COMMON
STOCK PURCHASE WARRANT

 

Surna
Inc.

 

	Warrant
    Shares: 28,947,368	 	Initial
    Exercise Date: September 28, 2021

 

THIS
COMMON STOCK PURCHASE WARRANT (the “Warrant”) certifies that, for value received, EVERGREEN CAPITAL MANAGEMENT LLC,
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 date hereof (the “Initial Exercise Date”) and on or prior to 5:00
p.m., New York City Time, on September 28, 2024 (the “Termination Date”) but not thereafter, to subscribe for and
purchase from Surna Inc., a Nevada corporation (the “Company”), up to 28,947,368 shares (as subject to adjustment
hereunder, the “Warrant Shares”) of Common Stock. The purchase price of one share of Common Stock under this Warrant
shall be equal to the Exercise Price, as defined in Section 1(b).

 

This
Warrant is being issued pursuant to that certain Securities Purchase Agreement dated as of September 28, 2021 between the Holder and
the Company (the “Securities Purchase Agreement”). In addition to the terms defined elsewhere in this Warrant, capitalized
terms that are not otherwise defined herein have the meanings given to such terms in the Securities Purchase Agreement.

 

1.  Exercise.

 

(a) Exercise
of Warrant. Exercise of the purchase rights represented by this Warrant may be made, in whole or in part, at any time or times
on or after the Initial Exercise Date and on or before the Termination Date by delivery to the Company (or such other office or
agency of the Company as it may designate by notice in writing to the registered Holder at the address of the Holder appearing on
the books of the Company) of a duly executed facsimile copy (or e-mail attachment) of the Notice of Exercise in the form annexed
hereto and within five (5) Trading Days of the date said Notice of Exercise is delivered to the Company, the Company shall have
received payment of the aggregate Exercise Price of the shares thereby purchased by wire transfer or cashier’s check drawn on
a United States bank or, if available, pursuant to the cashless exercise procedure specified in Section 1(c) below. No ink-original
Notice of Exercise shall be required, nor shall any medallion guarantee (or other type of guarantee or notarization) of any Notice
of Exercise form be required. Notwithstanding anything herein to the contrary, the Holder shall not be required to physically
surrender this Warrant to the Company until the Holder has purchased all of the Warrant Shares available hereunder and the Warrant
has been exercised in full, in which case, the Holder shall surrender this Warrant to the Company for cancellation within five (5)
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 three (3) Business Day of receipt of such notice. The Holder and any
assignee, by acceptance of this Warrant, acknowledge and agree that, by reason of the provisions of this paragraph, following the
purchase of a portion of the Warrant Shares hereunder, the number of Warrant Shares available for purchase hereunder at any given
time may be less than the amount stated on the face hereof.

 

    	 

    	 

    

 

(b) Exercise
Price. The exercise price per share of the Common Stock under this Warrant shall initially be $0.063, subject to adjustment
hereunder (the “Exercise Price”).

 

(c) Cashless
Exercise. If at any time after the six-month anniversary of the Initial Exercise Date, 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
only 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
                                            VWAP on the Trading Day immediately preceding the date on which Holder elects to exercise
                                            this Warrant by means of a “cashless exercise,” as set forth in the applicable
                                            Notice of Exercise;
	 	 
	B
                                            =	the
                                            Exercise Price of this Warrant, as adjusted hereunder; and
	 	 
	X
                                            =	the
                                            number of Warrant Shares that would be issuable upon exercise of this Warrant in accordance
                                            with the terms of this Warrant if such exercise were by means of a cash exercise rather than
                                            a cashless exercise.

 

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 Warrants
being exercised may be tacked on to the holding period of the Warrant Shares. The Company agrees not to take any position contrary to
this Section 2(c).

 

Notwithstanding
anything herein to the contrary, on the Termination Date, this Warrant shall be automatically exercised via cashless exercise pursuant
to this Section 1(c).

 

(d) Mechanics
of Exercise.

 

i. Delivery
of Warrant Shares Upon Exercise. Warrant Shares purchased hereunder shall be transmitted by the Transfer Agent to the Holder by
crediting the account of the Holder’s 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) 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 five (5) Trading Days after the delivery to the Company of the
Notice of Exercise (such date, the “Warrant Share Delivery Date”). The Warrant Shares shall be deemed to have
been issued, and Holder or any other person so designated to be named therein shall be deemed to have become a holder of record of
such shares for all purposes, as of the date the Warrant has been exercised, with payment to the Company of the Exercise Price (or
by cashless exercise, if permitted) and all taxes required to be paid by the Holder, if any, pursuant to Section 1(d)(vi) prior to
the issuance of such shares, having been paid.

