    	 	3	 



     


    

 


hereto
(the “Notice of Exercise”). Within the earlier of (i) two (2) Trading Days and (ii) the number of Trading Days
comprising the Standard Settlement Period (as defined in Section 2(d)(i) herein) following the date of exercise as aforesaid,
the Holder shall deliver the aggregate Exercise Price for the 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 be required. Notwithstanding anything herein
to the contrary, the Holder shall not be required to physically surrender this Warrant to the Company until the Holder has purchased
all of the Warrant Shares available hereunder and the Warrant has been exercised in full, in which case, the Holder shall surrender
this Warrant to the Company for cancellation within three (3) Trading Days of the date on which the final Notice of Exercise is
delivered to the Company. Partial exercises of this Warrant resulting in purchases of a portion of the total number of Warrant
Shares available hereunder shall have the effect of lowering the outstanding number of Warrant Shares purchasable hereunder in
an amount equal to the applicable number of Warrant Shares purchased. The Holder and the Company shall maintain records showing
the number of Warrant Shares purchased and the date of such purchases. The Company shall deliver any objection to any Notice of
Exercise within one (1) Business Day of receipt of such notice. The Holder and any assignee, by acceptance of this Warrant,
acknowledge and agree that, by reason of the provisions of this paragraph, following the purchase of a portion of the Warrant
Shares hereunder, the number of Warrant Shares available for purchase hereunder at any given time may be less than the amount
stated on the face hereof.


 


Notwithstanding
the foregoing in this Section 2(a), a holder whose interest in this Warrant is a beneficial interest in certificate(s) representing
this Warrant held in book-entry form through DTC (or another established clearing corporation performing similar functions), shall
effect exercises made pursuant to this Section 2(a) by delivering to DTC (or such other clearing corporation, as applicable) the
appropriate instruction form for exercise, complying with the procedures to effect exercise that are required by DTC (or such other
clearing corporation, as applicable), subject to a Holder’s right to elect to receive a Warrant in certificated form pursuant
to the terms of the Warrant Agency Agreement, in which case this sentence shall not apply.


 


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


 


c)       Cashless
Exercise. If at the time of exercise hereof there is no effective registration statement registering, or the prospectus contained
therein is not available for the issuance of the Warrant Shares to the Holder, then this Warrant may also be exercised, in whole
or in part, at such time by means of a “cashless exercise” in which the Holder shall be entitled to receive a number
of Warrant Shares equal to the quotient obtained by dividing [(A-B) (X)] by (A), where:


 






    	 	4	 



     


    

 


(A) =  as applicable:
(i) the VWAP on the Trading Day immediately preceding the date of the applicable Notice of Exercise if such Notice of Exercise
is (1) both executed and delivered pursuant to Section 2(a) hereof on a day that is not a Trading Day or (2) both executed and
delivered pursuant to Section 2(a) hereof on a Trading Day prior to the opening of “regular trading hours” (as defined
in Rule 600(b)(68) of Regulation NMS promulgated under the federal securities laws) on such Trading Day, (ii) at the option of
the Holder, either (y) the VWAP on the Trading Day immediately preceding the date of the applicable Notice of Exercise or (z) the
Bid Price of the Common Stock on the principal Trading Market as reported by Bloomberg L.P. as of the time of the Holder’s
execution of the applicable Notice of Exercise if such Notice of Exercise is executed during “regular trading hours”
on a Trading Day and is delivered within two (2) hours thereafter (including until two (2) hours after the close of “regular
trading hours” on a Trading Day) pursuant to Section 2(a) hereof or (iii) the VWAP on the date of the applicable Notice of
Exercise if the date of such Notice of Exercise is a Trading Day and such Notice of Exercise is both executed and delivered pursuant
to Section 2(a) hereof after the close of “regular trading hours” on such Trading Day;


 


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


 


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


 


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


 


Notwithstanding
anything herein to the contrary, on the Termination Date, this Warrant shall be automatically exercised via cashless exercise
pursuant to this Section 2(c). Other than cash payments pursuant to Section 2(d)(i) and 2(d)(iv) herein and the right of a Holder
to receive Warrant Shares upon a cashless exercise pursuant to this Section 2(c) herein, under no circumstances shall the Company
be obligated to provide the Holder with a net cash settlement payment. 


