(c).


 


“Closing Sales Price” means
the last sales price of the Common Stock on the Principal Market as reported by NASDAQ.com (or a comparable reporting service of
national reputation selected by the Corporation and reasonably acceptable to a Majority In Interest of the Holders if NASDAQ.com
is not then reporting closing sales prices the Common Stock) (collectively, “NASDAQ.com”), or if the foregoing does
not apply, the last reported sales price of such security on a national exchange or in the over-the-counter market on the electronic bulletin
board for such security as reported by NASDAQ.com, or, if no such price is reported for such security by NASDAQ.com, the
average of the bid prices of all market makers for such security as reported by The OTC Pink Market (or a similar organization or agency
succeeding to its functions of reporting prices), in each case for such date or, if such date was not a Trading Day for such security,
on the next preceding date that was a Trading Day. If the Closing Sales Price cannot be calculated for such security as of either of such
dates on any of the foregoing bases, the Closing Sales Price of such security on such date shall be the fair market value as reasonably
determined by an investment banking firm selected by the Corporation and reasonably acceptable to a Majority In Interest of the Holders,
with the costs of such appraisal to be borne by the Corporation.


 


Warrant #

“Bid Price” means, for any date,
the price determined by the first of the following clauses that applies: (a) if the Common Stock is then listed or quoted on a Trading
Market, the bid price of the Common Stock for the time in question (or the nearest preceding date) on the Trading Market on which the
Common Stock is then listed or quoted as reported by Bloomberg L.P. (based on a Trading Day from 9:30 a.m. (New York City time) to 4:02
p.m. (New York City time)), (b) if OTC is not a Trading Market, the volume weighted average price of the Common Stock for such date (or
the nearest preceding date) on OTC as applicable, (c) if the Common Stock is not then listed or quoted for trading on OTC and if prices
for the Common Stock are then reported on The OTC Pink Market (or a similar organization or agency succeeding to its functions of reporting
prices), the most recent bid price per share of the Common Stock so reported, or (d) in all other cases, the fair market value of a share
of Common Stock as determined by an independent appraiser selected in good faith by the Purchasers of a majority in interest of the Securities
then outstanding and reasonably acceptable to the Company, the fees and expenses of which shall be paid by the Company.


 


“Trading Day” means any day
on which the Common Stock is traded on the Trading Market, provided that “Trading Day” shall not include any day on
which the Common Stock is scheduled to trade on the Trading Market for less than 4.5 hours or any day that the Common Stock is suspended
from trading during the final hour of trading on the Trading Market (or if the Trading Market does not designate in advance the closing
time of trading on the Trading Market, then during the hour ending at 4:00:00 p.m., New York City time) unless such day is otherwise designated
as a Trading Day in writing by the Investor.


 


“Trading Market” means any of
the following markets or exchanges on which the Common Stock is listed or quoted for trading on the date in question: the NYSE American,
the Nasdaq Capital Market, the Nasdaq Global Market, the Nasdaq Global Select Market, the New York Stock Exchange, or the OTCQB or OTCQX
(or any successors to any of the foregoing).


 


d) Mechanics of Exercise.


 


i. Delivery
of Warrant Shares Upon Exercise. The Company shall cause the Warrant Shares purchased hereunder to be transmitted by its transfer
agent (the “Transfer Agent”) to the Holder by crediting the account of the Holder’s or its designee’s balance
account with The Depository Trust Company through its Deposit or Withdrawal at Custodian system (“DWAC”) if the Company
is then a participant in such system and either (A) there is an effective registration statement permitting the issuance of the Warrant
Shares to or resale of the Warrant Shares by the Holder or (B) the Warrant Shares are eligible for resale by the Holder without volume
or manner-of-sale limitations pursuant to Rule 144 (assuming cashless exercise of the Warrants), and otherwise by physical delivery of
a certificate, registered in the Company’s share register in the name of the Holder or its designee, for the number
of Warrant Shares to which the Holder is entitled pursuant to such exercise to the address specified by the Holder in the Notice of Exercise
by the date that is the earliest of (i) two (2) Trading Days after the delivery to the Company of the Notice of Exercise and (ii) one
(1) Trading Day after delivery of the aggregate Exercise Price to the Company (such date, the “Warrant Share Delivery Date”).
Upon delivery of the Notice of Exercise, the Holder shall be deemed for all corporate purposes to have become the holder of record of
the Warrant Shares with respect to which this Warrant has been exercised, irrespective of the date of delivery of the Warrant Shares,
provided that payment of the aggregate Exercise Price (other than in the case of a cashless exercise) is received within two (2) Trading
Days following delivery of the Notice of Exercise.

ii. Delivery
of New Warrants Upon Exercise. If this Warrant shall have been exercised in part, the Company shall, at the request of a Holder and
upon surrender of this Warrant certificate, at the time of delivery of the Warrant Shares, deliver to the Holder a new Warrant evidencing
the rights of the Holder to purchase the unpurchased Warrant Shares called for by this Warrant, which new Warrant shall in all other respects
be identical with this Warrant.


