PURCHASE AND SALE


 


2.1 Closings.


 


(a) Initial
Closing. On the Initial Closing Date, upon the terms and subject to the conditions set forth herein, substantially concurrent with
the execution and delivery of this Agreement by the parties hereto, the Company agrees to sell, and the Purchasers, severally and not
jointly, agree to purchase, (i) an aggregate of $12,500,000 of Principal Amount of Registered Advance Notes for an aggregate purchase
price of $11,250,000 and (ii) (A) an aggregate of $2,500,000 of Principal Amount of Private Placement Advance Notes and (B) the Warrants,
for an aggregate purchase price of $2,250,000, in each case in an aggregate Principal Amount, and for Warrants exercisable for such number
of shares of Common Stock, for each Purchaser, as are set forth on the signature page hereto executed by such Purchaser. Each Purchaser
shall deliver to the Company, via wire transfer, immediately available funds equal to such Purchaser’s Subscription Amount as set
forth on the signature page hereto executed by such Purchaser, and the Company shall deliver to each Purchaser its respective Closing
Advance Notes and a Warrant, as determined pursuant to Section 2.2(a), and the Company and each Purchaser shall deliver the other items
set forth in Section 2.2 deliverable at the Closing. Within two days of the satisfaction (or, to the extent permitted by applicable law,
waiver) of the covenants and conditions set forth in Sections 2.2 and 2.3, the Closing shall occur at the offices of Nason, Yeager, Gerson,
Harris & Fumero, P.A. or such other location, as the parties shall mutually agree.


 


(b) Monthly
Closings. Provided that the Equity Conditions are then met and less than an aggregate principal amount of $2,000,000 of Advance Notes
held by the Purchasers is then outstanding, beginning on the Prepaid-Tranche Commencement date and ending 18 months after the Initial
Closing, the Company, at its discretion, may request that the Initial Collateral Agent (and not any other Purchaser) purchase a Prepaid-Tranche
(not to exceed the Monthly Funded Amount Limit) by providing written notice of such request solely to the Initial Collateral Agent (the
“Request”) and to the Placement Agent (or, if the Placement Agent is unable to act, another broker-dealer registered
as such under the Exchange Act). The closing of each Prepaid-Tranche shall take place on or before the fifth Business Day following the
date of such Request but in no event less than 30 days after the Initial Collateral Agent has last funded a Prepaid-Tranche, or such earlier
date as may be agreed by the Initial Collateral Agent and the Company (the “Prepaid-Tranche Closing Date”). On each
Prepaid-Tranche Closing Date, the Initial Collateral Agent shall pay the Subscription Amount for the Prepaid-Tranche set forth in such
Request in immediately available funds to an account designated by the Company in writing and transmit notification to the Company that
such funds transfer has been requested. In addition to the Company exercising its discretion to request any Prepaid-Tranche, subject to
the satisfaction of the Equity Conditions at such time, the Initial Collateral Agent shall have the option (a “Purchaser Advance
Note Option”) to require the Company to accept a monthly Prepaid-Tranche in an amount limited to $1,000,000. The procedure in
this Section 2.1(b) shall apply to the exercise of any such option by the Initial Collateral Agent, which shall be exercised on not more
than two occasions by the Initial Collateral Agent with the Initial Collateral Agent required to give notice to the Company. The Company
acknowledges and agrees that no Purchaser other than the Initial Collateral Agent shall have any obligation to purchase any of the Prepaid-Tranches
nor shall any other Purchaser have any liability to the Company for any breach or failure of the Initial Collateral Agent to perform hereunder.

Each of the Company and the Subsidiaries is duly qualified to conduct business and is in good standing as a foreign corporation or other
entity in each jurisdiction in which the nature of the business conducted or property owned by it makes such qualification necessary,

on the results of operations, assets, business, prospects or condition (financial or otherwise) of the Company and the Subsidiaries, taken

Person (other than the Purchasers) and will not result in a right of any holder of Company securities to adjust the exercise, conversion,
exchange or reset price under any of such securities. There are no outstanding securities or instruments of the Company or any Subsidiary
that contain any redemption or similar provisions, and there are no contracts, commitments, understandings or arrangements by which the

from any Trading Market on which the Common Stock is or has been listed or quoted to the effect that the Company is not in compliance

current in payment of the fees to DTC (or such other established clearing corporation) in connection with such electronic transfer.

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


 






    25


     


    

 


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


 


(aa) No Integrated
Offering. Assuming the accuracy of each Purchaser’s representations and warranties set forth in Section 3.2, neither
the Company, nor any of its Affiliates, nor any Person acting on its or their behalf has, directly or indirectly, made any offers or sales
of any security or solicited any offers to buy any security, under circumstances that would cause this offering of the Securities to be
integrated with prior offerings by the Company for purposes of (i) the Securities Act, which would require the registration of the $2.5M
Closing Advance Notes or the Warrants under the Securities Act, or (ii) any applicable shareholder approval provisions of any Trading Market
on which any of the securities of the Company are listed or designated.


 


(bb) Solvency.

that will be required to be paid on or in respect of the Company’s existing debts and other liabilities (including known contingent
liabilities) as they mature, (ii) the Company’s assets do not constitute unreasonably small capital to carry on its business as
now conducted and as proposed to be conducted including its capital needs taking into account the particular capital requirements of the
business conducted by the Company, consolidated and projected capital requirements and capital availability thereof, and (iii) the current
cash flow of the Company, together with the proceeds the Company would receive, were it to liquidate all of its assets, after taking into
account all anticipated uses of the cash, would be sufficient to pay all amounts on or in respect of its liabilities when such amounts
are required to be paid. The Company does not intend to incur debts beyond its ability to pay such debts as they mature (taking into account
the timing and amounts of cash to be payable on or in respect of its debt). The Company has no knowledge of any facts or circumstances,
which lead it to believe that it will file for reorganization or liquidation under the bankruptcy or reorganization laws of any jurisdiction
within one year from each Closing Date. Schedule 3.1(bb) sets forth, as of the date hereof, all outstanding secured and unsecured
Indebtedness of the Company or any Subsidiary, or for which the Company or any Subsidiary has commitments. For the purposes of this Agreement,
“Indebtedness” means (x) any liabilities for borrowed money or amounts owed in excess of $100,000 (other than trade
accounts payable incurred in the ordinary course of business), (y) all guaranties, endorsements and other contingent obligations in respect
of Indebtedness of others, whether or not the same are or should be reflected in the Company’s consolidated balance sheet (or the
notes thereto), except guaranties by endorsement of negotiable instruments for deposit or collection or similar transactions in the ordinary
course of business; and (z) the present value of any lease payments in excess of $100,000 due under leases required to be capitalized

and (C) has set aside on its books provision reasonably adequate for the payment of all material taxes for periods subsequent to the periods

any jurisdiction, and the officers of the Company or of any Subsidiary know of no basis for any such claim.

Advance Notes), is senior to the Closing Advance Notes or the Prepaid-Tranches in right of payment, whether with respect to interest or
upon liquidation or dissolution, or otherwise.

hold the Securities for any specified term, (ii) past or future open market or other transactions by any Purchaser, specifically including,
without limitation, short sales or “derivative” transactions, before or after the closing of this or future private placement
transactions, may negatively impact the market price of the Company’s publicly-traded securities, (iii) any Purchaser, and counter-parties
in “derivative” transactions to which any such Purchaser is a party, directly or indirectly, may presently have a “short”
position in the Common Stock and (iv) each Purchaser shall not be deemed to have any affiliation with or control over any arm’s
length counter-party in any “derivative” transaction. The Company further understands and acknowledges
that (y) one or more Purchasers may engage in hedging activities at various times during the period that the Securities are outstanding,
including, without limitation, during the periods that the value of the Underlying Shares deliverable with respect to Securities are
being determined, and (z) such hedging activities (if any) could reduce the value of the existing stockholders’ equity interests
in the Company at and after the time that the hedging activities are being conducted. The Company acknowledges that such aforementioned
hedging activities do not constitute a breach of any of the Transaction Documents.

3.2 Representations and Warranties
of the Purchasers. Each Purchaser (or, with respect to any Monthly Closing, the Initial Collateral Agent), for itself and for no other
Purchaser, hereby represents and warrants as of the date hereof and as of each applicable Closing Date to the Company as follows (unless
as of a specific date therein, in which case they shall be accurate as of such date):


 


(a) Organization;
Authority. Such Purchaser is either an individual or an entity duly incorporated or formed, validly existing and in good standing
under the laws of the jurisdiction of its incorporation or formation with full right, corporate, partnership, limited liability company
or similar power and authority to enter into and to consummate the transactions contemplated by the Transaction Documents and otherwise
to carry out its obligations hereunder and thereunder. The execution and delivery of the Transaction Documents and performance by such
Purchaser of the transactions contemplated by the Transaction Documents have been duly authorized by all necessary corporate, partnership,
limited liability company or similar action, as applicable, on the part of such Purchaser. Each Transaction Document to which it is a
party has been duly executed by such Purchaser, and when delivered by such Purchaser in accordance with the terms hereof, will constitute
the valid and legally binding obligation of such Purchaser, enforceable against it in accordance with its terms, except (i) as limited
by general equitable principles and applicable bankruptcy, insolvency, reorganization, moratorium and other laws of general application
affecting enforcement of creditors’ rights generally, (ii) as limited by laws relating to the availability of specific performance,
injunctive relief or other equitable remedies and (iii) insofar as indemnification and contribution provisions may be limited by applicable
law.


 


(b) Own Account.
With respect to the $2.5M Closing Advance Notes, the Warrants and the Underlying Shares thereof, such Purchaser understands that such Securities
are “restricted securities” and have not been registered under the Securities Act or any applicable state securities law and
is acquiring such Securities as principal for its own account and not with a view to or for distributing or reselling such Securities
or any part thereof in violation of the Securities Act or any applicable state securities law, has no present intention of distributing
any of such Securities in violation of the Securities Act or any applicable state securities law and has no direct or indirect arrangement
or understandings with any other Persons to distribute or regarding the distribution of such Securities in violation of the Securities
Act or any applicable state securities law (this representation and warranty not limiting such Purchaser’s right to sell such Securities
in compliance with applicable federal and state securities laws). Such Purchaser is acquiring such Securities hereunder in the ordinary
course of its business.


 






    30


     


    

 


(c) Purchaser
Status. At the time such Purchaser was offered the Securities, it was, and as of the date hereof it is, and on each date on which
it acquires any Prepaid-Tranche (solely as to the Initial Collateral Agent) or other Advance Note, exercises any Warrants or converts
its Advance Note or, solely as to the Initial Collateral Agent, any Prepaid-Tranche, it will be either: (i) an “accredited investor”
as defined in Rule 501(a)(1), (a)(2), (a)(3), (a)(7), (a)(8), (a)(9), (a)(12), or (a)(13) under the Securities Act or (ii) a “qualified
institutional buyer” as defined in Rule 144A(a) under the Securities Act.


 


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


 


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


 


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


 


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

ARTICLE IV.


OTHER AGREEMENTS OF THE PARTIES


 


4.1 Transfer Restrictions.


 


(a) The Securities
may only be disposed of in compliance with state and federal securities laws. In connection with any transfer of the Private Placement
Advance Notes, the Warrants or any Underlying Shares thereof (collectively, the “Private Placement Securities”) other
than pursuant to an effective registration statement or Rule 144, to the Company or to an Affiliate of a Purchaser or in connection with
a pledge as contemplated in Section 4.1(b), the Company may require the transferor thereof to provide to the Company an opinion of counsel
selected by the transferor and reasonably acceptable to the Company, the form and substance of which opinion shall be reasonably satisfactory
to the Company, to the effect that such transfer does not require registration of such transferred Securities under the Securities Act.
As a condition of transfer, any such transferee shall agree in writing to be bound by the terms of this Agreement and shall have the rights
and obligations of a Purchaser under this Agreement.


 


(b) With respect
to the Private Placement Securities, the Purchasers agree to the imprinting, so long as is required by this Section 4.1, of a legend on
any of the Private Placement Securities in the following form:


 


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


 


Such legend requirement shall
not be construed to mean an Event of Default has not occurred, to the extent otherwise applicable. No legends shall be placed on any of
the Registered Advance Notes or Conversion Shares underlying the Registered Advance Notes.


 


The Company acknowledges and
agrees that a Purchaser may from time to time pledge pursuant to a bona fide margin agreement with a registered broker-dealer or grant
a security interest in some or all of the Securities to a financial institution that is an “accredited investor” as defined
in Rule 501(a) under the Securities Act and, if required under the terms of such arrangement, such Purchaser may transfer pledged or secured
Securities to the pledgees or secured parties. Such a transfer would be subject to compliance with the terms of this Section 4.1. At the
appropriate Purchaser’s expense, the Company will execute and deliver such reasonable documentation as a pledgee or secured party
of Securities may reasonably request in connection with a pledge or transfer of the Securities.


 






    32


     


    

 


(c) Certificates
or book-entry positions evidencing the Underlying Shares for any Private Placement Securities shall not contain any legend (including
the legend set forth in Section 4.1(b) hereof): (i) while a registration statement covering the resale of such security is effective under
the Securities Act; (ii) if such Underlying Shares are eligible to be sold, assigned or transferred under Rule 144, when available, without
volume or manner-of-sale restrictions or current public information requirements under Rule 144 (for the Warrants, assuming cashless exercise
of the Warrants which cashless exercise, for the avoidance of doubt, shall be available only in the event that a registration statement
covering the resale of Underlying Shares is not available) (provided that a Purchaser provides the Company with reasonable and customary
assurances that such Securities are eligible for sale, assignment or transfer under Rule 144 which shall not include an opinion of a Purchaser’s
counsel), or (iii) if such legend is not required (other than under Rule 144) under applicable requirements of the Securities Act (including
judicial interpretations and pronouncements issued by the staff of the Commission). For the avoidance of doubt, (A) the Company shall
pay all costs associated with such opinions and counsel to the Company, (B) counsel to the Company shall provide all opinions with respect
to any resales pursuant to and in compliance with Rule 144, subject to receipt of customary representations and warranties of the holders
of any Securities or the brokers thereof as may be reasonably requested by such counsel to the Company, on which such counsel and the
Transfer Agent may conclusively rely, and (C) the Company shall provide confirmation to the Transfer Agent that all such opinions (subject
to compliance by the holders of any applicable Securities with the foregoing clause (B)) are acceptable. If all or any portion of a Registered
Advance Note or, solely as to the Initial Collateral Agent, Prepaid-Tranche is converted at a time when there is an effective Form S-3
or registration statement to cover the resale of the Underlying Shares with respect to such Registered Advance Note or, solely as to the
Initial Collateral Agent, Prepaid-Tranche, or if such Underlying Shares may be sold under Rule 144 without the requirement for the Company
to be in compliance with the current public information requirements of Rule 144(c) and without volume or manner of sale restrictions
or if such legend is not otherwise required under applicable requirements of the Securities Act (including Sections 4(a)(1) or 4(a)(7),
judicial interpretations and pronouncements issued by the staff of the SEC including what is known as Section 4(a)(11⁄2)) then such
Underlying Shares shall be issued free of all legends. For avoidance of doubt, the Company agrees that after the requisite holding period
to comply with Rule 144 after which any applicable securities may be sold under Rule 144 without the requirement for the Company to be
in compliance with the current public information requirements of Rule 144(c) and without volume or manner of sale restrictions, the legend
may be removed under Rule 144 of the Securities Act, assuming the holder satisfies the requirements of Rule 144. The Company agrees that
at such time as such legend is no longer required under this Section 4.1(c), it will, no later than the earlier of (1) two Trading Days
and (2) the number of Trading Days comprising the Standard Settlement Period (as defined below) following the delivery by any Purchaser
(x) to the Company of a request to remove any applicable restrictive legend from any applicable securities or for the issuance of any
securities without a restrictive legend and (y) to the Company or the Transfer Agent of a certificate (or stock power if issued in book
entry form) representing Shares or Warrant Shares, as applicable, issued without a restrictive legend (such date, the “Legend
Removal Date”), deliver or cause to be delivered to such Purchaser a certificate representing such shares (or evidence of issuance
in book entry form of such shares) that is free from all restrictive and other legends. The Company may not make any notation on its records
or give instructions to the Transfer Agent that enlarge the restrictions on transfer set forth in this Section 4. Certificates, if
any, for Underlying Shares subject to legend removal hereunder shall be transmitted by the Transfer Agent to such Purchaser by crediting
the account of the Purchaser’s prime broker with the DTC System as directed by the Purchaser. As used herein, “Standard
Settlement Period” means the standard settlement period, expressed in a number of Trading Days, on the Company’s Principal
Market with respect to the Common Stock as in effect on the date of delivery of a certificate (or evidence of issuance in book-entry form)
representing any applicable Underlying Shares issued with a restrictive legend.


 






    33


     


    

 


(d) In addition
to such Purchaser’s other available remedies, the Company shall pay to a Purchaser, in cash, (i) as partial liquidated damages and
not as a penalty, for each $1,000 of Underlying Shares (based on the VWAP of the Common Stock on the date such Securities are submitted
to the Transfer Agent) delivered for removal of the restrictive legend and subject to the Purchaser’s compliance with any applicable
provisions of Section 4.1(c), $5 per Trading Day (increasing to $10 per Trading Day five Trading Days after such damages have begun to
accrue) for each Trading Day after the Legend Removal Date until such certificate is delivered without a legend, and (ii) if the Company
fails to (A) issue and deliver (or cause to be delivered) to a Purchaser by the Legend Removal Date a certificate representing (or evidence
of the book-entry issuance of) the Securities so delivered to the Company by such Purchaser that is free from all restrictive and other
legends and (B) if after the Legend Removal Date, such Purchaser purchases (in an open market transaction or otherwise) shares of Common
Stock to deliver in satisfaction of a sale by such Purchaser of all or any portion of the number of shares of Common Stock, or a sale
of a number of shares of Common Stock equal to all or any portion of the number of shares of Common Stock that such Purchaser anticipated
receiving from the Company without any restrictive legend (a “Buy-In”), then the Company shall (1) pay in cash to the
Purchaser the amount, if any, by which (x) the Purchaser’s total purchase price (including brokerage commissions, if any) for the
shares of Common Stock so purchased exceeds (y) the amount obtained by multiplying (i) the number of Underlying Shares that the Company
was required to remove restrictive legends from in connection with the transfer at issue, times (ii) the price at which the sell order
giving rise to such purchase obligation was executed, and (2) cause the Transfer Agent to remove the restrictive and other legends from
such Underlying Shares as promptly as reasonably practicable. For example, if the applicable Purchaser purchases Common Stock having a
total purchase price of $11,000 to cover a Buy-In with respect to an attempted sale of Underlying Shares with an aggregate sale price
giving rise to such purchase obligation of $10,000, under clause (1) of the immediately preceding sentence the Company shall be required
to pay such Purchaser $1,000. The applicable Purchaser shall provide the Company written notice indicating the amounts payable to such
Purchaser in respect of the Buy-In and, upon request of the Company, evidence of the amount of such loss.


 


(e) Each Purchaser,
severally and not jointly with the other Purchasers, agrees with the Company that such Purchaser will sell any Securities pursuant to
either the registration requirements of the Securities Act, including any applicable prospectus delivery requirements, or an exemption
therefrom, and that if Securities are sold pursuant to a then-effective registration statement, they will be sold in compliance with the
plan of distribution set forth therein, and acknowledges that the removal of the restrictive legend from certificates (or book-entry positions)
representing Private Placement Securities as set forth in this Section 4.1 is predicated upon the Company’s reliance upon this understanding.


 


4.2 Acknowledgment of Dilution;
Volume Limitation on Sales.


 


(a) The Company
acknowledges that the issuance of the Securities may result in dilution of the outstanding shares of Common Stock, which dilution may
be substantial under certain market conditions. The Company further acknowledges that its obligations under the Transaction Documents,
including, without limitation, its obligation to issue the Underlying Shares pursuant to the Transaction Documents, are unconditional
and absolute and not subject to any right of set off, counterclaim, delay or reduction, regardless of the effect of any such dilution
or any claim the Company may have against any Purchaser and regardless of the dilutive effect that such issuance may have on the ownership
of the other shareholders of the Company.


 






    34


     


    

 


(b) Notwithstanding
the foregoing clause or anything to the contrary in this Agreement, any Advance Note or any Warrant, each Purchaser hereby agrees that,
in any given calendar month, such Purchaser shall not sell a number of Underlying Shares with respect to any Closing Advance Notes or
any Warrants with a value that exceeds 35% of the aggregate Average Daily Value Traded during such calendar month. For purposes of clarity,
this provision (i) shall only apply as long as there has been no Equity Conditions failure that is continuing and (ii) shall not apply
to the sale of the Underlying Shares with respect to any Prepaid-Tranche by the Initial Collateral Agent.


 


(c) Notwithstanding
anything in this Agreement to the contrary, the Company shall not be deemed in breach of any provision of any Transaction Document for
failure to deliver, and shall have no liability for, and no obligation to deliver, shares of Common Stock (or to pay any damages or other
penalties to the Purchaser for failure to deliver shares of Common Stock) on any request or notice by a Purchaser for conversion of an
Advance Note or, solely as to the Initial Collateral Agent, Prepaid-Tranche, or the exercise of a Warrant, for any shares of Common Stock
the delivery of which would result in (i) such Purchaser exceeding the Beneficial Ownership Limitation set forth in any Advance Note,
Prepaid-Tranche (solely as to the Initial Collateral Agent) or Warrant, as applicable, or (ii) prior to the effectiveness of the Required
Consent, which means 20 days after the first distribution of an Information Statement on Schedule 14(C), the issuance of an aggregate
number of shares of Common Stock hereunder or under any Advance Note, Prepaid-Tranche (solely as to the Initial Collateral Agent) or Warrant
that exceeds the Exchange Cap; provided that the Company shall comply with the waterfall provisions under the definition of Commitment
Amount with respect to shares of Common Stock issued up to the Exchange Cap.


 


4.3 Furnishing of Information;
Public Information.


 


(a) Until the earliest
of the time that (i) no Purchaser owns Securities or (ii) the Warrants have expired, the Company covenants to maintain the registration
of the Common Stock under Section 12(b) or 12(g) of the Exchange Act and to timely file (or obtain extensions in respect thereof and file
within the applicable grace period) all reports required to be filed by the Company after the date hereof pursuant to the Exchange Act
even if the Company is not then subject to the reporting requirements of the Exchange Act.


 


(b) At any time
during the period commencing from the six month anniversary of the date hereof and ending at such time that all of the Underlying Shares
may be sold without the requirement for the Company to be in compliance with Rule 144(c)(1) and otherwise without restriction or limitation
pursuant to Rule 144 (other than any such restriction or limitation arising solely as a result of a Purchaser’s status as an “affiliate”
of the Company, to the extent applicable), if the Company (i) shall fail for any reason to satisfy the current public information requirement
under Rule 144(c) or (ii) has ever been an issuer described in Rule 144 (i)(1)(i) or becomes such an issuer in the future, and the Company
shall fail to satisfy any condition set forth in Rule 144(i)(2) (a “Public Information Failure”) then, in addition
to such Purchaser’s other available remedies, the Company shall pay to a Purchaser, in cash, as partial liquidated damages and not
as a penalty, by reason of any such delay in or reduction of its ability to sell such Underlying Shares, an amount in cash equal to two
percent of the aggregate Subscription Amount of any then outstanding Closing Advance Notes or, solely as to the Initial Collateral Agent,
the Prepaid-Tranches of such Purchaser the resale of the Underlying Shares of which would be affected by the Public Information Failure,
on the day of a Public Information Failure and on every 30th day (pro-rated for periods totaling less than 30 days) thereafter
until the earlier of (A) the date such Public Information Failure is cured and (B) such time that such public information is no longer
required for the Purchasers to transfer such Underlying Shares pursuant to Rule 144. The payments to which a Purchaser shall be entitled
pursuant to this Section 4.3(b) are referred to herein as “Public Information Failure Payments.” Public Information
Failure Payments shall be paid on the earlier of (x) the last day of the calendar month during which such Public Information Failure Payments
are incurred and (y) the third Business Day after the event or failure giving rise to the Public Information Failure Payments is cured.
In the event the Company fails to make Public Information Failure Payments in a timely manner, such Public Information Failure Payments
shall bear interest at the rate of one and one-half percent per month (prorated for partial months) until paid in full. Nothing herein
shall limit such Purchaser’s right to pursue actual damages for the Public Information Failure, and such Purchaser shall have the
right to pursue all remedies available to it at law or in equity including, without limitation, a decree of specific performance and/or
injunctive relief.


 






    35


     


    

 


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


 


4.5 Conversion and Exercise
Procedures. Each of the form of Notice of Exercise included in the Warrants and the form of Notice of Conversion included in the Closing
Advance Notes or, solely as to the Initial Collateral Agent, the Prepaid-Tranches set forth the totality of the procedures required of
the Purchasers in order to exercise the Warrants or convert the Closing Advance Notes or, solely as to the Initial Collateral Agent, the
Prepaid-Tranches. Without limiting the preceding sentences, no ink-original Notice of Exercise or Notice of Conversion shall be required,
nor shall any medallion guarantee (or other type of guarantee or notarization) of any Notice of Exercise or Notice of Conversion form
be required in order to exercise the Warrants or convert the Closing Advance Notes or, solely as to the Initial Collateral Agent, the
Prepaid-Tranches. No additional legal opinion, other information or instructions shall be required of the Purchasers to exercise their
Warrants or convert their Closing Advance Notes or, solely as to the Initial Collateral Agent, the Prepaid-Tranches. The Company shall
honor exercises of the Warrants and conversions of the Closing Advance Notes or, solely as to the Initial Collateral Agent, the Prepaid-Tranches
and shall deliver Underlying Shares, in each case in accordance with the terms and conditions set forth in the Transaction Documents.


 


4.6 Securities Laws Disclosure;
Publicity. The Company shall (a) by the Disclosure Time, issue a press release or file a Current Report on Form 8-K disclosing the
material terms of the transactions contemplated hereby including the fact that there was a Placement Agent, and (b) file a Current Report
on Form 8-K, including the Transaction Documents required under the Exchange Act to be included as exhibits thereto (the “Post-Closing
8-K”), with the Commission within the time required by the Exchange Act (which requirement may be satisfied by the filing of
a Current Report on Form 8-K in accordance with the preceding clause (a)). From and after the issuance of such press release or the filing
of the Post-Closing 8-K in accordance with the preceding clause (a), the Company represents to the Purchasers that it shall have publicly
disclosed all material, non-public information delivered to any of the Purchasers by the Company or any of its Subsidiaries, or any of
their respective officers, directors, employees or agents in connection with the transactions contemplated by the Transaction Documents.
In addition, effective upon the issuance of such press release or the filing of the Post-Closing Form 8-K in accordance with such preceding
clause (a), the Company acknowledges and agrees that any and all confidentiality or similar obligations under any agreement, whether written
or oral, between the Company, any of its Subsidiaries or any of their respective officers, directors, agents, employees or Affiliates
on the one hand, and any of the Purchasers or any of their Affiliates on the other hand, shall terminate with respect to any information
delivered to such Purchasers that could reasonably constitute material, non-public information of the Company or its Subsidiaries. The
Company and each Purchaser shall consult with each other in issuing any other press releases with respect to the transactions contemplated
hereby, and neither the Company nor any Purchaser shall issue any such press release nor otherwise make any such public statement without
the prior consent of the Company, with respect to any press release of any Purchaser, or without the prior consent of each Purchaser,
with respect to any press release of the Company, which consent shall not unreasonably be withheld or delayed, except if such disclosure
is required by law, in which case the disclosing party shall promptly provide the other party with prior notice of such public statement
or communication. Notwithstanding the foregoing, the Company shall not publicly disclose the name of any Purchaser, or include the name
of any Purchaser in any filing with the Commission or any regulatory agency or Trading Market, without the prior written consent of such
Purchaser, except (a) as disclosed in this Agreement, (b) as required by federal securities law in connection with the filing of the Post-Closing
Form 8-K and any applicable final Transaction Documents with the Commission or (c) to the extent such disclosure is required by law or
Trading Market regulations, in which case the Company shall provide the Purchasers with prior notice of such disclosure permitted under
this clause (c), to the extent permitted by applicable law.


 






    36


     


    

 


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


 


4.8 Non-Public Information.
Except with respect to the material terms and conditions of the transactions contemplated by the Transaction Documents and any other information
relating to the Company and its Subsidiaries which shall in each case be disclosed pursuant to Section 4.6, the Company covenants and
agrees that neither it, nor any other Person acting on its behalf will provide any Purchaser or its agents with any information that constitutes,
or the Company reasonably believes constitutes, material non-public information, unless prior thereto such Purchaser shall have consented
to the receipt of such information and agreed with the Company to keep such information confidential. The Company understands and confirms
that each Purchaser shall be relying on the foregoing covenant in effecting transactions in securities of the Company. To the extent that
the Company, any of its Subsidiaries, or any of their respective officers, director, agents, employees or Affiliates delivers any material,
non-public information to a Purchaser without such Purchaser’s consent, the Company hereby covenants and agrees that such Purchaser
shall not have any duty of confidentiality to the Company, any of its Subsidiaries, or any of their respective officers, directors, agents,
employees or Affiliates, or a duty to the Company, any of its Subsidiaries or any of their respective officers, directors, agents, employees
or Affiliates not to trade on the basis of, such material, non-public information, provided that the Purchaser shall remain subject to
applicable law. For the avoidance of doubt, to the extent that any notice provided pursuant to any Transaction Document constitutes, or
contains, or could reasonably be construed to constitute or contain material, non-public information regarding the Company or any of its
Subsidiaries (as determined in good faith by the Company), unless any Purchaser otherwise notifies the Company in writing, such Purchaser
hereby waives its right to receive such notice at any time prior to or substantially concurrently with the public disclosure of such information
by the Company in accordance with applicable securities laws. The Company understands and confirms that each Purchaser shall be relying
on the foregoing covenant in effecting transactions in securities of the Company. The Company shall provide such notification to the Purchasers’
compliance department as designated on Schedule 4.8.


 


4.9 Use of Proceeds.
Except as set forth on Schedule 4.9 attached hereto, the Company shall use the net proceeds from the sale of the Securities hereunder
for working capital and general corporate purposes and shall not use such proceeds: (a) for the satisfaction of any portion of the Company’s
debt (other than payment of trade payables in the ordinary course of the Company’s business and prior practices), (b) for the redemption
of any Common Stock or Common Stock Equivalents, (c) for the settlement of any outstanding litigation or (d) in violation of FCPA or OFAC
regulations.


 






    37


     


    

 


4.10 Indemnification of Purchasers.
Subject to the provisions of this Section 4.10, the Company will indemnify and hold each Purchaser and its directors, officers, shareholders,
members, partners, employees and agents (and any other Persons with a functionally equivalent role of a Person holding such titles notwithstanding
a lack of such title or any other title), each Person who controls such Purchaser (within the meaning of Section 15 of the Securities
Act and Section 20 of the Exchange Act), and the directors, officers, shareholders, agents, members, partners or employees (and any other
Persons with a functionally equivalent role of a Person holding such titles notwithstanding a lack of such title or any other title) of
such controlling Persons (each, a “Purchaser Party”) harmless from any and all losses, liabilities, obligations, claims,
contingencies, damages, costs and expenses, including all judgments, amounts paid in settlements, court costs and reasonable attorneys’
fees and costs of investigation that any such Purchaser Party may suffer or incur as a result of or relating to (a) any breach of any
of the representations, warranties, covenants or agreements made by the Company in this Agreement or in the other Transaction Documents
or (b) any action instituted by the Company or its Affiliates or representatives or agents against the Purchaser Parties in any capacity,
or any of them or their respective Affiliates, with respect to any of the transactions contemplated by the Transaction Documents (unless
such action is based upon a material breach of such Purchaser Party’s representations, warranties or covenants under the Transaction
Documents or any agreements or understandings such Purchaser Party may have with any such stockholder or any violations by such Purchaser
Party of state or federal securities laws or any conduct by such Purchaser Party which is finally judicially determined to constitute
fraud, gross negligence or willful misconduct). If any action shall be brought against any Purchaser Party in respect of which indemnity
may be sought pursuant to this Agreement, such Purchaser Party shall promptly notify the Company in writing, and the Company shall have
the right to assume the defense thereof with counsel of its own choosing reasonably acceptable to the Purchaser Party. Any Purchaser Party
shall have the right to employ separate counsel in any such action and participate in the defense thereof, but the fees and expenses of
such counsel shall be at the expense of such Purchaser Party except to the extent that (i) the employment thereof has been specifically
authorized by the Company in writing, (ii) the Company has failed after a reasonable period of time to assume such defense and to employ
counsel or (iii) in such action there is, in the reasonable opinion of counsel, a material conflict on any material issue between the
position of the Company and the position of such Purchaser Party, in which case the Company shall be responsible for the reasonable fees
and expenses of no more than one such separate counsel. The Company will not be liable to any Purchaser Party under this Agreement (y)
for any settlement by a Purchaser Party effected without the Company’s prior written consent, which shall not be unreasonably withheld
or delayed; or (z) to the extent, but only to the extent that a loss, claim, damage or liability is attributable to any Purchaser Party’s
breach of any of the representations, warranties, covenants or agreements made by such Purchaser Party in this Agreement or in the other
Transaction Documents. The indemnification required by this Section 4.10(a) shall be made by periodic payments of the amount thereof during
the course of the investigation or defense, as and when bills are received or are incurred. The indemnity agreements contained herein
shall be in addition to any cause of action or similar right of any Purchaser Party against the Company or others and any liabilities
the Company may be subject to pursuant to law.


 


4.11 Reservation and Listing
of Securities.


 


(a) The Company
shall maintain a reserve of the Required Minimum from its duly authorized shares of Common Stock for issuance pursuant to the Transaction
Documents in such amount as may then be required to fulfill its obligations in full under the Transaction Documents.


 


(b) If, on any
date, the number of authorized but unissued (and otherwise unreserved, other than for purposes of the Required Minimum) shares of Common
Stock is less than the Required Minimum on such date, then the Board of Directors shall use commercially reasonable efforts to amend the
Company’s certificate or articles of incorporation to increase the number of authorized but unissued shares of Common Stock to at
least the Required Minimum at such time, as soon as possible and in any event not later than the 75th day after such date.


 


(c) The Company
shall, if applicable: (i) in the time and manner required by the Nasdaq Capital Market, prepare and submit a Listing of Additional Shares
Notification the Nasdaq Capital Market covering (A) prior to the Initial Closing, a number of shares of Common Stock equal to at least
300% of the maximum aggregate number of shares of Common Stock potentially issuable in the future pursuant to the Closing Advance Notes
and the Warrants, ignoring any conversion or exercise limits set forth therein, and (B) prior to any Monthly Closing, a number of shares
of Common Stock equal to at least 300% of the maximum aggregate number of shares of Common Stock potentially issuable in the future, solely
to the Initial Collateral Agent, pursuant to the Prepaid-Tranche to be funded by the Initial Collateral Agent at such Monthly Closing,
ignoring any conversion or exercise limits set forth therein, (ii) provide to the Purchasers (or, as to any Monthly Closing, to the Initial
Collateral Agent) a copy of the Listing of Additional Shares Notifications so submitted and (iii) maintain the listing or quotation of
such Common Stock on such Trading Market or another Trading Market.

