Warrant To Purchase Common
Stock

 

Warrant No.: [__]

 

Date of Issuance: January 25, 2021 (“Issuance
Date”)

 

Aditx Therapeutics,
Inc., a Delaware corporation (the “Company”), hereby certifies that, for good and valuable consideration, the
receipt and sufficiency of which are hereby acknowledged, [__], the registered holder hereof or its permitted assigns (the “Holder”),
is entitled, subject to the terms set forth below, to purchase from the Company, at the Exercise Price (as defined below) then
in effect, upon exercise of this Warrant to Purchase Common Stock (including any Warrants to Purchase Common Stock issued in exchange,
transfer or replacement hereof, the “Warrant”), at any time or times on or after the Issuance Date, but not
after 11:59 p.m., New York time, on the Expiration Date (as defined below), Eight Hundred Thousand (800,000) (subject to adjustment
as provided herein) fully paid and non-assessable shares of Common Stock (as defined below) (the “Warrant Shares”,
and such number of Warrant Shares, the “Warrant Number”). Except as otherwise defined herein, capitalized terms
in this Warrant shall have the meanings set forth in Section 19. This Warrant is one of the Warrants to Purchase Common Stock
(the “SPA Warrants”) issued pursuant to Section 1 of that certain Securities Purchase Agreement, dated
as of January 25, 2021 (the “Subscription Date”), by and among the Company and the investors (the “Buyers”)
referred to therein, as amended from time to time (the “Securities Purchase Agreement”).

 

    

     

    

 

1. EXERCISE
OF WARRANT.

 

(a) Mechanics
of Exercise. Subject to the terms and conditions hereof (including, without limitation, the limitations set forth in Section 1(f)),
this Warrant may be exercised by the Holder on any day on or after the Issuance Date (an “Exercise Date”), in
whole or in part, by delivery (whether via facsimile or otherwise) of a written notice, in the form attached hereto as Exhibit
A (the “Exercise Notice”), of the Holder’s election to exercise this Warrant. Within one (1) Trading
Day following an exercise of this Warrant as aforesaid, the Holder shall deliver payment to the Company of an amount equal to the
Exercise Price in effect on the date of such exercise multiplied by the number of Warrant Shares as to which this Warrant was so
exercised (the “Aggregate Exercise Price”) in cash or via wire transfer of immediately available funds if the
Holder did not notify the Company in such Exercise Notice that such exercise was made pursuant to a Cashless Exercise (as defined
in Section 1(d)). The Holder shall not be required to deliver the original of this Warrant in order to effect an exercise
hereunder. Execution and delivery of an Exercise Notice with respect to less than all of the Warrant Shares shall have the same
effect as cancellation of the original of this Warrant and issuance of a new Warrant evidencing the right to purchase the remaining
number of Warrant Shares. Execution and delivery of an Exercise Notice for all of the then-remaining Warrant Shares shall have
the same effect as cancellation of the original of this Warrant after delivery of the Warrant Shares in accordance with the terms
hereof. On or before the first (1st) Trading Day following the date on which the Company has received an Exercise Notice,
the Company shall transmit by facsimile or electronic mail an acknowledgment of confirmation of receipt of such Exercise Notice,
in the form attached hereto as Exhibit B, to the Holder and the Company’s transfer agent (the “Transfer
Agent”), which confirmation shall constitute an instruction to the Transfer Agent to process such Exercise Notice in
accordance with the terms herein. On or before the second (2nd) Trading Day following the date on which the Company
has received such Exercise Notice (or such earlier date as required pursuant to the 1934 Act or other applicable law, rule or regulation
for the settlement of a trade of such Warrant Shares initiated on the applicable Exercise Date), the Company shall (X) provided
that the Transfer Agent is participating in The Depository Trust Company (“DTC”) Fast Automated Securities Transfer
Program, upon the request of the Holder, credit such aggregate number of shares of Common Stock to which the Holder is entitled
pursuant to such exercise to the Holder’s or its designee’s balance account with DTC through its Deposit/Withdrawal
at Custodian system, or (Y) if the Transfer Agent is not participating in the DTC Fast Automated Securities Transfer Program, upon
the request of the Holder, issue and deliver (via reputable overnight courier) to the address as specified in the Exercise Notice,
a certificate, registered in the name of the Holder or its designee, for the number of shares of Common Stock to which the Holder
shall be entitled pursuant to such exercise. Upon delivery of an Exercise Notice, 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 such Warrant Shares are credited to the Holder’s DTC account or the date of delivery of the certificates evidencing
such Warrant Shares (as the case may be). If this Warrant is submitted in connection with any exercise pursuant to this Section 1(a)
and the number of Warrant Shares represented by this Warrant submitted for exercise is greater than the number of Warrant Shares
being acquired upon an exercise and upon surrender of this Warrant to the Company by the Holder, then, at the request of the Holder,
the Company shall as soon as practicable and in no event later than two (2) Business Days after any exercise and at its own expense,
issue and deliver to the Holder (or its designee) a new Warrant (in accordance with Section 7(d)) representing the right to
purchase the number of Warrant Shares purchasable immediately prior to such exercise under this Warrant, less the number of Warrant
Shares with respect to which this Warrant is exercised. No fractional shares of Common Stock are to be issued upon the exercise
of this Warrant, but rather the number of shares of Common Stock to be issued shall be rounded up to the nearest whole number.
The Company shall pay any and all transfer, stamp, issuance and similar taxes, costs and expenses (including, without limitation,
fees and expenses of the Transfer Agent) that may be payable with respect to the issuance and delivery of Warrant Shares upon exercise
of this Warrant. Notwithstanding the foregoing, except in the case where an exercise of this Warrant is validly made pursuant to
a Cashless Exercise, the Company’s failure to deliver Warrant Shares to the Holder on or prior to the later of (i) two (2)
Trading Days after receipt of the applicable Exercise Notice (or such earlier date as required pursuant to the 1934 Act or other
applicable law, rule or regulation for the settlement of a trade of such Warrant Shares initiated on the applicable Exercise Date)
and (ii) one (1) Trading Day after the Company’s receipt of the Aggregate Exercise Price (or valid notice of a Cashless Exercise)
(such later date, the “Share Delivery Date”) shall not be deemed to be a breach of this Warrant. Notwithstanding
anything to the contrary contained in this Warrant or the Registration Rights Agreement, after the effective date of the Registration
Statement (as defined in the Registration Rights Agreement) and prior to the Holder’s receipt of the notice of a Grace Period
(as defined in the Registration Rights Agreement), the Company shall cause the Transfer Agent to deliver unlegended shares of Common
Stock to the Holder (or its designee) in connection with any sale of Registrable Securities (as defined in the Registration Rights
Agreement) with respect to which the Holder has entered into a contract for sale, and delivered a copy of the prospectus included
as part of the particular Registration Statement to the extent applicable, and for which the Holder has not yet settled. From the
Issuance Date through and including the Expiration Date, the Company shall maintain a transfer agent that participates in the DTC’s
Fast Automated Securities Transfer Program.

 

(b) Exercise
Price. For purposes of this Warrant, “Exercise Price” means $4.00, subject to adjustment as provided herein.

(c) Company’s
Failure to Timely Deliver Securities. If the Company shall fail, for any reason or for no reason, on or prior to the Share
Delivery Date, either (I) if the Transfer Agent is not participating in the DTC Fast Automated Securities Transfer Program, to
issue and deliver to the Holder (or its designee) a certificate for the number of Warrant Shares to which the Holder is entitled
and register such Warrant Shares on the Company’s share register or, if the Transfer Agent is participating in the DTC Fast
Automated Securities Transfer Program, to credit the balance account of the Holder or the Holder’s designee with DTC for
such number of Warrant Shares to which the Holder is entitled upon the Holder’s exercise of this Warrant (as the case may
be) or (II) if a Registration Statement covering the resale of the Warrant Shares that are the subject of the Exercise Notice (the
“Unavailable Warrant Shares”) is not available for the resale of such Unavailable Warrant Shares and the Company
fails to promptly, but in no event later than as required pursuant to the Registration Rights Agreement (x) so notify the Holder
and (y) deliver the Warrant Shares electronically without any restrictive legend by crediting such aggregate number of Warrant
Shares to which the Holder is entitled pursuant to such exercise to the Holder’s or its designee’s balance account
with DTC through its Deposit/Withdrawal At Custodian system (the event described in the immediately foregoing clause (II) is hereinafter
referred as a “Notice Failure” and together with the event described in clause (I) above, a “Delivery
Failure”), then, in addition to all other remedies available to the Holder, (X) the Company shall pay in cash to the
Holder on each day after the Share Delivery Date and during such Delivery Failure an amount equal to 2% of the product of (A) the
sum of the number of shares of Common Stock not issued to the Holder on or prior to the Share Delivery Date and to which the Holder
is entitled, multiplied by (B) any trading price of the Common Stock selected by the Holder in writing as in effect at any time
during the period beginning on the applicable Exercise Date and ending on the applicable Share Delivery Date, and (Y) the Holder,
upon written notice to the Company, may void its Exercise Notice with respect to, and retain or have returned, as the case may
be, any portion of this Warrant that has not been exercised pursuant to such Exercise Notice; provided that the voiding of an Exercise
Notice shall not affect the Company’s obligations to make any payments which have accrued prior to the date of such notice
pursuant to this Section 1(c) or otherwise. In addition to the foregoing, if on or prior to the Share Delivery Date either (I)
the Transfer Agent is not participating in the DTC Fast Automated Securities Transfer Program, the Company shall fail to issue
and deliver to the Holder (or its designee) a certificate and register such shares of Common Stock on the Company’s share
register or, if the Transfer Agent is participating in the DTC Fast Automated Securities Transfer Program, the Transfer Agent shall
fail to credit the balance account of the Holder or the Holder’s designee with DTC for the number of shares of Common Stock
to which the Holder is entitled upon the Holder’s exercise hereunder or pursuant to the Company’s obligation pursuant
to clause (ii) below or (II) a Notice Failure occurs, and if on or after such Share Delivery Date the Holder purchases (in an open
market transaction or otherwise) shares of Common Stock corresponding to all or any portion of the number of shares of Common Stock
issuable upon such exercise that the Holder is entitled to receive from the Company and has not received from the Company in connection
with such Delivery Failure or Notice Failure, as applicable (a “Buy-In”), then, in addition to all other remedies
available to the Holder, the Company shall, within two (2) Business Days after the Holder’s request and in the Holder’s
discretion, either (i) pay cash to the Holder in an amount equal to the Holder’s total purchase price (including brokerage
commissions and other out-of-pocket expenses, if any) for the shares of Common Stock so purchased (including, without limitation,
by any other Person in respect, or on behalf, of the Holder) (the “Buy-In Price”), at which point the Company’s
obligation to so issue and deliver such certificate (and to issue such shares of Common Stock) or credit the balance account of
such Holder or such Holder’s designee, as applicable, with DTC for the number of Warrant Shares to which the Holder is entitled
upon the Holder’s exercise hereunder (as the case may be) (and to issue such Warrant Shares) shall terminate, or (ii) promptly
honor its obligation to so issue and deliver to the Holder a certificate or certificates representing such Warrant Shares or credit
the balance account of such Holder or such Holder’s designee, as applicable, with DTC for the number of Warrant Shares to
which the Holder is entitled upon the Holder’s exercise hereunder (as the case may be) and pay cash to the Holder in an amount
equal to the excess (if any) of the Buy-In Price over the product of (A) such number of Warrant Shares 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 applicable Exercise Notice
and ending on the date of such issuance and payment under this clause (ii) (the “Buy-In Payment Amount”). Nothing
shall limit the 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
certificates representing shares of Common Stock (or to electronically deliver such shares of Common Stock) upon the exercise of
this Warrant as required pursuant to the terms hereof. While this Warrant is outstanding, the Company shall cause its transfer
agent to participate in the DTC Fast Automated Securities Transfer Program. In addition to the foregoing rights, (i) if the Company
fails to deliver the applicable number of Warrant Shares upon an exercise pursuant to Section 1 by the applicable Share Delivery
Date, then the Holder shall have the right to rescind such exercise in whole or in part and retain and/or have the Company return,
as the case may be, any portion of this Warrant that has not been exercised pursuant to such Exercise Notice; provided that the
rescission of an exercise shall not affect the Company’s obligation to make any payments that have accrued prior to the date
of such notice pursuant to this Section 1(c) or otherwise, and (ii) if a registration statement covering the issuance or resale
of the Warrant Shares that are subject to an Exercise Notice is not available for the issuance or resale, as applicable, of such
Warrant Shares and the Holder has submitted an Exercise Notice prior to receiving notice of the non-availability of such registration
statement and the Company has not already delivered the Warrant Shares underlying such Exercise Notice electronically without any
restrictive legend by crediting such aggregate number of Warrant Shares to which the Holder is entitled pursuant to such exercise
to the Holder’s or its designee’s balance account with DTC through its Deposit / Withdrawal At Custodian system, the
Holder shall have the option, by delivery of notice to the Company, to (x) rescind such Exercise Notice in whole or in part and
retain or have returned, as the case may be, any portion of this Warrant that has not been exercised pursuant to such Exercise
Notice; provided that the rescission of an Exercise Notice shall not affect the Company’s obligation to make any payments
that have accrued prior to the date of such notice pursuant to this Section 1(c), or otherwise, and/or (y) switch some or all of
such Exercise Notice from a cash exercise to a Cashless Exercise.

 

    3

     

    

 

(d) Cashless
Exercise. Notwithstanding anything contained herein to the contrary (other than Section 1(f) below), if after a period
of one hundred and eighty (180) days after the Date of Issuance of this Warrant, at the time of exercise hereof a Registration
Statement (as defined in the Registration Rights Agreement) is not effective (or the prospectus contained therein is not available
for use) for the resale by the Holder of all of the Warrant Shares, then the Holder may, in its sole discretion, exercise this
Warrant in whole or in part and, in lieu of making the cash payment otherwise contemplated to be made to the Company upon such
exercise in payment of the Aggregate Exercise Price, elect instead to receive upon such exercise the “Net Number” of
Warrant Shares determined according to the following formula (a “Cashless Exercise”):

 

Net Number = (A x B) - (A x C)

D

 

For purposes of the
foregoing formula:

 

A= the total number of shares with
respect to which this Warrant is then being exercised.

 

B = the VWAP of the shares of Common
Stock at the close of business on the Principal Market as of the Trading Day immediately prior to the date of the delivery of the
applicable Exercise Notice.

 

C = the
Exercise Price then in effect for the applicable Warrant Shares at the time of such exercise.

 

D = the VWAP of the shares of Common
Stock at the close of business on the Principal Market on the date of the delivery of the applicable Exercise Notice.

 

If the Warrant Shares
are issued in a Cashless Exercise, the parties acknowledge and agree that in accordance with Section 3(a)(9) of the 1933 Act, the
Warrant Shares take on the registered characteristics of the Warrants being exercised. For purposes of Rule 144(d) promulgated
under the 1933 Act, as in effect on the Subscription Date, it is intended that the Warrant Shares issued in a Cashless Exercise
shall be deemed to have been acquired by the Holder, and the holding period for the Warrant Shares shall be deemed to have commenced,
on the date this Warrant was originally issued pursuant to the Securities Purchase Agreement.

 

(e) Disputes.
In the case of a dispute as to the determination of the Exercise Price or the arithmetic calculation of the number of Warrant Shares
to be issued pursuant to the terms hereof, the Company shall promptly issue to the Holder the number of Warrant Shares that are
not disputed and resolve such dispute in accordance with Section 15.

 

    4

     

    

 

(f) Limitations
on Exercises.

