Exhibit 4.4


 


Warrant
Agent Agreement


 


This WARRANT AGENT AGREEMENT
(this “Warrant Agreement”) dated as of [●], 2022 (the “Issuance Date”) is between EPIEN Medical,
Inc., a Nevada corporation (the “Company”), and VStock Transfer, LLC, a New York Limited Liability Company (the “Warrant
Agent”).


 


WHEREAS, pursuant to the terms
of that certain Underwriting Agreement (“Underwriting Agreement”), dated [●], 2022, by and among the Company
and EF Hutton, division of Benchmark Investments, LLC, as the underwriter set forth therein (the “Underwriter”), the
Company is engaged in a public offering of up to [●] units (each, a “Closing Unit”), with each Closing Unit consisting
of (1) one share of common stock, $.0001 par value, (the “Common Shares”) of the Company, and one (1) warrant to purchase
one Common Share at an exercise price of $[●] (representing 100% of the per share price of the Closing Share (the “Warrants”)).


 


WHEREAS, the Company has filed
with the Securities and Exchange Commission (the “Commission”) a Registration Statement on Form S-1(File No. 333-[●])
(as the same may be amended from time to time, the “Registration Statement”), for the registration under the Securities
Act of 1933, as amended (the “Securities Act”), of the Closing Units, Common Shares, Warrants, and shares underlying
Warrants, and such Registration Statement was declared effective on [●], 2022; and


 


WHEREAS, the Company desires
the Warrant Agent to act on behalf of the Company, and the Warrant Agent is willing to so act, in accordance with the terms set forth
in this Warrant Agreement in connection with the issuance, registration, transfer, exchange and exercise of the Warrants;


 


WHEREAS, the Company desires
to provide for the provisions of the Warrants, the terms upon which they shall be issued and exercised, and the respective rights, limitation
of rights, and immunities of the Company, the Warrant Agent, and the holders of the Warrants; and


 


WHEREAS, all acts and things
have been done and performed which are necessary to make the Warrants the valid, binding and legal obligations of the Company, and to
authorize the execution and delivery of this Warrant Agreement.


 


NOW, THEREFORE, in consideration
of the mutual agreements herein contained, the parties hereto agree as follows:


 


1. Appointment of Warrant Agent. The
Company hereby appoints the Warrant Agent to act as agent for the Company with respect to the Warrants, and the Warrant Agent hereby accepts
such appointment and agrees to perform the same in accordance with the express terms and conditions set forth in this Warrant Agreement
(and no implied terms or conditions).


 


2. Warrants.


 


2.1. Form of Warrants.
The Warrants shall be registered securities and shall be evidenced by a global warrant (“Global Warrant”) in the form
of Exhibit A to this Warrant Agreement, which shall be deposited on behalf of the Company with a custodian for The Depository
Trust Company (“DTC”) and registered in the name of Cede & Co., a nominee of DTC. The terms of the Global Warrant
are incorporated herein by reference. If DTC subsequently ceases to make its book-entry settlement system available for the Warrants,
the Company may instruct the Warrant Agent regarding making other arrangements for book-entry settlement. In the event that the Warrants
are not eligible for, or it is no longer necessary to have the Warrants available in, book-entry form, the Company may instruct the Warrant
Agent to provide written instructions to DTC to deliver to the Warrant Agent for cancellation the Global Warrant, and the Company shall
instruct the Warrant Agent to deliver to DTC separate certificates evidencing Warrants (“Definitive Certificates” and,
together with the Global Warrant, “Warrant Certificates”) registered as requested through the DTC system.


  









     


     


    

 


2.2. Issuance and
Registration of Warrants.


 


2.2.1. Warrant Register.
The Warrant Agent shall maintain books (“Warrant Register”) for the registration of original issuance and the registration
of transfer of the Warrants.


 


2.2.2. Issuance of Warrants.
Upon the initial issuance of the Warrants, the Warrant Agent shall issue the Global Warrant and deliver the Warrants in the DTC book-entry
settlement system in accordance with written instructions delivered to the Warrant Agent by the Company. Ownership of security entitlements
in the Warrants shall be shown on, and the transfer of such ownership shall be effected through, records maintained (i) by DTC and (ii)
by institutions that have accounts with DTC (each, a “Participant”).


