Section 2.          Exercise.

 

a)          Exercise
of the purchase rights represented by this Warrant may be made, in whole or in part, at any time or times on or after the Initial
Exercise Date and on or before the Termination Date by delivery to the Company (or such other office or agency of the Company as
it may designate by notice in writing to the registered Holder at the address of the Holder appearing on the books of the Company)
of a duly executed facsimile copy or PDF copy submitted by electronic (or e-mail attachment) of the Notice of Exercise in the form
annexed hereto (“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 shares specified in the applicable Notice of Exercise
by wire transfer or cashier’s check drawn on a United States bank unless the cashless exercise procedure specified in Section
2(c) below is specified in the applicable Notice of Exercise. No ink-original Notice of Exercise shall be required, nor shall any
medallion guarantee (or other type of guarantee or notarization) of any Notice of Exercise form be required. Notwithstanding anything
herein to the contrary, the Holder shall not be required to physically surrender this Warrant to the Company until the Holder has
purchased all of the Warrant Shares available hereunder and the Warrant has been exercised in full, in which case, the Holder shall
surrender this Warrant to the Company for cancellation within three (3) Trading Days of the date 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

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.

 

    	 	2	 

     

    

 

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

 

c)       Cashless
Exercise. If at the time of exercise hereof there is no effective registration statement registering, or the prospectus contained
therein is not available for the issuance of the Warrant Shares to the Holder, then, upon exercise of this Warrant by the Holder,
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 date of the Notice of Exercise giving rise
to the applicable “cashless exercise”, as set forth in the applicable Notice of Exercise (if the Notice of Exercise
is delivered after 4:02 p.m. on a Trading Day, the VWAP will be the VWAP as calculated at the end of such Trading Day, and in
the event that a Notice of Exercise is delivered prior to 4:02 p.m. on a Trading Day, the prior Trading Day’s VWAP shall
be used in this calculation);

 

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

 

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

 

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

 

“VWAP”
means, for any date, the price determined by the first of the following clauses that applies: (a) if the Common Stock is then listed
or quoted on a Trading Market, the daily volume weighted average price of the Common Stock for such date (or the nearest preceding
date) on the Trading Market on which the Common Stock is then listed or quoted as reported by Bloomberg L.P. (based on a Trading
Day from 9:30 a.m. (New York City time) to 4:02 p.m. (New York City time)), (b)  if OTCQB or OTCQX is not a Trading Market,
the volume weighted average price of the Common Stock for such date (or the nearest preceding date) on OTCQB or OTCQX as applicable,
(c) if the Common Stock is not then listed or quoted for trading on OTCQB or OTCQX and if prices for the Common Stock are then
reported in the “Pink Sheets” published by OTC Markets Group, Inc. (or a similar organization or agency succeeding
to its functions of reporting prices), the most recent bid price per share of the Common Stock so reported, or (d) in all
other cases, the fair market value of a share of Common Stock as determined by an independent appraiser selected in good faith
by the holders of a majority in interest of the Warrants then outstanding and reasonably acceptable to the Company, the fees and
expenses of which shall be paid by the Company.

 

Notwithstanding
anything herein to the contrary, on the Termination Date, this Warrant shall be automatically exercised via cashless exercise pursuant
to this Section 2(c).

 

    	 	3	 

     

    

 

d)       Mechanics
of Exercise.

 

i.            Delivery
of Warrant Shares Upon Exercise. The Company shall cause the Warrant Shares purchased hereunder to be transmitted by the Transfer
Agent to the Holder by crediting the account of the Holder’s or its designee’s balance account with The Depository
Trust Company through its Deposit or Withdrawal at Custodian system (“DWAC”) if the Company is then a participant
in such system and either (A) there is an effective registration statement permitting the issuance of the Warrant Shares to or
resale of the Warrant Shares by Holder or (B) 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 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 and (ii) the number of Trading
Days comprising the Standard Settlement Period (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 after the delivery to the
Company of the Notice of Exercise. If the Company fails for any reason to deliver to the Holder the Warrant Shares subject to a
Notice of Exercise by the Warrant Share Delivery Date, the Company shall pay to the Holder, in cash, as liquidated damages and
not as a penalty, for each $1,000 of Warrant Shares subject to such exercise (based on the VWAP of the Common Stock on the date
of the applicable Notice of Exercise), $10 per Trading Day (increasing to $20 per Trading Day on the fifth Trading Day after such
liquidated damages begin to accrue) for each Trading Day after such Warrant Share Delivery Date until such Warrant Shares are delivered
or Holder rescinds such exercise. 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 Stock as
in effect on the date of delivery of the Notice of Exercise.

 

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

 

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

 

    	 	4	 

     

    

 

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

 

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

 

vi.         Charges,
Taxes and Expenses. Issuance of Warrant Shares shall be made without charge to the Holder for any issue or transfer tax or
other incidental expense in respect of the issuance of 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.