 

    	2

     

    

 

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

 

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

 

    	3

     

    

 

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

 

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

 

(e) Holder’s
Exercise Limitations. The Company shall not effect any exercise of this Warrant, and a Holder shall not have the right to
exercise any portion of this Warrant, pursuant to Section 2 or otherwise, to the extent that after giving effect to such issuance
after exercise as set forth on the applicable Notice of Exercise, the Holder (together with the Holder’s Affiliates, and any
other Persons acting as a group together with the Holder or any of the Holder’s Affiliates), would beneficially own in excess
of the Beneficial Ownership Limitation (as defined below). For purposes of the foregoing sentence, the number of shares of Common
Stock beneficially owned by the Holder and its Affiliates shall include the number of shares of Common Stock issuable upon exercise
of this Warrant with respect to which such determination is being made, but shall exclude the number of shares of Common Stock which
would be issuable upon (i) exercise of the remaining, nonexercised portion of this Warrant beneficially owned by the Holder or any
of its Affiliates and (ii) exercise or conversion of the unexercised or nonconverted portion of any other securities of the Company
(including, without limitation, any other Common Stock Equivalents) subject to a limitation on conversion or exercise analogous to
the limitation contained herein beneficially owned by the Holder or any of its Affiliates. Except as set forth in the preceding
sentence, for purposes of this Section 1(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 1(e) applies, the determination of whether this Warrant is exercisable (in relation to other securities owned by the Holder
together with any Affiliates) and of which portion of this Warrant is exercisable shall be in the sole discretion of the Holder, and
the submission of a Notice of Exercise shall be deemed to be the Holder’s determination of whether this Warrant is exercisable
(in relation to other securities owned by the Holder together with any Affiliates) and of which portion of this Warrant is
exercisable, in each case subject to the Beneficial Ownership Limitation, and the Company shall have no obligation to verify or
confirm the accuracy of such determination. In addition, a determination as to any group status as contemplated above shall be
determined in accordance with Section 13(d) of the Exchange Act and the rules and regulations promulgated thereunder. For purposes
of this Section 1(e), in determining the number of outstanding shares of Common Stock, a Holder may rely on the number of
outstanding shares of Common Stock as reflected in (A) the Company’s most recent periodic or annual report filed with the
Commission, as the case may be, (B) a more recent public announcement by the Company or (C) a more recent written notice by the
Company or the Transfer Agent setting forth the number of shares of Common Stock outstanding. Upon the written or oral request of a
Holder, the Company shall within two Trading Days confirm orally and in writing to the Holder the number of shares of Common Stock
then outstanding. In any case, the number of outstanding shares of Common Stock shall be determined after giving effect to the
conversion or exercise of securities of the Company, including this Warrant, by the Holder or its Affiliates since the date as of
which such number of outstanding shares of Common Stock was reported. The “Beneficial Ownership Limitation” shall
be 4.99% of the number of shares of the Common Stock outstanding immediately after giving effect to the issuance of shares of Common
Stock issuable upon exercise of this Warrant. The Holder, upon notice to the Company, may increase or decrease the Beneficial
Ownership Limitation provisions of this Section 2(e), provided that the Beneficial Ownership Limitation in no event exceeds 9.99% of
the number of shares of the Common Stock outstanding immediately after giving effect to the issuance of shares of Common Stock upon
exercise of this Warrant held by the Holder and the provisions of this Section 1(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 1(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

2. Certain
Adjustments.

 

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

 