 


2.2.3. Beneficial Owner;
Holder. Prior to due presentment for registration of transfer of any Warrant, the Company and the Warrant Agent may deem and treat
the person in whose name that Warrant shall be registered on the Warrant Register (the “Holder”) as the absolute owner
of such Warrant for purposes of any exercise thereof, and for all other purposes, and neither the Company nor the Warrant Agent shall
be affected by any notice to the contrary. Notwithstanding the foregoing, nothing herein shall prevent the Company, the Warrant Agent
or any agent of the Company or the Warrant Agent from giving effect to any written certification, proxy or other authorization furnished
by DTC governing the exercise of the rights of a holder of a beneficial interest in any Warrant. The rights of beneficial owners in a
Warrant evidenced by the Global Warrant shall be exercised by the Holder or a Participant through the DTC system, except to the extent
set forth herein or in the Global Warrant.


 


2.2.4. Delivery of Warrant
Certificate. A Holder has the right to elect at any time or from time to time a Warrant Exchange (as defined below) pursuant to a
Warrant Certificate Request Notice (as defined below). Upon written notice by a Holder to the Warrant Agent for the exchange of some or
all of such Holder’s Warrants for a Warrant Certificate evidencing the same number of Warrants, which request shall be in the form
attached hereto as Exhibit B (a “Warrant Certificate Request Notice” and the date of delivery of such
Warrant Certificate Request Notice by the Holder, the “Warrant Certificate Request Notice Date” and the deemed surrender
upon delivery by the Holder of a number of Global Warrants for the same number of Warrants evidenced by a Warrant Certificate, a “Warrant
Exchange”), the Warrant Agent shall promptly effect the Warrant Exchange and shall promptly issue and deliver to the Holder
a Warrant Certificate for such number of Warrants in the name set forth in the Warrant Certificate Request Notice. Such Warrant Certificate
shall be dated the date of issuance of the Warrant Certificate, shall include the initial exercise date of the Warrants, shall be executed
by an authorized signatory of the Company and shall be reasonably acceptable in all respects to such Holder. In connection with a Warrant
Exchange, the Company agrees to deliver, or to direct the Warrant Agent to deliver, the Warrant Certificate to the Holder within three
(3) business days of the Warrant Certificate Request Notice pursuant to the delivery instructions in the Warrant Certificate Request Notice
(“Warrant Certificate Delivery Date”). If the Company fails for any reason to deliver to the Holder the Warrant Certificate
subject to the Warrant Certificate Request Notice by the Warrant Certificate Delivery Date, the Company shall pay to the Holder, in cash,
as liquidated damages and not as a penalty, for each $1,000 of Common Shares issuable upon exercise of the Warrants (the “Warrant
Shares”) evidenced by such Warrant Certificate (based on the VWAP (as defined in the Warrants) of the Common Shares on the Warrant
Certificate Request Notice Date), $10 per business day for each business day after such Warrant Certificate Delivery Date until such Warrant
Certificate is delivered or, prior to delivery of such Warrant Certificate, the Holder rescinds such Warrant Exchange. The Company covenants
and agrees that, upon the date of delivery of the Warrant Certificate Request Notice, the Holder shall be deemed to be the holder of the
Warrant Certificate and, notwithstanding anything to the contrary set forth herein, the Warrant Certificate shall be deemed for all purposes
to contain all of the terms and conditions of the Warrants evidenced by such Warrant Certificate and the terms of this Agreement.