 

    	 	5	 

     

    

 

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

 

b)         [Reserved]

 

c)         Subsequent
Rights Offerings. In addition to any adjustments pursuant to Section 3(a) above, if at any time the Company grants, issues
or sells any Common Stock Equivalents or rights to purchase stock, warrants, securities or other property pro rata to the record
holders of any class of shares of Common Stock (the “Purchase Rights”), then, upon any exercise of this Warrant,
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).

 

    	 	7	 

     

    

 

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 all 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) other than
a dividend or other distribution of the type described in Section 3(a) above (a “Distribution”), at any time
after the issuance of this Warrant, then, upon any 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, 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 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).

 

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

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

 

g)       Notice
to Holder.

 

i.            Adjustment
to Exercise Price. Whenever the Exercise Price is adjusted pursuant to any provision of this Section 3, the Company shall promptly
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 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 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 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 deliver such notice
or any defect therein or in the delivery thereof shall not affect the validity of the corporate action required to be specified
in such notice. To the extent that any notice provided in this Warrant constitutes, or contains, material, non-public information
regarding the Company or any of the Subsidiaries, the Company shall simultaneously file such notice with the Commission pursuant
to a Current Report on Form 8-K. The Holder shall remain entitled to exercise this Warrant during the period commencing on the
date of such notice to the effective date of the event triggering such notice except as may otherwise be expressly set forth herein.

Section 4.          Transfer
of Warrant.

 

a)          Transferability.
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.

 

    	 	10	 

     

    

 

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

 

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

 

Section 5.          Miscellaneous.

 

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

 

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

 

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

 

d)       Authorized
Shares.

 

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

 

    	 	11	 

     

    

 

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

 

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

 

e)       Jurisdiction.
This Warrant shall be governed by and construed and enforced in accordance with the laws of the State of New York, without giving
effect to conflict of laws principles thereof. The Company hereby agrees that any action, proceeding or claim against it arising
out of, or relating in any way to this Warrant shall be brought and enforced in the New York Supreme Court, County of New York,
or in the United States District Court for the Southern District of New York located in the Borough of Manhattan in the City of
New York, and irrevocably submits to such jurisdiction, which jurisdiction shall be exclusive. The Company hereby waives any objection
to such exclusive jurisdiction and that such courts represent an inconvenient forum.

 

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

 

g)       Nonwaiver
and Expenses. No course of dealing or any delay or failure to exercise any right hereunder on the part of Holder shall operate
as a waiver of such right or otherwise prejudice the Holder’s rights, powers or remedies. 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.

 

    	 	12

Any notices, consents, waivers or other document or communications required or permitted to be given or delivered under the terms
of this Warrant must be in writing and will be deemed to have been delivered: (i) upon receipt, if delivered personally; (ii) when
sent, if sent by facsimile (provided confirmation of transmission is mechanically or electronically generated and kept on file
by the sending party); (iii) when sent, if sent by e-mail (provided that such sent e-mail is kept on file (whether electronically

e-mail server that such e-mail could not be delivered to such recipient) and (iv) if sent by overnight courier service, one (1)

i)         Limitation

Warrant Shares, and no enumeration herein of the rights or privileges of the Holder, shall give rise to any liability of the Holder
for the purchase price of any Common Stock or as a stockholder of the Company, whether such liability is asserted by the Company
or by creditors of the Company.

 

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

 

    	 	13	 

     

    

 

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 by the
holders of a majority in interest of the Warrants then outstanding (as measured by the number of shares of Common Stock underlying
such 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.

OPTION BY ITS ACCEPTANCE HEREOF, AGREES THAT THE SECURITIES EVIDENCED BY THIS UNIT PURCHASE OPTION MAY NOT BE SOLD, TRANSFERED
OR ASSIGNED EXCEPT AS HEREIN PROVIDED AND THE REGISTERED HOLDER OF THIS UNIT PURCHASE OPTION AGREES THAT THE SECURITIES EVIDENCED
BY THIS UNIT PURCHASE OPTION WILL NOT BE SOLD, TRANSFERED, 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 THIS UNIT PURCHASE
OPTION OR THE SECURITIES EVIDENCED BY THIS UNIT PURCHASE OPTION, FOR A PERIOD OF ONE HUNDRED EIGHTY (180) DAYS FOLLOWING THE EFFECTIVE

ALL SECURITIES SO TRANSFERRED REMAIN SUBJECT TO THE LOCK-UP RESTRICTION SET FORTH ABOVE FOR THE REMAINDER OF THE TIME PERIOD.

 

UNIT PURCHASE OPTION

FOR THE PURCHASE OF [●] UNITS

OF NANOVIBRONIX, INC.

