COMMON STOCK PURCHASE WARRANT

 

Titan
Pharmaceuticals, Inc.

 

	Warrant Shares: [_______	Initial Exercise Date: February ___, 2020

 

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 February __, 2020 (the “Initial Exercise Date”) and on or prior to 5:00 p.m. (New York City time) on
February ___, 2025 (the “Termination Date”) but not thereafter, to subscribe for and purchase from Titan Pharmaceuticals,
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 August 7, 2019, 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”). Within the earlier of (i) two (2) Trading Days and (ii) the number of Trading
Days comprising the Standard Settlement Period (as defined in Section 2(d)(i) herein) following the date of exercise as aforesaid,
the Holder shall deliver the aggregate Exercise Price for the shares specified in the applicable Notice of Exercise by wire transfer
or cashier’s check drawn on a United States bank unless the cashless exercise procedure specified in Section 2(c) below is
specified in the applicable Notice of Exercise. No ink-original Notice of Exercise shall be required, nor shall any medallion guarantee
(or other type of guarantee or notarization) of any Notice of Exercise be required. Notwithstanding anything herein to the contrary,
the Holder shall not be required to physically surrender this Warrant to the Company until the Holder has purchased all of the
Warrant Shares available hereunder and the Warrant has been exercised in full, in which case, the Holder shall surrender this Warrant
to the Company for cancellation within three (3) Trading Days of the date on which the final Notice of Exercise is delivered to
the Company. Partial exercises of this Warrant resulting in purchases of a portion of the total number of Warrant Shares available
hereunder shall have the effect of lowering the outstanding number of Warrant Shares purchasable hereunder in an amount equal to
the applicable number of Warrant Shares purchased. The Holder and the Company shall maintain records showing the number of Warrant
Shares purchased and the date of such purchases. The Company shall deliver any objection to any Notice of Exercise within one (1)
Business Day of receipt of such notice. The Holder and any assignee, by acceptance of this Warrant, acknowledge and agree that,
by reason of the provisions of this paragraph, following the purchase of a portion of the Warrant Shares hereunder, the number
of Warrant Shares available for purchase hereunder at any given time may be less than the amount stated on the face hereof.

 

    1

     

    

 

b)                 
Exercise Price. The exercise price per share of Common Stock under this Warrant shall be $1.07, 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)(64) of Regulation NMS promulgated under the federal securities laws) on such Trading Day, (ii) at the option of
the Holder, either (y) the VWAP on the Trading Day immediately preceding the date of the applicable Notice of Exercise or (z) the
Bid Price of the Common Stock on the principal Trading Market as reported by Bloomberg L.P. as of the time of the Holder’s
execution of the applicable Notice of Exercise if such Notice of Exercise is executed during “regular trading hours”
on a Trading Day and is delivered within two (2) hours thereafter (including until two (2) hours after the close of “regular
trading hours” on a Trading Day) pursuant to Section 2(a) hereof or (iii) the VWAP on the date of the applicable Notice of
Exercise if the date of such Notice of Exercise is a Trading Day and such Notice of Exercise is both executed and delivered pursuant
to Section 2(a) hereof after the close of “regular trading hours” on such Trading Day;

 

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

 

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

 

    2

     

    

 

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, and the holding period
of the Warrant Shares being issued may be tacked on to the holding period of this Warrant.  The Company agrees not to
take any position contrary to this Section 2(c).

 

“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 L.P. (based on
a Trading Day from 9:30 a.m. (New York City time) to 4:02 p.m. (New York City time)), (b)  if OTCQB or OTCQX is not a Trading
Market, the volume weighted average price of the Common Stock for such date (or the nearest preceding date) on OTCQB or OTCQX as
applicable, (c) if the Common Stock is not then listed or quoted for trading on OTCQB or OTCQX and if prices for the Common Stock
are then reported in the “Pink Sheets” published by OTC Markets Group, Inc. (or a similar organization or agency succeeding
to its functions of reporting prices), the most recent bid price per share of the Common Stock so reported, or (d) in all
other cases, the fair market value of a share of Common Stock as determined by an independent appraiser selected in good faith
by the 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 L.P. (based on a Trading
Day from 9:30 a.m. (New York City time) to 4:02 p.m. (New York City time)), (b)  if OTCQB or OTCQX is not a Trading Market,
the volume weighted average price of the Common Stock for such date (or the nearest preceding date) on OTCQB or OTCQX as applicable,
(c) if the Common Stock is not then listed or quoted for trading on OTCQB or OTCQX and if prices for the Common Stock are then
reported in the “Pink Sheets” published by OTC Markets Group, Inc. (or a similar organization or agency succeeding
to its functions of reporting prices), the most recent bid price per share of the Common Stock so reported, or (d) in all
other cases, the fair market value of a share of Common Stock as determined by an independent appraiser selected in good faith
by the 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.

 

    3

     

    

 

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) the Warrant Shares are eligible for resale by the Holder without volume or manner-of-sale
limitations pursuant to Rule 144 (assuming cashless exercise of the Warrants), 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
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.

 

    4

     

    

 

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.

 

    5

     

    

 

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.

 

    6

     

    

 

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. 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% 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.

 

    7

     

    

 

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 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). To the extent that this Warrant
has not been partially or completely exercised at the time of such Distribution, such portion of the Distribution shall be held
in abeyance for the benefit of the Holder until the Holder has exercised this Warrant.

 

    8

     

    

 

d)                 
Fundamental Transaction. If, at any time while this Warrant is outstanding, (i) the Company, directly or indirectly,
in one or more related transactions effects any merger or consolidation of the Company with or into another Person, (ii) the Company,
directly or indirectly, effects any sale, lease, license, assignment, transfer, conveyance or other disposition of all or substantially
all of its assets in one or a series of related transactions, (iii) any, direct or indirect, purchase offer, tender offer or exchange
offer (whether by the Company or another Person) is completed pursuant to which holders of Common Stock are permitted to sell,
tender or exchange their shares for other securities, cash or property and has been accepted by the holders of 50% or more of the
outstanding Common Stock, (iv) the Company, directly or indirectly, in one or more related transactions effects any reclassification,
reorganization or recapitalization of the Common Stock or any compulsory share exchange pursuant to which the Common Stock is effectively
converted into or exchanged for other securities, cash or property, or (v) the Company, directly or indirectly, in one or more
related transactions consummates a stock or share purchase agreement or other business combination (including, without limitation,
a reorganization, recapitalization, spin-off, merger or scheme of arrangement) with another Person or group of Persons whereby
such other Person or group acquires more than 50% of the outstanding shares of Common Stock (not including any shares of Common
Stock held by the other Person or other Persons making or party to, or associated or affiliated with the other Persons making or
party to, such stock or share purchase agreement or other business combination) (each a “Fundamental Transaction”),
then, upon any subsequent exercise of this Warrant, the Holder shall have the right to receive, for each Warrant Share that would
have been issuable upon such exercise immediately prior to the occurrence of such Fundamental Transaction, at the option of the
Holder (without regard to any limitation in Section 2(e) on the exercise of this Warrant), the number of shares of Common Stock
of the successor or acquiring corporation or of the Company, if it is the surviving corporation, and any additional consideration
(the “Alternate Consideration”) receivable as a result of such Fundamental Transaction by a holder of the number
of shares of Common Stock for which this Warrant is exercisable immediately prior to such Fundamental Transaction (without regard
to any limitation in Section 2(e) on the exercise of this Warrant). For purposes of any such exercise, the determination of the
Exercise Price shall be appropriately adjusted to apply to such Alternate Consideration based on the amount of Alternate Consideration
issuable in respect of one share of Common Stock in such Fundamental Transaction, and the Company shall apportion the Exercise
Price among the Alternate Consideration in a reasonable manner reflecting the relative value of any different components of the
Alternate Consideration. If holders of Common Stock are given any choice as to the securities, cash or property to be received
in a Fundamental Transaction, then the Holder shall be given the same choice as to the Alternate Consideration it receives upon
any exercise of this Warrant following such Fundamental Transaction. Notwithstanding anything to the contrary, in the event of
a Fundamental Transaction, the Company or any Successor Entity (as defined below) shall, at the Holder’s option, exercisable
at any time concurrently with, or within 30 days after, the consummation of the Fundamental Transaction (or, if later, the date
of the public announcement of the applicable Fundamental Transaction), purchase this Warrant from the Holder by paying to the Holder
an amount of cash equal to the Black Scholes Value (as defined below) of the remaining unexercised portion of this Warrant on the
date of the consummation of such Fundamental Transaction. “Black Scholes Value” means the value of this Warrant
based on the Black-Scholes Option Pricing Model obtained from the “OV” function on Bloomberg, L.P. (“Bloomberg”)
determined as of the day of consummation of the applicable Fundamental Transaction for pricing purposes and reflecting (A) a risk-free
interest rate corresponding to the U.S. Treasury rate for a period equal to the time between the date of the public announcement
of the applicable Fundamental Transaction and the Termination Date, (B) an expected volatility equal to the greater of 100% and
the 100 day volatility obtained from the HVT function on Bloomberg as of the Trading Day immediately following the public announcement
of the applicable Fundamental Transaction, (C) the underlying price per share used in such calculation shall be the greater of
(i) the sum of the price per share being offered in cash, if any, plus the value of any non-cash consideration, if any, being offered
in such Fundamental Transaction and (ii) the greater of (x) the last VWAP immediately prior to the public announcement of such
Fundamental Transaction and (y) the last VWAP immediately prior to the consummation of such Fundamental Transaction and (D) a remaining
option time equal to the time between the date of the public announcement of the applicable Fundamental Transaction and the Termination
Date. The payment of the Black Scholes Value will be made by wire transfer of immediately available funds within five Business
Days of the Holder’s election (or, if later, on the effective date of the Fundamental Transaction). The Company shall cause
any successor entity in a Fundamental Transaction in which the Company is not the survivor (the “Successor Entity”)
to assume in writing all of the obligations of the Company under this Warrant and the other Transaction Documents in accordance
with the provisions of this Section 3(e) pursuant to written agreements in form and substance reasonably satisfactory to the 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.

