COMMON SHARE PURCHASE WARRANT


 


Stellar
biotechnologies, inc.


 





	Warrant Shares: _______	Initial Exercise Date: December [
], 2016
	 	Issue
Date: June [ ], 2016



  


THIS COMMON SHARE 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 six (6) month anniversary of the date hereof (the “Initial Exercise Date”) and on or prior to the
close of business on the fifth (5th) year anniversary of the Initial Exercise Date (the “Termination Date”)
but not thereafter, to subscribe for and purchase from Stellar Biotechnologies, Inc., a British Columbia corporation (the “Company”),
up to ______ shares (as subject to adjustment hereunder, the “Warrant Shares”) of Common Shares. The purchase
price of one share of Common Shares 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 Securities Purchase Agreement
(the “Purchase Agreement”), dated June [30], 2016, among the Company and the purchasers signatory thereto.


 


Section 2.Exercise.


 


a)                 
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 (or e-mail attachment) of the Notice of Exercise in the form annexed hereto.
Within one (1) Trading Day following the date of exercised as aforesaid, the Holder shall deliver the aggregate Exercise Price
for the shares specified in the applicable Notice of Exercise by wire transfer or cashier’s check drawn on a United States
bank unless the cashless exercise procedure specified in Section 2(c) below is specified in the applicable Notice of Exercise.
No ink-original Notice of Exercise shall be required, nor shall any medallion guarantee (or other type of guarantee or notarization)
of any Notice of Exercise 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 Shares under this Warrant shall be $4.50, subject
to adjustment hereunder (the “Exercise Price”).


 


c)                 
Cashless Exercise. If at any time after the six-month anniversary of the Issue Date there is no effective registration
statement registering, or no current prospectus contained is 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 equal to the quotient obtained by dividing [(A-B) (X)] by (A), where:


 


(A) = the
last VWAP immediately preceding the time of delivery of the Notice of Exercise giving rise to the applicable “cashless exercise”,
as set forth in the applicable Notice of Exercise (to clarify, the “last VWAP” will be the last VWAP as calculated
over an entire Trading Day such that, in the event that this Warrant is exercised at a time that the Trading Market is open, the
prior Trading Day’s VWAP shall be used in this calculation);


 


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


 


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


 






     


     


    

 


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


 


“VWAP”
means, for any date, the price determined by the first of the following clauses that applies: (a) if the Common Shares are then
listed or quoted on a Trading Market, the daily volume weighted average price of the Common Shares for such date (or the nearest
preceding date) on the Trading Market on which the Common Shares 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 the Common Shares for such date (or the nearest preceding date) on OTCQB or OTCQX
as applicable, (c) if the Common Shares are not then listed or quoted for trading on OTCQB or OTCQX and if prices for the Common
Shares are then reported in the “Pink Sheets” published 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 Shares so reported, or (d) in
all other cases, the fair market value of a share of Common Shares as determined by an independent appraiser selected in good faith
by the Purchasers of a majority in interest of the Securities then outstanding and reasonably acceptable to the Company, the fees
and expenses of which shall be paid by the Company.


 


 


d)                
Mechanics of Exercise.


 


