Rule and further, if said Rule is not applicable, any re-sale of such Securities under circumstances in which the seller (or the
person through whom the sale is made) may be deemed to be an underwriter (as that term is defined in the 1933 Act) may require
compliance with some other exemption under the 1933 Act or the rules and regulations of the SEC thereunder; and (iii) neither the

not be deemed to be a transfer, sale or assignment of the Securities hereunder, and the Buyer in effecting such pledge of Securities
shall be not required to provide the Company with any notice thereof or otherwise make any delivery to the Company pursuant to this
Agreement or otherwise.

 

g.

the Warrant in accordance with its respective terms, the Conversion Shares and/or Warrant Shares, have been registered under the 1933
Act or may be sold pursuant to Rule 144 under the 1933 Act, or other applicable exemption without any restriction as to the number of
securities as of a particular date that can then be immediately sold, the Securities may bear a restrictive legend in substantially the
following form (and a stop-transfer order may be placed against transfer of such Securities):

 

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

 

The
legend set forth above shall be removed and the Company shall issue a certificate or book entry statement for the applicable shares of
Common Stock without such legend to the holder of any Security upon which it is stamped or (as requested by such holder) issue the applicable
shares of Common Stock to such holder by electronic delivery by crediting the account of such holder’s broker with The Depository
Trust Company (“DTC”), if, unless otherwise required by applicable state securities laws, (a) such Security is registered
for sale under an effective registration statement filed under the 1933 Act or otherwise may be sold pursuant to Rule 144, Rule 144A,
Regulation S, or other applicable exemption without any restriction as to the number of securities as of a particular date that can then
be immediately sold, or (b) the Company or the Buyer provides the Legal Counsel Opinion (as contemplated by and in accordance with Section
4(m) hereof) to the effect that a public sale or transfer of such Security may be made without registration under the 1933 Act, which
opinion shall be accepted by the Company so that the sale or transfer is effected. The Company shall be responsible for the fees of its
transfer agent and all DTC fees associated with any such issuance. The Buyer agrees to sell all Securities, including those represented
by a certificate(s) from which the legend has been removed, in compliance with applicable prospectus delivery requirements, if any. In
the event that the Company does not accept the opinion of counsel provided by the Buyer with respect to the transfer of Securities pursuant
to an exemption from registration, such as Rule 144 or other applicable exemption at the Deadline (as defined in the Note), it will be
considered an Event of Default pursuant to Section 3.2 of the Note.

and authority (corporate and other) to own, lease, use and operate its properties and to carry on its business as and where now owned,
leased, used, operated and conducted. Schedule 3(a), if attached hereto, sets forth a list of all of the Material Subsidiaries of the
Company and the jurisdiction in which each is incorporated. The Company and each of its Material Subsidiaries is duly qualified as a
foreign corporation to do business and is in good standing in every jurisdiction in which its ownership or use of property or the nature
of the business conducted by it makes such qualification necessary except where the failure to be so qualified or in good standing would
not have a Material Adverse Effect. “Material Adverse Effect” means any material adverse effect on the business, operations,
assets, financial condition or prospects of the Company or its Material Subsidiaries, if any, taken as a whole, or on the transactions
contemplated hereby or by the agreements or instruments to be entered into in connection herewith. “Material Subsidiaries”
means any corporation or other organization, whether incorporated or unincorporated, in which the Company owns, directly or indirectly,
a majority of the voting equity or otherwise controls such subsidiary and consolidates such subsidiary in its financial statements prepared
in accordance with generally accepted accounting principles.

of the Note and/or Warrant Shares issuable upon exercise of the Warrant) have been duly authorized by the Company’s Board of Directors
and no further consent or authorization of the Company, its Board of Directors, its shareholders, or its debt holders is required, (iii)
this Agreement and the Note (together with any other instruments executed in connection herewith or therewith) have been duly executed
and delivered by the Company by its authorized representative, and such authorized representative is the true and official representative
with authority to sign this Agreement, the Note and the other instruments documents executed in connection herewith or therewith and
bind the Company accordingly, and (iv) this Agreement constitutes, and upon execution and delivery by the Company of the Note, each of
such instruments will constitute, a legal, valid and binding obligation of the Company, enforceable against the Company in accordance
with their terms.

 

c.
Capitalization; Governing Documents. As of March 31, 2022, the authorized capital stock of the Company consists of: 2,000,000,000

stock of the Company are subject to preemptive rights or any other similar rights of the shareholders of the Company or any liens or
encumbrances imposed through the actions or failure to act of the Company. As of the effective date of this Agreement, other than as
publicly announced prior to such date and reflected in the SEC Documents of the Company and other than contracts with consultants James
Cook, Jeffrey Witkin and Roc Cerne, , each of which contracts includes payment in stock or other equity-linked securities, vesting over
time (i) there are no outstanding options, warrants, scrip, rights to subscribe for, puts, calls, rights of first refusal, agreements,
understandings, claims or other commitments or rights of any character whatsoever relating to, or securities or rights convertible into
or exchangeable for any shares of capital stock of the Company or any of its Material Subsidiaries, or arrangements by which the Company
or any of its Material Subsidiaries is or may become bound to issue additional shares of capital stock of the Company or any of its Material
Subsidiaries, (ii) there are no agreements or arrangements under which the Company or any of its Material Subsidiaries is obligated to

of Incorporation as in effect on the date hereof (“Certificate of Incorporation”), the Company’s By-laws, as in effect

d.
Issuance of Conversion Shares and Warrant Shares. The Conversion Shares and Warrant Shares are duly authorized and reserved for
issuance and, upon conversion of the Note in accordance with its terms, will be validly issued, fully paid and non-assessable, and free

similar rights of shareholders of the Company and will not impose personal liability upon the holder thereof.

 

e.
Issuance of Warrant. The issuance of the Warrant is duly authorized and will be validly issued, fully paid and non-assessable,
and free from all taxes, liens, claims and encumbrances with respect to the issue thereof and shall not be subject to preemptive rights
or other similar rights of shareholders of the Company and will not impose personal liability upon the holder thereof.

 

f.
Acknowledgment of Dilution. The Company understands and acknowledges the potentially dilutive effect of the Conversion Shares
and Warrant Shares to the Common Stock upon the conversion of the Note and/or exercise of the Warrant. The Company further acknowledges
that its obligation to issue, upon conversion of the Note, the Conversion Shares, and upon exercise of the Warrant, the Warrant Shares,
in accordance with this Agreement, and the Note are absolute and unconditional regardless of the dilutive effect that such issuance may
have on the ownership interests of other shareholders of the Company.

