Subsidiaries or by which any property or asset of the Company or any of its 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). Neither the Company nor any of its Subsidiaries is in violation of its Certificate
of Incorporation, By-laws or other organizational documents and neither the Company nor any of its Subsidiaries is in default
(and as of the time of issuance of the Note. no event exists which with notice or lapse of time or both could put the Company
or any of its Subsidiaries in default) under, and neither the Company nor any of its 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 Subsidiaries is a party or by which any property or assets of the Company
or any of its 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 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, the Note, the Security Agreement, the Intercreditor
Agreement, the Irrevocable Transfer Agent Instructions, and the Warrant in accordance with the terms hereof or thereof or to issue
and sell the Note and the Warrant in accordance with the terms hereof and to issue, upon conversion of the Note (only upon an
event of default as described in Section 3 of the Note), Conversion Shares and upon exercise of the Warrant, the Warrant Shares,

obtain pursuant to the preceding sentence have been obtained or effected on or prior to the date hereof, excluding notice filing
on Form D with the SEC, and applicable Blue Sky filings which will be made immediately following the issuance of the Note. If
the Company is listed on the Over-the-Counter Bulletin Board, the OTCQB Market operated by OTC Markets Group, Inc. or any successor
to such markets (collectively, the “OTCBB”), the Company is not in violation of the listing requirements of the OTCBB
and does not reasonably anticipate that the Common Stock will be delisted by the OTCBB in the foreseeable future. The Company
and its Subsidiaries are unaware of any facts or circumstances which might give rise to any of the foregoing.

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
hereinafter referred to herein 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). 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 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 its most recent quarterly report on Form 10-Q filed on May 19, 2016, 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. 

 

i.
Absence of Certain Changes. Since the date of its most recent quarterly report on Form 10-Q, filed on May 19, 2016, there

financial condition, results of operations, prospects or 1934 Act reporting status of the Company or any of its Subsidiaries.

 

j.
Absence of Litigation. 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 Subsidiaries,
threatened against or affecting the Company or any of its 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 Subsidiaries, without regard
to whether it would have a Material Adverse Effect. The Company and its 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 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 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 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 Subsidiaries have taken reasonable security measures to protect the secrecy, confidentiality and value of their Intellectual
Property.

 

l.
No Materially Adverse Contracts, Etc. Neither the Company nor any of its 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 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. The Company and each of its 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 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 loans made to the Company officers and directors and arm’s length transactions

favorable than the Company or any of its Subsidiaries could obtain from third parties and other than the grant of stock options
described in the SEC Documents, none of the officers, directors, or employees of the Company is presently a party to any transaction
with the Company or any of its Subsidiaries (other than for services as employees, officers and directors), including any contract,

is true 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 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 (assuming for this purpose that the Company’s
reports filed under the 1934 Act are being incorporated into an effective registration statement filed by the Company under the
1933 Act).

 

p.

solely in the capacity of an arm’s length purchaser with respect to this Agreement and the transactions contemplated hereby.
The Company further acknowledges that the Buyer is not acting as a financial advisor or fiduciary of the Company (or in any similar
capacity) with respect to this Agreement and the transactions contemplated hereby and any statement made by the Buyer or any of
its respective representatives or agents in connection with this Agreement and the transactions contemplated hereby is not advice

q.
No Integrated Offering. Neither the Company, nor any of its affiliates, nor any person acting on its or their behalf, has

to the Buyer will not be integrated with any other issuance of the Company’s securities (past, current or future) for purposes
of any shareholder approval provisions applicable to the Company or its securities.

 

r.
No Brokers. The Company has taken no action which would give rise to any claim by any person for brokerage commissions,

s.

licenses, permits, easements, variances, exemptions, consents, certificates, approvals and orders necessary to own, lease and
operate its properties and to carry on its business as it is now being conducted (collectively, the “Company Permits”),
and there is no action pending or, to the knowledge of the Company, threatened regarding suspension or cancellation of any of
the Company Permits. Neither the Company nor any of its Subsidiaries is in conflict with, or in default or violation of, any of
the Company Permits, except for any such conflicts, defaults or violations which, individually or in the aggregate, would not
reasonably be expected to have a Material Adverse Effect. Since March 31, 2016, neither the Company nor any of its Subsidiaries
has received any notification with respect to possible conflicts, defaults or violations of applicable laws, except for notices
relating to possible conflicts, defaults or violations, which conflicts, defaults or violations would not have a Material Adverse

t.
Environmental Matters.

 

(i)
There are, to the Company’s knowledge, with respect to the Company or any of its Subsidiaries or any predecessor of the
Company, no past or present violations of Environmental Laws (as defined below), releases of any material into the environment,
actions, activities, circumstances, conditions, events, incidents, or contractual obligations which may give rise to any common
law environmental liability or any liability under the Comprehensive Environmental Response, Compensation and Liability Act of
1980 or similar federal, state, local or foreign laws and neither the Company nor any of its Subsidiaries has received any notice
with respect to any of the foregoing, nor is any action pending or, to the Company’s knowledge, threatened in connection
with any of the foregoing. The term “Environmental Laws” means all federal, state, local or foreign laws relating
to pollution or protection of human health or the environment (including, without limitation, ambient air, surface water, groundwater,
land surface or subsurface strata), including, without limitation, laws relating to emissions, discharges, releases or threatened
releases of chemicals, pollutants contaminants, or toxic or hazardous substances or wastes (collectively, “Hazardous Materials”)
into the environment, or otherwise relating to the manufacture, processing, distribution, use, treatment, storage, disposal, transport
or handling of Hazardous Materials, as well as all authorizations, codes, decrees, demands or demand letters, injunctions, judgments,
licenses, notices or notice letters, orders, permits, plans or regulations issued, entered, promulgated or approved thereunder.

 

(ii)
Other than those that are or were stored, used or disposed of in compliance with applicable law, no Hazardous Materials are contained
on or about any real property currently owned, leased or used by the Company or any of its Subsidiaries, and no Hazardous Materials
were released on or about any real property previously owned, leased or used by the Company or any of its Subsidiaries during
the period the property was owned, leased or used by the Company or any of its Subsidiaries, except in the normal course of the
Company’s or any of its Subsidiaries’ business.

 

(iii)
There are no underground storage tanks on or under any real property owned, leased or used by the Company or any of its Subsidiaries
that are not in compliance with applicable law.

 

u.
Title to Property. The Company and its Subsidiaries have good and marketable title in fee simple to all real property and
good and marketable title to all personal property owned by them which is material to the business of the Company and its Subsidiaries,
in each case free and clear of all liens, encumbrances and defects except for outstanding security interests as have been disclosed
to Buyer, or such as would not have a Material Adverse Effect. Any real property and facilities held under lease by the Company
and its Subsidiaries are held by them under valid, subsisting and enforceable leases with such exceptions as would not have a
Material Adverse Effect.

 

v.
Insurance. The Company and each of its Subsidiaries are insured by insurers of recognized financial responsibility against
such losses and risks and in such amounts as management of the Company believes to be prudent and customary in the businesses
in which the Company and its Subsidiaries are engaged. Neither the Company nor any such Subsidiary has any reason to believe that
it will not be able to renew its existing insurance coverage as and when such coverage expires or to obtain similar coverage from
similar insurers as may be necessary to continue its business 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 coverage, errors and omissions coverage, and commercial general liability coverage.

 

w.
Internal Accounting Controls. The Company and each of its Subsidiaries maintain a system of internal accounting controls
sufficient, in the judgment of the Company’s board of directors, to provide reasonable assurance that (i) transactions are
executed in accordance with management’s general or specific authorizations, (ii) transactions are recorded as necessary
to permit preparation of financial statements in conformity with generally accepted accounting principles and to maintain asset
accountability, (iii) access to assets is permitted only in accordance with management’s general or specific authorization
and (iv) the recorded accountability for assets is compared with the existing assets at reasonable intervals and appropriate action
is taken with respect to any differences.

 

    	 	9	 

     

    

 

x.
Foreign Corrupt Practices. Neither the Company, nor any of its Subsidiaries, nor any director, officer, agent, employee
or other person acting on behalf of the Company or any Subsidiary has, in the course of his actions for, or on behalf of, the
Company, used any corporate funds for any unlawful contribution, gift, entertainment or other unlawful expenses relating to political
activity; made any direct or indirect unlawful payment to any foreign or domestic government official or employee from corporate
funds; violated or is in violation of any provision of the U.S. Foreign Corrupt Practices Act of 1977, as amended, or made any
bribe, rebate, payoff, influence payment, kickback or other unlawful payment to any foreign or domestic government official or
employee.

 

y.
Solvency. The Company (after giving effect to the transactions contemplated by this Agreement) is solvent (i.e.,
its assets have a fair market value in excess of the amount required to pay its probable liabilities on its existing debts as
they become absolute and matured) and currently the Company has no information that would lead it to reasonably conclude that
the Company would not, after giving effect to the transaction contemplated by this Agreement, have the ability to, nor does it
intend to take any action that would impair its ability to, pay its debts from time to time incurred in connection therewith as
such debts mature. The Company’s financial statements for its most recent fiscal year end and interim financial statements
have been prepared assuming the Company will continue as a going concern, which contemplates the realization of assets and the
satisfaction of liabilities in the normal course of business.

 

z.
No Investment Company. The Company is not, and upon the issuance and sale of the Securities as contemplated by this Agreement
will not be an “investment company” required to be registered under the Investment Company Act of 1940 (an “Investment
Company”). The Company is not controlled by an Investment Company.

 

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

 

bb.
No Disqualification Events. None of the Company, any of its predecessors, any affiliated issuer, any director, executive
officer, other officer of the Company participating in the offering hereunder, any beneficial owner of 20% or more of the Company’s
outstanding voting equity securities, calculated on the basis of voting power, nor any promoter (as that term is defined in Rule
405 under the 1933 Act) connected with the Company in any capacity at the time of sale (each, an “Issuer Covered Person”)
is subject to any of the “Bad Actor” disqualifications described in Rule 506(d)(1)(i) to (viii) under the 1933 Act
(a “Disqualification Event”), except for a Disqualification Event covered by Rule 506(d)(2) or (d)(3). The Company
has exercised reasonable care to determine whether any Issuer Covered Person is subject to a Disqualification Event.

 

cc.
Manipulation of Price. The Company has not, and to its knowledge no one acting on its behalf has: (i) taken, directly or
indirectly, any action designed to cause or to result, or that could reasonably be expected to cause or result, in the stabilization
or manipulation of the price of any security of the Company to facilitate the sale or resale of any of the Securities, (ii) sold,
bid for, purchased, or paid any compensation for soliciting purchases of, any of the Securities, or (iii) paid or agreed to pay
to any person any compensation for soliciting another to purchase any other securities of the Company.

 

dd.
Breach of Representations and Warranties by the Company. The Company agrees that if the Company breaches any of the representations
or warranties set forth in this Section 3 and in addition to any other remedies available to the Buyer pursuant to this Agreement,
it will be considered an Event of Default under Section 3.4 of the Note.

the Securities from the registration requirements of the 1933 Act for sale to the Buyer pursuant to this Agreement under applicable
securities or “blue sky” laws of the states of the United States.

 

c.
Use of Proceeds. The Company shall use the proceeds for general working capital purposes and other purposes expressly set

equity or equity equivalent securities, including without limitation any debt, preferred shares or other instrument or security

into any definitive agreement with regard to the foregoing, in each case unless the Company shall have first complied with this
Section 4(d).

 

ii. The
Company shall deliver to the Buyer an irrevocable written notice (the “Offer Notice”) of any proposed or intended
issuance or sale or exchange (the “Offer”) of the securities being offered (the “Offered Securities”)
in a Subsequent Placement, which Offer Notice shall (w) identify and describe the Offered Securities, (x) describe the price (if
it has been definitively determined) and other terms upon which they are to be issued, sold or exchanged, and the number or amount
of the Offered Securities to be issued (if it has been definitively determined), sold or exchanged, (y) identify the persons (if
known) or entities (if known) to which or with which the Offered Securities are to be offered, issued, sold or exchanged and (z)
offer to issue and sell to or exchange with the Buyer all of the Offered Securities (the subscription amount for such aggregate

set forth in this Section 4.d, an Offer Notice is hereby provided to Buyer of the Company’s intention to initiate a private
placement, in the amount of not less than four million and 00/100 dollars ($4,000,000), with the structure of the private placement
anticipated to consist of common stock and attached warrants, immediately following the issuance of this Note. Buyer shall provide

    	 	11	 

     

    

 

e.
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 action or proceeding that may be brought by the Buyer in order to enforce
any right or remedy under this Agreement, the Note, the Pledge Agreement, the Security Agreement, the Intercreditor Agreement,
the Irrevocable Transfer Agent Instructions, and any document, agreement or instrument contemplated thereby. Notwithstanding any
provision to the contrary contained in this Agreement, the Note, the Security Agreement, the Intercreditor Agreement, the Irrevocable
Transfer Agent Instructions, and any document, agreement or instrument contemplated thereby, it is expressly agreed and provided
that the total liability of the Company under this Agreement, the Note, the Security Agreement, the Intercreditor Agreement, the
Irrevocable Transfer Agent Instructions, or any document, agreement or instrument contemplated thereby for payments which under
New York law are in the nature of interest shall not exceed the maximum lawful rate authorized under applicable law (the “Maximum
Rate”), 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 which under New York law in the nature of interest that the Company may be obligated to pay
under this Agreement, the Note, the Security Agreement, the Intercreditor Agreement, the Irrevocable Transfer Agent Instructions,
and any document, agreement or instrument contemplated thereby exceed such Maximum Rate. It is agreed that if the maximum contract
rate of interest allowed by New York law and applicable to this Agreement, the Note, the Security Agreement, the Intercreditor
Agreement, the Irrevocable Transfer Agent Instructions, and any document, agreement or instrument contemplated thereby 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 this Agreement, the Note, the Security Agreement, the Intercreditor Agreement,
the Irrevocable Transfer Agent Instructions, and any document, agreement or instrument contemplated thereby 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 the Buyer with respect to indebtedness evidenced by this Agreement, the
Note, the Pledge Agreement , the Security Agreement, the Intercreditor Agreement, the Irrevocable Transfer Agent Instructions,
and any document, agreement or instrument contemplated thereby, such excess shall be applied by the Buyer to the unpaid principal
balance of any such indebtedness or be refunded to the Company, the manner of handling such excess to be at the Buyer’s
election.

