	Warrant Shares:                	 	 	
        Initial Exercise Date: January [ ],
        2021

        Issue Date: January [ ], 2021 



 


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 [ ], 2021 (the “Initial Exercise Date”) and on or prior to 5:00 p.m.
(New York City time) on January [ ], 2026 (the “Termination Date”) but not thereafter, to subscribe for and
purchase from Synaptogenix, 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).


 


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 21, 2021, among the Company and the purchasers signatory thereto.


 


Section 2.    Exercise.


 


a)    Exercise
of Warrant. Exercise of the purchase rights represented by this Warrant may be made, in whole or in part, at any time or times
on or after the Initial Exercise Date and on or before the Termination Date by delivery to the Company of a duly executed facsimile
copy or PDF copy submitted by e-mail (or e-mail attachment) of the Notice of Exercise in the form annexed hereto
(the “Notice of Exercise”). On the earlier of (i) the second Trading Day and (ii) the last Trading
Day of the applicable Standard Settlement Period (as defined in Section 2(d)(i) herein) following the date said Notice of
Exercise is delivered to the Company, the Holder shall deliver payment of the aggregate Exercise Price of the shares thereby purchased
pursuant to the applicable Notice of Exercise by wire transfer or cashier’s check drawn on a United States bank or, if available,
pursuant to the cashless exercise procedure specified in Section 2(c) below if 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 five (5) 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 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 Common Stock under this Warrant shall be $1.725, subject to adjustment hereunder
(the “Exercise Price”).


 


c)    Cashless
Exercise. If at any time after the six-month anniversary of the Closing Date, there is no effective Registration Statement
registering, or no current prospectus available for, the resale of the Warrant Shares by the Holder, then this Warrant may 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:


  


(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. (“Bloomberg”)
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 to the Company 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, 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 characteristics of the Warrants being exercised. The Company agrees
not to take any position contrary to this Section 2(c). For avoidance of doubt, except as set forth in Section 2(d)(iv), the
Company shall not be required to pay cash if it cannot deliver registered Warrant Shares upon settlement.


 


“Bid
Price” means, for any date, the price determined by the first of the following clauses that applies: (a) if the
Common Stock is then listed or quoted on a Trading Market, the bid price of the Common Stock for the time in question (or the nearest
preceding date) on the Trading Market on which the Common Stock is then listed or quoted as reported by Bloomberg (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 foregoing does not apply, the bid price
of the Common Stock in the over-the-counter market on the electronic bulletin board for such Common Stock as reported by Bloomberg
as of such time of determination, (c) if no bid price is reported for the Common Stock by Bloomberg as of such time of determination,
the average of the bid prices of all of the market makers for the Common Stock as reported on the Pink Open Market (the “Pink
Sheets”) as of such time of determination, 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 Purchasers 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.


 






     


     


    

 


“VWAP”
means, for any date, the price determined by the first of the following clauses that applies: (a) if the Common Stock is then
listed or quoted on a Trading Market, the daily volume weighted average price of the Common Stock for such date (or the nearest
preceding date) on the Trading Market on which the Common Stock is then listed or quoted as reported by Bloomberg (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 foregoing does not apply, the bid price
of the Common Stock in the over-the-counter market on the electronic bulletin board for such Common Stock as reported by Bloomberg
as of such time of determination, (c) if no bid price is reported for the Common Stock by Bloomberg as of such time of determination,
the average of the bid prices of all of the market makers for the Common Stock as reported in the Pink Sheets as of such time of
determination, 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 Purchasers 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, if the conditions of a cashless exercise are otherwise met, this Warrant
shall be automatically exercised via cashless exercise pursuant to this Section 2(c).


 


d)    Mechanics
of Exercise.