 

g.
Ranking; No Conflicts. The Note shall be pari passu in payment and performance with all unsecured indebtedness of the Company.
The execution, delivery and performance of this Agreement and the Note by the Company and the consummation by the Company of the transactions
contemplated hereby and thereby (including, without limitation, the issuance and reservation for issuance of the Conversion Shares and
Warrant Shares) will not (i) conflict with or result in a violation of any provision of the Certificate of Incorporation or By-laws,
or (ii) violate or conflict with, or result in a breach of any provision of, or constitute a default (or an event which with notice or
lapse of time or both could become a default) under, or give to others any rights of termination, amendment, acceleration or cancellation
of, any agreement, note, evidence of indebtedness, indenture, patent, patent license or instrument to which the Company or any of its
Material Subsidiaries is a party, or (iii) result in a violation of any law, rule, regulation, order, judgment or decree (including federal
and state securities laws and regulations and regulations of any self-regulatory organizations to which the Company or its securities
is subject) applicable to the Company or any of its Material Subsidiaries or by which any property or asset of the Company or any of
its Material Subsidiaries is bound or affected (except for such conflicts, defaults, terminations, amendments, accelerations, cancellations
and violations as would not, individually or in the aggregate, have a Material Adverse Effect), or (iv) trigger any anti- dilution and/or
ratchet provision contained in any other contract in which the Company is a party thereto or any security issued by the Company. Neither
the Company nor any of its Material Subsidiaries is in violation of its Certificate of Incorporation, By-laws or other organizational
documents and neither the Company nor any of its Material Subsidiaries is in default (and no event has occurred which with notice or
lapse of time or both could put the Company or any of its Material Subsidiaries in default) under, and neither the Company nor any of
its Material Subsidiaries has taken any action or failed to take any action that would give to others any rights of termination, amendment,
acceleration or cancellation of, any agreement, indenture or instrument to which the Company or any of its Material Subsidiaries is a
party or by which any property or assets of the Company or any of its Material Subsidiaries is bound or affected, except for possible
defaults as would not, individually or in the aggregate, have a Material Adverse Effect. The businesses of the Company and its Material
Subsidiaries, if any, are not being conducted, and shall not be conducted so long as the Buyer owns any of the Securities, in violation
of any law, ordinance or regulation of any governmental entity. Except as specifically contemplated by this Agreement and as required
under the 1933 Act and any applicable state securities laws, the Company is not required to obtain any consent, authorization or order
of, or make any filing or registration with, any court, governmental agency, regulatory agency, self-regulatory organization or stock
market or any third party in order for it to execute, deliver or perform any of its obligations under this Agreement and the Note in
accordance with the terms hereof or thereof or to issue and sell the Note in accordance with the terms hereof and, upon conversion of
the Note and/or exercise of the Warrant, issue Conversion Shares and/or Warrant Shares. All consents, authorizations, orders, filings
and registrations which the Company is required to obtain pursuant to the preceding sentence have been obtained or effected on or prior
to the date hereof. The Company is not in violation of the listing requirements of the Principal Market (as defined herein) and does
not reasonably anticipate that the Common Stock will be delisted by the Principal Market in the foreseeable future. The Company and its
Material Subsidiaries are unaware of any facts or circumstances which might give rise to any of the foregoing. The Principal Market shall
mean any tier of the OTC Markets, any tier of the NASDAQ Stock Market (including NASDAQ Capital Market), or the NYSE American, or any
successor to such markets.

h.
SEC Documents; Financial Statements. The Company has timely filed all reports, schedules, forms, statements and other documents
required to be filed by it with the SEC pursuant to the reporting requirements of the Securities Exchange Act of 1934, as amended (the
“1934 Act”) (all of the foregoing filed prior to the date hereof and all exhibits included therein and financial statements
and schedules thereto and documents (other than exhibits to such documents) incorporated by reference therein, being herein referred
to as the “SEC Documents”). As of their respective dates, the SEC Documents complied in all material respects with the requirements
of the 1934 Act and the rules and regulations of the SEC promulgated thereunder applicable to the SEC Documents, and none of the SEC
Documents, at the time they were filed with the SEC, contained any untrue statement of a material fact or omitted to state a material
fact required to be stated therein or necessary in order to make the statements therein, in light of the circumstances under which they
were made, not misleading. None of the statements made in any such SEC Documents is, or has been, required to be amended or updated under
applicable law (except for such statements as have been amended or updated in subsequent filings prior the date hereof) and other than
the pre-existing Form S- 1 and the related prospectus with respect to the equity line and the related equity purchase agreement with
White Lion Capital LLC (the “Equity Line”). As of their respective dates, the financial statements of the Company included
in the SEC Documents complied as to form in all material respects with applicable accounting requirements and the published rules and
regulations of the SEC with respect thereto. Such financial statements have been prepared in accordance with United States generally
accepted accounting principles, consistently applied, during the periods involved and fairly present in all material respects the consolidated
financial position of the Company and its consolidated Material Subsidiaries as of the dates thereof and the consolidated results of
their operations and cash flows for the periods then ended (subject, in the case of unaudited statements, to normal year-end audit adjustments).
Except as set forth in the financial statements of the Company included in the SEC Documents, the Company has no liabilities, contingent
or otherwise, other than (i) liabilities incurred in the ordinary course of business subsequent to June 30, 2021, and (ii) obligations
under contracts and commitments incurred in the ordinary course of business and not required under generally accepted accounting principles
to be reflected in such financial statements, which, individually or in the aggregate, are not material to the financial condition or
operating results of the Company. The Company is subject to the reporting requirements of the 1934 Act. The Company has never been a
“shell company” as described in Rule 144(i)(1)(i).

 

i.
Absence of Certain Changes. Since September 30, 2021, there has been no material adverse change and no material adverse development
in the assets, liabilities, business, properties, operations, financial condition, results of operations, prospects or 1934 Act reporting
status of the Company or any of its Material Subsidiaries.

 

j.
Absence of Litigation. Other than as disclosed in the SEC Documents, there is no action, suit, claim, proceeding, inquiry or investigation
before or by any court, public board, government agency, self- regulatory organization or body pending or, to the knowledge of the Company
or any of its Material Subsidiaries, threatened against or affecting the Company or any of its Material Subsidiaries, or their officers
or directors in their capacity as such, that could have a Material Adverse Effect. The SEC Documents contain a complete list and summary
description of any pending or, to the knowledge of the Company, threatened proceeding against or affecting the Company or any of its
Material Subsidiaries. The Company and its Material Subsidiaries are unaware of any facts or circumstances which might give rise to any
of the foregoing.

