	Warrant
    Shares: [xxxxxxx]	Initial
    Exercise Date: [Month Day, 2018]
	 	Issue
    Date: [Month Day, 2018]


 


THIS
COMMON STOCK PURCHASE WARRANT (the “Warrant”) certifies that, for value received, [HOLDER] or its assigns (the
“Holder”) is entitled, upon the terms and subject to the limitations on exercise and the conditions hereinafter
set forth, at any time on or after [Month Day, 2018] (the “Initial Exercise Date”) and on or prior to the close
of business on the five year anniversary of the Initial Exercise Date (the “Termination Date”) but not thereafter,
to subscribe for and purchase from Pressure BioSciences, Inc., a Massachusetts corporation (the “Company”),
up to [xxxxxxx] shares (as subject to adjustment hereunder, the “Warrant Shares”) of Common Stock. The purchase
price of one share of Common Stock under this Warrant shall be equal to the Exercise Price, as defined in Section 2(b).


 


Section
1. Definitions. Capitalized terms used and not otherwise defined herein shall have the meanings set forth in that certain
Securities Purchase Agreement (the “Purchase Agreement”), dated of even date herewith among the Company and
the purchaser’s signatory thereto.


 


Section
2. Exercise.


 


a)
Exercise of Warrant. Exercise of the purchase rights represented by this Warrant may be made, in whole or in part, at any
time or times on or after the Initial Exercise Date and on or before the Termination Date by delivery to the Company (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 of the Notice of Exercise form annexed hereto
and within three (3) Trading Days of the date said Notice of Exercise is delivered to the Company, the Company shall have received
payment of the aggregate Exercise Price of the shares thereby purchased by wire transfer or cashier’s check drawn on a United
States bank or, if available, pursuant to the cashless exercise procedure specified in Section 2(c) below. No ink-original Notice
of Exercise shall be required, nor shall any medallion guarantee (or other type of guarantee or notarization) of any Notice of
Exercise form be required. Notwithstanding anything herein to the contrary, the Holder shall not be required to physically surrender
this Warrant to the Company until the Holder has purchased all of the Warrant Shares available hereunder and the Warrant has been
exercised in full, in which case, the Holder shall surrender this Warrant to the Company for cancellation within three (3) Trading
Days of the date the final Notice of Exercise is delivered to the Company. Partial exercises of this Warrant resulting in purchases
of a portion of the total number of Warrant Shares available hereunder shall have the effect of lowering the outstanding number
of Warrant Shares purchasable hereunder in an amount equal to the applicable number of Warrant Shares purchased. The Holder and
the Company shall maintain records showing the number of Warrant Shares purchased and the date of such purchases. The Company
shall deliver any objection to any Notice of Exercise Form within two (2) Business Days of receipt of such notice. The Holder
and any assignee, by acceptance of this Warrant, acknowledge and agree that, by reason of the provisions of this paragraph, following
the purchase of a portion of the Warrant Shares hereunder, the number of Warrant Shares available for purchase hereunder at any
given time may be less than the amount stated on the face hereof.


 






    	 	 	 



     


    

 


b)
Exercise Price. The exercise price per share of the Common Stock under this Warrant shall be $3.50, subject to adjustment
hereunder (the “Exercise Price”).


 


c)
Cashless Exercise. This Warrant may be exercised, in whole or in part, by means of a “cashless exercise” in
accordance with this Section 2(c), if at any time after the earlier of: (i) the 180 day anniversary of the date of the Purchase
Agreement; and (ii) the completion of the then-applicable holding period required by Rule 144, or any successor provision then
in effect, there is no effective Registration Statement registering, or no current prospectus available for, the resale of the
Warrant Shares by the Holder, then this Warrant may be exercised, in whole or in part, at such time by means of a “cashless
exercise.” Pursuant to a cashless exercise, the Holder shall be entitled to receive a number of Warrant Shares equal to
the quotient obtained by utilizing the formula below. The Company is not required to pay cash if it can only deliver upon settlement
of a “cashless exercise”, Warrant Shares that are not registered under the Securities Act. The formula consists of
dividing [(A-B) x (X)] by (A)], where:


 


	 	(A)	=
    the VWAP on the Trading Day immediately preceding the date on which Holder elects to exercise this Warrant by means of a “cashless
    exercise,” as set forth in the applicable Notice of Exercise;
	 	 	 
	 	(B)	=
    the Exercise Price of this Warrant, as adjusted hereunder; and
	 	 	 
	 	(X)
    	=
    the number of Warrant Shares that would be issuable upon exercise of this Warrant in accordance with the terms of this Warrant
    if such exercise were by means of a cash exercise rather than a cashless exercise.