 


d)       Mechanics
of Exercise.


 


		i.	Delivery of Warrant Shares Upon
Exercise. The Company shall cause the Warrant Shares purchased hereunder to be transmitted by the Transfer Agent to the Holder
by crediting the account of the Holder’s or its designee’s balance account with The Depository Trust Company through
its Deposit or Withdrawal at Custodian system (“DWAC”) if the Company is then a participant in such system
and either (A) there is an effective registration statement permitting the issuance of the Warrant Shares to or resale of the
Warrant Shares by Holder or (B) this Warrant is being



  






    	 	5	 



     


    

 





		  	exercised via cashless exercise,
and otherwise by physical delivery of a certificate, registered in the Company’s share register in the name of the Holder
or its designee, for the number of Warrant Shares to which the Holder is entitled pursuant to such exercise to the address specified
by the Holder in the Notice of Exercise by the date that is the earliest of (i) two (2) Trading Days after the delivery to the
Company of the Notice of Exercise, (ii) one (1) Trading Day after delivery of the aggregate Exercise Price to the Company and
(iii) the number of Trading Days comprising the Standard Settlement Period after the delivery to the Company of the Notice of
Exercise (such date, the “Warrant Share Delivery Date”). Upon delivery of the Notice of Exercise, the Holder
shall be deemed for all corporate purposes to have become the holder of record of the Warrant Shares with respect to which this
Warrant has been exercised, irrespective of the date of delivery of the Warrant Shares, provided that payment of the aggregate
Exercise Price (other than in the case of a cashless exercise) is received within the earlier of (i) two (2) Trading Days and
(ii) the number of Trading Days comprising the Standard Settlement Period following delivery of the Notice of Exercise. If the
Company fails for any reason to deliver to the Holder the Warrant Shares subject to a Notice of Exercise by the Warrant Share
Delivery Date, the Company shall pay to the Holder, in cash, as liquidated damages and not as a penalty, for each $1,000 of Warrant
Shares subject to such exercise (based on the VWAP of the Common Stock on the date of the applicable Notice of Exercise), $10
per Trading Day for each Trading Day after such Warrant Share Delivery Date until such Warrant Shares are delivered or Holder
rescinds such exercise. The Company agrees to maintain a transfer agent that is a participant in the FAST program so long as this
Warrant remains outstanding and exercisable. As used herein, “Standard Settlement Period” means the standard
settlement period, expressed in a number of Trading Days, on the Company’s primary Trading Market with respect to the Common
Stock as in effect on the date of delivery of the Notice of Exercise.



 


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.


 






    	 	6	 



     


    

 


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


 


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


 






    	 	7	 



     


    

 


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


 


vii.       Closing
of Books. The Company will not close its stockholder books or records in any manner which prevents the timely exercise of this
Warrant, pursuant to the terms hereof.


 