 

    9

     

    

 

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 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. Subject to compliance with any applicable securities laws and the conditions set forth in Section
4(d) hereof and to the provisions of Section 4.1 of the Purchase Agreement, this Warrant and all rights hereunder (including,
without limitation, any registration rights) are transferable, in whole or in part, upon surrender of this Warrant at the principal
office of the Company or its designated agent, together with a written assignment of this Warrant substantially in the form attached
hereto duly executed by the Holder or its agent or attorney and funds sufficient to pay any transfer taxes payable upon the making
of such transfer. Upon such surrender and, if required, such payment, the Company shall execute and deliver a new Warrant or Warrants
in the name of the assignee or assignees, as applicable, and in the denomination or denominations specified in such instrument
of assignment, and shall issue to the assignor a new Warrant evidencing the portion of this Warrant not so assigned, and this
Warrant shall promptly be cancelled. Notwithstanding anything herein to the contrary,
the Holder shall not be required to physically surrender this Warrant to the Company unless the Holder has assigned this Warrant
in full, in which case, the Holder shall surrender this Warrant to the Company within three (3) Trading Days of the date on which
the Holder delivers an assignment form to the Company assigning this Warrant in full. The Warrant, if properly assigned
in accordance herewith, may be exercised by a new holder for the purchase of Warrant Shares without having a new Warrant issued.

 

b)                 
New Warrants. 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 Exercise 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 4.1 of the Purchase Agreement.

 

    11

     

    

 

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; 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.

 

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).

 

    12

     

    

 

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.

 

    13

     

    

 

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.

Property Rights. The Company has taken reasonable security measures to protect the secrecy, confidentiality and value of all of
their intellectual properties, except where failure to do so could not, individually or in the aggregate, reasonably be expected
to have a Material Adverse Effect.

 

(q)              
Insurance. The Company is insured by insurers of recognized financial responsibility against such losses and
risks and in such amounts as are prudent and customary in the business in which the Company is engaged, including, but not limited
to, directors and officers insurance coverage at least equal to the aggregate Subscription Amount. The Company has no reason to
believe that it will not be able to renew its existing insurance coverage as and when such coverage expires or to obtain similar
coverage from similar insurers as may be necessary to continue its business without a significant increase in cost.

 

(r)

or other arrangement providing for the furnishing of services to or by, providing for rental of real or personal property to or
from, providing for the borrowing of money from or lending of money to or otherwise requiring payments to or from any officer,
director or such employee or, to the knowledge of the Company, any entity in which any officer, director, or any such employee
has a substantial interest or is an officer, director, trustee, stockholder, member or partner, in each case in excess of $120,000
other than for (i) payment of salary or consulting fees for services rendered, (ii) reimbursement for expenses incurred on behalf
of the Company and (iii) other employee benefits, including stock option agreements under any stock option plan of the Company.

(s)               
Sarbanes-Oxley; Internal Accounting Controls. The Company is in compliance with any and all applicable requirements
of the Sarbanes-Oxley Act of 2002 that are effective as of the date hereof, and any and all applicable rules and regulations promulgated
by the Commission thereunder that are effective as of the date hereof and as of the Closing Date. Except as set forth on Schedule
3.1(s), the Company maintains a system of internal accounting controls sufficient to provide reasonable assurance that: (i)
transactions are executed in accordance with management’s general or specific authorizations, (ii) transactions are recorded
as necessary to permit preparation of financial statements in conformity with GAAP and to maintain asset accountability, (iii)
access to assets is permitted only in accordance with management’s general or specific authorization, and (iv) the recorded
accountability for assets is compared with the existing assets at reasonable intervals and appropriate action is taken with respect
to any differences. Except as set forth on Schedule 3.1(s), the Company has established disclosure controls and procedures
(as defined in Exchange Act Rules 13a-15(e) and 15d-15(e)) for the Company, and designed such disclosure controls and procedures
to ensure that information required to be disclosed by the Company in the reports it files or submits under the Exchange Act is
recorded, processed, summarized and reported, within the time periods specified in the Commission’s rules and forms. The
Company’s certifying officers have evaluated the effectiveness of the disclosure controls and procedures of the Company as
of the end of the period covered by the most recently filed periodic report under the Exchange Act (such date, the “Evaluation
Date”). The Company presented in its most recently filed periodic report under the Exchange Act the conclusions of the
certifying officers about the effectiveness of the disclosure controls and procedures based on their evaluations as of the Evaluation
Date. Since the Evaluation Date, there have been no changes in the internal control over financial reporting (as such term is defined
in the Exchange Act) of the Company that have materially affected, or is reasonably likely to materially affect, the internal control
over financial reporting of the Company.

 

(t)                
Certain Fees. Other than the compensation payable to the Placement Agent pursuant to the terms of the Placement
Agency Agreement and as set forth in the Prospectus Supplement relating to the placement of the Securities, no brokerage or finder’s
fees or commissions are or will be payable by the Company to any broker, financial advisor or consultant, finder, placement agent,
investment banker, bank or other Person with respect to the transactions contemplated by the Transaction Documents. The Purchasers
shall have no obligation with respect to any fees or with respect to any claims made by or on behalf of other Persons for fees
of a type contemplated in this Section that may be due in connection with the transactions contemplated by the Transaction Documents.

 

(u)              
Investment Company. The Company is not, and is not an Affiliate of, and immediately after receipt of payment
for the Securities, will not be or be an Affiliate of, an “investment company” within the meaning of the Investment
Company Act of 1940, as amended. The Company shall conduct its business in a manner so that it will not become an “investment
company” subject to registration under the Investment Company Act of 1940, as amended.

 

(v)              
Registration Rights. Except as provided in this Agreement and as set forth on Schedule 3.1(v), no Person
has any right to cause the Company to effect the registration under the Securities Act of any securities of the Company.

 

    16

     

    

 

(w)            
Listing and Maintenance Requirements. The Common Stock is registered pursuant to Section 12(b) or 12(g) of
the Exchange Act, and the Company has taken no action designed to, or which to its knowledge is likely to have the effect of, terminating
the registration of the Common Stock under the Exchange Act nor has the Company received any notification that the Commission is
contemplating terminating such registration. Except as set forth on Schedule 3.1(w), the Company has not in the 12 months
preceding the date hereof received notice from any Trading Market on which the Common Stock is or has been listed or quoted to
the effect that the Company is not in compliance with the listing or maintenance requirements of such Trading Market. The Company
is, and has no reason to believe that it will not in the foreseeable future continue to be, in compliance with all such listing
and maintenance requirements. The Common Stock is currently eligible for electronic transfer through the Depository Trust Company
or another established clearing corporation and the Company is current in payment of the fees to the Depository Trust Company (or
such other established clearing corporation) in connection with such electronic transfer.

 

(x)              
Application of Takeover Protections. The Company and the Board of Directors have taken all necessary action,
if any, in order to render inapplicable any control share acquisition, business combination, poison pill (including any distribution
under a rights agreement) or other similar anti-takeover provision under the Company’s certificate of incorporation (or similar
charter documents) or the laws of its state of incorporation that is or could become applicable to the Purchasers as a result of
the Purchasers and the Company fulfilling their obligations or exercising their rights under the Transaction Documents, including
without limitation as a result of the Company’s issuance of the Securities and the Purchasers’ ownership of the Securities.

 

(y)              
Disclosure. Except with respect to the material terms and conditions of the transactions contemplated by the
Transaction Documents, the Company confirms that neither it nor any other Person acting on its behalf has provided any of the Purchasers
or their agents or counsel with any information that it believes constitutes or might constitute material, non-public information
which is not otherwise disclosed in the Prospectus Supplement. The Company understands and confirms that the Purchasers will rely
on the foregoing representation in effecting transactions in securities of the Company. All of the disclosure furnished by or on
behalf of the Company to the Purchasers regarding the Company, its business and the transactions contemplated hereby, including
the Disclosure Schedules to this Agreement, is true and correct and does not contain any untrue statement of a material fact or
omit to state any material fact necessary in order to make the statements made therein, in the light of the circumstances under
which they were made, not misleading. The press releases disseminated by the Company during the 12 months preceding the date of
this Agreement taken as a whole do not contain any untrue statement of a material fact or omit to state a material fact required
to be stated therein or necessary in order to make the statements therein, in the light of the circumstances under which they were
made and when made, not misleading. The Company acknowledges and agrees that no Purchaser makes or has made any representations
or warranties with respect to the transactions contemplated hereby other than those specifically set forth in Section 3.2 hereof.

 

    17

     

    

 

(z)              
No Integrated Offering. Assuming the accuracy of the Purchasers’ representations and warranties set
forth in Section 3.2, neither the Company, nor any of its Affiliates, nor any Person acting on its or their behalf has, directly
or indirectly, made any offers or sales of any security or solicited any offers to buy any security, under circumstances that would
cause this offering of the Securities to be integrated with prior offerings by the Company for purposes of (i) the Securities Act
which would require the registration of the Purchase Warrants or the Purchase Warrant Shares under the Securities Act, or (ii)
any applicable shareholder approval provisions of any Trading Market on which any of the securities of the Company are listed or
designated.