 


2.2.5. Execution.
The Warrant Certificates shall be executed on behalf of the Company by any authorized officer of the Company (an “Authorized
Officer”), which need not be the same authorized signatory for all of the Warrant Certificates, either manually or by facsimile
signature. The Warrant Certificates shall be countersigned by an authorized signatory of the Warrant Agent, which need not be the same
signatory for all of the Warrant Certificates, either manually or by facsimile signature, and no Warrant Certificate shall be valid for
any purpose unless so countersigned. In case any Authorized Officer of the Company that signed any of the Warrant Certificates ceases
to be an Authorized Officer of the Company before countersignature by the Warrant Agent and issuance and delivery by the Company, such
Warrant Certificates, nevertheless, may be countersigned by the Warrant Agent, issued and delivered with the same force and effect as
though the person who signed such Warrant Certificates had not ceased to be such officer of the Company; and any Warrant Certificate may
be signed on behalf of the Company by any person who, at the actual date of the execution of such Warrant Certificate, shall be an Authorized
Officer of the Company authorized to sign such Warrant Certificate, although at the date of the execution of this Warrant Agreement any
such person was not such an Authorized Officer.

2.2.6. Registration
of Transfer. At any time at or prior to the Termination date (as defined in the form of Warrant (Exhibit A)), a transfer of any Warrants
may be registered and any Warrant Certificate or Warrant Certificates may be split up, combined or exchanged for another Warrant Certificate
or Warrant Certificates evidencing the same number of Warrants as the Warrant Certificate or Warrant Certificates surrendered. Any Holder
desiring to register the transfer of Warrants or to split up, combine or exchange any Warrant Certificate shall make such request in writing
delivered to the Warrant Agent, and shall surrender to the Warrant Agent the Warrant Certificate or Warrant Certificates evidencing the
Warrants the transfer of which is to be registered or that is or are to be split up, combined or exchanged and, in the case of registration
of transfer, shall provide a signature guarantee. Thereupon, the Warrant Agent shall countersign and deliver to the person entitled thereto
a Warrant Certificate or Warrant Certificates, as the case may be, as so requested. The Company and the Warrant Agent may require payment,
by the Holder requesting a registration of transfer of Warrants or a split-up, combination or exchange of a Warrant Certificate (but,
for purposes of clarity, not upon the exercise of the Warrants and issuance of Warrant Shares to the Holder), of a sum sufficient to cover
any tax or governmental charge that may be imposed in connection with such registration of transfer, split-up, combination or exchange,
together with reimbursement to the Company and the Warrant Agent of all reasonable expenses incidental thereto.


 


2.2.7. Loss, Theft and
Mutilation of Warrant Certificates. Upon receipt by the Company and the Warrant Agent of evidence reasonably satisfactory to them
of the loss, theft, destruction or mutilation of a Warrant Certificate, and, in case of loss, theft or destruction, of indemnity or security
in customary form and amount, and reimbursement to the Company and the Warrant Agent of all reasonable expenses incidental thereto, and
upon surrender to the Warrant Agent and cancellation of the Warrant Certificate if mutilated, the Warrant Agent shall, on behalf of the
Company, countersign and deliver a new Warrant Certificate of like tenor to the Holder in lieu of the Warrant Certificate so lost, stolen,
destroyed or mutilated. The Warrant Agent may charge the Holder an administrative fee for processing the replacement of lost Warrant Certificates.
The Warrant Agent may receive compensation from the surety companies or surety agents for administrative services provided to them.


 


2.2.8. Proxies.
The Holder of a Warrant may grant proxies or otherwise authorize any person, including the Participants and beneficial holders that may
own interests through the Participants, to take any action that a Holder is entitled to take under this Agreement or the Warrants; provided, however,
that at all times that Warrants are evidenced by a Global Warrant, exercise of those Warrants shall be effected on their behalf by Participants
through DTC in accordance the procedures administered by DTC.


 


3. Terms and Exercise of Warrants.


 


3.1. Exercise Price.
Each Warrant shall entitle the Holder, subject to the provisions of the applicable Warrant Certificate and of this Warrant Agreement,
to purchase from the Company the number of Common Shares stated therein, at the price of $[●] per whole share, subject to the subsequent
adjustments provided in the Global Warrant. The term “Exercise Price” as used in this Warrant Agreement refers to the
price per share at which the Common Shares may be purchased at the time a Warrant is exercised.


 


3.2. Duration of Warrants.
A Warrant may be exercised only during the period (“Exercise Period”) commencing on the date of issuance and ending
on the Termination Date. For purposes of this Warrant Agreement, the “Termination Date” shall have the
meaning set forth in the Global Warrant (Exhibit A). Each Warrant not exercised on or before the Termination Date shall become void, and
all rights thereunder and all rights in respect thereof under this Agreement shall cease at the close of business on the Termination Date.