4.12 Participation in Future
Financing.


 


(a) From the date
hereof until the 18 month anniversary of the date of this Agreement, upon any issuance by the Company or any of its Subsidiaries of Common
Stock or Common Stock Equivalents, or a combination of units consisting of Common Stock and Common Stock Equivalents for cash consideration
(a “Subsequent Financing”), the Purchasers shall have the right to participate, in the aggregate, for up to an amount
of the Subsequent Financing equal to 20% of the Subsequent Financing (the “Participation Maximum”) on the same terms,
conditions and price provided for in the Subsequent Financing; provided that, with respect to any Permitted Private Placement Financing,
the Purchasers shall have the right to participate for up to an amount equal to the Participation Maximum, which amount shall be in excess
of and added to the aggregate amount of the Subsequent Financing (for the avoidance of doubt, without reducing the amount of the Subsequent
Financing to be acquired by the purchaser in such Subsequent Financing).


 


(b) Between the
time period of 4:00 pm (New York City time) and 6:00 pm (New York City time) on the Trading Day immediately prior to the Trading Day of
the expected announcement of the Subsequent Financing (or, if the Trading Day of the expected announcement of the Subsequent Financing
is the first Trading Day following a holiday or a weekend (including a holiday weekend), between the time period of 4:00 pm (New York
City time) on the Trading Day immediately prior to such holiday or weekend and 2:00 pm (New York City time) on the day immediately prior
to the Trading Day of the expected announcement of the Subsequent Financing), the Company shall deliver to each Purchaser a written notice
of the Company’s intention to effect a Subsequent Financing (a “Subsequent Financing Notice”), which notice shall
describe in reasonable detail the proposed terms of such Subsequent Financing, the amount of proceeds intended to be raised thereunder
and the Person or Persons through or with whom such Subsequent Financing is proposed to be effected and shall include a term sheet, to
the extent applicable, and transaction documents relating thereto as an attachment.


 


(c) Any Purchaser
desiring to participate in such Subsequent Financing must provide written notice to the Company by 6:30 am (New York City time) on the
Trading Day following the date on which the Subsequent Financing Notice is delivered to such Purchaser (the “Notice Termination
Time”) that such Purchaser is willing to participate in the Subsequent Financing, the amount of such Purchaser’s participation
(up to the Participation Maximum), and representing and warranting that such Purchaser has such funds ready, willing, and available for
investment on the terms set forth in the Subsequent Financing Notice. If the Company receives no such notice from a Purchaser as of such
Notice Termination Time, such Purchaser shall be deemed to have notified the Company that it does not elect to participate in such Subsequent
Financing.


 


(d) If, by the
Notice Termination Time, notifications by the Purchasers of their willingness to participate in the Subsequent Financing (or to cause
their designees to participate) is, in the aggregate, less than the Participation Maximum, then the Company may effect the remaining portion
of such Subsequent Financing (including the portion of the Participation Maximum not so subscribed by the Purchasers) on the terms and
with the Persons set forth in the Subsequent Financing Notice.


 


(e) If, by the
Notice Termination Time, the Company receives responses to a Subsequent Financing Notice from Purchasers seeking to purchase more than
the aggregate amount of the Participation Maximum, each such Purchaser shall have the right to purchase its Pro Rata Portion (as defined
below) of the Participation Maximum. “Pro Rata Portion” means the ratio of (x) the Principal of the Advance Closing
Notes purchased on the Closing Date by a Purchaser participating under this Section 4.12 and (y) the sum of the aggregate Principal of
all Advance Closing Notes purchased on the Closing Date by all Purchasers participating under this Section 4.12.


 


(f) The Company
must provide the Purchasers with a second Subsequent Financing Notice, and the Purchasers will again have the right of participation set
forth above in this Section 4.11, if the definitive agreement related to the initial Subsequent Financing Notice is not entered into for
any reason on the terms set forth in such Subsequent Financing Notice within two (2) Trading Days after the date of delivery of the initial
Subsequent Financing Notice.


 






    39


     


    

 


(g)
The Company and each Purchaser agree that, if any Purchaser elects to participate in the Subsequent Financing, the transaction
documents related to the Subsequent Financing shall not include any term or provision that, directly or indirectly, will, or is intended
to, exclude one or more of the Purchasers from participating in a Subsequent Financing, including, but not limited to, provisions whereby
such Purchaser shall be required to agree to any restrictions on trading as to any securities of the Company or be required to consent
to any amendment to or termination of, or grant any waiver, release or the like under or in connection with, this Agreement, without
the prior written consent of such Purchaser. In addition, the Company and each Purchaser agree that, in connection with a Subsequent
Financing, the transaction documents related to the Subsequent Financing shall include a requirement for the Company to issue a widely
disseminated press release by 9:30 am (New York City time) on the Trading Day of execution of the transaction documents in such Subsequent
Financing (or, if the date of execution is not a Trading Day, on the immediately following Trading Day) that discloses the material terms
of the transactions contemplated by the transaction documents in such Subsequent Financing.


 


(h) Notwithstanding
anything to the contrary in this Section 4.12 and unless otherwise agreed to by such Purchaser, the Company shall either confirm in writing
to such Purchaser that the transaction with respect to the Subsequent Financing has been abandoned or shall publicly disclose its intention
to issue the securities in the Subsequent Financing, in either case in such a manner such that such Purchaser will not be in possession
of any material, non-public information, by 9:30 am (New York City time) on the second (2nd) Trading Day following date of delivery of
the Subsequent Financing Notice. If by 9:30 am (New York City time) on such second (2nd) Trading Day, no public disclosure regarding a
transaction with respect to the Subsequent Financing has been made, and no notice regarding the abandonment of such transaction has been
received by such Purchaser, such transaction shall be deemed to have been abandoned and such Purchaser shall not be deemed to be in possession
of any material, non-public information with respect to the Company or any of its Subsidiaries.


 


(i) Notwithstanding
the foregoing, this Section 4.12 shall not apply in respect of any Exempt Issuance.


 


4.13 Subsequent Equity Sales.


 


(a) From the date
hereof until the date that is 120 days after the date hereof (the “Restricted Period”), neither the Company nor any
Subsidiary shall (i) issue, enter into any agreement to issue or announce the issuance or proposed issuance of any shares of Common Stock
or Common Stock Equivalents, other than up to $5,000,000 of “restricted securities” issued without registration rights that
would require or permit the registration of such “restricted securities” for resale at any time during the Restricted Period
or provide for any participation rights (the “Permitted Private Placement Financing”), or (ii) file any registration
statement or any amendment or supplement thereto, in each case other than as contemplated pursuant to the Registration Rights Agreement.


 






    40


     


    

 


(b)
From the date hereof until the 18-month anniversary of the date of this Agreement, the Company shall not effect or enter into an agreement
to effect any issuance by the Company or any of its Subsidiaries of Common Stock or Common Stock Equivalents (or a combination of units
thereof) involving a Variable Rate Transaction. “Variable Rate Transaction” means a transaction in which the Company
issues or sells any debt or equity securities that are convertible into, exchangeable or exercisable for, or include the right to receive,
additional shares of Common Stock either (i) at a conversion price, exercise price or exchange rate or other price that is based upon,
and/or varies with, the trading prices of or quotations for the shares of Common Stock at any time after the initial issuance of such
debt or equity securities or (ii) with a conversion, exercise or exchange price that is subject to being reset at some future date after
the initial issuance of such debt or equity security or upon the occurrence of specified or contingent events directly or indirectly
related to the business of the Company or the market for the Common Stock (in each case, other than in connection with stock splits,
combinations, recapitalizations or reclassifications). For the purposes of this Section 4.13(b), any Equity Line and an At the Market
Offering shall each be a Variable Rate Transaction. “Equity Line” shall include any transaction involving a written agreement
between the Company and counterparty whereby the Company has the right to “put” its securities to the counterparty over an
agreed period of time and at an agreed price or price formula based on the trading prices of or quotations for the shares of Common Stock
at such time. Provided, however, the Company may effect sales pursuant to an At the Market Offering to a registered broker-dealer
more than 10 Trading Days after any conversion by the holder of an Advance or Prepaid-Tranche or any Monthly Closing. Any Purchaser shall
be entitled to obtain injunctive relief against the Company to preclude any such issuance, which remedy shall be in addition to any right
to collect damages.


 


(c)
Notwithstanding the foregoing, this Section 4.13 shall not apply in respect of any Exempt Issuance.


 


4.14
Equal Treatment of Purchasers. No consideration (including any modification of any Transaction Document) shall be offered or paid
to any Person to amend or consent to a waiver or modification of any provision of the Transaction Documents unless the same consideration
is also offered to all of the parties to such Transaction Documents. Further, the Company shall not make any payment of principal or
interest on the Advance Notes in amounts which are disproportionate to the respective principal amounts outstanding on the Advance Notes
at any applicable time. For clarification purposes, this provision constitutes a separate right granted to each Purchaser by the Company
and negotiated separately by each Purchaser and is intended for the Company to treat the Purchasers as a class and shall not in any way
be construed as the Purchasers acting in concert or as a group with respect to the purchase, disposition or voting of Securities or otherwise.


 






    41


     


    

 


4.15
Certain Transactions and Confidentiality. Each Purchaser, severally and not jointly with the other Purchasers, covenants that
until such time as the transactions contemplated by this Agreement are publicly disclosed by the Company pursuant to the initial press
release as described in Section 4.6, such Purchaser will maintain the confidentiality of the existence and terms of this transaction
and the information included in the Disclosure Schedules. Notwithstanding the foregoing, and notwithstanding anything contained in this
Agreement to the contrary, the Company expressly acknowledges and agrees that (i) no Purchaser makes any representation, warranty or
covenant hereby that it will not engage in effecting transactions in any securities of the Company after the time that the transactions
contemplated by this Agreement are first publicly announced pursuant to the initial press release or Post-Closing 8-K as described in
Section 4.6(a) and (ii) no Purchaser shall be restricted or prohibited from effecting any transactions in any securities of the Company
in accordance with applicable securities laws from and after the time that the transactions contemplated by this Agreement are first
publicly announced pursuant to the initial press release or Post-Closing 8-K as described in Section 4.6(a). Notwithstanding the foregoing,
in the case of a Purchaser that is a multi-managed investment vehicle whereby separate portfolio managers manage separate portions of
such Purchaser’s assets and the portfolio managers have no direct knowledge of the investment decisions made by the portfolio managers
managing other portions of such Purchaser’s assets, the covenant set forth above shall only apply with respect to the portion of
assets managed by the portfolio manager that made the investment decision to purchase the Securities covered by this Agreement.


 


4.16
Form D; Blue Sky Filings. The Company agrees to timely file a Form D with respect to the $2.5M Closing Advance Notes as required
under Regulation D and to provide a copy thereof, promptly upon request of any Purchaser. The Company shall take such action as the Company
shall reasonably determine is necessary in order to obtain an exemption for, or to qualify the Securities for, sale to the Purchasers
at each Closing under applicable securities or “Blue Sky” laws of the states of the United States and shall provide evidence
of such actions promptly upon request of any Purchaser.


 


4.17
Capital Changes. From the date hereof until the 18-month anniversary of this Agreement, the Company shall not undertake a reverse
or forward stock split or reclassification of the Common Stock without the prior written consent of the Required Holders.


 


4.18
[Reserved]


 


4.19
Minimum Cash Covenant. The Company agrees with each Purchaser and the Collateral Agent that, beginning with the issuance by the
Company of the initial monthly Advance Note pursuant to Section 2.1(b) above (for the avoidance of doubt, not including the Closing Advance
Notes) and until no Closing Advance Notes or, solely as to the Initial Collateral Agent, Prepaid-Tranches are outstanding, the Company
will not, unless the Required Holders shall otherwise consent, permit its and its Subsidiaries’ aggregate minimum cash balance
in its bank accounts (which includes money market accounts at such banks) to be less than $3,000,000 (the “Threshold”).
During such period:


 


(a)
If the cash balance is below the Threshold as of the end of any Business Day (determined as of 5pm Eastern Time), the Company shall have
a one-time 15 day cure period and, if not cured by such date, the Company shall be in breach of this Section 4.19.


 


(b)
Within two Business Days after the end of each week, the Company shall deliver to the Collateral Agent a certificate of a financial officer
of the Company (the “Compliance Certificate”) demonstrating in reasonable detail satisfactory to the Required Holders
the Company’s compliance with the covenant set forth in this Section 4.19 (the “Minimum Cash Covenant”).


 


(c)
Upon receipt by the Collateral Agent of any Compliance Certificate demonstrating the Company’s failure to comply with the Minimum
Cash Covenant, the Collateral Agent shall not provide notice of such default to the Purchasers unless and until the Company shall remain
in default with respect thereto upon the expiration of any Cure Period (if any) with respect thereto.


 






    42


     


    

 


4.20
Collateral Agent.


 


(a)
Each Purchaser hereby (i) appoints the Initial Collateral Agent as the collateral agent hereunder and under the Security Agreement (in
such capacity, the “Collateral Agent”), and (ii) authorizes the Collateral Agent (and its officers, directors, employees
and agents) to take such action on such Purchaser’s behalf in accordance with the terms in this Agreement and the Security Agreement.
The Collateral Agent shall not have, by reason hereof or pursuant to any Security Agreement, a fiduciary relationship in respect of any
other Purchaser. Neither the Collateral Agent nor any of its officers, directors, employees and agents shall have any liability to any
other Purchaser for any action taken or omitted to be taken in connection hereof or the Security Agreement except to the extent caused
by its own gross negligence or willful misconduct, and each other Purchaser agrees to defend, protect, indemnify and hold harmless the
Collateral Agent and all of its officers, directors, employees and agents (collectively, the “Collateral Agent Indemnitees”)
from and against any losses, damages, liabilities, obligations, penalties, actions, judgments, suits, fees, costs and expenses (including,
without limitation, reasonable attorneys’ fees, costs and expenses) incurred by such Collateral Agent Indemnitee, whether direct,
indirect or consequential, arising from or in connection with the performance by such Collateral Agent Indemnitee of the duties and obligations
of Collateral Agent pursuant hereto or the Security Agreement.


 


(b)
The Collateral Agent shall be entitled to rely upon any written notices, statements, certificates, orders or other documents or any telephone
message believed by it in good faith to be genuine and correct and to have been signed, sent or made by the proper Person, and with respect
to all matters pertaining to this Agreement or any of the other Transaction Documents and its duties hereunder or thereunder, upon advice
of counsel selected by it.


 


(c)
The Collateral Agent may resign from the performance of all its functions and duties hereunder and under the Closing Advance Notes and,
solely as to the Initial Collateral Agent, the Prepaid-Tranches, and the Security Agreement, at any time by giving at least 10 Business
Days prior written notice to the Company and each holder of the Closing Advance Notes or, solely as to the Initial Collateral Agent,
any Prepaid-Tranches. Such resignation shall take effect upon the acceptance by a successor Collateral Agent of appointment as provided
below. Upon any such notice of resignation, the Required Holders shall appoint a successor Collateral Agent. Upon the acceptance of the
appointment as Collateral Agent, such successor Collateral Agent shall succeed to and become vested with all the rights, powers, privileges
and duties of the retiring Collateral Agent, and the retiring Collateral Agent shall be discharged from its duties and obligations under
this Agreement, the Advance Notes and the Security Agreement. After any Collateral Agent’s resignation hereunder, the provisions
of this Section 4.20 shall inure to its benefit. If a successor Collateral Agent shall not have been so appointed within said 10 Business
Day period, the retiring Collateral Agent shall then appoint a successor Collateral Agent who shall serve until such time, if any, as
the Required Holders appoints a successor Collateral Agent as provided above.


 


(d)
The Company hereby covenants and agrees to take all actions as promptly as practicable reasonably requested by either the Required Holders
or the Collateral Agent (or its successor), from time to time pursuant to the terms of this Section 4.20, to secure a successor Collateral
Agent satisfactory to such requesting part(y)(ies), in their sole discretion, including, without limitation, by paying all reasonable
and customary fees of such successor Collateral Agent, by having the Company agree to indemnify any successor Collateral Agent (except
to the extent of any action caused by its own gross negligence or willful misconduct) in a customary manner and by executing a collateral
agency agreement or similar agreement and/or any amendment to the Security Agreement reasonably requested or required by the successor
Collateral Agent on terms substantially consistent with the terms of the Security Agreement.


 






    43


     


    

 


4.21
No Amendment of Existing Registration Rights. The Company shall not amend the registration rights presently in existence in any
manner which adversely affects the rights of the Purchasers.


 


4.22
Shareholder Consent/Information Statement. At or prior to the Initial Closing, the Company will deliver to the Purchasers the
executed Required Consent. Within 10 days following the Closing, the Company shall prepare and file with the Commission an Information
Statement on Schedule 14C in preliminary form. The Company shall promptly provide responses to the SEC with respect to any comments received
on such Information Statement from the SEC, and the Company shall cause the definitive Information Statement to be distributed and made
available to shareholders promptly after the date the SEC staff advises that it has no further comments thereof or that the Company may
commence distributing the Information Statement.


 


4.23
No Interference with Form S-3. The Company covenants that it shall take no action under or with respect to the Form S-3, including
the sale of Securities to other Persons issued pursuant to such Form S-3, which interferes with or adversely affects the rights of the
Purchasers to convert (a) $12.5 million of the $12.5M Closing Advance Notes into shares of Common Stock in accordance with the terms thereof
or (b) the Principal Amount of any Registered Advance Note issued pursuant to the Form S-3 after the date hereof and, in each case, to
sell such Underlying Shares as provided under Section 3.1(qq) and, except to the extent the Commission has issued any stop order or other
order suspending the effectiveness of the Form S-3 or the Company has failed to timely file (or obtain extensions in respect thereof
and file within the applicable grace period) all reports required to be filed by the Company pursuant to the Exchange Act, shall at all
times take the position that the Form S-3 is available for the sale of the Underlying Shares issuable pursuant to the conversion of the
Registered Advance Notes (including the $12.5M Closing Advance Notes).


 


4.24
Prospectus Supplement. On the date hereof, the Company shall file a prospectus supplement to its Form S-3 (the “Prospectus
Supplement”) with the Commission covering the issuance and sale of the $12.5M Closing Advance Notes and the Underlying Shares
thereof, pursuant to which the Purchasers shall receive freely tradeable shares of Common Stock on any conversion, at the discretion
of each Purchaser, of its ratable portion of the $12.5M Closing Advance Notes. On each Monthly Closing Date, the Company shall file a
Prospectus Supplement with the Commission covering the issuance and sale to the Initial Collateral Agent of the Prepaid-Tranche to be
issued to the Initial Collateral Agent at such Monthly Closing and the Underlying Shares thereof, pursuant to which the Initial Collateral
Agent shall receive freely tradeable shares of Common Stock on any conversion, at the discretion of the Initial Collateral Agent, of
its Prepaid-Tranche.


 






    44


     


    

 


4.25
Optional Repayment and Termination.


 


(a)
At any time after the Prepaid-Tranche Commencement, the Company may deliver written notice (a “Repayment/Termination Notice”)
to the Purchasers, indicating that it desires to repay all outstanding Closing Advance Notes and, solely as to the Initial Collateral
Agent, Prepaid-Tranches and to terminate the Company’s and the Purchasers’ obligations under this Agreement, the Closing
Advance Notes, any Prepaid-Tranches and the other Transaction Documents.


 


(b)
Following the Purchasers’ receipt of a Repayment/Termination Notice, if the Initial Collateral Agent is then entitled to, but has
not yet exercised, one or both of its Purchaser Advance Note Options, the Initial Collateral Agent shall have the right to (i) exercise
one Purchaser Advance Note Option in the 60 Trading Days following receipt of the Repayment/Termination Notice and (ii) exercise both
of its Purchaser Advance Note Options in the 90 Trading Days following receipt of the Repayment/Termination Notice, in each case on the
terms and subject to the conditions set forth in this Agreement. The Initial Collateral Agent’s right to exercise any Purchaser
Advance Note Option shall terminate as of the earlier of (A) the end of the 60 Trading Day period specified in clause (i) above, if the
Initial Collateral Agent has not exercised any Purchaser Advance Note Option in such 60 Trading Day period or has exercised such Purchaser
Advance Note Option and has no Purchaser Advance Note Options remaining and (B) otherwise, the end of the 90 Trading Day period specified
in clause (ii) above (the “Advance Note Option Expiration Date”).


 


(c)
Following the Advance Note Option Expiration Date, at such time as the aggregate outstanding principal amount of any Closing Advance
Notes or, solely as to the Initial Collateral Agent, Prepaid-Tranches is less than $300,000, the Company shall have the right, on 20
Trading Days’ prior written notice (a “Call Notice”) to the holder or holders of such Closing Advance Notes
or, solely as to the Initial Collateral Agent, Prepaid-Tranches, to repay the aggregate outstanding principal amount of such Closing
Advance Notes or, solely as to the Initial Collateral Agent, Prepaid-Tranches, in cash, at a repayment price equal to 120% of the outstanding
principal amount thereof; provided that, prior to the end of such 20 Trading Day period, the holder of any such Advance Note or,
solely as to the Initial Collateral Agent, Prepaid-Tranche, shall have the right to convert the remaining outstanding Principal thereof
into shares of Common Stock in accordance with the terms of the applicable Advance Note or, solely as to the Initial Collateral Agent,
Prepaid-Tranche.


 


(d)
At such time as no Closing Advance Notes or Prepaid-Tranches remain outstanding under this Agreement, the Company shall have the right
to terminate this Agreement and the other Transaction Documents in full, at which time none of the Company or any of its Affiliates nor
any Purchaser or any of its Affiliates shall have any further rights or obligations under any of the Transaction Documents; provided,
however, that (i) the provisions of Section 4.10 hereof shall survive any such termination and (ii) no such termination will affect
the right of any party to sue for any breach by any other party (or parties).


 


4.26
Pledges. Within 30 days after (a) the Company has organized a Subsidiary, other than an Excluded Subsidiary, or (b) such time
after a Subsidiary ceases to be deemed an Excluded Subsidiary, the Company shall execute and deliver to the Purchasers, as applicable,
the Pledge Agreement and deliver the Pledged Securities to the Collateral Agent.

MISCELLANEOUS


 


5.1
Termination. This Agreement may be terminated by any Purchaser, as to such Purchaser’s obligations hereunder only and without
any effect whatsoever on the obligations between the Company and the other Purchasers, by written notice to the other parties, if the
Initial Closing has not been consummated on or before the fifth Trading Day following the date hereof, provided, however,
that no such termination will affect the right of any party to sue for any breach by any other party (or parties). Unless earlier terminated
in accordance with the terms hereof, this Agreement shall terminate on such date after June 19, 2024 that no Closing Advance Notes, Prepaid-Tranches
or Warrants remain outstanding under this Agreement; provided, however, that (i) the provisions of Section 4.10 hereof
shall survive any such termination and (ii) no such termination will affect the right of any party to sue for any breach by any other
party (or parties).


 


5.2
Fees and Expenses. At the Initial Closing, the Company has agreed to reimburse the Collateral Agent up to $65,000 for its legal
fees and expenses, $20,000 of which has been paid prior to the Closing. The Company shall deliver to each Purchaser, prior to the Closing,
a completed and executed copy of the Closing Statement, attached hereto as Annex A. Except as expressly set forth in the Transaction
Documents to the contrary, each party shall pay the fees and expenses of its advisers, counsel, accountants and other experts, if any,
and all other expenses incurred by such party incident to the negotiation, preparation, execution, delivery and performance of this Agreement.
The Company shall pay all Transfer Agent fees (including, without limitation, any fees required for same-day processing of any instruction
letter delivered by the Company and any conversion or exercise notice delivered by a Purchaser), stamp taxes and other taxes and duties
levied in connection with the delivery of any Securities to each Purchaser and costs necessary to provide the Purchasers with a Lien
on all of the assets of the Company.


 


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


 






    46


     


    

 


5.4

writing and shall be deemed given and effective on the earliest of: (a) the time of transmission, if such notice or communication is
delivered via email at the email address as set forth on the signature pages attached hereto at or prior to 5:30 p.m. (New York, N.Y.
time) on a Trading Day, (b) the next Trading Day after the time of transmission, if such notice or communication is delivered via email

5.5
Amendments; Waivers. No provision of this Agreement may be waived, modified, supplemented or amended except in a written instrument
signed, in the case of an amendment, by the Company and the Required Holders or, in the case of a waiver, by the party against whom enforcement
of any such waived provision is sought, provided that if any amendment, modification or waiver disproportionately and adversely impacts
a Purchaser (or Purchasers), the consent of such disproportionately impacted Purchaser (or Purchasers) shall also be required. No waiver
of any default with respect to any provision, condition or requirement of this Agreement shall be deemed to be a continuing waiver in
the future or a waiver of any subsequent default or a waiver of any other provision, condition or requirement hereof, nor shall any delay
or omission of any party to exercise any right hereunder in any manner impair the exercise of any such right. Any proposed amendment
or waiver that disproportionately, materially and adversely affects the rights and obligations of any Purchaser relative to the comparable
rights and obligations of the other Purchasers shall require the prior written consent of such adversely affected Purchaser. Any amendment
effected in accordance with this Section 5.5 shall be binding upon each Purchaser and holder of Securities and the Company. Such amendment
provision shall not be construed to mean that the Beneficial Ownership Limitation (as defined in the Advance Note or, solely as to the
Initial Collateral Agent, Prepaid-Tranche) of the Advance Note or, solely as to the Initial Collateral Agent, Prepaid-Tranche may be
amended.


 


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


 


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


 


5.8
No Third-Party Beneficiaries. The Placement Agent shall be the third-party beneficiary of the representations and warranties of
the Company in Section 3.1(oo) and the representations and warranties of the Purchasers in Section 3.2. This Agreement is intended for
the benefit of the parties hereto and their respective successors and permitted assigns and is not for the benefit of, nor may any provision
hereof be enforced by, any other Person, except as otherwise set forth in Section 4.10 and this Section 5.8.

5.9
Governing Law; Exclusive Jurisdiction.


 


(a)
All questions concerning the construction, validity, enforcement and interpretation of the Transaction Documents (other than the Prepaid-Tranches)
shall be governed by and construed and enforced in accordance with the internal laws of the State of New York, without regard to the
principles of conflicts of law thereof. Each party agrees that all Actions or Proceedings concerning the interpretations, enforcement
and defense of the transactions contemplated by this Agreement and any other Transaction Documents (other than the Prepaid-Tranches)
(whether brought against a party hereto or its respective Affiliates, directors, officers, shareholders, partners, members, employees
or agents) shall be commenced exclusively in the state and federal courts sitting in the City of New York. Each party hereby irrevocably
submits to the exclusive jurisdiction of the state and federal courts sitting in the City of New York, Borough of Manhattan, for the
adjudication of any dispute hereunder or in connection herewith or with any transaction contemplated hereby or discussed herein (including
with respect to the enforcement of any of the Transaction Documents (other than the Prepaid-Tranches)), and hereby irrevocably waives,
and agrees not to assert in any Action or Proceeding, any claim that it is not personally subject to the jurisdiction of any such court,
that such Action or Proceeding is improper or is an inconvenient venue for such Proceeding.


 


(b)
All questions concerning the construction, validity, enforcement and interpretation of the Prepaid-Tranches shall be governed by and
construed and enforced in accordance with the internal laws of the Cayman Islands, without regard to the principles of conflicts of law
thereof. Each party agrees that all Actions or Proceedings concerning the interpretations, enforcement and defense of the transactions
contemplated by the Prepaid-Tranches (whether brought against a party hereto or its respective Affiliates, directors, officers, shareholders,
partners, members, employees or agents) shall be commenced exclusively in the state and federal courts located in Miami-Dade County,
Florida. Each party hereby irrevocably submits to the exclusive jurisdiction of any Miami-Dade County, Florida State court or Federal
court of the United States of America sitting in the Southern District of Florida, and any appellate court from any thereof, for the
adjudication of any dispute hereunder or in connection herewith or with any transaction contemplated hereby or discussed herein (including
with respect to the enforcement of any of the Prepaid-Tranches), and hereby irrevocably waives, and agrees not to assert in any Action
or Proceeding, any claim that it is not personally subject to the jurisdiction of any such court, that such Action or Proceeding is improper
or is an inconvenient venue for such Proceeding. For the avoidance of doubt, the internal laws of the Cayman Islands shall be applied
to the determination of whether any usury laws are applicable to the terms and conditions of, or any amounts due under, the Prepaid-Tranches.
Such reference to usury laws shall not be construed to mean that there are applicable usury laws under the laws of the Cayman Islands.


 


(c)
Each party hereby irrevocably waives personal service of process and consents to process being served in any such Action or Proceeding
by mailing a copy thereof via registered or certified mail or overnight delivery (with evidence of delivery) to such party at the address
in effect for notices to it under this Agreement and agrees that such service shall constitute good and sufficient service of process
and notice thereof. Nothing contained herein shall be deemed to limit in any way any right to serve process in any other manner permitted
by law. If any party shall commence an Action or Proceeding to enforce any provisions of the Transaction Documents, then, in addition
to the obligations of the Company under Section 4.10, the prevailing party in such Action or Proceeding shall be reimbursed by the non-prevailing
party for its reasonable attorneys’ fees and other costs and expenses incurred with the investigation, preparation and prosecution
of such Action or Proceeding.


 






    48


     


    

 


5.10
Survival. The representations and warranties contained herein shall survive each Closing and the delivery of the Securities for
a period of 36 months after the last Monthly Closing. For avoidance of doubt, the Initial Collateral Agent shall have no obligation to
fund any Monthly Closings after June 19, 2024.


 


5.11
Execution. This Agreement may be executed in two or more counterparts, all of which when taken together shall be considered one
and the same agreement and shall become effective when counterparts have been signed by each party and delivered to each other party,
it being understood that the parties need not sign the same counterpart. In the event that any signature is delivered by facsimile transmission
or by e-mail delivery of a “.pdf” format data file, such signature shall create a valid and binding obligation of the party
executing (or on whose behalf such signature is executed) with the same force and effect as if such facsimile or “.pdf” signature
page were an original thereof. Each of the parties hereto agrees and acknowledges that (a) the transaction consisting of this Agreement
and the other Transaction Document may be conducted by electronic means, (b) it is such party’s intent that, if such party signs
this Agreement or any other Transaction Document using an electronic signature, it is signing, adopting and accepting this Agreement
or such other Transaction Document and that signing this Agreement or such other Transaction Document using an electronic signature is
the legal equivalent of having placed its handwritten signature on this Agreement or such Transaction Document on paper and (c) it is
being provided with an electronic or paper copy of this Agreement in a usable format.


 


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


 


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


 






    49


     


    

 


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


 


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


 


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


 


5.17
Usury. To the extent it may lawfully do so, the Company hereby agrees not to insist upon or plead or in any manner whatsoever
claim, and will resist any and all efforts to be compelled to take the benefit or advantage of, usury laws wherever enacted, now or at
any time hereafter in force, in connection with any Proceeding that may be brought by any Purchaser in order to enforce any right or
remedy under any Transaction Document or any Proceeding instituted by the Company relating to any Transaction Document. Notwithstanding
any provision to the contrary contained in any Transaction Document, it is expressly agreed and provided that the total liability of
the Company under the Transaction Documents for payments in the nature of interest shall not exceed the maximum lawful rate authorized
under applicable law (the “Maximum Rate”), if any, and, without limiting the foregoing, in no event shall any rate
of interest or default interest, or both of them, when aggregated with any other sums in the nature of interest that the Company may
be obligated to pay under the Transaction Documents exceed such Maximum Rate. It is agreed that if the maximum contract rate of interest
allowed by law and applicable to the Transaction Documents is increased or decreased by statute or any official governmental action subsequent
to the date hereof, the new maximum contract rate of interest allowed by law will be the Maximum Rate applicable to the Transaction Documents
from the effective date thereof forward, unless such application is precluded by applicable law. If under any circumstances whatsoever,
interest in excess of the Maximum Rate is paid by the Company to any Purchaser with respect to Indebtedness evidenced by the Transaction
Documents, such excess shall be applied by such Purchaser to the unpaid principal balance of any such Indebtedness or be refunded to
the Company, the manner of handling such excess to be at such Purchaser’s election.


 






    50


     


    

 


5.18
Independent Nature of Purchasers’ Obligations and Rights. The obligations of each Purchaser under any Transaction Document
are several and not joint with the obligations of any other Purchaser, and no Purchaser shall be responsible in any way for the performance
or non-performance of the obligations of any other Purchaser under any Transaction Document, including, but not limited to, with respect
to the Initial Collateral Agent’s obligations in respect of the purchase of Prepaid-Tranches from the Company. Nothing contained
herein or in any other Transaction Document, and no action taken by any Purchaser pursuant hereto or thereto, shall be deemed to constitute
the Purchasers as a partnership, an association, a joint venture or any other kind of entity, or create a presumption that the Purchasers
are in any way acting in concert or as a group with respect to such obligations or the transactions contemplated by the Transaction Documents.
Each Purchaser shall be entitled to independently protect and enforce its rights, including, without limitation, the rights arising out
of this Agreement or out of the other Transaction Documents, and it shall not be necessary for any other Purchaser to be joined as an
additional party in any Proceeding for such purpose. Each Purchaser has been represented by its own separate legal counsel in its review
and negotiation of the Transaction Documents. For reasons of administrative convenience only, each Purchaser and its respective counsel
have chosen to communicate with the Company through Nason Yeager. Nason Yeager does not represent any of the Purchasers (other than the
Initial Collateral Agent). The Company has elected to provide all Purchasers with the same terms and Transaction Documents for the convenience
of the Company and not because it was required or requested to do so by any of the Purchasers. It is expressly understood and agreed
that each provision contained in this Agreement and in each other Transaction Document is between the Company and a Purchaser, solely,
and not between the Company and the Purchasers collectively and not between and among the Purchasers.


 


5.19
Liquidated Damages. The Company’s obligations to pay any partial liquidated damages or other amounts owing under the Transaction
Documents is a continuing obligation of the Company and shall not terminate until all unpaid partial liquidated damages and other amounts
have been paid notwithstanding the fact that the instrument or security pursuant to which such partial liquidated damages or other amounts
are due and payable shall have been canceled.


 


5.20
Saturdays, Sundays, Holidays, etc. If the last or appointed day for the taking of any Proceeding or the expiration of any right
required or granted herein shall not be a Business Day, then such action may be taken, or such right may be exercised on the next succeeding
Business Day.