 

(aa)           
Solvency. Based on the consolidated financial condition of the Company as of the Closing Date, after giving
effect to the receipt by the Company of the proceeds from the sale of the Securities hereunder, (i) the fair saleable value of
the Company’s assets exceeds the amount that will be required to be paid on or in respect of the Company’s existing
debts and other liabilities (including known contingent liabilities) as they mature, (ii) the Company’s assets do not constitute
unreasonably small capital to carry on its business as now conducted and as proposed to be conducted including its capital needs
taking into account the particular capital requirements of the business conducted by the Company, consolidated and projected capital
requirements and capital availability thereof, and (iii) the current cash flow of the Company, together with the proceeds the Company
would receive, were it to liquidate all of its assets, after taking into account all anticipated uses of the cash, would be sufficient
to pay all amounts on or in respect of its liabilities when such amounts are required to be paid. The Company does not intend to
incur debts beyond its ability to pay such debts as they mature (taking into account the timing and amounts of cash to be payable
on or in respect of its debt). The Company has no knowledge of any facts or circumstances which lead it to believe that it will
file for reorganization or liquidation under the bankruptcy or reorganization laws of any jurisdiction within one year from the
Closing Date. Schedule 3.1(aa) sets forth as of the date hereof all outstanding secured and unsecured Indebtedness of the
Company or for which the Company has commitments. For the purposes of this Agreement, “Indebtedness” means (x)
any liabilities for borrowed money or amounts owed in excess of $50,000 (other than trade accounts payable incurred in the ordinary
course of business), (y) all guaranties, endorsements and other contingent obligations in respect of indebtedness of others, whether
or not the same are or should be reflected in the Company’s consolidated balance sheet (or the notes thereto), except guaranties
by endorsement of negotiable instruments for deposit or collection or similar transactions in the ordinary course of business;
and (z) the present value of any lease payments in excess of $50,000 due under leases required to be capitalized in accordance
with GAAP. The Company is not in default with respect to any Indebtedness.

 

(bb)          
Tax Status. Except for matters that would not, individually or in the aggregate, have or reasonably be expected
to result in a Material Adverse Effect, the Company and its Subsidiaries each (i) has made or filed all United States federal,
state and local income and all foreign income and franchise tax returns, reports and declarations required by any jurisdiction
to which it is subject, (ii) has paid all taxes and other governmental assessments and charges that are material in amount, shown
or determined to be due on such returns, reports and declarations and (iii) has set aside on its books provision reasonably adequate
for the payment of all material taxes for periods subsequent to the periods to which such returns, reports or declarations apply.
There are no unpaid taxes in any material amount claimed to be due by the taxing authority of any jurisdiction, and the officers
of the Company know of no basis for any such claim.

(cc)

government officials or employees or to any foreign or domestic political parties or campaigns from corporate funds, (iii) failed
to disclose fully any contribution made by the Company (or made by any person acting on its behalf of which the Company is aware)
which is in violation of law, or (iv) violated in any material respect any provision of FCPA.

the fiscal year ending December 31, 2019.

Acknowledgment Regarding Purchasers’ Purchase of Securities. The Company acknowledges and agrees that
each of the Purchasers is acting solely in the capacity of an arm’s length purchaser with respect to the Transaction Documents
and the transactions contemplated thereby. The Company further acknowledges that no Purchaser is acting as a financial advisor
or fiduciary of the Company (or in any similar capacity) with respect to the Transaction Documents and the transactions contemplated
thereby and any advice given by any Purchaser or any of their respective representatives or agents in connection with the Transaction
Documents and the transactions contemplated thereby is merely incidental to the Purchasers’ purchase of the Securities. The
Company further represents to each Purchaser that the Company’s decision to enter into this Agreement and the other Transaction
Documents has been based solely on the independent evaluation of the transactions contemplated hereby by the Company and its representatives.

 

(ff)             
Acknowledgment Regarding Purchaser’s Trading Activity. Anything in this Agreement or elsewhere herein
to the contrary notwithstanding (except for Sections 3.2(f) and 4.14 hereof), it is understood and acknowledged by the Company
that: (i) none of the Purchasers has been asked by the Company to agree, nor has any Purchaser agreed, to desist from purchasing
or selling, long and/or short, securities of the Company, or “derivative” securities based on securities issued by
the Company or to hold the Securities for any specified term; (ii) past or future open market or other transactions by any Purchaser,
specifically including, without limitation, Short Sales or “derivative” transactions, before or after the closing of
this or future private placement transactions, may negatively impact the market price of the Company’s publicly-traded securities;
(iii) any Purchaser, and counter-parties in “derivative” transactions to which any such Purchaser is a party, directly
or indirectly, presently may have a “short” position in the Common Stock, and (iv) each Purchaser shall not be deemed
to have any affiliation with or control over any arm’s length counter-party in any “derivative” transaction.
The Company further understands and acknowledges that (y) one or more Purchasers may engage in hedging activities at various times
during the period that the Securities are outstanding, including, without limitation, during the periods that the value of the
Warrant Shares deliverable with respect to Securities are being determined, if applicable, and (z) such hedging activities (if
any) could reduce the value of the existing stockholders’ equity interests in the Company at and after the time that the
hedging activities are being conducted.  The Company acknowledges that such aforementioned hedging activities do not constitute
a breach of any of the Transaction Documents.

Regulation M Compliance.  The Company has not, and to its knowledge no one acting on its behalf has,

Reports were and, if still ongoing, are being conducted in material compliance with all laws and regulations applicable thereto
in the jurisdictions in which they are being conducted. The descriptions in the SEC Reports of the results of such studies are
accurate and complete in all material respects and fairly present the data derived from such studies, and the Company has no knowledge
of, or reason to believe that, any clinical study the aggregate results of which are inconsistent with or otherwise call into question
the results of any clinical study conducted by or on behalf of the Company and its Subsidiaries that are described in the SEC Reports
or the results of which are referred to in the SEC Reports. Except as disclosed in the SEC Reports, the Company has not received
any written notices or statements from the U.S. Food and Drug Administration or any other governmental agency or authority requiring,
requesting or suggesting termination, suspension or material modification for or of any clinical or preclinical studies that are
described in the SEC Reports or the results of which are referred to in the SEC Reports. Except as disclosed in the SEC Reports,

(a)              Organization; Authority. Such Purchaser is either an individual or an entity duly incorporated or formed,
validly existing and in good standing under the laws of the jurisdiction of its incorporation or formation with full right, corporate,

by the Transaction Documents and otherwise to carry out its obligations hereunder and thereunder. The execution and delivery of
the Transaction Documents and performance by such Purchaser of the transactions contemplated by the Transaction Documents have
been duly authorized by all necessary corporate, partnership, limited liability company or similar action, as applicable, on the
part of such Purchaser. Each Transaction Document to which it is a party has been duly executed by such Purchaser, and when delivered
by such Purchaser in accordance with the terms hereof, will constitute the valid and legally binding obligation of such Purchaser,
enforceable against it in accordance with its terms, except: (i) as limited by general equitable principles and applicable bankruptcy,
insolvency, reorganization, moratorium and other laws of general application affecting enforcement of creditors’ rights generally,
(ii) as limited by laws relating to the availability of specific performance, injunctive relief or other equitable remedies and
(iii) insofar as indemnification and contribution provisions may be limited by applicable law.

 

    22

     

    

 

(b)              
Understandings or Arrangements. Such Purchaser is acquiring the Securities as principal for its own account
and has no direct or indirect arrangement or understandings with any other persons to distribute or regarding the distribution
of such Securities (this representation and warranty not limiting such Purchaser’s right to sell the Securities pursuant
to the Registration Statement or otherwise in compliance with applicable federal and state securities laws). Such Purchaser is
acquiring the Securities hereunder in the ordinary course of its business. Such Purchaser understands that the Purchase Warrants
and the Purchase Warrant Shares are “restricted securities” and have not been registered under the Securities Act or
any applicable state securities law and is acquiring such Securities as principal for his, her or its own account and not with
a view to or for distributing or reselling such Securities or any part thereof in violation of the Securities Act or any applicable
state securities law, has no present intention of distributing any of such Securities in violation of the Securities Act or any
applicable state securities law and has no direct or indirect arrangement or understandings with any other persons to distribute
or regarding the distribution of such Securities in violation of the Securities Act or any applicable state securities law (this
representation and warranty not limiting such Purchaser’s right to sell such Securities pursuant to a registration statement
or otherwise in compliance with applicable federal and state securities laws).

 

(c)              Purchaser Status. At the time such Purchaser was offered the Securities, it was, and as of the date hereof
it is either: (i) an “accredited investor” as defined in Rule 501(a)(1), (a)(2), (a)(3), (a)(7) or (a)(8) under the
Securities Act or (ii) a “qualified institutional buyer” as defined in Rule 144A(a) under the Securities Act.

 

(d)              Experience of Such Purchaser. Such Purchaser, either alone or together with its representatives, has such
knowledge, sophistication and experience in business and financial matters so as to be capable of evaluating the merits and risks
of the prospective investment in the Securities, and has so evaluated the merits and risks of such investment. Such Purchaser is
able to bear the economic risk of an investment in the Securities and, at the present time, is able to afford a complete loss of
such investment.