 


i.    Delivery
of Warrant Shares Upon Exercise. The Company shall cause the Warrant Shares purchased hereunder to be transmitted by the Transfer
Agent to the Holder by crediting the account of the Holder’s or its designee’s balance account with The Depository
Trust Company through its Deposit or Withdrawal at Custodian system (“DWAC”) if the Company is then a participant
in such system and either (A) there is an effective registration statement permitting the issuance of the Warrant Shares to
or resale of the Warrant Shares by Holder or (B) this Warrant is being exercised via cashless exercise, and otherwise by physical
delivery of a certificate, registered in the Company’s share register in the name of the Holder or its designee, for the
number of Warrant Shares to which the Holder is entitled pursuant to such exercise to the address specified by the Holder in the
Notice of Exercise by the date that is the 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 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 (increasing to $20 per Trading Day on the fifth Trading Day after
such liquidated damages begin to accrue) for each Trading Day after such Warrant Share Delivery Date until such Warrant Shares
are delivered or Holder rescinds such exercise. The Company agrees to maintain a transfer agent that is a participant in the FAST
program so long as this Warrant remains outstanding and exercisable. As used herein, “Standard Settlement Period”
means the standard settlement period, expressed in a number of Trading Days, on the Company’s primary Trading Market with
respect to the Common Stock as in effect on the date of delivery of the Notice of Exercise.


 






     


     


    

 


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 by delivering written notice to
the Company at any time prior to the Company delivering such Warrant Shares.


 


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


 


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


 






     


     


    

 


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


 


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


 


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


 


To
the extent that the limitation contained in this Section 2(e) applies, the determination of whether this Warrant is exercisable
(in relation to other securities owned by the Holder together with any Affiliates and Attribution Parties) and of which portion
of this Warrant is exercisable shall be in the sole discretion of the Holder, and the submission of a Notice of Exercise shall
be deemed to be the Holder’s determination of whether this Warrant is exercisable (in relation to other securities owned
by the Holder together with any Affiliates and Attribution Parties) and of which portion of this Warrant is exercisable, in each
case subject to the Beneficial Ownership Limitation, and the Company shall have no obligation to verify or confirm the accuracy
of such determination. In addition, a determination as to any group status as contemplated above shall be determined in accordance
with Section 13(d) of the Exchange Act and the rules and regulations promulgated thereunder, 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.


 






     


     


    

 


For
purposes of this Section 2(e), in determining the number of outstanding shares of Common Stock, a Holder may rely on the number
of outstanding shares of Common Stock as reflected in (A) the Company’s most recent periodic or annual report filed
with the Commission, as the case may be, (B) a more recent public announcement by the Company or (C) a more recent written
notice by the Company or the Transfer Agent setting forth the number of shares of Common Stock outstanding. Upon the written
or oral request of a Holder, the Company shall within two Trading Days confirm orally and in writing to the Holder the number of
shares of Common Stock then outstanding. In any case, the number of outstanding shares of Common Stock shall be determined
after giving effect to the conversion or exercise of securities of the Company, including this Warrant, by the Holder or its Affiliates
or Attribution Parties since the date as of which such number of outstanding shares of Common Stock was reported. The “Beneficial
Ownership Limitation” shall be [4.99/9.99]% 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.


 


f)    [Reserved]. 


 


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
Rights Offerings. In addition to any adjustments pursuant to Section 3(a) above, if at any time while this Warrant
is outstanding the Company grants, issues or sells any Common Stock Equivalents or rights to purchase stock, warrants, securities
or other property pro rata to all record holders 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 all holders of shares of Common Stock, by way of return
of capital or otherwise (including, without limitation, any distribution of cash, stock or other securities (other than as contemplated
by Section 3(a) above), 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 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).


 


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, exclusive lease, exclusive 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, or (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, if the Company is not the surviving entity in the
Fundamental Transaction or the Common Stock is converted into the right to receive the Alternate Consideration only in the Fundamental
Transaction, the Holder shall have the right to receive, in lieu of each Warrant Share that would have been issuable upon such
exercise immediately prior to the occurrence of such Fundamental Transaction (without regard to any limitation in Section 2(e)
on the exercise of this Warrant), the same securities and/or other property as would have been paid for a Warrant Share as if such
Warrant Share were outstanding on and as of the closing of such Fundamental Transaction (without regard to any limitation in Section 2(e)
on the exercise of this Warrant) (the “Alternate Consideration”). For purposes of any such exercise, the determination
of the Exercise Price shall be appropriately adjusted to apply to such Alternate Consideration based on the amount of Alternate
Consideration issuable in respect of one share of Common Stock in such Fundamental Transaction, and the Company shall apportion
the Exercise Price among the Alternate Consideration in a reasonable manner reflecting the relative value of any different components
of the Alternate Consideration. If holders of Common Stock are given any choice as to the securities, cash or property to be received
in a Fundamental Transaction, then the Holder shall be given the same choice as to the Alternate Consideration it receives upon
any exercise of this Warrant following such Fundamental Transaction. The Company shall cause any successor entity in a Fundamental
Transaction in which the Company is not the survivor (the “Successor Entity”) to assume in writing all of the
obligations of the Company under this Warrant in accordance with the provisions of this Warrant and to covenant to, at the option
of the Holder, deliver to the Holder in exchange for this Warrant a warrant of the Successor Entity evidenced by a written instrument
substantially similar in form and substance to this Warrant which is exercisable for the Alternate Consideration (without regard
to any limitations on the exercise of this Warrant), and with an exercise price which applies the exercise price hereunder to such
Alternate Consideration consistent with this Section 3(d). 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 and the other Transaction Documents
with the same effect as if such Successor Entity had been named as the Company herein.