 


5.21
Construction. The parties agree that each of them and/or their respective counsel have reviewed and had an opportunity to revise
the Transaction Documents and, therefore, the normal rule of construction to the effect that any ambiguities are to be resolved against
the drafting party shall not be employed in the interpretation of the Transaction Documents or any amendments thereto. In addition, each
and every reference to share prices and shares of Common Stock in any Transaction Document shall be subject to adjustment for reverse
and forward stock splits, stock dividends, stock combinations and other similar transactions of the Common Stock that occur after the
date of this Agreement.


 


5.22
WAIVER OF JURY TRIAL. IN ANY ACTION, SUIT, OR PROCEEDING IN ANY JURISDICTION BROUGHT BY ANY PARTY AGAINST ANY OTHER PARTY,
THE PARTIES EACH KNOWINGLY AND INTENTIONALLY, TO THE GREATEST EXTENT PERMITTED BY APPLICABLE LAW, HEREBY ABSOLUTELY, UNCONDITIONALLY,
IRREVOCABLY AND EXPRESSLY WAIVES FOREVER TRIAL BY JURY.

FOR VALUE RECEIVED,
ASCENT SOLAR TECHNOLOGIEs, INC., a Delaware corporation (the “Company”),
hereby promises to pay to the order of [_____________________________], or its registered assigns (the “Holder”) the
principal sum of $[_________] (the “Principal”) pursuant to the terms of this Senior Secured Original Issue 10% Discount
Convertible Advance Note (the “Advance Note”). In exchange for delivery of this Advance Note on the Original Issuance
Date referred to above, the Holder shall advance to the Company $[                   ]
in United States dollars net of an original issuance discount of $[                    ].
This Advance Note is issued pursuant to a Securities Purchase Contract entered into as of the Original Issuance Date by and among the
Company, the Holder and the holder of another Advance Note (the “Purchase Agreement”). All capitalized words and terms
not defined in this Advance Note have the meanings contained in the Purchase Agreement.


 


Unless earlier converted pursuant
to the terms of Article 3, the Maturity Date of this Advance Note shall be 18 months from the Original Issuance Date of this Advance Note
which is specified above, unless the Holder has given notice to the Company that it elects to accelerate the Maturity Date to the extent
explicitly permitted by this Advance Note (the “Maturity Date”). The Maturity Date is the date upon which the Principal

ARTICLE
1


 


1.1 Purchase
Agreement; Subsidiary Guarantee. This Advance Note has been executed and delivered pursuant to, and is one of the Closing
Advance Notes, as defined in and issued pursuant to, the Purchase Agreement. The full amount of this Advance Note and all the cash
payment obligations of the Company under the Transaction Documents shall be guaranteed in full by each Subsidiary, other than any
Excluded Subsidiary, pursuant to a Subsidiary Guarantee in the form attached as an exhibit to the Purchase Agreement.


 


1.2   Interest.



 


(a)   Interest
shall accrue hereunder at a rate equal to 4.5% per annum (or, if less, the highest amount permitted by law) (such interest shall be referred
to as “Interest” and such rate, the “Interest Rate”) on the Principal hereof and shall be due and
payable quarterly in arrears, commencing on March 31, 2023, on each March 31, June 30, September 30 and December 31 during the term of
this Advance Note (each, an “Interest Payment Date”), up to and including the final Interest Payment Date, which shall
be the Maturity Date, for the period (each, an “Interest Period”) (i) initially, commencing on and including the Original
Issuance Date and ending on and including March 31, 2023 and (ii) thereafter, commencing on and including the date that is one day after
the immediately preceding Interest Payment Date and ending on and including the last day of the third succeeding calendar month thereafter
(or, with respect to the Interest Payment Date that is the Maturity Date, ending on and including the Maturity Date). In the event of
any conversion of all or any portion of the Principal into Common Stock in accordance with the terms hereof during any Interest Period,
(i) Interest shall accrue at the Interest Rate on the outstanding Principal to and including the date of conversion and (ii) from and
after any date of conversion, Interest shall accrue on the then outstanding Principal to and including the succeeding date of conversion
(and in each case, on the then outstanding Principal thereafter) or, if earlier, the applicable Interest Payment Date.


 






    A-1


     


    

 


(b)   Interest
due on each Interest Payment Date shall be payable by the Company, at the Company’s option, (i) in kind, through the issuance of
a PIK Advance Note to the Holder in an aggregate principal amount equal to the amount of Interest due on such Interest Payment Date, in
accordance with (A) if the Equity Conditions are satisfied as of such Interest Payment Date, clause (2) below and (B) if the Equity Conditions
are not satisfied as of such Interest Payment Date or the Company is otherwise unable to issue a Registered PIK Advance Note to the Holder,
clause (3) below, or (ii) in cash.


 


(1)   In
the event the Company shall determine to pay Interest due on any Interest Payment Date through the issuance to the Holder of a PIK Advance
Note, the Company shall notify the Holder (which notice may be via e-mail) at least five Business Days prior to the applicable Interest
Payment Date (a “PIK Election Notice”).


 


(2) Subject to
the satisfaction of the Equity Conditions at such time, the Company may issue PIK Advance Notes to the Holder on a registered basis
(a “Registered PIK Advance Note”) in an aggregate principal amount equal to the amount of Interest that will become due
on such Interest Payment Date, in satisfaction thereof, under this Advance Note and any Other Advance Note (as defined below) [or
Prepaid-Tranche] then held by the Holder with respect to which the Company has elected to pay interest in kind in accordance with
the terms thereof (which aggregate amount shall be rounded up to the nearest whole dollar) and the Underlying Shares thereof,
pursuant to which the Holder shall receive freely tradeable shares of Common Stock on any conversion, at the discretion of the
Holder, of such PIK Advance Note. Prior to the open of trading on the Interest Payment Date on which such Interest would become due,
the Company shall file a prospectus supplement to its Form S-3 with the Commission covering the issuance to the Holder (and any
other holder of Closing Advance Notes or Prepaid-Tranches with respect to which the Company has elected to, and is then entitled to,
pay interest through the issuance of Registered PIK Advance Notes) of such Registered PIK Advance Note. Each Registered PIK Advance
Note shall be in the form of and on the same terms and conditions as a Registered Advance Note, other than the aggregate principal
amount thereof; provided, that, (i) such PIK Advance Note shall not bear any interest and (ii) the maturity date of
such PIK Advance Note shall be the Maturity Date. Notwithstanding any PIK Election Notice delivered by the Company, if the Equity
Conditions are not satisfied on any Interest Payment Date, the Company shall not have the right to issue a Registered PIK Advance
Note to the Holder.


 


(3) If the
Company is unable to issue a Registered PIK Advance Note to the Holder in accordance with clause (2) above, the Company may issue
PIK Advance Notes to the Holder on a private placement basis, pursuant to Section 4(a)(2) of the Securities Act, and Rule 506(b)
promulgated thereunder (a “Private Placement PIK Advance Note”) in an aggregate principal amount equal to the
amount of Interest that will become due on such Interest Payment Date, in satisfaction thereof, under this Advance Note and any
Other Advance Note  [or Prepaid-Tranche] then held by the Holder with respect to which the Company has elected to
pay interest in kind in accordance with the terms thereof (which aggregate amount shall be rounded up to the nearest whole dollar).
Each Private Placement PIK Advance Note shall be in the form of and on the same terms and conditions as a Private Placement Advance
Note, other than the aggregate principal amount thereof; provided, that, (i) the outstanding principal amount of such
Private Placement PIK Advance Note shall bear Interest at the Interest Rate, which amount shall be payable in kind and capitalized
to the outstanding principal amount of the Private Placement PIK Advance Note on each Interest Payment Date, which principal amount
(including any such capitalized interest) shall be payable in cash at the maturity date of such Private Placement PIK Advance Note,
(ii) the outstanding principal amount of such Private Placement PIK Advance Note (including any such capitalized interest) shall be
convertible into Common Stock in accordance with the terms of the Private Placement Advance Note and (ii) the maturity date of such
Private Placement PIK Advance Note shall be the Maturity Date.


 






    A-2


     


    

 


(4)   Any
PIK Advance Notes issued to the Holder hereunder will be considered to be part of the same series of, and rank equally and ratably with,
this Advance Note.


 


(c)   From
and after the occurrence and during the continuance of any Event of Default, interest shall accrue hereunder at a rate equal to 12% per
annum (or, if less, the highest amount permitted by law) (such interest upon an Event of Default shall be referred to as “Default
Interest”) and shall be due and payable in cash on the first Trading Day of each calendar month during the continuance of such
Event of Default (a “Default Interest Payment Date”). In the event that such Event of Default is subsequently cured
(and no other Event of Default then exists (including, without limitation, for the Company’s failure to pay such Default Interest
on the applicable Default Interest Payment Date)), the Default Interest shall cease to accrue hereunder as of the day immediately following
the date of such cure; provided that the Interest as calculated and unpaid at such increased rate during the continuance of such
Event of Default shall continue to apply to the extent relating to the days after the occurrence of such Event of Default through and
including the date of such cure of such Event of Default. Interest and Default Interest shall accrue based on a 360-day year composed
of twelve 30-day months and, for partial months, on the basis of the number of days actually elapsed in a 30-day month.


 


1.3 Prepayment. If
following the Original Issuance Date while this Advance Note is outstanding the Company directly or indirectly receives proceeds from
and closes any Subsequent Financing (other than any Permitted Private Placement Financing or Exempt Issuance), the Company shall give
written notice to the Holder within two Trading Days, and the Holder within five Trading Days after receipt of such written notice may
request a prepayment of Principal and any accrued and unpaid Interest thereon (if any) in an amount up to the Holder’s pro rata
portion (based on the ratio of (a) the Principal of this Advance Note for such Purchaser to (b) the sum of the aggregate Principal of
all Advance Notes made to the Purchasers under the Purchase Agreement) of 30% of the gross proceeds received by the Company from such
Subsequent Financing. Except as otherwise provided elsewhere in the Purchase Agreement or this Advance Note, the Company may not prepay
any portion of the Principal.


 


1.4   Payment
on Non-Trading Days. Whenever any payment to be made on this Advance Note shall be due on a day which is not a Trading Day, such payment
may be due on the next succeeding Trading Day.


 


1.5   Replacement.
Upon receipt of a duly executed Affidavit of Loss and Indemnity Agreement in customary form from the Holder with respect to the loss,
theft or destruction of this Advance Note (or any replacement hereof), or, in the case of a mutilation of this Advance Note, upon surrender
and cancellation of such Advance Note, the Company shall issue a new Advance Note, of like tenor and amount, in lieu of such lost, stolen,
destroyed or mutilated Advance Note.


 


1.6   Status
of Advance Note. The obligations of the Company under this Advance Note shall rank senior to all other existing Indebtedness and equity
of the Company, other than the amounts owing to the holders under the other Closing Advance Notes (each, an “Other Advance Note”)
and the Prepaid-Tranches, when issued, to the extent of the first lien security interest in the collateral per the Security Agreement,
and, to the extent applicable, any Permitted Indebtedness or other Indebtedness secured by Permitted Liens. The obligations of the Company
under this Advance Note shall rank pari passu with the amounts owing to the other Purchasers under the Other Advance Notes and
with the amounts owing under any then-outstanding Prepaid-Tranches. Upon any Liquidation Event (as hereinafter defined), but subject in
all cases to the Purchase Agreement, the Holder will be entitled to receive, before any distribution or payment is made upon, or set apart
with respect to, any Indebtedness of the Company (other than the Other Advance Notes) or any class of capital stock of the Company, an
amount equal to the outstanding Principal, Interest and any other sums due hereunder. For purposes of this Advance Note, “Liquidation
Event” means a liquidation pursuant to a filing of a petition for bankruptcy under applicable law or any other insolvency or
debtor’s relief, an assignment for the benefit of creditors, or a voluntary or involuntary liquidation, dissolution or winding up
of the affairs of the Company.

that itemized Events of Default other than Section 2.1(b) were inserted at the request of the Holder for convenience and such itemization
does not modify Section 2.1(b) nor create any additional remedies for the Holder.


 


2.2   Remedies
Upon an Event of Default.


 


(a)   Upon
the occurrence of any Event of Default that has not been remedied or waived within three Trading Days or, with respect to the Event of
Default described in Section 2.1(h), two Trading Days (provided, however, that there shall be no cure period for an Event
of Default described in Section 2.1(j), 2.1(k) or 2.1(l)), the Company shall be obligated to pay to the Holder the Mandatory Default Amount,
which Mandatory Default Amount shall be immediately due and payable to the Holder, anything contained in any Transaction Document to the
contrary notwithstanding. In the event this Advance Note shall be converted under an Event of Default, prior to (and in place of) any
payment of the Mandatory Default Amount to the Holder, the Holder shall have the option to convert the aggregate outstanding Principal
of this Advance Note at the Alternative Conversion Price (provided that all payments shall be subject to the provisions of the Purchase
Agreement with respect to the holders of the Other Advance Notes). For this purpose, the Holder shall have the option to have the Alternative
Conversion Price determined as of the date the Notice of Conversion for such conversion is delivered by the Holder to the Company, rather
than the date of such Event of Default.


 


(b)   Upon
the occurrence of any Event of Default, the Company shall, as promptly as possible but in any event within two Trading Days of the occurrence
of such Event of Default, notify the Holder of the occurrence of such Event of Default, describing the event or factual situation giving
rise to the Event of Default and specifying the relevant subsection or subsections of Section 2.1 hereof under which such Event of Default
has occurred.


 


(c)   The
provisions of Section 3.2(b) and (c) shall also apply upon any Events of Default relating to Conversion Shares in addition to the remedies
under this Section 2.2.


 


(d)   Any
Event of Default hereunder may be waived upon the mutual agreement of the Parties.

3.1   Conversion.


 


(a)   Conversion.
At any time after the Original Issuance Date, this Advance Note shall be convertible (in whole or in part) at the option of the Holder
into such number of fully paid and non-assessable shares of Common Stock as is determined by dividing (x) that portion of the outstanding
Principal and any accrued and unpaid Interest thereon that the Holder elects to convert (the “Conversion Amount”) by
(y) the Conversion Price (as hereinafter defined) then in effect on the date on which the Holder delivers to the Company a notice of conversion
in substantially the form attached hereto as Exhibit A (the “Notice of Conversion”) in accordance with Section
5.1. The Holder shall deliver this Advance Note to the Company at the address designated in the Purchase Agreement at such time that this
Advance Note is fully converted. With respect to partial conversions of this Advance Note, the Company shall keep written records of the
amount of this Advance Note converted as of the date of such conversion (each, a “Conversion Date”).


 






    A-7


     


    

 


(b)   Conversion
Price.


 


(i)   The
“Conversion Price” means the lesser of (i) the average of the preceding five daily VWAPs calculated using the last
Trading Day prior to the Initial Closing [or, in the case of any Pre-Paid Tranche, any Monthly Closing, as the case may be,] times 130%
(the “Fixed Conversion Price”), which Fixed Conversion Price shall be subject to adjustment as provided herein, or
(ii) 92.5% of the average of the three lowest daily VWAPs during the prior 10 Trading Days ending on the last Trading Day prior to the
delivery of a Notice of Conversion by the Holder (or the same Trading Day, if the Notice of Conversion is delivered after the close of
trading on the Principal Market on such date) (the “Variable Conversion Price”).


 


(ii)   At
any time the Company receives a Note of Conversion at a time that the Conversion Price (or, as applicable, the Alternative Conversion
Price) then in effect, without regard to the Floor Price (the “Applicable Conversion Price”), is less than the Floor
Price then in effect (unless such Floor Price is lowered with the written consent of the Company and the Holder of this Advance Note,
which may be an e-mail), the Company shall issue a number of shares equal to the Conversion Amount divided by such Floor Price and pay
the economic difference between the Applicable Conversion Price and such Floor Price in cash. For further clarification, the economic
difference shall be equal to (A) the number of shares that would have been delivered using the Applicable Conversion Price, minus (B)
the number of shares delivered using the Floor Price multiplied by (C) the daily VWAP of the Common Stock on the Conversion Date ((A-B)*C).
The failure to pay any cash due in connection with a conversion shall be deemed an Event of Default, subject to Section 2.2(a). 


 


(c)   Voluntary
Adjustment of Fixed Conversion Price. Subject to the rules and regulations of the Principal Market, the Company may at any time during
the term of this Advance Note, with the prior written consent of the Required Holders, reduce the then current Fixed Conversion Price
of each of the Advance Notes to any amount and for any period of time deemed appropriate by the board of directors of the Company.


 


3.2   Delivery
of Conversion Shares. 


 


(a)   As
soon as practicable after any conversion or payment of any amount due hereunder in the form of shares of Common Stock in accordance with
this Advance Note, and in any event within the earlier of (i) two (2) Trading Days following the delivery of the Notice of Conversion
and (ii) the expiration of the Standard Settlement Period thereafter (such date, the “Share Delivery Date”), the Company
shall, at its expense, cause to be issued in the name of and delivered to the Holder, or as the Holder may direct, the number of shares
of fully paid and non-assessable Common Stock to which the Holder shall be entitled on such conversion or payment (the “Conversion
Shares”), which Conversion Shares shall be free of restrictive and trading legends and delivered electronically to the Holder
(or its designee), by crediting the account of the Holder’s (or such designee’s) broker with DTC through its Deposit Withdrawal
At Custodian system as instructed by the Holder (or its designee).


 


(b)   Obligation
Absolute. The Company’s obligations to issue and deliver the Conversion Shares upon conversion of this Advance Note in accordance
with the terms hereof are absolute and unconditional, irrespective of any action or inaction by the Holder to enforce the same, any waiver
or consent with respect to any provision hereof (other than any express written waiver by the Holder entitled to receive such Conversion
Shares of the obligation to issue and deliver the same), the recovery of any judgment against any Person or any action to enforce the
same, or any setoff, counterclaim, recoupment, limitation or termination, or any breach or alleged breach by the Holder or any other Person
of any obligation to the Company or any violation or alleged violation of law by the Holder or any other Person, and irrespective of any
other circumstance which might otherwise limit such obligation of the Company to the Holder in connection with the issuance of such Conversion
Shares (other than any such limitation expressly set forth in the Transaction Documents); provided, however, that such delivery
shall not operate as a waiver by the Company of any such action the Company may have against the Holder. In the event the Holder of this
Advance Note shall elect to convert any or all of the outstanding Principal and any accrued and unpaid Interest thereon hereof, the Company
may not refuse conversion based on any claim that the Holder or anyone associated or affiliated with the Holder has been engaged in any
violation of law, agreement or for any other reason, unless an injunction from a court, on notice to Holder, restraining and or enjoining
conversion of all or part of this Advance Note shall have been sought and obtained, and the Company posts a surety bond for the benefit
of the Holder in the amount of 100% of the outstanding Principal of this Advance Note and any accrued and unpaid Interest thereon, which
is subject to the injunction, which bond shall remain in effect until the completion of litigation of the underlying dispute and the proceeds
of which shall be payable to the Holder to the extent it obtains a favorable judgment, with any amount of the surety bond in excess of
any such money judgment to be applied as a repayment of such outstanding Principal and accrued and unpaid interest thereon and other amounts
then payable by the Company to the Holder under this Advance Note. In the absence of such injunction, the Company shall issue the Conversion
Shares or, if applicable, cash, upon delivery of a Notice of Conversion on the terms set forth in this Advance Note.


 






    A-8


     


    

 


(c) The Company’s Failure
to Timely Convert. If the Company shall fail for any reason or for no reason, on or prior to the applicable Share Delivery Date,
to credit the balance account of the Holder or the Holder’s designee with DTC for such number of Conversion Shares to which the
Holder is entitled upon the Holder’s conversion of this Advance Note, as the case may be (in each case, other than to the extent
such failure arose from any action taken or not taken by the Holder or its designee with DTC) (a “Conversion Failure”),
then, in addition to all other remedies available to the Holder, the Holder may by notice to the Company (in lieu of receiving such Conversion
Shares subject to such Conversion Failure), require the Company to either, at the Holder’s option, (1) redeem, in cash, the Conversion
Amount in such Conversion Failure at a redemption price equal to the product of (i) the number of shares of Common Stock subject to such
Conversion Failure multiplied by (ii) the VWAP on the date of the Notice of Conversion (the “Mandatory Prepayment Price”);
provided that, notwithstanding anything in this Advance Note or the Purchase Agreement to the contrary, the payment of the Mandatory
Prepayment Price shall cure any breach or Event of Default arising from such Conversion Failure, or (2) pay to the Holder in cash, as
liquidated damages and not as a penalty, for each $1,000 of Principal being converted, $5 per Trading Day (increasing to $10 per Trading
Day on the fifth (5th) Trading Day after such liquidated damages begin to accrue) for each Trading Day after such Share Delivery
Date until such Conversion Shares are delivered or Holder rescinds such conversion. In addition to the foregoing, if on or prior to the
Share Delivery Date, if 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 conversion hereunder (in each case,
other than to the extent such failure arose from any action taken or not taken by the Holder or its designee with DTC), and if on or
after such Share Delivery Date the Holder acquires (in an open market transaction or otherwise) shares of Common Stock to deliver in
satisfaction of a sale by the Holder of all or any portion of the number of shares of Common Stock issuable upon such conversion that
the Holder is entitled to receive from the Company and has not received from the Company in connection with such Conversion Failure (a
“Buy-In”), the “Buy-In” provisions of Section 4.1(d) of the Purchase Agreement shall apply in accordance
with the terms thereof. 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 conversion of this Advance Note as required pursuant to the terms hereof.


 


(d) Pro Rata
Conversion; Disputes. In the event that the Company receives a Notice of Conversion from the Holder, the holders of the Other
Advance Notes or of any Prepaid-Tranches or Warrant and/or any holders of options, or other convertible securities for the same
Conversion Date and the Company can convert some, but not all, of such portions of the Closing Advance Notes, Prepaid-Tranches,
Warrants, options or other convertible securities submitted for conversion, the Company, subject to this Section 3.2(d), shall (i)
first convert the entire Conversion Amount submitted for conversion on such date by the Holder and the holders of the Other Advance
Notes and of any Prepaid-Tranches, if any, or Warrants on a pro rata basis, and (ii) shall thereafter convert from each holder of
options or other convertible securities electing to have options, warrants or other convertible securities converted on such date
(other than the Closing Advance Notes, Prepaid-Tranches or Warrants) a pro rata amount of such holder’s portion of its options
or other convertible securities submitted for conversion based on the aggregate number of shares of Common Stock issuable upon
exercise (or conversion) of all options or other convertible securities submitted for conversion on such date (not including the
Closing Advance Notes and Prepaid-Tranches).


 






    A-9


     


    

 


(e)   Beneficial
Ownership Limitation. The Company shall not effect the conversion of any portion of this Advance Note [or any Prepaid-Tranche] (or
the exercise of any Warrants), and the Holder shall not have the right to convert any portion of this Advance Note or any Other Advance
Note [or any Prepaid-Tranche] pursuant to the terms and conditions of this Advance Note or any Other Advance Note [or any Prepaid-Tranche]
(or the exercise of any Warrants) and any such conversion shall be null and void and treated as if never made, to the extent that after
giving effect to such conversion or 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 conversion. 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 conversion of this Advance Note or any Other Advance Note [or any Prepaid-Tranche]
(or the exercise of any Warrants) 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) conversion of the remaining, non-converted portion of this Advance Note or any Other Advance
Note [or any Prepaid-Tranche] (or the exercise of any Warrants) beneficially owned by the Holder or any of the other Attribution Parties
and (B) exercise or conversion of the unexercised or non-converted portion of any other securities of the Company (including, without
limitation, any convertible notes or convertible preferred stock or warrants, including, without limitation, the 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 3.2(e). For purposes of this Section 3.2(e), beneficial ownership shall be calculated in accordance with Section 13(d)
of the Exchange Act. For purposes of determining the number of outstanding shares of Common Stock the Holder may acquire upon the
conversion of this Advance Note [or any Prepaid-Tranche] (or exercise of any Warrants) 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 a Notice
of Conversion 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 notify the Holder in writing of the number of shares of Common Stock then outstanding and, to the extent
that such Notice of Conversion would otherwise cause the Holder’s beneficial ownership, as determined pursuant to this Section 3.2(e),
to exceed the Maximum Percentage, the Holder must notify the Company of a reduced number of shares of Common Stock to be purchased pursuant
to such Notice of Conversion. For any reason at any time, upon the written or oral request of the Holder, the Company shall within
one Trading 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 Advance Note or any Other Advance Note [or any Prepaid-Tranche] (or the exercise of any Warrants),
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 conversion of this Advance Note or any Other Advance Note [or
any Prepaid-Tranche] (or the exercise of any Warrants) 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 Exchange 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. To the extent that the limitation
contained in this Section 3.2(e) applies, the determination of whether and what portion of this Advance Note may be converted into shares
of Common Stock (in relation to other securities owned by the Holder together with any Affiliates and Attribution Parties) and of which
portion of this Advance Note is convertible at any given time shall be in the sole discretion of the Holder, and the submission of a Notice
of Conversion shall be deemed to be the Holder’s determination of whether and for what amount of shares of Common Stock this Advance
Note is convertible at such time (in relation to other securities owned by the Holder together with any Affiliates and Attribution Parties),
in each case subject to the Beneficial Ownership Limitation, and the Company shall have no obligation to verify or confirm the accuracy
of such determination. Provided, however, the Company shall indemnify the Holder in accordance with the Purchase Agreement
for any damages the Holder may sustain as the result of Excess Shares being issued due to an error of the Transfer Agent or any replacement
transfer agent. Upon delivery of a written notice to the Company, the Holder may from time to time increase (with such increase not effective
until the 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 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 an Advance Note 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 Advance Note or any Other Advance Note [or any Prepaid-Tranche] (or
the exercise of any Warrants) 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 Exchange Act. No prior inability to convert this Advance Note
pursuant to this Section 3.2(e) shall have any effect on the applicability of the provisions of this Section 3.2(e) with respect to any
subsequent determination of convertibility. The provisions of this paragraph shall not be construed and implemented in a manner
otherwise than in strict conformity with the terms of this Section 3.2(e) to the extent necessary to correct any provision hereof which
may be defective or inconsistent with the intended beneficial ownership limitation contained in this Section 3.2(e) or to make changes
or supplements necessary or desirable to properly give effect to such limitation. The limitation contained in this Section 3.2(e)
may not be waived and shall apply to a successor holder of this Advance Note.

3.3 Adjustment
of Fixed Conversion Price. 


 


(a) Until
this Advance Note has been paid in full or converted in full, the Fixed Conversion Price shall be subject to adjustment from time-to-time
as follows (but shall not be increased, other than pursuant to a combination):


 


(i) Adjustments
for Stock Splits and Combinations. If the Company shall at any time or from time-to-time after the Original Issuance Date effect a
split of the outstanding Common Stock or pay a dividend in Common Stock to holders of its Common Stock, the applicable Fixed Conversion
Price in effect immediately prior to the stock split shall be proportionately decreased. If the Company shall at any time or from time-to-time
after the Original Issuance Date, combine the outstanding Common Stock into a lesser number of shares, the applicable Fixed Conversion
Price in effect immediately prior to the combination shall be proportionately increased. Any adjustments under this Section 3.3(a)(i)
shall be effective at the close of business on the date the stock split, stock dividend, or combination occurs. 


 


(ii) Adjustments
for Certain Dividends and Distributions. If the Company shall at any time or from time-to-time after the Original Issuance Date make
or issue or set a record date for the determination of holders of Common Stock entitled to receive a dividend or other distribution payable
in Common Stock, then, and in each event, the applicable Fixed Conversion Price in effect immediately prior to such event shall be decreased
as of the time of such issuance or, in the event such record date shall have been fixed, as of the close of business on such record date,
by multiplying the applicable Fixed Conversion Price then in effect by a fraction:


 


(1) the
numerator of which shall be the total number of shares of Common Stock issued and outstanding immediately prior to the time of such issuance
or the close of business on such record date; and


 


(2) the
denominator of which shall be the total number of shares of Common Stock issued and outstanding immediately prior to the time of such
issuance or the close of business on such record date plus the number of Common Stock issuable in payment of such dividend or distribution;


 


provided, however,
that, if the Company shall at any time set a record date for the determination of holders of Common Stock entitled to receive a dividend
or other distribution payable in Common Stock and (A) such dividend is not fully paid or if such distribution is not fully made on the
date fixed therefor, the Fixed Conversion Price shall be adjusted pursuant to this Section 3.3(a)(ii) as of the time of actual payment
of such dividends or distributions or (B) the Company shall subsequently rescind or otherwise cancel or determine not to make such dividend
or distribution, then any adjustment to the Fixed Conversion Price made pursuant to this clause (ii) with respect to the fixing of such
record date shall be reversed and of no further force or effect as of the date of the Company’s public announcement that it is rescinding
or otherwise canceling or determining not making such dividend or distribution.


 


(iii) Adjustment
for Other Dividends and Distributions. If the Company shall at any time or from time-to-time after the Original Issuance Date make
or issue a dividend or other distribution payable in other Common Stock, securities of the Company, securities of another entity or other
assets, then, and in each event, the Holder of this Advance Note shall receive upon conversions hereof, in addition to the number of shares
of Common Stock receivable thereon, the number of securities of the Company or other issuer (as applicable) or other property that it
would have received had this Advance Note been converted into Common Stock in full (without regard to any conversion limitations herein)
on the date of such event and had thereafter, during the period from the date of such event to and including the Conversion Date, retained
such securities (together with any distributions payable thereon during such period) or assets, giving application to all adjustments
called for during such period under this Section 3.3(a)(iii) with respect to the rights of the holders of this Advance Note.


 






    A-11


     


    

 


(iv) Adjustments
for Reclassification, Exchange or Substitution. If the Common Stock at any time or from time to time after the Original Issuance Date
shall be changed to the same or different number of shares or other securities of any class or classes of stock or other property, whether
by reclassification, exchange, substitution or otherwise (other than by way of a stock split or combination of shares or stock dividends
or other distributions provided for in Sections 3.3(a)(i), (ii) and (iii) hereof), then, and in each event, an appropriate revision to
the Fixed Conversion Price shall be made and provisions shall be made (by adjustments of the Fixed Conversion Price or otherwise) so that
the Holder shall have the right thereafter to convert this Advance Note into the kind and amount of shares of stock or other securities
or other property receivable upon reclassification, exchange, substitution or other change, by holders of the number of shares of Common
Stock into which such Advance Note might have been converted immediately prior to such reclassification, exchange, substitution or other
change, all subject to further adjustment as provided herein.


 


(v) Rights
Upon Issuance of Other Securities.


 


(1) Adjustment
of Fixed Conversion Price upon Issuance of Common Stock. If and whenever on or after the Original Issuance Date the Company issues
or sells, or in accordance with this Section 3.3(a) is deemed to have issued or sold, any shares of Common Stock (including the issuance
or sale of shares of Common Stock owned or held by or for the account of the Company, but excluding any Exempt Issuance (other than clause
(d) of the definition of Exempt Issuance in the Purchase Agreement which shall not be deemed to be an Exempt Issuance for purposes of
this Section 3.3(a)(v) issued or sold or deemed to have been issued or sold) for a consideration per share (the “Dilutive Issuance
Price”) less than a price equal to the Fixed Conversion Price in effect immediately prior to such issuance or sale or deemed
issuance or sale (such Fixed Conversion Price then in effect is referred to herein as the “Applicable Price”) (the foregoing
a “Dilutive Issuance”), then, immediately after such Dilutive Issuance, the Fixed Conversion Price then in effect shall
be reduced to the lower of (i) an amount equal to the Dilutive Issuance Price, or (ii) the VWAP on the Trading Day following the first
public disclosure of the Dilutive Issuance (other than clause (d) of the definition of Exempt Issuance in the Purchase Agreement which
shall not be deemed to be an Exempt Issuance for purposes of this Section 3.3(a)(v)). For the purposes of this Section 3.3(a)(v), the
next Trading Day if an announcement is made before 4:00 pm New York, N.Y. time is either the day of the announcement or the following
Trading Day. For all purposes of the foregoing (including, without limitation, determining the adjusted Fixed Conversion Price and the
Dilutive Issuance Price under this Section 3.3(a)(v)), the following shall be applicable:


 


(2) Issuance
of Options. If the Company in any manner grants or sells any options or rights to acquire Common Stock or Convertible Securities (“Options”)
(other than pursuant to any Exempt Issuance) and the lowest price per share for which one share of Common Stock is at any time issuable
upon the exercise of any such Option or upon conversion, exercise or exchange of any Convertible Securities issuable upon exercise of
any such Option or otherwise pursuant to the terms thereof is less than the Applicable Price, then such share of Common Stock shall be
deemed to be outstanding and to have been issued and sold by the Company at the time of the granting or sale of such Option for such price
per share, excluding any transactions involving an Exempt Issuance. For purposes of this Section 3.3(a)(v) the “lowest price per
share for which one share of Common Stock is at any time issuable upon the exercise of any such Option or upon conversion, exercise or
exchange of any Convertible Securities issuable upon exercise of any such Option or otherwise pursuant to the terms thereof” shall
be equal to (1) the lower of (x) the sum of the lowest amounts of consideration (if any) received or receivable by the Company with respect
to any one share of Common Stock upon the granting or sale of such Option, upon exercise of such Option and upon conversion, exercise
or exchange of any Convertible Security issuable upon exercise of such Option or otherwise pursuant to the terms thereof and (y) the lowest
exercise price set forth in such Option for which one share of Common Stock is issuable (or may become issuable assuming all possible
market conditions) upon the exercise of any such Options or upon conversion, exercise or exchange of any Convertible Securities issuable
upon exercise of any such Option or otherwise pursuant to the terms thereof, minus (2) (x) the sum of all amounts paid or payable to the
holder of such Option (or any other Person) upon the granting or sale of such Option, upon exercise of such Option and upon conversion,
exercise or exchange of any Convertible Security issuable upon exercise of such Option or otherwise pursuant to the terms thereof plus
the value of any other consideration received or receivable by, or benefit conferred on, the holder of such Option (or any other Person)
divided by (y) the number of shares of Common Stock issuable upon exercise of such Option or upon conversion, exercise or exchange of
any Convertible Security issuable upon exercise of such Option. Except as contemplated below, no further adjustment of the Fixed Conversion
Price shall be made upon the actual issuance of such share of Common Stock or of such Convertible Securities upon the exercise of such
Options or otherwise pursuant to the terms thereof or upon the actual issuance of such shares of Common Stock upon conversion, exercise
or exchange of such Convertible Securities.