e)       Holder’s
Exercise Limitations. The Company shall not effect any exercise of this Warrant, and a Holder shall not have the right to
exercise any portion of this Warrant, pursuant to Section 2 or otherwise, to the extent that after giving effect to such issuance
after exercise as set forth on the applicable Notice of Exercise, the Holder (together with the Holder’s Affiliates, and
any other Persons acting as a group together with the Holder or any of the Holder’s Affiliates (such Persons, “Attribution
Parties”)), would beneficially own in excess of the Beneficial Ownership Limitation (as defined below).  For purposes
of the foregoing sentence, the number of shares of Common Stock beneficially owned by the Holder and its Affiliates and Attribution
Parties shall include the number of shares of Common Stock issuable upon exercise of this Warrant with respect to which such determination
is being made, but shall exclude the number of shares of Common Stock which would be issuable upon (i) exercise of the remaining,
nonexercised portion of this Warrant beneficially owned by the Holder or any of its Affiliates or Attribution Parties and (ii)
exercise or conversion of the unexercised or nonconverted portion of any other securities of the Company (including, without limitation,
any other Common Stock Equivalents) subject to a limitation on conversion or exercise analogous to the limitation contained herein
beneficially owned by the Holder or any of its Affiliates or Attribution Parties.  Except as set forth in the preceding sentence,
for purposes of this Section 2(e), beneficial ownership shall be calculated in accordance with Section 13(d) of the Exchange Act
and the rules and regulations promulgated thereunder, it being acknowledged by the Holder that the Company is not representing
to the Holder that such calculation is in compliance with Section 13(d) of the Exchange Act and the Holder is solely responsible
for any schedules required to be filed in accordance therewith. To the extent that the limitation contained in this Section 2(e)
applies, the determination of whether this Warrant is exercisable (in relation to other securities owned by the Holder together
with any Affiliates and Attribution Parties) and of which portion of this Warrant is exercisable shall be in the sole discretion
of the Holder, and the submission of a Notice of Exercise shall be deemed to be the Holder’s determination of whether this
Warrant is exercisable (in relation to other securities owned









    	 	8	 



     


    

 


by
the Holder together with any Affiliates and Attribution Parties) and of which portion of this Warrant is exercisable, in each
case subject to the Beneficial Ownership Limitation. To ensure compliance with the this restriction, each Holder shall be deemed
to represent to the Company each time it delivers a Notice of Exercise that such Notice of Exercise has not violated the restrictions
set forth in his Section 2.(e),, and the Company shall have no obligation to verify or confirm the accuracy of such determination.
In addition, a determination as to any group status as contemplated above shall be determined in accordance with Section 13(d)
of the Exchange Act and the rules and regulations promulgated thereunder. For purposes of this Section 2(e), in determining the
number of outstanding shares of Common Stock, a Holder may rely on the number of outstanding shares of Common Stock as reflected
in (A) the Company’s most recent periodic or annual report filed with the Commission, as the case may be, (B) a more recent
public announcement by the Company or (C) a more recent written notice by the Company or the Transfer Agent setting forth the
number of shares of Common Stock outstanding.  Upon the written or oral request of a Holder, the Company shall within one
Trading 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 or its Affiliates or Attribution Parties since the date as of which such
number of outstanding shares of Common Stock was reported. The “Beneficial Ownership Limitation” shall be 4.99%
(or, upon election by a Holder prior to the issuance of any Warrants, 9.99%) of the number of shares of the Common Stock outstanding
immediately after giving effect to the issuance of shares of Common Stock issuable upon exercise of this Warrant. The Holder,
upon notice to the Company, may increase or decrease the Beneficial Ownership Limitation provisions of this Section 2(e), provided
that the Beneficial Ownership Limitation in no event exceeds 9.99% of the number of shares of the Common Stock outstanding immediately
after giving effect to the issuance of shares of Common Stock upon exercise of this Warrant held by the Holder and the provisions
of this Section 2(e) shall continue to apply. Any increase in the Beneficial Ownership Limitation will not be effective until
the 61st day after such notice is delivered to the Company. The provisions of this paragraph shall be construed and
implemented in a manner otherwise than in strict conformity with the terms of this Section 2(e) to correct this paragraph (or
any portion hereof) which may be defective or inconsistent with the intended Beneficial Ownership Limitation herein contained
or to make changes or supplements necessary or desirable to properly give effect to such limitation. The limitations contained
in this paragraph shall apply to a successor holder of this Warrant.


 


Section 3.         Certain
Adjustments.


