Warrant
Agent Agreement

 

This
WARRANT AGENT AGREEMENT (this “Warrant Agreement”) dated as of [●], 2022 (the “Issuance Date”)
is between Bruush Oral Care, Inc., a company incorporated under the laws of the Province of British Columbia, Canada (the “Company”),
and Endeavor Trust Corporation, a trust company existing under the laws of the Province of British Columbia (the “Warrant Agent”).

 

WHEREAS,
pursuant to the terms of that certain Underwriting Agreement (“Underwriting Agreement”), dated [●], 2022, by
and among the Company and Aegis Capital Corp., 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 either (A) (1) one share of common stock, no 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”));
or (B) one (1) pre-funded warrant (each, a “Pre-Funded Warrant”) to purchase one (1) Common Share at an exercise price
of $0.001 until such time as the Pre-Funded Warrant is exercised in full subject to adjustment as provided in the Pre-Funded Warrant
and one (1) Warrant (each, a “Closing Pre-Funded Unit”).

 

WHEREAS,
the Company has filed with the Securities and Exchange Commission (the “Commission”) a Registration Statement on Form
F-1(File No. 333-265969) (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 Warrants are exercised, for the Warrant Agent’s services as agent for the Company hereunder, the Company
shall pay to the Warrant Agent such fees as may be separately agreed between the Company and Warrant Agent and the Warrant Agent’s
out of pocket expenses in connection with this Warrant Agreement, including, without limitation, the fees and expenses of the Warrant
Agent’s counsel. While the Warrant Agent endeavors to maintain out-of-pocket charges (both internal and external) at competitive
rates, these charges may 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 date. Delinquent payments are subject to a late payment charge of one and one-half percent (1.5%) per
month commencing 45 days from the invoice date. The Company agrees to reimburse the Warrant Agent for any attorney’s fees and any
other costs associated with collecting 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.

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

act unless it has been furnished with an indemnity reasonably satisfactory to it; (d) may rely on and shall be fully authorized and protected

(e) shall not be liable or responsible for any recital or statement contained in the Registration Statement or any other documents relating

accordance with a proposal included in such application on or after the date specified in such application (which date shall not be less

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,
suffered, or omitted by it hereunder in good faith and in accordance with the advice of such counsel; (i) may perform any of its duties
hereunder either directly or by or through nominees, correspondents, designees, or subagents, and it shall not be liable or responsible

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’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.

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

(b) the offer and sale of the Warrants and the execution, delivery and performance of all transactions contemplated thereby (including

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 Canada 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.

THE
REGISTERED HOLDER OF THIS PURCHASE WARRANT BY ITS ACCEPTANCE HEREOF, AGREES THAT IT WILL NOT SELL, TRANSFER OR ASSIGN THIS PURCHASE WARRANT
EXCEPT AS HEREIN PROVIDED AND THE REGISTERED HOLDER OF THIS PURCHASE WARRANT AGREES THAT IT WILL NOT SELL, TRANSFER, ASSIGN, PLEDGE OR
HYPOTHECATE THIS PURCHASE WARRANT FOR A PERIOD OF ONE HUNDRED EIGHTY DAYS FOLLOWING [●], 2022 (THE “EFFECTIVE DATE”)
TO ANYONE OTHER THAN (I) AEGIS CAPITAL CORP. OR A SELECTED DEALER IN CONNECTION WITH THE OFFERING FOR WHICH THIS PURCHASE WARRANT WAS
ISSUED TO THE UNDERWRITER AS CONSIDERATION (THE “OFFERING”), OR (II) A BONA FIDE OFFICER OR PARTNER OF AEGIS
CAPITAL CORP.

 

THIS
PURCHASE WARRANT IS NOT EXERCISABLE PRIOR TO [●], 2022. VOID AFTER 5:00 P.M., EASTERN TIME, [●], 2027.

 

Common
Stock Purchase Warrant

 

For
the Purchase of [●] Shares of Common Stock

 

of

 

Bruush
Oral Care Inc.