 

1.             Unit
Purchase Option.

 

THIS CERTIFIES THAT, in
consideration of $100.00 duly paid by or on behalf of Dawson James Securities, Inc. (“Dawson” or “Holder”),
as registered owner of this Unit Purchase Option, to NanoVibronix, Inc. (the “Company”), Holder is entitled,
at any time or from time to time commencing on the 180th day after the effective date (the “Effective Date”)
of the registration statement (the “Registration Statement”) pursuant to which certain units of securities are
offered for sale to the public (the “Offering”) (the “Commencement Date”), and at or before
5:00 p.m., Eastern Time, on the fifth anniversary of the Effective Date (the “Expiration Date”), but not
thereafter, to subscribe for, purchase and receive, in whole or in part, up to [●] units (the “Units”)
of the Company, each Unit consisting of one share of the Company’s common stock, par value $0.001 per share (the “Shares”)
and warrants to purchase [●] Shares (the “Warrant(s)”). Each Warrant is the same as the warrants included
in the Units being registered for sale to the public (the “Public Warrants”) under the Securities Act of 1933,
as amended (the “Act”). If the Expiration Date is a day on which banking institutions are authorized by law
to close, then this Unit Purchase Option may be exercised on the next succeeding day which is not such a day in accordance with
the terms herein. During the period ending on the Expiration Date, the Company agrees not to take any action that would terminate
the Unit Purchase Option. This Unit Purchase Option is initially exercisable at $[●] per Unit (or 125% of the public offering
price of the unit of securities being sold in the Offering) so purchased; provided, however, that upon the occurrence of any of
the events specified in Section 5 hereof, the rights granted by this Unit Purchase Option, including the exercise price per
Unit and the number of Units to be received upon such exercise, shall be adjusted as therein specified. The term “Exercise
Price” shall mean the initial exercise price or the adjusted exercise price, depending on the context.

 

     

     

    

 

2.             Exercise.

 

(a)       Exercise
Procedure. In order to exercise this Unit Purchase Option, the exercise
form attached hereto must be duly executed and completed and delivered to the Company, together with this Unit Purchase Option
and payment of the Exercise Price for the Units being purchased payable in cash or by certified check or official bank check.
If the subscription rights represented hereby shall not be exercised at or before 5:00 p.m., Eastern time, on the Expiration
Date, this Unit Purchase Option shall become and be void without further force or effect, and all rights represented hereby shall
cease and expire.

 

(b)       Legend.
If required by applicable law at the time of any exercise, each certificate
for the securities purchased under this Unit Purchase Option shall bear a legend as follows unless such securities have been registered
under the Act:

 

“The securities represented
by this certificate have not been registered under the Securities Act of 1933, as amended (the “Act”) or applicable
state law. The securities may not be offered for sale, sold or otherwise transferred except pursuant to an effective registration
statement under the Act, or pursuant to an exemption from registration under the Act and applicable state law.”

 

(c)       Cashless
Exercise.

 

(i)       In
lieu of the payment of the Exercise Price multiplied by the number of Units for which this Unit Purchase Option is exercisable
(and in lieu of being entitled to receive Shares and Warrants) in the manner required by Section 2(a), the Holder shall have
the right (but not the obligation) to convert any exercisable but unexercised portion of this Unit Purchase Option into Units consisting
of Shares and Warrants (the “Conversion Right”) as follows:

 

(A)       Upon
exercise of the Conversion Right, the Company shall deliver to the Holder (without payment by the Holder of any of the Exercise
Price in cash) that number of Shares equal to the quotient obtained by dividing (x) the Value of the portion of the Unit Purchase
Option being converted by (y) the Current Market Price of a Share.

 

(B)       The
“Value” of the portion of the Unit Purchase Option being converted shall equal the remainder derived by subtracting
(a) (i) the Exercise Price multiplied by (ii) the number of Units underlying the portion of this Unit Purchase Option
being converted, from (b) the Current Market Value of a Unit multiplied by the number of Units underlying the portion of the
Unit Purchase Option being converted.

 

(C)       As
used herein, the term “Current Market Value” per Unit at any date means the remainder derived by subtracting
(x) the exercise price of the Warrants multiplied by the number of Shares issuable upon exercise of the Warrants underlying
one Unit from (y) the Current Market Price of the Shares multiplied by the number of Shares included within one Unit and underlying
the Warrants included within one Unit.

 

    	 	2	 

     

    

 

(D)       The
“Current Market Price” of a Share shall mean (i) if the Shares are listed on a national securities exchange
or quoted on the OTCQB or OTCQX (or any successor exchange or entity), the closing or last sale price of the Shares in the principal
trading market for the Shares on the last trading day preceding the day in question as reported by the exchange, the OTCQB or OTCQX,
as the case may be; (ii) if the Shares are not listed on a national securities exchange or quoted on the OTCQB or OTCQX, but
are traded in the residual over-the-counter market, the closing bid price for the Shares on the last trading day preceding the
date in question for which such quotations are reported in the “Pink Sheets” published by OTC Markets Group, Inc. or
similar publisher of such quotations; and (iii) if the fair market value of the Shares cannot be determined pursuant to clause (i)
or (ii) above, such price as the Board of Directors of the Company shall determine, in good faith.

 

(ii)       The
Cashless Exercise Right may be exercised by the Holder on any business day on or after the Commencement Date and not later than
the Expiration Date by delivering the Unit Purchase Option with the duly executed exercise form attached hereto with the cashless
exercise section completed to the Company, exercising the Cashless Exercise Right and specifying the total number of Units the
Holder will purchase pursuant to such Cashless Exercise Right.