 

f.

withheld: (a) change the nature of its business; (b) sell, divest, acquire, change the structure of any material assets other
than in the ordinary course of business, expressly excluding the sale or license of the Company’s metal-air battery business,
which is not core to the Company’s business; or (c) accept any offers for a variable rate debt transactions (i.e., transactions
where the conversion or exercise price of the security issued by the Company varies based on the market price of the Common Stock).

 

g.

on the OTCBB or any equivalent replacement exchange or electronic quotation system (including but not limited to the Pink Sheets
electronic quotation system) and will comply in all respects with the Company’s reporting, filing and other obligations
under the bylaws or rules of the Financial Industry Regulatory Authority (“FINRA”) and such exchanges, as applicable.

(i) assumes the Company’s obligations hereunder and under the agreements and instruments entered into in connection herewith
and (ii) is a publicly traded corporation whose Common Stock is listed for trading or quotation on the OTCBB, any tier of the

m.
Disclosure of Transactions and Other Material Information. By 9:00 a.m., New York time, on or before the fourth calendar
day following the date this Agreement has been fully executed (and if such day falls on a weekend, then no later than the immediately
following trading day), the Company shall file a Current Report on Form 8-K describing the terms of the transactions contemplated
by this Agreement in the form required by the 1934 Act and attaching this Agreement, the form of Note, the form of Pledge Agreement,
the form of Security Agreement and the form of Warrant (the “8-K Filing”). From and after the filing of the 8-K Filing
with the SEC, the Buyer shall ensure that it is not in possession of any material, nonpublic information received from the Company,
any of its Subsidiaries or any of their respective officers, directors, employees or agents that is not disclosed in the 8-K Filing.
In addition, effective upon the filing of the 8-K Filing, 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, affiliates, employees or agents, on the one hand, and the Buyer or any of its affiliates, on the
other hand, shall terminate.

 

n.
Legal Counsel Opinions. Upon the request of the Buyer from to time to time, the Company shall be responsible (at its cost)
for promptly supplying to the Company’s transfer agent and the Buyer a customary legal opinion letter of its counsel (the
“Legal Counsel Opinion”) to the effect that the resale of the Conversion Shares and the Warrant Shares by the Buyer
or its affiliates, successors and assigns is exempt from the registration requirements of the 1933 Act pursuant to Rule 144 (provided
the requirements of Rule 144 are satisfied and provided the Conversion Shares and the Warrant Shares are not then registered under
the 1933 Act for resale pursuant to an effective registration statement). Should the Company’s legal counsel fail for any
reason to issue the Legal Counsel Opinion, the Buyer may (at the Company’s cost) secure another legal counsel to issue the
Legal Counsel Opinion, and the Company will instruct its transfer agent to accept such opinion.

 

o.
Piggyback Registration Rights. The Company hereby grants to the Buyer the registration rights set forth on Exhibit F
hereto.

 

    	 	13	 

     

    

 

p.
Most Favored Nation. While the Note or any principal amount, interest or fees or expenses due thereunder remain outstanding
and unpaid, the Company shall not enter into any public or private offering of its securities (including securities convertible
into shares of Common Stock) with any individual or entity (an “Other Investor”) that has the effect of establishing
rights or otherwise benefiting such Other Investor in a manner more favorable in any material respect to such Other Investor than
the rights and benefits established in favor of the Buyer by this Agreement, the Note, the Pledge Agreement, the Security Agreement,
the Intercreditor Agreement, the Irrevocable Transfer Agent Instructions, or the Warrant unless, in any such case, the Buyer has
been provided with such rights and benefits pursuant to a definitive written agreement or agreements between the Company and the
Buyer.

 

q.
Subsequent Variable Rate Transactions. From the date hereof until such time as the Buyer no longer holds the Note or any
of the Conversion Shares, the Company shall be prohibited from effecting or entering into an agreement involving a Variable Rate
Transaction. “Variable Rate Transaction” means a transaction in which the Company (i) issues or sells any debt or
equity securities that are convertible into, exchangeable or exercisable for, or include the right to receive, additional shares
of Common Stock either (A) at a conversion price, exercise price or exchange rate or other price that is based upon, and/or varies
with, the trading prices of or quotations for the shares of Common Stock at any time after the initial issuance of such debt or
equity securities or (B) with a conversion, exercise or exchange price that is subject to being reset at some future date after
the initial issuance of such debt or equity security or upon the occurrence of specified or contingent events directly or indirectly
related to the business of the Company or the market for the Common Stock or (ii) enters into any agreement, including, but not
limited to, an equity line of credit, whereby the Company may issue securities at a future determined price. Any Purchaser shall
be entitled to obtain injunctive relief against the Company to preclude any such issuance, which remedy shall be in addition to
any right to collect damages. Notwithstanding the foregoing, and for the avoidance of doubt, the Company may enter into a Variable
Rate Transaction, at its election, provided the closing proceeds of a Variable Rate Transaction are utilized to repay the Note
in full,

 

5.
Transfer Agent Instructions. The Company shall issue irrevocable instructions to its transfer agent to issue certificates,
registered in the name of the Buyer or its nominee, for, upon conversion of the Note, the Conversion Shares (upon the occurrence
of an Event of Default pursuant to Section 3 of the Note) and upon exercise of the Warrant, the Warrant Shares, in such amounts
as specified from time to time by the Buyer to the Company in accordance with the terms thereof (the “Irrevocable Transfer
Agent Instructions”). In the event that the Company proposes to replace its transfer agent, 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 reserved shares of Common Stock in the Reserved
Amount (as defined in the Note)) signed by the successor transfer agent to the Company and the Company. Prior to registration
of the Conversion Shares or the Warrant Shares under the 1933 Act or the date on which the Conversion Shares may be sold pursuant
to Rule 144 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 referred to in this Section 5 will be given by the Company
to its transfer agent and that the Securities shall otherwise be freely transferable on the books and records of the Company as
and to the extent provided in this Agreement and the Note; (ii) it will not direct its transfer agent not to transfer or delay,
impair, and/or hinder its transfer agent in transferring (or issuing)(electronically or in certificated form) any certificate
for Securities to be issued to the Buyer upon conversion of or otherwise pursuant to the Note or upon exercise of or otherwise
pursuant to the Warrant as and when required by the Note, the Warrant and this Agreement; (iii) it will not fail to remove (or
directs its transfer agent not to remove or impairs, delays, and/or hinders its transfer agent from removing) any restrictive
legend (or to withdraw any stop transfer instructions in respect thereof) on any certificate for any Securities issued to the
Buyer upon conversion of or otherwise pursuant to the Note or upon exercise of or otherwise pursuant to the Warrant as and when
required by the Note, the Warrant and this Agreement and (iv) it will provide any required corporate resolutions and issuance
approvals to its transfer agent within one (1) business day of each conversion of the Note or exercise of the Warrant. Nothing
in this Section shall affect in any way the Buyer’s obligations and agreement set forth in Section 2(g) hereof to comply
with all applicable prospectus delivery requirements, if any, upon re-sale of the Securities. If the Buyer provides the Company,
at the cost of the Company, with (i) an opinion of counsel in form, substance and scope customary 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 Rule 144,
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 acknowledges that the remedy at law for a breach
of its obligations under this Section 5 may be inadequate and agrees, in the event of 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.

Payment Set Aside. To the extent that the Company makes a payment or payments to the Buyer hereunder or pursuant to the
Note or the Warrant, 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,

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.

This Note is 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 Borrower and will not impose personal liability upon the holder thereof.

 

The following terms shall apply to
this Note:

 

ARTICLE I. CONVERSION RIGHTS

 

1.1 Conversion Right Upon
Event of Default. The Holder shall have the right, at any time beginning from and after the occurrence of any Event of Default
hereunder and ending on the date of the payment in full of all outstanding Principal Amount and interest under this Note, to
convert all or any portion of the then outstanding and unpaid Principal Amount plus accrued interest (including any Default Interest)
under this Note into fully paid and non-assessable shares of Common Stock, as such Common Stock exists on the Issue Date, or any
shares of capital stock or other securities of the Borrower into which such Common Stock shall hereafter be changed or reclassified,
at the Conversion Price (as defined below) determined as provided herein (a “Conversion”); provided, however,
that in no event shall the Holder be entitled to convert any portion of this Note in excess of that portion of this Note upon conversion
of which the sum of (1) the number of shares of Common Stock beneficially owned by the Holder and its affiliates (other than shares
of Common Stock which may be deemed beneficially owned through the ownership of the unconverted portion of this Note or the unexercised
or unconverted portion of any other security of the Borrower subject to a limitation on conversion or exercise analogous to the
limitations contained herein) and (2) the number of Conversion Shares issuable upon the conversion of the portion of this Note
with respect to which the determination of this proviso is being made, would result in beneficial ownership by the Holder and its
affiliates of more than 4.99% of the then outstanding shares of Common Stock. For purposes of the proviso set forth in the immediately
preceding sentence, beneficial ownership shall be determined in accordance with Section 13(d) of the Securities Exchange Act of
1934, as amended (the “1934 Act”), and Regulations 13D-G thereunder, except as otherwise provided in clause (1) of
such proviso, provided, however, that the limitations on conversion may be waived by the Holder upon, at the election
of the Holder, not less than 61 days’ prior notice to the Borrower, and the provisions of the conversion limitation shall
continue to apply until such 61st day (or such later date, as determined by the Holder, as may be specified in such notice of waiver).
The number of Conversion Shares to be issued upon each conversion of this Note shall be determined by dividing the Conversion Amount
(as defined below) by the applicable Conversion Price then in effect on the date specified in the notice of conversion, in the
form attached hereto as Exhibit A (the “Notice of Conversion”), delivered to the Borrower by the Holder in accordance
with Section 1.4 below; provided that the Notice of Conversion is submitted by facsimile or e-mail (or by other means resulting
in, or reasonably expected to result in, notice) to the Borrower before 4:00 p.m., New York, New York time on such conversion date
(the “Conversion Date”). The term “Conversion Amount” means, with respect to any conversion of this Note,
the sum of (1) the Principal Amount of this Note to be converted in such conversion plus (2) at the Holder’s option,
accrued and unpaid interest, if any, on such Principal Amount at the Interest Rate to the Conversion Date, plus (3) at the
Holder’s option, Default Interest, if any, on the amounts referred to in the immediately preceding clauses (1) and/or (2).

 

    	22

    	 

     

1.2 Conversion Price Upon
Event of Default.

 

(a) Calculation of Conversion
Price. The per share conversion price into which any Principal Amount and interest (including any Default Interest) under this
Note shall be convertible into shares of Common Stock hereunder (the “Conversion Price”) shall be equal to 60% multiplied
by the volume-weighted average price of the Common Stock on the OTCQB (or if not reported, as calculated by the Holder in good
faith) during the thirty (30) consecutive Trading Day period immediately preceding the Trading Day that the Company receives a
Notice of Conversion; and provided, further, however, and notwithstanding the above calculation of the Conversion
Price or any other calculation of Conversion Price pursuant to this Section 1.2, if the closing bid price of the Common Stock is
less than the Conversion Price on the date following the Conversion Date (the “Free Trading Share Receipt Date”) on
which the Holder actually receives from the Company or its transfer agent Conversion Shares issuable pursuant to this Section 1
which are immediately upon receipt unrestricted and freely tradable by the Holder either by way of (A) registration under the 1933
Act or (B) pursuant to Rule 144 under the 1933 Act (or a successor rule) (“Rule 144”), Rule 144A under the 1933 Act
(or a successor rule) (“Rule 144A”) or Regulation S under the 1933 Act (or a successor rule) (“Regulation S”),
then the Conversion Price shall be deemed to have been retroactively adjusted, as of the Conversion Date, to a price equal to 75%
multiplied by the closing bid price of the Common Stock on the Free Trading Shares Receipt Date (the “Free Trading Shares
Receipt Date Conversion Price”), and the Company shall, on the Trading Day following the Free Trading Share Receipt Date,
issue to the Holder additional shares of unrestricted, freely tradable Common Stock equal to the difference between (Y) the number
of Conversion Shares receivable upon conversion of the applicable Conversion Amount at the Conversion Price and (Z) the number
of Conversion Shares receivable upon conversion of the applicable Conversion Amount at the Free Trading Shares Receipt Date Conversion
Price; and provided, further, however, and notwithstanding the above calculation of the Conversion Price, if, prior to the
repayment or conversion of this Note, in the event the Borrower consummates a registered or unregistered primary offering of its
securities for capital raising purposes (a “Primary Offering”), the Holder shall have the right, in its discretion,
to (x) demand repayment in full of an amount equal to any outstanding Principal Amount and interest (including Default Interest)
under this Note as of the closing date of the Primary Offering.

 

(b) Conversion Price
During Major Announcements. Notwithstanding anything contained in Section 1.2(a) to the contrary, in the event the Borrower
(i) makes a public announcement that it intends to be acquired by, consolidate or merge with any other corporation or entity (other
than a merger in which the Borrower is the surviving or continuing corporation and its capital stock is unchanged) or sell or transfer
all or substantially all of the assets of the Borrower or (ii) any person, group or entity (including the Borrower) publicly announces
a tender offer to purchase 50% or more of the Common Stock (or any other takeover scheme) (any such transaction referred to in
clause (i) or (ii) being referred to herein as a “Change in Control” and the date of the announcement referred to in
clause (i) or (ii) is being referred to herein as the “Announcement Date”), then the Conversion Price shall, effective
upon the Announcement Date and continuing through the Adjusted Conversion Price Termination Date (as defined below), be equal to
the lower of (x) the Conversion Price and (y) a 25% discount to the Acquisition Price (as defined below). From and after the Adjusted
Conversion Price Termination Date, the Conversion Price shall be determined as set forth in Section 1.2(a). For purposes hereof,
“Adjusted Conversion Price Termination Date” shall mean, with respect to any proposed Change in Control for which a
public announcement as contemplated by this Section 1.2(b) has been made, the date upon which the Borrower (in the case of clause
(i) above) or the person, group or entity (in the case of clause (ii) above) consummates or publicly announces the termination
or abandonment of the proposed Change in Control which caused this Section 1.2(b) to become operative. For purposes hereof, “Acquisition
Price” shall mean a price per share of Common Stock derived by dividing (x) the total consideration (in cash, equity, earn-out
or similar payments or otherwise) paid or to be paid to the Borrower or its shareholders in the Change in Control transaction by
(y) the number of authorized shares of Common Stock outstanding as of the business day prior to the Announcement Date.