 






    A-12


     


    

 


(3) Issuance
of Convertible Securities. If the Company in any manner issues or sells any Convertible Securities and the lowest price per share
for which one share of Common Stock is at any time issuable upon the conversion, exercise or exchange thereof or otherwise pursuant to
the terms thereof is less than the Applicable Price, then such share of Common Stock shall be deemed to be outstanding and to have been
issued and sold by the Company at the time of the issuance or sale of such Convertible Securities for such price per share. For the purposes
of this Section 3.3(a)(v), the “lowest price per share for which one share of Common Stock is at any time issuable upon the conversion,
exercise or exchange thereof or otherwise pursuant to the terms thereof” shall be equal to (A) the lower of (x) the sum of the lowest
amounts of consideration (if any) received or receivable by the Company with respect to one share of Common Stock upon the issuance or
sale of the Convertible Security and upon conversion, exercise or exchange of such Convertible Security or otherwise pursuant to the terms
thereof and (y) the lowest Conversion Price set forth in such Convertible Security for which one share of Common Stock is issuable (or
may become issuable assuming all possible market conditions) upon conversion, exercise or exchange thereof or otherwise pursuant to the
terms thereof minus (B) (x) the sum of all amounts paid or payable to the holder of such Convertible Security (or any other Person) upon
the issuance or sale of such Convertible Security plus the value of any other consideration received or receivable by, or benefit conferred
on, the holder of such Convertible Security (or any other Person) divided by (y) the number of shares of Common Stock issuable upon conversion,
exercise or exchange of such Convertible Security. Except as contemplated below, no further adjustment of the Fixed Conversion Price shall
be made upon the actual issuance of such shares of Common Stock upon conversion, exercise or exchange of such Convertible Securities or
otherwise pursuant to the terms thereof, and if any such issuance or sale of such Convertible Securities is made upon exercise of any
Options for which adjustment of the Fixed Conversion Price has been or is to be made pursuant to other provisions of this Section 3.3(a)(v),
except as contemplated below, no further adjustment of the Fixed Conversion Price shall be made by reason of such issuance or sale.


 


(4) Change
in Option Price or Rate of Conversion. If the purchase or exercise price provided for in any Options, the additional consideration,
if any, payable upon the issue, conversion, exercise or exchange of any Convertible Securities, or the rate at which any Convertible Securities
are convertible into or exercisable or exchangeable for shares of Common Stock decreases at any time (other than proportional changes
in connection with an event referred to Section 3.3(a)(i) above), the Fixed Conversion Price in effect at the time of such decrease shall
be adjusted to the Fixed Conversion Price which would have been in effect at such time had such Options or Convertible Securities provided
for such decreased purchase price, additional consideration or decreased conversion rate (as the case may be) at the time initially granted,
issued or sold. For purposes of this Section 3.3(a)(v), if the terms of any Option or Convertible Security that was outstanding as of
the Issuance Date are decreased in the manner described in the immediately preceding sentence, then such Option or Convertible Security
and the shares of Common Stock deemed issuable upon exercise, conversion or exchange thereof shall be deemed to have been issued as of
the date of such decrease. No adjustment pursuant to this Section 3.3(a)(v) shall be made if such adjustment would result in an increase
of the Fixed Conversion Price then in effect.


 


(5) Issuances
of Units. In case any Options or Convertible Securities are issued in connection with the issue or sale of other securities of the
Company, together comprising one integrated transaction, at a price per unit that is less than the Applicable Price, then the shares of
Common Stock issuable upon the exercise of any such Option or upon conversion, exercise or exchange of any Convertible Securities issued
or sold in such integrated transaction shall be deemed to have been issued or sold by the Company at the time of the issuance or sale
of such Convertible Securities for such price per unit and, immediately after such issuance, the Fixed Conversion Price then in effect
shall be reduced to the lower of (i) an amount equal to the price per unit issuable in such transaction, or (ii) the lowest VWAP of the
Common Stock over the five Trading Days following the first public disclosure of such transaction. Any indebtedness shall be valued at
the principal less any original issue discount. If multiple shares of Common Stock are contained in a unit, the aggregate consideration
shall be divided by the number of shares of Common Stock in a unit. If any shares of Common Stock or Options or Convertible Securities
are issued or sold or deemed to have been issued or sold for cash, the amount of such consideration received by the Company will be deemed
to be the net amount received by the Company therefor. If any shares of Common Stock or Options or Convertible Securities are issued or
sold for a consideration other than cash, the amount of such consideration received by the Company will be the fair value of such consideration,
except where such consideration consists of publicly traded securities, in which case the amount of consideration received by the Company
will be the VWAP of such public traded securities on the date of receipt. If any shares of Common Stock or Options or Convertible Securities
are issued to the owners of the non-surviving entity in connection with any merger in which the Company is the surviving entity, the amount
of consideration therefor will be deemed to be the fair value of such portion of the net assets and business of the non-surviving entity
as is attributable to such shares of Common Stock or Options or Convertible Securities, as the case may be. No further adjustment of the
Fixed Conversion Price shall be made upon the actual issuance of such shares of Common Stock or of such Convertible Securities upon the
exercise of such Options or Convertible Securities or otherwise pursuant to the terms thereof.


 






    A-13


     


    

 


(6) Record
Date. If the Company takes a record of the holders of shares of Common Stock for the purpose of entitling them (A) to receive a dividend
or other distribution payable in shares of Common Stock, Options or in Convertible Securities or (B) to subscribe for or purchase shares
of Common Stock, Options or Convertible Securities, then such record date will be deemed to be the date of the issuance or sale of the
shares of Common Stock deemed to have been issued or sold upon the declaration of such dividend or the making of such other distribution
or the date of the granting of such right of subscription or purchase (as the case may be); provided, however, that, if
the Company shall at any time set a record date for the determination of holders of Common Stock entitled to receive a dividend or other
distribution payable in shares of Common Stock, Options or in Convertible Securities or to subscribe for or purchase shares of Common
Stock, Options or in Convertible Securities and (A) such dividend is not fully paid or if such distribution is not fully made, or the
subscription rights are not fully granted, on the date fixed therefor, the Fixed Conversion Price shall be adjusted pursuant to this Section
3.3(a)(v) as of the time of actual payment of such dividends or distributions or the effectiveness of such subscription rights or (B)
the Company shall subsequently rescind or otherwise cancel or determine not to make such dividend or distribution or to grant such subscription
rights, then any adjustment to the Fixed Conversion Price made pursuant to this Section 3.3(a)(v) with respect to the fixing of such record
date shall be reversed and of no further force or effect as of the date of the Company’s public announcement that it is rescinding
or otherwise canceling or determining not making such dividend or distribution or the grant of such subscription rights.


 


(b) Fractional
Shares. The Company shall not issue any fraction of a share of Common Stock upon any conversion. If the issuance would result in the
issuance of a fraction of a share of Common Stock, the Company shall round such fraction of a share of Common Stock to the nearest whole
share. If any adjustments to the Fixed Conversion Price under this Section 3.3 result in a fractional amount, the fractional amount rounded
to the nearest whole cent.


 


(c) No
Impairment. The Company shall not, by amendment of its Articles or Certificate of Incorporation or through any reorganization, transfer
of assets, consolidation, merger, dissolution, issue or sale of securities or any other voluntary action, avoid or seek to avoid the observance
or performance of any of the terms to be observed or performed hereunder by the Company, but will at all times in good faith assist in
the carrying out of all the provisions of this Section 3.3 and in the taking of all such action as may be necessary or appropriate in
order to protect the conversion rights of the Holder against impairment.


 


(d) Certificates
as to Adjustments. Upon occurrence of each adjustment or readjustment of the Fixed Conversion Price or number of shares of Common
Stock issuable upon conversion of this Advance Note pursuant to this Section 3.3, the Company at its expense shall promptly compute such
adjustment or readjustment in accordance with the terms hereof and furnish to the Holder a certificate setting forth such adjustment and
readjustment, showing in detail the facts upon which such adjustment or readjustment is based. The Company shall, upon written request
of the Holder, at any time, furnish or cause to be furnished to the Holder a like certificate setting forth such adjustments and readjustments,
the applicable Fixed Conversion Price in effect at the time, and the number of Common Stock and the amount, if any, of other securities
or property which at the time would be received upon the conversion of this Advance Note. Notwithstanding the foregoing, the Company shall
not be obligated to deliver a certificate unless such certificate would reflect an increase or decrease of at least one percent of such
adjusted amount.


 


(e) Issuance
Taxes. The Company shall pay any and all issuance and other taxes, excluding federal, state or local income taxes, that may be payable
in respect of any issue or delivery of Common Stock on conversion of this Advance Note pursuant thereto; provided, however,
that the Company shall not be obligated to pay any transfer taxes resulting from any transfer requested by the Holder in connection with
any such conversion.


 


(f) Reservation
of Common Stock. The Company shall at all times while this Advance Note shall be outstanding, reserve and keep available out of its
authorized but unissued Common Stock at least the Required Minimum of Common Stock (disregarding for this purpose any and all limitations
of any kind on such conversion). The Company shall, from time-to-time, increase the authorized number of Common Stock or take other effective
action if at any time the unissued number of authorized shares shall not be sufficient to satisfy the Company’s obligations under
this Section 3.3(f).


 






    A-14


     


    

 


(g) Regulatory
Compliance. If any Common Stock to be reserved for the purpose of conversion of this Advance Note requires registration or listing
with or approval of any governmental authority, national securities exchange or other regulatory body under any federal or state law or
regulation or otherwise before such shares may be validly issued or delivered upon conversion, the Company shall, at its sole cost and
expense, in good faith and as expeditiously as possible, secure such registration, listing or approval, as the case may be.


 


3.4 Rights
Upon Fundamental Transaction


 


(a) Assumption. 
The Company shall not enter into or be party to a Fundamental Transaction unless the Person (which may be the Company) formed by, resulting
from or surviving any Fundamental Transaction or the Person with which such Fundamental Transaction shall have been entered into (the
“Successor Entity”) assumes in writing all of the obligations of the Company under this Advance Note and the other
Transaction Documents in accordance with the provisions of this Section 3.4(a) pursuant to written agreements in form and substance reasonably
satisfactory to the Holder and approved by the Holder prior to such Fundamental Transaction, including agreements to deliver to each holder
of Advance Notes in exchange for such Advance Notes a security of the Successor Entity evidenced by a written instrument substantially
similar in form and substance to the Advance Notes, including, without limitation, having Principal and Interest equal to the Principal
then outstanding and any accrued and unpaid Interest thereon (if any) of the Advance Notes held by the Holder, having similar conversion
rights as the Advance Notes and having similar ranking and security to the Advance Notes on the Collateral. Upon the occurrence of any
Fundamental Transaction, the Successor Entity shall succeed to, and be substituted for (so that from and after the date of such Fundamental
Transaction, the provisions of this Advance Note 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 Advance Note and the other Transaction Documents with the same effect as if such Successor Entity had been named as
the Company herein.  Upon consummation of a Fundamental Transaction, the Successor Entity shall deliver to the Holder confirmation
that there shall be issued upon conversion or redemption of this Advance Note at any time after the consummation of such Fundamental Transaction,
in lieu of the shares of Common Stock issuable upon the conversion or redemption of this Advance Note prior to such Fundamental Transaction,
such shares of the common stock (or their equivalent), securities or other assets of the Successor Entity (including its parent entity)
which the Holder would have been entitled to receive upon the happening of such Fundamental Transaction had this Advance Note been converted
immediately prior to such Fundamental Transaction at the applicable Conversion Price in effect immediately prior to such Fundamental Transaction
(without regard to any limitations on the conversion of this Advance Note), as adjusted in accordance with the provisions of this Advance
Note. Notwithstanding the foregoing, the Holder may elect, at its sole option, by delivery of written notice to the Company to waive this
Section 3.4(a) to permit the Fundamental Transaction without the assumption of this Advance Note.  The provisions of this Section
3.4(a) shall apply similarly and equally to successive Fundamental Transactions and shall be applied without regard to any limitations
on the conversion of this Advance Note.


 


(b) Other
Corporate Events.  In addition to and not in substitution for any other rights hereunder (but without duplication of Section
3.4(a) or any adjustment pursuant to Section 3.3(a)(iv)), prior to the consummation of any 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 ensure that the Holder will thereafter have
the right to receive upon a conversion of this Advance Note, such securities or other assets to which the Holder would have been entitled
with respect to such shares of Common Stock issuable on conversion of this Advance Note, at the applicable Conversion Price in effect
immediately prior to such Corporate Event, had such shares of Common Stock been held by the Holder upon the consummation of such Corporate
Event (without taking into account any limitations or restrictions on the convertibility of this Advance Note). Provision made pursuant
to the preceding sentence shall be in a form and substance reasonably satisfactory to the Holder.  The provisions of this Section
3.4(b) shall apply similarly and equally to successive Corporate Events and shall be applied without regard to any limitations on the
conversion or redemption of this Advance Note or any other security beneficially owned by the Holder.


 






    A-15


     


    

 


(c) Prepayment
Following a Change of Control. No later than five Trading Days following the entry by the Company into an agreement for a Change of
Control but in no event prior to the public announcement of such Change of Control, the Company shall deliver written notice describing
the entry into such agreement (“Notice of Change of Control”) to the Holder. Within 30 days after receipt of a Notice
of Change of Control, the Holder may require the Company to prepay, effective immediately prior to the consummation of such Change of
Control, an amount equal to 105% of the sum of (x) the outstanding Principal of this Advance Note and (y) and any accrued and unpaid Interest
thereon (the “COC Repayment Price”), by delivering written notice thereof (“Notice of Prepayment at Option
of Holder Upon Change of Control”) to the Company.


 


(d) Payment of COC
Repayment Price. Upon the Company’s receipt of a Notice(s) of Prepayment at Option of Holder Upon Change of Control from
the Holder, the Company shall deliver the COC Repayment Price to the Holder immediately prior to the consummation of the Change of
Control; provided, that the Holder’s original of this Advance Note shall have been so delivered to the Company,
and, provided, further that all payments shall be subject to the provisions of the Purchase Agreement with respect to
the holders of the Other Advance Note and any Pre-Paid Tranches.


 


3.5 Inability
to Fully Convert.


 


(a) Holder’s
Option if Company Cannot Fully Convert. If, upon the Company’s receipt of a Notice of Conversion or as otherwise required under
this Advance Note, including with respect to repayment of Principal, the Company cannot issue all or any portion of the Common Stock due
on such conversion for any reason, including, without limitation, because the Company (x) does not have a sufficient number of shares
of Common Stock authorized and available or (y) is otherwise prohibited by applicable law or by the rules or regulations of any national
securities exchange, interdealer quotation system or other self-regulatory organization with jurisdiction over the Company or any of its
securities from issuing all of the shares of Common Stock which are to be issued to the Holder pursuant to this Advance Note, then the
Company shall issue as many shares of Common Stock as it is able to issue and, with respect to the unconverted portion of this Advance
Note or with respect to any Common Stock not timely issued in accordance with this Advance Note, the Holder, solely at Holder’s
option, can elect to:


 


(i) require
the Company to prepay that portion of this Advance Note for which the Company is unable to issue Common Stock or for which Common Stock
was not timely issued (the “Mandatory Prepayment”) at a price equal to the number of shares of Common Stock that the
Company is unable to issue multiplied by the VWAP on the date of the Notice of Conversion (provided all payments shall be subject to the
provisions of the Purchase Agreement with respect to the holders of the Other Advance Notes and any Pre-Paid Tranches); provided
that, notwithstanding anything in this Advance Note or the Purchase Agreement to the contrary, the payment of such amount shall cure any
breach or Event of Default arising from such failure to deliver shares of Common Stock on such conversion;


 


(ii) void
its Notice of Conversion and retain or have returned, as the case may be, this Advance Note or the portion of this Advance Note that was
to be converted pursuant to the Notice of Conversion (provided that the Holder’s voiding its Notice of Conversion shall not
affect the Company’s obligations to make any payments which have accrued prior to the date of such notice); or


 


(iii) defer
issuance of the applicable Conversion Shares until such time as the Company can legally issue such shares; provided that the Principal
and any accrued and unpaid Interest thereon underlying such Conversion Shares shall remain outstanding until the delivery of such Conversion
Shares; and provided, further, that if the Holder elects to defer the issuance of the Conversion Shares, it may exercise
its rights under either clause (i) or (ii) above at any time prior to the issuance of the Conversion Shares upon two Trading Days’
notice to the Company. 


 






    A-16


     


    

 


(b) Mechanics
of Fulfilling Holder’s Election. The Company shall immediately send to the Holder, upon receipt of a Notice of Conversion from
the Holder, which cannot be fully satisfied as described in Section 3.6(a) above, a notice of the Company’s inability to fully satisfy
the Notice of Conversion (the “Inability to Fully Convert Notice”). Such Inability to Fully Convert Notice shall indicate
(i) the reason why the Company is unable to fully satisfy the Holder’s Notice of Conversion; and (ii) the amount of this Advance
Note which cannot be converted. The Holder shall notify the Company of its election pursuant to Section 3.5(a) above by delivering written
notice to the Company (“Notice in Response to Inability to Convert”).


 


(c) Payment
of Mandatory Prepayment Price. If the Holder shall elect to have its Advance Note prepaid pursuant to Section 3.2(c) or 3.5(a)(i)
above, the Company shall pay the Mandatory Prepayment Price to the Holder within five Trading Days of the Company’s receipt of the
Holder’s request for payment of the Mandatory Prepayment Price on a Conversion Failure or Notice in Response to Inability to Convert;
provided that prior to the Company’s receipt of the Holder’s request for payment of the Mandatory Prepayment Price
on a Conversion Failure or Notice in Response to Inability to Convert, as applicable, the Company has not delivered a notice to the Holder
stating, to the satisfaction of the Holder, that the event or condition resulting in the Mandatory Prepayment has been cured and all Conversion
Shares issuable to the Holder can and will be delivered to the Holder in accordance with the terms of this Advance Note.


 


(d) Purchase
Rights. If at any time the Company grants, issues or sells any options, other convertible securities or rights to purchase stock,
warrants, securities or other property pro rata to all or substantially all of the record holders of Common Stock (the “Purchase
Rights”), then the Holder will be entitled to acquire, upon the terms applicable to such Purchase Rights, the aggregate Purchase
Rights which the Holder could have acquired if the Holder had held the number of shares of Common Stock acquirable upon complete conversion
of this Advance Note (without taking into account any limitations or restrictions on the convertibility of this Advance Note) immediately
prior to the date on which a record is taken for the grant, issuance or sale of such Purchase Rights, or, if no such record is taken,
the date as of which the record holders of shares of Common Stock are to be determined for the grant, issue or sale of such Purchase Rights
(provided, however, that to the extent that the Holder’s right to participate in any such Purchase Right would result
in the Holder 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 to the extent of any such excess) and such Purchase Right to such extent shall be held in abeyance
(and, if such Purchase Right has an expiration date, maturity date or other similar provision, such term shall be extended by such number
of days held in abeyance, if applicable) 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 (and, if such Purchase Right has an expiration date, maturity date or other similar provision, such term shall be extended
by such number of days held in abeyance, if applicable)) to the same extent as if there had been no such limitation).


 


(e) No
Rights as Shareholder. Nothing contained in this Advance Note shall be construed as conferring upon the Holder, prior to the conversion
of this Advance Note, the right to vote or to receive dividends or to consent or to receive notice as a shareholder of the Company in
respect of any meeting of shareholders for the election of directors of the Company or of any other matter, or any other rights as a shareholder
of the Company.

ARTICLE
4


 


4.1 Covenants.
For so long as any Principal of this Advance Note remains outstanding, unless holders of at least 66.0% (but including each of the
initial holders of Closing Advance Notes, as long as such holder, or any of its Affiliates holds any outstanding Closing Advance
Notes or Pre-Paid Tranches) of the aggregate outstanding Principal of the Advance Notes, the Other Advance Note and any outstanding
Prepaid-Tranches have otherwise given prior written consent:


 


(a) Rank.
All payments due under this Advance Note shall rank senior to all other Indebtedness of the Company and its Subsidiaries, except for the
Other Advance Note, outstanding Prepaid-Tranches, upon issuance, or as reflected in the Purchase Agreement and, to the extent applicable,
any Permitted Indebtedness.


 


(b) Incurrence
of Indebtedness. The Company shall not, and the Company shall cause each of its Subsidiaries to not, directly or indirectly, incur
or guarantee or assume any Indebtedness (other than (i) this Advance Note, the Other Advance Note and the Prepaid-Tranches upon issuance,
and (ii) Permitted Indebtedness).


 


(c) Existence
of Liens. The Company shall not, and the Company shall cause each of its Subsidiaries to not, directly or indirectly, allow or suffer
to exist Liens other than Permitted Liens.


 


(d) Restricted
Payments. Except as otherwise provided for in this Advance Note, the Other Advance Note or the other Transaction Documents, the Company
shall not, and the Company shall cause each of its Subsidiaries to not, directly or indirectly, prepay, defease, repurchase, repay or
make any payments in respect of, by the payment of cash or cash equivalents (in whole or in part, whether by way of open market purchases,
tender offers, private transactions or otherwise), all or any portion of any Indebtedness (other than the Advance Note, the Other Advance

Excluded Subsidiary, pursuant to a Subsidiary Guarantee in the form attached as an exhibit to the Purchase Agreement.


 


1.2   Interest.



 


(a)   Interest
shall accrue hereunder at a rate equal to 4.5% per annum (or, if less, the highest amount permitted by law) (such interest shall be referred
to as “Interest” and such rate, the “Interest Rate”) on the Principal hereof and shall be due and
payable quarterly in arrears, commencing on March 31, 2023, on each March 31, June 30, September 30 and December 31 during the term of
this Advance Note (each, an “Interest Payment Date”), up to and including the final Interest Payment Date, which shall
be the Maturity Date, for the period (each, an “Interest Period”) (i) initially, commencing on and including the Original
Issuance Date and ending on and including March 31, 2023 and (ii) thereafter, commencing on and including the date that is one day after
the immediately preceding Interest Payment Date and ending on and including the last day of the third succeeding calendar month thereafter
(or, with respect to the Interest Payment Date that is the Maturity Date, ending on and including the Maturity Date). In the event of
any conversion of all or any portion of the Principal into Common Stock in accordance with the terms hereof during any Interest Period,
(i) Interest shall accrue at the Interest Rate on the outstanding Principal to and including the date of conversion and (ii) from and
after any date of conversion, Interest shall accrue on the then outstanding Principal to and including the succeeding date of conversion
(and in each case, on the then outstanding Principal thereafter) or, if earlier, the applicable Interest Payment Date.


 






    B-1


     


    

 


(b)   Interest
due on each Interest Payment Date shall be payable by the Company, at the Company’s option, (i) in kind, through the issuance of
a PIK Advance Note to the Holder in an aggregate principal amount equal to the amount of Interest due on such Interest Payment Date, in
accordance with (A) if the Equity Conditions are satisfied as of such Interest Payment Date, clause (2) below and (B) if the Equity Conditions
are not satisfied as of such Interest Payment Date or the Company is otherwise unable to issue a Registered PIK Advance Note to the Holder,
clause (3) below, or (ii) in cash.


 


(1)   In
the event the Company shall determine to pay Interest due on any Interest Payment Date through the issuance to the Holder of a PIK Advance
Note, the Company shall notify the Holder (which notice may be via e-mail) at least five Business Days prior to the applicable Interest
Payment Date (a “PIK Election Notice”).


 


(2) Subject to
the satisfaction of the Equity Conditions at such time, the Company may issue PIK Advance Notes to the Holder on a registered basis
(a “Registered PIK Advance Note”) in an aggregate principal amount equal to the amount of Interest that will
become due on such Interest Payment Date, in satisfaction thereof, under this Advance Note and any Other Advance Note (as defined
below) [or Prepaid-Tranche] then held by the Holder with respect to which the Company has elected to pay interest in kind in
accordance with the terms thereof (which aggregate amount shall be rounded up to the nearest whole dollar) and the Underlying Shares
thereof, pursuant to which the Holder shall receive freely tradeable shares of Common Stock on any conversion, at the discretion of
the Holder, of such PIK Advance Note. Prior to the open of trading on the Interest Payment Date on which such Interest would become
due, the Company shall file a prospectus supplement to its Form S-3 with the Commission covering the issuance to the Holder (and any
other holder of Closing Advance Notes or Prepaid-Tranches with respect to which the Company has elected to, and is then entitled to,
pay interest through the issuance of Registered PIK Advance Notes) of such Registered PIK Advance Note. Each Registered PIK Advance
Note shall be in the form of and on the same terms and conditions as a Registered Advance Note, other than the aggregate principal
amount thereof; provided, that, (i) such PIK Advance Note shall not bear any interest and (ii) the maturity date of
such PIK Advance Note shall be the Maturity Date. Notwithstanding any PIK Election Notice delivered by the Company, if the Equity
Conditions are not satisfied on any Interest Payment Date, the Company shall not have the right to issue a Registered PIK Advance
Note to the Holder.


 


(3)
If the Company is unable to issue a Registered PIK Advance Note to the Holder in accordance with clause (2) above, the Company may issue
PIK Advance Notes to the Holder on a private placement basis, pursuant to Section 4(a)(2) of the Securities Act, and Rule 506(b) promulgated
thereunder (a “Private Placement PIK Advance Note”) in an aggregate principal amount equal to the amount of Interest
that will become due on such Interest Payment Date, in satisfaction thereof, under this Advance Note and any Other Advance Note [or Prepaid-Tranche]
then held by the Holder with respect to which the Company has elected to pay interest in kind in accordance with the terms thereof (which
aggregate amount shall be rounded up to the nearest whole dollar). Each Private Placement PIK Advance Note shall be in the form of and
on the same terms and conditions as a Private Placement Advance Note, other than the aggregate principal amount thereof; provided,
that, (i) the outstanding principal amount of such Private Placement PIK Advance Note shall bear Interest at the Interest Rate,
which amount shall be payable in kind and capitalized to the outstanding principal amount of the Private Placement PIK Advance Note on
each Interest Payment Date, which principal amount (including any such capitalized interest) shall be payable in cash at the maturity
date of such Private Placement PIK Advance Note, (ii) the outstanding principal amount of such Private Placement PIK Advance Note (including
any such capitalized interest) shall be convertible into Common Stock in accordance with the terms of the Private Placement Advance Note
and (ii) the maturity date of such Private Placement PIK Advance Note shall be the Maturity Date.


 






    B-2


     


    

 


(4)   Any
PIK Advance Notes issued to the Holder hereunder will be considered to be part of the same series of, and rank equally and ratably with,
this Advance Note.


 


(c)   From
and after the occurrence and during the continuance of any Event of Default, interest shall accrue hereunder at a rate equal to 12% per
annum (or, if less, the highest amount permitted by law) (such interest upon an Event of Default shall be referred to as “Default
Interest”) and shall be due and payable in cash on the first Trading Day of each calendar month during the continuance of such
Event of Default (a “Default Interest Payment Date”). In the event that such Event of Default is subsequently cured
(and no other Event of Default then exists (including, without limitation, for the Company’s failure to pay such Default Interest
on the applicable Default Interest Payment Date)), the Default Interest shall cease to accrue hereunder as of the day immediately following
the date of such cure; provided that the Interest as calculated and unpaid at such increased rate during the continuance of such
Event of Default shall continue to apply to the extent relating to the days after the occurrence of such Event of Default through and
including the date of such cure of such Event of Default. Interest and Default Interest shall accrue based on a 360-day year composed
of twelve 30-day months and, for partial months, on the basis of the number of days actually elapsed in a 30-day month.


 


1.3 Prepayment. If
following the Original Issuance Date while this Advance Note is outstanding the Company directly or indirectly receives proceeds from
and closes any Subsequent Financing (other than any Permitted Private Placement Financing or Exempt Issuance), the Company shall give
written notice to the Holder within two Trading Days, and the Holder within five Trading Days after receipt of such written notice may
request a prepayment of Principal and any accrued and unpaid Interest thereon (if any) in an amount up to the Holder’s pro rata
portion (based on the ratio of (a) the Principal of this Advance Note for such Purchaser to (b) the sum of the aggregate Principal of
all Advance Notes made to the Purchasers under the Purchase Agreement) of 30% of the gross proceeds received by the Company from such
Subsequent Financing. Except as otherwise provided elsewhere in the Purchase Agreement or this Advance Note, the Company may not prepay
any portion of the Principal.


 


1.4   Payment
on Non-Trading Days. Whenever any payment to be made on this Advance Note shall be due on a day which is not a Trading Day, such payment
may be due on the next succeeding Trading Day.


 


1.5   Replacement.
Upon receipt of a duly executed Affidavit of Loss and Indemnity Agreement in customary form from the Holder with respect to the loss,
theft or destruction of this Advance Note (or any replacement hereof), or, in the case of a mutilation of this Advance Note, upon surrender
and cancellation of such Advance Note, the Company shall issue a new Advance Note, of like tenor and amount, in lieu of such lost, stolen,
destroyed or mutilated Advance Note.


 


1.6   Status
of Advance Note. The obligations of the Company under this Advance Note shall rank senior to all other existing Indebtedness and equity
of the Company, other than the amounts owing to the holders under the other Closing Advance Notes (each, an “Other Advance Note”)
and the Prepaid-Tranches, when issued, to the extent of the first lien security interest in the collateral per the Security Agreement,
and, to the extent applicable, any Permitted Indebtedness or other Indebtedness secured by Permitted Liens. The obligations of the Company
under this Advance Note shall rank pari passu with the amounts owing to the other Purchasers under the Other Advance Notes and
with the amounts owing under any then-outstanding Prepaid-Tranches. Upon any Liquidation Event (as hereinafter defined), but subject in
all cases to the Purchase Agreement, the Holder will be entitled to receive, before any distribution or payment is made upon, or set apart
with respect to, any Indebtedness of the Company (other than the Other Advance Notes) or any class of capital stock of the Company, an
amount equal to the outstanding Principal, Interest and any other sums due hereunder. For purposes of this Advance Note, “Liquidation
Event” means a liquidation pursuant to a filing of a petition for bankruptcy under applicable law or any other insolvency or
debtor’s relief, an assignment for the benefit of creditors, or a voluntary or involuntary liquidation, dissolution or winding up
of the affairs of the Company.

2.2   Remedies
Upon an Event of Default.


 


(a)   Upon
the occurrence of any Event of Default that has not been remedied or waived within three Trading Days or, with respect to the Event of
Default described in Section 2.1(h), two Trading Days (provided, however, that there shall be no cure period for an Event
of Default described in Section 2.1(j), 2.1(k) or 2.1(l)), the Company shall be obligated to pay to the Holder the Mandatory Default Amount,
which Mandatory Default Amount shall be immediately due and payable to the Holder, anything contained in any Transaction Document to the
contrary notwithstanding. In the event this Advance Note shall be converted under an Event of Default, prior to (and in place of) any
payment of the Mandatory Default Amount to the Holder, the Holder shall have the option to convert the aggregate outstanding Principal
of this Advance Note at the Alternative Conversion Price (provided that all payments shall be subject to the provisions of the Purchase
Agreement with respect to the holders of the Other Advance Notes). For this purpose, the Holder shall have the option to have the Alternative
Conversion Price determined as of the date the Notice of Conversion for such conversion is delivered by the Holder to the Company, rather
than the date of such Event of Default.


 


(b)   Upon
the occurrence of any Event of Default, the Company shall, as promptly as possible but in any event within two Trading Days of the occurrence
of such Event of Default, notify the Holder of the occurrence of such Event of Default, describing the event or factual situation giving
rise to the Event of Default and specifying the relevant subsection or subsections of Section 2.1 hereof under which such Event of Default
has occurred.


 


(c)   The
provisions of Section 3.2(b) and (c) shall also apply upon any Events of Default relating to Conversion Shares in addition to the remedies
under this Section 2.2.


 


(d)   Any
Event of Default hereunder may be waived upon the mutual agreement of the Parties.

3.1   Conversion.


 


(a)   Conversion.
At any time after the Original Issuance Date, this Advance Note shall be convertible (in whole or in part) at the option of the Holder
into such number of fully paid and non-assessable shares of Common Stock as is determined by dividing (x) that portion of the outstanding
Principal and any accrued and unpaid Interest thereon that the Holder elects to convert (the “Conversion Amount”) by
(y) the Conversion Price (as hereinafter defined) then in effect on the date on which the Holder delivers to the Company a notice of conversion
in substantially the form attached hereto as Exhibit A (the “Notice of Conversion”) in accordance with Section
5.1. The Holder shall deliver this Advance Note to the Company at the address designated in the Purchase Agreement at such time that this
Advance Note is fully converted. With respect to partial conversions of this Advance Note, the Company shall keep written records of the
amount of this Advance Note converted as of the date of such conversion (each, a “Conversion Date”).


 






    B-7


     


    

 


(b)   Conversion
Price.


 


(i)   The
“Conversion Price” means the lesser of (i) the average of the preceding five daily VWAPs calculated using the last
Trading Day prior to the Initial Closing [or, in the case of any Pre-Paid Tranche, any Monthly Closing, as the case may be,] times 130%
(the “Fixed Conversion Price”), which Fixed Conversion Price shall be subject to adjustment as provided herein, or
(ii) 92.5% of the average of the three lowest daily VWAPs during the prior 10 Trading Days ending on the last Trading Day prior to the
delivery of a Notice of Conversion by the Holder (or the same Trading Day, if the Notice of Conversion is delivered after the close of
trading on the Principal Market on such date) (the “Variable Conversion Price”).


 


(ii)   At
any time the Company receives a Note of Conversion at a time that the Conversion Price (or, as applicable, the Alternative Conversion
Price) then in effect, without regard to the Floor Price (the “Applicable Conversion Price”), is less than the Floor
Price then in effect (unless such Floor Price is lowered with the written consent of the Company and the Holder of this Advance Note,
which may be an e-mail), the Company shall issue a number of shares equal to the Conversion Amount divided by such Floor Price and pay
the economic difference between the Applicable Conversion Price and such Floor Price in cash. For further clarification, the economic
difference shall be equal to (A) the number of shares that would have been delivered using the Applicable Conversion Price, minus (B)
the number of shares delivered using the Floor Price multiplied by (C) the daily VWAP of the Common Stock on the Conversion Date ((A-B)*C).
The failure to pay any cash due in connection with a conversion shall be deemed an Event of Default, subject to Section 2.2(a). 


 


(c)   Voluntary
Adjustment of Fixed Conversion Price. Subject to the rules and regulations of the Principal Market, the Company may at any time during
the term of this Advance Note, with the prior written consent of the Required Holders, reduce the then current Fixed Conversion Price
of each of the Advance Notes to any amount and for any period of time deemed appropriate by the board of directors of the Company.


 


3.2   Delivery
of Conversion Shares. 


 


(a)   As
soon as practicable after any conversion or payment of any amount due hereunder in the form of shares of Common Stock in accordance with
this Advance Note, and in any event within the earlier of (i) two (2) Trading Days following the delivery of the Notice of Conversion
and (ii) the expiration of the Standard Settlement Period thereafter (such date, the “Share Delivery Date”), the Company
shall, at its expense, cause to be issued in the name of and delivered to the Holder, or as the Holder may direct, the number of shares
of fully paid and non-assessable Common Stock to which the Holder shall be entitled on such conversion or payment (the “Conversion
Shares”), which Conversion Shares shall be free of restrictive and trading legends and delivered electronically to the Holder
(or its designee), by crediting the account of the Holder’s (or such designee’s) broker with DTC through its Deposit Withdrawal
At Custodian system as instructed by the Holder (or its designee).


