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 PDF copy submitted
by e-mail (or e-mail attachment) of the Notice of Exercise in the form annexed hereto (the “Notice of Exercise”).
Within the earlier of (i) two (2) Trading Days and (ii) the number of Trading Days comprising the Standard Settlement
Period (as defined in Section 2(d)(i) herein) following the date of exercise as aforesaid, the Holder shall deliver the aggregate
Exercise Price for the 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 as soon as reasonably
practicable 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.


 






    3


     


    

 


b)            Exercise
Price. The aggregate exercise price of this Warrant, except for a nominal exercise price of $0.0001 per Warrant Share, was pre-funded
to the Company on or prior to the Initial Exercise Date and, consequently, no additional consideration (other than the nominal exercise
price of $0.0001 per Warrant Share) shall be required to be paid by the Holder to any Person to effect any exercise of this Warrant.
The Holder shall not be entitled to the return or refund of all, or any portion, of such pre-paid aggregate exercise price under any
circumstance or for any reason whatsoever, including in the event this Warrant shall not have been exercised prior to the Termination
Date. The remaining unpaid exercise price per share of Common Stock under this Warrant shall be $0.0001, subject to adjustment hereunder
(the “Exercise Price”).


 


c)            Cashless
Exercise. 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) 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


 






    4


     


    

 


(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).


 


		d)	Mechanics of Exercise.



 


 i.              Delivery of Warrant Shares Upon Exercise. The Company shall cause the Warrant Shares purchased hereunder to be transmitted by the Transfer Agent to the Holder by crediting the account of the Holder’s or its designee’s balance account with The Depository Trust Company through its Deposit or Withdrawal at Custodian system (“DWAC”) if the Company is then a participant in such system and either (A) there is an effective registration statement permitting the issuance of the Warrant Shares to or resale of the Warrant Shares by the Holder or (B) this Warrant is being exercised via cashless exercise, and otherwise by physical delivery of a certificate, registered in the Company’s share register in the name of the Holder or its designee, for the number of Warrant Shares to which the Holder is entitled pursuant to such exercise to the address specified by the Holder in the Notice of Exercise by 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 (increasing to $20 per Trading Day on the third Trading Day after the Warrant Share Delivery Date) for each Trading Day after such Warrant Share Delivery Date until such Warrant Shares are delivered or Holder rescinds such exercise. The Company agrees to maintain a transfer agent that is a participant in the FAST program so long as this Warrant remains outstanding and exercisable. As used herein, “Standard Settlement Period” means the standard settlement period, expressed in a number of Trading Days, on the Company’s primary Trading Market with respect to the Common Stock as in effect on the date of delivery of the Notice of Exercise. Notwithstanding the foregoing, with respect to any Notice(s) of Exercise delivered on or prior to 12:00 p.m. (New York City time) on the Initial Exercise Date, which may be delivered at any time after the time of execution of the Purchase Agreement, the Company agrees to deliver the Warrant Shares subject to such notice(s) by 4:00 p.m. (New York City time) on the Initial Exercise Date and the Initial Exercise Date shall be the Warrant Share Delivery Date for purposes hereunder, provided that payment of the aggregate Exercise Price (other than in the case of a cashless exercise) is received by such Warrant Share Delivery Date.




 






    5


     


    

 


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


 


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


 


iv.            Compensation
for Buy-In on Failure to Timely Deliver Warrant Shares Upon Exercise. In addition to any other rights available to the Holder, if
the Company fails to cause the Transfer Agent to transmit to the Holder the Warrant Shares 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. The obligation of the Company to pay compensation
for Buy-In under this Section 2(d)(iv) is subject to delivery by the Holder of the aggregate Exercise Price in accordance with
the terms of Section 2(a).


 






    6


     


    

 


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


 


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


 






    7


     


    

 


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
and shall have no liability for exercises of this Warrant that are not in compliance with the Beneficial Ownership Limitation (other
than to the extent that information on the number of outstanding shares of Common Stock of the Company is provided by the Company and
relied upon by the Holder). 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 and the Company shall have
no obligation to verify or confirm the accuracy of such determination and shall have no liability for exercises of this Warrant that
are not in compliance with the Beneficial Ownership Limitation. 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%/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 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.