 

    	23

    	 

     

1.3 Authorized and Reserved
Shares. The Borrower covenants that during the period the conversion right exists, the Borrower will reserve from its authorized
and unissued Common Stock a sufficient number of shares, free from preemptive rights, to provide for the issuance of a number of
Conversion Shares equal to the greater of: (a) 5,000,000 shares of Common Stock or (b) the sum of (i) the number of Conversion
Shares issuable upon the full conversion of this Note (assuming no payment of Principal Amount or interest) as of any issue date
(taking into consideration any adjustments to the Conversion Price pursuant to Section 2 hereof or otherwise) multiplied by
(ii) five (5) (the “Reserved Amount”). The Reserved Amount shall be recalculated each month and the Company shall notify
its transfer agent and the Holder in writing by the first day of the following month of the new Reserved Amount. In the event that
the Borrower shall be unable to reserve the entirety of the Reserved Amount (the “Reserve Amount Failure”), the Borrower
shall promptly take all actions necessary to increase its authorized share capital to accommodate the Reserved Amount (the “Authorized
Share Increase”), including without limitation, all board of directors actions and approvals and promptly (but no less than
60 days following the calling and holding a special meeting of its shareholders no more than 60 days following the Reserve Amount
Failure to seek approval of the Authorized Share Increase via the solicitation of proxies. Notwithstanding the foregoing, in no
event shall the Reserved Amount be lower than the initial Reserved Amount, regardless of any prior conversions. The Borrower represents
that upon issuance, the Conversion Shares will be duly and validly issued, fully paid and non-assessable. In addition, if the Borrower
shall issue any securities or make any change to its capital structure which would change the number of Conversion Shares into
which this Note shall be convertible at the then current Conversion Price, the Borrower shall at the same time make proper provision
so that thereafter there shall be a sufficient number of shares of Common Stock authorized and reserved, free from preemptive rights,
for conversion of this Note. The Borrower (i) acknowledges that it has irrevocably instructed its transfer agent to issue certificates
for the Conversion Shares or instructions to have the Conversion Shares issued as contemplated by Section 1.4(f) hereof, and (ii)
agrees that its issuance of this Note shall constitute full authority to its officers and agents who are charged with the duty
of executing stock certificates or cause the Company to electronically issue shares of Common Stock to execute and issue the necessary
certificates for the Conversion Shares or cause the Conversion Shares to be issued as contemplated by Section 1.4(f) hereof in
accordance with the terms and conditions of this Note.

 

If, at any time the Borrower
does not maintain the Reserved Amount it will be considered an Event of Default under this Note.

 

1.4 Method
of Conversion Upon Event of Default.

 

(a) Mechanics of Conversion.
This Note may be converted by the Holder in whole or in part, on any Trading Day from and after the occurrence of any Event of
Default hereunder and ending on the date of the payment in full of all outstanding Principal Amount and interest under this Note,
by submitting to the Borrower a Notice of Conversion (by facsimile, e-mail or other reasonable means of communication dispatched
on the Conversion Date prior to 4:00 p.m., New York, New York time). Any Notice of Conversion submitted after 4:00 p.m., New York,
New York time, shall be deemed to have been delivered and received on the next Trading Day.

 

(b) Surrender of Note
Upon Conversion. Notwithstanding anything to the contrary set forth herein, upon conversion of this Note in accordance with
the terms hereof, the Holder shall not be required to physically surrender this Note to the Borrower unless the entire unpaid Principal
Amount is so converted. The Holder and the Borrower shall maintain records showing the Principal Amount so converted and the dates
of such conversions or shall use such other method, reasonably satisfactory to the Holder and the Borrower, so as not to require
physical surrender of this Note upon each such conversion. In the event of any dispute or discrepancy, such records of the Borrower
shall, prima facie, be controlling and determinative in the absence of any error. Notwithstanding the foregoing, if any
portion of this Note is converted as aforesaid, the Holder may not transfer this Note unless the Holder first physically surrenders
this Note to the Borrower, whereupon the Borrower will forthwith issue and deliver upon the order of the Holder a new Note of like
tenor, registered as the Holder (upon payment by the Holder of any applicable transfer taxes) may request, representing in the
aggregate the remaining unpaid Principal Amount of this Note. The Holder and any assignee, by acceptance of this Note, acknowledge
and agree that, by reason of the provisions of this paragraph, following conversion of a portion of this Note, the unpaid and unconverted
Principal Amount of this Note represented by this Note may be less than the amount stated on the face hereof.

 

(c) Payment of Taxes.
The Borrower shall not be required to pay any tax which may be payable in respect of any transfer involved in the issue and delivery
of shares of Common Stock or other securities or property on conversion of this Note in a name other than that of the Holder (or
in street name), and the Borrower shall not be required to issue or deliver any such shares or other securities or property unless
and until the person or persons (other than the Holder or the custodian in whose street name such shares are to be held for the
Holder’s account) requesting the issuance thereof shall have paid to the Borrower the amount of any such tax or shall have
established to the satisfaction of the Borrower that such tax has been paid.

 

    	24

    	 

     

(d) Delivery of Common
Stock Upon Conversion. Upon receipt by the Borrower from the Holder of a facsimile transmission or e-mail or overnight FedEx
of a Notice of Conversion meeting the requirements for conversion as provided in this Section 1.4, the Borrower shall issue and
deliver or cause to be issued and delivered to or upon the order of the Holder certificates for the Conversion Shares (or cause
the electronic delivery of the Conversion Shares as contemplated by Section 1.4(f) hereof) within two (2) Trading Days after such
receipt (the “Deadline”) (and, solely in the case of conversion of the entire unpaid Principal Amount and interest
(including any Default Interest) under this Note, surrender of this Note). If the Company shall fail for any reason or for no reason
to issue to the Holder on or prior to the Deadline a certificate for the number of Conversion Shares or to which the Holder is
entitled hereunder and register such Conversion Shares on the Company’s share register or to credit the Holder’s balance
account with DTC (as defined below) for such number of Conversion Shares to which the Holder is entitled upon the Holder’s
conversion of this Note (a “Conversion Failure”), then, in addition to all other remedies available to the Holder,
(i) the Company shall pay in cash to the Holder on each day after the Deadline and during such Conversion Failure an amount equal
to 2.0% of the product of (A) the sum of the number of Conversion Shares not issued to the Holder on or prior to the Deadline and
to which the Holder is entitled and (B) the closing sale price of the Common Stock on the Trading Day immediately preceding the
last possible date which the Company could have issued such Conversion Shares to the Holder without violating this Section 1.4(d);
and (ii) the Holder, upon written notice to the Company, may void its Notice of Conversion with respect to, and retain or have
returned, as the case may be, any portion of this Note that has not been converted pursuant to such Notice of Conversion; provided
that the voiding of an Notice of Conversion shall not affect the Company’s obligations to make any payments which have accrued
prior to the date of such notice. In addition to the foregoing, if on or prior to the Deadline the Company shall fail to issue
and deliver a certificate to the Holder and register such Conversion Shares on the Company’s share register or credit the
Holder’s balance account with DTC for the number of Conversion Shares to which the Holder is entitled upon the Holder’s
exercise hereunder or pursuant to the Company’s obligation pursuant to clause (ii) below, and if on or after such Trading
Day the Holder purchases (in an open market transaction or otherwise) shares of Common Stock to deliver in satisfaction of a sale
by the Holder of shares of Common Stock issuable upon such exercise that the Holder anticipated receiving from the Company, then
the Company shall, within three (3) Trading Days after the Holder’s request and in the Holder’s discretion, either
(i) pay cash to the Holder in an amount equal to the Holder’s total purchase price (including brokerage commissions and other
reasonable and customary out-of-pocket expenses, if any) for the shares of Common Stock so purchased (the “Buy-In Price”),
at which point the Company’s obligation to deliver such certificate (and to issue such Conversion Shares) or credit such
Holder’s balance account with DTC for such Conversion Shares shall terminate, or (ii) promptly honor its obligation to deliver
to the Holder a certificate or certificates representing such Conversion Shares or credit such Holder’s balance account with
DTC and pay cash to the Holder in an amount equal to the excess (if any) of the Buy-In Price over the product of (A) such number
of shares of Common Stock, times (B) the closing sales price of the Common Stock on the date of exercise. 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 the Conversion Shares (or to electronically deliver such Conversion Shares) upon the conversion of this Note as required
pursuant to the terms hereof.

 

(e) Obligation of Borrower
to Deliver Common Stock. Upon receipt by the Borrower of a Notice of Conversion, the Holder shall be deemed to be the holder
of record of the Conversion Shares issuable upon such conversion, the outstanding Principal Amount and the amount of accrued and
unpaid interest (including any Default Interest) under this Note shall be reduced to reflect such conversion, and, unless the Borrower
defaults on its obligations under this Article I, all rights with respect to the portion of this Note being so converted shall
forthwith terminate except the right to receive the Common Stock or other securities, cash or other assets, as herein provided,
on such conversion. If the Holder shall have given a Notice of Conversion as provided herein, the Borrower’s obligation to
issue and deliver the certificates for the Conversion Shares (or cause the electronic delivery of the Conversion Shares as contemplated
by Section 1.4(f) hereof) shall be absolute and unconditional, irrespective of the absence of any action by the Holder to enforce
the same, any waiver or consent with respect to any provision thereof, the recovery of any judgment against any person or any action
to enforce the same, any failure or delay in the enforcement of any other obligation of the Borrower to the holder of record, or
any setoff, counterclaim, recoupment, limitation or termination, or any breach or alleged breach by the Holder of any obligation
to the Borrower, and irrespective of any other circumstance which might otherwise limit such obligation of the Borrower to the
Holder in connection with such conversion. The Conversion Date specified in the Notice of Conversion shall be the Conversion Date
so long as the Notice of Conversion is received by the Borrower before 6:00 p.m., New York, New York time, on such date.

 

    	25

    	 

     

(f) Delivery of Conversion
Shares by Electronic Transfer. In lieu of delivering physical certificates representing the Conversion Shares issuable upon
conversion hereof, provided the Borrower is participating in the Depository Trust Company (“DTC”) Fast Automated Securities
Transfer or Deposit/Withdrawal at Custodian programs, upon request of the Holder and its compliance with the provisions contained
in Section 1.1 and in this Section 1.4, the Borrower shall use its best efforts to cause its transfer agent to electronically transmit
the Conversion Shares issuable upon conversion hereof to the Holder by crediting the account of Holder’s Prime Broker with
DTC through its Deposit Withdrawal Agent Commission system.

 

1.5 Concerning the Shares.
The Conversion Shares issuable upon conversion of this Note may not be sold or transferred unless (i) such shares are sold pursuant
to an effective registration statement under the 1933 Act or (ii) the Borrower or its transfer agent shall have been furnished
with an opinion of counsel (which opinion shall be the Legal Counsel Opinion (as defined in the Purchase Agreement)) to the effect
that the shares to be sold or transferred may be sold or transferred pursuant to an exemption from such registration or (iii) such
shares are sold or transferred pursuant to Rule 144, Rule 144A or Regulation S or (iv) such shares are transferred to an “affiliate”
(as defined in Rule 144) of the Borrower who agrees to sell or otherwise transfer the shares only in accordance with this Section
1.5 and who is an Accredited Investor (as defined in the Purchase Agreement). Except as otherwise provided in the Purchase Agreement
(and subject to the removal provisions set forth below), until such time as the Conversion Shares have been registered under the
1933 Act or otherwise may be sold pursuant to Rule 144, Rule 144A or Regulation S without any restriction as to the number of securities
as of a particular date that can then be immediately sold, each certificate for the Conversion Shares that has not been so included
in an effective registration statement or that has not been sold pursuant to an effective registration statement or an exemption
that permits removal of the legend, shall bear a legend substantially in the following form, as appropriate:

 

“NEITHER THE ISSUANCE AND SALE
OF THE SECURITIES REPRESENTED BY THIS CERTIFICATE NOR THE SECURITIES INTO WHICH THESE SECURITIES ARE 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 MAY BE THE LEGAL COUNSEL OPINION (AS DEFINED IN THE PURCHASE AGREEMENT)),
IN A GENERALLY ACCEPTABLE FORM, THAT REGISTRATION IS NOT REQUIRED UNDER SAID ACT OR (II) UNLESS SOLD PURSUANT TO RULE 144, RULE
144A OR REGULATION S 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 to the Holder a certificate for the applicable Conversion Shares without such legend
upon which it is stamped or (as requested by the Holder) issue the applicable Conversion Shares by electronic delivery by crediting
the account of such holder’s broker with DTC, if, unless otherwise required by applicable state securities laws: (a) such
Conversion Shares are registered for sale under an effective registration statement filed under the 1933 Act or otherwise may be
sold pursuant to Rule 144, Rule 144A or Regulation S 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 Holder provides the Legal Counsel Opinion (as contemplated by
and in accordance with Section 4(m) of the Purchase Agreement) to the effect that a public sale or transfer of such Conversion
Shares 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 Holder agrees to sell all Conversion Shares, 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 Holder with respect to the transfer of Conversion Shares pursuant to an
exemption from registration, such as Rule 144, Rule 144A or Regulation S, at the Deadline, notwithstanding that the conditions
of Rule 144, Rule 144A or Regulation S, as applicable, have been met, it will be considered an Event of Default under this Note.