  






    3


     


    

 


3.3. Exercise of Warrants.


 


3.3.1. Exercise.
Subject to the provisions of the Global Warrant, a Holder (or a Participant or a designee of a Participant acting on behalf of a Holder)
may exercise Warrants by (i) (A) in the case of a holder registered with the Warrant Agent, delivering to the Warrant Agent a notice of
exercise of the Warrants to be exercised in the form attached to the Global Warrant or (B) in the case of a DTC settlement, via an electronic
warrant exercise through the DTC system (each, an “Election to Purchase”), in each case not later than 5:00 P.M., Eastern
Standard Time, on any business day during the Exercise Period, and (ii) within one (1) Trading Day of the Date of Exercise, delivering
Warrants to be exercised by (A) surrender of the Warrant Certificate evidencing the Warrants to the Warrant Agent at its office designated
for such purpose or (B) delivery of the Warrants to an account of the Warrant Agent at DTC designated for such purpose in writing by the
Warrant Agent to DTC from time to time. Partial exercises of a Warrant resulting in purchases of a portion of the total number of Warrant
Shares available thereunder 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. To initiate a partial-exercise, the Holder shall be required to physically
surrender a Warrant Certificate to the Warrant Agent, and remaining balance will be evidenced by a new Warrant Certificate. All other
requirements for the exercise of a Warrant shall be as set forth in the Warrant.


 


3.3.2. The Warrant Agent shall,
by 5:00 p.m., New York City time, on the Trading Day following the Exercise Date of any Warrant, advise the Company, the transfer agent
and registrar for the Company’s Common Shares, in respect of (i) the number of Warrant Shares indicated on the Notice of Exercise
as issuable upon such exercise with respect to such exercised Warrants, (ii) the instructions of the Holder or Participant, as the case
may be, provided to the Warrant Agent with respect to the delivery of the Warrant Shares and the number of Warrants that remain outstanding
after such exercise and (iii) such other information as the Company or such transfer agent and registrar shall reasonably request. The
Company shall issue the Warrant Shares in compliance with the terms of the Warrant.


 


3.3.3. Valid Issuance.
All Warrant Shares issued by the Company upon the proper exercise of a Warrant in conformity with this Warrant Agreement shall be validly
issued, fully paid and non-assessable.


 


3.3.4. No Fractional
Exercise. Notwithstanding any provision contained in this Warrant Agreement to the contrary, no fractional shares or scrip representing
fractional shares shall be issued upon the exercise of the 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.


 


3.3.5. No Transfer Taxes.
The Company shall not be required to pay any stamp or other tax or governmental charge required to be paid in connection with any transfer
involved in the issue of the Warrant Shares upon the exercise of Warrants; and in the event that any such transfer is involved, the Company
shall not be required to issue or deliver any Warrant Shares until such tax or other charge shall have been paid or it has been established
to the Company’s satisfaction that no such tax or other charge is due.


 


3.3.6. Date of Issuance.
The Company will treat an exercising Holder as a beneficial owner of the Warrant Shares as of the Exercise Date, and for purposes of Regulation
SHO, a holder whose interest in this Warrant is a beneficial interest in certificate(s) representing this Warrant held in book-entry form
through DTC shall be deemed to have exercised its interest in this Warrant upon instructing its broker that is a DTC participant to exercise
its interest in this Warrant, except that, if the Exercise Date is a date when the share transfer books of the Company are closed, such
person shall be deemed to have become the holder of such shares at the open of business on the next succeeding date on which the share
transfer books are open.


