Section

a)
Exercise of Warrant. Exercise of the purchase rights represented by this Warrant may be made, in whole or in part, at any
time or times on or after the Initial Exercise Date and on or before the Termination Date by delivery to the Company of a duly
executed facsimile copy or PDF copy submitted by e-mail (or e-mail attachment) of the Notice of Exercise in the form annexed hereto
(the “Notice of Exercise”). Within the earlier of (i) two (2) Trading Days and (ii) the number of Trading Days
comprising the Standard Settlement Period (as defined in Section 2(d)(i) herein) following the date of exercise as aforesaid,
the Holder shall deliver the aggregate Exercise Price for the Warrant Shares specified in the applicable Notice of Exercise by
wire transfer or cashier’s check drawn on a United States bank unless the cashless exercise procedure specified in Section
2(c) below is specified in the applicable Notice of Exercise. No ink-original Notice of Exercise shall be required, nor shall
any medallion guarantee (or other type of guarantee or notarization) of any Notice of Exercise be required. Notwithstanding anything
herein to the contrary, the Holder shall not be required to physically surrender this Warrant to the Company until the Holder
has purchased all of the Warrant Shares available hereunder and the Warrant has been exercised in full, in which case, the Holder
shall surrender this Warrant to the Company for cancellation within three (3) Trading Days of the date on which the final Notice
of Exercise is delivered to the Company. Partial exercises of this Warrant resulting in purchases of a portion of the total number
of Warrant Shares available hereunder shall have the effect of lowering the outstanding number of Warrant Shares purchasable hereunder
in an amount equal to the applicable number of Warrant Shares purchased. The Holder and the Company shall maintain records showing
the number of Warrant Shares purchased and the date of such purchases. The Company shall deliver any objection to any Notice of
Exercise within one (1) Trading 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 Common Share under this Warrant shall be $[        2,
subject to adjustment hereunder (the “Exercise Price”).


 


c)
Cashless Exercise. If at the time of exercise hereof, 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 equal to the quotient obtained by dividing [(A-B) (X)] by (A), where:


 


(A)
= as applicable: (i) the VWAP on the Trading Day immediately preceding the date of the applicable Notice of Exercise if such Notice
of Exercise is (1) both executed and delivered pursuant to Section 2(a) hereof on a day that is not a Trading Day or (2) both
executed and delivered pursuant to Section 2(a) hereof on a Trading Day prior to the opening of “regular trading hours”
(as defined in Rule 600(b)(68) of Regulation NMS promulgated under the federal securities laws) on such Trading Day, (ii) at the
option of the Holder, either (y) the VWAP on the Trading Day immediately preceding the date of the applicable Notice of Exercise
or (z) the Bid Price of the Common Shares on the principal Trading Market as reported by Bloomberg L.P. as of the time of the
Holder’s execution of the applicable Notice of Exercise if such Notice of Exercise is executed during “regular trading
hours” on a Trading Day and is delivered within two (2) hours thereafter (including until two (2) hours after the close
of “regular trading hours” on a Trading Day) pursuant to Section 2(a) hereof or (iii) the VWAP on the date of the
applicable Notice of Exercise if the date of such Notice of Exercise is a Trading Day and such Notice of Exercise is both executed
and delivered pursuant to Section 2(a) hereof after the close of “regular trading hours” on such Trading Day;


 


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


 


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


 


If
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 registered characteristics of the Warrants being exercised. The Company
agrees not to take any position contrary to this Section 2(c).

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 the Holder or (B) this Warrant is being exercised via cashless exercise,
and otherwise by physical delivery of a certificate, registered in the Company’s share register in the name of the Holder
or its designee, for the number of Warrant Shares to which the Holder is entitled pursuant to such exercise to the address specified
by the Holder in the Notice of Exercise by the date that is the earlier of (i) the earlier of (A) two (2) Trading Days after the
delivery to the Company of the Notice of Exercise and (B) one (1) Trading Day after delivery of the aggregate Exercise Price to
the Company and (ii) the number of Trading Days comprising the Standard Settlement Period after the delivery to the Company of
the Notice of Exercise (such date, the “Warrant Share Delivery Date”). Upon delivery of the Notice of Exercise,
the Holder shall be deemed for all corporate purposes to have become the holder of record of the Warrant Shares with respect to
which this Warrant has been exercised, irrespective of the date of delivery of the Warrant Shares, provided that payment of the
aggregate Exercise Price (other than in the case of a cashless exercise) is received within the earlier of (i) two (2) Trading
Days and (ii) the number of Trading Days comprising the Standard Settlement Period following delivery 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, for each $1,000
of Warrant Shares subject to such exercise (based on the VWAP of the Common Share 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. As used herein, “Standard Settlement Period” means the standard settlement period, expressed
in a number of Trading Days, on the Company’s primary Trading Market with respect to the Common Shares as in effect on the
date of delivery of the Notice of Exercise. Notwithstanding the foregoing, with respect to any Notice(s) of Exercise delivered
on or prior to 12:00 p.m. (New York City time) on the Initial Exercise Date, which may be delivered at any time after the time
of the pricing of the offering pursuant to the Registration Statement, the Company agrees to deliver the Warrant Shares subject
to such notice(s) by 4:00 p.m. (New York City time) on the Initial Exercise Date and the Initial Exercise Date shall be the Warrant
Share Delivery Date for purposes hereunder.