 






    9


     


    

 


b)            Subsequent
Rights Offerings. In addition to any adjustments pursuant to Section 3(a) above, if at any time the Company grants, issues
or sells any 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, that, 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, that, 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).


 






    10


     


    

 


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 or any Subsidiary,
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 or 50% or more of the voting power of the common equity of the Company, (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, merger or scheme of arrangement)
with another Person or group of Persons whereby such other Person or group acquires 50% or more of the outstanding shares of Common Stock
or 50% or more of the voting power of the common equity of the Company (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 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 Section 3(d) pursuant
to written agreements in form and substance reasonably satisfactory to the Holder and approved by the Holder (without unreasonable delay)
prior to such Fundamental Transaction and shall, at the option of the Holder, deliver to the Holder in exchange for this Warrant a security
of the Successor Entity evidenced by a written instrument substantially similar in form and substance to this Warrant which is exercisable
for a corresponding number of shares of capital stock of such Successor Entity (or its parent entity) equivalent to the shares of Common
Stock acquirable and receivable upon exercise of this Warrant (without regard to any limitations on the exercise of this Warrant) prior
to such Fundamental Transaction, and with an exercise price which applies the exercise price hereunder to such shares of capital stock
(but taking into account the relative value of the shares of Common Stock pursuant to such Fundamental Transaction and the value of such
shares of capital stock, such number of shares of capital stock and such exercise price being for the purpose of protecting the economic
value of this Warrant immediately prior to the consummation of such Fundamental Transaction), and which is reasonably satisfactory in
form and substance to the Holder. Upon the occurrence of any such Fundamental Transaction, the Successor Entity shall succeed to, and
be substituted for (so that from and after the date of such Fundamental Transaction, the provisions of this Warrant and the other Transaction
Documents referring to the “Company” shall refer instead to the Successor Entity), and may exercise every right and power
of the Company and shall assume all of the obligations of the Company under this Warrant and the other Transaction Documents with the
same effect as if such Successor Entity had been named as the Company herein.

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 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.


 






    12


     


    

 


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 (or any of its Subsidiaries) is a party,
any sale or transfer of all or substantially all of its assets, 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 email to the Holder at its
last 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, 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.


 






    14


     


    

 


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


 


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


 


Section 5.             Miscellaneous.


 


a)            No
Rights as Stockholder Until Exercise; No Settlement in Cash. This Warrant does not entitle the Holder to any voting rights, dividends
or other rights as a stockholder of the Company prior to the exercise hereof as set forth in Section 2(d)(i), except as expressly
set forth in Section 3. Without limiting any rights of a Holder to receive Warrant Shares on a “cashless exercise” pursuant
to Section 2(c) or to receive cash payments pursuant to Section 2(d)(i) and Section 2(d)(iv) herein, in
no event shall the Company be required to net cash settle an exercise of this Warrant.


 


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.


 






    15


     


    

 


d)            Authorized
Shares.


 


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


 


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


 


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


 






    16


     


    

 


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.


 


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 e-mail, or sent by a nationally recognized overnight courier service,
addressed to the Company, at 50 Health Sciences Drive, Stony Brook, New York 11790, Attention: James Hayward, email address: james.hayward@adnas.com,
or such other email address or address as the Company may specify for such purposes by notice to the Holders. Any and all notices or
other communications or deliveries to be provided by the Company hereunder shall be in writing and delivered personally, by e-mail, or
sent by a nationally recognized overnight courier service addressed to each Holder at the 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 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 e-mail at the e-mail address set forth in this Section on a day that is not a Trading
Day or later than 5:30 p.m. (New York City time) on any Trading Day, (iii) the second Trading Day following the date of mailing,
if sent by U.S. nationally recognized overnight courier service, or (iv) upon actual receipt by the party to whom such notice is
required to be given. To the extent that any notice provided hereunder constitutes, or contains, material, non-public information regarding
the Company or any Subsidiaries, the Company shall simultaneously file such notice with the Commission pursuant to a Current Report on
Form 8-K.


 






    17


     


    

 


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.