 


iii. No
Fractional Shares. No fractional shares shall be issued upon the exercise of this Warrant. As to any fraction of a share which the
Holder would otherwise be entitled to purchase upon such exercise, the Company shall, at its election, either pay a cash adjustment in
respect of such final fraction in an amount equal to such fraction multiplied by the Exercise Price or round up to the next whole share.


 


iv. Charges,
Taxes and Expenses. Issuance of Warrant Shares shall be made without charge to the Holder for any issue or transfer tax or other incidental
expense in respect of the issuance of such Warrant Shares, all of which taxes and expenses shall be paid by the Company, and such Warrant
Shares shall be issued in the name of the Holder or in such name or names as may be directed by the Holder; provided, however,
that, in the event that Warrant Shares are to be issued in a name other than the name of the Holder, this Warrant when surrendered for
exercise shall be accompanied by the Assignment Form attached hereto duly executed by the Holder and the Company may require, as a condition
thereto, the payment of a sum sufficient to reimburse it for any transfer tax incidental thereto. The Company shall pay all Transfer Agent
fees required for same-day processing of any Notice of Exercise and all fees to the Depository Trust Company (or another established clearing
corporation performing similar functions) required for same-day electronic delivery of the Warrant Shares.

v. Closing
of Books. The Company will not close its stockholder books or records in any manner which prevents the timely exercise of this Warrant,
pursuant to the terms hereof.


 


e) Holder’s
Exercise Limitations The Company shall not effect any exercise of this Warrant, and a Holder shall not have the right to exercise
any portion of this Warrant, pursuant to Section 2 or otherwise, to the extent that after giving effect to such issuance after exercise
as set forth on the applicable Notice of Exercise, the Holder (together with the Holder’s Affiliates, and any other Persons acting
as a group together with the Holder or any of the Holder’s Affiliates (such Persons, “Attribution Parties”)),
would beneficially own in excess of the Beneficial Ownership Limitation (as defined below). 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, nonexercised portion of this Warrant
beneficially owned by the Holder or any of its Affiliates or Attribution Parties and (ii) exercise or conversion of the unexercised or
nonconverted portion of any other securities of the Company (including, without limitation, any other Common Stock equivalents) subject
to a limitation on conversion or exercise analogous to the limitation contained herein beneficially owned by the Holder or any of its
Affiliates or Attribution Parties. Except as set forth in the preceding sentence, for purposes of this Section 2(e), beneficial ownership
shall be calculated in accordance with Section 13(d) of the Exchange Act and the rules and regulations promulgated thereunder, it being
acknowledged by the Holder that the Company is not representing to the Holder that such calculation is in compliance with Section 13(d)
of the Exchange Act and the Holder is solely responsible for any schedules required to be filed in accordance therewith. To the extent
that the limitation contained in this Section 2(e) 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’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’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. 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. 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 “Beneficial Ownership Limitation” shall
be 4.99% 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 limitations contained in this paragraph shall apply to a successor holder of this Warrant.

Section 3. Certain Adjustments.


 


a) Stock
Dividends and Splits. If the Company, at any time while this Warrant is outstanding: (i) pays a stock dividend or otherwise makes
a distribution or distributions on shares of its Common Stock or any other equity or equity equivalent securities payable in shares of
Common Stock (which, for avoidance of doubt, shall not include any shares of Common Stock issued by the Company upon exercise of this
Warrant), (ii) subdivides outstanding shares of Common Stock into a larger number of shares, (iii) combines (including by way of reverse
stock split) outstanding shares of Common Stock into a smaller number of shares, or (iv) issues by reclassification of shares of the Common
Stock any shares of capital stock of the Company, then in each case the Exercise Price shall be multiplied by a fraction of which the
numerator shall be the number of shares of Common Stock (excluding treasury shares, if any) outstanding immediately before such event
and of which the denominator shall be the number of shares of Common Stock outstanding immediately after such event, and the number of
shares issuable upon exercise of this Warrant shall be proportionately adjusted such that the aggregate Exercise Price of this Warrant
shall remain unchanged. Any adjustment made pursuant to this Section 3(a) shall become effective immediately after the record date for
the determination of stockholders entitled to receive such dividend or distribution and shall become effective immediately after the effective
date in the case of a subdivision, combination or re-classification.