 






     


     


    

 


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


 


f)    Notice
to Holder.


 


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


 


ii.    Notice
to Allow Exercise by Holder. If (A) the Company shall declare a dividend (or any other distribution in whatever form)
on the Common Stock, (B) the Company shall declare a special nonrecurring cash dividend on or a redemption of the Common Stock,
(C) the Company shall authorize the granting to all holders of the Common Stock rights or warrants to subscribe for or purchase
any shares of capital stock of any class or of any rights, (D) the approval of any stockholders of the Company shall be required
in connection with any reclassification of the Common Stock, any consolidation or merger to which the Company is a party, any sale
or transfer of all or substantially all of the assets of the Company, or any compulsory share exchange whereby the Common Stock
is converted into other securities, cash or property, or (E) the Company shall authorize the voluntary or involuntary dissolution,
liquidation or winding up of the affairs of the Company, then, in each case, the Company shall cause to be delivered by facsimile
or email to the Holder at its last facsimile number or email address as it shall appear upon the Warrant Register of the Company,
at least 10 calendar days prior to the applicable record or effective date hereinafter specified, a notice stating (x) the
date on which a record is to be taken for the purpose of such dividend, distribution, redemption, rights or warrants, or if a record
is not to be taken, the date as of which the holders of the Common Stock of record to be entitled to such dividend, distributions,
redemption, rights or warrants are to be determined or (y) the date on which such reclassification, consolidation, merger,
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 contemporaneously 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.


 






     


     


    

 


g)    Voluntary
Adjustment By Company. The Company may at any time during the term of this Warrant reduce the then current Exercise Price to
any amount and for any period of time deemed appropriate by the Board of Directors of the Company; provided, however, that the
Company agrees not to adjust the Exercise Price in any way that would violate the listing rules of the Nasdaq Stock Market.


 


Section 4.    Transfer
of Warrant.


 


a)    Transferability.
This Warrant and all rights hereunder (including, without limitation, any registration rights) are transferable, in whole or in
part, upon surrender of this Warrant at the principal office of the Company or its designated agent, together with a written assignment
of this Warrant substantially in the form attached hereto duly executed by the Holder or its agent or attorney and funds sufficient
to pay any transfer taxes payable upon the making of such transfer. Upon such surrender and, if required, such payment, the Company
shall execute and deliver a new Warrant or Warrants in the name of the assignee or assignees, as applicable, and in the denomination
or denominations specified in such instrument of assignment, and shall issue to the assignor a new Warrant evidencing the portion
of this Warrant not so assigned, and this Warrant shall promptly be cancelled. Notwithstanding anything herein to the contrary,
the Holder shall not be required to physically surrender this Warrant to the Company unless the Holder has assigned this Warrant
in full, in which case, the Holder shall surrender this Warrant to the Company within three (3) Trading Days of the date the
Holder delivers an assignment form to the Company assigning this Warrant in full. The Warrant, if properly assigned in accordance
herewith, may be exercised by a new holder for the purchase of Warrant Shares without having a new Warrant issued.


 


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


 


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


 


d)
Transfer Restrictions. 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), except as expressly set forth
in Section 3.


 


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


 


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


 


d)    Authorized
Shares.


 


The
Company covenants that, during the period the Warrant is outstanding, it will reserve from its authorized and unissued Common Stock
a sufficient number of shares to provide for the issuance of the Warrant Shares upon the exercise of any purchase rights under
this Warrant. The Company further covenants that its issuance of this Warrant shall constitute full authority to its officers who
are charged with the duty of 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.


 


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


 


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


 


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