 


4. Adjustments. Upon every adjustment
of the Exercise Price or the number of Warrant Shares issuable upon exercise of a Warrant, the Company shall give written notice thereof
to the Warrant Agent, which notice shall state the Exercise Price resulting from such adjustment and the increase or decrease, if any,
in the number of Warrant Shares purchasable at such price upon the exercise of a Warrant, setting forth in reasonable detail the method
of calculation and the facts upon which such calculation is based. Upon the occurrence of any event specified in Section 3 of the Warrant,
then, in any such event, the Company shall give written notice to the Warrant Agent. Failure to give such notice, or any defect therein,
shall not affect the legality or validity of such event. The Warrant Agent shall be entitled to rely conclusively on, and shall be fully
protected in relying on, any certificate, notice or instructions provided by the Company with respect to any adjustment of the Exercise
Price or the number of shares issuable upon exercise of a Warrant, or any related matter, and the Warrant Agent shall not be liable for
any action taken, suffered or omitted to be taken by it in accordance with any such certificate, notice or instructions or pursuant to
this Warrant Agreement. The Warrant Agent shall not be deemed to have knowledge of any such adjustment unless and until it shall have
received written notice thereof from the Company.


 






    4


     


    

 


5. Restrictive Legends; Fractional Warrants.
In the event that a Warrant Certificate surrendered for transfer bears a restrictive legend, the Warrant Agent shall not register that
transfer until the Warrant Agent has received an opinion of counsel for the Company stating that such transfer may be made and indicating
whether the Warrants must also bear a restrictive legend upon that transfer. The Warrant Agent shall not be required to effect any registration
of transfer or exchange which will result in the transfer of or delivery of a Warrant Certificate for a fraction of a Warrant.


 


6. Other Provisions Relating to Rights
of Holders of Warrants.


 


6.1. No Rights as
Shareholder Except as otherwise specifically provided herein, a Holder, solely in its capacity as a holder of Warrants, shall not
be entitled to vote or receive dividends or be deemed the holder of share capital of the Company for any purpose, nor shall anything contained
in this Warrant Agreement be construed to confer upon a Holder, solely in its capacity as the registered holder of Warrants, any of the
rights of a shareholder the Company or any right to vote, give or withhold consent to any corporate action (whether any reorganization,
issue of Common Shares, reclassification of share capital, consolidation, merger, conveyance or otherwise), receive notice of meetings,
receive dividends or subscription rights or rights to participate in new issues of shares, or otherwise, prior to the issuance to the
Holder of the Warrant Shares which it is then entitled to receive upon the due exercise of Warrants.


 


6.2. Reservation of
Common Shares. The Company shall at all times reserve and keep available a number of its authorized but unissued Common Shares that
will be sufficient to permit the exercise in full of all outstanding Warrants issued pursuant to this Warrant Agreement.


 


7. Concerning the Warrant Agent and Other
Matters.


 


7.1. Any instructions given
to the Warrant Agent orally, as permitted by any provision of this Warrant Agreement, shall be confirmed in writing by the Company as
soon as practicable. The Warrant Agent shall not be liable or responsible and shall be fully authorized and protected for acting, or failing
to act, in accordance with any oral instructions which do not conform with the written confirmation received in accordance with this Section
7.1.


 


7.2. (a) Whether or not any

in connection with this Warrant Agreement, including, without limitation, the fees and expenses of the Warrant Agent’s counsel.

not reflect actual out-of-pocket costs, and may include handling charges to cover internal processing and use of the Warrant Agent’s
billing systems. (b) All amounts owed by the Company to the Warrant Agent under this Warrant Agreement are due within 30 days of the invoice

delinquent payments. (c) No provision of this Warrant Agreement shall require Warrant Agent to expend or risk its own funds or otherwise
incur any financial liability in the performance of any of its duties under this Warrant Agreement or in the exercise of its rights.


  


7.3. As agent for the Company
hereunder the Warrant Agent: (a) shall have no duties or obligations other than those specifically set forth herein or as may subsequently
be agreed to in writing by the Warrant Agent and the Company; (b) shall be regarded as making no representations and having no responsibilities
as to the validity, sufficiency, value, or genuineness of the Warrants or any Warrant Shares; (c) shall not be obligated to take any legal
action hereunder; if, however, the Warrant Agent determines to take any legal action hereunder, and where the taking of such action might,
in its judgment, subject or expose it to any expense or liability it shall not be required to act unless it has been furnished with an
indemnity reasonably satisfactory to it; (d) may rely on and shall be fully authorized and protected in acting or failing to act upon
any certificate, instrument, opinion, notice, letter, telegram, telex, facsimile transmission or other document or security delivered

or responsible for any recital or statement contained in the Registration Statement or any other documents relating thereto; (f) shall

any earlier date) unless prior to taking any such action, the Warrant Agent shall have received written instructions in response to such
application specifying the action to be taken or omitted; (h) may consult with counsel satisfactory to the Warrant Agent, including its
in-house counsel, and the advice of such counsel shall be full and complete authorization and protection in respect of any action taken,