 

(i) Beneficial
Ownership. The Company shall not effect the exercise of any portion of this Warrant, and the Holder shall not have the right
to exercise any portion of this Warrant, pursuant to the terms and conditions of this Warrant and any such exercise shall be null
and void and treated as if never made, to the extent that after giving effect to such exercise, the Holder together with the other
Attribution Parties collectively would beneficially own in excess of 4.99% (the “Maximum Percentage”) of the
shares of Common Stock outstanding immediately after giving effect to such exercise. For purposes of the foregoing sentence, the
aggregate number of shares of Common Stock beneficially owned by the Holder and the other Attribution Parties shall include the
number of shares of Common Stock held by the Holder and all other Attribution Parties plus the number of shares of Common Stock
issuable upon exercise of this Warrant with respect to which the determination of such sentence is being made, but shall exclude
shares of Common Stock which would be issuable upon (A) exercise of the remaining, unexercised portion of this Warrant beneficially
owned by the Holder or any of the other Attribution Parties and (B) exercise or conversion of the unexercised or unconverted portion
of any other securities of the Company (including, without limitation, any convertible notes or convertible preferred stock or
warrants, including other SPA Warrants) beneficially owned by the Holder or any other Attribution Party subject to a limitation
on conversion or exercise analogous to the limitation contained in this Section 1(f)(i). For purposes of this Section 1(f)(i),
beneficial ownership shall be calculated in accordance with Section 13(d) of the 1934 Act. For purposes of determining the number
of outstanding shares of Common Stock the Holder may acquire upon the exercise of this Warrant without exceeding the Maximum Percentage,
the Holder may rely on the number of outstanding shares of Common Stock as reflected in (x) the Company’s most recent Annual
Report on Form 10-K, Quarterly Report on Form 10-Q, Current Report on Form 8-K or other public filing with the SEC, as the case
may be, (y) a more recent public announcement by the Company or (z) any other written notice by the Company or the Transfer Agent,
if any, setting forth the number of shares of Common Stock outstanding (the “Reported Outstanding Share Number”).
If the Company receives an Exercise Notice from the Holder at a time when the actual number of outstanding shares of Common Stock
is less than the Reported Outstanding Share Number, the Company shall (i) notify the Holder in writing of the number of shares
of Common Stock then outstanding and, to the extent that such Exercise Notice would otherwise cause the Holder’s beneficial
ownership, as determined pursuant to this Section 1(f)(i), to exceed the Maximum Percentage, the Holder must notify the Company
of a reduced number of Warrant Shares to be acquired pursuant to such Exercise Notice (the number of shares by which such purchase
is reduced, the “Reduction Shares”) and (ii) as soon as reasonably practicable, the Company shall return to
the Holder any exercise price paid by the Holder for the Reduction Shares. For any reason at any time, upon the written or oral
request of the Holder, the Company shall within one (1) Business Day confirm orally and in writing or by electronic mail to the
Holder the number of shares of Common Stock then outstanding. In any case, the number of outstanding shares of Common Stock shall
be determined after giving effect to the conversion or exercise of securities of the Company, including this Warrant, by the Holder
and any other Attribution Party since the date as of which the Reported Outstanding Share Number was reported. In the event that
the issuance of shares of Common Stock to the Holder upon exercise of this Warrant results in the Holder and the other Attribution
Parties being deemed to beneficially own, in the aggregate, more than the Maximum Percentage of the number of outstanding shares
of Common Stock (as determined under Section 13(d) of the 1934 Act), the number of shares so issued by which the Holder’s
and the other Attribution Parties’ aggregate beneficial ownership exceeds the Maximum Percentage (the “Excess Shares”)
shall be deemed null and void and shall be cancelled ab initio, and the Holder shall not have the power to vote or to transfer
the Excess Shares. As soon as reasonably practicable after the issuance of the Excess Shares has been deemed null and void, the
Company shall return to the Holder the exercise price paid by the Holder for the Excess Shares. Upon delivery of a written notice
to the Company, the Holder may from time to time increase (with such increase not effective until the sixty-first (61st)
day after delivery of such notice) or decrease the Maximum Percentage to any other percentage not in excess of 9.99% as specified
in such notice; provided that (i) any such increase in the Maximum Percentage will not be effective until the sixty-first (61st)
day after such notice is delivered to the Company and (ii) any such increase or decrease will apply only to the Holder and the
other Attribution Parties and not to any other holder of SPA Warrants that is not an Attribution Party of the Holder. For purposes
of clarity, the shares of Common Stock issuable pursuant to the terms of this Warrant in excess of the Maximum Percentage shall
not be deemed to be beneficially owned by the Holder for any purpose including for purposes of Section 13(d) or Rule 16a-1(a)(1)
of the 1934 Act. No prior inability to exercise this Warrant pursuant to this paragraph shall have any effect on the applicability
of the provisions of this paragraph with respect to any subsequent determination of exercisability. The provisions of this paragraph
shall be construed and implemented in a manner otherwise than in strict conformity with the terms of this Section 1(f)(i) to the
extent necessary to correct this paragraph or any portion of this paragraph which may be defective or inconsistent with the intended
beneficial ownership limitation contained in this Section 1(f)(i) or to make changes or supplements necessary or desirable to properly
give effect to such limitation. The limitation contained in this paragraph may not be waived and shall apply to a successor holder
of this Warrant.

 

    5

     

    

 

(ii) Principal
Market Regulation. The Company shall not issue any shares of Common Stock upon the exercise of this Warrant if the issuance
of such shares of Common Stock (taken together with the issuance of such shares upon the exercise of the SPA Warrants and the conversion
of the Notes or otherwise pursuant to the terms of the Notes or the SPA Warrants) would exceed the aggregate number of shares of
Common Stock which the Company may issue upon exercise or conversion or otherwise pursuant to the terms of the Notes or the SPA
Warrants (as the case may be) of the Warrants and the Notes without breaching the Company’s obligations under the rules or
regulations of the Principal Market (the number of shares which may be issued without violating such rules and regulations, the
“Exchange Cap”), except that such limitation shall not apply in the event that the Company (A) obtains the approval
of its stockholders as required by the applicable rules of the Principal Market for issuances of shares of Common Stock in excess
of such amount or (B) obtains a written opinion from outside counsel to the Company that such approval is not required, which opinion
shall be reasonably satisfactory to the Holder. Until such approval or such written opinion is obtained, no Buyer shall be issued
in the aggregate, upon conversion or exercise (as the case may be) of any Notes or any of the SPA Warrants or otherwise pursuant
to the terms of the Notes or the SPA Warrants, shares of Common Stock in an amount greater than the product of (i) the Exchange
Cap as of the Issuance Date multiplied by (ii) the quotient of (1) the original principal amount of Notes issued to such Buyer
pursuant to the Securities Purchase Agreement on the Closing Date (as defined in the Securities Purchase Agreement) divided by
(2) the aggregate original principal amount of all Notes issued to the Buyers pursuant to the Securities Purchase Agreement on
the Closing Date (with respect to each Buyer, the “Exchange Cap Allocation”). In the event that any Buyer shall
sell or otherwise transfer any of such Buyer’s SPA Warrants, the transferee shall be allocated a pro rata portion of such
Buyer’s Exchange Cap Allocation with respect to such portion of such SPA Warrants so transferred, and the restrictions of
the prior sentence shall apply to such transferee with respect to the portion of the Exchange Cap Allocation so allocated to such
transferee. Upon conversion and exercise in full of a holder’s Notes and SPA Warrants, the difference (if any) between such
holder’s Exchange Cap Allocation and the number of shares of Common Stock actually issued to such holder upon such holder’s
conversion in full of such Notes and such holder’s exercise in full of such SPA Warrants shall be allocated, to the respective
Exchange Cap Allocations of the remaining holders of Notes and related SPA Warrants on a pro rata basis in proportion to the shares
of Common Stock underlying the Notes and related SPA Warrants then held by each such holder of Notes and related SPA Warrants.
At any time after tenth (10th) Trading Day after the Stockholder Meeting Deadline (as defined in the Securities Purchase Agreement),
in the event that the Company is then prohibited from issuing any shares of Common Stock pursuant to this Section 1(f)(ii) (the
“Exchange Cap Shares”), in lieu of issuing and delivering such Exchange Cap Shares to the Holder, the Company
shall pay cash to the Holder in exchange for the cancellation of such portion of this Warrant exercisable into such Exchange Cap
Shares (the “Exchange Cap Payment Amount”) at a price equal to the sum of (x) the product of (A) such number
of Exchange Cap Shares and (B) the greatest Closing Sale Price of the Common Stock on any Trading Day during the period commencing
on the date the Holder delivers the applicable Exercise Notice with respect to such Exchange Cap Shares to the Company and ending
on the date of such payment under this Section 1(f)(ii) and (y) to the extent the Holder purchases (in an open market transaction
or otherwise) shares of Common Stock to deliver in satisfaction of a sale by the Holder of Exchange Cap Shares, any brokerage commissions
and other out-of-pocket expenses, if any, of the Holder incurred in connection therewith.

 

    6

     

    

 

(g) Reservation
of Shares.

 

(i) Required
Reserve Amount. So long as this Warrant remains outstanding, the Company shall at all times keep reserved for issuance under
this Warrant a number of shares of Common Stock at least equal to 200% of the maximum number of shares of Common Stock as shall
be necessary to satisfy the Company’s obligation to issue shares of Common Stock under the SPA Warrants then outstanding
(without regard to any limitations on exercise) (the “Required Reserve Amount”); provided that at no time shall
the number of shares of Common Stock reserved pursuant to this Section 1(g)(i) be reduced other than proportionally in connection
with any exercise or redemption of SPA Warrants or such other event covered by Section 2(a) below. The Required Reserve Amount
(including, without limitation, each increase in the number of shares so reserved) shall be allocated pro rata among the holders
of the SPA Warrants based on number of shares of Common Stock issuable upon exercise of SPA Warrants held by each holder on the
Closing Date (without regard to any limitations on exercise) or increase in the number of reserved shares, as the case may be (the
“Authorized Share Allocation”). In the event that a holder shall sell or otherwise transfer any of such holder’s
SPA Warrants, each transferee shall be allocated a pro rata portion of such holder’s Authorized Share Allocation. Any shares
of Common Stock reserved and allocated to any Person which ceases to hold any SPA Warrants shall be allocated to the remaining
holders of SPA Warrants, pro rata based on the number of shares of Common Stock issuable upon exercise of the SPA Warrants then
held by such holders (without regard to any limitations on exercise).

 

(ii) Insufficient
Authorized Shares. If, notwithstanding Section 1(g)(i) above, and not in limitation thereof, at any time while any of the SPA
Warrants remain outstanding, the Company does not have a sufficient number of authorized and unreserved shares of Common Stock
to satisfy its obligation to reserve the Required Reserve Amount (an “Authorized Share Failure”), then the Company
shall immediately take all action necessary to increase the Company’s authorized shares of Common Stock to an amount sufficient
to allow the Company to reserve the Required Reserve Amount for all the SPA Warrants then outstanding. Without limiting the generality
of the foregoing sentence, as soon as practicable after the date of the occurrence of an Authorized Share Failure, but in no event
later than sixty (60) days after the occurrence of such Authorized Share Failure, the Company shall hold a meeting of its stockholders
for the approval of an increase in the number of authorized shares of Common Stock. In connection with such meeting, the Company
shall provide each stockholder with a proxy statement and shall use its best efforts to solicit its stockholders’ approval
of such increase in authorized shares of Common Stock and to cause its board of directors to recommend to the stockholders that
they approve such proposal. In the event that the Company is prohibited from issuing shares of Common Stock upon an exercise of
this Warrant due to the failure by the Company to have sufficient shares of Common Stock available out of the authorized but unissued
shares of Common Stock (such unavailable number of shares of Common Stock, the “Authorization Failure Shares”),
in lieu of delivering such Authorization Failure Shares to the Holder, the Company shall pay cash in exchange for the cancellation
of such portion of this Warrant exercisable into such Authorization Failure Shares at a price equal to the sum of (i) the product
of (x) such number of Authorization Failure Shares and (y) the greatest Closing Sale Price of the Common Stock on any Trading Day
during the period commencing on the date the Holder delivers the applicable Exercise Notice with respect to such Authorization
Failure Shares to the Company and ending on the date of such issuance and payment under this Section 1(f); and (ii) to the extent
the Holder purchases (in an open market transaction or otherwise) shares of Common Stock to deliver in satisfaction of a sale by
the Holder of Authorization Failure Shares, any Buy-In Payment Amount, brokerage commissions and other out-of-pocket expenses,
if any, of the Holder incurred in connection therewith. Nothing contained in this Section 1(f) shall limit any obligations of the
Company under any provision of the Securities Purchase Agreement.

 

2. ADJUSTMENT OF
EXERCISE PRICE AND NUMBER OF WARRANT SHARES .The Exercise Price and number of Warrant
Shares issuable upon exercise of this Warrant are subject to adjustment from time to time as set forth in this Section 2.

 

(a) Stock
Dividends and Splits. Without limiting any provision of Section 3 or Section 4, if the Company, at any time on or after
the Subscription Date, (i) pays a stock dividend on one or more classes of its then outstanding shares of Common Stock or otherwise
makes a distribution on any class of capital stock that is payable in shares of Common Stock, (ii) subdivides (by any stock split,
stock dividend, recapitalization or otherwise) one or more classes of its then outstanding shares of Common Stock into a larger
number of shares or (iii) combines (by combination, reverse stock split or otherwise) one or more classes of its then outstanding
shares of Common Stock into a smaller number of shares, then in each such case the Exercise Price shall be multiplied by a fraction
of which the numerator shall be the number of shares of Common Stock outstanding immediately before such event and of which the
denominator shall be the number of shares of Common Stock outstanding immediately after such event. Any adjustment made pursuant
to clause (i) of this paragraph shall become effective immediately after the record date for the determination of stockholders
entitled to receive such dividend or distribution, and any adjustment pursuant to clause (ii) or (iii) of this paragraph shall
become effective immediately after the effective date of such subdivision or combination. If any event requiring an adjustment
under this paragraph occurs during the period that an Exercise Price is calculated hereunder, then the calculation of such Exercise
Price shall be adjusted appropriately to reflect such event.

 

    7

     

    

 

(b) Number
of Warrant Shares. Simultaneously with any adjustment to the Exercise Price pursuant to Section 2(a) above, the number
of Warrant Shares that may be purchased upon exercise of this Warrant shall be increased or decreased proportionately, so that
after such adjustment the aggregate Exercise Price payable hereunder for the adjusted number of Warrant Shares shall be the same
as the aggregate Exercise Price in effect immediately prior to such adjustment (without regard to any limitations on exercise contained
herein).

 

(c) Calculations.
All calculations under this Section 2 shall be made by rounding to the nearest cent or the nearest 1/100th of a
share, as applicable. The number of shares of Common Stock outstanding at any given time shall not include shares owned or held
by or for the account of the Company, and the disposition of any such shares shall be considered an issuance or sale of Common
Stock.

 

(d) Voluntary
Adjustment By Company. Subject to the rules and regulations of the Principal Market, the Company may at any time during the
term of this Warrant, with the prior written consent of the Required Holders (as defined in the Securities Purchase Agreement),
reduce the then current Exercise Price to any amount and for any period of time deemed appropriate by the board of directors of
the Company.

 

3.
RIGHTS UPON DISTRIBUTION OF ASSETS. In addition to any adjustments pursuant
to Section 2 above, 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, options, evidence of indebtedness or any other assets 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 or restrictions on exercise of this Warrant,
including without limitation, the Maximum Percentage) immediately before the date on 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 and the other Attribution Parties exceeding the Maximum Percentage, then the Holder
shall not be entitled to participate in such Distribution to the extent of the Maximum Percentage (and shall not be entitled to
beneficial ownership of such shares of Common Stock as a result of such Distribution (and beneficial ownership) to the extent
of any such excess) and the portion of such Distribution shall be held in abeyance for the benefit of the Holder until such time
or times, if ever, as its right thereto would not result in the Holder and the other Attribution Parties exceeding the Maximum
Percentage, at which time or times the Holder shall be granted such Distribution (and any Distributions declared or made on such
initial Distribution or on any subsequent Distribution held similarly in abeyance) to the same extent as if there had been no
such limitation).

 

    8

     

    

 

4. PURCHASE
RIGHTS; FUNDAMENTAL TRANSACTIONS.

 

(a) Purchase
Rights. In addition to any adjustments pursuant to Section 2 above, if at any time the Company grants, issues or sells
any Options, Convertible Securities or rights to purchase stock, warrants, securities or other property pro rata to the record
holders of any class 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
or restrictions on exercise of this Warrant, including without limitation, the Maximum Percentage) 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, issuance 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 and the other Attribution Parties exceeding the Maximum Percentage, then the Holder shall not be entitled
to participate in such Purchase Right to the extent of the Maximum Percentage (and shall not be entitled to beneficial ownership
of such shares of Common Stock as a result of such Purchase Right (and beneficial ownership) to the extent of any such excess)
and such Purchase Right to such extent shall be held in abeyance for the benefit of the Holder until such time or times, if ever,
as its right thereto would not result in the Holder and the other Attribution Parties exceeding the Maximum Percentage, at which
time or times the Holder shall be granted such right (and any Purchase Right granted, issued or sold on such initial Purchase Right
or on any subsequent Purchase Right held similarly in abeyance) to the same extent as if there had been no such limitation).