 

(d)       Resale
of Shares. Holder and the Company acknowledge that as of the date hereof the Staff of the Division
of Corporation Finance of the SEC has published Compliance & Disclosure Interpretation 528.04 in the Securities Act Rules section
thereof, stating that the holder of securities issued in connection with a public offering may not rely upon Rule 144 promulgated
under the Act to establish an exemption from registration requirements under Section 4(1) under the Act, but may nonetheless apply
Rule 144 constructively for the resale of such shares in the following manner: (a) provided that six months has elapsed since the
last sale under the registration statement, an underwriter or finder may resell the securities in accordance with the provisions
of Rule 144(c), (e), and (f), except for the notice requirement; (b) a purchaser of the shares from an underwriter receives restricted
securities unless the sale is made with an appropriate, current prospectus, or unless the sale is made pursuant to the conditions
contained in (a) above; (c) a purchaser of the shares from an underwriter who receives restricted securities may include the underwriter’s
holding period, provided that the underwriter or finder is not an affiliate of the issuer; and (d) if an underwriter transfers
the shares to its employees, the employees may tack the firm’s holding period for purposes of Rule 144(d), but they must
aggregate sales of the distributed shares with those of other employees, as well as those of the underwriter or finder, for a six-month
period from the date of the transfer to the employees. Holder and the Company also acknowledge that the Staff of the Division of
Corporation Finance of the SEC has advised in various no-action letters that the holding period associated with securities issued
without registration to a service provider commences upon the completion of the services, which the Company agrees and acknowledges
shall be the closing of the Offering, and that Rule 144(d)(3)(ii) provides that securities acquired from the issuer solely in exchange
for other securities of the same issuer shall be deemed to have been acquired at the same time as the securities surrendered for
conversion (which the Company agrees is the date of the initial issuance of this Unit Purchase Option). In the event that following
a request by Holder to transfer the Shares in accordance with Compliance & Disclosure Interpretation 528.04 counsel for the
Company reasonably concludes that Compliance & Disclosure Interpretation 528.04 no longer may be relied upon as a result of
changes in applicable laws, regulations, or interpretations of the SEC Division of Corporation Finance, or as a result of judicial
interpretations not known by the Company or its counsel on the date hereof (either, a “Registration Trigger Event”),
then the Company shall promptly, and in any event within five (5) business days following the request, provide written notice to
Holder of such determination. As a condition to giving such notice, the Company shall offer Holder a single demand registration
right pursuant to an agreement in form reasonably acceptable to the Holder; provided that notwithstanding anything to the contrary,
the obligations of the Company pursuant to this Section 2 shall terminate on the fifth anniversary of the effective date of the
Registration Statement pursuant to which the Offering is being made. In the absence of such conclusion by counsel for the Company,
the Company shall, upon request of Holder given no earlier than six months after the final closing of the Offering, instruct its
transfer agent to permit the transfer of such shares in accordance with Compliance & Disclosure Interpretation 528.04, provided
that Holder has provided such documentation as shall be reasonably be requested by the Company to establish compliance with the
conditions of Compliance & Disclosure Interpretation 528.04.

 

    	 	3	 

     

    

 

3.             Transfer.

 

(a)       Restrictions—General.
The securities evidenced by this Unit Purchase Option shall not 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, this Unit Purchase Option (or any securities underlying this Unit
Purchase Option) for a period of one hundred eighty (180) days following the Effective Date to anyone other than to any member
participating in the offering and the officers or partners thereof, if all securities so transferred remain subject to the lock-up
restriction set forth above for the remainder of the time period. In order to make any permitted assignment, the Holder must deliver
to the Company the assignment form attached hereto duly executed and completed, together with the Unit Purchase Option and payment
of all transfer taxes, if any, payable in connection therewith. The Company shall within three business days transfer this Unit
Purchase Option on the books of the Company and shall execute and deliver a new Unit Purchase Option or Unit Purchase Options
of like tenor to the appropriate assignee(s) expressly evidencing the right to purchase the aggregate number of Units purchasable
hereunder or such portion of such number as shall be contemplated by any such assignment.

 

(b)       Restrictions—Securities.
The securities evidenced by this Unit Purchase Option shall not be transferred
unless and until (i) the Company has received the opinion of counsel for the Holder that the securities may be transferred
pursuant to an exemption from registration under the Act and applicable state securities laws, the availability of which is established
to the reasonable satisfaction of the Company, or (ii) a registration statement or a post-effective amendment to the Registration
Statement relating to such securities has been filed by the Company and declared effective by the Securities and Exchange Commission
(the “Commission”) and compliance with applicable state securities law has been established.

