Exhibit 4.2


 


PRE-FUNDED COMMON SHARE PURCHASE WARRANT


 


NLS PHARMACEUTICS
LTD.


 





	Warrant Shares: ______	 	Initial Exercise Date: [___], 2022



 


THIS PRE-FUNDED COMMON SHARE PURCHASE
WARRANT, issued in the form of uncertificated securities (Wertrechte) pursuant to article 973c of the Swiss Code of Obligations
(the “Warrant”), certifies that, for value received, _____________ or its assigns (the “Holder”)
is entitled, upon the terms and subject to the limitations on exercise and the conditions hereinafter set forth, at any time on or after
the date hereof (the “Initial Exercise Date”) until this Warrant is exercised in full (the “Termination Date”)
but not thereafter, to subscribe for and purchase from NLS Pharmaceutics Ltd., a corporation incorporated under the laws of Switzerland
(the “Company”), up to [____] shares (as subject to adjustment hereunder, the “Warrant Shares”)
of Common Shares. The purchase price of one Common Share under this Warrant shall be equal to the Exercise Price, as defined in Section
2(b).


 


Section 1. Definitions.
Capitalized terms used and not otherwise defined herein shall have the meanings set forth in that certain Securities Purchase Agreement
(the “Purchase Agreement”), dated April 13, 2022, among the Company and the purchasers signatory thereto:


 


“Business Day”
means any day except any Saturday, any Sunday, any day which is a federal legal holiday in the United States or Switzerland or any day
on which banking institutions in the State of New York or in the Canton of Zurich (Switzerland) are authorized or required by law or other
governmental action to close.


 


Section 2. Exercise.


 


a) Exercise
of Warrant. Exercise of the purchase rights represented by this Warrant may be made, in whole or in part, at any time or times on
or after the Initial Exercise Date and on or before the Termination Date by delivery to the Company 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 to the Company’s Swiss bank account in Switzerland.
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) 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 aggregate exercise price of this Warrant, except for a nominal exercise price of CHF 0.02 per Warrant Share, was pre-funded
to the Company on or prior to the Initial Exercise Date and, consequently, no additional consideration (other than the nominal exercise
price of CHF 0.02 per Warrant Share) shall be required to be paid by the Holder to any Person to effect any exercise of this Warrant.
The Holder shall not be entitled to the return or refund of all, or any portion, of such pre-paid aggregate exercise price under any circumstance
or for any reason whatsoever. The remaining unpaid exercise price per Common Share under this Warrant shall be CHF 0.02, subject to adjustment
hereunder (the “Exercise Price”). In no event shall the Exercise Price be adjusted below the nominal value (or U.S.
dollar equivalent) of the Common Shares, which is CHF 0.02 as of the Initial Exercise Date.


 


		c)	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 there is an effective registration statement permitting the issuance of the Warrant Shares to or resale of the Warrant Shares by the
Holder, 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 latest of (i) five (5) Business Days after the delivery to the Company of
the Notice of Exercise; and (ii) two (2) Business Days after delivery of the aggregate Exercise Price to the Company and (iii) 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 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 Shares on the date of the applicable Notice of Exercise), $10 per Trading
Day (increasing to $20 per Trading Day on the fifth Trading Day after the Warrant Share Delivery Date) for each Trading Day after such
Warrant Share Delivery Date until such Warrant Shares are delivered or Holder rescinds such exercise. The liquidated damages amount set
forth in this Section 2(d)(i) shall not be duplicative of an identical liquidated damages amount set forth in Section 4.1(d) of the Purchase
Agreement. 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 execution of the Purchase Agreement,
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, provided that payment of the aggregate
Exercise Price is received prior to or by such Warrant Share Delivery Date. The Company shall deliver in due course the Company’s
book of uncertificated securities (Wertrechtebuch) duly signed by the Company’s share registrar and evidencing the Holder
as holder of the Warrant Shares, if the Shares of the Company are not already listed.