 

1.
Purchase Warrant. THIS CERTIFIES THAT, in consideration of funds duly paid by or on behalf of Aegis Capital Corp. (“Holder”),
as registered owner of this Purchase Warrant, to Bruush Oral Care Inc., an Canadian company (the “Company”),
Holder is entitled, at any time or from time to time beginning [●], 2022 (the “Commencement Date”), and
at or before 5:00 p.m., Eastern time, on [●], 2027 (the “Expiration Date”), but not thereafter, to subscribe
for, purchase and receive, in whole or in part, up to [●] shares of common stock of the Company (the “Common Stock”),
no par value per share (the “Shares”), subject to adjustment as provided in Section 6 hereof. If the Expiration
Date is not a Business Day, then this Purchase Warrant may be exercised on the next succeeding Business Day. During the period ending
on the Expiration Date, the Company agrees not to take any action that would terminate this Purchase Warrant. This Purchase Warrant is
initially exercisable at $[●] per Share; provided, however, that upon the occurrence of any of the events specified
in Section 6 hereof, the rights granted by this Purchase Warrant, including the exercise price per Share and the number of Shares to
be received upon such exercise, shall be adjusted as therein specified. The term “Exercise Price” shall mean
the initial exercise price or the adjusted exercise price, depending on the context, and the term “Business Day”
shall mean a day other than a Saturday, Sunday or any other day which is a federal legal holiday in the United States or any day on which
the Federal Reserve Bank of New York is authorized or required by law or other governmental action to close, provided that the Federal
Reserve Bank of New York shall not be deemed to be authorized or obligated to be closed due to a “shelter in place,” “non-essential
employee” or similar closure of physical location at the direction of any governmental authority if the bank’s electronic
funds transfer systems (including for wire transfers) are open for use by customers on such day.

 

2.
Exercise.

 

2.1
Exercise Form. In order to exercise this Purchase Warrant, the exercise form attached hereto must be duly executed and completed
and delivered to the Company, together with this Purchase Warrant and, subject to Section 2.2, payment of the Exercise Price for the
Shares being purchased payable in cash by wire transfer of immediately available funds to an account designated by the Company or by
certified check or official bank check. If the subscription rights represented hereby shall not be exercised at or before 5:00 p.m.,
Eastern time, on the Expiration Date, this Purchase Warrant shall become and be void without further force or effect, and all rights
represented hereby shall cease and expire. Each exercise hereof shall be irrevocable.

 

    	 

    	 

    

 

2.2
Cashless Exercise. The Company shall use its best efforts to cause the Registration Statement to remain effective with a current
prospectus and to maintain the registration of the shares of Common Stock and of the Warrants under the Exchange Act. If at any time
on or after the Initial Exercise Date, there is no effective registration statement registering, or the prospectus contained therein
is not available for the issuance of the Purchase Warrant to the Holder, then this Warrant may also be exercised, in whole or in part,
at such time by means of a “cashless exercise” in which the Holder shall be entitled to receive the number of Purchase Warrants
equal to the quotient obtained by dividing [(A-B) (X)] by (A), where:

 

	 	(A) =	as applicable: (i) the
    volume-weighted average price, or “VWAP,” defined below, 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 2.1 hereof on a Trading Day prior to the opening of “regular
    trading hours” (as defined in Rule 600(b)(64) of Regulation NMS promulgated under the federal securities laws) on such Trading
    Day, (ii) at the option of the Holder, either (y) the VWAP on the Trading Day immediately preceding the date of the applicable Notice
    of Exercise or (z) the Bid Price of the shares of Common Stock on the principal Trading Market as reported by Bloomberg L.P. as of
    the time of the Holder’s execution of the applicable Notice of Exercise if such Notice of Exercise is executed during “regular
    trading hours” on a Trading Day and is delivered within two (2) hours thereafter (including until two (2) hours after the close
    of “regular trading hours” on a Trading Day) pursuant to Section 2.1 hereof or (iii) the VWAP 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 both executed and delivered
    pursuant to Section 2.1 hereof 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
Purchase Warrants 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 registered characteristics of the Warrants being exercised, and the
holding period of the Warrants being exercised may be tacked on to the holding period of the Purchase Warrants. The Company agrees not
to take any position contrary to this Section 2.2.