 


d)
Mechanics of Exercise.


 


i.       Delivery
of Warrant Shares Upon Exercise. By the date that is two (2) Trading Days after the latest of (A) the delivery to the Company
of the Notice of Exercise and (B) surrender of this Warrant (if required) (such date, the “Registered Warrant Share Delivery
Date”), Warrant Shares purchased hereunder shall be transmitted by the Transfer Agent to the Holder by crediting the
account of the Holder’s prime broker with The Depository Trust Company through its Deposit or Withdrawal at Custodian system
(“DWAC”) if the Company is then a participant in such system and there is an effective registration statement
permitting the issuance of the Warrant Shares to or resale of the Warrant Shares by the Holder. . By the date that is three
(3) Trading Days after the latest of (A) the delivery to the Company of the Notice of Exercise and (B) surrender of this Warrant
(if required) (such date, the “144 Warrant Share Delivery Date”), Warrant Shares purchased hereunder shall
be transmitted by the Transfer Agent to the Holder by crediting the account of the Holder’s prime broker with The Depository
Trust Company through its DWAC system if the Company is then a participant in such system and the shares are eligible for resale
by the Holder without the holding period, volume or manner-of-sale limitations pursuant to Rule 144. If the Warrant Shares are
not registered and not eligible for resale pursuant to Rule 144 the Warrant Shares shall be delivered by physical delivery to
the address specified by the Holder in the Notice of Exercise by the date that is three (3) Trading Days after the latest of (A)
the delivery to the Company of the Notice of Exercise and (B) surrender of this Warrant (if required) (such date, the “Physical
Warrant Share Delivery Date”). The Warrant Shares shall be deemed to have been issued, and Holder or any other person
so designated to be named therein shall be deemed to have become a holder of record of such shares for all purposes, as of the
date the Warrant has been exercised, with payment to the Company of the Exercise Price (or by cashless exercise, if permitted)
and all taxes required to be paid by the Holder, if any, pursuant to Section 2(d)(vi) prior to the issuance of such shares, having
been paid.


 


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.


 






    	 	2	 



     


    

 


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 Registered Warrant Share Delivery Date, the 144 Warrant Share Delivery Date, or the Physical Warrant Share Delivery
Date (as applicable), then the Holder will have the right to rescind such exercise provided that notice of such rescission is
provided to the Company prior to the Warrant Shares being delivered to the Holder.


 


iv.       Compensation
for Buy-In on Failure to Timely Deliver Warrant Shares Upon Exercise. In addition to any other rights available to the Holder,
if the Company fails to cause the Transfer Agent to transmit to the Holder the Warrant Shares pursuant to an exercise on or before
the Registered Warrant Share Delivery Date or the 144 Warrant Share Delivery Date (as applicable), 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 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.


 






    	 	3	 



     


    

 


