WARRANT


DELMAR PHARMACEUTICALS, INC.


 


	Warrant Shares: _______	Initial Exercise Date: _______, 2015
	 	Issue Date: ______, 2015


THIS [CLASS A/CLASS
B] COMMON STOCK PURCHASE WARRANT (the “Warrant”) certifies that, for value received, _____________ or its assigns
(the “Holder”) is entitled, upon the terms and subject to the limitations on exercise and the conditions hereinafter
set forth, at any time on or after the Initial Exercise Date (as set forth above) and on or prior to the close of business on the
[____] year anniversary of the Issue Date (the “Termination Date”) but not thereafter, to subscribe for and
purchase from DelMar Pharmaceuticals, Inc., a Nevada corporation (the “Company”), up to ______ shares (as subject
to adjustment hereunder, the “Warrant Shares”) of Common Stock. The purchase price of one share of Common Stock
under this Warrant shall be equal to the Exercise Price, as defined in Section 2(b).


Section
1.               
Definitions. Capitalized terms used and not otherwise defined herein shall have the meanings set forth in
that certain Underwriting Agreement (the “Underwriting Agreement”), dated _____, 2015, by and between the Company,
the Joint Bookrunners and the Co-Manager.




Section
2.               
Exercise.


a)                 
Exercise of Warrant. Exercise of the purchase rights represented by this Warrant may be made, in whole or
in part, at any time or times on or after the Initial Exercise Date and on or before the Termination Date by delivery to the Company
(or such other office or agency of the Company as it may designate by notice in writing to the registered Holder at the address
of the Holder appearing on the books of the Company) of a duly executed facsimile copy of the Notice of Exercise in the form annexed
hereto and within three (3) Trading Days of the date said Notice of Exercise is delivered to the Company, the Company shall have
received payment of the aggregate Exercise Price of the shares thereby purchased by wire transfer or cashier’s check drawn
on a United States bank or, if available, pursuant to the cashless exercise procedure specified in Section 2(c) below. No ink-original
Notice of Exercise shall be required, nor shall any medallion guarantee (or other type of guarantee or notarization) of any Notice
of Exercise form be required. Notwithstanding anything herein to the contrary, the Holder shall not be required to physically surrender
this Warrant to the Company until the Holder has purchased all of the Warrant Shares available hereunder and the Warrant has been
exercised in full, in which case, the Holder shall surrender this Warrant to the Company for cancellation within three (3) Trading
Days of the date the final Notice of Exercise is delivered to the Company. Partial exercises of this Warrant resulting in purchases
of a portion of the total number of Warrant Shares available hereunder shall have the effect of lowering the outstanding number
of Warrant Shares purchasable hereunder in an amount equal to the applicable number of Warrant Shares purchased. The Holder and
the Company shall maintain records showing the number of Warrant Shares purchased and the date of such purchases. The Company shall
deliver any objection to any Notice of Exercise within one (1) Business Day of receipt of such notice. The Holder and any assignee,
by acceptance of this Warrant, acknowledge and agree that, by reason of the provisions of this paragraph, following the purchase
of a portion of the Warrant Shares hereunder, the number of Warrant Shares available for purchase hereunder at any given time may
be less than the amount stated on the face hereof.

b)                 
Exercise Price. The exercise price per share of the Common Stock under this Warrant shall be $[_____], subject
to adjustment hereunder (the “Exercise Price”).


c)                 
Cashless Exercise. If at any time after the earlier of (i) the one year anniversary of the date of the Underwriting
Agreement and (ii) the completion of the then-applicable holding period required by Rule 144, or any successor provision then in
effect, there is no effective Registration Statement registering, or no current prospectus available for, the resale of the Warrant
Shares by 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 a number of Warrant Shares (it being acknowledged, for the avoidance
of doubt, that such Warrant Shares will be unregistered) equal to the quotient obtained by dividing [(A-B) (X)] by (A), where:


(A) =the
VWAP on the Trading Day immediately preceding the date on which Holder elects to exercise this Warrant by means of a “cashless
exercise,” as set forth in the applicable Notice of Exercise;


(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.