 

(b) Fundamental
Transactions. The Company shall not enter into or be party to a Fundamental Transaction unless (i)  the Successor Entity
assumes in writing all of the obligations of the Company under this Warrant and the other Transaction Documents (as defined in
the Securities Purchase Agreement) in accordance with the provisions of this Section 4(b) pursuant to written agreements in
form and substance satisfactory to the Holder and approved by the Holder prior to such Fundamental Transaction, including agreements
to 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, including, without limitation, which is exercisable for a corresponding number of
shares of capital stock 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 adjustments to the
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 (ii) the Successor Entity (including its Parent
Entity) is a publicly traded corporation whose common stock is quoted on or listed for trading on an Eligible Market. Upon the
consummation of each Fundamental Transaction, the Successor Entity shall succeed to, and be substituted for (so that from and after
the date of the applicable 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. Upon consummation of each Fundamental Transaction, the Successor
Entity shall deliver to the Holder confirmation that there shall be issued upon exercise of this Warrant at any time after the
consummation of the applicable Fundamental Transaction, in lieu of the shares of Common Stock (or other securities, cash, assets
or other property (except such items still issuable under Sections 3 and 4(a) above, which shall continue to be receivable
thereafter)) issuable upon the exercise of this Warrant prior to the applicable Fundamental Transaction, such shares of publicly
traded common stock (or its equivalent) of the Successor Entity (including its Parent Entity) which the Holder would have been
entitled to receive upon the happening of the applicable Fundamental Transaction had this Warrant been exercised immediately prior
to the applicable Fundamental Transaction (without regard to any limitations on the exercise of this Warrant), as adjusted in accordance
with the provisions of this Warrant. Notwithstanding the foregoing, and without limiting Section 1(f) hereof, the Holder may elect,
at its sole option, by delivery of written notice to the Company to waive this Section 4(b) to permit the Fundamental Transaction
without the assumption of this Warrant. In addition to and not in substitution for any other rights hereunder, prior to the consummation
of each Fundamental Transaction pursuant to which holders of shares of Common Stock are entitled to receive securities or other
assets with respect to or in exchange for shares of Common Stock (a “Corporate Event”), the Company shall make
appropriate provision to insure that the Holder will thereafter have the right to receive upon an exercise of this Warrant at any
time after the consummation of the applicable Fundamental Transaction but prior to the Expiration Date, in lieu of the shares of
the Common Stock (or other securities, cash, assets or other property (except such items still issuable under Sections 3 and
4(a) above, which shall continue to be receivable thereafter)) issuable upon the exercise of the Warrant prior to such Fundamental
Transaction, such shares of stock, securities, cash, assets or any other property whatsoever (including warrants or other purchase
or subscription rights) which the Holder would have been entitled to receive upon the happening of the applicable Fundamental Transaction
had this Warrant been exercised immediately prior to the applicable Fundamental Transaction (without regard to any limitations
on the exercise of this Warrant). Provision made pursuant to the preceding sentence shall be in a form and substance reasonably
satisfactory to the Holder.

 

    9

     

    

 

(c) Black
Scholes Value. Notwithstanding the foregoing and the provisions of Section 4(b) above, at the request of the Holder delivered
at any time commencing on the earliest to occur of (x) the public disclosure of any Change of Control, (y) the consummation of
any Change of Control and (z) the Holder first becoming aware of any Change of Control through the date that is thirty (30) days
after the public disclosure of the consummation of such Change of Control by the Company pursuant to a Current Report on Form 8-K
filed with the SEC, the Company or the Successor Entity (as the case may be) shall purchase this Warrant from the Holder on the
date of such request by paying to the Holder cash in an amount equal to the Black Scholes Value. Payment of such amounts shall
be made by the Company (or at the Company’s direction) to the Holder on or prior to the later of (x) the second (2nd)
Trading Day after the date of such request and (y) the date of consummation of such Change of Control.

 

(d) Application.
The provisions of this Section 4 shall apply similarly and equally to successive Fundamental Transactions and Corporate Events
and shall be applied as if this Warrant (and any such subsequent warrants) were fully exercisable and without regard to any limitations
on the exercise of this Warrant (provided that the Holder shall continue to be entitled to the benefit of the Maximum Percentage,
applied however with respect to shares of capital stock registered under the 1934 Act and thereafter receivable upon exercise of
this Warrant (or any such other warrant)).

 

5. NONCIRCUMVENTION.
The Company hereby covenants and agrees that the Company will not, by amendment of its Certificate of Incorporation (as
defined in the Securities Purchase Agreement), Bylaws (as defined in the Securities Purchase Agreement) or through any
reorganization, transfer of assets, consolidation, merger, scheme of arrangement, dissolution, issuance 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, and will at all times in good faith carry out all the provisions of this Warrant and take all action as may be
required to protect the rights of the Holder. Without limiting the generality of the foregoing, the Company (a) shall not
increase the par value of any shares of Common Stock receivable upon the exercise of this Warrant above the Exercise Price
then in effect, and (b) shall take all such actions as may be necessary or appropriate in order that the Company may validly
and legally issue fully paid and non-assessable shares of Common Stock upon the exercise of this Warrant. Notwithstanding
anything herein to the contrary, if after the sixty (60) calendar day anniversary of the Issuance Date, the Holder is not
permitted to exercise this Warrant in full for any reason (other than pursuant to restrictions set forth in Section 1(f)
hereof), the Company shall use its best efforts to promptly remedy such failure, including, without limitation, obtaining
such consents or approvals as necessary to permit such exercise into shares of Common Stock.

 

6.
WARRANT HOLDER NOT DEEMED A STOCKHOLDER. Except as otherwise specifically provided herein, the Holder, solely in its capacity
as a holder of this Warrant, shall not be entitled to vote or receive dividends or be deemed the holder of share capital of the
Company for any purpose, nor shall anything contained in this Warrant be construed to confer upon the Holder, solely in its capacity
as the Holder of this Warrant, any of the rights of a stockholder of the Company or any right to vote, give or withhold consent
to any corporate action (whether any reorganization, issue of stock, reclassification of stock, consolidation, merger, conveyance
or otherwise), receive notice of meetings, receive dividends or subscription rights, or otherwise, prior to the issuance to the
Holder of the Warrant Shares which it is then entitled to receive upon the due exercise of this Warrant. In addition, nothing
contained in this Warrant shall be construed as imposing any liabilities on the Holder to purchase any securities (upon exercise
of this Warrant or otherwise) or as a stockholder of the Company, whether such liabilities are asserted by the Company or by creditors
of the Company. Notwithstanding this Section 6, the Company shall provide the Holder with copies of the same notices and
other information given to the stockholders of the Company generally, contemporaneously with the giving thereof to the stockholders.

7. REISSUANCE

if less than the total number of Warrant Shares then underlying this Warrant is being transferred, a new Warrant (in accordance
with Section 7(d)) to the Holder representing the right to purchase the number of Warrant Shares not being transferred.

 

(b) Lost,
Stolen or Mutilated Warrant. Upon receipt by the Company of evidence reasonably satisfactory to the Company of the loss, theft,
destruction or mutilation of this Warrant (as to which a written certification and the indemnification contemplated below shall
suffice as such evidence), and, in the case of loss, theft or destruction, of any indemnification undertaking by the Holder to
the Company in customary and reasonable form and, in the case of mutilation, upon surrender and cancellation of this Warrant, the
Company shall execute and deliver to the Holder a new Warrant (in accordance with Section 7(d)) representing the right to
purchase the Warrant Shares then underlying this Warrant.

 

(c) Exchangeable
for Multiple Warrants. This Warrant is exchangeable, upon the surrender hereof by the Holder at the principal office of the
Company, for a new Warrant or Warrants (in accordance with Section 7(d)) representing in the aggregate the right to purchase
the number of Warrant Shares then underlying this Warrant, and each such new Warrant will represent the right to purchase such
portion of such Warrant Shares as is designated by the Holder at the time of such surrender; provided, however, no warrants for
fractional shares of Common Stock shall be given.

 

(d) Issuance
of New Warrants. Whenever the Company is required to issue a new Warrant pursuant to the terms of this Warrant, such new Warrant
(i) shall be of like tenor with this Warrant, (ii) shall represent, as indicated on the face of such new Warrant, the right to

the other new Warrants issued in connection with such issuance, does not exceed the number of Warrant Shares then underlying this
Warrant), (iii) shall have an issuance date, as indicated on the face of such new Warrant which is the same as the Issuance Date,
and (iv) shall have the same rights and conditions as this Warrant.

 

8.
NOTICES. Whenever notice is required to be given under this Warrant, unless
otherwise provided herein, such notice shall be given in accordance with Section 9(f) of the Securities Purchase Agreement.
The Company shall provide the Holder with prompt written notice of all actions taken pursuant to this Warrant (other than the
issuance of shares of Common Stock upon exercise in accordance with the terms hereof), including in reasonable detail a description
of such action and the reason therefor. Without limiting the generality of the foregoing, the Company will give written notice
to the Holder (i) immediately upon each adjustment of the Exercise Price and the number of Warrant Shares, setting forth in reasonable
detail, and certifying, the calculation of such adjustment(s), (ii) at least fifteen (15) days prior to the date on which the
Company closes its books or takes a record with respect to any dividend or distribution upon the shares of Common Stock or (C)

that such information shall be made known to the public prior to or in conjunction with such notice being provided to the Holder,
and (iii) at least ten (10) Trading Days prior to the consummation of any Fundamental Transaction. To the extent that any notice
provided hereunder constitutes, or contains, material, non-public information regarding the Company or any of its Subsidiaries,
the Company shall simultaneously file such notice with the SEC (as defined in the Securities Purchase Agreement) pursuant to a
Current Report on Form 8-K. If the Company or any of its Subsidiaries provides material non-public information to the Holder that
is not simultaneously filed in a Current Report on Form 8-K and the Holder has not agreed to receive such material non-public
information, the Company hereby covenants and agrees that the Holder shall not have any duty of confidentiality to the Company,
any of its Subsidiaries or any of their respective officers, directors, employees, affiliates or agents with respect to, or a
duty to any of the foregoing not to trade on the basis of, such material non-public information. It is expressly understood and
agreed that the time of execution specified by the Holder in each Exercise Notice shall be definitive and may not be disputed
or challenged by the Company.

 

9.
DISCLOSURE. Upon delivery by the Company to the Holder (or receipt by the Company from
the Holder) of any notice in accordance with the terms of this Warrant, unless the Company has in good faith determined that the
matters relating to such notice do not constitute material, non-public information relating to the Company or any of its Subsidiaries,
the Company shall on or prior to 9:00 am, New York city time on the Business Day immediately following such notice delivery date,
publicly disclose such material, non-public information on a Current Report on Form 8-K or otherwise. In the event that the Company
believes that a notice contains material, non-public information relating to the Company or any of its Subsidiaries, the Company
so shall indicate to the Holder explicitly in writing in such notice (or immediately upon receipt of notice from the Holder, as
applicable), and in the absence of any such written indication in such notice (or notification from the Company immediately upon
receipt of notice from the Holder), the Holder shall be entitled to presume that information contained in the notice does not
constitute material, non-public information relating to the Company or any of its Subsidiaries. Nothing contained in this Section
9 shall limit any obligations of the Company, or any rights of the Holder, under Section 4(i) of the Securities Purchase Agreement.

 

10. ABSENCE
OF TRADING AND DISCLOSURE RESTRICTIONS. The Company acknowledges and agrees that the Holder is not a fiduciary or agent of
the Company and that the Holder shall have no obligation to (a) maintain the confidentiality of any information provided by the
Company or (b) refrain from trading any securities while in possession of such information in the absence of a written non-disclosure
agreement signed by an officer of the Holder that explicitly provides for such confidentiality and trading restrictions. In the
absence of such an executed, written non-disclosure agreement, the Company acknowledges that the Holder may freely trade in any
securities issued by the Company, may possess and use any information provided by the Company in connection with such trading activity,
and may disclose any such information to any third party.

 

    11

     

    

 

11. AMENDMENT
AND WAIVER. Except as otherwise provided herein, the provisions of this Warrant (other than Section 1(f)) may be
amended and the Company may take any action herein prohibited, or omit to perform any act herein required to be performed by
it, only if the Company has obtained the written consent of the Holder. No waiver shall be effective unless it is in writing
and signed by an authorized representative of the waiving party.

 

12. SEVERABILITY.
If any provision of this Warrant is prohibited by law or otherwise determined to be invalid or unenforceable by a court of competent
jurisdiction, the provision that would otherwise be prohibited, invalid or unenforceable shall be deemed amended to apply to the
broadest extent that it would be valid and enforceable, and the invalidity or unenforceability of such provision shall not affect
the validity of the remaining provisions of this Warrant so long as this Warrant as so modified continues to express, without
material change, the original intentions of the parties as to the subject matter hereof and the prohibited nature, invalidity
or unenforceability of the provision(s) in question does not substantially impair the respective expectations or reciprocal obligations
of the parties or the practical realization of the benefits that would otherwise be conferred upon the parties. The parties will
endeavor in good faith negotiations to replace the prohibited, invalid or unenforceable provision(s) with a valid provision(s),
the effect of which comes as close as possible to that of the prohibited, invalid or unenforceable provision(s).

 

13.
GOVERNING LAW. This Warrant shall be governed by and construed and enforced in
accordance with, and all questions concerning the construction, validity, interpretation and performance of this Warrant shall
be governed by, the internal laws of the State of New York, without giving effect to any choice of law or conflict of law provision
or rule (whether of the State of New York or any other jurisdictions) that would cause the application of the laws of any jurisdictions
other than the State of New York. The Company hereby irrevocably waives personal service of process and consents to process being
served in any such suit, action or proceeding by mailing a copy thereof to the Company at the address set forth in Section 9(f)
of the Securities Purchase Agreement and agrees that such service shall constitute good and sufficient service of process and
notice thereof. The Company hereby irrevocably submits to the exclusive jurisdiction of the state and federal courts sitting in
The City of New York, Borough of Manhattan, for the adjudication of any dispute hereunder or in connection herewith or with any
transaction contemplated hereby or discussed herein, and hereby irrevocably waives, and agrees not to assert in any suit, action
or proceeding, any claim that it is not personally subject to the jurisdiction of any such court, that such suit, action or proceeding
is brought in an inconvenient forum or that the venue of such suit, action or proceeding is improper. Nothing contained herein
shall be deemed to limit in any way any right to serve process in any manner permitted by law. Nothing contained herein shall
be deemed or operate to preclude the Holder from bringing suit or taking other legal action against the Company in any other jurisdiction
to collect on the Company’s obligations to the Holder, to realize on any collateral or any other security for such obligations,
or to enforce a judgment or other court ruling in favor of the Holder. THE COMPANY HEREBY IRREVOCABLY WAIVES ANY RIGHT IT MAY
HAVE TO, AND AGREES NOT TO REQUEST, A JURY TRIAL FOR THE ADJUDICATION OF ANY DISPUTE HEREUNDER OR IN CONNECTION WITH OR ARISING
OUT OF THIS WARRANT OR ANY TRANSACTION CONTEMPLATED HEREBY.

 

14.
CONSTRUCTION; HEADINGS. This Warrant shall be deemed to be jointly drafted by
the Company and the Holder and shall not be construed against any Person as the drafter hereof. The headings of this Warrant are
for convenience of reference and shall not form part of, or affect the interpretation of, this Warrant. Terms used in this Warrant
but defined in the other Transaction Documents shall have the meanings ascribed to such terms on the Closing Date (as defined
in the Securities Purchase Agreement) in such other Transaction Documents unless otherwise consented to in writing by the Holder.

 

15.
DISPUTE RESOLUTION .

(i) In
the case of a dispute relating to the Exercise Price, the Closing Sale Price, the Bid Price, Black Scholes Value or fair market
value or the arithmetic calculation of the number of Warrant Shares (as the case may be) (including, without limitation, a dispute
relating to the determination of any of the foregoing), the Company or the Holder (as the case may be) shall submit the dispute
to the other party via facsimile (A) if by the Company, within two (2) Business Days after the occurrence of the circumstances
giving rise to such dispute or (B) if by the Holder, at any time after the Holder learned of the circumstances giving rise to such
dispute. If the Holder and the Company are unable to promptly resolve such dispute relating to such Exercise Price, such Closing
Sale Price, such Bid Price, Black Scholes Value or such fair market value or such arithmetic calculation of the number of Warrant
Shares (as the case may be), at any time after the second (2nd) Business Day following such initial notice by the Company
or the Holder (as the case may be) of such dispute to the Company or the Holder (as the case may be), then the Holder may, at its
sole option, select an independent, reputable investment bank to resolve such dispute.

 

(ii) The
Holder and the Company shall each deliver to such investment bank (A) a copy of the initial dispute submission so delivered in
accordance with the first sentence of this Section 15 and (B) written documentation supporting its position with respect to such
dispute, in each case, no later than 5:00 p.m. (New York time) by the fifth (5th) Business Day immediately following
the date on which the Holder selected such investment bank (the “Dispute Submission Deadline”) (the documents
referred to in the immediately preceding clauses (A) and (B) are collectively referred to herein as the “Required Dispute
Documentation”) (it being understood and agreed that if either the Holder or the Company fails to so deliver all of the
Required Dispute Documentation by the Dispute Submission Deadline, then the party who fails to so submit all of the Required Dispute
Documentation shall no longer be entitled to (and hereby waives its right to) deliver or submit any written documentation or other
support to such investment bank with respect to such dispute and such investment bank shall resolve such dispute based solely on
the Required Dispute Documentation that was delivered to such investment bank prior to the Dispute Submission Deadline). Unless
otherwise agreed to in writing by both the Company and the Holder or otherwise requested by such investment bank, neither the Company
nor the Holder shall be entitled to deliver or submit any written documentation or other support to such investment bank in connection
with such dispute (other than the Required Dispute Documentation).