 


a)       Stock
Dividends and Splits. If the Company, at any time while this Warrant is outstanding: (i) pays a stock dividend or otherwise
makes a distribution or distributions on shares of its Common Stock or any other equity or equity equivalent securities payable
in shares of Common Stock (which, for avoidance of doubt, shall not include any shares of Common Stock issued by the Company upon
exercise of this Warrant), (ii) subdivides outstanding shares of 


 


 






    	 	9	 



     


    

 


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
Rights Offerings. In addition to any adjustments pursuant to Section 3(a) above, if at any time the Company grants, issues
or sells any Common Stock Equivalents or rights to purchase stock, warrants, securities or other property pro rata to the record
holders of any class of shares of Common Stock (the “Purchase Rights”), then the Holder will be entitled to
acquire, upon the terms applicable to such Purchase Rights, the aggregate Purchase Rights which the Holder could have acquired
if the Holder had held the number of shares of Common Stock acquirable upon complete exercise of this Warrant (without regard to
any limitations on exercise hereof, including without limitation, the Beneficial Ownership Limitation) immediately before the date
on which a record is taken for the grant, issuance or sale of such Purchase Rights, or, if no such record is taken, the date as
of which the record holders of shares of Common Stock are to be determined for the grant, issue or sale of such Purchase Rights
(provided, however, to the extent that the Holder’s right to participate in any such Purchase Right would result in the Holder
exceeding the Beneficial Ownership Limitation, then the Holder shall not be entitled to participate in such Purchase Right to such
extent (or beneficial ownership of such shares of Common Stock as a result of such Purchase Right to such extent) and such Purchase
Right to such extent shall be held in abeyance for the Holder until such time, if ever, as its right thereto would not result in
the Holder exceeding the Beneficial Ownership Limitation).


 


c)       Pro
Rata Distributions. During such time as this Warrant is outstanding, if the Company shall declare or make any dividend or other
distribution of its assets (or rights to acquire its assets) to holders of shares of Common Stock, by way of return of capital
or otherwise (including, without limitation, any distribution of cash, stock or other securities, property or options by way of
a dividend, spin off, reclassification, corporate rearrangement, scheme of arrangement or other similar transaction) (a "Distribution"),
at any time after the issuance of this Warrant, then, in each such case, the Holder shall be entitled to participate in such Distribution
to the same extent that the Holder would have participated therein if the Holder had held the number of shares of Common Stock
acquirable upon complete exercise of this Warrant (without regard to any limitations on exercise hereof, including without limitation,
the Beneficial Ownership Limitation) immediately before the date of which a record is taken for such Distribution, or, if no such
record is taken, the date as of which the record holders of shares of Common Stock are to be determined for the participation in
such Distribution (provided, however, to the 


 






    	 	10	 



     


    

 


extent
that the Holder's right to participate in any such Distribution would result in the Holder exceeding the Beneficial Ownership
Limitation, then the Holder shall not be entitled to participate in such Distribution to such extent (or in the beneficial ownership
of any shares of Common Stock as a result of such Distribution to such extent) and the portion of such Distribution shall be held
in abeyance for the benefit of the Holder until such time, if ever, as its right thereto would not result in the Holder exceeding
the Beneficial Ownership Limitation). To the extent that this Warrant has not been partially or completely exercised at the time
of such Distribution, such portion of the Distribution shall be held in abeyance for the benefit of the Holder until the Holder
has exercised this Warrant.


 