 

4.             New
Unit Purchase Options to be Issued.

 

(a)       Partial
Exercise. Subject to the restrictions in Section 3 hereof, this Unit
Purchase Option may be exercised or assigned in whole or in part. In the event of the exercise or assignment hereof in part only,
upon surrender of this Unit Purchase Option for cancellation, together with the duly executed exercise or assignment form and
funds sufficient to pay any Exercise Price, the Company shall cause to be delivered to the Holder without charge a new Unit Purchase
Option of like tenor to this Unit Purchase Option in the name of the Holder evidencing the right of the Holder to purchase the
number of Units purchasable hereunder as to which this Unit Purchase Option has not been exercised or assigned.

 

    	 	4	 

     

    

 

(b)       Loss,
Theft, Destruction. Upon receipt by the Company of evidence satisfactory
to it of the loss, theft, destruction or mutilation of this Unit Purchase Option and of reasonably satisfactory indemnification
or the posting of a bond, the Company shall execute and deliver a new Unit Purchase Option of like tenor and date. Any such new
Unit Purchase Option executed and delivered as a result of such loss, theft, mutilation or destruction shall constitute a substitute
contractual obligation on the part of the Company.

 

5.             Adjustments.

 

(a)       Exercise
Price and Number of Securities. The Exercise Price and the number of Units
underlying the Unit Purchase Option shall be subject to adjustment from time to time as hereinafter set forth:

 

(i)       If
after the date hereof, and subject to the provisions of Section 5(c) below, the number of outstanding Shares is increased
by a stock dividend payable in Shares or by a split-up of Shares or other similar event, then, on the effective date thereof, the
number of Shares underlying each of the Units purchasable hereunder shall be increased in proportion to such increase in outstanding
shares. In such case, the number of Shares, and the exercise price applicable thereto, underlying the Warrants underlying each
of the Units purchasable hereunder shall be adjusted in accordance with the terms of the Warrants. For example, if the Company
declares a two-for-one stock dividend and immediately prior to such dividend this Unit Purchase Option is for the purchase of one
Unit at $10.00 per whole Unit (with each Warrant underlying the Units being exercisable for $12.00 per share), upon effectiveness
of the dividend, this Unit Purchase Option will be adjusted to allow for the purchase of one Unit at $10.00 per Unit, each Unit
entitling the holder to receive two Shares and two Warrants (each Warrant exercisable for $6.00 per share).

 

(ii)       If
after the date hereof, and subject to the provisions of Section 5(c), the number of outstanding Shares is decreased by a consolidation,
combination or reclassification of the Shares or other similar event, then, on the effective date thereof, the number of Shares
underlying each of the Units purchasable hereunder shall be decreased in proportion to such decrease in outstanding shares. In
such case, the number of Shares, and the exercise price applicable thereto, issuable upon exercise of the Warrants included in
each of the Units purchasable hereunder shall be adjusted in accordance with the terms of the Warrants. For example, if the Company
effects a one-for-two stock reverse stock split and immediately prior to such stock split this Unit Purchase Option is for the
purchase of one Unit at $10.00 per whole Unit (with each Warrant underlying the Units being exercisable for $12.00 per share),
upon effectiveness of the stock split, this Unit Purchase Option will be adjusted to allow for the purchase of one Unit at $10.00
per Unit, each Unit entitling the holder to receive 0.5 Shares and 0.5 Warrants (each Warrant exercisable for $24.00 per share).

(iii)       In
case of any reclassification or reorganization of the outstanding Shares other than a change covered by Section 5(a)(i) or
5(a)(ii) hereof or that solely affects the par value of such Shares, or in the case of any merger or consolidation of the Company
with or into another corporation (other than a consolidation or merger in which the Company is the continuing corporation and that
does not result in any reclassification or reorganization of the outstanding Shares), or in the case of any sale or conveyance
to another corporation or entity of the property of the Company as an entirety or substantially as an entirety in connection with
which the Company is dissolved, the Holder of this Unit Purchase Option shall have the right thereafter (until the expiration of
the right of exercise of this Unit Purchase Option) to receive upon the exercise hereof, for the same aggregate Exercise Price
payable hereunder immediately prior to such event plus the aggregate exercise price of the Shares underlying the Warrants immediately
prior to such event, the kind and amount of shares of stock or other securities or property (including cash) receivable upon such
reclassification, reorganization, merger or consolidation, or upon a dissolution following any such sale or transfer, by a Holder
of the number of Shares of the Company obtainable upon exercise of this Unit Purchase Option and the underlying Warrants immediately
prior to such event; and if any reclassification also results in a change in Shares covered by Section 5(a)(i) or 5(a)(ii),
then such adjustment shall be made pursuant to Sections 5(a)(i) or 5(a)(ii) and this Section 5(a)(iii). The provisions
of this Section 5(a)(iii) shall similarly apply to successive reclassifications, reorganizations, mergers or consolidations,
sales or other transfers.

 

(iv)       This
form of Unit Purchase Option need not be changed because of any change pursuant to this Section 5, and Unit Purchase Options
issued after such change may state the same Exercise Price and the same number of Units as are stated in the Unit Purchase Options
initially issued pursuant to this Agreement. The acceptance by any Holder of the issuance of new Unit Purchase Options reflecting
a required or permissive change shall not be deemed to waive any rights to an adjustment occurring after the Commencement Date
or the computation thereof.