“VWAP”
means, for any date, the price determined by the first of the following clauses that applies: (a) if the Common Stock is then listed
or quoted on a Trading Market, the daily volume weighted average price of the Common Stock for such date (or the nearest preceding
date) on the Trading Market on which the Common Stock is then listed or quoted as reported by Bloomberg L.P. (“Bloomberg”)
(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 the Common Stock is not
then listed or quoted for trading on a Trading Market and if prices for the Common Stock are then reported on the OTC Pink Market
by OTC Markets Group, Inc. (or a similar organization or agency succeeding to its functions of reporting prices), the most recent
bid price per share of the Common Stock so reported, or (c) in all other cases, the fair market value of a share of Common Stock
as determined by an independent appraiser selected in good faith by the Board of Directors of the Company and reasonably acceptable
to the Holder, the fees and expenses of which shall be paid by the Company. For the avoidance of doubt, in the event the Company
does not have an effective registration statement there is no circumstance that would require the Company to net cash settle the
Warrant.

d)                
Mechanics of Exercise.


i.                   
Delivery of Warrant Shares Upon Exercise. Warrant Shares purchased hereunder shall be transmitted by the Transfer
Agent to the Holder by crediting the account of the Holder’s prime broker with The Depository Trust Company through its Deposit
or Withdrawal at Custodian system (“DWAC”) if the Company is then a participant in such system and either (A)
there is an effective registration statement permitting the issuance of the Warrant Shares to or resale of the Warrant Shares by
the Holder or (B) the shares are eligible for resale by the Holder without volume or manner-of-sale limitations or the need for
current public information pursuant to Rule 144, and otherwise by physical delivery to the address specified by the Holder in the
Notice of Exercise by the date that is one (1) Trading Day after the delivery to the Company of the Notice of Exercise (provided,
in the case of an exercise for cash pursuant to Section 2(a) hereof, the Company has received the cash exercise price) (such date,
the “Warrant Share Delivery Date”). The Warrant Shares shall be deemed to have been issued, and Holder or any
other person so designated to be named therein shall be deemed to have become a holder of record of such shares for all purposes,
as of the date the Warrant has been exercised, with payment to the Company of the Exercise Price (or by cashless exercise, if permitted)
and all taxes required to be paid by the Holder, if any, pursuant to Section 2(d)(vi) prior to the issuance of such shares, having
been paid. If the Company fails for any reason to deliver to the Holder the Warrant Shares subject to a Notice of Exercise by the
second Trading Day following the Warrant Share Delivery Date Exercise (provided, in the case of an exercise for cash pursuant to
Section 2(a) hereof, the Company has received the cash exercise price), the Company shall pay to the Holder, in cash, as liquidated
damages and not as a penalty, for each $1,000 of Warrant Shares subject to such exercise (based on the VWAP of the Common Stock
on the date of the applicable Notice of Exercise), $10 per Trading Day (increasing to $20 per Trading Day on the fifth Trading
Day after such liquidated damages begin to accrue) for each Trading Day after such second Trading Day following the Warrant Share
Delivery Date until such Warrant Shares are delivered or Holder rescinds such exercise.


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


iii.               
Rescission Rights. If the Company fails to cause the Transfer Agent to transmit to the Holder the Warrant
Shares pursuant to Section 2(d)(i) by the Warrant Share Delivery Date, then the Holder will have the right to rescind such exercise.


 



    	3



    	 



    




iv.               
Compensation for Buy-In on Failure to Timely Deliver Warrant Shares Upon Exercise. In addition to any other
rights available to the Holder, if the Company fails to cause the Transfer Agent to transmit to the Holder the Warrant Shares pursuant
to an exercise on or before the Warrant Share Delivery Date, and if after such date the Holder is required by its broker to purchase
(in an open market transaction or otherwise) or the Holder’s brokerage firm otherwise purchases, shares of Common Stock to
deliver in satisfaction of a sale by the Holder of the Warrant Shares which the Holder anticipated receiving upon such exercise
(a “Buy-In”), then the Company shall (A) pay in cash to the Holder the amount, if any, by which (x) the Holder’s
total purchase price (including brokerage commissions, if any) for the shares of Common Stock so purchased exceeds (y) the amount
obtained by multiplying (1) the number of Warrant Shares that the Company was required to deliver to the Holder in connection with
the exercise at issue times (2) the price at which the sell order giving rise to such purchase obligation was executed, and (B)
at the option of the Holder, either reinstate the portion of the Warrant and equivalent number of Warrant Shares for which such
exercise was not honored (in which case such exercise shall be deemed rescinded) or deliver to the Holder the number of shares
of Common Stock that would have been issued had the Company timely complied with its exercise and delivery obligations hereunder.
For example, if the Holder purchases Common Stock having a total purchase price of $11,000 to cover a Buy-In with respect to an
attempted exercise of shares of Common Stock with an aggregate sale price giving rise to such purchase obligation of $10,000, under
clause (A) of the immediately preceding sentence the Company shall be required to pay the Holder $1,000. The Holder shall provide
the Company written notice indicating the amounts payable to the Holder in respect of the Buy-In and, upon request of the Company,
evidence of the amount of such loss. Nothing herein shall limit a Holder’s right to pursue any other remedies available to
it hereunder, at law or in equity including, without limitation, a decree of specific performance and/or injunctive relief with
respect to the Company’s failure to timely deliver shares of Common Stock upon exercise of the Warrant as required pursuant
to the terms hereof.