                                                                                           
i.           
Delivery of Warrant Shares Upon Exercise. The Company shall cause the Warrant Shares purchased hereunder to be transmitted
by the Transfer Agent to the Holder by crediting the account of the Holder’s or its designee’s balance account with
The Depository Trust Company through its Deposit or Withdrawal at Custodian system (“DWAC”) if the Company is
then a participant in such system and either (A) there is an effective registration statement permitting the issuance of the Warrant
Shares to or resale of the Warrant Shares by Holder or (B) the Warrant Shares are eligible for resale by the Holder without volume
or manner-of-sale limitations pursuant to Rule 144, and otherwise by physical delivery of a certificate, registered in the Company’s
share register in the name of the Holder or its designee, for the number of Warrant Shares to which the Holder is entitled pursuant
to such exercise to the address specified by the Holder in the Notice of Exercise by the date that is one (1) Trading Day after
the delivery to the Company of the Notice of Exercise (such date, the “Warrant Share Delivery Date”), provided
that the Company shall not be obligated to deliver Warrant Shares hereunder unless the Company has received the aggregate Exercise
Price on or before the Warrant Share Delivery Date (other than in the case of a Cashless Exercise). Upon delivery of the Notice
of Exercise the Holder shall be deemed for all corporate purposes to have become the holder of record of the Warrant Shares with
respect to which this Warrant has been exercised, irrespective of the date of delivery of the Warrant Shares; provided payment
of the aggregate Exercise Price (other than in the case of a Cashless Exercise) is received within three (3) Trading Days after
the delivery to the Company of the Notice of Exercise. If the Company fails for any reason to deliver to the Holder the Warrant
Shares subject to a Notice of Exercise by the Warrant Share Delivery Date, the Company shall pay to the Holder, in cash, as liquidated
damages and not as a penalty (but without duplication of the remedies provided in Section 4.1(e) of the Purchase Agreement), for
each $1,000 of Warrant Shares subject to such exercise (based on the VWAP of the Common Shares 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 Warrant Share Delivery Date until such Warrant Shares are delivered or Holder rescinds
such exercise. The Company agrees to maintain a transfer agent that is a participant in the FAST program so long as this Warrant
remains outstanding and exercisable.


 






     


     


    

 


                                                                                         
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.


 


                                                                                       
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 in accordance
with the provisions of Section 2(d)(i) above 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, Common Shares 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 Common
Shares 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 Common Shares that would have been issued had the Company timely complied with its exercise and delivery
obligations hereunder. For example, if the Holder purchases Common Shares having a total purchase price of $11,000 to cover a Buy-In
with respect to an attempted exercise of Common Shares 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 Common Shares upon exercise of the Warrant as required pursuant
to the terms hereof. The obligation of the Company to pay compensation for Buy-In under this Section 2(d)(iv) is subject to delivery
by the Holder of the aggregate Exercise Price in accordance with the terms of Section 2(a) herein.


 






     


     


    

 


                                                                                         
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 such Warrant Shares, all of which taxes and expenses
shall be paid by the Company, and such Warrant Shares shall be issued in the name of the Holder or in such name or names as may
be directed by the Holder; provided, however, that in the event that Warrant Shares are to be issued in a name other
than the name of the Holder, this Warrant when surrendered for exercise shall be accompanied by the Assignment Form attached hereto
duly executed by the Holder and the Company may require, as a condition thereto, the payment of a sum sufficient to reimburse it
for any transfer tax incidental thereto. The Company shall pay all Transfer Agent fees required for same-day processing of any
Notice of Exercise and all fees to the Depository Trust Company (or another established clearing corporation performing similar
functions) required for same-day electronic delivery of the Warrant Shares.


 






     


     


    

 


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


 