 


b) Calculations.
All calculations under this Section 3 shall be made to the nearest cent or the nearest 1/100th of a share, as the case may be. For purposes
of this Section 3, the number of shares of Common Stock deemed to be issued and outstanding as of a given date shall be the sum of the
number of shares of Common Stock (excluding treasury shares, if any) issued and outstanding.


 


c) Notice
to Holder.


 


i. Adjustment
to Exercise Price. Whenever the Exercise Price is adjusted pursuant to any provision of this Section 3, the Company shall promptly
deliver to the Holder by facsimile or email a notice setting forth the Exercise Price after such adjustment and any resulting adjustment
to the number of Warrant Shares and setting forth a brief statement of the facts requiring such adjustment.

ii. Notice to Allow Exercise by Holder. If (A) the Company
shall declare a dividend (or any other distribution in whatever form) on the Common Stock, (B) the Company shall declare a special
nonrecurring cash dividend on or a redemption of the Common Stock, (C) the Company shall authorize the granting to all holders of
the Common Stock rights or warrants to subscribe for or purchase any shares of capital stock of any class or of any rights, (D) the
approval of any stockholders of the Company shall be required in connection with any reclassification of the Common Stock, any
consolidation or merger to which the Company (and all of its Subsidiaries, taken as a whole) is a party, any sale or transfer of all
or substantially all of the assets of the Company, or any compulsory share exchange whereby the Common Stock is converted into other
securities, cash or property, or (E) the Company shall authorize the voluntary or involuntary dissolution, liquidation or winding up
of the affairs of the Company, then, in each case, the Company shall cause to be delivered by facsimile or email to the Holder at
its last facsimile number or email address as it shall appear upon the Warrant Register of the Company, at least 20 calendar days
prior to the applicable record or effective date hereinafter specified, a notice stating (x) the date on which a record is to be
taken for the purpose of such dividend, distribution, redemption, rights or warrants, or if a record is not to be taken, the date as
of which the holders of the Common Stock of record to be entitled to such dividend, distributions, redemption, rights or warrants
are to be determined or (y) the date on which such reclassification, consolidation, merger, sale, transfer or share exchange is
expected to become effective or close, and the date as of which it is expected that holders of the Common Stock of record shall be
entitled to exchange their shares of the Common Stock for securities, cash or other property deliverable upon such reclassification,
consolidation, merger, sale, transfer or share exchange; provided that the failure to deliver such notice or any defect therein or
in the delivery thereof shall not affect the validity of the corporate action required to be specified in such notice. To the extent
that any notice provided in this Warrant constitutes, or contains, material, non-public information regarding the Company or any of
the Subsidiaries, the Company shall simultaneously file such notice with the Securities and Exchange Commission pursuant to a
Current Report on Form 8-K (to the extent the Company is a reporting company at the time of such event). The Holder shall remain
entitled to exercise this Warrant during the period commencing on the date of such notice to the effective date of the event
triggering such notice except as may otherwise be expressly set forth herein.

d) Voluntary Adjustment By Company. Subject to the rules
and regulations of the Trading Market, the Company may at any time during the term of this Warrant, subject to the prior written
consent of the Holder, and the terms of the Subscription Agreement, reduce the then current Exercise Price to any amount and for any
period of time deemed appropriate by the board of directors of the Company.


 


 Section 4. Transfer of Warrant.