 

k.
Intellectual Property. The Company and each of its Material Subsidiaries owns or possesses the requisite licenses or rights to
use all patents, patent applications, patent rights, inventions, know-how, trade secrets, trademarks, trademark applications, service
marks, service names, trade names and copyrights (“Intellectual Property”) necessary to enable it to conduct its business
as now operated (and, as presently contemplated to be operated in the future); there is no claim or action by any person pertaining to,
or proceeding pending, or to the Company’s knowledge threatened, which challenges the right of the Company or of a Material Subsidiary
with respect to any Intellectual Property necessary to enable it to conduct its business as now operated (and, as presently contemplated
to be operated in the future); to the best of the Company’s knowledge, the Company’s or its Material Subsidiaries’
current and intended products, services and processes do not infringe on any Intellectual Property or other rights held by any person;
and the Company is unaware of any facts or circumstances which might give rise to any of the foregoing. The Company and each of its Material
Subsidiaries have taken reasonable security measures to protect the secrecy, confidentiality and value of their Intellectual Property.

 

    	6

     

    

 

l.
No Materially Adverse Contracts, Etc. Neither the Company nor any of its Material Subsidiaries is subject to any charter, corporate
or other legal restriction, or any judgment, decree, order, rule or regulation which in the judgment of the Company’s officers
has or is expected in the future to have a Material Adverse Effect. Neither the Company nor any of its Material Subsidiaries is a party
to any contract or agreement which in the judgment of the Company’s officers has or is expected to have a Material Adverse Effect.

 

m.
Tax Status. Except as noted in the Section 3(m), the Company and each of its Material Subsidiaries has made or filed all federal,
state and foreign income and all other tax returns, reports and declarations required by any jurisdiction to which it is subject (unless
and only to the extent that the Company and each of its Material Subsidiaries has set aside on its books provisions reasonably adequate
for the payment of all unpaid and unreported taxes) and has paid all taxes and other governmental assessments and charges that are material
in amount, shown or determined to be due on such returns, reports and declarations, except those being contested in good faith and has
set aside on its books provisions reasonably adequate for the payment of all taxes for periods subsequent to the periods to which such
returns, reports or declarations apply. There are no unpaid taxes in any material amount claimed to be due by the taxing authority of
any jurisdiction, and the officers of the Company know of no basis for any such claim. The Company has not executed a waiver with respect
to the statute of limitations relating to the assessment or collection of any foreign, federal, state or local tax. None of the Company’s
tax returns is presently being audited by any taxing authority.

 

n.
Transactions with Affiliates. Except for arm’s length transactions pursuant to which the Company or any of its Material
Subsidiaries makes payments in the ordinary course of business upon terms no less favorable than the Company or any of its Material Subsidiaries
could obtain from third parties and other than transactions described in the SEC Documents and Exempt Issuances as described in the Note
and Warrant, none of the officers, directors, or employees of the Company is presently a party to any transaction with the Company or

otherwise requiring payments to or from any officer, director or such employee or, to the knowledge of the Company, any corporation,
partnership, trust or other entity in which any officer, director, or any such employee has a substantial interest or is an officer,
director, trustee or partner.

and correct in all material respects and the Company has not omitted to state any material fact necessary in order to make the statements
made herein or therein, in light of the circumstances under which they were made, not misleading. No event or circumstance has occurred
or exists with respect to the Company or any of its Material Subsidiaries or its or their business, properties, prospects, operations
or financial conditions, which, under applicable law, rule or regulation, requires public disclosure or announcement by the Company but
which has not been so publicly announced or disclosed.

 

p.

in the capacity of arm’s length purchaser with respect to this Agreement and the transactions contemplated hereby. The Company

that it will not be able to renew its existing insurance coverage as and when such coverage expires or to obtain similar coverage from
similar insurers as may be necessary to continue its business at a cost that would not have a Material Adverse Effect. Upon written request
the Company will provide to the Buyer true and correct copies of all policies relating to directors’ and officers’ liability

by applicable law. If under any circumstances whatsoever, interest in excess of the Maximum Rate is paid by the Company to the Buyer
with respect to indebtedness evidenced by this Agreement, the Note and any document, agreement or instrument contemplated thereby, such

agent and the Buyer a reliance letter (which reliance letter shall indicate that the transfer agent may rely on the opinion of Buyer’s
counsel). The Company hereby agrees that it may never take the position that it is a “shell company” in connection with its

include, but are not limited to, terms addressing prepayment rate, interest rates, and original issue discounts.

SEC, (ii) each subsequent Regulation A offering statement that the Company files with the SEC, and (iii) any amendment to any Regulation

the Buyer or its agents or counsel with any information that constitutes, or the Company reasonably believes constitutes, material non-public
information, unless prior thereto the Buyer 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 the Buyer shall be relying on the foregoing covenant in effecting
transactions in securities of the Company. To the extent that the Company delivers any material, non-public information to the Buyer
without such Buyer’s consent, the Company hereby covenants and agrees that such Buyer shall not have any duty of confidentiality
to the Company, any of its Material 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 Buyer shall remain subject to applicable law. To
the extent that any notice provided, information provided, or any other communications made by the Company, to the Buyer, constitutes

information, it shall pay the Buyer as partial liquidated damages and not as a penalty a sum equal to $3,000 per day beginning with the

Company shall provide, prior to the effective date of such replacement, a fully executed Irrevocable Transfer Agent Instructions in a
form as initially delivered pursuant to this Agreement (including but not limited to the provision to irrevocably reserve shares of Common

may be sold pursuant to Rule 144, Rule 144A, Regulation S, or other applicable exemption without any restriction as to the number of
Securities as of a particular date that can then be immediately sold, all such certificates shall bear the restrictive legend specified
in Section 2(g) of this Agreement. The Company warrants that: (i) no instruction other than the Irrevocable Transfer Agent Instructions

Note and this Agreement and (iv) it will provide any required corporate resolutions and issuance approvals to its transfer agent within
6 hours of each conversion of the Note. Nothing in this Section shall affect in any way the Buyer’s obligations and agreement set

for opinions in comparable transactions, to the effect that a public sale or transfer of such Securities may be made without registration
under the 1933 Act and such sale or transfer is effected or (ii) the Buyer provides reasonable assurances that the Securities can be
sold pursuant to 144, Rule 144A, Regulation S, or other applicable exemption, the Company shall permit the transfer, and, in the case
of the Securities, promptly instruct its transfer agent to issue one or more certificates, free from restrictive legend, in such name
and in such denominations as specified by the Buyer. The Company acknowledges that a breach by it of its obligations hereunder will cause
irreparable harm to the Buyer, by vitiating the intent and purpose of the transactions contemplated hereby. Accordingly, the Company

a breach or threatened breach by the Company of the provisions of this Section, that the Buyer shall be entitled, in addition to all
other available remedies, to an injunction restraining any breach and requiring immediate transfer, without the necessity of showing
economic loss and without any bond or other security being required.