 


(b)   Obligation
Absolute. The Company’s obligations to issue and deliver the Conversion Shares upon conversion of this Advance Note in accordance
with the terms hereof are absolute and unconditional, irrespective of any action or inaction by the Holder to enforce the same, any waiver
or consent with respect to any provision hereof (other than any express written waiver by the Holder entitled to receive such Conversion
Shares of the obligation to issue and deliver the same), the recovery of any judgment against any Person or any action to enforce the
same, or any setoff, counterclaim, recoupment, limitation or termination, or any breach or alleged breach by the Holder or any other Person
of any obligation to the Company or any violation or alleged violation of law by the Holder or any other Person, and irrespective of any
other circumstance which might otherwise limit such obligation of the Company to the Holder in connection with the issuance of such Conversion
Shares (other than any such limitation expressly set forth in the Transaction Documents); provided, however, that such delivery
shall not operate as a waiver by the Company of any such action the Company may have against the Holder. In the event the Holder of this
Advance Note shall elect to convert any or all of the outstanding Principal and any accrued and unpaid Interest thereon hereof, the Company
may not refuse conversion based on any claim that the Holder or anyone associated or affiliated with the Holder has been engaged in any
violation of law, agreement or for any other reason, unless an injunction from a court, on notice to Holder, restraining and or enjoining
conversion of all or part of this Advance Note shall have been sought and obtained, and the Company posts a surety bond for the benefit
of the Holder in the amount of 100% of the outstanding Principal of this Advance Note and any accrued and unpaid Interest thereon, which
is subject to the injunction, which bond shall remain in effect until the completion of litigation of the underlying dispute and the proceeds
of which shall be payable to the Holder to the extent it obtains a favorable judgment, with any amount of the surety bond in excess of
any such money judgment to be applied as a repayment of such outstanding Principal and accrued and unpaid interest thereon and other amounts
then payable by the Company to the Holder under this Advance Note. In the absence of such injunction, the Company shall issue the Conversion
Shares or, if applicable, cash, upon delivery of a Notice of Conversion on the terms set forth in this Advance Note.


 






    B-8


     


    

 


(c) The Company’s Failure
to Timely Convert. If the Company shall fail for any reason or for no reason, on or prior to the applicable Share Delivery Date,
to credit the balance account of the Holder or the Holder’s designee with DTC for such number of Conversion Shares to which the
Holder is entitled upon the Holder’s conversion of this Advance Note, as the case may be (in each case, other than to the extent
such failure arose from any action taken or not taken by the Holder or its designee with DTC) (a “Conversion Failure”),
then, in addition to all other remedies available to the Holder, the Holder may by notice to the Company (in lieu of receiving such Conversion
Shares subject to such Conversion Failure), require the Company to either, at the Holder’s option, (1) redeem, in cash, the Conversion
Amount in such Conversion Failure at a redemption price equal to the product of (i) the number of shares of Common Stock subject to such
Conversion Failure multiplied by (ii) the VWAP on the date of the Notice of Conversion (the “Mandatory Prepayment Price”);
provided that, notwithstanding anything in this Advance Note or the Purchase Agreement to the contrary, the payment of the Mandatory
Prepayment Price shall cure any breach or Event of Default arising from such Conversion Failure, or (2) pay to the Holder in cash, as
liquidated damages and not as a penalty, for each $1,000 of Principal being converted, $5 per Trading Day (increasing to $10 per Trading
Day on the fifth (5th) Trading Day after such liquidated damages begin to accrue) for each Trading Day after such Share Delivery
Date until such Conversion Shares are delivered or Holder rescinds such conversion. In addition to the foregoing, if on or prior to the
Share Delivery Date, if 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 conversion hereunder (in each case,
other than to the extent such failure arose from any action taken or not taken by the Holder or its designee with DTC), and if on or
after such Share Delivery Date the Holder acquires (in an open market transaction or otherwise) shares of Common Stock to deliver in
satisfaction of a sale by the Holder of all or any portion of the number of shares of Common Stock issuable upon such conversion that
the Holder is entitled to receive from the Company and has not received from the Company in connection with such Conversion Failure (a
“Buy-In”), the “Buy-In” provisions of Section 4.1(d) of the Purchase Agreement shall apply in accordance
with the terms thereof. 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 conversion of this Advance Note as required pursuant to the terms hereof.


 


(d) Pro Rata
Conversion; Disputes. In the event that the Company receives a Notice of Conversion from the Holder, the holders of the Other
Advance Notes or of any Prepaid-Tranches or Warrant and/or any holders of options, or other convertible securities for the same
Conversion Date and the Company can convert some, but not all, of such portions of the Closing Advance Notes, Prepaid-Tranches,
Warrants, options or other convertible securities submitted for conversion, the Company, subject to this Section 3.2(d), shall (i)
first convert the entire Conversion Amount submitted for conversion on such date by the Holder and the holders of the Other Advance
Notes and of any Prepaid-Tranches, if any, or Warrants on a pro rata basis, and (ii) shall thereafter convert from each holder of
options or other convertible securities electing to have options, warrants or other convertible securities converted on such date
(other than the Closing Advance Notes, Prepaid-Tranches or Warrants) a pro rata amount of such holder’s portion of its options
or other convertible securities submitted for conversion based on the aggregate number of shares of Common Stock issuable upon
exercise (or conversion) of all options or other convertible securities submitted for conversion on such date (not including the
Closing Advance Notes and Prepaid-Tranches).


 






    B-9


     


    

 


(e)   Beneficial
Ownership Limitation. The Company shall not effect the conversion of any portion of this Advance Note [or any Prepaid-Tranche] (or
the exercise of any Warrants), and the Holder shall not have the right to convert any portion of this Advance Note or any Other Advance
Note [or any Prepaid-Tranche] pursuant to the terms and conditions of this Advance Note or any Other Advance Note [or any Prepaid-Tranche]
(or the exercise of any Warrants) and any such conversion shall be null and void and treated as if never made, to the extent that after
giving effect to such conversion or 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 conversion. 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 conversion of this Advance Note or any Other Advance Note [or any Prepaid-Tranche]
(or the exercise of any Warrants) 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) conversion of the remaining, non-converted portion of this Advance Note or any Other Advance
Note [or any Prepaid-Tranche] (or the exercise of any Warrants) beneficially owned by the Holder or any of the other Attribution Parties
and (B) exercise or conversion of the unexercised or non-converted portion of any other securities of the Company (including, without
limitation, any convertible notes or convertible preferred stock or warrants, including, without limitation, the 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 3.2(e). For purposes of this Section 3.2(e), beneficial ownership shall be calculated in accordance with Section 13(d)
of the Exchange Act. For purposes of determining the number of outstanding shares of Common Stock the Holder may acquire upon the
conversion of this Advance Note [or any Prepaid-Tranche] (or exercise of any Warrants) 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 a Notice
of Conversion 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 notify the Holder in writing of the number of shares of Common Stock then outstanding and, to the extent
that such Notice of Conversion would otherwise cause the Holder’s beneficial ownership, as determined pursuant to this Section 3.2(e),
to exceed the Maximum Percentage, the Holder must notify the Company of a reduced number of shares of Common Stock to be purchased pursuant
to such Notice of Conversion. For any reason at any time, upon the written or oral request of the Holder, the Company shall within
one Trading 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 Advance Note or any Other Advance Note [or any Prepaid-Tranche] (or the exercise of any Warrants),
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 conversion of this Advance Note or any Other Advance Note [or
any Prepaid-Tranche] (or the exercise of any Warrants) 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 Exchange 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. To the extent that the limitation
contained in this Section 3.2(e) applies, the determination of whether and what portion of this Advance Note may be converted into shares
of Common Stock (in relation to other securities owned by the Holder together with any Affiliates and Attribution Parties) and of which
portion of this Advance Note is convertible at any given time shall be in the sole discretion of the Holder, and the submission of a Notice
of Conversion shall be deemed to be the Holder’s determination of whether and for what amount of shares of Common Stock this Advance
Note is convertible at such time (in relation to other securities owned by the Holder together with any Affiliates and Attribution Parties),
in each case subject to the Beneficial Ownership Limitation, and the Company shall have no obligation to verify or confirm the accuracy
of such determination. Provided, however, the Company shall indemnify the Holder in accordance with the Purchase Agreement
for any damages the Holder may sustain as the result of Excess Shares being issued due to an error of the Transfer Agent or any replacement
transfer agent. Upon delivery of a written notice to the Company, the Holder may from time to time increase (with such increase not effective
until the 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 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 an Advance Note 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 Advance Note or any Other Advance Note [or any Prepaid-Tranche] (or
the exercise of any Warrants) 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 Exchange Act. No prior inability to convert this Advance Note
pursuant to this Section 3.2(e) shall have any effect on the applicability of the provisions of this Section 3.2(e) with respect to any
subsequent determination of convertibility. The provisions of this paragraph shall not be construed and implemented in a manner
otherwise than in strict conformity with the terms of this Section 3.2(e) to the extent necessary to correct any provision hereof which
may be defective or inconsistent with the intended beneficial ownership limitation contained in this Section 3.2(e) or to make changes
or supplements necessary or desirable to properly give effect to such limitation. The limitation contained in this Section 3.2(e)
may not be waived and shall apply to a successor holder of this Advance Note.

3.3 Adjustment
of Fixed Conversion Price. 


 


(a) Until
this Advance Note has been paid in full or converted in full, the Fixed Conversion Price shall be subject to adjustment from time-to-time
as follows (but shall not be increased, other than pursuant to a combination):


 


(i) Adjustments
for Stock Splits and Combinations. If the Company shall at any time or from time-to-time after the Original Issuance Date effect a
split of the outstanding Common Stock or pay a dividend in Common Stock to holders of its Common Stock, the applicable Fixed Conversion
Price in effect immediately prior to the stock split shall be proportionately decreased. If the Company shall at any time or from time-to-time
after the Original Issuance Date, combine the outstanding Common Stock into a lesser number of shares, the applicable Fixed Conversion
Price in effect immediately prior to the combination shall be proportionately increased. Any adjustments under this Section 3.3(a)(i)
shall be effective at the close of business on the date the stock split, stock dividend, or combination occurs. 


 


(ii) Adjustments
for Certain Dividends and Distributions. If the Company shall at any time or from time-to-time after the Original Issuance Date make
or issue or set a record date for the determination of holders of Common Stock entitled to receive a dividend or other distribution payable
in Common Stock, then, and in each event, the applicable Fixed Conversion Price in effect immediately prior to such event shall be decreased
as of the time of such issuance or, in the event such record date shall have been fixed, as of the close of business on such record date,
by multiplying the applicable Fixed Conversion Price then in effect by a fraction:


 


(1) the
numerator of which shall be the total number of shares of Common Stock issued and outstanding immediately prior to the time of such issuance
or the close of business on such record date; and


 


(2) the
denominator of which shall be the total number of shares of Common Stock issued and outstanding immediately prior to the time of such
issuance or the close of business on such record date plus the number of Common Stock issuable in payment of such dividend or distribution;


 


provided, however,
that, if the Company shall at any time set a record date for the determination of holders of Common Stock entitled to receive a dividend
or other distribution payable in Common Stock and (A) such dividend is not fully paid or if such distribution is not fully made on the
date fixed therefor, the Fixed Conversion Price shall be adjusted pursuant to this Section 3.3(a)(ii) as of the time of actual payment
of such dividends or distributions or (B) the Company shall subsequently rescind or otherwise cancel or determine not to make such dividend
or distribution, then any adjustment to the Fixed Conversion Price made pursuant to this clause (ii) with respect to the fixing of such
record date shall be reversed and of no further force or effect as of the date of the Company’s public announcement that it is rescinding
or otherwise canceling or determining not making such dividend or distribution.


 


(iii) Adjustment
for Other Dividends and Distributions. If the Company shall at any time or from time-to-time after the Original Issuance Date make
or issue a dividend or other distribution payable in other Common Stock, securities of the Company, securities of another entity or other
assets, then, and in each event, the Holder of this Advance Note shall receive upon conversions hereof, in addition to the number of shares
of Common Stock receivable thereon, the number of securities of the Company or other issuer (as applicable) or other property that it
would have received had this Advance Note been converted into Common Stock in full (without regard to any conversion limitations herein)
on the date of such event and had thereafter, during the period from the date of such event to and including the Conversion Date, retained
such securities (together with any distributions payable thereon during such period) or assets, giving application to all adjustments
called for during such period under this Section 3.3(a)(iii) with respect to the rights of the holders of this Advance Note.


 






    B-11


     


    

 


(iv) Adjustments
for Reclassification, Exchange or Substitution. If the Common Stock at any time or from time to time after the Original Issuance Date
shall be changed to the same or different number of shares or other securities of any class or classes of stock or other property, whether
by reclassification, exchange, substitution or otherwise (other than by way of a stock split or combination of shares or stock dividends
or other distributions provided for in Sections 3.3(a)(i), (ii) and (iii) hereof), then, and in each event, an appropriate revision to
the Fixed Conversion Price shall be made and provisions shall be made (by adjustments of the Fixed Conversion Price or otherwise) so that
the Holder shall have the right thereafter to convert this Advance Note into the kind and amount of shares of stock or other securities
or other property receivable upon reclassification, exchange, substitution or other change, by holders of the number of shares of Common
Stock into which such Advance Note might have been converted immediately prior to such reclassification, exchange, substitution or other
change, all subject to further adjustment as provided herein.


 


(v) Rights
Upon Issuance of Other Securities.


 


(1) Adjustment
of Fixed Conversion Price upon Issuance of Common Stock. If and whenever on or after the Original Issuance Date the Company issues
or sells, or in accordance with this Section 3.3(a) is deemed to have issued or sold, any shares of Common Stock (including the issuance
or sale of shares of Common Stock owned or held by or for the account of the Company, but excluding any Exempt Issuance (other than clause
(d) of the definition of Exempt Issuance in the Purchase Agreement which shall not be deemed to be an Exempt Issuance for purposes of
this Section 3.3(a)(v) issued or sold or deemed to have been issued or sold) for a consideration per share (the “Dilutive Issuance
Price”) less than a price equal to the Fixed Conversion Price in effect immediately prior to such issuance or sale or deemed
issuance or sale (such Fixed Conversion Price then in effect is referred to herein as the “Applicable Price”) (the foregoing
a “Dilutive Issuance”), then, immediately after such Dilutive Issuance, the Fixed Conversion Price then in effect shall
be reduced to the lower of (i) an amount equal to the Dilutive Issuance Price, or (ii) the VWAP on the Trading Day following the first
public disclosure of the Dilutive Issuance (other than clause (d) of the definition of Exempt Issuance in the Purchase Agreement which
shall not be deemed to be an Exempt Issuance for purposes of this Section 3.3(a)(v)). For the purposes of this Section 3.3(a)(v), the
next Trading Day if an announcement is made before 4:00 pm New York, N.Y. time is either the day of the announcement or the following
Trading Day. For all purposes of the foregoing (including, without limitation, determining the adjusted Fixed Conversion Price and the
Dilutive Issuance Price under this Section 3.3(a)(v)), the following shall be applicable:


 


(2) Issuance
of Options. If the Company in any manner grants or sells any options or rights to acquire Common Stock or Convertible Securities (“Options”)
(other than pursuant to any Exempt Issuance) and the lowest price per share for which one share of Common Stock is at any time issuable
upon the exercise of any such Option or upon conversion, exercise or exchange of any Convertible Securities issuable upon exercise of
any such Option or otherwise pursuant to the terms thereof is less than the Applicable Price, then such share of Common Stock shall be
deemed to be outstanding and to have been issued and sold by the Company at the time of the granting or sale of such Option for such price
per share, excluding any transactions involving an Exempt Issuance. For purposes of this Section 3.3(a)(v) the “lowest price per
share for which one share of Common Stock is at any time issuable upon the exercise of any such Option or upon conversion, exercise or
exchange of any Convertible Securities issuable upon exercise of any such Option or otherwise pursuant to the terms thereof” shall
be equal to (1) the lower of (x) the sum of the lowest amounts of consideration (if any) received or receivable by the Company with respect
to any one share of Common Stock upon the granting or sale of such Option, upon exercise of such Option and upon conversion, exercise
or exchange of any Convertible Security issuable upon exercise of such Option or otherwise pursuant to the terms thereof and (y) the lowest
exercise price set forth in such Option for which one share of Common Stock is issuable (or may become issuable assuming all possible
market conditions) upon the exercise of any such Options or upon conversion, exercise or exchange of any Convertible Securities issuable
upon exercise of any such Option or otherwise pursuant to the terms thereof, minus (2) (x) the sum of all amounts paid or payable to the
holder of such Option (or any other Person) upon the granting or sale of such Option, upon exercise of such Option and upon conversion,
exercise or exchange of any Convertible Security issuable upon exercise of such Option or otherwise pursuant to the terms thereof plus
the value of any other consideration received or receivable by, or benefit conferred on, the holder of such Option (or any other Person)
divided by (y) the number of shares of Common Stock issuable upon exercise of such Option or upon conversion, exercise or exchange of
any Convertible Security issuable upon exercise of such Option. Except as contemplated below, no further adjustment of the Fixed Conversion
Price shall be made upon the actual issuance of such share of Common Stock or of such Convertible Securities upon the exercise of such
Options or otherwise pursuant to the terms thereof or upon the actual issuance of such shares of Common Stock upon conversion, exercise
or exchange of such Convertible Securities.


 






    B-12


     


    

 


(3) Issuance
of Convertible Securities. If the Company in any manner issues or sells any Convertible Securities and the lowest price per share
for which one share of Common Stock is at any time issuable upon the conversion, exercise or exchange thereof or otherwise pursuant to
the terms thereof is less than the Applicable Price, then such share of Common Stock shall be deemed to be outstanding and to have been
issued and sold by the Company at the time of the issuance or sale of such Convertible Securities for such price per share. For the purposes
of this Section 3.3(a)(v), the “lowest price per share for which one share of Common Stock is at any time issuable upon the conversion,
exercise or exchange thereof or otherwise pursuant to the terms thereof” shall be equal to (A) the lower of (x) the sum of the lowest
amounts of consideration (if any) received or receivable by the Company with respect to one share of Common Stock upon the issuance or
sale of the Convertible Security and upon conversion, exercise or exchange of such Convertible Security or otherwise pursuant to the terms
thereof and (y) the lowest Conversion Price set forth in such Convertible Security for which one share of Common Stock is issuable (or
may become issuable assuming all possible market conditions) upon conversion, exercise or exchange thereof or otherwise pursuant to the
terms thereof minus (B) (x) the sum of all amounts paid or payable to the holder of such Convertible Security (or any other Person) upon
the issuance or sale of such Convertible Security plus the value of any other consideration received or receivable by, or benefit conferred
on, the holder of such Convertible Security (or any other Person) divided by (y) the number of shares of Common Stock issuable upon conversion,
exercise or exchange of such Convertible Security. Except as contemplated below, no further adjustment of the Fixed Conversion Price shall
be made upon the actual issuance of such shares of Common Stock upon conversion, exercise or exchange of such Convertible Securities or
otherwise pursuant to the terms thereof, and if any such issuance or sale of such Convertible Securities is made upon exercise of any
Options for which adjustment of the Fixed Conversion Price has been or is to be made pursuant to other provisions of this Section 3.3(a)(v),
except as contemplated below, no further adjustment of the Fixed Conversion Price shall be made by reason of such issuance or sale.


 


(4) Change
in Option Price or Rate of Conversion. If the purchase or exercise price provided for in any Options, the additional consideration,
if any, payable upon the issue, conversion, exercise or exchange of any Convertible Securities, or the rate at which any Convertible Securities
are convertible into or exercisable or exchangeable for shares of Common Stock decreases at any time (other than proportional changes
in connection with an event referred to Section 3.3(a)(i) above), the Fixed Conversion Price in effect at the time of such decrease shall
be adjusted to the Fixed Conversion Price which would have been in effect at such time had such Options or Convertible Securities provided
for such decreased purchase price, additional consideration or decreased conversion rate (as the case may be) at the time initially granted,
issued or sold. For purposes of this Section 3.3(a)(v), if the terms of any Option or Convertible Security that was outstanding as of
the Issuance Date are decreased in the manner described in the immediately preceding sentence, then such Option or Convertible Security
and the shares of Common Stock deemed issuable upon exercise, conversion or exchange thereof shall be deemed to have been issued as of
the date of such decrease. No adjustment pursuant to this Section 3.3(a)(v) shall be made if such adjustment would result in an increase
of the Fixed Conversion Price then in effect.


 


(5) Issuances
of Units. In case any Options or Convertible Securities are issued in connection with the issue or sale of other securities of the
Company, together comprising one integrated transaction, at a price per unit that is less than the Applicable Price, then the shares of
Common Stock issuable upon the exercise of any such Option or upon conversion, exercise or exchange of any Convertible Securities issued
or sold in such integrated transaction shall be deemed to have been issued or sold by the Company at the time of the issuance or sale
of such Convertible Securities for such price per unit and, immediately after such issuance, the Fixed Conversion Price then in effect
shall be reduced to the lower of (i) an amount equal to the price per unit issuable in such transaction, or (ii) the lowest VWAP of the
Common Stock over the five Trading Days following the first public disclosure of such transaction. Any indebtedness shall be valued at
the principal less any original issue discount. If multiple shares of Common Stock are contained in a unit, the aggregate consideration
shall be divided by the number of shares of Common Stock in a unit. If any shares of Common Stock or Options or Convertible Securities
are issued or sold or deemed to have been issued or sold for cash, the amount of such consideration received by the Company will be deemed
to be the net amount received by the Company therefor. If any shares of Common Stock or Options or Convertible Securities are issued or
sold for a consideration other than cash, the amount of such consideration received by the Company will be the fair value of such consideration,
except where such consideration consists of publicly traded securities, in which case the amount of consideration received by the Company
will be the VWAP of such public traded securities on the date of receipt. If any shares of Common Stock or Options or Convertible Securities
are issued to the owners of the non-surviving entity in connection with any merger in which the Company is the surviving entity, the amount
of consideration therefor will be deemed to be the fair value of such portion of the net assets and business of the non-surviving entity
as is attributable to such shares of Common Stock or Options or Convertible Securities, as the case may be. No further adjustment of the
Fixed Conversion Price shall be made upon the actual issuance of such shares of Common Stock or of such Convertible Securities upon the
exercise of such Options or Convertible Securities or otherwise pursuant to the terms thereof.


 






    B-13


     


    

 


(6) Record
Date. If the Company takes a record of the holders of shares of Common Stock for the purpose of entitling them (A) to receive a dividend
or other distribution payable in shares of Common Stock, Options or in Convertible Securities or (B) to subscribe for or purchase shares
of Common Stock, Options or Convertible Securities, then such record date will be deemed to be the date of the issuance or sale of the
shares of Common Stock deemed to have been issued or sold upon the declaration of such dividend or the making of such other distribution
or the date of the granting of such right of subscription or purchase (as the case may be); provided, however, that, if
the Company shall at any time set a record date for the determination of holders of Common Stock entitled to receive a dividend or other
distribution payable in shares of Common Stock, Options or in Convertible Securities or to subscribe for or purchase shares of Common
Stock, Options or in Convertible Securities and (A) such dividend is not fully paid or if such distribution is not fully made, or the
subscription rights are not fully granted, on the date fixed therefor, the Fixed Conversion Price shall be adjusted pursuant to this Section
3.3(a)(v) as of the time of actual payment of such dividends or distributions or the effectiveness of such subscription rights or (B)
the Company shall subsequently rescind or otherwise cancel or determine not to make such dividend or distribution or to grant such subscription
rights, then any adjustment to the Fixed Conversion Price made pursuant to this Section 3.3(a)(v) with respect to the fixing of such record
date shall be reversed and of no further force or effect as of the date of the Company’s public announcement that it is rescinding
or otherwise canceling or determining not making such dividend or distribution or the grant of such subscription rights.


 


(b) Fractional
Shares. The Company shall not issue any fraction of a share of Common Stock upon any conversion. If the issuance would result in the
issuance of a fraction of a share of Common Stock, the Company shall round such fraction of a share of Common Stock to the nearest whole
share. If any adjustments to the Fixed Conversion Price under this Section 3.3 result in a fractional amount, the fractional amount rounded
to the nearest whole cent.


 


(c) No
Impairment. The Company shall not, by amendment of its Articles or Certificate of Incorporation or through any reorganization, transfer
of assets, consolidation, merger, dissolution, issue or sale of securities or any other voluntary action, avoid or seek to avoid the observance
or performance of any of the terms to be observed or performed hereunder by the Company, but will at all times in good faith assist in
the carrying out of all the provisions of this Section 3.3 and in the taking of all such action as may be necessary or appropriate in
order to protect the conversion rights of the Holder against impairment.


 


(d) Certificates
as to Adjustments. Upon occurrence of each adjustment or readjustment of the Fixed Conversion Price or number of shares of Common
Stock issuable upon conversion of this Advance Note pursuant to this Section 3.3, the Company at its expense shall promptly compute such
adjustment or readjustment in accordance with the terms hereof and furnish to the Holder a certificate setting forth such adjustment and
readjustment, showing in detail the facts upon which such adjustment or readjustment is based. The Company shall, upon written request
of the Holder, at any time, furnish or cause to be furnished to the Holder a like certificate setting forth such adjustments and readjustments,
the applicable Fixed Conversion Price in effect at the time, and the number of Common Stock and the amount, if any, of other securities
or property which at the time would be received upon the conversion of this Advance Note. Notwithstanding the foregoing, the Company shall
not be obligated to deliver a certificate unless such certificate would reflect an increase or decrease of at least one percent of such
adjusted amount.


 


(e) Issuance
Taxes. The Company shall pay any and all issuance and other taxes, excluding federal, state or local income taxes, that may be payable
in respect of any issue or delivery of Common Stock on conversion of this Advance Note pursuant thereto; provided, however,
that the Company shall not be obligated to pay any transfer taxes resulting from any transfer requested by the Holder in connection with
any such conversion.


 


(f) Reservation
of Common Stock. The Company shall at all times while this Advance Note shall be outstanding, reserve and keep available out of its
authorized but unissued Common Stock at least the Required Minimum of Common Stock (disregarding for this purpose any and all limitations
of any kind on such conversion). The Company shall, from time-to-time, increase the authorized number of Common Stock or take other effective
action if at any time the unissued number of authorized shares shall not be sufficient to satisfy the Company’s obligations under
this Section 3.3(f).


 






    B-14


     


    

 


(g) Regulatory
Compliance. If any Common Stock to be reserved for the purpose of conversion of this Advance Note requires registration or listing
with or approval of any governmental authority, national securities exchange or other regulatory body under any federal or state law or
regulation or otherwise before such shares may be validly issued or delivered upon conversion, the Company shall, at its sole cost and
expense, in good faith and as expeditiously as possible, secure such registration, listing or approval, as the case may be.


 


3.4 Rights
Upon Fundamental Transaction


 


(a) Assumption. 
The Company shall not enter into or be party to a Fundamental Transaction unless the Person (which may be the Company) formed by, resulting
from or surviving any Fundamental Transaction or the Person with which such Fundamental Transaction shall have been entered into (the
“Successor Entity”) assumes in writing all of the obligations of the Company under this Advance Note and the other
Transaction Documents in accordance with the provisions of this Section 3.4(a) pursuant to written agreements in form and substance reasonably
satisfactory to the Holder and approved by the Holder prior to such Fundamental Transaction, including agreements to deliver to each holder
of Advance Notes in exchange for such Advance Notes a security of the Successor Entity evidenced by a written instrument substantially
similar in form and substance to the Advance Notes, including, without limitation, having Principal and Interest equal to the Principal
then outstanding and any accrued and unpaid Interest thereon (if any) of the Advance Notes held by the Holder, having similar conversion
rights as the Advance Notes and having similar ranking and security to the Advance Notes on the Collateral. Upon the occurrence of any
Fundamental Transaction, the Successor Entity shall succeed to, and be substituted for (so that from and after the date of such Fundamental
Transaction, the provisions of this Advance Note 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 Advance Note and the other Transaction Documents with the same effect as if such Successor Entity had been named as
the Company herein.  Upon consummation of a Fundamental Transaction, the Successor Entity shall deliver to the Holder confirmation
that there shall be issued upon conversion or redemption of this Advance Note at any time after the consummation of such Fundamental Transaction,
in lieu of the shares of Common Stock issuable upon the conversion or redemption of this Advance Note prior to such Fundamental Transaction,
such shares of the common stock (or their equivalent), securities or other assets of the Successor Entity (including its parent entity)
which the Holder would have been entitled to receive upon the happening of such Fundamental Transaction had this Advance Note been converted
immediately prior to such Fundamental Transaction at the applicable Conversion Price in effect immediately prior to such Fundamental Transaction
(without regard to any limitations on the conversion of this Advance Note), as adjusted in accordance with the provisions of this Advance
Note. Notwithstanding the foregoing, the Holder may elect, at its sole option, by delivery of written notice to the Company to waive this
Section 3.4(a) to permit the Fundamental Transaction without the assumption of this Advance Note.  The provisions of this Section
3.4(a) shall apply similarly and equally to successive Fundamental Transactions and shall be applied without regard to any limitations
on the conversion of this Advance Note.


 


(b) Other
Corporate Events.  In addition to and not in substitution for any other rights hereunder (but without duplication of Section
3.4(a) or any adjustment pursuant to Section 3.3(a)(iv)), prior to the consummation of any 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 ensure that the Holder will thereafter have
the right to receive upon a conversion of this Advance Note, such securities or other assets to which the Holder would have been entitled
with respect to such shares of Common Stock issuable on conversion of this Advance Note, at the applicable Conversion Price in effect
immediately prior to such Corporate Event, had such shares of Common Stock been held by the Holder upon the consummation of such Corporate
Event (without taking into account any limitations or restrictions on the convertibility of this Advance Note). Provision made pursuant
to the preceding sentence shall be in a form and substance reasonably satisfactory to the Holder.  The provisions of this Section
3.4(b) shall apply similarly and equally to successive Corporate Events and shall be applied without regard to any limitations on the
conversion or redemption of this Advance Note or any other security beneficially owned by the Holder.


 






    B-15


     


    

 


(c) Prepayment
Following a Change of Control. No later than five Trading Days following the entry by the Company into an agreement for a Change of
Control but in no event prior to the public announcement of such Change of Control, the Company shall deliver written notice describing
the entry into such agreement (“Notice of Change of Control”) to the Holder. Within 30 days after receipt of a Notice
of Change of Control, the Holder may require the Company to prepay, effective immediately prior to the consummation of such Change of
Control, an amount equal to 105% of the sum of (x) the outstanding Principal of this Advance Note and (y) and any accrued and unpaid Interest
thereon (the “COC Repayment Price”), by delivering written notice thereof (“Notice of Prepayment at Option
of Holder Upon Change of Control”) to the Company.


 


(d) Payment of COC
Repayment Price. Upon the Company’s receipt of a Notice(s) of Prepayment at Option of Holder Upon Change of Control from
the Holder, the Company shall deliver the COC Repayment Price to the Holder immediately prior to the consummation of the Change of
Control; provided, that the Holder’s original of this Advance Note shall have been so delivered to the Company,
and, provided, further that all payments shall be subject to the provisions of the Purchase Agreement with respect to
the holders of the Other Advance Note and any Pre-Paid Tranches.


 


3.5 Inability
to Fully Convert.


 


(a) Holder’s
Option if Company Cannot Fully Convert. If, upon the Company’s receipt of a Notice of Conversion or as otherwise required under
this Advance Note, including with respect to repayment of Principal, the Company cannot issue all or any portion of the Common Stock due
on such conversion for any reason, including, without limitation, because the Company (x) does not have a sufficient number of shares
of Common Stock authorized and available or (y) is otherwise prohibited by applicable law or by the rules or regulations of any national
securities exchange, interdealer quotation system or other self-regulatory organization with jurisdiction over the Company or any of its
securities from issuing all of the shares of Common Stock which are to be issued to the Holder pursuant to this Advance Note, then the
Company shall issue as many shares of Common Stock as it is able to issue and, with respect to the unconverted portion of this Advance
Note or with respect to any Common Stock not timely issued in accordance with this Advance Note, the Holder, solely at Holder’s
option, can elect to:


 


(i) require
the Company to prepay that portion of this Advance Note for which the Company is unable to issue Common Stock or for which Common Stock
was not timely issued (the “Mandatory Prepayment”) at a price equal to the number of shares of Common Stock that the
Company is unable to issue multiplied by the VWAP on the date of the Notice of Conversion (provided all payments shall be subject to the
provisions of the Purchase Agreement with respect to the holders of the Other Advance Notes and any Pre-Paid Tranches); provided
that, notwithstanding anything in this Advance Note or the Purchase Agreement to the contrary, the payment of such amount shall cure any
breach or Event of Default arising from such failure to deliver shares of Common Stock on such conversion;


 


(ii) void
its Notice of Conversion and retain or have returned, as the case may be, this Advance Note or the portion of this Advance Note that was
to be converted pursuant to the Notice of Conversion (provided that the Holder’s voiding its Notice of Conversion shall not
affect the Company’s obligations to make any payments which have accrued prior to the date of such notice); or


 


(iii) defer
issuance of the applicable Conversion Shares until such time as the Company can legally issue such shares; provided that the Principal
and any accrued and unpaid Interest thereon underlying such Conversion Shares shall remain outstanding until the delivery of such Conversion
Shares; and provided, further, that if the Holder elects to defer the issuance of the Conversion Shares, it may exercise
its rights under either clause (i) or (ii) above at any time prior to the issuance of the Conversion Shares upon two Trading Days’

(b) Mechanics
of Fulfilling Holder’s Election. The Company shall immediately send to the Holder, upon receipt of a Notice of Conversion from
the Holder, which cannot be fully satisfied as described in Section 3.6(a) above, a notice of the Company’s inability to fully satisfy
the Notice of Conversion (the “Inability to Fully Convert Notice”). Such Inability to Fully Convert Notice shall indicate
(i) the reason why the Company is unable to fully satisfy the Holder’s Notice of Conversion; and (ii) the amount of this Advance
Note which cannot be converted. The Holder shall notify the Company of its election pursuant to Section 3.5(a) above by delivering written
notice to the Company (“Notice in Response to Inability to Convert”).


 


(c) Payment
of Mandatory Prepayment Price. If the Holder shall elect to have its Advance Note prepaid pursuant to Section 3.2(c) or 3.5(a)(i)
above, the Company shall pay the Mandatory Prepayment Price to the Holder within five Trading Days of the Company’s receipt of the
Holder’s request for payment of the Mandatory Prepayment Price on a Conversion Failure or Notice in Response to Inability to Convert;
provided that prior to the Company’s receipt of the Holder’s request for payment of the Mandatory Prepayment Price
on a Conversion Failure or Notice in Response to Inability to Convert, as applicable, the Company has not delivered a notice to the Holder
stating, to the satisfaction of the Holder, that the event or condition resulting in the Mandatory Prepayment has been cured and all Conversion
Shares issuable to the Holder can and will be delivered to the Holder in accordance with the terms of this Advance Note.