(b) Subsequent
Equity Sales. If, at any time while this Warrant is outstanding and prior to the time the Common Stock is listed on a national
stock exchange, including in any public offering of Common Stock associated with the original listing of the Common Stock on a
national securities exchange, the Company sells or grants any option to purchase or sells or grants any right to reprice, or
otherwise disposes of or issues (or announces any sale, grant or any option to purchase or other disposition), any Common Stock or
Common Stock Equivalents entitling any Person to acquire shares of Common Stock at an effective price per share that is lower than
the then Exercise Price (such lower price, the “Base Exercise Price” and such issuances, collectively, a
“Dilutive Issuance”) (if the holder of the Common Stock or Common Stock Equivalents so issued shall at any time,
whether by operation of purchase price adjustments, reset provisions, floating conversion, exercise or exchange prices or otherwise,
or due to warrants, options or rights per share which are issued in connection with such issuance, be entitled to receive shares of
Common Stock at an effective price per share that is lower than the then Exercise Price, such issuance shall be deemed to have
occurred for less than the Exercise Price on such date of the Dilutive Issuance), then the Exercise Price shall be reduced to equal
the Base Exercise Price. Such adjustment shall be made whenever such Common Stock or Common Stock Equivalents are issued.
Notwithstanding the foregoing, no adjustment will be made under this Section 2(b) in respect of an Exempt Issuance. The Company
shall notify the Holder in writing, no later than the Trading Day following the issuance of any Common Stock or Common Stock
Equivalents subject to this Section 2(b), indicating therein the applicable issuance price, or applicable reset price, exchange
price, exercise price, conversion price and other pricing terms (such notice, the “Dilutive Issuance Notice”).
For purposes of clarification, whether or not the Company provides a Dilutive Issuance Notice pursuant to this Section 2(b), upon
the occurrence of any Dilutive Issuance, the Holder is entitled to receive a number of Warrant Shares based upon the Base Exercise
Price on or after the date of such Dilutive Issuance, regardless of whether the Holder accurately refers to the Base Exercise Price
in the Notice of Exercise.

 

    	5

     

    

 

(c) Subsequent
Rights Offerings. In addition to any adjustments pursuant to Section 2(a) and 2(b) above, if at any time the Company grants,
issues or sells any Common Stock Equivalents or rights to purchase stock, warrants, securities or other property pro rata to the
record holders of any class of shares of Common Stock (the “Purchase Rights”), then the Holder will be entitled
to acquire, upon the terms applicable to such Purchase Rights, the aggregate Purchase Rights which the Holder could have acquired if
the Holder had held the number of shares of Common Stock acquirable upon complete exercise of this Warrant (without regard to any
limitations on exercise hereof, including without limitation, the Beneficial Ownership Limitation) immediately before the date on
which a record is taken for the grant, issuance or sale of such Purchase Rights, or, if no such record is taken, the date as of
which the record holders of shares of Common Stock are to be determined for the grant, issue or sale of such Purchase Rights
(provided, however, to the extent that the Holder’s right to participate in any such Purchase Right would result in the Holder
exceeding the Beneficial Ownership Limitation, then the Holder shall not be entitled to participate in such Purchase Right to such
extent (or beneficial ownership of such shares of Common Stock as a result of such Purchase Right to such extent) and such Purchase
Right to such extent shall be held in abeyance for the Holder until such time, if ever, as its right thereto would not result in the
Holder exceeding the Beneficial Ownership Limitation).

 

(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 shares of Common Stock, by way of return of capital or
otherwise (including, without limitation, any distribution of cash, stock 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, upon the exercise of
this Warrant, 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 shares of Common Stock acquirable upon complete exercise of this Warrant
(without regard to any limitations on exercise hereof, including without limitation, the Beneficial Ownership Limitation)
immediately before the date 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 shares of Common Stock 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 in the
beneficial ownership of any shares of Common Stock 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).

 

    	6

     

    

 