 

(e)             
Access to Information. Such Purchaser acknowledges that it has had the opportunity to review the Transaction
Documents (including all exhibits and schedules thereto) and the SEC Reports and has been afforded, (i) the opportunity to ask
such questions as it has deemed necessary of, and to receive answers from, representatives of the Company concerning the terms
and conditions of the offering of the Securities and the merits and risks of investing in the Securities; (ii) access to information
about the Company and its financial condition, results of operations, business, properties, management and prospects sufficient
to enable it to evaluate its investment; and (iii) the opportunity to obtain such additional information that the Company possesses
or can acquire without unreasonable effort or expense that is necessary to make an informed investment decision with respect to
the investment.  Such Purchaser acknowledges and agrees that neither the Placement Agent nor any Affiliate of the Placement
Agent has provided such Purchaser with any information or advice with respect to the Securities nor is such information or advice
necessary or desired.  Neither the Placement Agent nor any Affiliate has made or makes any representation as to the Company
or the quality of the Securities and the Placement Agent and any Affiliate may have acquired non-public information with respect
to the Company which such Purchaser agrees need not be provided to it.  In connection with the issuance of the Securities
to such Purchaser, neither the Placement Agent nor any of its Affiliates has acted as a financial advisor or fiduciary to such
Purchaser.

 

    23

     

    

 

(f)               
Certain Transactions and Confidentiality. Other than consummating the transactions contemplated hereunder,
such Purchaser has not, nor has any Person acting on behalf of or pursuant to any understanding with such Purchaser, directly or
indirectly executed any purchases or sales, including Short Sales, of the securities of the Company during the period commencing
as of the time that such Purchaser was first contacted by the Company or any other Person representing the Company regarding the
transactions contemplated hereunder and ending immediately prior to the execution hereof. Notwithstanding the foregoing, in the
case of a Purchaser that is a multi-managed investment vehicle whereby separate portfolio managers manage separate portions of
such Purchaser’s assets and the portfolio managers have no direct knowledge of the investment decisions made by the portfolio
managers managing other portions of such Purchaser’s assets, the representation set forth above shall only apply with respect
to the portion of assets managed by the portfolio manager that made the investment decision to purchase the Securities covered
by this Agreement. Other than to other Persons party to this Agreement or to such Purchaser’s representatives, including,
without limitation, its officers, directors, partners, legal and other advisors, employees, agents and Affiliates, such Purchaser
has maintained the confidentiality of all disclosures made to it in connection with this transaction (including the existence and
terms of this transaction). Notwithstanding the foregoing, for the avoidance of doubt, nothing contained herein shall constitute
a representation or warranty, or preclude any actions, with respect to locating or borrowing shares in order to effect Short Sales
or similar transactions in the future.

 

(g)              
General Solicitation. Such Purchaser is not purchasing the Securities as a result of any advertisement, article,
notice or other communication regarding the Securities published in any newspaper, magazine or similar media or broadcast over
television or radio or presented at any seminar or, to the knowledge of such Purchaser, any other general solicitation or general
advertisement.

 

The Company acknowledges and agrees that
the representations contained in this Section 3.2 shall not modify, amend or affect such Purchaser’s right to rely on the
Company’s representations and warranties contained in this Agreement or any representations and warranties contained in any
other Transaction Document or any other document or instrument executed and/or delivered in connection with this Agreement or the
consummation of the transactions contemplated hereby.

in Section 4.1(b), the Company may require the transferor thereof to provide to the Company an opinion of counsel selected by the
transferor and reasonably acceptable to the Company, the form and substance of which opinion shall be reasonably satisfactory to
the Company, to the effect that such transfer does not require registration of such transferred Purchase Warrants or Purchase Warrant
Shares under the Securities Act.

 

(b)              
The Purchasers agree to the imprinting, so long as is required by this Section 4.1, of a legend on any of the Purchase
Warrants or Purchase Warrant Shares in the following form:

  

NEITHER THIS SECURITY NOR THE SECURITIES
INTO WHICH THIS SECURITY IS EXERCISABLE HAS BEEN REGISTERED WITH THE SECURITIES AND EXCHANGE COMMISSION OR THE SECURITIES COMMISSION
OF ANY STATE IN RELIANCE UPON AN EXEMPTION FROM REGISTRATION UNDER THE SECURITIES ACT OF 1933, AS AMENDED (THE “SECURITIES
ACT”), AND, ACCORDINGLY, MAY NOT BE OFFERED OR SOLD EXCEPT PURSUANT TO AN EFFECTIVE REGISTRATION STATEMENT UNDER THE SECURITIES
ACT OR PURSUANT TO AN AVAILABLE EXEMPTION FROM, OR IN A TRANSACTION NOT SUBJECT TO, THE REGISTRATION REQUIREMENTS OF THE SECURITIES
ACT AND IN ACCORDANCE WITH APPLICABLE STATE SECURITIES LAWS. THIS SECURITY AND THE SECURITIES ISSUABLE UPON EXERCISE OF THIS SECURITY
MAY BE PLEDGED IN CONNECTION WITH A BONA FIDE MARGIN ACCOUNT WITH A REGISTERED BROKER-DEALER OR OTHER LOAN WITH A FINANCIAL INSTITUTION
THAT IS AN “ACCREDITED INVESTOR” AS DEFINED IN RULE 501(a) UNDER THE SECURITIES ACT OR OTHER LOAN SECURED BY SUCH SECURITIES.

 

The Company acknowledges
and agrees that a Purchaser may from time to time pledge pursuant to a bona fide margin agreement with a registered broker-dealer
or grant a security interest in some or all of the Purchase Warrants or Purchase Warrant Shares to a financial institution that
is an “accredited investor” as defined in Rule 501(a) under the Securities Act and, if required under the terms of
such arrangement, such Purchaser may transfer pledged or secured Purchase Warrants or Purchase Warrant Shares to the pledgees or
secured parties. Such a pledge or transfer would not be subject to approval of the Company and no legal opinion of legal counsel
of the pledgee, secured party or pledgor shall be required in connection therewith. Further, no notice shall be required of such
pledge. At the appropriate Purchaser’s expense, the Company will execute and deliver such reasonable documentation as a pledgee
or secured party of Purchase Warrants and Purchase Warrant Shares may reasonably request in connection with a pledge or transfer
of the Purchase Warrants or Purchase Warrant Shares.

 

    25

     

    

 

 

(c)              
Certificates evidencing the Purchase Warrant Shares shall not contain any legend (including the legend set forth
in Section 4.1(b) hereof): (i) while a registration statement covering the resale of such security is effective under the Securities
Act, or (ii) following any sale of such Purchase Warrant Shares pursuant to Rule 144 (assuming cashless exercise of the Purchase
Warrants), or (iii) if such Purchase Warrant Shares are eligible for sale under Rule 144 (assuming cashless exercise of the Purchase
Warrants), or (iv) if such legend is not required under applicable requirements of the Securities Act (including judicial interpretations
and pronouncements issued by the staff of the Commission). The Company shall cause its counsel to issue a legal opinion to the
Transfer Agent or a Purchaser promptly if required by the Transfer Agent to effect the removal of the legend hereunder, or if requested
by such Purchaser; provided, however, that if any such legal opinion relates to legend removal, or sale of Securities,
pursuant to Rule 144, such opinion may be qualified in the event that the Company then fails for any reason to satisfy the current
public information requirement under Rule 144(c). If all or any portion of a Purchase Warrant is exercised at a time when there
is an effective registration statement to cover the resale of the Purchase Warrant Shares, or if such Purchase Warrant Shares may
be sold under Rule 144 (assuming cashless exercise of the Purchase Warrants) or if such legend is not otherwise required under
applicable requirements of the Securities Act (including judicial interpretations and pronouncements issued by the staff of the
Commission) then such Purchase Warrant Shares shall be issued free of all legends. The Company agrees that following such time
as such legend is no longer required under this Section 4.1(c), the Company will, no later than the earlier of (i) two (2) Trading
Days and (ii) the number of Trading Days comprising the Standard Settlement Period (as defined below) following the delivery by
a Purchaser to the Company or the Transfer Agent of a certificate representing Purchase Warrant Shares, as applicable, issued with
a restrictive legend (such date, the “Legend Removal Date”), deliver or cause to be delivered to such Purchaser
a certificate representing such shares that is free from all restrictive and other legends. The Company may not make any notation
on its records or give instructions to the Transfer Agent that enlarge the restrictions on transfer set forth in this Section 4.
Purchase Warrant Shares subject to legend removal hereunder shall be transmitted by the Transfer Agent to the Purchaser by crediting
the account of the Purchaser’s prime broker with the Depository Trust Company System as directed by such Purchaser. 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 a
certificate representing Purchase Warrant Shares issued with a restrictive legend.

 

(d)              
In addition to such Purchaser’s other available remedies, the Company shall pay to a Purchaser, in cash, (i)
as partial liquidated damages and not as a penalty, for each $1,000 of Purchase Warrant Shares (based on the VWAP of the Common
Stock on the date such securities are submitted to the Transfer Agent) delivered for removal of the restrictive legend and subject
to Section 4.1(c), $10 per Trading Day (increasing to $20 per Trading Day five (5) Trading Days after such damages have begun to
accrue) for each Trading Day after the Legend Removal Date until such certificate is delivered without a legend and (ii) if the
Company fails to (a) issue and deliver (or cause to be delivered) to a Purchaser by the Legend Removal Date a certificate representing
the securities so delivered to the Company by such Purchaser that is free from all restrictive and other legends and (b) if after
the Legend Removal Date such Purchaser purchases (in an open market transaction or otherwise) shares of Common Stock to deliver
in satisfaction of a sale by such Purchaser of all or any portion of the number of shares of Common Stock, or a sale of a number
of shares of Common Stock equal to all or any portion of the number of shares of Common Stock, that such Purchaser anticipated
receiving from the Company without any restrictive legend, then an amount equal to the excess of such Purchaser’s total purchase
price (including brokerage commissions and other out-of-pocket expenses, if any) for the shares of Common Stock so purchased (including
brokerage commissions and other out-of-pocket expenses, if any) (the “Buy-In Price”) over the product of (A)
such number of Purchase Warrant Shares that the Company was required to deliver to such Purchaser by the Legend Removal Date multiplied
by (B) the lowest closing sale price of the Common Stock on any Trading Day during the period commencing on the date of the delivery
by such Purchaser to the Company of the applicable Purchase Warrant Shares (as the case may be) and ending on the date of such
delivery and payment under this Section 4.1(d).