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 affect any exercise of this Warrant, and a Holder shall not
have the right to exercise any portion of this Warrant, pursuant to Section 2 or otherwise, to the extent that after giving effect
to such issuance after exercise as set forth on the applicable Notice of Exercise, the Holder (together with the Holder’s
Affiliates, and any other Persons acting as a group together with the Holder or any of the Holder’s Affiliates), would beneficially
own in excess of the Beneficial Ownership Limitation (as defined below). For purposes of the foregoing sentence, the number of
shares of Common Stock beneficially owned by the Holder and its Affiliates shall include the number of shares of Common Stock
issuable upon exercise of this Warrant with respect to which such determination is being made, but shall exclude the number of
shares of Common Stock which are issuable upon: (i) exercise of the remaining, nonexercised portion of this Warrant beneficially
owned by the Holder or any of its Affiliates; and (ii) exercise or conversion of the unexercised or nonconverted portion of any
other securities of the Company subject to a limitation on conversion or exercise analogous to the limitation contained herein
(including, without limitation, any other Warrants) beneficially owned by the Holder or any of its Affiliates. 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 of which portion of this Warrant is exercisable shall be in the sole discretion
of the Holder, and the submission of a Notice of Exercise shall be deemed to be the Holder’s determination of whether this
Warrant is exercisable (in relation to other securities owned by the Holder together with any Affiliates) and of which portion
of this Warrant is exercisable, in each case subject to the Beneficial Ownership Limitation. To ensure compliance with this restriction,
the Holder will be deemed to represent to the Company each time it delivers a Notice of Conversion that such Notice of Conversion
has not violated the restrictions set forth in this paragraph 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 stated in the most recent of the following: (A) the Company’s most recent periodic or annual report
filed with the Commission, as the case may be; (B) a more recent public announcement by the Company; or (C) a more recent written
notice by the Company or the Transfer Agent setting forth the number of shares of Common Stock outstanding. Upon the written or
oral request of a Holder, the Company shall within two Trading Days confirm orally and in writing to the Holder the number of
shares of Common Stock then outstanding. In any case, the number of outstanding shares of Common Stock shall be determined after
giving effect to the conversion or exercise of securities of the Company, including this Warrant, by the Holder or its Affiliates
since the date as of which such number of outstanding shares of Common Stock was reported. The “Beneficial Ownership
Limitation” shall be 4.99% of the number of shares of the Common Stock outstanding immediately after giving effect to
the issuance of shares of Common Stock issuable upon exercise of this Warrant held by the Holder. The Holder, upon not less than
61 days’ prior 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 such increase or decrease will not be effective until
the 61st day after such notice is delivered to the Company. The Beneficial Ownership Limitation 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 contained herein 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.


 






    	 	4	 



     


    

 


f)
Company Warrant Call. The Company shall have the right, subject to satisfaction of the conditions in this Section 2(f),
to cause the exercise of this Warrant (“Forced Exercise”). The Company shall deliver prior written notice to
the Holder at least ten (10) business days (“Forced Exercise Notice”) prior to the effective date (the “Forced
Exercise Effective Date”) of such Forced Exercise. In order to effectuate a Forced Exercise, the following conditions
shall be satisfied as of the Forced Exercise Effective Date: (i) there is an effective registration statement permitting the issuance
of the Warrant Shares to or resale of the Warrant Shares by the Holder; (ii) the Company shall have satisfied and be current all
of its filing requirements under the Securities and Exchange Act of 1934; (iii) the VWAP of the Common Stock shall equal or exceed
300% of the Purchase Price of the Securities for either 10 consecutive trading days, or 15 of 25 consecutive trading days immediately
preceding the date of the Forced Exercise Notice; (iv) the Warrant Shares may be delivered to the Holder via DWAC; and (v) all
of the Warrants issued pursuant to the Purchase Agreement are called by the Company for a Forced Exercise. The Holder shall have
the option to exercise this Warrant, on a Cashless Exercise basis pursuant to Section 2(c) above, during such ten (10) day notice
period.


 


Section
3. Certain Adjustments.


 