d)       Fundamental
Transaction. If, at any time while this Warrant is outstanding, (i) the Company, directly or indirectly, in one or more related
transactions effects any merger or consolidation of the Company with or into another Person, (ii) the Company, directly or indirectly,
effects any sale, lease, license, assignment, transfer, conveyance or other disposition of all or substantially all of its assets
in one or a series of related transactions, (iii) any, direct or indirect, purchase offer, tender offer or exchange offer (whether
by the Company or another Person) is completed pursuant to which holders of Common Stock are permitted to sell, tender or exchange
their shares for other securities, cash or property and has been accepted by the holders of 50% or more of the outstanding Common
Stock, (iv) the Company, directly or indirectly, in one or more related transactions effects any reclassification, reorganization
or recapitalization of the Common Stock or any compulsory share exchange pursuant to which the Common Stock is effectively converted
into or exchanged for other securities, cash or property, or (v) the Company, directly or indirectly, in one or more related transactions
consummates a stock or share purchase agreement or other business combination (including, without limitation, a reorganization,
recapitalization, spin-off or scheme of arrangement) with another Person or group of Persons whereby such other Person or group
acquires more than 50% of the outstanding shares of Common Stock (not including any shares of Common Stock held by the other Person
or other Persons making or party to, or associated or affiliated with the other Persons making or party to, such stock or share
purchase agreement or other business combination) (each a “Fundamental Transaction”), then, upon any subsequent
exercise of this Warrant, the Holder shall have the right to receive, for each Warrant Share that would have been issuable upon
such exercise immediately prior to the occurrence of such Fundamental Transaction, at the option of the Holder (without regard
to any limitation in Section 2(e) on the exercise of this Warrant), 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) on the exercise
of this Warrant). For purposes of any such exercise, the determination of the Exercise Price shall be appropriately adjusted to
apply to such Alternate Consideration based on the amount of Alternate Consideration issuable in respect of one share of Common
Stock in such Fundamental Transaction, and the Company shall apportion the Exercise Price among the Alternate Consideration in
a reasonable manner reflecting the relative value of any different components of the Alternate Consideration. If holders of Common
Stock 


 






    	 	11	 



     


    

  


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 other than one in which a Successor Entity
(as defined below) that is a publicly traded corporation whose common stock is quoted or listed on a Trading Market assumes this
Warrant such that the Warrant shall be exercisable for the publicly traded common stock of such Successor Entity, the Company
or any Successor Entity shall, at the Holder’s option, exercisable at any time concurrently with, or within 30 days after,
the consummation of the Fundamental Transaction (or, if later, the date of the public announcement of the applicable Fundamental
Transaction), purchase this Warrant from the Holder by paying to the Holder 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; provided,
however, if the Fundamental Transaction is not within the Company's control, including not approved by the Company's Board
of Directors, Holder shall only be entitled to receive from the Company or any Successor Entity, as of the date of consummation
of such Fundamental Transaction, the same type or form of consideration (and in the same proportion), at the Black Scholes Value
(as defined below) of the unexercised portion of this Warrant, that is being offered and paid to the holders of Common Stock of
the Company in connection with the Fundamental Transaction, whether that consideration be in the form of cash, stock or any combination
thereof, or whether the holders of Common Stock are given the choice to receive from among alternative forms of consideration
in connection with the 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 Termination Date, (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 greater of
(i) 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 (ii) the greater of (x) the last VWAP immediately prior to the public announcement
of such Fundamental Transaction and (y) the last VWAP immediately prior to the consummation of 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 Termination Date. The payment of the Black Scholes Value will be made by wire transfer of immediately available funds
within five Business Days of the Holder’s election (or, if later, on the effective date 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 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


 






    	 	12	 



     


    

 


 


the Holder (without
unreasonable delay) prior to such Fundamental Transaction and shall, at the option of the Holder, deliver to the Holder in exchange
for this Warrant a security of the Successor Entity evidenced by a written instrument substantially similar in form and substance
to this Warrant which is exercisable for a corresponding number of shares of capital stock of such Successor Entity (or its parent
entity) equivalent to the 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 referring to the “Company” shall refer instead
to the Successor Entity), and may exercise every right and power of the Company and shall assume all of the obligations of the
Company under this Warrant with the same effect as if such Successor Entity had been named as the Company herein. For the avoidance
of doubt, if, at any time while this Warrant is outstanding, a Fundamental Transaction occurs, pursuant to the terms of this Section
3(d), the Holder shall not be entitled to receive more than one of (i) the 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, (ii) an amount of cash (or other type or form of consideration as provided in this Section 3(d)) equal
to the Black Scholes Value of the remaining unexercised portion of this Warrant as calculated pursuant this Section 3(d), or (iii)
the assumption by the Successor Entity of all of the obligations of the Company under this Warrant and the option to receive a
security of the Successor Entity evidenced by a written instrument substantially similar in form and substance to this Warrant.