 

(b)       Substitute
Unit Purchase Option. In case of any consolidation of the Company with,
or merger of the Company with, or merger of the Company into, another corporation (other than a consolidation or merger which
does not result in any reclassification or change of the outstanding Shares), the corporation formed by such consolidation or
merger shall execute and deliver to the Holder a supplemental Unit Purchase Option providing that the holder of each Unit Purchase
Option then outstanding or to be outstanding shall have the right thereafter (until the stated expiration of such Unit Purchase
Option) to receive, upon exercise of such Unit Purchase Option, the kind and amount of shares of stock and other securities and
property receivable upon such consolidation or merger, by a holder of the number of Shares of the Company for which such Unit
Purchase Option might have been exercised immediately prior to such consolidation, merger, sale or transfer. Such supplemental
Unit Purchase Option shall provide for adjustments which shall be identical to the adjustments provided in this Section 5.
The above provision of this Section 5 shall similarly apply to successive consolidations or mergers.

 

(c)       Fractional
Interests. The Company shall not be required to issue certificates representing
fractions of Shares or Warrants upon the exercise of the Unit Purchase Option, nor shall it be required to issue scrip or pay
cash in lieu of any fractional interests, it being the intent of the parties that all fractional interests shall be eliminated
by rounding any fraction up to the nearest whole number of Warrants, Shares or other securities, properties or rights.

 

    	 	6	 

     

    

 

6.             Reservation
and Listing. The Company shall at all times reserve and keep available out
of its authorized Shares, solely for the purpose of issuance upon exercise of the Warrants underlying the Unit Purchase Option,
such number of Shares or other securities, properties or rights as shall be issuable upon the conversion or exercise thereof.
The Company further covenants and agrees that upon exercise of the Warrants underlying the Unit Purchase Option and payment of
the respective Warrant exercise price therefor, all Shares and other securities issuable upon such exercise shall be duly and
validly issued, fully paid and non-assessable and not subject to preemptive rights of any stockholder. As long as the Unit Purchase
Option shall be outstanding, the Company shall use its best efforts to cause all (i) Units issuable upon exercise of the
Unit Purchase Option, and (ii) Shares issuable upon exercise of the Warrants included in the Units issuable upon exercise
of the Unit Purchase Option to be listed (subject to official notice of issuance) on all securities exchanges (or, if applicable
on the OTC Bulletin Board or any successor trading market) on which the Shares issued to the public in connection with the Offering
may then be listed and/or quoted; provided, however, that the Company shall only be required to comply with (i) above to the extent
the Units issued to the public in the Offering are still listed on a securities exchange.

 

7.             Certain
Notice Requirements.

 

(a)       Right
to Notice. Nothing herein shall be construed as conferring upon the Holders
the right to vote or consent as a stockholder for the election of directors or any other matter, or as having any rights whatsoever
as a stockholder of the Company. If, however, at any time prior to the expiration of the Unit Purchase Option and its exercise,
any of the events described in Section 7(b) shall occur, then, in one or more of said events, the Company shall give written
notice of such event at least fifteen days prior to the date fixed as a record date or the date of closing the transfer books
for the determination of the stockholders entitled to such dividend, distribution, conversion or exchange of securities or subscription
rights, or entitled to vote on such proposed dissolution, liquidation, winding up or sale. Such notice shall specify such record
date or the date of the closing of the transfer books, as the case may be. Notwithstanding the foregoing, the Company shall deliver
to each Holder a copy of each notice given to the other stockholders of the Company with respect to the events enumerated in Section
7(b) at the same time and in the same manner that such notice is given to all stockholders, even if less than fifteen days.

 

(b)       Enumerated
Events. The Company shall be required to give the notice described in this
Section 7 upon one or more of the following events: (i) if the Company shall take a record of the holders of its Shares
for the purpose of entitling them to receive a dividend or distribution payable otherwise than in cash, or a cash dividend or
distribution payable otherwise than out of retained earnings, as indicated by the accounting treatment of such dividend or distribution
on the books of the Company, or (ii) the Company shall offer to all the holders of its Shares any additional shares of capital
stock of the Company or securities convertible into or exchangeable for shares of capital stock of the Company, or any option,
right or warrant to subscribe therefor, or (iii) a dissolution, liquidation or winding up of the Company (other than in connection
with a consolidation or merger) or a sale of all or substantially all of its property, assets and business shall be proposed.

 

    	 	7	 

     

    

 

(c)       Change
in Exercise Price. The Company shall, promptly after an event requiring
a change in the Exercise Price pursuant to Section 5 hereof, send notice to the Holders of such event and change (the “Price
Notice”). The Price Notice shall describe the event causing the change and the method of calculating same and shall
be certified as being true and accurate by the Company’s President and Chief Financial Officer.