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 Share 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.


 




    	6



    	 



    

 


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 this Warrant that are in non-compliance with the Beneficial Ownership Limitation; provided, however, if the non-compliance
with the Beneficial Ownership Limitation is due to receipt of inaccurate information from the Company, the Company shall be liable
for exercises of this Warrant that are in non-compliance with the Beneficial Ownership Limitation. 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 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 one Trading Day 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 Common Shares outstanding immediately after giving effect to the
issuance of Common Shares issuable upon exercise of this Warrant. The Holder, upon 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 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 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 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 Common Share any
share capital 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. 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)
[Reserved.]


 


c)
Subsequent Rights Offerings. In addition to any adjustments pursuant to Section 3(a) above, during such time as this Warrant
is outstanding the Company grants, issues or sells any Common Share Equivalents or rights to purchase share, 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, that, 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
(other than cash) 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 share or other securities, property or options
by way of a dividend, spin off, reclassification, corporate rearrangement, scheme of arrangement or other similar transaction)
(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, that, 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 in 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). To the extent that this Warrant has not been partially or completely exercised at the time of such Distribution,
such portion of the Distribution shall be held in abeyance for the benefit of the Holder until the Holder has exercised this Warrant.

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
(and all of its subsidiaries, taken as a whole), 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 stock or share
purchase agreement or other business combination (including, without limitation, a reorganization, recapitalization, spin-off,
merger 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 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 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) or Section 2(f) 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 Common Share 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, the Company or any Successor
Entity (as defined below) shall, at the Holder’s option, exercisable at any time concurrently with, or within 30 days after,
the consummation of the Fundamental Transaction (or, if later, the date of the public announcement of the applicable Fundamental
Transaction), purchase this Warrant from the Holder by paying to the Holder an amount of cash equal to the Black Scholes Value
(as defined below) of the remaining unexercised portion of this Warrant on the date of the consummation of such Fundamental Transaction;
provided, however, that, if the Fundamental Transaction is not within the Company’s control, including not
approved by the Company’s Board of Directors, Holder shall only be entitled to receive from the Company or any Successor
Entity, as of the date of consummation of such Fundamental Transaction, the same type or form of consideration (and in the same
proportion), at the Black Scholes Value of the unexercised portion of this Warrant, that is being offered and paid to the holders
of Common Shares in connection with the Fundamental Transaction, whether that consideration be in the form of cash, share or any
combination thereof, or whether the holders of Common Shares are given the choice to receive from among alternative forms of consideration
in connection with the Fundamental Transaction; provided, further, that if holders of Common Shares of the Company are not offered
or paid any consideration in such Fundamental Transaction, such holders of Common Shares will be deemed to have received common
share of the Successor Entity (which Entity may be the Company following such Fundamental Transaction) in such Fundamental Transaction.
“Black Scholes Value” means the value of this Warrant based on the Black-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 greater of 100% and the 100 day volatility obtained from the
HVT function on Bloomberg (determined utilizing a 365 day annualization factor) 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 greater of (i) 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 (ii) the greater of (x) the last VWAP immediately prior to the public
announcement of such Fundamental Transaction and (y) the last VWAP immediately prior to the consummation of 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 payment of the Black Scholes Value will be made by wire transfer of immediately available funds
(or such other consideration) within five Business Days of the Holder’s election (or, if later, on the effective date of
the 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 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 share capital 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 share capital (but taking into account the relative
value of the Common Shares pursuant to such Fundamental Transaction and the value of such share capital, such number of share
capital 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 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 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.