m.
Indemnification. In consideration of the Buyer’s execution and delivery of this Agreement and acquiring the Securities hereunder,
and in addition to all of the Company’s other obligations under this Agreement or the Note, the Company shall defend, protect,
indemnify and hold harmless the Buyer and its stockholders, partners, members, officers, directors, employees and direct or indirect
investors and any of the foregoing persons’ agents or other representatives (including, without limitation, those retained in connection
with the transactions contemplated by this Agreement) (collectively, the “Indemnitees”) from and against any and all actions,
causes of action, suits, claims, losses, costs, penalties, fees, liabilities and damages, and expenses in connection therewith (irrespective
of whether any such Indemnitee is a party to the action for which indemnification hereunder is sought), and including reasonable attorneys’
fees and disbursements (the “Indemnified Liabilities”), incurred by any Indemnitee as a result of, or arising out of, or
relating to (a) any misrepresentation or breach of any representation or warranty made by the Company in this Agreement, the Note or
any other agreement, certificate, instrument or document contemplated hereby or thereby, (b) any breach of any covenant, agreement or
obligation of the Company contained in this Agreement, the Note or any other agreement, certificate, instrument or document contemplated
hereby or thereby or (c) any cause of action, suit or claim brought or made against such Indemnitee by a third party (including for these
purposes a derivative action brought on behalf of the Company) and arising out of or resulting from (i) the execution, delivery, performance
or enforcement of this Agreement, the Note or any other agreement, certificate, instrument or document contemplated hereby or thereby,
(ii) any transaction financed or to be financed in whole or in part, directly or indirectly, with the proceeds of the issuance of the
Securities, or (iii) the status of the Buyer or holder of the Securities as an investor in the Company pursuant to the transactions contemplated

make the maximum contribution to the payment and satisfaction of each of the Indemnified Liabilities that is permissible under applicable
law.

 

n.
Remedies. The Company acknowledges that a breach by it of its obligations hereunder will cause irreparable harm to the Buyer by
vitiating the intent and purpose of the transaction contemplated hereby. Accordingly, the Company acknowledges that the remedy at law
for a breach of its obligations under this Agreement, the Note, the Warrant, or any other agreement, certificate, instrument or document
contemplated hereby or thereby will be inadequate and agrees, in the event of a breach or threatened breach by the Company of the provisions
of this Agreement, the Note, the Warrant, or any other agreement, certificate, instrument or document contemplated hereby or thereby,
that the Buyer shall be entitled, in addition to all other available remedies at law or in equity, and in addition to the penalties assessable
herein, to an injunction or injunctions restraining, preventing or curing any breach of this Agreement, the Note, the Warrant, or any
other agreement, certificate, instrument or document contemplated hereby or thereby, and to enforce specifically the terms and provisions
hereof and thereof, without the necessity of showing economic loss and without any bond or other security being required.

 

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

 

p.
Failure or Indulgence Not Waiver. No failure or delay on the part of the Buyer in the exercise of any power, right or privilege
hereunder shall operate as a waiver thereof, nor shall any single or partial exercise of any such power, right or privilege preclude
other or further exercise thereof or of any other right, power or privileges. All rights and remedies of the Buyer existing hereunder
are cumulative to, and not exclusive of, any rights or remedies otherwise available. No failure or delay on the part of the Company in
the exercise of any power, right or privilege hereunder shall operate as a waiver thereof, nor shall any single or partial exercise of
any such power, right or privilege preclude other or further exercise thereof or of any other right, power or privileges. All rights
and remedies of the Company existing hereunder are cumulative to, and not exclusive of, any rights or remedies otherwise available.

provided however, that any references to Conversion Price shall have the meaning ascribed to it in the Note (the “Conversion

2.
Registration.

 

a.
Piggy-Back Registration. With respect to only one of the first three times the Company files a Registration Statement under the
Securities Act, and at the request of the Holder, the Company shall use its commercially reasonable efforts, to the extent permissible
under U.S. securities laws and the rules and regulations thereunder, to include the Piggy-Back Registrable Securities in such Registration
Statement with the intention of covering the resale of all of the Piggy-Back Registrable Securities at prevailing market prices (and
not fixed prices). The Company shall, to the extent permissible by U.S. securities laws and the rules and regulations thereunder initially
register for resale all of the Piggy-Back Registrable Securities, or an amount equal to the maximum amount allowed under the applicable
rule or rules as interpreted by the SEC. In the event the Company cannot register the Piggy-Back Registrable Securities, due to the remaining
number of authorized shares (including shares held in the share reservation established for the benefit of the Holder) of Common Stock
being insufficient, the Company will use its best efforts to register the maximum number of shares it can, based upon the remaining balance
of authorized shares (including shares held in the share reservation established for the benefit of the Holder) and will use its best
efforts to increase the number of its authorized shares as soon as reasonably practicable.

 

b.
The Company shall use its commercially reasonable efforts, if it elects to file a Registration Statement and to the extent permissible
under U.S. securities laws, to have the Registration Statement filed with the SEC within sixty (60) days following Holder’s request
for the inclusion of the Piggy-Back Registrable Securities in such Registration Statement (the “Filing Deadline”).

 

Notwithstanding
the foregoing, failure to file by the Filing Deadline shall not constitute an event of default under the Note to the extent any delay
in the filing of the Registration Statement occurs because of an act of, or a failure to act or to act timely by the Holder or is otherwise
solely attributable to the Holder.

 

The
Company acknowledges that its failure to have the Registration Statement filed by the Filing Deadline will cause the Holder to suffer
irreparable harm, and, that damages will be difficult to ascertain. Accordingly, the Parties agree that it is appropriate that the failure
to file by the Filing Deadline shall constitute an event of default under Section 3.3 of the Note. The availability of any remedies hereunder
and thereunder shall not relieve the Company from its obligations to register the Piggy-Back Registrable Securities and deliver the Piggy-Back
Registrable Securities pursuant to the terms of this Agreement and the Securities Purchase Agreement.

