COMMON STOCK PURCHASE WARRANT


 


SENESCo
TECHNOLOGIES, INC.


 


	Warrant Shares: [_______]	Initial Issuance Date: January __, 2014


 


THIS
COMMON STOCK PURCHASE WARRANT (the “Warrant”) certifies that, for value received, _____________ or its
assigns (the “Holder”) is entitled, upon the terms and subject to the limitations on exercise and the
conditions hereinafter set forth, at any time on or after January __, 2013 (the “Initial Exercise Date”)
and on or prior to the close of business on the five year anniversary of the Initial Issuance Date (the “Termination
Date”) but not thereafter, to subscribe for and purchase from Senesco Technologies, Inc., a Delaware corporation
(the “Company”), up to ______ 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). This Warrant is one of a series of warrants issued by the Company in connection
with a public offering of Common Stock and of like tenor, except as to the number of shares of Common Stock subject thereto
(collectively, the “Company Warrants”).


 


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 January 4, 2013, among the Company and the purchasers
signatory thereto.


 



    	1



    	 



    

 


Section 2.          Exercise.


 


a)        Exercise
of the purchase rights represented by this Warrant may be made, in whole or in part, at any time or times on or after the Initial
Exercise Date and on or before the Termination Date by delivery to the Company (or such other office or agency of the Company
as it may designate by notice in writing to the registered Holder at the address of the Holder appearing on the books of the Company)
of a duly executed facsimile copy of the Notice of Exercise Form annexed hereto. Within three (3) Trading Days following the date
of exercise as aforesaid, the Holder shall deliver the aggregate Exercise Price for the shares specified in the applicable Notice
of Exercise by wire transfer or cashier’s check drawn on a United States bank unless the cashless exercise procedure specified
in Section 2(c) below is specified in the applicable Notice of Exercise. No ink-original Notice of Exercise shall be required,
nor shall any medallion guarantee (or other type of guarantee or notarization) of any Notice of Exercise form be required.
Notwithstanding anything herein to the contrary, the Holder shall not be required to physically surrender this Warrant
to the Company until the Holder has purchased all of the Warrant Shares available hereunder and the Warrant has been exercised
in full, in which case, the Holder shall surrender this Warrant to the Company for cancellation within three (3) Trading Days
of the date 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 one (1) Business Day of receipt of such notice. The Holder
and any assignee, by acceptance of this Warrant, acknowledge and agree that, by reason of the provisions of this paragraph, following
the purchase of a portion of the Warrant Shares hereunder, the number of Warrant Shares available for purchase hereunder at any
given time may be less than the amount stated on the face hereof.


 


b)         Exercise
Price. The exercise price per share of the Common Stock under this Warrant shall be $0.12, subject to adjustment hereunder
(the “Exercise Price”).


 


c)         Cashless
Exercise. So long as permitted under applicable securities laws, this Warrant may 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) * (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.



 



    	2



    	 



    

 


“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
on a national securities exchange, 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 the Common Stock is then quoted on the OTC Bulletin
Board or an OTC Markets Group Inc. market, the volume weighted average price of the Common Stock for such date (or the nearest
preceding date), (c) if the Common Stock is not then listed or quoted for trading on any of the above and if prices for the Common
Stock are then reported in the “Pink Sheets” (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 Securities then outstanding and reasonably acceptable to the Company, the fees and expenses of which shall be paid by the
Company.


 


Notwithstanding
anything herein to the contrary, on the Termination Date, this Warrant shall be automatically exercised pursuant to this Section
2.


 


d)      
    Mechanics of Exercise.


 


i.            Delivery
of Warrant Shares Upon Exercise. The Company shall use best efforts to cause the Warrant Shares purchased hereunder to 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 either (A) there is an effective registration statement permitting the issuance of the Warrant Shares to or resale of
the Warrant Shares by Holder, (B) this Warrant is being exercised via cashless exercise or (C) the shares are eligible for resale
by the Holder without volume or manner-of-sale limitations pursuant to Rule 144, and otherwise 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, (B) surrender of this Warrant (if required) and (C) payment of the aggregate Exercise
Price as set forth above (including by cashless exercise, if permitted) (such date, the “Warrant Share Delivery Date”).
The Warrant Shares shall be deemed to have been issued, and Holder or any other person so designated to be named therein shall
be deemed to have become a holder of record of such shares for all purposes, as of the date the Warrant has been exercised, with
payment to the Company of the Exercise Price (or by cashless exercise, if permitted) and all taxes required to be paid by the Holder,
if any, pursuant to Section 2(d)(vi) prior to the issuance of such shares, having been paid. 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.