 

(d)       Notice
Delivery. All notices, requests, consents and other communications under
this Unit Purchase Option shall be in writing and shall be deemed to have been duly made when hand delivered, or mailed by express
mail or private courier service: (i) If to the registered Holder of the Unit Purchase Option, to the address of such Holder
as shown on the books of the Company, or (ii) If to the Company, to the following address or to such other address as the
Company may designate by notice to the Holders:

 

NanoVibronix, Inc.

Nesher, Israel 36651

Attn: Chief Executive Officer

 

8.             Registration
Rights.

 

(a)       Covenant
to Register the Shares.

 

(i)       If
requested in writing by the Holder, the Company agrees to register for resale the Shares underlying the Units (including the Shares
underlying the Warrants included in the Units) (collectively, the “Registrable Securities”); provided, however,
that Registrable Securities shall not include any Shares, the offer and sale of which have previously been registered or which
have been sold to the public either pursuant to a registration statement or Rule 144, or which are eligible for resale pursuant
to Rule 144 of the Act without volume or manner-of-sale restriction pursuant to Rule 144 of the Act and without the requirement
for the Company to be in compliance with the current public information requirements under Rule 144(c)(1) of the Act. The Holder
may only make one demand request pursuant to this Section 8(a). The Company will use commercially reasonable efforts to file a
short-form registration statement on Form S-3 (the “Form S-3”) with the Commission covering the resale of the
Registrable Securities pursuant to Rule 415(a)(1)(i) within thirty (30) days after the Company is eligible to use such Form S-3.
The Company shall bear all fees and expenses attendant to the registration of the Registrable Securities pursuant to this Section.
The Company agrees to use its commercially reasonable efforts to cause the Form S-3 filing required herein to become effective
promptly. Notwithstanding anything to the contrary, the obligations of the Company pursuant to this Section 8 shall terminate on
the fifth anniversary of the effective date of the Registration Statement pursuant to which the Offering is being made.

 

    	 	8	 

     

    

 

(b)       General
Terms.

 

(i)       Indemnification.
The Company shall indemnify the Holder(s) of the Registrable Securities to be sold pursuant to any registration statement hereunder
and each person, if any, who controls such Holders within the meaning of Section 15 of the Act or Section 20 (a) of the Securities
Exchange Act of 1934, as amended (“Exchange Act”), against all loss, claim, damage, expense or liability (including
all reasonable attorneys’ fees and other expenses reasonably incurred in investigating, preparing or defending against any
claim whatsoever) to which any of them may become subject under the Act, the Exchange Act or otherwise, arising from such registration
statement but only to the same extent and with the same effect as the provisions pursuant to which the Company has agreed to indemnify
Dawson contained in the Underwriting Agreement between Dawson and the Company, dated as of [●], 2017 (“Underwriting
Agreement”). The Holder(s) of the Registrable Securities to be sold pursuant to such registration statement, and their
successors and assigns, shall severally, and not jointly, indemnify the Company, against all loss, claim, damage, expense or liability
(including all reasonable attorneys’ fees and other expenses reasonably incurred in investigating, preparing or defending
against any claim whatsoever) to which they may become subject under the Act, the Exchange Act or otherwise, arising from information
furnished by or on behalf of such Holders, or their successors or assigns, in writing, for specific inclusion in such registration
statement to the same extent and with the same effect as the provisions contained in the Underwriting Agreement pursuant to which
Dawson has agreed to indemnify the Company.

 

(ii)       Exercise
of Unit Purchase Option. Nothing contained in this Unit Purchase Option shall be construed as requiring the Holder(s) to exercise
their Unit Purchase Option prior to or after the initial filing of any registration statement or the effectiveness thereof.

 

(iii)       Documents
Delivered to Holders. The Company shall deliver promptly to each Holder participating in the offering requesting the correspondence
and memoranda described below and to the managing underwriter, if any, copies of all correspondence between the Commission and
the Company, its counsel or auditors and all memoranda relating to discussions with the Commission or its staff with respect to
the registration statement and permit each Holder and underwriter to do such investigation, upon reasonable advance notice, with
respect to information contained in or omitted from the registration statement as it deems reasonably necessary to comply with
applicable securities laws or rules of FINRA. Such investigation shall include access to books, records and properties and opportunities
to discuss the business of the Company with its officers and independent auditors, all to such reasonable extent and at such reasonable
times, during normal business hours, as any such Holder shall reasonably request.

 

(iv)       Underwriting
Agreement. The Company shall enter into an underwriting agreement with the managing underwriter(s), if any, selected by any
Holders whose Registrable Securities are being registered pursuant to this Section 8, which managing underwriter shall be reasonably
satisfactory to the Company. Such agreement shall be reasonably satisfactory in form and substance to the Company, each Holder
and such managing underwriters, and shall contain such representations, warranties and covenants by the Company and such other
terms as are customarily contained in agreements of that type used by the managing underwriter. The Holders shall be parties to
any underwriting agreement relating to an underwritten sale of their Registrable Securities. Such Holders shall not be required
to make any representations or warranties to or agreements with the Company or the underwriters except as they may relate to such
Holders, their Shares and their intended methods of distribution.