 

    26

     

    

 

(e)              
The Shares and Pre-Funded Warrants shall be issued free of legends. If all or any portion of a Pre-Funded Warrant
is exercised at a time when there is an effective registration statement to cover the issuance or resale of the Pre-Funded Warrant
Shares or if the Pre-Funded Warrant is exercised via cashless exercise, the Pre-Funded Warrant Shares issued pursuant to any such
exercise shall be issued free of all legends. If at any time following the date hereof the Registration Statement (or any subsequent
registration statement registering the sale or resale of the Pre-Funded Warrant Shares) is not effective or is not otherwise available
for the sale or resale of the Pre-Funded Warrant Shares, the Company shall promptly notify the holders of the Pre-Funded Warrants
in writing that such registration statement is not then effective and thereafter shall promptly notify such holders when the registration
statement is effective again and available for the sale or resale of the Pre-Funded Warrant Shares (it being understood and agreed
that the foregoing shall not limit the ability of the Company to issue, or any Purchaser to sell, any of the Pre-Funded Warrant
Shares in compliance with applicable federal and state securities laws). The Company shall use best efforts to keep a registration
statement (including the Registration Statement) registering the issuance or resale of the Pre-Funded Warrant Shares effective
during the term of the Pre-Funded Warrants.

 

4.2             
Furnishing of Information.

 

(a)              
Until the earlier of the time that (i) no Purchaser owns Securities or (ii) all of the Warrants have expired, the
Company covenants to timely file (or obtain extensions in respect thereof and file within the applicable grace period) all reports
required to be filed by the Company after the date hereof pursuant to the Exchange Act even if the Company is not then subject
to the reporting requirements of the Exchange Act.

 

(b)              
At any time during the period commencing from the date hereof and ending at such time that all of the Purchase Warrant
Shares (assuming cashless exercise) may be sold without the requirement for the Company to be in compliance with Rule 144(c)(1)
and otherwise without restriction or limitation pursuant to Rule 144, if the Company (i) shall fail for any reason to satisfy the
current public information requirement under Rule 144(c) or (ii) shall fail to satisfy any condition set forth in Rule 144(i)(2)
(a “Public Information Failure”) then, in addition to such Purchaser’s other available remedies, the Company
shall pay to a Purchaser, in cash, as partial liquidated damages and not as a penalty, by reason of any such delay in or reduction
of its ability to sell the Purchase Warrant Shares, an amount in cash equal to two percent (2.0%) of the aggregate Exercise Price
of such Purchaser’s Purchase Warrants on the day of a Public Information Failure and on every thirtieth (30th)
day (pro-rated for periods totaling less than thirty days) thereafter until the earlier of (a) the date such Public Information
Failure is cured and (b) such time that such public information is no longer required  for the Purchasers to transfer the
Purchase Warrant Shares pursuant to Rule 144.  The payments to which a Purchaser shall be entitled pursuant to this Section
4.2(b) are referred to herein as “Public Information Failure Payments.”  Public Information Failure Payments
shall be paid on the earlier of (i) the last day of the calendar month during which such Public Information Failure Payments are
incurred and (ii) the third (3rd) Business Day after the event or failure giving rise to the Public Information Failure
Payments is cured.  In the event the Company fails to make Public Information Failure Payments in a timely manner, such Public
Information Failure Payments shall bear interest at the rate of 1.5% per month (prorated for partial months) until paid in full.
Nothing herein shall limit such Purchaser’s right to pursue actual damages for the Public Information Failure, and such Purchaser
shall have the right to pursue all remedies available to it at law or in equity including, without limitation, a decree of specific
performance and/or injunctive relief.

 

    27

     

    

 

4.3             
Integration. The Company shall not sell, offer for sale or solicit offers to buy or otherwise negotiate in
respect of any security (as defined in Section 2 of the Securities Act) that would be integrated with the offer or sale of the
Securities in a manner that would require the registration under the Securities Act of the sale of the Purchase Warrants or Purchase
Warrant Shares or that would be integrated with the offer or sale of the Securities for purposes of the rules and regulations of
any Trading Market such that it would require shareholder approval prior to the closing of such other transaction unless shareholder
approval is obtained before the closing of such subsequent transaction.

 

4.4             
Securities Laws Disclosure; Publicity. The Company shall (a) by 9:00 a.m. (New York City time) on August 7,
2019, issue a press release disclosing the material terms of the transactions contemplated hereby, and (b) file a Current Report
on Form 8-K, including the Transaction Documents as exhibits thereto, with the Commission within the time required by the Exchange
Act. From and after the issuance of such press release, the Company represents to the Purchasers that it shall have publicly disclosed
all material, non-public information delivered to any of the Purchasers by the Company or any of its officers, directors, employees
or agents in connection with the transactions contemplated by the Transaction Documents. In addition, effective upon the issuance
of such press release, the Company acknowledges and agrees that any and all confidentiality or similar obligations under any agreement,
whether written or oral, between the Company or any of its officers, directors, agents, employees or Affiliates on the one hand,
and any of the Purchasers or any of their Affiliates on the other hand, shall terminate. The Company and each Purchaser shall consult
with each other in issuing any other press releases with respect to the transactions contemplated hereby, and neither the Company
nor any Purchaser shall issue any such press release nor otherwise make any such public statement without the prior consent of
the Company, with respect to any press release of any Purchaser, or without the prior consent of each Purchaser, with respect to
any press release of the Company, which consent shall not unreasonably be withheld or delayed, except if such disclosure is required
by law, in which case the disclosing party shall promptly provide the other party with prior notice of such public statement or
communication. Notwithstanding the foregoing, the Company shall not publicly disclose the name of any Purchaser, or include the
name of any Purchaser in any filing with the Commission or any regulatory agency or Trading Market, without the prior written consent
of such Purchaser, except (a) as required by federal securities law in connection with the filing of final Transaction Documents
with the Commission and (b) to the extent such disclosure is required by law or Trading Market or FINRA regulations, in which case
the Company shall provide the Purchasers with prior notice of such disclosure permitted under this clause (b).

 

    28

     

    

 

4.5             
Shareholder Rights Plan. No claim will be made or enforced by the Company or, with the consent of the Company,
any other Person, that any Purchaser is an “Acquiring Person” under any control share acquisition, business
combination, poison pill (including any distribution under a rights agreement) or similar anti-takeover plan or arrangement in
effect or hereafter adopted by the Company, or that any Purchaser could be deemed to trigger the provisions of any such plan or
arrangement, by virtue of receiving Securities under the Transaction Documents or under any other agreement between the Company
and the Purchasers.

 

4.6             
Non-Public Information. Except with respect to the material terms and conditions of the transactions contemplated
by the Transaction Documents, which shall be disclosed pursuant to Section 4.4, the Company covenants and agrees that neither it,
nor any other Person acting on its behalf will provide any Purchaser or its agents or counsel with any information that constitutes,
or the Company reasonably believes constitutes, material non-public information, unless prior thereto such Purchaser shall have
consented to the receipt of such information and agreed with the Company to keep such information confidential. The Company understands
and confirms that each Purchaser shall be relying on the foregoing covenant in effecting transactions in securities of the Company.
To the extent that the Company delivers any material, non-public information to a Purchaser without such Purchaser’s consent,
the Company hereby covenants and agrees that such Purchaser shall not have any duty of confidentiality to the Company or any of
its officers, directors, agents, employees or Affiliates, or a duty to the Company or any of its officers, directors, agents, employees
or Affiliates not to trade on the basis of, such material, non-public information, provided that the Purchaser shall remain subject
to applicable law. To the extent that any notice provided pursuant to any Transaction Document constitutes, or contains, material,
non-public information regarding the Company, the Company shall simultaneously file such notice with the Commission pursuant to
a Current Report on Form 8-K. The Company understands and confirms that each Purchaser shall be relying on the foregoing covenant
in effecting transactions in securities of the Company.

 

4.7             
Use of Proceeds. Except as set forth on Schedule 4.7 attached hereto, the Company shall use the net
proceeds from the sale of the Securities hereunder for working capital purposes and shall not use such proceeds: (a) for the satisfaction
of any portion of the Company’s debt (other than payment of trade payables in the ordinary course of the Company’s
business and prior practices and principal and interest payments required under its existing loan facility), (b) for the redemption
of any Common Stock or Common Stock Equivalents, (c) for the settlement of any outstanding litigation or (d) in violation of FCPA
or OFAC regulations.