 


a) Transferability.
Subject to compliance with any applicable securities laws and the conditions set forth in Section 4(d) hereof and to the provisions of
Section 4.1 of the Subscription Agreement, this Warrant and all rights hereunder (including, without limitation, any registration rights)
are transferable, in whole or in part, upon surrender of this Warrant at the principal office of the Company or its designated agent,
together with a written assignment of this Warrant substantially in the form attached hereto duly executed by the Holder or its agent
or attorney and funds sufficient to pay any transfer taxes payable upon the making of such transfer. Upon such surrender and, if required,
such payment, the Company shall execute and deliver a new Warrant or Warrants in the name of the assignee or assignees, as applicable,
and in the denomination or denominations specified in such instrument of assignment, and shall issue to the assignor a new Warrant evidencing
the portion of this Warrant not so assigned, and this Warrant shall promptly be cancelled. Upon partial transfer, the Company shall promptly
issue one or more Warrants representing the number of Shares purchasable thereunder to the assignee or assignees and the original holder,
if applicable. The Warrant, if properly assigned in accordance herewith, may be exercised by a new holder for the purchase of Warrant
Shares without having a new Warrant issued.


 


b) New
Warrants. This Warrant may be divided or combined with other Warrants upon presentation hereof at the aforesaid office of the Company,
together with a written notice specifying the names and denominations in which new Warrants are to be issued, signed by the Holder or
its agent or attorney. Subject to compliance with Section 4(a), as to any transfer which may be involved in such division or combination,
the Company shall execute and deliver a new Warrant or Warrants in exchange for the Warrant or Warrants to be divided or combined in accordance
with such notice. All Warrants issued on transfers or exchanges shall be dated the Initial Exercise Date and shall be identical with this
Warrant except as to the number of Warrant Shares issuable pursuant thereto.


 


c) Warrant
Register. The Company shall register this Warrant, upon records to be maintained by the Company for that purpose (the “Warrant
Register”), in the name of the record Holder hereof from time to time. The Company may deem and treat the registered Holder
of this Warrant as the absolute owner hereof for the purpose of any exercise hereof or any distribution to the Holder, and for all other
purposes, absent actual notice to the contrary.


 


d) Transfer
Restrictions. If, at the time of the surrender of this Warrant in connection with any transfer of this Warrant, the transfer of this
Warrant shall not be either (i) registered pursuant to an effective registration statement under the Securities Act and under applicable state securities or blue sky laws or (ii) eligible
for resale without volume or manner-of-sale restrictions or current public information requirements pursuant to Rule 144, the Company
may require, as a condition of allowing such transfer, that the Holder or transferee of this Warrant, as the case may be, comply with,
and make the same representations as, the Purchasers in the Subscription Agreement, including, but not limited to Section 2 of the Subscription
Agreement.

e) Representation
by the Holder. The Holder, by the acceptance hereof, represents and warrants that it is acquiring this Warrant and, upon any exercise
hereof, will acquire the Warrant Shares issuable upon such exercise, for its own account and not with a view to or for distributing or
reselling such Warrant Shares or any part thereof in violation of the Securities Act or any applicable state securities law, except pursuant
to sales registered or exempted under the Securities Act.


 


Section 5. Miscellaneous.


 


a) No
Rights as Stockholder Until Exercise; No Settlement in Cash. This Warrant does not entitle the Holder to any voting rights, dividends
or other rights as a stockholder of the Company prior to the exercise hereof as set forth in Section 2(d)(i), except as expressly set
forth in Section 3. Without limiting any rights of a Holder to receive Warrant Shares on a “cashless exercise” pursuant to
Section 2(c) herein, in no event shall the Company be required to net cash settle an exercise of this Warrant.


 


b) Loss,
Theft, Destruction or Mutilation of Warrant. The Company covenants that upon receipt by the Company of evidence reasonably satisfactory
to it of the loss, theft, destruction or mutilation of this Warrant or any stock certificate relating to the Warrant Shares, and in case
of loss, theft or destruction, of indemnity or security reasonably satisfactory to it (which, in the case of the Warrant, shall not include
the posting of any bond), and upon surrender and cancellation of such Warrant or stock certificate, if mutilated, the Company will make
and deliver a new Warrant or stock certificate of like tenor and dated as of such cancellation, in lieu of such Warrant or stock certificate.


 


c) Saturdays,
Sundays, Holidays, etc. If the last or appointed day for the taking of any action or the expiration of any right required or granted
herein shall not be a Business Day, then such action may be taken or such right may be exercised on the next succeeding Business Day.


 


d) Authorized
Shares.