 

For
purposes of this Section 2.2, the fair market value of a Share is defined as follows:

 

“VWAP”
means, for any date, the price determined by the first of the following clauses that applies: (a) if the shares of Common Stock then
listed or quoted on a Trading Market, the daily volume weighted average price of the shares of Common Stock for such date (or the nearest
preceding date) on the Trading Market on which the shares of Common Stock are 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 OTCQB or OTCQX is not a Trading Market,
the volume weighted average price of a share of shares of Common Stock for such date (or the nearest preceding date) on the OTCQB or
OTCQX as applicable, (c) if shares of Common Stock are not then listed or quoted for trading on the OTCQB or OTCQX and if prices for
shares of Common Stock are then reported on the OTC Pink Open Market (or a similar organization or agency succeeding to its functions
of reporting prices), the most recent bid price per share of Common Stock so reported, or (d) in all other cases, the fair market value
of the shares of Common Stock as determined by an independent appraiser selected in good faith by the Holder and reasonably acceptable
to the Company, the fees and expenses of which shall be paid by the Company.

 

    	 	2	 

    	 

    

 

2.3
Legend. Each certificate for the securities purchased under this Purchase Warrant shall bear a legend as follows unless such securities
have been registered under the Securities Act of 1933, as amended (the “Act”):

 

The
securities represented by this certificate have not been registered under the Securities Act of 1933, as amended (the “Act”),
or applicable state law. Neither the securities nor any interest therein may be offered for sale, sold or otherwise transferred except
pursuant to an effective registration statement under the Act, or pursuant to an exemption from registration under the Act and applicable
state law which, in the opinion of counsel to Bruush Oral Care Inc., is available.

 

2.4
Resale of Shares. Holder and the Company acknowledge that as of the date hereof the Staff of the Division of Corporation Finance
of the SEC has published Compliance & Disclosure Interpretation 528.04 in the Securities Act Rules section thereof, stating that
the holder of securities issued in connection with a public offering may not rely upon Rule 144 promulgated under the Act to establish
an exemption from registration requirements under Section 4(a)(1) under the Act, but may nonetheless apply Rule 144 constructively for
the resale of such shares in the following manner: (a) provided that six months has elapsed since the last sale under the registration
statement, an underwriter or finder may resell the securities in accordance with the provisions of Rule 144(c), (e), and (f), except
for the notice requirement; (b) a purchaser of the shares from an underwriter receives restricted securities unless the sale is made
with an appropriate, current prospectus, or unless the sale is made pursuant to the conditions contained in (a) above; (c) a purchaser
of the shares from an underwriter who receives restricted securities may include the underwriter’s holding period, provided that
the underwriter or finder is not an affiliate of the issuer; and (d) if an underwriter transfers the shares to its employees, the employees
may tack the firm’s holding period for purposes of Rule 144(d), but they must aggregate sales of the distributed shares with those
of other employees, as well as those of the underwriter or finder, for a six-month period from the date of the transfer to the employees.
Holder and the Company also acknowledge that the Staff of the Division of Corporation Finance of the SEC has advised in various no-action
letters that the holding period associated with securities issued without registration to a service provider commences upon the completion
of the services, which the Company agrees and acknowledges shall be the final closing of the Offering, and that Rule 144(d)(3)(ii) provides
that securities acquired from the issuer solely in exchange for other securities of the same issuer shall be deemed to have been acquired
at the same time as the securities surrendered for conversion (which the Company agrees is the date of the initial issuance of this Purchase
Warrant). In the event that following a reasonably-timed written request by Holder to transfer the Shares in accordance with Compliance
& Disclosure Interpretation 528.04 counsel for the Company in good faith concludes that Compliance & Disclosure Interpretation
528.04 no longer may be relied upon as a result of changes in applicable laws, regulations, or interpretations of the SEC Division of
Corporation Finance, or as a result of judicial interpretations not known by the Company or its counsel on the date hereof (either, a
“Registration Trigger Event”), then the Company shall promptly, and in any event within five (5) Business Days
following the request, provide written notice to Holder of such determination. As a condition to giving such notice, the parties shall
negotiate in good faith a single demand registration right pursuant to an agreement in customary form reasonably acceptable to the parties;
provided that notwithstanding anything to the contrary, the obligations of the Company pursuant to this Section 2 shall terminate on
the fifth anniversary of the commencement of sales of the public offering. In the absence of such conclusion by counsel for the Company,
the Company shall, upon such a request of Holder given no earlier than six months after the final closing of the Offering, instruct its
transfer agent to permit the transfer of such shares in accordance with Compliance & Disclosure Interpretation 528.04, provided that
Holder has provided such documentation as shall be reasonably be requested by the Company to establish compliance with the conditions
of Compliance & Disclosure Interpretation 528.04. Notwithstanding anything to the contrary, pursuant to FINRA Rule 5110(g)(8)(A),
the Holder shall not be entitled to more than one demand registration right hereunder and the duration of the registration rights hereunder
shall not exceed five years from the commencement of sales of the public offering.