(e) Fundamental
Transaction. If, at any time while this Warrant is outstanding, (i) the Company, directly or indirectly, in one or more related
transactions effects any merger or consolidation of the Company with or into another Person, (ii) the Company, directly or
indirectly, effects any sale, lease, license, assignment, transfer, conveyance or other disposition of all or substantially all of
its assets in one or a series of related transactions, (iii) any, direct or indirect, purchase offer, tender offer or exchange offer
(whether by the Company or another Person) is completed pursuant to which holders of Common Stock are permitted to sell, tender or
exchange their shares for other securities, cash or property and has been accepted by the holders of 50% or more of the outstanding
Common Stock, (iv) the Company, directly or indirectly, in one or more related transactions effects any reclassification,
reorganization or recapitalization of the Common Stock or any compulsory share exchange pursuant to which the Common Stock is
effectively converted into or exchanged for other securities, cash or property, or (v) the Company, directly or indirectly, in one
or more related transactions consummates a stock or share purchase agreement or other business combination (including, without
limitation, a reorganization, recapitalization, spin-off or scheme of arrangement) with another Person or group of Persons whereby
such other Person or group acquires more than 50% of the outstanding shares of Common Stock (not including any shares of Common
Stock held by the other Person or other Persons making or party to, or associated or affiliated with the other Persons making or
party to, such stock or share purchase agreement or other business combination) (each a “Fundamental
Transaction”), then, upon any subsequent exercise of this Warrant, the Holder shall have the right to receive, for each
Warrant Share that would have been issuable upon such exercise immediately prior to the occurrence of such Fundamental Transaction,
at the option of the Holder (without regard to any limitation in Section 1(e) on the exercise of this Warrant), the number of shares
of Common Stock of the successor or acquiring corporation or of the Company, if it is the surviving corporation, and any additional
consideration (the “Alternate Consideration”) receivable as a result of such Fundamental Transaction by a holder
of the number of shares of Common Stock for which this Warrant is exercisable immediately prior to such Fundamental Transaction
(without regard to any limitation in Section 1(e) on the exercise of this Warrant). For purposes of any such exercise, the
determination of the Exercise Price shall be appropriately adjusted to apply to such Alternate Consideration based on the amount of
Alternate Consideration issuable in respect of one share of Common Stock in such Fundamental Transaction, and the Company shall
apportion the Exercise Price among the Alternate Consideration in a reasonable manner reflecting the relative value of any different
components of the Alternate Consideration. If holders of Common Stock are given any choice as to the securities, cash or property to
be received in a Fundamental Transaction, then the Holder shall be given the same choice as to the Alternate Consideration it
receives upon any exercise of this Warrant following such Fundamental Transaction. The Company shall cause any successor entity in a
Fundamental Transaction in which the Company is not the survivor (the “Successor Entity”) to assume in writing
all of the obligations of the Company under this Warrant and the other Transaction Documents in accordance with the provisions of
this Section 2(e) pursuant to written agreements in form and substance reasonably satisfactory to the Holder and approved by the
Holder (without unreasonable delay) prior to such Fundamental Transaction and shall, at the option of the Holder, deliver to the
Holder in exchange for this Warrant a security of the Successor Entity evidenced by a written instrument substantially similar in
form and substance to this Warrant which is exercisable for a corresponding number of shares of capital stock of such Successor
Entity (or its parent entity) equivalent to the shares of Common Stock acquirable and receivable upon exercise of this Warrant
(without regard to any limitations on the exercise of this Warrant) prior to such Fundamental Transaction, and with an exercise
price which applies the exercise price hereunder to such shares of capital stock (but taking into account the relative value of the
shares of Common Stock pursuant to such Fundamental Transaction and the value of such shares of capital stock, such number of shares
of capital stock and such exercise price being for the purpose of protecting the economic value of this Warrant immediately prior to
the consummation of such Fundamental Transaction), and which is reasonably satisfactory in form and substance to the Holder. Upon
the occurrence of any such Fundamental Transaction, the Successor Entity shall succeed to, and be substituted for (so that from and
after the date of such Fundamental Transaction, the provisions of this Warrant and the other Transaction Documents referring to the
“Company” shall refer instead to the Successor Entity), and may exercise every right and power of the Company and shall
assume all of the obligations of the Company under this Warrant and the other Transaction Documents with the same effect as if such
Successor Entity had been named as the Company herein.

 

(f) Calculations.
All calculations under this Section 2 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 2, the number of shares of Common Stock deemed to be issued and outstanding as of a given date shall be the
sum of the number of shares of Common Stock (excluding treasury shares, if any) issued and outstanding.

(g) Notice
to Holder.

 

i. Adjustment
to Exercise Price. Whenever the Exercise Price is adjusted pursuant to any provision of this Section 2, the Company shall
promptly mail to the Holder a notice setting forth the Exercise Price after such adjustment and any resulting adjustment to the
number of Warrant Shares and setting forth a brief statement of the facts requiring such adjustment.

 

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

 

3. Transfer
of Warrant.

 

(a) Transferability.
Subject to compliance with any applicable securities laws and the conditions set forth in Section 3(d) hereof, this Warrant and all
rights hereunder 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

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 3(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.

 

(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, make usual and customary representations as to investment intent to the Company.

 

(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.

 

4. Miscellaneous.

 

(a)
No Rights as Stockholder Until Exercise. This Warrant does not entitle the Holder to any voting rights, dividends or other rights
as a stockholder of the Company prior to the exercise hereof as set forth in Section 1(d)(i), except as expressly set forth in Section
2.

 

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

 

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

 

    	9

     

    

 

(d)
Authorized Shares.

 

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

 

ii. 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.

 

iii. 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 laws of the State of Nevada as they are applied to contracts executed, delivered and to be wholly performed within
the State of Nevada.

 

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

 

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