Company and the Holder shall cause such investment bank to determine the resolution of such dispute and notify the Company and
the Holder of such resolution no later than ten (10) Business Days immediately following the Dispute Submission Deadline. The fees
and expenses of such investment bank shall be borne solely by the Company, and such investment bank’s resolution of such
dispute shall be final and binding upon all parties absent manifest error.

 

(b) Miscellaneous.
The Company expressly acknowledges and agrees that (i) this Section 15 constitutes an agreement to arbitrate between the Company
and the Holder (and constitutes an arbitration agreement) under the rules then in effect under § 7501, et seq. of the New
York Civil Practice Law and Rules (“CPLR”) and that the Holder is authorized to apply for an order to compel
arbitration pursuant to CPLR § 7503(a) in order to compel compliance with this Section 15, (ii) the terms of this Warrant
and each other applicable Transaction Document shall serve as the basis for the selected investment bank’s resolution of
the applicable dispute, such investment bank shall be entitled (and is hereby expressly authorized) to make all findings, determinations
and the like that such investment bank determines are required to be made by such investment bank in connection with its resolution
of such dispute and in resolving such dispute such investment bank shall apply such findings, determinations and the like to the
terms of this Warrant and any other applicable Transaction Documents, (iii) the Holder (and only the Holder), in its sole discretion,
shall have the right to submit any dispute described in this Section 15 to any state or federal court sitting in The City of New
York, Borough of Manhattan in lieu of utilizing the procedures set forth in this Section 15 and (iv) nothing in this Section 15
shall limit the Holder from obtaining any injunctive relief or other equitable remedies (including, without limitation, with respect
to any matters described in this Section 15).

 

16.
REMEDIES, CHARACTERIZATION, OTHER OBLIGATIONS, BREACHES AND INJUNCTIVE RELIEF.
The remedies provided in this Warrant shall be cumulative and in addition to all other remedies available under this Warrant and
the other Transaction Documents, at law or in equity (including a decree of specific performance and/or other injunctive relief),
and nothing herein shall limit the right of the Holder to pursue actual and consequential damages for any failure by the Company
to comply with the terms of this Warrant. The Company covenants to the Holder that there shall be no characterization concerning
this instrument other than as expressly provided herein. Amounts set forth or provided for herein with respect to payments, exercises
and the like (and the computation thereof) shall be the amounts to be received by the Holder and shall not, except as expressly
provided herein, be subject to any other obligation of the Company (or the performance thereof). The Company acknowledges that
a breach by it of its obligations hereunder will cause irreparable harm to the Holder and that the remedy at law for any such
breach may be inadequate. The Company therefore agrees that, in the event of any such breach or threatened breach, the holder
of this Warrant shall be entitled, in addition to all other available remedies, to specific performance and/or temporary, preliminary
and permanent injunctive or other equitable relief from any court of competent jurisdiction in any such case without the necessity
of proving actual damages and without posting a bond or other security. The Company shall provide all information and documentation
to the Holder that is requested by the Holder to enable the Holder to confirm the Company’s compliance with the terms and
conditions of this Warrant (including, without limitation, compliance with Section 2 hereof). The issuance of shares and
certificates for shares as contemplated hereby upon the exercise of this Warrant shall be made without charge to the Holder or
such shares for any issuance tax or other costs in respect thereof, provided that the Company shall not be required to pay any
tax which may be payable in respect of any transfer involved in the issuance and delivery of any certificate in a name other than
the Holder or its agent on its behalf.

can be sold, assigned or transferred pursuant to Rule 144 or Rule 144A promulgated under the 1933 Act (or a successor rule thereto)
(collectively, “Rule 144”); (ii) any sale of the Securities made in reliance on Rule 144 may be made only in
accordance with the terms of Rule 144, and further, if Rule 144 is not applicable, any resale of the Securities under circumstances
in which the seller (or the Person through whom the sale is made) may be deemed to be an underwriter (as that term is defined
in the 1933 Act) may require compliance with some other exemption under the 1933 Act or the rules and regulations of the SEC promulgated
thereunder; and (iii) except as required by the Registration Rights Agreement, neither the Company nor any other Person is under
any obligation to register the Securities under the 1933 Act or any state securities laws or to comply with the terms and conditions
of any exemption thereunder. Notwithstanding the foregoing, the Securities may be pledged in connection with a bona fide margin
account or other loan or financing arrangement secured by the Securities and such pledge of Securities shall not be deemed to
be a transfer, sale or assignment of the Securities hereunder, and no Buyer effecting a pledge of Securities shall be required
to provide the Company with any notice thereof or otherwise make any delivery to the Company pursuant to this Agreement or any
other Transaction Document (as defined in Section 3(b)), including, without limitation, this Section 2(g).

 

(h) Validity;
Enforcement. This Agreement and the Registration Rights Agreement have been duly
and validly authorized, executed and delivered on behalf of such Buyer and shall constitute the legal, valid and binding obligations
of such Buyer enforceable against such Buyer in accordance with their respective terms, except as such enforceability may be limited
by general principles of equity or to applicable bankruptcy, insolvency, reorganization, moratorium, liquidation and other similar
laws relating to, or affecting generally, the enforcement of applicable creditors’ rights and remedies.

or instrument to which such Buyer is a party, or (iii) result in a violation of any law, rule, regulation, order, judgment or
decree (including federal and state securities laws) applicable to such Buyer, except in the case of clauses (ii) and (iii) above,

3. REPRESENTATIONS
AND WARRANTIES OF THE COMPANY.

 

The Company represents
and warrants to each of the Buyers that, as of the date hereof and as of the Closing Date:

 

(a) Organization
and Qualification. Each of the Company and each of its Subsidiaries are entities
duly organized and validly existing and in good standing under the laws of the jurisdiction in which they are formed, and have
the requisite power and authority to own their properties and to carry on their business as now being conducted and as presently
proposed to be conducted. Each of the Company and each of its Subsidiaries is duly qualified as a foreign entity to do business
and is in good standing in every jurisdiction in which its ownership of property or the nature of the business conducted by it
makes such qualification necessary, except to the extent that the failure to be so qualified or be in good standing would not
reasonably be expected to have a Material Adverse Effect (as defined below). As used in this Agreement, “Material Adverse
Effect” means any material adverse effect on (i) the business, properties, assets, liabilities, operations (including
results thereof), condition (financial or otherwise) or prospects of the Company or any Subsidiary, individually or taken as a
whole, (ii) the transactions contemplated hereby or in any of the other Transaction Documents or any other agreements or instruments
to be entered into in connection herewith or therewith or (iii) the authority or ability of the Company or any of its Subsidiaries
to perform any of their respective obligations under any of the Transaction Documents (as defined below). Other than the Persons
(as defined below) set forth on Schedule 3(a), the Company has no Subsidiaries. “Subsidiaries”
means any Person in which the Company, directly or indirectly, (I) owns any of the outstanding capital stock or holds any equity
or similar interest of such Person or (II) controls or operates all or any part of the business, operations or administration
of such Person, and each of the foregoing, is individually referred to herein as a “Subsidiary.”

(b) Authorization;
Enforcement; Validity. The Company has the requisite power and authority to enter
into and perform its obligations under this Agreement and the other Transaction Documents and to issue the Securities in accordance

of the Notes and the reservation for issuance and issuance of the Conversion Shares issuable upon conversion of the Notes and
the issuance of the Warrants and the reservation for issuance and issuance of the Warrant Shares issuable upon exercise of the
Warrants) have been duly authorized by the Company’s board of directors and (other than the filing with the SEC of one or
more Registration Statements in accordance with the requirements of the Registration Rights Agreement, a Form D with the SEC and
any other filings as may be required by any state securities agencies) no further filing, consent or authorization is required
by the Company, its Subsidiaries, their respective boards of directors or their stockholders or other governing body. This Agreement
has been, and the other Transaction Documents to which it is a party will be prior to the Closing, duly executed and delivered
by the Company, and each constitutes the legal, valid and binding obligations of the Company, enforceable against the Company
in accordance with its respective terms, except as such enforceability may be limited by general principles of equity or applicable
bankruptcy, insolvency, reorganization, moratorium, liquidation or similar laws relating to, or affecting generally, the enforcement
of applicable creditors’ rights and remedies and except as rights to indemnification and to contribution may be limited
by federal or state securities law. “Transaction Documents” means, collectively, this Agreement, the Notes,
the Warrants, the Registration Rights Agreement, the Irrevocable Transfer Agent Instructions (as defined below) and each of the
other agreements and instruments entered into or delivered by any of the parties hereto in connection with the transactions contemplated
hereby and thereby, as may be amended from time to time.

 

(c) Issuance
of Securities. The issuance of the Notes and the Warrants are duly authorized and upon issuance in accordance with the terms
of the Transaction Documents shall be validly issued, fully paid and non-assessable and free from all preemptive or similar rights,
mortgages, defects, claims, liens, pledges, charges, taxes, rights of first refusal, encumbrances, security interests and other
encumbrances (collectively “Liens”) with respect to the issuance thereof. As of the Closing, the Company shall
have reserved from its duly authorized capital stock not less than 200% of the sum of (i) the maximum number of Conversion Shares
issuable upon conversion of the Notes (assuming for purposes hereof that (x) the Notes are convertible at the at the Alternate
Conversion Price (as defined in the Notes) assuming an Alternate Conversion Date (as defined in the Notes) as of the Closing Date
and (y) any such conversion shall not take into account any limitations on the conversion of the Notes set forth in the Notes),
and (ii) the maximum number of Warrant Shares initially issuable upon exercise of the Warrants (without taking into account any
limitations on the exercise of the Warrants set forth therein). Upon issuance or conversion in accordance with the Notes or exercise
in accordance with the Warrants (as the case may be), the Conversion Shares and the Warrant Shares, respectively, when issued,
will be validly issued, fully paid and nonassessable and free from all preemptive or similar rights or Liens with respect to the
issue thereof, with the holders being entitled to all rights accorded to a holder of Common Stock. Subject to the accuracy of the
representations and warranties of the Buyers in this Agreement, the offer and issuance by the Company of the Securities is exempt
from registration under the 1933 Act.

(d) No Conflicts.
The execution, delivery and performance of the Transaction Documents by the Company and the consummation by the Company of the
transactions contemplated hereby and thereby (including, without limitation, the issuance of the Notes, the Warrants, the Conversion
Shares and the Warrant Shares and the reservation for issuance of the Conversion Shares and the Warrant Shares) will not (i) result
in a violation of the Certificate of Incorporation (as defined below) (including, without limitation, any certificate of designation
contained therein), Bylaws (as defined below), certificate of formation, memorandum of association, articles of association, bylaws
or other organizational documents of the Company or any of its Subsidiaries, or any capital stock or other securities of the Company
or any of its Subsidiaries, (ii) conflict with, or constitute a default (or an event which with notice or lapse of time or both
would become a default) in any respect under, or give to others any rights of termination, amendment, acceleration or cancellation
of, any agreement, indenture or instrument to which the Company or any of its Subsidiaries is a party, or (iii) result in a violation
of any law, rule, regulation, order, judgment or decree (including, without limitation, federal and state securities laws and

all applicable federal and state laws, rules and regulations) applicable to the Company or any of its Subsidiaries or by which
any property or asset of the Company or any of its Subsidiaries is bound or affected.

registration with (other than the filing with the SEC of one or more Registration Statements in accordance with the requirements
of the Registration Rights Agreement, a Form D with the SEC and any other filings as may be required by any state securities agencies),
any Governmental Entity (as defined below) or any regulatory or self-regulatory agency or any other Person in order for it to
execute, deliver or perform any of its respective obligations under or contemplated by the Transaction Documents, in each case,
in accordance with the terms hereof or thereof. All consents, authorizations, orders, filings and registrations which the Company
or any Subsidiary is required to obtain pursuant to the preceding sentence have been or will be obtained or effected on or prior
to the Closing Date, and neither the Company nor any of its Subsidiaries are aware of any facts or circumstances which might prevent
the Company or any of its Subsidiaries from obtaining or effecting any of the registration, application or filings contemplated
by the Transaction Documents. The Company is not in violation of the requirements of the Principal Market and has no knowledge
of any facts or circumstances which could reasonably lead to delisting or suspension of the Common Stock in the foreseeable future.

(f) Acknowledgment
Regarding Buyer’s Purchase of Securities. The Company acknowledges and agrees
that each Buyer is acting solely in the capacity of an arm’s length purchaser with respect to the Transaction Documents
and the transactions contemplated hereby and thereby and that no Buyer is (i) an officer or director of the Company or any of
its Subsidiaries, (ii) an “affiliate” (as defined in Rule 144) of the Company or any of its Subsidiaries or (iii)
to its knowledge, a “beneficial owner” of more than 10% of the shares of Common Stock (as defined for purposes of
Rule 13d-3 of the Securities Exchange Act of 1934, as amended (the “1934 Act”)). The Company further acknowledges
that no Buyer is acting as a financial advisor or fiduciary of the Company or any of its Subsidiaries (or in any similar capacity)
with respect to the Transaction Documents and the transactions contemplated hereby and thereby, and any advice given by a Buyer
or any of its representatives or agents in connection with the Transaction Documents and the transactions contemplated hereby
and thereby is merely incidental to such Buyer’s purchase of the Securities. The Company further represents to each Buyer
that the Company’s and each Subsidiary’s decision to enter into the Transaction Documents to which it is a party has
been based solely on the independent evaluation by the Company, each Subsidiary and their respective representatives.

 

(g) No General
Solicitation; Placement Agent’s Fees. Neither the Company, nor any of its
Subsidiaries or affiliates, nor any Person acting on its or their behalf, has engaged in any form of general solicitation or general
advertising (within the meaning of Regulation D) in connection with the offer or sale of the Securities. The Company shall be
responsible for the payment of any placement agent’s fees, financial advisory fees, or brokers’ commissions (other
than for Persons engaged by any Buyer or its investment advisor) relating to or arising out of the transactions contemplated hereby,
including, without limitation, placement agent fees payable to Dawson James Securities, Inc., as placement agent (the “Placement
Agent”) in connection with the sale of the Securities. The fees and expenses of the Placement Agent to be paid by the
Company or any of its Subsidiaries are as set forth on Schedule 3(g) attached hereto. The Company shall pay, and hold each Buyer
harmless against, any liability, loss or expense (including, without limitation, attorney’s fees and out-of-pocket expenses)
arising in connection with any such claim. The Company acknowledges that it has engaged the Placement Agent in connection with
the sale of the Securities. Other than the Placement Agent, neither the Company nor any of its Subsidiaries has engaged any placement
agent or other agent in connection with the offer or sale of the Securities.

 

(h) No Integrated
Offering. None of the Company, its Subsidiaries or any of their affiliates, nor
any Person acting on 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 require registration of the issuance of any of the Securities under the 1933
Act, whether through integration with prior offerings or otherwise, or cause this offering of the Securities to require approval
of stockholders of the Company for purposes of the 1933 Act or under any applicable stockholder approval provisions, including,
without limitation, under the rules and regulations of any exchange or automated quotation system on which any of the securities
of the Company are listed or designated for quotation. None of the Company, its Subsidiaries, their affiliates nor any Person
acting on their behalf will take any action or steps that would require registration of the issuance of any of the Securities
under the 1933 Act or cause the offering of any of the Securities to be integrated with other offerings of securities of the Company.

 

(i) Dilutive
Effect. The Company understands and acknowledges that the number of Conversion
Shares and Warrant Shares will increase in certain circumstances. The Company further acknowledges that its obligation to issue
the Conversion Shares pursuant to the terms of the Notes in accordance with this Agreement and the Notes and the Warrant Shares
upon exercise of the Warrants in accordance with this Agreement, the Notes and the Warrants is, in each case, absolute and unconditional
regardless of the dilutive effect that such issuance may have on the ownership interests of other stockholders of the Company.