7.4. (a) In the absence of gross negligence or
willful or illegal misconduct on its part, the Warrant Agent shall not be liable for any action taken, suffered, or omitted by it or for
any error of judgment made by it in the performance of its duties under this Warrant Agreement. Anything in this Warrant Agreement to
the contrary notwithstanding, in no event shall Warrant Agent be liable for special, indirect, incidental, consequential or punitive losses
or damages of any kind whatsoever (including but not limited to lost profits, liquidated damages or buy-in claims), even if the Warrant
Agent has been advised of the possibility of such losses or damages and regardless of the form of action. Any liability of the Warrant
Agent will be limited in the aggregate to the amount of fees paid by the Company hereunder. The Warrant Agent shall not be liable for
any failures, delays or losses, arising directly or indirectly out of conditions beyond its reasonable control including, but not limited
to, acts of government, exchange or market ruling, suspension of trading, work stoppages or labor disputes, fires, civil disobedience,
riots, rebellions, storms, electrical or mechanical failure, computer hardware or software failure, communications facilities failures
including telephone failure, war, terrorism, insurrection, earthquakes, floods, acts of God or similar occurrences. (b) In the event any
question or dispute arises with respect to the proper interpretation of the Warrants or the Warrant Agent’s duties under this Warrant
Agreement or the rights of the Company or of any Holder, the Warrant Agent shall not be required to act and shall not be held liable or
responsible for its refusal to act until the question or dispute has been judicially settled (and, if appropriate, it may file a suit
in interpleader or for a declaratory judgment for such purpose) by final judgment rendered by a court of competent jurisdiction, binding
on all persons interested in the matter which is no longer subject to review or appeal, or settled by a written document in form and substance
satisfactory to Warrant Agent and executed by the Company and each such Holder. In addition, the Warrant Agent may require for such purpose,
but shall not be obligated to require, the execution of such written settlement by all the Holders and all other persons that may have
an interest in the settlement.


 


7.5. The Company covenants
to indemnify the Warrant Agent and hold it harmless from and against any loss, liability, claim or expense (“Loss”)
arising out of or in connection with the Warrant Agent’s duties under this Warrant Agreement, including the costs and expenses of
defending itself against any Loss, unless such Loss shall have been determined by a court of competent jurisdiction to be a result of
the Warrant Agent’s gross negligence or willful misconduct.


  


7.6. Unless terminated earlier
by the parties hereto, this Agreement shall terminate 90 days after the earlier of the Termination Date and the date on which no Warrants
remain outstanding (the “Agreement Termination Date”). On the business day following the Agreement Termination Date,
the Agent shall deliver to the Company any entitlements, if any, held by the Warrant Agent under this Warrant Agreement. The Agent’s
right to be reimbursed for fees, charges and out-of-pocket expenses as provided in this Section 8 shall survive the termination of this
Warrant Agreement.


 


7.7. If any provision of this
Warrant Agreement shall be held illegal, invalid, or unenforceable by any court, this Warrant Agreement shall be construed and enforced
as if such provision had not been contained herein and shall be deemed an Agreement among the parties to it to the full extent permitted
by applicable law.


 


7.8. The Company represents

and sale of the Warrants and the execution, delivery and performance of all transactions contemplated thereby (including this Warrant

the articles of association, bylaws or any similar document of the Company or any indenture, agreement or instrument to which it is a
party or is bound; (c) this Warrant Agreement has been duly executed and delivered by the Company and constitutes the legal, valid, binding
and enforceable obligation of the Company; (d) the Warrants will comply in all material respects with all applicable requirements of law;

shall be governed by and construed in accordance with the laws of the State of New York. All actions and proceedings relating to or arising
from, directly or indirectly, this Warrant Agreement may be litigated in courts located within the City, County and State of New York.
The Company hereby submits to the personal jurisdiction of such courts and consents that any service of process may be made by certified

securities laws.