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


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


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

e)                 
Holder’s Exercise Limitations. The Company shall not effect any exercise of this Warrant, and a Holder
shall not have the right to exercise any portion of this Warrant, pursuant to Section 2 or otherwise, to the extent that after
giving effect to such issuance after exercise as set forth on the applicable Notice of Exercise, the Holder (together with the
Holder’s Affiliates, and any other Persons acting as a group together with the Holder or any of the Holder’s Affiliates),
would beneficially own in excess of the Beneficial Ownership Limitation (as defined below). For purposes of the foregoing sentence,
the number of shares of Common Stock beneficially owned by the Holder and its Affiliates shall include the number of shares of
Common Stock issuable upon exercise of this Warrant with respect to which such determination is being made, but shall exclude the
number of shares of Common Stock which would be issuable upon (i) exercise of the remaining, nonexercised portion of this Warrant
beneficially owned by the Holder or any of its Affiliates and (ii) exercise or conversion of the unexercised or nonconverted portion
of any other securities of the Company (including, without limitation, any other Common Stock Equivalents) subject to a limitation
on conversion or exercise analogous to the limitation contained herein beneficially owned by the Holder or any of its Affiliates.
Except as set forth in the preceding sentence, for purposes of this Section 2(e), beneficial ownership shall be calculated in accordance
with Section 13(d) of the Exchange Act and the rules and regulations promulgated thereunder, it being acknowledged by the Holder
that the Company is not representing to the Holder that such calculation is in compliance with Section 13(d) of the Exchange Act
and the Holder is solely responsible for any schedules required to be filed in accordance therewith. To the extent that the limitation
contained in this Section 2(e) applies, the determination of whether this Warrant is exercisable (in relation to other securities
owned by the Holder together with any Affiliates) and of which portion of this Warrant is exercisable shall be in the sole discretion
of the Holder, and the submission of a Notice of Exercise shall be deemed to be the Holder’s determination of whether this
Warrant is exercisable (in relation to other securities owned by the Holder together with any Affiliates) and of which portion
of this Warrant is exercisable, in each case subject to the Beneficial Ownership Limitation, and the Company shall have no obligation
to verify or confirm the accuracy of such determination. In addition, a determination as to any group status as contemplated above
shall be determined in accordance with Section 13(d) of the Exchange Act and the rules and regulations promulgated thereunder.
For purposes of this Section 2(e), in determining the number of outstanding shares of Common Stock, a Holder may rely on the number
of outstanding shares of Common Stock as reflected in (A) the Company’s most recent periodic or annual report filed with
the Commission, as the case may be, (B) a more recent public announcement by the Company or (C) a more recent written notice by
the Company or the Transfer Agent setting forth the number of shares of Common Stock outstanding. Upon the written or oral request
of a Holder, the Company shall within two Trading Days confirm orally and in writing to the Holder the number of shares of Common
Stock then outstanding. In any case, the number of outstanding shares of Common Stock shall be determined after giving effect to
the conversion or exercise of securities of the Company, including this Warrant, by the Holder or its Affiliates since the date
as of which such number of outstanding shares of Common Stock was reported. The “Beneficial Ownership Limitation”
shall be 4.99% of the number of shares of the Common Stock outstanding immediately after giving effect to the issuance of shares
of Common Stock issuable upon exercise of this Warrant. The Holder, upon not less than 61 days’ prior notice to the Company,
may increase or decrease the Beneficial Ownership Limitation provisions of this Section 2(e), provided that the Beneficial Ownership
Limitation in no event exceeds 9.99% of the number of shares of the Common Stock outstanding immediately after giving effect to
the issuance of shares of Common Stock upon exercise of this Warrant held by the Holder and the provisions of this Section 2(e)
shall continue to apply. Any such increase or decrease will not be effective until the 61st day after such notice is
delivered to the Company. The provisions of this paragraph shall be construed and implemented in a manner otherwise than in strict
conformity with the terms of this Section 2(e) to correct this paragraph (or any portion hereof) which may be defective or inconsistent
with the intended Beneficial Ownership Limitation herein contained or to make changes or supplements necessary or desirable to
properly give effect to such limitation. The limitations contained in this paragraph shall apply to a successor holder of this
Warrant.