 

    	26

    	 

     

1.6 Effect of Certain Events.

 

(a) Effect of Merger,
Consolidation, Etc. At the option of the Holder, the sale, conveyance or disposition of all or substantially all of the assets
of the Borrower, or the consolidation, merger or other business combination of the Borrower with or into any other Person (as defined
below) or Persons when the Borrower is not the survivor shall either: (i) be deemed to be an Event of Default (as defined in Article
III) pursuant to which the Borrower shall be required to pay to the Holder upon the consummation of and as a condition to such
transaction an amount equal to the Default Amount (defined in Section 3.21) or (ii) be treated pursuant to Section 1.6(b) hereof.
“Person” shall mean any individual, corporation, limited liability company, partnership, association, trust or other
entity or organization.

 

(b) Adjustment Due to
Merger, Consolidation, Etc. If, at any time when this Note is issued and outstanding and prior to conversion of all of this
Note, there shall be any merger, consolidation, exchange of shares, recapitalization, reorganization, or other similar event, as
a result of which shares of Common Stock of the Borrower shall be changed into the same or a different number of shares of another
class or classes of stock or securities of the Borrower or another entity, or in case of any sale or conveyance of all or substantially
all of the assets of the Borrower other than in connection with a plan of complete liquidation of the Borrower, then the Holder
of this Note shall thereafter have the right to receive upon conversion of this Note, upon the basis and upon the terms and conditions
specified herein and in lieu of the shares of Common Stock immediately theretofore issuable upon conversion, such stock, securities
or assets which the Holder would have been entitled to receive in such transaction had this Note been converted in full immediately
prior to such transaction (without regard to any limitations on conversion set forth herein), and in any such case appropriate
provisions shall be made with respect to the rights and interests of the Holder of this Note to the end that the provisions hereof
(including, without limitation, provisions for adjustment of the Conversion Price and of the number of shares issuable upon conversion
of the Note) shall thereafter be applicable, as nearly as may be practicable in relation to any securities or assets thereafter
deliverable upon the conversion hereof. The Borrower shall not effectuate any transaction described in this Section 1.6(b) unless
(a) it first gives, to the extent practicable, at least thirty (30) days prior written notice (but in any event at least fifteen
(15) days prior written notice) of the record date of the special meeting of shareholders to approve, or if there is no such record
date, the consummation of, such merger, consolidation, exchange of shares, recapitalization, reorganization or other similar event
or sale of assets (during which time the Holder shall be entitled to convert this Note) and (b) the resulting successor or acquiring
entity (if not the Borrower) assumes by written instrument the obligations of this Section 1.6(b). The above provisions shall similarly
apply to successive consolidations, mergers, sales, transfers or share exchanges.

 

(c) Adjustment Due to
Distribution. If the Borrower shall declare or make any distribution of its assets (or rights to acquire its assets) to holders
of Common Stock as a dividend, stock repurchase, by way of return of capital or otherwise (including any dividend or distribution
to the Borrower’s shareholders in cash or shares (or rights to acquire shares) of capital stock of a subsidiary (i.e., a
spin-off)) (a “Distribution”), then the Holder of this Note shall be entitled, upon any conversion of this Note after
the date of record for determining shareholders entitled to such Distribution, to receive the amount of such assets which would
have been payable to the Holder with respect to the shares of Common Stock issuable upon such conversion had such Holder been the
holder of such shares of Common Stock on the record date for the determination of shareholders entitled to such Distribution.

 

(d) Purchase Rights.
If, at any time when all or any portion of this Note is issued and outstanding, the Borrower issues any convertible securities
or rights to purchase stock, warrants, securities or other property (the “Purchase Rights”) pro rata to the record
holders of any class of Common Stock, then the Holder of this Note will be entitled to acquire, in cash and upon the terms applicable
to such Purchase Rights, the aggregate Purchase Rights which such Holder could have acquired if such Holder had held the number
of shares of Common Stock acquirable upon complete conversion of this Note (without regard to any limitations on conversion contained
herein) 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 Common Stock are to be determined for the grant, issue or sale
of such Purchase Rights. For the avoidance of doubt, notice is hereby provided that the Borrower will be undertaking a private
placement of securities (the “Private Placement”) following the issuance of this Note. Holders may exercise its Purchase
Rights with respect to the Private Placement by notifying the Borrower in writing of its firm intention to participate with a cash
investment in the Private Placement, including the amount of its participation, pro rata to the record holders of Common Stock
of Borrower.

 

    	27

    	 

     

(e) Dilutive Issuance.
If the Borrower, at any time while this Note or any amounts due hereunder are outstanding, issues, sells or grants (or has issued,
sold or granted as of the Issue Date, as the case may be) any option to purchase, or sells or grants any right to reprice, or otherwise
disposes of, or issues (or has sold or issued, as the case may be, or announces any sale, grant or any option to purchase or other
disposition), any Common Stock or other securities convertible into, exercisable for, or otherwise entitle any person or entity
the right to acquire, shares of Common Stock (including, without limitation, upon conversion of any convertible notes or warrants
outstanding as of or following the Issue Date, but expressly excluding any outstanding options to purchase shares of common stock
pursuant to the Company’s 2014 Equity Incentive Plan in existence as of the date of issuance of this Note), in each or any
case at an effective price per share that is lower than (a) the then Conversion Price or (b) in the event that any such issuance,
sale or grant occurs prior to the occurrence of an Event of Default, the initial Conversion Price following the occurrence of an
Event of Default (such lower price in either case, the “Base Conversion Price” and such issuances in either case, collectively,
a “Dilutive Issuance”) (it being agreed that if the holder of the Common Stock or other securities so issued shall
at any time, whether by operation of purchase price adjustments, reset provisions, floating conversion, exercise or exchange prices
or otherwise, or due to warrants, options or rights per share which are issued in connection with such issuance, be entitled to
receive shares of Common Stock at an effective price per share that is lower than the Conversion Price, such issuance shall be
deemed to have occurred for less than the Conversion Price on such date of the Dilutive Issuance), then the Conversion Price shall
be reduced to a price equal to the Base Conversion Price. If the Company enters into a Variable Rate Transaction, despite the prohibition
set forth in the Purchase Agreement, the Company shall be deemed to have issued Common Stock or Common Stock Equivalents at the
lowest possible price per share at which such securities could be issued in connection with such Variable Rate Transaction. Such
adjustment shall be made whenever such Common Stock or other securities are issued. Notwithstanding the foregoing, no adjustment
will be made under this Section 1.6(e) in respect of an Exempt Issuance. In the event of an issuance of securities involving multiple
tranches or closings, any adjustment pursuant to this Section 1.6(e) shall be calculated as if all such securities were issued
at the initial closing.

 

An “Exempt Issuance”
shall mean the issuance of (a) shares of Common Stock or other securities to employees, officers or directors of the Company pursuant
to the Company’s 2014 Equity Incentive Plan; (b) securities issued pursuant to a merger, consolidation, acquisition or similar
business combination approved by a majority of the disinterested directors of the Company, provided that any such issuance shall
only be to a Person (or to the equityholders of a Person) which is, itself or through its subsidiaries, an operating company or
an owner of an asset in a business synergistic with the business of the Company and shall provide to the Company additional benefits
in addition to the investment of funds, but shall not include a transaction in which the Company is issuing securities primarily
for the purpose of raising capital or to an entity whose primary business is investing in securities; (c) securities issued pursuant
to any equipment loan or leasing arrangement, real property leasing arrangement or debt financing from a bank or similar financial
institution approved by a majority of the disinterested directors of the Company; or (d) issued in the Private Placement in an
amount sufficient to repay in full all of the Notes.

 

(f) Notice of Adjustments.
Upon the occurrence of each adjustment or readjustment of the Conversion Price as a result of the events described in this Section
1.6, the Borrower, at its expense, shall promptly compute such adjustment or readjustment and prepare and furnish to the Holder
a certificate setting forth such adjustment or readjustment and showing in detail the facts upon which such adjustment or readjustment
is based. The Borrower shall, upon the written request at any time of the Holder, furnish to such Holder a like certificate setting
forth (i) such adjustment or readjustment, (ii) the Conversion Price at the time in effect and (iii) the number of shares of Common
Stock and the amount, if any, of other securities or property which at the time would be received upon conversion of the Note.

 

1.7 Trading Market Limitations.
Unless permitted by the applicable rules and regulations of the principal securities market on which the Common Stock is then listed
or traded, in no event shall the Borrower issue upon conversion of or otherwise pursuant to this Note more than the maximum number
of shares of Common Stock that the Borrower can issue pursuant to any rule of the principal United States securities market on
which the Common Stock is then traded (the “Maximum Share Amount”), which shall be 4.99% of the total shares outstanding
on the Initial Closing Date (as defined in the Purchase Agreement), subject to equitable adjustment from time to time for stock
splits, stock dividends, combinations, capital reorganizations and similar events relating to the Common Stock occurring after
the Issue Date. Once the Maximum Share Amount has been issued, if the Borrower fails to satisfy any prohibitions under applicable
law or the rules or regulations of any stock exchange, interdealer quotation system or other self-regulatory organization with
jurisdiction over the Borrower or any of its securities on the Borrower’s ability to issue shares of Common Stock in excess
of the Maximum Share Amount, in lieu of any further right to convert this Note, this will be considered an Event of Default under
Section 3.3 of the Note.

 

    	28

    	 

     

1.8 Status as Shareholder.
Upon submission of a Notice of Conversion by a Holder, (i) the Conversion Shares covered thereby (other than the Conversion Shares,
if any, which cannot be issued because their issuance would exceed such Holder’s allocated portion of the Reserved Amount
or Maximum Share Amount) shall be deemed converted into shares of Common Stock and (ii) the Holder’s rights as a Holder of
such converted portion of this Note shall cease and terminate, excepting only the right to receive certificates for such shares
of Common Stock and to any remedies provided herein or otherwise available at law or in equity to such Holder because of a failure
by the Borrower to comply with the terms of this Note. Notwithstanding the foregoing, if a Holder has not received certificates
for all shares of Common Stock prior to the tenth (10th) business day after the expiration of the Deadline with respect to a conversion
of any portion of this Note for any reason, then (unless the Holder otherwise elects to retain its status as a holder of Common
Stock by so notifying the Borrower) the Holder shall regain the rights of a Holder of this Note with respect to such unconverted
portions of this Note and the Borrower shall, as soon as practicable, return such unconverted Note to the Holder or, if the Note
has not been surrendered, adjust its records to reflect that such portion of this Note has not been converted. In all cases, the
Holder shall retain all of its rights and remedies for the Borrower’s failure to convert this Note.

 

1.9 Prepayment. Notwithstanding
anything to the contrary contained in this Note, at any time prior to or as of (but not following) the Maturity Date, the Borrower
shall have the right, exercisable on not less than one (1) Trading Day prior written notice to the Holder of the Note, to prepay
the outstanding Principal Amount of this note together with accrued interest (including any Default Interest) then due under this
Note, in whole or in part, in accordance with this Section 1.9. Any notice of prepayment hereunder (an “Optional Prepayment
Notice”) shall be delivered to the Holder of the Note at its registered addresses or via facsimile or email and shall state:
(1) that the Borrower is exercising its right to prepay the Note, and (2) the date of prepayment which shall be not more than three
(3) Trading Days from the date of the Optional Prepayment Notice. On the date fixed for prepayment (the “Optional Prepayment
Date”), the Borrower shall make payment of the Optional Prepayment Amount (as defined below) to or upon the order of the
Holder as specified by the Holder in writing to the Borrower at least one (1) business day prior to the Optional Prepayment Date.
If the Borrower exercises its right to prepay the Note, the Borrower shall make payment to the Holder of an amount in cash (the
“Optional Prepayment Amount”) equal to the sum of: (w) 115% multiplied by the Principal Amount plus (x) accrued
and unpaid interest on the Principal Amount to the Optional Prepayment Date plus (y) Default Interest, if any, on the amounts
referred to in clauses (w) and (x).

 

1.10 Repayment from Financing
Proceeds. While any portion of the outstanding Principal Amount and interest (including Default Interest) under this Note are
due and owning, if the Company receives cash proceeds from any source or series of related or unrelated sources, including but
not limited to, from the issuance of equity or debt (including but not limited to the Private Placement), the conversion of outstanding
warrants of the Borrower, the issuance of securities pursuant to an equity line of credit of the Borrower or the sale or divestiture
of the Company’s metal-air battery business or any other assets, the Borrower shall, within three (3) business days of Borrower’s
receipt of such proceeds, inform the Holder of such receipt, following which the Holder shall have the right in its sole discretion
to require the Borrower to immediately apply all or any portion of such proceeds to repay all or any portion of the outstanding
Principal Amount of this note together with accrued interest (including any Default Interest) then due under this Note. Failure
of the Borrower to comply with this provision shall constitute an Event of Default. In the event that such proceeds are received
by the Holder on or prior to the Maturity Date, the required prepayment shall be subject to the terms of Section 1.9 herein.

2.6 Advances and Loans;

rights and privileges, and become or remain, and cause each of its Subsidiaries (other than dormant Subsidiaries that have no or

divest, acquire or change the structure of any material assets other than in the ordinary course of business or (ii) solicit any

or Bylaws, or through any reorganization, transfer of assets, consolidation, merger, scheme of arrangement, 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

ARTICLE III. EVENTS OF DEFAULT

 

It shall be considered

3.10, 3.11, 3.14, 3.16, 3.17, 3.18, 3.19 or 3.20 below, the Borrower shall have five (5) business days to cure such Event of Default
unless a lesser number of days is required pursuant to the provisions of this Article III:

or Interest. The Borrower fails to pay the Principal Amount hereof or interest thereon when due on this Note, whether at maturity,
upon acceleration or otherwise.