 






    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 certificate, at the time of delivery of the Warrant Shares, deliver to the Holder a new Warrant evidencing
the rights of the Holder to purchase the unpurchased Warrant Shares called for by this Warrant, which new Warrant shall in all other respects
be identical with this Warrant.


 


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


 


iv. Compensation
for Buy-In on Failure to Timely Deliver Warrant Shares Upon Exercise. In addition to any other rights available to the Holder, if
the Company fails to cause the Transfer Agent to transmit to the Holder the Warrant Shares in accordance with the provisions of Section
2(d)(i) above pursuant to an exercise on or before the Warrant Share Delivery Date, and if after such date the Holder is required by its
broker to purchase (in an open market transaction or otherwise) or the Holder’s brokerage firm otherwise purchases, Common Shares
to deliver in satisfaction of a sale by the Holder of the Warrant Shares which the Holder anticipated receiving upon such exercise (a
“Buy-In”), then the Company shall (A) pay in cash to the Holder the amount, if any, by which (x) the Holder’s
total purchase price (including brokerage commissions, if any) for the Common Shares so purchased exceeds (y) the amount obtained by multiplying
(1) the number of Warrant Shares that the Company was required to deliver to the Holder in connection with the exercise at issue times
(2) the price at which the sell order giving rise to such purchase obligation was executed, and (B) at the option of the Holder, either
reinstate the portion of the Warrant and equivalent number of Warrant Shares for which such exercise was not honored (in which case such
exercise shall be deemed rescinded) or deliver to the Holder the number of Common Shares that would have been issued had the Company timely
complied with its exercise and delivery obligations hereunder. For example, if the Holder purchases Common Shares having a total purchase
price of $11,000 to cover a Buy-In with respect to an attempted exercise of Common Shares with an aggregate sale price giving rise to
such purchase obligation of $10,000, under clause (A) of the immediately preceding sentence the Company shall be required to pay the Holder
$1,000. The Holder shall provide the Company written notice indicating the amounts payable to the Holder in respect of the Buy-In and,
upon request of the Company, evidence of the amount of such loss. Nothing herein shall limit a Holder’s right to pursue any other
remedies available to it hereunder, at law or in equity including, without limitation, a decree of specific performance and/or injunctive
relief with respect to the Company’s failure to timely deliver Common Shares upon exercise of the Warrant as required pursuant to
the terms hereof. The liquidated damages amount set forth in this Section 2(d)(i) shall not be duplicative of an identical liquidated
damages amount set forth in Section 4.1(d) of the Purchase Agreement.


 


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 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 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 (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. 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%/9.99%] of the number of shares of the 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 shares of the Common Shares outstanding immediately after
giving effect to the issuance of Common Shares upon exercise of this Warrant held by the Holder and the provisions of this Section 2(e)
shall continue to apply. Any 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) 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 its Common Shares or any other equity or equity equivalent securities payable in Common Shares (which,
for avoidance of doubt, shall not include any Common Shares issued by the Company upon exercise of this Warrant), (ii) subdivides outstanding
Common Shares into a larger number of shares, (iii) combines (including by way of reverse stock split) outstanding Common Shares into
a smaller number of shares, or (iv) issues by reclassification of shares of the Common Shares 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 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 stockholders entitled to receive such dividend or distribution and shall become
effective immediately after the effective date in the case of a subdivision, combination or re-classification.


 


b) Subsequent
Rights Offerings. In addition to any adjustments pursuant to Section 3(a) above, if at any time the Company grants, issues or sells
any Common Share Equivalents or rights to purchase stock, 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).


 


c) Pro
Rata Distributions. During such time as this Warrant is outstanding, if the Company shall declare or make any dividend or other distribution
of its assets (or rights to acquire its assets) to holders of Common Shares, by way of return of capital or otherwise (including, without
limitation, any distribution of cash, 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, 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).