Section
3.               
Certain Adjustments.


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


b)                 
[RESERVED]


c)                 
Subsequent Rights Offerings. In addition to any adjustments pursuant to Section 3(a) above, if at any time
the Company grants, issues or sells any Common Stock Equivalents or rights to purchase stock, warrants, securities or other property
pro rata to the record holders of any class of shares of Common Stock (the “Purchase Rights”), then the Holder
will be entitled to acquire, upon the terms applicable to such Purchase Rights, the aggregate Purchase Rights which the Holder
could have acquired if the Holder had held the number of shares of Common Stock acquirable upon complete exercise of this Warrant
(without regard to any limitations on exercise hereof, including without limitation, the Beneficial Ownership Limitation) immediately
before the date on which a record is taken for the grant, issuance or sale of such Purchase Rights, or, if no such record is taken,
the date as of which the record holders of shares of Common Stock are to be determined for the grant, issue or sale of such Purchase
Rights (provided, however, to the extent that the Holder’s right to participate in any such Purchase Right would result in
the Holder exceeding the Beneficial Ownership Limitation, then the Holder shall not be entitled to participate in such Purchase
Right to such extent (or beneficial ownership of such shares of Common Stock as a result of such Purchase Right to such extent)
and such Purchase Right to such extent shall be held in abeyance for the Holder until such time, if ever, as its right thereto
would not result in the Holder exceeding the Beneficial Ownership Limitation).


 



    	6



    	 



    




d)                
Reserved.