 

3.2 Conversion and the

of this Note, (ii) fails to transfer or cause its transfer agent to transfer (issue) (electronically or in certificated form) any
certificate for the Conversion Shares issuable to the Holder upon conversion of or otherwise pursuant to this Note as and when
required by this Note, or (iii) the Borrower directs its transfer agent not to transfer or delays, impairs, and/or hinders its
transfer agent in transferring (or issuing) (electronically or in certificated form) any certificate for the Conversion Shares
issuable to the Holder upon conversion of or otherwise pursuant to this Note as and when required by this Note, or fails to remove
(or directs its transfer agent not to remove or impairs, delays, and/or hinders its transfer agent from removing) any restrictive
legend (or to withdraw any stop transfer instructions in respect thereof) on any certificate for any Conversion Shares issued to
the Holder upon conversion of or otherwise pursuant to this Note as and when required by this Note (or makes any written announcement,
statement or threat that it does not intend to honor the obligations described in this paragraph) and any such failure shall continue
uncured (or any written announcement, statement or threat not to honor its obligations shall not be rescinded in writing) for three
(3) business days after the Holder shall have delivered a Notice of Conversion. It is an obligation of the Borrower to remain current
in its obligations to its transfer agent. It shall be an Event of Default of this Note, if a conversion of this Note is delayed,
hindered or frustrated due to a balance owed by the Borrower to its transfer agent. If at the option of the Holder, the Holder
advances any funds to the Borrower’s transfer agent in order to process a conversion, such advanced funds shall be paid by
the Borrower to the Holder within forty eight (48) hours of a demand from the Holder.

will have) a material adverse effect on the rights of the Holder with respect to this Note or the Purchase Agreement.

 

3.5 Receiver or Trustee.
The Borrower or any subsidiary of the Borrower shall make an assignment for the benefit of creditors, or apply for or consent to

3.11Cessation of Operations.
Any cessation of operations by Borrower or Borrower admits it is otherwise generally unable to pay its debts as such debts become
due, provided, however, that any disclosure of the Borrower’s ability to continue as a “going concern” shall
not be an admission that the Borrower cannot pay its debts as they become due.

 

3.12 Maintenance of Assets.
The failure by Borrower to maintain any material intellectual property rights, personal, real property or other assets which are
necessary to conduct its business (whether now or in the future).

Restatement. The restatement of any financial statements filed by the Borrower with the SEC for any date or period from two
years prior to the Issue Date of this Note and until this Note is no longer outstanding, if the result of such restatement would,

The declaration of an event of default by any lender or other extender of credit to the Company under any notes, loans, agreements

3.21 Rights and Remedies
Upon an Event of Default. Subject to applicable cure periods specifically provided for herein, upon the occurrence and during
the continuation of any Event of Default specified in this Article III, exercisable through the delivery of written notice to the
Borrower by the Holder (the “Default Notice”) (provided, however, that no Default Notice need be provided by the Holder
and no notice and no cure period shall apply in the case of the Events of Default specified in Sections 3.1, 3.2, 3.4, 3.5, 3.6,
3.7, 3.9, 3.10, 3.11, 3.14 3.16, 3.17, 3.18, 3.19 or 3.20 above), this Note shall become immediately due and payable and the Borrower
shall pay to the Holder, in full satisfaction of its obligations hereunder, an amount (the “Default Amount”) equal
to 125% of the Principal Amount then outstanding plus accrued interest (including any Default Interest) through the date of full
repayment. Holder may, in its sole discretion, determine to accept payment part in Common Stock and part in cash. For purposes
of payments in Common Stock, the conversion formula set forth in Section 1.2 shall apply. Upon an uncured Event of Default, all
amounts payable hereunder shall immediately become due and payable, all without demand, presentment or notice, all of which hereby
are expressly waived by the Borrower, together with all costs, including, without limitation, legal fees and expenses, of collection,
and the Holder shall be entitled to exercise all other rights and remedies available at law or in equity, including, without limitation,
those set forth in Section 3.22 below.

 

    	33

    	 

     

3.22 Holder’s Right
to Confession of Judgment. Upon the occurrence and during the continuation of any Event of Default, and in addition to any
other right or remedy of the Holder hereunder, under the Purchase Agreement or otherwise at law or in equity, the Borrower hereby
irrevocably authorizes and empowers Holder or its legal counsel, each as the Borrower’s attorney-in-fact, to appear ex parte
and without notice to the Borrower to confess judgment against the Borrower for the unpaid amount of this Note as evidenced by
the Affidavit of Confession of Judgment signed by the Borrower as of the Issue Date and to be completed by the Holder or its counsel
pursuant to the foregoing power of attorney (which power is coupled with an interest), a copy of which is attached as Exhibit
B hereto (the “Affidavit”). The Affidavit shall set forth the amount then due hereunder, plus reasonable attorney’s
fees and cost of suit, and to release all errors, and waive all rights of appeal. The Borrower waives the right to contest Holder’s
rights under this Section 3.22, including without limitation the right to any stay of execution and the benefit of all exemption
laws now or hereafter in effect. No single exercise of the foregoing right and power to confess judgment will be deemed to exhaust
such power, whether or not any such exercise shall be held by any court to be invalid, voidable, or void, and such power shall
continue undiminished and may be exercised from time to time as the Holder may elect until all amounts owing on this Note have
been paid in full.

 

ARTICLE IV. MISCELLANEOUS

 

4.1 Failure or Indulgence
Not Waiver. No failure or delay on the part of the Holder 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 Holder existing hereunder are cumulative
to, and not exclusive of, any rights or remedies otherwise available.

any objection to jurisdiction and venue of any action instituted hereunder and shall not assert any defense based on lack of jurisdiction
or venue or based upon forum non conveniens. THE BORROWER HEREBY IRREVOCABLY WAIVES ANY RIGHT IT MAY HAVE, AND AGREES
NOT TO REQUEST, A JURY TRIAL FOR THE ADJUDICATION OF ANY DISPUTE HEREUNDER OR IN CONNECTION WITH OR ARISING OUT OF THIS NOTE OR
ANY TRANSACTIONS CONTEMPLATED HEREBY. Each party hereby irrevocably waives personal service of process and consents to process
being served in any suit, action or proceeding in connection with this Note or any other agreement, certificate, instrument or
document contemplated hereby or thereby 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 Note 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. The prevailing party in any action or dispute brought in connection
with this the Note or any other agreement, certificate, instrument or document contemplated hereby or thereby shall be entitled
to recover from the other party its reasonable attorney’s fees and costs.

 

4.7 Certain Amounts.
Whenever pursuant to this Note the Borrower is required to pay an amount in excess of the outstanding Principal Amount (or the
portion thereof required to be paid at that time) plus accrued and unpaid interest plus Default Interest on such interest, the
Borrower and the Holder agree that the actual damages to the Holder from the receipt of cash payment on this Note may be difficult
to determine and the amount to be so paid by the Borrower represents stipulated damages and not a penalty and is intended to compensate
the Holder in part for loss of the opportunity to convert this Note and to earn a return from the sale of shares of Common Stock
acquired upon conversion of this Note at a price in excess of the price paid for such shares pursuant to this Note. The Borrower
and the Holder hereby agree that such amount of stipulated damages is not plainly disproportionate to the possible loss to the
Holder from the receipt of a cash payment without the opportunity to convert this Note into shares of Common Stock.

 

4.8 Purchase Agreement.
The Company and the Holder shall be bound by the applicable terms of the Purchase Agreement and the documents entered into in connection
herewith and therewith.

 

4.9 Notice of Corporate
Events. Except as otherwise provided below, the Holder of this Note shall have no rights as a Holder of Common Stock unless
and only to the extent that it converts this Note into Common Stock. The Borrower shall provide the Holder with prior notification
of any meeting of the Borrower’s shareholders (and copies of proxy materials and other information sent to shareholders).
In the event of any taking by the Borrower of a record of its shareholders for the purpose of determining shareholders who are
entitled to receive payment of any dividend or other distribution, any right to subscribe for, purchase or otherwise acquire (including
by way of merger, consolidation, reclassification or recapitalization) any share of any class or any other securities or property,
or to receive any other right, or for the purpose of determining shareholders who are entitled to vote in connection with any Change
in Control or any proposed liquidation, dissolution or winding up of the Borrower, the Borrower shall mail a notice to the Holder,
at least twenty (20) days prior to the record date specified therein (or thirty (30) days prior to the consummation of the transaction
or event, whichever is earlier), of the date on which any such record is to be taken for the purpose of such dividend, distribution,
right or other event, and a brief statement regarding the amount and character of such dividend, distribution, right or other event
to the extent known at such time. The Borrower shall make a public announcement of any event requiring notification to the Holder
hereunder substantially simultaneously with the notification to the Holder in accordance with the terms of this Section 4.9.

 

    	35

    	 

     

4.10 Remedies. The
Borrower acknowledges that a breach by it of its obligations hereunder will cause irreparable harm to the Holder, by vitiating
the intent and purpose of the transaction contemplated hereby. Accordingly, the Borrower acknowledges that the remedy at law for
a breach of its obligations under this Note will be inadequate and agrees, in the event of a breach by the Borrower of the provisions
of this Note, that the Holder 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 Note and
to enforce specifically the terms and provisions thereof, without the necessity of showing economic loss and without any bond or
other security being required.

 

4.11 Construction; Headings.
This Note shall be deemed to be jointly drafted by the Company and the Holder and shall not be construed against any person as
the drafter hereof. The headings of this Note are for convenience of reference and shall not form part of, or affect the interpretation
of, this Note.

 

4.12 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 action or proceeding that may be brought by the Holder in order to enforce any right
or remedy under this Note. Notwithstanding any provision to the contrary contained in this Note, it is expressly agreed and provided
that the total liability of the Company under this Note for payments which under New York law are in the nature of interest shall
not exceed the maximum lawful rate authorized under applicable law (the “Maximum Rate”), 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 which
under New York law in the nature of interest that the Company may be obligated to pay under this Note exceed such Maximum Rate.
It is agreed that if the maximum contract rate of interest allowed by New York law and applicable to this Note is increased or
decreased by statute or any official governmental action subsequent to the Issue Date, the new maximum contract rate of interest
allowed by law will be the Maximum Rate applicable to this Note 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 the Holder with respect to indebtedness evidenced by this the Note, such excess shall be applied by the Holder to the unpaid
principal balance of any such indebtedness or be refunded to the Company, the manner of handling such excess to be at the Holder’s
election.

 

4.13 Severability.
In the event that any provision of this Note is invalid or unenforceable under any applicable statute or rule of law (including
any judicial ruling), then such provision shall be deemed inoperative to the extent that it may conflict therewith and shall be
deemed modified to conform with such statute or rule of law. Any such provision which may prove invalid or unenforceable under
any law shall not affect the validity or enforceability of any other provision of this Note.

Issuance Date: June [__], 2016

 

QUANTUMSPHERE, INC.

Common Stock
Purchase Warrant

 

THIS CERTIFIES THAT,
for value received, __________________________ (the “Holder”), is entitled to subscribe for and purchase,
at the Exercise Price (as defined below), from QUANTUMSPHERE, INC., a Nevada corporation (the “Company”),
shares of the Company’s common stock, par value $0.001 (the “Common Stock”), at any time prior to the
5:00 p.m., Eastern time, on June [__], 2021 (the “Warrant Exercise Term”).

 

This Warrant is issued
in connection and subject to, the terms and conditions described in the Securities Purchase Agreement, dated June [__], 2016, between
the Holder and the Company (the “Agreement”). Capitalized terms used herein and not otherwise defined shall
have the definitions ascribed to such terms in the Agreement. As used herein, the term “Trading Day” means any
day that shares of Common Stock are listed for trading or quotation on the OTCBB (as defined in the Agreement), any tier of the
NASDAQ Stock Market, the New York Stock Exchange or the NYSE MKT (the “Trading Market”).

 

This Warrant is subject
to the following terms and conditions:

 

1. Shares. The Holder
has, subject to the terms set forth herein, the right to purchase up to an aggregate of _______________________ (________________)
shares (the “Shares”) of Common Stock at a per share exercise price equal to the price per share of the Company’s
next equity round of financing (the “Private Placement”)(as subject to adjustment as provided for herein, the “Exercise
Price”).

 

2. Exercise of Warrant.

 

(a) Exercise. This
Warrant may be exercised by the Holder at any time following the initial closing of the Private Placement, and prior to the expiration
of the Warrant Exercise Term, in whole or in part, by delivering the notice of exercise attached as Exhibit A hereto (the
“Notice of Exercise”), duly executed by the Holder to the Company at its principal office, or at such other
office as the Company may designate, accompanied by payment, in cash by wire transfer of immediately available funds to the order
of the Company and to an account designated by the Company, of the amount obtained by multiplying the number of Shares designated
in the Notice of Exercise by the Exercise Price (the “Purchase Price”). For purposes hereof, “Exercise
Date” shall mean the date on which all deliveries required to be made to the Company upon exercise of this Warrant pursuant
to this Section 2(a) shall have been made.

 

    	 

    	 

     

(b) Issuance of Shares.
Upon receipt by the Company from the Holder of a facsimile transmission or e-mail or overnight FedEx of a Notice of Exercise, the
Company shall issue and deliver or cause to be issued and delivered to or upon the order of the Holder certificates for the Shares
(or cause the electronic delivery of the Shares as contemplated by Section 2(d) hereof) within three (3) Trading Days after such
receipt (the “Deadline”). If the Company shall fail for any reason or for no reason to issue to the Holder on
or prior to the Deadline a certificate for the number of Shares or to which the Holder is entitled hereunder and register such
Shares on the Company’s share register or to credit the Holder’s balance account with DTC (as defined below) for such
number of Shares to which the Holder is entitled upon the Holder’s exercise of this Warrant (an “Exercise Failure”),
then, in addition to all other remedies available to the Holder, (i) the Company shall pay in cash to the Holder on each day after
the Deadline and during such Exercise Failure an amount equal to 2.0% of the product of (A) the sum of the number of Exercise Shares
not issued to the Holder on or prior to the Deadline and to which the Holder is entitled and (B) the closing sale price of the
Common Stock on the Trading Day immediately preceding the last possible date which the Company could have issued such Shares to
the Holder without violating this Section 2(b) and (ii) the Holder, upon written notice to the Company, may void its Notice of
Exercise with respect to, and retain or have returned, as the case may be, any portion of this Warrant that has not been exercised
pursuant to such Notice of Exercise; provided that the voiding of an Notice of Exercise shall not affect the Company’s obligations
to make any payments which have accrued prior to the date of such notice. In addition to the foregoing, if on or prior to the Deadline
the Company shall fail to issue and deliver a certificate to the Holder and register such Shares on the Company’s share register
or credit the Holder’s balance account with DTC for the number of Shares to which the Holder is entitled upon the Holder’s
exercise hereunder or pursuant to the Company’s obligation pursuant to clause (ii) below, and if on or after such Trading
Day the Holder purchases (in an open market transaction or otherwise) shares of Common Stock to deliver in satisfaction of a sale
by the Holder of shares of Common Stock issuable upon such exercise that the Holder anticipated receiving from the Company, then
the Company shall, within three (3) Trading Days after the Holder’s request and in the Holder’s discretion, either
(i) pay cash to the Holder in an amount equal to the Holder’s total purchase price (including brokerage commissions and other
reasonable and customary out-of-pocket expenses, if any) for the shares of Common Stock so purchased (the “Buy-In Price”),
at which point the Company’s obligation to deliver such certificate (and to issue such Shares) or credit such Holder’s
balance account with DTC for such Shares shall terminate, or (ii) promptly honor its obligation to deliver to the Holder a certificate
or certificates representing such Shares or credit such Holder’s balance account with DTC and pay cash to the Holder in an
amount equal to the excess (if any) of the Buy-In Price over the product of (A) such number of shares of Common Stock, times (B)
the closing sales price of the Common Stock on the date of exercise. 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 the Shares (or
to electronically deliver such Shares) upon the exercise of this Warrant as required pursuant to the terms hereof.

