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 (the “Aggregate Exercise

deliver any objection to any Notice of Exercise within one (1) Trading Day of receipt of such notice. The Holder and any assignee,

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.

the nominal exercise price of $[ ] 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, including in the event this Warrant shall not have been exercised prior
to the Termination Date. The remaining unpaid exercise price per share of Common Stock under this Warrant shall be $[ ], subject
to adjustment hereunder (the “Exercise Price”).


 


c) Cashless
Exercise. This Warrant may also be exercised, in whole or in part, at any 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)

	 	(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.



 








    3


     


    

 


“Bid
Price” means, for any date, the bid price determined by the first of the following clauses that applies: (i) for such
security on the principal market on which the Company’s Common Stock trades as reported by Bloomberg as of such time of
determination, or, if the principal market is not the principal securities exchange or trading market for such security, the bid
price of such security on the principal securities exchange or trading market where such security is listed or traded as reported
by Bloomberg as of such time of determination, or if the foregoing does not apply, (ii) the bid price of such security in the
over-the-counter market on the electronic bulletin board for such security as reported by Bloomberg as of such time of determination,
or, if no bid price is reported for such security by Bloomberg as of such time of determination, (iii) the average of the bid
prices of any market makers for such security as reported on The Pink Open Market as of such time of determination, or if the
Bid Price cannot be calculated for a security as of the particular time of determination on any of the foregoing bases, (iv) the
Bid Price of such security as of such time of determination shall be the fair market value as mutually determined by the Company
and the Holder. If the Company and the Holder are unable to agree upon the fair market value of such security, then such dispute
shall be resolved by an independent, reputable investment bank selected by the Company and approved by the Holders (such approval
not to be unreasonably withheld or delayed). All such determinations shall be appropriately adjusted for any stock dividend, stock
split, stock combination or other similar transaction during such period.


 


“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 on The Pink Open Market (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.


 


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

d) Mechanics
of Exercise.


 


i. Delivery
of Warrant Shares Upon Exercise. The Company shall cause the Warrant Shares purchased hereunder to be transmitted by the Transfer
Agent to the Holder by crediting the account of the Holder’s or its designee’s balance account with The Depository
Trust Company through its Deposit or Withdrawal at Custodian system (“DWAC”) if the Company is then a participant
in such system and either (A) there is an effective registration statement permitting the issuance of the Warrant Shares to or
resale of the Warrant Shares by the Holder or (B) this Warrant is being exercised via cashless exercise, and otherwise by physical
delivery of a certificate, registered in the Company’s share register in the name of the Holder or its designee, for the
number of Warrant Shares to which the Holder is entitled pursuant to such exercise to the address specified by the Holder in the
Notice of Exercise by, (x) so long as the Holder delivers the Aggregate Exercise Price (or notice of a cashless exercise) on or
prior to the first (1st) Trading Day following the date on which the Notice of Exercise has been delivered to the Company, then
on or prior to the second (2nd) Trading Day following the date on which the Notice of Exercise has been delivered to the Company,
or, (y) if the Holder does not deliver the Aggregate Exercise Price (or notice of a cashless exercise) on or prior to the first
(1st) Trading Day following the date on which the Notice of Exercise has been delivered to the Company, then on or prior to the
first (1st) Trading Day following the date on which the Aggregate Exercise Price (or notice of a cashless exercise) is delivered
(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 by the Warrant Share Delivery Date provided that the Aggregate
Exercise Price is received within two (2) Trading Days 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 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. 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 Stock 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.


 




    5


     


    




 


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. 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.


 


iii. Rescission
Rights. If the Company fails to transmit or 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, 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.


 




    6


     


    




 


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


 


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


 