e)                 
Fundamental Transaction. If, at any time while this Warrant is outstanding, (i) the Company, directly or indirectly,
in one or more related transactions effects any merger or consolidation of the Company with or into another Person, (ii) the Company,
directly or indirectly, effects any sale, lease, license, assignment, transfer, conveyance or other disposition of all or substantially
all of its assets in one or a series of related transactions, (iii) any, direct or indirect, purchase offer, tender offer or exchange
offer (whether by the Company or another Person) is completed pursuant to which holders of Common Stock are permitted to sell,
tender or exchange their shares for other securities, cash or property and has been accepted by the holders of 50% or more of the
outstanding Common Stock, (iv) the Company, directly or indirectly, in one or more related transactions effects any reclassification,
reorganization or recapitalization of the Common Stock or any compulsory share exchange pursuant to which the Common Stock is effectively
converted into or exchanged for other securities, cash or property, or (v) the Company, directly or indirectly, in one or more
related transactions consummates a stock or share purchase agreement or other business combination (including, without limitation,
a reorganization, recapitalization, spin-off or scheme of arrangement) with another Person or group of Persons whereby such other
Person or group acquires more than 50% of the outstanding shares of Common Stock (not including any shares of Common Stock held
by the other Person or other Persons making or party to, or associated or affiliated with the other Persons making or party to,
such stock or share purchase agreement or other business combination) (each a “Fundamental Transaction”), then,
upon any subsequent exercise of this Warrant, the Holder shall have the right to receive, for each Warrant Share that would have
been issuable upon such exercise immediately prior to the occurrence of such Fundamental Transaction, at the option of the Holder
(without regard to any limitation in Section 2(e) on the exercise of this Warrant), the number of shares of Common Stock of the
successor or acquiring corporation or of the Company, if it is the surviving corporation, and any additional consideration (the
“Alternate Consideration”) receivable as a result of such Fundamental Transaction by a holder of the number
of shares of Common Stock for which this Warrant is exercisable immediately prior to such Fundamental Transaction (without regard
to any limitation in Section 2(e) on the exercise of this Warrant). For purposes of any such exercise, the determination of the
Exercise Price shall be appropriately adjusted to apply to such Alternate Consideration based on the amount of Alternate Consideration
issuable in respect of one share of Common Stock in such Fundamental Transaction, and the Company shall apportion the Exercise
Price among the Alternate Consideration in a reasonable manner reflecting the relative value of any different components of the
Alternate Consideration. If holders of Common Stock are given any choice as to the securities, cash or property to be received
in a Fundamental Transaction, then the Holder shall be given the same choice as to the Alternate Consideration it receives upon
any exercise of this Warrant following such Fundamental Transaction. The Company shall cause any successor entity in a Fundamental
Transaction in which the Company is not the survivor (the “Successor Entity”) to assume in writing all of the
obligations of the Company under this Warrant and the other Transaction Documents in accordance with the provisions of this Section
3(e) pursuant to written agreements in form and substance reasonably satisfactory to the Holder and approved by the Holder (without
unreasonable delay) prior to such Fundamental Transaction and shall, at the option of the Holder, deliver to the Holder in exchange
for this Warrant a security of the Successor Entity evidenced by a written instrument substantially similar in form and substance
to this Warrant which is exercisable for a corresponding number of shares of capital stock of such Successor Entity (or its parent
entity) equivalent to the shares of Common Stock acquirable and receivable upon exercise of this Warrant (without regard to any
limitations on the exercise of this Warrant) prior to such Fundamental Transaction, and with an exercise price which applies the
exercise price hereunder to such shares of capital stock (but taking into account the relative value of the shares of Common Stock
pursuant to such Fundamental Transaction and the value of such shares of capital stock, such number of shares of capital stock
and such exercise price being for the purpose of protecting the economic value of this Warrant immediately prior to the consummation
of such Fundamental Transaction), and which is reasonably satisfactory in form and substance to the Holder. Upon the occurrence
of any such Fundamental Transaction, the Successor Entity shall succeed to, and be substituted for (so that from and after the
date of such Fundamental Transaction, the provisions of this Warrant and the other Transaction Documents referring to the “Company”
shall refer instead to the Successor Entity), and may exercise every right and power of the Company and shall assume all of the
obligations of the Company under this Warrant and the other Transaction Documents with the same effect as if such Successor Entity
had been named as the Company herein.

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


g)                 
Notice to Holder.


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


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

Section
4.               
Transfer of Warrant.


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


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


 



    	9



    	 



    




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


d)                
Transfer. This Warrant may be offered for sale, sold, transferred or assigned without the consent of the Company.
Notwithstanding any other provision herein, the Company shall use its commercially reasonable efforts to ensure that any Common
Shares issuable in connection with or upon exercise of the Warrants shall be eligible for sale without any restriction or limitation
in the United States. Neither the Warrants nor the Warrant Shares shall bear any legend restricting the transfer or trading of
any such securities.


Section
5.               
Miscellaneous.


a)                 
No Rights as Stockholder Until Exercise. This Warrant does not entitle the Holder to any voting rights, dividends
or other rights as a stockholder of the Company prior to the exercise hereof, except as expressly set forth in Section 3.


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


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


d)                
Authorized Shares.


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

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


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


e)                 
Governing Law. All questions concerning the construction, validity, enforcement and interpretation of this
Warrant shall be governed by and construed and enforced in accordance with the internal laws of the State of New York, without
regard to the principles of conflicts of law thereof. Each party agrees that all legal proceedings concerning the interpretations,
enforcement and defense of the transactions contemplated by this Warrant (whether brought against a party hereto or its respective
affiliates, directors, officers, shareholders, partners, members, employees or agents) shall be commenced exclusively in the state
and federal courts sitting in the City of New York. Each party hereby irrevocably submits to the exclusive jurisdiction of the
state and federal courts sitting in the City of New York, Borough of Manhattan for the adjudication of any dispute hereunder or
in connection herewith or with any transaction contemplated hereby or discussed herein (including with respect to the enforcement
of this Warrant), and hereby irrevocably waives, and agrees not to assert in any action, suit or proceeding, any claim that it
is not personally subject to the jurisdiction of any such court, that such suit, action or proceeding is improper or is an inconvenient
venue for such proceeding. Each party hereby irrevocably waives personal service of process and consents to process being served
in any such suit, action or proceeding by mailing a copy thereof via overnight delivery (with evidence of delivery) to such party
at the address in effect for notices to it under this Warrant and agrees that such service shall constitute good and sufficient
service of process and notice thereof. Nothing contained herein shall be deemed to limit in any way any right to serve process
in any other manner permitted by law. If either party shall commence an action or proceeding to enforce any provisions of this
Warrant, then the prevailing party in such action, suit or proceeding shall be reimbursed by the other party for its reasonable
attorneys’ fees and other costs and expenses incurred with the investigation, preparation and prosecution of such action
or proceeding.