 


(b) This Warrant Agreement
shall inure to the benefit of and be binding upon the successors and assigns of the parties hereto. This Warrant Agreement may not be
assigned, or otherwise transferred, in whole or in part, by either party without the prior written consent of the other party, which the
other party will not unreasonably withhold, condition or delay; except that (i) consent is not required for an assignment or delegation
of duties by Warrant Agent to any affiliate of Warrant Agent and (ii) any reorganization, merger, consolidation, sale of assets or other
form of business combination by Warrant Agent or the Company shall not be deemed to constitute an assignment of this Warrant Agreement.


 


(c) No provision of this Warrant
Agreement may be amended, modified or waived, except in a written document signed by both parties. The Company and the Warrant Agent may
amend or supplement this Warrant Agreement without the consent of any Holder for the purpose of curing any ambiguity, or curing, correcting
or supplementing any defective provision contained herein or adding or changing any other provisions with respect to matters or questions
arising under this Agreement as the parties may deem necessary or desirable and that the parties determine, in good faith, shall not adversely
affect the interest of the Holders. All other amendments and supplements shall require the vote or written consent of Holders of at least
50.1% of the then outstanding Warrants, provided that adjustments may be made to the Warrant terms and rights in accordance with Section
4 without the consent of the Holders.


  


7.13. Payment of Taxes.
The Company will from time to time promptly pay all taxes and charges that may be imposed upon the Company or the Warrant Agent in respect
of the issuance or delivery of Warrant Shares upon the exercise of Warrants, but the Company may require the Holders to pay any transfer
taxes in respect of the Warrants or such shares. The Warrant Agent may refrain from registering any transfer of Warrants or any delivery
of any Warrant Shares unless or until the persons requesting the registration or issuance shall have paid to the Warrant Agent for the
account of the Company the amount of such tax or charge, if any, or shall have established to the reasonable satisfaction of the Company
and the Warrant Agent that such tax or charge, if any, has been paid.


 


7.14. Resignation
of Warrant Agent.


 


7.14.1. Appointment
of Successor Warrant Agent. The Warrant Agent, or any successor to it hereafter appointed, may resign its duties and be discharged
from all further duties and liabilities hereunder after giving thirty (30) days’ notice in writing to the Company, or such shorter
period of time agreed to by the Company. The Company may terminate the services of the Warrant Agent, or any successor Warrant Agent,
after giving thirty (30) days’ notice in writing to the Warrant Agent or successor Warrant Agent, or such shorter period of time
as agreed. If the office of the Warrant Agent becomes vacant by resignation, termination or incapacity to act or otherwise, the Company
shall appoint in writing a successor Warrant Agent in place of the Warrant Agent. If the Company shall fail to make such appointment within
a period of 30 days after it has been notified in writing of such resignation or incapacity by the Warrant Agent, then the Warrant Agent
or any Holder may apply to any court of competent jurisdiction for the appointment of a successor Warrant Agent at the Company’s
cost. Pending appointment of a successor to such Warrant Agent, either by the Company or by such a court, the duties of the Warrant Agent
shall be carried out by the Company. Any successor Warrant Agent (but not including the initial Warrant Agent), whether appointed by the
Company or by such court, shall be a person organized and existing under the laws of any state of the United States of America, in good
standing, and authorized under such laws to exercise corporate trust powers and subject to supervision or examination by federal or state
authority. After appointment, any successor Warrant Agent shall be vested with all the authority, powers, rights, immunities, duties,
and obligations of its predecessor Warrant Agent with like effect as if originally named as Warrant Agent hereunder, without any further
act or deed, and except for executing and delivering documents as provided in the sentence that follows, the predecessor Warrant Agent
shall have no further duties, obligations, responsibilities or liabilities hereunder, but shall be entitled to all rights that survive
the termination of this Warrant Agreement and the resignation or removal of the Warrant Agent, including but not limited to its right
to indemnity hereunder. If for any reason it becomes necessary or appropriate or at the request of the Company, the predecessor Warrant
Agent shall execute and deliver, at the expense of the Company, an instrument transferring to such successor Warrant Agent all the authority,
powers, and rights of such predecessor Warrant Agent hereunder; and upon request of any successor Warrant Agent the Company shall make,
execute, acknowledge, and deliver any and all instruments in writing for more fully and effectually vesting in and confirming to such
successor Warrant Agent all such authority, powers, rights, immunities, duties, and obligations.