 

c.
The Company shall use its efforts and take all available steps to have the Registration Statement declared effective by the SEC within
ninety (90) calendar days after the Filing Date (the “Effective Deadline”). If the Registration Statement covering
the Piggy-Back Registrable Securities to be filed by the Company pursuant to Section 2(a) hereof has not become effective by the
Effective Deadline, then it shall constitute an event of default under Section 3.3 of the Note.

 

If
the Registration Statement covering the Piggy-Back Registrable Securities to be filed by the Company pursuant to Section 2(a)
hereof has become effective, and, thereafter, the Holder’s right to sell is suspended, for any reason, then the Company shall pay
the Holder the sum of one percent (1%) of the Purchase Amount plus interest and penalties due to the Holder under the Note for each thirty
(30) calendar day period, pro rata, compounded annually, following the suspension, until such suspension ceases (the “Suspension
Damages”). The Suspension Damages shall continue until the obligation is fulfilled and shall be paid within five (5) business
days after each thirty (30) day period, or portion thereof, until such suspension is released. The Suspension Damages shall be paid,
at the Holder’s option, in cash or shares of the Company’s common stock, par value $0.001, priced at the Conversion Price
(as defined in the Note), or portion thereof. Failure of the Company to make payment within said five (5) business days after each thirty
(30) day period shall be considered a breach of this Agreement and an event of default under Section 3.3 of the Note.

 

    	2

     

    

 

Notwithstanding
the foregoing, the amounts payable by the Company pursuant to this Section 2(c) shall not be payable to the extent any delay in
the effectiveness of the Registration Statement or any suspension of the effectiveness occurs because of an act of, or a failure to act
or to act timely by the Holder or is otherwise solely attributable to the Holder.

 

The
Company acknowledges that its failure to have the Registration Statement become effective by the Effective Deadline or to permit the
suspension of the effectiveness of the Registration Statement, will cause the Holder to suffer irreparable harm and, that damages will
be difficult to ascertain. Accordingly, the Parties agree that it is appropriate to include in this Agreement a provision for liquidated
damages. The Parties acknowledge and agree that the liquidated damages provision set forth in this Section 2(c) represents the
Parties’ good faith effort to quantify such damages and, as such, agree that the form and amount of such liquidated damages are
reasonable and will not constitute a penalty. The payment of liquidated damages shall not relieve the Company from its obligations to
register the Piggy-Back Registrable Securities and deliver the Piggy-Back Registrable Securities pursuant to the terms of this Agreement
and the Securities Purchase Agreement.

 

3.
Related Obligations.

 

At
such time as the Company is obligated to prepare and file a Registration Statement with the SEC pursuant to Section 2(a) hereof,
the Company will use its best efforts to effect the registration of the Piggy-Back Registrable Securities in accordance with the intended
method of disposition thereof and, with respect thereto, the Company shall have the following obligations:

 

a.
The Company shall use its best efforts to cause such Registration Statement relating to the Piggy-Back Registrable Securities to become
effective within ninety (90) calendar days after the Filing Date and shall keep such Registration Statement effective pursuant to Rule
415 under the Securities Act until the date on which the Holder shall have sold all the Piggy-Back Registrable Securities (the “Registration
Period”), which Registration Statement (including any amendments or supplements thereto and prospectuses contained therein)
shall, as of the date thereof, not contain any untrue statement of a material fact or omit to state a material fact required to be stated
therein, or necessary to make the statements therein, in light of the circumstances in which they were made, not misleading.

 

b.
The Company shall prepare and file with the SEC such amendments (including post-effective amendments) and supplements to a Registration
Statement and the prospectus used in connection with such Registration Statement, which prospectus is to be filed pursuant to Rule 424
under the Securities Act, as may be necessary to keep such Registration Statement effective during the Registration Period, and, during
such period, comply with the provisions of the Securities Act with respect to the disposition of all Piggy-Back Registrable Securities
of the Company covered by such Registration Statement until such time as all of such Piggy-Back Registrable Securities shall have been
disposed of in accordance with the intended methods of disposition by the Holder as set forth in such Registration Statement (which shall
be at prevailing market prices, and not fixed prices). In the event the number of shares available under a Registration Statement filed
pursuant to this Agreement is at any time insufficient to cover all of the Piggy-Back Registrable Securities, the Company shall amend
such Registration Statement, or file a new Registration Statement (on the short form available therefor, if applicable), or both, so
as to cover all of the Piggy-Back Registrable Securities, in each case, as soon as practicable, but in any event within thirty (30) calendar
days after the necessity therefor arises (based on the total number of Piggy-Back Registrable Securities). The Company shall use it best
efforts to cause such amendment and/or new Registration Statement to become effective as soon as practicable following the filing thereof.

 

c
The Company shall furnish to the Holder whose Piggy-Back Registrable Securities are included in any Registration Statement and its legal
counsel without charge and upon request (i) promptly after the same is prepared and filed with the SEC at least one copy of such Registration
Statement and any amendment(s) thereto, including financial statements and schedules, all documents incorporated therein by reference
and all exhibits, the prospectus included in such Registration Statement (including each preliminary prospectus) and, with regards to
such Registration Statement(s), any correspondence by or on behalf of the Company to the SEC or the staff of the SEC and any correspondence
from the SEC or the staff of the SEC to the Company or its representatives, (ii) upon the effectiveness of any Registration Statement,
a copy of the prospectus included in such Registration Statement and all amendments and supplements thereto (or such other number of
copies as the Holder may reasonably request) and (iii) such other documents, including copies of any preliminary or final prospectus,
as the Holder may reasonably request from time to time in order to facilitate the disposition of the Piggy-Back Registrable Securities.
The Company filing the documents described in this paragraph through EDGAR shall constitute delivery.

 

    	3

     

    

 

d.
The Company shall use reasonable efforts to (i) register and qualify the Piggy-Back Registrable Securities covered by a Registration
Statement under the applicable securities or “blue sky” laws of such states of the United States as reasonably specified
by the Holder; (ii) prepare and file in those jurisdictions, such amendments (including post-effective amendments) and supplements to
such registrations and qualifications as may be necessary to maintain the effectiveness thereof during the Registration Period; (iii)
take such other actions as may be necessary to maintain such registrations and qualifications in effect at all times during the Registration
Period; and (iv) take all other actions reasonably necessary or advisable to qualify the Piggy-Back Registrable Securities for sale in
such jurisdictions; provided, however, that the Company shall not be required in connection therewith or as a condition thereto to (x)
qualify to do business in any jurisdiction where it would not otherwise be required to qualify but for this Section 3(d), (y)
subject itself to general taxation in any such jurisdiction, or (z) file a general consent to service of process in any such jurisdiction.
The Company shall promptly notify the Holder who holds Piggy-Back Registrable Securities of the receipt by the Company of any notification
with respect to the suspension of the registration or qualification of any of the Piggy-Back Registrable Securities for sale under the
securities or “blue sky” laws of any jurisdiction in the United States or its receipt of actual notice of the initiation
or threatening of any proceeding for such purpose.