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


g)                 
Nonwaiver and Expenses. No course of dealing or any delay or failure to exercise any right hereunder on the
part of Holder shall operate as a waiver of such right or otherwise prejudice the Holder’s rights, powers or remedies, notwithstanding
the fact that all rights hereunder terminate on the Termination Date. If the Company willfully and knowingly fails to comply with
any provision of this Warrant, which results in any material damages to the Holder, the Company shall pay to the Holder such amounts
as shall be sufficient to cover any costs and expenses including, but not limited to, reasonable attorneys’ fees, including
those of appellate proceedings, incurred by the Holder in collecting any amounts due pursuant hereto or in otherwise enforcing
any of its rights, powers or remedies hereunder.


h)                 
Notices. Any and all notices or other communications or deliveries to be provided by the Holders hereunder
including, without limitation, any Notice of Exercise, shall be in writing and delivered by email, personally, by facsimile, or
sent by a nationally recognized overnight courier service, addressed to the Company, at the principal offices of the Company. Any
and all notices or other communications or deliveries to be provided by the Company hereunder shall be in writing and delivered
by email, personally, by facsimile, or sent by a nationally recognized overnight courier service addressed to each Holder at the
facsimile number or address of such Holder appearing on the books of the Company, or if no such facsimile number or address appears
on the books of the Company, at the principal place of business of such Holder, as set forth in the books of the Company. Any notice
or other communication or deliveries hereunder shall be deemed given and effective on the earliest of (i) the date of transmission,
if such notice or communication is delivered via facsimile at the facsimile number set forth in this Section prior to 5:30 p.m.
(New York City time) on any date, (ii) the next Trading Day after the date of transmission, if such notice or communication is
delivered via facsimile at the facsimile number set forth in this Section on a day that is not a Trading Day or later than 5:30
p.m. (New York City time) on any Trading Day, (iii) the second Trading Day following the date of mailing, if sent by U.S. nationally
recognized overnight courier service, or (iv) upon actual receipt by the party to whom such notice is required to be given.


The Company shall
provide the Holder with prompt written notice of all actions taken pursuant to this Warrant, including in reasonable detail a description
of such action and the reason therefor. Without limiting the generality of the foregoing, the Company will give written notice
to the Holder (i) immediately upon any adjustment of the Exercise Price, setting forth in reasonable detail, and certifying, the
calculation of such adjustment, (ii) at least fifteen (15) days prior to the date on which the Company closes its books or takes
a record (A) with respect to any dividend or distribution upon the Common Shares, (B) with respect to any grants, issuances or
sales of any options, convertible securities or rights to purchase stock, warrants, securities or other property to holders of
Common Shares or (C) for determining rights to vote with respect to any Fundamental Transaction, dissolution or liquidation and
(iii) at least ten (10) Trading Days prior to the consummation of any Fundamental Transaction; provided in each case that
such information shall be made known to the public prior to or in conjunction with such notice being provided to the Holder. It
is expressly understood and agreed that the time of execution specified by the Holder in each Notice of Exercise shall be definitive
and may not be disputed or challenged by the Company.

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


j)                   
Remedies. The Holder, in addition to being entitled to exercise all rights granted by law, including recovery
of damages, will be entitled to specific performance of its rights under this Warrant. The Company agrees that monetary damages
would not be adequate compensation for any loss incurred by reason of a breach by it of the provisions of this Warrant and hereby
agrees to waive and not to assert the defense in any action for specific performance that a remedy at law would be adequate.


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


l)                   
Amendment. This Warrant may be modified or amended or the provisions hereof waived with the written consent
of the Company and the Holder.


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


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