 



    	3



    	 



    

 


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


 


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


 


iv.         Compensation
for Buy-In on Failure to Timely Deliver Warrant Shares Upon Exercise. In addition to any other rights available to the Holder,
if the Company fails to cause the Transfer Agent to transmit to the Holder the Warrant Shares 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. Notwithstanding the foregoing,
if the Company is not permitted to issue unregistered shares to the Holder via cashless exercise because such issuance is prohibited
under applicable securities laws, the parties acknowledge that the Company shall not have any cash liability associated therewith.


 



    	4



    	 



    

 


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 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.


 


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.


 


		i.	Notwithstanding anything to the contrary set forth in this Warrant, at no time may all or a portion
of the Warrant be exercised if the number of shares of Common Stock to be issued pursuant to such exercise would exceed,
when aggregated with all other shares of Common Stock owned by the Holder at such time, the number of shares of Common Stock which
would result in the Holder beneficially owning (as determined in accordance with Section 13(d) of the Exchange Act and the rules
thereunder) more than 4.99% of all of the Common Stock outstanding at such time (the “4.99% Beneficial Ownership Limitation”);
provided, however, that upon the Holder providing the Company with sixty-one (61) days’ advance notice (the
“4.99% Waiver Notice”) that the Holder would like to waive this Section2(e)(i) with regard to any or all shares
of Common Stock issuable upon exercise of this Warrant, this Section 2(e)(i) will be of no force or effect with regard to all or
a portion of this Warrant referenced in the 4.99% Waiver Notice.



 



    	5



    	 



    

 


		ii.	Notwithstanding anything to the contrary set forth in this Warrant, at no time may all or a portion
of this Warrant be exercised if the number of shares of Common Stock to be issued pursuant to such exercise, when aggregated with
all other shares of Common Stock owned by the Holder at such time, would result in the Holder beneficially owning (as determined
in accordance with Section 13(d) of the Exchange Act and the rules thereunder) in excess of 9.99% of the then issued and outstanding
shares of Common Stock outstanding at such time (the “9.99% Beneficial Ownership Limitation” and the lower of
the 9.99% Beneficial Ownership Limitation and the 4.99% Beneficial Ownership Limitation then in effect, the “Maximum Percentage”).



 


		iii.	By written notice to the Company, the Holder may from time to time decrease the Maximum Percentage
to any other percentage specified in such notice.



 


		iv.	For purposes of this Warrant, in determining the number of outstanding shares of Common Stock,
the Holder may rely on the number of outstanding shares of Common Stock as reflected in (1) the Company’s most recent Form
10-K, Form 10-Q, Current Report on Form 8-K or other public filing with the Securities and Exchange Commission, as the case may
be, (2) a more recent public announcement by the Company or (3) any other notice by the Company setting forth the number of shares
of Common Stock outstanding. 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 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 its affiliates since the date as of which such number of outstanding
shares of Common Stock was reported, which in any event are convertible or exercisable, as the case may be, into shares of the
Company’s Common Stock within 60 days’ of such calculation and which are not subject to a limitation on conversion
or exercise analogous to the limitation contained herein. The provisions of this paragraph shall be
construed and implemented in a manner otherwise than in strict conformity with the terms of this Section 2(e) to correct this paragraph
(or any portion hereof) which may be defective or inconsistent with the intended beneficial ownership limitation herein contained
or to make changes or supplements necessary or desirable to properly give effect to such limitation.



 



    	6



    	 



    

 


Section 3.          Certain
Adjustments.


 


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


 


b)         Subsequent
Equity Sales. Until the eighteen month anniversary of the Initial Issuance Date, if the Company or any Subsidiary thereof,
as applicable, shall sell or grant any option to purchase, or sell or grant any right to reprice, or otherwise dispose of or issue
(or announce any offer, sale, grant or any option to purchase or other disposition) any Common Stock or Common Stock Equivalents,
at an Offering Price (as defined below) per share less than the Exercise Price then in effect (such lower price, the “Base
Share Price” and such issuances collectively, a “Dilutive Issuance”) (it being understood and agreed
that 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 Offering
Price per share that is less 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 at such Offering Price), then simultaneously with the consummation of each Dilutive
Issuance, the Exercise Price shall be reduced and only reduced to equal the Base Share Price. For purposes of this section, “Offering
Price” shall mean: (i) for a Dilutive Issuance involving only Common Stock, the purchase price per share of such Common
Stock; (ii) for a Dilutive Issuance involving units comprised of Common Stock and warrants, the purchase price per unit; (iii)
for a Dilutive Issuance involving convertible preferred stock or convertible debt securities, the stated value of such convertible
preferred stock or convertible debt securities divided by the number of shares issuable upon conversion thereunder. Such adjustment
shall be made whenever such Common Stock or Common Stock Equivalents are issued. Notwithstanding the foregoing, no adjustments
shall be made, paid or issued under this Section 3(b) in respect of an Exempt Issuance. The Company shall notify the Holder, in
writing, no later than the Trading Day following the issuance or deemed 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 regardless of whether the
Holder accurately refers to the Base Share Price in the Notice of Exercise. 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.