 

    29

     

    

 

4.8             
Indemnification of Purchasers. Subject to the provisions of this Section 4.8, the Company will indemnify and
hold each Purchaser and its directors, officers, shareholders, members, partners, employees and agents (and any other Persons with
a functionally equivalent role of a Person holding such titles notwithstanding a lack of such title or any other title), each Person
who controls such Purchaser (within the meaning of Section 15 of the Securities Act and Section 20 of the Exchange Act), and the
directors, officers, shareholders, agents, members, partners or employees (and any other Persons with a functionally equivalent
role of a Person holding such titles notwithstanding a lack of such title or any other title) of such controlling persons (each,
a “Purchaser Party”) harmless from any and all losses, liabilities, obligations, claims, contingencies, damages,
costs and expenses, including all judgments, amounts paid in settlements, court costs and reasonable attorneys’ fees and
costs of investigation that any such Purchaser Party may suffer or incur as a result of or relating to (a) any breach of any of
the representations, warranties, covenants or agreements made by the Company in this Agreement or in the other Transaction Documents
or (b) any action instituted against the Purchaser Parties in any capacity, or any of them or their respective Affiliates, by any
stockholder of the Company who is not an Affiliate of such Purchaser Party, with respect to any of the transactions contemplated
by the Transaction Documents (unless such action is solely based upon a material breach of such Purchaser Party’s representations,
warranties or covenants under the Transaction Documents or any agreements or understandings such Purchaser Party may have with
any such stockholder or any violations by such Purchaser Party of state or federal securities laws or any conduct by such Purchaser
Party which is finally judicially determined to constitute fraud, gross negligence or willful misconduct) or (c) in connection
with any registration statement of the Company providing for the resale by the Purchasers of the Purchase Warrant Shares issued
and issuable upon exercise of the Purchase Warrants, the Company will indemnify each Purchaser Party, to the fullest extent permitted
by applicable law, from and against any and all losses, claims, damages, liabilities, costs (including, without limitation, reasonable
attorneys’ fees) and expenses, as incurred, arising out of or relating to (i) any untrue or alleged untrue statement of a
material fact contained in such registration statement, any prospectus or any form of prospectus or in any amendment or supplement
thereto or in any preliminary prospectus, or arising out of or relating to any omission or alleged omission of a material fact
required to be stated therein or necessary to make the statements therein (in the case of any prospectus or supplement thereto,
in the light of the circumstances under which they were made) not misleading, except to the extent, but only to the extent, that
such untrue statements or omissions are based solely upon information regarding such Purchaser Party furnished in writing to the
Company by such Purchaser Party expressly for use therein, or (ii) any violation or alleged violation by the Company of the Securities
Act, the Exchange Act or any state securities law, or any rule or regulation thereunder in connection therewith. If any action
shall be brought against any Purchaser Party in respect of which indemnity may be sought pursuant to this Agreement, such Purchaser
Party shall promptly notify the Company in writing, and the Company shall have the right to assume the defense thereof with counsel
of its own choosing reasonably acceptable to the Purchaser Party. Any Purchaser Party shall have the right to employ one separate
counsel in any such action and participate in the defense thereof, but the fees and expenses of such counsel shall be at the expense
of such Purchaser Party except to the extent that (x) the employment thereof has been specifically authorized by the Company in
writing, (y) the Company has failed after a reasonable period of time to assume such defense and to employ counsel or (z) in such
action there is, in the reasonable opinion of counsel, a material conflict on any material issue between the position of the Company
and the position of such Purchaser Party, in which case the Company shall be responsible for the reasonable fees and expenses of
no more than one such separate counsel. The Company will not be liable to any Purchaser Party under this Agreement (1) for any
settlement by a Purchaser Party effected without the Company’s prior written consent, which shall not be unreasonably withheld
or delayed; or (2) to the extent, but only to the extent that a loss, claim, damage or liability is attributable to any Purchaser
Party’s breach of any of the representations, warranties, covenants or agreements made by such Purchaser Party in this Agreement
or in the other Transaction Documents. The indemnification required by this Section 4.8 shall be made by periodic payments of the
amount thereof during the course of the investigation or defense, as and when bills are received or are incurred. The indemnity
agreements contained herein shall be in addition to any cause of action or similar right of any Purchaser Party against the Company
or others and any liabilities the Company may be subject to pursuant to law.

 

    30

     

    

 

4.9             
Reservation of Common Stock. As of the date hereof, the Company has reserved and the Company shall continue
to reserve and keep available at all times, free of preemptive rights, a sufficient number of shares of Common Stock for the purpose
of enabling the Company to issue Shares pursuant to this Agreement and Warrant Shares pursuant to any exercise of the Warrants.

 

4.10         
Listing of Common Stock. The Company hereby agrees to use best efforts to maintain the listing or quotation
of the Common Stock on the Trading Market on which it is currently listed, and prior to the Closing, the Company shall have applied
to list or quote all of the Shares and Warrant Shares on such Trading Market and concurrently with the Closing, the Company shall
have secured the listing of all of the Shares and Warrant Shares on such Trading Market. The Company further agrees, if the Company
applies to have the Common Stock traded on any other Trading Market, it will then include in such application all of the Shares
and Warrant Shares, and will take such other action as is necessary to cause all of the Shares and Warrant Shares to be listed
or quoted on such other Trading Market as promptly as possible. The Company will then take all action reasonably necessary to continue
the listing and trading of its Common Stock on a Trading Market and will comply in all respects with the Company’s reporting,
filing and other obligations under the bylaws or rules of the Trading Market. The Company agrees to maintain the eligibility of
the Common Stock for electronic transfer through the Depository Trust Company or another established clearing corporation, including,
without limitation, by timely payment of fees to the Depository Trust Company or such other established clearing corporation in
connection with such electronic transfer.

 

4.11         
Participation in Future Financing.

 

(a)              
From the date hereof until the date that is the 24 month anniversary of the Closing Date, upon any issuance by the
Company or any of its Subsidiaries of Common Stock or Common Stock Equivalents for cash consideration, Indebtedness or a combination
of units thereof (a “Subsequent Financing”), each Purchaser shall have the right to participate in up to an
amount of the Subsequent Financing equal to 50% of the Subsequent Financing (the “Participation Maximum”) on
the same terms, conditions and price provided for in the Subsequent Financing. 

 

(b)              
At least three (3) Trading Days prior to the closing of the Subsequent Financing, the Company shall deliver to each
Purchaser a written notice of its intention to effect a Subsequent Financing (“Pre-Notice”), which Pre-Notice
shall ask such Purchaser if it wants to review the details of such financing (such additional notice, a “Subsequent Financing
Notice”).  Upon the request of a Purchaser, and only upon a request by such Purchaser, for a Subsequent Financing
Notice, the Company shall promptly, but no later than one (1) Trading Day after such request, deliver a Subsequent Financing Notice
to such Purchaser.  The Subsequent Financing Notice shall describe in reasonable detail the proposed terms of such Subsequent
Financing, the amount of proceeds intended to be raised thereunder and the Person or Persons through or with whom such Subsequent
Financing is proposed to be effected, if known, and shall include any available term sheet or similar document relating thereto
as an attachment.

 

    31

     

    

 

(c)              
Any Purchaser desiring to participate in such Subsequent Financing must provide written notice to the Company by
not later than 5:30 p.m. (New York City time) on the third (3rd) Trading Day after all of the Purchasers have received
the Pre-Notice that such Purchaser is willing to participate in the Subsequent Financing, the amount of such Purchaser’s
participation, and representing and warranting that such Purchaser has such funds ready, willing, and available for investment
on the terms set forth in the Subsequent Financing Notice. If the Company receives no such notice from a Purchaser as of such third
(3rd) Trading Day, such Purchaser shall be deemed to have notified the Company that it does not elect to participate.

 

(d)              
If by 5:30 p.m. (New York City time) on the third (3rd) Trading Day after all of the Purchasers have received
the Pre-Notice, notifications by the Purchasers of their willingness to participate in the Subsequent Financing (or to cause their
designees to participate) is, in the aggregate, less than the total amount of the Subsequent Financing, then the Company may effect
the remaining portion of such Subsequent Financing on the terms and with the Persons set forth in the Subsequent Financing Notice.

 

(e)              
If by 5:30 p.m. (New York City time) on the third (3rd) Trading Day after all of the Purchasers have received
the Pre-Notice, the Company receives responses to a Subsequent Financing Notice from Purchasers seeking to purchase more than the
aggregate amount of the Participation Maximum, each such Purchaser shall have the right to purchase its Pro Rata Portion (as defined
below) of the Participation Maximum.  “Pro Rata Portion” means the ratio of (x) the Subscription Amount
of Securities purchased on the Closing Date by a Purchaser participating under this Section 4.11 and (y) the sum of the aggregate
Subscription Amounts of Securities purchased on the Closing Date by all Purchasers participating under this Section 4.11.

 

(f)               
The Company must provide the Purchasers with a second Subsequent Financing Notice, and the Purchasers will again
have the right of participation set forth above in this Section 4.11, if the Subsequent Financing subject to the initial Subsequent
Financing Notice is not consummated for any reason on the terms set forth in such Subsequent Financing Notice within thirty (30)
Trading Days after the date of the initial Subsequent Financing Notice.

 

(g)              
The Company and each Purchaser agree that if any Purchaser elects to participate in the Subsequent Financing, the
transaction documents related to the Subsequent Financing shall not include any term or provision that, directly or indirectly,
will, or is intended to, exclude one or more of the Purchasers from participating in a Subsequent Financing, including, but not
limited to, provisions whereby such Purchaser shall be required to agree to any restrictions on trading as to any of the Securities
purchased hereunder or be required to consent to any amendment to or termination of, or grant any waiver, release or the like under
or in connection with, this Agreement, without the prior written consent of such Purchaser.