vii. Closing
of Books. The Company will not close its 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. Notwithstanding anything to the contrary contained herein, the Company shall not effect the exercise
of any portion of this Warrant, and the Holder shall not have the right to exercise any portion of this Warrant, pursuant to the
terms and conditions of this Warrant and any such exercise shall be null and void and treated as if never made, to the extent
that after giving effect to such 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”)
collectively would beneficially own in excess of [4.99%/9.99%[1]] (the “Beneficial Ownership Limitation”)
of the number of shares of Common Stock outstanding immediately after giving effect to such exercise. For purposes of the foregoing
sentence, the aggregate number of shares of Common Stock beneficially owned by the Holder and the other Attribution Parties shall
include the number of shares of Common Stock held by the Holder and all other Attribution Parties plus the number of shares of
Common Stock issuable upon exercise of this Warrant with respect to which the determination of such sentence is being made, but
shall exclude the number of shares of Common Stock which would be issuable upon (A) exercise of the remaining, unexercised portion
of this Warrant beneficially owned by the Holder or any of the other Attribution Parties and (B) exercise or conversion of the
unexercised or unconverted portion of any other securities of the Company (including, without limitation, any convertible notes
or convertible preferred stock or warrants) beneficially owned by the Holder or any other Attribution Party subject to a limitation
on conversion or exercise analogous to the limitation contained in this Section 2(e). For purposes of this Section 2(e), beneficial
ownership shall be calculated in accordance with Section 13(d) of the Securities Exchange Act of 1934, as amended (the “1934
Act”).


 




    7


     


    




 


For
purposes of this Warrant, in determining the number of outstanding shares of Common Stock the Holder may acquire upon the exercise
of this Warrant without exceeding the Beneficial Ownership Limitation, the Holder may rely on the number of outstanding shares
of Common Stock as reflected in (x) the Company's most recent Annual Report on Form 10-K, Quarterly Report on Form 10-Q, and Current
Reports on Form 8-K or other public filing with the Securities and Exchange Commission (the “SEC” or “Commission”),
as the case may be, (y) a more recent public announcement by the Company or (3) any other written notice by the Company or the
Transfer Agent setting forth the number of shares of Common Stock outstanding (the “Reported Outstanding Share Number”).
If the Company receives an Notice of Exercise from the Holder at a time when the actual number of outstanding shares of Common
Stock is less than the Reported Outstanding Share Number, the Company shall (i) notify the Holder in writing of the number of
shares of Common Stock then outstanding and, to the extent that such Notice of Exercise would otherwise cause the Holder's beneficial
ownership, as determined pursuant to this Section 2(e), to exceed the Beneficial Ownership Limitation, the Holder must notify
the Company of a reduced number of Warrant Shares to be purchased pursuant to such Notice of Exercise (the number of shares by
which such purchase is reduced, the “Reduction Shares”) and (ii) as soon as reasonably practicable, the Company
shall return to the Holder any exercise price paid by the Holder for the Reduction Shares. For any reason at any time, upon the
written or oral request of the Holder, the Company shall within one (1) Business Day confirm orally and in writing or by electronic
mail 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 and any other Attribution Party since the date as of which the Reported Outstanding Share Number was reported.


 


In
the event that the issuance of shares of Common Stock to the Holder upon exercise of this Warrant results in the Holder and the
other Attribution Parties being deemed to beneficially own, in the aggregate, more than the Beneficial Ownership Limitation of
the number of outstanding shares of Common Stock (as determined under Section 13(d) of the 1934 Act), the number of shares so
issued by which the Holder's and the other Attribution Parties' aggregate beneficial ownership exceeds the Beneficial Ownership
Limitation (the “Excess Shares”) shall be deemed null and void and shall be cancelled ab initio, and the Holder
shall not have the power to vote or to transfer the Excess Shares. As soon as reasonably practicable after the issuance of the
Excess Shares has been deemed null and void, the Company shall return to the Holder the exercise price paid by the Holder for
the Excess Shares.


 




    8


     


    




 


Upon
delivery of a written notice to the Company, the Holder may from time to time increase or decrease the Beneficial Ownership Limitation
to any other percentage not in excess of 9.99% as specified in such notice; provided, however, that (i) any such
increase in the Beneficial Ownership Limitation will not be effective until the sixty-first (61st) day after such notice
is delivered to the Company and (ii) any such increase or decrease will apply only to the Holder and the other Attribution Parties
and not to any other holder of warrants that is not an Attribution Party of the Holder.


 


For
purposes of clarity, the shares of Common Stock issuable pursuant to the terms of this Warrant in excess of the Beneficial Ownership
Limitation shall not be deemed to be beneficially owned by the Holder for any purpose including for purposes of Section 13(d)
or Rule 16a-1(a)(1) of the 1934 Act. No prior inability to exercise this Warrant pursuant to this section shall have any effect
of the applicability of the provisions of this section with respect to any subsequent determination of exercisability. 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 the extent necessary to correct this paragraph or any portion of this paragraph which may be defective or inconsistent
with the intended beneficial ownership limitation contained in this Section 2(e) or to make changes or supplements necessary or
desirable to properly give effect to such limitation. The limitation contained in this Section 2(e) may not be waived and shall
apply to a successor holder of this Warrant. The Holder acknowledges that the Company may rely on the information set forth in
the Notice of Exercise, and shall not be required to independently verify whether or not an exercise would trigger the provisions
of this section.