 


The Company covenants that, during the period the
Warrant is outstanding, it will reserve from its authorized and unissued Common Stock a sufficient number of shares to provide for the
issuance of the Warrant Shares upon the exercise of any purchase rights under this Warrant. The Company further covenants that its issuance
of this Warrant shall constitute full authority to its officers who are charged with the duty of issuing the necessary Warrant Shares
upon the exercise of the purchase rights under this Warrant. The Company will take all such reasonable action as may be necessary to assure that
such Warrant Shares may be issued as provided herein without violation of any applicable law or regulation, or of any requirements of
the Trading Market upon which the Common Stock may be listed. The Company covenants that all Warrant Shares which may be issued upon the
exercise of the purchase rights represented by this Warrant will, upon exercise of the purchase rights represented by this Warrant and
payment for such Warrant Shares in accordance herewith, be duly authorized, validly issued, fully paid and nonassessable and free from
all taxes, liens and charges created by the Company in respect of the issue thereof (other than taxes in respect of any transfer occurring
contemporaneously with such issue).


 


Warrant #


 




    10


     


    

 


Except and to the extent as waived or consented
to by the Holder, the Company shall not by any action, including, without limitation, amending its articles of incorporation or through
any reorganization, transfer of assets, consolidation, merger, dissolution, issue or sale of securities or any other voluntary action,
avoid or seek to avoid the observance or performance of any of the terms of this Warrant, but will at all times in good faith assist in
the carrying out of all such terms and in the taking of all such actions as may be necessary or appropriate to protect the rights of Holder
as set forth in this Warrant against impairment. Without limiting the generality of the foregoing, the Company will (i) not increase the
par value of any Warrant Shares above the amount payable therefor upon such exercise immediately prior to such increase in par value,
(ii) take all such action as may be necessary or appropriate in order that the Company may validly and legally issue fully paid and nonassessable
Warrant Shares upon the exercise of this Warrant and (iii) use commercially reasonable efforts to obtain all such authorizations, exemptions
or consents from any public regulatory body having jurisdiction thereof, as may be, necessary to enable the Company to perform its obligations
under this Warrant.


 


Before taking any action which would result in
an adjustment in the number of Warrant Shares for which this Warrant is exercisable or in the Exercise Price, the Company shall obtain
all such authorizations or exemptions thereof, or consents thereto, as may be necessary from any public regulatory body or bodies having
jurisdiction thereof.


 


e) Jurisdiction.
All questions concerning the construction, validity, enforcement and interpretation of this Warrant shall be determined in accordance
with the provisions of the Subscription Agreement.


 


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


 


g) Nonwaiver
and Expenses. No course of dealing or any delay or failure to exercise any right hereunder on the part of Holder shall operate as
a waiver of such right or otherwise prejudice the Holder’s rights, powers or remedies. Without limiting any other provision of this Warrant or the Subscription Agreement, if the Company
willfully and knowingly fails to comply with any provision of this Warrant, which results in any material damages to the Holder, the Company
shall pay to the Holder such amounts as shall be sufficient to cover any costs and expenses including, but not limited to, reasonable
attorneys’ fees, including those of appellate proceedings, incurred by the Holder in collecting any amounts due pursuant hereto
or in otherwise enforcing any of its rights, powers or remedies hereunder.

h) Notices.
Any notice, request or other document required or permitted to be given or delivered to the Holder by the Company shall be delivered in
accordance with the notice provisions of the Subscription Agreement.


 


i) Limitation
of Liability. No provision hereof, in the absence of any affirmative action by the Holder to exercise this Warrant to purchase Warrant
Shares, and no enumeration herein of the rights or privileges of the Holder, shall give rise to any liability of the Holder for the purchase
price of any Common Stock or as a stockholder of the Company, whether such liability is asserted by the Company or by creditors of the
Company.


 


j) Successors
and Assigns. Subject to applicable securities laws, this Warrant and the rights and obligations evidenced hereby shall inure to the
benefit of and be binding upon the successors and permitted assigns of the Company and the successors and permitted assigns of Holder.
The provisions of this Warrant are intended to be for the benefit of any Holder from time to time of this Warrant and shall be enforceable
by the Holder or holder of Warrant Shares.


 


k) Amendment.
This Warrant may not be modified or amended or the provisions hereof waived without the written consent of the Company and the Holder
of this Warrant.


 


l) Severability.
Wherever possible, each provision of this Warrant shall be interpreted in such manner as to be effective and valid under applicable law,
but if any provision of this 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 provisions or the remaining provisions of this Warrant.


 


m) Headings.
The headings used in this Warrant are for the convenience of reference only and shall not, for any purpose, be deemed a part of this Warrant.