 


(d) Purchase
Rights. If at any time the Company grants, issues or sells any options, other convertible securities or rights to purchase stock,
warrants, securities or other property pro rata to all or substantially all of the record holders of Common Stock (the “Purchase
Rights”), then the Holder will be entitled to acquire, upon the terms applicable to such Purchase Rights, the aggregate Purchase
Rights which the Holder could have acquired if the Holder had held the number of shares of Common Stock acquirable upon complete conversion
of this Advance Note (without taking into account any limitations or restrictions on the convertibility of this Advance Note) immediately
prior to the date on which a record is taken for the grant, issuance or sale of such Purchase Rights, or, if no such record is taken,
the date as of which the record holders of shares of Common Stock are to be determined for the grant, issue or sale of such Purchase Rights
(provided, however, that to the extent that the Holder’s right to participate in any such Purchase Right would result
in the Holder 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 to the extent of any such excess) and such Purchase Right to such extent shall be held in abeyance
(and, if such Purchase Right has an expiration date, maturity date or other similar provision, such term shall be extended by such number
of days held in abeyance, if applicable) 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 (and, if such Purchase Right has an expiration date, maturity date or other similar provision, such term shall be extended
by such number of days held in abeyance, if applicable)) to the same extent as if there had been no such limitation).


 


(e) No
Rights as Shareholder. Nothing contained in this Advance Note shall be construed as conferring upon the Holder, prior to the conversion
of this Advance Note, the right to vote or to receive dividends or to consent or to receive notice as a shareholder of the Company in
respect of any meeting of shareholders for the election of directors of the Company or of any other matter, or any other rights as a shareholder
of the Company.

COMMON STOCK PURCHASE
WARRANT


Ascent
Solar Technologies, Inc.


 


	Warrant
    Shares: 	 	 	Exercise
Price: $3.93	 
	 	 	 	Initial Exercise Date: December
19, 2022	 



 


THIS COMMON STOCK PURCHASE WARRANT
(this “Warrant”) certifies that, for value received, ___________________ or its assigns (the “Holder”) is entitled,
upon the terms and subject to the limitations on exercise and the conditions hereinafter set forth, to subscribe for and purchase from
Ascent Solar Technologies, Inc., a Delaware corporation (the “Company”), _________ shares of Common Stock (subject to adjustment
hereunder, the “Warrant Shares”) at any time on or after the date hereof (the “Initial Exercise Date”) and on
or prior to the close of business on the five year anniversary of the Initial Exercise Date (the “Termination Date”) but not
thereafter.


 


The purchase price of one
Warrant Share under this Warrant shall be equal to the Exercise Price, as defined in Section 2(b).


 


Section 1. Definitions.
Capitalized terms used and not otherwise defined herein shall have the meanings set forth in that certain Securities Purchase Contract
(the “Purchase Contract”), dated December 19, 2022, between the Company and the Holder.


 


Section 2. Exercise.


 


(a)   Exercise
of the purchase rights represented by this Warrant may be made, in whole or in part, at any time or times on or after the Initial Exercise
Date and on or before the Termination Date by delivery to the Company (or such other office or agency of the Company as it may designate
by notice in writing to the registered Holder at the address of the Holder appearing on the books of the Company) of a duly executed facsimile
or .pdf electronic copy of the Notice of Exercise Form annexed hereto (the “Notice of Exercise”). Within the earlier of (i)
two Trading Days following the date of exercise as aforesaid or (ii) the Standard Settlement Period, the Holder shall deliver the aggregate
Exercise Price for the shares specified in the applicable Notice of Exercise by wire transfer or cashier’s check drawn on a United
States bank unless the cashless exercise procedure specified in Section 2(c) below is specified in the applicable Notice of Exercise.
In the event that the Holder is required to make any payments to the Company’s stock transfer agent in connection with its exercise
of this Warrant resulting from any failure of the Company to pay the transfer agent, the Holder may deduct such sums it pays the transfer
agent from the total Exercise Price due. Notwithstanding anything herein to the contrary (although the Holder may surrender the Warrant
to, and receive a replacement Warrant from, the Company), the Holder shall not be required to physically surrender this Warrant to the
Company until the Holder has purchased all of the Warrant Shares available hereunder and the Warrant has been exercised in full, in which
case, the Holder shall surrender this Warrant to the Company for cancellation within five Trading Days of the date the final Notice of
Exercise is delivered to the Company. Partial exercises of this Warrant resulting in purchases of a portion of the total number of Warrant
Shares available hereunder shall have the effect of lowering the outstanding number of Warrant Shares purchasable hereunder in an amount
equal to the applicable number of Warrant Shares purchased. The Holder and the Company shall maintain records showing the number of Warrant
Shares purchased and the date of such purchases. The Company shall deliver any objection to any Notice of Exercise Form within two Trading
Days of delivery of such notice. The Holder, by acceptance of this Warrant, acknowledges and agrees that, by reason of the provisions
of this paragraph, following the purchase of a portion of the Warrant Shares hereunder, the number of Warrant Shares available for purchase
hereunder at any given time may be less than the amount stated on the face hereof.


 






    C-1


     


    

 


(b)   Exercise
Price. The initial exercise price per share of the Common Stock under this Warrant shall be equal to $3.93 per share, subject to adjustment
as provided herein (the “Exercise Price”).


 


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


 


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


 


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


 


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


 


If
Warrant Shares are issued in such a cashless exercise, the parties acknowledge and agree that in accordance with Section 3(a)(9) of the
Securities Act of 1933 (together with the rules and regulations promulgated thereunder, the “Securities Act”), the Warrant
Shares shall take on the characteristics of the Warrants being exercised, and the holding period of the Warrants being exercised may be
tacked on to the holding period of the Warrant Shares. The Company agrees not to take any position contrary to this Section 2(c).


 


For avoidance of doubt, the
phrase “effective Registration Statement” means (i) a registration statement covering the resale of the Warrant Shares has
been declared effective by the SEC, has not been withdrawn and is not subject to a stop order issued by the SEC, and (ii) the Prospectus
contained in such registration statement complies with Sections 5(b) and 10 of the Securities Act.


 


(d)   Mechanics
of Exercise.


 


(i)   Delivery
of Shares Upon Exercise. The Warrant Shares purchased hereunder shall be transmitted to the Holder (A) by the Transfer Agent by crediting
the account of the Holder’s prime broker with The Depository Trust Company through its Deposit or Withdrawal at Custodian system
(“DWAC”) if the Company is then a participant in such system and (i) there is an effective Registration Statement covering
the resale of the Warrant Shares by the Holder, or (ii) this Warrant is being exercised via cashless exercise and Rule 144 under the Securities
Act is available for resales of the Warrant Shares by the Holder without any volume or manner-of-sale restrictions or current public information
requirements under Rule 144, or (B) otherwise, by physical delivery of a certificate, registered in the Company’s share register
in the name of the Holder or its designee, for the number of Warrant Shares to which the Holder is entitled pursuant to such exercise
to the address specified by the Holder in the Notice of Exercise by the date that is two Trading Days after the later of (x) the delivery
to the Company of the Notice of Exercise and (y) payment of the aggregate Exercise Price as set forth above (unless by cashless exercise,
if permitted) (such date, the “Warrant Share Delivery Date”). The Warrant Shares shall be deemed to have been issued, and
the Holder or any other person so designated to be named therein shall be deemed to have become a holder of record of such shares for
all purposes, as of the date the Warrant has been exercised, with payment to the Company of the Exercise Price (unless by cashless exercise,
if permitted) and all taxes required to be paid by the Holder, if any, pursuant to Section 2(d)(vi) prior to the issuance of such shares,
having been paid. The Company understands that a delay in the delivery of the Warrant Shares after the Warrant Share Delivery Date could
result in economic loss to the Holder. As compensation to the Holder for such loss, the Company agrees to pay (as liquidated damages and
not as a penalty) to the Holder for late issuance of Warrant Shares upon exercise of this Warrant the proportionate amount of $5 per Trading
Day (increasing to $10 per Trading Day after the fifth Trading Day) after the Warrant Share Delivery Date for each $1,000 of the value
of the Warrant Shares for which this Warrant is exercised (based on the Exercise Price and including, if applicable, after giving effect
to any cashless exercise of the Warrant) which are not timely delivered. The Company shall pay any payment incurred under this Section
2(d)(i) in immediately available funds reasonably promptly following demand by the Holder. Furthermore, in addition to any other remedies
which may be available to the Holder, in the event that the Company fails for any reason to effect delivery of the Warrant Shares by the
Warrant Share Delivery Date, the Holder may, at any time prior to issuance of such Warrant Shares, revoke all or part of the relevant
Warrant exercise by delivery of a notice to such effect to the Company, whereupon the Company and the Holder shall each be restored to
their respective positions immediately prior to the exercise of the relevant portion of this Warrant except that the liquidated damages
described above shall be payable through the date the notice of revocation or rescission is given to the Company or the date the Warrant
Shares are delivered to the Holder, whichever date is earlier.


 






    C-2


     


    

 


(ii)   Delivery
of New Warrants Upon Exercise. If this Warrant shall have been exercised in part, the Company shall not require the Holder to surrender
this Warrant as a condition of exercise. If the Holder requests a new Warrant, it shall surrender this Warrant, and the Company shall
deliver to the Holder a new Warrant evidencing the rights of the Holder to purchase the unpurchased Warrant Shares called for by this
Warrant, which new Warrant shall in all other respects be identical to this Warrant.


 


(iii)   [Reserved]


 


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


 


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


 


(vi)   Charges,
Taxes and Expenses. Issuance of Warrant Shares shall be made without charge to the Holder for any issue or transfer tax or other incidental
expense in respect of the issuance of such Warrant Shares including any charges (limited to $100 per issuance) of any clearing firm, all
of which taxes and expenses shall be paid by the Company, and such certificates shall be issued in the name of the Holder or in such name
or names as may be directed by the Holder; provided, however, that in the event certificates for Warrant Shares are to be
issued in a name other than the name of the Holder, this Warrant when surrendered for exercise shall be accompanied by the Assignment
Form attached hereto duly executed by the Holder and the Company may require, as a condition thereto, the payment of a sum sufficient
to reimburse it for any transfer tax incidental thereto. The Company shall pay all Transfer Agent fees required for same-day processing
of any Notice of Exercise.


 






    C-3


     


    

 


(e)   Holder’s
Exercise Limitations. 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 (as defined in the Advance) 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, Advances, Prepaid-Tranches, or convertible preferred stock or warrants, including
other Warrants issued under the Purchase Contract) 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 2(e). For purposes of this Section 2(e), beneficial ownership
shall be calculated in accordance with Section 13(d) of the Securities and Exchange Act of 1934, as amended (together with the rules and
regulations promulgated thereunder, the “Exchange 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 2(e), 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, if any, 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) Trading 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 Exchange 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, if any, for the Excess Shares. To the extent that the limitation contained in this Section 2(e) applies, the determination
of whether this Warrant is exercisable (in relation to other securities owned by the Holder together with any Affiliates and Attribution
Parties) and of which portion of this Warrant is exercisable shall be in the sole discretion of the Holder, and the submission of a Notice
of Exercise shall be deemed to be the Holder’s determination of whether this Warrant is exercisable (in relation to other securities
owned by the Holder together with any Affiliates and Attribution Parties) and of which portion of this Warrant is exercisable, in each
case subject to the Beneficial Ownership Limitation, and the Company shall have no obligation to verify or confirm the accuracy of such
determination. Provided, however, in the event that the Company’s transfer agent supplies incorrect information to
the Holder, the Company shall indemnify the Holder in accordance with the Purchase Contract for any damages sustained by the Holder. 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 Warrants (as defined in the Purchase Contract) 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 Exchange 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
not be construed and implemented in a manner otherwise than in strict conformity with the terms of this Section 2(e) 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 2(e) 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.


 






    C-4


     


    

 


Section 3. Certain
Adjustments.


 


(a)   Stock
Dividends and Splits. If the Company, at any time while this Warrant is outstanding: (i) pays a stock dividend or otherwise makes
a distribution or distributions on shares of its Common Stock or any other equity or equity equivalent securities payable in shares of
Common Stock (which, for avoidance of doubt, shall not include any shares of Common Stock issued by the Company upon exercise of this
Warrant or pursuant to any of the other Transaction Documents), (ii) subdivides outstanding shares of Common Stock into a larger number
of shares, (iii) combines (including by way of reverse stock split) outstanding shares of Common Stock into a smaller number of shares,
or (iv) issues by reclassification of shares of the Common Stock any shares of capital stock of the Company, then in each case the Exercise
Price shall be multiplied by a fraction of which the numerator shall be the number of shares of Common Stock (excluding treasury shares,
if any) outstanding immediately before such event and of which the denominator shall be the number of shares of Common Stock outstanding
immediately after such event, and the number of shares issuable upon exercise of this Warrant shall be proportionately adjusted such that
the aggregate Exercise Price of this Warrant shall remain unchanged. Any adjustment made pursuant to this Section 3(a) shall become effective
immediately after the record date for the determination of stockholders entitled to receive such dividend or distribution and shall become
effective immediately after the effective date in the case of a subdivision, combination or re-classification.


 


(b)   Adjustments
for Issuance of Additional Securities. If the Company at any time while this Warrant or the Advances are outstanding, issues or sells
any additional shares of Common Stock or Common Stock Equivalents (“Additional Shares of Common Stock”) in a transaction other
than an Exempt Issuance, at a price per share less than the Exercise Price then in effect or without consideration (a “Dilutive
Issuance” based on a “Dilutive Issuance Price”), then the Exercise Price upon each such issuance shall be reduced to
the lower of (i) an amount equal to the Dilutive Issuance Price, or (ii) the VWAP on the next Trading Day following the first public disclosure
of the Dilutive Issuance, (such lower price being the “New Exercise Price.”). Additionally, the number of Warrant Shares issuable
hereunder shall be determined by multiplying the Exercise Price then in effect immediately prior to such adjustment by the number of Warrant
Shares issuable upon exercise of this Warrant immediately prior to such adjustment and dividing the product thereof by the New Exercise
Price resulting from such adjustment. By way of example, if E is the total number of Warrant Shares in effect immediately prior to such
Dilutive Issuance, F is the Exercise Price in effect immediately prior to such Dilutive Issuance, and G is the New Exercise Price, the
adjustment to the number of Warrant Shares can be expressed in the following formula: Total number of Warrant Shares after such Dilutive
Issuance = the number obtained from dividing [E x F] by G. For the purposes of this Section 3(b), the next Trading Day if an announcement
is made before 4:00 pm New York, NY time is either the day of the announcement or the following Trading Day.


 


In case any Common Stock Equivalent
is issued in connection with the issue or sale of other securities of the Company, together comprising one integrated transaction, at
a price per unit that is less than the Exercise Price then in effect, then the shares of Common Stock issuable upon the conversion, exercise
or exchange of any such Common Stock Equivalent issued or sold in such integrated transaction shall be deemed to have been issued or sold
by the Company at the time of the issuance or sale of such Common Stock Equivalent for such price per unit and, immediately after such
issuance, the Exercise Price then in effect shall be reduced to the lower of (i) an amount equal to the price per unit issuable in such
transaction, or (ii) the average of the VWAPs of the Common Stock over the five Trading Days following the first public disclosure of
such transaction. Any indebtedness shall be valued at the principal less any original issue discount. If multiple shares of Common Stock
are contained in a unit, the aggregate consideration shall be divided by the number of shares of Common Stock in a unit. If any shares
of Common Stock or Common Stock Equivalents are issued or sold or deemed to have been issued or sold for cash, the amount of such consideration
received by the Company will be deemed to be the net amount received by the Company therefor. If any shares of Common Stock or Common
Stock Equivalents are issued or sold for a consideration other than cash, the amount of such consideration received by the Company will
be the fair value of such consideration, except where such consideration consists of publicly traded securities, in which case the amount
of consideration received by the Company will be the VWAP of such public traded securities on the date of receipt. If any shares of Common
Stock or Common Stock Equivalents are issued to the owners of the non-surviving entity in connection with any merger in which the Company
is the surviving entity, the amount of consideration therefor will be deemed to be the fair value of such portion of the net assets and
business of the non-surviving entity as is attributable to such shares of Common Stock or Common Stock Equivalents, as the case may be.
No further adjustment of the Exercise Price shall be made upon the actual issuance of such shares of Common Stock upon the conversion,
exercise or exchange of any such Common Stock Equivalent.


 






    C-5


     


    

 


The provisions of this Section
3(b) shall apply each time the Company, at any time after the Initial Exercise Date and while this Warrant or the Advances are outstanding,
shall issue any securities with a Dilutive Issuance Price. Notwithstanding the foregoing, no adjustment shall be made pursuant
to this Section 3(b) with respect to an Exempt Issuance.


 


(c)   Adjustment
upon Event of Default. Upon the occurrence and during the continuance of an Event of Default (as defined in the Advance), the Holder
may, at the Holder’s option, elect to exercise this Warrant at an Exercise Price equal to the Alternate Subscription Price (as defined
in the Advance). The Company shall give the Holder prompt written notice of the occurrence of an Event of Default.


 


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


 


(e)   Pro
Rata Distributions. If the Company, at any time while this Warrant is outstanding, shall distribute to all holders of Common Stock
(and not to the Holder) evidences of its indebtedness or assets (including cash and cash dividends) or rights or warrants to subscribe
for or purchase any security other than the Common Stock, then in each such case the Exercise Price shall be adjusted by multiplying the
Exercise Price in effect immediately prior to the record date fixed for determination of stockholders entitled to receive such distribution
by a fraction of which the denominator shall be the VWAP determined as of the record date mentioned above, and of which the numerator
shall be such VWAP on such record date less the then per share fair market value at such record date of the portion of such assets or
evidence of indebtedness so distributed applicable to one outstanding share of the Common Stock as determined by the Board of Directors
in good faith. In either case the adjustments shall be described in a statement provided to the Holder of the portion of assets or evidences
of indebtedness so distributed or such subscription rights applicable to one share of Common Stock. Such adjustment shall be made whenever
any such distribution is made and shall become effective immediately after the record date mentioned above.


 






    C-6


     


    

 


(f)   Fundamental
Transaction. If, at any time while this Warrant is outstanding, the Company enters into a Fundamental Transaction (as defined in the
Purchase Contract pursuant to which this Warrant was issued), then, upon any subsequent exercise of this Warrant, the Holder shall have
the right to receive, for each Warrant Share that would have been issuable upon such exercise immediately prior to the occurrence of such
Fundamental Transaction, at the option of the Holder (without regard to any limitation in Section 2(e) on the exercise of this
Warrant), the number of shares of Common Stock of the successor or acquiring corporation or of the Company, if it is the surviving corporation,
and any additional consideration (the “Alternate Consideration”) receivable as a result of such Fundamental Transaction by
a holder of the number of shares of Common Stock for which this Warrant is exercisable immediately prior to such Fundamental Transaction
(without regard to any limitation in Section 2(e) on the exercise of this Warrant). For purposes of any such exercise, the determination
of the Exercise Price shall be appropriately adjusted to apply to such Alternate Consideration based on the amount of Alternate Consideration
issuable in respect of one share of Common Stock in such Fundamental Transaction, and the Company shall apportion the Exercise Price among
the Alternate Consideration in a reasonable manner reflecting the relative value of any different components of the Alternate Consideration.
If holders of Common Stock are given any choice as to the securities, cash or property to be received in a Fundamental Transaction, then
the Holder shall be given the same choice as to the Alternate Consideration it receives upon any exercise of this Warrant following such
Fundamental Transaction. Notwithstanding anything to the contrary, in the event of a Fundamental Transaction, the Company or any Successor
Entity (as defined below) shall, at its option, exercisable at any time concurrently with, or within 30 days after, the consummation of
the Fundamental Transaction (or, if later, the date of the public announcement of the applicable Fundamental Transaction), purchase this
Warrant from the Holder by paying to the Holder an amount of cash equal to the Black Scholes Value (as defined below) of the remaining
unexercised portion of this Warrant on the date of the consummation of such Fundamental Transaction; provided, however,
that, if the Fundamental Transaction is not within the Company’s control, including not approved by the Company’s Board of
Directors, Holder shall only be entitled to receive from the Company or any Successor Entity the same type or form of consideration (and
in the same proportion), at the Black Scholes Value of the unexercised portion of this Warrant, that is being offered and paid to the
holders of Common Stock of the Company in connection with the Fundamental Transaction, whether that consideration be in the form of cash,
stock or any combination thereof, or whether the holders of Common Stock are given the choice to receive from among alternative forms
of consideration in connection with the Fundamental Transaction; provided, further, that if holders of Common
Stock of the Company are not offered or paid any consideration in such Fundamental Transaction, such holders of Common Stock will be deemed
to have received common stock of the Successor Entity (which Entity may be the Company following such Fundamental Transaction) in such
Fundamental Transaction. “Black Scholes Value” means the value of this Warrant based on the Black-Scholes Option Pricing Model
obtained from the “OV” function on Bloomberg, L.P. (“Bloomberg”) determined as of the day of consummation of the
applicable contemplated Fundamental Transaction for pricing purposes and reflecting (A) a risk-free interest rate corresponding to
the U.S. Treasury rate for a period equal to the time between the date of the public announcement of the applicable Fundamental Transaction
and the Termination Date, (B) an expected volatility equal to the greater of 100% and the 100 day volatility obtained from the HVT
function on Bloomberg (determined utilizing a 365 day annualization factor) as of the Trading Day immediately following the public announcement
of the applicable contemplated Fundamental Transaction, (C) the underlying price per share used in such calculation shall be the
greater of (i) the sum of the price per share being offered in cash, if any, plus the value of any non-cash consideration, if any,
being offered in such Fundamental Transaction and (ii) the highest VWAP during the period beginning on the Trading Day immediately
prior to the public announcement of such Fundamental Transaction and ending on the Trading Day of the Holder’s request pursuant
to this Section 3(f), (D) a remaining option time equal to the time between the date of the public announcement of the applicable
Fundamental Transaction and the Termination Date and (E) a zero cost of borrow. The payment of the Black Scholes Value will be made
by wire transfer of immediately available funds (or such other consideration) within five Trading Days of the Holder’s election
(or, if later, on the date of consummation of the Fundamental Transaction). The Company shall cause any successor entity in a Fundamental
Transaction in which the Company is not the survivor (the “Successor Entity”) to assume in writing all of the obligations
of the Company under this Warrant in accordance with the provisions of this Section 3(f) pursuant to written agreements in form
and substance reasonably satisfactory to the Holder and approved by the Holder (without unreasonable delay) prior to such Fundamental
Transaction and shall, at the option of the Holder, deliver to the Holder in exchange for this Warrant a security of the Successor Entity
evidenced by a written instrument substantially similar in form and substance to this Warrant which is exercisable for a corresponding
number of shares of capital stock of such Successor Entity (or its parent entity) equivalent to the shares of Common Stock acquirable
and receivable upon exercise of this Warrant (without regard to any limitations on the exercise of this Warrant) prior to such Fundamental
Transaction, and with an exercise price which applies the exercise price hereunder to such shares of capital stock (but taking into account
the relative value of the shares of Common Stock pursuant to such Fundamental Transaction and the value of such shares of capital stock,
such number of shares of capital stock and such exercise price being for the purpose of protecting the economic value of this Warrant
immediately prior to the consummation of such Fundamental Transaction), and which is reasonably satisfactory in form and substance to
the Holder. Upon the occurrence of any such Fundamental Transaction, the Successor Entity shall succeed to, and be substituted for (so
that from and after the date of such Fundamental Transaction, the provisions of this Warrant referring to the “Company” shall
refer instead to the Successor Entity), and may exercise every right and power of the Company and shall assume all of the obligations
of the Company under this Warrant with the same effect as if such Successor Entity had been named as the Company herein.


 






    C-7


     


    

 


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


 


(h)   Notice
to Holder.


 


(i)   Adjustment
to Exercise Price. Whenever the Exercise Price is adjusted pursuant to any provision of this Section 3, the Company shall promptly
email to the Holder a notice setting forth the Exercise Price after such adjustment and any resulting adjustment to the number of Warrant
Shares and setting forth a brief statement of the facts requiring such adjustment. The Holder may supply an email address to the Company
and change such address.


 


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


 


Section 4. Transfer
of Warrant.


 


(a)   Transferability.
Subject to compliance with any applicable securities laws and the provisions of the Purchase Contract, this Warrant and all rights hereunder
are transferable, in whole or in part, upon surrender of this Warrant at the principal office of the Company or its designated agent,
together with a written assignment of this Warrant substantially in the form attached hereto duly executed by the Holder or its agent
or attorney and funds sufficient to pay any transfer taxes payable upon the making of such transfer. Upon such surrender and, if required,
such payment, the Company shall execute and deliver a new Warrant or Warrants in the name of the assignee or assignees, as applicable,
and in the denomination or denominations specified in such instrument of assignment, and shall issue to the assignor a new Warrant evidencing
the portion of this Warrant not so assigned, and this Warrant shall promptly be cancelled. The Warrant, if properly assigned in accordance
herewith, may be exercised by a new holder for the purchase of Warrant Shares without having a new Warrant issued.


 






    C-8


     


    

 


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


 


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


 


(d)   Transfer
Restrictions. If, at the time of the surrender of this Warrant in connection with any transfer of this Warrant or upon exercise of
this Warrant, the transfer of this Warrant or the resale of the Warrant Shares, as applicable, shall not be either (i) registered pursuant
to an effective registration statement under the Securities Act and under applicable state securities or blue sky laws or (ii) eligible
for resale without volume or manner-of-sale restrictions or current public information requirements pursuant to Rule 144, the Company
may require, as a condition of allowing such transfer, that the Holder or transferee of this Warrant, as the case may be, make usual and
customary representations as to investment intent to the Company. For the avoidance of doubt, the delivery of a Notice of Exercise in
the form attached hereto containing such customary representations shall satisfy this Section 4(d).


 


(e)   Representation
by the Holder. The Holder, by the acceptance hereof, represents and warrants that it is acquiring this Warrant and, upon any exercise
hereof at a time when the Warrant Shares are not either (i) registered for resale pursuant to an effective registration statement under
the Securities Act and under applicable state securities or blue sky laws or (ii) eligible for resale without volume or manner-of-sale
restrictions or current public information requirements pursuant to Rule 144, will acquire the Warrant Shares issuable upon such exercise,
for its own account and not with a view to or for distributing or reselling such Warrant Shares or any part thereof in violation of the
Securities Act or any applicable state securities law, except pursuant to sales registered or exempted under the Securities Act.


 


Section 5. Miscellaneous.


 


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


 


(b)   Loss,
Theft, Destruction or Mutilation of Warrant. The Company covenants that upon receipt by the Company of evidence reasonably satisfactory
to it of the loss, theft, destruction or mutilation of this Warrant or any stock certificate relating to the Warrant Shares (in each case,
to the extent an original of this Warrant or a physical stock certificate relating to the Warrant Shares had been delivered to the Holder),
and upon surrender and cancellation of such Warrant or stock certificate, if mutilated, the Company will make and deliver a new Warrant
or stock certificate of like tenor and dated as of such cancellation, in lieu of such Warrant or stock certificate. In no event shall
the Holder be required to post a bond or other security.


 


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


 






    C-9


     


    

 


(d)   Authorized
Shares.


 


The Company covenants that
during the period this Warrant is outstanding, it will comply with Section 4.11 of the Purchase Contract with respect to reserving the
Warrant Shares, subject to adjustment pursuant to Section 3. The Company further covenants that its issuance of this Warrant shall constitute
full authority to its officers who are charged with the duty of executing stock certificates to execute and issue the necessary certificates
for the Warrant Shares (or to direct the issuance of such Warrant Shares to the Holder in book-entry form) upon the exercise of the purchase
rights under this Warrant. The Company will take all such reasonable action as may be necessary to assure that such Warrant Shares may
be issued as provided herein without violation of any applicable law or regulation, or of any requirements of any Trading Market upon
which the Common Stock may be listed. The Company covenants that all Warrant Shares which may be issued upon the exercise of the purchase
rights represented by this Warrant will, upon exercise of the purchase rights represented by this Warrant and payment for such Warrant
Shares in accordance herewith, be duly authorized, validly issued, fully paid and non-assessable and free from all taxes, liens and charges
created by the Company in respect of the issue thereof (other than taxes in respect of any transfer occurring contemporaneously with such
issue).


 


In addition to any other remedies
provided by this Warrant or the Agreement, if the Company at any time fails to meet this reservation of Common Stock requirement within
45 days after written notice from the Holder, it shall pay the Holder as partial liquidated damages and not as a penalty a sum equal to
$250 per day for each $100,000 of such Holder’s Subscription Amount (or the Subscription Amount of the original Purchaser) under
the Transaction Documents. The Company shall not enter into any agreement or file any amendment to its Certificate of Incorporation (including
the filing of a Certificate of Designation) which conflicts with this Section 5(d) while the Advances and Warrants remain outstanding;
provided, that nothing shall prohibit or otherwise restrict the Company from amending its Certificate of Incorporation in connection with
the Corporate Reorganization.


 


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


 


(e)   Choice
of Law; Jurisdiction. All questions concerning the construction, validity, enforcement and interpretation of this Warrant and the
exclusive jurisdiction for resolutions of any disputes arising from or relating to the issuance of or interpretation of this Warrant shall
be determined in accordance with the provisions of the Purchase Contract.


 


(f)   Restrictions.
The Holder acknowledges that the Warrant Shares acquired upon the exercise of this Warrant, if not registered or if not exercised on a
cashless basis when Rule 144 is available for resales of the Warrant Shares by the Holder without any volume or manner-of-sale restrictions
or current public information requirements under Rule 144, will have restrictions upon resale imposed by state and federal securities
laws.


 


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


 






    C-10


     


    

 


(h)   Notices.
Any notice, request or other document required or permitted to be given or delivered to the Holder by the Company shall be delivered in
accordance with the notice provisions of the Purchase Contract. Any and all notices or other communications or deliveries required or
permitted to be provided hereunder shall be in writing and shall be deemed given and effective on the earliest of: (a) the time of transmission,
if such notice or communication is delivered via email at the email address as set forth on the signature pages attached to the Purchase
Contract at or prior to 5:30 p.m. (New York, N.Y. time) on a Trading Day, (b) the next Trading Day after the time of transmission, if
such notice or communication is delivered via email at the email address as set forth on the signature pages attached to the Purchase
Contract on a day that is not a Trading Day or later than 5:30 p.m. (New York, N.Y. time) on any Trading Day, (c) the second Trading Day
following the date of mailing, if also sent by U.S. nationally recognized overnight courier service or (d) upon actual receipt by the
party to whom such notice is required to be given. The address for such notices and communications shall be as set forth on the signature
pages attached to this Warrant or the applicable Assignment Form following any transfer hereof.


 


(i)   Limitation
of Liability. No provision hereof, in the absence of any affirmative action by the Holder to exercise this Warrant to purchase Warrant
Shares, and no enumeration herein of the rights or privileges of the Holder, shall give rise to any liability of the Holder for the purchase
price of any Common Stock or as a stockholder of the Company, whether such liability is asserted by the Company or by creditors of the
Company.


 


(j)   Remedies.
The Holder, in addition to being entitled to exercise all rights granted by law, including recovery of damages, will be entitled to specific
performance of its rights under this Warrant. The Company agrees that monetary damages would not be adequate compensation for any loss
incurred by reason of a breach by it of the provisions of this Warrant and hereby agrees to waive and not to assert the defense in any
action for specific performance that a remedy at law would be adequate or that there is no irreparable harm and not to require the posting
of a bond or other security.


 


(k)   Successors
and Assigns. Subject to applicable securities laws, this Warrant and the rights and obligations evidenced hereby shall inure to the
benefit of and be binding upon the successors and permitted assigns of the Company and the successors and permitted assigns of Holder.
The provisions of this Warrant are intended to be for the benefit of any Holder from time to time of this Warrant and shall be enforceable
by any Holder from time to time of this Warrant or any Warrant Shares.


 


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


 


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


 


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

interest, provided that notices to account debtors in respect of any Accounts or Instruments shall be subject to the provisions

asset comprised in the Collateral falls within the scope of Article 9 of the UCC, or (B) as being of an equal or lesser scope or with
greater detail, and (ii) contain any other information required by part 5 of Article 9 of the UCC for the sufficiency or filing office

or (ii) become entitled to the benefit of any registered Copyrights or any Patents or Trademarks or any improvement on any Patent, the
provisions of this Agreement above shall automatically apply thereto and such Debtor shall give to the Collateral Agent prompt written

not said UCC is in effect in the jurisdiction where the rights and remedies are asserted) and such additional rights and remedies to which
a secured party is entitled under the laws in effect in any jurisdiction where any rights and remedies hereunder may be asserted, including,
without limitation, the right, to the maximum extent permitted by law, to: (i) exercise all voting, consensual and other powers of ownership

the Collateral or business of a Debtor, whether such receivership be incident to a proposed sale or sales of such Collateral or otherwise
and without regard to the value of the Collateral or the solvency of any person or persons liable for the payment of the Obligations secured
by such Collateral. Each Debtor hereby consents to the appointment of such receiver or receivers, waives any and all defenses to such
appointment and agrees that such appointment shall in no manner impair, prejudice or otherwise affect the rights of the Collateral Agent
or any Secured Party under this Agreement. Each Debtor hereby expressly waives notice of a hearing for appointment of a receiver and the
necessity for bond or an accounting by the receiver;

(f) the
Collateral Agent may, upon reasonable notice (such reasonable notice to be determined by the Collateral Agent in its sole and absolute
discretion, which shall not be less than 10 days), with respect to the Collateral or any part thereof which shall then be or shall thereafter
come into the possession, custody or control of the Collateral Agent or its Representative, sell, lease, license, assign or otherwise
dispose of all or any part of such Collateral, at such place or places as the Collateral Agent deems best, and for cash or for credit
or for future delivery (without thereby assuming any credit risk), at public or private sale, without demand of performance or notice
of intention to effect any such disposition or of the time or place thereof (except such notice as is required above or by applicable
statute and cannot be waived), and the Collateral Agent or anyone else may be the purchaser, lessee, licensee, assignee or recipient of
any or all of the Collateral so disposed of at any public sale (or, to the extent permitted by law, at any private sale) and thereafter
hold the same absolutely, free from any claim or right of whatsoever kind, including any right or equity of redemption (statutory or otherwise),
of Debtors, any such demand, notice and right or equity being hereby expressly waived and released. The Collateral Agent may, without
notice or publication, adjourn any public or private sale or cause the same to be adjourned from time to time by announcement at the time

disposition under this Section 4.5 shall be applied in accordance with Section 4.8 hereof.