a)
Stock Dividends and Stock Splits. If the Company, at any time while this Warrant is outstanding: (i) pays a stock dividend
or otherwise makes a distribution or distributions payable in shares of Common Stock on shares of Common Stock or any Common Stock
Equivalents (which, for avoidance of doubt, shall not include any shares of Common Stock issued by the Company upon the exercise
of any options or warrants, including the Warrants); (ii) subdivides outstanding shares of Common Stock into a larger number of
shares; (iii) combines (including by way of a reverse stock split) outstanding shares of Common Stock into a smaller number of
shares; or (iv) issues, in the event of a reclassification of shares of the Common Stock, any shares of capital stock of the Company,
then the Exercise Price shall be multiplied by a fraction of which the numerator shall be the number of shares of Common Stock
(excluding any treasury shares of the Company) 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)
Subsequent Equity Sales. If, at any time while this Warrant is outstanding, the Company or any Subsidiary, as applicable,
sells or grants any option to purchase, or grants any right to reprice, or otherwise dispose of or issues, any Common Stock or
Common Stock Equivalents entitling any Person to acquire shares of Common Stock at an effective price per share that is lower
than the then Exercise Price, other than in connection with any Exempt Issuance ( as defined below) (such lower price, the “Base
Share Price” and such issuances collectively, a “Dilutive Issuance”) (if the holder of the Common Stock or Common
Stock Equivalents so issued shall at any time, whether by operation of purchase price adjustments, reset provisions, floating
conversion, exercise or exchange prices or otherwise, or due to warrants, options or rights per share which are issued in connection
with such issuance, be entitled to receive shares of Common Stock at an effective price per share that is lower than the Exercise
Price, such issuance shall be deemed to have occurred for less than the Exercise Price on such date of the Dilutive Issuance),
then the Exercise Price shall be reduced to equal the price that is the same percentage increase over the Base Share Price as
the exercise price of the warrants in this Offering is over the Base Share Price. Such adjustment shall be made whenever such
Common Stock or Common Stock Equivalents are issued. Notwithstanding the foregoing, no adjustment will be made under this Section
3(b) in respect of an Exempt Issuance. If the Company enters into a Variable Rate Transaction, despite the prohibition thereon
in the Purchase Agreement, the Company shall be deemed to have issued Common Stock or Common Stock Equivalents at the lowest possible
conversion or exercise price at which such securities may be converted or exercised. The Company shall notify the Holder in writing,
no later than the Trading Day following the issuance of any Common Stock or Common Stock Equivalents subject to this Section 3(b),
indicating therein the applicable issuance price, or applicable reset price, exchange price, conversion price and other pricing
terms (such notice, the “Dilutive Issuance Notice”). For purposes of clarification, whether or not the Company provides
a Dilutive Issuance Notice pursuant to this Section 3(b), upon the occurrence of any Dilutive Issuance, the Holder is entitled
to receive a number of Warrant Shares based upon the Base Share Price on or after the date of such Dilutive Issuance, regardless
of whether the Holder accurately refers to the Base Share Price in the Notice of Exercise. Notwithstanding this Section 3(b),
nothing contained herein shall cause the number of warrant shares to increase. Any adjustment herein shall solely be with respect
to the Exercise Price. Further, notwithstanding the foregoing, this Section 3(b) shall be of no further force and effect upon
the Company listing its Common Stock on a national securities exchange (NYSE, NYSE American or Nasdaq).


 






    	 	5	 



     


    

 


c) Subsequent
Rights Offerings. If the Company, at any time while the Warrant is outstanding, shall issue rights, options or warrants to
all holders of Common Stock (and not to the Holder) entitling them to subscribe for or purchase shares of Common Stock at a price
per share less than the VWAP on the record date mentioned below, then the Exercise Price shall be multiplied by a fraction, of
which the denominator shall be the number of shares of the Common Stock outstanding on the date of issuance of such rights, options
or warrants plus the number of additional shares of Common Stock offered for subscription or purchase, and of which the numerator
shall be the number of shares of the Common Stock outstanding on the date of issuance of such rights, options or
warrants plus the number of shares which the aggregate offering price of the total number of shares so offered (assuming receipt
by the Company in full of all consideration payable upon exercise of such rights, options or warrants) would purchase at such
VWAP. Such adjustment shall be made whenever such rights, options or warrants are issued, and shall become effective immediately
after the record date for the determination of stockholders entitled to receive such rights, options or warrants.


 


d) Pro
Rata Distributions. If the Company, at any time while this Warrant is outstanding, shall distribute to all holders of Common
Stock (and not to the Holder) evidences of its indebtedness or assets (including cash and cash dividends) or rights or warrants
to subscribe for or purchase any security other than the Common Stock (which shall be subject to Section 3(b)), then in each such
case the Exercise Price shall be adjusted by multiplying the Exercise Price in effect immediately prior to the record date fixed
for determination of stockholders entitled to receive such distribution by a fraction of which the denominator shall be the VWAP
determined as of the record date mentioned above, and of which the numerator shall be such VWAP on such record date less the then
per share fair market value at such record date of the portion of such assets or evidence of indebtedness or rights or warrants
so distributed applicable to one outstanding share of the Common Stock as determined by the Board of Directors in good faith.
In either case the adjustments shall be described in a statement provided to the Holder of the portion of assets or evidences
of indebtedness so distributed or such subscription rights applicable to one share of Common Stock. Such adjustment shall
be made whenever any such distribution is made and shall become effective immediately after the record date mentioned above.