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 shares of any class or of any rights (excluding any granting or issuance of rights to all of the Company’s
shareholders pursuant to a shareholder rights plan), (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 on a Form
6-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.

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


 


Section
4. Transfer of Warrant.


 


a)
Transferability. Pursuant to FINRA Rule 5110(g)(1), neither this Warrant nor any Warrant Shares issued upon exercise of
this Warrant shall be sold, transferred, assigned, pledged or hypothecated, or be the subject of any hedging, short sale, derivative,
put or call transaction that would result in the effective economic disposition of the securities by any person for a period of
180 days immediately following the date of effectiveness or commencement of sales of the offering pursuant to which this Warrant
is being issued, except the transfer of any security:


 


i.
by operation of law or by reason of reorganization of the Company;


 


ii.
to any FINRA member firm participating in the offering and the officers and partners thereof, if all securities so transferred
remain subject to the lock-up restriction in this Section 4(a) for the remainder of the time period;


 


iii.
if the aggregate amount of securities of the Company held by the underwriter and related persons do not exceed 1% of the securities
being offered;


 


iv.
that is beneficially owned on a pro-rata basis by all equity owners of an investment fund, provided that no participating member
manages or otherwise directs investments by the fund, and participating members in the aggregate do not own more than 10% of the
equity in the fund; or


 


v.
the exercise or conversion of any security, if all securities received remain subject to the lock-up restriction in this Section
4(a) for the remainder of the time period.


 


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

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


 


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 written notice to the contrary.


 


Section
5. Miscellaneous.


 


a)
No Rights as Shareholder Until Exercise; No New Cash Settlement. 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. Without limiting any rights of a Holder to receive Warrant Shares on a “cashless
exercise” pursuant to Section 2(c) or to receive cash payments pursuant to Section 2(d)(i) and Section 2(d)(iv) herein,
in no event shall the Company be required to net cash settle an exercise of this Warrant.


 


b)
Loss, Theft, Destruction or Mutilation of Warrant. The Company covenants that upon receipt by the Company of evidence reasonably
satisfactory to it of the loss, theft, destruction or mutilation of this Warrant or any 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.


 




    	12



    	 



    

 


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 Trading Day, then, such action may be taken or such right may be exercised on the next
succeeding Trading Day.


 


d)
Authorized Shares.


 


The
Company hereby represents and warrants to the Holder that its articles do not provide for any limit on the number of Common Shares
that may be issued by the Company. 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.


 




    	13



    	 



    

 


e)
Jurisdiction. 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 their 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, and hereby irrevocably waives, and agrees not to assert in any
suit, action 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 registered
or certified mail or 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, suit or proceeding to enforce any provisions of this Warrant, the prevailing party in such action,
suit or proceeding shall be reimbursed by the other party for their 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 and applicable Canadian securities laws.


 


g)
Nonwaiver and Expenses. No course of dealing or any delay or failure to exercise any right hereunder on the part of Holder
shall operate as a waiver of such right or otherwise prejudice the Holder’s rights, powers or remedies. Without limiting
any other provision of this Warrant, 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 personally, by facsimile or e-mail, or sent by a nationally
recognized overnight courier service, addressed to the Company, at [__], Attention: Chief Financial Officer, facsimile number:

purposes by notice to the Holders. Any and all notices or other communications or deliveries to be provided by the Company hereunder
shall be in writing and delivered personally, by facsimile or e-mail, or sent by a nationally recognized overnight courier service
addressed to each Holder at the facsimile number, e-mail address or address of such Holder appearing on 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 time
of transmission, if such notice or communication is delivered via facsimile at the facsimile number or via e-mail at the e-mail
address 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 time
of transmission, if such notice or communication is delivered via facsimile at the facsimile number or via e-mail at the e-mail
address 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. To the extent that any notice provided hereunder
constitutes, or contains, material, non-public information regarding the Company or any Subsidiaries, the Company shall simultaneously
file such notice with the Commission pursuant to a Form 6-K.

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 may 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 and with the approval of the Toronto Stock Exchange (the “TSX”), provided the Company shall
at such time be an issuer listed on the TSX and to the extent such approval is required under TSX rules and policies at such time.
A Holder may also waive in writing a provision hereof in its favor or for its benefit. No consideration shall be offered or paid
to the Holder to amend or consent to a waiver or modification of any provision of this Warrant unless the same consideration is
also offered to all of the holders of the other Warrants.








 


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.