 

3.
Transfer.

 

3.1
General Restrictions. The registered Holder of this Purchase Warrant agrees by such Holder’s acceptance hereof, that such
Holder will not: (a) sell, transfer, assign, pledge or hypothecate this Purchase Warrant for a period of one hundred eighty (180) days
following the Effective Date to anyone other than: (i) Holder or an underwriter, placement agent, or a selected dealer participating
in the Offering, or (ii) a bona fide officer or partner of Holder or of any such underwriter, placement agent or selected dealer, in
each case in accordance with FINRA Conduct Rule 5110(g)(1), or (b) for a period of one hundred eighty (180) days following the Effective
Date cause this Purchase Warrant or the securities issuable hereunder to be the subject of any hedging, short sale, derivative, put or
call transaction that would result in the effective economic disposition of this Purchase Warrant or the securities hereunder, except
as provided for in FINRA Rule 5110(g)(2). After 180 days after the Effective Date, transfers to others may be made subject to compliance
with or exemptions from applicable securities laws. In order to make any permitted assignment, the Holder must deliver to the Company
the assignment form attached hereto duly executed and completed, together with the Purchase Warrant and payment of all transfer taxes,
if any, payable in connection therewith. The Company shall within five (5) Business Days transfer this Purchase Warrant on the books
of the Company and shall execute and deliver a new Purchase Warrant or Purchase Warrants of like tenor to the appropriate assignee(s)
expressly evidencing the right to purchase the aggregate number of Shares purchasable hereunder or such portion of such number as shall
be contemplated by any such assignment.

 

    	 	3	 

    	 

    

 

3.2
Restrictions Imposed by the Act. The securities evidenced by this Purchase Warrant shall not be transferred unless and until:
(i) if required by applicable law, the Company has received the opinion of counsel for the Company that the securities may be transferred
pursuant to an exemption from registration under the Act and applicable state securities laws, or (ii) a registration statement or a
post-effective amendment to the Registration Statement relating to the offer and sale of such securities has been filed by the Company
and declared effective by the U.S. Securities and Exchange Commission (the “Commission”) and compliance with
applicable state securities law has been established.

 

4.
Piggyback Registration Rights.

 

4.1
Grant of Right. In the event that there is not an effective registration statement covering the Purchase Warrant or the underlying
Shares, whenever the Company proposes to register any of its shares of Common Stock under the Act (other than (i) a registration effected
solely to implement an employee benefit plan or a transaction to which Rule 145 of the Act is applicable, or (ii) a registration statement
on Form S-4, S-8 or any successor form thereto or another form not available for registering the Shares issuable upon exercise of this
Purchase Warrant for sale to the public, whether for its own account or for the account of one or more stockholders of the Company (a
“Piggyback Registration”), the Company shall give prompt written notice (in any event no later than ten (10)
Business Days prior to the filing of such registration statement) to the Holder of the Company’s intention to effect such a registration
and, subject to the remaining provisions of this Section 4.1, shall include in such registration such number of Shares underlying this
Purchase Warrant (the “Registrable Securities”) that the Holders have (within ten (10) Business Days of the
respective Holder’s receipt of such notice) requested in writing (including such number) to be included within such registration.
If a Piggyback Registration is an underwritten offering and the managing underwriter advises the Company that it has determined in good
faith that marketing factors require a limit on the number of shares of Common Stock to be included in such registration, including all
Shares issuable upon exercise of this Purchase Warrant (if the Holder has elected to include such shares in such Piggyback Registration)
and all other shares of Common Stock proposed to be included in such underwritten offering, the Company shall include in such registration
(i) first, the number of shares of Common Stock that the Company proposes to issue and sell pursuant to such underwritten offering and
(ii) second, the number of shares of Common Stock, if any, requested to be included therein by selling stockholders (including the Holder)
allocated pro rata among all such persons on the basis of the number of shares of Common Stock then owned by each such person. If any
Piggyback Registration is initiated as a primary underwritten offering on behalf of the Company, the Company shall select the investment
banking firm or firms to act as the managing underwriter or underwriters in connection with such offering. Notwithstanding anything to
the contrary, the obligations of the Company pursuant to this Section 4.1 shall terminate on the earlier of (i) the fifth anniversary
of the Effective Date and (ii) the date that Rule 144 would allow the Holder to sell its Registrable Securities during any ninety (90)