 

    	 	9	 

     

    

 

(v)       Documents
to be Delivered by Holder(s). Each of the Holder(s) participating in any of the foregoing offerings shall furnish to the Company
a completed and executed questionnaire provided by the Company requesting information customarily sought of selling security holders.

 

(vi)       Damages.
Should the registration or the effectiveness thereof required by Section 8 hereof be delayed by the Company or the Company otherwise
fails to comply with such provisions, the Holder(s) shall, in addition to any other legal or other relief available to the Holder(s),
be entitled to obtain specific performance or other equitable (including injunctive) relief against the threatened breach of such
provisions or the continuation of any such breach, without the necessity of proving actual damages and without the necessity of
posting bond or other security.

 

9.             Miscellaneous.

 

(a)       Amendments.
The Company and Dawson may from time to time supplement or amend this Unit
Purchase Option without the approval of any of the Holders in order to cure any ambiguity, to correct or supplement any provision
contained herein that may be defective or inconsistent with any other provisions herein, or to make any other provisions in regard
to matters or questions arising hereunder that the Company and Dawson may deem necessary or desirable and that the Company and
Dawson deem shall not adversely affect the interest of the Holders. All other modifications or amendments shall require the written
consent of and be signed by the party against whom enforcement of the modification or amendment is sought.

 

(b)       Headings.
The headings contained herein are for the sole purpose of convenience of
reference, and shall not in any way limit or affect the meaning or interpretation of any of the terms or provisions of this Unit
Purchase Option.

 

(c)       Entire
Agreement. This Unit Purchase Option (together with the other agreements
and documents being delivered pursuant to or in connection with this Unit Purchase Option) constitutes the entire agreement of
the parties hereto with respect to the subject matter hereof, and supersedes all prior agreements and understandings of the parties,
oral and written, with respect to the subject matter hereof.

 

(d)       Binding
Effect. This Unit Purchase Option shall inure solely to the benefit of,
and shall be binding upon, the Holder and the Company and their permitted assignees, respective successors, legal representative
and assigns, and no other person shall have or be construed to have any legal or equitable right, remedy or claim under or in
respect of or by virtue of this Unit Purchase Option or any provisions herein contained.

 

    	 	10	 

     

    

 

(e)       Governing
Law. This Unit Purchase Option shall be governed by and construed and enforced
in accordance with the laws of the State of New York, without giving effect to conflict of laws. The Company hereby agrees that
any action, proceeding or claim against it arising out of, or relating in any way to this Unit Purchase Option shall be brought
and enforced in the courts of the State of New York or of the United States of America for the Southern District of New York,
and irrevocably submits to such jurisdiction, which jurisdiction shall be exclusive. The Company hereby waives any objection to
such exclusive jurisdiction and that such courts represent an inconvenient forum. Any process or summons to be served upon the
Company may be served by transmitting a copy thereof by registered or certified mail, return receipt requested, postage prepaid,
addressed to it at the address set forth in Section 7 hereof. Such mailing shall be deemed personal service and shall be
legal and binding upon the Company in any action, proceeding or claim. The Company and the Holder agree that the prevailing party(ies)
in any such action shall be entitled to recover from the other party(ies) all of its reasonable attorneys’ fees and expenses
relating to such action or proceeding and/or incurred in connection with the preparation therefor.

 

(f)       Waivers.
The failure of the Company or the Holder to at any time enforce any of the
provisions of this Unit Purchase Option shall not be deemed or construed to be a waiver of any such provision, nor to in any way
affect the validity of this Unit Purchase Option or any provision hereof or the right of the Company or any Holder to thereafter
enforce each and every provision of this Unit Purchase Option. No waiver of any breach, non-compliance or non-fulfillment of any
of the provisions of this Unit Purchase Option shall be effective unless set forth in a written instrument executed by the party
or parties against whom or which enforcement of such waiver is sought; and no waiver of any such breach, non-compliance or non-fulfillment
shall be construed or deemed to be a waiver of any other or subsequent breach, non-compliance or non-fulfillment.

 

(g)       Counterparts.
This Unit Purchase Option may be executed in one or more counterparts, and
by the different parties hereto in separate counterparts, each of which shall be deemed to be an original, but all of which taken
together shall constitute one and the same agreement, and shall become effective when one or more counterparts has been signed
by each of the parties hereto and delivered to each of the other parties hereto. Such counterparts may be delivered by facsimile
transmission or other electronic transmission.

 

(h)       Exchange
Agreement. As a condition of the Holder’s receipt and acceptance of
this Unit Purchase Option, Holder agrees that, at any time prior to the complete exercise of this Unit Purchase Option by Holder,
if the Company and Dawson enter into an agreement (the “Exchange Agreement”) pursuant to which they agree that
all outstanding Unit Purchase Options will be exchanged for securities or cash or a combination of both, then Holder shall agree
to such exchange and become a party to the Exchange Agreement.