 


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 a class or series of shares of its 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 at the close of business on the effective
date of such transaction.


 




    9


     


    




 


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 options, warrants or other securities convertible into Common Stock or rights to purchase stock, warrants, securities
or other property pro rata to all the record holders of any class of shares of Common Stock (the “Purchase Rights”),
then the Holder will be entitled to acquire, upon the terms applicable to such Purchase Rights, the aggregate Purchase Rights
which the Holder could have acquired if the Holder had held the number of shares of Common Stock acquirable upon complete exercise
of this Warrant (without regard to any limitations on exercise hereof, including without limitation, the Beneficial Ownership
Limitation) immediately before the date on which a record is taken for the grant, issuance or sale of such Purchase Rights, or,
if no such record is taken, the date as of which the record holders of shares of Common Stock are to be determined for the grant,
issue or sale of such Purchase Rights (provided, however, that to the extent that the Holder's right to participate
in any such Purchase Right would result in the Holder and the other Attribution Parties exceeding the Beneficial Ownership Limitation,
then the Holder shall not be entitled to participate in such Purchase Right to such extent (and shall not be entitled to beneficial
ownership of such shares of Common Stock as a result of such Purchase Right (and beneficial ownership) 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 shares of Common Stock, by way of return of capital
or otherwise (including, without limitation, any distribution of cash, stock (not including shares of Common Stock of the Company)
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 shares of Common Stock acquirable upon complete exercise of this
Warrant (without regard to any limitations or restrictions on exercise hereof, including without limitation, the Beneficial Ownership
Limitation) immediately before the date on which a record is taken for such Distribution, or, if no such record is taken, the
date as on 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 and the other Attribution Parties exceeding the Beneficial Ownership Limitation, then the Holder shall only be entitled
to participate in such Distribution to the extent of the Beneficial Ownership Limitation (and shall not be entitled to beneficial
ownership of such shares of Common Stock as a result of such Distribution (and beneficial ownership) to the extent of any such
excess) and the portion of such Distribution shall be held in abeyance for the benefit of the Holder until such time or times,
if ever, as its right thereto would not result in the Holder and the other Attribution Parties exceeding the Beneficial Ownership
Limitation, at which time the Holder shall be granted such Distribution (and any Distributions declared or made on such initial
Distribution or on any subsequent Distribution held similarly in abeyance) to the same extent as if there had been no such limitation).


 




    10


     


    




 


d) Fundamental
Transaction. Upon the occurrence of any Fundamental Transaction (defined below), the Successor Entity (defined below) shall
succeed to, and be substituted for the Company (so that from and after the date of such Fundamental Transaction, each and every
provision of this Warrant referring to the “Company” shall instead refer to the Successor Entity), and the Successor
Entity may exercise every prior right and power of the Company and shall assume all prior obligations of the Company under this
Warrant with the same effect as if the Successor Entity had been named as the Company in this Warrant and the adjustments in the
following sentence had occurred. On or prior to the consummation of each Fundamental Transaction, the Successor Entity shall deliver
to the Holder confirmation that (and Holders agrees that) there shall be issued upon exercise of this Warrant at any time after
the consummation of the Fundamental Transaction, in lieu of the shares of Common Stock (or other securities, cash, assets or other
property purchasable upon the exercise of this Warrant prior to such Fundamental Transaction), such shares of stock, securities,
cash, assets or any other property whatsoever (including warrants or other purchase or subscription rights), which for purposes
of clarification may continue to be shares of Common Stock, if any, that the Holder would have been entitled to receive upon the
happening of such Fundamental Transaction or the record, eligibility or other determination date for the event resulting in such
Fundamental Transaction, had this Warrant been exercised immediately prior to such Fundamental Transaction or the record, eligibility
or other determination date for the event resulting in such Fundamental Transaction (without regard to any limitations on the
exercise of this Warrant), as adjusted in accordance with the provisions of this Warrant. 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 consideration it receives upon any exercise of this Warrant following such Fundamental Transaction.