(j) Application
of Takeover Protections; Rights Agreement. Except for the items set forth on Schedule
3(j), the Company and its board of directors have taken all necessary action, if any, in order to render inapplicable any
control share acquisition, interested stockholder, business combination, poison pill (including, without limitation, any distribution
under a rights agreement), stockholder rights plan or other similar anti-takeover provision under the Certificate of Incorporation,
Bylaws or other organizational documents or the laws of the jurisdiction of its incorporation or otherwise which is or could become
applicable to any Buyer as a result of the transactions contemplated by this Agreement, including, without limitation, the Company’s
issuance of the Securities and any Buyer’s ownership of the Securities. The Company and its board of directors have taken
all necessary action, if any, in order to render inapplicable any stockholder rights plan or similar arrangement relating to accumulations
of beneficial ownership of shares of Common Stock or a change in control of the Company or any of its Subsidiaries.

 

(k) SEC Documents;
Financial Statements. Since June 29, 2020 (the date of effectiveness of the Company’s
registration statement on Form S-1 in connection with the Company’s initial public offering), the Company has filed all
reports, schedules, forms, proxy statements, statements and other documents required to be filed by it with the SEC pursuant to
the reporting requirements of the 1934 Act (all of the foregoing filed prior to the date hereof and all exhibits and appendices
included therein and financial statements, notes and schedules thereto and documents incorporated by reference therein being hereinafter
referred to as the “SEC Documents”). The Company has delivered or has made available to the Buyers or their
respective representatives true, correct and complete copies of each of the SEC Documents not available on the EDGAR system. As
of their respective dates, the SEC Documents complied in all material respects with the requirements of the 1934 Act and the rules
and regulations of the SEC promulgated thereunder applicable to the SEC Documents, and none of the SEC Documents, at the time
they were filed with the SEC, contained any untrue statement of a material fact or omitted 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, not misleading. As of their respective dates, the financial statements of the Company included in the SEC Documents complied
in all material respects with applicable accounting requirements and the published rules and regulations of the SEC with respect
thereto as in effect as of the time of filing. Such financial statements have been prepared in accordance with generally accepted
accounting principles (“GAAP”), consistently applied, during the periods involved (except (i) as may be otherwise
indicated in such financial statements or the notes thereto, or (ii) in the case of unaudited interim statements, to the extent
they may exclude footnotes or may be condensed or summary statements) and fairly present in all material respects the financial
position of the Company as of the dates thereof and the results of its operations and cash flows for the periods then ended (subject,
in the case of unaudited statements, to normal year-end audit adjustments which will not be material, either individually or in
the aggregate). The reserves, if any, established by the Company or the lack of reserves, if applicable, are reasonable based
upon facts and circumstances known by the Company on the date hereof and there are no loss contingencies that are required to
be accrued by the Statement of Financial Accounting Standard No. 5 of the Financial Accounting Standards Board which are not provided
for by the Company in its financial statements or otherwise. No other information provided by or on behalf of the Company to any
of the Buyers which is not included in the SEC Documents (including, without limitation, information referred to in Section 2(e)
of this Agreement or in the disclosure schedules to this Agreement) contains any untrue statement of a material fact or omits
to state any material fact necessary in order to make the statements therein not misleading, in the light of the circumstance
under which they are or were made. The Company is not currently contemplating to amend or restate any of the financial statements
(including, without limitation, any notes or any letter of the independent accountants of the Company with respect thereto) included
in the SEC Documents (the “Financial Statements”), nor is the Company currently aware of facts or circumstances
which would require the Company to amend or restate any of the Financial Statements, in each case, in order for any of the Financials
Statements to be in compliance with GAAP and the rules and regulations of the SEC. The Company has not been informed by its independent
accountants that they recommend that the Company amend or restate any of the Financial Statements or that there is any need for
the Company to amend or restate any of the Financial Statements.

(l) Absence
of Certain Changes. Since the date of the Company’s most recent audited financial
statements contained in its Prospectus, dated September 1, 2020, filed pursuant to Rule 424(b) under the 1933 Act (the “Prospectus”),
there has been no material adverse change and no material adverse development in the business, assets, liabilities, properties,
operations (including results thereof), condition (financial or otherwise) or prospects of the Company or any of its Subsidiaries.
Since the date of the Company’s most recent audited financial statements contained in the Prospectus, neither the Company
nor any of its Subsidiaries has (i) declared or paid any dividends, (ii) sold any assets, individually or in the aggregate, outside
of the ordinary course of business or (iii) made any capital expenditures, individually or in the aggregate, outside of the ordinary
course of business. Neither the Company nor any of its Subsidiaries has taken any steps to seek protection pursuant to any law
or statute relating to bankruptcy, insolvency, reorganization, receivership, liquidation or winding up, nor does the Company or
any Subsidiary have any knowledge or reason to believe that any of their respective creditors intend to initiate involuntary bankruptcy
proceedings or any actual knowledge of any fact which would reasonably lead a creditor to do so. The Company and its Subsidiaries,
individually and on a consolidated basis, are not as of the date hereof, and after giving effect to the transactions contemplated
hereby to occur at the Closing, will not be Insolvent (as defined below). For purposes of this Section 3(l), “Insolvent”
means, (i) with respect to the Company and its Subsidiaries, on a consolidated basis, (A) the present fair saleable value of the
Company’s and its Subsidiaries’ assets is less than the amount required to pay the Company’s and its Subsidiaries’
total Indebtedness (as defined below), (B) the Company and its Subsidiaries are unable to pay their debts and liabilities, subordinated,
contingent or otherwise, as such debts and liabilities become absolute and matured or (C) the Company and its Subsidiaries intend
to incur or believe that they will incur debts that would be beyond their ability to pay as such debts mature; and (ii) with respect
to the Company and each Subsidiary, individually, (A) the present fair saleable value of the Company’s or such Subsidiary’s
(as the case may be) assets is less than the amount required to pay its respective total Indebtedness, (B) the Company or such
Subsidiary (as the case may be) is unable to pay its respective debts and liabilities, subordinated, contingent or otherwise,
as such debts and liabilities become absolute and matured or (C) the Company or such Subsidiary (as the case may be) intends to
incur or believes that it will incur debts that would be beyond its respective ability to pay as such debts mature. Neither the
Company nor any of its Subsidiaries has engaged in any business or in any transaction, and is not about to engage in any business
or in any transaction, for which the Company’s or such Subsidiary’s remaining assets constitute unreasonably small
capital with which to conduct the business in which it is engaged as such business is now conducted and is proposed to be conducted.

 

(m) No Undisclosed
Events, Liabilities, Developments or Circumstances. No event, liability, development
or circumstance has occurred or exists, or is reasonably expected to exist or occur with respect to the Company, any of its Subsidiaries
or any of their respective businesses, properties, liabilities, prospects, operations (including results thereof) or condition
(financial or otherwise), that (i) would be required to be disclosed by the Company under applicable securities laws on a registration
statement on Form S-1 filed with the SEC relating to an issuance and sale by the Company of its Common Stock and which has not
been publicly announced, (ii) could have a material adverse effect on any Buyer’s investment hereunder or (iii) could have
a Material Adverse Effect.

 

(n) Conduct
of Business; Regulatory Permits. Neither the Company nor any of its Subsidiaries
is in violation of any term of or in default under its Certificate of Incorporation, any certificate of designation, preferences
or rights of any other outstanding series of preferred stock of the Company or any of its Subsidiaries or Bylaws or their organizational
charter, certificate of formation, memorandum of association, articles of association, Certificate of Incorporation or certificate
of incorporation or bylaws, respectively. Neither the Company nor any of its Subsidiaries is in violation of any judgment, decree
or order or any statute, ordinance, rule or regulation applicable to the Company or any of its Subsidiaries, and neither the Company
nor any of its Subsidiaries will conduct its business in violation of any of the foregoing, except in all cases for possible violations
which could not, individually or in the aggregate, have a Material Adverse Effect. Without limiting the generality of the foregoing,
the Company is not in violation of any of the rules, regulations or requirements of the Principal Market and has no knowledge
of any facts or circumstances that could reasonably lead to delisting or suspension of the Common Stock by the Principal Market
in the foreseeable future. During the two years prior to the date hereof, (i) the Common Stock has been listed or designated for
quotation on the Principal Market, (ii) trading in the Common Stock has not been suspended by the SEC or the Principal Market
and (iii) the Company has received no communication, written or oral, from the SEC or the Principal Market regarding the suspension
or delisting of the Common Stock from the Principal Market. The Company and each of its Subsidiaries possess all certificates,
authorizations and permits issued by the appropriate regulatory authorities necessary to conduct their respective businesses,
except where the failure to possess such certificates, authorizations or permits would not have, individually or in the aggregate,
a Material Adverse Effect, and neither the Company nor any such Subsidiary has received any notice of proceedings relating to
the revocation or modification of any such certificate, authorization or permit. There is no agreement, commitment, judgment,
injunction, order or decree binding upon the Company or any of its Subsidiaries or to which the Company or any of its Subsidiaries
is a party which has or would reasonably be expected to have the effect of prohibiting or materially impairing any business practice
of the Company or any of its Subsidiaries, any acquisition of property by the Company or any of its Subsidiaries or the conduct
of business by the Company or any of its Subsidiaries as currently conducted other than such effects, individually or in the aggregate,
which have not had and would not reasonably be expected to have a Material Adverse Effect on the Company or any of its Subsidiaries.

(o) Foreign
Corrupt Practices. Neither the Company, the Company’s subsidiary or any director, officer, agent, employee, nor any
other person acting for or on behalf of the foregoing (individually and collectively, a “Company Affiliate”)
have violated the U.S. Foreign Corrupt Practices Act (the “FCPA”) or any other applicable anti-bribery or anti-corruption
laws, nor has any Company Affiliate knowingly offered, paid, promised to pay, or authorized the payment of any money, or offered,
given, promised to give, or authorized the giving of anything of value, to any officer, employee or any other person acting in
an official capacity for any Governmental Entity to any political party or official thereof or to any candidate for political
office (individually and collectively, a “Government Official”) or to any person under circumstances where
such Company Affiliate knew or was aware of a high probability that all or a portion of such money or thing of value would be
offered, given or promised, directly or indirectly, to any Government Official, for the purpose of:

 

(i) (A)
influencing any act or decision of such Government Official in his/her official capacity, (B) inducing such Government Official
to do or omit to do any act in violation of his/her lawful duty, (C) securing any improper advantage, or (D) inducing such Government
Official to influence or affect any act or decision of any Governmental Entity, or

requirements of the Sarbanes-Oxley Act of 2002, as amended, and any and all applicable rules and regulations promulgated by the
SEC thereunder.

 

(q) Transactions
With Affiliates. Except as disclosed in the SEC Documents, no current or former
employee, partner, director, officer or stockholder (direct or indirect) of the Company or its Subsidiaries, or any associate,
or, to the knowledge of the Company, any affiliate of any thereof, or any relative with a relationship no more remote than first
cousin of any of the foregoing, is presently, or has ever been, (i) a party to any transaction with the Company or its Subsidiaries
(including any contract, agreement or other arrangement providing for the furnishing of services by, or rental of real or personal
property from, or otherwise requiring payments to, any such director, officer or stockholder or such associate or affiliate or
relative Subsidiaries (other than for ordinary course services as employees, officers or directors of the Company or any of its
Subsidiaries)) or (ii) the direct or indirect owner of an interest in any corporation, firm, association or business organization
which is a competitor, supplier or customer of the Company or its Subsidiaries (except for a passive investment (direct or indirect)
in less than 5% of the common stock of a company whose securities are traded on or quoted through an Eligible Market (as defined
in the Notes)), nor does any such Person receive income from any source other than the Company or its Subsidiaries which relates
to the business of the Company or its Subsidiaries or should properly accrue to the Company or its Subsidiaries. No employee,
officer, stockholder or director of the Company or any of its Subsidiaries or member of his or her immediate family is indebted
to the Company or its Subsidiaries, as the case may be, nor is the Company or any of its Subsidiaries indebted (or committed to
make loans or extend or guarantee credit) to any of them, other than (i) for payment of salary for services rendered, (ii) reimbursement
for reasonable expenses incurred on behalf of the Company, and (iii) for other standard employee benefits made generally available

to the Company’s knowledge, no Person owns 10% or more of the Company’s issued and outstanding shares of Common Stock

or conversion (including “blockers”) contained therein without conceding that such identified Person is a 10% stockholder
for purposes of federal securities laws).

Company’s bylaws, as amended and as in effect on the date hereof (the “Bylaws”), and the terms of all
Convertible Securities and the material rights of the holders thereof in respect thereto.

 

(s) Indebtedness
and Other Contracts. Neither the Company nor any of its Subsidiaries, (i) except
as disclosed on Schedule 3(r), has any outstanding debt securities, notes, credit agreements, credit facilities or

which are not so disclosed in the SEC Documents, other than those incurred in the ordinary course of the Company’s or its
Subsidiaries’ respective businesses and which, individually or in the aggregate, do not or could not have a Material Adverse
Effect. For purposes of this Agreement: (x) “Indebtedness” of any Person means, without duplication (A) all

owns such assets or property has not assumed or become liable for the payment of such indebtedness, and (H) all Contingent Obligations
in respect of indebtedness or obligations of others of the kinds referred to in clauses (A) through (G) above; and (y) “Contingent
Obligation” means, as to any Person, any direct or indirect liability, contingent or otherwise, of that Person with
respect to any Indebtedness, lease, dividend or other obligation of another Person if the primary purpose or intent of the Person
incurring such liability, or the primary effect thereof, is to provide assurance to the obligee of such liability that such liability
will be paid or discharged, or that any agreements relating thereto will be complied with, or that the holders of such liability
will be protected (in whole or in part) against loss with respect thereto.

(t) Litigation.
There is no action, suit, arbitration, proceeding, inquiry or investigation before or by the Principal Market, any court, public
board, other Governmental Entity, self-regulatory organization or body pending or, to the knowledge of the Company, threatened
against or affecting the Company or any of its Subsidiaries, the Common Stock or any of the Company’s or its Subsidiaries’
executive officers or directors, whether of a civil or criminal nature or otherwise, in their capacities as such, except as disclosed
in the SEC Documents or asset forth on Schedule 3(t) or disclosed in the SEC Documents. No director, officer or employee
of the Company or any of its subsidiaries has willfully violated 18 U.S.C. §1519 or engaged in spoliation in reasonable anticipation
of litigation. Without limitation of the foregoing, there has not been, and to the knowledge of the Company, there is not pending
or contemplated, any investigation by the SEC involving the Company, any of its Subsidiaries or any current or former director
or officer of the Company or any of its Subsidiaries. The SEC has not issued any stop order or other order suspending the effectiveness
of any registration statement filed by the Company under the 1933 Act or the 1934 Act. After reasonable inquiry of its employees,
the Company is not aware of any fact which might result in or form the basis for any such action, suit, arbitration, investigation,
inquiry or other proceeding. Neither the Company nor any of its Subsidiaries is subject to any order, writ, judgment, injunction,
decree, determination or award of any Governmental Entity.

 

(u) Insurance.
The Company and each of its Subsidiaries are insured by insurers of recognized financial responsibility against such losses and
risks and in such amounts as management of the Company believes to be prudent and customary in the businesses in which the Company
and its Subsidiaries are engaged. Neither the Company nor any such Subsidiary has been refused any insurance coverage sought or
applied for, and neither the Company nor any such Subsidiary has any reason to believe that it will be unable 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 at a cost that would not have a Material Adverse Effect.

 

(v) Employee
Relations. Neither the Company nor any of its Subsidiaries is a party to any collective
bargaining agreement or employs any member of a union. The Company and its Subsidiaries believe that their relations with their
employees are good. No executive officer (as defined in Rule 501(f) promulgated under the 1933 Act) or other key employee of the
Company or any of its Subsidiaries has notified the Company or any such Subsidiary that such officer intends to leave the Company
or any such Subsidiary or otherwise terminate such officer’s employment with the Company or any such Subsidiary. No executive
officer or other key employee of the Company or any of its Subsidiaries is, or is now expected to be, in violation of any material
term of any employment contract, confidentiality, disclosure or proprietary information agreement, non-competition agreement,
or any other contract or agreement or any restrictive covenant, and the continued employment of each such executive officer or
other key employee (as the case may be) does not subject the Company or any of its Subsidiaries to any liability with respect
to any of the foregoing matters. The Company and its Subsidiaries are in compliance with all federal, state, local and foreign
laws and regulations respecting labor, employment and employment practices and benefits, terms and conditions of employment and
wages and hours, except where failure to be in compliance would not, either individually or in the aggregate, reasonably be expected
to result in a Material Adverse Effect.

 

(w) Title.

 

(i) Real
Property. Except as disclosed on Schedule 3(w)(i), each of the Company and its Subsidiaries holds good title to all
real property, leases in real property, facilities or other interests in real property owned or held by the Company or any of its
Subsidiaries (the “Real Property”) owned by the Company or any of its Subsidiaries (as applicable). The Real
Property is free and clear of all Liens and is not subject to any rights of way, building use restrictions, exceptions, variances,
reservations, or limitations of any nature except for (a) Liens for current taxes not yet due and (b) zoning laws and other land
use restrictions that do not impair the present or anticipated use of the property subject thereto. Any Real Property held under
lease by the Company or any of its Subsidiaries are held by them under valid, subsisting and enforceable leases with such exceptions
as are not material and do not interfere with the use made and proposed to be made of such property and buildings by the Company
or any of its Subsidiaries.