 


7.14.2. Notice of Successor
Warrant Agent. In the event a successor Warrant Agent shall be appointed, the Company shall give notice thereof to the predecessor
Warrant Agent and the transfer agent for the Common Shares not later than the effective date of any such appointment.


 


7.14.3. Merger or Consolidation
of Warrant Agent. Any person into which the Warrant Agent may be merged or converted or with which it may be consolidated or any person
resulting from any merger, conversion or consolidation to which the Warrant Agent shall be a party or any person succeeding to the shareowner
services business of the Warrant Agent or any successor Warrant Agent shall be the successor Warrant Agent under this Warrant Agreement,
without any further act or deed. For purposes of this Warrant Agreement, “person” shall mean any individual, firm, corporation,
partnership, limited liability company, joint venture, association, trust or other entity, and shall include any successor (by merger
or otherwise) thereof or thereto.

7.15. Anti-Money Laundering.


 


Each party to this Agreement
other than the Warrant Agent hereby represents to the Warrant Agent that any account to be opened by, or interest to be held by the Warrant
Agent in connection with this Agreement, for or to the credit of such party, either: (i) is not intended to be used by or on behalf of
any third party; or (ii) is intended to be used by or on behalf of a third party, in which case such party hereto agrees to complete and
execute forthwith a declaration in the Warrant Agent’s prescribed form as to the particulars of such third party.


 


The Warrant Agent shall retain
the right not to act and shall not be liable for refusing to act if, due to a lack of information or for any other reason whatsoever,
the Warrant Agent, in its sole judgment, determines that such act might cause it to be in non-compliance with any applicable anti-money
laundering, anti-terrorist or economic sanctions legislation, regulation or guideline. Further, should the Warrant Agent, in its sole
judgment, determine at any time that its acting under this Agreement has resulted in its being in non-compliance with any applicable anti-money
laundering, anti-terrorist or economic sanctions legislation, regulation or guideline, then it shall have the right to resign on ten (10)
days’ written notice to the other parties to this Agreement, provided (i) that the Warrant Agent's written notice shall describe
the circumstances of such non-compliance; and (ii) that if such circumstances are rectified to the Warrant Agent's satisfaction within
such ten (10) day period, then such resignation shall not be effective.


 


7.16. Compliance with Privacy
Code.


 


The parties acknowledge that
the Warrant Agent may, in the course of providing services hereunder, collect or receive financial and other personal information about
such parties and/or their representatives, as individuals, or about other individuals related to the subject matter hereof, and use such
information for the following purposes:


 


(a)       to
provide the services required under this Agreement and other services that may be requested from time to time;


(b)       to
help the Warrant Agent manage its servicing relationships with such individuals;


(c)       to
meet the Warrant Agent’s legal and regulatory requirements; and


(d)       if
Social Insurance Numbers are collected by the Warrant Agent, to perform tax reporting and to assist in verification of an individual’s
identity for security purposes.


 


Each party acknowledges and
agrees that the Warrant Agent may receive, collect, use and disclose personal information provided to it or acquired by it in the course
of this Agreement for the purposes described above. The Warrant Agent may transfer personal information to other companies in or outside
of the United States that provide data processing and storage or other support in order to facilitate the services it provides.


 


Further, each party agrees
that it shall not provide or cause to be provided to the Warrant Agent any personal information relating to an individual who is not a
party to this Agreement unless that party has assured itself that such individual understands and has consented to the aforementioned
uses and disclosures.