4.7 Private
Sale. Each Debtor recognizes that the Collateral Agent may be unable to effect a public sale of any or all of the Collateral consisting
of securities by reason of certain prohibitions contained in the Securities Act of 1933, as amended (the “Act”), and
applicable state securities laws, but may be compelled to resort to one or more private sales thereof to a restricted group of purchasers
who will be obliged to agree, among other things, to acquire such Collateral for their own account for investment and not with a view
to the distribution or resale thereof. Each Debtor acknowledges and agrees that any such private sale may result in prices and other terms
less favorable to the seller than if such sale were a public sale and each Debtor agrees that it is not commercially unreasonable for
the Collateral Agent to engage in any such private sales or dispositions under such circumstances. The Collateral Agent shall be under
no obligation to delay a sale of any of the Collateral to permit a Debtor to register such Collateral for public sale under the Act, or
under applicable state securities laws, even if Debtors would agree to do so. The Collateral Agent shall not incur any liability as a
result of the sale of any such Collateral, or any part thereof, at any private sale provided for in this Agreement conducted in a commercially
reasonable manner, and so long as the Collateral Agent conducts such sale in a commercially reasonable manner each Debtor hereby waives
any claims against the Collateral Agent or any Secured Party arising by reason of the fact that the price at which the Collateral may
have been sold at such a private sale was less than the price which might have been obtained at a public sale or was less than the aggregate
amount of the Obligations, even if the Collateral Agent accepts the first offer received and does not offer the Collateral to more than
one offeree.


 






    D-12


     


    

 


Each Debtor further agrees to
do or cause to be done all such other acts and things as may be necessary to make such sale or sales of any portion or all of any such
Collateral valid and binding and in compliance with any and all applicable laws, regulations, orders, writs, injunctions, decrees or awards
of any and all courts, arbitrators or governmental instrumentalities, domestic or foreign, having jurisdiction over any such sale or sales,
all at such Debtor’s expense. Each Debtor further agrees that a breach of any of the covenants contained in this Section 4.7
will cause irreparable injury to the Secured Parties, that the Secured Parties have no adequate remedy at law in respect of such breach
and, as a consequence, agrees that each and every covenant contained in this Section 4.7 shall be specifically enforceable against
Debtors by Collateral Agent of behalf of each Secured Party, and each Debtor hereby waives and agrees not to assert any defenses against
an action for specific performance of such covenants except for a defense that no Event of Default has occurred and is continuing.


 


4.8 Application
of Proceeds. The proceeds of any collection, sale or other realization of all or any part of the Collateral, and any other cash at
the time held by the Collateral Agent under this Agreement, shall be applied to the Obligations in accordance with the Pro Rata Portion
of each Secured Party.


 


4.9 Attorney-in-Fact.
Each Debtor hereby irrevocably constitutes and appoints the Collateral Agent, with full power of substitution, as its true and lawful
attorney-in-fact with full irrevocable power and authority in the place and stead of such Debtor and in the name of such Debtor or in
its own name, from time to time in the discretion of the Collateral Agent, for the purpose of carrying out the terms of this Agreement,
to take any and all appropriate action and to execute and deliver any and all documents and instruments which may be necessary or desirable
to perfect or protect any security interest granted hereunder, to maintain the perfection or priority of any security interest granted
hereunder, or to otherwise accomplish the purposes of this Agreement, and, without limiting the generality of the foregoing, hereby gives
the Collateral Agent the power and right, on behalf of such Debtor, without notice to or assent by such Debtor (to the extent permitted
by applicable law), to do the following:


 


(a) to
take any and all appropriate action and to execute and deliver any and all documents and instruments which may be necessary or desirable
to accomplish the purposes of this Agreement;


 


(b) upon
the occurrence and during the continuation of an Event of Default, to ask, demand, collect, receive and give acquittance and receipts
for any and all moneys due and to become due under any Collateral and, in the name of such Debtor or its own name or otherwise, to take
possession of and endorse and collect any checks, drafts, notes, acceptances or other Instruments for the payment of moneys due under
any Collateral and to file any claim or to take any other action or proceeding in any court of law or equity or otherwise deemed appropriate
by the Collateral Agent for the purpose of collecting any and all such moneys due under any Collateral whenever payable and to file any
claim or to take any other action or proceeding in any court of law or equity or otherwise deemed appropriate by the Collateral Agent
for the purpose of collecting any and all such moneys due under any Collateral whenever payable;


 






    D-13


     


    

 


(c) to
pay or discharge charges or liens levied or placed on or threatened against the Collateral, to effect any insurance called for by the
terms of this Agreement and to pay all or any part of the premiums therefor;


 


(d) to
direct any party liable for any payment under any of the Collateral to make payment of any and all moneys due, and to become due thereunder,
directly to the Collateral Agent or as the Collateral Agent shall direct, and to receive payment of and receipt for any and all moneys,
claims and other amounts due, and to become due at any time, in respect of or arising out of any Collateral;


 


(e) upon
the occurrence and during the continuation of an Event of Default, to sign and indorse any invoices, freight or express bills, bills of
lading, storage or warehouse receipts, drafts against debtors, assignments, verifications and notices in connection with accounts and
other Documents constituting or relating to the Collateral;


 


(f) upon
the occurrence and during the continuation of an Event of Default, to commence and prosecute any suits, actions or proceedings at law
or in equity in any court of competent jurisdiction to collect the Collateral or any part thereof and to enforce any other right in respect
of any Collateral;


 


(g) upon
the occurrence and during the continuation of an Event of Default, to defend any suit, action or proceeding brought against a Debtor with
respect to any Collateral;


 


(h) upon
the occurrence and during the continuation of an Event of Default, to settle, compromise or adjust any suit, action or proceeding described
above and, in connection therewith, to give such discharges or releases as the Collateral Agent may deem appropriate;


 


(i) to
the extent that a Debtor’s authorization given in Section 4.1(b) of this Agreement is not sufficient to file such financing
statements with respect to this Agreement, with or without such Debtor’s signature, or to file a photocopy of this Agreement in
substitution for a financing statement, as the Collateral Agent may deem appropriate and to execute in such Debtor’s name such financing
statements and amendments thereto and continuation statements which may require such Debtor’s signature;


 


(j) upon
the occurrence and during the continuation of an Event of Default, generally to sell, transfer, pledge, make any agreement with respect
to or otherwise deal with any of the Collateral as fully and completely as though the Collateral Agent were the absolute owners thereof
for all purposes; and


 






    D-14


     


    

 


(k) to
do, at the Collateral Agent’s option and at such Debtor’s expense, at any time, or from time to time, all acts and things
which the Collateral Agent reasonably deems necessary to protect or preserve or, upon the occurrence and during the continuation of an
Event of Default, realize upon the Collateral and the Secured Parties’ Liens therein, in order to effect the intent of this Agreement,
all as fully and effectively as such Debtor might do.


 


Each Debtor hereby ratifies,
to the extent permitted by law, all that such attorneys lawfully do or cause to be done by virtue hereof provided the same is performed
in a commercially reasonable manner. The power of attorney granted hereunder is a power coupled with an interest and shall be irrevocable
until the Obligations are indefeasibly paid in full in cash and this Agreement is terminated in accordance with Section 4.11 hereof.


 


Each Debtor also authorizes
the Collateral Agent, at any time from and after the occurrence and during the continuation of any Event of Default, (1) to communicate
in its own name with any party to any Contract with regard to the assignment of the right, title and interest of such Debtor in and under
the Contracts hereunder and other matters relating thereto and (2) to execute, in connection with any sale of Collateral provided for
in Section 4.5 hereof, any endorsements, assignments or other instruments of conveyance or transfer with respect to the Collateral.


 


4.10 Perfection.
Prior to or concurrently with the execution and delivery of this Agreement, each Debtor shall:


 


(a) file
such financing statements, assignments for security and other documents in such offices as may be necessary or as the Collateral Agent
or the Representative may request to perfect the security interests granted by Section 3 of this Agreement; provided that
if the Debtor has not done so, the Collateral Agent may do so at any later time at the sole cost of the Debtors; and


 


(b) at
the Collateral Agent’s request, deliver to the Collateral Agent or its Representative the originals of all Instruments together
with, in the case of Instruments constituting promissory notes, allonges attached thereto showing such promissory notes to be payable
to the order of a blank payee.


 


4.11 Termination;
Partial Release of Collateral. This Agreement and the Liens and security interests granted hereunder shall not terminate until the
full and complete performance and indefeasible satisfaction (including, to the extent applicable, through the conversion in full into
Common Stock of any outstanding Secured Advance) of all of the Obligations (i) under the Secured Advances (including, without limitation,
the indefeasible payment in full in cash or the conversion in full into Common Stock of all of the Obligations under the outstanding Secured
Advances), and/or (ii) that have arisen under the Security Purchase Contract and remain outstanding on or prior to the payment or other
satisfaction of the Obligations under any outstanding Secured Advance ((i) and (ii) being, collectively, the “Advance Payment
Obligations”), whereupon the Collateral Agent shall forthwith cause to be assigned, transferred and delivered, against receipt
but without any recourse, warranty or representation whatsoever, any remaining Collateral to or on the order of Debtors. The Collateral
Agent shall also execute and deliver to Debtors upon such termination and at Debtors’ expense such UCC termination statements, certificates
for terminating the liens on the Motor Vehicles (if any) and such other documentation as shall be reasonably requested by Debtors or otherwise
necessary to effect the termination and release of all Liens and security interests in favor of the Collateral Agent affecting the Collateral.
Notwithstanding anything to the contrary in this Agreement, upon full and complete satisfaction of the Advance Payment Obligations, each
Debtor’s obligations under this Agreement shall immediately terminate and any Liens shall thereupon be void.


 






    D-15


     


    

 


4.12 Further
Assurances. At any time and from time to time, upon the written request of the Collateral Agent or its Representative, and at the
sole expense of Debtors, Debtors will promptly and duly execute and deliver any and all such further instruments, documents and agreements
and take such further actions as the Collateral Agent or its Representative may reasonably require in order for the Collateral Agent to
obtain the full benefits of this Agreement and of the rights and powers herein granted in favor of the Collateral Agent, including, without
limitation, using Debtors’ best efforts to secure all consents and approvals necessary or appropriate for the assignment to the
Collateral Agent of any Collateral held by Debtors or in which a Debtor has any rights not heretofore assigned, the filing of any financing
or continuation statements under the UCC with respect to the liens and security interests granted hereby, transferring Collateral to the
Collateral Agent’s possession (if a security interest in such Collateral can be perfected by possession), placing the interest of
the Collateral Agent as lienholder on the certificate of title of any Motor Vehicle, and obtaining waivers of liens from landlords and
mortgagees. Each Debtor also hereby authorizes the Collateral Agent and its Representative to file any such financing or continuation
statement without the signature of such Debtor to the extent permitted by applicable law.


 


4.13 Limitation
on Duty of Secured Party. The powers conferred on the Collateral Agent under this Agreement are solely to protect the Collateral Agent’s
interest on behalf of itself and the other Secured Parties in the Collateral and shall not impose any duty upon it to exercise any such
powers. The Collateral Agent shall be accountable only for amounts that it actually receives as a result of the exercise of such powers
and neither the Collateral Agent nor its Representative nor any of their respective officers, directors, employees or agents shall be
responsible to Debtors for any act or failure to act, except for gross negligence or willful misconduct. Without limiting the foregoing,
the Collateral Agent and any Representative shall be deemed to have exercised reasonable care in the custody and preservation of the Collateral
in their possession if such Collateral is accorded treatment substantially equivalent to that which the Collateral Agent or any Representative,
in its individual capacity, accords its own property consisting of the type of Collateral involved, it being understood and agreed that
neither the Collateral Agent nor any Representative shall have any responsibility for taking any necessary steps (other than steps taken
in accordance with the standard of care set forth above) to preserve rights against any Person with respect to any Collateral.


 


Also without limiting the
generality of the foregoing, neither the Collateral Agent nor any Representative shall have any obligation or liability under any Contract
or license by reason of or arising out of this Agreement or the granting to the Collateral Agent of a security interest therein or assignment
thereof or the receipt by the Collateral Agent or any Representative of any payment relating to any Contract or license pursuant hereto,
nor shall the Collateral Agent or any Representative be required or obligated in any manner to perform or fulfill any of the obligations
of Debtors under or pursuant to any Contract or license, or to make any payment, or to make any inquiry as to the nature or the sufficiency
of any payment received by it or the sufficiency of any performance by any party under any Contract or license, or to present or file
any claim, or to take any action to collect or enforce any performance or the payment of any amounts which may have been assigned to it
or to which it may be entitled at any time or times.

Section 5. Miscellaneous.


 


5.1 No
Waiver. No failure on the part of the Collateral Agent or any of its Representatives to exercise, and no course of dealing with respect
to, and no delay in exercising, any right, power or remedy hereunder shall operate as a waiver thereof, nor shall any single or partial
exercise by the Collateral Agent or any of its Representatives of any right, power or remedy hereunder preclude any other or further exercise
thereof or the exercise of any other right, power or remedy. The rights and remedies hereunder provided are cumulative and may be exercised
singly or concurrently, and are not exclusive of any rights and remedies provided by law.


 


5.2 Governing
Law. All questions concerning the construction, validity, enforcement and interpretation of this Security Agreement shall be governed

of each Secured Party. Any Secured Party, including the Collateral Agent in its capacity as a Secured Party, may assign its rights hereunder
without the consent of Debtors, in which event such assignee shall be deemed to be a Secured Party and/or Collateral Agent, as applicable,
hereunder with respect to such assigned rights.


 


5.6 Counterparts;

the same instrument and any of the parties hereto may authenticate this Agreement by signing any such counterpart. This Agreement may

Agent, its Representative and each other Secured Party (and all of their respective successors and assigns) in order to carry out the
intentions of the parties hereto as nearly as may be possible and (b) the invalidity or unenforceability of any provision hereof in any
jurisdiction shall not affect the validity or enforceability of such provision in any other jurisdiction.


 






    D-17


     


    

 


5.8 Exclusive
Jurisdiction. Any action, proceeding or claim arising out of, or relating in any way to, this Agreement shall be brought and enforced
only as provided in the Security Purchase Contract.


 


5.9 Waiver

of action based upon or arising out of or related to this Agreement or the transactions contemplated hereby, in any action, proceeding
or other litigation of any type brought by any of the parties against any other party or parties, whether with respect to contract claims,
tort claims, or otherwise. Each Debtor and each Secured Party agree that any such claim or cause of action shall be tried by a court trial
without a jury. Without limiting the foregoing, the parties further agree that their respective right to a trial by jury is waived by
operation of this Section 5.9 as to any action, counterclaim or other proceeding which seeks, in whole or in part, to challenge the validity
or enforceability of this agreement or any provision hereof. This waiver shall apply to any subsequent amendments, renewals, supplements
or modifications to this Agreement.


 


5.10 Joint

(a) Each
Secured Party has, pursuant to the Security Purchase Contract, designated and appointed the Collateral Agent as the administrative agent
of such Secured Party under this Agreement and the related agreements.


 


(b) Nothing
in this Section 5.11 shall be deemed to limit or otherwise affect the rights of the Collateral Agent to exercise any remedy provided
in this Agreement or any other Transaction Document.


 


(c) If
pursuant to any Transaction Document a Secured Party (including the Collateral Agent) is given the discretion to allocate proceeds received
by such Secured Party (including the Collateral Agent) pursuant to the exercise of remedies under the Transaction Documents or at law
or in equity (including without limitation with respect to any secured creditor remedies exercised against the Collateral and any other
collateral security provided for under any Transaction Document), the Collateral Agent shall apply such proceeds to the then outstanding
Obligations in the following order of priority (with amounts received being applied in the numerical order set forth below until exhausted
prior to the application to the next succeeding category and each Secured Party entitled to payment shall receive an amount equal to its
Pro Rata Portion of amounts available to be applied pursuant to clauses second, third and fourth below):


 


first, to
payment of fees, costs and expenses (including reasonable attorney’s fees) owing to the Collateral Agent;


 






    D-18


     


    

 


second, to
payment of all accrued unpaid interest and fees (other than fees owing to Collateral Agent) on the Obligations;


 


third, to
payment of principal of the Obligations;


 


fourth, to
payment of any other amounts owing constituting Obligations; and


 


fifth, any
remainder shall be for the account of and paid to whoever may be lawfully entitled thereto.


 


(d) Each
Debtor agrees, jointly and severally, to indemnify, defend and hold harmless the Collateral Agent (both in its capacity as collateral
agent hereunder and as a Secured Party), every other Secured Party, their respective successors and assigns and all of their respective
officers, directors, shareholders, members, managers, partners, employees, attorneys and agents, and any Person in control of any thereof,
from and against any claims, debts, liabilities, losses, demands, obligations, actions, causes of action, fines, penalties, costs and
expenses (including attorneys’ fees and consultants’ fees), of every nature, character and description (each, an “Indemnified
Liability” and collectively the “Indemnified Liabilities”), under federal and state securities laws or otherwise
insofar as such Indemnified Liability arises out of or is based upon any of the transactions contemplated by this Agreement, any other
Transaction Document, any of the Obligations, or any other cause or thing whatsoever occurred, done, omitted or suffered to be done by
a Debtor relating to any Secured Party or the Obligations (except any such amounts sustained or incurred solely as the result of the gross
negligence or willful misconduct of such Secured Party(ies), as finally determined by a court of competent jurisdiction). If and to the
extent that the foregoing undertakings in this paragraph may be unenforceable for any reason, each Debtor agrees to jointly and severally
make the maximum contribution to the payment and satisfaction of each of the Indemnified Liabilities which is permissible under applicable
law. The obligations of each Debtor under this Section 5.11(d) shall survive any termination of this Agreement or any other Transaction
Document.


 


5.12 No
Strict 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.


 


5.13 Entire
Agreement; Amendment. This Agreement, together with the other transaction documents, supersedes all other prior oral or written agreements
between the Secured Parties, the Collateral Agent, the Debtors, their affiliates and persons acting on their behalf with respect to the
matters discussed herein, and this Agreement, together with the other transaction documents and the other instruments referenced herein
and therein, contain the entire understanding of the parties with respect to the matters covered herein and therein and, except as specifically
set forth herein or therein, neither the secured party nor any Debtor makes any representation, warranty, covenant or undertaking with
respect to such matters. As of the date of this Agreement, there are no unwritten agreements between the parties with respect to the matters
discussed herein. No provision of this Agreement may be amended, modified or supplemented other than by an instrument in writing signed
by the Debtors and the Secured Party.

SUBSIDIARY GUARANTEE


 


This SUBSIDIARY GUARANTEE
(as amended, restated, supplemented, or otherwise modified and in effect from time to time, this “Guarantee”) is made as of
[______], jointly and severally, between Ascent Solar Technologies, Inc., a Delaware corporation (the “Company”), and together
with each other Person who becomes a party to this Guarantee by execution of a joinder in the form of Exhibit A attached hereto,
which shall include all wholly-owned or majority-owned subsidiaries of the Company acquired after the date hereof for so long as this
Guarantee remains in effect (except as otherweise provided in the Securities Purchase Contract by and among the Company and the Purchasers
as defined therein dated the date of this Guarantee (the “Purchase Agreement”), shall each be referred to individually as
a “Guarantor” and collectively as the “Guarantors”), in favor of the Purchasers and the Collateral Agent as defined
in the Purchase Agreement. All references to a “Purchaser” or “Purchasers” hereunder shall include the Collateral
Agent acting in its capacity as a Purchaser.


 


WHEREAS, pursuant to and in
accordance with the Purchase Agreement, the Company has executed and delivered those certain Advance Notes as defined in the Purchase
Agreement dated as of December 19, 2022 (the “Closing Date”) in an original aggregate principal amount of $15,000,000 as provided
in the Purchase Agreement all of which shall be issued at the Closing Date. As used in this Agreement, the phrase Advance Notes also includes
the Prepaid-Tranches; 


 


WHEREAS, pursuant to a Pledge
Agreement, dated as of the date hereof (as the same may be amended, restated, supplemented or otherwise modified from time to time, the
“Pledge Agreement”), the Company has granted to the Collateral Agent for the benefit of the Purchasers a Lien on and security
interest in all of the issued and outstanding equity interests of the Pledged Entities (as defined in the Pledge Agreement);


 


WHEREAS, pursuant to a Security
Agreement, dated as of the Closing Date (as the same may be amended, restated, supplemented or otherwise modified and in effect from time
to time, the “Security Agreement”) by the Debtors (as defined in the Security Agreement) in favor of the Collateral Agent,
such Debtors have granted the Collateral Agent, for its benefit and the benefit of the other Purchasers, a first priority Lien on and
security interest in all of their respective rights in the Collateral (as defined in the Security Agreement); and


 


WHEREAS, the Guarantors will
be subsidiaries of the Company and, as such, will derive substantial benefit and advantage from the Purchase Agreement, the Advance Notes,
the Pledge Agreement, the Security Agreement and the other related agreements (collectively, the “Transaction Documents”).


 


NOW, THEREFORE, for and in
consideration of the promises and for other good and valuable consideration, the receipt and sufficiency of which are hereby acknowledged,
each Guarantor hereby jointly and severally agrees as follows:


 


1. Definitions:
Capitalized words and terms used herein without definition and defined in the Purchase Agreement are used herein as defined therein. In
addition, as used herein:


 


“Bankruptcy Code”
shall mean the Federal Bankruptcy Reform Act of 1978 (11 U.S.C. §101, et seq.), as amended and in effect from time to time
thereunder.


 


“Obligations” shall
have the meaning set forth in the Security Agreement.


 






    E-1


     


    

 


2. Guarantee
of Payment.


 


(a) Each
Guarantor, jointly and severally, hereby unconditionally and irrevocably guarantees the full and prompt payment and performance to the
Purchasers and the Collateral Agent, on behalf of itself and in its capacity as agent for the benefit of Purchasers, when due, upon demand,
at maturity or by reason of acceleration or otherwise and at all times thereafter, of any and all of the Obligations.


 


(b) Each
Guarantor acknowledges that valuable consideration supports this Guarantee, including, without limitation, the consideration set forth
in the recitals above; any extension, renewal or replacement of any of the Obligations; any forbearance with respect to any of the Obligations
or otherwise; any cancellation of an existing guaranty; any purchase of any of the Company’s assets by any Purchaser or Collateral
Agent; or any other valuable consideration.


 


(c) Each
Guarantor agrees that all payments under this Guarantee shall be made in United States currency and in the same manner as provided for
the Obligations.


 


(d) Notwithstanding
any provision of this Guarantee to the contrary, it is intended that this Guarantee, and any interests, Liens and security interests granted
by Guarantors as security for this Guarantee, not constitute a “Fraudulent Conveyance” (as defined below) in the event that
this Guarantee or such interest is subject to the Bankruptcy Code or any applicable fraudulent conveyance or fraudulent transfer law or
other applicable laws of any state. Consequently, the Guarantors, the Collateral Agent and the Purchasers all agree that if this Guarantee,
or any such interests, Liens or security interests securing this Guarantee, would, but for the application of this sentence, constitute
a fraudulent conveyance, this Guarantee and each such Lien and security interest shall be valid and enforceable only to the maximum extent
that would not cause this Guarantee or such interest, Lien or security interest to constitute a Fraudulent Conveyance, and this Guarantee
shall automatically be deemed to have been amended accordingly at all relevant times. For purposes hereof, “Fraudulent Conveyance”
means a fraudulent conveyance under Section 548 of the Bankruptcy Code or a fraudulent conveyance or fraudulent transfer under the provisions
of any applicable fraudulent conveyance or fraudulent transfer law or other applicable laws of any state, as in effect from time to time.


 


3. Costs
and Expenses. The Company and each Guarantor, jointly and severally, agrees to pay on demand, all reasonable Costs and Expenses of
every kind incurred by any Purchaser or the Collateral Agent: (a) in enforcing this Guarantee or any other Transaction Document, (b) in
collecting any of the Obligations from any Guarantor pursuant to this Guarantee or any other Transaction Document, (c) in realizing upon
or protecting or preserving any Collateral (as defined in the Security Agreement), and (d) in connection with any amendment of, modification
to, waiver or forbearance granted under, or enforcement or administration of this Guarantee or any other Transaction Document or for any
other purpose in connection with this Guarantee or any other Transaction Document, in each case, to the extent a Purchaser or the Collateral
Agent may take such action pursuant to the terms and conditions of this Guarantee. “Costs and Expenses” as used in the preceding
sentence shall include, without limitation, reasonable attorneys’ fees incurred by any Purchaser or the Collateral Agent in retaining
legal counsel for advice, suit, appeal, any insolvency or other proceedings under the Bankruptcy Code or otherwise, or for any purpose
specified in the preceding sentence.


 






    E-2


     


    

 


4. Nature
of Guarantee: Continuing, Absolute and Unconditional.


 


(a) This
Guarantee is and is intended to be a continuing guaranty of payment of the Obligations, and not of collectability, and is intended to
be independent of and in addition to any other guaranty, endorsement, collateral or other agreement held by a Purchaser or the Collateral
Agent therefor or with respect thereto, whether or not furnished by a Guarantor. None of Purchasers and Agent shall be required to prosecute
collection, enforcement or other remedies against any Company, any other Guarantor or guarantor of the Obligations or any other person
or entity, or to enforce or resort to any of the Collateral or other rights or remedies pertaining thereto, before calling on a Guarantor
for payment. The obligations of each Guarantor to repay the Obligations hereunder shall be unconditional. Guarantor shall have no right
to exercise any right of subrogation, reimbursement, indemnity, exoneration, contribution or any other claim which it may now or hereafter
have against any Company in connection with this Guarantee until the termination of this Guarantee in accordance with Section 8 below,
and hereby waives any benefit of, and any right to participate in, any security or collateral given to Purchasers to secure payment of
the Obligations, and each Guarantor agrees that it will not take any action to enforce any obligations of any Company to such Guarantor
prior to the Obligations being finally and irrevocably paid in full in cash, provided that, in the event of the bankruptcy or insolvency
of any Company, to the extent the Obligations have not been finally and irrevocably paid in full in cash, Agent, for the benefit of itself
and Purchasers, and Purchasers shall be entitled notwithstanding the foregoing, to file in the name of any Guarantor or in its own name
a claim for any and all indebtedness owing to a Guarantor by such Company (exclusive of this Guarantee), vote such claim and to apply
the proceeds of any such claim to the Obligations.


 


(b) For
the further security of Purchasers and without in any way diminishing the liability of the Guarantors, following the occurrence and during
the continuance of an Event of Default, all debts and liabilities, present or future, of the Company to the Guarantors, and all monies
received from any Company or for its account by the Guarantors in respect thereof shall be received in trust for the Purchasers and the
Collateral Agent and promptly following receipt shall be paid over to the Collateral Agent, for its benefit and in its capacity as Agent
for the benefit of Purchasers, until all of the Obligations have been paid in full in cash. This assignment and postponement is independent
of and severable from this Guarantee and shall remain in full effect whether or not any Guarantor is liable for any amount under this
Guarantee.


 


(c) This
Guarantee is absolute and unconditional and shall not be changed or affected by any representation, oral agreement, act or thing whatsoever,
except as herein provided. This Guarantee is intended by the Guarantors to be the final, complete and exclusive expression of the guarantee
agreement among the Company, the Guarantors, the Purchasers and the Collateral Agent (except as expressly limited by the express terms
of this Guarantee). No modification or amendment of any provision of this Guarantee shall be effective against any party hereto unless
in writing and signed by a duly authorized officer of such party. This Guarantee, together with the other Transaction Documents, supersedes
all other prior oral or written agreements between the Purchasers, the Company, the Guarantors and the Collateral Agent, their respective
Affiliates and Persons acting on their respective behalves with respect to the matters discussed herein, and this Guarantee, together
with the other Transaction Documents and the other instruments referenced herein and therein, contain the entire understanding of the
parties with respect to the matters covered herein and therein and, except as specifically set forth herein or therein, neither the Company,
any Guarantor, the Collateral Agent nor any Purchaser makes any representation, warranty, covenant or undertaking with respect to such
matters. As of the date of this Guarantee, there are no unwritten agreements between the parties with respect to the matters discussed
herein. No provision of this Guarantee may be amended, modified or supplemented other than by an instrument in writing signed by the parties
hereto.

Guarantor hereby releases each Purchaser and the Collateral Agent from all, and agrees not to assert or enforce (whether by or in a legal
or equitable proceeding or otherwise) any, “claims” (as defined in Section 101(5) of the Bankruptcy Code), whether arising
under any law, ordinance, rule, regulation, order, policy or other requirement of any domestic or foreign governmental authority or any
instrumentality or agency thereof, having jurisdiction over the conduct of its business or assets or otherwise, to which the Guarantors
are or would at any time be entitled by virtue of its obligations hereunder, any payment made pursuant hereto or the exercise by any Purchaser
or the Collateral Agent of its rights with respect to the Collateral (as defined in the Security Agreement), including any such claims
to which such Guarantor may be entitled as a result of any right of subrogation, exoneration or reimbursement.

either in whole or in part for any act or omission in connection with a Purchaser or Collateral Agent having sold any security at less

demand for payment or proof of such demand or filing of claims with a court in the event of receivership, bankruptcy or reorganization
of the Company or any other Guarantor;


 


(iv) without
requiring any Purchaser or the Collateral Agent to resort first to the Company (this being a guaranty of payment and not of collection),
to any other Guarantor, or to any other guaranty or any collateral which a Purchaser or the Collateral Agent may hold;


 


(v) without
requiring notice of acceptance hereof or assent hereto by any Purchaser or the Collateral Agent; and

(ix) any
change in, or the imposition of, any law, decree, regulation or other governmental act which does or might impair, delay or in any way

(x) the
existence of any claim, setoff or other rights which the Company, the Guarantor, any other Guarantor or guarantor of the Obligations or
any other Person may have at any time against any Purchaser or the Collateral Agent in connection herewith or any unrelated transaction;

(xii) the
disallowance of all or any portion of any of any Purchaser’s or the Collateral Agent’s claims for repayment of the Obligations

(xiii) any
stay or extension of time for payment by the Company or any Guarantor resulting from any proceeding under the Bankruptcy Code or any other
applicable law; or


 


(xiv) any
other fact or circumstance which might otherwise constitute grounds at law or equity for the discharge or release of a Guarantor from
its obligations hereunder, all whether or not such Guarantor shall have had notice or knowledge of any act or omission referred to in
the foregoing clauses (i) through (xiv) of this Section 5(c).


 


6. Representations
and Warranties. Each Guarantor further represents and warrants to each Purchaser and the Collateral Agent that: (a) such Guarantor
is a corporation or other entity duly incorporated or organized, as applicable, validly existing and in good standing under the laws of
the jurisdiction of its incorporation or formation, as applicable, and has full power, authority and legal right to own its property and
assets and to transact the business in which it is presently engaged; (b) such Guarantor has full power, authority and legal right to
execute and deliver, and to perform its obligations under, this Guarantee, and has taken all necessary action to authorize the guarantee
hereunder on the terms and conditions of this Guarantee and to authorize the execution, delivery and performance of this Guarantee; (c)
this Guarantee has been duly executed and delivered by such Guarantor and constitutes a legal, valid and binding obligation of such Guarantor
enforceable against such Guarantor in accordance with its terms, except to the extent that such enforceability is subject to applicable
bankruptcy, insolvency, reorganization, fraudulent conveyance and moratorium laws and other laws of general application affecting enforcement
of creditors’ rights generally, or the availability of equitable remedies, which are subject to the discretion of the court before
which an action may be brought; (d) the execution, delivery and performance by each Guarantor of this Guarantee does not require any action
by or in respect of, or filing with, any governmental body, agency or official and do not violate, conflict with or cause a breach or

injunction, order, decree or other instrument binding upon it, or (iv) any agreement binding upon it; and (e) the Guarantors are all of
the subsidiaries of the Company with the exception of a construction subsidiary which the Purchasers acknowledge does not have to guarantee
payment or be a party to this Subsidiary Guarantee.


 


7. Covenants.
Each Guarantor covenants with each Purchaser and the Collateral Agent that such Guarantor shall not grant any security interest in or
permit any Lien upon any of its assets in favor of any Person other than Permitted Liens (as defined in the Advance Notes) and security
interests in favor of the Purchasers and the Collateral Agent. Each Guarantor agrees that it shall not take any action or engage in any
transaction that such Guarantor is prohibited from taking or engaging in pursuant to the terms of the Transaction Documents. In addition,
each Guarantor agrees to comply with the terms of the Transaction Documents to the same extent that the Company is required to cause the
Guarantors to comply with such terms of the Transaction Documents. Each Guarantor, by its signature hereto, hereby acknowledges and agrees
that a breach by such Guarantor of this Agreement constitutes an “Event of Default” under the Advance Notes and the other
Transaction Documents.


 






    E-7


     


    

 


8. Termination.
This Guarantee shall not terminate until the full and complete performance and indefeasible satisfaction of all of the Obligations (including,
without limitation, the indefeasible payment in full in cash of all such Obligations) (i) in respect of the Transaction Documents, and
(ii) with respect to which claims have been asserted by Collateral Agent and/or a Purchaser arising out of or relating to the Transaction
Documents. Thereafter, but subject to the following, the Collateral Agent, on behalf of itself and as agent for the Purchasers, shall
take such actions and execute such documents as the Guarantors may reasonably request (and at the Guarantors’ cost and expense)
in order to evidence the termination of this Guarantee. Payment of all of the Obligations owing from time to time shall not operate as
a discontinuance of this Guarantee. Each Guarantor further agrees that, to the extent that the Company or a Guarantor makes a payment
to the Purchasers or the Collateral Agent on the Obligations, or the Purchasers or the Collateral Agent receive any proceeds from the
Collateral (as defined in the Security Agreement) securing the Obligations or any other payments with respect to the Obligations, which
payment or receipt of proceeds or any part thereof is subsequently invalidated, declared to be fraudulent or preferential, set aside or
required to be returned or repaid to the Company, a Guarantor or any of their respective estates, trustees, receivers, debtors in possession
or any other Person under any insolvency or bankruptcy law (including, but not limited to the Bankruptcy Code), state or federal law,
common law or equitable cause, then to the extent of such payment, return or repayment, the obligation or part thereof which has been
paid, reduced or satisfied by such amount shall be reinstated and continued in full force and effect as of the date when such initial
payment, reduction or satisfaction occurred, and this Guarantee shall continue in full force notwithstanding any contrary action which
may have been taken by any Purchaser or the Collateral Agent in reliance upon such payment, and any such contrary action so taken shall
be without prejudice to any Purchaser’s or the Collateral Agent’s rights under this Guarantee and shall be deemed to have
been conditioned upon such payment having become final and irrevocable. Upon satisfaction of the Obligations in accordance with this Section
8, the Guarantors’ obligations under this Agreement shall immediately terminate and the Guarantee shall be void.


 


9. Guarantee
of Performance. Each Guarantor also, jointly and severally, guarantees the full, prompt and unconditional performance of all Obligations
and agreements of every kind owed or hereafter to be owed by the Company or the other Guarantors to the Purchasers or the Collateral Agent
under this Guarantee and the other Transaction Documents. Every provision for the benefit of the Purchasers or the Collateral Agent contained
in this Guarantee shall apply to the guaranty of performance given in this Section 9.