 


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 more than 50% 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 (without regard to any
limitation in Section 2(e) or Section 2(f) on the exercise of this Warrant), the number of shares of Common Stock of the successor
or acquiring corporation or of the Company, if it is the surviving corporation, and any additional consideration (the “Alternate
Consideration”) receivable as a result of such Fundamental Transaction by a holder of the number of shares of Common
Stock for which this Warrant is exercisable immediately prior to such Fundamental Transaction (without regard to any limitation
in Section 2(e) or Section 2(f) on the exercise of this Warrant). For purposes of any such exercise, the determination of the
Exercise Price shall be appropriately adjusted to apply to such Alternate Consideration based on the amount of Alternate Consideration
issuable in respect of one (1) share of Common Stock in such Fundamental Transaction, and the Company shall apportion the Exercise
Price among the Alternate Consideration in a reasonable manner reflecting the relative value of any different components of the
Alternate Consideration. If holders of Common Stock are given any choice as to the securities, cash or property to be received
in a Fundamental Transaction, then the Holder shall be given the same choice as to the Alternate Consideration it receives upon
any exercise of this Warrant following such Fundamental Transaction. The Company shall cause any successor entity in a Fundamental
Transaction in which the Company is not the survivor (the “Successor Entity”) to assume in writing all of the
obligations of the Company under this Warrant and the other Transaction Documents in accordance with the provisions of this Section
3(e) pursuant to written agreements in form and substance reasonably satisfactory to the holders of a majority of the Warrants
prior to such Fundamental Transaction and shall, at the option of the Holder, deliver to the Holder in exchange for this Warrant
a security of the Successor Entity evidenced by a written instrument substantially similar in form and substance to this Warrant
which is exercisable for a corresponding number of shares of capital stock of such Successor Entity (or its parent entity) equivalent
to the shares of Common Stock acquirable and receivable upon exercise of this Warrant (without regard to any limitations on the
exercise of this Warrant) prior to such Fundamental Transaction, and with an exercise price which applies the exercise price hereunder
to such shares of capital stock (but taking into account the relative value of the shares of Common Stock pursuant to such Fundamental
Transaction and the value of such shares of capital stock, such number of shares of capital stock and such exercise price being
for the purpose of protecting the economic value of this Warrant immediately prior to the consummation of such Fundamental Transaction),
and which is reasonably satisfactory in form and substance to the Holder. Upon the occurrence of any such Fundamental Transaction,
the Successor Entity shall succeed to, and be substituted for (so that from and after the date of such Fundamental Transaction,
the provisions of this Warrant and the other Transaction Documents referring to the “Company” shall refer instead
to the Successor Entity), and may exercise every right and power of the Company and shall assume all of the obligations of the
Company under this Warrant and the other Transaction Documents with the same effect as if such Successor Entity had been named
as the Company herein.

f) Calculations.
All calculations under this Section 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 any treasury shares of the Company) 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 each Holder a notice setting
                                         forth the Exercise Price after such adjustment and any resulting adjustment to the number
                                         of Warrant Shares and setting forth a brief statement of the facts requiring such adjustment.



 


		ii.	Notice
                                         to Allow Exercise by Holder. If (A) the Company shall declare a dividend (or any
                                         other distribution in whatever form) on the Common Stock, (B) the Company shall declare
                                         a special nonrecurring cash dividend on or a redemption of the Common Stock, (C) the
                                         Company shall authorize the granting to all holders of the Common Stock of rights or

                                         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

                                         delivered to the Holder at its last address as it shall appear upon the Warrant Register
                                         of the Company, at least ten (10) 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,

                                         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 hereunder 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.