e)                 
Holder’s Exercise Limitations. The Company shall not effect any exercise of this Warrant, and a Holder shall
not have the right to exercise any portion of this Warrant, pursuant to Section 2 or otherwise, to the extent that after giving
effect to such issuance after exercise as set forth on the applicable Notice of Exercise, the Holder (together with the Holder’s
Affiliates, and any other Persons acting as a group together with the Holder or any of the Holder’s Affiliates (such Persons,
“Attribution Parties”)), would beneficially own in excess of the Beneficial Ownership Limitation (as defined below). 
For purposes of the foregoing sentence, the number of Common Shares beneficially owned by the Holder and its Affiliates and Attribution
Parties shall include the number of Common Shares issuable upon exercise of this Warrant with respect to which such determination
is being made, but shall exclude the number of Common Shares which would be issuable upon (i) exercise of the remaining, nonexercised
portion of this Warrant beneficially owned by the Holder or any of its Affiliates or Attribution Parties and (ii) exercise or conversion
of the unexercised or nonconverted portion of any other securities of the Company (including, without limitation, any other Common
Share Equivalents) subject to a limitation on conversion or exercise analogous to the limitation contained herein beneficially
owned by the Holder or any of its Affiliates or Attribution Parties.  Except as set forth in the preceding sentence, for purposes
of this Section 2(e), beneficial ownership shall be calculated in accordance with Section 13(d) of the Exchange Act and the rules
and regulations promulgated thereunder, it being acknowledged by the Holder that the Company is not representing to the Holder
that such calculation is in compliance with Section 13(d) of the Exchange Act and the Holder is solely responsible for any schedules
required to be filed in accordance therewith. To the extent that the limitation contained in this Section 2(e) applies, the determination
of whether this Warrant is exercisable (in relation to other securities owned by the Holder together with any Affiliates and Attribution
Parties) and of which portion of this Warrant is exercisable shall be in the sole discretion of the Holder, and the submission
of a Notice of Exercise shall be deemed to be the Holder’s determination of whether this Warrant is exercisable (in relation
to other securities owned by the Holder together with any Affiliates and Attribution Parties) and of which portion of this Warrant
is exercisable, in each case subject to the Beneficial Ownership Limitation, and the Company shall have no obligation to verify
or confirm the accuracy of such determination and shall have no liability for exercises of the Warrant that are not in compliance
with the Beneficial Ownership Limitation (other than to the extent that information on the number of outstanding Common Shares
of the Company is provided by the Company and relied upon by the Holders). 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 and the Company shall have no obligation to verify or confirm the accuracy of such determination and shall have no liability
for exercises of the Warrant that are not in compliance with the Beneficial Ownership Limitation. For purposes of this Section
2(e), in determining the number of outstanding Common Shares, a Holder may rely on the number of outstanding Common Shares 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 Common Shares 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 Common Shares then outstanding.  In any case, the number of outstanding
Common Shares shall be determined after giving effect to the conversion or exercise of securities of the Company, including this
Warrant, by the Holder or its Affiliates or Attribution Parties since the date as of which such number of outstanding Common Shares
was reported. The “Beneficial Ownership Limitation” shall be 4.99% of the number of the Common Shares outstanding
immediately after giving effect to the issuance of Common Shares issuable upon exercise of this Warrant. The Holder 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 the Common Shares outstanding immediately after giving effect to the issuance of Common
Shares upon exercise of this Warrant held by the Holder and the provisions of this Section 2(e) shall continue to apply. Any such
increase in the Beneficial Ownership Limitation 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)                 
Share Dividends and Splits. If the Company, at any time while this Warrant is outstanding: (i) pays a share dividend
or otherwise makes a distribution or distributions on its Common Shares or any other equity or equity equivalent securities payable
in Common Shares (which, for avoidance of doubt, shall not include any Common Shares issued by the Company upon exercise of this
Warrant), (ii) subdivides outstanding Common Shares into a larger number of shares, (iii) combines (including by way of reverse
share split) outstanding Common Shares into a smaller number of shares, or (iv) issues by reclassification of the Common Shares