EXHIBIT F


 


Disbursement Agreement


 


DISBURSEMENT AGREEMENT


 


This Escrow Agreement (“Agreement”)
is entered into among EPIEN Medical, Inc., a Minnesota corporation (“Company”), and the purchaser (“Purchaser”)
listed on Schedule A to the Subscription Agreement between the Company and Purchaser (“Subscription”), in which
this Agreement is attached as Exhibit E thereto and deemed merged and integrated into the Agreement, and (name). All capitalized
terms herein are defined in the Subscription unless otherwise noted. Company and Purchaser are collectively referred to herein as the
“Disbursing Parties.”


 


WHEREAS, in addition to the Subscription,
Disbursing Parties are parties to the following related agreements: (a) Secured Convertible Promissory Note, (b) Security Agreement, and
(c) Common Stock Purchase Warrant (collectively, along with the Subscription, “Investment Documents”).


 


WHEREAS, pursuant to the Subscription, the
Consideration is to be deposited with the (name) in its attorney-client trust account (“Disbursing Account”)
for disbursement pursuant to the terms therein, and the parties agree that such funds may be commingled by the (name) in the Disbursing
Account with other escrowed funds on deposit with the (name).


 


WHEREAS, by executing the Subscription,
Purchaser agrees to be bound by the terms and conditions of this Agreement.


 


WHEREAS, in order to establish the Disbursing
Account and to effectuate certain provisions of the Subscription, the parties hereto have entered into this Agreement.


 


NOW THEREFORE, for good and valuable consideration,
the receipt and sufficiency of which are hereby acknowledged, the parties hereto, for themselves, their successors and assigns, hereby
agree as follows:


 


1. Appointment of (name).
Disbursing Parties hereby appoint (name) to serve hereunder. (name) hereby accepts such appointment and agrees to hold
and distribute the Consideration on the Closing Date pursuant to and in accordance with the Subscription, and more specifically
Section 1.7 thereto, and this Agreement. Disbursing Parties agree that the (name) shall not accept for deposit or retain any
Investment Documents, unless otherwise agreed to by the parties in a writing supplementing the terms of this Agreement. The Company
shall provide written notice to the (name) and Purchaser directing (name) to release the Consideration as provided for
in Section 1.7 of the Agreement or to return the Consideration to Purchaser (“Release Notice”). The (name) shall
release the Consideration in the manner set forth in the Release Notice within twenty-four (24) hours of receipt of the Release
Notice. The failure of Purchaser to object to the Release Notice shall constitute Purchaser’s acceptance of the release of the
Consideration, and shall constitute a release of the (name) by the Disbursing Parties of any and all claims or actions
against the (name). Notwithstanding anything to the contrary herein, the parties agree the (name) shall retain sole
discretion in determining whether a dispute arises between the Company and Purchaser related to the Consideration in the Disbursing
Account, and the parties agree that the (name) may exercise its sole discretion in determining whether such a dispute
warrants interpleading such funds with a court of competent jurisdiction (“Interpleader”). Upon
instituting an Interpleader action and depositing the disputed funds with the court in such action, the (name) shall be fully
relieved from any and all liability or obligation with respect to such interpleaded documents or funds.


 




    1


     


    

  


2. (name)
Expenses. The Company agrees to pay (a) (amount) to (name) for establishing the Trust Account and for
preparation of this Agreement, and (b) (amount) for each distribution of Consideration out of the Trust Account. In the event of
Interpleader, the Disbursing Parties shall split equally the payment for those costs and fees, including but not limited to reasonable
attorneys fees, incurred by the (name) in the Interpleader.


 


3. Reliance
by the (name). The (name) shall not be responsible for the authenticity of any documents or signatures and may rely
exclusively on and shall be protected when acting on any notice, affidavit, request, consent, instruction, check, or other document that
it believes in good faith to be genuine, signed or presented by the proper person, duly authorized, or properly made. The (name) shall
have no responsibility except the performance of its duties as stated herein, and no additional duties shall be inferred or implied under
this Agreement.


 


4. Nature
of (name) Obligations. The (name) shall have no duties or responsibilities other than those expressly
set forth herein. The (name) shall have no duty to enforce any obligation of any person to make any payment or delivery, or to
direct or cause any payment or delivery to be made, or to enforce any obligation of any person to perform any other act. The (name)
shall be under no liability to the Disbursing Parties or anyone else, by reason of any failure, on the part of any Party or any maker,
guarantor, endorser or other signatory of a document or any other person, to perform such person’s obligations under any such document.
Except for amendments to this Agreement, and except for written instructions given to the (name) by the Disbursing Parties relating
to the Subscription Documents, the (name) shall not be obligated to recognize any agreement between or among any of the Disbursing
Parties, notwithstanding that references hereto may be made herein and whether or not it has knowledge thereof.