 


“Fundamental
Transaction” means (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

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

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). a “Successor Entity” means any successor entity in a Fundamental Transaction
in which the Company is not the survivor.

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 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.


 


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 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. 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.


 


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


 


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


 


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 the rights of a Holder to receive Warrant Shares on a “cashless exercise,”
and to receive the cash payments contemplated pursuant to Sections 2(d)(i) and 2(d)(iv), in no event will the Company be required
to net cash settle a Warrant exercise.


 




    13


     


    

  


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


 


d) Authorized
Shares.


 


The
Company 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).


 


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.


 




    14


     


    










 


e) Governing
Law. All questions concerning the construction, validity, enforcement and interpretation of this Warrant shall be governed
by and construed and enforced in accordance with the internal laws of the State of New York, without regard to the principles
of conflicts of law thereof. Each party agrees that all legal proceedings concerning the interpretations, enforcement and defense
of the transactions contemplated by this Warrant (whether brought against a party hereto or their respective affiliates, directors,
officers, shareholders, partners, members, employees or agents) shall be commenced exclusively in the state and federal courts
sitting in the City of New York. Each party hereby irrevocably submits to the exclusive jurisdiction of the state and federal
courts sitting in the City of New York, Borough of Manhattan for the adjudication of any dispute hereunder or in connection herewith
or with any transaction contemplated hereby or discussed herein, and hereby irrevocably waives, and agrees not to assert in any
suit, action or proceeding, any claim that it is not personally subject to the jurisdiction of any such court, that such suit,
action or proceeding is improper or is an inconvenient venue for such proceeding. Each party hereby irrevocably waives personal
service of process and consents to process being served in any such suit, action or proceeding by mailing a copy thereof via registered
or certified mail or overnight delivery (with evidence of delivery) to such party at the address in effect for notices to it under
this Warrant and agrees that such service shall constitute good and sufficient service of process and notice thereof. Nothing
contained herein shall be deemed to limit in any way any right to serve process in any other manner permitted by law. If either
party shall commence an action, suit or proceeding to enforce any provisions of this Warrant, the prevailing party in such action,
suit or proceeding shall be reimbursed by the other party for their reasonable attorneys’ fees and other costs and expenses
incurred with the investigation, preparation and prosecution of such action or proceeding.


 


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


 


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


 




    15


     


    




 


h) Notices.
Any and all notices or other communications or deliveries to be provided by the holders hereunder including, without limitation,
any Notice of Exercise, shall be in writing and delivered personally, by facsimile or e-mail, or sent by a nationally recognized
overnight courier service, addressed to the Company, at [__], Attention: [___], email address: [___], facsimile: [__], or such
other facsimile number, email address or address as the Company may specify for such purposes by notice to the Holders. Any and
all notices or other communications or deliveries to be provided by the Company hereunder shall be in writing and delivered personally,
by facsimile or e-mail, or sent by a nationally recognized overnight courier service addressed to each Holder at the facsimile
number, e-mail address or address of such Holder appearing on the books of the Company. Any notice or other communication or deliveries
hereunder shall be deemed given and effective on the earliest of (i) the time of transmission, if such notice or communication
is delivered via facsimile at the facsimile number or via e-mail at the e-mail address set forth in this Section prior to 5:30
p.m. (New York City time) on any date, (ii) the next Trading Day after the date of transmission, if such notice or communication
is delivered via facsimile at the facsimile number or via e-mail at the e-mail address set forth in this Section on a day that
is not a Trading Day or later than 5:30 p.m. (New York City time) on any Trading Day, (iii) the second Trading Day following the
date of mailing, if sent by U.S. nationally recognized overnight courier service, or (iv) upon actual receipt by the party to
whom such notice is required to be given. To the extent that any notice provided hereunder constitutes, or contains, material,
non-public information regarding the Company or any subsidiaries, the Company shall simultaneously file such notice with the Commission
pursuant to a Current Report on Form 8-K


 


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


 


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 record
Holders of Warrants issued under the Purchase Agreement covering 66% of the number of Warrant Shares into which the Warrants are
then exercisable; provided that amendments to the Exercise Price, Expiration Date, or number of Warrant Shares into which the
Warrants are then exercisable, would require the consent of the then Holder of the Warrants that are being so amended.


 


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.