 

    32

     

    

 

(h)              
Notwithstanding anything to the contrary in this Section 4.11 and unless otherwise agreed to by such Purchaser, the
Company shall either confirm in writing to such Purchaser that the transaction with respect to the Subsequent Financing has been
abandoned or shall publicly disclose its intention to issue the securities in the Subsequent Financing, in either case in such
a manner such that such Purchaser will not be in possession of any material, non-public information, by the sixth (6th)
Business Day following delivery of the Subsequent Financing Notice. If by such sixth (6th) Business Day, no public disclosure
regarding a transaction with respect to the Subsequent Financing has been made, and no notice regarding the abandonment of such
transaction has been received by such Purchaser, such transaction shall be deemed to have been abandoned and such Purchaser shall
not be deemed to be in possession of any material, non-public information with respect to the Company or any of its Subsidiaries.

 

(i)                
Notwithstanding the foregoing, this Section 4.11 shall not apply in respect of an Exempt Issuance.

 

4.12         
Subsequent Equity Sales.

 

(a)              
From the date hereof until 30 days after the Closing Date, the Company shall not issue, enter into any agreement
to issue or announce the issuance or proposed issuance of any shares of Common Stock or Common Stock Equivalents. For the avoidance
of any doubt, the Company cannot send any notice of a Subsequent Financing pursuant to Section 4.11 to the Purchasers until 30
days after the Closing Date. Additionally, for the avoidance of any doubt, the Company cannot file a registration statement until
30 days after the Closing Date.

 

(b)              
From the date hereof until such time as no Purchaser holds any of the Warrants, the Company shall be prohibited from
effecting or entering into an agreement to effect any issuance by the Company of Common Stock or Common Stock Equivalents (or a
combination of units thereof) involving a Variable Rate Transaction. “Variable Rate Transaction” means a transaction
in which the Company (i) issues or sells any debt or equity securities that are convertible into, exchangeable or exercisable for,
or include the right to receive additional shares of Common Stock either (A) at a conversion price, exercise price or exchange
rate or other price that is based upon and/or varies with the trading prices of or quotations for the shares of Common Stock at
any time after the initial issuance of such debt or equity securities, or (B) with a conversion, exercise or exchange price that
is subject to being reset at some future date after the initial issuance of such debt or equity security or upon the occurrence
of specified or contingent events directly or indirectly related to the business of the Company or the market for the Common Stock
or (ii) enters into, or effects a transaction under, any agreement, including, but not limited to, an equity line of credit, whereby
the Company may issue securities at a future determined price. Any Purchaser shall be entitled to obtain injunctive relief against
the Company to preclude any such issuance, which remedy shall be in addition to any right to collect damages.

 

    33

     

    

 

 

(c)              
Notwithstanding the foregoing, this Section 4.12 shall not apply in respect of an Exempt Issuance, except that no
Variable Rate Transaction shall be an Exempt Issuance.

 

4.13         
Equal Treatment of Purchasers. No consideration (including any modification of any Transaction Document) shall
be offered or paid to any Person to amend or consent to a waiver or modification of any provision of the Transaction Documents
unless the same consideration is also offered to all of the parties to the Transaction Documents. For clarification purposes, this
provision constitutes a separate right granted to each Purchaser by the Company and negotiated separately by each Purchaser, and
is intended for the Company to treat the Purchasers as a class and shall not in any way be construed as the Purchasers acting in
concert or as a group with respect to the purchase, disposition or voting of Securities or otherwise.

 

4.14         
Certain Transactions and Confidentiality. Each Purchaser, severally and not jointly with the other Purchasers,
covenants that neither it nor any Affiliate acting on its behalf or pursuant to any understanding with it will execute any purchases
or sales, including Short Sales of any of the Company’s securities during the period commencing with the execution of this
Agreement and ending at such time that the transactions contemplated by this Agreement are first publicly announced pursuant to
the initial press release as described in Section 4.4.  Each Purchaser, severally and not jointly with the other Purchasers,
covenants that until such time as the transactions contemplated by this Agreement are publicly disclosed by the Company pursuant
to the initial press release as described in Section 4.4, such Purchaser will maintain the confidentiality of the existence and
terms of this transaction and the information included in the Disclosure Schedules.  Notwithstanding the foregoing and notwithstanding
anything contained in this Agreement to the contrary, the Company expressly acknowledges and agrees that (i) no Purchaser makes
any representation, warranty or covenant hereby that it will not engage in effecting transactions in any securities of the Company
after the time that the transactions contemplated by this Agreement are first publicly announced pursuant to the initial press
release as described in Section 4.4, (ii) no Purchaser shall be restricted or prohibited from effecting any transactions in any
securities of the Company in accordance with applicable securities laws from and after the time that the transactions contemplated
by this Agreement are first publicly announced pursuant to the initial press release as described in Section 4.4 and (iii) no Purchaser
shall have any duty of confidentiality or duty not to trade in the securities of the Company to the Company after the issuance
of the initial press release as described in Section 4.4.  Notwithstanding the foregoing, in the case of a Purchaser that
is a multi-managed investment vehicle whereby separate portfolio managers manage separate portions of such Purchaser’s assets
and the portfolio managers have no direct knowledge of the investment decisions made by the portfolio managers managing other portions
of such Purchaser’s assets, the covenant set forth above shall only apply with respect to the portion of assets managed by
the portfolio manager that made the investment decision to purchase the Securities covered by this Agreement.

 

4.15         
Exercise Procedures. The form of Notice of Exercise included in each of the Warrants sets forth the totality
of the procedures required of the Purchasers in order to exercise the Warrants. No additional legal opinion, other information
or instructions shall be required of the Purchasers to exercise their Warrants. Without limiting the preceding sentences, 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 in order to exercise the Warrants. The Company shall honor exercises of the Warrants and shall deliver
Warrant Shares in accordance with the terms, conditions and time periods set forth in the Transaction Documents.

4.16         
Form D; Blue Sky Filings. The Company agrees to timely file a Form D with respect to the Purchase Warrants
and Purchase Warrant Shares as required under Regulation D and to provide a copy thereof, promptly upon request of any Purchaser.
The Company shall take such action as the Company shall reasonably determine is necessary in order to obtain an exemption for,
or to qualify the Purchase Warrants and Purchase Warrant Shares for, sale to the Purchasers at the Closing under applicable securities
or “Blue Sky” laws of the states of the United States, and shall provide evidence of such actions promptly upon request
of any Purchaser.

 

4.17         
Registration Statement. Within 120 calendar days of the date of this Agreement), the Company shall file a
registration statement on Form S-3 (or other appropriate form if necessary to comply with General Instruction I.B.6. of Form S-3)
providing for the resale by the Purchasers of the Purchase Warrant Shares issued and issuable upon exercise of the Purchase Warrants. 
The Company shall use commercially reasonable efforts to cause such registration to become effective within 181 days following
the Closing Date and to keep such registration statement effective at all times until no Purchaser owns any Purchase Warrants or
Purchase Warrant Shares issuable upon exercise thereof.

 

4.18         
Capital Changes. Until the one year anniversary of the Closing Date, the Company shall not undertake a reverse
or forward stock split or reclassification of the Common Stock without the prior written consent of the Purchasers holding a majority
in interest of the Shares, other than a stock split that is required, in the good faith judgment of the Board of Directors, to
maintain the listing of the Common Stock on the current Trading Market.

5.1             
Termination.  This Agreement may be terminated by any Purchaser, as to such Purchaser’s obligations
hereunder only and without any effect whatsoever on the obligations between the Company and the other Purchasers, by written notice
to the other parties, if the Closing has not been consummated on or before the fifth (5th) Trading Day following the
date hereof; provided, however, that no such termination will affect the right of any party to sue for any breach
by any other party (or parties).

 

5.2             
Fees and Expenses. At the Closing, the Company has agreed to reimburse Sabby Management, LLC the non-accountable
sum of $10,000 for its legal fees and expenses. Except as expressly set forth in the Transaction Documents to the contrary, each
party shall pay the fees and expenses of its advisers, counsel, accountants and other experts, if any, and all other expenses incurred
by such party incident to the negotiation, preparation, execution, delivery and performance of this Agreement. The Company shall
pay all Transfer Agent fees (including, without limitation, any fees required for same-day processing of any instruction letter
delivered by the Company and any exercise notice delivered by a Purchaser), stamp taxes and other taxes and duties levied in connection
with the delivery of any Securities to the Purchasers.

 

    35

     

    

 

5.3             
Entire Agreement. The Transaction Documents, together with the exhibits and schedules thereto, the Prospectus
and the Prospectus Supplement, contain the entire understanding of the parties with respect to the subject matter hereof and thereof
and supersede all prior agreements and understandings, oral or written, with respect to such matters, which the parties acknowledge
have been merged into such documents, exhibits and schedules.

 

5.4             
Notices. Any and all notices or other communications or deliveries required or permitted to be provided hereunder
shall be in writing and shall be deemed given and effective on the earliest of: (a) the time of transmission, if such notice or

provided pursuant to any Transaction Document constitutes, or contains, material, non-public information regarding the Company,
the Company shall simultaneously file such notice with the Commission pursuant to a Current Report on Form 8-K.