 

e.
Upon the happening of any event as a result of which the prospectus included in a Registration Statement, as then in effect, would then
contain an untrue statement of a material fact or omission to state a material fact, which would otherwise be required to be stated therein
or necessary to make the statements therein, in light of the circumstances under which they were made, not misleading; and, as a result,
the prospectus is required to be supplemented or as a result of which the Registration Statement is required to be amended (“Registration
Default”), the Company shall use all diligent efforts to promptly prepare any necessary supplement to such prospectus or amendment
to such Registration Statement and take any other necessary steps to cure the Registration Default, and deliver one (1) copy of such
supplement or amendment to Holder (or such other number of copies as Holder may reasonably request; delivery via EDGAR shall constitute
delivery). Failure to cure the Registration Default within five (5) business days shall result in the Company paying liquidated damages
of one percent (1%) of the Purchase Amount for each thirty (30) calendar day period or portion thereof, beginning on the date of suspension.
The Company shall also promptly notify Holder in writing (i) when a prospectus or any prospectus supplement or post-effective amendment
has been filed, and when a Registration Statement or any post-effective amendment has become effective (notification of such effectiveness
shall be delivered to Holder by facsimile on the same day of such effectiveness and by overnight mail); (ii) in the event the Registration
Statement is no longer effective; or (iii) the Registration Statement is stale for a period of more than five (5) trading days as a result
of the Company’s failure to timely file its financials with the SEC.

 

The
Company acknowledges that its failure to cure the Registration Default within five (5) business days will cause the Holder irreparable
harm, and that damages will be difficult to ascertain. Accordingly, the Parties agree that it is appropriate to include in this Agreement
a provision for liquidated damages. The Parties acknowledge and agree that the liquidated damages provision set forth in this Section
3(e) represents the Parties’ good faith effort to quantify such damages and, as such, agree that the form and amount of such
liquidated damages are reasonable and will not constitute a penalty.

 

It
is the intention of the Parties that interest payable under any of the terms of this Agreement shall not exceed the maximum amount permitted
under any applicable law. If a law, which applies to this Agreement which sets the maximum interest amount, is finally interpreted so
that the interest in connection with this Agreement exceeds the permitted limits, then: (1) any such interest shall be reduced by the
amount necessary to reduce the interest to the permitted limit; and (2) any sums already collected (if any) from the Company which exceed
the permitted limits will be refunded to the Company. The Holder may choose to make this refund by reducing the amount that the Company
owes under this Agreement or by making a direct payment to the Company. If a refund reduces the amount that the Company owes the Holder,
the reduction will be treated as a partial payment. In the event that any provision of this Agreement is held by a court of competent
jurisdiction to be excessive in scope or otherwise invalid or unenforceable, such provision shall be adjusted rather than voided, if
possible, so that it is enforceable to the maximum extent possible, and the validity and enforceability of the remaining provisions of
this Agreement will not in any way be affected or impaired thereby.

 

f.
The Company shall use its best efforts to prevent the issuance of any stop order or other suspension of effectiveness of a Registration
Statement, or the suspension of the qualification of any of the Piggy-Back Registrable Securities for sale in any jurisdiction and, if
such an order or suspension is issued, to obtain the withdrawal of such order or suspension at the earliest possible moment and to notify
the Holder of the issuance of such order and the resolution thereof. The Company will immediately notify the Holder of a proceeding,
or threat of proceeding, the result of which could affect the effectiveness of the registration statement.

i.
The Company shall hold in confidence and not make any disclosure of information concerning the Holder unless (i) disclosure of such information
is necessary to comply with federal or state securities laws, (ii) the disclosure of such information is necessary to avoid or correct
a misstatement or omission in any Registration Statement, (iii) the release of such information is ordered pursuant to a subpoena or
other final, non-appealable order from a court or governmental body of competent jurisdiction, or (iv) such information has been made
generally available to the public other than by disclosure in violation of this Agreement or any other agreement. The Company agrees
that it shall, upon learning that disclosure of such information concerning a Holder is sought in or by a court or governmental body
of competent jurisdiction or through other means, give prompt written notice to the Holder and allow the Holder, at the Holder’s
expense, to undertake appropriate action to prevent disclosure of, or to obtain a protective order for, such information.

 

j.
The Company shall use its best efforts to secure designation and quotation of all the Piggy-Back Registrable Securities covered by any
Registration Statement on the Principal Market, to the extent such is necessary for the Piggy-Back Registrable Securities to trade on
such market. If, despite the Company’s best efforts, the Company is unsuccessful in satisfying this obligation, it shall use its
best efforts to cause all the Piggy-Back Registrable Securities covered by any Registration Statement to be listed on each other national
securities exchange and automated quotation system, if any, on which securities of the same class or series issued by the Company are
then listed, if any, if the listing of such Piggy-Back Registrable Securities is then permitted under the rules of such exchange or system.
If, despite the Company’s best efforts, the Company is unsuccessful in satisfying its obligation in this Section, it will use its
best efforts to secure the inclusion for quotation with the OTC Pink Sheets. The Company shall pay all fees and expenses in connection
with satisfying its obligation under this Section 3(j).

 

k.
The Company shall cooperate with the Holder to facilitate the timely preparation and delivery of book-entry or street name shares(not
bearing any restrictive legend) representing the Piggy-Back Registrable Securities to be offered pursuant to a Registration Statement
and enable such certificates to be in such denominations or amounts, as the case may be, as the Holder may reasonably request and registered
in such names of the Persons who shall acquire such Piggy-Back Registrable Securities from the Holder, as the Holder may request.

 

l.
The Company shall provide a transfer agent for all the Piggy-Back Registrable Securities not later than the Effective Date of the first
Registration Statement filed pursuant hereto.

 

m.
If requested by the Holder, the Company shall (i) as soon as reasonably practical, incorporate in a prospectus supplement or post-effective
amendment such information as Holder reasonably determines should be included therein relating to the sale and distribution of Piggy-Back
Registrable Securities, including, without limitation, information with respect to the Note, Conversion Shares, Warrant, and Warrant
Shares; (ii) make all required filings of such prospectus supplement or post-effective amendment as soon as notified of the matters to
be incorporated in such prospectus supplement or post-effective amendment; and (iii) supplement or make amendments to any Registration
Statement if reasonably requested by Holder.