 (h) For purposes of this Warrant, the term “Exempt Issuance” shall mean the issuance of (a) shares of Common Stock or options or other stock based awards to employees, officers or directors and consultants of the Company pursuant to the Company’s stock or option plans existing as of the date hereof, to employees, officers or directors and consultants of the Company pursuant to a written agreement, provided that such shares of Common Stock are not registered and carry no registration rights other than on Form S-8, (b) securities upon the exercise or exchange of or conversion of any Securities issued hereunder and/or other securities exercisable or exchangeable for or convertible into shares of Common Stock issued and outstanding on the original Issue Date of this Warrant, provided that such securities have not been amended since the date of this Agreement to increase the number of such securities or to decrease the exercise price, exchange price or conversion price of such securities, and (c) securities issued pursuant to acquisitions or strategic transactions approved by a majority of the disinterested directors of the Company, provided that any such issuance shall only be to a Person (or to the equity holders of a Person) which is, itself or through its subsidiaries, an operating company or an owner of an asset in a business synergistic with the business of the Company and shall provide to the Company additional benefits in addition to the investment of funds, but shall not include a transaction in which the Company is issuing securities primarily for the purpose of raising capital or to an entity whose primary business is investing in securities. Exempt Issuance shall not include any transaction with one or more persons or entities whereby such other persons or entities will own more than the 50% of the outstanding shares of Common Stock following such transaction.




 


Section
4. Transfer of Warrant.


 


a) Transferability.
Subject to compliance with any applicable securities laws and the conditions set forth in Section 4(d) hereof and to the provisions
of Section 4.1 of the Purchase Agreement, 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 the Holder delivers an assignment form to the Company assigning this Warrant 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.


 






    	 	8	 



     


    

 


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


 


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


 


d) Transfer
Restrictions; Registration Rights. At the time of the surrender of this Warrant in connection with any transfer of this Warrant,
the transfer of this Warrant shall be either: (i) registered pursuant to an effective registration statement under the Securities
Act and under applicable state securities or blue sky laws or exempt therefrom; or (ii) eligible for resale without holding period,
volume or manner-of-sale restrictions or current public information requirements pursuant to Rule 144. The Holder and any permitted
transfer shall be entitled to the registration rights with respect to the resale of the Warrant Shares as described under the
Purchase Agreement.


 


e) Representation
by the Holder. The Holder, by the acceptance hereof, represents and warrants that it is acquiring this Warrant and, upon any
exercise hereof, will acquire the Warrant Shares issuable upon such exercise, for its own account and not with a view to or for
distributing or reselling such Warrant Shares or any part thereof in violation of the Securities Act or any applicable state securities
law, except pursuant to sales registered or exempted under the Securities Act.


 


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.


 


(i) The
Company covenants that until such time as the Warrant is no longer 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).


 






    	 	9	 



     


    

 


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


 


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


 


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


 


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


 


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


 


h) Notices.
Any notice, request or other document required or permitted to be given or delivered to the Holder by the Company shall be
delivered in accordance with the notice provisions of the Purchase Agreement.


 


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


 






    	 	10	 



     


    

 


l) Amendment.
This Warrant may be modified or amended or the provisions hereof waived with the written consent of the Company and the Holder.


 


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.


 


o) 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 conflict of laws thereof. Each party agrees that all legal proceedings concerning the interpretation, enforcement and defense
of the transactions contemplated by any of the Transaction Documents (whether brought against a party hereto or its respective
Affiliates, directors, officers, shareholders, employees or agents) shall be commenced in the state and federal courts sitting
in the City of New York, Borough of Manhattan (the “New York Courts”). The Holder and the Company each hereby
irrevocably submits to the exclusive jurisdiction of the New York Courts for the adjudication of any dispute hereunder or in connection
herewith or with any transaction contemplated hereby or discussed herein (including with respect to the enforcement of any of
the Transaction Documents), 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 such New York Courts, or such New York Courts are improper or inconvenient
venue for such proceeding. The Holder and the Company each 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 applicable law. The Holder and the Company each
hereby irrevocably waives, to the fullest extent permitted by applicable law, any and all right to trial by jury in any legal
proceeding arising out of or relating to this Warrant or the transactions contemplated hereby. If any party shall commence an
action or proceeding to enforce any provisions of this Warrant, then the prevailing party in such action or proceeding shall be
reimbursed by the other party for its attorneys’ fees and other costs and expenses incurred in the investigation, preparation
and prosecution of such action or proceeding.