 

(c) Obligation of Company
to Deliver Common Stock. Upon receipt by the Company of a Notice of Exercise, the Holder shall be deemed to be the holder of
record of the Shares issuable upon such exercise and all rights with respect to the portion of this Warrant being so exercised
shall forthwith terminate except the right to receive the Common Stock or other securities, cash or other assets, as herein provided,
on such exercise. If the Holder shall have given a Notice of Exercise as provided herein, the Company’s obligation to issue
and deliver the Shares (or cause the electronic delivery of the Shares as contemplated by Section 2(d) hereof) shall be absolute
and unconditional, irrespective of the absence of any action by the Holder to enforce the same, any waiver or consent with respect
to any provision thereof, the recovery of any judgment against any person or any action to enforce the same, any failure or delay
in the enforcement of any other obligation of the Company to the holder of record, or any setoff, counterclaim, recoupment, limitation
or termination, or any breach or alleged breach by the Holder of any obligation to the Company, and irrespective of any other circumstance
which might otherwise limit such obligation of the Company to the Holder in connection with such exercise.

 

(d) Delivery of Shares
by Electronic Transfer. In lieu of delivering physical certificates representing the Shares issuable upon exercise hereof,
provided the Company is participating in the Depository Trust Company (“DTC”) Fast Automated Securities Transfer
program, upon request of the Holder, the Company shall use its best efforts to cause its transfer agent to electronically transmit
the Share issuable upon exercise hereof to the Holder by crediting the account of Holder’s Prime Broker with DTC through
its Deposit Withdrawal Agent Commission system.

 

(e) Taxes. The issuance
of the Shares upon the exercise of this Warrant, and the delivery of certificates or other instruments representing such Shares,
shall be made without charge to the Holder for any tax or other charge of whatever nature in respect of such issuance and the Company
shall bear any such taxes in respect of such issuance.

 

    	 

    	 

     

(f) Limitation on Beneficial
Ownership. Notwithstanding anything to the contrary contained herein, that in no event shall the Holder be entitled to exercise
any portion of this Warrant in excess of that portion of this Warrant upon conversion of which the sum of (1) the number of shares
of Common Stock beneficially owned by the Holder and its affiliates (other than shares of Common Stock which may be deemed beneficially
owned through the ownership of the unexercised portion of this Warrant or the unexercised or unconverted portion of any other security
of the Company subject to a limitation on conversion or exercise analogous to the limitations contained herein) and (2) the number
of Shares issuable upon the exercise of the portion of this Warrant with respect to which the determination of this proviso is
being made, would result in beneficial ownership by the Holder and its affiliates of more than 4.99% of the then outstanding shares
of Common Stock. The “beneficial ownership” of the Holder shall be determined in accordance with Section 13(d) of the
1934 Act, and Regulations 13D-G thereunder, except as otherwise provided in clause (1) of above, provided, however,
that the limitations on exercise may be waived by the Holder upon, at the election of the Holder, not less than 61 days’
prior notice to the Company, and the provisions of the conversion limitation shall continue to apply until such 61st day (or such
later date, as determined by the Holder, as may be specified in such notice of waiver).

 

(g) Cashless Exercise.
Notwithstanding anything contained herein to the contrary, if and only if a registration statement pursuant to the 1933 Act covering
the resale of all or any portion of the Warrant Shares is not available for the resale of such Warrant Shares (such unregistered
portion of the Warrant Shares, the “Unavailable Warrant Shares”), the Holder may, in its sole discretion, exercise
this Warrant solely with respect to the Unavailable Warrant Shares and, in lieu of making the cash payment otherwise contemplated
to be made to the Company upon such exercise in payment of the aggregate Exercise Price for such Unavailable Warrant Shares, elect
instead to receive upon such exercise the “Net Number” of shares of Common Stock determined according to the following
formula (a “Cashless Exercise”):

 

	 	X 	=	Y (A - B)
	 	 	 	     A

 

       with:

 

X = the number of Warrant
Shares to be issued to the Holder

 

Y = the number of Unavailable
Warrant Shares with respect to which the Warrant is being exercised

 

A = the fair value per share
of Common Stock on the date of exercise of this Warrant

 

B = the then-current Exercise
Price of the Warrant

 

Solely for the purposes of
this paragraph, “fair value” per share of Common Stock shall mean (A) the average of the closing sales prices on the
Trading Market for the twenty (20) Trading Days immediately preceding the date on which the Notice of Exercise is deemed to have
been sent to the Company, or (B) if the Common Stock is not publicly traded as set forth above, as reasonably and in good faith
determined by the Board of Directors of the Company as of the date which the Notice of Exercise is deemed to have been sent to
the Company.

 

For purposes of Rule 144
promulgated under the 1933 Act, it is intended, understood and acknowledged that the Warrant Shares issued in a Cashless Exercise
transaction shall be deemed to have been acquired by the Holder, and the holding period for such shares shall be deemed to have
commenced, on the date this Warrant was originally issued.

 

    	 

    	 

     

3. Adjustment of Exercise
Price and Other Events.

 

(a) Adjustment for Reclassification,
Consolidation or Merger. If while this Warrant, or any portion hereof, remains outstanding and unexpired there shall be (i)
a reorganization or recapitalization (other than a combination, reclassification, exchange or subdivision of shares otherwise provided
for herein), (ii) a merger or consolidation of the Company with or into another corporation or other entity in which the Company
shall not be the surviving entity, or a reverse merger in which the Company shall be the surviving entity but the shares of the
Company’s capital stock outstanding immediately prior to the merger are converted by virtue of the merger into other property,
whether in the form of securities, cash or otherwise, or (iii) a sale or transfer of the Company’s properties and assets
as, or substantially as, an entirety to any other corporation or other entity in one transaction or a series of related transactions,
then, as a part of such reorganization, recapitalization, merger, consolidation, sale or transfer, unless otherwise directed by
the Holder, all necessary or appropriate lawful provisions shall be made so that the Holder shall thereafter be entitled to receive
upon exercise of this Warrant, during the period specified herein and upon payment of the Exercise Price then in effect, the number
of shares of capital stock or other securities or property that a holder of the Shares deliverable upon exercise of this Warrant
would have been entitled to receive in such reorganization, recapitalization, merger, consolidation, sale or transfer if this Warrant
had been exercised immediately prior to such reorganization, recapitalization, merger, consolidation, sale or transfer, all subject
to further adjustment as provided in this Section 3. If the per share consideration payable to the Holder for Shares in connection
with any such transaction is in a form other than cash or marketable securities, then the value of such consideration shall be
determined in good faith by the Company’s Board of Directors. The foregoing provisions of this paragraph shall similarly
apply to successive reorganizations, recapitalizations, mergers, consolidations, sales and transfers and to the capital stock or
securities of any other corporation that are at the time receivable upon the exercise of this Warrant. In all events, appropriate
adjustment shall be made in the application of the provisions of this Warrant with respect to the rights and interests of the Holder
after the transaction, to the end that the provisions of this Warrant shall be applicable after that event, as near as reasonably
may be, in relation to any shares or other property deliverable or issuable after such reorganization, recapitalization, merger,
consolidation, sale or transfer upon exercise of this Warrant.

 

(b) Adjustments for Split,
Subdivision or Combination of Shares. If while this Warrant, or any portion hereof, remains outstanding and unexpired the Company
shall subdivide (by any stock split, stock dividend, recapitalization, reorganization, reclassification or otherwise) the shares
of Common Stock subject to acquisition hereunder, then, after the date of record for effecting such subdivision, the Exercise Price
in effect immediately prior to such subdivision will be proportionately reduced and the number of shares of Common Stock subject
to acquisition upon exercise of the Warrant will be proportionately increased. If the Company at any time combines (by reverse
stock split, recapitalization, reorganization, reclassification or otherwise) the shares of Common Stock subject to acquisition
hereunder, then, after the record date for effecting such combination, the Exercise Price in effect immediately prior to such combination
will be proportionately increased and the number of shares of Common Stock subject to acquisition upon exercise of the Warrant
will be proportionately decreased.

 

(c) Adjustments for Dividends
in Stock or Other Securities or Property. If while this Warrant, or any portion hereof, remains outstanding and unexpired,
the holders of any class of securities as to which purchase rights under this Warrant exist at the time shall have received or,
on or after the record date fixed for the determination of eligible stockholders, shall have become entitled to receive, without
payment therefor, other or additional stock or other securities or property (other than cash) of the Company by way of dividend,
then and in each case, this Warrant shall represent the right to acquire, in addition to the number of shares of such class of
security receivable upon exercise of this Warrant, and without payment of any additional consideration therefor, the amount of
such other or additional stock or other securities or property (other than cash) of the Company that such holder would hold on
the date of such exercise had it been the holder of record of the class of security receivable upon exercise of this Warrant on
the date hereof and had thereafter, during the period from the date hereof to and including the date of such exercise, retained
such shares and/or all other additional stock available to it as aforesaid during said period, giving effect to all adjustments
called for during such period by the provisions of this Section 3.

 

(d) Adjustments for Dilutive
Issuances . If, at any time while this Warrant is outstanding, the Company sells or grants any option to purchase or sells
or grants any right to reprice, or otherwise disposes of or issues (or announces any sale, grant or any option to purchase or other
disposition), any Common Stock or other securities entitling any person to acquire shares of Common Stock at an effective price
per share that is lower than the then Exercise Price (such lower price, the “Base Exercise Price” and such issuances,
collectively, a “Dilutive Issuance”) (if the holder of the Common Stock or other securities so issued shall at any
time, whether by operation of purchase price adjustments, reset provisions, floating conversion, exercise or exchange prices or
otherwise, or due to warrants, options or rights per share which are issued in connection with such issuance, be entitled to receive
shares of Common Stock at an effective price per share that is lower than the Exercise Price, such issuance shall be deemed to
have occurred for less than the Exercise Price on such date of the Dilutive Issuance), then the Exercise Price shall be reduced
to equal the Base Exercise Price. Such adjustment shall be made whenever such Common Stock or other securities are issued. Notwithstanding
the foregoing, no adjustment will be made under this Section 3(d) in respect of an Exempt Issuance. In the event of an issuance
of securities involving multiple tranches or closings, any adjustment pursuant to this Section 3(d) shall be calculated as if all
such securities were issued at the initial closing.

 

    	 

    	 

     

An “Exempt Issuance”
shall mean the issuance of (i) shares of Common Stock or other securities to employees, officers or directors of the Company pursuant
to any stock or option or similar equity incentive plan duly adopted for such purpose, by a majority of the non-employee members
of the Board of Directors or a majority of the members of a committee of non-employee directors established for such purpose in
a manner which is consistent with the Company’s prior business practices; (ii) securities issued pursuant to a merger, consolidation,
acquisition or similar business combination approved by a majority of the disinterested directors of the Company, provided that
any such issuance shall only be to a person (or to the equityholders of a person) which is, itself or through its subsidiaries,
an operating company or an owner of an asset in a business synergistic with the business of the Company and shall provide to the
Company additional benefits in addition to the investment of funds, but shall not include a transaction in which the Company is
issuing securities primarily for the purpose of raising capital or to an entity whose primary business is investing in securities;
or (iii) securities issued pursuant to any equipment loan or leasing arrangement, real property leasing arrangement or debt financing
from a bank or similar financial institution approved by a majority of the disinterested directors of the Company.