 

n.
The Company shall use its best efforts to cause the Piggy-Back Registrable Securities covered by the applicable Registration Statement
to be registered with or approved by such other governmental agencies or authorities as may be necessary to consummate the disposition
of such Piggy-Back Registrable Securities.

 

o.
[RESERVED]

 

p.
The Company shall otherwise use its best efforts to comply with all applicable rules and regulations of the SEC in connection with any
registration hereunder.

 

q.
Within five (5) business days after the Registration Statement which includes the Piggy-Back Registrable Securities is declared effective
by the SEC, the Company shall deliver to the Holder confirmation that such Registration Statement has been declared effective by the
SEC.

 

    	5

     

    

 

r.
After the SEC declares the Registration Statement cleared of all comments and the Company’s acceptance of the effectiveness of
the Registration Statement, the Company shall file a prospectus covering the resale of the Piggy-Back Registrable Securities (the “Prospectus”)
within five (5) trading days.

 

s.
The Company shall take all other reasonable actions necessary to expedite and facilitate disposition by the Holder of the Piggy-Back
Registrable Securities pursuant to a Registration Statement.

 

4.
Obligations Of The Holder.

 

a.
At least five (5) calendar days prior to the first anticipated filing date of a Registration Statement, the Company shall notify the
Holder in writing of the information the Company requires from the Holder. The Holder covenants and agrees that, in connection with any
resale of Piggy-Back Registrable Securities by it pursuant to a Registration Statement, it shall comply with the “Plan of Distribution”
section of the current prospectus relating to such Registration Statement, and such “Plan of Distribution” shall include
Holder’s resale of the Piggy-Back Registrable Securities at prevailing market prices (and not fixed prices).

 

b.
The Holder, by the Holder’s acceptance of the Piggy-Back Registrable Securities, agrees to cooperate with the Company as reasonably
requested by the Company in connection with the preparation and filing of any Registration Statement hereunder and in responding to SEC
comments in connection therewith.

 

c.
The Holder agrees that, upon receipt of any notice from the Company of the happening of any event of the kind described in Section
3(f) hereof or the first sentence of Section 3(e) hereof, the Holder will immediately discontinue disposition of Piggy-Back
Registrable Securities pursuant to any Registration Statement(s) covering such Piggy-Back Registrable Securities until Holder’s
receipt of the copies of the supplemented or amended prospectus contemplated by Section 3(f) hereof or the first sentence of Section
3(e) hereof.

 

5.
Expenses Of Registration.

 

All
expenses, including, without limitation, all registration, listing and qualifications fees, printing and accounting fees, and reasonable
fees and disbursements of counsel for the Company shall be paid by, and are the sole obligation of, the Company.

 

6.
Indemnification.

 

In
the event any Piggy-Back Registrable Securities are included in a Registration Statement under this Agreement:

 

a.
To the fullest extent permitted by law, the Company will, and hereby agrees to, indemnify, hold harmless and defend the Holder who holds
such Piggy-Back Registrable Securities, the directors, officers, partners, employees, agents, representatives of, and each Person, if
any, who controls Holder within the meaning of the Securities Act or the Exchange Act) (each, an “Indemnified Person”),
against any losses, claims, damages, liabilities, judgments, fines, penalties, charges, costs, reasonable attorneys’ fees, amounts
paid in settlement or reasonable expenses, joint or several (collectively, “Claims”), incurred in investigating, preparing
or defending any action, claim, suit, inquiry, proceeding, investigation or appeal taken from the foregoing by or before any court or
governmental, administrative or other regulatory agency, body or the SEC, whether pending or threatened, whether or not an indemnified
party is or may be a party thereto (Indemnified Damages”), to which any of them may become subject insofar as such Claims
(or actions or proceedings, whether commenced or threatened, in respect thereof) arise out of or are based upon: (i) any untrue statement
or alleged untrue statement of a material fact in a Registration Statement or any post-effective amendment thereto or in any filing made
in connection with the qualification of the Note under the securities or other “blue sky” laws of any jurisdiction in which
Piggy-Back Registrable Securities are offered (“Blue Sky Filing”), or the omission or alleged omission to state a
material fact required to be stated therein or necessary to make the statements therein, in light of the circumstances under which the
statements therein were made, not misleading, (ii) any untrue statement or alleged untrue statement of a material fact contained in the
final prospectus (as amended or supplemented, if the Company files any amendment thereof or supplement thereto with the SEC) or the omission
or alleged omission to state therein any material fact necessary to make the statements made therein, in light of the circumstances under
which the statements therein were made, not misleading, or (iii) any violation or alleged violation by the Company of the Securities
Act, the Exchange Act, any other law, including, without limitation, any state securities law, or any rule or regulation thereunder relating
to the offer or sale of the Piggy-Back Registrable Securities pursuant to a Registration Statement (the matters in the foregoing clauses
(i) through (iii) being, collectively, “Violations”). Subject to the restrictions set forth in Section 6(c)
hereof with respect to the number of legal counsel, the Company shall reimburse the Holder and each such controlling person, promptly
as such expenses are incurred and are due and payable, for any reasonable legal fees or other reasonable expenses incurred by them in
connection with investigating or defending any such Claim. Notwithstanding anything to the contrary contained herein, the indemnification
agreement contained in this Section 6(a): (i) shall not apply to a Claim arising out of or based upon a Violation committed by
any Indemnified Person or which occurs in reliance upon and in conformity with information furnished in writing to the Company by any
Indemnified Person expressly for use in connection with the preparation of the Registration Statement or any such amendment thereof or
supplement thereto, if such prospectus were timely made available by the Company pursuant to Section 3(c) hereof; (ii) shall not
be available to the extent such Claim is based on (a) a failure of the Holder to deliver or to cause to be delivered the prospectus made
available by the Company or (b) the Indemnified Person’s use of an incorrect prospectus despite being promptly advised in advance
by the Company in writing not to use such incorrect prospectus; and (iii) shall not apply to amounts paid in settlement of any Claim
if such settlement is effected without the prior written consent of the Company, which consent shall not be unreasonably withheld. Such
indemnity shall remain in full force and effect regardless of any investigation made by or on behalf of the Indemnified Person and shall
survive the resale of the Piggy-Back Registrable Securities by the Holder pursuant to the Registration Statement.