Holder and underwriter to do such investigation, upon reasonable advance notice, with respect to information contained in or omitted

shall include access to books, records and properties and opportunities to discuss the business of the Company with its officers and
independent auditors, all to such reasonable extent and at such reasonable times, during normal business hours, as any such Holder shall
reasonably request.

5.1
Partial Exercise or Transfer. Subject to the restrictions in Section 3 hereof, this Purchase Warrant may be exercised or assigned

together with the duly executed exercise or assignment form and funds sufficient to pay any Exercise Price and/or transfer tax if exercised
pursuant to Section 2.1 hereto, the Company shall cause to be delivered to the Holder without charge a new Purchase Warrant of like tenor

as to which this Purchase Warrant has not been exercised or assigned.

 

    	 	5	 

    	 

    

 

5.2
Lost Certificate. Upon receipt by the Company of evidence satisfactory to it of the loss, theft, destruction or mutilation of
this Purchase Warrant and of reasonably satisfactory indemnification or the posting of a bond, determined in the sole discretion of the
Company, the Company shall execute and deliver a new Purchase Warrant of like tenor and date. Any such new Purchase Warrant executed
and delivered as a result of such loss, theft, mutilation or destruction shall constitute a substitute contractual obligation on the
part of the Company.

 

6.
Adjustments.

 

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

 

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

 

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

 

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

 

6.1.4
Changes in Form of Purchase Warrant. This form of Purchase Warrant need not be changed because of any change pursuant to this
Section 6.1, and Purchase Warrants issued after such change may state the same Exercise Price and the same number of Shares as are stated
in the Purchase Warrants initially issued pursuant to this Agreement. The acceptance by any Holder of the issuance of new Purchase Warrants
reflecting a required or permissive change shall not be deemed to waive any rights to an adjustment occurring after the Commencement
Date or the computation thereof.

 

    	 	6	 

    	 

    

  

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

 

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

 

7.
Reservation. The Company shall at all times reserve and keep available out of its authorized Shares, solely for the purpose of
issuance upon exercise of the Purchase Warrants, such number of Shares or other securities, properties or rights as shall be issuable
upon the exercise thereof. The Company covenants and agrees that, upon exercise of the Purchase Warrants and payment of the Exercise
Price therefor, in accordance with the terms hereby, all Shares and other securities issuable upon such exercise shall be duly and validly
issued, fully paid and non-assessable and not subject to preemptive rights of any shareholder.

 

8.
Certain Notice Requirements.

 

8.1
Holder’s Right to Receive Notice. Nothing herein shall be construed as conferring upon the Holder the right to vote or consent
or to receive notice as a shareholder for the election of directors or any other matter, or as having any rights whatsoever as a shareholder
of the Company. If, however, at any time prior to the expiration of the Purchase Warrants and their exercise, any of the events described
in Section 8.2 shall occur, then, in one or more of said events, the Company shall deliver to each Holder a copy of each notice relating
to such events given to the other shareholders of the Company at the same time and in the same manner that such notice is given to the
shareholders.

 

8.2
Events Requiring Notice. The Company shall be required to give the notice described in this Section 8 upon one or more of the
following events: (i) if the Company shall take a record of the holders of its Shares for the purpose of entitling them to receive a
dividend or distribution payable otherwise than in cash, or a cash dividend or distribution payable otherwise than out of retained earnings,
as indicated by the accounting treatment of such dividend or distribution on the books of the Company, or (ii) the Company shall offer
to all the holders of its Shares any additional shares of capital stock of the Company or securities convertible into or exchangeable
for shares of capital stock of the Company, or any option, right or warrant to subscribe therefor.

 

8.3
Notice of Change in Exercise Price. The Company shall, within 3 Business Days after an event requiring a change in the Exercise
Price pursuant to Section 6 hereof, send notice to the Holders of such event and change (“Price Notice”). The
Price Notice shall describe the event causing the change and the method of calculating same.