 

(e) Fundamental Transactions.
The Company shall not enter into or be party to a Fundamental Transaction unless the entity succeeding to the Company (the “Successor
Entity”) assumes in writing all of the obligations of the Company under this Warrant and the Agreement. Upon occurrence
or consummation of the Fundamental Transaction, the Company and the Successor Entity shall deliver to the Holder confirmation that
there shall be issued upon exercise of this Warrant at any time after the occurrence or consummation of the Fundamental Transaction,
as elected by the Holder solely at its option, shares of Common Stock, shares of capital stock of the Successor Entity (“Successor
Capital Stock”) or, in lieu of the shares of Common Stock or Successor Capital Stock (or other securities, cash, assets
or other property purchasable upon the exercise of this Warrant prior to such Fundamental Transaction), such shares of stock, securities,
cash, assets or any other property whatsoever (including warrants or other purchase or subscription rights), which for purposes
of clarification may continue to be shares of Common Stock, if any, that the Holder would have been entitled to receive upon the
happening of such Fundamental Transaction or the record, eligibility or other determination date for the event resulting in such
Fundamental Transaction, had this Warrant been exercised immediately prior to such Fundamental Transaction or the record, eligibility
or other determination date for the event resulting in such Fundamental Transaction, as adjusted in accordance with the provisions
of this Warrant. In addition to and not in substitution for any other rights hereunder, prior to the occurrence or consummation
of any Fundamental Transaction pursuant to which holders of shares of Common Stock are entitled to receive securities, cash, assets
or other property with respect to or in exchange for shares of Common Stock (a “Corporate Event”), the Company
shall make appropriate provision to insure that, and any applicable Successor Entity shall ensure that, and it shall be a required
condition to the occurrence or consummation of such Corporate Event that, the Holder will thereafter have the right to receive
upon exercise of this Warrant at any time after the occurrence or consummation of the Corporate Event, shares of Common Stock or
Successor Capital Stock or, if so elected by the Holder, in lieu of the shares of Common Stock (or other securities, cash, assets
or other property) purchasable upon the exercise of this Warrant prior to such Corporate Event. The provisions of this Section
2(e) shall apply similarly and equally to successive Fundamental Transactions and Corporate Events.

is the surviving corporation) another entity, or (ii) sell, assign, transfer, convey or otherwise dispose of all or substantially
all of the properties or assets of the Company to one or more entities, or (iii) make, or allow one or more entities to make, or
allow the Company to be subject to or have its Common Stock be subject to or party to one or more entities making, a purchase,
tender or exchange offer that is accepted by the holders of at least either (x) 50% of the outstanding shares of Common Stock,
(y) 50% of the outstanding shares of Common Stock calculated as if any shares of Common Stock held by all entities making or party
to, or affiliated with any entities making or party to, such purchase, tender or exchange offer were not outstanding; or (z) such
number of shares of Common Stock such that all entities making or party to, or Affiliated with any entity making or party to, such
purchase, tender or exchange offer, become collectively the beneficial owners (as defined in Rule 13d-3 under the 1934 Act) of
at least 50% of the outstanding shares of Common Stock, or (iv) consummate a stock purchase agreement or other business combination
(including, without limitation, a reorganization, recapitalization, spin-off or scheme of arrangement) with one or more entities
whereby all such entities, individually or in the aggregate, acquire, either (x) at least 50% of the outstanding shares of Common
Stock, (y) at least 50% of the outstanding shares of Common Stock calculated as if any shares of Common Stock held by all the entities
making or party to, or affiliated with any entity making or party to, such stock purchase agreement or other business combination
were not outstanding; or (z) such number of shares of Common Stock such that the entities become collectively the beneficial owners
(as defined in Rule 13d-3 under the 1934 Act) of at least 50% of the outstanding shares of Common Stock, or (v) reorganize, recapitalize
or reclassify its Common Stock such that such modified Common Stock no longer has the residual right to dividends or distributions
form the Company or the residual right to vote on matters given to the common stock holders under Nevada law, (B) that the Company
shall, directly or indirectly, including through subsidiaries, affiliates or otherwise, in one or more related transactions, allow
any entity individually or entities in the aggregate to be or become the “beneficial owner” (as defined in Rule 13d-3
under the 1934 Act), directly or indirectly, whether through acquisition, purchase, assignment, conveyance, tender, tender offer,
exchange, reduction in outstanding shares of Common Stock, merger, consolidation, business combination, reorganization, recapitalization,
spin-off, scheme of arrangement, reorganization, recapitalization or reclassification or otherwise in any manner whatsoever, of
either (x) at least 50% of the aggregate ordinary voting power represented by issued and outstanding Common Stock, (y) at least
50% of the aggregate ordinary voting power represented by issued and outstanding Common Stock not held by all such entities as
of the date of this Warrant calculated as if any shares of Common Stock held by all such entities were not outstanding, or (z)
a percentage of the aggregate ordinary voting power represented by issued and outstanding shares of Common Stock or other equity
securities of the Company sufficient to allow such entities to effect a statutory short form merger or other transaction requiring
other stockholders of the Company to surrender their shares of Common Stock without approval of the stockholders of the Company
or (C) directly or indirectly, including through subsidiaries, affiliates or otherwise, in one or more related transactions, the
issuance of or the entering into any other instrument or transaction structured in a manner to circumvent, or that circumvents,

conformity with the terms of this definition to the extent necessary to correct this definition or any portion of this definition
which may be defective or inconsistent with the intended treatment of such instrument or transaction.

 

(i) Notice of Fundamental
Transactions and Adjustments. The Company shall provide the Holder with no less than five (5) business days written notice
of the public announcement of any Fundamental Transaction. In addition, upon any adjustment of the Exercise Price and any increase

Except as expressly provided in Section 3 hereof, the Holder, as such, shall not be entitled to vote or receive dividends or be
deemed the holder of the Shares or any other securities of the Company that may at any time be issuable on the exercise hereof
for any purpose, nor shall anything contained herein be construed to confer upon the Holder, as such, any of the rights of a stockholder
of the Company or any right to vote for the election of directors or upon any matter submitted to stockholders at any meeting thereof,
or to give or withhold consent to any corporate action (whether upon any recapitalization, issuance of stock, reclassification
of stock, change of par value, consolidation, merger, conveyance, or otherwise) or to receive notice of meetings, or otherwise
until this Warrant shall have been exercised and the Shares purchasable upon the exercise hereof shall have been issued, as provided
herein.

 

8. Transfer; Multiple
Warrants; Lost Warrant; New Warrants. This Warrant and the Shares may be offered for sale, sold, transferred, pledged or assigned
without the consent of the Company, provided that any such offer, sale, transfer, pledge or assignment must be undertaken in accordance

Holder at the principal office of the Company, for a new Warrant or Warrants representing in the aggregate the right to purchase
the number of Shares then underlying this Warrant, and each such new Warrant will represent the right to purchase such portion
of such Shares as is designated by the Holder at the time of such surrender. Upon receipt by the Company of evidence reasonably

of any indemnification undertaking by the Holder to the Company in customary form and, in the case of mutilation, upon surrender

WHEREAS:

 

A. Pledgees have agreed to

SECTION
3. Security for Obligations. The security interest created hereby in the Pledged Collateral constitutes continuing collateral
security for all of the following obligations, whether now existing or hereafter incurred (the “Obligations”):

or not the payment of such interest is unenforceable or is not allowable due to the existence of such case, proceeding or other
action), all fees, commissions, expense reimbursements, indemnifications and all other amounts due or to become due to Pledgees
under the Notes.

 

SECTION 4. Delivery of
the Pledged Collateral.

 

(a) FirstFire
Global Opportunities Fund LLC (the “Collateral Agent”) shall hold the Pledged Shares for the benefit of the Pledgees
and each Pledgor further agrees to execute such other documents and to take such other actions as the Collateral Agent deems reasonably
necessary or desirable to create and perfect the security interests intended to be created hereunder, including, without limitation,
duly executed undated stock powers endorsed in blank, with medallion guarantee(s), to effect the foregoing and to permit Pledgees

SECTION 5. Representations
and Warranties. Each Pledgor represents and warrants, severally and jointly, as follows:

 

(a) The execution,
delivery and performance by the Pledgors of this Agreement and the exercise by any Pledgee of any of its rights and remedies in
accordance with the terms of this Agreement and applicable securities law will not contravene any law or any contractual restriction
binding on or affecting the Pledgors or any of its properties and do not and will not result in or require the creation of any
lien upon or with respect to any of its properties other than pursuant to this Agreement.

 

(b) The Pledgors
are and will be at all times the beneficial owner of the Pledged Collateral free and clear of any lien or option except for the
security interest created by this Agreement.

 

(c) No authorization
or approval or other action by, and no notice to or filing with, any governmental authority or other regulatory body is required
for the grant by the Pledgors, or the perfection, of the security interest purported to be created hereby in the Pledged Collateral
or the exercise by any Pledgee of any of its rights and remedies hereunder, except as may be required in connection with any sale
of any Pledged Collateral by laws affecting the offering and sale of securities generally, including the foreclosure procedures
sanctioned under the interpretations of the securities laws.

 

(d) This Agreement
creates a valid security interest in favor of the Pledgees in the Pledged Collateral, as security for the Obligations. Such security
interest is, or in the case of Pledged Collateral in which the Pledgors obtain rights after the date hereof, will be, a perfected,
first priority security interest. All action necessary to perfect and protect such security interest has been duly taken, except
for Pledgees’ having possession of security certificates constituting Pledged Collateral after the date hereof and obtaining
control of uncertificated securities and security entitlements constituting Pledged Collateral after the date hereof.

 

SECTION 6. Covenants as
to the Pledged Collateral. So long as any of the Obligations shall remain outstanding, each Pledgor will, unless Collateral
Agent (who shall act at the direction of holders of a majority of the Notes then outstanding) shall otherwise consent in writing:

 

(a) keep adequate
records concerning the Pledged Collateral and permit Collateral Agent or any agents or representatives of Collateral Agent at any
reasonable time and from time to time to examine and make copies of and abstracts from such records;

 

(b) at its expense,
promptly deliver to Collateral Agent a copy of each notice or other communication received by it in respect of the Pledged Collateral;

 

(c) at its expense,
defend Pledgees’ right, title and security interest in and to the Pledged Collateral against the claims of any person or
entity;

 

(d) at its expense,
at any time and from time to time, promptly execute and deliver all further instruments and documents and take all further action
that may be necessary or desirable or that Collateral Agent may reasonably request in order to (i) perfect and protect the security
interest purported to be created hereby, or (ii) enable Collateral Agent to exercise and enforce the Pledgees’ rights and
remedies hereunder in respect of the Pledged Collateral;

 

    	 

    	 

     

(e) not sell,
assign (by operation of law or otherwise), transfer, exchange or otherwise dispose of any Pledged Collateral or any interest therein;

 

(f) not create
or suffer to exist any lien upon or with respect to any Pledged Collateral except for the security interest created hereby;

or consent to any amendment or other modification or waiver with respect to any Pledged Collateral or enter into any agreement
or permit to exist any restriction with respect to any Pledged Collateral other than pursuant hereto; and

 

(h) not take
or fail to take any action which would in any manner impair the value or enforceability of Pledgees’ security interest in
any Pledged Collateral.

 

SECTION 7. Voting Rights,
Etc. in Respect of the Pledged Collateral.

 

(a) So long as
no Event of Default or event which, with the giving of notice or lapse of time or both, would constitute an Event of Default, shall
have occurred and be continuing:

 

(i) each Pledgor
may exercise any and all voting and other consensual rights pertaining to any Pledged Collateral for any purpose not inconsistent
with the terms of the Note; and

 

(ii) each Pledgee
will execute and deliver (or cause to be executed and delivered) to each Pledgor all such proxies and other instruments as such
Pledgor may reasonably request for the purpose of enabling such Pledgor to exercise the voting and other rights which it is entitled
to exercise pursuant to paragraph Section 7(a)(i) hereof.

 

(b) Upon the
occurrence and during the continuance of an Event of Default or an event which, with the giving of notice or the lapse of time
or both, would constitute an Event of Default:

 

(i) all rights
of any Pledgor to exercise the voting and other consensual rights which it would otherwise be entitled to exercise pursuant to
Section 7(a)(i) hereof shall cease, and all such rights shall thereupon become vested in the Pledgees which shall thereupon have
the sole right to exercise such voting and other consensual rights; and

 

(ii) without limiting
the generality of the foregoing, each Pledgee may at its option exercise any and all rights of conversion, exchange, subscription
or any other rights, privileges or options pertaining to any Pledged Collateral as if it were the absolute owner thereof, including,
without limitation, the right to exchange, in its discretion, any and all of such Pledged Collateral upon the merger, consolidation,
reorganization, recapitalization or other adjustment of the Company, or upon the exercise of any right, privilege or option pertaining
to any Pledged Collateral, and, in connection therewith, to deposit and deliver any and all of the Pledged Collateral with any
committee, depository, transfer agent, registrar or other designated agent upon such terms and conditions as it may determine.

hereby authorizes Collateral Agent to file, without the signature of such Pledgor where permitted by law, one or more financing
or continuation statements, and amendments thereto, relating to the Pledged Collateral.

 

(b) Each Pledgor
hereby irrevocably appoints Collateral Agent (who shall act at the direction of holders of 50% of the Notes then outstanding) as
such Pledgor’s attorney-in-fact and proxy, with full authority, exercisable only during the existence of an Event of Default,
in the place and stead of such Pledgor and in the name of such Pledgor or otherwise, from time to time in Collateral Agent’s
discretion, to take any action and to execute any instrument which Collateral Agent may deem necessary or advisable to accomplish
the purposes of this Agreement (subject to the rights of such Pledgor under Section 7(a) hereof), including, without limitation,
to receive, endorse and collect all instruments made payable to such Pledgor representing any dividend or other distribution in
respect of any of the Pledged Collateral and to give full discharge for the same. This power is coupled with an interest and is
irrevocable until all of the Obligations are satisfied in full.

 

(c) If any Pledgor
fails to perform any agreement or obligation contained herein, Collateral Agent itself may perform, or cause performance of, such
agreement or obligation with respect to Pledged Collateral, and the expenses of Collateral Agent incurred in connection therewith
shall be payable by such Pledgor pursuant to Section 10 hereof and shall be secured by the Pledged Collateral.

 

SECTION 10. Indemnity

fees and disbursements) to the extent that they arise out of or otherwise result from this Agreement (including, without limitation,
enforcement of this Agreement), except, as to any such indemnified person or entity, claims, losses or liabilities resulting solely
and directly from such person or entity’s gross negligence or willful misconduct as determined by a final judgment of a court
of competent jurisdiction and except to the extent that such claims, losses or liabilities result from failure of such indemnified
person or entities to comply with the securities laws.

 

    	 

    	 

     

SECTION 11. Notices.
Whenever notice is required to be given under this Agreement, unless otherwise provided herein, such notice shall be given in accordance
with the terms of the Note.

 

SECTION 12. Security Interest
Absolute. To the extent permitted by law, all rights of each Pledgee and each Pledgor hereunder shall be absolute and unconditional
irrespective of: (i) any lack of validity or enforceability of any ancillary agreement or any other agreement or instrument relating
thereto, (ii) any change in the time, manner or place of payment of, or in any other term in respect of, all or any of the Obligations,
or any other amendment or waiver of or consent to any departure from any guaranty, for all or any of the Obligations, or (iii)
any other circumstance which might otherwise constitute a defense available to, or a discharge of, each Pledgor in respect of the
Obligations. All authorizations and agencies contained herein with respect to any of the Pledged Collateral are irrevocable and
powers coupled with an interest.