b.
Promptly after receipt by an Indemnified Person or Indemnified Party under this Section 6 of notice of the commencement of any
action or proceeding (including any governmental action or proceeding) involving a Claim, such Indemnified Person or Indemnified Party
shall, if a Claim in respect thereof is to be made against any indemnifying party under this Section 6, deliver to the indemnifying
party a written notice of the commencement thereof, and the indemnifying party shall have the right to participate in, and, to the extent
the indemnifying party so desires, jointly with any other indemnifying party similarly noticed, to assume control of the defense thereof
with counsel mutually satisfactory to the indemnifying party and the Indemnified Person or the Indemnified Party, as the case may be;
provided, however, that an Indemnified Person or Indemnified Party shall have the right to retain its own counsel with the fees and expenses
to be paid by the indemnifying party, if, in the reasonable opinion of counsel retained by the indemnifying party, the representation
by such counsel of the Indemnified Person or Indemnified Party and the indemnifying party would be inappropriate due to actual or potential
differing interests between such Indemnified Person or Indemnified Party and any other party represented by such counsel in such proceeding.
The indemnifying party shall pay for only one separate legal counsel for the Indemnified Persons or the Indemnified Parties, as applicable.
Such counsel shall be selected by the Company if the Company is the indemnifying party. The Indemnified Party or Indemnified Person shall
cooperate fully with the indemnifying party in connection with any negotiation or defense of any such action or claim by the indemnifying
party and shall furnish to the indemnifying party all information reasonably available to the Indemnified Party or Indemnified Person
which relates to such action or claim. The indemnifying party shall keep the Indemnified Party or Indemnified Person fully apprised at
all times as to the status of the defense or any settlement negotiations with respect thereto. No indemnifying party shall be liable
for any settlement of any action, claim or proceeding effected without its written consent, provided, however, that the indemnifying
party shall not unreasonably withhold, delay or condition its consent. No indemnifying party shall, without the consent of the Indemnified
Party or Indemnified Person, consent to entry of any judgment or enter into any settlement or other compromise which does not include
as an unconditional term thereof the giving by the claimant or plaintiff to such Indemnified Party or Indemnified Person of a release
from all liability in respect to such Claim. Following indemnification as provided for hereunder, the indemnifying party shall be subrogated
to all rights of the Indemnified Party or Indemnified Person with respect to all third parties, firms or corporations relating to the
matter for which indemnification has been made. The failure to deliver written notice to the indemnifying party within a reasonable time
of the commencement of any such action shall not relieve such indemnifying party of any liability to the Indemnified Person or Indemnified
Party under this Section 6, except to the extent that the indemnifying party is actually prejudiced in its ability to defend such
action.

 

c.
The indemnification required by this Section 6 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 Indemnified Damages are incurred.

 

d.
The indemnity agreements contained herein shall be in addition to (i) any cause of action or similar right of the Indemnified Party or
Indemnified Person against the indemnifying party or others, and (ii) any liabilities the indemnifying party may be subject to pursuant
to the law.

 

    	7

     

    

 

7.
Contribution.

 

To
the extent any indemnification by an indemnifying party is prohibited or limited by law, the indemnifying party agrees to make the maximum
contribution with respect to any amounts for which it would otherwise be liable under Section 6 hereof to the fullest extent permitted
by law; provided, however, that: (i) no contribution shall be made under circumstances where the maker would not have been liable for
indemnification under the fault standards set forth in Section 6 hereof; (ii) no seller of Piggy-Back Registrable Securities guilty
of fraudulent misrepresentation (within the meaning of Section 11(f) of the Securities Act) shall be entitled to contribution from any
seller of Piggy-Back Registrable Securities who was not guilty of fraudulent misrepresentation; and (iii) contribution by any seller
of Piggy-Back Registrable Securities shall be limited in amount to the net amount of proceeds received by such seller from the sale of
such Piggy-Back Registrable Securities.

 

8.
Reports Under The Exchange Act.

 

With
a view to making available to the Holder the benefits of Rule 144 under the Securities Act or any similar rule or regulation of the SEC
that may at any time permit the Investors to sell securities of the Company to the public without registration (“Rule 144”)
the Company agrees to take commercially reasonable efforts to:

 

a.
make and keep public information available, as those terms are understood and defined in Rule 144;

 

b.
file with the SEC in a timely manner all reports and other documents required of the Company under the Securities Act and the Exchange
Act so long as the Company remains subject to such requirements and the filing of such reports and other documents as are required by
the applicable provisions of Rule 144; and

 

c.
furnish to the Holder so long as the Holder owns Piggy-Back Registrable Securities, promptly upon request, (i) a written statement by
the Company that it has complied with the reporting requirements of Rule 144, the Securities Act and the Exchange Act, (ii) a copy of
the most recent annual or quarterly report of the Company and such other reports and documents so filed by the Company, and (iii) such
other information as may be reasonably requested to permit the Investors to sell such securities pursuant to Rule 144 without registration.

registration rights and obligations under this Agreement shall not be assignable.

 

10.

or prospectively), only with the written consent of both the Company and the Holder of the Piggy-Back Registrable Securities. Any amendment
or waiver effected in accordance with this Section 10 shall be binding upon the Holder and the Company.

the same. The addresses for such communications are as set forth on the signature page to this Agreement. Each Party shall provide five
(5) business days prior notice to the other Party of any change in address, phone number or facsimile number.

 

b.
Failure of any Party to exercise any right or remedy under this Agreement or otherwise, or delay by a Party in exercising such right
or remedy, shall not operate as a waiver thereof.

 

c.
This Agreement and all acts and transactions pursuant hereto and the rights and obligations of the Parties hereto shall be governed,
construed and interpreted in accordance with the laws of the State of Delaware, without giving effect to principles of conflicts of law.
The Parties submit to the jurisdiction of the state of New York and federal courts in the borough of Manhattan, New York, and agree that

herewith. Any waiver by the Holder of any breach under this Agreement (a “RRA Breach”) shall not waive or affect any
other RRA Breach, whether such RRA Breach is prior or subsequent thereto and whether of the same or a different type. None of the undertakings,
agreements and covenants of the Company contained in this Agreement, and no RRA Breach, shall be deemed to have been waived by the Holder,
nor may this Agreement be amended, changed or modified, unless such waiver, amendment, change or modification is evidenced by an instrument
in writing specifying such waiver, amendment, change or modification and signed by the Holder.

 

13.
Payment Of Liquidated Damages.

 

With
respect to any liquidated damages or other fees incurred herein by the Company for failure to act in a timely manner, the Holder reserves
the rights to take payment of such amounts in cash or in Common Stock priced at the Conversion Price (as defined in the Note).