 



    	7



    	 



    

 


c)         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, 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.


 



    	8



    	 



    

 


d)         Fundamental
Transaction. If, at any time while this Warrant is outstanding, the Company completes a Fundamental Transaction then, upon
any subsequent exercise of this Warrant, the Holder shall have the right to receive, for each share of Warrant Stock that would
have been issuable upon such exercise immediately prior to the occurrence of such Fundamental Transaction, at the option of the
Holder (without regard to any limitation in Section 2 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 (subject to the
limitations on exercise set forth in Section 2(e) of this Warrant). For purposes of any such exercise, the determination of the
Exercise Price shall be appropriately adjusted to apply to such Alternate Consideration based on the amount of Alternate Consideration
issuable in respect of one share of Common Stock in such Fundamental Transaction, and the Company shall apportion the Exercise
Price among the Alternate Consideration in a reasonable manner reflecting the relative value of any different components of the
Alternate Consideration. If holders of Common Stock are given any choice as to the securities, cash or property to be received
in a Fundamental Transaction, then the Holder shall be given the same choice as to the Alternate Consideration it receives upon
any exercise of this Warrant following such Fundamental Transaction. Notwithstanding anything to the contrary, in the event of
a Fundamental Transaction that is (1) a transaction where more than 50% of the consideration is payable in cash, (2) a “Rule
13e-3 transaction” as defined in Rule 13e-3 under the Exchange Act, or (3) a Fundamental Transaction involving a person or
entity not traded on a national securities exchange, the Company or any Successor Entity (as defined below) shall, at the Holder’s
option, exercisable at any time concurrently with, or within 30 days after, the consummation of the Fundamental Transaction, purchase
this Warrant from the Holder by paying to the Holder, within 5 business days, an amount of cash equal to the Black Scholes
Value of the remaining unexercised portion of this Warrant on the date of the consummation of such Fundamental Transaction. “Black
Scholes Value” means the value of this Warrant based on the Black and Scholes Option Pricing Model obtained from the
“OV” function on Bloomberg, L.P. (“Bloomberg”) determined as of the day of consummation of the applicable
Fundamental Transaction for pricing purposes and reflecting (A) a risk-free interest rate corresponding to the U.S. Treasury rate
for a period equal to the time between the date of the public announcement of the applicable Fundamental Transaction and the date
of consummation of the Fundamental Transaction, (B) an expected volatility equal to the greater of 100% and the 100 day volatility
obtained from the HVT function on Bloomberg as of the Trading Day immediately following the public announcement of the applicable
Fundamental Transaction, (C) the underlying price per share used in such calculation shall be the sum of the price per share being
offered in cash, if any, plus the value of any non-cash consideration, if any, being offered in such Fundamental Transaction and
(D) a remaining option time equal to the time between the date of the public announcement of the applicable Fundamental Transaction
and the date of consummation of the 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(d) pursuant
to written agreements in form and substance reasonably satisfactory to the Holder and approved by the Holder (without unreasonable
delay) prior to such Fundamental Transaction and shall, at the option of the holder of this Warrant, 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. For purposes hereof, (i) “Fundamental Transaction” means that (A) the
Company shall, directly or indirectly, in one or more related transactions, (i) consolidate or merge with or into (whether or not
the Company is the surviving corporation) another Person or Persons, or (ii) sell, assign, transfer, convey or otherwise dispose
of all or substantially all of the properties or assets of the Company or any of its Subsidiaries to another Person, or (iii) allow
another Person to make a purchase, tender or exchange offer that is accepted by the holders of more than 50% of the outstanding
shares of Voting Stock of the Company (not including any shares of Voting Stock of the Company held by the Person or Persons making
or party to, or associated or affiliated with the Persons making or party to, such purchase, tender or exchange offer), or (iv)
consummate a stock purchase agreement or other business combination (including, without limitation, a reorganization, recapitalization,
spin-off or scheme of arrangement) with another Person whereby such other Person acquires more than 50% of the outstanding shares
of Voting Stock of the Company (not including any shares of Voting Stock of the Company 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 purchase agreement or other
business combination, or any Person who is a holder of the Company’s securities on the date hereof or who is a Holder), or
(v) reorganize, recapitalize or reclassify its Common Stock or (B) any “person” or “group” (as these terms
are used for purposes of Sections 13(d) and 14(d) of the Securities Exchange Act of 1934, as amended (the “Exchange Act”))
is or shall become the “beneficial owner” (as defined in Rule 13d-3 under the Exchange Act), directly or indirectly,
of either (x) 50% of the aggregate ordinary voting power represented by issued and outstanding shares of Common Stock (other than
any Person who is a holder of the Company’s securities on the date hereof or who is a Holder) or (y) 50% or more of the shares
of Voting Stock of the Company not held by such Person or Persons as of the date hereof (other than any Person who is a holder
of the Company’s securities on the date hereof or who is a Holder), (ii) “Voting Stock” of a Person means
capital stock of such Person of the class or classes pursuant to which the holders thereof have the general voting power to elect,
or the general power to appoint, at least a majority of the board of directors, managers or trustees of such Person (irrespective
of whether or not at the time capital stock of any other class or classes shall have or might have voting power by reason of the
happening of any contingency), (iii) “Person” means an individual, a limited liability company, a partnership,
a joint venture, a corporation, a trust, an unincorporated organization, any other entity and a government or any department or
agency thereof and (iv) “Subsidiary” means any entity in which the Company, directly or indirectly, owns any
of the capital stock or holds an equity or similar interest.