 

5.5             
Amendments; Waivers. No provision of this Agreement may be waived, modified, supplemented or amended except
in a written instrument signed, in the case of an amendment, by the Company and Purchasers which purchased at least 50.1% in interest
of the Shares based on the initial Subscription Amounts hereunder or, in the case of a waiver, by the party against whom enforcement
of any such waived provision is sought, provided that if any amendment, modification or waiver disproportionately and adversely
impacts a Purchaser (or group of Purchasers), the consent of such disproportionately impacted Purchaser (or group of Purchasers)
shall also be required. No waiver of any default with respect to any provision, condition or requirement of this Agreement shall
be deemed to be a continuing waiver in the future or a waiver of any subsequent default or a waiver of any other provision, condition
or requirement hereof, nor shall any delay or omission of any party to exercise any right hereunder in any manner impair the exercise
of any such right. Any proposed amendment or waiver that disproportionately, materially and adversely affects the rights and obligations
of any Purchaser relative to the comparable rights and obligations of the other Purchasers shall require the prior written consent
of such adversely affected Purchaser. Any amendment effected in accordance with this Section 5.5 shall be binding upon each Purchaser
and holder of Securities and the Company.

 

5.6             
Headings. The headings herein are for convenience only, do not constitute a part of this Agreement and shall
not be deemed to limit or affect any of the provisions hereof.

 

5.7             
Successors and Assigns. This Agreement shall be binding upon and inure to the benefit of the parties and their
successors and permitted assigns. The Company may not assign this Agreement or any rights or obligations hereunder without the
prior written consent of each Purchaser (other than by merger). Any Purchaser may assign any or all of its rights under this Agreement
to any Person to whom such Purchaser assigns or transfers any Securities, provided that such transferee agrees in writing to be
bound, with respect to the transferred Securities, by the provisions of the Transaction Documents that apply to the “Purchasers.”

 

    36

     

    

 

5.8             
Third-Party Beneficiaries. The Placement Agent shall be the third party beneficiary of the representations
and warranties of the Company in Section 3.1 and the representations and warranties of the Purchasers in Section 3.2. This Agreement
is intended for the benefit of the parties hereto and their respective successors and permitted assigns and is not for the benefit
of, nor may any provision hereof be enforced by, any other Person, except as otherwise set forth in Section 4.8, this Section 5.8
and/or the Placement Agency Agreement.

 

5.9             
Governing Law. All questions concerning the construction, validity, enforcement and interpretation of the
Transaction Documents 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 Agreement and any other Transaction Documents
(whether brought against a party hereto or its 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
(including with respect to the enforcement of any of the Transaction Documents), and hereby irrevocably waives, and agrees not
to assert in any Action or Proceeding, any claim that it is not personally subject to the jurisdiction of any such court, that
such 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 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 Agreement 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 any party
shall commence an Action or Proceeding to enforce any provisions of the Transaction Documents, then, in addition to the obligations
of the Company under Section 4.8, the prevailing party in such Action or Proceeding shall be reimbursed by the non-prevailing party
for its reasonable attorneys’ fees and other costs and expenses incurred with the investigation, preparation and prosecution
of such Action or Proceeding.

 

5.10           
Survival. The representations and warranties contained herein shall survive the Closing and the delivery of
the Securities.

 

5.11           
Execution. This Agreement may be executed in two or more counterparts, all of which when taken together shall
be considered one and the same agreement and shall become effective when counterparts have been signed by each party and delivered
to each other party, it being understood that the parties need not sign the same counterpart. In the event that any signature is
delivered by facsimile transmission or by e-mail delivery of a “.pdf” format data file, such signature shall create
a valid and binding obligation of the party executing (or on whose behalf such signature is executed) with the same force and effect
as if such facsimile or “.pdf” signature page were an original thereof.

 

    37

     

    

 

5.12          
Severability. If any term, provision, covenant or restriction of this Agreement is held by a court of competent
jurisdiction to be invalid, illegal, void or unenforceable, the remainder of the terms, provisions, covenants and restrictions
set forth herein shall remain in full force and effect and shall in no way be affected, impaired or invalidated, and the parties
hereto shall use their commercially reasonable efforts to find and employ an alternative means to achieve the same or substantially
the same result as that contemplated by such term, provision, covenant or restriction. It is hereby stipulated and declared to
be the intention of the parties that they would have executed the remaining terms, provisions, covenants and restrictions without
including any of such that may be hereafter declared invalid, illegal, void or unenforceable.

 

5.13           
Rescission and Withdrawal Right. Notwithstanding anything to the contrary contained in (and without limiting
any similar provisions of) any of the other Transaction Documents, whenever any Purchaser exercises a right, election, demand or
option under a Transaction Document and the Company does not timely perform its related obligations within the periods therein
provided, then such Purchaser may rescind or withdraw, in its sole discretion from time to time upon written notice to the Company,
any relevant notice, demand or election in whole or in part without prejudice to its future actions and rights; provided,
however, that in the case of a rescission of an exercise of a Warrant, the applicable Purchaser shall be required to return
any shares of Common Stock subject to any such rescinded exercise notice concurrently with the return to such Purchaser of the
aggregate exercise price paid to the Company for such shares and the restoration of such Purchaser’s right to acquire such
shares pursuant to such Purchaser’s Warrant (including, issuance of a replacement warrant certificate evidencing such restored
right).

 

5.14           
Replacement of Securities. If any certificate or instrument evidencing any Securities is mutilated, lost,
stolen or destroyed, the Company shall issue or cause to be issued in exchange and substitution for and upon cancellation thereof
(in the case of mutilation), or in lieu of and substitution therefor, a new certificate or instrument, but only upon receipt of
evidence reasonably satisfactory to the Company of such loss, theft or destruction. The applicant for a new certificate or instrument
under such circumstances shall also pay any reasonable third-party costs (including customary indemnity) associated with the issuance
of such replacement Securities.

 

5.15           
Remedies. In addition to being entitled to exercise all rights provided herein or granted by law, including
recovery of damages, each of the Purchasers and the Company will be entitled to specific performance under the Transaction Documents.
The parties agree that monetary damages may not be adequate compensation for any loss incurred by reason of any breach of obligations
contained in the Transaction Documents and hereby agree to waive and not to assert in any Action for specific performance of any
such obligation the defense that a remedy at law would be adequate.

 

5.16           
Payment Set Aside. To the extent that the Company makes a payment or payments to any Purchaser pursuant to
any Transaction Document or a Purchaser enforces or exercises its rights thereunder, and such payment or payments or the proceeds
of such enforcement or exercise or any part thereof are subsequently invalidated, declared to be fraudulent or preferential, set
aside, recovered from, disgorged by or are required to be refunded, repaid or otherwise restored to the Company, a trustee, receiver
or any other Person under any law (including, without limitation, any bankruptcy law, state or federal law, common law or equitable
cause of action), then to the extent of any such restoration the obligation or part thereof originally intended to be satisfied
shall be revived and continued in full force and effect as if such payment had not been made or such enforcement or setoff had
not occurred.

 

    38

     

    

 

5.17           
Independent Nature of Purchasers’ Obligations and Rights. The obligations of each Purchaser under any
Transaction Document are several and not joint with the obligations of any other Purchaser, and no Purchaser shall be responsible
in any way for the performance or non-performance of the obligations of any other Purchaser under any Transaction Document. Nothing
contained herein or in any other Transaction Document, and no action taken by any Purchaser pursuant hereto or thereto, shall be
deemed to constitute the Purchasers as a partnership, an association, a joint venture or any other kind of entity, or create a
presumption that the Purchasers are in any way acting in concert or as a group with respect to such obligations or the transactions
contemplated by the Transaction Documents. Each Purchaser shall be entitled to independently protect and enforce its rights including,
without limitation, the rights arising out of this Agreement or out of the other Transaction Documents, and it shall not be necessary
for any other Purchaser to be joined as an additional party in any Proceeding for such purpose. Each Purchaser has been represented
by its own separate legal counsel in its review and negotiation of the Transaction Documents. For reasons of administrative convenience
only, each Purchaser and its respective counsel have chosen to communicate with the Company through Agent’s Counsel. Agent’s
Counsel does not represent any of the Purchasers and only represents the Placement Agent. The Company has elected to provide all
Purchasers with the same terms and Transaction Documents for the convenience of the Company and not because it was required or
requested to do so by any of the Purchasers. It is expressly understood and agreed that each provision contained in this Agreement
and in each other Transaction Document is between the Company and a Purchaser, solely, and not between the Company and the Purchasers
collectively and not between and among the Purchasers.

 

5.18           
Liquidated Damages. The Company’s obligations to pay any partial liquidated damages or other amounts
owing under the Transaction Documents is a continuing obligation of the Company and shall not terminate until all unpaid partial
liquidated damages and other amounts have been paid notwithstanding the fact that the instrument or security pursuant to which
such partial liquidated damages or other amounts are due and payable shall have been canceled.

 

5.19           
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.

 

5.20           
Construction. The parties agree that each of them and/or their respective counsel have reviewed and had an
opportunity to revise the Transaction Documents and, therefore, the normal rule of construction to the effect that any ambiguities
are to be resolved against the drafting party shall not be employed in the interpretation of the Transaction Documents or any amendments
thereto. In addition, each and every reference to share prices and shares of Common Stock in any Transaction Document shall be
subject to adjustment for reverse and forward stock splits, stock dividends, stock combinations and other similar transactions
of the Common Stock that occur after the date of this Agreement.

 

    39

     

    

 

5.21           
WAIVER OF JURY TRIAL. IN ANY ACTION, SUIT, OR PROCEEDING IN ANY JURISDICTION BROUGHT BY ANY PARTY AGAINST ANY
OTHER PARTY, THE PARTIES EACH KNOWINGLY AND INTENTIONALLY, TO THE GREATEST EXTENT PERMITTED BY APPLICABLE LAW, HEREBY ABSOLUTELY,
UNCONDITIONALLY, IRREVOCABLY AND EXPRESSLY WAIVES FOREVER TRIAL BY JURY.