 


10. Assumption
of Liens and Obligations. To the extent that a Guarantor has received or shall hereafter receive distributions or transfers from the
Company of property or cash that are subject, at the time of such distribution or transfer, to Liens and security interests in favor of
Purchasers or the Collateral Agent in accordance with the Transaction Documents, such Guarantor hereby expressly agrees that (i) it shall
hold such assets subject to such Liens and security interests, and (ii) it shall be liable for the payment of the Obligations secured
thereby. Each Guarantor’s obligations under this Section 10 shall be in addition to its obligations as set forth in other sections
of this Guarantee and not in substitution therefor or in lieu thereof.

11. Miscellaneous.


 


(a) The

any Affiliate of any Purchaser or the Collateral Agent, whether for deposit or otherwise;


 


in each case, whether or not then due and owing,
and the applicable Purchaser or the Collateral Agent, as applicable, shall be deemed to have exercised such right of set off immediately
at the time of such election even though any charge therefore is made or entered on such Purchaser’s or the Collateral Agent’s
records subsequent thereto. The Collateral Agent agrees to notify such Guarantor in a reasonable time of any such set-off; however, failure
of the Collateral Agent to so notify such Guarantor shall not affect the validity of any set-off.


 


(c) Each
Guarantor’s obligation hereunder is to pay the Obligations in full in cash when due according to this Guarantee, the Advance Notes,
the Warrants, the other Transaction Documents, and any other agreements, documents and instruments governing the Obligations to the extent
provided herein, and shall not be affected by any stay or extension of time for payment for the benefit of the Company or any other Guarantor
resulting from any proceeding under the Bankruptcy Code or any other applicable law.


 


(d) No
course of dealing between the Company or any Guarantor, on the one hand, and a Purchaser or the Collateral Agent, on the other hand, and
no act, delay or omission by a Purchasers or the Collateral Agent in exercising any right or remedy hereunder or with respect to any of
the Obligations shall operate as a waiver thereof or of any other right or remedy, and no single or partial exercise thereof shall preclude
any other or further exercise thereof or the exercise of any other right or remedy. The rights and remedies of each Purchaser and the
Collateral Agent hereunder are cumulative and may be exercised singly or concurrently, and are not exclusive of any rights and remedies
provided by law.


 






    E-9


     


    

 


(e) This
Guarantee shall inure to the benefit of the parties hereto and their respective successors and assigns.


 


(f) Collateral
Agent may assign its rights hereunder, in which event such assignee shall be deemed to be the Collateral Agent hereunder with respect
to such assigned rights.

(i) All
questions concerning the construction, validity, enforcement and interpretation of this Guaranty shall be governed by the Purchase Agreement.
Any action, proceeding or claim arising out of, or relating in any way to, this Agreement shall be brought and enforced only as provided
in the Purchase Agreement.


 


12. Notices.
All notices, approvals, requests, demands and other communications hereunder shall be delivered or made in the manner set forth in, and

13. Waivers.

Guarantor waives the benefit of all valuation, appraisal and exemption laws.


 


(b) Upon
the occurrence of a default or Event of Default (as defined in the Advance Notes), each Guarantor hereby waives all rights to notice and

benefit of Purchasers, of its rights to repossess the Collateral without judicial process or to replevy, attach or levy upon the Collateral
without prior notice or hearing. Each Guarantor acknowledges that it has been advised by counsel of its choice with respect to this transaction
and this Guarantee.


 


(c) Each
Guarantor waives its rights to a trial by jury of any claim or cause of action based upon or arising out of or related to this guaranty,
or the other transaction documents, in any action, proceeding or other litigation of any type brought by any Purchaser or the Collateral
Agent. Each Guarantor agrees that any such claim or cause of action shall be tried by a court without a jury. Without limiting the foregoing,
each guarantor further agrees that its right to a trial by jury is waived by operation of this section as to any action, counterclaim
or other proceeding which seeks, in whole or in part, to challenge the validity or enforceability of this Guarantee or any provision hereof.
This waiver shall apply to any subsequent amendments, renewals, supplements or modifications to this Guarantee.

15. Payments

organized or in which its principal office is located.


 


(ii) “Governmental
Authority” means the government of the United States of America or any other nation, or any political subdivision thereof, whether
state or local, or any agency, authority, instrumentality, regulatory body, court, central bank or other entity exercising executive,
legislative, judicial, taxing, regulatory or administrative powers or functions of or pertaining to government over the company or any
of the Guarantors, or any of their respective properties, assets or undertakings.


 


(iii) “Indemnified
Taxes” means Taxes other than Excluded Taxes.


 


(iv) “Taxes”
means any and all present or future taxes, levies, imposts, duties, deductions, charges or withholdings imposed by any Governmental Authority.


 


(b) Any
and all payments by or on account of the Obligations of any of the Guarantors under this Guarantee or any other Transaction Document shall
be made without any set-off, counterclaim or deduction and free and clear of and without deduction for any Indemnified Taxes; provided
that if any Guarantor shall be required to deduct any Indemnified Taxes from such payments, then (i) the sum payable shall be increased
as necessary so that after making all required deductions (including deductions applicable to additional sums payable under this Section
15(b)), the Collateral Agent or the Purchasers, as applicable, receives an amount equal to the sum it would have received had no such
deductions been made, (ii) such Guarantor shall make such deductions and (iii) such Guarantor shall pay the full amount deducted to the
relevant Governmental Authority in accordance with applicable law.


 


16. Indemnification
by the Guarantors. Each Guarantor shall indemnify the Collateral Agent and the Purchasers, within10 days after written demand therefor,

or imposed or asserted on or attributable to amounts payable under this Section 16) and any penalties, interest and reasonable expenses
including reasonable attorneys’ fees arising therefrom or with respect thereto, whether or not such Indemnified Taxes were correctly
or legally imposed or asserted by the relevant Governmental Authority. A certificate of the Collateral Agent or any Purchaser as to the
amount of such payment or liability under this Section 16 shall be delivered to such Guarantor and shall be conclusive absent manifest
error.


 






    E-11


     


    

 


17. Counterparts;
Headings. This Guarantee may be executed in two or more identical counterparts, all of which together shall be considered one and
the same agreement and shall become effective when counterparts have been signed by each party and delivered to each other party; provided
that a facsimile, .pdf or similar electronically transmitted signature shall be considered due execution and shall be binding upon the
signatory thereto with the same force and effect as if the signature were an original signature. The headings in this Guarantee are for
convenience of reference only and shall not alter or otherwise affect the meaning hereof.


 


18. Rights
of Contribution. The Guarantors hereby agree as among themselves that, if any Guarantor shall make an Excess Payment (as defined below),
such Guarantor shall have a right of contribution from each other Guarantor in an amount equal to such other Guarantor’s Contribution
Share (as defined below) of such Excess Payment. The payment obligations of any Guarantor under this Section 18 shall be subordinate and
subject in right of payment to the Obligations until such time as the Obligations have been paid in full in cash, and none of the Guarantors
shall exercise any right or remedy under this Section 18 against any other Guarantor until such Obligations have been paid in full in
cash. For purposes of this Section 18, (a) “Excess Payment” shall mean the amount paid by any Guarantor in excess of its Ratable
Share of any Obligations; (b) “Ratable Share” shall mean, for any Guarantor in respect of any payment of Obligations, the
ratio (expressed as a percentage) as of the date of such payment of Obligations of (i) the amount by which the aggregate present fair
salable value of all of its assets and properties exceeds the amount of all debts and liabilities of such Guarantor (including contingent,
subordinated, unmatured, and unliquidated liabilities, but excluding the obligations of such Guarantor hereunder) to (ii) the amount by
which the aggregate present fair salable value of all assets and other properties of the Company and the Guarantors exceeds the amount
of all of the debts and liabilities (including contingent, subordinated, unmatured, and unliquidated liabilities, but excluding the obligations
of the Guarantors hereunder) of the Company and the Guarantors, provided, that, for purposes of calculating the Ratable Shares
of the Guarantors in respect of any payment of Obligations, any Guarantor that became a Guarantor subsequent to the date of any such payment
shall be deemed to have been a Guarantor on the date of such payment and the financial information for such Guarantor as of the date such
Guarantor became a Guarantor shall be utilized for such Guarantor in connection with such payment; and (c) “Contribution Share”
shall mean, for any Guarantor in respect of any Excess Payment made by any other Guarantor, the ratio (expressed as a percentage) as of
the date of such Excess Payment of (i) the amount by which the aggregate present fair salable value of all of its assets and properties
exceeds the amount of all debts and liabilities of such Guarantor (including contingent, subordinated, unmatured, and unliquidated liabilities,
but excluding the Obligations) of the Company and the Guarantors other than the maker of such Excess Payment; provided, however,
that, for purposes of calculating the Contribution Shares of the Guarantors in respect of any Excess Payment, any Guarantor that became
a Guarantor subsequent to the date of any such Excess Payment shall be deemed to have been a Guarantor on the date of such Excess Payment
and the financial information for such Guarantor as of the date such Guarantor became a Guarantor shall be utilized for such Guarantor
in connection with such Excess Payment. This Section 18 shall not be deemed to affect any right of subrogation, indemnity, reimbursement
or contribution that any Guarantor may have under law against the Company in respect of any payment of Obligations.

EXHIBIT F


 


PLEDGE AGREEMENT


 


A.   THIS
PLEDGE AGREEMENT made as of December __, 2022 (as amended, restated, supplemented or otherwise modified from time to time, this “Agreement”),
by Ascent Solar Technologies, Inc., a Delaware corporation (the “Pledgor”) and the Collateral Agent, for itself as a Purchaser
and the other Purchasers identified below (together with their respective successors and assigns). As used in this Pledge Agreement, the
terms Collateral Agent and Purchasers each has the meaning contained in that certain Securities Purchase Contract dated as the date hereof
(as the same may be amended, restated, supplemented or otherwise modified, the “Purchase Agreement”), by and among the Pledgor
and the Purchasers.


 


WHEREAS:


 


B.   The
Pledgor has executed and delivered to the purchasers identified in that certain Purchase Agreement (as defined below) (and together with
their successors and assigns and each other purchaser of an Advance Note (as defined below) and their respective successors and assigns,
individually a “Purchaser” and collectively, the “Purchasers”) those certain senior secured convertible original
issue 10% discount advance each made by the Company and dated as of the date hereof in an original aggregate principal amount of up to
$50,000,000 as provided in the Purchase Agreement (such advance notes, together with any promissory notes or other securities issued in
exchange or substitution therefor or replacement thereof, and as any of the same may be amended, supplemented, restated or modified and
in effect from time to time, the “Advance Notes”). As used in this Pledge Agreement the term Advance Notes also includes the
Prepad-Tranches as defined in the Purchase Agreement. The Advance Notes were issued pursuant to that certain Securities Purchase Agreement
dated as the date hereof (as the same may be amended, restated, supplemented or otherwise modified, the “Purchase Agreement”),
by and among the Pledgor and the Purchasers.


 


C.   The
Pledgor legally and beneficially owns the interests specified on Exhibit A hereto and each other corporation or other entity, the
stock or other equity interests and securities (any, “Securities”) of which are owned or acquired by the Pledgor and described
on an addendum hereto from time-to-time executed by the Pledgor in form and substance satisfactory to the Collateral Agent (each such
entity is referred to herein as a “Pledge Entity” and collectively as the “Pledge Entities,” which shall include
all subsidiaries of the Pledgor during the time this Agreement remains in effect); provided that the parties hereto agree that, as of
the date hereof, the Pledge Entities specified on Exhibit A are the only Pledge Entities. The failure to execute an addendum shall
not relieve the Pledgor of its obligation to pledge any after acquired Securities.


 


D.   Pursuant
to a Security Agreement dated as of the date of this Agreement by and among the Collateral Agent, the Pledgor and the other entities party
thereto as “Debtors” (as the same may be amended, restated, modified or supplement and in effect from time to time, the “Security
Agreement”), the Pledgor and each other Debtor has granted the Collateral Agent, for its benefit and the benefit of the other Purchasers,
a first priority security interest in, lien upon and pledge of all of such Pledgor’s or other Debtor’s rights in such Pledgor’s
or other Debtor’s Collateral (as defined in the Security Agreement).


 


To induce the Purchasers to
enter into the Purchase Agreement, purchase the Advance Notes and to make the financial accommodations available to the Pledgor under
the Purchase Agreement, and in order to secure the payment and performance by the Pledgor of the Obligations (as hereafter defined), the
Pledgor has agreed to pledge to the Purchasers all of the Securities (the “Pledged Equity”) of the Pledge Entities now or
hereafter owned or acquired by such Pledgor to secure the Obligations (as defined in the Security Agreement).


 






    F-1


     


    

 


NOW, THEREFORE, in consideration
of the premises and in order to induce the Purchasers to purchase the Advance Notes under the Purchase Agreement and for other good and
valuable consideration, the receipt and sufficiency of which are hereby acknowledged, the Pledgor hereby agrees with the Collateral Agent
as follows:


 


1.   Defined
Terms. Unless otherwise defined herein, all capitalized terms used herein shall have the meanings given them in the Purchase Agreement.


 


2.   Pledge.


 


(a)   The
Pledgor hereby pledges, assigns, hypothecates, transfers, delivers and grants to the Collateral Agent, for the benefit of itself and the
other Purchasers, a first lien on and first priority perfected security interest in (i) all of the Pledged Equity of the Pledge Entities
now owned or hereafter acquired by such Pledgor (collectively, the “Pledged Interests”), (ii) any other shares of Pledged
Equity hereafter pledged or referred to be pledged to the Collateral Agent pursuant to this Agreement; (ii) all “investment property”
as such term is defined in §9-102(a)(49) of the UCC (as defined below) with respect thereto; (iv) any “security entitlement”
as such term is defined in § 8-102(a)(17) of the UCC with respect thereto; (v) all books and records relating to the foregoing; and
(vi) all Accessions and Proceeds (as each is defined in the UCC) of the foregoing, including, without limitation, all distributions (cash,
stock, or otherwise), dividends, stock dividends, securities, cash, instruments, rights to subscribe, purchase, or sell, and other property,
rights, and interest that such Pledgor is at any time entitled to receive or is otherwise distributed in respect of, or in exchange for,
any or all of the Pledged Collateral (as defined below), and without affecting the obligations of the Pledgor under any provision of the
Security Agreement, in the event of any consolidation or merger in which the Pledgor is not the surviving corporation, all shares of each
class or Pledged Equity of the successor entity formed by or resulting from such consolidation or merger (the collateral described in
clauses (i) through (vi) of this Section 2 being collectively referred to as the “Pledged Collateral”), as collateral security
for the prompt and complete payment and performance when due (whether at the stated maturity, by acceleration or otherwise) of the Obligations.
All of the Pledged Interests now owned by the Pledgor, which are presently represented by certificates, are listed on Exhibit A
hereto, which certificates, with undated assignments separate from the certificates or stock/membership interest powers duly executed
in blank by such Pledgor and to the extent such certificates are available and not covered by an existing lien or pledge, or irrevocable
proxies, are being delivered to the Collateral Agent simultaneously herewith. Upon the creation or acquisition of any new Pledged Interests,
to the extent such certificates are available and not covered by an existing lien or pledge, the Pledgor shall execute an Addendum in
the form of Exhibit B attached hereto (a “Pledge Addendum”). Any Pledged Collateral described in a Pledge Addendum
executed by the Pledgor shall thereafter be deemed to be listed on Exhibit A hereto. The Collateral Agent shall maintain possession
and custody of the certificates representing the Pledged Interests and any additional Pledged Collateral.


 






    F-2


     


    

 


(b)   Each
Pledged Interest consisting of either (i) a membership interest in a Person that is a limited liability company or (ii) a partnership
interest in a Person that is a partnership (if any) (1) is not and will not be evidenced by a certificate and (2) is not and will not
be deemed a “security” governed by Article 8 of the UCC.


 


3.   Representations
and Warranties of Pledgor. The Pledgor represents and warrants to the Collateral Agent, and covenants with the Collateral Agent, that:


 


(a)   Exhibit
A sets forth (i) the authorized capital stock and other equity interests of each Pledge Entity, (ii) the number of shares of capital
stock and other equity interests of each Pledge Entity that are issued and outstanding as of the date hereof, and (iii) the percentage
of the issued and outstanding shares of capital stock and other equity interests of each Pledge Entity held by such Pledgor. Such Pledgor
is the record and beneficial owner of, and has good and marketable title to, the Pledged Interests of such Pledgor, and such shares are
and will remain free and clear of all pledges, liens, security interests and other encumbrances and restrictions whatsoever, except the
liens and security interests in favor of the Collateral Agent created by this Agreement;


 


(b)   Except
as set forth on Exhibit A, there are no outstanding options, warrants or other similar agreements with respect to the Pledged Interests
or any of the other Pledged Collateral;


 


(c)   This
Agreement is the legal, valid and binding obligation of the Pledgor, enforceable against the Pledgor in accordance with its terms except
to the extent that such enforceability is subject to applicable bankruptcy, insolvency, reorganization, fraudulent conveyance and moratorium
laws and other laws of general application affecting enforcement of creditors’ rights generally, or the availability of equitable
remedies, which are subject to the discretion of the court before which an action may be brought;


 


(d)   The
Pledged Interests have been duly and validly authorized and issued, are fully paid and non-assessable, and the Pledged Interests listed
on Exhibit A constitute all of the issued and outstanding capital stock or other equity interests of the Pledge Entities;


 


(e)   No
consent, approval or authorization of or designation or filing with any governmental or regulatory authority on the part of the Pledgor
is required in connection with the pledge and security interest granted under this Agreement;


 


(f)   The
execution, delivery and performance of this Agreement will not violate any provision of any applicable law or regulation or of any order,
judgment, writ, award or decree of any court, arbitrator or governmental authority, which are applicable to the Pledgor, or of the articles
or certificate of incorporation, certificate of formation, bylaws or any other similar organizational documents of the Pledgor or any
Pledge Entity or of any securities issued by the Pledgor or any Pledge Entity of any mortgage, indenture, lease, contract, or other agreement,
instrument or undertaking to which the Pledgor or any Pledge Entity is a party or which is binding upon the Pledgor or any Pledge Entity
or upon any of the assets of the Pledgor or any Pledge Entity, and will not result in the creation or imposition of any lien, charge or
encumbrance on or security interest in any of the assets of the Pledgor or any Pledge Entity, except as otherwise contemplated by this
Agreement;


 






    F-3


     


    

 


(g)   The
pledge, assignment and delivery of the Pledged Interests and the other Pledged Collateral pursuant to this Agreement creates a valid first
lien on and perfected first priority security interest in such Pledged Interests and Pledged Collateral and the proceeds thereof in favor
of the Collateral Agent, subject to the security interests reflected on Exhibit B. Until this Agreement is terminated pursuant
to Section 11 hereof, the Pledgor covenants and agrees that it will defend, for the benefit of the Collateral Agent and each other Purchaser,
the Collateral Agent’s right, title and security interest in and to the Pledged Interests, the other Pledged Collateral and the
proceeds thereof against the claims and demands of all other Persons; and


 


(h)   Neither
the Pledgor nor any Pledged Entity (i) will become a Person whose property or interests in property are blocked or subject to blocking
pursuant to Section 1 of Executive Order 13224 of September 23, 2001 Blocking Property and Prohibiting Transactions with Persons Who Commit,
Threaten to Commit or Support Terrorism (66 Fed. Reg. 49079(2001), (ii) will engage in any dealings or transactions prohibited by Section
2 of such executive order, or (iii) will otherwise become a Person on the list of Specially Designated Nationals and Blocked Persons or
subject to the limitations or prohibitions under any other Office of Foreign Asset Control regulation or executive order.


 


4.   Dividends,
Distributions, Etc. If, prior to irrevocable repayment in full in cash of the Obligations, the Pledgor shall receive any certificate
(including, without limitation, any certificate representing a dividend or a distribution in connection with any reclassification, increase
or reduction of capital, or issued in connection with any reorganization, merger or consolidation), or any options or rights, whether
as an addition to, in substitution for, or in exchange for any of the Pledged Interests or otherwise, such Pledgor agrees, in each case,
to accept the same as the Collateral Agent’s agent and to hold the same in trust for the Collateral Agent, and to deliver the same
promptly (but in any event within five days) to the Collateral Agent in the exact form received, with the endorsement of such Pledgor
when necessary and/or with appropriate undated assignments separate from certificates or stock powers duly executed in blank, to be held
by the Collateral Agent subject to the terms hereof, as additional Pledged Collateral. The Pledgor shall promptly deliver to the Collateral
Agent (i) a Pledge Addendum with respect to such additional certificates, and (ii) any financing statements or amendments to financing
statements as requested by the Collateral Agent. The Pledgor hereby authorizes the Collateral Agent to attach each such Pledge Addendum
to this Agreement. Except as provided in Section 5(b) below, all sums of money and property so paid or distributed in respect of the Pledged
Interests which are received by the Pledgor shall, until paid or delivered to the Collateral Agent, be held by the Pledgor in trust as
additional Pledged Collateral.


 


5.   Voting
Rights; Dividends; Certificates.


 


(a)   So
long as no Event of Default (as defined in the Advance Notes) has occurred and is continuing, the Pledgor shall be entitled (subject to
the other provisions hereof, including, without limitation, Section 8 below) to exercise its voting and other consensual rights with respect
to the Pledged Interests and otherwise exercise the incidents of ownership thereof in any manner not inconsistent with this Agreement,
the Purchase Agreement and/or any of the other Transaction Documents. The Pledgor hereby grants to the Pledgee or its nominee, an irrevocable
proxy to exercise all voting, corporate and limited liability company rights relating to the Pledged Interests in any instance, which
proxy shall be effective, at the discretion of the Collateral Agent, upon the occurrence and during the continuance of an Event of Default.
Upon the request of the Collateral Agent at any time, the Pledgor agrees to deliver to the Collateral Agent such further evidence of such
irrevocable proxy or such further irrevocable proxies to vote the Pledged Interests as the Collateral Agent may request.


 






    F-4


     


    

 


(b)   So
long as no Event of Default shall have occurred and be continuing, the Pledgor shall be entitled to receive cash dividends or other distributions
made in respect of the Pledged Interests, to the extent permitted to be made pursuant to the terms of the Advance Notes and the Purchase
Agreement. Upon the occurrence and during the continuance of an Event of Default, in the event that the Pledgor, as record and beneficial
owner of the Pledged Interests, shall have received or shall have become entitled to receive, any cash dividends or other distributions
in the ordinary course, such Pledgor shall deliver to the Collateral Agent, and the Collateral Agent shall be entitled to receive and
retain, for the benefit of itself and the other Purchasers, all such cash or other distributions as additional security for the Obligations.


 


(c)   Subject
to any sale or other disposition by the Collateral Agent of the Pledged Interests, any other Pledged Collateral or other property pursuant
to this Agreement, upon the indefeasible full payment in cash, satisfaction and termination of all of the Obligations and the termination
of this Agreement pursuant to Section 11 hereof and of the liens and security interests hereby granted, the Pledged Interests, the other
Pledged Collateral and any other property then held as part of the Pledged Collateral in accordance with the provisions of this Agreement
shall be returned to the Pledgor or to such other Persons as shall be legally entitled thereto.


 


(d)   The
Pledgor shall cause all Pledged Interests (other than the Pledged Interests consisting of limited liability company interests) to be certificated
at all times while this Agreement is in effect.


 


6.   Rights
of Collateral Agent. The Collateral Agent shall not be liable for failure to collect or realize upon the Obligations or any collateral
security or guaranty therefor, or any part thereof, or for any delay in so doing, nor shall the Collateral Agent be under any obligation
to take any action whatsoever with regard thereto. Any or all of the Pledged Interests held by the Collateral Agent hereunder may, if
an Event of Default has occurred and is continuing, without notice, be registered in the name of the Collateral Agent or its nominee,
and the Collateral Agent or its nominee may thereafter without notice exercise all voting and corporate rights at any meeting with respect
to any Pledge Entity and exercise any and all rights of conversion, exchange, subscription or any other rights, privileges or options
pertaining to any of the Pledged Interests as if it were the absolute owner thereof, including, without limitation, the right to vote
in favor of, and to exchange at its discretion any and all of the Pledged Interests upon the merger, consolidation, reorganization, recapitalization
or other readjustment with respect to any Pledge Entity or upon the exercise by any Pledge Entity, the Pledgor or the Collateral Agent
of any right, privilege or option pertaining to any of the Pledged Interests, and in connection therewith, to deposit and deliver any
and all of the Pledged Interests with any committee, depository, transfer agent, registrar or other designated agency upon such terms
and conditions as the Collateral Agent may reasonably determine, all without liability except to account for property actually received
by the Collateral Agent, but the Collateral Agent shall have no duty to exercise any of the aforesaid rights, privileges or options and
shall not be responsible for any failure to do so or delay in so doing.


 






    F-5


     


    

 


7.   Remedies.
Upon the occurrence and during the continuance of an Event of Default, the Collateral Agent may exercise in respect of the Pledged Collateral,
in addition to other rights and remedies provided for herein or otherwise available to it, all the rights and remedies of a secured party
under the Uniform Commercial Code (“UCC”) of the jurisdiction applicable to the affected Pledged Collateral from time-to-time.
Without limiting the foregoing, the Collateral Agent may, without demand of performance or other demand, advertisement or notice of any
kind (except the notice specified below of time and place of public or private sale) to or upon the Pledgor or any other Person (all and
each of which demands, advertisements and/or notices are hereby expressly waived), upon the occurrence and during the continuance of an
Event of Default forthwith collect, receive, appropriate and realize upon the Pledged Collateral, or any part thereof, and/or may forthwith
date and otherwise fill in the blanks on any assignments separate from certificates or stock powers or otherwise sell, assign, give an
option or options to purchase, contract to sell or otherwise dispose of and deliver said Pledged Collateral, or any part thereof, in one
or more portions at one or more public or private sales or dispositions, at any exchange or broker’s board or at any of the Collateral
Agent’s offices or elsewhere upon such terms and conditions as the Collateral Agent may deem advisable and at such prices as it
may deem best, for any combination of cash and/or securities or other property or on credit or for future delivery without assumption
of any credit risk, with the right to the Collateral Agent upon any such sale, public or private, to purchase the whole or any part of
said Pledged Collateral so sold, free of any right or equity of redemption in the Pledgor, which right or equity is hereby expressly waived
or released. The Collateral Agent shall apply the net proceeds of any such collection, recovery, receipt, appropriation, realization,
sale or disposition, after deducting all costs and expenses of every kind incurred therein or incidental to the safekeeping of any and
all of the Pledged Collateral or in any way relating to the rights of the Collateral Agent hereunder, including reasonable attorneys’
fees and legal expenses, to the payment, in whole or in part, of the Obligations, in such order as the Collateral Agent may elect. The
Pledgor shall remain liable for any deficiency remaining unpaid after such application. Only after so paying over such net proceeds and
after the payment by the Collateral Agent of any other amount required by any provision of law, including, without limitation, Section
9-608 of the UCC, need the Collateral Agent account for the surplus, if any, to the Pledgor. The Pledgor agrees that the Collateral Agent
need not give more than ten (10) days’ notice of the time and place of any public sale or of the time after which a private sale
or other intended disposition is to take place and that such notice is reasonable notification of such matters. No notification need be
given to the Pledgor if after default it has signed a statement renouncing or modifying any right to notification of sale or other intended
disposition. Notwithstanding any provision in any shareholder’s agreement or any applicable laws to the contrary, the Pledgor acknowledge
and agrees that the Pledgor may pledge to the Collateral Agent all of the Pledgor’s right, title and interest in all of the Pledged
Entities, and upon foreclosure the successful bidder (which may include the Collateral Agent) will be deemed admitted as a member and/or
shareholder, as applicable, of each Pledged Entity, and will automatically succeed to all of the Pledgor’s right, title and interest,
including without limitation, the Pledgor’s limited liability company and equity interests, right to vote and participate in the
management and business affairs of the Pledged Entities, right to a share of the profits and losses of the Pledged Entities and right
to receive distributions from the Pledged Entities.


 


8.   No
Disposition, Etc. Until the irrevocable payment in full, satisfaction or expiration of the Obligations, the Pledgor agrees that it
will not sell, assign, transfer, exchange, or otherwise dispose of, or grant any option with respect to, the Pledged Interests or any
other Pledged Collateral, nor will the Pledgor create, incur or permit to exist any Lien or other encumbrance with respect to any of the
Pledged Interests or any other Pledged Collateral, or any interest therein, or any proceeds thereof, except for the Lien and security
interest of the Collateral Agent provided for by this Agreement and the Security Agreement and Permitted Liens as defined in the Advance
Notes.


 






    F-6


     


    

 


9.   Sale
of Pledged Interests.


 


(a)   The
Pledgor recognizes that the Collateral Agent may be unable to effect a public sale or disposition (including, without limitation, any
disposition in connection with a merger of a Pledged Entity) of any or all the Pledged Interests by reason of certain prohibitions contained
in the Securities Act, and applicable state securities laws, but may be compelled to resort to one or more private sales or dispositions
thereof to a restricted group of purchasers who will be obliged to agree, among other things, to acquire such securities for their own
account, for investment and not with a view to the distribution or resale thereof. The Pledgor acknowledges and agrees that any such private
sale or disposition may result in prices and other terms (including the terms of any securities or other property received in connection
therewith) less favorable to the seller than if such sale or disposition were a public sale or disposition and the Pledgor agrees that
it is not commercially unreasonable for the Collateral Agent to engage in any such private sales or dispositions under such circumstances.
The Collateral Agent shall be under no obligation to delay a sale or disposition of any of the Pledged Interests in order to permit the
Pledgor or a Pledged Entity to register such securities for public sale under the Securities Act, or under applicable state securities
laws, even if such Pledgor or a Pledged Entity would agree to do so.


 


(b)   The
Pledgor further agrees to do or cause to be done all such other acts and things as may be reasonably necessary to make such sales or dispositions
of the Pledged Interests valid and binding and in compliance with any and all applicable laws, regulations, orders, writs, injunctions,
decrees or awards of any and all courts, arbitrators or governmental instrumentalities, domestic or foreign, having jurisdiction over
any such sales or dispositions, all at such Pledgor’s expense; provided that the Pledgor shall not have any obligation to
register the Pledged Interests as securities under the Securities Act or the applicable state securities laws solely by virtue of this
Section 9(b). The Pledgor further agrees that a breach of any of the covenants contained in Sections 4, 5(a), 5(b), 8, 9 and 24 will cause
irreparable injury to the Collateral Agent and that the Collateral Agent has no adequate remedy at law in respect of such breach and,
as a consequence, agrees, without limiting the right of the Collateral Agent to seek and obtain injunctive relief and/or specific performance
of other obligations of the Pledgor contained in this Agreement, that each and every covenant referenced above shall be specifically enforceable
against the Pledgor, and the Pledgor hereby waives and agrees not to assert any defenses against an action for specific performance of
such covenants. The Collateral Agent shall not be required to post a bond or other security as a condition of obtaining equitable relief.


 


(c)   The
Pledgor further agrees to indemnify and hold harmless the Collateral Agent and each other Purchaser, their respective successors and assigns
and all of their collective officers, directors, shareholders, members, managers, partners, employees, attorneys and agents, and any Person
in control of any thereof, from and against any loss, liability, claim, damage and expense, including, without limitation, legal fees
and expenses (in this paragraph collectively called the “Indemnified Liabilities”), under federal and state securities laws
or otherwise insofar as such Indemnified Liability (i) arises out of or is based upon any untrue statement or alleged untrue statement
of a material fact contained in any registration statement, prospectus or offering memorandum or in any preliminary prospectus or preliminary
offering memorandum or in any amendment or supplement to any thereof or in any other writing prepared by the Pledgor in connection with
the offer, sale or resale of all or any portion of the Pledged Collateral unless such untrue statement of material fact was provided by
the Collateral Agent, in writing, specifically for inclusion therein, or (ii) arises out of or is based upon any omission or alleged omission
to state therein a material fact required to be stated or necessary to make the statements therein not misleading, such indemnification
to remain operative regardless of any investigation made by or on behalf of the Collateral Agent or any successor thereof, or any Person
in control of any thereof. In connection with a public sale or other distribution, the Pledgor will provide customary indemnification
to any underwriters, their successors and assigns, officers and directors and each Person who controls any such underwriter (within the
meaning of the Securities Act). If and to the extent that the foregoing undertakings in this paragraph may be unenforceable for any reason,
the Pledgor agrees to make the maximum contribution to the payment and satisfaction of each of the Indemnified Liabilities which is permissible
under applicable law. The obligations of the Pledgor under this paragraph (c) shall survive any termination of this Agreement.


 






    F-7


     


    

 


(d)   The
Pledgor further agrees not to exercise any and all rights of subrogation it may have against a Pledged Entity upon the sale or disposition
of all or any portion of the Pledged Collateral by the Collateral Agent pursuant to the terms of this Agreement until the termination
of this Agreement in accordance with Section 11 below.


 


10.   No
Waiver; Cumulative Remedies. The Collateral Agent shall not by any act, delay, omission or otherwise be deemed to have waived any
of its remedies hereunder, and no waiver by the Collateral Agent shall be valid unless in writing and signed by the Collateral Agent,
and then only to the extent therein set forth. A waiver by the Collateral Agent of any right or remedy hereunder on any one occasion shall
not be construed as a bar to any right or remedy which the Collateral Agent would otherwise have on any further occasion. No course of
dealing between the Pledgor and the Collateral Agent or any other Purchaser, and no failure to exercise, nor any delay in exercising on
the part of the Collateral Agent or any other Purchaser of, any right, power or privilege hereunder or under the other Transaction Documents
shall impair such right or remedy or operate as a waiver thereof; nor shall any single or partial exercise of any right, power or privilege
hereunder preclude any other or further exercise thereof or the exercise of any other right, power or privilege. The rights and remedies
herein provided are cumulative and may be exercised singly or concurrently, and are not exclusive of any rights or remedies provided by
law or in the Purchase Agreement.


 


11.   Termination.
This Agreement and the Liens and security interests granted hereunder shall terminate and the Collateral Agent, at the Pledgor’s
sole reasonable cost and reasonable expense, shall immediately return any Pledged Interests or other Pledged Collateral then held by the
Collateral Agent in accordance with the provisions of this Agreement to the Pledgor upon the full and complete performance and indefeasible
satisfaction of all of the Obligations (including, without limitation, the indefeasible payment in full in cash of all such Obligations)
(i) in respect of the Transaction Documents, and (ii) with respect to which claims have been asserted by the Collateral Agent and/or any
other Purchaser.


 


12.   Possession
of Collateral. Beyond the exercise of reasonable care to assure the safe custody of the Pledged Interests in the physical possession
of the Collateral Agent pursuant hereto, neither the Collateral Agent, nor any nominee of the Collateral Agent, shall have any duty or
liability to collect any sums due in respect thereof or to protect, preserve or exercise any rights pertaining thereto (including any
duty to ascertain or take action with respect to calls, conversions, exchanges, maturities, tenders or other matters relating to the Pledged
Collateral and any duty to take any necessary steps to preserve rights against any parties with respect to the Pledged Collateral), and