(ii) Fixtures
and Equipment. Except as set forth on Schedule 3(w)(ii), each of the Company and its Subsidiaries (as applicable) has
good title to, or a valid leasehold interest in, the tangible personal property, equipment, improvements, fixtures, and other personal
property and appurtenances that are used by the Company or its Subsidiary in connection with the conduct of its business (the “Fixtures
and Equipment”). The Fixtures and Equipment are structurally sound, are in good operating condition and repair, are adequate
for the uses to which they are being put, are not in need of maintenance or repairs except for ordinary, routine maintenance and
repairs and are sufficient for the conduct of the Company’s and/or its Subsidiaries’ businesses (as applicable) in
the manner as conducted prior to the Closing. Except as set forth on Schedule 3(w)(ii), each of the Company and its Subsidiaries
owns all of its Fixtures and Equipment free and clear of all Liens except for (a) liens for current taxes not yet due and (b) zoning
laws and other land use restrictions that do not impair the present or anticipated use of the property subject thereto.

 

(x) Intellectual
Property Rights. The Company and its Subsidiaries own or possess adequate rights
or licenses to use all trademarks, trade names, service marks, service mark registrations, service names, original works of authorship,
patents, patent rights, copyrights, inventions, licenses, approvals, governmental authorizations, trade secrets and other intellectual
property rights and all applications and registrations therefor (“Intellectual Property Rights”) necessary
to conduct their respective businesses as now conducted and presently proposed to be conducted. Each of patents owned by the Company
or any of its Subsidiaries is listed on Schedule 3(x)(i). Except as set forth in Schedule 3(x)(ii), none of the
Company’s Intellectual Property Rights have expired or terminated or have been abandoned or are expected to expire or terminate
or are expected to be abandoned, within three years from the date of this Agreement. The Company does not have any knowledge of
any infringement by the Company or its Subsidiaries of Intellectual Property Rights of others. There is no claim, action or proceeding
being made or brought, or to the knowledge of the Company or any of its Subsidiaries, being threatened, against the Company or
any of its Subsidiaries regarding its Intellectual Property Rights. Neither the Company nor any of its Subsidiaries is aware of
any facts or circumstances which might give rise to any of the foregoing infringements or claims, actions or proceedings. The
Company and its Subsidiaries have taken reasonable security measures to protect the secrecy, confidentiality and value of all
of their Intellectual Property Rights.

 

(y) Environmental
Laws. (i) The Company and its Subsidiaries (A) are in compliance with any and all Environmental Laws (as defined below), (B)
have received all permits, licenses or other approvals required of them under applicable Environmental Laws to conduct their respective
businesses and (C) are in compliance with all terms and conditions of any such permit, license or approval where, in each of the
foregoing clauses (A), (B) and (C), the failure to so comply could be reasonably expected to have, individually or in the aggregate,
a Material Adverse Effect. The term “Environmental Laws” means all federal, state, local or foreign laws relating
to pollution or protection of human health or the environment (including, without limitation, ambient air, surface water, groundwater,
land surface or subsurface strata), including, without limitation, laws relating to emissions, discharges, releases or threatened
releases of chemicals, pollutants, contaminants, or toxic or hazardous substances or wastes (collectively, “Hazardous
Materials”) into the environment, or otherwise relating to the manufacture, processing, distribution, use, treatment,
storage, disposal, transport or handling of Hazardous Materials, as well as all authorizations, codes, decrees, demands or demand
letters, injunctions, judgments, licenses, notices or notice letters, orders, permits, plans or regulations issued, entered, promulgated
or approved thereunder.

(ii) No
Hazardous Materials:

 

(A) have
been disposed of or otherwise released from any Real Property of the Company or any of its Subsidiaries in violation of any Environmental
Laws; or

 

(B) are
present on, over, beneath, in or upon any Real Property or any portion thereof in quantities that would constitute a violation
of any Environmental Laws. No prior use by the Company or any of its Subsidiaries of any Real Property has occurred that violates
any Environmental Laws, which violation would have a material adverse effect on the business of the Company or any of its Subsidiaries.

 

(iii) Neither
the Company nor any of its Subsidiaries knows of any other person who or entity which has stored, treated, recycled, disposed of
or otherwise located on any Real Property any Hazardous Materials, including, without limitation, such substances as asbestos and
polychlorinated biphenyls.

 

(iv) None
of the Real Properties are on any federal or state “y D” list or Liability Information System (“CERCLIS”)
list or any state environmental agency list of sites under consideration for CERCLIS, nor subject to any environmental related
Liens.

 

(z) Subsidiary
Rights. The Company or one of its Subsidiaries has the unrestricted right to vote,
and (subject to limitations imposed by applicable law) to receive dividends and distributions on, all capital securities of its
Subsidiaries as owned by the Company or such Subsidiary.

 

(aa) Tax Status.
The Company and each of its Subsidiaries (i) has timely made or filed all foreign, federal and state income and all other tax
returns, reports and declarations required by any jurisdiction to which it is subject, (ii) has timely 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,
except those being contested in good faith and (iii) has set aside on its books provision reasonably adequate for the payment
of all 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 and its
Subsidiaries know of no basis for any such claim. The Company is not operated in such a manner as to qualify as a passive foreign
investment company, as defined in Section 1297 of the Code. The net operating loss carryforwards (“NOLs”) for
United States federal income tax purposes of the consolidated group of which the Company is the common parent, if any, shall not
be adversely effected by the transactions contemplated hereby. The transactions contemplated hereby do not constitute an “ownership
change” within the meaning of Section 382 of the Code, thereby preserving the Company’s ability to utilize such NOLs.

 

    -15-

     

    

 

(bb) Internal
Accounting and Disclosure Controls . The Company and each of its Subsidiaries maintains
internal control over financial reporting (as such term is defined in Rule 13a-15(f) under the 1934 Act) that is effective to
provide reasonable assurance regarding the reliability of financial reporting and the preparation of financial statements for
external purposes in accordance with generally accepted accounting principles, including 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 and liability accountability, (iii) access to assets or
incurrence of liabilities is permitted only in accordance with management’s general or specific authorization and (iv) the
recorded accountability for assets and liabilities is compared with the existing assets and liabilities at reasonable intervals
and appropriate action is taken with respect to any difference. The Company maintains disclosure controls and procedures (as such
term is defined in Rule 13a-15(e) under the 1934 Act) that are effective in ensuring that information required to be disclosed
by the Company in the reports that it files or submits under the 1934 Act is recorded, processed, summarized and reported, within
the time periods specified in the rules and forms of the SEC, including, without limitation, controls and procedures designed
to ensure that information required to be disclosed by the Company in the reports that it files or submits under the 1934 Act
is accumulated and communicated to the Company’s management, including its principal executive officer or officers and its
principal financial officer or officers, as appropriate, to allow timely decisions regarding required disclosure. Neither the
Company nor any of its Subsidiaries has received any notice or correspondence from any accountant, Governmental Entity or other
Person relating to any potential material weakness or significant deficiency in any part of the internal controls over financial
reporting of the Company or any of its Subsidiaries.

 

(cc) Off Balance
Sheet Arrangements. There is no transaction, arrangement, or other relationship
between the Company or any of its Subsidiaries and an unconsolidated or other off balance sheet entity that is required to be
disclosed by the Company in its 1934 Act filings and is not so disclosed or that otherwise could be reasonably likely to have
a Material Adverse Effect.

 

(dd) Investment
Company Status. The Company is not, and upon consummation of the sale of the Securities
will not be, an “investment company,” an affiliate of an “investment company,” a company controlled by
an “investment company” or an “affiliated person” of, or “promoter” or “principal underwriter”
for, an “investment company” as such terms are defined in the Investment Company Act of 1940, as amended.

without limitation, purchasing or selling, long and/or short) any securities of the Company, or “derivative” securities
based on securities issued by the Company or to hold any of the Securities for any specified term; (ii) any Buyer, and counterparties
in “derivative” transactions to which any such Buyer is a party, directly or indirectly, presently may have a “short”
position in the Common Stock which was established prior to such Buyer’s knowledge of the transactions contemplated by the
Transaction Documents; (iii) each Buyer shall not be deemed to have any affiliation with or control over any arm’s length
counterparty in any “derivative” transaction; and (iv) each Buyer may rely on the Company’s obligation to timely
deliver shares of Common Stock upon conversion, exercise or exchange, as applicable, of the Securities as and when required pursuant
to the Transaction Documents for purposes of effecting trading in the Common Stock of the Company. The Company further understands
and acknowledges that following the public disclosure of the transactions contemplated by the Transaction Documents pursuant to
the Press Release (as defined below) one or more Buyers may engage in hedging and/or trading activities (including, without limitation,
the location and/or reservation of borrowable shares of Common Stock) at various times during the period that the Securities are
outstanding, including, without limitation, during the periods that the value and/or number of the Warrant Shares or Conversion
Shares, as applicable, deliverable with respect to the Securities are being determined and such hedging and/or trading activities
(including, without limitation, the location and/or reservation of borrowable shares of Common Stock), if any, can reduce the
value of the existing stockholders’ equity interest in the Company both at and after the time the hedging and/or trading
activities are being conducted. The Company acknowledges that such aforementioned hedging and/or trading activities do not constitute

herewith or therewith.

(ww) Disclosure.
The Company confirms that neither it nor any other Person acting on its behalf has provided any of the Buyers or their agents
or counsel with any information that constitutes or could reasonably be expected to constitute material, non-public information
concerning the Company or any of its Subsidiaries, other than the existence of the transactions contemplated by this Agreement
and the other Transaction Documents. The Company understands and confirms that each of the Buyers will rely on the foregoing representations
in effecting transactions in securities of the Company. All disclosure provided to the Buyers regarding the Company and its Subsidiaries,
their businesses and the transactions contemplated hereby, including the schedules to this Agreement, furnished by or on behalf
of the Company or any of its Subsidiaries 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. All of the written information furnished after the date hereof by or on behalf of the Company
or any of its Subsidiaries to each Buyer pursuant to or in connection with this Agreement and the other Transaction Documents,
taken as a whole, will be true and correct in all material respects as of the date on which such information is so provided and
will 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. Each press release issued by the Company
or any of its Subsidiaries during the twelve (12) months preceding the date of this Agreement did not at the time of release 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 are made, not misleading. No event or circumstance
has occurred or information exists with respect to the Company or any of its Subsidiaries or its or their business, properties,
liabilities, prospects, operations (including results thereof) or conditions (financial or otherwise), which, under applicable
law, rule or regulation, requires public disclosure at or before the date hereof or announcement by the Company but which has
not been so publicly disclosed. All financial projections and forecasts that have been prepared by or on behalf of the Company
or any of its Subsidiaries and made available to you have been prepared in good faith based upon reasonable assumptions and represented,
at the time each such financial projection or forecast was delivered to each Buyer, the Company’s best estimate of future
financial performance (it being recognized that such financial projections or forecasts are not to be viewed as facts and that
the actual results during the period or periods covered by any such financial projections or forecasts may differ from the projected
or forecasted results). The Company acknowledges and agrees that no Buyer makes or has made any representations or warranties
with respect to the transactions contemplated hereby other than those specifically set forth in Section 2.

of Securities. Notwithstanding anything to the contrary contained in this Agreement,
the Company acknowledges and agrees that the Securities may be pledged by an Investor (as defined in the Registration Rights Agreement)
in connection with a bona fide margin agreement or other loan or financing arrangement that is secured by the Securities. The
pledge of Securities shall not be deemed to be a transfer, sale or assignment of the Securities hereunder, and no Investor effecting
a pledge of Securities shall be required to provide the Company with any notice thereof or otherwise make any delivery to the
Company pursuant to this Agreement or any other Transaction Document, including, without limitation, Section 2(g) hereof; provided
that an Investor and its pledgee shall be required to comply with the provisions of Section 2(g) hereof in order to effect

(ii) Limitations
on Disclosure. The Company shall not, and the Company shall cause each of its Subsidiaries and each of its and their respective
officers, directors, employees and agents not to, provide any Buyer with any material, non-public information regarding the Company
or any of its Subsidiaries from and after the date hereof without the express prior written consent of such Buyer (which may be
granted or withheld in such Buyer’s sole discretion). In the event of a breach of any of the foregoing covenants, or any
of the covenants or agreements contained in any other Transaction Document, by the Company, any of its Subsidiaries, or any of
its or their respective officers, directors, employees and agents (as determined in the reasonable good faith judgment of such
Buyer), in addition to any other remedy provided herein or in the Transaction Documents, such Buyer shall have the right to make
a public disclosure, in the form of a press release, public advertisement or otherwise, of such breach or such material, non-public
information, as applicable, without the prior approval by the Company, any of its Subsidiaries, or any of its or their respective
officers, directors, employees or agents. No Buyer shall have any liability to the Company, any of its Subsidiaries, or any of
its or their respective officers, directors, employees, affiliates, stockholders or agents, for any such disclosure. To the extent
that the Company delivers any material, non-public information to a Buyer without such Buyer’s consent, the Company hereby
covenants and agrees that such Buyer shall not have any duty of confidentiality with respect to, or a duty not to trade on the

public disclosure with respect to such transactions (i) in substantial conformity with the 8-K Filing and contemporaneously therewith
and (ii) as is required by applicable law and regulations (provided that in the case of clause (i) each Buyer shall be consulted
by the Company in connection with any such press release or other public disclosure prior to its release). Without the prior written
consent of the applicable Buyer (which may be granted or withheld in such Buyer’s sole discretion), the Company shall not

or otherwise except as otherwise required by law or as contemplated by this Agreement or the other Transaction Documents. Notwithstanding
anything contained in this Agreement to the contrary and without implication that the contrary would otherwise be true, the Company
expressly acknowledges and agrees that no Buyer shall have (unless expressly agreed to by a particular Buyer after the date hereof
in a written definitive and binding agreement executed by the Company and such particular Buyer (it being understood and agreed
that no Buyer may bind any other Buyer with respect thereto)), any duty of confidentiality with respect to, or a duty not to trade
on the basis of, any material, non-public information regarding the Company or any of its Subsidiaries.

a registration statement or an offering statement under the 1933 Act relating to securities that are not the Registrable Securities
(other than a registration statement on Form S-8 or such supplements or amendments to registration statements that are outstanding

the Company will not, without the prior written consent of the Required Holders, issue any Notes (other than to the Buyers as
contemplated hereby) or other securities that would cause a breach or default under the Notes or the Warrants. The Company agrees
that for the period commencing on the date hereof and ending on the date immediately following the 90th calendar days
after the Applicable Date (provided that such period shall be extended by the number of calendar days during such period and any
extension thereof contemplated by this proviso on which any Registration Statement is not effective or any prospectus contained
therein is not available for use or any Current Public Information Failure exists) (the “Restricted Period”),

than 25% of the Common Stock issued and outstanding immediately prior to the date hereof and (2) the exercise price of any such
options is not lowered, none of such options are amended to increase the number of shares issuable thereunder and none of the

provided that the conversion, exercise or other method of issuance (as the case may be) of any such Convertible Security is made
solely pursuant to the conversion, exercise or other method of issuance (as the case may be) provisions of such Convertible Security
that were in effect on the date immediately prior to the date of this Agreement, the conversion, exercise or issuance price of
any such Convertible Securities (other than standard options to purchase Common Stock issued pursuant to an Approved Stock Plan
that are covered by clause (i) above) is not lowered, none of such Convertible Securities (other than standard options to purchase
Common Stock issued pursuant to an Approved Stock Plan that are covered by clause (i) above) are amended to increase the number

to purchase Common Stock issued pursuant to an Approved Stock Plan that are covered by clause (i) above) are otherwise materially
changed in any manner that adversely affects any of the Buyers; (iii) any shares of Common Stock issued or issuable in connection
with any bona fide strategic or commercial alliances, acquisitions, mergers, licensing arrangements, and strategic partnerships,

commercial alliances, acquisitions, mergers, licensing arrangements, and strategic partnerships, as applicable, has been approved
by a majority of the independent members of the board of directors of the Company, (y) the purchaser or acquirer or recipient
of the securities in such issuance solely consists of either (A) the actual participants in such strategic or commercial alliance,
strategic or commercial licensing arrangement or strategic or commercial partnership, (B) the actual owners of such assets or
securities acquired in such acquisition or merger or (C) the stockholders, partners, employees, consultants, officers, directors
or members of the foregoing Persons, in each case, which is, itself or through its subsidiaries, an operating company or an owner
of an asset, in a business synergistic with the business of the Company and shall provide to the Company additional benefits in
addition to the investment of funds, and (z) the number or amount of securities issued to such Persons by the Company shall not
be disproportionate to each such Person’s actual participation in (or fair market value of the contribution to) such strategic
or commercial alliance or strategic or commercial partnership or ownership of such assets or securities to be acquired by the
Company, as applicable; (iv) the Conversion Shares, and (v) the Warrant Shares (each of the foregoing in clauses (i) through (v),

hereof that (x) the Notes are convertible at the Alternate Conversion Price assuming an Alternate Conversion Date as of such date
of determination, and (y) any such conversion shall not take into account any limitations on the conversion of the Notes set forth
in the Notes), and (ii) the maximum number of Warrant Shares issuable upon exercise of all the Warrants then outstanding (without
regard to any limitations on the exercise of the Warrants set forth therein) (collectively, the “Required Reserve Amount”);
provided that at no time shall the number of shares of Common Stock reserved pursuant to this Section 4(l) be reduced other than
proportionally in connection with any conversion, exercise and/or redemption, as applicable of Notes and Warrants. If at any time
the number of shares of Common Stock authorized and reserved for issuance is not sufficient to meet the Required Reserve Amount,
the Company will promptly take all corporate action necessary to authorize and reserve a sufficient number of shares, including,
without limitation, calling a special meeting of stockholders to authorize additional shares to meet the Company’s obligations
pursuant to the Transaction Documents, in the case of an insufficient number of authorized shares, obtain stockholder approval

Issuances. For so long as any Notes remain outstanding, the Company shall not,

Warrants without breaching the Company’s obligations under the rules or regulations of the Principal Market.