any capital shares 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 Common Shares (excluding treasury shares, if any) outstanding immediately before such event and of which
the denominator shall be the number of Common Shares 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, subject to the limitation on fractional shares in Section 2(d)(v). Any adjustment made pursuant to this Section 3(a)
shall become effective immediately after the record date for the determination of shareholders 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)                 
Call Provision. Subject to the provisions of Section 2(e) and this Section 2(b), if, after two (2) year anniversary
of the Issuance Date, (the “Effective Date”), (i) the VWAP for each of 20 consecutive Trading Days (the “Measurement
Period,” which 20 consecutive Trading Day period shall not have commenced until after the Effective Date) exceeds $13.00
(subject to adjustment for forward and reverse stock splits, recapitalizations, stock dividends and the like after the Initial
Exercise Date), (ii) the average daily volume for such Measurement Period exceeds $100,000 per Trading Day and (iii) the Holder
is not in possession of any information that constitutes, or might constitute, material non-public information which was provided
by the Company or any of its Subsidiaries, or any of their respective officers, directors, employees or agents, then the Company
may, within one (1) Trading Day of the end of such Measurement Period, call for cancellation of all or any portion of this Warrant
for which a Notice of Exercise has not yet been delivered (such right, a “Call”) for consideration equal to
$.001 per Warrant Share. To exercise this right, the Company must deliver to the Holder an irrevocable written notice (a “Call
Notice”), indicating therein the portion of unexercised portion of this Warrant to which such notice applies. If the
conditions set forth below for such Call are satisfied from the period from the date of the Call Notice through and including the
Call Date (as defined below), then any portion of this Warrant subject to such Call Notice for which a Notice of Exercise shall
not have been received by the Call Date will be cancelled at 6:30 p.m. (New York City time) on the tenth Trading Day after the
date the Call Notice is received by the Holder (such date and time, the “Call Date”). Any unexercised portion
of this Warrant to which the Call Notice does not pertain will be unaffected by such Call Notice. In furtherance thereof, the Company
covenants and agrees that it will honor all Notices of Exercise with respect to Warrant Shares subject to a Call Notice that are
tendered through 6:30 p.m. (New York City time) on the Call Date. The parties agree that any Notice of Exercise delivered following
a Call Notice which calls less than all the Warrants shall first reduce to zero the number of Warrant Shares subject to such Call
Notice prior to reducing the remaining Warrant Shares available for purchase under this Warrant. For example, if (A) this Warrant
then permits the Holder to acquire 100 Warrant Shares, (B) a Call Notice pertains to 75 Warrant Shares, and (C) prior to 6:30 p.m.
(New York City time) on the Call Date the Holder tenders a Notice of Exercise in respect of 50 Warrant Shares, then (x) on the
Call Date the right under this Warrant to acquire 25 Warrant Shares will be automatically cancelled, (y) the Company, in the time
and manner required under this Warrant, will have issued and delivered to the Holder 50 Warrant Shares in respect of the exercises
following receipt of the Call Notice, and (z) the Holder may, until the Termination Date, exercise this Warrant for 25 Warrant
Shares (subject to adjustment as herein provided and subject to subsequent Call Notices). Subject again to the provisions of this
Section 2(g), the Company may deliver subsequent Call Notices for any portion of this Warrant for which the Holder shall not have
delivered a Notice of Exercise. Notwithstanding anything to the contrary set forth in this Warrant, the Company may not deliver
a Call Notice or require the cancellation of this Warrant (and any such Call Notice shall be void), unless, from the beginning
of the Measurement Period through the Call Date, (1) the Company shall have honored in accordance with the terms of this Warrant
all Notices of Exercise delivered by 6:30 p.m. (New York City time) on the Call Date, and (2) the Registration Statement shall
be effective as to all Warrant Shares and the prospectus thereunder available for use by the Holder for the resale of all such
Warrant Shares, and (3) the Common Stock shall be listed or quoted for trading on the Trading Market, and (4) there is a sufficient
number of authorized Common Shares for issuance of all Securities under the Transaction Documents, and (5) the issuance of the
shares shall not cause a breach of any provision of Section 2(e) herein. The Company’s right to call the Warrants under this
Section 2(b) shall be exercised ratably among the Holders based on each Holder’s initial purchase of Warrants.