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
mail to the Holder a notice setting forth the Exercise Price after such adjustment and any resulting adjustment to the number of
Warrant Shares and setting forth a brief statement of the facts requiring such adjustment.


 


ii.         Notice
to Allow Exercise by Holder. If (A) the Company shall declare a dividend (or any other distribution in whatever form) on the
Common Stock, (B) the Company shall declare a special nonrecurring cash dividend on or a redemption of the Common Stock, (C) the
Company shall authorize the granting to all holders of the Common Stock rights or warrants to subscribe for or purchase any shares
of capital stock of any class or of any rights, (D) the approval of any stockholders of the Company shall be required in connection
with any reclassification of the Common Stock, any consolidation or merger to which the Company is a party, any sale or transfer
of all or substantially all of the assets of the Company, or any compulsory share exchange whereby the Common Stock is converted
into other securities, cash or property, or (E) the Company shall authorize the voluntary or involuntary dissolution, liquidation
or winding up of the affairs of the Company, then, in each case, the Company shall cause to be mailed to the Holder at its last

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

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.
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 initial
issuance 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.


 



    	11



    	 



    

 


d)         Transfer
Restrictions. If, at the time of the surrender of this Warrant in connection with any transfer of this Warrant, the transfer
of this Warrant shall not be either (i) registered pursuant to an effective registration statement under the Securities Act and
under applicable state securities or blue sky laws or (ii) eligible for resale without volume or manner-of-sale restrictions or
current public information requirements pursuant to Rule 144, the Company may require, as a condition of allowing such transfer,
that the Holder or transferee of this Warrant, as the case may be, comply with the provisions of Section 5.7 of 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).


 


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.


 



    	12



    	 



    

 


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 executing stock certificates to execute and issue 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.


 


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


 


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


 



    	13



    	 



    

 


g)         Nonwaiver
and Expenses. No course of dealing or any delay or failure to exercise any right hereunder on the part of Holder shall operate
as a waiver of such right or otherwise prejudice the Holder’s rights, powers or remedies. Without limiting any other provision
of this Warrant or the Purchase Agreement, if the Company willfully and knowingly fails to comply with any provision of this Warrant,
which results in any material damages to the Holder, the Company shall pay to the Holder such amounts as shall be sufficient to
cover any costs and expenses including, but not limited to, reasonable attorneys’ fees, including those of appellate proceedings,
incurred by the Holder in collecting any amounts due pursuant hereto or in otherwise enforcing any of its rights, powers or remedies
hereunder.


 


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


 


i)         Limitation
of Liability. No provision hereof, in the absence of any affirmative action by the Holder to exercise this Warrant to purchase
Warrant Shares, and no enumeration herein of the rights or privileges of the Holder, shall give rise to any liability of the Holder
for the purchase price of any Common 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.
Any term of this Warrant may be amended or waived (either generally or in a particular instance and either retroactively or prospectively)
with the written consent of the Company and the holders of Warrants issued pursuant to the Purchase Agreement representing at
least 67% of the number of shares of Common Stock then subject to such outstanding Warrants. Notwithstanding the foregoing, the
number of Warrant Shares subject to this Warrant and the Exercise Price of this Warrant may not be amended, and the right to exercise
this Warrant may not be waived, without the written consent of the Holder (it being agreed that an amendment to or waiver under
any of the provisions of Section 3 of this Warrant shall not be considered an amendment of the number of Warrant Shares or the
Exercise Price). The Company shall give prompt written notice to the Holder of any amendment hereof or waiver hereunder that was
effected without the Holder’s written consent. No waivers of any term, condition or provision of this Warrant, in any one
or more instances, shall be deemed to be, or construed as, a further or continuing waiver of any such term, condition or provision.


 



    	14



    	 



    

 


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.