(b) Transfer
Agent Instructions. The Company shall issue irrevocable instructions to its transfer
agent and any subsequent transfer agent (as applicable, the “Transfer Agent”) in a form acceptable to each
of the Buyers (the “Irrevocable Transfer Agent Instructions”) to issue certificates or credit shares to the
applicable balance accounts at The Depository Trust Company (“DTC”), registered in the name of each Buyer or
its respective nominee(s), for the Conversion Shares and the Warrant Shares in such amounts as specified from time to time by
each Buyer to the Company upon conversion of the Notes or the exercise of the Warrants (as the case may be). The Company represents
and warrants that no instruction other than the Irrevocable Transfer Agent Instructions referred to in this Section 5(b),
and stop transfer instructions to give effect to Section 2(g) hereof, will be given by the Company to its transfer agent with
respect to the Securities, and that the Securities shall otherwise be freely transferable on the books and records of the Company,
as applicable, to the extent provided in this Agreement and the other Transaction Documents. If a Buyer effects a sale, assignment
or transfer of the Securities in accordance with Section 2(g), the Company shall permit the transfer and shall promptly instruct
its transfer agent to issue one or more certificates or credit shares to the applicable balance accounts at DTC in such name and
in such denominations as specified by such Buyer to effect such sale, transfer or assignment. In the event that such sale, assignment
or transfer involves Conversion Shares or Warrant Shares sold, assigned or transferred pursuant to an effective registration statement
or in compliance with Rule 144, the transfer agent shall issue such shares to such Buyer, assignee or transferee (as the case
may be) without any restrictive legend in accordance with Section 5(d) below. The Company acknowledges that a breach by it
of its obligations hereunder will cause irreparable harm to a Buyer. Accordingly, the Company acknowledges that the remedy at
law for a breach of its obligations under this Section 5(b) will be inadequate and agrees, in the event of a breach or threatened
breach by the Company of the provisions of this Section 5(b), that a Buyer shall be entitled, in addition to all other available
remedies, to an order and/or injunction restraining any breach and requiring immediate issuance and transfer, without the necessity
of showing economic loss and without any bond or other security being required. The Company shall cause its counsel to issue the
legal opinion referred to in the Irrevocable Transfer Agent Instructions to the Company’s transfer agent on each Effective
Date (as defined in the Registration Rights Agreement). Any fees (with respect to the transfer agent, counsel to the Company or
otherwise) associated with the issuance of such opinion or the removal of any legends on any of the Securities shall be borne
by the Company.

 

(c) Legends.
Each Buyer understands that the Securities have been issued (or will be issued in the case of the Conversion Shares and the Warrant
Shares) pursuant to an exemption from registration or qualification under the 1933 Act and applicable state securities laws, and
except as set forth below, the Securities shall bear any legend as required by the “blue sky” laws of any state and
a restrictive legend in substantially the following form (and a stop-transfer order may be placed against transfer of such stock
certificates):

 

[NEITHER THE ISSUANCE AND SALE OF THE
SECURITIES REPRESENTED BY THIS CERTIFICATE NOR THE SECURITIES INTO WHICH THESE SECURITIES ARE [CONVERTIBLE] [EXERCISABLE] HAVE
BEEN][THE SECURITIES REPRESENTED BY THIS CERTIFICATE HAVE NOT BEEN] REGISTERED UNDER THE SECURITIES ACT OF 1933, AS AMENDED, OR
APPLICABLE STATE SECURITIES LAWS. THE SECURITIES MAY NOT BE OFFERED FOR SALE, SOLD, TRANSFERRED OR ASSIGNED (I) IN THE ABSENCE
OF (A) AN EFFECTIVE REGISTRATION STATEMENT FOR THE SECURITIES UNDER THE SECURITIES ACT OF 1933, AS AMENDED, OR (B) AN OPINION OF
COUNSEL TO THE HOLDER (IF REQUESTED BY THE COMPANY), IN A FORM REASONABLY ACCEPTABLE TO THE COMPANY, THAT REGISTRATION IS NOT REQUIRED
UNDER SAID ACT OR (II) UNLESS SOLD OR ELIGIBLE TO BE SOLD PURSUANT TO RULE 144 OR RULE 144A UNDER SAID ACT. NOTWITHSTANDING THE
FOREGOING, THE SECURITIES MAY BE PLEDGED IN CONNECTION WITH A BONA FIDE MARGIN ACCOUNT OR OTHER LOAN OR FINANCING ARRANGEMENT SECURED
BY THE SECURITIES.

 

    -29-

     

    

 

(d) Removal
of Legends. Certificates evidencing Securities shall not be required to contain
the legend set forth in Section 5(c) above or any other legend (i) while a registration statement (including a Registration
Statement) covering the resale of such Securities is effective under the 1933 Act (if prior to the sale of such applicable Securities,
subject to the Holder’s delivery of a reasonable representation letter with respect thereto to the Company), (ii) following
any sale of such Securities pursuant to Rule 144 (assuming the transferor is not an affiliate of the Company), (iii) if such Securities
are eligible to be sold, assigned or transferred under Rule 144 (provided that a Buyer provides the Company with reasonable assurances
that such Securities are eligible for sale, assignment or transfer under Rule 144 which shall not include an opinion of Buyer’s
counsel), (iv) in connection with a sale, assignment or other transfer (other than under Rule 144), provided that such Buyer provides
the Company with an opinion of counsel to such Buyer, in a generally acceptable form, to the effect that such sale, assignment
or transfer of the Securities may be made without registration under the applicable requirements of the 1933 Act or (v) if such
legend is not required under applicable requirements of the 1933 Act (including, without limitation, controlling judicial interpretations
and pronouncements issued by the SEC). If a legend is not required pursuant to the foregoing, the Company shall no later than
two (2) Trading Days (as defined in the Notes) (or such earlier date as required pursuant to the 1934 Act or other applicable
law, rule or regulation for the settlement of a trade initiated on the date such Buyer delivers such legended certificate representing
such Securities to the Company) following the delivery by a Buyer to the Company or the transfer agent (with notice to the Company)
of a legended certificate representing such Securities (endorsed or with stock powers attached, signatures guaranteed, and otherwise
in form necessary to affect the reissuance and/or transfer, if applicable), together with any other deliveries from such Buyer
as may be required above in this Section 5(d), as directed by such Buyer, either: (A) provided that the Company’s transfer
agent is participating in the DTC Fast Automated Securities Transfer Program and such Securities are Conversion Shares or Warrant
Shares, credit the aggregate number of shares of Common Stock to which such Buyer shall be entitled to such Buyer’s or its
designee’s balance account with DTC through its Deposit/Withdrawal at Custodian system or (B) if the Company’s transfer
agent is not participating in the DTC Fast Automated Securities Transfer Program, issue and deliver (via reputable overnight courier)
to such Buyer, a certificate representing such Securities that is free from all restrictive and other legends, registered in the
name of such Buyer or its designee (the date by which such credit is so required to be made to the balance account of such Buyer’s
or such Buyer’s designee with DTC or such certificate is required to be delivered to such Buyer pursuant to the foregoing
is referred to herein as the “Required Delivery Date”, and the date such shares of Common Stock are actually
delivered without restrictive legend to such Buyer or such Buyer’s designee with DTC, as applicable, the “Share
Delivery Date”). The Company shall be responsible for any transfer agent fees or DTC fees with respect to any issuance
of Securities or the removal of any legends with respect to any Securities in accordance herewith.

 

    -30-

     

    

 

(e) Failure
to Timely Deliver; Buy-In. If the Company fails to fail, for any reason or for
no reason, to issue and deliver (or cause to be delivered) to a Buyer (or its designee) by the Required Delivery Date, either
(I) if the Transfer Agent is not participating in the DTC Fast Automated Securities Transfer Program, a certificate for the number
of Conversion Shares or Warrant Shares (as the case may be) to which such Buyer is entitled and register such Conversion Shares
or Warrant Shares (as the case may be) on the Company’s share register or, if the Transfer Agent is participating in the
DTC Fast Automated Securities Transfer Program, to credit the balance account of such Buyer or such Buyer’s designee with
DTC for such number of Conversion Shares or Warrant Shares (as the case may be) submitted for legend removal by such Buyer pursuant
to Section 5(d) above or (II) if the Registration Statement covering the resale of the Conversion Shares or Warrant Shares (as
the case may be) submitted for legend removal by such Buyer pursuant to Section 5(d) above (the “Unavailable Shares”)
is not available for the resale of such Unavailable Shares and the Company fails to promptly, but in no event later than as required
pursuant to the Registration Rights Agreement (x) so notify such Buyer and (y) deliver the Conversion Shares or Warrant Shares,
as applicable, electronically without any restrictive legend by crediting such aggregate number of Conversion Shares or Warrant
Shares (as the case may be) submitted for legend removal by such Buyer pursuant to Section 5(d) above to such Buyer’s or
its designee’s balance account with DTC through its Deposit/Withdrawal At Custodian system (the event described in the immediately
foregoing clause (II) is hereinafter referred as a “Notice Failure” and together with the event described in
clause (I) above, a “Delivery Failure”), then, in addition to all other remedies available to such Buyer, the
Company shall pay in cash to such Buyer on each day after the Share Delivery Date and during such Delivery Failure an amount equal
to 2% of the product of (A) the sum of the number of shares of Common Stock not issued to such Buyer on or prior to the Required
Delivery Date and to which such Buyer is entitled, and (B) any trading price of the Common Stock selected by such Buyer in writing
as in effect at any time during the period beginning on the date of the delivery by such Buyer to the Company of the applicable
Conversion Shares or Warrant Shares (as the case may be) and ending on the applicable Share Delivery Date. In addition to the
foregoing, if on or prior to the Required Delivery Date either (I) if the Transfer Agent is not participating in the DTC Fast
Automated Securities Transfer Program, the Company shall fail to issue and deliver a certificate to a Buyer and register such
shares of Common Stock on the Company’s share register or, if the Transfer Agent is participating in the DTC Fast Automated
Securities Transfer Program, credit the balance account of such Buyer or such Buyer’s designee with DTC for the number of
shares of Common Stock to which such Buyer submitted for legend removal by such Buyer pursuant to Section 5(d) above (ii) below
or (II) a Notice Failure occurs, and if on or after such Trading Day such Buyer purchases (in an open market transaction or otherwise)
shares of Common Stock to deliver in satisfaction of a sale by such Buyer of shares of Common Stock submitted for legend removal
by such Buyer pursuant to Section 5(d) above that such Buyer is entitled to receive from the Company (a “Buy-In”),
then the Company shall, within two (2) Trading Days after such Buyer’s request and in such Buyer’s discretion, either
(i) pay cash to such Buyer in an amount equal to such Buyer’s total purchase price (including brokerage commissions and
other out-of-pocket expenses, if any, for the shares of Common Stock so purchased) (the “Buy-In Price”), at
which point the Company’s obligation to so deliver such certificate or credit such Buyer’s balance account shall terminate
and such shares shall be cancelled, or (ii) promptly honor its obligation to so deliver to such Buyer a certificate or certificates
or credit the balance account of such Buyer or such Buyer’s designee with DTC representing such number of shares of Common
Stock that would have been so delivered if the Company timely complied with its obligations hereunder and pay cash to such Buyer
in an amount equal to the excess (if any) of the Buy-In Price over the product of (A) such number of shares of Conversion Shares
or Warrant Shares (as the case may be) that the Company was required to deliver to such Buyer by the Required Delivery Date multiplied
by (B) the lowest Closing Sale Price (as defined in the Warrants) of the Common Stock on any Trading Day during the period commencing
on the date of the delivery by such Buyer to the Company of the applicable Conversion Shares or Warrant Shares (as the case may
be) and ending on the date of such delivery and payment under this clause (ii). Nothing shall limit such Buyer’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 certificates representing shares
of Common Stock (or to electronically deliver such shares of Common Stock) as required pursuant to the terms hereof. Notwithstanding
anything herein to the contrary, with respect to any given Notice Failure and/or Delivery Failure, this Section 5(e) shall not
apply to the applicable Buyer the extent the Company has already paid such amounts in full to such Buyer with respect to such
Notice Failure and/or Delivery Failure, as applicable, pursuant to the analogous sections of the Note or Warrant, as applicable,
held by such Buyer.

Fast Automated Securities Transfer Program.

    -34-

     

    

 

9. MISCELLANEOUS.

 

(a) Governing
Law; Jurisdiction; Jury Trial. All questions concerning the construction, validity,
enforcement and interpretation of this Agreement shall be governed by the internal laws of the State of New York, without giving
effect to any choice of law or conflict of law provision or rule (whether of the State of New York or any other jurisdictions)
that would cause the application of the laws of any jurisdictions other than the State of New York. The Company 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 under any of the other Transaction Documents or with any
transaction contemplated hereby or thereby, and hereby irrevocably waives, and agrees not to assert in any suit, action or proceeding,
any claim that it is not personally subject to the jurisdiction of any such court, that such suit, action or proceeding is brought
in an inconvenient forum or that the venue of such suit, action or proceeding is improper. Each party hereby irrevocably waives
personal service of process and consents to process being served in any such suit, action or proceeding by mailing a copy thereof
to such party at the address for such 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 manner permitted by law. Nothing contained herein shall be deemed or operate to preclude any Buyer from bringing
suit or taking other legal action against the Company in any other jurisdiction to collect on the Company’s obligations
to such Buyer or to enforce a judgment or other court ruling in favor of such Buyer. EACH PARTY HEREBY IRREVOCABLY WAIVES ANY
RIGHT IT MAY HAVE TO, AND AGREES NOT TO REQUEST, A JURY TRIAL FOR THE ADJUDICATION OF ANY DISPUTE HEREUNDER OR UNDER ANY OTHER
TRANSACTION DOCUMENT OR IN CONNECTION WITH OR ARISING OUT OF THIS AGREEMENT, ANY OTHER TRANSACTION DOCUMENT OR ANY TRANSACTION
CONTEMPLATED HEREBY OR THEREBY.

 

(b) Counterparts.
This Agreement may be executed in two or more identical counterparts, all of which shall be considered one and the same agreement
and shall become effective when counterparts have been signed by each party and delivered to the other party. In the event that
any signature is delivered by facsimile transmission or by an e-mail which contains a portable document format (.pdf) file of
an executed signature page, such signature page 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 signature page were an original thereof.

 

    -35-

     

    

 

(c) Headings;
Gender. The headings of this Agreement are for convenience of reference and shall
not form part of, or affect the interpretation of, this Agreement. Unless the context clearly indicates otherwise, each pronoun
herein shall be deemed to include the masculine, feminine, neuter, singular and plural forms thereof. The terms “including,”
“includes,” “include” and words of like import shall be construed broadly as if followed by the words
“without limitation.” The terms “herein,” “hereunder,” “hereof” and words of like
import refer to this entire Agreement instead of just the provision in which they are found.