 


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


 


f)       Notice
to Holder.


 


i.       Adjustment
to Exercise Price. Whenever the Exercise Price is adjusted pursuant to any provision of this Section 3, the Company shall promptly
deliver to the Holder by facsimile or email a notice setting forth the Exercise Price after such adjustment and any resulting adjustment
to the number of Warrant Shares and setting forth a brief statement of the facts requiring such adjustment.










    	 	13	 



     


    

 






ii.       Notice
to Allow Exercise by Holder. If (A) the Company shall declare a dividend (or any other distribution in whatever form) on the
Common Stock, (B) the Company shall declare a special nonrecurring cash dividend on or a redemption of the Common Stock, (C) the
Company shall authorize the granting to all holders of the Common Stock rights or warrants to subscribe for or purchase any shares
of capital stock of any class or of any rights, (D) the approval of any stockholders of the Company shall be required in connection
with any reclassification of the Common Stock, any consolidation or merger to which the Company is a party, any sale or transfer
of all or substantially all of the assets of the Company, or any compulsory share exchange whereby the Common Stock is converted
into other securities, cash or property, or (E) the Company shall authorize the voluntary or involuntary dissolution, liquidation
or winding up of the affairs of the Company, then, in each case, the Company shall cause to be delivered by facsimile or email
to the Holder at its last facsimile number or email address as it shall appear upon the Warrant Register of the Company, at least
20 calendar days prior to the applicable record or effective date hereinafter specified, a notice stating (x) the date on which
a record is to be taken for the purpose of such dividend, distribution, redemption, rights or warrants, or if a record is not to
be taken, the date as of which the holders of the Common Stock of record to be entitled to such dividend, distributions, redemption,
rights or warrants are to be determined or (y) the date on which such reclassification, consolidation, merger, sale, transfer or
share exchange is expected to become effective or close, and the date as of which it is expected that holders of the Common Stock
of record shall be entitled to exchange their shares of the Common Stock for securities, cash or other property deliverable upon
such reclassification, consolidation, merger, sale, transfer or share exchange; provided that the failure to deliver such notice
or any defect therein or in the delivery thereof shall not affect the validity of the corporate action required to be specified
in such notice. To the extent that any notice provided in this Warrant constitutes, or contains, material, non-public information
regarding the Company or any of the Subsidiaries, the Company shall simultaneously file such notice with the Commission pursuant
to a Current Report on Form 8-K. The Holder shall remain entitled to exercise this Warrant during the period commencing on the
date of such notice to the effective date of the event triggering such notice except as may otherwise be expressly set forth herein.


 


Section 4.         Transfer
of Warrant.


 


a)       Transferability.
This Warrant and all rights hereunder (including, without limitation, any registration rights) are transferable, in whole or in
part, upon surrender of this Warrant at the principal office of the Company or its designated agent, together with a written assignment
of this Warrant substantially in the form attached hereto duly executed by the Holder or its agent or attorney and funds sufficient
to pay any transfer taxes payable upon the making of such transfer. Upon such surrender and, if required,


 









    	 	14	 



     


    

  


such
payment, the Company shall execute and deliver a new Warrant or Warrants in the name of the assignee or assignees, as applicable,
and in the denomination or denominations specified in such instrument of assignment, and shall issue to the assignor a new Warrant
evidencing the portion of this Warrant not so assigned, and this Warrant shall promptly be cancelled. Notwithstanding anything
herein to the contrary, the Holder shall not be required to physically surrender this Warrant to the Company unless the Holder
has assigned this Warrant in full, in which case, the Holder shall surrender this Warrant to the Company within three (3) Trading
Days of the date on which the Holder delivers an assignment form to the Company assigning this Warrant in full. The Warrant, if
properly assigned in accordance herewith, may be exercised by a new holder for the purchase of Warrant Shares without having a
new Warrant issued.