 

SECTION 13. Miscellaneous.

 

(a) No amendment
of any provision of this Agreement shall be effective unless it is in writing and signed by each Pledgor and Collateral Agent,
and no waiver of any provision of this Agreement, and no consent to any departure by any Pledgor therefrom, shall be effective
unless it is in writing and signed by Collateral Agent, and then such waiver or consent shall be effective only in the specific
instance and for the specific purpose for which given.

 

(b) No failure
on the part of Collateral Agent to exercise, and no delay in exercising, any right hereunder or under any ancillary agreement shall
operate as a waiver thereof; nor shall any single or partial exercise of any such right preclude any other or further exercise
thereof or the exercise of any other right. The rights and remedies of the Pledgees provided herein and in the ancillary agreements
are cumulative and are in addition to, and not exclusive of, any rights or remedies provided by law. The rights of the Pledgees
under any ancillary agreement against any party thereto are not conditional or contingent on any attempt by any Pledgee to exercise
any of its rights under any other document against such party or against any other person or entity.

 

(c) Any provision
of this Agreement which is prohibited or unenforceable in any jurisdiction shall, as to such jurisdiction, be ineffective to the
extent of such prohibition or unenforceability without invalidating the remaining portions hereof or thereof or affecting the validity
or enforceability of such provision in any other jurisdiction.

 

(d) This Agreement
shall create a continuing security interest in the Pledged Collateral and shall (i) remain in full force and effect until the satisfaction
in full or release of the Obligations and (ii) be binding on each Pledgor and its successors and assigns and shall inure, together
with all rights and remedies of each Pledgee hereunder, to the benefit of each Pledgee and its successors, transferees and assigns;
provided that no such transfer or assignment shall be valid if it is in violation of applicable securities laws. Without limiting
the generality of clause (ii) of the immediately preceding sentence, subject to compliance with the applicable securities laws
and applicable provisions of the ancillary agreements, each Pledgee may assign or otherwise transfer all or any portion of the
Note, and its rights under the ancillary agreements, to any other person or entity, and such other person or entity shall thereupon
become vested with all of the benefits in respect thereof granted to such Pledgee herein or otherwise unless such benefit is unavailable
due to the status of such transferee or otherwise under applicable law. Upon any such permitted assignment or transfer, all references
in this Agreement to Pledgee shall mean the assignee of any Pledgee. None of the rights or obligations of any Pledgor hereunder
may be assigned or otherwise transferred without the prior written consent of Collateral Agent.

 

    	 

    	 

     

(e) Upon the
satisfaction in full of the Obligations, (i) this Agreement and the security interest created hereby shall terminate and all rights
to the Pledged Collateral, if any shall be remaining, shall revert to the Pledgors, respectively, and (ii) the Collateral Agent
will, upon any Pledgor’s request and at such Pledgor’s expense, (A) return to such Pledgor such of the Pledged Collateral
as shall not have been sold or otherwise disposed of, dealt with or applied pursuant to the terms hereof and of the ancillary agreements
and (B) execute and deliver to such Pledgor, without recourse, representation or warranty, such documents as such Pledgor shall
reasonably request to evidence such termination.

 

(f) All questions
concerning the construction, validity, enforcement and interpretation of this Agreement 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 hereby irrevocably submits to the exclusive jurisdiction of the state and federal courts sitting in the City of New
York, borough of Manhattan, for the adjudication of any dispute hereunder or in connection herewith or with any transaction contemplated
hereby or discussed herein, and hereby irrevocably waives, and agrees not to assert in any suit, action or proceeding, any claim
that it is not personally subject to the jurisdiction of any such court, that such suit, action or proceeding is improper. Each
party hereby irrevocably waives personal service of process and consents to process being served in any such suit, action or proceeding
by mailing a copy thereof to such party at the address 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 manner permitted by law. Each party hereto hereby irrevocably waives, to the fullest
extent permitted by applicable law, any and all right to trial by jury in any legal proceeding arising out of or relating to this
Agreement or the transactions contemplated hereby. If either party shall commence a Proceeding to enforce any provisions of this
Agreement, then the prevailing party in such Proceeding shall be reimbursed by the other party for its attorneys’ fees and

EXHIBIT
E

 

REGISTRATION
RIGHTS

 

All
of the Conversion Shares and Warrant Shares will be deemed “Registrable Securities” subject to the provisions of this
Exhibit E. All capitalized terms used but not defined in this Exhibit E shall have the meanings ascribed to such terms in the
Securities Purchase Agreement to which this Exhibit is attached.

 

1. Piggy-Back
Registration.

 

1.1 Piggy-Back
Rights. If at any time on or after the date of the Closing the Company proposes to file any Registration Statement under the
1933 Act (a “Registration Statement”) with respect to any offering of equity securities, or securities or other obligations
exercisable or exchangeable for, or convertible into, equity securities, by the Company for its own account or for shareholders
of the Company for their account (or by the Company and by shareholders of the Company), other than a Registration Statement (i)
filed in connection with any employee stock option or other benefit plan on Form S-8, (ii) for a dividend reinvestment plan or
(iii) in connection with a merger or acquisition, then the Company shall (x) give written notice of such proposed filing to the
holders of Registrable Securities appearing on the books and records of the Company as such a holder as soon as practicable but
in no event less than ten (10) days before the anticipated filing date of the Registration Statement, which notice shall describe
the amount and type of securities to be included in such Registration Statement, the intended method(s) of distribution, and the
name of the proposed managing underwriter or underwriters, if any, of the offering, and (y) offer to the holders of Registrable
Securities in such notice the opportunity to register the sale of such number of Registrable Securities as such holders may request
in writing within five (5) days following receipt of such notice (a “Piggy-Back Registration”). The Company shall
use its best efforts to cause such Registrable Securities to be included in such registration and its best efforts to cause the
managing underwriter or underwriters of a proposed underwritten offering to permit the Registrable Securities requested to be
included in a Piggy-Back Registration on the same terms and conditions as any similar securities of the Company and to permit
the sale or other disposition of such Registrable Securities in accordance with the intended method(s) of distribution thereof;
provided, however, in the case of an underwritten offering, the managing underwriter (or,
in the case of an offering that is not underwritten, an investment banker) shall advise the Company that, in its good faith opinion,
the number of securities requested and otherwise proposed to be included in such Piggy-Back Registration exceeds the number which
can be sold in such offering without adversely affecting the marketability of the offering, the Company will include in such Registration
Statement, to the extent of the number which the Company is so advised can be sold in such offering, first, the securities
the Company proposes to sell for its own account pursuant to such Registration Statement and second, the Registrable Securities
of the Holder requesting to be included in such Registration Statement and all other securities requested to be included in such
Registration on a pro rata basis, if any. All holders of Registrable Securities proposing to distribute their securities
through a Piggy-Back Registration that involves an underwriter or underwriters shall enter into an underwriting agreement in customary
form with the underwriter or underwriters selected for such Piggy-Back Registration.

 

1.2 Withdrawal.
Any holder of Registrable Securities may elect to withdraw such holder’s request for inclusion of Registrable Securities
in any Piggy-Back Registration by giving written notice to the Company of such request to withdraw prior to the effectiveness
of the Registration Statement. The Company (whether on its own determination or as the result of a withdrawal by persons making
a demand pursuant to written contractual obligations) may withdraw a Registration Statement at any time prior to the effectiveness
of such Registration Statement. Notwithstanding any such withdrawal, the Company shall pay all expenses incurred by the holders
of Registrable Securities in connection with such Piggy-Back Registration as provided in Section 1.5 below.

 

1.3 The
Company shall notify the holders of Registrable Securities at any time when a prospectus relating to such holder’s Registrable
Securities is required to be delivered under the 1933 Act, upon discovery that, or upon the happening of any event as a result
of which, the prospectus included in such Registration Statement, as then in effect, includes an untrue statement of a material
fact or omits to state any material fact required to be stated therein or necessary to make the statements therein not misleading
in light of the circumstances then existing. At the request of such holder, the Company shall also prepare, file and furnish to
such holder a reasonable number of copies of a supplement to or an amendment of such prospectus as may be necessary so that, as
thereafter delivered to the purchasers of the Registrable Securities, such prospectus shall not include an 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 not
misleading in light of the circumstances then existing. The holders of Registrable Securities shall not to offer or sell any Registrable
Securities covered by the Registration Statement after receipt of such notification until the receipt of such supplement or amendment.

1.4
 The Company may request a holder of Registrable Securities to furnish the Company such information with respect to such holder
and such holder’s proposed distribution of the Registrable Securities pursuant to the Registration Statement as the Company
may from time to time reasonably request in writing or as shall be required by law or by the SEC in connection therewith, and
such holders shall furnish the Company with such information.

 

1.5 All
fees and expenses incident to the performance of or compliance with this Exhibit E by the Company shall be borne by the Company
whether or not any Registrable Securities are sold pursuant to a Registration Statement. The fees and expenses referred to in
the foregoing sentence shall include, without limitation, (i) all registration and filing fees (including, without limitation,
fees and expenses of the Company’s counsel and independent registered public accountants) (A) with respect to filings made
with the SEC, (B) with respect to filings required to be made with any trading market on which the Common Stock is then listed
for trading, (C) in compliance with applicable state securities or Blue Sky laws reasonably agreed to by the Company in writing
(including, without limitation, fees and disbursements of counsel for the Company in connection with Blue Sky qualifications or
exemptions of the Registrable Securities) and (D) with respect to any filing that may be required to be made by any broker through
which a holder of Registrable Securities intends to make sales of Registrable Securities with the FINRA, (ii) printing expenses,
(iii) messenger, telephone and delivery expenses, (iv) fees and disbursements of counsel for the Company, (v) 1933 Act liability
insurance, if the Company so desires such insurance, (vi) fees and expenses of all other persons or entities retained by the Company
in connection with the consummation of the transactions contemplated by this Exhibit E and (vii) reasonable fees and disbursements
of a single special counsel for the holders of Registrable Securities (selected by holders of the majority of the Registrable
Securities requesting such registration), up to $10,000 for each registration. In addition, the Company shall be responsible for
all of its internal expenses incurred in connection with the consummation of the transactions contemplated by this Agreement (including,
without limitation, all salaries and expenses of its officers and employees performing legal or accounting duties), the expense
of any annual audit and the fees and expenses incurred in connection with the listing of the Registrable Securities on any securities
exchange as required hereunder. In no event shall the Company be responsible for any broker or similar commissions of any holder
of Registrable Securities.

 

1.6 The
Company and its successors and assigns shall indemnify and hold harmless the Buyer, each holder of Registrable Securities, the
officers, directors, members, partners, agents and employees (and any other individuals or entities with a functionally equivalent
role of a person holding such titles, notwithstanding a lack of such title or any other title) of each of them, each individual
or entity who controls the Buyer or any such holder of Registrable Securities (within the meaning of Section 15 of the 1933 Act
or Section 20 of the 1934 Act) and the officers, directors, members, stockholders, partners, agents and employees (and any other
individuals or entities with a functionally equivalent role of a person holding such titles, notwithstanding a lack of such title
or any other title) of each such controlling individual or entity (each, an “Indemnified Party”), to the fullest extent
permitted by applicable law, from and against any and all losses, claims, damages, liabilities, costs (including, without limitation,
reasonable attorneys’ fees) and expenses (collectively, “Losses”), as incurred, arising out of or relating
to (1) any untrue or alleged untrue statement of a material fact contained in a Registration Statement, any related prospectus
or any form of prospectus or in any amendment or supplement thereto or in any preliminary prospectus, or arising out of or relating
to any omission or alleged omission of a material fact required to be stated therein or necessary to make the statements therein
(in the case of any such prospectus or supplement thereto, in light of the circumstances under which they were made) not misleading
or (2) any violation or alleged violation by the Company of the 1933 Act, the 1934 Act or any state securities law, or any rule
or regulation thereunder, in connection with the performance of its obligations under this Exhibit E, except to the extent, but
only to the extent, that (i) such untrue statements or omissions are based upon information regarding the Buyer or such holder
of Registrable Securities furnished to the Company by such party for use therein. The Company shall notify the Buyer and each
holder of Registrable Securities promptly of the institution, threat or assertion of any proceeding arising from or in connection
with the transactions contemplated by this Exhibit E of which the Company is aware.

1.7 If
the indemnification under Section 1.6 is unavailable to an Indemnified Party or insufficient to hold an Indemnified Party harmless
for any Losses, then the Company shall contribute to the amount paid or payable by such Indemnified Party, in such proportion
as is appropriate to reflect the relative fault of the Company and Indemnified Party in connection with the actions, statements
or omissions that resulted in such Losses as well as any other relevant equitable considerations. The relative fault of the Company
and Indemnified Party shall be determined by reference to, among other things, whether any action in question, including any untrue
or alleged untrue statement of a material fact or omission or alleged omission of a material fact, has been taken or made by,
or relates to information supplied by, the Company or the Indemnified Party, and the parties’ relative intent, knowledge,
access to information and opportunity to correct or prevent such action, statement or omission. The amount paid or payable by
a party as a result of any Losses shall be deemed to include any reasonable attorneys’ or other fees or expenses incurred
by such party in connection with any proceeding to the extent such party would have been indemnified for such fees or expenses
if the indemnification provided for in Section 1.6 was available to such party in accordance with its terms. It is agreed that
it would not be just and equitable if contribution pursuant to this Section 1.7 were determined by pro rata allocation or by any
other method of allocation that does not take into account the equitable considerations referred to in the immediately preceding
sentence. Notwithstanding the provisions of this Section 1.7, neither the Buyer nor any holder of Registrable Securities shall
be required to contribute, in the aggregate, any amount in excess of the amount by which the net proceeds actually received by
such party from the sale of all of their Registrable Securities pursuant to such Registration Statement or related prospectus
exceeds the amount of any damages that such party has otherwise been required to pay by reason of such untrue or alleged untrue
statement or omission or alleged omission.