 


The (name) shall not be liable to the Disbursing
Parties or to anyone else for any action taken or omitted by it, or any action suffered by it to be taken or omitted, in good faith and
acting upon any order, notice, demand, certificate, opinion or advice of counsel (including counsel chosen by the (name)), statement,
instrument, report, or other paper or document (not only as to its due execution and the validity and effectiveness of its provisions,
but also as to the truth and acceptability of any information therein contained), which a reasonable person would believe to be genuine
and to be signed or presented by the proper person or persons. The (name) shall not be bound by any of the terms thereof, unless
evidenced by written notice delivered to the (name) signed by the proper party or parties and, if the duties or rights of the (name)
are affected, unless it shall give its prior written consent thereto.


 


The (name) shall not be responsible for
the sufficiency or accuracy of the form, or of the execution, validity, value or genuineness of, any document or property received, held
or delivered to it hereunder, or of any signature or endorsement thereon, or for any lack of endorsement thereon, or for any description
therein, unless the (name) had reason to know of the deficiency of any such form, document, or property; nor shall the (name)
be responsible or liable to the Disbursing Parties, or to anyone else in any respect on account of the identity, authority or rights,
of the person executing or delivering or purporting to execute or deliver any document
or property or this Agreement, unless the (name) had reason to know of the lack of authority or rights of the person executing
or purporting to execute or deliver the document or property. The (name) shall have no responsibility with respect to the use or
application of the Investments pursuant to the provisions hereof.


 




    2


     


    




 





The (name) shall have the right to assume,
based on reasonable inference, in the absence of written notice to the contrary from the proper person or persons, that a fact or an event,
by reason of which an action would or might be taken by the (name), does not exist or has not occurred, without incurring liability
to the Disbursing Parties, or to anyone else for any action taken or omitted to be taken or omitted, in good faith and in the exercise
of reasonable judgment.


 


To the extent that the (name) becomes liable
for the payment of taxes, including withholding taxes, in respect of income derived from the deposit of the Investments, or any payment
made hereunder, the (name) may pay such taxes; and the (name) may withhold from any payment of the Investments such amount
as the (name) estimates to be sufficient to provide for the payment of such taxes not yet paid, and may use the sum withheld for
that purpose. The (name) shall be indemnified and held harmless against any liability for taxes and for any penalties in respect
of taxes.


 


The (name) will be indemnified and held
harmless by the Disbursing Parties from and against all expenses, including all counsel fees and disbursements, or loss suffered by the
(name) in connection with any action, suit or proceedings involving any claim, or in connection with any claim or demand, which
in any way, directly or indirectly, arises out of or relates to this Agreement, the services of the (name) hereunder, except for
claims relating to negligence or intentional wrongdoing by (name) or breach of this Agreement by the (name), or the monies
or other property held by it hereunder.


 


5. Miscellaneous.
The Disbursing Parties consent to the This Agreement and the rights and obligations hereunder of the (name) may only be assigned
by the (name) upon receiving informed written consent of the Disbursing Parties. This Agreement shall be binding upon and inure
to the benefit of each party’s respective successors, heirs and permitted assigns. No other person shall acquire or have any rights
under or by virtue of this Agreement. This Agreement may not be changed orally or modified, amended or supplemented without an express
written agreement executed by the (name) and the Disbursing Parties. This Agreement is intended to be for the sole benefit of the
parties hereto and their respective successors, heirs and permitted assigns, and none of the provisions of this Agreement are intended
to be, nor shall they be construed to be, for the benefit of any third person. This Agreement shall be governed by, and construed in accordance
with, the internal laws of the State of Michigan. The representations and warranties contained in this Agreement shall survive the execution
and delivery hereof and any investigations made by any Party. The headings in this Agreement are for purposes of reference only and shall
not limit or otherwise affect any of the terms thereof.


 


6. Counterpart;
Electronic and Facsimile Signatures. This Agreement may be executed in counterpart with electronic and facsimile signatures constituting
originals.


 


7. Termination. This Escrow Agreement
will terminate upon the final distribution of all of the Consideration.