 


b)       New
Warrants. If this Warrant is not held in global form through DTC (or any successor depositary), 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 Warrant Agent shall register this Warrant, upon records to be maintained by the Warrant Agent for that purpose
(the “Warrant Register”), in the name of the record Holder hereof from time to time. The Company and the Warrant
Agent may deem and treat the registered Holder of this Warrant, or, if the Warrant is held in book-entry form, the beneficial owner
of this Warrant, as the absolute owner hereof for the purpose of any exercise hereof or any distribution to the Holder, and for
all other purposes, absent actual notice to the contrary.


 


Section 5.         Miscellaneous.


 


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


 


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









    	 	15	 



     


    

 



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


 


d)       Authorized
Shares.


 


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


 


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.









    	 	16	 



     


    

 



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


 


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


 


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









    	 	17	 



     


    

 



h)       Notices.
Any and all notices or other communications or deliveries to be provided by the Holders hereunder including, without limitation,
any Notice of Exercise, shall be in writing and delivered personally, by facsimile or e-mail, or sent by a nationally recognized
overnight courier service, addressed to the Company, at 100 Campus Drive, Florham Park, New Jersey 07932, Attention: Dov Elefant

as the Company may specify for such purposes by notice to the Holders. Any and all notices or other communications or deliveries
to be provided by the Company hereunder shall be in writing and delivered personally, by facsimile or e-mail, or sent by a nationally
recognized overnight courier service addressed to each Holder at the facsimile number, e-mail address or address of such Holder
appearing on the books of the Company. Any notice or other communication or deliveries hereunder shall be deemed given and effective
on the earliest of (i) the time of transmission, if such notice or communication is delivered via facsimile at the facsimile number
or via e-mail at the e-mail address set forth in this Section prior to 5:30 p.m. (New York City time) on any date, (ii) the next
Trading Day after the time of transmission, if such notice or communication is delivered via facsimile at the facsimile number
or via e-mail at the e-mail address set forth in this Section on a day that is not a Trading Day or later than 5:30 p.m. (New York
City time) on any Trading Day, (iii) the second Trading Day following the date of mailing, if sent by U.S. nationally recognized
overnight courier service, or (iv) upon actual receipt by the party to whom such notice is required to be given. To the extent
that any notice provided hereunder constitutes, or contains, material, non-public information regarding the Company or any subsidiaries,
the Company shall promptly file such notice with the Commission pursuant to a Current Report on Form 8-K or other method permitted
by Regulation FD promulgated under the Exchange Act.


 


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.





 



    	 	18	 



     


    




 



l)       Amendment.
In addition to amendments permitted by the Warrant Agency Agreement, this Warrant may be modified or amended or the provisions
hereof waived with the written consent of the Company, on the one hand, and the Holder or the beneficial owner of this Warrant,
on the other hand.


 


m)       Severability.
Wherever possible, each provision of this Warrant shall be interpreted in such manner as to be effective and valid under applicable
law, but if any provision of this Warrant shall be prohibited by or invalid under applicable law, such provision shall be ineffective
to the extent of such prohibition or invalidity, without invalidating the remainder of such provisions or the remaining provisions
of this Warrant.


 


n)       Headings.
The headings used in this Warrant are for the convenience of reference only and shall not, for any purpose, be deemed a part of
this Warrant.


 


o)       Warrant
Agency Agreement. If this Warrant is held in global form through DTC (or any successor depositary), this Warrant is issued
subject to the Warrant Agency Agreement. To the extent any provision of this Warrant conflicts with the express provisions of the
Warrant Agency Agreement, the provisions of this Warrant shall govern and be controlling.