 






    5 


     


    

 


d) 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 or group of Persons whereby such other Person or group
acquires more than 50% of the outstanding Common Shares or 50% or more of the voting power of the common equity of the Company, (ii) the
Company, directly or indirectly, effects any sale, lease, license, assignment, transfer, conveyance or other disposition of all or substantially
all of its assets in one or a series of related transactions, (iii) any, direct or indirect, purchase offer, tender offer or exchange
offer (whether by the Company or another Person) is completed pursuant to which holders of Common Shares are permitted to sell, tender
or exchange their shares for other securities, cash or property and has been accepted by the holders of 50% or more of the outstanding
Common Shares, (iv) the Company, directly or indirectly, in one or more related transactions effects any reclassification, reorganization
or recapitalization of the Common Shares or any compulsory share exchange pursuant to which the Common Shares 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, 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) 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.
The Company shall cause any successor entity in a Fundamental Transaction in which the Company is not the survivor (the “Successor
Entity”) to assume in writing all of the obligations of the Company under this Warrant and the other Transaction Documents in
accordance with the provisions of this Section 3(e) pursuant to written agreements in form and substance reasonably satisfactory to the
Holder and approved by the Holder (without unreasonable delay) prior to such Fundamental Transaction and shall, at the option of the Holder,
deliver to the Holder in exchange for this Warrant a security of the Successor Entity evidenced by a written instrument substantially
similar in form and substance to this Warrant which is exercisable for a corresponding number of shares of capital stock of such Successor
Entity (or its parent entity) equivalent to the 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 shares of capital stock (but taking into account the relative value of the Common Shares 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 be added to the term “Company” under this Warrant (so that from and after the occurrence or consummation
of such Fundamental Transaction, each and every provision of this Warrant and the other Transaction Documents referring to the “Company”
shall refer instead to each of the Company and the Successor Entity or Successor Entities, jointly and severally), and the Successor Entity
or Successor Entities, jointly and severally with the Company, may exercise every right and power of the Company prior thereto and the
Successor Entity or Successor Entities shall assume all of the obligations of the Company prior thereto under this Warrant and the other
Transaction Documents with the same effect as if the Company and such Successor Entity or Successor Entities, jointly and severally, had
been named as the Company herein.


 






    6 


     


    

 


e) 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.


 


f) 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 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 Shares, any consolidation or merger to which the Company (or any of its Subsidiaries) is a party, any sale or transfer of
all or substantially all of its assets, or any compulsory share exchange whereby the Common Shares 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 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 5 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 shares of the 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 and provided, further that no notice shall be required if the information is
disseminated in a press release or document filed with the Securities and Exchange Commission. 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 Report on 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.


 


iii. Voluntary
Adjustments by the Company. The Company may, at any time during the term of this Warrant, reduce the then current Exercise Price to
any amount for any period of time deemed appropriate by the Board of Directors of the Company, with the consent of the Holder.

Section 4. Transfer
of Warrant.


 


a) Transferability.
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. This Warrant, if properly assigned in accordance herewith, may be exercised by a new holder for
the purchase of Warrant Shares without having a new Warrant issued.


 


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


 


Section 5. Miscellaneous.


 


a) No
Rights as Stockholder Until Exercise; No Settlement in Cash. 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 2(d)(i), except as expressly set
forth in Section 3. Without limiting any rights of a Holder 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.


 






    8 


     


    

 


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


 


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


 


d) Authorized
Shares.


 


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


 


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


 






    9 


     


    

 


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


 


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


 


f) Restrictions.
The Holder acknowledges that the Warrant Shares acquired upon the exercise of this Warrant, if not registered, and the Holder will not
be permitted to 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. Without limiting any other provision of this
Warrant or the Purchase Agreement, 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 notice, request or other document required or permitted to be given or delivered to the Holder by the Company shall be delivered in
accordance with the notice provisions of the Purchase Agreement.


 


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


 


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


 






    10 


     


    

 


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, on the one hand, and
the Holder, on the other hand.


 


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.