 






     


     


    

 


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 Share Equivalents or rights to purchase shares, warrants, securities or other property pro rata
to the record holders of any class of Common Shares (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 Common Shares 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 Common Shares 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 Common Shares 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).


 


d)                
Pro Rata Distributions. During such time as this Warrant is outstanding, if the Company shall declare or make any
dividend or other distribution of its assets (or rights to acquire its assets) to holders of Common Shares, by way of return of
capital or otherwise (including, without limitation, any distribution of cash, shares or other securities, property or options
by way of a dividend, spin off, reclassification, corporate rearrangement, scheme of arrangement or other similar transaction)
(other than dividends or distributions subject to Section 3(a) herein) (a "Distribution"), at any time after the
issuance of this Warrant, then, in each such case, the Holder shall be entitled to participate in such Distribution to the same
extent that the Holder would have participated therein if the Holder had held the number of Common Shares 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 of which a record is taken for such Distribution, or, if no such record is taken, the date
as of which the record holders of Common Shares are to be determined for the participation in such Distribution (provided,
however, to the extent that the Holder's right to participate in any such Distribution would result in the Holder exceeding
the Beneficial Ownership Limitation, then the Holder shall not be entitled to participate in such Distribution to such extent (or
the beneficial ownership of any Common Shares as a result of such Distribution to such extent) and the portion of such Distribution
shall be held in abeyance for the benefit of the Holder until such time, if ever, as its right thereto would not result in the
Holder exceeding the Beneficial Ownership Limitation).


 






     


     


    

 


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 Shares 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 Shares, (iv) the Company, directly or indirectly, in one or more related transactions effects any reclassification,
reorganization or recapitalization of the Common Shares or any compulsory share exchange pursuant to which the Common Shares are
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 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 Common Shares (not including any Common Shares 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 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 Common Shares 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 Common Shares 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 Shares 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 Shares 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. Notwithstanding
anything to the contrary, in the event of a Fundamental Transaction, concurrently with, the consummation of the Fundamental Transaction,
the Company shall purchase this Warrant from the Holder by paying to the Holder an amount of cash equal to the Black Scholes Value
of the remaining unexercised portion of this Warrant on the date of the consummation of such Fundamental Transaction. The Company
shall be required to give at least 20 days prior written notice of the occurrence of such Fundamental Transaction. “Black
Scholes Value” means the value of this Warrant based on the Black and Scholes Option Pricing Model obtained from the
“OV” function on Bloomberg, L.P. (“Bloomberg”) determined as of the day of consummation of the applicable
Fundamental Transaction for pricing purposes and reflecting (A) a risk-free interest rate corresponding to the U.S. Treasury rate
for a period equal to the time between the date of the public announcement of the applicable Fundamental Transaction and the Termination
Date, (B) an expected volatility equal to the 100 day volatility obtained from the HVT function on Bloomberg as of the Trading
Day immediately following the public announcement of the applicable Fundamental Transaction, (C) the underlying price per share
used in such calculation shall be the sum of the price per share being offered in cash, if any, plus the value of any non-cash
consideration, if any, being offered in such Fundamental Transaction and (D) a remaining option time equal to the time between
the date of the public announcement of the applicable Fundamental Transaction and the Termination Date. 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 customary written agreements 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 capital shares of such Successor Entity (or its parent entity) equivalent to the Common Shares 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 capital shares (but taking into account the relative
value of the Common Shares pursuant to such Fundamental Transaction and the value of such capital shares, such number of capital
shares 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, the Company (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 the Successor Entity 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 Common Shares deemed to be issued and outstanding as of
a given date shall be the sum of the number of Common Shares (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 deliver to the Holder by facsimile or email a notice setting forth the Exercise Price after such adjustment
and any resulting adjustment to the number of Warrant Shares and setting forth a brief statement of the facts requiring such adjustment.