 

(d) Severability;
Maximum Payment Amounts. If any provision of this Agreement is prohibited by law
or otherwise determined to be invalid or unenforceable by a court of competent jurisdiction, the provision that would otherwise
be prohibited, invalid or unenforceable shall be deemed amended to apply to the broadest extent that it would be valid and enforceable,
and the invalidity or unenforceability of such provision shall not affect the validity of the remaining provisions of this Agreement
so long as this Agreement as so modified continues to express, without material change, the original intentions of the parties
as to the subject matter hereof and the prohibited nature, invalidity or unenforceability of the provision(s) in question does
not substantially impair the respective expectations or reciprocal obligations of the parties or the practical realization of
the benefits that would otherwise be conferred upon the parties. The parties will endeavor in good faith negotiations to replace
the prohibited, invalid or unenforceable provision(s) with a valid provision(s), the effect of which comes as close as possible
to that of the prohibited, invalid or unenforceable provision(s). Notwithstanding anything to the contrary contained in this Agreement
or any other Transaction Document (and without implication that the following is required or applicable), it is the intention
of the parties that in no event shall amounts and value paid by the Company and/or any of its Subsidiaries (as the case may be),
or payable to or received by any of the Buyers, under the Transaction Documents (including without limitation, any amounts that
would be characterized as “interest” under applicable law) exceed amounts permitted under any applicable law. Accordingly,
if any obligation to pay, payment made to any Buyer, or collection by any Buyer pursuant the Transaction Documents is finally
judicially determined to be contrary to any such applicable law, such obligation to pay, payment or collection shall be deemed
to have been made by mutual mistake of such Buyer, the Company and its Subsidiaries and such amount shall be deemed to have been
adjusted with retroactive effect to the maximum amount or rate of interest, as the case may be, as would not be so prohibited
by the applicable law. Such adjustment shall be effected, to the extent necessary, by reducing or refunding, at the option of
such Buyer, the amount of interest or any other amounts which would constitute unlawful amounts required to be paid or actually
paid to such Buyer under the Transaction Documents. For greater certainty, to the extent that any interest, charges, fees, expenses
or other amounts required to be paid to or received by such Buyer under any of the Transaction Documents or related thereto are
held to be within the meaning of “interest” or another applicable term to otherwise be violative of applicable law,
such amounts shall be pro-rated over the period of time to which they relate.

 

    -36-

     

    

 

(e) Entire
Agreement; Amendments. This Agreement, the other Transaction Documents and the
schedules and exhibits attached hereto and thereto and the instruments referenced herein and therein supersede all other prior
oral or written agreements between the Buyers, the Company, its Subsidiaries, their affiliates and Persons acting on their behalf,
including, without limitation, any transactions by any Buyer with respect to Common Stock or the Securities, and the other matters
contained herein and therein, and this Agreement, the other Transaction Documents, the schedules and exhibits attached hereto
and thereto and the instruments referenced herein and therein contain the entire understanding of the parties solely with respect
to the matters covered herein and therein; provided, however, nothing contained in this Agreement or any other Transaction Document
shall (or shall be deemed to) (i) have any effect on any agreements any Buyer has entered into with, or any instruments any Buyer
has received from, the Company or any of its Subsidiaries prior to the date hereof with respect to any prior investment made by
such Buyer in the Company or (ii) waive, alter, modify or amend in any respect any obligations of the Company or any of its Subsidiaries,
or any rights of or benefits to any Buyer or any other Person, in any agreement entered into prior to the date hereof between
or among the Company and/or any of its Subsidiaries and any Buyer, or any instruments any Buyer received from the Company and/or
any of its Subsidiaries prior to the date hereof, and all such agreements and instruments shall continue in full force and effect.
Except as specifically set forth herein or therein, neither the Company nor any Buyer makes any representation, warranty, covenant
or undertaking with respect to such matters. For clarification purposes, the Recitals are part of this Agreement. No provision
of this Agreement may be amended other than by an instrument in writing signed by the Company and the Required Holders (as defined
below), and any amendment to any provision of this Agreement made in conformity with the provisions of this Section 9(e)
shall be binding on all Buyers and holders of Securities, as applicable; provided that no such amendment shall be effective
to the extent that it (A) applies to less than all of the holders of the Securities then outstanding or (B) imposes any obligation
or liability on any Buyer without such Buyer’s prior written consent (which may be granted or withheld in such Buyer’s
sole discretion). No waiver shall be effective unless it is in writing and signed by an authorized representative of the waiving
party, provided that the Required Holders may waive any provision of this Agreement, and any waiver of any provision of
this Agreement made in conformity with the provisions of this Section 9(e) shall be binding on all Buyers and holders of
Securities, as applicable, provided that no such waiver shall be effective to the extent that it (1) applies to less than
all of the holders of the Securities then outstanding (unless a party gives a waiver as to itself only) or (2) imposes any obligation
or liability on any Buyer without such Buyer’s prior written consent (which may be granted or withheld in such Buyer’s
sole discretion). The Company has not, directly or indirectly, made any agreements with any Buyers relating to the terms or conditions
of the transactions contemplated by the Transaction Documents except as set forth in the Transaction Documents. Without limiting
the foregoing, the Company confirms that, except as set forth in this Agreement, no Buyer has made any commitment or promise or
has any other obligation to provide any financing to the Company, any Subsidiary or otherwise. As a material inducement for each
Buyer to enter into this Agreement, the Company expressly acknowledges and agrees that (x) no due diligence or other investigation
or inquiry conducted by a Buyer, any of its advisors or any of its representatives shall affect such Buyer’s right to rely
on, or shall modify or qualify in any manner or be an exception to any of, the Company’s representations and warranties
contained in this Agreement or any other Transaction Document and (y) unless a provision of this Agreement or any other Transaction
Document is expressly preceded by the phrase “except as disclosed in the SEC Documents,” nothing contained in any
of the SEC Documents shall affect such Buyer’s right to rely on, or shall modify or qualify in any manner or be an exception
to any of, the Company’s representations and warranties contained in this Agreement or any other Transaction Document. “Required
Holders” means (I) prior to the Closing Date, each Buyer entitled to purchase Notes at the Closing and (II) on or after
the Closing Date, holders of a majority of the Registrable Securities as of such time (excluding any Registrable Securities held
by the Company or any of its Subsidiaries as of such time) issued or issuable hereunder or pursuant to the Notes and/or the Warrants.

parties and their respective successors and assigns, including any purchasers of any of the Notes and Warrants. The Company shall
not assign this Agreement or any rights or obligations hereunder without the prior written consent of the Required Holders, including,
without limitation, by way of a Fundamental Transaction (as defined in the Warrants) (unless the Company is in compliance with
the applicable provisions governing Fundamental Transactions set forth in the Warrants) or a Fundamental Transaction (as defined
in the Notes) (unless the Company is in compliance with the applicable provisions governing Fundamental Transactions set forth
in the Notes). A Buyer may assign some or all of its rights hereunder in connection with any transfer of any of its Securities
without the consent of the Company, in which event such assignee shall be deemed to be a Buyer hereunder with respect to such
assigned rights.

 

(h) No Third
Party Beneficiaries. This Agreement is intended for the benefit of the parties
hereto and their respective permitted successors and assigns, and is not for the benefit of, nor may any provision hereof be enforced
by, any other Person, other than the Indemnitees referred to in Section 9(k).

 

(i) Survival.
The representations, warranties, agreements and covenants shall survive the Closing. Each Buyer shall be responsible only for
its own representations, warranties, agreements and covenants hereunder.

 

(j) Further
Assurances. Each party shall do and perform, or cause to be done and performed,
all such further acts and things, and shall execute and deliver all such other agreements, certificates, instruments and documents,
as any other party may reasonably request in order to carry out the intent and accomplish the purposes of this Agreement and the
consummation of the transactions contemplated hereby.

(k) Indemnification.
In consideration of each Buyer’s execution and delivery of the Transaction Documents and acquiring the Securities thereunder
and in addition to all of the Company’s other obligations under the Transaction Documents, the Company shall defend, protect,
indemnify and hold harmless each Buyer and each holder of any Securities and all of their stockholders, partners, members, officers,
directors, employees and direct or indirect investors and any of the foregoing Persons’ agents or other representatives
(including, without limitation, those retained in connection with the transactions contemplated by this Agreement) (collectively,
the “Indemnitees”) from and against any and all actions, causes of action, suits, claims, losses, costs, penalties,
fees, liabilities and damages, and expenses in connection therewith (irrespective of whether any such Indemnitee is a party to
the action for which indemnification hereunder is sought), and including reasonable attorneys’ fees and disbursements (the
“Indemnified Liabilities”), incurred by any Indemnitee as a result of, or arising out of, or relating to (i)
any misrepresentation or breach of any representation or warranty made by the Company or any Subsidiary in any of the Transaction
Documents, (ii) any breach of any covenant, agreement or obligation of the Company or any Subsidiary contained in any of the Transaction
Documents or (iii) any cause of action, suit, proceeding or claim brought or made against such Indemnitee by a third party (including
for these purposes a derivative action brought on behalf of the Company or any Subsidiary) or which otherwise involves such Indemnitee
that arises out of or results from (A) the execution, delivery, performance or enforcement of any of the Transaction Documents,
(B) any transaction financed or to be financed in whole or in part, directly or indirectly, with the proceeds of the issuance
of the Securities, (C) any disclosure properly made by such Buyer pursuant to Section 4(i), or (D) the status of such Buyer
or holder of the Securities either as an investor in the Company pursuant to the transactions contemplated by the Transaction
Documents or as a party to this Agreement (including, without limitation, as a party in interest or otherwise in any action or
proceeding for injunctive or other equitable relief). To the extent that the foregoing undertaking by the Company may be unenforceable
for any reason, the Company shall make the maximum contribution to the payment and satisfaction of each of the Indemnified Liabilities
which is permissible under applicable law. Except as otherwise set forth herein, the mechanics and procedures with respect to
the rights and obligations under this Section 9(k) shall be the same as those set forth in Section 6 of the Registration
Rights Agreement.

 

(l) Construction.
The language used in this Agreement will be deemed to be the language chosen by the parties to express their mutual intent, and
no rules of strict construction will be applied against any party. No specific representation or warranty shall limit the generality
or applicability of a more general representation or warranty. Each and every reference to share prices, shares of Common Stock
and any other numbers in this Agreement that relate to the Common Stock shall be automatically adjusted for any stock splits,
stock dividends, stock combinations, recapitalizations or other similar transactions that occur with respect to the Common Stock
after the date of this Agreement. Notwithstanding anything in this Agreement to the contrary, for the avoidance of doubt, nothing
contained herein shall constitute a representation or warranty against, or a prohibition of, any actions with respect to the borrowing
of, arrangement to borrow, identification of the availability of, and/or securing of, securities of the Company in order for such
Buyer (or its broker or other financial representative) to effect short sales or similar transactions in the future.

(m) Remedies.
Each Buyer and in the event of assignment by Buyer of its rights and obligations hereunder, each holder of Securities, shall have
all rights and remedies set forth in the Transaction Documents and all rights and remedies which such holders have been granted
at any time under any other agreement or contract and all of the rights which such holders have under any law. Any Person having
any rights under any provision of this Agreement shall be entitled to enforce such rights specifically (without posting a bond
or other security), to recover damages by reason of any breach of any provision of this Agreement and to exercise all other rights
granted by law. Furthermore, the Company recognizes that in the event that it or any Subsidiary fails to perform, observe, or
discharge any or all of its or such Subsidiary’s (as the case may be) obligations under the Transaction Documents, any remedy
at law would inadequate relief to the Buyers. The Company therefore agrees that the Buyers shall be entitled to specific performance
and/or temporary, preliminary and permanent injunctive or other equitable relief from any court of competent jurisdiction in any
such case without the necessity of proving actual damages and without posting a bond or other security. The remedies provided
in this Agreement and the other Transaction Documents shall be cumulative and in addition to all other remedies available under
this Agreement and the other Transaction Documents, at law or in equity (including a decree of specific performance and/or other
injunctive relief).

 

(n) Withdrawal
Right. Notwithstanding anything to the contrary contained in (and without limiting
any similar provisions of) the Transaction Documents, whenever any Buyer exercises a right, election, demand or option under a
Transaction Document and the Company or any Subsidiary does not timely perform its related obligations within the periods therein
provided, then such Buyer may rescind or withdraw, in its sole discretion from time to time upon written notice to the Company
or such Subsidiary (as the case may be), any relevant notice, demand or election in whole or in part without prejudice to its
future actions and rights.

 

(o) Payment
Set Aside; Currency. To the extent that the Company makes a payment or payments
to any Buyer hereunder or pursuant to any of the other Transaction Documents or any of the Buyers enforce or exercise their rights
hereunder or 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, foreign, 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. Unless otherwise expressly
indicated, all dollar amounts referred to in this Agreement and the other Transaction Documents are in United States Dollars (“U.S.
Dollars”), and all amounts owing under this Agreement and all other Transaction Documents shall be paid in U.S. Dollars.
All amounts denominated in other currencies (if any) shall be converted into the U.S. Dollar equivalent amount in accordance with
the Exchange Rate on the date of calculation. “Exchange Rate” means, in relation to any amount of currency
to be converted into U.S. Dollars pursuant to this Agreement, the U.S. Dollar exchange rate as published in the Wall Street Journal
on the relevant date of calculation.

(p) Judgment
Currency.

 

(i) If
for the purpose of obtaining or enforcing judgment against the Company in connection with this Agreement or any other Transaction
Document in any court in any jurisdiction it becomes necessary to convert into any other currency (such other currency being hereinafter
in this Section 9(p) referred to as the “Judgment Currency”) an amount due in US Dollars under this Agreement,
the conversion shall be made at the Exchange Rate prevailing on the Trading Day immediately preceding:

 

(1) the
date actual payment of the amount due, in the case of any proceeding in the courts of New York or in the courts of any other jurisdiction
that will give effect to such conversion being made on such date: or

 

(2) the
date on which the foreign court determines, in the case of any proceeding in the courts of any other jurisdiction (the date as
of which such conversion is made pursuant to this Section 9(p)(i)(2) being hereinafter referred to as the “Judgment
Conversion Date”).

 

(ii) If
in the case of any proceeding in the court of any jurisdiction referred to in Section 9(p)(i)(2) above, there is a change
in the Exchange Rate prevailing between the Judgment Conversion Date and the date of actual payment of the amount due, the applicable
party shall pay such adjusted amount as may be necessary to ensure that the amount paid in the Judgment Currency, when converted
at the Exchange Rate prevailing on the date of payment, will produce the amount of US Dollars which could have been purchased with
the amount of Judgment Currency stipulated in the judgment or judicial order at the Exchange Rate prevailing on the Judgment Conversion
Date.

 

(iii) Any
amount due from the Company under this provision shall be due as a separate debt and shall not be affected by judgment being obtained
for any other amounts due under or in respect of this Agreement or any other Transaction Document.

 

(q) Independent
Nature of Buyers’ Obligations and Rights. The obligations of each Buyer under
the Transaction Documents are several and not joint with the obligations of any other Buyer, and no Buyer shall be responsible
in any way for the performance of the obligations of any other Buyer under any Transaction Document. Nothing contained herein
or in any other Transaction Document, and no action taken by any Buyer pursuant hereto or thereto, shall be deemed to constitute
the Buyers as, and the Company acknowledges that the Buyers do not so constitute, a partnership, an association, a joint venture
or any other kind of group or entity, or create a presumption that the Buyers are in any way acting in concert or as a group or
entity, and the Company shall not assert any such claim with respect to such obligations or the transactions contemplated by the
Transaction Documents or any matters, and the Company acknowledges that the Buyers are not acting in concert or as a group, and
the Company shall not assert any such claim, with respect to such obligations or the transactions contemplated by the Transaction
Documents. The decision of each Buyer to purchase Securities pursuant to the Transaction Documents has been made by such Buyer
independently of any other Buyer. Each Buyer acknowledges that no other Buyer has acted as agent for such Buyer in connection
with such Buyer making its investment hereunder and that no other Buyer will be acting as agent of such Buyer in connection with
monitoring such Buyer’s investment in the Securities or enforcing its rights under the Transaction Documents. The Company
and each Buyer confirms that each Buyer has independently participated with the Company and its Subsidiaries in the negotiation
of the transaction contemplated hereby with the advice of its own counsel and advisors. Each Buyer shall be entitled to independently
protect and enforce its rights, including, without limitation, the rights arising out of this Agreement or out of any other Transaction
Documents, and it shall not be necessary for any other Buyer to be joined as an additional party in any proceeding for such purpose.
The use of a single agreement to effectuate the purchase and sale of the Securities contemplated hereby was solely in the control
of the Company, not the action or decision of any Buyer, and was done solely for the convenience of the Company and its Subsidiaries
and not because it was required or requested to do so by any Buyer. It is expressly understood and agreed that each provision
contained in this Agreement and in each other Transaction Document is between the Company, each Subsidiary and a Buyer, solely,
and not between the Company, its Subsidiaries and the Buyers collectively and not between and among the Buyers.