 


                                                                                         
ii.           
Notice to Allow Exercise by Holder. If (A) the Company shall declare a dividend (or any other distribution in whatever
form) on the Common Shares, (B) the Company shall declare a special nonrecurring cash dividend on or a redemption of the Common
Shares, (C) the Company shall authorize the granting to all holders of the Common Shares rights or warrants to subscribe for or
purchase any capital shares of any class or of any rights, (D) the approval of any shareholders of the Company shall be required
in connection with any reclassification of the Common Shares, 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
Shares are converted into other securities, cash or property, or (E) the Company shall authorize the voluntary or involuntary dissolution,
liquidation or winding up of the affairs of the Company, then, in each case, the Company shall cause to be delivered by facsimile
or email to the Holder at its last facsimile number or email address as it shall appear upon the Warrant Register of the Company,
at least 20 calendar days prior to the applicable record or effective date hereinafter specified, a notice stating (x) the date
on which a record is to be taken for the purpose of such dividend, distribution, redemption, rights or warrants, or if a record
is not to be taken, the date as of which the holders of the Common Shares 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 Shares of record shall be entitled to exchange their Common Shares for securities, cash or other property deliverable upon
such reclassification, consolidation, merger, sale, transfer or share exchange; provided that the failure to deliver such notice
or any defect therein or in the delivery thereof shall not affect the validity of the corporate action required to be specified
in such notice. To the extent that any notice provided in this Warrant constitutes, or contains, material, non-public information
regarding the Company or any of the Subsidiaries, the Company shall simultaneously file such notice with the 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 and to the provisions of Section 4.1 of the Purchase Agreement, this Warrant and all rights hereunder (including,
without limitation, any registration rights) are transferable, in whole or in part, upon surrender of this Warrant at the principal
office of the Company or its designated agent, together with a written assignment of this Warrant substantially in the form attached
hereto duly executed by the Holder or its agent or attorney and funds sufficient to pay any transfer taxes payable upon the making
of such transfer. Upon such surrender and, if required, such payment, the Company shall execute and deliver a new Warrant or Warrants
in the name of the assignee or assignees, as applicable, and in the denomination or denominations specified in such instrument
of assignment, and shall issue to the assignor a new Warrant evidencing the portion of this Warrant not so assigned, and this
Warrant shall promptly be cancelled. Notwithstanding anything herein to the contrary, the Holder shall not be required to physically
surrender this Warrant to the Company unless the Holder has assigned this Warrant in full, in which case, the Holder shall surrender
this Warrant to the Company within three (3) Trading Days of the date 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 Issue Date of this Warrant and shall be identical with this Warrant except as to the number of Warrant Shares issuable pursuant
thereto.


 


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


 


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


 






     


     


    

 


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


 


Section 5.Miscellaneous.


 


a)                 
No Rights as Shareholder Until Exercise. This Warrant does not entitle the Holder to any voting rights, dividends
or other rights as a shareholder of the Company prior to the exercise hereof as set forth in Section 2(d)(i), except as expressly
set forth in Section 3(c) and Section 3(d).


 


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 share 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 share
certificate, if mutilated, the Company will make and deliver a new Warrant or share certificate of like tenor and dated as of such
cancellation, in lieu of such Warrant or share 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 Shares 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 Shares may be
listed. The Company covenants that all Warrant Shares which may be issued upon the exercise of the purchase rights represented
by this Warrant will, upon exercise of the purchase rights represented by this Warrant and payment for such Warrant Shares in accordance
herewith, be duly authorized, validly issued, fully paid and nonassessable and free from all taxes, liens and charges created by
the Company in respect of the issue thereof (other than taxes in respect of any transfer occurring contemporaneously with such
issue).


 






     


     


    

 


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


 


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


 


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


 


f)                  
Restrictions. The Holder acknowledges that the Warrant Shares acquired upon the exercise of this Warrant, if not
registered, and the Holder does not utilize cashless exercise following the six-month anniversary of the Issue Date, 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, the Company willfully and knowingly fails to comply with
any provision of this Warrant, which results in any material damages to the Holder, the Company shall pay to the Holder such amounts
as shall be sufficient to cover any costs and expenses including, but not limited to, reasonable attorneys’ fees, including
those of appellate proceedings, incurred by the Holder in collecting any amounts due pursuant hereto or in otherwise enforcing
any of its rights, powers or remedies hereunder.


 






     


     


    

 


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


 


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